RELATIONSHIP OF OWNER, CONTRACTOR AND SUBCONTRACTORS

2.1 Status of Contractor. The relationship of Contractor to Owner shall be that of an independent contractor. Any provisions of this Agreement which may appear to give Owner or the Owner Representative the right to direct or control Contractor as to details of performing the Work, or to exercise any measure of control over the Work, shall be deemed to mean that Contractor shall follow the desires of Owner or the Owner Representative in the results of the

Work only and not in the means by which the Work is to be accomplished, and Contractor shall have the complete right, obligation and authoritative control over the Work as to the manner, means or details as to how to perform the Work. Nothing herein shall be interpreted to create a master-servant or principal-agent relationship between Contractor, or any of its Subcontractors or Sub-subcontractors, and Owner. Nevertheless, Contractor shall strictly comply with all provisions, terms and conditions of this Agreement, and the fact that Contractor is an independent contractor does not relieve it from its responsibility to fully, completely, timely and safely perform the Work in strict compliance with this Agreement.

2.2 Key Personnel, Organization Chart and Contractor Representative.

A. Key Personnel and Organization Chart. Attachment F sets forth Contractor’s organizational chart to be implemented for the Work and also contains a list of key personnel (“Key Personnel” or “Key Persons”) from Contractor’s organization who will be assigned to the Work. Owner and Contractor acknowledge and agree the continuity of Key Personnel during the performance of the Work is a material requirement of this Agreement and that replacement of a Key Person may be detrimental to the Owner and the overall quality of the Work. Key Personnel shall, unless otherwise expressly stated in Attachment F, be devoted essentially full-time to the Work for the entire duration of the Work, and Key Personnel shall not be removed or reassigned without Owner’s prior written approval, which shall not be unreasonably withheld. All requests for the substitution of Key Personnel shall include a detailed explanation and reason for the request and the resumes of professional education and experience for one or more substitute candidates for Owner’s approval (such approval not to be unreasonably withheld). The additional cost of any replacement of such Key Personnel and any overlap time during the transition from one Key Person to another shall be entirely at Contractor’s expense. Owner has the right, but not the obligation, to require Contractor to remove or cause to be removed a Key Person who is not, in Owner’s reasonable judgment, acting safely and reasonably in the performance of the portion of the Work assigned to such Key Person.

B. Contractor Representative. Contractor designates *** as the Contractor Representative. Notification of a change in Contractor Representative shall be provided in advance, in writing, to Owner. The Contractor Representative is a Key Person.

2.3 Subcontractors and Sub-subcontractors. Owner acknowledges and agrees that Contractor intends to have portions of the Work accomplished by Subcontractors pursuant to written Subcontracts between Contractor and such Subcontractors, and that such Subcontractors may have certain portions of the Work performed by Sub-subcontractors. All Subcontractors and Sub-subcontractors shall be reputable, qualified firms with an established record of successful performance in their respective trades performing identical or substantially similar work. NO SUBCONTRACTOR OR SUB-SUBCONTRACTOR IS INTENDED TO BE OR SHALL BE DEEMED A THIRD-PARTY BENEFICIARY OF THIS AGREEMENT. Contractor shall be fully responsible to Owner for the acts and omissions of Subcontractors and Sub-subcontractors and of Persons directly or indirectly employed by any of them, as Contractor is for the acts or omissions of Persons directly employed by Contractor. All Subcontractors and Sub-subcontractors and their respective personnel are to be instructed by Contractor in the terms and requirements of Owner-approved

safety and environmental protection policies and procedures and shall be expected to comply with such policies and procedures. In the event that any personnel do not adhere to such policies and procedures, such personnel shall be removed by Contractor. In no event shall Contractor be entitled to any adjustment of the Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date or the Required Final Completion Date as a result of compliance with such policies and procedures or any removal of personnel necessitated by non-compliance. Nothing contained herein shall (i) create any contractual relationship between any Subcontractor and Owner, or between any Sub-subcontractor and Owner, or (ii) obligate Owner to pay or cause the payment of any amounts to any Subcontractor or Sub-subcontractor.

2.4 Subcontracts and Sub-subcontracts.

A. Approved List. Attachment G sets forth a list of Subcontractors and Sub-subcontractors that Contractor and Owner have agreed are approved Subcontractors and Sub-subcontractors for the performance of that portion of the Work specified in Attachment G. Approval by Owner of any Subcontractors or Sub-subcontractors (either as set forth in Attachment G, pursuant to this Section 2.4 or otherwise) does not relieve Contractor of any responsibilities under this Agreement.

B. Additional Proposed Major Subcontractors and Major Sub-subcontractors. In the event that Contractor is considering the selection of a Subcontractor or Sub-subcontractor not listed on Attachment G that would qualify as a Major Subcontractor or Major Sub-subcontractor, Contractor shall (i) notify Owner of its proposed Major Subcontractor or Major Sub-subcontractor as soon as possible during the selection process and furnish to Owner all information reasonably requested by Owner with respect to Contractor’s selection criteria, and (ii) notify Owner no less than fifteen (15) Days prior to the execution of a Major Subcontract with a Major Subcontractor or Major Sub-subcontract with a Major Sub-subcontractor not listed on Attachment G. Owner shall have the discretion, not to be unreasonably exercised, to reject any proposed Major Subcontractor or Major Sub-subcontractor not listed on Attachment G for a Major Subcontract or Major Sub-subcontract. Contractor shall not enter into any Major Subcontract with a proposed Major Subcontractor or Major Sub-subcontract with a Major Sub-subcontractor that is rejected by Owner in accordance with the preceding sentence. Owner shall undertake in good faith to review the information provided by Contractor pursuant to this Section 2.4B expeditiously and shall notify Contractor of its decision to accept or reject a proposed Major Subcontractor or Major Sub-subcontractor as soon as practicable after such decision is made. Failure of Owner to accept a proposed Major Subcontractor or Major Sub-subcontractor within fifteen (15) Days after Owner’s receipt of the notice to be provided by Contractor as set forth above shall be deemed to be an acceptance of such Major Subcontractor or Major Sub-subcontractor. For purposes of clarity, Owner’s approval shall not be required for the selection or replacement of a Subcontractor or Sub-subcontractor that is not a Major Subcontractor or Major Sub-subcontractor.

C. Other Additional Proposed Subcontractors and Sub-subcontractors. For any Subcontractor not covered by Sections 2.4A or 2.4B, Contractor shall, within thirty (30) Days prior to the selection of any such Subcontractor, notify Owner in writing of the

selection of such Subcontractor and inform Owner generally what portion of the Work such Subcontractor is performing.

D. Delivery of Major Subcontracts. Contractor shall furnish Owner with a copy of all Subcontracts within ten (10) Days after Owner’s written request. Contractor may deliver such Subcontracts with the pricing information redacted therefrom. Notwithstanding the above, Owner’s receipt and review of any Subcontracts shall not relieve the Contractor of any obligations under this Agreement nor shall such action constitute a waiver of any right or duty afforded Owner under this Agreement or approval of or acquiescence in a breach hereunder.

E. Terms of Major Subcontracts and Major Sub-subcontracts. In addition to the requirements in Section 2.3 and without in any way relieving Contractor of its full responsibility to Owner for the acts and omissions of Subcontractors and Sub-subcontractors, Contractor shall:

1. include in each Major Subcontract and Major Sub-subcontract, a provision that each such Major Subcontract and Major Sub-subcontract may be assigned to Owner without the consent of the respective Major Subcontractor or Major Sub-subcontractor upon termination of this Agreement; and

2. use reasonable commercial efforts to include in each Major Subcontract and Major Sub-subcontract a provision requiring each such Major Subcontractor and Major Sub-subcontractor to comply with and perform for the benefit of Owner all requirements and obligations of Contractor to Owner under this Agreement, as such requirements and obligations are applicable to the performance of the work under the respective Major Subcontract or Major Sub-subcontract; provided, however, at a minimum, Contractor shall include in each Major Subcontract and Major Sub-subcontract (except for Major Sub-subcontracts for the supply of bulk materials or commodities), for the benefit of Owner, provisions substantially similar to the following provisions set forth in this Agreement: Article 11, and Sections 3.16, 9.1, and 22.11.

2.5 Contractor Acknowledgements.

A. The Agreement. Prior to the execution of this Agreement, Contractor performed engineering, cost estimating and related services and developed and provided the information that forms the Scope of Work and Design Basis listed in Attachment A, which was performed pursuant to the MOU. Owner has relied upon Contractor’s expertise in developing and providing such information. Contractor hereby represents that such information and the attached Scope of Work and the Design Basis in Attachment A are accurate, adequate and complete to engineer, procure, construct, pre-commission, commission, start-up and test a fully operational natural gas-fired power generation facility for the Contract Price, within the required times set forth by the Key Milestone Schedule, the Guaranteed Substantial Completion Date and Required Final Completion Date, and in accordance with all requirements of this Agreement, including Applicable Codes and

Standards, Applicable Law, the Warranties, Minimum Acceptance Criteria and Performance Guarantees, and that with respect to any information (if any) not so developed or provided by Contractor, Contractor has examined all such information and has determined that it is accurate, adequate and complete. Accordingly, Contractor (i) hereby agrees that it shall have no right to claim or seek an increase in the Contract Price or an adjustment to the Key Milestone Schedule, Guaranteed Substantial Completion Date or Required Final Completion Date with respect to any incomplete, inaccurate or inadequate information or requirements that may be contained or referenced in Attachment A, and (ii) hereby waives and releases Owner from and against such claims. Owner makes no guaranty or warranty, express or implied, as to the accuracy, adequacy or completeness of any such information that is contained or referenced in Attachment A.

B. Conditions of the Site. Except as expressly provided for in this Section 2.5B.1, Contractor further agrees and acknowledges that it has made all investigations and inspections that it deems necessary to perform the Work in accordance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date, and understands the climate, terrain and other difficulties that it may encounter in performing the Work in accordance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and Required Final Completion Date. Contractor warrants that it has the experience, resources, qualifications and capabilities at its disposal to perform the Work in accordance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date. Except as expressly provided for in Sections 2.5B.1, 6.2A.5, and 6.2A.6, Contractor assumes all risks related to, and waives any right to claim an adjustment in the Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date or the Required Final Completion Date in respect of, any failure to timely perform the Work in accordance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date as a result of any conditions at the Site or at any other location where the Work is performed (excluding Force Majeure events), including assuming all risk and waiving all rights with respect to: (i) river levels, topography and subsurface conditions; (ii) climatic conditions, tides, and seasons; (iii) availability of laborers, Subcontractors, Sub-subcontractors, equipment or any other items or supplies; (iv) adequate availability and transportation of Equipment; and (v) breakdown or other failure of equipment under the control of or provided by Contractor or its Subcontractors or Sub-subcontractors.

1. The Contract Price included herein is based on the subsurface soil report titled “Geotechnical Data Report, Geotechnical Investigation, Contra Costa Power Plant Unit 8 Project, Contra Costa County, California,” dated May 25, 2001 (“Soil Report”), which is based on a site near the Site. A final geotechnical study will be performed at the Site by, or on behalf of, Contractor (which will include testing of the subsurface under the existing structures at the Site), and a report will be generated from such study by or on behalf of Contractor and based upon Contractor’s specifications (the “Final Geotechnical Report”) prior to Owner’s issuance of the Demolition LNTP. If the subsurface conditions as shown by the Final Geotechnical Report are materially different from the Soil Report, the Contract Price shall be adjusted up or down pursuant to a Change Order to the

extent the different subsurface conditions require additional work or reduce work. Contractor’s relief for any material differences between the Soil Report and the Final Geotechnical Report shall be limited to an adjustment in the Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date; provided, however, Contractor shall use best efforts to prevent any extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date as a result of such differences. The Parties agree that only significant differences in subsurface conditions that would cause a major change in the manner, means or methods of constructing the foundations would require an extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, but mere changes in the number or type of piles would not entitle Contractor to such an extension. After the Final Geotechnical Report is issued, and the Contract Price, Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date is adjusted (if and to the extent allowed under this Section 2.5B.1), Contractor shall assume all subsurface risks at the Site, except for unknown underground utilities, manmade subsurface obstructions, rocks that require blasting, sinkholes and archeological finds as further provided for in Section 6.2A.5.

C. Applicable Law and Applicable Codes and Standards.

1. Subject to Section 2.5C.2. Contractor has investigated to its satisfaction Applicable Law and Applicable Codes and Standards and warrants that it can perform the Work at the Contract Price and within the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date in accordance with Applicable Law and Applicable Codes and Standards.

2. If a Change in Law occurs, Contractor shall perform the Work in accordance with such Change in Law and shall be entitled to a Change Order for such Change in Law to the extent allowed under Section 6.2A.1.

The reviews

may be of progress prints, computer images, draft documents, working calculations, draft specifications or reports, Drawings, Specifications or other design documents as reasonably determined by Owner.

2. Submission by Contractor. Contractor shall submit copies of the Drawings and Specifications to Owner for formal review, comment, disapproval and approval in accordance with Attachment B.

3. Review Periods. Owner shall have up to fifteen (15) Days from its receipt of Drawings and Specifications submitted in accordance with Section 3.3C.2 to issue written comments, proposed changes and/or written approvals or disapprovals of the submission of such Drawings and Specifications to Owner; provided, however, with respect to those Drawings and Specifications identified in Attachment B as being time sensitive, Owner shall provide its comments, approvals or disapprovals within ten (10) Days after receipt.

4. No Owner Response. If Owner does not issue any comments, proposed changes or written approvals or disapprovals within such time periods, Contractor may proceed with the development of such Drawings and Specifications and any construction relating thereto, and such lack of Owner response shall be treated as an approval of the Drawings and Specifications in accordance with the terms of Section 3.3C.6

5. Disapproval by Owner. In the event that Owner disapproves the Drawings or Specifications, Owner shall provide Contractor with a written statement of the reasons for such rejection within the time period required for Owner’s response for disapproval of Drawings and Specifications. Contractor shall provide Owner with revised and corrected Drawings and Specifications as soon as possible thereafter and Owner’s rights with respect to the issuing of comments, proposed changes or approvals or disapprovals of such revised and corrected Drawings or Specifications are governed by the procedures specified above in this Section 3.3C; provided that Contractor shall not be entitled to any extensions of time to the Key Milestone Schedule, Guaranteed Substantial Completion Date or Required Final Completion Date, an adjustment to the Contract Price or any adjustment to any other Changed Criteria.

6. Approval by Owner. Upon Owner’s written approval of the Drawings and Specifications, such Drawings and Specifications shall be the Drawings and Specifications that Contractor shall use to construct the Work; provided that Owner’s review, comment or approval of any Drawings and Specifications shall not in any way be deemed to limit or in any way alter Contractor’s responsibility to perform and complete the Work in strict accordance with the requirements of this Agreement, and in the event that there is a discrepancy, difference or ambiguity between the terms of this Agreement and any Drawings and Specifications, the interpretation imposing the greater obligation on Contractor shall control. Due to the limited time for

Owner’s review of Drawings and Specifications, Contractor’s or its Subcontractors’ or Sub-subcontractors’ expertise in the Work and Owner’s reliance on Contractor to prepare accurate and complete Drawings and Specifications, Contractor recognizes and agrees that Owner is not required or expected to make detailed reviews of Drawings and Specifications, but instead Owner’s review of Drawings and Specifications may be of only a general, cursory nature. Accordingly, any review, comment or approval given by Owner under this Agreement with respect to any Drawings or Specifications shall not in any way be, or deemed to be, an approval of any Work, Drawings or Specifications not meeting the requirements of this Agreement, as Contractor has the sole responsibility for performing the Work in accordance with this Agreement.

D. Design Licenses. Contractor shall perform all design and engineering Work in accordance with Applicable Law and Applicable Codes and Standards, and all Drawings, Specifications and design and engineering Work shall be signed and stamped by design professionals licensed in accordance with Applicable Law.

E. CAD Drawings. Unless otherwise expressly provided under this Agreement, all Drawings and Record As-Built Drawings prepared by Contractor or its Subcontractors or Sub-subcontractors under this Agreement shall be prepared using computer aided design (“CAD”). All Record As-Built Drawing files shall be in fully operable and editable AutoCAD.dwg (2005 or later) format; provided, however, the Drawings (including Record As-Built Drawings) prepared by Siemens for the Siemens Equipment shall be provided in the formats required under the Siemens Contract. Contractor shall use commercially reasonable efforts to also provide Drawings, including Record As-Built Drawings, in other formats requested by Owner. All Drawings not Record As-Built Drawings shall utilize Microstation software and shall also be provided in .pdf format.

F. As-Built Drawings and Specifications. During construction, Contractor shall keep a redlined, marked, up-to-date set of Progress As-Built Drawings and Specifications on the Site as required under Attachment B. As a condition precedent to Final Completion, Contractor shall deliver to Owner the Record As-Built Drawings and Specifications in accordance with Attachment B, which shall include delivery of final as-built drawing files in fully operable and editable AutoCAD.dwg (2005 or later) format for Record As-Built Drawings; provided that the Record As-Built Drawings prepared by Siemens for the Siemens Equipment shall be provided in the formats required under the Siemens Contract.

G. Other Information. Contractor shall deliver copies of all other documents required to be delivered pursuant to Attachment B within and in accordance with the requirements and timing set forth in Attachment B.

In consideration of ten and no/100 U.S. Dollars (U.S.$10) incorporated into the Contract Price and as part of the consideration of receiving this Agreement and other valuable consideration received and acknowledged by Contractor, Contractor hereby subordinates any mechanics’ and materialmen’s liens or other claims or encumbrances that may be brought by Contractor against any or all of the Work, the Site or the Facility to any liens granted in favor of Lender, whether such lien in favor of Lender is created, attached or perfected prior to or after any such liens, claims or encumbrances, and shall require its

Subcontractors to similarly subordinate their lien, claim and encumbrance rights. Contractor agrees to comply with reasonable requests of Owner for supporting documentation required by Lender, including any necessary lien subordination agreements, affidavits or other documents that may be required to demonstrate that Owner’s property and premises are free from liens, claims and encumbrances arising out of the furnishing of Work under this Agreement.

3.17 Hazardous Materials. Contractor shall not, nor shall it permit or allow any Subcontractor or Sub-subcontractor to, bring any Hazardous Materials on the Site and shall bear all responsibility and liability for such materials; provided, however, that Contractor may bring onto the Site such Hazardous Materials as are necessary to perform the Work so long as the same is done in compliance with Applicable Law, Applicable Codes and Standards, and the requirements specified in Attachment J, and Contractor shall remain responsible and liable for all such Hazardous Materials. If Contractor or any Subcontractor or Sub-subcontractor encounter pre-existing Hazardous Materials at the Site, and Contractor or any Subcontractor or Sub-subcontractor knows or reasonably should know that such material is Hazardous Material, Contractor and its Subcontractors and Sub-subcontractors shall immediately stop Work in the affected area and notify Owner. If under such circumstances Contractor or any of its Subcontractors or Sub-subcontractors fail to stop Work and notify Owner and through its negligent action exacerbate the circumstances of such pre-existing Hazardous Material, Contractor shall be responsible and liable to Owner in accordance with Section 18.1C for all damages, costs, losses and expenses to the extent relating to such failure.

3.18 Quality Assurance. No later than thirty (30) Days after the date Owner issues NTP, Contractor shall submit to Owner for its review and written approval, a Work-specific quality control and quality assurance plan and an inspection plan, including witness points, shop inspections and shop tests (including those inspections, tests and witness points provided under the Siemens Contract for the Siemens Equipment).

Contractor agrees to coordinate the performance of its Work at the Site with the operation and maintenance of the Mirant

Delta Facility or other Persons activities at or near the Site so as not to interfere with such operations or other Persons performing work at or near the Site.

B. It is the Parties’ intent that the performance of the Work and Contractor’s other obligations under this Agreement will not interfere with the operation of the Mirant Delta Facility, and Contractor shall use its best efforts to coordinate the performance of the Work at the Site with the operation and maintenance of the Mirant Delta Facility so as not to interfere with such operation and maintenance. During the performance of the Work, should a situation arise that has the potential of interfering with the operation of the Mirant Delta Facility, Contractor shall give Owner written notice as soon as possible but no later than seven (7) Days prior to the time that Contractor plans to perform such Work, detailing a plan that describes how such Work will be performed to minimize, to the greatest extent possible, interference with the operation of the Mirant Delta Facility. The plan proposed by Contractor shall be the least disruptive to operations of the Mirant Delta Facility;. Prior to the execution of such Work, Owner, in its discretion (not to be unreasonably withheld), shall approve or disapprove of such plan; provided, however if the agreed upon plan delays pile driving activities which are on the critical path of the CPM Performance Measurement Baseline Schedule or materially increases the costs of such pile driving activities, then Contractor shall be entitled to a Change Order in accordance with Section 6.8.

