at its own cost and expense and shall notify Parent of its determination, which determination shall not be binding upon Parent. Parent shall provide reasonably timely updates of the allocation of Tax Attributes as it finalizes its Tax Returns and as

Spinco to) cooperate with Parent and take any and all actions reasonably requested by Parent in connection with obtaining the Ruling or Unqualified Tax Opinion (including, without limitation, by making any representation or covenant or providing any
materials or information requested by the IRS or Tax Advisor; provided that Spinco shall not be required to make (or cause any Affiliate of Spinco to make) any representation or covenant that is inconsistent with historical facts or as to
future matters or events over which it has no control). Parent shall reimburse Spinco for all reasonable costs and expenses, including expenses relating to the utilization of Spinco personnel, incurred by the Spinco Group in connection with such
cooperation within ten Business Days after receiving an invoice from Spinco therefor. 
 (d) Spinco hereby agrees that Parent shall have
sole and exclusive control over the process of obtaining any Ruling, and that only Parent shall apply for a Ruling. In connection with obtaining a Ruling pursuant to Section 6.03(b), (A) Parent shall keep Spinco informed in a timely
manner of all material actions taken or proposed to be taken by Parent in connection therewith; (B) Parent shall (1) reasonably in advance of the submission of any Ruling Request documents provide Spinco with a draft copy thereof,

limitation, stock issuances, pursuant to the exercise of stock options or otherwise, option grants, capital contributions or acquisitions, or a series of such transactions or events) that cause the Distribution to be treated as part of a plan
pursuant to which one or more Persons acquire directly or indirectly Spinco Capital Stock representing a Fifty-Percent or Greater Interest therein, (C) any action or failure to act by Spinco after the Distribution (including, without
limitation, any amendment to Spinco’s certificate of incorporation (or other organizational documents), whether through a stockholder vote or otherwise) affecting the voting rights of Spinco Capital Stock (including, without limitation, through
the conversion of one class of Spinco Capital Stock into another class of Spinco Capital Stock), (D) any act or failure to act by Spinco or any Spinco Affiliate described in Section 6.01 (regardless of whether such act or failure to
act may be covered by a Ruling, Unqualified Tax Opinion or waiver described in clause (A), (B) or (C) of Section 6.01(c), a Board Certificate described in Section 6.01(d), or a consent described in
Section 6.01(e)) or (E) any breach by Spinco of its agreement and representation set forth in Section 6.01(a) – 6.01(e). 

(b) Notwithstanding anything in this Agreement or the Separation Agreement to the contrary, Parent shall be responsible for, and shall
indemnify and hold harmless the Spinco Indemnitees from and against, one hundred percent (100%) of any Tax-Related Losses that are attributable to, or result from any one or more of the following: (A) the acquisition (other than pursuant
to the Separation or the Distribution) of all or a portion of Parent’s stock and/or its assets by any means whatsoever by any Person, (B) any negotiations, agreements or arrangements by Parent with respect to transactions or events
(including, without limitation, stock issuances, pursuant to the exercise of stock options or otherwise, option grants, capital contributions or acquisitions, or a series of such transactions or events) that cause the Distribution to be treated as
part of a plan pursuant to which one or more Persons acquire directly or indirectly stock of Parent representing a Fifty-Percent or Greater Interest therein, (C) any act or failure to act by Parent or a member of the Parent Group described in
Section 6.02 or any breach by Parent of its agreement and representation set forth in Section 6.02. 
 (c) For
purposes of calculating the amount and timing of any Tax-Related Loss for which Spinco is responsible under this Section 6.04, Tax-Related Losses shall be calculated by assuming that Parent, the Parent Affiliated Group and each member of
the Parent Group (I) pay Tax at the highest marginal corporate Tax rates in effect in each relevant taxable year and (II) have no Tax Attributes in any relevant taxable year. 

