                                 ------------
  Each Pass Through Certificate offered hereby (collectively, the
"Certificates") will represent a fractional undivided interest in one of the
two United Airlines 1996-A Pass Through Trusts (the "1996-A1 Trust" and the
"1996-A2 Trust" and, collectively, the "Trusts") to be formed pursuant to two
separate trust supplements (each, a "Trust Supplement") between United Air
Lines, Inc. ("United") and First Security Bank of Utah, National Association
(the "Trustee"), as trustee under each Trust, which supplement the Pass Through
Trust Agreement dated as of February 1, 1992, as amended and restated as of May
1, 1995 (the "Basic Agreement"). Upon purchase of the related Equipment Notes,
the property of the Trusts will consist of equipment notes (the "Equipment
Notes") to be issued on a nonrecourse basis by the trustees of separate owner
trusts (each, an "Owner Trustee") in connection with two separate leveraged
lease transactions to refinance not more than 80% of the equipment cost to the
related Owner Trustee of one Boeing 777-222 aircraft and one Boeing 747-451
aircraft (collectively, the "Aircraft") which have been leased to United.
  The Equipment Notes in respect of each Aircraft will be issued in two series.
Each Trust will purchase one series of the Equipment Notes issued with respect
to each of the Aircraft such that all of the Equipment Notes held in each Trust
will have an interest rate corresponding to the interest rate applicable to
such Trust. The maturity dates of the Equipment Notes acquired by each Trust
will occur on or before the final distribution date applicable to the
Certificates issued by such Trust. The Equipment Notes issued with respect to
each Aircraft will be secured by a security interest in such Aircraft and an
assignment of the Lease relating thereto, including the right to receive
rentals payable with respect to such Aircraft by United. Although neither the
Certificates nor the Equipment Notes are direct obligations of, or guaranteed
by, United, the amounts unconditionally payable by United for lease of the
Aircraft will be sufficient to pay in full when due all payments required to be
made on the Equipment Notes held in the Trusts.

S-2 PROSPECTUS SUPPLEMENT SUMMARY The following summary does not purport to be complete and is qualified in its entirety by the detailed information appearing elsewhere in this Prospectus Supplement and the Prospectus accompanying this Prospectus Supplement (the "Prospectus"). THE COMPANY United is a wholly-owned subsidiary of UAL Corporation ("UAL"), accounting for virtually all of UAL's revenues and expenses in 1995. United is one of the world's largest airlines, as measured by operating revenues, revenue passengers and revenue passenger miles flown. As of December 31, 1995, United served 144 airports in the United States and 30 foreign countries. During 1995, United averaged 2,172 departures daily, flew a total of 112 billion revenue passenger miles and carried an average of 215,521 passengers per day. As of December 31, 1995, United's fleet of aircraft totaled 558. United's major hub operations are located at Chicago, Denver, San Francisco, Washington, D.C. and Tokyo. THE OFFERING Glossary.............. Included at the end of this Prospectus Supplement as an Appendix is a Glossary of certain of the significant defined terms used herein. Trusts................ The 1996-A1 Trust and the 1996-A2 Trust are each to be formed pursuant to a separate Trust Supplement to the Basic Agreement. Each Trust will be a separate entity. Trust Property........ The property of each of the Trusts will consist of Equipment Notes issued on a nonrecourse basis in two separate leveraged lease transactions to refinance not more than 80% of the equipment cost to the related Owner Trustee of one Boeing 777-222 aircraft delivered and leased by the related Owner Trustee to United in May 1995 (the "777 Aircraft") and one Boeing 747-451 aircraft delivered and leased by the related Owner Trustee to United in August 1994 (the "747 Aircraft"). The Equipment Notes with respect to each of the two Aircraft will be issued by the related Owner Trustee in two series. The maturity dates of the Equipment Notes acquired by each Trust will occur on or before the final distribution date applicable to the Certificates issued by such Trust. The aggregate principal amount of the Equipment Notes to be held in each Trust will be the same as the aggregate principal amount of the Certificates issued by that Trust. Certificates Offered;Book-Entry Registration......... Each Certificate will represent a fractional undivided interest in the related Trust. The Certificates of each Trust will be issued in fully registered form only and will be registered in the name of Cede & Co. ("Cede"), as the nominee of The Depository Trust Company ("DTC"). No person acquiring an interest in the Certificates will be entitled to receive a definitive certificate representing such person's interest in the Trust, unless definitive certificates are issued, which will only occur under limited circumstances. See "Description of the Certificates--General" in this Prospectus Supplement and "Description of the Certificates--General", "--Book-Entry Registration" and "--Definitive Certificates" in the Prospectus. Regular Distribution Dates................ January 30 and July 30. S-3 Special Distribution Dates................ Any Business Day on which a Special Payment is to be distributed. Record Dates.......... The fifteenth day preceding a Regular Distribution Date or a Special Distribution Date. Distributions......... Payments of interest with respect to the respective Equipment Notes held in each Trust will be distributed by the Trustee to the Certificateholders of such Trust on the Regular Distribution Dates referred to above commencing July 30, 1996, except in certain circumstances. Payments of principal on the respective Equipment Notes held in each Trust are scheduled to be received in specified amounts by the Trustee of such Trust on January 30 or July 30, or both, of certain years, commencing , , in the case of the 1996-A1 Trust, and , , in the case of the 1996-A2 Trust, and to be distributed to the Certificateholders of such Trust on the corresponding Regular Distribution Date. Payments of principal, premium, if any, and interest resulting from the early redemption or purchase, if any, of the Equipment Notes held in any Trust will be distributed on a Special Distribution Date after not less than 20 days' notice from the Trustee to the Certificateholders of such Trust. For a discussion of distributions upon an Event of Default, see "Description of the Certificates-- Events of Default and Certain Rights Upon an Event of Default" in the Prospectus. Method of Distribution......... Under the terms of the Basic Agreement, United and the Trustee will treat the persons in whose names the Certificates are registered as the owners of such Certificates for the purpose of receiving payments of principal and interest on such Certificates and for all other purposes whatsoever. So long as the Certificates are registered in the name of Cede, as nominee of DTC, distributions by the Trustee, including the final distribution of principal with respect to the Certificates of any Trust, will be made in same-day funds to DTC. See "Description of Certificates--Same- Day Settlement and Payment" in the Prospectus. DTC will in turn make distributions in same-day funds to those participants in DTC who are credited with ownership of the Certificates ("DTC Participants") in amounts proportionate to the amount of each such DTC Participant's respective holdings of beneficial interests in such Certificates. Corresponding payments by the DTC Participants to beneficial owners of the Certificates will be the responsibility of such DTC Participants and will be made in accordance with customary industry practices. See "Description of the Certificates--Book-Entry Registration" in the Prospectus. Therefore, neither United nor the Trustee has any direct responsibility or liability for distributions or payments to owners of beneficial interests in the Certificates (the "Certificate Owners"). At such time, if ever, as the Certificates are issued in definitive form and not registered in the name of Cede, as nominee for DTC, distributions by the Trustee to Certificateholders, other than the final distribution, will be made by check mailed to each Certificateholder of record on the applicable record date at its address appearing on the register. The final distribution with respect to the Certificates of any Trust will be made only upon surrender and presentation thereof at the office or agency of the Trustee. See "Description of the Certificates-- Definitive Certificates" in the Prospectus. S-4 Equipment Notes: Interest............. Interest will be payable on the Equipment Notes held in each Trust on the unpaid principal amount thereof on January 30 and July 30 of each year, commencing July 30, 1996, which interest will be passed through to Certificateholders of such Trust on each such date. Interest is calculated on the basis of a 360-day year consisting of twelve 30-day months. See "Description of the Certificates--General" and"--Payments and Distributions" in this Prospectus Supplement. Equipment Notes: Principal............ Scheduled principal payments on the Equipment Notes held in each Trust will be passed through to the Certificateholders of such Trust on January 30 or July 30, or both, of certain years, commencing , , in the case of the 1996-A1 Trust, and , , in the case of the 1996-A2 Trust, in accordance with the principal repayment schedule set forth below under "Description of Equipment Notes-- General". See "Description of the Certificates-- Payments and Distributions" in the Prospectus and this Prospectus Supplement. Equipment Notes: Redemption........... (a) The Equipment Notes issued with respect to an Aircraft will be redeemed in whole upon the occurrence of an Event of Loss to such Aircraft if such Aircraft is not replaced by United and, with respect to the 777 Aircraft, will be redeemed in part upon the occurrence of an Event of Loss with respect to an Engine under certain circumstances specified in the related Lease, in each case at a price equal to the Redemption Price (as defined in the Glossary), but without any premium. (b) If, with respect to an Aircraft, (i) one or more Lease Events of Default shall have occurred and be continuing for a period of one year or more and the Equipment Notes issued with respect to such Aircraft shall not have been accelerated or (ii) the Equipment Notes with respect to such Aircraft shall have been accelerated, then in each case the Equipment Notes issued with respect to such Aircraft may be redeemed or purchased by the related Owner Trustee or Owner Participant on the applicable redemption or purchase date at a price equal to the Redemption Price, but without any premium. (c) The Equipment Notes may under certain other circumstances be redeemed or purchased on the applicable redemption or purchase date at a price equal to the Redemption Price, plus, if such redemption or purchase is made prior to the respective dates set forth below, a premium, if any:
PREMIUM TRUST TERMINATION DATE ----- ---------------- 1996-A1................. 1996-A2.................
