San Jose, Calif., and Nepean, Ontario, January 17, 2000 - JDS Uniphase Corporation (NASDAQ: JDSU; TSE: JDU) and E-TEK Dynamics Inc. (NASDAQ: ETEK) announced today the signing of a definitive merger agreement valued at approximately $15 billion based on January 14, 2000 closing stock prices.

The merger agreement provides for the exchange of 1.1 shares of JDS Uniphase common stock for each common share of E-TEK. Completion of the transaction is subject to customary closing conditions, including an E-TEK stockholders' vote and regulatory approvals. Following completion of the transaction, E-TEK will operate as a wholly-owned subsidiary of JDS Uniphase.

The companies are proposing to merge in response to unprecedented growth in the telecommunications industry today. As a result of the explosive demand for bandwidth, service providers have accelerated deployment of fiberoptic systems in their networks. To meet these aggressive deployment plans, systems manufacturers are looking both internally and to merchant optical component and module suppliers to expand production, shorten development cycles and provide new products and functionalities.

The merger brings together the complementary strengths of JDS Uniphase and E-TEK Dynamics and is expected to enable a more rapid scaling of operations bringing greater volume and a broader range of products to customers faster. One of the many expected benefits of the merger will be the combination of E-TEK's packaging technology and capacity with JDS Uniphase's optical filter capability and supply which was enhanced by its pending merger with OCLI.

In addition to the merger, the companies also announced the signing of a mutual supply agreement in order to immediately increase the supply of certain of the companies' products to customers.

Kevin Kalkhoven, JDS Uniphase Co-Chairman and CEO stated, "We are very pleased to be joining E-TEK with JDS Uniphase. As a combined entity, we expect to have deeper resources to continue our strategy of expanding our scale and scope to enable the industry to fulfill the optical promise of unlimited bandwidth."

Michael Fitzpatrick, E-TEK Chairman, President and CEO added, "We are very excited about the merger of our two companies. By joining together, we believe we will eliminate inefficiencies in the supply chain, allowing us to deliver more products to our customers. In doing so, we hope to catalyze the evolution of optical networking."

Jozef Straus, JDS Uniphase, Co-Chairman, President and COO commented, "Today's announcement marks the beginning of a great partnership between two companies with a common passion for optical networking. We strongly believe that our combined manufacturing capacity and product innovation capability will strengthen our ability to meet and exceed our customer expectations."

E-TEK has approximately 2,450 employees and reported revenues of $72.5 million in its second quarter ended January 1, 2000. JDS Uniphase has over 8,200 employees and reported sales of $230.1 million in its first quarter ended September 30, 1999.
