SELLING SHAREHOLDERS The selling shareholders will consist of the holders of shares of common stock acquired under the Plan who may be deemed "affiliates" for purposes of the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). The selling shareholders will be listed in a supplement to this prospectus. Such supplement will indicate any relationship which such selling shareholder has had with AIG for the three years preceding the date of such supplement and the number of shares which such selling shareholder intends to sell pursuant to this prospectus. PLAN OF DISTRIBUTION The shares of common stock may be sold from time to time by the selling shareholders, or by pledgees, donees, transferees or other successors in interest. Such sales may be made on the New York Stock Exchange, in the over-the-counter market or otherwise, at prices and at terms then prevailing or at prices related to the then current market price, or in negotiated transactions. The shares may be sold in one or more of the following transactions: - a block trade in which the broker-dealer so engaged will attempt to sell such shares as agent but may position and resell a portion of the block as principal to facilitate the transaction; - purchase of such shares by a broker-dealer as principal and resale by such broker-dealer for its account pursuant to this prospectus; - ordinary brokerage transactions and transactions in which the broker solicits purchasers. In effecting sales, broker-dealers engaged by the selling shareholders may arrange for other broker-dealers to participate in the resales. Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from selling shareholders in amounts to be negotiated in connection with the sales. Such broker-dealers and any other participating broker-dealers may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales and any such commission, discount or concession may be deemed to be underwriting discounts or commissions under the Securities Act. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus. Commissions and discounts, if any, attributable to the sales of the shares will be borne by the selling shareholders.

Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement. ITEM 4. DESCRIPTION OF SECURITIES The Common Stock is registered under Section 12(b) of the Exchange Act. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL The consolidated financial statements of AIG and its subsidiaries and the related financial statement schedules of AIG included in its most recent Annual Report on Form 10-K, incorporated herein by reference, are so incorporated in reliance upon the reports of PricewaterhouseCoopers LLP independent accountants, given on the authority of that firm as experts in accounting and auditing. The validity of the shares of Common Stock offered hereby will be passed upon by Kathleen E. Shannon, Esq., Associate General Counsel of AIG. Ms. Shannon is regularly employed by AIG, participates in various AIG employee benefit plans under which she may receive shares of Common Stock and currently beneficially owns less than 1% of the outstanding shares of Common Stock. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS The Restated Certificate of Incorporation of AIG (the "Certificate") provides that AIG shall indemnify to the full extent permitted by law any person made, or threatened to be made, a party to an action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that he, his testator or intestate is or was a director, officer or employee of the Company or serves or served any other enterprise at the request of AIG. Section 6.4 of AIG's By-laws contains a similar provision. The Certificate also provides that a director will not be personally liable to AIG or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that such an exemption from liability or limitation thereof is not permitted by the Delaware General Corporation Law (the "GCL"). Section 145 of the GCL permits indemnification against expenses, fines, judgments and settlements incurred by any director, officer or employee of the registrant in the event of pending or threatened civil, criminal, administrative or investigative proceedings, if such person was, or was threatened to be made, a party by reason of the fact that he is or was a director, officer or employee of AIG. Section 145 also provides that the indemnification provided for therein shall not be deemed exclusive of any other rights to which those seeking II-1

8 indemnification may otherwise be entitled. In addition, AIG and its subsidiaries maintain a directors' and officers' liability insurance policy. ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED Not applicable. ITEM 8. EXHIBITS The exhibits are listed in the exhibit index. ITEM 9. UNDERTAKINGS The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of this 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 this Registration Statement; (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 this Registration Statement; provided, however, that paragraphs (1)(i) and (1)(ii) 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 Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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. (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. The Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in this 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. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, 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 Securities 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 Securities Act and will be governed by the final adjudication of such issue.

1 EXHIBIT 5 June 23, 2000 American International Group, Inc. 70 Pine Street New York, New York 10270 Dear Sirs: In connection with the registration under the Securities Act of 1933, as amended (the "Act"), of 15,000,000 shares (the "Securities") of Common Stock, par value $2.50 per share (the "Common Stock"), of American International Group, Inc., a Delaware corporation (the "Company"), I, as Vice President and Associate General Counsel of the Company, have examined such corporate records, certificates and other documents, and such question of law, as I have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, I advise you that, in my opinion, with respect to the Securities (the "Option Shares") to be acquired upon the exercise of stock options (the "Options") granted under the American International Group, Inc. 1999 Stock Option Plan (the "Plan"), when the registration statement relating to the Securities (the "Registration Statement") has become effective under the Act and Option Shares are duly issued and delivered upon the exercise of any of the Options in accordance with their terms and the terms of the Plan and are issued and sold as contemplated by the Registration Statement, the Option Shares will be validly issued, fully paid and non-assessable. The foregoing opinion is limited to the Federal laws of the United States and the laws of the State of Delaware, and I am expressing no opinion as to the effect of the laws of any other jurisdiction. I have relied as to certain matters on information obtained from public officials, officers of the Company and other sources believed by me to be responsible, and I have assumed that the certificates for the Securities will conform to the specimen of Common Stock examined by me and will be duly countersigned by a transfer agent and duly registered by a registrar of the Common Stock, that at the time of delivery of each Option Share all conditions to such delivery shall have been satisfied or waived, and that the signatures on all documents examined by me are genuine, assumptions which I have not independently verified. I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to me under the heading "Validity of Common Stock" in the Prospectus contained in the Registration Statement and under Item 5 "Interests of Named Experts and Counsel" of the Registration Statement". In giving such consent, I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the Act. Very truly yours, /S/ KATHLEEN E. SHANNON Kathleen E. Shannon Vice President and Associate General Counsel
