(“IBG”), INTEGRITY BANCSHARES, INC., a Texas corporation with its principal offices in Houston, Texas (“IBI”), and the shareholders of IBI whose names are set forth on the signature page hereto (individually, a
“Shareholder” and collectively, the “Shareholders”). 
 RECITALS: 

WHEREAS, IBI and IBG are parties to that certain Agreement and Plan of Reorganization, dated as of November 28, 2017 (the
“Reorganization Agreement”), which provides for the acquisition of IBI by IBG through the merger of IBI with and into IBG (the “Merger”). Terms with their initial letter capitalized and not otherwise defined herein
shall have the meanings given them in the Reorganization Agreement; 
 WHEREAS, the Reorganization Agreement requires that IBI deliver this
Voting Agreement to IBG; and 
 WHEREAS, IBI and IBG are relying on this Voting Agreement in incurring expenses in reviewing the business of
IBI, in preparing the Registration Statement and related Proxy Statement for the meeting of shareholders of IBI, in proceeding with the filing of applications for regulatory approvals, and in undertaking other actions necessary for the consummation
of the Merger. 
 AGREEMENT: 

NOW, THEREFORE, for and in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, IBI, IBG and the Shareholders undertake, promise, covenant and agree with each other as follows: 
 1. As of the date
hereof, the Shareholders own the common shares of IBI (“IBI Shares”), set forth beside their respective names on Schedule 1 attached hereto. All such IBI Shares, and any IBI Shares hereafter acquired by such Shareholder,
(collectively, such Shareholder’s “Shares”), shall be subject to this Voting Agreement. 
 2. Each Shareholder
represents that he, she or it has the full legal capacity and authority to execute, deliver and perform this Voting Agreement, including the exclusive right to vote such Shareholder’s Shares. Each Shareholder hereby agrees to vote at the
shareholders’ meeting of IBI called to consider and act upon the Merger (the “Meeting”) such Shareholder’s Shares in favor of approval of the Reorganization Agreement, the Merger, and all of the agreements and transactions
contemplated by the Reorganization Agreement.

 3. If IBI conducts a meeting of, solicits written consents from or otherwise seeks a vote of its
shareholders with respect to any Acquisition Proposal (as that term is defined in the Reorganization Agreement) or any other matter which may contradict any provision of this Voting Agreement or may prevent IBG or IBI from consummating the Merger,
then each Shareholder shall vote such Shareholder’s Shares in the manner most favorable to consummation of the Merger and the transactions contemplated by the Reorganization Agreement. 

Notwithstanding, the foregoing sentence, the Shareholders may vote in favor of a Superior Proposal (as that term is defined in the
Reorganization Agreement). 
 4. Each Shareholder hereby covenants and agrees that, until this Voting Agreement is terminated in accordance
with its terms, each Shareholder will not, and will not agree to, directly or indirectly, without the prior written consent of IBG, (i) sell, assign, transfer or dispose of any of such Shareholder’s Shares, (ii) hypothecate such
Shareholder’s Shares under terms that would prevent the voting thereof, (iii) deposit such Shareholder’s Shares into a voting trust or enter into a voting agreement or arrangement with respect to such Shareholder’s Shares or
grant any proxy with respect thereto except as herein provided, or (iv) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer or other disposition of any of such
Shareholder’s Shares, in connection with a transaction pursuant to which 25% or more of the voting power of IBI Shares is, or control of IBI otherwise is, transferred to a person or entity other than a party to this Voting Agreement. 

Notwithstanding any of the foregoing, any Shareholder may (i) make such gifts of such Shareholder’s Shares as such Shareholder may
choose to make, or (ii) transfer such Shares to trusts or other entities controlled by the Shareholder or for estate planning purposes, so long as the recipient of such Shareholder’s Shares executes and delivers an amendment to this Voting
Agreement whereby such recipient becomes bound by the terms of this Voting Agreement. 
 5. This Voting Agreement shall continue in effect
until the earlier to occur of (i) the termination of the Reorganization Agreement, as it may be amended or extended from time to time, or (ii) the consummation of the transactions contemplated by the Reorganization Agreement. 

6. If a Shareholder transfers a certificate representing any of such Shareholder’s Shares before the Meeting, IBI shall require such
certificate to bear the following endorsement, noted conspicuously thereon: 
 “The shares represented by this certificate are subject
to the terms of a Voting Agreement dated November 28, 2017, a copy of which is on file in the principal office of Integrity Bancshares, Inc.” 

7. This Voting Agreement may not be modified, amended, altered or supplemented with respect to a particular Shareholder except upon the
execution and delivery of a written agreement executed by IBI, IBG and such Shareholder. 
 8. This Voting Agreement may be executed in any
number of counterparts, each of which shall be deemed an original but all of which shall constitute one and the same instrument. An electronic or facsimile transmission of a signed counterpart of this Voting Agreement shall be sufficient to bind the
party or parties whose signature(s) appear thereon.
