FOR VALUE RECEIVED, the undersigned promise(s) to
pay to the order of COMERICA BANK (herein called "Bank"), at any office of the Bank in the State of Texas, the principal
sum of TWENTY MILLION DOLLARS ($20,000,000.00), payable in monthly installments equal to the amounts set forth on the attached
Exhibit A, PLUS interest, commencing on January 1, 2022, and on each succeeding Installment Payment Date
thereafter, until the maturity date set forth above (the "Maturity Date"). On the Maturity Date, the entire unpaid balance
of principal, interest and all other sums hereunder shall be due and payable in full (unless sooner accelerated in accordance
with the terms of this Note).

 

This Note is a note under which an advance
is made, subject to the terms and conditions of this Note and that certain Credit Agreement dated effective as of November 1,
2017 between the undersigned and Bank (as the same has been and may be amended, restated or modified from time to time, the “Credit
Agreement”). Capitalized terms used herein and not otherwise defined herein will have the meaning given such terms in the
Credit Agreement.

 

Subject to the terms and conditions of
this Note, the unpaid principal balance of all Indebtedness outstanding under this Note from time to time shall bear interest at
the Prime Rate plus the Applicable Margin.

 

Interest accruing hereunder shall be computed
on the basis of a 360-day year if this Note evidences a business or commercial loan or a 365/366-day year if a consumer loan, and
shall be assessed for the actual number of days elapsed, and in such computation, effect shall be given to any change in the interest
rate as a result of any change in the Prime Rate on the date of each such change.

 

Accrued and unpaid interest on the unpaid
principal balance outstanding hereunder shall be payable, in arrears, on each Installment Payment Date, until all Indebtedness
outstanding under this Note is paid in full (whether in accordance with the terms hereof, by acceleration, or otherwise).

 

Payments under this Note shall be first
applied to accrued and unpaid interest hereunder and the balance, if any, to principal.

 

In the event the periodic installments
set forth above are inclusive of interest, the undersigned hereby acknowledge(s) and agree(s) that such installments
are based upon the original principal amount of Indebtedness outstanding under this Note, an assumed fixed rate of interest, and
an assumed amortization term, notwithstanding the fact that the applicable interest rate may change from time to time during the
term of this Note. Therefore, in the event that the applicable interest rate change(s) at any time as a result of any change(s) in
the Prime Rate, Bank may, in its sole discretion, recalculate the installments of principal and interest required to be made by
the undersigned under and pursuant to the terms of this Note, and the undersigned agree(s) to pay such installments as they
may be recalculated by Bank, and the undersigned acknowledge(s) and agree(s) that any such recalculation shall not affect
the Maturity Date of this Note or any other terms or provisions herein set forth.

 

From and after the occurrence of any Default
hereunder, and so long as any such Default remains unremedied or uncured thereafter, the Indebtedness outstanding under this Note
shall bear interest at a per annum rate of three percent (3%) above the otherwise applicable interest rate, which interest shall
be payable upon demand. In addition to the foregoing, a late payment charge equal to five percent (5%) of each late payment hereunder
may be charged on any payment not received by Bank within ten (10) calendar days after the payment due date therefor, but
acceptance of payment of any such charge shall not constitute a waiver of any Default hereunder.

 

In no event shall the interest payable
under this Note at any time exceed the Maximum Rate. The term "Maximum Rate", as used herein, shall mean at the particular
time in question the maximum nonusurious rate of interest which, under applicable law, may then be charged on this Note. If on
any day the applicable interest rate hereunder in respect of any Indebtedness under this Note shall exceed the Maximum Rate for
that day, the rate of interest applicable to such Indebtedness shall be fixed at the Maximum Rate on that day and on each day thereafter
until the total amount of interest accrued on the unpaid principal balance of this Note equals the total amount of interest which
would have accrued if there had been no Maximum Rate. If such maximum rate of interest changes after the date hereof, the Maximum
Rate shall be automatically increased or decreased, as the case may be, without notice to the undersigned from time to time as
of the effective date of each change in such maximum rate. For purposes of determining the Maximum Rate under the law of the State
of Texas, the applicable interest rate ceiling shall be the "weekly ceiling" from time to time in effect under Chapter
303 of the Texas Finance Code, as amended.

 

The amount from time to time outstanding
under this Note, the applicable interest rate and the amount and date of any repayment shall be noted on Bank's records, which
records shall be conclusive evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation,
or any error in any such notation, shall not relieve the undersigned of its/their obligations to repay Bank all amounts payable
by the undersigned to Bank under or pursuant to this Note, when due in accordance with the terms hereof.

