     and (B) neither the Prospectus nor any amendment or supplement thereto
     includes or will include an untrue statement of a material fact or omits or

shall be allocated among the Underwriters in the manner determined by you and
the other Underwriters. Such payment will be made on the Closing Date
simultaneously with the issuance and sale of the Securities to the Underwriters.
Payment of such compensation shall be made by Federal funds check or other
immediately available funds.

          The Company hereby agrees that, without your prior written consent on
behalf of the Underwriters, it will not, during the period beginning on the date
hereof and continuing to and including the Closing Date, offer, sell, contract
to sell or otherwise dispose of any debt or pass through certificates of the
Company, or cause a trustee or other entity to offer, sell, contract to sell or
otherwise dispose of any debt or pass through certificates, substantially
similar to the Securities (other than the sale of the Securities under this
Agreement and the sale of the Class C Certificates pursuant to a private
placement).

                    25. Terms of Offering. You have advised the Company that the
             Underwriters will make an offering of the Securities purchased by
             the Underwriters on the terms to be set forth in the Prospectus, as
             soon as practicable after this Agreement is entered into as in your
             judgment is advisable. You have further advised the Company that
             the Securities are to be offered to the public initially at 100% of
             their principal amount (which shall be the public offering price)
             plus accrued interest, if any, to the Closing Date and to certain
             dealers selected by the Underwriters at concessions not in excess
             of the concessions set forth in the Prospectus, and that the
             Underwriters may allow, and such dealers

                                       9
<PAGE>

             may reallow, concessions not in excess of the concessions set forth
             in the Prospectus to certain other dealers.

                    26. Payment and Delivery. Payment for the Securities shall
             be made to the Company in Federal or other funds immediately
             available in Chicago, Illinois against delivery of such Securities
             for the respective accounts of the several Underwriters at 10:00
             a.m., Chicago, Illinois time, on July 31, 2000, or at such other
             time on the same or such other date, not later than July 31, 2000,
             as shall be designated in writing by you at the place indicated in
             Schedule III. The time and date of such payment are referred to as
             the "Closing Date."

          Certificates for the Securities shall be in definitive form or global
form, as specified by you, and registered in such names and in such
denominations as you shall request in writing not later than one full business
day prior to the Closing Date. The certificates evidencing the Securities shall
be delivered to you on the Closing Date for the respective accounts of the
several Underwriters, with any transfer taxes payable in connection with the
transfer of the Securities to the Underwriters duly paid, against payment of the
Purchase Price therefor plus accrued interest, if any, to the date of payment
and delivery.

                    27. Conditions to the Underwriters' Obligations. The several
             obligations of the Underwriters to purchase and pay for the
             Securities on the Closing Date are subject to the following
             conditions:

          (a) Subsequent to the execution and delivery of this Agreement and as
     of the Closing Date:

             (1) there shall not have occurred any downgrading, nor shall any
                 notice have been given of any intended or potential downgrading
                 or of any review for a possible change that does not indicate
                 the direction of the possible change, in the rating accorded
                 the Company or any of the Company's securities by Moody's
                 Investors Service, Inc. ("Moody's") or Standard & Poor's
                 Ratings Services, a division of The McGraw-Hill Companies, Inc.
                 ("Standard & Poor's");

             (2) the Securities shall be rated (x) not lower than "AAA", in the
                 case of the Securities of the Class A-1 Trust, not lower than
                 "AAA", in the case of the Securities of the Class A-2 Trust,
                 and not lower than "AA-", in the case of the Securities of the
                 Class B Trust by Standard & Poor's, and (y) not lower than
                 "Aa2", in the case of the Securities of the Class A-1 Trust,
                 not lower than "Aa2", in the case of the Securities of the
                 Class A-2 Trust and not lower than "A1", in the case of the
                 Securities of the Class B Trust, by Moody's;

                                       10
<PAGE>

             (3)  there shall not have occurred any change, or any development
                  involving a prospective change, in the condition (financial or
                  otherwise), earnings or business of the Company and its
                  subsidiaries, taken as a whole, or of AFE, from that set forth
                  in the Prospectus (exclusive of any amendments or supplements
                  thereto after the date of this Agreement) that, in your
                  reasonable judgment, is material and adverse and that makes
                  it, in your reasonable judgment, impracticable to market the
                  Securities on the terms and in the manner contemplated in the
                  Prospectus; and

             (4)  on the Closing Date, the Fundamental Documents to which each
                  of the Company and AFE is a party will have been duly executed
                  and delivered by the Company or AFE, as the case may be, and
                  will be in full force and effect.

