Section 2.06. Subordination. 

(a) The Company, for itself, its successors and assigns, covenants and agrees, and each Holder of Notes by the Holder’s acceptance
thereof, likewise covenants and agrees, that the payment of the principal of and interest on each and all of the Notes is and will be expressly subordinated in right of payment to the prior payment in full of all Senior Indebtedness, subject to
clause (j) of this Section 2.06, to the extent and in the manner described in this Section 2.06 and Section 1501 of the Base Indenture. 

(b) Upon any distribution of assets of the Company upon any termination, winding up, liquidation or reorganization of the Company, whether in
bankruptcy, insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or otherwise (subject to the power of a court of competent
jurisdiction to make other equitable provision reflecting the rights conferred upon the Senior Indebtedness and the holders thereof with respect to the Notes and the Holders thereof by a lawful plan of reorganization under applicable bankruptcy
law): 
 (i) the holders of all Senior Indebtedness shall first be entitled to receive payment in full in accordance with the
terms of such Senior Indebtedness of the principal thereof, premium, if any, and the interest due thereon (including interest accruing subsequent to the commencement of any proceeding for the bankruptcy or reorganization of the Company under any
applicable bankruptcy, insolvency or similar law now or hereafter in effect) before the Holders of the Notes are entitled to receive any payment upon the principal of or interest on indebtedness evidenced by the Notes; 

(ii) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to
which the Holders of the Notes would be entitled except for the provisions of Section 1501 of the Base Indenture and this Section 2.06, including any such payment or distribution that may be payable or deliverable by
reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Notes, shall be paid by the liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior
Indebtedness may have been issued, in accordance with the priorities then existing among holders of Senior Indebtedness for payment of the aggregate amounts remaining unpaid on account of the principal, premium, if any, and interest (including
interest accruing subsequent to the commencement of any proceeding for the bankruptcy or reorganization of the Company under any applicable bankruptcy, insolvency or similar law now or hereafter in effect) on the Senior Indebtedness held or
represented by each, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; it being understood that if
the Holders of the Notes shall fail to file a proper claim in the form required by any proceeding referred to in this subparagraph (ii) prior to 30 days before the expiration of the time to file such claim or claims, then the holders of
Senior Indebtedness are hereby authorized to file an appropriate claim or claims for and on behalf of the Holders of the Notes, in the form required in any such proceeding; and 

(iii) in the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, including any such payment or distribution that may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinate to the payment of the Notes shall
be received by the Trustee or Holders of the 

  
 6 

 
Notes before all Senior Indebtedness is paid in full, such payment or distribution shall be paid over to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or
other Person making payment of assets of the Company for all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness. 
 Subject to the payment in full of all Senior Indebtedness, the Holders of the Notes shall be subrogated to the
rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal of and interest on the Notes shall be paid in full and no such
payments or distributions to holders of such Senior Indebtedness to which the Holders of the Notes would be entitled except for the provisions hereof of cash, property or securities otherwise distributable to the holders of Senior Indebtedness
shall, as between the Company, its creditors, other than the holders of Senior Indebtedness, and the Holders of the Notes, be deemed to be a payment by the Company to or on account of the Senior Indebtedness. It is understood that the provisions of
this Section 2.06 are intended solely for the purpose of defining the relative rights of the Holders of the Notes, on the one hand, and the holders of Senior Indebtedness, on the other hand, and, in the case of clause
(j) of this Section 2.06, the holders of Existing Company Subordinated Indebtedness. Nothing contained in this Section 2.06 or elsewhere in the Base Indenture, this Second Supplemental
Indenture or any supplemental indenture issued pursuant to Section 301 or Article Nine of the Base Indenture or in the Notes is intended to or shall impair, as between the Company, its creditors, other than the holders of Senior Indebtedness,
and the Holders of the Notes, the obligation of the Company, which is unconditional and absolute, to pay to the Holders of the Notes the principal of and interest on the Notes as and when the same shall become due and payable in accordance with
their terms or to affect the relative rights of the Holders of the Notes and creditors of the Company, other than the holders of the Senior Indebtedness, nor, except as otherwise expressly provided in the Base Indenture, this Second Supplemental
Indenture and the Notes with respect to the limitation on the rights of the Trustee and the Holders of Notes, to accelerate the maturity of the Notes and pursue remedies upon such an acceleration, shall anything herein or in the Notes prevent the
Trustee or the Holder of any Notes from exercising all remedies otherwise permitted by applicable law upon any Event of Default under the Indenture occurring, subject to the rights, if any, under this Section 2.06 of the
holders of Senior Indebtedness, in respect of cash, property or securities of the Company received upon the exercise of any such remedy. Upon any payment or distribution of assets of the Company referred to in this
Section 2.06, the Trustee and the Holders of the Notes shall be entitled to rely upon any order or decree of a court of competent jurisdiction in which such termination, winding up, liquidation or reorganization proceeding
is pending or upon a certificate of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of the Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the amount hereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Section 2.06. In the absence of any such liquidating trustee, agent or other Person, the Trustee shall be entitled to rely upon a written notice by a Person representing itself to be a holder of Senior Indebtedness (or a
trustee or representative on behalf of such holder) as evidence that such Person is a holder of Senior Indebtedness (or is such a trustee or representative). If the Trustee determines, in good faith, that further evidence is required with respect to
the right of any Person, as a holder of Senior Indebtedness, to participate in any payment or distribution pursuant to this Section 2.06, the Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, as to the extent to which such Person is entitled to participation in such payment or distribution, and as to other facts pertinent to the rights of such Person
under this Section 2.06, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Section 2.06, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Section 2.06 against the
Trustee. The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness by reason of the execution of the Base Indenture, this Second Supplemental Indenture, or any other supplemental indenture entered into
pursuant to Section 301 or Article Nine of the Base Indenture, and shall not be liable to any such holders if it shall mistakenly pay over or distribute to or on behalf of Holders of the Notes or the Company moneys or assets to which any
holders of Senior Indebtedness shall be entitled by virtue of this Section 2.06. 

  
 7 

 (c) In the event and during the continuation of any default in the payment of principal of, or
premium, if any, or interest on, any Senior Indebtedness, beyond any applicable period of grace, or if any event of default with respect to any Senior Indebtedness shall have occurred and be continuing, or would occur as a result of the payment
referred to hereinafter, permitting the holders of such Senior Indebtedness (or a trustee on behalf of the holders thereof) to accelerate the maturity thereof, then, unless and until such default or event of default shall have been cured or waived
or shall have ceased to exist, no payment or principal of or interest on the Notes, or in respect of any retirement, purchase or other acquisition of any of the Notes, shall be made by the Company. 

