DESCRIPTION OF UAL CAPITAL STOCK

         The following description of UAL's capital stock includes a summary of certain provisions of UAL's amended and restated certificate of incorporation and amended and restated bylaws. The following description of the terms of the Preferred Stock UAL may issue sets forth certain general terms and provisions of any series of Preferred Stock to which any prospectus supplement may relate. Particular terms of the Preferred Stock offered by any prospectus supplement and the extent, if any, to which these general terms and provisions shall apply to any series of Preferred Stock so offered will be described in the prospectus supplement relating to the applicable Preferred Stock. The applicable prospectus supplement may also state that any of the terms set forth in this description are inapplicable to such series of Preferred Stock. This description of UAL's capital stock does not purport to be complete and is subject to and qualified in its entirety by reference to applicable Delaware law and the provisions of UAL's amended and restated certificate of incorporation and any applicable certificates of designations, which have been or will be filed with the SEC.

General

        UAL is authorized to issue up to 1,000,000,000 shares of Common Stock, par value $0.01 per share ("UAL Common Stock"). UAL is also authorized to issue 250,000,000 shares of Preferred Stock, without par value ("Serial Preferred Stock"), one share of Class Pilot MEC Junior Preferred Stock, par value $0.01 per share, and one share of Class IAM Junior Preferred Stock, par value $0.01 per share.

Common Stock

Dividends

        The holders of UAL Common Stock will be entitled to receive dividends, if and when declared payable, from time to time by the UAL board of directors (the "Board").

Liquidation

        Upon any liquidation, dissolution or winding up of UAL, after all securities ranking prior to UAL Common Stock, including any shares of UAL's Serial Preferred Stock, Class Pilot MEC Junior Preferred Stock and Class IAM Junior Preferred Stock, have been paid in full that to which they are entitled, the holders of the then outstanding shares of UAL Common Stock will be entitled to receive, pro rata, the remaining assets of UAL available for distribution to its stockholders.

Voting Rights

        Each outstanding share of UAL Common Stock will entitle the holder thereof to one vote on each matter submitted to a vote at a meeting of stockholders. At meetings of stockholders, holders of UAL's Common Stock vote together as a single class with holders of UAL's Class Pilot MEC Junior Preferred Stock and Class IAM Junior Preferred Stock on all matters except the election of directors to the Board. Except as otherwise required by UAL's amended and restated certificate of incorporation, each director shall be elected by vote of a majority of the votes cast with respect to that director's election. However, if the number of director nominees exceeds the number of directors to be elected at any meeting of stockholders as of the date that is 10 days prior to the date UAL files its definitive proxy statement with the SEC, then each director shall be elected by a plurality of the votes cast and entitled to vote on the election of directors. The affirmative vote of holders of shares of UAL's capital stock representing a majority of the votes present in person or by proxy at the meeting and entitled to be cast on the matter will be required to approve any other matters.

        UAL Common Stock is not convertible into, or exchangeable for, any other class or series of capital stock. Holders of UAL Common Stock have no preemptive or other rights to subscribe for or purchase additional securities of UAL. UAL's amended and restated certificate of incorporation contains no sinking fund provisions or redemption provisions with respect to the UAL Common Stock. Shares of UAL Common Stock are not subject to calls or assessments. No personal liability will attach to holders under the laws of the State of Delaware (UAL's state of incorporation) or of the State of Illinois (the state in which UAL's principal place of business is located).

Such rights, preferences, powers and limitations as may be established could have the effect of discouraging an attempt to obtain control of UAL.

Ranking

        The Class IAM Junior Preferred Stock is deemed to rank on a parity with the Class Pilot MEC Junior Preferred Stock and senior to the UAL Common Stock as to amounts distributable upon liquidation, dissolution or winding up of UAL.

Foreign Ownership Limitation and Certain Anti-Takeover Provisions in UAL's Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws applicable to all UAL Capital Stock

Foreign Ownership Limitation

        UAL's amended and restated certificate of incorporation limits the total number of shares of equity securities held by all persons who fail to qualify as citizens of the United States to having no more than 24.9% of the voting power of all outstanding equity securities of UAL.

Undesignated Preferred Stock

        The ability to authorize undesignated Preferred Stock makes it possible for the Board to issue Preferred Stock with super voting, dividend or other special rights or preferences on a discriminatory basis that could impede the success of any attempt to acquire UAL. These and other provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of UAL.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

        UAL's amended and restated bylaws provide that special meetings of the stockholders may be called only (i) by both the Chief Executive Officer and the Chairman of the Board, (ii) by the Board or (iii) subject to certain requirements set forth in UAL's amended and restated bylaws, upon the written request of one or more stockholders of record of UAL that together have continuously held, for their own account or on behalf of others, beneficial ownership of at least a 25% aggregate "net long position" (as defined in UAL's amended and restated bylaws) of the outstanding UAL Common Stock for at least one year prior to the date such request is delivered to UAL.

