The Parent Guarantor and the Borrower consent to the foregoing and agree, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Parent Guarantor or the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Parent Guarantor or the Borrower in the amount of such participation.”

Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Parent Guarantor, the Borrower and the Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Parent Guarantor, the Borrower and such Restricted Subsidiaries.”
