JOINDER AND THIRD LOAN MODIFICATION AGREEMENT

This Joinder and Third Loan Modification Agreement (this “Agreement”) is entered into as of January 12, 2023, by and among (a) SILICON VALLEY BANK, a California corporation, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at 505 Howard Street, 3rd Floor, San Francisco, California 94105 (“Bank”), (b) MOLEKULE, INC., a Delaware corporation, whose address is 1301 Folsom Street, San Francisco, California 94103 (“Existing Borrower”), and (c) MOLEKULE GROUP, INC. (F/K/A AEROCLEAN TECHNOLOGIES, INC.), a Delaware corporation, whose address is 10455 Riverside Drive, Palm Beach Gardens, Florida 33410 (“New Borrower”). New Borrower and Existing Borrower, are hereinafter jointly and severally, individually and collectively, “Borrower”.

1.DESCRIPTION OF EXISTING INDEBTEDNESS AND OBLIGATIONS. Among other indebtedness and obligations which may be owing by Existing Borrower to Bank, Existing Borrower is indebted to Bank pursuant to a loan arrangement dated as of March 22, 2021, evidenced by, among other documents, a certain Mezzanine Loan and Security Agreement dated as of March 22, 2021, between Existing Borrower and Bank, as amended by a certain First Loan Modification Agreement dated as of May 19, 2022, as further amended by a certain Second Loan Modification Agreement dated as of October 1, 2022 (the “Loan Agreement”). Capitalized terms used but not otherwise defined herein shall have the same meaning as in the Loan Agreement.

2.JOINDER TO LOAN AGREEMENT. New Borrower hereby joins the Loan Agreement and each of the Loan Documents, and agrees to comply with and be bound by all of the terms, conditions and covenants of the Loan Agreement and Loan Documents, as if it were originally named a “Borrower” therein. Without limiting the generality of the preceding sentence, New Borrower agrees that it will be jointly and severally liable, together with the Existing Borrower, for the payment and performance of all obligations and liabilities of Borrower under the Loan Agreement, including, without limitation, the Obligations. Each Borrower hereby appoints the other as agent for the other for all purposes hereunder. Each Borrower hereunder shall be obligated to repay all Credit Extensions made pursuant to the Loan Agreement, regardless of which Borrower actually receives said Credit Extension, as if each Borrower hereunder directly received all Credit Extensions.

3.SUBROGATION AND SIMILAR RIGHTS. Each Borrower waives any suretyship defenses available to it under the Code or any other applicable law. Each Borrower waives with respect to all Obligations of such Borrower and the Obligations of any other Borrower any right to require Bank to: (i) proceed against any other Borrower or any other person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank may exercise or not exercise any right or remedy it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale to the extent permitted by law) without affecting any Borrower’s liability. Notwithstanding any other provision of this Agreement, the Loan Agreement or other Loan Documents, each Borrower irrevocably agrees that, until the Loan Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations, any other obligations which by their terms are to survive the termination of the Loan Agreement, and any Obligations under Bank Services Agreements that are cash collateralized in accordance with Section 4.1 of the Loan Agreement) have been satisfied, it shall not exercise any rights that it may have at law or in equity (including, without limitation, any law subrogating Borrower to the rights of Bank under the Loan Agreement or pursuant to any agreement providing for indemnification, reimbursement or any other similar arrangement) to seek contribution, indemnification or any other form of reimbursement from any other Borrower, or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any payment made by Borrower with respect to the Obligations in connection with the Loan Agreement or otherwise and all rights that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by Borrower with respect to the Obligations in connection with the Loan Agreement or otherwise. If any payment is made to a Borrower in contravention of this Section 3, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly delivered to Bank for application to the Obligations, whether matured or unmatured.

4.GRANT OF SECURITY INTEREST. To secure the prompt payment and performance of all of the Obligations, New Borrower hereby grants to Bank a continuing lien upon and security interest in the Collateral set forth on Exhibit A of the Loan Agreement (as if such Collateral were deemed to pertain to the assets of New Borrower) of New Borrower, whether now owned or existing or hereafter created, acquired, or arising, and wherever located. New Borrower further covenants and agrees that by its execution hereof it shall provide all such

information, complete all such forms, and take all such actions, and enter into all such agreements, in form and substance reasonably satisfactory to Bank that are reasonably requested by Bank or necessary in order to grant a valid, perfected first priority security interest to Bank in the Collateral (subject only to Permitted Liens that are permitted pursuant to the terms of the Loan Agreement to have superior priority to Bank’s Lien in the Loan Agreement). New Borrower hereby authorizes Bank to file financing statements, without notice to Borrower, with all appropriate jurisdictions in order to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code, and any such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Bank’s reasonable discretion.

5.REPRESENTATIONS AND WARRANTIES. New Borrower hereby represents and warrants to Bank that all representations and warranties in the Loan Documents made on the part of Existing Borrower are true and correct on the date hereof with respect to New Borrower, with the same force and effect as if New Borrower was named as “Borrower” in the Loan Documents in addition to Existing Borrower.

6.DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by (a) the Collateral as defined in the Loan Agreement, (b) the Intellectual Property Collateral as defined in a certain Intellectual Property Security Agreement dated as of March 22, 2021 between Existing Borrower and Bank, as amended by a certain First Amendment to Intellectual Property Security Agreement dated as of the date of May 19, 2022, and as further amended by a certain Second Amendment to Intellectual Property Security Agreement dated as of the date of this Agreement (as amended, the “Existing Borrower Intellectual Property Security Agreement”), and (c) the Intellectual Property Collateral as defined in a certain Intellectual Property Security Agreement dated as of the date of this Agreement between New Borrower and Bank (the “New Borrower Intellectual Property Security Agreement”) (together with any other collateral security granted to Bank, as amended, the “Security Documents”). Hereinafter, the Security Documents, together with all other documents evidencing or securing the Obligations shall be referred to as the “Existing Loan Documents”.
