2 Forward Looking Statements All statements in this presentation that are other than statements of historical facts are forward-looking statements which contain our current expectations about our future results. Forward-looking statements involve numerous risks and uncertainties. We have attempted to identify any forward-looking statements by using words such as anticipates, believes, could, expects, intends, may, should and other similar expressions. Although we believe that the expectations reflected in all of our forward-looking statements are reasonable, we can give no assurance that such expectations will prove to be correct. A number of factors may affect our future results and may cause those results to differ materially from those indicated in any forward-looking statements made by us or on our behalf. Such factors include our early stage of technology development; our need for capital to finance necessary research and product development; our ability to attract and retain key employees and strategic partners; our ability to achieve and maintain profitability; fluctuations in the trading price and volume of our stock; competition from other providers of similar products and services; and other unanticipated future events and conditions. For further information concerning risks and uncertainties that may affect our future results, please review the disclosures as may be contained from time to time in our filings with SEDAR. Other than as required by applicable securities laws, we undertake no obligation to publicly update or revise any of our forward-looking statements, whether as a result of changed circumstances, new information, future events, or for any other reason occurring after the date of this presentation. This presentation does not constitute an offer to sell or solicitation of an offer to buy securities in any jurisdiction. 2

3 Amine Carbon Capture Challenges High costs High operating costs from using high grade steam $60-90/tonne of CO 2 for flue gas application (1,2) ; significantly more than present or planned carbon pricing Environmental and operational problems (3) Toxic waste products Unstable solvents Use of amines not realistic for widespread, large-scale CCUS 3 Sources: 1) Page 19 (~$70/tonne cost) 2) Page 6 3)

4 Enzyme-enabledCO2 capture Carbonic Anhydrase (CA) enzyme Extreme conditions (P, T, Salinity) Directionally evolved to be sturdier in industrial conditions Stable in process conditions Active metallic site Catalyses CO 2 hydration reactions + + Enzyme is mass produced Active metallic site 4

5 Chemical reactions (gas) Gas/Liquid interface (aqueous) Carbonic Anhydrase KHCO 3 Carbonate Bicarbonate 5

6 Our Process An IndustrialLung NON-TOXIC CARBONATE SALT SOLVENT Flue Gas less CO 2 STANDARD GAS TREATMENT EQUIPMENT Pure CO 2 (>99%) for Reuse and/or Sequestration CO 2 Absorber Column CO 2 Stripper Column Flue Gas with CO 2 USES LOW-GRADE HEAT (~80ᵒC) FOR REGENERATION ENERGY 6 Enzyme catalyses CO 2 capture with low levels of energy, in a benign and stable non-chemical absorbing solution

7 Scale-Up Progress <2014 Lab and Bench-Scale: 0.5 tpd Pilot: 1 tpd 2015 Demonstration: 10 tpd tpd = metric tonnes CO 2 captured per day Now Commercial

8 10 t/d Demonstration -Results 8 Operated 2500 hours CO 2 produced is at 99.95%+ purity Confirmed absorbing solution system performance No toxic waste products generated Entire solution volume was sent to municipal sewer at end of campaign without requiring treatment Easy automated operation

9 Large Scale Application Performance data from demo upscaledby TetratechInc. for larger scale costing Base case Full-size once-through steam generator (OTSG); Natural gas combustion 1250 tonnes CO 2 /day captured Cost of capture (CO 2 produced at 2 bara and before Return on Capital) ($/tco 2 ) Fixed Costs 6.9 Variable costs 12.6 Total Capital Req. (30 year amort.) 8.5 Total $28.0 9

10 Value Propositions More than 50%+ cost savings vs. conventional amine CO 2 capture technology No toxic wastes or aerosols Process produces high purity CO 2 for broad range of applications 10

11 Alberta Project 11 $15 million from Emissions Reduction Alberta (ERA) towards $30M commercial scale deployment of CO 2 Solutions process in Alberta Up to 300 tonnes-co 2 /day Open to other funding sources DBOM or Licence option Seeking consortium partners

12 Valorisation Carbone Québec project To demonstrate high-potential upgrading schemes At a petrochemical facility in Montreal-East In next 2 years Coupled with CO 2 Solutions capture technology Led by CO 2 Solutions in partnership with Laval University Reviewing >70 potential processes for demo Particular interest in processes that can use renewable/hydro electricity Aligned with participation in NRG COSIA Carbon XPRIZE 12