 

Second Amended and Restated Term Note

 

    -1- 

     

    

 

In the event that any payment under this
Note becomes due and payable on any day which is not a Business Day, the due date thereof shall be extended to the next succeeding
Business Day, and, to the extent applicable, interest shall continue to accrue and be payable thereon during such extension at
the rate set forth in this Note.

 

All payments to be made by the undersigned
to Bank under or pursuant to this Note shall be in immediately available United States funds, without setoff or counterclaim, and
in the event that any payments submitted hereunder are in funds not available until collected, said payments shall continue to
bear interest until collected.

 

The undersigned may prepay all or any part
of the outstanding balance of any Indebtedness hereunder at any time without premium or penalty. Any prepayment hereunder shall
also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid. Partial prepayments hereunder shall
be applied to the installments hereunder in the inverse order of their maturities.

 

If any Change in Law shall (a) subject
Bank to any tax, duty or other charge with respect to this Note or any Indebtedness hereunder, or shall change the basis of taxation
of payments to Bank of the principal of or interest under this Note or any other amounts due under this Note in respect thereof
(except for changes in the rate of tax on the overall net income of Bank imposed by the jurisdiction in which Bank's principal
executive office is located); or (b) impose, modify or deem applicable any reserve (including, without limitation, any imposed
by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with
or for the account of, or credit extended by Bank, or shall impose on Bank or the foreign exchange and interbank markets any other
condition affecting this Note or the Indebtedness hereunder; and the result of any of the foregoing is to increase the cost to
Bank of maintaining any part of the Indebtedness hereunder or to reduce the amount of any sum received or receivable by Bank under
this Note by an amount deemed by the Bank to be material, then the undersigned shall pay to Bank, within fifteen (15) days of the
undersigned's receipt of written notice from Bank demanding such compensation, such additional amount or amounts as will compensate
Bank for such increased cost or reduction. A certificate of Bank, prepared in good faith and in reasonable detail by Bank and submitted
by Bank to the undersigned, setting forth the basis for determining such additional amount or amounts necessary to compensate Bank
shall be conclusive and binding for all purposes, absent manifest error.

 

In the event that any Change in Law affects
or would affect the amount of capital or liquidity required or expected to be maintained by Bank (or any corporation controlling
Bank), and Bank determines that the amount of such capital or liquidity is increased by or based upon the existence of any obligations
of Bank hereunder or the maintaining of any Indebtedness hereunder, and such increase has the effect of reducing the rate of return
on Bank's (or such controlling corporation's) capital as a consequence of such obligations or the maintaining of such Indebtedness
hereunder to a level below that which Bank (or such controlling corporation) could have achieved but for such circumstances (taking
into consideration its policies with respect to capital adequacy and liquidity), then the undersigned shall pay to Bank, within
fifteen (15) days of the undersigned's receipt of written notice from Bank demanding such compensation, additional amounts as are
sufficient to compensate Bank (or such controlling corporation) for any increase in the amount of capital and/or liquidity and
reduced rate of return which Bank reasonably determines to be allocable to the existence of any obligations of the Bank hereunder
or to maintaining any Indebtedness hereunder. A certificate of Bank as to the amount of such compensation, prepared in good faith
and in reasonable detail by the Bank and submitted by Bank to the undersigned, shall be conclusive and binding for all purposes
absent manifest error.

 

This Note and any other indebtedness are
secured by and the Bank is granted a security interest in and lien upon all Collateral. Notwithstanding the above, (i) to
the extent that any portion of the Indebtedness is a consumer loan, that portion shall not be secured by any deed of trust or mortgage
on or other security interest in any of the undersigned's principal dwelling or in any of the undersigned's real property which
is not a purchase money security interest as to that portion, unless expressly provided to the contrary in another place, or (ii) if
the undersigned (or any of them) has (have) given or give(s) Bank a deed of trust or mortgage covering California real property,
that deed of trust or mortgage shall no t secure this Note or any other indebtedness of the undersigned (or any of them), unless
expressly provided to the contrary in another place, or (iii) if the undersigned (or any of them) has (have) given or give(s) the
Bank a deed of trust or mortgage covering real property which, under Texas law, constitutes the homestead of such person, that
deed of trust or mortgage shall not secure this Note or any other indebtedness of the undersigned (or any of them) unless expressly
provided to the contrary in another place.

