invalidated, set aside, declared or found to be void or voidable or required to
be repaid to the issuer or to any trustee, custodian, receiver, conservator,
master, liquidator or any other person pursuant to any bankruptcy law or

payment would be deemed to not have been paid, and the obligations of the
Borrower in respect thereof would be immediately and automatically revived
without the necessity of any action by the Lenders.