3.25 Responsibility for Property. Contractor shall plan and conduct its operations so that neither Contractor nor any of its Subcontractors or Sub-subcontractors shall (i) enter upon lands (other than the Site) or waterbodies in their natural state unless authorized by Owner in writing; (ii) close or obstruct any utility installation, highway, waterway, harbor, road or other property unless and until Permits and Owner’s permission therefore have been obtained; (iii) disrupt or otherwise interfere with the operation of any portion of any pipeline, telephone, conduit or electric transmission line, ditch, navigational aid, dock or structure unless otherwise specifically authorized by Owner in writing; (iv) damage any property listed in (ii) or (iii); and (v) damage or destroy maintained, cultivated or planted areas or vegetation such as trees, plants, shrubs, shore protection, paving, or grass on or adjacent to the premises which, as determined by Owner, do not interfere with the performance of this Agreement. The foregoing includes damage arising from performance of the Work through operation of equipment or stockpiling of materials. Contractor shall be fully responsible for all damages, losses, costs and expenses arising out of damage to the Site and shall promptly restore at its own cost and expense the Site to the condition it was in before such damage. Contractor and its Subcontractors and Sub-subcontractors shall coordinate and conduct the performance of the Work so as to not interfere with or disrupt the use and peaceful enjoyment of any adjacent property to the Site.

3.26 Explosives. Explosives shall be transported to the Site only when required to perform the Work under this Agreement and with abundant, prior notice to and written approval of Owner. Contractor shall be responsible for properly purchasing, transporting, storing, safeguarding, handling and using explosives required to perform the Work under this Agreement. Contractor shall employ competent and qualified personnel for the use of explosives and shall assume full responsibility for all costs, losses, damages and expenses caused by the use of explosives. Residual surplus explosives shall be promptly removed from the Site and properly disposed of by Contractor. Contractor shall strictly comply with Applicable Law and Applicable Codes and Standards in the handling of explosives pursuant to this Agreement, shall perform all

obligations and obtain all Permits with respect to explosives, and shall develop and file and provide copies to Owner of all documentation regarding same.

3.27 Nondiscrimination. Contractor agrees that it shall conduct its activities without regard to race, religion, color, sex, gender identity, sexual orientation, national origin, ancestry, citizenship status, uniform service member status, marital status, pregnancy, age, protected medical condition, disability or any other protected status in accordance with all applicable federal, state and local laws.

3.28 Used or Salvaged Materials. If, after Substantial Completion and prior to Final Completion, Contractor has any Equipment that it purchased for the Facility but did not incorporate into the Facility, Owner has the option of either taking such Equipment at a reasonable, market-based cost to Owner or requiring that Contractor haul off such Equipment at Contractor’s own cost and expense; provided, however, if such Equipment was provided by Contractor as part of any Work performed on a time and materials basis, then Owner shall have the right to take such Equipment without paying any further cost to Contractor. Notwithstanding the foregoing, all commissioning spare parts and, to the extent purchased by Owner, operating spare parts shall be the property of Owner.

3.29 Supervision of Owner’s Operation Personnel. Until Substantial Completion, Owner’s operating and maintenance personnel shall be under the control of and supervised by Contractor. To the extent not set forth in Attachment V, Contractor shall, no later than one hundred eighty (180) Days prior to the Guaranteed Substantial Completion Date, prepare for Owner’s review a proposed plan regarding the utilization of Owner’s operation and maintenance personnel and Contractor’s personnel during commissioning and for the conduct of Performance Tests and any other tests. Such plan shall be mutually agreed-upon by the Parties no later than forty-five (45) Days after Owner’s receipt of Contractor’s proposed plan. Without in any way limiting Contractor’s obligation to provide forces and labor during commissioning and Performance Testing, Contractor agrees that if any activity requires direct supervision by Contractor, such activity shall be performed by Contractor or a Subcontractor or Sub-subcontractor. Nothing in this Agreement, including this Section 3.29 or Section 3.2G, shall be interpreted to create a master-servant or principal-agent relationship between Contractor and any of Owner’s operation or maintenance personnel.

3.30 Compliance with Real Property Interests. Contractor shall, in the performance of the Work, comply, and cause all Subcontractors and Sub-subcontractors to comply, with any easement, lease, right-of-way or other property interests that affect or govern the Site or any other real property used for the purposes of completing the Work.

3.31 Compliance with Site Rules. Contractor shall, in the performance of the Work, comply, and cause all Subcontractors and Sub-subcontractors to comply, with any applicable safety, security, and similar work-related policies, procedures, controls and rules which are applicable to the Site, including those imposed by Owner, PG&E, the North American Electric Reliability Corporation, the Western Electricity Coordinating Council or the Federal Energy Regulatory Commission and any Site access rules and procedures.

Owner shall, at no cost to Contractor, provide (i) natural gas at the gas delivery point near the Site meeting or exceeding typical pipeline quality specifications and within the temperature and pressure ranges set forth in Attachment S and (ii) testing power (including back-feed power) for the Facility at the times designated for commissioning and startup of the Facility and conducting the Performance Tests; provided, however, Contractor shall nominate to Owner in writing the natural gas fuel it will require for commissioning, start-up and testing of the Facility at least ten (10) Days in advance of the date upon which such natural gas fuel is required. In addition, Owner shall, at no cost to Contractor, make arrangements to accept the power generated from the Facility during the Performance Tests.

4.8 Utility and Interconnection Studies. Owner shall be responsible for conducting and paying for all utility and interconnection-related system studies.

ARTICLE 5

COMMENCEMENT OF WORK, KEY MILESTONE SCHEDULE, AND SCHEDULING OBLIGATIONS

5.1 Commencement of Work. Upon Contractor’s receipt from Owner of an LNTP or NTP, Contractor shall immediately commence with the performance of the Work specified in such LNTP or NTP.

5.2 Limited Notice to Proceed/Notice to Proceed.

A. Limited Notice to Proceed. At any time prior to the date of issuance of the NTP, Owner may issue an LNTP which shall authorize Contractor to commence performance of a specified portion of the Work. An LNTP shall specify the maximum total cost of such specified Work, and Contractor shall be paid for such specified Work pursuant to the terms and conditions of this Agreement, with all such payments credited against the Contract Price and the first payments to become due hereunder. The LNTP shall be issued in the form attached hereto as Schedule H-1.

B. Limited Notices to Proceed for Siemens. At least thirty (30) Days prior to Owner’s issuance of the GTG LNTP (described below), Owner shall issue to Contractor an LNTP directing Contractor to (i) issue a limited notice to proceed to Siemens under the Siemens Contract so that Siemens can perform certain preliminary engineering work (as contemplated in Section 11.1.1 of the Siemens Contract) for timely delivery of certain document packages pursuant to Appendix 6 of the Siemens Contract and (ii) commence engineering oversight and project management activities related to Siemens’ work in

clause (i) above (collectively, the “Preliminary Engineering LNTP”). Thereafter, and in accordance with the timing requirements established by the Siemens Contract for issuance of full notice to proceed to Siemens under such Siemens Contract, Owner shall issue a LNTP to Contractor directing Contractor to issue a full notice to proceed to Siemens pursuant to the Siemens Contract (such limited notice to proceed issued by Owner to Contractor being the “GTG LNTP”). If Owner fails to issue the GTG LNTP or the Preliminary Engineering LNTP within the time periods established by this Section 5.2B, and as a result thereof Contractor is unable to issue the corresponding limited notice to proceed and full notice to proceed (respectively) to Siemens within the time allowed under the Siemens Contract, then Contractor shall be entitled to an increase to the Contract Price and an extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date by Change Order if and to the extent Siemens is allowed a change to its contract price or schedule under the Siemens Contract; provided that Contractor complies with the Change Order request, notice and mitigation requirements in this Agreement. Notwithstanding anything to the contrary herein, other than payments corresponding to Work performed by Siemens pursuant to the Preliminary Engineering LNTP, Owner shall not be obligated to make any payments to Contractor under this Agreement that correspond to payments to be made by Contractor under the Siemens Contract until Siemens provides a letter of credit to Contractor meeting the requirements set forth in the Siemens Contract.

C. Release for Engineering LNTP. Owner shall issue to Contractor a limited notice to proceed with all remaining engineering Work (including applicable engineering oversight functions) (“Release for Engineering LNTP”) no later than ***. If Owner fails to provide the Release for Engineering LNTP by the foregoing date (or such other date as the Parties may agree upon in writing), then Contractor shall be entitled to a Change Order for the delay associated with such failure in accordance with Section 6.8.

D. Demolition LNTP. Owner shall issue to Contractor a limited notice to proceed with demolition work and the relocation of certain utilities (“Demolition LNTP”) no later than ***. After issuance of the Demolition LNTP, Contractor shall be responsible for the demolition of existing structures at the Site as further set forth in Attachments A and AA. As part of the demolition Work, Contractor shall coordinate with Owner, the Owner-provided environmental remediation contractor and any PG&E representatives involved in remediation efforts to ensure the efficient performance of the demolition Work and any remediation efforts necessary to remediate Hazardous Materials associated with the demolition Work. In addition, Contractor shall also be entitled to a Change Order (to the extent allowed under Article 6) for an adjustment to the Contract Price, Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date to the extent the actual demolition Work to be performed by Contractor materially differs from the information provided in this Agreement or that information that Contractor gathered, or should have gathered, through a visual investigation (using GECP) of the above ground structures to be demolished. In addition, to the extent Owner (or its environmental remediation contractor) fails to timely perform its remediation obligations in accordance with the schedule allowance for such work set out in the Monthly Updated CPM Schedule, Contractor shall be entitled to a Change Order for the delay associated with such failure in accordance with Section 6.8; provided, however, if such failure is due to an

event of Force Majeure, Contractor shall be entitled to a Change Order for such delay in accordance with Section 6.7.

E. Notice to Proceed. Unless otherwise specifically set forth in an LNTP, Contractor shall not commence performance of the Work until Owner issues the NTP authorizing the same pursuant to the terms and conditions of this Agreement. Upon Contractor’s receipt from Owner of the NTP, Contractor shall immediately commence with the performance of the Work specified in such NTP. The NTP shall be issued in the form attached hereto as Schedule H-2.

F. Delay in Issuance of Notice to Proceed. If Owner fails to issue NTP by ***, Contractor shall be entitled to an increase to the Contract Price and an extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, by Change Order if and to the extent Contractor can demonstrate to Owner that receiving the NTP after such date (as compared to on or before such date) has resulted in increased time of performance or costs, on a per-unit basis, for the Work; provided that Contractor complies with the Change Order request, notice and mitigation requirements in Article 6. Conversely, if Owner has not issued NTP by ***, Owner shall be entitled to a decrease to the Contract Price by Change Order if and to the extent it can be demonstrated that receiving the NTP after such date (as compared to on or before such date) has resulted in lower costs, on a per-unit basis, for the Work. Contractor shall use commercially reasonable efforts to assist Owner in identifying lower prices or rates available to Contractor as a result of NTP being issued after *** which would allow a decrease to the Contract Price. The change, if any, in per-unit prices shall be evidenced by Contractor through competitive re-bidding of the per-unit price for the work near the time of issuance of NTP. For the avoidance of doubt, any adjustment to the Contract Price, Key Milestone Schedule, Guaranteed Substantial Completion Date or Required Final Completion Date shall not be based upon a change in quantity of materials or equipment or the amount of labor, engineering or field in-directs.

5.3 Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date. Contractor shall perform the Work in accordance with the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion date set forth in this Section 5.3 and in Attachment E.

A. Key Milestone Schedule. The Key Milestone Dates set forth in the Key Milestone Schedule may only be adjusted by Change Order. Contractor shall be entitled to request a Change Order (which acceptance of such Change Order shall not be unreasonably withheld by Owner and will be subject to the limitations referenced in Section 22.20) in order for Contractor, using GECP, to re-sequence the Work and adjust Key Milestone Dates to improve schedule, efficiency and resource allocation; provided that such changes to the Key Milestone Schedule shall not adjust the Guaranteed Substantial Completion Date. Any Change Order that sets forth an adjustment to any Key Milestone Date or a re-sequencing of the Work pursuant to this Section 5.3A shall also set forth the corresponding update to the CPM Performance Measurement Baseline Schedule.

B. Guaranteed Substantial Completion Date. Contractor shall achieve Substantial Completion no later than *** (“Guaranteed Substantial Completion Date”). The Guaranteed Substantial Completion Date shall only be adjusted by Change Order as provided under this Agreement.

C. Required Final Completion Date. Contractor shall achieve Final Completion no later than *** after achievement of Substantial Completion of the facility (“Required Final Completion Date”); provided however, the requirements set out in clauses (ii), (iv) and (vii) of the definition of Final Completion in Section 1.1 shall be completed by Contractor *** after achievement of Substantial Completion of the facility. The Required Final Completion Date shall only be adjusted by Change Order as provided under this Agreement.

5.4 CPM Schedule.

A. CPM Schedule Submission. Within sixty (60) Days after issuance of the GTG LNTP, Contractor shall prepare and submit to Owner for its review a preliminary critical path method schedule for the Work using Oracle Primavera P6 and showing evidence of the preliminary incorporation of the Siemens engineering deliverable dates within Contractor’s schedule for engineering and construction. Thereafter, Contractor shall submit a detailed critical path method schedule for the Work, for Owner’s review and written approval, no later than one hundred twenty (120) Days after issuance of GTG LNTP which meets the requirements set forth in Attachment U. This detailed critical path method schedule (as well as, for the avoidance of doubt, any CPM Performance Measurement Baseline Schedule and Monthly Updated CPM Schedule) shall adhere to the guidelines set forth in this Section 5.4, including Attachment U.

B. Owner Review of CPM Schedule. Owner may review the detailed critical path method schedule, provided within 120 Days after GTG LNTP pursuant to Section 5.4A, for general conformance with this Agreement, including the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, and issue written comments, proposed changes and/or written approval or disapproval of such critical path method schedule. If Owner reasonably determines that such critical path method schedule does not conform with this Agreement, in any respect, including the Key Milestone Schedule, the Guaranteed Substantial Completion Date or the Required Final Completion Date, Contractor shall revise and resubmit such schedule to Owner within ten (10) Days. Once the critical path method schedule and the required submittals have been reviewed and approved by Owner, this version of the critical path method schedule shall be the baseline critical path method schedule for the Work (the “CPM Performance Measurement Baseline Schedule”). Owner’s review or approval of the CPM Performance Measurement Baseline Schedule (or any updates thereto) shall not relieve Contractor of any obligations for the performance of the Work nor shall it be construed to establish the reasonableness of the CPM Performance Measurement Baseline Schedule. Notwithstanding any approval by Owner of the CPM Performance Measurement Baseline Schedule or any Monthly Updated CPM Schedule, Owner shall be entitled to reasonably rely upon the CPM Performance Measurement Baseline Schedule and any Monthly Updated CPM Schedules, including reliance that Contractor has developed a comprehensive, reasonable and accurate schedule to plan, organize, direct, coordinate, perform, execute and complete each portion of the Work within the times set forth by the

Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date. Contractor shall use the CPM Performance Measurement Baseline Schedule in planning, organizing, directing, coordinating, performing and executing the Work, and the CPM Performance Measurement Baseline Schedule shall be the basis for evaluating progress of the Work.

C. Changes to the CPM Performance Measurement Baseline Schedule. The Contractor shall maintain the CPM Performance Measurement Baseline Schedule which shall contain the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date (as such dates may be adjusted by Change Order in accordance with this Agreement) as well as cost loading data corresponding to the Payment Milestones (as such Payment Milestones may be adjusted by Change Order in accordance with this Agreement). Notwithstanding anything to the contrary in this Agreement, the CPM Performance Measurement Baseline Schedule (including the Key Milestone Schedule, Guaranteed Substantial Completion Date, Required Final Completion Date as well as the cost loading data corresponding to the Payment Milestones) shall only be revised by Change Order executed by both Parties. Within Change Orders executed by the Parties which, due to the nature of the change, necessitate a corresponding modification of the CPM Performance Measurement Baseline Schedule, such modification of the CPM Performance Measurement Baseline Schedule shall be included within such Change Order. This updated CPM Performance Measurement Baseline Schedule shall thereafter be included as the comparison baseline with each Monthly Updated CPM Schedule until the next Change Order (if any) is executed that modifies the CPM Performance Measurement Baseline Schedule again.

D. Monthly Updates to CPM Schedule. After approval by Owner of the CPM Performance Measurement Baseline Schedule, Contractor shall manage and update a critical path method schedule for the Work no less frequently than once per Month to reflect the actual progress to date (“Monthly Updated CPM Schedule”); provided, however, this Monthly Updated CPM Schedule shall not modify the CPM Performance Measurement Baseline Schedule, the Key Milestone Schedule, Guaranteed Substantial Completion Date or Required Final Completion Date, nor shall it change any dates that relate to Owner’s obligations under the Agreement. If Contractor changes the schedule logic, any durations or cost-loading with respect to any activity in its Monthly Updated CPM Schedule such that it deviates from the CPM Performance Measurement Baseline Schedule, Contractor shall provide Owner with a written explanation of each such change along with such Monthly Updated CPM Schedule (but the CPM Performance Measurement Baseline Schedule shall not be changed). The Monthly Updated CPM Schedule shall be statused through the date of the applicable Invoice so that the Work represented in the Monthly Updated CPM Schedule matches the Payment Milestones proposed for payment by Contractor in the Invoice. The Monthly Updated CPM Schedule will have attached to it the current CPM Performance Measurement Baseline Schedule for comparison. The Monthly Updated CPM Schedule shall be in the same detail and form as required by the CPM Performance Measurement Baseline Schedule and shall be submitted by Contractor to Owner with each Invoice. Contractor shall promptly correct any errors or inconsistencies in the updates to the Monthly Updated CPM Schedule identified to Contractor by Owner and resubmit a corrected Monthly Updated CPM Schedule for

Owner’s review. Owner’s review or approval of any Monthly Updated CPM Schedule shall not relieve Contractor of any obligations for the performance of the Work, change the Key Milestone Schedule, the Guaranteed Substantial Completion Date or the Required Final Completion Date, nor shall it be construed to establish the reasonableness of any Monthly Updated CPM Schedule.

E. Form of Submittals. All submittals by Contractor to Owner of the CPM Performance Measurement Baseline Schedule and any Monthly Updated CPM Schedule shall be in both native electronic and paper format. Four (4) hard copies of each submittal shall be provided to Owner, and one (1) electronic copy shall be provided to Owner in a mutually agreeable form. The CPM Performance Measurement Baseline Schedule and Monthly Updated CPM Schedules shall be submitted to Owner with printed reports meeting the requirements set forth in Attachment X.

5.5 Recovery and Recovery Schedule. If, at any time during the prosecution of the Work, should (i) the Monthly Updated CPM Schedule or Monthly Progress Report show that any activity on the critical path of the CPM Performance Measurement Baseline Schedule is delayed such that completion of any Key Milestone, Substantial Completion or Final Completion will occur *** Days after the applicable Key Milestone Date, the Guaranteed Substantial Completion Date or the Required Final Completion Date, respectively, (ii) (a) Contractor fail to provide a Monthly Updated CPM Schedule in compliance with the requirements of this Agreement and (b) Owner notifies Contractor in writing that it has reasonably determined (based upon objective criteria) that the critical path is delayed such that completion of any Key Milestone, Substantial Completion or Final Completion will occur *** Days after the applicable Key Milestone Date, the Guaranteed Substantial Completion Date or the Required Final Completion Date, respectively, or (iii) Contractor fail to complete any Key Milestone, Substantial Completion or Final Completion within *** after the applicable Key Milestone Date, the Guaranteed Substantial Completion Date or the Required Final Completion Date, respectively, then Owner may provide Contractor with a written request for Contractor to prepare a schedule to explain and display how it intends to complete the future Key Milestones, Substantial Completion and Final Completion in accordance with the applicable Key Milestone Dates, the Guaranteed Substantial Completion Date and the Required Final Completion Date (“Recovery Schedule”) as further set forth in this Section 5.5.

A. Within fifteen (15) Days after receipt of Owner’s written request for Contractor to develop a Recovery Schedule, Contractor shall prepare the Recovery Schedule and submit it to Owner for its review. The Recovery Schedule shall represent Contractor’s best judgment as to how it shall complete the remaining Key Milestones, Substantial Completion and Final Completion by the applicable Key Milestone Dates, the Guaranteed Substantial Completion Date and the Required Final Completion Date, respectively. The Recovery Schedule shall be prepared in accordance with GECP and to a similar level of detail as the CPM Performance Measurement Baseline Schedule, and shall be developed for and cover that period of time reasonably necessary to regain compliance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and Required Final Completion Date using all commercially practicable efforts and diligence (including, where effective, establishing additional shifts, hiring additional manpower, working overtime, providing additional equipment, obtaining priority shipments and re-sequencing activities). Within the Recovery Schedule proposed by Contractor, and in

accordance with GECP, Contractor may request (which such request shall not be unreasonably denied by Owner and will be subject to the limitations referenced in Section 22.20) re-sequencing the Work and adjusting the Key Milestone Dates to improve schedule, efficiency and resource allocation; provided that such Recovery Schedule proposal shall not adjust the Guaranteed Substantial Completion Date; provided further that any requested re-sequencing of the Work or requested adjustment to any Key Milestone Date shall be expressly stated in writing by Contractor in a notice to Owner (in addition to being illustrated by the proposed Recovery Schedule).

B. At Owner’s written request after Contractor’s initial submission of the Recovery Schedule, Contractor shall participate in a conference with Owner, and with any other Person, including Subcontractors and Sub-subcontractors, whom Owner designates to participate, to review and evaluate the Recovery Schedule. Any revisions necessary as a result of this review shall be resubmitted for review by Owner within three (3) Business Days after the conference. The revised Recovery Schedule, once agreed upon by Owner in writing, shall then be the schedule which Contractor shall use in planning, organizing, directing, coordinating, performing, and executing the Work (including all activities of Subcontractors and Sub-subcontractors) to regain compliance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date. The agreed upon Recovery Schedule, including any changes to the Key Milestone Dates, shall be incorporated into the CPM Performance Measurement Baseline Schedule by Change Order; provided that the Guaranteed Substantial Completion Date shall not be adjusted by such incorporation of the Recovery Schedule.

