WHEREAS , all acts and requirements necessary to make this Supplemental Indenture a legal, valid and binding obligation of the Company and the Guarantors have been done; and

NOW THEREFORE , in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Guarantor hereby guarantees the Company’s obligations under the Currently Outstanding Securities as follows:

ARTICLE I

RELATION TO INDENTURE; DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

Section 1.01 Relation to Indenture . With respect to the Currently Outstanding Securities, this Supplemental Indenture constitutes an integral part of the Indenture.

Section 1.02 Definitions . For all purposes of this Supplemental Indenture, capitalized terms used herein and not otherwise defined herein shall have the meanings assigned thereto in the Original Indenture.

Section 1.03 General References . All references in this Supplemental Indenture to Articles and Sections, unless otherwise specified, refer to the corresponding Articles and Sections of this Supplemental Indenture; and the term “herein”, “hereof”, “hereunder” and any other word of similar import refers to this Supplemental Indenture.

ARTICLE II

AGREEMENT TO GUARANTEE

Section 2.01 Unconditional Guarantee .

(a) For value received, subject to Section 2.04 hereof, each of the Guarantors hereby fully, irrevocably, unconditionally and absolutely guarantees to the Holders of each series of Currently Outstanding Securities and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on such Currently Outstanding Securities, and all other amounts due and payable under the Indenture and such Currently Outstanding Securities by the Company to the Trustee or such Holders (including, without limitation, all costs and expenses (including reasonable legal fees and disbursements) incurred by the Trustee or such Holders in connection with the enforcement of the Indenture and the Guarantees) (collectively, the “ Indenture Obligations ”), when and as such amounts shall become due and payable, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, according to the terms of such Currently Outstanding Securities and the Indenture. The guarantees by the Guarantors set forth in this ARTICLE II are referred to herein as the “ Guarantees .” Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Indenture Obligations and would be owed by the Company to the Trustee or such Holders under the Indenture and such Currently Outstanding Securities but for the fact that they are unenforceable, reduced, limited, impaired, suspended or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Company.

(b) Failing payment when due of any amount guaranteed pursuant to the Guarantees, for whatever reason, each Guarantor will be obligated (to the fullest extent permitted by applicable law) to pay the same immediately to the Trustee, without set-off or counterclaim or other reduction whatsoever (whether for taxes, withholding or otherwise). The Guarantees hereunder are intended to be a general, unsecured, senior obligation of each Guarantor and will rank pari passu in right of payment with all unsecured indebtedness of such Guarantor that is not, by its terms, expressly subordinated in right of payment to the Guarantees of such Guarantor. Each Guarantor hereby agrees that, to the fullest extent permitted by applicable law, subject to Section 2.04 hereof, its obligations hereunder shall be full, irrevocable, unconditional and absolute, irrespective of the validity, regularity or enforceability of such Currently Outstanding Securities, the Guarantees or the Indenture, the absence of any action to enforce the same, any waiver or consent by any such Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of such Guarantor. Each Guarantor hereby agrees that in the event of a default in payment of any Indenture Obligations, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, legal proceedings may be instituted by the Trustee on behalf of such Holders or, subject to Section 507 of the Indenture, by such Holders, on the terms and conditions set forth in the Indenture, directly against such Guarantor to enforce the Guarantees without first proceeding against the Company.

(c) To the fullest extent permitted by applicable law, subject to Section 2.04 hereof, the obligations of each Guarantor under this ARTICLE II shall be as aforesaid full, irrevocable, unconditional and absolute and shall not be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Company or either Guarantor contained in any of such Currently Outstanding Securities or the Indenture, (ii) any impairment, modification, release or limitation of the liability of the Company, either Guarantor or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the decision of any court, (iii) the assertion or exercise by the Trustee or any such Holder of any rights or remedies under any of such Currently Outstanding Securities or the Indenture or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the purported assignment of any property as security for any of such Currently Outstanding Securities, including all or any part of the rights of the Company or either Guarantor under the Indenture, (v) the extension of the time for payment by the Company or either Guarantor of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of such Currently Outstanding Securities or the Indenture or of the time for performance by the Company or either Guarantor of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or either Guarantor set forth in the Indenture, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment, rehabilitation or relief of, or other similar proceeding affecting, the Company or either Guarantor or any of their respective assets, or the disaffirmance of any of such Currently Outstanding Securities, the Guarantees or the Indenture in any such proceeding, (viii) the release or discharge of the Company or either Guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (ix) the unenforceability of any of such Currently Outstanding Securities, the Guarantees or the Indenture, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Company or either Guarantor, or (xi) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, a surety or either Guarantor.

