6.         Exercise.



(a)        This Retention Option shall be exercised, as to the vested shares, by delivery to the Company of (a) written notice of exercise stating the number of Shares being purchased (in whole shares only) and such other information set forth on the form of Notice of Exercise attached hereto as Exhibit A hereto, (b) a check or cash in the amount of the Exercise Price of the Shares covered by the notice, unless Recipient elects to exercise the cashless exercise option set forth inSection 6(b)below, in which case no payment will be required (or such other consideration as has been approved by the Board of Directors consistent with the Plan) and (c) a written investment representation as provided for inSection 13hereof. This Retention Option shall not be assignable or transferable, except by will or by the laws of descent and distribution, and shall be exercisable only by Recipient during his or her lifetime.



---



(b)Anything herein to the contrary notwithstanding, to the extent vested the Retention Option may also be exercised at such time by means of a cashless exercise in which the Recipient shall be entitled to receive a certificate for the number of Shares equal to the quotient obtained by dividing[(A-B) (X)] by (A), where:



(A) equals the average of the closing price of the Companys Common Stock, as reported (in order of priority) on the OTC Bulletin Board; or  if the Common Stock is not then quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the Pink Sheets published by Pink Sheets, LLC (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holder and the Company, the fees and expenses of which shall be paid by the Company for the three (3) Trading Days immediately preceding the date of such election;



(B) equals the Exercise Price of the Retention Option, as adjusted; and



(X) equals the number of Shares issuable upon exercise of this Retention Option in accordance with the terms of this Retention Option by means of a cash exercise rather than a cashless exercise (or, if the Retention Option is being exercised only as to a portion of the shares as to which it has vested, the portion of the Retention Options being  exercised at the time the cashless exercise is made  pursuant to thisSection 6).



For purposes of this calculation:



Trading Day means a day on which the Common Stock is traded on a Trading Market.



Trading Market means the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the American Stock Exchange, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange or the OTC Bulletin Board.



(c)No fractional shares shall be issued upon exercise of this Retention Option.  The Company shall, in lieu of issuing any fractional share, pay the Recipient entitled a sum in cash equal to such fraction multiplied by the then effective Exercise Price.



7.         Termination of Service.



(a)    If the Employment Agreement is terminated by the Recipient prior to March 31, 2011 effective as of the date of such termination (the Recipient Termination Date), no further installments of the Retention Option shall vest pursuant toSection 5, and the maximum number of Shares that Recipient may purchase pursuant hereto shall be limited to the number of Shares that were vested as of the Termination Date. Thereupon, Recipient shall have the right at any time within 120 days of the Termination Date the then remaining exercise period of such vested options to exercise this Retention Option to the extent vested and purchase Shares, to the extent, but only to the extent, that Recipient could have exercised this Retention Option as of the

---



Recipient Termination Date; following the expiration of the remaining option period this Agreement shall terminate in its entirety and be of no further force or effect.



(b)    If the Employment Agreement is terminated by the Company prior to March 31, 2011 (the Company Termination Date) then the Retention Option shall vest in full, effective as of the date of the Company Termination Date.  Thereupon, Recipient shall have the right at any time within the then remaining exercise period of such vested options to exercise this Retention Option.  Following the expiration of the remaining option period this Agreement shall terminate in its entirety and be of no further force or effect.



8.       Death of Recipient.



If the Recipient shall die during the term of the Employment Agreement, Recipients personal representative or the person entitled to Recipients rights hereunder may at any time within the then remaining exercise period, exercise this Retention Option and purchase Shares to the extent, but only to the extent, that Recipient could have exercised this Retention Option as of the date of Recipients death; following the expiration of the aforesaid then remaining exercise period, this Agreement shall terminate in its entirety and be of no further force or effect.





9.         No Rights as Shareholder.

(iii)       In the event of a change in the shares of the Company as presently constituted, which is limited to a change of all of its authorized Stock without par value into the same number of shares of Stock with a par value, the shares resulting from any such change shall be deemed to be the Shares within the meaning of this Retention Option.



(iv)       To the extent that the foregoing adjustments relate to shares or securities of the Company, such adjustments shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as hereinbefore expressly provided, Recipient shall have no rights by reason of any subdivision or consolidation of shares of Stock of any class or the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class, and the number and price of Shares subject to this Retention Option shall not be affected by, and no adjustments shall be made by reason of, any dissolution, liquidation, merger, consolidation or sale of assets or capital stock, or any issue by the Company of shares of stock of any class or securities convertible into shares of stock of any class.



(v)        The grant of this Retention Option shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes in its capital or business structure or to merge, consolidate, dissolve or liquidate or to sell or transfer all or any part of its business or assets.
