Amendment to Secured Convertible Debenture Purchase Agreement and First Closing

As previously disclosed in the Current Report on Form 8-K filed by Streamex Corp. (f./k/a BioSig Technologies, Inc.), a Delaware corporation (the “Company”) with the Securities and Exchange Commission on July 9, 2025, August 13, 2025, and October 28, 2025 (combined together the “Prior Form 8-Ks”), the Company entered into a certain Secured Convertible Debenture Purchase Agreement with YA II PN, LTD., a Cayman Islands exempt limited company (“Yorkville” or the “Investor”), for the issuance and sale by the Company of convertible debentures (the “Convertible Debentures,” each, a “Convertible Debenture”) issuable in an aggregate principal amount of up to $100,000,000, which Convertible Debentures will be convertible into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”) (as converted, the “Conversion Shares”), as amended on August 13, 2025 by Amendment No. 1 to the Secured Convertible Debenture Purchase Agreement, and on October 28, 2025 by Amendment No. 2 to the Secured Convertible Debenture Purchase Agreement together, hereinafter referred to as the “Debenture Purchase Agreement”). Further to this, on November 4, 2025, the Company entered into a certain Amendment No. 3 to the Debenture Purchase Agreement (the “Third Amendment”) with Yorkville. The Third Amendment further amends the Debenture Purchase Agreement, adding additional closing conditions with no material terms amended.

Further to this, on November 4, 2025 (the “First Closing Date”), the Company issued an initial tranche of Convertible Debenture to Yorkville with a principal amount of $25,000,000 (the “First Convertible Debenture”). The First Convertible Debenture will mature on November 4, 2027, and will accrue interest at the rate of 4.00% per annum, which will increase to 18.00% per annum upon the occurrence of an event of default, until such event of default is cured. The principal must be paid in cash on the maturity date or earlier upon acceleration or conversion. Interest shall be provided in cash or, at the election of the Company, in kind through the issuance of Conversion Shares upon conversion of the First Convertible Debenture in accordance with the terms thereof. The First Convertible Debenture provides that the Investor may convert all or any portion of the principal amount of the Convertible Debenture, together with any accrued and unpaid interest thereon, at a conversion price equal to the lower of (i) $6.016 per Common Stock; a fixed price per share equal to 125% of the volume-weighted average price (“VWAP”) of the Common Stock on November 3, 2025, be subject to a one-time, downward only reset equal to 125% of the average of the daily VWAP for the Common Stock during the five consecutive trading days ending on and including the 30th trading day following the effectiveness of the registration statement registering the resale of the Conversion Shares as described below (the “Resale Registration Statement”), and (ii) 97.0% of the lowest daily VWAP for the Common Stock during the three trading days immediately preceding the applicable conversion date or other date of determination, subject to a floor price equal to $4.00 per Common Stock, in each case subject to adjustment as provided in the Convertible Debenture, including adjustments for stock splits, dividends, and other customary anti-dilution provisions. The First Convertible Debenture resulted in gross proceeds to the Company of approximately $24,000,000, representing 96.0% of the principal amount of each Convertible Debenture.

The Company has the option to prepay, in part or in whole, the outstanding principal and interest under the First Convertible Debenture prior to the maturity date, plus a prepayment premium of 10% of the principal amount of the applicable First Convertible Debenture, provided that the Company delivers at least ten trading days’ prior written notice of such prepayment, during which period the holder retains the right to convert all or any portion of the First Convertible Debenture. The First Convertible Debenture also provide for certain rights of the holder in the event the Company issues additional securities or incurs additional indebtedness, subject to the covenants set forth in the transaction documents. Standard events of default are included in the First Convertible Debenture, pursuant to which the holder may declare the First Convertible Debenture immediately due and payable and exercise other remedies, including the right to foreclose on the collateral securing the obligations. The Debenture Purchase Agreement also contains customary representation and warranties of the Company and the Investor, indemnification obligations of the Company, termination provisions, and other obligations and rights of the parties. The Investor shall not have the right to convert any portion of the First Convertible Debenture if, after giving effect to such conversion, the Investor, together with its affiliates, would beneficially own more than 4.99% of the outstanding Common Stock immediately following such conversion, as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules promulgated thereunder.

Yorkville may purchase the second Secured Convertible Debenture in a principal amount of $25,000,000 following the satisfaction of the conditions set forth in Sections 6, 7(a) and 7(b) of the Debenture Purchase Agreement (the “Second Closing”), and certain additional Secured Convertible Debentures in an aggregate principal amount of up to $50,000,000, upon mutual agreement of the parties, which agreement may be withheld in either parties sole discretion.

Guaranty and Security Agreement

On the First Closing Date, pursuant to the terms of the Debenture Purchase Agreement, the Company, certain parties thereto from time to time as grantors, including the Company’s subsidiaries, and Yorkville entered into (i) a U.S. Guaranty and Security Agreement (the “US Guaranty”) among the Company, certain subsidiaries and YA II PN, LTD., as collateral agent, and (ii) a Canadian Guarantee and Security Agreement (the “Canadian Guaranty”) among the Company, Streamex and certain other Canadian subsidiaries and YA II PN, LTD., as collateral agent, together with related control agreements, collateral access agreements and perfection filings under the UCC and PPSA (as defined in the transaction documents), as applicable, in favor of Yorkville in its capacity as collateral agreement with respect to the Company’s obligations under the Debenture Purchase Agreement and the First Convertible Debenture.

Lock-Up Agreement

Prior to First Closing Date, each of the directors, officers, and certain shareholders of the Company entered into a Lock-Up Agreement (collectively, the “Lock-Up Agreements”). Pursuant to the Lock-Up Agreements, each such party agreed that the shares of Company Common Stock (including securities convertible into or exercisable or exchangeable for Company Common Stock) held by them or received in connection with the Merger (as defined in the Debenture Purchase Agreement) are subject to transfer restrictions for 180 days through the Closing, in each case subject to certain exceptions.

Registration Rights Agreement

On the First Closing Date, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) with Yorkville pursuant to which the Company has agreed to register for resale the Conversion Shares under the Securities Act of 1933, as amended (the “Securities Act”).