(d) To the fullest extent permitted by applicable law, each Guarantor hereby (i) waives diligence, presentment, demand of payment, notice of acceptance, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or such Guarantor, and all demands and notices whatsoever, (ii) acknowledges that any agreement, instrument or document evidencing the Guarantees may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Guarantees without notice to them and (iii) covenants that its Guarantees will not be discharged except by complete performance of the Guarantees. To the fullest extent permitted by applicable law, each Guarantor further agrees that if at any time all or any part of any payment theretofore applied by any Person to any Guarantees is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of either Guarantor, such Guarantees shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Guarantees shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

payments arising out of, or based upon, such right of subrogation with respect to any of such Currently Outstanding Securities until all of such Currently Outstanding Securities and the Guarantees shall have been indefeasibly paid in full or discharged.

(f) To the fullest extent permitted by applicable law, no failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, power, privilege or remedy under this ARTICLE II and the Guarantees shall operate as a waiver thereof, nor shall any single or partial exercise of any rights, power, privilege or remedy preclude any other or further exercise thereof, or the exercise of any other rights, powers, privileges or remedies. The rights and remedies herein provided for are cumulative and not exclusive of any rights or remedies provided in law or equity. Nothing contained in this ARTICLE II shall limit the right of the Trustee or the Holders to take any action to accelerate the maturity of such Currently Outstanding Securities pursuant to Article FIVE of the Indenture or to pursue any rights or remedies under the Indenture or under applicable law.

Section 2.02 Limitation on Guarantor Liability . Each Guarantor and the Trustee hereby confirms that it is the intention of all such parties that the Guarantees of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantees. To effectuate the foregoing intention, the Trustee and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of the other Guarantor in respect of the obligations of such other Guarantor under this ARTICLE II, result in the obligations of such Guarantor under its Guarantees not constituting a fraudulent transfer or conveyance.

Section 2.03 No Requirement to Endorse Notation of Guarantee . Each Guarantor hereby agrees that its execution and delivery of this Supplemental Indenture and this ARTICLE II shall evidence its Guarantee without the need for notation on any Currently Outstanding Securities.

Section 2.04 Release of Guarantee .

(a) Notwithstanding anything to the contrary in this ARTICLE II, if a Guarantor (i) shall cease to be a Subsidiary of the Company or (ii) shall no longer be (x) an obligor on, or issuer of, any capital markets debt securities or (y) a guarantor of any capital markets debt securities issued by the Company or the other Guarantor, in each case other than the Currently Outstanding Securities or any other series of capital market debt securities of the Company outstanding on, and for which such Guarantor is giving a guarantee, the date hereof, then if no Default or Event of Default shall have occurred and be continuing, such Guarantor, upon giving notice to the Trustee to the foregoing effect, shall be deemed to be released from all of its obligations under the Indenture, and the Guarantees shall be of no further force or effect with respect to such Guarantor. Following the receipt by the Trustee of any such notice, the Company shall cause the Indenture to be amended as provided in Section 901 of the Indenture; provided , however , that the failure to so amend the Indenture shall not affect the validity of the termination of the Guarantees with respect to such Guarantor.

(b) In addition, upon (i) the exercise of the legal defeasance or covenant defeasance option or the satisfaction and discharge of the Indenture as provided in ARTICLES FOURTEEN and FOUR, respectively, of the Indenture with respect to a series of Currently Outstanding Securities, or (ii) a series of Currently Outstanding Securities ceasing to be Outstanding, each of the Guarantors shall be deemed to be released from all its obligations under the Indenture with respect to such series of Currently Outstanding Securities and the Guarantees of such series of Currently Outstanding Securities shall be of no further force or effect.

GUARANTY AGREEMENT

THIS GUARANTY AGREEMENT (the “ Agreement ”), dated as of June 30, 2017 is made by ONEOK PARTNERS INTERMEDIATE LIMITED PARTNERSHIP and ONEOK PARTNERS, L.P., each a Delaware limited partnership (each a “ Guarantor ” and collectively, the “ Guarantors ”) in favor of CITIBANK, N.A., a national banking association, as administrative agent (the “ Administrative Agent ”) for the several banks and other financial institutions (the “ Lenders ”) from time to time party to the Credit Agreement dated as of April 18, 2017, by and among and ONEOK, INC. (the “ Borrower ”), the Lenders, the Administrative Agent, Citibank, N.A., as an L/C Issuer and as a Swing Line Lender, and Bank of America, N.A., as L/C Issuer and a Swing Line Lender (as amended, restated, supplemented or otherwise modified from time to time, the “ Credit Agreement ”; capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement).