(d) Spinco shall pay Parent the amount of any Tax-Related Losses for which Spinco is responsible under this Section 6.04:
(A) in the case of Tax-Related Losses described in clause (i) of the definition of Tax-Related Losses no later than two Business Days prior to the 

  
 19 

 
date Parent pays such Tax-Related Losses, and (B) in the case of Tax-Related Losses described in clause (ii) or (iii) of the definition of Tax-Related Losses, no later than two
Business Days after the date Parent pays such Tax-Related Losses. Parent shall pay Spinco the amount of any Tax-Related Losses for which Parent is responsible under this Section 6.04: (A) in the case of Tax-Related Losses described
in clause (i) of the definition of Tax-Related Losses no later than two Business Days prior to the date Spinco pays such Tax-Related Losses, and (B) in the case of Tax-Related Losses described in clause (ii) or (iii) of the
definition of Tax-Related Losses, no later than two Business Days after the date Spinco pays such Tax-Related Losses. 
 Section 7.
Assistance and Cooperation. 
 Section 7.01 Assistance and Cooperation. 

(a) The Parties shall cooperate (and cause their respective Affiliates to cooperate) with each other and with each other’s agents,
including accounting firms and legal counsel, in connection with Tax matters relating to the Parties and their Affiliates including (i) preparation and filing of Tax Returns, (ii) determining the liability for and amount of any Taxes due
(including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in respect of Taxes assessed or proposed to be assessed. Such cooperation
shall include making all information and documents in their possession relating to the other Party and its Affiliates available to such other Party as provided in Section 8. Each of the Parties shall also make available to the other, as
reasonably requested and available, personnel (including officers, directors, employees and agents of the Parties or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes,
and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. Spinco shall cooperate with Parent and take any and all actions
reasonably requested by Parent in connection with obtaining the Tax Opinions/Rulings (including, without limitation, by making any new representation or covenant, confirming any previously made representation or covenant or providing any materials
or information requested by any Tax Advisor or Tax Authority; provided that Spinco shall not be required to make or confirm any representation or covenant that is inconsistent with historical facts or as to future matters or events over which
it has no control). 
 (b) Any information or documents provided under this Section 7 or Section 8 shall be kept
confidential by the Party receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes. Notwithstanding
any other provision of this Agreement or any other agreement, (i) neither Parent nor any Parent Affiliate shall be required to provide Spinco or any Spinco Affiliate or any other Person access to or copies of any information, documents or
procedures (including the proceedings of any Tax Contest) other than information, documents or procedures that relate to Spinco, the business or assets of Spinco or any Spinco Affiliate and (ii) in no event shall Parent or any Parent Affiliate
be required to provide Spinco, any Spinco Affiliate or any other Person access to or copies of any information or documents if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event that Parent
determines that the provision of any information or 

  
 20 

 
documents to Spinco or any Spinco Affiliate could be commercially detrimental, violate any law or agreement or waive any Privilege, the Parties shall use reasonable best efforts to permit
compliance with its obligations under this Section 7 in a manner that avoids any such harm or consequence. 

Section 7.02 Tax Return Information. Spinco and Parent acknowledge that time is of the essence in relation to any request
for information, assistance or cooperation made by Parent or Spinco pursuant to Section 7.01 or this Section 7.02. Spinco and Parent acknowledge that failure to conform to the reasonable deadlines set by Parent or Spinco
could cause irreparable harm. Each Party shall provide to the other Party information and documents relating to its Group required by the other Party to prepare Tax Returns, including, but not limited to, any Pro Forma Spinco Group Consolidated
Return prepared by Parent for purposes of preparing Joint Returns. Any information or documents the Responsible Party requires to prepare such Tax Returns shall be provided in such form as the Responsible Party reasonably requests and at or prior to
the time reasonably specified by the Responsible Party so as to enable the Responsible Party to file such Tax Returns on a timely basis. 

