2.	As a condition to their willingness to enter into the Merger Agreement, Parent and Merger Sub have requested that Holder, and in order to induce Parent and Merger Sub to enter into the Merger Agreement, Holder has agreed to, enter into this Agreement; and

Subject to the consummation of the Merger and without any further action on the part of Holder, the Warrant, if not theretofore exercised, will be canceled as of the Effective Time in exchange for the right to receive from the Company, as of the Effective Time, cash, without interest, in an amount equal to (a) the product of (i) the number of Shares subject to the Warrants and (ii) the Merger Consideration minus (b) the product of (i) the number of Shares subject to the Warrants and (ii) the per share exercise price of the Warrant immediately prior to the Effective Time, subject to any applicable withholding of Taxes and the terms of the Merger Agreement.
