2.3 Utility Services.

(a) The Westlake Parties are party to various contracts with utilities and other parties pursuant to which the Ethylene Assets and the Westlake Facilities receive electricity, natural gas, nitrogen, water and other utility services described on Schedule 4 (collectively, the “Utility Services”) necessary to operate and maintain the Ethylene Assets, the Westlake Facilities and the Common Facilities. Subject to the terms and provisions of this Agreement, the Westlake Parties shall use commercially reasonable efforts to make available to Owner electricity, natural gas, fuel gas, boiler feed water, cooling water, potable water, steam, process steam and such other services as may be needed to operate the Ethylene Assets. The quality, standards and specifications for such Utility Services shall be suitable for the operation of the Common Facilities and the Ethylene Assets in accordance with standards and quality being used in the operation of the Common Facilities and the Ethylene Assets as of the date of this Agreement or as may be reasonably requested by Owner based upon changed needs. It is understood that the Utility Services are furnished by outside providers who supply services to the Westlake Facilities and that Owner shares the expense related to such services in accordance with this Agreement. The Westlake Parties are not public utilities or common carriers and do not sell, provide or furnish utility services or utilities, and are not in the business of selling, providing or furnishing such services or utilities, but rather share the costs thereof in accordance with this Agreement.

(b) Owner shall provide the Westlake Parties with timely information regarding any changes in Owner’s requirements for Utility Services and the Westlake Parties shall consult with Owner and consider Owner’s interest on an equal footing along with the interests of the Westlake Parties concerning any negotiations with third parties from whom the Westlake Parties obtain or propose to obtain Utility Services relating to the Common Facilities or the Ethylene Assets.

(c) The Westlake Parties shall not enter into contracts with third Persons with respect to the provision of Utility Services to the Ethylene Assets without the prior written consent of Owner, which consent shall not be unreasonably withheld. At the request of Owner, the Westlake Parties shall use commercially reasonable efforts to (i) add Owner as a party to the Westlake Parties’ utility contract or (ii) reach a mutually acceptable accommodation with one or more of the Westlake Parties’ utility providers whereby each Party would be able to receive utility services on an individual basis.

(d) Notwithstanding anything to the contrary, in the event that the Westlake Parties’ delivery of electricity, water or other Utility Service to Owner is challenged before a judicial, regulatory or administrative body and the Westlake Parties determine, in their sole judgment, that it is likely that such body will determine that, in connection with such challenge, the Westlake Parties or their affected Affiliate will be subject to regulation under Applicable Law as a consequence of such delivery of electricity, water or other Utility Service (including the regulation or classification of the Westlake Parties or such Affiliate, as the case may be, as a “utility,” “public utility,” “retail public utility,” “electric utility,” “retail electric utility,” “common carrier,” “water and sewer utility” or similar designation), then the Westlake Parties and Owner will cooperate in an attempt to restructure the provision of such Service in a manner which will not subject the Westlake Parties to such regulation (provided that any such restructure does not materially and unreasonably interfere with the Westlake Parties’ or Owner’s operations or cause significant net economic detriment to the Westlake Parties or Owner). If such restructuring efforts are unsuccessful or not reasonably practicable, then the Westlake Parties shall have the right to require Owner to obtain from a third party such electricity, water or other Utility Service that would cause the Westlake Parties to be subject to regulation as a utility, and the Westlake Parties will cooperate with Owner in connection therewith and shall grant such access rights or similar rights as may be reasonably necessary for such Utility Service to be so provided to Owner. In the event that a challenge proceeds despite restructuring, then the Westlake Parties will provide notice to Owner of any such challenge and the Westlake Parties and Owner will cooperate to resist the challenge. The cost of resisting such challenge pursuant to a mutually agreed upon course of action shall be paid equally by the Westlake Parties and Owner. Any penalty, fee or fine imposed on the Westlake Parties or their Affiliate, as a result of the Westlake Parties’ delivery of electricity, water or other Utility Service to Owner shall be shared pro rata by the Westlake Parties and Owner in proportion to the consumption of the Utility Service being challenged. If such challenges and restrictions are removed, pursuant to appeal or otherwise, so that the Westlake Parties and their Affiliates will not be subject to such regulation, Owner will resume receipt of the affected Utility Service in accordance with the terms of this Agreement.

