attorney-in-fact to:

        1.  complete and execute Forms ID, 3,4 and 5 and other forms and all
            amendments thereto as such attorney-in-fact shall in his or her
            discretion determine to be required or advisable pursuant to Section
            16 of the Securities Exchange Act of 1934 (as amended) and the rules
            and regulations promulgated thereunder, or any successor laws and
