 SECTION 1 
 ORGANIZATION MATTERS 
  
 1.1 Formation of Partnership; Amended and Restated Agreement. The Certificate of Limited Partnership was filed with the Secretary of State of the State of Delaware on October 17, 1997. The Initial Agreement was

Agreement, the Partnership shall have the power to exercise all the powers and privileges granted by this Agreement and by the Act, together with any powers incidental thereto, so far as such powers and privileges are necessary, appropriate,
convenient or incidental for the conduct, promotion or attainment of the purposes of the Partnership.

other name or names deemed advisable by the Partnership Governance Committee. The General Partners will comply or cause the Partnership to comply with all applicable laws and other requirements relating to fictitious or assumed names.

 1.5 Filings. The Managing General Partner shall, or shall cause the Partnership to, execute, swear
to, acknowledge, deliver, file or record in public offices and publish all such certificates, notices, statements or other instruments, and take all such other actions, as may be required by law for the formation, reformation, qualification,
registration, operation or continuation of the Partnership in any jurisdiction, to maintain the limited liability of the Limited Partners, to preserve the Partnership’s status as a partnership for tax purposes or otherwise to comply with
applicable law. Upon request of the Managing General Partner, the other Partners shall execute all such certificates and other documents as may be necessary, in the sole judgment of the Managing General Partner, in order for the Managing General
Partner to accomplish all such executions, swearings, acknowledgments, deliveries, filings, recordings in public offices, publishings and other acts. Each General Partner hereby agrees and covenants that it will execute any appropriate amendment to
the Certificate of Limited Partnership of the Partnership pursuant to Section 17-204 of the Act to reflect any admission of a Substitute General Partner in accordance with this Agreement. 
  
 1.6 Power of Attorney. Each Partner other than the Managing General Partner hereby irrevocably makes, constitutes and
appoints the Managing General Partner and any successor thereto permitted as provided herein, with full power of substitution and resubstitution, as the true and lawful agent and attorney-in-fact of such Partner, with full power and authority in the
name, place and stead of such Partner to execute, swear, acknowledge, deliver, file or record in public offices and publish: (i) all certificates and other instruments (including counterparts thereof) which the Managing General Partner deems
appropriate to reflect any amendment, change or modification of or supplement to this Agreement in accordance with the terms of this Agreement; (ii) all certificates and other instruments and all amendments thereto which the Managing General Partner
deems appropriate or necessary to form, qualify or continue the Partnership in any jurisdiction, to maintain the limited liability of the Limited Partners, to preserve the Partnership’s status as a partnership for tax purposes or otherwise to
comply with applicable law; and (iii) all conveyances and other instruments or documents which the Managing General Partner deems appropriate or necessary to reflect the transfers or assignments of interests in, to or under, this Agreement,
including the Units, the dissolution, liquidation and termination of the Partnership, and the distribution of assets of the Partnership in connection therewith, pursuant to the terms of this Agreement. 
  
 Each Partner other than the Managing General Partner hereby agrees to execute
and deliver to the Managing General Partner within five Business Days after receipt of a written request therefor such other further statements of interest and holdings, designations, powers of attorney and other instruments as the Managing General
Partner deems necessary. The power of attorney granted herein is hereby declared irrevocable and a power coupled with an interest, shall survive the bankruptcy, dissolution or termination of such Partner and shall extend to and be binding upon such
Partner’s successors and permitted assigns. Each such Partner hereby (i) agrees to be bound by any representations made by the agent and attorney-in-fact acting in good faith pursuant to such power of attorney; and (ii) waives any and all
defenses which may be available to contest, negate, or disaffirm any action of the agent and attorney-in-fact taken in accordance with such power of attorney.

Partnership was filed with the office of the Secretary of State of the State of Delaware through the dissolution of the Partnership in accordance with the provisions of Section 12.

 SECTION 2

	 Partner

	  	Units

	 Lyondell LP4
	  	*821
	 Millennium GP
	  	590
	 Lyondell LP
	  	21,617
	 Millennium LP
	  	28,910
	 Lyondell (Pelican) LP1
	  	6,623
	 Lyondell (Pelican) LP2
	  	**11,439
	 Lyondell LP3
	  	***30,000
	 	  	

	 TOTAL
	  	100,000

	*	This number includes the Unit previously held by Occidental GP and originally held by PDG GP. 

	**	This number includes the 294 Units originally held by PDG GP. 

	***	This number includes 11,437 Units transferred from Lyondell (Pelican) LP2 and 18,563 Units transferred from Lyondell LP. 

  
 The Units shall entitle the holder to the distributions set forth in Section 3 and to
the allocation of Profits, Losses and other items as set forth in Section 4. Units shall not be represented by certificates. 
  
