                     LSI LOGIC COMPLETES C-CUBE ACQUISITION

   Strategic Acquisition Combines Product Lines, Sales Channels and Technology
     Development Strengths of Two Consumer and Communications Market Leaders

MILPITAS, CA - LSI Logic Corporation (NYSE: LSI) today announced it has
completed its $851 million acquisition of C-Cube Microsystems Inc. (Nasdaq:
CUBE) by means of an exchange offer and subsequent merger of a wholly owned
subsidiary of LSI Logic into C-Cube. As a result of this acquisition, C-Cube
became a wholly owned subsidiary of LSI Logic.

In the exchange offer, LSI Logic acquired more than 90 percent of the shares of
C-Cube common stock, including shares tendered during the subsequent offering
period, which expired June 8. In the merger, each remaining share of C-Cube
common stock was converted into the right to receive 0.79 of a share of LSI
Logic common stock, the same consideration offered for shares of C-Cube common
stock tendered in the exchange offer and the subsequent offering period.

"This strategic acquisition brings the combined strengths of two technology
leaders to the global consumer electronics marketplace," said Wilfred J.
Corrigan, LSI Logic chairman and chief executive officer. "LSI Logic will now
compete in worldwide cable modem, cable set-top box, DVD and other major
markets. In turn, C-Cube will have access to LSI Logic technologies, engineering
talent and global sales channels. The net effect of this transaction is an
enhanced competitive position for LSI Logic in rapidly converging consumer and
communications markets."

"We are excited about the opportunity to combine our complementary engineering
skill sets and consumer-market position into LSI Logic," said Umesh Padval,

and former C-Cube president and chief executive officer. "Our combined strengths
will enable us to provide a complete array of technologies for high-growth
cable, satellite, terrestrial and DSL set-top boxes, DVD as well as new,
emerging markets such as home media servers and residential gateways. All of the
critical technologies are now in place to capitalize on the rapidly growing
market for the networked digital home."

LSI Logic's consumer and communications market offerings include: satellite
digital set-top boxes, terrestrial digital set-top boxes and DSL. C-Cube is a
leading provider of silicon-based solutions for digital set-top box, DVD and
