or household use) and is or will be evidenced by a promissory note or notes of the Borrower and all renewals, extensions, amendments and
restatements thereof (whether one or more, collectively, the “Note”) acceptable to the Bank, which shall set forth
the interest rate, repayment and other provisions of the respective Loan, the terms of which are incorporated into this Agreement by reference.

 

The Loans governed by this Agreement shall include the Loans specifically
described below, if any, and any additional lines of credit or term loans that the Bank has made or may, in its sole discretion, make

Security. The security for repayment
of the Loan shall include but not be limited to the collateral, guaranties and other documents heretofore, contemporaneously or hereafter

loans, advances, debts, liabilities, obligations, covenants and duties owing by the Borrower to the Bank described therein (hereinafter
referred to collectively as the “Obligations”).

 

This Agreement, the Note, the Security Documents and all other agreements
and documents executed and/or delivered pursuant or subject hereto, as each may be amended, modified, extended or renewed from time to

suit, proceeding or investigation which could result in such a material adverse change. All pending and threatened litigation against
the Borrower is listed on the Addendum attached hereto.

to terminate any such plan.

 

3.10

proceeding arising under, relating to or in connection with any Environmental Law is pending or, to the best of the Borrower’s knowledge,
threatened against the Borrower, any real property in which the Borrower holds or has held an interest or any past or present operation
of the Borrower. No release, threatened release or disposal of hazardous waste, solid waste or other wastes is occurring, or to the best
of the Borrower’s knowledge has occurred, on, under or to any real property in which the Borrower holds or has held any interest
or performs or has performed any of its operations, in violation of any Environmental Law. As used in this Section, “litigation
or proceeding” means any demand, claim notice, suit, suit in equity, action, administrative action, investigation or inquiry
whether brought by a governmental authority or other person, and “Environmental Laws” means all provisions of laws,
statutes, ordinances, rules, regulations, permits, licenses, judgments, writs, injunctions, decrees, orders, awards and standards promulgated

3.12         
Regulatory Matters. No part of the proceeds of any Loan will be used for “purchasing”
or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U

3.14         
Disclosure. None of the Loan Documents contains or will contain any untrue statement of
material fact or omits or will omit to state a material fact necessary in order to make the statements contained in this Agreement or
the Loan Documents not misleading. There is no fact known to the Borrower which materially adversely affects or, so far as the Borrower
can now foresee, might materially adversely affect the business, assets, operations, condition (financial or otherwise) or results of
operation of the Borrower and which has not otherwise been fully set forth in this Agreement or in the Loan Documents.

FOR VALUE RECEIVED, NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION
(the “Borrower”), with an address at 4201 WOODLAND ROAD, CIRCLE PINES, MINNESOTA 55014-1794, promises to pay to
the order of PNC BANK, NATIONAL ASSOCIATION (the “Bank”), in lawful money of the United States of America in
immediately available funds at its offices located at 1900 E 9th St, Cleveland, Ohio 44114, or at such other location as the Bank may
designate from time to time, the principal sum of $5,000,000.00 (the “Facility”) or such lesser amount as may
be advanced to or for the benefit of the Borrower hereunder, together with interest accruing on the outstanding principal balance from
the date hereof, all as provided below.

 

1.                 
Revolving Line of Credit Advances.
This Note evidences a revolving line of credit. The Borrower may borrow, repay and reborrow hereunder and the Bank may advance and readvance
under this Note from time to time (each an “advance” and together the “advances”) until the Expiration Date, subject
to the terms and conditions of this Note and the Loan Documents (as defined below). The “Expiration Date” shall mean
February 22, 2022, or such later date as may be designated by the Bank by written notice from the Bank to the Borrower. The Borrower
acknowledges and agrees that in no event will the Bank be under any obligation to extend or renew the Facility or this Note beyond the
Expiration Date. In no event shall the aggregate unpaid principal amount of advances under this Note exceed the face amount of this Note.

 

2.                 
Interest Rate and Payments. Amounts
outstanding under this Note will bear interest at a rate per annum which is at all times equal to the sum of (A) the Daily LIBOR Rate
(as defined below) plus (B) 250 basis points (2.50%). Accrued interest will be due and payable on the same day of each month, beginning
with the payment due on September 10, 2021. The outstanding principal balance and any accrued but unpaid interest shall be due and payable
on the Expiration Date.

