SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference contain various “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Exchange Act which represent our expectations or beliefs concerning future events. When used in this prospectus and in documents incorporated herein by reference, the words “believes”, “expects”, “plans”, “anticipates”, and similar expressions are intended to identify forward-looking statements.

     Forward-looking statements include, without limitation, our expectations concerning operations and financial conditions, including changes in capacity, revenues, and costs, expectations as to future financing needs, overall economic conditions and plans and objectives for future operations, the impact on us of the events of September 11, 2001 and of our results of operations for the past two years and the sufficiency of our financial resources to absorb that impact. Other forward-looking statements include statements which do not relate solely to historical facts, such as, without limitation, statements which discuss the possible future effects of current known trends or uncertainties, or which indicate that the future effects of known trends or uncertainties cannot be predicted, guaranteed, or assured.

     All forward-looking statements in this prospectus and the documents incorporated by reference are based upon information available to us on the date of this prospectus or such document. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, or otherwise. Forward-looking statements are subject to a number of factors that could cause actual results to differ materially from our expectations.

     The following factors, in addition to those discussed under the caption “Risk Factors” in each prospectus supplement and other possible factors not listed, could cause our actual results to differ materially from those expressed in forward-looking statements: the uncertain financial and business environment we face, the struggling economy, high fuel prices and the availability of fuel, the residual effects of the war in Iraq, conflicts in the Middle East, historically low fare levels and the general competitive environment, our ability to implement our restructuring program and the effect of the program on our operational performance and service levels, uncertainties with respect to our international operations, changes in our business strategy, actions by U.S. or foreign government agencies, the possible occurrence of additional terrorist attacks, another outbreak of SARS, our or American Airlines, Inc.’s inability to satisfy existing liquidity requirements or other covenants in certain of our or American Airlines, Inc.’s credit agreements and the availability of future financing.

     Additional information concerning these and other factors is contained in our and American Airlines, Inc.’s SEC filings, including but not limited to our and American Airlines, Inc.’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2003, June 30, 2003 and September 30, 2003 and our and American Airlines, Inc.’s Annual Reports on Form 10-K for the year ended December 31, 2002.

THE COMPANY

     AMR Corporation was incorporated in October 1982. AMR’s operations fall almost entirely in the airline industry. AMR’s principal subsidiary, American Airlines, Inc., was founded in 1934. On April 9, 2001, American Airlines, Inc. (through a wholly owned subsidiary, TWA Airlines LLC (“TWA LLC”)) purchased substantially all of the assets and assumed certain liabilities of Trans World Airlines, Inc. (“TWA”), the eighth largest U.S. carrier. American Airlines, Inc., including TWA LLC (collectively, “American”), is the largest scheduled passenger airline in the world. At the end of 2002, American provided scheduled jet service to more than 152 destinations throughout North America, the Caribbean, Latin America, Europe and the Pacific. American is also one of the largest

3

scheduled air freight carriers in the world, providing a wide range of freight and mail services to shippers throughout its system.

     In addition, AMR Eagle Holding Corporation, a wholly-owned subsidiary of AMR, owns two regional airlines which do business as “American Eagle” — American Eagle Airlines, Inc. and Executive Airlines, Inc. (collectively the "American Eagle Carriers”). In addition, American contracts with two independently owned regional airlines which do business as the “AmericanConnection” (the “AmericanConnection Carriers”). The American Eagle Carriers and the AmericanConnection Carriers provide connecting service from eight of American’s high-traffic cities to smaller markets throughout the United States, Canada, the Bahamas and the Caribbean.

     AMR Investment Services, Inc., a wholly-owned subsidiary of AMR (“AMR Investment”), is responsible for the investment and oversight of the assets of AMR’s defined benefit and defined contribution plans, as well as its short-term investments.

     The postal address for AMR’s and American’s principal executive offices is P.O. Box 619616, Dallas/Fort Worth Airport, Texas 75261-9616 (Telephone: 817-963-1234). AMR’s Internet address is http://www.amrcorp.com. Information on AMR’s website is not incorporated into this prospectus and is not a part of this prospectus.

     AMR conducts all of its business through its wholly owned operating subsidiaries, including American Airlines, Inc. AMR does not maintain a borrowing facility and is dependent on the cash flow generated by the operations of its subsidiaries and on dividends and other payments to it from its subsidiaries to meet its liquidity needs and obligations, including obligations with respect to debt securities, dividends on capital stock and other obligations on the securities described in this prospectus. American Airlines, Inc. is a separate and distinct legal entity and although it may unconditionally guarantee AMR’s obligations with respect to one or more of securities described in this prospectus, due to limitations and restrictions in its debt instruments, it may be unable to pay any amounts due on such guarantee or to provide AMR with funds for AMR’s payment obligations on such securities, by dividend, distribution, loan or other payment. Future borrowings by AMR, American Airlines, Inc. and AMR’s other subsidiaries may include additional restrictions. In addition, under applicable state law, American Airlines, Inc. and AMR’s other subsidiaries may be limited in the amounts they are permitted to pay as dividends on their capital stock.

     The securities described in this prospectus and any guarantee by American Airlines, Inc. with respect to any such securities will represent unsecured senior obligations and rank equal in right of payment with all the existing and future unsecured and unsubordinated indebtedness of AMR and American Airlines, Inc., respectively. In the event of any distribution or payment of assets in any foreclosure, dissolution, winding-up, liquidation, reorganization or other bankruptcy proceeding involving AMR or American Airlines, Inc., holders of secured indebtedness will have a prior claim to those assets that constitute their collateral. In addition, the securities described in this prospectus and any guarantee by American Airlines, Inc. with respect to any such securities will be “structurally subordinated” to all existing and future liabilities (including debt and trade payables) of the existing and future subsidiaries of AMR (other than American Airlines, Inc. to the extent of such guarantee) and American Airlines, Inc., respectively. Such subordination occurs because, as a general matter, claims of creditors of a subsidiary which is not a guarantor of parent company debt, including trade creditors, will have priority with respect to the assets and earnings of the subsidiary over the claims of creditors of its parent company.

RATIOS OF EARNINGS TO FIXED CHARGES

     The following table sets forth the ratios of earnings to fixed charges of AMR and of American for the periods indicated:

4

     ⁽¹⁾ For the year ended December 31, 2001, AMR earnings were not sufficient to cover fixed charges. We needed additional earnings of $2,900 million to achieve a ratio of earnings to fixed charges of 1.0.