See "Description of the Equipment Notes--Redemption" in this Prospectus Supplement for a description of the manner of computing such premium and the circumstances under which the Equipment Notes may be so redeemed or purchased. S-5 Equipment Notes: Security............. The Equipment Notes issued with respect to each Aircraft will be secured by a security interest in such Aircraft and an assignment to the related Loan Trustee of certain of the related Owner Trustee's rights under the Lease with respect to such Aircraft, including the right to receive payments of rent thereunder, with certain exceptions. The Equipment Notes are not cross- collateralized and, consequently, the Equipment Notes issued in respect of any one Aircraft are not secured by the other Aircraft or the Lease related thereto. There are no cross-default provisions in the Indentures and, consequently, events resulting in an Indenture Default under either Indenture will not necessarily result in an Indenture Default occurring under the other Indenture. If the Equipment Notes issued with respect to one Aircraft are in default, the Equipment Notes issued with respect to the remaining Aircraft may not be in default and, if not in default, no remedies will be exercisable under the Indenture with respect to such other Aircraft. See "Description of the Equipment Notes--Security" in the Prospectus and "Description of the Equipment Notes--Indenture Defaults, Notice and Waiver" in this Prospectus Supplement. Although the Equipment Notes are not obligations of, or guaranteed by, United, the amounts unconditionally payable by United for lease of the Aircraft will be sufficient to pay in full when due all payments required to be made on the Equipment Notes. See "Description of the Equipment Notes--General" in the Prospectus and this Prospectus Supplement. Use of Proceeds....... The proceeds from the sale of the Certificates will be used in part to purchase the Equipment Notes issued by the related Owner Trustees in connection with the refinancing of not more than 80% of the equipment cost to the Owner Trustees of each of the Aircraft. The Equipment Notes will represent in the aggregate the entire debt portion of the leveraged lease transactions relating to the two Aircraft. The remainder of the proceeds will be used to reduce the initial equity investments in the Aircraft by the related Owner Participants. See "Use of Proceeds" in this Prospectus Supplement. Trustee............... First Security Bank of Utah, National Association ("First Security"), will act as Trustee and as paying agent and registrar for the Certificates of each Trust. First Security also acts as Loan Trustee and as paying agent and registrar for each series of Equipment Notes. Federal Income Tax Consequences......... Each Trust will be classified as a grantor trust for federal income tax purposes and therefore each Certificate Owner will be treated as the owner of a pro rata undivided interest in each of the Equipment Notes and any other property held by such Trust and should report on its federal income tax return its pro rata share of income from such Equipment Notes and other property held by such Trust in accordance with such Certificate Owner's method of accounting. See "Federal Income Tax Consequences" in the Prospectus. S-6 THE COMPANY United is a wholly-owned subsidiary of UAL Corporation ("UAL"), accounting for virtually all of UAL's revenues and expenses in 1995. United is one of the world's largest airlines, as measured by operating revenues, revenue passengers and revenue passenger miles flown. As of December 31, 1995, United served 144 airports in the United States and 30 foreign countries. During 1995, United averaged 2,172 departures daily, flew a total of 112 billion revenue passenger miles and carried an average of 215,521 passengers per day. As of December 31, 1995, United's fleet of aircraft totalled 558. United's major hub operations are located at Chicago, Denver, San Francisco, Washington, D.C. and Tokyo. The executive offices of United are located at 1200 East Algonquin Road, Elk Grove Township, Illinois 60007. The mailing address of United is P.O. Box 66100, Chicago, Illinois 60666. The telephone number for United is (847) 952- 4000. RECENT DEVELOPMENTS On January 23, 1996, UAL reported full year 1995 preliminary unaudited net earnings of $349 million. The 1995 earnings, before an after-tax $29 million extraordinary loss on the early extinguishment of debt, were $378 million, a company record for earnings from ongoing operations (before extraordinary items). Earnings per share were $19.11 on a fully diluted basis ($20.01 per share on a primary basis). In 1994, UAL reported net earnings of $51 million, including $128 million of one-time after-tax charges associated with the completion of the recapitalization and a one-time after-tax charge of $26 million associated with the adoption of SFAS No. 112. Operating earnings for 1995 were $829 million on operating revenues of $14,943 million. Operating earnings were $521 million in 1994 on operating revenues of $13,950 million. UAL also reported that on a pro forma, fully distributed basis (see below for further explanation of the methodology) 1995 net earnings were $662 million or $20.51 per share after preferred dividends. Fully distributed operating earnings for 1995 were $1,333 million. UAL reported that available seat miles grew 4.2% in 1995 to 158.6 billion from 152.2 billion in 1994. Traffic increased by 3.2% reflecting growth in revenue passenger miles to 111.8 billion from 108.3 billion in 1994. While the resulting passenger load factor decreased 0.7 points to 70.5% in 1995 from 71.2% in 1994, the breakeven passenger load factor also decreased, by 2.1 points, to 66.1% from 68.2% the prior year. Yield (revenue per passenger mile) increased by 4.2% for the year to 11.79c, up from 11.31c in 1994. For the fourth quarter, UAL reported a net loss of $5 million excluding certain special adjustments, or a loss of $1.25 per share after preferred dividends. In the fourth quarter, UAL recorded the following special adjustments: . An extraordinary loss of $29 million ($2.35 per share) after-tax due to early extinguishment of debt, . A $13 million ($1.09 per share) after-tax adjustment to depreciation associated with a write-down of non-operating aircraft, and . A $1.81 per share unfavorable impact due to the repurchase of a portion of outstanding Series B preferred stock. The fourth quarter net loss including the special adjustments was $47 million or a loss of $6.50 per share after preferred dividends. For the comparable quarter in 1994, UAL reported net income of $11 million (a loss of $0.98 per share after preferred dividends). S-7 On a fully distributed basis, UAL fourth quarter net income, excluding the special adjustments, was $98 million or $2.95 per share for each of the 30.7 million fully distributed shares. The fully distributed net earnings represented a 46% increase from 1994's fourth quarter fully distributed net earnings of $67 million with earnings per share being an 88% improvement over last year's fully distributed earnings per share of $1.57. Fully distributed operating earnings for the quarter, excluding the special adjustments, were $212 million, a 23% improvement over 1994's $172 million. In addition to reviewing financial statements reported under generally accepted accounting principles (GAAP), UAL believes a more complete understanding of its results can be gained by viewing them on a pro forma, fully distributed basis. This approach considers all ESOP shares (which will be issued to employees over the course of the ESOP period) to be immediately outstanding and thus fully distributed. Consistent with this method, the ESOP compensation expense (which reflects the commitment of stock to employees) is excluded from fully distributed expenses and ESOP convertible preferred stock dividends have not been deducted from earnings attributable to common shareholders. S-8 SELECTED FINANCIAL AND OPERATING DATA The following financial information should be read in conjunction with the consolidated financial statements and related notes of United included in its Annual Report on Form 10-K for the year ended December 31, 1994. The following information for the five years ended December 31, 1994 has been derived from United's consolidated financial statements, which statements have been audited by Arthur Andersen LLP, independent public accountants, as indicated in their reports incorporated by reference herein. Reference is made to said reports for the years 1994, 1993 and 1992 which include an explanatory paragraph with respect to the changes in methods of accounting for income taxes and post- retirement benefits other than pensions discussed in the notes to the consolidated financial statements for such years. The financial information for the nine months ended September 30, 1995 and 1994 is unaudited but in the opinion of management includes all adjustments necessary for a fair presentation. See "Incorporation of Certain Documents by Reference" in the Prospectus.

S-9 USE OF PROCEEDS The Certificates are being issued in connection with the refinancing of the debt portion of two separate leveraged lease transactions entered into by United, as lessee, with respect to the 777 Aircraft and the 747 Aircraft. The $ aggregate principal amount of debt currently outstanding with respect to the two Aircraft consists of variable interest rate loan certificates maturing May 29, 2011 and January 30, 2013. In addition to the repayment of such debt, an aggregate of $ of the proceeds will be used to reduce the initial equity investments in the Aircraft by the Owner Participants. The proceeds from the sale of the Certificates are to be used by the Trustees on behalf of the Trusts to purchase $ aggregate principal amount of Equipment Notes issued by the related Owner Trustees to refinance not more than 80% of the equipment cost to such Owner Trustees of the related Aircraft. The 777 Aircraft was delivered new to United in May 1995 and the 747 Aircraft was delivered new to United in August 1994, and each Aircraft was sold to the related Owner Trustee and leased back to United within one month of delivery. The Equipment Notes will be issued under two separate Indentures between First Security, as Loan Trustee thereunder, and State Street Bank and Trust Company of Connecticut, National Association, not in its individual capacity but solely as Owner Trustee of a trust for the benefit of an Owner Participant. Each Owner Participant provided from its own funds at least 20% of the equipment cost of the related Aircraft and beneficially owns the related Aircraft. No Owner Participant, however, will be personally liable for any amount payable under the related Indenture or the Equipment Notes issued thereunder. S-10 DIAGRAM OF PAYMENTS The diagram below illustrates certain aspects of the payment flows among United, the Owner Trustees, the Loan Trustees, the Trustees, the Owner Participants and the Certificateholders with respect to the two Trusts and the two related Aircraft. United has leased each Aircraft under a separate Lease from the Owner Trustee for such Aircraft. The Equipment Notes for each such Aircraft will be issued by such Owner Trustee in two series (each series to be purchased by one of the Trusts) and will be secured by such Aircraft and by an assignment of certain rights of the related Owner Trustee under the related Lease, which assignment requires United to make rental payments for each Aircraft directly to the related Loan Trustee. From these rental payments such Loan Trustee will on behalf of the related Owner Trustee first make payments to the Trustee for each of the Trusts on the Equipment Notes held in such Trust and will pay the remaining balance to the respective Owner Trustee for the benefit of the respective Owner Participant. The Trustee for each of the Trusts will pass through to the Certificateholders payments received with respect to the Equipment Notes held in such Trust. First Security will act as Trustee of each of the two Trusts and as Loan Trustee under the two Indentures. ----------------------------------------------------------------------------- | United Air Lines, Inc. | ----------------------------------------------------------------------------- | | | Lease Rental Payments | | Assigned by | | Owner Trustees | \/ \/ ------------------- ------------------- | Loan Trustee | | Loan Trustee | ----| for | | for |---- | | Aircraft No. 1 | | Aircraft No. 2 | | | ------------------- ------------------- | Excess | | | | Excess Payments | ---------------------------------- | Payments | | 1996-A | | | | Equipment Note Payments | | | | | | \/ \/ \/ \/ - ------------------ ----------------- ----------------- ------------------ | Owner Trustee | | Pass Through | | Pass Through | | Owner Trustee | | for | | Trustee for | | Trustee for | | for | | Aircraft No. 1 | | Pass Through | | Pass Through | | Aircraft No. 2 | | | | Trust 1996-A1 | | Trust 1996-A2 | | | - ------------------ ----------------- ----------------- ------------------ | | | | Excess | | Pass Through | | Excess Payments | | Certificate | | Payments | | Distributions | | | | | | \/ \/ \/ \/ - ------------------ ----------------- ----------------- ------------------ | Owner | | Holders of | | Holders of | | Owner | | Participant for| | Pass Through | | Pass Through | | Participant for| | Aircraft No. 1 | | Certificates, | | Certificates, | | Aircraft No. 2 | | | | Series 1996-A1| | Series 1996-A2| | | - ------------------ ----------------- ----------------- ------------------ S-11 DESCRIPTION OF THE CERTIFICATES The Certificates offered hereby will be issued pursuant to two separate Trust Supplements to the Basic Agreement. The Prospectus provides for the issuance of up to $1,035,000,000 aggregate principal amount of pass through certificates (or such greater amount if issued at an original issue discount as shall result in aggregate proceeds of $1,035,000,000) pursuant to the Basic Agreement, which securities were registered with the Commission on April 27, 1992 and May 28, 1993. In May 1995, United Airlines Pass Through Certificates, Series 1995-A, in an aggregate principal amount of $246,302,000 were issued pursuant to the Basic Agreement and two trust supplements thereto. The following summary of