Amendmentto Secured Convertible Debenture Purchase Agreement and Second 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, November 6, 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”), 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, on October 28, 2025 by Amendment No. 2 to the Secured Convertible Debenture Purchase Agreement, on November 4, 2025 by Amendment No. 3 to the Secured Convertible Debenture Purchase Agreement together, hereinafter referred to as the “Debenture Purchase Agreement”). Further to this, on December 17, 2025, the Company entered into a certain Amendment No. 4 to the Debenture Purchase Agreement (the “Fourth Amendment”) with Yorkville. The Fourth Amendment further amends the Debenture Purchase Agreement, amending certain prior closing conditions with no material terms amended.

Further to this, on December 17, 2025 (the “Second Closing Date”), the Company issued the second tranche of Convertible Debenture to Yorkville with a principal amount of $25,000,000 (the “Second Convertible Debenture”), on similar terms as the initial tranche of Convertible Debenture to Yorkville, dated November 4, 2025, as disclosed in our Prior Form 8-Ks. The Second Convertible Debenture will mature on December 17, 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 Second Convertible Debenture in accordance with the terms thereof. The Second 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 Second 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 Second Convertible Debenture prior to the maturity date, plus a prepayment premium of 10% of the principal amount of the applicable Second 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 Second Convertible Debenture. The Second 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 Second Convertible Debenture, pursuant to which the holder may declare the Second 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 Second 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.

The foregoing descriptions of the Second Convertible Debenture, and the Fourth Amendment, do not purport to be complete and are qualified in their entirety by reference to the full text of such documents, which are filed or referenced hereof as Exhibits 4.1, and 10.1 respectively, and are incorporated herein by reference.

Item 2.03Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information contained in Item 1.01 is incorporated herein by reference.

Item 3.02Unregistered Sales of Equity Securities.

The information contained in Item 1.01 is incorporated herein by reference. The issuance of the Second Convertible Debenture was, and the Conversion Shares issuable upon conversion of the Second Convertible Debenture will be, exempt from registration pursuant to Section 4(a)(2) of the Securities Act. Yorkville represented to the Company that it is an “accredited investor” as defined in Rule 501 of the Securities Act and that each of the Second Convertible Debenture and the Conversion Shares will be acquired for investment purposes and not with a view to, or for sale in connection with, any distribution thereof.
