Prime Rate means the rate of interest per annum announced from time to time by the Payee as its prime rate. The Prime

and any successor thereto or other regulation or official interpretation of said Board of Governors relating to reserve requirements applicable to member banks of the Federal Reserve System.

2.3. Interest Limitation Recoupment. Notwithstanding anything in this
Note to the contrary, if at any time (i) interest at the Applicable Rate, and (ii) the Charges computed over the full term of this Note, exceed the Maximum Lawful Rate, then the rate of interest payable hereunder, together with all
Charges, shall be limited to the Maximum Lawful Rate; provided, however, that any subsequent reduction in the Applicable Rate shall not cause a reduction of the rate of interest payable hereunder below the Maximum Lawful Rate until the total amount
of interest earned hereunder, together with all Charges, equals the total amount of interest which would have accrued at the Applicable Rate if such interest rate had at all times been in effect. Changes in the Applicable Rate resulting from a
change in the Prime Rate shall be subject to the provisions of this paragraph.

2.4. Computation Period.
Interest on the indebtedness evidenced by this Note shall be computed on the basis of a 360-day year and shall accrue on the actual number of days any principal balance hereof is outstanding.

2.5. LIBOR Election. If Maker elects to have the LIBOR Adjusted Rate apply, it shall advise Payee in writing by delivery to
Payee of the LIBOR Election Notice attached hereto as Exhibit A, of its election and the LIBOR Period and LIBOR Increment for which Maker desires said rate to apply not later than 10:00 a.m., Central Standard Time or Central
Daylight Time (as applicable), two (2) Business Days prior to the LIBOR Period Commencement Date. Any such election may be made only while no Event of Default is in existence and no event has occurred or condition exists which with notice
and/or lapse of time would constitute an Event of Default. After Maker has designated a LIBOR Increment to which the LIBOR Adjusted Rate shall apply, such rate shall apply to the LIBOR Increment for the duration of the LIBOR Period. If Maker elects
the LIBOR Adjusted Rate, but the applicable LIBOR Period will commence on a date which is not a Business Day, such LIBOR Period shall be deemed to commence on the next Business Day after it would otherwise commence, and any interest which accrues
hereunder in the interim shall accrue at the Applicable Rate. At any one time during the term hereof, no more than five (5) LIBOR Increments may be outstanding under this Note.

2.5.1 Failure of Election. Notwithstanding anything herein to the contrary, if the Maker elects the LIBOR Adjusted Rate to apply, but Payee would be unable for any reason to obtain funds or a quote for funds in the London
InterBank Market in the amount of the LIBOR Increment elected for the applicable LIBOR Period and LIBOR Period Commencement Date elected, interest on the outstanding principal balance of this Note shall accrue at the CB Floating Rate unless and
until an election, in accordance with the provisions hereof, of a new LIBOR Adjusted Rate, LIBOR Increment, LIBOR Period and LIBOR Period Commencement Date is made by Maker, and Payee is then able to obtain such funds or a quote for funds in the
London InterBank Market. In the absence of an effective election by Maker of the LIBOR Adjusted Rate in accordance with the above procedures prior to the expiration of the then current LIBOR Period with respect to any LIBOR Increment, interest on
such LIBOR Increment shall accrue at the CB Floating Rate, effective immediately upon the expiration of such LIBOR Period.

2.5.2 Illegality. Notwithstanding any other provision of this Note to the contrary, if it becomes unlawful for Payee to honor its obligation to allow all or a portion of the outstanding
principal balance hereof to accrue interest based on the LIBOR Rate, then Payee shall promptly notify Maker thereof and Payees obligation to allow interest to accrue based on the LIBOR Rate shall be suspended until such time as Payee may again
allow interest to accrue based upon the LIBOR Rate. If the obligation of Payee to allow interest to accrue based upon the LIBOR Rate is so suspended, all indebtedness evidenced hereby then accruing interest based upon the LIBOR Rate shall
automatically convert to interest based on the CB Floating Rate on the last days(s) of the then current LIBOR Period(s) for such indebtedness or on such earlier date as Payee may specify to Maker.



|3. | PAYMENTS.

3.4. Business
Days. If any payment of principal or interest on this Note shall become due and payable on a Saturday, Sunday or any other day on which Payee is not open for normal business, such payment shall be made on the next succeeding business day of
Payee. Any such extension of time for payment shall be included in computing interest which has accrued and shall be payable in connection with such payment.

3.5. Legal Tender. All amounts payable hereunder are payable in lawful money or legal tender of the United States of America.

