INFORMATION ABOUT ANHEUSER-BUSCH

     Anheuser-Busch Companies, Inc. (“Anheuser-Busch”) is a Delaware corporation that was organized in 1979 as the holding company parent of Anheuser-Busch, Incorporated (“ABI”), a Missouri corporation whose origins date back to 1875. In addition to ABI, which is one of the largest brewers globally, we are also the parent corporation to a number of subsidiaries that conduct various other business operations.

     These are our most important subsidiaries:

USE OF PROCEEDS

     Unless we indicate otherwise in the prospectus supplement which accompanies this Prospectus, we intend to add the net proceeds from the sale of the Debt Securities to our general funds. We expect to use the proceeds for general corporate purposes, including working capital, capital expenditures and repayment of borrowings. Before we use the proceeds for these purposes, we may invest them in short-term investments.

DESCRIPTION OF THE DEBT SECURITIES

     This section describes some of the general terms of the Debt Securities. The prospectus supplement describes the particular terms of the Debt Securities we are offering. The prospectus supplement also indicates the extent, if any, to which these general provisions may not apply to the Debt Securities being offered. If you would like more information on these provisions, you may review the Indenture which is an exhibit to the Registration Statement which is filed with the SEC. See “Where You Can Find More Information” on page 2 of this Prospectus.

     We plan to issue the Debt Securities under the Indenture dated as of July 1, 2001 between us and JPMorgan Chase Bank, formerly The Chase Manhattan Bank, as Trustee. This Prospectus summarizes certain important provisions of the Debt Securities and the Indenture. This is not a complete description of the important terms. You should refer to the specific terms of the Indenture for a complete statement of the terms of the Indenture and the Debt Securities. When we use capitalized terms which we do not define here, those terms have the meanings given to them in the Indenture. When we use references to Sections, we mean Sections in the Indenture.

     We may also issue Debt Securities under a separate, new indenture, substantially identical to the Indenture, to be entered into between us and a new trustee. If that occurs, we will describe any differences in the terms of any series or issue of Debt Securities in the prospectus supplement relating to that series or issue.

General

     The Debt Securities will be senior unsecured obligations of Anheuser-Busch.

     We may issue Securities under the Indenture, including the Debt Securities, at various times in one or more series and issues. As of the date of this Prospectus, there is approximately $3.65 billion in principal amount of securities outstanding under the Indenture. The Indenture does not limit the amount of Securities that we may issue under the Indenture, nor does it limit other debt that we may issue.

     We may issue the Debt Securities at various times in different series and issues, each of which may have different terms. The word “issue” means, for any series of Securities, that the Securities have the same original issue date or date from which interest starts to accrue, the same maturity date and the same interest rate and other payment terms or that we have otherwise designated Securities as part of the same issue. Unless we indicate otherwise in the prospectus supplement for any series of Debt Securities, we may treat a subsequent offering of Securities as a part of the same issue as that series.

     The prospectus supplement relating to the particular series or issue of Debt Securities we are offering includes the following information concerning those Debt Securities:

Payments on Debt Securities; Transfers

     We will make payments on the Debt Securities to the persons in whose names the securities are registered at the close of business on the record date for the interest payments. As explained under “Book-Entry Securities” below, The Depository Trust Company or its nominee will be the initial registered holder unless the prospectus supplement provides otherwise.

     Unless we indicate otherwise in the prospectus supplement for any series or issue of Debt Securities, we will make payments on the Debt Securities at the Trustee’s office. For JPMorgan Chase Bank, the office is now its Institutional Trust Services office, 4 New York Plaza, New York, New York 10004. In the case of any other Trustee, we will specify the office and address in the related prospectus supplement. Transfers of Debt Securities can be made at the same offices. (Sections 202, 301, 306 and 1002)

Form and Denominations

     Unless we otherwise indicate in the prospectus supplement for any series or issue of Debt Securities:

Certain Restrictions

     Creation of Secured Indebtedness

     Under the Indenture, we and our Restricted Subsidiaries (defined below) may not create, assume, guarantee or permit to exist any indebtedness for borrowed money which is secured by a pledge of, or a mortgage or lien on, any of our Principal Plants (defined below) or on any of our Restricted Subsidiaries’ capital stock, unless we also provide equal and ratable security for the Securities outstanding under the Indenture. A “Restricted Subsidiary” is a Subsidiary which owns or operates a Principal Plant, unless it is incorporated or has its principal place of business outside the United States, and any other subsidiary which we elect to treat as a Restricted Subsidiary. A “Principal Plant” is a brewery, or a manufacturing, processing or packaging plant located in the United States, but does not include a plant which we determine is not of material importance to the total business conducted by us and our Subsidiaries, any plant which we determine is used primarily for transportation, marketing or warehousing or at our option

-5-

any plant that does not constitute part of the brewing operations of the Company and has a net book value of not more than $100,000,000.

