                 PURCHASE AND EXCHANGE OF FINEX NOTES; PAYMENTS

                 SECTION 2.01 -- Purchase and Exchange of Finex Notes.  Subject
to the satisfaction of the conditions precedent set forth in article VII, and
on the terms and conditions set forth in this article II, on the Purchase Date
for each Aircraft, Lender shall purchase the related Finex Note from Finex Bank
and Borrower will exchange with Lender a Note for such Finex Note.  The
Financed Amount for each Aircraft shall be the Equipment Cost for the related
Equipment Portion less the Downpayment for such Equipment Portion, but in no
event shall the combined Financed Amount for both Equipment Portions exceed the
Commitment.  Each Finex Note shall be purchased for its face amount and each
Note exchanged for such Finex Note shall have the same face amount as such
Finex Note.  Lender's Commitment to purchase the Finex Notes pursuant to this
Agreement shall expire at 12:00 noon, New York City time, on the last day of
the Commitment Period.

                 SECTION 2.02 -- Procedure for Purchase and Exchange of Finex
Notes.  The procedure to be followed in the purchase and exchange of Finex
Notes is described in Annex A.  At Lender's offices at 75 Wall Street, New
York, New York 10265 (or such other location as the parties hereto agree upon),
not later than 12:00 noon (New York City time) on the appropriate Purchase
Date, upon fulfillment of the conditions set forth in article VII and in
compliance with the procedures set forth in Annex A, Lender will purchase the
related Finex Note from Finex Bank (who will have purchased that Finex Note
simultaneously from Vendor), with general corporate funds, in each case for a
purchase price equal to its face amount (as set forth in section 2.01).
Concurrently therewith, Borrower will exchange with Lender a Note for such
Finex Note, such Note to have the same face amount as the related Finex Note.

                 SECTION 2.03 -- Commitment Fee.  In partial consideration of
the Lender's agreement to purchase and exchange the Finex Notes, Borrower shall
pay to Lender a Commitment Fee (""Commitment Fee") for the Commitment Period,
payable in arrears on the first day of each quarter or partial quarter (for the
prior quarter or partial quarter) after the execution and delivery of this
Agreement during the Commitment Period with a final payment on the last day of
the Commitment Period, and computed at a rate per annum (calculated on the
basis of a 360-day year and actual days elapsed) of 1/8 of 1% of the average
daily unused portion of Lender's Commitment.  The term "quarter" as used in
this Section shall mean the relevant calendar quarter ending on one of the
following dates: March 31, June 30, September 30, or December 31.

                 SECTION 2.04 -- Facility Fee.  In partial consideration of the

                 SECTION 3.01 -- Security Interest in Collateral.  To secure
Borrower's obligations to Lender under each Note and the other Basic Documents
to which it is or becomes a party, Borrower shall execute and deliver to
Lender, on each Purchase Date, a supplement to the Mortgage (a "Mortgage
Supplement"), substantially in the form of Schedule A to the Mortgage, granting
to Lender a perfected purchase money security interest in the Equipment Portion
being purchased from Vendor on such Purchase Date.

                 SECTION 3.02 -- Set-Off Rights.  If Borrower becomes
insolvent, or any Event of Default occurs, any indebtedness that Lender then
owes to Borrower and any other property of Borrower that Lender then holds may

Lender under the Basic Documents, whether or not any such other obligations is
then due.

                            PAYMENTS UNDER THE NOTES
                     AND OTHER AMOUNTS PAYABLE BY BORROWER

                 SECTION 4.01 -- How Payments Are Made.  Borrower shall make
its payments and prepayments of principal and interest due on the Notes, all
amounts due as Commitment Fees and Facility Fees hereunder, and all other
amounts payable by Borrower to Lender under the Basic Documents, to Lender at
the Federal Reserve Bank of New York, 1 Liberty Plaza, New York, New York,

notifies Borrower), in immediately available funds and in Dollars, no later
than 1:00 p.m. (New York City time) on the date when due.  Any payment made by
Borrower to Lender after 1:00 p.m. (New York City time) on any day shall be
deemed to have been made on the following Business Day.  If any payment due
under the Basic Documents comes due on a day which is not a Business Day, such
payment shall instead be made on the following Business Day, unless such
Business Day falls in another calendar month, in which case such payment shall
be made on the preceding Business Day, and interest, or Commitment Fees, as the
case may be, shall accrue at the applicable rate to the day of payment.

                 SECTION 4.02 -- Right to Prepay.  Unless a Default exists,
Borrower shall have the right to prepay in full the outstanding principal
amount of the Note issued with respect to any designated Equipment Portion,
without premium or penalty.  Borrower shall give to Lender at least 30 days'
prior written notice (which notice shall be irrevocable) of such prepayment.
Upon any prepayment of any Note under this section 4.02, Borrower shall pay all
accrued and unpaid interest on the principal of such Note to the date of
prepayment, together with all other amounts payable under section 10.02 with
respect to such prepayment.

                 SECTION 4.03 -- Mandatory Prepayments.  Following the
occurrence of an Event of Loss with respect to any Aircraft, Borrower shall
prepay the Note executed in connection with that Aircraft, in accordance with
section 7.01(b) of the Mortgage, and shall pay all other amounts payable under
section 10.02 with respect to such prepayment.  Upon acceleration of the Notes
pursuant to section 8.02, Borrower shall prepay such Notes, and shall

pay all other amounts payable under section 10.02 with respect to such
prepayment.

