2. Revenue Target Payments.
1. In the event the Company's Revenue equals or exceeds Revenue Target A for the applicable Annual Period, the Company shall pay the Eligible Participants an aggregate amount of cash equal to 25% of the Revenue Pool which shall be distributed equally among the Eligible Participants, subject to Section 7 below.
2. In addition to the payment under Section 6(b)(i):
1. In the event the Company's Revenue equals or exceeds Revenue Target B for the applicable Annual Period, the Company shall pay the Eligible Participants an aggregate amount of cash equal to 75% of the Revenue Pool ("Target B Revenue Payout") which shall be distributed among the Eligible Participants in accordance with Sections 6(d) and 7 below.
2. In the event the Company's Revenue equals or exceeds Revenue Target A but is less than Revenue Target B for the applicable Annual Period, the Company shall pay the Eligible Participants an aggregate amount of cash equal to (x) the quotient of the amount of Revenue recognized by the Company in excess of Revenue Target A divided by the difference of Revenue Target B minus Revenue Target A, multiplied by (y) the Target B Revenue Payout which shall be distributed among the Eligible Participants in accordance with Sections 6(d) and 7 below.

For example, assuming a Target B Revenue Payout of $200,000, a Revenue Target A of $100,000,000 and a Revenue Target B of $120,000,000, if the Company's Revenue were $110,000,000, then the aggregate payment under Section 6(b)(ii)(2) would be:

110,000,000 - 100,000,000
-------------------------------- x $200,000 = $100,000
120,000,000 - 100,000,000

3. Net Income Target Payments.
1. In the event the Company's Adjusted Net Income equals or exceeds Net Income Target A for the applicable Annual Period, the Company shall pay the Eligible Participants an aggregate amount of cash equal to 25% of the Net Income Pool which shall be distributed equally among the Eligible Participants, subject to Section 7 below.
2. In addition to the payment under Section 6(c)(i):
1. In the event the Company's Adjusted Net Income equals or exceeds Net Income Target B for the applicable Annual Period, the Company shall pay the Eligible Participants an aggregate amount of cash equal to 75% of the Net Income Pool ("Target B Net Income Payout") which shall be distributed among the Eligible Participants in accordance with Sections 6(d) and 7 below.

2. In the event the Company's Adjusted Net Income equals or exceeds Net Income Target A but is less than Net Income Target B for the applicable Annual Period, the Company shall pay the Eligible Participants an aggregate amount of cash equal to (x) the quotient of the amount of Net Income realized by the Company in excess of Net Income Target A divided by the difference of Net Income Target B minus Net Income Target A, multiplied by (y) the Target B Net Income Payout which shall be distributed among the Eligible Participants in accordance with Sections 6(d) and 7 below.

For example, assuming a Target B Net Income Payout of $200,000, a Net Income Target A of $10,000,000 and a Net Income Target B of $12,000,000, if the Company's Net Income were $11,000,000, then the aggregate payment under Section 6(c)(ii)(2) would be:

11,000,000 - 10,000,000
-------------------------------- x $200,000 = $100,000
12,000,000 - 10,000,000

4. The allocation of any Target B Revenue Payout and Target B Income Revenue Payout (or any portion thereof earned under Section 6(b)(ii)(2) or 6(c)(ii)(2) above) payable under this Section 6 among the Participants shall be determined by the Board, in its sole discretion, on the Award Determination Date based on the contributions of each Participant towards the attainment of Revenue Target B and Net Income Target B, respectively. In weighing the contributions of each Participant for such purpose, the Board may consider subjective factors including, without limitation, each Participant's initiative, leadership, teamwork, judgment and creativity.
7. Termination of Employment. Except to the extent otherwise provided by the Committee, if a Participant's employment with the Company, any Subsidiary or any Affiliate, is terminated for any reason prior to the Award Determination Date, then, except in the case of death, disability or normal retirement, or an involuntary termination due to a reduction in force, or except as provided in Section 13, the Participant shall forfeit the Award and shall not be entitled to a payment of the Award. If a Participant's employment is terminated after the last day of the Annual Period but prior to the Award Determination Date due to death, disability, normal retirement or involuntary termination caused by a reduction in force, the Participant shall be entitled to full payment of the Award that would have been payable if the Participant had been a Participant on the Award Determination Date, based upon the Committee's determination as to whether the applicable Target or Targets are achieved within such Annual Period. If a Participant's employment is terminated during the Annual Period due to death, disability, normal retirement or involuntary termination caused by a reduction in force, the Participant shall be entitled to a pro-rated payment of the Award that would have been payable if the Participant had been a Participant on the Award Determination Date, based upon the Committee's determination as to whether the applicable Target or Targets are achieved within such Annual Period. If a Participant is entitled to a payment of the Award pursuant to the preceding sentence, such amount shall be pro-rated based on the number of days the individual was a Participant in the Plan for such Annual Period and shall be paid at the same time and in the same manner as such payment would have been made if the Participant had been a Participant on the Award

6

Determination Date. A leave of absence, approved by the Committee, shall not be deemed to be a termination of employment for purposes of this Plan.

