5. Annual Performance Bonus Awards.

(a) Each Participant shall be eligible to receive such Annual Performance Bonus Award, if any, for each Fiscal Year as may be payable pursuant to the performance criteria described below. Annual Performance Bonus Awards consist of cash amounts payable upon the achievement during a Fiscal Year of specified objective performance goals. Within the first 90 days of the Fiscal Year, the Committee will establish the performance goals and the amounts to be paid if the performance goals are achieved. The Annual Performance Bonus Award, if any, for each Participant will be determined as a percentage of the Participant’s Base Salary. The maximum Annual Performance Bonus Award that may be awarded to a Participant for a Fiscal Year shall be 300% of the Participant’s Base Salary for such Fiscal Year.

(b) Participants shall have their Annual Performance Bonus Awards, if any, determined on the basis of the degree of achievement of performance goals which shall be established by the Committee in writing and which goals shall be stated in terms of the attainment of specified levels of or percentage changes in any one or more of the following measurements.

The Committee shall, for each Fiscal Year, establish the performance goal or goals from among the foregoing to apply to each Participant and a formula or matrix prescribing the extent to which such Participant’s annual performance bonus award shall be earned based upon the achievement of such performance goal or goals.

(c) Each Annual Performance Bonus Award shall be based solely on achievement of one or more of the applicable performance goals as established by the Committee pursuant to Section 5(a) above and the Committee shall not have the discretion to increase the amount of the Annual Performance Bonus Award. No Annual Performance Bonus Award shall be payable except upon written certification by the Committee that the performance goals have been satisfied to a particular extent and that any other material terms and conditions precedent to payment of an Annual Performance Bonus Award have been satisfied.

(d) Payment of any Annual Performance Bonus Award amount to be paid to a Participant based upon the degree of attainment of the applicable performance goals shall be made at such time(s) as the Committee may in its discretion determine. However, the Award amount shall be paid in full within 30 days after the public release of its audited results.

6. Participant’s Interests. A Participant’s interest in any Awards shall at all times be reflected on the Firm’s books as a general unsecured and unfunded obligation of the Firm subject to the terms and conditions of the Plan. The Plan shall not give any person any right or security interest in any asset of the Firm or any fund in which any deferred payment is deemed invested. Neither the Firm, the Board, nor the Committee shall be responsible for the adequacy of the general assets of the Firm to discharge, or required to reserve or set aside funds for, the payment of its obligations hereunder.

7. 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. Subject to the foregoing, the Firm 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.

8. Withholding for Taxes. Notwithstanding any other provisions of this Plan, the Firm may 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.

9. Rights of Employees. Nothing in the Plan shall interfere with or limit in any way the right of the Firm to terminate a Participant’s employment at any time, or confer upon any Participant any right to continued employment with the Firm or any of its subsidiaries or affiliates.

10. Determinations Final. Each determination provided for in the Plan shall be made by the Committee under such procedures as may from time to time be prescribed by the Committee and shall be made in the sole discretion of the Committee. Any such determination shall be conclusive.

11. Adjustment of Awards. The Committee shall be authorized to make adjustments in the method of calculating attainment of performance goals in recognition of unusual or nonrecurring events affecting the Firm or its financial statements or changes in applicable laws, regulations or accounting principles; provided, however, that no such adjustment shall impair the rights of any Participant without his consent and that any such adjustments with respect to Annual Performance Bonus Awards shall be made in a manner consistent with Section 162(m) of the Code.

12. Amendment or Termination. The Board may, in its sole discretion, amend, suspend or terminate the Plan from time to time. No such termination or amendment shall alter a Participant’s right to receive a distribution as previously earned, as to which this Plan shall remain in effect following its termination until all such amounts have been paid, except as the Firm may otherwise determine.