     ⁽²⁾ In April 2001, the board of directors of American approved the unconditional guarantee by American (the “American Guarantee”) of the existing debt obligations of AMR. As such, as of December 31, 2001, American unconditionally guaranteed through the life of the related obligations approximately $676 million of unsecured debt and approximately $573 million of secured debt. The impact of these unconditional guarantees is not included in the above computation. For the year ended December 31, 2001, earnings were not sufficient to cover fixed charges. American needed additional earnings of $2,584 million to achieve a ratio of earnings to fixed charges of 1.0.

     ⁽³⁾ For the year ended December 31, 2002, AMR earnings were not sufficient to cover fixed charges. We needed additional earnings of $3,946 million to achieve a ratio of earnings to fixed charges of 1.0.

     ⁽⁴⁾ At December 31, 2002, American’s exposure under the American Guarantee was approximately $636 million with respect to unsecured debt and approximately $538 million with respect to secured debt. For the year ended December 31, 2002, earnings were not sufficient to cover fixed charges. American needed additional earnings of $3,749 million to achieve a ratio of earnings to fixed charges of 1.0.

     ⁽⁵⁾ For the nine months ended September 30, 2003, AMR earnings were not sufficient to cover fixed charges. We needed additional earnings of $1,171 million to achieve a ratio of earnings to fixed charges of 1.0.

     ⁽⁶⁾ At September 30, 2003, American’s exposure under the American Guarantee was approximately $936 million with respect to unsecured debt and approximately $503 million with respect to secured debt. For the nine months ended September 30, 2003, earnings were not sufficient to cover fixed charges. American needed additional earnings of $1,239 million to achieve a ratio of earnings to fixed charges of 1.0.

     For purposes of the table, “earnings” represents consolidated income from continuing operations before income taxes, extraordinary items, cumulative effect of accounting change and fixed charges (excluding interest capitalized). “Fixed charges” consists of interest expense (including interest capitalized), amortization of debt expense and the portion of rental expense we deem representative of the interest factor.

     Our ratio of earnings to combined fixed charges and preferred stock dividends has been the same as the ratio of earnings to fixed charges for each of the above periods because we have not had any shares of preferred stock outstanding during the last five years and have, therefore, not paid any dividends on preferred stock.

USE OF PROCEEDS

     Except as we may describe otherwise in a prospectus supplement, the net proceeds from the sale of the securities will be available for general corporate purposes, including, among other possible uses, the repayment of short-term or long-term debt or lease obligations, the acquisition of aircraft by American Airlines, Inc. or our other subsidiaries and other capital expenditures. We may also use the proceeds for temporary investments until we need them for general corporate purposes.

DIVIDEND POLICY

     We have paid no cash dividends on our common stock and have no current intention of doing so. Any future determination to pay cash dividends will be at the discretion of our board of directors, subject to applicable limitations under Delaware law, and will be dependent upon our results of operations, financial condition, contractual restrictions and other factors deemed relevant by our board of directors.

DESCRIPTION OF DEBT SECURITIES

Introduction

     We may elect to offer unsecured debt securities. We will issue the debt securities in one or more series under an indenture, which we refer to as the “indenture”, to be entered into between us and Wilmington Trust Company, as trustee. The debt securities will rank equal in right of payment with all of our other unsecured, unsubordinated indebtedness. The debt securities may include debentures, notes or other kinds of unsecured debt obligations. The amount of debt securities that we can issue under the indenture is unlimited.

     The description of the terms of the debt securities and indenture in this prospectus is a summary. When we offer to sell a series of debt securities, we will summarize in a prospectus supplement the particular terms of such series of debt securities that we believe will be the most important to your decision to invest in such series of debt securities. As the terms of such series of debt securities may differ from the summary in this prospectus, the summary in this prospectus is subject to and qualified by reference to the summary in such prospectus supplement, and you should rely on the summary in such prospectus supplement instead of the summary in this prospectus if the summary in such prospectus supplement is different from the summary in this prospectus. You should keep in mind, however, that it is the debt securities, and the indenture, and not the summaries in this prospectus or such prospectus supplement, which define your rights as a holder of debt securities of such series. There may be other provisions in such debt securities and the indenture that are also important to you. You should carefully read these documents for a full description of the terms of such debt securities. The indenture is filed as an exhibit to the registration statement that includes this prospectus. See “Where You Can Find More Information” for information on how to obtain a copy of the indenture.

     In this description, we include references in parentheses to certain sections of the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in any prospectus supplement, such sections or defined terms are incorporated by reference here or in the prospectus supplement.

     The debt securities will not be secured by any of our property or assets. Accordingly, your ownership of debt securities will mean that you will be one of AMR’s unsecured creditors. See “The Company”. Unless we tell you otherwise in an applicable prospectus supplement, the indenture does not limit the amount of other indebtedness or securities that may be issued by us or any of our subsidiaries. In addition, unless we tell you otherwise in an applicable prospectus supplement, the indenture does not contain any financial covenants or restrictions on the payment of dividends, the incurrence of debt, securing our debt or the issuance or repurchase of our debt securities, or any covenants or other provisions to afford protection to holders of debt securities in the event of a highly leveraged transaction or a change in control.

Specific Terms of Debt Securities

     We may issue the debt securities in one or more series through an indenture that supplements the indenture or through a resolution of our board of directors or an authorized committee of our board of directors.

     A prospectus supplement will describe specific terms relating to the series of debt securities then being offered. These terms may include some or all of the following:

6

7

(Section 3.1 of the indenture)

     Debt securities may also be issued under the indenture upon the exercise of warrants or delivery upon settlement of stock purchase contracts. See “Description of Warrants” and “Description of Stock Purchase Contracts and Stock Purchase Units”.

     Unless we tell you otherwise in the applicable prospectus supplement, debt securities will not be listed on any securities exchange.

