Adaptec Acquires Power I/O Corporation



Milpitas, Calif, - November 7, 1995 - Adaptec Inc.(NASDAQ:ADPT), announced

today that it has acquired Power I/O Corporation of Irvine, California in a

$7 million cash transaction. Power I/O, a privately-held company founded in

1993, develops high-speed input/output (I/O) and networking technologies.



Grant Saviers, Adaptec chief executive officer, described the acquisition

as "A synergistic move for our company. As client-server computing becomes

more involved in mission-critical applications, we at Adaptec are

developing serial interface technologies that ensure the evolution will be

a successful one. Power I/O's expertise in enabling 1 gigabit-per-second

fibre channel technology, based on Hewlett-Packard’s Tachyon technology,

complements and will accelerate our own efforts."



The acquisition of Power I/O will be accounted for under the purchase

accounting method. Adaptec is in the process of evaluating the allocation

of the purchase price to the assets acquired, which include in-process

technology that will be written off in the third quarter of FY96, and

goodwill, which will be amortized over the benefit period. The facilities

of Power I/O will be consolidated with other Adaptec operations located in

Irvine.