                 SECTION 4.04 -- Mandatory Purchase.  Upon the occurrence of a
Prepayment Event, Lender shall have the
<PAGE>   14
                                     -10-

right to require Borrower to purchase or cause the purchase of the relevant Note
for its then-outstanding principal amount, plus all accrued but unpaid interest
on such Note to the date of such purchase, together with all other amounts
payable under section 10.02 with respect to such prepayment.  The payment
described in the preceding sentence shall be due 10 days after a Prepayment
Event has occurred (if that Prepayment Event has not been cured by then), and
shall be made in the manner prescribed by section 4.01.  A "Prepayment Event"
shall occur if (a) Borrower fails to keep an Aircraft registered with the FAA;
or (b) Borrower fails to obtain an FAA standard airworthiness certificate for an
Aircraft within twenty days following the Purchase Date for such Aircraft.

                 SECTION 4.05 -- Amount of Prepayment.  A Note shall be deemed
satisfied in full upon the prepayment of all principal of such Note, the
payment of the interest due on or with respect to such Note on such prepayment
date, and the payment of all past-due interest on or with respect to such Note
and the payment of all other amounts payable under section 10.02 with respect
to such prepayment.

                 SECTION 4.06 -- Interest on Past Due Amounts.  Any amounts
past due (by acceleration or otherwise) and at any time outstanding under any
Note or from Borrower under any other Basic Document shall (to the extent
permitted by law) bear interest, payable on demand, from the due date until
payment in full, at a rate equal to 2% per annum above Borrower Interest Rate.


                                   ARTICLE V

                   BORROWER'S REPRESENTATIONS AND WARRANTIES

                 Borrower represents and warrants as follows:

                 SECTION 5.01 -- Corporate Standing.  Borrower is a duly
organized corporation existing in good standing under the laws of Georgia, has
the corporate power and legal authority to own or lease its properties and to
carry on its business as now conducted and as now proposed to be conducted, and
is duly qualified to do business in all jurisdictions wherein such
qualification is necessary

(except in any jurisdictions in which the failure to qualify would have no
materially adverse effect on its business or on its ability to carry out its
obligations under the Basic Documents to which it is (or is to become) a
party).

                 SECTION 5.02 -- Corporate Powers.  Borrower's execution,
delivery, and performance of the Basic Documents to
<PAGE>   15
                                     -11-

which it is (or is to become) a party are within Borrower's corporate powers;
and the Basic Documents to which it is (or is to become) a party have been duly
authorized by all necessary corporate action on Borrower's part, and do not
contravene, result in a breach of, or require any consent under any law,
judgment, decree, order, or contractual restriction binding on Borrower or any
agreement or instrument to which Borrower is a party or to which it or any of
its property is subject.

                 SECTION 5.03 -- Binding Effect.  The Basic Documents to which
Borrower is (or is to become) a party are (or will be when executed and
delivered) legal, valid, and binding obligations of Borrower in accordance with
their terms, except as may be limited by bankruptcy, insolvency, or other
similar laws affecting enforcement of creditors' rights generally.

                 SECTION 5.04 -- Litigation.  Except as disclosed in the SEC
Filings, there are no pending or (to the best of Borrower's knowledge after due
inquiry) threatened actions or proceedings before any court or administrative
agency which may be expected to have a materially adverse effect on Borrower's
business or financial condition or which seek to question or set aside any of
the transactions herein contemplated.

                 SECTION 5.05 -- Financial Statements.  The audited balance
sheet as of December 31, 1989 and unaudited balance sheet as of September 30,
1990 for Borrower and its consolidated subsidiaries, and the related results of
operations for the year and quarter then ended, have been prepared in
accordance with GAAP and correctly present Borrower's financial condition as of
such dates and results of operations for such periods, and since September 30,
1990, there has been no materially adverse change in Borrower's business,
assets, operations, or condition (financial or otherwise).

                 SECTION 5.06 -- Taxes.  Borrower has filed all tax returns
which it is or was required to file, and has paid all taxes shown to be due and
payable on those returns

or on any assessment received by it, except such taxes of Borrower, if any, as
are being contested diligently in good faith, and by appropriate proceedings,
and as to which adequate reserves have been provided in accordance with GAAP.

                 SECTION 5.07 -- Status as United States Citizen and Air
Carrier.  Borrower is a "citizen of the United States" as that term is used in
section 101(16) of the Act, and is a duly certified "air carrier" within the
meaning of the Act.

                 SECTION 5.08 -- Location of Offices.  Borrower's chief
executive office and principal place of business, and the place where Borrower
keeps its financial records
<PAGE>   16

                                     -12-

concerning the Collateral, is located at its address referred to in section
11.02.  The Spare Parts shall be located as set forth in Annex A to each
Mortgage Supplement, unless otherwise specified pursuant to section 4.05 of the
Mortgage.

                 SECTION 5.09 -- Governmental Consents.  Neither the execution,
delivery, and performance of any of the Basic Documents (other than the Finex
Agreement), nor the consummation of any of the transactions contemplated
thereby by Borrower or Vendor (including the importation of the Aircraft into
the United States from Brazil), requires the consent or approval of, giving of
notice to, registration with, or taking of any other action in respect of any
federal, state, or foreign governmental authority or agency (including any
judicial body) except for (a) the filing and recording of the Mortgage, and of
the FAA bill of sale, the FAA application for registration, and the Mortgage
Supplement for each Aircraft with the FAA; (b) the filing and recording of
UCC-1 financing statements for each Aircraft with the Superior Court Clerk
Offices in Bibb, Clayton, and Fulton County, Georgia, and in the appropriate
places in Texas and Arkansas; and (c) the registration of each Aircraft with
the FAA pursuant to the Act, and except for any necessary action with respect
to the Finex Program.