     Unless we tell you otherwise in the applicable prospectus supplement, debt securities will be issued in fully registered form without coupons. If debt securities of any series are issued in bearer form, the applicable prospectus supplement will describe special restrictions and considerations, including special offering restrictions and special federal income tax considerations, applicable to such debt securities and to payments on and transfer and exchange of such debt securities. Bearer debt securities generally will be transferable by delivery. (Section 3.5 of the indenture) The indenture refers to the bearer of a bearer debt security as the “holder” of that debt security. (Section 1.1 of the indenture)

     One or more series of debt securities may be sold at a substantial discount below their stated principal amount. Such a series of debt securities is issued at an “original issue discount”. Typically, a debt security that is issued at an “original issue discount” will not bear interest or will bear interest at an interest rate that is below the market interest rate at the time of issuance. If we issue debt securities at an “original issue discount”, the applicable prospectus supplement will describe certain special federal income tax and other considerations applicable to such debt securities.

     If the purchase price of any debt securities is payable in foreign currencies, composite currencies or currency units, if any debt securities are denominated in foreign currencies, composite currencies or currency units, or if any debt securities are payable in foreign currencies, composite currencies or currency units, the applicable prospectus supplement will describe the special restrictions, elections and other specific terms and federal income tax considerations and certain other important information, with respect to such debt securities and such foreign currencies, composite currencies or currency units.

     The principal, premium, interest or other payments on debt securities may be determined by reference to an index, formula or other method. Such an index, formula or other method may be based, without limitation, on the price of one or more commodities, derivatives or securities; a commodities, derivatives, securities exchange or other index; a foreign currency or currencies or one or more composite currencies or currency units; or any other variable or variables or any relationship between any variables or combination of variables. Holders of such debt securities may receive a principal payment or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable index, formula or other factor or changes in any applicable variable or variables. If we issue debt securities the payments on which are based on such an index, formula or other method, the applicable prospectus supplement will describe that index, formula or other method and other specific terms and certain special federal income tax and other considerations applicable to such debt securities.

     One or more series of debt securities may be variable rate debt securities that may be exchangeable for fixed rate debt securities, or fixed rate debt securities exchangeable for variable rate debt securities. The applicable prospectus supplement will describe specific terms, federal income tax considerations and certain other important information.

8

     We may issue debt securities of a particular series at different times. In addition, we may issue debt securities within a series with terms different from the terms of other debt securities of that series.

     Subject to applicable law, we or any of our affiliates may at any time purchase or repurchase debt securities of any series in any manner and at any price. Debt securities of any series purchased by us or any of our affiliates may be held or surrendered by the purchaser of the debt securities for cancellation.

Registered Securities

     As noted above, unless we tell you in a prospectus supplement that the specific debt securities described in that prospectus supplement are bearer debt securities, the debt securities will be “registered securities”. We and the trustee may treat the person in whose name a registered debt security is registered under any indenture as the owner of that debt security for all purposes, including for the purpose of receiving payments on that debt security. (Section 3.8 of the indenture) The indenture refers to each person in whose name a registered debt security is registered as the “holder” of that debt security. (Section 1.1 of the indenture)

     Except as described below under “Global Debt Securities” or in the applicable prospectus supplement, a holder can exchange or transfer debt securities in registered form at the office of the trustee. Initially, the trustee will act as our agent for registering such debt securities in the names of holders and transferring such debt securities. We may appoint another entity at any time to perform this role or we may perform it ourselves. The entity performing the role of maintaining the list of registered holders and performing transfers is called the “registrar”. (Sections 3.5 and 9.2 of the indenture)

     Unless we tell you otherwise in the applicable prospectus supplement, a holder seeking to transfer or exchange a registered debt security will not be required to pay a service charge to us, the registrar or the trustee, but such holder may be required to pay any tax or other governmental charge associated with the transfer or exchange. (Section 3.5 of the indenture)

     If you are not the holder of any debt securities in registered form, your rights relating to those debt securities will be governed in part by applicable laws and by the account rules and policies of the broker, bank or financial intermediary through which you invest in such debt securities and any other financial intermediary that holds interests directly or indirectly in such debt securities (including any depositary referred to below under “Global Debt Securities”). None of AMR, American Airlines, Inc. or the trustee has any responsibility for the account rules, policies, actions or records of any broker, bank or other financial intermediary through which you hold (directly or indirectly) your beneficial interest in a debt security in registered form.

     If you are not the holder of any debt securities in registered form, you should consult the broker, bank or other financial intermediary through which you invest in such debt securities for information on your rights in respect of such debt securities. In particular, you should ask how you will receive payments, and whether you will be able to provide instructions as to how such broker, bank or other financial intermediary should exercise the rights of a “holder” under the indenture.

Global Debt Securities

     We may specify in the applicable prospectus supplement that the debt securities of a series will be issued in the form of fully registered global securities (“registered global securities”). Registered global securities will be registered in the name of a financial institution we select. This financial institution, which will be the sole direct holder of the registered global securities, is called the “depositary”. We will identify any depositary in the applicable prospectus supplement. Any person wishing to own a debt security represented by a registered global security must do so indirectly by virtue of an account with a broker, bank or other financial intermediary that in turn has an account with the depositary, or with another financial intermediary that itself has an account with the depositary. The debt securities represented by the registered global securities may not be transferred to the name of any other holder unless the special circumstances described below occur.

     Special Investor Considerations for Registered Global Securities. Our obligations with respect to registered global securities, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to persons who are registered holders of those debt securities. For example, once a payment on a registered global security is made to the depositary, as sole holder of that registered global security, neither we nor the trustee

9

has any further responsibility for that payment even if it is not passed along to the correct owners of the beneficial interests in that registered global security.

     As long as the debt securities are represented by registered global securities:

     You should consult the broker, bank or other financial intermediary through which you invest in debt securities represented by registered global securities for information on your rights in respect of such debt securities. In particular, you should ask how you will receive payments and whether you will be able to provide instructions as to how the depositary should exercise the rights of a “holder” under the indenture.

     Special Situations When a Registered Global Security Will Be Terminated. In the special situations described in the next paragraph, a registered global security will terminate and interests in it will be exchanged for physical certificates representing debt securities. After that exchange, we believe that you likely will be able to choose whether to hold debt securities directly in your own name or indirectly through an account at a bank or broker or other financial intermediary. However, when a registered global security terminates, the depositary (and not AMR, American Airlines, Inc. or the trustee) will be responsible for determining the names of the institutions that will be the initial direct holders of the debt securities. You must consult your own bank or broker or other financial intermediary at such time to find out how to have your interests in debt securities transferred to your own name, if you wish to become a direct holder.

