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 to 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 between Delta Air Lines, Inc. and Borrower 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 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 ASA Investments, Inc. 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





                                       12
<PAGE>   17

         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 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 is 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





                                       13
<PAGE>   18

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, etc. 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:

                 (a) the corporation formed by such consolidation or the Person
         who acquires by conveyance, transfer, or lease all or Substantially
         all of Borrower's assets as an entirety (the "Successor") or, in
         the case of a merger, Borrower (as the surviving corporation),
         (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, and (iii) is an air carrier (within the meaning of section
         101(3) of the Act) certificated under section 604(b) of the Act; and,
         in the case of such a consolidation, conveyance, transfer or lease,
         the Successor: (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;

                 (b) immediately after giving effect to such transaction, (i)
         no Default exists and (ii) Borrower's or the Successor's, as the case
         may be, business, assets, operations, condition (financial or
         otherwise), and financial and other ability to perform its obligations
         under the Basic Documents will not be adversely affected by such
         transaction in any material respect; and

                 (c) 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 clause (a) have
         been complied with and an opinion of counsel for Borrower or for 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 (or in
         the case of a merger, by Borrower) and that they (and the Basic
         Documents so assumed) constitute legal, valid, and binding obligations
         of the Successor (or in the case of a merger, of Borrower),
         enforceable in accordance with their terms (to the same extent as the
         Basic Documents so assumed were enforceable against Borrower
         immediately prior to such transaction); and that all conditions
         precedent which are





                                       14
<PAGE>   19

         legal in nature provided for in this Agreement and relating to such
         transaction have been fulfilled.

                 Upon any such consolidation, 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 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 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.

                 Borrower shall not become a subsidiary of a holding company
without Lender's prior written consent.

                 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





                                       15
<PAGE>   20

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.

                 SECTION 6.08 -- Performance of Delta Agreement.  Borrower
shall faithfully perform all obligations it has under the Delta Agreement.

                 SECTION 6.09 -- Financial Covenant. Borrower shall not permit
at any time on a consolidated basis (consolidating Borrower and its
subsidiaries) its ratio of Indebtedness to Tangible Net Worth to exceed 3.25 to
1.  "Tangible Net Worth" shall mean Book Net Worth minus (a) the amount, if
any, of Borrower's and its subsidiaries' assets which would be treated as
intangibles under generally accepted accounting principles; (b) any write-up in
the book value of any fixed asset resulting from a revaluation thereof; and (c)
the amount, if any, at which shares of stock of Borrower appear on the asset
side of the Borrower's balance sheet.  "Book Net Worth" shall mean the book
value of Borrower's and its subsidiaries' total assets located in the United
States of America (exclusive of any indebtedness owed to Borrower or its
subsidiaries by any affiliate of Borrower) minus Borrower's and its
subsidiaries' total liabilities. For avoidance of doubt, the phrase "total
assets located in the United States of America" shall include marketable
securities and commercial paper issued by a foreign entity but held in the
United States of America by Borrower or any of its subsidiaries.

         continues unstayed and in effect, for a period of 60 days; or an order
         for relief against Borrower is entered in an involuntary case under
         the federal Bankruptcy Code;

                 (i) loan, lease, or deferred purchase obligations of Borrower
         totaling more than $1 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 defaults
         in the payment when due of more than $l million of loan, lease, or
         deferred purchase obligations;

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

         benefit plan to which Borrower is a party under section 4041(c) or (e)
         of ERISA, or any fact or circumstance shall occur with 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; or

                 (l) Borrower shall deny any further liability under any Note

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
notice of any kind, all of which Borrower hereby waives, (ii) the Interest
Supplement for any partial Interest Period will become immediately due and
payable, and (iii) the Commitment shall terminate. If an Event of Default under

without presentment, demand, protest, or notice of any kind, all of which
Borrower hereby waives.

<PAGE>   25


                 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 such
Indemnitee's acts of gross negligence or willful misconduct; (ii) for any Taxes
(Borrower's duties in respect of Taxes being set forth in section 9.02) or for
any cost or expense 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 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





                                       21
<PAGE>   26

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

                 SECTION 9.02 -- Taxes.

