TSO3 Simplifies US Regulatory Approach for Faster Clearance – Regulatory Agency Acknowledges and Requests Cleaned Up Filing

Quebec City, December 14, 2012 – TSO3 Inc. (TSX: TOS) (“TSO3” or the “Corporation”) an innovator in sterilization technology for medical devices in healthcare settings, today announced that the Company is simplifying its approach for US regulatory clearance of the STERIZONE® 125L+ Sterilizer, with a single cycle which offers improved claims. The Agency acknowledges the TSO3 approach and requests a cleaned-up and simplified filing for consistency throughout the entire document filed in April 2012.

Last June, the Company received a set of questions based on its April 2012 submission. As previously stated, these questions centered on the chemistry and the detailed mechanism of action that relates to the sterilizer’s performance. The sterilizer’s three preprogrammed cycles using different conditions seemed to complicate the submission.  The Agency agreed with a proposal to simplify the submission by reducing the number of cycles initially available to one from three, while increasing the claims and utility of that one cycle to accommodate all but a few instruments. TSO3has conducted tests to verify the performance resulting from these revised conditions. That information will be incorporated in the new submission.

“This request for a cleaned up and simplified filing was one outcome that was anticipated based on our interactions with the Agency over the last few months and our detailed responses to their questions. As such, efforts to complete such a document began once our response was submitted and we anticipate that this new submission will be ready in late January, or early February”, stated R.M. (Ric) Rumble, CEO of TSO3. “The Company remains focused on this single priority and will continue to allocate the required resources to obtain access to the key market”, he concluded.