        UAL's amended and restated bylaws establish advance notice procedures with respect to stockholder proposals for annual meetings and the nomination of candidates for election as directors to the Board, other than nominations by ALPA or the IAM or nominations made by or at the direction of the Board or a committee of the Board. In order for any matter to be "properly brought" before a meeting, a stockholder will have to comply with advance notice requirements and provide UAL with certain information. Additionally, vacancies and newly created directorships may be filled by a vote of a majority of the directors then in office, even though less than a quorum. UAL's amended and restated bylaws allow the Chief Executive Officer or Chairman, or his or her designee, to preside at a meeting to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquiror from conducting a solicitation of proxies to elect the acquiror's own slate of directors or otherwise attempting to obtain control of UAL.

Table of Contents

Proxy Access

        UAL's amended and restated bylaws contain a proxy access right provision to permit a stockholder or group of up to 20 stockholders satisfying specified eligibility requirements to include director nominees in UAL's proxy materials for annual meetings of stockholders. The maximum number of stockholder nominees permitted under these proxy access provisions is the greater of two or 20% of the Board elected by the holders of UAL Common Stock. To be eligible to use these proxy access provisions, such stockholder (or group) must, among other requirements:

•

have continuously owned 3% or more of the outstanding shares of UAL Common Stock throughout the three-year period preceding the date of the nomination notice, and continue to own at least 3% or more of the outstanding shares of UAL Common Stock through the date of the annual meeting;



•

represent that such stockholder (or group) did not acquire, and is not holding, such shares of UAL Common Stock for the purpose, or with the effect, of influencing or changing control of UAL; and



•

provide a written notice requesting the inclusion of director nominees in UAL's proxy materials and provide other required information to UAL not earlier than the close of business on the 150th day and not later than the close of business on the 120th day prior to the anniversary of the mailing date of UAL's proxy statement for the prior year's annual meeting of stockholders (with adjustments if the date for the upcoming annual meeting of stockholders is more than 30 days before or after the anniversary date of the prior year's annual meeting).

        The foregoing proxy access right is subject to additional eligibility, procedural and disclosure requirements set forth in UAL's amended and restated bylaws.

No Stockholder Action by Written Consent

        Pursuant to Section 228 of the Delaware General Corporation Law (the "DGCL"), any action required to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of stock entitled to vote thereon were present and voted, unless UAL's amended and restated certificate of incorporation provides otherwise. UAL's amended and restated certificate of incorporation provides that any action required or permitted to be taken by UAL stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by consent in writing by such stockholders.

        Unless otherwise provided in the applicable prospectus supplement, securities in registered form may be transferred or exchanged at the office of the trustee at which its corporate trust business is principally administered in the United States or at the office of the trustee or the trustee's agent in the Borough of Manhattan, the City and State of New York, at which its corporate agency business is conducted, subject to the limitations provided in the indenture, without the payment of any service charge, other than any tax or governmental charge payable in connection therewith. Securities in bearer form will be transferable only by delivery. Provisions with respect to the exchange of securities in bearer form will be described in the prospectus supplement relating to those securities in bearer form.

        Neither the issuer nor the registrar for the debt securities will be required (a) to issue, register the transfer of or exchange the debt securities of any series for the period beginning at the opening of business 15 days immediately preceding the mailing of a notice of redemption of the debt securities of that series selected for redemption and ending at the close of business on the day of such mailing or (b) to register the transfer of or exchange the debt securities of any series selected, called or being called for redemption as a whole or the portion being redeemed of any such debt securities selected, called or being called for redemption in part.

        All funds which the issuer pays to a paying agent or the trustee for the payment of principal of, premium, if any, or interest on any debt securities that remain unclaimed at the end of two years after such principal, premium, if any, or interest has become due and payable will be repaid to the issuer on its request, and the holders of such debt securities will thereafter look only to the issuer for payment thereof.

Global Securities

        The debt securities of a series may be issued in whole or in part in the form of one or more global securities. A global security is a debt security that represents, and is denominated in an amount equal to the aggregate principal amount of, all outstanding debt securities of a series, or any portion thereof, in either case having the same terms, including the same original issue date, date or dates on which principal and interest are due and interest rate or method of determining interest. A global security will bear the legend as prescribed in the indenture. A global security will be deposited with, or on behalf of, a depositary, which will be identified in the prospectus supplement relating to such debt securities. Global securities may be issued in either registered or bearer form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities represented thereby, a global security may not be transferred except as a whole by the depositary to a nominee of the depositary, by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any nominee of the depositary to a successor depositary or any nominee of such successor depositary.

