QUÉBEC CITY, Feb. 13, 2013 /CNW Telbec/ - TSO3 Inc. (the "Company"), an innovator in sterilization technology for medical devices in healthcare settings, is pleased to announce today that it has entered into a bought deal agreement with a syndicate of underwriters led by Desjardins Capital Markets (collectively, the "Underwriters"), pursuant to which the Underwriters have agreed to purchase 7,000,000 common shares (the "Common Shares") in the capital of TSO3 at the price of CDN $1.00 per Common Share (the "Issue Price") for aggregate gross proceeds to TSO3 of CDN $7,000,000 (the "Offering"). Under the terms of the agreement, the Company will request an advance income tax ruling from Agence du revenu du Québec confirming that the Common Shares constitute qualifying shares for the Québec Stock Savings Plan II, in accordance with applicable legislation. The Offering is expected to close on or about March 4, 2013 and is subject to customary conditions and regulatory approvals.

The Company has also agreed to grant the Underwriters an over-allotment option (the "Over-Allotment Option"), exercisable for a period of 30 days following the Closing of the Offering, to purchase up to an additional 1,050,000 Common Shares, representing 15% of the Offering, at the Issue Price. If the Over-Allotment Option is exercised in full, the aggregate gross proceeds to TSO3 will be CDN $8,050,000.

As the Company actively pursues US regulatory clearance for the STERIZONE® 125L+ Sterilizer, net proceeds from the Offering will be used to strengthen the Company's financial position in negotiating a channel partner agreement. The proceeds will also allow for continued new product development.
