PROSPECTUS SUPPLEMENT
(to the Short Form Base Shelf Prospectus dated October 6, 2023)

NEW ISSUE March 27, 2024

ORGANIGRAM HOLDINGS INC.

$25,000,200

7,740,000 UNITS

This prospectus supplement (the “Prospectus Supplement”), together with the short form base shelf prospectus to which it relates dated October 6, 2023, as amended or supplemented (the “Prospectus”), qualifies the distribution (the “Offering”) of 7,740,000 units (the “Units”) of Organigram Holdings Inc. (the “Corporation”) at a price of $3.23 per Unit (the “Offering Price”). Each Unit will consist of one common share of the Corporation (a “Unit Share”) and one-half of one common share purchase warrant of the Corporation (each full warrant, a “Warrant”). Each Warrant will entitle the holder thereof to acquire one Common Share (as defined herein) (each, a “Warrant Share”) at an exercise price of $3.65 per Warrant Share, until 5:00 pm (Eastern Time) on the date that is four years following the Closing Date (as defined herein). The Warrants will be governed by a warrant indenture (the “Warrant Indenture”) to be entered into on the Closing Date between the Corporation and TSX Trust Company, as warrant agent (the “Warrant Agent”). The Units will not trade and will separate into Unit Shares and Warrants immediately upon issuance. This Prospectus Supplement also registers the issuances of the Warrant Shares.

The Units are being offered pursuant to an underwriting agreement dated March 27, 2024 (the "Underwriting Agreement") among the Corporation, ATB Securities Inc. (the "Lead Underwriter"), as lead underwriter, for and on behalf of a syndicate of underwriters that also includes A.G.P. Canada Investments ULC (collectively with the Lead Underwriter, the "Underwriters"). The Units will be offered in all of the provinces and territories of Canada, except Québec, and the United States directly and through the Underwriters' broker-dealer affiliates or agents. See "Plan of Distribution".

The Corporation's issued and outstanding common shares (the "Common Shares") are listed on the Toronto Stock Exchange (the "TSX") and the Nasdaq Global Select Market (the "NASDAQ") under the symbol "OGI". On March 26, 2024, the last trading day prior to the date of announcement of the Offering, the closing prices of the Common Shares on such exchanges were $3.65 and US2.68, respectively.

The Corporation has applied to list the Unit Shares and the Warrant Shares on the TSX and has notified NASDAQ of the Offering. Listing is subject to the approval of the TSX and completion of NASDAQ's review process in accordance with their respective applicable listing requirements and will be subject to the Corporation fulfilling all of the listing requirements of the TSX and the NASDAQ. The Corporation does not intend to apply to list the Warrants on the TSX, NASDAQ, or any other securities exchange or other trading system. There is currently no market through which the Warrants may be sold and purchasers may not be able to resell Warrants purchased under this Prospectus Supplement. This may affect the pricing of the Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of the Warrants and the extent of issuer regulation. See "Risk Factors".

The Units and the Warrant Shares issuable upon exercise of the Warrants offered by this Prospectus Supplement will also be registered in the United States under the terms of a registration statement on Form F-10 (File No. 333-274686) (the "Registration Statement") filed with the United States Securities and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended (the "U.S. Securities Act").

Offering Price: $3.23 per Unit

	Price to the Public(1)	Underwriters' Fee(2)	Net Proceeds to the Corporation(3)
Per Unit	$3.23	$0.1534	$3.0766
Total(4)	$25,000,200	$1,187,509.50	$23,812,690.50

(1)The Offering Price was determined by arm's length negotiation between the Corporation and the Underwriters, with reference to the prevailing market price of the Common Shares.

(2)The Corporation has agreed to pay the Underwriters a cash fee (the "Underwriters' Fee") equal to 4.75% of the gross proceeds from the Offering (including any gross proceeds resulting from the exercise of the Over-Allotment Option (as defined below)). See "Plan of Distribution" for additional information regarding the Underwriters' Fee.

(3)After deducting the Underwriters' Fee but before deducting the expenses of the Offering (estimated to be approximately $465,000 which does not include legal fees of US counsel to the Underwriters) which will be paid from the proceeds of the Offering.

(4)The Corporation has granted the Underwriters an over-allotment option, exercisable in whole or in part, at the sole discretion of the Lead Underwriter, at any time, and from time to time, for a period of 30 days from the closing date (the “Closing Date”) to purchase up to an additional 15% of the Offering, which may be comprised of the acquisition of: additional Units (the “Over-Allotment Units”) at the Offering Price to cover over-allotment, if any, and for market stabilization purposes (the “Over-Allotment Option”). If the Over-Allotment Option is exercised in full, the total “Price to the Public”, “Underwriters’ Fee” and “Net Proceeds to the Corporation” will be $28,750,230, $1,365,635.92 and $27,384,594.08, respectively. This Prospectus Supplement, together with the Prospectus, qualifies the grant of the Over-Allotment Option. A purchaser who acquires additional Unit Shares (the “Additional Shares”) or additional Warrants (the “Additional Warrants” and together with the Additional Shares, the “Additional Securities”) issuable on the exercise of the Over-Allotment Option acquires such Additional Securities under this Prospectus Supplement regardless of whether the over-allotment position is ultimately filled through the exercise of the Over-Allotment Option or secondary market purchases. See “Plan of Distribution”.

The following table sets out information relating to the Over-Allotment Option:

Underwriters' Position	Maximum Size or Number of Additional Securities Available	Exercise Period	Exercise Price
Over-Allotment Option	1,161,000 Over-Allotment Units	30 days from the Closing Date	$3.23 per Over-Allotment Unit

Unless the context otherwise requires, when used herein, all references to the "Offering", "Units", "Unit Shares" and "Warrants" include the Over-Allotment Units, Additional Shares and Additional Warrants issuable upon exercise of the Over-Allotment Option.

Any investment in the Units involves significant risks that should be carefully considered by prospective investors before purchasing the Units. The risks outlined in this Prospectus Supplement, the Prospectus, and in the documents incorporated by reference herein and therein, should be carefully reviewed and considered by prospective investors in connection with any investment in the Units. See the "Risk Factors" section of this Prospectus Supplement and the Prospectus.

The Underwriters, as principals, conditionally offer the Units for sale, subject to prior sale, if as and when issued, and accepted by the Underwriters, in accordance with the terms and conditions contained in the Underwriting Agreement described under "Plan of Distribution" and subject to the approval of certain legal matters on behalf of the Corporation by Goodmans LLP, by McMillan LLP, with respect to U.S. legal matters and Hodgson Russ LLP, with respect to certain U.S. federal income tax matters, and on behalf of the Underwriters, by Dentons Canada LLP, with respect to Canadian legal matters.

Subscriptions for the Units offered hereunder will be received subject to rejection or allotment, in whole or in part, and the Underwriters reserve the right to close the subscription books at any time without notice. Closing of the Offering (the "Closing") is expected to take place on or about April 2, 2024, or such other date as may be agreed upon by the Corporation and the Underwriters, provided that the Units are to be taken up by the Underwriters on or before the date that is not later than 42 days after the date of this Prospectus Supplement. See "Plan of Distribution".

2

In connection with the Offering, subject to applicable laws, the Underwriters may over-allot or effect transactions that are intended to stabilize or maintain the market price of the Common Shares at levels other than those which otherwise might prevail on the open market. Such transactions, if commenced, may be discontinued at any time. See "Plan of Distribution".

The Unit Shares and Warrants comprising the Units will be deposited on the Closing Date with CDS Clearing and Depository Services Inc. ("CDS") or its nominee, or The Depository Trust Corporation ("DTC") or its nominee, in either case, in electronic form, except in certain limited circumstances. A purchaser of Units will receive only a customer confirmation from the Underwriter or registered dealer from or through whom the Units are purchased and who is a CDS or DTC depository service participant. See "Plan of Distribution".

The Corporation is permitted, under a multi-jurisdictional disclosure system (the "MJDS") adopted by the securities regulatory authorities in Canada and the United States, to prepare the Prospectus and this Prospectus Supplement in accordance with Canadian disclosure requirements, which are different from those of the United States. Financial statements incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and may not be comparable to financial statements of United States companies. The Corporation's financial statements are subject to audit in accordance with the standards of the Public Corporation Accounting Oversight Board (United States) ("PCAOB") and its auditor is subject to both Canadian auditor independence standards and the auditor independence standards of the PCAOB and the SEC.

The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely because the Corporation is a corporation existing under the laws of Canada. The Corporation exists under the laws of Canada, and all of its executive offices, administrative activities and assets are located outside the United States. In addition, all of the directors and officers of the Corporation are residents of jurisdictions other than the United States and all or a substantial portion of the assets of those persons are or may be located outside the United States. See the "Enforceability of Civil Liabilities by U.S. Investors" section of this Prospectus Supplement.

THE UNITS, THE UNDERLYING UNIT SHARES AND WARRANTS, THE WARRANT SHARES ISSUABLE UPON EXERCISE OF THE WARRANTS, HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY NOR HAS THE SEC OR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS SUPPLEMENT OR THE PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

You should be aware that the acquisition of the securities described herein may have tax consequences both in the United States and in Canada. Such consequences may not be described fully in this Prospectus Supplement or the Prospectus. Investors should read the tax discussion in this Prospectus Supplement and consult their own tax advisors with respect to their particular circumstances. See "Certain Canadian Federal Income Tax Considerations", "Certain U.S. Federal Income Tax Considerations" and "Risk Factors".

Simon Ashton, Director of the Corporation, Karina Gehring, Director of the Corporation, and Marni Wieshofer, Director of the Corporation (collectively, “Non-Resident Persons”), have appointed the Corporation, 145 King Street West, Suite 1400, Toronto, Ontario, Canada, M5H 1J8, as agent for service of process. Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person that resides outside of Canada, even if the party has appointed an agent for service of process.

The Corporation is continued under the Canada Business Corporations Act and its head and registered office is located at 145 King Street West, Suite 1400, Toronto, Ontario, Canada, M5H 1J8.

IMPORTANT INFORMATION ABOUT THE PROSPECTUS
AND THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this Prospectus Supplement, which describes the specific terms of the Offering and also adds to and updates certain information contained in the Prospectus and the documents incorporated by reference herein and therein. The second part is the Prospectus, which gives more general information, some of which may not apply to the Offering. This Prospectus Supplement is deemed to be incorporated by reference in the Prospectus solely for the purpose of the Offering.

If the description of the Units, Unit Shares, Warrants or Warrant Shares varies between this Prospectus Supplement and the Prospectus, you should rely on the information in this Prospectus Supplement.

No representation is made in respect of information that is not included in, or specifically incorporated by reference into, the Prospectus. We have not authorized anyone to provide you with different or additional information. The information contained in this Prospectus Supplement, the Prospectus and the documents incorporated by reference herein and therein is accurate only as of the respective dates of those documents, and you should not assume otherwise.

We are not making an offer of Units in any jurisdiction where the offer is not permitted by law.

The Prospectus also forms part of the Registration Statement that we filed with the SEC under the U.S. Securities Act utilizing the MJDS. The Registration Statement was declared effective by the SEC under the U.S. Securities Act on November 29, 2023 (SEC File No. 333-274686). This Prospectus Supplement is being filed by us with the SEC pursuant to General Instruction II.L of Form F-10. The Registration Statement incorporates the Prospectus and the Prospectus Supplement with certain modifications and deletions permitted by Form F-10.

Unless the context otherwise permits, indicates or requires, all references in this Prospectus Supplement to the "Corporation", "we", "our", "us" and similar expressions are references to Organigram Holdings Inc. and the business carried on by it.

MARKETING MATERIALS

Any "template" version of any "marketing materials" (as such terms are defined under applicable Canadian securities laws) that has been prepared in connection with the Offering is not part of this Prospectus Supplement and the Prospectus to the extent that the contents of the template version of the marketing materials have been modified or superseded by a statement contained in this Prospectus Supplement or the Prospectus. Any template version of any marketing materials that has been, or will be, filed on SEDAR+ (www.sedarplus.ca) or with the SEC (www.sec.gov) in connection with the Offering after the date of this Prospectus Supplement and before the termination of the distribution under the Offering (including any amendments to, or an amended version of, any template version of any marketing materials) is deemed to be incorporated by reference into this Prospectus Supplement and the Prospectus solely for the purposes of the Offering.

NOTE TO U.S. READERS REGARDING DIFFERENCES BETWEEN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Corporation prepares its financial statements in accordance with IFRS, as issued by the IASB, which differ from U.S. generally accepted accounting principles ("U.S. GAAP"). Accordingly, the Corporation's financial statements incorporated by references in the Prospectus Supplement, and in the documents incorporated by reference in this Prospectus Supplement, may not be comparable to financial statements of United States companies prepared in accordance with U.S. GAAP.

CURRENCY PRESENTATION AND EXCHANGE RATE INFORMATION

Unless otherwise noted herein and in the documents incorporated by reference, all dollar amounts refer to lawful currency of Canada. All references to "US$" or "U.S. dollars" are to the currency of the United States.

S-1

The following table sets forth, for the periods indicated, the high, low, average and period-end indicative rates of exchange for one U.S. dollar expressed in Canadian dollars, each based on the daily average rate of exchange published by the Bank of Canada for conversion of U.S. dollars into Canadian dollars.

	Fiscal Year Ended		Three Months Ended
	September 30, 20231	August 31, 2022	December 31, 2023	November 30, 2022
Low	1.2980	1.2329	1.3205	1.2980
High	1.3856	1.3138	1.3875	1.3856
Average	1.3474	1.2720	1.3622	1.3488
End	1.3520	1.3111	1.3226	1.3508

On March 26, 2024, the daily average rate of exchange posted by the Bank of Canada for conversion of U.S. dollars into Canadian dollars was US$1.00 = $ 1.3572. We make no representation that U.S. dollars could be converted into Canadian dollars at that rate or any other rate.

FORWARD-LOOKING STATEMENTS

This Prospectus Supplement and the Prospectus, including the documents incorporated by reference herein and therein, contain "forward-looking statements" or "forward-looking information" within the meaning of applicable securities legislation (collectively referred to herein as "forward-looking information" or "forward-looking statements") which are based upon the Corporation's current internal expectations, estimates, projections, assumptions and beliefs. All statements other than statements of historical fact contained in this Prospectus Supplement, the Prospectus, or in the documents incorporated by reference herein and therein, are forward-looking statements, including, without limitation, the Corporation's business and the environment in which it operates, the Corporation's development and launch of new products, the Corporation's expectations regarding its production capacity and facility size, the Corporation's expectations regarding demand for cannabis and related products, the intention of the Corporation to complete the Offering on the terms and conditions described herein, general economic conditions, global events and applicable regulatory regimes, the expected timing regarding completion of the Offering, use of proceeds of the Offering, the exercise of the Over-Allotment Option, the anticipated effect of the Offering on the Corporation, the listing of any Unit Shares and Warrant Shares and the intention of the Corporation to use the MJDS to offer Units in the United States.

In certain cases, forward-looking statements can be identified by the use of words such as "plans", "expects", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", "projects", "believes", "pro forma" or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might" or "will", "occur" or "be achieved" and similar words or the negative thereof. Although management of the Corporation believes that the expectations represented in such forward-looking statements are reasonable, there can be no assurance that such expectations will prove to be correct. The forward-looking statements in this Prospectus Supplement and the Prospectus, including the documents incorporated by reference herein and therein, are based on certain assumptions, including a favourable capital markets environment in which to conduct the Offering, that construction, production, cultivation and distribution activities will proceed as planned and regulatory conditions will advance in the manner expected by management and that demand for cannabis and related products will change in the manner expected by management. They are not guarantees of future performance and involve risks and uncertainties that are difficult to control or predict. A number of factors could cause actual results to differ materially from the results discussed in the forward-looking statements, including, but not limited to, the factors discussed under the heading "Risk Factors" in this Prospectus Supplement, the Annual Information Form (as defined below) and the Interim MD&A (as defined below) and the other factors referenced in the Interim MD&A, including those relating to general economic conditions and global events; potential supply chain and distribution disruptions; product development, facility and technological risks; changes to government laws, regulations or policy, including environmental or tax, or the enforcement thereof; agricultural risks; expectations regarding the prospectus of the Corporation's collaboration and proposed investment transaction with a wholly-owned subsidiary of British American Tobacco p.l.c ("BAT"); expectations regarding the resolution of litigation and other legal proceedings; strategic investments and capital expenditures and expected related benefits; the price of cannabis and derivative cannabis products; and the Corporation's ability to maintain any required licenses or certifications. The Annual Information Form has also been filed with the SEC through the Electronic Data Gathering, Analysis, and Retrieval system ("EDGAR") as an exhibit to the Corporation's annual report on Form 40-F, and may be accessed on the SEC's website at www.sec.gov.

S-2

There can be no assurance that forward-looking statements will prove to be accurate as actual outcomes and results may differ materially from those expressed in these forward-looking statements. Readers, therefore, should not place undue reliance on any such forward-looking statements. Further, these forward-looking statements are made as of the date of this Prospectus Supplement and, except as expressly required by applicable law, the Corporation assumes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

ADDITIONAL INFORMATION

This Prospectus Supplement and the Prospectus, including the documents incorporated by reference into this Prospectus Supplement and the Prospectus, form part of the Registration Statement that we have filed with the SEC.  This Prospectus Supplement and the Prospectus, together do not contain all of the information contained in the Registration Statement, certain items of which have been omitted or are contained in the exhibits to the Registration Statement as permitted by the rules and regulations of the SEC. See "Documents Filed as Part of the Registration Statement". Statements included or incorporated by reference in this Prospectus Supplement about the contents of any contract, agreement or other documents referred to are not necessarily complete, and in each instance, you should refer to the exhibits for a complete description of the matter involved. Each such statement is qualified in its entirety by such reference.

The Corporation's Common Shares are registered under Section 12(b) of the United States Securities Exchange Act of 1934, as amended (the "U.S. Exchange Act"), and accordingly, we are subject to informational requirements of the U.S. Exchange Act and applicable Canadian requirements. In accordance with these informational requirements, we file reports and other information with the SEC and with securities regulatory authorities in Canada. Under the MJDS adopted by the United States and Canada, documents and other information that we file with the SEC may be prepared in accordance with the disclosure requirements of Canada, which are different from those of the United States. As a foreign private issuer, we are exempt from the rules under the U.S. Exchange Act prescribing the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the U.S. Exchange Act. Reports and other information filed by us with, or furnished to, the SEC may be accessed on the SEC's website at www.sec.gov. You may read and download any public document that we have filed with the securities commission or similar regulatory authority in each of the provinces and territories of Canada on the Canadian Securities Administrators' System for Electronic Document Analysis and Retrieval, or SEDAR+, at www.sedarplus.ca.

