                                 Loan Agreement


                  Loan Agreement dated as of January 1, 1999 between Atlas Air,
Inc., a Delaware corporation (the "Borrower"), and Michael A. Chowdry, an
individual whose mailing address is 538 Commons Drive, Golden, Colorado 80401
(the "Lender").

                  WHEREAS, the Borrower has agreed to acquire a new Boeing
Business Jet (737-700) corporate aircraft and all associated equipment and
documentation (the "BBJ"), and

                  WHEREAS, the Borrower has financed a portion of the
acquisition cost of the BBJ, pursuant to an Aircraft Lease Agreement dated as of
February 26, 1999 between General Electric Capital Corporation ("GECC") and the
Borrower (the "Lease"), and

                  WHEREAS, the Lender has agreed with the Borrower to make a
loan to Borrower in an amount described in Section 1 hereof.

                  NOW, THEREFORE, the Borrower and Lender hereby agree as
follows:

Section 1.             The Non Recourse Loan.

                  The Lender, on terms and conditions hereinafter set forth,
hereby agrees to make a non-recourse loan to the Borrower, bearing a floating
rate of interest equal to the London Interbank Offered Rate for one month as
shown in The Wall Street
<PAGE>
                                      -2-


Journal (the "LIBOR rate") in an amount equal to 50% of the amount by which the
sum of (a) the Acquisition Cost; (b) the cost of any capital improvements to the
BBJ subject to compliance with Section 5 hereof; and (c) any financing costs,
interest and lease payments with respect to the Lease exceeds the principal
amount of the purchase price received by the Borrower from GECC for sale of the
BBJ to GECC. For purposes of this Agreement, the "Acquisition Cost" shall be an
amount equal to the sum of the purchase price actually paid initially by
Borrower to acquire the BBJ, including all modifications and the installation of
the interior made prior to the time that the BBJ is placed in service, less
$9,164,518.20. The interest rate shall change monthly, with the LIBOR rate as
shown in The Wall Street Journal on the last business day of each month applied
to the next month (or part thereof).

Section 2.                 Advances.

                  (a) Upon the terms and subject to the conditions herein set
forth the Lender shall from time to time make advances (the "Advances") to the
Borrower under this Loan Agreement during the period from the date hereof until
the date of the sale by Borrower or disposition of the BBJ (the "Termination
Date") in response to Borrower's Request Notice referred to in paragraph (b) of
this Section 2.
<PAGE>
                                      -3-


                  (b) The Borrower shall give the Lender at least three (3)
Business Days' prior written or telegraphic notice of its request for an
Advance. Each such notice shall specify the date, the amount and the purpose of
the requested Advance and shall be in the form attached hereto as Exhibit B (a
"Request Notice"). The Lender shall make each Advance in immediately available
funds by wire transfer to a deposit account designated by Borrower at its
financial institution, as soon as practicable, but in no event later than 3
Business Days following the receipt by Lender of a Request Notice. The term
"Business Days" means any day other than a Saturday or Sunday and other than a
day which is a Federal legal holiday or a legal holiday for banks in the State
of Colorado.

                  (c) Each Advance shall be evidenced by a notation of the
amount of Advance set forth on Schedule I to the nonrecourse note in the form of
Exhibit A hereto (the "Note") delivered to the Lender at the time of the initial
Advance payment made hereunder. (The aggregate Advances made hereunder shall
sometimes be referred to herein as the "Loan".)

Section 3.              Repayment of Loan.

                  The Loan shall be non-recourse to the Borrower and shall be
repaid by the Borrower solely out of the Repayment Amount (as defined below).
Unless approved by Lender, Dispositions must be made for cash. Borrower shall
repay the Loan
<PAGE>
                                      -4-


promptly upon its receipt of the Repayment Amount, subject to the provisions of
Section 9 hereof. Lender shall have no recourse against the Borrower for
repayment of the Loan, except out of the Repayment Amount. In the event that the
Repayment Amount exceeds the aggregate Advances made by the Lender hereunder,
Lender shall be entitled to receive such excess amount.

                  "Repayment Amount" shall mean (i) 50% of the Net Proceeds (as
defined below) received by the Borrower with respect to the Disposition (as
defined below) of the BBJ, less (ii) the excess, if any, of $4,582,259.10 over
the present value (computed as of December 1, 1999 at a discount rate of 7.5%)
of 50% of the actual tax benefit realized by Borrower (as computed based on the
same parameters as used on Exhibit C annexed hereto and the same effective tax
rate as used in determining Net Proceeds) plus (iii) the excess, if any, of the
present value (computed as of December 1, 1999 at a discount rate of 7.5%) of
50% of the actual tax benefit realized by Borrower (as computed based on the
same parameters as used on Exhibit C annexed hereto and the same effective tax
rate as used in determining Net Proceeds) over $4,582,259.10 plus (iv) the tax
benefit, if any, realized by Borrower as a result of the payment to Lender of
the Repayment Amount.

                  "Net Proceeds" shall mean the aggregate cash proceeds received
by Borrower from time to time with respect to the Dispo-
<PAGE>
                                      -5-


sition of the BBJ, net of all of the following actually paid or, in the case of
(iv) reserved (i) commissions and other fees and expenses (including fees and
expenses of legal counsel and investment banks) paid to third parties in
connection with such Disposition, (ii) provisions for all taxes payable as a
result of the Disposition, including without limitation income taxes at the then
effective income tax rate for Borrower, (iii) payments made to terminate the
Lease and retire such other indebtedness as may have been approved in writing in
advance by the Lender, and (iv) appropriate amounts to be determined by the
Company as a reserve required in accordance with generally accepted accounting
principles ("GAAP") against liabilities associated with such Disposition;
provided that 50% of any such reserved amounts shall be paid to the Lender at
the earliest time such reserve is no longer required in accordance with GAAP.

                  "Disposition" shall mean the sale of the BBJ or the actual or
constructive total loss of the BBJ or requisition of title or use of such
property which results in an insurance settlement on the basis of total loss or
the seizure or condemnation of the BBJ.

Section 4.             Sale of BBJ.

                  (a) Borrower shall have the right to sell the BBJ at any time,
subject to giving Lender written notice of its decision to sell the BBJ and
giving Lender the right of first refusal to
<PAGE>
                                      -6-


purchase the BBJ. Such right may be exercised by the Lender by written notice to
the Borrower given at any time within 30 days of the Lender's receipt of such
notice and by the Lender closing on such purchase at any time within 60 days of
Lender's receipt of such notice, unless closing is prevented by the action or
inaction of the Borrower. If a proposed sale as to which the right of first
refusal applies specifies: (i) a consideration in other than United States
money, Lender shall have the right to purchase the BBJ for the United States
money equivalent of the specified consideration; and (ii) a manner, time, terms
or conditions that cannot be complied with without unreasonable effect, Lender
shall have the right to purchase the BBJ by complying with the reasonable
equivalent of the specified manner, time, terms or conditions.

                  (b) Lender shall have the right to cause the Borrower to sell
the BBJ at any time by giving the Borrower written notice of such request,
subject to giving the Borrower the right to retain ownership of the BBJ and to
make payment to the Lender as if such sale had been made at a price determined
as provided in Section 4(c) hereof.

                  (c) The price to be paid to Lender if the Borrower retains
ownership of the BBJ as stated above in Section 4(b) shall be at fair market
value, as determined by a mutually agreed independent appraiser. If the Borrower
receives a notice from
<PAGE>
                                      -7-


the Lender in accordance with paragraph (b) hereof, Borrower shall use
commercially reasonable efforts to sell the BBJ within 270 days of receiving
such notice. Borrower shall keep the Lender reasonably informed of its sale
efforts during this period.

Section 5.             Capital Improvements.

                  The Borrower hereby agrees that no capital improvements will
be made on the BBJ without the prior written consent of the Lender, except for
capital improvements required by (i) the Lease or (ii) FAA directives, rules or
regulations.

                  Notwithstanding any provisions to the contrary, the term
"capital improvements" as used in Section 1 and Section 10(b) shall: (i) include
the cost of all modifications and the installation of the interior made
subsequent to the time the BBJ is placed in service, but shall exclude (ii)
costs related to the overhaul, replacement, restoration or refurbishment of the
airframe, aircraft engines, landing gears or other parts and components of the
BBJ which overhaul, replacement, restoration, or refurbishment is caused by the
use of the aircraft.

Section 6.                 Covenants of Borrower.

                  So long as the Note shall remain outstanding, the Borrower
shall, unless the Lender shall otherwise consent in writing:
<PAGE>
                                      -8-


                  (a) Cause the BBJ to be operated and maintained in compliance
with the FAA rules and regulations and the Lease; provided that the Borrower
shall be solely responsible for the payment of all of the costs of such
operation and maintenance (including, without limitation, salaries, insurance,
fuel, and landing fees, and all other operating expenses).

                  (b) Not create or allow to exist any lien on the BBJ other
than (i) pursuant to the Lease, or (ii) as may be approved in writing by the
Lender in advance, and not to lease or otherwise transfer the BBJ except in
accordance with Section 4 hereof.

                  (c) The Borrower shall not amend, modify or grant a waiver
under any terms and conditions of the Lease without the prior consent of the
Lender.

Section 7.            Representations and Warranties of Borrower.

                  The Borrower hereby represents and warrants to the Lender as
follows:

                  Lender's obligation to make the initial Advance and each

                  (a) Borrower shall have duly executed and delivered to Lender:
(i) the Loan Agreement; and (ii) the Note; and

                  (b) The representations and warranties made by Borrower in

sentations and warranties made by Borrower in Section 7 hereof are true and
correct.

Lease or any other information or document which is received by the Borrower and

Borrower is entitled.

                  (b) In the event Lender defaults in its obligations under this
Loan Agreement, Lender shall not be entitled to receipt of any portion of the
Net Proceeds from the Disposition of the BBJ until Borrower has been repaid in

                           (AND ATLAS AIR OBLIGATION)


                                                                Golden, Colorado
                                                                October 15, 1999

               General

               References made to the Loan Agreement dated as of January 1, 1999
between Atlas Air, Inc., a Delaware corporation ("Payee or "Atlas Air"), and
Michael A. Chowdry ("Maker" or "Mr. Chowdry") relating to Atlas Air's
acquisition of a Boeing Business Jet (737-700) ("BBJ") from the Boeing Company
and Mr. Chowdry's agreement to loan Atlas Air, on a non-recourse basis, the
following: An amount (the "BBJ costs") equal to 50% of the amount by which the
sum of (a) the Acquisition Cost, (b) the cost of any capital improvements to the
BBJ (excluding costs related to the overhaul, replacement, restoration or
refurbishment of the BBJ's airframe, aircraft engines, landing gears or other
parts and components of the BBJ which overhaul, replacement, restoration or
refurbishment is caused by the use of the aircraft) and (c) any financing costs,
interest and lease payments with respect to the Aircraft Lease Agreement dated
as of February 26, 1999 between General Electric Credit Corporation ("GECC") and
Atlas Air, exceeds the principal amount of the purchase price received by Atlas
Air from GECC for the sale of the BBJ to GECC. As used above, the term
"Acquisition Cost" means an amount equal to the sum of the purchase price
actually paid initially by Atlas Air to acquire the BBJ, including all
modifications and the installation of the interior made prior to the time that
the BBJ is placed in service less $9,164,518.20.

               The amount of the BBJ costs at October 15, 1999 is less than
zero.

               Principal and Interest

               Maker, whose address is 538 Commons Drive, Golden, Colorado (or
such other address as Maker may designate in writing to Payee), promises to pay
to the order of Payee, at Payee's principal place of business, 538 Commons
Drive, Golden, CO 80401 (or such other address as Payee shall designate in
writing to Maker), the following principal sum, together with interest on the
unpaid principal sum from time to time outstanding at the rate per annum stated
below: The positive amount of BBJ costs (a) which (i) are paid by Payee prior to
the principal amount of this Note becoming due and (ii) have been entered by
Payee on
<PAGE>
                                      - 2 -


Schedule A to this Note and (b) for which Payee has concurrently given written
notice to Maker of entering the additional amount on Schedule A.

               The BBJ costs shall be deemed outstanding principal amounts on
the date on which both the amounts have been entered on Schedule A and notice of
entering them on Schedule A have been given to Maker.

               The outstanding principal of this Note shall bear a floating rate
of interest equal to the London Interbank Offered Rate for one month as shown in
The Wall Street Journal (the "LIBOR rate"). The initial interest rate shall be
the LIBOR rate as shown in The Wall Street Journal published on October 15,
1999. The interest rate shall change monthly, with the LIBOR rate as shown in
The Wall Street Journal on the last business day of each month applied to the
next month (or part thereof). Interest, based on a 365-day year, shall be
accrued for the number of days the principal sum (or any portion thereof) is
actually outstanding.

               The entire outstanding principal balance and all accrued but
unpaid interest shall be due and payable to Payee on the 30th day after Maker
receives written notice from Payee demanding payment of all outstanding
principal and accrued but unpaid interest (the "maturity date").

               Prepayment

               Principal and interest payments may be paid but are not required
to be paid prior to the maturity date. The privilege to prepay all or any part
of this Note without any penalty is reserved to Maker. However, any principal
prepayment must be accompanied by all interest on that amount then accrued, if
any.

               Application of Payment

               All payments on this Note shall be applied first to the payment
of accrued interest, and, after all such interest has been paid, any remainder
shall be applied to reduction of the principal balance. All amounts payable
hereunder are payable in lawful money of the United States of America.

               Attorneys' Fees

               Maker hereby agrees to pay reasonable attorneys' fees and all
other reasonable costs and expenses incurred, after a default in payment, in the
enforcement of this Note and the collection of amounts due hereunder, whether
such enforcement or collection is by court action or otherwise.

               Other

               This Note shall be governed as to validity, interpretation,
construction, effect and in all other respects by the laws and decisions of the
State of Colorado. Maker agrees that the federal and state courts located in the
State of Colorado shall have subject matter jurisdiction to entertain any action
brought to enforce or collect upon this Note and, by execution hereof,
voluntarily submits to personal jurisdiction of such courts; provided, however,
such jurisdiction shall not be exclusive and, at its option, Payee may commence
such action in any other court which otherwise has jurisdiction.

               No delay or omission in exercising any right or power hereunder,
shall affect the liability of Maker. No delay or omission by Payee in exercising
any power or right hereunder shall impair such right or power or be construed to
be a waiver of any default, nor shall any single or partial exercise of any
power or right hereunder preclude any or full exercise thereof or the exercise
of any other right or power. Each legal holder hereof shall have and may
exercise all the rights and powers given to Payee herein.

               This Note has been executed as of October 15, 1999 and actually
on the date indicated below.

                                  DEFINITIONS.

1.1   CERTAIN DEFINED TERMS.

      The following terms used in this Agreement shall have the following
meanings:

            "ACMI CONTRACT" means (i) any contract entered into by Company
pursuant to which Company furnishes the aircraft, crew, maintenance and
insurance and customers bear all other operating expenses and (ii) any similar
contract in which the customer provides the flight crew, all in accordance with
Company's historical practices.

            "ACMI CONTRACTED AIRCRAFT" means an aircraft acquired by Company or
its Subsidiaries and dedicated to a new ACMI Contract entered into in connection
with the acquisition of such aircraft (which ACMI Contract shall not represent a
renewal or replacement of a prior ACMI Contract unless the aircraft dedicated to
such prior ACMI Contract was operated under an operating lease and returned to
the lessor) which is in effect on the date of calculation and has a remaining
term of one year or more on the date such aircraft was dedicated to such ACMI
Contract (subject to cancellation terms, which may include the right to cancel
on six months notice). When making any calculation on a Pro Forma Basis effect
shall be given to the acquisition of an ACMI Contracted Aircraft by adding to
the appropriate components of Consolidated Adjusted EBITDA (i) the net projected
annualized revenues from the operation of the ACMI Contracted Aircraft under
such ACMI Contract for that portion of the period for which Consolidated
Adjusted EBITDA is being calculated prior to the acquisition of such aircraft,
assuming operation for the minimum guaranteed number of block hours (less any
block hours subject to cancellation) at the minimum guaranteed rate under such
ACMI Contract less (ii) the projected annualized cash operating expenses from
such operation for the same period for which the related projected revenues are
determined in clause (i) above; provided that such projected cash operating
expenses shall not be less on a per block hour basis than the average historical
per block hour operating expenses of Company for the four full fiscal quarters
immediately preceding the date of calculation, and provided, further, that if
such aircraft is of a model other than a Boeing 747 freighter, such projected
cash operating expenses shall include maintenance costs which shall not be less
than the average for such aircraft type disclosed on the most recently available
DOT Forms 41 with respect to such aircraft type or any summary of such data as
reported in a nationally recognized industry publication. For purposes of this
definition, "ACMI CONTRACT" shall include contracts pursuant to which Company
does not pay any crew costs, in which event pro forma effect shall be given as
described above but excluding from the projected annualized cash operating
expenses all crew costs. Cash operating expenses means for purposes of this
definition consolidated operating expenses, less consolidated depreciation and
amortization and Consolidated Rental Payments, to the extent included in
computing consolidated operating expenses.

            "ADJUSTED CONSOLIDATED WORKING CAPITAL" means, as at any date of


                                      -2-

Determination Date, (x) until such time as Reference Lenders are determined in

Telerate Access Service Page 3750 (British Bankers Association Settlement Rate)

a.m. (London time) on such Interest Rate Determination Date for U.S. dollar

Eurodollar Rate Loan for which the Adjusted Eurodollar Rate is then being
determined with maturities comparable to the Interest Period for which such
Adjusted Eurodollar Rate will apply by (ii) a percentage equal to 100% minus the
stated maximum rate of all reserve requirements (including, without limitation,
any marginal, emergency, supplemental, special or other reserves) applicable on
such Interest Rate Determination Date to any member bank of the Federal Reserve
System in respect of "Eurodollar liabilities" as defined in Regulation D (or any
successor category of liabilities under Regulation D) and (y) thereafter, the
rate per annum obtained by dividing (i) the arithmetic average (rounded upward
to the nearest 1/16 of one percent) of the offered quotation, if any, to first
class banks in the interbank Eurodollar market by each of the Reference Lenders
for U.S. dollar deposits of amounts in same day funds comparable to the
principal amount of the Eurodollar Rate Loan of that Reference Lender for which
the Adjusted Eurodollar Rate is then being determined with maturities comparable
to such Interest Period as of approximately 10:00 A.M. (New York time) on such
Interest Rate Determination Date by (ii) a percentage equal to 100% minus the
stated maximum rate of all reserve requirements (including, without limitation,
any marginal, emergency, supplemental, special or other reserves) applicable on
such Interest Rate Determination Date to any member bank of the Federal Reserve
System in respect of "Eurocurrency liabilities" as defined in Regulation D (or
any successor category of liabilities under Regulation D); provided that if any
Reference Lender fails to provide Administrative Agent with its aforementioned
quotation then the Adjusted Eurodollar Rate shall be determined based on the
quotation(s) provided to Administrative Agent by the other Reference Lender(s).

            "ADMINISTRATIVE AGENT" has the meaning assigned to that term in the
introduction to this Agreement and also means and includes any successor
Administrative Agent appointed pursuant to subsection 8.6.

            "AERONAUTICAL AUTHORITY" means, at any date, the Federal Aviation

Rata Shares, it being understood that no Lender shall be responsible for any
default by any other Lender in that other Lender's obligation to make a Loan
requested hereunder nor shall the Commitment of any Lender to make the
particular type of Loan requested be increased or decreased as a result of a
default by any other Lender in that other Lender's obligation to make a Loan
requested hereunder. Promptly after receipt by Administrative Agent of a Notice
of Borrowing pursuant to subsection 2.1B (or telephonic notice in lieu thereof),

such Funding Date, Administrative Agent may assume that such Lender has made
such amount available to Administrative Agent on such Funding Date and
Administrative Agent may, in its sole discretion, but shall not be obligated to,
make available to Company a corresponding amount on such Funding Date. If such
corresponding amount is not in fact made available to Administrative Agent by
such Lender, Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender together with interest thereon,
for each day from such Funding Date until the date such amount is paid to
Administrative Agent, at the customary rate set by Administrative Agent for the
correction of errors among banks for three Business Days and thereafter at the
Base Rate. If such Lender does not pay such corresponding amount forthwith upon
Administrative Agent's demand therefor, Administrative Agent shall promptly
notify Company and Company shall immediately pay such corresponding amount to
Administrative Agent together with interest thereon, for each


                                      -32-
<PAGE>
day from such Funding Date until the date such amount is paid to Administrative
Agent, at the rate payable under this Agreement for Base Rate Loans. Nothing in

      such authority or consent, is listed in the Register as a Lender shall be
      conclusive and binding on any subsequent holder, assignee or transferee of
      the corresponding Commitments or Loans.

            (v) Company hereby designates Administrative Agent to serve as
      Company's agent solely for purposes of maintaining the Register as
      provided in this subsection 2.1E, and Company hereby agrees that, to the
      extent Administrative Agent serves in such capacity, Administrative Agent
      and its officers, directors, employees, agents and affiliates shall
      constitute Indemnities for all purposes under subsection 9.3.

2.2   INTEREST ON THE LOANS.

      A. RATE OF INTEREST. Subject to the provisions of subsections 2.6 and 2.7,
each Loan shall bear interest on the unpaid principal amount thereof from the
date made through maturity (whether by acceleration or otherwise) at a rate
determined by reference to the Base Rate or the Adjusted Eurodollar Rate, as the
case may be. The applicable basis for determining the rate of interest with
respect to any Loan shall be selected by Company initially at the time a Notice
of Borrowing is given with respect to such Loan pursuant to subsection 2.1B. The
basis for determining the interest rate with respect to any Loan may be changed
from time to time pursuant to subsection 2.2D. If on any day a Loan is
outstanding with respect to which notice has not been delivered to
Administrative Agent in accordance with the terms of this Agreement specifying
the applicable basis for determining the rate of interest, then for that day
that Loan shall bear interest determined by reference to the Base Rate.

      Subject to the provisions of subsections 2.2E and 2.7, each Loan shall
bear interest through maturity as follows:

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

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

      The "APPLICABLE MARGIN" for each Base Rate Loan and Eurodollar Rate Loan
shall be the percentage set forth below for that type of Loan for the periods
set forth below.

      Notwithstanding the foregoing, the Applicable Margin shall be reduced in
an amount equal to the applicable Pricing Reduction effective from the date
following the delivery by Company to Administrative Agent of a Pricing
Certificate through the date a subsequent Pricing Certificate is required to be
delivered. If Company fails to deliver a Pricing Certificate or delivers an
incorrect Pricing Certificate, no Pricing Reduction shall be effective until
Company delivers a correct Pricing Certificate.

      B. INTEREST PERIODS. In connection with each Eurodollar Rate Loan, Company
may, pursuant to the applicable Notice of Borrowing or Notice of
Conversion/Continuation, as the case may be, select an interest period (each an
"INTEREST PERIOD") to be applicable to such Loan, which Interest Period shall
be, at Company's option, either a one, two, three or six month period; provided
that:

            (i) the initial Interest Period for any Eurodollar Rate Loan shall
      commence on the Funding Date in respect of such Loan, in the case of a
      Loan initially made as a Eurodollar Rate Loan, or on the date specified in
      the applicable Notice of Conversion/Continuation, in the case of a Loan
      converted to a Eurodollar Rate Loan;

            (ii) in the case of immediately successive Interest Periods
      applicable to a Eurodollar Rate Loan continued as such pursuant to a
      Notice of Conversion/Continuation, each successive Interest Period shall
      commence on the day


                                      -35-
<PAGE>
      on which the next preceding Interest Period expires;

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

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

            (v) no Interest Period with respect to any portion of the Loans
      shall extend beyond the Final Scheduled Maturity Date.

            (vi) no Interest Period with respect to any portion of the Loans
      shall extend beyond a date on which Company is required to make a
      scheduled payment of principal of the Loans unless the sum of (a) the
      aggregate principal amount of Loans that are Base Rate Loans plus (b) the
      aggregate principal amount of Loans that are Eurodollar Rate Loans with
      Interest Periods expiring on or before such date equals or exceeds the
      principal amount required to be paid on the Loans on such date;

            (vii) there shall be no more than twelve Interest Periods
      outstanding at any time;

            (viii) in the event Company fails to specify an Interest Period for
      any Eurodollar Rate Loan in the applicable Notice of Borrowing or Notice
      of Conversion/Continuation, Company shall be deemed to have selected an
      Interest Period of one month; and

            (ix) prior to the date that is three months from the Fourth
      Restatement Date, no Interest Period with respect to any portion of the
      Loans shall exceed one month.

      C. INTEREST PAYMENTS. Subject to the provisions of subsection 2.2E,
interest on each Loan shall be payable in arrears on and to each Interest
Payment Date applicable to that Loan, upon any prepayment of that Loan (to the
extent accrued on the amount being prepaid) and at maturity (including final
maturity).

      D. CONVERSION OR CONTINUATION. Subject to the provisions of subsection
2.6, Company shall have the option (i) to convert at any time all or any part of
its outstanding Loans equal to $3,000,000 and integral multiples of $100,000 in
excess of that amount from Loans bearing interest at a rate determined by
reference to one basis to Loans bearing interest at a rate determined by
reference to an alternative basis or (ii) upon the expiration of any


                                      -36-
<PAGE>
Interest Period applicable to a Eurodollar Rate Loan, to continue all or any
portion of such Loan equal to $3,000,000 and integral multiples of $100,000 in
excess of that amount as a Eurodollar Rate Loan; provided, however, that a
Eurodollar Rate Loan may only be converted into a Base Rate Loan on the
expiration date of an Interest Period applicable thereto.

      Company shall deliver a Notice of Conversion/Continuation to
Administrative Agent no later than 12:00 Noon (New York time) at least one
Business Day in advance of the proposed conversion date (in the case of a
conversion to a Base Rate Loan) and at least three Business Days in advance of
the proposed conversion/continuation date (in the case of a conversion to, or a
continuation of, a Eurodollar Rate Loan). A Notice of Conversion/Continuation
shall specify (i) the proposed conversion/continuation date (which shall be a
Business Day), (ii) the amount and type of the Loan to be converted/continued,
(iii) the nature of the proposed conversion/continuation, (iv) in the case of a
conversion to, or a continuation of, a Eurodollar Rate Loan, the requested
Interest Period, and (v) in the case of a conversion to, or a continuation of, a
Eurodollar Rate Loan, that no Potential Event of Default or Event of Default has
occurred and is continuing. In lieu of delivering the above-described Notice of
Conversion/Continuation, Company may give Administrative Agent telephonic notice
by the required time of any proposed conversion/continuation under this
subsection 2.2D; provided that such notice shall be promptly confirmed in
writing by delivery of a Notice of Conversion/Continuation to Administrative
Agent on or before the proposed conversion/continuation date.

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

      Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice
of Conversion/Continuation for conversion to, or continuation of, a Eurodollar
Rate Loan (or telephonic notice in lieu thereof) shall be irrevocable on and
after the related Interest Rate Determination Date, and Company shall be bound
to effect a conversion or continuation in accordance therewith.

      E. DEFAULT RATE. Upon the occurrence and during the continuation of any
Event of Default, the outstanding principal amount of all Loans and, to the
extent permitted by applicable law, any interest payments thereon not paid when
due and any fees and other amounts then due and payable hereunder, shall
thereafter bear interest (including post-petition interest in any proceeding
under the Bankruptcy Code or other applicable bankruptcy laws) payable upon
demand at a rate that is 2% per annum in excess of the interest rate otherwise


                                      -37-
<PAGE>
payable under this Agreement with respect to the applicable Loans (or, in the
case of any such fees and other amounts, at a rate which is 2% per annum in
excess of the interest rate otherwise payable under this Agreement for Base Rate
Loans); provided that, in the case of Eurodollar Rate Loans, upon the
expiration of the Interest Period in effect at the time any such increase in
interest rate is effective such Eurodollar Rate Loans shall thereupon become
Base Rate Loans and shall thereafter bear interest payable upon demand at a rate
which is 2% per annum in excess of the interest rate otherwise payable under
this Agreement for Base Rate Loans. Payment or acceptance of the increased rates
of interest provided for in this subsection 2.2E is not a permitted alternative
to timely payment and shall not constitute a waiver of any Event of Default or
otherwise prejudice or limit any rights or remedies of Administrative Agent or
any Lender.

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

2.3   FEES.

      A. COMMITMENT FEES. Company agrees to pay to Administrative Agent, for
distribution to each Lender in proportion to that Lender's Pro Rata Share,
commitment fees for the period from and including the Fourth Restatement Date to
and excluding the Revolving Loan Commitment Termination Date equal to the
average of the daily excess of the Revolving Loan Commitments over the aggregate
principal amount of Loans outstanding multiplied by (y) if a Pricing Reduction
is not then in effect, 0.50% per annum or (z) if a Pricing Reduction is then in
effect, 0.375% per annum, such commitment fees to be calculated on the basis of
a 360-day year and the actual number of days elapsed and to be payable quarterly
in arrears on March 31, June 30, September 30 and December 31 of each year,
commencing on the first such date to occur after the Fourth Restatement Date,
and on the Revolving Loan Commitment Termination Date.

      B. ADMINISTRATIVE FEE. Company agrees to pay to Administrative Agent, an
Administrative Agent's fee in the amount as from time to time agreed upon by
Company and Administrative Agent.

      C. OTHER FEES. Company agrees to pay to Administrative Agent such other
fees

            subsection 2.6D), the Loans in an amount equal to the Net Cash
            Proceeds of such Asset Sale; provided that, with respect to Asset
            Sales which do not include the sale of a Financed Aircraft, so long
            as no Potential Event of Default or Event of Default has occurred
            and is continuing, (i) Company shall have the option to use the Net
            Cash Proceeds within one hundred eighty (180) days of receipt
            thereof for the purpose of making Consolidated Capital Expenditures
            otherwise permitted by this Agreement and (ii) to the extent such
            Net Cash Proceeds are not reinvested pursuant to clause (i), Company
            may retain Net Cash Proceeds in respect of such Asset Sales of up to
            $10 million in any Fiscal Year and $20 million in the aggregate;
            provided further that, with respect to any Asset Sale involving the
            sale of a Financed Aircraft, so long as no Potential Event of
            Default or Event of Default has occurred and is continuing, the
            Company may retain any Net Cash Proceeds in excess of the amount
            equal to the sum of (x) the amount required to repay all amounts
            outstanding under the Notes relating to such Financed Aircraft and
            (y) the amount required to prepay any remaining Loans to the extent
            necessary so that the outstanding principal amount of any Loans made
            to finance the acquisition or conversion of a Financed Aircraft
            shall not exceed 80% of the Appraised Value of such Financed
            Aircraft as determined by appraisals to be provided at the time of
            such mandatory prepayment by two Approved Appraisers. Concurrently
            with any prepayment of the Loans pursuant to this subsection
            2.4B(iii)(a), Company shall deliver to Administrative Agent an
            Officers' Certificate demonstrating the derivation of the Net Cash
            Proceeds of the correlative Asset Sale from the gross sales price
            thereof and the amount required to be prepaid pursuant to this
            subsection 2.4B(iii)(a). In the event that Company shall, at any
            time after receipt of Cash Proceeds of any Asset Sale requiring a
            prepayment pursuant to this subsection 2.4B(iii)(a), determine that
            the prepayments previously made in respect of such Asset Sale were
            in an aggregate amount less than that required by the terms of this
            subsection 2.4B(iii)(a), Company shall promptly make an additional


                                      -41-
<PAGE>
            prepayment of the Loans in the manner described above in an amount
            equal to the amount of any such deficit, and Company shall
            concurrently therewith deliver to Administrative Agent an Officers'
            Certificate demonstrating the derivation of the additional Net Cash
            Proceeds resulting in such deficit and the additional amount
            required to be prepaid pursuant to this subsection 2.4B(iii)(a). Any
            mandatory prepayments pursuant to this subsection 2.4B(iii)(a) shall
            be applied as specified in subsection 2.4B(iv). Notwithstanding the
            foregoing, so long as the AFL III Financing remains outstanding,
            Cash Proceeds from the sale or other disposition of the AFL III
            Equipment shall not be subject to the provisions of this subsection
            2.4(B)(iii)(a) to the extent that such Cash Proceeds are applied in
            accordance with the terms of the AFL III Financing Agreement.

                  (b) Prepayments and Reductions Due to Issuance of Certain
            Indebtedness. On the date of receipt by Company of the cash proceeds
            (net of underwriting discounts and commissions and other reasonable
            costs associated therewith) from the issuance of Permitted Extension
            Indebtedness with respect to a Financed Aircraft, Company shall
            prepay, without premium or penalty (other than pursuant to
            subsection 2.6D), the Loans in an amount equal to such net cash
            proceeds. Any such mandatory prepayments shall be applied as
            specified in subsection 2.4B(iv). Notwithstanding the foregoing, any
            such cash proceeds received pursuant to the AFL III Financing
            Agreement shall not be subject to the provisions of this subsection
            2.4(B)(iii)(b).

                  (c) Prepayments and Reductions Due to Insurance and
            Condemnation Proceeds. No later than the second Business Day
            following the date of receipt by Company or any of its Subsidiaries
            of any cash payments under any of the casualty insurance policies
            covering damage to or loss of property maintained pursuant to
            subsection 5.4 resulting from damage to or loss of all or any
            portion of the Collateral or any other tangible asset (net of actual
            and documented reasonable costs incurred by Company in connection
            with adjustment and settlement thereof, "INSURANCE PROCEEDS") or any
            proceeds resulting from the taking of assets by the power of eminent
            domain, condemnation or otherwise (net of actual and documented
            reasonable costs incurred by Company in connection with adjustment
            and settlement thereof, "CONDEMNATION PROCEEDS") (other than (x) the
            portion of such proceeds promptly applied to repair or replace the
            property in respect of which such proceeds were paid, (y) the
            portion of such proceeds required to be paid to Lien holders on
            aircraft other than Financed Aircraft or (z) proceeds applied
            pursuant to subsection 2.4B(iii)(d)), Company shall prepay, without
            premium or penalty (other than pursuant to subsection 2.6D), the
            Loans in an amount equal to such proceeds. Company shall, no later
            than 180 days after receipt of any such Insurance Proceeds or
            Condemnation Proceeds that have not


                                      -42-

                  theretofore been applied to the Obligations, make an
                  additional prepayment of Loans, in the manner described above,
                  in the full amount of all such proceeds that have not then
                  been applied to repair or replace the property in respect of
                  which such proceeds were paid. Any such mandatory prepayments
                  shall be applied as specified in subsection 2.4B(iv).
                  Notwithstanding the foregoing so long as (i) the AFL III
                  Financing remains outstanding, Insurance Proceeds and
                  Condemnation Proceeds with respect to the AFL III Equipment
                  shall not be subject to the provisions of this subsection
                  2.4(B)(iii)(c) to the extent such proceeds are applied in
                  accordance with the terms of the AFL III Financing Agreement.

                           (d) Prepayments and Reductions Due to an Event of
                  Loss. No later than the earlier of (x) the second Business Day
                  following the date of receipt by Company or any of its
                  Subsidiaries of any Insurance Proceeds or Condemnation
                  Proceeds with respect to a Financed Aircraft or (y) 180 days
                  following an Event of Loss with respect to a Financed
                  Aircraft, Company shall prepay, without premium or penalty
                  (other than pursuant to subsection 2.6D), the Loans associated
                  with such Financed Aircraft; provided that Company and its
                  Subsidiaries shall not be required to make a prepayment
                  pursuant to this subsection 2.4B(iii)(d) with respect to any
                  proceeds applied pursuant to Section 4(f)(vi)(A) or
                  4(f)(vi)(B) of any Aircraft Chattel Mortgage.

                           (e) Prepayments and Reductions from Consolidated
                  Excess Cash Flow. In the event that there shall be
                  Consolidated Excess Cash Flow for any Fiscal Year, within 100
                  days after the last day of such Fiscal Year Company shall
                  prepay, without premium or penalty (other than pursuant to
                  subsection 2.6D), the Loans in an amount equal to 50% of such
                  Consolidated Excess Cash Flow; provided that, if as of the
                  last day of such Fiscal Year, the aggregate principal amount
                  of all Loans was less than 60% of the aggregate Appraised
                  Value of all Financed Aircraft, no prepayment will be required
                  under this subsection 2.4B(iii)(e). Any such mandatory
                  prepayments shall be applied as specified in subsection
                  2.4B(iv).

                           (f) Prepayments Due to Reductions in Appraised Value.
                  Company shall from time to time prepay, without premium or
                  penalty (other than pursuant to subsection 2.6D), the Loans to
                  the extent necessary so that the outstanding principal amount
                  of any Loans made to finance the acquisition or conversion of
                  a Financed Aircraft shall not at any time exceed 80% of the
                  Appraised Value of such Financed Aircraft as most recently
                  determined pursuant to subsection 5.10; provided that, in lieu
                  of making a prepayment hereunder, Company may provide
                  Administrative Agent for the benefit of Lenders with cash
                  collateral or a letter of credit in the amount of such
                  prepayment pursuant to arrangements in form and substance
                  satisfactory to


                                      -43-
<PAGE>
                  Administrative Agent.

                           (g) Prepayments Due to Failure to Register Aircraft
                  with the FAA. In the event that, with respect to any Financed
                  Aircraft, Administrative Agent's security interest in such
                  Financed Aircraft is not fully perfected within five (5)
                  Business Days of the funding of Loans with respect to such
                  Financed Aircraft, Company shall prepay the full amount of
                  such Loans.

                  (iv)     Application of Prepayments.

                           (a) Application of Voluntary Prepayments by Type of
                  Loans and Order of Maturity. Any voluntary prepayments
                  pursuant to subsection 2.4B(i) shall be applied ratably among
                  the Notes relating to all of the Financed Aircraft; provided
                  that, Company may elect to apply any such prepayment first to
                  the Loans made with respect to a specific Financed Aircraft so
                  long as no Event of Default has occurred and continuing;
                  provided further that, at Administrative Agent's election, any
                  prepayment may be deemed first to prepay Loans made to finance
                  labor costs associated with conversion, if any, second to
                  prepay Loans made to finance other costs of conversion of a
                  Financed Aircraft and thereafter to all other Loans. Any
                  voluntary prepayments of the Existing Aircraft Loans and the
                  New Aircraft Term Loans pursuant to subsection 2.4B(i) shall
                  be applied to reduce the scheduled installments of principal
                  of the Existing Aircraft Loans or the New Aircraft Term Loans,
                  as the case may be, in inverse order of maturity.

                           (b) Application of Mandatory Prepayments of Loans.
                  Any mandatory prepayments of the Loans pursuant to subsection
                  2.4B(iii) shall be applied ratably among the Notes relating to
                  all of the Financed Aircraft; provided that in the event a
                  prepayment pursuant to subsection 2.4B(iii)(a) relates to
                  Financed Aircraft, such prepayment shall be applied first to
                  the Notes relating to such Financed Aircraft, second to Notes
                  relating to the remaining Financed Aircraft as required to
                  reduce the amount of the Loans financing such Financed
                  Aircraft to no more that 80% of the Appraised Value of such
                  Financed Aircraft as determined by the Appraised as required
                  by subsection 2.4B(iii)(a) and third ratably among the Notes
                  relating to all remaining Financed Aircraft; provided further
                  that in the event a prepayment pursuant to subsection
                  2.4B(iii)(b), (c), (d), (f) or (g) relates to Financed
                  Aircraft, such prepayment shall be applied first to the Notes
                  relating to such Financed Aircraft and second ratably among
                  the Notes relating to all other Financed Aircraft; provided
                  further that, at Administrative Agent's election, any such
                  prepayment may be deemed first to prepay Loans made to finance
                  labor costs associated with conversion, if any, second to
                  prepay Loans made to finance other costs of conversion of a
                  Financed Aircraft and thereafter to all other


                                      -44-
<PAGE>
                  Loans. Any mandatory prepayments of the Existing Aircraft
                  Loans and the New Aircraft Term Loans pursuant to subsection
                  2.4B(iii) shall be applied to reduce the scheduled
                  installments of principal of the Existing Aircraft Loans or
                  the New Aircraft Term Loans, as the case may be, in inverse
                  order of maturity.

                           (c) Application of Prepayments to Base Rate Loans and
                  Eurodollar Rate Loans. Any prepayment of Loans shall be
                  applied first to Base Rate Loans to the full extent thereof
                  before application to Eurodollar Rate Loans, in each case in a
                  manner which minimizes the amount of any payments required to
                  be made by Company pursuant to subsection 2.6D.

         C.       GENERAL PROVISIONS REGARDING PAYMENTS.

                  (i) Manner and Time of Payment. All payments by Company of
         principal, interest, fees and other Obligations hereunder and under the
         Notes shall be made in Dollars in same day funds, without defense,
         set-off or counterclaim, free of any restriction or condition, and
         delivered to Administrative Agent not later than 12:00 Noon (New York
         time) on the date due at the Funding and Payment Office for the account
         of Lenders; funds received by Administrative Agent after that time on
         such due date shall be deemed to have been paid by Company on the next
         succeeding Business Day. Company hereby authorizes Administrative Agent
         to charge its accounts with Administrative Agent in order to cause
         timely payment to be made to Administrative Agent of all principal,
         interest, fees and expenses due hereunder (subject to sufficient funds
         being available in its accounts for that purpose).

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

                  (iii) Apportionment of Payments. Aggregate principal and
         interest payments in respect of Loans shall be apportioned among all
         outstanding Loans to which such payments relate, in each case
         proportionately to Lenders' respective Pro Rata Shares. Administrative
         Agent shall promptly distribute to each Lender, at its primary address
         set forth below its name on the appropriate signature page hereof or at
         such other address as such Lender may request, its Pro Rata Share of
         all such payments received by Administrative Agent and the commitment
         fees of such Lender when received by Administrative Agent pursuant to
         subsection 2.3. Notwithstanding the foregoing provisions of this
         subsection 2.4C(iii), if, pursuant to the provisions of subsection
         2.6C, any Notice of Conversion/Continuation is withdrawn as to any
         Affected Lender or if any Affected Lender makes Base Rate Loans in lieu
         of its Pro Rata Share of any Eurodollar Rate Loans, Administrative
         Agent shall give effect thereto in apportioning payments received
         thereafter.


                                      -45-
<PAGE>
                  (iv) Payments on Business Days. Whenever any payment to be
         made hereunder shall be stated to be due on a day that is not a
         Business Day, such payment shall be made on the next succeeding
         Business Day and such extension of time shall be included in the
         computation of the payment of interest hereunder or of the commitment
         fees hereunder, as the case may be.

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

2.5      USE OF PROCEEDS.

         A. EXISTING AIRCRAFT EXTENDED LOANS. The proceeds of the Existing
Aircraft Extended Loans were used to finance the purchase and renovation of the
Existing Aircraft as shown on Schedule 1.1 annexed hereto.

         B. NEW AIRCRAFT LOANS. The proceeds of New Aircraft Loans shall be
applied to finance (i) the purchase of an Eligible Aircraft pursuant to a
Purchase Agreement in an amount up to the lesser of the purchase price of such
Eligible Aircraft and 80% of the Appraised Value of such Eligible Aircraft (but
without giving effect to any contemplated modifications) and/or (ii) the cost of
making a Financed Aircraft usable by Company as a cargo aircraft by paying for
those modifications identified in any Modification Agreement and any BFE
Agreement (but not for maintenance costs) in an amount that when added to the
amount financed in (i) does not exceed 80% the Appraised Value of such modified
Eligible Aircraft; provided that the final Revolving Loan to finance the
modification of such Eligible Aircraft may be in an amount equal to the lesser
of (x) 100% of the costs of modification associated with such final Revolving
Loan and (y) an amount which, when added to all other Revolving Loans made with
respect to such Eligible Aircraft, does not exceed 80% of the Appraised Value of
such Eligible Aircraft after giving effect to the completion of modification.

         C. MARGIN REGULATIONS. No portion of the proceeds of any borrowing
under this Agreement shall be used by Company or any of its Subsidiaries in any
manner that might cause the borrowing or the application of such proceeds to
violate Regulation U, Regulation T or Regulation X of the Board of Governors of
the Federal Reserve System or any other regulation of such Board or to violate
the Exchange Act, in each case as in effect on the date or dates of such
borrowing and such use of proceeds.

2.6      SPECIAL PROVISIONS GOVERNING EURODOLLAR RATE LOANS.

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

         A. DETERMINATION OF APPLICABLE INTEREST RATE. As soon as practicable
after 10:00 A.M. (New York time) on each Interest Rate Determination Date,
Administrative Agent shall determine (which determination shall, absent manifest
error, be final, conclusive and binding upon all parties) the interest rate that
shall apply to the Eurodollar Rate Loans for which an interest rate is then
being determined for the applicable Interest Period and shall promptly give
notice thereof (in writing or by telephone confirmed in writing) to Company and
each Lender.

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

         C. ILLEGALITY OR IMPRACTICABILITY OF EURODOLLAR RATE LOANS. In the
event that on any date any Lender shall have determined (which determination
shall be final and conclusive and binding upon all parties hereto but shall be
made only after consultation with Company and Administrative Agent) that the
making, maintaining or continuation of its Eurodollar Rate Loans (i) has become
unlawful as a result of compliance by such Lender in good faith with any law,
treaty, governmental rule, regulation, guideline or order (or would conflict
with any such treaty, governmental rule, regulation, guideline or order not
having the force of law even though the failure to comply therewith would not be
unlawful) or (ii) has become impracticable, or would cause such Lender material
hardship, as a result of contingencies occurring after the date of this
Agreement which materially and adversely affect the interbank Eurodollar market
or the position of such Lender in that market, then, and in any such event, such
Lender shall be an "AFFECTED LENDER" and it shall on that day give notice (by
telefacsimile or by telephone confirmed in writing) to Company and
Administrative Agent of such determination (which notice Agent shall promptly
transmit to each other Lender). Thereafter (a) the obligation of the Affected
Lender to make Loans as, or to convert Loans to, Eurodollar Rate Loans shall be
suspended until such notice shall be withdrawn by the


                                      -47-
<PAGE>
Affected Lender, (b) to the extent such determination by the Affected Lender
relates to a Eurodollar Rate Loan then being requested by Company pursuant to a
Notice of Borrowing or a Notice of Conversion/Continuation, the Affected Lender
shall make such Loan as (or convert such Loan to, as the case may be) a Base
Rate Loan, (c) the Affected Lender's obligation to maintain its outstanding
Eurodollar Rate Loans (the "AFFECTED LOANS") shall be terminated at the earlier
to occur of the expiration of the Interest Period then in effect with respect to
the Affected Loans or when required by law, and (d) the Affected Loans shall
automatically convert into Base Rate Loans on the date of such termination.
Notwithstanding the foregoing, to the extent a determination by an Affected
Lender as described above relates to a Eurodollar Rate Loan then being requested
by Company pursuant to a Notice of Borrowing or a Notice of
Conversion/Continuation, Company shall have the option, subject to the
provisions of subsection 2.6D, to rescind such Notice of Borrowing or Notice of
Conversion/Continuation as to all Lenders by giving notice (by telefacsimile or
by telephone confirmed in writing) to Administrative Agent of such rescission on
the date on which the Affected Lender gives notice of its determination as
described above (which notice of rescission Administrative Agent shall promptly
transmit to each other Lender). Except as provided in the immediately preceding
sentence, nothing in this subsection 2.6C shall affect the obligation of any
Lender other than an Affected Lender to make or maintain Loans as, or to convert
Loans to, Eurodollar Rate Loans in accordance with the terms of this Agreement.

         D. COMPENSATION FOR BREAKAGE OR NON-COMMENCEMENT OF INTEREST PERIODS.
Company shall compensate each Lender, upon written request by that Lender (which
request shall set forth the basis for requesting such amounts), for all
reasonable losses, expenses and liabilities (including, without limitation, any
interest paid by that Lender to lenders of funds borrowed by it to make or carry
its Eurodollar Rate Loans and any loss, expense or liability sustained by that
Lender in connection with the liquidation or re-employment of such funds) which
that Lender may sustain: (i) if for any reason (other than a default by that
Lender) a borrowing of any Eurodollar Rate Loan does not occur on a date
specified therefor in a Notice of Borrowing or a telephonic request for
borrowing, or a conversion to or continuation of any Eurodollar Rate Loan does
not occur on a date specified therefor in a Notice of Conversion/Continuation or
a telephonic request for conversion or continuation, (ii) if any prepayment or
other principal payment or any conversion of any of its Eurodollar Rate Loans
occurs on a date prior to the last day of an Interest Period applicable to that
Loan, (iii) if any prepayment of any of its Eurodollar Rate Loans is not made on
any date specified in a notice of prepayment given by Company, or (iv) as a
consequence of any other default by Company in the repayment of its Eurodollar
Rate Loans when required by the terms of this Agreement.

         E. BOOKING OF EURODOLLAR RATE LOANS. Any Lender may make, carry or
transfer Eurodollar Rate Loans at, to, or for the account of any of its branch
offices or the office of an Affiliate of that Lender.

         F. ASSUMPTIONS CONCERNING FUNDING OF EURODOLLAR RATE LOANS. Calculation
of all amounts payable to a Lender under this subsection 2.6 and under
subsection 2.7A shall


                                      -48-
<PAGE>
be made as though that Lender had actually funded each of its relevant
Eurodollar Rate Loans through the purchase of a Eurodollar deposit bearing
interest at the rate obtained pursuant to clause (i) of the definition of
Adjusted Eurodollar Rate in an amount equal to the amount of such Eurodollar
Rate Loan and having a maturity comparable to the relevant Interest Period and
through the transfer of such Eurodollar deposit from an offshore office of that
Lender to a domestic office of that Lender in the United States of America;
provided, however, that each Lender may fund each of its Eurodollar Rate Loans
in any manner it sees fit and the foregoing assumptions shall be utilized only
for the purposes of calculating amounts payable under this subsection 2.6 and
under subsection 2.7A.

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

2.7      INCREASED COSTS; TAXES; CAPITAL ADEQUACY.

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

                  (i) subjects such Lender (or its applicable lending office) to
         any additional Tax (other than any Tax on the overall net income of
         such Lender) with respect to this Agreement or any of its obligations
         hereunder or any payments to such Lender (or its applicable lending
         office) of principal, interest, fees or any other amount payable
         hereunder;

                  (ii) imposes, modifies or holds applicable any reserve
         (including without limitation any marginal, emergency, supplemental,
         special or other reserve), special deposit, compulsory loan, FDIC
         insurance or similar requirement against assets held by, or deposits or
         other liabilities in or for the account of, or advances or loans by, or
         other credit extended by, or any other acquisition of funds by, any
         office of such


                                      -49-
<PAGE>
         Lender (other than any such reserve or other requirements with respect
         to Eurodollar Rate Loans that are reflected in the definition of
         Adjusted Eurodollar Rate); or

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

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

         B.       WITHHOLDING OF TAXES.

                  (i) Payments to Be Free and Clear. All sums payable by Company
         under this Agreement and the other Loan Documents shall be paid free
         and clear of and (except to the extent required by law) without any
         deduction or withholding on account of any Tax (other than a Tax on the
         overall net income of any Lender) imposed, levied, collected, withheld
         or assessed by or within the United States of America or any political
         subdivision in or of the United States of America or any other
         jurisdiction from or to which a payment is made by or on behalf of
         Company or by any federation or organization of which the United States
         of America or any such jurisdiction is a member at the time of payment.

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

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

                           (b) Company shall pay any such Tax before the date on
                  which penalties attach thereto, such payment to be made (if
                  the liability to pay is imposed on Company) for its own
                  account or (if that liability is imposed on


                                      -50-
<PAGE>
                  Administrative Agent or such Lender, as the case may be) on
                  behalf of and in the name of Administrative Agent or such
                  Lender;

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

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

         provided that no such additional amount shall be required to be paid to
         any Lender under clause (c) above except to the extent that any change
         after the date hereof (in the case of each Lender listed on the
         signature pages hereof) or after the date of the Assignment Agreement
         pursuant to which such Lender became a Lender (in the case of each
         other Lender) in any such requirement for a deduction, withholding or
         payment as is mentioned therein shall result in an increase in the rate
         of such deduction, withholding or payment from that in effect at the
         date of this Agreement or at the date of such Assignment Agreement, as
         the case may be, in respect of payments to such Lender.

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

                           (a) Each Lender that is organized under the laws of
                  any jurisdiction other than the United States or any state or
                  other political subdivision thereof (for purposes of this
                  subsection 2.7B(iii), a "NON-US LENDER") shall deliver to
                  Administrative Agent for transmission to Company, on or prior
                  to the Fourth Restatement Date (in the case of each Lender
                  listed on the signature pages hereof) or on the date of the
                  Assignment Agreement pursuant to which it becomes a Lender (in
                  the case of each other Lender), and at such other times as may
                  be necessary in the determination of Company or Administrative
                  Agent (each in the reasonable exercise of its discretion), (1)
                  two original copies of Internal Revenue Service Form 1001 or
                  4224 (or any successor forms), properly completed and duly
                  executed by such Lender, together with any other certificate
                  or statement of exemption required under the Internal Revenue
                  Code or the regulations issued thereunder to establish that
                  such Lender is not subject to deduction or withholding of
                  United States federal income tax with respect to any payments
                  to such Lender of principal, interest, fees or other amounts

<PAGE>
                  payable under any of the Loan Documents or (2) if such Lender
                  is not a "bank" or other Person described in Section 881(c)(3)
                  of the Internal Revenue Code and cannot deliver either
                  Internal Revenue Service Form 1001 or 4224 pursuant to clause
                  (1) above, a Certificate re Non-Bank Status together with two
                  original copies of Internal Revenue Service Form W-8 (or any
                  successor form), properly completed and duly executed by such
                  Lender, together with any other certificate or statement of
                  exemption required under the Internal Revenue Code or the
                  regulations issued thereunder to establish that such Lender is
                  not subject to deduction or withholding of United States
                  federal income tax with respect to any payments to such Lender
                  of interest payable under any of the Loan Documents.

                           (b) Each Lender required to deliver any forms,
                  certificates or other evidence with respect to United States
                  federal income tax withholding matters pursuant to subsection
                  2.7B(iii)(a) hereby agrees, from time to time after the
                  initial delivery by such Lender of such forms, certificates or
                  other evidence, whenever a lapse in time or change in
                  circumstances renders such forms, certificates or other
                  evidence obsolete or inaccurate in any material respect, such
                  Lender shall (1) deliver to Administrative Agent for
                  transmission to Company two new original copies of Internal
                  Revenue Service Form 1001 or 4224, or a Certificate re
                  Non-Bank Status and two original copies of Internal Revenue
                  Service Form W-8, as the case may be, properly completed and
                  duly executed by such Lender, together with any other
                  certificate or statement of exemption required in order to
                  confirm or establish that such Lender is not subject to
                  deduction or withholding of United States federal income tax
                  with respect to payments to such Lender under the Loan
                  Documents or (2) immediately notify Administrative Agent and
                  Company of its inability to deliver any such forms,
                  certificates or other evidence.

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


                                      -52-
<PAGE>
                  subsection 2.7B(iii)(a).

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

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

2.8      OBLIGATION OF LENDERS TO MITIGATE.

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

2.9      RELEASE OF COLLATERAL.

         Upon the prepayment of all Loans made with respect to a specific
Financed Aircraft pursuant to subsection 2.4B(iv)(a) hereof, Administrative
Agent, at the reasonable expense of Company, agrees to execute and deliver to
Company such documents as shall be reasonably satisfactory to Company to
evidence the release of the Liens granted pursuant to the Collateral Documents
with respect to such Financed Aircraft and shall use its best efforts to return
the originals of all Notes representing such Loans to Company, marked "Paid."

                                   SECTION 3.

                    COMPANY'S REPRESENTATIONS AND WARRANTIES

         In order to induce Lenders to enter into this Agreement and to make the
Loans, Company represents and warrants to each Lender, on the date of this
Agreement and on each Funding Date, that the following statements are true,
correct and complete:

4.1      ORGANIZATION, POWERS, QUALIFICATION, GOOD STANDING, BUSINESS AND
         SUBSIDIARIES.

         A. ORGANIZATION AND POWERS. Company is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware.
Company has all requisite corporate power and authority to own and operate its
properties, to carry on its business as now conducted and as proposed to be
conducted, to enter into the Loan Documents and to carry out the transactions
contemplated thereby.

         B. QUALIFICATION AND GOOD STANDING; AIR CARRIER CERTIFICATION. Company
is qualified to do business and in good standing in every jurisdiction where its
assets are located and wherever necessary to carry out its business and
operations, except in jurisdictions where the failure to be so qualified or in
good standing has not had and will not have a Material Adverse Effect. Company
is a "citizen of the United States" within the meaning of the Federal Aviation
Act (a "UNITED STATES CITIZEN") and holds an air carrier operating certificate
under the Federal Aviation Act for aircraft capable of carrying 10 or more
individuals or 6,000 pounds or more of cargo.

         C. SUBSIDIARIES. All of the Subsidiaries of Company as of the Fourth
Restatement Date are identified in Schedule 4.1 annexed hereto, as said Schedule
4.1 may be supplemented from time to time pursuant to the provisions of
subsection 5.1(xvii). The capital stock of each of the Subsidiaries of Company
identified in Schedule 4.1 annexed hereto (as so supplemented) is duly
authorized, validly issued, fully paid and nonassessable and none of such
capital stock constitutes Margin Stock. Each of the Subsidiaries of Company
identified in Schedule 4.1 annexed hereto (as so supplemented) is a corporation
duly organized, validly existing and in good standing under the laws of its
respective jurisdiction of incorporation set forth therein, has all requisite
corporate power and authority to own and operate its properties and to carry on
its business as now conducted and as proposed to be conducted, and is qualified
to do business and in good standing in every jurisdiction where its assets are
located and wherever necessary to carry out its business and


                                      -63-
<PAGE>
operations, in each case except where failure to be so qualified or in good
standing or a lack of such corporate power and authority has not had and will
not have a Material Adverse Effect. Schedule 4.1 annexed hereto (as so
supplemented) correctly sets forth the ownership interest of Company and each of
its Subsidiaries in each of the Subsidiaries of Company identified therein.

         D. COLLATERAL DOCUMENTS. The security interests created in favor of
Administrative Agent under the Collateral Documents have at all times from and
after the Initial Closing Date constituted and will continue to constitute, as
security for the obligations purported to be secured thereby, a legal, valid and
enforceable security interest in and Lien on all of the Collateral referred to
therein in favor of Administrative Agent for the benefit of the Lenders,
perfected and prior to the rights of all third persons in accordance with the
requirements of all applicable Collateral Documents. Each Loan Party has good
and marketable title to its respective Collateral, and all such Collateral is
free and clear of all Liens except for Liens permitted by subsection 6.2. No
consents, filings or recordings are required in order to perfect (or maintain
the perfection or priority of) the security interests purported to be created by
any of the Collateral Documents, other than such as have been obtained and which
remain in full force and effect and UCC financing statements to be filed, or
delivered to Administrative Agent for filing, on the Fourth Restatement Date and
periodic UCC continuation filings or as is specifically otherwise permitted by
the terms of any applicable Collateral Document.

4.2      AUTHORIZATION OF BORROWING, ETC.

         A. AUTHORIZATION OF BORROWING. The execution, delivery and performance
of the Loan Documents have been duly authorized by all necessary corporate
action on the part of each Loan Party.

         B. NO CONFLICT. The execution, delivery and performance by the Loan
Parties of the Loan Documents and the consummation of the transactions
contemplated by the Loan Documents do not and will not (i) violate any provision
of any law or any governmental rule or regulation applicable to Company or any
of its Subsidiaries, the Certificate or Articles of Incorporation or Bylaws of
Company or any of its Subsidiaries or any order, judgment or decree of any court
or other agency of government binding on Company or any of its Subsidiaries,
(ii) conflict with in any material respect, result in a material breach of or
constitute (with due notice or lapse of time or both) a material default under
any Contractual Obligation of Company or any of its Subsidiaries, (iii) result
in or require the creation or imposition of any Lien upon any of the properties
or assets of Company or any of its Subsidiaries (other than any Liens created
under any of the Loan Documents in favor of Administrative Agent on behalf of
Lenders), or (iv) require any approval of stockholders or any approval or
consent of any Person under any Contractual Obligation of Company or any of its
Subsidiaries, except for such approvals or consents which will be obtained on or
before the Fourth Restatement Date and disclosed in writing to Lenders.


                                      -64-
<PAGE>
         C. GOVERNMENTAL CONSENTS. The execution, delivery and performance by
the Loan Parties of the Loan Documents and the consummation of the transactions
contemplated by the Loan Documents do not and will not require any registration
with, consent or approval of, or notice to, or other action to, with or by, any
federal, state or other governmental authority or regulatory body which has not
been obtained or made on or prior to the date required to be obtained or made
unless waived by Administrative Agent in accordance with this Agreement.

         D. BINDING OBLIGATION. Each of the Loan Documents has been duly
executed and delivered by each of the Loan Parties party thereto and is the
legally valid and binding obligation of each such Loan Party, enforceable
against such Loan Party in accordance with its respective terms, except as may
be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or limiting creditors' rights generally or by equitable principles
relating to enforceability.

4.3      FINANCIAL CONDITION.

         Company has heretofore delivered to Lenders, at Lenders' request, the
following financial statements and information: the audited consolidated balance
sheets of Company and its Subsidiaries as at December 31, 1999, and the related
consolidated statements of income, stockholders' equity and cash flows of
Company and its Subsidiaries for the Fiscal Year then ended. All such statements

franchises before any penalty, fine or interest accrues thereon, and all claims
(including, without limitation, claims for labor, services, materials and
supplies) for sums that have become due and payable and that by law have or may
become a Lien upon any of its properties or assets, prior to the time when any
penalty fine or interest shall be incurred with respect thereto; provided that
no such charge or claim need be paid if being contested in good faith by
appropriate proceedings promptly instituted and diligently conducted and if such
reserve or other appropriate provision, if any, with respect to any liability
for taxes, as shall be required in conformity with GAAP shall have been made
therefor in the financial statements of the Company.

cause to be maintained, with insurers of recognized responsibility and

customarily carried or maintained under similar circumstances by corporations
engaged in similar businesses and Company will, with respect to each Financed

         Company may self-insure, by way of deductible or equivalent structures
or provisions in insurance policies, the risks required to be insured against
pursuant to this subsection 5.4 in such reasonable amounts as are then
applicable to other similar aircraft or spare engines in Company's fleet, and as
are not substantially greater than amounts self-insured by corporations engaged
in the same or similar business and similarly situated with Company; provided,
however, that Company may not self-insure in an amount in excess of $1,000,000
per Financed Aircraft without the prior written consent of Administrative Agent.

financial and accounting records, and, with the permission of Company which
shall not be unreasonably withheld, to make copies and take extracts therefrom,
and to discuss its and their affairs, finances and accounts with its and their
officers and independent public accountants (provided that Company may, if it so
chooses, be present at or participate in any such discussion), all upon
reasonable notice and at such reasonable times during normal business hours and
as often as may be reasonably requested; provided that so long as no Event of
Default shall have occurred and be continuing, such inspection shall not be
disruptive to Company's business, as reasonably determined by Company. Within
120 days after the end of each Fiscal Year, senior management of Company shall

                                      -75-

5.6      COMPLIANCE WITH LAWS, ETC.

         Company will, and will cause its Subsidiaries to, comply with the
requirements of all applicable laws, rules, regulations and orders of any
governmental authority (including, without limitation, Environmental Laws),
noncompliance with which could reasonably be expected to cause a Material
Adverse Effect. Company shall not conduct, and shall not permit the conduct of,
any Hazardous Materials Activity at any Facility or at any other location which
could reasonably be expected to form the basis of an Environmental Claim against
Company and which could reasonably be expected to have a Material Adverse
Effect.

