PRELIMINARY PROSPECTUS SUBJECT TO COMPLETION DATED DECEMBER 23, 2025

Up to 2,793,296 Common Units, Each Consisting of a Common Share and a Warrant to Purchase One Common Share

Up to 2,793,296 Pre-funded Units, Each Consisting of a Pre-funded Warrant to Purchase One Common Share and a Warrant to Purchase One Common Share

Up to 2,793,296 Common Shares included in the Common Units

Up to 2,793,296 Warrants included in the Common Units and Pre-funded Units

Up to 2,793,296 Pre-funded Warrants included in the Pre-funded Units

Up to 2,793,296 Common Shares Underlying the Warrants

Up to 2,793,296 Common Shares Underlying the Pre-funded Warrants

BriaCell Therapeutics Corp.

We are offering on a best efforts basis (the “Offering”) up to 2,793,296 common units (each, a “Common Unit”) of BriaCell Therapeutics Corp. Each Common Unit consists of one common share, no par value per share (a “common share”), and one warrant (each a “Warrant”). Each Warrant will entitle the holder to purchase one common share at an exercise price of $11.1875, equal to 125% of the assumed public offering price of one Common Unit of $8.95 per Common Unit (which is the last reported sales price of our common shares on the Nasdaq Capital Market (“Nasdaq”) on December 19, 2025). Each Warrant will expire five years from date of issuance.

We are also offering to those purchasers, if any, whose purchase of Common Units in this Offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common shares immediately following the consummation of this Offering, the opportunity to purchase, if the purchaser so chooses, pre-funded units (each a “Pre-funded Unit”) in lieu of Common Units. Each Pre-funded Unit will consist of one pre-funded warrant to purchase one common share at an exercise price of $0.001 per share (each a “Pre-funded Warrant”) and one Warrant. Each Pre-funded Warrant will be immediately exercisable for one common share and will not expire prior to exercise. The purchase price of each Pre-funded Unit is equal to the price per Common Unit being sold to the public in this Offering, minus $0.001, and the exercise price of each Pre-funded Warrant will be $0.001 per share.

The common shares and Pre-funded Warrants can each be purchased in this Offering only with the accompanying Warrants that are part of a Common Unit or Pre-funded Unit, respectively, but the components of the Common Units and Pre-funded Units will be immediately separable and will be issued separately in this Offering. See “Description of Securities” in this prospectus for more information.

The Offering also includes the common shares issuable from time to time upon exercise of the Pre-funded Warrants and Warrants.

The Common Units, the Pre-funded Units and the Pre-funded Warrants will not be listed on Nasdaq or the Toronto Stock Exchange (“TSX”) and are not expected to trade in any market. We are also registering the common shares issuable upon exercise of the Warrants and Pre-funded Warrants pursuant to this prospectus.

This Offering will terminate on March 15, 2026, unless completed sooner or we decide to terminate the Offering (which we may do at any time in our discretion) prior to that date.

We will deliver all securities to be issued in connection with this Offering delivery versus payment/receipt versus payment upon receipt by us of investor funds. We will have one closing for all the securities purchased in this Offering. Accordingly, neither we nor the placement agent (as defined below) have made any arrangements to place investor funds in an escrow account or trust account since the placement agent will not receive investor funds in connection with the sale of the securities offered hereunder.

You should read this prospectus, together with additional information described under the heading “Where You Can Find More Information” carefully before you invest in any of our securities.

Our common shares are listed on Nasdaq and the TSX under the symbols “BCTX” and “BCT”, respectively, and our public warrants are listed on Nasdaq under the symbols “BCTXW” and “BCTXZ”. On December 22, 2025, the last reported sale price of our common shares on Nasdaq was $9.73 per share, the last reported sale price of our BCTXW public warrants on Nasdaq was $0.045 per warrant and the last reported sale price of our BCTXZ public warrants on Nasdaq was $0.39 per warrant. The actual public offering price per Common Unit sold in this Offering will be determined between us and the placement agent based on market conditions at the time of pricing and may be at a discount to the current market price. Therefore, the assumed public offering price used throughout this prospectus may not be indicative of the final offering price. We intend to apply to list the Warrants on Nasdaq under the symbol “BCTXX”. No assurance can be given that a trading market will develop for the Warrants. There is no established public trading market for the Pre-funded Warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the Pre-funded Warrants on any national securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Pre-funded Warrants will be limited.

We have engaged ThinkEquity LLC, or the placement agent, to act as our exclusive placement agent in connection with this Offering. The placement agent has agreed to use its reasonable best-efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number or dollar amount of securities. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus.

There is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum offering requirement as a condition of closing of this Offering. Because there is no minimum Offering amount required as a condition to closing this Offering, we may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this Offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue our business goals described in this prospectus. We will bear all costs associated with the Offering. See “Plan of Distribution” on page 22 of this prospectus for more information regarding these arrangements.

We are an “emerging growth company,” as defined under the federal securities laws and, as such, we have elected to comply with certain reduced public company reporting requirements for this prospectus and future filings. See “Prospectus Summary - Implications of Being an Emerging Growth Company and Smaller Reporting Company.”

Investing in our securities is speculative and involves a high degree of risk. You should carefully consider the risk factors beginning on page 7 of this prospectus before purchasing our securities. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The securities offered by this prospectus have not been and will not be qualified for sale under the securities laws of any province or territory of Canada or to any resident of Canada and may not be offered or sold, directly or indirectly, in Canada, or to or for the account of any resident of Canada. This prospectus has not been filed in respect of, and will not qualify, any distribution of these securities in any province or territory of Canada.

PROSPECTUS SUMMARY

The following summary highlights information contained or incorporated by reference elsewhere in this prospectus and does not contain all of the information that you should consider in making your investment decision. Before investing in our common shares, you should carefully read this entire prospectus, including our consolidated financial statements and the related notes and other documents incorporated by reference herein, as well as the information under the caption “Risk Factors” herein and under similar headings in the other documents that are incorporated by reference into this prospectus including documents that are filed after the date hereof. Some of the statements in this prospectus constitute forward-looking statements that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements.” Our actual results could differ materially from those anticipated in such forward-looking statements as a result of certain factors, including those discussed in the “Risk Factors” and other sections included in or incorporated by reference herein. In this prospectus, unless otherwise stated or the context otherwise requires, references to the “Company,” “we,” “our,” “BriaCell” and “us” refer to BriaCell Therapeutics Corp., and its subsidiaries, unless otherwise indicated or required by the context.

Overview

BriaCell Therapeutics Corp. (“Briacell” or the “Company”) is a clinical-stage biotechnology company that is developing novel immunotherapies to transform cancer care. Immunotherapies have come to the forefront in the fight against cancer as they harness the body’s own immune system to recognize and destroy cancer cells. The Company is currently advancing its Bria-IMT™ targeted immunotherapy in combination with an immune check point inhibitor (Retifanlimab) in a pivotal Phase 3 study in metastatic breast cancer. Bria-IMT™ is currently under Fast Track Designation by the U.S. Food and Drug Administration (the “FDA”) intended to accelerate the review process of novel treatments that address unmet medical needs. Positive completion of the pivotal study, following review by FDA, could lead to full approval of the Bria-IMT™ immune checkpoint inhibitor combination in metastatic breast cancer. BriaCell reported benchmark-beating patient survival and clinical benefit in metastatic breast cancer with median overall survival of 13.4 months in BriaCell’s metastatic breast cancer patients vs. 6.7-9.8 months for similar patients reported in the literature in its Phase 2 study of Bria-IMT™ combination study with retifanlimab at the 2023 San Antonio Breast Cancer Symposium. A completed Bria-IMT™ Phase 1 combination study with retifanlimab (an anti-PD1 antibody manufactured by Incyte) confirmed tolerability and early-stage efficacy. BriaCell is also developing personalized off-the-shelf immunotherapies, Bria-OTS™ and Bria-OTS+™, which provides a platform technology to develop personalized off-the-shelf immunotherapies for numerous types of cancer, and a soluble CD80 protein therapeutic which acts both as a stimulator of the immune system as well as an immune checkpoint inhibitor.