         (b) You shall have received on the Closing Date a certificate, dated
     the Closing Date and signed by the Senior Vice President - Finance or the
     Senior Vice President-General Counsel and Secretary of the Company, to the
     effect set forth in Section 5(a)(1) and to the effect that the
     representations and warranties of the Company contained in this Agreement
     are true and correct as of the Closing Date (except to the extent they
     relate solely to an earlier date, in which case they shall be true and
     correct as of such earlier date) with the same force and effect as if made
     on and as of the Closing Date and that the Company has complied with all of
     the agreements and satisfied all of the conditions on its part to be
     performed or satisfied hereunder on or before the Closing Date.

          (c) You shall have received on the Closing Date an opinion of Mayer,
     Brown & Platt, special counsel for the Company, dated the Closing Date,
     substantially to the effect set forth in Exhibit A.

          (i) You shall have received on the Closing Date an opinion of
     Richards, Layton & Finger, special counsel for Wilmington Trust Company as
     AFE Trustee, dated the Closing Date, substantially to the effect set forth
     in Exhibit G.

          (j) You shall have received on the Closing Date an opinion of Milbank,
     Tweed, Hadley & McCloy LLP, counsel for the Underwriters, dated the Closing
     Date, with respect to the issuance and sale of the Certificates, the
     Registration Statement, the Prospectus and such other matters as you shall
     reasonably require and in form and substance reasonably acceptable to you.

          (k) You shall have received on each of the date hereof and the Closing
     Date a letter, dated the date hereof or the Closing Date, as the case may
     be, in form and substance reasonably satisfactory to the Underwriters, from
     Arthur Andersen LLP, independent public accountants, containing statements
     and information of the type ordinarily included in accountants' "comfort
     letters" to underwriters with respect to the financial statements and
     certain financial information contained in, or incorporated by reference
     into, the Registration Statement and the Prospectus.

          (l) Each of the Appraisers shall have furnished to you a letter from
     such Appraiser, addressed to the Company and AFE and dated the Closing
     Date, confirming that such Appraiser and each of its directors and officers
     (i) is not an affiliate of the Company, AFE or any of their respective
     affiliates, (ii) does not have any substantial interest, direct or
     indirect, in the Company, AFE or any of their respective affiliates and
     (iii) is not connected with the Company, AFE or any of their respective
     affiliates as an officer, employee, promoter, underwriter, trustee,
     partner, director or person performing similar functions.

          (m) On or prior to the Closing Date, the conditions precedent set
     forth in Section 3 of the AFE Note Purchase Agreement, in Section 3 of the
     747 Leased Equipment Note Purchase Agreement and in Section 3 of the United
     Equipment Note Purchase Agreement shall have been fulfilled to your

          (n) At the Closing Date, the Class C Certificates shall have been duly
     issued and privately placed.

                                       12

                    16. Covenants of the Company. In further consideration of
             the agreements of the Underwriters contained in this Agreement, the
             Company covenants with each Underwriter as follows:

          (a) To furnish to you, without charge, as soon as available and during
     the period mentioned in Section 6(d), as many copies of the Prospectus, any
     documents incorporated by reference therein and any supplements and
     amendments thereto as you may reasonably request.

          (b) Before amending or supplementing the Prospectus, to furnish to you
     a copy of each such proposed amendment or supplement and not to use any
     such proposed amendment or supplement to which you reasonably object.

          (c) To cause AFE to use on the Closing Date the applicable portion of
     the proceeds received by AFE as specified in the Prospectus from the sale
     of the AFE Notes to purchase the corresponding amount of Leased Equipment
     Notes.

          (d) If, during such period after the first date of the public offering
     of the Securities as in the opinion of counsel for the Underwriters the
     Prospectus is required by law to be delivered in connection with sales by
     an Underwriter, any event shall occur as a result of which it is necessary
     to amend or supplement the Prospectus in order to make the statements
     therein, in the light of the circumstances when the Prospectus is delivered
     to a purchaser, not misleading, or if it is necessary to amend or
     supplement the Prospectus to comply with law, forthwith to prepare and
     furnish, at its own expense, to the Underwriters, either amendments or
     supplements to the Prospectus so that the statements in the Prospectus as
     so amended or supplemented will not, in the light of the circumstances when
     the Prospectus is delivered to a purchaser, be misleading or so that the
     Prospectus, as amended or supplemented, will comply with law and to cause
     such amendments or supplements to be filed promptly.

          (e) To endeavor, in cooperation with the Underwriters, to qualify the
     Securities for offer and sale under the securities or Blue Sky laws of such
     jurisdictions as you shall reasonably request, and to maintain such
     qualifications for so long as required for the distribution of the
     Securities; provided, however, that the Company shall not be obligated to
     file any general consent to service of process or to qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction in which it is
     not so qualified or to subject itself to taxation in respect of doing
     business in any jurisdiction in which it is not otherwise so subject.

