 4

Default shall occur and be continuing, on the Business Day that Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Revolving Lenders with LC Exposure representing

maturity of the Loans has been accelerated (but subject to the consent of Revolving Lenders with LC Exposure representing greater than 50% of the total LC Exposure), be applied to satisfy other Obligations of Borrower under this Agreement. If
Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount plus any accrued interest or realized profits with respect to such amounts (to the extent not applied as
aforesaid) shall be returned to Borrower within three Business Days after all Events of Default have been cured or waived.”
