 ARTICLE 2 
 CONTRACTOR’S WORK AND OTHER 
 OBLIGATIONS 
 2.1 Commencement of the Work. 
 2.1.1 Phase 1 Activities. 
 (a) This Agreement shall be effective with respect to the Phase 1 Work on the earlier of the
Effective Date or on the date that a Limited Notice To Proceed (“LNTP”) is issued for the Phase 1 Work, to the extent Phase 1 Work is specifically released in such LNTP. As soon as practical but in no event later than 5 Business Days
following the Effective Date, Owner shall deliver to Contractor a Notice in the form of Appendix I-1 (the “Phase 1 Notice to Proceed”) which will authorize Contractor to commence full performance of the Phase 1 Work on the
Business Day following delivery of such Notice (the “Phase 1 Commencement Date”). On or before the Phase 1 Commencement Date the Parties shall have agreed to the provisions of the Appendices attached hereto with respect to all of
the Phase 1 Work and such matters relating to the Phase 2 Work as shall be included in the Appendices as of the Effective Date. On or before the Phase 1 Commencement Date, Contractor shall provide to Owner evidence of insurance required to be
obtained by Contractor for Phase 1 Work in accordance with Appendix Q, and Owner shall provide the same to Contractor, in each case, if not previously provided. On or before the Phase 1 Commencement Date Owner shall provide the executed
Owner Guaranty to Contractor and Contractor shall provide the executed Contractor Guaranty to Owner. As noted in Section 5.1.2 within eighteen (18) business days after either a LNTP is given to Contractor or the Phase 1 Commencement Date
which ever is earlier, (said 18 day period is the “Review and Transition Period”), Contractor will evaluate whether the Phase I Not-To-Exceed Cost * and/or Phase 1 Maximum Guaranteed Price * needs to be adjusted. Such
evaluation: (a) shall take into account a review of the initial engineering drawings and specifications provided by Owner to Contractor and market-based valuations of reimbursables and other costs necessary to complete the Phase 1 Work, and
(b) shall be open to review by Owner. Upon completion of the Review and Transition Period, Owner shall within five (5) business days confirm in writing to Contractor whether it is authorized to and shall, from and after the confirmation,
proceed with the performance of the Phase 1 Work. As set forth more fully in 5.1.2 under no circumstances shall Contractor perform any Phase 1 Work the cost of which will exceed the Phase 1 Not-To-Exceed Cost, unless after Notice to Owner and
authorization by Owner thereafter to proceed with such Work in excess of the Phase 1 Not to Exceed Cost. In no event, however, shall the cost of the Phase 1 Work to Owner exceed the Phase 1 Maximum Guaranteed Price *. Should Owner not
authorize Phase 1 Work to exceed the Not To Exceed Price, Contractor shall provide such Work as is completed for not more than the Phase 1 Not To Exceed Price, and Owner understands that Contractor does not guarantee that such work shall complete
the Phase 1 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 20 of 133

 
Work. The schedule for performance for the Phase 1 Work is set forth in Appendix A and Appendix B. Subject to this
Section 2.1.1, in no event will the cumulative payment liability of Owner to Contractor in respect of the Phase 1 Work exceed the Phase 1 Maximum Guaranteed Price. In no event will Owner be liable for or responsible for any termination
payment, cancellation fee or other costs incurred by Contractor prior to the Phase 2 Commencement Date for any Work Contractor performs other than the Phase 1 Work unless (x) agreed to by the Parties in a Change Order, (y) if assumed by
Owner pursuant to the provisions of Section 13.4 in connection with a termination of this Agreement, or (z) Owner suspends performance of the Work (or is deemed to have suspended performance of the Work) and then only with respect
to the cost of such suspension as determined under this Agreement or expands the scope of the Phase 1 Work pursuant to a Change Order. The Phase 1 Work is part of the Work for all purposes of this Agreement, including the right to suspend Work for
convenience pursuant to Section 4.4 and the Change provisions of Article 10. It is expressly understood and agreed, however, that if during Phase 1 Owner shall ask Contractor to perform work outside the scope of the Phase 1
Work specified herein such Work shall be performed under the Change Order provisions hereof and is expressly excluded from the Phase 1 Not To Exceed Price and the Phase 1 Maximum Guaranteed Price. For instance, Owner shall be entitled to add the
construction activities at the Project Site to the Phase 1 Work pursuant to a Change Order (other than general mobilization at the Project Site which is included in the Phase 1 Scope of Work) and such work is not subject to the Not to Exceed price
or Guaranteed Maximum Price. 
 (b) Owner and Contractor shall in good faith negotiate the open terms and conditions relating to the Phase 2
Work in an effort to reach agreement with respect thereto (other than the Phase 2 Price Fixed Component) by * and agreement with respect to the Phase 2 Price Fixed Component and the Craft Labor Estimate by *. In the event the Owner and
Contractor have failed to reach agreement as to all aspects of the Phase 2 Contract, including without limitation, scope, terms, price, labor estimate etc; by * then the Owner may commence negotiations with any other Person to perform the
Phase 2 Work notwithstanding the continued good faith efforts of the Parties to reach agreement. Under no circumstances shall either the inability of the Parties to reach agreement with respect to such terms and conditions for Phase 2 Work or
Owner’s commencement of negotiations with another Person be construed as (i) either a Contractor or Owner Event of Default or a default under or breach of this Agreement, or (ii) a Dispute subject to resolution under Article 17
of this Agreement. 
 2.1.2 Phase 2 Notice to Proceed. Upon satisfaction of the requirements of
Section 2.1.3, Owner is entitled to deliver to Contractor a Notice in form of Appendix I-1 (the “Phase 2 Notice to Proceed”), which will authorize Contractor to commence full performance of the Phase 2 Work
on the Business Day following delivery of such Notice (the “Phase 2 Commencement Date”). Owner shall use reasonable efforts to deliver a Notice to Contractor that it intends to deliver the Phase 2 Notice to 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 21 of 133

 
Proceed at least 10 days prior to delivering the Phase 2 Notice to Proceed (the “Phase 2 Advance Notice”). If the Phase 2 Notice to Proceed
has not been delivered to Contractor by * then the Phase 2 Price Fixed Component and Project Schedule will be equitably adjusted until the Phase 2 Notice to Proceed is delivered. If the Phase 2 Commencement Date has not occurred by *
then either Owner or Contractor may terminate this Agreement upon 30 days’ prior Notice to the other Party, and the termination will be effected as described in Section 13.1, without any other liability to either Party as a result
of such termination unless the Phase 2 Notice to Proceed is delivered within such 30 day period.

appropriate to the stage of construction, fabrication or shipment on or off the Project Site as necessary to ensure that such Work is proceeding in accordance with this Agreement and the Project Schedule. All third party inspections, tests or
approvals shall be performed by qualified organizations acceptable to Contractor and Owner. If Applicable Legal Requirements require any Work to specifically be inspected, tested or approved, Contractor shall assume full responsibility therefor and
furnish to Owner the required certificates of inspection, testing or approval. Not later than 30 days after the Phase 2 Notice to Proceed is delivered to Contractor, Contractor will supply to Owner a quality surveillance plan for Specially
Manufactured Equipment during Phase 2. Each monthly progress report delivered by Contractor shall specify the date, time and location of factory tests, inspections and witness points of which Contractor is then aware of and intends to witness with
respect to Equipment and Materials or other work to be provided or performed by its Subcontractors and/or Owner Suppliers in the month following the month in which each such progress report is delivered to Owner. If and when Contractor obtains new
information about such factory tests, inspections or witness points or other factory tests, inspections or witness points that was not available to it when the monthly progress report was delivered, it will promptly advise Owner and update such
information as necessary to allow Owner and the Owner Engineer a reasonable opportunity to attend such event. Contractor shall give reasonable notice of changes to such dates, times and locations to allow Owner and the Owner Engineer to make
arrangements to attend, it being understood that tests, inspections or witness points to be performed outside the United States will require additional notice. Owner and its invitees (including representatives of Owner and the Engineers) shall have
the right, but not the obligation, to attend any inspections, tests or approvals of such Equipment or Materials. In no event shall Contractor’s obligation to provide notice regarding certain tests, inspections or approvals or Owner’s and
its designees’ right to attend tests, inspections or approvals, limit, delay, or modify Contractor’s obligation to perform all tests, inspections or obtain approvals required by this Agreement. Successful completion of factory or other
off-Project Site tests is a precondition to shipment of such Equipment or Materials to the Project Site or other Contractor storage facility; provided, however, Contractor may authorize such shipment if, prior to shipment, Contractor
presents a plan consistent with Professional Standards to Owner to rectify the reasons for such failure. Contractor shall thereafter implement such plan and re-perform and demonstrate that such test has been passed. Should Contractor fail to give
proper notice under this Section 2.2.7, at Owner’s option, Contractor shall re-perform or re-inspect any such test or inspection as to which Contractor failed to give proper notice if Owner has reviewed the test results (which are
to be provided to Owner within 7 days of such failure or as soon thereafter as test results are available

to Contractor) and gives notice to Contractor questioning the validity thereof. Attendance by Owner at any such test or inspection despite the lack of proper
notice will waive Owner’s right to cause Contractor to so re-test or re-inspect. Owner shall require that its Personnel conform to all safety and security requirements that may apply to the location where the inspection shall be performed.

 2.2.8 Labor and Personnel. 
 2.2.8.1 Qualified Personnel. Except as set forth in Section 3.5 with respect to operations and maintenance Personnel,
Contractor shall provide competent and suitable qualified Personnel to perform the Work, and Contractor shall be solely responsible for all labor and Personnel required in connection with the Work, including: (a) professional engineers licensed
to perform engineering services in accordance with Applicable Legal Requirements and qualified to perform the type of engineering services required by Contractor hereunder, and (b) the Contractor’s Construction Manager who has the
experience and authority to supervise and manage the Work on behalf of Contractor. Contractor’s staff shall include the key personnel set forth in Appendix F, who shall be dedicated to the performance of the Work (the “Key
Personnel”). Contractor shall in good faith consult with Owner regarding the removal or replacement of any Key Personnel prior to such action. Without Owner’s prior approval, Contractor shall neither reassign Key Personnel to any other
project nor give Key Personnel tasks related to any matter other than the Work, except to the extent that such reassignment or other tasks (a) could not reasonably prevent, delay or hinder the performance of the Work by Contractor in accordance
with this Agreement or (b) is necessitated by serious personal reasons (e.g., death, retirement, or personal or family illness). If at any time during the performance of the Work, any of Contractor’s or its Subcontractors’ Personnel
becomes reasonably unacceptable to Owner, then, upon notice from Owner setting forth its objections to the performance of such individual, Contractor and Owner shall discuss such personnel issues and attempt to resolve any problem involving such
personnel. If the attempt to resolve such problem is not successful and the employee is unfit or unqualified in the reasonable judgment of Owner, Contractor shall replace as soon as possible any such individual (other than Contractor’s
Construction Manager and senior field superintendents, who shall be replaced only if grossly negligent in the supervision of the Work), in each case, consistent with a diligent effort to find a suitable replacement and shall in good faith consult
with Owner regarding such replacement. If at any time during the performance of the Work any of the Key Personnel should no longer be available to perform services in connection with the Work, then Contractor shall replace such individual with a
replacement reasonably satisfactory to Owner. The replacement or renewal of any such personnel will not entitle Contractor to a Change Order.

comments shall be delivered from Owner to Contractor for its review and comment within 20 days of its receipt by Owner. Contractor shall give due consideration to Owner’s comments and issue a revised plan within 30 days after receiving
Owner’s comments (the “Labor Plan”). The Labor Plan will be updated and approved by Owner prior to the Phase 2 Commencement Date and shall be consistent with the assumptions made during development of the Phase 2 Price
Reimbursable Component. During the performance of the Work, either Party will be entitled to recommend amendments to the Labor Plan. This Section 2.2.8.2 is not intended to limit the right of Contractor to a Change Order with respect to
labor-related matters to the extent Contractor is otherwise entitled to relief therefor under this Agreement. 
 2.2.9
Certain Taxes. 
 2.2.9.1 Sales Taxes. Contractor shall be responsible for the administration and timely
payment, with reimbursement therefor as provided in this Agreement, of all (a) sales and use taxes that are properly payable (“Sales Taxes”) in connection with or arising from the Work, and (b) value added, excise taxes
and import duties that are properly payable by Contractor or any Subcontractor in performance of the Work. All other Taxes (except to the extent similar to those set forth in Section 2.2.9.2) imposed by non-U.S. Governmental Authorities,
duties and fees of any kind, in each case that are properly payable in connection with or arising from the performance of the Work will be reimbursed by Owner to contractor as part of the Time and Materials Costs during Phase 1 and during Phase 2.
In circumstances where a Sales Tax is imposed for purchases that are not exempt from Sales Tax pursuant to exemption programs identified by Owner to Contractor or for which an exemption is not applicable, Contractor shall be reimbursed in accordance
with Section 3.4 for its payment of all such Sales Taxes; provided, however, if Sales Taxes (for which an exemption would have otherwise applied) are paid because of the Contractor’s failure to furnish or cause to be furnished a
properly completed Sales Tax certificate as provided in Appendix L or any other failure by Contractor to perform its obligations hereunder, then Contractor shall reimburse Owner, at Contractor’s expense for the reasonable costs
incurred by Owner in 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 30 of 133

 
seeking a refund of such Sales Taxes from appropriate authorities. Contractor shall furnish to the appropriate taxing authorities all required information
and reports in connection with all Contractor Taxes and Sales Taxes as described in Appendix L or otherwise reasonably requested in a notice from Owner to Contractor. Contractor shall provide assistance as reasonably requested by Owner
or its tax consultant(s), in confirming eligibility and qualification for exemptions from Sales Taxes (and any other exemptions) to the relevant Governmental Authorities. From time to time and within 30 days of a request therefor, Contractor shall
provide Owner with information regarding quantities, descriptions, and costs of property installed at the Project reasonably requested by Owner in connection with the preparation of Owner’s tax returns, satisfying regulatory requirements or as
otherwise required in connection with Financing or with obtaining exemption from, or rebate of, Sales Tax. Contractor agrees to participate in any Sales Tax exemptions or rebate programs identified by Owner, to complete and deliver the applicable
documentation to obtain tax-exemption for purchases of Equipment and Materials, and to pass any Sales Tax savings or rebates through to Owner. Owner hereby notifies Contractor that all Equipment, Materials and Consumables to be utilized within the

enterprise zone designated in Appendix L on Notice to Contractor. 
 2.2.9.2 Contractor Taxes. Contractor
shall be liable, without reimbursement by Owner hereunder, for (a) all foreign and U.S. federal, state, local, and other taxes, which may be assessed on Contractor’s net income or gross receipts (except taxes on gross receipts that are
deemed to be Sales Taxes), and (b) all corporate engineering, contractor, or business license costs and franchise fees required for Contractor to conduct business in the State of Louisiana, (collectively, the “Contractor
Taxes”). Neither the Phase 2 Price Fixed Component nor the Total Installed Cost will include Sales Taxes or Contractor Taxes. 
 2.2.9.3 Applications for various federal, State of Louisiana, county and other local incentive programs and inducements related to the construction of the Project have been (or will be) submitted by, or on behalf of,
Owner. At the request of Owner, Contractor will support Owner and its consultants in order to fully utilize the incentives offered. Participation in this effort, when requested by Owner, will include assistance with information requests to third
Persons for filings related to the programs, assistance with tracking specific costs related to the incentive programs, providing

		 		 	Page 31 of 133

 
Contractor and Subcontractor employee headcounts and (to the extent reasonably available) payroll information, and other reasonable assistance as may be
requested in a timely manner; provided, however, such assistance shall not require Contractor to (a) engage in lobbying or other efforts to obtain favorable legislation, (b) require the release of confidential personnel data or
(c) engage in litigation, administrative proceedings, or other efforts to obtain favorable judicial outcomes. Contractor shall cooperate and provide testimony, documentation and other relevant information in connection with Disputes with
respect to Taxes assessed against, payable by or for which Owner is responsible, to the extent relating to the Work performed under this Agreement. 
 2.2.10 Permitting. Contractor shall obtain, pay for, and maintain in effect, all permits and governmental approvals that are necessary for Contractor to perform the Work, excepting only Owner Permits
(“Contractor Permits”). Owner shall obtain the Owner Permits, and Contractor shall perform the Work so as to comply with and, as applicable, to maintain Owner Permits. Each Party shall provide the Party responsible for a Permit with
information in its possession or reasonably available to it, as is reasonably required by the responsible Party in order to obtain and keep such Permit in full force and effect. Costs incurred by Contractor to obtain and/or maintain licenses,
certification and other permissions of Governmental Authorities to conduct its business in the State of Louisiana will not be part of the Time and Materials Costs. 
 2.2.11 Personnel Training. In accordance with the Project Schedule, during Phase 2 Contractor shall provide the facilities,
material, supplies, personnel and other items required to train the operations and maintenance personnel to be provided by Owner in the proper and safe operation and maintenance of the Project, as further described in Appendix A.

 2.2.12 Safety Precautions. Until the Substantial Completion Date, Contractor shall be solely responsible for
developing, implementing, and administering job site safety requirements. Owner shall have no responsibility therefor, except as otherwise expressly provided in this Agreement. Beginning on the Substantial Completion Date, Owner shall assume
responsibility for developing, implementing, and administering site safety. Each Party, to include Financing Parties and the invitees of any Party shall abide by the safety requirements of the Party that has responsibility for administering such
requirements. Contractor shall assign a full-time safety and health manager who will be responsible (until the Substantial Completion Date) for introducing, administering and monitoring procedures to promote safe working conditions at the Project
Site, in compliance with Applicable Legal Requirements. In addition to reporting to the Contractor’s Construction Manager, such safety and health manager shall have direct reporting responsibility to Contractor’s home office management.
Contractor shall notify Owner orally of all potential lost-time accidents at the Project Site suffered by individuals at the Project Site as soon as possible but no later than 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 32 of 133

 
any deadline to report such matter to a Governmental Authority. Contractor shall furnish Owner a written report describing each such accident, and the
injuries incurred, within 2 Business Days after occurrence of the accident, which shall include any written reports thereof required to be submitted to any Governmental Authority. Such report must also contain the cause of the occurrence (if known)
and the actions taken or to be taken to avoid repetition. Contractor shall promptly give Notice to Owner of any hazardous conditions at the Project Site immediately after it becomes aware of such conditions. Contractor shall also comply with
Applicable Legal Requirements and the requirements of Appendix A with respect to the Phase 2 Work bearing on the safety of individuals or property (on and off the Project Site) or their protection from damage, injury or loss. As part of
the Phase 1 Work, but, in all cases, prior to the performance of any Work on the Project Site by Contractor, Contractor shall prepare and provide Owner with an initial draft of the Project Safety Manual. Such draft Project Safety Manual shall
include (a) express prohibitions on the presence of alcohol, controlled substances, firearms (except, with the prior consent of Owner, for trained security personnel), explosives (except as necessitated for performance of the Work), or other

thereby, (ii) all Materials and Equipment in storage at the Project Site, or under the care, custody or control of Contractor or any Subcontractor, and (iii) other property at or immediately surrounding the Project Site. In emergencies
affecting the safety or protection of Persons or the Work or property at the Project Site, Contractor, without special instruction or authorization from Owner, shall reasonably act to prevent damage, injury, or loss. Whenever Contractor has failed
to take sufficient precautions for the safety of the public or the protection of the Project or of structures or property at the Project Site, creating, in the opinion of Owner, an emergency requiring immediate action, then Owner may cause such
sufficient precautions to be taken or provide such protection. Owner shall give Contractor Notice as soon as practicable under the circumstances regarding the action it intends to take, or if circumstances do not reasonably permit prior Notice, the
action it has taken; provided, however, the failure by Owner 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 33 of 133

 
to include all actions it takes in such Notice shall not preclude Owner from taking all necessary action, nor relieve Contractor of any of its obligations
hereunder. The taking or providing of any such precautions or protection by Owner or its agents or representative will not relieve Contractor of its obligations under this Agreement and Applicable Legal Requirements. The cost incurred by or on
behalf of Owner to take such precautions or protection by or on behalf of Owner shall be added to the Total Installed Cost. 
 2.2.13 Hazardous Substances. 
 2.2.13.1 Prevention of Releases; Notice. Contractor shall take
reasonable measures necessary to prevent the Release or threatened Release of any Hazardous Substances at the Project Site. Contractor shall immediately notify Owner of: (a) any Release or threatened Release of Hazardous Substances that occur

and incremental Remediation associated with a Release or threatened Release of any non-Contractor Hazardous Substance after it has been discovered by or specifically identified to Contractor or its Subcontractors or their Personnel, to the extent
that such Release or threatened Release was caused by Contractor, its Subcontractors or their respective Personnel, provided, however, that Contractor liability under this subsection (b) shall not exceed *. Contractor
shall not be responsible for paying any portion of a fine that is imposed upon Owner as a result of a prior violation for which Contractor or its Subcontractors or their respective Personnel were not responsible. 
 (c) If Contractor should fail or refuse to commence and diligently pursue Remediation required of it in accordance with this
Section 2.2.13.2, then Owner may, at its discretion and after 48 hours’ Notice to Contractor, perform such Remediation as it deems necessary or adequate. All reasonable costs and expenses of such Remediation shall be billed to the
account of Contractor, who shall promptly reimburse such amounts to Owner, which amount shall not be included as part of the Total Installed Cost. 
 (d) To the fullest extent permitted by Applicable Legal Requirements, Contractor agrees to and shall release, defend, indemnify and hold harmless Owner, the Engineers and the Financing Parties and their respective
directors, commissioners, members, officers, employees, agents, and Affiliates from and against all Claims (except to the extent Claims arise from the negligence or intentional misconduct of such indemnified Persons) to the extent arising out of
(i) failure by Contractor to perform its obligations under this Section 2.2.13 with respect to Contractor Hazardous Substances and/or (ii) the incremental damage, liability or Remediation for which Contractor is responsible
under this Section 2.2.13.2 with respect to non-Contractor Hazardous Substances, whether through suits or causes of action in a court of law or claim, complaints or penalties arising out of a violation or alleged violation of Applicable
Legal Requirements.

