On February 10, 2010, JDS Uniphase Corporation, a Delaware corporation (“JDSU”), entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Agilent Technologies, Inc., a Delaware corporation (“Agilent”). Under the terms of the Asset Purchase Agreement, JDSU will acquire substantially all of the assets of Agilent and its affiliates that relate to the design, development, research, manufacture, supply, distribution, sale, support and maintenance of the Agilent Network Protocol Test Products, Agilent Wireless Drive Test Systems and Agilent Network Service Assurance and Test Systems (excluding the Agilent N2X and Agilent Network Tester products) and the provision of services relating to such products (the “Business”), and assume certain liabilities of Agilent relating to the Business, for a cash purchase price of $165 million, subject to a post-closing working capital adjustment.

The acquisition is scheduled to close, subject to certain customary closing conditions, upon the receipt of customary government approvals related to anti-trust and competition laws. If the closing has not occurred by August 2, 2010, which may be extended to September 2, 2010, either party may terminate the Asset Purchase Agreement without penalty.

Under the Asset Purchase Agreement, JDSU will offer employment to all employees of the Business. JDSU and Agilent have also entered into a Transition Services Agreement under which Agilent will provide to JDSU, for agreed upon fees and beginning on the date of the closing, certain services through June 30, 2010 and certain other services through August 31, 2010 (subject to earlier termination by JDSU under certain circumstances).

The Asset Purchase Agreement contains customary representations, warranties and covenants. Each party has agreed to indemnify the other for (i) subject to certain limitations, losses arising out of breaches of representations, warranties and covenants in the Asset Purchase Agreement and in certain related documents and (ii) liabilities that, in the case of JDSU, are excluded from the transaction and, in the case of Agilent, are assumed by JDSU.

The foregoing description of the Asset Purchase Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Asset Purchase Agreement, which is filed as Exhibit 2.1 hereto and incorporated by reference into this Current Report on Form 8-K.

On February 11, 2010, JDSU issued a press release, a copy of which is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
