*<u>Amendment to Credit Agreement, Amended and Restated Revolving Credit Note & Supplemental Revolving Credit Note</u>*

On December 29, 2022 (the "Amendment Date"), Pro-Dex, Inc. (the "Company") entered into Amendment No. 2 to Amended and Restated Credit Agreement (the "Amendment") with Minnesota Bank and Trust, a division of HTLF Bank ("MBT"), successor by merger to Minnesota Bank and Trust, which amends the Company's Amended and Restated Credit Agreement and Amended and Restated Revolving Credit Note with MBT (as amended, the "Credit Agreement" and "Revolving Note," respectively) and provides for a supplemental line of credit in the amount of $3,000,000 (the "Supplemental Note"). The Revolving Note has been amended to extend the maturity date of the Company's existing revolving credit note with MBT from November 5, 2023 to December 29, 2024, to increase the Revolving Note facility from $2,000,000 to $7,000,000, and to increase the interest rate on the Revolving Note (as described below). The Revolving Note may be borrowed against from time to time by the Company through its maturity date on the terms set forth in the Credit Agreement. As of the date of this Current Report on Form 8-K, the Company's has drawn $2,800,000 against the Revolving Note, the entire amount of which remains outstanding. Loan origination fees in the amount of $16,000 are payable to MBT in conjunction with the Revolving Note and Supplemental Note.

The Supplemental Note is evidenced by a Supplemental Revolving Credit Note dated as of the Amendment Date made by the Company in favor of MBT. The purpose of the Supplemental Note is for financing acquisitions and repurchasing shares of the Company's common stock. The Supplemental Note may be borrowed against from time to time by the Company through its maturity date of December 29, 2024 on the terms set forth in the Credit Agreement. No amounts have been drawn on the Supplemental Note as of the date of this Current Report on Form 8-K.

The Revolving Note and Supplemental Note bear interest at an annual rate equal to the greater of (a) 5.0% or (b) SOFR for a one-month period from the website of the CME Group Benchmark Administration Limited ("CBA") plus 2.5% (the "Adjusted Term SOFR Rate"). Commencing on the first day of each month after the Company initially borrows against the Revolving Note and/or Supplemental Note and each month thereafter until maturity, the Company is required to pay all accrued and unpaid interest on the Revolving Note and Supplemental Note through the date of payment. Any principal on the Revolving Note and/or Supplemental Note that is not previously prepaid by the Company shall be due and payable in full on the maturity date (or earlier termination of the Revolving Note and/or Supplemental Note).

Upon the occurrence and during the continuance of an event of default, the interest rate of the Revolving Note and Supplemental Note is increased by 3% and MBT may, at its option, declare the Revolving Note and Supplemental Note immediately due and payable in full.

The Credit Agreement, Revolving Note and Supplemental Note contain representations and warranties, affirmative, negative and financial covenants, and events of default that are customary for loans of this type.

Copies of the Amendment, Revolving Note and Supplemental Note are attached as exhibits to this Current Report on Form 8-K. The above descriptions are qualified by reference to the complete text of those documents. Copies of those documents are not intended to provide factual information about the Company. The representations, warranties, and covenants contained in those documents were made only for purposes of the transactions represented thereby as of the specific dates therein, are solely for the benefit of the Company and MBT, may be subject to limitations agreed upon by the Company and MBT, including, among others, being qualified by disclosures made for the purposes of allocating contractual risk between the parties instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under those documents and should not rely on the representations, warranties and covenants, or any descriptions thereof, as characterizations of the actual state of facts or condition of the Company. Moreover, information concerning the subject matter of representations and warranties contained in those documents may change after the date of those documents, which subsequent information may or may not be fully reflected in the Company's public disclosures. Rather, investors and the public should look to the disclosures contained in the Company's reports under the Securities Exchange Act of 1934, as amended, for information concerning the Company.

**FOR VALUE RECEIVED**, on the Revolving Credit Termination Date (as defined in the Credit Agreement hereinafter defined) the undersigned, **PRO-DEX, INC.**, a Colorado corporation (the "<u>Borrower</u>"), promises to pay to the order of **Minnesota Bank & Trust,** a division of HTLF Bank, successor by merger to Minnesota Bank and Trust (the "<u>Lender</u>"), the principal sum of SEVEN MILLION AND NO/100THS DOLLARS (U.S. $7,000,000.00) or, if less, the aggregate unpaid principal amount of all Revolving Credit Loans (as hereinafter defined) made by the Lender to the Borrower pursuant to the Credit Agreement.

