Dated as of March 3, 2026

Capstone Companies, Inc., a Florida corporation subject to the reporting requirements of the Securities Exchange Act of 1934, (the “Maker”), promises to pay to the order of eBliss Global, Inc., a private Delaware corporation, (“Payee”) the principal sum of TWO HUNDRED FIFTY THOUSAND U.S. Dollars (U.S. $250,000.00), or such lesser amount as shall have been received by Maker from Payee in good funds on deposit, (the “Principal”) and shall remain unpaid under this Note on the “Maturity Date” (as defined in Section 1(a) below) in lawful money of the United States of America, and on the terms and conditions described below. The Principal shall be deposited by wire transfer to Maker’s U.S. corporate bank account (“Maker’s Account”) by Payee on the date that this Note is signed by Maker and Payee or within two (2) business days thereafter. All payments of amounts owed under this Note by Maker to the Payee shall be paid by wire transfer to the U.S. corporate bank account designed in writing by Payee (“Payee’s Account”) and shall be paid in the name of the Payee.

1. Principal; Certain Defined Terms. (a) Principal. The entire unpaid Principal and all interest accrued thereon (as defined in Section 2 below) shall be due and payable in full on the first annual anniversary of the date on which the Principal is received by the Maker in good funds on deposit in its Maker’s Account (the “Maturity Date”).

(b) Certain Defined Terms. “Affiliate” has the meaning set forth in 17 Code of Federal Regulations §230.405. “Business day” means any day on which the banks in Broward County, Florida are open for business on regular operating hours. “Funding Date” is the date on which the Maker receives the Principal in good funds on deposit in Maker’s Account. “Business Transaction” means a transaction or event in which a Person obtains control of the Maker, which transaction or event includes, without limitation: a reorganization, merger or consolidation; issuance or exchange of Maker’s securities that exceeds thirty percent (30%) of the issued and outstanding shares of capital stock of Maker with voting rights (including in the calculation the full conversion of any securities of Maker into voting securities of the Maker); a sale or other disposition of all or substantially all of the assets; a joint venture or strategic alliance for development of a business line; or a transaction or an event causing the directors of the Maker as of the Funding Date to no longer constitute a majority of the Maker’s Board of Directors (other than as the result of election of directors by shareholders at an annual meeting of Maker’s Common Stock shareholders). “Control” means either owning or controlling fifty percent (50%) or more of the outstanding voting securities, or having the present, contractual power or other authority to designate fifty percent (50%) or more of the directors or equivalent positions, or controlling the executive management of an entity. “Person” means any individual, group, corporation, partnership, limited liability company, business trust, other trust, association, organization, or other entity, including a group within the meaning of Sections 13(d) or 14(d)(2) of the Securities Exchange Act of 1934 and rules thereunder, who is not the Payee or any of its respective affiliates or the Maker.

2. Interest on Principal. Simple annual interest shall accrue on the unpaid Principal at SEVEN PERCENT (7%)(accrued interest on Principal shall be referred to as the “Interest”).

3. Pre-Payment; Application of Payments; Secondary Liability. The unpaid Principal and Interest may be prepaid at any time without penalty or charge. All amounts paid under this Note shall be applied first to payment in full of any costs incurred in the collection of any amount due under this Note, including, without limitation, reasonable attorney’s fees awarded by a court, then to the payment in full of any late charges, then to reduction of any accrued and unpaid Interest and finally to the reduction of the unpaid Principal. Under no circumstances shall any individual, including but not limited to any officer, director, employee, shareholder or agent of the Maker, be obligated personally for any obligations or liabilities of the Maker under this Note.

(c) Involuntary Bankruptcy. The entry of a decree or order for relief by a court having competent jurisdiction 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.

(d) Deregistered. The Maker no longer has a class of equity securities registered under Section 12(g) or Section 12(b) of the Securities Exchange Act of 1934, or its shares of Common Stock are no longer quoted on a tier of The OTC Market Group, and the Maker fails to remedy an Event of Default under this Section 4(d) within sixty (60) days after the occurrence of the Event of Default.

5. Remedies. (a) Upon the occurrence of an Event of Default specified in Section 4(a) above, then, subject to any cure period, Payee shall by written notice to Maker declare the unpaid Principal and Interest to be immediately due and payable, whereupon the unpaid Principal, unpaid and accrued Interest, and all other amounts payable under this Note, 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 4(b) or 4(c) or 4(d), and subject to any cure period, the unpaid Principal and unpaid and accrued Interest, and all other sums payable with regard to this Note, shall become immediately due and payable, in all cases without any action or notice on the part of the Payee.