Contractor further agrees that it shall, upon request, provide the aforementioned Persons with such information during the performance of this Agreement in a timely fashion and subject only to the confidentiality restrictions provided in
Article 18. Nothing herein implies conveyance of any Intellectual Property of third parties other than Contractor vendors to the extent set forth in purchase agreements. 
 2.5.3.3 Inventions. All inventions directly related to Owner processes or operations arising from the Work shall be the property of
the Owner. In the event Contractor obtains legal entitlements to such inventions, the provisions of this paragraph shall require Contractor to transfer such entitlement to Owner prior to the Final Completion Date, without cost to Owner. Contractor
grants to Owner an irrevocable, royalty-free, non-exclusive and perpetual license and right to practice, perform, make, copy, create derivative works of, import and otherwise use any and all inventions reasonably arising from the Work that are
necessary for the construction, operation, maintenance, improvement, replacement, expansion or repair of the Project, all without additional cost to Owner or any Owner in connection with the Project.

Notice to Owner and safeguard such articles or items. 
 2.5.6 Title Warranty. Contractor warrants that upon passage of
title to the Work in accordance with Section 2.5.1, Owner will have good and indefeasible title to such Work not subject to any Lien, privilege, security interest or other defect in title. Without limiting Contractor’s obligation
under Section 12.2, in the event of any non-conformity with this warranty, Contractor, at its own expense upon written Notice of such failure, shall cure such defect. The provisions of this Section 2.5.6 will survive the
execution or earlier termination of this Agreement. 
 2.6 Subsurface Conditions. In accordance with Section 2.2.1,
during Phase 1 Contractor shall inspect the Project Site, conduct such tests and make such investigations that are consistent with Professional Standards, review the information provided to it by Owner relating to surface and subsurface conditions,

 2.14.3 Due Consideration. Owner shall review Submittals within the time-period specified in Appendix A, but review by
or on behalf of Owner shall be only for conformance with the design concept of the Project and for compliance with this Agreement and shall not extend to means, methods, techniques, sequences, or procedures of construction (except where a specific
means, method, technique, sequence, or procedure of construction is indicated in or required by this Agreement). The review of a separate item as such shall not indicate approval of the item or the component in which the item functions. Contractor
shall give due consideration to Owner’s comments and make reasonable changes or corrections required by Owner, and resubmit as required to reflect such Owner changes or corrections. Upon re-submission, Contractor shall direct specific attention
in writing to revisions to Submittals. Owner will not have any responsibility or liability for the accuracy or completeness of any Submittal, or for any defect, deficiency thereof or for any failure of such Submittal to comply with the requirements
of this Agreement, notwithstanding any review or comment on its part.

completion of the Work in accordance with the Project Schedule. Costs incurred by Contractor under this Section for legal defense in matters not involving its own Personnel or its Subcontractor’s Personnel will be reimbursable by Owner if Owner
directs Contractor to undertake such legal action. 
 2.18 Discipline and Protection. Contractor shall enforce strict discipline and
good order among its employees, its Subcontractors’ employees, Owner Supplier employees and any other Persons carrying out portions of the Work on the Project Site and provide for the protection and maintenance of the Work and Owner Equipment
and Materials on the Project Site and of all Persons and property related thereto. Contractor shall at all times take reasonable and appropriate actions to prevent any unlawful or disorderly conduct by or amongst its employees and those employees of
Subcontractors and Owner Suppliers on the Project Site. Contractor shall not permit the employment, by it or its Subcontractors, of unfit Persons or Persons not skilled in tasks assigned to them. Owner shall do the same in respect of its Separate

 ARTICLE 4 
 OWNER’S RIGHT TO INSPECT, STOP AND 
 RE-PERFORM WORK 
 4.1 Inspection. Owner and its designees will have the right to have access to and inspect the Work, including Equipment and Materials, and to be
present at all tests and inspections at any stage of completion on the Project Site. The participation in, or observation of, any such inspections or testing by Owner and its designees (or any failure by Owner or its designees to participate in or
observe such inspections and testing) will not be deemed to constitute a waiver of any of Contractor’s obligations under this Agreement or be construed as an approval or acceptance of the Work. So long as Contractor provides reasonable advance
notice to Owner of a test or inspection (such notice may be in the form of the identification of such test or inspection in the Project Schedule, Monthly Progress Report or other written Submittal to Owner but must be at least 5 Business Days prior
to such test or inspection), then the failure of Owner or its designees to be present at such test or inspection will not invalidate or otherwise adversely affect the conduct or results of such test or inspection. Owner or its designees exercising
rights pursuant to this Section 4.1 shall not unreasonably interfere with Contractor’s performance of its obligations hereunder. 
 4.2 Right to Reject and Re-Performance. Prior to the Warranty Period, if the Work is not in conformance with the requirements of this Agreement (“Defective Work”), then Owner may give
Contractor Notice of the Defective Work. If Owner provides Notice to Contractor that Owner requires a plan of correction for Defective Work, then Contractor shall, within 7 Business Days after Owner’s Notice thereof, submit a plan of correction
of the Defective Work to Owner for review and Contractor shall include in the plan of correction any reasonable comments to such plan proposed by Owner. Contractor shall provide Notice to Owner of any modifications or supplements to the plan of
correction reasonably implemented by Contractor. For purposes of this Agreement, “Defect,” “Defects” or “Defective” describes Work that is not in conformance with the requirements of this Agreement.

 4.3 Defects in Owner Suppliers’ Scope. Prior to the Warranty Period, if either Party obtains knowledge of any defect or
deficiency in any Owner Suppliers’ Scope, such Party shall give Notice thereof to the other Party, and Owner shall thereafter enforce the provisions of the applicable Owner Contract and secure from the applicable Owner Supplier a plan of
correction for such defect or deficiency. Upon Owner’s request, Contractor shall cooperate with Owner in such enforcement. Any legal expenses so incurred by Contractor to cooperate with enforcement of the Owner Contract shall be a reimbursable
expense.

		 		 	Page 58 of 133

 4.4 Right to Suspend Work for Convenience. Owner may, at any time and from time to time, by a
Notice, suspend (and later reinstate) all or any portion of the Work. Upon receipt of such Notice, Contractor shall immediately suspend its performance of such Work consistent with a safe and orderly shut-down of such Work. Either Party may
terminate this Agreement, with such termination being handled under Section 13.1 hereof, if (a) in the case of a suspension of all or substantially all of the Work by Owner for convenience after the Phase 2 Commencement Date, the
suspension of Work exceeds 270 days in the aggregate, or (b) in the case of a suspension resulting from the occurrence of a Change of Law or event of Force Majeure occurring after the Phase 2 Commencement Date, a single suspension of all or
substantially all of the Work exceeds 360 days. In the case of either (a) or (b) above, Contractor may reassign Key Personnel engaged in Work at the Project Site if any such suspension of the Work exceeds 75 consecutive days. If Contractor
reassigns Key Personnel in accordance with this Section 4.4, it shall use reasonable efforts to reassemble the original Key Personnel at such time as the suspension of the Work is lifted. If the project is suspended by Owner, Contractor
shall be paid for all completed work prior to such suspension as follows: 
 (a) Cost reimbursable work shall be compensated for all such
work performed up to date of suspension. For fixed price component, all milestones achieved prior to suspension shall be paid and, in the event that a suspension lasts for more than 30 consecutive days, Contractor shall be entitled to invoice Owner
for an equitable proportion of the applicable Milestone Payment Schedule for partially completed Milestones. 
 (b) All cost resulting from
the suspension of Work including on-going costs and reasonable cost of work required to secure and protect partially completed work but excluding time value of money, lost opportunity costs and the like, shall be paid via change order process on a
time and material basis or lump sum if mutually agreed, provided however, to the extent reasonably possible, Contractor shall provide advanced written notice of such anticipated cost so Owner has the opportunity to avoid or mitigate said costs.
Contractor shall use reasonable efforts to minimize such extra costs arising from suspension, including consultation with Owner as to potential reassignment of Contractor’s personnel and/or suspension of the Work of Subcontractors. 

4.5 Uncovering Work. Without limiting Owner’s right to inspect the Work at any time on the Project Site, at each weekly construction
meeting at the Project Site occurring during Phase 2, Contractor shall provide to Owner a copy of Contractor’s 3 week look-ahead schedule for Work to be performed on the Project Site. Owner shall promptly advise Contractor in writing of those
items of Work on such look-ahead schedule that it specifically wants to witness or inspect. For those items of Work that Owner advises Contractor that it wants to witness or inspect, Contractor shall keep Owner reasonably apprised of changes to the
time and location of 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 59 of 133

 
the performance of such events. If Contractor performs any such item of Work at a time as to which Owner did not have Notice in accordance herewith, then,
upon Owner’s written request, given within 7 days of the date on which Owner was advised that such Work would be performed, Contractor shall expose, uncover or otherwise test such Work as Owner may reasonably require. If Owner fails to witness
or inspect Work which it had requested the opportunity to witness or inspect, Contractor shall be entitled to proceed with such Work and Owner shall not be entitled to enforce its rights under this Section 4.5, except upon issuance of a
Change Order to Contractor in accordance with Article 10. With respect to any other Work that is covered by Contractor, Contractor, at Owner’s written request, shall uncover, expose, or otherwise make available for observation,
inspection, or testing as Owner may require. If Work is Defective, Contractor shall (a) not be entitled to a Change Order on account thereof, including any cost or delay associated therewith, and (b) prepare a Recovery Plan if there is a
delay in the Project Schedule. If, however, such Work is not Defective, Owner shall issue Contractor a Change Order in accordance with Article 10 for the associated impact, as demonstrated by Contractor in a Change Order Request.

 4.6 Right to Stop Work for Cause. Owner, by a Notice, may order Contractor to stop performance of that portion of the Work that
reasonably appears to Owner to cause or threaten to cause an imminent danger to life or damage to property. If it is reasonably determined by Owner that such activities of Contractor or Contractor’s Personnel caused or threatened to cause
imminent danger to life or damage to property, Contractor shall not be entitled to a Change Order for the associated impact. Owner’s right to stop Work under this Section 4.6 shall be without prejudice to any other right or remedy
Owner may have under this Agreement. Once the cause of the stop work order has been resolved by Contractor, Owner shall promptly direct Contractor to resume performance of the Work that had been stopped. In the event that any stop work order Notice
provided hereunder is subsequently determined to not have been properly issued in accordance with the provisions of this Section 4.6, Owner shall issue a Change Order to Contractor in accordance with Article 10, to reflect
any cost or schedule impact, as demonstrated by Contractor in a Change Order request.

 ARTICLE 5 
 COMPENSATION AND PAYMENT 
 5.1 Phase 1 Compensation. As full and complete compensation for the
timely performance of the Phase 1 Work, Owner shall pay, or cause to be paid to Contractor, the Time and Materials Costs for the Phase 1 Work as more particularly described in Appendix K (which amount shall be subject to Retainage as
described below). All Time and Material Costs shall be charged on an open book basis so that Owner shall have access at all reasonable times to the backup documentation. Subject to estimate confirmation procedure set forth in Section 5.1.2
below, the “Phase 1 Not-to-Exceed Cost” is * and Contractor agrees that it will not exceed this amount without Owner’s written permission obtained after first advising Owner that the Phase 1 Not-to-Exceed Cost is
likely to be exceeded and the reason therefore. Owner shall have the right to adjust scope and otherwise revise the Phase 1 Work (including deliverables) in order to keep the cost of the Phase 1 Work within or as close to the Phase 1 Not-to-Exceed
Cost as possible, and Contactor shall reasonably cooperate in efforts to reduce the cost of Phase 1 Work so as to complete the Work in the most cost effective manner possible and avoiding duplication of effort to the extent possible. It is
understood, however, that Contractor does not guarantee that the Phase 1 Work can be completed within the Phase 1 Not-to-Exceed Cost. In no event shall the total Compensation paid for the Phase 1 Work (exclusive of any Change Orders) exceed the
Phase 1 Maximum Guaranteed Price of *, and upon payment to Contractor for the Phase 1 Work of an amount equal to the Phase 1 Maximum Guaranteed Price, Contractor shall complete the remainder of the Phase 1 Work hereunder and provide
all Phase 1 deliverables without further Compensation from Owner. 
 5.1.1 Time and Materials Costs. Time and Materials
Costs shall be paid to Contractor based upon the actual time incurred to perform the Phase 1 Work, the time charges set forth in Appendix K and the actual materials costs incurred by Contractor to perform the Phase 1 Work. As more fully set
forth in the Appendix K, the time charges for labor will be billed at actual rates plus fixed markups. All subcontracts, Materials and expenses otherwise incurred in Phase 1 shall be reimbursed at cost without mark-up or premium/profit. Time and
Materials Costs must be charged by Contractor in accordance with its generally applicable policies and procedures set forth in Appendix K, or in the absence of a specific policy or procedure, be consistent with charging practices customarily
employed by Contractor in the execution of its other power projects. Contractor shall be compensated for all Time and Materials Costs incurred in connection with completion of the Phase 1 Work in accordance with the Project Schedule for the Phase 1
Work. Contractor shall not be compensated for (a) any Time and Materials Costs incurred to make-up a delay in the Phase 1 Project Schedule that is due to fault or error of Contractor or (b) Time and Materials Costs incurred to correct
Phase 1 Defective Work. Time and Materials Costs shall be subject to the criteria and limitations set forth in Appendix K. Time and Materials Costs payments shall be subject to Retainage as provided below.

 5.1.2 Confirmation of Phase 1 Not-to-Exceed Cost and Maximum Guaranteed Price.
Contractor has based its Phase 1 Not-to-Exceed Cost and Phase 1 Maximum Guaranteed Price upon information supplied by Owner to date. Upon execution of this Agreement or on the date that a Limited Notice To Proceed (“LNTP”) is issued for
the Phase 1 Work, Contractor shall have eighteen (18) Business Days (the “Review and Transition Period”) to review all of Owner’s engineering completed to date to satisfy itself with the status of such work and the amount
of Work required to complete Phase 1. Within two (2) Business Days of the end of the Review and Transition Period, Contractor shall confirm in writing that the Phase 1 Not-to-Exceed Cost and the Phase 1 Maximum Guaranteed Price are confirmed
or, if not, advise of Contractor’s new Phase 1 Not-to-Exceed Cost and Phase 1 Maximum Guaranteed Price and the reasons for such changes. Owner shall have five (5) Business Days to either accept or reject any revised Phase 1 Not-to-Exceed
Cost or Phase 1 Maximum Guaranteed Price. If Owner rejects the revised Phase 1 Not-to-Exceed Cost or Phase 1 Maximum Guaranteed Price, Owner shall have the right to terminate this Agreement with no further liability to Contractor; provided, however,
that Owner shall pay Contractor for its Work up to such date of termination, including the Work done to confirm Contractor’s Phase 1 Not-to-Exceed Cost and Phase 1 Maximum Guaranteed Price. If Owner accepts a revised Phase 1 Not-to-Exceed Cost
and/or Phase 1 Maximum Guaranteed Price for Phase, the revised amounts shall replace the amounts set forth above in Section 5.1. 
 5.1.3 Changes in Phase 1 Compensation. Contractor shall not be entitled to any change or adjustment to the rates or methods of calculation of its Time and Materials Costs unless included as part of a Change
Order approved by Owner or mandated as a result of the resolution of a Dispute related thereto in favor of Contractor. It is understood, however, that if the scope of Work requested by Owner in Phase 1 is changed so as to increase the amount of
Phase 1 Work, Contractor cannot assure that Work associated with such expanded scope can be completed within the Phase 1 Maximum Guaranteed Price. Should the Owner request a Change that in Contractor’s judgment expands the Scope of Phase 1
Work, Contractor shall, in addition to complying with the Change Order provisions of this Agreement, promptly notify Owner whether such expanded scope will require an increase in the Phase I Guaranteed Maximum Price. 
 5.1.4 Phase 1 Monthly Payments. Subject to Section 5.4, the Compensation for Phase 1 will be paid to Contractor in
monthly installments upon completion and delivery to Owner of Applications for Payment in accordance with the payment procedures set forth in this Agreement. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 62 of 133

 5.1.5 Phase 1 Applications for Payment. On the first Tuesday after the first
Monday of a calendar month, Contractor shall submit to Owner an Application for Payment filled out and signed by Contractor Each Application for Payment shall describe (i) all Work completed, the associated Time and Materials Costs for such
Work and the sum of all prior payments made by Owner to Contractor through the last day of the prior month, (ii) the amount of Time and Materials Costs owed to Contractor based upon the completed Work, and (c) any amount due for which
payment was withheld from an earlier payment and where the cause for such withholding no longer applies. The aggregate amount of Compensation for Phase 1 Work for which Contractor may submit a monthly Application for Payment will not exceed the
Phase 1 Not-to-Exceed Cost without the prior written approval of Owner, which approval will not be withheld unless the scope of Work for Phase 1 is changed pursuant to a Change Order. The Phase 1 Maximum Guaranteed Price will be adjusted a necessary
in connection with any Change Order. 
 5.1.6 Phase 1 Progress Reports. Each Application for Payment submitted by
Contractor for Phase 1 Work must be supported by documentation (updated schedule, Earned Value System Report, progress curves, Payroll backup) supporting the invoice and indicating the progress accomplished during the invoicing period. A monthly
progress report in accordance with Appendix A for the month preceding the Application for Payment will be delivered to the Owner not later than the second Friday following Contractor period closing date. Such progress report shall also
include a good faith forecast of (i) the estimated Time and Materials Costs that Owner will be liable to pay to Contractor, and (ii) the payments to be required to be made under all of the Owner Contracts, in each case, for the 90 day
period commencing with the month following the month in which the Application for Payment is submitted. It is recognized that forecasts are forward-looking projections and variances from such forecasts shall not affect Owner’s payment
obligations hereunder. 
 5.1.7 Phase 1 Lien Waivers. With each Application for Payment submitted by Contractor for
Phase 1 Work, Contractor shall deliver to Owner and any title company specified by Owner a waiver and release of Liens in the form of Appendix I-11, duly executed and acknowledged by Contractor and those Subcontractors with an aggregate
contract value equal to or exceeding fifty thousand dollars ($50,000.00) in order to assure an effective release of mechanics’ or materialmen’s Liens in respect of the Work performed in the preceding month in accordance with the laws of
the State of Louisiana. In addition, Contractor shall deliver to such title company a duly executed and acknowledged Contractor’s statement satisfying all Applicable Legal Requirements identifying each of the Subcontractors, the value of such
subcontract, the amounts paid to date, and the balance of the amount due or to become due to each, and a statement that all undisputed payments then due and owing have been made to such Subcontractors in accordance with the terms of the applicable
Contractor subcontract as of the date of such statement; provided, that Owner has made all undisputed Compensation payments when due. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 63 of 133

 5.1.8 Other Documentation. Each Application for Payment submitted by Contractor
for Phase 1 Work must be fully completed and also include the following in form and substance reasonably satisfactory to Owner: 
 (a) a duly executed Contractor’s certification stating that it has reviewed all financial information contained in the Application for Payment as true, correct and complete; 
 (b) a copy of all invoices pursuant to which Contractor has paid Sales Taxes for which it seeks reimbursement; 
 (c) information in such detail and with such backup as indicated in Appendix I-2 so as to allow Owner to sign off on the reconciliation
and verification of Time and Materials Costs; 
 (d) such other information as may be reasonably required by Owner.