**VARIABLE INTEREST RATE.** The interest rate on this Note is subject to change from time to time and interest shall accrue on the outstanding amounts under this Note at the following floating rate of interest per annum (the "Index"): an adjusted rate (the "Adjusted Term SOFR Rate") that is equal to: (1) the greater of (A) five percent (5.0%) (the "Floor") and (B) the forward-looking term rate based on SOFR for a one month period (to the extent that such tenor is available to Lender and Lender has determined it can be administered), as quoted by Lender based on the website of the CME Group Benchmark Administration Limited (CBA) (or a successor administrator of the Term SOFR Rate selected by Lender (the "Term SOFR Administrator"))("Term SOFR"), based on the applicable Term SOFR rate as determined by Lender and as in effect on each applicable date of determination, in each case, as such Term SOFR rate changes and is recalculated from time to time in accordance with the terms below, and as adjusted for all applicable reserve requirements and any costs arising from time to time in connection with a change in government regulation as reasonably determined by Lender (such higher amount, the "Term SOFR Rate"), plus (2) two and one half percent (2.5%) (the "Term SOFR Margin"); provided, that in the event Borrower enters into an interest swap with Lender with respect to interest accruing under this Note, the Floor will automatically be deemed not to apply to the principal portion of this Note that is so hedged for the duration of such interest rate swap transaction and the foregoing is limited solely to an interest rate swap transaction with the Lender and shall not apply to any other derivative product, such as in interest rate cap or collar.

Interest accrued during each calendar month shall be due and payable on the first day of the following calendar month, with the first such interest payment due on January 1, 2023.

Subject to the terms of this Note, so long as the amounts outstanding under this Note are accruing interest at the Adjusted Term SOFR Rate, then the Term SOFR Rate will be reset on each Business Day (the "Reset Date") using the Term SOFR Rate as determined two U.S. Government Securities Business Days preceding the applicable Reset Date (the "Daily Reference Date"); provided, that in the event Borrower enters into an interest rate hedge, swap, collar or other similar derivative transaction with Lender with respect to interest accruing under this Note, the Term SOFR Rate will be reset on the first (1st) day or the fifteenth (15th) day of each month, as applicable, using the Term SOFR Rate as determined two U.S. Government Securities Business Days preceding such applicable day of the month (the "Monthly Reference Date"); provided, further, that if Term SOFR for a one month interest period is not published for any applicable Daily Reference Date or Monthly Reference Date, and Lender determines in its sole discretion that such failure is temporary, the applicable Term SOFR Rate shall be the Term SOFR Rate for a one month period as published on the most recent applicable Business Day that Lender determines such Term SOFR Rate was available prior to the applicable Daily Reference Date or Monthly Reference Date. The term "Business Day" means any day that is not a Saturday, Sunday or other day that is a legal holiday under the laws of the State of New York or is a day on which banking institutions in such state are authorized or required by law to close. The term "U.S. Government Securities Business Day" means any day except for a Saturday, a Sunday or 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 U.S. Government Securities. The term "Federal Reserve Board" means the Board of Governors of the Federal Reserve System of the United States. The term "SOFR" means a rate equal to the secured overnight financing rate as administered by the SOFR Administrator.

**FOR REFERENCE ONLY**, on the date hereof, the Term SOFR Rate is 4.32304% per annum and the Adjusted Term SOFR Rate is 4.32304%. The Term SOFR Rate is an index used by Lender for the determination of interest and Term SOFR Rate and the Adjusted Term SOFR Rate are not necessarily the lowest interest rates charged by Lender on other loans to other customers. Borrower understands and agrees that Lender may make loans to other customers based on other rates of interest as well. Lender will inform Borrower of the current Adjusted Term SOFR Rate from time to time upon request by Borrower.

**INTEREST CALCULATION METHOD.** Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the applicable 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. This calculation method results in a higher effective interest rate than the numeric interest rate stated in this Note. The Term SOFR Rate shall be determined by Lender in accordance with the terms hereof, and such determination shall be conclusive absent manifest error.

