18.2 Right To Terminate This Settlement Agreement
In the event that: (i) the Stipulation of Settlement, the Final Order and Judgment, and/or any order proposed jointly by the Parties relating thereto, are not approved by the Court substantially in the form submitted; (ii) the Company does not enter into the OAG Assurance of Discontinuance containing terms substantially the same as those detailed in Section 4 of this Settlement Agreement; (iii) Defendants opt to terminate the Settlement pursuant to Section 14.2; or (iv) approval of the Stipulation of Settlement, the Final Order and Judgment, and/or such orders, are modified or reversed in any material respect by any appellate or other court (each being a Termination Event), the Parties that are adversely affected by the Termination Event shall have the right, in their sole and absolute discretion, to terminate this Settlement Agreement by providing written notice to Settlement Class Counsel or Defendants counsel, as applicable, within twenty (20) days after the Termination Event. If the Settlement Agreement is so terminated, this Stipulation, the Final Order and Judgment, and all orders entered in connection with it shall become null and void and of no further force and effect with respect to Settling Plaintiffs, Defendants, and the Settlement Class. In the event of any Termination Event, the Parties shall be restored to their original positions, except as expressly provided herein.
