The following constitutes Amendment No. 10 to the Schedule 13D filed by the undersigned (“Amendment No. 10”). This Amendment No. 10 amends the Schedule 13D as specifically set forth herein.

Item 5.

Interest in Securities of the Issuer.

Item 5 is hereby amended and restated to read as follows:

(a)-(d) On June 23, 2014, the Issuer, Avago Technologies Wireless (U.S.A.) Manufacturing Inc., a Delaware corporation (“Parent”), and Pluto Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Purchaser”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the Merger Agreement, on July 8, 2014, Purchaser commenced a tender offer (the “Offer”) to purchase all of the outstanding Shares of the Issuer at a price of $6.50 per Share, in cash, without interest and subject to any applicable withholding of taxes. The Offer expired on August 11, 2014 and, all the conditions to the Offer having been satisfied (or waived), Purchaser accepted for payment all such Shares validly tendered and not properly withdrawn, including the 4,683,278 Shares owned by the Reporting Persons. Following consummation of the Offer, on August 12, 2014, Parent completed its acquisition of the Issuer by consummating the Merger Agreement. As a result of the foregoing, the Reporting Persons no longer beneficially own any securities of the Issuer.

(e) The Reporting Persons ceased to be the beneficial owners of more than 5% of the Shares of the Issuer as of August 12, 2014.
