(a)

In the event that the Grantee shall cease to be a director of the Company for any reason other than death or removal, the Option shall be exercisable to the extent exercisable at the date the Optionee ceased to be a director, for a period not to exceed three (3) months following the date that Grantee ceased to be a director. In the event Grantee has been removed as a director of the Company by action of its Board of Directors, this Option and any and all rights hereunder shall automatically terminate as of the date of any such removal.

(b)

In the event of the death of the Grantee while the Grantee is a director of the Company or within the three (3) month period after termination of such status during which Grantee is permitted to exercise the Option as set forth in paragraph (a) of this Article IV, such Option may be exercisable by Grantee’s Successor, to the extent exercisable at the date Grantee ceased to be a director, for a period of one (1) year from the date of death of Grantee or the date Grantee ceased to be a director of the Company, whichever the first shall occur.

(d)

In no event shall any Option or installment granted herein become exercisable by the Grantee or Successor of the Grantee at any time after the date the Grantee ceases to be a director of the Company, for any reason whatsoever, unless such Option or installment is then exercisable at the date of such cessation.

(e)

Except as otherwise herein provided, exercise of this Option or any installment hereunder by the Grantee or the Successor of the Grantee, shall be subject to all terms and conditions of this Agreement.

(a)

In the event of an increase in the number of outstanding shares of Common Stock due to a change in capitalization occurring through a stock dividend or a stock split, there shall be a proportionate increase in the number of Optioned Shares which remain exercisable under this Agreement and a proportionate reduction in the Option Price; provided, however, that any fractional shares of Stock resulting from such adjustment shall be eliminated. In the event of any change in capitalization other than those considered above, the Board shall make such adjustments in the number of Optioned Shares which remain exercisable under this Agreement, and in the Option Price, as the Board in its discretion may consider appropriate, and all such adjustments shall be conclusive upon all persons, provided that no change shall be made in the terms of this Option which would disqualify it from treatment under Section 421 of the Code or would be considered a modification, extension, or renewal of the Option under Section 424 of the Code.

(b)

In the event that the shares of Stock shall be exchanged for or replaced by shares of stock of another corporation by reason of a corporate merger, consolidation, acquisition of property or stock, separation, reorganization or liquidation, or other corporate transactions involving the Company, there shall be substituted for the number of Optioned Shares which remain exercisable under this Agreement that number of shares of stock of such corporation which is proportionate to such number of Optioned Shares in accordance with the terms of the exchange; and there shall be made such other changes in the number, kind or price of the Optioned Shares which remain exercisable under this Agreement as shall be necessary to give effect to the intent of this Article V.

(a)

Grantee understands that (i) the Grantee shall not have any rights as a stockholder with respect to any Common Stock received upon exercise of this Option until such Common Stock has been actually issued to the Grantee in accordance with the terms hereof; and (ii) nothing in this Agreement or the Plan shall confer on Grantee any right to continue as a director of the Company.

(b)

Anything herein to the contrary notwithstanding, the Company may postpone the exercise of this Option for such time as the Board of Directors or the Committee in its discretion may deem necessary, in order to permit the Board of Directors or the Committee with reasonable diligence (i) to effect or maintain registration under the Securities Act of 1933, as amended (the “Act”), of the Plan or the shares of Common Stock issuable upon the exercise of this Option, or (ii) to determine that the Plan and such shares are exempt from registration; and the Company shall not be obligated by virtue of this Option or to sell or issue shares of Common Stock in violation of the Act or of the law of any applicable jurisdiction. Any such postponement shall not extend the Term of this Option; and neither the Company nor its Board nor the Committee shall have any obligation or liability to the Grantee or to the Grantee’s Successor, with respect to any shares of Common Stock as to which this Option shall lapse because of such postponement.

(c)

Subject to Article IV of this Agreement, this Option shall be non-transferable and non-assignable except by will and by the law of descent and distribution. During the Grantee’s lifetime, this Option may be exercised only by the Grantee.

(d)

The Grantee agrees that in the event Grantee makes any sale or other disposition of the Shares of Common Stock issued upon exercise of this Option that Grantee shall promptly notify the Company of such sale or disposition and shall furnish the Company with such information concerning such sale or disposition as may be requested by the Company.

(e)

As a condition of the granting of this Option, the Grantee or Successor of the Grantee agrees that any dispute or disagreement which may arise hereunder shall be determined by the Board of Directors or the Committee in its sole discretion and judgment, and that any such determination and any interpretation by the Board of Directors or the Committee of the terms of this Agreement shall be final and binding and conclusive, for all purposes, upon the Company, the Grantee or the Successor of the Grantee.

(f)

The Company shall have the right to require the Grantee to remit to the Company an amount sufficient to satisfy any federal, state and local withholding tax requirement prior to the delivery of any shares of Common Stock acquired by exercise of the Option granted hereunder. In each case of exercise of an installment of the Option, the Company will notify the Grantee of the amount of the withholding tax, if any, under federal and, where applicable, state and local law. Upon receipt of such notice, the Grantee shall promptly remit to the Company the amount specified in such notice.

(g)

Any notice given by the Company to the Grantee shall be effective to bind any person who shall acquire rights hereunder. The Company shall be under no obligation whatsoever to advise the Grantee of the existence, maturity or termination of any of the Grantee’s rights hereunder and the Grantee shall be deemed to have familiarized himself/herself with all matters contained herein and in the Plan which may affect any of the Grantee’s rights and privileges hereunder.

(h)

This Agreement is subject to the Plan and its terms and provisions (including any subsequent amendments thereto) which Plan and its terms and provisions are by this reference hereby incorporated herein. In the event of a conflict between any term or provision contained herein and a term or a provisions of the Plan, the applicable terms and provisions of the Plan will govern and prevail.