**CONFORMING CHANGES ADJUSTMENT.** In connection with the use or administration of Term SOFR, the Term SOFR Rate and Adjusted Term SOFR Rate, Lender will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary in this Note or in any other promissory notes, loan documents or security documents, or other agreements between Borrower and Lender (each a "Loan Document"), and any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Note or any other Loan Document. Lender will notify Borrower from time to time of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR, the Term SOFR Rate or Adjusted Term SOFR Rate. The term "Conforming Changes" means, with respect to either the use or administration of Term SOFR, the Term SOFR Rate or the Adjusted Term SOFR Rate or the use, administration, adoption or implementation of any Benchmark (as defined below) replacement, any technical, administrative or operational changes (including changes to the definition of "Business Day"), timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, the applicability and length of lookback periods, and other technical, administrative or operational matters) that Lender decides may be appropriate to reflect the adoption and implementation of any such rate or to permit the use and administration thereof by Lender in a manner substantially consistent with market practice (or, if Lender decides that adoption of any portion of such market practice is not administratively feasible or if Lender determines that no market practice for the administration of any such rate exists, in such other manner of administration as Lender decides is reasonably necessary in connection with the administration of this Note and the other Loan Documents).

**UNAVAILABILITY OF SOFR/BENCHMARK REPLACEMENT.** Subject to the Benchmark Replacement provisions below, if, in connection with the implementation and use of the Term SOFR Rate: (a) Lender determines (which determination shall be conclusive and binding absent manifest error) that the "Term SOFR Rate" cannot be determined pursuant to the definition thereof, (b) Lender reasonably determines that the Adjusted Term SOFR Rate does not adequately and fairly reflect the cost to Lender, or (c) Lender determines that any applicable law has made it unlawful, or that any governmental authority has asserted that it is unlawful, for Lender or its applicable lending office to make, maintain or fund loans or advances whose interest is determined by reference to SOFR, Term SOFR, or the Term SOFR Rate, or to determine or charge interest rates based upon SOFR, Term SOFR, or the Term SOFR Rate; then upon notice of any such occurrence or determination by Lender to Borrower, any obligation of Lender to make available the Adjusted Term SOFR Rate, and any right of Borrower to use the Adjusted Term SOFR Rate, shall be suspended until Lender revokes such notice. Upon receipt of such notice, all amounts outstanding under this Note will be deemed to accrue at the Benchmark Replacement rate, if applicable, or if such Benchmark Replacement rate is not available or does not adequately and

fairly reflect the cost to Lender, at the Adjusted Prime Rate. The term "Adjusted Prime Rate" means a variable rate of interest that is equal to: (1) the greater of (A) five percent (5.0%), and (B) the rate last quoted by The Wall Street Journal as the "Prime Rate" in the United States or, if The Wall Street Journal ceases to quote such rate, the highest per annum interest rate published by the Federal Reserve Board in Federal Reserve Statistical Release H.15 (519) (Selected Interest Rates) as the "bank prime loan" rate or, if such rate is no longer quoted therein, any similar rate quoted therein (as determined by Lender) or any similar release by the Federal Reserve Board (as determined by Lender) (such higher amount, the "Prime Rate"), plus (2) an applicable percentage selected by Lender, taking into consideration any selection or recommendation of a replacement rate by any relevant agency or authority, and evolving or prevailing market practice, to reasonably approximate the Adjusted Term SOFR Rate or otherwise adequately and fairly reflect the cost to Lender, as determined in its discretion (the "Prime Margin").

