WHEREAS, in connection with the foregoing, the Company, ConocoPhillips, the Class P Members, Chevron and the Class C Member have
determined to enter into this Consent Agreement. 
 NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 
  

	1.	Notwithstanding Article 10 or any other provision of the LLC Agreement to the contrary, ConocoPhillips may, if ConocoPhillips determines to effect the Spin-off,
(i) have equity interest(s) in certain of the Class P Members transferred to SpinCo, to a wholly-owned Subsidiary of SpinCo or to a wholly-owned Subsidiary of COPCo, (ii) have Membership Interest(s) owned by certain of the Class P Members

	2.	Each of Chevron and the Class C Member hereby waives any right of first refusal with respect to the Class P Members’ Membership Interest pursuant to
Section 10.6 of the LLC Agreement and any other transfer rights or restrictions pursuant to Section 10.8 or any other provision of the LLC Agreement that would otherwise be applicable in the event that ConocoPhillips effects the Transfer.

  
 2 

	3.	Each of Chevron and the Class C Member hereby grants its consent to the Transfer and agrees to use commercially reasonable efforts to cooperate and execute, if
necessary, whatever documents may be reasonably required in order for ConocoPhillips to effect the Transfer. 

  

	4.	Each of the foregoing waivers, consents, and agreements of Chevron and the Class C Member is subject to the following conditions (the “Conditions”),
and this Consent Agreement shall not be effective until such conditions are met: 

  

	 	(a)	In the event that ConocoPhillips effects a transfer of Membership Interest owned by a Class P Member to SpinCo or to a wholly-owned Subsidiary of SpinCo or of COPCo
that is not already a Member at the time of such transfer (each, a “New Substitute Member”), each such New Substitute Member and each Class P Member shall have executed and delivered to Chevron and the Class C Member an amendment to
the LLC Agreement reflecting the admission of each such New Substitute Member and including an agreement in writing by the New Substitute Member to be bound by the LLC Agreement in substantially the form of Exhibit A hereto (each, a “New
Substitute Member Amendment”); 

  

	 	(b)	(i) Each of SpinCo and any wholly-owned Subsidiaries of SpinCo, to the extent the Membership Interest of the Class P Members is to be transferred to such Subsidiaries
pursuant to the Transfer, and (ii) each of the current Class P Members to the extent such Class P Members are to retain their direct Membership Interest pursuant to the Transfer, shall have executed and delivered to Chevron and the Class C
Member the Third Amended and Restated LLC Agreement of the Company in substantially the form attached as Exhibit B hereto (the “Third Amended and Restated LLC Agreement”); 

 

	 	(c)	Each of COPCo and SpinCo shall have executed and delivered to Chevron and the Company the Contribution Assumption Agreement in substantially the form attached as
Exhibit C hereto (the “Contribution Assumption Agreement”); and 

  

	 	(d)	Each of COPCo, ConocoPhillips and SpinCo shall have executed and delivered to Chevron the Environmental Assumption Agreement in substantially the form attached as
Exhibit D hereto (the “Environmental Assumption Agreement”). 

  

	 	(e)	 ConocoPhillips shall either, at ConocoPhillips’ option, (i) provide Chevron with written confirmation from a duly authorized officer of
ConocoPhillips that the financial status of SpinCo immediately prior to consummation of the Spin-Off has not materially worsened compared to that set forth in the documentation provided by ConocoPhillips to Chevron or the documentation filed with
the Securities and Exchange Commission, in each case, on or prior to the date hereof or (ii) provide 

  
 3 

	 	
Chevron with evidence that SpinCo has both a credit rating of Baa3 or higher (or the equivalent) from Moody’s Investors Service, Inc. (or any successor thereto) and a credit rating of BBB-
or higher (or the equivalent) from Standard & Poor’s Ratings Group (or any successor thereto) as of immediately prior to the Spin-off. 

  

	5.	The parties agree that any purported Transfer consummated without the satisfaction of the Conditions shall be void and shall be of no effect. 

 

	6.	With respect to each New Substitute Member, and concurrently with the satisfaction of the Condition set forth in Section 4(a) with respect to such New Substitute
Member, the Class C Member agrees to execute and deliver to the Class P Members the applicable New Substitute Member Amendment. 

  

	7.	Concurrently with the Transfer, and upon the satisfaction of the Conditions, (a) each of Chevron and the Class C Member agrees to execute and deliver to SpinCo and
the Class P Members the Third Amended and Restated LLC Agreement, (b) Chevron agrees to execute and deliver to COPCo and SpinCo the Contribution Assumption Agreement, (c) Chevron agrees to cause Unocal to execute and deliver to COPCo,
ConocoPhillips and SpinCo the Environmental Assumption Agreement and (d) the Company agrees to execute and deliver to COPCo, SpinCo and Chevron the Contribution Assumption Agreement. 

 

	8.	COPCo hereby waives any and all right to claim that the Transfer and the transactions contemplated by the Transfer is in breach of, results in a termination of any
rights under, or gives rise to any termination or other right becoming exercisable pursuant to or in connection with, the Tradename License Agreement (including, without limitation, the right to termination of the Tradename License Agreement set
forth in Section 8.2.2 of the Tradename License Agreement). Each of COPCo, Chevron and the Company agree that (a) the Tradename License Agreement shall continue to remain in full force and effect prior to and after the consummation of the
Transfer or any of the other transactions contemplated by the Transfer, except that upon consummation of the Transfer all of COPCo’s rights as “LICENSOR” pursuant to Section 8.2.2 of the Tradename License Agreement shall
terminate and be of no further force or effect and (b) the Tradename License Agreement shall continue in force regardless of whether COPCo’s Trademark (as defined in the Tradename License Agreement) registrations remain in force.

  

	9.	 ConocoPhillips represents and warrants that the Transfer shall not cause a termination of the Company under section 708 of the Code (a
“Termination”). If the Transfer causes a Termination, ConocoPhillips, as the sole remedy therefor, will reimburse and indemnify the Company and the Class C Member, and hold the Company and the Class C Member harmless from, all
liabilities, obligations, damages, losses, costs and expenses (including reasonable attorneys’ fees and court costs) arising as a direct or consequential result of such Termination (“Termination Losses”); provided that the
calculation of such 

  
 4 

	 	
Termination Losses shall (i) use an assumed discount rate of 10% and (ii) be on an after-tax basis, with an assumed tax rate of 38%. For the avoidance of doubt and without limiting the
generality of the foregoing, with respect to property held by the Company at the time of the Termination, the difference between the present value of (i) the deductions the Company would have been entitled to under Section 168 of the Code
had no such Termination occurred and (ii) the deductions the Company is entitled to under Section 168 of the Code following the Termination shall be considered Termination Losses. 

 

	10.	ConocoPhillips represents and warrants that the Transfer will not (a) violate any applicable federal or state securities laws or regulations, subject the Company
to registration as an investment company or election as a “business development company” under the Investment Company Act of 1940; (b) require any Member or any affiliate of a Member to register as an investment adviser under the
Investment Advisers Act of 1940; (c) violate any other federal, state or local laws; (d) cause the Company to be treated as an association taxable as a corporation for federal income tax purposes; (e) cause the Company or any Member
to be treated as an ERISA fiduciary; or (f) otherwise violate the LLC Agreement (each of the foregoing, a “Transfer Violation”). If the Transfer causes a Transfer Violation, ConocoPhillips will reimburse and indemnify the
Company and the Class C Member and hold the Company and the Class C Member harmless from all liabilities, obligations, damages, losses, costs and expenses (including reasonable attorneys’ fees and court costs) arising as a direct or
consequential result of such Transfer Violation, and such indemnification shall be on an after-tax basis with an assumed tax rate of 38%. 

  

	11.	ConocoPhillips shall promptly reimburse the Company for all third party fees and expenses incurred by the Company or any of its Subsidiaries in connection with the
Transfer, including, but not limited to, Transfer Taxes and legal fees and costs. “Transfer Tax” means any registration, stamp, recording, property, transfer or similar tax. 

 

	12.	From the date hereof until the consummation of the Spin-Off, ConocoPhillips agrees to provide Chevron with such proof of the investment intent and financial status of
SpinCo as Chevron may reasonably request. 

  

	13.	

  

	 	(a)	This Consent Agreement shall be governed by and construed under the substantive laws of the State of Delaware, without regard to Delaware choice of law provisions.

  

	 	(b)	 Each party hereto irrevocably submits to the jurisdiction of any Delaware state court or any federal court sitting in the State of Delaware in any
action arising out of or relating to this Consent Agreement, and hereby irrevocably agrees that all 

  
 5 

	 	
claims in respect of such action may be heard and determined in such Delaware state or federal court. Each party hereto hereby irrevocably waives, to the fullest extent it may effectively do so,
the defense of an inconvenient forum to the maintenance of such action or proceeding. The parties hereto further agree, to the extent permitted by law, that final and unappealable judgment against any of them in any action or proceeding contemplated
above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified copy of which shall be conclusive evidence of the fact and amount of such judgment.

