                               POWER OF ATTORNEY

       Know all by these presents, that the undersigned, Robert W. Stallings,
hereby constitutes and appoints each of Julie Anderson, Mary Helen Hall, Michael
W. Tankersley and Kristen Cunningham as the undersigned's true and lawful
attorney-in-fact to:

       (1)     execute for and on behalf of the undersigned, in the
               undersigned's capacity as an officer and/or director of Texas
               Capital Bancshares, Inc. (the "Company"), Forms 3, 4, and 5 in
               accordance with Section 16(a) of the Securities Exchange Act of
               1934 and the rules thereunder;

       (2)     do and perform any and all acts for and on behalf of the
               undersigned which may be necessary or desirable to complete and
               execute any such Form 3, 4, or 5, complete and execute any
               amendment or amendments thereto, and timely file such form with
               the SEC and any stock exchange or similar authority; and

       (3)     take any other action of any type whatsoever in connection with
               the foregoing, including the execution of a Form ID, which, in
               the opinion of such attorney-in-fact, may be of benefit to, in
               the best interest of, or legally required by, the undersigned, it
               being understood that the documents executed by such attorney-in-
               fact on behalf of the undersigned pursuant to this Power of
               Attorney shall be in such form and shall contain such terms and
               conditions as such attorney-in-fact may approve in such 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 such
attorney-in-fact, or such attorney-in-fact's substitute or substitutes, shall
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, in serving in such capacity at the request of the
undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934.

       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 the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.

       IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of this 18th day of February, 2014.


                                            /s/ Robert W. Stallings
                                            -----------------------