Recent Developments

On August 13, 2025, we announced acceptance into Memorial Sloan Kettering Cancer Center’s (MSK’s) 2025 Therapeutics Accelerator Cohort program for the Bria-OTS+™ platform, which includes the Bria-BRES+™ product candidate for breast cancer.

On August 25, 2025, we reported that we had been awarded a US$2.0 million Small Business Innovation Research (SBIR) grant from the U.S. National Cancer Institute (NCI) to advance Bria-PROS+™ in prostate cancer, providing non-dilutive funding to support manufacturing and planned clinical evaluation activities for this program

On October 21, 2025, we further announced a collaboration with MSK’s Therapeutics Accelerator program focused on the Bria-OTS+ platform. The collaboration includes support for manufacturing, IND development and clinical protocol work for a planned Phase 1 study of Bria-BRES+ in breast cancer, and is intended to help accelerate clinical development of Bria-OTS+ across multiple cancer indications.

We continued to advance our pivotal Phase 3 clinical study of Bria-IMT™ plus an immune checkpoint inhibitor (CPI) in metastatic breast cancer (MBC). On October 13, 2025, we announced plans to present positive biomarker data from this ongoing trial at the ESMO 2025 Congress, highlighting that biomarkers identified in our prior Phase 2 study showed similar trends in the Phase 3 setting, and that a delayed-type hypersensitivity response appeared to be associated with longer progression-free survival in a blinded analysis of Phase 3 patients, with no new safety or tolerability issues identified. On October 21, 2025, we reported that 79 clinical sites across 23 U.S. states were enrolling patients in the Phase 3 study, including new participation by Dartmouth Cancer Center, Cedars-Sinai Medical Center and Winship Cancer Institute of Emory University, and indicated that top-line data could be available as early as the first half of 2026, subject to event accrual. On October 22, 2025, we disclosed that the independent Data Safety Monitoring Board (DSMB) had issued a fourth consecutive positive recommendation following review of safety data from the Phase 3 trial, identifying no safety concerns and recommending that the study continue without modification; the trial is being conducted under U.S. FDA Fast Track designation.

We also expanded our clinical data-generation activities for Bria-IMT at major oncology conferences. In November and December 2025, we announced a series of forthcoming presentations at the 2025 San Antonio Breast Cancer Symposium (SABCS®). On November 18 and November 25, 2025, we reported that three BriaCell posters had been accepted, which together will present updated overall survival data from the Phase 2 study of Bria-IMT plus CPI in MBC and positive biomarker findings from the pivotal Phase 3 study. On December 2, 2025, we confirmed that these SABCS presentations, which occurred on December 10, 2025, highlighted survival and clinical benefit data from the Phase 2 program as well as key Phase 3 biomarker data, and reiterated that an interim overall survival analysis in the pivotal Phase 3 trial that is expected in the first half of 2026.

In parallel, we continued to develop our next-generation Bria-OTS+™ off-the-shelf cell-based immunotherapy platform. On October 3, 2025, we announced plans to present preclinical data on Bria-OTS+ at the Society for Immunotherapy of Cancer (SITC) 2025 Annual Meeting, followed on November 4, 2025 by a release describing a SITC poster to showcase anti-tumor activity of Bria-OTS+ in breast and prostate cancer models, and the ongoing GMP manufacturing of lead candidates Bria-BRES+ and Bria-PROS+ in preparation for clinical trials. On November 7, 2025, we reported preclinical results presented at SITC 2025 indicating that Bria-OTS+ induced rapid and durable anti-cancer activity in preclinical models by engaging both innate and adaptive immune responses, and that both Bria-BRES+ and Bria-PROS+ increased tumor cell cytotoxicity in these models.

Finally, we continued to broaden our pipeline beyond cell-based immunotherapies. On November 20, 2025, we announced a collaboration between our subsidiary BriaPro Therapeutics Corp. and Receptor.AI to apply Receptor.AI’s artificial intelligence platform to design highly selective anti-cancer kinase inhibitor candidates. The collaboration is intended to expand BriaPro’s small-molecule oncology pipeline and complements our existing cell-based programs, with the goal of accelerating development of next-generation cancer therapeutics with improved efficacy and safety profiles.

Implications of Being an Emerging Growth Company and Smaller Reporting Company

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As a result, we rely on exemptions from certain disclosure requirements that are applicable to other companies that are not emerging growth companies. Accordingly, we have included detailed compensation information for only our three most highly compensated executive officers and have not included a compensation discussion and analysis of our executive compensation programs in this prospectus. In addition, for so long as we are an “emerging growth company,” we will not be required to:

● engage an auditor to report on our internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002;

● comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

● comply with new or revised accounting standards applicable to public companies as quickly as other public companies;

● submit certain executive compensation matters to shareholder advisory votes, such as “say-on-pay,” “say-on-frequency,” and “say-on-golden parachutes;” or

● disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparison of the chief executive officer’s compensation to median employee compensation.

In addition, the JOBS Act provides that an “emerging growth company” can use the extended transition period for complying with new or revised accounting standards.

We will remain an “emerging growth company” until the earliest to occur of:

● our reporting $1.235 billion or more in annual gross revenues;

● our issuance, in a three-year period, of more than $1 billion in non-convertible debt;

● the end of the fiscal year in which the market value of our common shares held by non-affiliates exceeds $700 million on the last business day of our second fiscal quarter; and

● July 31, 2026.

We cannot predict if investors will find our securities less attractive because we may rely on these exemptions, which could result in a less active trading market for our securities and increased volatility in the price of our securities.

Finally, we are a “smaller reporting company” (and may continue to qualify as such even after we no longer qualify as an emerging growth company) and accordingly may provide less public disclosure than larger public companies, including the inclusion of only two years of audited financial statements and only two years of management’s discussion and analysis of financial condition and results of operations disclosure. As a result, the information that we provide to our shareholders may be different than you might receive from other public reporting companies in which you hold equity interests.

Share Consolidations

A one-for-15 consolidation of our issued and outstanding common shares became effective under the corporate law of British Columbia, Canada on January 24, 2025 and the post-consolidation common shares commenced trading on the TSX and Nasdaq on January 29, 2025. A one-for-10 consolidation of our issued and outstanding common shares became effective under the corporate law of British Columbia, Canada on August 25, 2025 and the post-consolidation common shares commenced trading on the TSX and Nasdaq on August 25, 2025.