  

	 	(c)	To the extent that any party hereto has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or
notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each party hereto hereby irrevocably waives such immunity in respect of its obligations with respect to this
Consent Agreement. 

  

	 	(d)	Each party hereto waives, to the fullest extent permitted by applicable laws, any right it may have to a trial by jury in respect of any action, suit or proceeding
arising out of or relating to this Consent Agreement. Each party hereto certifies that it has been induced to enter into this Consent Agreement by, among other things, the mutual waivers and certifications set forth above in this Section 12.

  

	14.	This Consent Agreement may be executed in multiple counterparts including through electronically exchanged signature pages (e.g., emailed PDFs or facsimile
transmissions), one for each of the parties hereto, and each of the counterparts when executed and delivered shall be deemed to be an original and all of such counterparts together shall constitute one and the same instrument.

  

	15.	This Consent Agreement shall automatically terminate if the Transfer is not consummated in accordance with this Consent Agreement prior to October 1, 2012 or, if
earlier, upon a public announcement by ConocoPhillips that it has abandoned the Spin-off.

 ARTICLE 8 
 CAPITAL CONTRIBUTIONS AND PERCENTAGE INTERESTS 
 8.1 CAPITAL
CONTRIBUTIONS AND PERCENTAGE INTERESTS. 
 (a) Effective as of the Closing, the Initial Chevron Member and each of the
Previous Phillips Members agreed (i) to make a Capital Contribution to the Company as contemplated by Article II of the Contribution Agreement and credit the Capital Account of the Initial Chevron Member and each Previous Phillips Member in
respect thereof in accordance with Section 8.1(b) of the Amended & Restated LLC Agreement, (ii) to determine the Percentage Interest of each Class C Member and each Class P Member in accordance with Section 8.1(a) of the
Amended & Restated LLC Agreement, and (iii) that (A) the aggregate Percentage Interests of all Class C Members shall equal 50% and the aggregate Percentage Interests of all Class P Members shall equal 50%, (B) such aggregate
Percentage Interests shall not change unless otherwise agreed by the Members, and (C) such aggregate Percentage Interests shall not be affected by the Chevron Pipe Line Contribution. 

(b) Effective as of the Closing, Chevron and Phillips agreed to (i) determine the balance of the Capital Account of the Initial
Chevron Member and each Previous Phillips Member as of the Closing Date in accordance with Section 8.1(c) of the Amended & Restated LLC Agreement, (ii) determine the Percentage Interest of the Initial Chevron Member and each
Previous Phillips Member as of the Closing Date in accordance with Section 8.1(c) of the Amended & Restated LLC Agreement, and (iii) agree to schedules setting forth the Carrying Values of assets specified in clause (i) of
the first sentence of Section 8.1(c) of the Amended & Restated LLC Agreement. 

  
 25 

 (c) The determination of Capital Account balances as described in Section 8.1(b) hereof
was designed to result in the aggregate credit balances in the Capital Accounts of the Class C Members being equal to the aggregate credit balances in the Capital Accounts of the Class P Members as of Closing and after giving effect to the
distributions described in Section 9.2(f) which is consistent with the agreement of the Initial Chevron Member and each of the Previous Phillips Members that the fair market value of the net assets contributed to the Company by the Class C
Members at Closing and the fair market value of the net assets contributed to the Company by the Class P Members at Closing were equal after giving effect to the distributions described in Section 9.2(f), and this result was not to be affected
by the Chevron Pipe Line Contribution. 
 8.2 ADDITIONAL CAPITAL CONTRIBUTIONS. No Member may make additional Capital
Contributions other than pursuant to its obligations under the Contribution Agreement or this Agreement without the consent of the Board of Directors. The Board of Directors shall approve all material terms of any such Capital Contribution,
including its effect on the Members’ relative Capital Accounts and Percentage Interests. Except as provided below, the Members intend that any capital requirements of the Company after the date hereof not satisfied by revenues generated from
the operations of the Company will be funded through additional Capital Contributions by the Members or loans from Members to the Company, in each case as approved by the Members and the Board of Directors. It is not anticipated that such future
capital requirements of the Company will be funded through the incurrence of indebtedness for borrowed money; provided that the foregoing shall not prevent (i) the entry into commercial cash management facilities, including but not
limited to corporate revolving credit facilities, commercial paper programs and accounts receivable securitization programs, solely for short term or general working capital purposes or (ii) project financing. Notwithstanding anything in this
Agreement to the contrary, in the event that any additional Capital Contributions by the Members or loans from Members to the Company are approved by the Members and the Board of Directors, no Tax Distributions shall be made with respect to the two
(2) Fiscal Quarters that end immediately after the date that each such additional Capital Contribution or loan is made (each such period, a “Suspension Period”). 

8.3 WITHDRAWAL OR REDUCTION OF CAPITAL CONTRIBUTIONS. 
 (a) Except as expressly provided in this Agreement, no Member shall have the right to withdraw from the Company all or any part of its Capital Contribution. 

(b) A Member, irrespective of the nature of its Capital Contribution, shall not have the right to demand and receive a distribution in
kind in return for its Capital Contribution, unless the Members shall have otherwise unanimously agreed. 
 8.4 NO RETURN ON
OR OF CAPITAL CONTRIBUTIONS. No amounts shall be payable on, with respect to, or in return of, Capital Contributions or Capital Accounts of Members except as expressly provided in this Agreement. 

8.5 CAPITAL ACCOUNTS. A single Capital Account shall be maintained for each Member (regardless of the class of interests owned by
such Member and regardless of the time or 

  
 26 

 
manner in which such interests were acquired) in accordance with the capital accounting rules of section 704(b) of the Code and the Income Tax Regulations thereunder (including without limitation
section 1.704-1(b)(2)(iv) of the Income Tax Regulations) and as further described in this Section 8.5. 
 (a) There shall
be established for each Member a Capital Account reflecting the excess (or deficit) of (a) the sum of (i) the Carrying Value of assets contributed to the Company by such Member and the amount of cash contributed to the Company by such
Member under Section 8.1 or Section 8.2 or paid pursuant to a note contributed to the Company by such Member, (ii) such Member’s share of Net Profits calculated in accordance with Section 9.1 and any items in the nature of
income or gain that are specifically allocated to such Member under Section 9.1, and (iii) the amount of any Company liabilities assumed by such Member or which are secured by any property distributed to such Member over (b) the sum
of (i) such Member’s share of Net Losses under Section 9.1 and any items in the nature of losses or expenses that are specifically allocated to such Member under Section 9.1, (ii) any distributions to such Member under
Section 9.2 or Section 12.6, and (iii) liabilities of such Member assumed by the Company or which are secured by any property contributed by such Member. In determining the amount of any liability for purposes of this section, there
shall be taken into account section 752(c) of the Code and any other applicable provisions of the Code and Income Tax Regulations. 
 (b) In the event of a transfer of all or any portion of a Member’s interest in the Company pursuant to Article 10 hereof, the Capital Account of any transferee shall include the appropriate portion
of the Capital Account of the Member from which the transferee’s interest in the Company was obtained. 
 (c) When Company
property is distributed in kind (whether in connection with liquidation and dissolution or otherwise), the Capital Accounts of the Members shall first be adjusted to reflect the manner in which the unrealized income, gain, loss and deduction
inherent in such property (that has not been reflected in the Capital Account previously) would be allocated among the Members if there were a taxable disposition of such property for the fair market value of such property (taking into account
section 7701(g) of the Code) on the date of distribution. 
 (d) The appropriate Officers shall make or cause to be made all
necessary adjustments in each Member’s Capital Account as required by the capital accounting rules of section 704(b) of the Code and the regulations thereunder. 
 8.6 LOANS BY MEMBERS TO THE COMPANY. No Member shall be obligated to lend money to the Company. No Member may lend money to the Company without the consent of the Board of Directors. The Board of
Directors shall approve all material terms of such a loan, including, without limitation, the interest rate and term. Any loan by a Member to the Company with the required consent of the Board of Directors shall be separately entered on the books of
the Company as a loan to the Company and not as a Capital Contribution, and shall be evidenced by a promissory note duly executed by at least one Class C Director and one Class P Director on behalf of the Company and delivered to the lending Member.