C. The cost of preparing and performing in accordance with the Recovery Schedule shall be for Contractor’s account. Owner’s requirement, review and approval of the Recovery Schedule shall not relieve Contractor of any obligations for the performance of the Work, change the Guaranteed Substantial Completion Date or Required Final Completion Date, or be construed to establish the reasonableness of the Recovery Schedule.

5.6 Acceleration and Acceleration Schedule. Even if the Work is otherwise in compliance with the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date, Owner may, at any time, direct Contractor by an Owner-directed or mutually agreed Change Order to accelerate the Work by, among other things, establishing additional shifts, paying or authorizing overtime, providing additional construction equipment or expediting Equipment; provided, however, Owner’s direction to Contractor to accelerate the Work shall be reasonable and in no event shall Owner unilaterally order acceleration of the Work requiring Contractor to achieve Substantial Completion or Final Completion prior to the respectively, original Guaranteed Substantial Completion Date or Required Final Completion Date. In the event of this directive, Owner’s sole liability shall be to pay to Contractor any documented costs attributable to such acceleration. Such costs may include any shift differential, premium, or overtime payments to workers or field supervisors and other employees of Contractor dedicated to the Work on a full-time basis actually incurred over and above Contractor’s normal rates, and overtime charges for equipment and any additional field overhead or expenses resulting from the acceleration directive. Any adjustment to the Contract Price or any other Changed Criteria that the Parties agree will be changed by such acceleration for Owner’s acceleration of the

Work shall be implemented by Change Order. If Owner directs Contractor to accelerate the Work pursuant to a Change Order, Contractor shall immediately commence and diligently perform the acceleration of the Work as directed by Owner, and shall prepare a schedule to explain and display how it intends to accelerate the Work and how that acceleration will affect the critical path of the CPM Performance Measurement Baseline Schedule (the “Acceleration Schedule”). With respect to the Acceleration Schedule, Contractor shall do the following:

A. No later than the fifteenth (15^th) Day after such directive, Contractor shall prepare the Acceleration Schedule and submit it to Owner for its review. The Acceleration Schedule shall represent Contractor’s best judgment as to how it shall satisfy Owner’s acceleration directive. The Acceleration Schedule shall be prepared using GECP and to a similar level of detail as the CPM Performance Measurement Baseline Schedule.

B. On the fifteenth (15^th) Day after such directive (or such longer time as specified in writing by Owner), Contractor shall participate in a conference with Owner, and with any other Person, including Subcontractors and Sub-subcontractors, whom Owner designates to participate, to review and evaluate the Acceleration Schedule. Any revisions to the Acceleration Schedule necessary as a result of this review shall be resubmitted for review by Owner no later than the tenth (10^th) Day of such meeting or such other date as Owner may permit. The revised Acceleration Schedule shall then be the schedule which Contractor shall use in planning, organizing, directing, coordinating, performing, and executing that portion of the Work that is affected by such acceleration, with the CPM Performance Measurement Baseline Schedule governing the performance of all other Work.

Owner’s review and approval of the Acceleration Schedule shall not constitute an independent evaluation or determination by Owner of the workability, feasibility, or reasonableness of that schedule.

ARTICLE 6

CHANGES; FORCE MAJEURE; AND OWNER-CAUSED DELAY

6.1 Change Orders Requested by Owner. Owner shall be entitled to a Change Order upon request in accordance with this Section 6.1.

A. If Owner submits to Contractor in writing a duly signed proposed Change Order, Contractor must respond to Owner within fifteen (15) Days with a written statement setting forth the effect, if any, which such proposed Change Order would have on the Contract Price, the Key Milestone Schedule, the Design Basis, the Guaranteed Substantial Completion Date, the Required Final Completion Date, the Payment Schedule, any of the Minimum Acceptance Criteria or Performance Guarantees, or any other obligation or potential liability of Contractor hereunder (collectively or individually, the “Changed Criteria”). The written statement shall be in the form of Schedule D-3, and shall include all information required by Section 6.5B.

B. If the Parties agree on such Changed Criteria of the proposed Change Order (or modify such Change Order so that the Parties agree on such Changed Criteria), the

Parties shall execute such Change Order, 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) Business Days after Contractor’s receipt of Owner’s proposed Change Order, 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, by issuance of an Owner-directed Change Order in the form attached hereto as Schedule D-2, require Contractor to commence and perform the changed Work specified in the Owner-directed Change Order on a time and materials basis in accordance with Section 6.3. Thereafter, the Parties may discuss the effect of such Owner-directed Change Order on the Changed Criteria (or if the Parties agree on the effect of such Owner-directed 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 have not yet agreed), and if the effects of the Changed Criteria are agreed upon (including the adjustment to the Contract Price, if any), the Parties shall enter into a mutual Change Order in the form of Schedule D-1 superseding the applicable Owner-directed Change Order (previously issued in the form of Schedule D-2). The Parties acknowledge that, with respect to changed Work affecting the Siemens Equipment which can only be performed pursuant to the Siemens Contract, the scope of such changed Work requested by an Owner-directed Change Order may be restricted by the terms set forth in Section 10.2 of the Siemens Contract; provided, however, that Contractor shall use commercially reasonable efforts to have Siemens perform such changed Work notwithstanding the restrictions available to Siemens in Section 10.2 of the Siemens Contract. If the Parties cannot agree on the effect of such Owner-directed Change Order by the date of Final Completion, then the dispute shall be resolved as provided in Article 19. Pending resolution of the dispute, Contractor shall perform the Work as specified in such Owner-directed Change Order in accordance with this Section 6.1C 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 Owner-directed Change Order on all of the Changed Criteria, such agreement shall be recorded by execution by the Parties of a mutually agreed Change Order in the form attached hereto as Schedule D-1, which shall supersede the Owner-directed Change Order previously issued and relating to such changed Work.

6.2 Change Orders Requested by Contractor.

A. Contractor shall have the right to request a Change Order in the event of any of the following occurrences:

1. Changes in Law that materially and adversely affect Contractor’s actual cost (which costs shall be adequately documented and supported by Contractor) of performance of the Work or Contractor’s ability to perform any material requirement under this Agreement, and with respect to any delays (as that term is defined in Section 6.10) caused by such Changes in Law, compensation and a time extension to the Key Milestone Schedule, Guaranteed Substantial

Completion Date and Required Final Completion Date, as applicable, to the extent allowed under Section 6.8;

2. Acts or omissions of Owner that constitute a breach of any express obligation of Owner under this Agreement and materially and adversely affect Contractor’s actual cost (which costs shall be adequately documented and supported by Contractor) of performance of the Work or ability to perform any material requirement under this Agreement and, with respect to delays (as that term is defined Section 6.10) caused by Owner, compensation and a time extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, to the extent allowed under Section 6.8;

3. Force Majeure to the extent allowed under Section 6.7A;

4. Acceleration of the Work ordered by Owner pursuant to Section 5.6;

5. If Contractor discovers at the Site any underground utilities, manmade subsurface obstructions, rocks that require blasting, sinkholes or archeological finds which were (a) not indicated in, or which materially differ from, the Soil Report or the Final Geotechnical Report and (b) otherwise unknown or not identified by or to Contractor, to the extent such discovery has a material and adverse impact on Contractor’s actual cost (which costs shall be adequately documented and supported by Contractor) of performance of the Work or Contractor’s ability to perform any material requirement under this Agreement, and with respect to any delays (as that term is defined in Section 6.10) caused by such discovery, compensation and a time extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, to the extent allowed under Section 6.8;

6. To the extent expressly permitted under Section 2.5B.1 for material differences between the Soils Report and the Final Geotechnical Report;

7. If the ground water constituents and flow rate potential existing at the Site are materially different from the information set forth in Attachment CC, to the extent such difference has a material and adverse impact on Contractor’s actual cost (which costs shall be adequately documented and supported by Contractor) of performance of the Work or Contractor’s ability to perform any material requirement under this Agreement, and with respect to any delays (as that term is defined in Section 6.10) caused by such difference, compensation and a time extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, to the extent allowed under Section 6.8;

8. To the extent expressly permitted under Sections 5.2B, 5.2C, 5.2D, 5.2F, 5.3A, 9.2A, 10.2, 12.9 and 13.2A, Section 1.10.5 of Attachment O, and Attachment AA;

9. Subject to Contractor’s liabilities and responsibilities assumed under Section 3.17, if pre-existing Hazardous Materials are discovered at the Site (other than those discovered during the course of the demolition Work, for which relief is available to the extent provided in Section 5.2D or Attachment AA) that materially and adversely affect Contractor’s actual cost (which costs shall be adequately documented and supported by Contractor) of performance of the Work or Contractor’s ability to perform any material requirement under this Agreement, and with respect to any delays (as that term is defined in Section 6.10) caused by such discovery, compensation and a time extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, to the extent allowed under Section 6.8;

10. An emergency causing imminent and immediate danger to human health or property (excluding the Work), which was not caused by, or did not arise out of, any acts or omission of Contractor or any Subcontractor or Sub-subcontractor or an event of Force Majeure, and which materially and adversely affects Contractor’s actual cost (which costs shall be adequately documented and supported by Contractor) of performance of the Work;

11. Purchase of operating spare parts in accordance with Section 3.4 (including Section 3.4C); or

12. Suspension in Work ordered by Owner pursuant to Section 17.3.

B. Should Contractor desire to request a Change Order under this Section 6.2, Contractor shall, pursuant to Section 6.5, notify Owner in writing and issue to Owner, at Contractor’s expense, a request for a proposed Change Order in the form attached hereto as Schedule D-3, a detailed explanation of the proposed change and Contractor’s reasons for proposing the change, all documentation necessary to verify the effects of the change on the Changed Criteria, and all other information required by Section 6.5. Any adjustments to the Contract Price shall be requested on a lump sum basis.

C. If Owner agrees that a Change Order is necessary and agrees with Contractor’s statement regarding the effect of the proposed Change Order on the Changed Criteria, then Owner shall issue such Change Order, 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 upon execution thereof by the Parties.

D. If the Parties agree that Contractor is entitled to a Change Order but cannot agree on the effect of the proposed Change Order on the Changed Criteria within ten (10) Business Days of Owner’s receipt of Contractor’s written notice and proposed Change Order and all other required information, or if Owner desires that the proposed changed

Work set forth in the proposed Change Order commence immediately the rights, obligations and procedures set forth in Section 6.1C are applicable.

E. If the Parties cannot agree upon whether Contractor is entitled to a Change Order within ten (10) Business Days (or such longer period as may be mutually agreed in writing) of Owner’s receipt of Contractor’s written notice and proposed Change Order, then the dispute shall be resolved as provided in Article 19. Pending resolution of the dispute, Contractor shall continue to perform the Work required under this Agreement, and Owner shall continue to pay Contractor in accordance with the terms of this Agreement and any previously agreed upon or Owner-directed Change Orders. In addition, Contractor shall maintain a detailed accounting of the costs (and any other impacts) incurred by Contractor for Work performed by Contractor for which it has requested a Change Order and which Owner disagrees that a Change Order is entitled pursuant to this Section 6.2E. Such costs and other impacts to the Work shall be reported to Owner within the Monthly Progress Reports.

6.3 Contract Price Adjustment; Contractor Documentation. If a Change Order is executed on a time and materials basis pursuant to Section 6.1C or 6.2D, then the costs incurred in performing such Change Order shall be determined as follows:

A. Direct Craft Labor. Direct craft labor costs shall be based upon actual hours expended by such craft labor for the time and materials Work at the published union wage scales.

B. Small Tool and Supplies. Costs for small tools and supplies shall be determined by ***.

C. Construction Equipment. With respect to construction equipment used to perform the time and materials Work, Contractor shall be paid for incremental costs incurred only (over and above that which is incurred to perform the Work for the Contract Price) at ***.

D. Materials and Subcontracts. Materials purchased by Contractor for the time and materials Work, and time and materials Work performed by Subcontractors and Sub-subcontractors, shall be invoiced to Owner ***.

E. Management, Engineering and Design. Costs for Contractor’s project management, engineering and design services in performing time and materials Work shall be based upon ***.

F. Taxes. If Contractor incurs any California sales and use Taxes in the course of performing the time and materials Work, Owner shall reimburse Contractor for the actual cost of such California sales and use Taxes properly paid by Contractor under Applicable Law.

G. General and Administrative Expenses. Contractor shall be reimbursed for general and administrative expenses and all other overhead, markups and multipliers applicable to the time and materials Work by ***.

H. Profit. Contractor’s profit for the time and materials Work ***.

Unless otherwise agreed in writing by Owner prior to the incurrence of the cost, the foregoing costs and markups shall be the sole costs and markups invoiced to Owner for Change Order Work performed on a time and materials basis. Contractor shall use reasonable efforts to minimize costs incurred on a time and material basis (consistent with the requirements of this Agreement) and shall provide Owner with options for reducing such costs whenever possible. The foregoing costs shall be supported by reasonable documentation, including daily work logs, time sheets, invoices and receipts.

6.4 Change Orders Act as Accord and Satisfaction. Change Orders agreed pursuant to Section 6.1B or 6.2C by the Parties, and Owner-directed Change Orders entered into pursuant to Section 6.1C or 6.2D on a time and materials basis and which the Parties have subsequently agreed upon the effect of such Owner-directed Change Order and executed a superseding and mutually agreed upon Change Order as provided in Section 6.1B or 6.2C shall constitute a full and final settlement and accord and satisfaction of all effects of the change as described in the Change Order upon the Changed Criteria and shall be deemed to compensate Contractor fully for such change. Accordingly, Contractor expressly waives and releases any and all right to make a claim or demand or to take any action or proceeding against Owner for any other consequences arising out of, relating to, or resulting from such change reflected in such Change Order, whether the consequences result directly or indirectly from such change reflected in such Change Order, including any claim or demand for damages due to delay, disruption, hindrance, impact, interference, inefficiencies or extra work arising out of, resulting from, or related to, the change reflected in that Change Order (including any claims or demands that any Change Order or number of Change Orders, individually or in the aggregate, have impacted the unchanged Work).

6.5 Timing Requirements for Notifications and Change Order Requests by Contractor. Should Contractor desire to seek an adjustment to the Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date, the Required Final Completion Date, the Payment Schedule, any of the Minimum Acceptance Criteria or Performance Guarantees or any other modification to any other obligation of Contractor under this Agreement for any circumstance that Contractor has reason to believe may give rise to a right to request the issuance of a Change Order, Contractor shall, with respect to each such circumstance:

A. notify Owner in writing of the existence of such circumstance within twenty (20) Days after the date that Contractor knew or reasonably should have known of the first occurrence or beginning of such circumstance, provided that (i) if such circumstance is an emergency, oral notice shall be given immediately, followed by a written notice within five (5) Business Days after the date such oral notice is provided, (ii) if such circumstance is considered by Contractor to be an event of Force Majeure, written notice shall be provided within four (4) Business Days after the commencement of such occurrence that is considered a Force Majeure and (iii) such notice shall be given as soon as practicable, and prior to the expiration of such twenty (20) Day period, should any action or inaction by Owner or Contractor be required or necessary in relation to such circumstance to prevent or mitigate any damages or losses to either Party. In the notice required under this Section 6.5A notice, Contractor shall state, in as reasonable of detail as is practicable under the circumstances, all known and presumed facts upon which its claim is based, including the

character, duration and extent of such circumstance, the date Contractor first knew of such circumstance, any activities impacted by such circumstance, the cost and time consequences of such circumstance (including showing the impact of such circumstance, if any, on the critical path of the CPM Performance Measurement Baseline Schedule) and any other details or information that are expressly required under this Agreement and any reasonably available information and documents relevant to such claim or circumstance. Contractor shall only be required to comply with the notice requirements of this Section 6.5A once for continuing circumstances, provided the notice expressly states that the circumstance is continuing and includes Contractor’s best estimate of the impact on any Changed Criteria by such circumstance; and

B. submit to Owner a request for a proposed Change Order as soon as reasonably practicable after giving Owner written notice but in no event later than twenty (20) Days after the completion of each such circumstance, together with a written statement (i) detailing why Contractor believes that a Change Order should be issued, plus all documentation reasonably requested by or necessary for Owner to determine the factors necessitating the possibility of a Change Order and all other information and details expressly required under this Agreement (including the information required by Schedule D-4, detailed estimates and cost records, daily time sheets and a graphic demonstration using the CPM Performance Measurement Baseline Schedule, showing Contractor’s entitlement to a time extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, pursuant to the terms of this Agreement, which shall be provided in hard copy and in an electronic format meeting the requirements of Attachment U); and (ii) setting forth the effect, if any, which such proposed Change Order would have for the Work on any of the Changed Criteria. If it is not possible for Contractor to provide all of the information required under this Section 6.5B to be submitted with such proposed Change Order within such twenty (20) Day period, Contractor shall provide Owner with as much information as possible as well as a written explanation of the reason additional time is required. With respect to any information not provided within such twenty (20) Day period, Contractor shall exercise reasonable diligence to provide such information as soon as possible, but in no event later than thirty (30) Days following Contractor’s submission of such proposed Change Order.

The Parties acknowledge that Owner may be prejudiced if Contractor fails to provide the notices and proposed Change Orders as required under this Section 6.5, and agree that such requirements are an express condition precedent necessary to any right for an adjustment in Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date, the Required Final Completion Date, the Payment Schedule, any Work, any of the Minimum Acceptance Criteria or Performance Guarantees or any other modification to any other obligation of Contractor under this Agreement. Accordingly, if Contractor fails to materially comply with the requirements of this Section 6.5 in connection with notices and proposed Change Orders (with the exception of the timing requirements set forth in this Section 6.5, which require strict compliance), any and all claims (including any claim for an adjustment in the Contract Price, Key Milestone Schedule, Guaranteed Substantial Completion Date, Required Final Completion Date or any other modification to any other obligation of Contractor under this Agreement) that should have been provided in such notice or proposed Change Order are waived and released by Contractor to the extent that

Owner is prejudiced as a result of Contractor failing to comply with the requirements of this Section 6.5.

6.6 Adjustment Only Through Change Order. No change in the requirements of this Agreement, whether an addition to, deletion from, suspension of or modification to this Agreement, including any Work, shall be the basis for an adjustment for any change in the Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date, the Required Final Completion Date, Payment Schedule, any Work, any of the Minimum Acceptance Criteria or Performance Guarantees or any other obligations of Contractor or right of Owner under this Agreement unless and until such addition, deletion, suspension or modification has been authorized by a Change Order executed and issued in accordance with and in strict compliance with the requirements of this Article 6. Contractor shall not perform any change in the Work unless and until such change is authorized pursuant to this Article 6, and should Contractor perform or claim to perform any changes in the Work prior to authorization by Change Order, all such costs and expenses incurred by Contractor shall be for Contractor’s account. No course of conduct or dealings between the Parties, nor express or implied acceptance of additions, deletions, suspensions or modifications to this Agreement, including any Work, and no claim that Owner has been unjustly enriched by any such addition, deletion, suspension or modification to this Agreement shall be the basis for any claim for an adjustment in the Contract Price, the Key Milestone Schedule, the Guaranteed Substantial Completion Date, the Required Final Completion Date, the Payment Schedule, any Work, any of the Minimum Acceptance Criteria, Performance Guarantees or any other obligations of Contractor under this Agreement.

6.7 Force Majeure.

A. Contractor Relief. If the commencement, prosecution or completion of the Work is delayed by Force Majeure, then Contractor shall be entitled to an extension to the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date, as applicable, if such delay affects the performance of any Work that is on the critical path of the CPM Performance Measurement Baseline Schedule and Contractor complies with the notice and Change Order request requirements in Section 6.5 and the mitigation requirements in Section 6.11. The Parties agree that Contractor’s sole remedy for such delay shall be an adjustment to the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date, as applicable, pursuant to a Change Order. Any adjustment to the Key Milestone Schedule, the Guaranteed Substantial Completion Date and the Required Final Completion Date, as applicable, shall be recorded in a Change Order.

B. Owner Relief. Subject to Section 6.7C, Owner’s obligations under this Agreement shall be suspended to the extent that performance of such obligations is delayed by Force Majeure.

C. Payment Obligations. No obligation of a Party to pay moneys due and owing under this Agreement shall be excused by reason of Force Majeure.

6.8 Delay Caused by Owner or Changes in Scope of Work. Should Owner or any Person acting on behalf of or under the control of Owner delay the commencement, prosecution or

completion of the Work, and to the extent such delay is not attributable to Contractor or its Subcontractors or Sub-subcontractors but is caused by Owner’s breach of an express obligation of Owner under this Agreement or is caused by Owner’s ordering a change in the Scope of the Work (provided that a Change Order has been issued in accordance with Section 6.1), then Contractor shall be entitled to an adjustment in the Contract Price and an extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, to the extent (a) such delay affects the performance of any Work that is on the critical path of the CPM Performance Measurement Baseline Schedule and (b) Contractor complies with the notice and Change Order request requirements in Section 6.5 and the mitigation requirements of Section 6.11. Any adjustment to the Contract Price shall be for reasonable, additional direct costs incurred by Contractor for such delay meeting the requirements of this Section 6.8, and any adjustments to the Contract Price, Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, shall be recorded in a Change Order. The Parties agree that if they execute a Change Order with respect to any change in the Scope of Work described in this Section 6.8, any delay arising out of such change in the Scope of Work and meeting the requirements of this Section 6.8 shall be included in the Change Order incorporating such change in the Scope of Work.