 

3.                 
Certain Definitions. If the following
terms are used in this Note, such terms shall have the meanings set forth below:

 

“Alternate Rate” shall mean the Base Rate.

 

“Base Rate” shall mean the higher of (A) the
Prime Rate, and (B) the sum of the Overnight Bank Funding Rate plus 50 basis points (0.50%). If and when the Base Rate (or any
component thereof) changes, the rate of interest with respect to any amounts hereunder to which the Base Rate applies will change automatically
without notice to the Borrower, effective on the date of any such change.

 

“Business Day” shall mean any day other than
a Saturday or Sunday or a legal holiday on which commercial banks are authorized or required by law to be closed for business in Pittsburgh,
Pennsylvania.

 

“Daily LIBOR Rate” shall mean, for any day,
the rate per annum determined by the Bank by dividing

 

    - 1 -

     

    

 

the Published Rate by (B) a number equal to 1.00 minus
the percentage prescribed by the Federal Reserve for determining the maximum reserve requirements with respect to any eurocurrency fundings
by banks on such day; provided, however, if the Daily LIBOR Rate determined as provided above would be less than 50 basis
points, then such rate shall be deemed to be 50 basis points. The rate of interest will be adjusted automatically as of each Business
Day based on changes in the Daily LIBOR Rate without notice to the Borrower.

 

“Default Rate” shall mean the rate per annum
(based on the actual number of days that principal is outstanding over a year of 360 days) equal to the lesser of (A) the sum of 3% plus
the interest rate otherwise in effect from time to time under this Note and (B) the Maximum Rate.

 

“Maximum Rate” shall mean the maximum rate
of interest allowed by applicable law.

 

“Overnight Bank Funding Rate” shall mean,
for any day, the rate comprised of both overnight federal funds and overnight Eurocurrency borrowings by U.S.-managed banking offices
of depository institutions, as such composite rate shall be determined by the Federal Reserve Bank of New York (“NYFRB”),
as set forth on its public website from time to time, and as published on the next succeeding Business Day as the overnight bank funding
rate by the NYFRB (or by such other recognized electronic source (such as Bloomberg) selected by the Bank for the purpose of displaying
such rate); provided, that if such day is not a Business Day, the Overnight Bank Funding Rate for such day shall be such rate on the immediately
preceding Business Day; provided, further, that if such rate shall at any time, for any reason, no longer exist, a comparable replacement
rate determined by the Bank at such time (which determination shall be conclusive absent manifest error). If the Overnight Bank Funding
Rate determined as above would be less than zero, then such rate shall be deemed to be zero. The rate of interest charged shall be adjusted
as of each Business Day based on changes in the Overnight Bank Funding Rate without notice to the Borrower.

 

“Prime Rate” shall mean the rate publicly
announced by the Bank from time to time as its prime rate. The Prime Rate is determined from time to time by the Bank as a means of pricing
some loans to its borrowers. The Prime Rate is not tied to any external rate of interest or index, and does not necessarily reflect the
lowest rate of interest actually charged by the Bank to any particular class or category of customers.

 

“Published Rate” shall mean the rate of interest
published each Business Day in the Wall Street Journal “Money Rates” listing under the caption “London Interbank Offered
Rates” for a one month period (or, if no such rate is published therein for any reason, then the Published Rate shall be the eurodollar
rate for a one month period as published in another publication selected by the Bank).

 

4.                 
Advance Procedures. If permitted by
the Bank, a request for advance may be made by telephone or electronic mail, or delivered in accordance with the Bank’s security
procedures through any automated platform or electronic service provided by the Bank, with such confirmation or verification (if any)
as the Bank may require in its discretion from time to time. A request for advance by any Borrower shall be binding upon Borrower, jointly
and severally. The Borrower authorizes the Bank to accept telephonic, email, automated and electronic requests for advances, and the Bank
shall be entitled to rely upon the authority of any person providing such instructions. The Borrower hereby indemnifies and holds the
Bank harmless from and against any and all damages, losses, liabilities, costs and expenses (including reasonable attorneys’ fees
and expenses) which may arise or be created by the acceptance of such telephonic, email, automated and electronic requests or by the making
of such advances. The Bank will enter on its books and records, which entry when made will be presumed correct, the date and amount of
each advance, as well as the date and amount of each payment made by the Borrower.

