Item 2.01 Completion of Acquisition or Disposition of Assets

On August 3, 2005, JDS Uniphase Corporation (the “Company”) announced via press release that it completed its acquisition, by way of merger (the “Merger”), of privately held Acterna, Inc. (“Acterna”) on a cash-free, debt-free basis for approximately $450 million in cash and 200,467,802 shares of JDS Uniphase common stock (the “Shares”). Acterna is a leading worldwide provider of broadband and optical test and measurement solutions for telecommunications and cable service providers and network equipment manufacturers. As a result of the Merger, Acterna became a wholly-owned subsidiary of the Company.

Item 3.02 Unregistered Sales of Equity Securities

The Shares delivered to Acterna’s stockholders’ and option holders at the closing of the Merger were issued in reliance on an exemption from registration under Section 3(a)(10) of the Securities Act of 1933, as amended, pursuant to a permit issued to the Company by the California Department of Corporations (the “DOC”) in connection with a qualification by permit application filed by the Company with the DOC for the offer and sale of the Shares. The DOC issued said permit after determining, pursuant to a hearing held before the DOC, that the terms and conditions of the offer and sale of the Shares were fair.
