On June 5, 2012, Oclaro, Inc. (the “Company”) announced the appointment of Jim Haynes to the position of President, Global Business and Terry Unter to the position of Chief Operating Officer while Yves LeMaitre will remain in his current role as Chief Commercial Officer. These appointments are being made as the Company proceeds toward closing its previously announced merger with Opnext, Inc. in order to further ensure a smooth integration of the two companies.

Separately, Opnext announced on June 4, 2012, that the Opnext Board of Directors had reviewed an offer by a private equity firm for $1.40 per share of Opnext common stock and determined that offer to be inferior to the expected shareholder value of combining Oclaro and Opnext. On April 23, 2012, Oclaro and Opnext were notified that the Federal Trade Commission and the Antitrust Division of the Department of Justice granted the parties’ request for early termination of the HSR waiting period, effective as of that date.