                 SECTION 5.10 -- Condition of Aircraft.  On each Purchase Date,
the Aircraft to be delivered on such Purchase Date shall be in such condition
as is sufficient to enable Borrower to obtain a standard U.S. certificate of
airworthiness for such Aircraft and to enable such airworthiness certificate to
be maintained in good standing; and, to Borrower's knowledge (which shall be
based on acceptance tests by Borrower in accordance with its ususal practices,
to the extent permitted under the Purchase Agreement), such Aircraft shall
otherwise conform in all material respects to the specifications for such
Aircraft set forth in the Purchase Agreement.

                 SECTION 5.11 -- Absence of ERISA Liability.  Each employee
pension benefit plan (as defined in section 3(2) of the Employee Retirement
Income Security Act of 1974, as from time to time amended ("ERISA")) of
Borrower is in compliance with the applicable provisions of ERISA and of the
Internal Revenue Code of 1986, as from time to time amended, in all respects,
except the extent that noncompliance would not be materially adverse to
Borrower's business, assets, financial condition, or ability to perform its
obligations under the Basic Documents.

                 SECTION 5.12 -- Delta Agreement.  The Delta Agreement is (a)
the only agreement to which the Borrower is a party relating to joint marketing
or code sharing for interconnecting flights, and (b) in full force and effect.
There exists no default under the terms of the Delta Agreement and there has
not occurred any event that would
<PAGE>   17

                                     -13-

ripen into a default upon the giving of notice or passage of time.

                 SECTION 5.13 -- Subsidiaries; Stock Ownership.  Borrower owns
100% of the outstanding stock of Guarantor and Borrower has no material stock
or other equity investment in any other corporation, partnership, or other
Person.

                 SECTION 5.14 -- Investment Company Status.  The Borrower is
not an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940, as amended.


                                   ARTICLE VI

                             AFFIRMATIVE COVENANTS

                 So long as any Note, or any amount owed by Borrower under any
other Basic Document, remains outstanding or unpaid or Lender has any
Commitment hereunder;

                 SECTION 6.01 -- Financial Statements.  Borrower shall furnish
to Lender:

                 (a)      within 45 days after the end of each of the first
         three quarters in each fiscal year, consolidated

          statements of operations of Borrower and its consolidated
         subsidiaries for the period from the beginning of the then-current
         fiscal year to the end of such quarterly period, and balance sheets of
         Borrower and its consolidated subsidiaries, on a consolidated basis,
         as of the end of such quarter prepared in accordance with GAAP and
         setting forth in each case in comparative form figures for the
         corresponding period in the preceding year, all in reasonable detail
         and certified by the Chief Financial Officer of Borrower, subject to
         changes resulting from year-end adjustments, and Borrower's Form 10-Q
         for such period;

                 (b)      within 90 days after the end of each fiscal year,
         consolidated statements of operations of Borrower and its consolidated
         subsidiaries, for such year, and the balance sheets of Borrower and
         its consolidated subsidiaries, on a consolidated basis, as of the end
         of such year, setting forth in each case in comparative form
         corresponding figures from the preceding annual audit, all in
         reasonable detail, and certified to Borrower by its independent
         certified public accountants and to Lender by Borrower's Chief
         Financial Officer, as presenting fairly the financial position and
         results of operations of Borrower and its
<PAGE>   18
                                     -14-
         consolidated subsidiaries and as having been prepared in accordance
         with GAAP, and Borrower's Form 10-K for such period;

                 (c)      within two Business Days after any officer of
         Borrower obtains knowledge of any Default, an Officer's Certificate
         specifying its nature, the period of its existence, and what action
         Borrower proposes to take with respect to it; and

                 (d)      promptly upon request, such other data or information
         (financial or otherwise) regarding Borrower or the Collateral as
         Lender from time to time reasonably requests.

                 SECTION 6.02 -- Inspection of Collateral and Records.
Borrower shall permit any person(s) from time to time designated in writing by
Lender, at Lender's expense (or at Borrower's expense if a Default exists at
the time), to visit and inspect any of the Collateral and Borrower's (or any
Permitted Lessee's) records with respect to the Collateral, at such times as
Lender reasonably requests, and to discuss Borrower's affairs, finances, and
accounts with Borrower's officers.  No such inspection shall

unreasonably interfere with Borrower's (or any Permitted Lessee's) operations
or maintenance.  Lender shall have no duty to make any such inspection and
shall not incur any liability or obligation by reason of not making any such
inspection.  Upon Lender's request, Borrower shall promptly notify Lender of
the maintenance operations then scheduled on the Aircraft for the six-month
period following such request.

                 SECTION 6.03 -- Corporate Existence.  Except as permitted by
section 6.04, Borrower shall maintain its corporate existence in good standing
in the state of its incorporation and in all jurisdictions where qualification
is necessary (except in any jurisdiction in which the failure to qualify would
have no materially adverse effect on its business or on its ability to carry
out its obligations under the Basic Documents to which it is (or it to become)
a party).  Borrower shall preserve and renew its rights (charter and
statutory), patents, and franchises, unless Borrower determines in good faith
that the preservation thereof is no longer necessary or desirable in the
conduct of its business and that the loss thereof will not adversely affect
Lender's rights or Borrower's business, assets, operations, condition
(financial or otherwise).