5.7      ENVIRONMENTAL INDEMNITY.

         Company agrees to indemnify, defend, and hold harmless Administrative
Agent and Lenders, and the officers, directors, employees, agents and affiliates
of Administrative Agent and Lenders from and against any and all losses, claims,
liability or expenses arising in connection with Environmental Claims against
Company or with any Hazardous Materials Activity.

5.8      COMPANY'S REMEDIAL ACTION REGARDING HAZARDOUS MATERIALS.

         Company will promptly take, and will cause each of its Subsidiaries
promptly to take, any and all necessary remedial action in connection with the
presence, storage, use, disposal, transportation or Release of any Hazardous
Materials on, under or about any Facility in order to comply with all applicable
Environmental Laws and Governmental Authorizations. In the event Company or any
of its Subsidiaries undertakes any remedial action with respect to any Hazardous
Materials on, under or about any Facility, Company or such Subsidiary will
conduct and complete such remedial action in compliance with all applicable
Environmental Laws, and in accordance with the policies, orders and directives
of all federal, state and local governmental authorities except when, and only
to the extent that, Company's or such Subsidiary's liability for such presence,
storage, use, disposal, transportation or discharge of any Hazardous Materials
is being contested in good faith by Company or such Subsidiary.

5.9      FURTHER ASSURANCES; NEW SUBSIDIARIES; HOLDING COMPANY.

         A. At any time or from time to time upon the request of Administrative
Agent, Company will, at its expense, promptly execute, acknowledge and deliver
such further documents and do such other acts and things as Administrative Agent
may reasonably request in order to effect fully the purposes of the Loan
Documents and to provide for payment of the Obligations in accordance with the
terms of this Agreement, the Notes and the other Loan Documents.

         B. In furtherance and not in limitation of the foregoing, Company will
cause any Subsidiary whose total assets exceed 15% of the consolidated total
assets of Company, in each case determined in accordance with GAAP (other than a
Special Purpose Subsidiary or


                                      -76-
<PAGE>
Atlas One), to take such actions as Administrative Agent may reasonably request
from time to time to ensure that the Obligations are guarantied by any such
Subsidiary. If, after the Fourth Restatement Date, Company or any of its
Subsidiaries (other than a Special Purpose Subsidiary or Atlas One) acquires any
asset, other than an aircraft financed with Loans hereunder or with Other
Permitted Indebtedness, with a fair market value in excess of $5 million, or the
value of spare parts of Company and its Subsidiaries not subject to Liens
securing Designated Indebtedness exceeds $25 million in the aggregate, Company
shall so notify Administrative Agent and take, or cause such Subsidiaries to
take, such actions as Administrative Agent may reasonably request from time to
time (including, without limitation, the execution and delivery of guaranties,
security agreements, mortgages, deeds of trust, financing statements and other
documents, the filing or recording of any of the foregoing, title insurance with
respect to any of the foregoing that relates to an interest in real property,
and the delivery of stock certificates and other collateral with respect to
which perfection is obtained by possession) to ensure that the Obligations are
secured by a first priority security interest in such asset or spare parts
(other than capital stock of a Subsidiary), as the case may be; provided that,
in the case of any engine otherwise subject to such security interest, such Lien
may be released at the request of Company in connection with a refinancing
thereof with Other Permitted Indebtedness. Notwithstanding the foregoing, so
long as the AFL III Financing remains outstanding nothing herein shall cause or
give rise to an obligation on the part of the Company or AFL III to require a
guaranty or grant of security interest in the assets of AFL III. The Lenders
acknowledge that the security interests and Liens created by the Collateral
Documents do not extend to the assets of AFL III now existing or hereafter
acquired.

         C. In furtherance and not in limitation of the foregoing, if Company
interposes a Holding Company, Company will cause the Holding Company to take
such actions (including, without limitation, the execution and delivery of a
guaranty, pledge agreement, financing statements and other documents, the filing
or recording of any of the foregoing, and the delivery of stock certificates
properly endorsed for transfer or accompanied by duly executed stock powers) as
Administrative Agent and Lenders may reasonably request to ensure that the
Obligations are guarantied by the Holding Company and that the Obligations are
secured by a first priority security interest in all of the capital stock of
Company. Company agrees that the Holding Company will not incur, directly or
indirectly, any Indebtedness and will not engage in any business or activity or
own any assets other than (1) holding the capital stock of Company or other
Subsidiaries formed by the Holding Company, and performing its obligations
incidental thereto, (2) employing certain management employees and pilots and
performing its obligations incidental thereto, (3) paying general administrative
costs and expenses in the ordinary course of business and (4) such other
activities as may be consented to from time to time by Requisite Lenders.

5.10     APPRAISALS.

         At the request of Administrative Agent or Requisite Lenders (but no
more than once


                                      -77-
<PAGE>
each calendar year), Company will obtain appraisals of each of the Financed
Aircraft from two Approved Appraisers, in form and substance satisfactory to
Administrative Agent; provided that, upon the occurrence and during the
continuance of an Event of Default, Company will obtain such additional
appraisals with respect to the Financed Aircraft as Administrative Agent or
Requisite Lenders may request.

5.11     MAINTENANCE CONTRACTS.

         Company shall maintain contracts with respect to the maintenance of
each Financed Aircraft sufficient to insure compliance with the Federal Aviation
Act, in form and substance reasonably satisfactory to Administrative Agent.

5.12     EMPLOYEE BENEFIT PLANS.

         Company will not establish or permit to be established any Employee
Benefit Plans for Company or any of its employees and will not permit any ERISA
Affiliate to establish any Employee Benefit Plan which, in either case, could
result in a liability for Company, under ERISA, in excess of $10 million.

5.13     REGISTRATION OF FOREIGN LEASED AIRCRAFT WITH FAA.

         Upon termination of an Approved Lease to which a Foreign Leased
Aircraft is subject, Company shall cause such Foreign Leased Aircraft to be
deregistered in such country and registered under the Federal Aviation Act and
file for recordation with the FAA following such deregistration a First Aircraft
Chattel Mortgage and Second Aircraft Chattel Mortgage with respect to such
Foreign Leased Aircraft and shall cause FAA counsel to deliver an opinion in
form and substance satisfactory to Administrative Agent.

5.14     CORPORATE SEPARATENESS.

         Following the creation of a Holding Company, Company will take all such
action as is necessary to keep its operations separate and apart from those of
Holding Company or any of its Affiliates, including, without limitation,
ensuring that all customary corporate formalities, including the maintenance of
separate corporate records and documents and holding regular meetings are
followed. Any financial statements distributed to any creditors of Company shall
clearly establish the corporate separateness of Company from Holding Company and
each Holding Company Subsidiary. Company shall not take any action or conduct
its affairs in a manner that is likely to result in the corporate existence of
Company on the one hand and of Holding Company or any Holding Company Subsidiary
on the other hand being disregarded, or in the assets and liabilities of Holding
Company or any Holding Company Subsidiary being substantively consolidated with
those of Company in a bankruptcy, reorganization or other insolvency proceeding.
Company shall maintain its principal executive office separate from Holding
Company or any of its Affiliates.

         associated with such Financed Aircraft;

         Indebtedness is to be incurred, (ii) the ratio of Consolidated Adjusted
         EBITDA for such four fiscal quarter period to Consolidated Interest

         outstanding in accordance with subsection 6.4(vi), $50 million at any
         time outstanding;

<PAGE>
by written notice to Company, may at their option rescind and annul such
acceleration and its consequences; but such action shall not affect any
subsequent Event of Default or Potential Event of Default or impair any right
consequent thereon. The provisions of this paragraph are intended merely to bind
Lenders to a decision which may be made at the election of Requisite Lenders and
are not intended to benefit Company and do not grant Company the right to
require Lenders to rescind or annul any acceleration hereunder, even if the
conditions set forth herein are met.

                                   SECTION 8.
                                      AGENT

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

8.2      POWERS AND DUTIES; GENERAL IMMUNITY.

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

         B. NO RESPONSIBILITY FOR CERTAIN MATTERS. Administrative Agent shall
not be responsible to any Lender for the execution, effectiveness, genuineness,
validity, enforceability, collectibility or sufficiency of this Agreement or any
other Loan Document or for any representations, warranties, recitals or
statements made herein or therein or made in


                                      -97-
<PAGE>
any written or oral statements or in any financial or other statements,
instruments, reports or certificates or any other documents furnished or made by
Administrative Agent to Lenders or by or on behalf of Company to Administrative
Agent or any Lender in connection with the Loan Documents and the transactions
contemplated thereby or for the financial condition or business affairs of
Company or any other Person liable for the payment of any Obligations, nor shall
Administrative Agent be required to ascertain or inquire as to the performance
or observance of any of the terms, conditions, provisions, covenants or
agreements contained in any of the Loan Documents or as to the use of the
proceeds of the Loans or as to the existence or possible existence of any Event
of Default or Potential Event of Default. Anything contained in this Agreement
to the contrary notwithstanding, Administrative Agent shall not have any
liability arising from confirmations of the amount of outstanding Loans or the
component amounts thereof.

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

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


                                      -98-
<PAGE>
financial advisory or other business with Company or any of its Affiliates as if
it were not performing the duties specified herein, and may accept fees and
other consideration from Company for services in connection with this Agreement
and otherwise without having to account for the same to Lenders.

8.3      REPRESENTATIONS AND WARRANTIES; NO RESPONSIBILITY FOR APPRAISAL OF
CREDITWORTHINESS.

         Each Lender represents and warrants that it has made its own
independent investigation of the financial condition and affairs of Company and
its Subsidiaries in connection with the making of the Loans hereunder and that
it has made and shall continue to make its own appraisal of the creditworthiness
of Company and its Subsidiaries. Administrative Agent shall have no duty or
responsibility, either initially or on a continuing basis, to make any such
investigation or any such appraisal on behalf of Lenders or to provide any
Lender with any credit or other information with respect thereto, whether coming
into its possession before the making of the Loans or at any time or times
thereafter, and Administrative Agent shall not have responsibility with respect
to the accuracy of or the completeness of any information provided to Lenders.

8.4      RIGHT TO INDEMNITY.

         Each Lender, in proportion to its Pro Rata Share, severally agrees to
indemnify Administrative Agent (and its respective affiliates and partners), to
the extent that Administrative Agent shall not have been reimbursed by Company,
for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including, without
limitation, counsel fees and disbursements) or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against
Administrative Agent in exercising its powers, rights and remedies or performing
its duties hereunder or under the other Loan Documents or otherwise in its
capacity as Administrative Agent, in any way relating to or arising out of this
Agreement or the other Loan Documents; provided that no Lender shall be liable
for any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from
Administrative Agent's gross negligence or willful misconduct.

8.5      COLLATERAL DOCUMENTS.

         Without limiting the generality of subsection 8.1, each Lender hereby
further authorizes Administrative Agent to enter into the Collateral Documents
as secured party on behalf of and for the benefit of such Lender and agrees to
be bound by the terms of each of the Collateral Documents; provided that, except
as otherwise provided below, Administrative Agent shall not enter into or
consent to any amendment, modification, termination or waiver of any provision
contained in any Collateral Document without prior written consent of Requisite
Lenders. Anything contained in any of the Loan Documents to the contrary
notwithstanding, each Lender agrees that no Lender shall have any right
individually to


                                      -99-
<PAGE>
realize upon any of the collateral under any Collateral Document, it being
understood and agreed that all powers, rights and remedies under the Collateral
Documents may be exercised solely by Administrative Agent for the benefit of
Lenders in accordance with the terms thereof. Each Lender hereby authorizes
Administrative Agent (i) to release or subordinate Collateral as permitted or
required under this Agreement or the Collateral Documents, and agrees that a
certificate executed by Administrative Agent evidencing such release of
Collateral shall be conclusive evidence of such release as to any third party
and (ii) to enter into any amendments of the Collateral Documents to cure any
ambiguity, defect or inconsistency or to amend provisions relating to
ministerial or administrative matters which do not materially adversely affect
the rights of the Lenders thereunder.

8.6      SUCCESSOR ADMINISTRATIVE AGENT.

         Administrative Agent may resign at any time by giving 30 days' prior
written notice thereof to Lenders and Company. Upon any such notice of
resignation, Requisite Lenders shall have the right, upon consultation with
Company, to appoint a successor Administrative Agent. Upon the acceptance of any
appointment hereunder by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent and
the retiring or removed Administrative Agent shall be discharged from its duties
and obligations under this Agreement. After any retiring Administrative Agent's
resignation hereunder as Administrative Agent, the provisions of this Section 8
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Administrative Agent under this Agreement.

         A. GENERAL. Each Lender shall have the right at any time to (i) sell,
assign or transfer to any Eligible Assignee, or (ii) sell participations to any
Person in, all or any part of its Commitments or any Loan or Loans made by it or
any other interest herein or in any other Obligations owed to it; provided that
no such sale, assignment, transfer or participation shall, without the consent
of Company, require Company to file a registration statement with the Securities
and Exchange Commission or apply to qualify such sale, assignment, transfer or
participation under the securities laws of any state; provided, further that no
such sale, assignment or transfer described in clause (i) above shall be
effective unless and until (a) an Assignment Agreement effecting such sale,
assignment or transfer shall have been accepted by Administrative Agent and
recorded in the Register as provided in subsection 9.1B(ii) or (b) the sale,
assignment or transfer is made in accordance with subsection 9.21. Except as
otherwise provided in this subsection 9.1, no Lender shall, as between Company
and such Lender, be relieved of any of its obligations hereunder as a result of
any sale, assignment or


                                     -100-
<PAGE>
transfer of, or any granting of participations in, all or any part of its
Commitments or the Loans, or the other Obligations owed to such Lender.

         B.       ASSIGNMENTS.

                  (i) Amounts and Terms of Assignments. Each Commitment, Loan or
         other Obligation may (a) be assigned in any amount to another Lender,
         or to an Affiliate of the assigning Lender or another Lender, with the
         giving of notice to Company and Administrative Agent or (b) be assigned
         in an aggregate amount of not less than $5,000,000 (or such lesser
         amount as shall constitute the aggregate amount of the Commitments,
         Loans, and other Obligations of the assigning Lender) to any other
         Eligible Assignee with the giving of notice to Company and with the
         consent of Administrative Agent and Company (which consent shall not be
         unreasonably withheld). Any assignment of Loans hereunder shall effect
         a pro rata assignment of the Notes with respect to each Financed
         Aircraft. To the extent of any such assignment in accordance with
         either clause (a) or (b) above, the assigning Lender shall be relieved
         of its obligations with respect to its Commitments, Loans, or other
         Obligations or the portion thereof so assigned. The parties to each
         such assignment shall execute and deliver to Administrative Agent, for
         its acceptance and recording in the Register, an Assignment Agreement,
         together with a processing and recordation fee of $3,000 and such
         forms, certificates or other evidence, if any, with respect to United
         States federal income tax withholding matters as the assignee under
         such Assignment Agreement may be required to deliver to Administrative
         Agent pursuant to subsection 2.7B(iii)(a); provided, however that such
         processing fee shall not be required where the assignee is an existing
         Lender. Upon such execution, delivery and acceptance, from and after
         the effective date specified in such Assignment Agreement, (y) the
         assignee thereunder shall be a party hereto and, to the extent that
         rights and obligations hereunder have been assigned to it pursuant to
         such Assignment Agreement, shall have the rights and obligations of a
         Lender hereunder and (z) the assigning Lender thereunder shall, to the
         extent that rights and obligations hereunder have been assigned by it
         pursuant to such Assignment Agreement, relinquish its rights and be
         released from its obligations under this Agreement (and, in the case of
         an Assignment Agreement covering all or the remaining portion of an
         assigning Lender's rights and obligations under this Agreement, such
         Lender shall cease to be a party hereto). The Commitments hereunder
         shall be modified to reflect the Commitment of such assignee and any
         remaining Commitment of such assigning Lender and, if any such
         assignment occurs after the issuance of the Notes hereunder, the
         assigning Lender shall, upon the effectiveness of such assignment or as
         promptly thereafter as practicable, surrender its applicable Notes to
         Administrative Agent for cancellation, and thereupon new Notes shall be
         issued to the assignee substantially in the form of Exhibit IIIA
         annexed hereto or Exhibit IIIB, as the case may be, with appropriate
         insertions, to reflect the new Commitments and/or outstanding Loans, as
         the case may be, of the assignee and/or the assigning Lender.

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

         C. PARTICIPATIONS. The holder of any participation, other than an
Affiliate of the Lender granting such participation, shall not be entitled to
require such Lender to take or omit to take any action hereunder except action
directly affecting (i) the extension of the scheduled final maturity date of any
Loan allocated to such participation, (ii) a reduction of the principal amount
of or the rate of interest payable on any Loan allocated to such participation
or (iii) a release of Collateral, and all amounts payable by Company hereunder
(including without limitation amounts payable to such Lender pursuant to
subsections 2.6D and 2.7) shall be determined as if such Lender had not sold
such participation. Company and each Lender hereby acknowledge and agree that,
solely for purposes of subsection 9.5, (a) any participation will give rise to a
direct obligation of Company to the participant and (b) the participant shall be
considered to be a "Lender".

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

         E. INFORMATION. Each Lender may furnish any information concerning
Company and its Subsidiaries in the possession of that Lender from time to time
to assignees and participants (including prospective assignees and
participants), subject to subsection 9.19.


                                     -102-

9.2      EXPENSES.

         Whether or not the transactions contemplated hereby shall be
consummated, Company agrees to pay promptly (i) all the actual and reasonable
costs and expenses of preparation of the Loan Documents; (ii) all the costs of
furnishing all opinions by counsel for Company (including without limitation any
opinions requested by Lenders as to any legal matters arising hereunder) and of
Company's performance of and compliance with all agreements and conditions on
its part to be performed or complied with under this Agreement and the other
Loan Documents including, without limitation, with respect to confirming
compliance with environmental and insurance requirements; (iii) the reasonable
fees, expenses and disbursements of counsel to Administrative Agent in
connection with the negotiation, preparation, execution and administration of
the Loan Documents and the Loans and any consents, amendments, waivers or other
modifications hereto or thereto and any other documents or matters requested by
Company; (iv) all the costs and expenses of creating and perfecting the Liens in
favor of Administrative Agent for the benefit of Lenders pursuant to the Loan
Documents, including filing and recording fees and expenses, title insurance,
fees and expenses of counsel for providing such opinions as Lenders may
reasonably request and fees and expenses of legal counsel to Administrative
Agent (including local counsel); (v) all other actual and reasonable costs and
expenses incurred by Administrative Agent in connection with the syndication of
the Commitments and the negotiation, preparation and execution of the Loan
Documents and the transactions contemplated hereby and thereby; provided that
such costs and expenses of syndication shall not exceed $10,000; and (vi) after
the occurrence of an Event of Default, all costs and expenses, including
reasonable attorneys' fees (including allocated costs of internal counsel) and
costs of settlement, incurred by Administrative Agent and Lenders in enforcing
any Obligations of or in collecting any payments due from Company hereunder or
under the other Loan Documents by reason of such Event of Default or in
connection with any refinancing or restructuring of the credit arrangements
provided under this Agreement in the nature of a "work-out" or pursuant to any
insolvency or bankruptcy proceedings.

9.3      INDEMNITY.

         In addition to the payment of expenses pursuant to subsection 9.2,
whether or not the transactions contemplated hereby shall be consummated,
Company agrees to defend, indemnify, pay and hold harmless Administrative Agent
and Lenders, and the officers, directors, partners, employees, agents and
affiliates of Administrative Agent and Lenders (collectively called the
"INDEMNITIES") from and against any and all other liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs, expenses
and disbursements of any kind or nature whatsoever (including without limitation
the reasonable fees and disbursements of counsel for such Indemnities in
connection with any investigative, administrative or judicial proceeding
commenced or threatened by any Person, whether or not any such Indemnitee shall
be designated as a party or a potential party thereto), whether direct, indirect
or consequential and whether based on any federal, state or foreign laws,


                                     -103-
<PAGE>
statutes, rules or regulations (including without limitation securities and
commercial laws, statutes, rules or regulations and Environmental Laws), on
common law or equitable cause or on contract or otherwise, that may be imposed
on, incurred by, or asserted against any such Indemnitee, in any manner relating
to or arising out of this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby (including without limitation
Lenders' agreement to make the Loans hereunder or the use or intended use of the
proceeds of any of the Loans) or the statements contained in the commitment
letter delivered by any Lender to Company with respect thereto (collectively
called the "INDEMNIFIED LIABILITIES"); provided that Company shall not have any
obligation to any Indemnitee hereunder with respect to any Indemnified
Liabilities to the extent such Indemnified Liabilities arise solely from the
gross negligence or willful misconduct of that Indemnitee as determined by a
final judgment of a court of competent jurisdiction. To the extent that the
undertaking to defend, indemnify, pay and hold harmless set forth in the
preceding sentence may be unenforceable because it is violative of any law or
public policy, Company shall contribute the maximum portion that it is permitted
to pay and satisfy under applicable law to the payment and satisfaction of all
Indemnified Liabilities incurred by the Indemnities or any of them.

9.4      SET-OFF.

         In addition to any rights now or hereafter granted under applicable law
and not by way of limitation of any such rights, upon the occurrence of any
Event of Default each Lender is hereby authorized by Company at any time or from
time to time, without notice to Company or to any other Person, any such notice
being hereby expressly waived, to set off and to appropriate and to apply any
and all deposits (general or special, including, but not limited to,
Indebtedness evidenced by certificates of deposit, whether matured or unmatured,
but not including trust accounts) and any other Indebtedness at any time held or
owing by that Lender to or for the credit or the account of Company against and
on account of the obligations and liabilities of Company to that Lender under
this Agreement, the Notes, and the other Loan Documents, including, but not
limited to, all claims of any nature or description arising out of or connected
with this Agreement, the Notes, or any other Loan Document, irrespective of
whether or not (i) that Lender shall have made any demand hereunder or (ii) the
principal of or the interest on the Loans or any other amounts due hereunder
shall have become due and payable pursuant to Section 7 and although said
obligations and liabilities, or any of them, may be contingent or unmatured.

9.5      RATABLE SHARING.

         Lenders hereby agree among themselves that if any of them shall,
whether by voluntary payment, by realization upon security, through the exercise
of any right of set-off or banker's lien, by counterclaim or cross action or by
the enforcement of any right under the Loan Documents or otherwise, or as
adequate protection of a deposit treated as cash collateral under the Bankruptcy
Code, receive payment or reduction of a proportion of the aggregate amount of
principal, interest, fees and other amounts then due and owing to that Lender


                                     -104-
<PAGE>
hereunder or under the other Loan Documents (collectively, the "AGGREGATE
AMOUNTS DUE" to such Lender) which is greater than the proportion received by
any other Lender in respect of the Aggregate Amounts Due to such other Lender,
then the Lender receiving such proportionately greater payment shall (i) notify
Administrative Agent and each other Lender of the receipt of such payment and
(ii) apply a portion of such payment to purchase participations (which it shall
be deemed to have purchased from each seller of a participation simultaneously
upon the receipt by such seller of its portion of such payment) in the Aggregate
Amounts Due to the other Lenders so that all such recoveries of Aggregate
Amounts Due shall be shared by all Lenders in proportion to the Aggregate
Amounts Due to them; provided that if all or part of such proportionately
greater payment received by such purchasing Lender is thereafter recovered from
such Lender upon the bankruptcy or reorganization of Company or otherwise, those
purchases shall be rescinded and the purchase prices paid for such
participations shall be returned to such purchasing Lender ratably to the extent
of such recovery, but without interest. Company expressly consents to the
foregoing arrangement and agrees that any holder of a participation so purchased
may exercise any and all rights of banker's lien, set-off or counterclaim with
respect to any and all monies owing by Company to that holder with respect
thereto as fully as if that holder were owed the amount of the participation
held by that holder.

9.6      AMENDMENTS AND WAIVERS.

         A. No amendment, modification, termination or waiver of any provision
of this Agreement or of the Notes, or consent to any departure by Company
therefrom, shall in any event be effective without the written concurrence of
Requisite Lenders; provided that any such amendment, modification, termination,
waiver or consent which: increases the amount of any of the Commitments or
reduces the principal amount of any of the Loans; changes any Lender's Pro Rata
Share; changes in any manner the definition of "Requisite Lenders"; changes in
any manner any provision of this Agreement which, by its terms, expressly
requires the approval or concurrence of all Lenders; postpones the Final
Scheduled Maturity Date (but not the date of any scheduled installment of
principal) of any of the Loans; postpones the date on which any interest or any
fees are payable; decreases the interest rate borne by any of the Loans (other

Loans pursuant to subsection 2.2E) or the amount of any fees payable hereunder;
increases the maximum duration of Interest Periods permitted hereunder; releases
all or substantially all of the Collateral; or changes in any manner the
provisions contained in subsection 7.1 or this subsection 9.6 shall be effective
only if evidenced by a writing signed by or on behalf of all Lenders to whom are
owed Obligations being directly affected by such amendment, modification,
termination, waiver or consent. In addition, (i) any amendment, modification,
termination or waiver of any of the provisions contained in Section 3 shall be
effective only if evidenced by a writing signed by or on behalf of
Administrative Agent and Requisite Lenders, (ii) no amendment, modification,
termination or waiver of any provision of any Note shall be effective without
the written concurrence of the Lender which is the holder of that Note, (iii) no
increase in the Commitments of any Lender over the amount thereof then


                                     -105-
<PAGE>
in effect shall be effective without the written concurrence of that Lender, it
being understood and agreed that in no event shall waivers or modifications of
conditions precedent, covenants, Events of Default, Potential Events of Default
or of a mandatory prepayment or a reduction of any or all of the Commitments be
deemed to constitute an increase of the Commitment of any Lender and that an
increase in the available portion of any Commitment of any Lender shall not be
deemed to constitute an increase in the Commitment of such Lender, and (iv) no
amendment, modification, termination or waiver of any provision of Section 7 or
of any other provision of this Agreement which, by its terms, expressly requires
the approval or concurrence of Administrative Agent shall be effective without
the written concurrence of Administrative Agent. Administrative Agent may, but
shall have no obligation to, with the concurrence of any Lender, execute
amendments, modifications, waivers or consents on behalf of that Lender. Any
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which it was given. No notice to or demand on Company in
any case shall entitle Company to any other or further notice or demand in
similar or other circumstances. Any amendment, modification, termination, waiver
or consent effected in accordance with this subsection 9.6 shall be binding upon
each Lender at the time outstanding, each future Lender and, if signed by
Company, on Company. Notwithstanding anything in this subsection 9.6A to the
contrary, the Notes and Aircraft Chattel Mortgages may be amended in the manner
and for the purposes set forth in subsection 9.21 without the consents required
by this subsection 9.6A.

         B. If, in connection with any proposed change, waiver, discharge or
termination to any of the provision of this Agreement as contemplated by the
proviso in the first sentence of this subsection 9.6, the consent of Requisite
Lenders is obtained but consent of one or more of such other Lenders whose
consent is required is not obtained, then Company may, so long as all
non-consenting Lenders are so treated, elect to terminate such Lender as a party
to this Agreement; provided that, concurrently with such termination, (i)
Company shall pay that Lender all principal, interest and fees and other amounts
owed to such Lender through such date of termination, (ii) another financial
institution satisfactory to Company and Administrative Agent (or if
Administrative Agent is also the Lender to be terminated, the successor
Administrative Agent) shall agree, as of such date, to become a Lender for all
purposes under this Agreement (whether by assignment or amendment) and to assume
all obligations of the Lender to be terminated as of such date, and (iii) all
documents and supporting materials necessary, in the judgment of Administrative
Agent (or if Administrative Agent is also the Lender to be terminated, the
successor Administrative Agent) to evidence the substitution of such Lender
shall have been received and approved by Administrative Agent as of such date.

9.7      INDEPENDENCE OF COVENANTS.

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


                                     -106-
<PAGE>
covenant shall not avoid the occurrence of an Event of Default or Potential
Event of Default if such action is taken or condition exists.

9.8      NOTICES.

         Unless otherwise specifically provided herein, any notice or other
communication herein required or permitted to be given shall be in writing and
may be personally served, telexed or sent by telefacsimile or United States mail
or courier service and shall be deemed to have been given when delivered in
person or by courier service, upon receipt of telefacsimile or telex, or three
Business Days after depositing it in the United States mail with postage prepaid
and properly addressed; provided that notices to Administrative Agent shall not
be effective until received. For the purposes hereof, the address of each party
hereto shall be as set forth under such party's name on the signature pages
hereof or (i) as to Company and Administrative Agent, such other address as
shall be designated by such Person in a written notice delivered to the other
parties hereto and (ii) as to each other party, such other address as shall be
designated by such party in a written notice delivered to Administrative Agent.

9.9      SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

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

         B. Notwithstanding anything in this Agreement or implied by law to the
contrary, the agreements of Company set forth in subsections 2.6D, 2.7, 9.2, 9.3
and 9.4 and the agreements of Lenders set forth in subsections 8.2C, 8.4 and 9.5
shall survive the payment of the Loans, and the termination of this Agreement.

9.10     FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of Administrative Agent or any Lender
in the exercise of any power, right or privilege hereunder or under any other
Loan Document shall impair such power, right or privilege or be construed to be
a waiver of any default or acquiescence therein, nor shall any single or partial
exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other power, right or privilege. All rights and
remedies existing under this Agreement and the other Loan Documents are
cumulative to, and not exclusive of, any rights or remedies otherwise available.

9.11     MARSHALLING; PAYMENTS SET ASIDE.

         Neither Administrative Agent nor any Lender shall be under any
obligation to marshal any assets in favor of Company or any other party or
against or in payment of any or all of the Obligations. To the extent that
Company makes a payment or payments to Administrative Agent or Lenders (or to
Administrative Agent for the benefit of Lenders), or Administrative Agent or
Lenders enforce any security interests or exercise their rights of set-off, and
such


                                     -107-
<PAGE>
payment or payments or the proceeds of such enforcement or set-off or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside and/or required to be repaid to a trustee, receiver or any other party
under any bankruptcy law, any other state or federal law, common law or any
equitable cause, then, to the extent of such recovery, the obligation or part
thereof originally intended to be satisfied, and all Liens, rights and remedies
therefor or related thereto, shall be revived and continued in full force and
effect as if such payment or payments had not been made or such enforcement or
set-off had not occurred.

9.12     SEVERABILITY.

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

9.13     OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS' RIGHTS.

         The obligations of Lenders hereunder are several and no Lender shall be
responsible for the obligations or Commitments of any other Lender hereunder.
Nothing contained herein or in any other Loan Document, and no action taken by
Lenders pursuant hereto or thereto, shall be deemed to constitute Lenders as a
partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt, and each Lender shall be entitled to protect and enforce its
rights arising out of this Agreement and it shall not be necessary for any other
Lender to be joined as an additional party in any proceeding for such purpose.

respective successors and assigns and shall inure to the benefit of the parties
hereto and the successors and assigns of Lenders (it being understood that
Lenders' rights of assignment are subject to


                                     -108-
<PAGE>
subsection 9.1). Neither Company's rights or obligations hereunder nor any
interest therein may be assigned or delegated by Company without the prior
written consent of all Lenders.

9.17     CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY OBLIGATION MAY BE
BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE OF

any bona fide assignee, transferee or participant in connection with the
contemplated assignment or transfer by such Lender of any Loans or any
participation therein or as required or requested by any governmental or
regulatory agency (including, without limitation, the National Association of
Insurance Commissioners) or representative thereof or pursuant to legal process
or in accordance with any applicable law or regulation; provided that, unless
specifically prohibited by applicable law or court order, each Lender shall
notify Company of any request by any governmental or regulatory agency or
representative thereof (other than any such request in connection with any
examination of the financial condition of such Lender by such governmental or
regulatory agency) for disclosure of any such non-public information prior to
disclosure of such information; and provided, further that in no event shall any
Lender be obligated or required to return any materials furnished by Company or

9.20     COUNTERPARTS; EFFECTIVENESS; EFFECT IF AGREEMENT DOES NOT BECOME
         EFFECTIVE.

         This Agreement and any amendments, waivers, consents or supplements
hereto or in connection herewith may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document. This Agreement shall become effective upon the execution of a
counterpart hereof by each of the parties hereto and receipt by Company and
Administrative Agent of written or telephonic notification of such execution and
authorization of delivery thereof and the satisfaction (or waiver) of each of
the conditions set forth in subsection 3.1. Until this Agreement becomes

execution and delivery of this Agreement shall be disregarded and this Agreement
shall be deemed null


                                     -110-

and void for all purposes.

9.21     COOPERATION IN REFINANCING, SYNDICATION AND ASSIGNMENT.

         Company, Administrative Agent and Lenders agree that, in connection
with the refinancing, syndication or assignment of the Notes, to the extent
deemed reasonably necessary by Company or Administrative Agent, some or all of
the Financed Aircraft may be transferred to a Special Purpose Subsidiary which
will lease such aircraft to Company under arrangements reasonably acceptable to
Company and Administrative Agent all in a manner designed to retain the economic
obligations and benefits of the Company, Administrative Agent and Lenders
hereunder and under the other Loan Documents. Company, Administrative Agent and
Lenders further agree that, in connection with an assignment of Loans and Notes
to a Person who will not become a Lender hereunder, Administrative Agent and
Lenders shall agree to any amendments to the Loans and Notes to be assigned and
the related Aircraft Chattel Mortgages and/or releases of the related First
Aircraft Chattel Mortgage and Second Aircraft Chattel Mortgage, in each case, as
requested by Company; provided that the terms of such amended Notes and Aircraft
Chattel Mortgages do not violate any term of this Agreement and provided,
further, that such amendments shall be effective only upon and simultaneous with
(i) the assignment of such Notes and Aircraft Chattel Mortgages to such Person,
(ii) indefeasible payment in full to Lenders of an amount equal to all amounts
owing under such Notes and (iii) releases from any liability relating to such
Notes and Aircraft Chattel Mortgages of Administrative Agent and Lenders in form
and substance satisfactory to Administrative Agent. Assignments made in
accordance with the foregoing sentence will result in such assigned Loans and
Notes being deemed not "outstanding" hereunder and such assigned Loans and Notes
will not reduce the Revolving Loan Commitments of the Lenders otherwise
available hereunder.

9.22     REPLACEMENT ENGINES.

         A. ENGINES. So long as no Event of Default or Potential Event of
Default has occurred and is continuing, Company may, upon not less than five (5)
Business Days prior written notice to Administrative Agent, replace any Engine
which is the subject of an Aircraft Chattel Mortgage with another engine (the
"Replacement Engine") meeting the requirements of the applicable Aircraft
Chattel Mortgage. In addition to the preceding sentence, any Replacement Engine
shall be an engine that is the same or improved make and model as the Engine to
be replaced, and that is suitable for installation and use on any Airframe, and
that has a value, utility and remaining useful life (including with respect to
hours and cycles remaining until overhaul) at least equal to the Engine to be
replaced thereby.

                  The Lenders agree to release the Lien created by the
applicable Aircraft Chattel Mortgage for any Engine to be replaced by a
Replacement Engine promptly upon (i) presentation by Company of documentation
necessary to create a legal, valid and enforceable first priority security
interest in and to the Replacement Engine, (ii) delivery to Administrative


                                     -111-
<PAGE>
Agent of an opinion of Cahill Gordon & Reindel, or such other counsel as may be
acceptable to Administrative Agent, confirming that Administrative Agent will
continue to be entitled to the benefits of Section 1110 of the Bankruptcy Code
with respect to such Replacement Engine free of all Liens (other than Permitted
Encumbrances) and (iii) receipt of all other deliveries required by Section
4(f)(iii) of the applicable Aircraft Chattel Mortgage.

         B. Further Assurances. Company shall, in addition to the actions
required by the preceding subsection 9.21 A, take all necessary actions to
provide that Administrative Agent will continue to be entitled to the benefits
of Section 1110 of the Bankruptcy Code with respect to each Replacement Engine,
free of all Liens (other than Permitted Encumbrances).

Administrative Agent telephonic notice by the required time of any proposed
borrowing under this subsection 2.1B, provided that such notice is promptly
confirmed in writing.

        (ii)      Neither the Administrative Agent nor any Lender shall incur
any liability to the Borrower in acting upon any telephonic notice referred to
above that the Administrative Agent believes in good faith to have been given
by a duly authorized officer or other person authorized to borrow on behalf of
the Borrower or for otherwise acting in good faith under this subsection 2.1B,
and upon funding of the Loans by the Lenders in accordance with this Agreement
pursuant to any such telephonic notice the Borrower shall have effected the

                                      -22-

<PAGE>

Loans hereunder. The Borrower shall notify the Administrative Agent prior to
the funding of the Loans in the event that any of the matters to which the
Borrower is required to certify in the Notice of Borrowing is no longer true
and correct as of the Initial Borrowing Date and the acceptance by the Borrower
of the proceeds of any Loans shall constitute a recertification by the Borrower
as of the Initial Borrowing Date, as to the matters to which the Borrower is
required to certify in the applicable Notice of Borrowing.

         C.       DISBURSEMENT OF FUNDS. All Loans under this Agreement shall
be made by the Lenders simultaneously and proportionately to their respective
Pro Rata Shares, it being understood that no Lender shall be responsible for
any default by any other Lender in that other Lender's obligation to make a
Loan requested hereunder nor shall the Commitment of any Lender to make a Loan
requested be increased or decreased as a result of a default by any other
Lender in that other Lender's obligation to make a Loan requested hereunder.
Promptly after receipt by the Administrative Agent of a Notice of Borrowing
pursuant to subsection 2.1B (or telephonic notice in lieu thereof), the
Administrative Agent shall notify each Lender of the proposed borrowing. Each
Lender shall make the amount of its Loans available to the Administrative Agent
not later than 12:00 Noon (New York time) on the Initial Borrowing Date, in
each case in same day funds in Dollars, at the Funding and Payment Office.

         Unless the Administrative Agent shall have been notified by any Lender
prior to the Initial Borrowing Date that such Lender does not intend to make
available to the Administrative Agent the amount of such Lender's Loans so
requested on the Initial Borrowing Date, the Administrative Agent may assume
that such Lender has made such amount available to the Administrative Agent on
the Initial Borrowing Date and the Administrative Agent may, in its sole
discretion, but shall not be obligated to, make available to the Borrower a
corresponding amount on the Initial Borrowing Date. If such corresponding
amount is not in fact made available to the Administrative Agent by such
Lender, the Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender together with interest thereon,
for each day from the Initial Borrowing Date until the date such amount is paid
to the Administrative Agent, at the customary rate set by the Administrative
Agent for the correction of errors among banks for three Business Days. If such
Lender does not pay such corresponding amount forthwith upon the Administrative
Agent's demand therefor, the Administrative Agent shall promptly notify the
Borrower and the Borrower shall immediately pay such corresponding amount to
the Administrative Agent together with interest thereon, for each day from the
Initial Borrowing Date until the date such amount is paid to the Administrative
Agent, at the rate payable under this Agreement. Nothing in this subsection
2.1C shall be deemed to relieve any Lender from its obligation to fulfill its
Commitment hereunder or to prejudice any rights that the Borrower may have
against any Lender as a result of any default by such Lender hereunder.

         D.       NOTES. (i) The Borrower shall duly execute and deliver on the
Initial Borrowing Date to each Tranche A Lender (or to the Administrative Agent
for that Tranche A

                                      -23-


<PAGE>

Lender) the Tranche A Notes, each substantially in the form of Exhibit IIA
annexed hereto, to evidence that Tranche A Lender's Tranche A Loans in respect
of each Aircraft or Spare Engine Pool, in the principal amount of such Tranche
A Lender's Tranche A Pro Rata Share of the Maximum Tranche A Loan Amount
relating to such Aircraft or Spare Engine Pool and with other appropriate
insertions (each a "TRANCHE A NOTE" and collectively, the "TRANCHE A NOTES").

         (ii)     The Borrower shall duly execute and deliver on the Initial
Borrowing Date to each Tranche B Lender (or to the Administrative Agent for
that Tranche B Lender) the Tranche B Notes, each substantially in the form of
Exhibit IIB annexed hereto, to evidence that Tranche B Lender's Tranche B Loans
in respect of each Aircraft or Spare Engine Pool, in the principal amount of
such Tranche B Lender's Tranche B Pro Rata Share of the Maximum Tranche B Loan
Amount relating to such Aircraft or Spare Engine Pool and with other
appropriate insertions (each a "TRANCHE B NOTE" and collectively, the "TRANCHE
B NOTES" and, together with the Tranche A Notes, the "NOTES").

         E.       THE REGISTER. (i) The Administrative Agent shall maintain, at
its address referred to in subsection 9.8, a register (the "REGISTER") for the
recordation of the names and addresses of the Lenders and the Commitments and
Loans of each Lender from time to time and the Administrative Agent shall
record in the Register the Commitments and the Loans from time to time of each
Lender and each repayment or prepayment in respect of the principal amount of
the Loans of each Lender. Such recordation shall be conclusive and binding on
the Borrower and each Lender, absent manifest error; provided, that failure to
make any such recordation, or any error in such recordation, shall not affect
the Borrower's Obligations in respect of the applicable Loans. The Register
shall be available for inspection by the Borrower or by any Lender at any
reasonable time and from time to time upon reasonable prior notice.

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

        (iii)     The Borrower, the Administrative Agent and the Lenders shall
deem and treat the Persons listed as Lenders in the Register as the holders and
owners of the corresponding Commitments and Loans listed therein for all
purposes hereof, and no assignment or transfer of any such Loan or Commitment
shall be effective in any case unless and until an Assignment Agreement
effecting the assignment or transfer thereof shall have been accepted by the
Administrative Agent and recorded in the Register as provided in subsection
9.1B(ii). Prior to such recordation, all amounts owed with respect to the
applicable Loan shall be owed

                                      -24-

<PAGE>

to the Lender listed in the Register as the owner thereof, and any request,
authority or consent of any Person who, at the time of making such request or
giving such authority or consent, is listed in the Register as a Lender shall
be conclusive and binding on any subsequent holder, assignee or transferee of
the corresponding Commitments or Loans.

         (iv)     The Borrower hereby designates the Administrative Agent to
serve as the Borrower's agent solely for purposes of maintaining the Register
as provided in this subsection 2.1E, and the Borrower hereby agrees that, to
the extent that the Administrative Agent serves in such capacity, the
Administrative Agent and its officers, directors, employees, agents and
affiliates shall constitute Indemnitees for all purposes under subsection 9.3.

2.2  INTEREST ON THE LOANS.

         A.       RATE OF INTEREST. (i) Subject to the provisions of Sections
2.6 and 2.7, each Loan shall bear interest on the unpaid principal amount
thereof from the Initial Borrowing Date through maturity (whether by
acceleration or otherwise) at a rate determined by reference to the Adjusted
Eurodollar Rate. The applicable Interest Period for determining the rate of
interest with respect to the Loans shall be determined in accordance with
subsection 2.2B.

         (ii)     Subject to the provisions of subsections 2.2D and 2.7, the
Loans shall bear interest through maturity at a per annum rate equal to the sum
of the Adjusted Eurodollar Rate plus the Applicable Margin.

        (iii)     The "TRANCHE A APPLICABLE MARGIN" for each Tranche A Loan
shall be 1.75% less the Pricing Reduction, if any, in effect from time to time.
The "TRANCHE B APPLICABLE MARGIN" for each Tranche B Loan shall be 2.00%.

         B.       INTEREST PERIODS. In connection with each Loan, the interest
period ("Interest Period") to be applicable to such Loan shall be three months;
provided, that:

         (i)      prior to the earlier of July 25, 2000, and the Syndication
     Date, the Interest Period for each Loan shall be one month, and the first
     such Interest Period shall commence on the Initial Borrowing Date;

        (ii)      each successive Interest Period shall be three months and
     shall commence on the day on which the next preceding Interest Period
     expires;

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

                                      -25-

<PAGE>


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

         (v)      no Interest Period shall extend beyond the Final Maturity
     Date for the applicable tranche of Loans;

        (vi)      no Interest Period shall extend beyond a date on which the
     Borrower is required to make a scheduled payment of principal of the Loans
     of the same tranche as such Loan; and

       (vii)      there shall be no more than one Interest Period at any time.

         C.       INTEREST PAYMENTS. Subject to the provisions of subsection
2.2D, interest on each Loan shall be payable in arrears on the last day of each
Interest Period applicable to that Loan, upon any prepayment of Loans (to the
extent accrued on the amount being prepaid) and at maturity (including final
maturity).

         D.       DEFAULT RATE. Upon the occurrence and during the continuation
of any Event of Default, the outstanding principal amount of all Loans and, to
the extent permitted by applicable law, any interest payments thereon not paid
when due and any fees and other amounts then due and payable hereunder, shall
thereafter bear interest (including post-petition interest in any proceeding
under the Bankruptcy Code or other applicable bankruptcy laws) payable upon
demand at a rate that is 2% per annum in excess of the interest rate otherwise
payable under this Agreement with respect to the applicable Loans (or, in the
case of any such fees and other amounts, at a rate that is 1% per annum in
excess of the sum of the Base Rate as in effect from time to time and the
Applicable Margin); provided, that, upon the expiration of the Interest Period
in effect at the time any such increase in interest rate is effective, such
Loans shall thereupon bear interest payable upon demand at a rate that is 1%
per annum in excess of the sum of the Base Rate as in effect from time to time
and the Applicable Margin. Payment or acceptance of the increased rates of
interest provided for in this subsection 2.2D is not a permitted alternative to
timely payment and shall not constitute a waiver of any Event of Default or
otherwise prejudice or limit any rights or remedies of the Administrative Agent
or any Lender.

         E.       COMPUTATION OF INTEREST. Interest on each Loan shall be
computed on the basis of a 360-day year, in each case for the actual number of
days elapsed in the period during which it accrues. In computing interest on
any Loan, the date of the making of such Loan or the first day of an Interest
Period applicable to such Loan shall be included, and the date of payment of
such Loan or the expiration date of an Interest Period applicable to such Loan
shall be excluded; provided, that if a Loan is repaid on the same day on which
it is made, one day's interest shall be paid on that Loan.

         C.       PREPAYMENTS.

         (i)      Voluntary Prepayments. The Borrower may, upon not less than
three Business Days' prior written or telephonic notice given to the
Administrative Agent by 12:00 Noon (New York time) on the date required, and,
if given by telephone, promptly confirmed in writing to the Administrative
Agent (which original written or telephonic notice the Administrative Agent
will promptly transmit by telefacsimile or telephone to each Lender), at any
time and from time to time prepay, without premium or penalty, the Loans on any
Business Day in whole or in part in an aggregate minimum amount of $5,000,000
and integral multiples of $500,000 in excess of that amount; provided, however,
that Loans may only be prepaid on the expiration of the Interest Period
applicable thereto. Notice of prepayment having been given as aforesaid, the
principal amount of the Loans specified in such notice shall become due and
payable on the prepayment date specified therein. Any such voluntary prepayment
shall be applied as specified in subsection 2.4C(iii).

        (ii)      Mandatory Prepayments.

         (a)      Prepayments and Reductions from Asset Sales. No later than
the second Business Day following the date of receipt by the Borrower of Cash
Proceeds of any Asset Sale, the Borrower shall prepay, without premium or
penalty (other than pursuant to subsection 2.6D), Loans in an amount equal to
the Net Cash Proceeds of such Asset Sale. Concurrently with any prepayment of
the Loans pursuant to this subsection 2.4C(ii)(a), the Borrower shall deliver
to the Administrative Agent an Officers' Certificate demonstrating the
derivation of the Net Cash Proceeds of the correlative Asset Sale from the
gross sales price thereof. In the event that the Borrower shall, at any time
after receipt of Cash Proceeds of any Asset Sale requiring a prepayment
pursuant to this subsection 2.4C(ii)(a), determine that the

                                      -28-

<PAGE>

prepayments previously made in respect of such Asset Sale were in an aggregate
amount less than that required by the terms of this subsection 2.4C(ii)(a), the
Borrower shall promptly make an additional prepayment of the Loans, as the case
may be, in the manner described above in an amount equal to the amount of any
such deficit, and the Borrower shall concurrently therewith deliver to the
Administrative Agent an Officers' Certificate demonstrating the derivation of
the additional Net Cash Proceeds resulting in such deficit. Any mandatory
prepayments pursuant to this subsection 2.4C(ii)(a) shall be applied as
specified in subsection 2.4C(iii).

         (b)      Prepayments and Reductions Due to Insurance and Condemnation
Proceeds. Within 270 days of receipt by the Borrower of any cash payments under
any of the casualty insurance policies covering damage to or loss of property
maintained pursuant to subsection 5.4 or otherwise resulting from damage to or
loss of all or any portion of the Collateral or any other tangible asset (net of
actual and documented reasonable costs incurred by the Borrower in connection
with adjustment and settlement thereof and in connection with the reinvestment
of proceeds permitted hereby, "INSURANCE PROCEEDS") or any proceeds resulting
from the taking of assets by the power of eminent domain, condemnation or
otherwise (net of actual and documented reasonable costs incurred by Borrower in
connection with adjustment and settlement thereof and in connection with the
reinvestment of proceeds permitted hereby, "CONDEMNATION PROCEEDS," and
collectively with Insurance Proceeds, "PROCEEDS") (other than proceeds applied
pursuant to subsection 2.4C(ii)(c)) and so long as at the time of receipt of
such proceeds there shall exist no Potential Event of Default or Event of
Default, the Borrower may reinvest such Proceeds in property substantially
similar to the property so damaged or lost so long as the Administrative Agent
receives a first priority perfected security interest in such property pursuant
to documentation acceptable to the Administrative Agent, the property is duly
leased to Atlas pursuant to the applicable Lease and the Administrative Agent
receives all documents and opinions in connection therewith that it may
reasonably request, including, without limitation, an opinion from counsel that
the Borrower as lessor and the Administrative Agent as the assignee under the
Lease are entitled to the benefits of Section 1110 of the Bankruptcy Code with
respect to such property. If, 270 days after receipt of any such Proceeds, the
Borrower has not reinvested such Proceeds as described above or if at the time
of receipt of such proceeds or at the time of reinvestment there shall exist a
Potential Event of Default or an Event of Default then the Borrower shall
immediately prepay, without premium or penalty (other than pursuant to
subsection 2.6D), those Loans relating to the Aircraft or Spare Engine Pool in
respect of which such Proceeds were received based on the outstanding principal
amount of each Loan as compared to the total outstanding principal amount of all
Loans relating to such Aircraft or Spare Engine Pool. Any amount of the Proceeds
remaining (a) after prepayment of the Loans described in the immediately
preceding sentence and/or (b) after being reinvested in the manner described in
the second preceding sentence shall be applied ratably to the prepayment of
Loans relating to all of the remaining Aircraft and Spare Engine Pools based on
the outstanding principal amount of each such Loan as compared to the total
outstanding principal amount of all Loans relating to all of the remaining
Aircraft and

                                      -29-

<PAGE>
Spare Engine Pools. Any such mandatory prepayments shall be applied as
specified in subsection 2.4C(iii). Until such time as such proceeds are
reinvested or applied to repay Loans, all such proceeds shall be held by the
Administrative Agent in a cash collateral account with the Administrative Agent
as security for the Obligations pursuant to a cash collateral agreement in form
and substance satisfactory to the Administrative Agent and providing that such
proceeds may be invested in Cash or Cash Equivalents at the direction of the
Borrower with any earnings thereon being for the account of the Borrower.

         (c)      Prepayments and Reductions Due to an Event of Loss. Following
an Event of Loss with respect to an Aircraft or a Spare Engine, the Borrower
shall prepay, without premium or penalty (other than pursuant to subsection
2.6(D)), the outstanding principal amount of Loans relating to the Aircraft or
Spare Engine Pool that were the subject of the Event of Loss; provided, that
the Borrower shall not be required to make a prepayment pursuant to this
subsection 2.4C(ii)(c) in the event that the Borrower receives Insurance
Proceeds or Condemnation Proceeds in connection with such Event of Loss so long
as at the time of reinvestment there exists no Potential Event of Default or
Event of Default, in which case such proceeds may, within 270 days of receipt
of any such Proceeds, be reinvested in aircraft or spare engines substantially
similar to the Aircraft or Spare Engines that were the subject of the Event of
Loss so long as such replacement aircraft or spare engines are duly leased to
Atlas pursuant to the applicable Lease or Leases and the Administrative Agent
receives all documents and opinions in connection therewith that it may
reasonably request, including, without limitation, an opinion from counsel of
the Borrower to the extent that the Borrower as lessor and the Administrative
Agent as the assignee under the Lease are entitled to the benefits of Section
1110 of the Bankruptcy Code with respect to such property. To the extent that
Insurance Proceeds or Condemnation Proceeds received upon the occurrence of an
Event of Loss with respect to an Aircraft or Spare Engine are not reinvested in
accordance with the preceding sentence, then the Borrower shall prepay, without
premium or penalty (other than pursuant to subsection 2.6D), those Loans
relating to the Aircraft or Spare Engine Pool in respect of which such
Insurance Proceeds or Condemnation Proceeds were received based on the
outstanding principal amount of each Loan as compared to the total outstanding
principal amount of all Loans relating to such Aircraft or Spare Engine Pool.
Any amount of the Proceeds remaining (a) after prepayment of the Loans
described in the immediately preceding sentence and/or (b) after being
reinvested in the manner described in the second preceding sentence, shall be
applied ratably to the prepayment of Loans relating to all of the remaining
Aircraft and Spare Engine Pools based on the outstanding principal amount of
each such Loan as compared to the total outstanding principal amount of all
Loans relating to all of the remaining Aircraft and Spare Engine Pools. Any
such mandatory prepayments shall be applied as specified in subsection
2.4C(iii). Until such time as such Proceeds are reinvested in replacement
aircraft or spare engines or applied to repay Loans, such proceeds shall be
held by the Administrative Agent in a cash collateral account with the
Administrative Agent as security for the Obligations pursuant to a cash
collateral agreement in form and substance satisfactory to the Administrative
Agent and providing that such proceeds may be invested in Cash or

                                      -30-

<PAGE>

Cash Equivalents at the direction of the Borrower with any earnings thereon
being for the account of the Borrower.

         (d)      Prepayments under Leases. On any date on which the Borrower
receives any prepayments of rent or other amounts pursuant to the terms of any
Lease, the Borrower shall prepay, without premium or penalty (other than
pursuant to subsection 2.6), the outstanding principal amount of Loans relating
to the Aircraft or Spare Engine Pool that is the subject of the Lease pursuant
to which such prepayments were made and, to the extent that such payments are
in excess of the principal amount of Loans relating to such Aircraft or Spare
Engine Pool, such excess proceeds shall be applied to make an additional
prepayment of Loans relating to all of the remaining Aircraft and Spare Engine
Pools based on the outstanding principal amount of each such Loan as compared
to the total outstanding principal amount of all Loans relating to all of the
remaining Aircraft and Spare Engine Pools.

       (iii)      Application of Prepayments.

         (a)      Application of Voluntary Prepayments by Type of Loans and
Order of Maturity. Any voluntary prepayments pursuant to subsection 2.4C(i)
shall be applied ratably among the Loans relating to all of the Aircraft and
both Spare Engine Pools based on the outstanding principal amount of each such
Loan as compared to the total outstanding principal amount of all Loans. All
voluntary prepayments of the Loans pursuant to subsection 2.4C(i) shall be
applied pro rata to all scheduled amortization payments.

         (b)      Application of Mandatory Prepayments of Loans. Any mandatory
prepayments of the Loans pursuant to subsection 2.4C(ii) shall be applied
ratably among the Loans relating to all of the Aircraft and both Spare Engine
Pools based on the outstanding principal amount of each such Loan as compared
to the total outstanding principal amount of all Loans; provided, that in the
event of a prepayment pursuant to subsection 2.4C(ii)(a) such prepayment shall
be applied first to the Loans relating to such Aircraft or Spare Engine Pool
that were the subject of the Asset Sale on a pro rata basis based on the
outstanding principal amount of each Loan as compared to the total outstanding
principal amount of all Loans relating to such Aircraft or Spare Engine Pool
and second, ratably among the Loans relating to all other Aircraft and Spare
Engine Pools on a pro rata basis based on the outstanding principal amount of
the Loan being prepaid as compared to the total outstanding principal amount of
all Loans relating to all other Aircraft and Spare Engine Pools. Any mandatory
prepayments of the Loans pursuant to subsection 2.4C(ii)(b) or (c) shall be
applied to the Loans relating to the particular Aircraft or Spare Engine Pool,
retained by the Borrower and/or applied ratably among the Loans relating to all
other Aircraft and Spare Engine Pools in accordance with such sections. All
mandatory prepayments of the Loans pursuant to subsection 2.4C(ii) shall be
applied to scheduled amortization payments in inverse order of maturity.

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

       (iii)      Apportionment of Payments. Aggregate principal and interest
payments in respect of Tranche A Loans shall be apportioned among all
outstanding Tranche A Loans to which such payments relate, in each case
proportionately to each Tranche A Lender's respective Tranche A Pro Rate Share.
Aggregate principal and interest payments in respect of Tranche B Loans shall
be apportioned among all outstanding Tranche B Loans to which such payments
relate, in each case proportionately to each Tranche B Lender's respective
Tranche B Pro Rata Share. The Administrative Agent shall promptly distribute to
each Lender, at its address set forth below its name on the signature page
hereof or at such other address as such Lender may request, its Tranche A Pro
Rata Share of all such payments received by the Administrative Agent in respect
of Tranche A Loans, and its Tranche B Pro Rate Share of all such payments
received by the Administrative Agent in respect of Tranche B Loans.

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

         (v)      Notation of Payment. Each Lender agrees that before disposing
of any Note held by it, or any part thereof (other than by granting
participations therein), that Lender will make a notation thereon of all Loans
evidenced by that Note and all principal payments previously made thereon and
of the date to which interest thereon has been paid; provided, that the failure
to make (or any error in the making of) a notation of any Loan made under

                                      -32-

<PAGE>

such Note shall not limit or otherwise affect the obligations of the Borrower
hereunder or under such Note with respect to any Loan or any payments of
principal or interest on such Note.

2.5  USE OF PROCEEDS.

         A.       APPLICATION OF PROCEEDS. The proceeds of the Loans shall be
applied solely (I)(x) to consummate the Refinancing and (y) to pay fees and
expenses related to the Refinancing and the other transactions contemplated
hereby, (II) (x) to finance the Transfers and (y) to pay fees and expenses
related to the Transfers and the other transactions contemplated hereby, (III)
to pay fees and expenses related to the Atlas Contribution and the other
transactions contemplated hereby and (IV) to the extent that there are proceeds
remaining after application pursuant to preceding clauses (I), (II) and (III),
for general corporate purposes, including the payment of dividends to Atlas
permitted hereunder.

         B.       MARGIN REGULATIONS. No portion of the proceeds of any
borrowing under this Agreement shall be used by the Borrower in any manner that
might cause the borrowing or the application of such proceeds to violate
Regulation U, Regulation T or Regulation X of the Board of Governors of the
Federal Reserve System, or any other regulation of such Board, or to violate
the Exchange Act, in each case as in effect on the date or dates of such
borrowing and such use of proceeds.

2.6  SPECIAL PROVISIONS GOVERNING LOANS.

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

         A.       DETERMINATION OF APPLICABLE INTEREST RATE. As soon as
practicable after 10:00 A.M. (New York time) on each Interest Rate
Determination Date, the Administrative Agent shall determine (which
determination shall, absent manifest error, be final, conclusive and binding
upon all parties) the interest rate that shall apply to the Loans for which an
interest rate is then being determined for the applicable Interest Period and
shall promptly give notice thereof (in writing or by telephone confirmed in
writing) to the Borrower and to each Lender.

         B.       INABILITY TO DETERMINE APPLICABLE INTEREST RATE. In the event
that the Administrative Agent shall have determined (which determination shall
be final and conclusive and binding upon all parties hereto), on any Interest
Rate Determination Date with respect to any Loans, that, by reason of
circumstances affecting the interbank Eurodollar market, adequate and fair
means do not exist for ascertaining the interest rate applicable to such Loans
on the basis provided for in the definition of Adjusted Eurodollar Rate, the
Administrative Agent shall on such date give notice (by telefacsimile or by
telephone confirmed in writing) to the Borrower and to each Lender of such
determination, whereupon (i) no Loans may be incurred until such time as the
Administrative Agent notifies the Borrower and the

                                      -33-

<PAGE>

Lenders that the circumstances giving rise to such notice no longer exist, or
until the Borrower, the Administrative Agent and the Lenders agree upon a
Substitute Basis in accordance with Section 2.6G and (ii) the rate of interest
applicable to any Affected Loans then outstanding shall be determined in
accordance with Section 2.6G.

         C.       ILLEGALITY OR IMPRACTICABILITY OF LOANS. In the event that on
any date any Lender shall have determined (which determination shall be final
and conclusive and binding upon all parties hereto but shall be made only after
consultation with the Borrower and the Administrative Agent) that the making,
maintaining or continuation of its Loans (i) has become unlawful as a result of
compliance by such Lender in good faith with any law, treaty, governmental
rule, regulation, guideline or order (or would conflict with any such treaty,
governmental rule, regulation, guideline or order not having the force of law
even though the failure to comply therewith would not be unlawful) or (ii) has
become impracticable, or would cause such Lender material hardship, as a result
of contingencies occurring after the date of this Agreement that materially and
adversely affect the interbank Eurodollar market or the position of such Lender
in that market, then, and in any such event, such Lender shall be an "AFFECTED
LENDER" and it shall on that day give notice (by telefacsimile or by telephone
confirmed in writing) to the Borrower and the Administrative Agent of such
determination (which notice the Administrative Agent shall promptly transmit to
each other Lender). Thereafter, (a) the obligation of the Affected Lender to
make Loans shall be suspended until such notice shall be withdrawn by the
Affected Lender, (b) the Affected Lender's obligation to maintain its
outstanding Loans (the "AFFECTED LOANS") shall be suspended until such notice
shall be withdrawn by the Affected Lender, and (c) the parties shall follow the
procedures set forth in Section 2.6G with respect to the Affected Loans so long
as, if following such procedures, the maintaining of such Loans is lawful.
Notwithstanding the foregoing, to the extent that a determination by an
Affected Lender as described above relates to a borrowing then being requested
by the Borrower subject to the provisions of subsection 2.6D, the Borrower
shall have the option, subject to the provisions of subsection 2.6D, to rescind
such borrowing as to all Lenders by giving notice (by telefacsimile or by
telephone confirmed in writing) to the Administrative Agent of such rescission
on the date on which the Affected Lender gives notice of its determination as
described above (which notice of rescission the Administrative Agent shall
promptly transmit to each other Lender). Except as provided in the immediately
preceding sentence, nothing in this subsection 2.6C shall affect the obligation
of any Lender other than an Affected Lender to make or maintain Loans in
accordance with the terms of this Agreement.