Section 7.03 Reliance by Parent. If any member of the Spinco Group supplies information to a member of the Parent Group in
connection with a Tax liability and an officer of a member of the Parent Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the
Parent Group identifying the information being so relied upon, the chief financial officer of Spinco (or any officer of Spinco as designated by the chief financial officer of Spinco) shall certify in writing that to his or her knowledge (based upon
consultation with appropriate employees) the information so supplied is accurate and complete. 
 Section 7.04 Reliance by
Spinco. If any member of the Parent Group supplies information to a member of the Spinco Group in connection with a Tax liability and an officer of a member of the Spinco Group signs a statement or other document under penalties of perjury in
reliance upon the accuracy of such information, then upon the written request of such member of the Spinco Group identifying the information being so relied upon, the chief financial officer of Parent (or any officer of Parent as designated by the
chief financial officer of Parent) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. 

Section 8. Tax Records. 

Section 8.01 Tax Records. Each Party shall preserve and keep, and shall cause their respective Affiliates to preserve and
keep, all Tax Records that are in their possession, and that could affect the liability of any member of the other Group for Taxes, for so long as the contents thereof may become material in the administration of any matter under the Code or other
applicable Tax Law, but, in any event, until the later of (i) the expiration of any applicable statutes of limitations, or (ii) seven years after the Distribution Date (such later date, the “Retention Date”). After the
Retention Date, each Party may, and may allow its respective Affiliates to, dispose of such Tax Records upon 60 Business Days’ prior written notice to the other Party. If, prior to the Retention Date, (a) a Party reasonably
determines that any Tax Records which it, or any of its Affiliates, would otherwise be required to preserve and keep 

  
 21 

 
under this Section 8.01 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Party agrees, then such first Party, or the
applicable Affiliate, may dispose of such Tax Records upon 60 Business Days’ prior notice to the other Party. Any notice of an intent to dispose given pursuant to this Section 8.01 shall include a list of the Tax Records to
be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Party shall have the opportunity, at its cost and expense, to copy or remove, within such 60 Business Day period, all or any
part of such Tax Records. If, at any time prior to the Retention Date, Spinco determines to decommission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then Spinco may
decommission or discontinue such program or system upon 90 days’ prior notice to Parent and Parent shall have the opportunity, at its cost and expense, to copy, within such 60 Business Day period, all or any part of the underlying data
relating to the Tax Records accessed by or stored on such program or system. 
 Section 8.02 Access to Tax Records. The Parties
and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records (and, for the avoidance of doubt, any pertinent underlying data accessed or stored on
any computer program or information technology system) in their possession and shall permit the other Party and its Affiliates, authorized agents and representatives and any representative of a Tax Authority or other Tax auditor direct access, at
the cost and expense of such other Party, during normal business hours upon reasonable notice to any computer program or information technology system used to access or store any Tax Records, in each case to the extent reasonably required by the
other Party in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement. 

Section 8.03 Preservation of Privilege. No member of the Spinco Group shall provide access to, copies of, or otherwise disclose to
any Person any documentation relating to Taxes existing prior to the Distribution Date to which Privilege may reasonably be asserted without the prior written consent of Parent, such consent not to be unreasonably withheld. 

Section 9. Tax Contests. 

Section 9.01 Notice. Each of the Parties shall provide prompt notice to the other Party of any written communication from a Tax
Authority regarding any pending Tax Contest of which it becomes aware related to Taxes for Tax Periods for which it may be indemnified by the other Party hereunder or for which it may be required to indemnify the other Party hereunder. Such notice
shall attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any
notice and other documents received from any Tax Authority in respect of any such matters. If an indemnified Party has knowledge of an asserted Tax liability with respect to a matter for which it is to be indemnified hereunder and such Party fails
to give the indemnifying Party prompt notice of such asserted Tax liability and the indemnifying Party is entitled under this Agreement to contest the asserted Tax liability, then (i) if the indemnifying Party is precluded from contesting the
asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying Party shall have no obligation to indemnify the indemnified Party for any Taxes arising out of such

  
 22 

 
asserted Tax liability, and (ii) if the indemnifying Party is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a
material monetary detriment to the indemnifying Party, then any amount which the indemnifying Party is otherwise required to pay the indemnified Party pursuant to this Agreement shall be reduced by the amount of such detriment. 

