conditions set forth in this Agreement to make to the Borrower Revolving Loans from time to time in amounts not to exceed in the aggregate at any one time outstanding the Revolving Loan Commitment. Subject to the terms of this Agreement, the
Borrower may borrow, prepay (in whole or in part) and reborrow the Revolving Loans prior to (but not on) the Termination Date. The Revolving Loans made by the Lender shall be evidenced by the Revolving Credit Note. 

(b) Prior to an Event of Default, and except as otherwise provided herein, each Revolving Loan shall bear interest on the unpaid
principal balance before maturity (whether upon demand, acceleration, default or otherwise) at the rate per annum equal to the LIBOR Rate. Interest shall be computed daily based on the actual number of days elapsed and a year of 360 days.

 (c) From the date of the first Revolving Loan and until all Revolving Loans are paid in full, the Borrower shall pay to the
Lender all accrued and unpaid interest on each Revolving Loan on the first day of each month; provided that accrued and unpaid interest during the occurrence and continuation of an Event of Default shall be payable upon demand. The Lender may
debit to the Borrower’s Loan Account all unpaid and accrued interest on the Revolving Loans when due without prior notice to or consent of the Borrower. 
 (d) Notwithstanding anything to the contrary herein, all outstanding unpaid principal and accrued interest on the Revolving Loans shall be due and payable to the Lender on the Termination Date.

 (e) The Borrower may obtain Revolving Loans by submitting a Loan Request in writing,
including but not limited to submissions via facsimile, emails and/or documents in electronic format. Such request shall be received by the Lender by 2:00 p.m. (New York time) two (2) New York Banking Days before the Borrowing Date set forth in
the Loan Request and shall specify (i) such Borrowing Date, and (ii) the amount of the Revolving Loan requested. Once submitted, each Loan Request shall be irrevocable and no Loan Request may be modified, altered or amended without the
prior written consent of the Lender. Each Revolving Loan shall be in the principal amount of the lesser of (i) $100,000 or a multiple thereof, and (ii) the Maximum Available Commitment. Upon fulfillment of the conditions specified in
Section 4 hereof, the Lender shall promptly deposit the amount of such Revolving Loan in the operating account of the Borrower maintained with the Lender. 
 2.2 Interest After Default. After and during the continuation of an Event of Default, each of the Obligations shall bear interest at the rate of three percent (3%) per annum in excess
of the applicable rates set forth in this Agreement. In no event shall the interest rate under the Notes exceed the highest rate permitted by law. 
 2.3 Loan Account. The Lender will enter as a debit to the Loan Account the aggregate principal amount of each Obligation as disbursed or issued from time to time. The Lender shall also record in
the Loan Account, in accordance with the Lender’s customary accounting practices, all accrued interest and all other charges, expenses and other items properly chargeable to the Borrower hereunder or under the Related Documents, all payments
made by the Borrower with respect to the Obligations, and all other debits and credits. Once each month, the Lender shall render a statement of account of the Loan Account (including a statement of the outstanding principal balance of the Loans,
accrued and unpaid interest on the Loans, accrued fees and expenses and the applicable interest rate for each Loan) which statement shall be considered correct and conclusively binding upon the Borrower absent manifest error. Notwithstanding the
foregoing, neither the failure to make any such debit or recordation nor any error in any such entry shall affect the Revolving Credit Commitment or the Obligations in respect of any applicable Loans. 

2.4 Payments. All payments by the Borrower of principal, interest, fees and other Obligations shall be made in Dollars in same day
funds, without defense, setoff, counterclaim, reduction or deduction, and free of any restriction or condition, and delivered to the Lender not later than 12:00 noon (New York time) on the date due at U.S. Bank National Association, 425 Walnut,
Cincinnati, OH 45202, ABA #042000013, GL #03000001584, Account #152310887715, it being understood and agreed that funds received by the Lender after such time on any date shall be deemed to have been paid by the Borrower on the next succeeding
Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day which is not a Business Day, such payment may be made on the next succeeding Business Day in Dollars in same day funds, and such extension of time shall in
such case be included in the computation of payment of interest on the Notes. The Lender may debit to the depository accounts maintained by the Borrower with the Lender all payments on the Obligations when due without prior notice to or consent of
the Borrower. 
 2.5 Prepayments. 
 (a) Optional Prepayments. Subject only to the payment of any amounts required by Section 2.6 hereof, the Borrower may, at its option and at any time, prepay the Obligations in


