Pacgen Terminates Letter of Intent with Medigen

Vancouver, BC, Canada (December 29, 2008) – Pacgen Biopharmaceuticals Corporation (“Pacgen” or the “Company”) (TSX-V: PGA) announced today that Pacgen and Medigen Biotechnology Corp. (“Medigen”) have mutually agreed to terminate their letter of intent for a business combination of the two companies.

In accordance with the letter of intent signed in October 2008, the closing of the proposed business combination was subject to certain terms and conditions, including obtaining necessary approvals to enter into a definitive agreement. The parties determined that, in a share for share exchange transaction, the regulatory requirements in Taiwan would require an issuer to redeem dissenting shareholder interests for cash. Both parties anticipate that this requirement would negatively affect the liquidity and capital resources of the combined company, and that the proposed merger would be a significant undertaking given current financial market conditions. As a result, both parties have mutually elected not to proceed with the signing of a definitive agreement.

“We are disappointed that the merger is not completed as planned despite the strong intention of both parties,” said Chung-Yu Wang, Chairman and interim President and CEO of Pacgen. “Pacgen will review all strategic alternatives in light of this development,” added Mr. Wang. “Medigen shares the same disappointment and appreciate the diligence efforts by both teams in the proposed merger,” said Dr. Stanley Chang.

About Pacgen

Pacgen is a life sciences company focused on the development of therapeutics for the treatment of infectious and inflammatory diseases. Pacgen’s current development efforts are focused on PAC-113, an anti-fungal for the treatment of oral candidiasis and PAC-G31P, a novel peptide therapeutic designed to treat inflammatory diseases characterized by non-beneficial neutrophil.

PAC-113 is a 12 amino-acid antimicrobial peptide derived from a naturally occurring histatin protein found in saliva. This peptide alters the permeability of fungal cell membranes causing cell death. In June 2008, Pacgen announced positive results from its Phase IIb clinical trial demonstrating that PAC-113 is effective in the treatment of oral candidiasis and compares favourably to the efficacy demonstrated by Nystatin, a current standard of care. PAC-G31P is a small recombinant protein that is a synthetic analogue of the human cytokine called Interleukin-8 which is the key chemokine involved in neutrophil recruitment. PAC-G31P is currently being investigated in preclinical studies for its potential to treat inflammatory diseases characterized by non-beneficial neutrophil. For additional information, please visit
