Pursuant to a securities exchange agreement dated February 8, 2021 among the Company, TTI-US and the securityholders of TTI-US (the "Securities Exchange Agreement"), as amended, the Company has acquired all of the outstanding securities of TTI-US resulting in TTI-US becoming a wholly-owned subsidiary of the Company. As consideration for the acquisition of TTI-US, the Company issued an aggregate of 12,771,075 common shares and 1,000,000 common share purchase warrants exercisable at $0.50 per shares for a term of 2 years upon issuance.

There are now 27,910,175 TTI common shares issued and outstanding. Former TTI-US securityholders collectively hold approximately 45.76% of the shares on a non-diluted basis, the Company's existing shareholders hold approximately 18.41% of the shares, and participants in the Concurrent Financing of Special Warrants (see below) hold approximately 35.83% of the shares.

Final acceptance of the QT will occur upon the issuance of the Final Exchange Bulletin (the "Exchange Bulletin") by the Exchange. Subject to final acceptance by the Exchange, TTI will be classified as a Tier 2 Life Sciences issuer pursuant to Exchange policies.

Immediately prior to closing of the QT, the Company converted 10,000,000 previously issued special warrants (see the Company's press release dated August 4, 2021) into 10,000,000 TTI common shares. This financing raised gross proceeds of $3,500,000 through the issuance of 10,000,000 special warrants at a price of $0.35 per special warrant, each special warrant being convertible, without further consideration, into one common share of TTI.