(e) If the Westlake Parties become aware of any planned or actual outage or involuntary reduction with respect to any of the Utility Services, the Westlake Parties shall promptly give notice thereof to Owner and the Westlake Parties shall coordinate such outage or reduction as nearly as reasonably practicable on a Non Discriminatory Basis so as to minimize adverse impact on each Party’s respective operations (with the standard being the equitable allocation of such Utility Services between the Westlake Facilities and the Ethylene Assets).

2.4 Permits.

(a) Subject to section 3.5 of each of the Site Lease Agreements, the Westlake Parties shall use commercially reasonable efforts to (i) obtain and maintain with respect to the Ethylene Assets, the Westlake Facilities and the Common Facilities, all Permits for which Owner is not a necessary and indispensable party, including with respect to Environmental Law, reasonably necessary in connection with the ownership or operation thereof, and (ii) use commercially reasonable efforts to comply with all conditions and requirements imposed by such Permits, including all sampling, testing and monitoring required by any Permit or Governmental Authority in connection with any Permit.

(b) Owner shall cooperate in all reasonable respects with the Westlake Parties in Westlake’s obtaining and maintaining all necessary Permits, including Owner’s signing, submitting and prosecuting all applications or submissions for Permits with respect to the Ethylene Assets for which Owner is a necessary and indispensable party and taking every other action reasonably required of Owner to enable the Westlake Parties to perform their obligations under Section 2.4(a). Owner shall notify the Westlake Parties promptly of any written notification that

Owner receives of any investigation, proceeding or other action commenced by any Governmental Authority relating to any such Permit or Applicable Law with respect to the Ethylene Assets. Owner shall promptly provide the Westlake Parties with copies of any and all written notices or other communications received by Owner from any Government Authority with respect to the Ethylene Assets and, at the reasonable request of the Westlake Parties, any other information or document that is within Owner’s possession relating to such Ethylene Asset Permits or any Westlake obligations thereunder.

2.5 Consultations.

(a) The Westlake Parties and Owner agree to meet for the purpose of coordinating outages or involuntary reductions in the availability of the Common Facilities on a Non-Discriminatory Basis so as to minimize adverse impact on each Party’s respective operations (with the standard being the equitable allocation of such services between the Westlake Facilities and the Ethylene Assets).

2.6 Relationship of the Parties. At all times during the performance of the Shared Services hereunder, all Persons performing such Shared Services (including agents, temporary employees, independent third parties and consultants) shall be construed as being independent from the Owner, and such Persons shall not be considered or deemed to be an employee of Owner or its Affiliates nor entitled to any employee benefits of Owner or its Affiliates as a result of this Agreement. Notwithstanding anything to the contrary expressed or implied, this Agreement shall not constitute or create any agency, joint venture, partnership or other fiduciary relationship or any fiduciary duty or fiduciary obligation, all of the same being hereby expressly disclaimed and waived.

which delegation of authority shall include the right to further delegate such authority to others. If any of the Services are delegated to and performed by an Affiliate of a Party or an employee of a Party or an employee of any Affiliate of a Party, Section 9.1 shall apply thereto.

7.2 Personnel and Secondment.

(a) Pursuant to Section 3.1, the Westlake Parties shall provide, or cause to be provided, to Owner the Seconded Employees (as defined in Section 7.2(b) below) and such other Persons (including consultants and professionals, service or other organizations)) as the Westlake Parties deem necessary or appropriate in order to perform the Operating Services in an efficient and prudent manner. Subject to the Westlake Parties’ right to be reimbursed for such expenses in accordance with the Accounting Procedures, each Westlake Party shall pay all expenses incurred by it in connection with the retention of the Seconded Employees and such other Persons, including, but not limited to, compensation, salaries, wages and overhead and administrative expenses, charges to or incurred by such Westlake Party, and, if applicable, social security taxes, workers compensation insurance, retirement and insurance benefits and other such expenses. Any such Seconded Employees and other Persons retained by any Westlake Party may be union or non-union employees, and the Westlake Parties shall have the sole right to negotiate the terms and provisions of any labor or other agreements with the unions to which such employees belong. The Westlake Parties shall provide, or cause to be provided, all workers who will perform Services.

