WHEREAS, on the date of grant of each SAR, the Employee had previously entered into that certain Employment Agreement entered into as of February 4, 2008, effective as of April 2, 2008, by and between Mandalay Corp. and MAC, CORP. and the Employee, as amended effective January 1, 2009 (the “Employment Agreement”) which contained certain terms relating to SARs;

WHEREAS, the Company has determined that the SAR Agreements did not reflect the Company’s intent with respect to the treatment of the SARs upon certain terminations of employment of the Employee; and

Notwithstanding anything to the contrary contained in this Agreement, the Employment Agreement entered into as of February 4, 2008, effective as of April 2, 2008, by and between Mandalay Corp. and MAC, CORP. and the Participant, as amended effective as of January 1, 2009 (the “Employment Agreement”) or otherwise,

A. with respect to any continued vesting and exerciseability of the SAR which the Participant may be eligible to receive under Section 10 of the Employment Agreement that is determined, in whole or in part, by reference to a period of inactive status (including, without limitation, during the term of an expired or superseded agreement, as applicable), the continued vesting and exercise period shall be

determined, in whole or in part, as applicable, by reference to a period of inactive status, if any, as provided under the Participant’s employment agreement with the Company or any of its affiliates (including, without limitation, any Parent or Subsidiary) in effect as of the applicable date of determination; provided, that such period shall in no event exceed the term of the SAR as set forth in Section 3.1.A of this Agreement.

B. with respect to any accelerated vesting of the SAR which the Participant may be eligible to receive under Section 10 of the Employment Agreement that is calculated, in whole or in part, by reference to the remaining portion of the “Specified Term” (including, without limitation, during the term of an expired or superseded agreement, as applicable), the accelerated vesting shall be calculated, in whole or in part, as applicable, by reference to the remaining portion of the “Specified Term,” if any, of the Participant’s employment agreement with the Company or any of its affiliates (including, without limitation, any Parent or Subsidiary) in effect as of the applicable date of determination.”

2. Except as specifically amended hereby, the SAR Agreements shall remain in full force and effect as originally executed.

3. This Amendment may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.
