Company Press Release

QLogic Corporation Acquires AdaptiveRAID Technology for New I/O Interfaces COSTA
MESA, Calif.--(BUSINESS WIRE)--Jan. 10, 2000--QLogic Corporation (Nasdaq: QLGC -
news), the market share leader in Fibre Channel host bus adapters, and an
innovator in SCSI connectivity solutions, today announced that it has acquired
certain intellectual property from Borg Adaptive Technologies, Inc., a
wholly-owned subsidiary of nStor Corporation. The technology, known as
AdaptiveRAID(R), was purchased for $7.5 million in cash. As part of the
transaction, QLogic will assume a facility lease in Boulder, Colorado where it
plans to open a design center.

"By adding the AdaptiveRAID(R) technology and the associated engineers to
QLogic's resource pool, the Company is preparing for the development of new I/O
interfaces, such as InfiniBand(SM)," according to H.K. Desai, the Company's
Chairman, President and CEO. "We expect deployment of InfiniBand(SM)-based
technologies to occur in the next several years. These new interfaces will
require enhanced software and hardware I/O capabilities," added Mr. Desai.

Mr. Desai also noted QLogic is highly enthusiastic about establishing a design
center in Boulder, as this will give the Company access to local software,
firmware and ASIC engineering resources. The new Boulder location should
complement QLogic's current engineering activities in Orange County and Austin,
according to Mr. Desai.

The Company will account for this transaction in its fourth fiscal quarter
ending April 2, 2000. The Company will evaluate the allocation of the purchase
price to the assets acquired. Such assets include in-process technology that
will be written off in the fiscal quarter ending April 2, 2000, and goodwill
associated with AdaptiveRAID(R) technology which will be amortized over its
useful life. The impact of the in-process technology write-off is expected to be
material to the Company's fiscal fourth quarter earnings. Excluding the
in-process technology write-off, the impact of the purchase to earnings in
fiscal 2000 is expected to be immaterial.
