Item 5.02.      Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

As previously disclosed, on July 12, 2013, the Board of Directors of BioSante Pharmaceuticals, Inc. (n/k/a ANI Pharmaceuticals, Inc.)(the “Company”) appointed Daniel Raynor to serve as a director of the Company, effective immediately. Mr. Raynor is a co-managing member of Argentum Investments, LLC, the managing member of the general partner of Argentum Capital Partners II, L.P. (“ACP II”), which beneficially holds approximately 5.9% of the Company’s capital stock.

As also previously disclosed, the Board of Directors on July 12, 2013 approved the grant of options to its non-management directors and its executive officers. The grant of options to the Company’s executive officers is subject to approval by the Company’s stockholders of an amendment to the Company’s 2008 Stock Incentive Plan to increase the number of shares authorized for issuance under the Plan. For further information on the above matters, please refer to the Company’s current report on Form 8-K filed on July 16, 2013 (File No. 001-31812), which is incorporated herein by reference.

Item 5.03.              Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On July 17, 2013, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Amendment”) to effect a 1-for-6 reverse stock split of its common stock and class C special stock, a proportional reduction in the number of authorized shares of its common stock, class C special stock and blank check preferred stock, and a change in its name from “BioSante Pharmaceuticals, Inc.” to “ANI Pharmaceuticals, Inc.” The Amendment became effective at 5:01 p.m., EDT, on July 17, 2013.

As disclosed in Item 5.07 of this report, on July 17, 2013, the Company’s stockholders had approved a proposal authorizing the Company’s Board of Directors, in its discretion, to implement a reverse stock split at a ratio of not less than 1-for-4 and not more than 1-for-7 and a corresponding reduction in the number of authorized shares.  Subsequently, on July 17, 2013, the Board of Directors approved the reverse stock split at a ratio of 1-for-6.

At the effective time of the reverse stock split, every six shares of the Company’s pre-split common stock and pre-split class C special stock were automatically combined into one share of common stock or class C special stock, as applicable. No fractional shares are being issued as a result of the reverse stock split, and holders of common stock who otherwise would be entitled to a fractional share will receive, in lieu thereof, a cash payment based on the closing sale price of the Company’s common stock on July 17, 2013.

As a result of the reverse stock split, any options, warrants and rights outstanding as of the effective time that are subject to the reverse split are adjusted consistent with the terms of those options, warrants and rights.

The reverse stock split does not alter the par value of the common stock or class C special stock or modify any voting rights or other terms of the common stock or class C special stock.

The Amendment is filed as Exhibit 3.1 to this report and is incorporated by reference herein. A press release issued by the Company on July 18, 2013 is filed as Exhibit 99.1 to this report and is incorporated by reference herein.

Item 5.07.              Submission of Matters to a Vote of Security Holders.

A Special Meeting of Stockholders of the Company was held on July 17, 2013. The final results of the stockholder votes on each proposal brought before the meeting were as follows:

Each of the proposals was therefore approved by the Company’s stockholders by the required vote.