 8.7 TREATMENT OF CERTAIN INDEMNITY PAYMENTS. 

(a) If Company makes any payment to a third party that is subject to indemnification by a Class C Member, a Class P Member or a Previous
Phillips Member (or any Affiliate thereof) pursuant to the Contribution Agreement or Annex B or C thereto (a “Company Indemnifiable Payment”), the Members intend such payment to be treated as preserving the value of the contribution made
pursuant to Article II of the Contribution Agreement by the Member liable for the indemnity payment. Toward that end, each indemnity obligation arising in respect of a Company Indemnifiable Payment will be treated as having arisen immediately prior
to such contribution of assets by the Indemnifying Party, the Indemnifying Party will be treated as if it had originally contributed assets with a Carrying Value increased by the amount of the Company Indemnifiable Payment, and the Company will be
treated as having assumed an additional liability in the amount of the Company Indemnifiable Payment. As a result, the amounts credited to the Capital Accounts of the Class C Members in the aggregate and the Class P Members in the aggregate will
remain equal. The Members also intend that the tax consequences of such Company Indemnifiable Payment and the indemnification payment itself shall inure to the Indemnifying Party, but, except as otherwise agreed by the Members, only to the extent
that such tax result can be achieved without causing the Capital Accounts of the Class C Members in the aggregate and the Capital Accounts of the Class P Members in the aggregate to fail to be equal. 

(b) If a Member or a Previous Phillips Member makes any payment to a third party that is subject to indemnification by the Company
pursuant to the Contribution Agreement or Annex B or C thereto (a “Member Indemnifiable Payment”), the Members intend that the tax consequences of such Member Indemnifiable Payment and the indemnification payment itself shall inure to the
Company and be shared by the Members in accordance with their respective Percentage Interests, but, except as otherwise agreed by the Members, only to the extent that such tax results can be achieved without causing the Capital Accounts of the Class
C Members in the aggregate and the Capital Accounts of the Class P Members in the aggregate to fail to be equal. 
 8.8
TREATMENT OF CERTAIN DEFERRED CAPITAL CONTRIBUTIONS. As a result of the K-Resin Accident, the value of certain assets contributed by the Previous Phillips Members at Closing had declined from that which existed when the Initial Chevron Member
and the Previous Phillips Members were first agreeing on the economic terms of the arrangement described in this Agreement. The Initial Chevron Member and the Previous Phillips Members could not agree on the amount of the decline in value, in part
because they were unable to reach an agreement on the likely time and expense involved in repairing the damage caused by the K-Resin Accident and the degree and permanence of any loss of customers that the K-Resin Accident may cause. In order to
resolve the issue, it was agreed that one or more of the Class P Members might have to make capital contributions to the Company after the Closing under the circumstances and in the amounts calculated under the provisions of the Contribution
Agreement. The Members view such deferred capital contributions as necessary to preserve the pre K-Resin 

  
 28 

 
Accident value of the business and assets contributed by the Class P Members. The Members agree that any deferred contributions are capital contributions and will not be reported as income by the
Company. 
 8.9 SPECIAL RULE. An Indemnifying Party will indemnify the Indemnified Party on a Net After-Tax Basis against
any income or franchise tax incurred in the event that any indemnification payment is treated as taxable income to the Indemnified Party. For purposes of this paragraph, “Net After-Tax Basis” means after any U.S. federal, state or local
income or franchise taxes (computed using the Tax Rate) incurred as a result of such indemnification (assuming the deductibility of such state and local income and franchise taxes in calculating federal income tax), reduced by any tax benefit
arising as a result of such indemnification. 
 8.10 APPLICATION OF THE BASKET, TAX BASKET AMOUNT AND CAP. No provision
of this Agreement or the Contribution Agreement (including the Annexes thereto) shall be applied or interpreted in a manner that would cause any indemnification payment to be made that otherwise would not be payable because of application of the
Basket, Tax Basket Amount or the Cap. 
 ARTICLE 9 

ALLOCATION OF PROFITS AND LOSSES; DISTRIBUTIONS; TAX AND ACCOUNTING MATTERS 

9.1 ALLOCATIONS. Net Profit and Net Loss of the Company shall be determined and allocated with respect to each Fiscal Year, Fiscal
Quarter or other period of the Company as follows: 
 (a) GENERAL ALLOCATION. Except as otherwise provided in this Article 9,
Net Profit and Net Loss for each Fiscal Year, Fiscal Quarter or other period shall be allocated to the Members in accordance with their Percentage Interests. 
 (b) REGULATORY ALLOCATIONS. Notwithstanding the foregoing, the following special allocations shall be made for each Fiscal Year or other period in the following order of priority: 

(i) If there is a net decrease in Company Minimum Gain during a Company taxable year, then each Member shall be allocated
items of Company income and gain for such taxable year (and, if necessary, for subsequent years) in an amount equal to such Member’s share of net decrease in Company Minimum Gain, determined in accordance with section 1.704-2(g)(2) of the
Income Tax Regulations. This subsection (b)(i) is intended to comply with the minimum gain chargeback requirement of section 1.704-2(f) of the Income Tax Regulations and shall be interpreted consistently therewith. 

  
 29 

 (ii) If there is a net decrease in Member Nonrecourse Debt Minimum Gain
attributable to a Member Nonrecourse Debt during any Company taxable year, each Member who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with section 1.704-2(i)(5) of
the Income Tax Regulations, shall be specially allocated items of Company income and gain for such taxable year (and, if necessary, subsequent years) in the amount equal to such Member’s share of net decrease in Member Nonrecourse Debt Minimum
Gain attributable to such Member Nonrecourse Debt, determined in a manner consistent with the provisions of section 1.704-2(i)(4) of the Income Tax Regulations. This subsection (b)(ii) is intended to comply with the partner nonrecourse debt minimum
gain chargeback requirement of section 1.704-2(i)(4) of the Income Tax Regulations and shall be interpreted consistently therewith. 
 (iii) If any Member unexpectedly receives (or Members unexpectedly receive) an adjustment, allocation or distribution of the type contemplated by section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) of
the Income Tax Regulations, items of income and gain shall be allocated to such Member (or if more than one Member receives such an adjustment, allocation or distribution, items of income and gain shall be allocated to such Members in proportion to
the amounts of their respective Adjusted Capital Account Deficits) in an amount (or amounts) and manner sufficient to eliminate the Adjusted Capital Account Deficit of such Member (or deficits of such Members) as quickly as possible. It is intended
that this subsection (b)(iii) qualify and be construed as a “qualified income offset” within the meaning of section 1.704-1(b)(2)(ii)(d) of the Income Tax Regulations. 

(iv) If the allocation of Net Loss to a Member as provided in Section 9.1(a) would create or increase an Adjusted
Capital Account Deficit and one or more other Members would have a positive Capital Account balance, there shall be allocated to such Member only that amount of Net Loss as will not create or increase an Adjusted Capital Account Deficit. The Net
Loss that would, absent the application of the preceding sentence, otherwise be allocated to such Member shall, subject to the Adjusted Capital Account Deficit limitations of such sentence, be allocated to those Members having positive Capital
Account balances up to the amount of such positive Capital Account balances in the ratios that each such Member’s positive Capital Account Balance bears to the sum of such positive Capital Account balances. To the extent that allocations of Net
Losses have been made pursuant to this subsection (b)(iv), future allocations of Net Profits, notwithstanding anything to the contrary in this Agreement, shall be made first to restore such Net Losses. 

(v) Member Nonrecourse Deductions for any Fiscal Year or other period shall be allocated each year to the Member that
bears the economic risk of loss (within the meaning of section 1.752-2 of the Income Tax Regulations) for the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable. 

  
 30 

 (vi) Nonrecourse Deductions for any Fiscal Year or other period shall be
allocated to the Members in proportion to their respective Percentage Interests. 
 (vii) To the extent an
adjustment to the adjusted tax basis of any Company asset, pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4) of the Income Tax Regulations, to be
taken into account in determining Capital Accounts as the result of a distribution to a Member in complete liquidation of such Member’s interest in the Company, the amount of such adjustment to Capital Accounts shall be treated as an item of
gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members in accordance with their interests in the Company in the event section
1.704-1(b)(2)(iv)(m)(2) of the Income Tax Regulations applies, or to the Member to whom such distribution was made in the event section 1.704-1(b)(2)(iv)(m)(4) of the Income Tax Regulations applies 

(viii) The allocations set forth in subsections (b)(i) through (b)(vii) (the “Regulatory Allocations”) are
intended to comply with certain requirements of sections 1.704-1(b), 1.704-2(f) and 1.704-2(i) of the Income Tax Regulations. Notwithstanding the provisions of Section 9.1(a), the Regulatory Allocations shall be taken into account in allocating
other items of income, gain, loss and deduction among the Members so that, to the extent possible, the net amount of such allocations of other items and the Regulatory Allocations to each Member shall be equal to the net amount that would have been
allocated to each Member if the Regulatory Allocations had not occurred. 
 (c) TAX ALLOCATIONS. 

(i) Except as provided in subsection (c)(ii), for income tax purposes under the Code and the Income Tax Regulations,
Company taxable income and loss shall be allocated to each Member in the same manner that Company Net Profit and Net Loss (and items entering into the determination thereof) are allocated. 

