Neither the action of the Company in establishing the Plan nor any action taken by the Company under the provisions hereof, nor any provision of the Plan, shall be construed as giving to the Participant the right to be retained in its employ or any right to any payment whatsoever except to the extent of the benefits

provided for by the Plan. The Company expressly reserves its right at any time to dismiss the Participant without liability for any claim against the Company for any payment whatsoever, except to the extent provided for in the Plan. Notwithstanding the immediately preceding sentence, the Company shall not pay out to the Participant any benefits provided under this Plan in the event that the Participant is terminated for Cause as such term is defined in Section 9 hereunder.

Section 17. Amendment.

The Plan may be altered, amended, or revoked in writing by the Company at any time, but such action may not reduce the Company’s obligation with respect to the Participant below the amount to which he would be entitled under the Plan as in effect immediately prior to such alteration, amendment, or revocation. Except as may be permitted under Code Section 409A, no alteration, amendment or revocation of the Plan shall directly or indirectly accelerate a distribution to any Participant and the Company’s obligation to the Participant shall continue until the obligation lapses in accordance with the terms of the Plan immediately prior to such alteration, amendment or revocation.