 

 

    - 2 -

     

    

 

5.                 
Interest Calculation; Maximum Rate.
Interest will be calculated based on the actual number of days that principal is outstanding over a year of 360 days. In no event will
the rate of interest hereunder exceed the Maximum Rate. Regardless of any other provision of this Note or the other Loan Documents, if
for any reason the effective interest rate should exceed the Maximum Rate, the effective interest rate shall be deemed reduced to, and
shall be, the Maximum Rate, and (i) the amount which would be excessive interest shall be deemed applied to the reduction of the principal
balance of this Note and not to the payment of interest, and (ii) if the loan evidenced by this Note has been or is thereby paid in full,
the excess shall be returned to the party paying same, such application to the principal balance of this Note or the refunding of such
excess to be a complete settlement and acquittance thereof.

 

6.                 
Alternate LIBOR Rate Provisions. If
the Bank determines (which determination shall be final and conclusive) that, by reason of circumstances affecting the eurodollar market
generally, deposits in dollars (in the applicable amounts) are not being offered to banks in the eurodollar market for the selected term,
or adequate means do not exist for ascertaining the Daily LIBOR Rate, then the Bank shall give notice thereof to the Borrower. Thereafter,
until the Bank notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the interest rate for all
amounts outstanding under this Note shall be equal to the Alternate Rate.

 

In addition, if, after the date of this Note, the Bank shall determine
(which determination shall be final and conclusive) that any enactment, promulgation or adoption of or any change in any applicable law,
rule or regulation, or any change in the interpretation or administration thereof by a governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance by the Bank with any guideline, request or directive (whether
or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the
Bank to make or maintain or fund loans based on the Daily LIBOR Rate, the Bank shall notify the Borrower. Thereafter, until the Bank notifies
the Borrower that the circumstances giving rise to such determination no longer apply, the interest rate on all amounts outstanding under
this Note shall be the Alternate Rate.

 

The LIBOR Replacement Rider attached to this Note and incorporated herein
by this reference provides a mechanism for determining an alternative rate of interest in the event that the London interbank offered
rate is no longer available or in certain other circumstances. The Bank does not warrant or accept any responsibility for and shall not
have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or
other rates in the definition of “LIBOR” or with respect to any alternative or successor rate thereto, or replacement rate
therefor. To the extent that any term or provision of the LIBOR Replacement Rider is or may be inconsistent with any term or provision
in the remainder of this Note or any other Loan Document, the terms and provisions of the LIBOR Replacement Rider shall control.

 

7.                 
Other Payment Terms. If any payment
under this Note shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and
such extension of time shall be included in computing interest in connection with such payment. The Borrower hereby authorizes the Bank
to charge the Borrower’s deposit account at the Bank for any payment when due under this Note or any other Loan Document. Payments
received will be applied to charges, fees and expenses (including attorneys’ fees), accrued interest and principal in any order
the Bank may choose, in its sole discretion.

 

8.                 
Late Payments; Default Rate. If the
Borrower fails to make any payment of principal, interest or other amount coming due pursuant to the provisions of this Note within 15
calendar days of the date due and payable, the Borrower also shall pay to the Bank a late charge equal to the lesser of 5% of the amount
of such payment or $100.00 (the “Late Charge”). Such 15-day period shall not be construed in any way to extend the
due date of any such payment. Upon maturity, whether by acceleration, demand or otherwise, and at the Bank’s option upon the occurrence
of any Event of Default (as hereinafter defined) and during the continuance thereof, amounts outstanding under this Note shall bear interest
at the Default Rate. The Default Rate shall continue to apply whether or not judgment shall be entered on this Note. Both the Late Charge
and the Default Rate are imposed as liquidated damages for the purpose of defraying the Bank’s expenses incident to the handling
of delinquent payments, but are in addition to, and not in lieu of, the Bank’s exercise of any rights and remedies hereunder, under
the other Loan Documents or under applicable law, and any fees and expenses of any agents or attorneys which the Bank may employ. In addition,
the Default Rate reflects the increased credit risk to the Bank of carrying a loan that is in default. The Borrower agrees that the Late
Charge and Default Rate are reasonable forecasts of just compensation for anticipated and actual harm incurred by the Bank, and that the
actual harm incurred by the Bank cannot be estimated with certainty and without difficulty.