                 SECTION 6.04 -- Merger.  Borrower shall not consolidate with
or merge into any other corporation, or convey, transfer, or lease all or
substantially all of its assets as an entirety to any Person, unless:
<PAGE>   19


                                     -15-


                 (a)      the Borrower is the surviving corporation;
         or

                 (b)      the corporation formed by such consolidation or
         merger or the Person who acquires by conveyance, transfer, or lease
         all or substantially all of Borrower's assets as an entirety (the
         "Successor") (i) is a corporation organized and existing under the
         laws of the United States of America or any state or the District of
         Columbia, (ii) is a "citizen of the United States" as defined in
         section 101(16) of the Act, (iii) is an air carrier (within the

         604(b) of the Act, (iv) executes and delivers to Lender an agreement,
         in form and substance satisfactory to Lender, containing an
         assumption by the Successor of the due and punctual performance and
         observance of Borrower's obligations under the Basic Documents to
         which Borrower is then a party, and (v) makes such

         filings and recordings, including any filing or recording with the FAA
         pursuant to the Act or any filing under the UCC, as are necessary to
         evidence such consolidation, merger, conveyance, transfer, or lease
         with or to the Successor; and

                 (d)      Borrower or the Successor delivers to Lender,
         promptly upon consummation of such transaction, an Officer's
         Certificate stating that the conditions precedent set forth in clauses
         (a) and (b) have been complied with and an opinion of counsel to
         Borrower or the Successor, in form and substance satisfactory to
         Lender, stating that the agreements entered into to effect such
         consolidation, merger, conveyance, transfer, or lease and such
         assumption agreements have been duly authorized, executed, and
         delivered by the Successor and that they (and the Basic Documents so
         assumed) constitute legal, valid, and binding obligations of the
         Successor, enforceable in accordance with their terms (to the same
         extent as the Basic Documents so assumed were enforceable against
         Borrower); and that all conditions precedent which are legal in nature
         provided for in this Agreement and relating to such transactions have
         been fulfilled.

                 Upon any such consolidation, merger, conveyance, transfer, or
lease, the Successor shall succeed to, shall be substituted for, and may
exercise every right and power of Borrower under the Basic Documents to which
Borrower is a party, with the same effect as if the Successor had been named as
Borrower therein.  No such conveyance, transfer, or lease of substantially all
of Borrower's assets as an entirety shall have the effect of releasing Borrower
(or any Successor) from its liability under the Basic Documents to which it is
a party.  Nothing in this section shall

                                     -16-

permit any lease, sublease, or other arrangement for the use, operation, or
possession of the Aircraft except in compliance with the applicable provisions
of this Agreement and the Mortgage.

                 SECTION 6.05 -- Citizenship and Air Carrier Status.  Borrower
will at all times remain a "citizen of the United States" as defined in section
101(16) of the Act and an "air carrier" within the meaning of the Act.

                 SECTION 6.06 -- Compliance with ERISA.

                 (a)      Borrower will, at all times, make prompt payment of
         contributions that it is required to make to any employee benefit plan
         to which it is a party as are necessary to meet the minimum funding
         standards for such an employee benefit plan, as required by ERISA.

                 (b)      Within two Business Days after the occurrence of any
         event or circumstance, including any event which is classified as a
         "Reportable Event" under ERISA, in connection with any employee
         benefit plan to which it is a party, that might constitute grounds for
         termination of an employee benefit plan to which Borrower is a party
         by the Pension Benefit Guaranty Corporation or might result in the
         appointment of a trustee by a United States District Court under
         section 4042 of ERISA to administer such employee benefit plan;
         Borrower will provide Lender with an Officer's Certificate describing
         the event or circumstance, stating the reasons for any such action by
         the Pension Benefit Guaranty Corporation or a United States District
         Court, and specifying the action Borrower proposes to take with
         respect thereto.

                 SECTION 6.07 -- Disposition of Assets.  Borrower will not
dispose of any of its assets, other than in the ordinary course of its
business, unless it receives full, fair, and reasonable consideration for such
assets; and Borrower will not during any twelve-month period dispose of assets,
other than in the ordinary course of its business, which have an aggregate book
value in excess of $5,000,000; provided, that Borrower shall have the right to
dispose of any aircraft for at least such aircraft's book value and such sale
of an aircraft for at least book value will not be included in the calculation
of the $5,000,000 of assets sold in a twelve-month period.  The book value of
an aircraft shall be determined in accordance with GAAP.  For avoidance of
doubt, the "ordinary course" of Borrower's business generally shall include (x)
acquisitions or dispositions of marketable securities (other than acquisitions
or dispositions exceeding 5% of any class of "equity security", as defined in
the Securities Exchange Act of 1934) and (y) the disposition of parts of

discontinued aircraft, engines, or propellers not constituting part of a
program to reduce Borrower's fleet in any material respect.  Borrower will not
dispose of any Aircraft unless the Note issued in connection with such Aircraft
has been paid in full.

         Guarantor in the Basic Documents, or in any certificate or other
         document that borrower or Guarantor furnishes pursuant to the Basic
         Documents, proves to have been incorrect in any material respect when
         made;

                 (c)      Borrower fails to maintain the insurance required by
         the terms of the Mortgage;

                 (d)      the Delta Agreement is voluntarily terminated, or is
         amended to the detriment of Borrower;

                 (e)      Borrower fails to provide Lender with the Officer's
         Certificate required by section 6.01(c) or 6.06(b) within 10 days
         after any of Borrower's officers obtains notice of a Default or the
         ERISA-related event or circumstance occurs, respectively;


                 (f)      Borrower or Guarantor fails to perform any other
         material covenant or agreement in the Basic Documents, and (if
         remediable) such failure to perform continues for 30 days after
         Borrower's or Guarantor's receipt of notice of such default from
         Lender;

                 (g)      either of the Borrower or the Guarantor (1) applies
         for or consents to the appointment of, or the taking of possession by,
         a receiver, custodian, trustee, or liquidator of itself or of all or a
         majority of its property, (2) makes a general assignment for the
         benefit of its creditors, (3) commences a voluntary case under the
         federal Bankruptcy Code (as now or hereafter in effect), (4) files a
         petition seeking to take advantage (as debtor) of any other law
         relating to bankruptcy, insolvency, reorganization, winding-up, or
         composition or readjustment of debts, or (5) fails to controvert in a
         timely manner, or acquiesces in writing to, any petition filed against
         it in an involuntary case under the federal Bankruptcy Code;