6.9 Schedule Extension. ***

6.10 Delay. For the purposes of Article 6, the term “delay” shall include hindrances, disruptions or obstructions, or any other similar term in the industry and the resulting impact from such hindrances, disruptions or obstructions, including inefficiency, impact, ripple or lost production. For the avoidance of doubt, the Parties recognize and agree that for the purposes of Article 6, a work activity not on the critical path can become on the critical path, and if a delay causes a work activity off the critical path to become a critical path activity, Contractor is entitled to an extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, for those days of delay after which the non-critical path activity became a critical path activity, provided that such delay satisfies the other requirements under Article 6.

6.11 Contractor Obligation to Mitigate Delay. In no event shall Contractor be entitled to any adjustment to the Key Milestone Schedule, Guaranteed Substantial Completion Date, Required Final Completion Date and the Contract Price for that portion of delay to the extent Contractor could have taken, but failed to take, commercially reasonable actions to mitigate such delay.

ARTICLE 7

CONTRACT PRICE AND PAYMENTS TO CONTRACTOR

7.1 Contract Price. As compensation in full to Contractor for the full and complete performance of the Work and all of Contractor’s other obligations under this Agreement, Owner shall pay and Contractor shall accept Four Hundred Ninety Nine Million Twelve Thousand Eighty One U.S. Dollars (U.S.$499,012,081) (the “Contract Price”). The Contract Price is subject to adjustment only by Change Order as provided in Article 6, and includes all Taxes, costs, charges, and expenses of whatever nature applicable to the Work (other than those California sales and use Taxes for which Owner shall reimburse Contractor pursuant to Article 8). For the avoidance of doubt, the Contract Price includes all costs, markups and other expenses for the Siemens

Equipment (other than the California sales and use Taxes for which Owner shall reimburse Contractor pursuant to Article 8). The Parties agree that (i) amounts paid by Owner to Contractor pursuant to the MOU shall be credited towards the EPC Payment Milestone portion of the Contract Price and (ii) amounts paid by Owner to Siemens prior to assignment of the Siemens Contract to Contractor pursuant to Section 22.8 shall be credited towards the Siemens Equipment Payment Milestone portion of the Contract Price.

7.2 Interim Payments.

A. Payments. Payments shall be made by Owner to Contractor in accordance with the Payment Schedule set forth in Attachment C (as may be amended by Change Order pursuant to Section 6.1B or 6.2C), which allocates (i) Two Hundred Eighty Six Million Eight Hundred Twenty Three Thousand Six Hundred Sixty Five U.S Dollars (U.S.$286,823,665) of the Contract Price to be paid based on completion of the EPC Payment Milestones set forth in Schedule C-1 (the “EPC Payment Milestone portion of the Contract Price”) and (ii) Two Hundred Twelve Million One Hundred Eighty Eight Thousand Four Hundred Sixteen U.S. Dollars (U.S.$212,188,416) of the Contract Price to be paid based on completion of the Siemens Equipment Payment Milestones set forth in Schedule C-2 (“Siemens Equipment Payment Milestone portion of the Contract Price”), provided that Contractor is otherwise in material compliance with the terms of this Agreement. That portion of the Contract Price set forth in the foregoing sentence to be paid based upon Siemens Equipment Payment Milestones corresponds to the payment milestones and progress payments to be made by Contractor to Siemens under the Siemens Contract and contains no further costs, expenses, markups, profit, overhead or other expenditures. Owner shall also make payments to Contractor for any Owner-directed Change Orders issued in accordance with Section 6.1C or 6.2D and shall reimburse applicable California sales and use Taxes in accordance with Article 8. Each payment shall be subject to Retainage and Owner’s right to withhold payments under this Agreement, including Sections 7.5 and 14.3. Payments shall be made in U.S. Dollars to an account designated by Contractor. The Payment Schedule, including the Payment Milestones, shall be amended only by Change Order pursuant to this Agreement.

B. Invoices. Within ten (10) Days after the end of each Month, Contractor shall submit to Owner an Invoice for (i) all EPC Payment Milestones completed during the prior Month, if any, as set forth in Schedule C-1, less the Retainage to be withheld by Owner for such amount, (ii) all Siemens Equipment Payment Milestones completed during the prior Month, if any, as set forth in Schedule C-2 and (iii) California sales and use Taxes incurred in the procurement of the Siemens Equipment in accordance with Article 8. Contractor shall not be entitled to any payment whatsoever for any portion of the Work relating to a particular Payment Milestone until such Payment Milestone is fully completed. Such Monthly Invoice shall also include amounts properly due and owing for Work performed during the prior Month and pursuant to an Owner-directed Change Order issued pursuant to Section 6.1C or 6.2D, less Retainage. All Invoices, other than the Invoice for final payment under this Agreement, shall be in the form of Schedule I-1, and shall include all documentation supporting its request for payment as required under this Agreement. Contractor shall provide documentation such as invoices and receipts supporting all amounts billed for Owner-directed Change Orders issued pursuant to Section 6.1C or 6.2D.

C. Interim Lien and Claim Waivers. Each Invoice received by Owner prior to Final Completion shall be accompanied by (i) a fully executed Interim Waiver and Release of Liens from Contractor in the form of Schedule K-1, and a fully executed Interim Claim Waiver from Contractor in the form of Schedule K-2, for all Work performed through the date for which payment is requested, (ii) fully executed Interim Waiver and Release of Liens from each Major Subcontractor in the form set forth in Schedule K-3, and fully executed Interim Claim Waivers from each Major Subcontractor in the form set forth in Schedule K-4, for all Work performed through the date for which payment is requested and (iii) if requested by Owner, fully executed Interim Waiver and Release of Liens from all Major Sub-subcontractors requested substantially in the form set forth in Schedule K-3 (but nevertheless conforming with Applicable Law), and fully executed Interim Claim Waivers from all Major Sub-subcontractors requested in substantially the form set forth in Schedule K-4, for all Work performed through the date for which payment is requested; provided, however, with respect Siemens, receipt of Interim Waiver and Release of Liens and Interim Claim Waivers from Siemens will be in accordance with the form and content requirements set forth in the Siemens Contract; provided further, however, with respect to Major Sub-subcontractors under Siemens, receipt of Interim Waiver and Release of Liens and Interim Claim Waivers from such Major Sub-subcontractors will be in accordance with the form, content and timing requirements set forth in the Siemens Contract. Interim Waiver and Release of Liens and Interim Claim Waivers, however, shall not be required from Major Subcontractors or Major Sub-subcontractors until they have performed Work, and Major Subcontractors and Major Sub-subcontractors shall be required to submit additional Interim Waiver and Release of Liens and Interim Claim Waivers only if they have performed Work not covered by a previous Interim Waiver and Release of Liens and Interim Claim Waiver. Submission of all Interim Waiver and Release of Liens and Interim Claim Waivers in accordance with this Section 7.2C is a condition precedent to payment of any Invoice.

D. Review and Approval. Each Invoice shall be reviewed by Owner and, upon Owner’s reasonable request, Contractor shall furnish such supporting documentation and certificates and provide such further information as may be reasonably requested by Owner. Unless disputed by Owner, each Invoice (less any withholdings allowed under this Agreement, including Retainage) shall be due and payable thirty (30) Days after it, and all documentation required under this Agreement, is received by Owner. If an Invoice is disputed by Owner, then payment shall be made for all undisputed amounts and the dispute shall be resolved pursuant to Article 19. Payment on disputed amounts shall be made as soon as such dispute is resolved.

E. Maximum Cumulative Payment Amounts. The Parties have agreed upon and set forth in Schedule C-3 a schedule of the maximum cumulative amounts that Contractor is allowed to invoice Owner at any one time during the performance of the Work (the “Maximum Cumulative Payment Schedule”). Schedule C-3 sets forth both (a) the maximum amount that Contractor can invoice at any one time and allocate to the Siemens Equipment Payment Milestone portion of the Contract Price and (b) the maximum amount Contractor can invoice at any one time (before giving effect to Retainage) and allocate to the EPC Payment Milestone portion of the Contract Price. Schedule C-3 shall only be subject to adjustment pursuant to a Change Order.

F. Cooperation in Invoicing Process. Without in anyway altering the rights, obligations and remedies set forth in this Agreement, the Parties acknowledge that they will reasonably cooperate in the timing of the receipt and review of Invoices and coordinate same with invoices received by Contractor under the Siemens Contract with the view to have payment milestones that are properly earned and invoiced under the Siemens Contract included as a Siemens Equipment Payment Milestone in the Invoice under this Agreement in the corresponding Month.

7.3 Final Completion and Final Payment. Upon Final Completion, Contractor shall, in addition to any other requirements in this Agreement for achieving Final Completion, including those requirements set forth in Section 1.1 for the definition of Final Completion, submit a fully executed final Invoice in the form attached hereto as Schedule I-2, along with (i) a statement summarizing and reconciling all previous Invoices, payments and Change Orders, (ii) an affidavit that all payrolls, Taxes, liens, charges, claims, demands, judgments, security interests, bills for Equipment, and any other indebtedness connected with the Work have been paid, (iii) fully executed Final Waiver and Release of Liens and Final Claim Waiver from Contractor in the forms of Schedule K-5 and K-6, respectively, (iv) fully executed Final Waiver and Release of Liens and Final Claim Waivers from each Major Subcontractor in the forms set forth in Schedule K-7 and K-8, respectively and (v) if requested by Owner, fully executed Final Waiver and Release of Liens and Final Claim Waivers from each Major Sub-subcontractor in substantially the form set forth in Schedule K-7 and K-8, respectively (but nevertheless conforming with Applicable Law); provided, however, with respect Siemens, receipt of the Final Waiver and Release of Liens and Final Claim Waiver from Siemens will be in accordance with the form and content requirements set forth in the Siemens Contract; provided further, however, with respect to Major Sub-subcontractors under Siemens, receipt of the Final Waiver and Release of Liens and Final Claim Waivers from such Major Sub-subcontractors will be in accordance with the form and content requirements set forth in the Siemens Contract. No later than thirty (30) Days after receipt by Owner of such final Invoice and all requested documentation and achieving Final Completion, Owner shall, subject to its rights to withhold payment under this Agreement, pay Contractor the balance of the Contract Price, including any remaining Retainage.

7.4 Payments Not Acceptance of Work. No payment made hereunder by Owner shall be considered as approval or acceptance of any Work by Owner or a waiver of any claim or right Owner may have hereunder. All payments shall be subject to correction or adjustment in subsequent payments.

7.5 Payments Withheld. In addition to disputed amounts set forth in an Invoice, Owner may, in addition to any other rights under this Agreement, at law or in equity, withhold payment on an Invoice or a portion thereof in an amount and to such extent as may be reasonably necessary to protect Owner from loss due to:

A. Defective Work not remedied in accordance with this Agreement;

B. liens or other encumbrances on all or a portion of the Site, the Work or the Facility, which are filed by any Subcontractor, any Sub-subcontractor or any other Person acting through or under any of them;

C. any material breach by Contractor of this Agreement;

D. the assessment of any fines or penalties against Owner as a result of Contractor’s failure to comply with Applicable Law or Applicable Codes and Standards;

E. a discovery that a Payment Milestone or other Work associated with a prior payment was not in fact achieved, or that Work associated with a prior Payment Milestone contained Defective Work;

F. amounts paid by Owner to Contractor in a preceding Month incorrectly or for which there was insufficient or inaccurate supporting information;

G. Liquidated Damages which Contractor owes under the terms of this Agreement;

H. failure of Contractor to make payments to Subcontractors as required under their respective Subcontracts;

I. failure of Contractor to comply with its monthly progress reporting obligations and scheduling obligations under this Agreement, including as set forth in Sections 3.19A.4, 5.4 and 5.5; or

J. any other reason for which Owner is entitled to withhold payment under this Agreement.

Owner shall pay Contractor the amount withheld if Contractor (i) pays, satisfies or discharges the applicable claim of Owner against Contractor under or by virtue of this Agreement and provides Owner with reasonable evidence of such payment, satisfaction or discharge, (ii) cures all such breaches and Defaults in the performance of this Agreement, or (iii) provides Owner with a standby letter of credit reasonably satisfactory to Owner in the amount of the withheld payment. Owner’s failure to withhold in the event of any of the circumstances described in this Section shall not be deemed to be a waiver of any of Owner’s rights under this Agreement, including Owner’s right to withhold at any time one of the circumstances in Section 7.5A through 7.5J exists.

7.6 Substitution for Retainage; Release of Retainage.

A. Substitution for Retainage. In Contractor’s sole discretion, Contractor may elect to substitute an irrevocable standby letter of credit, in a form acceptable to Owner in its reasonable discretion, in the amount of *** in lieu of Owner withholding Retainage under this Agreement (which such amount of the substitute letter of credit shall be adjusted as the EPC Payment Milestone portion of the Contract Price is adjusted by Change Order). If Contractor makes such an election, Owner shall release any Retainage previously withheld upon receipt of such letter of credit in a form acceptable to Owner and shall thereafter not collect Retainage under this Agreement. The letter of credit provided pursuant to this Section 7.6A shall be issued by a commercial bank in the United States with a long term rating of at least Investment Grade and shall be issued in a form substantially similar to that in Schedule R-1, and Contractor shall replace any substitute

letter of credit, with a letter of credit that meets the requirements of this Section 7.6A, within three (3) Business Days in the event that such commercial bank’s long term rating falls below Investment Grade. Owner shall have the same rights to collect on this substitute letter of credit, upon Owner’s demand, as is set forth in Section 10.2, in the event Contractor fails to timely provide a replacement letter of credit for (i) a substitute letter of credit that is to expire within thirty (30) Days or (ii) a substitute letter of credit issued by a bank that is no longer Investment Grade. In addition, Owner shall have the right to collect upon the substitute letter of credit, upon Owner’s demand, in any instance under this Agreement where Owner is able to (a) withhold or offset payments otherwise due and owing to Contractor, including under Sections 7.5, 12.5B and 14.3, or (b) collect on the Contractor Letter of Credit pursuant to Section 10.2.

B. Release of Retainage at Substantial Completion. Within thirty (30) Days after Substantial Completion and receipt of an Invoice therefor, Owner shall, subject to its right to withhold under this Agreement, release to Contractor all Retainage withheld under this Agreement except for that portion of the Retainage that is equal to ***. In the event Contractor has elected, pursuant to Section 7.6A, to issue a substitute letter of credit in lieu of having Retainage withheld, such substitute letter of credit shall be reduced in value to ***.

7.7 Interest on Late Payments. Any amounts due but not paid hereunder shall bear interest at the lesser of (i) an annual rate equal to ***, or (ii) the maximum rate permitted under Applicable Law.

7.8 Payments During Default. Owner shall not be obligated to make any payments hereunder or payments withheld, at any time in which a Contractor Default shall have occurred and is continuing.

7.9 Offset. Owner may, upon prior written notice to Contractor, offset any amount due and payable from Contractor to Owner against any amount due and payable to Contractor hereunder.

7.10 Currency. Unless otherwise specified, all amounts contained herein are in and shall be paid in U.S. Dollars.

ARTICLE 8

TAXES

8.1 Taxes Generally. The Contract Price includes all Taxes which arise out of or are related to the performance of the Work and Contractor shall be responsible for timely paying all such Taxes; provided, however, Owner shall reimburse Contractor for California sales and use Taxes incurred in the procurement of any Siemens Equipment as well as any interest or penalties which may be imposed by a Governmental Instrumentality at any time on Contractor due to Owner’s failure to timely reimburse Contractor for California sales and use Taxes incurred in the procurement of any Siemens Equipment. Owner’s obligation shall survive termination or completion of the Agreement and shall end only upon the completion of any time period allowed for audit or investigation by applicable Governmental Instrumentalities. To the extent Owner

timely reimburses Contractor for all such California sales and use Taxes for Siemens Equipment, (1) Contractor shall release Owner of any further obligations for payment of such California sales and use Taxes and (2) Contractor shall be responsible for the payment of any interest or penalties related to Contractor’s failure to timely pay such California sales and use Taxes. Owner and Contractor will provide documents, information and data, make submission to Governmental Instrumentalities, and otherwise cooperate as reasonably necessary to minimize the amount of California sales and use Taxes payable for the Siemens Equipment. In the event that Contractor is audited for California sales and use Taxes for the Siemens Equipment, Contractor shall timely inform Owner of such audit, allow Owner to assist with audit strategy and, at Owner’s expense, allow Owner to take responsibility for defending the audit, protest or appeal based on mutually satisfactory arrangements. Contractor shall reasonably cooperate with Owner to assist in attempting to allocate local and district California sales and use Taxes to the Site (which may include Contractor applying for a jobsite sub-permit), including reasonable assistance in causing local California sales and use Taxes to be assigned to the Site rather than to Contractor’s (or any Subcontractor’s) regular place of business in California. Contractor will reasonably cooperate with any joint refund claim that Owner, or its agents, wishes to file for potentially overpaid California sales and use Taxes up to a period of three (3) years after Substantial Completion or until the running of the applicable statute of limitations, whichever is longer.

8.2 California Revenue Taxes. Notwithstanding Section 8.1, if a Change in Law occurs relating to the method in or the rate at which revenue received by Contractor through payments made by Owner under this Agreement is taxed by the State of California or other local California taxing jurisdiction (collectively, “California Revenue Taxes”), Contractor or Owner, as applicable, shall be entitled to a Change Order to adjust the Contract Price (upwards or downwards, as applicable) solely to reflect the net impact of the imposition of the California Revenue Taxes, accounting for any reduction in the Contractor’s Taxes attributable to changes in Applicable Law occurring after the Effective Date that have reduced Contractor’s Taxes in the State of California arising out of the performance of the Work (excluding those Taxes reimbursed by Owner pursuant to Section 8.1). Notwithstanding Section 3.13B, Owner shall have all audit rights necessary to develop or review a proposed Change Order related to this Section 8.2. In addition, either Party may, at its sole expense, employ an independent accounting firm to review the changes to Contractor’s Tax liability in the context of this Section 8.2 and opine as to the amount of any Contract Price adjustment available under this Section 8.2; provided that such opinion shall not be binding upon either Party. In the event the Parties cannot agree upon the adjustment to the Contract Price due under this Section 8.2, such Dispute shall be resolved in accordance with Article 19.

ARTICLE 9

TITLE AND RISK OF LOSS

9.1 Title.

A. Clear Title. Contractor warrants and guarantees that legal title to and ownership of the Work and the Facility shall be free and clear of any and all liens, claims, security interests or other encumbrances when title thereto passes to Owner.

B. Title to Work. Title to all or any portion of the Work (other than Work Product) shall pass to Owner upon the earlier of (i) payment by Owner therefor, (ii) incorporation of such Work into the Facility or (iii) storage at the Site. Transfer of title to Work shall be without prejudice to Owner’s right to reject Defective Work, or any other right in the Agreement.

9.2 Risk of Loss.

A. Prior to Substantial Completion. Notwithstanding passage of title as provided in Section 9.1 of this Agreement, Contractor shall bear the risk of physical loss and physical damage with respect to the Facility and the Equipment until Substantial Completion.

1. If Owner’s builder’s risk or marine cargo insurance makes a payout for an event of physical loss or physical damage to the Facility or the Equipment, then Contractor’s liability for the builder’s risk deductible and marine cargo deductible covering such event of physical loss or physical damage shall be limited to Five Hundred Thousand U.S. Dollars (U.S.$500,000) per occurrence and One Million U.S. Dollars (U.S.$1,000,000) annual aggregate on a no fault basis; provided that, during hot testing, Contractor’s liability for the builder’s risk deductible covering such event of physical loss or physical damage shall be limited to One Million U.S. Dollars (U.S.$1,000,000) per occurrence and One Million U.S. Dollars (U.S.$1,000,000) annual aggregate on a no fault basis. Notwithstanding the foregoing limitations on Contractor’s liability for deductibles on Owner’s builder’s risk and marine cargo insurance, Contractor’s liability for the deductible of Owner’s builder’s risk insurance covering such event of physical loss or physical damage shall be greater than such foregoing limitations to the extent that Siemens, under the Siemens Contract, pays amounts greater than such foregoing amounts for the same occurrence. Contractor shall use best efforts to enforce the Siemens Contract obligations to their fullest extent and shall, upon Owner’s written request, assign the claim for such greater amounts to Owner so that Owner can enforce the terms of the Siemens Contract. This Section 9.2A.1 is only intended to limit Contractor’s liability for the deductible under Owner’s builder’s risk and marine cargo insurance policies, and except for this limitation, Contractor shall bear the risk of loss and damage as specified in Section 9.2A.

2. If and to the extent Owner’s builder’s risk insurance or marine cargo insurance makes a payout for an event of physical loss or physical damage to the Facility or the Equipment, then with respect to the repair, reconstruction or replacement of such physical loss or physical damage, Contractor shall be entitled to a Change Order adjusting the Contract Price for: (i) the cost to repair, reconstruct or replace the damaged Work covered by the builder’s risk insurance or marine cargo insurance proceeds; (ii) the cost of debris removal covered by the builder’s risk insurance or marine cargo insurance proceeds, and (iii) to the extent recovered by Owner under insurance provided by Owner under Section 2.1 of Attachment O, the cost to accelerate or expedite such repair, reconstruction or replacement and stand-by costs.