(ii) SECTION 704(C). In accordance with section 704(c) of the Code and the Income Tax Regulations thereunder, income,
gain, loss and deduction with respect to any property contributed to the capital of the Company shall, solely for income tax purposes, be allocated so as to take account of any variation between the adjusted basis of such property to the Company for
federal income 

  
 31 

 
tax purposes and the initial Carrying Value of such property. If the Carrying Value of any Company property is adjusted as described in the definition of “Carrying Value”, subsequent
allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and the Carrying Value of such asset in the manner prescribed
under Sections 704(b) and 704(c) of the Code and the Income Tax Regulations thereunder. With respect to assets contributed or required to be contributed by the Initial Chevron Member, [SpinCo] and the Previous Phillips Members at the Closing
pursuant to the Contribution Agreement, for purposes of applying section 704(c) of the Code and this Section 9.1(c)(ii), the Company shall use the traditional method with curative allocations set forth in section 1.704-3(c) of the Income Tax
Regulations. Any elections or other decisions relating to such allocations shall be made by the Board of Directors. 
 (d)
DEPRECIATION RECAPTURE. Solely for tax purposes, a Member’s share of the Company’s depreciation recapture recognized for tax purposes upon the disposition of Company property shall be computed in the manner provided for in sections
1.704-3(a)(11), 1.1245-1(e) and 1.1250-1(f) of the Income Tax Regulations. The provisions of this Section 9.1(d) are intended to affect only the character of the items of gain allocated by the Company to the Members. This Section 9.1(d)
shall not affect the aggregate amount of gain (including gain characterized under this Section 9.1(d) as depreciation recapture) otherwise allocable to a Member pursuant to this Section 9.1. 

(e) CHANGE IN PERCENTAGE INTERESTS. Except as otherwise required by law, if the Percentage Interests of the Members of the Company are
changed during any taxable year, all items to be allocated to the Members for such entire taxable year shall be prorated on the basis of the portion of such taxable year which precedes each such change and the portion of such taxable year on and
after each such change according to the number of days in each such portion, and the items so allocated for each such portion shall be allocated to the Members in the manner in which such items are allocated as provided in Section 9.1(a) during
each such portion of the taxable year in question. 
 (f) EXCESS NONRECOURSE LIABILITIES. Nonrecourse liabilities of the Company
that constitute “excess nonrecourse liabilities” within the meaning of section 1.752-3(a)(3) of the Income Tax Regulations, shall be allocated among the Members in proportion to their respective Percentage Interests. 

(g) [INTENTIONALLY OMITTED] 
 (h) ALLOCATIONS RELATING TO CAPITAL TRANSACTIONS. In connection with the sale or other disposition of all or substantially all of the assets of the Company (including upon liquidation of the Company),
items of income, gain, loss and deduction shall, except as otherwise required by subsections (b) through (f) above, be allocated to the Members 

  
 32 

 
in the following manner: in such amounts as shall cause (A) the ratio of the Capital Account of each Member to the aggregate Capital Accounts of all Members to (B) equal as nearly as
possible each Member’s respective Percentage Interest. 
 (i) STATE AND LOCAL ITEMS. Items of income, gain, loss,
deduction, credit and tax preference for state and local income tax purposes shall be allocated to and among the Members in a manner consistent with the allocation of such items for federal income tax purposes in accordance with the foregoing
provisions of this Section 9.1. 
 9.2 DISTRIBUTIONS. 

(a) Subject to Section 8.2 hereof, the Company shall distribute to each Member as promptly as practicable (and in any event within
forty-five (45) days) after the end of each of the first three (3) Fiscal Quarters of each Fiscal Year of the Company an amount equal to such Member’s Quarterly Tax Distribution for such Fiscal Quarter. In addition, subject to
Section 8.2 hereof, the Company shall distribute to each Member as promptly as practicable (and in any event within forty-five (45) days) after the end of each Fiscal Year an amount equal to the excess, if any, of such Member’s
Proportionate Tax Share for such Fiscal Year over the aggregate amount of Quarterly Tax Distributions made to such Member with respect to such Fiscal Year; provided that, if a Suspension Period occurs during such Fiscal Year, such calculation shall
exclude any Adjusted Taxable Income attributable to Fiscal Quarters within such Suspension Period; provided further that, if Section 9.2(b) ceases to prevent Tax Distributions pursuant to this Section 9.2(a) during a Fiscal Year, the
calculation of the Tax Distribution to be made with respect to such Fiscal Year pursuant to the second sentence of this Section 9.2(a) shall also exclude any Adjusted Taxable Income attributable to Fiscal Quarters in such Fiscal Year that ended
prior to the date when Section 9.2(b) ceased to prevent such Tax Distributions. 
 (b) Notwithstanding
anything herein to the contrary, in no event shall the Company make any Tax Distribution pursuant to Section 9.2(a) until the date upon which each of (i) the $300,000,000 7% Senior Notes due 2014, (ii) the $400,000,000 8  1/4% Senior Notes due 2019 and (iii) the
$300,000,000 4.75% Senior Notes due 2021, each issued by the Company and Chevron Phillips Chemical Company LP as joint and several obligors (collectively, the “Bond Indebtedness”), has been repaid or redeemed in full or such repayment
obligations otherwise have been fully discharged. The Class C Member and each of the Class P Members agree to cause the Class C Directors and the Class P Directors, respectively, to instruct management of the Company to use commercially reasonable
efforts to repay or redeem the Bond Indebtedness, as promptly as commercially practicable after the date hereof, with available cash of the Company in the manner most beneficial to the Company in management’s discretion. 

(c) Any distributions by the Company to the Members, other than a Tax Distribution in accordance with Sections 9.2(a) and 9.2(b) hereof,
shall be payable at the discretion of the Board of Directors. 

  
 33 

 (d) To the extent the Company is required by law to withhold or to make tax payments on
behalf of or with respect to any Member, the Company may withhold such amounts and make such tax payments as so required. For purposes of this Agreement, any such payments or withholdings shall be treated as a distribution to the Member on behalf of
whom the withholding or payment was made. 
 (e) Notwithstanding anything to the contrary contained in this Section 9.2,
the Company shall not make any distribution to the Members which would render the Company insolvent or which is otherwise prohibited by applicable law. 
 (f) Subsequent to the Closing, the Company made distributions to the Initial Chevron Member and the Previous Phillips Members as provided in Section 9.2(f) of the Amended & Restated LLC
Agreement, and, after such distributions, the aggregate Capital Accounts of the Class C Members remained equal to the aggregate Capital Accounts of the Class P Members. The Company will use its best efforts to avoid taking any action that, or
failing to take any action the failure of which to take, is likely to cause all or part of the distributions made pursuant to Section 9.2(f) of the Amended & Restated LLC Agreement to be taxable to one or more of the Members and in
connection therewith the Members shall cooperate with the Company and each other. 
 (g) In the event that, within two years of
the Closing or any contribution of an asset to the Company, the Members desire for the Company to make a distribution or payment to any of the Members or pay all or a portion of any liability, and if such distribution or payment to a Member or such
payment of a liability may give rise to a disguised sale under section 707(a)(2)(B) of the Code or corresponding provision of state or local law, the Members shall cooperate to avoid such result without changing the intended economics of the
arrangement. 
 (h) FORMATION AND REIMBURSEMENT FOR CAPITAL EXPENDITURES. 

(i) The Initial Chevron Member and the Previous Phillips Members intended that the contributions of P Chem (as defined in
the Contribution Agreement) and C Chem (as defined in the Contribution Agreement) constitute a nonrecognition transaction pursuant to Section 721(a) of the Code, and the Initial Chevron Member and the Previous Phillips Members reported and
caused the Company to report and otherwise treat the transfers of P Chem and C Chem to the Company as solely a nonrecognition transaction pursuant to Section 721(a) of the Code on all relevant tax returns and reports. Each Class P Member states
that it has made capital expenditures that are eligible for reimbursement pursuant to Regulations Section 1.707-4(d) (“Reimbursable Capital Expenditures”) with respect to P Chem in an amount that is not less than the amount set forth
opposite its name on Schedule 3 attached hereto, and the Class C Member states that it has made Reimbursable Capital Expenditures with respect to C Chem in an amount that is not less than the amount set forth opposite its name on Schedule 3 attached
hereto. 