the particular terms of the Certificates offered hereby supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of the Certificates set forth in the Prospectus under the heading "Description of the Certificates". The statements under this caption are a summary and do not purport to be complete. The summary makes use of terms defined in and is qualified in its entirety by reference to all of the provisions of the Basic Agreement, a form of which has been filed as an exhibit to the Registration Statement of which this Prospectus Supplement is a part, and to all of the provisions of the Trust Supplements which, together with the forms of the related Note Purchase Agreements, Indentures, Leases, Trust Agreements and Participation Agreements, will be filed as exhibits to a Current Report on Form 8-K to be filed by United with the Commission in connection with this offering. Except as otherwise indicated, the following summary relates to each of the Trusts and the Certificates issued by each Trust. The terms and conditions governing each of the Trusts will be substantially the same, except that the principal amount, the interest rate, scheduled repayments of principal, and maturity date applicable to the Equipment Notes held by each Trust and the final distribution date applicable to each Trust will differ. Citations to the relevant sections of the Basic Agreement appear below in parentheses unless otherwise indicated. GENERAL The Certificates of each Trust will be issued in fully registered form only. Each Certificate will represent a fractional undivided interest in the Trust created by the Trust Supplement pursuant to which such Certificate is issued. The property of each Trust (the "Trust Property") will include the Equipment Notes held in such Trust, all monies at any time paid thereon, all monies due and to become due thereunder and funds from time to time deposited with the Trustee in accounts relating to such Trust. Each Certificate will represent a pro rata share of the property held in the related Trust and will be issued only in integral multiples of $1,000. (Sections 2.01 and 3.01) The Certificates will be issued pursuant to a book-entry system and will be registered in the name of Cede as the nominee of DTC. No Certificate Owner will be entitled to receive a certificate representing such person's interest in Certificates, except as set forth in the Prospectus under "Description of the Certificates-- Definitive Certificates". Unless and until Definitive Certificates (as defined in the Prospectus) are issued under the limited circumstances described in the Prospectus, all references to actions by Certificateholders shall refer to actions taken by DTC upon instructions from DTC Participants (as defined in the Prospectus), and all references herein to distributions, notices, reports and statements to Certificateholders shall refer, as the case may be, to distributions, notices, reports and statements to DTC or Cede, as the registered holder of the Certificates, or to DTC Participants for distribution to Certificate Owners in accordance with DTC procedures. See "Description of the Certificates--Book-Entry Registration", "--Definitive Certificates", and "--Same-Day Settlement and Payment" in the Prospectus. Interest will be passed through to Certificateholders of each Trust at the applicable rate per annum set forth on the cover page of this Prospectus Supplement, which is calculated on the basis of a 360-day year of twelve 30-day months. The Certificates represent interests in the respective Trusts and all payments and distributions will be made only from the Trust Property. (Section 3.08) The Certificates do not represent an interest in or obligation of United, the Trustees, any of the Loan Trustees or Owner Trustees in their individual capacities, any Owner Participant, or any affiliate of any thereof. S-12 PAYMENTS AND DISTRIBUTIONS Payments of principal, premium, if any, and interest with respect to the Equipment Notes held in each Trust will be distributed by the Trustee to Certificateholders of such Trust on the date receipt of such payment is confirmed, except in certain cases when some or all of such Equipment Notes are in default. See "Description of Certificates--Events of Default and Certain Rights Upon an Event of Default" in the Prospectus. Interest will be payable on the Equipment Notes held in each Trust on the unpaid principal amount thereof on January 30 and July 30 of each year, commencing July 30, 1996. Scheduled principal payments on the Equipment Notes held in each Trust will be passed through to the Certificateholders of such Trust on January 30 or July 30, or both, of certain years, commencing , , in the case of the 1996-A1 Trust, and , , in the case of the 1996-A2 Trust, in accordance with the principal repayment schedule set forth below under "Description of Equipment Notes--General" (such scheduled payments of interest and principal on the Equipment Notes are herein referred to as "Scheduled Payments", and January 30 and July 30 of each year are herein referred to as "Regular Distribution Dates"). See "Description of the Equipment Notes-- General" in this Prospectus Supplement. The Trustee of each Trust will distribute on each Regular Distribution Date to the Certificateholders of such Trust all Scheduled Payments, the receipt of which is confirmed by the Trustee on such Regular Distribution Date. Each Certificateholder of each Trust will be entitled to receive a pro rata share of any distribution in respect of Scheduled Payments of principal and interest made on the Equipment Notes held in such Trust. Each such distribution of Scheduled Payments will be made by the Trustee to the Certificateholders of the applicable Trust of record on the Record Date applicable to such Scheduled Payment subject to certain exceptions. (Sections 4.01 and 4.02) If a Scheduled Payment is not received by the Trustee on a Regular Distribution Date but is received within five days thereafter, it will be distributed on the date of confirmed receipt to such holders of record. If it is received after such five-day period, it will be treated as a Special Payment (as defined below) and distributed as described below. Payments of principal, premium, if any, and interest received by the Trustee on account of the early redemption, if any, of the Equipment Notes held in a Trust, and payments received by the Trustee following a default in respect of Equipment Notes held in a Trust, relating to one or more Aircraft (including payments received by the Trustee on account of the purchase by the related Owner Trustee or Owner Participant of such Equipment Notes or payments received on account of the sale of such Equipment Notes by the Trustee) or Owner Participant (each, a "Special Payment") will be distributed on, in the case of an early redemption or a purchase, the date of such early redemption or purchase (which shall be a Business Day), and otherwise on the Business Day specified for distribution of such Special Payment pursuant to a notice delivered by the Trustee as soon as practicable after the Trustee has confirmed that it has received funds for such Special Payment (each, a "Special Distribution Date"). In the event of redemption or purchase of Equipment Notes held in either Trust, the Trustee will mail notice to the Certificateholders of such Trust not less than 20 days prior to the Special Distribution Date on which such Special Payment is scheduled to be distributed by the Trustee stating such anticipated Special Distribution Date. (Section 4.02) Each distribution of a Special Payment, other than a final distribution, on a Special Distribution Date for any Trust will be made by the Trustee to the Certificateholders of record of such Trust on the Record Date applicable to such Special Payment. See "Description of the Equipment Notes--Redemption" in this Prospectus Supplement and "Description of the Certificates--Events of Default and Certain Rights Upon an Event of Default" in the Prospectus. The Basic Agreement requires that the Trustee establish and maintain, for each Trust and for the benefit of the Certificateholders of such Trust, one or more accounts (the "Certificate Account") for the deposit of payments representing Scheduled Payments on the Equipment Notes held in such Trust. The Basic Agreement also requires that the Trustee establish and maintain, for each Trust and for the benefit of the Certificateholders of such Trust, one or more accounts (the "Special Payments Account") for the deposit of payments representing Special Payments, which account shall be non-interest bearing except in certain circumstances where the Trustee may invest amounts in such account in certain permitted investments. Pursuant to the terms of the Basic Agreement, the Trustee is required to deposit any Scheduled Payments relating to the applicable Trust received by it in the Certificate Account of such Trust and to deposit any S-13 Special Payments so received by it in the Special Payments Account of such Trust. (Section 4.01) All amounts so deposited will be distributed by the Trustee on a Regular Distribution Date or a Special Distribution Date, as appropriate. (Section 4.02) At such time, if any, as the Certificates are issued in the form of Definitive Certificates and not to Cede, as nominee for DTC, distributions by the Trustee from the Certificate Account or the Special Payments Account of each Trust on a Regular Distribution Date or a Special Distribution Date will be made by check mailed to each Certificateholder of record of such Trust on the applicable Record Date at its address appearing on the register maintained with respect to such Trust. (Section 4.02) The final distribution for each Trust, however, will be made only upon presentation and surrender of the Certificates for such Trust at the office or agency of the Trustee specified in the notice given by the Trustee of such final distribution. The Trustee will mail such notice of the final distribution to the Certificateholders of such Trust, specifying the date set for such final distribution and the amount of such distribution. (Section 11.01) See "Description of the Certificates-- Termination of the Trusts" in the Prospectus. If any Regular Distribution Date or Special Distribution Date is not a Business Day, distributions scheduled to be made on such Regular Distribution Date or Special Distribution Date will be made on the next succeeding Business Day without additional interest. (Section 12.10) To the extent that any of the Equipment Notes contemplated to be held in the related Trust are not purchased out of the proceeds from the sale of Certificates on the date of issuance of the Certificates, the Trustee may use the unused portion of the proceeds for the purchase of such Equipment Notes at any time on or prior to March 31, 1996, and pending such purchase the Trustee will hold such proceeds from the sale of Certificates in an escrow account. Such proceeds will be invested, at the direction and risk of, and for the account of, United, in certain specified investments, which may include: (i) obligations of, or guaranteed by, the United States government or agencies thereof, (ii) open market commercial paper of any corporation incorporated under the laws of the United States of America or any state thereof rated at least P-2 or its equivalent by Moody's Investors Service, Inc. or at least A-2 or its equivalent by Standard & Poor's Ratings Services, (iii) certificates of deposit issued by commercial banks organized under the laws of the United States or of any political subdivision thereof having a combined capital and surplus in excess of $500,000,000 which banks or their holding companies have a rating of A or its equivalent by Moody's Investors Service, Inc. or Standard & Poor's Ratings Services; provided, however, that the aggregate amount at any one time so invested in certificates of deposit issued by any one bank shall not exceed 5% of such bank's capital and surplus, (iv) U.S. dollar denominated offshore certificates of deposit issued by, or offshore time deposits with, any commercial bank described in (iii) or any subsidiary thereof and (v) repurchase agreements with any financial institution having combined capital and surplus of at least $500,000,000 with any of the obligations described in (i) through (iv) as collateral; provided that if all of the above investments are unavailable, the entire amounts to be invested may be used to purchase federal funds from an entity described in clause (iii) above; and provided further that no investment shall be eligible as a "specified investment" unless the final maturity date or date of return of such investment is on or before April 20, 1996. Earnings on such investments in the escrow account for each Trust will be paid to United periodically, and United will be responsible for any losses and United will pay to the Trustee on demand any such losses such that the amount of proceeds held in the escrow account shall be sufficient to purchase the Equipment Notes. To the extent that any amount of the proceeds held in the escrow account referred to above is not used to purchase Equipment Notes on or prior to March 31, 1996, an amount equal to the unused proceeds will be distributed by the Trustee to the holders of record of the Certificates on a pro rata basis upon not less than 20 days' prior notice to them as a Special Payment on a Special Distribution Date not later than April 20, 1996, together with interest thereon at a rate equal to the rate applicable to such Certificates, but without premium, and United will pay to the Trustee on such date an amount equal to such interest. (Sections 1.01 and 2.02(b)) In the event of a delayed purchase of Equipment Notes as described above, on July 30, 1996, United will pay to the Trustee of each Trust an amount equal to the interest that would have accrued on any Equipment Notes purchased on a delayed basis by such Trust for the period from the date of the issuance of S-14 the Certificates to, but excluding, the date of the purchase of such Equipment Notes by the Trustee, which amount will be passed through to Certificateholders of such Trust on such date, together with any interest on the Equipment Notes held in such Trust. (Section 2.02(b)) POOL FACTORS Unless there has been an early redemption, purchase, or a default in