|-- | ------------------

5.1 Assignment of Borrowed
Employees. Each of Contractor and Owner shall assign certain of its employees (the Borrowed Employees) to the other Party to perform certain job duties required for completion of the entire Project, including the job duties
identified as Shared Services in the Staffing Plan and the Communication and Management Protocol and the job duties necessary to complete portions of the CM ISBL Work (collectively, the Assigned Job Duties). By assigning a
Borrowed Employee, each Party represents that it has completed the Screening Measures (as defined below) with respect to such Borrowed Employee and that such Screening Measures did not reveal any information that adversely affects such Borrowed
Employees suitability for employment by such Party. As used in this Section, the term Screening Measures means, with respect to either Party, such screening and eligibility measures as required by such Partys generally
applicable human resources policies and procedures (the HR Policies) and applicable Law. Each Party shall maintain all records with respect to each of its Borrowed Employees as required of an employer by applicable Law. At all
times that a person is serving as a Borrowed Employee, such Borrowed Employee shall remain an employee of the Party supplying such Borrowed Employee subject to all of its HR Policies. Promptly after execution of this Agreement, each Party shall
designate in writing a liaison to be responsible for addressing performance, conduct, and compliance issues (HR Issues) relating to the Borrowed Employees. Each Party may change its designated liaison from time to time upon ten
(10) Days prior written notice to the other Party.

5.2 Qualifications. Each Party shall provide curriculum vitae for each
person such Party proposes to be a Borrowed Employee, which curriculum vitae shall include a description of the role of such person in his or her recent projects. Each Party shall permit the other Party the opportunity to interview each such person.
Each Party covenants that its Borrowed Employees shall have such credentials represented in writing by it to the other Party. Contractor shall reassign any such Borrowed Employee to a project other than the Project at Owners request exercised
in its reasonable discretion. Contractor shall not cease providing Owner with the services of any of its Borrowed Employees without the prior written approval of Owner, provided that Contractor may cease providing Owner with the services of a
Borrowed Employee without the prior approval of the Owner (a) if such Borrowed Employee dies, resigns, transfers in accordance with the HR Policies, goes on leave of absence in accordance with the HR Policies (in which case Contractor shall
provide Owner notice of all relevant dates regarding such leave of absence), or is terminated for cause, as defined in the HR Policies, (b) if such Borrowed Employee is not expected (by Owner) to perform any services in connection with, or
otherwise relating to, the start-up of the Facility (including any scheduling or planning), upon the Mechanical Completion Date or such later date upon which the Parties may mutually agree or (c) if such Borrowed Employee is expected (by Owner)
to perform services in connection with, or otherwise relating to, the start-up of the Facility (including any scheduling or planning), upon the Final Completion Date. If Contractor ceases to provide a Borrowed Employee as permitted herein,
Contractor shall promptly replace such Borrowed Employee with another Borrowed Employee meeting the requirements hereof. Owner may reassign any of its Borrowed Employees.

5.3 Assigned Job Duties. Each Party shall determine the procedures to be followed by the Borrowed
Employees assigned to such Party with respect to their Assigned Job Duties; provided, however, that such Party shall not direct such Borrowed Employees to perform any duties other than the Assigned Job Duties or to perform the Assigned Job Duties in
a manner that would violate any of the other Partys HR Policies known to such Party. Each Party represents to the other Party that nothing in its HR Policies prevent any of its Borrowed Employees from performing his or her Assigned Job Duties.
The Borrowed Employees assigned to each Party shall be advised by such Party of, and the assigning Party shall instruct such Borrowed Employees to comply with, all applicable office and field rules, regulations and safety procedures. To the extent
permitted by applicable Law, each Party assigning Borrowed Employees shall provide the other Party with such information pertaining to such Borrowed Employees in connection with rendering the Assigned Job Duties as the other Party may request and
which is reasonably necessary to the other Partys direction and oversight of such Borrowed Employees and the performance of the Assigned Job Duties. Each Party shall require each of its Borrowed Employees to obtain and maintain all licenses
(including professional engineering licenses) and work permits, if any, required in connection with his or her performance of the Assigned Job Duties.

5.4 Responsibility for Work. Each Party shall be solely responsible for the effectiveness or technical, economic or environmental feasibility of any method, technique, or process implemented by such Party or
third parties resulting from any Borrowed Employee furnished to it under this Section. Accordingly, neither Party assigning Borrowed Employees shall have any liability to the other Party for loss or damage arising out of or resulting from the
performance by such Borrowed Employees of the Assigned Job Duties, including loss of or damage to property of the other Party, and the other Party hereby releases and agrees to indemnify, hold harmless and defend the Party assigning Borrowed
Employees and each such Borrowed Employee from and against any and all claims, demands, losses, damages, costs, liabilities and expenses (including reasonable attorneys fees) for injuries to persons (including death) and for damage to
property, including property of the other Party or others, arising out of the performance by such Borrowed Employee of his or her Assigned Job Duties, provided that such Borrowed Employee had the credentials represented in writing by the Party
assigning Borrowed Employees to the other Party.

Employee, the Party assigning such Borrowed Employee and such Borrowed Employee shall act as an independent contractor and not as an agent or employee of the other Party. Neither Party intends to create a co-employment relationship for the Borrowed
Employees. Each Party shall comply, at its expense, with all applicable provisions of workers compensation Laws, unemployment compensation Laws, federal social security Law, the Fair Labor Standards Act, and all other applicable federal,
state, and local Laws relating to terms and conditions of employment required to be fulfilled by employers with respect to any of its Borrowed Employee. Without limiting the generality of the foregoing and for so long as any person serves as a
Borrowed Employee of a Party, such Party shall:

(a) pay such Borrowed Employee at such compensation levels (including any
overtime pay, if applicable), and provide employee benefits, as it provided such



25

RESTRICTED DUKE-BECHTEL CONFIDENTIAL INFORMATION

person prior to becoming a Borrowed Employee, subject to periodic reviews and adjustments in the ordinary course of business;

(b) make wage payments to such Borrowed Employee through its payroll systems and on the same basis as such compensation is provided to any

For the avoidance of doubt, the Parties acknowledge and agree that no Borrowed Employee shall be considered an employee of the Party to whom such
Borrowed Employee is assigned for any purposes, including HR Issues, discipline, termination, retirement benefits, workers compensation or employers liability insurance, all of which shall remain the responsibility of the Party assigning
such Borrowed Employee. Each Party assigning a Borrowed Employee hereby releases and agrees to indemnify, hold harmless and defend the other Party from and against any and all claims, demands, losses, damages, costs, liabilities and expenses
(including reasonable attorneys fees) arising out of the failure of the assigning Party to comply with its obligations in this Section 5.5. Each Party shall maintain payroll and other wage, benefit and tax records related to its
Borrowed Employees in accordance with generally accepted accounting practices and all applicable Laws. Upon written request of each Party and to the extent permitted by applicable Law, the other Party shall make available to the requesting Party its
records relating to the other Partys obligations in this Section 5.5 and its compliance with such obligations, and shall provide such certificates and copies of such receipts or vouchers, as the requesting Party may reasonably
require to assure itself that the other Party has complied with its obligations in this Section 5.5.

