authority; and
(4)	take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such an attorney-in-fact, may be of benefit
to, in the best interest of, or legally required by, the Foundation, it being

her discretion.
The powers granted above may be exercised by any one of such attorneys-in-fact
acting alone.
The Foundation grants to each such attorney-in-fact full power and authority to

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 Foundation might or could
do if personally present, with full power of substitution or revocation, 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 virtue
hereof, including but not limited to any filing with the SEC of any Schedule or