the payment of principal or interest, in respect of one or more issues of the Equipment Notes held in a Trust, as described in "Description of the Equipment Notes--Redemption" in this Prospectus Supplement and "Description of Certificates--Events of Default and Certain Rights Upon an Event of Default" in the Prospectus, the Pool Factor with respect to the 1996-A1 Trust and 1996-A2 Trust will decline in proportion to the scheduled repayments of principal on the Equipment Notes held in such Trusts as described below in "Description of the Equipment Notes--General". In the event of such redemption, purchase or default, the Pool Factor and the Pool Balance of each Trust so affected will be recomputed after giving effect thereto and notice thereof will be mailed to the Certificateholders of such Trust. Each Trust will have a separate Pool Factor. The "Pool Balance" for each Trust indicates, as of any date, the aggregate unpaid principal amount of the Equipment Notes held in such Trust on such date plus any amounts in respect of principal on such Equipment Notes held by the Trustee and not yet distributed. The Pool Balance for each Trust as of any Regular Distribution Date or Special Distribution Date shall be computed after giving effect to the payment of principal, if any, on the Equipment Notes held in such Trust and the distribution thereof to be made on that date. The "Pool Factor" for each Trust as of any Regular Distribution Date or Special Distribution Date is the quotient (rounded to the seventh decimal place) computed by dividing (i) the Pool Balance by (ii) the aggregate original principal amount of the Equipment Notes held in such Trust. The Pool Factor for each Trust as of any Regular Distribution Date or Special Distribution Date shall be computed after giving effect to the payment of principal, if any, on the Equipment Notes held in such Trust and the distribution thereof to be made on that date. Assuming that no early redemption or purchase, or default, in respect of any Equipment Notes shall have occurred, the Pool Factor for each Trust will initially be 1.0000000; thereafter, the Pool Factor for each Trust will decline as described herein to reflect reductions in the Pool Balance of such Trust. The amount of a Certificateholder's pro rata share of the Pool Balance of a Trust can be determined by multiplying the original principal amount of the holder's Certificate of such Trust by the Pool Factor for such Trust as of the applicable Regular Distribution Date or Special Distribution Date. The Pool Factor and the Pool Balance for each Trust will be mailed to Certificateholders of such Trust on each Regular Distribution Date and Special Distribution Date. S-15 As of the date of sale by the Trustee of the Certificates and assuming that no early redemption or purchase, or default in the payment of principal, in respect of any Equipment Notes shall occur, the Scheduled Payments of principal on the Equipment Notes held in the 1996-A1 Trust and 1996-A2 Trust, and the resulting Pool Factors for such Trusts after taking into account each Scheduled Payment, are set forth below:

S-16 DESCRIPTION OF THE EQUIPMENT NOTES The following summarizes the particular terms and provisions of the Equipment Notes and supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of the Equipment Notes set forth in the Prospectus under the heading "Description of the Equipment Notes." The statements under this caption are summaries and do not purport to be complete. The summaries make use of terms defined in and are qualified in their entirety by reference to all of the provisions of the Equipment Notes, the Note Purchase Agreement, the Indentures, the Leases, the Participation Agreements and the Trust Agreements, the forms of which will be filed as exhibits to a Current Report on Form 8-K to be filed by United with the Commission in connection with this offering. Except as otherwise indicated, the following summaries relate to the Equipment Notes, the Note Purchase Agreement, if any, the Indenture, the Lease, the Participation Agreement and the Trust Agreement relating to each Aircraft. GENERAL The Equipment Notes with respect to each Aircraft will be issued in two series. The Equipment Notes with respect to each Aircraft are to be issued under a separate Indenture between State Street Bank and Trust Company of Connecticut, National Association, as Owner Trustee of a trust for the benefit of the Owner Participant which is the beneficial owner of such Aircraft, and First Security, as Loan Trustee. The Owner Trustee has leased each Aircraft to United pursuant to a separate Lease between the related Owner Trustee and United with respect to such Aircraft and has granted a security interest in such Aircraft and the rentals and other amounts due under the related Lease to the related Loan Trustee as security for the related Equipment Notes. United is obligated to make or cause to be made rental and other payments to the related Loan Trustee on behalf of the related Owner Trustee in amounts that will be at least sufficient to pay when due all payments required to be made on the Equipment Notes issued with respect to such Aircraft. The Equipment Notes are not, however, obligations of, or guaranteed by, United. United's rental obligations under each Lease are general obligations of United. Interest will be payable on the Equipment Notes held in each Trust on the unpaid principal amount thereof on January 30 and July 30 of each year, commencing July 30, 1996, which interest will be passed through to Certificateholders of such Trust on each such date. Interest is calculated on the basis of a 360-day year consisting of twelve 30-day months. The aggregate principal amounts of the Equipment Notes to be issued with respect to each Aircraft, as such Equipment Notes are to be held in each of the Trusts, is as follows:

S-17 The Scheduled Payments of principal on the Equipment Notes to be held in the 1996-A1 Trust and 1996-A2 Trust are as follows: 1996-A1 TRUST % EQUIPMENT NOTES

REGULAR DISTRIBUTION DATES AIRCRAFT NO. 1 AIRCRAFT NO. 2 AGGREGATE TOTAL ------------------ -------------- -------------- --------------- ---------- ---------- ---------- Total....................... ========== ========== ==========
If any date scheduled for any payment of principal, premium, if any, or interest with respect to the Equipment Notes is not a Business Day, such payment will be made on the next succeeding Business Day without any additional interest. REDEMPTION The Equipment Notes issued with respect to each Aircraft are separately subject to redemption or purchase in whole prior to maturity, without the consent of the Trustee, (i) on the Regular Distribution Dates occurring on or after the date specified in the related Lease (the earliest of which for any Aircraft is January 30, 2002) in connection with a voluntary termination by United of the related Lease if such Aircraft has been declared by United to be surplus to its requirements or economically obsolete to it, (ii) on certain Regular Distribution Dates as specified in the related Lease (the earliest of which is July 30, 2008) in connection with a purchase by United of such Aircraft where United does not assume the obligations of the applicable Owner Trustee under the related Indenture, (iii) on any Special Distribution Date occurring on or after February , 2001 in connection with an optional redemption as a part of a refunding or refinancing thereof or (iv) at the option of the applicable Owner Trustee or Owner Participant at any time after one or more Lease Events of Default under the related Lease shall have occurred and be continuing for a period of 180 days or more but less than one year during which period such Equipment Notes shall not have been accelerated, on the Special Distribution Date following notice by such Owner Trustee or Owner Participant of its election to so redeem or purchase such Equipment Notes. The price for the Equipment Notes redeemed under the circumstances set forth above shall be equal to the Redemption Price, plus a premium (as defined below), if any. If the sale of an Aircraft contemplated to occur on a lease termination date is not completed, the corresponding redemption will not take place and any notice of redemption will be deemed revoked. (Indentures, Article 6 and Section 8.03; Leases, Sections 9(b) and 19(b); Participation Agreements, Section 17) S-19 The "premium," if any, with respect to the Equipment Notes to be redeemed or purchased on any redemption or purchase date will be an amount which an independent investment banking institution of national standing selected by United (or, in certain circumstances, the applicable Owner Trustee or Loan Trustee) shall determine to be equal to the excess, if any, of (i) the sum of the present values of all the remaining Scheduled Payments of principal and interest from such redemption date to maturity of such Equipment Notes, discounted semiannually on each January 30 and July 30 at a rate equal to the Treasury Yield (as defined below), based on a 360-day year of twelve 30-day months, over (ii) the aggregate unpaid principal amount of such Equipment Notes plus accrued but unpaid interest on such Equipment Notes (but not any accrued interest in default), provided, however, that, if such redemption or purchase occurs on or after , , in the case of the Equipment Notes held in the 1996-A1 Trust, or , , in the case of Equipment Notes held in the 1996-A2 Trust, the premium shall be zero. (Indentures, Section 6.01(b)) The "Treasury Yield" means, with respect to each Equipment Note to be redeemed or purchased, (x) in the case of an Equipment Note having a maturity less than one year after the applicable redemption or purchase date, the average yield to stated maturity on a government bond equivalent basis of the applicable United States Treasury Bill due the week of the maturity of such Equipment Note or (y) in the case of an Equipment Note having a maturity of one year or more after the applicable redemption or purchase date, the average yield to stated maturity of the most comparable United States Treasury Notes or Bonds as identified by an independent investment banker, corresponding in maturity to the Remaining Weighted Average Life (as defined below) of such Equipment Note (or, if there is no maturity corresponding to such Remaining Weighted Average Life, an interpolation of maturities by such independent investment banker), in each case under (x) and (y) above determined by such independent investment banker based on the average of the yields to stated maturity determined from the bid prices on the fourth Business Day preceding the applicable redemption or purchase date. The "Remaining Weighted Average Life" of such Equipment Note, at the redemption or purchase date of such Equipment Note, shall be the number of years obtained by dividing (a) the sum of the products obtained by multiplying (i) the amount of each then remaining Scheduled Payment of principal, including the payment due on the maturity date of such Equipment Note, by (ii) the number of years (calculated to the nearest one-twelfth) which will elapse between the redemption or purchase date and the Regular Distribution Dates of such Scheduled Payments of principal, by (b) the then outstanding principal amount of such Equipment Note. In addition, the Equipment Notes issued with respect to each Aircraft are separately subject to redemption or purchase prior to maturity, without the consent of the Trustee, at a price equal to the Redemption Price, but without any premium (i) in whole at the option of the applicable Owner Trustee or Owner Participant, at any time after the occurrence and continuation of one or more Lease Events of Default under the related Lease for a period of one year or more during which period such Equipment Notes shall not have been accelerated, (ii) in whole upon the acceleration of such Equipment Notes, (iii) in whole upon an Event of Loss with respect to such Aircraft if United has elected not to replace such Aircraft under the applicable Lease or (iv) with respect to the 777 Aircraft, in part upon an Event of Loss with respect to an Engine under certain circumstances set forth in Section 10(b) of the applicable Lease. (Indentures, Sections 6.01, 6.02 and 8.03) INDENTURE DEFAULTS, NOTICE AND WAIVER Indenture Defaults include: (i) the occurrence of any Lease Event of Default under the applicable Lease, other than the failure to make certain indemnity and certain other payments to the related Owner Trustee or Owner Participant, (ii) failure to pay any interest or principal or premium, if any, when due, continued for S-20 more than 10 days after such amount shall have become due and payable, (iii) failure by the related Owner Trustee, in its individual capacity or as Owner Trustee, as the case may be, or the related Owner Participant to observe or perform in any material respect certain covenants or obligations contained in the applicable Indenture, Participation Agreement or Trust Agreement, or failure by the related Owner Trustee or Owner Participant to observe or perform any other covenant or obligation contained therein, which failure shall have a material adverse effect on the rights and interests of the holders of the Equipment Notes, and in either case, such failure is not remedied within a period of 30 days after notice to the related Owner Trustee and Owner Participant by the related Loan Trustee or the holders of at least 25% in unpaid principal amount of outstanding Equipment Notes issued under such Indenture, (iv) any representation or warranty made by the related Owner Trustee or Owner Participant in the applicable Participation Agreement, Note Purchase Agreement or Indenture, or in any document or certificate furnished to the related Loan Trustee pursuant thereto being incorrect in any material respect as of the date made and such incorrectness shall remain material and continue unremedied for a period of 30 days after notice to such Owner Trustee and Owner Participant by the related Loan Trustee or the holders of at least 25% in unpaid principal amount of outstanding Equipment Notes issued under such Indenture, and (v) the occurrence of certain events of bankruptcy, reorganization or insolvency of the related Owner Participant or Owner Trustee or the property subject to the related