"We are very pleased that PGF has obtained RSB certification for carinata," commented Don Konantz, Chief Executive Officer of Calyx. "This is a very significant third-party validation for carinata as a biofuel feedstock that will present significant new opportunities and establish a competitive advantage for this crop."

Mr. Andrew B. Paterson, Chief Executive Officer of PGF, commented, "RSB certification will now allow us to access a number of global markets for carinata oil, which can be converted into renewable aviation fuel or biodiesel. As the airline industry works towards reducing overall greenhouse gas emissions by 20% by the year 2020 it is using the RSB certification as its standard to ensure that procured renewable aviation fuel is produced in an environmentally sustainable manner. PGF Biofuels is continuing to advance development of this industrial oilseed crop, which has strong genetic properties, and is looking forward to scaling up production throughout western Canada and the northern United States."

Mr. Peter Ryus, Chief Executive Officer of RSB Services Foundation, said, "We strongly believe that new industrial oilseeds, such as brassica carinata, are the key to a sustainable bio-based future and we are proud to be a part of the continued development of this unique oilseed."

PGF has partnered with Agrisoma on the commercialization and market development for carinata under the Resonance® brand and is working with Paterson Grain to contract with local growers for production. These efforts will ensure current and future demands for renewable aviation fuel and biodiesel are satisfied. Agrisoma continues to enhance Resonance® carinata with a focus on varietal development, crop protection, product evaluation and agronomic characteristic enhancements.

Additionally, BDC Capital Inc. ("BDC"), also a shareholder of Agrisoma, has advanced $1 million to Agrisoma by way of a promissory note ("Note") to further Agrisoma's business.
