     8. The Sponsor agrees, to the fullest extent permitted by applicable law,

     (a) to indemnify and hold harmless the Fiduciary Indemnified Person, or any
of its officers, directors, shareholders, employees, representatives or agents,
from and against any loss, damage, liability, tax, penalty, expense or claim of
any kind or nature whatsoever incurred by the Fiduciary Indemnified Person by