 5.1.9 Failure to Comply. To the extent Contractor fails to comply with the foregoing requirements with respect to
timely submission of documentation with the Application for Payment, Owner shall, after issuing a Notice to Contractor, be entitled to withhold an equitable portion of the payment due to Contractor up to 25% of the amount of the Application for
Payment unless and until such documentation is provided. 
 5.1.10 Phase 1 Retainage. Contractor agrees that *
of the Time and Materials Costs otherwise payable to Contractor during Phase 1 shall be retained (the “Phase 1 Retainage”) by Owner out of each payment in respect of the Phase 1 Work. Owner shall have the right to apply the
Retainage so withheld to satisfy any payment obligation of Contractor under this Agreement that is not paid when due hereunder. Upon satisfactory completion of the Phase 1 Work, the Phase 1 Retainage withheld during Phase 1 shall be paid to
Contractor with the final Phase 1 payment, other than Phase 1 construction direct Craft Field Labor, construction subcontractors and construction materials required in connection with any Change Order requiring Contractor to begin construction
activities as part of the Phase 1 Work. 
 5.1.11 Phase 1 Compensation Inclusive. The Parties agree that the
Compensation provided for in this Section 5.1 includes all Project cost components required for full and satisfactory completion of the Phase 1 Work other than Phase 1 construction direct Craft Field Labor, construction subcontractors

 5.2 Phase 2 Compensation. The Phase 2 Price shall consist of 2 components: the Phase 2 Price Fixed
Component and the Phase 2 Price Reimbursable Component. The pricing of these two components of the Compensation for the Phase 2 Work shall be developed as follows: 
 5.2.1 Phase 2 Price Fixed Component. During Phase 1, Contractor shall develop a fixed lump sum Phase 2 Price Fixed Component for
the timely performance of the agreed Phase 2 Work (the “Phase 2 Price Fixed Component”). The Phase 2 Price Fixed Component shall address all components of the Work aside from the Craft Labor Cost Component which shall be paid on a
cost reimbursable basis (the “Phase 2 Price Reimbursable Component”) as set forth below. The Phase 2 Price will include contingency on only the Phase 2 Price Fixed Component. The Phase 2 Price Reimbursable Component shall be based
on a detailed estimate to be provided to Owner (the “Phase 2 Price Reimbursable Component Estimate”). The Phase 2 Price Reimbursable Component Estimate will be subject to an open-book review by Owner so that included cost component
factors can be reviewed and the appropriate level of Owner Project contingency can be determined. The Phase 2 Price Fixed Component shall be based on a detailed estimate to be provided to Owner (the “Phase 2 Price Fixed Component
Estimate”). The Phase 2 Price Fixed Component Estimate shall be subject to an open-book review by Owner so that included cost component factors can be reviewed and the appropriate level of Owner Project contingency can be determined. Also,
in order to reduce total cost of the Project and risk, Contractor shall advise Owner during Phase 1 of any and all items that Contractor recommends Owner purchase in advance (e.g., crane rentals). The items to be included in the Phase 2 Price Fixed
Component include, without limitation, the following. 
 5.2.2 Home office services including engineering 

 

	 	•	 	 Field supervision 

  

	 	•	 	 Temporary facilities 

  

	 	•	 	 Field office expenses 

  

	 	•	 	 Construction equipment, including heavy lift cranes (provided Owner reserves cranes in advance as requested by Contractor) 

  

	 	•	 	 Tools and consumables 

  

	 	•	 	 Insurance 

  

	 	•	 	 Miscellaneous expenses 

  

	 	•	 	 Contingency (on fixed components, quantities, and contract risk) 

  

	 	•	 	 Plant Equipment * 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 65 of 133

	 	•	 	 Bulk Materials* 

  

	 	•	 	 Special tools for maintenance and recommended spare parts 

  

	 	•	 	 Contractor Fee/Profit and overhead 

 It is
understood, however, that fixing price on the items with asterisk will be contingent upon Owner timely agreeing to commit funds early to (a) reserve certain scarce equipment (e.g., heavy cranes), (b) fix price on volatile commodities
(alloy steel), (c) fix equipment supplier prices and other similar issues. Any issue affecting ability to fix price shall be promptly brought to Owner’s attention so that Owner can address expeditiously. It is further understood that
development of the cost for special tools and spare parts is largely contingent on subsequent procurements and Owner approval of recommended spare parts lists. As such, Contractor will provide a fixed cost estimate for special tools and spare parts
based on Contractor expertise, industry standards, and total project equipment costs. This fixed cost estimate will be subject to adjustment via change order following Owner approval of Contractors recommended special tools and spare parts list. The
Phase 2 Price Fixed Component shall be developed in accordance with the mutually agreed Phase 1 Project Execution Plan schedule. 
 5.2.3 Phase 2 Price Reimbursable Component. During Phase 1, Contractor shall develop a detailed Phase 2 site “bottom up” labor estimate, itemized by installed item of Equipment that includes for each item: (a) the
expected man-hours, by classification within each Craft Labor Category to install such Equipment, and (b) the average apprentice and journeyman rate for each Craft Labor Category (the “Craft Labor Cost Estimate”). As used above
“item” includes each and every individual engineered product, all non engineered procured items and each individual bulk material item used to install and interconnect each engineered and non-engineered item of Equipment, inclusive of all
support utility materials. All labor other than on-site Craft Labor shall be part of the Phase 2 Price Fixed Component. Contractor shall provide Owner at the same time it provides the Phase 2 Price Fixed Component, the Craft Labor Estimate which
shall be the basis for determining the estimated total Phase 2 Craft Labor Hours and the Craft Labor hour target amount for the Phase 2 Work (the “Craft Labor Hour Target”). The wage rates for the Craft Labor Cost Estimate shall be
developed by Contractor through a labor survey in the relevant region, and such survey shall be provided to Owner upon request so that Owner and Contractor can collectively agree on a wage rate strategy for attracting the necessary Craft Labor. Base
Craft Labor rates and per diem will be agreed upon by the Parties as a precondition to the occurrence of the Phase 2 Commencement Date. As Work on the Project progresses, if Contractor demonstrates to Owner that the stipulated Craft Labor rates or
per diem need to be increased to attract and retain qualified Craft Labor based upon market conditions or can be decreased without reducing productivity or availability of labor, the new rates will be implemented and associated cost will be
reimbursable, subject to the Craft Labor productivity reconciliation pursuant to Section 5.2.6.

		 		 	Page 66 of 133

 5.2.4 Payment of Phase 2 Price Fixed Component. The Phase 2 Price Fixed Component
shall be paid to Contractor in accordance with the Milestone Payment Schedule set forth in Appendix G. The Milestones and Milestone Payment Schedule shall be developed and agreed during Phase 1. The objective of the Milestone Payment Schedule
shall be to assure that payments made by Owner to Contractor in respect of the Phase 2 Price Fixed Component reflect the value of the Work completed to the Owner and to maintain Contractor in a cash neutral position (excluding Retainage) so that
Contractor is not financing the Work. The Milestone Payment Schedule for Phase 2 agreed upon by the Parties as part of the Phase 1 Work shall thereafter be included in Appendix G. 
 5.2.5 Payment of the Phase 2 Price Reimbursable Component. Contractor shall invoice biweekly for field Craft Labor based upon Work
performed the previous biweekly period, and Owner shall pay correct and properly documented invoices within 15 days of receipt. Such invoices shall include, at a minimum, certified payroll records (subject to audit) verifying pay rates. 

5.2.6 Price and other Agreement Adjustments due to Change Orders. All adjustments to the Phase 2 Price Fixed Component due to
Change Orders shall be calculated as follows: 
 a) Schedule Changes. 
 i. The Phase 2 Price Fixed Component will be equitably adjusted for schedule delays to the extent caused by Owner. Contractor shall
provide documentation of costs incurred for schedule extension or schedule acceleration. 
 b) Scope Changes 
 Changes initiated by Owner in the Phase 2 Work after the Phase 2 Notice to Proceed shall generally be estimated and priced in the same manner as the original Phase 2
Price Fixed Component was developed consistent with lump sum contracting practices, and shall be handled as follows for the specified situation:. 
 i. Unit Priced Work Where the Phase 2 Price Fixed Component was based upon unit pricing such pricing shall be used for scope adjustments, subject to equitable market adjustments applicable to such pricing for
the quantity of unit purchased.

		 		 	Page 67 of 133

 ii. Engineering Scope: For Changes in the Phase 2 Work after the Phase 2 Notice
to Proceed (other than as provided in (i) above) that increase the engineering scope, Contractor shall provide Owner with a proposed fixed price developed in the same manner as the original Phase 2 Price Fixed Component was developed consistent
with lump sum contracting practices but if the Parties cannot agree on the proposed lump sum, the cost of the Change shall be equitably adjusted based upon stipulated hourly billable rates to be appended hereto as part of Appendix K and
Contractor’s documented hours worked. 
 iii. Equipment Materials and Subcontracts: For Changes in the Phase 2
Work after the Phase 2 Notice to Proceed (other than as provided in (i) above) that increase the amount of Equipment Materials or Subcontract work to be procured by Contractor for the Project, the Phase 2 Price Fixed Component shall be adjusted
based upon the increased cost of such Equipment and/or Material or Subcontract plus six percent (6%). 
 iv. * 
 The foregoing notwithstanding, it is understood that any Craft Labor Hours resulting from Contractor’s error, negligence, defects or
deficiencies in engineering or in the performance of the Work (beyond that which is normal re-work activity customary in the industry in accordance with Prudent Industry Practices) shall not be included in the calculation of actual Craft Labor Hours
expended for determining if and to what extent the Craft Labor Hour Target has been exceeded. Similarly, to the extent that the aggregate actual Craft Labor Hours for Phase 2 Work included in the original Craft Labor Estimate are below the Craft
Labor Hours Target, such under run shall be to Owner’s benefit and no adjustments shall be made unless and until the entire under run in Craft Labor Hours has first been exhausted and then Craft Labor Hours exceed * of the Craft Labor
Hour Target. 
 5.2.7 Reconciliation of Actual Craft Labor Hours to Craft Labor Hour Target. In the event that field
Craft Labor productivity for performing the Phase 2 Work is different than the Craft Labor Hour Target for Phase 2, such variances shall be reconciled as follows: 
 a) * 
 The foregoing
notwithstanding, it is understood that any expenditure of Craft Labor hours resulting from Contractor’s error, negligence, defects or deficiencies in engineering or in the performance of the Work (beyond that which is normal re-work activity
customary in the industry in accordance with Prudent Industry Practices) shall not be included in the calculation of actual field hours expended for determining if and to what extent the Craft Labor Hour Target has been exceeded and shall not be
included in (or paid by Owner as part of) the Phase 2 Price Reimbursable Component.

 5.7 Withholding to Protect Owner from Loss. 
 5.7.1 Withholding. Owner may, without prejudice to any other rights Owner may have hereunder, after issuing a Notice to Contractor,
also withhold all or any portion of any payment to such extent as may be necessary in Owner’s reasonable judgment to protect Owner from losses, costs, expenses or damages for which Contractor is liable due to: 
 (a) unpaid overdue amounts due to Owner by Contractor under this Agreement; and 
 (b) Contractor Liens (with respect to Liens filed by Subcontractors) for which, 20 days after having received knowledge thereof,
Contractor has failed to remove the Contractor Lien or provide a Contractor Lien Bond. 
 5.7.2 Lien Title Indemnity.
Notwithstanding Section 5.7.1, Owner shall release any payments withheld because of any Lien if Contractor obtains a Contractor Lien Bond; provided, however, other than compliance with its obligation to deliver a Contractor
Lien Bond, the posting of such Contractor Lien Bond does not relieve Contractor of any other obligations (including its indemnity obligations) under this Agreement. 
 5.8 Delinquent Payments. Payments not made when due will bear interest from the due date thereof until the date paid at the Late Payment Rate. For the avoidance of doubt, any portion of any payment that is
disputed and not paid in accordance with the provisions of this Agreement and subsequently determined to be payable on the original due date thereof will bear interest in accordance with the foregoing from the date such portion of the disputed
amount was due (assuming there had been no Dispute) until the date of actual payment. 
 5.9 Contractor Liens. Contractor shall cause
each Contractor Lien to be canceled or discharged of record or furnish Owner with a Contractor Lien Bond. If Contractor does not promptly satisfy such Contractor Lien or fails to provide Owner with a Contractor Lien Bond in lieu thereof, in any
event within the period specified in Section 5.7.1(b), then Owner may, after Notice to Contractor and expiration of 10 days after Contractor’s receipt of such notice, cure or release such Contractor Lien by payment of money or
otherwise, and, if Owner arranges a Contractor Lien Bond with respect to such Contractor Lien, Contractor shall reimburse Owner for the reasonable cost of arranging such Contractor Lien Bond within 30 days after a request therefor by Owner, if and
to the extent that Contractor was not justified in withholding the payment underlying such Lien.

mechanical or electrical integrity) of the Project or compliance with Applicable Legal Requirements, including Permits, and which remain to be performed to complete the Work, (b) the proposed time limits within which Contractor will complete
such remaining Work, and (c) Contractor’s plan to complete such Work on or before the Target Final Completion Date. Upon its receipt of such list, Owner shall review the same and notify Contractor of any proposed revisions thereto. Such
list shall be subject to additions and deletions as systems are added or completed, or as defects are identified by the Parties. Owner’s Authorized Representative and Contractor’s Authorized Representative shall then meet, consult in good
faith and, prior to the Substantial Completion Date, agree upon the final list and plan, including the approved time limits within which Contractor shall perform such remaining Work and the value of the items of Work described therein (the
“Punch List”). Once the items on the Punch List have been identified, Contractor shall promptly begin working on the items thereon. The plan for completing the Work specified in the Punch List may be amended by Contractor at any
time prior to Final Completion upon Notice to Owner to reflect the progress of completing such Work; provided, however, any such amendment to the plan must reasonably provide for the completion of all such Work by the Target Final
Completion Date. The review and comment by Owner or its representatives of any matter relating to the Punch List will not relieve Contractor of its obligations under this Agreement.

 6.4 Transfer of Possession and Control to Owner. 
 6.4.1 Possession and Control. On or before the Substantial Completion Date, Contractor and Owner shall agree upon a schedule of the
dates and times, if any, when Contractor will require a partial or complete shut down of the Project or the imposition of operating restrictions on the Project in order to complete the Work (other than the Punch List) under this Agreement;
provided, however, such schedule will (a) provide for such partial or complete shutdown of, or the imposition of operating restrictions on, the Project only during a scheduled outage, if any, or off-peak hours so as to accommodate
Owners’ reliance on the activated carbon and electrical output from the Project, and (b) be subject to the dispatch requirements of the Transmission Provider. Subject to Section 6.2.4, on the Substantial Completion Date or the
date of termination of this Agreement, if earlier, Owner shall take and thereafter be solely responsible for the care, custody, control, operation, and maintenance of the Project. Following transfer of possession and control of the Project to Owner,
Contractor (and its Subcontractors and the Owner Suppliers) will have reasonable access to the Project consistent with the schedule established in accordance with, and the other requirements of, this Section 6.4 and the cooperation of
Owner as necessary for Contractor to complete any Work still remaining to be performed hereunder, including the Punch List items. Following issuance of the Certificate of Substantial Completion to Owner, Contractor shall comply with health, safety
and security rules of Owner supplied reasonably in advance (including permit-to-work procedures and requirements), which will be consistent with Prudent Industry Practices, regarding activities at the portion of the Project and the Project Site so
transferred and shall coordinate its activities at such portion of the Project and the Project Site with any other Person performing work, operation, maintenance or other activities at such location.

Performance Test report must be delivered to Owner in accordance with Appendix C. Contractor shall include sufficient results of testing in the preliminary test report to allow Owner to reasonably determine that there is a high
probability that the final test results will confirm that the applicable conditions of Substantial Completion have been achieved. As soon as practicable, but in any event within 10 Business Days after receipt of Notice by Owner and the Owner
Engineer, Owner shall give Notice to Contractor either concurring with, indication it cannot confirm concurrence, or rejecting the Completed Performance Test report and stating its reasons for such Notice, as the case may be. Such procedure shall be
repeated until Contractor submits a Notice demonstrating Project performance necessary to achieve Substantial Completion or Final Completion, as applicable. Subject to Article 17, if Contractor’s Notice of a Completed Performance
Test is rejected by Owner, such test shall not constitute a Completed Performance Test.

 7.3.2 Reliability Test. After Contractor believes that the Reliability Requirement
has been achieved, it shall give Notice to Owner and the Owner Engineer of its belief and the specific TBD hour period of Project performance upon which it bases its belief (such period to constitute the “Reliability Test”).
Such Notice will be accompanied by a final test report which shall include both the raw data on which the report is based and Contractor’s analysis of such data. As soon as practicable, but in any event within 5 Business Days after receipt of
Notice by Owner and the Owner Engineer, Owner shall give Notice to Contractor either concurring with, or rejecting, the report and stating its reasons for rejection of such Notice, as the case may be. Such procedure shall be repeated until
Contractor submits a Notice demonstrating Project performance necessary to achieve the Reliability Requirement. Subject to Article 17, if Contractor’s Notice of a Reliability Test is rejected by Owner, such test shall not constitute
a Reliability Test. 
 7.3.3 Individual Test Reports. After Contractor has completed any Performance Test, it shall
provide to Owner a preliminary test report for each such test as soon as reasonably practicable but in no event more that 24 hours after the completion of such test (or as soon thereafter as such reports are first available to Contractor) providing
a summary of such test and including all raw data taken during such test and, if Contractor believes such test has been passed, a final test report within 30 days thereafter. If Contractor believes such test has been passed, Contractor shall include
sufficient results of such testing in the preliminary test report to allow Owner to determine that there is a high probability that the final test results will confirm that such test has been passed. Contractor shall not be required to provide an
individual test report (preliminary or final) pursuant to this Section 7.3.3 if the results of such test are, at the same time, to be included in the reports to be provided by Contractor pursuant to Section 7.3.1. 