         D.       COMPENSATION FOR BREAKAGE OR NON-COMMENCEMENT OF INTEREST
PERIODS. The Borrower shall compensate each Lender, upon written request by
such Lender (which request shall set forth the basis for requesting such
amounts), for all reasonable losses, expenses and liabilities (including,
without limitation, any interest paid by such Lender to lenders of funds
borrowed by it to make or carry its Loans and any loss, expense or liability
sustained by such Lender in connection with the liquidation or reemployment of
such funds)

                                      -34-

<PAGE>

that such Lender may sustain: (i) if for any reason (other than a default by
such Lender) a borrowing of any Loan does not occur on a date specified
therefor in a Notice of Borrowing or a telephonic request for borrowing, (ii)
if any prepayment or other principal payment occurs on a date prior to the last
day of an Interest Period applicable to such Loan, (iii) if any prepayment of
any of its Loans is not made on any date specified in a notice of prepayment
given by the Borrower, or (iv) as a consequence of any other default by the
Borrower in the repayment of its Loans when required by the terms of this
Agreement.

         E.       BOOKING OF LOANS. Any Lender may make, carry or transfer
Loans at, to, or for the account of any of its branch offices or the office of
an Affiliate of that Lender.

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

         G.       SUBSTITUTE BASIS. During the 30 days following the date of
any notice given to the Borrower pursuant to subsections 2.6B and 2.6C, the
Administrative Agent, the Lenders and the Borrower shall negotiate in good
faith in order to arrive at a mutually acceptable alternative basis for
determining the interest rate from time to time applicable to the affected
Loans (the "SUBSTITUTE BASIS"). If, within the 30 days following the date of
any such notice to the Borrower, the Administrative Agent, the Lenders and the
Borrower shall agree upon a Substitute Basis, such Substitute Basis shall be
retroactive to and effective from the first day of the then current Interest
Period until and including the last day of such Interest Period. If, after 30
days from the date of such notice, the Lenders and the Borrower shall have
failed to agree upon a Substitute Basis, then each Lender shall certify in
writing to the Borrower through the Administrative Agent (such certification to
be conclusive and binding on all of the parties hereto absent manifest error)
the interest rate at which such Lender is prepared to make or maintain its
affected Loan for such Interest Period, it being understood that such Lender's
interest rate shall be at a rate per annum equal to the sum of the Applicable
Margin plus, a rate which adequately and fairly reflects the cost to such
Lender of obtaining the funds necessary to maintain its affected Loan for such
Interest Period, such interest rate to be retroactive to and effective from the
first day of such Interest Period. If no Substitute Basis is established, upon
receipt of notice of the interest rates at which the Lenders are prepared to
make or maintain their respective affected Loans, the Borrower shall have the
right, exercisable upon ten Business Days' prior notice to any Lender through
the Administrative Agent,

                                      -35-

<PAGE>


(A) to continue to borrow Loans at the interest rates so advised by the
respective Lenders (as such rates may be modified, from time to time, at the
outset of each subsequent Interest Period) or (B) to prepay in full the
Affected Loans of any Lender, together with accrued interest thereon at the
interest rate certified in writing by such Lender as provided above, whereupon
such Affected Loans shall become due and payable on the date specified by the
Borrower in such notice. In determining the actual interest rate per annum to
be charged on any Loan, the Substitute Basis or the interest rate advised by
the respective Lenders to apply to a Loan in accordance with the provisions of
this subsection 2.6G shall be increased to the rate per annum obtained by
dividing the Substitute Basis or such advised interest rate by a percentage
equal to 100% minus the then stated maximum rate of all required reserve
requirements under applicable law (including any marginal, emergency,
supplemental, special or other reserves) and applicable on the date of
determination of such interest rate to any member bank of the Federal Reserve
System in respect of "Eurocurrency liabilities" as defined in Regulation D of
the Board of Governors of the Federal Reserve System, as in effect from time to
time (or any successor category of liabilities under Regulation D).

2.7  INCREASED COSTS, TAXES; CAPITAL ADEQUACY.

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

         (i)      subjects such Lender (or its applicable lending office) to
any additional Tax (other than any change in the rate of Tax on the overall net
income of such Lender) with respect to this Agreement or any of its obligations
hereunder or any payments to such Lender (or its applicable lending office) of
principal, interest, fees or any other amount payable hereunder;

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

                                      -36-

<PAGE>

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

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

         B.       WITHHOLDING OF TAXES.

         (i)      Payments to Be Free and Clear. All sums payable by the
Borrower under this Agreement and the other Loan Documents shall be paid free
and clear of and (except to the extent required by law) without any deduction
or withholding on account of any Tax (excluding, except as provided in
subsection 27B(ii)(e), any Tax on the overall net income of any Lender)
imposed, levied, collected, withheld or assessed by any jurisdiction or by any
political subdivision or taxing authority thereof or therein with respect to
such payments.

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

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

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

         (c)      the sum payable by the Borrower in respect of which the
relevant deduction, withholding or payment is required shall be increased to
the extent necessary to ensure that, after the making of that deduction,
withholding or payment, the Administrative

                                      -37-

<PAGE>

Agent or such Lender, as the case may be, receives on the due date a net sum
equal to what it would have received had no such deduction, withholding or
payment been required or made;

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

         (e)      if any amounts are payable in respect of Taxes pursuant to
subsection 2.7B(ii)(c), the Borrower agrees to reimburse each Lender, upon the
written request of such Lender, for taxes imposed on or measured by the overall
net income of such Lender and for any withholding of taxes as such Lender shall
determine are payable by, or withheld from, such Lender, in respect of such
amounts so paid to or on behalf of such Lender pursuant to subsection
2.7B(ii)(c), and in respect of any amounts paid to or on behalf of such Lender
pursuant to this subsection 2.7B(ii)(e).

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

         (a)      Each Lender that is organized under the laws of any
jurisdiction other than the United States or any state or other political
subdivision thereof (for purposes of this subsection 2.7B(iii), a "NON-U.S.
LENDER") shall deliver to the Administrative Agent for transmission to the
Borrower, on or prior to the Effective Date (in the case of each Lender listed
on the signature pages hereof) or on the date of the Assignment Agreement
pursuant to which it becomes a Lender (in the case of each other Lender that
was not a Lender hereunder immediately prior to such assignment or transfer),
and at such other times as may be necessary in the determination of the
Borrower or the Administrative Agent (each in the reasonable exercise of its
discretion), (1) two original copies of Internal Revenue Service Form W-8ECI or
Form W-8BEN (with respect to a complete exemption under an income tax treaty)
(or any successor forms), properly completed and duly executed by such Lender,
certifying to such Lender's entitlement to a complete exemption from United
States withholding tax with respect to any payments to such Lender under any of
the Loan Documents or (2) if such Lender is not a "bank" or other Person
described in Section 881(c)(3) of the Internal Revenue Code and cannot deliver
either Internal Revenue Service Form W-8ECI or Form W-8BEN (with respect to a
complete exemption under an income tax treaty) pursuant to clause (1) above, a
Certificate re Non-Bank Status together with two original copies of Internal
Revenue Service Form W-8BEN (with respect to the portfolio interest exemption)
(or any successor form), properly completed and duly executed by such Lender,
certifying to such Lender's entitlement to a complete exemption from United
States withholding tax with respect to any payments to such Lender of interest
payable under any of the Loan Documents.

         (b)      Each Lender required to deliver any forms, certificates or
other evidence with respect to United States federal income tax withholding
matters pursuant to sub-

                                      -38-

<PAGE>


section 2.7B(iii)(a) hereby agrees, from time to time after the initial
delivery by such Lender of such forms, certificates or other evidence, whenever
a lapse in time or change in circumstances renders such forms, certificates or
other evidence obsolete or inaccurate in any material respect, such Lender
shall (1) deliver to the Administrative Agent for transmission to the Borrower
two new original copies of Internal Revenue Service Form W-8ECI or Form W-8BEN
(with respect to the benefits of any income tax treaty), or a Certificate re
Non-Bank Status and two original copies of Internal Revenue Service Form W-8BEN
(with respect to the portfolio interest exemption), as the case may be,
properly completed and duly executed by such Lender, together with any other
certificate or statement of exemption required in order to confirm or establish
the entitlement of such Lender to a continued exemption from or reduction in
United States withholding tax with respect to payments to such Lender under the
Loan Documents or (2) immediately notify the Administrative Agent and the
Borrower of its inability to deliver any such forms, certificates or other
evidence, in which case such Lender shall not be required to deliver any such
forms, certificates or other evidence pursuant to this subsection 2.7B(iii)(b).

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

        (iv)      If the Borrower pays any additional amount under this
subsection 2.7B to a Lender and such Lender determines in its sole discretion
that it has actually received or realized in connection therewith any refund or
any reduction of, or credit against, its Tax liabilities in or with respect to
the taxable year in which the additional amount is paid, such Lender shall pay
to the Borrower an amount that such Lender shall, in its sole discretion,
determine is equal to the net benefit, after tax, that was obtained by the
Lender in such year as a consequence of such refund, reduction or credit;
provided, however, that (i) any Lender may determine, in its sole discretion
consistent with the policies of such Lender, whether to seek a Tax Benefit;
(ii) any Taxes that are imposed on a Lender as a result of a disallowance or
reduction (including through the expiration of any tax credit carryover or
carryback of such Lender that otherwise would not have expired) of any Tax
Benefit with respect to which such Lender has made a payment to the Borrower
pursuant to this Section 2.7B(iv) shall be treated as a Tax for which the
Borrower is obligated to indemnify such Lender pursuant to this Sec-

                                      -39-

<PAGE>

tion 2.7B(iv) without any exclusions or defenses; and (iii) nothing in this
Section 2.7B(iv) shall require the Lender to disclose any confidential
information to the Borrower (including , without limitation, its tax returns).

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

         D.       SUBSTITUTE LENDERS. In the event that the Borrower is
required under the provisions of subsection 2.6C or this subsection 2.7 to make
payments in a material amount to any Lender or in the event that any Lender
fails to lend to the Borrower in accordance with this Agreement, the Borrower
may, so long as, no Event of Default or Potential Event of Default shall have
occurred and be continuing, elect to terminate such Lender as a party to this
Agreement, so long as, concurrently with such termination, (i) the Borrower
pays to that Lender all principal, interest and fees and other amounts
(including, without limitation, amounts, if any, owed under subsection 2.6C or
this subsection 2.7) owed to such Lender through such date of termination, (ii)
another financial institution satisfactory to the Borrower and the
Administrative Agent (or if the Administrative Agent is also the Lender to be
terminated, the successor Administrative Agent) agrees, as of such date, to
become a Lender for all purposes under this Agreement (whether by assignment or
amendment) and to assume all obligations of the Lender to be terminated as of
such date, and (iii) all documents and supporting materials necessary, in the
judgment of the Administrative Agent (or if the Administrative Agent is also
the Lender to be terminated, the successor Administrative Agent) to evidence

                                      -40-

<PAGE>

the substitution of such Lender have been received and approved by the
Administrative Agent as of such date.

2.8  OBLIGATION OF LENDERS TO MITIGATE.

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

                                   SECTION 3.

                              CONDITIONS TO LOANS

3.1  CONDITIONS TO LOANS.

         The obligations of the Lenders to make the Loans on the Initial
Borrowing Date are subject to prior or concurrent satisfaction of the following
conditions:

         A.   BORROWER AND ATLAS DOCUMENTS. On or before the Initial Borrowing
Date, the Borrower shall deliver or cause to be delivered to the Lenders (or to
the Administrative Agent for the Lenders with sufficient originally executed
copies, where appropriate, for each Lender and its counsel) the following,
each, unless otherwise noted, dated the Effective Date:

                                      -41-

<PAGE>

         (i)      certified copies of the certificate or articles of
incorporation of the Borrower and Atlas, together with a good standing
certificate from the Secretary of State of the State of Delaware and each other

Contingent Obligation, contingent liability or liability for taxes, long-term

or obligations with respect to Atlas and its Subsidiaries or to the Borrower of
any nature whatsoever (whether absolute, accrued, contingent or otherwise and
whether or not due) that, either individually or in aggregate, could reasonably
be expected to be material to Atlas and its Subsidiaries taken as a whole but
excluding the Borrower, or to the Borrower on a stand-alone basis. As of the
Effective Date, neither Atlas nor the Borrower knows of any basis for the
assertion against it or, in the case of Atlas, against it or its Subsidiaries,
of any liability or obligation of any nature whatsoever that is not fully
disclosed in the financial statements delivered pursuant to Section 4.3A that,
either individually or in the aggregate, could reasonably be expected to be
material to Atlas and its Subsidiaries taken as a whole but excluding the
Borrower, or to the Borrower on a stand-alone basis.

4.4  NO MATERIAL ADVERSE CHANGE; NO RESTRICTED JUNIOR PAYMENTS.

         (i)               Since December 31, 1999, no event or change has
occurred that has caused or evidences, either in any case or in the aggregate,
a Material Adverse Effect.

        (ii)      Since December 31, 1999, the Borrower has not directly or
indirectly declared, ordered, paid or made, or set apart any sum or property
for, any Restricted Junior Payment or agreed to do so, except as permitted by
subsection 6.5.

4.5  TITLE TO PROPERTIES, LIENS.

horsepower or the equivalent of such horsepower. Each Aircraft is registered
with the FAA in the name of the Borrower and Atlas has authority to operate
such Aircraft.

4.6  LITIGATION, ADVERSE FACTS.

         There are no actions, suits, proceedings, arbitrations or governmental
investigations (whether or not purportedly on behalf of the Borrower) at law or
in equity or in admiralty or before or by any federal, state, municipal or
other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, pending or, to the knowledge of the
Borrower, threatened against or affecting the Borrower or any property of the
Borrower or with respect to the Transaction that could reasonably be expected
to result in a Material Adverse Effect. The Borrower is not (i) in violation of
any applicable laws that, individually or in the aggregate, could reasonably be
expected to result in a Material Adverse Effect or (ii) subject to or in
default with respect to any final judgments, writs, injunctions, decrees, rules
or regulations of any court or any federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,

all taxes, assessments, fees and other governmental charges upon the Borrower
and upon its respective properties, assets, income, businesses and franchises
that are due and payable have been paid when due and payable. The Borrower does
not know of any proposed tax assessment against it that is not being actively
contested by it in good faith and by appropriate proceedings; provided, that
such reserves or other appropriate provisions, if any, for liabilities for
taxes as shall be required in conformity with GAAP shall have been made or
provided for in the financial statements of the Borrower. There are no
agreements with respect to taxes or waiver extending any statute of limitations
relating to the payment or correction of taxes between the Borrower and any tax
agency or authority.

         The Borrower is not in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in any
of its Contractual Obligations, and no condition exists that, with the giving
of notice or the lapse of time or both, would constitute such a default, except
where the consequences, direct or indirect, of such default or defaults, if
any, would not have a Material Adverse Effect.

reasonable exercise of diligence, be known) to the Borrower (other than matters
of a general economic nature) that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect and that have not
been disclosed herein or in such other documents, certificates and statements
furnished to the Lenders for use in connection with the transactions
contemplated hereby.

(provided, that the Borrower may, if it so chooses, be present at or
participate in any such discussion), all upon reasonable notice and at such
reasonable times during normal business hours and as often as may be reasonably
requested, provided, so long as no Event of Default has occurred and is
continuing, that such inspection is not disruptive to the Borrower's business,
as reasonably determined by the Borrower. Without in any way limiting the
foregoing, the Borrower will, upon the request of the Administrative Agent or
Requisite Lenders, participate in a meeting of the Administrative Agent and
Lenders once during each Fiscal Year to be held at the Borrower's corporate

Administrative Agent.

5.6  COMPLIANCE WITH LAWS, ETC.

expected to cause a Material Adverse Effect. The Borrower shall not conduct,

to have a Material Adverse Effect.

connection with Environmental Claims against the Borrower or with any Hazardous

Release of any Hazardous Materials on, under or about any facility in order to
comply with all applicable Environmental Laws and Governmental Authorizations.
In the event that the Borrower undertakes any remedial action with respect to
any Hazardous Materials on, under or about any such facility, the Borrower will
conduct and complete such remedial action in compliance with all applicable
Environmental Laws, and in accordance with the policies, orders and directives
of all federal, state and local governmental authorities except when, and only
to the extent that, the Borrower's liability for such presence, storage, use,
disposal, transportation or Release of any such Hazardous Materials is being
contested in good faith by the Borrower. Notwithstanding anything to the
contrary contained in the Transaction Documents, the Borrower or Lessee may
engage in the transportation of Hazardous Materials in the ordinary course of
business so long as such is conducted in compliance with all applicable
Environmental Laws and all other applicable laws, policies, orders, regulations

fully the purposes of the Loan Documents and to provide for payment of the
Obligations in accordance with the terms of this Agreement, the Notes and the
other Loan Documents.

5.13 CORPORATE SEPARATENESS.

         The Borrower will take all such action as is necessary to keep its
operations separate and apart from those of Atlas or any of its Affiliates,
including, without limitation, ensuring that all customary corporate
formalities, including the maintenance of separate corporate records and
documents and holding regular meetings, are followed. Any financial statements
distributed to any creditors of the Borrower shall clearly establish the
corporate separateness of the Borrower from Atlas and each of Atlas's other
Subsidiaries. The Borrower shall not take any action or conduct its affairs in
a manner that is likely to result in the corporate existence of the Borrower on
the one hand and of Atlas or any Subsidiary of Atlas on the other hand being
disregarded, or in the assets and liabilities of Atlas or any Subsidiary of
Atlas being substantively consolidated with those of the Borrower in a
bankruptcy, reorganization or other insolvency proceeding. The Borrower shall
have at all times at least one Independent Director who shall be satisfactory
to the Administrative Agent. The Borrower shall maintain its principal
executive office separate from Atlas or any of its Affiliates, which may be
subleased from Atlas on an arm's-length basis or maintained as provided in the
Service Agreement.

         The Borrower shall pay out of its own funds fees for its directors and
salaries of its officers and employees, and shall promptly reimburse any
Affiliate for any services provided to the Borrower by such Affiliate;
provided, however, that Atlas may advance funds on behalf of the Borrower to
pay for the expenses of its organization and funding. All such advances shall
be duly and properly recorded and promptly repaid as intercompany advances. The
Borrower shall not commingle any of its funds or other assets with the funds or
assets of any other entity or person. The Borrower will maintain separate bank
accounts in its own name.

         The assets of the Borrower shall be separately identified and
segregated. All of the Borrower's assets shall at all times be held by or on
behalf of the Borrower, and, if held on behalf of the Borrower by another
entity, shall at all times be kept identifiable (in accordance with customary
usages) as assets owned by the Borrower. In no event shall any of the
Borrower's assets be held by Atlas or by any other Affiliate. The Borrower
shall pay from its assets all obligations and indebtedness of any kind incurred
by the Borrower, and shall not pay from its assets any obligations or
indebtedness of any other entity or person. The liabilities of the Borrower
will be separately managed from those of any Affiliate, and all liabilities,
including all administrative expenses, shall be paid from its own separate
assets; provided, however, that the Borrower will be included, to the extent
permitted by law, in the affiliated group of corporations of which Atlas is the
"common parent" for federal income tax returns filed for such affiliated group
by Atlas.

respect of goods or accounts receivable) of the Borrower, whether now owned or
hereafter acquired, or any income or profits therefrom, or file or permit the
filing of, or permit to remain in effect, any financing statement or other
similar notice of any Lien with respect to any such property, asset, income or
profits under the Uniform Commercial Code of any state or under any similar
recording or notice statute, except for Permitted Encumbrances.

                  B.   NO NEGATIVE PLEDGES. The Borrower shall not enter into
any agreement prohibiting the creation or assumption of any Lien upon any of its
properties or assets, whether now owned or hereafter acquired.

provided, that the Borrower may make payments pursuant to the Service Agreement
in an aggregate annual amount not to exceed $200,000 per annum; and provided
further, that, so long as no Event of Default or Potential Event of Default has
occurred and is continuing, or would result therefrom, within five Business Days
of any payment made under any of the Leases by Atlas to the Borrower, to the
extent that such payment is in excess of amounts owing to the Lenders under the
Loan Documents, the Borrower may distribute such excess amounts to Atlas as a
dividend, to the extent that the Borrower, after giving effect to such dividend,
has no other liabilities and maintains a reserve of Cash or Cash Equivalents
adequate to fund all expenses of the Borrower (exclusive of payments under the
Loan Documents) to be incurred during the next four quarters following such
dividend.

                  The Borrower for any reason ceases to be a United States
Citizen;

THEN (I) (i) upon the occurrence of any Event of Default described in
subsection 7.6 or 7.7, each of (a) the unpaid principal amount of and accrued
interest on the Loans and (b) all other Obligations shall automatically become
immediately due and payable, without presentment, demand, protest or other

terminate and (ii) upon the occurrence and during the continuation of any other
Event of Default, the Administrative Agent shall, upon the written request or
with the written consent of Requisite Lenders, by written notice to the

interest and all payments on account of principal which shall have become due
otherwise than as a result of such acceleration (with interest on principal and,
to the extent permitted by law, on overdue interest, at the rates specified in
this Agreement) and all Events of Default and Potential Events of Default (other
than non-payment of the principal of and accrued interest on the Loans, in each
case that is due and payable solely by virtue of acceleration) shall be remedied
or waived pursuant to subsection 9.6, then Requisite Lenders, by written notice
to the Borrower, may at their option rescind and annul such acceleration and its
consequences, but such action shall not affect any


                                      -66-
<PAGE>



subsequent Event of Default or Potential Event of Default or impair any right
consequent thereon. The provisions of this paragraph are intended merely to bind
the Lenders to a decision that may be made at the election of Requisite Lenders
and are not intended to benefit the Borrower and do not grant to the Borrower
the right to require the Lenders to rescind or annul any acceleration hereunder,
even if the conditions set forth herein are met.

                                   SECTION 8.

                            THE ADMINISTRATIVE AGENT

8.1      APPOINTMENT.


                  Each Lender hereby appoints Bankers Trust Company as
Administrative Agent hereunder and under the other Loan Documents, and each
Lender hereby authorizes the Administrative Agent to act as its agent in
accordance with the terms of this Agreement and the other Loan Documents. The
Administrative Agent agrees to act upon the express conditions contained in this
Agreement and the other Loan Documents, as applicable. The provisions of this
Section 8 are solely for the benefit of the Administrative Agent and the
Lenders, and the Borrower shall have no rights as a third-party beneficiary of
any of the provisions thereof. In performing its functions and duties under this
Agreement, the Administrative Agent shall act solely as an agent of the Lenders
and does not assume and shall not be deemed to have assumed any obligation
towards or relationship of agency or trust with or for the Borrower.

8.2      POWERS AND DUTIES; GENERAL IMMUNITY.

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

                  B.   NO RESPONSIBILITY FOR CERTAIN MATTERS. The Administrative
Agent shall not be responsible to any Lender for the execution, effectiveness,
genuineness, validity,


                                      -67-
<PAGE>



enforceability, collectibility or sufficiency of this Agreement or any other
Loan Document or for any representations, warranties, recitals or statements
made herein or therein or made in any written or oral statements or in any
financial or other statements, instruments, reports or certificates or any other
documents furnished or made by the Administrative Agent to any Lender or by or
on behalf of the Borrower to the Administrative Agent or any Lender in
connection with the Loan Documents and the transactions contemplated thereby or
for the financial condition or business affairs of the Borrower or any other
Person liable for the payment of any Obligations, nor shall the Administrative
Agent be required to ascertain or inquire as to the performance or observance of
any of the terms, conditions, provisions, covenants or agreements contained in
any of the Loan Documents or as to the use of the proceeds of the Loans or as to
the existence or possible existence of any Event of Default or Potential Event
of Default. Anything contained in this Agreement to the contrary
notwithstanding, the Administrative Agent shall not have any liability arising
from confirmations of the amount of outstanding Loans or the component amounts
thereof.

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

                  D.   ADMINISTRATIVE AGENT ENTITLED TO ACT AS LENDER. The
agency hereby created shall in no way impair or affect any of the rights and
powers of, or impose any duties or obligations upon, the Administrative Agent in
its individual capacity as a Lender hereunder. With respect to its
participations in the Loans, the Administrative Agent shall have the same rights
and powers hereunder as any other Lender and may exercise the same as though it
were not performing the duties and functions delegated to it hereunder, and the
term "Lender"


                                      -68-
<PAGE>


or "Lenders" or any similar term shall, unless the context clearly otherwise
indicates, include the Administrative Agent in its individual capacity. The
Administrative Agent and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of banking, trust, financial advisory or other
business with the Borrower or any of its Affiliates 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 Lenders.

8.3      REPRESENTATIONS AND WARRANTIES; NO RESPONSIBILITY FOR APPRAISAL OF
         CREDITWORTHINESS.

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

8.4      RIGHT TO INDEMNITY.

                  Each Lender, in proportion to its Pro Rata Share, severally
agrees to indemnify the Administrative Agent (and its affiliates and partners),
to the extent that the Administrative Agent shall not have been reimbursed by
the Borrower, for and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including,
without limitation, counsel fees and disbursements) or disbursements of any kind
or nature whatsoever which may be imposed on, incurred by or asserted against
the Administrative Agent in exercising its powers, rights and remedies or
performing its duties hereunder or under the other Loan Documents or otherwise
in its capacity as Administrative Agent, in any way relating to or arising out
of this Agreement or the other Loan Documents; provided, that no Lender shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such Administrative Agent's gross negligence or willful misconduct.

8.5      COLLATERAL DOCUMENTS.

                  Without limiting the generality of subsection 8.1, each Lender
hereby further authorizes the Administrative Agent to enter into the Collateral
Documents as secured party on behalf of and for the benefit of such Lender and
agrees to be bound by the terms of each of


                                      -69-
<PAGE>


the Collateral Documents; provided, that, except as otherwise provided below,
the Administrative Agent shall not enter into or consent to any amendment,
modification, termination or waiver of any provision contained in any Collateral
Document without prior written consent of Requisite Lenders. Anything contained
in any of the Loan Documents to the contrary notwithstanding, each Lender agrees
that no Lender shall have any right individually to realize upon any of the
collateral under any Collateral Document, it being understood and agreed that
all powers, rights and remedies under the Collateral Documents may be exercised
solely by the Administrative Agent for the benefit of the Lenders in accordance
with the terms thereof. Each Lender hereby authorizes the Administrative Agent
(i) to release or subordinate Collateral as permitted or required under this
Agreement or the Collateral Documents, and agrees that a certificate executed by
the Administrative Agent evidencing such release of Collateral shall be
conclusive evidence of such release as to any third party and (ii) to enter into
any amendments of the Collateral Documents to cure any ambiguity, defect or
inconsistency or to amend provisions relating to ministerial or administrative
matters that do not materially adversely affect the rights of the Lenders
thereunder.

8.6      SUCCESSOR ADMINISTRATIVE AGENT.

                  The Administrative Agent may resign at any time by giving 30
days' prior written notice thereof to the Lenders and the Borrower. Upon any
such notice of resignation, Requisite Lenders shall have the right, upon
consultation with the Borrower, to appoint a successor Administrative Agent.
Upon the acceptance of any appointment hereunder by a successor Administrative
Agent, that successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent and the retiring or removed Administrative Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring Administrative Agent's resignation hereunder as Administrative Agent,
the provisions of this Section 8 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement.

                                   SECTION 9.

                                  MISCELLANEOUS

9.1      ASSIGNMENTS AND PARTICIPATIONS IN LOANS.

                  A.   GENERAL. Each Lender shall have the right at any time (i)
to sell, assign or transfer to any Eligible Assignee, or (ii) to sell
participations to any Person in, all or any part of its Commitment or any Loan
or Loans made by it or any other interest herein or in any other Obligations
owed to it, so long as no such sale, assignment, transfer or participation
shall, without the consent of the Borrower, require the Borrower to file a
registration state-


                                      -70-
<PAGE>


ment with the Securities and Exchange Commission or apply to qualify such sale,
assignment, transfer or participation under the securities laws of any state;
provided, that no such sale, assignment or transfer described in clause (i)
above shall be effective unless and until an Assignment Agreement effecting such
sale, assignment or transfer shall have been accepted by the Administrative
Agent and recorded in the Register as provided in subsection 9.1B(ii). Except as
otherwise provided in this subsection 9.1, no Lender shall, as between the
Borrower and such Lender, be relieved of any of its obligations hereunder as a
result of any sale, assignment or transfer of, or any granting of participations
in, all or any part of its Commitment or the Loans, or the other Obligations
owed to such Lender.

                  B.   ASSIGNMENTS.

                   (i)   Amounts and Terms of Assignments. Each Commitment, Loan
or other Obligation may (a) be assigned in any amount to another Lender, or to
an Affiliate or Related Fund of the assigning Lender or another Lender, with the
giving of notice to the Borrower and the Administrative Agent or (b) be assigned
in an aggregate amount of not less than $5,000,000 (or such lesser amount as
shall constitute the aggregate amount of the Commitments, Loans, and other
Obligations of the assigning Lender) to any other Eligible Assignee with the
giving of notice to the Borrower and with the consent of the Administrative
Agent and the Borrower (which consent shall not be unreasonably withheld or
delayed) unless (I) an Event of Default shall have occurred and be occurring or
(II) such assignment is consented to by the Administrative Agent within 15 days
after the Initial Borrowing Date, in each of which cases the consent of the
Borrower to such assignment shall not be required. Any assignment of Loans
hereunder shall effect a pro rata assignment of the Notes with respect to each
Aircraft or Spare Engine Pool. To the extent of any such assignment in
accordance with either clause (a) or (b) above, the assigning Lender shall be
relieved of its obligations with respect to its Commitment, Loans, or other
Obligations or the portion thereof so assigned. The parties to each such
assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment Agreement, together with
a processing and recordation fee of $3,000 and such forms, certificates or other
evidence, if any, with respect to United States federal income tax withholding
matters as the assignee under such Assignment Agreement may be required to
deliver to the Administrative Agent pursuant to subsection 2.7B(iii)(a);
provided, however, that such processing fee shall not be required where the
assignee is an existing Lender. Upon such execution, delivery, acceptance and
recording from and after the effective date specified in such Assignment
Agreement, (y) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment Agreement, shall have the rights and obligations of a Lender
hereunder and (z) the assigning Lender thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment Agreement, relinquish its rights and be released from its obligations
under this Agreement (and, in the case of an Assignment Agreement covering all
or the remaining portion of an assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto);


                                      -71-
<PAGE>




provided further, however, that the assigning Lender shall retain any right to
payment accrued under subsections 2.6C, 2.6D, 2.7, 9.2 or 9.3 unless such rights
are explicitly assigned to the assignee in the Assignment Agreement. The
Commitments hereunder shall be modified to reflect the Commitment of such
assignee and any remaining Commitment of such assigning Lender and, if any such
assignment occurs after the issuance of the Notes hereunder, the assigning
Lender shall, upon the effectiveness of such assignment or as promptly
thereafter as practicable, surrender its applicable Notes to the Administrative
Agent for cancellation, and thereupon new Notes shall be issued to the assignee
substantially in the form of Exhibit IIA annexed hereto or Exhibit IIB annexed
hereto, as appropriate, with appropriate insertions, to reflect the new
Commitment or outstanding Loans, as the case may be, of the assignee and/or the
assigning Lender.

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

                  C.   PARTICIPATIONS. The holder of any participation, other
than an Affiliate of the Lender granting such participation, shall not be
entitled to require such Lender to take or omit to take any action hereunder
except action directly affecting (i) the extension of the Final Maturity Date
of any Loan allocated to such participation, (ii) a reduction of the principal
amount of or the rate of interest payable on any Loan allocated to such
participation or (iii) a release of Collateral, and all amounts payable by the
Borrower hereunder (including, without limitation, amounts payable to such
Lender pursuant to subsections 2.6D and 2.7) shall be determined as if such
Lender had not sold such participation. The Borrower and each Lender hereby
acknowledge and agree that, solely for purposes of subsection 9.5, (a) any
participation will give rise to a direct obligation of the Borrower to the
participant and (b) the participant shall be considered to be a "Lender."

                  D.   ASSIGNMENTS TO FEDERAL RESERVE BANKS AND OTHERS.  In
addition to the assignments and participations permitted under the foregoing
provisions of this subsection


                                      -72-
<PAGE>



9.1, any Lender may assign and pledge all or any portion of its Loans, the
other Obligations owed to such Lender, and its Notes to (i) any Federal Reserve
Bank as collateral security pursuant to Regulation A of the Board of Governors
of the Federal Reserve System and any operating circular issued by such Federal
Reserve Bank or (ii) if such Lender is a "fund", to any holders of obligations
owed or securities issued by such fund as security for such obligations or
securities, or to any trustee for, or any representative of, such holders;
provided, that (i) no Lender shall, as between the Borrower and such Lender, be
relieved of any of its obligations hereunder as a result of any such assignment
and pledge and (ii) in no event shall such Federal Reserve Bank or lender be
considered to be a "Lender" or be entitled to require the assigning Lender to
take or omit to take any action hereunder.

                  E.   INFORMATION. Each Lender may furnish any information
concerning the Borrower in the possession of that Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject to subsection 9.19.

9.2      EXPENSES.

                  Whether or not the transactions contemplated hereby shall be
consummated, the Borrower agrees to pay promptly (i) all the actual and
reasonable costs and expenses of preparation of the Loan Documents; (ii) all the
costs of furnishing all opinions by counsel for the Borrower (including, without
limitation, any opinions requested by the Lenders as to any legal matters
arising hereunder) and of the Borrower's performance of and compliance with all
agreements and conditions on its part to be performed or complied with under
this Agreement and the other Loan Documents, including, without limitation, with
respect to confirming compliance with environmental and insurance requirements;
(iii) the reasonable fees, expenses and disbursements of counsel to the
Administrative Agent in connection with the negotiation, preparation, execution
and administration of the Loan Documents and the Loans and any consents,
amendments, waivers or other modifications hereto or thereto and any other

of creating and perfecting the Liens in favor of the Administrative Agent for
the benefit of the Lenders pursuant to the Loan Documents, including filing and

expenses of legal counsel to the Administrative Agent (including local
counsel); (v) all other actual and reasonable costs and expenses incurred by the
Administrative Agent in connection with the syndication of the Commitments and
the Loans and the negotiation, preparation and execution of the Loan Documents
and the transactions contemplated hereby and thereby, provided that such costs
and expenses of syndication shall not exceed $25,000; and (vi) after the
occurrence of an Event of Default, all costs and expenses, including reasonable
attorneys' fees (including allocated costs of internal counsel) and costs of
settlement, incurred by the Administrative Agent and the Lenders in enforcing
any Obligations of or in collecting any payments due from the Borrower hereunder
or under the other Loan Documents by reason of such Event of Default or in
connection with any refinancing or re-


                                      -73-

structuring of the credit arrangements provided under this Agreement in the
nature of a "work-out" or pursuant to any insolvency or bankruptcy proceedings.

9.3      INDEMNITY.

                  In addition to the payment of expenses pursuant to subsection
9.2, whether or not the transactions contemplated hereby shall be consummated,
the Borrower agrees to defend, indemnify, pay and hold harmless the
Administrative Agent and the Lenders, and the officers, directors, partners,
employees, agents and affiliates of the Administrative Agent and the Lenders
(collectively called the "INDEMNITEES") from and against any and all other
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, expenses and disbursements of any kind or nature whatsoever
(including, without limitation, the reasonable fees and disbursements of counsel
for such Indemnitees in connection with any investigative, administrative or
judicial proceeding, commenced or threatened by any Person, whether or not any
such Indemnitee shall be designated as a party or a potential party thereto),
whether direct, indirect or consequential and whether based on any federal,
state or foreign laws, statutes, rules or regulations (including, without
limitation, securities and commercial laws, statutes, rules or regulations and
Environmental Laws), on common law or equitable cause or on contract or
otherwise, that may be imposed on, incurred by, or asserted against any such
Indemnitee, in any manner relating to or arising out of this Agreement or the
other Loan Documents or the transactions contemplated hereby or thereby
(including, without limitation, the Lenders' agreement to make the Loans
hereunder, or the use or intended use of the proceeds of any of the Loans) or
the statements contained in the commitment letter delivered by any Lender to the
Borrower with respect thereto (collectively called the "INDEMNIFIED
LIABILITIES"); provided, that the Borrower shall not have any obligation to any
Indemnitee hereunder with respect to any Indemnified Liabilities to the extent
such Indemnified Liabilities arise solely from the gross negligence or willful
misconduct of that Indemnitee as determined by a final judgment of a court of
competent jurisdiction. To the extent that the undertaking to defend, indemnify,
pay and hold harmless set forth in the preceding sentence may be unenforceable
because it is violative of any law or public policy, the Borrower shall
contribute the maximum portion that it is permitted to pay and satisfy under
applicable law to the payment and satisfaction of all Indemnified Liabilities
incurred by the Indemnitees or any of them.

9.4      SET-OFF.

                  In addition to any rights now or hereafter granted under
applicable law and not by way of limitation of any such rights, upon the
occurrence of any Event of Default each Lender is hereby authorized by the
Borrower at any time or from time to time, without notice to the Borrower or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and to apply any and all deposits (general or special, including,
but not limited to, Indebtedness evidenced by certificates of deposit, whether
matured or unmatured, but not including trust accounts) and any other
Indebtedness at any time held or owing by that


                                      -74-
<PAGE>



Lender to or for the credit or the account of the Borrower against and on
account of the obligations and liabilities of the Borrower to that Lender under
this Agreement, its Notes, and the other Loan Documents, including, but not
limited to, all claims of any nature or description arising out of or connected
with this Agreement, the Notes, or any other Loan Document, irrespective of
whether or not (i) that Lender shall have made any demand hereunder or (ii) the
principal of or the interest on the Loans or any other amounts due hereunder
shall have become due and payable pursuant to Section 7 and although said
obligations and liabilities, or any of them, may be contingent or unmatured.

9.5      RATABLE SHARING.

                  The Lenders hereby agree among themselves that if any of them
shall, whether by voluntary payment, by realization upon security, through the
exercise of any right of set-off or banker's lien, by counterclaim or cross
action or by the enforcement of any right under the Loan Documents or otherwise,
or as adequate protection of a deposit treated as cash collateral under the
Bankruptcy Code, receive payment or reduction of a proportion of the aggregate
amount of principal, interest, fees and other amounts then due and owing to that
Lender hereunder or under the other Loan Documents (collectively, the "AGGREGATE
AMOUNTS DUE" to such Lender) that is greater than the proportion received by any
other Lender in respect of the Aggregate Amounts Due to such other Lender, then
the Lender receiving such proportionately greater payment shall (i) notify the
Administrative Agent and each other Lender of the receipt of such payment and
(ii) apply a portion of such payment to purchase participations (which it shall
be deemed to have purchased from each seller of a participation simultaneously
upon the receipt by such seller of its portion of such payment) in the Aggregate
Amounts Due to the other Lenders so that all such recoveries of Aggregate
Amounts Due shall be shared by all Lenders in proportion to the Aggregate
Amounts Due to them; provided, that if all or part of such proportionately
greater payment received by such purchasing Lender is thereafter recovered from
such Lender upon the bankruptcy or reorganization of the Borrower or otherwise,
those purchases shall be rescinded and the purchase prices paid for such
participations shall be returned to such purchasing Lender ratably to the extent
of such recovery, but without interest. The Borrower expressly consents to the
foregoing arrangement and agrees that any holder of a participation so purchased
may exercise any and all rights of banker's lien, set-off or counterclaim with
respect to any and all monies owing by the Borrower to that holder with respect
thereto as fully as if that holder were owed the amount of the participation
held by that holder.

9.6      AMENDMENTS AND WAIVERS.

                  A.   No amendment, modification, termination or waiver of any
provision of this Agreement or any of the other Loan Documents (other than any
amendment, modification, termination or waiver which may be required to effect
the replacement of any Engine or any Airframe in accordance with Section 9.21 of
this Agreement or the sale of a single Aircraft in accordance with Section
6.6(ii) of this Agreement), or consent to and departure by the


                                      -75-
<PAGE>



Borrower therefrom, shall in any event be effective without the written
concurrence of Requisite Lenders; provided, that any such amendment,
modification, termination, waiver or consent that: increases the amount of any
of the Commitments or reduces the principal amount of any of the Loans; changes
any Lender's Tranche A Pro Rata Share or Tranche B Pro Rata Share; changes in
any manner the definition of "Requisite Lenders;" changes in any manner any
provision of this Agreement that, by its terms, expressly requires the approval
or concurrence of all Lenders; postpones the Final Maturity Date (but not the
date of any scheduled installment of principal) of any of the Loans; postpones
the date on which any interest or any fees are payable; decreases the interest
rate borne by any of the Loans (other than any waiver of any increase in the
interest rate applicable to any of the Loans pursuant to subsection 2.2D) or the
amount of any fees payable hereunder; releases all or substantially all of the
Collateral; or changes in any manner the provisions contained in this subsection
9.6 shall be effective only if evidenced by a writing signed by or on behalf of
all Lenders to whom are owed Obligations being directly affected by such
amendment, modification, termination, waiver or consent. In addition, (i) no
amendment, modification, termination or waiver of any provision of any Note
shall be effective without the written concurrence of the Lender that is the
holder of that Note, (ii) no increase in the Commitment of any Lender over the
amount thereof then in effect shall be effective without the written concurrence
of that Lender, it being understood and agreed that in no event shall waivers or
modifications of conditions precedent, covenants, Events of Default, Potential
Events of Default or of a mandatory prepayment or a reduction of any or all of
the Commitments be deemed to constitute an increase of the Commitment of any
Lender, and that an increase in the available portion of any Commitment of any
Lender shall not be deemed to constitute an increase in the Commitment of such
Lender and (iii) no amendment, modification, termination or waiver of any
provision of Section 8 or of any other provision of this Agreement that, by its
terms, expressly requires the approval or concurrence of the Administrative
Agent shall be effective without the written concurrence of such Administrative
Agent. No change shall be made (x) to Section 2.4B(a) or (b) without the consent
of the holders of a majority of principal of the Tranche A Loans or Tranche B
Loans, respectively, and (y) to Section 2.4C(iii) without the consent of the
holders of a majority of principal of each of the Tranche A Loans and Tranche B
Loans. The Administrative Agent may, but shall have no obligation to, with the
concurrence of any Lender, execute amendments, modifications, waivers or
consents on behalf of that Lender. Any waiver or consent shall be effective only
in the specific instance and for the specific purpose for which it was given. No
notice to or demand on the Borrower in any case shall entitle the Borrower to
any other or further notice or demand in similar or other circumstances. Any
amendment, modification, termination, waiver or consent effected in accordance
with this subsection 9.6 shall be binding upon each Person who was a Lender at
the time of such amendment, modification, termination, waiver or consent, upon
each Person who subsequently becomes a Lender and, if signed by the Borrower,
upon the Borrower.

                  B.   If, in connection with any proposed change, waiver,
discharge or termination to any of the provisions of this Agreement as
contemplated by the proviso in the first


                                      -76-
<PAGE>


sentence of this subsection 9.6, the consent of Requisite Lenders is obtained
but consent of one or more of such other Lenders whose consent is required is
not obtained, then the Borrower may, so long as all non-consenting Lenders are
so treated, elect to terminate such Lender as a party to this Agreement, so long
as, concurrently with such termination, (i) the Borrower pays to that Lender all
principal, interest and fees and other amounts owed to such Lender through such
date of termination, (ii) another financial institution satisfactory to the
Borrower and the Administrative Agent (or if the Administrative Agent is also
the Lender to be terminated, the successor Administrative Agent) agrees, as of
such date, to become a Lender for all purposes under this Agreement (whether by
assignment or amendment) and to assume all obligations of the Lender to be
terminated as of such date, and (iii) all documents and supporting materials
necessary, in the judgment of the Administrative Agent (or if the Administrative
Agent is also the Lender to be terminated, the successor Administrative Agent)
to evidence the substitution of such Lender have been received and approved by
the Administrative Agent as of such date.

9.7      INDEPENDENCE OF COVENANTS.

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

9.8      NOTICES.

                  Unless otherwise specifically provided herein, any notice or
other communication herein required or permitted to be given shall be in writing
and may be personally served, telexed or sent by telefacsimile or United States
mail or courier service and shall be deemed to have been given when delivered in
person or by courier service, upon receipt of telefacsimile or telex, or three
Business Days after depositing it in the United States mail with postage prepaid
and properly addressed; provided, that notices to the Administrative Agent shall
not be effective until received. For the purposes hereof, the address of each
party hereto shall be as set forth under such party's name on the signature
pages hereof or (i) as to the Borrower and the Administrative Agent, such other
address as shall be designated by such Person in a written notice delivered to
the other parties hereto and (ii) as to each other party, such other address as
shall be designated by such party in a written notice delivered to the
Administrative Agent.

9.9      SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

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


                                      -77-
<PAGE>



                  B.   Notwithstanding anything in this Agreement or implied by
law to the contrary, the agreements of the Borrower set forth in subsections
2.6D, 2.7, 9.2, 9.3 and 9.4 and the agreements of the Lenders set forth in
subsections 8.2C, 8.4 and 9.5 shall survive the payment of the Loans, and the
termination of this Agreement.

9.10     FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.

                  No failure or delay on the part of the Administrative Agent or
any Lender in the exercise of any power, right or privilege hereunder or under
any other Loan Document shall impair such power, right or privilege or be
construed to be a waiver of any default or acquiescence therein, nor shall any
single or partial exercise of any such power, right or privilege preclude other
or further exercise thereof or of any other power, right or privilege. All
rights and remedies existing under this Agreement and the other Loan Documents
are cumulative to, and not exclusive of, any rights or remedies otherwise
available.

9.11     MARSHALLING; PAYMENTS SET ASIDE.

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

9.12     SEVERABILITY.

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

9.13     OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS' RIGHTS.

                  The obligations of the Lenders hereunder are several and no
Lender shall be responsible for the obligations or Commitments of any other
Lender hereunder. Nothing contained herein or in any other Loan Document, and no
action taken by any Lenders pursuant


                                      -78-
<PAGE>



hereto or thereto, shall be deemed to constitute the Lenders as a partnership,
an association, a joint venture or any other kind of entity. The amounts payable
at any time hereunder to each Lender shall be a separate and independent debt,
and each Lender shall be entitled to protect and enforce its rights arising out
of this Agreement, and it shall not be necessary for any other Lender to be
joined as an additional party in any proceeding for such purpose.

9.14     HEADINGS.

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

9.15     APPLICABLE LAW.

                  THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED

9.16     SUCCESSORS AND ASSIGNS.

                  This Agreement shall be binding upon the parties hereto and
their respective successors and assigns and shall inure to the benefit of the
parties hereto and the successors and assigns of the Lenders (it being
understood that the Lenders' rights of assignment are subject to subsection
9.1). Neither the Borrower's rights or obligations hereunder nor any interest
therein may be assigned or delegated by the Borrower without the prior written
consent of all Lenders.

9.17     CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

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

AGREEMENT, THE BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS
PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE
AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS AND IRREVOCABLY
AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS
AGREEMENT, SUCH OTHER LOAN DOCUMENT OR SUCH OBLIGATION (SUBJECT TO ANY RIGHT TO
APPEAL TO A COURT IN THE STATE OF NEW YORK). The Borrower hereby agrees that
service of all process in any such proceeding in any such court may be made by
registered or certified



                                      -79-

subsection 9.8, such service being hereby acknowledged by the Borrower to be
sufficient for personal jurisdiction in any action against the Borrower in any
such court and to be otherwise effective and binding service in every respect.
Nothing herein shall affect the right to serve process in any other manner
permitted by law or shall limit the right of any Lender to bring proceedings
against the Borrower in the courts of any other jurisdiction.

9.18     WAIVER OF JURY TRIAL.

                  EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE
ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON
OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR ANY
DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION OR
THE LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED. The scope of this
waiver is intended to be all-encompassing of any and all disputes that may be
filed in any court and that relate to the subject matter of this transaction,
including, without limitation, contract claims, tort claims, breach of duty
claims and all other common law and statutory claims. Each party hereto
acknowledges that this waiver is a material inducement to enter into a business
relationship, that each has already relied on this waiver in entering into this
Agreement, and that each will continue to rely on this waiver in their related
future dealings. Each party hereto further warrants and represents that it has
reviewed this waiver with its legal counsel and that it knowingly and
voluntarily waives its jury trial rights following consultation with legal
counsel. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER

LOAN DOCUMENTS OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THE LOANS
MADE HEREUNDER. In the event of litigation, this Agreement may be filed as a
written consent to a trial by the court.

9.19     CONFIDENTIALITY.

                  Each Lender shall hold all non-public information obtained
pursuant to the requirements of the Transaction Documents that has been
identified as confidential by the Borrower in accordance with such Lender's
customary procedures for handling confidential information of this nature, it
being understood and agreed by the Borrower that in any event a Lender may make
disclosures to any Person who evaluates, approves, structures or administers the
Loans on behalf of a Lender and who is subject to this confidentiality
provision, or, subject to this Section 9.19, reasonably required by any bona
fide assignee, transferee or participant in connection with the contemplated
assignment or transfer by such Lender of any Loans or any participation therein
(at which time, any such assignee, transferee or participant shall be bound by
this Section 9.19) or as required or requested by any governmental or regu-


                                      -80-
<PAGE>

latory agency (including, without limitation, the National Association of
Insurance Commissions) or representative thereof or pursuant to legal process or
in accordance with any applicable law or regulation; provided, that, unless
specifically prohibited by applicable law or court order, each Lender shall
notify the Borrower of any request by any governmental or regulatory agency or
representative thereof (other than any such request in connection with any
examination of the financial condition of such Lender by such governmental or
regulatory agency) for disclosure of any such non-public information prior to
disclosure of such information; and provided further, that in no event shall any
Lender be obligated or required to return any materials furnished by the
Borrower.

9.20     COUNTERPARTS; EFFECTIVENESS.

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

                  B.   This Agreement shall become effective upon the execution
of a counterpart hereof by each of the parties hereto and receipt by the
Borrower and the Administrative Agent of written or telephonic notification of
such execution and authorization of delivery thereof (the "EFFECTIVE DATE").

9.21     REPLACEMENT ENGINES AND AIRFRAMES.

                  A.   ENGINES. So long as no Event of Default or Potential
Event of Default has occurred and is continuing, the Borrower may, upon not less
than 5 Business Days' prior written notice to the Administrative Agent, replace
any Engine that is the subject of an Aircraft Chattel Mortgage with another
engine (the "Replacement Engine") meeting the requirements of the applicable
Aircraft Chattel Mortgage and the requirements of an Acceptable Alternate
Engine. In addition to the requirements of the preceding sentence, any
Replacement Engine shall be an engine that is the same or improved make and
model as the Engine to be replaced, and that is suitable for installation and
use on any Airframe (or any Boeing 747-400 aircraft operated by Atlas) and that
has a value, utility and remaining useful life (including with respect to hours
and cycles remaining until overhaul) at least equal to the Engine to be replaced
thereby.

                  The Lenders agree to release the Lien created by the
applicable Aircraft Chattel Mortgage for any Engine to be replaced by a
Replacement Engine promptly upon (i) presentation by the Borrower of
documentation necessary to create a legal, valid and enforceable first priority
security interest in and to the Replacement Engine, (ii) delivery to the
Adminis-


                                      -81-
<PAGE>

trative Agent of an opinion of Cahill Gordon & Reindel, or such other counsel as
may be acceptable to the Administrative Agent, confirming that the Borrower (and
the Administrative Agent upon succeeding to the Borrower's interest in the
applicable Lease) will continue to be entitled to the benefits of Section 1110
of the Bankruptcy Code with respect to such Replacement Engine free of all Liens
(other than Permitted Encumbrances and the applicable Lease) and (iii) receipt
of all other deliveries required by Section 4(f)(ii) of the applicable Aircraft
Chattel Mortgage.

                  B.   AIRFRAMES. So long as no Event of Default or Potential
Event of Default has occurred and is continuing, the Borrower may, upon not less
than 5 Business Days' prior notice to the Administrative Agent, replace any
Airframe that is the subject of an Aircraft Chattel Mortgage with another
airframe (the "Replacement Airframe") meeting the requirements of the applicable
Aircraft Chattel Mortgage and the requirements of an Acceptable Alternate
Airframe; provided that, no more than two Airframes may be replaced by the
Borrower pursuant to this subsection 9.21B. In addition to the requirements of
the preceding sentence, any Replacement Airframe shall be an airframe that is
the same or improved make and model as the Airframe to be replaced and that has
a value, utility and remaining useful life (including with respect to hours and
cycles remaining until overhaul) at least equal to the Airframe to be replaced
thereby.

                  The Lenders agree to release the Lien created by the
applicable Aircraft Chattel Mortgage for any Airframe to be replaced by a
Replacement Airframe promptly upon (i) presentation by the Borrower of
documentation necessary to create a legal, valid and enforceable first priority
security interest in and to the Replacement Airframe, (ii) delivery to the
Administrative Agent of an opinion of Cahill Gordon & Reindel, or such other
counsel as may be acceptable to the Administrative Agent, confirming that the
Borrower (and the Administrative Agent upon succeeding to the Borrower's
interest in the applicable Lease) will continue to be entitled to the benefits
of Section 1110 of the Bankruptcy Code with respect to such Replacement Airframe
free of all Liens (other than Permitted Encumbrances and the applicable Lease)
and (iii) receipt of all other deliveries required by Section 4(f)(ii) of the
applicable Aircraft Chattel Mortgage.

                  C.   FURTHER ASSURANCES. The Borrower shall, in addition to
the actions required by the preceding subsections 9.21A and 9.21B, take all
necessary actions to provide that the Borrower (and the Administrative Agent
upon succeeding to the Borrower's interest in the applicable Lease) will
continue to be entitled to the benefits of Section 1110 of the Bankruptcy Code
with respect to each Replacement Engine and each Replacement Airframe, in each
case free of all Liens (other than Permitted Encumbrances and the applicable
Lease).

                             W I T N E S S E T H :

         WHEREAS, the Lessee desires to lease from the Lessor and the Lessor is
willing to lease to the Lessee the Aircraft upon the terms and subject to the
conditions of this Lease;

         WHEREAS, the Lessor and the Lessee desire that this be a net lease;

         WHEREAS, the Lessor has incurred certain Loans under the Credit
Agreement in connection with the Aircraft to be leased pursuant to the terms of
this Lease and other similar aircraft and spare engines to be leased pursuant to
the other Leases:

         WHEREAS, the Lessor and the Lessee desire that this Lease be, and be
treated as, a Lease for federal income tax purposes.

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained and other good and valuable consideration, the Lessor and the Lessee
hereby agree as follows:

         SECTION 1. All capitalized terms used herein shall have the respective
meanings set forth in this section.

         "ACCEPTABLE ALTERNATE AIRFRAME" means a Boeing 747-200 that is in a
cargo configuration capable of immediate operation in the business of the Lessee
and has a maximum gross takeoff weight of at least 800,000 pounds and is of the
equivalent or greater residual value, condition, utility, airworthiness, and
remaining useful life and that shall have been maintained, serviced, repaired
and overhauled in substantially the same manner as required under this Lease
without in any way discriminating against such airframe.

         "ACCEPTABLE ALTERNATE ENGINE" means a General Electric CF6-50E2 engine
or an engine of the same or another manufacturer of equivalent or greater
residual value, condition, utility, airworthiness, and remaining useful life and
suitable for installation and use on the Airframe; provided, that such engine
shall be of the same make, model and manufacturer as the other engines installed
on the Airframe, shall be an engine of a type then being utilized by Lessee on
other Boeing 747-200 aircraft operated by Lessee, and shall have been
maintained, serviced, repaired and overhauled in substantially the same manner

<PAGE>


         "ACMI CONTRACT" means (i) any contract entered into by the Lessee
pursuant to which the Lessee furnishes the aircraft, crew, maintenance and
insurance and customers bear all other operating expenses and (ii) any similar
contract in which the customer provides the flight crew, all substantially in
accordance with the Lessee's historical practices.

         "ACMI CONTRACTED AIRCRAFT" means an aircraft acquired by the Lessee or
its Subsidiaries and intended to be used in connection with an ACMI Contract
entered into at the time of the acquisition of such aircraft (which ACMI
Contract shall not represent a renewal or replacement of a prior ACMI Contract
unless the aircraft used pursuant to such prior ACMI Contract was operated under
an operating lease and returned to the lessor) which is in effect on the date of
calculation and has a remaining term of one year or more on the date such
aircraft was intended to be used in connection with such ACMI Contract (subject
to cancellation terms, which may include the right to cancel on six months
notice). When making any calculation on a Pro Forma Basis, effect shall be given
to the acquisition of an ACMI Contracted Aircraft by adding to the appropriate
components of Consolidated Adjusted EBITDA (i) the net projected annualized
revenues from the operation of the ACMI Contracted Aircraft under such ACMI
Contract for that portion of the period for which Consolidated Adjusted EBITDA
is being calculated prior to the acquisition of such aircraft, assuming
operation for the minimum guaranteed number of block hours (less any block hours
subject to cancellation) at the minimum guaranteed rate under such ACMI Contract
less (ii) the projected annualized cash operating expenses from such operation
for the same period for which the related projected revenues are determined in
clause (i) above; provided, that such projected cash operating expenses shall
not be less on a per block hour basis than the average historical per block hour
operating expenses of the Lessee for the four full fiscal quarters immediately
preceding the date of calculation; and provided further, that if such aircraft
is of a model other than a Boeing 747 freighter, such projected cash operating
expenses shall include maintenance costs which shall not be less than the
average for such aircraft type disclosed on the most recently available DOT
Forms 41 with respect to such aircraft type or any summary of such data as
reported in a nationally recognized industry publication. For purposes of this
definition, "ACMI CONTRACT" shall include contracts pursuant to which the Lessee
does not pay any crew costs, in which event pro forma effect shall be given as
described above but excluding from the projected annualized cash operating
expenses all crew costs. Cash operating expenses means for purposes of this
definition consolidated operating expenses, less consolidated depreciation and
amortization and Consolidated Rental Payments, to the extent included in
computing consolidated operating expenses.

         "AFFILIATE" means, as applied to any Person, any other Person directly

control with"), as applied to any Person, means the possession, directly or
indirectly, of the power to direct or cause the direction of the management

installed in or attached thereto or that have been removed therefrom, but where
title to which remains vested in the Lessor in accordance with this Lease.

         "AMENDED AIRCRAFT CREDIT FACILITY" means the Fourth Amended and
Restated Credit Agreement dated as of April 25, 2000, among the Lessee, as
borrower, the lenders listed therein, and Bankers Trust Company, as
administrative agent, without giving effect to any amendments, modifications,
supplements or waivers thereof.

and 9.3 of the Credit Agreement; provided, however, that, to the extent that any
Supplemental Rent required to be paid pursuant to clause (iii) of this
subsection 2(c) has been paid by the Lessee pursuant to the terms of another
Lease, then the Lessee's obligations hereunder shall be deemed to be satisfied
by the payments made pursuant to such other Lease.

         (d) Payments in General. All payments of Rent shall be made directly by
the Lessee prior to 12:00 p.m. (New York time), to the Lessor at its office at
538 Commons Drive, Golden, CO 80401, Attention: Richard H. Shuyler (or such
other office of the Lessor in the continental United States or such other
account as the Lessor shall direct in a notice to the Lessee at least 10
Business Days prior to the date when such payment of Rent is due); provided,
that, so long as any Obligations remain outstanding, all Rent shall be paid
directly to the Agent at the Funding and Payment Office; and provided further,
that to the extent the amount of Rent paid directly to the Agent is in excess of
the amount of principal and interest on the Loans relating to the Aircraft and
other unpaid Obligations (other than principal and interest on other Loans
relating to other aircraft or spare engines leased pursuant to the other Leases
and after taking into account all other payments of rent pursuant to the other
Leases on such date), then such excess amounts shall be paid by the Agent to the
Lessor at its above-referenced office.

         Notwithstanding anything to the contrary contained herein, if any date
on which a payment of Rent becomes due and payable is not a Business Day, then
such payment shall be made on the next succeeding Business Day; provided,
however, that if any date on which a payment of Rent becomes due is not a
Business Day and is a day of the month after which no further Business Day
occurs in such month, then the payment of Rent shall be made on the next
preceding Business Day. No interest shall accrue on the amount of any payment
made on the Business Day next succeeding the regularly scheduled Basic Rent
Payment Date, if such payment is made on such next succeeding Business Day
because the original date of


                                      -23-
<PAGE>



         payment was not a Business Day (it being understood that the amount of
Basic Rent includes Rent for such day).

         (e) Minimum Rent. Anything herein to the contrary notwithstanding,

         (i) each installment of Basic Rent, whether or not such installment has
     been adjusted pursuant to Section 3(b), together with all prior Basic Rent
     due and payable on such date and all accrued interest thereon shall be,
     under all circumstances and in any event, in an amount at least sufficient
     for the Lessor to pay in full principal and interest on the Loans relating
     to the Aircraft required to be paid by the Lessor on or within five
     Business Days of the due date of such installment of Basic Rent; and

         (ii) payments of Stipulated Loss Value shall be, under any
     circumstances and in any event, in an amount that (when taken together with
     any other Basic Rent due and payable in connection therewith) is at least
     equal to, as of the date of payment, the sum of the aggregate unpaid
     principal of and accrued interest on the Loans relating to the Aircraft and
     all other unpaid Obligations of the Lessor (other than principal and
     interest on Loans relating to other aircraft or spare engines and after
     taking into account all other payments of Stipulated Loss Value pursuant to
     the other Leases on such date).

         (f) Prepayment of Rent Payments:

         (i) In the event that the Lessor is at any time required to repay Loans
     relating to the Aircraft pursuant to Section 2.4C(ii) of the Credit
     Agreement, the Lessor shall notify the Lessee of such required prepayment
     and the Lessee shall immediately prepay an amount of Basic Rent equal to
     the amount of such required prepayment less any required payments of the
     Loans relating to the Aircraft actually made by the Lessor from Insurance
     Proceeds or Condemnation Proceeds (as each such term is defined in the
     Credit Agreement) received directly by the Lessor.

         (ii) The Lessee shall also be permitted to prepay Basic Rent
     voluntarily at any time and from time to time, without premium or penalty,
     upon not less than three Business Days' prior written or telephonic notice
     to the Lessor and the Agent.

         (iii) In the event of any prepayment pursuant to this Section 3(f), the
     schedules of Basic Rent and Stipulated Loss Value shall be adjusted so as
     to preserve the after tax yield and after tax cash flows of the Lessor and,
     to the extent consistent therewith, to minimize the net present value of
     Basic Rent payments. All such computations shall be made on the basis of
     the same assumptions and the method of computations employed in the
     original calculations of Basic Rent and Stipulated Loss Values (except to
     the extent that such assumptions have been changed as a result of such
     prepayment or any prior such adjustment). At the Lessee's written request,
     independ-


                                      -24-
<PAGE>


     ent public accountants mutually selected by the Lessor and the
     Lessee shall confirm the required adjustments. The final determination of
     any adjustment hereunder shall be set forth in amendments to this Lease,
     executed and delivered by the Lessor, the Lessee and consented to by the
     Agent. The reasonable fees, costs and expenses of the verifying accounting
     firm shall be paid by the Lessee.

         Anything contained in the foregoing to the contrary notwithstanding,
after giving effect to the foregoing adjustments, the revised Basic Rent and
Stipulated Loss Values shall permit the Lessee to comply with Section 3(e)
hereof.