Section 9.02 Control of Tax Contests. 

(a) Separate Returns. In the case of any Tax Contest with respect to any Separate Return, the Party having liability for the Tax
pursuant to Section 3 hereof shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 9.02(c) and (d) below. 

(b) Joint Returns. In the case of any Tax Contest with respect to any Joint Return, Parent shall have exclusive control over the Tax
Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 9.02(c) and (d) below. 

(c) Settlement Rights. The Controlling Party shall have the sole right to contest, litigate, compromise and settle any Tax Contest
without obtaining the prior consent of the Non-Controlling Party. Unless waived by the Parties in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be
expected to become liable to make any indemnification payment to the Controlling Party under this Agreement: (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken
by the Controlling Party with respect to such potential adjustment in such Tax Contest; (ii) the Controlling Party shall timely provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax
Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such
potential adjustment in such Tax Contest; (iv) the Controlling Party shall consult with the Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or
furnished in connection with such potential adjustment in such Tax Contest; and (v) the Controlling Party shall defend such Tax Contest diligently and in good faith. The failure of the Controlling Party to take any action specified in the
preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling
Party was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party. In the case of any Tax Contest described in
Section 9.02(a) or (b), “Controlling Party” means the Party entitled to control the Tax Contest under such Section and “Non-Controlling Party” means the other Party. 

(d) Tax Contest Participation. Unless waived by the Parties in writing, the Controlling Party shall provide the Non-Controlling Party
with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any
potential adjustment in a Tax Contest pursuant to which the 

  
 23 

 
Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement. The failure of the Controlling Party to
provide any notice specified in this Section 9.02(d) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling
Party under this Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the
Controlling Party. 
 (e) Power of Attorney. Each member of the Spinco Group shall execute and deliver to Parent (or such member of
the Parent Group as Parent shall designate) any power of attorney or other similar document reasonably requested by Parent (or such designee) in connection with any Tax Contest (as to which Parent is the Controlling Party) described in this
Section 9. Each member of the Parent Group shall execute and deliver to Spinco (or such member of the Spinco Group as Spinco shall designate) any power of attorney or other similar document requested by Spinco (or such designee) in
connection with any Tax Contest (as to which Spinco is the Controlling Party) described in this Section 9. 

Section 10. Effective Date. This Agreement shall be effective as of the date hereof (the “Effective Date”). 

Section 11. Survival of Obligations. The representations, warranties, covenants and agreements set forth in this Agreement
shall be unconditional and absolute and shall remain in effect without limitation as to time. 
 Section 12. Treatment of
Payments. In the absence of any change in Tax treatment under the Code or except as otherwise required by other applicable Tax Law, any Tax indemnity payments made by a Party under this Agreement shall be reported for Tax purposes by the Payor
and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Distribution (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of
the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability. Any Tax indemnity payment made by a Party
under this Agreement shall be increased as necessary so that after making all payments in respect of Taxes imposed on or attributable to such indemnity payment, the recipient Party receives an amount equal to the sum it would have received had no
such Taxes been imposed; provided that a payment of interest shall be treated as reasonably determined by Parent. 

Section 13. Disagreements. 