ENFORCEABILITY OF CIVIL LIABILITIES BY U.S. INVESTORS

The Corporation exists under the laws of Canada, and all of its executive offices, administrative activities and assets are located outside the United States. In addition, most of the directors and officers of the Corporation are residents of jurisdictions other than the United States and all or a substantial portion of the assets of those persons are or may be located outside the United States.

As a result, investors who reside in the United States may have difficulty serving legal process in the United States upon the Corporation or its directors or officers, as applicable, or enforcing judgments obtained in United States courts against any of them or the assets of any of them located outside the United States, or enforcing against them in the appropriate Canadian court judgments obtained in United States courts, including, but not limited to, judgments predicated upon the civil liability provisions of the federal securities laws of the United States, or bringing an original action in the appropriate Canadian courts to enforce liabilities against the Corporation or any of its directors or officers, as applicable, based upon United States federal securities laws.

In the United States, the Corporation has filed with the SEC, concurrently with the filing of its Registration Statement, an appointment of agent for service of process on Form F-X. Under such Form F-X, the Corporation has appointed Corporation Service Company of 1090 Vermont Avenue N.W., Washington, DC 20005, U.S.A., as its agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against the Corporation in a United States court arising out of or related to or concerning the Offering.

THE CORPORATION

The Corporation was incorporated under the Business Corporations Act (British Columbia) (the "BCBCA") on July 5, 2010 as "Inform Resources Corp." The Corporation changed its name to "0885160 B.C. Ltd." on September 13, 2010, and subsequently to "Inform Exploration Corp." ("Inform") on February 16, 2011. On November 21, 2011, Inform completed its initial public offering and its common shares commenced trading on the TSX-Venture Exchange (the "TSX-V") on November 24, 2011.

On August 22, 2014, Inform and Organigram Inc. entered into an acquisition agreement (the "Acquisition Agreement") pursuant to which Inform agreed, among other things, to change its name to "Organigram Holdings Inc." and to effect a consolidation of the outstanding Inform common shares on a 0.883604747 to 1 basis.

(1) Does not reflect the reduction of indebtedness as the allocation of the net proceeds of the Offering has yet to be determined.

USE OF PROCEEDS

The net proceeds to the Corporation from the Offering are estimated to be $23,812,690.50, after deducting the payment of the Underwriters' Fee of $1,187,509.50, but before deducting the expenses of the Offering (estimated to be approximately $465,000 which does not include legal fees of US counsel to the Underwriters). If the Over-Allotment Option is exercised in full, the net proceeds to the Corporation from the Offering are estimated to be $27,384,594.08, after deducting the payment of the Underwriters' Fee of $1,365,635.92, but before deducting the expenses of the Offering.

We intend to use the net proceeds from the Offering (including any net proceeds from the exercise of the Over-Allotment Option), as follows.

Purpose	Net Proceeds to the Corporation	Net Proceeds to the Corporation, including Over-Allotment Option
Growth initiatives	$11,906,345.25	$13,692,297.04
General corporate purposes	$11,906,345.25	$13,692,297.04
Total	$23,812,690.50	$27,384,594.08

The ultimate allocation of the net proceeds from the Offering may vary depending on future developments in the Corporation's business operations or unforeseen events, including those listed under the "Risk Factors" section of this Prospectus Supplement. For example, though the Corporation experienced positive operating cash flow for the three month period ending December 31, 2023, the Corporation had negative operating cash flow for the thirteen months ended September 30, 2023. To the extent that the Corporation has negative cash flows in future periods, the Corporation may use a greater portion of its general working capital to fund such negative cash flow than it would use if it had positive cash flows. Prospective purchasers are cautioned that, notwithstanding the Corporation's current intentions regarding the use of the net proceeds of the Offering, there may be circumstances where a reallocation of the net proceeds may be advisable for reasons that management believes, in its discretion, are in the Corporation's best interests.

S-6

DESCRIPTION OF THE SECURITIES

Offering

The Offering consists of 7,740,000 Units, with each Unit consisting of one Unit Share and one-half of a Warrant. Each Warrant will entitle the holder thereof to acquire one Warrant Share at an exercise price of $3.65 per Warrant Share, until 5:00 pm (Eastern time) on the date that is four years following the Closing Date, subject to adjustment in customary events. The Units will immediately separate into Unit Shares and Warrants upon issuance. The Units will not be certificated. This Prospectus Supplement also registers the issuances of the Warrant Shares.

Authorized Share Capital

The aauthorized capital of the Corporation consists of an unlimited number of Common Shares and an unlimited number of preferred shares (the “Preferred Shares”). As at the close of business on March 26, 2024 there were 94,468,558 Common Shares issued and outstanding; there are no Preferred Shares issued and outstanding.

Common Shares

The holders of the Common Shares are entitled to one vote per share at all meetings of the shareholders of the Corporation either in person or by proxy. The holders of Common Shares are also entitled to dividends, if and when declared by the directors of the Corporation and the distribution of the residual assets of the Corporation in the event of a liquidation, dissolution or winding up of the Corporation.

Dividends

As of the date of this Prospectus Supplement, the Corporation has not declared dividends and has no current intention to declare dividends on its Common Shares in the foreseeable future. Any decision to pay dividends on its Common Shares in the future will be at the discretion of the Corporation's board of directors ("Board") and will depend on, among other things, the Corporation's results of operations, current and anticipated cash requirements and surplus, financial condition, any future contractual restrictions and financing agreement covenants, solvency tests imposed by corporate law and other factors that the Board may deem relevant.

Warrants

The Warrants will be issued under and governed by the Warrant Indenture to be entered into on the Closing Date between the Corporation and TSX Trust Company, as warrant agent. The Corporation will appoint the principal transfer office of the TSX Trust Company in Toronto, Ontario as the location at which the Warrants may be surrendered for exercise, transfer or exchange. A register of holders will be maintained at the primary offices of the warrant agent in Toronto, Ontario. Under the Warrant Indenture, the Corporation may, subject to applicable law, purchase by private contract or otherwise, any of the Warrants then outstanding, and any Warrants so purchased will be cancelled.

Each Warrant will be transferable and will entitle the holder thereof to acquire one Warrant Share at an exercise price of $3.65 per Warrant Share, until 5:00 pm (Eastern Time) on the date that is four years following the Closing Date, subject to adjustment in certain customary events, after which time the Warrants will expire and become null and void. The Warrant Indenture will provide that, subject to compliance with applicable securities legislation and approval of applicable regulatory authorities, the Corporation will be entitled to purchase in the market, by private contract or otherwise, all or any of the Warrants then outstanding, and any Warrants so purchased will be cancelled.

S-7

The Warrant Indenture will provide for adjustment in the number of Warrant Shares issuable upon the exercise of the Warrants and/or the exercise price per Warrant Share upon the occurrence of certain events, including:

(a)the subdivision, redivision or change of the Common Shares into a greater number of Common Shares;

(b)the reduction, combination, or consolidation of the Common Shares into a lesser number of Common Shares;

(c)the issuance of Common Shares or securities exchangeable for or convertible into Common Shares to all or substantially all of the holders of the Common Shares by way of a distribution (other than a distribution of Warrant Shares upon the exercise of any Warrants);

(d)the issuance to all or substantially all of the holders of Common Shares of rights, options or warrants under which such holders are entitled, during a period expiring not more than 45 days after the record date for such issuance, to subscribe for or purchase Common Shares, or securities exchangeable for or convertible into Common Shares; and

(e)the distribution to all or substantially all of the holders of the Common Shares of shares of any class other than the Common Shares, rights, options or warrants to acquire Common Shares or securities exchangeable or convertible into Common Shares other than pursuant to item (d) above, of evidences of indebtedness, or any property or other assets.

The Warrant Indenture will also provide for adjustment in the class and/or number of securities issuable upon the exercise of the Warrants and/or exercise price per security in the event of the following additional events:

(a)reclassifications of the Common Shares or a capital reorganization of the Corporation;

(b)consolidations, amalgamations, arrangements or mergers of the Corporation with or into any other corporation, trust, partnership or other entity; or

(c)the sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity.

If, at any time, there is a Fundamental Transaction (as defined in the Warrant Indenture), then, without, for greater clarity, effect to the holder’s rights under the Warrant Indenture if the right is not exercised, written notice of the Fundamental Transaction shall be provided to the holders and each registered holder of Warrants shall have the right, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental Transaction), to cause the Corporation or any Successor Entity (as defined in the Warrant Indenture), to purchase his, her or its Warrants by paying to the holder an amount of cash equal to the Black Scholes Value (as defined in the Warrant Indenture) of the remaining unexercised portion of such Warrants on the date of the consummation of such Fundamental Transaction; provided, however, that, if the Fundamental Transaction is not within the Corporation's control, including not approved by the Corporation's board of directors, the holder shall only be entitled to receive from the Corporation or any Successor Entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of his, her or its Warrants, that is being offered and paid to the holders of Common Shares in connection with the Fundamental Transaction, whether that consideration be in the form of cash, shares or any combination thereof, or whether the holders of Common Shares are given the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction (whereby the holder shall be given the same choice) (each a “Successor Assumption”); provided, further, that if a Successor Assumption does not occur, the Corporation or the Successor Entity shall pay to the holder an amount equal to the aggregate value equal to the Black Scholes Value of the unexercised portion of his, her or its Warrants.

No adjustment in the exercise price or the number of Warrant Shares issuable upon the exercise of the Warrants will be required to be made unless the cumulative effect of such adjustment or adjustments would result in a change of at least 1% in the exercise price or a change in the number of Warrant Shares issuable upon exercise by at least one one-hundredth of a Warrant Share, as the case may be. Furthermore, no adjustment will be made in the right to acquire Warrant Shares if an issue of Common Shares is being made in connection with a share incentive plan, restricted share plan or share purchase plan for the benefit of directors, officers, employees, consultants or other service providers, or the satisfaction of existing instruments issued as of the date of the Warrant Indenture.

The Corporation will covenant in the Warrant Indenture that, during the period in which the Warrants are exercisable, it will give notice to TSX Trust Company and to the holders of the Warrants of certain stated events, including events that would result in an adjustment to the exercise price for the Warrants or the number of Warrant Shares issuable upon exercise of the Warrants, at least 14 days prior to the record date of such event, if any.

No fractional Warrant Shares will be issuable upon the exercise of any Warrants and no cash or other consideration will be paid in lieu of fractional Warrant Shares. Holders of Warrants will not have any voting or pre-emptive rights or any other rights which a holder of Common Shares would have.

The Corporation may provide certain buy-in rights to a holder if it fails to cause the Warrant Agent to deliver the Warrant Shares by three trading days after the delivery to the Corporation of the notice of exercise and the aggregate exercise price (or notice of cashless exercise). The buy-in rights apply if after the trading day after the date of such delivery by the holder, the holder purchases (in an open market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by the holder of the Warrant Shares that the holder anticipated receiving from the Corporation upon exercise of the Warrant. In this event, the Corporation will: (i) pay in cash to the holder the amount equal to the excess (if any) of the buy-in price (including brokerage commissions, if any) over the product of (A) such number of Warrant Shares, times (B) the price at which the sell order giving rise to holder’s purchase obligation was executed; and (ii) at the election of the holder, either (A) reinstate the portion of the Warrant as to such number of Warrant Shares, or (B) deliver to the holder a certificate or certificates representing such number of Warrant Shares that would have been issued to the holder had the Corporation complied with its delivery obligations under the Warrant Indenture.

The Warrant Indenture will include certain beneficial ownership limitations under which Warrants will not be exercisable to the extent that, after giving effect to the issuance of the Warrant Shares issuable upon such exercise of the Warrants, the holder, together with its affiliates and other persons acting as a group with the holder or any of its affiliates, would beneficially own in excess of 4.99% of the number of Common Shares outstanding immediately after giving effect to such issuance. Such beneficial ownership limitation may be increased or decreased by the holder upon notice to the Corporation, to a maximum of 9.99%. Except as provided in the Warrant Indenture, beneficial ownership will be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent the beneficial ownership limitations apply, the determination of whether a Warrant is exercisable and of which portion of a Warrant is exercisable shall be in the sole discretion and at the sole responsibility of the holder, and the submission of an exercise notice in respect of any Warrants shall be deemed to be the holder’s determination of whether the Warrants are exercisable, and neither the warrant agent nor the Corporation will have any obligation to verify or confirm the accuracy of such determination.

S-8

The Warrant Indenture will provide that the Corporation will use its best efforts to maintain the Registration Statement or another registration statement relating to the Warrant Shares effective until the earlier of the expiration date of the Warrants and the date on which no Warrants remain outstanding (provided, however, that nothing shall prevent the Corporation’s amalgamation, arrangement, merger or sale, including any take-over bid, and any associated delisting or deregistration or ceasing to be a reporting issuer, provided that, so long as the Warrants are still outstanding and represent a right to acquire securities of the acquiring Corporation, the acquiring Corporation shall assume the Corporation’s obligations under the Warrant Indenture). If no such registration statement is effective, no person holding Warrants will be permitted to exercise Warrants, unless an exemption or a safe harbor from the registration requirements of the U.S. Securities Act and applicable state securities laws is available. During any such period, any person holding Warrants may give notice of their desire to exercise the Warrants, at which time the Corporation will permit the cashless exercise of the Warrants and issue such number of Warrant Shares calculated pursuant to the provisions of the Warrant Indenture, provided that such Warrant Shares shall not be subject to any transfer restrictions in the United States or Canada. Notwithstanding the foregoing, if a person holding Warrants is not, and is not acting on behalf of or for the account or benefit of, a U.S. person or a person in the United States, such holder may exercise Warrants on a cash basis provided that the Warrants are exercised, and the underlying Warrant Shares are issued, in an “off shore transaction” (as defined in Rule 902(h) of Regulation S under the U.S. Securities Act), and the holder of Warrants certifies certain information in writing to the Corporation. If no such registration statement is effective, the Corporation will notify the holders of the Warrants in accordance with the provisions of the Warrant Indenture.

The Warrant Indenture will provide that, from time to time, the Corporation may amend or supplement the Warrant Indenture for certain purposes, without the consent of the holders of the Warrants, including curing defects or inconsistencies or making any change that does not prejudice the rights of any holder. Any amendment or supplement to the Warrant Indenture that would prejudice the interests of the holders of Warrants may only be made by "extraordinary resolution", which will be defined in the Warrant Indenture as a resolution either: (i) passed at a meeting of the holders of Warrants at which there are holders of Warrants present in person or represented by proxy representing at least 20% of the aggregate number of the then outstanding Warrants by the affirmative vote of the holders of Warrants representing not less than 66^2/3% of the aggregate number of Warrants represented at the meeting and voted on the poll upon such resolution; or (ii) adopted by an instrument in writing signed by the holders of Warrants representing not less than 66 ^2/3% of the aggregate number of all the then outstanding Warrants.

The foregoing summary of certain anticipated provisions of the Warrant Indenture does not purport to be complete and is qualified in its entirety by reference to the provisions of the Warrant Indenture in the form to be agreed upon by the parties. Reference should be made to the Warrant Indenture for the full text of attributes of the Warrants which will be filed by the Corporation under its corporate profile on SEDAR+ and EDGAR following the closing of the Offering.

PLAN OF DISTRIBUTION

Pursuant to the Underwriting Agreement, the Corporation has agreed to sell and the Underwriters have agreed to purchase on the Closing Date 7,740,000 Units at the Offering Price for aggregate net proceeds of $23,812,690.50, payable in cash (net of the Underwriters’ Fee) to the Corporation against delivery of the Units, subject to and in compliance with all necessary legal requirements and the conditions contained in the Underwriting Agreement. The Offering Price was determined by arms’ length negotiation between the Corporation and the Lead Underwriter, on behalf of the Underwriters, with reference to the prevailing market price of the Common Shares.

The obligations of the Underwriters under the Underwriting Agreement are several and are not joint, nor joint and several, and may be terminated at their discretion upon the occurrence of certain stated events as set out in the Underwriting Agreement. These include certain market disruption events, the suspension of trading in the Common Shares, a banking moratorium or related disruption events, certain material inquiries, investigations or proceedings, certain changes in law that prevent or materially restrict the distribution or trading of the Common Shares, certain material changes, a breach of material terms, conditions or covenants in the Underwriting Agreement or certain events relating to outbreak, escalation of hostilities, acts of terrorism and other events that may make it impracticable or inadvisable to proceed with the Offering. The Underwriters are, however, obligated to take up and pay for all of the Units (other than the Additional Units issuable pursuant to the Over-Allotment Option) if any of the Units are purchased under the Underwriting Agreement. In connection with the Offering, certain of the Underwriters or securities dealers may distribute this Prospectus Supplement and the Prospectus electronically.

The Offering is being made concurrently in all of the provinces and territories of Canada, except Quebec, and in the United States pursuant to the MJDS implemented by the SEC and the securities regulatory authorities in Canada. The Units will be offered in the United States and Canada by the Underwriters either directly or through their respective U.S. or Canadian broker-dealer affiliates or agents, as applicable. Subject to applicable law, the Underwriters may offer the Units outside of Canada and the United States.

S-9

The Corporation has granted the Underwriters the Over-Allotment Option, exercisable in whole or in part, at any time and from time to time, at the sole discretion of the Underwriters, for a period of 30 days from the Closing Date, to purchase up to an additional 15% of the Offering, which may be comprised of the acquisition of additional Units, Common Shares and/or Warrants, at the Offering Price, to cover over-allotments, if any, and for market stabilization purposes. This Prospectus Supplement, together with the Prospectus, qualifies the grant of the Over-Allotment Option and the Additional Securities issuable upon exercise of the Over-Allotment Option, as well as the Warrant Shares issuable upon exercise of any Additional Warrants. A purchaser who acquires Additional Securities issuable on the exercise of the Over-Allotment Option acquires such Additional Securities under this Prospectus Supplement regardless of whether the over-allotment position is ultimately filled through the exercise of the Over-Allotment Option or secondary market purchases. If the Over-Allotment Option is exercised in full, the total price to the public, the Underwriters' Fee and the net proceeds to the Corporation (before payment of the expenses of the Offering) will be $28,750,230, $1,365,635.92 and $27,384,594.08, respectively.

The Underwriters propose to offer the Units initially at the Offering Price specified on the cover page of this Prospectus Supplement. After the Underwriters have made a reasonable effort to sell all of the Units at the price specified on the cover page, the Offering Price may be decreased and may be further changed from time to time to an amount not greater than that set out on the cover page, and the compensation realized by the Underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Units is less than the price paid by the Underwriters to the Corporation. Upon execution of the Underwriting Agreement, the Underwriters will be obligated to purchase the Units, subject to the terms and conditions of the Underwriting Agreement, at the price and upon the terms stated therein and, as a result, will thereafter bear any risk associated with changing the Offering Price.

