Nepean, Ontario and San Jose, Calif., June 22, 2000 - JDS Uniphase Corporation (Nasdaq: JDSU and TSE: JDU) and E-TEK Dynamics, Inc. (Nasdaq: ETEK) announced today that they have reached an agreement with the United States Department of Justice ("DOJ") that will permit JDS Uniphase to complete its merger with E-TEK. The consent decree with the DOJ gives antitrust clearance to the merger, which is now subject only to E-TEK stockholder approval and the other customary closing conditions specified in the merger agreement. A special meeting of E-TEK's stockholders has been set for June 28, 2000. If E-TEK's stockholders approve the merger at the meeting, the companies expect to close the transaction shortly after the meeting is completed.

In their consent decree with the DOJ, JDS Uniphase and E-TEK have agreed to relinquish, over a 90-day transition period, E-TEK's contractual rights of first refusal with respect to the output from coating chambers used for the manufacture of thin-film filters owned by Barr Associates, Herrmann Technology, Inc., Hoya Corporation USA, and OCJ Corporation (the "Filter Vendors"). Specifically, at the end of 30 days following today's signing of the consent decree, the companies have agreed not to enforce E-TEK's rights of first refusal with respect to 30% of each Filter Vendor's filter manufacturing capacity subject to those rights. After the second thirty days of the transition period, the companies shall not enforce E-TEK's rights of first refusal with respect to 60% of such manufacturing capacity; and at the expiration of the transition period, the companies shall not enforce any rights of first refusal remaining in E-TEK's supply agreements with the Filter Vendors.

The parties have also agreed not to enforce E-TEK's security interests and rights of repayment included in supply agreements E-TEK has with the Filter Vendors, for whom E-TEK has financed the purchase of coating chambers.

Finally, JDS Uniphase and E-TEK have agreed not to reacquire, directly or indirectly, any rights of first refusal over coating chambers currently owned by or located on the premises of the Filter Vendors for three years from expiration of the 90-day transition period. JDS Uniphase and E-TEK are free, however, to continue issuing purchase orders in the normal course of business to the Filter Vendors, as long as the delivery period for filters under those purchase orders is no longer than 30 days during the transition period, and 60 days for the three years after expiration of the transition period. Existing purchase orders are not affected by the consent decree.

"We are delighted to reach this agreement with the Department of Justice, which permits the companies to close our merger on schedule," said Jozef Straus, JDS Uniphase Co-Chairman and Chief Executive Officer. "As we have said all along, the driving force behind this merger is the promise of dramatically increased production of optical networking components which our customers urgently need. We are pleased that the DOJ has concluded its investigation and is permitting the industry to begin realizing the many benefits of this merger."

The special meeting will be held at E-TEK's headquarters at 1865 Lundy Avenue, San Jose, California at 8:00 AM Pacific Time on June 28, 2000. Stockholders of record as of the close of business on May 22, 2000 will be entitled to vote at the meeting. E-TEK stockholders have already been sent a copy of the proxy statement and JDS Uniphase's prospectus as filed with the Securities and Exchange Commission on May 31, 2000. Under the merger agreement, E-TEK stockholders would receive 2.2 shares of JDS Uniphase common stock for each share of E-TEK common stock.
