Such options shall, by their terms, be transferable by the optionholder only by the laws of descent and distribution, and shall be exercisable only by such optionholder during his lifetime.

Such options shall not be granted more than ten years from the effective date of this Plan or any subsequent amendment to the Plan approved by the stockholders of the Corporation which extends this Incentive Stock Option expiration date, and shall not be exercisable more than ten years from the date of grant.

Subject to the provisions of the Plan, the Board may award shares of Restricted Stock and determine the duration of the Restricted Period during which, and the conditions under which, the shares may be forfeited to the Corporation and the other terms and conditions of such Awards. Shares of Restricted Stock may be issued for no cash consideration or such minimum consideration as may be required by applicable law.

Shares of Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered, except as permitted by the Board, during the Restricted Period. Shares of Restricted Stock shall be evidenced in such manner as the Board may determine. Any certificates issued in respect of shares of Restricted Stock shall be registered in the name of the Participant and unless otherwise determined by the Board, deposited by the Participant, together with a stock power endorsed in blank, with the Corporation.

Documentation. Each Award under the Plan shall be evidenced by a written document delivered to the Participant specifying the terms and conditions thereof and containing such other terms and conditions not inconsistent with the provisions of the Plan as the Board considers necessary or advisable to achieve the purposes of the Plan or comply with applicable tax and regulatory laws and accounting principles.

Board Discretion. Each type of Award may be made alone, in addition to or in relation to any other type of Award. The terms of each type of Award need not be identical, and the Board need not treat Participants uniformly. Except as otherwise provided by the Plan or a particular Award, any determination with respect to an Award may be made by the Board at the time of award or at any time thereafter.

Settlement. The Board shall determine whether Awards are settled in whole or in part in cash, Common Stock, other securities of the Corporation, Awards, other property or such other methods as the Board may deem appropriate. The Board may permit a Participant to defer all or any portion of a payment under the Plan, including the crediting of interest on deferred amounts denominated in cash and dividend equivalents on amounts denominated in Common Stock. If shares of Common Stock are to be used in payment pursuant to an Award and such shares were acquired upon the exercise of a stock option (whether or not granted under this Plan), such shares must have been held by the Participant for at least six months.

Dividends and Cash Awards. In the discretion of the Board, any Award under the Plan may provide the Participant with (I) dividends or dividend equivalents payable currently or deferred with or without interest, and (ii) cash payments in lieu of or in addition to an Award.

Termination of Employment. The Board shall determine the effect on an Award of the disability, death, retirement or other termination of employment of a Participant and the extent to which, and the period during which, the Participant’s legal representative, guardian or Designated Beneficiary may receive payment of an Award or exercise rights thereunder.

Change in Control. In order to preserve a Participant’s rights under an Award in the event of a change in control of the Corporation, the Board in its discretion may, at the time an Award is made or at any time thereafter, take one or more of the following actions: (I) provide for the acceleration of any time period relating to the exercise or realization of the Award, (ii) provide for the purchase of the Award upon the Participant’s request for an amount of cash or other property that could have been received upon the exercise or realization of the Award had the Award been currently exercisable or payable, (iii) adjust the terms of the Award in a manner determined by the Board to reflect the change in control, (iv) cause the Award to be assumed, or new rights substituted therefore, by another entity, or (v) make such other provision as the Board may consider equitable and in the best interests of the Corporation.

Withholding. The Corporation shall have the power and the right to deduct or withhold, or require a Participant to remit to the Corporation an amount sufficient to satisfy federal, state and local taxes (including the Participant’s FICA obligation) required to be withheld with respect to an Award or any dividends or other distributions payable with respect thereto. In the Board’s discretion, such tax obligations may be paid in whole or in part in shares of Common Stock, including shares retained from the Award creating the tax obligation, valued at their Fair Market Value on the date of delivery. The Corporation and its Affiliates may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to the Participant.

Amendment of Award. The Board may amend, modify or terminate any outstanding Award, including substituting therefore another Award of the same or a different type, changing the date of exercise or realization and converting an Incentive Stock Option to a Nonqualified Stock Option, provided that the Participant’s consent to such action shall be required unless the Board determines that the action, taking into account any related action, would not materially and adversely affect the Participant.

Except as otherwise provided by the Board, Awards under the Plan are not transferable other than as designated by the participant by will or by the laws of descent and distribution.

No Right To Employment. No person shall have any claim or right to be granted an Award, and the

Effective Date. Subject to the approval of the shareholders of the Corporation, the Plan shall be effective on March 11, 1998. Prior to such approval, Awards may be made under the Plan expressly subject to such approval.

Amendment of Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time, provided that no amendment shall be made without shareholder approval if such approval is necessary to comply with any applicable requirement of the laws of the jurisdiction of incorporation of the Corporation, any applicable tax requirement, any applicable rules or regulation of the Securities and Exchange Commission, including Rule 16(b)‑3 (or any successor rule thereunder), or the rules and regulations of the American Stock Exchange or any other exchange or stock market over which the Corporation’s securities are listed.