(b) During the term of this Agreement, the Westlake Parties shall, from time to time, designate certain of their employees to be seconded to Owner to perform duties at the Owner’s assets or facilities or otherwise work on behalf of Owner in accordance with and subject to the terms of this Agreement. Each such employee who the Westlake Parties second to Owner shall, during the time that such employee is seconded to Owner under this Agreement (the “Period of Secondment”), be referred to individually herein as a “Seconded Employee” and, collectively, as the “Seconded Employees.”

(c) The Westlake Parties will give notice to each Seconded Employee at times and in the normal processes by which it gives similar notices to employees or otherwise in its discretion. The notices will include that (i) each such Seconded Employee will be a joint employee of the Westlake Parties and Owner, and (ii) for any work place injury, the Seconded Employee’s sole remedy against either the Westlake Parties or Owner will be under the workers’ compensation insurance policy or qualified self-insured program of the Westlake Parties. For the avoidance of doubt, the Parties acknowledge that the Seconded Employees will, during the Period of Secondment, be called upon to perform services for both Owner and the Westlake Parties of the same or closely-related nature. The Westlake Parties retain the right to terminate the secondment of any Seconded Employee for any reason at any time or to hire or discharge the Seconded Employees with respect to their employment with the Westlake Parties. Owner will have the right to terminate the secondment to it of any Seconded Employee for any reason at any time, upon prior written notice to the Westlake Parties, but at no time will Owner have the right to terminate any Seconded Employee’s employment by the Westlake Parties. Upon the termination of the secondment of any Seconded Employee, such Seconded Employee will cease performing services for Owner.

(d) In the course and scope of performing any Seconded Employee’s job functions for Owner, the Seconded Employee will report into Owner’s management structure, and will be under the direct management, supervision, direction and control of Owner with respect to such Seconded Employee’s performance of the Operating Services and day-to-day activities.

(e) Those Seconded Employees who serve as supervisors or managers and who are called upon to oversee the work of Seconded Employees working at Owner’s assets or facilities or to provide management support on behalf of Owner are designated by Owner as supervisors to act on the behalf of Owner in supervising the Seconded Employees pursuant to Section 7.2(d) above.

(f) With respect to Owner’s operations in Texas, the Westlake Parties shall obtain workers’ compensation coverage as defined by Texas Labor Code Section 401.011(44) on behalf of both the Westlake Parties and Owner, and Owner shall be considered an employer solely for the purposes of Texas Labor Code Section 401.011(18) and Section 408.001. With respect to the Owner’s operations in Kentucky, the Westlake Parties shall obtain workers’ compensation coverage as defined by Kentucky Revised Statute Section 342.340 on behalf of both the Westlake Parties and Owner, and Owner shall be considered an employer solely for the purposes of Kentucky Revised Statute Section 342.630 and Section 342.690. With respect to the Owner’s operations in Louisiana, the Westlake Parties shall obtain workers’ compensation coverage as defined by Louisiana Revised Statute Section 23:1168 on behalf of both the Westlake Parties and Owner, and Owner shall be considered an employer solely for the purposes of Louisiana Revised Statute Section 23:1031 and Section 23:1032. With respect to Owner Group operations performed in any jurisdiction other than Texas, Kentucky, or Louisiana, the Westlake Parties shall obtain workers’ compensation coverage as defined and required by Law on behalf of both the Westlake Parties and Owner, provided that Owner shall be considered an employer solely for the purposes of its status as a dual, joint- or co-employer under the relevant workers’ compensation regime. For the avoidance of doubt, nothing in this Agreement has any effect on the right of a Seconded Employee to prosecute a workers’ compensation claim against Owner, the Westlake Parties, or both.