THE OFFERING

Common Units offered by us	2,793,296 Common Units, each Common Unit consisting of one common share and one Warrant, with each Warrant exercisable for one common share. The Warrants offered as part of the Common Units are exercisable immediately, at an exercise price of $11.1875, equal to 125% of the assumed public offering price of $8.95 per Common Unit (which is the last reported sale price of our common shares on Nasdaq on December 19, 2025). The Warrants expire five years from the date of issuance. The securities contained in the Common Units are immediately separable and will be issued separately in this Offering. This prospectus also relates to the offering of the common shares issuable upon exercise of the Warrants.
Pre-funded Units offered by us	We are also offering to those purchasers, if any, whose purchase of Common Units in this Offering would otherwise result in such purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common shares immediately following the consummation of this Offering, the opportunity to purchase, if the purchaser so chooses, Pre-funded Units in lieu of Common Units.
	Each Pre-funded Unit will consist of a Pre-funded Warrant to purchase one common share at an exercise price of $0.001, per share and one Warrant. The purchase price of each Pre-funded Unit is equal to the price per Common Unit being sold to the public in this Offering, minus $0.001. The Pre-funded Warrants will be immediately exercisable and may be exercised at any time. For each Pre-funded Unit we sell, the number of Common Units we are offering will be decreased on a one-for-one basis.
	Because we will issue one Warrant as part of each Common Unit or Pre-funded Unit, the number of Warrants sold in this Offering will not change.
	This Prospectus also relates to the offering of the common shares issuable upon exercise of the Pre-funded Warrants.
Number of common shares outstanding immediately before this Offering	1,883,906 issued and outstanding as of December 19, 2025.
Number of common shares to be outstanding after this Offering(1)	4,677,202 shares, based on an assumed public offering price of $8.95 per share (which is the last reported sale price of our common shares on Nasdaq on December 19, 2025) and assumes no sale of Pre-funded Units, which, if sold, would reduce the number of common shares that we are offering on a one-for-one basis.
Use of proceeds	If we sell all of the securities offered hereby, we estimate that the net proceeds of this Offering based upon an assumed public offering price of $8.95 per Common Unit, and after deducting placement agent fees and estimated offering expenses, will be approximately $22.71 million, assuming no exercise of the Warrants. However, because this Offering is being made on a best-efforts basis, and there is no minimum offering amount required as a condition to the closing of this Offering, we may sell fewer than all of the securities offered hereby and may receive significantly less in net proceeds from this Offering. We currently intend to use the net proceeds from this Offering to fund working capital requirements, general corporate purposes and the advancement of business objectives. See “Use of Proceeds”.

Trading

Our common shares are listed on Nasdaq under the symbol “BCTX”. We intend to apply to list the Warrants on Nasdaq under the symbol “BCTXX”. No assurance can be given that a trading market will develop for the Warrants. There is no established public trading market for the Pre-funded Warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the Pre-funded Warrants on any national securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Pre-funded Warrants will be limited.

Risk Factors

Investing in our common shares involves a high degree of risk. See “Risk Factors” beginning on page 7 of this prospectus, and the other information included, or incorporated by reference, in this prospectus for a discussion of factors you should consider carefully before deciding to invest in our securities.

(1) The number of common shares to be outstanding following this Offering is based on 1,883,906 outstanding common shares as of December 19, 2025, and excludes:

● 1,681,606 common shares issuable upon the exercise of outstanding warrants, at a weighted average exercise price of $58.74;

● 50,951 common shares issuable upon the exercise of outstanding options, at a weighted average exercise price of $242.15;

● 40,000 common shares issuable upon the conversion of outstanding restricted share units, at a weighted average exercise price of $0.01; and

● 165,935 common shares issuable upon the conversion of outstanding performance share units, at a weighted average exercise price of $0.01.

Unless otherwise indicated, this prospectus also assumes no sale of Pre-funded Units and no exercise of the warrants to the placement agent (the “placement agent warrants”).

RISK FACTORS

Investing in our securities is highly speculative and involves a significant degree of risk. You should carefully consider the following risks and uncertainties as well as the risks and uncertainties described in the section entitled “Risk Factors” contained in our Annual Report on Form 10-K for the fiscal year ended July 31, 2025 (the “2025 Form 10-K”), as well as in our subsequent Quarterly and Annual Reports filed with the Securities and Exchange Commission (“SEC”), which filings are incorporated in this prospectus by reference in their entirety. These risk factors could materially and adversely affect our business, results of operations or financial condition. Our business faces significant risks and the risks described below or incorporated by reference herein may not be the only risks we face. Additional risks not presently known to us or that we currently believe are immaterial may materially affect our business, results of operations, or financial condition. If any of these risks occur, the trading price of our common shares could decline and you may lose all or part of your investment.

Risks Related to this Offering and Ownership of our Securities

If we are unable to maintain listing of our securities on Nasdaq, the TSX or any stock exchange, our share price could be adversely affected and the liquidity of our common shares and our ability to obtain financing could be impaired and it may be more difficult for our shareholders to sell their securities.

Although our common shares are currently listed on Nasdaq and the TSX, we may not be able to continue to meet Nasdaq’s minimum listing requirements or those of any other national exchange. If we are unable to maintain listing of our common shares on Nasdaq or the TSX or if a liquid market for our common shares does not develop or is not sustained, our common shares may remain thinly traded.

On July 3, 2024, the Company received a letter from the Listing Qualifications Department of Nasdaq indicating that, based upon the Company’s market value of listed securities (“MVLS”) for the 33 consecutive business days from May 15, 2024, to July 2, 2024, the Company did not meet the minimum MVLS of $35,000,000, $2.5 million shareholders’ equity or $500,000 of net income from continuing operations requirements for The Nasdaq Capital Market set forth in Listing Rules 5550(b)(2), 5550(b)(1), or 5550(b)(3) (the “Rules”) required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(2). The letter also indicated that the Company would be provided with a compliance period of 180 calendar days, or until December 30, 2024, in which to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(C).

On December 18, 2024, we received a letter from the Listing Qualifications Department of Nasdaq notifying the Company that based on our shareholders’ equity, we comply with the Rules and the matter is now closed.

In addition, on August 22, 2024, the Company received a letter from the Nasdaq Listing Qualifications Department notifying the Company that, for the last 30 consecutive business days, the closing bid price for the Company’s common shares have been below the minimum $1.00 per share required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). The Company regained compliance with the Minimum Bid Price Requirement on February 12, 2025.

Under amended Nasdaq Listing Rule 5810(c)(3)(A)(iv) (the “Nasdaq Excessive Reverse Stock Split Rule”), companies are now limited by how many times they can effect reverse stock splits within a certain time period to regain compliance with the minimum bid price requirement. Under the Nasdaq Excessive Reverse Stock Split Rule, if a company’s common shares fail to meet the minimum bid price requirement and the company has effected a reverse stock split within the prior one-year period, it will not be eligible for any compliance period to address a bid price deficiency. Accordingly, if our common shares fall out of compliance with the minimum bid requirement within a one-year period following our August 25, 2025 share consolidation, we will be issued a delisting determination rather than being granted a compliance period. Under these circumstances, we could appeal the delisting determination to a Hearings Panel, during which time any suspension or delisting action will be stayed. This amendment builds upon a 2020 rule change, which established an automatic delisting threshold for companies that have conducted one or more reverse stock splits within a two-year period with a cumulative ratio of 250 shares or more to one. Companies that meet this threshold are also ineligible for a compliance period and are subject to delisting (subject to a stay pursuant to the appeal processes).

