Business Editors

NEW YORK & HOUSTON--(BUSINESS WIRE)--May 11, 2001

American International Group, Inc. (NYSE: AIG) and American General Corporation (NYSE: AGC) today announced that they have entered into a definitive agreement under which American General shareholders will receive $46 per American General share in AIG common stock, subject to a collar mechanism. The transaction, which has been approved by the boards of directors of both companies, will be a tax-free reorganization and will be treated as a "pooling of interests" for accounting purposes. The transaction values American General at approximately $23 billion.

Simultaneous with entering into this definitive agreement, American General terminated its previous merger agreement with Prudential plc, and paid Prudential the $600 million termination fee specified in that agreement.

Commenting on the announcement, AIG Chairman and CEO, M.R. Greenberg said, "We are very pleased to have reached this agreement with American General, whose leading positions in life insurance, retirement savings products, and consumer finance will enhance AIG's business portfolio, both in terms of products and distribution. The acquisition of American General will significantly strengthen our position in the domestic life insurance market. In addition, American General's annuity businesses will complement AIG's existing retirement savings business, giving us an even stronger platform from which to capitalize on the significant growth we see in retirement savings in the years ahead. We also look forward to deploying American General's expertise in U.S. consumer finance to accelerate AIG's expanding global consumer finance business. As part of this acquisition, we are also very pleased we could reach an amicable solution with Prudential."

"We are excited about joining AIG, the world's leader in insurance and financial services," said Robert M. Devlin, American General Chairman and CEO. "This transaction represents an outstanding strategic fit for both companies. It will create superior value for our shareholders, expanded financial solutions for our customers and significant opportunities for employees and distribution partners. American General's strong franchise positions in life insurance, annuities, and consumer lending will become a significant contributor to AIG's domestic operations and will enhance the company's global capabilities. On behalf of American General's board of directors and our management team, I would like to thank the men and women of American General for their outstanding contributions to this pivotal moment in our 75-year history."

American General shareholders will receive AIG common stock according to an exchange ratio that will be determined based on the 10-day average price of AIG's common stock ending three days prior to closing. This exchange ratio will provide American General shareholders AIG common stock valued at $46 per American General share as long as AIG's average price is between $76.20 and $84.22 during this pricing period. In the event that AIG's price is equal to or less than $76.20 or equal to or more than $84.22, American General shareholders will receive 0.6037 or 0.5462 AIG shares, respectively.

The transaction should be immediately accretive to AIG's earnings per share. The transaction is subject to various regulatory approvals and other customary conditions, as well as the approval of American General shareholders, and is expected to close by year end.
