(a) At the Effective Time:

(i) each share of common stock, no par value per share, of Acquisition Corp. that shall be outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into one (1) share of common stock, no par value per share, of the Surviving Corporation, so that at the Effective Time, Parent shall be the holder of all of the issued and outstanding shares of the Surviving Corporation;

(ii) the shares of common stock, $0.001 par value per share, of the Company (the "Company Common Stock"), which shares at the Closing will constitute all of the issued and outstanding shares of common stock of the Company, beneficially owned by the Stockholders listed in Schedule 2.4, shall, by virtue of the Merger and without any action on the part of the holders thereof, be converted into the number of shares of Parent Common Stock specified in Schedule 1.5 for each of the Stockholders, which shall be equal to 0.78199 shares of Parent Common Stock for each (1) share of Company Common Stock;

Until the certificate, certificates or affidavit is or are surrendered together with the Letter of Transmittal as contemplated by this Section 1.6 and Section 4 hereof, each certificate or affidavit that immediately prior to the Effective Time represented any outstanding shares of Company Stock shall be deemed at and after the Effective Time to represent only the right to receive upon surrender as aforesaid the Parent Common Stock specified in Schedule 1.5 hereof for the holder thereof or to perfect any rights of appraisal which such holder may have pursuant to the applicable provisions of the DGCL.

Except as set forth in Schedule 1.7, all options, warrants, and other rights of any kind to purchase Company Stock outstanding as of the Effective Date will be exercised or terminated prior to or effective upon the Effective Time, and neither Parent nor Acquisition Corp., except as set forth in Schedule 1.7, shall assume or have any obligation with respect to such options or rights.

1.8 Parent Common Stock. Parent agrees that it will cause the Parent Common Stock into which the Company Common Stock is converted at the Effective Time pursuant to Section 1.5(a)(ii) and 1.5(a)(iii) to be available for such purpose.