         SECTION 4. Certain Representations and Warranties.  THE LESSEE
ACKNOWLEDGES AND AGREES THAT, AS BETWEEN THE LESSOR AND THE LESSEE (A) THE
AIRFRAME AND EACH ENGINE ARE OF A SIZE, DESIGN, CAPACITY AND MANUFACTURE
SELECTED BY AND ACCEPTABLE TO THE LESSEE AND THE LESSEE TAKES THE SAME "AS IS,"
(B) THE LESSEE IS SATISFIED THAT THE AIRFRAME AND EACH ENGINE ARE SUITABLE FOR
ITS PURPOSES, (C) THE LESSOR IS NOT A MANUFACTURER OR A DEALER IN PROPERTY OF
SUCH KIND, AND (D) NEITHER THE LESSOR NOR THE AGENT NOR ANY LENDER MAKES, HAS
MADE OR SHALL BE DEEMED TO HAVE MADE, AND EACH WILL BE DEEMED TO HAVE EXPRESSLY
DISCLAIMED, ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE TITLE,
AIRWORTHINESS, VALUE, CONDITION, DESIGN, OPERATION, MERCHANTABILITY OR FITNESS
FOR USE FOR A PARTICULAR PURPOSE OF THE AIRCRAFT OR ANY PART THEREOF, AS TO THE
ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE
ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK, COPYRIGHT OR OTHER
PROPRIETARY RIGHT, AS TO THE ABSENCE OF OBLIGATIONS BASED ON STRICT LIABILITY IN
TORT, OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED,
WITH RESPECT TO THE AIRCRAFT OR ANY PART THEREOF, except that the Lessor
covenants that it will not, through its own actions or inactions, in such
capacity, interfere in the Lessee's quiet enjoyment of the Aircraft unless this
Lease shall have been declared or deemed to have been declared in default
pursuant to Section 17 hereof. None of the provisions of this Section 4 or any
other provision of this Lease shall be deemed to amend, modify or otherwise
affect the representations, warranties or other obligations (express or implied)
of any manufacturer, any affiliate thereof, any subcontractor or supplier of any
manufacturer or any affiliate thereof, with respect to the Airframe, Engines or
any Parts, or to release the manufacturer, any affiliate thereof, or any such
subcontractor or supplier from any such representation, warranty or obligation.
Unless a Default or Lease Event of Default shall have occurred and be
continuing, the Lessor agrees to make available to the Lessee such rights as the
Lessor may have under any warranty with respect to the Aircraft made by the
manufacturer or any affiliate thereof or any of its subcontractors or suppliers
and any other claims against the manufacturer or any affiliate thereof, or


                                      -25-
<PAGE>


any such subcontractor or supplier with respect to the Aircraft, all pursuant to
and in accordance with the terms of any applicable purchase agreements or
warranty agreements.

         SECTION 5. Lessee's Representations and Warranties. In order to induce
the Lessor to enter into this Lease and the Agent and the Lenders to make the
Loans under the Credit Agreement, the Lessee represents and warrants to the
Lessor, the Agent and each Lender on the date of this Lease that the following
statements are true, correct and complete:

         (a) Organization, Powers, Qualification, Good Standing, Business and
Subsidiaries.

         (i) Organization and Powers. The Lessee is a corporation duly
     organized, validly existing and in good standing under the laws of the
     State of Delaware. The Lessee has all requisite corporate power and
     authority to own and operate its properties, to carry on its business as
     now conducted and as proposed to be conducted, to enter into this Lease and
     the other Transaction Documents and to carry out the transactions
     contemplated hereby and thereby.

         (ii) Qualification and Good Standing. The Lessee is qualified to do
     business and in good standing in every jurisdiction where its assets are
     located and wherever necessary to carry out its business and operations,
     except in jurisdictions where the failure to be so qualified or in good
     standing has not had and will not have a Material Adverse Effect.

         (iii) Subsidiaries. All of the Subsidiaries of the Lessee as of the
     Initial Borrowing Date are identified on Schedule 5(a)(iii) annexed hereto.
     The capital stock of each of the Subsidiaries of the Lessee identified in
     Schedule 5(a)(iii) annexed hereto (as so supplemented) is duly authorized,
     validly issued, fully paid and nonassessable and none of such capital stock
     constitutes Margin Stock. Each of the Subsidiaries of the Lessee identified
     in Schedule 5(a)(iii) annexed hereto is a corporation duly organized,
     validly existing and in good standing under the laws of its respective
     jurisdiction of incorporation set forth therein, has all requisite
     corporate power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted, and
     is qualified to do business and in good standing in every jurisdiction
     where its assets are located and wherever necessary to carry out its
     business and operations, in each case except where failure to be so
     qualified or in good standing or a lack of such corporate power and
     authority has not had and will not have a Material Adverse Effect. Schedule
     5(a)(iii) annexed hereto correctly sets forth the ownership interest of the
     Lessee and each of its Subsidiaries in each of the Subsidiaries of the
     Lessee identified therein.

         (b) Authorization of Transaction Documents, etc.

         (i) Authorization of Transaction Documents. The execution, delivery and
     performance of this Lease and the other Transaction Documents have been
     duly authorized by all necessary corporate action on the part of the Lessee
     or its Subsidiaries, as the case may be.

         (ii) No Conflict. The execution, delivery and performance by the Lessee
     or its Subsidiaries, as the case may be, of this Lease and the other
     Transaction Documents and the consummation of the transactions contemplated
     by the Transaction Documents do not and will not (i) violate any provision
     of any law or any governmental rule or regulation applicable to the Lessee
     or any of its Subsidiaries, the certificate or articles of incorporation or
     bylaws of the Lessee or any of its Subsidiaries or any order, judgment or
     decree of any court or other agency of government binding on the Lessee or
     any of its Subsidiaries, (ii) conflict with in any material respect, result

     both) a material default under any material Contractual Obligation of the
     Lessee or any of its Subsidiaries, (iii) result in or require the creation
     or imposition of any Lien upon any of the properties or assets of the

     behalf of the Lenders), or (iv) require any approval of stockholders or any
     approval or consent of any Person under any Contractual Obligation of the
     Lessee or any of its Subsidiaries, except for such approvals or consents as
     will be obtained on or before the Initial Borrowing Date and disclosed in
     writing to the Lessor and the Lenders.

         (iii) Governmental Consents. The execution, delivery and performance by
     the Lessee and its Subsidiaries, as the case may be, of this Lease and the
     other Transaction Documents and the consummation of the transactions
     contemplated by this Lease and the other Transaction Documents do not and
     will not require any registration with, consent or approval of, or notice
     to, or other action to, with or by, any federal, state or other
     governmental authority or regulatory body that has not been obtained or
     made on or prior to the date required to be obtained or made.

         (iv) Binding Obligation. This Lease and each of the other Transaction
     Documents has been duly executed and delivered by the Lessee and its
     Subsidiaries, as the case may be, to the extent that it is a party thereto,
     and is the legally valid and binding obligation of each such Person,
     enforceable against each such Person in accordance with its respective
     terms, except as may be limited by bankruptcy, insolvency, reorganization,
     moratorium or similar laws relating to or limiting creditors' rights
     generally or by equitable principles relating to enforceability.

         (c) Financial Condition.

                                      -27-
<PAGE>

         (A) The Lessee has heretofore delivered to the Lessor, the Agent and
     the Lenders, the following financial statements and information: the
     audited consolidated and consolidating balance sheets of the Lessee and its
     Subsidiaries as at December 31, 1999, and the related consolidated and
     consolidating statements of income, stockholders' equity and cash flows of
     the Lessee and its Subsidiaries for the fiscal year then ended. All such
     statements were prepared in conformity with GAAP and fairly present the
     financial position (on a consolidated and, where applicable, consolidating
     basis) of the entities described in such financial statements as at the
     respective dates thereof and the results of operations and cash flows (on a
     consolidated and, where applicable, consolidating basis) of the entities
     described therein for each of the periods then ended, subject, in the case
     of any such unaudited financial statements, to changes resulting from audit
     and normal year-end adjustments. Neither the Lessee nor any of its
     Subsidiaries has (and will not, following the Initial Borrowing Date, have)
     any Contingent Obligation, contingent liability or liability for taxes,
     long-term lease or unusual forward or long-term commitment that is not
     reflected in the foregoing financial statements or the notes thereto and
     which in any such case is material in relation to the business, operations,
     properties, assets, condition (financial or otherwise) or prospects of the
     Lessee or any of its Subsidiaries.

         (B) Except as fully disclosed in the financial statements delivered
     pursuant to Section 5(c)(A), there were as of the Initial Borrowing Date no
     liabilities or obligations with respect to the Lessee and its Subsidiaries
     of any nature whatsoever (whether absolute, accrued, contingent or
     otherwise and whether or not due) which, either individually or in
     aggregate, could reasonably be expected to be material to the Lessee and
     its Subsidiaries taken as a whole. As of the Initial Borrowing Date, the
     Lessee does not know of any basis for the assertion against it of any
     liability or obligation of any nature whatsoever that is not fully
     disclosed in the financial statements delivered pursuant to Section 5(c)(A)
     which, either individually or in the aggregate, could reasonably be
     expected to be material to the Lessee and its Subsidiaries taken as a
     whole.

         (d) No Material Adverse Change; No Restricted Junior Payments. Since
December 31, 1999, no event or change has occurred that has caused or evidences,
either in any case or in the aggregate, a Material Adverse Effect. Since
December 31, 1999, neither the Lessee nor any of its Subsidiaries has directly
or indirectly declared, ordered, paid or made, or set apart any sum or property
for, any Restricted Junior Payment or agreed to do so, except as permitted by
subsection 7(e) hereunder.

         (e) Title to Properties, Liens. The Lessee and its Subsidiaries have
(i) good, sufficient and legal title to (in the case of fee interests in real
property), (ii) valid leasehold interests in (in the case of leasehold interests
in real or personal property), or (iii) good title to (in the case of all other
personal property), all of the properties and assets reflected in the financial
statements referred to in subsection 5(c) or in the most recent financial
state-


                                      -28-
<PAGE>



ments delivered pursuant to subsection 6(a), in each case except for assets
disposed of since the date of such financial statements in the ordinary course
of business or as otherwise permitted under subsection 7(g). Except as permitted
by this Lease, all such properties and assets are free and clear of Liens.

         (f) Litigation, Adverse Facts. There are no actions, suits,
proceedings, arbitrations or governmental investigations (whether or not
purportedly on behalf of the Lessee or any of its Subsidiaries) at law or in
equity or in admiralty or before or by any federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, pending or, to the knowledge of the Lessee, threatened
against or affecting the Lessee or any of its Subsidiaries or any property of
the Lessee or any of its Subsidiaries that, individually or in the aggregate,
could reasonably be expected to result in a Material Adverse Effect. Neither the
Lessee nor any of its Subsidiaries is (i) in violation of any applicable laws
that, individually or in the aggregate, could reasonably be expected to result
in a Material Adverse Effect or (ii) subject to or in default with respect to
any final judgments, writs, injunctions, decrees, rules or regulations of any
court or any federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign, that,
individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Effect.

         (g) Payment of Taxes. Except to the extent permitted by subsection
6(c), all tax returns and reports of the Lessee and its Subsidiaries required to
be filed by any of them have been timely filed, and all taxes, assessments, fees
and other governmental charges upon the Lessee and its Subsidiaries and upon
their respective properties, assets, income, businesses and franchises that are
due and payable have been paid when due and payable. The Lessee does not know of
any proposed tax assessment against the Lessee or any of its Subsidiaries that
is not being actively contested by the Lessee or such Subsidiary in good faith
and by appropriate proceedings; provided, that such reserves or other
appropriate provisions, if any, for liabilities for taxes as shall be required
in conformity with GAAP shall have been made or provided in the financial
statements of the Lessee. There are no agreements with respect to taxes between
the Lessee and any tax agency or authority.

         (h) Performance of Agreements. Neither the Lessee nor any of its
Subsidiaries is in default in the performance, observance or fulfillment of any
of the obligations, covenants or conditions contained in any of its Contractual
Obligations, and no condition exists that, with the giving of notice or the
lapse of time or both, would constitute such a default, except where the
consequences, direct or indirect, of such default or defaults, if any, would not
have a Material Adverse Effect.

         (i) Governmental Regulation. Neither the Lessee nor any of its
Subsidiaries is subject to regulation under the Public Utility Holding Company
Act of 1935, the Federal Power Act, the Interstate Commerce Act or the
Investment Company Act of 1940 or under any other federal or state statute or
regulation that may limit its ability to incur Indebted-


                                      -29-
<PAGE>



ness or that may otherwise render all or any portion of its obligations under
the Transaction Documents unenforceable.

         (j) Employee Benefit Plans. The Lessee maintains a qualified retirement
plan under Section 401(k) of the Internal Revenue Code and a medical benefit
plan. The Lessee's 401(k) Plan has no unfunded liabilities in excess of
$10,000,000, and the Lessee is in compliance with all applicable provisions and
requirements of ERISA and the regulations and published interpretations
thereunder with respect to each Employee Benefit Plan and has performed all of
its obligations under such Employee Benefit Plan in all material respects. The
Lessee has no Employee Benefit Plans, other than its 401(k) Plan and the medical
benefit plan. The Lessee has no ERISA Affiliates that sponsor, maintain,
contribute to or are liable with respect to any Employee Benefit Plans.

         (k) Certain Fees. No broker's or finder's fee or commission will be
payable with respect to this Lease or any other Transaction Documents or any of
the transactions contemplated hereby.

         (l) Environmental Protection.

         (i) All facilities and operations of the Lessee and its Subsidiaries
     are, and have been to the best of the Lessee's knowledge, in compliance in
     all material respects with all applicable Environmental Laws.

         (ii) There are no, and have been no, conditions, occurrences, or
     Hazardous Materials Activity, (a) arising at any facilities owned or
     operated by the Lessee or (b) arising in connection with the operations of
     the Lessee or any of its Subsidiaries (including the transportation of
     Hazardous Materials), which conditions, occurrences or Hazardous Materials
     Activity could reasonably be expected to form the basis of an Environmental
     Claim against the Lessee and which, individually or in the aggregate, could
     reasonably be expected to have a Material Adverse Effect.

         (iii) To the best of the Lessee's knowledge, there are no pending or
     threatened Environmental Claims against the Lessee or any of its
     Subsidiaries, and neither the Lessee nor any of its Subsidiaries has
     received any written notices, inquiries, or requests for information with
     respect to any Environmental Claims.

         (m) Employee Matters. There is no strike or work stoppage in existence
or threatened involving the Lessee or any of its Subsidiaries that could
reasonably be expected to have a Material Adverse Effect.

         (n) Solvency. The Lessee and each of its Subsidiaries is and, upon the
incurrence of any obligations by the Lessee under the Leases, will be, after
giving effect to the transactions contemplated hereby, Solvent.

                                      -30-
<PAGE>


         (o) Disclosure. No representation or warranty of the Lessee or any of
its Subsidiaries contained in this Lease or any other Transaction Document or in
any other document, certificate or written statement furnished to the Lessor,
the Agent or the Lenders by or on behalf of the Lessee or any of its
Subsidiaries for use in connection with the transactions contemplated by this
Lease and the other Transaction Documents contains any untrue statement of a
material fact or omits to state a material fact (known to the Lessee, in the
case of any document not furnished by it) necessary in order to make the
statements contained herein or therein not misleading in light of the
circumstances in which the same were made. Any projections and pro forma
financial information contained in such materials are based upon good faith
estimates and assumptions believed by the Lessee to be reasonable at the time
made, it being recognized by the Lessor, the Agent and the Lenders that such
projections as to future events are not to be viewed as facts and that actual
results during the period or periods covered by any such projections may differ
from the projected results. There are no facts known (or which should upon the
reasonable exercise of diligence be known) to the Lessee (other than matters of
a general economic nature) that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect and that have not
been disclosed herein or in such other documents, certificates and statements
furnished to the Lessor, the Agent and the Lenders for use in connection with
the transactions contemplated hereby.

         (p) Registration and Filing; Chief Executive Office.

         (1) Except for the registration of this Lease and the Lease Supplement
     with the FAA and the filing of a financing statement under the Uniform
     Commercial Code in Colorado, it is not necessary or advisable under
     Colorado law or the law of the State of New York in order to ensure the
     validity, effectiveness or enforceability of this Lease or to protect the
     rights of the Lessor in the Aircraft or any part thereof that any other
     instrument be filed, registered or recorded or that any action be taken,
     and, under Colorado law or the law of the State of New York, the rights of
     the Lessor in the Aircraft will have priority in all respects over the
     claims of all creditors of the Lessee other than certain claims by
     landlords of hangars, materialmen, mechanics and warehousemen in respect of
     the Aircraft that have priority under Colorado law.

         (2) The Lessee's chief executive office (as that term is defined in
     Article 9 of the Uniform Commercial Code as in effect in Colorado) is
     located at 538 Commons Drive, Golden, Colorado 80401, and the records of
     the Lessee concerning the Aircraft are maintained at such chief executive
     office or at the operations center at JFK International Airport, Building
     151, Jamaica, New York 11430, where the Lessee normally maintains aircraft
     records.

         SECTION 6. Lessee's Affrimative Covenants.  The Lessee covenants and
agrees that, so long as any amounts under this Lease remain unpaid, the Lessee
shall perform, and will cause each of its Subsidiaries to perform, all covenants
in this Section 6.

                                      -31-
<PAGE>

         (a) Financial Statements and Other Reports. The Lessee will maintain,
and cause each of its Subsidiaries to maintain, a system of accounting
established and administered in accordance with sound business practices to
permit preparation of financial statements in conformity with GAAP. The Lessee
will deliver to the Lessor, the Agent and the Lenders:

         (1) Quarterly Financials: as soon as available and in any event within
     45 days after the end of each fiscal quarter of each fiscal year, (a) the
     consolidated and consolidating balance sheets of the Lessee and its
     Subsidiaries as at the end of such fiscal quarter and the related
     consolidated and consolidating statements of income, stockholders' equity
     and cash flows of the Lessee and its Subsidiaries for such fiscal quarter
     and for the period from the beginning of the then current fiscal year to
     the end of such fiscal quarter, setting forth in each case in comparative
     form the corresponding figures for the corresponding periods of the
     previous fiscal year, all in reasonable detail and certified by the chief
     financial officer of the Lessee that they fairly present the financial
     condition of the Lessee and its Subsidiaries as at the dates indicated and
     the results of their operations and their cash flows for the periods
     indicated, subject to changes resulting from audit and normal year-end
     adjustments, and (b) a narrative report describing the operations of the
     Lessee and its Subsidiaries in the form prepared for presentation to senior
     management for such fiscal quarter and for the period from the beginning of
     the then current fiscal year to the end of such fiscal quarter; provided,
     that delivery of the Lessee's Form 10-Q for such fiscal quarter shall be
     deemed to satisfy the requirements of this subsection 6(a)(1);

         (2) Year-End Financials: as soon as available and in any event within

<PAGE>

         all taxes, assessments and other governmental charges imposed upon it
         or any of its properties or assets or in respect of any of its income,
         businesses or franchises before any penalty, fine or interest accrues
         thereon, and all claims (including, without limitation, claims for
         labor, services, materials and supplies) for sums that have become due
         and payable and that by law have or may become a Lien upon any of its
         properties or assets, prior to the time when any penalty fine or
         interest shall be incurred with respect thereto; provided, that no such
         charge or claim need be paid if being contested in good faith by
         appropriate proceedings promptly instituted and diligently conducted
         and if such reserve or other appropriate provision, if any, with
         respect to any liability for taxes, as shall be required in conformity
         with GAAP shall have been made therefor in the financial statements of
         the Lessee.

                 (ii) The Lessee will not, and will not permit any of its
         Subsidiaries to, file or consent to the filing of any consolidated
         income tax return with any Person (other than any Subsidiary of the
         Lessor or the Lessee and other than the Holding Company and its
         Subsidiaries).

                  (d) Maintenance of Properties; Insurance. The Lessee will, and
will cause its Subsidiaries to, maintain or cause to be maintained in good
repair, working order and condition, ordinary wear and tear excepted, all
material properties used or useful in the business of the Lessee and its
Subsidiaries and from time to time will make or cause to be made all appropriate
repairs, renewals and replacements thereof. The Lessee will maintain or cause to
be maintained, with insurers of recognized responsibility and reputation,
insurance with respect to its properties and business and the properties and
businesses of its Subsidiaries against loss or damage (including, without
limitation, flood insurance, if necessary or advisable) of the kinds customarily
carried or maintained under similar circumstances by corporations engaged in
similar businesses.

                  (e) Inspection; Lender Meeting. The Lessee will, and will
cause its Subsidiaries to, permit any authorized representatives designated by
the Lessor, the Agent or any Lender to visit and inspect any of the properties
of the Lessee or any of its Subsidiaries, including the Aircraft or any part
thereof and any Engine, and its and their financial and accounting records, and,
with the permission of the Lessee, which shall not be unreasonably withheld, to
make copies and take extracts therefrom, and to discuss its and their affairs,
finances and accounts with its and their officers and independent public
accountants (provided, that the Lessee may, if it so chooses, be present at or
participate in any such discussion), all upon reasonable notice and at such
reasonable times during normal business hours and as often as may be reasonably
requested, provided, so long as no Lease Event of Default shall have occurred
and be continuing, that such inspection is not disruptive to the Lessee's
business, as reasonably determined by the Lessee. The cost of any such
inspection shall be borne by the Lessee if an Event of Default has occurred and
is continuing or if the Lessee is thereby shown

                                      -37-
<PAGE>

to be in material breach of any of its obligations hereunder, and otherwise by
the party making the inspection. Neither the Lessor, the Agent nor any Lender
shall have any obligation to make any inspection. Without limiting the
foregoing, the Lessor (or its authorized representative) may attend any Airframe
maintenance visit, APU shop visit, landing gear shop visit or Engine shop visit.
The Lessee shall provide the Lessor not less than twenty days' prior written
notice of any such scheduled visit; provided, that if a scheduled visit is to
occur less than twenty days after the scheduling thereof, the Lessee shall
provide written notice of such scheduled visit promptly upon the scheduling
thereof. Without in any way limiting the foregoing, the Lessee will, upon the
request of the Lessor or the Agent, participate in a meeting of the Agent and
the Lenders once during each fiscal year to be held at the Lessee's corporate
offices (or such other location as may be agreed to by the Lessee, the Lessor
and the Agent) at such time as may be agreed to by the Lessee, the Lessor and
the Agent.

                  (f) Compliance with Laws, etc. The Lessee will, and will cause
its Subsidiaries to, comply with the requirements of all applicable laws, rules,
regulations and orders of any governmental authority (including, without
limitation, Environmental Laws), noncompliance with which could reasonably be
expected to cause a Material Adverse Effect or prevent the Lessee from
performing its obligations hereunder. The Lessee shall not conduct, and shall
not permit the conduct of, any Hazardous Materials Activity at any facility or
at any other location that could reasonably be expected to form the basis of an
Environmental Claim against the Lessee and that could reasonably be expected to
have a Material Adverse Effect.

                  (g) Lessee's Remedial Action Regarding Hazardous Materials.
The Lessee will promptly take, and will cause each of its Subsidiaries promptly
to take, any and all necessary remedial action in connection with the presence,
storage, use, disposal, transportation or Release of any Hazardous Materials on,
under or about any facility in order to comply with all applicable Environmental
Laws and Governmental Authorizations. In the event that the Lessee or any of its
Subsidiaries undertakes any remedial action with respect to any Hazardous
Materials on, under or about any facility, the Lessee or such Subsidiary will
conduct and complete such remedial action in compliance with all applicable
Environmental Laws, and in accordance with the policies, orders and directives
of all federal, state and local governmental authorities except when, and only
to the extent that, the Lessee's or such Subsidiary's liability for such
presence, storage, use, disposal, transportation or discharge of any Hazardous
Materials is being contested in good faith by the Lessee or such Subsidiary.
Notwithstanding anything to the contrary contained in this Lease, the Lessee and
its Subsidiaries may engage in the transportation of Hazardous Materials in the
ordinary course of business so long as such is conducted in compliance with all
applicable Environmental Laws, and all other applicable laws, policies, orders,
directives and regulations.

                  (h) Employee Benefit Plans. The Lessee will not establish or
permit to be established any Employee Benefit Plans for the Lessee or any of its
employees and will not permit any ERISA Affiliate to establish any Employee
Benefit Plan that, in either case, could



                                      -38-
<PAGE>

reasonably be expected to result in a liability for the Lessee, under Title IV
of ERISA or the minimum funding standards of Part 3 of Subtitle B of Title I of
ERISA, in excess of $20 million.

                  (i) Corporate Separateness. The Lessee will take all such
action as is necessary to keep its operations separate and apart from those of
the Holding Company or any of its Affiliates, including, without limitation,
ensuring that all customary corporate formalities, including the maintenance of
separate corporate records and documents and holding regular meetings, are
followed. Any financial statements distributed to any creditors of the Lessee
shall clearly establish the corporate separateness of the Lessee from the
Holding Company and each of the Holding Company's other Subsidiaries. The Lessee
shall not take any action or conduct its affairs in a manner that is likely to
result in the corporate existence of the Lessee on the one hand and of the
Holding Company or any Subsidiary of the Holding Company on the other hand being
disregarded, or in the assets and liabilities of the Holding Company or any
Subsidiary of the Holding Company being substantively consolidated with those of
the Lessee in a bankruptcy, reorganization or other insolvency proceeding.

                  SECTION 7. Lessee's Negative Covenants. The Lessee covenants
and agrees that, so long as any amounts remain owing under this Lease, the
Lessee shall perform, and shall cause each of its Subsidiaries to perform, all
covenants in this Section 7.

                  (a) Indebtedness. The Lessee shall not, and shall not permit
any of its Subsidiaries, directly or indirectly, to create, incur, assume or
guaranty, or otherwise become or remain directly or indirectly liable with
respect to, any Indebtedness, except that:

                  (1) the Lessee may become and remain liable with respect to
         the obligations under the Amended Aircraft Credit Facility;

                  (2) the Lessee and its Subsidiaries may become and remain
         liable with respect to Contingent Obligations permitted by subsection
         7(d) and, upon any matured obligations actually arising pursuant
         thereto, the Indebtedness corresponding to the Contingent Obligations
         so extinguished;

                  (3) the Lessee and its Subsidiaries may become and remain
         liable with respect to Indebtedness in respect of Capital Leases;
         provided, that such Capital Leases are permitted under the terms of
         subsection 7(i);

                  (4) the Lessee and its Subsidiaries, as applicable, may remain
         liable with respect to Indebtedness described in Schedule 7(a) (4)
         annexed hereto;

                  (5) the Lessee may become and remain liable with respect to
         transaction in which Permitted Extension Indebtedness is incurred with
         respect to any Financed Aircraft, the

                                      -39-
<PAGE>

         cash proceeds from such Permitted Extension Indebtedness are sufficient
         to repay in full the Indebtedness associated with such Financed
         Aircraft;

                  (6) so long as no Default or Lease Event of Default shall have
         occurred and be continuing or would result therefrom and the Lessee
         delivers an Officers' Certificate to the Lessor, the Agent and the
         Lenders, in form and substance reasonably satisfactory to the Lessor

of, in one transaction or a series of transactions, all or any part of its
business, property or fixed assets, whether now owned or hereafter acquired, or
acquire by purchase or otherwise all or any portion of the business, property or
fixed assets of, or stock or other evidence of beneficial ownership of, any
Person or any division or line of business of any Person, except that:

                  (1) any Subsidiary of the Lessee may be merged with or into
         the Lessee or any wholly-owned Subsidiary of the Lessee, or be
         liquidated, wound up or dissolved, or all or any part of its business,
         property or assets may be conveyed, sold, leased, transferred or
         otherwise disposed of, in one transaction or a series of transactions,
         to the Lessee or any such wholly-owned Subsidiary of the Lessee;
         provided, that, in the case of such a merger, the Lessee or such
         wholly-owned Subsidiary shall be the continuing or surviving
         corporation;

                  (2) the Lessee and its Subsidiaries may sell or otherwise
         dispose of assets in transactions that do not constitute Asset Sales;

         an amount at least equal to the fair market value thereof;

                  (3) subject to subsection 7(m), the Lessee and its

         another Person or all or substantially all of the assets of a division
         or line of business of another Person, provided that (a) the
         acquisition primarily involves the acquisition of assets to be used in
         the business of the Lessee, (b) if such acquisition is structured as a
         merger or a stock or other equity acquisition, then either (i) the
         Person so acquired becomes a wholly-owned Subsidiary of the Lessee or
         (ii) such Person is merged with and into the Lessee or a wholly-owned
         Subsidiary of the Lessee (with the Lessee or such wholly-owned
         Subsidiary being the surviving corporation of such merger), (c) if such
         acquisi-

                                      -48-

         tion is structured as an asset acquisition, then such assets are
         acquired either by the Lessee directly or by a wholly-owned Subsidiary
         of the Lessee, (d) immediately before and after giving effect thereto,
         no Default or Lease Event of Default shall have occurred and be
         continuing, (e) immediately after giving effect to the acquisition, the
         Lessee shall be in compliance on a Pro Forma Basis with the financial
         covenants in subsection 7(f) and such compliance shall be evidenced by

         and the Agent shall have reviewed and be reasonably satisfied with the
         nature and amount of all contingent liabilities or other liabilities
         not on the balance sheet of the Lessee assumed in connection with such
         acquisition and (g) the aggregate amount of cash payments made in
         connection with all such acquisitions other than with the proceeds from
         sales or issuances of equity by the Lessee does not exceed
         $100,000,000;

                  (6) the Lessee and its Subsidiaries may make Consolidated
         Capital Expenditures in connection with the purchase of up to twelve
         Eligible Aircraft during each fiscal year, such number of Eligible
         Aircraft permitted during any fiscal year to be increased by any number
         of Eligible Aircraft permitted to be purchased, but not purchased,
         during the previous fiscal year (but in no event shall any such number
         of Eligible Aircraft once carried forward to the next fiscal year be
         carried forward to any fiscal year thereafter) together with
         Consolidated Capital Expenditures with respect to the acquisition, in
         the normal course of business, of spare parts and spare engines
         associated with such Eligible Aircraft;

                  (7) the Lessee and its Subsidiaries may make Consolidated
         Capital Expenditures with respect to maintenance of aircraft in the

                  (8) the Lessee and its Subsidiaries may make other
         Consolidated Capital Expenditures not in excess of $10 million during
         any fiscal year; provided, that any amount of such other Consolidated
         Capital Expenditures permitted, but not made, in any fiscal year may be
         carried forward to and made during the immediately succeeding fiscal
         year (but no amount once carried forward to the next fiscal year may be
         carried forward to any fiscal year thereafter);

                  (9) the Lessee shall be permitted to dispose of or acquire
         assets pursuant to the consolidation and relocation of its offices and
         operations to Colorado; provided, that the aggregate consideration paid

                                      -49-
<PAGE>

                  (h) Amendments of Material Agreements. The Lessee shall not
permit (i) its certificate or articles of incorporation or bylaws to be amended
or otherwise modified in any manner that could reasonably be expected to have a
Material Adverse Effect or (ii) any Material Agreement to be amended or
otherwise modified in any manner with respect to any provision providing
material representations and warranties to the Lessee, indemnification rights to
the Lessee, or limiting the Lessee's remedies or rights upon the other party to
such agreements failing to perform.

                  (i) Restriction on Leases. The Lessee shall not, and shall not
permit any of its Subsidiaries to, become liable in any way, whether directly or
by assignment or as a guarantor or other surety, for the obligations of the
lessee under any lease, whether an Operating Lease or a Capital Lease (other
than intercompany leases between the Lessee and its wholly-owned Subsidiaries,
including the Lessor); provided, however, that the Lessee may become so
obligated to the extent that, and only to the extent that, immediately after
giving effect to the incurrence of liability with respect to such lease, the
Consolidated Rental Payments at the time in effect during the then current
fiscal year do not exceed $35 million plus the amount of Consolidated Rental
Payments made during such fiscal year in respect of up to eight 747-400F
aircraft subject to Operating Leases as of the Initial Borrowing Date plus the
amount of Consolidated Rental Payments in respect of up to two 747-400F aircraft
per year, subject to the agreement dated June 9, 1997, between the Lessee and
The Boeing Company regarding the purchase of twelve new 747-400F aircraft and
the option to purchase eight additional new 747-400F aircraft, plus an amount,
not to exceed $15 million during any fiscal year, equal to Consolidated Rental
Payments incurred in connection with sale and leaseback transactions described
in subsection 7(j), plus Consolidated Rental Payments assumed pursuant to
acquisitions permitted under subsection 7(g)(5).

                  (j) Sales and Lease-Backs. The Lessee shall not, and shall not
permit any of its Subsidiaries to, directly or indirectly, become or remain
liable as lessee or as a guarantor or other surety with respect to any lease,
whether an Operating Lease or a Capital Lease, of any property (whether real,
personal or mixed), whether now owned or hereafter acquired, (i) that the Lessee
or any of its Subsidiaries has sold or transferred or is to sell or transfer to
any other Person (other than the Lessee or any of its Subsidiaries) or (ii) that
the Lessee or any of its Subsidiaries intends to use for substantially the same
purpose as any other property that has been or is to be sold or transferred by
the Lessee or any of its Subsidiaries to any Person (other than the Lessee or
any of its Subsidiaries) in connection with such lease; provided, that the
Lessee and its Subsidiaries may become and remain liable as lessee, guarantor or
other surety with respect to any such lease if and to the extent that the Lessee
or any of its Subsidiaries would be permitted to enter into, and remain liable
under, such lease under subsection 7(i).

                  (k) Transactions with Shareholders and Affiliates. The Lessee
shall not, and shall not permit any of its Subsidiaries to, directly or
indirectly, enter into or permit to

                                      -50-
<PAGE>

exist any transaction (including, without limitation, the purchase, sale, lease
or exchange of any property or the rendering of any service) with any holder of
10% or more of any class of equity Securities of the Lessee or with any
Affiliate of the Lessee or of any such holder, on terms that are less favorable
to the Lessee or that Subsidiary, as the case may be, than those that might be
obtained at the time from Persons who are not such holders or Affiliates;
provided, that the foregoing restriction shall not apply to (i) reasonable and
customary fees paid to and indemnification of members of the Boards of Directors
of the Lessee and its Subsidiaries, (ii) reasonable and customary salaries,
bonuses and other compensation paid to and indemnification of employees of the
Lessee or any of its Subsidiaries in accordance with past practice or approved
by the compensation committee of the Lessee, (iii) performance by the Lessee of
its obligations under and in accordance with the Services Agreement or (iv) the
Holding Company Reorganization.

                  (l) Disposal of Subsidiary Stock.  The Lessee shall not:

                  (1) directly or indirectly sell, assign, pledge or otherwise
         encumber or dispose of any shares of capital stock or other equity
         Securities of any of its Subsidiaries, except to qualify directors if
         required by applicable law or to a wholly-owned Subsidiary of the
         Lessee; or

                  (2) permit any of its Subsidiaries directly or indirectly to
         sell, assign, pledge or otherwise encumber or dispose of any shares of
         capital stock or other equity Securities of any of its Subsidiaries
         (including such Subsidiary), except to the Lessee, another wholly-owned
         Subsidiary of the Lessee, or to qualify directors if required by
         applicable law.

                  Notwithstanding the foregoing, the Lessor shall be permitted
to issue preferred stock in an amount not to exceed $100,000 to a third party.

                  (m) Conduct of Business. From and after the Initial Borrowing
Date, the Lessee shall not, and shall not permit any of its Subsidiaries to,
engage in any business other than the businesses engaged in by the Lessee and
its Subsidiaries on the Initial Borrowing Date and similar or related
businesses.

                  (n) Change of Chief Executive Office. The Lessee shall not,
and shall not permit any of its Subsidiaries to, change its chief executive
office without giving 30 days' prior written notice to the Lessor and the Agent.

                  SECTION 8. Return of the Aircraft.

                  (a) Condition Upon Return. Unless the Aircraft has been sold
pursuant to Section 21, if at any time the Lessee shall return the Aircraft to
the Lessor hereunder, the Lessee, at its own expense, will return the Aircraft
to the Lessor at a location specified by the

                                      -51-
<PAGE>

Lessor to the Lessee in writing. At the time of such return, (i) the Lessee will
cause the Aircraft to be in compliance with the maintenance covenants contained
in this Lease and (ii) the Airframe will be fully equipped with the Engines
installed thereon.

                  At the time of such return, such Airframe and Engines (A)
shall have an airworthiness certificate from the Federal Aviation Administration
and shall be in full compliance with the provisions of Federal Aviation
Regulations, Part 121 (or successor regulation), and shall be in material
compliance with all applicable FAA noise, corrosion, environmental and aging
aircraft requirements, (B) shall be free and clear of all Liens and (C) in the
case of the Aircraft, shall be in a full freighter configuration and in as good
condition as when originally delivered to the Lessee, ordinary wear and tear
excepted, and otherwise in the condition required to be maintained under the
Lessee's FAA-approved maintenance plan; and in all such cases the Aircraft shall
not have been discriminated against as compared to other aircraft owned or
leased by the Lessee whether by reason of its leased status or otherwise in
maintenance, use, operation or in any other manner whatsoever.

                  (b) Overhaul and Repair. The Airframe, Engines and all Parts
shall have been, and shall be properly documented to have been, repaired or
overhauled by certified repair stations acceptable to the FAA.

                  (c) Repairs. The Lessee shall ensure that all repairs
performed since the Initial Borrowing Date on the Aircraft are eligible to
receive approval by the FAA (or its designee), if so required. All such repairs
shall be accompanied by all data and documentation necessary to substantiate
their certification, approval and methods of compliance, as required.

                  (d) Modifications. All modifications performed since the
Initial Borrowing Date that deviate from the certified configuration and that
are still in existence on the Aircraft shall have approval or certification by
the FAA (or its designee) or certification if required. All such modifications
shall be accompanied by complete data and documentation necessary to
substantiate their certification and approval and methods of compliance.

                  (e) Airworthiness Directives. All FAA Airworthiness Directives
and amendments or changes to the Federal Aviation Regulations applicable to the
Airframe, Engines (or Acceptable Alternate Engines) or Parts, as well as all
mandatory service bulletins applicable to any of the foregoing, shall have been
accomplished by terminating action in compliance with the issuing agency's or
the manufacturer's specific instructions, as the case may be, taking into
account, any waiver, deferral or deviation from such directives, regulations or
bulletins.

                  (f) Return of the Engines. In the event that an Acceptable
Alternate Engine shall be delivered with the returned Airframe, the Lessee,
concurrently with such delivery, will, at no cost to the Lessor, furnish, or
cause to be furnished, to the Lessor a full warranty (as to title) bill of sale
with respect to each such Acceptable Alternate Engine, in form



                                      -52-
<PAGE>

and substance reasonably satisfactory to the Lessor (together with an opinion of
counsel to the effect that such full warranty bill of sale has been duly
authorized and delivered and is enforceable in accordance with its terms and
that such Acceptable Alternate Engines are free and clear of all Liens) against
receipt from the Lessor of a bill of sale evidencing the transfer, without
recourse or warranty by the Lessor to the Lessee or its designee of all of the
Lessor's right, title and interest in and to any Engine not installed on the
Airframe at the time of the return of the Airframe.

                  (g) Deferred Maintenance. There shall be no open, outstanding
or deferred maintenance items, scheduled or unscheduled, against the Aircraft
including those identified in pre-delivery inspections or test flights.

                  (h) Corrosion Treatment. At the time of return, the Aircraft
shall have been maintained by cleaning and treating all mild and moderate
corrosion and correcting of all severe or exfoliate corrosion in accordance with
the Lessee's approved maintenance program or manufacturer's structural repair
manual.

                  (i) Manuals. Upon the return of the Aircraft upon any
termination of this Lease, the Lessee shall deliver or cause to be delivered to
the Lessor all logs, manuals and data and maintenance, inspection, modification
and overhaul records and similar records required to be maintained with respect
to the Aircraft and Parts under FAA rules and the Aircraft maintenance program
(the "Technical Records"). If any such logs, manuals, records or other data are
missing, incomplete or otherwise not in accordance with FAA standards applicable
to the Lessee, the Lessee shall re-accomplish the maintenance tasks necessary to
produce such records in accordance with its approved maintenance program prior
to delivery of the Aircraft or otherwise perform all necessary acts (without
regard to any applicable waivers or deferrals) to obtain such records in a
manner satisfactory to the FAA and the Lessor.

                  (j) Storage Upon Return. If, at least 15 days prior to
termination of this Lease at the end of the Term or pursuant to Section 17, the
Lessee receives from the Lessor a written request for storage of the Aircraft
upon its return hereunder, the Lessee will provide the Lessor, or cause the
Lessor to be provided, with storage facilities for the Aircraft at the Lessee's
risk and at the Lessee's expense for a period not exceeding 30 days, and
thereafter at the Lessor's risk and at the Lessor's cost for insurance,
maintenance and the Lessee's out-of-pocket expenses for such storage for a
period not exceeding 90 days (provided, that if such termination occurs as a
result of a Lease Event of Default hereunder, such storage shall be at the cost
of the Lessee), commencing on the date when the Aircraft is returned
substantially in the condition required under this Section 8, at a location in
the continental United States selected by the Lessee and used by the Lessee as a
location for the long-term parking or storage of aircraft.

                  (k) Severable Parts. At any time that the Aircraft is to be
returned to the Lessor, the Lessee shall, at the Lessor's request, advise the
Lessor of the nature and condition



                                      -53-
<PAGE>

of all severable nonproprietary Parts (other than Parts otherwise required by
Sections 10 or 11 to be maintained on the Aircraft) owned by the Lessee have
been used by the Lessee during the prior six months and that the Lessee has or
intends to remove from the Aircraft in accordance with Section 11 hereof. The
Lessor may, at its option, upon 30 days notice to the Lessee, purchase any or
all of such nonproprietary Parts from the Lessee upon the expiration of the Term
at their fair market value.

                  (l) Survival. The obligations of the Lessee to comply with the
terms of this Section 8 shall survive the expiration or other termination of
this Lease.

                  (m) Deregistration and Export. At such time as the Lessee is
obligated to redeliver the Aircraft to the Lessor pursuant to this Lease, the
Lessee shall at its expense upon the request of the Lessor:

                  (i) promptly take all such steps (not including procuring the
         discharge of any Lessor's Liens) as may be necessary to cancel the
         existing registration of the Aircraft (subject to the Lessor giving, or
         procuring that any mortgagee of the Aircraft gives, such notices and/or
         required consents to the cancellation of such registration) and obtain
         and deliver to the Lessor all certificates relating to the Aircraft
         required by applicable law on any transfer of or alteration to the
         registration thereof;

                 (ii) provide to the Lessor all assistance as the Lessor may
         reasonably request so as to enable the Lessor to obtain any documents
         (including, without limitation, any export certificate of
         airworthiness) required by applicable law in relation to the export of
         the Aircraft from the state of registration or such other country in
         which the Aircraft is for the time being located and shall re-assign or
         otherwise confirm to the Lessor the benefit of any indemnities or
         warranties available to the Lessee from the manufacturer or any other
         supplier or manufacturer of the Airframe, Engines or any Part; and

                (iii) provide to the Lessor such assistance with respect to
         information and documentation as the Lessor may reasonably require so
         as to enable the Aircraft to be registered and certified as to
         airworthiness under any applicable laws and/or regulations of any
         country other than the state of registration; provided, that the Lessor
         shall reimburse, the Lessee for its reasonable out-of-pocket expenses
         incurred in providing such assistance.

                  SECTION 9. Liens. The Lessee will not directly or indirectly
create, incur, assume or suffer to exist any Lien, on or with respect to the
Aircraft, title thereto or any interest therein, except the lien of the Aircraft
Chattel Mortgage and Permitted Encumbrances. The Lessee will promptly, at its
own expense, take such action as may be necessary to duly discharge any such
Lien not excepted above if the same shall arise at any time.

                  SECTION 10. Registration, Maintenance and Operation;
Possession and Subleases; Insignia.

                  (a) Maintenance and Operation. The Lessee, at its own cost and
expense, until the expiration or earlier termination of this Lease, (i) will be
a "citizen of the United States" as defined in Section 40102(15) of Title 49 of
the United States Code and will be an air carrier certificated under Sections
401 and 609 of the Federal Aviation Act and hold all necessary air carrier
operating certificates; (ii) will cause ownership of the Aircraft to be duly
registered and remain duly registered with the FAA in the name of the Lessor in
accordance with the Federal Aviation Act and otherwise registered under all
applicable laws of the United States so as to be eligible to operate in
commercial air service under the Federal Aviation Act; and (iii) will service,
repair, inspect, test, maintain and overhaul the Airframe and each Engine,
install replacement equipment and parts on the Airframe and each Engine and
maintain the Technical Records (A) so as to keep the Airframe and each Engine in
such operating condition as may be required to permit the Airframe and each
Engine to be utilized in commercial operations in the United States, (B) so as
to enable the airworthiness certification of the Airframe to be maintained in
good standing at all times under the Federal Aviation Act, except when aircraft
of the same type, model or series as the Airframe (powered by engines of the
same type as those with which the Airframe shall be equipped at the time of
grounding) registered in the United States have been grounded by the FAA;
provided, however, that if, following its issuance, the United States FAA
airworthiness certificate of the Aircraft shall be withdrawn, then, subject to
the provisions of Section 13 hereof, so long as the Lessee is diligently taking
or causing to be taken all necessary action promptly to correct the condition
that caused such withdrawal, no Lease Event of Default shall arise from such
withdrawal, (C) in accordance with the Lessee's FAA-approved maintenance,
inspection and maintenance control programs, and in the same manner and with the
same care used by the Lessee with respect to the same or similar aircraft and
engines owned or operated by the Lessee so as to keep the same in as good
operating condition as when originally leased hereunder, ordinary wear and tear
excepted, which practices shall at all times be at or above the standard of the
industry in the United States for prudent maintenance of similar equipment, (D)
in such manner as may be necessary to maintain in full force all warranties of
the manufacturers thereof, and (E) to enable the Lessee to deliver the Aircraft
to the Lessor in accordance with Section 8. The Lessee shall maintain all
records, logs and other materials that may be required to permit the Airframe
and each Engine to be so utilized.

                  The Lessee will comply in all material respects with all
airworthiness directives, mandatory notes or modifications or similar
requirements affecting the same (including those issued by the manufacturer or
supplier) in such condition so as to comply with this Lease and the rules and
regulations of the FAA from time to time in force and applicable to the Aircraft
and Engines. Neither the Airframe nor any Engine will be maintained, used or
operated in violation of any law or any rule, regulation or order of any
government or governmental authority having jurisdiction (domestic or foreign),
or in violation of any airworthi-

                                      -55-
<PAGE>

ness certificate, license or registration relating to the Airframe or such
Engine issued by any such authority, and in the event that such laws, rules,
regulations or orders require alteration of the Airframe or any Engine, the
Lessee, at its own cost and expense, will conform thereto or obtain conformance
therewith and will maintain the same in proper operating condition under such
laws, rules, regulations and orders, provided, however, that the Lessee may, in
good faith (after having delivered to the Lessor and the Agent an Officers'
Certificate stating the facts with respect thereto), contest the validity or
application of any such law, rule, regulation or order in any reasonable manner
that does not, in the Lessor's and the Agent's opinion (in their sole
discretion), adversely affect the interests of the Lessor, the Agent or any
Lender.

                  The Lessee covenants and agrees with the Lessor that, the
better to ensure the availability of the benefits of Section 1110 of the
Bankruptcy Code, the Lessee shall not object to any motion, petition or
application filed by the Lessor with any bankruptcy court having jurisdiction
over the Lessee, solely as to the portion thereof that seeks, and to the extent
that such motion, petition or application seeks, a determination that such
Section 1110 of the Bankruptcy Code applies to the lease of the Aircraft
hereunder. In the event that Section 1110 is amended, or if it is repealed and
another statute is enacted in lieu thereof, the Lessor and the Lessee (at the
Lessee's expense) agree to amend this Lease and take such other action not
inconsistent with this Lease as the Lessor reasonably deems necessary so as to
afford to the Lessor the rights and benefits as such amended or substituted
statute confers upon owners, lessors and conditional vendors of aircraft
similarly situated to the Lessor.

                  The Lessee will not operate, use or locate the Airframe or any
Engine, (I) in any area in which any insurance required to be maintained
pursuant to Section 14 shall not be at the time in full force and effect, or in
any area excluded from coverage by an insurance policy in effect with respect to
the Airframe or such Engine, except in the case of a requisition for use by the
United States of America, and then only if the Lessee obtains indemnity in lieu
of such insurance from the United States of America against the risks and in the
amounts required by said Section covering such area, or (II) in any recognized
or threatened area of hostilities unless the Airframe or such Engine is operated
or used under contract with the Government of the United States of America under
which contract that Government assumes liabilities for any damages, loss,
destruction or failure to return possession of the Airframe or such Engine at
the end of the term of such contract and for injury to persons or damage to
property of others.

                  The Lessee shall not use the Aircraft nor suffer it to be used
in any manner or for any purpose excepted from any of the insurance on or in
respect of the Aircraft or for the purpose of carriage of goods of any
description excepted from such insurance nor do, or permit to be done, anything
which, or omit to do anything the omission of which, may invalidate any of such
insurance.

                  (b) Possession. The Lessee will not, without the prior written
consent of the Agent and the Lessor, sell, assign, lease or otherwise in any
manner deliver, transfer or



                                      -56-
<PAGE>

relinquish possession or control of, or transfer the right, title or interest of
the Lessee in, the Airframe or any Engine except that, unless a Default or Lease
Event of Default shall have occurred and be continuing, the Lessee may, without
the prior written consent of the Agent and the Lessor, take the following
actions so long as the actions to be taken shall not deprive the Agent of the
first priority Lien under the Aircraft Chattel Mortgage in the assets subject
thereto and so long as the actions to be taken shall not deprive the Lessor of
the protections of Section 1110 of the Bankruptcy Code with respect to the
Aircraft and shall not deprive the Agent of the protections of Section 1110 of
the Bankruptcy Code with respect to the Aircraft as assignee of the Lessee's
rights under this Lease pursuant to the Aircraft Chattel Mortgage:

                  (i) transfer possession of the Airframe or any Engine other
         than by lease to the United States of America or any instrumentality
         thereof pursuant to the Civil Reserve Air Fleet Program (as
         administered pursuant to Executive Order 12656, or any substitute
         order) or any similar or substitute programs;

                 (ii) transfer possession of the Airframe or any Engine to the
         manufacturer thereof for testing or other similar purposes or any other
         organization for service, repairs, maintenance or overhaul or, to the
         extent permitted by Section 11 hereof, for alterations or
         modifications;

                (iii) subject any Engine to normal interchange or pooling
         agreements or arrangements of the type customary in the United States
         airline industry and entered into by the Lessee in the ordinary course
         of business that do not contemplate or require the transfer of title
         to, use for the remainder of its useful life, or registration of the
         Airframe or title to or use for the remainder of its useful life of
         such Engine; provided, however, that if the Lessee's title to or use
         for the remainder of its useful life of the Airframe or any Engine
         shall be divested under any such agreement or arrangement, such
         divesture shall be deemed to be an Event of Loss with respect to the
         Airframe or such Engine and the Lessee shall comply with Section 13 in
         respect thereof;

                 (iv) install an Engine on an airframe that is owned by the
         Lessee free and clear of all Liens except (A) those permitted under
         clauses (i) or (ii) of the definition of Permitted Encumbrances in the
         Credit Agreement, (B) those that apply only to the engines (other than
         the Engines), appliances, parts, instruments, appurtenances,
         accessories, furnishings and other equipment (other than Parts)
         installed on such airframe (but not to the airframe as an entirety),
         and (C) the rights of any Domestic Air Carrier, under normal
         interchange agreements that are customary in the airline industry and
         do not contemplate or require the transfer of title to such airframe or
         the engines installed thereon;

                  (v) install an Engine on an airframe leased to the Lessee or
         owned by the Lessee subject to a conditional sale or other security
         agreement, provided that: (A) such airframe is free and clear of all
         Liens, except for the rights of the parties to the



                                      -57-
<PAGE>

         lease or conditional sale or other security agreement covering such
         airframe and except for Liens of the type permitted by clause (iv)
         above; and (B) the Agent and the Lessor shall have received from the
         lessor, conditional vendor or secured party and each of the purchasers,
         mortgagees and encumbrancers of such lessor, conditional vendor or
         secured party of such airframe a written agreement (which may be the
         lease, conditional sale agreement or mortgage covering such airframe),
         whereby such lessor, conditional vendor or secured party and each of
         the purchasers, mortgagees and encumbrancers of such lessor,
         conditional vendor or secured party expressly and effectively
         agrees that neither it nor its successors and assigns will acquire
         or claim any right, title or interest in any Engine by reason of
         such Engine being installed on such airframe at any time when such
         Engine is subject to the Aircraft Chattel Mortgage;

                 (vi) install an Engine on an airframe owned by the Lessee,
         leased by the Lessee or owned by the Lessee subject to a conditional
         sale or other security agreement under circumstances where neither
         clause (iv) nor clause (v) above is applicable; provided, that any
         divesture of title to such Engine resulting from such installation
         shall be deemed to be an Event of Loss with respect to such Engine and
         the Lessee shall comply with Section 13 in respect thereof;

                (vii) enter into an ACMI Contract or wet lease for the Airframe
         and the Engines or engines installed thereon with any third party
         pursuant to which the Lessee has operational control of the Airframe
         and any Engines installed thereon, such operation to be performed
         solely by individuals under the operational control of the Lessee
         possessing all current certificates and licenses that would be required
         under the applicable laws of the United States for the performance by
         such employees of similar functions within the United States; provided,
         that the Lessee's obligations hereunder shall continue in full force
         and effect notwithstanding any such ACMI Contract or wet lease; and

               (viii) sell the Aircraft in accordance with Section 6.6(ii) of
         the Credit Agreement or replace the Airframe or any Engine in
         accordance with Section 9.21 of the Credit Agreement;

provided, however, that the rights of any transferee (other than with respect to
any transactions referred to in paragraph (viii) above) who receives possession
of the Airframe or any Engine permitted by the terms hereof shall be made
subject and subordinate to, and any lease permitted by this Section 10(b) shall
be made expressly subject and subordinate to, the Lease and the lien and
security interest of the Aircraft Chattel Mortgage and all of the Agent's rights
thereunder and the Lessee shall remain primarily liable hereunder for the
performance of all the terms of the Lease to the same extent as if such transfer
had not occurred, and any such instrument of transfer shall include appropriate
provisions for the maintenance and insurance of the Airframe or such Engine, and
any such instrument of transfer shall expressly prohibit any further transfer of
the Airframe or such Engine or any assignment of the rights thereunder;



                                      -58-
<PAGE>

and provided further, that no such lease, pooling arrangement or other transfer
or relinquishment of the possession of the Airframe or any Engine shall in any
way discharge or diminish any of the Lessee's obligations to the Lessor
hereunder.

                  (c) Insignia. The Lessee shall, at its own cost and expense,
cause the Airframe and each Engine to be legibly marked (in a reasonably
prominent location, which in the case of the Airframe shall be adjacent to the
airworthiness certificate) with such a plate, disk, or other marking of
customary size, and bearing the legend "Owned by Atlas Freighter Leasing III,
Inc., and Mortgaged to Bankers Trust Company, as the Agent" or such other
legend, as shall in the opinion of the Lessor and the Agent be appropriate or
desirable to evidence the fact that it is subject to the ownership of the Lessor
and the lien and security interest created by the Aircraft Chattel Mortgage. The
Lessee shall not remove or deface, or permit to be removed or defaced, any such
plate, disk, or other marking or the identifying manufacturer's serial number,
and, in the event of such removal or defacement, shall promptly cause such
plate, disk, or other marking or serial number to be promptly replaced. Except
as provided above, the Lessee shall not allow the name of any person,
association or corporation to be placed on the Airframe or any Engine as a
designation that might be interpreted as a claim of ownership or of any security
interest therein, except that the Lessee or any permitted lessee may place its
customary colors and insignia or the insignia of the manufacturer on the
Airframe or any Engine.

                  (d) Holding Out. The Lessee agrees that it will not at any
time represent or hold out the Lessor, the Agent, any Lender or any Affiliate of
any of them (and will use its best efforts to ensure that none of the Lessor,
the Agent, any Lender or any Affiliate of any of them is not at any time
represented or held out) as being in any way connected or associated with any
operation of the Airframe, any Engine or any Part or any other operations or
carriage undertaken by the Lessee.

                  (e) No Pledging of Credit. The Lessee is not authorized to,
and agrees that it will not purport to, pledge the credit of the Lessor, any
Lender or the Agent for any maintenance, service, repairs, or overhauls of,
modifications to, or changes or alterations in, the Airframe, any Engine or any
Part, or for any other purpose whatsoever.

                  (f) Title. Title to the Aircraft shall remain vested in the
Lessor subject to the Aircraft Chattel Mortgage and any assignments, charges or
other disposals that the Lessor may make in accordance with this Lease. The
Lessee shall not do or knowingly permit to be done anything that would
jeopardize the rights of the Lessor as owner of, or the rights of any Lender in,
the Aircraft and shall cause to be taken all actions necessary or reasonably
requested by the Lessor to prevent the rights of the Lessor and the Lenders in
the Aircraft from being jeopardized. The Lessee shall not hold itself out to any
third party as the owner of the Aircraft or any part of it, and when any third
party inquires as to ownership of the Aircraft or any Engine or any part
thereof, it will make clear to such third party that title to the same is held
by the Lessor and that the Aircraft is mortgaged to the Lenders. Without
limiting the




                                      -59-
<PAGE>

foregoing, if at any time subsequent to the initial registration of the
Aircraft, any filing, recording or act is necessary or reasonably requested by
the Lessor to perfect, protect and preserve the rights and interests of the
Lessor in the Aircraft and the rights and interests of any Lender under the
Aircraft Chattel Mortgage, the Lessee, at its own cost and expense, will procure
that such filings, recordings and acts are done pursuant to applicable laws. At
the reasonable request of the Lessor, the Lessee shall furnish to the Lessor an
opinion of counsel or other evidence satisfactory to the Lessor of each such
filing, recordation and act. The Lessor will reimburse the Lessee for its
reasonable out-of-pocket expenses incurred in complying with its obligations
under this Section 10(f) insofar as they relate to any Lender; provided, that,
to the extent that such expenses relate to (i) any reregistration of the
Aircraft under Section 8 or any sublease of the Aircraft, (ii) any Event of
Default or (iii) any substitution of Parts or Engines pursuant to the terms
hereof, the Lessor shall not be obligated to reimburse the Lessee for such
increase in expense.

                  (g) Information and Records. The Lessee shall:

                  (i) promptly furnish to the Lessor all such information as the
         Lessor may from time to time reasonably request regarding the Aircraft,
         any Engine or any part thereof, its use, location and condition;

                 (ii) keep, or procure that there are kept, the Technical
         Records and shall keep as part thereof accurate, complete and current
         records of all flights made by the Aircraft, of all Flight Hours and
         Cycles of the Airframe, each Engine, the APU, the landing gear and the
         Parts, and of all maintenance and repairs carried out on the Aircraft
         and each Engine and every Part;

                (iii) procure that the Technical Records shall be kept and
         maintained in English and in such manner, form and location as the FAA
         and any applicable law may from time to time require and shall disclose
         the location of all Engines and Parts not installed on the Aircraft,
         which Technical Records, unless otherwise required by applicable law,
         shall be the property of the Lessor;

                 (iv) make the Technical Records available to the Lessor (or any
         authorized representative of the Lessor) for examination during normal
         business hours (or at such other time as the Lessee and the Lessor
         shall mutually agree) upon giving reasonable written notice, provided
         that, so long as no Event of Default shall have occurred and be
         continuing, such examination does not impede the normal commercial
         operation of the Aircraft, and provided further that the cost of any
         such inspection shall be borne by the Lessee if the Lessee is thereby
         shown to be in breach of its material obligations hereunder, and
         otherwise by the party making the inspection; and

                  (v) promptly on, but in no event later than three Business
         Days after, becoming aware of the same, notify the Lessor of: (I) any
         Total Loss with respect to the

                                      -60-
<PAGE>

         Aircraft or any Engine, (II) any loss, theft, damage or destruction to
         the Aircraft or any Engine or any part thereof if the potential cost of
         repairs or replacement may exceed $5,000,000, (III) any loss, arrest,
         hijacking, confiscation, seizure, requisitioning, impounding, taking in
         execution, detention or forfeiture of the Aircraft or any part thereof
         and (IV) any event in respect of the Aircraft that might reasonably be
         expected to involve the Lessor, the Lessee, the Agent or any Lender in
         any loss or liability.

                  SECTION 11. Replacement and Pooling of Parts; Alterations,
Modifications and Additions. (a) Except as otherwise provided in Section 11(d),
the Lessee, at its own cost and expense, will promptly replace all Parts, which
may from time to time be incorporated or installed in or attached to the
Airframe or any Engine and which may from time to time become worn out, lost,
stolen, destroyed, seized, confiscated, damaged beyond repair or permanently
rendered unfit for use for any reason whatsoever. In addition, in the ordinary
course of maintenance, service, repair or testing, the Lessee at its own cost
and expense may remove any Parts, whether or not worn out, lost, stolen,
destroyed, seized, confiscated, damaged beyond repair or permanently rendered
unfit for use; provided, that, except as otherwise provided in Section 11(d),
the Lessee at its own cost and expense shall replace such Parts as promptly as
practicable. All replacement Parts shall be owned by the Lessor free and clear
of all Liens (except Permitted Encumbrances and for pooling arrangements to the
extent permitted by Section 11(b)), and shall be in as good operating condition
as, and shall have a value and utility at least equal to, the Parts replaced,
assuming that such parts were in the condition and repair required to be
maintained by the terms hereof.

                  All Parts at any time removed from the Airframe or any Engine
shall remain the property of the Lessor and shall remain subject to the lien and
security interest of the Aircraft Chattel Mortgage, no matter where located,
until such time as such Parts shall be replaced by parts that have been
incorporated or installed in or attached to the Airframe or any Engine and that
meet the requirements for replacement parts specified above. Immediately upon
any replacement Part becoming incorporated or installed in or attached to the
Airframe or any Engine as above provided, without further act, (A) title to such
replacement Part shall vest in and such replacement part shall become the
property of the Lessor and shall become subject to this Lease and the lien and
security interest of the Aircraft Chattel Mortgage and shall be deemed part of
the Airframe or such Engine for all purposes hereof to the same extent as the
property originally comprising, or installed on, such Airframe or such Engine,
and (B) title to the replaced part shall no longer be the property of the Lessor
and shall thereupon become free and clear of all rights of the Lessor hereunder
and all rights derivative of the Lessor's and shall no longer be deemed a Part
hereunder.