        The specific terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to such debt securities. We anticipate that the following provisions will generally apply to depositary arrangements.

        Upon the issuance of a global security, the depositary for such global security will credit, on its book entry registration and transfer system, the respective principal amounts of the individual debt securities represented by such global security to the accounts of persons that have accounts with the depositary ("participants"). Such accounts shall be designated by the dealers or underwriters with respect to such debt securities or, if such debt securities are offered and sold directly by the issuer or

14

Table of Contents

through one or more agents, by the issuer or such agents. Ownership of beneficial interests in a global security will be limited to participants or persons that hold beneficial interests through participants. Ownership of beneficial interests in such global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary (with respect to interests of participants) or records maintained by participants (with respect to interests of persons other than participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limitations and laws may impair the ability to transfer beneficial interests in a global security.

        So long as the depositary for a global security, or its nominee, is the registered owner or holder of such global security, such depositary or nominee, as the case may be, will be considered the sole owner or holder of the individual debt securities represented by such global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have any of the individual debt securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of any of such debt securities in definitive form, and will not be considered the owners or holders thereof under the indenture.

        Subject to the restrictions applicable to securities in bearer form described in an applicable prospectus supplement (see "—Limitations on Issuance of Securities in Bearer Form" below), payments of principal, premium, and interest with respect to individual debt securities represented by a global security will be made to the depositary or its nominee, as the case may be, as the registered owner or holder of such global security. Neither the issuer, the trustee, any paying agent or registrar for such debt securities nor any agent of the issuer or the trustee will have any responsibility or liability for:

        (1)   any aspect of the records relating to or payments made by the depositary, its nominee or any participants on account of beneficial interests in a global security or for maintaining, supervising or reviewing any records relating to such beneficial interests;

        (2)   the payment to the owners of beneficial interests in the global security of amounts paid to the depositary or its nominee; or

        (3)   any other matter relating to the actions and practices of the depositary, its nominee or its participants.

        None of the issuer, the trustee, any paying agent or registrar for such debt securities or any agent of the issuer or the trustee will be liable for any delay by the depositary, its nominee or any of its participants in identifying the owners of beneficial interests in the global security, and the issuer and the trustee may conclusively rely on, and will be protected in relying on, instructions from the depositary or its nominee for all purposes.

        We expect that the depositary for a series of debt securities or its nominee, upon receipt of any payment of principal, premium or interest with respect to a definitive global security representing any of such debt securities, will immediately credit applicable participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security, as shown on the records of the depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers and registered in "street name." Such payments will be the responsibility of such participants. Receipt by owners of beneficial interests in a temporary global security of payments of principal, premium or interest with respect thereto will be subject to the restrictions described in an applicable prospectus supplement (see "—Limitation on Issuance of Securities in Bearer Form" below).

        If the depositary for a series of debt securities is at any time unwilling, unable or ineligible to continue as depositary, the issuer shall appoint a successor depositary. If a successor depositary is not appointed by the issuer within 90 days, the issuer will issue individual debt securities of such series in

exchange for the global security representing such series of debt securities. In addition, the issuer may at any time and in its sole discretion, subject to any limitations described in the prospectus supplement relating to such debt securities, determine to no longer have debt securities of a series represented by a global security and, in such event, will issue individual debt securities of such series in exchange for the global security representing such series of debt securities. Furthermore, if an event of default with respect to the debt securities of a series represented by a global security shall have happened and be continuing and owners of beneficial interests in such global security in an amount not less than a majority of the aggregate outstanding principal amount of such global security have delivered to the issuer and the trustee a notice indicating that the continuation of the book-entry system through such depositary is no longer in the best interests of the holders of the beneficial interests, such global security will be exchangeable for individual debt securities of such series.

Limitations on Issuance of Securities in Bearer Form

        The debt securities of a series may be issued as securities in registered form (which will be registered as to principal and interest in the register maintained by the registrar for such debt securities) or securities in bearer form (which will be transferable only by delivery). If such debt securities are issuable as securities in bearer form, the applicable prospectus supplement will describe certain special limitations and considerations that will apply to such debt securities.

Certain Covenants

        If debt securities are issued, the indenture, as supplemented for a particular series of debt securities, will contain certain covenants for the benefit of the holders of such series of debt securities, which will be applicable (unless waived or amended) so long as any of the debt securities of such series are outstanding, unless stated otherwise in the prospectus supplement. The specific terms of the covenants, and summaries thereof, will be set forth in the prospectus supplement relating to such series of debt securities.