(d) Nothing contained in the Base Indenture, this Second Supplemental Indenture, any other supplemental indenture entered into pursuant to
Section 301 or Article Nine of the Base Indenture, or in any of the Notes shall: (i) impair, as between the Company and Holders of the Notes, the obligations of the Company, to make, or prevent the Company from making, at any time
except as provided in clauses (b), (c), or (j) of this Section 2.06, payments of principal of, or interest (including interest accruing subsequent to the commencement of any proceeding for the
bankruptcy or reorganization of the Company under any applicable bankruptcy, insolvency, or similar law now or hereafter in effect) on, the Notes, as and when the same shall become due and payable in accordance with the terms of the Notes;
(ii) affect the relative rights of the Holders of the Notes and creditors of the Company other than the holders of the Senior Indebtedness; (iii) except as otherwise expressly provided in the Base Indenture, this Second Supplemental
Indenture and the Notes with respect to the limitation on the rights of the Trustee and the Holders of Notes, to accelerate the maturity of the Notes and pursue remedies upon such an acceleration, prevent the Holder of any Notes or the Trustee from
exercising all remedies otherwise permitted by applicable law upon default thereunder, subject to the rights, if any, under this Section 2.06 of the holders of Senior Indebtedness in respect of cash, property or securities
of the Company received upon the exercise of such remedy; or (iv) prevent the application by the Trustee or any Paying Agent of any moneys deposited with it hereunder to the payment of or on account of the principal of, or interest on, the
Notes or prevent the receipt by the Trustee or any Paying Agent of such moneys, if, prior to the third Business Day prior to such deposit, the Trustee or such Paying Agent did not have written notice of any event prohibiting the making of such
deposit by the Company. 
 (e) Each Holder by his acceptance of any Notes authorizes and expressly directs the Trustee on such Holder’s
behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in the Indenture, and appoints the Trustee such Holder’s
attorney-in-fact for such purposes, including, in the event of any termination, winding up, liquidation or reorganization of the Company (whether in bankruptcy,
insolvency, receivership, reorganization or similar proceedings or upon an assignment for the benefit of creditors by the Company, a marshalling of the assets and liabilities of the Company or otherwise) tending toward the liquidation of the
property and assets of the Company, the filing of a claim for the unpaid balance of the Notes in the form required in those proceedings. 

The Company shall give prompt written notice to the Trustee of any fact known to the Company that would prohibit the Company from making any
payment to or by the Trustee in respect of the Notes pursuant to the provisions of this Section 2.06 or Article Fifteen of the Base Indenture. The Trustee shall not be charged with the knowledge of the existence of any
default or event of default with respect to any Senior Indebtedness or of any other facts that would prohibit the making of any payment to or by the Trustee unless and until the Trustee shall have received notice in writing at its Corporate Trust
Office to that effect signed by an Officer of the Company, or by a holder of Senior Indebtedness or a trustee or agent thereof; and prior to the receipt of any such written notice, the Trustee shall, subject to Article Six of the Indenture, be
entitled to assume that no such facts exist; provided that, if the Trustee shall not have received the notice provided for in this Section 2.06 at least two Business Days prior to the date upon which, by the terms of the
Indenture, any monies shall become payable for any purpose (including, without limitation, the payment of the principal of or interest on any Note), then, notwithstanding anything herein to the contrary, the Trustee shall have full power and
authority to receive any monies from the Company and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary that may be received by it on or after such prior date except for an
acceleration of the Notes prior to such application. The foregoing shall not apply if the Paying Agent is the Company. The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself or itself to be a
holder of any Senior Indebtedness (or a trustee on behalf of, or agent of, such holder) to establish that such notice has been given by a holder of such Senior Indebtedness or a trustee or agent on behalf of any such holder. 

  
 8 

 In the event that the Trustee determines in good faith that any evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Section 2.06 or Article Fifteen of the Base Indenture, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to
the rights of such Person under this Section 2.06 or Article Fifteen of the Base Indenture and, if such evidence is not furnished to the Trustee, the Trustee may defer any payment to such Person pending such evidence
being furnished to the Trustee or a judicial determination that such Person has the right to receive such payment. 
 (f) Notwithstanding
the provisions of this Section 2.06 or any other provisions of the Base Indenture, this Second Supplemental Indenture or any other supplemental indenture issued pursuant to Section 301 or Article Nine of the Base
Indenture, neither the Trustee nor any Paying Agent shall be charged with knowledge of the existence of any Senior Indebtedness or of any event that would prohibit the making of any payment or moneys to or by the Trustee or such Paying Agent, unless
and until a Responsible Officer of the Trustee or such Paying Agent shall have received written notice thereof from the Company or from the holder of any Senior Indebtedness or from the representative of any such holder. 

(g) The Trustee shall be entitled to all of the rights set forth in this Section 2.06 in respect of any Senior
Indebtedness at any time held by it in its individual capacity to the same extent as any other holder of such Senior Indebtedness, and nothing in the Base Indenture, this Second Supplemental Indenture or any other supplemental indenture issued
pursuant to Section 301 or Article Nine of the Base Indenture shall be construed to deprive the Trustee of any of its rights as such holder. 

(h) The failure to make a payment pursuant to the Notes by reason of any provision in this Section 2.06 shall not be
construed as preventing the occurrence of a Default or any Event of Default. 
 (i) Nothing contained in this
Section 2.06 shall apply to the claims of, or payments to, the Trustee under or pursuant to Section 607 of the Base Indenture. 

(j) Subject to the provisions of this clause (j) of Section 2.06 and to any provisions established or
determined with respect to Securities of any Series pursuant to Section 301 of the Base Indenture, the Notes shall rank pari passu in right of payment with the Existing Company Subordinated Indebtedness. Upon the occurrence of any of the events
specified in clause (b) of this Section 2.06, the provisions of that clause and the corresponding provisions of each indenture or other instrument or document establishing or governing the terms of any Existing
Company Subordinated Indebtedness shall be given effect on a pro rata basis to determine the amount of cash, property or securities that may be payable or deliverable as between the holders of Senior Indebtedness, on the one hand, and the Holders of
the Notes and holders of Existing Company Subordinated Indebtedness, on the other hand. 
 (k) The subordination provisions in this
Section 2.06 or Article Fifteen of the Base Indenture do not apply to amounts due to the Trustee pursuant to other sections of the Indenture, including Section 607 of the Base Indenture. 

