The Tm Bioscience ID-Tag(TM) Respiratory Viral Panel (RVP)

Tm Bioscience's ID-Tag RVP is a proprietary, comprehensive test for the detection of 20 of the most common strains and subtypes of respiratory viruses, including respiratory syncytial virus A and B, influenza A (with subtyping) and influenza B. The ID-Tag RVP is designed to play a key role in patient management, infection control and in countering the pandemic threat of respiratory diseases.

Tm Bioscience is focused on gaining regulatory clearance from the FDA for ID-Tag RVP as an in vitro device (IVD) in the United States, and is also working towards Health Canada approval and CE marking in Europe. All submissions are currently on track.

In January 2006, Tm Bioscience made the ID-Tag RVP commercially available as an IUO (Investigational Use Only) device. Most recently, the Company has signed distribution agreements for ID-Tag RVP in the Netherlands and in Turkey. Tm anticipates securing additional distribution agreements for the product with the goal of making the test available globally.

In particular, statements about the timing of the anticipated launch of ID-Tag(TM) RVP, its expected role as a cornerstone diagnostic product and as a tool to manage pandemic threats and the expected regulatory status for ID-Tag(TM) RVP in both Europe and the United States, are or involve forward-looking information.

Forward-looking information is based on certain factors and assumptions. In particular, in making the statements in this press release, the Company has assumed that it will receive regulatory approval for the ID-Tag(TM) RVP from the FDA in 2006. The Company has also assumed that ID-Tag(TM) RVP will receive CE marking in Europe coincident with the U.S. FDA approval, that it will be able to develop and manufacture sufficient quantities of its ID-Tag(TM) RVP and that market penetration of ID-Tag(TM) RVP will be such that it will serve a key role in the management and treatment of patients infected by respiratory viruses. While the Company considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect.

Forward-looking information, by its nature necessarily involves risks and uncertainties including, without limitation, the difficulty of predicting regulatory approvals, the timing and conditions precedent to obtaining any regulatory approval, market acceptance and demand for new products, the availability of appropriate genetic content and other materials required for the Company's products, the Company's ability to manufacture its products on a large scale, the protection of intellectual property connected with genetic content, the impact of competitive products, currency fluctuations, risks associated with the Company's manufacturing facility and any other similar or related risks and uncertainties. Additional risks and uncertainties affecting the Company can be found in the Company's 2005 Annual Report, available on SEDAR at www.sedar.com.