Subordination

        Debt securities of a series, and any guarantees of such securities, may be subordinated, which we refer to as subordinated debt securities, to senior indebtedness (as defined in the applicable prospectus supplement) to the extent set forth in the prospectus supplement relating thereto. To the extent the issuer of any debt securities conducts operations through subsidiaries of such issuer, the holders of such debt securities (whether or not subordinated debt securities) will be structurally subordinated to the creditors of such subsidiaries except to the extent such subsidiary is a guarantor of such series of debt securities.

Events of Default

        Each of the following constitutes an event of default under the indenture with respect to any series of debt securities:

        (1)   default in any payment of the principal or premium, if any, on the debt securities of that series, when such amount becomes due and payable at maturity, upon acceleration, redemption or otherwise;

        (2)   failure to pay interest on any debt security of that series when such interest becomes due and payable, and such failure continues for a period of 30 days;

        (3)   failure to comply for 60 days after notice with any of the covenants or agreements applicable to the debt securities of that series (other than those referred to in (1) or (2) above) or the indenture or supplemental indenture related to that series of debt securities; or

        (4)   certain events of bankruptcy, insolvency or reorganization affecting the issuer.

16

Table of Contents

        A prospectus supplement may omit, modify or add to the foregoing events of default.

        A default under clause (3) above will not constitute an event of default with respect to any series of debt securities until the trustee notifies the issuer or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series notify the issuer and the trustee of the default and such issuer does not cure such default within the time specified in clause (3) above after receipt of such notice.

        If any event of default (other than an event of default relating to certain events of bankruptcy, insolvency or reorganization with respect to the issuer) occurs and is continuing with respect to a particular series of debt securities, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series by notice to the issuer (and to the trustee if such notice is given by the holders) may declare the principal amount of (or in the case of original issue discount debt securities, the portion thereby specified in the terms thereof) and accrued and unpaid interest on all the debt securities of that series to be immediately due and payable. In the case of certain events of bankruptcy, insolvency or reorganization with respect to the issuer, the principal amount of (or, in the case of original issue discount debt securities, the portion thereby specified in the terms thereof) and accrued interest on all the debt securities of that series shall automatically become and be immediately due and payable without any declaration or other act on the part of the trustee or any holders.

        The holders of a majority in aggregate principal amount of the debt securities of any series then outstanding may by notice to the trustee under the indenture waive any existing default or event of default and its consequences under the indenture with respect to such series of debt securities except (i) a default in the payment of the principal of (or, in the case of original issue discount debt securities of that series, the portion thereby specified in the terms thereof), premium, if any, and accrued and unpaid interest on the debt securities of such series, (ii) a default arising from the failure to redeem or purchase any debt security of that series when required pursuant to the terms of the indenture or (iii) a default in respect of a provision that cannot be amended under the indenture without the consent of each holder of the series affected.

        Subject to the provisions of the indenture relating to the duties of the trustee, in case an event of default shall occur and be continuing, the trustee is under no obligation to exercise any of its rights or powers under the indenture or debt securities at the request or direction of any of the holders of any series of debt securities, unless such holders have offered to the trustee indemnity or security satisfactory to it against any loss, liability or expense. Subject to such provisions for the indemnification of the trustee, the holders of at least a majority in aggregate principal amount of the outstanding debt securities of any series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series of debt securities. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture, that the trustee determines is unduly prejudicial to the rights of any other holder of such series of debt securities or that would subject the trustee to personal liability. Prior to taking any action under the indenture, the trustee is entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

        Except to enforce the right to receive payment of principal (or, in the case of original issue discount debt securities, the portion thereby specified in the terms thereof), premium, if any, and accrued and unpaid interest on the debt securities of any series when due, no holder of debt securities of that series has any right to pursue any remedy with respect to the indenture or debt securities unless:

•

such holder has previously given to the trustee written notice of a continuing event of default with respect to such series of debt securities;

17

Table of Contents

•

the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made a written request to the trustee to pursue such remedy;



•

such holder or holders have offered to the trustee security or indemnity satisfactory to the trustee against any loss, liability or expense;



•

the trustee has not complied with the request within 60 days after receipt of the request and the offer of security or indemnity; and



•

the holders of a majority in aggregate principal amount of the outstanding debt securities of that series do not give the trustee a direction inconsistent with the request during such 60-day period.

        However, such limitations do not apply to a suit instituted by a holder of a debt security of such series for the enforcement of payment of the principal (or, in the case of original issue discount debt securities, the portion thereby specified in the term thereof), premium, if any, or accrued and unpaid interest on such debt security on or after the applicable due date specified in such debt security.

