Event for the period from and after the occurrence of such Sustainability Recalculation Event, and (B) the provisions of this Agreement shall be interpreted on the basis of the provisions in effect and applied immediately prior to such Sustainability Recalculation Event for a period of not more than 90 days (unless the provisions hereof shall have been amended in accordance herewith or such notice shall have been withdrawn). If, after 90 days following any such notice, the consent of the Borrower, the Administrative Agent, the Sustainability Structuring Agent and the Required Lenders under Section 11.01 has not been obtained, there will cease to be any Sustainability Rate Adjustment and any Sustainability Commitment Fee Adjustment until such time as the parties hereto can agree upon any such adjustments in accordance with the terms hereof, and during such period, no party to this Agreement shall, without the prior written consent of the Administrative Agent, the Sustainability Structuring Agent and the Borrower, make any public or private representations or description of the credit facility described in this Agreement as a sustainability-linked loan.