(g) Owner and the Westlake Parties acknowledge that the services provided for under this Agreement are an integral part of and essential to the ability of Owner to generate the goods, products, and services of Owner, and to enable Owner to fulfill its business and commercial contracts, which are the core of its business. By executing this Agreement, Owner undertakes to execute work that is part of its trade, business, and occupation. Owner and the Westlake Parties expressly recognize Owner as the statutory employer of the Seconded Employees for workers’ compensation purposes, whether those employees be direct employees or statutory employees of the Westlake Parties. Notwithstanding anything in this Section 7.2(g), Owner remains the joint employer, with the Westlake Parties, of the Seconded Employees when under secondment, and should any conflict be found between this Section 7.2(g) and Section 7.2(c), Section 7.2(c) shall predominate.

(h) Owner shall not be a participating employer in any benefit plan of any Westlake Party. The Westlake Parties shall remain solely responsible for all obligations and liabilities arising with respect to any benefit plans relating to any Seconded Employees and Owner shall not assume any benefit plan or have any obligations or liabilities arising thereunder, in each case except for costs properly chargeable to Owner.

ARTICLE VIII

BUDGETS, AUDITS AND ACCOUNTING

8.1 Approved Annual Budgets.

(a) Owner and the Westlake Parties acknowledge that they have agreed upon an Approved Annual Budget consistent with the Accounting Procedures for the period commencing on the date of this Agreement and ending December 31, 2014 (the “First Approved Annual Budget”).

(b) The Westlake Parties shall prepare and deliver to Owner, no later than 30 days before the commencement of each Fiscal Year, a proposed budget for the Shared Services and the Operating Services to be performed by the Westlake Parties and the Seconded Employees, respectively, during such Fiscal Year. Each such budget shall be prepared on the same basis and using the same methodology as the First Approved Annual Budget. Such budgets shall be prepared in sufficient detail to satisfy the reasonable requirements of Owner. However, at a minimum, such budgets shall include estimates of the labor expense and expenses incurred by employees of the Westlake Parties or their Affiliates in performing the Shared Services and the Operating Services as well as an itemized list of estimated third Person expenses to be incurred in performing the Shared Services and the Operating Services, in each case consistent with the Accounting Procedures. If requested by Owner, the Westlake Parties shall also prepare and deliver to Owner an explanation of any specific Expenditure. The Parties shall use good faith efforts to agree upon an Approved Annual Budget reasonably acceptable to Owner no later than 15 days prior to the commencement of the Fiscal Year for which such budget applies. Owner shall have the right to reasonably comment on and make objections to each annual budget proposed by the Westlake Parties, to the extent such comments and objections are with respect to the failure to prepare such budget on the same basis and using the same methodology as the First Annual Approved Budget; provided that if Owner and the Westlake Parties fail to agree on such budget, the Westlake Parties’ budget shall provisionally constitute an Annual Approved Budget. If the Parties have not reached agreement on the annual budget within 30 days after Owner’s notice of objection thereto, then senior management representatives of the Parties shall engage in negotiations, and if the Parties have not reached agreement within 30 days after commencement of negotiations, either Party shall have the right to resolve such dispute in a court of law pursuant to this Agreement. If any such dispute is resolved in favor of Owner, the Westlake Parties shall reimburse Owner the amount of Expenditures determined not to be chargeable to the Westlake Parties, with interest as provided in Section 10.1(c). As to each Approved Annual Budget, no later than the 15th day preceding the commencement of the second, third and fourth quarterly periods covered by such Approved Annual Budget, the Westlake Parties will provide to Owner adjustments to such Approved Annual Budget to reflect the estimated Expenditures to be incurred in the performance of the Shared Services and the Operating Services over the balance of the Fiscal Year covered by such Approved Annual Budget.

(c) It is acknowledged and agreed by the Parties that the annual budgeting process, the quarterly updates to such budgets, and the revisions of such budgets pursuant to this Article VIII to cover overages are for planning purposes, and if the actual Expenditures incurred by the Westlake Parties in the performance of the Shared Services and the Operating Services exceed such budgeted Expenditures, the Westlake Parties shall nevertheless be entitled to reimbursement of such actual Expenditures pursuant and subject to the terms of Article X.

