(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, 4 and 5 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 undersigned
that may be necessary or desirable to complete and execute any such Forms
3, 4 and 5 and timely file such forms with the Securities and Exchange
Commission and any stock exchange or similar authority, if required; and

(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 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 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, 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 each of the foregoing attorneys-in-fact, in
serving in such capacity at the request of the undersigned, is not
assuming, nor is the Company assuming, 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 the undersigned to each

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 by the undersigned to such attorney-in-fact
for purposes of executing, acknowledging, delivering and filing Forms 3, 4
or 5 (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, 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 14th day of February 2022.