     The special situations for termination of a registered global security are:

(Section 3.5 of the indenture) In addition, a prospectus supplement may list situations for terminating a registered global security that would apply only to the particular series of debt securities covered by that prospectus supplement.

10

     Bearer Global Securities. The debt securities of a series may also be issued wholly or partially in the form of one or more bearer global securities (“bearer global securities”) that will be deposited with a depositary, or with a nominee for such depositary, identified in the applicable prospectus supplement. Any such bearer global securities may be issued in temporary or permanent form. (Sections 3.4 and 3.5 of the indenture) The applicable prospectus supplement will describe the specific terms and procedures, including the depositary arrangement, with respect to any portion of a series of debt securities to be represented by bearer global securities.

Payments

     Unless we tell you otherwise in the applicable prospectus supplement, we will generally deposit interest, principal and any other money due on the debt securities, in the designated currency, with the trustee, and the trustee will act as our agent for making payments on the debt securities. We may change this appointment to another entity or perform this role ourselves. The entity performing the role of making payments is called the “paying agent”. We may, at our option, make any interest payments on debt securities in registered form by having the trustee mail checks or make wire transfers to the registered holders listed in the registrar’s records. (Sections 3.7(a) and 9.2 of the indenture) If you are not the holder of any debt securities in registered form, you must make your own arrangements with the bank, broker or other financial intermediary through which you invest in such debt securities to receive payments.

     Unless we tell you otherwise in the applicable prospectus supplement, interest, if any, will be payable to each holder listed in the registrar’s records at the close of business on a particular day in advance of each due date for interest, even if such holder no longer owns the debt security on the interest due date. That particular day is called the “record date” and will be stated in the prospectus supplement. (Section 3.7(a) of the indenture) Persons buying and selling debt securities between a record date and an interest payment date must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the registered holder on the record date.

     Unless we tell you otherwise in the applicable prospectus supplement, interest payable on any debt security in registered form that is not punctually paid or duly provided for on any interest payment date will cease to be payable to the holder in whose name such debt security is registered on the relevant record date. Such defaulted interest will instead be payable to the person in whose name such debt security is registered on the special record date or other specified date determined in accordance with the indenture. (Section 3.7(b) of the indenture)

     We will make payments on debt securities in bearer form in the currency and in the manner designated in the applicable prospectus supplement, subject to any relevant laws and regulations, at such paying agencies outside the United States as we may appoint from time to time. The paying agents outside the United States initially appointed by us for a series of debt securities will be named in the applicable prospectus supplement.

     Unless we tell you otherwise in the applicable prospectus supplement, if any payment date is not a business day, payments scheduled to be made on such payment date may be made on the next succeeding business day without additional interest.

     We may at any time designate additional paying agents or rescind the designation of any paying agents, except that, if debt securities of a series are issuable as registered securities, we will be required to maintain at least one paying agent in each place of payment designated for such series and, if debt securities of a series are issuable as bearer securities, we will be required to maintain a paying agent in a place of payment outside the United States where debt securities of such series and any related coupons may be presented and surrendered for payment. (Section 9.2 of the indenture)

     Unless we tell you otherwise in the applicable prospectus supplement, any moneys or governmental obligations (including the proceeds thereof) deposited with the trustee or any paying agent, or then held by us in trust, for the payment of the principal of, premium, if any, or interest or other amounts on any debt security that remains unclaimed for two years after such principal, premium, if any, or interest or other amounts has become due and payable will, at our request, be repaid to us. After repayment to us, holders of such debt securities will be entitled to seek payment only from us as a general unsecured creditor.

11

Notices

     AMR and the trustee will send notices regarding debt securities in registered form only to registered holders, using their addresses as listed in the registrar’s records. If you are not the holder of debt securities in registered form, you should consult the broker, bank or other financial intermediary through which you invest in such debt securities for information on how you will receive such notices. Holders of bearer debt securities will be notified by publication as described in the prospectus supplement relating to such debt securities. (Section 1.6 of the indenture)

Redemption

     Unless we state otherwise in an applicable prospectus supplement, debt securities will not be subject to any sinking fund.

     The redemption features, if any, of any series of debt securities will be described in the applicable prospectus supplement. We may redeem debt securities in denominations larger than $1,000 but, unless we state otherwise in an applicable prospectus supplement, only in integral multiples of $1,000

     Unless we state otherwise in an applicable prospectus supplement, we will mail notice of any redemption of debt securities at least 15 days but not more than 60 days before the redemption date to the holders. Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the debt securities or the portions called for redemption.

Consolidation, Merger or Sale by AMR

     The indenture generally permits AMR to consolidate or merge with or into another entity and to sell or otherwise dispose of all or substantially all of its assets. However, we may not take any of these actions unless all the following conditions are met:

     The remaining or acquiring person after any such transaction will be substituted for AMR under the indenture and the debt securities, and all obligations of AMR will terminate. (Section 7.1 of the indenture)

Events of Default, Notice and Certain Rights on Default

     The term “event of default” means, with respect to debt securities of any series, any of the following:

12

(Section 5.1 of the indenture) An event of default for a particular series of debt securities will not necessarily constitute an event of default for any other series of debt securities.

     The indenture requires the trustee to notify holders of the applicable series of debt securities of any uncured default within 90 days after such default occurs. The trustee may withhold notice, however, of any default (except in the payment of principal or interest) if it considers such withholding of notice to be in the holders’ best interests. (Section 6.5 of the indenture)

     If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in aggregate principal amount of the debt securities of the affected series may declare the entire principal amount (or, if the debt securities of that series are original issue discount debt securities or debt securities payable in accordance with an index, formula or other method, such portion of the principal amount or other amount specified in the prospectus supplement) of all the debt securities of that series to be due and immediately payable. (Section 5.2 of the indenture) The holders of a majority in aggregate principal amount of the debt securities of the affected series may waive, on behalf of the holders of all debt securities of such series, any past default or event of default with respect to that series and its consequences, except a default or event of default in the payment of the principal of or premium, if any, or interest, if any, on any debt security and certain other defaults. (Section 5.7 of the indenture)

     The holders of a majority in aggregate principal amount of the debt securities of the affected series (with the debt securities of each such series voting as a class) may direct the time, method and place of conducting any proceeding for any remedy available to the trustee for such series, or exercising any trust or power conferred on such trustee with respect to the debt securities of such series, as long as such direction does not conflict with any law or the indenture and subject to certain other limitations, including, if requested by the trustee, the provision of security or indemnity satisfaction to the trustee. (Section 5.8 of the indenture)

     Before a holder can bypass the trustee and bring its own lawsuit or other formal legal action or take other steps to enforce its rights or protect its interests relating to the debt securities, the following must occur:

(Section 5.9 of the indenture)

     However, a direct holder is entitled to bring a lawsuit at any time for the payment of principal, premium, if any, and interest due on its debt securities after the due date. (Section 5.10 of the indenture)

     If you are not the holder of debt securities in registered form, you should consult the broker, bank or financial intermediary through which you invest in such debt securities for information on your rights in respect of those debt securities following an event of default.