8.2 Unbudgeted Expenditures. The Westlake Parties shall notify Owner as soon as practicable of any occurrences or other circumstances which the Westlake Parties have reason to believe may (a) cause any line item in the most recently Approved Annual Budget (as updated pursuant to Section 8.1) to be exceeded by the greater of (i) twenty percent (20%); or (ii) 1 million US dollars or (b) cause the total amount of such Approved Annual Budget to be exceeded by the greater of (i) twenty percent (20%); or (ii) 1 million US dollars. If the Westlake Parties determine that either clause (a) or (b) will likely occur, the Westlake Parties shall in the notice advising Owner describe the circumstances thereof in writing in such detail as may reasonably be necessary to provide an informed understanding of the situation including a description of the category or categories of Expenditures involved, the reason for such projected overage, the necessary revisions to the Approved Annual Budget to cover such overage, and such further information as Owner may reasonably request. Owner shall have the right, acting reasonably, to comment on and make objections to such revisions; provided that if Owner and the Westlake Parties fail to agree on such revisions, the Westlake Parties’ revisions shall remain in place, subject to Owner’s right to resolve disputes in a court of law pursuant to this Agreement.

8.3 Accounting, Reimbursement and Fee.

(a) The Westlake Parties shall keep a full and complete account of all Expenditures incurred by them in connection with the performance of the Shared Services and the Operating Services in the manner set forth in the Accounting Procedures, and shall otherwise keep a full and complete account of all accounts that Owner is required to maintain (except accounts required for Owner’s investors), or that are otherwise contemplated, under this Agreement.

(b) The Westlake Parties shall be reimbursed by Owner for Expenditures and Capital Expenditures incurred by the Westlake Parties in the performance of the Shared Services and the Operating Services, in accordance with the Accounting Procedures; provided, Owner shall not be required to reimburse the Westlake Parties for (i) Expenditures arising out of claims for non-payment of any and all contributions, withholding deductions or taxes measured by the wages, salaries or compensation paid to Persons employed by the Westlake Parties or any of their Affiliates in connection herewith or (ii) Expenditures for which the Westlake Parties are required to provide indemnification to Owner pursuant to Section 15.1.

8.4 Reports. The Westlake Parties shall cause to be timely prepared and delivered to Owner such reports, forecasts, implementation plans, plans of action, studies and other information pertaining to the performance of the Shared Services and the Operating Services as Owner may reasonably request from time to time. The costs incurred by the Westlake Parties in preparing and delivering such reports, forecasts, plans, studies and other information shall be included in the Expenditures to be reimbursed by Owner pursuant to Sections 8.3(b).

8.5 Audit and Examination.

(a) To the extent necessary to verify the accuracy of any statement, invoice, charge or computation made under this Agreement, each Party shall have the right, at its cost, to interview representatives of the other Party and to examine the books and records maintained by such other Party relating to this Agreement, including support for costs charged by the Party’s third party contractors, relating to the performance of the relevant Services, during normal business hours and upon reasonable notice to the other Party; provided that each Party has the right to redact from the records subject to examination of any portions thereof as necessary to comply with such Party’s confidentiality obligations. Such audit must be commenced within 12 Months of receiving said statement, invoice, charge or computation made under this Agreement and will take place at a location mutually agreeable to the Parties. All records subject to audit hereunder shall be caused to be retained for no less than two calendar years after their creation. If any such examination establishes any inaccuracy in any billing made prior to such examination, the necessary adjustments to such ▇▇▇▇▇▇▇▇ will be made promptly without any interest charge.

(b) Absent fraud or intentional concealment or misrepresentation by the relevant Party, such Party shall neither be required nor permitted to adjust any Expenditure incurred by such Party during a Fiscal Year unless a claim therefor is presented or adjustment is initiated within the 12 Months following such Fiscal Year, and in the absence of such timely claims or adjustments, the books and records rendered by the Westlake Parties shall be conclusively established as correct. If a Party has commenced an audit within the period referenced in Section 8.5(a) but has been unable to complete the audit within such period despite its good faith efforts to do so, then such Party may request a reasonable extension of time to complete the audit and such request will not be unreasonably denied by the other Party.

