MASTER TRANSITION SERVICES AGREEMENT

Master Transition Services Agreement, dated as of January 14, 2014 (this “Agreement”), by and between ONEOK, INC. (“Parent”) and ONE GAS, INC. (“Spinco”). All the capitalized terms used in this Agreement shall have the meaning either given those terms or incorporated by reference in the Glossary attached as Exhibit B.

R E C I T A L S:

On the Effective Date, Parent will distribute to its shareholders pro rata all of the outstanding stock of Spinco (the “Distribution”), a corporation that Parent currently owns and controls.

Incident to the Distribution, the Companies plan to disaggregate various shared services and certain common uses of facilities and equipment. In order to facilitate separation of the Companies on the Effective Date, the Companies have agreed that certain shared services and certain common uses of facilities and equipment should continue for a transitional period after the Effective Date (together such shared services and common uses are referred to as the “Transition Services”).

The Provider of the Transition Services and the Purchaser of Transition Services shall agree in a separate Schedule to this Agreement (“Schedule”) upon the general description of each particular Transition Service to be provided, the length of time the Transition Service will be provided (if less than the Term of this Agreement), the fee for the Transition Service and, if necessary, any special terms and conditions as may be applicable to the particular Transition Service. Each of the Transition Services so scheduled shall be provided under the terms and conditions set forth in this Agreement. The form of the Schedules shall be substantially as set forth in Exhibit A.

Now, therefore, in consideration of the mutual promises and agreements set forth herein, the Parties hereto hereby agree as follows:

ARTICLE I

SERVICES

Section 1.1 Initial Services. Subject to the terms, conditions, covenants and agreements contained herein, each Provider agrees to provide, or cause to be provided, to each Purchaser the services set forth on the attached Schedules (the “Initial Services”) to the scope, extent and quality that these Initial Services were provided to or within the Business prior to the Effective Date and the Purchaser agrees to compensate the Provider for the Initial Services at the amount designated on the Schedules. At any time, the Purchaser may, upon written notice of at least thirty (30) days, amend or terminate a Schedule to reduce any or all of the Initial Services to be provided by the Provider under the attached Schedules. Initial Services are further described and set forth in the attached Schedules.

Section 1.2 Company Groups; Use of Third Parties. If prior to the Effective Date the Provider had all or a portion of the Transition Services performed by a member of the Provider’s Group, or a Third Party, the Provider may cause such Transition Service to continue to be provided by a member of the Provider Group or by such Third Party. Notwithstanding the foregoing, the Provider shall remain responsible, in accordance with the terms of this Agreement, for the performance of any Transition Service it causes to be provided by a member of the Provider Group or by a Third Party. In addition, upon prior written consent of the Purchaser, which consent shall not be unreasonably withheld, the Provider may, but shall not have the obligation to, engage one or more Third Parties to perform any of the Transition Services, even if said services were traditionally performed by the Provider or a member of the Provider Group prior to the Effective Date.

Section 1.3 Omitted Services; Additional Services; Modified Services.

(a) If, within the first six (6) months after the Effective Date, either of the Companies identifies a service that reasonably should have been included in the Transition Services, but was inadvertently omitted (“Omitted Services”), then that Company may request the Company that would have been the Provider of such Omitted Services to furnish such services as Transition Services. The Provider shall be obligated to perform, at charges established pursuant to Section 2.1 hereof, any Omitted Service that was provided by the Provider to or within the Business immediately prior to the Effective Date and that the Purchaser reasonably believes is necessary to effectuate an orderly transition of the Separation of the Business under the Separation Agreement; provided, however, that the Provider shall not be required to provide any Omitted Service that the Provider reasonably believes would be commercially unreasonable. If the Provider reasonably believes the performance of any requested Omitted Service would be commercially unreasonable, the Provider and the Purchaser shall negotiate in good faith to establish terms under which the Provider can provide some or all of the Omitted Service, but the Provider shall not be obligated to provide such requested Omitted Services if, following good faith negotiation, it is unable to reach agreement with the Purchaser.