The Common Shares are listed for trading on the TSX and the NASDAQ under the trading symbol "OGI". The Corporation has applied to list the Unit Shares and the Warrant Shares on the TSX and has notified NASDAQ of the Offering. Listing is subject to the approval of the TSX and completion of NASDAQ's review process in accordance with their respective applicable listing requirements and will be subject to the Corporation fulfilling all of the listing requirements of the TSX and the NASDAQ. The Corporation does not intend to list the Warrants on any securities exchange. There is currently no market through which the Warrants may be sold and purchasers may not be able to resell Warrants purchased under this Prospectus Supplement. This may affect the pricing of the Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of the Warrants and the extent of issuer regulation. See "Risk Factors - Risks Related to the Offering - Market for the Warrants".

The closing of the Offering is anticipated to be on or about April 2, 2024 or such other date as may be agreed upon between the Corporation and the Lead Underwriter on behalf of the Underwriters (the "Closing Date").

The Unit Shares and Warrants comprising the Units will be deposited on the Closing Date with CDS or its nominee or DTC or its nominee, in either case, in electronic form, except in certain limited circumstances. A purchaser of Units will receive only a customer confirmation from the Underwriter or registered dealer from or through whom the Units are purchased and who is a CDS or DTC Participant.

Under the terms of the Underwriting Agreement, during the 90 days from the Closing Date, the Corporation will not, without the prior written consent of the Lead Underwriter (such consent not to be unreasonably withheld or delayed), directly or indirectly, issue, agree to issue, or announce an intention to issue, any Common Shares or any securities convertible into or exchangeable for Common Shares ("Relevant Security"), or enter into any agreement or arrangement under which the Corporation acquires or transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Shares or agree to become bound to do so, or disclose to the public any intention to do so, except with respect to: (i) the grant or exercise of stock options or other similar issuances pursuant to the Corporation’s equity compensation plans; (ii) the exercise of outstanding warrants existing on the date hereof; (iii) obligations of the Corporation in respect of existing agreements; (iv) the issuance of securities of the Corporation in connection with acquisitions in the normal course of business; or (iv) securities under the Offering (including, for greater certainty, Additional Securities under the Over-Allotment Option). In addition and notwithstanding any other provision of the Underwriting Agreement, the Corporation shall not, without the prior written consent of the Lead Underwriter, on behalf of the Underwriters, waive the restrictions set forth in Section 8.2 of the amended and restated investor rights agreement dated January 23, 2024 between the Corporation and BT DE Investments Inc. for a period of 90 days following the Closing Date.

S-10

It will be a condition of closing of the Offering that all directors, executive officers and certain other members of management of the Corporation (the "Locked-Up Parties") have entered into lock-up agreements (each, a "Lock-Up Agreement"), pursuant to which the Locked-Up Parties have agreed,  for a period of 90 days following the Closing Date (the "Lock-Up Period"), subject to limited exceptions, not to, directly or indirectly, offer, sell, contract to sell, lend, swap, or enter into any other agreement to transfer the economic consequences of, or otherwise dispose of or deal with, or publicly announce any intention to offer, sell, contract to sell, grant or sell any option to purchase, hypothecate, pledge, transfer, assign, purchase any option or contract to sell, lend, swap or enter into any agreement to transfer the economic consequences of, or otherwise dispose of or deal with, whether through the facilities of a stock exchange, by private agreement or otherwise, any Relevant Security, without the prior written consent of the Lead Underwriter on behalf of the Underwriters (such consent not to be unreasonably withheld), except in respect of (i) a bona fide take-over bid or any other similar transaction made generally to all of the securityholders of the Corporation, provided that, in the event the change of control or other similar transaction is not completed, such Relevant Securities shall remain subject to the Lock-Up Agreement; and (ii) any transfers to: (A) a spouse, parent, child or grandchild of the undersigned (a "Relative"); (B) corporations, partnerships, limited liability companies or other entities to the extent that such entities are wholly-owned by the undersigned; (C) trusts existing solely for the benefit of the undersigned and/or a Relative; or (D) a charitable organization pursuant to a bona fide gift, provided, however, that in the case of (ii), any such transferee will first execute a lock-up agreement in substantially the form of the Lock-Up Agreement, which will remain in force for the remainder of the Lock-up Period.

In connection with the Offering, the Underwriters may purchase and sell Common Shares in the open market, subject to the limitations described below. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of Common Shares in excess of the number of Common Shares to be purchased by the Underwriters in the Offering, which creates a syndicate short position. "Covered" short sales are sales of Common Shares made in an amount up to the number of Common Shares represented by the Over-Allotment Option. In determining the source of Common Shares to close out the covered syndicate short position, the Underwriters will consider, among other things, the price of Common Shares available for purchase in the open market as compared to the price at which they may purchase Common Shares through the Over-Allotment Option. Transactions to close out the covered syndicate short involve either purchases of the Common Shares in the open market after the distribution has been completed or the exercise of the Over-Allotment Option. The Underwriters may also make "naked" short sales of Common Shares in excess of the Over-Allotment Option. The Underwriters must close out any naked short position by purchasing Common Shares in the open market. A naked short position is more likely to be created if the Underwriters are concerned that there may be downward pressure on the price of the Common Shares in the open market after pricing that could adversely affect investors who purchase in the Offering. Stabilizing transactions consist of bids for or purchases of Common Shares in the open market while the Offering is in progress.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the Common Shares. They may also cause the price of the Common Shares to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The Underwriters may conduct these transactions in the over-the-counter market or otherwise. If the Underwriters commence any of these transactions, they may discontinue them at any time.

In accordance with policy statements of certain Canadian securities regulatory authorities and the Universal Market Integrity Rules for Canadian Marketplaces ("UMIR"), the Underwriters may not, at any time during the period of distribution, bid for or purchase Common Shares. The foregoing restriction is, however, subject to certain exceptions as permitted by such policy statements and UMIR. These exceptions include a bid or purchase permitted under the provisions of such policy statements and the UMIR relating to market stabilization and market balancing activities and a bid or purchase on behalf of a customer where the order was not solicited.

We have agreed to pay the Underwriters a cash commission equal to 4.75% of the gross proceeds of the Offering. We have also agreed to reimburse the Underwriters for reasonable expenses incurred in connection with the Offering, including reasonable legal fees.

We have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the U.S. Securities Act and applicable Canadian securities laws, or to contribute to payments the Underwriters may be required to make because of any of those liabilities.

S-11

Selling Restrictions

Other than in the United States and each of the provinces and territories of Canada, no action has been taken by the Corporation that would permit a public offering of the Units in any jurisdiction where action for that purpose is required. The Units may not be offered or sold, directly or indirectly, nor may this Prospectus Supplement or any other offering material or advertisements in connection with the offer and sale of any such Units be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this Prospectus Supplement comes are advised to inform themselves about and to observe any restrictions relating to the Offering and the distribution of this Prospectus Supplement. This Prospectus Supplement does not constitute an offer to sell or a solicitation of an offer to buy any Units in any jurisdiction in which such an offer or a solicitation is unlawful.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is, as of the date of this Prospectus Supplement, a general summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations thereunder (collectively, the "Tax Act") generally applicable to an investor who acquires as beneficial owner Unit Shares and Warrants comprising the Units pursuant to the Offering, and Warrant Shares upon exercise of such Warrants, and who, for the purposes of the Tax Act and at all relevant times, deals at arm's length with the Corporation and the Underwriters, is not affiliated with the Corporation or the Underwriters and who acquires and holds the Unit Shares, Warrants and Warrant Shares as capital property (a "Holder"). Generally, the Unit Shares, Warrants and Warrant Shares will be considered to be capital property to a Holder thereof provided that the Holder does not hold the Unit Shares, Warrants or Warrant Shares in the course of carrying on a business of trading or dealing in securities and such Holder has not acquired them in one or more transactions considered to be an adventure or concern in the nature of trade.

This summary does not apply to a Holder (i) that is a "financial institution" for the purposes of the mark-to-market rules contained in the Tax Act; (ii) that is a "specified financial institution" as defined in the Tax Act; (iii), an interest in which would be a "tax shelter investment" as defined in the Tax Act; (iv) that has made a functional currency reporting election under the Tax Act to report in a currency other than the Canadian dollar; (v) that has or will enter into a "derivative forward agreement" or a "synthetic disposition arrangement", as those terms are defined in the Tax Act, with respect to the Unit Shares, Warrants or Warrant Shares; or (vi) that receives dividends on the Unit Shares or Warrant Shares under or as part of a "dividend rental arrangement" as defined in the Tax Act. Such Holders should consult their own tax advisors with respect to an investment in the Units. This summary does not address (i) the deductibility of interest by a Holder who has borrowed money to acquire Unit Shares or Warrants comprising the Units pursuant to this Offering, or to acquire Warrant Shares upon the exercise of such Warrants, (ii) the tax treatment of any payments made in connection with the buy-in rights, or (iii) the application of the "split income" rules in section 120.4 of the Tax Act.

Additional considerations, not discussed herein, may be applicable to a Holder that is a corporation resident in Canada, and that is or becomes, or does not deal at arm's length for purposes of the Tax Act with a corporation resident in Canada that is or becomes, as part of a transaction or event or series of transactions or events that includes the acquisition of the Units or the Warrant Shares, controlled by a non-resident corporation or other person, or a group of non-resident persons (including corporations) not dealing with each other at arm's length, for purposes of the "foreign affiliate dumping" rules in section 212.3 of the Tax Act. Such Holders should consult their tax advisors with respect to the consequences of acquiring Units, including the acquisition of Warrant Shares pursuant to the exercise of the Warrants.

This summary is based upon the current provisions of the Tax Act in force as of the date hereof and counsel's understanding of the current published administrative and assessing practices of the Canada Revenue Agency (the "CRA"). This summary takes into account all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Tax Proposals") and assumes that the Tax Proposals will be enacted in the form proposed, although no assurance can be given that the Tax Proposals will be enacted in their current form or at all. This summary does not otherwise take into account any changes in law or in the administrative policies or assessing practices of the CRA, whether by legislative, governmental or judicial decision or action, nor does it take into account or consider any provincial, territorial or foreign income tax considerations, which considerations may differ significantly from the Canadian federal income tax considerations discussed in this summary.

S-13

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder. Holders should consult their own tax advisors with respect to their particular circumstances.

Allocation of Offering Price

Holders will be required to allocate the aggregate cost of a Unit between the Unit Share and the Warrant on a reasonable basis in order to determine their respective costs for the purposes of the Tax Act. The Corporation intends to allocate as consideration for their issue $2.83 to each Unit Share and $0.40 per half Warrant acquired as part of a Unit. As of the date of this Prospectus Supplement, the Corporation believes that such allocation is reasonable but such allocation will not be binding on the CRA or a Holder. The adjusted cost base to a Holder of a Unit Share acquired as part of a Unit will be determined by averaging the cost of such Unit Share with the adjusted cost base of all Common Shares of the Corporation held by the Holder as capital property immediately before such acquisition.

Exercise of Warrants

No gain or loss will be realized by a Holder on the exercise of a Warrant to acquire a Warrant Share. When a Warrant is exercised, the Holder's cost of the Warrant Share acquired thereby will be equal to the aggregate of the Holder's adjusted cost base of such Warrant and the exercise price paid for the Warrant Share. The Holder's adjusted cost base of the Warrant Share so acquired will be determined by averaging the cost of the Warrant Share with the adjusted cost base to the Holder of all Common Shares of the Corporation held as capital property immediately before the acquisition of the Warrant Share.

Residents of Canada

The following section of this summary applies to Holders who, for the purposes of the Tax Act, are or are deemed to be resident in Canada at all relevant times ("Resident Holders"). Certain Resident Holders whose Unit Shares or Warrant Shares might not constitute capital property may make, in certain circumstances, an irrevocable election permitted by subsection 39(4) of the Tax Act to deem the Unit Shares or Warrant Shares, and every other "Canadian security" as defined in the Tax Act, held by such persons, in the taxation year of the election and each subsequent taxation year to be capital property. This election does not apply to Warrants. Resident Holders should consult their own tax advisors regarding this election.

Expiry of Warrants

The expiry of an unexercised Warrant generally will result in a capital loss to the Resident Holder equal to the adjusted cost base of the Warrant to the Resident Holder immediately before its expiry. See discussion below under the heading "Capital Gains and Capital Losses".

Dividends

Dividends received or deemed to be received on the Unit Shares or Warrant Shares are required to be included in computing a Resident Holder's income. In the case of a Resident Holder that is an individual (other than certain trusts), such dividends will be subject to the gross-up and dividend tax credit rules normally applicable in respect of "taxable dividends" received from "taxable Canadian corporations" (each as defined in the Tax Act). An enhanced dividend tax credit will be available to individuals in respect of "eligible dividends" designated by the Corporation to the Resident Holder in accordance with the provisions of the Tax Act. A dividend will be an eligible dividend if the recipient receives written notice (which may include a notice published on the Corporation's website) from the Corporation designating the dividend as an "eligible dividend". There may be limitation on the Corporation's ability to designate dividends as "eligible dividends".

Dividends received or deemed to be received by a corporation that is a Resident Holder on the Unit Shares or Warrant Shares are required to be included in computing its income but generally will be deductible in computing its taxable income. In certain circumstances, section 55(2) of the Tax Act will treat a taxable dividend received (or deemed to be received) by a Resident Holder that is a corporation as proceeds of dispositions or a capital gain. Resident Holders that are corporations should consult their own tax advisors having regard to their own circumstances.

S-14

A Resident Holder that is a "private corporation" (as defined in the Tax Act) or a corporation controlled, whether because of a beneficial interest in one or more trusts, or otherwise, by or for the benefit of an individual (other than a trust) or related group of individuals (other than trusts) generally will be liable to pay a refundable tax under Part IV of the Tax Act on dividends received or deemed to be received on the Unit Shares or Warrant Shares to the extent such dividends are deductible in computing the Resident Holder's taxable income for the year. A Resident Holder that is throughout the relevant taxation year a "Canadian-controlled private corporation" (as defined in the Tax Act) may be liable to pay a refundable tax on its "aggregate investment income" for the year, which includes any dividends or deemed dividends that are not deductible in computing the Resident Holder's taxable income. Proposed amendments to the Tax Act extend this additional tax and refund mechanism in respect of aggregate investment income to "substantive CCPCs" (as defined in such proposed amendments), and introduce anti-avoidance rules that may deem certain corporations resident in Canada that do not otherwise qualify as "substantive CCPCs" to so qualify. Resident Holders are advised to consult their own tax advisors in this regard.

Dispositions of Unit Shares, Warrants and Warrant Shares

Upon a disposition (or a deemed disposition) of a Unit Share, a Warrant (other than on the expiry or exercise thereof) or a Warrant Share, a Resident Holder generally will realize a capital gain (or a capital loss) equal to the amount, if any, by which the proceeds of disposition of such Unit Share, Warrant or Warrant Share, net of any reasonable costs of disposition, are greater (or are less) than the adjusted cost base of such Unit Share, Warrant or Warrant Share to the Resident Holder. The tax treatment of capital gains and capital losses is discussed in greater detail below under the subheading "Capital Gains and Capital Losses".

The adjusted cost base to a Resident Holder of a Unit Share acquired pursuant to the Offering or a Warrant Share acquired pursuant to the exercise of a Warrant will be averaged with the adjusted cost base of any other Common Shares of the Corporation held by such Resident Holder as capital property immediately before the relevant acquisition for the purposes of determining the Resident Holder's adjusted cost base of each Unit Share or Warrant Share.

Capital Gains and Capital Losses

Generally, a Resident Holder is required to include in computing its income for a taxation year one-half of the amount of any capital gain (a "taxable capital gain") realized in the year. Subject to and in accordance with the provisions of the Tax Act, a Resident Holder is required to deduct one-half of the amount of any capital loss (an "allowable capital loss") realized in a taxation year from taxable capital gains realized in the year by such Resident Holder. Allowable capital losses in excess of taxable capital gains may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any following taxation year against net taxable capital gains realized in such year to the extent and under the circumstances described in the Tax Act.

The amount of any capital loss realized on the disposition or deemed disposition of Unit Shares or Warrant Shares by a Resident Holder that is a corporation may be reduced by the amount of dividends received or deemed to have been received by it on such shares or shares substituted for such shares to the extent and in the circumstances specified by the Tax Act. Analogous rules apply to a partnership or trust of which a corporation, trust or partnership is a member or beneficiary. Resident Holders to whom these rules may be relevant should consult their own tax advisors.

A Resident Holder that is throughout the relevant taxation year a "Canadian-controlled private corporation" (as defined in the Tax Act) may be liable to pay a refundable tax on its "aggregate investment income" for the year, which will include taxable capital gains. Proposed amendments to the Tax Act extend this additional tax and refund mechanism in respect of aggregate investment income to "substantive CCPCs" (as defined in such proposed amendments), and introduce anti-avoidance rules that may deem certain corporations resident in Canada that do not otherwise qualify as "substantive CCPCs" to so qualify. Resident Holders are advised to consult their own tax advisors in this regard.

Minimum Tax

Capital gains realized and dividends received by a Resident Holder that is an individual (other than certain trusts) may give rise to minimum tax under the Tax Act. Resident Holders should consult their own advisors with respect to the application of minimum tax.

S-15

Non-Residents of Canada

The following section of this summary is generally applicable to Holders who (i) for the purposes of the Tax Act, have not been and will not be deemed to be resident in Canada at any time while they hold the Unit Shares, Warrants or Warrant Shares; and (ii) do not use or hold the Unit Shares, Warrants or Warrant Shares in carrying on a business in Canada ("Non-Resident Holders"). Special rules, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer carrying on business in Canada and elsewhere or to an "authorized foreign bank" (as defined in the Tax Act). Such Holders should consult their own tax advisors.

Dividends

Dividends paid or credited or deemed to be paid or credited on the Unit Shares or Warrant Shares to a Non-Resident Holder are subject to Canadian withholding tax at the rate of 25% on the gross amount of the dividend unless such rate is reduced by the terms of an applicable tax treaty. For example, under the Canada-United States Tax Convention (1980), as amended (the "Treaty"), the rate of withholding tax on dividends paid or credited to a Non-Resident Holder who is resident in the U.S. for purposes of the Treaty and entitled to benefits under the Treaty ( for the purposes of this summary, a "U.S. Holder") is generally limited to 15% of the gross amount of the dividend.