PAYMENT OF COSTS

10.1 Payments.

(a) Each Party shall issue to the other Party an invoice on or before the 20^th day of each Month (the “Monthly Invoice”) reflecting such other Party’s allocable share of Expenditures (split between Operating Expenses and Capital Expenditures) incurred by the Party under this Agreement in the provision of Services for the prior Month (the “Relevant Month”).

(b) Each Party shall pay the amount of each Monthly Invoice to the other Party, other than any amount thereof that is disputed in accordance with Section 10.1(e) below, not later than the 5^th day following receipt from such other Party of the Monthly Invoice. If the due date for payment is not a Business Day, then the due date for payment shall be the immediately succeeding Business Day. Any adjustments necessary to reconcile the resolution of a disputed amount with the amount actually paid shall be paid within five Days following resolution of the disputed amount. Any adjustments, whether for overpayment or underpayment, for disputed amounts shall bear interest at the Base Rate from the date of overpayment or underpayment, as the case may be, until the actual date of payment.

(c) In the event that any amount reflected in any statement or invoice is not paid when due, other than any amount thereof that is disputed in accordance with Section 10.1(e) below, such unpaid amount shall bear interest from and including the day following the due date therefor up to and including the date when payment is made, at the Default Rate.

(d) If any Party fails to make payment of any amount of any Monthly Invoice, other than any amount thereof that is disputed in accordance with Section 10.1(e) below, on or before the later of (i) the 60^th day after such payment is due an (ii) the 30^th day after notice to such Party of non-payment, the other Party shall have the right to suspend the performance of the relevant Services hereunder to such Party until such payment is made.

(e) A Party may withhold payment of all or any portion of any amount reflected as owing by the other Party in any statement or invoice received from the other Party to the extent that the paying Party disputes payment of such amount or such portion thereof in good faith. For the avoidance of doubt, as to any Monthly Invoice, a Party may withhold payment as to any disputed amount, including to account for any credit such Party believes it is owed with respect to the performance or receipt of Services, or the failure thereof. In the event of such a dispute, the disputing Party shall promptly notify the other Party, stating its reasons for disputing such amount and, to the extent available providing reasonable supporting documentation therefor.

(f) A Party may dispute a Monthly Invoice, or any portion thereof, by notice to the other Party, up to one calendar year following receipt of such Monthly Invoice, provided that if a Party fails to deliver such notification within such period, it shall be deemed to have waived the right to dispute the applicable Monthly Invoice.

(g) All payments pursuant to this Section 10.1 shall be calculated in accordance with the Accounting Principles and shall exclude any costs or expenses for which a Party is required to indemnify the other Party pursuant to Section 15.1.

(h) Monthly Invoices shall take into account any prior payments made by a Party that have not been used by the Party providing services. Each Monthly Invoice shall include a reconciliation (split between Operating Expenses and Capital Expenditures) of the Monthly Invoice payment made by the relevant Party for the Month and such Party’s allocable share of the actual Expenditures incurred by the Party providing the services during such Month, and any amount owing by one Party to the other Party pursuant to such reconciliation shall adjust the amount otherwise payable on that Monthly Invoice.

(i) All payments under this Agreement shall be made in United States dollars by wire transfer in immediately available funds by deposit to the bank account designated in writing by the Party receiving the payment. Any wire transfer charges shall be for the account of the Party making the payment. If a Party elects to change the bank or account to which payments are to be made, that Party shall notify the other Party before the effective date of such change.

10.2 Reimbursement for Emergencies.

(a) If the Westlake Parties take any action pursuant to an Emergency involving or related to the Common Facilities or the Ethylene Assets, the Westlake Parties shall be entitled to reimbursement for Owner’s allocable share of all Expenditures reasonably incurred in taking such action (subject to Section 10.2(c)). The Westlake Parties agree to promptly notify Owner of any such Emergency, and to provide Owner with sufficient

explanation and justification for any action taken in response thereto and the Expenditures incurred, or expected to be incurred, in connection therewith, any further action required, and such other details as may be required for reporting to any Governmental Authority. Owner shall reimburse the Westlake Parties for Owner’s allocable share of Expenditures reasonably incurred under this Section 10.2 upon receipt of invoices, if applicable, sent by the Westlake Parties in the ordinary course after the Expenditures have been incurred and Owner is notified thereof.

