The Plan shall become effective on the date it is approved by the Board, unless the Board’s designates another date, and shall apply to Annual Retainers for the 2013 calendar year and subsequent years, subject to suspension, termination or amendment of the Plan pursuant to Section 9. The term of the Plan shall be indefinite.

The maximum number of shares of Common Stock that may be issued under the Plan shall be 100,000 shares, subject to adjustment in accordance with Section 9. The shares of Common Stock issued under the Plan may be authorized and unissued shares of Common Stock and/or authorized and issued shares of Common Stock purchased or acquired by the Company for any purpose.

(a) The number of shares of Common Stock to be received by a director who has elected to receive all or part of his or her Annual Retainer in shares of Common Stock shall be calculated by dividing the dollar amount of the Annual Retainer by the Fair Market Value of one share of Common Stock on the Retainer Payment.

(b) The Company shall pay the Annual Retainer on the Retainer Payment Date.

(c) No fractional shares of Common Stock shall be issued pursuant to the Plan. The number of shares of Common Stock otherwise issuable to an Eligible Director on any Retainer Payment Date, if not a whole number, shall be rounded down to the nearest whole share, and any fractional share otherwise issuable shall be paid in cash.

(d) The Plan is not intended, and shall not be deemed, to limit the authority of the Board or any committee of the Board that is so authorized by the Board to increase or decrease the amount of the Annual Retainer or the period in respect of which it is paid from time to time.

Prior to commencement of each year of service on the Board for which the Annual Retainer is paid, each Eligible Director shall make an Election as to whether his or her Annual Retainer for the next-following year to be paid in shares of Common Stock. The Election shall be made on a form provided to the Eligible Director by the Company for that purpose and that shall be returned to the Committee for receipt prior to the Election Date, and shall be dated and signed by the Eligible Director submitting the form. Any Election that is made in accordance with this Section 7 shall be binding with respect to the year for which the Annual Retainer is payable and all subsequent years unless prior to the Election Date for a subsequent year, the Eligible Director delivers a revocation of his or her Election. The Election shall apply to 100% of the Annual Retainer.

Notwithstanding the foregoing, only with respect to the Annual Retainer for the calendar year 2013 to be paid in April 2013, an Eligible Director may make an Election if such Election is delivered not later than April 30, 2013 and such Eligible Director’s Election to receive Common Stock in respect of the 2013 Annual Retainer is specifically approved by resolution of the Committee or the Board of Directors.

The Plan may be suspended, terminated or reinstated, in whole or in part, at any time by the Board. The Board may from time to time make such amendments to the Plan as it may deem advisable; provided, however, that no amendment shall amend the Plan in a manner that would require approval of the Company’s shareholders under the applicable requirements of NASDAQ or any national stock exchange on which the Company’s Common Stock is then listed.

In the event of any recapitalization, reorganization, merger, consolidation, spin-off, combination, share exchange, stock split or reverse split, liquidation, dissolution, or other similar corporate transaction or event that affects the Common Stock such that the Committee determines that an adjustment is appropriate in order to prevent dilution or enlargement of Eligible Directors’ rights under the Plan, the Committee may make an adjustment in the number of shares of Common Stock subject to the Plan.

(a) Notwithstanding any other provision of the Plan, the Company shall not be required to issue shares of Common Stock prior to the fulfillment of all of the following conditions:

The Company shall use its best efforts to effect promptly such registrations, listings, qualifications or other approvals and to comply promptly with such laws and regulations.

(e) In the event any provision of the Plan or any action taken pursuant to 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, and the illegal or invalid action shall be deemed null and void.
