("Tetra" or the "Company") (TSX VENTURE:TBP)(OTCQB:TBPMF), a global leader in cannabinoid-based drug development, is pleased to announce that Tetra opened the Toronto Stock Exchange ("TSX") yesterday at a ceremony to recognize the listing and trading of Tetra, which began on August 16^th 2017 under the symbol TBP. The listing ceremony took place at the TMX Broadcast Centre in Toronto, Ontario. Bernard Fortier, Chief Executive Officer (CEO), and Bernard Lessard, Chief Financial Officer, represented Tetra at the listing ceremony.

"Being listed on the TSX Venture Exchange helps us access the capital and liquidity we require to execute our strategies and drive our future success. We are very proud to have been invited for the opening ceremony. This is a great occasion for us to generate exposure for our company." stated Bernard Fortier, CEO.

The TSX Venture Exchange is a public venture capital marketplace for emerging companies.

Indeed, Tetra announced last week the accelerate submission of new drug application to FDA and expectation to commercialize Dronabinol XL tablet (PPP002) ahead of schedule in the US. Tetra is also on the verge of starting its phase 3 clinical trial for PPP001, first smokable drug for advanced cancer pain.

CLARIFICATION: Tetra Bio-Pharma Inc.

In the news release, Tetra Bio-Pharma accelerates submission of New Drug Application to FDA & Expects to Commercialize Dronabinol XL Tablet Ahead of Schedule in the US, issued on November 28^th, 2017 by Tetra Bio-Pharma Inc. over Marketwired, The Company, at the request of IIROC, would like to provide additional precision and clarification to what was described in the second paragraph regarding the potential in revenue generated after its third year post Adversa® launch. This paragraph should read: Based on the expected improved safety profile of a delayed release Dronabinol, as well as the required investment in supporting sales and marketing efforts, Tetra expects the Adversa® tablet to gain a share of the chemotherapy-induced nausea and vomiting market after its launch in the USA. The current market for CINV in the USA is $150,000,000, based on dronabinol sales (IMS data 2016). No sales of Adversa® are expected within the next 12 months as Tetra will be in the process of conducting the necessary pharmacokinetic study, as well as gathering the necessary information for a manufacturing file, both of which will be part of the basis for the Tetra's planned 505(b)(2) new drug application and potential NDA submission in 2019. Tetra is retracting its projection on the potential of revenue of up to $30 million USD as it cannot be relied upon at this point in time.
