Unless excused, Contractor shall promptly commence performance of such unilateral Change Order work, the impacts of such unilateral Change Order shall be reflected in Contractor’s deliverables specified in Article II.3.M, and Company shall compensate Contractor in accordance with Article III. Contractor shall be excused from performing unilateral Change Order work that (i) is outside the limits of Company’s ability to issue a unilateral Change Order as described in this Article II.5.B.1).b., or (ii) in Contractor’s reasonable good faith belief, is not within the scope of the Company identified nuclear liability protections in Article V.4.

If multiple unfunded unilateral Change Orders are issued, Company Representative or another duly authorized representative of Company may direct in writing the priority of Contractor’s performance of unilateral Change Order work under the aforementioned cap. If (ii) is invoked and Contractor incurs based on unilateral Change Orders in two consecutive months, then Company will add a continuing balance, on an indefinite basis and in excess of amounts requested by Contractor in accordance with Exhibit 3, of going forward unless otherwise agreed by the Parties in writing. 2) Contractor Initiated Change Orders. Contractor may initiate the bilateral Change Order process by advising Company in writing that in Contractor’s opinion an alteration of or addition to the scope of Facilities or Services is necessary.

Company shall advise Contractor in writing of its agreement or disagreement within ten (10) days. If Company agrees, it shall advise Contractor in writing and, thereafter, the Change Order process shall be handled as if initiated by Company. C. Changes. Changes to the then-agreed cost and schedule baseline shall be managed and approved through an agreed Change Management Process. Changes, and an agreed Change Management Process, shall be used solely to address cost and schedule trends, and shall not be applied to require Contractor to complete any particular services for a set price or schedule; Contractor shall be entitled to changes to address increases in Contractor’s costs or the estimated time for completion of the Services. D. Disputed Change Orders or Changes. 1) Disputed Change Orders. If a Party disputes the existence, extent, validity, or effect of a Change Order or Change Order request, then the Party may notify the other Party that it desires to meet and resolve the dispute. If the dispute cannot be resolved to the mutual satisfaction of the Parties within ten (10) days, then the Parties shall proceed to resolve the dispute in accordance with Article XIII. 2) Disputed Changes. If a Party believes a Change is properly a Change Order or disputes the existence, extent, validity, or effect of a Change, then the Party may notify the other Party that it desires to meet and resolve the dispute. If the dispute cannot be resolved to the mutual satisfaction of the Parties within ten (10) days, then the Parties shall proceed to resolve the dispute in accordance with Article XIII. III. Compensation 1. Company shall compensate and pay Contractor for the Services in accordance with this Article III and Exhibit 3 (Compensation and Payment). 2. Notwithstanding anything to the contrary in this Agreement or Exhibit 3, (a) undisputed amounts owed by Contractor to Company, including without limitation for undisputed overpayments and undisputed duplicate payments, or (b) amounts owed by Contractor to Company to satisfy warranty obligations (subject to Section XIV.7.F) shall be, at Contractor’s election, either (i) promptly paid by Contractor to Company, or (ii) offset by Company against amounts due Contractor. 3.

Nothing in this clause precludes or restricts Company from exercising its audit rights under this Agreement or from questioning or disputing amounts paid to Contractor. Any Company exercise of offset in accordance with the requirements of this Article III shall not be grounds for Contractor to suspend, terminate, or cancel performance. IV. Warranties 1.
