The Company may cause Yorkville to purchase additional Common Shares under the SEPA from time to time, subject to the satisfaction or waiver of the conditions and limitations set forth in the SEPA. The Company has used part of the net proceeds from the SEPA Advances to prepay a portion of the debenture the Company has outstanding with Yorkville, as described in that certain Current Report on Form 8-K dated September 18, 2025. The Common Shares were issued and sold to Yorkville in reliance upon the exemption from the registration requirements of the Securities Act, afforded by Section 4(a)(2) of the Securities Act. The Company is relying on this exemption from registration based in part on representations made by Yorkville in the SEPA. Yorkville may resell the Common Shares it has purchased from the Company under the SEPA from time to time pursuant to an effective registration statement which has been filed by the Company in accordance with its requirements under the SEPA for such purposes
This report shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.

Forward Looking Statements
This Current Report on Form 8-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995, as amended. Such forward-looking statements include, but are not limited to, statements concerning future sales of Common Shares under the SEPA. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements. In addition, forward-looking statements are typically identified by words such as "plan," "believe," "goal," "target," "aim," "expect," "anticipate," "intend," "outlook," "estimate," "forecast," "project," "continue," "could," "may," "might," "possible," "potential," "predict," "should," "would" and other similar words and expressions, although the absence of these words or expressions does not mean that a statement is not forward-looking. Forward-looking statements are based on the current expectations and beliefs of the Company's management and are inherently subject to a number of factors, risks, uncertainties and assumptions and their potential effects. There can be no assurance that future developments will be those that have been anticipated. Actual results may vary materially from those expressed or implied by forward-looking statements based on a number of factors, risks, uncertainties and assumptions, including the risks and uncertainties detailed from time to time in the Company's filings with the SEC. Potential investors, shareholders and other readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they were made. The Company does not assume any obligation to publicly update any forward-looking statement after it was made, whether as a result of new information, future events or otherwise, except as required by law or regulation. Investors are referred to the full discussion of risks and uncertainties associated with forward-looking statements and the discussion of risk factors contained in the Company's filings with the SEC, which are available at www.sec.gov.