 2.2 Transaction Costs. If the Partnership is entitled to deductions with respect to costs described in either Section 6.10 of the Initial
Master Transaction Agreement or Section 6.10 of the Second Master Transaction Agreement to which a Partner is not entitled to reimbursement, the incurrence of such costs shall not increase the Capital Account of such a Partner, and such
Partner shall be entitled to any deductions attributable to such costs. 
  
 2.3 Property Contributions. 
  
 (a) Pursuant to
its Contribution Agreement, on October 10, 1997, Lyondell LP contributed or caused to be contributed to the Partnership, the Initial Assets contemplated thereby subject to the Assumed Liabilities contemplated thereby. 
  

 5 

 (b) Pursuant to its Contribution Agreement, on October 10, 1997, Millennium LP contributed or caused to
be contributed to the Partnership, the Initial Assets contemplated thereby subject to the Assumed Liabilities contemplated thereby. 
  
 (c) Pursuant to their Contribution Agreement, on May 15, 1998, Occidental LP1, Occidental LP2 and PDG GP contributed or caused to be contributed to the
Partnership, the Initial Assets contemplated thereby subject to the Assumed Liabilities contemplated thereby (which involved, in the case of Occidental LP2, the merger of Oxy Petrochemicals and the Partnership, with the Partnership as the surviving
entity). 
  
 (d) The Partners intend that the contribution of
assets subject to liabilities heretofore made by the Partners to the Partnership pursuant to Sections 2.3(a) through (c) has qualified as a tax-free contribution under Section 721 of the Code in which no Partner has recognized or will
recognize gain or loss. The Partners agree that the Partnership has so filed its tax return, and each Partner agrees to file its tax return on the same basis and to maintain such position consistently at all times thereafter. 
  
 (e) Immediately after the contributions by PDG GP, Occidental LP1, and
Occidental LP2, the Capital Accounts of the Initial Partners were adjusted so that each Partner’s Capital Account would be the same per Unit as that of every other Partner on May 15, 1998 if on such date the special capital distributions
provided in Sections 3.1(e), (f), and (g) of the Amended and Restated Limited Partnership Agreement of Equistar Chemicals, LP dated May 15, 1998 had been made. Schedule 2.3(e) sets forth the Capital Accounts of the Partners as if the
contributions and distributions were made, as has since occurred. 
  
 2.4 Other Contributions. From time to time and subject to the limitations of Section 6.7, if applicable, the Partnership Governance Committee (or the CEO acting pursuant to Section 8.3), on behalf of the Partnership,
may issue a written notice (“Funding Notice”) to the Partners calling for an additional capital contribution to the Partnership. Any Funding Notice will set forth: 
  
 (a) the use of funds therefor; 
  
 (b) the aggregate amount of the capital contribution required, which amount shall be apportioned among the Partners Pro Rata; and 
  
 (c) the date by which the capital contribution must be received by the
Partnership, which date will not be earlier than seven Business Days from the date the Funding Notice is issued. 
  
 Each Partner shall timely wire transfer its Pro Rata share of the amount set forth in the Funding Notice to the Partnership’s bank account. Except as expressly set
forth in this Agreement, no Partner shall be permitted or required to make any additional capital contribution to the Partnership. 
  
 2.5 Capital Accounts. Each Partner’s Capital Account shall be determined and maintained in accordance with Regulation §1.704-1(b)(2)(iv)
as reasonably interpreted by the Tax Matters Partner. The Tax Matters Partner shall have the discretion, after consultation with 
  

 6 

 the Managing General Partner, to make those determinations, valuations, adjustments and allocations with respect to each
Partner’s Capital Account as it deems appropriate so that the allocations made pursuant to this Agreement will have substantial economic effect as such term is used in Regulation §1.704-1(b). If any Partner transfers all or a portion of
its Units in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of the transferor to the extent such Capital Account relates to the transferred Units. 
  
 2.6 No Return of or on Capital. Except as provided in Section 3
and Section 4, no Partner shall receive any interest or other return on its capital contributions or on the balance in its Capital Account and no return of its capital contributions. 
  
 2.7 Partner Loans. A Partner or its Affiliates may loan funds to the
Partnership on such terms and conditions as may be approved by the Partnership Governance Committee, and, subject to other applicable law, have the same rights and obligations with respect thereto as a Person who is neither a Partner nor an
Affiliate of a Partner. The existence of such a relationship and acting in such a capacity will not result in a Limited Partner being deemed to be participating in the control of the business of the Partnership or otherwise affect the limited
liability of a Partner. If a Partner or any Affiliate thereof is a lender, in exercising its rights as a lender, including making its decision whether to foreclose on property of the Partnership, such lender will have no duty to consider (i) its
status as a Partner or an Affiliate of a Partner, (ii) the interests of the Partnership, or (iii) any duty it may have to any other Partner or the Partnership. 
  