 

Upon the occurrence and during the continuance
or existence of an Event of Default, the Bank may, at its option and without prior notice to the undersigned (or any of them),
cease advancing money or extending credit to or for the benefit of the undersigned under this Note or any other Loan Document,
terminate this Note as to any future liability or obligation of Bank, but without affecting Bank's rights and security interests
in any Collateral and the Indebtedness of the undersigned to Bank, declare any or all of the Indebtedness to be immediately due
and payable (notwithstanding any provisions contained in the evidence of it to the contrary), sell or liquidate all or any portion
of the Collateral, set off against the Indebtedness any amounts owing by the Bank to the undersigned (or any of them), charge interest
at the default rate provided in the document evidencing the relevant Indebtedness and exercise any one or more of the rights and
remedies granted to the Bank by any agreement with the undersigned (or any of them) or given to it under applicable law.

 

The undersigned authorize(s) the Bank
to charge any account(s) of the undersigned (or any of them) with the Bank for any and all sums due hereunder when due; provided,
however, that such authorization shall not affect any of the undersigned's obligation to pay to the Bank all amounts when due,
whether or not any such account balances that are maintained by the undersigned with the Bank are insufficient to pay to the Bank
any amounts when due, and to the extent that such accounts are insufficient to pay to the Bank all such amounts, the undersigned
shall remain liable for any deficiencies until paid in full.

If this Note is signed by two or more parties
(whether by all as makers or by one or more as an accommodation party or otherwise), the obligations and undertakings under this
Note shall be that of all and any two or more jointly and also of each severally. This Note shall bind the undersigned, and the
undersigned's respective heirs, personal representatives, successors and assigns.

 

The undersigned waive(s) presentment,
demand, protest, notice of dishonor, notice of demand or intent to demand, notice of acceleration or intent to accelerate, and
all other notices, and agree(s) that no extension or indulgence to the undersigned (or any of them) or release, substitution
or nonenforcement of any security, or release or substitution of any of the undersigned, any guarantor or any other party, whether
with or without notice, shall affect the obligations of any of the undersigned. The undersigned waive(s) all defenses or right
to discharge available under Section 3-605 of the Uniform Commercial Code and waive(s) all other suretyship defenses
or right to discharge. The undersigned agree(s) that the Bank has the right to sell, assign, or grant participations or any
interest in, any or all of the Indebtedness, and that, in connection with this right, but without limiting its ability to make
other disclosures to the full extent allowable, the Bank may disclose all documents and information which the Bank now or later
has relating to the undersigned or the Indebtedness. The undersigned agree(s) that the Bank may provide information relating
to this Note or relating to the undersigned to the Bank's parent, affiliates, subsidiaries and service providers.

 

The undersigned agree(s) to pay or
reimburse to Bank, or any other holder or owner of this Note, on demand, (a) all actual, out-of-pocket costs, expenses, fees
and charges paid or incurred by Bank (including, without limitation, Bank's reasonable attorneys' fees and costs and/or fees and
transfer charges in connection with the preparation, closing and consummation of this Note and/or the other Loan Documents and/or
the Loans or transactions contemplated hereby or thereby, or in connection with the administration of this Note or the Indebtedness
and (b) all costs, expenses, fees and charges paid or incurred by Bank (including, without limitation, Bank's attorneys' fees
and costs and/or fees, transfer charges and costs of Bank's in-house counsel), in connection with the enforcement in any other
matter or proceeding relating to this Note or the Indebtedness.

 

The undersigned acknowledge(s) and
agree(s) that there are no contrary agreements, oral or written, establishing a term of this Note and agree(s) that the
terms and conditions of this Note may not be amended, waived or modified except in a writing signed by an officer of the Bank expressly
stating that the writing constitutes an amendment, waiver or modification of the terms of this Note. As used in this Note, the
word "undersigned" means, individually and collectively, each maker, accommodation party, endorser and other party signing
this Note in a similar capacity. If any provision of this Note is unenforceable in whole or part for any reason, the remaining
provisions shall continue to be effective. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS
OF THE STATE OF Texas, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES. Chapter
346 of the Texas Finance Code (and as the same may be incorporated by reference in other Texas statutes) shall not apply to the
Indebtedness evidenced by this Note.

