Trustee and (ix) the expenses of the "roadshow" and any other meetings with
prospective investors in the Securities.

          (k) In connection with the offering, until the Initial Purchaser
shall have notified the Guarantors and the Company of the completion of the
resale of the Securities, neither the Company, any Guarantor nor any of their
affiliates has bid for or purchased or will bid for or

                                                                            10

purchase, either alone or with one or more other persons, for any account in
which they or any of their affiliates have a beneficial interest in any
Securities, and neither they nor any of their affiliates will make bids or
purchases for the purpose of creating actual, or apparent, active trading in,
or of raising the price of, the Securities, in either case in violation of
Regulation M under the Exchange Act.

          (l) Between the date of this Agreement and the Closing Date, none of
the Guarantors or the Company will without the Initial Purchaser's prior
written consent offer, sell, or enter into any agreement to sell, any public
debt securities registered under the Securities Act or any debt securities
which may be resold in a transaction exempt from the registration requirements
of the Securities Act in reliance on Rule 144A thereunder and which are
marketed through the use of a disclosure document containing substantially the
same information as a prospectus for similar debt securities registered under
the Securities Act (other than the Securities).

          (m) Not to solicit any offer to buy or offer or sell the Securities
by means of any form of general solicitation or general advertising (as those
terms are used in Regulation D under the Securities Act) or in any manner
involving a public offering within the meaning of Section 4(2) of the
Securities Act.

          (n) If requested by the Initial Purchaser, to use its reasonable
efforts to permit the Securities to be designated PORTAL securities in
accordance with the rules and regulations adopted by the National Association
of Securities Dealers, Inc. relating to trading in the PORTAL Market.

          (o) None of the Company, the Guarantors, their Affiliates or any
person acting on its or their behalf (other than the Initial Purchaser) will
engage in any directed selling efforts (as that term is defined in Regulation
S) with respect to the Securities, and the Company, each of the Guarantors and
their Affiliates and each person acting on its or their behalf (other than the
Initial Purchaser) will comply with the offering restrictions of Regulation S.

          (p) Neither the Company, any Guarantor nor any Affiliate will sell,
offer for sale or solicit offers to buy or otherwise negotiate in respect of
any security (as defined in the Securities Act) which could be integrated with
the sale of the Securities in a manner which would require the registration
under the Securities Act.

     6.   Offering of Securities; Restrictions on Transfer.

          (a) The Initial Purchaser represents and warrants that it is a
qualified institutional buyer as defined in Rule 144A under the Securities Act
(a "QIB"). The Initial Purchaser agrees with the Company that (i) it has not
and will not solicit offers for, and has not offered or sold and will not
offer or sell, such Securities by any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Securities Act)
or in any manner involving a public offering within the meaning of Section
4(2) of the Securities Act and (ii) it has and will solicit offers for such
Securities only from, and has offered and will offer such Securities only to,
persons that it reasonably believes to be (A) in the case of offers inside the
United States, QIBs and (B) in the case of offers outside the United States,
to persons other than U.S. persons ("foreign purchasers," which term shall
include dealers or other professional fiduciaries in the United States acting
on a discretionary basis for foreign beneficial owners (other

                                                                            11

than an estate or trust)) that, in each case, in purchasing such Securities
are deemed to have represented and agreed as provided in the Memorandum under
the caption "Transfer Restrictions."

          (b) The Initial Purchaser represents, warrants, and agrees with
respect to offers and sales outside the United States that:

          (i) it understands that no action has been or will be taken in any
     jurisdiction by any Guarantor or the Company that would permit a public
     offering of the Securities, or possession or distribution of the
     Memorandum or any other offering or publicity material relating to the
     Securities, in any country or jurisdiction where action for that purpose
     is required;

          (ii) such Initial Purchaser will comply with all applicable laws and
     regulations in each jurisdiction in which it acquires, offers, sells or
     delivers Securities or has in its possession or distributes the
     Memorandum or any such other material, in all cases at its own expense;

          (iii) the Securities have not been and will not be registered under
     the Securities Act and may not be offered or sold within the United
     States or to, or for the account or benefit of, U.S. persons except in
     accordance with Regulation S or pursuant to an exemption from the
     registration requirements of the Securities Act;

          (iv) the Initial Purchaser has offered the Securities and will offer
     and sell the Securities (A) as part of their distribution at any time and
     (B) otherwise until 40 days after the later of the commencement of the
     offering of the Securities and the Closing Date, only in accordance with
     Rule 903 of Regulation S or another exemption from the registration
     requirements of the Securities Act. Accordingly, neither the Initial
     Purchaser, its Affiliates nor any persons acting on its or their behalf
     have engaged or will engage in any directed selling efforts (within the
     meaning of Regulation S) with respect to the Securities, and the Initial
     Purchaser, its Affiliates and any such persons have complied and will
     comply with the offering restrictions requirements of Regulation S;

