WHEREAS, the Note is secured by that certain Security Agreement dated August 20, 2025, by and between Marizyme, as debtor, and Seller, as secured party (the “Security Agreement”), granting Seller a security interest in substantially all assets of Marizyme (the “Collateral”);

WHEREAS, Seller’s name was changed from Qualigen Therapeutics, Inc. to AIxCrypto Holdings, Inc. effective November 14, 2025, pursuant to a Certificate of Amendment to the Certificate of Incorporation filed with the Delaware Secretary of State, a copy of which is attached hereto as Exhibit C;

WHEREAS, Buyer is a newly formed New York limited liability company organized for the purpose of acquiring the assets of Marizyme;

WHEREAS, Seller desires to sell, assign, and transfer to Buyer, and Buyer desires to purchase and accept from Seller, all of Seller’s right, title, and interest in and to the Note, the Security Agreement, and all related creditor rights, on the terms and conditions set forth herein;

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

ARTICLE 1

DEFINITIONS

1.1 “Note Package” means, collectively: (a) the Note; (b) the Co-Development Note (as defined in Section 1.5); (c) the Security Agreement; (d) all UCC financing statements filed in connection with the Security Agreement; (e) any and all rights of Seller as a secured creditor of Marizyme with respect to the Collateral; and (f) all rights to collect, enforce, or receive payment of the Note Obligations and any amounts due under the Co-Development Note.

1.2 “Net Revenue” means, with respect to any product or technology commercialized by CABG SPV (as defined in Section 3.3) utilizing the assets of Marizyme, gross revenue actually received by CABG SPV from third parties in arm’s-length transactions, less only the royalties owed by CABG SPV to the original owner of DuraGraft pursuant to any pre-existing license or royalty agreement to which CABG SPV is bound. For the avoidance of doubt, no other deductions, offsets, returns, chargebacks, taxes, or expenses shall reduce Net Revenue unless expressly agreed in writing by Seller.

1.3 “Royalty Cap” means Five Million Six Hundred Seventy-One Thousand One Hundred Forty-Two Dollars ($5,671,142), representing the approximate present value of the Note Obligations as of the date of this Agreement. For the avoidance of doubt, the Royalty Cap applies solely to royalty payments on Net Revenue under Section 3.2 and does not limit or cap any Investment Return or other amounts payable to Seller under the Co-Development Note.

1.4 “Co-Development Note” means that certain Co-Development Note dated April 11, 2024, by and between Marizyme and Seller (as successor to Qualigen Therapeutics, Inc.), as amended by Amendment No. 1 to Co-Development Note dated August 6, 2024, providing for a funding amount of $1,750,000 and an Investment Return payable to Seller based on the commercial success of the DuraGraft product, together with all rights of Seller thereunder.

ARTICLE 2

PURCHASE AND SALE; ASSIGNMENT

2.1 Purchase and Sale. Subject to the terms and conditions of this Agreement, at the Closing, Seller hereby sells, assigns, transfers, and conveys to Buyer, and Buyer hereby purchases and accepts from Seller, all of Seller’s right, title, and interest in and to the Note Package, free and clear of any liens, claims, or encumbrances created by Seller or, to Seller’s actual knowledge, consented to by Seller (other than those existing under the Note Package itself).

2.2 Quitclaim Basis. THE ASSIGNMENT OF THE NOTE PACKAGE IS MADE ON A QUITCLAIM BASIS EXCEPT AS EXPRESSLY SET FORTH IN ARTICLE 4A HEREOF. SELLER MAKES NO REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO: (a) THE COLLECTABILITY OR ENFORCEABILITY OF THE NOTE OR ANY NOTE OBLIGATION; (b) THE PERFECTION, PRIORITY, OR SUFFICIENCY OF ANY SECURITY INTEREST GRANTED UNDER THE SECURITY AGREEMENT OR ANY FINANCING STATEMENT FILED IN CONNECTION THEREWITH; (c) THE FINANCIAL CONDITION OR SOLVENCY OF MARIZYME; OR (d) THE VALUE OF ANY COLLATERAL. SUBJECT TO ARTICLE 4A HEREOF, BUYER ACCEPTS THE NOTE PACKAGE IN ITS “AS-IS, WHERE-IS” CONDITION AND ASSUMES ALL RISKS ASSOCIATED THEREWITH.

2.3 Assumption. Buyer hereby assumes all obligations of Seller as holder of the Note Package arising after the Closing Date, including any obligations of a secured creditor under applicable law with respect to the Collateral. Seller retains no liability with respect to the Note Package arising after the Closing Date.

2.4 Notification to Marizyme. Promptly following the Closing, Buyer shall provide written notice to Marizyme of the assignment of the Note and the Security Agreement, in form and substance reasonably acceptable to Seller. Seller shall cooperate with Buyer in connection with any such notification.

ARTICLE 3

CONSIDERATION

3.1 Cash Consideration. At the Closing, Buyer shall pay to Seller, by wire transfer of immediately available funds to the account designated by Seller in writing prior to the Closing, the sum of One Hundred Thousand Dollars ($100,000) (the “Cash Consideration”).

3.2 Royalty. Following the Closing, Buyer shall pay to Seller a royalty equal to ten percent (10%) of Net Revenue on all cumulative Net Revenue exceeding Twenty Million Dollars ($20,000,000) (the “Royalty Threshold”). The aggregate royalty payments under this Section 3.2 shall not exceed the Royalty Cap. Once cumulative royalty payments to Seller equal the Royalty Cap, no further royalty shall be owed. Royalties shall be calculated and paid quarterly, within thirty (30) days following the end of each calendar quarter in which Net Revenue exceeds the Royalty Threshold on a cumulative basis. Each quarterly payment shall be accompanied by a written report setting forth in reasonable detail the calculation of Net Revenue and the royalty payment due.