7.4 Repetition of Tests. (a) If a Performance Test is not conducted in accordance with the requirements of this Agreement or fails to
demonstrate that the Project meets or exceeds the Performance Requirements required for Substantial Completion, then Contractor shall, as part of the Work, (a) promptly take all actions necessary to correct any deficiencies in order to cure
such failure, and (b) re-perform the Performance Tests as many times as required until achievement of the applicable Performance Requirements is demonstrated pursuant to this Agreement, subject, when applicable, to the determination pursuant to
Section 8.2.1 to add Buydown Amounts to the Total Installed Cost. 
 (b) If a Change Event causes a failure to pass a Performance
Test, then Contractor work will be reimbursed on a time and materials basis for the conduct of a re-test. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 83 of 133

 7.5 Re-Setting of Project. Promptly after the completion of any Performance Test, Contractor shall
perform whatever Work is necessary, including re-setting of equipment (to the extent settings were allowed to be changed during any Performance Test) and repairs of damage or modifications caused by testing, to ensure that the normal operating
control settings and configurations for the Project are maintained. 
 7.6 Operation of the Project. In the event that either
(i) Contractor has not conducted a Performance Test within thirty (30) days after the “Mechanical Completion Date” or (b) a Performance Test has been conducted within such time but the requirements of Sections 6.2.1
(b) and (c), above, have not been met, then Owner shall have the right to operate and maintain the Project prior to completion of the Performance Test to produce activated carbon and electricity for the benefit of Owner, subject to the
following conditions: 
  

	 	(a)	All costs of such operation and maintenance that would be borne by Owner after Final Completion (including but not limited to costs of supplies, feed stock, chemicals, fuels and
lubricants, operating personnel, overhead, debt service, taxes and transportation) shall be borne by Owner during this period of interim operation and maintenance, and 

  

	 	(b)	This right of Owner shall not operate to, or be construed to, delay, limit, prevent or in any way impede Contractor’s right to control the Project in order to conduct
additional Performance Tests at its discretion.

 ARTICLE 8 
 PERFORMANCE AND COMPLETION 
 REQUIREMENTS, LATE SUBSTANTIAL 
 COMPLETION DAMAGES AND BONUS 
 AMOUNTS

 8.1 Performance and Completion Requirements. 
 8.1.1 Performance Requirements. The Project shall meet the Performance Requirements described in Sections 8.1.1.1
through 8.1.1.7 when tested pursuant to a Completed Performance Test performed in accordance with the requirements of Appendix C and the other provisions of this Agreement and Applicable Legal Requirements. In addition to the
foregoing, the Project must be capable of continuous commercial operations in compliance with Applicable Legal Requirements. The Levels of Performance Requirements shall be established by Phase 1 Work. 
 The Requirements set forth in Sections 8.1.1.1 through 8.1.1.7 are the “Performance Requirements”. 
 8.1.1.1 Activated Carbon Throughput Minimum. The Activated Carbon Throughput from the Project will not be less than
[            ] tons/day, when corrected to Design Conditions (the “Activated Carbon Production Requirement”)] 
 8.1.1.2 Activated Carbon Quality Specification. The Activated Carbon produced from the Project will be of a quality at least as
good as the specifications set forth in Appendix R (the “Activated Carbon Specification Requirement”). 
 8.1.1.3 Limestone Consumption Requirement. Limestone consumption will not result in a Ca/S ratio in excess of [            ], when corrected to Design Conditions (the
“Limestone Consumption Requirement”). 
 8.1.1.4 Net Electrical Output Requirement. The Net Electrical
Output from the Project will not be less than [            ] kilowatts, when corrected to Design Conditions (the “Net Electrical Output Requirement”). 
 8.1.1.5 Environmental Compliance Requirement. The Project will comply with all requirements of the emissions table set forth in
Appendix C (the “Environmental Compliance Requirement”). 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 85 of 133

 8.1.1.6 Noise Level Requirements. The Project will comply with the noise
limitations and requirements set forth in Appendix C and Applicable Legal Requirements. 
 8.1.1.7 Reliability
Requirement. Contractor shall perform the Work with the objective that actual Project Reliability will be              percent
(        %) as determined in accordance with the TBD Reliability Test performed on or before the Substantial Completion Date (the “Reliability Requirement”). 
 8.1.2 Required Substantial Completion Date. Contractor shall perform the Work with the objective that the Substantial Completion
Date for the Project will occur on or before the Early Required Substantial Completion Date. 
 8.1.3 Target Final
Completion Date. Contractor shall perform the Work with the objective that Final Completion of the Project will occur on or before the Target Final Completion Date. 
 8.2 Late Substantial Completion Damages and Buydown Amounts. 
 8.2.1 Late
Completion Liquidated Damages. If Substantial Completion does not occur on or before the Required Substantial Completion Date, Contractor shall pay liquidated damages to Owner for such delay for each and every day that elapses between the
Required Substantial Completion Date and the date on which Substantial Completion occurs (“Late Substantial Completion Damages”). The per-day Late Substantial Completion Damages payable pursuant to this Section shall be $
             per day [less net income from product generated by the Project after deducting all costs, including the full amount of Owner’s carrying and other cost for debt,
such net income calculated on a daily basis] provided if the Activated Carbon Production Requirement has been achieved and the Project is operated so as to produce activated carbon in an amount at least equal to such Requirement level on such day,
then the Late Substantial Completion Damages for such day shall be reduced to $            . Notwithstanding the payment of Late Substantial Completion Damages, Contractor shall
continue to expeditiously perform, repair, replace and fix the Work until Substantial Completion is achieved. The Parties agree that it would be extremely difficult and impracticable to determine precisely the amount of actual damages that would be
suffered by Owner as a result of Contractor’s failure to achieve the applicable Required Substantial Completion Date. The Parties further agree that the Late Substantial Completion Damages are a fair and reasonable substitute therefor. The
Parties agree that each is estopped to argue the invalidity, unenforceability or otherwise question the reasonableness of the Late Substantial Completion Damages, as they represent the allocation of risk between the Parties and the basis of the
bargain. Late Substantial Completion Damages will not

		 		 	Page 86 of 133

 
(i) limit Contractor’s liability for its failure to perform any of its other obligations hereunder, including Defects in the Work, or its
obligations to achieve Final Completion, or (iii) limit Owner’s remedies for Contractor’s failure to perform any of its other obligations hereunder. Liquidated Damages are understood to be an estimate of actual damages and not a
penalty, and to represent Contractor’s sole liability and Owner’s sole remedy for the deficiency specifically giving rise to the Liquidated Damages liability. 
 8.2.2 Late Substantial Completion Damages. In the event that a failure to achieve Substantial Completion by the Required
Substantial Completion Date is attributable (in whole or in part) to one or more Owner Supplier(s), Contractor shall give notice to Owner to that effect (together with reasonable supporting documentation) and Contractor shall assist Owner in
recovering the applicable Late Substantial Completion Damages from the responsible Owner Supplier(s) under the terms of the Owner Contract(s) in question. 
 8.3 Early Substantial Completion Bonus. If the Substantial Completion Date occurs before the Required Substantial Completion Date, then Contractor will earn a bonus equal to
$             per day for each day by which the Substantial Completion Date is earlier than the Required Substantial Completion Date (the “Early Substantial Completion Bonus
Amount”); provided, however, that the maximum amount of the bonus payable by Owner pursuant to this Section 8.3.1.1 shall be $            .

 ARTICLE 9 
 THE WARRANTY PERIODS 
 9.1 General Warranty of Work, Materials and Equipment. Contractor
hereby warrants to Owner that:
  

	 	(a)	the Work will be designed, furnished and performed (i) in accordance with Professional Standards, and (ii) in compliance with the provisions of this Agreement and all
Applicable Legal Requirements in effect on the Effective Date or, in respect of the Work described in a Change Order, the date of such Change Order; 

  

	 	(b)	the Work will be free from Defects in workmanship and material; and 

  

	 	(c)	all Contractor Equipment and Materials provided by Contractor will be new and unused at the time of their delivery to the Project Site, except reconditioned special tools approved
by Owner as provided in Section 6.2.1(e). 

 9.2 Owner Supplier Work. Until Substantial Completion,
Contractor shall: 
  

	 	(a)	assist Owner in enforcing Owner’s warranty rights under Owner Contracts and managing the warranty response by Owner Suppliers; and 

  

	 	(b)	perform such construction, disassembly and testing and related services as are necessary to complete warranty repairs or corrections of defects manifest in Owner Suppliers’
Scope under the Owner Contracts. 

 9.3 Nonconforming Work. During the applicable Warranty Period, Owner, Owner
Agents, Owner’s Authorized Representative, and/or other Persons that Owner has given Contractor Notice that such Persons are authorized by Owner to act on its behalf (“Owner Authorized Parties”), to the extent of their
authority, shall have the authority to require Contractor to re-perform, repair or replace any Work (including Contractor Equipment and Materials) that does not conform to the requirements of Section 9.1 (“Warranty
Defect”), including the obligation to perform any Work or activity necessary to access the Work to be re-performed, repaired or replaced and any Work or activity necessary to recover, finish or otherwise cover and return to full operating
status the Work to be re-performed, repaired or replaced; provided, however, neither the identification of a Warranty Defect nor any decision made by Owner in good faith either to exercise or not to exercise their rights under this
Article 9, will give rise to any duty or responsibility of Owner. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 88 of 133

 9.4 Contractor’s Warranty Work. If Owner gives Contractor Notice of a Warranty Defect during
the applicable Warranty Period, Contractor shall, at its sole expense, promptly (consistent with the access provided by Owner) correct such Warranty Defect by repair or replacement at Contractor’s sole option, which repair or replacement will
include all access and restoration Work associated therewith. To the extent that correction of the Warranty Defect involves the re-performance, repair, re-supply or replacement of any item supplied or performed pursuant to an Owner Contract,
Contractor shall assist Owner in procuring such re-performance, repair, re-supply or replacement by the Owner Supplier and the costs incurred by Owner on account thereof to correct such Warranty Defect will be added to the Total Installed Cost. The
plan for the repair or replacement of a Warranty Defect shall be made in consultation with Owner and Contractor shall schedule any Work in respect of the Warranty Defect during off-peak hours consistent with (a) Owner’s operating
requirements so as to minimize, to the maximum possible extent, loss of production or use of any portion of the Project. Contractor shall use commercially reasonable efforts to conduct its Work associated with a Warranty Defect on a timely basis
(inclusive of overtime) if Owner reasonably determines that an expedited schedule is necessary to avoid or minimize the effects on activated carbon production. Except as provided above and subject to Section 9.12, Contractor shall bear
all costs and expenses associated with correction of any Warranty Defect notified to Contractor during the applicable Warranty Period. Such costs shall include the costs of necessary disassembly, transportation, reassembly, retesting, reworking,
repair, or replacement of such Warranty Defect, engineering, and the costs of testing reasonably required to verify that the repaired or replaced Work conforms to the applicable Warranties and the requirements of this Agreement. Contractor shall
collect and assemble all warranty documents and deliver them to Owner prior to the expiration of the applicable Warranty Period or termination of this Agreement, whichever is earlier. Any repair and replacement performed by Contractor pursuant to
this Article 9 shall constitute Work and the provisions of this Article 9 apply to such Work. 
 9.5 Warranty
Periods. 
 9.5.1 Duration. The “Warranty Period” commences on the Substantial Completion Date and
expires on the second anniversary of the Substantial Completion Date. If any Work is required to be repaired, replaced, or otherwise corrected pursuant to this Article 9, the Warranty Period for such repaired, replaced or corrected Work
will be 2 years from the date that such repair, replacement, or correction is completed; provided, however, in no case will the Warranty Period for such repaired, replaced or corrected Work extend beyond the 4th anniversary of the
Substantial Completion Date. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 89 of 133

 9.5.2 Transfer. Upon the earlier of (a) the termination of this Agreement, or
(b) the end of the Warranty Period, Contractor shall, promptly and without any other obligation on the part of Owner, transfer to Owner all Subcontractor warranties that extend beyond the applicable Warranty Period under this
Article 9. Prior to transferring the extended warranties to Owner, Contractor shall maintain and enforce such warranties and shall not materially modify or amend such warranties without the prior written consent of Owner, which may be
withheld for any reason. 
 9.6 Subcontractor Warranties. Contractor shall use its commercially reasonable efforts to obtain other
warranties, including additional and extended warranties, for the benefit of Contractor and Owner from Subcontractors in relation to their respective portions of the Work. Copies of all such warranties obtained by Contractor shall be provided to
Owner promptly upon execution of the applicable Contractor Subcontract by Contractor. Such warranties will be written to survive Contractor’s tests, inspections and approvals and will be assignable, as provided in the next sentence, to Owner
without Subcontractor’s consent. On the earlier of (a) the Substantial Completion Date or (b) the termination of this Agreement, Contractor shall assign to Owner any Subcontractor warranty for Work or Equipment provided by Contractor
hereunder. 
 9.7 Root Cause Repairs. If there are 2 or more failures of any component during the Warranty Period (either original or
as may be extended as a result of failures during the original Warranty Period), then, at the request of Owner, Contractor shall perform a root cause analysis investigation of such failures and, if such investigation (a) reveals a Warranty
Defect, make such repairs, replacements or adjustments necessary to correct the Warranty Defect; or (b) reveals a defect in Owner Suppliers’ Scope (“Owner Supplier Defect”), provide the assistance described in
Section 9.2 on a cost reimbursable basis in respect thereof if requested by Owner. As requested by Owner, Contractor shall submit, as part of its root cause analysis investigation and report, all design and performance calculations
related to such component failure. IF SUCH FAILURE IS CAUSED BY A DEFECT IN OWNER SUPPLIER’S SCOPE, ALL COST ASSOCIATED WITH THE ROOT CAUSE ANALYSIS SHALL BE REIMBURSABLE TO CONTRACTOR. 
 9.8 Cure Rights of Owner for Breach of Warranty. Promptly upon receipt by Contractor of Notice from Owner identifying a Warranty Defect (which
period will be as short as possible, but in no event longer than 2 Business Days if the Project is forced out of service or is operating on a restricted basis), Contractor shall give Notice to Owner of when and how such Warranty Defect will be
remedied; provided, however, that Contractor will conduct its cure activities in a commercially reasonable and prompt manner; provided, further, in cases of imminent danger to life or property or forced outage of the
Project, Contractor shall make best efforts to remedy such Warranty Defect as soon as possible, taking into consideration mobilization to the Project Site and availability of Contractor Personnel. If Contractor does not begin and diligently proceed
to complete said remedy within the time period specified in the corrective approach, Owner after Notice to Contractor, shall have the right to perform or to have performed by third parties the necessary remedy, and the costs thereof (including a
warranty thereon) shall be borne by Contractor; provided, that any such warranty Work performed by a third party shall no longer be subject to the provisions of Section 9.1. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 90 of 133

 9.9 Title to Warranty Work. Title to all Contractor Equipment and Materials provided in performing
warranty Work, including all repairs, replacements and corrections, will pass to Owner immediately upon the inclusion thereof into the Project and otherwise will be subject to the provisions of Section 2.5.1. 
 9.10 Exclusions. The warranty set forth in Section 9.1 will not apply to Defects in, damage to or breakdown of the Project after care,
custody and control has been turned over to Owner in accordance with this Agreement to the extent such Defect, damage or breakdown is caused by: 
  

	 	(a)	Owner’s failure to operate or maintain the Project in accordance with Prudent Industry Practices; 

  

	 	(b)	Owner’s failure to give Contractor Notice of a Warranty Defect actually known to Owner promptly after its discovery by Owner; 

  

	 	(c)	continued operation of the Project following identification of the Defect, to the extent such continued operation exacerbates the Defect or creates additional Defects that require
warranty Work; 

  

	 	(d)	normal wear and tear; or 

  

	 	(e)	Owner’s denial of Contractor’s reasonable request for access to the Defect for the performance of Contractor’s warranty obligations, such access to be consistent with
Project operations and Prudent Industry Practices. 

  

	 	(f)	Exclusions contained in purchase documents of Contractor’s equipment vendors that are approved by Owner.

 9.11 Primary Liability. Subject to Section 9.10(f) above, Contractor has primary liability with respect to the warranties set forth in
Section 9.1 of this Agreement, whether or not any Defect or other matter is also covered by a warranty of a Subcontractor, and Owner needs only look to Contractor for corrective action. The refusal of a Subcontractor or other third party
to correct defective Work will not excuse Contractor from its liability as to the warranties provided herein.

		 		 	Page 91 of 133

 9.12 General Limitations on Warranties and Remedies. THE REMEDIES PROVIDED IN THIS
ARTICLE 9 ARE THE EXCLUSIVE REMEDIES OF OWNER AND THE SOLE OBLIGATION AND LIABILITY OF CONTRACTOR ARISING OUT OF CLAIMS FOR WARRANTY DEFECTS OR DEFECTS IN THE WORK IDENTIFIED AFTER THE SUBSTANTIAL COMPLETION DATE FOR THE APPLICABLE UNIT.
EXCEPT FOR THE EXPRESS WARRANTIES SET FORTH IN THIS ARTICLE 9, CONTRACTOR DOES NOT MAKE ANY OTHER EXPRESS WARRANTIES, OR ANY IMPLIED WARRANTIES, OF ANY KIND WHATEVER RELATING TO THE WORK TO BE SUPPLIED BY CONTRACTOR UNDER THIS AGREEMENT OR TO THE
FACILITY, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE, CUSTOM OR USAGE OR OTHERWISE.

