Company owned by the undersigned beneficially and of record as of the date hereof, which shares are listed on Schedule I to this Proxy, and (ii) any and all shares of capital stock of the Company acquired (and owned beneficially and of
record) by the undersigned on or after the date hereof (collectively, the “Owned Shares”), until the Expiration Date (as defined below). As used herein, the term “Expiration Date” shall mean the earliest to occur

Japanese corporation (“Parent”), Merger Sub, and the Company (the “Merger Agreement”) shall become effective, (B) the termination of the Merger Agreement in accordance with its terms and (C) an agreement

Company and in every written consent in lieu of such meeting, (x) in favor of the adoption and approval of the Merger Agreement and the Merger and the approval of the terms thereof and each of the other actions contemplated by the Merger
Agreement and the Support Agreement dated as of July 31, 2007 (the “Support Agreement”), including any other action reasonably required in furtherance thereof, (y) against any action (including, without limitation, any
motion to adjourn or postpone a meeting of stockholders of the Company at which any matters contemplated by the Merger Agreement or Support Agreement (collectively, the “Transaction Documents”) are to be presented to a vote of such
stockholders), transaction or agreement that would result in a breach in any respect of or would otherwise be inconsistent with any covenant, representation or warranty or any other obligation or agreement of the Company in any Transaction Document
to which it is a party, or of such Stockholder under the Support Agreement, and (z) without limiting the preceding clause (y) and except as otherwise agreed to in writing in advance by Merger Sub, against the following actions (other than

consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company or any of its respective Subsidiaries (as defined in the Support Agreement); (ii) approval or consent regarding any
Acquisition Transaction (as defined in the Support Agreement); (iii) any change in the Persons (as defined in the Support Agreement) who constitute the board of directors of the Company other than filling vacancies in connection with voluntary

or adversely affect the Merger or any of the transactions contemplated by the Transaction Documents or any other agreement referred to therein.