                 (h)      a proceeding or case is commenced, without the
         application or consent of Borrower or Guarantor, as the case may be,

         Borrower or Guarantor totalling more than $5 million are in default
         after the expiration of any applicable grace period, if the effect of
         such default is to permit such obligations to be accelerated or
         otherwise declared to be due and payable prior to their stated
         maturity, or Borrower or Guarantor defaults in the payment when due of
         more

         than $5 million of loan, lease, or deferred purchase obligations;

                 (j)      one or more judgment(s) is/are rendered by one or

         respect to an employee benefit plan to which Borrower is a party,
         that, in the opinion of Lender, provides grounds for the commencement
         of any proceeding under Section 4042 of ERISA, or any proceeding shall
         be commenced under Section 4042 of ERISA with respect to an employee
         benefit plan to which Borrower is a party;

                 (l)      Borrower shall deny any further liability under any
         Note or under any other Basic Document or Guarantor shall deny any
         further liability under the Guarantee; or

                 (m)      Lender fails or ceases to have a perfected
         first-priority interest in an Aircraft, or a Lien (other than a
         Permitted Lien) on an Aircraft exists.

under Section 8.01(g) or (h)) exists, Lender may declare all Notes to be
immediately due and payable, whereupon (i) all Notes shall become and be
immediately due and payable without presentment, demand, protest, or other

Commitment shall terminate.  If an Event of Default under section 8.01(g) or

and the Commitment automatically shall immediately terminate, without
presentment, demand, protest, or notice of any kind, all of which Borrower
hereby waives.

                             BORROWER'S INDEMNITIES

                 SECTION 9.01 -- General Indemnity.  Borrower assumes liability
for, and agrees to indemnify each Indemnitee against, and on written demand to
pay, or to reimburse each Indemnitee for the payment of, any and all
liabilities, obligations, losses, damages, penalties, claims (including claims
involving strict liability in tort), suits, actions, costs, expenses, and
disbursements, including legal fees and expenses, of whatsoever kind and nature
(collectively, "Liabilities") imposed on, incurred by, or asserted against any
Indemnitee relating to or arising out of any Basic Document, the enforcement
against Borrower of any of the terms of the Basic Documents, or any lease or
relinquishment of possession of the Aircraft or any part thereof or any action
or inaction of Borrower or of any lessee, assignee, or transferee of Borrower
in connection therewith, the purchase of the Aircraft under the Purchase
Agreement, the ownership of the Aircraft, the acquisition, delivery,
nondelivery, acceptance, nonacceptance, rejection, registration,
deregistration, insuring, storage, manufacture, assembly, transportation,
importation, exportation, maintenance, condition, modification, testing,
repair, fitness for use, merchantability, sale, abandonment, lease, sublease,
assignment, transfer, transfer of title, possession, repossession, use,
operation, return, or other application or disposition of the Aircraft or any
component thereof, the condition upon return thereof after repossession
following the occurrence of an Event of Default or following the exercise of
remedies under the Mortgage, including latent or other defects, whether or not
discoverable, loss of or damage to any property or the environment, death or
injury of any person, and any claim for patent, trademark, copyright, or mask
work infringement and the violation or infringement by Borrower of any laws,
rules, or regulations, or (without limiting any of the foregoing) any breach by
Borrower of, noncompliance by Borrower with, or misrepresentation made or
deemed made by or on behalf of Borrower in, under, or in connection with the
Purchase Agreement or any Purchase Agreement Assignment or any warranty,
certificate, or agreement made or delivered in, under, or in connection with
the Purchase Agreement or any Purchase Agreement Assignment; provided, that
this section shall not require Borrower to pay or indemnify any Indemnitee
under this section (i) for any Liability to the extent resulting from its acts
of gross negligence or willful misconduct; (ii) for any Liability

with respect to Taxes (Borrower's duties in respect of Taxes being set forth in
section 9.02) or for any cost or expenses relating to the preparation,
execution, delivery, or enforcement of the Basic Documents (Borrower's duties
in respect of such costs and expenses being set forth in
<PAGE>   29

                                     -25-

section 9.02) or for any cost or expenses relating to the preparation,
execution, delivery, or enforcement of the Basic Documents (Borrower's duties in
respect of such costs and expenses being set forth in section 11.03); (iii) for
any Liability that such Indemnitee incurs to the extent resulting from its
breach of any of its representations, warranties, or covenants in any Basic
Document; (iv) for any Liability to the extent resulting from a claim against
such Indemnitee not related to any Aircraft, any action or inaction of Borrower
or any lessee, assignee, or transferee of Borrower, or any of the transactions
contemplated by the Basic Documents; (v) for any Liability with respect to
transfer taxes or other expenses payable with respect to the transfer of any
Note, other than a transfer after the occurrence of an Event of Default; or (vi)
for any Liability with respect to any violation or purported violation of any
law relating to usury or the charging or collecting of excess interest or
finance charges.  If any Indemnitee obtains knowledge of any claim or liability
required to be indemnified against under this section 9.01, such Indemnitee
shall promptly notify Borrower, but the failure to do so shall not relieve
Borrower from any liability that it otherwise would have to such Indemnitee
under this section.  Upon an Indemnitee's request, the defense of any Liability
for which Borrower would be required to indemnify such Indemnitee hereunder
shall be conducted by Borrower, with counsel selected by Borrower and
satisfactory to Lender.  However, if the defense of any such Liability is
conducted by Lender, Lender shall select the counsel to conduct it, but shall
consult with Borrower as to such selection; provided, that the decision as to
which counsel to select shall be and remain Lender's.  Borrower shall be
obligated under this section 9.01 irrespective of whether the Indemnitee is also
indemnified with respect to the same matter under any other Basic Document or
other document by any other Person, and the Indemnitee may proceed directly
against Borrower under this section 9.01 without first reporting to any such
rights of indemnification.  Upon the payment in full of any indemnities due and
owing under this section 9.01, Borrower shall be subrogated to any right of the
Indemnitee in respect of the matter against which indemnity has been given.
Borrower's indemnities in this section shall survive expiration or termination
of the Mortgage and payment in full of the Notes.