     This restriction does not apply to:

     There is an additional exception as described below under “10% Basket Amount.”

     If we become obligated to provide security for the Securities as described above, we would also be required to provide comparable security for most of our other outstanding long-term indebtedness.

     Sale–Leaseback Financings

     Under the Indenture, neither we nor any Restricted Subsidiary may enter into any sale and leaseback transaction involving a Principal Plant, except a sale by a Restricted Subsidiary to us or another Restricted Subsidiary or a lease not exceeding three years, by the end of which we intend to discontinue use of the property, and except for any transaction with a local or state authority that provides financial or tax benefits, unless:

     There is an additional exception as described below under “10% Basket Amount.”

     Limitation on Funded Debt of Restricted Subsidiaries

     We may not permit any Restricted Subsidiary to create, assume or permit to exist any Funded Debt other than:

-6-

     There is an additional exception as described below under “10% Basket Amount.”

     “Funded Debt” means all indebtedness for money borrowed, including purchase money indebtedness, having a maturity of more than twelve months from the date of determination or having a maturity of less than twelve months but by its terms being renewable or extendible beyond twelve months at the borrower’s option, subject only to conditions which the borrower is then capable of fulfilling, and direct guarantees of similar indebtedness for money borrowed of others and any other indebtedness classified as long-term indebtedness in the financial statements of the borrower, except that Funded Debt does not include:

     10% Basket Amount

     In addition to the exceptions described above under “Creation of Secured Indebtedness,” “Sale–Leaseback Financings” and “Limitation on Funded Debt of Restricted Subsidiaries,” the Indenture allows additional secured indebtedness, additional sale–leaseback financings and additional Funded Debt of Restricted Subsidiaries as long as the total of the additional indebtedness and Funded Debt and the fair market value of the property transferred in the additional sale–leaseback financings does not exceed 10% of our Net Tangible Assets. “Net Tangible Assets” means our total assets including those of our subsidiaries after deducting current liabilities (except for those which are Funded Debt) and goodwill, trade names, trademarks, patents, unamortized debt discount and expense, organization and developmental expenses and other like segregated intangibles. Deferred income taxes, deferred investment tax credit or other similar items will not be considered as a liability or as a deduction from or adjustment to total assets. (Sections 1006(d), 1007(c) and 1008(b))

     Merger

     We may consolidate with or merge into any other corporation or transfer or lease our properties and assets substantially as an entirety as long as we meet certain conditions, including the assumption of the Securities by any successor corporation. (Section 801) The Company is not restricted from transferring its aluminum can manufacturing business and related operations.

Modification or Amendment of the Indenture

     We may modify and amend the Indenture if the holders of a majority in principal amount of the outstanding Securities affected by the modification or amendment consent, except that no supplemental indenture may reduce the principal amount of or interest or premium payable on any Security, change the maturity date or dates of principal payments, the interest payment dates or other terms of payment, or reduce the percentage of holders necessary to approve a modification or amendment of the Indenture,

-7-

without the consent of each holder of outstanding Securities affected by the supplemental indenture. (Section 902)

     We and the Trustee may amend the Indenture without the holders’ consent for certain specified purposes, including any change which, in our counsel’s opinion, does not materially adversely affect the holders’ interests. (Section 901)

Defeasance

     The Indenture includes provisions allowing defeasance of the Debt Securities of any series. In order to defease a series of Debt Securities, we would deposit with the Trustee or another trustee money or U.S. Government Obligations sufficient to make all payments on those Debt Securities. If we make a defeasance deposit with respect to a series of Debt Securities, we may elect either:

     To establish the trust, we must deliver to the Trustee an opinion of our counsel that the holders of that series of Debt Securities will not recognize gain or loss for Federal income tax purposes as a result of the defeasance and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if the defeasance had not occurred. (Article Thirteen)

Events of Default, Notice and Waiver

     An Event of Default in respect of any issue of Securities means:

     If an Event of Default occurs and is continuing in respect of any series or issue of Securities, either the Trustee or the holders of 25% in principal amount of such Securities then outstanding may declare the principal of and accrued interest, if any, on all Securities of those issues to be due and payable. If other specified Events of Default occur and are continuing, either the Trustee or the holders of 25% in principal amount of the outstanding Securities may declare the principal of and accrued interest, if any, on all the outstanding Securities to be due and payable. (Section 502)