          (v) the Initial Purchaser represents that it has (i) not offered or
     sold, and will not offer or sell, in the United Kingdom, by means of any
     document, any Securities other than to persons whose ordinary business it
     is to buy or sell shares or debentures, whether as principal or as agent
     (except in circumstances which do not constitute an offer to the public
     within the meaning of the Companies Act 1989 of Great Britain); (ii)
     complied and will comply with all applicable provisions of the Financial
     Services Act 1986 of the United Kingdom with respect to anything done by
     it in relation to the Securities in, from or otherwise involving the
     United Kingdom; and (iii) only issued or passed on and will only issue or
     pass on in the United Kingdom any document received by it in connection
     with the issue of the Securities to a person who is of a kind described
     in Article 9(3) of the Financial Services Act 1986 (Investment
     Advertisements) (Exemptions) Order 1996 or is a person to whom the
     document may otherwise lawfully be issued or passed on;

                                                                            12



          (vi) the Initial Purchaser understands that the Securities have not
     been and will not be registered under the Securities and Exchange Law of
     Japan, and represents that it has not offered or sold, and agrees that it
     will not offer or sell, any Securities, directly or indirectly in Japan
     or to any resident of Japan except (A) pursuant to an exemption from the
     registration requirements of the Securities and Exchange Law of Japan and
     (B) in compliance with any other applicable requirements of Japanese law;
     and

          (vii) the Initial Purchaser agrees that, at or prior to confirmation
     of sales of the Securities, it will have sent to each distributor, dealer
     or person receiving a selling concession, fee or other remuneration that
     purchases Securities from it during the restricted period a confirmation
     or notice to substantially the following effect:

          "The Securities covered hereby have not been registered under the
          U.S. Securities Act of 1933 (the "Securities Act") and may not be
          offered and sold within the United States or to, or for the account
          or benefit of, U.S. persons (i) as part of their distribution at any
          time or (ii) otherwise until 40 days after the later of the
          commencement of the offering and the closing date, except in either
          case in accordance with Regulation S (or Rule 144A if available)
          under the Securities Act. Terms used above have the meanings given
          to them by Regulation S."

Terms used in this Section 6 have the meaning given to them by Regulation S of
the Securities Act.

     7.   Indemnification and Contribution.

          (a) Each of the Company and each Guarantor, jointly and severally,
agrees to indemnify and hold harmless the Initial Purchaser, and each person,
if any, who controls the Initial Purchaser within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, or is
under common control with, or is controlled by, the Initial Purchaser, from
and against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred by the
Initial Purchaser or any such controlling of affiliated person in connection
with defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Memorandum (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact necessary to make the statements
therein in light of the circumstances under which they were made not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to the Initial Purchaser furnished to
any Guarantor or the Company in writing by the Initial Purchaser expressly for
use therein.

          (b) The Initial Purchaser agrees to indemnify and hold harmless each
Guarantor and the Company, their directors, their officers and each person, if
any, who controls the Company or any Guarantor within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act to the same
extent as the foregoing indemnity from each Guarantor and the Company to the
Initial Purchaser, but only with reference to information relating to the
Initial Purchaser furnished to any Guarantor or


<PAGE>


                                                                            13


the Company in writing by the Initial Purchaser expressly for use in the
Memorandum or any amendments or supplements thereto.

          (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to either paragraph (a) or (b) above, such
person (the "indemnified party") shall promptly notify the person against whom
such indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain
counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnifying party may designate in such
proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such indemnified party unless (i) the indemnifying
party and the indemnified party shall have mutually agreed to the retention of
such counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified
party and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all such indemnified parties and that all such fees and expenses
shall be reimbursed as they are incurred. Such firm shall be designated in
writing by the Initial Purchaser, in the case of parties indemnified pursuant
to paragraph (a) above, and by the Guarantors and the Company in the case of
parties indemnified pursuant to paragraph (b) above. The indemnifying party
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse
the indemnified party for fees and expenses f counsel as contemplated by the
second and third sentences of this paragraph, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in
respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party
from all liability on claims that are the subject matter of such proceeding.