**BENCHMARK REPLACEMENT.** 

(a)Benchmark Replacement. Notwithstanding anything to the contrary, if Lender has determined in its sole discretion that (i) the administrator of Term SOFR, or any relevant agency or authority for such administrator, of Term SOFR (or any substitute index which replaces the Term SOFR (Term SOFR or such replacement, the "Benchmark")) has announced that such Benchmark will no longer be provided, (ii) any relevant agency or authority has announced that such Benchmark is no longer representative, or (iii) any similar circumstance exists such that such Benchmark has become permanently unavailable or ceased to exist (each a "Benchmark Transition Event"), then Lender shall (x) replace such Benchmark with a replacement rate or (y) if one or more such circumstances apply to fewer than all tenors of such Benchmark used for determining an Interest Period hereunder, discontinue the availability of the affected interest periods. With respect to Term SOFR, such replacement rate will be Daily Simple SOFR unless Lender reasonably determines that Daily Simple SOFR is not readily available or shall otherwise reasonably determine that a different rate has been recommended as a replacement benchmark rate for determining such a rate by the by the Federal Reserve Board or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board or the Federal Reserve Bank of New York, or any successor thereto (the "Relevant Governmental Body"). In the case of a replacement rate other than Term SOFR, Lender may add a spread adjustment selected by Lender, taking into consideration any selection or recommendation of a replacement rate by any relevant agency or authority, and evolving or prevailing market practice. Such replacement rates for the Benchmark as applicable, each a "Benchmark Replacement". The term "Daily Simple SOFR" means a daily rate based on SOFR and determined by Lender in accordance with the conventions for such rate selected by Lender.

(b)Notices; Standards for Decisions and Determinations. Lender will notify Borrower of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. Lender will notify Borrower of the removal or reinstatement of any tenor of a Benchmark pursuant to clause (a) above. Any determination, decision or election that may be made by Lender pursuant to this provision, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its sole discretion and without consent from any other party to this Note or any other Loan Documents, except, in each case, as expressly required pursuant to this provision.

**Payments**. Both principal and interest are payable in lawful money of the United States of America to the Lender at 9800 Bren Road East, Suite 200, Minnetonka, MN 55343 (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.

**Prepayment; Minimum Interest Charge**. In any event, even upon full prepayment of this Note, Borrower understands that Lender is entitled to a minimum interest charge of $15.00. Other than Borrower's obligations to pay any minimum interest charge, Borrower may pay without penalty all or a portion of the amount earlier than it is due. 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, 9800 Bren Road East, Suite 200, Minnetonka, MN 55343.

**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.

**FOR VALUE RECEIVED**, on the Supplemental Revolving Credit Termination Date (as defined in the Credit Agreement hereinafter defined) the undersigned, **PRO-DEX, INC.**, a Colorado corporation (the "<u>Borrower</u>"), promises to pay to the order of **Minnesota Bank & Trust,** a division of HTLF Bank, successor by merger to Minnesota Bank and Trust (the "<u>Lender</u>"), the principal sum of THREE MILLION AND NO/100THS DOLLARS (U.S. $3,000,000.00) or, if less, the aggregate unpaid principal amount of all Supplemental Revolving Credit Loans (as hereinafter defined) made by the Lender to the Borrower pursuant to the Credit Agreement.

**VARIABLE INTEREST RATE.** The interest rate on this Note is subject to change from time to time and interest shall accrue on the outstanding amounts under this Note at the following floating rate of interest per annum (the "Index"): an adjusted rate (the "Adjusted Term SOFR Rate") that is equal to: (1) the greater of (A) five percent (5.0%) (the "Floor") and (B) the forward-looking term rate based on SOFR for a one month period (to the extent that such tenor is available to Lender and Lender has determined it can be administered), as quoted by Lender based on the website of the CME Group Benchmark Administration Limited (CBA) (or a successor administrator of the Term SOFR Rate selected by Lender (the "Term SOFR Administrator"))("Term SOFR"), based on the applicable Term SOFR rate as determined by Lender and as in effect on each applicable date of determination, in each case, as such Term SOFR rate changes and is recalculated from time to time in accordance with the terms below, and as adjusted for all applicable reserve requirements and any costs arising from time to time in connection with a change in government regulation as reasonably determined by Lender (such higher amount, the "Term SOFR Rate"), plus (2) two and one half percent (2.5%) (the "Term SOFR Margin"); provided, that in the event Borrower enters into an interest swap with Lender with respect to interest accruing under this Note, the Floor will automatically be deemed not to apply to the principal portion of this Note that is so hedged for the duration of such interest rate swap transaction and the foregoing is limited solely to an interest rate swap transaction with the Lender and shall not apply to any other derivative product, such as in interest rate cap or collar.

Interest accrued during each calendar month shall be due and payable on the first day of the following calendar month, with the first such interest payment due on January 1, 2023.