If Nasdaq determines to delist our securities from trading on its exchange and we are unable to obtain listing on another national securities exchange, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our shareholders:

● the liquidity of our common shares;

● the market price of our common shares;

● our ability to obtain financing for the continuation of our operations;

● the number of investors that will consider investing in our common shares;

● the number of market makers in our common shares;

● the availability of information concerning the trading prices and volume of our common shares; and

● the number of broker-dealers willing to execute trades in our common shares.

Investors in this Offering will experience immediate and substantial dilution in the book value of their investment.

The public offering price will be substantially higher than the net tangible book value per share of our outstanding common shares. As a result, investors in this Offering will incur immediate dilution of $2.13 per share based on the assumed public offering price of $8.95 per Common Unit in this Offering. Investors in this Offering will pay a price per common share that substantially exceeds the book value of our assets after subtracting our liabilities. See “Dilution” for a more complete description of how the value of your investment will be diluted upon the completion of this Offering. The description in this paragraph assumes no sale of Pre-funded Units, which, if sold, would reduce the number of common shares that we are offering on a one-for-one basis.

Our management will have broad discretion over the use of the proceeds we receive in this Offering and might not apply the proceeds in ways that increase the value of your investment.

Our management will have broad discretion over the use of our net proceeds from this Offering, and you will be relying on the judgment of our management regarding the application of these proceeds. Our management might not apply our net proceeds in ways that ultimately increase the value of your investment. We expect to use the net proceeds from this Offering to fund working capital requirements, general corporate purposes and the advancement of business objectives. Our management might not be able to yield a significant return, if any, on any investment of these net proceeds. You will not have the opportunity to influence our decisions on how to use our net proceeds from this Offering.

We may seek to raise additional funds or develop strategic relationships by issuing securities that would dilute your ownership. Depending on the terms available to us, if these activities result in significant dilution, it may negatively impact the trading price of our common shares.

Any additional financing that we secure may require the granting of rights, preferences or privileges senior to, or pari passu with, those of our common shares. Any issuances by us of equity securities may be at or below the prevailing market price of our common shares and in any event may have a dilutive impact on your ownership interest, which could cause the market price of our common shares to decline. We may also raise additional funds through the incurrence of debt or the issuance or sale of other securities or instruments senior to our common shares, which may be highly dilutive. The holders of any securities or instruments we may issue may have rights superior to the rights of our common shareholders. If we experience dilution from the issuance of additional securities and we grant superior rights to new securities over holders of our common shares, it may negatively impact the trading price of our common shares and you may lose all or part of your investment.

There is no public market for the Pre-funded Warrants being offered in this Offering.

There is no established public trading market for the Pre-funded Warrants, and we do not expect a market to develop. In addition, we do not intend to apply to list the Pre-funded Warrants on any national securities exchange or other nationally recognized trading system. Without an active market, the liquidity of the Pre-funded Warrants will be limited.

Holders of the Pre-funded Warrants and Warrants will have no rights as a common shareholder until they acquire our common shares, except as otherwise set forth therein.

Until holders of the Pre-funded Warrants and Warrants acquire our common shares upon exercise of the Pre-funded Warrants and Warrants, the holders will have no rights with respect to our common shares issuable upon exercise of the Pre-funded Warrants or Warrants, except as otherwise set forth in the Pre-funded Warrants or Warrants. Upon exercise of the Pre-funded Warrants or Warrants, the holder will be entitled to exercise the rights of a common shareholder as to the security exercised only as to matters for which the record date occurs after the exercise.

The Warrants are speculative in nature.

Commencing on the date of issuance, holders of the Warrants may exercise their right to acquire the common shares and pay the stated exercise price per share until exercised in full. There can be no assurance that the market price of our common shares will ever equal or exceed the exercise price of the Warrants offered by this prospectus, and if so, the Warrants would expire without value.

8

A possible “short squeeze” due to a sudden increase in demand of our common shares that largely exceeds supply may lead to price volatility in our common shares.

Following this Offering, investors may short sell our common shares to hedge existing exposure in our common shares or to speculate on the price of our common shares. Speculation on the price of our common shares may involve long and short exposures. Short selling involves selling securities that are not owned at the time of sale with the expectation that the market price will decline, enabling the investor to repurchase those securities at a lower price. To the extent aggregate short exposure exceeds the number of our common shares available for purchase in the open market, investors with short exposure may have to pay a premium to repurchase our common shares for delivery to lenders of our common shares. Those repurchases may in turn, dramatically increase the price of our common shares until investors with short exposure are able to purchase additional common shares to cover their short position. This is often referred to as a “short squeeze.” A short squeeze could lead to volatile price movements in our common shares that are not directly correlated to the performance or prospects of our company and once investors purchase the common shares necessary to cover their short position the price of our common shares may decline. This dynamic may occur regardless of our actual financial condition, results of operations or prospects. A short squeeze, or the perception that it could occur, may lead to extreme and temporary increases in the price of our common shares that are not sustainable and are unrelated to our underlying business fundamentals. Once the buying activity associated with covering short positions subsides, our share price may experience a rapid decline, resulting in significant losses to investors who purchase our shares at inflated levels.

This Offering may cause the trading price of our common shares to decrease.

The number of Warrants, common shares and/or Pre-funded Warrants and the underlying common shares we propose to issue and ultimately will issue if this Offering is completed, may result in an immediate decrease in the trading price of our common shares. This decrease could occur immediately upon announcement or completion of this Offering and may continue for an extended period thereafter. We cannot predict the effect, if any, that the availability of shares for future sale represented by the Warrants and Pre-funded Warrants issued in connection with the Offering will have on the trading price of our common shares from time to time. The holders of Pre-funded Warrants and Warrants may choose to exercise their warrants and sell the underlying common shares at times when it is advantageous to them, which could further increase the number of common shares available for sale in the public market and exacerbate price declines. Because the timing and volume of sales of our common shares following the exercise of the Pre-funded Warrants and Warrants are uncertain, the market price of our common shares may be volatile and subject to fluctuations unrelated to our operating performance or prospects.

In making your investment decision, you should understand that we and the placement agent have not authorized any other party to provide you with information concerning us or this Offering.

You should carefully evaluate all of the information in this prospectus before investing in our company. We may receive media coverage regarding our company, including coverage that is not directly attributable to statements made by our officers, that incorrectly reports on statements made by our officers or employees, or that is misleading as a result of omitting information provided by us, our officers or employees. We and the placement agent have not authorized any other party to provide you with information concerning us or this Offering, and you should not rely on unauthorized information in making an investment decision.

Risks Related to Our Business

Regulations are constantly changing, and in the future our business may be subject to additional regulations that increase our compliance costs.

We believe we understand the current laws and regulations to which our products and product candidates are and will be subject. However, federal, state and foreign laws and regulations relating to the sale of our products are subject to future changes, as are administrative interpretations of laws and regulations. If we fail to comply with such federal, state or foreign laws or regulations, we may fail to obtain regulatory approval for our products and, if we have already obtained regulatory approval, we could be subject to enforcement actions, including injunctions preventing us from conducting our business, withdrawal of clearances or approvals and civil and criminal penalties. In the event that federal, state, and foreign laws and regulations change, we may incur additional costs to seek government approvals, in addition to the clearance from the FDA in order to sell or market our products. If we are slow or unable to adapt to changes in existing regulatory requirements or the promulgation of new regulatory requirements or policies, we or our licensees may, following approval, lose marketing approval for our products which will impact our ability to conduct business in the future.

