of the business of Financial Security Assurance Holdings Ltd. and certain of
its affiliates (including the Company), the Banks have each deemed it to be in
their best interests to release the Guarantor from any and all obligations that

Agreement reflecting such release and eliminating any requirement on the part
of the Company to provide or maintain the Policy (or any substitution therefor

claims they (or any third party claiming rights through such Party) may make