3.6. Prepayments. Maker shall not have the right to prepay the Loan in part or in whole except as provided in
Section 2.1 of the Loan Agreement and, thereafter, as follows:

3.6.1 Maker shall have the
right prior to the Maturity Date, upon ten (10) days prior written notice and upon receipt of any required regulatory approval, to prepay all or any portion (except any portion constituting a LIBOR Increment during its applicable LIBOR
Period) of the principal balance owing hereunder from time to time; provided, however, that (a) if such prepayment is only a partial payment of the then outstanding principal balance hereof, such prepayment shall be accompanied by the payment
of all accrued but unpaid interest on the portion of the outstanding principal balance of the Note being so paid through the date the prepayment is made, and (b) for same day credit all monies shall be received at Payees office as
specified in Section 3.3 hereof on or before 12:00 noon, Central Standard Time or Central Daylight Time (as applicable). All monies received after this time shall be deemed received on the following day and shall continue to accrue
interest at the Applicable Rate to the date funds are deemed received.

3.6.2 Maker shall have the
right to prepay any LIBOR Increment only upon payment to Payee, at the time of such prepayment, of an amount equal to all costs, fees and penalties which would be incurred in the breaking of a LIBOR contract (whether then actually in existence or a
hypothetical contract similar to the typical LIBOR contracts then in existence) by Payee in connection with such prepayment, such amounts to include that sum which is equal to the excess of (i) the interest that would have been payable by Maker
for such LIBOR Increment for the remainder of the applicable LIBOR Period at the applicable LIBOR Rate had such prepayment not been made by Maker, over (ii) the interest to be earned on sums equal to the amount of such LIBOR Increment for the
remainder of the applicable LIBOR Period as invested by Payee in an interest bearing obligation of Payees selection, in its sole and absolute discretion. In addition, in any such event, the provisions of the immediately preceding sentence
(relating to the obligation of Maker to pay to Payee certain amounts in the event of the prepayment of a LIBOR Increment prior to the last day of the applicable LIBOR Period) shall apply with respect to any LIBOR Increment prepaid by Maker prior to
the last day of the applicable LIBOR Period as a result of the acceleration by Payee of the outstanding principal balance hereof

3.7. Late Charge. In addition to the payments otherwise specified herein, subject to the provisions of Section 5.4 hereof, if Maker fails, refuses or neglects to pay, in full, any installment or portion of the
indebtedness evidenced hereby, within ten (10) days after same shall be due and payable, then Maker shall be obligated to pay to Payee a late charge equal to five percent (5%) of the amount of such delinquent payment to compensate Payee
for Makers default and the additional costs and administrative efforts required by reason of such default; provided, however, Payee will apply any late charge fee collected from Maker to the amount of interest charged at the Default Rate which
covers the period for which such late charge was collected.

|4. | DEFAULT AND REMEDIES.
|-- | ---------------------

4.1. Default. An Event of Default shall occur hereunder if (i) Maker shall fail, refuse or neglect to pay, in full, any installment or portion of the indebtedness evidenced hereby, within ten
(10) days after the same shall become due and payable, whether at the due date thereof as stipulated herein, or upon acceleration (but without any grace period), or (ii) an Event of Default (as defined and used in any of the other Loan
Documents) shall occur under any of the other Loan Documents.

4.2. Remedies. If an Event of Default shall occur
under this Note or any of the Loan Documents (as herein defined), then Payee may, at its option, without notice or demand, declare the unpaid principal balance of, and the accrued but unpaid interest on, this Note immediately due and payable,

extended from time to time without notice and consent, (ii) to the acceptance of further collateral, and/or (iii) the release of any existing collateral for the payment of this Note, all without in any manner affecting their liability
under or with respect to this Note. No extension of time for the payment of this Note or any installment hereof shall affect the liability of Maker under this Note or any endorser or guarantor hereof even though the Maker or such endorser or
guarantor is not a party to such agreement.

4.4. No Waiver.Failure of Payee to exercise any of the options
granted herein to Payee upon the happening of one or more of the events giving rise to such options shall not constitute a waiver of the right to exercise the same or any other option at any subsequent time in respect to the same or any other event.
The acceptance by Payee of any payment hereunder that is less than payment in full of all amounts due and payable at the time of such payment shall not constitute a waiver of the right to exercise any of the options granted herein to Payee at that
time or at any subsequent time or nullify any prior exercise of any such option without the express written acknowledgment of the Payee.

