In the event that the Company fails to file the registration statement by the prescribed deadline or such registration statement is not declared effective by the prescribed deadline or the Company fails to maintain the effectiveness of such registration statement, then the Company shall pay to each holder of registrable securities relating to such registration statement an amount in cash equal to two percent (2%) of such investor’s original principal amount stated in such investor’s Convertible Note on July 16, 2025.

On July 16, 2025, all of the Company’s subsidiaries entered into a subsidiary guaranty (the “Subsidiary Guaranty”), pursuant to which the Company’s subsidiaries agreed to guaranty the Company’s obligations under the Securities Purchase Agreement, the Convertible Notes, and other transaction documents.

(i) The Company must, in its sole discretion, select the number of Advance Shares, not to exceed the Maximum Advance Amount (as defined below), it desires to issue and sell to the Investor in each Advance Notice and the time it desires to deliver each written notice to the Investor setting forth the number of Advance Shares that the Company desires to issue and sell to the Investor (the “Advance Notice”).

(ii) There is no mandatory minimum issuance and sale of Advance Shares by the Company to the Investor and there is no non-usage fee for not utilizing the Commitment Amount or any part thereof.

“Maximum Advance Amount” means the Accelerated Purchase Maximum Advance Amount, Regular Purchase Maximum Advance Amount or Extended Purchase Maximum Advance Amount, as applicable, provided, however, the Maximum Advance Amount shall not exceed the limitations set forth in the EPFA:

(i) “Accelerated Purchase Maximum Advance Amount” in respect of each Advance Notice with an Accelerated Purchase Pricing Period (as defined in the EPFA), an amount of Common Shares equal to the lower of (i) four hundred percent (400%) of the median daily trading volume of the Common Shares (the “Daily Traded Amount”) on the principal market on which the Company’s securities are listed (the “Principal Market”) during the five (5) consecutive Trading Days (as defined in the EPFA) immediately preceding an Advance Notice Date (as defined in the EPFA), and (ii) such number of Common Shares equal to $2,500,000 as of the date of each Advance Notice (determined based on the last closing price of the Common Shares on the Principal Market prior to delivery of such Advance Notice), or such other amount of Common Shares as agreed upon by the Company and the Investor in writing, which may be made via e-mail;

(ii) “Regular Purchase Maximum Advance Amount” in respect of each Advance Notice with a Regular Purchase Pricing Period (as defined in the EPFA), an amount of Common Shares equal to the lower of (i) one hundred percent (100%) the median Daily Traded Amount during the five (5) consecutive Trading Days immediately preceding an Advance Notice Date, and (ii) such number of Common Shares equal to $1,000,000 as of the date of each Advance Notice (determined based on the last closing price of the Common Shares on the Principal Market prior to delivery of such Advance Notice); and

(iii) “Extended Purchase Maximum Advance Amount” in respect of each Advance Notice with an Extended Purchase Pricing Period (as defined in the EPFA), an amount of Common Shares equal to the lower of (i) four hundred percent (400%) of the median Daily Traded Amount during the five (5) consecutive Trading Days immediately preceding an Advance Notice Date, and (ii) such number of Common Shares equal to $2,500,000 as of the date of each Advance Notice (determined based on the last closing price of the Common Shares on the Principal Market prior to delivery of such Advance Notice), or such other amount of Common Shares as agreed upon by the Parties in writing, which may be made via e-mail.

The price per Advance Share will be obtained as follows:

(i) For an Advance Notice selecting an Accelerated Purchase Pricing Period or Extended Purchase Pricing Period, the applicable Market Price multiplied by ninety five percent (95%); and

(ii) For an Advance Notice selecting a Regular Purchase Pricing Period, the applicable Regular Purchase Market Price (as defined in the EPFA) multiplied by ninety three percent (93%).

Pursuant to the terms of the EPFA, if required by the applicable rules of the Principal Market, the Company is required to hold a special meeting of shareholders (the “Shareholder Meeting”), no later than sixty (60) calendar days following the date such approval is required by the applicable rules of the Principal Market, to seek approval of the issuance of Advance Shares under the EPFA equal to and in excess of 20% of the total outstanding Common Shares (such approval, the “Shareholder Approval”). Until Shareholder Approval is obtained, the total cumulative number of Common Shares that may be issued to the Investor will be limited to 19.99% of the number of Common Shares issued and outstanding as of July 13, 2025 (the “Exchange Cap”) pursuant to the requirements of the Nasdaq Stock Market LLC or other applicable rules of the Principal Market. The Exchange Cap will be calculated based on the number of Common Shares issued and outstanding as of July 13, 2025, which number shall be reduced, on a share-for-share basis, by the number of Common Shares issued or issuable pursuant to any transaction or series of transactions that may be aggregated with the transactions contemplated by such agreement under the applicable rules of the Principal Market.

The EPFA contains customary representations, warranties, agreements and conditions, indemnification rights and obligations of the parties. Among other things, the Investor represented to the Company, that it is an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Securities Act).

The offers and sales of the Shares issuable under the EPFA will be made in a private placement in reliance on an exemption from the registration requirements of the Securities Act, pursuant to Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder, and applicable state securities laws. The Company plans to file with the SEC a registration statement relating to the resale of the Advance Shares issuable under the EPFA. The Company cannot draw on the EPFA, and the Advance Shares may not be sold nor may offers to buy be accepted, prior to the time that the registration statement covering the resale of the Advance Shares is declared effective by the SEC.

The foregoing summary of the EPFA does not purport to be complete and is qualified in its entirety by reference to the EPFA, the form of which is filed with this Form 6-K as Exhibit 10.7 and is incorporated herein by reference.