(b) The Westlake Parties are hereby authorized to make immediate commitments or expenditures, without prior approval, as necessary to accomplish the following:

(i) prevent imminent escape of gas, liquids, chemicals or vapors from the Common Facilities and/or the Ethylene Assets;

(ii) prevent imminent injury to any Person arising out of the operation of the Common Facilities and/or the Ethylene Assets;

(iv) prevent imminent failure or unplanned shutdown of the Common Facilities, any Utility Service or the Ethylene Assets;

(v) restore the Common Facilities, any Utility Service and the Ethylene Assets to operating condition following an unplanned shutdown or failure; or

(vi) comply with emergency orders of any Governmental Authority arising out of the operation of the Common Facilities, the Ethylene Assets or the performance of the Services.

(c) Notwithstanding anything to the contrary, the Westlake Parties shall not be entitled to reimbursement for Expenditures made in accordance with this Section 10.2 if the circumstance giving rise to the Expenditure resulted from the Westlake Parties’ gross negligence or willful misconduct.

(d) If an Emergency or other situation requiring prompt action arises and the Westlake Parties are not reasonably responding in a prompt fashion, Owner shall have the right to take such remedial action as it deems appropriate, at Owner’s cost, and the Westlake Parties will reimburse Owner for the Westlake Parties’ allocable share of the costs incurred by Owner in connection with such remedial action; provided, if the circumstance giving rise to such remedial action resulted from the Westlake Parties’ gross negligence or willful misconduct, then the cost of such remedial action shall be borne and paid by the Westlake Parties.

ARTICLE XI

TAXES

11.1 Embedded Tax Amounts. If any portion of any payment made by a Party hereunder is to reimburse the other Party for any federal, state or local taxes or assessments, then such other Party shall cause such taxes and assessments to be paid prior to delinquency.

11.2 Income Taxes. Notwithstanding anything to the contrary, Expenditures for which a Party is entitled to reimbursement pursuant to this Agreement shall not include taxes that are measured or based on that Party’s income or franchise taxes or similar taxes, and all such income, franchise and similar taxes shall be the responsibility of that Party.

ARTICLE XII WARRANTY/CLAIMS

(b) The Indemnifying Party shall have the right to control all aspects of the response to and/or defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article XV, including correspondence and negotiation with Governmental Authorities,

17.5 Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties hereto; provided, that the Owner may not, without the prior approval of the Conflicts Committee, agree to any amendment or modification of this Agreement that, in the reasonable judgment of the GP, will adversely affect the holders of Common Units.

17.6 No Waiver.

17.7 Safety Regulations. All employees of each Party when on the property of the other Party will conform to the rules, regulations and procedures concerning safety of such other Party. From time to time, each Party shall furnish the other Party with complete, accurate and current copies of all such rules, regulations and procedures.

17.8 Relationship of Parties. This Agreement does not create a partnership, joint venture, or relationship of trust or agency between the Parties.

17.9 Governing Law. This Agreement shall be subject to and governed by the laws of the State of Texas, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of another state. Each of the Parties hereby agrees: (i) to submit to the exclusive jurisdiction of any state or federal court sitting in Houston, Texas in any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, (ii) that all claims in respect of any such action or proceeding may be heard and determined in any such court, (iii) that such Party will not bring any action or proceeding arising out of or relating to this Agreement in any other court, and (iv) that such Party waives any defense of inconvenient forum to the maintenance of any such action or proceeding, and waives any bond, surety or other security that might be required of any other Party with respect to any such action or proceeding.

17.10 Dispute Resolution.

(a) The dispute resolution provisions set forth in this Section 17.10 shall be the final, binding and exclusive means to resolve all disputes, controversies or claims (each, a “Dispute”) arising under the Agreement, and each Party irrevocably waives any right to any trial by jury with respect to any dispute arising under this Agreement.

