Power of Attorney

Know all by these presents, that the undersigned hereby 
constitutes and appoints each of Robert R. Franklin, Jr. and 
Robert T. Pigott, Jr., signing singly, the undersigned's true and 
lawful attorney-in-fact to:
 
(1) prepare, execute in the undersigned's name and on the 
undersigned's behalf, and submit to the U.S. Securities and 
Exchange Commission (the "SEC") a Form ID, including amendments 
thereto, and any other documents necessary or appropriate to 
obtain codes and passwords enabling the undersigned to make 
electronic filings with the SEC of reports required by 
Section 16(a) of the Securities Exchange Act of 1934, as amended 
(the "Exchange Act"), and the rules and regulations thereunder;
 
(2) execute for and on behalf of the undersigned Forms 3, 4 and 5 
(including amendments thereto) in accordance with 
Section 16(a) of the Exchange, and the rules and regulations 
thereunder;
 
(3)  do and perform any and all acts for and on behalf of the 
undersigned that may be necessary or desirable to complete and 
execute any such Form 3, 4 or 5, complete and execute any 
amendment or amendments thereto, file that Form with the SEC and 
any stock exchange or similar authority, and provide a copy as 
required by law or advisable to such persons
 as the attorney-in-
fact deems appropriate; and
 
(4) take any other action of any type whatsoever in connection 
with the foregoing that, in the opinion of the attorney-in-fact, 
may be of benefit to, in the best interest of, or legally 
required of the undersigned, it being understood that the 
documents executed by the attorney-in-fact on behalf of the 
undersigned pursuant to this Power of Attorney will be in such 
form and will contain such terms and conditions as the attorney-
in-fact may approve in the attorney-in-fact's discretion.
 
The undersigned hereby grants to each such attorney-in-fact full 
power and authority to do and perform any and every act and thing 
whatsoever requisite, necessary, or proper to be done in the 
exercise of any of the rights and powers herein granted, as fully 
to all intents and purposes as the undersigned might or could do 
if personally present, with full power of substitution or 
revocation, hereby ratifying and confirming all that the 
attorney-in-fact, or the attorney-in-fact's substitute or 
substitutes, will lawfully do or cause to be done by virtue of 
this Power of Attorney and the rights and powers herein 
granted.  The undersigned acknowledges that the foregoing 
attorneys-in-fact, and their substitutes, in serving in such 
capacity at the request of the undersigned, are not assuming, nor 
is CBTX, Inc., any of the undersigned's responsibilities to 
comply with Section 16 of the Exchange Act.
 
The undersigned agrees that each such attorney-in-fact may rely 
entirely on information furnished orally or in writing by or at 
the direction of the undersigned to the attorney-in-fact.  The 
undersigned also agrees to indemnify and hold harmless CBTX, Inc. 
and each such attorney-in-fact against any losses, claims, 
damages or liabilities (or actions in these respects) that arise 
out of or are based upon any untrue statements or omissions of 
necessary facts in the information provided by or at the 
direction of the undersigned, or upon the lack of timeliness in 
the delivery of information by or at the direction of the 
undersigned, to that attorney-in-fact for purposes of executing, 
acknowledging, delivering or filing any Form 3, 4 or 5 (including 
any amendment thereto) and agrees to reimburse CBTX, Inc. and the 
attorney-in-fact on demand for any legal or other expenses 
reasonably incurred in connection with investigating or defending 
against any such loss, claim, damage, liability or action.
 
This Power of Attorney shall remain in full force and effect 
until the undersigned is no longer required to file Forms 3, 4 
and 5 with respect to the undersigned's holdings of and 
transactions in securities issued by CBTX, Inc., unless earlier 
revoked by the undersigned in a signed writing delivered to the 
foregoing attorneys-in-fact.

Attorney to be executed as of the date written below.
