                REQUIRED DISCLOSURE FOR NORTH CAROLINA RESIDENTS
 
     The Commissioner of Insurance of the State of North Carolina has not
approved or disapproved this offering nor has the Commissioner passed upon the
accuracy or adequacy of this Prospectus.
 
                                   THE PLANS
 
     The following is a brief summary of the Plans which does not purport to be
complete. The Plans are all substantially identical.
 
     Key employees of SICO, AIG and their affiliates participate in the Plans.
Neither AIG nor SICO has received or will receive any cash or property in
consideration of the granting of units under the Plans.
 
     Under the Plans, Participants are granted units which have a value based on
a percentage (selected by SICO's Board of Directors) of SICO's retained earnings
attributable to the shares of Common Stock held by SICO over a two year period.
The units are payable, at the election of SICO's Board of Directors, in cash or
Common Stock. The units generally vest upon retirement at normal retirement age,
except the SICO Board of Directors has, with respect to certain of the Plans,
permitted an early pay-out of units under certain circumstances.
 
                              SELLING SHAREHOLDERS
 
     The Selling Shareholders will consist of Participants who may be deemed to
be "affiliates" of AIG for purposes of 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 Plan
Shares which such Selling Shareholder intends to sell pursuant to this
Prospectus.
 
     The directors and officers of AIG as a group own 81.82% of the voting stock
of SICO; SICO owns 16.14% of the outstanding Common Stock and, after giving
effect to the delivery of the 5,000,000 Plan Shares covered by this Prospectus,
will own 15.07% of the outstanding Common Stock. Six directors of AIG also serve
as directors of SICO, and SICO provides certain compensation to directors and
executive officers of AIG. In the ordinary course of business, AIG and its
subsidiaries effect certain transactions with SICO at a cost which, in the
opinion of AIG's management, is not material and does not exceed the cost of
obtaining such services from unaffiliated sources. For a further discussion of
AIG's relationship to SICO, see AIG's Annual Report on Form 10-K for the year
ended December 31, 1995, incorporated herein by reference.
 
                              PLAN OF DISTRIBUTION
 
     Plan Shares may be sold from time to time by the Selling Shareholders, or
by their 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. Plan Shares may be
sold by the Selling Shareholders by one or more of the following: (a) a block
trade in which the broker-dealer so engaged will attempt to sell such Plan
Shares as agent but may position and resell a portion of the block as principal
to facilitate the transaction; (b) purchase of such Plan Shares by a
broker-dealer as principal and resale by such broker-dealer for its account
pursuant to this Prospectus; and (c) 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
 
                                        4
<PAGE>   7
 
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.
 
     All costs, expenses and fees in connection with the registration of the
Plan Shares, including any sold by the Selling Shareholders, will be borne by
SICO. Commissions and discounts, if any, attributable to the sales of Plan
Shares by the Selling Shareholders will be borne by the Selling Shareholders.
 
                            VALIDITY OF COMMON STOCK
 
     The validity of the Plan Shares 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.
 
                                    EXPERTS
 
     The consolidated financial statements and schedules of AIG as of December
31, 1995 and 1994 and for each of the three years in the period ended December
31, 1995, included in AIG's Annual Report on Form 10-K for the year ended
December 31, 1995, have been audited by Coopers & Lybrand L.L.P., independent
public accountants, as indicated in their reports with respect thereto, dated
February 22, 1996, and are incorporated by reference into this Prospectus in
reliance thereon upon the authority of said firm as experts in accounting and
auditing.

(1) 27,148 Shares are held in escrow with Chase Manhattan Bank, as escrow agent,
    and 10,860 Shares are subject to an Employment Agreement, dated August 12,
    1996, between AIG and Mr. Meyers which contains customary forfeiture
    provisions.
(2) Each of Ms. Miller's, Ms. Rachelson's and Mr. Schiller's Shares are held in
    a trust for their respective benefit, and are subject to customary
    forfeiture provisions. Chase Manhattan Bank acts as trustee for each of such
    trusts.
 
                              PLAN OF DISTRIBUTION
 
     The Shares may be sold from time to time by the Selling Shareholders, or by
their 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
by one or more of the following: (a) 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; (b) purchase of
such Shares by a broker-dealer as principal and resale by such broker-dealer for
its account pursuant to this Prospectus; and (c) 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.
 
     All costs, expenses and fees in connection with the registration of the
Shares will be borne by AIG. Commissions and discounts, if any, attributable to
the sales of the Shares will be borne by the Selling Shareholders.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Restated Certificate of Incorporation of the Company (the
"Certificate") provides that the Company 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 the Company. Section 6.4 of the Company's By-laws
contains a similar provision.
 
     The Certificate also provides that a director will not be personally liable
to the Company 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
Company 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
the Company. Section 145 also provides that the indemnification provided for
therein shall not be deemed exclusive of any other rights to which those seeking
indemnification may otherwise be entitled. In addition, the Company and its
subsidiaries maintain a directors' and officers' liability insurance policy.

ITEM 17. CERTAIN UNDERTAKINGS.
 
     (a) 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 of 1933, (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
 
                                      II-2
<PAGE>   27
 
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in this 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
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 this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that subparagraphs (i) and (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 Commission by the Registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934, as amended, 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 securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof; and
(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.
 
     (b) The Registrant undertakes that, for the purpose 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 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
of 1933 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 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.