        The indenture provides that if a default with respect to debt securities of any series occurs and is continuing and if it is actually known to a trust officer of the trustee, the trustee must mail to each holder of that series notice of the default within 90 days after it occurs. Except in the case of a default in the payment of principal of (or, in the case of original issue discount debt securities of that series, the portion thereby specified in the terms thereof), premium, if any, and accrued and unpaid interest on any debt security of that series when such amount becomes due and payable, the trustee may withhold notice if and so long as a committee of its trust officers in good faith determines that withholding notice is in the interests of the holders.

        The indenture requires the issuer with respect to an outstanding series of debt securities to furnish to the trustee, within 120 days after the end of each fiscal year, an officer's certificate as defined in the indenture, as to whether or not such officers know of any default with respect to such series of debt securities that occurred during such period and, if so, describing the default, its status and what action the issuer is taking or proposes to take with respect thereto.

        Street name and other indirect holders should consult their banks and brokers for information on their requirements for giving notice or taking other actions upon a default.

Modification and Waiver

        Modifications and amendments of the indenture as it applies to any series of debt securities or any of the other terms of such series may be made by the applicable issuer, any applicable guarantor and the trustee with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of such series.

        No such modification or amendment may, without the consent of each holder of an affected debt security:

•

make any change to the percentage of principal amount of the outstanding debt securities of the applicable series the holders of which must consent to an amendment;



•

reduce the principal amount of, premium, if any, or interest on, or extend the stated maturity or interest payment periods, of such debt security;



•

make such debt security payable in money or securities other than that stated in such debt security;



•

make any change that adversely affects such holder's right to require the applicable issuer to purchase such debt security in accordance with the terms thereof and under the indenture;

18

Table of Contents

•

impair the right of such holder to institute suit for the enforcement of any payment with respect to such debt securities;



•

in the case of any subordinated debt security or coupons appertaining thereto, make any change in the provisions of the indenture relating to subordination that adversely affects the rights of such holder under such provisions;



•

except as provided under "—Satisfaction and Discharge of the Indenture; Defeasance" below or in accordance with a guarantee, release any guarantor of such debt securities from any of its obligations under the guarantee or make any changes in the applicable guarantee that would adversely affect such holder; or



•

change the requirements relating to waiving a default in payment of principal of, premium, if any, or interest on the debt securities of a series, the right to bring suit to enforce such payments or the provisions relating to modifications or amendments described in this sentence.

        Without notice to or consent of any holder, the applicable issuer and guarantor with respect to a series of debt securities and the trustee may amend the indenture as it applies to such series or any of the other terms of such series for one or more of the following purposes:

•

to evidence the succession of another person to such issuer pursuant to the provisions of the indenture relating to consolidations, mergers and sales of assets and the assumption by such successor of such issuer's covenants, agreements and obligations in the indenture and with respect to the debt securities;



•

to surrender any right or power conferred upon such issuer, to add to the covenants such further covenants, restrictions, conditions or provisions for the protection of the holders of such series of debt securities, and to make the occurrence, or the occurrence and continuance, of a default in respect of any of such additional covenants, restrictions, conditions or provisions a default or an event of default under the indenture with respect to such series; provided, however, that with respect to any such additional covenant, restriction, condition or provision, such supplemental indenture may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other defaults, may provide for an immediate enforcement upon such default, may limit the remedies available to the trustee upon such default or may limit the right of holders of a majority in aggregate principal amount of any series of debt securities to waive such default;



•

to cure any ambiguity or correct or supplement any provision contained in the indenture, in any supplemental indenture, board resolution or officers' certificate or in any debt securities that may be defective or inconsistent with any other provision contained therein;



•

to convey, transfer, assign, mortgage or pledge any property to or with the trustee, or to make such other provisions in regard to matters or questions arising under the indenture as shall not adversely affect the interests of any holders of debt securities of such series;



•

to modify or amend the indenture in such a manner as to permit the qualification of the indenture or any supplemental indenture under the Trust Indenture Act as then in effect;



•

to add to or change any of the provisions of the indenture to provide that debt securities in bearer form may be registrable as to principal, to change or eliminate any restrictions on the payment of principal, premium or interest with respect to debt securities in bearer form, to permit securities in registered form to be exchanged for securities in bearer form or to permit or facilitate the issuance of debt securities of such series in uncertificated form, provided that any such action shall not adversely affect the interests of the holders of debt securities or any coupons of any series in any material respect;

Table of Contents

•

in the case of subordinated debt securities, to make any change in the provisions of the indenture or any supplemental indenture, board resolution or officers' certificate relating to subordination that would limit or terminate the benefits available to any holder of senior indebtedness under such provisions, subject to any consent required under the terms of such senior indebtedness;



•

to add guarantees with respect to the debt securities or to secure the debt securities;



•

to make any change that does not adversely affect the rights of any holder of debt securities of such series;



•

to evidence and provide for the acceptance of appointment by a successor or separate trustee with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the indenture by more than one trustee; or



•

to establish the form or terms of debt securities and coupons of any series, as described under "—General" above.