Section 2.07. Events of Default; Acceleration. All of the Events of Default set forth in clauses (1), (2), (4), (5) and
(6) of Section 501 of the Base Indenture will apply with respect to the Notes. Notwithstanding the foregoing, because the Company will treat the Notes as Tier 2 capital (or its then equivalent if the Company were subject to such capital
requirement) for purposes of capital adequacy guidelines of the Federal Reserve Board as then in effect and applicable to the Company, upon the occurrence of an Event of Default other than an Event of Default set forth in clause (5) or
(6) of Section 501 of the Base Indenture, neither the Trustee nor the holders of the Notes may accelerate the Maturity of the Notes and make the principal of, and any accrued and unpaid interest on, the Notes, immediately due and payable.

 Section 2.08. No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund. 

Section 2.09. No Conversion or Exchange Rights. The Notes shall not be convertible into or exchangeable for any equity securities,
other securities or other assets of the Company or any Subsidiary. 

  
 9 

 Section 2.10. No Defeasance or Covenant Defeasance. Sections 1202 and 1203 of
the Base Indenture shall not be applicable to the Notes. 
 ARTICLE 3 

REDEMPTION OF THE NOTES 

Section 3.01. Optional Redemption. The Notes shall not be redeemable prior to December 31, 2022, except as provided in
Section 3.02. The Notes shall be redeemable, in whole or in part, at the option of the Company beginning on December 31, 2022, and on any Interest Payment Date thereafter, at a redemption price equal to 100% of the
principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date, and any such redemption may be subject to the satisfaction of one or more conditions precedent set forth in the applicable notice
of redemption (an “Optional Redemption”). No such Optional Redemption of the Notes by the Company prior to the Maturity Date shall be made without the prior approval of the Federal Reserve Board if such prior approval is or will be
required at the scheduled Redemption Date in order for the Notes to qualify as Tier 2 capital of the Company under the rules and guidelines of the Federal Reserve Board. The Notes are not subject to repayment at the option of the Holders. 

Section 3.02. Redemption of Special Events. Other than in the case of an Optional Redemption, the Notes may not be redeemed,
called or repurchased by the Company prior to the Maturity Date, except that the Company may also, at its option, redeem the Notes at any time before the Maturity Date in whole, but not in part, at any time within 90 days of the occurrence of a Tax
Event, a Tier 2 Capital Event or if the Company is required to register as an investment company pursuant to the Investment Company Act of 1940 (15 U.S.C. 80a-1 et seq.). Any such redemption will be at a
redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date, and any such redemption may be subject to the satisfaction of one or more conditions
precedent set forth in the applicable notice of redemption. No such redemption of the Notes by the Company prior to the Maturity Date shall be made without the prior approval of the Federal Reserve Board if such prior approval is or will be required
at the scheduled Redemption Date in order for the Notes to qualify as Tier 2 capital of the Company under the rules and guidelines of the Federal Reserve Board. 

Section 3.03. Notice to Trustee. If the Company elects to redeem the Notes pursuant to the optional redemption provisions of
Section 3.01 or Section 3.02 of this Second Supplemental Indenture, at least 45 days prior to the Redemption Date (unless a shorter notice shall be agreed to in writing by the Trustee) but not more
than 60 days before the Redemption Date, the Company shall furnish to the Trustee a Company Officers’ Certificate setting forth (i) the applicable section of this Indenture pursuant to which the redemption shall occur, (ii) the
Redemption Date, (iii) the principal amount of Notes to be redeemed, (iv) the redemption price and (v) a Company Board Resolution. 

Section 3.04. Partial Redemption. In the case of a redemption pursuant to Section 3.01, if less than all
of the Notes are to be redeemed and the Notes are global Securities, the Trustee shall select the Notes to be redeemed equally, by lot or in a manner the Trustee deems fair and appropriate. The Trustee shall promptly notify in writing the Company of
the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in minimum amounts of $1,000 or integral multiples of $1,000
in excess thereof; no Notes of a principal amount of $1,000 or less shall be redeemed in part, except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not equal to $1,000 or
an integral multiple of $1,000 in excess thereof, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

Section 3.05. Notice to Holders. In the case of any redemption, at least 30 days but no more than 60 days before the Redemption
Date, the Company shall send in accordance with the applicable procedures of the Depositary, or if the Notes are not then global Securities the Company shall mail, or cause to be mailed, a notice of redemption by first-class mail to each Holder of
Notes to be redeemed at such Holder’s registered address appearing on the register. The notice shall identify the Notes to be redeemed (including the CUSIP and/or ISIN numbers thereof, if any) and shall state: 

(a) the Redemption Date; 

  
 10 

 (b) the principal amount of the Notes that are being redeemed; 

(c) each Place of Payment; 
 (d)
the redemption price and accrued interest to the Redemption Date that is payable pursuant to Section 1102 of the Base Indenture; 
 (e)
if fewer than all outstanding Notes are to be redeemed, the portion of the principal amount of such Notes to be redeemed and that, after the Redemption Date and upon surrender of such Notes, if applicable, a new Note or Notes in principal amount
equal to the unredeemed portion will be issued; 
 (f) the name and address of the Paying Agent; 

(g) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(h) that unless the Company defaults in making the redemption payment, interest on Notes called for redemption ceases to accrue on and after
the Redemption Date; 
 (i) if such notice is conditioned upon the satisfaction of one or more conditions precedent, the nature of such
conditions precedent; 
 (j) the applicable section of this Indenture pursuant to which the Notes called for redemption are being redeemed;
and 
 (k) that no representation is made as to the correctness or accuracy of the CUSIP and/or ISIN numbers, if any, listed in such notice
or printed on the Notes. 
 The Company may state in the notice of redemption that payment of the redemption price and performance of its
obligations with respect to redemption or purchase may be performed by another Person. 
 At the Company’s request, the Trustee shall
give the notice of redemption in the Company’s name and at its expense; provided, that the Company shall have delivered to the Trustee, at least 45 days prior to the Redemption Date, a Company Officers’ Certificate requesting that the
Trustee give such notice and attaching a copy of such notice, which shall set forth the information to be stated in such notice as provided in this Article 3. If any condition precedent to a redemption has not been
satisfied, the Company will provide written notice to the Trustee not less than two Business Days prior to the Redemption Date that such condition precedent has not been satisfied, that the notice of redemption is rescinded or delayed and that the
redemption subject to the satisfaction of such condition precedent shall not occur or shall be delayed. The Trustee shall promptly send a copy of such notice to the Holders of the Notes.