     Within 90 days after a default in respect of any issue of Securities, the Trustee must give to the holders of the Securities of that issue notice of all uncured and unwaived defaults by us known to it; however, except in the case of default in payment, the Trustee may withhold the notice if it in good faith determines that it is in the interest of the holders. The term “default” means, for this purpose, the occurrence of any event that is or, upon notice or lapse of time would be, an Event of Default. (Section 602)

     Before the Trustee is required to exercise rights under the Indenture at the request of holders, it is entitled to be indemnified by the holders, subject to its duty, during an Event of Default, to act with the required standard of care. (Article Six)

-8-

     A holder of a Security will not be entitled to pursue any remedy under the Indenture except under the following circumstances:

     The holders of a majority in principal amount of the outstanding Securities of any series (voting as a single class) may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred upon the Trustee in respect of the securities of that series. (Section 512)

     The holders of a majority in principal amount of the outstanding Securities of all series affected by a default (voting as a single class) may, on behalf of the holders of all those Securities, waive the default except a default in payment of the principal of or premium, if any, or interest on any Security. (Section 513) The holders of a majority in principal amount of outstanding Securities of all series entitled to the benefits thereof (voting as a single class) may waive compliance with certain covenants under the Indenture. (Section 1010)

     We will furnish to the Trustee, annually, a statement as to the fulfillment by us of our obligations under the Indenture. (Section 1004)

Regarding the Trustee

     JPMorgan Chase Bank is the Trustee under the Indenture. The Indenture is dated as of July 1, 2001. JPMorgan Chase Bank also acts as trustee (or successor trustee) under other indentures with us under which an aggregate of approximately $2.9 billion in principal amount of indebtedness is issued and outstanding as of the date of this Prospectus. JPMorgan Chase Bank and its affiliates also are parties to our credit agreement, under which they have committed to lend us up to $500 million, and they provide other commercial banking services to us. Affiliates of JPMorgan Chase Bank have engaged, and may in the future engage, in investment banking and/or general financing and banking transactions with us.

     We can remove the Trustee of any series as long as there is no Event of Default and no event that, upon notice or lapse of time or both, would become an Event of Default. The holders of a majority of the principal amount of the Securities of any series may also remove the Trustee at any time. The Indenture prescribes procedures by which the Trustee will be replaced, in the event of its removal. (Section 610)

-9-

BOOK-ENTRY DEBT SECURITIES

     The prospectus supplement will indicate whether we are issuing the related Debt Securities as book-entry securities. Book-entry securities of a series will be issued in the form of one or more global notes that will be deposited with The Depository Trust Company, New York, New York, and will evidence all of the Debt Securities of that series. This means that we will not issue certificates to each holder. We will issue one or more global securities to DTC, which will keep a computerized record of its participants (for example, your broker) whose clients have purchased the Debt Securities. The participant will then keep a record of its clients who own the Debt Securities. Unless it is exchanged in whole or in part for a security evidenced by individual certificates, a global security may not be transferred, except that DTC, its nominees and their successors may transfer a global security as a whole to one another. Beneficial interests in global securities will be shown on, and transfers of beneficial interests in global notes will be made only through, records maintained by DTC and its participants. Each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if the person is not a participant, on the procedures of the participant through which the person owns its interest to exercise any rights of a holder of Debt Securities under the Indenture.

     The laws of some jurisdictions require that certain purchasers of securities such as Debt Securities take physical delivery of the securities in definitive form. These limits and laws may impair your ability to acquire or transfer beneficial interests in the global security.

     We will make payments on each series of book-entry Debt Securities to DTC or its nominee, as the sole registered owner and holder of the global security. Neither Anheuser-Busch, the Trustee nor any of their agents will be responsible or liable for any aspect of DTC’s records relating to or payments made on account of beneficial ownership interests in a global security or for maintaining, supervising or reviewing any of DTC’s records relating to the beneficial ownership interests.

     DTC has advised us that, when it receives any payment on a global security, it will immediately, on its book-entry registration and transfer system, credit the accounts of participants with payments in amounts proportionate to their beneficial interests in the global security as shown on DTC’s records. Payments by participants to you, as an owner of a beneficial interest in the global security, will be governed by standing instructions and customary practices (as is now the case with securities held for customer accounts registered in “street name”) and will be the sole responsibility of the participants.