                 Any payment or indemnity pursuant to this section 9.01 shall
include the amount, if any, necessary to hold the Indemnitee harmless on an
after-tax basis from all

taxes required to be paid by such recipient with respect to such payment or
indemnity under laws of any federal, state, or local government or taxing
authority in the United States or by any foreign government or any political
subdivision or taxing authority thereof.  The amount of any payment or
indemnity required under this section shall be determined by the Indemnitee
reasonably and in good faith, and that determination shall be conclusive.  Upon
Borrower's request and at Borrower's expense, the

                                     -26-

Indemnitee will provide Borrower with a summary explanation of the basis for the
Indemnitee's computations.

                 SECTION 9.02 -- Taxes.

                 (a)      Indemnity.  All payments by Borrower under this
Agreement and under any Note shall be free of withholdings of any nature
whatsoever (and at the time that Borrower is required to make any payment upon
which any withholding is required, Borrower shall pay an additional amount such
that the net amount actually received by the person entitled to receive such a
payment will, after such withholding, equal the full amount of the payment then
due) and shall be free of expense to each Indemnitee for collection or other
charges.  In addition, except as provided in section 9.02(b), Borrower agrees
to indemnify each Indemnitee on a net after-tax basis against, and on written
demand to pay or reimburse each Indemnitee for the payment of, and shall
promptly pay and discharge when due except to the extent duly contested, any
and all Taxes imposed upon or asserted against any Indemnitee, any Aircraft or
any part thereof or interest therein, any Basic Document, any lease of any
Aircraft or any part thereof, or otherwise upon or with respect to or measured

request of Borrower, purchase, acquisition, acceptance, nonacceptance,
rejection, delivery, nondelivery, transport, insuring, ownership, registration,
deregistration, assembly, possession, repossession, operation, use, condition,
maintenance, modification, repair, fitness for use, merchantability, testing,
return, abandonment, storage, manufacture, leasing, subleasing, importation,
exportation, sale, assignment, transfer, transfer of title, or other
application or disposition of, or the imposition of any Lien (other than a
Permitted Lien) or the incurrence of any liability to refund or pay over any
amount as a result of any Lien other than a Permitted Lien) on any Aircraft or
any part thereof or interest therein, (ii) any amount paid or payable by
Borrower or Finex Bank under the Basic Documents or the receipts or earnings
arising from or received with respect to any Aircraft or any part thereof

or interest therein, (iii) any Aircraft or any part thereof or interest
therein, (iv) any of the Basic Documents and any other documents contemplated
thereby or the execution, sale, delivery, acquisition, or filing of the Basic
Documents, (v) any rentals or other payments made or received by Borrower under
any lease or sublease of any Aircraft or any part thereof or (vi) otherwise
with respect to or in connection with the transactions effected under the Basic
Documents.  The term "Taxes" shall mean any and all fees, taxes, levies,
imposts, duties, charges, assessments, or withholdings of any nature
whatsoever, now or hereafter imposed, assessed or asserted by any federal,
state, local or foreign government or taxing authority
<PAGE>   31

                                     -27-

together with any and all penalties, fines, additions to tax, and interest
thereon or computed by reference thereto.

                 (b)      Exclusions from Indemnity.  The provisions of section
9.02(a) shall not apply to:

                          (i)     Taxes (other than sales, use or rental taxes
         imposed as a result of any Indemnitee's interest in any Equipment
         Portion or the Basic Documents) which are United States federal net
         income taxes;

                          (ii)    Taxes (other than sales, use or rental taxes
         imposed as a result of any Indemnitee's interest in any Equipment
         Portion or the Basic Documents) which are net income, capital, net
         worth, franchise, or similar conduct of business taxes which are
         imposed on an Indemnitee by the state or local government or taxing
         authority in which such Indemnitee conducts any business other than
         the transactions contemplated in the Basic Documents;

                          (iii)   Taxes (other than sales, use or rental taxes
         imposed as a result of any Indemnitee's interest in any Equipment
         Portion of the Basic Documents) which are imposed by any foreign
         government or taxing authority upon an Indemnitee if such Indemnitee
         is otherwise subject to such taxes in such jurisdiction as a result of
         activities or transactions unrelated to those contemplated by the
         Basic Documents;

                          (iv)    any Tax imposed on the Indemnitee as a result
         of a transfer or other disposition, by such Indemnitee or any of its
         predecessors in interest, of any interest in the Aircraft or any Basic
         Document, unless such transfer or disposition occurs after the
         occurrence of an Event of Default or at the request of Borrower;

                          (v)     Taxes imposed on an Indemnitee as a direct
         and primary result of such Indemnitee's gross negligence or willful
         misconduct;

                          (vi)    any Tax based on or measured by the value of
         such Indemnitee's interest in any Basic Document (except for any such
         Tax (1) imposed without regard to the existence or extent of the
         Indemnitee's presence or activities, or the presence of a Note, in the
         jurisdiction imposing such Tax or (2) imposed solely as a result of
         the Indemnitee's execution of, or enforcement of rights under, the
         Basic Documents); or

                          (vii)   any Tax in the nature of a penalty, an
         addition to tax, interest, or fine resulting from the negligence or
         misconduct of the
<PAGE>   32
                                     -28-

         Indemnitee in connection with the preparation or filing of (or
         failure to prepare or file) tax returns, or the payment
         of or failure to pay its taxes, but in each case not if an any way
         attributable to reports and returns for which Borrower is responsible
         pursuant to section 9.02(e) Borrower's failure to provide to any
         Indemnitee any information necessary for the preparation or filing of
         such returns or the conduct of such proceedings or otherwise to
         perform its duties and responsibilities pursuant to the Basic
         Documents.