4.5. Collection Costs. Maker, agrees to pay all reasonable costs of collection hereof when incurred, including reasonable attorneys fees, whether or not any legal action shall be
instituted to enforce this Note.

5.3. Governing Law. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND THE APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. THIS NOTE IS PERFORMABLE IN TARRANT COUNTY, TEXAS.Any action or proceeding under or in connection with this Note against Maker or any other
party ever liable for payment of any sums of money payable on this Note may be brought in any state court located in Fort Worth, Tarrant County, Texas, or any federal court in Tarrant County, Texas. Maker and each such other party hereby irrevocably
(i) submits to the nonexclusive jurisdiction of such courts, and (ii) waives any objection it may now or hereafter have as to the venue of any such action or proceeding brought in such court or that such court is an inconvenient forum.

5.4. Interest Limitation.It is expressly stipulated and agreed to be the intent of Maker and Payee at all
times to comply with the applicable Texas law governing the maximum rate or amount of interest payable on this Note or the indebtedness (Indebtedness) evidenced hereby or evidenced or secured by the other Loan Documents (or
applicable United States Federal law to the extent that it permits Payee to contract for, charge, take, reserve or receive a greater amount of interest than under Texas law). If the applicable law is ever 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, or Payees exercise of the option to accelerate the maturity of

this Note, or any prepayment by Maker results in Maker having paid or Payee having received any interest in excess of that permitted by applicable law, then it is Makers and Payees
express intent that all excess amounts theretofore collected by Payee be credited on the principal balance of this Note and all other Indebtedness (or, if this Note and all other Indebtedness have been or would thereby be paid in full, refunded to
Maker), and the provisions of this Note and the other Loan Documents immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply
with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder; provided, however, if this Note has been paid in full before the end of the stated term of this Note, then Maker and Payee
agree that Payee shall, with reasonable promptness after Payee discovers or is advised by Maker that interest was received in an amount in excess of the Maximum Lawful Rate, either refund such excess interest to Maker or credit such excess interest
against any other Indebtedness then owing by Maker to Payee. Maker hereby agrees that as a condition precedent to any claim seeking usury penalties against Payee, that Maker will provide written notice to Payee, advising Payee in reasonable detail
of the nature and amount of the violation, and Payee shall have sixty (60) days after receipt of such notice in which to correct such usury violation, if any, by either refunding such excess interest to Maker or crediting such excess interest
against any other indebtedness then owing by Maker to Payee. All sums contracted for, charged or received by Payee for the use, forbearance or detention of the Indebtedness shall, to the extent permitted by applicable law, be amortized or spread,
using the actuarial method, throughout the stated term of the Indebtedness until payment in full so that the rate or amount of interest on account of the Indebtedness does not exceed the Maximum Lawful Rate from time to time in effect and applicable
to the Indebtedness for so long as debt is outstanding. In no event shall the provisions of Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving triparty accounts) apply to the Indebtedness.
Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Payee 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. As used herein, the term Maximum Lawful Rate shall mean the maximum lawful rate of interest which may be contracted for, charged, taken, received or reserved by Payee in accordance with
the applicable laws of the State of Texas (or applicable United States Federal law to the extent that it permits Payee to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law), taking into account all
Charges (as herein defined) made in connection with the transaction evidenced by this Note and the other Loan Documents. As used herein, the term Charges shall mean all fees and charges, if any, contracted for, charged, received,
taken or reserved by Payee in connection with the transactions relating to this Note and the other Loan Documents or the Indebtedness, which are treated as interest under applicable law. To the extent that Payee is relying on the Texas Finance Code
to determine the Maximum Lawful Rate payable on the Indebtedness, Payee will utilize the weekly ceiling specified in Chapter 303 as the applicable ceiling, after taking into consideration all sums paid or agreed to be paid to Payee
outside the provisions of this Note for the use, forbearance or detention of the Indebtedness. To the extent United States federal law permits Payee to contract for, charge or receive a greater amount of interest, Payee will rely on United States
federal law instead of the Texas Finance Code, for the purpose of determining the Maximum Lawful Rate. Additionally, to the extent permitted by applicable law now or hereinafter in effect, Payee may, at its option and from time to time, implement
any other method of computing the Maximum Lawful Rate under the Texas Finance Code as supplemented by the Texas Credit Code, as amended, or under other applicable law by giving notice, if required, to Maker as provided by applicable law now or
hereafter in effect. Maker and Payee hereby agree that any and all suits alleging the contracting for, charging or receiving of usurious interest shall lie in Tarrant County, Texas, and each irrevocably waive the right to venue in any other county.
