by such Indemnified Person by reason of gross negligence or willful misconduct
with respect to such acts or omissions.

action, suit or proceeding shall, from time to time, be advanced by the Sponsor

upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified
Person to repay such amount if it shall be determined that the Indemnified
Person is not entitled to be indemnified as authorized in Section 4.3(a).