B. After Substantial Completion. After Substantial Completion, Owner shall bear the risk of physical loss and physical damage to the Facility; provided that, notwithstanding the foregoing, (i) under no circumstances shall this Section 9.2B be interpreted to relieve Contractor of its other obligations or liabilities under this Agreement, including its obligations with respect to Defective Work and Corrective Work; provided further that, notwithstanding the transfer of risk of physical loss or physical damage of the Facility to Owner pursuant to this Section 9.2B, to the extent portions of the Facility are damaged or affected (a) by any Defect after achievement of Substantial Completion but before expiration of the Defect Correction Period or (b) due to the fault or negligence of Contractor or any of its Subcontractors or Sub-subcontractors, Contractor shall be liable to correct, and, if Owner performs any or all of the correction, liable for Owner’s costs and expenses to correct, such damaged or affected portion of the Facility, whether by repair, replacement or otherwise, except that such liability shall be limited to Five Hundred Thousand U.S. Dollars (U.S.$500,000) per occurrence and One Million U.S. Dollars (U.S.$1,000,000) in the aggregate. Notwithstanding the foregoing limitations on Contractor’s liability, Contractor shall also pay Owner more than the foregoing limits to the extent that Siemens, under the Siemens Contract, pays amounts greater than such foregoing amounts for the same occurrence, and Contractor shall use best efforts to enforce the Siemens Contract obligations to their fullest extent and shall, upon Owner’s written request, assign the claim for such greater amounts to Owner so that Owner can enforce the terms of the Siemens Contract. For the purposes of clarity, the limitation of Contractor’s liability in this Section 9.2B, with respect to portions of the Facility damaged or affected by a Defect, shall not apply to liabilities incurred with respect to the repair, replacement or correction of the Defect itself (as Contractor’s obligations to correct the Defect, at its sole cost and expense, are set forth in clause (i) of Section 13.3), but shall only apply to liabilities incurred for the correction of that portion of the Facility damaged or affected by such Defect. Owner shall cause its insurers to issue a waiver of subrogation in favor of Contractor and its Subcontractors and Sub-subcontractors which is consistent with Contractor’s limitations of liability set forth in this Section 9.2B.

ARTICLE 10

INSURANCE AND PERFORMANCE SECURITY

10.1 Insurance.

A. Provision of Insurance. The Parties shall provide the insurance as specified in Attachment O on terms and conditions stated therein.

B. Failure to Provide Required Insurance. IN THE EVENT THAT LIABILITY FOR ANY LOSS OR DAMAGE IS DENIED BY THE UNDERWRITER OR UNDERWRITERS IN WHOLE OR IN PART DUE TO THE VITIATION OF SAID INSURANCE RESULTING FROM AN ACT OR OMISSION BY CONTRACTOR, OR FOR ANY OTHER REASON ATTRIBUTABLE TO CONTRACTOR, OR IF CONTRACTOR FAILS TO MAINTAIN ANY OF THE INSURANCE HEREIN REQUIRED, THEN CONTRACTOR SHALL DEFEND, INDEMNIFY AND HOLD THE OWNER GROUP HARMLESS AGAINST ALL LOSSES WHICH WOULD OTHERWISE HAVE BEEN COVERED BY SAID INSURANCE.

10.2 Contractor Letter of Credit. Within ten (10) Days after delivery of the GTG LNTP, Contractor shall deliver to Owner an irrevocable standby letter of credit in the amount of Thirty One Million Eight Hundred Thousand U.S. Dollars (U.S.$31,800,000), and in a form substantially similar (i.e., immaterial changes in form necessitated by the issuing bank) to Schedule R-1, issued by a commercial bank in the United States of America with a long-term rating of at least Investment Grade (“Contractor Letter of Credit”). The amount of the Contractor Letter of Credit shall decrease to an aggregate amount of Ten Million Six Hundred Thousand U.S. Dollars (U.S.$10,600,000) upon the commercial bank’s receipt from Owner of (i) a copy of the Substantial Completion Certificate signed by Contractor, (ii) a copy of the Substantial Completion Certificate signed by Owner showing that Owner accepts the Substantial Completion Certificate and (iii) a statement by the Owner verifying that (a) Contractor has paid all Substantial Completion Delay Liquidated Damages due and owing under the Agreement and (b) Contractor has delivered to Owner a fully executed Interim Waiver and Release of Liens and a fully executed Interim Claim Waiver from Contractor in the form of Schedules K-1 and K-2, respectively, fully executed Interim Waiver and Release of Liens and Interim Claim Waivers from all Major Subcontractors in the form of Schedules K-3 and K-4, respectively and, if requested by Owner, fully executed Interim Waiver and Release of Liens and Interim Claim Waivers from all Major Sub-subcontractors substantially in the form of Schedule K-3 and K-4, respectively, covering all Work at least up to the date of Substantial Completion. No later than fourteen (14) Days after Owner’s acceptance of the Substantial Completion Certificate, and if Contractor has (1) paid all Substantial Completion Delay Liquidated Damages due and owing under the Agreement (2) provided the Interim Waivers and Release of Liens and Interim Claim Waivers as set forth in the foregoing sentence, Owner shall provide the commercial bank that issued the Contractor Letter of Credit with written notice of such acceptance. The Contractor Letter of Credit shall remain in full force and effect from the issuance of the Contractor Letter of Credit through the expiration of the Defect Correction Period for all Work, at which time the Contractor Letter of Credit will be returned to Contractor if Contractor is otherwise in compliance with its obligations under Article 13. No later than fourteen (14) Days following the expiration of the Defect Correction Period and if Contractor is otherwise in compliance with its obligations under Article 13, Owner shall provide the commercial bank that issued the Contractor Letter of Credit with written notice of the expiration of the Defect Correction Period. As used herein, “Investment Grade” means a rating of at least A by Standard & Poor’s and at least A2 by Moody’s Investors Service. If at any time the rating of the commercial bank that issued the Contractor Letter of Credit falls below either of such ratings, Contractor shall replace the Contractor Letter of Credit within ten (10) Business Days with an equivalent instrument issued by a commercial bank in the United States of America meeting such rating requirements. Owner shall have the right to draw down on or collect against such Contractor Letter of Credit in the event of (i) a Default by Contractor which has not been cured within the applicable cure period as set out in Section 17.1B, (ii) Liquidated Damages owed by Contractor to Owner under the Agreement or (iii) any amounts owed to Owner arising out of or relating to a breach of any of Contractor’s obligations under Article 13; provided that Owner first requests, in writing, such payment from Contractor and provides Contractor with at least five (5) Days prior written notice of Owner’s intent to draw upon the Contractor Letter of Credit. The amount drawn on the Contractor Letter of Credit shall not be greater than the amount that Owner, at the time of the drawing, reasonably estimates is owed it under the Agreement for Liquidated Damages, liabilities, damages, losses, costs or expenses or is necessary to remedy the Default or breach of the Agreement. In addition to the foregoing draw rights, (i) should the commercial bank notify Owner and Contractor pursuant to the terms of the Contractor Letter of Credit that it has decided not to extend the Contractor Letter of Credit beyond the then current expiration date, Owner shall also have the right to draw down on or collect against the Contractor Letter of Credit for all remaining funds in the Contractor Letter of Credit upon Owner’s demand if Contractor has not, prior to thirty (30) Days before the then current expiration date, delivered to Owner a replacement letter of credit substantially identical to the Contractor Letter of Credit and from a commercial bank meeting the requirements in this Section 10.2, and (ii) Owner shall also have the right to draw down on or collect against the Contractor Letter of Credit for all remaining funds available under such Contractor Letter of Credit upon Owner’s demand if the issuing bank is no longer Investment Grade and Contractor has not, within the applicable time period set forth in this Section 10.2, delivered to Owner a replacement letter of credit substantially identical to the Contractor Letter of Credit from a commercial bank meeting the requirements set forth in this Section 10.2; provided, however, in the event of a draw down on or collection against the Contractor Letter of Credit by Owner pursuant to this sentence, if Contractor subsequently provides Owner with a replacement letter of credit meeting the requirements of this Section 10.2 (and no other contractual right to draw upon the Contractor Letter of Credit exists at the time), Owner shall immediately return the drawn funds to Contractor. In the event the Contract Price is increased by one or more Change Orders in accordance with the terms of this Agreement, by a cumulative amount of Five Million U.S. Dollars (U.S.$5,000,000) or more, Contractor shall, at Owner’s request, increase the amount of the Contractor Letter of Credit to reflect the proportionate increase in such Contract Price. Such increase in value of the Contractor Letter of Credit shall be reflected in a Change Order mutually agreed upon by the Parties, and shall reflect the reasonable cost for the increase to the Contractor Letter of Credit. Partial drawings are permitted under the Contractor Letter of Credit. Contractor shall not be entitled to any payment under this Agreement, otherwise due and owing to Contractor by Owner after issuance of the GTG LNTP, until Contractor has issued the Contractor Letter of Credit to Owner.

10.3 Contractor’s Parent Guarantee. Within five (5) Days after the Effective Date, Contractor shall provide to Owner an irrevocable, unconditional corporate guarantee from Kiewit Construction Company, in the form of Schedule Z-1, in favor of Owner and guaranteeing all of Contractor’s obligations and liabilities under this Agreement for the full duration of Contractor’s obligation and liabilities under this Agreement. Contractor shall not be entitled to any compensation under the Agreement unless and until Contractor provided the foregoing corporate guarantee to Owner in accordance with this Section 10.3.

10.4 Owner’s Letter of Credit. Within ten (10) Days after the later of (i) Contractor’s receipt from Siemens of the Siemens letter of credit to be provided under the Siemens Contract and (ii) Owner’s receipt of the Contractor Letter of Credit from Contractor to be provided pursuant to Section 10.2, Owner will provide an irrevocable standby letter of credit to Contractor, in a form substantially similar (i.e., immaterial changes in form necessitated by the issuing bank) to Schedule R-2, issued by a commercial bank in the United States of America with a long-term rating of at least Investment Grade (the “Owner Letter of Credit”). The amount of the Owner Letter of Credit shall at all times be no less than the then-current value of the “Termination Payment” (as such term is defined and calculated pursuant to the Siemens Contract) (hereinafter for the purposes of this Agreement referred to as the “Siemens Termination Payment”). When Owner modifies the Owner Letter of Credit in order to maintain an amount that is no less than the then-current value of the Siemens Termination Payment, Contractor shall release the current Owner Letter of Credit within its possession to Owner concurrently with Owner’s delivery of the new Owner Letter of Credit to Contractor. In addition, once the value of the Siemens Termination Payment reaches Zero U.S. Dollars (U.S.$0), Contractor shall promptly return the Owner Letter of Credit to Owner. Contractor’s sole right to draw upon or collect on the Owner Letter of Credit shall be in the event that Owner elects not to take assignment of the Siemens Contract and the Siemens Contract is therefore terminated by Contractor as a result of either (i) a termination for convenience of this Agreement by Owner or (2) a termination of this Agreement by Contractor pursuant to Section 17.5; provided, however, that Contractor (after termination of the Siemens Contract) first requests, in writing, such payment from Owner and provides Owner with at least five (5) Days prior written notice of Contractor’s intent to draw upon the Owner Letter of Credit. In the event that Contractor is entitled to draw upon the Owner Letter of Credit pursuant to this Section 10.4, the amount drawn on the Owner Letter of Credit shall not be greater than the Siemens Termination Payment. If at any time the rating of the commercial bank that issued the Owner Letter of Credit falls below Investment Grade, Owner shall replace the Owner Letter of Credit within ten (10) Business Days with an equivalent instrument issued by a commercial bank in the United States of America that is Investment Grade. In addition to the foregoing draw rights, (i) should the commercial bank notify Owner and Contractor pursuant to the terms of the Owner Letter of Credit that it has decided not to extend the Owner Letter of Credit beyond the then current expiration date, Contractor shall also have the right to draw down on or collect against the Owner Letter of Credit for all remaining funds in the Owner Letter of Credit upon Contractor’s demand if Owner has not, prior to thirty (30) Days before the then current expiration date, delivered to Contractor a replacement letter of credit substantially identical to the Owner Letter of Credit and from a commercial bank meeting the requirements in this Section 10.4, and (ii) Contractor shall also have the right to draw down on or collect against the Owner Letter of Credit for all remaining funds available under such Owner Letter of Credit upon Contractor’s demand if the issuing bank is no longer Investment Grade and Owner has not, within the applicable time period set forth in this Section 10.4, delivered to Contractor a replacement letter of credit substantially identical to the Owner Letter of Credit from a commercial bank meeting the requirements set forth in this Section 10.4; provided, however, in the event of a draw down on or collection against the Owner Letter of Credit by Contractor pursuant to this sentence, if Owner subsequently provides Contractor with a replacement letter of credit meeting the requirements of this Section 10.4 (and no other contractual right to draw upon the Owner Letter of Credit exists at the time), Contractor shall immediately return the drawn funds to Owner. Partial drawings are permitted under the Owner Letter of Credit.

10.5 Owner’s Parent Guarantee. Upon issuance of the GTG LNTP, Owner shall provide Contractor with an irrevocable, unconditional corporate guarantee from Mirant Corporation, in the form of Schedule Z-2, in favor of Contractor, in an amount not to exceed Forty Three Million U.S. Dollars (U.S.$43,000,000), guaranteeing Owner’s payment of the Kiewit Termination Charge in the event of (i) a termination for convenience of this Agreement by Owner or (2) a termination of this Agreement by Contractor pursuant to Section 17.5.

ARTICLE 11

OWNERSHIP OF DOCUMENTATION

11.1 Ownership of Work Product. Owner and Contractor acknowledge that during the course of, and as a result of, the performance of the Work and prior work related to the Facility done by Contractor for Owner (including any work done by Contractor or any of its Affiliates under the MOU), Contractor or its Affiliates, Subcontractors or Sub-subcontractors will create or have created for the Facility certain written materials, plans, Drawings, Specifications, calculations, Books and Records, computer files, or other tangible manifestations of Contractor’s and its Subcontractors’ and Sub-subcontractors’ efforts related to the Work (whether hard copies or electronic copies, but excluding Computer Programs) (hereinafter individually or collectively referred to as “Work Product”). Owner shall own the hard and electronic copies of any Work Product delivered or required to be delivered by Contractor to Owner under the Agreement irrespective of any copyright notices or confidentiality legends which may have been placed in or on such Work Product. Notwithstanding the foregoing, as between Owner and Contractor, Contractor shall retain ownership of all proprietary intellectual property rights owned, created, developed or delivered by Contractor during the performance of the Work or otherwise (including any such proprietary intellectual property embedded in the Work Product) (hereinafter referred to as “Contractor’s Intellectual Property”), and nothing in this Section 11.1 shall result in a transfer of ownership of any Contractor’s Intellectual Property or the proprietary intellectual property owned and developed by Contractor’s Subcontractors or Sub-subcontractors (“Third Party Proprietary Work Product”). With respect to such Contractor’s Intellectual Property and Third Party Proprietary Work Product relating to the Work or the Facility, Contractor hereby grants Owner an irrevocable, perpetual, non-exclusive and royalty-free license (including with the right to assign its rights in accordance with Owner’s assignment rights set forth in Section 22.7) to use, modify and copy such Contractor’s Intellectual Property and Third Party Proprietary Work Product solely for purposes of operating, maintaining, completing, repairing or modifying any part of the Facility and any interfaces between the Facility and the Mirant Delta Facility. All Subcontracts and Sub-subcontractors shall contain provisions consistent with this Section 11.1.

11.2 Computer Programs.

A. Contractor grants to Owner an irrevocable, non-exclusive, and royalty-free license (including with right to assign its rights in accordance with Owner’s assignment rights set forth in Section 22.7) to use Computer Programs for operating, maintaining, completing or repairing the Work; provided, however, that any modification of the Computer Program is either (a) required by Applicable Law, (b) necessary to resolve a Defect or ensure proper operation and maintenance of the Facility or (c) recommended by Siemens. The foregoing license rights granted to Owner shall be no greater than the license rights in such Computer Programs available to Siemens, but shall at all times be sufficient for Owner to operate, maintain and repair the Facility. The term of such license shall extend until the decommissioning or abandonment of the Facility by Owner, its Affiliate or current owner.

B. The license described in this Section 11.2 does not grant any right to the background technology from which the Computer Program was generated or to the source code underlying the Computer Program. Owner is not granted any right to create

derivative works or modify the Computer Programs or merge it with other Computer Programs (except to the extent reasonably necessary to operate, maintain or repair the Facility).

11.3 Owner Provided Documents. All written materials, plans, drafts, specifications, computer files or other documents (if any) prepared or furnished by Owner, its Affiliates or any of Owner’s other consultants or contractors shall at all times remain the property of Owner, and Contractor shall not make use of any such documents or other media for any other project or for any other purpose than as set forth herein. All such documents and other media, including all copies thereof, shall, at Contractor’s option, either be returned to Owner or destroyed upon the earlier of the end of the Defect Correction Period and termination of this Agreement.

ARTICLE 12

COMPLETION AND PERFORMANCE LIQUIDATED DAMAGES

12.1 Notice and Requirements for Pre-Commissioning and Mechanical Completion.

A. Notice of Intent to Commence Pre-Commissioning. Contractor shall give Owner not less than sixty (60) Days’ prior written notice of its intention to commence any pre-commissioning activities required for Mechanical Completion, and, on the tenth (10^th) Day immediately prior to Contractor’s commencing such pre-commissioning activities, Contractor shall provide a second written notice to Owner. Contractor shall comply with all pre-commissioning activities required for Mechanical Completion set forth in this Agreement, including those requirements set forth in the definition of the term Mechanical Completion and those set forth in Attachments A and V.

B. Requirements of Mechanical Completion. No later than three hundred sixty (360) Days after the issuance of the NTP, Contractor shall provide to Owner for its review and comment detailed Mechanical Completion requirements, in the form of checklists, for each applicable system or subsystem of the Facility. Once Contractor has incorporated all of Owner’s comments to the Mechanical Completion checklists (to the extent such comments are consistent with the concepts embodied by Mechanical Completion), such Mechanical Completion checklists shall form a part of the requirements for achieving Mechanical Completion for each system or subsystem of the Facility, as applicable. Contractor shall comply with all requirements for Mechanical Completion set forth in this Agreement, including those requirements set forth in the definition of the term Mechanical Completion, Attachment A and Attachment V and the Mechanical Completion checklists agreed by Owner and Contractor pursuant to this Section. At such time as each system or subsystem of the Facility, as applicable, has achieved Mechanical Completion, Contractor shall certify to Owner in the form of Attachment L for Mechanical Completion of such system or subsystem (“Mechanical Completion Certificate”) that all requirements under this Agreement for Mechanical Completion of such system or subsystem, as applicable, have occurred, including all of the requirements specified in the applicable Mechanical Completion checklist have been completed. The Mechanical Completion Certificate shall be accompanied by all other supporting documentation as may be required to establish that the requirements for Mechanical Completion have been met.

12.2 Notice and Requirements for Substantial Completion. Contractor shall comply with all requirements for Substantial Completion herein, including as set forth in the definition of the term Substantial Completion herein and in Attachment A, Attachment S and Attachment T. Contractor shall give Owner not less than ninety (90) Days’ prior written notice of its intention to commence the initial Performance Tests. Final test procedures shall be determined in accordance with Attachment S for the conduct of the Performance Tests, including the application of corrective curves as set forth in Attachment S. Contractor shall provide labor, equipment, supplies, and all other items necessary for the conduct of the Performance Tests; provided, however, that Owner shall provide operating personnel and natural gas fuel and power in accordance with Sections 4.4 and 4.7. Upon achieving all requirements under this Agreement for Substantial Completion, Contractor shall certify to Owner in the form of Attachment M (“Substantial Completion Certificate”) that all of the requirements under this Agreement for Substantial Completion have occurred. The Substantial Completion Certificate shall be accompanied by all supporting documentation required to establish that the requirements for Substantial Completion have been met.

12.3 Owner Acceptance of Mechanical Completion and Substantial Completion. Owner shall notify Contractor whether it accepts or rejects a Mechanical Completion Certificate or the Substantial Completion Certificate, as the case may be, within ten (10) Business Days following Owner’s receipt thereof. All Work shall continue during pendency of Owner’s review. Acceptance of such Mechanical Completion or Substantial Completion Certificate shall be evidenced by Owner’s signature on such Mechanical Completion or Substantial Completion Certificate, which shall be forwarded to Contractor with such notice. If Owner does not agree that Mechanical Completion or Substantial Completion, as the case may be, has occurred, then Owner shall state the basis for its rejection in reasonable detail in a written notice provided to Contractor. The Parties shall thereupon promptly and in good faith confer and make all reasonable efforts to resolve such issue. In the event such issue is not resolved within ten (10) Business Days after the delivery by Owner of its notice, Owner and Contractor shall resolve the Dispute in accordance with the dispute resolution procedures provided for under Article 19 herein. Owner’s acceptance shall not relieve Contractor of any of its obligations to perform the Work in accordance with the requirements of this Agreement.

12.4 Minimum Acceptance Criteria as a Condition of Substantial Completion. As a condition of achieving Substantial Completion, each and every Unit shall achieve all Minimum Acceptance Criteria as described in greater detail in this Section 12.4. The Performance Tests for determining whether a Unit achieves the Minimum Acceptance Criteria are described in Attachment S and Attachment T.

