This Note is made pursuant to the terms and conditions set forth in that certain Loan Agreement dated of even date herewith by and between Borrower and Lender (as amended, modified, supplemented or restated from time to time being the “Loan Agreement”). The amount disbursed by the Lender to Borrower, repayment of which is evidenced by this Note, is referred to as the “Loan”. All capitalized terms used and not expressly defined herein shall have the meanings given to such terms in the Loan Agreement. 1. Interest. (a) Interest Rate. The Borrower promises to pay interest (computed on the basis of the number of days elapsed in a year of 360 days) on the unpaid principal amount hereof from the date hereof until such principal amount is paid in full at a fluctuating annual rate of interest equal to the sum of the greater of: (i) 5.00% or (ii) the sum of (A) 1.90% (the “Applicable Margin”) plus (B) the Index (hereinafter defined), as in effect on the date hereof and as the same may adjust from time to time. (b) Variable Interest Rate. The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the CME one-month term SOFR published by CME Group Benchmarks Administration Limited (or a successive administrator designated by the relevant authority) for the date that is two U.S. Government Securities Business Days prior to the Reset Date (the “Index”). The Index is not necessarily the lowest rate charged by Lender on its loans. Lender will tell Borrower the current index rate upon Borrower’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.

TERM NOTE Page 2 U.S. $6,000,000.00 Dated as of November 24, 2025 Eagan, Minnesota (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 Borrower 10 Business Days after Lender gives written notice to Borrower without any action or consent of the Borrower. 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 under applicable law. 2. Payment Terms. (a) Payment Dates. 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.

TERM NOTE Page 3 U.S. $6,000,000.00 Dated as of November 24, 2025 Eagan, Minnesota principal on this Note, each in the amount of $857,142.86, on September 30 of each year, commencing September, 2026. ii. The Loan shall be due and payable in full, and Borrower hereby promises 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, the 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 Borrower 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 Borrower 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). 4. Prepayment; Minimum Interest Charge. This Note may be prepaid in whole or in part at any time; provided, however, 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, Borrower understands that Lender is entitled to a minimum interest charge of $10.00. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments of accrued unpaid interest. Rather, early payment will reduce the principal balance due. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed

TERM NOTE Page 4 U.S. $6,000,000.00 Dated as of November 24, 2025 Eagan, Minnesota 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. Ste 160, Eagan, MN 55121. Prepayment of the principal amount of the Note, in whole or in part, whether voluntary or involuntary, will be subject to payment by Borrower to Lender of all assessments, losses, fees and costs of any kind or nature incurred by Lender under any and all Swap Transaction Documents by and between Borrower and Lender, which arise, directly or indirectly, as a result of such prepayment. Moreover, at no time during the term of the Loan may the then principal balance of the Loan be less than the then remaining notional amount of the Swap, and any prepayment of the Note below the notional amount will require an equivalent reduction in the notional amount under the Swap Transaction Documents. This prepayment penalty provision is only applicable if the Borrower and Lender have entered into a Swap Transaction evidenced by a separate Swap Transaction Document. 5. Late Charge. If a payment due hereunder is not made within ten days after the date when due, Borrower 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.

Any Event of Default (as defined in the Loan Agreement) shall constitute an Event of Default under this Note.
