          regulation of the SEC;

     2.   execute for and on behalf of the undersigned, Forms 3, 4, and 5 in

     3.   do and perform any and all acts for and on behalf of the undersigned

          thereto, and timely file such form with the SEC and any stock exchange
          or similar authority; 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-

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 and
resubstitution or revocation, hereby ratifying and confirming all that such
attorney-in-fact, or such attorneys-in-fact substitute or substitutes, shall

foregoing attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are not assuming, nor is any Company assuming, any of the
undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934, as amended. This Power of Attorney shall remain in full
force and effect until the undersigned is no longer required to file Forms 3, 4,