Dispositions of Unit Shares, Warrants and Warrant Shares

A Non-Resident Holder generally will not be subject to tax under the Tax Act in respect of a capital gain realized on the disposition or deemed disposition of a Unit Share, Warrant or Warrant Share nor will capital losses arising therefrom be recognized under the Tax Act, unless the Unit Share, Warrant or Warrant Share constitutes "taxable Canadian property" to the Non-Resident Holder thereof for purposes of the Tax Act, and the gain is not exempt from tax pursuant to the terms of an applicable tax treaty or convention.

Provided the Unit Shares and Warrant Shares are listed on a "designated stock exchange", as defined in the Tax Act (which currently includes the TSX and the NASDAQ), at the time of disposition, the Unit Shares, Warrants and Warrant Shares generally will not constitute taxable Canadian property of a Non-Resident Holder at that time, unless at any time during the 60-month period immediately preceding the disposition, the following two conditions are met: (i) 25% or more of the issued shares of any class or series of the share capital of the Corporation were owned by, or belonged to, one or any combination of (x) the Non-Resident Holder, (y) persons with whom the Non-Resident Holder did not deal at arm's length (within the meaning of the Tax Act), and (z) partnerships in which the Non-Resident Holder or a person referred to in (y) holds a membership interest directly or indirectly through one or more partnerships, and (ii) more than 50% of the fair market value of the Common Shares, was derived directly or indirectly from one or any combination of: (A) real or immovable property situated in Canada, (B) Canadian resource property (as defined in the Tax Act), (C) timber resource property (as defined in the Tax Act), and (D) options in respect of, or interests in, or for civil law rights in, property described in any of (A) through (C) above, whether or not such property exists.

A Non-Resident Holder's capital gain (or capital loss) in respect of Unit Shares, Warrants or Warrant Shares that constitute or are deemed to constitute taxable Canadian property (and are not "treaty-protected property" as defined in the Tax Act) will generally be computed in the manner described above under the subheading "Residents of Canada-Dispositions of Unit Shares, Warrants and Warrant Shares".

Non-Resident Holders whose Unit Shares, Warrants or Warrant Shares are taxable Canadian property should consult their own tax advisors, including with respect to any notification or tax filing obligations under the Tax Act.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain material U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of Unit Shares and Warrants comprising the Units pursuant to the Offering, and Warrant Shares upon exercise of the Warrants, that was prepared by Hodgson Russ LLP, counsel to the Corporation with respect to U.S. federal income tax matters.

S-16

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder arising from and relating to the acquisition, ownership, and disposition of Unit Shares, Warrants or Warrant Shares. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including, without limitation, specific tax consequences to a U.S. Holder under an applicable income tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder. Except as set forth below, this summary does not address the U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences to U.S. Holders of the acquisition, ownership, and disposition of Unit Shares, Warrants or Warrant Shares, nor any applicable tax reporting requirements. Each prospective U.S. Holder should consult their own tax advisors regarding the U.S. federal, U.S. federal net investment income,, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences and tax reporting requirements relating to the acquisition, ownership, and disposition of Unit Shares, Warrants or Warrant Shares.

No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (the "IRS") has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Unit Shares, Warrants or Warrant Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary are based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.

Scope of this Summary

Authorities

This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations (whether final, temporary, or proposed), published rulings of the IRS, published administrative positions of the IRS, the Treaty, and U.S. court decisions that are applicable, and, in each case, as in effect and available, as of the date of this Prospectus Supplement. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied retroactively or prospectively. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.

U.S. Holders

For purposes of this summary, the term "U.S. Holder" means a beneficial owner of Unit Shares, Warrants or Warrant Shares that is for U.S. federal income tax purposes:

•an individual who is a citizen or resident of the United States;

•a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States, any state thereof or the District of Columbia;

•an estate whose income is subject to U.S. federal income taxation regardless of its source; or

•a trust that (1) is subject to the primary supervision of a court within the United States and is under the control of one or more U.S. persons for all substantial decisions or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

Non-U.S. Holders

For purposes of this summary, a "non-U.S. Holder" is a beneficial owner of Unit Shares, Warrants or Warrant Shares that is not a U.S. Holder or partnership or other pass-through entity. This summary does not address the U.S. federal income tax consequences applicable to non-U.S. Holders. Accordingly, a non-U.S. Holder should consult its own tax advisor regarding the tax consequences (including the potential application of and operation of any income tax treaties) related to the acquisition, ownership and disposition of Unit Shares, Warrants or Warrant Shares.

S-17

U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders that: (a) are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) are broker-dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting method; (d) have a "functional currency" other than the U.S. dollar; (e) own Unit Shares, Warrants or Warrant Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) acquire Unit Shares, Warrants or Warrant Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) hold Unit Shares, Warrants or Warrant Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) are required to accelerate the recognition of any item of gross income with respect to Unit Shares, Warrants or Warrant Shares as a result of such income being recognized on an applicable financial statement; or (i) own, have owned or will own (directly, indirectly, or by attribution) 10% or more of the total combined voting power or value of the outstanding shares of the Corporation.

This summary also does not address the U.S. federal income tax considerations applicable to U.S. Holders who are: (a) U.S. expatriates or former long-term residents of the U.S.; (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Tax Act; (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Unit Shares, Warrants or Warrant Shares in connection with carrying on a business in Canada; (d) persons whose Unit Shares, Warrants or Warrant Shares constitute "taxable Canadian property" under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Treaty and that use or hold Unit Shares, Warrants or Warrant Shares in connection with such permanent establishment.

U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders described immediately above, should consult their own tax advisors regarding the U.S. federal, U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of Unit Shares, Warrants or Warrant Shares.

If an entity or arrangement that is classified as a partnership (or other "pass-through" entity) for U.S. federal income tax purposes holds Unit Shares, Warrants or Warrant Shares, the U.S. federal income tax consequences to such entity and the partners (or other owners) of such entity generally will depend on the activities of the entity and the status of such partners (or owners). This summary does not address the tax consequences to any such partner (or owner). Partners (or other owners) of entities or arrangements that are classified as partnerships or as "pass-through" entities for U.S. federal income tax purposes should consult their own tax advisors regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of Unit Shares, Warrants or Warrant Shares.

In addition, this summary assumes that the Corporation is not a "controlled foreign corporation" for U.S. federal income tax purposes.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE, LOCAL, AND NON-U.S. TAX CONSEQUENCES AND REPORTING REQUIREMENTS TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF UNIT SHARES, WARRANTS OR WARRANT SHARES.

Each Unit should be treated for U.S. federal income tax purposes as an investment unit consisting of one Unit Share and one-half Warrant. For U.S. federal income tax purposes, U.S. Holders will be required to allocate the purchase price of the Unit between the Unit Share and the one-half Warrant based on their relative fair market values at the time of issuance. This allocation of the purchase price for the Unit will establish such U.S. Holder's initial tax basis for U.S. federal income tax purposes in the Unit Share and the one-half Warrant comprising the Unit.

S-18

The Corporation intends to allocate as consideration for their issue $2.83 to each Unit Share and $0.40 per half Warrant acquired as part of a Unit. As of the date of this Prospectus Supplement, the Corporation believes that such allocation is reasonable but such allocation will not be binding on the IRS. Each U.S. Holder should consult its own tax advisor regarding the allocation of the purchase price for the Units.

Exercise, Disposition or Expiration of Warrants (Assuming the Corporation is not a "Passive Foreign Investment Company" ("PFIC")

The following discussion is subject in its entirety to the rules described below under the heading "Passive Foreign Investment Company Rules".

Exercise of Warrants

The U.S. federal income tax treatment of the exercise of a Warrant is uncertain, and the U.S. tax consequences of the exercise of a Warrant could differ from what is described herein. Subject to the foregoing sentence, and the discussion below under "Passive Foreign Investment Company Rules", a U.S. Holder generally should not recognize gain or loss on the exercise of a Warrant and related receipt of a Warrant Share. A U.S. Holder's initial tax basis in the Warrant Share received on the exercise of a Warrant should be equal to the sum of (a) such U.S. Holder's tax basis in such Warrant plus (b) the exercise price paid by such U.S. Holder on the exercise of such Warrant. The holding period for the Warrant Share may or may not include the period during which the U.S. Holder held the Warrant. Each U.S. Holder should consult its own tax advisor regarding the proper treatment of an exercise of a Warrant and the tax basis in, and the holding period for, the Warrant Share received on such exercise.

Sale or Other Taxable Disposition of Warrants

A U.S. Holder will recognize gain or loss on the sale or other taxable disposition of a Warrant in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder's tax basis in the Warrant sold or otherwise disposed of. Subject to the discussion under "Passive Foreign Investment Company Rules" below, any such gain or loss generally will be a capital gain or loss (provided that the Warrant Share to be issued on the exercise of such Warrant would have been a capital asset within the meaning of Section 1221 of the Code if acquired by the U.S. Holder), which will be long-term capital gain or loss if the Warrant is held for more than one year.

Expiration of Warrants Without Exercise

Subject to the discussion under "Passive Foreign Investment Company Rules" below, upon the lapse or expiration of a warrant, a U.S. Holder will recognize a loss in an amount equal to such U.S. Holder's tax basis in the Warrant. Any such loss generally will be a capital loss and will be long-term capital loss if the Warrants are held for more than one year. Deductions for capital losses are subject to complex limitations under the Code.

Certain Adjustments to the Warrants

Under Section 305 of the Code, an adjustment to the number of Warrant Shares that will be issued on the exercise of the Warrants, or an adjustment to the exercise price of the Warrants may be treated as a constructive distribution to a U.S. Holder of the Warrants if, and to the extent that, such adjustment has the effect of increasing such U.S. Holder's proportionate interest in the "earnings and profits" or assets of the Corporation, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to shareholders of the Corporation). In addition, an adjustment made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing dilution of the interest of the holders of the Warrants generally should not be considered to result in a constructive distribution. Each U.S. Holder should consult its own tax advisor regarding the proper treatment of any adjustment to the number of Warrant Shares that will be issued on the exercise of the Warrants or an adjustment to the exercise price of the Warrants.

Ownership and Disposition of Unit Shares or Warrant Shares (Assuming the Corporation is not a PFIC)

The following discussion is subject in its entirety to the rules described below under the heading "Passive Foreign Investment Company Rules".

S-19

Distributions on Unit Shares or Warrant Shares

A U.S. Holder that receives a distribution, including a constructive distribution, with respect to a Unit Share or Warrant Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any foreign income tax withheld from such distribution) to the extent of the current or accumulated "earnings and profits" of the Corporation, as computed for U.S. federal income tax purposes. To the extent that a distribution exceeds the current and accumulated "earnings and profits" of the Corporation, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder's tax basis in the Unit Shares or Warrant Shares and thereafter as gain from the sale or exchange of such Unit Shares or Warrant Shares (see "Sale or Other Taxable Disposition of Unit Shares or Warrant Shares" below). However, the Corporation may not maintain the calculations of its earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder may have to assume that any distribution by the Corporation with respect to the Unit Shares or Warrant Shares will constitute dividend income. Dividends received on Unit Shares or Warrant Shares by corporate U.S. Holders generally will not be eligible for the "dividends received deduction"allowed to corporations in respect of dividends received from other U.S. corporations or, absent the corporate U.S. Holder meeting certain ownership thresholds, the dividends-received deduction available in respect of dividends received from certain foreign corporations. Subject to applicable limitations and provided the Corporation is eligible for the benefits of the Treaty or the Unit Shares or Warrant Shares are readily tradable on a United States securities market, dividends paid by the Corporation to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to qualified dividends, provided certain holding period and other conditions are satisfied, including that the Corporation not be classified as a PFIC in the tax year of distribution or in the preceding tax year.

For U.S. federal income tax purposes, U.S. Holders will be treated as having received the amount of any Canadian taxes withheld by the Corporation, and as then having paid over the withheld taxes to the Canadian taxing authorities. As a result of this rule, the amount of dividend income included in gross income for U.S. federal income tax purposes by a U.S. Holder with respect to a payment of dividends may be greater than the amount of cash actually received (or receivable) by the U.S. Holder from the Corporation with respect to the payment.

The dividend rules are complex, and each U.S. Holder should consult its own tax advisor regarding the application of such rules.

Sale or Other Taxable Disposition of Unit Shares or Warrant Shares

A U.S. Holder will recognize gain or loss on the sale or other taxable disposition of Unit Shares or Warrant Shares in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder's tax basis in such Unit Shares or Warrant Shares sold or otherwise disposed of. Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if, at the time of the sale or other disposition, such Unit Shares or Warrant Shares are held for more than one year. If the consideration a U.S. Holder receives for the Unit Shares or Warrant Shares is not paid in U.S. dollars, the amount realized will be determined using the rules described under "Additional Considerations-Use of Foreign Currency to Acquire Unit Shares, Warrants or Warrant Shares or Receipt of Foreign Currency." A U.S. Holder's tax basis in its Unit Shares or Warrant Shares generally will equal the U.S. dollar cost of such Unit Shares or Warrant Shares. If a U.S. Holder uses foreign currency to acquire Unit Shares or Warrant Shares, the cost of the Unit Shares or Warrant Shares will be determined using the rules described under "Additional Considerations-Use of Foreign Currency to Acquire Unit Shares, Warrants or Warrant Shares or Receipt of Foreign Currency."

Preferential tax rates apply to long-term capital gains of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Passive Foreign Investment Company Rules

For purposes of the following discussion, the term "Common Shares" is intended to refer to both "Unit Shares" and "Warrant Shares".

U.S. Holders generally would be subject to a special, adverse tax regime that would differ in certain respects from the tax treatment described above if the Corporation is, or were to become, a PFIC for U.S. federal income tax purposes. The determination as to whether a non-U.S. corporation is a PFIC is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, and on many factors that can change from time to time, including fluctuations in the market price of the Corporation's Common Shares. The general rule is that the Corporation would be a PFIC if, for a tax year, (a) 75% or more of its gross income for such tax year is passive income or (b) 50% or more of the value of its gross assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets. "Gross income" generally includes all sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and "passive income" generally includes dividends, interest, certain rents and royalties, and certain types of gains (such as from the sale of stock and securities). For purposes of determining whether the Corporation is a PFIC, the Corporation will be treated as holding its proportionate share of the assets and receiving directly its proportionate share of the income of any other corporation in which it owns, directly or indirectly, 25% or more (by value) of the stock of such other corporation. If the Corporation is a PFIC and owns less than a 25% interest by value in another non-U.S. corporation, it is possible such other corporation could also be considered a PFIC with respect to a U.S. Holder of the Common Shares.

S-20

The Corporation has not made any determination of its PFIC status for the current year. The Corporation also has not made a PFIC determination for any prior taxable year. Therefore, there is no assurance that the Corporation has not been a PFIC in prior taxable years, nor that the Corporation will not be a PFIC in its current taxable year or become a PFIC in any future taxable year. No opinion is expressed with respect to the Corporation’s PFIC status for prior, current or future taxable years. If the Corporation is or becomes a PFIC with respect to Common Shares held by a particular U.S. Holder, it will always be considered a PFIC with respect to such Common Shares of the U.S. Holder even if the Corporation may not otherwise qualify as a PFIC in future years.

If the Corporation is a PFIC with respect to a U.S. Holder, and the U.S. Holder does not make either of the elections described below, gain from the disposition of the Common Shares and certain distributions classified as "excess distributions" (generally, those that are in excess of 125% of the average amount of distributions in the three prior tax years) would be subject to ordinary income treatment and allocated ratably to days in a U.S. Holder's holding period in computing the U.S. Holder's tax liability. The amounts allocated to the taxable year during which the gain is realized or excess distribution is made, and to any taxable years in such U.S. Holder's holding period that are before the first taxable year in which the Corporation is treated as a PFIC with respect to that U.S. Holder, would be included in the U.S. Holder's gross income as ordinary income for the taxable year of the gain or excess distribution. The amount allocated to each other taxable year would be taxed as ordinary income in the taxable year during which the gain is realized or excess distribution is made at the highest tax rate in effect for the U.S. Holder in that other taxable year and would be subject to an interest charge as if the income tax liabilities had been due with respect to each such prior year. Under proposed Treasury Regulations, gifts, exchanges pursuant to corporate reorganizations and pledging or use of Common Shares as security for a loan would be treated as a taxable disposition of the Common Shares and subject to the foregoing tax treatment. Furthermore, proposed Treasury Regulations generally treat "options" to acquire stock of a PFIC as actually being stock in the PFIC, and "options" for this purpose would include the Warrants

If the Corporation is a PFIC, the U.S. Holder may be able to mitigate the adverse tax effects of the PFIC rules described above if the U.S. Holder makes a "qualified electing fund" ("QEF") or a "mark-to-market" election with respect to the Unit Shares or the Warrant Shares. (The QEF election or mark-to-market election is currently not permitted with respect to the Warrants.). If a U.S. Holder makes a timely QEF election for the first tax year in which its holding period of its Common Shares begins, such U.S. Holder generally will not be subject to the PFIC rules described above with respect to such Common Shares. However, under the QEF regime, in each taxable year that the Corporation is considered a PFIC the U.S. Holder must include in gross income (i) as ordinary income, the U.S. Holder's pro rata share of the ordinary earnings of the Corporation and (ii) as capital gain, the U.S. Holder's pro rata share of the net capital gain of the Corporation, regardless of whether the Corporation makes a distribution on the Common Shares. Distributions of income that had previously been taxed under the QEF regime will not be taxed again when such distributions are made to the U.S. Holder. Subject to certain restrictions, a U.S. Holder may elect to defer payment of current U.S. federal income tax on such amounts included in income under the QEF regime, but a non-deductible interest charge would be applied. Under the QEF rules, the electing U.S. Holder must supply certain information to the IRS that the U.S. Holder would need to obtain from the Corporation. If the Corporation has reason to believe it may be a PFIC in a particular taxable year, and if so requested by a U.S. Holder for such taxable year, the Corporation will use commercially reasonable efforts to make available such information to the U.S. Holder.

If the Corporation is a PFIC, a U.S. Holder (other than with respect to the Warrants) may make a "mark-to-market" election as an alternative to a QEF election, as long as the Common Shares are treated as regularly traded on a qualified exchange or other market within the meaning of the applicable Treasury Regulations. The consequence of a mark- to-market election is that a U.S. Holder must include in his gross income, as ordinary income, an amount equal to the excess, if any, of the fair market value of the U.S. holder's Common Shares at the close of the taxable year over the U.S. Holder's adjusted tax basis in the Common Shares. If the fair market value of the U.S. Holder's Common Shares at the end of the taxable year is less than the adjusted tax basis of the U.S. Holder in the Common Shares, an ordinary loss deduction may be claimed, but only to the extent of any mark-to-market gains previously included in income. The U.S. Holder's tax basis in the Common Shares will be adjusted to reflect such inclusions or deductions. Gain or loss on disposition of the Common Shares will be ordinary income or loss.