                  (b) Any Part removed from the Airframe or any Engine as
provided in Section 11(a) may be subjected by the Lessee to a normal pooling
arrangement of the type customary in the airline industry entered into by the
Lessee in the ordinary course of its business and entered into with Domestic Air
Carriers that are not the subject of any bankruptcy,




                                      -61-
<PAGE>

insolvency, or similar proceeding, voluntary or involuntary; provided, that the
Part replacing such removed Part shall be incorporated or installed in or
attached to the Airframe or such Engine in accordance with Section 11(a) as
promptly as possible after the removal of such removed part. In addition, any
replacement Part when incorporated or installed in or attached to the Airframe
or any Engine in accordance with Section 11(a) may be owned by any third party
subject to such a pooling arrangement, provided that the Lessee, at its expense,
as promptly thereafter as possible, either (A) causes such replacement Part to
become property of the Lessor and subject to the lien and security interest of
the Aircraft Chattel Mortgage in accordance with Section 11(a) free and clear of
all Liens (except Permitted Encumbrances and the Aircraft Chattel Mortgage
relating to the Aircraft) or (B) replaces such replacement Part by incorporating
or installing in or attaching to the Airframe or such Engine a further
replacement Part owned by the Lessee which shall become the property of the
Lessor subject to the lien and security interest of the mortgage free and clear
of all Liens (except Permitted Encumbrances and the Aircraft Chattel Mortgage
relating to the Aircraft).

                  (c) The Lessee, at its own cost and expense, shall make or
cause to be made such alterations and modifications in and additions to the
Airframe and the Engines as may be required from time to time to meet the
standards of the FAA or other governmental authority having jurisdiction;
provided, that the Lessee may, in good faith, contest the validity or
application of any such standard in any reasonable manner that shall not
adversely affect the Lessor's or the Agent's respective interests. The Lessee
also agrees, at its own cost and expense, to make or cause to be made such
alterations and modifications in and additions to the Airframe and the Engines
as may be required from time to time to meet the standards or requirements of
any directive issued by a manufacturer relating to the Airframe or any Engine.
In addition, so long as no Default or Lease Event of Default shall have occurred
and be continuing, the Lessee, at its own cost and expense, may from time to
time make such alterations and modifications in and additions to the Airframe
and any Engine as the Lessee may deem desirable in the proper conduct of its
business, provided that no such alteration, modification or addition diminishes
the value or utility or impairs the condition or airworthiness of the Airframe
or such Engine below the value, utility, condition or airworthiness thereof
immediately prior to such alteration, modification or addition, assuming that
the Airframe or such Engine were then in the condition and airworthiness
required to be maintained by the terms of this Lease.

                  (d) All Parts incorporated or installed in or attached to or
added to the Airframe or any Engine as the result of such alteration,
modification or addition shall, without further act, become the property of, and
title to such parts shall vest in the Lessor and shall be subject to the lien
and security interest of the Aircraft Chattel Mortgage; provided, that, so long
as no Default or Lease Event of Default shall have occurred and be continuing,
the Lessee may remove and not replace any such Part if it (A) is in addition to,
and not in replacement of or in substitution for, any Part incorporated or
installed in or attached to the Airframe or such Engine on the date hereof, or
any Part in replacement of or substitution for any such

                                      -62-

Part, (B) is not required to be incorporated or installed in or attached or
added to the Airframe or such Engine pursuant to the terms of Section 10(a)
hereof or any other provision of this Lease or the Aircraft Chattel Mortgage and
(C) can be removed from the Airframe or such Engine without diminishing or
impairing the value, utility or airworthiness that the Airframe or such Engine
would have had at such time had such alteration, modification or addition not
occurred, assuming that the Airframe or such Engine was otherwise in the
condition required by this Lease and the Aircraft Chattel Mortgage. Upon the
removal by the Lessee of any such Part, as above provided, title thereto shall,
without further act, be free and clear of the interests of the Lessor and all
rights derivative of the Lessor's and such Part shall no longer be deemed a Part
hereunder.

                  (e) In no event shall the Lessor bear any liability or cost
whatsoever for (i) any alteration or modification of, or addition to, the
Airframe or any Engine, (ii) any grounding of the Aircraft, (iii) suspension of
certification of the Aircraft, or (iv) loss of revenue suffered by the Lessee
for any reason whatsoever.

                  SECTION 12. Indemnities. (a) The Lessee will pay, and hereby
indemnifies, on an after-tax basis, the Lessor and its assignees, if any, from
and against, any and all fees and taxes, levies, imposts, duties, charges or
withholdings, together with any penalties, fines or interest thereon (any of the
foregoing for the purposes of this Section 12 being called a "TAX"), that may
from time to time be imposed on or asserted against the Lessor and its
assignees, if any, or the Airframe or any Engine or any part thereof or interest
therein by any federal, state or local government or other taxing authority in
the United States or by any foreign government or subdivision thereof or by any
foreign taxing authority in connection with, relating to or resulting from: (i)
the Airframe or any Engine or any part thereof or interest therein, (ii) the
manufacture, purchase, ownership, mortgaging, lease, sublease, use, storage,
maintenance, sale or other disposition of the Airframe or any Engine, (iii) any
rentals or other earnings therefor or arising therefrom or the income or other
proceeds received with respect thereto, or (iv) this Lease or the Aircraft
Chattel Mortgage; provided, however, that there shall be excluded from any
indemnification under this Section 12(a) any Lessor Tax unless the payment of
any such Tax shall be a condition to the enforceability of the Aircraft Chattel
Mortgage or the perfection of the lien thereof or unless proceedings shall have
been commenced to foreclose any lien that may have attached as security for such
Tax, nothing in this Section shall require the payment of any Tax so long as and
to the extent that the validity thereof shall be contested in good faith by
appropriate legal proceedings promptly instituted and diligently conducted and
the Lessee shall have set aside on its books adequate reserves with respect
thereto in accordance with generally accepted accounting principles.

                  (b) The Lessee agrees to defend, indemnify, pay and hold
harmless the Lessor, the Agent and each Lender, and the officers, directors,
partners, employees, agents and affiliates of the Lessor, the Agent and each
Lender, (collectively called the "INDEMNITEES") from and against any and all
liabilities, obligations, losses, damages, penal-

                                      -63-
<PAGE>

ties, actions, judgments, suits, claims, costs, expenses and disbursements of
any kind or nature whatsoever (including, without limitation, the reasonable
fees and disbursements of counsel for such Indemnitees in connection with any
investigative, administrative or judicial proceeding, commenced or threatened by
any Person, whether or not any such Indemnitee shall be designated as a party or
a potential party thereto), whether direct, indirect or consequential and
whether based on any federal, state or foreign laws, statutes, rules or
regulations (including, without limitation, securities and commercial laws,
statutes, rules or regulations and Environmental Laws), on common law or
equitable or other cause or on contract or otherwise, that may be imposed on,
incurred by, or asserted against any such Indemnitee, in any manner relating to
or arising out of this Lease or the other Transaction Documents or the
transactions contemplated hereby or thereby (including, without limitation, the
Lenders' agreement to make the Loans to the Lessor or the use or intended use of
the proceeds of any of the Loans) (collectively called the "INDEMNIFIED
LIABILITIES"); provided, that the Lessee shall not have any obligation to any
Indemnitee hereunder with respect to any Indemnified Liabilities to the extent
that such Indemnified Liabilities arise solely from the gross negligence or
willful misconduct of that Indemnitee as determined by a final judgment of a
court of competent jurisdiction. To the extent that the undertaking to defend,
indemnify, pay and hold harmless set forth in the preceding sentence may be
unenforceable because it is violative of any law or public policy, the Lessee
shall contribute the maximum portion that it is permitted to pay and satisfy
under applicable law to the payment and satisfaction of all Indemnified
Liabilities incurred by the Indemnitees or any of them.

                  SECTION 13. Event of Loss. (a) If an Event of Loss shall occur
with respect to an Airframe or an Engine, the Lessee will promptly notify the
Lessor and the Agent thereof in writing (in any event within five (5) days of
such occurrence) and will, not later than 180 days after the occurrence of such
Event of Loss, convey or cause to be conveyed to the Lessor, free of all Liens
(other than Permitted Encumbrances) title to an Acceptable Alternate Airframe or
Acceptable Alternate Engine, as the case may be. Prior to or at the time of any
such conveyance, the Lessee, at its own expense, will, as conditions to such
transfer, (i) furnish the Lessor with a warranty (as to title) bill of sale,
from a person and in form and substance reasonably satisfactory to the Lessor,
with respect to such Acceptable Alternate Airframe or Acceptable Alternate
Engine, (ii) cause a Lease Supplement to be filed for recording pursuant to
Title 49 of the United States Code, as amended, (iii) furnish the Lessor with
such evidence of the Lessee's title to such Acceptable Alternate Airframe or
Acceptable Alternate Engine and of compliance with the insurance provisions of
Section 14 hereof with respect to such Acceptable Alternate Airframe or
Acceptable Alternate Engine as the Lessor may reasonably request, (iv) furnish
the Lessor with an opinion of the Lessee's counsel to the effect that title to
such Acceptable Alternate Airframe or Acceptable Alternate Engine has been duly
conveyed to the Lessor free and clear of all Liens except Permitted Encumbrances
and the Lessor and the Agent continue to have 1110 protection with respect to
such Aircraft. Upon satisfaction of the foregoing conditions, the Lessor shall
transfer to or at the direction of the Lessee without recourse or warranty all
of the Lessor's right, title and interest, if any, in and to

                                      -64-
<PAGE>

(A) the Airframe or Engine with respect to which such Event of Loss occurred and
furnish to or at the direction of the Lessee, at the Lessee's expense, a bill of
sale without warranty other than to the absence of a Lessor Lien in form and
substance reasonably satisfactory to the Lessee, evidencing such transfer and
(B) all claims, if any, against third parties, for damage to or loss of the
Airframe or Engine subject to such Event of Loss, and such Airframe or Engine
shall thereupon cease to be an Airframe or Engine leased hereunder. The Lessee
shall cooperate with the Lessor and take all such actions as shall be requested
by the Lessor so that the Lessor complies with Section 4(f) of the Aircraft
Chattel Mortgage. For all purposes hereof, each such Acceptable Alternate
Airframe or Acceptable Alternate Engine shall, after such conveyance, be deemed
part of the property leased hereunder, and shall be deemed an "Airframe" or
"Engine," as the case may be. No Event of Loss under the circumstance
contemplated by the terms of this paragraph (a) shall result in any reduction in
Basic Rent or any other obligation of the Lessee hereunder.

                  (b) With respect to the Airframe or any Engine, as between the
Lessor and the Lessee, any payments on account of an Event of Loss (other than
insurance proceeds or other payments the application of which is provided for in
Section 14 below) received from any governmental authority or other person shall
be applied as follows:

                  (A) if such payments are received with respect to an Event of
         Loss to an Airframe or Engine that has been or is being replaced by the
         Lessee pursuant to the terms hereof, so long as there shall exist no
         Default or Lease Event of Default, such payment shall be paid over to
         or retained by the Lessee upon satisfaction of the conditions for
         replacement contained in paragraph (a) above and until such time shall
         be held by the Lessor as security for the obligations of the Lessee
         under the Lease; and

                  (B) if such payments are received with respect to an Event of
         Loss with respect to which no replacement is being effected, so much of
         such payments as shall not exceed (A) the Stipulated Loss Value as of
         the date of payment plus (B) all unpaid Supplemental Rent due through
         the date of payment, plus (C) all unpaid Basic Rent for the period
         ending on the date of payment shall be paid by the Lessee to the Lessor
         and following the foregoing application, the balance, if any, of such
         payments shall be distributed between the Lessee and the Lessor as
         their respective interests may appear;

                  (c) In the event of a requisition for use by the United States
Government of the Airframe or any Engine, the Lessee shall promptly notify the
Lessor and the Agent of such requisition and all of the Lessee's obligations
under the Lease shall continue to the same extent as if such requisition had not
occurred. Any payments received by the Lessor or the Lessee from the United
States Government for the use of the Airframe or such Engine, to the extent
allocable to the Term, shall be paid over to, or retained by, the Lessee.

                  (d) Any amount referred to in this Section 13 that is payable
to or retained by the Lessee shall not be paid to the Lessee or retained by the
Lessee, if at the time of such




                                      -65-
<PAGE>

payment or retention any Default or Lease Event of Default shall have occurred
and be continuing, but shall be held by or paid over to the Lessor as security
for the obligations of the Lessee under the Lease and shall be applied against
the Lessee's obligations hereunder as and when due. At such time as there shall
not be continuing any such Default or Lease Event of Default, such amount shall
be paid to the Lessee to the extent not previously applied in accordance with
the preceding sentence.

                  SECTION 14. Insurance. (a) The Lessee will at all times carry
and maintain on or with respect to the Aircraft, at its own cost and expense,
public liability (including, without limitation, contractual liability, cargo
liability, passenger legal liability, bodily injury and product liability, but
excluding manufacturer's product liability) and property damage insurance with
insurers of recognized responsibility and reputation in amounts, of the type and
covering the risks customarily carried with respect to similar aircraft by
corporations engaged in the same or similar business and similarly situated with
the Lessee but in no event in an amount less than $500,000,000 per occurrence
(which shall include war risk, governmental confiscation and expropriation and
allied perils coverage). During any period when the Aircraft is on the ground
and not in operation, the Lessee may carry or cause to be carried, in lieu of
insurance required by this Section, insurance otherwise conforming with the
provisions of this Section except that the amounts of coverage shall not be
required to exceed the amounts of comprehensive airline liability insurance, and
the scope of risk covered and type of insurance shall be the same, as are
customarily carried with respect to similar aircraft on the ground by
corporations engaged in the same or similar business and similarly situated with
the Lessee. Any policies of insurance carried in accordance with this Section 14
and any policies taken out in substitution or replacement of any such policies
(A) shall be amended to name the Agent, the Lenders and the Lessor and their
respective shareholders, directors, officers, members, partners, servants,
employees and agents as additional named insureds, (B) shall be primary without
right of contribution from any other insurance that is carried by the Lessee,
(C) shall expressly provide that all provisions thereof, except the limits of
the liability, shall operate in the same manner as if there were a separate
policy covering each insured, and (D) shall provide that the insurer shall waive
any right of subrogation against the Agent, the Lenders and the Lessor.

                  (b) The Lessee will at all times carry and maintain with
insurers of recognized responsibility and reputation on or with respect to the
Aircraft, at its own cost and expense, aircraft ground and flight all-risk hull
insurance as well as fire and extended coverage insurance on the Engines and
other equipment while removed from the Airframe, which shall include war risk,
governmental confiscation and expropriation (other than by the United States
Government) and allied perils (if and to the extent that the same shall be
maintained by the Lessee with respect to similar aircraft owned or operated by
the Lessee on the same routes or if the Aircraft or another aircraft is operated
on routes where the custom is for Domestic Air Carriers similarly situated with
the Lessee flying comparable routes with similar aircraft to carry such
insurance, of the type usually carried by corporations engaged in the same or
simi-



                                      -66-
<PAGE>

lar business and similarly situated with the Lessee) including (A) strikes,
riots, civil commotions or labor disturbances, (B) any malicious act or act of
sabotage and (C) hijacking (air piracy) or any unlawful seizure or wrongful
exercise of control of the Aircraft or crew in flight (including any attempt at
such seizure or control) made by any person or persons aboard the Aircraft or
another aircraft acting without the consent of the insured; provided, that such
insurance (including any self-insurance to the extent permitted below) shall at
all times be for an agreed value not less than the greater of the Stipulated
Loss Value as of the closest Stipulated Loss Determinate Date and $50,000,000.
During any period when the Aircraft is on the ground and not in operation, the
Lessee may carry or cause to be carried, in lieu of the insurance required by
this Section, insurance otherwise conforming hereto except that the scope of
risk covered and type of insurance shall be the same as are from time to time
customarily carried with respect to similar aircraft by corporations engaged in
the same or similar business and similarly situated with the Lessee for aircraft
on the ground in an amount at least equal to the applicable amount provided
above. All such insurance shall name the Agent, the Lenders and the Lessor as
additional insureds and loss payees to the extent that their interest may appear
and shall provide that any loss to the Airframe or an Engine in excess of
$2,000,000 (and, if a Default or Lease Event of Default has occurred and is
continuing, any such loss) shall be payable to the Lessor and to the Agent for
the benefit of the Lenders; and shall be primary without right of contribution
from any other insurance that is carried by the Lessor or the Agent with respect
to its interest therein. In the event that the Lessee arranges separate
insurances to cover the all-risk hull insurance and the war and perils hull
insurance, the Lessee shall ensure that the insurers subscribing to such
insurances shall agree to a 50/50 claims funding arrangement in the event of any
dispute as to which insurance is applicable.

                  The Lessee may self-insure, by way of deductible or equivalent
provisions in insurance policies, the risks required to be insured against
pursuant to this Section 14(b) in such reasonable amounts as are then applicable
to other similar aircraft or spare engines in the Lessee's fleet that are of a
value comparable to the Aircraft, and as are not substantially greater than
amounts self-insured by corporations engaged in the same or similar business and
similarly situated with the Lessee; provided, however, that the Lessee may not
self-insure in an amount in excess of $1,000,000 without the prior written
consent of the Lessor and the Agent.

                  (c) Any policies of insurance required pursuant to either
paragraph (a) or paragraph (b) above shall: (A) be amended to name the Lessor,
the Agent and the Lenders as additional named insureds, but without the Lessor,
the Agent or the Lenders being thereby liable for premiums (and the insurance
companies waiving their right with respect thereto), (B) provide that in respect
of the interest of (x) the Lessor or (y) the Agent or the Lenders in such
policies the insurance shall not be invalidated by any action or inaction of (x)
the Lessee or (y) the Lessee or the Lessor, respectively, and shall insure the
interests of the Agent and the Lenders regardless of any breach or violation by
the Lessee, the Lessor or any Person (other than the Agent) of any warranty,
declaration, condition or exclusion from coverage contained



                                      -67-
<PAGE>


in such policies, (C) provide that if such insurance is cancelled, or if any
material change is made in the coverage that affects the interest of the Lessor,
the Agent or any Lender, or if such insurance is allowed to lapse for nonpayment
of premium, such cancellation, change or lapse shall not be effective as to the
Lessor, the Agent or any Lender for thirty (30) days (seven (7) days, or such
shorter or longer period as may from time to time be customarily available in
the industry, in the case of any war risk and allied perils coverage) after
receipt by the Agent and the Lessor of written notice from such insurers of such
cancellation, change or lapse, (D) be in full force and effect throughout any
geographical areas at any time traversed by the Aircraft and shall be payable in
U.S. dollars, (E) waive any right of the insurers to any setoff or counterclaim
or any other deduction, whether by attachment or otherwise in respect of any
liability of the Lessee, the Lessor or the Agent except in respect of
outstanding premium due for the Aircraft, (F) waive all rights of subrogation
against the Lessor and the Agent and (G) include a year 2000 date recognition
writeback.

                  (d) In the case of a lease or contract with the United States
or any agency or instrumentality thereof in respect of the Airframe or any
Engine, a valid agreement by the United States or such agency or instrumentality
to indemnify the Lessee against the same risks against which the Lessee is
required hereunder to insure shall be considered adequate insurance with respect
to the Airframe or such Engine to the extent of the risks and in the amounts
that are the subject of any such agreement to indemnify.

                  (e) On or prior to the date hereof, and annually thereafter on
or prior to January 31, the Lessee will furnish to the Lessor and the Agent (A)
a report signed by a firm of independent aircraft insurance brokers, appointed
by the Lessee and not objected to by the Lessor or the Agent, describing in
reasonable detail acceptable to the Lessor and the Agent the insurance then
carried and maintained on or with respect to the Aircraft and the Engines and
stating that in the opinion of such firm such insurance complies with the terms
of this Section 14 and is adequate to protect the interests of the Lessee, the
Lessor and the Agent, and (B) certificates of the insurer or insurers evidencing
the insurance covered by the report. The Lessee will cause such brokers to
advise the Agent in writing (x) promptly of any default in the payment of any
premium and of any other act or omission on the part of the Lessee of which such
firm has knowledge and that might invalidate or render unenforceable, in whole
or in part, any insurance on the Aircraft or any Engine and (y) at least thirty
(30) days prior to the expiration or termination date, or date of effectiveness
of any material change, of any insurance carried and maintained on the Aircraft
hereunder.

                  (f) All insurance payments and other payments received by the
Agent, the Lessor or the Lessee from insurance referred to in paragraph (b)
above shall be, if received by the Lessor or the Lessee, immediately paid to the
Agent, as agent for itself and the Lessor and shall be paid to the Lessee upon
compliance by the Lessee with the terms of Section 13, provided that no Default
or Lease Event of Default shall have occurred and be continuing.


                                      -68-
<PAGE>

                  (g) The Lessee shall not create or permit to exist any Lien
over the insurances required by this Lease, or its interest therein, save as
constituted by this Lease and the Credit Agreement.

                  (h) If at any time the Lessee fails to maintain in full force
and effect insurances in compliance with any provision of this Article 14, the
Lessor shall be entitled but not bound (without prejudice to any other rights
that it may have or acquire under this Lease by reason of such failure) (i) to
pay any premiums due or to effect or maintain insurances satisfactory to the
Lessor or otherwise remedy such failure in such manner as the Lessor considers
appropriate, and the Lessee shall immediately reimburse the Lessor in full for
any amount so expended by the Lessor and/or (ii) at any time while such failure
is continuing, to require the Aircraft to remain at any airport, or to proceed
to and remain at any airport designated by the Lessor, the Agent or the Lenders,
until such failure is remedied.

                  (i) Nothing in this Section 14 shall prohibit the Agent, or
any Lender or the Lessor from obtaining insurance with respect to the Aircraft
for its own account. The Lessee may, at its own expense, carry insurance with
respect to its interest in the Aircraft in amounts in excess of that required to
be maintained by this Section 14. No insurance maintained by the Agent, the
Lessor or any Lender shall prevent the Lessee from carrying the insurance
required or permitted by this Section. Proceeds of any such insurance carried by
the Lessee, the Agent or any Lender shall be paid as provided in the insurance
policy relating thereto and no such Person shall have any duty to obtain any
such insurance.

                  SECTION 15. Assignment. Except as permitted in accordance with
Section 10, the Lessee will not, without the prior written consent of the
Lessor, assign any of its rights hereunder or in the Aircraft. The Lessor agrees
that it will not assign or convey its right, title or interest in or to this
Lease or the Aircraft except in accordance with the Credit Agreement. Subject to
the foregoing, the terms and provisions of this Lease shall be binding upon and
inure to the benefit of the Lessor and the Lessee and their respective
successors and permitted assigns and shall inure to the direct benefit of, and
shall also be enforceable by, the Agent and the Lenders, and their respective
successors, as assignees of the Lessor.

                  SECTION 16. Events of Default. Each of the following events
shall constitute a Lease Event of Default (whether any such event shall be
voluntary or involuntary or come about or be effected by operation of law or
pursuant to or in compliance with any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body) and
each such Lease Event of Default shall continue so long as, but only as long as,
it shall not have been remedied:

                  (a) the Lessee shall fail to pay any installment of Rent,
         Stipulated Loss Value or any other amounts owing pursuant to this Lease
         within 5 days after the due date thereof;

                                      -69-
<PAGE>

                  (b) the Lessee shall fail (i) to comply in any material
         respect with the maintenance standards or (ii) to procure insurance
         coverage as prescribed herein or (iii) to operate the Aircraft or any
         Engine at a time or in a place where insurance described in Article 14
         shall not be in effect;

                  (c) there shall exist a Lease Event of Default under, and as
         defined in, any other Lease or the Lessee shall fail to perform or
         observe any other covenant or condition set forth in this Lease or any
         other Transaction Document, which failure shall remain unremedied for a
         period of 10 Business Days after written notice from the Lessor or the
         Agent, unless action has been taken within 15 Business Days to remedy
         such breach and such action is being diligently pursued, provided such
         breach is capable of being remedied;

                  (d) any representation or warranty of the Lessee in any
         Transaction Document or in any certificate furnished pursuant to any
         Transaction Document is found to be incorrect in any material respect
         at the time it was made and such breach shall remain unremedied for a
         period of 15 Business Days after written notice thereof;

                  (e) (i) a court having jurisdiction in the premises shall
         enter a decree or order for relief in respect of the Lessee or any of
         its Subsidiaries in an involuntary case under the Bankruptcy Code or
         under any other applicable bankruptcy, insolvency or similar law now or
         hereafter in effect, which decree or order is not stayed; or any other
         similar relief shall be granted under any applicable federal or state
         law, or (ii) an involuntary case shall be commenced against the Lessee
         or any of its Subsidiaries under the Bankruptcy Code or under any other
         applicable bankruptcy, insolvency or similar law now or hereafter in
         effect; or a decree or order of a court having jurisdiction in the
         premises for the appointment of a receiver, liquidator, sequestrator,
         trustee, custodian or other officer having similar powers over the
         Lessee or any of its Subsidiaries, or over all or a substantial part of
         its property, shall have been entered; or there shall have occurred the
         appointment of an interim receiver, trustee or other custodian of the
         Lessee or any of its Subsidiaries; or a warrant of attachment,
         execution or similar process shall have been issued against any
         substantial part of the property of the Lessee or any of its
         subsidiaries, and any such event described in this clause (ii) shall
         continue for 60 days unless dismissed, bonded or discharged;

                  (f) (i) the Lessee or any of its Subsidiaries shall have an
         order for relief entered with respect to it or commence a voluntary
         case under the Bankruptcy Code or under any other applicable
         bankruptcy, insolvency or similar law now or hereafter in effect, or
         shall consent to the entry of an order for relief in an involuntary
         case, or to the conversion of an involuntary case to a voluntary case,
         under any such law, or shall consent to the appointment of or taking
         possession by a receiver, trustee or other custodian for all or a
         substantial part of its property; or the Lessee or any of its
         Subsidiaries shall make any assignment for the benefit of creditors; or

         admit in writing its inability, to pay its debts as such debts become
         due; or the Board of Directors of the Lessee or any of its Subsidiaries
         (or any committee thereof) shall adopt any resolution or otherwise
         authorize any action to approve any of the actions referred to in
         clause (i) above or this clause (ii);

                  (g) any order, judgment or decree shall be entered against the
         Lessee or any of its Subsidiaries decreeing the dissolution or split up
         of the Lessee or any of its Subsidiaries and such order shall remain
         undischarged or unstayed for a period in excess of 30 days;

                  (h) registration of the Aircraft is canceled and is not cured
         within 15 Business Days;

                  (i) the Aircraft is arrested or detained in exercise of any

                  (j) there shall have occurred an Event of Default or Potential
         Event of Default under the Amended Aircraft Credit Facility (whether or

         similar process involving (i) in any individual case an amount in
         excess of $5 million or (ii) in the aggregate at any time an amount in
         excess of $10 million (in either case not adequately covered by
         insurance as to which a solvent and unaffiliated insurance company has
         acknowledged coverage) shall be entered or filed against the Lessee or
         any of its Subsidiaries or any of their respective assets and shall
         remain undischarged, unvacated, unbonded or unstayed for a period of 60

         and control shares of capital stock of the Lessee representing at least
         30% of the combined voting power of all Securities of the Lessee
         entitled to vote in the election of directors, other than Securities
         having such power only by reason of the happening of a contingency, or
         (b) any Person or any two or more Persons acting in concert (in any
         such case, excluding Permitted Holders) shall have acquired beneficial
         ownership (within the meaning of Rule 13d-3 of the Securities and
         Exchange Commission under the Exchange Act), directly or indirectly, of
         Securities of the Lessee (or other Securities convertible into such
         Securities) representing 20% or more of the combined voting power of
         all Securities of the Lessee entitled to vote in the election of
         directors, other than Securities having such power only by reason of
         the happening of a contingency, or (c) the Board of Directors of the
         Lessee shall not consist of a majority of Continuing Directors or (ii)
         a "Change of Control" shall occur under any of the Pass Through Trust
         Documents, any of the Senior Note Documents or any other Material
         Agreement (as in effect on the date of such occurrence); provided,
         however, that, following the consummation of the Holding Company
         Reorganization, references in clause (i) above to the Lessee shall be
         deemed to be references to the Holding Company, and, after the
         consummation of the Holding Company Reorganization, it shall also be a
         Lease Event of Default if, at any time, the Holding Company ceases to
         own directly or indirectly 100% of the outstanding Securities of the
         Lessee; provided further, however, that a "Lease Event of Default"
         under clause (ii) above arising as a result of the Holding Company
         Reorganization shall not constitute a "Lease Event of Default;"
         provided further, however, that, in the event that Permitted Holders
         cease to own 30% of the combined voting power of all Securities of the
         Lessee (or the Holding Company, as the case may be) because of the
         issuance of Securities of the Lessee, or the Holding Company, as the
         case may be, (as opposed to the Permitted Holders selling Securities),
         then the failure to maintain the 30% ownership level shall not
         constitute a Lease Event of Default unless the Permitted Holders shall
         cease to own shares of capital stock constituting 25% of the combined
         voting power of all Securities of the Lessee (or the Holding Company,
         as the case may be);

         withdrawn or terminated or expires and is not renewed, or otherwise
         ceases to be in full force and effect and the Lessor reasonably
         determines that such modification, withholding revocation, suspension,
         cancellation, withdrawal, termination or non-renewal or cessation may
         significantly prejudice its rights under or in connection with this
         Lease, may have a material adverse effect on the Lessee's ability to
         perform its obligations hereunder or jeopardize the respective
         interests of the Lessor or any Lender in the Aircraft or may give rise
         to criminaliability of or the Lessor;

                  (p) if any event occurs, circumstance arises or proceeding is
         taken with respect to the Lessee in any jurisdiction to which the
         Lessee is subject that has an effect equivalent or similar to any of
         the events mentioned in Sections 16(e) or (f);

                  (q) if the Lessee suspends or ceases or threatens to suspend
         or cease to carry on its business;

                  (r) if the Lessee disposes, threatens to dispose or takes any
         action to dispose of all or a material part of its assets, whether by
         one or a series of transactions, related or not, and such disposal or
         action will have a material adverse effect on its ability to perform
         its obligations under this Lease or any other Transaction Document;

                  (s) if the existence, validity, enforceability or priority of
         the rights of the Lessor in respect of the Aircraft hereunder, or the
         rights of any Lender, as mortgagee, of the Aircraft or the Lender as
         assignee of the insurances are challenged by the Lessee or any other
         person claiming through the Lessee;

                  (t) if the Lessee sells or executes any bill of sale affecting
         the Aircraft or any interest therein or agrees or purposes to do any of
         the same, or contests in any legal proceedings the Lessor's ownership
         of the Aircraft;

                  (u) if any governmental authority shall have condemned, seized
         or appropriated all or substantially all of the property of the Lessee;
         or

                  (v) if the Lessee becomes obligated to make any "change of
         control" put payments in connection with the Holding Company
         Reorganization that, when aggregated with all payments made under
         Section 7(e)(6), exceed $75,000,000 or if, after giving effect to such
         "change of control" put payments, (A) the Lessee shall have less than
         $150,000,000 in Cash or Cash Equivalents on its balance sheet or (B)
         its Consolidated Leverage Ratio (calculated on a pro forma basis as if
         the proposed payment had been consummated on the last day of the most
         recent four fiscal quarter period)

         accordance with Section 7(f)(ii) for the immediately succeeding fiscal
         quarter end.

                  SECTION 17. Remedies. Upon the occurrence of any Lease Event
of Default and at any time thereafter so long as the same shall be continuing,
the Lessor may, at its option, declare, by written notice to the Lessee, this
Lease to be in default, except that upon the occurrence of a Lease Event of
Default referred to in clauses (e), (f) or (g) of Section 16, this Lease shall
be deemed declared in default without any further act or notice, and at any time
thereafter, the Lessor may do one or more of the following with respect to all
or any part of the Aircraft, Airframe and any or all of the Engines as the
Lessor in its sole discretion shall elect:

                  (a) upon the written demand of the Lessor and at the Lessee's
         expense, promptly return the Aircraft, Airframe or any Engine as the
         Lessor may so demand to the Lessor or its order in the manner and
         condition required by, and otherwise in accordance with all the
         provisions of, Section 8 hereof as if such Airframe or Engine were
         being returned at the end of the Term, or the Lessor, at its option,
         may enter upon the premises where all or any part of the Aircraft,
         Airframe or any Engine is located and take immediate possession of and
         remove the same by summary proceedings or otherwise, all without
         liability accruing to the Lessor for or by reason of such entry or
         taking of possession or removal, whether for the restoration of damage
         to property caused by such action or otherwise; provided, that if the
         Lessee shall for any reason fail to execute and deliver instruments
         deemed necessary or advisable by the Lessor to obtain possession of the
         Aircraft, Airframe and Engines, the Lessor shall be entitled, in a
         proceeding (which proceeding may be done on an ex parte basis without
         notice to the Lessee), to a preliminary injunction granting the Lessor
         the right to possess the Aircraft without having to post a bond or
         provide any other type of security and to a final judgment for specific
         performance, conferring the right to immediate possession upon the
         Lessor and requiring the Lessee to execute and deliver such instruments
         to the Lessor;

                  (b) sell the Aircraft, Airframe or any Engine at public or
         private sale, as the Lessor may determine, or otherwise dispose of,
         hold, use, operate, lease to others or keep idle the Aircraft, Airframe
         or any Engine as the Lessor, in its sole discretion, may determine, all
         free and clear of any rights of the Lessee, except as hereinafter set
         forth in this Section 17, and without any duty to account to the Lessee
         with respect to such action or inaction;

                  (c) whether or not the Lessor shall have exercised, or shall
         thereafter at any time exercise, any of its rights under paragraph (a)
         or (b) above with respect to the Aircraft, the Lessor, by written
         notice to the Lessee specifying a payment date, may demand that the
         Lessee pay to the Lessor, and the Lessee shall pay the Lessor, on the
         payment date so specified, any Basic Rent due on or before the payment
         date so speci-

                                      -74-
<PAGE>

         fied plus, as liquidated damages for loss of a bargain and not as a
         penalty (in lieu of the installments of Basic Rent for the Aircraft due
         after the date specified in such notice if any), an amount equal to the
         Stipulated Loss Value for the Aircraft computed as of the immediately
         preceding Stipulated Loss Determination Date, together with interest,
         if any, at the Past Due Rate on the amount of such Basic Rent and
         Stipulated Loss Value from the Stipulated Loss Determination Date as of
         which Stipulated Loss Value is computed until the date of actual
         payment; and upon such payment of liquidated damages and all
         Supplemental Rent then due and payable by the Lessee hereunder, the
         Lessor shall transfer (without any representation, recourse or warranty
         whatsoever) the Aircraft to the Lessee and the Lessor shall execute and
         deliver such documents evidencing such transfer and take such further
         action as the Lessee shall reasonably request to effect such transfer;

                  (d) in the event that the Lessor, pursuant to paragraph (b)
         above, shall have sold the Aircraft, the Lessor, in lieu of exercising
         its rights under paragraph (c) above with respect to such Aircraft,
         may, if it shall so elect, demand that the Lessee pay the Lessor, and
         the Lessee shall pay to the Lessor, on the date of such sale, any
         accrued rent with respect to the Aircraft due on or prior to such date
         plus, as liquidated damages for loss of a bargain and not as a penalty,
         the amount of any deficiency between the net proceeds of such sale
         (after deduction of all reasonable costs of sale) and the Stipulated
         Loss Value of such Aircraft, computed as of the date of such sale
         together with interest, if any, on the amount of such deficiency, at
         the Past Due Rate, from the date of such sale to the date of actual
         payment of such amount;

                  (e) the Lessor may terminate or cancel this Lease or proceed
         by appropriate court action to enforce the terms hereof or to recover
         damages for breach hereof; and

                  (f) the Lessor may exercise any other right or remedy which
         may be available to it under applicable law.

                  In addition, the Lessee shall be liable, except as otherwise
provided above, without duplication of amounts payable hereunder, for any and
all unpaid Rent due hereunder before, after or during the exercise of any of the
foregoing remedies and for all reasonable legal fees and other costs and
expenses incurred by the Lessor and the Agent and any Lender (including
reasonable allocated time charges of internal counsel for the Lender) in
connection with the Lease Event of Default, the exercise of remedies and the
return of the Airframe or any Engine in accordance with the terms of Section 8
hereof or in placing such Airframe or Engine (which for purposes hereof, shall
include, without limitation, all logs, manuals and data and inspection,
maintenance, modification and overhaul and similar records with respect thereto)
in the condition and airworthiness required by such Section. The Lessee hereby
acknowledges that it shall be directly liable for such costs and expenses to any
Person designated by the Lessor, the Agent or any Lender (as the case may be) to
provide services in connection with or to effect the return of the Airframe or
any Engine in accordance with the terms



                                      -75-
<PAGE>

of Section 8 hereof or in placing such Airframe or Engine (which for purposes
hereof shall include, without limitation, such logs, manuals and records) in the
condition and airworthiness required by such Section.

                  At any sale of the Aircraft or any part thereof pursuant to
this Section 17, the Lessor or the Agent or any Lender may bid for and purchase
such property. The Lessor agrees to give the Lessee at least 10 days' written
notice of the date fixed for any public sale of any Airframe or Engine or of the
date on or after which will occur the execution of any contract providing for
any private sale. Except as otherwise expressly provided above, no remedy
referred to in this Section 17 is intended to be exclusive, but each shall be
cumulative and in addition to any other remedy referred to above or otherwise
available to the Lessor at law or in equity or otherwise; and the exercise or
beginning of exercise by the Lessor of any one or more of such remedies shall
not preclude the simultaneous or later exercise by the Lessor of any or all of
such other remedies. No waiver by the Lessor of any Lease Event of Default shall
in any way be, or be construed to be, a waiver of any future or subsequent Lease
Event of Default. To the extent permitted by applicable law, the Lessee hereby
waives any rights now or hereafter conferred by statute or otherwise that may
require the Lessor to sell, lease, or otherwise use the Aircraft, Airframe or
any Engine or any part thereof in mitigation of the Lessor's damages as set
forth in this Section 17 or that may otherwise limit or modify any of the
Lessor's rights and remedies in this Section 17.

                  Notwithstanding any of the foregoing provisions of this
Section 17, so long as any Loan relating to the Aircraft or other Obligations
(other than principal and interest on Loans relating to other aircraft or spare
engines) are outstanding under the Credit Agreement, all rights of the Lessor
under this Section 17 shall be exercised only by the Agent as assignee of the
Lessor's rights under this Lease pursuant to the Aircraft Chattel Mortgage.

                  SECTION 18. Lessee's Cooperation Concerning Certain Matters.
(a) Forthwith upon the execution and delivery of each Lease Supplement from time
to time required by the terms hereof and upon the execution and delivery of any
amendment to this Lease, the Lessee (at its expense), unless such supplement or
amendment relates solely to the assignment of all or any portion of the Lessor's
interest hereunder, will cause such Lease Supplement (and, in the case of the
initial Lease Supplement, this Lease as well) or amendment to be duly filed and
recorded, and maintained of record, in accordance with the applicable laws of
the government of registry of the Aircraft. In addition, the Lessee at its
expense will promptly and duly execute and deliver to the Lessor and the Agent
such further documents and take such further action as the Lessor and the Agent
may from time to time reasonably request in order more effectively to carry out
the intent and purpose of this Lease and the other Transaction Documents and to
establish and protect the rights and remedies created or intended to be created
in favor of the Lessor and the Agent hereunder and under the other Transaction
Documents, including, without limitation, if requested by the Lessor and the
Agent, the execution and delivery of supplements or amendments hereto, at the
expense of the



                                      -76-
<PAGE>

Lessee, each in recordable form, and all financing statements and
continuation statements, and all similar notices required by applicable law at
all times to be kept recorded and filed in such manner and such places as the
Lessor and the Agent may reasonably request.

                  (b) The Lessee agrees at its own expense to furnish to the
Lessor and the Agent promptly after execution and delivery of any supplement and
amendment hereto, an opinion of counsel satisfactory to the Lessor and the Agent
(which may include the Lessee's general counsel) stating that, in the opinion of
such counsel, such supplement or amendment to the Lease (or a financing
statement, continuation statement or similar notice thereof if and to the extent
permitted or required by applicable law) has been properly recorded or filed for
record in all public offices in which such recording or filing is necessary to
protect the right, title and interest of the Lessor hereunder and the Agent
under the Loan Documents.

                  SECTION 19. Notices. All notices required under the terms and
provisions hereof shall be in writing (including telex, facsimile or similar
writing) and shall be effective (a) if given by facsimile device, when
transmitted and the appropriate confirmation received, (b) if given by certified
mail, three Business Days after being deposited in the United States mail, with
appropriate postage prepaid, (c) if given by telex, upon receipt by the party
transmitting the telex of such party's answerback code at the end of such telex
(receipt of confirmation in writing not being necessary to the effectiveness of
any telex) and (d) if given by overnight service or other means, when received
or personally delivered, addressed:

                  (i) if to the Lessee, at 538 Commons Drive, Golden, Colorado

         from time to time designate in writing to the Lessor; and

                 (ii) if to the Lessor, at 538 Commons Drive, Golden, Colorado
         80401, Attention: Mr. Richard H. Shuyler, or to such other address as
         the Lessor shall from time to time designate in writing to the Lessee,
         with a copy to the Agent at 130 Liberty Street, New York, New York
         10006, Attention: Marguerite Sutton.

                  SECTION 20. Net Lease, True Lease, etc. (a) The Lessee's
obligations to pay Rent and all other amounts payable hereunder shall be
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including, without limitation, (i) any setoff, counterclaim,
recoupment, defense or other right that the Lessee may have against the Lessor,
the Agent, the Lenders, any manufacturer, any supplier or any other Person for
any reason whatsoever, (ii) any defect in the title, airworthiness, eligibility
for registration under Title 49 of the United States Code, as amended, or other
applicable law, condition, design, compliance with specifications, operation or
fitness for use of, or any damage to or loss or destruction of, the Aircraft, or
any theft, interference, interruption or cessation in or prohibition of the use
or possession thereof by the Lessee or any sublessee for any reason whatsoever,
including, without limitation, any such interference, interruption, cessation or
prohibition resulting from the act of any governmental authority or any other
Person, (iii) any Liens, en-



                                      -77-

cumbrances or rights of any other Person with respect to the Aircraft, (iv) the
invalidity or unenforceability or lack of due authorization or other infirmity
of this Lease or any other Transaction Document or document or instrument
executed pursuant hereto or thereto, or any lack of right, power or authority of
the Lessor or the Lessee or any other party to any other Transaction Document to
enter into this Lease or any other Transaction Document or any such document or
instrument, (v) any loss of or damage to the Aircraft, Airframe, any Engine or
any Part, (vi) any insolvency, bankruptcy, reorganization or similar proceedings
by or against the Lessee or any other Person, or (vii) any failure, breach or
delay by the Lessor or any other Person in performing or complying with any term
of this Lease or any other cause whether similar or dissimilar to the foregoing,
any present or future law notwithstanding, it being the intention of the parties
that all Rent payable by the Lessee hereunder shall continue to be payable in
all events in the manner and at the times provided herein. Such Rent shall not
be subject to any abatement and the payments thereof shall not be subject to any
setoff or any reduction for any reason whatsoever, including any present or
future claims of the Lessee against the Lessor or any other Person under this
Lease or otherwise. The Lessee hereby waives, and hereby agrees to waive at any
future time at the request of the Lessor, to the full extent now or then
permitted by applicable law, any and all rights that it may now have or that at
any time hereafter may be conferred upon it, by statute or otherwise, to
terminate, cancel, quit or surrender this Lease except in accordance with the
express terms hereof. Each payment of Rent made by the Lessee to the Lessor
shall be final as to the Lessor and the Lessee. The Lessee will not seek to
recover all or any part of any such payment of Rent from the Lessor for any
reason whatsoever.

                  (b) It is the intention of the parties that the Lessor and the
Agent, as assignee of the Lessor's right under this Lease pursuant to the
Aircraft Chattel Mortgage, shall be entitled to the benefits of 11 U.S.C.
Section 1110 or any analogous section of the Federal bankruptcy laws, as amended
from time to time with respect to the right to repossess the Airframe, Engines
and Parts as provided herein, and in any circumstances where more than one
construction of the terms and conditions of this Lease is possible, a
construction that would preserve such benefits shall control over any
construction that would not preserve such benefits or would render them
doubtful. To the extent consistent with the provisions of 11 U.S.C. Section 1110
or any analogous section of the federal bankruptcy laws, as amended from time to
time, it is hereby expressly agreed, that notwithstanding any other provisions
of the federal bankruptcy law, as amended from time to time, any right of the
Lessor and the Agent, as assignee of the Lessor under the Aircraft Chattel
Mortgage, to take possession of the Aircraft in compliance with the provisions
of this Lease shall not be affected by the provisions of 11 U.S.C. Section 362
or Section 363, as amended from time to time, or any analogous provisions of any
superseding statute or any power of the bankruptcy court to enjoin such taking
of possession.

                  (c) The Lessor and the Lessee hereby agree that this Lease,
including any modifications, supplements and amendments thereto, is intended to
be treated as a lease for purposes of the Internal Revenue Code, and neither the
Lessor nor the Lessee shall file any tax



                                      -78-
<PAGE>

returns in a manner or take any other action or position inconsistent with the
foregoing or with the Lessor's ownership of the Aircraft. Nothing contained in
this Lease shall be construed as conveying to the Lessee any right, title or
interest in the Aircraft except as a Lessee only. The Aircraft shall at all
times during the term of this Lease be the sole and exclusive property of the
Lessor.

                  SECTION 21. Purchase Option.

                  (a) Purchase Option. So long as no Lease Event of Default has
occurred and is continuing, the Lessee shall have the option to purchase the
Aircraft at the end of the Term for a purchase price equal to the higher of the
Fair Market Sales Value (assuming that the Aircraft are in the condition
required by the Lease) as of such date and Stipulated Loss Value plus all
accrued Rent and all Supplemental Rent then due. Upon the payment by the Lessee
of the full of such amounts, the Lessor shall convey to the Lessee all right,
title and interest of the Lessor in and to the Aircraft on an "as-is, where is"
basis, without recourse or warranty.

                  (b) Notice of Purchase. In order to exercise any purchase
option under Section 21, the Lessee shall be required to give not less than 90
days (but not more than 360 days) irrevocable prior written notice to the
Lessor. The Lessee will give the Lessor prior written irrevocable notice not
less than 90 days (but not more than 360 days) before the expiration of the Term
of its determination to return the Aircraft and not exercise any purchase option
under this Section 21. If the Lessee fails to give notice as required herein,
the Lessee will be deemed to have elected to return the Aircraft to the Lessor.

                  SECTION 22. Lessor's Right to Perform for Lessee. If the
Lessee fails to make any payment of Rent required to be made by it hereunder or
fails to perform or comply with any of its agreements contained herein, then the
Lessor may itself make such payment or perform or comply with such agreement but
shall not be obligated hereunder to do so, and the amount of such payment and
the amount of the reasonable expenses of the Lessor incurred in connection with
such payment or the performance of or compliance with such agreement, as the
case may be, together with interest thereon at the Past Due Rate, shall be
deemed Supplemental Rent, payable by the Lessee upon demand.

                  SECTION 23. Miscellaneous. (a) Any provision of this Lease
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, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. No term or
provision of this Lease may be changed, waived, discharged or terminated orally,
but only by an instrument in writing signed by the Lessor, the Lessee and the
Agent. This Lease shall constitute an agreement of lease, and nothing contained
herein shall be construed as conveying to the Lessee any right, title or
interest in the Aircraft except as a lessee only. Neither the Lessee nor any
Affili-



                                      -79-
<PAGE>

ate of the Lessee will file any tax returns in a manner inconsistent with the
foregoing fact or with the Lessor's ownership of the Aircraft or with the
parties' agreement that this Lease be treated as a tax lease for purposes of the
Internal Revenue Code. The section and paragraph headings in this Lease and the
table of contents are for convenience of reference only and shall not modify,
define, expand or limit any of the terms or provisions hereof and all reference
herein to numbered sections, unless otherwise indicated, are to sections of this
Lease. THIS LEASE HAS BEEN DELIVERED IN THE STATE OF NEW YORK AND SHALL IN ALL
RESPECTS BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF
THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES. EACH OF
THE LESSEE AND THE LESSOR HEREBY WAIVES TRIAL BY JURY IN ANY JUDICIAL PROCEEDING
TO WHICH IT IS A PARTY INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER
ARISING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO,
OR CONNECTED WITH THIS LEASE OR ANY OTHER TRANSACTION DOCUMENT OR THE
RELATIONSHIP ESTABLISHED HEREUNDER OR THEREUNDER AND WHETHER ARISING OR ASSERTED
BEFORE OR AFTER THE DATE HEREOF OR BEFORE OR AFTER THE PAYMENT, OBSERVANCE OR
PERFORMANCE OF THE LESSEE'S OR THE LESSOR'S OBLIGATIONS UNDER THIS LEASE OR ANY
OTHER TRANSACTION DOCUMENT. This Lease may be executed by the parties hereto in
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute but one and the
same instrument.

                  (b) This Lease, together with the agreements, instruments and
other documents required to be executed and delivered in connection herewith,
supersedes all prior agreements and understanding of the parties with respect to
the subject matter hereof and thereof, except any agreements referred to herein.

                  (c) The time stipulated in this Lease for all payments and
notices by the Lessee to the Lessor and for the performance of the Lessee's
other obligations under this Lease will be of the essence of this Lease.

                  SECTION 24. Security for Lessor's Obligations. In order to
secure the obligations, the Lessor has agreed in the Aircraft Chattel Mortgage,
among other things, to assign to the Agent this Lease and the Lease Supplements
and to mortgage in favor of the Agent the Aircraft, subject to the reservations
and conditions therein set forth. All rights of the Lessor hereunder are subject
to the Aircraft Chattel Mortgage and the Lessor and the Lessee agree that so
long as the lien of the Aircraft Chattel Mortgage has not been discharged in
accordance with its terms, (i) all payments hereunder shall be made to the Agent
for the benefit of Lenders to the extent of the Lenders' interest in such
payments, (ii) all notices from or to the Lessor shall be copied to the Agent
and (iii) the Lessee shall not take any actions that the Lessor would be
prohibited from taking under the terms of the Aircraft Chattel Mortgage. The
Les-

see hereby acknowledges due notice of, and consents to, such assignment and
to the creation of such mortgage and security interest. To the extent, if any,
that this Lease and any Lease Supplement constitutes chattel paper (as such term
is in effect in any applicable jurisdiction), no security interest in this Lease
or any Lease Supplement may be created through the transfer or possession of any
counterpart other than the original executed counterpart containing the receipt
therefor executed by the Agent on the signature page hereof or thereof.

Lenders and the Agent, pursuant to which the Lenders have agreed, on the terms
and conditions set forth in the Credit Agreement, to make term loans to the
Company in the principal amount of up to $300 million (the "LOANS") to enable
the Company to refinance certain indebtedness currently encumbering the Aircraft
Collateral (as defined below). The indebtedness with respect to the Loans made
by the Lenders is to be evidenced by certain promissory notes of the Company to
the order of the Lenders of even date herewith issued under and pursuant to the
Credit Agreement (such promissory notes, as they may be amended, modified,

but for the operation of the automatic stay under Section 362(a) of the United
States Bankruptcy Code), and to secure performance of all obligations and
covenants of the Company under the Credit Agreement, this Mortgage and the other
Loan Documents (all such payment and performance obligations of the Com-

Aircraft Collateral and Aircraft Related Collateral under the laws of the United
States or any State thereof.

               (i) The chief place of business and the chief executive office of
the Company is located at 538 Commons Drive, Golden, Colorado 80401.

SECTION 4.     Covenants.

               The Company hereby covenants that so long as this Mortgage is in
effect:

               (a) Liens. The Company will not directly or indirectly create,
incur, assume or suffer to exist any Lien, on or with respect to any of the
Aircraft Collateral, or Aircraft Related Collateral, title thereto or any
interest therein, except the lien of this Mortgage and Permitted Encumbrances,
including the Lease. The Company will promptly, at its own expense, take such
action as may be necessary to duly discharge any such Lien not excepted above if
the same shall arise at any time.

               (b) Taxes. The Company will pay, and hereby indemnifies the Agent
from and against, any and all fees and taxes, levies, imposts, duties, charges
or withholdings, to-
<PAGE>
                                      -8-


gether with any penalties, fines or interest thereon (any of the foregoing for
the purposes of this Section 4(b) being called a "TAX"), which may from time to
time be imposed on or asserted against the Agent or any Lender or the Airframe
or any Engine or any part thereof or interest therein by any Federal, state or
local government or other taxing authority in the United States or by any
foreign government or subdivision thereof or by any foreign taxing authority in
connection with, relating to or resulting from: (i) the Airframe or any Engine
or any part thereof of interest therein; (ii) the manufacture, purchase,
ownership, mortgaging, lease, sublease, use, storage, maintenance, sale or other
disposition of the Airframe or any Engine; (iii) any rentals or other earnings
therefor or arising therefrom or the income or other proceeds received with
respect thereto; or (iv) this Mortgage; provided, however, that there shall be
excluded from any indemnification any Lessor Tax (as defined in the Lease) and
unless the payment of any such Tax shall be a condition to the enforceability of
this Mortgage or the perfection of the lien hereof or unless proceedings shall
have been commenced to foreclose any lien which may have attached as security
for such Tax, nothing in this Section shall require the payment of any Tax so
long as and to extent that validity thereof shall be contested in good faith by
appropriate legal proceedings promptly instituted and diligently conducted and
the Company shall have set aside on its books adequate reserves with respect
thereto in accordance with generally accepted accounting principles.

               (c) Registration; Maintenance and Operation. The Company, at its
own cost and expense, (i) will be a "citizen of the United States" as defined in
Section 40102(15) of Title 49 of the United States Code; (ii) will cause
ownership of the Aircraft to be duly registered and remain duly registered in
the United States of America in the name of the Company in accordance with the
Act; and (iii) will cause the Lessee to service, repair, inspect, test,
maintain, overhaul the Airframe and each Engine and install replacement
equipment and parts on the Aircraft and each Engine (A) so as to keep the
Airframe and each Engine in such operating condition as may be required to
permit the Airframe and each Engine to be utilized in commercial operations, (B)
so as to enable the airworthiness certification of the Airframe to be maintained
in good standing at all times under the Act, except when aircraft of the same
type, model or series as the Airframe (powered by engines of the same type as
those with which the Airframe shall be equipped at the time of grounding)
registered in the United States have been grounded by the FAA; provided,
however, that if following its issuance, the United States FAA airworthiness
certificate of the Aircraft shall be withdrawn, then subject to the provisions
of Section 4(f) hereof, so long as the Company is diligently taking or causing
to be taken all necessary action to promptly correct the condition which caused
such withdrawal, no Event of Default shall arise from such withdrawal, (C) in
accordance with the Lessee's FAA-approved maintenance, inspection and
maintenance control programs, and in the same manner and with the same care used
by the Lessee with respect to the same or similar aircraft and engines owned or
operated by the Lessee so as to keep the same in as good operating condition as
when originally mortgaged hereunder, ordinary wear and tear excepted, which
practices

<PAGE>
                                      -9-

shall at all times be at or above the standard of the industry in the United
States for prudent maintenance of similar equipment, and (D) in such manner as
may be necessary to maintain in full force all warranties of the manufacturers
thereof. The Company shall maintain, or shall cause Lessee to maintain, all
records, logs and other materials which may be required to permit the Airframe
and each Engine to be so utilized.

                  The Company will comply in all material respects with all
airworthiness directives, mandatory notes or modifications or similar
requirements affecting the same (including those issued by the manufacturer or
supplier) in such condition so as to comply with the provisions of this Mortgage
and the rules and regulations of the FAA from time to time in force and
applicable to the Aircraft and Engines. Neither the Airframe nor any Engine will
be maintained, used or operated in violation of any law or any rule, regulation
or order of any government or governmental authority having jurisdiction
(domestic or foreign), or in violation of any airworthiness certificate, license
or registration relating to the Airframe or such Engine issued by any such
authority, and in the event that such laws, rules, regulations or orders require
alteration of the Airframe or any Engine, the Company, at its own cost and
expense, will conform thereto or obtain conformance therewith and will maintain
the same in proper operating condition under such laws, rules, regulations and
orders; provided, however, that the Company may, in good faith (after having
delivered to the Agent an Officer's Certificate stating the facts with respect
thereto), contest the validity or application of any such law, rule, regulation
or order in any reasonable manner which does not, in the Agent's opinion,
adversely affect the interests under this Mortgage of the Agent or any Lender.

                  The Company will not operate, use or locate the Airframe or
any Engine, (I) in any area in which any insurance required to be maintained
pursuant to Section 4(g) shall not be at the time in full force and effect, or
in any area excluded from coverage by an insurance policy in effect with respect
to the Airframe or such Engine, except in the case of a requisition for use by
the United States of America, and then only if Company obtains indemnity or "war
risk" insurance in lieu of such insurance from the United States of America
against the risks and in the amounts required by said Section covering such
area, or (II) in any recognized or threatened area of hostilities unless fully
covered to the Agent's satisfaction by war risk and political risk and allied
perils insurance or unless the Airframe or such Engine is operated or used under
contract with the Government of the United States of America under which
contract that Government provides "war risk" insurance or assumes liabilities
for any damages, loss, destruction or failure to return possession of the
Airframe or such Engine at the end of the term of such contract and for injury
to persons or damage to property of others.

                  The Company shall not use the Aircraft nor suffer it to be
used in any manner or for any purpose excepted from any of the insurance on or
in respect of the Aircraft or for the purpose of carriage of goods of any
description excepted from such insurance nor do, or
<PAGE>
                                      -10-

permit to be done, anything which, or admit to do anything the admission of
which, may invalidate any of such insurance.

                  (d) Possession. The Company will not, without the prior
written consent of the Agent, sell, assign, lease or otherwise in any manner
deliver, transfer or relinquish possession or control of, or transfer the right,
title or interest of the Company in, the Airframe or any Engine except that the
Company may enter into and perform all provisions and terms of the Lease and the
Lessee or the Company, unless a Potential Event of Default or Event of Default
shall have occurred and be continuing, without the prior written consent of the
Agent, may take the following actions so long as the actions to be taken shall
not deprive the Agent of the first priority Lien of this Mortgage on the assets
subject hereto and so long as the actions to be taken shall not deprive the
Company as Lessor of the protections of Section 1110 of the Bankruptcy Code with
respect to the Aircraft nor shall such actions deprive the Agent of the
protections of Section 1110 of the Bankruptcy Code with respect to the Aircraft
as assignee of the Company's rights under this Mortgage:

                  (i) transfer possession of the Airframe or any Engine other
         than by lease to the United States of America or any instrumentality
         thereof pursuant to the Civil Reserve Air Fleet Program (as
         administered pursuant to Executive Order 12656, or any substitute
         order) or any similar or substitute programs;

                  (ii) transfer possession of the Airframe or any Engine to the
         manufacturer thereof for testing or other similar purposes or any other
         organization for service, repairs, maintenance or overhaul or, to the
         extent permitted by Section 4(e) hereof, for alterations or
         modifications;

                  (iii) subject any Engine to normal interchange or pooling
         agreements or arrangements of the type customary in the United States
         airline industry and entered into by the Company or the Lessee in the
         ordinary course of business that do not contemplate or require the
         transfer of title to, use for the remainder of its useful life, or
         registration of the Airframe or title to, or use for the remainder of
         its useful life of such Engine; provided, however, that if the
         Company's title to or use for the remainder of its useful life, of the
         Airframe or any Engines shall be divested under any such agreement or
         arrangement, such divesture shall be deemed to be an Event of Loss with
         respect to the Airframe or such Engine and the Company shall comply
         with Section 4(f) in respect thereof;

                  (iv) install an Engine on an airframe that is owned by the
         Lessee, provided that such airframe is free and clear of all Liens on
         property of the Lessee except (A) Liens permitted under the Lease, (B)
         Liens that apply only to the engines (other than the Engines),
         appliances, parts, instruments, appurtenances, accessories, furnishings
<PAGE>
                                      -11-

         and other equipment (other than Parts) installed on such airframe (but
         not to the airframe as an entirety), and (C) the rights of any Domestic
         Air Carrier, under normal interchange agreements which are customary in
         the airline industry and do not contemplate or require the transfer of
         title to such airframe or the engines installed thereon;

                  (v) install an Engine on an airframe leased to the Lessee or
         owned by the Lessee subject to a conditional sale or other security
         agreement, provided that: (A) such airframe is free and clear of all
         Liens, except the rights of the parties to the lease or conditional
         sale or other security agreement covering such airframe and except
         Liens of the type permitted by clause (iv) above and (B) the Agent
         shall have received from the lessor, conditional vendor or secured
         party and each of the purchasers, mortgagees and encumbrancers of such
         lessor, conditional vendor or secured party of such airframe a written
         agreement (which may be the lease, conditional sale agreement or
         mortgage covering such airframe), whereby such lessor, conditional
         vendor or secured party and each of the purchasers, mortgagees and
         encumbrancers of such lessor, conditional vendor or secured party
         expressly and effectively agrees that neither it nor its successors and
         assigns will acquire or claim any right, title or interest in any
         Engine by reason of such Engine being installed on such airframe at any
         time when such Engine is subject to this Mortgage;

                  (vi) install an Engine on an airframe owned or leased by the
         Lessee subject to a conditional sale or other security agreement under
         circumstances where neither clause (iv) nor clause (v) above is
         applicable; provided, that any divesture of title to such Engine
         resulting from such installation shall be deemed to be an Event of Loss
         with respect to such Engine and the Company shall comply with Section
         4(f) in respect thereof;

                  (vii) authorize or permit the Lessee to enter into an ACMI
         Contract or wet lease for the Airframe and the Engines or engines
         installed thereon with any third party pursuant to which the Company
         has operational control of the Airframe and any Engines installed
         thereon, such operation to be performed solely by individuals under the
         operational control of the Company possessing all current certificates
         and licenses that would be required under the applicable laws of the
         United States for the performance by such employees of similar
         functions within the United States; provided, that the Company's
         obligations hereunder shall continue in full force and effect
         notwithstanding any such ACMI Contract or wet lease;

provided, however, that the rights of any transferee who receives possession of
the Airframe or any Engine permitted by the terms hereof shall be made subject
and subordinate to, and the Leases shall be made expressly subject and
subordinate to, the lien and security interest of this
<PAGE>
                                      -12-

Mortgage and all of the Agent's rights hereunder and the Company shall remain
primarily liable hereunder for the performance of all the terms of this Mortgage
to the same extent as if such transfer had not occurred, and any such instrument
of transfer shall include appropriate provisions for the maintenance and
insurance of the Airframe or such Engine, and any such instrument of transfer
(other than the Lease) shall expressly prohibit any further transfer of the
Airframe or such Engine or any assignment of the rights thereunder; and provided
further, that no such lease, pooling arrangement or other transfer or
relinquishment of the possession of the Airframe or any Engine shall in any way
discharge or diminish any of the Company's obligations to the Agent hereunder or
under the Credit Agreement. In the event that the Agent shall have received from
the lessor, conditional vendor or secured party of any airframe leased to the
Lessee or purchased by the Lessee subject to a conditional sale or other
security agreement, a written agreement complying with clause (B) of Section
4(d)(v), and the lease or conditional sale or other security agreement covering
such airframe also covers an engine, engines or spare engines owned by the
lessor under such lease, conditionally owned by the conditional vendor under
such conditional sale agreement, or subject to such security agreement, the
Agent hereby agrees for the benefit of such lessor, conditional vendor or
secured party that the Agent will not acquire or claim, as against such lessor,
conditional vendor or secured party, any right, title or interest in any such
engine or spare engine as the result of such engine or spare engine being
installed on the Airframe at any time while such engine or spare engine is
subject to such lease or conditional sale or other security agreement and owned
by such lessor, conditionally owned by such conditional vendor or subject to
such security agreement.