     We will file annually with the trustee a certificate as to AMR’s compliance with all conditions and covenants of the indenture. (Section 9.7 of the indenture)

Modification of the Indenture

     There are three categories of changes we can make to the indenture and the debt securities.

13

     Changes Requiring Approval of Each Affected Holder. First, there are changes that cannot be made to the indenture and the debt securities of any series without the approval of each holder of such debt securities who would be affected by such change. Following is a summary of those changes:

(Section 8.2 of the indenture)

     Changes Not Requiring Approval. The second category of changes to the indenture and the debt securities does not require any vote by holders of debt securities. Following is a summary of those changes:

14

(Section 8.1 of the indenture)

     Changes Requiring a Majority Vote. The third category of changes to the indenture and the debt securities requires a vote in favor by holders of debt securities owning a majority of the principal amount of each particular series adversely affected. This category includes other changes to the indenture and debt securities not part of the first and second categories of changes to the indenture and debt securities described above. (Section 8.2 of the indenture)

     If you are not the holder of debt securities in registered form, you should consult with the broker, bank or financial intermediary through which you invest in such debt securities for information on how approval will be granted or denied if we seek to change the indenture or request a waiver of any of its terms.

Satisfaction and Discharge

     The indenture provides that when, among other things, all debt securities of a series not previously delivered to the trustee for cancellation:

Defeasance

     Unless we tell you otherwise in the applicable prospectus supplement, the following discussion of full defeasance and covenant defeasance will apply to each series of debt securities. (Article IV of the indenture)

     Full Defeasance. Under certain circumstances, we can legally release ourselves from any payment or other obligations on the debt securities of any series (called “full defeasance”) if we put in place the following arrangements for the holders of those debt securities to be repaid:

15

(Sections 4.4 and 4.6 of the indenture)

     If we ever did accomplish full defeasance, as described above, holders would have to rely solely on the trust deposit for repayment on the debt securities of the particular series defeased. Holders could not look to AMR or any American Airlines, Inc. guarantee for repayment if a shortfall occurred.

     AMR may exercise its full defeasance option even if it has previously exercised its covenant defeasance option. If AMR exercises its full defeasance option, payment of the particular series of debt securities defeased may not be accelerated because of a default or an event of default. (Section 4.4 of the indenture)

     Covenant Defeasance. Under certain circumstances, we can make the same type of deposit described above and be released from some of the restrictive covenants in the debt securities of any series. This is called “covenant defeasance”. In that event, holders of those debt securities would lose the protection of those restrictive covenants but would gain the protection of having money and certain governmental obligations set aside in trust to repay such debt securities. To achieve covenant defeasance, we must do the following:

(Sections 4.5 and 4.6 of the indenture)

     If AMR exercises its covenant defeasance option with respect to the debt securities of a series, certain restrictive covenants of the indenture and certain events of default would no longer apply to such series. (Section 4.5 of the indenture) If one of the remaining events of default occurred, however, and payment of the debt securities of such series was accelerated, there could be a shortfall between the amount in the trust deposit at that time and the amount then due on such series. Holders could still look to AMR for payment of such debt securities if there were such a shortfall. Depending on the event causing the default (such as AMR’s bankruptcy), however, holders may not be able to obtain payment of the shortfall from AMR.

Conversion or Exchange

     We may convert or exchange the debt securities of a series into common stock or other securities. If so, we will describe the specific terms on which the debt securities may be converted or exchanged in the applicable prospectus supplement. The conversion or exchange may be mandatory, at your option, or at our option. The applicable prospectus supplement will describe the manner in which the shares of common stock or other securities you would receive would be converted or exchanged.

Guarantee of American Airlines, Inc.

     American Airlines, Inc. may guarantee unconditionally our obligations under any series of debt securities and the indenture as described in the applicable prospectus supplement. If American Airlines, Inc. guarantees these obligations under any series of debt securities, we will tell you in the applicable prospectus supplement and describe the terms of the guarantee in such prospectus supplement. Unless we tell you otherwise in the applicable prospectus supplement, such guarantee will be enforceable without any need to first enforce the debt securities against AMR, and will be an unsecured obligation of American Airlines, Inc.

The Trustee

     Wilmington Trust Company is the trustee under the indenture. Wilmington Trust Company acts as trustee with respect to certain other financing transactions of ours and of our affiliates. Wilmington Trust Company may from time to time provide banking or other services to us and our affiliates.

16

DESCRIPTION OF CAPITAL STOCK OF AMR CORPORATION

     We may elect to offer common stock or preferred stock. AMR’s certificate of incorporation, as amended (the “Certificate of Incorporation”) authorizes us to issue 750,000,000 shares of common stock, par value $1.00 per share, and 20,000,000 shares of preferred stock, without par value. On October 21, 2003, 159,347,481 shares of our common stock were outstanding. Our common stock currently is listed on the New York Stock Exchange under the trading symbol “AMR”. No shares of our preferred stock are outstanding as of the date hereof.

     The description of our capital stock in this prospectus is a summary. When we offer to sell capital stock, we will summarize in a prospectus supplement the particular terms of such capital stock that we believe will be the most important to your decision to invest in such capital stock. As the terms of such capital stock may differ from the summary in this prospectus, the summary in this prospectus is subject to and qualified by reference to the summary in such prospectus supplement, and you should rely on the summary in such prospectus supplement instead of the summary in this prospectus if the summary in such prospectus supplement is different from the summary in this prospectus. You should keep in mind, however, that it is the Certificate of Incorporation and our by-laws, as amended (the “By-Laws”), and statutory and common law, including the Delaware General Corporation Law (the “DGCL”), and not the summaries in this prospectus or such prospectus supplement, which define your rights as a holder of such capital stock. There may be other provisions in the Certificate of Incorporation and By-Laws that are also important to you. You should carefully read these documents for a full description of the terms of such capital stock. Our Certificate of Incorporation and By-Laws are incorporated by reference as exhibits to the registration statement that includes this prospectus. See “Where You Can Find More Information” for information on how to obtain copies of our Certificate of Incorporation and By-Laws.