Section 13.01 Discussion. The Parties will use commercially reasonable efforts, and they will cause their respective Group
members to use commercially reasonable efforts, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto. In furtherance
thereof, in the event of any dispute or disagreement (a “Dispute”) between any member of the Parent Group and any member of the Spinco Group as to the interpretation of any provision of this Agreement or the performance of
obligations hereunder, the Tax departments of the Parties shall negotiate in good faith to resolve the Dispute. If such good faith negotiations do 

  
 24 

 
not resolve the Dispute, then the matter, upon written request of either Party, will be referred to the Persons at each Party holding the title of General Counsel (or such other chief legal
officer at such Party) for resolution. If such Dispute is not resolved within ninety (90) Business Days following the date on which the General Counsel (or such other chief legal officer at such Party) receive notification, the Parties to such
Dispute shall each separately retain an independent, nationally recognized law or accounting firm (each, a “Preliminary Tax Advisor” and, together, the “Preliminary Tax Advisors”), which Preliminary Tax Advisors
shall jointly select a Tax Advisor on behalf of the Parties to the Dispute to act as an arbitrator in order to resolve the Dispute. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser, accounting firm or
consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to the Parties of its resolution of any such Dispute as soon as practical, but in any event no later than 60
Business Days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be conclusive and binding on the Parties. Following receipt of the Tax Advisor’s written notice to the Parties of its resolution of the
Dispute, the Parties shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. All fees and expenses of the Preliminary Tax Advisor shall be borne by the Party that engaged such advisor and all of the
fees and expenses of the Tax Advisor shall be shared equally by each of the Parties to the Dispute. 
 Section 13.02 Injunctive
Relief. Nothing in this Section 13 will prevent either Party from seeking injunctive relief if any delay resulting from the efforts to resolve the Dispute through the process set forth above could result in serious and
irreparable injury to either Party. Notwithstanding anything to the contrary in this Agreement, Parent and Spinco are the only members of their respective Groups entitled to commence a dispute resolution procedure under this Agreement, and each of
Parent and Spinco will cause its respective Group members not to commence any dispute resolution procedure other than through such Party as provided in this Section 13. 

Section 14. Late Payments. Any amount owed by one Party to another Party under this Agreement which is not paid when due shall
bear interest at the Prime Rate plus 2% per annum from the due date of the payment to the date paid. 
 Section 15.
Expenses. Except as otherwise provided in this Agreement, each Party and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions
of this Agreement.

Section 16.02 Waivers and Consents. The failure of any Party to require strict performance by the other Party of any
provision in this Agreement will not waive or diminish that Party’s right to demand strict performance thereafter of that or any other provision hereof. Any consent required or permitted to be given by any Party to the other Party under this
Agreement shall be in writing and signed by the Party giving such Consent. 
 Section 16.03 Severability. In the event any one
or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or
impaired thereby, and the Parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

power and authority to execute, deliver and perform this Agreement, that this Agreement has been duly authorized by all necessary corporate action on the part of such Party, that this Agreement constitutes a legal, valid and binding obligation of

Section 16.06 Complete Agreement; Construction. This Agreement shall constitute the entire agreement between the Parties with
respect to the subject matter hereof and shall supersede all previous negotiations, commitments, courses of dealing and writings with respect to such subject matter. All such other agreements shall be of no further effect between the

  
 26 

 
Parties, and any rights or obligations existing thereunder shall be fully and finally settled, calculated as of the date hereof. In the event of any inconsistency between this Agreement and the
Separation Agreement or any of the Ancillary Agreements, with respect to the subject matter hereof, the provisions of this Agreement shall control. 

Section 16.07 Title and Headings. Titles and headings to Sections are inserted for the convenience of reference only and are not
intended to be a part of or to affect the meaning or interpretation of this Agreement. 
 Section 16.08 No Double Recovery. No
provision of this Agreement shall be construed to provide an indemnity or other recovery for any costs, damages, or other amounts for which the damaged Party has been fully compensated under any other provision of this Agreement or under any other
agreement or Action at law or equity. Unless expressly required in this Agreement, a Party shall not be required to exhaust all remedies available under other agreements or at law or equity before recovering under the remedies provided in this
Agreement. 
 Section 16.09 Counterparts; Electronic Delivery. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which taken together shall be considered one and the same agreement, and, except as otherwise expressly provided in Section 10, shall become effective when one or more
such counterparts have been signed by each Party and delivered to each Party. Execution and delivery of this Agreement or any other documents pursuant to this Agreement by facsimile or other electronic means shall be deemed to be, and shall have the
same legal effect as, execution by an original signature and delivery in person. 
 Section 16.10 Governing Law. This Agreement
shall be governed by and construed in accordance with the internal laws, and not the Laws governing conflicts of Laws, of the State of Oklahoma.

