  Know all men by these presents, that the undersigned hereby appoints
Dominic J. Andreano with full power of substitution, the true and lawful
attorney-in-fact to:

(1)	execute for and on behalf of the undersigned SEC Forms 3, 4, and 5 relating
to the undersigned's interest in the Company's securities, in accordance with
Section 16(a) of the Securities Exchange Act of 1934, as amended, and the rules
thereunder;

(2)	do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete the execution of any such Form 3, 4,
or 5 and the timely filing of such form with the United States Securities and
Exchange Commission and any other appropriate authority; and

(3)	take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of the 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 the 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 the attorney-in-fact may approve in his
discretion.

  The undersigned hereby grants to the above attorney-in-fact full power and
authority to do and perform all 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,
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
above attorney-in-fact, in serving in such capacity at the request of the
undersigned, is not assuming any of the undersigned's responsibilities to comply
with Sections 13(d) or 16 of the Securities Exchange Act of 1937.

  The authority of Dominic J. Andreano under this Power of Attorney shall
continue until the undersigned is no longer required to file Forms 3, 4, or 5

the Company, unless earlier revoked in writing.

  IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