Subject to the terms of this Note, so long as the amounts outstanding under this Note are accruing interest at the Adjusted Term SOFR Rate, then the Term SOFR Rate will be reset on each Business Day (the "Reset Date") using the Term SOFR Rate as determined two U.S. Government Securities Business Days preceding the applicable Reset Date (the "Daily Reference Date"); provided, that in the event Borrower enters into an interest rate hedge, swap, collar or other similar derivative transaction with Lender with respect to interest accruing under this Note, the Term SOFR Rate will be reset on the first (1st) day or the fifteenth (15th) day of each month, as applicable, using the Term SOFR Rate as determined two U.S. Government Securities Business Days preceding such applicable day of the month (the "Monthly Reference Date"); provided, further, that if Term SOFR for a one month interest period is not published for any applicable Daily Reference Date or Monthly Reference Date, and Lender determines in its sole discretion that such failure is temporary, the applicable Term SOFR Rate shall be the Term SOFR Rate for a one month period as published on the most recent applicable Business Day that Lender determines such Term SOFR Rate was available prior to the applicable Daily Reference Date or Monthly Reference Date. The term "Business Day" means any day that is not a Saturday, Sunday or other day that is a legal holiday under the laws of the State of New York or is a day on which banking institutions in such state are authorized or required by law to close. The term "U.S. Government Securities Business Day" means any day except for a Saturday, a Sunday or 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 U.S. Government Securities. The term "Federal Reserve Board" means the Board of Governors of the Federal Reserve System of the United States. The term "SOFR" means a rate equal to the secured overnight financing rate as administered by the SOFR Administrator.

**FOR REFERENCE ONLY**, on the date hereof, the Term SOFR Rate is 4.32304% per annum and the Adjusted Term SOFR Rate is 4.32304%. The Term SOFR Rate is an index used by Lender for the determination of interest and Term SOFR Rate and the Adjusted Term SOFR Rate are not necessarily the lowest interest rates charged by Lender on other loans to other customers. Borrower understands and agrees that Lender may make loans to other customers based on other rates of interest as well. Lender will inform Borrower of the current Adjusted Term SOFR Rate from time to time upon request by Borrower.

**INTEREST CALCULATION METHOD.** Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the applicable 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. This calculation method results in a higher effective interest rate than the numeric interest rate stated in this Note. The Term SOFR Rate shall be determined by Lender in accordance with the terms hereof, and such determination shall be conclusive absent manifest error.

**CONFORMING CHANGES ADJUSTMENT.** In connection with the use or administration of Term SOFR, the Term SOFR Rate and Adjusted Term SOFR Rate, Lender will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary in this Note or in any other promissory notes, loan documents or security documents, or other agreements between Borrower and Lender (each a "Loan Document"), and any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Note or any other Loan Document. Lender will notify Borrower from time to time of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR, the Term SOFR Rate or Adjusted Term SOFR Rate. The term "Conforming Changes" means, with respect to either the use or administration of Term SOFR, the Term SOFR Rate or the Adjusted Term SOFR Rate or the use, administration, adoption or implementation of any Benchmark (as defined below) replacement, any technical, administrative or operational changes (including changes to the definition of "Business Day"), timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, the applicability and length of lookback periods, and other technical, administrative or operational matters) that Lender decides may be appropriate to reflect the adoption and implementation of any such rate or to permit the use and administration thereof by Lender in a manner substantially consistent with market practice (or, if Lender decides that adoption of any portion of such market practice is not administratively feasible or if Lender determines that no market practice for the administration of any such rate exists, in such other manner of administration as Lender decides is reasonably necessary in connection with the administration of this Note and the other Loan Documents).