S-21

During any taxable year in which the Corporation or any of its subsidiaries is treated as a PFIC with respect to a U.S. Holder, that U.S. Holder may be required to file IRS Form 8621, ("Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund").

A U.S. Holder should consult their own tax advisor regarding the potential applicability of the PFIC rules to an investment in the Units, Unit Shares and Warrant Shares, as well as the potential availability, and advisability of making a QEF election (including on a protective basis) or a mark-to-market election, and any applicable U.S. reporting obligations.

Additional Considerations

Additional Tax on Passive Income

Certain individuals, estates and trusts whose income exceeds certain thresholds will be required to pay a 3.8% Medicare surtax on "net investment income" including, among other things, dividends and net gain from disposition of property (other than property held in certain trades or businesses). U.S. Holders should consult their own tax advisors regarding the application, if any, of this tax on their ownership and disposition of Unit Shares, Warrants or Warrant Shares.

Use of Foreign Currency to Acquire Unit Shares, Warrants or Warrant Shares or Receipt of Foreign Currency

A U.S. Holder's tax basis in its Unit Shares, Warrants or Warrant Shares generally will equal the U.S. dollar cost of such Unit Shares, Warrants or Warrant Shares. If a U.S. Holder uses foreign currency to purchase Unit Shares, Warrants or Warrant Shares, the cost of the Unit Shares, Warrants or Warrant Shares will be the U.S. dollar value of the foreign currency purchase price determined by reference to the spot rate of exchange on the date of purchase. However, if the Unit Shares, Warrants or Warrant Shares are treated as traded on an established securities market and the U.S. Holder is either a cash basis taxpayer or an accrual basis taxpayer who has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS), such U.S. Holder will determine the U.S. dollar value of the cost of such Unit Shares, Warrants or Warrant Shares by translating the amount paid at the spot rate of exchange on the settlement date of the purchase.

The amount of any distribution paid to a U.S. Holder in foreign currency, or on the sale, exchange or other taxable disposition of Unit Shares, Warrants or Warrant Shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). However, in the case of sale, exchange, or other taxable disposition of Unit Shares, Warrants or Warrant Shares, if the Unit Shares, Warrants or Warrant Shares are treated as traded on an "established securities market" and the U.S. Holder is either a cash basis taxpayer or an accrual basis taxpayer that has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS), such U.S. Holder will determine the U.S. dollar value of the amount realized in a foreign currency by translating the amount received at the spot rate of exchange on the settlement date of the sale.

A U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who converts or otherwise disposes of the foreign currency after the date of receipt may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. Each U.S. Holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

S-22

Foreign Tax Credit

Subject to the PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Unit Shares or Warrant Shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax. Generally, a credit will reduce a U.S. Holder's U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder's income that is subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year. The foreign tax credit rules are complex and involve the application of rules that depend on a U.S. Holder's particular circumstances. Accordingly, each U.S. Holder should consult its own U.S. tax advisor regarding the foreign tax credit rules.

Backup Withholding and Information Reporting

Under U.S. federal income tax law and Treasury Regulations, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, there may be a requirement to file an IRS Form 8938 ("Statement of Specified Foreign Financial Assets"), with a U.S. Holder's U.S. tax return, under special rules that impose U.S. return disclosure obligations (and related penalties) on individuals who are U.S. Holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also may include assets such as Unit Shares, Warrants or Warrant Shares. Other IRS information reporting on various IRS Forms may also be required with respect to a U.S. Holder. Penalties for failure to file required information returns are substantial. U.S. Holders should consult their own tax advisors regarding the requirements of filing information returns.

Payments made within the U.S. or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, Unit Shares, Warrants or Warrant Shares will generally be subject to information reporting and backup withholding tax if a U.S. Holder (a) fails to furnish such U.S. Holder's correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding tax rules will be allowed as a credit against a U.S. Holder's U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner.

During any taxable year in which the Corporation or any of its subsidiaries is treated as a PFIC with respect to a particular U.S. Holder, that U.S. Holder generally may have additional U.S. reporting requirements, as described above under "Passive Foreign Investment Company Rules"

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax, and under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. Holder should consult its own tax advisor regarding the information reporting and backup withholding rules.

The above summary is not intended to constitute a complete analysis of all tax considerations applicable to U.S. Holders with respect to the acquisition, ownership, and disposition of Unit Shares, Warrants or Warrant Shares. U.S. Holders should consult their own tax advisors as to the tax considerations applicable to them in their own particular circumstances.

RISK FACTORS

An investment in the Units offered hereby involves certain risks. You should carefully consider, in light of your own financial circumstances, the risk factors set out below which relate to the Units, as well as the risk factors described under the heading "Risk Factors" found in the Annual Information Form, the Annual MD&A, the Interim MD&A, and the Prospectus (at pages 20 to 25). In addition, you should carefully consider all other information contained in this Prospectus Supplement, the Prospectus, the documents incorporated by reference herein and therein (including, without limitation, the Annual Information Form, the Annual MD&A and the Interim MD&A), and in all subsequently filed documents incorporated by reference, before making an investment decision.

S-23

Management of the Corporation will have broad discretion with respect to the application of a portion of the net proceeds received by the Corporation from the sale of Units under this Prospectus Supplement.

Management of the Corporation may spend a portion of net proceeds received by the Corporation from a sale of Units, if any, in ways that do not improve the Corporation's results of operations or enhance the value of the Units or its other securities issued and outstanding from time to time. Any failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Corporation's business or cause the market price of the securities of the Corporation issued and outstanding from time to time to decline.

The Corporation may sell additional Common Shares or other securities that are convertible or exchangeable into Common Shares in subsequent offerings or may issue additional Common Shares or other securities, resulting in dilution to investors.

The Corporation cannot predict the size or nature of future sales or issuances of securities or the effect, if any, that such future sales and issuances will have on the market price of the Common Shares. Such sales or issuances may occur for any number of reasons, including to strengthen the balance sheet of the Corporation or in connection with growth, acquisitions or strategic opportunities that may be available to the Corporation. Sales or issuances of substantial numbers of Common Shares or other securities that are convertible or exchangeable into Common Shares, or the perception that such sales or issuances could occur, may adversely affect prevailing market prices of the Common Shares. With any additional sale or issuance of Common Shares or other securities that are convertible or exchangeable into Common Shares, investors will suffer dilution to their voting power and economic interest in the Corporation. Furthermore, to the extent holders of the Corporation's stock options or other convertible securities convert or exercise their securities and sell the Common Shares they receive, the market price of the Common Shares may decrease due to the increased number of Common Shares available in the market.

The market price for the Common Shares may be volatile and subject to wide fluctuations in response to numerous factors, many of which are beyond the Corporation's control.

The market price of our Common Shares has in the past been, and may in the future be, subject to large fluctuations which may result in losses for investors. The factors which may contribute to market price fluctuations of the Common Shares include the following:

•actual or anticipated fluctuations in the Corporation's quarterly results of operations;

•local or international regulatory and political changes affecting the Corporation's industry generally and its business and operations;

•recommendations by securities research analysts;

•changes in the economic performance or market valuations of companies in the industry in which the Corporation operates;

•addition or departure of the Corporation's executive officers and other key personnel;

•release or expiration of transfer restrictions on outstanding Common Shares;

•sales or perceived sales of additional Common Shares;

•operating and financial performance that vary from the expectations of management, securities analysts and investors;

•announcements of developments and other material events by the Corporation or its competitors;

S-24

•fluctuations to the costs or availability of vital production materials and services;

•changes in global financial markets and global economies and general market conditions, such as interest rates;

•significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving the Corporation or its competitors;

•operating and share price performance of other companies that investors deem comparable to the Corporation;

•news reports relating to trends, concerns, technological or competitive developments, regulatory changes and other related issues in the Corporation's industry or target markets or in the economy generally; and

•the number of Common Shares sold on any one day in the aggregate pursuant to the Offering.

Following the consummation of the Offering, the Corporation's directors and executive officers will be subject to a [90-day] lock-up period provided under lock-up agreements to be executed in connection with the Offering. All of the Common Shares subject to the lock-up agreements will, however, be able to be resold after the expiration of the lock-up period, as well as pursuant to customary exceptions thereto or upon the waiver of the lock-up agreements.

The Corporation has not declared or paid dividends in the past and may not declare or pay dividends in the future.

Any decision to declare or pay dividends in the future will be made at the discretion of the Board and will depend on, among other things, financial results, cash requirements, contractual restrictions and other factors that the Board may deem relevant. As a result, investors may not receive any return on an investment in the Units unless they sell their Units (or the securities underlying the Units) for a price greater than that which such investors paid for them (including the exercise price paid for the acquisition of any Warrants Shares).

Negative cash flow from operations

During the thirteen months ended September 30, 2023, the Corporation had negative cash flow from operating activities. During the three months ended December 31, 2023, the Corporation generated positive cash flow from operating activities, however the Corporation cannot guarantee it will have a cash flow positive position in the future. To the extent that the Corporation has negative cash flow in any future period, certain of the proceeds from its offerings may be used to fund such negative cash flow from operating activities.

Market for Warrants

There is currently no market through which the Warrants may be sold. The Corporation does not plan to apply to list the Warrants on the TSX, NASDAQ or any other securities exchange or other trading system. There can be no assurance that an active or liquid trading market will develop for the Warrants after the Offering, or if developed, that such a market will be sustained. If an active or liquid market for the Warrants fails to develop or be sustained, the prices at which the Warrants trade may be adversely affected. The market price of the Warrants will be based on a number of factors, including but not limited to: (i) the markets for similar securities; (ii) the financial condition, results of operations and prospectus of the Corporation; (iii) the market price and volatility of the Common Shares; (iv) changes in the industry in which the Corporation operates and competition affecting the Corporation; and (v) general market and economic conditions. Purchasers may not be able to resell Warrants purchased under this Prospectus Supplement and the accompanying Prospectus. This may affect the pricing of the Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of these securities and the extent of issuer regulation.

Return on investment risk

There is no guarantee that an investment in the Unit Shares or Warrants comprising the Units will earn any positive return in the short or long term. No dividends on the Common Shares have been paid to date. A purchase of Units under the Offering involves a high degree of risk and should be undertaken only by investors whose financial resources are sufficient to enable them to assume such risks and who have no need for immediate liquidity in their investment.

S-25

Unknown health impact of use of cannabis and derivatives

There is little in the way of longitudinal studies on the short-term and long-term effects of cannabis use on human health, whether used for recreational or medicinal purposes. As such, there are inherent risks associated with using the Corporation's cannabis and derivative products. Previously unknown or unforeseeable adverse reactions arising from human consumption of cannabis products may occur which could adverse affect social acceptance of cannabis and the demand for the Corporation's products.

Enforcement of judgments against foreign persons may not be possible

Canadian investors should be aware that each of the Non-Resident Persons resides outside of Canada; as a result, it may not be possible for purchasers of the Units to effect service of process within Canada upon the Non-Resident Persons. All or a substantial portion of the assets of each of the Non-Resident Persons are likely to be located outside of Canada and, as a result, it may not be possible to satisfy a judgment against the Non-Resident Persons in Canada or to enforce a judgment obtained in Canadian courts against the Non-Resident Persons outside of Canada.

LEGAL MATTERS AND INTEREST OF EXPERTS

Certain legal matters relating to this Offering will be passed upon on our behalf by Goodmans LLP, with respect to certain legal matters relating to Canadian law, McMillan LLP, with respect to certain legal matters relating to U.S. law, and by Hodgson Russ LLP, with respect to certain matters relating to U.S. federal income tax law, and on behalf of the Underwriters, Dentons Canada LLP, with respect to certain legal matters relating to Canadian law. At the date hereof, partners and associates of each of Goodmans LLP, Hodgson Russ LLP and Dentons Canada LLP own beneficially, directly or indirectly, less than 1% of any of our securities or any securities of our associates or affiliates.

S-26

No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise.

Organigram Holdings Inc. (the "Corporation", "we", "our" or "us") may from time to time offer and issue the following securities: (a) common shares in the capital of the Corporation ("Common Shares"); (b) debentures, notes or other evidence of indebtedness of any kind, nature or description and which may be issuable in series (collectively, "Debt Securities"); (c) subscription receipts of the Corporation exchangeable for Common Shares and/or other securities of the Corporation ("Subscription Receipts"); (d) warrants exercisable to acquire Common Shares and/or other securities of the Corporation ("Warrants"); and (e) securities comprised of more than one of Common Shares, Debt Securities, Subscription Receipts and/or Warrants offered together as a unit ("Units"), or any combination thereof, up to an aggregate offering price of $500,000,000 (or the equivalent thereof, at the date of issue, in any other currency or currencies, as the case may be) at any time during the 25-month period that this short form base shelf prospectus (including any amendments hereto, the "Prospectus") remains valid. The Common Shares, Debt Securities, Subscription Receipts, Warrants and Units (collectively, the "Securities", and each, a "Security") offered hereby may be offered separately or together, in separate series, in amounts, at prices and on terms to be set forth in one or more prospectus supplements (collectively or individually, as the case may be, "Prospectus Supplements"). One or more holders of Common Shares ("Shareholders") may also offer Common Shares beneficially owned by them under this Prospectus. See "Selling Shareholders".

All shelf information permitted under applicable securities legislation to be omitted from this Prospectus including, without limitation, the information disclosed in the specific terms of any offering of Securities, as discussed above, will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus, except in cases where an exemption from such delivery requirements has been obtained. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of such Prospectus Supplement and only for the purposes of the distribution of the Securities to which that Prospectus Supplement pertains.

The Corporation is a Canadian issuer that is permitted, under a multi-jurisdictional disclosure system (the "MJDS") adopted by the securities regulatory authorities in Canada and the United States, to prepare this Prospectus and any Prospectus Supplement in accordance with Canadian disclosure requirements. Prospective investors in the United States should be aware that such requirements are different from those of the United States. Financial statements included or incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and may not be comparable to financial statements of United States companies prepared in accordance with US generally accepted accounting principles.

The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely because the Corporation is a corporation existing under the laws of Canada. The Corporation exists under the laws of Canada, and all of its executive offices, administrative activities and assets are located outside the United States. In addition, most of the directors and officers of the Corporation are residents of jurisdictions other than the United States and all or a substantial portion of the assets of those persons are or may be located outside the United States. See "Enforceability of Civil Liabilities".

NEITHER THE SECURITIES AND EXCHANGE COMMISSION (THE "SEC"), ANY STATE SECURITIES REGULATOR, NOR ANY CANADIAN SECURITIES REGULATOR HAS APPROVED OR DISAPPROVED OF THE SECURITIES OFFERED HEREBY OR PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

You should be aware that the acquisition of the Securities described herein may have tax consequences both in the United States and in Canada. Such tax consequences for investors who are residents in, or citizens of, the United States may not be described fully herein or in any applicable Prospectus Supplement. You should read the tax discussion in any applicable Prospectus Supplement; however, this Prospectus or any applicable Prospectus Supplement may not fully describe these tax consequences, and you should consult your tax advisor prior to making any investment in the Securities.

The specific terms of any offering of Securities will be set forth in the applicable Prospectus Supplement and may include, without limitation, where applicable: (a) in the case of Common Shares, the number of Common Shares being offered, the currency (which may be Canadian dollars or any other currency), the offering price (in the event the offering is a fixed price distribution) or the manner of determining the offering price(s) (in the event the offering is not a fixed price distribution) and any other specific terms; (b) in the case of Debt Securities, the specific designation, aggregate principal amount, the currency or the currency unit for which the Debt Securities may be purchased (which may be Canadian dollars or any other currency), maturity, interest provisions, authorized denominations, offering price, covenants, events of default, any terms for redemption at the option of the Corporation or the holder, any exchange or conversion terms and any other specific terms; (c) in the case of Subscription Receipts, the number of Subscription Receipts being offered, the currency (which may be Canadian dollars or any other currency), the offering price, the terms, conditions and procedures for the exchange of the Subscription Receipts into or for Common Shares and/or other securities of the Corporation and any other specific terms; (d) in the case of Warrants, the number of such Warrants offered, the currency (which may be Canadian dollars or any other currency), the offering price, the terms, conditions and procedures for the exercise of such Warrants into or for Common Shares and/or other securities of the Corporation and any other specific terms; and (e) in the case of Units, the number of Units being offered, the currency (which may be Canadian dollars or any other currency), the offering price, the terms of the Common Shares, Debt Securities, Subscription Receipts and/or Warrants, as the case may be, underlying the Units, and any other specific terms. A Prospectus Supplement relating to a particular offering of Securities may include terms pertaining to the Securities being offered thereunder that are not within the terms and parameters described in this Prospectus. Where required by statute, regulation or policy, and where the Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to the Securities will be included in the Prospectus Supplement describing the Securities.

The Corporation and/or any selling Shareholders may sell the Securities to or through one or more underwriters or dealers purchasing as principals and may also sell the Securities to one or more purchasers directly, through applicable statutory exemptions, or through one or more agents designated by the Corporation and/or any selling Shareholders from time to time. The Securities may be sold from time to time in one or more transactions at fixed prices or not at fixed prices, such as market prices prevailing at the time of sale, prices related to such prevailing market prices or prices to be negotiated with purchasers, which prices may vary as between purchasers and during the period of distribution of the Securities. The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent engaged in connection with the offering and sale of such Securities, as well as the method of distribution and the terms of the offering of such Securities, including the initial offering price (in the event the offering is a fixed price distribution), the manner of determining the offering price(s) (in the event the offering is not a fixed price distribution), the net proceeds to the Corporation and/or any selling Shareholders and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms. See "Plan of Distribution".

This Prospectus may qualify an “at-the-market distribution” by the Corporation as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”) of the Canadian Securities Administrators.

In connection with any offering of the Securities other than an "at-the-market distribution" (as defined under applicable Canadian legislation) (unless otherwise specified in the relevant Prospectus Supplement), the underwriters, dealers or agents may, subject to applicable law, over-allot or effect transactions that stabilize or maintain the market price of the offered Securities at a level above that which might otherwise prevail on the open market. Such transactions, if commenced, may be interrupted or discontinued at any time. See "Plan of Distribution". No underwriter or dealer involved in an "at-the-market distribution" under this Prospectus, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such underwriter or dealer will over-allot securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities.

The outstanding Common Shares are listed and posted for trading on the Toronto Stock Exchange (the “TSX”) and the Nasdaq Global Select Market (the “NASDAQ”) under the symbol “OGI”. On October 5, 2023, the last trading day prior to the date of this Prospectus, the closing price of the outstanding Common Shares on the TSX and NASDAQ was $1.60 and US$1.19, respectively.

Owning the Securities may subject you to tax consequences. This Prospectus and any applicable Prospectus Supplement may not describe the tax consequences fully. You should read the tax discussion in any applicable Prospectus Supplement and consult with your own tax advisor with respect to your own particular circumstances.