          (f) Whether or not the transactions contemplated in this Agreement are
     consummated or, subject to the last paragraph of Section 9, this Agreement
     is terminated, to pay or cause to be paid all expenses incident to the
     performance of its obligations under this Agreement, including: (i) the
     fees, disbursements and expenses of the Company's counsel and the Company's
     accountants in connection with the issuance and sale of the Securities and
     all other fees or expenses in connection with the preparation of the
     Prospectus and all

                                       13
<PAGE>

     amendments and supplements thereto, including all printing costs associated
     therewith, and the delivering of copies thereof to the Underwriters in the
     quantities reasonably specified, (ii) all costs and expenses related to the
     preparation, issuance, transfer and delivery of the Securities to the
     Underwriters, including any transfer or other taxes payable thereon, (iii)
     the cost of producing any Blue Sky or legal investment memorandum in
     connection with the offer and sale of the Securities under state securities
     laws and all expenses in connection with the qualification of the
     Securities for offer and sale under state securities laws as provided in
     Section 6(e) hereof, including filing fees and the reasonable fees and
     disbursements of counsel for the Underwriters in connection with such
     qualification and in connection with the Blue Sky or legal investment
     memorandum, (iv) any fees charged by rating agencies for the rating of the
     Securities, (v) the fees and expenses, if any, incurred in connection with
     the admission of the Securities for trading in any appropriate market
     system, (vi) the costs and charges of the Trustee, the AFE Trustee, the
     Liquidity Provider, the Subordination Agent, the Indenture Trustees, their
     respective counsel and any transfer agent, registrar or depositary, (vii)
     all reasonable fees and disbursements of counsel for the Underwriters and
     (viii) all other costs and expenses incident to the performance of the
     obligations of the Company or AFE hereunder or under the Fundamental
     Documents for which provision is not otherwise made in this Section. It is
     understood, however, that except as provided in this Section 6, Section 7
     and the last paragraph of Section 9, the Underwriters will pay all of their
     costs and expenses, transfer taxes payable on resale of any of the
     Securities by them and any advertising expenses connected with any offers
     they may make.

          7. Indemnity and Contribution. (a) The Company will indemnify and hold
     harmless each Underwriter and each person, if any, who controls any
     Underwriter within the meaning of either Section 15 of the Securities Act
     or Section 20 of the Exchange Act from and against any and all losses,
     claims, damages and liabilities, joint or several, (including, without
     limitation, any legal or other expenses reasonably incurred 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 Registration Statement, the Prospectus, any related preliminary
     prospectus or related preliminary prospectus supplement (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
     the light of the circumstances under which they were made not misleading,
     and shall reimburse each Underwriter and each such controlling person
     promptly upon demand for any legal or other expenses reasonably incurred by
     that Underwriter or controlling person in connection with investigating or
     defending or preparing to defend against any such loss, claim, damage or
     liability as such expenses are incurred; 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 and in
     conformity with information relating to any Underwriter furnished to the
     Company in writing by such Underwriter through you expressly for use
     therein.

                                       14
<PAGE>

          (b) Each Underwriter, severally and not jointly, will indemnify and
     hold harmless the Company and each person, if any, who controls the Company
     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 the
     Company to such Underwriter described in Section 7(a), but only with
     reference to information relating to such Underwriter furnished to the
     Company in writing by such Underwriter through you expressly for use in the
     Prospectus or any amendments or supplements thereto, and shall reimburse
     the Company and any such controlling person for any legal or other expenses
     reasonably incurred by the Company or any such controlling person in
     connection with any such loss, claim, damage or liability as such expenses
     are incurred.

          (c) If any proceeding (including any governmental investigation) shall
     be instituted involving any person in respect of which indemnity may be
     sought pursuant to Section 7(a) or 7(b), 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 respect of the legal expenses of any indemnified party 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 you, in the case of
     parties indemnified pursuant to Section 7(a), and by the Company, in the
     case of parties indemnified pursuant to Section 7(b). 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
     of 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

                                       15
<PAGE>

     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 Section 7(a) or
     7(b) is unavailable to an indemnified party or insufficient in respect of
     any losses, claims, damages or liabilities referred to therein, 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 Company on the one hand and the
     Underwriters on the other hand from the offering of the Securities or (ii)
     if the allocation provided by clause 7(d)(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 7(d)(i) above but also the
     relative fault of the Company on the one hand and of the Underwriters 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
     Company on the one hand and the Underwriters on the other hand in
     connection with the offering of the Securities shall be deemed to be in the
     same respective proportions as the net proceeds from the offering of the
     Securities (before deducting expenses) received by the Company and the
     total discounts and commissions received by the Underwriters, in each case
     as set forth in the Prospectus, bear to the aggregate offering price of the
     Securities. The relative fault of the Company on the one hand and of the
     Underwriters 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 the Company or by the Underwriters and the
     parties' relative intent, knowledge, access to information and opportunity
     to correct or prevent such statement or omission. The Underwriters'
     respective obligations to contribute pursuant to this Section 7 are several
     in proportion to the respective principal amount of Securities they have
     purchased hereunder, and not joint.

