[JDS UNIPHASE LOGO]                                                   [SDL LOGO]

                JDS UNIPHASE AND SDL AGREE TO $41 BILLION MERGER

NEPEAN, ONTARIO AND SAN JOSE, CALIFORNIA, JULY 10, 2000 -- JDS Uniphase
Corporation (NASDAQ: JDSU; TSE: JDU) and SDL, Inc. (NASDAQ: SDLI) announced
today their definitive agreement to merge in a transaction valued at
approximately $41 billion based on July 7, 2000 closing stock prices.

        The merger agreement provides for the exchange of 3.8 shares of JDS
Uniphase common stock for each common share of SDL. Completion of the
transaction is subject to customary closing conditions, including the approval
of stockholders' of both companies and regulatory approvals. Following
completion of the transaction, SDL will operate as a wholly-owned subsidiary of
JDS Uniphase.

        The growth of the Internet has created rapidly accelerating demand for
bandwidth that is driving the build-out of significantly increased
telecommunication network capacity and flexibility. Telecommunications system
providers are developing those network systems based upon optical technologies
that require advanced components and modules with increasing levels of
integration and complexity.

        The merger of JDS Uniphase and SDL is expected to facilitate the
creation and deployment of high-capacity, flexible optical networks by
accelerating the delivery of advanced products and basic building blocks of
optical networks. These include optical amplifiers, lossless optical switches,
integrated optical modules and other innovative solutions. The strong technology
platforms from both companies encompass high-speed electronics, different forms
of modulation, advanced multiplexing, enhanced active technologies, and a broad
passive portfolio intended to make these products a reality.

        Jozef Straus, JDS Uniphase Co-Chairman and CEO commented, "I am thrilled
and excited about this merger and to have the opportunity to work closely
together with Don Scifres and his team. JDS Uniphase and SDL share a common
vision to provide customers with the most innovative and technologically
advanced products that enhance their ability to deliver next-generation optical
systems."

        Don Scifres, SDL Chairman, President and CEO added, "This combination
brings together world class technical and manufacturing teams that promise to
deliver best-in-class products at increased volumes for today's systems while
developing solutions for tomorrow. We also expect to enable the migration from
today's hybrid integration and module level products to tomorrow's truly
integrated system on a chip."