          (d) To the extent the indemnification provided for in paragraph (a)
or (b) of this Section 7 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then
each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable
by such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Guarantors and the Company, on the one hand, and the
Initial Purchaser, on the other hand, from the offering of such Securities or
(ii) if the allocation



<PAGE>


                                                                            14

provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Guarantors
and the Company on the one hand and the Initial Purchaser on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Guarantors and the
Company on the one hand and the Initial Purchaser on the other hand in
connection with the offering of such Securities shall be deemed to be in the
same respective proportions as the net proceeds from the offering of such
Securities (before deducting expenses) received by the Guarantors and the
Company and the total discounts and commissions received by the Initial
Purchaser in respect thereof bear to the aggregate offering price of such
Securities. The relative fault of the Guarantors and the Company on the one
hand and of the Initial Purchaser on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by any Guarantor or the Company
or by the Initial Purcaser and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or
omission.

          (e) The Guarantors, the Company and the Initial Purchaser agree that
it would not be just or equitable if contribution pursuant to this Section 7
were determined by pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in
paragraph (d) above. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages and liabilities referred to in paragraph
(d) above shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, the Initial Purchaser shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Securities resold by it in the initial placement of
such Securities were offered to investors exceeds the amount of any damages
that the Initial Purchaser has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          (f) The indemnity and contribution provisions contained in this
Section 7 and the representations and warranties of the Guarantors and the
Company contained in this Agreement shall remain operative and in full force
and effect regardless of (i) termination of this Agreement, (ii) any
investigation made by or on behalf of the Initial Purchaser or any person
controlling the Initial Purchaser or by or on behalf of any Guarantor or the
Company, their officers or directors or any person controlling any Guarantor
or the Company and (iii) acceptance of and payment for any of the Securities.
The remedies provided for in this Section 7 are not exclusive and shall not
limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     8.   Termination. This Agreement shall be subject to termination in the
absolute discretion of the Initial Purchaser, by notice given by it to the
Company, if (a) after the execution and delivery of this Agreement and prior
to the Closing Date (i) trading generally shall have been suspended or
materially limited on or by, as the case

                                                                            15


may be, the New York Stock Exchange, the American Stock Exchange, or the
National Association of Securities Dealers, Inc., (ii) trading of any
securities of any Guarantor or the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities or (iv) there shall have occurred any
outbreak or escalation of hostilities or any change in financial markets or
any calamity or crisis that, in the Initial Purchaser's judgment, is material
and adverse and (b) in the case of any of the events specified in clauses
(a)(i) through (iv), such event singly or together with any other such event
makes it, in the Initial Purchaser's judgment, impracticable to market the
Securities on the terms and in the manner contemplated in the Memorandum.

     9.   Miscellaneous.

          (a) This Agreement may be signed in any number of counterparts, each
of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument.

          (b) If this Agreement shall be terminated by the Initial Purchaser
because of any failure or refusal on the part of any Guarantor or the Company
to comply with the terms or to fulfill any of the conditions of this
Agreement, or if for any reason any Guarantor or the Company shall be unable
to perform its obligations under this Agreement, or because of any termination
pursuant to Section 8 hereof (other than by reason of a default by the Initial
Purchaser), the Guarantors and the Company will reimburse the Initial
Purchaser for all out-of-pocket expenses (including the reasonable fees and
disbursements of their counsel) reasonably incurred by the Initial Purchaser
in connection with this Agreement or the offering contemplated hereunder.

          (c) All notices and other communications under this Agreement shall

                              Form of Opinion of
                            Cravath, Swaine & Moore

               (i) No authorization, approval or other action by, and no
          notice to, consent of, order of, or filing with, any United States
          Federal, New York or, to the extent required under the General
          Corporation Law of the State of Delaware, governmental authority or
          regulatory body is required for the consummation of the transactions
          contemplated by the Purchase Agreement, except such as may be
          required under the blue sky laws of any jurisdiction in connection
          with the purchase and distribution of the Securities by the Initial
          Purchaser;

               (ii) (A) The statements in the Memorandum under the caption
          "Description of the Notes," insofar as such statements purport to
          summarize provisions of the Securities, fairly summarize such
          provisions, and (B) the statements in the Memorandum under the
          caption "Certain United States Federal Income Tax Consequences,"
          insofar as they purport to describe the material tax consequences of
          an investment in the Securities, fairly summarize the matters
          therein described;

               (iii) Assuming (i) the accuracy of the representations and
          warranties of the Company, each of the Guarantors and the Initial
          Purchaser set forth in the Purchase Agreement, (ii) the due
          performance by the Company, each of the Guarantors and the Initial
          Purchaser, of the covenants and agreements set forth in the Purchase
          Agreement, (iii) the Initial Purchaser's compliance with the
          offering and transfer procedures and restrictions described in the
          Memorandum and (iv) the accuracy of the representations and
          warranties made in accordance with the Purchase Agreement and the
          Memorandum by purchasers to whom the Initial Purchaser initially
          resells the Securities, the offer, sale and delivery of the
          Securities to the Initial Purchaser in the manner contemplated by
          the Purchase Agreement and the Memorandum and the initial resale of
          the Securities by the Initial Purchaser in the manner contemplated
          in the Memorandum and the Purchase Agreement, do not require
          registration under the Securities Act of 1933, as amended, it being
          understood that no opinion is expressed as to any subsequent resale
          of any Securities;

