Forward-Looking InformationThis Presentation contains “forward-looking information” within the meaning of applicable Canadian securities legislation which are based upon the Company’s current internal expectations, estimates,projections, assumptions and beliefs and views of future events. Forward-looking information can be identified by the use of forward-looking terminology such as “expect”, “likely”, “may”, “will”, “should”,“intend”, “anticipate”, “potential”, “proposed”, “estimate” and other similar words, including negative and grammatical variations thereof, or statements that certain events or conditions “may”, “would” or “will”happen, or by discussions of strategy. Forward-looking information include estimates, plans, expectations, opinions, forecasts, projections, targets, guidance or other statements that are not statements of fact.

Forward-looking information in this Presentation is based on our opinions, estimates and assumptions in light of our experience and perception of historical trends, current conditions and expected futuredevelopments, as well as other factors that we believe are appropriate and reasonable in the circumstances as at the date hereof. Despite a careful process to prepare and review the forward-looking information,there can be no assurance that the underlying opinions, estimates and assumptions will prove to be correct. In particular, we have made assumptions in respect of the build-out of the Bradford Facility; ourcompetitive advantages; the expected legalization of cannabis use in Canada; the growth of our business and expansion into new markets; the development of new products and product formats for our cannabis-based pharmaceutical products; our ability to retain key personnel; our ability to continue investing in our infrastructure to support our growth; our ability to obtain and maintain financing on acceptable terms; theimpact of competition; the changes and trends in the medical cannabis industry; and changes in laws, rules and regulations.

Forward-looking information is necessarily based on a number of opinions, estimates and assumptions that we considered appropriate and reasonable as of the date hereof, are subject to known and unknownrisks, uncertainties, assumptions and other factors that may cause the actual actions, events, results, performance or achievements to differ materially from what is projected in forward-looking information,including but not limited to the risks described in greater detail in the section entitled “Risk Factors” in our most recent annual information form available on SEDAR at www.sedar.com.

Although we have attempted to identify important factors that could cause actual actions, events, results, performance or achievements to differ materially from those described in forward-looking information,there may be other factors not presently known to us or that we presently believe are not material that may cause actions, events, results, performance or achievements to differ from those anticipated, estimatedor intended. Should one or more of these risks or uncertainties materialize or should assumptions underlying the forward-looking information prove incorrect, actual actions, events, results, performance orachievements may vary materially from those expressed and implied by such statements contained in this Presentation. The purpose of forward-looking information is to provide the reader with a description ofmanagement’s expectations, and such statements may not be appropriate for any other purpose. Accordingly, readers should not place undue reliance on forward-looking information. Although the Companybelieves that the expectations reflected in statements containing forward-looking information are reasonable, it can give no assurance that such expectations will prove to be correct. The Company disclaims anyobligation to update any forward-looking information, whether as a result of new information or future events or results, except to the extent required by applicable securities laws.

Non-IFRS MeasuresThis Presentation refers to certain non-IFRS financial measures including Adjusted Product Contribution Margin, Cash Cost Per Gram Sold and Adjusted EBITDA (i.e., Adjusted Earnings Before Interest, Tax,Depreciation and Amortization). See the section entitled “Non-IFRS Measures” in our Management’s Discussion and Analysis for the year ended March 31, 2017 available on SEDAR at www.sedar.com. Thesemeasures are not recognized measures under IFRS, do not have a standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies.Rather, these measures are provided as additional information to complement those IFRS measures by providing additional information regarding the Company’s results of operations from management’sperspective. Accordingly, non-IFRS measures should not be considered in isolation nor as a substitute for analysis of the Company’s financial information reported under IFRS.