The FDA’s upcoming actions regarding regulations, guidance, and enforcement are particularly unpredictable, as a result of the recent change of presidential administration, which is expected to bring significant changes to policy initiatives.

We may be unable to adequately protect our intellectual property rights, which could affect our ability to compete.

We own patents, trademarks, copyrights, and other forms of intellectual property related to our business, and we license intellectual property rights from third parties. The U.S. Government generally receives non-exclusive licenses to certain intellectual property we develop. As a result, our intellectual property on which we depend and our access to and use of certain supplier intellectual property could be negatively affected.

Our intellectual property is also subject to challenge, invalidation, misappropriation, or circumvention by third parties. In the event of infringement of our intellectual property rights, breach of a confidentiality agreement, or unauthorized disclosure of proprietary information, we may not have adequate legal remedies to protect our intellectual property. Litigation to determine the scope of our rights, even if successful, could be costly and a diversion of management’s attention. In addition, trade secrets may otherwise become known or be independently developed by competitors. If we are unable adequately to protect our intellectual property rights, our business could be adversely affected.

This prospectus, and the documents incorporated by reference herein may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical facts contained in this prospectus, including statements regarding our future results of operations and financial position, business strategy and plans and our objectives for future operations, are forward-looking statements. The words “believe,” “expect,” “may,” “will,” “should,” “could,” “would,” “seek,” “intend,” “plan,” “goal,” “project,” “estimate,” “anticipate” “strategy,” “future,” “likely,” and similar expressions are intended to identify forward-looking statements.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this prospectus. We have based these forward-looking statements largely on our current expectations about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in “Risk Factors.” Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this prospectus may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this prospectus to conform these statements to actual results or to changes in our expectations. Our forward-looking statements do not reflect the potential impact of any future acquisitions, merger, dispositions, joint ventures, spinouts or investments we may undertake. We qualify all of our forward-looking statements by these cautionary statements.

USE OF PROCEEDS

We estimate that the net proceeds we will receive from the sale of our securities in this Offering, assuming all the securities we are offering are sold, after deducting placement agent fees and other estimated offering expenses payable by us, and assuming no sale of any Pre-funded Units and no exercise of the Warrants being issued in this Offering, will be approximately $22.71 million, based on an assumed public offering price of $8.95 per Common Unit.

However, because this is a best-efforts offering and there is no minimum offering amount required as a condition to the closing of this Offering, the actual offering amount, the placement agent fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus.

We currently expect to use the net proceeds from this Offering to fund working capital requirements, general corporate purposes and the advancement of business objectives. The amounts and timing of these expenditures will depend on numerous factors, including the development of our current business initiatives. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds from this Offering and our management will have discretion and flexibility in applying the net proceeds of this Offering. An investor will not have the opportunity to evaluate the economic, financial or other information on which we base our decisions on how to use the proceeds. We may use the proceeds of this Offering for purposes with which you do not agree. Moreover, our management may use the net proceeds for corporate purposes that may not result in our being profitable or increase our market value.

A $0.10 increase (decrease) in the assumed public offering price of $8.95 per Common Unit would increase (decrease) the net proceeds to us from this Offering by approximately $0.26 million, assuming the number of Common Units offered by us, as set forth on the cover of this prospectus, remains the same and assuming no sale of Pre-funded Units and, after deducting placement agent fees and estimated expenses payable by us. An increase (decrease) of 50,000 or 500,000 in the number of Common Units offered by us in this Offering, would increase (decrease) the net proceeds to us from this Offering by approximately $0.41 million or $4.14 million, respectively, assuming the public offering price of $8.95 per Common Unit, remains the same and assuming no sale of Pre-funded Units and, after deducting placement agent fees and estimated expenses payable by us. The information above is illustrative only and will change based on the actual public offering price and other terms of this Offering determined at pricing.

11

CAPITALIZATION

The following table sets forth our capitalization as of October 31, 2025 as follows:

● on an actual basis; and

● on an as adjusted, basis to reflect the issuance and sale by us of 2,793,296 Common Units in this Offering at the assumed public offering price of $8.95 per Common Unit (which is the last reported sale price of our common shares on Nasdaq on December 19, 2025) and assuming no sale of Pre-funded Units, after deducting placement agent fees and estimated offering expenses payable by us.

The information below is illustrative only. Our capitalization following the closing of this Offering will change based on the actual public offering price and other terms of this Offering determined at pricing. You should read this table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related notes included in the 2025 Form 10-K and Quarterly Report on Form 10-Q for the period ended October 31, 2025.

The table above is based on 1,883,906 common shares outstanding as of October 31, 2025; assumes no sale of Pre-funded Units and also excludes, as of October 31, 2025, the following:

● 1,681,986 common shares issuable upon the exercise of outstanding warrants, at a weighted average exercise price of $58.86;

● 50,951 common shares issuable upon the exercise of outstanding options, at a weighted average exercise price of $242.15;

● 40,000 common shares issuable upon the conversion of outstanding restricted share units, at a weighted average exercise price of $0.01; and

● 165,935 common shares issuable upon the conversion of outstanding performance share units, at a weighted average exercise price of $0.01.

12

DILUTION

If you invest in our Common Units in this Offering, your investment will be immediately and substantially diluted to the extent of the difference between the public offering price per Common Unit (assuming no value is attributed to the Warrants and no Pre-funded Warrants are sold in the Offering) and the pro forma net tangible book value per Common Unit after giving effect to the Offering (assuming no value is attributed to the Warrants and no Pre-funded Warrants are sold in the Offering).

Our net tangible book value as of October 31, 2025 was approximately $9.2 million or $4.87 per share. Net tangible book value per share represents our total tangible assets less total liabilities, divided by the number of common shares outstanding.

Our as adjusted net tangible book value dilution per Common Unit to new investors represents the difference between the amount per Common Unit in the Offering and the as adjusted net tangible book value per Common Unit immediately after completion of the Offering. After giving effect to the Offering and our sale of the Common Units in the Offering at an assumed public offering price of $8.95 per Common Unit (and assuming no sale of Pre-funded Units), and after deducting the placement agent fees and estimated offering expenses payable by us, our as adjusted net tangible book value as of October 31, 2025, would have been $31.8 million, or $6.82 per common share. This represents an immediate increase in as adjusted net tangible book value of $1.95 per common share to existing shareholders and an immediate dilution in net tangible book value of $2.13 per share of common share to purchasers of Common Units in this Offering, as illustrated in the following table, based on shares outstanding as of October 31, 2025.

Assumed offering price per share	$	8.95
Actual Net tangible book value per share before this Offering(1)	$	4.87
Increase in net tangible book value per share attributable to new investors(2)	$	1.95
As adjusted net tangible book value per share after this Offering(3)	$	6.82
Immediate dilution in as adjusted net tangible book value per share to new investors	$	2.13

(1)	Determined by dividing (i) net tangible book value (total assets less intangible assets) less total liabilities by (ii) the total number of common shares 1,883,906 issued and outstanding prior to the Offering.
(2)	Represents the difference between (i) as adjusted, net tangible book value per share after this Offering and (ii) net tangible book value per share as of October 31, 2025.
(3)	Determined by dividing (i) as adjusted, net tangible book value, which is our as adjusted net tangible book value plus the cash proceeds of this Offering, after deducting the estimated offering expenses payable by us, by (ii) the total number of common shares to be outstanding following this Offering.

