--------------------------------------------------------------------------------

Collateral Account") pursuant to the Custody Agreement, and which Treasury

instruct the Custodian to deliver Enhancer Collateral on either the Monthly

Agreement. Agent Lessor shall at all times have a first priority security
interest in the Enhancer Collateral, including all such substituted Enhancer
Collateral, for the benefit of the Secured Parties, free and clear of all other

withdraw any of the Enhancer Collateral from the Enhancer Collateral Account.
Lessee may not direct either Agent or any Participant to apply any of the
Enhancer Collateral to any Obligation, including, without limitation, the
obligation of Lessee to pay any amounts due under the Operative Documents, and
without limiting Lessee's rights to distributions pursuant to clauses fourth and

aggregate value, as of the first day of such month, of the Enhancer Collateral
then subject to the Pledge Agreement and the Custody Agreement. If the Enhancer
Collateral Value on any Enhancer Collateral Valuation Date is less than the
Enhancer Collateral Requirement, Lessee shall, before the close of business on
the last Business Day of the then current month, deliver to the Custodian for
deposit in the Enhancer Collateral Account additional Enhancer Collateral having
an aggregate Enhancer Collateral Value (which Enhancer Collateral Value, except
in the case of any cash, shall be determined on and as of such last Business Day
