        necessary or desirable to complete and execute any such Schedule 13D,
        Schedule 13G, Form 3, Form 4 and Form 5, or any amendment thereto, and
        to timely file such schedule, form or amendment thereto with the United
        States Securities and Exchange Commission (the "SEC") and any stock
        exchange or similar authority; and

fully to all intents and purposes as I might or could do if personally present,