                 (a) Indemnity. Except as provided in section 9.02(b), Borrower
agrees to indemnify each Indemnitee against, and on written demand to pay or
reimburse each Indemnitee for the payment of, 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
the rentals received under such a lease, by any federal, state, or local
government or other taxing authority in the United States (including any
territory or possession of the United States) or by any foreign government or
any political subdivision or taxing authority thereof where any part of an
Aircraft is located, used, or registered ( "Taxing Authorities") upon or with
respect to (i) the construction, mortgaging, financing, refinancing by or at
the 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,





                                       22

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,
or (v) 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, 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) any Tax based on, or measured by, net income, capital,
         franchise, or net worth (other than sales taxes), including related
         surcharges and withholding taxes; provided, that the provisions of
         this clause (b)(i) shall not apply to any Taxes imposed in respect of
         the receipt or accrual of any indemnity payment made or payable
         pursuant to this section 9.02;

                 (ii) any Tax based on or measured by the value of such
         Indemnitee's interest in any Basic Document, except to the extent
         imposed without regard to the presence of the Indemnitee, or any Note,
         in the jurisdiction of the Taxing Authority imposing that Tax;

                 (iii) 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

                 (iv) any Tax in the nature of a penalty, an addition to tax,
         interest, or fines resulting from the negligence or misconduct of the
         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 in any way attributable to
         Borrower's failure to notify such Indemnitee of its obligations to
         prepare and file its returns in respect of Taxes indemnified pursuant
         to this section 9.02 or to provide 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.

<PAGE>   28


                 (c) Calculation of General Tax Indemnity Payments. Any payment
which Borrower is required to make to or for the account of any Indemnitee with
respect to any Tax which is subject to indemnification under this section 9.02
shall be made on a net basis, taking into account offsetting credits or
deductions available to such Indemnitee as a result of the payment of such Tax,
and shall include the amount necessary to hold such Indemnitee harmless on an
after-tax basis from the net amount of all Taxes required to be paid by such
Indemnitee as the result of such payment (including any Taxes imposed on such
indemnity payment) pursuant to the laws of any Taxing Authority. 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) Records. If Borrower shall timely file any report, return,
or statement required to be filed with respect to any Tax which is subject to
indemnification under this section 9.02, except for any such report, return, or
statement which an Indemnitee has notified Borrower that it intends to file.
Borrower shall file such report, return, or statement and send a copy to Lender
and each Indemnitee affected by such report, return, or statement. Each
Indemnitee shall promptly forward to Borrower any notice, bill, or advice
received by it concerning any Tax.


                                   ARTICLE X

                                YIELD PROTECTION

                 SECTION 10.01 -- Additional Costs.

                 (a) Borrower shall pay directly to Lender from time to time
such amounts as are necessary to compensate Lender, on an after-tax basis, for
any costs which are attributable to its purchase of or obligation to purchase
any Note hereunder, or any reduction in any amount receivable by Lender in
respect of such Notes (excluding payments under the Finex Agreement), resulting
from any Regulatory Change which imposes or modifies any reserve, special
deposit, minimum capital, capital ratio, or similar requirements relating to
any extensions of credit or other assets of or any deposits with or other
liabilities of Lender, or the manner in which Lender funds (or allocates funds,
on its books, for) its investments in any of the Notes.

                 (b) Determinations and allocations for purposes of this
section 10.01 of the effect of any Regulatory Change pursuant to section
10.01(a) on Lender's costs or rate of return of maintaining or its obligations
to purchase any Note, or on amounts receivable by it in respect of any Note,
and of amounts required to compensate Lender under this section 10.01, shall be
made by Lender reasonably and in good faith and shall be conclusive. Upon
Borrower's request





                                       24
<PAGE>   29

and at Borrower's expense, Lender will provide Borrower with a summary
explanation of the basis for Lender's computations.

                 SECTION 10.02 -- Breakage Costs.  Borrower shall pay to
Lender, upon Lender's request, such amount as is sufficient, in Lender's
opinion, to compensate it for any loss, cost, or expense which is attributable
to:

                 (a) any payment, purchase, or conversion of any Note for any
reason (including the acceleration of the maturity of the Notes pursuant to
section 8.02 and the mandatory purchase of the Note pursuant to section 4.04)
on a date other than an Interest Payment Date; or

                 (b) any failure by Vendor for any reason (including the
failure of any of the conditions precedent specified in article VII to be
satisfied) to endorse and deliver any Note to Finex Bank on the Purchase Date
specified in the relevant notice to Lender given pursuant to section 2.02.
Such amount payable by Borrower (x) shall not include losses, costs, or
expenses attributable to any date more than 180 days after the date of such
payment, purchase, or conversion or such Purchase Date, and (y) shall be
determined by Lender reasonably and in good faith, which determination shall be
conclusive. Upon Borrower's request and at Borrower's expense, Lender will
provide Borrower with a summary explanation of the basis for Lender's
computations.


