Pacgen Closes Private Placement Financing

Vancouver, BC, Canada (May 28, 2010) – Pacgen Biopharmaceuticals Corporation ("Pacgen" or the "Company") (TSX-V: PGA) announced today that it has closed its previously announced non-brokered private placement (the "Financing") of $600,000 of subscription receipts ("Subscription Receipts"). The Company also announced that it obtained shareholder approval at the special meeting of shareholders held on May 25, 2010 for a consolidation of its common shares (the "Common Shares") on the basis of one post-consolidation Common Share for every two existing Common Shares (the "Consolidation").

Under the Financing, the Company has issued an aggregate of 10,000,000 Subscription Receipts at a price of $0.06 per Subscription Receipt for gross proceeds of $600,000. Upon completion of the Consolidation, each Subscription Receipt will be automatically exercised, for no additional consideration, for one post-consolidation Common Share.

The Company is also pleased to provide an update today in connection with its previously announced financial restructuring (the "Financial Restructuring"). Based on negotiations to date, the Company has reached agreements with its creditors to restructure up to approximately $1.9 million of its indebtedness and financial commitments. Under the terms of these agreements, an aggregate of approximately $879,000 of indebtedness will be converted into an aggregate of 12,618,142 post-consolidation Common Shares (the "Shares for Debt Conversion"). The Shares for Debt Conversion comprises approximately $658,000 of past due debentures being converted into 10,971,485 post-consolidation Common Shares and approximately $57,000 of trade payables being converted into 946,657 post-consolidation Common Shares (each representing an average conversion price of approximately $0.06 per post-consolidation Share) and approximately $221,000 of licensing obligations being converted into 700,000 post-consolidation Common Shares (representing an average conversion price of approximately $0.13 per post-consolidation Share). The Company expects the remaining balance of the restructured indebtedness and financial commitments to be settled by cash discounts, prepaid amounts or future payments linked to performance milestones.

Upon completion of the Consolidation, the Company's 38,144,693 Common Shares currently issued and outstanding will be reduced to approximately 19,072,346 Common Shares. Following the deemed exercise of the Subscription Receipts and completion of the Shares for Debt Conversion, the Company expects to have approximately 41,690,488 post consolidation Common Shares issued and outstanding. Completions of the Consolidation, the Financing, and the Shares for Debt Conversion are subject to the approval of the TSX Venture Exchange.

About Pacgen

Pacgen is a life science technology transfer company focused on the commercial development of novel therapeutic drug candidates up to Phase II, proof of concept efficacy in human. Pacgen sources innovative therapeutic drug candidates globally, and develops these drug candidates in accordance to the United States Food and Drug Administration regulatory standards to feed the product development pipelines of the pharmaceuticals industry. Pacgen’s technology portfolio is composed of 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 human 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.