  
 34 

 (ii) If, absent this Section 9.2(h), any distribution to a Class P
Member would cause any of the P Chem property transferred by a Previous Phillips Member to the Company pursuant to the Contribution Agreement to be treated as a sale of such property, or if, absent this Section 9.2(h), any distribution to a
Class C Member would cause any of the C Chem property transferred by that Member to the Company pursuant to the Contribution Agreement to be treated as a sale of such property, then, to the extent permitted by Regulations Section 1.707-4(d),
the Company and the Members shall treat such distribution as a reimbursement of Reimbursable Capital Expenditures made by such Person (up to the amount thereof as set forth on Schedule 3 less any portion of such amount that has been reimbursed by
any prior distribution treated as a reimbursement of Reimbursable Capital Expenditures under this Section 9.2(h)). 
 (iii) Without limiting the generality of the foregoing Section 9.2(h)(ii), if, absent this Section 9.2(h), any distribution to a Member would cause any of the property transferred by that Member
(or in the case of a Class P Member any property transferred by a Previous Phillips Member) to the Company pursuant to the Contribution Agreement to be treated as a sale of such property, then, to the extent permitted by Regulations
Section 1.707-4(d), the Members and the Company shall treat (i) any excess of any of the distribution to a Class C Member of the Initial Financing required by Section 9.2(f) of the LLC Agreement and Section 6.16 of the
Contribution Agreement and any distribution in respect of Actual Contributed Cash and/or Working Capital Difference required by Section 3.3 of the Contribution Agreement (collectively, the “Special Distribution”) over the Class C
Member’s “allocable share” (within the meaning of Regulations Section 1.707-5(b)) of the Interim Financing or other borrowing of the Company, the proceeds of which are allocable (within the meaning of Regulations
Section 1.707-5(b) and Notice 89-35, 1989-1 C.B. 675) to such Special Distribution, as reimbursements of Reimbursable Capital Expenditures incurred by such Class C Member (up to the amount thereof as set forth on Schedule 3 less any portion of
such amount that has been reimbursed by any prior distribution treated as a reimbursement of Reimbursable Capital Expenditures under this Section 9.2(h)), and (ii) any excess of the Special Distribution to a Class P Member over the Class P
Member’s “allocable share” (within the meaning of Regulations Section 1.707-5(b)) of the Interim Financing or other borrowing of the Company, the proceeds of which are allocable (within the meaning of Regulations
Section 1.707-5(b) and Notice 89-35, 1989-1 C.B. 675) to such Special Distribution, as reimbursements of Reimbursable Capital Expenditures incurred by such Class P Member (up to the amount thereof as set forth on Schedule 3 less any portion of
such amount that has been reimbursed by any prior distribution treated as a reimbursement of Reimbursable Capital Expenditures under this Section 9.2(h)).

EFFECT OF TRANSFER WITHOUT APPROVAL. Any purported Transfer of all or any part of a Member’s Membership Interest, or any interest therein, which is not in compliance with this Article 10 shall be void and, except as provided for in
Section 10.5, below, shall be of no effect. 
 10.5 LIABILITY FOR BREACH. Notwithstanding anything to the contrary
in this Article 10, any Member purporting to Transfer its Membership Interest, or any part thereof, in violation of this Article 10 shall be liable to the Company and the other Members for all liabilities, obligations, damages, losses, costs and

by non-compliance with any of the requirements and conditions provided for in Section 10.2. 
 10.6 PERMITTED TRANSFERS
SUBJECT TO RIGHT OF FIRST REFUSAL. 
 (a) At any time the Class C Member(s) or the Class P Member(s) (a “Transferring
Class”) may Transfer not less than all of their respective Class Membership Interest to a Person for cash, subject to the Right of First Refusal provided for in this Section 10.6 and the last sentence of Section 10.2. 

(b) In the event that any Transferring Class has received a bona fide written cash offer, which such Transferring Class is willing to
accept, for the Transferring Class to sell not less than all of its respective Class Membership Interest (the “Transferred Interest”) to any Person, the Transferring Class shall deliver a written notice (the “Transfer Notice”) to
all of the Members, other than the Members in the Transferring Class (the “Non-Transferring Class”), stating the Transferring Class’s intent to sell the Transferred Interest pursuant to a bona fide cash

  
 38 

 
offer. The Transfer Notice shall (i) specify the purchase price for and other material terms with respect to the sale of the Transferred Interest, (ii) identify the proposed purchaser
of the Transferred Interest, (iii) specify the date scheduled for the transfer (which date shall not be earlier than one hundred twenty (120) days from the date the Transfer Notice is delivered), (iv) contain a statement that the
offer has been accepted pending compliance with the right of first refusal set forth herein and receipt of required regulatory and other approvals, and (v) shall have attached thereto a copy of the written offer containing all of the terms and
conditions on which the Transferred Interest is to be sold. 
 (c) The Non-Transferring Class shall have the exclusive option to
purchase all (but not less than all) of the Transferred Interest on terms and conditions substantially the same in all material respects as, and at the same price, set forth in the written offer delivered pursuant to subsection (b) above. The
Non-Transferring Class shall notify the Company and the Transferring Class of its intention to exercise or not to exercise the right of first refusal hereunder within forty-five (45) days of receipt by the Non-Transferring Class of a Transfer
Notice. 
 (d) In the event that the Non-Transferring Class shall have duly elected to purchase the Transferred Interest (the
“Electing Class”), the Electing Class and the Transferring Class shall diligently pursue obtaining all regulatory approvals and use best commercially reasonable efforts to consummate the closing of the purchase of the Transferred Interest
as soon as practicable and in any event within one year from receipt of the Transfer Notice; provided that, if such closing does not occur within such one-year period due to the failure to obtain any required regulatory approvals, the
Electing Class’s right to close such sale may be extended at the option of the Electing Class, until such regulatory approvals are obtained, but in no event for a period of greater than one additional year. In the event of a failure of the
Non-Transferring Class to elect to purchase all of the Transferred Interest or a failure of the Electing Class to consummate such purchase in accordance herewith, the Transferring Class will be free, at any time within 120 days from the date the
Non-Transferring Class elect not to exercise their purchase rights hereunder or from the date the time periods specified in this section for such election have expired, subject, in each case, to extension for up to an additional eight
(8) months to the extent necessary to achieve any required regulatory approvals, to consummate the sale of the Transferred Interest to the purchaser at a price and upon terms and conditions no more favorable to the purchaser than those
specified in the Transfer Notice; provided that the purchaser shall assume all of the liabilities and obligations of the Transferring Class under this Agreement by a binding written instrument which shall be enforceable by the Company and the
Non-Transferring Class. 
 (e) A Transferring Class shall not be relieved of any of its obligations arising under this Agreement
prior to such Transfer. The Transferring Class and any transferee shall execute such documents as the Non-Transferring Class shall reasonably request to evidence the Transfer and the assumption and continuing obligations under this Agreement.

 (f) At the request of a Member, the Company will provide prospective purchasers of such Member’s Class Membership
Interest with reasonable access to financial, operating and other information of the Company, subject to customary confidentiality agreements which shall 

  
 39 

 
include provisions to protect competitively sensitive information. Each Member shall cooperate with, and shall not oppose, the closing of any Transfer which is in Compliance with this
Section 10.6. 
 10.7 PERMITTED TRANSFERS AMONG WHOLLY-OWNED AFFILIATES. Notwithstanding anything contained herein
to the contrary, any Member may Transfer all or any portion of its Membership Interest to a Wholly-Owned Affiliate of such Member, and such Transfer shall be deemed automatically approved by the Board of Directors; provided, however, that
such Transfer otherwise meets the conditions and requirements of Sections 10.2 and 10.3. 
 10.8 TRANSFERS OF EQUITY
INTERESTS IN A MEMBER. A sale, assignment, transfer or hypothecation of any direct or indirect equity interest in a Member by a Parent of such Member shall be deemed to be a Transfer by that Member of its Membership Interest in the Company for
purposes of this Article 10 and shall not be permitted except in accordance with the terms and conditions set forth in this Article 10. Chevron and [SpinCo] shall comply with this Section 10.8 and shall take all necessary action to cause their
Affiliates to comply with this Section 10.8. For the purpose of clarification of this Section 10.8, a Change of Control of the Ultimate Parent of any Member shall not be considered a Transfer of such Member’s Membership Interest or a
Transfer of the equity interest in such Member pursuant to this and the foregoing sections of this Article 10; provided, that a Change of Control of [SpinCo] shall be subject to the provisions of Section 10.10 hereof. 

10.9 CREDIT RATINGS BUY-OUT OPTION. 
 (a) Notwithstanding anything to the contrary in this Agreement, if any of the Members of one class or the Ultimate Parent of any of the Members of one class (the Member(s) of such class, the
“Downgraded Members”) concurrently have both an S&P Triggering Credit Rating and a Moody’s Triggering Credit Rating (a “Credit Rating Event”), the Member(s) of the other class (the “Buy-Out Members”) may, by
delivering written notice (a “Valuation Notice”) to the Downgraded Members following such Credit Rating Event in accordance with Section 10.9(b) below, require that the Members determine the Fair Market Value of the Membership
Interests of the Downgraded Members in accordance with Section 10.9(c) below. The Downgraded Members each agree to give written notice to the Buy-Out Members within five (5) days of any Credit Rating Event. 