Indenture. (Indentures, Section 8.01) There are no cross-default provisions in the Indentures and consequently an Indenture Default under any particular Indenture will not in itself result in an Indenture Default under any other Indenture. In the event United fails to make any semiannual basic rent payment when due, and as long as no other Indenture Defaults (except a Lease Event of Default not involving the nonpayment of money) under the related Indenture shall have occurred and be continuing, within a specified period after such failure, the related Owner Participant or Owner Trustee may furnish to the related Loan Trustee an amount at least equal to the principal and interest then due but unpaid under the related Equipment Notes, varying by Aircraft, together with any interest thereon on account of the delayed payment thereof, in which event such Loan Trustee and the holders of outstanding Equipment Notes issued under such Indenture may not exercise any remedies otherwise available under such Indenture or such Lease as the result of such failure to make such rental payment, unless United has failed to make a basic rent payment when due on the three consecutive immediately preceding semiannual basic rent payment dates or on any six or more previous semiannual basic rent payment dates. The related Owner Participant or Owner Trustee may also cure any other default by United in the performance of its obligations under the applicable Lease that can be cured by the payment of money. (Indentures, Section 8.03(e)(i)) Each Indenture provides that the Loan Trustee thereunder shall, after the occurrence of any event known to it to be an Indenture Default, promptly send written notice thereof to United, the Owner Trustee and the applicable Owner Participant, and within 90 days after the occurrence thereof, if such Indenture Default remains uncured, mail notice thereof to the holders of outstanding Equipment Notes issued under such Indenture, but such Loan Trustee may withhold such notice, except in the case of a default in the payment of the principal, interest or premium, if any, with respect to any such Equipment Notes, if it in good faith determines that withholding such notice is in the interest of such holders. (Indentures, Section 9.05) The holders of at least a majority in principal amount of the outstanding Equipment Notes issued with respect to any Aircraft may, by notice to the Loan Trustee, waive on behalf of all of the holders of such Equipment Notes any existing event of default or default and its consequences under the Indenture with respect to such Aircraft, except a default in the payment of the principal or interest on any such Equipment Note or in respect of any covenant or provision of such Indenture that cannot be modified or amended without the consent of each holder of an Equipment Note affected thereby. (Indentures, Sections 8.05 and 11.02) United is required to furnish annually to the Trustee a statement as to the fulfillment of its covenants under the Basic Agreement, and to the Loan Trustees a statement as to the fulfillment of its covenants under the Leases during the preceding year. (Basic Agreement, Section 8.04(d); Leases, Section 16(c)) S-21 REMEDIES If an Indenture Default shall occur and be continuing under an Indenture, the Loan Trustee thereunder or the holders of not less than 25% in unpaid principal amount of the Equipment Notes outstanding under such Indenture may declare the principal of all such Equipment Notes issued thereunder immediately due and payable. The holders of a majority in unpaid principal amount of Equipment Notes outstanding under such Indenture may annul any such declaration by such Loan Trustee or by the holders at any time prior to the sale of the related Aircraft after such an Indenture Default if (i) there has been paid to or deposited with such Loan Trustee an amount sufficient to pay all overdue installments of principal and interest on any such Equipment Notes that have become due otherwise than by such declaration of acceleration and any interest thereon and overdue installments of interest and certain expenses, (ii) such annulment would not conflict with any judgment or decree and (iii) all other existing Indenture Defaults under such Indenture have been cured or waived (other than nonpayment of principal of, or interest on, the Equipment Notes that has become due solely because of such acceleration). (Indentures, Section 8.02) Each Indenture provides that if an Indenture Default has occurred and is continuing, the Loan Trustee thereunder may exercise certain rights or remedies available to it under applicable law, including (if a Lease Event of Default under the related Lease has occurred and is continuing) one or more of the remedies with respect to the related Aircraft afforded to the applicable Owner Trustee by the related Lease for Lease Events of Default thereunder. Such Loan Trustee's right to exercise remedies under such Indenture is subject, in certain circumstances, to its having exercised or its concurrent exercise of certain remedies under Section 15 of the related Lease with respect to the related Aircraft, provided that the requirement to exercise such remedies under such Lease shall not apply in circumstances where such exercise has been involuntarily stayed or prohibited by applicable law or court order for a continuous period in excess of 60 days or such other period as may be specified in section 1110(a)(1)(A) of the Bankruptcy Code (as defined below) (plus an additional period, if any, resulting from (i) United or its trustee in bankruptcy in such proceeding assuming, or agreeing to perform its obligations under, such Lease with the approval of the applicable court or such Loan Trustee's consent to an extension of such period or (ii) such Loan Trustee's failure to give any requisite notice). See "The Leases--Events of Default" in this Prospectus Supplement. Such remedies may be exercised by such Loan Trustee to the exclusion of such Owner Trustee and, subject to the terms of such Lease, United. Any Aircraft sold in the exercise of such remedies will be free and clear of any rights of those parties, including the rights of United under the related Lease; provided that no exercise of any remedies by a Loan Trustee may affect the rights of United under the related Lease unless a Lease Event of Default thereunder has occurred and is continuing. (Indentures, Section 8.03) Section 1110 of title 11 of the United States Code (the "Bankruptcy Code") provides in part that the right of a lessor of aircraft, aircraft engines, propellers, appliances or spare parts, as defined in Section 40102 of the Aviation Act, that are subject to a lease to an air carrier that is a citizen of the United States (as defined in Section 40102 of the Aviation Act) operating under an air carrier operating certificate issued by the Secretary of Transportation pursuant to Chapter 447 of the Aviation Act for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo to take possession of such equipment in compliance with the provisions of such lease is not affected by (i) the automatic stay provision of the Bankruptcy Code, which provision enjoins repossessions by creditors for the duration of the reorganization period, (ii) the provision of the Bankruptcy Code allowing the debtor in possession and/or the bankruptcy trustee to use property of the bankruptcy estate during the reorganization period, (iii) the provision of the Bankruptcy Code allowing the proponent of a plan of reorganization to confirm such plan by imposing the plan upon a class of claims or interests that has not accepted or is impaired by such plan and (iv) any power of the bankruptcy court to enjoin a repossession. Section 1110 provides, however, that the right of a lessor to take possession of an aircraft in the event of an event of default may not be exercised for 60 days following the date of the order for relief (unless specifically permitted by the bankruptcy court) and may not be exercised at all if, within such 60-day period, the debtor in possession and/or the bankruptcy trustee agrees to perform the debtor's obligations that become due on or after such date and cures all existing defaults (other than defaults resulting solely from the financial condition, bankruptcy, insolvency or reorganization of the debtor). S-22 United has been advised by its counsel, Vedder, Price, Kaufman & Kammholz, that in its opinion each Owner Trustee, as lessor under the related Lease, and the related Loan Trustee, as assignee of such Owner Trustee's rights under such Lease pursuant to the related Indenture, would be entitled to the benefits of section 1110 of the Bankruptcy Code with respect to the Aircraft initially delivered under such Lease and subjected to the related Indenture. The opinion of Vedder, Price, Kaufman & Kammholz does not address the possible replacement of an Aircraft after an Event of Loss in the future, the consummation of which is conditioned upon the contemporaneous delivery of an opinion of counsel to the effect that the Loan Trustee shall continue to be entitled to the benefits of section 1110 with respect to such replacement. See "The Leases--Events of Loss" in this Prospectus Supplement. The holders of a majority in principal amount of the Equipment Notes outstanding under any Indenture may direct the time, method and place of conducting any proceeding for any remedy available to the related Loan Trustee or of exercising any trust or power conferred on such Loan Trustee but in such event such Loan Trustee shall be entitled to be indemnified by the holders of such Equipment Notes before proceeding so to act and such Loan Trustee may not be held liable for any such action taken in good faith. The Loan Trustee may, in certain circumstances, refuse to follow such a direction. (Indentures, Sections 8.06, 9.01 and 9.02) The right of any holder of Equipment Notes to institute action for any remedy under the Indenture pursuant to which such Equipment Notes are issued (except the right to enforce payment of the principal, interest and premium, if any, with respect to its Equipment Notes when due) is subject to certain conditions precedent, including a request to the related Loan Trustee by the holders of not less than 25% in principal amount of such Equipment Notes outstanding to take action and an offer to such Loan Trustee of satisfactory indemnification against liabilities incurred by it in so doing. (Indentures, Sections 8.07 and 8.08) If an Indenture Default occurs and is continuing, any sums held or received by the related Loan Trustee may be applied to reimburse such Loan Trustee for any tax, expense or other loss incurred by it and to pay any other amounts due to such Loan Trustee prior to any payments to holders of the Equipment Notes issued under such Indenture. (Indentures, Section 3.05) In the event of insolvency proceedings involving an Owner Participant, the related Aircraft, Lease and Equipment Notes might become part of such insolvency proceeding. In such event, payments under such Lease or on such Equipment Notes might be interrupted and the ability of the related Loan Trustee to exercise its remedies under the applicable Indenture might be restricted, although such Loan Trustee would retain its status as a secured creditor in respect of such Lease and Aircraft. MODIFICATION OF INDENTURES, LEASES AND PARTICIPATION AGREEMENTS Without the consent of holders of a majority in principal amount of the Equipment Notes outstanding under any Indenture, the provisions of such Indenture and the Lease and the Participation Agreement corresponding thereto may not be amended or modified, except to the extent indicated below. Certain provisions of any Indenture, and of the Lease, the Trust Agreement and the Participation Agreement corresponding thereto, may be modified by the parties thereto without the consent of any holders of the Equipment Notes outstanding under such Indenture. In the case of each Lease, such provisions include, among others, provisions relating to (i) rental payments and other payments, except to the extent that any such modification would cause the amount of such payments to be insufficient to pay the principal, interest and premium, if any, with respect to the related Equipment Notes, (ii) the return to the Owner Trustee thereunder of the related Aircraft at the end of the term of such Lease and (iii) the renewal of such Lease and the option of United at the end of the term of such Lease to purchase the related Aircraft. (Indentures, Sections 11.01 and 11.06) S-23 Without the consent of the holder of each Equipment Note outstanding under any Indenture affected thereby, no amendment or modification of such Indenture may (i) reduce the principal amount, premium, if any, or any payment of interest due on any Equipment Note issued thereunder, (ii) change the date on which any payment of principal, premium, if any, or interest is due or payable on any Equipment Note issued thereunder, (iii) create any lien with respect to the property subject to the lien of such Indenture ranking prior to or on a parity with the lien created by such Indenture or deprive any holder of an Equipment Note issued thereunder of the lien of such Indenture upon the property subject thereto, (iv) reduce the percentage in principal amount of outstanding Equipment Notes issued thereunder necessary to modify or amend any provision of such Indenture or to waive compliance therewith or (v) modify any of the provisions relating to the rights of holders in respect of the waiver of defaults or events of default or receipt of payment. (Indentures, Section 11.02) THE LEASES Each Aircraft has been leased by the related Owner Trustee under the related Lease to United. Term and Rentals. Each Aircraft has been leased separately by the related Owner Trustee to United for a term commencing on the delivery date thereof to the related Owner Trustee and expiring on a date not earlier than the latest maturity date of the related Equipment Notes, unless previously terminated as permitted by the related Lease. The semiannual basic rent payments under each Lease are payable by United on each January 30 and July 30 (or, if such day is not a Business Day, on the next succeeding Business Day) and has been assigned by the Owner Trustee under the corresponding Indenture to provide the funds necessary