Biomira Inc. Receives Nasdaq Delisting Notification

EDMONTON, Nov. 5 /PRNewswire-FirstCall/ - Biomira Inc. (the “Company”) today announced that on November 2, 2007, it received a letter from The Nasdaq Stock Market, Inc. (“Nasdaq”) notifying the Company that for the 30 consecutive trading days preceding the date of the letter, the bid price of the Company’s common stock had closed below the $1.00 per share minimum required for continued inclusion on the Nasdaq Global Market pursuant to Nasdaq Marketplace Rule 4450(a)(5). The letter further notified the Company that, in accordance with Nasdaq Marketplace Rule 4450(e)(2), the Company will be provided 180 calendar days, or until April 30, 2008, to regain compliance with the minimum bid price requirement. Compliance will be achieved if the bid price per share of the Company’s common stock closes at $1.00 per share or greater for a minimum of ten (10) consecutive trading days prior to April 30, 2008.

“We expect that we will regain compliance with the minimum bid price rule as one result of the reverse stock split included in the plan of arrangement to be considered at the upcoming special meeting of our shareholders,” said Robert L. Kirkman, M.D. President and CEO of Biomira. “Ensuring compliance with this rule was a major reason the Board of Directors of Biomira included the reverse split in the plan. We also believe that a higher trading price may allow investment in Biomira by institutional investors whose policies preclude investing in stock with lower share prices.”

“The initiatives we have put in place over the last year are each part of a strategic plan to create long-term sustainable value for our shareholders,” continued Dr. Kirkman. “These initiatives include the expansion of our clinical development pipeline with the acquisition of ProlX Pharmaceuticals Inc.; the advancement of Stimuvax(R) into a global Phase 3 trial; the signing of amended and restated collaboration and supply agreements with Merck KGaA, our partner for Stimuvax; and our plan to reincorporate in the United States and revise our capital structure. We are looking forward to the future we believe these steps will make possible, under our planned new name, Oncothyreon Inc.”

The Company has previously announced a special meeting of shareholders to be held at 9:00 a.m. (Mountain Time) in Edmonton, Alberta on December 4, 2007. At the meeting, the Company’s shareholders will consider a special resolution to approve a plan of arrangement under which the Company will migrate to the United States by creating a Delaware holding corporation, Oncothyreon Inc., which will become the ultimate parent corporation of a successor to Biomira and its subsidiaries. If the plan of arrangement is approved by shareholders of Biomira and other conditions are satisfied, including the issuance by the Alberta Court of Queen’s Bench of a final order approving the plan of arrangement, each outstanding common share of Biomira Inc. will be exchanged for one-sixth of a share of common stock of Oncothyreon Inc., which will have the effect of a 6 for 1 reverse stock split of Biomira Inc. common shares.

If compliance with Nasdaq’s Marketplace Rules is not achieved by April 30, 2008, and if the Company is not eligible for an additional compliance period, Nasdaq will provide notice that the Company’s common stock will be delisted from the Nasdaq Global Market. In the event of such notification, the Company would have an opportunity to appeal Nasdaq’s determination or to apply to transfer its common stock to the Nasdaq Capital Market.