        UAL, United and the trustee may amend the indenture without notice to or consent of any holder to add to, change, or eliminate any of the provisions of the indenture, so long as any such addition, change or elimination not otherwise permitted under the indenture shall (a) neither apply to any debt security of any series outstanding at the time of the execution of such supplemental indenture and entitled to the benefit of such provision nor modify the rights of the holders of any such debt security with respect to such provision or (b) become effective only when there is no such debt security outstanding.

Mergers and Sales of Assets

        The indenture provides that the issuer with respect to any outstanding series of debt securities may not consolidate with or merge into any other person or convey, transfer or lease all or substantially all of its properties and assets to another person, unless among other items: (a) the resulting, surviving or transferee person is a corporation organized and existing under the laws of the United States, any state thereof or the District of Columbia and such person (if not such issuer) expressly assumes, by supplemental indenture, all obligations of such issuer under the applicable debt securities and the indenture; (b) no event of default with respect to any series of debt securities of such issuer issued under the indenture shall have occurred and be continuing; and (c) such issuer shall have provided the trustee with an officers' certificate and an opinion of counsel confirming compliance with the indenture with respect to such transaction. Upon the assumption of the issuer's obligations by such a person in such circumstances, subject to certain exceptions, such issuer shall be discharged from all obligations under the indenture.

Satisfaction and Discharge of the Indenture; Defeasance

        Unless otherwise provided for in the prospectus supplement, the indenture shall cease to be of any further effect with respect to any series of debt securities if (1) either (a) the issuer has delivered to the trustee for cancellation all debt securities of such series (with certain limited exceptions) or (b) all debt securities and coupons of such series not theretofore delivered to the trustee for cancellation shall have become due and payable, are by their terms to become due and payable at their stated maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice of redemption by the trustee in the name, and at the expense, of the issuer; and (2) the issuer shall have deposited with the trustee as trust funds an amount sufficient to pay and discharge the entire indebtedness on such debt securities not theretofore delivered to the trustee for cancellation, for principal (and premium, if any) and interest, if any, to the date of such

20

Table of Contents

deposit (in the case of debt securities which have become due and payable) or to the stated maturity or redemption date, as the case may be.

        In addition, the issuer shall have a "legal defeasance option" (pursuant to which the issuer may terminate, with respect to the debt securities of a particular series, all of its obligations under such debt securities and the indenture with respect to such debt securities) and a "covenant defeasance option" (pursuant to which the issuer may terminate, with respect to the debt securities of a particular series, its obligations with respect to such debt securities under certain specified covenants with respect to such debt securities). If the legal defeasance option is exercised with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default. If the covenant defeasance option is exercised with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default related to the specified covenants.

        The applicable prospectus supplement will describe the procedures the issuer must follow in order to exercise its defeasance options.

Regarding the Trustee

        The indenture provides that, except during the continuance of an event of default, the trustee will perform only such duties as are specifically set forth in the indenture. During the existence of an event of default, the trustee will exercise such rights and powers vested in it under the indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

        The indenture and provisions of the Trust Indenture Act that are incorporated by reference therein contain limitations on the rights of the trustee, should it become one of an issuer's creditors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claim as security or otherwise. The trustee is permitted to engage in other transactions with any issuer or any of its affiliates; provided, however, that if it acquires any conflicting interest (as defined in the indenture or in the Trust Indenture Act), it must eliminate such conflict or resign.

Governing Law

        The indenture is, and the debt securities will be, governed by the laws of the State of New York.

DESCRIPTION OF DEPOSITARY SHARES

         The following summary of certain provisions of the depositary shares does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the deposit agreement that will be filed with the SEC in connection with the offering of such depositary shares.

        UAL may offer fractional shares of Preferred Stock, rather than full shares of Preferred Stock. If UAL decides to offer fractional shares of Preferred Stock, it will issue receipts for depositary shares. Each depositary share will represent a fraction of a share of a particular series of Preferred Stock, and the prospectus supplement will indicate that fraction. The shares of Preferred Stock represented by depositary shares will be deposited under a deposit agreement between UAL and a depositary that is a bank or trust company that meets certain requirements and is selected by UAL. The depositary will be specified in the applicable prospectus supplement. Each owner of a depositary share will be entitled to all of the rights and preferences of the Preferred Stock represented by the depositary share. The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of Preferred Stock in accordance with the terms of the offering.

