Item 5. Other Events.

RenaissanceRe Holdings Ltd. ("RenaissanceRe") entered into an Investment
Agreement on September 20, 2002 with Platinum Underwriters Holdings, Ltd.
("Platinum") and The St. Paul Companies, Inc. ("St. Paul"). Pursuant to the
Investment Agreement, RenaissanceRe has agreed, subject to satisfaction of
certain conditions, to purchase 3,960,000 of the common shares of Platinum in a
private placement concurrent with the closing of Platinum's announced initial
public offering of its common shares and the closing of St. Paul's investment in
Platinum pursuant to a private placement. RenaissanceRe will purchase Platinum's
common shares at a price per share equal to the initial public offering price,
less the underwriting discount.

The purchase will amount to 9.9% of Platinum's common shares outstanding
following closing, assuming the underwriters' over-allotment option is not
exercised. RenaissanceRe's investment in Platinum is expected to be in the range
of $82 to $100 million. In connection with its investment, RenaissanceRe will
also receive a ten-year option to purchase up to 2,500,000 common shares of
Platinum at a per share price equal to 120% of the initial public offering
price.