Technical Data), (d) Owners or any Permitted Users authorized construction or operation of the Facility as described in the Documentation
(other than any Technical Data), (e) Owners or any Permitted Users practice or exercise of the Sulfur Intellectual Property Rights, and (f) Owners or any Permitted Users authorized use of data contained in the
Documentation (other than any Technical Data) shall not infringe or constitute a misappropriation of any right of any third party, including any copyrights, mask work rights, patent rights, trademark rights, trade secret rights or confidentiality
rights of any third party. Contractor warrants that it has the right to grant the licenses purported to be granted by it herein. The foregoing warranties shall not apply with respect to Owners exercise of any intellectual property rights owned

Contractors warranties shall not be restricted in any manner by any warranty of a Subcontractor, and the refusal of a Subcontractor to provide or honor a warranty or to correct defective, deficient or nonconforming Services shall not excuse
Contractor from its liability on its warranties to Owner. Contractor shall have no liability for fabrication errors or violations of an Owner Services Contract or an Owner Equipment Contract or other defect in items supplied or work performed by
Owner Suppliers unless such items or work were prepared or performed in accordance with the Design Documentation provided by Contractor or otherwise at the direction of Contractor, in which case Contractors liability shall be limited to the
re-performance of the applicable Services that are the cause of such error, violation or defect.

12.6 Exclusive Warranties. THE
WARRANTIES SET FORTH IN THIS AGREEMENT ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER WARRANTIES, WHETHER STATUTORY, EXPRESS, OR IMPLIED (INCLUDING ALL WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, AND ALL WARRANTIES ARISING FROM

---

(a) any and all Third Party Claims and all damages, liabilities, losses, costs and
expenses associated therewith (including reasonable attorneys fees and other professionals fees) for any injury of or death to persons, damage to or destruction of third party property (other than the Facility), whether contractual, in
tort, or as a matter of strict liability or liability imposed by Law, to the extent any of the foregoing arise out of the negligence or willful misconduct of Contractor;

(b) any fines or penalties arising out of any violation or alleged violation of Laws by Contractor; and

(c) any and all claims, demands or causes of action of every kind and character by any Person and all damages, liabilities, losses, costs

Contractor and, with respect to any Hazardous Materials brought onto the Site in containers, any release of such Hazardous Materials caused by Contractor.

In no event shall Contractors indemnification obligations hereunder extend to bodily injury or property damage claims brought by employees of Managed Vendors, or any of Owners other contractors, and their respective lower-tier
subcontractors. Owner agrees that it shall use commercially reasonable efforts to cause all indemnity, release, additional insured and hold-harmless agreements contained in Owner Contracts whereby the Managed Vendors agree to indemnify, release or
hold harmless Owner or name Owner as an additional insured to extend similar protection to Contractor. Contractors liability under Section 13.1(c) shall terminate *** after the expiration of the Warranty Period.

13.2 Owners Indemnity. Owner shall indemnify and hold harmless Contractor, its parents and Affiliates and their respective partners,
shareholders, members, agents, employees, officers, directors, and lenders (collectively, the Contractor Indemnitees) from and against:

(a) any and all Third Party Claims and all damages, liabilities, losses, costs and expenses associated therewith (including reasonable attorneys fees and other professionals fees) for any injury of or
death to persons, damage to or destruction of third party property (other than the Facility), whether contractual, in tort, or as a matter of strict liability or liability imposed by Law, to the extent any of the foregoing arise out of the
negligence or willful misconduct of Owner;

(b) any fines or penalties arising out of any violation or alleged violation of
Laws by Owner; and

(c) any and all claims, demands or causes of action of every kind and character by any Person and all
damages, liabilities, losses, costs and expenses associated therewith (including reasonable attorneys fees and other professionals fees) for:

---

(i) any pre-existing environmental conditions existing at the Site and any damages or
claims resulting from Hazardous Materials brought onto or generated on the Site by any party other than Contractor, as well as any normal operational by-products; or

(ii) any mine remediation work or mine subsidence performed by or on behalf of Owner; provided, that Owners indemnity
obligations under this Section shall not extend to any failure of Contractor to address or incorporate information specifically stated in the Mine Remediation Reports.

13.3 Intellectual Property Indemnity. Contractor shall defend, indemnify and hold harmless Owner Indemnitees from and against all liabilities, actions, damages, claims, demands requests, judgments, losses,
costs, expenses, suits or actions, including reasonable attorneys fees and court costs for allegations that the Services, Documentation (other than any Technical Data), Owners or any Permitted Users authorized implementation of
processes described in the Documentation (other than any Technical Data), Owners or any Permitted Users practice or exercise of the Sulfur Intellectual Property Rights, Owners or any Permitted Users authorized construction or
operation of the Facility as described in the Documentation (other than any Technical Data), or Owners or any Permitted Users authorized use of data contained in the Documentation (other than any Technical Data) infringe any intellectual
or proprietary right of any third party, including any copyrights, patent rights, trademark rights, trade secret rights or confidentiality rights of any third party. The foregoing obligations shall not apply with respect to infringements caused
solely by Owners exercise of any intellectual property rights owned by GE (and not owned by Contractor) or any modification to the Documentation made by Owner or its Permitted Users, unless such modification was authorized in writing by
Contractor. In the event Owner terminates the Agreement pursuant to Section 19.5(b) and Owner fails to pay the License Continuation Fee identified in Section 19.5(c)(ii), then the indemnity obligations contained in this
Section 13.3 shall (i) only apply to the actions or activities (including, without limitation, the use of any Documentation) of the Owner Indemnitees taken prior to the expiration of the license granted pursuant to
Section 18.2 and (ii) survive for a period of *** from the date of such termination or expiration.

13.4 Indemnity
Procedures for Third Party Claims.

(a) In the event of a Third Party Claim with respect to which an Indemnified Party
has a claim for indemnification under this Article, then the Indemnified Party must notify the indemnifying Party thereof in writing of the existence of such Third Party Claim and must deliver copies of any documents served on the Indemnified Party
with respect to such Third Party Claim; provided, however, that any failure to notify the indemnifying Party or deliver such copies will not relieve the indemnifying Party from any obligation hereunder unless (and then solely to the
extent that) the indemnifying Party is materially prejudiced by such failure.

(b) The indemnifying Party shall have the
obligation to conduct and control, through counsel of its own choosing, reasonably acceptable to the



38

RESTRICTED DUKE-BECHTEL CONFIDENTIAL INFORMATION



---

Indemnified Party, any Third Party Claim; provided, however, that (i) the Indemnified Party may, at its election, participate in the
defense thereof at its sole cost and expense and (ii) if (A) the indemnifying Party shall fail to defend any Third Party Claim, (B) the Parties mutually agree in writing to allow the Indemnified Party to assume the defense of such
Third Party Claim and forego any indemnity claimed under this Article, (C) in the reasonable opinion of legal counsel for the Indemnified Party, such Third Party Claim involves the potential imposition of criminal liability on the Indemnified
Party, its directors, officers, employees or agents, (D) in the reasonable opinion of legal counsel for the Indemnified Party, the Third Party Claim involves, or is likely to involve, any claim by any Government Authority or (E) in the
reasonable opinion of legal counsel for the Indemnified Party, an actual or potential conflict of interest exists where it is advisable for such Indemnified Party to be represented by separate counsel, then the Indemnified Party shall be entitled to
control and assume responsibility for the defense of such Third Party Claim, at the cost and expense of the indemnifying Party. The indemnifying Party may, in any event, participate in such proceedings at its own cost and expense.

(c) The indemnifying Party, in the defense of any such litigation, other proceeding or other claim, shall have the right in its sole
discretion to settle such Third Party Claim only if (i) such settlement involves only the payment of money and execution of appropriate releases of the Indemnified Party and its Affiliates, (ii) there is no finding or admission of any
violation of Law, (iii) the Indemnified Party or its Affiliates will have no liability with respect to such compromise or settlement, and (iv) the Indemnified Party and its Affiliates will have no restriction on their respective exercise
of rights granted herein. Otherwise, no such Third Party Claim shall be settled or agreed to without the prior written consent of the Indemnified Party. The Indemnified Party and the indemnifying Party shall fully cooperate in good faith in
connection with such defense and shall cause their legal counsel, accountants and affiliates to do so, and shall make available to the other Party all relevant books, records, and information (in such Partys control) during normal business
hours, and shall furnish to each other such other assistance as the other Party may reasonably require in connection with such defense, including making employees of the Indemnified Party available to testify and assist others in testifying in any
such proceedings.