  
 -13-









 
whole or in part; provided, however, that (i) the Bank shall have received from the Borrower notice of such prepayment (which shall be irrevocable and shall specify the Loan and the
amount to be prepaid and the date of such prepayment) not later than 3:00 p.m. on a Business Day that is at least three (3) Business Day’s prior to the date specified in such notice for prepayment, and (ii) any prepayment of a Loan
shall be in a principal amount of $100,000 or a whole multiple of $100,000 in excess thereof, or, if less, the entire principal amount thereof then outstanding. 
 (b) Mandatory Prepayment. At any time that the aggregate principal amount of Revolving Loans outstanding hereunder exceeds the Revolving Loan Commitment, the Borrower shall immediately pay the
amount of such excess in immediately available funds, together with interest accrued on the amount of such payment. 
 2.6
General Provisions Applicable to LIBOR Rate Loans. 
 (a) In the event the Lender shall incur any loss, cost, expense or
premium (including any loss of profit or loss, cost, expense or premium incurred by reason of the liquidation or reemployment of deposits or other funds acquired or contracted to be acquired by the Lender to fund or maintain LIBOR Loans or the
relending or reinvesting of such deposits or other funds or amounts paid or prepaid to the Lender), as a result of any failure by the Borrower to borrow any LIBOR Loan on the date specified in the applicable Loan Request given pursuant to this
Agreement; then upon the demand of the Lender, the Borrower shall pay to the Lender such amount as will reimburse the Lender for such loss, cost, expense or premium. If the Lender requests such a reimbursement it shall provide the Borrower with a
certificate setting forth the computation of the loss, cost, expense or premium giving rise to the request for reimbursement in reasonable detail and such certificate shall be deemed prima facie correct. 

(b) If the Lender reasonably determines that (i) by reason of circumstances affecting the London Interbank Eurodollar Market
adequate and reasonable means do not exist for ascertaining the applicable LIBOR Rate; or (ii) the LIBOR Rate will not adequately and fairly reflect the cost to the Lender of maintaining or funding Loans based on the LIBOR Rate, or that the
maintenance or funding of such Loans based on the LIBOR Rate has become impracticable as a result of an event occurring after the date of this Agreement which in the opinion of the Lender Materially affects such Loans; then so long as such
circumstances shall continue, the Lender shall not be under any obligation to make or continue Loans based on the LIBOR Rate, and during such time the Loans may bear interest at the Prime Rate. 

2.7 Effect of Regulatory Change. If there shall occur any adoption or implementation of, or change to, any Regulation, or
interpretation or administration thereof, which shall have the effect of imposing on the Lender (or the Lender’s holding company) any increase or expansion of or any new: Tax (excluding taxes on its overall income and franchise taxes), charge,
fee, assessment or deduction of any kind whatsoever, or reserve, capital adequacy, special deposits or similar requirements against credit extended by, assets of, or deposits with or for the account of the Lender or other conditions affecting the
extensions of credit under this Agreement; then the Borrower shall pay to the Lender such additional amount as the Lender deems necessary to compensate the Lender for any increased cost to the Lender attributable to the extension(s) of credit under
this Agreement and/or for any reduction in the rate of return on the Lender’s capital and/or the Lender’s revenue attributable to such extension(s) of credit. If the Lender requests such a reimbursement it shall