          (e) The Company and the Underwriters agree that it would not be just
     or equitable if contribution pursuant to this Section 7 were determined by
     pro rata allocation (even if the Underwriters were treated as one entity
     for such purpose) or by any other method of allocation that does not take
     account of the equitable considerations referred to in Section 7(d). The
     amount paid or payable by an indemnified party as a result of the losses,
     claims, damages and liabilities referred to in Section 7(d) 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, no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Securities underwritten by it and distributed to the public were
     offered to the public exceeds the amount of any damages that such
     Underwriter has otherwise been required to pay by

                                       16
<PAGE>

     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. 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.

          (f) The indemnity and contribution provisions contained in this
     Section 7 and the representations, warranties and other statements of the
     Company contained in this Agreement shall remain operative and in full
     force and effect regardless of (i) any termination of this Agreement, (ii)
     any investigation made by or on behalf of any Underwriter or any person
     controlling any Underwriter or by or on behalf of the Company, its officers
     or directors or any person controlling the Company and (iii) acceptance of
     and payment for any of the Securities.

                    7. Termination. This Agreement shall be subject to
             termination by notice given by you 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 the New York Stock Exchange, (ii) trading of any
             securities of the Company or of UAL Corporation shall have been
             suspended on any exchange or in any overthecounter 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 major hostilities in which the United States is
             involved or any change in financial markets or any calamity or
             crisis that, in your reasonable judgment, is material and adverse
             and (b) in the case of any of the events specified in clauses
             8(a)(i) through 8(a)(iv), such event, singly or together with any
             other such event, makes it, in your reasonable judgment,
             impracticable or inadvisable to proceed with the public offering or
             delivery of the Securities on the terms and in the manner
             contemplated in the Prospectus.

                    8. Effectiveness; Defaulting Underwriters. This Agreement
             shall become effective upon the execution and delivery hereof by
             the parties hereto. If, on the Closing Date, any one or more of the
             Underwriters shall fail or refuse to purchase Securities that it or
             they have agreed to purchase hereunder on such date, and the
             aggregate principal amount of Securities which such defaulting
             Underwriter or Underwriters agreed but failed or refused to
             purchase is not more than onetenth of the aggregate principal
             amount of Securities to be purchased on such date, the other
             Underwriters shall be obligated severally in the proportions that
             the principal amount of Securities set forth opposite their
             respective names in Schedule II bears to the aggregate principal
             amount of Securities set forth opposite the names of all such
             nondefaulting Underwriters, or in such other proportions as you may
             specify, to purchase the Securities which such defaulting
             Underwriter or Underwriters agreed but failed or refused to
             purchase on such

                                       17
<PAGE>

             date; provided that in no event shall the principal amount of
             Securities that any Underwriter has agreed to purchase pursuant to
             this Agreement be increased pursuant to this Section 9 by an amount
             in excess of oneninth of such principal amount of Securities
             without the written consent of such Underwriter. If, on the Closing
             Date any Underwriter or Underwriters shall fail or refuse to
             purchase Securities which it or they have agreed to purchase
             hereunder on such date and the aggregate principal amount of
             Securities with respect to which such default occurs is more than
             onetenth of the aggregate principal amount of Securities to be
             purchased on such date, and arrangements satisfactory to you and
             the Company for the purchase of such Securities are not made within
             36 hours after such default, this Agreement shall terminate without
             liability on the part of any nondefaulting Underwriter or of the
             Company, except as provided in Section 6(f) and Section 7.
             Otherwise, either you or the Company shall have the right to
             postpone the Closing Date, but in no event for longer than seven
             business days, in order that the required changes, if any, in the
             Prospectus or in any other documents or arrangements may be
             effected. Any action taken under this paragraph shall not relieve
             any defaulting Underwriter from liability in respect of any default
             of such Underwriter under this Agreement.

          If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, or if for
any reason the Company shall be unable to perform its obligations under this
Agreement, in either case other than in connection with a termination specified
in Section 8 (in which case the provisions of Section 6(f) and Section 7 shall
remain in effect), the Company will reimburse the Underwriters or such
Underwriters as have so terminated this Agreement with respect to themselves,
severally, for all outofpocket expenses (including the fees and disbursements of
their counsel) reasonably incurred by such Underwriters in connection with this
Agreement or the offering contemplated hereunder.