                 (c)      Certain Tax Payments.  Notwithstanding anything to
the contrary in this section 9.02, if an Indemnitee pays or becomes liable for
any Tax that Borrower has agreed to pay under this section 9.02, Borrower shall
pay to such Indemnitee such amount or from time to time such amounts as, after
subtraction of all Taxes required to be paid by such Indemnitee in respect of
the receipt of such amounts from Borrower under this Section 9.02 and taking
into account any tax benefit or detriment actually realized (or to be realized)
by such Indemnitee as a result of such Indemnitee's receipt of such payment, is
equal to the sum of such Taxes payable by such Indemnitee from time to time.
All Taxes shall be paid when due and payable and all amounts payable as
indemnities pursuant to section 9.02(a) shall be payable in accordance with
this section 9.02(c), to the extent not theretofore paid, on written demand by
the appropriate Indemnitee.  The amount of any payment or indemnity required
under this section shall be determined by the Indemnitee reasonably and in good
faith, and that determination shall be conclusive.  Upon Borrower's request and
at Borrower's expense, the


Indemnitee will provide Borrower with a summary explanation of the basis for
the Indemnitee's computations.

                 (d)      Refund of Withholding Taxes to Borrower.  If,
pursuant to the first sentence of section 9.02(a) hereof, Borrower has withheld
any amount from any payment in respect of any withholding tax with respect to a
Tax not indemnifiable by Borrower pursuant to section 9.02(a) and Borrower has
paid over such withheld amount to the proper taxing authority for the account
of such Indemnitee, Borrower shall notify such Indemnitee of the amount of such
withholding and provide to such Indemnitee a receipt or other documentation
evidencing payment of the withheld amount.  Upon receipt of the notice
described in the preceding sentence, such Indemnitee shall promptly repay to
Borrower, the amount withheld together with interest thereon from the date of
receipt of the notice to the date of repayment at the then current rate set by
the taxing jurisdiction for overpayments of such Tax.

                 (e)      Reports.  Borrower will, at its own expense, duly
prepare and file all required reports and returns
<PAGE>   33

                                     -29-

respecting all Taxes for which Borrower is responsible pursuant to section
9.02(a) to the extent it is required by law to do so.  With regard to any
reports and returns required to be filed by any Indemnitee covering any Taxes
for which Borrower is responsible pursuant to section 9.02(a), Borrower shall
upon request furnish such Indemnitee with such information and records (to the
extent Borrower has possession thereof or may obtain possession thereof upon
Borrower's exercise of reasonable efforts) relating thereto as is reasonably
required by Indemnitee to make such filing and funds in the amount required to
be submitted as reflected on such report or return.  Borrower shall hold each
Indemnitee harmless from and against any liabilities, obligations, losses,
damages, penalties, claims, actions, suits and reasonable costs arising out of
any insufficiency or inaccuracy contained in any report or return (i) prepared
and filed by Borrower (but only to the extent not attributable to the
information provided to Borrower by such Indemnitee) or (ii) prepared and filed
by any Indemnitee (but only to the extent attributable to information provided
to such Indemnitee by Borrower). If, as a result of an audit, an Indemnitee
reasonably requests additional information, Borrower shall make available such
other information and records as it maintains in the ordinary course of
business.

                        ILLEGALITY AND YIELD PROTECTION

                 SECTION 10.01 -- Illegality and Increased Costs.

                 (a)      Illegality.  If, after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change therein,
or any change in the interpretation, administration or enforcement thereof by
any governmental authority, central bank or other comparable authority or
compliance by Lender with any request, guideline or directive (whether or not
having the force of law) of any governmental authority, central bank or other
comparable authority shall, in the reasonable determination of Lender, make it
unlawful or impossible for Lender to issue, maintain or fund any Note or to
perform any obligation under this Agreement or any other Basic Document, Lender
shall so notify Borrower and, subject to the provision of section 10.01(c)
hereof, on the next Interest Payment Date (or such earlier date as Lender shall
specify in such notice after which it may not lawfully continue to maintain
such Note or its obligations under this Agreement), Borrower shall prepay such
Note, plus accrued interest thereon and the remaining Commitment, if any, of
Lender shall terminate.

                                     -30-

                 (b)      Increased Cost.  If, after the date of this
Agreement, the adoption of any applicable law, rule or regulation, or any
change therein, or any change in the interpretation, administration or
enforcement thereof by any governmental authority, central bank or other
comparable authority or compliance by Lender with any request, guideline or
directive (whether or not having the force of law, but with respect to which
Lender customarily complies and which is applied by Lender to all other loans
of similar type) of any governmental authority, central bank or other
comparable authority shall, in the reasonable determination of Lender:

                 (i)      impose, modify or deem applicable any capital
         adequacy, reserve, special deposit or similar requirement (including,
         without limitation, a request or requirement which affects the manner
         in which Lender allocates capital resources to its commitments,
         including its obligations under this Agreement); or

                 (ii)     impose on Lender any other condition or requirement
with respect to its issuing, maintaining


                 or funding any Note or its obligations under this Agreement;

         and the result of any of the foregoing is to:

                 (x)      increase the funding cost to Lender of making,
         maintaining or funding or performing its obligations under this
         Agreement; or

                 (y)      reduce the amount of any payment (whether of
         principal, interest or otherwise) received or receivable by Lender
         hereunder; or

                 (z)      reduce the rate of return to be earned by Lender with
respect to any Note;

Borrower shall pay to Lender within 15 days after demand such additional amount
or amounts as will compensate Lender for such increased cost or reduction.  A
certificate of Lender as to any such additional amount or amounts, in the
absence of manifest error, shall be final and conclusive.  In determining such
amount, Lender shall use any reasonable averaging and attribution methods.
Lender will promptly notify Borrower after Lender obtains knowledge of the
occurrence of an event which would entitle Lender to compensation hereunder.