13.5 Insurance. Notwithstanding anything in this Agreement to the contrary, the indemnification obligations in
this Agreement are independent of, and shall not be limited by, any insurance required hereunder or otherwise available.

set forth in pronouncements of the Financial Accounting Standards Board (and its predecessors) and the American Institute of Certified Public Accountants, for a period of three (3) years after the Final Completion Date (or, if Final Completion

21.4 Cooperation.

(a) Contractor acknowledges that Owner is a regulated entity that is subject to the jurisdiction of the Indiana Utility Regulatory
Commission (the IURC) and other Government Authorities and, as such, must from time to time provide information about its operations, business and affairs to the IURC and such other Government Authorities. Accordingly, subject to
the procedures set forth in Section 21.4(b), Contractor shall promptly and in good faith cooperate with Owner in all requests for information by the IURC or any such Government Authority or by Owner for the IURC or any such Government
Authority, including providing testimony and such assistance and information as Owner may reasonably request and that is available to or can be developed or produced by Contractor relating to Contractor, any Subcontractor, the Services, the CM ISBL
Work, the Facility or the Project in order for Owner to comply with requests from Government Authorities having jurisdiction over it, including the IURC, irrespective of whether compliance with such request is mandated by applicable Laws.

(b) The IURC has retained the services of Black and Veatch Corporation as its advisor with respect to the Project
(B&V). Notwithstanding anything contained herein to the contrary, in the event that Owner receives an order or other request for information by the IURC or any Government Authority that Owner believes could reasonably be
expected to require the disclosure of Contractor Confidential Information, technical engineering deliverables created by Contractor, Contractors construction procedures, or Contractors proprietary estimating and pricing information,
methods and procedures that, in each case, have not been specifically created for the Project, Owner shall promptly provide notice of such order or other request for information to Contractor. Following such notice, Owner and Contractor agree to
meet promptly and in good faith to determine the process that Owner shall use in responding to such request, which may include the implementation of information access procedures necessary to control the access of B&V to such Contractor
information, in order to limit and protect the disclosure of such Contractor Information to B&V while ensuring that Owner complies with such requests in all respects.

21.5 Sales Tax Records. Contractor shall provide to Owner all information and data Owner may from time to time reasonably request and otherwise fully cooperate with Owner in connection with the reporting of
(a) any Sales Taxes payable with respect to the Services and (b) any assessment, refund claim or proceeding relating to Taxes payable with respect to the Services. Contractor shall require its Subcontractors to provide to Contractor all
information and data Contractor may reasonably request for purposes of complying with the preceding sentence and otherwise fully cooperate with Owner. Contractor shall retain, and shall require Subcontractors to retain, copies of such documentation
and all documentation relating to purchases relating to the Services or the payment of Sales Taxes, if any, for a period of not less than four (4) years from the Final Completion Date (or, if Final Completion does not occur, for four
(4) years after termination of this Agreement). Contractor shall ensure that its contracts with all Subcontractors effectuate the provision of this Section. Contractors and Owners obligations under this Section shall survive the
termination,



54

cancellation or expiration of this Agreement for any reason and shall last so long as is necessary to resolve any and all matters regarding Taxes
attributable to the Services; provided, that if Owner requires Contractor to take action under this Section at any time after two (2) years after completion of the particular item of Services, Owner shall reimburse Contractor for all actual and
reasonable expenses Contractor incurs in taking those actions.



|22. | TAXES

all Taxes on Contractors employees, purchases of goods, tools, equipment, supplies and other consumables which are not permanently incorporated into the Facility and which remain the property of the Contractor. Contractor shall also pay all
Taxes attributable to Contractors and its Subcontractors employees, construction equipment, temporary buildings and other property used by Contractor and its Subcontractors in its performance of the Services under this Agreement which
are not permanently incorporated into the Facility and which remain the property of the Contractor. Allowance for such Taxes is not included in ***, and Contractor shall pay those Taxes when assessed, without claim against Owner for reimbursement.
Contractor shall impose a similar obligation on all Subcontractors and shall ensure that no Subcontractor shall have any claim against Owner for reimbursement of those Taxes.

22.2 Sales and Use Taxes. For Sales and Use Tax purposes of the State, the Parties agree that this Agreement is a separated contract. Owner shall
pay directly when due and payable all Sales and Use Taxes. Owner shall provide to Contractor an Indiana Direct Pay Permit and ST-105 Certificate. If an audit by a Government Authority determines that any additional Sales and Use Taxes are due from
Contractor, then Owner shall reimburse Contractor for such Sales and Use Taxes promptly upon receipt of an invoice for such Sales and Use Taxes.

22.3 Tax Indemnification. Contractor shall defend, indemnify and hold harmless Owner and its Affiliates from and against all claims by any Government Authority claiming Taxes based upon gross receipts or on the income of Contractor,
its Subcontractors or their respective employees, agents or representatives derived from any payment for the Services made to or earned by such Persons under the Agreement. If required by Law or any Government Authority, Owner shall have the right
to withhold amounts, at the withholding rate specified by Law, from payments due from Owner to Contractor hereunder, and any amount so withheld shall be credited against any payment otherwise owing by Owner to Contractor under the Agreement.

22.4 Cooperation and Assistance. Contractor shall promptly notify Owner upon receipt by Contractor of any proposed tax audits or
tax assessments relating to the Services. Contractor shall assist and cooperate with Owners efforts to minimize potential tax liability by providing records and other necessary documentation to appropriate authorities in response to such

denial of any refund claim filed. Should Owner elect to protest or appeal any assessment or denial, Contractor shall reasonably cooperate and assist as
necessary with such protest or appeal. The Parties agree that any such protest or appeal shall be controlled by Owner, including choice of counsel, with Owner bearing all costs, fees and expenses in furtherance of the protest or appeal. Any and all
refunds of Taxes and interest resulting from any protest or appeal shall be solely for the account of Owner. Contractor shall impose a similar obligation in its agreements with Subcontractors.

22.6 Survival. Contractors and Owners obligations under this Article 22 shall survive the termination or expiration of the
Agreement for any reason and shall last so long as necessary to resolve any and all matters regarding Taxes attributable to the Services.



|23. | DISPUTE RESOLUTION
|--- | ------------------

23.1 Disputes. The
Parties hereby agree to submit any dispute or other controversy arising out of or relating to this Agreement, including, with respect to the arbitrability, negotiation, invalidity, termination, or breach thereof, (each a Dispute)
to resolution in accordance with this Article 23.