  
 -14-









 
provide the Borrower with a certificate setting forth the computation of the increased costs or reduction in rate of return giving rise to the request for reimbursement in reasonable detail and
such certificate shall be deemed prima facie correct. Such amount(s) shall be payable within 15 days of demand and, if recurring, as otherwise billed by the Lender. 
 2.8 Taxes; Withholding, Etc. If any Tax is required to be withheld or deducted from, or is otherwise payable by the Borrower in connection with, any payment due to the Lender under this
Agreement or the Related Documents, the Borrower (a) shall, if required, withhold or deduct the amount of such Tax from such payment and, in any case, pay such Tax to the appropriate taxing authority in accordance with applicable law and
(b) shall pay to the Lender (i) such additional amounts as may be necessary so that the net amount received by the Lender with respect to such payment, after withholding or deducting all Taxes required to be withheld or deducted, is equal
to the full amount payable under this Agreement or the Related Documents and (ii) an amount equal to all Taxes payable by the Lender as a result of payments made by the Borrower (whether to a taxing authority or to the Lender) pursuant to this
Section 2.8. If any Tax is withheld or deducted from, or is otherwise payable by the Borrower in connection with, any payment due to the Lender under this Agreement or the Related Documents, the Borrower shall, within 30 days after the date of
such payment, furnish to the Lender the original or a certified copy of a receipt for such Tax from the applicable taxing authority. If any payment due to the Lender under this Agreement or the Related Documents is or is expected to be made without
withholding or deducting therefrom, or otherwise paying in connection therewith, any Tax payable to any taxing authority, the Borrower shall, within 30 days after any request from the Lender, furnish to the Lender a certificate from such taxing
authority, or an opinion of counsel acceptable to the Lender, in either case stating that no Tax payable to such taxing authority was or is, as the case may be, required to be withheld or deducted from, or otherwise paid by the Borrower in
connection with, such payment. 
 2.9 No Obligation to Extend or Forbear. The Borrower acknowledges and agrees that the
Lender: (a) upon execution hereof, has no duty or obligation of any kind to, and has made no representations of any kind or nature that the Lender will, extend credit or any other kind of financial accommodations to the Borrower after the
Termination Date, or forbear at any time from the exercise of any of its rights or remedies under this Agreement, the Related Documents and applicable law; and (b) may at any time, in its sole and absolute discretion, exercise whatever rights
and remedies the Lender may have under this Agreement, the Related Documents and applicable law. All Obligations shall be due in full on the Termination Date without further notice or demand.

connection with the transactions contemplated hereby and which will, or which in the future may (so far as the Borrower can reasonably foresee), cause a Material Adverse Effect. 

3.8 Ownership of Property. The Borrower and each of its Subsidiaries has good and marketable title to all of its Material
Property, including the Property reflected in the Borrower’s consolidated balance sheets most recently delivered to or received by the Lender. There are no Material Liens of any nature on any of the Property of the Borrower and its Subsidiaries
except Permitted Liens. All Property useful or necessary in the Borrower’s and its Subsidiaries’ business, whether leased or owned, is in adequate condition and, to the best of the Borrower’s knowledge after due inquiry, conforms in
all Material respects to all applicable Requirements of Law. The Borrower and each Subsidiary owns (or is licensed to use) and possesses all such patents, trademarks, trade names, service marks, copyrights and rights with respect to the foregoing as

and hereafter shall continue to be located at the Borrower’s principal place of business and chief executive office. 

3.12 Other Names. Except as provided on Schedule 3.12 hereto, the business conducted by the Borrower (and not of its Subsidiaries)
has not been conducted under any other corporate, trade or fictitious name during the last five years, and following the date hereof the Borrower will not conduct its business under any other corporate, trade or fictitious name unless the Borrower
shall have delivered at least thirty (30) days’ prior written notice to the Lender of such name change. 
 3.13 Not
an Investment Borrower. The Borrower is not (a) an “investment Borrower” or a Borrower “controlled by an investment Borrower” within the meaning of the Investment Borrower Act of 1940, as amended, or (b) a
“holding Borrower” or a “subsidiary” of a “holding Borrower” or an “affiliate of a “holding Borrower” within the meaning of the Public Utility Holding Borrower Act of 2005. 

3.14 No Defaults. Neither the Borrower nor any Subsidiary is in default under or in violation of (a) any Requirements of Law,
(b) any covenant, indenture, deed, lease, agreement, mortgage, deed of trust, note or other instrument to which the Borrower or any Subsidiary is a party or by which the Borrower or any Subsidiary is bound, or to which any of its Property is
subject, or (c) any Indebtedness; or if any default or violation under Sections 3.14(a), (b) or (c) exists, the failure to cure such default or violation would not result in a Material Adverse Effect. 