incurred, any losses suffered or payments made by the Bank as a result of any Change in Law (hereinafter defined), imposing any reserve,
deposit, allocation of capital or similar requirement (including without limitation, Regulation D of the Board of Governors of the Federal
Reserve System) on the Bank, its holding company or any of their respective assets relative to the Facility. “Change in Law”
means the occurrence, after the date of this Note, of any of the following: (a) the adoption or taking effect of any law, rule, regulation
or treaty, (b) any change in any law, rule, regulation or treaty or in the administration, interpretation, implementation or application
thereof by any governmental authority or (c) the making or issuance of any request, rule, guideline or directive (whether or not having
the force of law) by any governmental authority; provided that notwithstanding anything herein to the contrary, (x) the Dodd-Frank Wall
Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith
and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking
Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel
III, shall in each case be deemed to be a “Change in Law”, regardless of the date enacted, adopted or issued.

 

11.             
Other Loan Documents. This Note is
issued in connection with a letter agreement or loan agreement between the Borrower and the Bank, dated on or before the date hereof,
and the other agreements and documents executed and/or delivered in connection therewith or referred to therein, the terms of which are

any of the following events will be deemed to be an “Event of Default” under this Note: (i) the nonpayment of any principal,
interest or other indebtedness under this Note when due; (ii) the occurrence of any event of default or any default and the lapse of any

collateral if in the Bank’s opinion at any time or times, the market value of any of the collateral securing this Note or any guarantee
has depreciated below that required pursuant to the Loan Documents or, if no specific value is so required, then in an amount deemed material
by the Bank; (xii) the revocation or attempted revocation, in whole or in part, of any guarantee by any Obligor; or (xiii) the death,

such right or power. The Bank’s rights and remedies hereunder are cumulative and not exclusive of any other rights or remedies which
the Bank may have under other agreements, at law or in equity. No modification, amendment or waiver of, or consent to any departure by

professional or commercial activity, and not for personal, family or household purposes.

 

19.             
USA PATRIOT Act Notice. To help the
government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain,
verify and record information that identifies each Borrower that opens an account. What this means: when the Borrower opens an account,
the Bank will ask for the business name, business address, taxpayer identifying number and other information that will allow the Bank
to identify the Borrower, such as organizational documents. For some businesses and organizations, the Bank may also need to ask for identifying
information and documentation relating to certain individuals associated with the business or organization.

 

20.             
Representation by Counsel. The Borrower
hereby represents that it has been represented by competent counsel of its choice, or has knowingly waived its right to use and retain

on an ongoing basis, as necessary for the purposes of (a) update, renewal or extension of such credit or additional credit, (b) reviewing,
administering or collecting the resulting account and (c) reporting on the repayment and satisfaction of such credit obligations. By signing

Documents from a deposit account with the Bank (including due to the Borrower’s revocation of its authorization to do so or failure
to maintain such deposit account with the Bank or otherwise), the Bank may, at its option, upon 30 days’ notice to the Borrower,
increase the interest rate payable by the Borrower under this Note by 25 basis points (0.25%).

 

24.             
Depository. The Borrower will establish
and maintain with the Bank the Borrower’s primary depository accounts. If the Borrower fails to establish and/or maintain its primary
depository accounts with the Bank, the Bank may, at its option, upon 30 days’ notice to the Borrower, increase the interest rate

LIBOR Replacement Rider

 

(a)              
Announcements Related to LIBOR.
On March 5, 2021, the ICE Benchmark Administration, the administrator of LIBOR (the “IBA”) and the U.K. Financial Conduct
Authority, the regulatory supervisor for the IBA, announced in a public statement the future cessation or loss of representativeness of
overnight/Spot Next, 1-week, 1-month, 2-month, 3-month, 6-month and 12- month USD LIBOR tenor settings (collectively, the “Cessation
Announcements”). The parties hereto acknowledge that, as a result of the Cessation Announcements, a Benchmark Transition Event
occurred on March 5, 2021 with respect to USD LIBOR under clauses (1) and (2) of the definition of Benchmark Transition Event below; provided
however, no related Benchmark Replacement Date occurred as of such date.

 

(b)             
Benchmark Replacement.
Notwithstanding anything to the contrary herein or in any other Loan Document, if a Benchmark Transition Event or an Early Opt-in Election,
as applicable, and its related Benchmark Replacement Date have occurred in respect of any setting of the then-current Benchmark, then,
(x) if the Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement”
on the Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan
Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment or further action or consent of
any other party hereto or to any other Loan Document; and (y) if a Benchmark Replacement is determined in accordance with clause (3) of
the definition of “Benchmark Replacement” on the Benchmark Replacement Date, such Benchmark Replacement will replace such
Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (Eastern time)
on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Borrower without any amendment
hereto or to any other Loan Document, or further action or consent of the Borrower.

