If a Force Majeure Event occurs prior to the Provisional In-Service Date that results or will result in a delay in achieving that Project Milestone, then, immediately after the giving of the notice required under Section 14.2.1, the Project Milestone Schedule shall be equitably adjusted upon the written agreement of the Parties. If the Parties are unable to agree on an equitable adjustment to the Required Provisional In-Service Date or other affected Project Milestones within a period of sixty (60) Days after the giving of the notice required in Section 14.2.1, such inability to agree shall be considered a Dispute and either Party thereafter shall be entitled to bring such Dispute to arbitration in accordance with this Agreement.
