SCT Announces Agreement with Trillium for Merger

Stem Cell Therapeutics Corp. has announced the execution of a Letter of Agreement with Trillium Therapeutics Inc. of Toronto, under which Trillium would be merged into Stem Cell Therapeutics Corp. by way of a three-cornered amalgamation or plan of arrangement with a newly-created SCT subsidiary.

In addition, SCT announces that its Board of Directors has authorized the implementation of a share consolidation approved by its shareholders at the special meeting held on December 20, 2012 at a ratio of 1 post-consolidation common share for 10 pre-consolidation common shares.

Proposed Merger

Trillium specializes in immunotherapy and cancer stem cell research, with a particular focus on blocking the negative pathways that malignant cells exploit to suppress anti-tumor responses.

Trillium is developing TTI-621, a novel SIRPaFc fusion protein that targets CD47, augmenting the ability of the immune system to destroy cancer stem cells.

The project originated from leading researchers in the field, including Drs. John Dick and Jean Wang of the University Health Network and Dr. Jayne Danska of the Hospital for Sick Children, all of Toronto.

TTI-621, which is expected to enter formal IND-enabling studies in the second quarter of 2013, is being developed initially as a treatment for acute myeloid leukemia (AML), with potential applications in other hematological and solid tumours.

Trillium's preclinical cancer immunotherapy pipeline also includes a fully human CD200-specific monoclonal antibody which is also ready to enter formal IND-enabling studies.

In addition to its preclinical portfolio, Trillium is conducting a clinical trial in patients with interstitial cystitis, a chronic and painful bladder disease. Results from this trial are expected in mid-2013.

"The proposed merger of Trillium and SCT would create Canada's only public company advancing cancer stem cell technologies," said David Allan, the Executive Chairman of SCT.

Allan continued, "With a combined pipeline containing both TTI-621 and the Tigecycline small-molecule program, which SCT recently optioned from the University Health Network, the resulting entity will be well positioned as a global contender in the cancer stem cell field."

It is intended that all Trillium executives and staff will remain with the resulting entity. The current CEO of Trillium, Dr. Niclas Stiernholm, will become the CEO of SCT, Dr. Robert Uger, Chief Scientific Officer, Dr. Penka Petrova, Vice President, Drug Development and Mr. James Parsons, CFO.

Upon closing of the transaction, Dr. Michael Moore, Trillium's long-serving Chairman and veteran biotechnology executive, will join the Board of Directors of SCT.

Following a career at the London Stock Exchange-listed biotechnology company, Xenova Group plc, in 2003 Dr. Moore was appointed Chief Executive Officer of then newly-formed Piramed Limited, which was sold to Roche five years later for $160 million.

As a result of these permanent management appointments the executive services provided by Drs. Albert Agro and Bev Incledon, as an interim measure through their company Concept 2 Clinic Inc., will cease as of closing of the proposed merger.

It is contemplated that the Board of SCT post-merger will consist of Mr. David Allan, Dr. James DeMesa, Dr. Henry Friesen, Mr. Dean Peterson, Dr. Calvin Stiller and Dr. Niclas Stiernholm, all current board members of the Corporation, together with Dr. Michael Moore.

"This transaction will allow the companies' combined assets to gain access to the capital required for their proper development in order to transform them, over time, into valuable new treatments," commented Dr. Stiernholm.

Dr. Stiernholm continued, "My colleagues and I are excited about the upcoming creation of a much needed commercial vehicle for Canada's world class cancer stem cell discoveries. Although a formidable challenge for a company of any size, by building on the strength of our own capabilities, our existing links to several of Ontario's leading cancer research organizations, and our global industry network, we believe we have a real opportunity to make a difference in the future treatment of cancer."

Pursuant to the Letter of Agreement, the security holders of Trillium will receive, on closing of the transaction, an aggregate consideration of $2,850,000. This consideration is comprised of $1.2 million in cash and $1.65 million in SCT common shares, at a deemed price per share not lower than the post-consolidation Discounted Market Price (as per the policies of the TSXV) at the time of this announcement.

SCT and Trillium intend to close the transaction in the first half of 2013, subject to customary closing conditions, including corporate and regulatory approvals, as well as securing the additional financing required to conclude the proposed merger and to advance the SCT development programs.

The latter will be done through a public offering of securities for an amount of $2.5 million to be priced based on market conditions. There can be no assurance that the proposed merger with Trillium will be completed as proposed, or at all.

The proposed merger is an arm's-length transaction and will not result in a change of control of SCT or the creation of a new control person (as defined in TSX-V policies).

All matters of the formation, negotiation and conclusion of the planned merger are being managed by a Special Committee of each of SCT and Trillium.

Dr. Niclas Stiernholm, the CEO of Trillium, is a Director of SCT and in recognition of these relationships, the Trillium Board engaged an independent advisor, reporting directly to Trillium's Special Committee, to explore this proposed merger and other transaction options. The principal security holders of Trillium have indicated they will support the proposed merger.

Common Share Consolidation

The Board of Directors of SCT determined to implement, subject to TSX Venture Exchange approval, a share consolidation of the issued and fully paid common shares without par value of SCT on the basis of 1 post-consolidation common share for 10 pre-consolidation common shares as authorized by SCT's shareholders at the special meeting of shareholders held on December 20, 2012.

No fractional shares shall be issued in connection with the consolidation and any fractional shares resulting from the consolidation will be eliminated.

The number of SCT common shares outstanding is 186,619,359. The number of common shares outstanding following the consolidation will be 18,661,936. There will be no name change in conjunction with the share consolidation.

Letters of transmittal with respect to the consolidation will be mailed out to all registered shareholders. All registered shareholders of SCT will be required to send their certificates representing pre-consolidation common shares with a properly executed letter of transmittal to SCT's transfer agent, Computershare Investor Services Inc., in accordance with the instructions provided in the letter of transmittal.

Shareholders who hold their common shares through a broker or other intermediary and do not have common shares registered in their own name will not be required to complete a letter of transmittal.
