Furthermore, Seller (and any successor) shall self report to Purchaser at any time during any calendar year if its [REDACTED] falls below the minimum limits for such calendar year as required pursuant to this Section 2. The failure of Seller (and any successor) to comply with the provisions of this Section 2, shall hereinafter be referred to as a “Seller Triggering Event.”

(c) Purchaser (and any successor thereto by way of merger, consolidation, sale or divestiture) covenants and agrees to deliver to Seller (and any successor) Purchaser’s (and any successor’s) annual consolidated financial statements as soon as practicable and in any event within 90 days after the end of each fiscal year, all in reasonable detail and certified by an authorized financial officer of Purchaser (or any successor, if applicable). Furthermore, Purchaser (and any successor) shall self report to Seller (and any successor) at any time during any calendar year if Purchaser’s (and any successor’s) [REDACTED] falls below [REDACTED]. For purposes of this Agreement, a “Purchaser Triggering Event” shall mean (i) the failure of Purchaser (and any successor) to maintain an [REDACTED], (ii) the failure of Purchaser (and any successor) to self report its failure to maintain such [REDACTED] as provided by the preceding sentence and/or (iii) the failure of Purchaser (and any successor) to deliver its annual consolidated financial statements in accordance with the provisions of this Section 2.
