                undersigned which may be necessary or desirable to complete and
                execute any such Form 3, Form 4, Form 5 or Form 144 and timely
                file such form with the United States Securities and Exchange
                Commission and any stock exchange or similar authority; and

        3.      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-fact's
                discretion.

        The undersigned hereby grants 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 or revocation,
hereby ratifying and confirming all that such attorney-in-fact shall lawfully do
or cause to be done by virtue of this power of attorney and the rights and
powers herein granted. The undersigned acknowledges that the foregoing
attorney-in-fact, in serving in such capacity at the request of the undersigned,
is not assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16(a) of the Securities Exchange Act of
1934 or Rule 144 of the Securities Act of 1933.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer an officer of the Company unless earlier revoked by the
undersigned in a signed writing delivered to the foregoing attorneys-in-fact;
provided, however, this Power of Attorney will expire immediately upon the
termination of employment or consulting arrangement of any attorney-in-fact as
to that attorney-in-fact only, but not as to any other appointed
attorney-in-fact hereunder.

        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of this 9 day of January, 2007.