        We have summarized selected provisions of the deposit agreement and the depositary receipts, but the summary is qualified by reference to the provisions of the deposit agreement and the depositary receipts. The particular terms of any series of depositary shares will be described in the applicable prospectus supplement. If so indicated in the prospectus supplement, the terms of any such series may differ from the terms set forth below.

Dividends

        The depositary will distribute all cash dividends or other cash distributions received by it in respect of the Preferred Stock to the record holders of depositary shares relating to such preferred shares in proportion to the numbers of depositary shares held on the relevant record date. The amount made available for distribution will be reduced by any amounts withheld by the depositary or UAL on account of taxes.

        In the event of a distribution other than in cash, the depositary will distribute securities or property received by it to the record holders of depositary shares in proportion to the numbers of depositary shares held on the relevant record date, unless the depositary determines that it is not feasible to make such distribution. In that case, the depositary may make the distribution by such method as it deems equitable and practicable. One such possible method is for the depositary to sell the securities or property and then distribute the net proceeds from the sale as provided in the case of a cash distribution.

Withdrawal of Shares

        Upon surrender of depositary receipts representing any number of whole shares at the depositary's office, unless the related depositary shares previously have been called for redemption, the holder of the depositary shares evidenced by the depositary receipts will be entitled to delivery of the number of whole shares of the related series of Preferred Stock and all money and other property, if any, underlying such depositary shares. However, once such an exchange is made, the Preferred Stock cannot thereafter be redeposited in exchange for depositary shares. Holders of depositary shares will be entitled to receive whole shares of the related series of Preferred Stock on the basis set forth in the applicable prospectus supplement. If the depositary receipts delivered by the holder evidence a number of depositary shares representing more than the number of whole shares of Preferred Stock of the related series to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares, provided that the depositary will not issue any receipt evidencing a fractional depositary share.

22

Table of Contents

Redemption of Depositary Shares

        Whenever UAL redeems the Preferred Stock, the depositary will redeem a number of depositary shares representing the same number of shares of Preferred Stock so redeemed. If fewer than all of the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot, pro rata or by any other equitable method as the depositary may determine.

Voting of Underlying Shares

        Upon receipt of notice of any meeting at which the holders of the Preferred Stock of any series are entitled to vote, the depositary will mail the information contained in the notice of the meeting to the record holders of the depositary shares relating to that series of preferred shares. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights represented by the number of shares of Preferred Stock underlying the holder's depositary shares. The depositary will endeavor, to the extent it is practical to do so, to vote the number of whole shares of Preferred Stock underlying such depositary shares in accordance with such instructions. UAL will agree to take all reasonable actions that the depositary may deem necessary in order to enable the depositary to do so. To the extent the depositary does not receive specific instructions from the holders of depositary shares relating to such preferred shares, it will abstain from voting such shares of Preferred Stock.

Amendment and Termination of Deposit Agreement

        The form of depositary receipt evidencing the depositary shares and any provision of the applicable deposit agreement may at any time be amended by agreement between UAL and the depositary. With the consent of the depositary, UAL may amend the deposit agreement from time to time in any manner that it desires. However, if the amendment would materially and adversely alter the rights of the existing holders of depositary shares, the amendment would need to be approved by the holders of at least a majority of the depositary shares then outstanding.

        The deposit agreement may be terminated by UAL or the depositary if:

•

all outstanding depositary shares have been redeemed; or



•

there has been a final distribution in respect of the shares of Preferred Stock of the applicable series in connection with our liquidation, dissolution or winding up and such distribution has been made to the holders of depositary receipts.

Resignation and Removal of Depositary

        The depositary may resign at any time by delivering to UAL notice of its election to do so. UAL may remove a depositary at any time. Any resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment.

Charges of Depositary

        UAL will pay all transfer and other taxes and governmental charges arising solely from the existence of any depositary arrangements. UAL will pay all charges of each depositary in connection with the initial deposit of the preferred shares of any series, the initial issuance of the depositary shares, any redemption or exchange of such preferred shares and any withdrawals of such preferred shares by holders of depositary shares. Holders of depositary shares will be required to pay any other transfer taxes and governmental charges.

23

Table of Contents

Notices

        Each depositary will forward to the holders of the applicable depositary shares all notices, reports and communications from UAL which are delivered to such depositary and which UAL is required to furnish the holders of the preferred shares.

Limitation of Liability

        The deposit agreement contains provisions that limit UAL's liability and the liability of the depositary to the holders of depositary shares. Both the depositary and UAL are also entitled to an indemnity from the holders of the depositary shares prior to bringing, or defending against, any legal proceeding pertaining to the rights of the holders of the depositary shares. UAL or any depositary may rely upon written advice of counsel or accountants, or information provided by persons presenting preferred shares for deposit, holders of depositary shares or other persons believed by UAL or it to be competent and on documents believed by UAL or them to be genuine.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

         The following summary of certain provisions of the stock purchase contracts and stock purchase units does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the stock purchase contract or stock purchase unit, as applicable, that will be filed with the SEC in connection with the offering of such securities.