Common Stock

     Voting Rights. The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Except as otherwise provided by law, the holders of our common stock vote as one class. The shares of our common stock do not have cumulative voting rights. As a result, subject to the voting rights, if any, of the holders of any shares of our preferred stock which may at the time be outstanding, the holders of common stock entitled to exercise more than 50% of the voting rights in an election of directors can elect 100% of the directors to be elected if they choose to do so. In such event, the holders of the remaining shares of our common stock voting for the election of directors will not be able to elect any persons to the board of directors.

     Delaware General Corporation Law Section 203. As a corporation organized under the laws of the State of Delaware, we are subject to Section 203 of the DGCL which restricts certain business combinations between us and an “interested stockholder” (in general, a stockholder owning 15% or more of our outstanding voting stock) or its affiliates or associates for a period of three years following the date on which the stockholder becomes an “interested stockholder”. The restrictions do not apply if (i) prior to an interested stockholder becoming such, the board of directors approves either the business combination or the transaction in which the stockholder becomes an interested stockholder, (ii) upon consummation of the transaction in which any person becomes an interested stockholder, such interested stockholder owns at least 85% of our voting stock outstanding at the time the transaction commences (excluding shares owned by certain employee stock ownership plans and persons who are both directors and officers of AMR) or (iii) on or subsequent to the date an interested stockholder becomes such, the business combination is both approved by the board of directors and authorized at an annual or special meeting of our stockholders, not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock not owned by the interested stockholder.

     Liquidation Rights and Other Provisions. Subject to the prior rights of creditors and the holders of any preferred stock which may be outstanding from time to time, the holders of our common stock are entitled in the event of liquidation, dissolution or winding up to share pro rata in the distribution of all remaining assets.

     The holders of our common stock are entitled to such dividends as our board of directors may declare from time to time from legally available funds subject to the preferential rights of the holders of any shares of our preferred stock that we may issue in the future. See “Dividend Policy”.

     The common stock is not liable to any calls or assessments and is not convertible into any other securities. The Certificate of Incorporation provides that the private property of the stockholders shall not be subject to the payment

17

of corporate debts. There are no redemption or sinking funds provisions applicable to the common stock, and the Certificate of Incorporation provides that there shall be no preemptive rights.

     The Certificate of Incorporation provides that our directors shall not be personally liable to AMR or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to AMR or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit. Section 174 of the DGCL specifies conditions under which directors of Delaware corporations may be liable for unlawful dividends or unlawful stock purchases or redemptions.

     The transfer agent and registrar for the common stock is EquiServe Trust Company, N.A.

Preferred Stock

     Subject to the limitations prescribed by the DGCL, the Certificate of Incorporation authorizes our board of directors to provide for the issuance of shares of preferred stock, from time to time, in one or more series, and to fix any voting powers, full or limited, and the designation, preferences and relative, participating, optional or other special rights, applicable to the shares to be included in any such series and any qualifications, limitations or restrictions thereon.

     A prospectus supplement will describe specific terms of the series of preferred shares then being offered. These terms may include some or all of the following:

18

     Unless we tell you otherwise in the applicable prospectus supplement, preferred shares will not be listed on any securities exchange.

     Unless otherwise specified in the prospectus supplement, the preferred shares will, with respect to dividend rights and rights upon our liquidation, dissolution or winding up, rank:

     The applicable prospectus supplement will specify the transfer agent and registrar for any shares of preferred stock we may offer pursuant to this prospectus.

19

DESCRIPTION OF DEPOSITARY SHARES

General Terms

     We may elect to offer depositary shares representing receipts for fractional interests in debt securities or preferred stock. In this case, we will issue receipts for depositary shares, each of which will represent a fraction of a debt security or share of a particular series of preferred stock (or a combination thereof), as the case may be. We will deposit the debt securities or shares of any series of preferred stock represented by depositary shares under a deposit agreement between us and a depositary, which we will name in the applicable prospectus supplement. Subject to the terms of the deposit agreement, as an owner of a depositary share you will be entitled, in proportion to the applicable fraction of a debt security or share of preferred stock represented by the depositary share, to all the rights and preferences of the debt security or preferred stock, as the case may be, represented by the depositary share, including, as the case may be, interest, dividend, voting, conversion, redemption, sinking fund, repayment at maturity, subscription and liquidation rights.

     The description of our depositary shares in this prospectus is a summary. When we offer to sell depositary shares, we will summarize in a prospectus supplement the particular terms of such depositary shares and the applicable deposit agreement that we believe will be the most important to your decision to invest in such depositary shares. As the terms of such depositary shares may differ from the summary in this prospectus, the summary in this prospectus is subject to and qualified by reference to the summary in such prospectus supplement, and you should rely on the summary in such prospectus supplement instead of the summary in this prospectus if the summary in such prospectus supplement is different from the summary in this prospectus. You should keep in mind, however, that it is the depositary shares, the deposit agreement and the indenture (in the case of depositary shares representing fractional interests in debt securities), or the Certificate of Incorporation and By-Laws (in the case of depositary shares representing fractional interests in preferred stock) and not the summaries in this prospectus or such prospectus supplement, which define your rights as a holder of such depositary shares. There may be other provisions in these documents that are also important to you. You should carefully read these documents for a full description of the terms of such depositary shares. A copy of the form of deposit agreement will be filed with the SEC as an exhibit to a report on Form 8-K or by a post-effective amendment to the registration statement that includes this prospectus. See “Where You Can Find More Information” for information on how to obtain copies of this document.

Interest, Dividends and Other Distributions

     The depositary will distribute all payments of interest, cash dividends or other cash distributions received on the debt securities or preferred stock, as the case may be, to you in proportion to the number of depositary shares that you own.

     In the event of a distribution other than in cash, the depositary will distribute property received by it to you in an equitable manner, unless the depositary determines that it is not feasible to make a distribution. In that case the depositary may sell the property and distribute the net proceeds from the sale to you.

