                      PRUDENTIAL FILES LAWSUIT AGAINST AIG



LONDON, UK - Prudential plc announced today that it has begun an action against
American International Group, Inc. (AIG) for tortious interference with the
pending merger between Prudential and American General Corporation. The suit,
which has been brought in Texas State District Court in Harris County, alleges
that AIG has tortiously interfered with the prospective merger and the existing
merger contract between Prudential and American General. While AIG may have had
the right to make an offer, it does not have the right to interfere with the
merger using illegal or improper means. The Petition alleges that it has done
both.

Prudential alleges that AIG has engaged in illegal "gun jumping" in publicly
offering its shares in violation of Section 5 of the Securities Act of 1933
which prohibits offers of securities without the prior filing of a registration
statement or full compliance with certain conditions. By not filing its press
release and a transcript of its analysts' call as prospectuses, AIG may also
escape liability for any false or misleading statements under the statutory
provisions applicable to prospectuses.

The Petition also alleges that AIG has made false and misleading statements in
characterising its own proposal by not adequately explaining the conditionality
of that proposal or its value. Further, AIG's description of the conversations
that its chief executive had with American General's chief executive, if true,
would be in knowing violation of the merger contract and thus constitute
tortious interference with contract and, if false, would be further misleading
statements constituting tortious interference with prospective business
relations, according to the Petition.

The Petition seeks a temporary restraining order and a temporary and permanent
injunction against AIG continuing to violate Section 5 of the Securities Act and
from continuing to interfere with the merger contract. It also seeks actual and
exemplary damages against AIG.

Prudential plc noted that when applicable rules governing takeover bids in the
United Kingdom are violated, the injured party has a remedy through the Takeover
Panel. There is no equivalent agency in the United States under these
circumstances and the only means to protect its rights is through the judicial
system.
