FINISAR CORPORATION ANNOUNCES AGREEMENT TO ACQUIRE SHOMITI SYSTEMS, INC.

SUNNYVALE, Calif.--(BUSINESS WIRE)--Nov. 21, 2000--Finisar Corporation (Nasdaq:
FNSR), a leading provider of gigabit fiber optic solutions for high-speed data
networks, today announced it has entered into a definitive agreement to acquire
Shomiti Systems, Inc. Shomiti Systems, headquartered in San Jose, California,
has developed a broad line of Ethernet and voice over internet protocol (VoIP)
analysis products from 10 megabits to 10 gigabits.

Live Webcast

Additional information about Finisar's pending acquisition of Shomiti Systems
will be available in a webcast at www.finisar.com scheduled for today, November
21, at 5:00 pm EDT (2:00 pm PDT). A replay of this webcast will be available
beginning approximately eight hours later.

Background

Established in 1995, Shomiti Systems is a technology leader in designing
products which measure the performance of Ethernet networks in order to enhance
their quality of service (QoS). Shomiti's award-winning "Surveyor" and
"Explorer" line of products are currently being deployed for measuring and
monitoring 10-100 megabit and Gigabit Ethernet local area networks (LANs) and
e-commerce storage server farms. With the acquisition of Shomiti Systems,
Finisar will gain access to this fundamental technology in its quest to extend
its capabilities as a provider of next generation test equipment for Fibre
Channel, Gigabit Ethernet and Infiniband networks.

"We have always felt that our strength in designing optical subsystems for Fibre
Channel applications was amplified by the ability to design instruments which
are able to test, monitor and troubleshoot these optical devices in a storage
area network (SAN)," said Jerry Rawls, Finisar's President and CEO. "With the
addition of Shomiti, we have created a similar capability for Ethernet and IP
networking applications," added Rawls.

"With Finisar's reputation in Fibre Channel test instruments and their growing
presence in Gigabit Ethernet, we are a perfect fit for them," said Bill Shaw,
Shomiti's President and CEO. "Our combined company will span all of the
technologies that underlay local area network (LAN) and storage area network
(SAN) applications including SCSI storage over IP, Fibre Channel or Infiniband
and IP and VoIP analysis on Ethernet or Infiniband. Our combined strengths in
ASIC design and software development will make Finisar a formidable opponent in
providing state-of-the-art tools for network analysis," added Shaw.

Transaction

Under the terms of the agreement, Shomiti Systems will merge with a wholly-owned
subsidiary of Finisar, and Shomiti stockholders will be entitled to receive up
to approximately 4.3 million shares of Finisar Common Stock including shares
issuable upon exercise of options assumed in the merger. The transaction will be
accounted for as a purchase and is intended to qualify as a tax-free
reorganization. The closing price of Finisar's Common Stock on November 20, 2000
was $22.13 per share, giving the transaction an approximate value of $95
million. The transaction is expected to close during the first calendar quarter
of 2001 and is subject to approval by Shomiti's stockholders, the notification
requirements of the Hart-Scott-Rodino Antitrust Act and other customary
conditions.

Following the merger, Shomiti Systems will operate as a subsidiary of Finisar at
its current facility in San Jose, California. Bill Shaw, Shomiti's President and
CEO, will continue to serve as President and CEO of the Shomiti subsidiary.