INDEPENDENT BANK GROUP, INC. 

5.00% FIXED-TO-FLOATING RATE SUBORDINATED NOTES DUE

 This Note is one of a duly authorized issue of Securities of the Company of a Series designated as the

of $30,000,000 on December 19, 2017. Such Series of Securities has been established pursuant to, and is one of an unsecured indefinite number of Series of subordinated debt securities of the Company issued or issuable under and pursuant to, the
Subordinated Debt Indenture (the “Base Indenture”), dated as of June 25, 2014, between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee,” which term includes any
successor trustee), as supplemented and amended by the Second Supplemental Indenture, between the Company and the Trustee, dated as of December 19, 2017 (the “Second Supplemental Indenture” and the Base Indenture as
supplemented and amended by the Second Supplemental Indenture, the “Indenture”), to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of
rights, duties and immunities thereunder of the Company, the Trustee and the Persons in whose names Notes are registered on the Security Register from time to time and of the terms upon which the Notes are, and are to be, authenticated and
delivered. This Note shall not be valid until the Trustee manually signs the certificate of authentication on this Note. The terms, conditions and provisions of the Notes are those stated in the Indenture, those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended, and those set forth in this Note. To the extent that the terms, conditions and provisions of this Note modify, supplement or are inconsistent with those of the Indenture, then the terms,
conditions and other provisions of this Note shall govern to the extent such terms, conditions and other provisions of this Note are not inconsistent with the terms, conditions and provisions made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended. 
 All capitalized terms used in this Note and not defined herein that are defined in the Base Indenture
or the Second Supplemental Indenture shall have the meanings assigned to them in the Base Indenture or the Second Supplemental Indenture. If any capitalized term used in this Note and defined herein is also defined in the Base Indenture or the
Second Supplemental Indenture, in the event of any conflict in the meanings ascribed to such capitalized term, the definition of the capitalized term in this Note shall control. 

The indebtedness of the Company evidenced by the Notes, including the principal thereof and interest thereon, is, to the extent and in the
manner set forth in the Second Supplemental Indenture, subordinate and junior in right of payment to obligations of the Company constituting the Senior Indebtedness (as defined in the Indenture) on the terms and subject to the terms and conditions
as provided and set forth in Section 2.06 of the Second Supplemental Indenture and shall rank pari passu in right of payment with all other Notes and with all other unsecured subordinated indebtedness of the Company issued under the Indenture
and not by its terms subordinate and junior in right of payment to the promissory notes, bonds, debentures or other evidences of indebtedness of types that include the Notes. Each Holder of this Security, by the acceptance hereof, agrees to and
shall be bound by such provisions of the Indenture and authorizes and directs the Trustee on his behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided. 

Interest accruing under this Note during the Fixed Rate Period will be computed on the basis of a
360-day year consisting of twelve 30-day months and interest accruing under this Note during the Floating Rate Period will be computed on the basis of the actual number
of days in a Floating Rate Interest Period and a 360-day year. The Company shall pay interest on overdue principal from time to time on demand at the rate borne by the Notes and on overdue installments of
interest (without regard to any applicable grace periods) to the extent lawful. 
 The term “three-month LIBOR” means, as
determined by the Calculation Agent (as defined below) on the second London Banking Day immediately preceding the commencement of the applicable Floating Rate Interest Period (the “determination date”) and provided to the trustee in
writing, the offered rate for deposits in U.S. dollars having a maturity of three months that appears on the Designated LIBOR Page as of approximately 11:00 a.m., London time, on such determination date. If such rate does not appear on the
Designated LIBOR Page (as defined below) at such time, or the Designated LIBOR Page is not available on such date, the Calculation Agent shall obtain such rate from Bloomberg L.P.’s page “BBAM” (or any successor or replacement page).
If the Calculation Agent determines that such rate has been discontinued, then it shall determine in its sole discretion whether to use a substitute or successor base rate 

  
 A-6 

 
that is most comparable to such rate, provided that if the Calculation Agent determines there is an industry accepted successor base rate, the Calculation Agent shall use such successor base
rate, and if the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may also implement changes to the business day convention, any business day
definition, the determination date and any method for obtaining the substitute or successor base rate if such rate is unavailable on the relevant business day, in a manner that is consistent with industry accepted practices for such substitute or
successor base rate. If the Calculation Agent determines that such rate has been discontinued, but the Calculation Agent does not determine to use a substitute or successor base rate as provided above, then the Calculation Agent will request the
principal London office of each of four major reference banks in the London interbank market, selected by the Calculation Agent, to provide such bank’s offered quotation to prime banks in the London interbank market for deposits in U.S. dollars
with a term of three months as of 11:00 a.m., London time, on such determination date and in a principal amount equal to an amount that, in the judgment of the Calculation Agent, is representative for a single transaction in U.S. dollars in the
relevant market at the relevant time (a “representative amount”). If at least two such quotations are so provided, three-month LIBOR for such Floating Rate Interest Period will be the arithmetic mean of such quotations. If fewer
than two such quotations are provided, the Calculation Agent will request each of three major banks in the City of New York to provide such bank’s rate for loans in U.S. dollars to leading European banks with a term of three months as of
approximately 11:00 a.m., the City of New York time, on such determination date and in a representative amount. If at least two such rates are so provided, three-month LIBOR for such Floating Rate Period will be the arithmetic mean of such
quotations. If fewer than two such rates are so provided, then three-month LIBOR for such Floating Rate Interest Period will be set to equal the three-month LIBOR for the then current Floating Rate Interest Period or, in the case of the first
Floating Rate Interest Period, 2.17% (resulting in a 5.00% interest rate on the notes for such first Floating Rate Interest Period). 
 The
term “Designated LIBOR Page” means the display on Reuters or any successor service, on page LIBOR01 or on any other page as may replace that page on the service, for the purpose of displaying the London interbank rates of U.S.
dollars. 
 If any Interest Payment Date, including the Maturity Date, falls on a day that is not a Business Day, (i), in the case of a
Fixed Rate Interest Payment Date, the related payment will be made on the next succeeding Business Day with the same force and effect as if made on the day such payment was due, and no interest will accrue on the amount so payable for the period
from and after such Interest Payment Date or the Maturity Date, as the case may be, to the next succeeding Business Day, and (ii) in the case of a Floating Rate Interest Payment Date, then payment of interest payable on such Floating Rate
Interest Payment Date will be postponed to the next succeeding day that is a Business Day, unless such day falls in the next succeeding calendar month, in which case, such Floating Rate Interest Payment Date will be accelerated to the immediately
preceding day that is a Business Day, and in each such case, the amounts payable on such Business Day will include interest accrued to, but excluding, such Floating Rate Interest Payment Date as so adjusted. Interest will be computed on the basis of
a 360-day year consisting of twelve 30-day months to but excluding December 31, 2022, and, thereafter, interest will be computed on the basis of the actual number
of days in a Floating Rate Interest Period and a 360-day year to but excluding December 31, 2027. All percentages used in or resulting from any calculation of three-month LIBOR shall be rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. 
 The Calculation
Agent’s determination of the applicable interest rate and its calculation of the amount of interest for any Floating Rate Interest Period shall be final and binding in the absence of manifest error. 