Unless otherwise specified in the applicable Prospectus Supplement, the Debt Securities, Subscription Receipts, Warrants and Units will not be listed on any securities exchange. There is no market through which these securities may be sold and purchasers may not be able to resell such securities purchased under this Prospectus. This may affect the pricing of such securities in the secondary market, the transparency and availability of trading prices, the liquidity of such securities, and the extent of issuer regulation. See "Forward-Looking Statements" and "Risk Factors".

The Corporation is continued under the Canada Business Corporations Act ("CBCA"). The head office of the Corporation is 145 King Street West, Suite 1400, Toronto, Ontario, Canada, M5H 1J8, and the registered office is at 35 English Drive, Moncton, New Brunswick, Canada, E1E 3X3.

No underwriter, agent or dealer has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.

Any investment in Securities involves significant risks that should be carefully considered by prospective investors before purchasing Securities. The risks outlined in this Prospectus and in the documents incorporated by reference herein, including the applicable Prospectus Supplement, should be carefully reviewed and considered by prospective investors in connection with any investment in Securities. See "Risk Factors".

FORWARD-LOOKING STATEMENTS

This Prospectus, including the documents incorporated by reference herein, contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "U.S. Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "U.S. Exchange Act") and "forward-looking information" as defined under applicable Canadian securities laws (collectively, "forward-looking statements"). All statements other than statements of historical fact contained in this Prospectus, or in the documents incorporated by reference herein, are forward-looking statements, including, without limitation, the Corporation's statements regarding the Corporation's business and the environment in which it operates, the intention of the Corporation to complete any offering of Securities on the terms and conditions described herein and in any Prospectus Supplement, the listing of any Securities, and the intention of the Corporation to use the MJDS to offer Securities in the United States. In certain cases, forward-looking statements can be identified by the use of words such as "plans", "expects", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", "projects" or "believes", "pro forma" or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will", "occur" or "be achieved" and similar words or the negative thereof. Although management of the Corporation believes that the expectations represented in such forward-looking statements are reasonable, there can be no assurance that such expectations will prove to be correct.

1

The forward-looking statements in this Prospectus are based on certain assumptions, including assumptions regarding present and future business strategies and the environment in which the Corporation will operate in the future, including expected revenues and ability to achieve goals. They are not guarantees of future performance and involve risks and uncertainties that are difficult to control or predict. A number of factors could cause actual results to differ materially from the results discussed in the forward-looking statements, including, but not limited to, the factors discussed under the heading "Risk Factors" in this Prospectus and in the Corporation's Annual Information Form (as defined herein) available electronically under the Corporation's System for Electronic Document Analysis and Retrieval + ("SEDAR+") profile at www.sedarplus.ca and on the United States Securities and Exchange Commission ("SEC") website at http://www.sec.gov.

There can be no assurance that forward-looking statements will prove to be accurate as actual outcomes and results may differ materially from those expressed in these forward-looking statements. Readers, therefore, should not place undue reliance on any such forward-looking statements. Further, these forward-looking statements are made as of the date of this Prospectus and, except as expressly required by applicable law, the Corporation assumes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

ADDITIONAL INFORMATION

We have filed with the SEC pursuant to MJDS a registration statement on Form F-10 under the U.S. Securities Act, relating to the Securities. This Prospectus, including the documents incorporated by reference into this Prospectus, which forms a part of the registration statement, does not contain all of the information contained in the registration statement, certain items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC. See "Documents Filed as Part of the Registration Statement". Statements included or incorporated by reference in this Prospectus about the contents of any contract, agreement or other documents referred to are not necessarily complete, and in each instance, you should refer to the exhibits to the registration statement for a complete description of the matter involved. Each such statement is qualified in its entirety by such reference. Each time we sell Securities under the registration statement, we will provide a Prospectus Supplement that will contain specific information about the terms of that offering. The Prospectus Supplement may also add, update or change information contained in this Prospectus.

The Corporation's Common Shares are registered under Section 12(b) of the U.S. Exchange Act and accordingly, we are subject to informational requirements of the U.S. Exchange Act and applicable Canadian requirements. In accordance with these informational requirements, we file reports and other information with the SEC and with securities regulatory authorities in Canada. Under the MJDS adopted by the United States and Canada, documents and other information that we file with the SEC may be prepared in accordance with the disclosure requirements of Canada, which are different from those of the United States.

As a foreign private issuer, we are exempt from the rules under the U.S. Exchange Act prescribing the furnishing and content of proxy statements, and our officers, directors and principal Shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the U.S. Exchange Act.

We file annual reports on Form 40-F with the SEC under the MJDS, which annual reports include:

• the annual information form;

• management’s annual discussion and analysis of financial condition and results of operations;

• consolidated audited financial statements, which are prepared in accordance with IFRS, as issued by the IASB; and

• other information specified by the Form 40-F.

2

As a foreign private issuer, we are required to furnish the following types of information to the SEC under cover of Form 6-K:

• material information that the Corporation otherwise makes publicly available in reports that the Corporation files with securities regulatory authorities in Canada;

• material information that the Corporation files with, and which is made public by, the TSX and NASDAQ; and

• material information that the Corporation distributes to its shareholders in Canada.

Reports and other information filed by us with, or furnished to, the SEC may be accessed on the SEC's website at www.sec.gov. You may read and download any public document that we have filed with the securities commission or similar regulatory authority in each of the provinces and territories of Canada, on SEDAR+ at www.sedarplus.ca.

ENFORCEABILITY OF CIVIL LIABILITIES

The Corporation exists under the laws of Canada, and all of its executive offices, administrative activities and assets are located outside the United States. In addition, most of the directors and officers of the Corporation are residents of jurisdictions other than the United States and all or a substantial portion of the assets of those persons are or may be located outside the United States.

As a result, investors who reside in the United States may have difficulty serving legal process in the United States upon the Corporation or its directors or officers, as applicable, or enforcing judgments obtained in United States courts against any of them or the assets of any of them located outside the United States, or enforcing against them in the appropriate Canadian court judgments obtained in United States courts, including, but not limited to, judgments predicated upon the civil liability provisions of the federal securities laws of the United States, or bringing an original action in the appropriate Canadian courts to enforce liabilities against the Corporation or any of its directors or officers, as applicable, based upon United States federal securities laws.

In the United States, the Corporation has filed with the SEC, concurrently with the filing of its registration statement on Form F-10, an appointment of agent for service of process on Form F-X. Under such Form F-X, the Corporation has appointed Corporation Service Company of 1090 Vermont Avenue N.W., Washington, D.C., 20005, U.S.A., as its agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against the Corporation in a U.S. court arising out of or related to or concerning the offering of the Securities under the registration statement.

Each Common Share entitles the holder thereof to receive notice of any meetings of Shareholders of the Corporation, to attend and to cast one vote at all such meetings. Holders of Common Shares do not have cumulative voting rights with respect to the election of directors and, accordingly, holders of a majority of the Common Shares entitled to vote in any election of directors may elect all directors standing for election. The holders of Common Shares are entitled to receive if, as and when declared by the Board, dividends in such amounts as shall be determined by the Board in its discretion. The holders of Common Shares have the right to receive the Corporation's remaining property and assets after payment of debts and other liabilities on a pro rata basis in the event of a liquidation, dissolution or winding-up, whether voluntary or involuntary. The Common Shares do not carry any pre-emptive, subscription, redemption or conversion rights, nor do they contain any sinking or purchase fund provisions.

The aggregate number of Common Shares which may be issued is unlimited and, as of October 5, 2023, the last trading day prior to the date of this Prospectus, there are 80,520,224 Common Shares outstanding.

Debt Securities

The Corporation may issue Debt Securities in one or more series under an indenture (the "Indenture"), to be entered into between the Corporation and a trustee. To the extent applicable, the Indenture will be subject to and governed by the United States Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). A copy of the form of the Indenture has been filed with the SEC as an exhibit to the registration statement on Form F-10 of which this Prospectus forms a part. The following description sets forth certain general material terms and provisions of the Debt Securities. If Debt Securities are issued, we will describe in the applicable Prospectus Supplement the particular material terms and provisions of any series of the Debt Securities and a description of how the general material terms and provisions described below may apply to that series of the Debt Securities. Prospective investors should read both the Prospectus and the Prospectus Supplement for a complete summary of all material terms relating to a particular series of Debt Securities. Prospective investors should be aware that information in the applicable Prospectus Supplement may update, amend and supersede the following information regarding the general material terms and provisions of the Debt Securities. Prospective investors also should refer to the Indenture, as it may be supplemented, for a complete description of all terms relating to the Debt Securities. We will file as exhibits to the registration statement, of which this Prospectus is a part, or will incorporate by reference from a report on Form 6-K that the Corporation furnishes to the SEC, any supplemental indenture describing the terms and conditions of Debt Securities that we are offering before the issuance of such Debt Securities. We will also file the final Indenture for any offering of Debt Securities on SEDAR+.

7

We may issue Debt Securities and incur additional indebtedness other than through the offering of Debt Securities pursuant to this Prospectus.

General

The Indenture will not limit the aggregate principal amount of Debt Securities that we may issue under the Indenture and will not limit the amount of other indebtedness that we may incur. The Indenture will provide that we may issue Debt Securities from time to time in one or more series and may be denominated and payable in U.S. dollars, Canadian dollars or any foreign currency. Unless otherwise indicated in the applicable Prospectus Supplement, the Debt Securities will be unsecured obligations of the Corporation. The Indenture will also permit us to increase the principal amount of any series of the Debt Securities previously issued and to issue that increased principal amount.

The applicable Prospectus Supplement for any series of Debt Securities that we offer will describe the specific terms of the Debt Securities and may include, but is not limited to, any of the following:

•the title of the Debt Securities;

•any limit on the aggregate principal amount of the Debt Securities and, if no limit is specified, the Corporation will have the right to re-open such series for the issuance of additional Debt Securities from time to time;

•the extent and manner, if any, to which payment on or in respect of the Debt Securities of the series will be senior or will be subordinated to the prior payment of other liabilities and obligations;

•whether payment of the Debt Securities will be guaranteed by any other person;

•whether or not the Debt Securities will be secured or unsecured, and the terms of any secured debt including a general description of the collateral and of the material terms of any related security, pledge or other agreement;

•the date or dates, or the method by which such date or dates will be determined or extended, on which the principal (and premium, if any) of the Debt Securities of the series is payable;

•the rate or rates at which the Securities of the series shall bear interest, if any, or the method by which such rate or rates shall be determined, whether such interest shall be payable in cash or additional Securities of the same series or shall accrue and increase the aggregate principal amount outstanding of such series, the date or dates from which such interest shall accrue, or the method by which such date or dates shall be determined;

•the place or places where we will pay principal, premium and interest, if any, and the place or places where Debt Securities can be presented for registration of transfer, exchange or conversion;

•whether and under what circumstances we will be required to pay any additional amounts for withholding or deduction for taxes with respect to the Debt Securities, and whether and on what terms we will have the option to redeem the Debt Securities rather than pay the additional amounts;

•whether we will be obligated to redeem, repay or repurchase the Debt Securities pursuant to any sinking or other provision, or at the option of a holder and the terms and conditions of such redemption, repayment or repurchase;

•whether we may redeem the Debt Securities, in whole or in part, prior to maturity and the terms and conditions of any such redemption;

8

•the denominations in which we will issue any registered Debt Securities, if other than denominations of US$2,000 and any multiple of US$1,000 and, if other than denominations of US$5,000, the denominations in which any unregistered Debt Security shall be issuable;

•whether we will make payments on the Debt Securities in a currency other than U.S. dollars;

•whether payments on the Debt Securities will be payable with reference to any index, formula or other method;

•whether we will issue the Debt Securities as global securities and, if so, the identity of the depositary for the global securities;

•whether we will issue the Debt Securities as unregistered securities, registered securities or both;

•any changes or additions to, or deletions of, events of default or covenants whether or not such events of default or covenants are consistent with the events of default or covenants in the Indenture;

•the applicability of, and any changes or additions to, the provisions for defeasance described under "Defeasance" below;

•whether the holders of any series of Debt Securities have special rights if specified events occur;

•the terms, if any, for any conversion or exchange of the Debt Securities for any other securities of the Corporation;

•provisions as to modification, amendment or variation of any rights or terms attaching to the Debt Securities; and

•any other terms, conditions, rights and preferences (or limitations on such rights and preferences).

Unless stated otherwise in the applicable Prospectus Supplement, no holder of Debt Securities will have the right to require us to repurchase the Debt Securities and there will be no increase in the interest rate if we become involved in a highly leveraged transaction or if we have a change of control.

We may issue Debt Securities bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, and we may offer and sell the Debt Securities at a discount below their stated principal amount. We may also sell any of the Debt Securities for a foreign currency or currency unit, and payments on the Debt Securities may be payable in a foreign currency or currency unit. In any of these cases, we will describe certain Canadian federal and U.S. federal income tax consequences and other special considerations in the applicable Prospectus Supplement.

We may issue Debt Securities with terms different from those of Debt Securities previously issued and, without the consent of the holders thereof, we may reopen a previous issue of a series of Debt Securities and issue additional Debt Securities of such series (unless the reopening was restricted when such series was created).

Guarantees

Our payment obligations under any series of Debt Securities may be guaranteed by certain of our direct or indirect subsidiaries. In order to comply with certain registration statement form requirements under U.S. law, these guarantees may in turn be guaranteed by the Corporation. The terms of such guarantees will be set forth in the applicable Prospectus Supplement.

9

Ranking and Other Indebtedness

Unless otherwise indicated in an applicable Prospectus Supplement, and except to the extent prescribed by law, each series of Debt Securities shall be senior, unsubordinated and unsecured obligations of the Corporation and shall rank pari passu and ratably without preference among themselves and pari passu with all other senior, unsubordinated and unsecured obligations of the Corporation.

Our Board may establish the extent and manner, if any, to which payment on or in respect of a series of Debt Securities will be senior, senior subordinated or subordinated to the prior payment of the Corporation's other liabilities and obligations, and whether the payment of principal, premium, if any, and interest, if any, will be guaranteed by any other person and the nature and priority of any security.

Debt Securities in Global Form

The Depositary and Book-Entry

Unless otherwise specified in the applicable Prospectus Supplement, a series of the Debt Securities may be issued in whole or in part in global form as a "global security" and will be registered in the name of or issued in bearer form and be deposited with a depositary, or its nominee, each of which will be identified in the applicable Prospectus Supplement relating to that series. Unless and until exchanged, in whole or in part, for the Debt Securities in definitive registered form, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of the depositary, by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any such nominee to a successor of the depositary or a nominee of the successor.

The specific terms of the depositary arrangement with respect to any portion of a particular series of the Debt Securities to be represented by a global security will be described in the applicable Prospectus Supplement relating to such series. The Corporation anticipates that the provisions described in this section will apply to all depositary arrangements.

Upon the issuance of a global security, the depositary therefor or its nominee will credit, on its book entry and registration system, the respective principal amounts of the Debt Securities represented by the global security to the accounts of such persons, designated as "participants", having accounts with such depositary or its nominee. Such accounts shall be designated by the underwriters, dealers or agents participating in the distribution of the Debt Securities or by the Corporation if such Debt Securities are offered and sold directly by the Corporation. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold beneficial interests through participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary therefor or its nominee (with respect to interests of participants) or by participants or persons that hold through participants (with respect to interests of persons other than participants). The laws of some states in the United States may require that certain purchasers of securities take physical delivery of such securities in definitive form.

So long as the depositary for a global security or its nominee is the registered owner of the global security or holder of a global security in bearer form, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the Debt Securities represented by the global security for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have a series of the Debt Securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of such series of the Debt Securities in definitive form and will not be considered the owners or holders thereof under the Indenture.

Any payments of principal, premium, if any, and interest, if any, on global securities registered in the name of a depositary or securities registrar will be made to the depositary or its nominee, as the case may be, as the registered owner of the global security representing such Debt Securities. None of the Corporation, any trustee or any paying agent for the Debt Securities represented by the global securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

10

The Corporation expects that the depositary for a global security or its nominee, upon receipt of any payment of principal, premium, if any, or interest, if any, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of such depositary or its nominee. The Corporation also expects that payments by participants to owners of beneficial interests in a global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in "street name", and will be the responsibility of such participants.

Discontinuance of Depositary's Services

If a depositary for a global security representing a particular series of the Debt Securities is at any time unwilling or unable to continue as depositary or, if at any time the depositary for such series shall no longer be registered or in good standing under the U.S. Exchange Act, and a successor depositary is not appointed by us within 90 days, the Corporation will issue such series of the Debt Securities in definitive form in exchange for a global security representing such series of the Debt Securities. If an event of default under the Indenture has occurred and is continuing, Debt Securities in definitive form will be printed and delivered upon written request by the holder to the appropriate trustee. In addition, the Corporation may at any time and in the Corporation's sole discretion determine not to have a series of the Debt Securities represented by a global security and, in such event, will issue a series of the Debt Securities in definitive form in exchange for all of the global securities representing that series of Debt Securities.

Debt Securities in Definitive Form

A series of the Debt Securities may be issued in definitive form, solely as registered securities, solely as unregistered securities or as both registered securities and unregistered securities. Registered securities will be issuable in denominations of US$2,000 and integral multiples of US$1,000 and unregistered securities will be issuable in denominations of US$5,000 and integral multiples of US$5,000 or, in each case, in such other denominations as may be set out in the terms of the Debt Securities of any particular series. Unless otherwise indicated in the applicable Prospectus Supplement, unregistered securities will have interest coupons attached.

Unless otherwise indicated in the applicable Prospectus Supplement, payment of principal, premium, if any, and interest, if any, on the Debt Securities in definitive form will be made at the office or agency designated by the Corporation, or at the Corporation's option the Corporation can pay principal, interest, if any, and premium, if any, by cheque mailed to the address of the person entitled at the address appearing in the security register of the trustee or electronic funds wire transfer to an account of persons who meet certain thresholds set out in the Indenture who are entitled to receive payments by wire transfer. Unless otherwise indicated in the applicable Prospectus Supplement, payment of interest, if any, will be made to the persons in whose name the Debt Securities are registered at the close of business on the day or days specified by the Corporation.

At the option of the holder of Debt Securities, registered securities of any series will be exchangeable for other registered securities of the same series, of any authorized denomination and of a like aggregate principal amount. If, but only if, provided in an applicable Prospectus Supplement, unregistered securities (with all unmatured coupons, except as provided below, and all matured coupons in default) of any series may be exchanged for registered securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. In such event, unregistered securities surrendered in a permitted exchange for registered securities between a regular record date or a special record date and the relevant date for payment of interest shall be surrendered without the coupon relating to such date for payment of interest, and interest will not be payable on such date for payment of interest in respect of the registered security issued in exchange for such unregistered security, but will be payable only to the holder of such coupon when due in accordance with the terms of the Indenture. Unless otherwise specified in an applicable Prospectus Supplement, unregistered securities will not be issued in exchange for registered securities.