                  (e) Replacement and Pooling of Parts; Alterations,
Modifications and Additions.

                  (i) Except as otherwise provided in Section 4(e)(iv), the
         Company, at its own cost and expense, will promptly replace all Parts,
         that may from time to time be incorporated or installed in or attached
         to the Airframe or any Engine and that may from time to time become
         worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond
         repair or permanently rendered unfit for use for any reason whatsoever.
         In addition, in the ordinary course of maintenance, service, repair or
         testing, the Company at its own cost and expense may remove any Parts,
         whether or not worn out, lost, stolen, destroyed, seized, confiscated,
         damaged beyond repair or permanently rendered unfit for use; provided,
         that, except as otherwise provided in Section 4(e)(iv), the Company at
         its own cost and expense shall replace such Parts as promptly as
         practicable. All replacement Parts shall be owned by the Company free
         and clear of all Liens (except Permitted Encumbrances and the Lease,
         and for pooling arrangements to the extent permitted by Section
         4(e)(ii)), and shall be in as good operating condition as, and shall
         have a value and utility at least equal to, the Parts replaced assuming
         such
<PAGE>
                                      -13-

         property were in the condition and repair required to be maintained by
         the terms hereof.

                  All Parts at any time removed from the Airframe or any Engine
         shall remain the property of the Company and shall remain subject to
         the lien and security interest of this Mortgage, no matter where
         located until such time as such Parts shall be replaced by parts that
         have been incorporated or installed in or attached to the Airframe or
         any Engine and which meet the requirements for replacement parts
         specified above. Immediately upon any replacement Part becoming
         incorporated or installed in or attached to the Airframe or any Engine
         as above provided, without further act, (A) title to such replacement
         Part shall vest in and such replacement part shall become the property
         of the Company and shall become subject to the lien and security
         interest of this Mortgage and shall be deemed part of the Airframe or
         such Engine for all purposes hereof to the same extent as the property
         originally comprising, or installed on, such Airframe or such Engine,
         and (B) title to the replaced part shall no longer be the property of
         the Company and shall thereupon become free and clear of all rights of
         the Agent hereunder and shall no longer be deemed a Part hereunder.

                  (ii) Any Part removed from the Airframe or any Engine as
         provided in Section 4(e)(i) may be subjected by the Company or the
         Lessee to a normal pooling arrangement of the type customary in the
         airline industry entered into by the Lessee in the ordinary course of
         its business and entered into with Domestic Air Carriers that are not
         the subject of any bankruptcy, insolvency, or similar proceeding,
         voluntary or involuntary, provided that the Part replacing such removed
         Part shall be incorporated or installed in or attached to the Airframe
         or such Engine in accordance with Section 4(e)(i) as promptly as
         possible after the removal of such removed part. In addition, any
         replacement Part when incorporated or installed in or attached to the
         Airframe or any Engine in accordance with Section 4(e)(i) may be owned
         subject to such a pooling arrangement, provided that the Company, at
         its expense, as promptly thereafter as possible, either (A) causes such
         replacement Part to become subject to the lien and security interest of
         this Mortgage in accordance with Section 4(e)(i) by the Company's
         acquiring title thereto for the benefit of the Agent free and clear of
         all Liens (except Permitted Encumbrances and the Lease) or (B) replaces
         such replacement Part by incorporating or installing in or attaching to
         the Airframe or such Engine a further replacement Part owned by the
         Company free and clear of all Liens (except Permitted Encumbrances and
         the Lease).

                  (iii) The Company, at its own cost and expense, shall make or
         cause to be made such alterations and modifications in and additions to
         the Airframe and the Engines as may be required from time to time to
         meet the standards of the FAA or other governmental authority having
         jurisdiction; provided, that the Company may, in good
<PAGE>
                                      -14-

         faith, contest the validity or application of any such standard in any
         reasonable matter that shall not adversely affect the Lien of this
         Mortgage or Lenders' interests therein. The Company also agrees, at its
         own cost and expense, to make or cause to be made such alterations and
         modifications in and additions to the Airframe and the Engines as may
         be required from time to time to meet the standards or requirements of
         any directive issued by a manufacturer relating to the Airframe or any
         Engine. In addition, so long as no Potential Event of Default or Event
         of Default shall have occurred and be continuing, the Company, at its
         own cost and expense, may from time to time make such alterations and
         modifications in and additions to the Airframe and any Engine as the
         Company may deem desirable in the proper conduct of its business or to
         accommodate the business of the Lessee, provided that no such
         alteration, modification or addition diminishes the value or utility or
         impairs the condition or airworthiness of the Airframe or such Engine
         below the value, utility, condition or airworthiness thereof
         immediately prior to such alteration, modification or addition,
         assuming that the Airframe or such Engine were then in the condition
         and airworthiness required to be maintained by the terms of this
         Mortgage.

                  (iv) All Parts incorporated or installed in or attached to or
         added to the Airframe or any Engine as the result of such alteration,
         modification or addition shall, without further act, become the
         property of, and title to such parts shall vest in the Company and
         shall be subject to the lien and security interest of this Mortgage;
         provided, that, so long as no Potential Event of Default or Event of
         Default shall have occurred and be continuing, the Company may remove
         and not replace any such Part if it (A) is in addition to, and not in
         replacement of or in substitution for, any Part incorporated or
         installed in or attached to the Airframe or such Engine on the date
         hereof, on the date the Engine first becomes subject to the lien of
         this Mortgage, or any Part in replacement of or substitution for any
         such Part, (B) is not required to be incorporated or installed in or
         attached or added to the Airframe or such Engine pursuant to the terms
         of Section 4(c) hereof or any other provision of this Mortgage and (C)
         can be removed from the Airframe or such Engine without diminishing or
         impairing the value, utility or airworthiness that the Airframe or such
         Engine would have had at such time had such alteration, modification or
         addition not occurred, assuming that the Aircraft Collateral was
         otherwise in the condition required by this Mortgage. Upon the removal
         by the Company of any such Part, as above provided, title thereto
         shall, without further act, be free and clear of all rights of the
         Agent hereunder and such Part shall no longer be deemed a Part
         hereunder.

                  (v) The Company will ensure that, pursuant to the terms of the
         Leases, all obligations of the Company pursuant to this Section 4(e)
         shall be performed by the Lessee, at the Lessee's own cost and expense,
         and all Parts and alterations, improve-
<PAGE>
                                      -15-

         ments or modifications in and additions to the Aircraft shall become
         subject to the Lien of this Mortgage and shall be leased to the Lessee
         under the applicable Lease.

                  (f) Event of Loss.

                  (i) If an Event of Loss shall occur with respect to an
         Airframe or an Engine, the Company will promptly notify the Agent
         thereof in writing (in any event within five (5) days of such
         occurrence) and will, not later than 180 days after the receipt of
         Proceeds in connection with such Event of Loss, mortgage hereunder, by
         complying with all of the terms of subsection (ii) below and otherwise
         taking all necessary actions to provide that the Company (and the Agent
         upon foreclosure of the Company's interest in the Lease) will continue
         to be entitled to the benefits of Section 1110 of the Bankruptcy Code
         with respect to the replacement airframe or engine referred to below,
         an Acceptable Alternate Airframe or Acceptable Alternate Engine free of
         all Liens (other than Permitted Encumbrances and the Lease). Upon
         compliance with the preceding sentence within such 180-day period, the
         Agent will execute and deliver to the Company a partial release, in
         recordable form, releasing the lien of this Mortgage to the extent that
         it covers such Airframe or Engine with respect to which such Event of
         Loss has occurred. Such Acceptable Alternate Airframe or Acceptable
         Alternate Engine shall thereupon constitute an "Airframe" or an
         "Engine," as the case may be, for all purposes hereof and shall be
         deemed to constitute part of the Aircraft.

                  (ii) Whenever the Company shall subject any Airframe or Engine
         to the lien and security interest of this Mortgage (as contemplated by
         paragraph (i) above), the Company will on or prior thereto:

                           (A) deliver to the Agent and duly file for recording
                  under the Act, a Supplemental Chattel Mortgage substantially
                  in the form of Exhibit A hereto duly executed by the Company

                           purported to be secured thereby and that all action
                           required to perfect fully such security interest has
                           been taken and completed,

                                    (IV) that the Company (and the Agent upon

                           the Act.

                  (iii) With respect to the Airframe or any Engine as between
         the Agent and the Company, any payments on account of an Event of Loss

         which is provided for in Section 4(g) below and under the terms of the
         Credit Agreement) received from any government authority or other
         person shall be applied as follows:

                           (A) if such payments are received with respect to an
                  Event of Loss to an Airframe or Engine that has been or is
                  being replaced by the Company pursuant to the terms hereof, so
                  long as there shall exist no Event of Default or Potential
                  Event of Default, such payment shall be paid over to or
                  retained by the Company or the Lessee upon satisfaction of the
                  conditions for replacement contained in paragraph (ii) above
                  and until such time shall be held by the Agent in accordance
                  with the provisions hereof as security for the Secured
                  Obligations; and

                           (B) if such payments are received with respect to an
                  Event of Loss with respect to which no replacement is being
                  effected, such payments shall be applied to the prepayment of
                  the Notes required pursuant to the terms of the

                                      -18-

                  Credit Agreement and shall be held pursuant to the terms of
                  this Mortgage, and the balance, if any, shall be paid over to
                  or retained by the Company.

                           (C) In the event of a requisition for use by the
                  United States Government of the Airframe or any Engine, the
                  Company shall promptly notify the Agent of such requisition
                  and all of the Company's obligations under this Mortgage shall
                  continue to the same extent as if such requisition had not
                  occurred. Any payments received by the Agent or the Company
                  from the United States Government for the use of the Airframe
                  or such Engine, shall be paid over to, or retained by, the
                  Company.

                           (D) Any amount referred to in paragraph (iii) or (iv)
                  of this Section 4(f) that is payable to or retained by the
                  Company shall not be paid to the Company or retained by the
                  Company, if at the time of such payment or retention any Event
                  of Default or a Potential Event of Default shall have occurred
                  and be continuing, but shall be held by or paid over to the
                  Agent as security for the obligations of the Company under
                  this Mortgage and the other Loan Documents, and, if the Agent
                  shall declare the Credit Agreement to be in default, shall be
                  applied against the Company's obligations hereunder and
                  thereunder as and when due. At such time as there shall not be
                  continuing any such Event of Default or Potential Event of
                  Default, such amount shall be paid to the Company to the
                  extent not previously applied in accordance with the preceding
                  sentence. In addition, and whether or not there shall exist an
                  Event of Default or Potential Event of Default, until such
                  time as the Company shall request to be paid any amount
                  referred to in paragraph (iii) or (iv) in order to effect the
                  mortgaging hereunder of a replacement Airframe or Engine, any
                  amounts referred to in paragraphs (iii) or (iv) of this
                  Section 4(f) shall be held by the Agent as security for the
                  obligations of the Company under this Mortgage and the other
                  Loan Documents.

                  (g) Insurance.

                  (i) The Company will cause the Lessee at all times to carry
         and maintain on or with respect to the Aircraft, at the Lessee's own
         cost and expense, public liability (including without limitation,
         contractual liability, cargo liability, passenger legal liability,
         bodily injury and product liability, but excluding manufacturer's
         product liability) and property damage insurance with insurers of
         recognized responsibility and reputation in amounts, of the type and
         covering the risks customarily carried with respect to similar aircraft
         by corporations engaged in the same or similar business and similarly
         situated with the Lessee but in no event in an amount less than
         $500,000,000 per occurrence (which shall include war risk, governmental
         confiscation and expro-
<PAGE>
                                      -19-

         priation and allied perils coverage). During any period when the
         Aircraft is on the ground and not in operation, the Lessee may carry or
         cause to be carried, in lieu of insurance required by this Section,
         insurance otherwise conforming with the provisions of this Section
         except that the amounts of coverage shall not be required to exceed the
         amounts of comprehensive airline liability insurance, and the scope of
         risk covered and type of insurance shall be the same, as are
         customarily carried with respect to similar aircraft on the ground by
         corporations engaged in the same or similar business and similarly
         situated with the Lessee. Any policies of insurance carried in
         accordance with this Section 4(g) and any policies taken out in
         substitution or replacement of any such policies (A) shall be amended
         to name the Agent and the Lenders as additional named insureds, (B)
         shall be primary without right of contribution from any other insurance
         which is carried by the Lessee, (C) shall expressly provide that all
         provisions thereof, except the limits of the liability, shall operate
         in the same manner as if there were a separate policy covering each
         insured, and (D) shall provide that the insurer shall waive any right
         of subrogation against the Agent or the Lenders.

                  (ii) The Company will cause the Lessee at all times to carry
         and maintain with insurers of recognized responsibility and reputation
         on or with respect to the Aircraft, at the Lessee's own cost and
         expense, aircraft ground and flight all-risk hull insurance as well as
         fire and extended coverage insurance on Engines and other equipment
         while removed from the Airframe or airframe (which shall include war
         risk, governmental confiscation and expropriation (other than by the
         United States Government) and allied perils including (A) strikes,
         riots, civil commotions or labor disturbances, (B) any malicious act or
         act of sabotage and (C) hijacking (air piracy) or any unlawful seizure
         or wrongful exercise of control of the Aircraft or crew in flight
         (including any attempt at such seizure or control) made by any person
         or persons aboard the Aircraft or another aircraft acting without the
         consent of the insured, if and to the extent the same shall be
         maintained by the Lessee with respect to similar aircraft owned or
         operated by the Lessee on the same routes or if the Aircraft or another
         aircraft is operated on routes where the custom is for Domestic
         Carriers similarly situated with the Lessee flying comparable routes
         with similar aircraft to carry such insurance, of the type usually
         carried by corporations engaged in the same or similar business and
         similarly situated with the Lessee; provided, that such insurance
         (including any self-insurance to the extent permitted below) shall at
         all times be for an amount not less than the greater of the amount
         required by the applicable Lease and $50,000,000. During any period
         when the Aircraft is on the ground and not in operation the Lessee may
         carry or cause to be carried, in lieu of the insurance required by this
         Section, insurance otherwise conforming hereto except that the scope of
         risk covered and type of insurance shall be the same as are from time
         to time customarily carried with respect to similar aircraft or spare
         engines by corporations engaged in the same or similar
<PAGE>
                                      -20-

         business and similarly situated with the Lessee for aircraft on the
         ground in an amount at least equal to the applicable amount provided
         above. All such insurance shall name the Agent and the Lenders as
         additional insureds and loss payees to the extent their interest may
         appear and shall provide that any loss to the Airframe or an Engine in
         excess of $2,000,000 (and, if a Potential Event of Default or Event of
         Default has occurred and is continuing, any such loss) shall be payable
         to the Agent for the benefit of the Lenders; and shall be primary
         without right of contribution from any other insurance that is carried
         by the Agent with respect to its interest therein.

                  The Lessee may self-insure, by way of deductible or equivalent
         provisions in insurance policies, the risks required to be insured
         against pursuant to this Section 4(g)(ii) in such reasonable amounts as
         are then applicable to other similar aircraft or spare engines in the
         Lessee's fleet that are of a value comparable to the Aircraft, and as
         are not substantially greater than amounts self-insured by corporations
         engaged in the same or similar business and similarly situated with the
         Lessee; provided, however, that the Company shall not permit the Lessee
         to self-insure in an amount in excess of $1,000,000 without the prior
         written consent of the Agent.

                  (iii) Any policies of insurance required pursuant to either
         paragraph (i) or paragraph (ii) above shall: (A) be amended to name the
         Agent and the Lenders as additional named insureds, but without the
         Agent or the Lenders being thereby liable for premiums; (B) provide
         that in respect of the interest of the Agent or the Lenders in such
         policies the insurance shall not be invalidated by any action or
         inaction of the Lessee and shall insure the interests of the Agent and
         the Lenders regardless of any breach or violation by the Lessee or any
         Person (other than the Agent) of any warranty, declaration or condition
         contained in such policies; (C) provide that if such insurance is
         cancelled, or if any material change is made in the coverage that
         affects the interest of the Agent or any Lender, or if such insurance
         is allowed to lapse for nonpayment of premium, such cancellation,
         change or lapse shall not be effective as to the Agent for thirty (30)
         days (seven (7) days, or such shorter or longer period as may from time
         to time be customarily available in the industry, in the case of any
         war risk and allied perils coverage) after receipt by the Agent of
         written notice from such insurers of such cancellation, change or
         lapse; (D) be in full force and effect throughout any geographical
         areas at any time traversed by the Aircraft and shall be payable in
         U.S. dollars; (E) waive any right of the insurers to any setoff or
         counterclaim or any other deduction, whether by attachment or otherwise
         in respect of any liability of the Agent; and (F) waive all rights of
         subrogation against the Agent.

                  (iv) In the case of a lease or contract with the United States
         or any agency or instrumentality thereof in respect of the Airframe or
         any Engine, a valid agreement by the United States or such agency or
         instrumentality to indemnify the Lessee against
<PAGE>
                                      -21-

         the same risks against which the Lessee is required hereunder to insure
         shall be considered adequate insurance with respect to the Airframe or
         such Engine to the extent of the risks and in the amounts that are the
         subject of any such agreement to indemnify.

                  (v) On or prior to the date hereof, and annually thereafter on
         or prior to January 31, the Company will cause the Lessee to furnish to
         the Agent (A) a report signed by a firm of independent aircraft
         insurance brokers, appointed by the Lessee and not objected to by the
         Agent, describing in reasonable detail acceptable to the Agent the
         insurance then carried and maintained on or with respect to the
         Aircraft and the Engines and stating that in the opinion of such firm
         such insurance complies with the terms of this Section 4(g) and is
         adequate to protect the interests of the Lessee, the Company and the
         Agent, and (B) certificates of the insurer or insurers evidencing the
         insurance covered by the report. The Company will cause the Lessee to
         cause such brokers to advise the Agent in writing (x) promptly of any
         default in the payment of any premium and of any other act or omission
         on the part of the Lessee of which such firm has knowledge and which
         might invalidate or render unenforceable, in whole or in part, any
         insurance on the Aircraft or any Engine and (y) at least thirty (30)
         days prior to the expiration or termination date, or date of
         effectiveness of any material change, of any insurance carried and
         maintained on the Aircraft hereunder.

                  (vi) All insurance payments and other payments received by the
         Agent or the Company from insurance referred to in paragraph (ii) above
         shall be, if received by the Company, immediately paid to the Agent and
         shall be held by the Agent as security for the Secured Obligations and
         all other obligations required to be paid in accordance with the terms
         of this Mortgage and the Credit Agreement and such payments shall be
         paid to the Company upon compliance by the Company with the terms of
         Subsection 4(f) with respect to the replacement of an airframe or an
         engine, as the case may be, provided that no Potential Event of Default
         or Event of Default shall have occurred and be continuing.

                  All insurance payments and other payments received by the
         Agent or the Company from insurance referred to in paragraph (ii) above
         and paid other than as a result of an Event of Loss shall be paid by
         the Agent to or be retained by the Company, and promptly applied by the
         Company to the extent necessary to repair the damage to the Airframe or
         the Engine for which such insurance was paid, provided that the Agent
         shall not be required to make any such payment to the Company if a
         Potential Event of Default or Event of Default has occurred and is
         continuing, but shall be held or paid over to the Agent as security for
         the obligations of the Company under this Mortgage and the other Loan
         Documents, and, if the Agent shall declare the Credit Agreement to be
         in default, shall be applied against the Company's obligations
         hereunder and thereunder as and when due. Retention by the Agent of any
         amounts pursuant to the pre-
<PAGE>
                                      -22-

         ceding sentence shall not relieve the Company of its obligations to
         make promptly all repairs and replacements required by Sections 4(c)
         and (e) hereof and to pay for the same with the Company's funds or
         cause payment of the same under the Lease by the Lessee.

                  (vii) Nothing in this Section 4(g) shall prohibit the Agent or
         any Lender from obtaining insurance with respect to the Aircraft for
         its own account. The Company may, at its own expense, carry insurance
         with respect to its interest in the Aircraft in amounts in excess of
         that required to be maintained by this Section 4(g). No insurance
         maintained by the Agent or any Lender shall prevent the Company from
         causing the Lessee to carry the insurance required or permitted by this
         Section or adversely affect such insurance or the cost thereof.
         Proceeds of any such insurance carried by the Agent or any Lender shall
         be paid as provided in the insurance policy relating thereto and the
         Agent shall have no duty to obtain any such insurance.

                  (h) Inspection. The Company will permit, and cause the Lessee
to permit, any officers, employees or authorized representatives of the Agent to
inspect, at the Lessee's cost and expense under the Lease, the Aircraft
Collateral and Aircraft Related Collateral, or any part thereof, and to examine,
copy or make extracts from, any and all books, records and documents in the
possession of the Company relating to such Collateral or any part thereof and
performance of this Mortgage, all at such reasonable times and as often as may
be requested. The Agent shall have no duty to make any such inspection or
examination and shall not incur any liability or obligation by reason of making
or not making any such inspection or examination.

                  (i) Insignia. The Company shall, at its own cost and expense,
or pursuant to the Lease, cause the Airframe and each Engine included in the
Aircraft Collateral to be legibly marked (in a reasonably prominent location,
which in the case of the Airframe shall be adjacent to the airworthiness
certificate) with such a plate, disk, or other marking of customary size, and
bearing the legend "Owned by Atlas Freighter Leasing III, Inc., and Mortgaged to
Bankers Trust Company, as Agent" or such other legend, as shall in the opinion
of the Agent be appropriate or desirable to evidence the fact that it is subject
to the lien and security interest created by this Mortgage. The Company shall
not remove or deface, or permit to be removed or defaced, any such plate, disk,
or other marking or the identifying manufacturer's serial number, and, in the
event of such removal or defacement, shall promptly cause such plate, disk, or
other marking or serial number to be promptly replaced. Except as provided
above, the Company shall not allow the name of any person, association or
corporation to be placed on the Airframe or any Engine as a designation that
might be interpreted as a claim of ownership or of any security interest
therein, except that any permitted lessee may place its customary colors and
insignia or the insignia of the manufacturer on the Airframe or any Engine.

SECTION 5. Remedies.

                  (a) If any Event of Default shall occur and be continuing,
then the Agent may, without notice of any kind to the Company, exercise in
respect of the Aircraft Collateral and Aircraft Related Collateral, (i) all the
rights and remedies of a secured party on default under the Uniform Commercial
Code as in effect at the time in any applicable jurisdiction (whether or not the
Uniform Commercial Code applies to the affected Aircraft Collateral), (ii) any
and all remedies under the Leases and all of the rights and remedies of the
Lessor under the Lease, (iii) all the rights and remedies provided for in this
Mortgage, the Credit Agreement and any other Loan Document, and in any other
agreement between the Company and the Agent, and (iv) such other rights and
remedies as may be provided by law or otherwise.

                  (b) After an Event of Default has occurred and is continuing,
the Agent may, without notice, take possession of the Aircraft Collateral or any
part thereof and may exclude the Company and the Lessee, and all persons
claiming under the Company or the Lessee, wholly or partly therefrom. At the
request of the Agent, the Company shall promptly deliver or cause the Lessee to
deliver to the Agent or to whomsoever the Agent shall designate, at such time or
times and place or places as the Agent may specify, and fly or cause to be flown
to such airport or airports in the United States as the Agent may specify,
without risk or expense to the Agent, the Aircraft Collateral or any part
thereof. In addition, the Company will provide, or cause the Lessee to provide,
without cost or expense to the Agent, storage facilities for the Aircraft
Collateral. If the Company or the Lessee shall for any reason fail to deliver
the Aircraft Collateral or any part thereof after demand by the Agent, the Agent
may, without being responsible for loss or damage, (i) obtain a judgment
conferring on the Agent the right to immediate possession or requiring the
Company and the Lessee to deliver immediate possession of the Aircraft
Collateral or any part thereof to the Agent, the entry of which judgment the
Company hereby specifically consents and the Lessor's consent to which will be
obtained by the Company under the Lease, or (ii) with or without such judgment,
pursue the Aircraft Collateral or any part thereof wherever it may be found and
may enter any of the premises of the Company and the Lessee where the Aircraft
Collateral may be and search for the Aircraft Collateral and take possession of
and remove the same. The Company agrees to pay to the Agent, upon demand, all
expenses incurred in taking any such action; and all such expenses shall, until
paid, be secured by the lien of this Mortgage. Upon every such taking of
possession, the Agent may, from time to time, make all such reasonable
expenditures for maintenance, insurance, repairs, replacements, alterations,
additions and improvements to and of the Aircraft Collateral, as it may deem
proper. In each such case, the Agent shall have the right to maintain, use,
operate, store, lease, control or manage the Aircraft Collateral or any part
thereof and to carry on the business and exercise all rights and powers of
Company relating to the Aircraft Collateral, as the Agent shall deem best,
including the right to enter into any and all such agreements with respect to
the maintenance, use, operation, storage, leasing,
<PAGE>
                                      -24-

control, management or disposition of the Aircraft Collateral or any part
thereof as the Agent may determine. Further, after the occurrence and during the
continuation of an Event of Default, the Agent shall be entitled to collect and
receive directly all tolls, rents, revenues, issues, income, products and
profits of the Aircraft Collateral or any part thereof, including without
limitation, all payments under any of the Leases. Such tolls, rents, revenues,
issues, income, products and profits shall be applied to pay the expenses of the
use, operation, storage, leasing, control, management or disposition of the
Aircraft Collateral, and of all maintenance, insurance, repairs, replacements,
alterations, additions and improvements, and to make all payments that the Agent
may be required or may elect to make, if any, for taxes, assessments, or other
proper charges upon the Aircraft Collateral and all other payments that the
Agent may be required or authorized to make under any provision of this
Mortgage, as well as just and reasonable compensation for the services of the
Agent and of all persons properly engaged and employed for such purposes by the
Agent.

                  (c) The Agent, with or without taking possession of the
Aircraft Collateral, may, without notice:

                  (i) to the extent permitted by law, sell at one or more sales,
         as an entirety or in separate lots or parcels, the Aircraft Collateral
         or any part thereof, at public or private sale, at such place or places
         and at such time or times and upon such terms, including terms of
         credit (which may include the retention of title by the Agent to the
         property so sold), as the Agent may determine, whether or not the
         Aircraft Collateral shall be at the place of sale; and

                  (ii) proceed to protect and enforce its rights under this
         Mortgage by suit, whether for specific performance of any covenant
         herein contained or in aid of the exercise of any power herein granted
         or for the foreclosure of this Mortgage and the sale of the Aircraft
         Collateral under the judgment or decree of a court of competent
         jurisdiction or for the enforcement of any other right.

                  (d) After an Event of Default has occurred and is continuing,
the Company agrees to the fullest extent that it lawfully may, that it and the
Lessee will not (and hereby irrevocably waives its right to) at any time plead,
or claim the benefit or advantage of, any appraisement, valuation, stay,
extension, moratorium, or redemption law now or hereafter in force, in order to
prevent or hinder the enforcement of this Mortgage or the absolute sale of the
Aircraft Collateral. The Company, for itself and all who may claim under it,
waives, to the extent that it lawfully may, all right to have all or any portion
of the Aircraft Collateral marshalled upon any foreclosure hereof.

                  (e) Each and every remedy of the Agent shall be cumulative and
shall not be exclusive of any other remedies provided now or hereafter at law,
in equity or otherwise.
<PAGE>
                                      -25-

The Company shall reimburse the Agent, upon demand, for all fees and other
expenses paid or incurred by the Agent in exercising any rights, powers or
remedies granted hereby. All such fees and expenses shall, until paid, be
secured by the lien of this Mortgage.

                  (f) Notwithstanding anything to the contrary contained in this
Mortgage or the Lease, the Agent shall at all times have the right, to the
exclusion of the Company, to declare the Lease in default in accordance with its
terms and to exercise all remedies set forth in the Leases.

SECTION 6. Application of Proceeds.

                  The proceeds of amounts received pursuant to the Lease
(including, without limitation, amounts received in connection with the exercise
by the Lessee of any purchase option or Event of Loss) and the proceeds of any
sale, lease or other disposition of all or any of the Aircraft Collateral or
Aircraft Related Collateral under this Mortgage and all other sums realized by
the Agent pursuant to this Mortgage or any proceedings hereunder shall be
applied in the following order of priority:

                  First: To the payment of the costs and expenses of such sale,
         lease, disposition or other realization, including reasonable
         compensation to the Agent's agents and counsel, and all expenses,
         liabilities and advances made or incurred by the Agent in connection
         therewith, including, without limitation, taxes upon or with respect to
         the sale, lease, disposition or realization and the payment of taxes
         and Liens, if any, prior to the lien and security interest of this
         Mortgage (except any taxes or Liens to which the respective sale,
         lease, disposition or realization shall have been subject) and to the
         payment of expenses and the reimbursement of payments incurred or made
         by the Agent pursuant to Section 9 hereof;

                  Second: To the ratable payment of interest accrued and unpaid
         on the Notes to and including the date of such application;

                  Third: To the ratable payment of principal of the Notes, which
         payment shall be applied to the principal installments of the Notes in
         the manner specified by the Credit Agreement; and

                  Fourth: To the payment of all other amounts payable by the
         Company under the Credit Agreement, this Mortgage or any other Loan
         Document, and otherwise to the Company or to such other Person(s) as
         may lawfully be entitled, or as any court of competent jurisdiction may
         direct, the remainder.

SECTION 7. Agent as Attorney.

                  The Company hereby irrevocably appoints the Agent the true and
lawful attorney of the Company (with full power of substitution) in the name,
place and stead of, and at the expense of, the Company at any time after the
occurrence and during the continuation of an Event of Default (i) to ask,
demand, collect, sue for, recover, compound, receive and give acquittance and
receipts for moneys due and to become due under or in respect of any of the
Aircraft Collateral and Aircraft Related Collateral, (ii) to make all necessary
transfers of all or any part of the Aircraft Collateral and Aircraft Related
Collateral in connection with any sale, lease or other disposition made pursuant
hereto, (iii) to execute and deliver for value all necessary or appropriate
bills of sale, assignments and other instruments in connection with any such
sale, lease or other disposition, and (iv) generally to do, at the Agent's
option and the Company's cost and expense, at any time, or from time to time,
all acts and things that the Agent deems necessary to protect, preserve or
realize upon the Aircraft Collateral and Aircraft Related Collateral and the
Agent's security interest therein, in order to effect the intent of this
Mortgage, all as fully and effectively as the Company might do, the Company
hereby ratifying and confirming all that its said attorney (or any substitute)
shall lawfully do hereunder and pursuant hereto.

SECTION 8. Cash Collateral.

                  All monies received by the Agent to be held and applied under
this Section, and all monies if any, required to be paid to the Agent hereunder,
which disposition is not elsewhere herein otherwise specifically provided for,
shall be held by the Agent and applied from time to time as provided herein and
in the Credit Agreement and the other Loan Documents and shall be held in an
account in the name of the Agent and invested in Cash Equivalents for the
benefit and at the risk of the Company.

SECTION 9. Agent's Right to Perform.

                  If the Company fails to make any payment required to be made
by it hereunder or fails to perform or comply with any of its agreements
contained herein, the Agent may itself make such payment or perform or comply
with such agreement (including, without limitation, the agreement of the Company
to maintain insurance pursuant to Section 4(g) hereof), and the amount of such
payment and the amount of the reasonable expenses of the Agent incurred in
connection with such payment or the performance of or compliance with such
agreement, as the case may be, together with interest thereon at the rate
specified in the Credit Agreement from time to time, shall be payable by the
Company to the Agent on demand and shall constitute additional indebtedness
secured by the lien and security interest of this Mortgage.

                                      -27-

SECTION 10. Further Assurances.

                  The Company at its expense will promptly and duly execute and
deliver such documents and assurances and take such action as may be necessary
or desirable, or as the Agent may from time to time request, in order to correct
any defect, error or omission which may at any time hereafter be discovered in
the contents of this Mortgage or in the execution or delivery hereof, and/or in
order to more effectively carry out the intent and purpose of this Mortgage and
to establish, protect and perfect the rights, remedies and security interests
created or intended to be created in favor of the Agent hereunder, including,
without limitation, the execution, delivery and filing of any instruments with
the FAA and of any Uniform Commercial Code financing and continuation statements
with respect to the security interests created hereby, in form and substance
satisfactory to the Agent, in such jurisdictions as the Agent may reasonably
request. The Company hereby authorizes the Agent to file any such statements
without the signature of the Company to the extent permitted by applicable law.

SECTION 11. Continuing Security Interest.

                  This Mortgage shall create a continuing security interest in
the Aircraft Collateral and Aircraft Related Collateral and shall (a) remain in
full force and effect until the indefeasible payment in full of the Secured
Obligations, (b) be binding upon the Company, its successors and assigns and (c)
inure, together with the rights and remedies of the Agent hereunder, to the
benefit of the Agent and its successors, transferees and assigns. Without
limiting the generality of the foregoing clause (c), the Agent or any Lender
may, subject to any restrictions contained in the Credit Agreement, assign or
otherwise transfer any of its interests in the Credit Agreement or in any Note
to any other person or entity, and such other benefits in respect thereof
granted to the Agent or any Lender herein or otherwise. Upon the indefeasible
payment in full of the Secured Obligations, the security interest granted hereby
shall terminate and all rights to the Aircraft Collateral and Aircraft Related
Collateral shall revert to Company. Upon any such termination, the Agent will
execute and deliver to the Company, at the Company's expense, such instruments
of release and termination as the Company may reasonably request to evidence
such termination.

SECTION 12. Miscellaneous.

                  Any provision of this Mortgage 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, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. To the extent permitted by applicable law, the Company
hereby waives any provision of law which renders any provision hereof prohibited
or unenforceable in any respect. No term or provision of this Mortgage may be
changed, waived, discharged or
<PAGE>
                                      -28-

terminated orally, but only by an instrument in writing signed by the Company
and the Agent. The captions and headings in this Mortgage are for convenience of
reference only and shall not define or limit any of the terms or provisions
hereof.

SECTION 13. Consent to Jurisdiction and Service of Process.

                  All judicial proceedings brought against the Company with
respect to this Mortgage may be brought in any state or federal court of
competent jurisdiction in the State of New York or Colorado and by execution and
delivery of this Mortgage Company accepts for itself and in connection with the
Aircraft Collateral and Aircraft Related Collateral, generally and
unconditionally, the nonexclusive jurisdiction of the aforesaid courts and
irrevocably agrees to be bound by any judgment rendered thereby in connection
with this Mortgage. The Company hereby agrees that service of process in any
such proceeding in any such court may be made by registered or certified mail
return receipt requested to the Company at its address provided on the signature
pages of the Mortgage, such service being hereby acknowledged by the Company to
be effective and binding service in every respect. A copy of any such process so
served shall be mailed by registered mail to the Company, at its address
specified in Section 15 hereof, except that unless otherwise provided by
applicable law, any failure to mail such copy shall not affect the validity of
service of process. If any agent appointed by the Company refuses to accept
service, the Company hereby agrees that service upon it by mail shall constitute
sufficient notice. Nothing herein shall affect the right to serve process in any
other manner permitted by law or shall limit the right of the Agent to bring
proceedings against the Company in the courts of any other jurisdiction.

SECTION 14. GOVERNING LAW; TERMS.

                  THIS MORTGAGE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF
LAWS PRINCIPLES, EXCEPT AS REQUIRED BY MANDATORY PROVISION OF LAW AND EXCEPT TO
THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER,
OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR AIRCRAFT COLLATERAL ARE
GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK. Unless
otherwise defined herein or in the Credit Agreement, terms used in Article 9 of
the Uniform Commercial Code in the State of New York are used herein as therein
defined.

SECTION 15. Addresses for Notices.

                  All notices and other communications provided for hereunder

other address as shall be designated by such party in a written notice to each
other party complying as to delivery with the terms of this Section 15. All such
notices and other communications shall, when mailed, be effective when deposited
in the mails, addressed as aforesaid.

each of which shall be deemed an original and all of which together shall
constitute one and the same Mortgage.

                                 LEASE AGREEMENT


     LEASE AGREEMENT dated as of April 25, 2000, between ATLAS FREIGHTER LEASING
III, INC., a Delaware corporation (the "Lessor"), and ATLAS AIR, INC., a
Delaware corporation (the "Lessee").

                              W I T N E S S E T H :

     WHEREAS, the Lessee desires to lease from the Lessor and the Lessor is
willing to lease to the Lessee the Engines upon the terms and subject to the
conditions of this Lease;

     WHEREAS, the Lessor and the Lessee desire that this be a net lease;

     WHEREAS, the Lessor has incurred certain Loans under the Credit Agreement
in connection with the Engines to be leased pursuant to the terms of this Lease
and other aircraft and spare engines to be leased pursuant to the other Leases:

     WHEREAS, the Lessor and the Lessee desire that this Lease be, and be
treated as, a Lease for federal income tax purposes.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained
and other good and valuable consideration, the Lessor and the Lessee hereby
agree as follows:

     SECTION 1. Definitions. All capitalized terms used herein shall have the
respective meanings set forth in this section.

     "Acceptable Alternate Engine" means a General Electric CF6-80C2 engine or
an engine of the same or another manufacturer of equivalent or greater residual
value, condition, utility, airworthiness, and remaining useful life and suitable
for installation and use on one or more of the Boeing 747-400 aircraft used by
the Lessee in its business; provided, that such engine shall be an engine of a
type then being utilized by the Lessee on other Boeing 747-400 aircraft operated
by the Lessee, and shall have been maintained, serviced, repaired and overhauled
in substantially the same manner as required under this Lease without in any way
discriminating against such engine.

     "ACMI Contract" means (i) any contract entered into by the Lessee pursuant
to which the Lessee furnishes the aircraft, crew, maintenance and insurance and
customers bear all other operating expenses and (ii) any similar contract in
which the customer provides the flight crew, all substantially in accordance
with the Lessee's historical practices.


<PAGE>
                                      -2-


     "ACMI Contracted Aircraft" means an aircraft acquired by the Lessee or its
Subsidiaries and intended to be used in connection with an ACMI Contract entered
into at the time of the acquisition of such aircraft (which ACMI Contract shall
not represent a renewal or replacement of a prior ACMI Contract unless the
aircraft used pursuant to such prior ACMI Contract was operated under an
operating lease and returned to the lessor) which is in effect on the date of
calculation and has a remaining term of one year or more on the date such
aircraft was intended to be used in connection with such ACMI Contract (subject
to cancellation terms, which may include the right to cancel on six months
notice). When making any calculation on a Pro Forma Basis, effect shall be given
to the acquisition of an ACMI Contracted Aircraft by adding to the appropriate
components of Consolidated Adjusted EBITDA (i) the net projected annualized
revenues from the operation of the ACMI Contracted Aircraft under such ACMI
Contract for that portion of the period for which Consolidated Adjusted EBITDA
is being calculated prior to the acquisition of such aircraft, assuming
operation for the minimum guaranteed number of block hours (less any block hours
subject to cancellation) at the minimum guaranteed rate under such ACMI Contract
less (ii) the projected annualized cash operating expenses from such operation
for the same period for which the related projected revenues are determined in
clause (i) above; provided, that such projected cash operating expenses shall
not be less on a per block hour basis than the average historical per block hour
operating expenses of the Lessee for the four full fiscal quarters immediately
preceding the date of calculation; and provided further, that if such aircraft
is of a model other than a Boeing 747 freighter, such projected cash operating
expenses shall include maintenance costs which shall not be less than the
average for such aircraft type disclosed on the most recently available DOT
Forms 41 with respect to such aircraft type or any summary of such data as
reported in a nationally recognized industry publication. For purposes of this
definition, "ACMI Contract" shall include contracts pursuant to which the Lessee
does not pay any crew costs, in which event pro forma effect shall be given as
described above but excluding from the projected annualized cash operating
expenses all crew costs. Cash operating expenses means for purposes of this
definition consolidated operating expenses, less consolidated depreciation and
amortization and Consolidated Rental Payments, to the extent included in
computing consolidated operating expenses.

     "Affiliate" means, as applied to any Person, any other Person directly or
indirectly controlling, controlled by, or under common control with, that
Person. For the purposes of this definition, "control" (including, with
correlative meanings, the terms "controlling," "controlled by" and "under common
control with"), as applied to any Person, means the possession, directly or
indirectly, of the power to direct or cause the direction of the management and
policies of that Person, whether through the ownership of voting securities or
by contract or otherwise.

principal and interest on the Loans relating to the Engines and other unpaid
Obligations (other than principal and interest on other Loans relating to

payment shall be made on the next succeeding Business Day; provided, however,
that if any date on which a payment of Rent becomes due is not a Business Day

payment is made on such next succeeding Business Day because the original date
of payment was not a Business Day (it being understood that the amount of Basic
Rent includes Rent for such day).

          (i) each installment of Basic Rent, whether or not such installment
     has been adjusted pursuant to Section 3(b), together with all prior Basic
     Rent due and payable on such date and all accrued interest thereon shall
     be, under all circumstances and in any event, in an amount at least
     sufficient for the Lessor to pay in full principal and interest on the
     Loans relating to the Engines required to be paid by the Lessor on or
     within five Business Days of the due date of such installment of Basic
     Rent; and

          (ii) payments of Stipulated Loss Value shall be, under any
     circumstances and in any event, in an amount that (when taken together with
     any other Basic Rent due and payable in connection therewith) is at least
     equal to, as of the date of payment, the sum of the aggregate unpaid
     principal of and accrued interest on the Loans relating to the Engines and
     all other unpaid Obligations of the Lessor (other than principal and
     interest on Loans relating


<PAGE>
                                      -25-


     to aircraft or other spare engines and after taking into account all other
     payments of Stipulated Loss Value pursuant to the other Leases on such
     date).

     (f) Prepayment of Rent Payments:

          (i) In the event that the Lessor is at any time required to repay
     Loans relating to the Engines pursuant to Section 2.4C(ii) of the Credit
     Agreement, the Lessor shall notify the Lessee of such required prepayment
     and the Lessee shall immediately prepay an amount of Basic Rent equal to
     the amount of such required prepayment less any required payments of the
     Loans relating to the Engines actually made by the Lessor from Insurance
     Proceeds or Condemnation Proceeds (as each such term is defined in the
     Credit Agreement) received directly by the Lessor.

          (ii) The Lessee shall also be permitted to prepay Basic Rent
     voluntarily at any time and from time to time, without premium or penalty,
     upon not less than three Business Days' prior written or telephonic notice
     to the Lessor and the Agent.

          (iii) In the event of any prepayment pursuant to this Section 3(f),
     the schedules of Basic Rent and Stipulated Loss Value shall be adjusted so
     as to preserve the after tax yield and after tax cash flows of the Lessor
     and, to the extent consistent therewith, to minimize the net present value
     of Basic Rent payments. All such computations shall be made on the basis of
     the same assumptions and the method of computations employed in the
     original calculations of Basic Rent and Stipulated Loss Values (except to
     the extent that such assumptions have been changed as a result of such
     prepayment or any prior such adjustment). At the Lessee's written request,
     independent public accountants mutually selected by the Lessor and the
     Lessee shall confirm the required adjustments. The final determination of
     any adjustment hereunder shall be set forth in amendments to this Lease,
     executed and delivered by the Lessor, the Lessee and consented to by the
     Agent. The reasonable fees, costs and expenses of the verifying accounting
     firm shall be paid by the Lessee.

     Anything contained in the foregoing to the contrary notwithstanding, after
giving effect to the foregoing adjustments, the revised Basic Rent and
Stipulated Loss Values shall permit the Lessee to comply with Section 3(e)
hereof.

     SECTION 4. Certain Representations and Warranties. THE LESSEE ACKNOWLEDGES
AND AGREES THAT, AS BETWEEN THE LESSOR AND THE LESSEE (A) EACH ENGINE IS OF A
SIZE, DESIGN, CAPACITY AND MANUFACTURE SELECTED BY AND ACCEPTABLE TO THE LESSEE
AND THE LESSEE TAKES THE


<PAGE>
                                      -26-


SAME "AS IS," (B) THE LESSEE IS SATISFIED THAT EACH ENGINE IS SUITABLE FOR ITS
PURPOSES, (C) THE LESSOR IS NOT A MANUFACTURER OR A DEALER IN PROPERTY OF SUCH
KIND, AND (D) NEITHER THE LESSOR NOR THE AGENT NOR ANY LENDER MAKES, HAS MADE OR
SHALL BE DEEMED TO HAVE MADE, AND EACH WILL BE DEEMED TO HAVE EXPRESSLY
DISCLAIMED, ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE TITLE,
AIRWORTHINESS, VALUE, CONDITION, DESIGN, OPERATION, MERCHANTABILITY OR FITNESS
FOR USE FOR A PARTICULAR PURPOSE OF ANY ENGINE OR ANY PART THEREOF, AS TO THE
ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE
ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK, COPYRIGHT OR OTHER
PROPRIETARY RIGHT, AS TO THE ABSENCE OF OBLIGATIONS BASED ON STRICT LIABILITY IN
TORT, OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED,
WITH RESPECT TO ANY ENGINE OR ANY PART THEREOF, except that the Lessor covenants
that it will not, through its own actions or inactions, in such capacity,
interfere in the Lessee's quiet enjoyment of the Engines unless this Lease shall
have been declared or deemed to have been declared in default pursuant to
Section 17 hereof. None of the provisions of this Section 4 or any other
provision of this Lease shall be deemed to amend, modify or otherwise affect the
representations, warranties or other obligations (express or implied) of any
manufacturer, any affiliate thereof, any subcontractor or supplier of any
manufacturer or any affiliate thereof, with respect to any Engine or any Parts,
or to release the manufacturer, any affiliate thereof, or any such subcontractor
or supplier from any such representation, warranty or obligation. Unless a
Default or Lease Event of Default shall have occurred and be continuing, the
Lessor agrees to make available to the Lessee such rights as the Lessor may have
under any warranty with respect to any Engine made by the manufacturer or any
affiliate thereof or any of its subcontractors or suppliers and any other claims
against the manufacturer or any affiliate thereof, or any such subcontractor or
supplier with respect to any Engine, all pursuant to and in accordance with the
terms of any applicable purchase agreements or warranty agreements.

     SECTION 5. Lessee's Representations and Warranties. In order to induce the
Lessor to enter into this Lease and the Agent and the Lenders to make the Loans
under the Credit Agreement, the Lessee represents and warrants to the Lessor,
the Agent and each Lender on the date of this Lease that the following
statements are true, correct and complete:

          (a) Organization, Powers, Qualification, Good Standing, Business and
     Subsidiaries.

          (i) Organization and Powers. The Lessee is a corporation duly
     organized, validly existing and in good standing under the laws of the
     State of Delaware. The Lessee has all requisite corporate power and
     authority to own and operate its proper-


<PAGE>
                                      -27-


     ties, to carry on its business as now conducted and as proposed to be
     conducted, to enter into this Lease and the other Transaction Documents and
     to carry out the transactions contemplated hereby and thereby.

          (ii) Qualification and Good Standing. The Lessee is qualified to do
     business and in good standing in every jurisdiction where its assets are
     located and wherever necessary to carry out its business and operations,
     except in jurisdictions where the failure to be so qualified or in good
     standing has not had and will not have a Material Adverse Effect.

          (iii) Subsidiaries. All of the Subsidiaries of the Lessee as of the
     Initial Borrowing Date are identified on Schedule 5(a)(iii) annexed hereto.
     The capital stock of each of the Subsidiaries of the Lessee identified in
     Schedule 5(a)(iii) annexed hereto (as so supplemented) is duly authorized,
     validly issued, fully paid and nonassessable and none of such capital stock
     constitutes Margin Stock. Each of the Subsidiaries of the Lessee identified
     in Schedule 5(a)(iii) annexed hereto is a corporation duly organized,
     validly existing and in good standing under the laws of its respective
     jurisdiction of incorporation set forth therein, has all requisite
     corporate power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted, and
     is qualified to do business and in good standing in every jurisdiction
     where its assets are located and wherever necessary to carry out its
     business and operations, in each case except where failure to be so
     qualified or in good standing or a lack of such corporate power and
     authority has not had and will not have a Material Adverse Effect. Schedule
     5(a)(iii) annexed hereto correctly sets forth the ownership interest of the
     Lessee and each of its Subsidiaries in each of the Subsidiaries of the
     Lessee identified therein.

     (b) Authorization of Transaction Documents, etc.

          (i) Authorization of Transaction Documents. The execution, delivery
     and performance of this Lease and the other Transaction Documents have been
     duly authorized by all necessary corporate action on the part of the Lessee
     or its Subsidiaries, as the case may be.

          (ii) No Conflict. The execution, delivery and performance by the
     Lessee or its Subsidiaries, as the case may be, of this Lease and the other
     Transaction Documents and the consummation of the transactions contemplated
     by the Transaction Documents do not and will not (i) violate any provision
     of any law or any governmental rule or regulation applicable to the Lessee
     or any of its Subsidiaries, the certificate or articles of incorporation or
     bylaws of the Lessee or any of its Subsidiaries or any order, judgment or
     decree of any court or other agency of government binding on


<PAGE>
                                      -28-


     the Lessee or any of its Subsidiaries, (ii) conflict with in any material
     respect, result in a material breach of or constitute (with due notice or
     lapse of time or both) a material default under any material Contractual
     Obligation of the Lessee or any of its Subsidiaries, (iii) result in or
     require the creation or imposition of any Lien upon any of the properties
     or assets of the Lessee or any of its Subsidiaries (other than any Liens
     created under this Lease or any of the other Transaction Documents in favor
     of the Agent on behalf of the Lenders), or (iv) require any approval of
     stockholders or any approval or consent of any Person under any Contractual
     Obligation of the Lessee or any of its Subsidiaries, except for such
     approvals or consents as will be obtained on or before the Initial
     Borrowing Date and disclosed in writing to the Lessor and the Lenders.

          (iii) Governmental Consents. The execution, delivery and performance
     by the Lessee and its Subsidiaries, as the case may be, of this Lease and
     the other Transaction Documents and the consummation of the transactions
     contemplated by this Lease and the other Transaction Documents do not and
     will not require any registration with, consent or approval of, or notice
     to, or other action to, with or by, any federal, state or other
     governmental authority or regulatory body that has not been obtained or
     made on or prior to the date required to be obtained or made.

          (iv) Binding Obligation. This Lease and each of the other Transaction
     Documents has been duly executed and delivered by the Lessee and its
     Subsidiaries, as the case may be, to the extent that it is a party thereto,
     and is the legally valid and binding obligation of each such Person,
     enforceable against each such Person in accordance with its respective
     terms, except as may be limited by bankruptcy, insolvency, reorganization,
     moratorium or similar laws relating to or limiting creditors' rights
     generally or by equitable principles relating to enforceability.

     (c) Financial Condition.

          (A) The Lessee has heretofore delivered to the Lessor, the Agent and
     the Lenders, the following financial statements and information: the
     audited consolidated and consolidating balance sheets of the Lessee and its
     Subsidiaries as at December 31, 1999, and the related consolidated and
     consolidating statements of income, stockholders' equity and cash flows of
     the Lessee and its Subsidiaries for the fiscal year then ended. All such
     statements were prepared in conformity with GAAP and fairly present the
     financial position (on a consolidated and, where applicable, consolidating
     basis) of the entities described in such financial statements as at the
     respective dates thereof and the results of operations and cash flows (on a
     consolidated and, where applicable, consolidating basis) of the entities
     described therein for each of the periods then ended, subject, in the case
     of any such unaudited financial statements, to changes resulting from audit
     and normal year-end adjustments. Neither the Lessee nor any of


<PAGE>
                                      -29-


     its Subsidiaries has (and will not, following the Initial Borrowing Date,
     have) any Contingent Obligation, contingent liability or liability for
     taxes, long-term lease or unusual forward or long-term commitment that is
     not reflected in the foregoing financial statements or the notes thereto
     and which in any such case is material in relation to the business,
     operations, properties, assets, condition (financial or otherwise) or
     prospects of the Lessee or any of its Subsidiaries.

          (B) Except as fully disclosed in the financial statements delivered
     pursuant to Section 5(c)(A), there were as of the Initial Borrowing Date no
     liabilities or obligations with respect to the Lessee and its Subsidiaries
     of any nature whatsoever (whether absolute, accrued, contingent or
     otherwise and whether or not due) which, either individually or in
     aggregate, could reasonably be expected to be material to the Lessee and
     its Subsidiaries taken as a whole. As of the Initial Borrowing Date, the
     Lessee does not know of any basis for the assertion against it of any
     liability or obligation of any nature whatsoever that is not fully
     disclosed in the financial statements delivered pursuant to Section 5(c)(A)
     which, either individually or in the aggregate, could reasonably be
     expected to be material to the Lessee and its Subsidiaries taken as a
     whole.

          (d) No Material Adverse Change; No Restricted Junior Payments.

          Since December 31, 1999, no event or change has occurred that has
     caused or evidences, either in any case or in the aggregate, a Material
     Adverse Effect. Since December 31, 1999, neither the Lessee nor any of its
     Subsidiaries has directly or indirectly declared, ordered, paid or made, or
     set apart any sum or property for, any Restricted Junior Payment or agreed
     to do so, except as permitted by subsection 7(e) hereunder.

          (e) Title to Properties, Liens.

          The Lessee and its Subsidiaries have (i) good, sufficient and legal
     title to (in the case of fee interests in real property), (ii) valid
     leasehold interests in (in the case of leasehold interests in real or
     personal property), or (iii) good title to (in the case of all other
     personal property), all of the properties and assets reflected in the
     financial statements referred to in subsection 5(c) or in the most recent
     financial statements delivered pursuant to subsection 6(a), in each case
     except for assets disposed of since the date of such financial statements
     in the ordinary course of business or as otherwise permitted under
     subsection 7(g). Except as permitted by this Lease, all such properties and
     assets are free and clear of Liens.

                                      -30-


          (f) Litigation, Adverse Facts.

          There are no actions, suits, proceedings, arbitrations or governmental
     investigations (whether or not purportedly on behalf of the Lessee or any
     of its Subsidiaries) at law or in equity or in admiralty or before or by
     any federal, state, municipal or other governmental department, commission,
     board, bureau, agency or instrumentality, domestic or foreign, pending or,
     to the knowledge of the Lessee, threatened against or affecting the Lessee
     or any of its Subsidiaries or any property of the Lessee or any of its
     Subsidiaries that, individually or in the aggregate, could reasonably be
     expected to result in a Material Adverse Effect. Neither the Lessee nor any
     of its Subsidiaries is (i) in violation of any applicable laws that,
     individually or in the aggregate, could reasonably be expected to result in
     a Material Adverse Effect or (ii) subject to or in default with respect to
     any final judgments, writs, injunctions, decrees, rules or regulations of
     any court or any federal, state, municipal or other governmental
     department, commission, board, bureau, agency or instrumentality, domestic
     or foreign, that, individually or in the aggregate, could reasonably be
     expected to result in a Material Adverse Effect.

          (g) Payment of Taxes.

          Except to the extent permitted by subsection 6(c), all tax returns and
     reports of the Lessee and its Subsidiaries required to be filed by any of
     them have been timely filed, and all taxes, assessments, fees and other
     governmental charges upon the Lessee and its Subsidiaries and upon their
     respective properties, assets, income, businesses and franchises that are
     due and payable have been paid when due and payable. The Lessee does not
     know of any proposed tax assessment against the Lessee or any of its
     Subsidiaries that is not being actively contested by the Lessee or such
     Subsidiary in good faith and by appropriate proceedings; provided, that
     such reserves or other appropriate provisions, if any, for liabilities for
     taxes as shall be required in conformity with GAAP shall have been made or
     provided in the financial statements of the Lessee. There are no agreements
     with respect to taxes between the Lessee and any tax agency or authority.

          (h) Performance of Agreements.

          Neither the Lessee nor any of its Subsidiaries is in default in the
     performance, observance or fulfillment of any of the obligations, covenants
     or conditions contained in any of its Contractual Obligations, and no
     condition exists that, with the giving of notice or the lapse of time or
     both, would constitute such a default, except where the consequences,
     direct or indirect, of such default or defaults, if any, would not have a
     Material Adverse Effect.


<PAGE>
                                      -31-


          (i) Governmental Regulation.

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

          (j) Employee Benefit Plans.

          The Lessee maintains a qualified retirement plan under Section 401(k)
     of the Internal Revenue Code and a medical benefit plan. The Lessee's
     401(k) Plan has no unfunded liabilities in excess of $10,000,000, and the
     Lessee is in compliance with all applicable provisions and requirements of
     ERISA and the regulations and published interpretations thereunder with
     respect to each Employee Benefit Plan and has performed all of its
     obligations under such Employee Benefit Plan in all material respects. The
     Lessee has no Employee Benefit Plans, other than its 401(k) Plan and the
     medical benefit plan. The Lessee has no ERISA Affiliates that sponsor,
     maintain, contribute to or are liable with respect to any Employee Benefit
     Plans.

          (k) Certain Fees.

          No broker's or finder's fee or commission will be payable with respect
     to this Lease or any other Transaction Documents or any of the transactions
     contemplated hereby.

          (l) Environmental Protection.

          (i) All facilities and operations of the Lessee and its Subsidiaries
     are, and have been to the best of the Lessee's knowledge, in compliance in
     all material respects with all applicable Environmental Laws.

          (ii) There are no, and have been no, conditions, occurrences, or
     Hazardous Materials Activity, (a) arising at any facilities owned or
     operated by the Lessee or (b) arising in connection with the operations of
     the Lessee or any of its Subsidiaries (including the transportation of
     Hazardous Materials), which conditions, occurrences or Hazardous Materials
     Activity could reasonably be expected to form the basis of an Environmental
     Claim against the Lessee and which, individually or in the aggregate, could
     reasonably be expected to have a Material Adverse Effect.


<PAGE>
                                      -32-


          (iii) To the best of the Lessee's knowledge, there are no pending or
     threatened Environmental Claims against the Lessee or any of its
     Subsidiaries, and neither the Lessee nor any of its Subsidiaries has
     received any written notices, inquiries, or requests for information with
     respect to any Environmental Claims.

          (m) Employee Matters.

          There is no strike or work stoppage in existence or threatened
     involving the Lessee or any of its Subsidiaries that could reasonably be
     expected to have a Material Adverse Effect.

          (n) Solvency.

          The Lessee and each of its Subsidiaries is and, upon the incurrence of
     any obligations by the Lessee under the Leases, will be, after giving
     effect to the transactions contemplated hereby, Solvent.

          (o) Disclosure.

          No representation or warranty of the Lessee or any of its Subsidiaries
     contained in this Lease or any other Transaction Document or in any other
     document, certificate or written statement furnished to the Lessor, the
     Agent or the Lenders by or on behalf of the Lessee or any of its
     Subsidiaries for use in connection with the transactions contemplated by
     this Lease and the other Transaction Documents contains any untrue
     statement of a material fact or omits to state a material fact (known to
     the Lessee, in the case of any document not furnished by it) necessary in
     order to make the statements contained herein or therein not misleading in
     light of the circumstances in which the same were made. Any projections and
     pro forma financial information contained in such materials are based upon
     good faith estimates and assumptions believed by the Lessee to be
     reasonable at the time made, it being recognized by the Lessor, the Agent
     and the Lenders that such projections as to future events are not to be
     viewed as facts and that actual results during the period or periods
     covered by any such projections may differ from the projected results.
     There are no facts known (or which should upon the reasonable exercise of
     diligence be known) to the Lessee (other than matters of a general economic
     nature) that, individually or in the aggregate, could reasonably be
     expected to result in a Material Adverse Effect and that have not been
     disclosed herein or in such other documents, certificates and statements
     furnished to the Lessor, the Agent and the Lenders for use in connection
     with the transactions contemplated hereby.

          (p) Registration and Filing; Chief Executive Office.

          (1) Except for the registration of this Lease and the Lease Supplement
     with the FAA and the filing of a financing statement under the Uniform
     Commercial Code in Colorado, it is not necessary or advisable under
     Colorado law or the law of the State of New York in order to ensure the
     validity, effectiveness or enforceability of this Lease or to protect the
     rights of the Lessor in any of the Engines or any part thereof that any
     other instrument be filed, registered or recorded or that any action be
     taken, and, under Colorado law or the law of the State of New York, the
     rights of the Lessor in each of the Engines will have priority in all
     respects over the claims of all creditors of the Lessee other than certain
     claims by landlords of hangars, materialmen, mechanics and warehousemen in
     respect of the Engines that have priority under Colorado law.

          (2) The Lessee's chief executive office (as that term is defined in
     Article 9 of the Uniform Commercial Code as in effect in Colorado) is
     located at 538 Commons Drive, Golden, Colorado 80401, and the records of
     the Lessee concerning the Aircraft are maintained at such chief executive
     office or at the operations center at JFK International Airport, Building
     151, Jamaica, New York 11430, where the Lessee normally maintains aircraft
     records.

     SECTION 6. Lessee's Affirmative Covenants. The Lessee covenants and agrees
that, so long as any amounts under this Lease remain unpaid, the Lessee shall
perform, and will cause each of its Subsidiaries to perform, all covenants in
this Section 6.

          (a) Financial Statements and Other Reports.

          The Lessee will maintain, and cause each of its Subsidiaries to
     maintain, a system of accounting established and administered in accordance
     with sound business practices to permit preparation of financial statements
     in conformity with GAAP. The Lessee will deliver to the Lessor, the Agent
     and the Lenders:

               (1) Quarterly Financials: as soon as available and in any event
          within 45 days after the end of each fiscal quarter of each fiscal
          year, (a) the consolidated and consolidating balance sheets of the
          Lessee and its Subsidiaries as at the end of such fiscal quarter and
          the related consolidated and consolidating statements of income,
          stockholders' equity and cash flows of the Lessee and its Subsidiaries
          for such fiscal quarter and for the period from the beginning of the
          then current fiscal year to the end of such fiscal quarter, setting
          forth in each case in comparative form the corresponding figures for
          the corresponding periods of the previous fiscal year, all in
          reasonable detail and certi-

          present the financial condition of the Lessee and its Subsidiaries as
          at the dates indicated and the results of their operations and their
          cash flows for the periods indicated, subject to changes resulting
          from audit and normal year-end adjustments, and (b) a narrative report
          describing the operations of the Lessee and its Subsidiaries in the
          form prepared for presentation to senior management for such fiscal
          quarter and for the period from the beginning of the then current
          fiscal year to the end of such fiscal quarter; provided, that delivery

     and will cause each of its Subsidiaries to, at all times preserve and keep
     in full force and effect its corporate existence and all rights and
     franchises material to its business; provided, however, that the corporate
     existence of any such Subsidiary may be terminated if such termination is
     in the interests of the Lessee and its Subsidiaries and is not materially
     disadvantageous to the Lessor or to any assignee of the Lease. The Lessee
     will at all times maintain its corporate existence as a United States
     Citizen.

          (c) Payment of Taxes and Claims; Tax Consolidation.