3.15 Environmental Laws. The business of the Borrower and each of its Subsidiaries has been operated in all Material respects in
compliance with all Environmental Laws and neither the Borrower nor any Subsidiary is subject to any known Environmental Liability relating to the conduct of its business or the ownership of its Property and no facts or circumstances are known by
the Borrower, after due inquiry, to exist which could give rise to such Environmental Liabilities, except for such Environmental Liabilities that in the aggregate would not cause a Material Adverse Effect. No notice has been served on the Borrower
or any Subsidiary claiming any violation of Environmental Laws, asserting Environmental Liability or demanding payment or contribution for Environmental Liability or violation of Environmental Laws which would cause a Material Adverse Effect.

 3.17 Restricted Payments. Other than declared dividends and distributions consistent
with the Borrower’s past practices or as otherwise permitted under this Agreement, the Borrower has not, since the date of the most recent financial statements referred to in Section 3.2 and as of the date hereof, made any Restricted
Payments. 
 3.18 Solvency. The Borrower is not “insolvent,” nor will the Borrower’s incurrence of loans,
direct or contingent, to repay the Obligations render the Borrower “insolvent.” For purposes of this Section 3.18, a corporation is “insolvent” if (i) the “present fair salable value” (as defined below) of its
assets is less than the amount that will be required to pay its probable liability on its existing debts and other liabilities (including contingent liabilities) as they become absolute and matured; (ii) its property constitutes unreasonably
small capital for it to carry out its business as now conducted and as proposed to be conducted including its capital needs; (iii) it intends to, or believes that it will, incur debts beyond its ability to pay such debts as they mature (taking
into account the timing and amounts of cash to be received by it and amounts to be payable on or in respect of debt of it), or the cash available to it after taking into account all of its other anticipated uses of the cash is anticipated to be
insufficient to pay all such amounts on or in respect of its debt when such amounts are required to be paid; or (iv) it believes that final judgments against it in actions for money damages will be rendered at a time when, or in an amount such
that, it will be unable to satisfy any such judgments promptly in accordance with their terms (taking into account the maximum reasonable amount of such judgments in any such actions and the earliest reasonable time at which such judgments might be
rendered), or the cash available to it after taking into account all other anticipated uses of its cash, is anticipated to be insufficient to pay all such judgments promptly in accordance with their terms. For purposes of this Section 3.18, the
following definitions shall apply: (x) the term “debts” includes any legal liability, whether matured or unmatured, liquidated, absolute, fixed or contingent, (y) the term “present fair salable value” of
assets means the amount which may be realized, within a reasonable time, either through collection or sale of such assets at their regular market value and (z) the term “regular market value” means the amount which a capable
and diligent businessman could obtain for the property in question within a reasonable time from an interested buyer who is willing to purchase under ordinary conditions. 
 3.19 Bank Holding Company. The Borrower has complied in all Material respects with all federal, state and local laws pertaining to bank holding companies, including the Bank Holding Company Act of
1956 (12 U.S.C. § 1841(a)(2)(A) et seq.) and Chapter 202 of the Texas Finance Code, and there are no unsatisfied conditions precedent to its engaging in the business of being a registered bank holding company. 

3.20 FDIC Insurance. The deposits held by each Bank Subsidiary of the Borrower are insured by the FDIC to the maximum extent
permitted by applicable federal law and no event, act or omission has occurred which would adversely affect the status of any Bank Subsidiary as an FDIC-insured bank. 
 3.21 Investigations. Neither the Borrower nor any Bank Subsidiary is (a) to the Borrower’s knowledge, under investigation by any Regulatory Authority or any other Governmental Authority
which would cause a Material Adverse Effect, or (b) is operating under any Material formal or informal restrictions or understandings imposed by or agreed to in connection with any Regulatory Authority or any other Governmental Authority.

 DEFINITIVE AGREEMENT  

NEGATIVE PLEDGE AGREEMENT 
 This NEGATIVE PLEDGE AGREEMENT (this “Agreement”) is made as of this 4th day of June, 2014, by INDEPENDENT BANK GROUP, INC., a Texas corporation and a registered bank holding company (the
“Borrower”), in favor of U.S. BANK NATIONAL ASSOCIATION, a national banking association (the “Lender). 
 RECITALS 
 The Lender has entered into the Credit Agreement with the
Borrower pursuant to which the Lender has agreed to extend credit to the Borrower upon the terms set forth in the Credit Agreement. The Lender would not have agreed to extend such credit but for this Agreement. 

