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 the
                Company, Forms 3, 4s and 5s in accordance with Section 16(a) of
                the Securities Exchange Act of 1934, as amended (the "Exchange

        (3)     take any other action of any type whatsoever in connection with
                the foregoing that, 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

        The undersigned hereby grants to each such attorney-in-fact full power
and authority to do and perform each 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 and revocation, hereby ratifying and confirming all that each such
attorney-in-fact, or each such attorney-in-fact's substitute or substitutes,

        The undersigned agrees that each such attorney-in-fact may rely entirely
on information furnished orally or in writing by the undersigned to each such
attorney-in-fact.  The undersigned also agrees to indemnify and hold harmless
the Company 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 on
any untrue statement or omission of necessary facts in the information provided

acknowledging, delivering and filing Forms 3, 4s or 5s (including amendments
thereto) and agrees to reimburse the Company and each such attorney-in-fact 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, 4s and 5s 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 28 day of June 2017.
