approved the merger of ANI into BioSante, and that BioSante has adjourned its
stockholders meeting until April 12, 2013 to give BioSante stockholders
additional time to vote.

the merger to occur. As of March 15, 2013, 33% of the outstanding shares have
been voted in favor of the merger, which is short of the required majority. Of
those shares that have been voted on the merger, 84% have been voted in favor.

Dr. Louis W. Sullivan, chairman of the board of BioSante stated, “The votes
received to date have been voted overwhelmingly in favor of the merger with
ANI. We believe that most BioSante stockholders recognize the benefits of our
proposed merger with ANI. We are concerned, however, that many of them may not
realize how important their individual votes are to approving the merger. The
board of directors of BioSante unanimously approved this merger and we
continue to believe strongly that it is very much in the best interest of our
stockholders from a financial perspective.”

“In view of the vital importance of the merger to BioSante and its
stockholders, the board of directors of BioSante concluded it was appropriate
to adjourn the meeting and extend the voting period to allow BioSante
stockholders the opportunity to vote,” said Dr. Sullivan, chairman of the
board of BioSante.

Upon completion of the merger, the combined company will be renamed ANI
Pharmaceuticals, Inc. and will operate under the leadership of the ANI
management team, with Arthur S. Przybyl serving as president and chief
executive officer.

“The entire ANI management team strongly believes that by merging with
BioSante we can create value for all stockholders,” said Mr. Przybyl. “The
combined strengths of our two companies will be a powerful accelerant to

common stock and set the close of business on April 12, 2013, the date of the
adjourned special meeting of BioSante stockholders, as the record date with
respect to such distribution. The CVR distribution will be effected
immediately prior to, but contingent upon, completion of the merger.

The special meeting of BioSante stockholders will be reconvened at 8:00 a.m.,
Central Time, on April 12, 2013 at BioSante’s corporate office located at 111

meeting remains January 17, 2013. Stockholders who already have given a proxy
or instructions to brokers do not need to re-cast their votes.

If the BioSante stockholders approve the merger, it is expected that the
merger will close as soon as practicable thereafter.

BioSante stockholders are reminded that their vote is important. A failure to
vote has the same effect as a vote against the adoption of the merger
agreement. Any BioSante stockholder who has not yet voted is urged to vote FOR
the adoption of the merger agreement and the transactions contemplated
thereby, as well as the other merger related proposals. BioSante stockholders
