SECTION 1.Authorization, Sale and Purchase of Note; Closing.

1.1Authorization of the Note. The Company has duly authorized the issuance and sale of $25.0 million aggregate principal amount of the Note in a private offering, pursuant to this Agreement, with interest (computed on the basis of a 360-day year comprised of twelve 30-day months) on the unpaid balance hereof at the rate of 8.00% per annum from the date hereof, payable quarterly in arrears on January 31, April 30, July 31, and October 31 each year, commencing on October 31, 2025 until the principal hereof shall have become due and payable.

1.3Optional Redemption. The Note may be redeemed in whole or in part at any time or from time to time at the Company’s option upon not less than 30 days nor more than 60 days prior written notice (e-mail shall suffice), at a redemption price equal to 100% of the then outstanding principal amount of the Note plus accrued and unpaid interest payments otherwise payable for the then-current quarterly interest period accrued to, but excluding, the date fixed for redemption.

SECTION 2.Representations and Warranties of the Buyer. Buyer severally represents and warrants to the Company, as of the date hereof and as of the Closing Date, as follows:

The Buyer was not formed or recapitalized for the specific purpose of acquiring any securities of the Company. This Agreement, when executed and delivered by the Buyer, shall constitute a valid and legally binding obligation of the Buyer, enforceable against the Buyer in accordance with its terms, except as rights to indemnity may be limited by federal or state securities laws or principles of public policy and subject to the qualification that the enforceability of the Buyer’s obligations hereunder may be limited by bankruptcy, fraudulent conveyance, insolvency, reorganization, receivership, moratorium, and other laws relating to or affecting creditors’ rights generally and by general equitable principles (including, without limitation, the availability of specific performance or injunctive relief and the application of concepts of materiality, reasonableness, good faith and fair dealing) regardless of whether enforcement is considered in a proceeding in equity or at law.

2.2Investment Purpose. The Note is being acquired by the Buyer for the Buyer’s own account for investment purposes only and not for resale or distribution in violation of applicable securities laws.

2.3No General Solicitation. The Buyer was offered the Note through private negotiations, not through any general solicitation or general advertising.

2.4Knowledge and Experience; Information. The Buyer: (a) is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”); (b) either alone or together with its representatives, has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Note and making an informed decision to so invest, and has so evaluated the risks and merits of such investment; (c) has the ability to bear the economic risks of this investment and can afford a complete loss of such investment; (d) understands the terms of and risks associated with the acquisition of the Note, including, without limitation, the risks associated with the industry in which the Company operates; (e) has had the opportunity to review the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and other publicly available financial information concerning the Company and such other disclosure regarding the Company, its business, its financial condition and its prospects as the Buyer has determined to be necessary in connection with the purchase of the Note; and (f) has had an opportunity to ask such questions and make such inquiries concerning the Company, its business, its financial condition and its prospects as the Buyer has deemed appropriate in connection with such purchase and to receive satisfactory answers to such questions and inquiries.

-2-

2.5No Conflicts; Advice. Neither the execution and delivery of this Agreement, nor the consummation of the transactions contemplated hereby, does or will violate any constitution, statute, regulation, rule, injunction, judgment, order, decree, ruling, charge or other restriction of any government, governmental agency, or court to which the Buyer is subject or any provision of its organizational documents or other similar governing instruments, or conflict with, violate or constitute a default under any agreement, credit facility, debt or other instrument or understanding to which the Buyer is a party. The Buyer has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Note.

2.6Non-Public Information. The Buyer is purchasing the Note “on the basis of” (as defined in Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) information provided in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and other publicly available financial information concerning the Company and such other disclosure regarding the Company, its business, its financial condition and its prospects as the Buyer has determined to be necessary in connection with the purchase of the Note, each of which documents are publicly available on the EDGAR database of the U.S. Securities and Exchange Commission (the “Commission”). The Buyer is not aware of and is not purchasing the Note “on the basis of” any material, non-public information about the Note or the Company.

2.7Compliance with Laws. To the extent applicable to the Buyer, the Buyer will comply with the requirements of U.S. federal and state law, and all applicable regulatory rules and procedures with respect to anti-money laundering obligations and know your customer obligations with respect to the Note, including, without limitation, applicable rules and regulation under the USA PATRIOT Act. Buyer hereby represents that neither it nor any of its owners or affiliates is a person or entity named on a list maintained by the Office of Foreign Asset Control (“OFAC”) of the U.S. Department of the Treasury, nor is the Buyer or any of its owners or affiliates a person or entity with whom dealings are prohibited under any OFAC regulations. Federal regulations and Executive Orders administered by OFAC prohibit, among other things, the engagement in transactions with, and the provision of services to, certain foreign countries, territories, entities and individuals. The lists of OFAC prohibited countries, territories, persons and entities, including, without limitation, the Specially Designated Nationals and Blocked Nations List, can be found on the OFAC website at http://www.ofac.treasury.gov. In addition, the programs administered by OFAC prohibit dealing with individuals or entities in certain countries regardless of whether such individuals or entities appear on the OFAC lists. Please be advised that the Company shall not be required to accept any amounts from Buyer if Buyer cannot make the representation set forth in the preceding sentence. The Buyer agrees to promptly notify the Company should the Buyer become aware of any change in the information set forth in these representations.