2.8 Administration and Investment of Funds. The administration and investment of Partnership funds shall be in accordance with the procedures

 SECTION 4  
 BOOK AND TAX ALLOCATIONS 
  
 4.1 General Book Allocations. This section controls partnership allocations for book purposes. As used herein,
“book” means the allocations used to determine debits and credits to the Capital Accounts of the Partners and to determine the amounts distributable to the Partners pursuant to Section 3 and Section 12.2(d). It does not refer
to the method in which books are maintained for financial reporting purposes pursuant to Section 5.2. Except as otherwise provided in Section 4.2 and Section 4.3, Profits or Losses for book purposes shall be allocated each year
among the Partners Pro Rata, subject to the following: 
  
 (a) If
the tax basis in Partnership assets is increased as a result of the distribution of $75 million to Millennium LP in May 1998, book deductions equal to the tax deductions resulting from such increase shall be allocated to Millennium LP until such
time as gain or income is allocable under (c) below. 
  
 (b) If
the tax basis in Partnership assets is increased as a result of the distribution of 43% of the proceeds of the Lyondell Note to Millennium LP, book deductions equal to the tax deductions resulting from such increase shall be allocated among the
Initial Partners in the ratio of the Units owned by each prior to May 15, 1998 until gain or income is allocable under (c) below. 
  
 (c) If during any 12 month period the Partnership sells, distributes to Partners, or otherwise disposes of more than 50% in value of the assets it owned
at the beginning of such period, gain or income recognized in the taxable period of such sale, distribution or other disposition or thereafter recognized from the sale, distribution, or other disposition of property or from the operation of other
property shall be allocated to the Partners in the ratio in which the aggregate amount of deductions described in (a) and (b) above were allocated to the Partners until the aggregate amount of such gain and income so allocated equals the aggregate
amount of such deductions. 
  
 (d) [Intentionally Deleted.]

  

 8 

 (e) The initial agreed value of the Lease will be amortized ratably over the term of the Lease, and the
resulting deductions shall be allocated to Lyondell (Pelican) LP1. Any gain recognized on the disposition of the Lease shall be allocated to Lyondell (Pelican) LP1. If, prior to such disposition, the Partnership has made capital improvements to such
assets that have been borne by the Partners Pro Rata, then upon the disposition of the Lease with such improvements, gain shall be deemed to be attributable to such improvements to the extent of the excess of its depreciated value for GAAP purposes
at the time of the disposition over its Book Value at such time, and such gain shall be allocated to the Partners Pro Rata. 
  
 (f) Deductions attributable to the Book Value of the assets of the Partnership as they exist immediately after the contributions described in Section
2.3(a) other than the Lease will be allocated among the Partners other than Lyondell (Pelican) LP1 in the ratio of the Units owned by each, and any gain recognized on the disposition of such contributed assets will be allocated to the Partners
other than Lyondell (Pelican) LP1 in the ratio of the Units owned by each. If, prior to disposition of such asset sale, the Partnership has made capital improvements to such assets that have been borne by the Partners Pro Rata, then upon the
disposition of a contributed asset with such improvements, gain shall be deemed to be attributable to such improvements to the extent of the excess of its depreciated value for GAAP purposes at the time of disposition over its Book Value at such
time, and such gain shall be allocated to the Partners Pro Rata. 
  
 (g) To the extent any contribution is made to the Partnership on behalf of a Partner (the “Beneficiary Partner”) pursuant to an indemnity provided under Section 8.6(b), an amount of Book items of loss, expense or
deduction (other than Book loss, depreciation or amortization with respect to any property contributed by a Partner to the Partnership) shall be allocated to the Beneficiary Partner. 
  
 4.2 Change in Partner’s Units. If during a year Units are transferred or new Units issued, allocations among the
Partners shall be made in accordance with their interests in the Partnership from time to time during such year in accordance with Section 706 of the Code, using the closing-of-the-books method, except that depreciation and other amortization with
respect to each Partnership asset shall be deemed to accrue ratably on a daily basis over the entire period during such year that the asset is owned and in service by the Partnership. 
  
 4.3 Deficit Capital Account and Nonrecourse Debt Rules. The special rules in this Section 4.3 apply in the
following order to take into account the possibility of the Partners’ having deficit Capital Account balances for which they are not economically responsible and the effect of the Partnership’s incurring nonrecourse debt, directly or
indirectly. 
  