                       AMERICAN INTERNATIONAL GROUP, INC.
                             STOCK OPTION AGREEMENT

         Agreement, dated September 16, 1996 between American International
Group, Inc. ("AIG") and Pei-yuan Chia (the "Director"), a director of AIG.

         The parties hereto agree as follows:

         1. Grant of Option. AIG hereby grants to the Director an option to
purchase all or any part of 5,000 shares of AIG Common Stock (the "Common
Stock") at a price of $98.75 per share at any time after one year from the date
hereof or at such earlier time as provided in Section 4 of this Agreement. Such
option shall expire on September 16, 2006 or at such earlier time as provided in
Section 4 of this Agreement.

         2. Exercisability of Option. This option is not transferable by the
Director otherwise than by will or the laws of descent and distribution, and is
exercisable during the lifetime of the Director only by the Director. In the
event of the death of the Director, the option may be exercised by the person or
persons to whom the Director's rights under the option are transferred by will
or the laws of descent and distribution.

         3. Exercise of Stock Option and Payment for Shares. To exercise the
stock option, the Director shall give written notice to AIG specifying the
number of shares to be purchased and accompanied by payment of the full purchase
price therefor. Upon the exercise, the Director shall make such representations
and agreements and furnish such information as AIG may deem necessary or
desirable to assure compliance by AIG, on terms acceptable to AIG, with the
provisions of the Securities Act of 1933 and any other applicable legal
requirements. If the Director so requests, shares purchased may be issued in the
name of the Director and another jointly with the right of survivorship.

         4. Termination of Directorship. Upon termination of the Director's
service as a director of AIG, the option shall be exercisable as follows:

                  (i)      if such termination of directorship is due to
                           disability, any portion of the option, whether or not
                           exercisable at the time of such termination, may be
                           exercised by the Director or his legal representative
                           at any time on or before September 16, 2006;

                  (ii)     if such termination of directorship is due to death,
                           any portion of the option, whether or not exercisable
                           at the time of such termination, may be exercised by
                           the legal representative of the Director at any time
                           within five years after the death of the Director
                           (but in no event later than September 16, 2006); and

                  (iii)    if such termination of directorship is not due to
                           disability or death, any portion of the option may be
                           exercised by the Director within five years after
                           such termination (but in no event after September 16,
                           2006), but only to the extent such option was
                           exercisable at the time of such termination.

         5. Adjustments in Event of Changes in Capitalization. In the event of a
recapitalization, stock split, stock dividend, combination or exchange of
shares, merger, consolidation, rights offering, separation, reorganization or
liquidation, or any other change in the corporate structure or shares of AIG
subsequent to the date hereof, the Board of Directors shall make such equitable
adjustments, designed to protect against dilution or enlargement of rights, as
it may deem appropriate in the number and kind of shares covered hereby and in
the option price.

               [AMERICAN INTERNATIONAL GROUP, INC. LETTERHEAD]

                                                            

                                                            February 7, 1997



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
(the "Act") of 5,152,684 shares (the "Securities") of Common Stock, par value
$2.50 per share, 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 questions 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:

                (1) With respect to the Securities (the "Plan Shares") to be
        delivered by Starr International Company, Inc. ("SICO") pursuant to 
        SICO's Deferred Compensation Profit Participation Plans, as amended 
        (collectively, the "Plans"), the Plan Shares have been duly
        authorized and validly issued and are fully paid and non-assessable.

                (2) With respect to the Securities (the "Option Shares") to be
        acquired upon the exercise of stock options granted under (i) the Stock
        Option Agreement, dated February 9, 1995 (the "Bentsen Option"),
        between the Company and Lloyd M. Bentsen, (ii) the Stock Option
        Agreements, each dated February 21, 1995 (the "1995 Options"), between
        the Company and each of M. Bernard Aidinoff, Marshall A. Cohen, Barber
        B. Conable, Jr., Martin S. Feldstein, Carla A. Hills, Frank J.
        Hoenemeyer, John I. Howell and Dean P. Phypers (collectively, the "1995
        Optionees"), (iii) the Stock Option Agreement, dated September 16, 1996
        (the "Chia Option"), between the Company and Pei-yuan Chia and (iv) the
        Stock Option Agreements, each dated December 31, 1996 (the "1996
        Options" and, together with the Bentsen Option, the 1995 Options and
        the Chia Option, the "Options"), between the Company and each of the
        1995 Optionees (other than Mr. Howell), when the registration 
        statement relating to the Securities (the "Registration Statement") has
        become effective under the Act and Option Shares are delivered upon the
        exercise of any of the Options in accordance with their terms as
        contemplated by the Registration Statement, the Option Shares will be
        validly issued, fully paid and non-assessable.

                (3) With respect to the Securities (the "Selling Shareholder
        Shares") to be offered from time to time in one or more transactions
        by Stuart A. Myers, Sari Miller, Eileen Rachelson and non-employees and 
        Fred Schiller, the Selling Shareholder Shares have been duly authorized
        and are, or when issued will be, validly issued, fully paid and 
        non-assessable.

                (4) With respect to the Securities (the "Prize Shares") to be
        delivered from time to time by the Company to employees and
        non-employees as gifts, prizes and in other similar transactions, when
        the Registration Statement has become effective under the Act and the
        Prize Shares have been delivered as contemplated by the Registration
        Statement, the Prize 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 General Corporation Law 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.

        I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to me under the headings "Validity
of Common Stock" in each of the Prospectuses contained in 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
