NOW, THEREFORE, for the new Confidential Information the Undersigned will be provided and for other good and valuable consideration contained herein and in the Merger Agreement, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.            Director Support. The Undersigned agrees to use his or her best efforts to refrain from harming the goodwill of any of the Transaction Parties, the Surviving Entity and the Surviving Bank and their respective subsidiaries, and their respective customer and client relationships during the term of this Agreement.

2.            Non-Disclosure Obligations. The Undersigned agrees that he or she will not make any unauthorized disclosure, directly or indirectly, of any Confidential Information of the Transaction Parties, the Surviving Entity or the Surviving Bank to third parties, or make any use thereof, directly or indirectly. The Undersigned also agrees that he or she shall deliver promptly to the applicable Transaction Party, the Surviving Entity or the Surviving Bank at any time at the reasonable request of such Transaction Party, the Surviving Entity or the Surviving Bank, without retaining any copies, all documents and other material in the Undersigned’s possession at that time relating, directly or indirectly, to any Confidential Information or other information of such Transaction Party, the Surviving Entity or the Surviving Bank, as applicable, or Confidential Information or other information regarding third parties, learned in such person’s position as a director, officer or shareholder of any of the Transaction Parties.

For purposes of this Agreement, “Confidential Information” means and includes the Transaction Parties,’ the Surviving Entity’s or the Surviving Bank’s confidential and/or proprietary information and/or trade secrets, including those of their respective subsidiaries, that have been and/or will be developed or used and that cannot be obtained readily by third parties from outside sources.

The term “Confidential Information” does not include any information that (i) at the time of disclosure or thereafter is generally available to and known to the public, other than by a breach of this Agreement by the disclosing party; (ii) was available to the disclosing party, prior to disclosure by the Transaction Parties, the Surviving Entity or the Surviving Bank, on a non-confidential basis from a source other than the Undersigned and is not known by the Undersigned, after reasonable investigation, to be subject to any fiduciary, contractual or legal obligations of confidentiality; or (iii) was independently acquired or developed by the Undersigned without violating any obligations of this Agreement. The Undersigned acknowledges that each of the Transaction Parties’ respective businesses are highly competitive, that this Confidential Information constitutes valuable, special and unique assets to be acquired by the Surviving Entity in the Merger and constitutes existing valuable, special, and unique assets held by the each of the Transaction Parties pre-Merger, and that protection of such Confidential Information against unauthorized disclosure and use is of critical importance to each of the Transaction Parties.

3.            Non-Competition Obligations. The Undersigned agrees that, for the period beginning on the Execution Date and continuing until the date that is two (2) years after the Effective Time of the Merger (the “Non-Competition Period”), the Undersigned will not, except as a director of Allegiance or CBTX or as an officer of a Transaction Party (as the case may be) prior to the Effective Time of the Merger, in any capacity, directly or indirectly:

4.            Non-Competition Covenant Reasonable. The Undersigned acknowledges that the restrictions imposed by this Agreement are legitimate, reasonable and necessary to protect Allegiance and CBTX’s combination into the Surviving Entity and the goodwill thereof. The Undersigned acknowledges that the scope and duration of the restrictions contained herein are reasonable in light of the time that the Undersigned has been engaged in the business of Allegiance and/or Allegiance Bank or of CBTX and/or CBTX Bank, as applicable, and the Undersigned’s relationship with the customers of Allegiance and/or Allegiance Bank or of CBTX and/or CBTX Bank, as the case may be. The Undersigned further acknowledges that the restrictions contained herein are not burdensome to the Undersigned in light of the other opportunities that remain open to the Undersigned. Moreover, the Undersigned acknowledges that he or she has and will have other means available to him or her for the pursuit of his or her livelihood after the Effective Time of the Merger.

5.            Consideration. In consideration for the above obligations of the Undersigned, in addition to those matters set forth in the Recitals to this Agreement, the Transaction Parties, as applicable, agree to provide the Undersigned with access to new Confidential Information relating to such Transaction Party’s business, which will become the Surviving Entity’s business after the Effective Time of the Merger, in a greater quantity and/or expanded nature than that already provided to the Undersigned. The Undersigned also will have access to, or knowledge of, new Confidential Information of third parties, such as actual and potential customers, suppliers, partners, joint venturers, investors, financing sources, etc., of certain of the Transaction Parties prior to the Merger and certain of the Transaction Parties after the Effective Time of the Merger.

6.            Injunctive Relief and Additional Remedies. The Undersigned acknowledges that the injury that would be suffered by Allegiance, CBTX or the Surviving Entity as a result of a breach of the provisions of this Agreement (including any provision of Section 3) would be irreparable and that an award of monetary damages to Allegiance, CBTX or the Surviving Entity, as the case may be, for such a breach would be an inadequate remedy. Consequently, each of Allegiance, CBTX and the Surviving Entity will have the right, in addition to any other rights it may have, to seek specific performance, to obtain injunctive relief to restrain any proposed or actual breach or threatened breach or otherwise to specifically enforce any provision of this Agreement without the obligation to post bond or other security in seeking such relief. Such equitable remedies are in addition to the right to obtain compensatory and punitive damages, and attorney’s fees, and, notwithstanding Allegiance’s, CBTX’s or the Surviving Entity’s, as applicable, right to so seek damages, the Undersigned waives any defense that an adequate remedy for Allegiance, CBTX or the Surviving Entity, as applicable, exists under law. If the Undersigned, on the one hand, or Allegiance, CBTX or the Surviving Entity, on the other hand, must bring suit to enforce this Agreement, the prevailing party shall be entitled to recover its attorneys’ fees and costs related thereto.

7.            Extension of Restrictive Covenant Period. In the event that Allegiance, CBTX or the Surviving Entity shall file a lawsuit in any court of competent jurisdiction alleging a breach of Section 3 of this Agreement by the Undersigned and Allegiance, CBTX or the Surviving Entity, as applicable, is successful on the merits of such lawsuit, then any time period set forth in this Agreement including the time periods set forth in Section 3, will be extended one month for each month the Undersigned was in breach of this Agreement, so that the Surviving Entity, Allegiance or CBTX is provided the benefit of the full Non-Competition Period.

8.            Effectiveness of this Agreement. This Agreement shall become effective on the Execution Date. This Agreement shall automatically terminate and be of no further force or effect if (a) the Merger Agreement is not executed on or prior to the Execution Date, or (b) the Merger Agreement (once executed) is terminated in accordance with its terms and the Merger does not occur.

9.            Waiver. The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither the failure nor any delay by either party in exercising any right, power, or privilege under this Agreement will operate as a waiver of such right power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege. To the maximum extent permitted by applicable law, (a) no claim or right arising out of this Agreement can be discharged by one party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other party; (b) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement.

10.            Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of Allegiance, CBTX and their respective successors and assigns, including, without limitation, any successor by merger, consolidation or stock purchase of Allegiance, CBTX and any Person that acquires all or substantially all of the assets of Allegiance or CBTX.

All notices, consents, waiver, and other communications under this Agreement must be in writing and will be deemed to have been duly given when (a) delivered by hand (with written confirmation of receipt), (b) sent by electronic mail, provided, that a copy is mailed by registered mail, return receipt requested, or (c) when received by the addressee, if sent by a nationally recognized overnight delivery service (receipt requested), in each case to the appropriate addresses and electronic mail addresses set forth below (or to such other address or to such other Person as any party hereto has last designated by notice to the other parties in accordance herewith):