to make payments of principal and interest due from the Owner Trustee on the Equipment Notes issued under the Indenture corresponding to such Lease. In certain cases, the semiannual basic rent payments under the Leases will be adjusted, but each Lease provides that under no circumstances will rent payments by United be less than the scheduled payments on the related Equipment Notes. The balance of any such semiannual basic rent payment under the Leases, after payment of amounts due on the Equipment Notes issued under the Indenture corresponding to such Lease and any amounts due to the applicable Loan Trustee as compensation or indemnification, will be paid over to the applicable Owner Participant. United's obligation to pay rent and to cause other payments to be made under the Leases is a general obligation of United. (Leases, Section 3; Indentures, Section 3.03) Net Lease. United's obligations in respect of each of the Aircraft are those of a lessee under a "net lease". Accordingly, United is obligated, at its expense, to cause each Aircraft to be duly registered in the name of the applicable Owner Trustee, to pay all costs of operating each Aircraft and to maintain, service, repair and overhaul (or cause to be maintained, serviced, repaired and overhauled) each Aircraft (i) so as to keep it in at least as good operating condition as when delivered to United, ordinary wear and tear excepted, and in such condition as may be necessary to enable the airworthiness certification thereof to be maintained in good standing at all times (other than during temporary periods of storage in accordance with applicable regulations) under the Aviation Act except when all of United's aircraft of the same model as such Aircraft registered in the United States have been grounded by the Federal Aviation Administration (unless, with respect to the 747 Aircraft, such grounding was caused by United's failure to maintain, service, repair or overhaul the 747 Aircraft in accordance with the terms of the related Lease) or, if the Aircraft is registered in a foreign jurisdiction, except when all United's aircraft of the same model as such Aircraft registered in such foreign jurisdiction have been grounded by the aeronautical authority in such jurisdiction (unless, with respect to the 747 Aircraft, such grounding was caused by United's failure to maintain, service, repair or overhaul the 747 Aircraft in accordance with the terms of the related Lease) and (ii) in substantially the same manner in which United, or, in the event of a sublease, such sublessee, maintains, services, repairs or overhauls similar aircraft operated by United (or such sublessee) in similar circumstances and without in any way discriminating against such Aircraft, whether by reason of its leased status or otherwise (or, in the case of the 777 Aircraft, in such other manner as has been approved by the related Owner Participant). (Leases, Section 7(a)) United will, at its expense, replace or cause to be replaced all parts (other than certain severable parts added at the option of United and obsolete or unsuitable parts that United is permitted to remove to the extent described below) that may from time to time be incorporated or installed in or attached to either Aircraft or which have been removed therefrom but where S-24 title remains vested in the related Owner Trustee in accordance with the terms of the related Lease and that may become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or rendered permanently unfit for use. (Leases, Section 8(a)) United or any sublessee has the right, at its own expense, to make such alterations, modifications and additions (including removal of parts which United or any sublessee claims to be obsolete or no longer suitable or appropriate for use) with respect to each Aircraft as United or such sublessee deems desirable in the proper conduct of its business, provided that no such alteration, modification, removal or addition shall diminish (or, in the case of the 747 Aircraft, shall materially diminish) the value or utility (or, in the case of the 777 Aircraft, with respect to the related airframe and Engines, remaining useful life) of such Aircraft or impair the condition or airworthiness thereof. In addition to the foregoing, the value (but not the utility, or, in the case of the 777 Aircraft, the condition, airworthiness or remaining useful life) of an Aircraft may be reduced by the value of parts that United deems obsolete or no longer suitable or appropriate, provided that the aggregate value of all such parts removed from an Aircraft and not replaced shall not exceed $600,000 in the case of the 747 Aircraft and $700,000 in the case of the 777 Aircraft. (Leases, Section 8(c)) Registration, Possession, Sublease and Transfer. United may, under certain circumstances, after the date specified in the related Lease (the earliest of which for either Aircraft is January 1, 2002) register an Aircraft in certain jurisdictions outside the United States. United may, subject to certain limitations, sublease an Aircraft to any United States certificated air carrier or to certain foreign air carriers (such United States and foreign air carriers being the "Permitted Air Carriers") or to any other entity approved by the related Owner Participant, so long as the term of the sublease does not extend beyond the end of the basic term or any renewal term (or, in the case of the 777 Aircraft, beyond the date three months prior to the end of the basic term or any renewal term) then in effect under the Lease to which such Aircraft is subject unless United shall have irrevocably committed to purchase such Aircraft or renew such Lease in accordance with the terms thereof at the end of the basic term or renewal term, as the case may be, to a date beyond the term of the sublease (or, in the case of the 777 Aircraft, to a date at least three months beyond the term of the sublease). In addition, subject to certain limitations, United may transfer possession of an Aircraft other than by sublease, including transfers in connection with normal interchange or pooling arrangements (in the case of the 777 Aircraft, with Permitted Air Carriers or other carriers approved by the Owner Trustee), "wet leases", transfers to the United States of America or any instrumentality or agency thereof and transfers in connection with maintenance or modifications. If an Aircraft is subleased or the possession thereof is otherwise transferred, such Aircraft will remain subject to the related Lease and to the lien of the related Indenture. (Leases, Sections 7(a) and 7(b)) An Aircraft may be operated by United or under sublease or interchange arrangements or may be registered in countries that are not parties to the Geneva Convention for the International Recognition of Rights in Aircraft, and the extent to which the related Loan Trustee's security interest would be recognized in such Aircraft if located in such countries is uncertain. Liens. United will maintain each Aircraft free of any liens, other than the rights of the applicable Owner Participant, Owner Trustee, Loan Trustee, the holders of the related Equipment Notes and United arising under the Trust Agreement, the Lease, the Indenture, the Participation Agreement or other documents related thereto, and other than certain limited liens permitted under such related Lease and related Indenture, including liens for taxes either not yet due and payable or being contested in good faith by appropriate proceedings so long as such proceedings do not involve any material risk of the sale, forfeiture or loss of such Aircraft or any interest therein; materialmen's, mechanics' and other similar liens arising in the ordinary course of business securing obligations that are either not overdue for more than 30 days or being contested in good faith by appropriate proceedings so long as during such period there is not, nor do such proceedings involve, any material risk of the sale, forfeiture or loss of such Aircraft or any interest therein; judgment liens, unless the judgment secured shall not, within 45 (or, with respect to the 777 Aircraft, 30) days after the entry thereof, have been discharged, vacated, reversed or execution thereof stayed pending appeal (and, with respect to the 747 Aircraft, so long as during such 45-day period there exists no material risk of the sale, forfeiture or loss of such Aircraft or any interest therein); or liens with respect to which United or any sublessee shall have posted a bond or other security; and certain liens required to be removed by the related Owner Trustee or Owner Participant. (Leases, Section 6; Participation Agreements, Section 8(g)) S-25 Insurance. United will, at its or any sublessee's expense, maintain or cause to be maintained all-risk aircraft hull insurance covering each Aircraft and fire and extended coverage (including war risk, governmental confiscation and hijacking insurance, if and to the extent the same is maintained by United or any sublessee with respect to other aircraft owned or leased, and operated by United or such sublessee on the same routes) at all times in an amount not less than the stipulated loss value of such Aircraft (which will be an amount at least equal to the aggregate unpaid principal of, together with all unpaid interest accrued on, the outstanding Equipment Notes related to such Aircraft). During any period when an Aircraft is on the ground and not in operation, United may carry or cause to be carried in lieu of the insurance required by the previous sentence, insurance otherwise conforming with the provisions of said sentence except that the scope of the risks covered and the type of insurance shall be the same as are from time to time applicable to aircraft owned or leased by United of the same type as such Aircraft similarly on the ground and not in operation, in an amount at least equal to the stipulated loss value of such Aircraft. All policies covering loss of or damage to an Aircraft shall be made payable to the applicable Loan Trustee for any loss in excess of that certain amount specified in the applicable Lease, the highest of which under either Lease is $4,000,000. United may self-insure a portion of these risks, but in no case will the self-insurance with respect to all of the aircraft in United's fleet (including the Aircraft) exceed, for any calendar year, the lesser of 50% of the highest replacement value of any single aircraft in United's fleet or 1 1/2% of the average aggregate insurable value (during the preceding calendar year) of all aircraft on which United carries insurance. In addition, United will, at its or any sublessee's expense, carry or cause to be carried comprehensive airline liability (including, without limitation, passenger, contractual, bodily injury and property damage liability) insurance (exclusive of manufacturer's product liability insurance) and cargo liability insurance with respect to each Aircraft (i) in amounts that are not less than the greater of the comprehensive airline liability insurance as is from time to time applicable to aircraft owned or leased, and operated by United of the same type as such Aircraft, and not less than $450,000,000 per occurrence, varying by Aircraft, and (ii) of the types and covering the same risks as are from time to time applicable to aircraft owned or leased, and operated, by United of the same type as such Aircraft and which is maintained in effect with insurers of recognized reputation and responsibility, provided that United need not maintain cargo liability insurance, or may maintain such insurance in an amount less than that specified above for the respective Aircraft as long as the amount of cargo liability insurance, if any, maintained with respect to such Aircraft is the same as the cargo liability insurance, if any, maintained for other aircraft of the same model as such Aircraft owned or leased, and operated by United. During any period when an Aircraft is on the ground and not in operation, United may carry or cause to be carried in lieu of the insurance required by the previous sentence, insurance otherwise conforming with the provisions of said sentence except that the amounts of coverage shall not be required to exceed the amounts of comprehensive airline liability insurance, and the scope of risks covered and type of insurance shall be the same, as are from time to time applicable to aircraft owned or leased by United of the same type as such Aircraft similarly on the ground and not in operation. United may also self-insure a portion of these risks subject to the same limitations described above for insurance for risks of loss of or damage to the Aircraft. The Trustee, each related Loan Trustee, Owner Participant and Owner Trustee, in its individual capacity and as owner of the Aircraft, and United will be named as insured parties under all insurance policies required with respect to the related Aircraft. In addition, the insurance policies maintained under the Lease with respect to each Aircraft will provide that, in respect of the respective interests of the Trustee, the Loan Trustee, the Owner Participant and the Owner Trustee relating to such Aircraft, the insurance shall not be invalidated by any action or inaction of United or any sublessee or any other entity and shall insure the respective interests of the Trustee, the Loan Trustee, the Owner Participant and the Owner Trustee relating to such Aircraft, as they appear, regardless of any breach or violation of any warranty, declaration or condition contained in such policies by United (or any sublessee or any other entity). Subject to certain limited exceptions, United may not operate or permit any sublessee or any other entity to operate either Aircraft in or to any area excluded from coverage by any insurance required by the related Lease (or, in the case of the 777 Aircraft, to a country with which the United States does not have diplomatic relations) unless the United States government or any agency or instrumentality thereof provides indemnification or insurance in lieu of such insurance coverage. (Leases, Sections 7(a) and 11) S-26 Termination. Unless one or more of certain defaults or Lease Events of Default shall have occurred and be continuing, United may terminate the related Lease on the third Business Day prior to the Regular Distribution Dates