W I T N E S S E T H:

WHEREAS, pursuant to the Credit Agreement, the Lenders have agreed to establish a revolving credit facility for the Borrower;

WHEREAS, each Guarantor is a direct or indirect Subsidiary of the Borrower and will derive substantial benefit from the making of Loans by the Lenders and the issuance of Letters of Credit by the L/C Issuers; and

WHEREAS, it is a condition precedent to the obligations of the Administrative Agent, the L/C Issuers, the Swing Line Lenders, and the Lenders under the Credit Agreement that each Guarantor execute and deliver to the Administrative Agent this Agreement and each Guarantor wishes to fulfill said condition precedent.

NOW, THEREFORE, in order to induce Lenders to extend the Loans and the L/C Issuers to issue Letters of Credit and to make the financial accommodations as provided for in the Credit Agreement and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1. Guarantee . Each Guarantor unconditionally guarantees, jointly with any other Guarantors from time to time and severally, as a primary obligor and not merely as a surety, the due and punctual payment and performance of all Obligations, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise and whether recovery upon such indebtedness and liabilities may be or hereafter become unenforceable or shall be an allowed or disallowed claim under any proceeding or case commenced by or against any Loan Party under Debtor Relief Laws, and including interest that accrues after the commencement by or against any Loan Party of any proceeding under any Debtor Relief Laws whether or not the claim for such interest is allowed in such proceeding, including, without limitation, (i) the due and punctual payment of (A) the principal of and premium, if any, and interest (including interest accruing during the pendency of any proceeding or case under any Debtor Relief Law, regardless of whether allowed or allowable in such proceeding or case) on the Loans, when and as due, whether at maturity, by acceleration, upon one or more dates set for prepayment or otherwise, (B) each payment required to be made by the Borrower under the Credit Agreement in respect of any Letter of Credit, when and as due, including payments in respect of reimbursement or disbursements, interest thereon and obligations to provide cash collateral, and (C) all other monetary obligations, including fees, costs, expenses and indemnities, whether primary, secondary, direct, contingent, fixed or otherwise of the Borrower and other Loan Parties to the Administrative Agent and the Lenders under the Credit Agreement and the other Loan Documents, and (ii) the due and punctual performance of all covenants, agreements, obligations and liabilities of the Borrower and other Loan Parties under or

Page 1

pursuant to the Credit Agreement and the other Loan Documents (collectively, the “ Guaranteed Obligations ”). Each Guarantor further agrees that the Guaranteed Obligations may be amended, extended, refinanced, modified or renewed, in whole or in part, without notice to or further assent from such Guarantor, and that such Guarantor will remain bound upon its guarantee notwithstanding any amendment, extension, refinancing, modification or renewal of any Guaranteed Obligations. All payments made by a Guarantor under this Agreement shall be made to the Administrative Agent at the Administrative Agent’s Office in Dollars.

Anything contained herein to the contrary notwithstanding, to the extent that the obligations of any Guarantor hereunder would be subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Code (Title 11, United States Code) or any comparable provisions of any similar federal or state law, the obligations of such Guarantor hereunder shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to such avoidance provisions.

Section 2. Obligations Not Waived . To the fullest extent permitted by applicable law, each Guarantor waives presentment or protest to, demand of or payment from the Borrower or any other guarantor of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. To the fullest extent permitted by applicable law, the obligations of each Guarantor hereunder shall not be affected by (i) the failure of the Administrative Agent or any Lender to assert any claim or demand or to enforce or exercise any right or remedy against the Borrower or any other guarantor under the provisions of the Credit Agreement, any other Loan Document or otherwise, (ii) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, this Agreement, any other Loan Document, any guarantee or any other agreement, or (iii) the failure to perfect any security interest in, or the release of, any of the security held by or on behalf of the Administrative Agent or any Lender.

Section 3. Guarantee of Payment . Each Guarantor further agrees that its guarantee constitutes a guarantee of payment when due and not of collection, and waives any right to require that any resort be had by the Administrative Agent or any Lender to any security held for payment of the Guaranteed Obligations or to any balance of any deposit account or credit on the books of the Administrative Agent or any Lender in favor of the Borrower or any other Person.

