Section 21E of the Securities Exchange Act of 1934, as amended, and "forward-looking information" within the meaning of Canadian securities laws (collectively, "forward-looking statements"). Such forward-looking statements involve known and
unknown risks, uncertainties, and other factors that could cause the actual results of Grace Therapeutics, Inc. (the “Company”) to be materially different from historical results or from any future results expressed or implied by such

"estimates," "potential," "should," "may," "will," "plans," "continue," "targeted" or other similar expressions to be uncertain and forward-looking. Readers are cautioned not to place undue reliance on these forward-looking statements, which
speak only as of the date of this presentation. The forward-looking statements in this presentation, including, but not limited to, statements regarding the Company’s belief that it can address the items cited in the U.S. Food and Drug
Administration’s (“FDA”) Complete Response Letter ("CRL") in a resubmission of its New Drug Application (“NDA”) for GTx-104; the Company's planned approach to addressing the items cited in the CRL following its Type A meeting with the FDA and
receipt of the official meeting minutes; the Company's second-source manufacturing strategy, including remediation at its current contract manufacturer and technology transfer to a second, U.S.-based contract manufacturer; the timing and
outcome of any FDA reinspection of the current contract manufacturer; the Company's plans to complete the required non-clinical studies; and the Company's plans to report progress against key milestones; expected cash runway; the potential
exercise of outstanding warrants; the future prospects of the Company’s GTx-104 drug candidate; GTx-104's potential to bring enhanced treatment options to patients suffering from aneurysmal subarachnoid hemorrhage (“aSAH”); GTx-104’s
potential to be administered to improve the management of hypotension in patients with aSAH; gastrointestinal intolerance and dosing consistency compared with oral administration; the ability of GTx-104 to achieve a pharmacokinetic and safety
profile similar to oral formulations of nimodipine; GTx-104’s potential to provide improved bioavailability and the potential for reduced use of rescue therapies; GTx-104’s potential to achieve medical and pharmacoeconomic benefit over oral
formulations of nimodipine; GTx-104’s commercial prospects; the Company’s pre-commercial launch strategy for GTx104; the future prospects of the Company’s GTx-102 drug candidate; GTx-102’s potential to provide clinical benefits to decrease

potential to be administered to Postherpetic Neuralgia (“PHN”) patients to treat severe nerve pain associated with the disease; the timing and outcomes of a Phase 3 efficacy and safety trial for GTx-101; the size of the addressable market for
GTx-104 and GTx 102, and any future patent and other intellectual property filings made by the Company for new developments, are based upon Grace Therapeutics, Inc.’s current expectations and involve assumptions that may never materialize or
may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, including, without limitation: (i) the
outcome of any Type A meeting with the FDA related to GTx-104; (ii) the timing of any FDA reinspection of the Company’s current contract manufacturer, and that facility’s compliance status, which are determined by the FDA and outside the
Company’s control, and the FDA’s position that it will not approve the NDA while the facility remains in an unacceptable compliance status; (iii) the ability of a second, U.S.-based contract manufacturer to generate the required stability and
analytical data and to complete a product-specific pre-approval inspection; (iv) the need to complete additional non-clinical studies; (v) the requirement that any resubmission comprehensively address all items cited in the CRL and the risk
of review delay; (vi) the Company’s potential need for additional capital, which may not be available on acceptable terms; (vii) the timing and success of any regulatory resubmission of the NDA for GTx-104; (viii) changes to regulatory
requirements or regulatory pathways; (ix) the Company’s ability to protect its intellectual property rights for its product candidates; and (x) legislative, regulatory, political and economic developments. The foregoing list of important
factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are included herein and elsewhere, including the risk factors detailed in the