13

Each $0.50 increase (decrease) in the assumed public offering price of $8.95 per Common Unit would increase (decrease) the as adjusted net tangible book value per share after this Offering by $0.28 per share and the dilution to new investors purchasing Common Units in this Offering by $0.46 per share, assuming the number of Common Units offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated placement agent fees.

The information discussed above is illustrative only and will adjust based on the actual public offering price, the actual number of Common Units that we offer in this Offering, and other terms of this Offering determined at the time of pricing. The foregoing discussion and table assume no issuance of Pre-funded Units, which if sold, would reduce the number of common shares that we are offering on a one-for-one basis. In addition, we may choose to raise additional capital due to market conditions or strategic considerations. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

The number of common shares outstanding set forth in the table above excludes, as of October 31, 2025:

● 1,681,986 common shares issuable upon the exercise of outstanding warrants, at a weighted average exercise price of $58.86;

● 50,951 common shares issuable upon the exercise of outstanding options, at a weighted average exercise price of $242.15;

● 40,000 common shares issuable upon the conversion of outstanding restricted share units, at a weighted average exercise price of $0.01; and

● 165,935 common shares issuable upon the conversion of outstanding performance share units, at a weighted average exercise price of $0.01.

15

Duration and Exercise Price

Each Warrant offered hereby will have an initial exercise price per share equal to $11.1875, equal to 125% of the assumed public offering price of one Common Unit of $8.95 per Common Unit (which is the last reported sales price of our common shares on the Nasdaq on December 19, 2025.

The exercise price and number of common shares issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, share splits, reorganizations or similar events affecting our common shares and the exercise price.

Exercisability

Each Warrant may be exercised, in cash at the election of the holder at any time following the date of issuance until five years from the date of issuance. The Warrants will be exercisable in whole or in part by delivering to us a completed instruction form for exercise and complying with the requirements for exercise set forth in the Warrant. Payment of the exercise price may be made in cash, in which case the holder would receive upon such exercise the net number of common shares determined according to the formula set forth in the Warrant.

If at any time there is no effective registration statement available for the issuance of the shares underlying the Warrants, the holder may elect to exercise the Warrants on cashless basis, in which case the holder would receive upon such exercise the net number of common shares determined according to the formula set forth in the Warrants.

Exercise Limitation

In general, a holder will not have the right to exercise any portion of a Warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% or 9.99%, at the election of the holder, of the number of common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrant. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99% upon notice to us, provided, that any increase in this limitation will not be effective until 61 days after such notice from the holder to us and such increase or decrease will apply only to the holder providing such notice.

Transferability

Subject to applicable laws, a Warrant may be transferred at the option of the holder upon surrender of the Warrant to us together with the appropriate instruments of transfer.

Fractional Shares

No fractional common shares will be issued upon the exercise of the Warrants. Rather, the number of common shares to be issued will, at our election, either be rounded up to the nearest whole number or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Trading Market

We have applied to have the Warrants offered in this offering listed on Nasdaq under the symbol “BCTXX”. No assurance can be given that such listing will be approved or that a trading market will develop.

Right as a Shareholder

Except as otherwise provided in the Warrants or by virtue of such holder’s ownership of common shares, the holders of the Warrants do not have the rights or privileges of holders of our common shares, including any voting rights, until they exercise their Warrants.

Warrant Agent

The Warrants will be issued in registered form under a warrant agency agreement between Computershare Inc. and Computershare Trust Company, N.A., as warrant agent, and us.

Additionally, as more fully described in the Warrants, in the event of certain fundamental transactions, the holders of the Warrants will be entitled to receive consideration in an amount equal to the Black Scholes Value (as defined in the Warrant) of the remaining unexercised portion of the Warrants on the date of consummation of such fundamental transaction.

Pre-funded Warrants to be Issued in this Offering

The following summary of certain terms and provisions of the Pre-funded Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Pre-funded Warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-funded Warrant for a complete description of the terms and conditions of the Pre-funded Warrants.

Each Pre-funded Warrant offered hereby will have an initial exercise price per share equal to $0.001. The Pre-funded Warrants will be immediately exercisable and will expire when exercised in full. The exercise price and number of common shares issuable upon exercise is subject to appropriate adjustment in the event of share dividends, share splits, reorganizations or similar events affecting our common shares and the exercise price.

16

Exercisability

The Pre-funded Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of common shares purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Pre-funded Warrant to the extent that the holder would own more than 4.99%/9.99% of the outstanding common shares immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding shares after exercising the holder’s Pre-funded Warrants up to 9.99% of the number of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-funded Warrants. Purchasers of Pre-funded Warrants in this Offering may also elect prior to the issuance of the Pre-funded Warrants to have the initial exercise limitation set at 9.99% of our outstanding common shares.

Cashless Exercise

In lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of common shares determined according to a formula set forth in the Pre-funded Warrants.

No fractional common shares will be issued upon the exercise of the Pre-funded Warrants. Rather, the number of common shares to be issued will, at our election, either be rounded up to the next whole share or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Subject to applicable laws, a Pre-funded Warrant may be transferred at the option of the holder upon surrender of the Pre-funded Warrant to us together with the appropriate instruments of transfer and funds sufficient to pay any transfer taxes payable upon such transfer.

Trading Market

There is no public trading market available for the Pre-funded Warrants on any securities exchange or nationally recognized trading system, and we do not expect a public trading market to develop. We do not intend to list the Pre-funded Warrants on any securities exchange or nationally recognized trading market. Without a trading market, the liquidity of the Pre-funded Warrants will be extremely limited.

Right as a Shareholder

Except as otherwise provided in the Pre-funded Warrants or by virtue of such holder’s ownership of common shares, the holders of the Pre-funded Warrants do not have the rights or privileges of holders of our common shares, including any voting rights, until they exercise their Pre-funded Warrants. The Pre-funded Warrants will provide that holders have the right to participate in distributions or dividends paid on common shares.

Fundamental Transaction

In the event of a fundamental transaction, as described in the Pre-funded Warrants and generally including (i) our merger or consolidation with or into another person, (ii) the sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of our assets, (iii) any purchase offer, tender offer or exchange offer pursuant to which holders of our common shares are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of our outstanding common shares or 50% or more of the voting power of our common equity, (iv) any reclassification, reorganization or recapitalization of our common shares or any compulsory share exchange or (v) any share purchase agreement or other business combination with another person or group of persons whereby such other person or group acquires 50% or more of our outstanding common shares or 50% or more of the voting power of our common equity, the holders of the Pre-funded Warrants will be entitled to receive upon exercise of the Pre-funded Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Pre-funded Warrants immediately prior to such fundamental transaction on a net exercise basis.

Description of Placement Agent Warrants

We have agreed to issue to the placement agent warrants to purchase such number of common shares equal to 5% of the aggregate number of Common Units and Pre-funded Units sold in this Offering.

