                (including amendments thereto) in accordance with Section 16(a)
                of the Securities Exchange Act of 1934, as amended (the
                "Exchange Act"), and the rules and regulations thereunder;

        (2)     do and perform any and all acts for and on behalf of the

                appropriate; and

        (3)     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 the 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 attorney-in-fact, and
their substitutes, in serving in such capacity at the request of the
undersigned, are not assuming, nor is Equity Bancshares, Inc., any of the
undersigned's responsibilities to comply with Section 16 of the Exchange Act.

        The undersigned agrees that the 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 Equity Bancshares, Inc. and the 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 the 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 Equity Bancshares, 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 Equity
Bancshares, Inc., 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 the date written below.