(b) The Companies may also identify additional services (“Additional Services”) that are not Omitted Services that one Party needs from the other Party to conduct its Business. The Companies shall negotiate in good faith to enter into a Schedule for each requested Additional Service setting forth a description of the Additional Service, the duration of the Additional Service, the fee for the Additional Service, and any other applicable terms. The Parties may, but shall not be required to, agree on Additional Services during the term of this Agreement.

(c) If a Purchaser requests a modification in any Transition Service (“Modified Services”), the Purchaser shall make its request to the Provider in writing. Upon the Provider’s receipt of a written request for Modified Services, the Provider shall evaluate such request and develop changes in the cost-based rates for those Transition Services as described in Section 2.1. If the Provider and the Purchaser agree to the Modified Services, the Modified Services shall be set forth in a revised Schedule which shall be signed by the Provider and the Purchaser. A requested increase in the term of a particular Transition Service shall also be deemed to be a “Modified Service.”

2

Section 1.4 Performance of Services. The Provider shall perform its duties and discharge its obligations under this Agreement in a commercially reasonable manner based upon its current practices in providing similar services for itself or its Affiliates (or prior practices in the absence of a current practice) and in accordance with any service levels and performance obligations specified in the applicable Schedule. This obligation is subject to and upon the following conditions:

(a) Except as set forth otherwise in an applicable Schedule, the Transition Services will be available only for purposes of conducting the Business of the Purchaser substantially in the manner it was conducted for the Business prior to the Effective Date.

(b) No Provider shall be required to perform any Transition Service in a manner that would (i) constitute a violation of applicable Law, (ii) would result in the breach of any software license or other applicable Contract in effect on the date of this Agreement, or (iii) violate, infringe, or constitute an infringement or misappropriation of, any Intellectual Property rights of any Third Party.

(c) No Provider shall be required to perform, and the Purchaser shall not sell, transfer, assign or otherwise use the Transition Services, in whole or in part, for the benefit of any Third Party.

(d) Except as set forth otherwise in an applicable Schedule, no Provider shall be obligated to (i) maintain the employment of any specific employee, or hire or train additional employees, (ii) purchase, lease or license any additional equipment or software or (iii) pay any cost or expend any capital related to the transfer or conversion of Information to the Purchaser upon termination of the Transition Services. In addition, no Provider shall be obligated to upgrade, update, improve, tweak, enhance, modify, add or delete any software, hardware, equipment, databases or interfaces in connection with the Transition Services.

(e) No Provider shall be required to provide any Transition Service to the extent the performance of such Transition Service becomes commercially unreasonable as a result of a cause or causes outside the reasonable control of the Provider, including unfeasible technological requirements or an event of Force Majeure as set forth in Section 8.3 herein.

Section 1.5 Changes to Services. Except as provided in Section 1.8 below, the Provider may make changes from time to time in the manner of performing the Transition Services, if:

(a) The Provider is making similar changes in performing similar services for itself or its Affiliates;

(b) The Provider furnishes to the Purchaser substantially the same notice (in content and timing) and right of consultation as the Provider shall furnish to its Affiliates respecting such changes, provided that if there is no such notice or right of consultation, then the Provider shall give a commercially reasonable notice and right of consultation to the Purchaser; and

3

(c) changes shall not result in any material degradation of the Transition Services and after the applicable changes, the Transition Services shall meet the standards imposed by this Agreement.

Section 1.6 Mutual Cooperation; Use of Existing Resources. The Purchaser and the Provider shall cooperate with each other in connection with the performance of the Transition Services, including producing on a timely basis all Information that is reasonably requested with respect to the performance of the Transition Services. The Provider may need to rely upon the expertise of and have access to certain employees of the Purchaser. Accordingly, as may be reasonably necessary to perform the Transition Services, the Provider shall be entitled to have reasonable access to any employee of the Purchaser to the extent necessary to perform the Transition Services.