                 (c)      Change of Lending Office, Etc.

                 (a)      If an event occurs which makes the provisions of
         section 10.01(a) or 10.01(b) applicable, Lender will, if requested by
         Borrower, use reasonable
<PAGE>   35
                                     -31-

         efforts to transfer the affected Notes and its obligations hereunder
         with respect to such Notes to another branch or office of Lender to
         which such event would not be applicable, provided that such transfer
         would not, in the sole judgment of Lender, be disadvantageous to
         Lender or contrary to Lender's policies.

                 (b)      Lender may at any time and from time to time transfer
         any Note or its obligations under this Agreement with respect to such
         Note to another branch or office of Lender and shall give notice of
         any such transfer to Borrower.  Except in the case of a transfer made
         at the request of Borrower, no such trasnfer shall make operable the
         provisions of section 10.01(a) or entitle Lender to make a claim
         under section 10.01(b) if the operability of such clause or such
         claim results solely from such transfer and not

         from subsequent change of the type referred to therein.

                 SECTION 10.02 -- Funding Losses.  Borrower shall pay to
Lender, upon request, such amount or amounts as Lender determines are necessary
to compensate it for any loss, cost or expense incurred by it as a result of
(a) any payment or prepayment of any Note on a date other than the last day of
an Interest Period for such Note or (b) a Note for any reason not being
purchased on the date therefor determined in accordance with the applicable
provisions of this Agreement.  Such amount payable by Borrower shall not
include any loss, cost or expense attributable to any date more than 180 days
after the date of such payment, prepayment or failure to purchase any Note.  A
certificate of Lender as to the amount of such loss, cost or expense shall be
final and conclusive in the absence of manifest error.


                                   ARTICLE XI

                                 MISCELLANEOUS

                 SECTION 11.01 -- No Waivers; Cumulative Remedies.  No failure
or delay in exercising any power or right under any Basic Document shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right or power preclude other or further exercise thereof or the exercise
of any other right or power under any Basic Document.  No notice to or demand
on any party in any case shall, of itself, entitle such party to any other or
further notice or demand in similar or other circumstances.

                 SECTION 11.02 -- Notices.  All communications and notices
provided for under this Agreement shall be in writing (including telex,
telegraph, and telecopy), shall
<PAGE>   36

                                     -32-

be in English, and shall be mailed by certified mail (return receipt requested)
or otherwise delivered to the parties at the addresses set forth by their
signatures hereto, or, as to teach party, at such other address as it designates
by notice to each other party.  Each such notice shall be effective upon
delivery.

other Basic Documents (except for such amendments, waivers, or consents
initiated by Lender); and (iv) all fees and expenses (including legal fees and
expenses) of Lender in connection with the actual or proposed enforcement of any
Basic Document against Borrower during the existence of any Default.  The "legal
fees and expenses" of Lender referred to in clauses (iii) and (iv) may include
those of Lender's in-house counsel, provided that such legal fees and expenses
do not result from efforts which are duplicative of those of special counsel to
Lender.

                 SECTION 11.04 -- Amendments.  Any provision of the Basic
Documents, other than the Purchase Agreement, the Guarantee, or the Finex
Agreement, may be amended, terminated, waived, or otherwise modified only in

without Lender's prior written consent.  Lender may at any time with the
Borrower's consent (which consent shall not be unreasonably withheld) sell,

in part.

Agreement and the other Basic Documents to which it is a party; and

                 (c)      neither it nor anyone authorized to act on its behalf

of 1933, as amended, or any state securities law; provided, that the foregoing
shall not be deemed to extend to any such offer, sale, or solicitation by or on

THIS AGREEMENT, THE MORTGAGE, THE NOTES OR THE RELATIONSHIP ESTABLISHED
HEREUNDER.

                 SECTION 11.09 -- Headings.  Article and section headings used
in this Agreement are for convenience only and not a substantive part of this
Agreement.

                 SECTION 11.10 -- Execution in Counterparts.  This Agreement
may be executed in separate counterparts.

                 SECTION 11.11 -- Survival of Representations and Warranties.
All representations and warranties contained in this Agreement or made in
writing in connection with this Agreement shall survive the execution and
delivery of this Agreement and the Mortgage.

<PAGE>   38
                                     -34-

under the Finex Agreement by Lender as Finex Interest Payments or interest
thereon, or as indemnification

payments for amounts which Lender has previously been indemnified by Borrower,
shall be forwarded by Lender to Borrower at First American Bank of Georgia N.A.,
2000 RiverEdge Parkway, Atlanta, Georgia 30328, Account: Atlantic Southeast
Airlines, Inc. (account #5100130970).  Lender shall use its good faith efforts
to forward any such payments to Borrower on the Business Day following their
receipt by Lender.  At the cost and expense of Borrower, Lender shall use its
good faith efforts to take such action with respect to the Finex Agreement as
Borrower shall reasonably request, provided that Lender shall not be required to
take any action which adversely affects its interests under the Finex
Agreement.  However, all risks associated with the Finex Program are Borrower's
and Lender shall have no responsibility for any Finex Interest Payments not
actually received by Lender from Finex Bank.  So long as no Event of Default
exists, Lender shall not amend the Finex Agreement without the consent of the
Borrower, such consent not to be unreasonably withheld.