On or before the determination date for the first Floating Rate Interest Period, the Company will appoint a bank, trust company, investment
banking firm or other financial institution to serve as the calculation agent (the “Calculation Agent”), which appointment shall be made on such terms and conditions, and the Calculation Agent shall have such duties,
responsibilities, and obligations with respect to the Notes as the Company shall determine, provided that such terms, conditions, duties, responsibilities, and obligations shall be consistent with the terms and conditions of the Indenture and this
Note and shall be as necessary to provide for the calculation of three-month LIBOR for each Floating Rate Interest Period and the calculation of the rate at which interest will accrue under the Notes for each Floating Rate Interest Period. The
Calculation Agent so appointed by the Company in accordance with the terms and conditions of the Indenture, or in the event the Company does not engage a third party to act as the Calculation Agent on or before the determination date for the first
Floating Rate Interest Period, the Company (the “Initial Calculation Agent”) shall serve as the Calculation Agent hereunder unless and until a successor Calculation Agent is appointed by the Company. The Company shall appoint a
bank, trust company, investment banking firm or other financial institution 

  
 A-7 

 
to act as the successor Calculation Agent to the Initial Calculation Agent, or any of the Initial Calculation Agent’s successors in that capacity, in the event that: (a) any acting
Calculation Agent is unable or unwilling to act as the calculation agent hereunder; (b) any acting Calculation Agent fails to establish the floating interest rate for any Interest Period; or (c) the Company proposes to remove the
Calculation Agent. The Calculation Agent’s determination of three-month LIBOR and the interest rate at which interest will accrue during, and its calculation of the amount of accrued interest for, any Floating Rate Interest Period will, in the
absence of manifest error, be final and conclusive for all purposes and binding on the Holders of the Notes. The Calculation Agent shall promptly notify the Trustee and the Company of each determination of the interest rate applicable to the Notes,
and for each Floating Rate Interest Period, the amount of interest expected to accrue for such Floating Rate Interest Period and the Floating Rate Interest Payment Date related to such Floating Rate Interest Period as soon as such information
becomes available. The Calculation Agent shall make such information available to the Holder of this Note upon request. Unless otherwise specified herein, all percentages resulting from any calculation of the rate of interest on this Note will be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%, and all U.S. dollar amounts used in or resulting from such calculation will be rounded to the nearest cent (with one-half cent being rounded upward). 
 The Company shall pay interest on the Notes (except defaulted
interest) to the Persons who are the registered Holders at the close of business (whether or not a Business Day) on the Record Date immediately preceding the applicable Interest Payment Date notwithstanding any transfer or exchange of such Note
subsequent to such Record Date and prior to such Interest Payment Date. Holders must surrender Notes to the Trustee to collect principal payments. 

The Notes are intended to be treated as Tier 2 capital (or its then equivalent if the Company were subject to such capital requirement)
for purposes of capital adequacy guidelines of the Board of Governors of the Federal Reserve System (or any successor regulatory authority with jurisdiction over bank holding companies) (the “Federal Reserve Board”) as then in
effect and applicable to the Company. If an Event of Default with respect to Notes shall occur and be continuing, the principal and interest owed on the Notes shall only become due and payable in accordance with the terms and conditions set forth in
Article Five of the Base Indenture and Section 2.07 of the Second Supplemental Indenture. Accordingly, the holder of this Note has no right to accelerate the maturity of this Note in the event the Company fails to pay interest on any of
the Notes, fails to perform any other obligations under the Notes or in the Indenture that are applicable to the Notes. 
 The Company
may, at its option, redeem the Notes, in whole or in part, on any Floating Rate Interest Payment Date, beginning with the Floating Rate Interest Payment Date on December 31, 2022, and the Company may also, at its option, redeem the Notes, in
whole, but not in part, at any time before the Maturity Date within 90 days after the occurrence of a Tier 2 Capital Event or a Tax Event or if the Company is required to register as an investment company pursuant to the Investment Company Act
of 1940 (15 U.S.C. 80a-1 et seq.) (any such date on which Notes are to be so redeemed, a “Redemption Date”), in each case, at a redemption price equal to 100% of the principal amount of the
Notes to be redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date. On and after the Redemption Date, unless the Company shall fail to deposit the redemption price and accrued interest on the Notes called for redemption
that are payable on such Redemption Date as required by Section 1105 of the Indenture, interest shall cease to accrue on the Notes called for redemption. The provisions of Article Eleven of the Base Indenture and Article 3 of the Second
Supplemental Indenture shall apply to the redemption of any Notes by the Company. 
 No such redemption of the Notes by the Company prior to
the Maturity Date shall be made without the prior approval of the Federal Reserve Board if such prior approval is or will be required at the scheduled Redemption Date in order for the Notes to qualify as Tier 2 capital of the Company under the
rules and guidelines of the Board of Governors of the Federal Reserve System. 
 The Notes of this Series are not entitled to the benefit of
any sinking fund. The Notes are not convertible into or exchangeable for any of the equity securities, other securities or assets of the Company or any Subsidiary. 

The Base Indenture provisions relating to defeasance and covenant defeasance in Sections 1202 and 1203 of the Base Indenture shall not be
applicable to the Notes. 