 ARTICLE 10 
 CHANGES 
 10.1 Changes. Without invalidating this Agreement, by issuance of a written order,
in the form set forth in Appendix I-5, (each such order, a “Change Order”) (a) changes to the Work or the Project may be made, including any addition to, deletion from, suspension of or other modification to the
quality, function or intent of the Work or the Project, and (b) to the extent specifically provided for in this Article 10, adjustments may be made to the Project Schedule (including the Target Contract Dates), Performance Targets,
the Phase 2 Price, the Milestone Payment Schedule or the other obligations or liabilities of the Parties under this Agreement (all of the foregoing, “Changes”). Changes may only be authorized by Change Orders issued in accordance
with this Article 10; provided, however, Contractor shall not be required to make any Change that (a) requires it to perform Work that is not rationally or functionally related to the Work described in this Agreement
on the Effective Date, or (b) requires Contractor to transport and dispose of Owner Hazardous Substances for which Owner is responsible under this Agreement. Except for an emergency in which imminent harm to Persons or damage to property can
only be avoided by proceeding with a Change without approval by Owner, in no event shall Contractor unilaterally undertake a Change until (i) a Change Order has been approved by Owner, or (ii) if a disagreement exists with respect to a
proposed Change Order as described in Section 10.2.2, Contractor has received Notice from Owner to proceed under protest. 
 10.2 Procedure for Changes. 
 10.2.1 Changes Initiated by Contractor. Within 10 Business Days after
Contractor becomes aware of any circumstances, including Change Events, which Contractor has reason to believe may necessitate a Change, Contractor shall issue to Owner a “Change Order Request.” All Change Order Requests will
include, to the extent then reasonably available (and thereafter promptly updated as information becomes available) to provide, documentation sufficient to enable Owner to determine: (a) the factors necessitating the possibility of a Change;
(b) the impact the Change is likely to have on the Phase 2 Price Fixed Component; (c) the impact the Change is likely to have on the timely achievement of the Project Schedule (including the Required Contract Dates, as applicable);
(d) the impact the Change is likely to have on the Craft Labor Hour Target, (e) the impact the Change is likely to have on the Phase 2 Price Reimbursable Component, (f) the impact the Change is likely to have on any of the other
obligations or liabilities of the Parties under this Agreement, and (g) such other information which Owner may reasonably request in connection with such Change; provided, that the information required by clause (a) is the only
essential element to be provided within the initial 10 Business Day period. Owner may, but except as provided in Section 10.3 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 93 of 133

 
below will not be obligated to, issue a Change Order pursuant to a Change Order Request. Owner must provide its response to Contractor’s Change Order
Request within 10 Business Days after receipt thereof. Unless otherwise stated by Owner in writing or in the case of an emergency in which imminent harm to Persons or damage to property can only be avoided by proceeding with work outside the Work,
any work outside the Work described in this Agreement performed by Contractor prior to its having received an executed Change Order from Owner will be considered unauthorized work and will be at Contractor’s sole risk and expense. In no event
will a Recovery Plan or other document or Submittal constitute a Change Order under this Agreement, unless such document is clearly titled a “Change Order” and otherwise satisfies all of the requirements of a Change Order
under this Article 10. 
 10.2.2 Changes Initiated by Owner. If Owner desires to make a Change constituting
a modification to the quality, function, intent or scope of the Work (including aspects of the Work relating to the operation or care, custody and control of the Project), it shall submit a “Change Order Notice” to Contractor.
Contractor shall promptly review the Change Order Notice and provide Notice to Owner of the estimated cost to develop the Change Order, which Notice will be accompanied with reasonable supporting documentation. Within 10 Business Days (or if 10
Business Days is not reasonably adequate, then as promptly thereafter as practicable) after Owner and Contractor agree to the cost of developing the Change Order estimate, Contractor shall provide Owner with Notice of the options for implementing
the proposed Change (including, if possible, any option that does not involve an extension of time or additional cost) and the estimated effect(s), if any, that each such option would have on the Performance Requirements, Phase 2 Price Fixed
Component, Craft Labor Hour Target, Phase 2 Price Reimbursable Component, the Milestone Payment Schedule, the Project Schedule (including the Required Contract Dates), and any of the other obligations or liabilities of the Parties under this
Agreement. The timing of Work to be performed pursuant to a Change directed by Owner must be consistent with resources available to Contractor. Based upon such information, Owner may, but will not be obligated to, issue a Change Order making a
Change based upon such Change Order Notice. If Owner and Contractor cannot promptly reach agreement on the matters listed in the Change Order Notice, or cannot agree that the matters under discussion constitute a Change, Owner may, at its sole
discretion, order Contractor by Notice to promptly proceed to complete the Change in accordance with Owner’s interpretation of the matter under Dispute. Contractor may refuse to implement a Change ordered pursuant to this
Section 10.2 only if such Change (a) would constitute a violation of Applicable Legal Requirements, (b) requires Contractor to perform Work that is not rationally or functionally related to the Work, or (c) requires
Contractor to transport and dispose of Hazardous Substances for which Owner is responsible under this Agreement.

		 		 	Page 94 of 133

 10.3 Change Events. Except as otherwise provided herein, if and to the extent that: 
  

	 	(a)	a Force Majeure event or Change of Law (other than any Excluded Change of Law); 

  

	 	(b)	a suspension of the Work in accordance with this Agreement (for an improperly issued stop work order); 

  

	 	(c)	adverse impact on the Work pursuant to Section 2.2.13.3 or Section 3.9, other than for a Hazardous Substance for which Contractor is responsible;

  

	 	(d)	a delay or other adverse impact arising from a discovery pursuant to Section 2.5.5; 

  

	 	(e)	a delay or failure of Owner or an Owner supplier to perform its obligations in accordance with this Agreement or an Owner Contract (except in either case to the extent such delay or
failure is attributable to Contractor or Subcontractors). This provision applies, without limitation, to Owner Contracts assigned for management to Contractor; 

  

	 	(f)	a change in Owner’s policies and procedures after Substantial Completion that adversely affect the performance of the Work; 

  

	 	(g)	any Separate Contractor of Owner, any of the Engineers, or any other designee or invitee of Owner performing work on the Project Site fails to comply with the reasonable
coordination requirements Contractor is entitled to impose under this Agreement, causing a material interference with the performance of the Work, except to the extent such interference results from the fault of Contractor or its Subcontractors;

  

	 	(h)	Owner’s direction to Contractor to make an award to a local supplier pursuant to Section 2.8.7 which award causes (i) a delay or (ii) a cost differential
when compared to the cost that would have been incurred had the award been made to the supplier recommended by Contractor; 

  

	 	(i)	delay in issuance of the Phase 2 Notice to Proceed after *; 

  

	 	(j)	a delay or other net impact on Contractor resulting from a change order executed or option exercised under an Owner Contract, except to the extent arising from failure of Contractor
(or its Subcontractors) to perform obligations in accordance with this Agreement; 

  

	 	(k)	a delay or other adverse impact on Contractor resulting from Owner’s exercise of its right to prevent the specific exercise of Contractor’s authority under
Appendix M, except to the extent attributable to the fault of Contractor or its Subcontractors; 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 95 of 133

	 	(l)	an Owner Test Interruption occurs. 

 (each, a “Change
Event”), causes Contractor to suffer a delay in the critical path of the Work, increases Contractor’s costs in performing the Work or otherwise increases the costs of the Project, impacts the ability of the Project to achieve the
Performance Requirements, or adversely impacts Contractor’s ability to perform any of its other material obligations under this Agreement, then Owner shall, by Change Order, equitably adjust the Target Contract Dates in accordance with
Section 10.4, equitably increase the Phase 2 Price Fixed Component in accordance with Section 10.5, equitably adjust the Milestone Payment Schedule, equitably increase the Fee (to the extent permitted by
Section 5.1.4), and/or equitably adjust the Performance Requirements or other obligations of Contractor so adversely impacted. 
 10.4 Changes Involving Schedule Extensions. To the extent that Contractor demonstrates that a Change (or the Change Event necessitating a Change) as described in Section 10.2.2 or Section 10.3 will delay the
achievement of the Target Completion Dates, then Owner shall cause a Change Order directing such Change (or resulting from such Change Event) to equitably extend the Target Contract Dates to account for the delay in the critical path of the Work.

 10.5 Changes to the Phase 2 Price Fixed Component. In the event a Change Order or Change Event under Article 10
increases or decreases the cost of the Work or the cost of the Project, subject to Contractor’s reasonable efforts to mitigate the impact of such event, an equitable adjustment shall be made to the Phase 2 Price Fixed Component. 
 10.6 Continued Performance Pending Resolution of Disputes. Notwithstanding and pending resolution of any Dispute with respect to a Change,
Contractor shall proceed on a time and materials basis, upon receipt of Notice from Owner, with the performance of any Change Order issued by Owner. If Owner and Contractor cannot reach agreement on the schedule adjustment or estimated cost of the
Change within a reasonable period (not to exceed 15 days after Contractor is ordered to proceed under protest) either Party may submit the matter for dispute resolution pursuant to Article 17. 
 10.7 Options for Implementing Changes. Whenever there are different possible Changes that can be made in response to a Change Event and those
Changes have different effects on the Project Schedule (including the Target Contract Dates), Phase 2 Price Fixed Component, the Craft Labor Hour Target, the Phase 2 Price Reimbursable Component, Performance Requirements or other 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 96 of 133

 
obligations or liabilities of the Parties under this Agreement, then Owner may in its sole discretion (but consistent with the objective of achieving the
lowest Total Installed Cost) select from among such Changes, with the concomitant adjustments to the Project Schedule (including the Required Contract Dates), Phase 2 Price Fixed Component, the Craft Labor Hour Target, the Phase 2 Price Reimbursable
Component, and Performance Requirements and other obligations or liabilities of the Parties under this Agreement in accordance with this Article 10. 
 10.8 Documentation. All claims by Contractor for adjustments to the Phase 2 Price Fixed Component, the Craft Labor Hour Target, the Phase 2 Price Reimbursable Component, the Fee, Performance Requirements,
Project Schedule (including the Required Contract Dates) and/or other obligations or liabilities of the Parties under this Agreement as a result of any Change shall be supported by verifiable detailed documentation provided to Owner.

 11.1 Force Majeure Event. As used in this Agreement, an event of
“Force Majeure” will mean any event that: (a) prevents or hinders the affected Party (the “Affected Party”) from performing its obligations under this Agreement or complying with any conditions required of it
under this Agreement, resulting in an actual delay in the performance of the Work, increases the cost of performing the Work, or otherwise materially and adversely affects the Affected Party’s performance hereunder, (b) is beyond the
reasonable control of and not the result of the fault or negligence of the Affected Party (including such Affected Party’s Personnel), and (c) could not have been prevented by the exercise of reasonable diligence by the Affected Party or
its Personnel or Subcontractors. 
 For purposes of clause (b) above, the following events shall, by way of example, be considered to be
beyond the reasonable control of an Affected Party: acts of God, war, civil insurrection, epidemic, earthquake, tornado, quarantine, hurricane and other natural disasters, terrorism and sabotage (in each case, domestic and foreign) and the threat
and results thereof, public disorder, lightning and other abnormal or severe climatic conditions, national or regional strikes or labor stoppages, strikes or labor stoppages by employees of Suppliers of Specially Manufactured Equipment, and imminent
threat of any of the foregoing that could reasonably affect the safety or security of individuals on, or damage to, the Project Site. 
 In
no instance will the following be considered events beyond Contractor’s reasonable control or constitute a Force Majeure event: (i) strikes or labor disturbances involving the Personnel of Contractor or any of its Subcontractors at the
Project Site (unless such strike or labor disturbance is national or regional in nature or as otherwise provided in Section 2.17 due to actions of Owner or entities acting on its behalf), (ii) weather other than as described in the
second paragraph of this Section 11.1, (iii) any delay or failure of Contractor to obtain Equipment or Materials for the Project because of the delay or failure of any Subcontractor to perform any obligation to Contractor, unless
such delay or failure is caused (A) by strikes or labor stoppages by employees of the Supplier of Specially Manufactured Equipment, or (B) by an independent event of Force Majeure, (iv) the failure of or delay in delivery in the
issuance of Contractor’s Permits, unless such delay or failure is caused by an independent event of Force Majeure, (v) Equipment and Materials failure, unless such failure is caused by an independent event of Force Majeure,
(vi) domestic and/or foreign transportation delays, unless such delays are caused by an independent event of Force Majeure, or involve Specially Manufactured Equipment or (vii) Excluded Changes in Law.

 11.2 Burden of Proof. The burden of proof as to whether a Force Majeure event has occurred and the
associated relief will be upon the Party claiming relief from such event. 
 11.2.1 Excused Performance. The Affected
Party will not be held in default or be liable for delay or failure in performing its obligations hereunder because of a Force Majeure event if, and to the extent that (a) the Affected Party has taken reasonable alternative measures to mitigate
the consequences thereof, and (b) such Force Majeure event is not the result of any failure of the Affected Party to perform any of its obligations under this Agreement; provided, however, the Affected Party gives Notice within 10
Business Days after it became aware of the occurrence of such Force Majeure event. Such Notice will, to the extent practicable, specify the nature of the occurrence, the reasons why adjustments to this Agreement should be granted, and the projected
length of the delay occasioned by reason of such Force Majeure event. Within 10 Business Days after submission of such Notice, the Affected Party shall provide a more detailed Notice of the impact of the occurrence, its recovery plan (the
“Preliminary Mitigation Plan”) and a more detailed estimate of the effect on this Agreement. Such Notice will be updated as soon as possible after additional information becomes available to the Affected Party. Strict compliance
with this Section 11.2.1 is required. 
 11.2.2 Scope of Excused Performance. The suspension of performance
resulting from such Force Majeure event will be of no greater scope and of no longer duration than is reasonably required by the Force Majeure event. 
 11.2.3 Prior Obligations and Liabilities. No obligations or liability under this Agreement that arose before the occurrence of the Force Majeure event will be excused (except to the extent adversely impacted by
the Force Majeure event) as a result of the occurrence of such Force Majeure event for any period prior to the occurrence of such Force Majeure event. 
 11.2.4 Continued Performance. The Affected Party shall continue to perform its obligations under this Agreement to the maximum extent possible. When the Affected Party is able to fully resume performance of its
obligations hereunder, the Affected Party shall give Notice to the other Party to that effect and shall promptly resume such performance. 
 11.2.5 No Affect on Payment Obligations. Under no circumstance will an event of Force Majeure excuse a Party’s obligations to make payments when due under this Agreement, unless such Force Majeure event
results in a failure of the Federal Reserve wire system or other failure of the banking system that deprives a Party access to otherwise available funds.

 ARTICLE 12 
 INDEMNIFICATION 
 12.1 Indemnity. To the fullest extent permitted by Applicable Legal
Requirements and subject to Section 12.5, Contractor hereby assumes liability for, and shall indemnify, defend and hold harmless Owner and each Owner and their respective shareholders, members, partners, Affiliates, officers, employees,
representatives, agents, the Engineers, as well as the Financing Parties and their employees, officers, representatives and agents (collectively, the “Owner Indemnitees”) from and against all liability, claims, suits, actions, costs
(including reasonable attorneys’ fees, charges and disbursements), expenses, damages, losses, fines, interest, penalties, assessments, judgments, demands, causes of action, and other litigation of any kind and character (collectively
“Claims”) that may be imposed on, incurred by or asserted against any Owner Indemnitee to the extent arising out of (x) negligence or willful misconduct of Contractor, its Personnel or Subcontractors, and in any way relating to
or arising out of: 
  

	 	(a)	any bodily injury (including death) to any Person; 

  

	 	(b)	any damage to the tangible property of third parties to the extent resulting from or in connection with the negligence or intentional misconduct of Contractor, any Subcontractor or
their respective Personnel or Affiliates; 

 or (y) fines, penalties, and costs imposed by any Governmental Authority because of a
violation by Contractor or its Subcontractors or either Contractor’s or Subcontractors’ Personnel of any Applicable Legal Requirements. 
 12.2 Obligations with Respect to Liens. Contractor shall indemnify, save harmless and defend the Owner Indemnitees from and against any and all Contractor Liens (excepting Liens filed by Owner Suppliers) filed in connection with the
performance of the Work, except to the extent Owner has failed to pay the amount of Compensation properly due to Contractor in accordance with the terms hereof for Work in respect to which a Lien has been filed, including all costs and expenses and
attorneys’ fees, charges and disbursements incurred in discharging or defending such Contractor Liens, if and to the extent that Contractor was not justified in withholding the payment underlying such Lien. Contractor shall cause such
Contractor Lien to be canceled or discharged of record by the filing of a bond or otherwise or furnish Owner with a Contractor Lien Bond. If Contractor does not promptly satisfy such Contractor Lien or fails to provide Owner with a Contractor Lien
Bond in lieu thereof within the period specified in Section 5.6.1(c), then Owner may, after at least 10 days prior Notice to Contractor, cure or release such Contractor Lien by payment of money or otherwise, and if Owner arranges a
Contractor Lien Bond with respect to such Contractor Lien, Contractor shall reimburse Owner for the reasonable cost of arranging such Contractor Lien Bond, within 30 days after request therefor by Owner.

		 		 	Page 100 of 133

 12.3 Obligations with Respect to Intellectual Property. Contractor shall fully indemnify, save
harmless and defend the Owner Indemnitees from and against any and all Claims for the infringement (actual or alleged) or misappropriation of any Intellectual Property, proprietary or confidentiality rights with respect to materials and information
designed, specified or used by any of Contractor or Contractor’s Personnel in performing the Work or in any way incorporated in or related to the Work, unless the infringing item was specified by Owner or arises from the infringement or
misappropriation of any Intellectual Property by an Owner Supplier. If, in any such Claim, a temporary restraining order or preliminary injunction is granted, then Contractor shall make every reasonable effort, by giving a satisfactory bond or
otherwise, to secure the suspension of the injunction or restraining order as soon as possible. If, in any such Claim, the Project, or any part, combination or process thereof, is held to constitute an infringement and its use is enjoined, then
Contractor, at Contractor’s sole option, cost and expense, shall either promptly (a) secure for Owner an irrevocable, royalty free, perpetual, non-exclusive license, at no cost to Owner, authorizing continued use of the infringing process,
item or other Work without impairing the performance or operating cost of the Project, or (b) either replace the affected Work or portion, combination or process thereof with non-infringing, without impairing the performance or operating cost
of the Project, components or parts or modify the same so that they become non-infringing; provided, however, in connection with any such replacement or modification, Contractor shall be responsible for any Work necessary to access the
item to be replaced or modified, and any Work necessary to recover, finish or otherwise cover and return to full operating status the item to be replaced or modified and removing the item to be replaced or modified, or reinstalling the item so
replaced or modified, in each case as and to the extent necessary, to fully complete the replacement or modification of such item into the Project. Furthermore, if such Claim for infringement or misappropriation threatens to affect the operation of
the Project or any portion thereof in the reasonable judgment of Owner, Contractor shall promptly undertake the obligations set forth in the previous sentence. The foregoing notwithstanding, Contractor’s liability under this paragraph for
infringement or misappropriation by vendors or manufacturers supplying manufactured equipment to Contractor shall be limited to the remedies for infringement or misappropriation contained in the purchase documents between Contractor and such vendor
or manufacturer, so long as Contractor includes in such purchase documents an indemnity of Owner by the vendor substantially the same as the foregoing.

 12.4 Owner Indemnity. To the fullest extent permitted by Applicable Legal Requirements and
Section 12.5, Owner hereby assumes liability for, and shall indemnify, defend and hold harmless Contractor and its shareholders, officers, Affiliates, employees, representatives, Subcontractors, and agents (collectively, the
“Contractor Indemnitees”) from and against all Claims that may be imposed on, incurred by or asserted against any Contractor Indemnitee and in any way relating to or arising out of (x) negligence of Owner and in any way
relating to or arising out of: 
  

	 	(a)	any bodily injury (including death) to any Person; 

  

	 	(b)	any property damage (except where the risk of such damages has been assumed by Contractor elsewhere herein); 

  

	 	(c)	either the presence of any Owner Hazardous Substances or the Release or threatened Release of any Owner Hazardous Substances, on or from the Project Site, except to the extent
caused by the Release or threatened Release by Contractor, any Subcontractor or their respective Personnel or Affiliates as described in Section 2.2.13.2; or 

 (y) fines or penalties and the cost of any remedial requirements imposed on Contractor or its Subcontractors because of a violation by Owner or any Owner Personnel of any Applicable Legal Requirements,
provided, however, Owner will not be responsible for paying any portion of a fine that is imposed upon Contractor or its Subcontractors as a result of a prior violation for which Owner was not responsible. 
 12.5 Notice and Legal Defense. Promptly after receipt by a Owner Indemnitee or a Contractor Indemnitee (an “Indemnitee”) of any
Claim or notice of the commencement of any action, administrative or legal proceeding, or investigation in connection with an actual or potential Claim as to which any indemnity provided for in this Article 12 or
Section 2.2.13.2(d) may apply, the Indemnitee shall give Contractor or Owner, as the case may be, Notice of such fact; provided, however, the failure to give such Notice will not relieve the indemnifying Party of its
obligations to indemnify the Indemnitee, except to the extent that the indemnifying Party is materially and adversely affected thereby. The indemnifying Party shall assume on behalf of the Indemnitee, and conduct with due diligence and in good
faith, the defense thereof with counsel reasonably satisfactory to the Indemnitee; provided, further, the Indemnitee shall have the right to be represented therein by counsel of its own selection and at its own expense (such expense
not to be subject to indemnification hereunder); provided, further, if the defendants in any such action include both the indemnifying Party and the Indemnitee, and if the Indemnitee has reasonably concluded that there may be legal
defenses available to it that are different from, additional to or inconsistent with those available to the indemnifying Party, then the Indemnitee will have the right to select separate counsel to participate in the defense of such action on its
own behalf. The indemnifying Party shall consult with each Indemnitee throughout the pendency of the Claim regarding the investigation, defense, settlement, compromise, trial, appeal or other 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 102 of 133

 
resolution thereof, and without the prior consent of each Indemnitee, the indemnifying Party shall not enter into any settlement of any Claim that would lead
to liability, constitute an admission of liability, dismiss a Claim without prejudice, or create any financial or other obligation on the part of any such Indemnitee for which such Indemnitee is not entitled to indemnification hereunder. 

