This INTELLECTUAL PROPERTY SECURITY AGREEMENT (“IP Security Agreement”), dated as of August 14, 2024, is made by REALPHA TECH CORP., a Delaware corporation (“Debtor”), in favor of STREETERVILLE CAPITAL, LLC, a Utah limited liability company (the “Secured Party”).

A. Debtor issued to Secured Party a certain Secured Promissory Note of even date herewith, as may be amended from time to time (the “Note”), pursuant to a certain Note Purchase Agreement of even date herewith by and between Debtor and Secured Party (the “Purchase Agreement”).

B. In order to induce Secured Party to extend the credit evidenced by the Note, Debtor has agreed to enter into that certain Security Agreement of even date herewith by and between Debtor and Secured Party (the “Security Agreement”) and to grant Secured Party a security interest in certain “Collateral” as defined in the Security Agreement.

C. Under the terms of the Security Agreement, Debtor has granted to the Secured Party a security interest in, among other property, certain intellectual property of the Debtor, and has agreed to execute and deliver this IP Security Agreement for recording with governmental authorities, including, but not limited to, the United States Patent and Trademark Office.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Grant of Security. Debtor hereby pledges and grants to Secured Party a security interest in and to all of the right, title, and interest of Debtor in, to, and under the following (the “IP Collateral”):

(a) the patents and patent applications set forth on Schedule 1 hereto and all reissues, divisions, continuations, continuations-in-part, renewals, extensions, and reexaminations thereof, and amendments thereto;

(b) the trademark registrations and applications set forth on Schedule 1 hereto, together with the goodwill connected with the use thereof and symbolized thereby, and all extensions and renewals thereof;

(c) all rights of any kind whatsoever of Debtor accruing under any of the foregoing provided by applicable law of any jurisdiction, by international treaties and conventions and otherwise throughout the world;

(d) any and all royalties, fees, income, payments, and other proceeds now or hereafter due or payable with respect to any and all of the foregoing; and

(e) any and all claims and causes of action with respect to any of the foregoing, whether occurring before, on, or after the date hereof, including all rights to and claims for damages, restitution, and injunctive and other legal and equitable relief for past, present, and future infringement, dilution, misappropriation, violation, misuse, breach, or default, with the right but no obligation to sue for such legal and equitable relief and to collect, or otherwise recover, any such damages.

2. Recordation. Debtor authorizes the Commissioner for Patents and the Commissioner for Trademarks in the United States Patent and Trademark Office and the officials of corresponding entities or agencies in any applicable jurisdictions to record and register this IP Security Agreement upon request by the Secured Party.

3. Loan Documents. This IP Security Agreement has been entered into pursuant to and in conjunction with the Security Agreement, the Purchase Agreement, the Note and all other documents related thereto and entered into in connection therewith (the “Loan Documents”), which are hereby incorporated by reference. The provisions of the Loan Documents shall supersede and control over any conflicting or inconsistent provision herein. The rights and remedies of the Secured Party with respect to the IP Collateral are as provided by the Loan Documents and nothing in this IP Security Agreement shall be deemed to limit such rights and remedies.

4. Execution in Counterparts. This IP Security Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

5. Successors and Assigns. This IP Security Agreement will be binding on and shall inure to the benefit of the parties hereto and their respective permitted successors and assigns. This IP Security Agreement may be assigned by Secured Party to its affiliates that are permitted assignees of the Note, upon prior written notice to Debtor, without the need to obtain Debtor’s consent thereto, provided that any such assignee agrees in writing to by bound by the terms of all Transaction Documents (as defined in the Purchase Agreement) as though an original party thereto. Except as set forth above, neither Secured Party nor Debtor may assign its rights or obligations under this IP Security Agreement or delegate its duties hereunder, whether directly or indirectly, without the prior written consent of the other party, and any such attempted assignment or delegation shall be null and void.

6. Governing Law; Arbitration. This IP Security Agreement and any claim, controversy, dispute, or cause of action (whether in contract or tort or otherwise) based upon, arising out of, or relating to this IP Security Agreement and the transactions contemplated hereby and thereby shall be governed by, and construed in accordance with, the laws of the United States and the State of Utah, without giving effect to any choice or conflict of law provision or rule (whether of the State of Utah or any other jurisdiction), and will be subject to the Arbitration Provisions (as defined in the Purchase Agreement) attached as an exhibit to the Purchase Agreement.
