Upon any partial exercise of the Warrants evidenced hereby, there shall be signed and issued to the Warrantholder a new Warrant certificate in respect of the Shares as to which the Warrants evidenced hereby shall not have been exercised. These Warrants may be exchanged at the office of the Company by surrender of this Warrant certificate properly endorsed for one or more new Warrants of the same aggregate number of Shares as are evidenced by the Warrant or Warrants exchanged. No fractional shares of Common Stock will be issued upon the exercise of rights to purchase hereunder, but the Company shall pay the cash value of any fraction upon the exercise of one or more Warrants. These Warrants are transferable in the manner and subject to the restrictions set forth or referred to in the Warrant Agreement.

This Warrant Certificate does not entitle the Warrantholder to any of the rights of a stockholder of the Company.