12.6 Failure to Defend Action. If any Claim arises as to which any indemnity provided for in this Article 12 or
Section 2.2.13.2(d) may apply, and the indemnifying Party fails to assume the defense of such Claim with reasonable promptness after the receipt by the indemnifying Party of notification thereof, then the Indemnitee against which the
Claim is made, instituted or commenced may, at the indemnifying Party’s expense, contest, or settle, such Claim, providing the indemnifying party with reasonable advance notice of any settlement decision. All costs and expenses incurred by the
Indemnitee in connection with any such contest, settlement or payment may be deducted from any amounts due to the indemnifying Party under this Agreement, with all such costs in excess of the amount deducted to be reimbursed by the indemnifying
Party to the Indemnitee promptly following, but not later than 15 days following, the demand therefor. 
 12.7 No Limitation to
Workers’ Benefits. In any and all Claims against any Indemnitee by any employee of a Party or its Personnel, the indemnification obligations under Article 12 (except Sections 12.1(a) and 12.4(a)) shall not be
limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Party under workers’ or workmen’s compensation acts, disability benefit acts or other employee benefit acts. 

12.8 Limitation on Indemnification. In no event shall the indemnification provisions of this Article 12 or
Section 2.2.13.2(d) require an indemnifying Party to provide indemnification under this Agreement for any Claim, loss, liability or other damage incurred by an Indemnitee to the extent caused by the negligence or misconduct of such
Indemnitee or to the extent such indemnification is prohibited under Applicable Legal Requirements.

 ARTICLE 13 
 REMEDIES AND TERMINATION 
 13.1 Termination for Convenience. Owner shall have the right, in
its sole discretion, to terminate this Agreement, including portions of the Work to be performed by Contractor hereunder, in each case for its sole convenience (without necessity of giving a reason to Contractor), at any time upon 2 Business
Days’ prior written Notice thereof to Contractor. In the event of any termination for convenience by Owner pursuant to this Section 13.1 and compliance by Contractor of its obligations under Sections 13.1.2,
13.4.1 (as applicable) and 13.4.3 in connection with such termination, Contractor shall be relieved of its obligations and liability under this Agreement with respect to the portion of this Agreement or Work so terminated from and
after the date of such termination. 
 13.1.1 Termination Payment. If this Agreement is terminated under
Section 13.1, then, subject to Sections 13.1.1, 13.1.2, 13.4.1 (as applicable) and 13.4.3, as Contractor’s sole and exclusive remedy hereunder, (a) Contractor will be entitled to payment of
(i) the unpaid Time and Materials Costs incurred or Phase 2 Price Fixed Component earned through the effective date of termination, (ii) all cancellation charges necessarily incurred by Contractor in relation to its Subcontractors,
(iii) an amount equal to other reasonable termination-related actual costs necessarily incurred by Contractor, including its obligations under this Article 13, (iv) reasonably incurred actual costs of demobilization, and
(v) Sales Taxes properly paid by Contractor for which it has not been reimbursed (the “Termination Payment”). The Acceptable Letter of Credit provided to Owner pursuant to Section 5.2.7 shall be released by Owner on
or before the 5th day following the effective date of the termination (to include a termination under Section 13.5). Contractor shall calculate amounts due pursuant to this Section 13.1.1, which amounts will be subject to
audit by Owner. Notwithstanding a termination hereunder, the Parties shall remain liable to each other for liabilities that have accrued under other provisions of this Agreement prior to such termination, and provided, further, the
Parties shall remain obligated and liable for obligations under this Agreement that by their express terms survive termination. The Parties recognize, agree and acknowledge that Owner’s termination right hereunder is a permitted action under
this Agreement and not a breach hereof or a default hereunder. Payment of the Termination Payment (or any portion thereof) will be made by Owner within 30 days following an invoice therefor accompanied by reasonable documentation in support thereof.

 13.1.2 Termination Obligations. The following shall be obligations of Contractor in connection with any full or
partial termination of this Agreement: (a) Contractor’s execution and delivery of all documents and taking reasonable steps, including the assignment of Contractor’s contractual rights, as Owner may require, for the purpose of fully
vesting in Owner all right, title 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 104 of 133

 
and interest of Contractor in and to all Subcontracts which Owner elects to assume, warranties, guarantees, Work and other agreements pertaining to the Work
that Owner elects to assume; provided, however, such Work, upon transfer, will not be subject to Article 9, (b) Contractor’s execution and delivery (and using reasonable commercial efforts to cause Subcontractors
and Owner Suppliers to execute and deliver) to Owner of all waivers and releases, in form and substance reasonably acceptable to Owner, required to establish that the Project and the Project Site, and any and all interests, estates or improvements
related thereto, are free from any and all Liens arising out of or in connection with performance by Contractor, any Subcontractor or any Owner Supplier so terminated, but only to the extent that (i) Contractor (or, in the case of any Owner
Contract, an Owner Supplier) has been paid for such work in accordance with the terms of this Agreement or with respect to Owner Suppliers, funds to enable Contractor to make payments to such Owner Suppliers have been deposited into the Owner
Supplier Payment Account as required hereunder, and (ii) only with respect to the portion of the work so terminated, (c) Contractor’s prompt delivery to Owner of any other information reasonably requested by Owner, and
(d) Contractor’s removal from the Project Site of all of Contractor’s waste, debris, Personnel and property of Contractor (except as provided in Section 13.4.1). 
 13.1.3 Termination Due to Force Majeure. Either Party shall have the right to terminate this Agreement at any time by giving Notice
thereof to the other Party if the Work is suspended for more than 360 days due to Force Majeure, with such termination being handled under this Section 13.1. 
 13.2 Termination Upon Contractor Event of Default. If a Contractor Event of Default occurs, then Owner may, without prejudice to any other right or remedy Owner may have under this Agreement, at any time
terminate this Agreement, such termination becoming effective as provided in Section 13.4.3. For purposes hereof, a “Contractor Event of Default” shall occur if: 
  

	 	(a)	Contractor abandons or suspends progress of the Work for more than 10 days for any reason other than Force Majeure or as otherwise permitted by this Agreement;

  

	 	(b)	Contractor assigns or attempts to assign its rights or obligations under this Agreement or any part thereof to any Person without the prior written consent of Owner;

  

	 	(c)	a Contractor Act of Bankruptcy occurs; 

  

	 	(d)	Contractor does not perform any of its material obligations under this Agreement; 

  

	 	(e)	Contractor fails or refuses to comply with any Applicable Legal Requirements applicable to Contractor under this Agreement, which failure or refusal could result in a material
adverse effect on Owner, the Work or the Project; 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 105 of 133

	 	(f)	any representation or warranty made by Contractor herein or in any Application for Payment or other document submitted to Owner under this Agreement is false in any material respect
when made; 

  

	 	(g)	Contractor fails or refuses to pay any amount that is due to Owner under this Agreement within 30 days after receipt by Contractor of Notice from Owner stating that unless the
delinquent amount is paid within 30 days after this demand the failure will constitute a Contractor Event of Default; 

  

	 	(h)	Contractor does not obtain and maintain the insurance required of it pursuant to Section 2.9; provided, however, if Contractor’s failure to maintain
such insurance is caused by the bankruptcy of a carrier providing its insurance, without limiting Owner’s rights to procure insurance pursuant to Section 2.9, a Contractor Event of Default pursuant to this clause will not occur if
Contractor’s failure is rectified within 7 Business Days of such failure; or 

  

	 	(i)	Contractor fails or refuses or is unable at any time during the course of the Work, except in the event of Force Majeure event or during a suspension of the Work for reasons that
give Contractor the right under this Agreement to so suspend the Work, to provide or implement a Recovery Plan required hereunder to the reasonable satisfaction of Owner; 

 Notwithstanding anything in this Agreement to the contrary, the events described in this Section 13.2 will not constitute a
Contractor Event of Default unless and until: (i) Owner has given Notice to Contractor specifying with particularity the existence of such default which, unless cured (if a cure period applies), constitutes a Contractor Event of Default that
gives Owner a right to terminate its obligations to Contractor for cause under this Section 13.2, and (ii) in the case of Sections 13.2(a), 13.2(d), 13.2(e), 13.2(f), 13.2(g) or 13.2(i)
only, Contractor has failed to cure such default within 30 days after receipt of such Notice, or in the case such default cannot be cured within 30 days, has failed within 30 days to initiate and thereafter diligently and continuously pursue actions
reasonably likely to cure such default within an additional 90 days. 
 13.3 Termination for Agreed Circumstances. Owner has the
right, in its sole discretion, to terminate this Agreement or any portion hereof at any time by giving Notice thereof to Contractor upon the occurrence of any of the following events: 
  

	 	(a)	Final Completion does not occur within 180 days following the Target Final Completion Date; or 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 106 of 133

	 	(b)	Substantial Completion does not occur within 12 months following the Contractual Required Substantial Completion Date; or 

  

	 	(c)	Contractor is not obligated to pay amounts otherwise owed to Owner hereunder due to its limitation on liability set forth in Section 16.1 and the Project is more than
[180] days behind Schedule. 

 13.4 Consequences of Termination; Actions upon Termination. 
 13.4.1 Assumption and Succession. Upon any termination pursuant to this Article 13, in addition to any other rights or
remedies that Owner may have under this Agreement, Owner may at its option elect to: (a) assume responsibility for and take title to and possession of the Project and any or all work, Materials or Equipment remaining at the Project Site that
are part of the Work, Construction Aids and any and all other Materials or Equipment located outside the Project Site that are part of the Work, with suitable compensation therefor; provided, however, such Work, upon transfer, will not
be subject to Article 9, and (b) succeed to the interests of Contractor in any or all Subcontracts (including leases). Upon termination of this Agreement by Owner in accordance with Article 13, if requested by Owner,
Contractor shall (a) withdraw from the Project Site, and (b) as requested by Owner in writing, assign one or more of its Subcontracts to Owner or any designee of Owner; provided, however, such assignee assumes the obligations
of Contractor thereunder and Contractor is relieved of liability thereunder for work performed, services rendered and obligations incurred after the date of assumption of such subcontract by Owner, and (c) turn over to Owner any Submittals
prepared prior to such termination and any Materials, Equipment, and any other designs, purchase orders prepared or ordered prior to such termination, and any tools, schedules, computer files and drawings (in native or original format) that are part
of the Work, with suitable compensation therefor (to the extent not previously paid but subject to Section 13.4.2). Owner may employ any other Person (hereinafter, a “Replacement Contractor”) to finish the Work in accordance
with the terms of this Agreement by whatever method that Owner may deem expedient. In addition, Contractor shall not remove any Equipment, Materials or tools that (a) have been fabricated especially for or are unique to the Project,
(b) are incorporated in or are attached to, or are intended to be incorporated in or attached to, the Project, (c) constitute temporary or permanent scaffolding or supporting elements for the construction of the Project, or (d) the
removal of which could damage the Project or any portion thereof then constructed, or otherwise materially adversely affect or delay the construction, use or maintenance of the Project, with suitable compensation therefor (to the extent not
previously paid but subject to Section 13.4.2). Contractor shall not have any further responsibility therefor upon such termination. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 107 of 133

 13.4.2 Completion of the Work. In the event of any termination for a Contractor
Event of Default, Owner may, at its option and at its expense, finish the Work by whatever method Owner reasonably deems expedient, provided that, as Contractor’s sole liability on account of such termination, Contractor shall be liable
to Owner for the reasonable costs of cover and transitioning the Work to the Replacement Contractor. Owner shall be entitled to withhold payments which Contractor determines are due to it prior to the date of termination, along with other amounts
for which Contractor is entitled to compensation under Section 13.4.1, until completion of the Work and determination by Owner that Contractor is entitled to such payments. Any amounts not paid hereunder if ultimately due shall bear
interest at the Late Payment Rate. Owner may in its discretion employ the Replacement Contractor to finish the Work by whatever method or means Owner in its discretion may deem expeditious; provided, however, the balance of Work will
be completed utilizing reasonable methods of construction management and construction consistent, to the maximum feasible extent, with the Project Schedule and as otherwise provided herein. In the event that any termination of this Agreement by
Owner because of a Contractor Event of Default pursuant to Section 13.2 is later adjudicated to have been improper, then Contractor shall be entitled to recover such amounts as Contractor is entitled to under
Section 13.1. 
 13.4.3 Actions Upon Termination. Upon receipt of Notice from Owner of termination of this
Agreement pursuant to either Section 13.1, Section 13.2 or Section 13.3, Contractor shall: (a) cease performance of the Work to the extent directed by Owner in the Notice and complete necessary demobilization
in connection with such termination, (b) take all actions that Owner may direct, for the protection and preservation of the Work and the Project (in whatever stage of completion), (c) transition the administration of the Owner Contracts to
Owner, (d) enter into no further Subcontracts related to the Project or the Work, and (e) at Owner’s instruction, assign its rights under any or all Subcontracts to Owner or Owner’s designee. In addition, upon any such
termination of this Agreement, Contractor shall be relieved of its obligation for performance under any Subcontracts assigned to Owner or its designee for work performed, services rendered or materials or equipment supplied after the effective date
of such assumption. The effective date of any termination of this Agreement pursuant to this Article 13 shall be the date established in the Notice of such termination delivered by the Party exercising its termination right hereunder.

 13.5 Owner Monetary and Non Monetary Defaults. 
 13.5.1 Non-Payment. If Contractor has not received any undisputed payment due it hereunder within 10 days after Contractor has
provided Notice to Owner of its failure to make the specified payment when due and owing or if a Owner Act of Bankruptcy occurs, then Contractor may stop Work until such Owner default is cured, at which time Contractor shall 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 108 of 133

 
re-commence performance of the Work in a timely fashion. If Contractor has not received any undisputed payment within 30 days after the date such payment is
due or if a Owner Act of Bankruptcy continues for more than 30 days, then Contractor may terminate this Agreement upon providing Notice of termination to Owner. In the event of such termination, Contractor shall receive compensation in accordance
with Section 13.1.1 (together with any payment that has accrued but has not been paid to it under this Agreement as of the date of such termination) as its sole remedy and the exclusive damages resulting from such termination.

 13.5.2 Non-Monetary Default. If any Owner Event of Default (other than a payment default as described in
Section 13.5.1 above) occurs, then (a) to the extent such Owner Event of Default materially and adversely affects Contractor’s ability to achieve any of the Target Contract Dates, increases Contractor’s cost to perform the
Work or otherwise adversely affects the provisions of this Agreement, Contractor, if it so requests, shall be entitled, and Owner shall execute, a Change Order as provided in Section 10.3, (b) Contractor shall be entitled to any
other right or remedy permitted under this Agreement (other than termination if such Owner Event of Default can be fully cured by a Change Order issued in accordance with Article 10 and in compliance with Applicable Legal Requirements)
as a result of such Owner Event of Default, and (c) Contractor shall be entitled to suspend its performance of the Work, such suspension to become effective upon Owner’s receipt of Notice thereof from Contractor. “Owner Events of
Default” shall occur if: 
 (a) Owner fails or refuses to comply with any Applicable Legal Requirements under this
Contract, which failure or refusal results in a material adverse effect on Contractor; 
 (b) any representation or warranty
made by Owner herein or in any other document submitted to Contractor under this Agreement is false in any material respect when made; 
 (c) Owner fails to perform any of its material obligations under this Agreement; 
 (d) a
Owner Act of Bankruptcy occurs; 
 (e) Owner fails to maintain insurance required hereunder; 
 (f) Owner makes an assignment in violation of the provisions hereof; or 
 (g) the Owner Guaranty fails to be in full force and effect. 
  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 109 of 133

 Notwithstanding anything in this Agreement to the contrary, the events described in the
definition of an Owner Event of Default will not constitute a Owner Event of Default, unless and until: (i) Contractor has given Notice to Owner specifying with particularity the existence of such default that, unless corrected (if a cure
period applies), constitutes an Owner Event of Default, and (ii) in the case of Sections 13.5.2(a), (b), (c), or (h), such default has not been cured within 30 days after receipt of such Notice, or in the case
that such default cannot be cured within 30 days, Owner has not within 30 days initiated or caused to be initiated and thereafter diligently pursued actions reasonably likely to cure such default within an additional 90 days; provided,
however, if the event described in Section 13.5.2(h) occurs and Owner has not provided the reasonable evidence therein required within 10 days of Notice by Contractor, Contractor may suspend performance of the Work until such
evidence is provided or it has the right to terminate upon Owner’s failure to cure as hereinbefore provided. 
 13.6 Duty to Mitigate
Damages. Each Party shall have the duty to mitigate damages to it arising from any default hereunder by the other Party.

 ARTICLE 14

Damages. To the fullest extent permitted by Applicable Legal Requirements, Contractor’s overall cumulative liability for liquidated damages to Owner arising under Section 8.2 will in no event exceed an amount equal to * of the
Target Total Work Cost, and Owner releases Contractor from, and waives all right of recovery against Contractor for, any damages beyond such limit of liability for defaults specified in Section 8. 2.

anticipated profits or revenues; loss of opportunity; loss of productivity; loss of shop space; claims of customers; costs of obtaining or maintaining loans; or loss of goodwill). The foregoing limitation is not intended to limit a Party’s

payable by Contractor in connection with termination of this Agreement because of a Contractor Event of Default will not be considered “special, incidental, indirect or consequential” costs or damages under this

 ARTICLE 17 
 DISPUTE RESOLUTION 
 17.1 Dispute Resolution Between the Parties. 
 17.1.1 Cooperation. Owner and Contractor desire that this Agreement operate between them fairly and reasonably. If any disputes,
differences, or questions (collectively, “Disputes”) arise between the Parties in respect of this Agreement or the subject matter hereof, representatives of the Parties shall cooperate, in good faith, to attempt to amicably resolve
the Dispute. If any Party believes that such representatives will not be able to resolve the Dispute, such Party may invoke the further dispute resolution procedures of this Section 17.1 and of Section 17.2. 
 17.1.2 Management Discussions. If representatives of the Parties cannot resolve a Dispute within 15 days, each Party shall prepare
a written statement of its position and deliver it to the other Party within 10 days after the expiry of the initial 15 day period, and one or more senior officers from each Party shall meet in person within 15 days in an effort to resolve the
Dispute. If the senior officers of either Party determine at any time that the Dispute cannot be resolved without referral of the Dispute to an independent third party, such Party shall notify the other Party that it wants to submit the Dispute to
mediation or arbitration in accordance with Sections 17.1.3 or 17.2, respectively; provided, however, no Party shall seek arbitration of any Dispute until a period of at least 20 days has elapsed since the Dispute
was referred to such senior officers, without a resolution having been reached. The pendency of a Dispute shall not delay progress of the Work or relieve either Party from its duty to perform its obligations under this Agreement. 
 17.1.3 Voluntary Mediation. If a Dispute cannot be resolved by the Parties pursuant to Sections 17.1.1 or
17.1.2, the Parties shall endeavor to resolve such Dispute by mediation which, unless a Party objects to mediation by giving Notice to the other Party prior to commencement of the mediation, shall be a condition precedent to arbitration.
Unless the Parties mutually agree otherwise, mediation shall be in accordance with the then-current Construction Industry Mediation Rules of the American Arbitration Association. Requests for mediation shall be filed in writing with the other Party
and with the American Arbitration Association.

