Pursuant to an Agreement and Plan of Merger, dated as of September 19, 2016, by and among Tessera Technologies, Inc., a Delaware corporation (“ Tessera ”), Tessera Holding Corporation (f/k/a Tempe Holdco Corporation), a Delaware corporation and wholly owned subsidiary of Tessera (“ Tessera Holding ”), Tempe Merger Sub Corporation, a Delaware corporation and a wholly owned subsidiary of Tessera Holding and Arizona Merger Sub Corporation, a Delaware corporation and a wholly owned subsidiary of Tessera Holding (“ Merger Sub ”) and the Company, on December 1, 2016, among other things, Merger Sub merged with and into the Company (the “ Merger ”), with the Company surviving the Merger as a wholly owned subsidiary of Tessera Holding.

In connection with the Merger, as of the date hereof, the offerings of Common Stock pursuant to the Registration Statements have been terminated. Accordingly, the Company hereby terminates the effectiveness of each Registration Statement and, in accordance with an undertaking made by the Company in Part II of each Registration Statement to remove from registration, by means of post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offering, the Company hereby removes and withdraws from registration any and all securities of the Company registered but remaining unsold under the Registration Statements as of the date of this Post-Effective Amendment.
