('the Company") (OTCBB: BNTNF) ("Bontan") is pleased to announce the official signing and completion of a share exchange agreement with all the shareholders of Portage Pharma Limited ("PPL"), a private Biotech corporation formed under the laws of the British Virgin Islands. Under the terms of the agreement, all the shares of PPL have been exchanged for approximately 81.7 million common shares of Bontan and approximately 71.4 million warrants valid for two years from the date of closing, exercisable to convert into an equal number of common shares of Bontan at an exercisable price of US$0.29 per share. Additionally Bontan issued approximately 9.8 million shares to Culminant Capital Inc., a St. Kitts private corporation, as compensation for financial services rendered to Bontan and PPL in connection with this transaction. All shares and warrants issued will be restricted until registered.

After giving effect to the share exchange transaction, Bontan will have approximately 175 million common shares issued and outstanding of which approximately 91.5 million common shares will be restricted securities. Bontan will also have approximately 140 million options and warrants outstanding which are exercisable into an equal number of common shares.

The transaction resulted in PPL merging into Portage Acquisition Inc., a wholly owned subsidiary of Bontan, incorporated in the BVI. The merged entity will be named Portage Pharma Inc. ("Portage") which will be a subsidiary of Bontan. The senior managers of Portage, Dr. Bruce Littman and Dr. Frank Marcoux, will continue to hold 33,542 options to acquire up to 7% equity in Portage valid for five years at an exercise price of US$1.10 per option. The options vest in agreed instalments over a two year period.

Portage holds an exclusive licence in non-oncology fields under patents granted in the USA, Australia, Israel and New Zealand and patents applied for in Japan and Canada, and an exclusive worldwide licence in non-oncology fields and the know-how relating to the Antennapedia protein (ANTP) transduction technology developed by Trojantec for non-oncology products, treatments or medications.

After completion of the initial share exchange, Mr. Shah will resign as CEO while retaining his role as CFO of Bontan. Dr. Declan Doogan will become the CEO of Bontan.

Mr. Dean Bradley and Mr. Brett Rees will resign as independent directors of Bontan and will be replaced by Dr. Gregory Bailey and Mr. Jim Mellon as independent directors. The new Board will be comprised of Mr. Shah, Dr. Doogan, Dr. Bailey and Mr. Mellon.

PPL currently has nine consultants headed by Dr. Bruce Littman as CEO and Dr. Frank Marcoux, as Chief Scientific Officer. This same team will manage Portage. This team will continue their development of ANTP-containing peptides for non-oncology indications and review other potential opportunities for inclusion in the PPL drug discovery and development portfolio.

The outgoing CEO, Mr. Kam Shah commented, "After a very lengthy period of comprehensive due diligence we are delighted to finalize this exciting transaction with PPL which will look to develop new drugs for the Antennapedia platform. The Company has over US $3.4 million in cash which will meet the initial development costs for the current initiatives at Portage. I am confident that Portage's development team, having over 200 years of combined experience in the financing and the development of new drugs, will position Bontan at the forefront of biotech research and development and should create substantial and sustainable shareholder value."

Dr. Declan Doogan, the incoming CEO commented, "We believe that this merger with Bontan provides our team with access to the capital markets and opportunity to not only to develop ANTP but to look for other compelling drug development opportunities to in-license. I personally am very excited that we have been able to assemble this team of biotech professionals, especially as many of us have worked together on a variety of other successful projects during our professional careers."