 (a) Partnership Minimum Gain Chargeback. If
there is a net decrease in “partnership minimum gain” during any year, determined in accordance with the tiered partnership rules of Regulation §1.704-2(k), each Partner shall be allocated items of income and gain for such year equal
to such Partner’s share of the net decrease in partnership minimum gain within the meaning of Regulation §1.704-2(g)(2), except to the extent not required by Regulation §1.704-2(f). To the extent that this subsection (a) is
inconsistent with Regulation §1.704-2(f) or §1.704-2(k) or incomplete with respect to such regulations, the minimum gain chargeback provided for herein shall be applied and interpreted in accordance with such regulations. 
  

 9 

 (b) Partner Minimum Gain Chargeback. If there is a net decrease in “partner nonrecourse debt
minimum gain” during any year, within the meaning of Regulation § 1.704-2(i)(2), each Partner who has a share of such gain, determined in accordance with Regulation § 1.704-2(i)(5), shall be allocated items of income and gain for such
year (and, if necessary, subsequent years) equal to such Partner’s share of the net decrease in partner nonrecourse debt minimum gain. To the extent that this subsection (b) is inconsistent with Regulation § 1.704-2(i) or 1.704-2(k)
or incomplete with respect to such regulations, the partner nonrecourse debt minimum gain chargeback provided for herein shall be applied and interpreted in accordance with such regulations. 
  
 (c) Deficit Account Chargeback and Qualified Income. If any Partner
has an Adjusted Capital Account Deficit at the end of any year, including an Adjusted Capital Account Deficit for such Partner caused or increased by an adjustment, allocation or distribution described in Regulation §1.704-1(b)(2)(ii)(d)(4),
(5) or (6), such Partner shall be allocated items of income and gain (consisting of a pro rata portion of each item of Partnership income, including gross income and gain) in an amount and manner sufficient to eliminate such Adjusted Capital Account
Deficit as quickly as possible. This subsection (c) is intended to constitute a “qualified income offset” pursuant to Regulation §1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. 
  
 (d) Partner Nonrecourse Deductions. Any partner nonrecourse deductions
for any year or other period shall be allocated to the Partner who bears the economic risk of loss with respect to the partner nonrecourse debt to which such partner nonrecourse deductions are attributable in accordance with Regulation
§1.704-2(i) or §1.704-2(k). 
  
 (e) Curative
Allocations. The Allocations provided by this Section 4.3 may not be consistent with the manner in which the Partners intend to divide Profits, Losses and similar items. Accordingly, Profits, Losses and other items will be reallocated
among the Partners (in the same year and to the extent necessary, in subsequent years) in a manner consistent with Regulation §1.704-1(b) and 1.704-2 so as to prevent such allocations from distorting the manner in which Profits, Losses and
other items are intended to be allocated among the Partners pursuant to Sections 4.1 and 4.2. 
  
 (f) Nonrecourse Debt Sharing. For purposes of this Agreement, nonrecourse deductions, within the meaning of Regulation §1.704-2(b), shall be
deemed to be allocated among the Partners Pro Rata. Solely for purposes of determining a Partner’s proportionate share of the “excess nonrecourse liabilities” of the Partnership within the meaning of Regulation §1.752-3(a)(3),
Partnership Profits are allocated to the Partners Pro Rata. 
  
 4.4 Federal Tax Allocations. 
  
 (a) General
Rule. Except as otherwise provided in the following paragraphs of this Section 4.4, allocations for federal income tax purposes of items of income, gain, loss and deduction, and credits and basis therefor, shall be made in the same manner
as book allocations are made. 
  

 10 

 (b) Elimination of Book/Tax Disparities. Taxable income and tax deductions shall be shared among
the Partners so as to take into account the variation between the Book Value and the adjusted tax basis of each property at the time it is contributed to the Partnership and at each time it is revalued. 
  
 (i) To account for such variation, effective as of the
formation of the Partnership: 
  
 (A) the
depreciation and other deductions attributable to the basis that the contributing Partner had in each property at the time of contribution shall be allocated to such Partner, and 
  
 (B) upon disposition of a contributed property, the excess of its Book Value at such time over its tax basis
at such time shall be allocated to the Partner who contributed the property. 
  
 (ii) If the Book Value of a Partnership property is revalued as of a date subsequent to the date of its acquisition by the Partnership, the portion of its Book Value at the time of its disposition that is attributable
to the increase resulting from such revaluation: 
  
 (A) shall be disregarded in applying Section 4.4(b)(i)(B) to the partner who contributed such property, and 
  
 (B) shall be treated for purposes of this Section 4.4(b) as a separate property that was contributed on the revaluation date by the
persons who were partners immediately prior to the revaluation date. 
  