2.8Restricted Security. The Buyer understands that the Note has not been, and will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Buyer’s representations as expressed herein. The Buyer understands that the Note is a “restricted security” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Buyer must hold the Note indefinitely unless it is registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Buyer acknowledges that the Company has no obligation to register or qualify the Note for resale. The Buyer further acknowledges that if an

-3-

exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Note, and on requirements relating to the Company which are outside of the Buyer’s control, and which the Company is under no obligation to satisfyand may not be able to satisfy.

The Buyer understands that the Note may be notated with the following legend:

“THE NOTE REPRESENTED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND HAS BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN EXEMPTION FROM THE REGISTRATION REQUIREMENT APPLIES.”

3.3Private Offering by the Company. Neither the Company nor anyone acting on its behalf has offered the Note or any substantially similar debt security for sale to, or solicited any offer to buy the Note or any substantially similar debt securities from, or otherwise approached or negotiated in respect thereof with, any Person other than the Buyer and not more than 35 other non-accredited investors (as defined in the Securities Act), each of which has been offered the Note at a private sale for investment.

SECTION 6.Conditions to Closing.

6.1Conditions to Buyer’s Obligations. The obligations of the Buyer hereunder are subject to the accuracy, as of the date hereof and on the Closing Date, of the representations and warranties of the Company contained herein, except to the extent any such representation or warranty expressly specifies an earlier date, and to the performance by the Company of its obligations hereunder and to each of the following additional terms and conditions:

6.1.1Any authorizations, consents, commitments, agreements, orders or approvals of, or declarations or filings with, or expirations of waiting periods imposed by any federal, state or local court or governmental or regulatory agency or authority or applicable stock exchange or trading market (any such court, agency, authority, exchange or market, a “Governmental Authority”) required under applicable law for the consummation of the transactions contemplated hereby shall have been obtained or filed or shall have occurred and any such orders shall have become final, non-appealable orders. Each of the Company and Buyer agrees to use commercially reasonable efforts to take all actions, if any, and to do all things necessary, proper or advisable, if any, to obtain any applicable authorizations, consents, orders and approvals of all Governmental Authorities necessary for the Company to sell the Note on the Closing Date on terms consistent with the terms set forth in this Agreement.

6.2Conditions to the Company’s Obligations. The obligations of the Company hereunder are subject to the accuracy, as of the date hereof and as of the Closing Date, of the representations and warranties of Buyer contained herein and to the performance by the Buyer of its obligations hereunder and to the delivery by Buyer of the aggregate Purchase Price for the Note being purchased by Buyer, by wire transfer of immediately available funds pursuant to the wire instructions provided by the Company.

SECTION 7.Indemnification.

7.1Indemnified Parties. The Company shall indemnify, defend and hold harmless Buyer and Buyer’s affiliates and their respective directors, officers, employees, managers, partners, stockholders and agents (“Buyer Indemnified Parties”) from and against any and all losses, claims, damages, liabilities and expenses (“Claims”) based upon, arising out of or otherwise in respect of any material inaccuracy in, or any material breach of, the representations or warranties of the Company and the agreements made by the Company in this Agreement, except to the extent such loss, claim, damage, liability or expense is found to have resulted from such Buyer

-6-

Indemnified Party’s gross negligence, fraud, bad faith or willful misconduct. Buyer shall indemnify, defend and hold harmless the Company and Company’s affiliates and their respective directors, officers, employees, managers, partners, stockholders and agents (“Company Indemnified Parties” and together with the Buyer Indemnified Parties, each an “Indemnified Party”) from and against any and all Claims based upon, arising out of or otherwise in respect of any material inaccuracy in, or any material breach of, the representations or warranties of Buyer and the agreements made by Buyer in this Agreement, except to the extent such loss, claim, damage, liability or expense is found to have resulted from such Company Indemnified Party’s gross negligence, fraud, bad faith or willful misconduct.

7.2Process of Indemnification. The Indemnified Party agrees to advise the Indemnifying Party (defined below) of any Claim promptly after receipt of the notice thereof; provided, however, that the Indemnified Party’s right to indemnification hereunder shall not be limited by its failure to promptly advise the Indemnifying Party of any such claim or liability, except to the extent that the Indemnifying Party is prejudiced by such failure. The Indemnifying Party shall have the right, at its option, to assume the control of the Claim in respect of which indemnity may be sought hereunder, including the employment of counsel with respect thereto, in which event, except as provided below, the Indemnified Party shall not be liable for the fees and expenses of any other counsel retained by the Indemnified Party in connection with such Claim. In any such Claim of which the Indemnifying Party shall have so assumed, any Indemnified Party shall have the right to participate and to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless: (i) the Indemnifying Party and such Indemnified Party shall have mutually agreed in writing to the retention of such counsel; or (ii) the named parties to any such litigation or proceeding (including any impleaded parties) include the Indemnifying Party and one or more Indemnified Parties and such representation of both parties by the same counsel would, in the opinion of counsel to the Indemnified Party, be inappropriate due to actual legal conflict of interest. The Indemnifying Party agrees to keep the Indemnified Party informed of the status of any Claim hereunder. The Indemnifying Party will not, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld), settle any Claim relating to or arising out of this Agreement or any conduct hereunder unless such settlement: (i) includes an express, complete and unconditional release of the Indemnified Party with respect to all Claims asserted in or relating to this Agreement or any conduct hereunder, such release to be set forth in an instrument signed by all parties to such settlement; and (ii) does not include a statement as to or admission of, fault, culpability or a failure to act by the Indemnified Party. For purposes of this Agreement, “Indemnifying Person” shall mean the party providing indemnification. The provisions of this Section 7 shall survive the termination or expiration of this Agreement.
