INEX Seeks Approval to Spin-Out Assets Into Tekmira Pharmaceuticals

September 20, 2006 Shareholder Meeting Materials Filed and Mailed


For immediate release: August 23, 2006

Vancouver, BC – Inex Pharmaceuticals Corporation (“INEX”; TSX: IEX) announced today that it has filed with securities regulators in Canada and mailed to shareholders the information circular and proxy materials for the shareholders’ meeting September 20, 2006 at which INEX will seek approval to spin-out the Company’s technology, products, cash and partnerships into Tekmira Pharmaceuticals Corporation (“Tekmira”).

Timothy M. Ruane, President and Chief Executive Officer of INEX, said the spin-out transaction will be the culmination of a number of recent achievements for the Company. “INEX has been very successful over the past number of months including closing the Hana Biosciences, Inc. product development partnership, announcing and then expanding the collaboration with Alnylam Pharmaceuticals, Inc. and eliminating our convertible debt.”

“We are confident that Tekmira will become a company with all the attributes necessary to take INEX’s promising oligonucleotide-based products forward into clinical trials, to work with and benefit from the product development achievements of INEX’s existing partners and to build significant value for shareholders,” Ruane said.

As previously announced, the spin-out of Tekmira will take place by way of a Plan of Arrangement between INEX and its shareholders. Highlights of the spin-out include transferring to Tekmira:

All of the Tekmira shares will be distributed to INEX common shareholders and INEX’s current management team and employees will join Tekmira in the same positions they occupy in INEX.

Completion of this Plan of Arrangement will allow INEX, having no pharmaceutical assets, to complete a financing with an investor group led by Sheldon Reid, a co-founder of Energy Capitol Resources Ltd. (“Investor Group”). The Investor Group will invest up to $5.6 million in INEX by way of convertible debentures. Upon conversion of the debenture following the completion of the reorganization, the Investor Group will hold 100% of non-voting shares in INEX and 80% of the total number of shares outstanding. Therefore, current INEX common shareholders will own 20% of the equity of INEX and 100% of the Tekmira shares. The Investor Group plans to raise additional capital and acquire a new business for INEX. The money received by INEX as part of the corporate reorganization will be paid to the previous holders of INEX’s convertible debt as per the note purchase and settlement agreement announced June 20, 2006.

In addition to shareholder approval, the Tekmira spin-out is subject to regulatory and court approvals. It is also a condition of the spin-out that ongoing litigation with Protiva Biotherapeutics Inc. be transferred from INEX to Tekmira and all claims against INEX be extinguished. The transfer of the litigation to Tekmira is subject to the discretion of the court and INEX believes there is no prejudice to Protiva if the litigation is transferred. Protiva has publicly announced that they intend to oppose the transfer of assets to Tekmira, which would include agreements entered into with Protiva. INEX believes that it has the legal right to transfer the agreements.

The goals for INEX and Tekmira for the second half of 2006 include:
