On June 17, 2011, pursuant to an Agreement and Plan of Merger dated as of February 4, 2011 by and among the Registrant, GigOptix, Inc., a Delaware corporation (“GigOptix”) and Aerie Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of GigOptix (“Merger Sub”) (the “Merger Agreement”), Merger Sub merged with and into Registrant, with Registrant being the surviving entity (the “Merger”).

As a result of the Merger, the Registrant has terminated all offerings of the Registrant’s securities pursuant to the above referenced Registration Statement. Accordingly, pursuant to the undertakings contained in such Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities being registered which remain unsold at the termination of the offering, the Registrant is filing this post-effective amendment to the Registration Statement to deregister all the shares of the Registrant’s common stock registered and reserved for issuance under such Registration Statement which remained unissued as of the Effective Time.
