9.3 Deferral of Payments. If permitted by the Committee, a Participant may be eligible to elect to defer receipt of payments that would otherwise be provided to such Participant with respect to an Award under the Plan. If permitted, such deferral (and the required deferral election) shall be made in accordance with, and shall be subject to, the terms and conditions of the applicable deferred compensation plan under which such deferral is made and such other terms and conditions as the Committee may impose.

Article 10. Beneficiary Designation

Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any payment under the Plan is to be made in case of his or her death before he or she receives any or all of such payment. Each designation will revoke all prior designations by the same Participant, shall be in a form prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Committee during his or her lifetime. In the absence of any such designation, benefits remaining unpaid at the Participant’s death shall be paid to the Participant’s estate.

Article 11. Amendment, Suspension and Termination

The Committee may, at any time and from time to time, modify or amend, in whole or in part, any or all of the provisions of the Plan, or suspend or terminate it entirely; provided, however, that no such modification, amendment, suspension or termination of the Plan and no amendment of an Award pursuant to Section 3.2 herein may adversely affect in any material way any Award previously granted under the Plan without the consent of the Participant (or his or her devisee or beneficiary in the case of the death of the Participant), unless such modification, amendment, suspension or termination is required by applicable law and except as otherwise provided herein.

Article 12. Miscellaneous

12.1 Governing Law. The Plan, and all agreements hereunder, shall be governed by and construed in accordance with the laws of the state of Delaware.

13

12.3 Nontransferability. Except as otherwise provided in a Participant’s Award Agreement and in Article 9 herein, no interest in a Participant’s Award or Award Bank may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.

12.4 Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular, and the singular shall include the plural.

12.5 Severability. In the event any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

12.6 Costs of the Plan. All costs of implementing and administering the Plan shall be borne by the Enterprise.

12.7 Successors. All obligations of the Enterprise under the Plan shall be binding upon and inure to the benefit of any successor to the Enterprise, 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 business and/or assets of the Enterprise.

12.8 Limitations on Executive Compensation. To the extent that any applicable law, rule or regulation requires a limitation upon executive compensation or restricts the deductible amount of any Award, the Committee may, in its sole discretion, limit the amount of any payment under this Plan in accordance with such limitations.

12.9 Section 409A Compliance. To the extent applicable, it is intended that the terms of an Award (and any deferral thereof) comply with the requirements of Section 409A. Any provision in this Plan (and any rights conveyed hereby or thereby) or an Award Agreement that would cause an Award and any amounts payable with respect to such Award (or any other plan or award) to fail to satisfy Section 409A shall have no force or effect until amended to comply with Section 409A, which amendment may be retroactive to the extent permitted by Section 409A.

12.10 Six Month Delay for Specified Executives. If a Participant is a Specified Executive under Section 409A, payment of amounts under this Plan may be delayed for up to six months following Termination of Employment if (and to the extent) deemed necessary by the Committee to comply with Section 409A, subsection (a)(2)(B).
