On April 12, 2013, the Company and ANIP Acquisition Company, a Delaware corporation d/b/a ANI Pharmaceuticals (“ANI”) entered into an amended and restated agreement and plan of merger (the “Merger Agreement”) pursuant to which ANI merged with and into ANI Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (the “Merger Sub”), after which ANI became a wholly owned subsidiary of the Company (the “Merger”).  Pursuant to the terms of the Merger Agreement, at 6:01 p.m. Eastern Time on June 19, 2013 (the “Effective Time”), each outstanding share of capital stock of ANI was converted into the right to receive a number of shares of the Company’s Common Stock, if any, as determined pursuant to the exchange ratio described in the Merger Agreement and the provisions of ANI’s certificate of incorporation, and all options, warrants or other rights to purchase shares of capital stock of ANI, were canceled without consideration therefor, except for certain warrants which were cancelled pursuant to separate agreements.   No fractional shares of the Company’s Common Stock were issued in connection with the Merger, and holders of ANI capital stock were entitled to receive cash in lieu thereof.   MVP II was a holder of capital stock of ANI prior to the Merger and received 16,918,469 shares of Common Stock in the Merger.  The foregoing descriptions of the Merger and the Merger Agreement are intended as a summary only and are qualified in their entirety by reference to the Merger Agreement, which was filed as Exhibit 2.1 to the Company’s current report on Form 8-K on April 12, 2013 and is incorporated by reference herein.

Following the Merger, the stockholders of ANI immediately prior to the Effective Time, which include MVP II, own approximately 57% of the outstanding shares of common stock of BioSante and the stockholders of the Company immediately prior to the Effective Time own approximately 43% of the outstanding shares of common stock of the Company.