23.2 Meeting Regarding Dispute. In the event of a Dispute, the Parties
shall first attempt in good faith to settle and resolve such Dispute in accordance with the provisions of this Section 23.2. A Party asserting the existence of a Dispute shall notify the other Party of the Dispute in writing setting
forth the nature of the Dispute in reasonable detail. Within *** Days after delivery of any such notice by one Party to the other Party regarding a Dispute, the Parties shall meet at a mutually agreed time and place to attempt, with diligence and
good faith, to resolve and settle such Dispute (Dispute Resolution Meeting). In the event the Parties are unable to resolve the Dispute, either Party may request that the matter be referred to non-binding mediation. The Parties
agree to such non-binding mediation in Indianapolis, Indiana at a mutually agreed upon time and place with a mutually agreed neutral mediator, following procedures agreed to by the Parties or set by the mediator. Should mutual resolution and
settlement not be obtained within *** Days after the Dispute Resolution Meeting (or should no such meeting take place within such *** Day period), then either Party may, by notice to the other Party, submit the Dispute to non-administered binding
arbitration in Indianapolis, Indiana, in accordance with the International Institute for Conflict Prevention and Resolutions Rules for Non-Administered Arbitration (the CPR Rules) and the provisions of this Article
23. Judgment on the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof in accordance with the remaining provisions of this Article 23. Should the Parties agree to engage in mediation, such
proceeding shall not affect the timing or process for arbitration.

23.3 Initiation of Binding Arbitration and Selection of
Arbitrators. The Party desiring arbitration shall so notify the other Party, identifying in reasonable detail the Dispute to be arbitrated and the relief sought and file notice of arbitration in accordance with the CPR Rules. Arbitration
hereunder shall be before *** selected in accordance with the CPR Rules and qualified in the field most relevant to the issues raised in the Dispute. In the event that any Partys claim exceeds ***, exclusive of interest, the Dispute shall be
heard and



56

RESTRICTED DUKE-BECHTEL CONFIDENTIAL INFORMATION



---

determined by a three-person panel of neutral arbitrators selected in accordance with the CPR Rules and qualified in the field most relevant to the issues
raised in the Dispute.

23.4 Arbitration Procedures. The arbitrator(s) shall conduct a hearing no later than ninety (90) Days
after submission of the matter to arbitration (or such other timeframe as mutually agreed by the Parties), and a decision shall be rendered by the arbitrator(s) within thirty (30) Days of the hearing. In connection with any Dispute, the Parties
shall have such rights to discovery, including depositions, as the arbitrator(s) may permit, provided that, where the amount in controversy with respect to such Dispute is equal to or more than $***, the Parties shall have the rights to discovery
set forth in Rules 26 through 36 of the Federal Rules of Civil Procedure (or, to the extent that the proceeding involves only the Parties, in accordance with such rules of discovery as mutually agreed by the Parties). Any dispute concerning
discovery will be resolved by the arbitrator(s). Each Party will, upon the written request of the other Party, promptly provide the other with copies of documents on which the requesting Party may rely in support of a claim or defense or which are
relevant to the issues raised in the Dispute. At the hearing, the Parties shall present such evidence and witnesses as they may choose, with or without counsel. Adherence to formal rules of evidence shall not be required but the arbitrator(s) shall
consider any evidence and testimony that it determines to be relevant, in accordance with procedures that it determines to be appropriate. Any award entered in arbitration shall be made by a written opinion stating the reasons for the award made.

23.5 Consolidation. Owner, in its sole discretion, shall have the option at any time to (a) join Contractor to any arbitration
or dispute that involves Owner and any Person providing services to Owner in connection with the Project or (b) consolidate any arbitration or Dispute arising hereunder with any existing arbitration, proceeding or other similar matter which
involves Owner and any Person providing services to Owner in connection with the Project, and Contractor hereby consents to any such joinder or consolidation. If Owner and Contractor are involved in an arbitration or dispute in connection with the
Project, and Contractor reasonably believes that a third party (including GE, a Managed Vendor or a Subcontractor) is substantially involved in a common question of fact or such third partys presence is necessary if complete relief is to be
afforded and/or inconsistent decisions are to be avoided, then, Contractor shall promptly provide notice thereof to Owner requesting that such third party be consolidated into such arbitration or dispute. If Owner, in its sole discretion, agrees to
grant such request, the Parties will use their respective reasonable efforts to consolidate such third party into the applicable arbitration or dispute, making such accommodating adjustments as are fair and appropriate to accommodate additional
parties; provided, however, that such third party has consented to such inclusion and agrees to be bound by the award of the arbitrators.

23.6 Enforcement. This submission and agreement to arbitrate shall be specifically enforceable. Arbitration may proceed in the absence of a Party if notice of the proceedings has been given to such Party in accordance herewith. The
Parties agree to abide by all awards rendered in such proceedings. During the pendency of a Dispute, each Party shall continue to perform all of its respective obligations under this Agreement. If the Dispute concerns a Partys cessation of
performance under this Agreement, then that Party shall not be deemed in default under the terms of this Agreement with respect to the specific matter that is the subject



57

RESTRICTED DUKE-BECHTEL CONFIDENTIAL INFORMATION



---

of the Dispute if that Party ceased performance in what it considered in good faith to be compliant with the terms of this Agreement, during the pendency of
the Dispute.

23.7  Fees  and  Costs.  Each  Party  shall  bear  its  own  costs
 and  expenses  related  to  the  arbitration  and  mediation. The arbitrators(s) fees and mediators fees and other administrative costs of the arbitration and the mediation shall be borne
equally by the Parties.

23.8 Interim Relief. Either Party may apply to the arbitrator(s) seeking injunctive relief until the
arbitration award is rendered or the controversy is otherwise resolved. Either Party may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any interim or provisional relief that is necessary to protect the
rights or property of that Party, pending the establishment of the arbitral tribunal.

23.9 Award. The arbitrator(s) will have no
authority to award any damages precluded by Article 16.

23.10 Confidentiality. Except as may be required by applicable Law,
each Party shall treat the existence, content or results of any settlement discussion pursuant to this Article 23 or arbitration as confidential information of the other Party in accordance with the Confidentiality Agreement and shall use
commercially reasonable efforts to cause any arbitrator(s) to keep such information confidential.

24.8 Severability. If any provision of this Agreement or the
application of this Agreement to any Person or circumstance shall to any extent be held invalid or unenforceable by a court of competent jurisdiction or arbitrators under Article 23, then (i) the remainder of this Agreement and the

will be placed by Contractor in the designated eRoom created solely for Owner, Contractor and GE access (3-way eRoom) which resides on the Owners server. This 3-Way eRoom is designed for the communication exchange between
Owner/Contractor/General Electric for certain Contractor and Managed Vendor technical information.

1.2.2. COMMUNICATION TO MANAGED VENDORS

Contractor will be responsible for the day-to-day communication with Managed Vendors; provided, however that Owner reserves the right to communicate with
all Managed Vendors at its discretion but will to the extent possible coordinate such communication with Contractor. The Contractor will copy the Owner on any of its correspondence with the Managed Vendors by issuing a copy to the Duke/Bechtel
eRoom.

Contractor has established a Managed Vendor eRoom on Contractors server (Vendor eRoom) for exchanging technical data among
the Managed Vendors for review and issuance. The Managed Vendors will issue all of their respective communications and related data to the Vendor eRoom. Contractor is responsible for issuing technical data received from the Managed Vendors to Owner
into the 3-way eRoom. It is the intent of the Parties that Contractor will handle technical data received from GE in the same manner as technical data received from the Managed Vendors; ***.

1.2.3 SITE COMMUNICATION

In this integrated arrangement
some Owner personnel will directly utilize Contractor applications within the Contractor network. Only Owner personnel authorized by Contractor (and identified as account holders for this purpose) utilizing Contractor managed devices will be allowed
to connect directly to the Contractor network. Several Contractor applications will be made accessible via web based interfaces to authorized Owner personnel external to the Contractor network. Tools such as eRoom, CTI and BecTransfer will be
enabled in this capacity.