Section 4. No Discharge or Diminishment of Guarantee . The obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than the indefeasible payment in full in cash of the Guaranteed Obligations), including any claim of waiver, release, surrender, alteration, or compromise of any of the Guaranteed Obligations with respect to any other obligor, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor hereunder shall not be discharged or impaired or otherwise affected by the failure of the Administrative Agent or any Lender to assert any claim or demand or to enforce any remedy under the Credit Agreement, any other Loan Document or any other agreement, by any waiver or modification of any provision of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or omission that may or might in any manner or to any extent vary the risk of the Guarantors or that would otherwise operate as a discharge of the Guarantors as a matter of law or equity (other than the indefeasible payment in cash of the Obligations).

Section 5. Defenses of Borrower Waived . To the fullest extent permitted by applicable law, each Guarantor waives any defense based on or arising out of any defense of any Loan Party or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from

Page 2

any cause of the liability of any Loan Party, other than the final and indefeasible payment in full in cash of the Guaranteed Obligations. The Administrative Agent and the Lenders may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept an assignment of any such security in lieu of foreclosure, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any other Loan Party or any other guarantor, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Guaranteed Obligations have been finally and indefeasibly paid in cash. Pursuant to applicable law, each Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against the Borrower or any other guarantor, as the case may be, or any security.

Section 6. No Setoff or Deductions . Each Guarantor shall make all payments hereunder without setoff or counterclaim. Each Guarantor agrees to the provisions of Section 3.01 of the Credit Agreement that are applicable to such Guarantor, and such provisions are hereby incorporated by reference herein. The obligations of each Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Agreement.

Section 7. Information . Each Guarantor assumes all responsibility for being and keeping itself informed of other Loan Parties’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Administrative Agent or the Lenders will have any duty to advise any Guarantor of information known to it or any of them regarding such circumstances or risks.

Section 8. Indemnity and Subrogation . In addition to all such rights of indemnity and subrogation as the Guarantors may have under applicable law (but subject to Section 9 ), the Borrower agrees that (a) in the event a payment shall be made by a Guarantor under this Agreement, the Borrower shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment and (b) in the event any assets of a Guarantor shall be sold to satisfy a claim of any Lender under this Agreement, the Borrower shall indemnify such Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

Section 9. Subordination . Notwithstanding any provision of this Agreement to the contrary, all rights of the Guarantors against the Borrower or any other Loan Party under Section 8 and all other rights of indemnity, contribution, reimbursement or subrogation under applicable law or otherwise shall be fully subordinated and junior to the indefeasible prior payment in full in cash of the Guaranteed Obligations. No failure on the part of the Borrower to make the payments required under applicable law or otherwise shall in any respect limit the obligations and liabilities of the Guarantors with respect to its obligations hereunder, and the Guarantors shall remain liable for the full amount of the obligations of the Guarantors hereunder. In addition, all Indebtedness and other obligations of the Borrower, and all Indebtedness and other obligations of any other Loan Party, in each case now or hereafter owing to the Guarantors are hereby subordinated in right of payment to the prior indefeasible payment in full in cash of the Guaranteed Obligations. If any amount shall be paid to any Guarantor on account of (i) such subrogation, contribution, reimbursement, indemnity or similar right or (ii) any such Indebtedness or obligations of any Loan Party, such amount shall be held in trust for the benefit of the Administrative Agent and the Lenders and shall forthwith be paid to the Administrative Agent to be credited against the payment of the Guaranteed Obligations, but without reducing or affecting in any manner the liability of the Guarantors under this Guaranty; provided that payments of Indebtedness and other obligations owing

Page 3

by the Borrower or other Loan Party to the Guarantors at a time when there does not exist a Default or Event of Default shall not be held in trust or paid to the Administrative Agent.

Section 10. Representations and Warranties . Each Guarantor represents and warrants as to itself that all representations and warranties relating to it (as a Subsidiary of the Borrower) contained in the Credit Agreement are true and correct in all material respects, except that such materiality qualifier shall not apply to the extent that any such representation and warranty is qualified by materiality.

Section 11. Termination; Reinstatement . This Guaranty is a continuing and irrevocable guaranty of all Guaranteed Obligations now or hereafter existing and shall remain in full force and effect until the Guaranteed Obligations have been indefeasibly paid in full in cash, all other amounts payable under this Guaranty have been indefeasibly paid in full in cash, the Lenders have no further commitment to lend under the Credit Agreement, the Fronting Exposure has been reduced to zero and no L/C Issuer has any further obligation to issue Letters of Credit under the Credit Agreement. Notwithstanding the foregoing, this Agreement shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by any Lender or any Guarantor upon the bankruptcy or reorganization of the Borrower, any Guarantor or otherwise. The obligations of the Guarantors under this paragraph shall survive termination of this Agreement.