          (i) The Lessee will, and will cause its Subsidiaries to, pay all
     taxes, assessments and other governmental charges imposed upon it or any of
     its properties or assets or in respect of any of its income, businesses or
     franchises before any penalty, fine or interest accrues thereon, and all
     claims (including, without limitation, claims for labor, services,
     materials and supplies) for sums that have become due and payable and that
     by law have or may become a Lien upon any of its properties or assets,
     prior to the time when any penalty fine or interest shall be incurred with
     respect thereto; provided, that no such charge or claim need be paid if
     being contested in good faith by appropriate proceedings promptly
     instituted and diligently conducted and if such reserve or other
     appropriate provision, if any, with respect to any liability for taxes, as
     shall be required in conformity with GAAP shall have been made therefor in
     the financial statements of the Lessee.

          (ii) The Lessee will not, and will not permit any of its Subsidiaries
     to, file or consent to the filing of any consolidated income tax return

     other than the Holding Company and its Subsidiaries).

          (d) Maintenance of Properties; Insurance.

          The Lessee will, and will cause its Subsidiaries to, maintain or cause
     to be maintained in good repair, working order and condition, ordinary wear
     and tear excepted, all material properties used or useful in the business
     of the Lessee and its Subsidiaries and from time to time will make or cause
     to be made all appropriate repairs,


<PAGE>
                                      -40-


     renewals and replacements thereof. The Lessee will maintain or cause to be
     maintained, with insurers of recognized responsibility and reputation,
     insurance with respect to its properties and business and the properties
     and businesses of its Subsidiaries against loss or damage (including,
     without limitation, flood insurance, if necessary or advisable) of the
     kinds customarily carried or maintained under similar circumstances by
     corporations engaged in similar businesses.

          (e) Inspection; Lender Meeting.

          The Lessee will, and will cause its Subsidiaries to, permit any
     authorized representatives designated by the Lessor, the Agent or any
     Lender to visit and inspect any of the properties of the Lessee or any of
     its Subsidiaries, including any Engine or any part thereof, and its and
     their financial and accounting records, and, with the permission of the
     Lessee, which shall not be unreasonably withheld, to make copies and take
     extracts therefrom, and to discuss its and their affairs, finances and
     accounts with its and their officers and independent public accountants
     (provided, that the Lessee may, if it so chooses, be present at or
     participate in any such discussion), all upon reasonable notice and at such
     reasonable times during normal business hours and as often as may be
     reasonably requested, provided, so long as no Lease Event of Default shall
     have occurred and be continuing, that such inspection is not disruptive to
     the Lessee's business, as reasonably determined by the Lessee. The cost of
     any such inspection shall be borne by the Lessee if an Event of Default has
     occurred and is continuing or if the Lessee is thereby shown to be in
     material breach of any of its obligations hereunder, and otherwise by the
     party making the inspection. Neither the Lessor, the Agent nor any Lender
     shall have any obligation to make any inspection. Without limiting the
     foregoing, the Lessor (or its authorized representative) may attend any
     Engine shop visit. The Lessee shall provide the Lessor not less than twenty
     days' prior written notice of any such scheduled visit; provided, that if a
     scheduled visit is to occur less than twenty days after the scheduling
     thereof, the Lessee shall provide written notice of such scheduled visit
     promptly upon the scheduling thereof. Without in any way limiting the
     foregoing, the Lessee will, upon the request of the Lessor or the Agent,
     participate in a meeting of the Agent and the Lenders once during each
     fiscal year to be held at the Lessee's corporate offices (or such other
     location as may be agreed to by the Lessee, the Lessor and the Agent) at
     such time as may be agreed to by the Lessee, the Lessor and the Agent.

          (f) Compliance with Laws, etc.

          The Lessee will, and will cause its Subsidiaries to, comply with the
     requirements of all applicable laws, rules, regulations and orders of any
     governmental authority (including, without limitation, Environmental Laws),
     noncompliance with


<PAGE>
                                      -41-


     which could reasonably be expected to cause a Material Adverse Effect or
     prevent the Lessee from performing its obligations hereunder. The Lessee
     shall not conduct, and shall not permit the conduct of, any Hazardous
     Materials Activity at any facility or at any other location that could
     reasonably be expected to form the basis of an Environmental Claim against
     the Lessee and that could reasonably be expected to have a Material Adverse
     Effect.

          (g) Lessee's Remedial Action Regarding Hazardous Materials.

          The Lessee will promptly take, and will cause each of its Subsidiaries
     promptly to take, any and all necessary remedial action in connection with
     the presence, storage, use, disposal, transportation or Release of any
     Hazardous Materials on, under or about any facility in order to comply with
     all applicable Environmental Laws and Governmental Authorizations. In the
     event that the Lessee or any of its Subsidiaries undertakes any remedial
     action with respect to any Hazardous Materials on, under or about any
     facility, the Lessee or such Subsidiary will conduct and complete such
     remedial action in compliance with all applicable Environmental Laws, and
     in accordance with the policies, orders and directives of all federal,
     state and local governmental authorities except when, and only to the
     extent that, the Lessee's or such Subsidiary's liability for such presence,
     storage, use, disposal, transportation or discharge of any Hazardous
     Materials is being contested in good faith by the Lessee or such
     Subsidiary. Notwithstanding anything to the contrary contained in this
     Lease, the Lessee and its Subsidiaries may engage in the transportation of
     Hazardous Materials in the ordinary course of business so long as such is
     conducted in compliance with all applicable Environmental Laws, and all
     other applicable laws, policies, orders, directives and regulations.

          (h) Employee Benefit Plans.

          The Lessee will not establish or permit to be established any Employee
     Benefit Plans for the Lessee or any of its employees and will not permit
     any ERISA Affiliate to establish any Employee Benefit Plan that, in either
     case, could reasonably be expected to result in a liability for the Lessee,
     under Title IV of ERISA or the minimum funding standards of Part 3 of
     Subtitle B of Title I of ERISA, in excess of $20 million.

          (i) Corporate Separateness.

          The Lessee will take all such action as is necessary to keep its
     operations separate and apart from those of the Holding Company or any of
     its Affiliates, including, without limitation, ensuring that all customary
     corporate formalities, including the maintenance of separate corporate
     records and documents and holding regular meetings, are followed. Any
     financial statements distributed to any creditors of the Lessee


<PAGE>
                                      -42-


     shall clearly establish the corporate separateness of the Lessee from the
     Holding Company and each of the Holding Company's other Subsidiaries. The
     Lessee shall not take any action or conduct its affairs in a manner that is
     likely to result in the corporate existence of the Lessee on the one hand
     and of the Holding Company or any Subsidiary of the Holding Company on the
     other hand being disregarded, or in the assets and liabilities of the
     Holding Company or any Subsidiary of the Holding Company being
     substantively consolidated with those of the Lessee in a bankruptcy,
     reorganization or other insolvency proceeding.

     SECTION 7. Lessee's Negative Covenants. The Lessee covenants and agrees
that, so long as any amounts remain owing under this Lease, the Lessee shall
perform, and shall cause each of its Subsidiaries to perform, all covenants in
this Section 7.

          (a) Indebtedness.

          The Lessee shall not, and shall not permit any of its Subsidiaries,
     directly or indirectly, to create, incur, assume or guaranty, or otherwise
     become or remain directly or indirectly liable with respect to, any

          of the Lessee; provided, that, in the case of such a merger, the

          Expenditures permitted, but not made, in any fiscal year may be
          carried forward to and made during the immediately succeeding fiscal
          year (but no amount once carried forward to the next fiscal year may
          be carried forward to any fiscal year thereafter);

     guarantor or other surety, for the obligations of the lessee under any
     lease, whether an Operating Lease or a Capital Lease (other than
     intercompany leases between the Lessee and its wholly-owned Subsidiaries,
     including the Lessor); provided, however, that the Lessee may become so
     obligated to the extent that, and only to the extent that, immediately
     after giving effect to the incurrence of liability with respect to such
     lease, the Consolidated Rental Payments at the time in effect during the

     7(j), plus Consolidated Rental Payments assumed pursuant to acquisitions
     permitted under subsection 7(g)(5).

          (j) Sales and Lease-Backs.

          The Lessee shall not, and shall not permit any of its Subsidiaries to,
     directly or indirectly, become or remain liable as lessee or as a guarantor
     or other surety with respect to any lease, whether an Operating Lease or a

     Subsidiaries has sold or transferred or is to sell or transfer to any other
     Person (other than the Lessee or any of its Subsidiaries) or (ii) that the
     Lessee or any of its Subsidiaries intends to use for substantially the same
     purpose as any other property that has been or is to be sold or transferred
     by the Lessee or any of its Subsidiaries to any Person (other than the
     Lessee or any of its Subsidiaries) in connection with such lease; provided,
     that the Lessee and its Subsidiaries may become and remain liable as
     lessee, guarantor or other surety with respect to any such lease if and to

     enter into, and remain liable under, such lease under subsection 7(i).

          The Lessee shall not, and shall not permit any of its Subsidiaries to,
     directly or indirectly, enter into or permit to exist any transaction
     (including, without limitation, the purchase, sale, lease or exchange of
     any property or the rendering of any service) with any holder of 10% or
     more of any class of equity Securities of the Lessee or with any Affiliate
     of the Lessee or of any such holder, on terms that are less favorable to
     the Lessee or that Subsidiary, as the case may be, than those that might be
     obtained at the time from Persons who are not such holders or Affiliates;
     provided, that the foregoing restriction shall not apply to (i) reasonable
     and customary fees paid to and indemnification of members of the Boards of
     Directors of the Lessee and its Subsidiaries, (ii) reasonable and customary
     salaries, bonuses and other compensation paid to and indemnification of
     employees of the Lessee or any of its Subsidiaries in accordance with past
     practice or approved by the compensation committee of the Lessee, (iii)
     performance by the Lessee of its obligations under and in accordance with
     the Services Agreement or (iv) the Holding Company Reorganization.

          (l) Disposal of Subsidiary Stock.

          The Lessee shall not:

               (1) directly or indirectly sell, assign, pledge or otherwise
          encumber or dispose of any shares of capital stock or other equity
          Securities of any of its Subsidiaries, except to qualify directors if
          required by applicable law or to a wholly-owned Subsidiary of the
          Lessee; or

               (2) permit any of its Subsidiaries directly or indirectly to
          sell, assign, pledge or otherwise encumber or dispose of any shares of
          capital stock or other equity Securities of any of its Subsidiaries
          (including such Subsidiary), except to the Lessee, another
          wholly-owned Subsidiary of the Lessee, or to qualify directors if
          required by applicable law.

               Notwithstanding the foregoing, the Lessor shall be permitted to
          issue preferred stock in an amount not to exceed $100,000 to a third
          party.

          (m) Conduct of Business.

          From and after the Initial Borrowing Date, the Lessee shall not, and
     shall not permit any of its Subsidiaries to, engage in any business other
     than the businesses engaged in by the Lessee and its Subsidiaries on the
     Initial Borrowing Date and similar or related businesses.

                                      -57-


          (n) Change of Chief Executive Office.

          The Lessee shall not, and shall not permit any of its Subsidiaries to,
     change its chief executive office without giving 30 days' prior written
     notice to the Lessor and the Agent.

     SECTION 8. Return of the Engines.

     (a) Condition Upon Return. Unless any Engine has been sold pursuant to
Section 21, if at any time the Lessee shall return any Engine to the Lessor
hereunder, the Lessee, at its own expense, will return such Engine to the Lessor
at a location specified by the Lessor to the Lessee in writing. At the time of
such return, the Lessee will cause such Engine to be in compliance with the
maintenance covenants contained in this Lease.

     At the time of such return, such Engine (A) shall have an airworthiness
certificate from the Federal Aviation Administration and shall be in full
compliance with the provisions of Federal Aviation Regulations, Part 121 (or
successor regulation), and shall be in material compliance with all applicable
FAA noise, corrosion, environmental and aging aircraft requirements, (B) shall
be free and clear of all Liens and (C) shall be in as good condition as when
originally delivered to the Lessee, ordinary wear and tear excepted, and
otherwise in the condition required to be maintained under the Lessee's
FAA-approved maintenance plan; and in all such cases the Engines shall not have
been discriminated against as compared to other engines owned or leased by the
Lessee whether by reason of its leased status or otherwise in maintenance, use,
operation or in any other manner whatsoever.

     (b) Overhaul and Repair. The Engines and all Parts shall have been, and
shall be properly documented to have been, repaired or overhauled by certified
repair stations acceptable to the FAA.

     (c) Repairs. The Lessee shall ensure that all repairs performed since the
Initial Borrowing Date on the Engines are eligible to receive approval by the
FAA (or its designee), if so required. All such repairs shall be accompanied by
all data and documentation necessary to substantiate their certification,
approval and methods of compliance, as required.

     (d) Modifications. All modifications performed since the Initial Borrowing
Date that deviate from the certified configuration and that are still in
existence on the Engines shall have approval or certification by the FAA (or its
designee) or certification if required. All such modifications shall be
accompanied by complete data and documentation necessary to substantiate their
certification and approval and methods of compliance.

                                      -58-


     (e) Airworthiness Directives. All FAA Airworthiness Directives and
amendments or changes to the Federal Aviation Regulations applicable to the
Engines or Acceptable Alternate Engines or Parts, as well as all mandatory
service bulletins applicable to any of the foregoing, shall have been
accomplished by terminating action in compliance with the issuing agency's or
the manufacturer's specific instructions, as the case may be, taking into
account, any waiver, deferral or deviation from such directives, regulations or
bulletins.

     (f) Return of the Engines. In the event that an Acceptable Alternate Engine
shall be delivered by the Lessee, the Lessee, concurrently with such delivery,
will, at no cost to the Lessor, furnish, or cause to be furnished, to the Lessor
a full warranty (as to title) bill of sale with respect to each such Acceptable
Alternate Engine, in form and substance reasonably satisfactory to the Lessor
(together with an opinion of counsel to the effect that such full warranty bill
of sale has been duly authorized and delivered and is enforceable in accordance
with its terms and that any such Acceptable Alternate Engine is free and clear
of all Liens) against receipt from the Lessor of a bill of sale evidencing the
transfer, without recourse or warranty by the Lessor to the Lessee or its
designee of all of the Lessor's right, title and interest in and to any Engine
for which the Acceptable Alternate Engine was substituted.

     (g) Deferred Maintenance. There shall be no open, outstanding or deferred
maintenance items, scheduled or unscheduled, against any of the Engines
including those identified in pre-delivery inspections or test flights.

     (h) Corrosion Treatment. At the time of return, each of the Engines shall
have been maintained by cleaning and treating all mild and moderate corrosion
and correcting of all severe or exfoliate corrosion in accordance with the
Lessee's approved maintenance program or manufacturer's structural repair
manual.

     (i) Manuals. Upon the return of the Engines upon any termination of this
Lease, the Lessee shall deliver or cause to be delivered to the Lessor all logs,
manuals and data and maintenance, inspection, modification and overhaul records
and similar records required to be maintained with respect to the Engines and
Parts under FAA rules and the Engine maintenance program (the "Technical
Records"). If any such logs, manuals, records or other data are missing,
incomplete or otherwise not in accordance with FAA standards applicable to the
Lessee, the Lessee shall re-accomplish the maintenance tasks necessary to
produce such records in accordance with its approved maintenance program prior
to delivery of the Engines or otherwise perform all necessary acts (without
regard to any applicable waivers or deferrals) to obtain such records in a
manner satisfactory to the FAA and the Lessor.

     (j) Storage Upon Return. If, at least 15 days prior to termination of this
Lease at the end of the Term or pursuant to Section 17, the Lessee receives from
the Lessor a written request for storage of any Engine upon its return
hereunder, the Lessee will provide


<PAGE>
                                      -59-


the Lessor, or cause the Lessor to be provided, with storage facilities for such
Engine at the Lessee's risk and at the Lessee's expense for a period not
exceeding 30 days, and thereafter at the Lessor's risk and at the Lessor's cost
for insurance, maintenance and the Lessee's out-of-pocket expenses for such
storage for a period not exceeding 90 days (provided, that if such termination
occurs as a result of a Lease Event of Default hereunder, such storage shall be
at the cost of the Lessee), commencing on the date when such Engine is returned
substantially in the condition required under this Section 8, at a location in
the continental United States selected by the Lessee and used by the Lessee as a
location for the long-term storage of engines.

     (k) Severable Parts. At any time that any Engine is to be returned to the
Lessor, the Lessee shall, at the Lessor's request, advise the Lessor of the
nature and condition of all severable nonproprietary Parts (other than Parts
otherwise required by Sections 10 or 11 to be maintained on the Engine) owned by
the Lessee that have been used by the Lessee during the prior six months and
that the Lessee has or intends to remove from the Engine in accordance with
Section 11 hereof. The Lessor may, at its option, upon 30 days notice to the
Lessee, purchase any or all of such nonproprietary Parts from the Lessee upon
the expiration of the Term at their fair market value.

     (l) Survival. The obligations of the Lessee to comply with the terms of
this Section 8 shall survive the expiration or other termination of this Lease.

     (m) Deregistration and Export. At such time as the Lessee is obligated to
redeliver any Engine to the Lessor pursuant to this Lease, the Lessee shall at
its expense upon the request of the Lessor:

          (i) promptly take all such steps (not including procuring the
     discharge of any Lessor's Liens) as may be necessary to cancel the existing
     registration of each Engine (subject to the Lessor giving, or procuring
     that any mortgagee of the Engine gives, such notices and/or required
     consents to the cancellation of such registration) and obtain and deliver
     to the Lessor all certificates relating to the Engine required by
     applicable law on any transfer of or alteration to the registration
     thereof;

          (ii) provide to the Lessor all assistance as the Lessor may reasonably
     request so as to enable the Lessor to obtain any documents (including,
     without limitation, any export certificate of airworthiness) required by
     applicable law in relation to the export of such Engine from the state of
     registration or such other country in which such Engine is for the time
     being located and shall re-assign or otherwise confirm to the Lessor the
     benefit of any indemnities or warranties available to the Lessee from the
     manufacturer or any other supplier or manufacturer of such Engine or any
     Part; and


<PAGE>
                                      -60-


          (iii) provide to the Lessor such assistance with respect to
     information and documentation as the Lessor may reasonably require so as to
     enable such Engine to be registered and certified as to airworthiness under
     any applicable laws and/or regulations of any country other than the state
     of registration; provided, that the Lessor shall reimburse, the Lessee for
     its reasonable out-of-pocket expenses incurred in providing such
     assistance.

     SECTION 9. Liens. The Lessee will not directly or indirectly create, incur,
assume or suffer to exist any Lien, on or with respect to any of the Engines,
title thereto or any interest therein, except the lien of the Aircraft Chattel
Mortgage and Permitted Encumbrances. The Lessee will promptly, at its own
expense, take such action as may be necessary to duly discharge any such Lien
not excepted above if the same shall arise at any time.

     SECTION 10. Registration, Maintenance and Operation; Possession and
Subleases; Insignia.

     (a) Maintenance and Operation. The Lessee, at its own cost and expense,
until the expiration or earlier termination of this Lease, (i) will be a
"citizen of the United States" as defined in Section 40102(15) of Title 49 of
the United States Code and will be an air carrier certificated under Sections
401 and 609 of the Federal Aviation Act and hold all necessary air carrier
operating certificates; (ii) will cause ownership of the Engines to be duly
registered and remain duly registered with the FAA in the name of the Lessor in
accordance with the Federal Aviation Act and otherwise registered under all
applicable laws of the United States so as to be eligible to operate in
commercial air service under the Federal Aviation Act; and (iii) will service,
repair, inspect, test, maintain and overhaul each Engine, install replacement
equipment and parts on each Engine and maintain the Technical Records (A) so as
to keep each Engine in such operating condition as may be required to permit
each Engine to be utilized in commercial operations in the United States, (B) in
accordance with the Lessee's FAA-approved maintenance, inspection and
maintenance control programs, and in the same manner and with the same care used
by the Lessee with respect to the same or similar engines owned or operated by
the Lessee so as to keep the same in as good operating condition as when
originally leased hereunder, ordinary wear and tear excepted, which practices
shall at all times be at or above the standard of the industry in the United
States for prudent maintenance of similar equipment, (C) in such manner as may
be necessary to maintain in full force all warranties of the manufacturers
thereof, and (D) to enable the Lessee to deliver the Engines to the Lessor in
accordance with Section 8. The Lessee shall maintain all records, logs and other
materials that may be required to permit each Engine to be so utilized.

     The Lessee will comply in all material respects with all airworthiness
directives, mandatory notes or modifications or similar requirements affecting
the same (including those issued by the manufacturer or supplier) in such
condition so as to comply with this


<PAGE>
                                      -61-


Lease and the rules and regulations of the FAA from time to time in force and
applicable to the Engines. No Engine will be maintained, used or operated in
violation of any law or any rule, regulation or order of any government or
governmental authority having jurisdiction (domestic or foreign), or in
violation of any airworthiness certificate, license or registration relating to
such Engine issued by any such authority, and in the event that such laws,
rules, regulations or orders require alteration of any Engine, the Lessee, at
its own cost and expense, will conform thereto or obtain conformance therewith
and will maintain the same in proper operating condition under such laws, rules,
regulations and orders, provided, however, that the Lessee may, in good faith
(after having delivered to the Lessor and the Agent an Officers' Certificate
stating the facts with respect thereto), contest the validity or application of
any such law, rule, regulation or order in any reasonable manner that does not,
in the Lessor's and the Agent's opinion (in their sole discretion), adversely
affect the interests of the Lessor, the Agent or any Lender.

     The Lessee covenants and agrees with the Lessor that, the better to ensure
the availability of the benefits of Section 1110 of the Bankruptcy Code, the
Lessee shall not object to any motion, petition or application filed by the
Lessor with any bankruptcy court having jurisdiction over the Lessee, solely as
to the portion thereof that seeks, and to the extent that such motion, petition
or application seeks, a determination that such Section 1110 of the Bankruptcy
Code applies to the lease of the Engines hereunder. In the event that Section
1110 is amended, or if it is repealed and another statute is enacted in lieu
thereof, the Lessor and the Lessee (at the Lessee's expense) agree to amend this
Lease and take such other action not inconsistent with this Lease as the Lessor
reasonably deems necessary so as to afford to the Lessor the rights and benefits
as such amended or substituted statute confers upon owners, lessors and
conditional vendors of aircraft engines similarly situated to the Lessor.

     The Lessee will not operate, use or locate any Engine, (I) in any area in
which any insurance required to be maintained pursuant to Section 14 shall not
be at the time in full force and effect, or in any area excluded from coverage
by an insurance policy in effect with respect to such Engine, except in the case
of a requisition for use by the United States of America, and then only if the
Lessee obtains indemnity in lieu of such insurance from the United States of
America against the risks and in the amounts required by said Section covering
such area, or (II) in any recognized or threatened area of hostilities unless
such Engine is operated or used under contract with the Government of the United
States of America under which contract that Government assumes liabilities for
any damages, loss, destruction or failure to return possession of such Engine at
the end of the term of such contract and for injury to persons or damage to
property of others.

     The Lessee shall not use any Engine nor suffer it to be used in any manner
or for any purpose excepted from any of the insurance on or in respect of the
Engine or for the purpose of carriage of goods of any description excepted from
such insurance nor do, or per-


<PAGE>
                                      -62-


mit to be done, anything which, or omit to do anything the omission of which,
may invalidate any of such insurance.

     (b) Possession. The Lessee will not, without the prior written consent of
the Agent and the Lessor, sell, assign, lease or otherwise in any manner
deliver, transfer or relinquish possession or control of, or transfer the right,
title or interest of the Lessee in, any Engine except that, unless a Default or
Lease Event of Default shall have occurred and be continuing, the Lessee may,
without the prior written consent of the Agent and the Lessor, take the
following actions so long as the actions to be taken shall not deprive the Agent
of the first priority Lien under the Aircraft Chattel Mortgage in the assets
subject thereto and so long as the actions to be taken shall not deprive the
Lessor of the protections of Section 1110 of the Bankruptcy Code with respect to
the any Engine and shall not deprive the Agent of the protections of Section
1110 of the Bankruptcy Code with respect to the any Engine as assignee of the
Lessee's rights under this Lease pursuant to the Aircraft Chattel Mortgage:

          (i) transfer possession of any Engine other than by lease to the
     United States of America or any instrumentality thereof pursuant to the
     Civil Reserve Air Fleet Program (as administered pursuant to Executive
     Order 12656, or any substitute order) or any similar or substitute
     programs;

          (ii) transfer possession of any Engine to the manufacturer thereof for
     testing or other similar purposes or any other organization for service,
     repairs, maintenance or overhaul or, to the extent permitted by Section 11
     hereof, for alterations or modifications;

          (iii) subject any Engine to normal interchange or pooling agreements
     or arrangements of the type customary in the United States airline industry
     and entered into by the Lessee in the ordinary course of business that do
     not contemplate or require the transfer of title to or use for the
     remainder of its useful life of such Engine; provided, however, that if the
     Lessee's title to or use for the remainder of its useful life of any Engine
     shall be divested under any such agreement or arrangement, such divesture
     shall be deemed to be an Event of Loss with respect to such Engine and the
     Lessee shall comply with Section 13 in respect thereof;

          (iv) install any Engine on an airframe that is owned by the Lessee
     free and clear of all Liens except (A) those permitted under clauses (i) or
     (ii) of the definition of Permitted Encumbrances in the Credit Agreement,
     (B) those that apply only to the engines (other than the Engines),
     appliances, parts, instruments, appurtenances, accessories, furnishings and
     other equipment (other than Parts) installed on such airframe (but not to
     the airframe as an entirety), and (C) the rights of any Domestic Air
     Carrier, under normal interchange agreements that are customary in the
     airline industry and do


<PAGE>
                                      -63-


     not contemplate or require the transfer of title to such airframe or the
     engines installed thereon;

          (v) install any Engine on an airframe leased to the Lessee or owned by
     the Lessee subject to a conditional sale or other security agreement,
     provided that: (A) such airframe is free and clear of all Liens, except for
     the rights of the parties to the lease or conditional sale or other
     security agreement covering such airframe and except for Liens of the type
     permitted by clause (iv) above; and (B) the Agent and the Lessor shall have
     received from the lessor, conditional vendor or secured party and each of
     the purchasers, mortgagees and encumbrancers of such lessor, conditional
     vendor or secured party of such airframe a written agreement (which may be
     the lease, conditional sale agreement or mortgage covering such airframe),
     whereby such lessor, conditional vendor or secured party and each of the
     purchasers, mortgagees and encumbrancers of such lessor, conditional vendor
     or secured party expressly and effectively agrees that neither it nor its
     successors and assigns will acquire or claim any right, title or interest
     in any Engine by reason of such Engine being installed on such airframe at
     any time when such Engine is subject to the Aircraft Chattel Mortgage;

          (vi) install any Engine on an airframe owned by the Lessee, leased by
     the Lessee or owned by the Lessee subject to a conditional sale or other
     security agreement under circumstances where neither clause (iv) nor clause
     (v) above is applicable; provided, that any divesture of title to such
     Engine resulting from such installation shall be deemed to be an Event of
     Loss with respect to such Engine and the Lessee shall comply with Section
     13 in respect thereof;

          (vii) enter into an ACMI Contract or wet lease for any Engine with any
     third party pursuant to which the Lessee has operational control of such
     Engine, such operation to be performed solely by individuals under the
     operational control of the Lessee possessing all current certificates and
     licenses that would be required under the applicable laws of the United
     States for the performance by such employees of similar functions within
     the United States; provided, that the Lessee's obligations hereunder shall
     continue in full force and effect notwithstanding any such ACMI Contract or
     wet lease; and

          (viii) replace any Engine in accordance with Section 9.21 of the
     Credit Agreement;

provided, however, that the rights of any transferee (other than with respect to
any transactions referred to in paragraph (viii) above) who receives possession
of any Engine permitted by the terms hereof shall be made subject and
subordinate to, and any lease permitted by this Section 10(b) shall be made
expressly subject and subordinate to, the Lease and the lien and


<PAGE>
                                      -64-


security interest of the Aircraft Chattel Mortgage and all of the Agent's rights
thereunder and the Lessee shall remain primarily liable hereunder for the
performance of all the terms of the Lease to the same extent as if such transfer
had not occurred, and any such instrument of transfer shall include appropriate
provisions for the maintenance and insurance of such Engine, and any such
instrument of transfer shall expressly prohibit any further transfer of such
Engine or any assignment of the rights thereunder; and provided further, that no
such lease, pooling arrangement or other transfer or relinquishment of the
possession of any Engine shall in any way discharge or diminish any of the
Lessee's obligations to the Lessor hereunder.

     (c) Insignia. The Lessee shall, at its own cost and expense, cause each
Engine to be legibly marked with such a plate, disk, or other marking of
customary size, and bearing the legend "Owned by Atlas Freighter Leasing III,
Inc., and Mortgaged to Bankers Trust Company, as the Agent" or such other
legend, as shall in the opinion of the Lessor and the Agent be appropriate or
desirable to evidence the fact that it is subject to the ownership of the Lessor
and the lien and security interest created by the Aircraft Chattel Mortgage. The
Lessee shall not remove or deface, or permit to be removed or defaced, any such
plate, disk, or other marking or the identifying manufacturer's serial number,
and, in the event of such removal or defacement, shall promptly cause such
plate, disk, or other marking or serial number to be promptly replaced. Except
as provided above, the Lessee shall not allow the name of any person,
association or corporation to be placed on any Engine as a designation that
might be interpreted as a claim of ownership or of any security interest
therein, except that the Lessee or any permitted lessee may place its customary
colors and insignia or the insignia of the manufacturer on any Engine.

     (d) Holding Out. The Lessee agrees that it will not at any time represent
or hold out the Lessor, the Agent, any Lender or any Affiliate of any of them
(and will use its best efforts to ensure that none of the Lessor, the Agent, any
Lender or any Affiliate of any of them is not at any time represented or held
out) as being in any way connected or associated with any operation of any
Engine or any Part or any other operations or carriage undertaken by the Lessee.

     (e) No Pledging of Credit. The Lessee is not authorized to, and agrees that
it will not purport to, pledge the credit of the Lessor, any Lender or the Agent
for any maintenance, service, repairs, or overhauls of, modifications to, or
changes or alterations in, any Engine or any Part, or for any other purpose
whatsoever.

     (f) Title. Title to each of the Engines shall remain vested in the Lessor
subject to the Aircraft Chattel Mortgage and any assignments, charges or other
disposals that the Lessor may make in accordance with this Lease. The Lessee
shall not do or knowingly permit to be done anything that would jeopardize the
rights of the Lessor as owner of, or the rights of any Lender in, any of the
Engines and shall cause to be taken all actions necessary or


<PAGE>
                                      -65-


reasonably requested by the Lessor to prevent the rights of the Lessor and the
Lenders in the Engines from being jeopardized. The Lessee shall not hold itself
out to any third party as the owner of the Engines or any part thereof, and when
any third party inquires as to ownership of any Engine or any part thereof, it
will make clear to such third party that title to the same is held by the Lessor
and that such Engine is mortgaged to the Lenders. Without limiting the
foregoing, if at any time subsequent to the initial registration of the Engines,
any filing, recording or act is necessary or reasonably requested by the Lessor
to perfect, protect and preserve the rights and interests of the Lessor in any
of the Engines and the rights and interests of any Lender under the Aircraft
Chattel Mortgage, the Lessee, at its own cost and expense, will procure that
such filings, recordings and acts are done pursuant to applicable laws. At the
reasonable request of the Lessor, the Lessee shall furnish to the Lessor an
opinion of counsel or other evidence satisfactory to the Lessor of each such
filing, recordation and act. The Lessor will reimburse the Lessee for its
reasonable out-of-pocket expenses incurred in complying with its obligations
under this Section 10(f) insofar as they relate to any Lender; provided, that,
to the extent that such expenses relate to (i) any reregistration of the Engines
under Section 8 or any sublease of the Engines, (ii) any Event of Default or
(iii) any substitution of Parts or Engines pursuant to the terms hereof, the
Lessor shall not be obligated to reimburse the Lessee for such increase in
expense.

     (g) Information and Records. The Lessee shall:

          (i) promptly furnish to the Lessor all such information as the Lessor
     may from time to time reasonably request regarding any Engine or any part
     thereof, its use, location and condition;

          (ii) keep, or procure that there are kept, the Technical Records and
     shall keep as part thereof accurate, complete and current records of all
     Flight Hours and Cycles of each Engine and the Parts, and of all
     maintenance and repairs carried out on each Engine and every Part;

          (iii) procure that the Technical Records shall be kept and maintained
     in English and in such manner, form and location as the FAA and any
     applicable law may from time to time require and shall disclose the
     location of all Engines and Parts, which Technical Records, unless
     otherwise required by applicable law, shall be the property of the Lessor;

          (iv) make the Technical Records available to the Lessor (or any
     authorized representative of the Lessor) for examination during normal
     business hours (or at such other time as the Lessee and the Lessor shall
     mutually agree) upon giving reasonable written notice, provided that, so
     long as no Event of Default shall have occurred and be continuing, such
     examination does not impede the normal commercial operation of


<PAGE>
                                      -66-


     the Engines, and provided further that the cost of any such inspection
     shall be borne by the Lessee if the Lessee is thereby shown to be in breach
     of its material obligations hereunder, and otherwise by the party making
     the inspection; and

          (v) promptly on, but in no event later than three Business Days after,
     becoming aware of the same, notify the Lessor of: (I) any Total Loss with
     respect to any Engine, (II) any loss, theft, damage or destruction to any
     Engine or any part thereof if the potential cost of repairs or replacement
     may exceed $2,000,000, (III) any loss, arrest, hijacking, confiscation,
     seizure, requisitioning, impounding, taking in execution, detention or
     forfeiture of any Engine or any part thereof and (IV) any event in respect
     of any of the Engines that might reasonably be expected to involve the
     Lessor, the Lessee, the Agent or any Lender in any loss or liability.

     SECTION 11. Replacement and Pooling of Parts; Alterations, Modifications
and Additions.

     (a) Except as otherwise provided in Section 11(d), the Lessee, at its own
cost and expense, will promptly replace all Parts, which may from time to time
be incorporated or installed in or attached to any Engine and which may from
time to time become worn out, lost, stolen, destroyed, seized, confiscated,
damaged beyond repair or permanently rendered unfit for use for any reason
whatsoever. In addition, in the ordinary course of maintenance, service, repair
or testing, the Lessee at its own cost and expense may remove any Parts, whether
or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond
repair or permanently rendered unfit for use; provided, that, except as
otherwise provided in Section 11(d), the Lessee at its own cost and expense
shall replace such Parts as promptly as practicable. All replacement Parts shall
be owned by the Lessor free and clear of all Liens (except Permitted
Encumbrances and for pooling arrangements to the extent permitted by Section
11(b)), and shall be in as good operating condition as, and shall have a value
and utility at least equal to, the Parts replaced, assuming that such parts were
in the condition and repair required to be maintained by the terms hereof.

     All Parts at any time removed from any Engine shall remain the property of
the Lessor and shall remain subject to the lien and security interest of the
Aircraft Chattel Mortgage, no matter where located, until such time as such
Parts shall be replaced by parts that have been incorporated or installed in or
attached to any Engine and that meet the requirements for replacement parts
specified above. Immediately upon any replacement Part becoming incorporated or
installed in or attached to any Engine as above provided, without further act,
(A) title to such replacement Part shall vest in and such replacement part shall
become the property of the Lessor and shall become subject to this Lease and the
lien and security interest of the Aircraft Chattel Mortgage and shall be deemed
part of such Engine for all purposes hereof to the same extent as the property
originally comprising, or installed on, such


<PAGE>
                                      -67-


Engine, and (B) title to the replaced part shall no longer be the property of
the Lessor and shall thereupon become free and clear of all rights of the Lessor
hereunder and all rights derivative of the Lessor's and shall no longer be
deemed a Part hereunder.

     (b) Any Part removed from any Engine as provided in Section 11(a) may be
subjected by the Lessee to a normal pooling arrangement of the type customary in
the airline industry entered into by the Lessee in the ordinary course of its
business and entered into with Domestic Air Carriers that are not the subject of
any bankruptcy, insolvency, or similar proceeding, voluntary or involuntary;
provided, that the Part replacing such removed Part shall be incorporated or
installed in or attached to such Engine in accordance with Section 11(a) as
promptly as possible after the removal of such removed part. In addition, any
replacement Part when incorporated or installed in or attached to any Engine in
accordance with Section 11(a) may be owned by any third party subject to such a
pooling arrangement, provided that the Lessee, at its expense, as promptly
thereafter as possible, either (A) causes such replacement Part to become
property of the Lessor and subject to the lien and security interest of the
Aircraft Chattel Mortgage in accordance with Section 11(a) free and clear of all
Liens (except Permitted Encumbrances and the Aircraft Chattel Mortgage relating
to the Engine) or (B) replaces such replacement Part by incorporating or
installing in or attaching to such Engine a further replacement Part owned by
the Lessee which shall become the property of the Lessor subject to the lien and
security interest of the mortgage free and clear of all Liens (except Permitted
Encumbrances and the Aircraft Chattel Mortgage relating to the Engine).

     (c) The Lessee, at its own cost and expense, shall make or cause to be made
such alterations and modifications in and additions to each of the Engines as
may be required from time to time to meet the standards of the FAA or other
governmental authority having jurisdiction; provided, that the Lessee may, in
good faith, contest the validity or application of any such standard in any
reasonable manner that shall not adversely affect the Lessor's or the Agent's
respective interests. The Lessee also agrees, at its own cost and expense, to
make or cause to be made such alterations and modifications in and additions to
the Engines as may be required from time to time to meet the standards or
requirements of any directive issued by a manufacturer relating to any Engine.
In addition, so long as no Default or Lease Event of Default shall have occurred
and be continuing, the Lessee, at its own cost and expense, may from time to
time make such alterations and modifications in and additions to any Engine as
the Lessee may deem desirable in the proper conduct of its business, provided
that no such alteration, modification or addition diminishes the value or
utility or impairs the condition or airworthiness of such Engine below the
value, utility, condition or airworthiness thereof immediately prior to such
alteration, modification or addition, assuming that such Engine were then in the
condition and airworthiness required to be maintained by the terms of this
Lease.


<PAGE>
                                      -68-


     (d) All Parts incorporated or installed in or attached to or added to any
Engine as the result of such alteration, modification or addition shall, without
further act, become the property of, and title to such parts shall vest in the
Lessor and shall be subject to the lien and security interest of the Aircraft
Chattel Mortgage; provided, that, so long as no Default or Lease Event of
Default shall have occurred and be continuing, the Lessee may remove and not
replace any such Part if it (A) is in addition to, and not in replacement of or
in substitution for, any Part incorporated or installed in or attached to such
Engine on the date hereof, or any Part in replacement of or substitution for any
such Part, (B) is not required to be incorporated or installed in or attached or
added to such Engine pursuant to the terms of Section 10(a) hereof or any other
provision of this Lease or the Aircraft Chattel Mortgage and (C) can be removed
from such Engine without diminishing or impairing the value, utility or
airworthiness that the such Engine would have had at such time had such
alteration, modification or addition not occurred, assuming that such Engine was
otherwise in the condition required by this Lease and the Aircraft Chattel
Mortgage. Upon the removal by the Lessee of any such Part, as above provided,
title thereto shall, without further act, be free and clear of the interests of
the Lessor and all rights derivative of the Lessor's and such Part shall no
longer be deemed a Part hereunder.

     (e) In no event shall the Lessor bear any liability or cost whatsoever for
(i) any alteration or modification of, or addition to, any Engine, (ii) any
grounding of any Engine, (iii) suspension of certification of any Engine, or
(iv) loss of revenue suffered by the Lessee for any reason whatsoever.

     SECTION 12. Indemnities.

     (a) The Lessee will pay, and hereby indemnifies, on an after-tax basis, the
Lessor and its assignees, if any, from and against, any and all fees and taxes,
levies, imposts, duties, charges or withholdings, together with any penalties,
fines or interest thereon (any of the foregoing for the purposes of this Section
12 being called a "Tax"), that may from time to time be imposed on or asserted
against the Lessor and its assignees, if any, or any Engine or any part thereof
or interest therein by any federal, state or local government or other taxing
authority in the United States or by any foreign government or subdivision
thereof or by any foreign taxing authority in connection with, relating to or
resulting from: (i) any Engine or any part thereof or interest therein, (ii) the
manufacture, purchase, ownership, mortgaging, lease, sublease, use, storage,
maintenance, sale or other disposition of any Engine, (iii) any rentals or other
earnings therefor or arising therefrom or the income or other proceeds received
with respect thereto, or (iv) this Lease or the Aircraft Chattel Mortgage;
provided, however, that there shall be excluded from any indemnification under
this Section 12(a) any Lessor Tax unless the payment of any such Tax shall be a
condition to the enforceability of the Aircraft Chattel Mortgage or the
perfection of the lien thereof or unless proceedings shall have been commenced
to foreclose any lien that may have attached as security for such Tax,


<PAGE>
                                      -69-


nothing in this Section shall require the payment of any Tax so long as and to
the extent that the validity thereof shall be contested in good faith by
appropriate legal proceedings promptly instituted and diligently conducted and
the Lessee shall have set aside on its books adequate reserves with respect
thereto in accordance with generally accepted accounting principles.

     (b) The Lessee agrees to defend, indemnify, pay and hold harmless the
Lessor, the Agent and each Lender, and the officers, directors, partners,
employees, agents and affiliates of the Lessor, the Agent and each Lender,
(collectively called the "Indemnitees") from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, expenses and disbursements of any kind or nature whatsoever
(including, without limitation, the reasonable fees and disbursements of counsel
for such Indemnitees in connection with any investigative, administrative or
judicial proceeding, commenced or threatened by any Person, whether or not any
such Indemnitee shall be designated as a party or a potential party thereto),
whether direct, indirect or consequential and whether based on any federal,
state or foreign laws, statutes, rules or regulations (including, without
limitation, securities and commercial laws, statutes, rules or regulations and
Environmental Laws), on common law or equitable or other cause or on contract or
otherwise, that may be imposed on, incurred by, or asserted against any such
Indemnitee, in any manner relating to or arising out of this Lease or the other
Transaction Documents or the transactions contemplated hereby or thereby
(including, without limitation, the Lenders' agreement to make the Loans to the
Lessor or the use or intended use of the proceeds of any of the Loans)
(collectively called the "Indemnified Liabilities"); provided, that the Lessee
shall not have any obligation to any Indemnitee hereunder with respect to any
Indemnified Liabilities to the extent that such Indemnified Liabilities arise
solely from the gross negligence or willful misconduct of that Indemnitee as
determined by a final judgment of a court of competent jurisdiction. To the
extent that the undertaking to defend, indemnify, pay and hold harmless set
forth in the preceding sentence may be unenforceable because it is violative of
any law or public policy, the Lessee shall contribute the maximum portion that
it is permitted to pay and satisfy under applicable law to the payment and
satisfaction of all Indemnified Liabilities incurred by the Indemnitees or any
of them.

     SECTION 13. Event of Loss. (a) If an Event of Loss shall occur with respect
to any Engine, the Lessee will promptly notify the Lessor and the Agent thereof
in writing (in any event within five (5) days of such occurrence) and will, not
later than 180 days after the occurrence of such Event of Loss, convey or cause
to be conveyed to the Lessor, free of all Liens (other than Permitted
Encumbrances) title to an Acceptable Alternate Engine. Prior to or at the time
of any such conveyance, the Lessee, at its own expense, will, as conditions to
such transfer, (i) furnish the Lessor with a warranty (as to title) bill of
sale, from a person and in form and substance reasonably satisfactory to the
Lessor, with respect to such Acceptable Alternate Engine, (ii) cause a Lease
Supplement to be filed for recording pursuant


<PAGE>
                                      -70-


to Title 49 of the United States Code, as amended, (iii) furnish the Lessor with
such evidence of the Lessee's title to such Acceptable Alternate Engine and of
compliance with the insurance provisions of Section 14 hereof with respect to
such Acceptable Alternate Engine as the Lessor may reasonably request, (iv)
furnish the Lessor with an opinion of the Lessee's counsel to the effect that
title to such Acceptable Alternate Engine has been duly conveyed to the Lessor
free and clear of all Liens except Permitted Encumbrances and the Lessor and the
Agent continue to have 1110 protection with respect to such Engine. Upon
satisfaction of the foregoing conditions, the Lessor shall transfer to or at the
direction of the Lessee without recourse or warranty all of the Lessor's right,
title and interest, if any, in and to (A) the Engine with respect to which such
Event of Loss occurred and furnish to or at the direction of the Lessee, at the
Lessee's expense, a bill of sale without warranty other than to the absence of a
Lessor Lien in form and substance reasonably satisfactory to the Lessee,
evidencing such transfer and (B) all claims, if any, against third parties, for
damage to or loss of the Engine subject to such Event of Loss, and such Engine
shall thereupon cease to be a Engine leased hereunder. The Lessee shall
cooperate with the Lessor and take all such actions as shall be requested by the
Lessor so that the Lessor complies with Section 4(f) of the Aircraft Chattel
Mortgage. For all purposes hereof, each such Acceptable Alternate Engine shall,
after such conveyance, be deemed part of the property leased hereunder, and
shall be deemed an "Engine." No Event of Loss under the circumstance
contemplated by the terms of this paragraph (a) shall result in any reduction in
Basic Rent or any other obligation of the Lessee hereunder.

     (b) With respect to any Engine, as between the Lessor and the Lessee, any
payments on account of an Event of Loss (other than insurance proceeds or other
payments the application of which is provided for in Section 14 below) received
from any governmental authority or other person shall be applied as follows:

          (A) if such payments are received with respect to an Event of Loss to
     any Engine that has been or is being replaced by the Lessee pursuant to the
     terms hereof, so long as there shall exist no Default or Lease Event of
     Default, such payment shall be paid over to or retained by the Lessee upon
     satisfaction of the conditions for replacement contained in paragraph (a)
     above and until such time shall be held by the Lessor as security for the
     obligations of the Lessee under the Lease; and

          (B) if such payments are received with respect to an Event of Loss
     with respect to which no replacement is being effected, so much of such
     payments as shall not exceed (A) the Stipulated Loss Value as of the date
     of payment plus (B) all unpaid Supplemental Rent due through the date of
     payment, plus (C) all unpaid Basic Rent for the period ending on the date
     of payment shall be paid by the Lessee to the Lessor and following the
     foregoing application, the balance, if any, of such payments shall be
     distributed between the Lessee and the Lessor as their respective interests
     may appear;


<PAGE>
                                      -71-


     (c) In the event of a requisition for use by the United States Government
of any Engine, the Lessee shall promptly notify the Lessor and the Agent of such
requisition and all of the Lessee's obligations under the Lease shall continue
to the same extent as if such requisition had not occurred. Any payments
received by the Lessor or the Lessee from the United States Government for the
use of such Engine, to the extent allocable to the Term, shall be paid over to,
or retained by, the Lessee.

     (d) Any amount referred to in this Section 13 that is payable to or
retained by the Lessee shall not be paid to the Lessee or retained by the
Lessee, if at the time of such payment or retention any Default or Lease Event
of Default shall have occurred and be continuing, but shall be held by or paid
over to the Lessor as security for the obligations of the Lessee under the Lease
and shall be applied against the Lessee's obligations hereunder as and when due.
At such time as there shall not be continuing any such Default or Lease Event of
Default, such amount shall be paid to the Lessee to the extent not previously
applied in accordance with the preceding sentence.

     SECTION 14. Insurance. (a) The Lessee will at all times carry and maintain
on or with respect to each of the Engines, at its own cost and expense, public
liability (including, without limitation, contractual liability, cargo
liability, passenger legal liability, bodily injury and product liability, but
excluding manufacturer's product liability) and property damage insurance with
insurers of recognized responsibility and reputation in amounts, of the type and
covering the risks customarily carried with respect to similar engines by
corporations engaged in the same or similar business and similarly situated with
the Lessee but in no event in an amount less than $500,000,000 per occurrence
(which shall include war risk, governmental confiscation and expropriation and
allied perils coverage). During any period when any of the Engines are on the
ground and not in operation, the Lessee may in respect of any such Engines carry
or cause to be carried, in lieu of insurance required by this Section, insurance
otherwise conforming with the provisions of this Section except that the amounts
of coverage shall not be required to exceed the amounts of comprehensive airline
liability insurance, and the scope of risk covered and type of insurance shall
be the same, as are customarily carried with respect to similar Engines on the
ground by corporations engaged in the same or similar business and similarly
situated with the Lessee. Any policies of insurance carried in accordance with
this Section 14 and any policies taken out in substitution or replacement of any
such policies (A) shall be amended to name the Agent, the Lenders and the Lessor
and their respective shareholders, directors, officers, members, partners,
servants, employees and agents as additional named insureds, (B) shall be
primary without right of contribution from any other insurance that is carried
by the Lessee, (C) shall expressly provide that all provisions thereof, except
the limits of the liability, shall operate in the same manner as if there were a
separate policy covering each insured, and (D) shall provide that the insurer
shall waive any right of subrogation against the Agent, the Lenders and the
Lessor.


<PAGE>
                                      -72-


     (b) The Lessee will at all times carry and maintain with insurers of
recognized responsibility and reputation on or with respect to the Engines, at
its own cost and expense, aircraft ground and flight all-risk hull insurance as
well as fire and extended coverage insurance on the Engines and other equipment
while removed from any airframe, which shall include war risk, governmental
confiscation and expropriation (other than by the United States Government) and
allied perils (if and to the extent that the same shall be maintained by the
Lessee with respect to similar engines owned or operated by the Lessee on the
same routes or if the Engines or other engines are operated on routes where the
custom is for Domestic Air Carriers similarly situated with the Lessee flying
comparable routes with similar engines to carry such insurance, of the type
usually carried by corporations engaged in the same or similar business and
similarly situated with the Lessee) including (A) strikes, riots, civil
commotions or labor disturbances, (B) any malicious act or act of sabotage and
(C) hijacking (air piracy) or any unlawful seizure or wrongful exercise of
control of the Engine or crew of the aircraft in which such Engine is installed
in flight (including any attempt at such seizure or control) made by any person
or persons aboard such aircraft or another aircraft acting without the consent
of the insured; provided, that such insurance (including any self-insurance to
the extent permitted below) shall at all times be for an agreed value not less
than the greater of the Stipulated Loss Value as of the closest Stipulated Loss
Determinate Date and $50,000,000. During any period when any Engine is on the
ground and not in operation, the Lessee may in respect of any such Engines carry
or cause to be carried, in lieu of the insurance required by this Section,
insurance otherwise conforming hereto except that the scope of risk covered and
type of insurance shall be the same as are from time to time customarily carried
with respect to similar engines by corporations engaged in the same or similar
business and similarly situated with the Lessee for engines on the ground in an
amount at least equal to the applicable amount provided above. All such
insurance shall name the Agent, the Lenders and the Lessor as additional
insureds and loss payees to the extent that their interest may appear and shall
provide that any loss to any Engine in excess of $2,000,000 (and, if a Default
or Lease Event of Default has occurred and is continuing, any such loss) shall
be payable to the Lessor and to the Agent for the benefit of the Lenders; and
shall be primary without right of contribution from any other insurance that is
carried by the Lessor or the Agent with respect to its interest therein. In the
event that the Lessee arranges separate insurances to cover the all-risk hull
insurance and the war and perils hull insurance, the Lessee shall ensure that
the insurers subscribing to such insurances shall agree to a 50/50 claims
funding arrangement in the event of any dispute as to which insurance is
applicable.

     The Lessee may self-insure, by way of deductible or equivalent provisions
in insurance policies, the risks required to be insured against pursuant to this
Section 14(b) in such reasonable amounts as are then applicable to other similar
engines in the Lessee's fleet that are of a value comparable to the Engines, and
as are not substantially greater than amounts self-insured by corporations
engaged in the same or similar business and similarly


<PAGE>
                                      -73-


situated with the Lessee; provided, however, that the Lessee may not self-insure
in an amount in excess of $1,000,000 without the prior written consent of the
Lessor and the Agent.

     (c) Any policies of insurance required pursuant to either paragraph (a) or
paragraph (b) above shall: (A) be amended to name the Lessor, the Agent and the
Lenders as additional named insureds, but without the Lessor, the Agent or the
Lenders being thereby liable for premiums (and the insurance companies waiving
their right with respect thereto), (B) provide that in respect of the interest
of (x) the Lessor or (y) the Agent or the Lenders in such policies the insurance
shall not be invalidated by any action or inaction of (x) the Lessee or (y) the
Lessee or the Lessor, respectively, and shall insure the interests of the Agent
and the Lenders regardless of any breach or violation by the Lessee, the Lessor
or any Person (other than the Agent) of any warranty, declaration, condition or
exclusion from coverage contained in such policies, (C) provide that if such
insurance is cancelled, or if any material change is made in the coverage that
affects the interest of the Lessor, the Agent or any Lender, or if such
insurance is allowed to lapse for nonpayment of premium, such cancellation,
change or lapse shall not be effective as to the Lessor, the Agent or any Lender
for thirty (30) days (seven (7) days, or such shorter or longer period as may
from time to time be customarily available in the industry, in the case of any
war risk and allied perils coverage) after receipt by the Agent and the Lessor
of written notice from such insurers of such cancellation, change or lapse, (D)
be in full force and effect throughout any geographical areas at any time
traversed by any Engine and shall be payable in U.S. dollars, (E) waive any
right of the insurers to any setoff or counterclaim or any other deduction,
whether by attachment or otherwise in respect of any liability of the Lessee,
the Lessor or the Agent except in respect of outstanding premium due for the
Engines, (F) waive all rights of subrogation against the Lessor and the Agent
and (G) include a year 2000 date recognition writeback.

     (d) In the case of a lease or contract with the United States or any agency
or instrumentality thereof in respect of any Engine, a valid agreement by the
United States or such agency or instrumentality to indemnify the Lessee against
the same risks against which the Lessee is required hereunder to insure shall be
considered adequate insurance with respect to such Engine to the extent of the
risks and in the amounts that are the subject of any such agreement to
indemnify.

     (e) On or prior to the date hereof, and annually thereafter on or prior to
January 31, the Lessee will furnish to the Lessor and the Agent (A) a report
signed by a firm of independent aircraft insurance brokers, appointed by the
Lessee and not objected to by the Lessor or the Agent, describing in reasonable
detail acceptable to the Lessor and the Agent the insurance then carried and
maintained on or with respect to the Engines and stating that in the opinion of
such firm such insurance complies with the terms of this Section 14 and is
adequate to protect the interests of the Lessee, the Lessor and the Agent, and
(B) certificates of the insurer or insurers evidencing the insurance covered by
the report. The Lessee will cause


<PAGE>
                                      -74-


such brokers to advise the Agent in writing (x) promptly of any default in the
payment of any premium and of any other act or omission on the part of the
Lessee of which such firm has knowledge and that might invalidate or render
unenforceable, in whole or in part, any insurance on any Engine and (y) at least
thirty (30) days prior to the expiration or termination date, or date of
effectiveness of any material change, of any insurance carried and maintained on
the Engines hereunder.

     (f) All insurance payments and other payments received by the Agent, the
Lessor or the Lessee from insurance referred to in paragraph (b) above shall be,
if received by the Lessor or the Lessee, immediately paid to the Agent, as agent
for itself and the Lessor and shall be paid to the Lessee upon compliance by the
Lessee with the terms of Section 13, provided that no Default or Lease Event of
Default shall have occurred and be continuing.

     (g) The Lessee shall not create or permit to exist any Lien over the
insurances required by this Lease, or its interest therein, save as constituted
by this Lease and the Credit Agreement.

     (h) If at any time the Lessee fails to maintain in full force and effect
insurances in compliance with any provision of this Article 14, the Lessor shall
be entitled but not bound (without prejudice to any other rights that it may
have or acquire under this Lease by reason of such failure) (i) to pay any
premiums due or to effect or maintain insurances satisfactory to the Lessor or
otherwise remedy such failure in such manner as the Lessor considers
appropriate, and the Lessee shall immediately reimburse the Lessor in full for
any amount so expended by the Lessor and/or (ii) at any time while such failure
is continuing, to require any Engine to remain at any airport, or to proceed to
and remain at any airport designated by the Lessor, the Agent or the Lenders,
until such failure is remedied.

     (i) Nothing in this Section 14 shall prohibit the Agent, or any Lender or
the Lessor from obtaining insurance with respect to any Engine for its own
account. The Lessee may, at its own expense, carry insurance with respect to its
interest in any Engine in amounts in excess of that required to be maintained by
this Section 14. No insurance maintained by the Agent, the Lessor or any Lender
shall prevent the Lessee from carrying the insurance required or permitted by
this Section. Proceeds of any such insurance carried by the Lessee, the Agent or
any Lender shall be paid as provided in the insurance policy relating thereto
and no such Person shall have any duty to obtain any such insurance.

     SECTION 15. Assignment. Except as permitted in accordance with Section 10,
the Lessee will not, without the prior written consent of the Lessor, assign any
of its rights hereunder or in any of the Engines. The Lessor agrees that it will
not assign or convey its right, title or interest in or to this Lease or any of
the Engines except in accordance with the Credit Agreement. Subject to the
foregoing, the terms and provisions of this Lease shall be


<PAGE>
                                      -75-


binding upon and inure to the benefit of the Lessor and the Lessee and their
respective successors and permitted assigns and shall inure to the direct
benefit of, and shall also be enforceable by, the Agent and the Lenders, and
their respective successors, as assignees of the Lessor.

     SECTION 16. Events of Default. Each of the following events shall
constitute a Lease Event of Default (whether any such event shall be voluntary
or involuntary or come about or be effected by operation of law or pursuant to
or in compliance with any judgment, decree or order of any court or any order,
rule or regulation of any administrative or governmental body) and each such
Lease Event of Default shall continue so long as, but only as long as, it shall
not have been remedied:

          (a) the Lessee shall fail to pay any installment of Rent, Stipulated
     Loss Value or any other amounts owing pursuant to this Lease within 5 days
     after the due date thereof;

          (b) the Lessee shall fail (i) to comply in any material respect with
     the maintenance standards or (ii) to procure insurance coverage as
     prescribed herein or (iii) to operate any Engine at a time or in a place
     where insurance described in Article 14 shall not be in effect;

          (c) there shall exist a Lease Event of Default under, and as defined
     in, any other Lease or the Lessee shall fail to perform or observe any
     other covenant or condition set forth in this Lease or any other
     Transaction Document, which failure shall remain unremedied for a period of
     10 Business Days after written notice from the Lessor or the Agent, unless
     action has been taken within 15 Business Days to remedy such breach and
     such action is being diligently pursued, provided such breach is capable of
     being remedied;

          (d) any representation or warranty of the Lessee in any Transaction
     Document or in any certificate furnished pursuant to any Transaction
     Document is found to be incorrect in any material respect at the time it
     was made and such breach shall remain unremedied for a period of 15
     Business Days after written notice thereof;

          (e) (i) a court having jurisdiction in the premises shall enter a
     decree or order for relief in respect of the Lessee or any of its
     Subsidiaries in an involuntary case under the Bankruptcy Code or under any
     other applicable bankruptcy, insolvency or similar law now or hereafter in
     effect, which decree or order is not stayed; or any other similar relief
     shall be granted under any applicable federal or state law, or (ii) an
     involuntary case shall be commenced against the Lessee or any of its
     Subsidiaries under the Bankruptcy Code or under any other applicable
     bankruptcy, insolvency or similar law now or hereafter in effect; or a
     decree or order of a court having jurisdiction in the


<PAGE>
                                      -76-


     premises for the appointment of a receiver, liquidator, sequestrator,
     trustee, custodian or other officer having similar powers over the Lessee
     or any of its Subsidiaries, or over all or a substantial part of its
     property, shall have been entered; or there shall have occurred the
     appointment of an interim receiver, trustee or other custodian of the
     Lessee or any of its Subsidiaries; or a warrant of attachment, execution or
     similar process shall have been issued against any substantial part of the
     property of the Lessee or any of its subsidiaries, and any such event
     described in this clause (ii) shall continue for 60 days unless dismissed,
     bonded or discharged;

          (f) (i) the Lessee or any of its Subsidiaries shall have an order for
     relief entered with respect to it or commence a voluntary case under the
     Bankruptcy Code or under any other applicable bankruptcy, insolvency or
     similar law now or hereafter in effect, or shall consent to the entry of an
     order for relief in an involuntary case, or to the conversion of an

     such Indebtedness or Contingent Obligation(s), if the effect of such breach
     or default is to cause, or to permit the holder or holders of that
     Indebtedness or Contingent Obligation(s) (or a trustee on behalf of such
     holder or holders) to cause, that Indebtedness or Contingent Obligation(s)
     to become or be declared due and payable prior to its stated maturity or
     the stated maturity of any underlying obligations, as the case may be (upon
     the giving or receiving of notice, lapse of time, both, or otherwise);

          (m) any money judgment, writ or warrant of attachment or similar
     process involving (i) in any individual case an amount in excess of $5

     the combined voting power of all Securities of the Lessee entitled to vote
     in the election of directors, other than Securities having such power only
     by reason of the happening of a contingency, or (b) any Person or any two
     or more Persons acting in concert (in any such case, excluding Permitted

                                      -78-


     (c) the Board of Directors of the Lessee shall not consist of a majority of
     Continuing Directors or (ii) a "Change of Control" shall occur under any of
     the Pass Through Trust Documents, any of the Senior Note Documents or any
     other Material Agreement (as in effect on the date of such occurrence);
     provided, however, that, following the consummation of the Holding Company
     Reorganization, references in clause (i) above to the Lessee shall be
     deemed to be references to the Holding Company, and, after the consummation
     of the Holding Company Reorganization, it shall also be a Lease Event of
     Default if, at any time, the Holding Company ceases to own directly or
     indirectly 100% of the outstanding Securities of the Lessee; provided
     further, however, that a "Lease Event of Default" under clause (ii) above
     arising as a result of the Holding Company Reorganization shall not
     constitute a "Lease Event of Default;" provided further, however, that, in
     the event that Permitted Holders cease to own 30% of the combined voting
     power of all Securities of the Lessee (or the Holding Company, as the case
     may be) because of the issuance of Securities of the Lessee, or the Holding
     Company, as the case may be, (as opposed to the Permitted Holders selling
     Securities), then the failure to maintain the 30% ownership level shall not
     constitute a Lease Event of Default unless the Permitted Holders shall
     cease to own shares of capital stock constituting 25% of the combined
     voting power of all Securities of the Lessee (or the Holding Company, as
     the case may be);

          (o) if any consent, authorization, license or approval of, or
     registration with or declaration to any governmental entity required by the
     Lessee to authorize, or required by the Lessee in connection with, the
     execution, delivery, validity, enforceability or admissibility in evidence
     of this Lease or any other Transaction Document or the performance by the
     Lessee of its obligations hereunder or thereunder is modified in a manner
     unacceptable to the Lessor or is withheld, or is revoked, suspended,
     canceled, withdrawn or terminated or expires and is not renewed, or
     otherwise ceases to be in full force and effect and the Lessor reasonably
     determines that such modification, withholding revocation, suspension,
     cancellation, withdrawal, termination or non-renewal or cessation may
     significantly prejudice its rights under or in connection with this Lease,
     may have a material adverse effect on the Lessee's ability to perform its
     obligations hereunder or jeopardize the respective interests of the Lessor
     or any Lender in any of the Engines or may give rise to criminal liability
     of or the Lessor;

          (p) if any event occurs, circumstance arises or proceeding is taken
     with respect to the Lessee in any jurisdiction to which the Lessee is
     subject that has an effect equivalent or similar to any of the events
     mentioned in Sections 16(e) or (f);

          (q) if the Lessee suspends or ceases or threatens to suspend or cease
     to carry on its business;


<PAGE>
                                      -79-


          (r) if the Lessee disposes, threatens to dispose or takes any action
     to dispose of all or a material part of its assets, whether by one or a
     series of transactions, related or not, and such disposal or action will
     have a material adverse effect on its ability to perform its obligations
     under this Lease or any other Transaction Document;

          (s) if the existence, validity, enforceability or priority of the
     rights of the Lessor in respect of any of the Engines hereunder, or the
     rights of any Lender, as mortgagee, of any of the Engines or the Lender as
     assignee of the insurances are challenged by the Lessee or any other person
     claiming through the Lessee;

          (t) if the Lessee sells or executes any bill of sale affecting any of
     the Engines or any interest therein or agrees or purposes to do any of the
     same, or contests in any legal proceedings the Lessor's ownership of any of
     the Engines;

          (u) if any governmental authority shall have condemned, seized or
     appropriated all or substantially all of the property of the Lessee; or

          (v) if the Lessee becomes obligated to make any "change of control"
     put payments in connection with the Holding Company Reorganization that,
     when aggregated with all payments made under Section 7(e)(6), exceed
     $75,000,000 or if, after giving effect to such "change of control" put
     payments, (A) the Lessee shall have less than $150,000,000 in Cash or Cash
     Equivalents on its balance sheet or (B) its Consolidated Leverage Ratio
     (calculated on a pro forma basis as if the proposed payment had been
     consummated on the last day of the most recent four fiscal quarter period)
     shall exceed the lower of 4.25:1.00 or the ratio to be met in accordance
     with Section 7(f)(ii) for the immediately succeeding fiscal quarter end.

