LINCOLNSHIRE, Ill. & BAUDETTE, Minn. -- May 08, 2013

BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX) and ANIP Acquisition Company
d/b/a ANI Pharmaceuticals, Inc. announced today that each company will hold a
special meeting of its stockholders on Wednesday, June 19, 2013 to consider
and vote on certain matters in connection with the proposed merger of a
subsidiary of BioSante into ANI pursuant to the amended and restated agreement
and plan of merger dated April 12, 2013.

BioSante and ANI have fixed the close of business on May 8, 2013 as the record
date for the purpose of determining the stockholders who are entitled to
notice of, and to vote at, their respective special meetings of stockholders.
The special meeting of BioSante stockholders will be held at 8:00 a.m.,
Central Time, at BioSante’s corporate office located at 111 Barclay Boulevard,
Lincolnshire, Illinois 60069. The special meeting of ANI’s stockholders will
be held at 9:00 a.m., Eastern Time, at the offices of MVP Capital Partners
located at 259 N. Radnor-Chester Road, Suite 130, Radnor, Pennsylvania 19087.
BioSante and ANI stockholders are encouraged to read the definitive joint
proxy statement/prospectus in its entirety as it provides, among other things,
a detailed discussion of the proposed merger, the merger agreement and the
process that led to the proposed merger.

The issuance of BioSante shares in connection with the merger will require the
affirmative vote of a majority of the BioSante shares present and entitled to
vote at the BioSante stockholders meeting called to consider such issuance
(assuming a quorum is present). Unvoted shares will not prevent the issuance
of shares in the merger from being approved. The merger also must be approved
by ANI stockholders. In addition to the approval of BioSante and ANI
stockholders, the completion of the merger is subject to other customary
closing conditions.

BioSante stockholders who need assistance in voting their shares or who have
questions regarding BioSante’s special meeting may contact AST Phoenix
Advisors toll-free at (877) 478-5038.

BioSante also announced today that its board of directors has set the close of
business on June 19, 2013, the date of the special meeting of BioSante
stockholders, as the record date with respect to the anticipated distribution
of contingent value rights (CVRs), to holders of BioSante common stock,
providing payment rights arising from a future sale, transfer, license or
similar transaction(s) involving BioSante’s LibiGel^® (female testosterone
gel), including if ANI were to market LibiGel on its own based on BioSante
clinical data with less than $2.5 million further spending in clinical
development and related costs. Although BioSante’s board of directors has set
the record date for such distribution, BioSante’s board of directors has not
authorized yet or declared the distribution and does not intend to do so until
after BioSante stockholders and ANI stockholders have approved the merger and
all related matters being submitted to a vote of such stockholders. The CVR
distribution will be effected immediately prior to, but contingent upon,
completion of the merger.

BioSante and ANI expect to close the merger as soon as practicable following
receipt of approval of the proposals by BioSante stockholders and ANI
stockholders at their respective special meetings.

Under the terms of the merger agreement, if the proposed merger is completed,
a newly formed subsidiary of BioSante will merge with and into ANI, with ANI
continuing as the surviving company and a wholly owned subsidiary of BioSante.
Upon completion of the merger, BioSante will issue to ANI stockholders shares
of BioSante common stock such that the ANI stockholders at the effective time
of the merger will own 57 percent of the combined company’s shares of common
stock outstanding, and the BioSante stockholders at the effective time of the
merger will own 43 percent.

Upon completion of the merger, the combined company will operate under the
leadership of the ANI management team, with Arthur S. Przybyl serving as
president and chief executive officer. In addition to Mr. Przybyl, the board
of directors of the combined company is expected to have two current directors
from BioSante and four current ANI directors.