                                   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 thereto, 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 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 each party, at such
other address as it designates by notice to each other party. Each such notice
shall be effective upon delivery.

                 SECTION 11.03 -- Transaction Expenses. Borrower will pay on
demand all out-of-pocket expenses in connection with the preparation,
execution, delivery, administration, and enforcement of the Basic Documents, or
in connection with any scheduled closing





                                       25
<PAGE>   30

that is postponed or cancelled, including (i) all fees and expenses of (x)
Trotter Smith & Jacobs, special counsel to Lender, (y) Castro, Barros, Sobral e
Xavier, special Brazilian counsel, and (z) Crowe & Dunlevy, special FAA
counsel; (ii) all FAA and UCC filing and lien search fees; (iii) all fees and
expenses (including legal fees and expenses) of Lender in connection with
actual or proposed amendments, waivers, or consents to or under this Agreement
or the 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.

                 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
writing by Borrower and Lender.

                 SECTION 11.05 -- Successors and Assigns. This Agreement shall
bind and benefit Lender and Borrower and their successors and assigns, except
that Borrower may not assign or transfer its rights under this Agreement
without Lender's prior written consent. Lender may at any time with the
Borrower's consent (which consent shall not be unreasonably withheld) sell,
assign, grant participation(s) in, or otherwise transfer any Note and Lender's
rights (including the right to receive Interest Supplements) relating to such
Note, in whole or in part.

                 SECTION 11.06 -- Lender's Representations and Warranties.
Lender represents and warrants that:

                 (a) it is a national banking association duly organized,
validly existing, and in good standing under the laws of the United States, and
has all corporate power, authority, and legal right under the laws of the
United States to execute, deliver, and carry out the terms of each of the Basic
Documents to which it is a party;

                 (b) it has duly authorized, executed, and delivered this
Agreement and the other Basic Documents to which it is a party; and

                 (c) neither it nor anyone authorized to act on its behalf has
directly or indirectly offered any beneficial interest in the Notes for sale
to, or solicited any offer to acquire any such interest in the Notes from, any
Person in such a manner as to require any of the Notes to be registered under
the Securities Act of 1933, as amended, or any state securities law; provided,
that the foregoing shall not be deemed to extend any such offer, sale, or
solicitation by or on behalf of Borrower or any other Person.

                 SECTION 11.07 -- Governing Law. This Agreement shall be
governed by the laws of Georgia.

<PAGE>   31


                 SECTION 11.08 -- Headings. Article and section headings used
in this Agreement are for convenience only and are not a substantive part of
this Agreement.

                 SECTION 11.09 -- Execution in Counterparts. This Agreement may
be executed in separate counterparts.

                 SECTION 11.10 -- 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.

                 SECTION 11.11 -- Severability. If any part of any provision
contained in this Agreement, or any document contemplated hereby, is or becomes
invalid or unenforceable under applicable law, that part shall be ineffective
to the extent of such invalidity only, without in any way affecting the
remaining parts of that provision or the remaining provisions.

                 SECTION 11.12 -- Finex Agreement. So long as no Default
exists, Lender shall forward any payments that it receives under the Finex
Agreement as Finex Interest Payments, or interest thereon, or as
indemnification or reimbursement under the Finex Agreement and not relating to
any loss or expense suffered 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; provided
that a reduction in the amount of Finex Interest Payments resulting from the
guarantee of such Finex Interest Payments by Finex Bank shall not be considered
an action adversely affecting Lender's interest; provided , further, that any
bank having offices in New York City and in Brazil, and authorized to act as a
Finex agent bank under the Finex Program, shall be presumed to be acceptable to
Lender as to identity. 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 Default
exists, Lender shall not enter into any amendment of the Finex Agreement
without Borrower's consent, such consent not to be unreasonably withheld.
