                LSI LOGIC TAKES STEPS TO REDUCE EXPENDITURES AND
                 ENHANCE COMPETITIVE POSITION FOR FUTURE GROWTH

MILPITAS, CALIFORNIA -- LSI Logic Corporation (NYSE:LSI) today reported 2001
first quarter revenues of $517 million, a 31 percent decrease from the $751
million reported in the fourth quarter, and 16 percent lower than the $615
million recorded in the first quarter of 2000.

First quarter 2001 net income, before amortization of goodwill and other special
items (EBG), was $9.5 million or 3 cents a diluted share, compared to $116
million or 34 cents a diluted share in the fourth quarter, and $88 million or 26
cents a diluted share in the first quarter of 2000.

"Our first quarter financial results were impacted by the abrupt decline of the
U.S. economy, weakened end-demand and the widespread accumulation of inventory
in the supply chain," said Wilfred J. Corrigan, LSI Logic chairman and chief
executive officer. "While our visibility is limited, there are indicators that
point to the resumption of revenue growth in the second half of the year.

"We announced an accretive transaction to acquire C-Cube Microsystems to expand
our position in global communications and consumer markets. We signed a process
technology collaboration agreement with TSMC, allowing us to more rapidly
deliver advanced products to the marketplace and to reduce our development
costs. We also announced the closure of our Colorado Springs facility,
consolidating our manufacturing to our world-class Gresham and Tsukuba fabs. LSI
Logic will compete from a position of strength when the industry rebounds with
leading-edge technology for the communications, storage and consumer markets."

Bryon Look, LSI Logic executive vice president and chief financial officer, said
the company will take a $120 million to $150 million charge for fixed asset
write-downs, severance, direct exit costs and other expenses associated with the
August closure of the company's Colorado Springs manufacturing facility. The
restructuring charge will be incurred in the second quarter, and other related
charges will be recorded in the second and third quarters of 2001.

"LSI Logic has responded aggressively to rapidly changing economic conditions,"
said Look. "We have taken action to reduce expenditures, invest in our future
and strengthen our balance sheet. We are prepared for the anticipated resumption
of growth in our targeted vertical markets."

LSI Logic also learned today that the Federal Trade Commission has granted early
termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act with respect to its exchange offer for all of the outstanding
shares of C-Cube common stock. In addition, LSI Logic anticipates that its
registration statement filed in connection with the exchange offer will be
declared effective by the Securities and Exchange Commission on April 26. The
exchange offer commenced on April 13, and is scheduled to expire at midnight EDT
on May 10, unless extended.

*       The amortization of acquisition related items including intangibles and
        non-cash deferred stock compensation for the quarter ended March 31,
        2001 are comprised of the following items:

**      On July 1, 2000, FASB Interpretation ("FIN") No. 44, " Accounting For
        Certain Transactions Involving Stock Compensation" was adopted by the
        Company. The acquisition of DataPath Systems, Inc. closed on July 14,
        2000 and Syntax Systems, Inc. closed on November 29, 2000, after the
        effective date of the new interpretation. In accordance with FIN No. 44,
        the intrinsic value of the options and restricted stock awards assumed
        as part of the transaction and not vested as of the closing date was
        recorded as deferred compensation and included as a component of
        stockholders' equity. The deferred compensation is being amortized over
        the respective vesting periods of the options and awards.

***     In computing diluted earnings per share for the three month period ended
        March 31, 2001, common stock equivalents were excluded from the
        computation of diluted earnings per share as a result of their
        antidilutive effect. In computing diluted earnings per share for the
        three month period ended March 31, 2000, net income was increased by
        $2,750 for interest, net of taxes, on the $345 million convertible notes
        considered dilutive common stock equivalents.