A. Minimum Acceptance Criteria Not Achieved. In the event that any Unit fails to achieve any of the Minimum Acceptance Criteria, as evidenced by the Performance Test results, then (i) Substantial Completion shall not occur and (ii) the provisions of Section 14.1 shall apply after the Guaranteed Substantial Completion Date passes without achievement of Substantial Completion. In addition to the foregoing, Contractor shall attempt for a period of one hundred eighty (180) Days (commencing on the date on which the Unit was shown, through the Performance Tests, to have failed to achieve one or more of the Minimum Acceptance Criteria) (“Minimum Acceptance Criteria Correction Period”) to correct the Work to enable the Unit to achieve all of the Minimum Acceptance

Criteria. If the Unit has not achieved all of the Minimum Acceptance Criteria upon the termination of the Minimum Acceptance Criteria Correction Period, then Owner may, in its sole discretion, either (i) grant Contractor an additional Minimum Acceptance Criteria Correction Period under the same terms and conditions as the first, including the application of Section 14.1, or (ii) terminate Contractor for Default, in which case Owner shall be entitled to any and all damages, losses, costs and expenses to the extent permitted under Section 17.1. If, on the other hand, the Unit has achieved all of the Minimum Acceptance Criteria during the Minimum Acceptance Criteria Correction Period (or during the second period, should Owner elect that option), then Contractor shall remain liable to Owner for Substantial Completion Delay Liquidated Damages pursuant to the Agreement and any other damages, costs or expenses for which Contractor is responsible hereunder.

B. Access During Minimum Acceptance Criteria Correction Period. During any Minimum Acceptance Criteria Correction Period, Owner shall provide Contractor with access to the Work sufficient to perform its curative Work under this Agreement, subject to any reasonable security or safety requirements of Owner; provided, however, Owner shall be under no obligation to provide any access to Contractor that would interfere with the operation of the Mirant Delta Facility; provided further, however, if the Guaranteed Substantial Completion Date has passed and thereafter if Owner denies Contractor access to the Unit (or Units) that have failed to meet the Minimum Acceptance Criteria to the extent necessary for Contractor to perform its curative Work, then Contractor shall not be liable for Substantial Completion Delay Liquidated Damages for each Day that Owner so denies Contractor such access for performance of curative Work. Contractor shall provide at least one (1) week’s prior written notice to Owner if performance of the curative Work could interfere with the operation of the Mirant Delta Facility, in which case Owner may place reasonable limitations on Contractor’s access to the Facility such that performance of the Work will cause no disruption to the operation of the Mirant Delta Facility.

C. Delivery of Critical Spare Parts. Notwithstanding the timing of the delivery of operating spare parts under Section 3.4, Contractor shall deliver all Critical Spare Parts no later than the date upon which Contractor achieves Substantial Completion; provided, however, delivery of such Critical Spare Parts shall not be a condition of achievement of Substantial Completion by Contractor. Nevertheless, if Contractor fails to deliver any such Critical Spare Part by Substantial Completion, and thereafter such Critical Spare Part is necessary in order for the Facility to be fully available for commercial operation (as required by CAISO and/or NERC standards), then Contractor shall be liable to Owner for Substantial Completion Delay Liquidated Damages for each Day the Facility is not fully available as a result of such failure to provide such Critical Spare Part until such Critical Spare Part is delivered to the Facility. Such Substantial Completion Delay Liquidated Damages will be assessed in the same manner as if Contractor failed to achieve Substantial Completion by the Guaranteed Substantial Completion Date in accordance with Section 14.1, with the amount of the Substantial Completion Delay Liquidated Damages to be assessed against Contractor (on a per Day basis) being dependent upon the month(s) in which the Facility is not fully available for commercial operation due to the lack of such Critical Spare Part. For purposes of clarity, and by way of example and explanation only, if Contractor failed to timely provide a Critical Spare Part and the

Facility was not fully available for commercial operation during the month of June due to the lack of such Critical Spare Part, then Contractor would be assessed Substantial Completion Delay Liquidated Damages in accordance with the amounts set forth in Section 14.1D.

12.5 Punchlist.

A. Punchlist for Mechanical Completion. Prior to Mechanical Completion for each system or subsystem of the Facility, as applicable, Owner and Contractor shall inspect such Work, and Contractor shall prepare a proposed Punchlist of items identified as needing to be completed or corrected as a result of such inspection. Contractor shall promptly provide the proposed Punchlist to Owner for its review, together with an estimate of the time necessary to complete or correct each Punchlist item. Contractor shall add to the proposed Punchlist any Punchlist items that are identified by Owner during its review, and Contractor shall immediately initiate measures to complete or correct, as appropriate, any item on Contractor’s proposed Punchlist that Owner, in the exercise of its reasonable judgment, believes must be completed or corrected so that such Work will achieve Mechanical Completion. Upon Contractor’s completion or correction of any items necessary to achieve Mechanical Completion, such Punchlist shall govern Contractor’s performance of the Punchlist items for such system or subsystem of the Facility, as applicable, up to Substantial Completion.

B. Punchlist for Substantial Completion. After Mechanical Completion of the Facility and prior to Substantial Completion, Owner and Contractor shall inspect the entire Work, and Contractor shall prepare an updated and revised proposed Punchlist of items identified as needing to be completed or corrected as a result of such inspection. Contractor shall promptly provide the proposed, updated and revised Punchlist to Owner for its review and written approval, together with an estimate of the time and cost necessary to complete or correct each Punchlist item. Contractor shall add to the proposed, updated and revised Punchlist any Punchlist items that are identified by Owner during its review, and Contractor shall immediately initiate measures to complete or correct, as appropriate, any item on Contractor’s proposed, updated and revised Punchlist or otherwise that Owner in the exercise of its reasonable judgment, believes must be completed or corrected to achieve Substantial Completion. Upon Contractor’s completion or correction of any items necessary to achieve Substantial Completion and Owner’s written approval of Contractor’s proposed Punchlist (such approval not to be unreasonably withheld), such Punchlist shall govern Contractor’s performance of the Punchlist items up to Final Completion. All Work on the Punchlist shall be completed within ninety (90) Days after achievement of Substantial Completion, or Owner may, in addition to any other rights that it may have under this Agreement, at law or in equity, complete such Punchlist Work at the expense of Contractor. In the event Owner elects to complete such Punchlist Work, Contractor shall immediately pay Owner (directly or by offset, at Owner’s sole discretion) all costs and expenses incurred in performing such Punchlist Work. Upon Contractor’s request, Owner shall provide documentation identifying the costs incurred to perform such Punchlist Work.

12.6 Notice and Requirements for Final Completion. Final Completion shall be achieved when all requirements for Final Completion under this Agreement, including those set forth in the definition of Final Completion under Section 1.1, have been satisfied. Upon Final Completion, Contractor shall certify to Owner in the form of Attachment N (“Final Completion Certificate”) that all of the requirements under this Agreement for Final Completion have occurred. Owner shall notify Contractor whether it accepts or rejects the Final Completion Certificate within fifteen (15) Days following Owner’s receipt thereof. Acceptance of such certificate shall be evidenced by Owner’s signature on such certificate, which shall be forwarded to Contractor with such notice. If Owner does not agree that Final Completion has occurred, then Owner shall state the basis for its rejection in reasonable detail in a written notice provided to Contractor. The Parties shall thereupon promptly and in good faith confer and make all reasonable efforts to resolve such issue. In the event such issue is not resolved within ten (10) Business Days of the delivery by Owner of its notice, Owner and Contractor shall resolve the Dispute in accordance with the dispute resolution procedures provided for under Article 19; provided, however, if such deficiencies relate to the failure to complete Punchlist items, Owner may, in addition to any other rights that it may have under this Agreement, at law or in equity, complete such Punchlist Work at the expense of Contractor in accordance with Section 12.5.

12.7 Performance Guarantees as a Condition of Final Completion. As a condition of achieving Final Completion, each and every Unit shall achieve all Performance Guarantees and the Starting Reliability Requirement as described in greater detail in this Section 12.7. The Performance Tests for determining whether a Unit achieves the Performance Guarantees and the Starting Reliability Requirement are described in Attachment S and Attachment T.

A. Performance Guarantees Not Achieved. In the event that any Unit meets all of the Minimum Acceptance Criteria but fails to achieve one or more of the Performance Guarantees, as evidenced by the Performance Test results, then, at Contractor’s election, Contractor shall, with respect to each Performance Guarantee not achieved: (i) pay (directly, by offset, or by collection on the Contractor Letter of Credit, at Owner’s sole discretion) to Owner the applicable Performance Liquidated Damages for such Performance Guarantee; or (ii) take corrective actions to achieve such Performance Guarantee, provided that in the event such corrective actions do not result in the achievement of such Performance Guarantee within one hundred eighty (180) Days after achievement of Substantial Completion (or such longer period as Owner may allow), then Contractor shall pay (directly, by offset, or by collection on the Contractor Letter of Credit, at Owner’s sole discretion) to Owner the applicable Performance Liquidated Damages; provided further, however, in Owner’s reasonable discretion and in lieu of Contractor’s decision to pay Performance Liquidated Damage pursuant to clause (i) or (ii) above, Owner may require Contractor to perform curative Work in an attempt to achieve the failed Performance Guarantee(s), in which case all reasonable, direct costs incurred by Contractor in the performance of the curative Work, up to the value of the foregone Performance Liquidated Damages, shall be borne by Contractor and all reasonable, direct costs incurred by Contractor thereafter for the curative Work shall be reimbursed by Owner. The Performance Liquidated Damages shall be calculated in accordance with Attachment T.

B. Access During Performance of Curative Work. During any period of time in which Contractor is attempting to perform curative Work to achieve the Performance Guarantees as set forth in Section 12.7A, Owner shall provide Contractor with reasonable access to the applicable Unit sufficient for Contractor to perform its curative Work, subject to any reasonable security or safety requirements of Owner; provided, however, Owner shall be under no obligation to provide any access to Contractor that would interfere with the operation of the Facility or the Mirant Delta Facility; provided further, however, that if Owner denies Contractor reasonable access to the applicable Unit, then Contractor shall be entitled to an extension to the 180-Day period set forth in Section 12.7A for each Day that Owner so denies Contractor such reasonable access. Any such extension shall be set forth in a Change Order executed by the Parties. Contractor shall provide at least one (1) week’s prior written notice to Owner if performance of the curative Work could interfere with the operation of the Facility or the Mirant Delta Facility, in which case Owner, in its sole discretion, may place reasonable limitations on Contractor’s access to the Facility such that performance of the Work will cause no disruption to the operation of the Facility or the Mirant Delta Facility at the Site and no unreasonable loss of revenue to Owner.

C. Starting Reliability Requirement. In the event that any Unit fails to achieve the Starting Reliability Requirement, as evidenced by the Performance Test results for the Starting Reliability Requirement, then such failure shall be considered a Defect in accordance with Article 13 and Contractor and Owner shall have the rights and obligations set forth therein with respect to correcting such Defect. For the avoidance of doubt, achievement of the Starting Reliability Requirement is a material obligation under the Agreement.

12.8 ***

12.9 Partial Occupancy and Use. Prior to Contractor’s achieving Substantial Completion, Owner may occupy or use all or any portion of the Work then capable of functioning safely, provided that such occupancy or use is authorized by the Governmental Instrumentality and Owner’s insurance company or companies providing property insurance and builder’s risk coverage have consented to such partial occupancy or use. Contractor shall assist Owner and take reasonable steps in obtaining consent of the insurance company or companies and applicable Government Instrumentalities. Immediately prior to such partial occupancy or use, Owner and Contractor shall jointly inspect the area to be occupied or portion of the Work to be used in order to determine and record the condition of the Work and all personnel and environmental safety aspects of the Work. Such occupancy or use shall not in any way release Contractor or any surety of Contractor from any obligations or liabilities pursuant to this Agreement, including the obligation to engineer, procure and construct the Facility in accordance with all requirements of this Agreement; provided, however, Contractor shall be entitled to a Change Order for an extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, and adjustment to the Contract Price, to the extent Owner’s partial occupancy or use of the Facility delays the prosecution or completion of the Work, or increases Contractor’s cost of performing the Work, and Contractor satisfies the requirements for such time extension and Contract Price adjustment pursuant to Section 6.8. Such occupancy or use shall not be deemed to be an acceptance by Owner of such portion of the Facility.

12.10 Long-Term Obligations. No acceptance by Owner of any or all of the Work or any other obligations of Contractor under this Agreement, including acceptance of Mechanical Completion, Substantial Completion or Final Completion, nor any payment made hereunder, whether an interim or final payment, shall in any way release Contractor or any surety of Contractor from any obligations or liability pursuant to this Agreement, including obligations with respect to unperformed obligations of this Agreement or for any Work that does not conform to the requirements of this Agreement, including Warranty obligations, any liabilities for which insurance is required or any other responsibility of Contractor, including the payment of any and all fines and penalties assessed as a result of Contractor’s failure to comply with any Applicable Law. It is expressly understood and agreed by the Parties that nothing in this Article 12 shall in any way modify or alter Contractor’s obligations under Article 13 and Article 14 hereof.

ARTICLE 13

WARRANTY AND CORRECTION OF WORK

13.1 Warranty.

A. General. The warranties set forth in this Article 13 (collectively, the “Warranty” or “Warranties”) are in addition to any of the Minimum Acceptance Criteria or Performance Guarantees set forth in this Agreement. Any Work, or component thereof, that is not in conformity with any Warranty is defective (“Defective”) and contains a defect (“Defect”).

B. Warranty of Work. Contractor hereby warrants that the Work, including Equipment, and each component thereof shall be:

1. new, complete, and of suitable grade for the intended function and use;

2. in accordance with all of the requirements of this Agreement, including in accordance with GECP, Applicable Law and Applicable Codes and Standards;

3. free from encumbrances to title, as set forth in greater detail in Section 9.1; and

4. free from defects in design, material and workmanship.

C. Assignment and Enforcement of Subcontractor Warranties. Contractor shall, without additional cost to Owner, obtain warranties from Subcontractors and Sub-subcontractors that meet or exceed the requirements of this Agreement; provided, however, Contractor shall not in any way be relieved of its responsibilities and liability to Owner under this Agreement, regardless of whether such Subcontractor or Sub-subcontractor warranties meet the requirements of this Agreement, as Contractor shall be fully responsible and liable to Owner for its Warranty and Corrective Work obligations and liability under this Agreement for all Work. All such warranties shall be deemed to run to the benefit of Owner and Contractor. Such warranties, with duly executed instruments assigning the warranties to Owner, shall be delivered to Owner upon Substantial

Completion. All warranties provided by any Subcontractor or Sub-subcontractor shall be in such form as to permit direct enforcement by Contractor or Owner against any Subcontractor or Sub-subcontractor whose warranty is called for, and Contractor agrees that: (i) Contractor’s Warranty, as provided under this Article 13, shall apply to all Work regardless of the provisions of any Subcontractor or Sub-subcontractor warranty, and such Subcontractor or Sub-subcontractor warranties shall be in addition to, and not a limitation of, such Contractor Warranty; (ii) Contractor is jointly and severally liable with such Subcontractor or Sub-subcontractor with respect to such Subcontractor or Sub-subcontractor warranty; and (iii) service of notice on Contractor that there has been a breach of a Subcontractor or Sub-subcontractor warranty shall be sufficient to invoke the terms of the instrument. This Section 13.1C shall not in any way be construed to limit Contractor’s liability under this Agreement for the entire Work or its obligation to enforce Subcontractor warranties.

D. Exceptions to Warranty. The Warranty excludes remedy, and Contractor shall have no liability to Owner, for damage or defect to the extent caused by: (i) improper repairs or alterations, misuse, neglect or accident by Owner; (ii) operation, maintenance or use of Work or any component thereof in a manner not in compliance with a material requirement of operation and maintenance manuals delivered by Contractor to Owner; or (iii) normal wear and tear.

13.2 Inspection.

A. General Rights. All Work shall be subject to inspection by Owner, Lender and either of their representatives at all times to determine whether the Work conforms to the requirements of this Agreement. Contractor shall furnish Owner, Lender and either of their representatives with access to all locations where Work is in progress, including locations not on the Site. Prior to Substantial Completion, if any Work is Defective, then Contractor shall, at its own expense, promptly correct such Defective Work and any other portions of the Facility damaged or affected by such Defective Work, whether by repair, replacement or otherwise (including any and all obligations in connection with such repair, modification, re-performance or replacement, such as in and out costs, transportation costs, and any other costs necessary to fully correct the Work). Subject to Contractor’s right to pursue a dispute under Article 19, the decision of Owner shall be conclusive as to whether the Work is conforming or Defective, and Contractor shall comply with the instructions of Owner in all such matters while pursuing any such dispute. If it is later determined that the Work was not Defective, then Owner shall reimburse Contractor for all costs incurred in connection with such repair or replacement and a Change Order shall be issued for such amount and shall address any impact the repair or replacement may have had on the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable. If Contractor fails, after a reasonable period of time not to exceed one (1) week, to repair or replace any Defective Work, or to commence to repair or replace any Defective Work and thereafter continue to proceed diligently to complete the same, then Owner may repair or replace such Defective Work and the expense thereof shall be paid by Contractor (whether directly, by offset, or collection on the Contractor Letter of Credit, at Owner’s sole discretion).

B. Witness Points. Contractor shall provide Owner a proposed list of witness points for each item of Equipment for Owner’s review and prior written approval no later than thirty (30) Days’ after placement of the applicable Subcontract for such item of Equipment (or, with respect to the Siemens Contract, thirty (30) Days after the Effective Date), and Owner shall notify Contractor which of the witness points it or its Lenders’ representatives wish to witness. Contractor shall provide Owner with at least five (5) Business Days’ prior written notice of the actual scheduled date of each of the tests Owner has indicated it or its Lenders’ representatives wish to witness. Contractor shall cooperate with Owner if Owner or its Lenders’ representatives elect to witness any additional tests, and Contractor acknowledges that Owner and its Lenders’ representatives shall have the right to witness all tests being performed in connection with the Work. Owner’s rights of inspection (and the rights given to the Lenders’ representatives) as set forth herein apply only to their witnessing of witness points for Equipment and shall not be construed to imply a limitation on Owner’s right to inspect any portion on the Work (including Equipment) at any time in accordance with this Agreement.

C. No Obligation to Inspect. Owner’s or Lender’s right to conduct inspections under Sections 13.2A and 13.2B shall not obligate Owner or Lender to do so. Neither the exercise of Owner or Lender of any such right, nor any failure on the part of Owner or Lender to discover or reject Defective Work shall be construed to imply an acceptance of such Defective Work or a waiver of such Defect.

D. Cost of Disassembling. The cost of disassembling, dismantling or making safe finished Work for the purpose of inspection, and reassembling such portions (and any delay associated therewith) shall be borne by Owner if such Work is found to conform with the requirements of this Agreement and by Contractor if such Work is found to be Defective.

13.3 Correction of Work After Substantial Completion. If, after Substantial Completion but prior to the expiration of the Defect Correction Period, any Work is found to be Defective, Contractor shall, at its sole cost and expense, immediately and on an expedited basis (i) correct such Defective Work, whether by repair, replacement or otherwise, as determined by Contractor (including any and all obligations in connection with such repair, modification, re-performance or replacement of the Defect, such as in and out costs, transportation costs, and any other costs necessary to fully correct the Defective Work) and (ii) subject to Contractor’s limitations of liability set forth in Section 9.2B, correct, and, if Owner performs any or all of the correction, be liable for Owner’s costs and expenses to correct, any other portions of the Facility damaged or affected by such Defective Work, whether by repair, replacement or otherwise (collectively, clauses (i) and (ii) shall be the “Corrective Work”). Owner shall provide Contractor with access to the Facility sufficient to perform its Corrective Work, so long as such access does not unreasonably interfere with the construction or operation of the Facility or the Mirant Delta Facility and subject to any reasonable security or safety requirements of Owner. In the event Contractor utilizes spare parts owned by Owner in the course of performing the Corrective Work, Contractor shall supply Owner free of charge with new spare parts equivalent in quality and quantity to all such spare parts used by Contractor as soon as possible following the utilization of such spare parts.

A. Owner Right to Correct or Complete Defective Work. If Contractor fails to commence the Corrective Work within a reasonable period of time not to exceed ten (10) Days, or does not complete such Corrective Work on an expedited basis, then Owner, by written notice to Contractor, may (in addition to any other remedies that it has under this Agreement) correct such Defective Work, and Contractor shall be liable to Owner for all reasonable costs and expenses incurred by Owner in connection with correcting such Defective Work and arising out of or relating to such Defective Work and shall pay Owner (directly, by offset or by collection on the Contractor Letter of Credit, at Owner’s sole discretion) an amount equal to such reasonable costs and expenses; provided, however, if such Defective Work materially affects the construction, operation or use of any of the Work or the Facility or the Mirant Delta Facility or presents an imminent threat to the safety or health of any Person and Owner knows of such Defective Work, Owner may (in addition to any other remedies that it has under this Agreement) correct such Defective Work without giving prior written notice to Contractor (but shall give prompt notice to Contractor thereafter), and, in such event, Contractor shall be liable to Owner for all reasonable costs and expenses incurred by Owner in connection with correcting such Defective Work and arising out of or relating to such Defective Work and shall pay Owner (directly, by offset or by collection on the Contractor Letter of Credit, at Owner’s sole discretion) an amount equal to such reasonable costs and expenses (which costs and expenses shall be adequately documented and supported by Owner).