NOW, THEREFORE, in consideration of the extension of credit to the Borrower, and for other good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged, the Borrower hereby agrees: 
 AGREEMENT 

1. Definitions. Capitalized terms used herein without definition shall have the meanings ascribed thereto in the Credit Agreement
(as hereinafter defined). In addition, the following terms used in this Agreement shall have the following meanings: 

“Credit Agreement” shall mean the Credit Agreement by and between the Borrower and the Lender dated as of the date
hereof, as the same may be amended, modified, extended, supplemented or restated from time to time hereafter. 

“Shares” shall mean, collectively, 100% of the issued and outstanding capital stock, equity and other ownership
interests (and any rights to acquire any of such interests) of each Bank Subsidiary owned by the Borrower, and any further securities, warrants, options, rights, cash or property issued as an addition to, in substitution of, in exchange for, or with
respect to such ownership interests. 
 2. Negative Pledge. The Borrower covenants and agrees that, unless consented to
by the Lender, from and after the date of this Agreement and until the Termination Date and until all Obligations to the Lender are paid in full, the Borrower will (a) not sell, option, exchange or otherwise convey any legal, equitable or
beneficial interest in the Shares or any part thereof, and (b) keep the Shares free and clear from any pledge, mortgage, security interest, hypothecation, lien, charge, encumbrance, conditional sale agreements, rights or claims of third
parties, other burdens and any security interest therein, other than Permitted Liens. 







 3. Certain Representations and Warranties. The Borrower represents and warrants to
the Lender as follows: 
 (a) Ownership. The Borrower is the record and beneficial owner of all the Shares. The Shares
represent, and during the term of this Agreement will represent, all of the issued and outstanding capital stock, equity and other ownership interests (and any rights to acquire any of such interests) of each Bank Subsidiary. 

(b) Authority. The Borrower has all necessary power and authority to enter into this Agreement and perform its obligations
hereunder. The execution, delivery and performance of this Agreement: (i) do not require the approval of any Governmental Authority or other Person; and (ii) will not violate any law, agreement or restriction by which the Borrower is
bound. This Agreement is the legal, valid and binding obligation of the Borrower and is enforceable against it in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
or limiting creditors’ rights generally or by equitable principles relating to enforceability. 
 (c) Title. The
Shares are genuine, and the Borrower has good title to the Shares. The Shares are owned by the Borrower free and clear of any pledge, mortgage, security interest, hypothecation, lien, charge, encumbrance, conditional sale agreements, rights or
claims of third parties, other burdens and any security interest therein, other than Permitted Liens. 
 4. Default;
Expenses. The failure of the Borrower to comply with any term of this Agreement shall constitute an Event of Default under the Credit Agreement. In addition, the Borrower shall reimburse the Lender (and any agent or representative of the Lender)
for any expenses incurred by the Lender (or such agent or representative of the Lender) in protecting or enforcing its rights under this Agreement, including, without limitation, reasonable attorneys’ fees. 

5. Further Assurances. The Borrower agrees to execute and deliver, or cause to be executed and delivered, all such other papers
and to take all such other actions as the Lender may reasonably request from time to time in order to carry out the purposes of this Agreement. 
 6. Term. When all of the Obligations are irrevocably and fully paid and fully discharged and the Lender shall have no further obligation or commitment to advance or extend credit to the Borrower
under the Credit Agreement, this Agreement shall terminate. Notwithstanding the foregoing, this Agreement shall apply to all extensions, renewals, refinancings or modifications, if any, of the Obligations. 

7. Miscellaneous. 
 (a) Waivers. No failure to exercise and no delay in exercising on the part of the Lender any right, power or remedy under this Agreement shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The failure of the Lender to insist upon the strict observance or enforcement of any
provision of this Agreement shall not be construed as a waiver or relinquishment of such provision. Any waiver of any right, power, remedy, term or condition contained herein shall only be effective if it is in writing and signed by the Lender.

 (b) Amendments. This Agreement may only be amended by a writing executed by the Borrower and the Lender.

with the internal laws of the State of New York.

same agreement. 
 (f) Headings. The Section headings set forth in this Agreement are for convenience of reference only