Attn: Amos A. Avidan



| | Re: | Confidentiality Agreement
| | --- | -------------------------

Dear Amos:

Duke Energy Indiana, Inc. (Duke, which term shall, for purposes of this Agreement, include its affiliates and subsidiaries) and Bechtel Power
Corporation (Bechtel, which term shall, for purposes of this Agreement, include its affiliates and subsidiaries) (Duke and Bechtel each a Party and collectively, the Parties), together with the
General Electric Company (GE), previously entered into that certain Amended and Restated Confidentiality Agreement dated as of July 26, 2007 (the Existing Confidentiality Agreement), relating to disclosure
of confidential information in connection with their respective preliminary work on the Edwardsport integrated gasification combined cycle facility (the Project). Further, the Parties previously entered into a Technical Services
Agreement effective as of February 13, 2006, as amended by Amendment No. 1 dated May 30, 2006, and another Technical Services Agreement effective as of May 7, 2007 with respect to such preliminary work relating to the Project.
The Parties are entering into negotiations relative to a definitive agreement between the Parties with respect to the Project and desire to enter into a third Technical Services Agreement, dated as of the date hereof, for purposes of undertaking
additional work for the development and construction of the Facility. As a result of such third Technical Services Agreement, the Parties now desire to enter into this confidentiality letter agreement (this Agreement), in order,
among other things, (i) for Duke to use the Confidential Information (as defined below) of Bechtel for the purposes of design, construction, maintenance, operation, repair, modification, licensing, simulation, commissioning and decommissioning
of the Project, training, consultation and compliance with laws in respect of the Project, and otherwise for Dukes internal business purposes and (ii) for Bechtel to use the Confidential Information of Duke for the purposes of fulfilling
its contractual obligations to Duke in respect of the Project (such purposes described in the foregoing clauses (i) and (ii) of this paragraph, collectively, the Purposes). Each Party furnishing its Confidential
Information shall be hereinafter referred to, with respect to such information, as the Disclosing Party, and each Party receiving such information shall be hereinafter referred to, with respect to such information, as the
Receiving Party.

All information regarding a Partys
properties, employees, finances, businesses, operations, assets, prospects, financial affairs and proprietary technology furnished or disclosed by a Disclosing Party or its Representatives (as defined below) to the other Party, whether furnished or
disclosed before or after the date hereof and regardless of the manner in which it is furnished or disclosed, that is: (i) written or electronic and clearly marked Confidential, Proprietary, Bechtel Sulfur
Confidential or Bechtel Sulfur Information1, or (ii) if furnished or disclosed orally or visually, is
identified by the Disclosing Party as being Confidential,



|1 | Attachment No. 1 hereto contains a complete definition of Bechtel Sulfur Information.
|- | ---------------------------------------------------------------------------------------



---

Proprietary, Bechtel Sulfur Confidential or Bechtel Sulfur Information at the time of such oral or visual disclosure and
also identified as such in a writing or electronic message sent by the Disclosing Party and received by the Receiving Party within ten (10) days after such disclosure, such writing or electronic message setting forth (A) the date and
approximate time of the oral or visual disclosure, (B) the names of the Representatives of each Party disclosing and receiving such oral or visual disclosure and (C) the information that was identified by the Disclosing Party at the time
of oral or visual disclosure as being Confidential, Proprietary, Bechtel Sulfur Confidential or Bechtel Sulfur Information (such information described in the foregoing clauses (i) and (ii) of
this paragraph, collectively, the Confidential Information). All such information disclosed by a Disclosing Party or its Representatives shall remain the Disclosing Partys Confidential Information notwithstanding the
inclusion of such information in summaries or other documents created by the other Party or its Representatives.

The term
Confidential Information shall not include information that: (a) is or becomes available to the public other than as a result of a disclosure by the Receiving Party or any of its Representatives (as defined below) in breach of this
Agreement or any previous agreement to which the Parties were previously bound , (b) was available to the Receiving Party on a non-confidential basis prior to its disclosure by the Disclosing Party or its Representatives from a person who was
not known by the Receiving Party or any of its Representatives to be otherwise bound by a confidentiality agreement with the Disclosing Party or any of its Representatives, or otherwise under an obligation to the Disclosing Party or any of its
Representatives not to transmit the information to the Receiving Party, (c) is developed independently by the Receiving Party or any of its Representatives without use or benefit of information disclosed by the Disclosing Party, or
(d) becomes available to the Receiving Party on a non-confidential basis from a person other than the Disclosing Party or its Representatives who is not, to the best of the Receiving Partys knowledge, otherwise bound by a confidentiality
agreement with the Disclosing Party or any of its Representatives, or otherwise under an obligation to the Disclosing Party or any of its Representatives not to transmit the information to the Receiving Party. Specific information shall not be
deemed to fall within one of the exceptions described in (a) through (d) above solely because it is contained in more general information that does fall within one of the aforementioned exceptions.

Subject to the immediately succeeding paragraph, unless otherwise agreed to in writing by a Disclosing Party, each Party agrees: (a) except as
required by law, rule, applicable regulation, stock exchange rule or disclosure requirement of the Securities and Exchange Commission (collectively, Law), to keep all Confidential Information of the other Party confidential and
not to disclose or reveal any such Confidential Information to any person other than to: (i) its directors, partners, officers and employees and those attorneys, accountants, financial advisors, consultants or other agents or advisors who are
not officers or employees and who need to know such Confidential Information for such Partys Purposes (such persons being collectively referred to herein as Representatives); (ii) in the case of Duke, Potential
Participants (as defined below) who need to know such Confidential Information to evaluate participation in the Project and who have entered into a confidentiality agreement with Duke substantially in the form attached as Attachment No. 2
hereto; (iii) contractors and vendors of Duke who need to know Confidential Information of Bechtel for Dukes Purposes and who have entered into a confidentiality agreement with Duke substantially in the form attached as Attachment
No. 2 hereto; and (iv) contractors and vendors of Bechtel who need to know Confidential Information of Duke for Bechtels Purposes and who agree in writing to keep such



---

information confidential in accordance with the terms of this Agreement; and (b) not to use, and to take commercially reasonable efforts to cause its
Representatives not to use, Confidential Information of the other Party for any purpose other than in connection with such Partys Purposes. During the period prior to substantial completion of the construction of the Project, competitors of
Bechtel identified in Schedule I attached hereto (each, a Bechtel Competitor) shall use any Confidential Information of Bechtel only for the purposes of providing technical or advisory services or off-site fabrication services in
connection with the Project and shall have first entered into a confidentiality agreement with Duke substantially in the form attached as Attachment No. 3 hereto, and Duke shall permit disclosure only to those Bechtel Competitor employees in
positions and in numbers appropriate to the scope of work contemplated (but in no event more than ten employees for any confidentiality agreement without the prior written consent of Bechtel, which consent shall not be unreasonably withheld). In no
event shall Duke allow any Bechtel Competitor to access the Project data room containing Bechtel estimate data without the prior written consent of Bechtel. Each Party will be responsible for any breach of this paragraph by any of its
Representatives. Each Party will be bound by the foregoing obligations of confidentiality hereunder for a period of five (5) years from the date hereof. With respect to Bechtel Sulfur Information, the Receiving Partys obligation shall be
evergreen, so long as such information shall not be available to the public, and have no termination.

In connection with the Project, Duke
may deem it necessary or advisable to discuss the Project with one or more third parties with respect to such third parties potential participation with respect to the Project (each, a Potential Participant). In this regard,
it may be necessary or advisable for Duke to disclose to a Potential Participant Bechtels Confidential Information. Bechtel hereby consents to any future discussions between Duke and any Potential Participants with respect to the Project and
to the disclosure of Bechtel Confidential Information by Duke to any and all Potential Participants, so long as such Potential Participant has entered into a confidentiality agreement with Duke on the terms set forth in the preceding paragraph.
Notwithstanding the foregoing, in the event that Duke does not pursue participation in the Project with a Potential Participant, but continues work on the Project with Bechtel, Duke agrees not to thereafter disclose, and will direct its
Representatives not to thereafter disclose, to such Potential Participant any further Confidential Information of Bechtel, subject to the exceptions set forth in this Agreement.