7. Corporate Debt. The Maker agrees and attests that the Principal is a valid corporate debt of the Maker and that this Note and the loan thereunder have been approved by the Maker’s Board of Directors. Principal shall be used as general working capital of the Maker. The Note is an unsecured corporate obligation of Maker.

8. No Shop. (a)(i) Period. For a period of ninety (90) consecutive days from the Funding Date ("Exclusivity Period"), Maker agrees not to, directly or indirectly, initiate, solicit, encourage, or engage in discussions or negotiations with, or provide any information to, any Person (other than the Payee and its authorized agents and affiliates) regarding any proposal or offer for a Business Transaction (a "Third Party Proposal"). (ii) This Section 8 shall have no force or effect upon the expiration of the Exclusivity Period, which expiration date shall commence at 12:01 a.m., local Miami, Florida time, on the day immediately following the last day of the Exclusivity Period, or upon the signing a definitive written agreement by the Maker and Payee that expressly supersedes this Note and is executed prior to the expiration of the Exclusivity Period, or the Maker entering into an agreement to consummate a “Superior Proposal” (as defined in Section 8(d) below).

(b) Notification of Third Party Proposals. Maker shall notify the Payee in writing within two (2) business days after receipt of any Third Party Proposal during Exclusivity Period, or any request for information or inquiry that could reasonably be expected to lead to a Third Party Proposal. This written notification shall include the identity of the third party and the terms and conditions of any Third Party Proposal, or related request or inquiry.

(c) Cessation of Existing Discussions. Maker agrees to cease any existing discussions or negotiations with any third parties conducted heretofore with respect to any pending Third Party Proposal upon signing of this Note by the Maker and Payee.

(d) Fiduciary Out. Notwithstanding the foregoing provisions of this Section 8, and if the Maker and Payee have not signed a written letter of intent or definitive written agreement for a Business Transaction by the sixtieth (60th) consecutive day of the Exclusivity Period, the Board of Directors of the Maker (“Board”) may, in response to a bona fide, written and unsolicited Third Party Proposal that the independent directors of the Board determines in good faith, after consultation with the Maker’s financial advisor and outside legal counsel, or the financial advisor and outside legal counsel for an independent director committee, is likely to lead to a “Superior Proposal” (as defined in Section 8(e) below), engage in discussions or negotiations with, and provide non-public information to, the third party tendering the Superior Proposal, subject to a confidentiality agreement no less restrictive than those contained in the Non-Disclosure Agreement between the Maker and Payee, dated November 16, 2025 or thereabouts. Consideration, acceptance and consummation of a Superior Proposal by Maker shall not constitute a breach of this Section 8.

(e) Defined. "Superior Proposal" is defined as a bona fide written, unsolicited offer by a third party for any Business Transaction on terms and conditions that the independent directors of the Board determine in their good faith judgment (after consultation with Maker’s or an independent director committee’s financial advisor and outside legal counsel), taking into account all legal, financial, regulatory, and other aspects of the Superior Proposal and the proposed acquirer, to be more favorable to the Maker’s public shareholders than any pending written proposal or offer for a Business Transaction by the Payee or by any of its affiliates.

(f) No Obligation to Consummate a Business Transaction. Neither this Note nor any provision herein shall obligate the Maker or Payee to negotiate or enter into a definitive agreement or letter of intent, or other legally binding agreement for, or to negotiate or consummate, any Business Transaction. No legally binding agreement for a Business Transaction, and no letter of intent by the Maker and Payee for a Business Transaction, exists as of the Funding Date and there is no assurance that any such agreement or letter of intent will ever exist, be negotiated or consummated, or that any Business Transaction will occur.

While Maker will endeavor to solicit Payee’s comments on the Form 8-K and related public disclosures therein prior to filing with the SEC or making the related public disclosures, the Maker shall be entitled to file the Form 8-K and make related public disclosures without the consent or review of the Payee. However, Maker and Payee agree that no press release about this Note will be issued without the prior written consent of the Maker and Payee.

13. Severability. If any provision of this Note is deemed to be invalid by reason of the operation of law, or by reason of the interpretation placed thereon by any administrative agency or any court, the Maker and Payee shall negotiate an equitable adjustment in the provisions of the same in order to effect, to the maximum extent permitted by law, the purpose of this Note and the validity and enforceability of the remaining provisions, or portions or applications thereof, shall not be affected thereby and shall remain in full force and effect.