        UAL may issue stock purchase contracts, including contracts obligating holders to purchase from it, and obligating UAL to sell to the holders, a specified number of shares of UAL Common Stock or Preferred Stock at a future date or dates, which we refer to in this prospectus as "stock purchase contracts." The price per share of the UAL Common Stock or Preferred Stock and the number of shares of UAL Common Stock or Preferred Stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and our debt securities, Preferred Stock or warrants or debt obligations of third parties, including U.S. treasury securities, securing the holders' obligations to purchase shares of UAL Common Stock or Preferred Stock under the stock purchase contracts, which we refer to herein as "stock purchase units." The stock purchase contracts may require holders to secure their obligations under the stock purchase contracts in a specified manner and, in certain circumstances, we may deliver newly issued prepaid stock purchase contracts upon release to a holder of any collateral securing such holder's obligations under the original stock purchase contract. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase units or vice versa, and those payments may be unsecured or refunded on some basis.

        The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units and, if applicable, prepaid stock purchase contracts. The description in the prospectus supplement will not necessarily be complete, and reference will be made to the stock purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the stock purchase contracts or stock purchase units, which will be filed with the SEC each time UAL issues stock purchase contracts or stock purchase units. Material United States federal income tax considerations applicable to the stock purchase units and the stock purchase contracts will also be discussed in the applicable prospectus supplement.

DESCRIPTION OF SUBSCRIPTION RIGHTS

         The following summary of certain provisions of the subscription rights does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the certificate evidencing the subscription rights that will be filed with the SEC in connection with the offering of such subscription rights.

General

        UAL may issue subscription rights to purchase shares of UAL Common Stock, Preferred Stock, depositary shares or warrants to purchase shares of UAL Common Stock, Preferred Stock or depositary shares. Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any subscription rights offering to UAL's stockholders, UAL may enter into a standby underwriting arrangement with one or more underwriters pursuant to which such underwriters will purchase any offered securities remaining unsubscribed for after such subscription rights offering. In connection with a subscription rights offering to UAL's stockholders, UAL will distribute certificates evidencing the subscription rights and a prospectus supplement to its stockholders on the record date that UAL sets for receiving subscription rights in such subscription rights offering.

        The applicable prospectus supplement will describe the following terms of subscription rights in respect of which this prospectus is being delivered:

•

the title of such subscription rights;



•

the securities for which such subscription rights are exercisable;



•

the exercise price for such subscription rights;



•

the number of such subscription rights issued to each stockholder;



•

the extent to which such subscription rights are transferable;



•

the date on which the right to exercise such subscription rights shall commence, and the date on which such rights shall expire (subject to any extension);



•

the extent to which such subscription rights include an over-subscription privilege with respect to unsubscribed securities;



•

if applicable, the material terms of any standby underwriting or other purchase arrangement that we may enter into in connection with the subscription rights offering; and



•

any other terms of such subscription rights, including terms, procedures and limitations relating to the exchange and exercise of such subscription rights.

Exercise of Subscription Rights

        Each subscription right will entitle the holder of the subscription right to purchase for cash such amount of shares of UAL Common Stock, Preferred Stock, depositary shares, warrants or any combination thereof, at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the subscription rights offered thereby. Subscription rights may be exercised at any time up to the close of business on the expiration date for such subscription rights set forth in the prospectus supplement. After the close of business on the expiration date, all unexercised subscription rights will become void.

        Subscription rights may be exercised as set forth in the prospectus supplement relating to the subscription rights offered thereby. Upon receipt of payment and the subscription rights certificate properly completed and duly executed at the corporate trust office of the subscription rights agent or any other office indicated in the prospectus supplement, UAL will forward, as soon as practicable, the shares of UAL Common Stock, Preferred Stock, depositary shares or warrants purchasable upon such exercise. UAL may determine to offer any unsubscribed offered securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as set forth in the applicable prospectus supplement.

DESCRIPTION OF WARRANTS

         The following summary of certain provisions of the warrants does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the warrant agreement that will be filed with the SEC in connection with the offering of such warrants.

General

        UAL may issue warrants for the purchase of debt securities, UAL Common Stock or Preferred Stock. Warrants may be issued independently or together with debt securities, UAL Common Stock or Preferred Stock offered by any prospectus supplement and may be attached to or separate from any such offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between UAL and a bank or trust company, as warrant agent.