(b) Upon the first occurrence of a Credit Rating Event for the Downgraded Members (an “Initial Credit Rating Event”), the
Buy-Out Members shall not be entitled to deliver a Valuation Notice unless a Downgraded Member or its Ultimate Parent has had either an S&P Triggering Credit Rating or a Moody’s Triggering Credit Rating continuously for three hundred
sixty-five (365) days from the beginning of the Initial Credit Rating Event (the “Initial Cure Period”). If each Downgraded Member and each Downgraded Member’s Ultimate Parent no longer has an S&P Triggering Credit Rating and
no longer has a Moody’s Triggering Credit Rating after an Initial Credit Rating Event (a “Cure Event”), and another Credit Rating Event occurs with respect to any such Downgraded Member or any such Downgraded Member’s Ultimate
Parent within twenty-four (24) months following the date of the most recent Cure Event 

  
 40 

 
(a “Subsequent Credit Rating Event”), the Buy-Out Members shall not be entitled to deliver a Valuation Notice hereunder unless a Downgraded Member or its Ultimate Parent has had either
an S&P Triggering Credit Rating or a Moody’s Triggering Credit Rating continuously for the following number of days following such Subsequent Credit Rating Event: (i) three hundred sixty-five (365) days minus the sum of
(ii) the number of days between the beginning of an Initial Credit Rating Event and the Cure Event associated with such Initial Credit Rating Event and (iii) the number of days between the beginning of each other Subsequent Credit Rating
Event and the Cure Event associated with each such other Subsequent Credit Rating Event (a “Subsequent Cure Period”); provided, however, that if at least twenty-four (24) months elapse after a Cure Event and before the next Credit
Rating Event, such Credit Rating Event will be deemed to be an Initial Credit Rating Event hereunder; provided further, however, that if no Cure Event occurs during the Initial Cure Period (including the Initial Cure Period following a Credit Rating
Event deemed an Initial Credit Rating Event hereunder) or during any Subsequent Cure Period, as applicable, with respect to a Credit Rating Event (such Credit Rating Event, a “Uncured Credit Rating Event”), the Buy-Out Members may deliver
a Valuation Notice at any time within ninety (90) days following the expiration of any such period. For the avoidance of doubt, after the occurrence of an Uncured Credit Rating Event for the Downgraded Members, the Buy-Out Members may deliver a
Valuation Notice at any time within ninety (90) days following the occurrence of a Subsequent Credit Rating Event with respect to such Downgraded Members (other than (x) during the time the Fair Market Value is being determined pursuant to
Section 10.9(c), (y) during the Buy-Out Interest Option Period or (z) after the exercise of the Buy-Out Interest Option, unless such exercise is terminated by the Purchaser (as defined below) in accordance with Section 10.11(a),
in each case of (x), (y) and (z), due to a previously delivered Valuation Notice by the Buy-Out Members); provided, however, that if at least twenty-four (24) months elapse after the Cure Event associated with the Uncured Credit Rating
Event and before the next Credit Rating Event, such Credit Rating Event will be deemed to be an Initial Credit Rating Event hereunder. 
 (c) The “Fair Market Value” of the relevant Membership Interests shall be: 
 (i) the amount agreed between the Class C Member and [SpinCo] after negotiating in good faith for no more than thirty (30) days after notice having been served requiring that the Members determine
the Fair Market Value of the relevant Membership Interests in accordance with Sections 10.9(a) and 10.9(b) or Section 10.10(a) hereof, as the case may be; or 

(ii) in the event that the Class C Member and [SpinCo] are unable to agree on the Fair Market Value of the relevant
Membership Interests within such period, each shall appoint, within ten (10) days following the expiration of the thirty (30) day period referred to in Section 10.9(c)(i), a nationally recognized investment bank to act for the
appointing party to determine the fair market value of the relevant Membership Interests as promptly as possible and in any event within thirty (30) days following the expiration of the above mentioned ten (10) day period. In the event the
Class C Member or [SpinCo] fails to timely appoint 

  
 41 

 
such an investment bank, the party that has timely appointed such an investment bank shall be entitled, at such party’s option, either (A) to have the investment bank it appointed
determine the fair market value of the relevant Membership Interests, which determination shall be final and binding on the Members or (B) to petition the Delaware Court of Chancery to have the Chancellor of such court (or his designee)
promptly appoint a second such investment bank. Each investment bank appointed pursuant to this Section 10.9(c) shall be instructed to determine the fair market value of the relevant Membership Interests by determining the value of fifty
percent (50%) of the aggregate Membership Interests of the Class C Member and Class P Members, without a control premium and with valuation premised on a sale in an arm’s length transaction where neither the seller nor the buyer is under
compulsion to consummate the sale. If the lower of the two values determined by the two investment banks is no more than 10% lower than the greater value, then the Fair Market Value of the relevant Membership Interests shall be the average of the
two values. If the lower value is more than 10% lower than the greater value, then the Class C Member and [SpinCo] shall direct the two (2) investment banks to promptly (and not later than ten (10) days following the delivery of the last
of the two (2) valuations prepared by such investment banks) appoint a third nationally recognized investment bank to determine the fair market value of the relevant Membership Interests. In the event the two (2) investment banks fail to
timely appoint such a third investment bank, either the Class C Member or [SpinCo] shall be entitled to petition the Delaware Court of Chancery to have the Chancellor of such court (or his designee) promptly appoint a third such investment bank. If
the value determined by such third investment bank is within the range of the first two values, then the fair market value of the relevant Membership Interests as determined by such third investment bank shall be the Fair Market Value of the
relevant Membership Interests. If the value determined by such third investment bank is outside the range of the first two values, then the Fair Market Value of the relevant Membership Interests shall be the median of the three values. Each of the
Class C Member and [SpinCo] shall pay the costs and fees for the investment bank it appoints and the costs and fees of the third investment bank, if any, shall be shared equally between the Class C Member and [SpinCo]. 

(iii) The above-described determination of Fair Market Value of the relevant Membership Interests of the Company will be
final and binding on the Members. 
 (d) The Buy-Out Members shall have the option, but not the obligation (the “Buy-Out
Interest Option”), to purchase from the Downgraded Members, and to require each Downgraded Member to sell to the Buy-Out Members, all (but not less than all) of each Downgraded Member’s Membership Interest (the “Buy-Out
Interests”) for a purchase price (the “Buy-Out Purchase Price”) equal to the Fair Market Value of each such Downgraded Member’s Membership Interest (as finally determined pursuant to Section 10.9(c)). The Buy-Out Interest
Option must be exercised with respect to all of the Downgraded Members. The Buy-Out Interest 

  
 42 

 
Option shall be exercisable by the Buy-Out Members, in their sole discretion and at their sole option, by delivering written notice (which written notice shall be irrevocable except as provided
in Section 10.11(a)) to each of the Downgraded Members at any time during the period commencing on the date on which the Fair Market Value of the Membership Interests of the Downgraded Members is finally determined pursuant to
Section 10.9(c) and ending sixty (60) days after such date (the “Buy-Out Interest Option Period”). Such written notice shall obligate each Downgraded Member to sell and the Buy-Out Members to purchase the Buy-Out Interests as
herein provided. The failure of the Buy-Out Members to deliver the written notice during a given Buy-Out Interest Option Period (or the delivery of a written notice by the Buy-Out Members declining to exercise the Buy-Out Interest Option) shall
result in the termination of the Buy-Out Interest Option with respect to such Buy-Out Interest Option Period, and any subsequent exercise of the Buy-Out Interest Option by the Buy-Out Members after such termination shall require the delivery of a
new Valuation Notice to the Downgraded Members with respect to a different Credit Rating Event in accordance with Section 10.9(b). 
 (e) Notwithstanding anything to the contrary herein, no Member shall be entitled to deliver a Valuation Notice or exercise a Buy-Out Interest Option if (i) a Credit Rating Event has occurred with
respect to (A) such Member, (B) any Member of the same class as such Member, (C) the Ultimate Parent of such Member or (D) the Ultimate Parent of any Member of the same class as such Member and (ii) no Cure Event has
occurred with respect to such Credit Rating Event. 
 (f) The Buy-Out Members shall be entitled, in the Buy-Out Members’
sole discretion, to assign all or a portion of its rights and obligations to the Buy-Out Interest Option to any of their Affiliates and to any third party. Such assignment may be made by the Buy-Out Members at any time prior to the consummation of
the Transfer of the Buy-Out Interests hereunder. 
 10.10 BUY-OUT OPTION UPON CHANGE OF CONTROL. 