The Parties acknowledge and agree that Bechtel and GE are parties to an agreement protecting the confidentiality of each of their respective Confidential
Information. Accordingly, and notwithstanding anything to the contrary herein, (a) Duke and its Representatives shall be free to disclose Bechtels Confidential Information (unless marked Restricted Duke-Bechtel Information or
something substantially similar that indicates that disclosure to GE is not permitted), including Bechtel Sulfur Information, to GE and its affiliates without first entering into any agreement therewith regarding protection of Bechtels
Confidential Information and (b) Duke shall have no liability to Bechtel or to any third party for the failure or alleged failure of GE or any of its affiliates to protect the confidentiality of Bechtels Confidential Information.

In the event that a Receiving Party or any of its Representatives is legally compelled, pursuant to a subpoena, civil investigative
demand, regulatory demand or other process or Law, to disclose any Confidential Information of the other Party, such Receiving Party agrees



---

that it will provide the Disclosing Party with prompt notice of such request or requirement (if legally permissible to do so) to enable the Disclosing Party,
at the Disclosing Partys sole expense, to seek an appropriate protective order or other remedy, to consult with the Receiving Party with respect to the Disclosing Party taking steps to resist or narrow the scope of such request or legal
process, or to waive compliance, in whole or in part, with the terms of this Agreement. In any such event, the Receiving Party will use commercially reasonable efforts to ensure that all such Confidential Information of the other Party that is so
disclosed will be accorded confidential treatment and shall furnish only that portion of such Confidential Information that the Receiving Party is advised by counsel is legally required. If, in the absence of a protective order, the Receiving Party
or any of its Representatives is compelled to disclose Confidential Information of the other Party as a matter of Law, the Receiving Party shall disclose only that part of such Confidential Information as is required by Law to be disclosed (in which
case, prior to such disclosure, the Receiving Party will, to the extent practicable and permissible, advise and consult with the Disclosing Party and its counsel as to such disclosure and the nature and wording of such disclosure), and, to the
extent practical in the circumstances, the Receiving Party will use its reasonable efforts to obtain confidential treatment for any Confidential Information so disclosed.

In connection with the Project, Duke may deem it necessary or advisable to discuss certain matters relating to the Project with the Midwest Independent System Operator (MISO), the Indiana Utility Regulatory Commission
(IURC), the Indiana Department of Environmental Management (IDEM), the Indiana Office of Utility Consumer Counselor (OUCC), the federal Environmental Protection Agency (EPA), or other similar entity whose involvement or approval is necessary or
prudent for carrying out the Project or the work required by other agreements between the Parties. In this regard, it may be necessary or prudent for Duke to disclose to such persons the proposed terms thereof or Bechtels Confidential
Information. In holding such discussions, Duke undertakes to convey to such persons the importance of maintaining confidentiality with respect to the matters that are discussed. Accordingly, Bechtel hereby consents to discussions between the
foregoing persons, on the one hand, and Duke and its Representatives, on the other, regarding regulatory matters pertinent to the Project and Duke may disclose Confidential Information of Bechtel to MISO, IURC, IDEM, OUCC, EPA or other similar
entity in such discussions.

Each Receiving Party acknowledges that Confidential Information is and at all times remains the sole and
exclusive property of the Disclosing Party, and the Disclosing Party has the exclusive right, title and interest to its Confidential Information. No right or license, by implication or otherwise, is granted by the Disclosing Party as a result of
disclosure of Confidential Information under this Agreement, but such right or license may arise as specified in any prior or future agreements between the Parties.

Each Receiving Party acknowledges that no Disclosing Party nor any of its Representatives, by its signature below, makes any express or implied representation or warranty as to the accuracy or completeness of its
Confidential Information, and each Receiving Party agrees that none of such persons, by sole reason of this Agreement, shall have any liability to any Receiving Party or any of its Representatives relating to or arising from the use of any
Confidential Information by the Receiving Party or its Representatives or for any errors therein or omissions therefrom. For the avoidance of doubt, the foregoing shall not negate or restrict any express or implied representation or warranty
relating to the accuracy or completeness of a



---

Partys Confidential Information arising as specified in any other agreements between the Parties.

This Agreement binds the Parties only with respect to the matters expressly set forth herein and nothing in this Agreement shall bind any of the Parties
to other specific terms or conditions relating to the Project. Neither of the Parties is bound or committed to negotiate or consummate the Project by virtue of this Agreement unless and until a definitive agreement on such matters between the
Parties has been executed and delivered on behalf of each such Party by its duly authorized officer.

Each Receiving Party is aware, and
will advise its Representatives who are informed of the matters that are the subject of this Agreement, of the restrictions imposed by the United States securities laws on the purchase or sale of securities by any person who has received material,
non-public information from the issuer of such securities and on the communication of such information to any other person when it is reasonably foreseeable that such other person is likely to purchase or sell such securities in reliance upon such
information. Each Receiving Party hereby confirms that it, and its Representatives, will take any action necessary to prevent the use of any information about any Disclosing Party in a way which might violate any antitrust or other applicable Law.

Notwithstanding anything to the contrary herein, Duke shall have the right to permit visitors to tour the Edwardsport integrated
gasification combined cycle facility without entering into any confidentiality agreement with such visitors prior to such tour.

It is
understood that the covenants of this Agreement and the Confidential Information disclosed are special, unique and of extraordinary character. Each Disclosing Party may be irreparably harmed by a breach of this Agreement by a Receiving Party, and
the use of the Confidential Information for the business purposes of any person other than the Disclosing Party may enable such person to compete unfairly with the Disclosing Party. Without prejudice to the rights and remedies otherwise available to
each of the Parties, each Party shall be entitled to seek equitable relief by way of injunction or otherwise if another Party or any of its Representatives breaches or threatens to breach any of the provisions of this Agreement. It is further
understood and agreed that no failure or delay by a Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the
exercise of any right, power or privilege hereunder.

Each Party shall be responsible for the costs and expenses incurred by it and its
Representatives in carrying out the purposes of this Agreement.

This Agreement shall be governed by and construed in accordance with the
laws of the State of Indiana applicable to contracts executed in and to be performed in that state.

This Agreement shall be binding on the
Parties and their respective successors and permitted assigns. Any assignment of this Agreement, in whole or in part, by either Party without the prior written consent of the other Party hereto shall be null and void ab initio.

This Agreement is solely for the benefit of the Parties, and this Agreement shall not be deemed to confer upon or give to any third party any remedy,
claim of liability or reimbursement, cause of action or other right.



---

If any provision of this Agreement is held by a court of competent jurisdiction to be invalid, illegal or
unenforceable, the remainder of the provisions of this Agreement shall remain in full force and effect. The Parties shall endeavor in good faith negotiations to replace any invalid, illegal or unenforceable provision with a valid, legal and
enforceable provision, the effect of which comes as close as possible to that of the invalid, illegal or unenforceable provision.

No
modification of this Agreement or waiver of the terms and conditions hereof shall be binding upon the Parties, unless approved in a writing signed by each of the Parties.

This Agreement contains the entire agreement among the parties concerning the subject matter hereof and supersedes any and all previous understandings or agreements, whether written or oral, pertaining to said subject
matter, including the Existing Confidentiality Agreement, which is hereby terminated with respect to Duke and Bechtel without surviving obligations. This Agreement may be executed in counterparts, each of which shall be an original, but all of which
together shall constitute one and the same agreement.