Certain Important Provisions of our Articles and the BCBCA

The following is a summary of certain important provisions of our Articles and certain related sections of the Business Corporations Act (British Columbia) (“BCBCA”). Please note that this is only a summary and is not intended to be exhaustive. This summary is subject to, and is qualified in its entirety by reference to, the provisions of our Articles and the BCBCA.

Directors

Power to vote on matters in which a director has a disclosable interest. Under the BCBCA, a director who has a material interest in a contract or transaction or who is a director or senior officer of, or has a material interest in, a person who has a material interest in the contract or transaction, whether entered into or proposed to be entered into, if that contract or transaction is material to us, must disclose such interest to us. A director does not hold a disclosable interest in a contract or transaction if the contract or transaction: (i) is an arrangement by way of security granted by us for money loaned to, or obligations undertaken by, the director, or a person in whom the director has a material interest, for our benefit or for one of our affiliates’ benefit; (ii) relates to an indemnity or insurance permitted under the BCBCA; (iii) relates to the remuneration of the director in his or her capacity as director, officer, employee or agent of our company or of one of our affiliates; (iv) relates to a loan to our company while the director, or a person in whom the director has a material interest, is or is to be the guarantor of some or all of the loan; or (v) has been or will be made with or for the benefit of a corporation that is affiliated with us and the director is also a director or senior officer of that corporation or an affiliate of that corporation.

A director who holds a disclosable interest in a contract or transaction in which we have entered or propose to enter is not entitled to vote on any directors’ resolution to approve that contract or transaction, unless all the directors have a disclosable interest in that contract or transaction, in which case any or all of those directors may vote on such resolution. A director who holds a disclosable interest in a contract or transaction in which we have entered or propose to enter and who is present at the meeting of directors at which the contract or transaction is considered for approval may be counted in the quorum at the meeting whether or not the director votes on any or all of the resolutions considered at the meeting.

A director or senior officer who holds any office or possesses any property, right or interest that could result, directly or indirectly, in the creation of a duty or interest that materially conflicts with that individual’s duty or interest to us as a director or senior officer, must disclose the nature and extent of the conflict as required by the BCBCA.

Directors are also required to comply with certain other relevant provisions of the BCBCA regarding conflicts of interest.

Directors’ power to determine the remuneration of directors. The remuneration of our directors is determined by our directors subject to our Articles. If the directors so decide, the remuneration of the directors, if any, will be determined by the shareholders. The remuneration may be in addition to any salary or other remuneration paid to any of our employees (including executive officers) who are also directors.

Number of shares required for director’s qualification. Directors do not need to own shares of the Company to qualify to be a director.

Shareholder Meetings

Subject to applicable exchange requirements, we must hold a general meeting of our shareholders at least once every calendar year and not more than 15 months after the date of the annual general meeting for the preceding calendar year. A meeting of our shareholders may be held anywhere in or outside British Columbia at a time and place determined by our board of directors. The board may also determine that a meeting of shareholders may be held entirely by means of telephone, electronic or other communications facilities that permit all participants to communicate with each other during the meeting.

A notice to convene a meeting, specifying the date, time and location of the meeting, and, where a meeting is to consider special business, the general nature of the special business must be sent to each shareholder entitled to attend the meeting and to each director not less than 21 days and no more than two months prior to the meeting, although, as a result of applicable securities laws, the minimum time for notice is effectively longer in most circumstances. Under the BCBCA, shareholders entitled to notice of a meeting may waive or reduce the period of notice for that meeting, provided applicable securities laws are met. The accidental omission to send notice of any meeting of shareholders to, or the non-receipt of any notice by, any person entitled to notice does not invalidate any proceedings at that meeting.

Our Articles provide that a quorum for the transaction of business at a meeting of our shareholders is met where there are two persons who are, or who represent by proxy, shareholders who, in the aggregate, hold at least 33.33% of the issued shares entitled to vote.

If a quorum is not present within one-half hour from the time set for such meeting, the meeting stands adjourned to the same day in the next week at the same time and place, unless the meeting is requisitioned by shareholders, in which case the meeting is dissolved. At such adjourned meeting, if within one-half hour of the time set for such meeting, the person or persons present and being, or representing by proxy, one or more shareholder entitled to vote at the meeting, constitute quorum and any business may be transacted which might have been transacted at the meeting as originally notified.

18

When a quorum is present or represented at any meeting, on matters requiring approval by an ordinary resolution, the vote of the holders of at least a majority of the common shares present in person or represented by proxy shall be sufficient to approve such matter, including the election of directors, and on matters requiring approval by a special resolution, the vote of holders holding at least 662/3% of the common shares present in person or represented by proxy shall be sufficient to approve such matter.

Each shareholder of record of the Company shall be entitled at each meeting of shareholders to one vote for each common share held. Upon the demand of any shareholder, the vote for directors and the vote upon any question before the meeting shall be conducted by poll.

At any meeting of the shareholders, any shareholder may be represented and vote by a proxy or proxies appointed by an instrument in writing. No proxy shall be used to vote at a meeting of the shareholders unless it shall have been validly deposited with the Company in accordance with the Articles, the BCBCA and applicable securities laws. All questions regarding the qualification of voters, the validity of proxies and the acceptance or rejection of votes shall be decided by the chair of the meeting who shall be appointed in accordance with the Articles and the BCBCA.

Any action which may be taken by the vote of the shareholders at a meeting, may be taken without a meeting if authorized by the written consent of shareholders holding, on matters requiring approval by an ordinary resolution, at least 66 2/3% of the common shares having the right to vote on such matter and on matters requiring approval by a special resolution, all of the common shares having the right to vote on such matter.

Our directors, our secretary (if any), our auditor and any other persons invited by our chair or directors or with the consent of those at the meeting are entitled to attend any meeting of our shareholders but will not be counted in the quorum or be entitled to vote at the meeting unless they are a shareholder or proxy holder entitled to vote at the meeting.

Shareholder Proposals

Under the BCBCA, qualified shareholders, together with the submitter, holding (a) at least one percent (1%) of our issued common shares or (b) common shares having a fair market value in excess of C$2,000, may make proposals for matters to be considered at the annual general meeting of shareholders. Such proposals must be sent to us in advance of any proposed meeting by delivering a timely written notice in proper form to our registered office in accordance with the requirements of the BCBCA and be accompanied by one written statement in support of the proposal. The notice must include information on the business the shareholder intends to bring before the meeting.

Forum Selection

We have not included a forum selection provision in our Articles.

Ownership Limitation and Transfer of Shares

Our common shares are not subject to transfer restrictions under our Articles, but may be subject to restrictions on transfer or prohibited by another instrument, applicable law or the rules of a stock exchange on which the shares are listed for trade. The ownership or voting of our common shares by non-residents of Canada is not restricted by our Articles.

Share Transfers

Pursuant to our Articles, a transfer of a share must not be registered unless:

(a)	except as exempted by the BCBCA, a duly signed proper instrument of transfer in respect of the share has been received by the Company;
(b)	if a share certificate has been issued by the Company in respect of the share to be transferred, that share certificate has been surrendered to the Company; and
(c)	if a non-transferable written acknowledgment of the shareholder’s right to obtain a share certificate has been issued by the Company in respect of the share to be transferred, that acknowledgment has been surrendered to the Company.

19

Change in Control

Our Articles do not contain restrictions on change in control.

