                QLOGIC CORPORATION ANNOUNCES 2-FOR-1 STOCK SPLIT

         Costa Mesa, Calif., January 19, 2000 -- QLogic Corporation
(Nasdaq:QLGC), a leading designer and supplier of semiconductor and board-level,
input/output (I/O) and enclosure management products, announced today that its
Board of Directors approved a two-for-one stock split of the Company's issued
and outstanding common stock to be effected by way of a stock dividend. On the
ex-dividend date of February 9, 2000, stockholders will be entitled to receive
one additional share for every share they own on the record date of February 2,
2000. Following the effective date of the split, QLogic will have approximately
73 million shares outstanding. This action will be the third time that QLogic's
stock has been split since the Company's stock commenced public trading.
Previous two-for-one stock splits occurred in February 1999 and August 1999.

         QLogic Corporation is a leading designer and supplier of semiconductor
and board-level I/O (input/output) and enclosure management products. The
Company's products provide high-performance interface connections between
computer systems and their attached data storage peripherals, such as hard disk
drives, tape drives and RAID subsystems. In addition, QLogic provides enclosure
management products that monitor and communicate management information related
to components that are critical to computer system and storage subsystem
reliability and availability. QLogic's highly integrated, fully featured
solutions are targeted at the computer system, storage device and storage
subsystem marketplaces. The Company believes

   2

that its I/O and enclosure management solutions encompass one of the industry's
broadest ranges of Fibre Channel and SCSI technologies, and offer OEM customers
a simple, low risk migration path between technologies.

         With the exception of historical information, the statements set forth
above include forward-looking statements that involve risks and uncertainties.
The Company wishes to advise readers that a number of important factors could
cause actual results to differ materially from those in the forward-looking
statements. Those factors include uncertainties concerning the identification
and integration of appropriate technology acquisitions and new technical
personnel; new and changing technologies and uncertain customer acceptance of
those technologies; a change in semiconductor foundry capacity or conditions;
fluctuations in the growth of I/O markets; fluctuations or cancellations in
orders from OEM customers; the Company's ability to compete effectively with
other companies; cancellation of OEM products associated with design wins; and
reductions in the need for space and increased costs of operations due to
facility relocation. Carrying additional expansion space may increase costs and
adversely impact future earnings. These and other factors which could cause
actual results to differ materially are also discussed in the company's filings
with the Securities and Exchange Commission, including its recent filings on
Form S-3, Form 10-K, and Form 10-Q. Trademarks and registered trademarks are the
property of the companies with which they are associated.

         More information on QLogic is available from the Company's SEC filings.