Section 1.7 Internal Controls, Record Retention and Operating Policies. The Provider shall maintain and comply with the internal controls, record retention policies and other operating policies and procedures that were in place prior to the Effective Date with respect to each Transition Service or as otherwise implemented by the Parties to comply with internal standards and procedures or applicable law. If the Purchaser under a Schedule requires a change to the internal controls or compliance policies or requires the implementation of additional internal controls or compliance policies related to a Transition Service in order to comply with changes to applicable Law or internal standards and procedures, the Provider shall use commercially reasonable efforts to change or add to the internal controls or compliance policies related to the Transition Service as requested by the Purchaser. In connection with a Provider changing or adding to internal controls or compliance policies as required by the foregoing, the Purchaser shall pay for any additional costs for the Transition Service associated with the implementation or maintenance of the applicable change or addition; provided, however, that if (i) such change or addition is required for the compliance of both the Purchaser and the Provider with a Law or policy applicable to both, or (ii) both the Purchaser and the Provider will benefit from such change or addition, the Parties shall negotiate in good faith an equitable sharing of the costs associated with such change or addition.

Section 1.8 Audit Assistance. The Provider and the Purchaser shall cooperate with the other in providing such Information as may be required and access for audits by independent certified public accountants, internal auditors, regulators, or other persons with the right of audit. A Party acting as a Purchaser hereunder may, at its sole cost and expense, request its third party auditor to perform a SAS 70 Type II audit or other audit or review of such Provider’s internal controls and operating environment related to the Transition Services upon reasonable advance notice, and the Provider shall perform such an audit or review or assist the Purchaser or the Purchaser’s third party auditor in connection with such an audit or review, in each case at the Purchaser’s expense. At the conclusion of such audit or review, the Provider shall implement such reasonable changes to the Transition Services or operating environment to correct deficiencies identified in the audit report to ensure compliance with applicable law or that are otherwise necessary for the Provider to comply with the Purchaser’s internal policies in connection with the Transition Services. To the extent such changes are required for the benefit of both Parties, the Parties shall share the costs to implement all such changes equally. To the extent such changes are required solely for the benefit of the Purchaser, including but not limited to changes required to comply with the Purchaser’s internal policies, the Purchaser shall pay all costs to implement such changes. All incremental costs incurred by a Company in providing such Information or assistance to the other Company shall be reimbursed by such other Company.

ARTICLE II

CHARGES AND BILLING; TAXES

Section 2.1 Charges for Transition Services.

(a) It is the intent of the Parties that the Transition Services are provided by the Provider at the Provider’s actual cost without any element of profit. The fee for the Transition Services is determined based upon the actual direct costs of providing the Transition Services internally, which actual direct costs include but are not limited to the prorated wages and employee benefits of employees plus payroll taxes, at the Provider, plus reimbursement of out-of-pocket Third Party costs and expenses. The rates provided on the attached Schedules represent the Parties’ current estimate of the actual costs, but such rates are subject to adjustment to reflect actual costs or as otherwise set forth in Section 2.1(b).

(b) If events or circumstances arise which materially increase or decrease the cost of providing Transition Services based upon the methodology for charges provided in Section 2.1(a), then upon thirty (30) days prior written notice to the Purchaser, the cost shall be equitably adjusted to take into account the changed events or circumstances so that the rates are adjusted to reflect the actual direct costs of the Provider, plus out-of-pocket Third Party costs and expenses. Rates for a Transition Service will also be adjusted whenever the cost of providing the Transition Service increases or decreases due to the renegotiation of a software license or obtaining a new software license as a result of a change in the relationship between the Provider and a software licensor; provided, however, that in no event shall the Purchaser be charged for (i) the license of new software, or (ii) upgrades or modifications to existing software made or purchased by the Provider to the extent such new license, upgrade or modification was not necessary for the provision of the Transition Services, unless specifically requested and agreed to by the Companies as set forth in Section 1.3(c). The Parties agree to meet periodically to review and, if necessary, adjust the rates in order to bring the rates into conformity with the criteria of Section 2.1(a).

(c) Unless otherwise previously adjusted in accordance with Section 2.1(b), for so long as this Agreement is still in effect, specific rates for Transition Services shall be subject to adjustment as of January 1 in each year, commencing January 1, 2015, in order to bring the rates into conformity with the criteria of Section 2.1(a).