               (iv) Neither the Company nor any of the Guarantors is required
          to register as an "investment company" and, after giving effect to
          the offer, issuance and delivery of the Securities in accordance
          with the terms of the Purchase Agreement and the application of the
          proceeds thereof as described in the Memorandum, neither the Company
          nor any of the Guarantors will be required to register as an
          "investment Company" under the Investment Company Act of 1940, as
          amended;

               (v) Each of the Original Indenture, the First Supplemental
          Indenture and the Registration Rights Agreement constitute legal,
          valid and binding obligations of the Company and each Guarantor,
          enforceable against the Company and each Guarantor in accordance
          with their terms (subject to applicable bankruptcy, insolvency,
          fraudulent transfer, reorganization, moratorium or other similar
          laws affecting creditors'

          rights generally from time to time in effect and to general
          principles of equity, including, without limitation, concepts of
          materiality, reasonableness, good faith and fair dealing, regardless
          of whether such enforceability is considered in a proceeding in
          equity or at law);

               (vi) The Securities when executed, issued and authenticated in
          accordance with the provisions of the Indenture and delivered to the
          Initial Purchaser against payment therefor in accordance with the
          provisions of the Purchase Agreement, will be legal, valid and
          binding obligations of the Company, enforceable against the Company
          in accordance with their terms and entitled to the benefits of the
          Indenture (subject to applicable bankruptcy, insolvency, fraudulent
          transfer, reorganization, moratorium or other laws affecting
          creditors' rights generally from time to time in effect and to
          general principles of equity, including, without limitation,
          concepts of materiality, reasonableness, good faith and fair
          dealing, regardless of whether such enforceability is considered in
          a proceeding in equity or at law); in expressing the opinion set
          forth in this paragraph (vi), such counsel may assume, with the
          consent of the Initial Purchaser, that the form of the Securities
          will conform to that included in the Indenture; and

               (vii) Upon execution and delivery of the First Supplemental
          Indenture by the Guarantors and the Company, the Guarantees will be
          legal, valid and binding obligations of each of the Guarantors,
          enforceable against each of the Guarantors in accordance with their
          terms and entitled to the benefits of the Indenture (subject to
          applicable bankruptcy, insolvency, fraudulent transfer,
          reorganization, moratorium or other laws affecting creditors' rights
          generally from time to time in effect and to general principles of
          equity, including, without limitation, concepts of materiality,
          reasonableness, good faith and fair dealing, regardless of whether
          such enforceability is considered in a proceeding in equity or at
          law);

and to such further effect with respect to other legal matters relating to the
Purchase Agreement and the sale of the Securities thereunder as counsel for
the Initial Purchaser may reasonably request.

          Such opinion shall also state that, in connection with the
preparation of the Memorandum, such counsel has participated in conferences
with certain officers of, and with the accountants and counsel for, the
Guarantors and the Company concerning the preparation of the Memorandum. Such
opinion may state that although such counsel has made certain inquiries and
investigations in connection with the preparation of the Memorandum, the
limitations inherent in the role of outside counsel are such that such counsel
does not assume responsibility for the accuracy or completeness of the
statements made in the Memorandum, except insofar as the statements relate to
such counsel and except to the extent set forth in paragraph (ii) of such
counsel's opinion dated the date hereof. Subject to the foregoing, such
opinion shall state that such counsel advises the Initial Purchaser that their
work in connection with this matter did not disclose any information that gave
such counsel reason to believe that the Memorandum (except the financial
statements and other information of a statistical, accounting or financial
nature included or incorporated by reference therein, as to which such counsel
does not express any view) as of its date or the date hereof, included or
includes an

          make such qualification necessary, except to the extent that the
          failure to so qualify or be in good standing would not have a
          Material Adverse Effect;

               (iii) ATA is a "citizen of the United States" (as defined in

          carrier, and for ExecuJet to conduct its business as an air taxi,

          FAA (other than proceedings for the renewal of temporary rights), in
          which the opinion of such counsel might reasonably result in a final

          either of their FAA Operating Certificates or FAA Operating

          adequately disclosed in the Prospectus;

               (xii) to the best knowledge of such counsel, no consent,

contains an untrue statement of a material fact or omitted or omits to state a
material fact necessary in order to make the statements therein in the light
of the circumstances under which they were made not misleading, except that
such counsel need express no opinion with respect to the financial statements,
schedules and other financial data included in the Memorandum.
