    <remarks>The reporting person retired from the issuer and thus no longer performs significant policy-making functions for the issuer.  Therefore,
the reporting person should no longer be considered an officer for purposes of Section 16. As a result, the reporting person is
no longer subject to Section 16 in connection with his transactions in the equity securities of Home BancShares, Inc. and therefore
will no longer report any such transactions on Form 4 or Form 5.</remarks>