  
 A-8 

 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the holders of the Notes at any time by the Company and the Trustee with the consent of the holders of a majority in principal amount of the Notes of each series (each
series voting as a class) affected thereby and at the time Outstanding. The Indenture also contains provisions permitting the holders of specified percentages in principal amount of the Notes of a series at the time Outstanding, on behalf of the
holders of all Notes of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of
this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security
Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this 2027 Series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes of this 2027 Series are issuable only
in fully registered form without coupons, in denominations of $1,000 and any integral multiple of $1,000 in excess of $1,000. 
 The Company
and the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary. 
 If funds for the payment of principal or interest remain unclaimed for two years, the
Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and interest (if any) on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

No recourse for the payment of the principal of or interest on any Note, or for any claim based thereon or otherwise in respect thereof, shall
be had against any shareholder, director, officer, employee or agent, member or incorporator, as such, past, present or future, of the Company, or of any successor Person to the Company, it being expressly understood that all such liability is
hereby expressly waived and released as a condition of, and as a consideration for, the issuance of the Notes. 
 [NOTE: THE PROVISIONS
BELOW THAT APPEAR IN BRACKETS WILL BE INSERTED INTO ANY GLOBAL NOTE REPRESENTING NOTES.] [This Security is a global note, represented by one or more permanent global certificates registered in the name of the nominee of The Depositary Trust Company
(each a “Global Note” and collectively, the “Global Notes”). Accordingly, unless and until it is exchanged in whole or in part for individual certificates evidencing the Notes represented hereby, this Security may
not be transferred except as a whole by The Depositary Trust Company (the “Depositary”) to a nominee of such Depositary or by a nominee of such Depositary or by the Depositary or any nominee to a successor Depositary or any nominee
of such successor. Ownership of beneficial interests in this Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the applicable Depositary or its nominee (with respect to interest of
Persons that have accounts with the Depositary (“Participants”) and the records of Participants (with respect to interests of Persons other than Participants)). Beneficial interests in Notes owned by Persons that hold through
Participants will be evidenced only by, and transfers of such beneficial interests with such Participants will be effected only through, records maintained by such Participants. Except as provided below, owners of beneficial interests in this
Security will not be entitled to have any individual certificates and will not be considered the owners or Holders thereof under the Indenture. 

Except in the limited circumstances set forth in Section 305 of the Base Indenture, Participants and owners of beneficial interests in
the Global Notes will not be entitled to receive Securities in definitive form and will not be considered Holders of Notes. Neither the Company nor the principal Paying Agent will be liable for any delay by the Depositary, its nominee or any direct
or indirect participant in identifying the beneficial owners of the related Notes. The Company and the principal payment agent may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all
purposes, including with respect to the registration and delivery, and the respective principal amounts, of the Notes to be issued. 

  
 A-9 

 Except as provided in Section 305 of the Base Indenture, beneficial owners of Global
Notes will not be entitled to receive physical delivery of Notes in definitive form and no Global Note will be exchangeable except for another Global Note of like denomination and tenor to be registered in the name of the Depositary or its nominee.
Accordingly, each Person owning a beneficial interest in a Global Note must rely on the procedures of the Depositary and, if such Person is not a Participant, on the procedures of the Participant through which such Person owns its interest, to
exercise any rights of a Holder under the Notes. 
 The laws of some jurisdictions may require that purchasers of securities take
physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the Notes represented by a Global Note to those Persons may be limited. In addition, because the Depositary can act only on behalf of its
Participants, who in turn act on behalf of Persons who hold interests through Participants, the ability of a Person having an interest in Notes represented by a Global Note to pledge or transfer such interest to Persons that do not participate in
the Depositary’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest. None of the Company, the Trustee, the Paying Agent and the Security
Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of Notes by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to the Notes.]

 Wells Fargo Bank, National Association will act as the Company’s principal Paying Agent with respect to the Notes through its
offices presently located at 1445 Ross Avenue, Suite 4300, Dallas, Texas 75202. The Company may at any time rescind the designation of a Paying Agent, appoint a successor Paying Agent, or approve a change in the office through which any Paying Agent
acts. 
 Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN
ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused the CUSIP
number for the Series of Securities of which the Notes are a part to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be
placed only on the other identification numbers printed hereon. 
 Notices to the Holders of registered Notes will be mailed to such Holders
at their respective addresses in the Security Register will be deemed to have been given on the fourth weekday (being a day other than Saturday or Sunday) after the date of mailing. The Indenture contains provisions setting forth certain conditions
to the institution of proceedings by the Holders of Notes with respect to the Indenture or for any remedy under the Indenture. 
 THIS
NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF TEXAS, AND FOR ALL PURPOSES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SAID STATE.

allow the PURCHASER and its authorized representatives to access to the management, personnel, properties and records, and

such party and the Person from whom consent is required as a condition to obtaining such consent. The ACQUIRED COMPANY will comply
with its obligations under this Agreement that are intended to be performed prior to the Execution Date.

 

7.
CONFIDENTIALITY

 

7.1
Confidential Information. The ACQUIRED COMPANY, SELLING MEMBER, and the PURCHASER each agree that all of the ACQUIRED COMPANY’s

research and development, market studies and business plans, historical financial statements, financial projections and budgets,
historical and projected sales, capital spending budgets and plans, contract terms, customer and vendor terms, employee information,
and any information that is marked “confidential” or in some comparable manner, whether or not reduced to writing,
in each case of or concerning the ACQUIRED COMPANY (the “Confidential Information”), immediately prior to the Execution,
is the ACQUIRED COMPANY’s sole, exclusive and valuable proprietary information and property, that such Confidential Information
derives independent economic value from not being readily known or ascertainable by proper means by others who can obtain economic
value from its disclosure or use, that reasonable efforts have been made by the ACQUIRED COMPANY prior to Execution to maintain
the confidentiality of such Confidential Information, and that upon the Execution such Confidential Information will become the
sole and exclusive property of the PURCHASER. Thus, the PURCHASER and the ACQUIRED COMPANY agree that without the prior written
consent of ACQUIRED COMPANY, the PURCHASER will (i) not use the Confidential Information to the detriment of the ACQUIRED COMPANY;
and (ii) hold the Confidential Information in strict confidence, and without limiting the foregoing, not disclose the Confidential
Information to any Person (other than the PURCHASER or the PURCHASER’s Affiliates); provided, however, that the agreements
in clause (ii) will not apply to the extent either

 

