Business Editors, Legal Writers

WASHINGTON--(BUSINESS WIRE)--Nov. 8, 2002

Cohen Milstein Hausfeld & Toll, P.L.L.C. has filed a securities fraud class action suit with an expanded class period in the United States District Court for the District of Massachusetts against Credit Suisse First Boston Corporation, a subsidiary of Credit Suisse Group (NYSE:CSR), ("Credit Suisse" or the "Company"), and one of its technology analysts.

The case was filed on behalf of all persons who purchased common stock of AOL Time Warner Inc. (NYSE:AOL) ("AOL") during the period from Jan. 12, 2001 through Sept. 3, 2002 (the "Class Period").

The complaint alleges that the defendants violated section 10(b) of the Securities Exchange Act of 1934 ("the Exchange Act"), and Rule 10b-5 promulgated thereunder, and Section 20(a) of the Exchange Act, by issuing a series of favorable research reports on AOL that were materially false or misleading in that they did not reflect Credit Suisse's true opinion of AOL and they did not disclose conflicts of interest of Credit Suisse. In particular, the reports did not disclose the practice of Credit Suisse to use its research coverage as part of its marketing efforts to gain lucrative investment banking business.

According to an administrative complaint filed by the Secretary of the Commonwealth of Massachusetts, on one occasion Credit Suisse issued an analyst report stating Credit Suisse believed AOL could achieve the earnings guidance AOL had given the market, when Credit Suisse in fact believed (as expressed in internal communications) that AOL could not make its numbers. The Massachusetts complaint alleges that Credit Suisse "purposely misled investors" with its analyst reports.

Cohen, Milstein, Hausfeld & Toll, P.L.L.C. has previously filed class action securities fraud suits against Credit Suisse on behalf of purchasers of Razorfish, Inc. and Agilent Technologies, Inc. common stock.