 (iii) The Partners agree that the foregoing allocations constitute a reasonable method for purposes of Reg. 1.704-3(a)(1) and will be so reported and defended by the Partnership and all Partners unless and until the
Partners otherwise agree or a court otherwise requires. 
  
 (c)
Allocation of Items Among Partners. Each item of income, gain, loss, deduction and credit and all other items governed by Section 702(a) of the Code shall be allocated among the Partners in proportion to the allocation of Profits, Losses and
other items to such Partners hereunder, provided that any gain treated as ordinary income because it is attributable to the recapture of any depreciation or amortization shall be allocated among the Partners in accordance with Prop. Treas.
Reg. §§ 1.1245-1(e)(2) and 1.1250-1(f), or, upon promulgation of final regulations with respect to the matters covered therein, such final regulations. 
  
 (d) Section 754 Election Allocations. Income and deductions of the Partnership that are attributable to the Section
754 election shall be allocated to the Partners entitled thereto. 
  
 4.5 Other Tax Allocations. Items of income, gain, loss, deduction, credit and tax preference for state, local and foreign income tax purposes shall be allocated among the Partners in a manner consistent with the allocation of such
items for federal income tax purposes in accordance with the foregoing provisions of this Section.

 6.1 Managing General Partner and Partnership Governance
Committee. 
  
 (a) Except to the extent set forth in this
Agreement, and subject to Partnership Governance Committee Action to the extent required by this Agreement, the Managing General Partner shall have full, exclusive and complete discretion to manage and control the business, property and affairs of
the Partnership, to make all decisions affecting the business, property and affairs of the Partnership and to take all such actions as it deems necessary, appropriate, convenient or incidental to accomplish the purpose of the Partnership as set
forth in Section 1.4 (as such purpose may be expanded in accordance with Section 6.7(i)). 
  
 (b) The Partnership shall have a committee called the “Partnership Governance Committee”. The Partnership Governance Committee shall act
exclusively by means of Partnership Governance Committee Action. As used in this Agreement, “Partnership Governance Committee Action” means any action which the Partnership Governance Committee is authorized and empowered to take in
accordance with this Agreement and the Act and which is taken by the Partnership Governance Committee either (i) by action taken at a meeting of the Partnership Governance Committee duly called and held in accordance with this Agreement or (ii) by a
formal written consent complying with the requirements of Section 6.5(f). In no event shall the Partnership Governance Committee be authorized to act other than by Partnership Governance Committee Action, and any action or purported action by
the Partnership Governance Committee (including any authorization, consent, approval, waiver, decision or vote) not constituting a Partnership Governance Committee Action shall be null and void and of no force and effect. Each Partnership Governance
Committee Action shall be binding on the Partnership. 
  
 (c) The
Partnership Governance Committee shall adopt policies and procedures, not inconsistent with this Agreement (including Section 6.7) or the Act, governing financial controls and legal compliance, including delegations of authority (and
limitations thereon) to the officers of the Partnership as permitted hereby. Such policies and procedures may be revised or revoked (in a manner consistent with this Agreement and the Act) from time to time as determined by the Partnership
Governance Committee. 
  

 15 

 6.2 Limitations on Authority of General Partners. Except as expressly set forth in this Agreement,
each General Partner agrees that its authority to manage and control the Partnership shall be subject to the provisions hereof regarding the Managing General Partner and Partnership Governance Committee Action. Each General Partner agrees not to
exercise, or purport or attempt to exercise any authority (i) to act for or incur, create or assume any obligation, liability or responsibility on behalf of the Partnership or any other Partner, (ii) to execute any documents on behalf of, or
otherwise bind, or purport or attempt to bind, the Partnership or (iii) to otherwise transact any business in the Partnership’s name, in each case unless any required Partnership Governance Committee Action applicable thereto has been duly
obtained.

Managing General Partner and Officers. Except as expressly set forth in this Agreement, no Person or Persons other than (i) the Managing General Partner, acting in conformity with this Agreement and any applicable Partnership Governance

Committee Action, shall be authorized (a) to exercise the powers of the Partnership, (b) to manage the business, property and affairs of the Partnership or (c) to contract for, or incur on behalf of, the Partnership any debts, liabilities or other
obligations. 
  
 6.4 Composition of Partnership Governance
Committee. 
  
 (a) The Partnership Governance Committee shall
consist of four Representatives. Each Designating Partner shall designate two such Representatives (each a “Representative”). All the Representatives of both Designating Partners shall together constitute the Partnership Governance
Committee. 
  