(A)
the same information is currently publicly available or becomes publicly available and that such public availability does not
result from the misappropriation or improper disclosure of such information by the PURCHASER; or

 

(B)
the Confidential Information is required by Applicable Law, a subpoena or a government investigation to be disclosed, but then
only

 

    	 	 	Page 7 of 16

     

    

 

(1)
to the extent disclosure is required and

 

(2)
after giving the ACQUIRED COMPANY and the SELLING MEMBER prior notice of such obligation so that it may seek a protective order
or other similar or appropriate relief if allowed by Applicable Law. The existence and terms of this Agreement, all other agreements
and documents contemplated by this Agreement, and the terms of the transactions contemplated by this Agreement (collectively,
the “Transaction Documents”) shall constitute “Confidential Information” for the purposes of this Section
8.1 and this Agreement; provided, however, that disclosure of the Transaction Documents by the ACQUIRED COMPANY is permitted

 

(C)
to Persons from whom a consent may be required to satisfy a condition to Execution,

 

(D)
to comply with Applicable Law, a subpoena or government investigation, or an IRS audit or Proceeding provided that the notice
requirement in Section 8.1(B)(2) has been complied with,

 

(E)
with the prior written consent of the ACQUIRED COMPANY,

 

(F)
to the PURCHASER’s professional advisors on a need-to-know basis subject to the agreement by such advisors to keep the Transaction
Documents confidential, and

the financing sources of the PURCHASER or holders of any Indebtedness of the PURCHASER set forth in Section 8.1(B)(2)(v) of the

Indemnified Party”) against, and hold each PURCHASER Indemnified Party harmless against, any and all Losses suffered
or incurred by such PURCHASER Indemnified Party, resulting from or arising out of any of the following:

    	 	 	Page 8 of 16

8.2.5
any acts or omissions of Purchaser following the Execution Date.

 

8.3
Indemnification Claims.

 

8.3.1
In order for a PURCHASER Indemnified Party or a Seller Indemnified Party (in either case, an “Indemnified Party”)
to be entitled to any indemnification provided for under Section 8.1 or Section 8.2 in respect of, arising out of or involving
a claim by a third party asserting that an Indemnified Party is liable to such third party for a monetary or other obligation
which may constitute or result in Losses for which such Indemnified Party may be entitled to indemnification pursuant to this
Section 8 (a “Third Party Claim”), such Indemnified Party must notify the Seller Indemnifying Party or the PURCHASER,
as applicable (the “Indemnifying Party”), in writing of the Third Party Claim within thirty (30) days after receipt
by such Indemnified Party of notice of the Third Party Claim (a “Claims Notice”); provided, however, that failure
to give such notification shall not affect the indemnification provided under Section 8.1 or Section 8.2 except to the extent
the Indemnifying Party has been actually prejudiced as a result of such failure, and it being understood that claims for a breach
of a representation or warranty must be delivered on or before the expiration of the survival period for such representation or
warranty under Section 8.4. The Claims Notice shall set forth in reasonable detail

 

    	 	 	Page 9 of 16

     

    

 

(i)
the specific representations, warranties and covenants that the Indemnified Party alleges have been breached (or would constitute
a breach if such Third Party Claim is true) and the relevant provision under Section 8.1 or Section 8.2 under which the right
to indemnification is claimed, and

 

(ii)
the relevant information available to the Indemnified Party relating to such Third Party Claim and the Indemnified Party’s
conclusion that such Third Party Claim constitutes (or would constitute, if true) a breach.

 

8.3.2
If an Indemnified Party gives a Claims Notice to the Indemnifying Party pursuant to Section 8.3.1 of the assertion of a Third
Party Claim, the Indemnifying Party shall be entitled to participate in the defense of such Third Party Claim and, to the extent
that it wishes (unless the Indemnifying Party is also a Person against whom the Third Party Claim is made and the Indemnified
Party determines in good faith that joint representation would be inappropriate), to assume the defense of such Third Party Claim
with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party
of its election to assume the defense of such Third Party Claim, the Indemnifying Party shall not, so long as it diligently conducts
such defense, be liable to the Indemnified Party under this Section 8 for any fees of other counsel or any other expenses with
respect to the defense of such Third Party Claim, in each case subsequently incurred by the Indemnified Party in connection with
the defense of such Third Party Claim, other than reasonable costs of investigation. If the Indemnifying Party assumes the defense
of a Third Party Claim, no settlement of such Third Party Claim may be effected by the Indemnifying Party without the Indemnified
Party’s consent unless

 

(i) there is no finding or
admission that the Indemnified Party violated any Applicable Law or violated the rights of any Person;

 

(ii) the sole relief provided is monetary damages
that are paid in full by the Indemnifying Party;

 

(iii) the settlement is contained in a written
agreement;

 

(iv) the settlement agreement provides an unconditional
release and discharge of the Indemnified Party; and

 

(v) the Indemnified Party
has not reasonably objected to the settlement on grounds that the settlement could reasonably be expected to have a material adverse
effect on the continuing business interests of the Indemnified Party.

 

8.3.3
Notwithstanding the foregoing in Section 8.3.2, if an Indemnified Party determines in good faith that

 

    	 	 	Page 10 of 16

     

    

 

(i) there is a reasonable
probability that a Third Party Claim may adversely affect it other than as a result of monetary damages for which it would be
entitled to indemnification under this Agreement,

 

(ii) the Indemnifying Party
has previously breached its indemnification obligations under this Agreement or has failed to diligently carry out the defense
of a Third Party Claim, or

 

(iii) upon
advice of counsel, having common counsel with the Indemnifying Party (if the Third Party Claim is asserted against both) would
present such counsel with a conflict of interest or that, upon advice of counsel, there may be legal defenses available to such
Indemnified Party which are different from or in addition to those available to the Indemnifying Party, then the Indemnified Party
may, by notice to the Indemnifying Party, assume the exclusive right to defend or settle such Third Party Claim. The Indemnified
Party shall not be entitled to be indemnified or held harmless under Section 8.1 or Section 8.2 for such Third Party Claim if
the Indemnified Party settles such Third Party Claim without the prior written consent of the Indemnifying Party, unless the Indemnified
Party has sought such consent and such consent has been unreasonably withheld or delayed, it being agreed that (i) the Indemnifying
Party shall not unreasonably withhold or delay such consent and (ii) it shall not be unreasonable for the Indemnifying Party to
withhold or delay its consent if the settlement

 

(A)
includes any finding or admission that the Indemnifying Party (or any Affiliate thereof) violated any law or the rights of any
Person,

 

(B)
is not entirely contained in a written agreement

 

(C)
would lead to Liability or create any financial or other obligation on the part of the Indemnifying Party in excess of the amount
for which the Indemnifying Party is obligated to indemnify under this Section 8,

 

(D) would impose any injunctive
relief or obligation of specific performance on the Indemnifying Party or

 

(E) does not include an
unconditional release and discharge of the Indemnifying Party in a form reasonably satisfactory to the Indemnifying Party. In
the event the Indemnified Party assumes defense of a Third Party Claim pursuant to this Section 8.3.3, the Indemnifying Party
shall have the right, at its own expense, to defend itself with respect to such Third Party Claim and to participate in the defense
of the matter through counsel of its own choosing.