Redemption of Depositary Shares

     If we redeem a debt security or series of preferred stock represented by depositary shares, the depositary will redeem your depositary shares from the proceeds received by the depositary resulting from the redemption. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per debt security or share of preferred stock, as the case may be, payable in relation to the redeemed series of debt securities or preferred stock. Whenever we redeem debt securities or shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing, as the case may be, the debt securities or shares of preferred stock redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot, proportionately or by any other equitable method as the depositary may determine.

Exercise of Rights under the Indenture or Voting the Preferred Stock

     Upon receipt of notice of any meeting at which you are entitled to vote, or of any request for instructions or directions from you as holder of debt securities, the depositary will mail to you the information contained in that

20

notice. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary how to give instructions or directions with respect to the debt securities represented by that holder’s depositary shares or how to vote the amount of the preferred stock represented by that holder’s depositary shares. The record date for the depositary shares will be the same date as the record date for the debt securities or preferred stock, as the case may be. The depositary will endeavor, to the extent practicable, to give instructions or directions with respect to the debt securities or to vote the amount of the preferred stock, as the case may be, represented by the depositary shares in accordance with those instructions. We will agree to take all reasonable action which the depositary may deem necessary to enable the depositary to do so. The depositary will abstain from giving instructions or directions with respect to the debt securities or voting shares of the preferred stock, as the case may be, represented by your depositary shares if it does not receive specific instructions from you.

Amendment and Termination of the Deposit Agreement

     We and the depositary may amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement at any time. However, any amendment which materially and adversely alters the rights of the holders of the depositary shares will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding.

     The deposit agreement will terminate if:

Resignation and Removal of Depositary

     The depositary may resign at any time by delivering to us notice of its election to do so. We also may, at any time, remove the depositary. Any resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. We must appoint the successor depositary within 60 days after delivery of the notice of resignation or removal. The successor depositary must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

Charges of Depositary

     We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the debt securities or preferred stock, as the case may be, and issuance of depositary receipts, all withdrawals of shares of debt securities or preferred stock, as the case may be, by you and any repayment or redemption of the debt securities or preferred stock, as the case may be. You will pay other transfer and other taxes and governmental charges, as well as the other charges that are expressly provided in the deposit agreement to be for your account.

Miscellaneous

     The depositary will forward all reports and communications from us which are delivered to the depositary and which we are required or otherwise determine to furnish to holders of debt securities or preferred stock, as the case may be.

     The depositary will not be obligated to prosecute or defend any legal proceedings relating to any depositary shares, debt securities or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, or upon information provided by persons presenting debt securities or shares of preferred stock for deposit, you or other persons believed to be competent and on documents which we and the depositary believe to be genuine.

21

Guarantee of American Airlines, Inc.

     American Airlines, Inc. may guarantee unconditionally our obligations under the depositary shares and the applicable deposit agreement as described in the applicable prospectus supplement. If American Airlines, Inc. guarantees these obligations, we will tell you in the applicable prospectus supplement and describe the terms of the guarantee in such prospectus supplement. Unless we tell you otherwise in the applicable prospectus supplement, such guarantee will be enforceable without any need to first enforce the depositary shares against AMR, and will be an unsecured obligation of American Airlines, Inc.

22

DESCRIPTION OF WARRANTS

     We may elect to offer warrants, including warrants to purchase debt securities, preferred stock, common stock or other securities, property or assets, as well as other types of warrants. We may issue warrants independently or together with any other securities, and they may be attached to or separate from those securities. We will issue the warrants under warrant agreements between us and a bank or trust company, as warrant agent, that we will describe in the prospectus supplement relating to the warrants that we offer.

     The description of our warrants in this prospectus is a summary. When we offer to sell warrants, we will summarize in a prospectus supplement the particular terms of such warrants and the applicable warrant agreement that we believe will be the most important to your decision to invest in such warrants. As the terms of such warrants may differ from the summary in this prospectus, the summary in this prospectus is subject to and qualified by reference to the summary in such prospectus supplement, and you should rely on the summary in such prospectus supplement instead of the summary in this prospectus if the summary in such prospectus supplement is different from the summary in this prospectus. You should keep in mind, however, that it is the warrant certificate relating to such warrants and the warrant agreement, and not the summaries in this prospectus or such prospectus supplement, which defines your rights as a holder of such warrants. There may be other provisions in the warrant certificate relating to such warrants and the warrant agreement that are also important to you. You should carefully read these documents for a full description of the terms of such warrants. Forms of these documents will be filed with the SEC as exhibits to a report on Form 8-K or by a post-effective amendment to the registration statement that includes this prospectus. See “Where You Can Find More Information” for information on how to obtain copies of these documents.

Debt Warrants

     We may offer warrants to purchase debt securities (“debt warrants”). A prospectus supplement will describe specific terms of the debt warrants, the warrant agreement relating to the debt warrants and the warrant certificates representing the debt warrants. These terms may include some or all of the following:

23

     We will also describe in the applicable prospectus supplement any provisions for a change in the exercise price or expiration date of the debt warrants and the kind, frequency and timing of any notice to be given. You may exchange warrant certificates for new warrant certificates of different denominations and you may exercise debt warrants at the corporate trust office of the warrant agent or any other office that we indicate in the applicable prospectus supplement. We will not charge any service charges for any transfer or exchange of warrant certificates, but we may require payment for tax or other governmental charges in connection with the exchange or transfer. Unless the prospectus supplement states otherwise, prior to exercise, you will not have any of the rights of holders of the debt securities purchasable upon that exercise and will not be entitled to payments of principal, premium, if any, or interest on the debt securities purchasable upon the exercise.

Other Warrants

     We may issue other warrants. A prospectus supplement will describe specific terms of the warrants, the warrant agreement relating to the warrants and the warrant certificates representing the warrants. These terms may include some or all of the following:

24

     We will also describe in the applicable prospectus supplement any provisions for a change in the exercise price or the expiration date of the warrants and the kind, frequency and timing of any notice to be given. You may exchange warrant certificates for new warrant certificates of different denominations and you may exercise warrants at the corporate trust office of the warrant agent or any other office that we indicate in the applicable prospectus supplement. We will not charge any service charges for any transfer or exchange of warrant certificates, but we may require payment for tax or other governmental charges in connection with the exchange or transfer. Unless the prospectus supplement states otherwise, prior to the exercise of your warrants, you will not have any of the rights of holders of the preferred stock, common stock or other securities, property or assets purchasable upon that exercise and will not be entitled to dividend payments, if any, or voting rights of the preferred stock, common stock or other securities purchasable upon the exercise.