Bechtel shall not, and shall not permit any of its Representatives to, issue any
press or publicity release, concerning this Agreement, the Project or any other agreement between the Parties relating to the Project without the express prior written consent of Duke, which shall not be unreasonably withheld.

Please acknowledge your agreement to the foregoing by countersigning this Agreement in the space provided below and returning to the undersigned a fully
executed original copy of this Agreement.

Sincerely,

---

Form Non-Disclosure and Secrecy Agreement

THIS NON-DISCLOSURE AND SECRECY AGREEMENT (this Agreement) is entered into as of the      day of
                    , 20        , between Duke Energy Indiana, Inc., an Indiana corporation having its
principal place of business in Charlotte, North Carolina (Duke Energy), and
                                        , a
                         [corporation] having its principal place of business in
                         (the Company). Duke Energy and the Company shall sometimes be individually referred
to herein as a Party and collectively as Parties.

R E C I T A L S:

A. Duke Energy is developing an integrated gasification combined cycle facility in Edwardsport, Indiana (the Facility).

B. Duke Energy and the Company are engaged in, or intend to engage in, discussions pursuant to which [(a) Duke Energy may engage the Company to
construct, operate, maintain, modify, repair, test, train, commission, decommission, license or inspect the Facility, or (b) the Company may consider purchasing all or a portion of the Facility]. [Tailor to purposes in connection with
the Company.]

C. The Parties acknowledge that each Party may make available to the other Party, from time to time, in connection with
the aforementioned purposes, certain Confidential Information (as defined below), including Confidential Information belonging to General Electric Company or its affiliates (collectively, GE) or Bechtel Power Corporation or its
affiliates (collectively, Bechtel) that is disclosed by Duke Energy, GE or Bechtel, as applicable, to the Company.

NOW,
THEREFORE, in consideration of the premises and the mutual promises and covenants hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by each Party, the Parties, intending
to be legally bound, agree as follows:

1. Definitions. As used in this Agreement,

(a) Confidential Information means all nonpublic information disclosed by, or on behalf of, a Party (or, with respect to disclosures of
GE or Bechtel nonpublic information to the Company, GE or Bechtel, as applicable) (the Disclosing Party) to the other Party (the Receiving Party) or its Representatives (as defined below), whether disclosed
before or after the date hereof (including any information disclosed under any previous confidentiality agreements) and regardless of the manner or format of such disclosure, that: (a) is designated in writing as confidential,
proprietary, GE Gasification Information, Bechtel Sulfur Information, or similar designation by the Disclosing Party at the time of written disclosure; (b) a reasonable person in the power generation industry
would understand to be confidential or proprietary by virtue of its nature; or (c) is orally or visually disclosed and confirmed and designated by the Disclosing Party to be confidential or proprietary in writing within
thirty



---

(30) days after such oral or visual disclosure. Once orally or visually disclosed information has been designated as Confidential or as a similar
designation, all future disclosures of such information shall be protected, regardless of whether such future disclosures are marked or designated as Confidential or with a similar designation. Confidential Information shall
not include any information that: (i) was publicly available prior to disclosure thereof to a Receiving Party or its Representatives by a Disclosing Party; (ii) becomes publicly available after disclosure thereof to a
Receiving Party or its Representatives by a Disclosing Party other than as a result of a public disclosure by such Receiving Party or its Representatives; (iii) is at the time of its disclosure to a Receiving Party or its Representatives, or
becomes thereafter, available to the Receiving Party or its Representatives on a non-confidential basis from a source other than the Disclosing Party and such source is not, to the best of the Receiving Partys knowledge, subject to a
confidentiality obligation to the Disclosing Party regarding such information; (iv) is independently developed by a Receiving Party or its Representatives without reference to the Disclosing Partys Confidential Information; or (v) is
approved for disclosure in writing by the Disclosing Party. Specific information shall not be excluded from the above obligations merely because it is embraced by more general information excluded under items (i), (ii) or (iii) above. A
specific combination of features or items shall not be so excluded unless the specific combination itself falls within items (i), (ii) or (iii) above; and

(b) GE Gasification Information has the meaning set forth on Schedule A hereto, which is hereby incorporated by reference into this Agreement; and

(c) Bechtel Sulfur Information has the meaning set forth on Schedule B hereto, which is hereby incorporated by reference into this
Agreement; and

(d) Representative means (i) any affiliate, director, officer, employee, agent, advisor or other
representative of a Disclosing Party or Receiving Party, as the case may be, and (ii) any contractor or vendor who needs to know the Confidential Information to construct, operate, maintain, modify, repair, test, train, commission,
decommission, license or inspect the Facility and who enters into a Non-Disclosure and Secrecy Agreement with the Receiving Party in substantially the form hereof with Duke Energy, as well as GE and Bechtel, as third party beneficiaries thereof.

2. Non-Disclosure. Subject to Section 4 below, the Receiving Party shall (a) take reasonable precautions to prevent
unauthorized disclosure or use of Confidential Information disclosed to it by, or on behalf of, the Disclosing Party, such precautions taken being at least as great as the precautions taken by the Receiving Party to protect its own Confidential
Information (but in no case less than reasonable care), and (b) not disclose Confidential Information disclosed to it or its Representatives by, or on behalf of, the Disclosing Party to any third party (other than Duke Energys
Representatives) without the Disclosing Partys prior written authorization. Notwithstanding the foregoing, the Receiving Party may disclose Confidential Information of the Disclosing Party to any Representative of the Receiving Party,
provided that the Receiving Party agrees to be responsible for each such Representatives compliance with the terms hereunder binding on the Receiving Party. Duke Energy and the Company agree that Bechtel and GE are third party
beneficiaries of this Agreement.



---

3. Authorized Uses. The Receiving Party and its Representatives shall use any Confidential
Information disclosed to them by, or on behalf of, the Disclosing Party only (a) to the extent required to construct, operate, maintain, modify, repair, test, train, commission, decommission, license or inspect the Facility or (b) in the
consideration of purchasing all or a portion of the Facility.

4. Required Disclosure. Notwithstanding anything to the contrary in
this Agreement, a Receiving Party or its Representatives may disclose Confidential Information disclosed to it by, or on behalf of, the Disclosing Party if required, according to a good faith belief by Receiving Partys or its
Representatives legal counsel, by law, legal process or a government authority. If a Receiving Party or its Representative is legally compelled to disclose Confidential Information disclosed to it by, or on behalf of, the Disclosing Party, or
if such disclosure is necessary in order to comply with laws or obtain or maintain governmental approvals, applications or exemptions, the Receiving Party or its Representative must provide (if legally permissible to do so) the Disclosing Party with
as much advance written notice as practicable to afford the Disclosing Party the opportunity to seek a protective order or other remedy to prevent disclosure. If such protective order or other remedy is not obtained, the Receiving Party or its
Representative, as applicable, shall furnish only that portion of the Confidential Information disclosed to it by, or on behalf of, the Disclosing Party that is required in the opinion of its legal counsel and shall cooperate with the Disclosing
Party, at the Disclosing Partys expense, to enable the Disclosing Party to obtain a protective order or other reliable assurance that confidential treatment will be accorded the same.

5. Grantbacks. In the event the Company should obtain a patent, trade secret, or other intellectual property right, including, without limitation,
an improvement to or a modification of GE Gasification Information, or equipment or materials used therein, based on or resulting from access to or use of Confidential Information of GE furnished by Duke Energy or GE, the Company agrees to grant and
hereby grants an irrevocable, royalty-free, non-exclusive license to GE under such patent and/or such other intellectual property right, together with the right to extend such license to licensees of GE, all without accounting to the Company
therefor.