occurring on or after the date specified in the related Lease (the earliest of which is December 31, 2001) if it shall have determined that such Aircraft is surplus to its requirements or economically obsolete to it. United is required to give notice of its intention to exercise its right of termination described in this paragraph at least 120 days, varying by Aircraft, prior to the proposed date of termination (which notice may be withdrawn in certain circumstances up to 30 days and not more than 360 days prior to such proposed date). In the event that the applicable Owner Trustee elects to sell such Aircraft, United shall use reasonable efforts to obtain bids for such Aircraft as an agent for such Owner Trustee; the applicable Owner Participant may submit bids for such Aircraft. The applicable Owner Trustee shall sell such Aircraft on the date of termination to the highest cash bidder; if such sale occurs, the Equipment Notes related thereto will be redeemed as described herein. The net proceeds of such sale shall be payable to the applicable Owner Trustee. If the net proceeds to be received from such sale are less than the termination value for such Aircraft, United shall pay to the applicable Owner Trustee an amount equal to the difference between such net proceeds and termination value, together with certain other amounts. All funds to be paid to or deposited with the applicable Owner Trustee as described in this paragraph shall, so long as the related Indenture shall not have been discharged, be deposited directly with the applicable Loan Trustee. Upon receipt of the termination value for such Aircraft, together with certain additional amounts and together with all accrued and unpaid interest thereon to the date of the related redemption and an amount equal to the premium, if any, payable on such date of redemption, the lien of the related Indenture shall be released and the related Lease shall terminate with respect to such Aircraft, and the obligation of United thereafter to make scheduled rent payments with respect thereto shall cease. However, certain payment obligations of United shall survive the termination of the Lease. Amounts in excess of the aggregate payments to be made in connection with the redemption of Equipment Notes issued with respect to such Aircraft will be distributed by the Loan Trustee related thereto to the applicable Owner Trustee for distribution in accordance with the terms of the related Lease, Participation Agreement and Trust Agreement. In the event such Aircraft is not sold by the proposed termination date, such Lease, including all of United's obligations thereunder, shall continue in effect, and the Equipment Notes related thereto will not be redeemed. (Leases, Sections 9(b) and 9(c); Indentures, Sections 3.02, 6.01(b) and 13.01) The related Owner Trustee has the option in certain circumstances to retain title to the related Aircraft in the event United has given a notice of termination under the related Lease. In such event, such Owner Trustee shall pay, or cause to be paid, to the applicable Loan Trustee funds in an amount necessary to redeem the outstanding Equipment Notes issued with respect to such Aircraft determined in accordance with the preceding paragraph (other than unpaid basic rent and supplemental rent due on or prior to the proposed redemption date (other than basic rent payable in advance on such redemption date) and amounts payable in respect of any premium on such Equipment Notes, which amounts shall be payable by United). In the event all such amounts are not paid to such Loan Trustee, such Lease will not terminate, and the Equipment Notes related thereto will not be redeemed. (Leases, Section 9) Renewal and Purchase Options. At the end of the term of each Lease after final maturity of the Equipment Notes issued with respect thereto, in the absence of certain defaults or any Lease Event of Default thereunder, United will have certain options to renew such Lease for additional limited periods. In addition, United will have the right at the end of the term of such Lease to purchase the Aircraft subject thereto for an amount to be calculated in accordance with the terms of such Lease. (Leases, Section 19) United will also have the option, exercisable upon 120 days to 360 days' written notice, varying by Aircraft, to purchase either Aircraft on certain specified dates, the earliest of which is July 30, 2008. In the event United exercises such an option, the purchase price therefor shall be calculated in accordance with the provisions of the Lease related thereto, but in any event shall be sufficient to pay the redemption price of the S-27 related Equipment Notes and, upon receipt by the related Loan Trustee of such redemption price, United shall acquire the Aircraft free of the lien of such Indenture, unless United chooses to assume on a full recourse basis all of such Owner Trustee's obligations in respect of the related Equipment Notes and acquires the Aircraft subject to the lien of the related Indenture. See "Description of the Equipment Notes--Assumption of Obligations by United" in this Prospectus Supplement. (Leases, Section 19; Indentures, Section 7.03; Participation Agreements, Section 8(r) with respect to the 747 Aircraft and Section 8(l) with respect to the 777 Aircraft) Events of Loss. If an Event of Loss occurs with respect to an Aircraft, United shall either pay to the applicable Owner Trustee the stipulated loss value of such Aircraft, together with certain additional amounts, or, unless certain defaults or any Lease Event of Default shall have occurred and be continuing, replace such Aircraft. In the event United elects to replace such Aircraft, it must do so on or before the Business Day next succeeding the 100th day following the date of occurrence of such Event of Loss with an aircraft of the same make and model or an improved model, having a value, utility and remaining useful life at least equal to, and in as good operating condition as, the Aircraft subject to the Event of Loss, assuming for this purpose that such Aircraft had been maintained in accordance with the related Lease immediately prior to the occurrence of the Event of Loss. If United pays the stipulated loss value for such Aircraft, together with certain additional amounts, which in all circumstances will be at least sufficient to pay in full as of the date of payment thereof the redemption price of the related Equipment Notes, the lien of the Indenture and the Lease relating to such Aircraft shall terminate with respect to such Aircraft and the obligation of United thereafter to make the scheduled rent payments with respect thereto shall cease. The stipulated loss value and other payments made by United shall be deposited with the applicable Loan Trustee. Amounts in excess of the redemption price of the Equipment Notes issued with respect to such Aircraft will be distributed by such Loan Trustee to the applicable Owner Trustee in accordance with the terms of the applicable Lease, Trust Agreement and Participation Agreement. (Leases, Section 10(a); Indentures, Sections 3.02 and 6.01) If an Event of Loss occurs with respect to an Engine alone, United shall, within 45 days after the occurrence of such Event of Loss, replace such Engine with another engine of the same or another manufacturer and suitable for installation and use on the Aircraft, and having a value and utility at least equal to, and in as good operating condition (and, with respect to the 777 Aircraft, have an equivalent or greater useful remaining life) as the engine subject to the Event of Loss, assuming for this purpose that such Engine had been maintained in accordance with the related Lease immediately prior to the occurrence of such Event of Loss; provided that, with respect to the 777 Aircraft, under certain circumstances, United shall pay stipulated loss value with respect to such Engine, together with certain additional amounts, which in all circumstances will be at least sufficient to pay in full the redemption price with respect to that portion of the Equipment Notes relating to such Engine and, in such event, the lien of the Indenture and the Lease relating to such Engine shall terminate with respect to such Engine and United shall only be obligated to return the related Aircraft with any Engine for which United has not paid the stipulated loss value described above. (Leases, Section 10(b); Indentures, Sections 6.01 and 13.01) An Event of Loss with respect to an Aircraft or any Engine relating thereto means any of the following events with respect to such property: (i) loss of such property or the use thereof due to destruction of or damage to such property which renders repair uneconomic or which renders such property permanently unfit for normal use by United for any reason whatsoever; (ii) any damage to such property which results in an insurance settlement with respect to such property on the basis of a total loss or a constructive or compromised total loss; (iii) the theft or disappearance of such property for a period of, in the case of the 747 Aircraft, 90 consecutive days or, in the case of the 777 Aircraft, 30 consecutive days or, if earlier, until the end of the applicable Lease term (or, in the case of the 777 Aircraft, when United shall no longer be diligently attempting to locate and pursue the return of such property); (iv) the condemnation, confiscation or seizure of, or requisition or taking of title to, or use of, such property by any governmental or purported governmental authority (other than a requisition for use by certain permitted governments or any agency or instrumentality thereof), which in the case of any event referred to in this clause (iv) shall have resulted in a loss of title to, or possession of, such property by United for a period in excess of 90 consecutive days (except that, in the case S-28 of a loss of title relating to the 777 Aircraft, such period shall be in excess of 45 consecutive days) or, if earlier, until the end of the applicable Lease term; (v) as a result of any law, rule, regulation, order or other action by the Federal Aviation Administration or other governmental body of the government of registry of such Aircraft having jurisdiction, use of such property in the normal course of the business of air transportation shall have been prohibited for a period in excess of, in the case of the 747 Aircraft, 180 consecutive days or, in the case of the 777 Aircraft, 120 consecutive days or, if earlier, until the end of the term of the Lease in effect with respect to such Aircraft unless United, prior to the expiration of such period, shall have undertaken and shall be diligently carrying forward all steps which are necessary or desirable to permit the normal use of such property by United (but, with respect to the 777 Aircraft, in any event if such use shall have been prohibited for a period of one year) and, with respect to the 747 Aircraft, (a) such prohibition is applicable to United's entire fleet of aircraft of the same model as the Aircraft registered in the same country and (b) United, within one year from the time of such prohibition, shall have conformed at least one such aircraft in its fleet to the requirements of such law, rule, regulation, order or other action and commenced regular commercial use of the same in such jurisdiction; (vi) the requisition of such property for use by the United States government or any government of registry of the Aircraft or any agency or instrumentality thereof, which shall have occurred during the term of the Lease in effect with respect to such property and, with respect to a requisition by the United States government or any agency or instrumentality thereof, shall have continued beyond the term (or, with respect to the 777 Aircraft, shall have continued for 30 days beyond the term) of the Lease in effect with respect to such property, and the related Owner Trustee shall not have furnished the written notice specified in such Lease or, with respect to any government of registry other than the United States or any agency or instrumentality thereof, shall have continued for more than two years (or, if earlier, until the end of the applicable Lease term); (vii) any divestiture of title to an Engine treated as an Event of Loss pursuant to the Lease in effect with respect to such Aircraft; or (viii) with respect to the 747 Aircraft, the operation of or location of the Aircraft, while under requisition for use by any government, in any area excluded from coverage by any insurance policy in effect with respect to the Aircraft required by the terms of the applicable Lease, unless in the case of a requisition by certain permitted governments or any agency or instrumentality thereof, Lessee shall have obtained an indemnity in lieu thereof from such government. (Leases, Section 1) Events of Default. Events of Default under the Leases (each, a "Lease Event of Default") include, among other things: (i) failure by United to make any payment of basic rent, termination value, stipulated loss value or premium within 10 days after the same shall have become due; (ii) failure by United to make any payment of supplemental rent not specified in clause (i) after the same shall have become due and such failure shall continue for 15 days after receipt of written demand therefor; (iii) failure by United to carry and maintain or cause to be carried or maintained insurance or, in certain instances, government indemnities, on or with respect to the Aircraft subject to such Lease in accordance with the provisions of the applicable Lease; (iv) failure by United to perform or observe (or cause to be performed or observed) in any material respect any other covenant or agreement to be performed or observed by it under such Lease or the related Participation Agreement or Indenture, and such failure shall continue for a period of 30 days after written notice by the applicable Owner Trustee or Loan Trustee, provided, however, that if United shall have undertaken to cure such failure (except that, with respect to the 777 Aircraft, United shall have the right to cure only certain of such failures) and, notwithstanding the reasonable diligence of United in attempting to cure such failure, such failure is not cured within said 30-day period but is curable with future due diligence, there shall exist no