Explanation of Responses:

1. This transaction represents a gift of shares of AIG common stock previously owned by Mr. and Mrs. Greenberg as tenants in common to a family trust for which Mr. Greenberg is the trustee.

2. On May 18, 2006, Mr. and Mrs. Greenberg contributed 500,000 shares of AIG common stock they owned as tenants in common to an exchange fund over which they have no control in exchange for shares of the exchange fund. The AIG common stock was valued at $62.50 per share for purposes of determining the number of shares of the exchange fund issuable. Mr. Greenberg disclaims the beneficial ownership of, and any pecuniary interest in, the shares of AIG common stock contributed to the exchange fund.

3. Shares of common stock of AIG are owned by family trusts for which Mr. Greenberg is the trustee. Mr. Greenberg may be deemed to be the beneficial owner of, and to have a pecuniary interest in, the shares of AIG common stock owned by the family trusts. Mr. Greenberg disclaims the beneficial ownership of, and any pecuniary interest in, the shares of AIG common stock owned by the family trusts. Previous reports of beneficial ownership immaterially misstated the number of shares of AIG stock owned by family trusts for which Mr. Greenberg is the trustee.

4. Mr. Greenberg owns 24.082% of the total outstanding shares of common stock of C. V. Starr & Co., Inc. ("CV Starr"). As of the close of business on May 19, 2006, CV Starr beneficially owned 22,632,968 shares of American International Group, Inc. ("AIG") common stock, excluding 18,644,278 shares of AIG common stock that are owned by C. V. Starr & Co., Inc. Trust (the "CV Starr Trust"), for which CV Starr is a beneficiary and Mr. Greenberg is a trustee.

5. As a result of the factors discussed in footnote 4 above, Mr. Greenberg may be deemed to have a pecuniary interest in the shares of AIG common stock beneficially owned by CV Starr. Mr. Greenberg believes that any pecuniary interest that he may be deemed to have in shares of AIG common stock beneficially owned by CV Starr would not exceed the percentage of his common stock ownership of CV Starr. Accordingly, Mr. Greenberg has reported only the effect on his proportionate interest in CV Starr of transactions by CV Starr in its common stock. Mr. Greenberg disclaims the beneficial ownership of, and any pecuniary interest in, the shares of AIG common stock owned by CV Starr.

6. Mr. Greenberg may be deemed to be the beneficial owner of, and to have a pecuniary interest in, the shares of AIG common stock owned by the CV Starr Trust. Mr. Greenberg disclaims the beneficial ownership of, and any pecuniary interest in, the shares of AIG common stock owned by the CV Starr Trust.

7. 381,507 shares of common stock of AIG are owned by The Maurice R. and Corinne P. Greenberg Family Foundation, Inc. (the "Greenberg Foundation"), of which Mr. Greenberg is chairman of the board of directors. Mr. Greenberg may be deemed to be the beneficial owner of, and to have a pecuniary interest in, the shares of AIG common stock owned by the Greenberg Foundation. Mr. Greenberg disclaims the beneficial ownership of, and any pecuniary interest in, the shares of AIG common stock owned by the Greenberg Foundation.

Remarks:

Mr. Greenberg may be deemed to beneficially own more than 10% of the common stock of American International Group, Inc. under Rule 16a-1(a)(1) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as a result of him being deemed a member of a group under Section 13(d)(3) of the Exchange Act.
