on information provided to such Attorney-in-Fact without
independent verification of such information;
	b) Any documents prepared or executed by the

undersigned from responsibility for compliance with the
undersigned's obligations under Section 13 or Section 16 of
the Exchange Act, including, without limitation, the
reporting requirements under Section 13 or Section 16
of the Exchange Act.

	The undersigned hereby grants to the Attorney-in-Fact
full power and authority to do and perform each and every act
and thing requisite, necessary or advisable to be done in
connection with the foregoing, as fully, to all intents and
purposes, as the undersigned might or could do in person, hereby
ratifying and confirming all that the Attorney-in-Fact, or his
or her substitute or substitutes, shall lawfully do or cause
to be done by authority of this Power of Attorney.

	This Power of Attorney shall remain in full force and
effect until the undersigned is no longer required to file
Forms 4 or 5 or Schedules 13D or 13G or Forms 144 with respect
to the undersigned's holdings of and transactions in
securities of the Company, unless earlier revoked by the
undersigned in a signed writing delivered to the
Attorney-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 executed
