PROMISSORY NOTE

Principal Amount:  Up to U.S.$785,000.00

Issuance Date: February 19, 2026

FOR VALUE RECEIVED and subject to the terms and conditions set forth herein, Soulpower Acquisition Corporation, a Cayman Islands exempted company (“Maker”), promises to pay to Soulpower Management LLC, a limited liability company incorporated in Delaware (“Payee”), or order, the principal sum of Seven Hundred Eighty- Five Thousand U.S. Dollars (U.S.$785,000.00) or such lesser amount as shall have been advanced by Payee to Maker and shall remain unpaid under this Note on the Maturity Date (as defined below) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by Maker to such account as Payee may from time to time designate by written notice in accordance with the provisions of this Note.

1. Principal. The entire unpaid principal balance of this Note shall be due and payable in full on the earlier of (i) the effective date of an initial business combination or (ii) the liquidation date of the Maker (the “Maturity Date”), unless accelerated upon the occurrence of an Event of Default (as defined below). The principal balance may be prepaid at any time by Maker, at its election and without penalty. Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of Maker, be obligated personally for any obligations or liabilities of Maker hereunder.

2. Drawdown Requests. Maker and Payee agree that Maker may request, from time to time, up to Seven Hundred Eighty Five Thousand U.S. Dollars (U.S.$785,000.00) in drawdowns under this Note to be used for certain costs and expenses (the “Uses”). The principal of this Note may be drawn down from time to time prior to the Maturity Date upon request from Maker to Payee (each, a “Drawdown Request”). Payee shall fund each Drawdown Request no later than three (3) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns outstanding under this Note at any time may not exceed Seven Hundred Eighty-Five Thousand U.S. Dollars (U.S.$785,000.00). No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.

3. Interest. Interest shall accrue on the outstanding principal balance of this Note at a flat-rate interest charge of 22%. All accrued interest shall be payable in full at the Maturity Date, unless earlier prepaid. For the avoidance of doubt, the interest rate shall be fixed regardless of the duration of the loan and the total amount owed at the Maturity Date (or earlier prepayment, if any) shall be equal to the product of (i) 1.22 multiplied by (ii) the outstanding principal balance.

4. Non-Convertible. This Note is not, and shall not be, convertible into equity securities, other securities, or any other ownership interests of the Maker, whether in connection with an initial business combination or otherwise.

5. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

6. Events of Default. The following shall constitute an event of default (“Event of Default”):

(a) Failure to Make Required Payments. Failure by Maker to pay the principal amount and unpaid interest due pursuant to this Note on the Maturity Date.

(b) Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.

(c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of sixty (60) consecutive days.

7. Remedies.

(a) Upon the occurrence of an Event of Default specified in Section 6(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable thereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

(b) Upon the occurrence of an Event of Default specified in Sections 6(b) or 6(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of Payee.

8. Waivers. Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor, protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee.

9. Unconditional Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting Maker’s liability hereunder.