 

This Note and all other Loan Documents
(whether executed and delivered prior to, concurrently with or subsequent to this Note), as such Loan Documents may have been or
may hereafter be amended from time to time are intended to be performed in accordance with, and only to the extent permitted by,
all applicable usury laws. If any provision hereof or of any of the other Loan Documents or the application thereof to any person
or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision
to any other person or circumstance nor the remainder of the instrument in which such provision is contained shall be affected
thereby and shall be enforced to the greatest extent permitted by law. It is expressly stipulated and agreed to be the intent of
the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable
on the indebtedness evidenced by this Note. If the applicable law is ever revised, repealed or judicially interpreted so as to
render usurious any amount called for under this Note or under any of the other Loan Documents, or contracted for, charged, taken,
reserved or received with respect to the indebtedness evidenced by this Note, or if Bank's exercise of the option to accelerate
the maturity of this Note, or if any prepayment by the undersigned or prepayment agreement results (or would, if complied with,
result) in the undersigned having paid, contracted for or being charged for any interest in excess of that permitted by law, then
it is the express intent of the undersigned and Bank that this Note and the other Loan Documents shall be limited to the extent
necessary to prevent such result and all excess amounts theretofore collected by Bank shall be credited on the principal balance
of this Note or, if fully paid, upon such other Indebtedness as shall then remain outstanding (or, if this Note and all other Indebtedness
have been paid in full, refunded to the undersigned), and the provisions of this Note and the other Loan Documents shall immediately
be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the necessity of the execution
of any new document, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise
called for hereunder or thereunder. All sums paid, or agreed to be paid, by the undersigned for the use, forbearance, detention,
taking, charging, receiving or reserving of the indebtedness of the undersigned to Bank under this Note or arising under or pursuant
to the other Loan Documents shall, to the maximum extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness
does not exceed the usury ceiling from time to time in effect and applicable to such indebtedness for so long as such indebtedness
is outstanding. To the extent federal law permits Bank to contract for, charge or receive a greater amount of interest, Bank will
rely on federal law instead of the Texas Finance Code, as supplemented by Texas Credit Title, for the purpose of determining the
Maximum Rate. Additionally, to the maximum extent permitted by applicable law now or hereafter in effect, Bank may, at its option
and from time to time, implement any other method of computing the Maximum Rate under the Texas Finance Code, as supplemented by
Texas Credit Title, or under other applicable law, by giving notice, if required, to the undersigned as provided by applicable
law now or hereafter in effect. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents,
it is not the intention of Bank to accelerate the maturity of any interest that has not accrued at the time of such acceleration
or to collect unearned interest at the time of such acceleration.

On or before the Maturity Date set forth
above (the "Maturity Date"), FOR VALUE RECEIVED, the undersigned promise(s) to pay to the order of COMERICA BANK
(herein called "Bank"), at any office of the Bank in the State of Texas, the principal sum of THREE MILLION and NO/100
DOLLARS ($3,000,000.00), or so much of said sum as has been advanced and is then outstanding under this Note, together with interest

principal balance of each outstanding Advance hereunder shall be payable monthly, in arrears, on the first Business Day of each
month, from the date made until the same is paid in full (whether in accordance with the terms hereof, by acceleration, or otherwise).
Interest accruing hereunder shall be computed on the basis of a year of 360 days, and shall be assessed for the actual number of
days elapsed, and in such computation, effect shall be given to any change in the interest rate as a result of any change in the
Prime Rate on the date of each such change.

 

From and after the occurrence of any Default
hereunder, and so long as any such Default remains unremedied or uncured thereafter, the Indebtedness outstanding under this Note
shall bear interest at a per annum rate of three percent (3%) above the otherwise applicable interest rate, which interest shall
be payable upon demand. In addition to the foregoing, a late payment charge equal to five percent (5%) of each late payment hereunder
may be charged on any payment not received by Bank within ten (10) calendar days after the payment due date therefor, but
acceptance of payment of any such charge shall not constitute a waiver of any Default hereunder.

 

In no event shall the interest payable
under this Note at any time exceed the Maximum Rate. The term "Maximum Rate", as used herein, shall mean at the particular
time in question the maximum nonusurious rate of interest which, under applicable law, may then be charged on this Note. If on
any day the applicable interest rate hereunder in respect of any Indebtedness under this Note shall exceed the Maximum Rate for
that day, the rate of interest applicable to such Indebtedness shall be fixed at the Maximum Rate on that day and on each day thereafter
until the total amount of interest accrued on the unpaid principal balance of this Note equals the total amount of interest which
would have accrued if there had been no Maximum Rate. If such maximum rate of interest changes after the date hereof, the Maximum
Rate shall be automatically increased or decreased, as the case may be, without notice to the undersigned from time to time as
of the effective date of each change in such maximum rate. For purposes of determining the Maximum Rate under the law of the State
of Texas, the applicable interest rate ceiling shall be the "weekly ceiling" from time to time in effect under Chapter
303 of the Texas Finance Code, as amended.