3.3 Equity Interest. At the Closing, or as soon as practicable thereafter but in no event later than 60 days following the Closing, Buyer shall, or shall cause another entity organized by Buyer to, acquire and commercialize the assets of Marizyme (such acquisition, the “Acquisition” and such acquiring entity, the “CABG SPV”). Within 30 days after the Acquisition, Buyer shall issue or cause to be issued to Seller a membership interest equal to four and ninety-nine hundredths percent (4.99%) of the outstanding membership interests in the CABG SPV (the “Equity Interest”), provided that nothing herein shall obligate Buyer or CABG SPV to act (or refrain from acting) other than in a good faith and commercially reasonable manner. The Equity Interest shall be evidenced by an executed joinder to the CABG SPV’s operating agreement and a corresponding membership interest certificate or written confirmation of membership. The terms of the Equity Interest shall be no less favorable than those applicable to any other member of the CABG SPV holding a comparable membership interest. For the avoidance of doubt, the 4.99% interest is calculated on a fully diluted basis as of the date of issuance. If Buyer fails to deliver evidence of the Equity Interest to Seller within thirty (30) days of the Closing (subject to a five (5) business day cure period after written notice from Seller specifying the breach), Seller shall be entitled to specific performance of this Section 3.3 in any court of competent jurisdiction without the requirement of posting any bond or other security, the parties acknowledging that the Equity Interest is unique in nature and that monetary damages alone would be an inadequate remedy. If, within one hundred eighty (180) days following the Closing Date, the assets of Marizyme (or substantially all of them) are acquired by Buyer or any affiliate of Buyer through any structure other than the CABG SPV, the Equity Interest shall be issued by the entity holding such assets on the terms set forth herein, and references in this Agreement to the CABG SPV shall be deemed to refer to such entity.

3.4 Preemptive Right. If the CABG SPV proposes to issue any new membership interests or other equity securities (each a “New Issuance”), Buyer shall provide Seller with written notice of the proposed New Issuance at least 15 business days prior to the closing of such New Issuance, setting forth in reasonable detail the number and type of interests to be issued, the price, and the other material terms. Seller shall have the right, exercisable by written notice to Buyer within 10 business days of receipt of such notice, to purchase up to its pro rata share of the New Issuance (based on Seller’s then-current percentage of outstanding membership interests in the CABG SPV) on the same terms and conditions as those offered to other investors, for the purpose of maintaining its percentage interest in the CABG SPV on a fully diluted basis. If Seller does not exercise this right within such 10 business day period, Seller shall be deemed to have waived its pre-emptive right with respect to that New Issuance only. This right shall apply to each subsequent New Issuance on the same terms.

3.5 Transfer of Equity Interest. Seller may freely sell, assign, transfer, or otherwise dispose of the Equity Interest or any portion thereof to any third party without the consent of Buyer, subject only to applicable federal and state securities laws, and provided that any such third party shall be reasonably acceptable to Buyer. Prior to any transfer of all or any portion of the Equity Interest to a third party, Seller shall provide Buyer with written notice of the proposed transfer, including the proposed transferee and transfer terms. Buyer shall have 10 business days to elect to purchase the offered interest at the same price and on the same terms. If Buyer does not exercise this right, Seller may proceed with the transfer to the identified transferee on terms no more favorable than those offered to Buyer. Buyer shall cooperate with Seller in connection with any such transfer, including by executing and delivering such instruments of transfer, consents, and other documents as may be reasonably requested by Seller or a transferee to effect such transfer, and by promptly updating the CABG SPV’s records to reflect the transfer. Any transferee of the Equity Interest shall succeed to Seller’s rights with respect to the transferred interest, including the pre-emptive right under Section 3.6 and the registration rights under Section 3.8. Notwithstanding the foregoing, no right of first refusal under this Section 3.7 shall apply to (a) any transfer of the Equity Interest by Seller to an affiliate of Seller, or (b) any pledge or grant of a security interest in the Equity Interest by Seller to a bona fide lender; provided, however, that any such transfer, pledge or grant shall be null and void without the prior written consent of Buyer, not to be unreasonably withheld.

3.6 Registration Rights. If the CABG SPV or any successor entity converts to a corporation or otherwise becomes subject to the Securities Act of 1933 (as amended) in connection with a public offering or otherwise, Buyer shall use commercially reasonable efforts to cause Seller to be granted piggyback registration rights with respect to the Equity Interest, entitling Seller to include the Equity Interest (or any securities into which it is converted) in any registration statement filed by the CABG SPV or its successor with the Securities and Exchange Commission, subject to customary underwriter cutback provisions and market standoff restrictions of no more than one hundred eighty (180) days. Buyer shall notify Seller in writing no later than thirty (30) days prior to filing any such registration statement to allow Seller to exercise its piggyback rights. In addition, if the CABG SPV or any successor entity undertakes a sale, merger, or other change of control transaction, Buyer shall use commercially reasonable efforts to cause Seller to receive the same per-unit consideration in respect of the Equity Interest as other holders of equivalent membership interests or shares.

3.7 No Other Consideration. The Cash Consideration, the Royalty, and the Equity Interest constitute the entire consideration payable by Buyer to Seller in connection with the transactions contemplated by this Agreement. No other payment is owed by either party to the other, except as expressly set forth herein.