 (b) Each Designating Partner may designate one or
more individuals (each an “Alternate”) who (i) shall be authorized, in the event a Representative is absent from any meeting of the Partnership Governance Committee (and in the order of succession designated by the Partner so
designating the Alternates), to attend such meeting in the place of, and as substitute for, such Representative and (ii) shall be vested with all the powers to take action on behalf of such Partner which the absent Representative could have
exercised at such meeting. The term “Representative,” when used herein with reference to any Representative who is absent from a meeting of the Partnership Governance Committee, shall mean and refer to any Alternate attending such
meeting in place of such absent Representative. 
  
 (c) Promptly
upon the Effective Time, each Designating Partner shall deliver to the other Partners a written notice (i) designating the two persons to serve as such Partner’s initial Representatives and (ii) designating the person or persons, if any, who
are to serve as initial Alternates and their order of succession. 
  
 (d) Each Designating Partner may, in its sole discretion and by written notice delivered to the other Designating Partner and the Partnership at any time or from time to time, remove or replace one or more of its Representatives or change
one or more of its Alternates. If a Representative or Alternate dies, resigns or becomes disabled or incapacitated, the Designating Partner that designated such Representative or Alternate, as the case may be, shall promptly designate a replacement.
Each Representative and each Alternate shall serve until replaced by the Designating Partner that designated such Representative or Alternate, as the case may be. 
  

 16 

 (e) Copies of all written notices designating Representatives and Alternates shall be delivered to the
Secretary and shall be placed in the Partnership minute books, but the failure to deliver a copy of any such notice to the Secretary shall not affect the validity or effectiveness of such notice or the designation described therein. 
  
 (f) Each Representative, in his capacity as such, shall be the agent of the
Designating Partner that designated such Representative. Accordingly, (i) each Representative, as such, shall act (or refrain from acting) with respect to the business, property and affairs of the Partnership solely in accordance with the wishes of
the Designating Partner that designated such Representative and (ii) no Representative, as such, shall owe (or be deemed to owe) any duty (fiduciary or otherwise) to the Partnership or to any Designating Partner other than the Designating Partner
that designated such Representative; provided, however, that nothing in this Agreement is intended to or shall relieve or discharge any Representative or Designating Partner from liability to the Partnership or the Partners on account
of any fraudulent or intentional misconduct of such Representative. Nothing in this Section 6.4(f) shall limit the duty owed to the Partnership by any person acting in his capacity as an officer of the Partnership (including any such officer
who is also a Representative). 
  
 (g) Representatives shall not
receive from the Partnership any compensation for their service or any reimbursement of expenses for attendance at meetings of the Partnership Governance Committee. 
  
 6.5 Partnership Governance Committee Meetings. 
  
 (a) Regular meetings of the Partnership Governance Committee shall be held at such times and at such places as shall from
time to time be determined in advance and committed to a written schedule by the Partnership Governance Committee. The first regular meeting of the Partnership Governance Committee of each fiscal year shall be deemed to be the “Annual
Meeting.” The Secretary shall deliver by commercial courier service or other hand delivery or transmit by facsimile transmission (with proof of confirmation from the transmitting machine), an agenda for each regular meeting to the
Representatives prior to such meeting. To the extent practical, each agenda for a regular meeting shall specify, to a reasonable degree, the business to be transacted at such meeting. Subject to Section 6.6, at any regular meeting of the
Partnership Governance Committee at which a quorum is present, any and all business of the Partnership may be transacted. 
  
 (b) Special meetings of the Partnership Governance Committee may be called by any Representative by delivering by commercial courier service or other hand
delivery or transmitting by facsimile transmission (with proof of confirmation from the transmitting machine), written notice of a special meeting to each of the other Representatives prior to such meeting. To the extent practical, each notice of a
special meeting shall specify, to a reasonable degree, the business to be transacted at, or the purpose of, such meeting. Notice of any special meeting may be waived before or after the meeting by a written waiver of notice signed by the
Representative entitled to notice. A Representative’s attendance at a special meeting shall 
  

 17 

 constitute a waiver of notice unless the Representative states at the beginning of the meeting his objection to the
transaction of business because the meeting was not lawfully called or convened. Special meetings of the Partnership Governance Committee shall be held at the Partnership’s offices (or at such other place or in such other manner as the
Representatives shall agree) at such time as may be stated in the notice of such meeting. Subject to Section 6.6, at any special meeting of the Partnership Governance Committee at which a quorum is present, any and all business of the
Partnership may be transacted. 
  
