conduct does not constitute the sort of behavior that would preclude his
indemnification under this Article VII and Executive furnishes the Company a
written undertaking, executed personally or on his behalf, to repay any advances
if it is ultimately determined that he is not entitled to be indemnified by the
Company under this Article VII.

agreement, any vote of shareholders or disinterested directors, Bermuda law, any
other law (common or statutory) or otherwise. Nothing contained in this Article
VII shall be deemed to prohibit the Company from purchasing and maintaining
insurance, at its expense, to protect itself or Executive against any expense,
liability or loss incurred by it or him, whether or not Executive would be
indemnified against such expense, liability or loss under this Article VII;
provided that the Company shall not be liable under this Article VII to make any
payment of amounts otherwise indemnifiable hereunder if and to the extent that
Executive has otherwise actually received such payment under any insurance
policy, contract, agreement or otherwise. In the event the Company makes any
indemnification payments to Executive and Executive is subsequently reimbursed
from the proceeds of insurance, Executive shall promptly refund such
indemnification payments to the Company to the extent of such insurance
reimbursement.