     A global security representing a series will be exchanged for certificated Debt Securities of that series if (a) DTC notifies us that it is unwilling or unable to continue as Depositary or if DTC ceases to be a clearing agency registered under the Securities Exchange Act of 1934 and we do not appoint a successor within 90 days or (b) we decide that the global security shall be exchangeable. If that occurs, we will issue Debt Securities of that series in certificated form in exchange for the global security. An owner of a beneficial interest in the global security then will be entitled to physical delivery of a certificate for Debt Securities of the series equal in principal amount to that beneficial interest and to have those Debt Securities registered in its name. We would issue the certificates for the Debt Securities in denominations of $1,000 and any integral multiple thereof, and in registered form only without coupons, unless otherwise specified in the related prospectus supplement.

     DTC has informed us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds securities that its participants (known as direct participants) deposit with DTC. DTC also facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to the DTC system

-10-

is also available to others, known as indirect participants, such as securities brokers and dealers, banks, trust companies and clearing corporations that clear transactions through or maintain a custodial relationship with a direct participant. The rules applicable to DTC and its participants are on file with the SEC.

PLAN OF DISTRIBUTION

     We may sell Debt Securities to or through one or more underwriters or dealers, and also may sell Debt Securities directly to other purchasers or through agents. These firms may also act as our agents in the sale of Debt Securities. Only underwriters named in the prospectus supplement will be considered as underwriters of the Debt Securities offered by the prospectus supplement.

     We may distribute Debt Securities at different times in one or more transactions. We may sell Debt Securities at fixed prices, which may change, at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices.

     In connection with the sale of Debt Securities, underwriters may receive compensation from us or from purchasers of Debt Securities in the form of discounts, concessions or commissions. Underwriters, dealers and agents that participate in the distribution of Debt Securities may be deemed to be underwriters. Discounts or commissions they receive and any profit on their resale of Debt Securities may be considered underwriting discounts and commissions under the Securities Act of 1933. We will identify any underwriter or agent, and we will describe any compensation, in the prospectus supplement.

     We may agree to indemnify underwriters, dealers and agents who participate in the distribution of Debt Securities against certain liabilities, including liabilities under the Securities Act of 1933.

     We may authorize dealers or other persons who act as our agents to solicit offers by certain institutions to purchase Debt Securities from us under contracts which provide for payment and delivery on a future date. We may enter into these contracts with commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others. If we enter into these agreements concerning any series of Debt Securities, we will indicate that in the prospectus supplement.

     In connection with an offering of Debt Securities, underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Debt Securities. Specifically, underwriters may over-allot in connection with the offering, creating a syndicate short position in the Debt Securities for their own account. In addition, underwriters may bid for, and purchase, Debt Securities in the open market to cover short positions or to stabilize the price of the Debt Securities. Finally, underwriters may reclaim selling concessions allowed for distributing the Debt Securities in the offering if the underwriters repurchase previously distributed Debt Securities in transactions to cover short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the Debt Securities above independent market levels. Underwriters are not required to engage in any of these activities and may end any of these activities at any time.

     Unless otherwise indicated in the prospectus supplement, each series of Debt Securities offered will be a new issue of securities and will have no established trading market. The Debt Securities may or may not be listed on a national securities exchange. No assurance can be given as to the liquidity of or the existence of trading markets for any Debt Securities.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

     The following table sets forth estimated expenses in connection with the issuance and distribution of the securities being registered, assuming six issuances of securities:

     The Delaware General Corporation Law permits the indemnification by a Delaware corporation of its directors, officers, employees and other agents against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than derivative actions which are by or in the right of the corporation) if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard of care is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys’ fees) incurred in connection with defense or settlement of such an action and requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

     The Registrant’s Restated Certificate of Incorporation provides that each person who was or is made a party to, or is involved in, any action, suit or proceeding by reason of the fact that he or she is or was a director or officer of the Registrant (or was serving at the request of the Registrant as a director, officer, employee or agent for another entity) while serving in such capacity will be indemnified and held harmless by the Registrant to the full extent authorized or permitted by Delaware law. The Restated Certificate also provides that the Registrant may purchase and maintain insurance and may also create a trust fund, grant a security interest and/or use other means (including establishing letters of credit, surety bonds and other similar arrangements) and may enter into contracts providing for indemnification, to ensure full payment of indemnifiable amounts.

     The Registrant has entered into indemnification agreements with its directors and executive officers.

* Filed previously.

     The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made of the securities registered hereby, a post-effective amendment to this registration statement (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that the undertakings set forth in subparagraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by the Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement.

     (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the

II-2

securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

     (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     (5) To file an application for the purpose of determining the eligibility of the trustee (under any Indenture entered into with a trustee to be selected) to act under subsection (a) of section 310 of the Trust Indenture Act (the “TIA”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the TIA.

     Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the provisions described under Item 15 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