Lease Event of Default so long as United is proceeding with due diligence to cure such failure and such failure is in fact cured within 180 days (and, with respect to the 777 Aircraft, provided further that such failure to cure shall not constitute a Lease Event of Default upon the satisfaction of certain conditions, including (A) the provision by United of an officer's certificate with respect to the program and timetable for curing such failure, (B) in the event the estimated costs to cure such failure equal or exceed $2,000,000, the establishment of a reserve account for such amounts and (C) such failure is cured within one full year after such 180-day period); (v) any representation or warranty made by United in such Lease or the related Participation Agreement or in any document or certificate furnished by United in connection therewith or pursuant thereto (except for certain representations and warranties relating to the corresponding tax indemnity agreement) S-29 shall be incorrect in any material respect at the time made and shall remain material at the time in question and shall continue uncured for a period of 30 days after receipt by United of written notice from the applicable Owner Trustee or Loan Trustee (or, with respect to the 777 Aircraft, 30 days after the earlier of (A) receipt by United of written notice from the applicable Owner Trustee or Loan Trustee or (B) knowledge of such incorrectness by a responsible finance officer of United); and (vi) the occurrence of certain events of bankruptcy, reorganization or insolvency of United. (Leases, Section 14) If a Lease Event of Default has occurred and is continuing, and the applicable Lease has been declared to be in default, the applicable Loan Trustee may, subject to the terms of the applicable Indenture, exercise one or more of the remedies provided in such Lease with respect to the related Aircraft. These remedies include the right to repossess and use or operate such Aircraft, to sell or re-lease such Aircraft free and clear of United's rights and retain the proceeds and to require United to pay as liquidated damages any unpaid basic rent plus an amount equal to, at such Loan Trustee's option, any of (i) an amount equal to the excess of the aggregate unpaid basic rent (discounted to present value) over the aggregate fair market rental value (discounted to present value) of the Aircraft for the remainder of the applicable Lease term, (ii) an amount equal to the excess of the stipulated loss value of the relevant Aircraft over the fair market sales value of such Aircraft or (iii) if such Aircraft has been sold, any unpaid basic rent with respect to the Aircraft plus the amount of any deficiency between the net proceeds of such sale and the stipulated loss value of the Aircraft. (Leases, Section 15; Indentures, Section 8.03) Notwithstanding that a Lease Event of Default has occurred and is continuing, the applicable Loan Trustee may not, without the consent of the related Owner Trustee, enter into any amendment of the provisions of such Lease relating to, among other things, the timing and amount of payments by United under such Lease, defaults under such Lease or maintenance of insurance on, modifications or additions to, or sublease, registration, maintenance, operation, return, inspection or purchase of, such Aircraft. (Indentures, Section 11.06) THE PARTICIPATION AGREEMENTS Each Participation Agreement provides that United is required to indemnify the Trustee, the respective Loan Trustee, Owner Participant and Owner Trustee for certain losses and claims and for certain other matters. (Participation Agreements, Section 7(c)). Subject to certain restrictions, each Owner Participant may transfer its interest in the related Aircraft. (Participation Agreements, Section 8(l) with respect to the 747 Aircraft and Section 8(h) with respect to the 777 Aircraft) DEFEASANCE OF THE INDENTURES AND THE EQUIPMENT NOTES IN CERTAIN CIRCUMSTANCES Each Indenture provides that the obligations thereunder of the related Loan Trustee and Owner Trustee shall be deemed to have been discharged and paid in full (except for certain obligations, including the obligations to register the transfer or exchange of Equipment Notes, to replace stolen, lost, destroyed or mutilated Equipment Notes and to maintain paying agencies and hold money for payment in trust) on the 91st day after the date of irrevocable deposit with the related Loan Trustee of money or certain obligations of the United States or any agency or instrumentality thereof the payment of which is backed by the full faith and credit of the United States which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay when due (including as a consequence of redemption (in respect of which no premium is payable) in respect of which irrevocable notice is given on or prior to the date of such deposit) principal and interest with respect to all Equipment Notes issued thereunder in accordance with the terms of such Indenture. Such discharge may occur only if, among other things, there has been published by the Internal Revenue Service a ruling to the effect that holders of S-30 such Equipment Notes will not recognize income, gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount and in the same manner and at the same time as would have been the case if such deposit, defeasance and discharge had not occurred. (Indentures, Sections 10.01 and 10.02) Upon such a defeasance, or upon payment in full of the principal, interest and premium, if any, with respect to all Equipment Notes issued under such Indenture or deposit with the applicable Loan Trustee of money sufficient therefor no earlier than one year prior to the maturity or redemption thereof, the holders of such Equipment Notes will have no beneficial interest in or other rights with respect to the related Aircraft or other assets subject to the lien of the Indenture and such lien shall terminate. (Indentures, Sections 10.01 and 13.01) ASSUMPTION OF OBLIGATIONS BY UNITED Upon the voluntary termination of a Lease in connection with the exercise by United of any of its purchase options prior to the end of the term of such Lease, United may assume on a full recourse basis all of the obligations of the Owner Trustee (other than its obligations in its individual capacity) under the related Indenture, including the obligations to make payments with respect to the Equipment Notes. In such event, certain relevant provisions of the Lease, including (among others) provisions relating to maintenance, possession and use of the related Aircraft, liens, insurance and events of default will be incorporated into such Indenture, and the Equipment Notes issued under such Indenture will not be redeemed and will continue to be secured by such Aircraft. In addition, in certain circumstances United may pay in installments the portion of the purchase price for such Aircraft which is distributable to the Owner Participant and United's obligations to pay such installments may be secured by a lien on such Aircraft, which lien will be subject to the prior rights of the holders of the related Equipment Notes as provided in the Participation Agreement. It is a condition to such assumption that an opinion of counsel be delivered at the time of such assumption substantially to the effect that the Loan Trustee under such Indenture would, immediately following such assumption, be entitled to the benefits of section 1110 of the Bankruptcy Code with respect to such Aircraft (including the Engines related thereto), but such opinion need not be delivered with respect to an Aircraft to the extent that the benefits of such section 1110 are not available to the Loan Trustee with respect to such Aircraft or any Engine related thereto immediately prior to such assumption. (Leases, Section 19(b); Indentures, Section 7.03; Participation Agreements, Section 8(r) with respect to the 747 Aircraft and Section 8(l) with respect to the 777 Aircraft) FEDERAL INCOME TAX CONSEQUENCES Prospective investors should consult the section "Federal Income Tax Consequences" in the Prospectus for a discussion of the anticipated material federal income tax consequences of the purchase, ownership and disposition of Certificates. CERTAIN UTAH TAXES Ray, Quinney & Nebeker, counsel to the Trustee, has advised United that, in its opinion, under currently applicable law, assuming that the Trusts will not be taxable as corporations, but, rather, will be classified as grantor trusts under subpart E, Part I of Subchapter J of the Code, (i) the Trusts will not be subject to any tax (including, without limitation, net or gross income, tangible or intangible property, net worth, capital, franchise or doing business tax), fee or other governmental charge under the laws of the State of Utah or any political subdivision thereof and (ii) Certificate Owners that are not residents of or otherwise subject to tax in the State of Utah will not be subject to any tax (including, without limitation, net or gross income, tangible or intangible property, net worth, capital, franchise or doing business tax), fee or other governmental charge under the laws of the State of Utah or any political subdivision thereof as a result of purchasing, holding S-31 (including receiving payments with respect to) or selling a Certificate. Neither the Trusts nor the Certificate Owners will be indemnified for any state or local taxes imposed on them, and the imposition of any such taxes on a Trust could result in a reduction in the amounts available for distribution to the Certificate Owners of such Trust. In general, should a Certificate Owner or a Trust be subject to any state or local tax which would not be imposed if the Trustee were located in a different jurisdiction in the United States, the Trustee will resign and a new Trustee in such other jurisdiction will be appointed. ERISA CONSIDERATIONS Employee benefit plans subject to Title I of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), individual retirement accounts and employee benefit plans subject to Section 4975 of the Code (hereinafter referred to as "ERISA Plans" or "Plans"), may purchase Certificates issued by the Trusts, subject to certain legal restrictions. Under ERISA, any person who exercises any authority or control relating to management or disposition of the assets of an ERISA Plan is considered to be a fiduciary of such Plan. ERISA requires that fiduciaries of Plans cause the assets of such Plans to be invested prudently, for the exclusive benefit of participants and in a manner that does not result in a non-exempt "prohibited transaction" (as defined in ERISA or the Code). A fiduciary of a Plan contemplating the purchase of a Certificate should carefully consider how the purchase of a Certificate will relate to the Plan's investment portfolio and whether a prohibited transaction will result from such purchase. Governmental plans (as defined in Section 3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA) are not subject to the fiduciary responsibility and prohibited transaction provisions of ERISA and Section 4975 of the Code. However, such plans contemplating purchase of a Certificate should carefully consider how any state laws or other Code provisions may relate to such purchase. UNDERWRITING Subject to the terms and conditions of the Underwriting Agreement with United, the Underwriters named below have severally agreed to purchase from the Trustees the Certificates of each Trust in the aggregate principal amount set forth below opposite their respective names. The Underwriters are committed to purchase all of the Certificates if any are purchased.

All secondary trading in the Certificates will settle in immediately available funds. See "Description of the Certificates--Same-Day Settlement and Payment" in the Prospectus. S-32 United has agreed to indemnify the Underwriters against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended. United does not intend to apply for listing of the Certificates on a national securities exchange, but has been advised by the Underwriters that they presently intend to make a market in the Certificates, as permitted by applicable laws and regulations. No Underwriter is obligated, however, to make a market in the Certificates and any such market making may be discontinued at any time at the sole discretion of such Underwriter. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the Certificates. NatWest Capital Markets Limited ("NatWest"), a United Kingdom broker-dealer and a member of the Securities Futures Authority Limited, has agreed that, as part of the distribution of the Certificates offered hereby and subject to certain exceptions, it will not offer or sell any Certificates within the United States, its territories or possessions or to persons who are citizens thereof or residents therein. The underwriting agreement between United and the Underwriters does not limit the sale of the Certificates offered hereby outside of the United States. NatWest has also represented and agreed that (i) it has not offered or sold and will not offer or sell any Certificates to persons in the United Kingdom, except to persons whose ordinary activities involve acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995, (ii) it has complied with and will comply with all applicable provisions of the Financial Services Act 1986 with respect to anything done by it in relation to the Certificates in, from or otherwise involving the United Kingdom, and (iii) it has 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 Certificates to a person who is of a kind described in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemption) Order 1995 or is a person to whom such document may otherwise lawfully be issued or passed on. It is expected that delivery of the Certificates will be made against payment therefor on or about the date specified in the last paragraph of the cover page of this Prospectus Supplement, which will be the fifth business day following the date of pricing of the Certificates. Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Certificates on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the Certificates initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Certificates who wish to trade Certificates on the date of pricing or the next succeeding business day should consult their own advisor.
