(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. 2 "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, recently appointed LSI Logic senior vice president of Broadband Entertainment 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."