(a) If there is a Change of Control of [SpinCo], within ten (10) days of such Change of Control [SpinCo] shall deliver a written
notice (a “Change of Control Notice”) to the Class C Member. Notwithstanding anything to the contrary in this Agreement, if there occurs a Change of Control of [SpinCo], the Class C Member may, by delivering written notice to [SpinCo] at
any time after the occurrence of the Change of Control of [SpinCo] but no later than fifteen (15) days after receipt of the Change of Control Notice, require that the Members determine the Fair Market Value of the aggregate Membership Interests
of the Class P Members in accordance with Section 10.9(c) above. 
 (b) If the Class C Member delivers its written notice
in accordance with Section 10.10(a), the Class C Member shall have the option, but not the obligation (the “Change of Control Option”), to purchase such aggregate Membership Interests, and to require the sale of such aggregate
Membership Interests by the Class P Members (the “Change of Control Interests”), for a purchase price (the “Change of Control Purchase Price”) equal to the Fair Market Value of the Change of Control Interests (as finally
determined pursuant to Section 10.9(c)). 

  
 43 

 
The Change of Control Option must be exercised with respect to all of the Class P Members. The Change of Control Option shall be exercisable by the Class C Member, in its sole discretion and at
its sole option, by delivering written notice (which written notice shall be irrevocable except as provided in Section 10.11(a)) to each of the Class P Members at any time during the period commencing on the date on which the Fair Market Value
of the Membership Interests of the Class P Members is finally determined pursuant to Section 10.9(c) and ending sixty (60) days after such date (the “Change of Control Option Period”). Such written notice shall obligate each
Class P Member to sell and the Class C Member to purchase the Change of Control Interests as herein provided. The failure of the Class C Member to deliver the written notice during a given Change of Control Option Period (or the delivery of a
written notice by the Class C Member declining to exercise the Change of Control Option) shall result in the termination of the Change of Control Option with respect to such Change of Control Option Period. 

(c) The Class C Member shall be entitled, in the Class C Member’s sole discretion, to assign all or a portion of its right and
obligations to the Change of Control Option to any of its Affiliates and to any third party. Such assignment may be made by the Class C Member at any time prior to the consummation of the Transfer of the Change of Control Interests hereunder.

 10.11 CLOSING OF BUY-OUT OPTION EXERCISES. 
 (a) The closing of the sale and purchase of Membership Interests pursuant to the Change of Control Option or pursuant to the Buy-Out Interest Option shall take place at the offices of the Purchaser’s
counsel ninety (90) days after, as applicable, (i) the date of the exercise of the Buy-Out Interest Option or (ii) the date of the exercise of the Change of Control Option; provided, that the closing shall in no event occur earlier
than five (5) days after receipt of all approvals required from, and expiration of all waiting periods (including waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended) imposed by, any governmental
authorities in connection with the purchase and sale. At closing, (w) each Member selling its Membership Interest (the “Seller Member”) shall represent and warrant to each Member (or its assignee(s)) purchasing such Membership
Interest (the “Purchaser”) that the Purchaser is receiving good and marketable legal and beneficial title to such Seller Member’s Membership Interest, free and clear of any liens (other than restrictions imposed by the Securities Act
of 1933, as amended, applicable state securities laws, and this Agreement), which representations and warranties shall be the sole representations and warranties required of such Seller Member, (x) the Purchaser shall assume, and cause the
release of each Seller Member from, each on-going obligation of such Seller Member under this Agreement and in respect of the Company and its business, including all obligations under guarantees issued by such Seller Member, in each case arising
after the closing of the sale and purchase of such Membership Interest, (y) each Seller Member shall deliver resignations from those Voting Directors the Seller Member has elected to the Board of Directors, and (z) the Purchaser shall
deliver to each of the Seller Member(s) an amount equal to either the applicable Buy-Out Purchase Price (in the case of the purchase of the Membership Interest pursuant to the Buy-Out Interest Option) or the applicable Change of Control Purchase
Price (in the case of the purchase of the Membership Interest pursuant to the Change of Control Option) in immediately available funds; provided that 

  
 44 

 
nothing in the foregoing clause (x) shall relieve any Seller Member of any of its obligations pursuant to the Contribution Agreement. Notwithstanding anything to the contrary in this
Section 10.11, if a governmental authority whose approval is required to consummate the purchase of the Membership Interest fails to approve such transaction or imposes a condition on its approval that, in the sole discretion of the Purchaser,
would make the purchase by it of the Membership Interest pursuant to the Buy-Out Interest Option or pursuant to the Change of Control Option impractical or not otherwise in the best interests of the Purchaser, then the Purchaser may terminate the
exercise of the applicable option and the purchase of the Membership Interest by and upon delivery of written notice to the Seller Member and, upon such termination, no Member shall have any further obligation under this Section 10.11 with
respect thereto and each such Seller Member shall continue to own its Membership Interest. 
 (b) The Members shall take all
necessary actions required to give effect to the provisions of Section 10.9, Section 10.10 and Section 10.11, including (i) the passing of such Member and Board of Directors resolutions of the Company as may be reasonably
necessary to facilitate the relevant transaction, and (ii) the filing of all necessary notices to and requests for consent of any governmental authorities, and the Members shall equally share any filing fees required in connection therewith.

 (c) If requested in writing by the Purchaser, the Company and the Members hereby agree to cooperate with Purchaser to
structure, in a manner reasonably requested by Purchaser (with the Purchaser to bear the incremental cost, if any, of such request), the Transfer pursuant to the exercise of the Buy-Out Interest Option or the Change of Control Option so as not to
effect a termination of the Company under section 708 of the Code. 
 ARTICLE 11 

COMPETITION 
 11.1 GENERAL. The Members expect that the Company shall be the primary vehicle by which each of the Members (together with their Affiliates) engage in the Chemicals Business. If a majority in
interest of the Members of one class (the “Non-Competing Class”) concludes in good faith that the Company is no longer the primary vehicle by which the Members of the other class (together with its Affiliates) (the “Competing
Class”) is engaged in the Chemicals Business, then the Non-Competing Class shall have the right to send written notice of such good faith conclusion (“Conflict Notice”) to the Competing Class. Upon receipt of the Conflict Notice, the
Competing Class shall enter into good faith negotiations with the Non-Competing Class to resolve any or all substantial conflicts of interest resulting from the ownership of businesses competing with the businesses of the Company. 

  
 45 

 11.2 RESOLUTION OF COMPETITIVE CONFLICTS. 

(a) In the event that: 
 (i) A Non-Competing Class exercises its right to require a Competing Class to engage in good faith negotiations pursuant to Section 11.1; 

(ii) The Non-Competing Class and Competing Class are unable to resolve the conflicts of interest within 150 days of the
delivery of the Conflict Notice; and 
 (iii) The value (in the opinion of a nationally recognized investment
bank selected by the Board of Directors) of the Competing Class’s (including its Affiliates’) interests in businesses competing with the businesses of the Company exceeds 50% of the enterprise value of the Company; provided that if the
Board of Directors does not select such a nationally recognized investment bank within 30 days of the end of the 150 day period set forth in (ii) above, such value shall be determined by nationally recognized investment banks selected by the
process set forth in Section 10.9(c)(ii), mutatis mutandis (including, if necessary, the appointment of a third investment bank to determine such value, if necessary, and without regard to the sentence beginning “Each investment
bank...”); 
 then, in such case, the Non-Competing Class shall have the right, within 30 days from the later of (x) the expiration
of the period in (ii) above or (y) the determination in (iii) above, to state a single cash price at which it is prepared to purchase the Class Membership Interest of the Competing Class, which will constitute a binding offer to
purchase (the “Initial Offer”). In the event of an Initial Offer, the Competing Class shall have 60 days to decide either to accept the Initial Offer or to make a counter-offer by stating a single cash price, which is at least 5% higher
than the Initial Offer, at which it is prepared to purchase the Class Membership Interest of the Non-Competing Class (a “Counter-Offer”). In the event of a Counter-Offer, the Non-Competing Class shall have 30 days to decide either to
accept the Counter-Offer or to make another offer by stating a single cash price, which is at least 5% higher than the Counter-Offer, at which it is prepared to purchase the Class Membership Interest of the Competing Class (a “Subsequent
Offer”). In the event of a Subsequent Offer by the Non-Competing Class, the Competing Class shall have 30 days to decide either to accept the Subsequent Offer or to make another counter- offer by stating a single cash price, which is at least
5% higher than the Subsequent Offer, at which it is prepared to purchase the Class Membership Interest of the Non-Competing Class. The offering process described in this paragraph shall continue in this manner until a price is reached at which
either the Competing Class or the Non-Competing Class is willing to sell its Class Membership Interest to the other class. If such a price is reached, the closing of the sale and purchase of the Membership Interests pursuant to this Article 11 shall
be conducted in accordance with the terms of Sections 10.11(a), (b) and (c), mutatis mutandis. Notwithstanding anything to the contrary in the foregoing, a Member may also sell its Class Membership Interest pursuant to the right of first
refusal provisions set forth in Section 10.6. 