 (c) One Representative of each
Designating Partner shall serve as a co-chair of each meeting (regular and special) of the Partnership Governance Committee. Either co-chair may instruct the Secretary to include one or more items on a meeting agenda and neither co-chair nor the
Secretary may delete or exclude an agenda item proposed by either co-chair. 
  
 (d) Following each meeting of the Partnership Governance Committee, the Secretary shall promptly draft and distribute minutes of such meeting to the Representatives for approval at the next meeting, and after such
approval shall retain the minutes in the Partnership minute books. 
  
 (e) Representatives, at their discretion, may participate in or hold regular or special meetings of the Partnership Governance Committee by means of a telephone conference or any comparable device or technology by which all individuals
participating in the meeting may hear each other, and participation in such a meeting shall constitute presence in person at such meeting. 
  
 (f) Any action required or permitted to be taken at a meeting of the Partnership Governance Committee may be taken without a meeting if a consent in
writing, setting forth the action so taken, shall be signed by all the Representatives of each Designating Partner, and such consent shall have the same force and effect as a duly conducted vote of the Partnership Governance Committee. A counterpart
of each such consent to action shall be delivered promptly to each of the Representatives and to the Secretary for placement in the minute books of the Partnership, but the failure to deliver a counterpart of any such consent to action to the
Secretary shall not affect the validity or effectiveness of such consent to action. 
  
 6.6 Partnership Governance Committee Quorum and General Voting Requirement. The presence of at least one Representative (including any duly present Alternate) of each Designating Partner shall constitute a
quorum of the Partnership Governance Committee for the transaction of business and the taking of appropriate Partnership Governance Committee Actions at any meeting. No Partnership Governance Committee Action may be taken at any meeting at which a
quorum is not present. Approval of any matter and the taking of any action at any such meeting shall require the affirmative vote or approval of all Representatives (including any duly present Alternates) of each Designating Partner present at such

 20 

 The Partners hereby acknowledge and confirm that any authorization or approval by the Partnership Governance Committee
pursuant to this Section 6.7 of the execution, delivery and performance of any agreement or contract entered into by the Partnership shall be sufficient to authorize and approve any future performance required by the terms of such agreement
or contract, with no further action being required under this Article VI at the time of any such performance. 
  
 6.8 Control of Interested Partner Issues. Notwithstanding anything to the contrary contained in this Agreement, with respect to any Conflict
Circumstance (other than a Conflict Circumstance described in Section 6.7(xx), which shall be governed by Section 6.7), the Nonconflicted Designating Partner (through its Representatives) shall, subject to Section 6.8(b), have
the sole and exclusive power and right for and on behalf, and at the sole expense, of the Partnership (i) to control all decisions, elections, notifications, actions, exercises or nonexercises and waivers of all rights, privileges and remedies
provided to, or possessed by, the Partnership with respect to a Conflict Circumstance and (ii) in the event of any potential, threatened or asserted claim, dispute or action with respect to a Conflict Circumstance, to retain and direct legal counsel
and to control, assert, enforce, defend, litigate, mediate, arbitrate, settle, compromise or waive any and all such claims, disputes and actions. Accordingly, Partnership Governance Committee Action with respect to a Conflict Circumstance (other
than a Conflict Circumstance described in Section 6.7(xx), which shall be governed by Section 6.7) shall require the approval of two Representatives of the Nonconflicted Designating Partner. Each Designating Partner shall, and shall
cause its Affiliates to, take all such actions, execute all such documents and enter into all such agreements as may be necessary or appropriate to facilitate or further assure the accomplishment of this Section. 
  
 (a) The Nonconflicted Designating Partner, in exercising its control, power
and rights pursuant to this Section, shall act in good faith and in a manner it believes to be in the best interests of the Partnership; provided that it shall never be deemed to be in the best interests of the Partnership not to pay, perform
and observe all of the obligations to be paid, performed or observed by or on the part of the Partnership under the terms of any of the Other Agreements (as defined in the Amended and Restated Parent Agreement). The Nonconflicted Designating Partner
shall act through its Representatives, and the approval of two Representatives acting for the Nonconflicted Designating Partner will be sufficient for the Nonconflicted Designating Partner (and therefore the Partnership Governance Committee on
behalf of the Partnership) to take any action in respect of the relevant Conflict Circumstance. The Conflicted Designating Partner (or its Affiliates) shall have the right to deal with the Partnership and with the Nonconflicted Designating Partner
on an arm’s-length basis and in a manner it believes to be in its own best interests, but in any event must deal with them in good faith. 
  
