(1)	execute, deliver and file 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, and the rules and regulations thereunder (the "Exchange Act");
(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 United States Securities and Exchange Commission and any stock
exchange or similar authority;
(3)	seek or obtain, as the undersigned's representative and on the undersigned's
behalf, information on transactions in the Company's securities from any third
party, including brokers, employee benefit plan administrators and trustees, and
the undersigned hereby authorizes any such person to release any such
information to the undersigned and approves and ratifies any such release of
information; and
(4)	take any other action of any type whatsoever in connection with the
foregoing 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 Exchange Act.  The undersigned further acknowledges and agrees
that the attorney-in-fact and the Company are relying on written and oral
information provided by the undersigned to complete such forms and the
undersigned is responsible for reviewing the completed forms prior to their
filing.  The attorney-in-fact and the Company are not responsible for any errors
or omissions in such filings.  The attorney-in-fact and the Company are not
responsible for determining whether or not the transactions reported could be
matched with any other transactions for the purpose of determining liability for
short-swing profits under Section 16(b).

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
Company and the foregoing attorneys in fact.  This Power of Attorney revokes all
previous powers of attorney with respect to the subject matter of this Power of
Attorney.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of October 10, 2023.