 

The amount and date of each Advance, the
applicable interest rate and the amount and date of any repayment shall be noted on Bank's records, which records shall be conclusive
evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation, or any
error in any such notation, shall not relieve the undersigned of its/their obligations to repay Bank all amounts payable by the
undersigned to Bank under or pursuant to this Note, when due in accordance with the terms hereof.

 

The undersigned may request an Advance
hereunder either (i) upon the delivery to Bank of a written Request for Advance duly completed and executed by the undersigned
(as herein provided) or, (ii) to the extent applicable, pursuant to a request submitted through Bank's Loan Management System
(each a "Request"), in each case, subject to the following: (a) no Default, or any condition or event which, with
the giving of notice or the running of time, or both, would constitute a Default, shall have occurred and be continuing or exist
under this Note; (b) each such Request shall be delivered to Bank by 11:00 a.m. (Detroit, Michigan time) on the proposed
date of the requested Advance; (c) after giving effect to such Advance, the aggregate principal amount of Advances made under
this Note (excluding refundings and conversions of outstanding Advances) shall not exceed the Loan Amount; and (d) a Request,
once delivered or submitted to Bank, shall not be revocable by the undersigned.

In the event that the undersigned is unable
to request Advances hereunder through the Bank's Loan Management System, Advances hereunder may be requested by delivery or submission
to Bank by hand delivery, first class mail, overnight courier, facsimile, email or other means of delivery acceptable to Bank,
of a written Request for Advance duly completed and executed by the undersigned. Advances hereunder may be requested in the undersigned's
discretion by telephonic notice to Bank. Any Advance requested by telephonic notice shall be confirmed by the undersigned that
same day by submission to Bank of a written Request for Advance, as provided herein. The undersigned acknowledge(s) that if
Bank makes an Advance based on a request made by telephone, facsimile, email or other means of delivery (other than by hand delivery,
first class mail or overnight courier), it shall be for the undersigned's convenience and all risks involved in the use of any
such procedure shall be borne by the undersigned, and the undersigned expressly agree(s) to indemnify and hold Bank harmless
therefor. Bank shall have no duty to confirm the authority of anyone requesting an Advance by telephone, facsimile, email or any
such other means of delivery. In the event that the undersigned elect(s) to request Advances by telephonic notice, facsimile,
email or other means of delivery acceptable to Bank, the undersigned acknowledge(s) and agree(s) that Bank may impose
or require such verification, authentication and other procedures as Bank may require from time to time.

 

In the event that any payment under this
Note becomes due and payable on any day which is not a Business Day, the due date thereof shall be extended to the next succeeding
Business Day, and, to the extent applicable, interest shall continue to accrue and be payable thereon during such extension at
the rate set forth in this Note.

 

All payments to be made by the undersigned
to Bank under or pursuant to this Note shall be in immediately available United States funds, without setoff or counterclaim, and
in the event that any payments submitted hereunder are in funds not available until collected, said payments shall continue to
bear interest until collected.

 

The undersigned may prepay all or part
of the outstanding balance of any Indebtedness hereunder at any time without premium or penalty. Any prepayment hereunder shall
also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid.

 

If any Change in Law shall (a) subject
Bank to any tax, duty or other charge with respect to this Note or any Indebtedness hereunder, or shall change the basis of taxation
of payments to Bank of the principal of or interest under this Note or any other amounts due under this Note in respect thereof
(except for changes in the rate of tax on the overall net income of Bank imposed by the jurisdiction in which Bank's principal
executive office is located); or (b) impose, modify or deem applicable any reserve (including, without limitation, any imposed
by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with
or for the account of, or credit extended by Bank, or shall impose on Bank or the foreign exchange and interbank markets any other
condition affecting this Note or the Indebtedness hereunder; and the result of any of the foregoing is to increase the cost to
Bank of maintaining any part of the Indebtedness hereunder or to reduce the amount of any sum received or receivable by Bank under
this Note by an amount deemed by the Bank to be material, then the undersigned shall pay to Bank, within fifteen (15) days of the
undersigned's receipt of written notice from Bank demanding such compensation, such additional amount or amounts as will compensate
Bank for such increased cost or reduction. A certificate of Bank, prepared in good faith and in reasonable detail by Bank and submitted
by Bank to the undersigned, setting forth the basis for determining such additional amount or amounts necessary to compensate Bank
shall be conclusive and binding for all purposes, absent manifest error.