B. Standards for Corrective Work. All Corrective Work shall be performed subject to the same terms and conditions under this Agreement as the original Work is required to be performed. Any change to parts or Equipment that would alter the requirements of this Agreement may be made only with prior written approval of Owner.

C. Subject to Section 13.4, nothing contained in this Section 13.3 shall be construed to establish a period of limitation with respect to other obligations which Contractor might have under the Agreement.

13.4 Exclusivity. ***

13.5 Assignability of Warranties. The Warranties made in this Agreement shall be for the benefit of Owner and its successors and assigns and the respective successors and assigns of any of them, and are fully transferable and assignable.

ARTICLE 14

SUBSTANTIAL COMPLETION DELAY LIQUIDATED DAMAGES AND PAYMENT OF LIQUIDATED DAMAGES

14.1 Delay in Substantial Completion. If Substantial Completion for the Facility occurs after the Guaranteed Substantial Completion Date, Contractor shall pay to Owner delay liquidated damages (the “Substantial Completion Delay Liquidated Damages”) in the amounts for each full Day of delay until Substantial Completion occurs: ***.

14.2 Suspension or Cessation of Substantial Completion Delay Liquidated Damages. Notwithstanding the assessment of Substantial Completion Delay Liquidated Damages

in accordance with Section 14.1, but subject always to the assessment of Substantial Completion Delay Liquidated Damages in accordance with Section 12.4C, Substantial Completion Delay Liquidated Damages shall cease to accrue, even though Substantial Completion has not yet been achieved, (i) on an on-going, permanent basis starting upon the earlier of the Day that (a) Owner is notified in writing by PG&E that PG&E has certified the Facility to have achieved commercial operation under the power purchase agreement between Owner and PG&E or (b) the Facility has been placed in commercial operation (for operation other than for commissioning, testing or tuning), whether under the power purchase agreement between Owner and PG&E or any other commercial arrangement, for more than one hundred (100) Equivalent Operating Hours in the aggregate and (ii) on a temporary basis, for any particular Day in which the Facility is placed into commercial operation (for operation other than for commissioning, testing or tuning) under the power purchase agreement between Owner and PG&E or any other commercial arrangement.

14.3 Payment of Liquidated Damages. With respect to any Liquidated Damages that accrue, Owner, at its sole discretion, may either (i) invoice Contractor for such owed Liquidated Damages, and within thirty (30) Days of Contractor’s receipt of such invoice, Contractor shall pay Owner Liquidated Damages, (ii) withhold from Contractor amounts that are otherwise due and payable to Contractor in the amount of such Liquidated Damages, or (iii) collect on the Contractor Letter of Credit in the amount of such Liquidated Damages.

ARTICLE 17

DEFAULT, TERMINATION AND SUSPENSION

17.1 Default by Contractor.

A. Events of Default. If Contractor shall at any time (i) materially fail to prosecute the Work in accordance with the Agreement; (ii) abandon the Work; (iii) fail to comply with Sections 10.2, 10.3, 12.4A, 22.7, or 22.8; (iv) fail to maintain insurance required under this Agreement; (v) fail to discharge liens filed by any Subcontractor or Sub-subcontractor as required under this Agreement; (vi) cause, by any action or omission, any material stoppage or delay of or interference with the work or operations of Owner or its other contractors or subcontractors; (vii) have a material violation of Applicable Law or Applicable Codes and Standards; (viii) materially fail to comply with any provision of this Agreement; (ix) fail to develop a Recovery Schedule in accordance with Section 5.5; (x) after a Recovery Schedule is implemented in accordance with Section 5.5, (a) update the Monthly Updated CPM Schedule showing completion of any remaining Key Milestone to be delayed beyond the applicable Key Milestone Date by more than the number of Days set forth in column 4 of Attachment E for such Key Milestone or (b) fail to provide an updated Monthly Updated CPM Schedule to the Owner in accordance with the Agreement and Owner notifies Contractor in writing that it has reasonably determined (based upon objective criteria) that achievement of any Key Milestone will be delayed beyond the applicable Key Milestone Date by more than the number of Days set forth in column 4 of Attachment E for such Key Milestone; (xi) fail to complete a Key Milestone within the number of Days set forth in column 4 of Attachment E after the passing of the applicable Key Milestone Date; or (xii) itself, or Kiewit Construction Company, becomes insolvent, has a receiver appointed, makes a general assignment or filing for the benefit of its creditors or files for bankruptcy protection, or be unable to pay its debts when due (each of the foregoing in clauses (i) through (xii) being a “Default”), then Owner may provide Contractor with written notice that Contractor is in Default; provided, however, Contractor shall not be considered in Default under clause (x) or (xi) above if Contractor can reasonably demonstrate to Owner, via the Monthly Updated CPM Schedule developed in accordance with the requirements of this Agreement (including GECP), that Contractor will achieve Substantial Completion no later than the number of Days set forth in column 4 of Attachment E beyond the Guaranteed Substantial Completion Date for the Key Milestone in column 1 of Attachment E which has been missed (per clause (xi) above) or which is scheduled to be missed (per clause (x) above); provided further, however, if two or more Key Milestones are delayed such that Contractor would otherwise be considered in Default in accordance with clause (x) or (xi) above, then the longest applicable duration in column 4 of Attachment E for the delayed Key Milestones shall determine the number of

Days within which Contractor must reasonably demonstrate to Owner that Substantial Completion will be achieved after the Guaranteed Substantial Completion Date in order to avoid being considered in Default under this Section 17.1A. ***.

B. Cure Period for Defaults and Termination for Default. With respect to a Default under any of clauses (i), (ii), (iv), (vi), (vii), (viii) and (ix) in Section 17.1A, and following Owner’s written notice to Contractor specifying the general nature of such Default, Contractor shall cure such Default within thirty (30) Days, or if the Default cannot be cured with the exercise of reasonable diligence within such thirty (30) Days, Contractor shall immediately commence corrective action and cure such Default as expeditiously as feasible given the nature of the Default and the cure. If (i) Contractor fails to cure a Default occurring under any of the aforementioned clauses in accordance with the preceding sentence, or (ii) Contractor is in Default pursuant to clause (iii), (v), (x), (xi) or (xii) of Section 17.1A, then Owner, at its sole discretion and without prejudice to any other rights that it has under this Agreement, at law or in equity and without further notice to Contractor, may (1) take such steps as are necessary to overcome the Default condition, in which case Contractor shall be liable to Owner for any and all costs, damages, losses and expenses (including all attorneys’ fees, consultant fees and litigation expenses) incurred by Owner in connection therewith, (2) terminate for Default Contractor’s performance of all or any part of the Work, or (3) seek specific performance or interlocutory mandatory injunctive relief requiring performance of Contractor’s obligations, it being agreed by Contractor that such relief may be necessary to avoid irreparable harm to Owner. Notwithstanding the foregoing, if the Guaranteed Substantial Completion Date has passed, Contractor shall not be considered in Default pursuant to clause (x) or (xi) of Section 17.1A as long as Contractor is paying Substantial Completion Delay Liquidated Damages and has not reached its limitation of liability for such Substantial Completion Delay Liquidated Damages pursuant to Section 21.2A; provided, however, that after Contractor has paid Substantial Completion Delay Liquidated Damages up to the limitation of liability set forth in Section 21.2A, or if Contractor fails to pay Substantial Completion Delay Liquidated Damages when due, and Substantial Completion has not been achieved, Owner shall have the right to declare Contractor in Default pursuant to clause (x) or (xi) of Section 17.1A (as applicable).

C. Additional Rights of Owner Upon Termination. In the event that Owner terminates this Agreement for Default in accordance with Section 17.1A, Owner may, at its sole option, (i) enter onto the Site and, for the purpose of completing the Work, take possession of the information, documents and Books and Records for the Work, (ii) take assignment of any or all of the Subcontracts, and/or (iii) complete the Work either itself or through others. Contractor shall leave all third-party rented equipment, materials, tools, supplies, scaffolding, machinery and other items at the Site in place upon a termination in accordance with Section 17.1A unless otherwise requested by Owner and shall cooperate with such third-party rentors in the assignment of the rental Subcontract to Owner. If the unpaid balance of the Contract Price shall exceed all damages, costs, losses and expenses incurred by Owner (including all attorneys’ fees, consultant fees and litigation expenses, costs to complete the Work, Liquidated Damages and any and all damages for failure of performance and cost of financing or interest on such expense from the date such expense was incurred by Owner at the rate specified in Section 7.7), then such excess shall be paid

by Owner to Contractor, but such amount shall not be paid until after Final Completion has been achieved. If such amount incurred by Owner shall exceed the unpaid balance of the Contract Price, then, at Owner’s sole option, Contractor shall pay Owner the difference on demand, or Owner shall have the right and authority to offset or collect on the Contractor Letter of Credit in the amount of such difference. While subject to Contractor’s limitations of liability under Article 21, Contractor’s liability under this Section 17.1C is in addition to any other liability provided for under this Agreement and Owner shall have the right and authority to set off against and deduct from any such excess due Contractor by Owner any other liability of Contractor to Owner under this Agreement. Owner agrees to act reasonably to mitigate any costs it might incur in connection with any termination for Default. In the event of a termination for Default, the Parties agree that Owner shall be entitled to any and all damages, losses, costs and expenses incurred by Owner arising out of or resulting from such Default, including any and all Liquidated Damages; provided that Contractor’s aggregate liability shall apply to the extent provided by Section 21.1. If Contractor is terminated for Default pursuant to Section 17.1, the Parties agree that, for purposes of this Section 17.1C, and with respect to Substantial Completion that was not achieved by Contractor prior to such termination, Substantial Completion Delay Liquidated Damages owed by Contractor to Owner shall be based on the date that the substitute contractor achieved Substantial Completion.

D. Erroneous Termination for Default. If any termination for Default by Owner is found to be not in accordance with the provisions of this Agreement or is otherwise deemed to be unenforceable, then such termination for Default shall be deemed to be a termination for convenience as provided in Section 17.2.

E. Obligations Upon Termination. Upon termination for Default, Contractor shall (i) immediately discontinue Work on the date and to the extent specified in the notice, (ii) place no further orders for Subcontracts, Equipment, or any other items or services except as may be necessary for completion of such portion of the Work as is not discontinued, (iii) inventory, maintain and leave on-Site all third-party equipment, machinery, materials, tools, supplies and scaffolding rented by Contractor or provided by Owner for performance of the terminated Work, (iv) promptly make every reasonable effort to procure assignment or cancellation upon terms satisfactory to Owner of all Subcontracts and rental agreements to the extent they relate to the performance of the Work that is discontinued; (v) cooperate with Owner in the transfer of Work Product, including Drawings and Specifications, Permits, licenses and any other items or information and disposition of Work in progress so as to mitigate damages; (vi) if requested by Owner in writing, assign the PLA to Owner or such other Person as directed by Owner; (vii) comply with other reasonable requests from Owner regarding the terminated Work; (viii) thereafter execute only that portion of the Work not terminated (if any) and that portion of the Work as may be necessary to preserve and protect Work already in progress and to protect Equipment at the Site or in transit thereto, and to comply with any Applicable Law and any Applicable Codes and Standards; and (ix) perform all other obligations under Section 17.1C.

17.2 Termination for Convenience by Owner. Owner shall have the right to terminate for convenience Contractor’s performance of all or any part of the Work by providing Contractor

with a written notice of termination, to be effective upon receipt by Contractor. Upon termination for convenience, Contractor shall (i) immediately discontinue the Work on the date and to the extent specified in such notice, (ii) place no further orders for Subcontracts, Equipment, or any other items or services except as may be necessary for completion of such portion of the Work as is not discontinued, (iii) promptly make every reasonable effort to procure cancellation upon terms satisfactory to Owner of all Subcontracts and rental agreements to the extent they relate to the performance of the Work that is discontinued unless Owner elects to take assignment of any such Subcontracts, (iv) assist Owner in the maintenance, protection, and disposition of Work in progress, (v) cooperate with Owner for the efficient transition of the Work, (vi) cooperate with Owner in the transfer of Work Product, including Drawings and Specifications, Permits, licenses and any other items or information and disposition of Work in progress, (vii) if requested by Owner in writing, assign the PLA to Owner or such other Person as directed by Owner and (viii) thereafter execute only that portion of the Work not terminated (if any) and that portion of the Work as may be necessary to preserve and protect Work already in progress and to protect Equipment at the Site or in transit thereto, and to comply with any Applicable Law and Applicable Codes and Standards and Owner may, at its sole option, take assignment of any or all of the Subcontracts. Contractor shall be entitled to receive payment for: (1) if the Siemens Contract is terminated, the Siemens Termination Payment; plus (2) the difference between (A) the Work Cost (as defined below) and (B) the amounts Contractor has previously been paid under the Agreement for EPC Payment Milestones, including any down payments made by Owner (other than down payments made by Owner on account of the Siemens Contract) (this difference in clause (2) being the “Kiewit Termination Charge”). In no event shall Contractor be entitled to receive any amount for unabsorbed overhead, contingency, risk or anticipatory profit. Contractor shall submit its accounting of the Kiewit Termination Charge to Owner for verification and audit within sixty (60) Days following the effective date of termination. If no Work has been performed by Contractor at the time of termination, Contractor shall be paid the sum of One Hundred U.S. Dollars (U.S.$100) for its undertaking to perform. The Siemens Termination Payment and Kiewit Termination Payment shall be Owner’s sole liability to Contractor in the event of a termination under this Section 17.2.

A. The “Work Cost” shall mean the sum of (i) that part of the EPC Payment Milestone portion of the Contract Price that has been properly invoiced by Contractor under this Agreement for Work allocated to EPC Payment Milestones completed in accordance herewith prior to termination (as such amounts may be limited by the maximum cumulative payment amounts for which Contractor is able to invoice to Owner in a given Month for the EPC Payment Milestones, as further set forth in Schedule C-3) plus (ii) the Demobilization and Subcontract Cancellation Cost. The “Demobilization and Subcontract Cancellation Cost” shall mean the documented and reasonable costs (plus a profit of ***) incurred by Contractor to demobilize from the Site plus actual cancellation charges incurred by Contractor on any Subcontract terminated as a result of the terminated Work, all of which Contractor shall use commercially reasonable efforts to minimize; provided, however, notwithstanding the foregoing, the Demobilization and Subcontract Cancellation Cost shall not exceed the Maximum Demobilization and Subcontract Cancellation Cost set forth in Schedule C-3 as determined by the Month in which the Agreement is terminated. For purposes of clarity, in the event of a termination for convenience under Section 17.2 and with respect to the invoices provided by Contractor pursuant to clause (i) above for EPC Payment Milestones completed prior to termination,

such invoices may include an invoice submitted by Contractor promptly after termination which accounts for EPC Payment Milestones completed between the last regularly submitted invoice and the date of termination.

17.3 Suspension of Work. Owner may, for any reason, at any time and from time to time, by written Owner-directed or mutual Change Order, suspend the carrying out the Work or any part thereof, whereupon Contractor shall suspend the carrying out of such suspended Work for such time or times and in such manner as Owner may require and shall take reasonable steps to minimize any costs associated with such suspension; provided, however, with respect to any suspension of Work being performed under the Siemens Contract, the Parties acknowledge that such suspension of Work shall be subject to the conditions on suspension set forth in Section 10.2.2 of the Siemens Contract and Contractor’s directives to, or agreements with, Siemens with respect to suspension of any Work under the Siemens Contract shall be subject to Owner’s written approval. During any suspension, Contractor shall properly protect and secure such suspended Work in accordance with GECP. Unless otherwise instructed by Owner, Contractor shall during any such suspension maintain its staff and labor on or near the Site and otherwise be ready to proceed expeditiously with the Work upon receipt of Owner’s further instructions. Except where such suspension ordered by Owner is the result of or due to the fault or negligence of Contractor or any Subcontractor or Sub-subcontractor, Contractor shall be entitled to the reasonable costs (including actual, but not unabsorbed, overhead, contingency, escalation, and risk and a profit of ***) of such suspension, including demobilization and remobilization costs, if necessary, along with appropriate supporting documentation to evidence such costs, and a time extension to the Key Milestone Schedule, Guaranteed Substantial Completion Date and Required Final Completion Date, as applicable, if and to the extent permitted under Section 6.8. Upon receipt of notice to resume suspended Work, Contractor shall immediately resume performance of the Work to the extent required in the notice; provided, however, with respect to resumption of suspended Work being performed under the Siemens Contract, such resumption of Work shall be further subject to the conditions and considerations set forth in Section 10.2.2 of the Siemens Contract. In no event shall Contractor be entitled to any additional profits or damages due to such suspension.

17.4 Suspension by Contractor. Notwithstanding anything to the contrary in this Agreement, Contractor shall have the responsibility at all times to prosecute the Work diligently and shall not suspend, stop or cease performance hereunder or permit the prosecution of the Work to be delayed; provided, however, subject to Owner’s right to withhold or offset payment to Contractor under this Agreement, if Owner fails to pay undisputed amounts due and owing to Contractor, and Owner has failed to cure such failure within fifteen (15) Days following Contractor’s written notice to Owner to cure such failure, Contractor may suspend performance of the Work until Contractor receives such undisputed amounts.

17.5 Termination by Contractor. Contractor may terminate this Agreement if, continuing at the time of such termination, Contractor has stopped the performance of all Work under this Agreement pursuant to Section 17.4 for thirty (30) Days, and after the expiration of such thirty (30) Day period, Contractor gives Owner written notice specifying the nature of the default and its intent to terminate the Agreement, and Owner fails to cure such default within fifteen (15) Days after receipt of Contractor’s notice. In addition, if Owner has suspended all Work pursuant to Section 17.3 and such suspension has lasted beyond three hundred sixty five (365) Days, Contractor shall have the right, upon written notice to Owner, to terminate the Agreement. In the

event of any such termination under this Section 17.5, Contractor shall have the rights (and Owner shall make the payments) provided for in Section 17.2 in the event of an Owner termination for convenience. Contractor’s sole rights to terminate this Agreement are set forth in Sections 17.5 and 17.6.

17.6 Termination in the Event of Extended Force Majeure. If a Force Majeure occurring after issuance of NTP causes Contractor to suspend performance of all the Work for a period exceeding *** Days, either Party may, upon thirty (30) Days prior written notice to the other Party stating its intentions, terminate the Agreement. Termination of the Agreement in accordance with this Section 17.6 shall cause the Parties to have the rights and obligations as if such termination was initiated pursuant to Section 17.2; provided, however, and notwithstanding anything to the contrary, Owner shall not be responsible for the Siemens Termination Payment or the Kiewit Termination Charge in the event of a termination in accordance with this Section 17.6, and Contractor’s sole remedy, and Owner’s sole obligations, with respect to payment for such termination shall be payment for the Work performed, up to the date of termination, in accordance with Section 7.2.

LIMITATION OF LIABILITY

21.1 Contractor Aggregate Liability. ***

C. Exceptions to Limitations of Liability Under Section 21.2. Sections 21.2A and 21.2B shall not be construed to limit Contractor’s other obligations or liabilities under this Agreement (including (i) its obligations to complete the Work for the compensation provided under this Agreement, (ii) its obligations to achieve Substantial Completion and Final Completion and (iii) its obligations with respect to Minimum Acceptance Criteria and Warranties).

21.3 Liquidated Damages In General.

A. Liquidated Damages Not Penalty. It is expressly agreed that Liquidated Damages payable under this Agreement do not constitute a penalty and that the Parties, having negotiated in good faith for such specific Liquidated Damages and having agreed that the amount of such Liquidated Damages is reasonable in light of the anticipated harm caused by the breach related thereto and the difficulties of proof of loss and inconvenience or nonfeasibility of obtaining any adequate remedy, are estopped from contesting the validity or enforceability of the per Day rate of the Substantial Completion Delay Liquidated Damages and the per unit rate for the Performance Liquidated Damages on the basis that such per Day rate or per unit rate constitutes a penalty. In the event Contractor, Kiewit Construction Company, or anyone on their behalf, successfully challenges the enforceability of the per day rate of any Substantial Completion Delay Liquidated Damages or the per unit rate of any Performance Liquidated Damages on the basis of being a penalty, Contractor specifically agrees to pay Owner all actual damages incurred by Owner in connection with such breach, plus reasonable costs incurred by Owner in proving the same, without regard to any limitations whatsoever set forth in the Agreement other than (with respect to a challenge to the Substantial Completion Delay Liquidated Damages) the cap on Substantial Completion Delay Liquidated Damages specified in Section 21.2A or (with respect to a challenge to the Performance Liquidated Damages) the cap on Performance Liquidated Damages specified in Section 21.2B; provided that the reimbursement of reasonable costs incurred by Owner in proving its actual damages (as set forth above) shall not be included within the foregoing caps.

B. Liquidated Damages as Exclusive Damages. Payment of any Liquidated Damages with respect to any Work shall be in addition to, and not in lieu of, Contractor’s other obligations under this Agreement and shall in no way affect Owner’s right to

terminate this Agreement under Article 17 or receive other Liquidated Damages or remedies contemplated in this Agreement for any other aspect of Contractor’s obligations hereunder. Notwithstanding the foregoing and without limitation of Owner’s rights under Sections 17.1 or 21.3A:

1. Substantial Completion Delay Liquidated Damages shall be the sole damages owed by Contractor for delay in achieving Substantial Completion as set forth in Section 14.1; and

2. Performance Liquidated Damages shall be the sole damages owed by Contractor for failure of the Work to achieve any of the Performance Guarantees.

