   2

        This final Amendment to the Tender Offer Statement on Schedule TO (this
"Schedule TO") relates to the expiration of a subsequent offering period (the
"Subsequent Offering Period") in connection with an offer by LSI Logic
Corporation, a Delaware corporation ("LSI Logic"), through its wholly owned
subsidiary, Clover Acquisition Corp., a Delaware corporation ("Purchaser"), to
exchange outstanding shares of common stock, par value $0.001 per share (C-Cube
Common Stock), of C-Cube Microsystems Inc., a Delaware corporation ("C-Cube"),
for shares of common stock, par value $0.01 per share, of LSI Logic ("LSI Logic
Common Stock"), based on the exchange ratio described in the Prospectus
referenced below (the "Offer"), and the subsequent merger of Purchaser into
C-Cube (the "Merger").

        The Offer was made pursuant to an Agreement and Plan of Reorganization,
dated as of March 26, 2001, among LSI Logic, Purchaser and C-Cube (the
"Reorganization Agreement"), which contemplates the Offer and the Merger. LSI
Logic has filed a registration statement with the Securities and Exchange
Commission on Form S-4, as amended (No. 333-58862), relating to the shares of
LSI Logic Common Stock to be issued to stockholders of C-Cube in the Offer and
the Merger (the "Registration Statement"). The terms and conditions of the Offer
and the Merger are described in the Prospectus which is a part of the
Registration Statement (the "Prospectus"), and the related Letter of
Transmittal, which have been filed as Exhibits (a)(1) and (a)(2) to the Schedule
TO filed by LSI Logic with the Securities and Exchange Commission on April 13,
2001. The initial expiration date of the Offer occurred at midnight, New York
time, on Thursday, May 10, 2001. After the initial expiration date of the Offer,
LSI Logic commenced the Subsequent Offering Period which began at 9 a.m., New
York time, on Friday, May 11, 2001, and expired at midnight, New York time, on
Friday, June 8, 2001.

        All of the information in the Prospectus and the related Letter of
Transmittal, and any prospectus supplement or other amendment thereto related to
the Offer hereafter filed with the Securities and Exchange Commission by LSI
Logic and Purchaser, is hereby incorporated by reference in answer to Items 2
through 11 of this Schedule TO.