 

In the event that any Change in Law affects
or would affect the amount of capital or liquidity required or expected to be maintained by Bank (or any corporation controlling
Bank), and Bank determines that the amount of such capital or liquidity is increased by or based upon the existence of any obligations
of Bank hereunder or the maintaining of any Indebtedness hereunder, and such increase has the effect of reducing the rate of return
on Bank's (or such controlling corporation's) capital as a consequence of such obligations or the maintaining of such Indebtedness
hereunder to a level below that which Bank (or such controlling corporation) could have achieved but for such circumstances (taking
into consideration its policies with respect to capital adequacy and liquidity), then the undersigned shall pay to Bank, within
fifteen (15) days of the undersigned's receipt of written notice from Bank demanding such compensation, additional amounts as are
sufficient to compensate Bank (or such controlling corporation) for any increase in the amount of capital and/or liquidity and
reduced rate of return which Bank reasonably determines to be allocable to the existence of any obligations of the Bank hereunder
or to maintaining any Indebtedness hereunder. A certificate of Bank as to the amount of such compensation, prepared in good faith
and in reasonable detail by the Bank and submitted by Bank to the undersigned, shall be conclusive and binding for all purposes
absent manifest error.

This Note and any other indebtedness and
liabilities of any kind of the undersigned (or any of them) to the Bank, and any and all modifications, renewals or extensions
of it, whether joint or several, contingent or absolute, now existing or later arising, and however evidenced and whether incurred

by Bank including, without limitation, any late charges; loan fees or charges; overdraft indebtedness; costs incurred by Bank in
establishing, determining, continuing or defending the validity or priority of any security interest, pledge or other lien or in

and paralegals, whether inside or outside counsel is used, and whether any suit or other action is instituted, and to court costs
if suit or action is instituted, and whether any such fees, costs or expenses are incurred at the trial court level or on appeal,

secured by and the Bank is granted a security interest in and lien upon all items deposited in any account of any of the undersigned
with the Bank and by all proceeds of these items (cash or otherwise), all account balances of any of the undersigned from time
to time with the Bank, by all property of any of the undersigned from time to time in the possession of the Bank and by any other
collateral, rights and properties described in each and every deed of trust, mortgage, security agreement, pledge, assignment and
other security or collateral agreement which has been, or will at any time(s) later be, executed by any (or all) of the undersigned
to or for the benefit of the Bank (collectively "Collateral"). Notwithstanding the above, (i) to the extent that
any portion of the Indebtedness is a consumer loan, that portion shall not be secured by any deed of trust or mortgage on or other
security interest in any of the undersigned's principal dwelling or in any of the undersigned's real property which is not a purchase
money security interest as to that portion, unless expressly provided to the contrary in another place, or (ii) if the undersigned
(or any of them) has (have) given or give(s) Bank a deed of trust or mortgage covering California real property, that deed
of trust or mortgage shall not secure this Note or any other indebtedness of the undersigned (or any of them), unless expressly
provided to the contrary in another place, or (iii) if the undersigned (or any of them) has (have) given or give(s) the
Bank a deed of trust or mortgage covering real property which, under Texas law, constitutes the homestead of such person, that

provided to the contrary in another place.

 

Upon the occurrence and during the continuance

money or extending credit to or for the benefit of the undersigned under this Note or any other Loan Document, terminate this Note
as to any future liability or obligation of Bank, but without affecting Bank's rights and security interests in any Collateral
and the Indebtedness of the undersigned to Bank, declare any or all of the Indebtedness to be immediately due and payable (notwithstanding
any provisions contained in the evidence of it to the contrary), sell or liquidate all or any portion of the Collateral, set off
against the Indebtedness any amounts owing by the Bank to the undersigned (or any of them), charge interest at the default rate
provided in the document evidencing the relevant Indebtedness and exercise any one or more of the rights and remedies granted to

The undersigned authorize(s) the Bank
to charge any account(s) of the undersigned (or any of them) with the Bank for any and all sums due hereunder when due; provided,
however, that such authorization shall not affect any of the undersigned's obligation to pay to the Bank all amounts when
due, whether or not any such account balances that are maintained by the undersigned with the Bank are insufficient to pay to the
Bank any amounts when due, and to the extent that such accounts are insufficient to pay to the Bank all such amounts, the undersigned
shall remain liable for any deficiencies until paid in full.

