If a Covered Party or BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regimes if the Supported QFC and Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights

and remedies of the parties with respect to a defaulting lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

Definitions.