(b) If a dispute arises, the following procedures shall be implemented:

(i) Any Party may at any time invoke the dispute resolution procedures set forth in this Section 17.10 as to any dispute by providing written notice of such action to the other Parties.

(ii) Notwithstanding the existence of any dispute or the pendency of any procedures pursuant to this Section 17.10, and subject to Section 17.3, the Parties agree and undertake that all payments not in dispute shall continue to be made and that all obligations not in dispute shall continue to be performed.

(iii) Within 30 days after receipt of notice of a dispute, representatives of the Parties shall engage in non-binding mediation, and a specific timetable and completion date for its implementation shall also be agreed upon. If the completion date therefor shall occur without the Parties having resolved the dispute, then the Parties shall proceed under subsection (b)(iv).

The AAA shall select one (1) arbitrator. Each Party shall bear its own expenses incurred in connection with arbitration and the fees and expenses of the arbitrator shall be shared equally by the Parties involved in the dispute and advanced by them from time to time as require. It is the mutual intention and desire of the Parties that the arbitrator be selected as expeditiously as possible following the submission of the dispute to arbitration. Once the arbitrator is selected and except as may otherwise be agreed in writing by the Parties involved in such dispute or as ordered by the arbitrator upon substantial justification shown, the hearing for the dispute will be held within sixty (60) days of submission of the dispute to arbitration. The arbitrator shall render his final award within sixty (60) days, subject to extension by the arbitrator upon substantial justification shown of extraordinary circumstances, following conclusion of the hearing and any required post-hearing briefing or other proceedings ordered by the arbitrator. Any discovery in connection with arbitration hereunder shall be limited to information directly relevant to the controversy or claim in arbitration. The decision of the arbitrator in any such proceeding will be reasoned, final and binding and final judgment may be entered upon such an award in any court of competent jurisdiction, but entry of such judgment will not be required to make such award effective. Any action against any Party ancillary to arbitration (as determined by the arbitrators), including any action for provisional or conservatory measures or action to enforce an arbitration award or any judgment entered by any court in respect of any thereof may be brought in any federal or state court of competent jurisdiction located within the State of Texas, and the Parties hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of Texas over any such action. The Parties hereby irrevocably waive, to the fullest extent permitted by Law, any objection which they may now or hereafter have to the laying of venue of any such action brought in such court or any defense of inconvenient forum for the maintenance of such action. Each of the Parties agrees that a judgment in any such action may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

17.11 Waiver of Consequential Damages. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, NO PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR OR IN RESPECT OF ANY CONSEQUENTIAL LOSS OR DAMAGE, SPECIAL OR PUNITIVE DAMAGES OR LOSS OF PROFITS OR BUSINESS INTERRUPTION, SUFFERED OR INCURRED BY ANY OTHER PARTY ARISING OUT OF, IN CONNECTION WITH, OR RESULTING FROM, THIS AGREEMENT, WHETHER ANY CLAIM FOR SUCH LOSS OR DAMAGE IS BASED ON TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, CONTRACT (INCLUDING BREACH OF OR FAILURE TO PERFORM THIS AGREEMENT OR THE BREACH OF ANY REPRESENTATION OR WARRANTY HEREUNDER, WHETHER EXPRESS OR IMPLIED) OR OTHERWISE, EXCEPT FOR ANY SUCH DAMAGES RECOVERED BY ANY THIRD PARTY AGAINST ANY PARTY IN RESPECT OF WHICH SUCH PARTY WOULD OTHERWISE BE ENTITLED TO INDEMNIFICATION PURSUANT TO ARTICLE XV, PROVIDED THAT NO PARTY SHALL BE ENTITLED TO INDEMNIFICATION FOR ANY DAMAGES THAT ARE CONTRARY TO APPLICABLE LAW.

17.12 Further Assurances. In connection with this Agreement and all transactions contemplated by this Agreement, each signatory party hereto agrees to execute and deliver such additional documents and instruments and to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of this Agreement and all such transactions.