 

If this Note is signed by two or more parties
(whether by all as makers or by one or more as an accommodation party or otherwise), the obligations and undertakings under this
Note shall be that of all and any two or more jointly and also of each severally. This Note shall bind the undersigned, and the
undersigned's respective heirs, personal representatives, successors and assigns.

 

The undersigned waive(s) presentment,
demand, protest, notice of dishonor, notice of demand or intent to demand, notice of acceleration or intent to accelerate, and
all other notices, and agree(s) that no extension or indulgence to the undersigned (or any of them) or release, substitution

with or without notice, shall affect the obligations of any of the undersigned. The undersigned waive(s) all defenses or right
to discharge available under Section 3-605 of the Uniform Commercial Code and waive(s) all other suretyship defenses
or right to discharge. The undersigned agree(s) that the Bank has the right to sell, assign, or grant participations or any
interest in, any or all of the Indebtedness, and that, in connection with this right, but without limiting its ability to make
other disclosures to the full extent allowable, the Bank may disclose all documents and information which the Bank now or later
has relating to the undersigned or the Indebtedness. The undersigned agree(s) that the Bank may provide information relating
to this Note or relating to the undersigned to the Bank's parent, affiliates, subsidiaries and service providers.

the Loans or transactions contemplated hereby or thereby, or in connection with the administration of this Note or the Indebtedness
and (b) all costs, expenses, fees and charges paid or incurred by Bank (including, without limitation, Bank's attorneys' fees

OF THE STATE OF Texas, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES. Chapter
346 of the Texas Finance Code (and as the same may be incorporated by reference in other Texas statutes) shall not apply to the

Second Amended and Restated Master Revolving Note

 

    -3- 

     

    

 

This Note and all other Loan Documents
(whether executed and delivered prior to, concurrently with or subsequent to this Note), as such Loan Documents may have been or
may hereafter be amended from time to time are intended to be performed in accordance with, and only to the extent permitted by,
all applicable usury laws. If any provision hereof or of any of the other Loan Documents or the application thereof to any person
or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision
to any other person or circumstance nor the remainder of the instrument in which such provision is contained shall be affected
thereby and shall be enforced to the greatest extent permitted by law. It is expressly stipulated and agreed to be the intent of
the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable
on the indebtedness evidenced by this Note. If the applicable law is ever revised, repealed or judicially interpreted so as to
render usurious any amount called for under this Note or under any of the other Loan Documents, or contracted for, charged, taken,
reserved or received with respect to the indebtedness evidenced by this Note, or if Bank's exercise of the option to accelerate
the maturity of this Note, or if any prepayment by the undersigned or prepayment agreement results (or would, if complied with,
result) in the undersigned having paid, contracted for or being charged for any interest in excess of that permitted by law, then
it is the express intent of the undersigned and Bank that this Note and the other Loan Documents shall be limited to the extent
necessary to prevent such result and all excess amounts theretofore collected by Bank shall be credited on the principal balance
of this Note or, if fully paid, upon such other Indebtedness as shall then remain outstanding (or, if this Note and all other Indebtedness
have been paid in full, refunded to the undersigned), and the provisions of this Note and the other Loan Documents shall immediately
be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the necessity of the execution
of any new document, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise
called for hereunder or thereunder. All sums paid, or agreed to be paid, by the undersigned for the use, forbearance, detention,
taking, charging, receiving or reserving of the indebtedness of the undersigned to Bank under this Note or arising under or pursuant
to the other Loan Documents shall, to the maximum extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness
does not exceed the usury ceiling from time to time in effect and applicable to such indebtedness for so long as such indebtedness
is outstanding. To the extent federal law permits Bank to contract for, charge or receive a greater amount of interest, Bank will
rely on federal law instead of the Texas Finance Code, as supplemented by Texas Credit Title, for the purpose of determining the
Maximum Rate. Additionally, to the maximum extent permitted by applicable law now or hereafter in effect, Bank may, at its option
and from time to time, implement any other method of computing the Maximum Rate under the Texas Finance Code, as supplemented by
Texas Credit Title, or under other applicable law, by giving notice, if required, to the undersigned as provided by applicable
law now or hereafter in effect. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents,
it is not the intention of Bank to accelerate the maturity of any interest that has not accrued at the time of such acceleration
or to collect unearned interest at the time of such acceleration.

 

For the purposes of this Note, the following
terms have the following meanings:

 

"Advance" means a borrowing requested
by the undersigned and made by Bank under this Note.

 

"Applicable Margin" means (a) for

Applicable Margin shall be increased by one quarter of a percent.