		 		 	Page 117 of 133

 17.2 Arbitration. 
 17.2.1 Rules and Arbitrators. All Disputes that cannot be resolved by the Parties pursuant to Section 17.1 shall be
exclusively and finally settled by self-administered arbitration with 3 arbitrators conducted in accordance with the then current Construction Industry Arbitration Rules of the American Arbitration Association or any successor thereto (the
“Rules”), except as modified herein. Each Party to the arbitration shall select one arbitrator and the 2 arbitrators selected by the Parties shall select a third arbitrator within 15 days. If the 2 arbitrators fail to reach
agreement on the third arbitrator within such time limit, either Party may initiate the selection of the third arbitrator by resort to the American Arbitration Association. In any proceeding conducted under this Section 17.2 by the
American Arbitration Association, (a) no discovery shall be allowed with respect to appointment of an arbitrator and limited discovery shall be allowed with respect to disqualification of an arbitrator, (b) the arbitration hearing may be
scheduled upon not less than 10 days prior written notice to the Parties and shall not exceed 3 days in length, (c) direct testimony shall be presented by the Parties solely through written submissions, and (d) the final decision shall be
rendered within 30 days of submission of the matter for arbitration. 
 17.2.2 Impartiality, Independence and
Qualifications of Arbitrators. Each Person serving as an arbitrator (including the arbitrators selected by each Party) shall be impartial and independent third parties, shall perform his or her duties with diligence and in good faith, and have
practiced law as a licensed attorney for at least 20 years and have substantial legal experience in connection with the design, construction and operation of fossil fuel-fired electric generating facilities. If a person with such expertise is not
reasonably available, then an arbitrator with at least 20 years experience in the design, construction and operation of equivalent heavy industry experience (e.g. refineries, chemical facilities, etc.) may be selected. Upon objection of a Party,
under the Rules, to the appointment or continued service of an arbitrator, the Parties shall attempt to reach agreement upon such disqualification and, in the absence of such agreement, shall submit the matter to arbitration in accordance with this
Section 17.2 for resolution. If a Party-appointed arbitrator is disqualified, his or her replacement shall be selected by the Party appointing the original arbitrator. If the third arbitrator is disqualified, his or her replacement shall
be selected in accordance with the procedure outlined in Section 17.2.1. 
 17.2.3 Costs and Discovery.
Subject to the remaining terms of this Agreement, each Party shall bear the cost of the arbitrator which it selects and the Parties shall equally bear all other costs of arbitration, including the cost of the third arbitrator. If the arbitrators
find that a frivolous claim has been pursued by a Party or a Party engages in egregious conduct, the arbitrators may award all (or any portion) of any expenses of arbitration incurred in connection with the Dispute (including attorney fees, charges,
disbursements, expenses of expert witnesses and fees of the arbitrators) to the Parties in such proportion as may be determined by the arbitrators. The arbitrators may permit and/or limit the scope of discovery as may be reasonable under the
circumstances. Time is of the essence in any Dispute, and the arbitrators shall be permitted to issue monetary sanctions against any Party if, upon a showing of good cause, such Party is unreasonably delaying the proceedings. Except as may be
determined by the arbitrators pursuant to the second sentence of this Article 17.2.3, costs incurred by Contractor in prosecuting a dispute during Phase 1 under this Article 17 do not constitute Time and Materials Costs.

		 		 	Page 118 of 133

 17.2.4 Limitations. No Party shall submit a Dispute to arbitration when
institution of legal or equitable proceedings based on such Dispute would be barred by the applicable statute of limitations. The arbitrators may not amend or modify this Agreement, enter an award for damages that are prohibited hereunder or limit
any of the remedies set forth in this Agreement. 
 17.2.5 Additional Relief. Nothing in this Article 17
will preclude any Party from taking (or requesting any judicial or other authority to order) any measure in aid of arbitration prior to the commencement of or during the arbitration proceedings for the preservation of its rights and interests.

 17.2.6 Venue and Timing. The arbitration shall take place in New Orleans, Louisiana, and shall be conducted in
English. The arbitrators shall render their award (the “Award”) within 180 days from submission of the Dispute to arbitration. The Award shall be final and binding on the Parties hereto and non-appealable and may be confirmed and
enforced in any court of competent jurisdiction, unless the Award is procured by corruption or fraud. Except as provided in this Section 17.2, each Party hereby excludes and waives irrevocably any rights or application or appeal to the
courts of any jurisdiction to the fullest extent permitted by Applicable Legal Requirements. The court may correct the Award before confirmation, if (a) there was manifest error in any mathematical calculation or manifest error in the
description of any Person, thing or property referred to in the Award, (b) the arbitrators exceeded their powers by including in the decision or award a matter not submitted to them and the decision or award may be corrected without affecting
the merits of the decision upon the matter submitted, and (c) the Award is imperfect in a matter of form, which can be corrected without affecting the substance of the Award. If an Award is vacated, the matter will be resubmitted for resolution
according to the terms of this Agreement. 
 17.2.7 Continued Performance. Unless otherwise agreed in writing,
Contractor shall continue to perform the Work and Owner shall continue to make payments, both in accordance with this Agreement, pending the resolution of any Dispute hereunder. 
 17.2.8 Consolidation. The Parties agree that if a third party (including an Owner Supplier or a Subcontractor) is substantially
involved in a common question of fact or law or whose presence is necessary if complete relief is to be afforded and/or inconsistent decisions are to be avoided, then, the Parties will use their respective reasonable efforts to consolidate such
third party into the dispute resolution process herein contained, making such accommodating adjustments as are fair and appropriate to accommodate additional parties; provided, however, such third party has consented to such inclusion
and agrees to be bound by the Award of the arbitrators.

		 		 	Page 119 of 133

 17.2.9 When Inapplicable. The provisions relating to mandatory arbitration will
not be applicable to a claim asserted in an action in court by a person who is under no obligation to arbitrate such claim with either of the Parties to this Agreement insofar as the Parties to this Agreement may desire to assert any rights of
indemnity or contribution with respect to the subject matter of such action. 
 17.2.10 Cross Examination. Testimony
may be admitted by sworn affidavit, provided, however, the opposing Party must be given the right to cross-examine any witness whose testimony is so admitted. 
 17.2.11 Survival. The provisions of this Article 17 will survive the expiration or earlier termination of this
Agreement.

 ARTICLE 18 
 CONFIDENTIALITY 
 18.1 Confidential Information. The Parties and Owner has a proprietary
interest in information that will be furnished pursuant to this Agreement. The Parties and Owner shall keep in confidence and will not disclose any such information which in good faith is proprietary and which is specifically designated in writing
as being proprietary (“Confidential Information”) without the prior written permission of the disclosing Person (the “Disclosing Party”) or use any such information for other than the purpose for which it is
supplied, except as provided herein. Information relating to commercial terms of this Agreement shall also be treated as Confidential Information; provided, however, that such obligation is not intended to restrict Owner from use of
the form of agreement. Each Party and Owner agrees that the other Party and Owner may disclose any Confidential Information to its or their consultants, representatives and to such other persons, including the Financing Parties and potential Owner
or affiliates, as may be necessary to perform its or their obligations under this Agreement or any document related to the Project or the Financing thereof to which it is a Party or, in the case of Owner, to develop, finance or sell an interest in
the Project or any entity owning an equity interest directly or indirectly in the Project. Each Party shall be responsible for requiring any third party (excluding such Party’s (or its Affiliates) officers, directors, employees and counsel who,
in each case, will be informed of the requirement to comply with the terms of this Section 18.1) to which it wishes to disclose Confidential Information to enter into a confidentiality agreement on substantially the terms of this
Article 18 or, in the case of Financing Parties, if a Party or Owner is unable to get any Financing Party to agree to such terms after expending a reasonable effort to do so, on reasonable terms and conditions that are customary for
confidentiality agreements for similarly situated parties receiving proprietary information comparable to the Confidential Information; provided, however, if a third party (a party other than Owner, or its Affiliates, officers,
directors, employees and counsel) has agreed in a writing provided to Contractor to maintain the confidentiality of Confidential Information in connection with the Project, such third party shall not be required to enter into another confidentiality
agreement pursuant to this Article 18. Each Party and Owner agrees with respect to Confidential Information, to hold the same confidential for the shorter of a period of 5 years from receipt or for a period of 3 years from the earlier to
occur of termination or Final Completion. The provisions of this Article 18 shall not apply 
  

	 	(a)	to information which the receiving Person (the “Receiving Party”) can substantiate: 

  

	 	(i)	was in the possession of the Receiving Party at the time it was initially furnished, without a breach of this provision; 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 121 of 133

	 	(ii)	is or becomes part of the public domain without a breach of this provision; 

  

	 	(iii)	is received from a third party who is, as far as reasonably can be determined, under no limitation or restriction regarding disclosure; or 

  

	 	(iv)	information the Disclosing Party authorizes the Receiving Party to describe. 

 Such information shall not be deemed to be within one of the foregoing exceptions if it is merely embraced by more general information available on a non-confidential basis to the Receiving Party; 
  

	 	(b)	to the extent that a Receiving Party is required to disclose Confidential Information pursuant to Applicable Legal Requirements (including in connection with a Financing), or uses
information in connection with any legal proceeding or Dispute under Article 17 hereof; provided, however, promptly upon a Receiving Party or any Owner, as applicable, becomes aware that Confidential Information may be
required to be disclosed pursuant to Applicable Legal Requirements, the Receiving Party or Owner gives notice to the other Party and, in consultation with the Disclosing Party, takes reasonable steps to make the Disclosing Party’s Confidential
Information subject to reasonably available procedures for maintaining its confidentiality; or 

  

	 	(c)	to any Record Documents or other Submittals related to the Project to the extent disclosure thereof is reasonably necessary in connection with the design, engineering, construction,
operation, maintenance, improvement, modification, expansion or other activity related to the Project; provided, however, Owner shall require the recipient of Confidential Information contained therein to maintain the confidentiality
of such Confidential Information on terms substantially similar to the terms of this Article 18 and to limit use of such Confidential Information to the Project. 

 18.2 Publicity. Contractor agrees that all public relation matters arising out of or in connection with the Work will be the sole responsibility
of Owner. Therefore, Contractor shall obtain Owner’s prior written approval of the text of any announcement, publication, technical report, article, photograph or any other media release, or general public communication concerning the Work that
specifically mentions Owner or any of its Affiliates or the Project or the Project Site or any of the Financing Parties which Contractor or its Subcontractors or vendors or any of their respective Affiliates wish to release for publication.
Contractor shall include in each Contractor Subcontract a provision requiring each Subcontractor to adhere 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 122 of 133

 
to the requirements of this Section 18.2. Owner shall obtain Contractor’s prior written approval of the text of any announcement,
publication, technical report, article, photograph or any other media release or general public communication concerning the Work that specifically mentions Contractor or any of its Affiliates which Owner wishes to release for publication.

 18.3 Prior Confidentiality Agreements. The provisions of this Article 18 supersede all prior agreements (including
confidentiality obligations under the Letter of Intent) between Contractor and Owner regarding the confidentiality of any information or documents regarding the Project or the matters described in this Agreement. Any such prior agreements between
the Parties or their respective predecessors or Affiliates shall have no force or affect on or after the Effective Date. 
 18.4
Injunctive Relief. The Parties agree that both injunctive relief and monetary damages, alone or in combination, are appropriate remedies for any breach of this Agreement by the other Party, its partners, parents, subsidiaries or affiliates, or
the employees, agents or consultants of any of them.

 ARTICLE 19 
 COST RECORDS 
 19.1 Records. Contractor shall maintain fiscal records, books and accounts
pertaining to the Project in accordance with generally accepted accounting principles consistently applied. 
 19.2 Inspection of Books,
Records and Audit Rights. Contractor shall keep and maintain full, complete and detailed records, books, accounts and invoices of all of its costs and expenses relating to any Application for Payment and any costs incurred or payments made by or
to it pursuant to this Agreement or in connection with the Work or Statement of Owner Supplier Costs. At all times during the progress of the Work and for a period of 2 years after the Final Completion Date, or, if the Final Completion Date does not
occur, for 2 years after the termination of this Agreement, Contractor shall afford Owner and its respective auditors and counsel, access at reasonable times to any of the above books and records relating to amounts paid to Contractor on the basis
of its costs or damages (including indemnifications) in order to inspect, copy and audit the same or to verify compliance by Contractor with all of the terms and conditions of this Agreement; provided, however, the right to inspect,
access, copy and/or audit Contractor’s books, records, invoices, and accounts shall not extend to agreed rates, agreed lump sum amounts, agreed allowances or to the internal composition of amounts (such as wage markups) expressed as a
percentage of other costs.

 ARTICLE 20 
 MISCELLANEOUS 
 20.1 Authorized Representatives. In order to secure effective cooperation and
to deal on a prompt and orderly basis with the various scheduling and administrative issues that may arise in connection with the rights and obligations of the Parties hereunder, each Party shall appoint its own authorized representative
(“Authorized Representative”) and notify the other Party in writing of such representative’s name, address, facsimile and telephone number within 10 days after the execution of this Agreement. Either Party may, at any time,
change the designation of its Authorized Representative; provided, however, such Party shall promptly notify the other Party in writing of such change. Each Party’s Authorized Representative shall be authorized to amend this
Agreement (including the execution of Change Orders) on behalf of the designating Party and agree upon procedures and provide such information as is necessary for coordinating the efforts of the Parties. 
 20.2 Assignment/Delegation. 
 20.2.1 Assignment/Delegation by Contractor. Except as provided in Sections 20.2.2 or 20.17, it is expressly understood and agreed that this Agreement is personal to each of the Parties hereto, and that neither
Party shall have the right, power or authority to assign or delegate its rights or obligations under this Agreement or any portion thereof, either voluntarily or involuntarily, or by operation of law without the written consent of the other Party,
except that a Party’s rights to payments hereunder may be assigned without the other Party’s consent and except as provided in Section 20.17(a)(iii). Notwithstanding the above, Contractor may have portions of the Work performed
by its Affiliates or their Personnel, in which event Contractor shall be responsible for such portions of the Work, such portions of the Work shall be deemed to have been performed by Contractor for all purposes under this Agreement, and Owner will
look solely to Contractor in connection with such portions of the Work. 
 20.2.2 Assignment/Delegation by Owner. 
 20.2.2.1 Affiliates. Owner reserves the right, in its sole discretion and without the prior consent of Contractor, to assign all or
any of its rights and/or to delegate all or any of its obligations under this Agreement to one or more of its Affiliates. Owner shall give Contractor Notice of such assignment and/or delegation. Upon its receipt of Notice of a delegation or
assignment of Owner’s obligations under this Agreement, Contractor shall be deemed to have released Owner from all of the obligations so delegated or assigned so long as the assignee/delegate of such obligations assumes the obligations so
assigned or delegated and each Owner either reissues or affirms the continued effectiveness of its Owner 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 125 of 133

 
Guaranty. If Owner or Contractor so requests, then Contractor or Owner (as the case may be) shall, without delay or conditions, execute a written release
that confirms Owner’s release from such obligations or such assignee’s/ delegate’s assumption of such obligations (as the case may be). 
 20.2.2.2 Third Parties. Owner may assign any or all of its rights and/or delegate any or all of its obligations under this Agreement to any Person other than an Affiliate; provided, however, Owner
will not be relieved of its obligations hereunder so assigned or delegated, unless Contractor consents to such assignment or delegation; provided, further, such consent will not be unreasonably withheld, unreasonably conditioned or
unreasonably delayed. If, upon its request for such consent, Contractor has concerns that may lead to its withholding such consent, then Contractor shall promptly identify such concerns to Owner, meet and in good faith discuss with Owner appropriate
steps that may be taken to address and resolve such concerns so as to allow for such consent to be granted. If Contractor consents to such assignment, Contractor shall be deemed to have released Owner from all of the obligations so delegated or
assigned so long as the assignee/delegate of such obligations assumes the obligation so assigned or delegated; provided, that each Owner either reissues or affirms the continued effectiveness of its Owner Guaranty. If Contractor has consented
to the delegation of Owner’s obligations as provided above, then, if Owner so requests, Contractor shall execute documentation evidencing such consent and releasing Owner from such delegated obligations. Contractor shall be entitled to reject
any such assignment and/or delegation where such assignment and /or delegation would be to one of Contractor’s competitors in the engineering and construction business. 
 20.2.3 Successors and Assigns. Subject to Sections 20.3.1 and 20.2.2, the provisions of this Agreement shall

		 		 	Page 129 of 133

 20.17 Cooperation with Financing Efforts. Contractor shall use reasonable efforts to cooperate
with Owner in connection with their respective efforts to obtain and maintain Financing; provided, however, Owner agrees to act as a single point of contact between the Financing Parties of the respective Owner and Contractor to the
maximum extent possible. Without limiting the generality of the foregoing, Contractor: 
  

	 	(a)	shall execute such documents as reasonably requested in connection with obtaining and maintaining Financing whereby Contractor (i) certifies to the Financing Parties that this
Agreement is in full force and effect and has not been modified and that there are no defaults under this Agreement (except, in each case, as specifically stated in such certification), (ii) represents and warrants to the Financing Parties that
this Agreement is enforceable against Contractor, (iii) consents to the collateral assignment of this Agreement to the Financing Parties as security for the debt relating to the Financing, (iv) agrees to give the Financing Parties Notice
of a Owner Event of Default contemporaneously with the Notices provided to Owner and an opportunity to cure such defaults, (v) clarifies provisions of this Agreement as reasonably requested by the Financing Parties, and (vii) agrees to
cooperate with Owner in the negotiation of such amendments to this Agreement as the Financing Parties may reasonably request; 

  

	 	(b)	at Owner’s reasonable request, shall attend and participate in presentations to potential Financing Parties; 

  

	 	(c)	hereby authorizes Owner and any Owner to (i) provide this Agreement to potential Financing Parties and equity participants (subject to Article 18), and
(ii) include a description of the material provisions of this Agreement in any offering circular required for the Financing and/or, if the Financing must be registered in accordance with Applicable Legal Requirements, that Owner may, after
consultation with Contractor, file this Agreement as an exhibit to such registration statement (which filing will include requests for confidentiality with respect to pricing and other key commercial terms); 

  

	 	(d)	at Owner’s request, shall reasonably cooperate with the Financing Engineer and any rating agencies or other credit enhancement entities associated with a Financing;

  

	 	(e)	at Owner’s request, shall reasonably cooperate in connection with tax-exempt financing or any financing or other arrangements effected to reduce Taxes on the Project or the
Work; and 

  

	 	(f)	Contractor shall provide Owner with legal opinions of in-house counsel to Contractor regarding the execution, delivery and validity of this Agreement and the status of Contractor as
Owner will reasonably request in connection with obtaining and maintaining the Financing.

