(2)   seek or obtain, as the undersigned's representative and on the

The undersigned acknowledges that:

(1)   this Power of Attorney authorizes, but does not require, such
      attorney-in-fact to act in his or her discretion on information provided
      to such attorney-in-fact without independent verification of such
      information;

      behalf of the undersigned pursuant to this Power of Attorney will be in
      such form and will contain such information and disclosure as such
      attorney-in-fact, in his or her discretion, deems necessary or desirable;

(3)   neither the Company nor such attorney-in-fact assumes (i) any
      liability for the undersigned's responsibility to comply with the
      requirements of Section 16 of the Exchange Act, (ii) any liability of the
      undersigned for any failure to comply with such requirements, or (iii) any
      obligation or liability of the undersigned for profit disgorgement under
      Section 16(b) of the Exchange Act; and

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

The undersigned hereby gives and grants the foregoing attorneys-in-fact, and
each of them, full power and authority to do and perform any and every act and
thing whatsoever requisite, necessary or appropriate to be done in and about the
foregoing matters as fully to all intents and purposes as the undersigned might
or could do if present, with full power of substitution and re-substitution,
hereby ratifying and confirming all that such 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 reports (including Forms 3, 4 and 5)
under Section 16 of the Exchange Act with respect to the undersigned's
transactions in equity securities of the Company, unless earlier revoked by the
undersigned in a signed writing delivered to such attorney-in-fact.
