9.3No Right to Employment. Nothing in the Plan or in any notice of Award shall confer upon any person the right to continue in the employment of the Company or any Subsidiary or affect the right of the Company or any Subsidiary to terminate the employment of any Participant.

9.4No Right to Award. Unless otherwise expressly set forth in an employment agreement signed by the Company and a Participant, a Participant shall not have any right to any Award under the Plan until such Award has been paid to such Participant and participation in the Plan in one Performance Period does not connote any right to become a Participant in the Plan in any future Performance Period.

9.5Withholding. The Company shall have the right to withhold from any Award, any federal, state or local income and/or payroll taxes required by law to be withheld and to take such other action as the Committee may deem advisable to enable the Company and Participants to satisfy obligations for the payment of withholding taxes and other tax obligations relating to an Award.

part. Notwithstanding the foregoing, no amendment shall adversely affect the rights of any Participant to Awards allocated prior to such amendment, suspension or termination.

Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between the Company and any Participant, beneficiary or legal representative or any other person. To the extent that a person acquires a right to receive payments under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company. All payments to be made hereunder shall be paid from the general funds of the Company and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in the Plan. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974, as amended (ERISA).

If no such beneficiary has been designated or survives the Participant, payment shall be made by will or the laws of descent or distribution.

9.10Section 409A of the Code. It is intended that payments under the Plan qualify as short-term deferrals exempt from the requirements of Section 409A of the Code. In the event that any Award does not qualify for treatment as an exempt short-term deferral, it is intended that such amount will be paid in a manner that satisfies the requirements of Section 409A of the Code. The Plan shall be interpreted and construed accordingly.

9.11Expenses. All costs and expenses in connection with the administration of the Plan shall be paid by the Company.

9.12Section Headings. The headings of the Plan have been inserted for convenience of reference only and in the event of any conflict, the text of the Plan, rather than such headings, shall control.

9.13Severability. In the event that any provision of the Plan shall be considered illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, but shall be fully severable, and the Plan shall be construed and enforced as if such illegal or invalid provision had never been contained therein.

9.17Successors. All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding upon any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation or otherwise, of all or substantially all of the assets of the Company.

9.18Clawback. All Awards for Executive Officers are subject to the Company's Clawback Policy as in effect from time to time and, in accordance with such policy, may be subject to the requirement that the Awards be repaid to the Company after they have been distributed to the Participant.

The action permitted to be taken by the Board under this Section 9.18 is in addition to, and not in lieu of, any and all other rights of the Board and/or the Company under applicable law and shall apply notwithstanding anything to the contrary in the Plan.