Section 12. Stay of Acceleration . In the event that acceleration of the time for payment of any of the Guaranteed Obligations is stayed, in connection with any case commenced by or against any Guarantor or the Borrower under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by the Guarantor immediately upon demand by the Administrative Agent, on behalf of the Lenders.

Section 13. Expenses . The Guarantors shall pay on demand all out-of-pocket expenses in any way relating to the enforcement or protection of the rights of the Administrative Agent and the Lenders under this Agreement or in respect of the Guaranteed Obligations, including any incurred during any “workout” or restructuring in respect of the Guaranteed Obligations and any incurred in the preservation, protection or enforcement of any rights of the Administrative Agent and the Lenders in any proceeding any Debtor Relief Laws. The obligations of the Guarantors under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Agreement.

Section 14. Binding Effect; Several Agreement; Assignments . Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the successors and assigns of such party; and all covenants, promises and agreements by or on behalf of the Guarantors that are contained in this Agreement shall bind the Guarantors and their respective successors and assigns and inure to the benefit of the Administrative Agent, the Lenders and their respective successors and assigns, and the Lenders may, without notice to the Guarantors and without affecting the Guarantors’ obligations hereunder, assign, sell or grant participations in the Guaranteed Obligations and this Guaranty, in whole or in part. This Agreement shall become effective as to each Guarantor when a counterpart hereof is executed on behalf of such Guarantor. No Guarantor shall have the right to assign its rights or obligations hereunder or any interest herein (and any such attempted assignment shall be void).

Section 15. Waivers; Amendment .

THIS GUARANTY AGREEMENT (the “ Agreement ”), dated as of June 30, 2017 is made by ONEOK, INC., an Oklahoma corporation (the “ Guarantor ”) in favor of MIZUHO BANK, LTD., a national banking association, as administrative agent (the “ Administrative Agent ”) for the several banks and other financial institutions (the “ Lenders ”) from time to time party to the Term Loan Agreement, dated as of January 8, 2016 (the “ Original Credit Agreement ”), as amended by the First Amendment to Term Loan Agreement, dated as of April 18, 2017 (the “ Amendment ”), each by and among ONEOK PARTNERS, L.P. (the “ Borrower ”), the Lenders and the Administrative Agent (the Original Credit Agreement, as amended by the Amendment, and as further amended, restated, supplemented or otherwise modified from time to time, the “ Credit Agreement ”; capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement).

W I T N E S S E T H:

WHEREAS, pursuant to the Credit Agreement, the Lenders established a term loan facility for the Borrower;

WHEREAS, Borrower is a direct or indirect Subsidiary of the Guarantor and Guarantor will derive substantial benefit the Lenders entering into the Amendment and amending the terms of the Original Credit Agreement; and

WHEREAS, it is a condition precedent to the effectiveness of the amendments to the Original Credit Agreement in the Amendment that Guarantor execute and deliver to the Administrative Agent this Agreement and Guarantor wishes to fulfill said condition precedent.

NOW, THEREFORE, in order to induce Lenders to enter into the Amendment and amend the Original Credit Agreement as set forth in the Amendment, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1. Guarantee . The Guarantor unconditionally guarantees, jointly with any other guarantors from time to time and severally, as a primary obligor and not merely as a surety, the due and punctual payment and performance of all Obligations, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise and whether recovery upon such indebtedness and liabilities may be or hereafter become unenforceable or shall be an allowed or disallowed claim under any proceeding or case commenced by or against any Loan Party under Debtor Relief Laws, and including interest that accrues after the commencement by or against any Loan Party of any proceeding under any Debtor Relief Laws whether or not the claim for such interest is allowed in such proceeding, including, without limitation, (i) the due and punctual payment of (A) the principal of and premium, if any, and interest (including interest accruing during the pendency of any proceeding or case under any Debtor Relief Law, regardless of whether allowed or allowable in such proceeding or case) on the Loans, when and as due, whether at maturity, by acceleration, upon one or more dates set for prepayment or otherwise, and (B) all other monetary obligations, including fees, costs, expenses and indemnities, whether primary, secondary, direct, contingent, fixed or otherwise of the Borrower and other Loan Parties to the Administrative Agent and the Lenders under the Credit Agreement and the other Loan Documents, and (ii) the due and punctual performance of all covenants, agreements, obligations and liabilities of the Borrower and other Loan Parties under or pursuant to the Credit Agreement and the other Loan Documents (collectively, the “ Guaranteed Obligations ”). The Guarantor further agrees that the Guaranteed Obligations may be amended, extended, refinanced, modified or renewed, in whole or in part, without notice to or further assent from the Guarantor, and that the Guarantor will remain bound upon its guarantee notwithstanding any amendment, extension, refinancing, modification or renewal of any

Page 1

Guaranteed Obligations. All payments made by the Guarantor under this Agreement shall be made to the Administrative Agent at the Administrative Agent’s Office in Dollars.

Anything contained herein to the contrary notwithstanding, to the extent that the obligations of the Guarantor hereunder would be subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Code (Title 11, United States Code) or any comparable provisions of any similar federal or state law, the obligations of the Guarantor hereunder shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to such avoidance provisions.

Section 2. Obligations Not Waived . To the fullest extent permitted by applicable law, the Guarantor waives presentment or protest to, demand of or payment from the Borrower or any other guarantor of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. To the fullest extent permitted by applicable law, the obligations of the Guarantor hereunder shall not be affected by (i) the failure of the Administrative Agent or any Lender to assert any claim or demand or to enforce or exercise any right or remedy against the Borrower or any other guarantor under the provisions of the Credit Agreement, any other Loan Document or otherwise, (ii) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, this Agreement, any other Loan Document, any guarantee or any other agreement, or (iii) the failure to perfect any security interest in, or the release of, any of the security held by or on behalf of the Administrative Agent or any Lender.

Section 3. Guarantee of Payment . The Guarantor further agrees that its guarantee constitutes a guarantee of payment when due and not of collection, and waives any right to require that any resort be had by the Administrative Agent or any Lender to any security held for payment of the Guaranteed Obligations or to any balance of any deposit account or credit on the books of the Administrative Agent or any Lender in favor of the Borrower or any other Person.

Section 4. No Discharge or Diminishment of Guarantee . The obligations of the Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than the indefeasible payment in full in cash of the Guaranteed Obligations), including any claim of waiver, release, surrender, alteration, or compromise of any of the Guaranteed Obligations with respect to any other obligor, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of the Guarantor hereunder shall not be discharged or impaired or otherwise affected by the failure of the Administrative Agent or any Lender to assert any claim or demand or to enforce any remedy under the Credit Agreement, any other Loan Document or any other agreement, by any waiver or modification of any provision of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or omission that may or might in any manner or to any extent vary the risk of the Guarantor or that would otherwise operate as a discharge of the Guarantor as a matter of law or equity (other than the indefeasible payment in cash of the Obligations).

Section 5. Defenses of Borrower Waived . To the fullest extent permitted by applicable law, the Guarantor waives any defense based on or arising out of any defense of any Loan Party or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any Loan Party, other than the final and indefeasible payment in full in cash of the Guaranteed Obligations. The Administrative Agent and the Lenders may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept an assignment of any such security in lieu of foreclosure, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any other Loan Party or any other

Page 2

guarantor, without affecting or impairing in any way the liability of the Guarantor hereunder except to the extent the Guaranteed Obligations have been finally and indefeasibly paid in cash. Pursuant to applicable law, the Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of the Guarantor against the Borrower or any other guarantor, as the case may be, or any security.

Section 6. No Setoff or Deductions . The Guarantor shall make all payments hereunder without setoff or counterclaim. The Guarantor agrees to the provisions of Section 3.01 of the Credit Agreement that are applicable to the Guarantor, and such provisions are hereby incorporated by reference herein. The obligations of the Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Agreement.

Section 7. Information . The Guarantor assumes all responsibility for being and keeping itself informed of other Loan Parties’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that the Guarantor assumes and incurs hereunder, and agrees that none of the Administrative Agent or the Lenders will have any duty to advise the Guarantor of information known to it or any of them regarding such circumstances or risks.

Section 8. Indemnity and Subrogation .

TULSA, Okla. – June 30, 2017 – ONEOK, Inc. (NYSE: OKE) today announced that it has closed the acquisition of all outstanding common units of ONEOK Partners, L.P. (NYSE: OKS) it did not previously own, and the merger of ONEOK Partners with a subsidiary of ONEOK will be effective at the end of today. As a result of the acquisition, ONEOK Partners common units will no longer be publicly traded on the New York Stock Exchange.