(d) If a Purchaser requests modifications to the Transition Services under Section 1.3(c), the Provider shall determine appropriate changes in the charges for the Modified Services in accordance with the methodology set forth in Section 2.1(a) and shall give written notice to the Purchaser of such changes. If the Modified Services require the hiring of additional employees or the procurement of additional software, equipment or services, the Provider may include in the charges for the Modified Services provisions for the recovery of (i) employee hiring expenses, and (ii) the cost of procuring additional software, equipment and services. In case any Modified Service requires the incurrence of costs to implement the modification, the Provider may charge the Purchaser for such costs on an “up front” basis, in addition to the periodic rates charged for the Modified Service.

5

Section 2.2 Payment Terms. The Provider shall bill all charges for Transition Services on a monthly basis. The Purchaser shall pay the Provider for all Transition Services within thirty (30) days of receipt of an invoice. Late payments shall bear interest at the lesser of twelve percent (12%) per annum or the maximum non-usurious rate of interest permitted by applicable law.

Section 2.3 Taxes. The Purchaser shall pay any and all Transfer Taxes incurred in connection with the applicable Provider’s provision of the Transition Services. In the event that applicable Law requires that an amount in respect of any Taxes be withheld from any payment by the Purchaser (or the applicable Affiliate of the Purchaser) to the Provider (or its applicable Affiliate) under this Agreement (other than Taxes imposed or based on net income or gross receipts) the amount payable to the Provider (or its applicable Affiliate) shall be increased as necessary so that, after the Purchaser (or the applicable Affiliate of the Purchaser) has withheld amounts required by applicable Law, the Provider (or its applicable Affiliate) receives an amount equal to the amount it would have received had no such withholding been required, and the Purchaser (or the applicable affiliate of the Purchaser) shall withhold such Taxes and pay such withheld amounts over to the applicable taxing authority in accordance with the requirements of the applicable law and provide the Provider (or its applicable Affiliate) with a receipt confirming such payment. The Provider shall reasonably cooperate with the Purchaser to determine whether any such deduction or withholding applies to the Transitional Services, and if so, shall further reasonably cooperate to minimize applicable withholding taxes.

Section 2.4 Record-Keeping. The Provider shall maintain complete and accurate records of any invoices and supporting documentation for all amounts billed to, and payments made by, the Purchaser under this Agreement, subject to the Provider’s usual record retention policies. The Provider shall provide to the Purchaser or its designee documentation and other information relating to each invoice as may be reasonably requested by the Purchaser to verify that the Provider’s charges are accurate, complete, and valid in accordance with this Agreement.

Section 2.5 No Set-Off. The Purchaser’s obligation to make any required payments under this Agreement shall not be subject to any unilateral right of offset, set-off, deduction or counterclaim, however arising.

Section 2.6 Disputed Charges. If the Purchaser disputes a charge in good faith, it may withhold payment of such charge so long as the Purchaser makes timely payment of all undisputed charges and, no later than the payment deadline, provides the Provider with a detailed written explanation of the reasons for the Purchaser’s dispute of the charge. The Parties shall cooperate to promptly resolve any disputed charge. If the Parties agree that the disputed charge is not a valid charge, the Provider shall either (i) include a credit within the next invoicing cycle (to the extent the Purchaser previously paid the disputed charge) or (ii) promptly issue an amended invoice. If the Parties agree that the disputed charge is a valid charge, the Purchaser shall pay the charge within fifteen (15) days from the date of the resolution of the dispute. If the Parties are unable to come to a resolution on the disputed charge within thirty (30) days, then the dispute shall be referred to senior management of each Party.

ARTICLE III

TERM AND TERMINATION

Section 3.1 Term. Unless otherwise terminated pursuant to Section 3.2, and except as provided in Section 8.1, this Agreement shall terminate with respect to any Transition Service the later of (i) twelve (12) months from the Effective Date; or (ii) at the close of business on the last day of the Service Period for such Transition Service designated in the applicable Schedule if longer than twelve (12) months (the “Term”). Notwithstanding the foregoing, the Companies may elect to extend the Service Period for any Transition Service upon mutual written agreement.