11

The applicable Prospectus Supplement may indicate the places to register a transfer of the Debt Securities in definitive form. Service charges may be payable by the holder for any registration of transfer or exchange of the Debt Securities in definitive form, and the Corporation may, in certain instances, require a sum sufficient to cover any tax or other governmental charges payable in connection with these transactions.

We shall not be required to:

•issue, register the transfer of or exchange any series of the Debt Securities in definitive form during a period beginning at the opening of 15 days before any selection of securities of that series of the Debt Securities to be redeemed and ending on the relevant date of notice of such redemption, as provided in the Indenture;

•register the transfer of or exchange any registered security in definitive form, or portion thereof, called for redemption, except the unredeemed portion of any registered security being redeemed in part;

•exchange any unregistered security called for redemption except to the extent that such unregistered security may be exchanged for a registered security of that series and like tenor; provided that such registered security will be simultaneously surrendered for redemption; or

•issue, register the transfer of or exchange any of the Debt Securities in definitive form which have been surrendered for repayment at the option of the holder, except the portion, if any, of such Debt Securities not to be so repaid.

Provision of Financial Information

To the extent the Indenture is governed by the Trust Indenture Act, the Corporation will file with the trustee:

(i)copies of annual reports on Form 20-F or 40-F, as applicable (or any successor form), containing audited financial statements and the other financial information required to be contained therein (or required in such successor form);

(ii)copies of reports on Form 6-K (or any successor form) containing unaudited financial statements and the other financial information which are required to be provided in quarterly reports under the laws of Canada or any province thereof;

(iii)copies of annual reports on Form 10-K (or any successor form) and quarterly reports on Form 10-Q (or any successor form), if the Corporation ceases to be eligible to use the SEC rules and forms available to foreign private issuers (as defined in Rule 3b-4 under the U.S. Exchange Act); and

(iv)copies of such other information, documents and reports (or copies of such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) which the Corporation may be required to file with or furnish to the SEC pursuant to Section 13 or Section 15(d) of the U.S. Exchange Act;

in each case within 15 days after such materials have been filed with or furnished to the SEC.

In the event that the Corporation ceases to be subject to the reporting requirements of Section 13 or 15(d) of the U.S. Exchange Act at a time the Indenture is governed by the Trust Indenture Act,

• it will voluntarily:

•continue to file with the SEC annual reports on Form 20-F or 40-F, as applicable (or any successor form); and

•continue to furnish to the SEC reports on Form 6-K (or any successor form) containing unaudited financial statements and the other financial information which, regardless of applicable requirements shall, at a minimum, contain such information required to be provided in quarterly reports under the laws of Canada or any province thereof to security holders of a corporation with securities listed on the TSX, whether or not the Corporation has any of its securities so listed; or

12

•file with the SEC annual reports on Form 10-K (or any successor form) and quarterly reports on Form 10-Q (or any successor form), if the Corporation ceases to be eligible to use the SEC rules and forms available to foreign private issuers (as defined in Rule 3b-4 under the U.S. Exchange Act);

•in each case within the period prescribed for filing the Form 20-F, Form 40-F, Form 10-K or Form 10Q, as applicable, or for furnishing the Form 6-K to the SEC; and

•file a copy of such materials with the trustee within 15 days of their submission to the SEC.

Events of Default

Unless otherwise specified in the applicable Prospectus Supplement relating to a particular series of Debt Securities, the following is a summary of events which will, with respect to any series of the Debt Securities, constitute an event of default under the Indenture with respect to the Debt Securities of that series:

• the Corporation fails to pay principal of or any premium on any Debt Security of that series when it is due and payable;

• the Corporation fails to pay interest payable on any Debt Security of that series when it becomes due and payable, and such default continues for 30 days;

• the Corporation fails to make any required sinking fund or analogous payment when due for that series of Debt Securities;

• the Corporation fails to observe or perform any of its covenants or agreements in the Indenture that affect or are applicable to the Debt Securities of that series for 90 days after written notice to the Corporation by the trustees or to the Corporation and the trustees by holders of at least 25% in aggregate principal amount of the outstanding Debt Securities of that series;

• certain events involving the Corporation's bankruptcy, insolvency or reorganization; and

• any other event of default provided for in that series of Debt Securities.

A default under one series of Debt Securities will not necessarily be a default under another series. A trustee may withhold notice to the holders of the Debt Securities of any default, except in the payment of principal or premium, if any, or interest, if any, if in good faith it considers it in the interests of the holders to do so and so advises the Corporation in writing.

If an event of default for any series of Debt Securities occurs and continues, a trustee or the holders of at least 25% in aggregate principal amount of the Debt Securities of that series may require the Corporation to repay immediately:

• the entire principal and interest of the Debt Securities of the series; or

• if the Debt Securities are discounted securities, that portion of the principal as is described in the applicable Prospectus Supplement.

If an event of default relates to events involving the Corporation's bankruptcy, insolvency or reorganization, the principal of all Debt Securities will become immediately due and payable without any action by the trustee or any holder.

13

Subject to certain conditions, the holders of a majority of the aggregate principal amount of the Debt Securities of the affected series can rescind and annul an accelerated payment requirement. If Debt Securities are discounted securities, the applicable Prospectus Supplement will contain provisions relating to the acceleration of maturity of a portion of the principal amount of the discounted securities upon the occurrence or continuance of an event of default.

Other than its duties in case of a default, a trustee is not obligated to exercise any of the rights or powers that it will have under the Indenture at the request or direction of any holders, unless the holders offer the trustee reasonable security or indemnity. If they provide this reasonable security or indemnity, the holders of a majority in aggregate principal amount of any series of Debt Securities may, subject to certain limitations, direct the time, method and place of conducting any proceeding for any remedy available to a trustee, or exercising any trust or power conferred upon a trustee, for any series of Debt Securities.

The Corporation will be required to furnish to the trustees a statement annually as to its compliance with all conditions and covenants under the Indenture and, if the Corporation is not in compliance, the Corporation must specify any defaults. The Corporation will also be required to notify the trustees as soon as practicable upon becoming aware of any event of default.

No holder of a Debt Security of any series will have any right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or a trustee, or for any other remedy, unless:

•the holder has previously given to the trustees written notice of a continuing event of default with respect to the Debt Securities of the affected series;

•the holders of at least 25% in principal amount of the outstanding Debt Securities of the series affected by an event of default have made a written request, and the holders have offered reasonable indemnity, to the trustees to institute a proceeding as trustees; and

•the trustees have failed to institute a proceeding, and have not received from the holders of a majority in aggregate principal amount of the outstanding Debt Securities of the series affected (or in the case of bankruptcy, insolvency or reorganization, all series outstanding) by an event of default a direction inconsistent with the request, within 60 days after receipt of the holders' notice, request and offer of indemnity.

However, such above-mentioned limitations do not apply to a suit instituted by the holder of a Debt Security for the enforcement of payment of the principal of or any premium, if any, or interest on such Debt Security on or after the applicable due date specified in such Debt Security.

Defeasance

When the Corporation uses the term "defeasance", it means discharge from its obligations with respect to any Debt Securities of or within a series under the Indenture. Unless otherwise specified in the applicable Prospectus Supplement, if the Corporation deposits with a trustee cash, government securities or a combination thereof sufficient to pay the principal, interest, if any, premium, if any, and any other sums due to the stated maturity date or a redemption date of the Debt Securities of a series, then at the Corporation's option:

•the Corporation will be discharged from the obligations with respect to the Debt Securities of that series; or

•the Corporation will no longer be under any obligation to comply with certain restrictive covenants under the Indenture and certain events of default will no longer apply to the Corporation.

If this happens, the holders of the Debt Securities of the affected series will not be entitled to the benefits of the Indenture except for registration of transfer and exchange of Debt Securities and the replacement of lost, stolen, destroyed or mutilated Debt Securities. These holders may look only to the deposited fund for payment on their Debt Securities.

14

To exercise the defeasance option, the Corporation must deliver to the trustee:

•an opinion of counsel in the United States to the effect that the holders of the outstanding Debt Securities of the affected series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of a defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance had not occurred;

•an opinion of counsel in Canada or a ruling from the Canada Revenue Agency to the effect that the holders of the outstanding Debt Securities of the affected series will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other tax purposes as a result of a defeasance and will be subject to Canadian federal, provincial or territorial income tax and other tax on the same amounts, in the same manner and at the same times as would have been the case had the defeasance not occurred; and

•a certificate of one of the Corporation's officers and an opinion of counsel, each stating that all conditions precedent provided for relating to defeasance have been complied with.

If the Corporation is to be discharged from its obligations with respect to the Debt Securities, and not just from the Corporation's covenants, the U.S. opinion must be based upon a ruling from or published by the United States Internal Revenue Service or a change in law to that effect.

In addition to the delivery of the opinions described above, the following conditions must be met before the Corporation may exercise its defeasance option:

•no event of default or event that, with the passing of time or the giving of notice, or both, shall constitute an event of default shall have occurred and be continuing for the Debt Securities of the affected series;

•the Corporation is not an "insolvent person" within the meaning of applicable bankruptcy and insolvency legislation; and

•other customary conditions precedent are satisfied.

Modification and Waiver

Modifications and amendments of the Indenture may be made by the Corporation and the trustees pursuant to one or more Supplemental Indentures (a "Supplemental Indenture") with the consent of the holders of at least a majority in aggregate principal amount of the outstanding Debt Securities of each series affected by the modification. However, without the consent of each holder affected, no such modification may:

•change the stated maturity of the principal, premium, if any, or any instalment of interest, if any, on any Debt Security;

•reduce the principal, premium, if any, or rate of interest, if any, or change any obligation of the Corporation to pay any additional amounts;

•reduce the amount of principal of a debt security payable upon acceleration of its maturity or the amount provable in bankruptcy;

•change the place or currency of any payment;

•affect the holder's right to require the Corporation to repurchase the Debt Securities at the holder's option;

15

•impair the right of the holders to institute a suit to enforce their rights to payment;

•adversely affect any conversion or exchange right related to a series of Debt Securities;

•reduce the percentage of Debt Securities required to modify the Indenture or to waive compliance with certain provisions of the Indenture; or

•reduce the percentage in principal amount of outstanding Debt Securities necessary to take certain actions.

The holders of at least a majority in principal amount of outstanding Debt Securities of any series may on behalf of the holders of all Debt Securities of that series waive, insofar as only that series is concerned, past defaults under the Indenture and compliance by the Corporation with certain restrictive provisions of the Indenture. However, these holders may not waive a default in any payment of principal, premium, if any, or interest on any Debt Security or compliance with a provision that cannot be modified without the consent of each holder affected.

The Corporation may modify the Indenture pursuant to a Supplemental Indenture without the consent of any holders of Debt Securities to:

•evidence its successor under the Indenture;

•add covenants of the Corporation or surrender any right or power of the Corporation for the benefit of holders;

•add events of default;

•provide for unregistered securities to become registered securities under the Indenture and make other such changes to unregistered securities that in each case do not materially and adversely affect the interests of holders of outstanding Debt Securities;

•establish the forms of the Debt Securities;

•appoint a successor trustee under the Indenture;

•add provisions to permit or facilitate the defeasance and discharge of the Debt Securities as long as there is no material adverse effect on the holders;

•cure any ambiguity, correct or supplement any defective or inconsistent provision or make any other provisions in each case that would not materially and adversely affect the interests of holders of outstanding Debt Securities, if any; or

•change or eliminate any provisions of the Indenture where such change takes effect when there are no Debt Securities outstanding which are entitled to the benefit of those provisions under the Indenture.

Governing Law

To the extent the Indenture is governed by the Trust Indenture Act, the Indenture and the Debt Securities will be governed by and construed in accordance with the laws of the State of New York.

The Trustee

The trustee under the Indenture or its affiliates may provide banking and other services to the Corporation in the ordinary course of its business.

16

The Indenture will contain certain limitations on the rights of the trustee, as long as it or any of its affiliates remains the Corporation's creditor, to obtain payment of claims in certain cases or to realize on certain property received on any claim as security or otherwise. The trustee and its affiliates will be permitted to engage in other transactions with the Corporation. If the trustee or any affiliate acquires any conflicting interest and a default occurs with respect to the Debt Securities, the trustee must eliminate the conflict or resign.

Resignation and Removal of Trustee

A trustee may resign or be removed with respect to one or more series of the Debt Securities and a successor trustee may be appointed to act with respect to such series.

Consent to Jurisdiction and Service

Under the Indenture and to the extent the Indenture is governed by the laws of New York, the Corporation will irrevocably appoint an authorized agent upon which process may be served in any suit, action or proceeding arising out of or relating to the Offered Debt Securities or the Indenture that may be instituted in any United States federal or New York state court located in the City of New York, and will submit to such non-exclusive jurisdiction.

Subscription Receipts

The Subscription Receipts may be issued under a subscription receipt agreement. Subscription Receipts may be offered separately or together with other Securities, as the case may be. The applicable Prospectus Supplement will include details of the subscription receipt agreement, if any, governing the Subscription Receipts being offered. The Corporation will file a copy of any subscription receipt agreement, if any, relating to an offering of Subscription Receipts with the relevant securities regulatory authorities in Canada after it has been entered into by the Corporation.

Each applicable Prospectus Supplement will set forth the terms and other information with respect to the Subscription Receipts being offered thereby, which may include, without limitation, the following (where applicable):

•the aggregate number of Subscription Receipts offered;

•the price at which the Subscription Receipts will be offered;

•the terms, conditions and procedures for the conversion of the Subscription Receipts into other Securities;

•the dates or periods during which the Subscription Receipts are convertible into other Securities;

•the designation, number and terms of the other Securities that may be exchanged upon conversion of each Subscription Receipt;

•the designation, number and terms of any other Securities with which the Subscription Receipts will be offered, if any, and the number of Subscription Receipts that will be offered with each Security;

•whether such Subscription Receipts are to be issued in registered form, "book-entry only" form, bearer form or in the form of temporary or permanent global securities and the basis of exchange, transfer and ownership thereof;

•terms applicable to the gross or net proceeds from the sale of the Subscription Receipts plus any interest earned thereon;

•certain material Canadian and United States tax consequences of owning the Subscription Receipts; and

17

•any other material terms and conditions of the Subscription Receipts.

Warrants

Each series of Warrants may be issued under a separate warrant indenture or warrant agency agreement to be entered into between the Corporation and one or more banks or trust companies acting as Warrant agent or may be issued as stand-alone certificates. Warrants may be offered separately or together with other Securities, as the case may be. The applicable Prospectus Supplement will include details of the Warrant agreements, if any, governing the Warrants being offered. The Warrant agent, if any, will be expected to act solely as the agent of the Corporation and will not assume a relationship of agency with any holders of Warrant certificates or beneficial owners of Warrants. A copy of any warrant indenture or any warrant agency agreement relating to an offering of Warrants will be filed by the Corporation with the relevant securities regulatory authorities in Canada after it has been entered into by the Corporation.

We will not offer Warrants for sale separately to any member of the public in Canada unless the offering is in connection with and forms part of the consideration for an acquisition or merger transaction or unless the prospectus supplement containing the specific terms of the Warrants to be offered separately is first approved for filing by the securities commissions or similar regulatory authorities in each of the provinces and territories of Canada where the Warrants will be offered for sale.

Each applicable Prospectus Supplement will set forth the terms and other information with respect to the Warrants being offered thereby, which may include, without limitation, the following (where applicable):

•the designation of the Warrants;

•the aggregate number of Warrants offered and the offering price;

•the aggregate number of Units offered;

•the price at which the Units will be offered;

•the designation, number and terms of the Securities comprising the Units;

SELLING SHAREHOLDERS

This Prospectus may also, from time to time, relate to the offering of Common Shares by way of a secondary offering by certain selling Shareholders. The terms under which the Common Shares will be offered by selling Shareholders will be described in the applicable Prospectus Supplement. To the extent that any selling Shareholder is resident outside of Canada, the selling Shareholder will file a non-issuer's submission to jurisdiction form with the corresponding Prospectus Supplement. The Prospectus Supplement for or including any offering of the Common Shares by selling Shareholders will include, without limitation, where applicable: (a) the names of the selling Shareholders; (b) the number of Common Shares owned, controlled or directed by each of the selling Shareholders; (c) the number of Common Shares being distributed for the account of each selling Shareholder; (d) the number of Common Shares to be owned, controlled or directed by the selling Shareholders whether the Common Shares are owned by the selling Shareholders both of record and beneficially, of record only or beneficially only; (e) if a selling Shareholder purchased any of the Common Shares held by it in the 24 months preceding the date of the applicable Prospectus Supplement, the date or dates the selling Shareholder acquired the Common Shares; and (f) if a selling Shareholder acquired the Common Shares held by it in the 12 months preceding the date of the applicable Prospectus Supplement, the cost thereof to the selling Shareholder in the aggregate on a per security basis.

PLAN OF DISTRIBUTION

The Corporation and/or any selling Shareholders may from time to time during the 25-month period that this Prospectus, including any amendments hereto, remains valid, offer for sale and issue up to an aggregate of $500,000,000 in Securities hereunder. The Corporation and/or any selling Shareholders may offer and sell the Securities to or through underwriters, agents, or dealers purchasing as principals, and may also sell directly to one or more purchasers or through agents or pursuant to applicable statutory exemptions.

19

The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent, as the case may be, engaged by the Corporation in connection with the offering and sale of the Securities, and will set forth the terms of the offering of such Securities, including, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents in connection with the offering, the method of distribution of the Securities, the initial issue price, the proceeds that the Corporation and/or any selling Shareholders will receive and any other material terms of the plan of distribution. Any initial offering price and discounts, concessions or commissions allowed or re-allowed or paid to dealers may be changed from time to time.

The Securities may be sold by the Corporation from time to time in one or more transactions at a fixed price or prices or at prices which may be changed or at market prices prevailing at the time of sale, at prices related to such prevailing prices or at negotiated prices, including sales in transactions that are deemed to be “at-the-market distributions” as defined in NI 44-102 of the Canadian Securities Administrators, and including sales made directly on the TSX, the NASDAQ or other existing trading markets for the Securities. Any such transactions that are deemed “at-the-market-distributions” will be subject to regulatory approval. NI 44-102 only permits “at-the-market distributions” of “equity securities” (as defined in National Instrument 41-101). As such, without first obtaining exemptive relief, only Common Shares may be sold pursuant to “at-the-market distributions”. No underwriter, dealer or agent, no affiliate of such an underwriter, dealer or agent and no person acting jointly or in concert with such an underwriter, dealer or agent involved in an “at-the-market distribution” will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities.