8. Unfunded Plan. The Plan is intended to constitute an "unfunded" plan for incentive compensation, and the Plan is not intended to constitute a plan subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company. In its sole discretion, the Committee may authorize the creation of trusts or other arrangements to meet the obligations created under the Plan to deliver payments hereunder, provided, however, that the existence of such trusts or other arrangements is consistent with the unfunded status of the Plan.
9. Non-Alienation of Benefits; Beneficiary Designation. All rights and benefits under the Plan are personal to the Participant and neither the Plan nor any right or interest of a Participant or any other person arising under the Plan is subject to voluntary or involuntary alienation, sale, transfer, or assignment without the Company's consent. Subject to the foregoing, the Company shall establish such procedures as it deems necessary for a Participant to designate one or more beneficiaries to whom any payment the Committee determines to make would be payable in the event of the Participant's death. In the event no beneficiary has been properly designated, the payment shall be made to the Participant's surviving spouse or, if none, the Participant's estate.
10. Withholding for Taxes. Notwithstanding any other provisions of this Plan, the Company shall have the authority to withhold from any payment made by it under the Plan such amount or amounts as may be required for purposes of complying with any Federal, state and local tax or withholding requirements.
11. No Right to Continued Employment or to Participate. Nothing contained in the Plan or in any Award shall confer upon any recipient of an Award any right with respect to the continuation of his or her employment with the Company (or any Affiliate), or interfere in any way with the right of the Company, subject to the terms of any separate employment or consulting agreement or provision of law or corporate articles or by-laws to the contrary, at any time to terminate such employment or consulting agreement or to increase or decrease, or otherwise adjust, the other terms and conditions of the recipient's employment with the Company and its Affiliates.
12. Non-Exclusivity of Plan. The adoption of the Plan by the Board shall not be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including without limitation, the granting of stock options and restricted stock other than under the Plan, and such arrangements may be either applicable generally or only in specific cases
13. Change of Control. Notwithstanding anything to the contrary provided elsewhere herein, in the event of a Change of Control of the Company then the Company shall as promptly as practicable following the effective date of the Change of Control pay any incentive Awards payable to Participants. The payment to each Participant shall be an amount not less than the target Award as originally approved for the Annual Period, notwithstanding actual results or any changes or modifications occurring after any such Change of Control.

14. Impact of Restatement of Financial Statements upon Previous Awards.
1. If any of the Company's financial statements are restated due to the material noncompliance of the Company with any financial reporting requirement under applicable securities laws as a result of misconduct or otherwise, each Participant shall be required to reimburse the Company for any payments under this Plan that the Company is required to recover from such Participant or that such Participant is required to reimburse the Company under any policies adopted by the Board or any committee thereof from time to time or under applicable law, including without limitation Section 304 of the Sarbanes-Oxley Act of 2002, Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the respective rules and regulations thereunder.
2. The Committee shall determine, in accordance with applicable law, whether the Company shall effect any such recovery (i) by seeking repayment from the Participant, (ii) by reducing (subject to applicable law and the terms and conditions of the applicable plan, program or arrangement) the amount that would otherwise be payable to the Participant under any compensatory plan, program or arrangement maintained by the Company, a Subsidiary or any of its Affiliates, (iii) by withholding payment of future increases in compensation (including the payment of any discretionary bonus amount) or grants of compensatory awards that would otherwise have been made in accordance with the Company's otherwise applicable compensation practices, or (iv) by any combination of the foregoing or otherwise.
15. Amendment or Termination. The Board may at any time terminate the Plan or make such modifications of the Plan as it shall deem advisable. Unless the Board otherwise expressly provides, no amendment of the Plan shall affect the terms of any Award outstanding on the date of such amendment. The Committee may amend the terms of any Award theretofore granted, prospectively or retroactively, provided that the Award as amended is consistent with the terms of the Plan.
16. Application of Code Section 409A. This Plan is intended to be administered and interpreted in a manner such that it is exempt from the requirements of Section 409A of the Code pursuant to the "short term deferral rule." Notwithstanding the foregoing, no particular tax result with respect to any income recognized by a Participant in connection with the Plan is guaranteed and each Participant shall be responsible for any taxes imposed on him in connection with the Plan.
17. Governing Law and Interpretation. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of California, without regard to the conflicts of law principles thereof. Unless otherwise indicated, all "Section" references are to sections of the Plan. References to any law, rule or regulation shall include all statutory and regulatory provisions consolidating, amending, replacing, supplementing, or interpreting such law, rule or regulation.
18. Severability. If any one or more of the provisions contained in this Plan shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

19. Effective Date. This Plan shall become effective immediately with respect to the Annual Period ending March 31, 2012 upon approval of the Board and shall remain effective, subject to the right of the Board to terminate the Plan, on a prospective basis only, at any time.
