If a party is prevented from fulfilling its obligations under this Agreement because of such a force majeure event for a period of 120 days or more, the other party may at any time thereafter terminate this Agreement by written notice to the affected party, without any further obligation (except for the obligations surviving termination as provided in Section 13(g)).