The price at which the Securities will be offered and sold may vary from purchaser to purchaser and during the period of distribution.

In connection with the sale of the Securities, underwriters, dealers or agents may receive compensation, including in the form of underwriters', dealers' or agents' fees, commissions or concessions. Underwriters, dealers and agents that participate in the distribution of the Securities may be deemed to be underwriters for the purposes of applicable Canadian securities legislation and any such compensation received by them from the Corporation and/or any selling Shareholders and any profit on the resale of the Securities by them may be deemed to be underwriting commissions. In connection with any offering of Securities, except as otherwise set out in a Prospectus Supplement relating to a particular offering of Securities and other than in relation to an "at-the-market" distribution, the underwriters, dealers or agents, as the case may be, may over-allot or effect transactions intended to fix, stabilize, maintain or otherwise affect the market price of the Securities at a level other than those which otherwise might prevail on the open market. Such transactions may be commenced, interrupted or discontinued at any time.

Underwriters, dealers or agents who participate in the distribution of the Securities may be entitled, under agreements to be entered into with the Corporation and/or any selling Shareholders, to indemnification by the Corporation against certain liabilities, including liabilities under Canadian securities legislation and the U.S. Securities Act, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. Such underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, the Corporation and/or any selling Shareholders in the ordinary course of business.

Unless otherwise specified in the applicable Prospectus Supplement, each series or issue of Securities (other than Common Shares) will be a new issue of Securities with no established trading market. Accordingly, there is currently no market through which the Securities (other than Common Shares) may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus and the applicable Prospectus Supplement. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. See "Risk Factors".

20

EARNINGS COVERAGE RATIOS

Earnings coverage ratios will be provided in the applicable Prospectus Supplement(s) with respect to any issuance and sale of Debt Securities pursuant to this Prospectus.

PRIOR SALES

The Corporation previously filed a base shelf prospectus on August 30, 2021 (the "2021 Prospectus"). All capital raising activities pursuant to the 2021 Prospectus have been completed. Information regarding prior sales of Securities within the previous 12-month period will be provided, as required, in a Prospectus Supplement with respect to the issuance of Securities pursuant to such Prospectus Supplement.

TRADING PRICE AND VOLUME

Information regarding trading price and volume of the Securities will be provided as required for all of the Corporation's issued and outstanding Securities that are listed on any securities exchange, as applicable, in each Prospectus Supplement.

CERTAIN CANADIAN AND UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The applicable Prospectus Supplement may describe certain Canadian federal income tax consequences to an investor acquiring any Securities offered thereunder, including, for investors who are non-residents of Canada, whether the payments of principal, interest or distributions, if any, on the Securities will be subject to Canadian non-resident withholding tax. The applicable Prospectus Supplement may also describe certain U.S. federal income tax consequences of the acquisition, ownership and disposition of any Securities offered thereunder by an initial investor who is a U.S. person (within the meaning of the U.S. Internal Revenue Code of 1986, as amended). Prospective investors should consult their own tax advisers prior to deciding to purchase any of the Securities.

RISK FACTORS

Before deciding to invest in any Securities, prospective investors of the Securities should consider carefully the risk factors and the other information contained and incorporated by reference in this Prospectus and the applicable Prospectus Supplement relating to a specific offering of Securities before purchasing the Securities, including those risks identified and discussed under the heading "Risk Factors" in the Annual Information Form, which is incorporated by reference herein. See "Documents Incorporated by Reference".

An investment in the Securities offered hereunder is speculative and involves a high degree of risk. Additional risks and uncertainties, including those that the Corporation is unaware of or that are currently deemed immaterial, may also become important factors that affect the Corporation and its business. If any such risks actually occur, the Corporation's business, financial condition and results of operations could be materially adversely affected. Prospective investors should carefully consider the risks below and in the Annual Information Form and the other information elsewhere in this Prospectus and the applicable Prospectus Supplement and consult with their professional advisers to assess any investment in the Corporation.

There is no guarantee that the Securities will earn any positive return in the short term or long term.

A holding of Securities is speculative and involves a high degree of risk and should be undertaken only by holders whose financial resources are sufficient to enable them to assume such risks and who have no need for immediate liquidity in their investment. A holding of Securities is appropriate only for holders who have the capacity to absorb a loss of some or all of their holdings.

21

Management of the Corporation will have broad discretion with respect to the application of net proceeds received by the Corporation from the sale of Securities under this Prospectus and a future Prospectus Supplement.

Management of the Corporation may spend net proceeds received by the Corporation from a sale of Securities in ways that do not improve the Corporation's results of operations or enhance the value of the Common Shares or its other securities issued and outstanding from time to time. Any failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Corporation's business or cause the price of the securities of the Corporation issued and outstanding from time to time to decline.

The Corporation may sell additional Common Shares or other Securities that are convertible or exchangeable into Common Shares in subsequent offerings or may issue additional Common Shares or other Securities to finance future acquisitions.

The Corporation cannot predict the size or nature of future sales or issuances of securities or the effect, if any, that such future sales and issuances will have on the market price of the Common Shares. Sales or issuances of substantial numbers of Common Shares or other Securities that are convertible or exchangeable into Common Shares, or the perception that such sales or issuances could occur, may adversely affect prevailing market prices of the Common Shares. With any additional sale or issuance of Common Shares or other Securities that are convertible or exchangeable into Common Shares, investors will suffer dilution to their voting power and economic interest in the Corporation. Furthermore, to the extent holders of the Corporation's stock options or other convertible securities convert or exercise their securities and sell the Common Shares they receive, the trading price of the Common Shares may decrease due to the additional amount of Common Shares available in the market.

The market price for the Common Shares may be volatile and subject to wide fluctuations in response to numerous factors, many of which are beyond the Corporation's control.

The factors which may contribute to market price fluctuations of the Common Shares include the following:

•actual or anticipated fluctuations in the Corporation's quarterly results of operations;

•recommendations by securities research analysts;

•changes in the economic performance or market valuations of companies in the industry in which the Corporation operates;

•addition or departure of the Corporation's executive officers and other key personnel;

•release or expiration of transfer restrictions on outstanding Common Shares;

•sales or perceived sales of additional Common Shares;

•operating and financial performance that vary from the expectations of management, securities analysts and investors;

•regulatory changes affecting the Corporation's industry generally and its business and operations;

•announcements of developments and other material events by the Corporation or its competitors;

•fluctuations to the costs of vital production materials and services;

•changes in global financial markets and global economies and general market conditions, such as interest rates and pharmaceutical product price volatility;

22

•significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving the Corporation or its competitors;

•operating and share price performance of other companies that investors deem comparable to the Corporation or from a lack of market comparable companies;

•news reports relating to trends, concerns, technological or competitive developments, regulatory changes and other related issues in the Corporation's industry or target markets; and

•current and future global economic, political and social conditions, including the COVID-19 pandemic.

The Corporation has not declared and paid dividends in the past and may not declare and pay dividends in the future.

Any decision to declare and pay dividends in the future will be made at the discretion of the Corporation's Board and will depend on, among other things, financial results, cash requirements, contractual restrictions and other factors that the Corporation's Board may deem relevant. As a result, investors may not receive any return on an investment in the Common Shares unless they sell their Common Shares for a price greater than that which such investors paid for them.

There is currently no market through which the Securities, other than the Common Shares, may be sold and, unless otherwise specified in the applicable Prospectus Supplement, none of the Debt Securities, Warrants, Subscription Receipts or Units will be listed on any securities or stock exchange.

As a consequence, purchasers may not be able to resell the Debt Securities, Warrants, Subscription Receipts or Units purchased under this Prospectus and any Prospectus Supplement. This may affect the pricing of the Securities, other than the Common Shares, in the secondary market, the transparency and availability of trading prices, the liquidity of these securities and the extent of issuer regulation. There can be no assurance that an active trading market for the Securities, other than the Common Shares, will develop or, if developed, that any such market, including for the Common Shares, will be sustained.

Shareholders of the Corporation may be unable to sell significant quantities of Common Shares into the public trading markets without a significant reduction in the price of their Common Shares, or at all. There can be no assurance that there will be sufficient liquidity of the Common Shares on the trading markets, or that the Corporation will continue to meet the listing requirements of the TSX or maintain the listing on the NASDAQ or any other public stock exchange.

Foreign Licensing Requirements.

The Corporation's ability to achieve its business objectives in foreign jurisdictions is contingent, in part, upon its compliance with regulatory requirements enacted by governmental authorities and the Corporation obtaining all regulatory approvals, where necessary, for the sale of its products. The Corporation cannot predict how long it will take to secure all appropriate regulatory approvals for its products, or the extent of testing and documentation that may be required by governmental authorities. The impact of the various compliance regimes, any delays in obtaining, or failure to obtain regulatory approvals may significantly delay or impact the development of markets, products and sales initiatives and could have a material adverse effect on the Corporation's business, financial condition, results of operations and prospects.

23

The Corporation continues to monitor developments and policies in the foreign jurisdictions in which it operates and assess the impact thereof to its operations; however, such developments cannot be accurately predicted and could have an adverse effect on the Corporation's business, financial condition and results of operations and prospects.

Adequacy of Internal Control over Financial Reporting.

Disclosure controls and procedures (“DC&P”) are intended to provide reasonable assurance that material information is gathered and reported to senior management to permit timely decisions regarding public disclosure. Internal controls over financial reporting (“ICFR”) are intended to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes with IFRS. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause the Corporation to fail to meet its reporting obligations. Maintaining effective internal controls is a continuous effort that requires the Corporation to anticipate and react to changes in the Corporation’s business and the economic and regulatory environments and to expend significant resources to manage a system of internal controls that is adequate to satisfy the Corporation’s reporting obligations as a public company.

The Corporation is required to provide representations in its annual and interim filings relating to the establishment and maintenance of DC&P and ICFR as defined in National Instrument 52-109 – Certification of Disclosure in Issuers’ Annual and Interim Filings (“NI 52-109”) and is required to evaluate ICFR in a manner that meets the standards of NI 52-109 in Canada.

The U.S. Sarbanes-Oxley Act 2002, as amended (the “U.S. Sarbanes-Oxley Act”), requires management to assess and report annually on the effectiveness of the Corporation’s ICFR and identify any material weaknesses in the Corporation’s ICFR.  In order to comply with section 404(b) of the U.S. Sarbanes-Oxley Act in relation to its annual report on Form 40-F under the U.S. Exchange Act, the Corporation’s independent registered public accounting firm must issue an annual attestation report addressing the effectiveness of the Corporation’s ICFR.

In accordance with NI 52-109 and Rule 13a-15 of the U.S. Exchange Act, management of the Corporation conducted an evaluation of the design and operation of the Corporation’s DC&P and ICFR as of August 31, 2022. Based on this evaluation, management concluded that the Corporation's DC&P and ICFR were not effective as of August 31, 2022, due to material weaknesses in internal control over ICFR that were previously identified but continue to exist.

KPMG LLP, the Corporation’s independent registered public accounting firm, also performed an “integrated audit”, encompassing an opinion on the fairness of presentation of the Corporation’s annual financial statements for the financial year ended August 31, 2022, as well as an opinion on the effectiveness of the Corporation’s ICFR. KPMG LLP audited the Corporation's annual financial statements for the financial year ended August 31, 2022 and issued an adverse report on the effectiveness of ICFR. The audit report on the effectiveness of ICFR as of August 31, 2022, expresses an opinion that the Corporation did not maintain effective ICFR as of August 31, 2022 because of the effect of the material weaknesses described therein on the achievement of the objectives of the control criteria and contains an explanatory paragraph stating that material weaknesses related to the following have been identified and included in management’s assessment of the Corporation’s ICFR as of August 31, 2022:

• An ineffective control environment resulting form an insufficient number of trained financial reporting and accounting, information technology (IT) and operational personnel with the appropriate skills and knowledge and with assigned responsibility and accountability related to the design, implementation and operation of ICFR.

• The insufficient number of personnel described above contributed to an ineffective risk assessment process necessary to identify all relevant risks of material misstatement and to evaluate the implications of relevant risks on its ICFR.

• An ineffective information and communication process resulting from (i) insufficient communication and internal control information, including objectives and responsibilities, such as delegation of authority; and (ii) ineffective general IT controls, ineffective controls related to complex spreadsheets, and ineffective controls over information from service organizations, resulting in insufficient controls to ensure the relevance, timeliness and quality of information used in control activities.

• As a consequence of the above, the Corporation had ineffective control activities related to the design, implementation and operation of process-level and financial statement close controls which had a pervasive impact on the Corporation’s ICFR.

24

KPMG LLP’s audit report on the effectiveness of the Corporation’s ICFR as of August 31, 2022 contains an explanatory paragraph stating that the Corporation acquired Laurentian Organic Inc. during its 2022 fiscal year and management excluded it from its assessment of the effectiveness of the Corporation’s ICFR as of August 31, 2022. KPMG LLP’s audit of the Corporation’s ICFR also excluded an evaluation of the ICFR of Laurentian Organic Inc.  KPMG LLP’s attestation report on the Corporation’s ICFR is included in the Corporation’s annual report on Form 40-F under the U.S. Exchange Act for the year ended August 31, 2022.

During the three months ended May 31, 2023, the Corporation substantially progressed the implementation of its ERP system, with the effective date of launch of the first phase of the ERP taking place on March 1, 2023 (the “ERP Implementation”). Management identified the ERP Implementation as a material change to the Corporation’s ICFR that has materially affected, or is likely to materially affect, the Corporation’s ICFR during the three months ended May 31, 2023. For further information regarding the Corporation’s ICFR, including the Corporation’s remediation plan of its ICFR, see “Disclosure Controls and Procedures and Internal Control over Financial Reporting” in the Corporation’s Interim MD&A.

The failure by the Corporation to maintain effective ICFR could result in the loss of investor confidence in the reliability of its financial statements, which in turn could harm the Corporation's business and negatively impact the trading price of its Common Shares. In addition, any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm the Corporation's operating results or cause it to fail to meet its reporting obligations.

There can be no assurance that the Corporation will be able to remediate any identified material weaknesses or maintain all the controls necessary for continued compliance, and there can be no assurance that the Corporation will be able to retain sufficient skilled finance and accounting personnel, especially in light of the increased demand for such personnel among publicly traded companies. Future acquisitions of companies may provide the Corporation with challenges in implementing the required processes, procedures and controls in its acquired operations. Acquired companies may not have disclosure controls and procedures or internal control over financial reporting that are as thorough or effective as those required by the securities laws currently applicable to the Corporation.

No evaluation can provide complete assurance that the Corporation’s ICFR will detect or uncover all failures of persons within the Corporation to disclose material information otherwise required to be reported. The effectiveness of the Corporation’s controls and procedures could also be limited by simple errors or faulty judgment. The challenges involved in implementing appropriate ICFR will likely increase with the Corporation’s plans for ongoing development of its business and this will require that the Corporation continue to improve its internal controls over financial reporting. Although the Corporation intends to devote substantial time and incur costs, as necessary, to ensure ongoing compliance, the Corporation cannot be certain that it will be successful in maintaining effective ICFR or complying with NI 52-109, Rule 13a-15 of the U.S. Exchange Act and the U.S. Sarbanes-Oxley Act.

The Corporation is a "foreign private issuer" within the meaning of the rules under the U.S. Exchange Act, and as such is exempt from certain provisions applicable to United States domestic public companies.

Because the Corporation is a "foreign private issuer" under the U.S. Exchange Act, it is exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including:

•the rules under the U.S. Exchange Act requiring the filing of quarterly reports on Form 10-Q or current reports on Form 8-K with the SEC;

25

•the sections of the U.S. Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the U.S. Exchange Act;

•the sections of the U.S. Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and

•the selective disclosure rules by issuers of material non-public information under Regulation FD.

The Corporation is required to file an annual report on Form 40-F with the United States Securities and Exchange Commission within three months of the end of each fiscal year. The Corporation does not intend to voluntarily file annual reports on Form 10-K and quarterly reports on Form 10-Q in lieu of Form 40-F requirements. For so long as the Corporation chooses to only comply with foreign private issuer requirements, the information it is required to file with or furnish to the SEC will be less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information which would be made available to you if you were investing in a U.S. domestic issuer.

The Debt Securities may be unsecured and will rank equally in right of payment with all of our other future unsecured debt.

The Debt Securities may be unsecured and will rank equally in right of payment with all of our other existing and future unsecured debt. The Debt Securities may be effectively subordinated to all of our existing and future secured debt to the extent of the assets securing such debt. If we are involved in any bankruptcy, dissolution, liquidation or reorganization, the secured debt holders would, to the extent of the value of the assets securing the secured debt, be paid before the holders of unsecured debt securities, including the debt securities. In that event, a holder of Debt Securities may not be able to recover any principal or interest due to it under the Debt Securities.

In addition, the collateral, if any, and all proceeds therefrom, securing any Debt Securities may be subject to higher priority liens in favour of other lenders and other secured parties which may mean that, at any time that any obligations that are secured by higher ranking liens remain outstanding, actions that may be taken in respect of the collateral (including the ability to commence enforcement proceedings against the collateral and to control the conduct of such proceedings) may be at the direction of the holders of such indebtedness.

Negative cash flow from operations.

During the year ended August 31, 2022, the Corporation had negative cash flow from operating activities. Although the Corporation anticipates it will have positive cash flow from operating activities in future periods, the Corporation cannot guarantee it will have a cash flow positive status in the future. To the extent that the Corporation has negative cash flow in any future period, certain of the proceeds from its offerings may be used to fund such negative cash flow from operating activities.

EXEMPTION FROM NATIONAL INSTRUMENT 44-102

Pursuant to a decision of the Autorité des marchés financiers dated September 11, 2023, the Corporation was granted a permanent exemption from the requirement to translate into French this Prospectus as well as the documents incorporated by reference therein and any Prospectus Supplement to be filed in relation to an "at-the-market" distribution. This exemption is granted on the condition that this Prospectus and any Prospectus Supplement (other than in relation to an "at-the-market" distribution) be translated into French if the Corporation offers Securities to Québec purchasers in connection with an offering other than in relation to an "at-the-market" distribution.

26

In addition, certain legal matters in connection with an offering and sale of Securities will be passed upon for any underwriters, dealers or agents by counsel to be designated at the time of such offering and sale by such underwriters, dealers or agents with respect to matters of Canadian and, if applicable, United States or other foreign law. As at the date hereof, the partners and associates of Goodmans LLP and McMillan LLP, as a group, own less than 1% of the outstanding securities of the Corporation.
