TERM NOTE C Page 2 U.S. $1,050,000.00 Dated as of May 15, 2025 Eagan, Minnesota Government Securities Business Day prior to the Reset Date (the “Index”). The Index is not necessarily the lowest rate charged by Lender on its loans. Lender will tell Borrowing Agent the current index rate upon Borrowing Agent’s request. The interest rate change will not occur more often than each month. For purposes of this Note, “U.S. Government Securities Business Day” means any day except for (i) a Saturday, (ii) a Sunday or (iii) a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in United States government securities. (c) Rate Change Effective Date. Each change in interest rate shall be effective on the 15th day of each month commencing on June 15, 2025 (the “Reset Date”). (d) Regulatory Change; etc. Interest on the unpaid principal balance of this Note will be calculated as described in the “INTEREST CALCULATION METHOD” paragraph. Notwithstanding anything herein to the contrary, if the Lender determines in good faith (which determination shall be conclusive, absent manifest error) that: (A) adequate and fair means do not exist for ascertaining CME one-month term SOFR, (B) CME one-month term SOFR does not accurately reflect the cost to the Lender of the Loan, or (C) a Regulatory Change (as hereinafter defined) shall, in the reasonable determination of the Lender, make it unlawful or commercially unreasonable for the Lender to use CME one-month term SOFR as the index for purposes of determining the interest rate, then: (i) CME one-month term SOFR shall be replaced with an alternative or successor rate or index chosen by the Lender in its reasonable discretion; and (ii) the Applicable Margin may also be adjusted by Lender in its reasonable discretion, giving due consideration to market convention for determining rates of interest on comparable loans. “Regulatory Change” shall mean a change in any applicable law, treaty, rule, regulation or guideline, or the interpretation or administration thereof, by the administrator of the relevant benchmark or its regulatory supervisor, any governmental authority, central bank or other fiscal, monetary, or other authority having jurisdiction over Lender or its lending office. Such an amendment to the terms of this Note will become effective and bind Borrowers 10 Business Days after Lender gives written notice to Borrowing Agent without any action or consent of the Borrowers. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law. If any payment hereunder becomes due and payable on a day other than a Business Day, such payment shall be effective the next succeeding Business Day, provided, however, payments scheduled to be made automatically from an Alerus Financial, National Association deposit account on the date the payment is due will be applied in reduction of the Note balance effective as of the scheduled payment date. (e) Upon the occurrence of an Event of Default, including failure to pay upon final maturity, the interest rate on this Note shall be increased by adding an additional 5.000 percentage point margin (such increased rate of interest being, the “Default Rate”). However, in no event will the interest rate exceed the maximum interest rate limitations

Both principal and interest are payable in lawful money of the United States of America to the Lender at Alerus Financial, National Association, 2805 Dodd Rd., Suite 160, Eagan, MN 55121 (or other location specified by the Lender) in immediately available funds. Borrowers shall jointly and severally pay the principal of this Note and interest thereon as follows: i. on the fifteenth day of each month, commencing June 15, 2025, there shall be due and Borrowers shall jointly and severally make monthly payments of principal, each in the amount of $12,500.00, plus accrued interest; and ii. the Loan shall be due and payable in full, and Borrowers hereby jointly and severally promise to pay the outstanding principal amount of the Loan to Lender, together with all accrued interest thereon then remaining unpaid and all other unpaid amounts, charges, fees and expenses outstanding under this Note or under any of the other Loan Documents, on the Maturity Date, subject to earlier prepayment as provided herein or in any other Loan Document. (b) Method of Payments. By its execution of this Note, each Borrower authorizes the Lender to charge from time to time against any of such Borrower’s depository accounts maintained with the Lender any such payments when due and the Lender will use its reasonable efforts to notify the Borrowing Agent of such charges. (c) Application of Payments. At Lender’s option, any payment or prepayment under this Note may be applied first to the payment of charges, fees and expenses (other than principal and interest) under this Note and any other agreement or writing in connection with this Note, second to the payment of interest accrued to the date of payment, and third to the payments of scheduled principal under this Note in inverse order of maturity. Also, at Lender’s option, if there is any overpayment of interest under this Note, Lender may hold the excess and apply it to future interest accruing under this Note. No prepayment shall suspend any required payments of either principal or interest or reduce the amount of any scheduled payment. 3. Interest Calculation Method. Interest on this Note is computed on a 365/360 basis; that is by applying the ratio of the Interest Rate over a year of 360 days multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method. If any payment to be made by the Borrowers hereunder shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day (without the obligation to pay the additional days of accrued interest).

TERM NOTE C Page 4 U.S. $1,050,000.00 Dated as of May 15, 2025 Eagan, Minnesota 4. Prepayment; Minimum Interest Charge. This Note may be prepaid in whole or in part at any time; provided, that any such prepayment is accompanied by accrued interest on the amount being prepaid through the date of prepayment. In any event, even upon full prepayment of this Note, Borrowers understand that Lender is entitled to a minimum interest charge of $10.00. Early payments will not, unless agreed to by Lender in writing, relieve Borrowers of Borrowers’ obligation to continue to make payments of accrued unpaid interest. Rather, early payment will reduce the principal balance due. Borrowers agree not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrowers send such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrowers will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: Alerus Financial, National Association, 2805 Dodd Rd., Suite 160, Eagan, MN 55121. 5. Late Charge. If a payment due hereunder is not made within ten days after the date when due, Borrowers shall pay to Lender a late payment charge of 5% of the amount of the overdue payment to compensate Lender for a portion of the cost related to handling the overdue payment. 6.

This Note shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns except that no Borrower may assign or transfer their rights hereunder without the prior written consent of Lender, which consent may be withheld in Lender’s sole discretion. 12.