 

"Business Day" means any day,
other than a Saturday, Sunday or any other day designated as a holiday under Federal or applicable State statute or regulation,
on which Bank is open for all or substantially all of its domestic and international business (including dealings in foreign exchange)
in Detroit, Michigan.

 

"Change in Law" means the occurrence,
after the date hereof, of any of the following: (i) the adoption or introduction of, or any change in any applicable law,
treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not applicable to Bank
on such date, or (ii) any change in interpretation, administration or implementation thereof of any such law, treaty, rule or
regulation by any Governmental Authority, or (iii) the issuance, making or implementation by any Governmental Authority of
any interpretation, administration, request, regulation, guideline, or directive (whether or not having the force of law), including,
without limitation, any risk-based capital guidelines or any interpretation, administration, request, regulation, guideline, or
directive relating to liquidity. For purposes of this definition, (x) a change in law, treaty, rule, regulation, interpretation,
administration or implementation shall include, without limitation, any change made or which becomes effective on the basis of
a law, treaty, rule, regulation, interpretation administration or implementation then in force, the effective date of which change
is delayed by the terms of such law, treaty, rule, regulation, interpretation, administration or implementation, and (y) the
Dodd-Frank Wall Street Reform and Consumer Protection Act (Pub. L. 111-203, H.R. 4173) and all requests, rules, regulations,
guidelines, interpretations or directives promulgated thereunder or issued in connection therewith shall be deemed to be a "Change
in Law", regardless of the date enacted, adopted, issued or promulgated, whether before or after the date hereof, and (z) 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 regulatory authorities, in each case pursuant to Basel
III, shall each be deemed to be a "Change in Law", regardless of the date enacted, adopted, issued or implemented.

 

"Governmental Authority" means
the government of the United States of America or any other nation, or of any political subdivision thereof, whether state or local,
and any agency, authority, instrumentality, regulatory body, court, central bank or other entity exercising executive, legislative,
judicial, taxing, regulatory or administrative powers or functions of or pertaining to government (including, without limitation,
any supranational bodies such as the European Union or the European Central Bank).

per annum.

 

"Request for Advance" means a
Request for Advance issued by the undersigned under this Note in the form annexed to this Note as Exhibit "A".

preclude any further exercise thereof, or the exercise of any other power, right or privilege. The rights of Bank under this Note
are cumulative and not exclusive of any right or remedies which Bank would otherwise have, whether by other instruments or by law.

 

THE UNDERSIGNED AND BANK, BY ACCEPTANCE
OF THIS NOTE, ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN
CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL
OF THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION
REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS NOTE OR THE INDEBTEDNESS.

 

THIS WRITTEN LOAN AGREEMENT (AS DEFINED
BY SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE) REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT
BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

 

This Note amends, restates, supersedes
and replaces that certain Amended and Restated Master Revolving Note dated March 1, 2019, made in the principal amount of
Three Million Five Hundred Thousand Dollars (3,500,000.00) by the undersigned payable to the Bank, as amended (the "Prior
Note"); provided, however, (i) the execution and delivery by the undersigned of this Note shall not, in any manner or
circumstance, be deemed to be a payment of, a novation of or to have terminated, extinguished or discharged any of the undersigned's
indebtedness evidenced by the Prior Note, all of which indebtedness shall continue under and shall hereinafter be evidenced and
governed by this Note, and (ii) all Collateral and guaranties securing or supporting the Prior Note shall continue to secure
and support this Note.

REQUEST FOR ADVANCE

 

The
undersigned hereby request(s) COMERICA BANK ("Bank") to make an Advance to the undersigned on                 ,
in the amount of                          Dollars

of THREE MILLION and NO/100 Dollars ($3,000,000.00) (the "Note").

 

The undersigned represent(s),
warrant(s) and certify(ies) that no Default, or any condition or event which, with the giving of notice or the running of
time, or both, would constitute a Default, has occurred and is continuing under the Note, and none will exist upon the making of
the Advance requested hereunder. The undersigned further certify(ies) that upon advancing the sum requested hereunder, the aggregate
principal amount outstanding under the Note will not exceed the face amount thereof. If the amount advanced to the undersigned
under the Note shall at any time exceed the face amount thereof, the undersigned will immediately pay such excess amount, without
any necessity of notice or demand.

 

The undersigned hereby
authorize(s) Bank to disburse the proceeds of the Advance being requested by this Request for Advance by crediting the account
of the undersigned with Bank separately designated by the undersigned.

 

Capitalized terms used
but not otherwise defined herein shall have the respective meanings given to them in the Note.