  
 46 

 (b) In the event that a Non-Competing Class has concluded in good faith that the Company is
no longer the primary vehicle by which a Competing Class is engaged in the Chemicals Business in accordance with Section 11.1, and: 
 (i) a sale pursuant to subsection (a) above is not concluded (whether or not the condition expressed in subsection (a)(iii) above is satisfied); and 

(ii) the Competing Class and Non-Competing Class have not been able to resolve, pursuant to Section 11.1 above, all
substantial conflicts of interest resulting from the ownership by the Competing Class of a substantial business competing with the businesses of the Company; 
 then either the Competing Class or the Non-Competing Class may require the other class from time to time to enter into good faith negotiations to cause the Company (and/or the Members) to adopt such
reasonable, mutually acceptable provisions as would mitigate the potential adverse consequences of the conflicts of interests on the continuing businesses of the Company. Such provisions could include, for example, restrictions on the dissemination
and use of confidential information, greater delegation of authority to management of the Company, or modification of distribution requirements or the non-involvement of the Competing Class in business decisions of the Company potentially affecting
such competing businesses. 
 ARTICLE 12 
 TERM AND DISSOLUTION 
 12.1 TERM. Except as provided in

necessary to perform existing obligations, and shall wind up its affairs and liquidate its assets. The Board of Directors, or if there be no Directors then in office the Members, shall appoint a liquidator (who may, but need not, be a Member) who
shall have sole authority and 

  
 47 

 
control over the winding up and liquidation of the Company’s business and affairs and shall diligently pursue the winding up and liquidation of the Company. As soon as practicable after his

12.4 LIABILITIES. Liquidation shall continue until the Company’s affairs are in such condition that there can be a final
accounting, showing that all fixed or liquidated obligations and liabilities of the Company are satisfied or can be adequately provided for under this Agreement. The assumption or guarantee in good faith by one or more financially responsible
persons shall be deemed to be an adequate means of providing for such obligations and liabilities. When the liquidator has determined that there can be a final accounting, the liquidator shall establish a date (not to be later than the end of the
taxable year of the liquidation, i.e., the time at which the Company ceases to be a going concern as provided in section 1.704-1(b)(2)(ii)(g) of the Income Tax Regulations, or, if later, ninety (90) days after the date of such liquidation) for
the distribution of the proceeds of liquidation of the Company (the “Distribution Date”). The net proceeds of liquidation of the Company shall be distributed to the Members as provided in Section 12.6 hereof not later than the
Distribution Date. 
 12.5 SETTLING OF ACCOUNTS. Subject to section 18-804 of the Act, upon the dissolution and
liquidation of the Company, the proceeds of liquidation shall be applied as follows: (a) first, to pay all expenses of liquidation and winding up; (b) second, to pay all debts, obligations and liabilities of the Company, in the order of
priority as provided by law, other than debts owing to the Members or on account of Members’ contributions; (c) third, to pay all debts of the Company owing to a Member; and (d) to establish reasonable reserves for any remaining
contingent or unforeseen liabilities of the Company not otherwise provided for, which reserves shall be maintained by the liquidator on behalf of the Company in a regular interest-bearing trust account for a reasonable period of time as determined
by the liquidator. If any excess funds remain in such reserves at the end of such reasonable time, then such remaining funds shall be distributed by the Company to the Members pursuant to Section 12.6 hereof. 

12.6 DISTRIBUTION OF PROCEEDS. 
 (a) Subject to section 18-804 of the Act, upon final liquidation of the Company but not later than the Distribution Date, the net proceeds of liquidation remaining following the settling of accounts in

 48 

 (b) The balance of Members’ Capital Accounts immediately prior to distributions under
Section 12.6(a) shall be determined after all adjustments to such Capital Accounts for the taxable year of the Company during which the liquidation occurs as are required by this Agreement and Income Tax Regulations section 1.704-1(b), such
adjustments to be made within the time specified in such Income Tax Regulations. 
 12.7 CERTIFICATE OF CANCELLATION.
Upon dissolution and liquidation of the Company, the liquidator shall cause to be executed and filed with the Secretary of State of the State of Delaware, a certificate of cancellation in accordance with section 18-203 of the Act. 

ARTICLE 13 

INDEMNIFICATION 
 13.1 INDEMNIFICATION: PROCEEDING OTHER THAN BY COMPANY. The Company shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or investigative, except an action by or in the right of the Company, by reason of the fact that he is or was a Director, Member or officer of the Company (and may similarly
indemnify employees or agents of the Company), or is or was serving at the request of the Company as a manager, member, director, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or
other enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he acted in good faith and in a manner
which he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Company, and that, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful. 

13.2 INDEMNIFICATION: PROCEEDING BY COMPANY. 
 (a) The Company shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Company to procure a
judgment in its favor by reason of the fact that he is or was an officer of the Company (and may similarly indemnify employees or agents of the Company), or is or was serving at the request of the Company as a manager, member, director, officer,
employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by him in
connection with the defense or settlement of the action or suit if he acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company. 

  
 49 

 (b) The Company will indemnify any person who was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the right of the Company to procure a judgment in its favor by reason of the fact that he is or was a Director of the Company, or is or was a Director of the Company serving at
the request of the Company as a manager, member, director, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and
attorneys’ fees actually and reasonably incurred by him in connection with the defense or settlement of the action or suit if he acted in good faith in accordance with Section 4.8 hereof. 

(c) With respect to indemnification pursuant to subsection (a) or (b) above, such indemnification may not be made for any
claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the Company or for amounts paid in settlement to the Company, unless and only to the
extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such
expenses as the court deems proper. 
 13.3 MANDATORY ADVANCEMENT OF EXPENSES. The expenses of Directors, Members and
officers incurred in defending a civil or criminal action, suit or proceeding must be paid by the Company as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf
of the Director, Member or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by the Company. The provisions of this Section 13.3 do not affect any rights to
advancement of expenses to which personnel of the Company other than Directors, Members or officers may be entitled under any contract or otherwise. 
 13.4 EFFECT AND CONTINUATION. The indemnification and advancement of expenses authorized in or ordered by a court pursuant to Section 13.1 to Section 13.3, inclusive: 

(a) Does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under the
Certificate or any limited liability company agreement, vote of Members or disinterested Directors, if any, or otherwise, for either an action in his official capacity or an action in another capacity while holding his office, except that
indemnification, unless ordered by a court pursuant to Section 13.2 or for the advancement of expenses made pursuant to Section 13.3, may not be made to or on behalf of any Member, Director or officer if a final adjudication establishes
that his acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and was material to the cause of action. 
 (b) Continues for a person who has ceased to be a Member, Director, officer, employee or agent and inures to the benefit of his heirs, executors and administrators. 

  
 50 

 13.5 INSURANCE AND OTHER FINANCIAL ARRANGEMENTS. 

(a) The Board of Directors may cause the Company to purchase and maintain insurance or make other financial arrangements on behalf of any
person who is or was a Member, Director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a manager, Member, director, officer, employee or agent of another limited liability company, corporation,
partnership, joint venture, trust or other enterprise for any liability asserted against him and liability and expenses incurred by him in his capacity as a Director, member, director, officer, employee or agent, or arising out of his status as
such, whether or not the Company has the authority to indemnify him against such liability and expenses.

 (i) The creation of a
trust fund;

(iii) The securing of its obligation of indemnification by granting a security interest or other lien on any assets of the
Company; or 
 (iv) The establishment of a letter of credit, guaranty or surety. 

No financial arrangement made pursuant to this Section 13.5(b) may provide protection for a person adjudged by a court of competent
jurisdiction, after exhaustion of all appeals therefrom, to be liable for intentional misconduct, fraud or a knowing violation of law, except with respect to the advancement of expenses or indemnification ordered by a court. 

(c) In the absence of fraud: 
 (i) The decision of the Company as to the propriety of the terms and conditions of any insurance or other financial arrangement made pursuant to this Section 13.5 and the choice of the person to
provide the insurance or other financial arrangement is conclusive; and 
 (ii) The insurance or other financial
arrangement: 
 (A) Is not void or voidable; and 

  
 51 

 (B) Does not subject any Director or Member approving it to personal
liability for his action, even if a Director or Member approving the insurance or other financial arrangement is a beneficiary of the insurance or other financial arrangement. 
 13.6 NOTICE OF INDEMNIFICATION AND ADVANCEMENT. Any indemnification of, or advancement of expenses to, a Director, Member or officer in accordance with this Article 13, if arising out of a
proceeding by or on behalf of the Company, shall be reported in writing to the Members with or before the notice of the next Members’ meeting. 
 13.7 REPEAL OR MODIFICATION. Any repeal or modification of this Article 13 by the Members of the Company shall not adversely affect any right of a Director, Member or officer of the Company
existing hereunder at the time of such repeal or modification.

reasonably, and solely to the extent relating to matters existing or arising prior to the Spin-off ) at any reasonable time during usual business hours, for a purpose reasonably related to such Person’s interest as a Member. 

  
 52 

 Such inspection may be made in person or by agent or attorney, and the right of inspection includes the