     SECTION 17. Remedies. Upon the occurrence of any Lease Event of Default and
at any time thereafter so long as the same shall be continuing, the Lessor may,
at its option, declare, by written notice to the Lessee, this Lease to be in
default, except that upon the occurrence of a Lease Event of Default referred to
in clauses (e), (f) or (g) of Section 16, this Lease shall be deemed declared in
default without any further act or notice, and at any time thereafter, the
Lessor may do one or more of the following with respect to all or any part of
any or all of the Engines as the Lessor in its sole discretion shall elect:

          (a) upon the written demand of the Lessor and at the Lessee's expense,
     promptly return any Engine as the Lessor may so demand to the Lessor or its
     order in the manner and condition required by, and otherwise in accordance
     with all the provisions of, Section 8 hereof as if such Engine were being
     returned at the end of the Term, or the Lessor, at its option, may enter
     upon the premises where all or any part of any Engine is located and take
     immediate possession of and remove the same by


<PAGE>
                                      -80-


     summary proceedings or otherwise, all without liability accruing to the
     Lessor for or by reason of such entry or taking of possession or removal,
     whether for the restoration of damage to property caused by such action or
     otherwise; provided, that if the Lessee shall for any reason fail to
     execute and deliver instruments deemed necessary or advisable by the Lessor
     to obtain possession of any of the Engines, the Lessor shall be entitled,
     in a proceeding (which proceeding may be done on an ex parte basis without
     notice to the Lessee), to a preliminary injunction granting the Lessor the
     right to possess the Engines without having to post a bond or provide any
     other type of security and to a final judgment for specific performance,
     conferring the right to immediate possession upon the Lessor and requiring
     the Lessee to execute and deliver such instruments to the Lessor;

          (b) sell any Engine at public or private sale, as the Lessor may
     determine, or otherwise dispose of, hold, use, operate, lease to others or
     keep idle any Engine as the Lessor, in its sole discretion, may determine,
     all free and clear of any rights of the Lessee, except as hereinafter set
     forth in this Section 17, and without any duty to account to the Lessee
     with respect to such action or inaction;

          (c) whether or not the Lessor shall have exercised, or shall
     thereafter at any time exercise, any of its rights under paragraph (a) or
     (b) above with respect to the Engine, the Lessor, by written notice to the
     Lessee specifying a payment date, may demand that the Lessee pay to the
     Lessor, and the Lessee shall pay the Lessor, on the payment date so
     specified, any Basic Rent due on or before the payment date so specified
     plus, as liquidated damages for loss of a bargain and not as a penalty (in
     lieu of the installments of Basic Rent for the Engines due after the date
     specified in such notice if any), an amount equal to the Stipulated Loss
     Value for the Engines computed as of the immediately preceding Stipulated
     Loss Determination Date, together with interest, if any, at the Past Due
     Rate on the amount of such Basic Rent and Stipulated Loss Value from the
     Stipulated Loss Determination Date as of which Stipulated Loss Value is
     computed until the date of actual payment; and upon such payment of
     liquidated damages and all Supplemental Rent then due and payable by the
     Lessee hereunder, the Lessor shall transfer (without any representation,
     recourse or warranty whatsoever) the Engines to the Lessee and the Lessor
     shall execute and deliver such documents evidencing such transfer and take
     such further action as the Lessee shall reasonably request to effect such
     transfer;

          (d) in the event that the Lessor, pursuant to paragraph (b) above,
     shall have sold any of the Engines, the Lessor, in lieu of exercising its
     rights under paragraph (c) above with respect to the Engines, may, if it
     shall so elect, demand that the Lessee pay the Lessor, and the Lessee shall
     pay to the Lessor, on the date of such sale, any accrued rent with respect
     to the Engines due on or prior to such date plus, as liquidated


<PAGE>
                                      -81-


     damages for loss of a bargain and not as a penalty, the amount of any
     deficiency between the net proceeds of such sale (after deduction of all
     reasonable costs of sale) and the Stipulated Loss Value of such the
     Engines, computed as of the date of such sale together with interest, if
     any, on the amount of such deficiency, at the Past Due Rate, from the date
     of such sale to the date of actual payment of such amount;

          (e) the Lessor may terminate or cancel this Lease or proceed by
     appropriate court action to enforce the terms hereof or to recover damages
     for breach hereof; and

          (f) the Lessor may exercise any other right or remedy which may be
     available to it under applicable law.

     In addition, the Lessee shall be liable, except as otherwise provided
above, without duplication of amounts payable hereunder, for any and all unpaid
Rent due hereunder before, after or during the exercise of any of the foregoing
remedies and for all reasonable legal fees and other costs and expenses incurred
by the Lessor and the Agent and any Lender (including reasonable allocated time
charges of internal counsel for the Lender) in connection with the Lease Event
of Default, the exercise of remedies and the return of any Engine in accordance
with the terms of Section 8 hereof or in placing such Engine (which for purposes
hereof, shall include, without limitation, all logs, manuals and data and
inspection, maintenance, modification and overhaul and similar records with
respect thereto) in the condition and airworthiness required by such Section.
The Lessee hereby acknowledges that it shall be directly liable for such costs
and expenses to any Person designated by the Lessor, the Agent or any Lender (as
the case may be) to provide services in connection with or to effect the return
of any Engine in accordance with the terms of Section 8 hereof or in placing
such Engine (which for purposes hereof shall include, without limitation, such
logs, manuals and records) in the condition and airworthiness required by such
Section.

     At any sale of any Engine or any part thereof pursuant to this Section 17,
the Lessor or the Agent or any Lender may bid for and purchase such property.
The Lessor agrees to give the Lessee at least 10 days' written notice of the
date fixed for any public sale of any Engine or of the date on or after which
will occur the execution of any contract providing for any private sale. Except
as otherwise expressly provided above, no remedy referred to in this Section 17
is intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to above or otherwise available to the Lessor at law or in
equity or otherwise; and the exercise or beginning of exercise by the Lessor of
any one or more of such remedies shall not preclude the simultaneous or later
exercise by the Lessor of any or all of such other remedies. No waiver by the
Lessor of any Lease Event of Default shall in any way be, or be construed to be,
a waiver of any future or subsequent Lease Event of Default. To the extent
permitted by applicable law, the Lessee hereby waives any rights now or
hereafter conferred by statute or otherwise that may require the Lessor to sell,
lease, or otherwise use any


<PAGE>
                                      -82-


Engine or any part thereof in mitigation of the Lessor's damages as set forth in
this Section 17 or that may otherwise limit or modify any of the Lessor's rights
and remedies in this Section 17.

     Notwithstanding any of the foregoing provisions of this Section 17, so long
as any Loan relating to any Engine or other Obligations (other than principal
and interest on Loans relating to aircraft or other spare engines) are
outstanding under the Credit Agreement, all rights of the Lessor under this
Section 17 shall be exercised only by the Agent as assignee of the Lessor's
rights under this Lease pursuant to the Aircraft Chattel Mortgage.

     SECTION 18. Lessee's Cooperation Concerning Certain Matters. (a) Forthwith
upon the execution and delivery of each Lease Supplement from time to time
required by the terms hereof and upon the execution and delivery of any
amendment to this Lease, the Lessee (at its expense), unless such supplement or
amendment relates solely to the assignment of all or any portion of the Lessor's
interest hereunder, will cause such Lease Supplement (and, in the case of the
initial Lease Supplement, this Lease as well) or amendment to be duly filed and
recorded, and maintained of record, in accordance with the applicable laws of
the government of registry of the Engines. In addition, the Lessee at its
expense will promptly and duly execute and deliver to the Lessor and the Agent
such further documents and take such further action as the Lessor and the Agent
may from time to time reasonably request in order more effectively to carry out
the intent and purpose of this Lease and the other Transaction Documents and to
establish and protect the rights and remedies created or intended to be created
in favor of the Lessor and the Agent hereunder and under the other Transaction
Documents, including, without limitation, if requested by the Lessor and the
Agent, the execution and delivery of supplements or amendments hereto, at the
expense of the Lessee, each in recordable form, and all financing statements and
continuation statements, and all similar notices required by applicable law at
all times to be kept recorded and filed in such manner and such places as the
Lessor and the Agent may reasonably request.

     (b) The Lessee agrees at its own expense to furnish to the Lessor and the
Agent promptly after execution and delivery of any supplement and amendment
hereto, an opinion of counsel satisfactory to the Lessor and the Agent (which
may include the Lessee's general counsel) stating that, in the opinion of such
counsel, such supplement or amendment to the Lease (or a financing statement,
continuation statement or similar notice thereof if and to the extent permitted
or required by applicable law) has been properly recorded or filed for record in
all public offices in which such recording or filing is necessary to protect the
right, title and interest of the Lessor hereunder and the Agent under the Loan
Documents.

     SECTION 19. Notices. All notices required under the terms and provisions
hereof shall be in writing (including telex, facsimile or similar writing) and
shall be effective (a) if given by facsimile device, when transmitted and the
appropriate confirmation received,

<PAGE>
                                      -83-


(b) if given by certified mail, three Business Days after being deposited in the
United States mail, with appropriate postage prepaid, (c) if given by telex,
upon receipt by the party transmitting the telex of such party's answerback code
at the end of such telex (receipt of confirmation in writing not being necessary
to the effectiveness of any telex) and (d) if given by overnight service or
other means, when received or personally delivered, addressed:

          (i) if to the Lessee, at 538 Commons Drive, Golden, Colorado 80401,
     Attention: Counsel, or to such other address as the Lessee shall from time
     to time designate in writing to the Lessor; and

          (ii) if to the Lessor, at 538 Commons Drive, Golden, Colorado 80401,
     Attention: Mr. Richard H. Shuyler, or to such other address as the Lessor
     shall from time to time designate in writing to the Lessee, with a copy to
     the Agent at 130 Liberty Street, New York, New York 10006, Attention:
     Marguerite Sutton.

     SECTION 20. Net Lease, True Lease, etc. (a) The Lessee's obligations to pay
Rent and all other amounts payable hereunder shall be absolute and unconditional
and shall not be affected by any circumstance whatsoever, including, without
limitation, (i) any setoff, counterclaim, recoupment, defense or other right
that the Lessee may have against the Lessor, the Agent, the Lenders, any
manufacturer, any supplier or any other Person for any reason whatsoever, (ii)
any defect in the title, airworthiness, eligibility for registration under Title
49 of the United States Code, as amended, or other applicable law, condition,
design, compliance with specifications, operation or fitness for use of, or any
damage to or loss or destruction of, the Engines, or any theft, interference,
interruption or cessation in or prohibition of the use or possession thereof by
the Lessee or any sublessee for any reason whatsoever, including, without
limitation, any such interference, interruption, cessation or prohibition
resulting from the act of any governmental authority or any other Person, (iii)
any Liens, encumbrances or rights of any other Person with respect to the
Engines, (iv) the invalidity or unenforceability or lack of due authorization or
other infirmity of this Lease or any other Transaction Document or document or
instrument executed pursuant hereto or thereto, or any lack of right, power or
authority of the Lessor or the Lessee or any other party to any other
Transaction Document to enter into this Lease or any other Transaction Document
or any such document or instrument, (v) any loss of or damage to any Engine or
any Part, (vi) any insolvency, bankruptcy, reorganization or similar proceedings
by or against the Lessee or any other Person, or (vii) any failure, breach or
delay by the Lessor or any other Person in performing or complying with any term
of this Lease or any other cause whether similar or dissimilar to the foregoing,
any present or future law notwithstanding, it being the intention of the parties
that all Rent payable by the Lessee hereunder shall continue to be payable in
all events in the manner and at the times provided herein. Such Rent shall not
be subject to any abatement and the payments thereof shall not be subject to any
setoff or any reduction for any reason whatsoever, including any present or
future claims of the Lessee against the Lessor or any other


<PAGE>
                                      -84-


Person under this Lease or otherwise. The Lessee hereby waives, and hereby
agrees to waive at any future time at the request of the Lessor, to the full
extent now or then permitted by applicable law, any and all rights that it may
now have or that at any time hereafter may be conferred upon it, by statute or
otherwise, to terminate, cancel, quit or surrender this Lease except in
accordance with the express terms hereof. Each payment of Rent made by the
Lessee to the Lessor shall be final as to the Lessor and the Lessee. The Lessee
will not seek to recover all or any part of any such payment of Rent from the
Lessor for any reason whatsoever.

     (b) It is the intention of the parties that the Lessor and the Agent, as
assignee of the Lessor's right under this Lease pursuant to the Aircraft Chattel
Mortgage, shall be entitled to the benefits of 11 U.S.C. ss. 1110 or any
analogous section of the Federal bankruptcy laws, as amended from time to time
with respect to the right to repossess the Engines and Parts as provided herein,
and in any circumstances where more than one construction of the terms and
conditions of this Lease is possible, a construction that would preserve such
benefits shall control over any construction that would not preserve such
benefits or would render them doubtful. To the extent consistent with the
provisions of 11 U.S.C. ss. 1110 or any analogous section of the federal
bankruptcy laws, as amended from time to time, it is hereby expressly agreed,
that notwithstanding any other provisions of the federal bankruptcy law, as
amended from time to time, any right of the Lessor and the Agent, as assignee of
the Lessor under the Aircraft Chattel Mortgage, to take possession of the
Engines in compliance with the provisions of this Lease shall not be affected by
the provisions of 11 U.S.C. ss. 362 or ss. 363, as amended from time to time, or
any analogous provisions of any superseding statute or any power of the
bankruptcy court to enjoin such taking of possession.

     (c) The Lessor and the Lessee hereby agree that this Lease, including any
modifications, supplements and amendments thereto, is intended to be treated as
a lease for purposes of the Internal Revenue Code, and neither the Lessor nor
the Lessee shall file any tax returns in a manner or take any other action or
position inconsistent with the foregoing or with the Lessor's ownership of the
Engines. Nothing contained in this Lease shall be construed as conveying to the
Lessee any right, title or interest in the Engines except as a Lessee only. The
Engines shall at all times during the term of this Lease be the sole and
exclusive property of the Lessor.

     SECTION 21. Purchase Option.

     (a) Purchase Option. So long as no Lease Event of Default has occurred and
is continuing, the Lessee shall have the option to purchase the Engines at the
end of the Term for a purchase price equal to the higher of the Fair Market
Sales Value (assuming that the Engines are in the condition required by the
Lease) as of such date and Stipulated Loss Value plus all accrued Rent and all
Supplemental Rent then due. Upon the payment by the Lessee of the full of such
amounts, the Lessor shall convey to the Lessee all right, title and


<PAGE>
                                      -85-


interest of the Lessor in and to the Engines on an "as-is, where is" basis,
without recourse or warranty.

     (b) Notice of Purchase. In order to exercise any purchase option under
Section 21, the Lessee shall be required to give not less than 90 days (but not
more than 360 days) irrevocable prior written notice to the Lessor. The Lessee
will give the Lessor prior written irrevocable notice not less than 90 days (but
not more than 360 days) before the expiration of the Term of its determination
to return the Engines and not exercise any purchase option under this Section
21. If the Lessee fails to give notice as required herein, the Lessee will be
deemed to have elected to return the Engines to the Lessor.

     SECTION 22. Lessor's Right to Perform for Lessee. If the Lessee fails to
make any payment of Rent required to be made by it hereunder or fails to perform
or comply with any of its agreements contained herein, then the Lessor may
itself make such payment or perform or comply with such agreement but shall not
be obligated hereunder to do so, and the amount of such payment and the amount
of the reasonable expenses of the Lessor incurred in connection with such
payment or the performance of or compliance with such agreement, as the case may

ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS LEASE OR ANY OTHER

obligations, the Lessor has agreed in the Aircraft Chattel Mortgage, among other
things, to assign to the Agent this Lease and the Lease Supplements and to
mortgage in favor of the Agent each of the Engines, subject to the reservations
and conditions therein set forth. All rights of the Lessor hereunder are subject
to the Aircraft Chattel Mortgage and the Lessor and the Lessee agree that so
long as the lien of the Aircraft Chattel Mortgage has not been discharged in
accordance with its terms, (i) all payments hereunder shall be made to the Agent
for the benefit of Lenders to the extent of the Lenders' interest in such
payments, (ii) all notices from or to the Lessor shall be copied to the Agent
and (iii) the Lessee shall not take any actions that the Lessor would be
prohibited from taking under the terms of the Aircraft Chattel Mortgage. The
Lessee hereby acknowledges due notice of, and consents to, such assignment and
to the creation of such mortgage and security interest. To the extent, if any,
that this Lease and any Lease Supplement constitutes chattel paper (as such term
is in effect in any applicable jurisdiction), no security interest in this Lease
or any Lease Supplement may be created through the transfer or possession of any
counterpart other than the original executed counterpart containing the receipt
therefor executed by the Agent on the signature page hereof or thereof.

Lenders and the Agent, pursuant to which the Lenders have agreed, on the terms
and conditions set forth in the Credit Agreement, to make term loans to the
Company in the principal amount of up to $300 million (the "Loans") to enable
the Company to refinance certain indebtedness currently encumbering the Spare
Engine Collateral (as defined below). The indebtedness with respect to the Loans
made by the Lenders is to be evidenced by certain promissory notes of the
Company to the order of the Lenders of even date herewith issued under and
pursuant to the Credit Agreement (such promissory notes, as they may be amended,
modified, supplemented, renewed, converted or extended from time to time, being

Lenders to make the Loans, the Company hereby agrees with the Agent as follows:

Bankruptcy Code), and to secure performance of all obligations and covenants of

Documents (all such payment and performance obligations of the Com-

     be excluded from any indemnification any Lessor Tax (as defined in the

     enforceability of this Mortgage or the perfection of the lien hereof or
     unless proceedings shall have been commenced to foreclose any lien which
     may have attached as security for such Tax, nothing in this Section shall
     require the payment of any Tax so long as and to extent that validity
     thereof shall be contested in good faith by appropriate legal proceedings

     however, that if following its issuance, the United States FAA
     airworthiness certificate of any Engine shall be withdrawn, then subject to
     the provisions of Section 4(f) hereof, so long as the Company is diligently
     taking or causing to be taken all necessary action to promptly correct the

     maintenance, inspection and maintenance control programs, and in the same
     manner and with the same care used by the Lessee with respect to the same
     or similar aircraft and engines owned or operated by the Lessee so as to
     keep the same in as good operating condition as when originally mortgaged
     hereunder, ordinary wear and tear excepted, which practices shall at all
     times be at or above the standard of the industry in the United States for
     prudent maintenance of similar equipment, and (D) in such manner as may be
     necessary to maintain in full force all warranties of the manufacturers
     thereof. The Company shall maintain, or shall cause Lessee to maintain, all
     records, logs and other materials which may be required to permit each
     Engine to be so utilized.

          The Company will comply in all material respects with all
     airworthiness directives, mandatory notes or modifications or similar
     requirements affecting the same (including those issued by the manufacturer
     or supplier) in such condition so as to comply with the provisions of this
     Mortgage and the rules and regulations of the FAA from time to time in
     force and applicable to the Engines. No Engine will be maintained, used or
     operated in violation of any law or any rule, regulation or order of any
     government or governmental authority having jurisdiction (domestic or
     foreign), or in violation of any airworthiness certificate, license or
     registration relating to such Engine issued by any such authority, and in
     the event that such laws, rules, regulations or orders require alteration
     of any Engine, the Company, at its own cost and expense, will conform
     thereto or obtain conformance therewith and will maintain the same in
     proper operating condition under such laws, rules, regulations and orders;
     provided, however, that the Company may, in good faith (after having
     delivered to the Agent an Officer's Certificate stating the facts with
     respect thereto), contest the validity or application of any such law,
     rule, regulation or order in any reasonable manner which does not, in the
     Agent's opinion, adversely affect the interests under this Mortgage of the
     Agent or any Lender.

          The Company will not operate, use or locate any Engine, (I) in any
     area in which any insurance required to be maintained pursuant to Section
     4(g) shall not be at the time in full force and effect, or in any area
     excluded from coverage by an insurance policy in effect with respect to any
     such Engine, except in the case of a requisition for use by the United
     States of America, and then only if Company obtains indemnity or "war risk"
     insurance in lieu of such insurance from the United States of America
     against the risks and in the amounts required by said Section covering such
     area, or (II) in any recognized or threatened area of hostilities unless
     fully covered to the Agent's satisfaction by war risk and political risk
     and allied perils insurance or unless any such Engine is operated or used
     under contract with the Government of the United States of America under
     which contract that Government provides "war risk" insurance or assumes
     liabilities for any damages, loss, destruction or failure to return
     possession of any such Engine at the end of the term of such contract and
     for injury to persons or damage to property of others.

          The Company shall not use any Engine nor suffer it to be used in any
     manner or for any purpose excepted from any of the insurance on or in
     respect of any such Engine or for the purpose of carriage of goods of any
     description excepted from such insurance nor do, or permit to be done,
     anything which, or admit to do anything the admission of which, may
     invalidate any of such insurance.

          (d) Possession. The Company will not, without the prior written
     consent of the Agent, sell, assign, lease or otherwise in any manner
     deliver, transfer or relinquish


<PAGE>
                                      -10-


     possession or control of, or transfer the right, title or interest of the
     Company in, any Engine except that the Company may enter into and perform
     all provisions and terms of the Lease and the Lessee or the Company, unless
     a Potential Event of Default or Event of Default shall have occurred and be
     continuing, without the prior written consent of the Agent, may take the
     following actions so long as the actions to be taken shall not deprive the
     Agent of the first priority Lien of this Mortgage on the assets subject
     hereto and so long as the actions to be taken shall not deprive the Company
     as Lessor of the protections of Section 1110 of the Bankruptcy Code with
     respect to any of the Engines nor shall such actions deprive the Agent of
     the protections of Section 1110 of the Bankruptcy Code with respect to any
     of the Engines as assignee of the Company's rights under this Mortgage:

               (i) transfer possession of any Engine other than by lease to the
          United States of America or any instrumentality thereof pursuant to
          the Civil Reserve Air Fleet Program (as administered pursuant to
          Executive Order 12656, or any substitute order) or any similar or
          substitute programs;

               (ii) transfer possession of any Engine to the manufacturer
          thereof for testing or other similar purposes or any other
          organization for service, repairs, maintenance or overhaul or, to the
          extent permitted by Section 4(e) hereof, for alterations or
          modifications;

               (iii) subject any Engine to normal interchange or pooling
          agreements or arrangements of the type customary in the United States
          airline industry and entered into by the Company or the Lessee in the
          ordinary course of business that do not contemplate or require the
          transfer of title to, or use for the remainder of the useful life of,
          any such Engine; provided, however, that if the Company's title to or
          use for the remainder of its useful life of any Engine shall be
          divested under any such agreement or arrangement, such divesture shall
          be deemed to be an Event of Loss with respect to such Engine and the
          Company shall comply with Section 4(f) in respect thereof;

               (iv) install Engine on an airframe that is owned by the Lessee,
          provided that such airframe is free and clear of all Liens on property
          of the Lessee except (A) Liens permitted under the Lease, (B) Liens
          that apply only to the engines (other than the Engines), appliances,
          parts, instruments, appurtenances, accessories, furnishings and other
          equipment (other than Parts) installed on such airframe (but not to
          the airframe as an entirety), and (C) the rights of any Domestic Air
          Carrier, under normal interchange agreements which are customary in
          the airline industry and do not contemplate or require the transfer of
          title to such airframe or the engines installed thereon;


<PAGE>
                                      -11-


               (v) install Engine on an airframe leased to the Lessee or owned
          by the Lessee subject to a conditional sale or other security
          agreement, provided that: (A) such airframe is free and clear of all
          Liens, except the rights of the parties to the lease or conditional
          sale or other security agreement covering such airframe and except
          Liens of the type permitted by clause (iv) above and (B) the Agent
          shall have received from the lessor, conditional vendor or secured
          party and each of the purchasers, mortgagees and encumbrancers of such
          lessor, conditional vendor or secured party of such airframe a written
          agreement (which may be the lease, conditional sale agreement or
          mortgage covering such airframe), whereby such lessor, conditional
          vendor or secured party and each of the purchasers, mortgagees and
          encumbrancers of such lessor, conditional vendor or secured party
          expressly and effectively agrees that neither it nor its successors
          and assigns will acquire or claim any right, title or interest in any
          Engine by reason of such Engine being installed on such airframe at
          any time when such Engine is subject to this Mortgage;

               (vi) install Engine on an airframe owned or leased by the Lessee
          subject to a conditional sale or other security agreement under
          circumstances where neither clause (iv) nor clause (v) above is
          applicable; provided, that any divesture of title to such Engine
          resulting from such installation shall be deemed to be an Event of
          Loss with respect to such Engine and the Company shall comply with
          Section 4(f) in respect thereof;

               (vii) authorize or permit the Lessee to enter into an ACMI
          Contract or wet lease for any Engine with any third party pursuant to
          which the Company has operational control of the Engines installed
          thereon, such operation to be performed solely by individuals under
          the operational control of the Company possessing all current
          certificates and licenses that would be required under the applicable
          laws of the United States for the performance by such employees of
          similar functions within the United States; provided, that the
          Company's obligations hereunder shall continue in full force and
          effect notwithstanding any such ACMI Contract or wet lease;

          provided, however, that the rights of any transferee who receives
          possession of any Engine permitted by the terms hereof shall be made
          subject and subordinate to, and the Leases shall be made expressly
          subject and subordinate to, the lien and security interest of this
          Mortgage and all of the Agent's rights hereunder and the Company shall
          remain primarily liable hereunder for the performance of all the terms
          of this Mortgage to the same extent as if such transfer had not
          occurred, and any such instrument of transfer shall include
          appropriate provisions for the maintenance and insurance of such
          Engine, and any such in-


<PAGE>
                                      -12-


          strument of transfer (other than the Lease) shall expressly prohibit
          any further transfer of such Engine or any assignment of the rights
          thereunder; and provided further, that no such lease, pooling
          arrangement or other transfer or relinquishment of the possession of
          any Engine shall in any way discharge or diminish any of the Company's
          obligations to the Agent hereunder or under the Credit Agreement. In
          the event that the Agent shall have received from the lessor,
          conditional vendor or secured party of any airframe leased to the
          Lessee or purchased by the Lessee subject to a conditional sale or
          other security agreement, a written agreement complying with clause
          (B) of Section 4(d)(v), and the lease or conditional sale or other
          security agreement covering such airframe also covers an engine,
          engines or spare engines owned by the lessor under such lease,
          conditionally owned by the conditional vendor under such conditional
          sale agreement, or subject to such security agreement, the Agent
          hereby agrees for the benefit of such lessor, conditional vendor or
          secured party that the Agent will not acquire or claim, as against
          such lessor, conditional vendor or secured party, any right, title or
          interest in any such engine or spare engine as the result of such
          engine or spare engine being installed on an airframe at any time
          while such engine or spare engine is subject to such lease or
          conditional sale or other security agreement and owned by such lessor,
          conditionally owned by such conditional vendor or subject to such
          security agreement.

          (e) Replacement and Pooling of Parts; Alterations, Modifications and
     Additions.

               (i) Except as otherwise provided in Section 4(e)(iv), the
          Company, at its own cost and expense, will promptly replace all Parts,
          that may from time to time be incorporated or installed in or attached
          to any Engine and that may from time to time become worn out, lost,
          stolen, destroyed, seized, confiscated, damaged beyond repair or
          permanently rendered unfit for use for any reason whatsoever. In
          addition, in the ordinary course of maintenance, service, repair or
          testing, the Company at its own cost and expense may remove any Parts,
          whether or not worn out, lost, stolen, destroyed, seized, confiscated,
          damaged beyond repair or permanently rendered unfit for use; provided,
          that, except as otherwise provided in Section 4(e)(iv), the Company at
          its own cost and expense shall replace such Parts as promptly as
          practicable. All replacement Parts shall be owned by the Company free
          and clear of all Liens (except Permitted Encumbrances and the Lease,
          and for pooling arrangements to the extent permitted by Section
          4(e)(ii)), and shall be in as good operating condition as, and shall
          have a value and utility at least equal to, the Parts replaced
          assuming such property were in the condition and repair required to be
          maintained by the terms hereof.


<PAGE>
                                      -13-


               All Parts at any time removed from any Engine shall remain the
          property of the Company and shall remain subject to the lien and
          security interest of this Mortgage, no matter where located until such
          time as such Parts shall be replaced by parts that have been
          incorporated or installed in or attached to any Engine and which meet
          the requirements for replacement parts specified above. Immediately
          upon any replacement Part becoming incorporated or installed in or
          attached to any Engine as above provided, without further act, (A)
          title to such replacement Part shall vest in and such replacement part
          shall become the property of the Company and shall become subject to
          the lien and security interest of this Mortgage and shall be deemed
          part of such Engine for all purposes hereof to the same extent as the
          property originally comprising, or installed on, such Engine, and (B)
          title to the replaced part shall no longer be the property of the
          Company and shall thereupon become free and clear of all rights of the
          Agent hereunder and shall no longer be deemed a Part hereunder.

               (ii) Any Part removed from any Engine as provided in Section
          4(e)(i) may be subjected by the Company or the Lessee to a normal
          pooling arrangement of the type customary in the airline industry
          entered into by the Lessee in the ordinary course of its business and
          entered into with Domestic Air Carriers that are not the subject of
          any bankruptcy, insolvency, or similar proceeding, voluntary or
          involuntary, provided that the Part replacing such removed Part shall
          be incorporated or installed in or attached to such Engine in
          accordance with Section 4(e)(i) as promptly as possible after the
          removal of such removed part. In addition, any replacement Part when
          incorporated or installed in or attached to any Engine in accordance
          with Section 4(e)(i) may be owned subject to such a pooling
          arrangement, provided that the Company, at its expense, as promptly
          thereafter as possible, either (A) causes such replacement Part to
          become subject to the lien and security interest of this Mortgage in
          accordance with Section 4(e)(i) by the Company's acquiring title
          thereto for the benefit of the Agent free and clear of all Liens
          (except Permitted Encumbrances and the Lease) or (B) replaces such
          replacement Part by incorporating or installing in or attaching to
          such Engine a further replacement Part owned by the Company free and
          clear of all Liens (except Permitted Encumbrances and the Lease).

               (iii) The Company, at its own cost and expense, shall make or
          cause to be made such alterations and modifications in and additions
          to the Engines as may be required from time to time to meet the
          standards of the FAA or other governmental authority having
          jurisdiction; provided, that the Company may, in good faith, contest
          the validity or application of any such standard in any reasonable
          matter that shall not adversely affect the Lien of this Mortgage or
          Lenders' interests therein. The Company also agrees, at its own cost
          and expense, to make or cause to be made such alterations and
          modifications in and additions to the Engines as may be required from
          time to


<PAGE>
                                      -14-


          time to meet the standards or requirements of any directive issued by
          a manufacturer relating to any Engine. In addition, so long as no
          Potential Event of Default or Event of Default shall have occurred and
          be continuing, the Company, at its own cost and expense, may from time
          to time make such alterations and modifications in and additions to
          any Engine as the Company may deem desirable in the proper conduct of
          its business or to accommodate the business of the Lessee, provided
          that no such alteration, modification or addition diminishes the value
          or utility or impairs the condition or airworthiness of such Engine
          below the value, utility, condition or airworthiness thereof
          immediately prior to such alteration, modification or addition,
          assuming that such Engine were then in the condition and airworthiness
          required to be maintained by the terms of this Mortgage.

               (iv) All Parts incorporated or installed in or attached to or
          added to any Engine as the result of such alteration, modification or
          addition shall, without further act, become the property of, and title
          to such parts shall vest in the Company and shall be subject to the
          lien and security interest of this Mortgage; provided, that, so long
          as no Potential Event of Default or Event of Default shall have
          occurred and be continuing, the Company may remove and not replace any
          such Part if it (A) is in addition to, and not in replacement of or in
          substitution for, any Part incorporated or installed in or attached to
          such Engine on the date hereof, on the date the Engine first becomes
          subject to the lien of this Mortgage, or any Part in replacement of or
          substitution for any such Part, (B) is not required to be incorporated
          or installed in or attached or added to such Engine pursuant to the
          terms of Section 4(c) hereof or any other provision of this Mortgage
          and (C) can be removed from such Engine without diminishing or
          impairing the value, utility or airworthiness that such Engine would
          have had at such time had such alteration, modification or addition
          not occurred, assuming that the Spare Engine was otherwise in the
          condition required by this Mortgage. Upon the removal by the Company
          of any such Part, as above provided, title thereto shall, without
          further act, be free and clear of all rights of the Agent hereunder
          and such Part shall no longer be deemed a Part hereunder.

               (v) The Company will ensure that, pursuant to the terms of the
          Lease, all obligations of the Company pursuant to this Section 4(e)
          shall be performed by the Lessee, at the Lessee's own cost and
          expense, and all Parts and alterations, improvements or modifications
          in and additions to any of the Engines shall become subject to the
          Lien of this Mortgage and shall be leased to the Lessee under the
          applicable Lease.

          (f) Event of Loss.

               (i) If an Event of Loss shall occur with respect to any Engine,
          the Company will promptly notify the Agent thereof in writing (in any
          event within five (5) days of


<PAGE>
                                      -15-


          such occurrence) and will, not later than 180 days after the receipt
          of Proceeds in connection with such Event of Loss, mortgage hereunder,
          by complying with all of the terms of subsection (ii) below and
          otherwise taking all necessary actions to provide that the Company
          (and the Agent upon foreclosure of the Company's interest in the
          Lease) will continue to be entitled to the benefits of Section 1110 of
          the Bankruptcy Code with respect to the replacement engine referred to
          below, an Acceptable Alternate Engine free of all Liens (other than
          Permitted Encumbrances and the Lease). Upon compliance with the
          preceding sentence within such 180-day period, the Agent will execute
          and deliver to the Company a partial release, in recordable form,
          releasing the lien of this Mortgage to the extent that it covers such
          Engine with respect to which such Event of Loss has occurred. Such
          Acceptable Alternate Engine shall thereupon constitute an "Engine" for
          all purposes hereof and shall be deemed to constitute part of the
          Spare Engine Collateral.

               (ii) Whenever the Company shall subject any Engine to the lien
          and security interest of this Mortgage (as contemplated by paragraph
          (i) above), the Company will on or prior thereto:

                    (A) deliver to the Agent and duly file for recording under
               the Act, a Supplemental Chattel Mortgage substantially in the
               form of Exhibit A hereto duly executed by the Company
               appropriately describing such engine to be subjected to the lien
               and security interest of this Mortgage;

                    (B) deliver to the Agent for filing financing statements
               under Article 9 of the Uniform Commercial Code of the States of
               Colorado and New York (or such other States as may be required at
               such time) covering the security interest created by this
               Mortgage to perfect the security interest of the Agent in the
               Engine to be subjected to the lien and security interest of this
               Mortgage;

                    (C) deliver to the Agent an Officers' Certificate dated the
               date of execution of said Supplemental Chattel Mortgage, stating:

                         (I) that the representations and warranties contained
                    in Section 3 hereof are true and correct on and as of such
                    date of execution with respect to such Engine and the
                    Company;

                         (II) that, upon consummation of the terms of this
                    Section 4(f), no Potential Event of Default or Event of
                    Default will exist; and


<PAGE>
                                      -16-


                         (III) that all conditions precedent contemplated in
                    this Section 4(f)(ii) have been complied with;

                    (D) furnish the Agent with evidence of compliance with the
               insurance provisions of Section 4(g) hereof with respect to such
               Engine as the Agent may reasonably request;

                    (E) furnish the Agent with a warranty (as to title) bill of
               sale, in form and substance reasonably satisfactory to the Agent
               with respect to such Engine;

                    (F) furnish the Agent with such evidence of title such as
               the bill of sale as the Agent may reasonably request concerning
               such Engine;

                    (G) cause to be delivered to the Agent an appraisal by the
               Approved Appraisers relating to the Engine to be subjected to the
               lien and the security interest of this Mortgage stating that it
               has a value and utility at least equal to, and in as good
               operating condition as the Engine subject to such Event of Loss
               immediately prior to such Event of Loss, assuming compliance by
               the Company with all the terms of this Mortgage with respect to
               such Engine; and

                    (H) cause to be delivered to the Agent an opinion or
               opinions of counsel dated the date of execution of such
               Supplemental Chattel Mortgage, stating:

                         (I) that the Engine specifically described in said
                    Supplemental Chattel Mortgage, is free and clear of all
                    recorded Liens,

                         (II) that said Supplemental Chattel Mortgage (1) has
                    been duly authorized, executed and delivered by Company, and
                    (2) creates a valid, perfected and first priority security
                    interest in and to the Engine described in said Supplemental
                    Chattel Mortgage, enforceable against all third parties and
                    securing the payment of all obligations purported to be
                    secured thereby and that all action required to perfect
                    fully such security interest has been taken and completed,

                         (III) that said Supplemental Chattel Mortgage has been
                    duly filed for recordation in accordance with the provisions
                    of the Act to continue the perfection and priority of the
                    security interest intended to be created by the Mortgage,

                         (IV) that the Company (and the Agent upon succeeding to
                    the Company's interest in the Lease) will continue to be
                    entitled to the benefits of Section 1110 of the Bankruptcy
                    Code with respect to the lease of the Engine described in
                    said Supplemental Chattel Mortgage, and

                         (V) as to such other matters as the Agent may
                    reasonably request.

                  Promptly upon the recording of each Supplemental Chattel
         Mortgage under the Act, the Company will cause to be delivered to the
         Agent an opinion of counsel for the Company as to the due recording of
         such Supplemental Chattel Mortgage in accordance with the Act.

               (iii) With respect to any Engine as between the Agent and the
          Company, any payments on account of an Event of Loss (other than
          insurance proceeds or other payments the application of which is
          provided for in Section 4(g) below and under the terms of the Credit
          Agreement) received from any government authority or other person
          shall be applied as follows:

                    (A) if such payments are received with respect to an Event
               of Loss to an Engine that has been or is being replaced by the
               Company pursuant to the terms hereof, so long as there shall
               exist no Event of Default or Potential Event of Default, such
               payment shall be paid over to or retained by the Company or the
               Lessee upon satisfaction of the conditions for replacement
               contained in paragraph (ii) above and until such time shall be
               held by the Agent in accordance with the provisions hereof as
               security for the Secured Obligations; and

                    (B) if such payments are received with respect to an Event
               of Loss with respect to which no replacement is being effected,
               such payments shall be applied to the prepayment of the Notes
               required pursuant to the terms of the Credit Agreement and shall
               be held pursuant to the terms of this Mortgage, and the balance,
               if any, shall be paid over to or retained by the Company.

               (iv) In the event of a requisition for use by the United States
          Government of any Engine, the Company shall promptly notify the Agent
          of such requisition and all of the Company's obligations under this
          Mortgage shall continue to the same extent as if such requisition had
          not occurred. Any payments received by the Agent or the Company from
          the United States Government for the use of such Engine, shall be paid
          over to, or retained by, the Company.

                                      -18-


               (v) Any amount referred to in paragraph (iii) or (iv) of this
          Section 4(f) that is payable to or retained by the Company shall not
          be paid to the Company or retained by the Company, if at the time of
          such payment or retention any Event of Default or a Potential Event of
          Default shall have occurred and be continuing, but shall be held by or
          paid over to the Agent as security for the obligations of the Company
          under this Mortgage and the other Loan Documents, and, if the Agent
          shall declare the Credit Agreement to be in default, shall be applied
          against the Company's obligations hereunder and thereunder as and when
          due. At such time as there shall not be continuing any such Event of
          Default or Potential Event of Default, such amount shall be paid to
          the Company to the extent not previously applied in accordance with
          the preceding sentence. In addition, and whether or not there shall
          exist an Event of Default or Potential Event of Default, until such
          time as the Company shall request to be paid any amount referred to in
          paragraph (iii) or (iv) in order to effect the mortgaging hereunder of
          a replacement Engine, any amounts referred to in paragraphs (iii) or
          (iv) of this Section 4(f) shall be held by the Agent as security for
          the obligations of the Company under this Mortgage and the other Loan
          Documents.

     (g) Insurance.

               (i) The Company will cause the Lessee at all times to carry and
          maintain on or with respect to the Engines, at the Lessee's own cost
          and expense, public liability (including without limitation,
          contractual liability, cargo liability, passenger legal liability,
          bodily injury and product liability, but excluding manufacturer's
          product liability) and property damage insurance with insurers of
          recognized responsibility and reputation in amounts, of the type and
          covering the risks customarily carried with respect to similar
          equipment by corporations engaged in the same or similar business and
          similarly situated with the Lessee but in no event in an amount less
          than $500,000,000 per occurrence (which shall include war risk,
          governmental confiscation and expropriation and allied perils
          coverage). During any period when the Engines are on the ground and
          not in operation, the Lessee may carry or cause to be carried, in lieu
          of insurance required by this Section, insurance otherwise conforming
          with the provisions of this Section except that the amounts of
          coverage shall not be required to exceed the amounts of comprehensive
          airline liability insurance, and the scope of risk covered and type of
          insurance shall be the same, as are customarily carried with respect
          to similar equipment on the ground by corporations engaged in the same
          or similar business and similarly situated with the Lessee. Any
          policies of insurance carried in accordance with this Section 4(g) and
          any policies taken out in substitution or replacement of any such
          policies (A) shall be amended to name the Agent and the Lenders as
          additional named insureds, (B) shall be primary without right of
          contribution from any other insurance which is carried by the Lessee,
          (C) shall expressly pro-


<PAGE>
                                      -19-


          vide that all provisions thereof, except the limits of the liability,
          shall operate in the same manner as if there were a separate policy
          covering each insured, and (D) shall provide that the insurer shall
          waive any right of subrogation against the Agent or the Lenders.

               (ii) The Company will cause the Lessee at all times to carry and
          maintain with insurers of recognized responsibility and reputation on
          or with respect to the Engines, at the Lessee's own cost and expense,
          aircraft ground and flight all-risk hull insurance as well as fire and
          extended coverage insurance on the Engines and other equipment while
          removed from an airframe (which shall include war risk, governmental
          confiscation and expropriation (other than by the United States
          Government) and allied perils including (A) strikes, riots, civil
          commotions or labor disturbances, (B) any malicious act or act of
          sabotage and (C) hijacking (air piracy) or any unlawful seizure or
          wrongful exercise of control of the aircraft on which any Engine is
          installed or crew of such aircraft in flight (including any attempt at
          such seizure or control) made by any person or persons aboard such
          aircraft acting without the consent of the insured, if and to the
          extent the same shall be maintained by the Lessee with respect to
          similar equipment owned or operated by the Lessee on the same routes
          or if such aircraft is operated on routes where the custom is for
          Domestic Carriers similarly situated with the Lessee flying comparable
          routes with similar equipment to carry such insurance, of the type
          usually carried by corporations engaged in the same or similar
          business and similarly situated with the Lessee; provided, that such
          insurance (including any self-insurance to the extent --------
          permitted below) shall at all times be for an amount not less than the
          greater of the amount required by the applicable Lease and $3,000,000
          per Engine. During any period when an Engine is on the ground and not
          in operation the Lessee may carry or cause to be carried, in lieu of
          the insurance required by this Section, insurance otherwise conforming
          hereto except that the scope of risk covered and type of insurance
          shall be the same as are from time to time customarily carried with
          respect to similar spare engines by corporations engaged in the same
          or similar business and similarly situated with the Lessee for spare
          engines on the ground in an amount at least equal to the applicable
          amount provided above. All such insurance shall name the Agent and the
          Lenders as additional insureds and loss payees to the extent their
          interest may appear and shall provide that any loss to an Engine in
          excess of $2,000,000 (and, if a Potential Event of Default or Event of
          Default has occurred and is continuing, any such loss) shall be
          payable to the Agent for the benefit of the Lenders; and shall be
          primary without right of contribution from any other insurance that is
          carried by the Agent with respect to its interest therein.

               The Lessee may self-insure, by way of deductible or equivalent
          provisions in insurance policies, the risks required to be insured
          against pursuant to this Section


<PAGE>
                                      -20-


          4(g)(ii) in such reasonable amounts as are then applicable to other
          similar spare engines in the Lessee's fleet that are of a value
          comparable to the Engines, and as are not substantially greater than
          amounts self-insured by corporations engaged in the same or similar
          business and similarly situated with the Lessee; provided, however,
          that the Company shall not permit the Lessee to self-insure in an
          amount in excess of $1,000,000 without the prior written consent of
          the Agent.

               (iii) Any policies of insurance required pursuant to either
          paragraph (i) or paragraph (ii) above shall: (A) be amended to name
          the Agent and the Lenders as additional named insureds, but without
          the Agent or the Lenders being thereby liable for premiums; (B)
          provide that in respect of the interest of the Agent or the Lenders in
          such policies the insurance shall not be invalidated by any action or
          inaction of the Lessee and shall insure the interests of the Agent and
          the Lenders regardless of any breach or violation by the Lessee or any
          Person (other than the Agent) of any warranty, declaration or
          condition contained in such policies; (C) provide that if such
          insurance is cancelled, or if any material change is made in the
          coverage that affects the interest of the Agent or any Lender, or if
          such insurance is allowed to lapse for nonpayment of premium, such
          cancellation, change or lapse shall not be effective as to the Agent
          for thirty (30) days (seven (7) days, or such shorter or longer period
          as may from time to time be customarily available in the industry, in
          the case of any war risk and allied perils coverage) after receipt by
          the Agent of written notice from such insurers of such cancellation,
          change or lapse; (D) be in full force and effect throughout any
          geographical areas at any time traversed by any of the Engines and
          shall be payable in U.S. dollars; (E) waive any right of the insurers
          to any setoff or counterclaim or any other deduction, whether by
          attachment or otherwise in respect of any liability of the Agent; and
          (F) waive all rights of subrogation against the Agent.

               (iv) In the case of a lease or contract with the United States or
          any agency or instrumentality thereof in respect of any Engine, a
          valid agreement by the United States or such agency or instrumentality
          to indemnify the Lessee against the same risks against which the
          Lessee is required hereunder to insure shall be considered adequate
          insurance with respect to such Engine to the extent of the risks and
          in the amounts that are the subject of any such agreement to
          indemnify.

               (v) On or prior to the date hereof, and annually thereafter on or
          prior to January 31, the Company will cause the Lessee to furnish to
          the Agent (A) a report signed by a firm of independent aircraft
          insurance brokers, appointed by the Lessee and not objected to by the
          Agent, describing in reasonable detail acceptable to the Agent the
          insurance then carried and maintained on or with respect to the
          Engines and stating that in the opinion of such firm such insurance
          complies with the terms of this Section 4(g) and is adequate to
          protect the interests of the Lessee, the Company and


<PAGE>
                                      -21-


          the Agent, and (B) certificates of the insurer or insurers evidencing
          the insurance covered by the report. The Company will cause the Lessee
          to cause such brokers to advise the Agent in writing (x) promptly of
          any default in the payment of any premium and of any other act or
          omission on the part of the Lessee of which such firm has knowledge
          and which might invalidate or render unenforceable, in whole or in
          part, any insurance on any Engine and (y) at least thirty (30) days
          prior to the expiration or termination date, or date of effectiveness
          of any material change, of any insurance carried and maintained on the
          Engines hereunder.

               (vi) All insurance payments and other payments received by the
          Agent or the Company from insurance referred to in paragraph (ii)
          above shall be, if received by the Company, immediately paid to the
          Agent and shall be held by the Agent as security for the Secured
          Obligations and all other obligations required to be paid in
          accordance with the terms of this Mortgage and the Credit Agreement
          and such payments shall be paid to the Company upon compliance by the
          Company with the terms of Subsection 4(f) with respect to the
          replacement of an engine, provided that no Potential Event of Default
          or Event of Default shall have occurred and be continuing.

               All insurance payments and other payments received by the Agent
          or the Company from insurance referred to in paragraph (ii) above and
          paid other than as a result of an Event of Loss shall be paid by the
          Agent to or be retained by the Company, and promptly applied by the
          Company to the extent necessary to repair the damage to the Engine for
          which such insurance was paid, provided that the Agent shall not be
          required to make any such payment to the Company if a Potential Event
          of Default or Event of Default has occurred and is continuing, but
          shall be held or paid over to the Agent as security for the
          obligations of the Company under this Mortgage and the other Loan
          Documents, and, if the Agent shall declare the Credit Agreement to be
          in default, shall be applied against the Company's obligations
          hereunder and thereunder as and when due. Retention by the Agent of
          any amounts pursuant to the preceding sentence shall not relieve the
          Company of its obligations to make promptly all repairs and
          replacements required by Sections 4(c) and (e) hereof and to pay for
          the same with the Company's funds or cause payment of the same under
          the Lease by the Lessee.

               (vii) Nothing in this Section 4(g) shall prohibit the Agent or
          any Lender from obtaining insurance with respect to any Engine for its
          own account. The Company may, at its own expense, carry insurance with
          respect to its interest in any Engine in amounts in excess of that
          required to be maintained by this Section 4(g). No insurance
          maintained by the Agent or any Lender shall prevent the Company from
          causing the Lessee to carry the insurance required or permitted by
          this Section or adversely affect such insurance or the cost thereof.
          Proceeds of any such insurance carried by the


<PAGE>
                                      -22-


          Agent or any Lender shall be paid as provided in the insurance policy
          relating thereto and the Agent shall have no duty to obtain any such
          insurance.

          (h) Inspection. The Company will permit, and cause the Lessee to
     permit, any officers, employees or authorized representatives of the Agent
     to inspect, at the Lessee's cost and expense under the Lease, the Spare
     Engine Collateral and Spare Engine Related Collateral, or any part thereof,
     and to examine, copy or make extracts from, any and all books, records and
     documents in the possession of the Company relating to such Collateral or
     any part thereof and performance of this Mortgage, all at such reasonable
     times and as often as may be requested. The Agent shall have no duty to
     make any such inspection or examination and shall not incur any liability
     or obligation by reason of making or not making any such inspection or
     examination.

          (i) Insignia. The Company shall, at its own cost and expense, or
     pursuant to the Lease, cause each Engine included in the Spare Engine
     Collateral to be legibly marked (in a reasonably prominent location) with
     such a plate, disk, or other marking of customary size, and bearing the
     legend "Owned by Atlas Freighter Leasing III, Inc., and Mortgaged to
     Bankers Trust Company, as Agent" or such other legend, as shall in the
     opinion of the Agent be appropriate or desirable to evidence the fact that
     it is subject to the lien and security interest created by this Mortgage.
     The Company shall not remove or deface, or permit to be removed or defaced,
     any such plate, disk, or other marking or the identifying manufacturer's
     serial number, and, in the event of such removal or defacement, shall
     promptly cause such plate, disk, or other marking or serial number to be
     promptly replaced. Except as provided above, the Company shall not allow
     the name of any person, association or corporation to be placed on any
     Engine as a designation that might be interpreted as a claim of ownership
     or of any security interest therein, except that any permitted lessee may
     place its customary colors and insignia or the insignia of the manufacturer
     on any Engine.

SECTION 5. Remedies.

     (a) If any Event of Default shall occur and be continuing, then the Agent
may, without notice of any kind to the Company, exercise in respect of the Spare
Engine Collateral and Spare Engine Related Collateral, (i) all the rights and
remedies of a secured party on default under the Uniform Commercial Code as in
effect at the time in any applicable jurisdiction (whether or not the Uniform
Commercial Code applies to the affected Spare Engine Collateral), (ii) any and
all remedies under the Leases and all of the rights and remedies of the Lessor
under the Lease, (iii) all the rights and remedies provided for in this
Mortgage, the Credit Agreement and any other Loan Document, and in any other
agreement between the Company and the Agent, and (iv) such other rights and
remedies as may be provided by law or otherwise.


<PAGE>
                                      -23-


     (b) After an Event of Default has occurred and is continuing, the Agent
may, without notice, take possession of the Spare Engine Collateral or any part
thereof and may exclude the Company and the Lessee, and all persons claiming
under the Company or the Lessee, wholly or partly therefrom. At the request of
the Agent, the Company shall promptly deliver or cause the Lessee to deliver to
the Agent or to whomsoever the Agent shall designate, at such time or times and
place or places as the Agent may specify, and fly or cause to be flown to such
airport or airports in the United States as the Agent may specify, without risk
or expense to the Agent, the Spare Engine Collateral or any part thereof. In
addition, the Company will provide, or cause the Lessee to provide, without cost
or expense to the Agent, storage facilities for the Spare Engine Collateral. If
the Company or the Lessee shall for any reason fail to deliver the Spare Engine
Collateral or any part thereof after demand by the Agent, the Agent may, without
being responsible for loss or damage, (i) obtain a judgment conferring on the
Agent the right to immediate possession or requiring the Company and the Lessee
to deliver immediate possession of the Spare Engine Collateral or any part
thereof to the Agent, the entry of which judgment the Company hereby
specifically consents and the Lessor's consent to which will be obtained by the
Company under the Lease, or (ii) with or without such judgment, pursue the Spare
Engine Collateral or any part thereof wherever it may be found and may enter any
of the premises of the Company and the Lessee where the Spare Engine Collateral
may be and search for the Spare Engine Collateral and take possession of and
remove the same. The Company agrees to pay to the Agent, upon demand, all
expenses incurred in taking any such action; and all such expenses shall, until
paid, be secured by the lien of this Mortgage. Upon every such taking of
possession, the Agent may, from time to time, make all such reasonable
expenditures for maintenance, insurance, repairs, replacements, alterations,
additions and improvements to and of the Spare Engine Collateral, as it may deem
proper. In each such case, the Agent shall have the right to maintain, use,
operate, store, lease, control or manage the Spare Engine Collateral or any part
thereof and to carry on the business and exercise all rights and powers of
Company relating to the Spare Engine Collateral, as the Agent shall deem best,
including the right to enter into any and all such agreements with respect to
the maintenance, use, operation, storage, leasing, control, management or
disposition of the Spare Engine Collateral or any part thereof as the Agent may
determine. Further, after the occurrence and during the continuation of an Event
of Default, the Agent shall be entitled to collect and receive directly all
tolls, rents, revenues, issues, income, products and profits of the Spare Engine
Collateral or any part thereof, including without limitation, all payments under
any of the Leases. Such tolls, rents, revenues, issues, income, products and
profits shall be applied to pay the expenses of the use, operation, storage,
leasing, control, management or disposition of the Spare Engine Collateral, and
of all maintenance, insurance, repairs, replacements, alterations, additions and
improvements, and to make all payments that the Agent may be required or may
elect to make, if any, for taxes, assessments, or other proper charges upon the
Spare Engine Collateral and all other payments that the Agent may be required or
authorized to make under any provision of this Mortgage, as well as just and
reasonable com-

                                      -24-


pensation for the services of the Agent and of all persons properly engaged and
employed for such purposes by the Agent.

     (c) The Agent, with or without taking possession of the Spare Engine
Collateral, may, without notice:

          (i) to the extent permitted by law, sell at one or more sales, as an
     entirety or in separate lots or parcels, the Spare Engine Collateral or any
     part thereof, at public or private sale, at such place or places and at
     such time or times and upon such terms, including terms of credit (which
     may include the retention of title by the Agent to the property so sold),
     as the Agent may determine, whether or not the Spare Engine Collateral
     shall be at the place of sale; and

          (ii) proceed to protect and enforce its rights under this Mortgage by
     suit, whether for specific performance of any covenant herein contained or
     in aid of the exercise of any power herein granted or for the foreclosure
     of this Mortgage and the sale of the Spare Engine Collateral under the
     judgment or decree of a court of competent jurisdiction or for the
     enforcement of any other right.

     (d) After an Event of Default has occurred and is continuing, the Company
agrees to the fullest extent that it lawfully may, that it and the Lessee will
not (and hereby irrevocably waives its right to) at any time plead, or claim the
benefit or advantage of, any appraisement, valuation, stay, extension,
moratorium, or redemption law now or hereafter in force, in order to prevent or
hinder the enforcement of this Mortgage or the absolute sale of the Spare Engine
Collateral. The Company, for itself and all who may claim under it, waives, to
the extent that it lawfully may, all right to have all or any portion of the
Spare Engine Collateral marshalled upon any foreclosure hereof.

     (e) Each and every remedy of the Agent shall be cumulative and shall not be
exclusive of any other remedies provided now or hereafter at law, in equity or
otherwise. The Company shall reimburse the Agent, upon demand, for all fees and
other expenses paid or incurred by the Agent in exercising any rights, powers or
remedies granted hereby. All such fees and expenses shall, until paid, be
secured by the lien of this Mortgage.

     (f) Notwithstanding anything to the contrary contained in this Mortgage or
the Lease, the Agent shall at all times have the right, to the exclusion of the
Company, to declare the Lease in default in accordance with its terms and to
exercise all remedies set forth in the Leases.

     remainder.

other instruments in connection with any such sale, lease or other disposition,
and (iv) generally to do, at the Agent's option and the Company's cost and
expense, at any time, or from time to time, all acts and things that the Agent
deems necessary to protect, preserve or realize upon the Spare Engine Collateral
and Spare Engine Related Collateral and the Agent's security interest therein,
in order to effect the intent of this Mortgage, all as fully and effectively as
the Company might do, the Company hereby ratifying and confirming all that its
said attorney (or any substitute) shall lawfully do hereunder and pursuant
hereto.

SECTION 8. Cash Collateral.

     All monies received by the Agent to be held and applied under this Section,
and all monies if any, required to be paid to the Agent hereunder, which
disposition is not elsewhere herein otherwise specifically provided for, shall
be held by the Agent and applied from time to time as provided herein and in the
Credit Agreement and the other Loan Documents and shall be held in an account in
the name of the Agent and invested in Cash Equivalents for the benefit and at
the risk of the Company.

SECTION 9. Agent's Right to Perform.

     If the Company fails to make any payment required to be made by it
hereunder or fails to perform or comply with any of its agreements contained
herein, the Agent may itself make such payment or perform or comply with such
agreement (including, without limitation, the agreement of the Company to
maintain insurance pursuant to Section 4(g) hereof), and the amount of such
payment and the amount of the reasonable expenses of the Agent incurred in
connection with such payment or the performance of or compliance with such
agreement, as the case may be, together with interest thereon at the rate
specified in the Credit Agreement from time to time, shall be payable by the
Company to the Agent on demand and shall constitute additional indebtedness
secured by the lien and security interest of this Mortgage.

SECTION 10. Further Assurances.

     The Company at its expense will promptly and duly execute and deliver such
documents and assurances and take such action as may be necessary or desirable,
or as the Agent may from time to time request, in order to correct any defect,
error or omission which may at any time hereafter be discovered in the contents
of this Mortgage or in the execution or delivery hereof, and/or in order to more
effectively carry out the intent and purpose of this Mortgage and to establish,
protect and perfect the rights, remedies and security interests created or
intended to be created in favor of the Agent hereunder, including, without
limitation, the execution, delivery and filing of any instruments with the FAA

<PAGE>
                                      -27-


mercial Code financing and continuation statements with respect to the security
interests created hereby, in form and substance satisfactory to the Agent, in
such jurisdictions as the Agent may reasonably request. The Company hereby
authorizes the Agent to file any such statements without the signature of the
Company to the extent permitted by applicable law.

SECTION 11. Continuing Security Interest.

     This Mortgage shall create a continuing security interest in the Spare
Engine Collateral and Spare Engine Related Collateral and shall (a) remain in
full force and effect until the indefeasible payment in full of the Secured
Obligations, (b) be binding upon the Company, its successors and assigns and (c)
inure, together with the rights and remedies of the Agent hereunder, to the
benefit of the Agent and its successors, transferees and assigns. Without
limiting the generality of the foregoing clause (c), the Agent or any Lender
may, subject to any restrictions contained in the Credit Agreement, assign or
otherwise transfer any of its interests in the Credit Agreement or in any Note
to any other person or entity, and such other benefits in respect thereof
granted to the Agent or any Lender herein or otherwise. Upon the indefeasible
payment in full of the Secured Obligations, the security interest granted hereby
shall terminate and all rights to the Spare Engine Collateral and Spare Engine
Related Collateral shall revert to Company. Upon any such termination, the Agent
will execute and deliver to the Company, at the Company's expense, such
instruments of release and termination as the Company may reasonably request to
evidence such termination.

SECTION 12. Miscellaneous.

     Any provision of this Mortgage 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, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. To the extent permitted by applicable law, the Company
hereby waives any provision of law which renders any provision hereof prohibited
or unenforceable in any respect. No term or provision of this Mortgage may be
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the Company and the Agent. The captions and headings in this
Mortgage are for convenience of reference only and shall not define or limit any
of the terms or provisions hereof.

SECTION 13. Consent to Jurisdiction and Service of Process.

     All judicial proceedings brought against the Company with respect to this
Mortgage may be brought in any state or federal court of competent jurisdiction
in the State of New York or Colorado and by execution and delivery of this

Collateral and Spare Engine Related Collateral,

                                      -28-


generally and unconditionally, the nonexclusive jurisdiction of the aforesaid
courts and irrevocably agrees to be bound by any judgment rendered thereby in
connection with this Mortgage. The Company hereby agrees that service of process
in any such proceeding in any such court may be made by registered or certified
mail return receipt requested to the Company at its address provided on the
signature pages of the Mortgage, such service being hereby acknowledged by the
Company to be effective and binding service in every respect. A copy of any such
process so served shall be mailed by registered mail to the Company, at its
address specified in Section 15 hereof, except that unless otherwise provided by
applicable law, any failure to mail such copy shall not affect the validity of
service of process. If any agent appointed by the Company refuses to accept
service, the Company hereby agrees that service upon it by mail shall constitute
sufficient notice. Nothing herein shall affect the right to serve process in any
other manner permitted by law or shall limit the right of the Agent to bring
proceedings against the Company in the courts of any other jurisdiction.

SECTION 14. GOVERNING LAW; TERMS.

     THIS MORTGAGE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAWS
