Amendment No. 1 dated December 19, 2025 to the Short Form Base Shelf Prospectus dated September 17, 2025
This short form prospectus is a base shelf prospectus. This short form base shelf prospectus dated September 17, 2025, as amended by this amendment, has been filed under legislation in each of the provinces and the territories of Canada that permits certain information about these securities to be determined after the short form prospectus dated September 17, 2025, as amended by this amendment, has become final and that permits the omission from the prospectus of that information. The legislation requires the delivery to purchasers of a prospectus supplement containing the omitted information within a specified period of time after agreeing to purchase any of these securities, except in cases where an exemption from such delivery requirements has been obtained.
No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise. The short form base shelf prospectus dated September 17, 2025, as amended by this amendment, constitutes a public offering of these securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such securities.
Information contained herein is subject to completion or amendment. A registration statement relating to these securities has been filed with the United States Securities and Exchange Commission (the "SEC"). These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. The prospectus shall not constitute an offer to sell or the solicitation of an offer to buy nor shall be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.
Information has been incorporated by reference in this short form base shelf prospectus from documents filed with securities commissions or similar authorities in Canada. Copies of the documents incorporated herein by reference may be obtained on request without charge from the Secretary of Cybin Inc. at 100 King Street West, Suite 5600, Toronto, Ontario M5X 1C9, telephone 1-866-292-4601, and are also available electronically at www.sedarplus.ca.

CYBIN INC.
$1,700,000,000
Common Shares
Warrants
Units
Debt Securities
Subscription Receipts
The short form base shelf prospectus dated September 17, 2025 (the "Prospectus") of Cybin Inc. (the "Corporation" or "Cybin") is hereby amended by this Amendment No. 1 to increase the aggregate amount of Securities that may be offered from time to time under the Prospectus from $800,000,000 to $1,700,000,000. Capitalized terms used but not otherwise defined in this Amendment No. 1 have the meanings ascribed thereto in the Prospectus.
The Corporation is a foreign private issuer under United States securities laws and is permitted under the multijurisdictional disclosure system adopted by the United States and Canada to prepare the Prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the United States. The Corporation has prepared its consolidated financial statements, included or incorporated herein by reference, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board and its consolidated financial
statements are subject to Canadian generally accepted auditing standards and auditor independence standards. As a result, they may not be comparable to financial statements of United States companies.
Prospective investors should be aware that the purchase of Securities may have tax consequences that may not be fully described in the Prospectus or in any Prospectus Supplement, and should carefully review the tax discussion, if any, in the applicable Prospectus Supplement and in any event consult with a tax advisor.
An investor's ability to enforce civil liabilities under the United States federal securities laws may be affected adversely because the Corporation is incorporated in Canada, the majority of its officers and directors named in the Prospectus are not residents of the United States, and some of the Corporation's assets and all or a substantial portion of the assets of such persons are located outside of the United States. See "Risk Factors – Enforcement of Civil Liabilities" in the Prospectus and in this Amendment No. 1.
See "Cautionary Note Regarding Forward-Looking Information" and "Risk Factors" beginning on pages 1 and 32 of the Prospectus, respectively, and the documents incorporated or deemed to be incorporated by reference therein and the applicable Prospectus Supplement, for a discussion of certain risks that you should consider in connection with an investment in these Securities.
NEITHER THE SEC NOR ANY CANADIAN SECURITIES REGULATOR, NOR ANY STATE SECURITIES REGULATOR, HAS APPROVED OR DISAPPROVED THE SECURITIES OFFERED HEREBY OR PASSED UPON THE ACCURACY OR ADEQUACY OF THE PROSPECTUS OR DETERMINED IF THE PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.
Specifically, the Prospectus is amended by deleting all references to “$800,000,000” contained on the face page of the Prospectus and substituting “$1,700,000,000” therefor. The first paragraph of the text on the face page of the Prospectus, as so amended, is deleted and replaced with the following:
"This short form base shelf prospectus ("Prospectus") relates to the offering for sale from time to time (each, an "Offering") by Cybin Inc. (the "Corporation" or "Cybin") during the 25-month period commencing on September 17, 2025, that this Prospectus, including any amendments thereto, remains valid, of up to $1,700,000,000 in the aggregate of: (i) common shares ("Common Shares") of the Corporation; (ii) warrants ("Warrants") to purchase other Securities (as defined below) of the Corporation; (iii) units ("Units") comprised of one or more of the other Securities, (iv) senior and subordinated unsecured debt securities (collectively, "Debt Securities"), including debt securities convertible or exchangeable into other securities of the Corporation, and (v) subscription receipts ("Subscription Receipts" and together with the Common Shares, Warrants, Units and Debt Securities, collectively referred to herein as the "Securities"). The Securities may be offered separately or together, in amounts, at prices and on terms determined based on market conditions at the time of the sale and as set forth in an accompanying prospectus supplement ("Prospectus Supplement"). In addition, one or more securityholders of the Corporation (each a "Selling Securityholder") may also offer and sell Securities under this Prospectus. See "Selling Securityholders".
The Prospectus is further amended by deleting the fourth paragraph on page iii of the Prospectus, and replacing it with the following:
"In determining that the Corporation has a reasonable expectation to distribute, during the 25-month period commencing on September 17, 2025 that this Prospectus, including any amendments hereto, remains valid, up to $1,700,000,000 in the aggregate of Securities, management of the Corporation has considered its ongoing contractual commitments amounting to (i) approximately $60,083,262 which will be used to qualify, in the United States pursuant to prospectus supplements to the Corporation's registration statement on Form F-10, the Common Shares issuable from time to time upon the exercise of certain Common Share purchase warrants issued by the Corporation on August 4, 2023 and November 14, 2023 in connection with unit offerings of the Corporation, and (ii) approximately $238,407,547 which will be used to qualify the periodic resale in the United States, pursuant to prospectus supplements to the Registration Statement (as defined below), by certain selling shareholders of previously issued Common Shares (collectively, the
2
"Commitment Amount"). Further, on October 31, 2025, the Corporation completed a registered direct offering of 22,277,750 Common Shares (the "Offered Shares") and, in lieu of Common Shares to certain investors, 4,605,500 pre-funded Common Share purchase warrants (the "Pre-Funded Warrants") at a price of US$6.51 per Common Share and US$6.50999 per Pre-Funded Warrant (the "Registered Direct Offering"). Each Offered Share and Pre-Funded Warrant was accompanied by 0.35 of one Common Share purchase warrant (each whole warrant, an "October Warrant" and, together with the Offered Shares and Pre-Funded Warrants, the "Offered Securities"). Each October Warrant is exercisable to acquire one Common Share at a price of US$8.14 per Common Share. The Corporation qualified the Offered Securities in the United States pursuant to a prospectus supplement dated October 28, 2025 to the Corporation's registration statement on Form F-10, as amended (File No. 333-289139) (the "Registration Statement"), which was initially filed with the SEC, under the U.S. Securities Act, on July 31, 2025, as amended on September 17, 2025 concurrent with the filing of this Prospectus. Approximately $351,208,916 has been used to qualify the Offered Securities. Given the Commitment Amount and the closing of the Registered Direct Offering, as of December 19, 2025, the Corporation will have approximately $1,050,300,275 available under the Prospectus, which management of the Corporation reasonably expects to distribute during the 25-month period commencing on September 17, 2025 that this Prospectus, including any amendments hereto, remains valid.¹
In addition, management of the Corporation has considered U.S. securities laws in connection with the registration of the Common Shares underlying Warrants issued pursuant to an Offering. The registration under the United States Securities Act of 1933, as amended (the "U.S. Securities Act") of the Common Shares underlying Warrants initially sold to, or for the account or benefit of, U.S. persons (as defined in Regulation S Under the U.S. Securities Act) or persons in the United States pursuant to exemptions from the registration requirements of the U.S. Securities Act, permits the selling securityholders named in the U.S. prospectus supplements to the Corporation's registration statement on Form F-10 to re-sell such Common Shares without restriction under the U.S. Securities Act. In the absence of such registration, re-sales of such Common Shares would be required to comply with an exemption or exclusion from the registration requirements of the U.S. Securities Act.
The Corporation's Registration Statement was filed with the SEC concurrent with the filing of this Prospectus, for the equivalent United States dollar value of this Prospectus, being US$1,234,209,379.99 (converted from $1,700,000,000 at an exchange rate of US$1.00=CAD$1.3774, which was the daily average exchange rate reported by the Bank of Canada on December 18, 2025).
The Prospectus is further amended by deleting the reference to “$800,000,000” contained in the first sentence of the first paragraph under the heading “Plan of Distribution” on page 31, so that such sentence, as so amended, reads as follows:
"The Corporation and the Selling Securityholders may from time to time during the 25-month period commencing on September 17, 2025, that this Prospectus, including any amendments and supplements hereto, remains valid, offer for sale and sell up to an aggregate of $1,700,000,000 in Securities hereunder. To the extent there are any Secondary Offerings, the aggregate amount of Securities that may be offered and sold by the Corporation hereunder shall be reduced by the aggregate amount of such Secondary Offerings."
The Prospectus is further amended by deleting the second paragraph under the section titled "Documents Incorporated by Reference" and replacing it with the following:
"The following documents of the Corporation filed with the securities commissions or similar authorities in Canada are incorporated by reference in this Prospectus:
- annual information form of the Corporation dated June 30, 2025, for the year ended March 31, 2025 (the "Annual Information Form");
¹ This is a forward-looking statement that involves material assumptions by the Corporation. There is no certainty as to the Corporation's ability to distribute securities or to raise additional funding to support operations. See "Risk Factors".

- the audited consolidated financial statements of the Corporation and the notes thereto as at and for the fiscal years ended March 31, 2025 and 2024, together with the auditor's report thereon;

- material change report dated July 9, 2025, relating to the private placement completed by the Corporation on June 30, 2025, of US$50,000,000 aggregate principal amount of unsecured convertible debentures, as amended and restated on August 12, 2025 (the "Convertible Debentures") issued to a single investor ("High Trail") pursuant to a securities purchase agreement, dated June 30, 2025, as amended on August 12, 2025 (the "Securities Purchase Agreement");
- material change report dated September 3, 2025, relating to senior leadership changes;
- material change report dated November 7, 2025, relating to the Registered Direct Offering of the Offered Securities; and
- management information circular of the Corporation dated July 14, 2025 relating to the annual meeting of shareholders of the Corporation held on August 18, 2025."
The Prospectus is further amended by deleting the section titled "Select Recent Developments" and replacing it with the following:
"Other than as set forth below and generally in this Prospectus or the documents incorporated by reference herein, there have been no material developments in the business of the Corporation since November 12, 2025, the date of the Interim Financial Statements and Interim MD&A.
On December 18, 2025, the Corporation announced that it will voluntarily transfer its U.S. stock exchange listing to the Nasdaq Global Market ("Nasdaq") from the NYSE American. The Corporation expects that its Common Shares will cease trading on the NYSE American at market close on January 4, 2026 and commence trading on the Nasdaq at market open on January 5, 2026. Concurrent with the commencement of trading on Nasdaq, the Corporation will no longer trade under the ticker symbol "CYBN" and instead will trade under the ticker symbol "HELP". The Corporation will continue to be listed on the CBOE Canada and will also trade under the new "HELP" ticker symbol commencing on January 5, 2026."
The Prospectus is further amended by deleting the section titled "Consolidated Capitalization" and replacing it with the following:
"Other than as disclosed herein and in the documents incorporated by reference in this Prospectus, there have been no material changes to the share and loan capitalization of the Corporation since the date of the Interim Financial Statements.
The following table sets forth the consolidated capitalization of the Corporation as at December 18, 2025, the date immediately before the date of this Prospectus. This table should be read in conjunction with the Interim Financial Statements and the related notes and the Interim MD&A that are incorporated by reference in this Prospectus. On September 19, 2024, the outstanding Common Shares were consolidated on the basis of one new Common Share for every 38 existing Common Shares (the "Consolidation"). All figures in the table below related to securities are represented on a post-Consolidation basis.
| Description of Capital | December 18, 2025 |
|---|---|
| Loans and Borrowings | Nil^{(1)} |
| Common Shares | 49,894,131 |
Stock options 4,171,897(2)
Restricted share units 4,164,440(3)
Common Share purchase warrants 12,205,334(4)
Pre-Funded Warrants 4,605,500(5)
Notes:
(1) On November 3, 2025, the Corporation used a portion of the net proceeds of the Registered Direct Offering to repay the remaining balance outstanding under the Convertible Debentures held by High Trail of US$20,150,000 and incurred early repayment fees of US$2,615,000, resulting in a total cash repayment of US$22,765,000.
(2) On November 14, 2025, options to purchase an aggregate of 48,240 Common Shares at an exercise price of $8.39 per Common Share were granted under the Corporation’s equity incentive plan (the “Equity Incentive Plan”).
(3) On November 3, 2025, 3,564,440 restricted share units were granted under the Equity Incentive Plan.
(4) For ease of reference, the Common Share purchase warrants are presented above on a post-Consolidation basis however, the total number of Common Share purchase warrants outstanding have not been consolidated. Rather, the exchange ratio was adjusted on the Consolidation such that the number of Common Shares underlying each Common Share purchase warrant was consolidated.
(5) The Pre-Funded Warrants were issued pursuant to the Registered Direct Offering.
The applicable Prospectus Supplement will describe any material changes, and the effect of such material changes, on the share and loan capitalization of the Corporation that will result from the issuance of Securities pursuant to each Prospectus Supplement.”
The Prospectus is further amended by deleting the section titled “Use of Proceeds” and replacing it with the following:
“The net proceeds from any Offering of Securities and the proposed use of those proceeds will be set forth in the applicable Prospectus Supplement relating to that Offering of Securities. Notwithstanding, the Corporation’s management has broad discretion in the application of proceeds of an Offering of Securities. On the basis of results obtained or for other sound business reasons, the Corporation may re-allocate funds as required. Accordingly, the Corporation’s actual use of proceeds may vary significantly from any proposed use of proceeds disclosed in any applicable Prospectus Supplement. See “Risk Factors – Risks Related to an Offering – Discretion over the Use of Proceeds”. The Corporation will not receive any proceeds from any sale of Securities by a Selling Securityholder.
Sources and Uses of Capital
As at December 19, 2025, the Corporation had approximately US$202,000,000 in cash. As at December 19, 2025, the Corporation anticipates that it will require approximately US$202,000,000 to continue operations over the next 12 months, including funding towards the achievement of the next significant milestone under the Corporation’s Deuterated Psilocin Program (CYB003), Deuterated Dimethyltryptamine Program (CYB004), and Phenethylamine and Tryptamine Derivatives Program (CYB005).
The Corporation may be required to reduce its general and administrative expenses if it does not have sufficient capital to meet its below stated objectives, or it may allocate its financial resources differently than listed below. The expected reduction in future expenditures, absent any capital injections, compared to the Corporation’s historic expenditures would be achieved as follows: (i) a reduction in marketing activities; (ii) a reduction in workforce and/or compensation; (iii) a reduction in public relations and investor relations activities; and (iv) a reduction of planned expenses under the Deuterated Dimethyltryptamine Program and Phenethylamine Derivatives Program, which would also result in a delay of anticipated timing for completion of the next significant milestones under each of these programs.
| Program(1) | Anticipated 12 Month Use of Funds(2)(3) US($) | Anticipated Timeline for Completion(4) |
|---|---|---|
| Deuterated Psilocin Program (CYB003)(5) | ||
| Provide topline efficacy data readout from the first Phase 3 study, APPROACH | 35,051,000 | Q4 2026 |

| Initiation of enrollment in the second Phase 3 study, EMBRACE | 399,000 | Q4 2025 |
|---|---|---|
| Progression of the second Phase 3 study, EMBRACE | 38,122,000 | N/A(7) |
| Progression of the third Phase 3 study, EXTEND | 25,995,000 | N/A(7) |
| Deuterated Dimethyltryptamine Program (CYB004) | ||
| Provide topline data readout from the Phase 2 GAD study | 1,339,000 | Q1 2026 |
| Phenethylamine and Tryptamine Derivatives Program (CYB005) | ||
| Deliver a drug development candidate | 1,404,000 | Q3 2026 |
| Working Capital, and General Corporate Purposes(6) | 99,690,000 | N/A |
| Total | 202,000,000 |
Notes:
(1) Please see the Interim MD&A for a description of the Corporation's programs. All milestones are subject to receipt of all necessary approvals, including the academic and scientific organizations with which the Corporation is working.
(2) Effective April 1, 2025, the Corporation changed its presentation currency from the Canadian dollar to the United States dollar. The change in presentation currency was made to better reflect the Corporation's operations, align with the currency in which the majority of cash based expenses are denominated, and improve comparability of its financial results with other publicly traded businesses in the industry. As a result, all amounts presented under the heading "Sources and Uses of Capital" are in United States dollar unless otherwise stated.
(3) Represents proceeds from private placements and offerings previously disclosed.
(4) Anticipated timeline for completion is based on the calendar year. There is no assurance that these timelines will be met or that the programs will advance. Drug development involves long lead times, is very expensive and involves many variables of uncertainty. Anticipated spending and timelines regarding drug development and recruitment of patients for participation in clinical trials are dependent on various factors and are based on reasonable assumptions informed by current knowledge and information available to the Corporation. Such statements are informed by, among other things, eligibility and exclusion criteria for the trial, design of the clinical trial, competition with other companies for clinical sites or patients, perceived risks and benefits of the prescription drug product candidate, the number, availability, location and accessibility of clinical trial sites, regulatory guidelines for developing a drug with safety studies, proof of concept studies, and pivotal studies for new drug application submission and approval, and assumes the success of implementation and results of such studies on timelines indicated as possible by such guidelines, other industry examples, and the Corporation's development efforts to date.
(5) The Corporation's APPROACH trial participants (n=220) will be randomized 1:1 to receive 16 mg of CYB003 (n=110), or inactive placebo (n=110). Each arm will evaluate a two-dose regimen, with doses administered three weeks apart. The study will enroll patients suffering from moderate to severe MDD (MADRS≥24) who are on a stable dose of antidepressant medication but are responding inadequately. The primary endpoint will be change in depressive symptoms as measured by change in MADRS from baseline at six weeks after the first dose. APPROACH is expected to enroll at approximately 45 clinical sites across the U.S. The Corporation's EMBRACE trial participants (n=330) will be randomized 1:1:1 to receive 16 mg of CYB003 (n=110), 8 mg of CYB003 (n=110), or inactive placebo (n=110). Each arm will evaluate a two-dose regimen, with doses administered three weeks apart. The study will enroll patients suffering from moderate to severe MDD (MADRS≥24) who are on a stable dose of antidepressant medication but are responding inadequately. The primary endpoint will be change in depressive symptoms as measured by change in MADRS from baseline at six weeks after the first dose. EMBRACE is expected to enroll at approximately 60 clinical sites, with minimal site overlap with the APPROACH study. Participants (up to n=550) from APPROACH and EMBRACE will roll over into EXTEND, the Corporation's Phase 3 Pivotal study 3 trial, after the completion of the 12-week, double-blind, placebo-controlled treatment periods. During EXTEND, all participants who did not respond to treatment in the APPROACH and EMBRACE studies or who relapse during the EXTEND study will be eligible to receive an additional two doses of CYB003 (16 mg) administered three weeks apart. Participants who do not respond to these two doses or relapse again will be eligible to receive an additional single 16 mg dose of CYB003. The Corporation has engaged Worldwide Clinical Trials Inc, a full-service contract research organization with deep expertise in central nervous system drug development, to carry out the Phase 3 pivotal studies of CYB003. The Corporation cannot at this time estimate the cost of bringing CYB003 drug candidate to market as much of the associated costs depend on the outcomes of the phase III pivotal clinical trials. Further, there is no assurance that the aforementioned timelines will be met or that such studies will be completed. Anticipated timelines regarding drug development and recruitment of patients for participation in clinical trials are dependent on various factors and are based on reasonable assumptions informed by current knowledge and information available to the Corporation. Such statements are informed by, among other things, eligibility and exclusion criteria for the trial, design of the clinical trial, competition with other companies for clinical sites or patients, perceived risks and benefits of the prescription drug product candidate, the number, availability, location and accessibility of clinical trial sites, regulatory guidelines for developing a drug with safety studies, proof of concept studies, and pivotal studies for new drug application submission and approval, and assumes the success of implementation and results of such studies on timelines indicated as possible by such guidelines, other industry examples, and the Corporation's development efforts to date.
(6) Includes personnel costs, professional services, overhead expenses and general expenses to be incurred by the Corporation in the normal course of business. In addition, the Corporation intends to use a portion of these proceeds to continue funding both its Deuterated Psilocin Program and Deuterated Dimethyltryptamine Program. The allocation between and specific milestones within these programs have not yet been determined.
(7) The Corporation will progress the Phase 3 study EMBRACE and Phase 3 study EXTEND over the next 12 months however, these studies are not anticipated to be completed within the 12 month timeframe.
For detailed information in respect of the Corporation’s business objectives and milestones, and the application of proceeds from prior offerings by the Corporation, prospective purchasers of Securities should carefully consider the information described in the Annual Information Form and Interim MD&A of the Corporation, and the documents incorporated by reference herein, including the applicable Prospectus Supplement.
As at December 19, 2025, the Corporation’s current financial resources, absent any capital injections, will be sufficient to meet the Corporation’s short-term liquidity requirements and to fund its operations for the coming 12 months. The Corporation makes this statement based on its current cash position of approximately US$202,000,000.
The Corporation’s expectation is based on certain assumptions and risks as set forth in the section “Cautionary Note Regarding Forward Looking Information” and “Risk Factors” in this Prospectus.
The expected uses of capital represents the Corporation’s current intentions based upon its present plans and business condition, which could change in the future as its plans and business conditions evolve. The amounts and timing of the actual use of available capital will depend on multiple factors and there may be circumstances where, for sound business reasons, a reallocation of capital, or termination of a program objective, may be necessary in order for the Corporation to achieve its program objectives. The Corporation may also require additional funds in order to fulfill its expenditure requirements to meet existing and any new business objectives, and the Corporation expects to either issue additional securities or incur debt to do so. The material factors or assumptions used to develop the estimated amounts for the 12 months period disclosed above are included in the “Cautionary Note Regarding Forward-Looking Information” section above. The actual amount that the Corporation spends in connection with each of the identified uses and programs will depend on a number of factors, including those listed under “Risk Factors” in, or incorporated by reference in, this Prospectus.
Negative Cash Flow From Operations
Since inception, the Corporation has financed its operations primarily from the issuance of equity and interest income on funds available for investment. To date, the Corporation has raised approximately US$537,755,000 in gross proceeds through private placement and prospectus offerings. The Corporation has experienced operating losses and cash outflows from operations since incorporation and will require ongoing financing to continue its research and development activates. As the Corporation has not yet achieved profitability. The Corporation has not earned any revenue or reached successful commercialization of any products. The Corporation’s success is dependent upon the ability to finance its cash requirements to continue its activities. There is no assurance that additional capital or other types of financing will be available if needed or that these financings will be on terms at least as favourable to the Corporation as those previously obtained, or at all. To the extent that the Corporation has negative operating cash flows in future periods, it may need to deploy a portion of its existing working capital to fund such negative cash flows. The Corporation will be required to raise additional funds through the issuance of additional equity securities, through loan financing, or other means, such as through partnerships with other companies and research and development reimbursements. There is no assurance that additional capital or other types of financing will be available if needed or that these financings will be on terms at least as favourable to the Corporation as those previously obtained. See “Risk Factors – Risks Related to an Offering - Negative Operating Cash Flow”.
The Prospectus must be read together with this amendment, any documents incorporated or deemed to be incorporated by reference therein from time to time and any supplements relating to an Offering of Securities thereunder. The statements contained in the Prospectus or in a document incorporated or deemed to be incorporated by reference therein on or subsequent to December 19, 2025, are modified or superseded for the purposes of this amendment to the extent that a statement contained in any subsequently filed document, which is also or is deemed to be incorporated by reference therein, modifies or superseded that statement.

RISK FACTORS
An investment in the Securities involves a high degree of risk and must be considered speculative due to the nature of the Corporation’s business and present stage of development. Before making an investment decision, prospective purchasers of Securities should carefully consider the information described in this Prospectus and the documents incorporated by reference herein, including the applicable Prospectus Supplement. There are certain risks inherent in an investment in the Securities, including the factors described below and under the heading “Risk Factors” in the Annual Information Form and in the Interim MD&A, and any other risk factors described herein or in a document incorporated by reference herein, which investors should carefully consider before investing. Additional risk factors relating to a specific Offering of Securities will be described in the applicable Prospectus Supplement. Some of the factors described herein, in the documents incorporated by reference herein, and/or the applicable Prospectus Supplement are interrelated and, consequently, investors should treat such risk factors as a whole. If any of the risk factors described herein, in the Annual Information Form, in another document incorporated by reference herein or in the applicable Prospectus Supplement occur, it could have a material adverse effect on the business, financial condition and results of operations of the Corporation. Additional risks and uncertainties of which the Corporation currently is unaware or that are unknown or that it currently deems to be immaterial could have a material adverse effect on the Corporation’s business, financial condition and results of operation. The Corporation cannot assure purchasers that it will successfully address any or all of these risks. There is no assurance that any risk management steps taken will avoid future loss due to the occurrence of the risks described herein, in the Annual Information Form, in the other documents incorporated by reference herein or in the applicable Prospectus Supplement or other unforeseen risks.
Enforcement of Civil Liabilities
Certain of the Corporation’s subsidiaries and assets are located outside of Canada. Accordingly, it may be difficult for investors to enforce within Canada any judgments obtained against the Corporation, including judgments predicated upon the civil liability provisions of applicable Canadian securities laws or otherwise. Consequently, investors may be effectively prevented from pursuing remedies against the Corporation under Canadian securities laws or otherwise.
The Corporation has subsidiaries incorporated in the United States. It may not be possible for shareholders to effect service of process outside of Canada against the directors and officers of the Corporation who are not resident in Canada. In the event a judgment is obtained in a Canadian court against one or more of such persons for violations of Canadian securities laws or otherwise, it may not be possible to enforce such judgment against persons not resident in Canada. Additionally, it may be difficult for an investor, or any other person or entity, to assert Canadian securities law or other claims in original actions instituted in the United States. Courts in such jurisdiction may refuse to hear a claim based on a violation of Canadian securities laws or otherwise on the grounds that such jurisdiction is not the most appropriate forum to bring such a claim. Even if a foreign court agrees to hear a claim, it may determine that the local law, and not Canadian law, is applicable to the claim. If Canadian law is found to be applicable, the content of applicable Canadian law must be proven as a fact, which can be a time-consuming and costly process. Certain matters of procedure will also be governed by foreign law.
Most of the officers and directors named in this Prospectus are not residents of the United States, and some of the Corporation’s assets and all or a substantial portion of the assets of such person are located outside of the United States.
The Corporation has been advised that, subject to certain limitations, a judgment of a United States court predicated solely upon civil liability under United States federal securities laws may be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. The Corporation has also been advised, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon United States federal securities laws or any such state securities or “blue sky” laws.
The Corporation is filing with the SEC, concurrently with the Registration Statement, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Corporation appointed C T Corporation System 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 or involving the Corporation in a United States court, arising out of or related to or concerning the offering of the Securities.
STATUTORY AND CONTRACTUAL RIGHTS OF WITHDRAWAL AND RESCISSION
Unless provided otherwise in a Prospectus Supplement, the following is a description of a purchaser's statutory rights. Securities legislation in certain of the provinces and territories of Canada provides purchasers of the Securities with the right to withdraw from an agreement to purchase the Securities, which right may be exercised within two business days after receipt or deemed receipt of the Prospectus, the accompanying Prospectus Supplement and any amendment relating to the Securities purchased by a purchaser. In several of the provinces and territories, the securities legislation further provides a purchaser with remedies for rescission or, in some jurisdictions, revisions of the price, or damages if the prospectus, prospectus supplement, and any amendment relating to securities purchased by a purchaser contains a misrepresentation or are not sent or delivered to the purchaser, provided that the remedies for rescission, revisions of the price or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province or territory. However, purchasers of Securities distributed under an "at-the-market distribution" do not have the right to withdraw from an agreement to purchase the Securities and do not have remedies of rescission or, in some jurisdictions, revisions of the price, or damages for non-delivery of the prospectus, prospectus supplement, and any amendment relating to Securities purchased by such purchaser because the prospectus, prospectus supplement, and any amendment relating to the Securities purchased by such purchaser will not be sent or delivered, as permitted under Part 9 of NI 44-102. Any remedies under securities legislation that a purchaser of the Securities distributed under an "at-the-market distribution" may have against the Corporation or its agents for rescission or, in some jurisdictions, revisions of the price, or damages if the prospectus, prospectus supplement, and any amendment relating to securities purchased by a purchaser contain a misrepresentation will remain unaffected by the non-delivery of the prospectus referred to above. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province or territory for the particulars of these rights or consult with a legal advisor.
Original purchasers of Securities under the Prospectus (as supplemented or amended) that are convertible, exchangeable or exercisable securities, will be granted a contractual right of rescission against the Corporation in respect of the conversion, exchange or exercise of such Securities. The contractual right of rescission will entitle such original purchasers to receive, in addition to the amount paid on original purchase of any Securities, the amount paid upon conversion, exchange or exercise, upon surrender of the underlying securities gained thereby, in the event that the Prospectus, (as supplemented or amended) contains a misrepresentation, provided that both the conversion, exchange or exercise occurs, and the right of rescission is exercised, within 180 days of the date of the purchase of the Securities under the Prospectus (as supplemented or amended). This contractual right of rescission will be consistent with the statutory right of rescission described under Section 130 of the Securities Act (Ontario) and is in addition to any other right or remedy available to original purchasers under Section 130 of the Securities Act (Ontario) or otherwise at law.
In an Offering of Securities, to the extent such securities are convertible, exchangeable or exercisable securities, investors are cautioned that the statutory right of action for damages for a misrepresentation contained in the Prospectus (as supplemented or amended) is limited, in certain provincial and territorial securities legislation, to the price at which the Securities are offered to the public under the prospectus offering. This means that, under the securities legislation of certain provinces and territories of Canada, if the purchaser pays additional amounts upon conversion, exchange or exercise, as applicable, of the Security, those amounts may not be recoverable under the statutory right of action for damages that applies in those provinces and territories of Canada. The purchaser should refer to any applicable provisions of applicable provincial or territorial securities legislation for the particulars of this right of action for damages or consult with a legal advisor.
