(b)

The undersigned may not during any trading day enter into any Transaction (or series of Transactions) that results in a sale of Shares equal to or greater than 10% of total daily volume of the Company’s Common Stock for the trading day; provided, however, that if the daily volume, when compared to the previous trading day’s volume, increases by 35% or more, the Shareholder may sell Shares equal to an additional 5% of that day’s trading volume up to an amount equal to 15% of that day’s daily trading volume.

 

(c)	The undersigned may not enter into a Transaction pursuant to clause 5(b) at a price that is more than 3% above or below the prevailing market price.

(d)

The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a sale or disposition of the Restricted Shares even if such securities would be disposed of by someone other than the undersigned, except to the extent that such sale or disposition is made in compliance with the Dribble Out Provisions.  Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put option or put equivalent position or call option or call equivalent position) with respect to any of the Restricted Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such shares.

Notwithstanding the foregoing, the restrictions set forth in clause (1) and (2) above shall not apply to transfers (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, or (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, 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, or (iii) to extent the undersigned is in compliance with the Dribble Out Provisions set forth in clause 5.  For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In the event that the Company (i) does not apply to list its Common Stock on Nasdaq or NYSE:MKT within 90 days following the date of this Lock-Up Agreement or (ii) its listing application is denied by the Exchange(s) on which the Company has sought to list, then this Lock-Up Agreement shall terminate.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement.  All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.
