B. Pursuant to this Amendment, the Company and Executive have agreed to a clarifying amendment to the Agreement, which amendment is intended to align the meaning of the term "Stock Award" with the terms used in the Company's current equity incentive programs as well as the original intent of the parties.

2. All provisions of the Agreement, as amended by this Amendment, remain in full force and effect. After this Amendment becomes effective, all references in the Agreement to "this Agreement", "hereof', "herein" or words of similar effect referring to the Agreement shall be deemed to be references to the Agreement, as amended by this Amendment.

3. This Amendment shall not be deemed to expressly or impliedly waive, amend or supplement any provision of the Agreement, other than as set forth herein.

4. This Amendment may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument.

5. This Amendment shall be governed by, and construed in accordance with, the laws of the State of California, without regard to such state's of conflict of laws rules.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the date set forth in the first paragraph hereof.
