Explanation of Responses:

( 1 )Shares sold by the Attiyeh Community Property Trust and not reported at the time of sale. ( 2 )On January 13, 2015, Infineon Technologies AG., a stock corporation (Aktiengesellschaft) organized under the laws of the Federal Republic of Germany ("Infineon"), acquired the issuer pursuant to that certain agreement and plan of merger among issuer, Infineon and Surf Merger Sub, Inc., a Delaware corporation and wholly owned subsidiay of Infineon ("Merger Sub"), dated as of August 20, 2014 (the "Merger Agreement"). In accordance with the Merger Agreement, Merger Sub merged with and into the issuer (the "Merger"), with the issuer surviving the Merger as a wholly owned subsidiary of Infineon. At the effective time of the Merger, each outstanding share of the issuer's common stock was converted into the right to receive $40.00 in cash (the "per-share merger consideration"). The Merger is more fully described in the issuer's Proxy Statement filed with the SEC on October 7, 2014. ( 3 )These service-based Restricted Stock Units, which provide for vesting on the first anniversary of the date of grant were cancelled at the effective time of the Merger, in exchange for a cash amount equal to the per-share merger consideration multiplied by the number of Restricted Stock Units to be paid out as soon as administratively practicable following the effective time of the Merger.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