Election of Directors

Our common shares do not have cumulative voting rights for the election of directors. As a result, the holders of a majority of the common shares represented in person or by proxy at a shareholders meeting have the power to elect all of our directors.

The directors shall be elected at the annual meeting of the shareholders by ordinary resolution, being a simple majority vote of holders of our common shares, participating and voting at such meeting, and each director elected shall hold office until the next annual general meeting held for the purpose of the election of directors is considered or his or her successor is duly elected or appointed, unless he or she resigns, is removed or becomes disqualified in accordance with the Articles and BCBCA. However, in the event of any casual vacancy in our board of directors such vacancy may be filled by the remaining directors and each director so elected shall hold office until his successor is elected at an annual or a special meeting of the shareholders held for such purpose. Shareholders may by special resolution, being the approval of two-thirds of the outstanding common shares participating and voting at such meeting, at any time peremptorily terminate the term of office of all or any of the directors by vote at a meeting called for such purpose and elect, or appoint by ordinary resolution, a director to fill the resulting vacancy. Such removal shall be effective immediately, even if successors are not elected simultaneously and the vacancies on the board of directors resulting therefrom shall be filled by the directors or by the shareholders by ordinary resolution.

The shareholders may elect a director or directors at any time to fill any vacancy or vacancies not filled by the directors. If the board of directors accepts the resignation of a director tendered to take effect at a future time, the board or the shareholders shall have power to elect a successor to take office when the resignation is to become effective.

Pursuant to the requirements of the TSX, the board has adopted a policy for majority voting for individual directors (the “Majority Voting Policy”). The proxy card for the meetings of shareholders enables each shareholder to vote for, or withhold their common shares from voting on, the election of each nominee separately. In accordance with the terms of the Majority Voting Policy, if the votes “for” the election of a nominee are fewer than the votes “withheld”, the nominee will be required to tender his or her resignation promptly after the meeting for the consideration of the Nominating and Corporate Governance Committee of the Board (the “Governance Committee”). Absent exceptional circumstances that would warrant the continued service of the applicable director on the board, the Governance Committee is expected to recommend acceptance of the resignation by the board. The Governance Committee will make a recommendation to the board after reviewing the matter, and the board will then decide whether to accept or reject the resignation. Following the board’s decision, which must be made within 90 days after the date of the meeting, the board will promptly issue a news release publicly disclosing its decision whether to accept or reject the applicable director’s resignation, including the reasons for rejecting the resignation, if applicable. If a resignation is accepted, subject to any corporate law restrictions, the board may leave the vacancy unfilled or appoint a new director to fill the vacancy. The director whose resignation is being considered will not participate in any Governance Committee or board deliberations as to whether to accept or reject the resignation. The Majority Voting Policy does not apply in circumstances involving contested director elections (i.e., where the number of nominees exceeds the number of directors to be elected).

Our board adopted an Advance Notice Policy on December 18, 2015 (the “Advance Notice Policy”), under which nominating shareholders must give written notice of their intention to do so to our Corporate Secretary. Any such notice also must include the information required by the Advance Notice Policy. Subject to compliance with the Advance Notice Policy, written notice of director nominees must be made to the Corporate Secretary of the Company not less than 30 nor more than 65 days prior to the date of the shareholders meeting, provided, however, that in the event that the meeting is to be held on a date that is less than 50 days after the date (the “Notice Date”) on which the first public announcement (as defined below) of the date of the meeting was made, notice by the nominating shareholder may be made not later than the close of business on the 10th day following such Notice Date. Any adjournment or postponement of a meeting of shareholders or announcement thereof does not commence a new time period for the giving of a nominating shareholder’s notice.

20

No reduction of the authorized number of directors shall have the effect of removing any director prior to the expiration of his term of office.

Anti-Takeover Measures

Our Articles do not provide for any anti-takeover measures.

Changes in Capital

Our Articles enable us to increase or reduce our share capital. Any such changes are subject to the provisions of the BCBCA.

(a)	the import or export of capital, including the availability of cash and cash equivalents for use by the Company’s group; and
(b)	the remittance of dividends, interest or other payments to nonresident holders of the Company’s securities.

Item 14. Indemnification of Directors and Officers.

Under the BCBCA, subject to certain limitations set forth in section 163 of the BCBCA, a company may (a) indemnify: an eligible party against all eligible penalties to which the eligible party is or may be liable, and (b) after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by an eligible party in respect of that proceeding.

For the purposes of this section:

“eligible party” means (i) a current or former director or officer of that company; (ii) a current or former director or officer of another corporation if, at the time such individual held such office, the corporation was an affiliate of the company, or if such individual held such office at the company’s request; or (iii) an individual who, at the request of the company, held, or holds, an equivalent position to that of, a director or officer of a partnership, trust, joint venture or other unincorporated entity;

“eligible penalty” means a judgment, penalty or fine awarded or imposed in, or an amount paid in settlement of, an eligible proceeding; and

“eligible proceeding” means a proceeding in which an eligible party or any of the heirs and personal or other legal representatives of the eligible party, by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the company or an associated corporation (A) is or may be joined as a party, or (B) is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding.

A company must not indemnify or pay the expense of an eligible party if: (i) in relation to the subject matter of the eligible proceeding, the eligible party did not act honestly and in good faith with a view to the best interests of such company or the other entity, as the case may be; or (ii) in the case of an eligible proceeding other than a civil proceeding, the eligible party did not have reasonable grounds for believing that the eligible party’s conduct was lawful. A company cannot indemnify an eligible party if it is prohibited from doing so under its Articles, by the BCBCA or by other applicable law.

A company may pay, as they are incurred in advance of the final disposition of an eligible proceeding, the expenses actually and reasonably incurred by an eligible party in respect of that proceeding only if the eligible party has provided the company with an undertaking that, if it is ultimately determined that the payment of expenses was prohibited by the BCBCA, the eligible party will repay any amounts advanced. Subject to the aforementioned prohibitions on indemnification, a company must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by an eligible party in respect of that proceeding if the eligible party has not been reimbursed for such expenses, and was wholly successful, on the merits or otherwise, in the outcome of such proceeding or was substantially successful on the merits in the outcome of such proceeding.

On application from an eligible party, a court may make any order the court considers appropriate in respect of an eligible proceeding, including the indemnification of an eligible party against any liability incurred by the eligible party in respect of an eligible proceeding, the payment of some or all of the expenses incurred by an eligible party in respect of an eligible proceeding and the enforcement of an indemnification agreement. As permitted by the BCBCA, under Section 21 of the Articles, we are required to indemnify our directors and former directors (and such individual’s respective heirs and legal representatives) and we will indemnify any such person to the extent permitted by the BCBCA.

We maintain insurance policies relating to certain liabilities that our directors and officers may incur in such capacity.

Insofar as indemnification for liabilities under the Securities Act may be permitted to officers, directors or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that is it is the opinion of the SEC that such indemnification is against public policy as expressed in such Securities Act and is, therefore, unenforceable.

Item 17. Undertakings.

(1) The undersigned registrant hereby undertakes:

(a) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§ 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” or “Calculation of Registration Fee” table, as applicable, in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(a)(i), (1)(a)(ii), and (1)(a)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(b) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(c) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(d) that, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

II-7

(e) that, for purposes of determining any liability under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(f) insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (e) that, for purposes of determining any liability under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
