I got the date from the 8-K.

 by written notice by Buyer or the Sellers’ Representative if any of the conditions to the Closing set forth in ARTICLE VI have not been satisfied or waived by September 30, 2020 (the “Outside Date”); provided, however, the right to terminate this Agreement under this Section 7.1(b) shall not be available to a party if the breach or violation by such party or its Affiliates of any representation, warranty, covenant or obligation under this Agreement was the cause of, or resulted in, the failure of the Closing to occur on or before the Outside Date;