Section 3.2 Early Termination.

(a) The Purchaser shall have the right at any time during the Term of this Agreement to terminate its obligation to purchase any Transition Service for future months, effective on the first day of the applicable month, upon the giving of an advance written notice to the Provider of not less than thirty (30) days prior to the effective date of termination. If the Purchaser terminates a Transition Service prior to the expiration of the Service Period for such Transition Service, the fees for any remaining months of the Service Period for associated Transition Services shall be decreased to account for the Transition Services that are terminated and any prepaid monthly charges shall be refunded to the Purchaser. Upon early termination of Transition Services under this Section, the Purchaser shall pay the Provider for any unreimbursed costs that directly result from the early termination and for any incurred fees or expenses being amortized over the Service Period.

(b) In addition, the Purchaser shall have the right at any time during the Term of this Agreement to terminate its obligations to purchase any Transition Service if the Provider materially breaches a provision with respect to any particular Transition Service and, if curable, does not cure such breach within thirty (30) days after being given written notice of such breach. Upon termination for breach, the Purchaser shall not be obligated to pay a termination fee and any prepaid charges shall be prorated and the unused portion refunded to the Purchaser.

(c) The Provider shall have the right at any time during the Term of this Agreement to terminate its obligation to provide any Transition Service if the Purchaser materially breaches a provision with respect to any particular Transition Service and, if curable, does not cure such breach within 30 days after being given written notice of such breach. For the avoidance of doubt, failure to timely pay money shall be a material breach.

Section 3.3 Data Migration. On or prior to the last day of each relevant Service Period, the Provider shall use commercially reasonable efforts to support any transfer of Information concerning the relevant Transition Services to the applicable Purchaser. If requested by the Purchaser, the Provider shall deliver to the Purchaser, within such time periods as the Provider and the Purchaser may reasonably agree, all Information received, generated or computed for the benefit of such Purchaser during the Service Period, in electronic and/or hard copy form; provided that (a) the Provider shall not have any obligation to provide or cause to be provided Information in any non-standard format, and (b) the Provider shall be reimbursed for its reasonable out-of-pocket costs of providing Information in any format other than its standard format, unless otherwise expressly provided in the applicable Schedule.

ARTICLE IV

CONFIDENTIALITY

Section 4.1 Protection of Information. The Provider and the Purchaser may share Information that is confidential or subject to privacy laws in the course of the Provider performing Transition Services. The Provider and the Purchaser shall each protect and maintain the confidentiality of all Information provided to it by the other Party that is either designated as “confidential” by clearly so marking on or in the transmittal in a manner that may be easily observed, is required to be kept confidential under law, or contains financial or proprietary data (“Confidential Information”). The Provider and the Purchaser shall each use, as applicable, (a) in the absence of a policy or procedure used to provide substantially the same service before the Effective Date, the same internal policies and controls to protect and maintain the other’s Confidential Information as are used to protect their own Confidential Information or (b) those policies and procedures that were in effect prior to the Effective Date and used by the Provider in providing substantially the same service to the Purchaser. The Provider and the Purchaser shall use the other’s Confidential Information only as required for the purposes of this Agreement and shall return upon request, subject to the limitations of Section 3.3, or destroy Confidential Information that is no longer needed to render Transition Services in accordance with the receiving Party’s retention policies; provided that the receiving Party has been provided prior written notice of such retention policies.

Section 4.2 Exclusion of Certain Information. The provisions of Section 4.1 do not apply to Information that (i) was, is or becomes generally available to the public other than as a result of a breach of Section 4.1 or any applicable confidentiality agreement by the receiving Party or its representatives; (ii) was or is developed by the receiving Party independently of and without reference to any Confidential Information of the disclosing Party; or (iii) was, is or becomes available to the receiving Party on a non-confidential basis from a Third Party not bound by a confidentiality agreement. For the purposes of this Article IV, “receiving Party” means the Party receiving the Confidential Information of the other Party.

ARTICLE V
