NEW ORLEANS -- April 24, 2013

Former Attorney General of Louisiana, Charles C. Foti, Jr., Esq. and the law
firm of Kahn Swick & Foti, LLC (“KSF”) announce that KSF has commenced an
investigation into the Board of Directors of PROLOR Biotech, Inc. (“PROLOR” or
the “Company) (NYSE MKT: PBTH) in connection with their conduct related to the
sale of the Company to OPKO Health, Inc. (“OPKO) (NYSE: OPK). Under the terms
of the proposed transaction, shareholders of PROLOR will receive 0.9951 shares
of OPKO common stock for each share of PROLOR common stock that they own.
Based on a price of $7.03 per share of OPKO common stock, the transaction is
valued at approximately $480 million, or $7.00 per share of PROLOR common
stock.

KSF’s investigation focuses on whether PROLOR and/or its officers and
directors secured sufficient value for the shareholders of PROLOR, breached
their fiduciary duties, and/or violated state or federal securities laws.
According to Bloomberg reports, the Chairman of PROLOR, who owns approximately
20% of PROLOR’s outstanding stock, is also the Chairman of OPKO, and owns
approximately 39% of OPKO’s outstanding stock as well. Some investors have
expressed opposition to the deal, citing low valuation and the Company’s
announcement of the transaction before the commencement of phase III trials.