 

(c)              
Benchmark Replacement Conforming Changes.
In connection with the implementation of a Benchmark Replacement, the Bank will have the right to make Benchmark Replacement Conforming
Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing
such Benchmark Replacement Conforming Changes will become effective without any further action or consent of the Borrower.

 

(d)             
Notices; Standards for Decisions and Determinations.
The Bank will promptly notify the Borrower of (i) any occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early
Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark Replacement, (iii)
the effectiveness of any Benchmark Replacement Conforming Changes and (iv) the commencement or conclusion of any Benchmark Unavailability
Period. Any determination, decision or election that may be made by the Bank pursuant to this Rider, including any determination with
respect to a 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 the Borrower.

 

(e)              
Benchmark Unavailability Period.
Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, amounts outstanding hereunder automatically
will bear interest at the Fallback Rate. During any Benchmark Unavailability Period, the component of the Fallback Rate based upon the
then-current Benchmark, if any, will not be used in any determination of the Fallback Rate.

 

    - 11 -

     

    

 

(f)               
Secondary Term SOFR Conversion.
Notwithstanding anything to the contrary herein or in any other Loan Document and subject to the proviso below in this paragraph, if a
Term SOFR Transition Event and its related Benchmark Replacement Date have occurred in respect of any setting of the then-current Benchmark,
then (i) the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Loan Document
in respect of such Benchmark setting (the “Secondary Term SOFR Conversion Date”) and subsequent Benchmark settings,
without any amendment or further action or consent of any other party hereto or to any other Loan Document; and (ii) loans outstanding
on the Secondary Term SOFR Conversion Date bearing interest based on the then-current Benchmark shall be deemed to have been converted
to loans bearing interest at the Benchmark Replacement with a tenor approximately the same length as the interest payment period of the
then-current Benchmark; provided that, (A) this paragraph (f) shall not be effective unless the Bank has delivered to the Borrower a Term
SOFR Notice and (B) this paragraph (f) shall not be effective with respect to the Facility if (I) the Borrower has outstanding an interest
rate swap with the Bank to hedge, in whole or part, the floating rate risk under the Facility on the Secondary Term SOFR Conversion Date,
and (II) such swap incorporates LIBOR fallback provisions with a Daily Simple SOFR rate as the primary alternative fallback rate for USD
LIBOR.

 

(g)              
Certain Defined Terms.
As used in this Rider:

 

“Available Tenor” means, as of any
date of determination and with respect to the then-current Benchmark, as applicable, one month.

 

“Benchmark” means, initially, USD
LIBOR; provided that if a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its
related Benchmark Replacement Date have occurred with respect to USD LIBOR or the then-current Benchmark, then “Benchmark”
means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant
to paragraph (b) of this Rider.

 

“Benchmark Replacement” means for
the Available Tenor the first alternative set forth in the order below that can be determined by the Bank on the applicable Benchmark
Replacement Date; provided, however, if (i) the Borrower has outstanding an interest rate swap with the Bank on the Benchmark Replacement
Date to hedge, in whole or part, the floating rate risk under the Facility, and (ii) such swap incorporates LIBOR fallback provisions
with a Daily Simple SOFR rate as the primary alternative fallback rate for USD LIBOR, then the Benchmark Replacement alternative set forth
in clause (1) below shall not apply to the Facility and the alternative set forth below in clause (2) shall be the first alternative:

 

		(1)	the sum of: (a) Term SOFR and (b) the related Benchmark Replacement Adjustment;

 

		(2)	the sum of: (a) Daily Simple SOFR and (b) the related Benchmark Replacement
Adjustment;

 

		(3)	the sum of: (a) the alternate benchmark rate that has
been selected by the Bank as the replacement for the then-current Benchmark, giving due consideration to (i) any selection or recommendation
of a replacement benchmark rate or the mechanism for determining such a rate by the Relevant Governmental Body or (ii) any evolving or
then-prevailing market convention for determining a benchmark rate as a replacement for the then-current Benchmark for U.S. dollar-denominated
syndicated or bilateral credit facilities at such time, and (b) the related Benchmark Replacement Adjustment;