6. Return or Destruction of Confidential Information. If any Party decides that it does not wish to continue discussions
with respect to the Facility, such Party will promptly notify the other Party of that decision by giving a written termination notice. In such case or at any time for any reason, upon the written request of the Disclosing Party, the Receiving Party
will, and will cause its Representatives to, promptly, (i) deliver to the Disclosing Party all original Confidential Information (whether written or electronic) furnished to the Receiving Party or its Representatives by or on behalf of the
Disclosing Party, and (ii) if specifically requested by the Disclosing Party, destroy any copies of such Confidential Information (including any extracts therefrom); provided, however, so long as the Company is not in breach of any term of this
Agreement with respect to Confidential Information of GE or Bechtel, the Company shall not be required to return or destroy Confidential Information at the request of GE or Bechtel, as applicable, to the extent the Company requires such Confidential
Information to perform its obligations with respect to the Facility. Upon written request of the Disclosing Party for any reason, the Receiving Party shall, and shall cause its Representatives to, cause one of its duly authorized officers to certify
in writing to the Disclosing Party that the requirements of the



---

preceding sentence have been satisfied in full. Notwithstanding the termination of any discussions with respect to the Facility or the return or destruction
of any Confidential Information, the Receiving Party will continue to be bound by terms of this Agreement as provided herein.

7.
Miscellaneous.

(a) Neither this Agreement nor any right, remedy, obligation or liability arising hereunder shall be assigned by any
Party (whether by operation of law or otherwise), and any such assignment shall be null and void, except with the prior written consent of the other Party. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of
the Parties and their respective successors and permitted assigns.

(b) The Parties acknowledge and agree that no failure or delay by a
Party in exercising any right or privilege hereunder shall operate as a waiver thereof. The provisions of this Agreement may be modified or waived only in writing signed by the Party from whom compliance is sought.

(c) The Company agrees that neither GE nor Bechtel (i) makes any warranty to the Company as to the accuracy or completeness of the Confidential
Information of GE or Bechtel; or (ii) shall have any liability to the Company resulting from the use of any Confidential Information of GE or Bechtel.

(d) This Agreement shall be governed by and construed in accordance with the laws of the State of Indiana, without regards to the principles of conflicts of laws thereof.

(e) This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one
and the same instrument. A facsimile of any signature shall have the same force and effect as an original.

(f) Each Party acknowledges and
agrees that money damages would not be a sufficient remedy for any breach of this Agreement by such Party and that the other Party shall be entitled to seek equitable relief, including seeking an injunction and specific performance, as a remedy for
any such breach. Such remedies shall not be deemed to be the exclusive remedies for a breach of this Agreement, but shall be in addition to all other remedies available at law or equity.

(g) This Agreement constitutes the entire agreement between the Parties with respect to the subject matter herein and supersedes and cancels any prior
agreements, representations, warranties, or communications, whether oral or written, between the Parties relating to the subject matter herein.

effect. The Parties specifically acknowledge that the absence of a time limitation in this Agreement is reasonable and properly required for the protection of each Confidential Information disclosed by each Party hereunder. In the event that the
absence of such limitation is deemed by a court of competent jurisdiction to cause this Agreement to be invalid or unenforceable, then the Parties specifically intend for such court to impose any such time limitation as such court shall deem
reasonable.

IN WITNESS WHEREOF, each party hereto has executed this Agreement, or caused this Agreement to be executed on its behalf, all
as of the day and year first above written.

SCHEDULE A

GE Gasification Information shall mean Confidential Information provided, directly or indirectly, by Duke Energy to the Company that is proprietary solely to GE, marked as GE Gasification Information or
similar term and that describes: (1) the manufacture of synthesis gas (hydrogen and carbon monoxide) in a secret and proprietary process; and (2) its integration with other elements for: (a) electric power generation; (b) high
purity hydrogen production; and (c) carbon capture, as described below.



|(1) | The manufacture of synthesis gas in this context refers to the following:
|--- | -------------------------------------------------------------------------

Processes for producing synthesis gas, also known as reducing gas, or fuel gas, via the partial oxidation of solid, liquid and/or gaseous hydrocarbonaceous feedstocks, or combinations thereof, with oxygen, such as in
the form of high purity oxygen, enriched air, or air, for the handling, preparation, and introduction of the feeds into the synthesis gas generation process, including any temperature moderators, such as steam, water, nitrogen, or carbon dioxide,
for heating, cooling or recovering waste energy from feed, internal, or product streams, for separating contaminants from the synthesis gas, or otherwise purifying or processing the synthesis gas for its end use, and for recovering and processing
the contaminants and waste solids for recycle, for disposal, or to form useful byproducts. Quantities, pressures, temperatures, compositions, and certain physical and chemical properties of each of the associated streams are included in this
definition. The configuration of control systems that monitor or govern the flow of these streams and the operation of the process, as well as the process design of the equipment and the mechanical design of the GE proprietary equipment used in and
for these processes, are also included.



|(2) | The integration of the gasification process with:
|--- | -------------------------------------------------



| | (a) | that for electric power generation in this context refers to the following:
| | --- | ---------------------------------------------------------------------------



| | (i) | Processes for heat exchange between the gasification section, the air separation unit (ASU), and the combined-cycle power island utilizing steam, syngas, and water. Quantities,
compositions, pressures, and temperatures of each of these streams are included in this definition. Configuration of control systems that monitor or govern the flow of these streams, as well as the thermal design of the Heat Recovery Steam Generator
and other heat exchange equipment are also included.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Processes that utilize and integrate the flow of compressed air between the gasification, ASU, and power plant sections and processes that utilize flows of diluents
to the syngas fed to the combustion turbine. This includes the exchange of air and fuel diluent streams between the gasification section, the ASU, and the combustion turbine including these streams quantities, temperatures, pressures, and
compositions. The configuration of control systems that monitor or govern these streams are also included in this definition. Fuel diluent streams are those streams that
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | are used to enhance the power plants output and to reduce emissions of NOx from the combustion turbine. These diluent streams may include, but are not
limited to, nitrogen, steam, water, and carbon dioxide.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Control systems configuration and execution, including software that is involved in the feedback, feed-forward, and hybrid systems that govern the relationship of fuel flow, oxygen
flow, diluent flow, and power plant output.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | that for hydrogen production in this context refers to the following:
| | --- | ---------------------------------------------------------------------

Processes that increase the yield of hydrogen in the synthesis gas by reacting steam or water with carbon monoxide in the synthesis gas to form additional hydrogen, for separating and concentrating the hydrogen to
form one or more gaseous streams of higher hydrogen purity, such as high purity hydrogen, for modifying the pressure of the feed and product streams, for heating, cooling or recovering waste energy from feed, intermediate, or product streams, for
recycling hydrogen and non-hydrogen containing gases to increase the net yield of hydrogen, and for otherwise purifying, or removing or recovering contaminants from hydrogen-enriched and other product gases, including the synthesis gas. Quantities,
pressures, temperatures, and the compositions of each of the associated streams are included in this definition. Control systems that monitor or govern the flow of these streams and the operation of the process, as well as the mechanical design of
the equipment used in and for these processes, are also included.



| | (c) | that for carbon capture in this context refers to shift conversion, purification, membrane separation, acid gas removal and/or compression including any means or methods for
integrating said combination, and any modifications or improvements to any of the foregoing for the purpose of producing carbon dioxide.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For
the avoidance of doubt, the physical byproducts of sulfur and slag are not included within the definitions of GE Gasification Information or Confidential Information.
