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 Credit Agreement.

Interest Prior to Default.

(a)

Interest Rate. The Borrower promises to pay interest on the unpaid principal amount hereof from the date hereof until such principal amount is paid in full at a per annum rate of interest (the “Interest Rate”) of 3.84%.

(b)

Change in Capital Adequacy Requirements. Section 3.02 of the Credit Agreement is hereby incorporated herein in its entirety.

(c)

Interest After Default. Upon the occurrence and during the continuance 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 3.000 percentage point margin (“Default Rate Margin”) over the interest rate that would otherwise be in effect hereunder. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.

Payment Terms.

(a)

Principal and Interest. Payments of principal and interest due under this Note, if not sooner declared to be due in accordance with the provisions hereof, shall be made as follows (each such date when a payment is due and payable, a “Payment Date”):

(i)

On the first day of each month, commencing December 1, 2020 through and including June 1, 2021, the Borrower shall make a payment of accrued interest;

Page 2

(ii)

On the first day of each subsequent month and continuing until the Maturity Date, the Borrower shall make equal payments of principal and interest, each in the amount necessary to fully amortize the outstanding principal balance hereunder on June 1, 2021 over the remaining term of this Note (e.g., if the outstanding principal balance on June 1, 2021 is $7,525,000, the amount of each such payment will be $109,168.18); and

(iii)

The Loan shall be due and payable, 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.

(b)

Method of Payments. Both principal and interest are payable in lawful money of the United States of America to the Lender at 7701 France Avenue South, Edina, MN 55435 (or other location specified by the Lender) in immediately available funds. By its execution of this Note, the Borrower authorizes the Lender to charge from time to time against any of 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.

Interest Calculation Method. Interest on this Note shall be calculated on the basis of a 360-day year and the actual number of days elapsed in any portion of a month in which interest is due. 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.

Prepayment; Minimum Interest Charge. Borrower may voluntarily prepay the loan evidenced by this Note in whole or in part at any time; provided, however, that any such prepayment shall be accompanied by a prepayment premium in immediately available funds (the “Prepayment Premium”) equal to: (1) 4% of the amount prepaid if such event occurs during the first Loan Year; (2) 3% of the amount prepaid if such event occurs during the second Loan Year; (3) 2% of the amount prepaid if such event occurs during the third Loan Year; or (4) 1% of the amount prepaid if such event occurs during the fourth or fifth Loan Year. After the expiration of the fifth Loan Year, the Borrower shall have no obligation to pay any Prepayment Premium on any prepayments under this Note. For purposes of this Note, the term “Loan Year” shall mean the 12-month period commencing on the date of this Note (or the anniversary date thereof in any subsequent year) and ending on the day preceding the immediately following anniversary date of this Note (i.e., the first Loan Year shall end on November 5, 2021 and the second Loan Year shall commence on November 6, 2022). Notwithstanding the foregoing, no Prepayment Premium shall be due on prepayments in an aggregate amount of up to twenty percent (20%) of outstanding principal of the Loan in any Loan Year if such prepayment is made from the Borrower’s internally-generated cash flow.   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 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: Minnesota Bank & Trust, 7701 France Avenue South, Edina, MN 55435.

Late Charge. If a payment due hereunder is not made within seven 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.

Credit Agreement. This Note is the Term Note A referred to in, and is entitled to the benefits of, the Credit Agreement. The Credit Agreement, among other things, (i) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events prior to the maturity hereof upon the terms and conditions therein specified; (ii) contains provisions for the mandatory prepayment hereof upon certain conditions; and (iii) contains provisions for the voluntary prepayment hereof, upon certain conditions.

No extension of time for the payment of this Note, or any installment thereof, made by agreement by Lender with any person now or hereafter liable for the payment of this Note, shall affect the original liability under this Note of the undersigned, even if the undersigned is not a party to such agreement.

Event of Default. Any Event of Default (as defined in the Credit Agreement) shall constitute an Event of Default under this Note. Upon the occurrence of an Event of Default, in addition to any other rights or remedies Lender may have at law or in equity or under the Credit Agreement or under any other Loan Document, Lender may, at its option, without notice to Borrower, declare immediately due and payable the entire unpaid principal sum hereof, together with all accrued and unpaid interest thereon plus any other sums owing at the time of such Event of Default pursuant to this Note, the Security Agreement or any other Loan Document.  The failure to exercise the

foregoing or any other options shall not constitute a waiver of the right to exercise the same or any other option at any subsequent time in respect of the same event or any other event. The acceptance by the holder of any payment hereunder which is less than payment in full of all amounts due and payable at the time of such payment shall not constitute a waiver of the right to exercise any of the foregoing options at that time or at any subsequent time.

Expense Reimbursement. Borrower agrees to reimburse Lender upon demand for all reasonable out-of-pocket expenses (including attorneys’ fees and legal expenses) in connection with Lender’s enforcement of the obligations of the Borrower hereunder or under the Security Agreement or any other collateral document, whether or not suit is commenced including, without limitation, attorneys’ fees and legal expenses in connection with any appeal of a lower court’s order or judgment. The obligations of the Borrower under this paragraph shall survive any termination of the Credit Agreement, this Note, the Security Agreement, and any other Loan Document.

Usury.