 

8.3.4 With
respect to any Third Party Claim subject to indemnification under this Article 8, the Parties agree: (i) to keep each other informed
of the status of such Third Party Claim and any related proceedings at all stages thereof where such Person is not represented
by its own counsel; (ii) to render to each other (at their own expense) such assistance as they may reasonably require of each
other and to cooperate in good faith with each other to ensure the proper and adequate defense of any Third Party Claim; and (iii)
to cooperate in such a manner as to preserve (to the extent reasonably possible) the confidentiality of all information of the
Parties and the attorney client and work product privileges.

 

    	 	 	Page 11 of 16

     

    

 

8.3.4.1
In order for an Indemnified Party to be entitled to any indemnification provided for under Section 8.1 or Section 8.2 other than
in respect of, arising out of or involving a Third Party Claim, such Indemnified Party shall deliver written notice of such claim
(setting forth in reasonable detail (i) the specific representations, warranties and covenants that the Indemnified Party alleges
have been breached and the relevant provision under Section 8.1 or Section 8.2 under which
the right to indemnification is claimed, and (ii) the relevant information available to the Indemnified Party relating to such
claim and the Indemnified Party’s conclusion that such claim constitutes a breach) with reasonable promptness to the Indemnifying
Party; provided, however, that failure to promptly give such notification shall not affect the indemnification provided under
Section 8.1 or Section 8.2 except to the extent the Indemnifying Party has been actually prejudiced as a result of such failure,
and it being understood that claims for breach of a representation or warranty must be delivered before the expiration of the
applicable survival period for such representation or warranty under Section 8.4. If the Indemnifying Party does not notify the
Indemnified Party, in writing, within thirty (30) days following its receipt of such notice, that the Indemnifying Party disputes
the Indemnified Party’s claim for indemnification, such claim shall be conclusively deemed a Liability of the Indemnifying
Party for which the Indemnified Party is entitled to indemnification under this Section 8, and the Indemnified Party shall be
entitled to recover the amount of the Losses stated in such notice.

 

8.3.4.2
Notwithstanding the other provisions of this Section 8.3, if a third party asserts (other than by means of a lawsuit) that an
Indemnified Party is liable to such third party for a monetary or other obligation which would reasonably be expected to constitute
or result in Losses for which such Indemnified Party may be entitled to indemnification pursuant to this Section 8, and such Indemnified
Party reasonably determines that it has a valid business reason to fulfill such obligation, then

 

(i) such Indemnified Party
shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party,

 

(ii) such Indemnified Party
may subsequently make a claim for indemnification in accordance with the provisions of this Section 8, and

 

(iii) such Indemnified Party
shall be reimbursed, in accordance with the provisions of this Section 8, for any such Losses for which it is entitled to indemnification
pursuant to this Section 8 (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement
to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Section 8).

 

8.4
Survival. Regardless of any investigation made by either Party in connection with this Agreement, any notice to either Party
under this Agreement, or any waiver of any closing condition set forth in Article 2, all representations and warranties in this
Agreement and all rights of either Party to indemnification as set forth in Section 8.1 or 8.2 above shall survive the Execution
until the date that is twelve (12) months after the Execution Date (the “Expiration Date”); provided, further, however,
that such obligations to indemnify and hold harmless shall not terminate with respect to any Losses as to which the Indemnified
Party shall have, on or prior to such Expiration Date, previously made a claim by delivering a notice of such claim to the Indemnifying
Party as provided above in this Section 8. Notwithstanding anything to the contrary contained in this Agreement, no party shall
have any indemnification obligation under this Agreement for any claim or breach of a representation or warranty unless written
notice of such breach has been timely given in accordance with Section 8.3 on or prior to the Expiration Date.

 

    	 	 	Page 12 of 16

     

    

 

8.5
Limitations. Notwithstanding anything to the contrary contained in this Agreement,
the following limitations shall apply to indemnification claims under this Agreement

 

8.5.1
No PURCHASER Indemnified Party shall be entitled to indemnification until the entire PURCHASER Price has been paid to ACQUIRED
COMPANY and SELLING MEMBER.

 

8.5.2
No PURCHASER Indemnified Party shall be entitled to be indemnified for any Losses under Section 9.1.1 unless the aggregate amount
of all Losses which the PURCHASER Indemnified Parties have incurred or would incur, but for this Section 9.1.1, exceeds on a cumulative
basis an amount equal to $50,000 (the “Deductible”) and then only for the excess over the Deductible.

 

9.5.3
Notwithstanding anything to the contrary, express or implied, in this Agreement, the total liability of the Seller Member for
any claims or indemnification obligations arising from or relating to this Agreement or the transactions contemplated hereby shall
not exceed Two Million Dollars ($2,000,000).

 

8.6
Payment Procedure; Set Offs. For purposes of determining the amount of any Losses, which may be set off against any amounts
due to ACQUIRED COMPANY from PURCHASER, such amount shall be reduced by the amount of (a) insurance benefits and proceeds actually
received in respect of the Losses, net of any deductible amounts and costs of collection, (b) any actual recovery (whether by
way of payment, discount, credit, off-set, tax benefit, counterclaim or otherwise) received from a third party, less any costs
of collection, and (c) any tax-related benefits that may be realized or received in respect of such Losses (including any tax
refunds that are received as a result of such Losses and any amounts credited against taxes that would otherwise be owed).

 

8.7
Character of Damages. The Parties hereto agree that any payment of Losses to any Indemnified Party made pursuant to this Section
8 shall be treated as an adjustment to the Cash Consideration for all tax purposes.