Oklahoma, Tulsa Division (the “Oklahoma Courts”), for the purposes of any suit or Action or other proceeding in accordance with Article IX of the Separation Agreement or Section 13 herein or for provisional relief to
prevent irreparable harm, and to the non-exclusive jurisdiction of the Oklahoma Courts for the enforcement of any award issued thereunder. Each of the Parties further agrees that service of any process, summons, notice or document by United States
registered mail or receipted courier service to such Party’s respective address set forth in Section 16.01 shall be effective service of process for any Action, suit or proceeding in the Oklahoma Courts with respect to any
matters to which it has submitted to jurisdiction in this Section 16.11. Each of the Parties irrevocably and unconditionally waives any objection to the laying of venue of any Action, suit or proceeding arising out of this Agreement or

Court, and (iii) enforcement of any such award of an arbitral tribunal or an Oklahoma Court in any court of the United States, or any other any court or tribunal sitting in any state of the United States or in any foreign country that has

 Section 16.13 Waiver
of Jury Trial. Subject to Article IX of the Separation Agreement and Sections 13, 16.11 and 16.12 herein, each of the Parties hereby waives to the fullest extent permitted by applicable Law any right it may

expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it has been induced to enter into this Agreement and the transactions contemplated by this
Agreement, as applicable, by, among other things, the mutual waivers and certifications in this Section 16.13.

 Section 16.15 Certain Termination and Amendment Rights. This
Agreement may be terminated and the Distribution may be amended, modified or abandoned at any time prior to the Distribution Date and in the sole discretion of Parent without the approval of Spinco or the stockholders of Parent. In the event of such
termination, no Party shall have any liability of any kind to any other Party or any other Person. After the Distribution Date, this Agreement may not be terminated except by an agreement in writing signed by Parent and Spinco.

 28 

 Section 16.17 No Circumvention. The Parties agree not to directly or indirectly take
any actions, act in concert with any Person who takes an action, or cause or allow any member of such Party’s Group to take any actions (including the failure to take a reasonable action) such that the resulting effect is to materially
undermine the effectiveness of any provisions of this Agreement. 
 Section 16.18 Subsidiaries. Each of the Parties shall cause
to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary of such Party or by any entity that becomes a Subsidiary of such Party on and after the Effective
Date. The Parties acknowledge that certain actions, agreements and obligations that certain of their Affiliates and Subsidiaries may be required to perform in connection with the performance of the Parties’ obligations under this Agreement may
require Governmental Approval by Governmental Entities under applicable Law, and therefore agree that performance of such actions, agreements and obligations is subject to the receipt of all such necessary Governmental Approvals, which approvals
each Party shall, and shall cause the members of its respective Group to, use its commercially reasonable efforts to obtain. 

Section 16.19 Assignment. This Agreement shall not be assignable, in whole or in part, directly or indirectly, by either
Party without the prior written consent of the other Party, and any attempt to assign any rights or obligations arising under this Agreement without such consent shall be null and void; provided that a Party may assign this Agreement in
connection with a merger transaction in which such Party is not the surviving entity or the sale by such Party of all or substantially all of its assets; provided that the surviving entity of such merger or the transferee of such assets shall
agree in writing, reasonably satisfactory to the other Party, to be bound by the terms of this Agreement as if named as a “Party” hereto. In addition, in the event that any third Person or “group” (as such term is
used in Section 13(d) and 14(d) of the Exchange Act) acquires, including by way of merger, consolidation or other business combination, fifty percent or more of the consolidated assets or voting equity of either Parent or Spinco, such Party, as
