11.                               Market “Stand-off” Agreement.  The Optionee hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the registration by the Company of its Common Shares or any other equity securities (including, but not limited to, this Optinon) under the Securities Act on a registration statement on Form S-1 (or F-1) or Form S-3 (or F-3), and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days, or such other period, not to exceed seventeen (17) days after the expiration of the 180 day period, as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (1) the publication or other distribution of research reports, and (2) analyst recommendations and opinions, including, but not limited to, the restrictions contained in FINRA Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto), (i) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any option held by Optionee, any Common Shares, or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Shares held immediately before the effective date of the registration statement for such offering or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of any option held by Optionee, any Common Shares, or other securities, in cash, or otherwise.  The foregoing provisions of this Section 11 shall apply only to the intial public offering and shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, or the transfer of any shares to any trust for the direct or indirect benefit of the Optionee or the immediate family of the Optionee, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, and shall be applicable to the Optionee only if all officers and directors are subject to the same restrictions and the Company uses commercially reasonable efforts to obtain a similar agreement from all stockholders individually owning more than one percent (1%) of the Company’s outstanding Common Shares (after giving effect to conversion into Common Shares of all outstanding Preferred Shares).  The underwriters in connection with such registration are intended third-party beneficiaries of this Section 11 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.  The Optionee further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 11 or that are necessary to give further effect thereto.  Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Optionees subject to such agreements, based on the number of shares subject to such agreements. For the avoidance of doubt, this Section 11 shall be of no force or effect upon the execution and delivery by the Optionee of the Joinder to the Company in accordance with Section 10.

12.                               Amendment. The Board may at any time or times amend the Plan or this Agreement for the purpose of satisfying the requirements of any changes in applicable laws or regulations or for any other purpose which at the time may be permitted by law.  No termination, amendment of the Plan or amendment of this Agreement shall, without the Optionee’s consent, materially adversely affect the Optionee’s rights under this Agreement.

13.                               Notices.  All notices, requests, consents and other communications shall be in writing and be deemed given when delivered personally, by telex or facsimile transmission or when received if mailed by first class registered or certified mail, postage prepaid.  Notices to the Company or the Optionee shall be addressed as set forth underneath their signatures below, or to such other address or addresses as may have been furnished by such party in writing to the other.
