or the “Company”) (TSX.V: AWS), is pleased to announce that the Company has entered into a letter of
intent dated June 12, 2018 (the “LOI”) to enter into an arm’s length Share Purchase (the “Transaction”)

About RFT

RFT was incorporated on 2 July 2008 in the Cayman Islands and its main principal is Dr. Carlos Sorentino.

RFT is an innovator in rubber and plastic waste and used tire conversion to energy and graphitic Carbon
Black. RFT’s IP technology uses an eco-friendly proprietary thermolysis continuous process that
depolymerizes rubber waste at low temperature into commercially viable ASTM compliant Carbon Black,
fuel gas, bunker fuel and steel on a continuous basis. The only waste generated is non-toxic and is the
textiles used in the original manufacture of tires, representing about one percent of the original material.
The thermolytic process produces no air emissions.

Graphitic Carbon Black has a wide variety of industrial applications and the newest is in the manufacture
of high grade carbon suitable for lithium battery anodes. The tire industry is the most important user of
Carbon Black as each new tire contains 30% of this material. Other applications are in the manufacture of
high efficiencies anodes for Li-ion batteries, to compound industrial rubber products and plastics,
electronic discharge compounds, high performance coatings and toner and printer inks.

RFT intends to develop, construct and operate plants, based on its proprietary thermolysis
depolymerization technology that enables recycling of used vehicle tires, technical rubber and plastics.
The first commercial plant is expected to have a capacity of 24,000 tonnes and expandable to 48,000
tonnes (532,000 tires).

RFT has established a 500 tonnes a year capacity Pilot Plant in the town of Eisenhüttenstadt, near Berlin,
Germany, where the thermolysis process has been refined over the last twenty years, giving RFT a greater
understanding of the process, product and the market to be a global supplier of continuous tire and waste
conversion facility that meets international standards of excellence. The pilot plant is expected to be
operational four to five months after closing of the Transaction. The pilot plant will produce Carbon Black,
gas, bunker fuel and scrap steel which will be available for commercial sale. The Carbon Black will also be
used for product marketing and the other products will be used to establish marketing channels.

The principal assets of RFT are as follows;

• 50% ownership of land and pilot plant located in Eisenhüttenstadt Germany. The pilot plant
consists of plant building, office equipment, fractional oil distillation column, thermolysis reactor,
magnetic separation, Jet mill, conveyors and hopper/valve system.
• Intellectual property, Patent Co-operation Treaty (“PCT”), patent application process, for the
thermolysis of rubber tires and plastics.
• Processing technology, basic design engineering for 24,000 tonne plant and preparation work for
location at the Evonik Chemical Park located at Marl, Germany and research in a plastics reactor
pilot plant.About the RFT Transaction

Under the terms of the LOI the Company will acquire all the issued and outstanding shares of RFT. The total purchase price for the shares will be US$5,000,000 payable in cash and shares of the Company valued at CAD$0.20 per share as follows:
