Ladies and Gentlemen:

ONEOK, Inc., an Oklahoma corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule II hereto (the “Underwriters”), for whom Barclays Capital Inc., X.X. Xxxxxx Securities LLC and Citigroup Global Markets Inc. are acting as representatives (the “Representatives”), 26,000,000 shares (the “Firm Securities”) of common stock, par value $0.01 per share (the “Common Stock”) of the Company. The Company also agrees to sell to the Underwriters, at the option of the Underwriters, an aggregate of not more than 3,900,000 additional shares (the “Optional Securities”) of Common Stock of the Company, as set forth below. The Firm Securities and the Optional Securities are herein collectively called the “Offered Securities.”

Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein, including, unless the context otherwise requires, the documents, if any, filed as exhibits to such incorporated documents; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the initial effective date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference.

This is to confirm the agreement (this “Agreement”) concerning the purchase of the Offered Securities from the Company by the Underwriters.

1. Representations and Warranties. The Company represents and warrants to, and agrees with, each Underwriter as set forth below in this Section 1.

(a) The Company meets the requirements for use of Form S-3 under the Act; the Company has prepared and filed with the Commission an “automatic shelf registration statement” (as defined in Rule 405) (File No. 333-219186), on Form S-3, including a related Base Prospectus, for registration under the Act of the offering and sale of the Offered Securities. Such Registration Statement, including any amendments thereto filed prior to the Applicable Time, became effective upon filing. The Company filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more Preliminary Prospectuses relating to the Offered Securities, each of which has previously been furnished to you. The Company will next file with the Commission one of the following: (1) a Final Prospectus in accordance with Rules 430B and 424(b) or (2) a Final Prospectus in accordance with Rules 415 and 424(b). The Company has included in such Registration Statement, as amended at the Effective Time, all information (other than information permitted to be excluded therefrom pursuant to Rule 430B (“Rule 430B Information”)) required by the Act to be included in such Registration Statement. As filed, the Final Prospectus shall contain all applicable Rule 430B Information, together with all other such information required by the Act and the rules thereunder, and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Applicable Time or, to the extent not completed at the Applicable Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the Applicable Time, will be included or made therein. The Registration Statement, at the Applicable Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Time of the Registration Statement was not earlier than the date three years before the Applicable Time.

(b) The Registration Statement complied when it became effective, complies as of the date hereof and, as amended or supplemented, at each Closing Date and at all times during which a prospectus is required by the Act to be delivered (whether physically or through compliance with Rule 172 under the Act or any similar rule) in connection with any sale of Offered Securities, will comply, in all material respects, with the requirements of the Act; and when the Final Prospectus is first filed in accordance with Rule 424(b) and on each Closing Date, the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder; as of the Effective Time and at the Applicable Time, the Registration Statement did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and on the date of any filing with the Commission pursuant to Rule 424(b) and on each Closing Date, the Final Prospectus (together with any supplement thereto) will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus (or any

supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement or the Final Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriters consists of the information described as such in Section 8(b) hereof.

(c) The Disclosure Package did not, as of the Applicable Time, contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package (or any amendments or supplement thereto), based upon and in conformity with information furnished in writing to the Company on behalf of any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(d) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Offered Securities in reliance on the exemption in Rule 163 and (iv) at the Applicable Time (with such date being used as the determination date for purposes of this clause (iv)), the Company was or is a Well-Known Seasoned Issuer. The Company agrees to pay the fees required by the Commission relating to the Offered Securities within the time required by Rule 456(b)(1) and otherwise in accordance with Rules 456(b) and 457(r).

(e) Prior to the execution of this Agreement, the Company has not, directly or indirectly, offered or sold any Offered Securities by means of any “prospectus” (within the meaning of the Act) or used any “prospectus” (within the meaning of the Act) in connection with the offer or sale of the Offered Securities, in each case other than the Preliminary Prospectuses and the Issuer Free Writing Prospectuses identified in Schedule III hereto.

(f) (i) At the earliest time after the filing of the Registration Statement that the Company made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Offered Securities and (ii) as of the Applicable Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not an “ineligible issuer” (as defined in Rule 405).

(g) Each Issuer Free Writing Prospectus does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein by reference and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(h) The only “significant subsidiaries” (as defined in Rule 1-02(w) of Regulation S-X) of the Company are the subsidiaries named on Annex A hereto (collectively, the “Subsidiaries”). The Company and each of its Subsidiaries is, and at each Closing Date will be, a corporation, limited liability company, general partnership or limited partnership, as the case may be, duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization. The Company and each of its Subsidiaries have, and at each Closing Date will have, full power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased, as the case may be, by it and to conduct its business in all material respects as described in the Disclosure Package and the Final Prospectus. The Company and each of its Subsidiaries is, and at each Closing Date will be, duly licensed or qualified to do business and in good standing as a foreign corporation, limited liability company, general partnership or limited partnership, as the case may be, in all jurisdictions in which the nature of the activities conducted by it or the character of the assets owned or leased, as the case may be, by it makes such licensing or qualification necessary, except to the extent that the failure to so qualify, be licensed or be in good standing would not reasonably be expected to have a material adverse effect on the condition (financial or otherwise), earnings, cash flow, business affairs or business prospects of the Company and its subsidiaries, considered as one enterprise (a “Material Adverse Effect”).

(i) All the outstanding equity interests of each Subsidiary have been duly and validly authorized and issued in accordance with such Subsidiary’s governing documents and are fully paid (in the case of any Subsidiary that is a limited liability company, to the extent required by such Subsidiary’s limited liability company agreement, and in the case of any Subsidiary that is a limited partnership, to the extent required by such Subsidiary’s agreement of limited partnership) and nonassessable (in the case of any Subsidiary that is a limited liability company, except as such nonassessability may be affected by Sections 18-607 and 18-804 of the Delaware Revised Limited Liability Company Act, and in the case of any Subsidiary that is a limited partnership, except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act and matters included in such Subsidiary’s agreement of limited partnership), and all outstanding equity interests of the Subsidiaries are owned by the Company either directly or through wholly-owned subsidiaries free and clear of any perfected security interest or any other security interests, claims, encumbrances or liens (“Liens”), except for any such Liens on the outstanding equity interests of the Subsidiaries that are described in the Disclosure Package and the Final Prospectus.

(j) As of the date of this Agreement, the Company has an authorized and outstanding capitalization as set forth in the sections of the Registration Statement, the Preliminary Prospectus and the Final Prospectus entitled “Capitalization” (and any similar sections or information, if any, contained in any Permitted Free Writing Prospectus (as defined herein)), and, as of each Closing Date, the Company shall have an authorized and outstanding capitalization as set forth in the sections of the Registration Statement, the Preliminary Prospectuses and the Final Prospectus entitled “Capitalization” (and any similar sections or information, if any, contained in any Permitted Free Writing Prospectus), except for such adjustments as are necessary to reflect the sale of the Offered Securities and the issuance and sale of Common Stock pursuant to the Company Equity Plans.

(k) There is no contract or other document of a character required to be described in the Registration Statement or Base Prospectus, or to be filed as an exhibit to the Registration Statement, which is not described or filed as required (and the Preliminary Prospectus contains in all material respects the same description of the foregoing matters as will be contained in the Base Prospectus, including the information incorporated by reference therein up to and through the date of this Agreement).

(l) This Agreement has been duly authorized, executed and delivered by or on behalf of the Company.

(m) The Offered Securities and all other outstanding shares of capital stock of the Company have been duly and validly authorized in accordance with the Company’s governing documents; all outstanding shares of capital stock of the Company are, and, when the Offered Securities have been issued and delivered against payment therefor in accordance with this Agreement on each Closing Date, such Offered Securities will be, duly and validly issued, fully paid and non-assessable, and free of statutory and contractual preemptive rights, resale rights, rights of first refusal and similar rights; the Offered Securities, when issued and delivered against payment therefor in accordance with this Agreement on each Closing Date, will be free of any restriction upon the voting or transfer thereof pursuant to any agreement or other instrument to which the Company is a party; and the statements under the caption “Description of Capital Stock” in the Base Prospectus and contained or incorporated by reference in the Registration Statement, insofar as such statements summarize certain provision of documents referred to therein, fairly summarize such provisions in all material respects.

(n) The Company is not and, after giving effect to the offering and sale of the Offered Securities and the application of the proceeds thereof as described in the Disclosure Package and the Final Prospectus, will not be an “investment company” as defined in the Investment Company Act of 1940, as amended.

(o) No consent, approval, authorization, filing with or order of any court or governmental agency or body is required in connection with the transactions contemplated herein except (i) such as have been obtained under the Act and (ii) such as may be required under the blue sky laws of any jurisdiction or the by-laws and rules of the Financial Industry Regulatory Authority (“FINRA”) in connection with the purchase and distribution by the Underwriters of the Offered Securities in the manner contemplated herein and in the Disclosure Package and the Final Prospectus or (iii) such that the failure to obtain would not reasonably be expected to result in a Material Adverse Effect.

(p) Neither the issuance and sale of the Offered Securities nor the consummation of any other of the transactions herein contemplated nor the fulfillment of the terms hereof will conflict with, result in a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its Subsidiaries pursuant to (i) the provisions of the certificate of incorporation or by-laws or other governing documents of the Company or any of the governing documents of any of its Subsidiaries, (ii) the

terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which the Company or any of its Subsidiaries is a party or bound or to which its or their property is subject, or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company or any of its Subsidiaries of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of its Subsidiaries or any of its or their properties, which conflicts, breaches, violations or defaults, in the case of clauses (ii) or (iii), would reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

(q) Except for the Underwriters (who shall act as underwriters with respect to the Offered Securities pursuant to this Agreement), no person has the right to act as an underwriter or as a financial advisor to the Company in connection with the offer and sale of the Offered Securities.

(r) No holders of securities of the Company have rights to the registration of such securities under the Disclosure Package, the Final Prospectus and the Registration Statement.

(s) The historical consolidated financial statements and schedules of the Company and its consolidated subsidiaries included or incorporated by reference in the Disclosure Package, the Final Prospectus and the Registration Statement present fairly in all material respects the consolidated financial condition, results of operations and cash flows of the Company as of the dates and for the periods indicated, comply as to form in all material respects with the applicable accounting requirements of the Act and have been prepared in conformity with generally accepted accounting principles applied on a consistent basis throughout the periods involved (except as otherwise noted therein). The interactive data in eXtensible Business Reporting Language (“XBRL”) included or incorporated by reference in the Registration Statement, the Final Prospectus and the Disclosure Package fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(t) Other than as set forth in the Disclosure Package, the Final Prospectus and the Registration Statement, no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its Subsidiaries or its or their property is pending or, to the Company’s knowledge, threatened that (i) would reasonably be expected to have a material adverse effect on the performance of this Agreement or the consummation of any of the transactions contemplated hereby or (ii) would reasonably be expected to have a Material Adverse Effect.

(u) Each of the Company and each of its Subsidiaries owns or leases all such properties as are necessary to the conduct of its operations as presently conducted except where the failure to do so does not materially interfere with the ownership, operation or benefits of operation of such businesses or materially increase the cost of operation or ownership of such businesses; provided that (a) with respect to the transmission and gathering pipelines of the Company and the Subsidiaries that own such pipelines and right-of-way interests related thereto (the “Pipeline Properties”), the foregoing shall only constitute a representation that such

Subsidiaries have sufficient title to enable them to use such Pipeline Properties in their businesses as they have been used in the past and as are proposed to be used in the future and will not materially increase the cost of such use, and (b) with respect to any real property, buildings and equipment held under lease by the Subsidiaries, such real property, buildings and equipment are held by the Subsidiaries under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such real property, buildings and equipment for such Subsidiary.

(v) Neither the Company nor any Subsidiary is in violation or default of (i) any provisions of the certificate of incorporation or by-laws or other governing documents of the Company or the governing documents of such Subsidiary, as the case may be, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which it is a party or bound or to which its property is subject or (iii) any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or such Subsidiary or any of its properties, as applicable, except in the case of clauses (ii) and (iii) as would not reasonably be expected to have a Material Adverse Effect or as could not materially impair the ability of the Company to perform its obligations under this Agreement.

(w) PricewaterhouseCoopers LLP, who has audited certain financial statements of the Company and its consolidated subsidiaries included, or incorporated by reference, in the Disclosure Package and the Final Prospectus, is an independent registered public accounting firm with respect to the Company as required by the Act and the Public Company Accounting Oversight Board (United States) and its applicable published rules and regulations.

(z) No labor problem or dispute with the employees of the Company or any of its Subsidiaries exists or, to the Company’s knowledge, is threatened or imminent, that would reasonably be expected to have a Material Adverse Effect.

(aa) The Company and the Subsidiaries are insured by insurers that the Company has no reason to believe are not of recognized financial responsibility against such losses and risks and in such amounts as the Company believes are prudent and customary in the businesses in which they are engaged.

(bb) The Company and its Subsidiaries possess all licenses, certificates, permits and other authorizations issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses, except for such licenses, certificates, permits and other authorizations that, if not obtained, would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any such Subsidiary has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus.

(cc) The Company and each of its subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of the Company’s financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (v) the interactive data in XBRL included or incorporated by reference in the Registration Statement, the Final Prospectus and the Disclosure Package has been prepared in accordance with the Commission’s applicable rules and guidelines.

On the basis of such reviews, the Company has reasonably concluded that such associated liabilities would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Any certificate signed by or on behalf of the Company and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Offered Securities and pursuant to the terms of this Agreement shall be deemed a representation and warranty by the Company, as the case may be, as to matters covered thereby, to each Underwriter.

2. Purchase and Sale.

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at the purchase price set forth in Schedule I hereto the number of the Firm Securities set forth opposite such Underwriter’s name in Schedule II hereto.

(b) In addition, upon written notice from the Representatives given to the Company from time to time not more than 30 days subsequent to the date of the Final

Prospectus, the Underwriters shall have the option to purchase all or less than all of the Optional Securities at the purchase price per share to be paid for the Firm Securities set forth in Schedule I; provided that if the 30th day subsequent to the date of the Final Prospectus falls on a day that is not a Business Day, the option granted in this Section 2(b) will expire on the next succeeding Business Day. The Company agrees to sell to the Underwriters the number of shares of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representatives to the Company.

3. Delivery and Payment. Delivery of and payment for the Firm Securities shall be made on June 16, 2020 at 9:00 a.m. New York City time or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the Company or as provided in Section 9 hereof (such date and time of delivery and payment for the Firm Securities being herein called the “First Closing Date”). Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date,” which may be on or after the First Closing Date (the First Closing Date and each Optional Closing Date, if any, are referred to herein as the “Closing Date”), shall be determined by the Representatives but shall not occur later than five full business days after written notice of election to purchase Optional Securities is given.

Delivery of the Offered Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. Delivery of the Offered Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.

4. Offering by Underwriters. The several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

5. Agreements. The Company agrees with the several Underwriters that:

(a) Prior to the termination of the offering of the Offered Securities, the Company will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object, unless, (i) in the judgment of counsel to the Company, such filing is required by applicable law or (ii) is advisable in furtherance of a

Commission request. Subject to the foregoing sentence, if the Registration Statement has become or becomes effective pursuant to Rule 430B, or filing of the Final Prospectus is otherwise required under Rule 424(b), the Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. The Company will promptly advise the Representatives (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of the offering of Offered Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its reasonable best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, will promptly use its reasonable best efforts to obtain the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made, not misleading, the Company will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(c) If, at any time when a prospectus relating to the Offered Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made at such time, not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company promptly will (i) notify the Representatives of any such event, (ii) prepare and file with the Commission, subject to the second sentence of Section 5(a), an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its reasonable best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(d) As soon as practicable, the Company will make generally available, via the Commission’s Electronic Data Gathering, Analysis and Retrieval (XXXXX) System, to its security holders and to the Representatives an earnings statement or statements of the Company and its subsidiaries (which need not be audited) which will satisfy the provisions of Section 11(a) of the Act, including, at the option of the Company, Rule 158, which may be satisfied through the filing with the Commission of reports required under the Exchange Act.

(e) The Company will furnish or otherwise make available upon request to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering (other than internal sales memoranda prepared by any of the Underwriters).

(f) The Company will arrange, if necessary, for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives may reasonably designate, will maintain such qualifications in effect so long as reasonably required for the distribution of Offered Securities and will pay any fee of FINRA in connection with its review of the offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Offered Securities, in any jurisdiction where it is not now so subject.

(g) The Company agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto. Any such Free Writing Prospectus consented to by the Representatives or the Company is herein referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as applicable and as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(h) Beginning on the date hereof and ending on, and including, the date that is 60 days after the date of the Prospectus Supplement (the “Company Lock-Up Period”), the Company will not, without the prior written consent of Barclays Capital Inc., offer, sell, contract to sell, pledge or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company) directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other shares of Common Stock or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock; or publicly announce an intention to effect any such transaction. Notwithstanding the foregoing, the Company may (A) issue and sell the Offered Securities pursuant to this Agreement, (B) file a registration statement on Form S-8 or issue and sell shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock, in each case, only pursuant the Company Equity Plans, (C) issue or deliver shares of Common Stock issuable upon the conversion, vesting or exercise of securities (including long-term incentive plan awards, options and warrants) outstanding at the Applicable Time, (D) file a “universal” shelf registration statement with respect to the Company’s debt or Common Stock for the purpose of increasing the capacity under or replacing the Company’s then existing “universal” shelf registration statement; provided that no securities will be offered or sold pursuant to any such registration statement except as otherwise specifically permitted pursuant to this Section 5(h), (E) issue and sell Common Stock pursuant to the Company’s Direct Stock Purchase and Dividend Reinvestment Plan and/or file a shelf registration statement with respect to the Company’s Direct Stock Purchase and Dividend Reinvestment Plan for the purposes of increasing the capacity under or replacing the Company’s then-existing shelf registration statement covering the Direct Stock Purchase and Dividend Reinvestment Plan and (F) enter into an equity distribution agreement for an “at the market offering” under Rule 415(a)(4) of the Act for the purposes of the sale of Common Stock, make any related filings under the Act or the Exchange Act, including a prospectus supplement and Current Report on Form 8-K; provided that no Common Stock is sold thereunder during the Company Lock-Up Period.

(i) The Company will not, at any time at or after the execution of this Agreement, directly or indirectly, offer or sell any Offered Securities by means of any “prospectus” (within the meaning of the Act), or use any “prospectus” (within the meaning of the Act) in connection with the offer or sale of the Offered Securities, in each case other than the Final Prospectus.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Offered Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Applicable Time and each Closing Date, to the accuracy of the statements of the Company made in any

certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a) The Final Prospectus, and any supplement thereto, shall have been filed in the manner and within the time period required by Rule 424(b); any material required to be filed by the Company pursuant to Rule 433(d) under the Act shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433; and no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

(d) The Representatives shall have received from Shearman & Sterling LLP, counsel for the Underwriters, such opinion or opinions, dated each Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Offered Securities, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(e) The Company shall have furnished to the Representatives a certificate of the Company, signed by its Chief Executive Officer, President or a Vice President and the Chief Financial Officer, dated each Closing Date, to the effect that the signers of such certificate have reviewed the Registration Statement, the Final Prospectus, the Disclosure Package and any supplements or amendments thereto and this Agreement and that:

(i) the representations and warranties of the Company in Section 1 of this Agreement are true and correct on and as of each Closing Date with the same effect as if made on each Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to each Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued by the Commission and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iii) since the date of the most recent financial statements included in the Disclosure Package and the Final Prospectus, there has been no Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus.

(f) The Company shall have requested and caused PricewaterhouseCoopers LLP to have furnished to the Representatives, at the Applicable Time and at each Closing Date, “comfort letters” (which may refer to letters previously delivered to the Representatives), dated respectively as of the Applicable Time and as of each Closing Date, in form and substance satisfactory to the Representatives and PricewaterhouseCoopers LLP, with respect to the certain unaudited financial statements and financial information contained in the Registration Statement, the Preliminary Prospectus used most recently prior to the Applicable Time and the Final Prospectus.

(g) Subsequent to the Applicable Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any amendment thereto), there shall not have been (i) any adverse change or decrease specified in the letters referred to in paragraph (f) of this Section 6 or (ii) any adverse change, or any development involving a prospective adverse change, in or affecting the business, properties, earnings, results of operations or financial condition of the Company and its subsidiaries, taken as a whole, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of any series of Offered Securities as contemplated by the Registration Statement, the Disclosure Package and the Final Prospectus.

(h) Subsequent to the Applicable Time, there shall not have been any decrease in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

Notice of such cancellation shall be given to the Company in writing or by telephone, email or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Shearman & Sterling LLP, counsel for the Underwriters, at 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, on each Closing Date, or as otherwise agreed by the Company and the Representatives.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay, or reimburse if paid by the Underwriters, all costs and expenses incident to the performance of the obligations of the Company under this Agreement, including but not limited to costs and expenses of or relating to (i) the preparation, printing and filing of the Registration Statement and exhibits to it, the Preliminary Prospectus and the Final Prospectus, and any amendment or supplement to the Registration Statement or the Preliminary Prospectus and Final Prospectus, (ii) the preparation and delivery of certificates representing the Offered Securities, (iii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Offered Securities, (iv) furnishing (including costs of shipping, mailing and courier) such copies of the Registration Statement, the Preliminary Prospectus or Final Prospectus, and all amendments and supplements thereto, as may be requested for use in connection with the offering and sale of the Offered Securities by the Underwriters or by dealers to whom Offered Securities may be sold, (v) any filings required to be made by the Underwriters with FINRA, and the reasonable fees, disbursements and other charges of counsel to the Underwriters in connection therewith, (vi) the registration or qualification of the Offered Securities for offer and sale under the securities or Blue Sky laws, including the reasonable fees, disbursements and other charges of counsel to the Underwriters in connection therewith, and the preparation and printing of preliminary, supplemental and final Blue Sky memoranda, (vii) counsel to the Company and (viii) PricewaterhouseCoopers LLP. Except as provided in this Section 7, the Underwriters will pay all of their own fees and expenses in connection with the offering and sale of the Offered Securities.

(b) If the sale of the Offered Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10(i) hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Offered Securities.

8. Indemnification and Contribution. (a) The Company agrees, jointly and severally, to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or

liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Offered Securities, the Final Prospectus or any Issuer Free Writing Prospectus, any information that the Company has filed or is required to file pursuant to Rule 433(d) under the Act, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriters consists of the information described as such in Section 8(b). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors and officers and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that (i) the statements set forth in the last paragraph of the cover page regarding delivery of the Offered Securities, and (ii) the following information under the heading “Underwriting”: (A) the first sentence of the fifth paragraph related to selling concessions, (B) the information in the first and second paragraphs under the heading “Stabilization” and (C) the information in the first sentence of the first paragraph and the second paragraph under the heading “Underwriters’ Conflicts of Interest” in the Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the

indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and only to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle, compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, but is otherwise applicable in accordance with its terms, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Offered Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Offered Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Offered Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other, in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the

Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether an untrue or an alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, on the one hand, or the Underwriters, on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Offered Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Firm Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Firm Securities set forth opposite the names of all the remaining Underwriters) the Offered Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Offered Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Offered Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Offered Securities, and if such nondefaulting Underwriters do not purchase all the Offered Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). In the event of a default by any Underwriter as set forth in this Section 9, a Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 9. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Offered Securities, if at any time prior to such time (i) trading in any securities of the Company shall have been suspended by the Commission or the New York Stock Exchange or (ii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering, sale or delivery of the Offered Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Offered Securities. The provisions of Sections 7 and 8 and the last sentence of Section 9 hereof shall survive the termination or cancellation of this Agreement.

12. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(c) For purposes of this Section 12, a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution

Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

Ladies and Gentlemen:

This Lock-Up Agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) to be entered into by ONEOK, Inc., an Oklahoma corporation (the “Company”), and Barclays Capital Inc. (“Barclays”), X.X. Xxxxxx Securities LLC and Citigroup Global Markets Inc., as representatives, and the other underwriters listed in Schedule II to the Underwriting Agreement, with respect to the public offering (the “Offering”) of shares of common stock, par value $0.01 (the “Stock”) of the Company (the “Shares”).

In order to induce you to enter into the Underwriting Agreement, the undersigned agrees that, for a period (the “Lock-Up Period”) beginning on the date hereof and ending on, and including, the date that is 60 days after the date of the final prospectus supplement relating to the Offering, the undersigned will not, without the prior written consent of Barclays, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission (the “Commission”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (the “Exchange Act”) with respect to, any Shares or any other securities of the Company that are substantially similar to the Shares, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Shares or any other securities of the Company that are substantially similar to Shares, or any

securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, whether any such transaction is to be settled by delivery of Shares or such other securities, in cash or otherwise or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii).

Barclays agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Stock by an officer or director of the Company, Barclays will notify the Company of the impending release or waiver. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

Notwithstanding the foregoing, this Lock-Up Agreement shall not apply to (a) the registration of the offer and sale of Shares as contemplated by the Underwriting Agreement and the sale of the Shares to the Underwriters (as defined in the Underwriting Agreement) in the Offering, (b) bona fide gifts, (c) dispositions to any trust, partnership, limited liability company or other entity for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, (d) dispositions by will or intestacy, (e) dispositions to any immediate family member or other dependent, (f) a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (b) through (e) above, (g) dispositions pursuant to an order of a court or regulatory agency, (h) dispositions from an executive officer to the Company or its parent entities upon death, disability or termination of employment, in each case, of such executive officer, (i) transfers to the Company (1) pursuant to the exercise, in each case on a “cashless” or “net exercise” basis, of any option to purchase shares of Stock granted by the Company pursuant to any employee benefit plans or arrangements described in the Pricing Disclosure Package, where any shares of Stock received by the undersigned upon any such exercise will be subject to the terms of this Lock-Up Agreement or (2) for the purpose of satisfying any withholding taxes (including estimated taxes) due as a result of the exercise of any option to purchase shares of Stock or the vesting of any restricted stock awards granted by the Company pursuant to employee benefit plans or arrangements described in the Pricing Disclosure Package, in each case on a “cashless” or “net exercise” basis, where any shares of Stock received by the undersigned upon any such exercise or vesting will be subject to the terms of this Lock-Up Agreement, and/or (j) transfers with the prior written consent of Barclays; provided, however, that (x) in the case of each transfer or distribution pursuant to clauses (b), (c), (e), (f) and (h) above, (i) each donee, trustee, distribute or transferee, as the case may be, agrees to be bound in writing by the restrictions set forth herein and (ii) any such transfer or distribution shall not involve a disposition for value and (y) in the case of each transfer or distribution pursuant to clauses (b), (c), (d), (e), (f), (h) or (i) above, if any public reports or filings (including filings under Section 16(a) of the Exchange Act) reporting a reduction in beneficial ownership of Stock shall be required or shall be voluntarily made during the Lock-Up Period (a) the undersigned shall provide Barclays prior written notice informing it of such report or filing and (b) such report or filing shall disclose that such donee, trustee, distributee or transferee, as the case may be, agrees to be bound in writing by the restrictions set forth herein. For purposes of this paragraph, “immediate family” shall mean the undersigned and the spouse, any lineal descendent, father, mother, brother or sister of the undersigned.

C-2

The undersigned hereby confirms that the undersigned has not, directly or indirectly, taken, and hereby covenants that the undersigned will not, directly or indirectly, take, any action designed, or which has constituted or will constitute or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of Shares.

If (i) the Company notifies you in writing that it does not intend to proceed with the Offering, (ii) the registration statement filed with the Commission with respect to the Offering is withdrawn, (iii) for any reason the Underwriting Agreement shall be terminated prior to the “time of purchase” (as defined in the Underwriting Agreement) or (iv) the Underwriting Agreement is not executed by July 11, 2020, this Lock-Up Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.
