and each of them, as the 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, any and all Form 3, 4 or 5 reports
required to be filed by the undersigned in accordance with Section 16(a) of the
Securities Exchange Act of 1934, as amended ("Exchange Act"), and the rules and
regulations thereunder with respect to transactions in securities of the
Company;

(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
report and timely file such report with the U.S. Securities and Exchange
Commission and any stock exchange or similar authority; and

(3)	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 his
discretion.

The undersigned hereby grants to such attorney-in-fact full power and authority
to do and perform each and every act and thing whatsoever requisite, necessary
and 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 her/his 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

The undersigned agrees that such attorney-in-fact may rely entirely on
information furnished orally or in writing by the undersigned to each such

not the transactions reported could be matched with any other transactions for

16(b).

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Form 3, 4 or 5 reports with respect to
the undersigned's holdings of and transactions in securities issued by the
