VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 8, 2012) - Calyx Bio-Ventures Inc. ("Calyx" or the "Company") (TSX VENTURE:CYX) is pleased to provide its shareholders with a corporate update.

Background

Calyx owns proprietary technology that allows for the rapid enhancement of gene traits in plants, known as Engineered Trait Loci ("ETL") chromosome engineering. Calyx has licensed this technology exclusively to Agrisoma Biosciences Inc. ("Agrisoma"), one of Canada's largest agro-science companies. Calyx holds an approximately 32% interest (fully diluted) in Agrisoma, including shares that would be issued on the conversion of approximately $2.4 million of convertible debt of Agrisoma held by Calyx and due in June 2012. As Calyx's proprietary technology has been licensed exclusively to Agrisoma and as Calyx owns a significant interest in Agrisoma, the business of Agrisoma is also the primary business of Calyx.

Agrisoma sells seeds to farmers, and has an exclusive position with regard to commercial carinata seed (Brassica Carinata), a member of the mustard family and a relative of canola. Carinata is an oilseed crop which produces oil that is ideal for industrial applications such as biojet fuel, biodiesel, and emulsifiers. Commercial carinata seed is being sold under the Resonance™ brand name and is the result of more than a decade of development efforts and advanced crop improvement efforts. Agrisoma is now commercializing this oilseed as a sustainable source of feedstock for the production of biofuel. Agrisoma is further continuing the development of carinata varieties which incorporate ETL technology to improve oil yields and quality. Agrisoma's key markets for the Resonance™ brand carinata include western Canada, the northern plain states and the southeast United States.

Recent Developments

On January 3, 2012, Calyx announced that it completed a non-brokered private placement of 3,428,333 common shares at an offering price of $0.15 per share for gross proceeds of $514,250.

On April 3, 2012, Agrisoma and Paterson Grain announced a long term partnership agreement for the commercial contracting and distribution of carinata under the brand name Resonance™, a name that reflects carinata's energy connection.

On April 17, 2012, biojet fuel refined from carinata developed by Agrisoma was blended with a commercial jet fuel. The resulting fuel product was used for Canada's first ever biojet fuel-powered revenue flight. Porter Airlines flew one of its Bombardier Q400 turboprops from its base at Billy Bishop Toronto City Airport to Ottawa using a 50/50 blend of biofuel and Jet A1 fuel in one of its engines.

On April 18, 2012, Agrisoma unveiled the first comprehensive flight program in the world to use biojet fuel produced from Resonance™ brand carinata. The program will evaluate Honeywell Green Jet Fuel™, which is refined from Resonance™ feedstock. The flight program is being conducted in partnership with the National Research Council in Ottawa with funding from the Government of Canada's Clean Transportation Initiatives.

Future Plans

Management of Calyx and Agrisoma are continuing to work toward full-scale commercialization of carinata. For the duration of the current year, Calyx proposes to work with Agrisoma to achieve additional strategic partnerships, continue biojet fuel production with multiple manufacturers, further test biojet fuel refined from carinata in multiple environments, and continue field trials of strains of carinata incorporating ETL technology. Subject to its own financial position, Calyx proposes to continue to fund its interest in Agrisoma.

While the above statement reflects Calyx's current views with respect to future events, such views are subject to certain risks, uncertainties and assumptions. Many factors could cause actual results, performance or achievements to be materially different from any anticipated future plans that may be expressed or implied. The Company does not intend, and does not assume any obligation, to update any such factors or to publicly announce the result of any revisions to any of the forward-looking statements contained herein to reflect future results, events or developments except as required by law.
