At the effective time of the Merger (the "Effective Time"), each share of the Company's common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions, converted into the right to receive (i) $6.75 per share in cash, without interest, plus (ii) one contingent value right per share (each, a "CVR" and collectively, the "CVRs"), representing the right to receive up to an aggregate of $2.50 in cash per CVR upon achievement, if any, of specified clinical and regulatory milestones, less any applicable tax withholding.