**UNAVAILABILITY OF SOFR/BENCHMARK REPLACEMENT.** Subject to the Benchmark Replacement provisions below, if, in connection with the implementation and use of the Term SOFR Rate: (a) Lender determines (which determination shall be conclusive and binding absent manifest error) that the "Term SOFR Rate" cannot be determined pursuant to the definition thereof, (b) Lender reasonably determines that the Adjusted Term SOFR Rate does not adequately and fairly reflect the cost to Lender, or (c) Lender determines that any applicable law has made it unlawful, or that any governmental authority has asserted that it is unlawful, for Lender or its applicable lending office to make, maintain or fund loans or advances whose interest is determined by reference to SOFR, Term SOFR, or the Term SOFR Rate, or to determine or charge interest rates based upon SOFR, Term SOFR, or the Term SOFR Rate; then upon notice of any such occurrence or determination by Lender to Borrower, any obligation of Lender to make available the Adjusted Term SOFR Rate, and any right of Borrower to use the Adjusted Term SOFR Rate, shall be suspended until Lender revokes such notice. Upon receipt of such notice, all amounts outstanding under this Note will be deemed to accrue at the Benchmark Replacement rate, if applicable, or if such Benchmark Replacement rate is not available or does not adequately and

fairly reflect the cost to Lender, at the Adjusted Prime Rate. The term "Adjusted Prime Rate" means a variable rate of interest that is equal to: (1) the greater of (A) five percent (5.0%), and (B) the rate last quoted by The Wall Street Journal as the "Prime Rate" in the United States or, if The Wall Street Journal ceases to quote such rate, the highest per annum interest rate published by the Federal Reserve Board in Federal Reserve Statistical Release H.15 (519) (Selected Interest Rates) as the "bank prime loan" rate or, if such rate is no longer quoted therein, any similar rate quoted therein (as determined by Lender) or any similar release by the Federal Reserve Board (as determined by Lender) (such higher amount, the "Prime Rate"), plus (2) an applicable percentage selected by Lender, taking into consideration any selection or recommendation of a replacement rate by any relevant agency or authority, and evolving or prevailing market practice, to reasonably approximate the Adjusted Term SOFR Rate or otherwise adequately and fairly reflect the cost to Lender, as determined in its discretion (the "Prime Margin").

**BENCHMARK REPLACEMENT.** 

(a)Benchmark Replacement. Notwithstanding anything to the contrary, if Lender has determined in its sole discretion that (i) the administrator of Term SOFR, or any relevant agency or authority for such administrator, of Term SOFR (or any substitute index which replaces the Term SOFR (Term SOFR or such replacement, the "Benchmark")) has announced that such Benchmark will no longer be provided, (ii) any relevant agency or authority has announced that such Benchmark is no longer representative, or (iii) any similar circumstance exists such that such Benchmark has become permanently unavailable or ceased to exist (each a "Benchmark Transition Event"), then Lender shall (x) replace such Benchmark with a replacement rate or (y) if one or more such circumstances apply to fewer than all tenors of such Benchmark used for determining an Interest Period hereunder, discontinue the availability of the affected interest periods. With respect to Term SOFR, such replacement rate will be Daily Simple SOFR unless Lender reasonably determines that Daily Simple SOFR is not readily available or shall otherwise reasonably determine that a different rate has been recommended as a replacement benchmark rate for determining such a rate by the by the Federal Reserve Board or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board or the Federal Reserve Bank of New York, or any successor thereto (the "Relevant Governmental Body"). In the case of a replacement rate other than Term SOFR, Lender may add a spread adjustment selected by Lender, taking into consideration any selection or recommendation of a replacement rate by any relevant agency or authority, and evolving or prevailing market practice. Such replacement rates for the Benchmark as applicable, each a "Benchmark Replacement". The term "Daily Simple SOFR" means a daily rate based on SOFR and determined by Lender in accordance with the conventions for such rate selected by Lender.

(b)Notices; Standards for Decisions and Determinations. Lender will notify Borrower of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. Lender will notify Borrower of the removal or reinstatement of any tenor of a Benchmark pursuant to clause (a) above. Any determination, decision or election that may be made by Lender pursuant to this provision, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its sole discretion and without consent from any other party to this Note or any other Loan Documents, except, in each case, as expressly required pursuant to this provision.

**Payments**. Both principal and interest are payable in lawful money of the United States of America to the Lender at 9800 Bren Road East, Suite 200, Minnetonka, MN 55343 (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.

**Prepayment; Minimum Interest Charge**. In any event, even upon full prepayment of this Note, Borrower understands that Lender is entitled to a minimum interest charge of $15.00. Other than Borrower's obligations to pay any minimum interest charge, Borrower may pay without penalty all or a portion of the amount earlier than it is due. 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, 9800 Bren Road East, Suite 200, Minnetonka, MN 55343.

**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.