Exercise of Warrants

     We will describe in the prospectus supplement relating to the warrants the principal amount, the number of our securities, or amount of other property or assets that you may purchase for cash upon exercise of a warrant, and the exercise price. You may exercise a warrant as described in the prospectus supplement relating to the warrants at any time up to the close of business on the expiration date stated in the prospectus supplement. Unexercised warrants will become void after the close of business on the expiration date, or any later expiration date that we determine.

     We will forward the securities, property or assets purchasable upon the exercise as soon as practicable after receipt of payment and the properly completed and executed warrant certificate at the corporate trust office of the warrant agent or other office stated in the applicable prospectus supplement. If you exercise less than all of the warrants represented by the warrant certificate, we will issue you a new warrant certificate for the remaining warrants.

Guarantee of American Airlines, Inc.

     American Airlines, Inc. may guarantee unconditionally our obligations under the warrants and the applicable warrant agreement as described in the applicable prospectus supplement. If American Airlines, Inc. guarantees these obligations, we will tell you in the applicable prospectus supplement and describe the terms of the guarantee in such prospectus supplement.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

     We may elect to offer, from time to time, stock purchase contracts, representing contracts obligating holders to purchase from us, and for us to sell to holders, a specific number of shares of common stock or preferred stock, or other securities, property or assets, at a future date or dates. We may issue stock purchase contracts separately or as a part of stock purchase units.

     The description of our stock purchase contracts and stock purchase units in this prospectus is a summary. When we offer to sell a series of stock purchase contracts or stock purchase units, we will summarize in a prospectus supplement the particular terms of such series of stock purchase contracts or stock purchase units, as the case may be, that we believe will be the most important to your decision to invest in such series. As the terms of such series of stock purchase contracts or stock purchase units, as the case may be, may differ from the summary in this prospectus, the summary in this prospectus is subject to and qualified by reference to the summary in such prospectus supplement, and you should rely on the summary in such prospectus supplement instead of the summary in this prospectus if the summary in such prospectus supplement is different from the summary in this prospectus. You should keep in mind, however, that it is the stock purchase contract or stock purchase unit, as the case may be, and, if applicable, any related collateral arrangements and depositary arrangements, and not the summaries in this prospectus or such prospectus supplement, which defines your rights as a holder of such series of stock purchase contracts or stock purchase units, as the case may be. There may be other provisions in the stock purchase contract or stock purchase unit, and the related collateral arrangements and depositary arrangements, if any, that are also important to you. You should carefully read these documents for a full description of the terms of the stock purchase contracts and stock purchase units. Forms of these documents will be filed with the SEC as exhibits to a report on Form 8-K or by a post-effective amendment to the registration statement that includes this prospectus. See “Where You Can Find More Information” for information on how to obtain copies of these documents.

     The price per share of preferred stock or common stock or the price of any other securities, property or assets, as the case may be, subject to any stock purchase contracts may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula described in the stock purchase contracts. The stock purchase units are expected to consist of the following:

The stock purchase contracts may require us to make periodic payments to holders of the stock purchase units, or may require the holders of the stock purchase units to make periodic payments to us. Any such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations under the stock purchase contract in a specified manner.

Guarantee of American Airlines, Inc.

     American Airlines, Inc. may guarantee unconditionally our obligations under the stock purchase contracts or stock purchase units and, if applicable, collateral arrangements and depositary arrangements, as described in the applicable prospectus supplement. If American Airlines, Inc. guarantees these obligations, we will tell you in the applicable prospectus supplement and describe the terms of the guarantee in such prospectus supplement. Unless we tell you otherwise in the applicable prospectus supplement, such guarantee will be enforceable without any need to first enforce the stock purchase contracts or stock purchase units, as the case may be, against AMR, and will be an unsecured obligation of American Airlines, Inc.

26

PLAN OF DISTRIBUTION

     We may sell securities from time to time in one or more transactions. We may sell the securities of or within any series to or through agents, underwriters or dealers or directly to one or more purchasers.

Agents

     We may use agents to sell securities. We will name any agent involved in offering or selling securities, and disclose any commissions that we will pay to the agent, in the applicable prospectus supplement. Unless we tell you otherwise in the applicable prospectus supplement, the agents will agree to use their reasonable best efforts to solicit purchases for the period of their appointment. Our agents may be deemed to be underwriters under the Securities Act of any of the securities that they offer or sell.

Underwriters

     We may sell securities to underwriters. Unless we tell you otherwise in the applicable prospectus supplement, the underwriters may resell those securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Unless the applicable prospectus supplement states otherwise, the obligations of the underwriters to purchase any series of securities will be subject to conditions precedent, and the underwriters will be obligated to purchase all of the securities if any are purchased. The underwriters may change any initial public offering price and any discounts or concessions they give to dealers.

Direct Sales

     We may solicit directly offers to purchase the securities, and we may sell securities directly to purchasers without the involvement of underwriters or agents. We will describe the terms of our direct sale in the applicable prospectus supplement.

Dealers

     We may use a dealer to sell the securities. If we use a dealer, we, as principal, will sell the securities to the dealer who will then sell the securities to the public at varying prices that the dealer will determine at the time it sells our securities.

Other Means of Distribution

     Securities may also be offered and sold, if we so indicate in the applicable prospectus supplement, by one or more firms (“remarketing firms”) acting as principals for their own accounts or as our agents in connection with a remarketing of such securities following their purchase or redemption. Remarketing firms may be deemed to be underwriters under the Securities Act in connection with the securities they remarket.

Delayed Delivery Contracts

     We may authorize our agents and underwriters to solicit offers by certain institutions to purchase the securities at the public offering price under delayed delivery contracts. If we use delayed delivery contracts, we will disclose that we are using them in the applicable prospectus supplement and will tell you when we will demand payment and delivery of the securities under the delayed delivery contracts. These delayed delivery contracts will be subject only to the conditions that we describe in the prospectus supplement.
