The written statement shall be in the form of Schedule D-3, and shall include, to the extent practicable, all information required by Section 6.5B. Owner shall respond to Contractor’s written statement within fourteen (14) Business Days of receipt, responding to Contractor’s statement as to the effects of the proposed Change Order on the Changed Criteria. If it is not practicable for Contractor to provide all of the information required under this Section 6.1A to be submitted with such written statement within such thirty (30) Day period, Contractor shall provide Owner with as much information as practicable as well as a written explanation of the reason additional time is required. To the extent Contractor incurs costs exceeding Thirty Thousand U.S. Dollars (U.S.$30,000) (which costs shall be adequately documented and supported by Contractor) in responding to any one proposed Change Order, Contractor shall be reimbursed for such excess costs in responding to such Change Order within twenty-five (25) Days after Owner’s receipt of Contractor’s invoice therefor; provided that Contractor first gives Owner written notice of the estimate of the cost of such preparation before preparing the response, such estimate is in excess of Thirty Thousand U.S. Dollars (U.S.$30,000), Owner approves in writing the preparation of the response, and such proposed Change Order is not implemented. B. If the Parties agree on such Changed Criteria of the proposed Change Order (or modify such proposed Change Order so that the Parties agree on such Changed Criteria), the Parties shall execute such Change Order incorporating the Changed Criteria, which shall be in the form of Schedule D-1, and such Change Order shall become binding on the Parties, as part of this Agreement. C. If the Parties cannot agree on such Changed Criteria of the proposed Change Order within ten (10) Days of Contractor’s receipt of Owner’s response to Contractor’s written statement, or if Owner desires that the proposed changed Work set forth in the proposed Change Order commence immediately without the requirement of a written statement by Contractor as required under Section 6.1A, Owner may (subject to this Section 6.1C), by issuance of a unilateral Change Order in the form attached hereto as Schedule D-2, require Contractor to commence and perform the changed Work specified in the unilateral Change Order on a time and material basis as set forth in Schedule D-4 with the effect of such unilateral Change Order on the Changed Criteria (or if the Parties agree on the effect of such unilateral Change Order for some but not all of the Changed Criteria, the impact of each of the components of the Changed Criteria on which the Parties disagree) to be determined as soon as possible but without prejudice to Contractor’s right to refer any Dispute for resolution in accordance with Article 18. The rates specified in Schedule D-4 are “Unit Rates,” and the Unit Rates shall be used to the extent applicable to the changed Work. The Parties acknowledge and agree that unilateral Change Orders submitted by Owner in accordance with this Section 6.1C shall be limited to additions or modifications to, or deductions from the Work and that Owner shall not have the unilateral right to change, amend or modify any of the other Changed Criteria or the terms of this Agreement. Pending resolution of the Dispute, Contractor shall perform the Work as specified in such unilateral Change Order and Owner shall continue to pay Contractor in accordance with the terms of this Agreement and any previously agreed Change Orders. When Owner and Contractor agree on the effect of such unilateral Change Order on all of the Changed Criteria, such agreement shall be recorded by execution by the Parties of a Change Order in the form attached hereto as Schedule D-1, which shall supersede the unilateral Change Order previously issued and relating to such changed Work. With the exception of any Contract Price adjustment contemplated under Attachment EE, in no event shall Owner be entitled to issue any unilateral Change Order in accordance with this Section 6.1C where such unilateral Change Order (i) would result in an increase equal to or exceeding Twenty Million U.S. Dollars (U.S.$20,000,000), or (ii) in conjunction with other unilateral Change Orders issued by Owner (other than any Contract Price adjustment contemplated under Attachment EE), would in themselves result in an increase equal to or exceeding an amount equal to Sixty Million U.S. Dollars (U.S.$60,000,000); provided that, with respect to unilateral Change Orders requiring Contractor to conduct or develop engineering studies, Contractor shall not be required to incur costs (a) greater than Thirty Thousand U.S. Dollars (U.S.$30,000) for any single Change Order for engineering studies, or (b) in conjunction with other unilateral Change Orders, greater than Three Hundred Thousand (U.S.$300,000) in the aggregate for engineering studies. Notwithstanding the foregoing, in no event shall Owner be entitled to issue any unilateral Change Order directing performance of Work under an LNTP. For the avoidance of doubt, the Parties agree that the adjustments contemplated under Attachment EE do not constitute unilateral Change Orders. D. In the event of a change in any Applicable Code and Standard which does not constitute a Change in Law, Contractor shall provide written notice to Owner regarding such change. Upon receipt of such notice from Contractor, Owner may submit a proposed Change Order to Contractor in accordance with this Section 6.1 in the event Owner, at its sole option, elects for Contractor to implement such change in Applicable Code and Standard. In the event Owner does not, at its sole option, elect for Contractor to implement such change in Applicable Code and Standard, Contractor shall not be required to perform in accordance with such Applicable Code and Standard. In the event, however, that compliance with such Applicable Code and Standard is mandatory for Contractor to comply with GECP and Owner does not, at its sole option, after receipt of written notice from Contractor regarding same, elect for Contractor to implement such change in Applicable Code and Standard, then Owner waives its rights to claim a breach of GECP with respect to such change in Applicable Code and Standard.

In the event Owner does not, at its sole option, elect for Contractor to implement such change in Applicable Code and Standard, Contractor shall not be required to perform in accordance with such Applicable Code and Standard. In the event, however, that compliance with such Applicable Code and Standard is mandatory for Contractor to comply with GECP and Owner does not, at its sole option, after receipt of written notice from Contractor regarding same, elect for Contractor to implement such change in Applicable Code and Standard, then Owner waives its rights to claim a breach of GECP with respect to such change in Applicable Code and Standard.
