The Debentures are unsecured obligations of the Company, mature August 30, 2026 (the "Maturity Date"), and bear interest at a rate of 10% per annum with such interest payable on a quarterly basis in either cash or, at the sole discretion of the Company, in common shares of the Company ("Shares"). The principal outstanding under the Debentures will be convertible into Shares at any time, at the option of the holder, at the closing price of the Shares on the Canadian Securities Exchange (the "CSE") on the day notice of conversion is received by the Company, subject to the pricing requirements in the policies of the CSE. If a holder elects to convert principal into Shares, all accrued and unpaid interest on the amount to be converted will also be satisfied with the issuance of Shares to such holder.

Participants in the Offering also received, for every $1,000 of Debentures, 4,000 transferable common share purchase warrants ("Debenture Warrants") that, for each Debenture Warrant, entitle the holder thereof to acquire one Share at an exercise price of $0.25 per Share until September 15, 2026.

The Company intends to use the net proceeds raised from the Offering for research and development, general corporate purposes, and working capital. No Finder's fees were applicable to the Offering. All securities issued pursuant to the Offering are subject to a statutory hold period expiring four months and one day, expiring January 16, 2026.

Certain insiders of the Company participated in the Offering in the aggregate amount of $50,000 as follows: James Passin, Chief Financial Officer and Director of the Company, purchased Debentures in the amount of $25,000 and Kenneth Kovan, Chief Operating Officer of the Company, purchased Debentures in the amount of $25,000. In this regard, the Offering is considered a related party transaction subject to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company relied on exemptions from the formal valuation and minority shareholder approval requirements provided under sections 5.5(a) and 5.7(1)(a) of MI 61-101 on the basis that participation by insiders of the Company in the Offering will not exceed 25% of the fair market value of the Company's market capitalization, as calculated in accordance with MI 61-101.

The securities described herein have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or any state securities laws, and may not be offered or sold within the United States except in compliance with the registration requirements of the U.S. Securities Act and applicable state securities laws or pursuant to available exemptions therefrom.

All statements, other than statements of historical fact, included herein, without limitation, statements relating to the future operating or financial performance of the Company, are forward-looking statements. Forward-looking statements are frequently, but not always, identified by words such as "expects", "anticipates", "believes", "intends", "estimates", "potential", "possible", and similar expressions, or statements that events, conditions, or results "will", "may", "could", or "should" occur or be achieved. Forward-looking statements in this news release relate to, among other things, the Offering, including the expected use of proceeds from the Offering. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those expressed or implied in such forward-looking statements.

Forward-looking statements reflect the beliefs, opinions and projections on the date the statements are made and are based upon a number of assumptions and estimates, primarily the assumption that BioVaxys will be successful in developing and testing vaccines, that, while considered reasonable by BioVaxys, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies including, primarily but without limitation, the risk that BioVaxys' vaccines will not prove to be effective and/ or will not receive the required regulatory approvals. With regards to BioVaxys' business, there are a number of risks that could affect the development of its biotechnology products, including, without limitation, the need for additional capital to fund clinical trials, its lack of operating history, uncertainty about whether its products will complete the long, complex and expensive clinical trial and regulatory approval process for approval of new drugs necessary for marketing approval, uncertainty about whether its autologous cell vaccine immunotherapy can be developed to produce safe and effective products and, if so, whether its vaccine products will be commercially accepted and profitable, the expenses, delays and uncertainties and complications typically encountered by development stage biopharmaceutical businesses, financial and development obligations under license arrangements in order to protect its rights to its products and technologies, obtaining and protecting new intellectual property rights and avoiding infringement to third parties and their dependence on manufacturing by third parties.

Many factors, both known and unknown, could cause actual results, performance or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward-looking statements and the parties have made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation, the risk that the Company does not use the proceeds from the Offering as currently expected.