 

    - 12 -

     

    

 

provided that, in the case of clause (1), such Unadjusted Benchmark
Replacement is displayed on a screen or other information service that publishes such rate from time to time as selected by the Bank in
its reasonable discretion; provided, further, that, with respect to a Term SOFR Transition Event, on the applicable Benchmark
Replacement Date, the “Benchmark Replacement” shall revert to and shall be determined as set forth in clause (1) of this definition,
all in accordance with paragraph (f) (Secondary Term SOFR Conversion) above. If the Benchmark Replacement as determined pursuant to clause
(1), (2) or (3) above would be less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes hereof and
of the other Loan Documents.

 

“Benchmark Replacement Adjustment”
means, with respect to any replacement of the then-current Benchmark with an Unadjusted Benchmark Replacement for any setting of such
Unadjusted Benchmark Replacement:

 

		(1)	for purposes of clauses (1) and (2) of the definition
of “Benchmark Replacement,” 0.11448% (11.448 basis points). This value represents the ARRC/ISDA recommended spread adjustment
value for the Available Tenor available here: https://assets.bbhub.io/professional/sites/10/IBOR-Fallbacks-LIBOR- Cessation_Announcement_20210305.pdf.

 

		(2)	for purposes of clause (3) of the definition of “Benchmark Replacement,”
the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or
zero) that has been selected by the Bank, giving due consideration to (i) any selection or recommendation of a spread adjustment, or method
for calculating or determining such spread adjustment, for the replacement of such Available Tenor of such Benchmark with the applicable
Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or (ii) any evolving or
then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment,
for the replacement of such Available Tenor of such Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated
syndicated or bilateral credit facilities.

 

“Benchmark Replacement Conforming Changes”
means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition
of “Base Rate,” the definition of “Business Day,” the timing and frequency of determining rates and making payments
of interest, timing of borrowing requests or prepayment, length of lookback periods, the applicability of breakage provisions and other
technical, administrative or operational matters) that the Bank decides may be appropriate to reflect the adoption and implementation
of such Benchmark Replacement and to permit the administration thereof by the Bank in a manner substantially consistent with market practice
(or, if the Bank decides that adoption of any portion of such market practice is not administratively feasible or if the Bank determines
that no market practice for the administration of such Benchmark Replacement exists, in such other manner of administration as the Bank
decides is reasonably necessary in connection with the administration of the Facility and the Loan Documents).

 

“Benchmark Replacement Date” means
the earliest to occur of the following events with respect to the then-current Benchmark:

 

		(1)	in the case of clause (1) or (2) of the definition of “Benchmark Transition
Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which
the administrator of such Benchmark (or the published component used in the calculation thereof) permanently or indefinitely ceases to
provide the Available Tenor of such Benchmark (or such component thereof);

 

    - 13 -

     

    

 

		(2)	in the case of clause (3) of the definition of “Benchmark Transition
Event,” the date determined by the Bank, which date shall promptly follow the date of the public statement or publication of information
referenced therein;

 

		(3)	in the case of a Term SOFR Transition Event, the date that is set forth
in the Term SOFR Notice provided to the Borrower pursuant to this Rider, which date shall be at least 30 days from the date of the Term
SOFR Notice; or

 

		(4)	in the case of an Early Opt-in Election, the sixth (6th) Business Day after
the date notice of such Early Opt-in Election is provided to the Borrower.

 

“Benchmark Transition Event” means
the occurrence of one or more of the following events with respect to the then-current Benchmark:

 

		(1)	a public statement or publication of information by or on behalf of the
administrator of such Benchmark (or the published component used in the calculation thereof) announcing that such administrator has ceased
or will cease to provide the Available Tenor of such Benchmark (or such component thereof), permanently or indefinitely, provided that,
at the time of such statement or publication, there is no successor administrator that will continue to provide the Available Tenor of
such Benchmark (or such component thereof);

 

		(2)	a public statement or publication of information by a Governmental Authority
having jurisdiction over the Bank, the regulatory supervisor for the administrator of such Benchmark (or the published component used
in the calculation thereof), the Board of Governors of the Federal Reserve System, the Federal Reserve Bank of New York, an insolvency
official with jurisdiction over the administrator for such Benchmark (or such component), a resolution authority with jurisdiction over
the administrator for such Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over