21.4 Consequential Damages. ***

NOW THEREFORE, in consideration of the mutual covenants herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

1. Guarantee.

(a) On the terms and subject to the conditions contained herein, Guarantor hereby irrevocably guarantees, to and for the benefit of Owner, the full and punctual performance and payment, as and when each such payment or performance becomes due (whether at the stated due date, by acceleration or otherwise), by or on behalf of Contractor of any and all obligations or amounts owed by Contractor to Owner in connection with and to the extent provided for in the Agreement (the “Guaranteed Obligations”). The Guaranteed Obligations of Guarantor hereunder are direct and primary obligations.

(b) This Guarantee is a present, and continuing guarantee of performance and payment, and not of collection, is in no way conditioned or contingent upon any attempt to collect from or enforce performance or payment by Contractor, and shall remain in full force and effect and be binding upon and against Guarantor and its successors and permitted assigns (and shall inure to the benefit of Owner and its permitted successors, permitted endorsees, permitted transferees, and permitted assigns). If Contractor shall fail or be unable duly, punctually, and

Z-2

fully to perform or pay, as and when such performance or payment is due, any of the Guaranteed Obligations, and taking into account any grace period applicable with respect thereto under the Agreement, then upon receipt of written notice from Owner specifying the failure, Guarantor shall promptly perform or pay, or cause to be performed or paid, such Guaranteed Obligations as required pursuant to the terms and conditions of the Agreement.

(c) Guarantor agrees that any final judgment from any final award resulting from any litigation between Contractor and Owner under the Agreement (whether in contested litigation, by default or otherwise) shall be conclusive and binding on the Parties for the purposes of determining Guarantor’s obligations under the Guarantee.

2. Obligations Continuing.

(a) Guarantor agrees that the obligations of Guarantor set forth in this Guarantee shall be direct obligations of Guarantor, and that such obligations shall be irrevocable, and that except for those specific defenses which Contractor would be entitled to assert if an action or proceeding to enforce such obligations were to be asserted or instituted against Contractor based upon the Agreement (which defenses Guarantor hereby retains and is authorized to assert), including any limitation of liability under Section 21.1 of the Agreement, this Guarantee shall not be subject to any counterclaim, set-off, deduction, diminution, abatement, recoupment, suspension, deferment, reduction or defense (other than full and strict compliance with its obligations hereunder) based upon any claim Guarantor or any other Person may have against Owner or any other Person and shall remain in full force and effect without regard to and shall not be released, discharged or in any way affected or impaired by, any circumstance or condition whatsoever (other than full and strict compliance by Guarantor with its obligations hereunder) (whether or not Guarantor shall have any knowledge or notice thereof), including, without limitation: (i) any amendment or modification of or supplement to or other change in the Agreement or any other document to which Contractor or its permitted assigns are a party, including, without limitation, any change order, renewal, extension, acceleration or other changes to payment terms thereunder; (ii) any waiver, consent, extension, indulgence, compromise, release or other action or inaction under or in respect of the Agreement or any other related document or any related obligation or liability of Owner or Contractor, or any exercise or non-exercise of any right, remedy, power, or privilege under or in respect of any such instrument or agreement or any such obligation or liability; (iii) any bankruptcy, insolvency, reorganization, arrangement, readjustment, liquidation, or similar proceeding with respect to Owner, Contractor, or any other Person or any of their respective properties, or any action taken by any trustee or receiver or by any court in any such proceeding; (iv) any merger or consolidation of Guarantor or Contractor into or with any other Person or any sale, lease, or transfer of all or any of the assets of Guarantor or Contractor; (v) any change in the ownership of Guarantor, Contractor, or any other Person; (vi) any winding up or dissolution of Contractor; or (vii) to the extent permitted under Applicable Law, any other occurrence or circumstance whatsoever, whether similar or dissimilar to the foregoing, which might otherwise constitute a legal or equitable defense or discharge of the liabilities of guarantor or surety or which might otherwise limit recourse against Guarantor. The Guaranteed Obligations constitute the full recourse obligations of Guarantor enforceable against it to the full extent of all its assets and properties. Without limiting the generality of the foregoing, Guarantor agrees that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, Contractor shall fail to

Z-3

perform obligations or pay amounts owed by Contractor under the Agreement and that notwithstanding the recovery hereunder for or in respect of any given failure to so comply by Contractor under the Agreement, this Guarantee shall remain in full force and effect and shall apply to each and every subsequent such failure.

(b) Notwithstanding any other language in this Guarantee to the contrary (but subject at all times to the exception set forth in this Section 2(b)), Guarantor’s obligations and liability under this Guarantee shall not differ from or exceed the obligations and liabilities of Contractor under the Agreement, nor shall the remedies available to Owner under this Guarantee extend beyond the remedies available to Owner against Contractor under the Agreement; provided that in no case shall this Section 2(b) be interpreted to relieve Guarantor of any Guaranteed Obligations or preclude any remedy available to Owner due to any of the circumstances in Sections 2(a)(iii) or 2(a)(vi).

3. Reinstatement. Guarantor agrees that this Guarantee shall be automatically reinstated with respect to any payment made by or on behalf of Contractor pursuant to the Agreement if and to the extent that such payment is rescinded or must be otherwise restored pursuant to Applicable Law, whether as a result of any proceedings in bankruptcy or reorganization or otherwise.

4. Waiver of Demands, Notices. Guarantor hereby unconditionally waives, to the extent permitted by Applicable Law: (i) notice of any of the matters referred to in Section 2 hereof; (ii) all notices which may be required by Applicable Law, or otherwise, now or hereafter in effect, to preserve any rights against Guarantor hereunder, including, without limitation, any demand, proof, or notice of non-payment or non-performance of any Guaranteed Obligation; (iii) notice of acceptance of this Guarantee, demand, protest, presentment, notice of failure of performance or payment, and any requirement of diligence; and (iv) any requirement to exhaust any remedies.

5. Waiver of Subrogation. Until such time as the Guaranteed Obligations are performed and paid in full, Guarantor shall not seek or be entitled to assert or enforce any right of contribution, reimbursement, indemnification or any other right to payment from Contractor as a result of Guarantor’s performance of its obligations pursuant to this Guarantee. If any funds or property shall be paid or transferred to Guarantor on account of such subrogation, contribution, reimbursement or indemnification at any time when all of the Guaranteed Obligations have not been performed and paid in full, Guarantor shall hold such funds or property in trust for Owner and shall forthwith pay over to Owner such funds and/or property to be applied by Owner to the Guaranteed Obligations, whether or not matured, in such order as Owner may determine.

6. Representations and Warranties. Guarantor represents and warrants that:

(a) it is a corporation duly organized and validly existing under the laws of the State of Delaware and has the corporate power and authority to execute, deliver and carry out the terms and provisions of the Guarantee;

(b) the execution, delivery and performance of this Guarantee will not conflict with, violate or breach the terms of any agreement of Guarantor;

Z-4

(c) no authorization, approval, consent or order of, or registration or filing with, any court or other governmental body having jurisdiction over Guarantor is required on the part of Guarantor for the execution and delivery of this Guarantee; and

(d) this Guarantee, when executed and delivered, will constitute a valid and legally binding agreement of Guarantor, except as the enforceability of this Guarantee may be limited by the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity as they apply to the Guarantor.

7. Miscellaneous.

(a) This Guarantee shall inure to the benefit of and be binding upon the Parties hereto and their respective successors and permitted assigns. Neither Party may assign or transfer this Guarantee or any rights or obligations hereunder without the other Party’s prior written consent. Notwithstanding the foregoing, this Guarantee may be assigned by Owner without the written consent of Guarantor (i) to assign, pledge and/or grant a security interest in, or payment obligation under this Guarantee or (ii) to the same extent that Owner is able to assign the Agreement pursuant to Section 22.7 therein. Except as provided in this Section 7, nothing herein, express or implied, is intended or shall be construed to confer upon or to give to any Person other than the Parties hereto any rights, remedies, or other benefits.

(b) This Guarantee shall be governed by, and construed in accordance with, the laws of the state of New York except for any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) other than Section 5-1401 of the New York General Obligations Law.

SCHEDULE Z-2

FORM OF OWNER’S PARENT GUARANTEE

This GUARANTEE (this “Guarantee”), dated as of [ ], is made by Mirant Corporation, a Delaware corporation (“Guarantor”), in favor of Kiewit Power Constructors Co. (“Contractor,” and, together with Guarantor, each a “Party” and, collectively, the “Parties”). Capitalized terms used, but not otherwise defined, herein shall have the respective meanings ascribed to such terms in the Agreement (as defined below).

RECITALS

WHEREAS, Contractor has agreed to enter into the Lump Sum Turnkey Agreement for the Engineering, Procurement and Construction of the Marsh Landing Generating Station, dated [ ] (the “Agreement”), with Mirant Marsh Landing, LLC (“Owner”), a subsidiary of Guarantor, which is hereby incorporated by reference in this Guarantee and made a part hereof, for the engineering, procurement and construction of a natural gas-fired electric generation facility located near Antioch, California; and

WHEREAS, Owner is a subsidiary of Guarantor;

WHEREAS, Guarantor is guaranteeing the payment obligations by Owner of the Kiewit Termination Charge (as such term is defined in Section 17.2 of the Agreement) owed by Owner to Contractor under the Agreement.

WHEREAS, it is a requirement within the Agreement that Guarantor execute and deliver this Guarantee.

NOW THEREFORE, in consideration of the promises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

1. Guarantee.

(a) On the terms and subject to the conditions contained herein, Guarantor hereby irrevocably guarantees, to and for the benefit of Contractor, the full and punctual payment of the Kiewit Termination Charge (as such term is defined in Section 17.2 of the Agreement) in the event of (i) a termination for convenience of the Agreement by Owner pursuant to Section 17.2 of the Agreement or (ii) a termination of the Agreement by Contractor pursuant to Section 17.5 of the Agreement, as and when such payment becomes due, by or on behalf of Owner in connection with and to the extent provided for in the Agreement (the “Guaranteed Obligations”); provided, however, notwithstanding anything to the contrary, Guarantor’s payment guarantee for such Guaranteed Obligations shall not exceed ***. The Guaranteed Obligations of Guarantor hereunder are direct and primary obligations.

(b) This Guarantee is a present, and continuing guarantee of payment, and not of collection, is in no way conditioned or contingent upon any attempt to collect from or enforce

Z-9

payment by Owner, and shall remain in full force and effect and be binding upon and against Guarantor and its successors and permitted assigns (and shall inure to the benefit of Contractor and its permitted successors, permitted endorsees, permitted transferees, and permitted assigns). If Owner shall fail or be unable duly, punctually, and fully to pay, as and when such payment is due, any of the Guaranteed Obligations, and taking into account any grace period applicable with respect thereto under the Agreement, then upon receipt of written notice from Contractor specifying that the Kiewit Termination Charge is due under Section 17.2 of the Agreement, Guarantor shall promptly pay, or cause to be paid, such Guaranteed Obligations as required pursuant to the terms and conditions of the Agreement.

(c) Guarantor agrees that any final judgment from any final award resulting from any litigation between Contractor and Owner under the Agreement with respect to the Guaranteed Obligations (whether in contested litigation, by default or otherwise) shall be conclusive and binding on the Parties for the purposes of determining Guarantor’s obligations under the Guarantee.

2. Obligations Continuing; Etc.

(a) Guarantor agrees that the obligations of Guarantor set forth in this Guarantee shall be direct obligations of Guarantor, and that such obligations shall be irrevocable, and that except for those specific defenses which Owner would be entitled to assert if an action or proceeding to enforce such obligations were to be asserted or instituted against Owner based upon the Agreement (which defenses Guarantor hereby retains and is authorized to assert), including the limitation of liability for this Guarantee under Section 10.5 of the Agreement, this Guarantee shall not be subject to any counterclaim, set-off, deduction, diminution, abatement, recoupment, suspension, deferment, reduction or defense (other than full and strict compliance with its obligations hereunder) based upon any claim Guarantor or any other Person may have against Contractor or any other Person and shall remain in full force and effect without regard to and shall not be released, discharged or in any way affected or impaired by, any circumstance or condition whatsoever (other than full and strict compliance by Guarantor with its obligations hereunder) (whether or not Guarantor shall have any knowledge or notice thereof), including, without limitation: (i) any amendment or modification of or supplement to or other change in the Agreement or any other document to which Owner or its permitted assigns are a party, including, without limitation, any change order, renewal, extension, acceleration or other changes to payment terms thereunder; (ii) any waiver, consent, extension, indulgence, compromise, release or other action or inaction under or in respect of the Agreement or any other related document or any related obligation or liability of Owner or Contractor, or any exercise or non-exercise of any right, remedy, power, or privilege under or in respect of any such instrument or agreement or any such obligation or liability; (iii) any bankruptcy, insolvency, reorganization, arrangement, readjustment, liquidation, or similar proceeding with respect to Owner, Contractor or any other Person or any of their respective properties, or any action taken by any trustee or receiver or by any court in any such proceeding; (iv) any merger or consolidation of Guarantor or Owner into or with any other Person or any sale, lease, or transfer of all or any of the assets of Guarantor or Owner; (v) any change in the ownership of Guarantor, Owner or any other Person; (vi) any winding up or dissolution of Owner; or (vii) to the extent permitted under Applicable Law, any other occurrence or circumstance whatsoever, whether similar or dissimilar to the foregoing, which might otherwise constitute a legal or equitable defense or discharge of the liabilities of

Z-10

guarantor or surety or which might otherwise limit recourse against Guarantor. The Guaranteed Obligations constitute the full recourse obligations of Guarantor enforceable against it to the full extent of all its assets and properties. Without limiting the generality of the foregoing, Guarantor agrees that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, Owner shall fail to pay the Guaranteed Obligations owed by Owner under the Agreement and that notwithstanding the recovery hereunder for or in respect of any given failure to so comply by Owner under the Agreement, this Guarantee shall remain in full force and effect and shall apply to each and every subsequent such failure.

(b) Notwithstanding any other language in this Guarantee to the contrary (but subject at all times to (i) the limitation of liability for the Guaranteed Obligations set forth in Section 1(a) and (ii) the exception set forth in this Section 2(b)), Guarantor’s obligations and liability for the Guaranteed Obligations under this Guarantee shall not differ from or exceed the obligations and liabilities of Owner under the Agreement, nor shall the remedies available to Contractor under this Guarantee extend beyond the remedies available to Contractor against Owner under the Agreement; provided that in no case shall this Section 2(b) be interpreted to relieve Guarantor of any Guaranteed Obligations or preclude any remedy available to Contractor due to any of the circumstances in Sections 2(a)(iii) or 2(a)(vi).

3. Reinstatement. Guarantor agrees that this Guarantee shall be automatically reinstated with respect to any payment made by or on behalf of Owner pursuant to the Agreement if and to the extent that such payment is rescinded or must be otherwise restored pursuant to Applicable Law, whether as a result of any proceedings in bankruptcy or reorganization or otherwise.

4. Waiver of Demands, Notices; Etc. Guarantor hereby unconditionally waives, to the extent permitted by Applicable Law: (i) notice of any of the matters referred to in Section 2 hereof; (ii) all notices which may be required by Applicable Law, or otherwise, now or hereafter in effect, to preserve any rights against Guarantor hereunder, including, without limitation, any demand, proof, or notice of non-payment of the Guaranteed Obligations; (iii) notice of acceptance of this Guarantee, demand, protest, presentment, notice of failure of payment, and any requirement of diligence; and (iv) any requirement to exhaust any remedies.

5. Waiver of Subrogation. Until such time as the Guaranteed Obligations are paid in full, Guarantor shall not seek or be entitled to assert or enforce any right of contribution, reimbursement, indemnification or any other right to payment from Owner as a result of Guarantor’s performance of its obligations pursuant to this Guarantee. If any funds or property shall be paid or transferred to Guarantor on account of such subrogation, contribution, reimbursement or indemnification at any time when all of the Guaranteed Obligations have not been paid in full, Guarantor shall hold such funds or property in trust for Contractor and shall forthwith pay over to Contractor such funds and/or property to be applied by Contractor to the Guaranteed Obligations, whether or not matured, in such order as Contractor may determine.

6. Representations and Warranties. Guarantor represents and warrants that:

Z-11

(b) the execution, delivery and performance of this Guarantee will not conflict with, violate or breach the terms of any agreement of Guarantor;

7. Miscellaneous.

(a) This Guarantee shall inure to the benefit of and be binding upon the Parties hereto and their respective successors and permitted assigns. Neither Party may assign or transfer this Guarantee or any rights or obligations hereunder without the other Party’s prior written consent. Notwithstanding the foregoing, this Guarantee may be assigned by Contractor to the same extent that Contractor is able to assign the Agreement pursuant to Section 22.7 therein. Except as provided in this Section 7, nothing herein, express or implied, is intended or shall be construed to confer upon or to give to any Person other than the Parties hereto any rights, remedies, or other benefits.

Z-12

understanding and agreement among the Parties hereto with respect to the subject matter hereof and cancels and supersedes any prior negotiations, proposals, representations, understandings, commitments, communications, or agreements, whether oral or written, with respect to the subject matter hereof.

ATTACHMENT AA

DEMOLITION WORK AND DEMOLITION INFORMATION

Contractor shall perform demolition Work and relocation of existing utilities and underground interferences pursuant to this Attachment AA.

General Scope of the Demolition Work:

Contractor shall demolish, excavate, load, remove from the Site and properly dispose of the existing foundations, concrete structures and other underground interferences at the Site (to the extent such other interferences have been identified by Owner either during inspections or in Schedule Y-3 or the drawings listed below), including the foundations for fuel oil tanks No. 1 through 5, equipment pads and pipe trenches. Such Work shall include the excavation, loading, removal and disposal of the sand and gravel matting under the fuel oil tanks. Drawings and information for the fuel oil tank foundations and other structures to be demolished and disposed of are provided in Schedule Y-3 and the drawings listed below.

Contractor shall demolish, excavate, load, remove from the Site and properly dispose of existing concrete and asphalt berms and other secondary containment structures as necessary for the construction of the Facility and to properly manage Site drainage. Drawings and information for the berms and other secondary containment structures are shown in Schedule Y-3 and the drawings listed below.

Contractor shall remove and relocate existing utilities at the Site as part of the demolition Work, including those utilities identified by the drawings and documents listed below and utilities identified by Contractor in its investigations as set forth in Section 5.2D of the Agreement. For clarity, all underground utilities east of the existing Fuel Oil Tanks #2 and #4 (and within the Site) shall be relocated and remain functional with the exception of the 480v cable runs to and from Load Center #8 (as shown on the Owner-provided drawings). The impound basin drain lines that run east of the Fuel Oil Tanks #2 and #4 berm (as shown in the Owner-provided drawings) shall be relocated if necessary. Also, the 3” PVC piping run supplying potable water, running in the fuel oil piping rack from Fuel Oil Tank #8 to the northeast corner of Fuel Oil Tank #2 and beyond, shall be removed and relocated. And the 4” PVC conduit carrying communication cable and running along the fuel oil piping rack from the northwest corner of Fuel Oil Tank #6 to the northeast corner of Fuel Oil Tank #2 and beyond shall also be removed but shall not be placed back into service by Contractor. (Owner shall be responsible for installing the new conduit and communications cable for the Facility; Contractor shall avoid damaging such new conduit and communications cable during the performance of the Work.) Note: The Parties acknowledge that the foregoing PVC piping runs are not shown on the drawings listed herein but have been identified to Contractor. All relocated utilities shall be returned to proper working order by Contractor.

Interfaces Regarding Loading, Removal and Disposal of Demolished Structures and Excavated Materials

Except as otherwise set forth in this Attachment AA, all demolished structures and utilities and excavated materials resulting from the demolition Work shall be loaded, removed from the Site (and relocated, as applicable) and otherwise properly disposed of by Contractor in accordance with the Agreement.

2.	If Contractor encounters pre-existing Hazardous Materials during the performance of the demolition Work (other than soil, including sand and gravel beneath the fuel oil tanks, containing oil-based compounds, including corrosion inhibiting oils), then Contractor shall proceed in accordance with

AA-1

Section 3.17 of the Agreement. After notification by Contractor to Owner of its encounter with the Hazardous Materials, Owner shall cause such Hazardous Materials to be remediated, removed from the Site and disposed of in a reasonably prompt manner.

If Contractor encounters soils (including sand and gravel beneath the fuel oil tanks) containing oil-based compounds (such as corrosion inhibiting oils) during the performance of the demolition Work, then Contractor will excavate such soil and load such soil onto Owner-provided trucks for disposal by Owner. If the amount of excavation necessary to remove this type of soil is greater than one foot deep of sand and gravel matting, then Contractor shall be entitled to a Change Order for the additional, direct costs incurred as a result of such additional excavation.

If Contractor encounters any groundwater contaminated by Hazardous Materials and such contaminated groundwater requires Contractor to provide additional, unanticipated treatment of such groundwater prior to its release or causes Contractor to provide temporary storage for such contaminated groundwater (for Owner’s subsequent treatment and disposal), then Contractor shall be entitled to a Change Order for the additional, direct costs incurred as a result of such additional water treatment or provision of temporary storage.