		 		 	Page 130 of 133

 20.18 Financing Engineer. Contractor acknowledges that the Financing Engineer will be engaged for
the purpose of providing to the Financing Parties a neutral, third party overview of the Work. The Financing Engineer will be a recognized engineering and consulting firm selected by the Financing Parties and bound by confidentiality obligations
substantially similar to those contained in Article 18. The Financing Engineer is expected to provide the Financing Parties with independent opinions with respect to: (a) the status of the Work, (b) the performance of the Work
and associated Equipment, (c) Contractor’s Performance Test procedures, (d) Contractor’s quality assurance program for the Work and major components thereof, (e) the results of the Performance Tests, and
(f) Applications for Payment and Change Orders submitted by Contractor. The Financing Engineer may attend all monthly meetings. Notwithstanding anything else to the contrary contained herein, the Financing Engineer will have no right to direct
Contractor or any portion of the Work or to make any changes to the Work. 
 20.19 Owner’s Engineer. Owner’s Engineer shall
act on Owner’s behalf, in relation to various Project-related matters, including the review of contract documents, attending design and progress meeting, carrying out inspections and the review and approval of test results and most particularly
all Performance Test results. 
 20.20 Review Committee. The Parties recognize that the most efficient and cost effective
implementation of the Work will necessitate continual monitoring of the Labor Plan and other strategic decisions that may have a material effect on the Total Installed Cost or Project Schedule that the Parties agree to have considered by the Review
Committee. Because the nature of labor compensation decisions is expected to require the balancing of interests and tradeoffs among project objectives, each Party will select 2 representatives to comprise a committee (the “Review
Committee”) to consider adjustments to the Labor Plan and other Project execution strategies. The initial members of this Review Committee are to be appointed within 30 days of the Effective Date. Each Party may change its representatives
on Notice to the other Party. Each Party shall ensure that its members on the Review Committee act reasonably at all times. The Review Committee will meet on an as-needed basis, but no less frequently than quarterly. With respect to each issue
considered by the Review Committee, Contractor and Owner, as appropriate, shall provide adequate materials and information sufficient to allow a reasonable basis on which decisions can be made. The Review Committee will meet promptly and work
cooperatively to adopt recommendations that support achievement of the Targets at the lowest Total Installed Cost, except as they otherwise unanimously agree. The Review Committee shall appoint one of its members to provide adequate notice of
meetings to the other members and to keep and distribute accurate minutes of its meetings. The Owner Project Manager and Contractor’s Construction Manager may be invited to attend meetings of the Review Committee but will not have any voting
rights. At such time as Contractor believes that the level of compensation being paid to Craft Labor with respect to a particular 

  

					
		 	Red River Environmental Products EPC Agreement	 	
		 		 	Page 131 of 133

 
Craft Labor Cost Component is or will, in the foreseeable future, not be sufficient to maintain existing Craft Labor or attract additional needed Craft
Labor, in each case in a specific Craft Labor Category, for the construction of the Project to support the Project Schedule, Contractor will give Notice to Owner and the Parties, acting through their representatives on the Review Committee, shall
take the following actions: 
 (a) Contractor will provide a reasonably detailed labor analysis, supported by a reasonable
level of factual compensation information, with respect to the specific Craft Labor Category(ies) as to which Contractor believes compensation adjustments are necessary. Such analysis shall include (i) Contractor’s recommended changes to
the level of Craft Labor Cost Component to be offered to such Craft Labor; (ii) a direct comparison with the then existing level of Craft Labor Cost Component being paid to the same Craft Labor Category(ies) at the Key Benchmark Projects and
the Other Benchmark Projects, to the extent such information is available; (iii) a forecast as the projected impact on the Total Work Cost of the Project that would result from Contractor’s recommended changes and (iv) an analysis of
any reasonably cost effective alternative to achieve the same goal; 
 (b) the members of the Review Committee shall consult
with each other in good faith and attempt to reach a unanimous decision as to the increased level of Craft Labor Cost Component (or alternative) to be offered to Craft Labor within such Craft Labor Category(ies) and as to when any changes should be
implemented; 
 (c) if the members of the Review Committee are not able to reach a unanimous decision, then Contractor may
implement its recommended changes, provided, that the level of the Craft Labor Cost Component to be offered to Craft Labor within the Craft Labor Category in question is no higher than         
percent (        %) in excess of (i) the highest level of Craft Labor Cost Component then being paid to Craft Labor within such Craft Labor Category working on Key Benchmark Projects; or
(ii) the average level of Craft Labor Cost Component then being paid to craft labor within such Craft Labor Category working on [Other Benchmark Projects], whichever is the greater between (i) and (ii). 
 (d) If such recommended changes would cause the level of the Craft Labor Cost Component for a specific Craft Labor Category to be higher
than permitted in clause (c) above, then, either the Review Committee must unanimously agree to make such change or either Party may refer the matter for decision by the senior officers of the Parties. Each Party shall, through its nominated
senior officer, prepare a written statement of its position and deliver it to the other Party within 10 days after referral of the matter to the senior officers. The nominated senior officers from each Party shall meet in person within 15 days after
the exchange of such written statements in an effort to resolve the matter.

the time of grant, a Form S-8 Registration Statement under the Securities Act (“Form S-8”) is not available to register either the offer or the sale of the Company’s securities to such Consultant because of the nature of the services
that the Consultant is providing to the Company, or because 

  

 6. 

 
the Consultant is not a natural person, or as otherwise provided by the rules governing the use of Form S-8, unless the Company determines both (i) that
such grant (A) shall be registered in another manner under the Securities Act (e.g., on a Form S-3 Registration Statement) or (B) does not require registration under the Securities Act in order to comply with the requirements of the
Securities Act, if applicable, and (ii) that such grant complies with the securities laws of all other relevant jurisdictions. 
 (ii) Form S-8 generally is available to consultants and advisors only if (i) they are natural persons; (ii) they provide bona fide services to the issuer, its parents, its majority-owned subsidiaries; and (iii) the
services are not in connection with the offer or sale of securities in a capital-raising transaction, and do not directly or indirectly promote or maintain a market for the issuer’s securities. 
  

	6.	OPTION PROVISIONS. 

 Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and,
if certificates are issued, a separate certificate or certificates will be issued for shares of Common Stock purchased on exercise of each type of Option. The provisions of separate Options need not be identical, but each Option shall include
(through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: 
 (a) Term. Subject to the provisions of subsection 5(b) regarding Ten Percent Shareholders, no Incentive Stock Option shall be exercisable after the expiration of ten (10) years from the date it was granted. 
 (b) Exercise Price of an Incentive Stock Option. Subject to the provisions of subsection 5(b) regarding Ten Percent Shareholders, the exercise
price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Incentive Stock
Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of
the Code. 
 (c) Exercise Price of a Nonstatutory Stock Option. The exercise price of each Nonstatutory Stock Option shall be not less
than eighty-five percent (85%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, a Nonstatutory Stock Option may be granted with an exercise price lower than
that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code. 
 (d) Consideration. The purchase price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes
and regulations, either (i) in cash at the time the Option is exercised or (ii) at the discretion of the Board at the time of the 

  

 7. 

 
grant of the Option (or subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the Company of other Common Stock,
(2) according to a deferred payment or other similar arrangement with the Optionee or (3) in any other form of legal consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option, the purchase
price of Common Stock acquired pursuant to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held
for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). At any time that the Company is incorporated in Delaware, payment of the Common Stock’s
“par value,” as defined in the Delaware General Corporation Law, shall not be made by deferred payment. 
 In the case of any deferred payment
arrangement, interest shall be compounded at least annually and shall be charged at a market rate of interest necessary to avoid a change to earnings for financial accounting purposes. 
 (e) Transferability of an Incentive Stock Option. An Incentive Stock Option shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Optionee only by the Optionee. Notwithstanding the foregoing, the Optionee may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Option. 
 (f) Transferability of a
Nonstatutory Stock Option. A Nonstatutory Stock Option shall be transferable to the extent provided in the Option Agreement. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory Stock Option shall not be
transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionee only by the Optionee. Notwithstanding the foregoing, the Optionee may, by delivering written notice to the Company,
in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Option. 
 (g) Vesting Generally. The total number of shares of Common Stock subject to an Option may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The
Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options may vary.
The provisions of this subsection 6(g) are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised. 
 (h) Termination of Continuous Service. In the event an Optionee’s Continuous Service terminates (other than upon the Optionee’s death or Disability), the Optionee may exercise his or her Option (to
the extent that the Optionee was entitled to exercise such Option as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionee’s
Continuous Service (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionee does not exercise his or her
Option within the time specified in the Option Agreement, the Option shall terminate. 
  

 8. 

 (i) Extension of Termination Date. An Optionee’s Option Agreement may also provide that if
the exercise of the Option following the termination of the Optionee’s Continuous Service (other than upon the Optionee’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would
violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in subsection 6(a) or (ii) the expiration of a period of three
(3) months after the termination of the Optionee’s Continuous Service during which the exercise of the Option would not be in violation of such registration requirements. 
 (j) Disability of Optionee. In the event that an Optionee’s Continuous Service terminates as a result of the Optionee’s Disability, the
Optionee may exercise his or her Option (to the extent that the Optionee was entitled to exercise such Option as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months
following such termination (or such longer or shorter period specified in the Option Agreement) or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionee does not exercise his or
her Option within the time specified herein, the Option shall terminate. 
 (k) Death of Optionee. In the event (i) an
Optionee’s Continuous Service terminates as a result of the Optionee’s death or (ii) the Optionee dies within the period (if any) specified in the Option Agreement after the termination of the Optionee’s Continuous Service for a
reason other than death, then the Option may be exercised (to the extent the Optionee was entitled to exercise such Option as of the date of death) by the Optionee’s estate, by a person who acquired the right to exercise the Option by bequest
or inheritance or by a person designated to exercise the Option upon the Optionee’s death pursuant to subsection 6(e) or 6(f), but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of
death (or such longer or shorter period specified in the Option Agreement) or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the
Option shall terminate. 
 (l) Early Exercise. The Option may, but need not, include a provision whereby the Optionee may elect at any
time before the Optionee’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Any unvested shares of Common Stock so purchased
may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. 
  

	7.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

 (a) Stock Bonus Awards. Each stock bonus agreement shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The terms and conditions of stock bonus agreements may change from time to time, and the terms and conditions of separate stock bonus agreements need not be identical, but each stock bonus agreement
shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 
 (i) Consideration. A stock bonus may be awarded in consideration for past services actually rendered to the Company or an Affiliate for its benefit. 
  

 9. 

 (ii) Vesting. Shares of Common Stock awarded under the stock bonus agreement may, but need not, be
subject to a share repurchase option in favor of the Company in accordance with a vesting schedule to be determined by the Board. 
 (iii)
Termination of Participant’s Continuous Service. In the event a Participant’s Continuous Service terminates, the Company may reacquire any or all of the shares of Common Stock held by the Participant which have not vested as of the
date of termination under the terms of the stock bonus agreement. 
 (iv) Transferability. Rights to acquire shares of Common Stock
under the stock bonus agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the stock bonus agreement, as the Board shall determine in its discretion, so long as Common Stock awarded under the
stock bonus agreement remains subject to the terms of the stock bonus agreement. 
 (b) Restricted Stock Awards. Each restricted stock
purchase agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of the restricted stock purchase agreements may change from time to time, and the terms and conditions
of separate restricted stock purchase agreements need not be identical, but each restricted stock purchase agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the
following provisions: 
 (i) Purchase Price. The purchase price under each restricted stock purchase agreement shall be such amount as
the Board shall determine and designate in such restricted stock purchase agreement. The purchase price shall not be less than eighty-five percent (85%) of the Common Stock’s Fair Market Value on the date such award is made or at the time
the purchase is consummated. 
 (ii) Consideration. The purchase price of Common Stock acquired pursuant to the restricted stock
purchase agreement shall be paid either: (i) in cash at the time of purchase; (ii) at the discretion of the Board, according to a deferred payment or other similar arrangement with the Participant; or (iii) in any other form of legal
consideration that may be acceptable to the Board in its discretion; provided, however, that at any time that the Company is incorporated in Delaware, then payment of the Common Stock’s “par value,” as defined in the Delaware General
Corporation Law, shall not be made by deferred payment. 
 (iii) Vesting. Shares of Common Stock acquired under the restricted stock
purchase agreement may, but need not, be subject to a share repurchase option in favor of the Company in accordance with a vesting schedule to be determined by the Board. 
  

 10. 

 (iv) Termination of Participant’s Continuous Service. In the event a Participant’s
Continuous Service terminates, the Company may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant which have not vested as of the date of termination under the terms of the restricted stock purchase
agreement. 
 (v) Transferability. Rights to acquire shares of Common Stock under the restricted stock purchase agreement shall be
transferable by the Participant only upon such terms and conditions as are set forth in the restricted stock purchase agreement, as the Board shall determine in its discretion, so long as Common Stock awarded under the restricted stock purchase
agreement remains subject to the terms of the restricted stock purchase agreement. 
  

	8.	COVENANTS OF THE COMPANY. 

 (a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of Common
Stock required to satisfy such Stock Awards. 
 (b) Securities Law Compliance. The Company shall seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this undertaking shall not require
the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such
Stock Awards unless and until such authority is obtained. 
  

	9.	USE OF PROCEEDS FROM STOCK. 

 Proceeds from the sale of Common Stock pursuant to Stock Awards shall constitute general funds of the Company. 
  

	10.	MISCELLANEOUS. 

 (a) Acceleration
of Exercisability and Vesting. The Board shall have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding
the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. 
 (b)
Shareholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Stock Award unless and until such Participant has satisfied all
requirements for exercise of the Stock Award pursuant to its terms. 
 (c) No Employment or other Service Rights. Nothing in the Plan
or any instrument executed or Stock Award granted pursuant thereto shall confer upon any Participant any right to 

  

 11. 

 
continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or
an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or
(iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 
 (d) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common
Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or
portions thereof which exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 
 (e) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the
Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or
she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring
Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the
Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of
counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of
the Common Stock. 
 (f) Withholding Obligations. To the extent provided by the terms of a Stock Award Agreement, the Participant may
satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of Common Stock under a Stock Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid
to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a
result of the exercise or acquisition of Common Stock under the Stock Award, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to
the Company owned and unencumbered shares of Common Stock. 
  

 12. 

	11.	ADJUSTMENTS UPON CHANGES IN STOCK. 

 (a) Capitalization Adjustments. If any change is made in the Common Stock subject to the Plan, or subject to any Stock Award, without the receipt
of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares,
change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of securities subject to the Plan pursuant to subsection 4(a)
and the maximum number of securities subject to award to any person pursuant to subsection 5(c), and the outstanding Stock Awards will be appropriately adjusted in the class(es) and number of securities and price per share of Common Stock subject to
such outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction “without
receipt of consideration” by the Company.) 
 (b) Corporate Transaction. The following provisions shall apply to Stock Awards in
the event of a Corporate Transaction unless otherwise provided in the instrument evidencing the Stock Award or any other written agreement between the Company or any Affiliate and the holder of the Stock Award or unless otherwise expressly provided
by the Board at the time of grant of a Stock Award. Except as otherwise stated in the Stock Award Agreement, in the event of a Corporate Transaction, then, notwithstanding any other provision of the Plan, the Board shall take one or more of the
following actions with respect to Stock Awards, contingent upon the closing or completion of the Corporate Transaction: 
 (i) arrange
for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to,
an award to acquire the same consideration paid to the stockholders of the Company pursuant to the Corporate Transaction); 
 (ii)
arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring
corporation’s parent company); 
 (iii) accelerate the vesting of the Stock Award (and, if applicable, the time at which the
Stock Award may be exercised) to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is fifteen (15) days prior to the effective date
of the Corporate Transaction), with such Stock Award terminating if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction; 
 (iv) arrange for the lapse of any reacquisition or repurchase rights held by the Company with respect to the Stock Award; and 
  

 13. 

 (v) cancel or arrange for the cancellation of the Stock Award, to the extent not vested or not
exercised prior to the effective time of the Corporate Transaction, in exchange for such cash consideration as the Board, in its sole discretion, may consider appropriate. 
 The Board need not take the same action with respect to all Stock Awards or with respect to all Participants. 
 (c) Change of Control. 
 (i) With respect to any Stock Award granted on or after the Effective Date, the Stock Award
may be subject to additional acceleration of vesting and exercisability upon or after a Change of Control (as defined below) as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written plan or any
other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration shall occur. 
 (ii) This Section 11(c)(ii) shall be effective with respect to Stock Awards granted before the Effective Date. In the event of a Change of Control (as defined below), the Company shall, at least fifteen
(15) days prior to such Change of Control, notify in writing all Optionees of such Change of Control and of the acceleration of the vesting of the outstanding Stock Awards held by such Optionees. Such notice shall give such Optionees the right
to exercise their Stock Awards immediately prior to the Change of Control. Such acceleration of vesting and right to exercise shall be conditioned upon the consummation of the transaction constituting the Change of Control. In the event any
surviving or acquiring corporation, pursuant to Section 11(b) above, assumes any Stock Awards outstanding under the Plan or substitutes similar stock awards for those outstanding under the Plan, then, to the extent not exercised prior to the
Change of Control, the vesting of such assumed or substituted Stock Awards shall be fully accelerated at the time of the Change of Control and shall remain fully vested at all times thereafter. 
 (iii) For purposes of the Plan, a “Change of Control” shall mean any one or more of the following events: 
 (1) a sale of sixty percent (60%) or more of the assets of the Company or the Subsidiary; 
 (2) a merger or consolidation involving the Company or the Subsidiary in which the Company or the Subsidiary is not the surviving corporation and
the shareholders of the Company immediately prior to the completion of such transaction hold, directly or indirectly, less than fifty percent (50%) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange
Act, or comparable successor rules) of the securities of the surviving corporation (excluding any shareholders who possessed a beneficial ownership interest in the surviving corporation prior to the completion of such transaction); 
 (3) a reverse merger involving the Company or the Subsidiary in which the Company or the Subsidiary, as the case may be, is the surviving
corporation but the shares of Common Stock of the Company or the Subsidiary outstanding immediately preceding 

  

 14. 

 
the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, and the shareholders of the
Company immediately prior to the completion of such transaction hold, directly or indirectly, less than fifty percent (50%) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rules) of the surviving entity or, if more than one entity survives the transaction, the controlling entity; 
 (4) an
acquisition by any person, entity or group within the meaning of Section 13(d) or 14(d) of the Exchange Act or any comparable successor provisions (excluding any employee benefit plan, or related trust, sponsored or maintained by the Company or
an Affiliate of the Company) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable successor rules) of securities of the Company or the Subsidiary representing at least fifty percent
(50%) of the combined voting power entitled to vote in the election of directors; or, 
 (5) in the event that the individuals
who, as of the effective date of the Plan, are members of the Board (the “Incumbent Board”), cease for any reason to constitute at least fifty percent (50%) of the Board. (If the election or nomination for election by the
Company’s shareholders, of any new member of the Board is approved by a vote of at least fifty percent (50%) of the Incumbent Board, such new member of the Board shall be considered as a member of the Incumbent Board.) 
 Notwithstanding the foregoing, for the purposes of this Plan and with respect to any and all clauses of this Section of the Plan, an initial public offering of the
securities of the Company (an “IPO”) or any transactions or events constituting part of an IPO shall not be deemed to constitute or in any way effect a Change of Control. 
  

	12.	AMENDMENT OF THE PLAN AND STOCK AWARDS. 

 (a) Amendment of Plan. The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 11 relating to
adjustments upon changes in Common Stock, no amendment shall be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3 or
any Nasdaq or securities exchange listing requirements. 
 (b) Shareholder Approval. The Board may, in its sole discretion, submit any
other amendment to the Plan for shareholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of compensation paid to certain executive officers. 
 (c)
Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions
of the Code and the regulations promulgated thereunder relating to Incentive Stock Options and/or to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith. 
  

 15. 

 (d) No Impairment of Rights. Rights under any Stock Award granted before amendment of the Plan
shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 
 (e) Amendment of Stock Awards. The Board at any time, and from time to time, may amend the terms of any one or more Stock Awards (including, but not limited to, the extension of the post-termination exercise
period of an Option); provided, however, that the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing.

  

	13.	TERMINATION OR SUSPENSION OF THE PLAN. 

 (a) Plan Term. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on the day before the
tenth (10th) anniversary of the date the Plan is adopted by the Board or approved by the shareholders of the Company, whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated.

 (b) No Impairment of Rights. Suspension or termination of the Plan shall not impair rights and obligations under any Stock Award
granted while the Plan is in effect except with the written consent of the Participant. 
  

	14.	EFFECTIVE DATE OF PLAN. 

 The Plan shall become effective as of the effective date of the initial public offering of the Common Stock, but no Stock Award shall be exercised (or, in
the case of a stock bonus, shall be granted) unless and until the Plan has been approved by the shareholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.

  

	15.	CHOICE OF LAW. 

 The law of the State of Washington shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such state’s conflict of laws rules.
