      (ii) The sum of all amounts on deposit (or scheduled to be on deposit) in

pursuant to the Indenture will be $ _______________ (the "Shortfall") less than
the aggregate amount of Scheduled Payments due on ________________.

      (iii) The Trust Collateral Agent is making a claim under the Policy for
the Shortfall to be applied to the payment of Scheduled Payments.

      (iv) The Trust Collateral Agent agrees that, following receipt of funds

Financial Security as agent and attorney-in-fact for the Trust Collateral Agent
and each such Holder in any legal proceeding with respect to the Obligations.
The Trust Collateral Agent hereby agrees that, so long as an Insurer Default (as
defined in the Indenture) shall not exist, Financial Security may at any time
during the continuation of any proceeding by or against the Obligor under the
United States Bankruptcy Code or any other applicable bankruptcy, insolvency,
receivership, rehabilitation or similar law (an "Insolvency Proceeding") direct

performance bond pending any such appeal. In addition, the Trust Collateral
Agent hereby agrees that Financial Security shall be subrogated to, and the
Trust Collateral Agent on its behalf and on behalf of each Holder, hereby
delegates and assigns, to the fullest extent permitted by law, the rights of the
Trust Collateral Agent and each Holder in the conduct of any Insolvency
Proceeding, including, without limitation, all rights of any party to an
adversary proceeding or action with respect to any court order issued in