 6.9 Auxiliary Committees. 
  
 (a) From time to time, the Partnership Governance Committee may, by Partnership Governance Committee Action, designate one or more committees
(“Auxiliary Committees”) or disband any Auxiliary Committee. Each Auxiliary Committee shall (i) operate under the specific authority delegated to it by the Partnership Governance Committee (consistent with Section 6.7) for
the purpose of assisting the Partnership Governance Committee in managing (on behalf of the Designating Partners) the business, property and affairs of the Partnership and (ii) report to the Partnership Governance Committee. 
  

 21 

 (b) Each Designating Partner shall have the right to appoint an equal number of members on each Auxiliary
Committee. Auxiliary Committee members may (but need not) be members of the Partnership Governance Committee. No Auxiliary Committee member shall be compensated or reimbursed by the Partnership for service as a member of such Auxiliary Committee.

  
 (c) Each Partnership Governance Committee Action designating
an Auxiliary Committee shall be in writing and shall set forth (i) the name of such Auxiliary Committee, (ii) the number of members and (iii) in such detail as the Partnership Governance Committee deems appropriate, the purposes, powers and
authorities (consistent with Section 6.7) of such Auxiliary Committee; provided, however, that in no event shall any Auxiliary Committee have any powers or authority in reference to amending this Agreement, adopting an agreement
of merger, consolidation or conversion of the Partnership, authorizing the sale, lease or exchange of all or substantially all of the property and assets of the Partnership, authorizing a dissolution of the Partnership or declaring a distribution.
Each Auxiliary Committee shall keep regular minutes of its meetings and promptly deliver the same to the Partnership Governance Committee. 
  
 6.10 Certain Limitations on Partner Representatives. No Representative or Alternate of a Partner who, as an officer, director or employee of such
Partner or any of its Affiliates, participates in material operational decisions by such Partner or Affiliate regarding a business or operation of such Partner or Affiliate that competes with a business or operation of the Partnership or of the
other Partner or its Affiliates, or that competes with a Business Opportunity offered pursuant to Section 9.3(c) or (d), shall receive or have access to any competitively sensitive information regarding the competing business of the
Partnership or of the other Partner or its Affiliates or such Business Opportunity, nor shall such Representative or Affiliate participate in any decision of the Partnership Governance Committee relating to such business or operation of the
Partnership or the other Partner or its Affiliates or such Business Opportunity. 
  
 6.11 Right of Lyondell LP4 to Become a General Partner. Lyondell LP4 may, at any time after December 31, 2004 at its sole discretion, become a General Partner by (a) giving notice to the other Partners to such
effect, and (b) executing and delivering a counterpart of this Agreement specifying on the signature page that it is signing as a General Partner. At any time upon or after becoming a General Partner, Lyondell LP4 may, at its sole discretion, become
the Managing General Partner (replacing Millennium GP as such) by giving notice to the other Partners to such effect. Upon Lyondell LP4’s becoming a General Partner, the Partnership shall prepare, execute and file (a) an amendment to its
Certificate of Limited Partnership pursuant to the applicable law of the State of Delaware reflecting that Lyondell LP4 is a General Partner and (b) any other filings with governmental or regulatory authorities as may be necessary or appropriate to
reflect the same.

 SECTION 7 
 OFFICERS AND EMPLOYEES 
  
 7.1 Partnership Officers. 
  
 (a) The Partnership
Governance Committee may select natural persons who are (or upon becoming an officer will be) agents or employees of the Partnership to be designated as officers of the Partnership, with such titles as the Partnership Governance Committee shall
determine. 
  
 (b) The executive officers of the Partnership shall
consist of a Chief Executive Officer (“CEO”), and others as determined from time to time by Partnership Governance Committee (collectively, the “Executive Officers”). 
  
 (c) The Partnership Governance Committee also shall appoint a Secretary and
may appoint such other officers and assistant officers and agents as may be deemed necessary or desirable and such persons shall perform such duties in the management of the Partnership as may be provided in this Agreement or as may be determined by
Partnership Governance Committee Action. 
  
 (d) The Partnership
Governance Committee may leave unfilled any offices except those of CEO and Secretary. Two or more offices may be held by the same person except that the same person may not hold the offices of CEO and Secretary. 
  
 7.2 Selection and Term of Executive Officers. 
  
 (a) The Executive Officers as of the date of this Agreement are listed on
Appendix C. 
  
 (b) The CEO shall hold office until December 31,
2010, subject to the CEO’s earlier death, resignation or removal. Upon the expiration of such term or earlier vacancy, the Managing General Partner shall designate the CEO, provided that such person shall be reasonably acceptable to the other
Designating Partner. The CEO shall not be required to be an employee of the Partnership. 
  
 (c) Each Executive Officer (other than the CEO) shall hold office for a five-year term, subject to such Officer’s earlier death, resignation or removal. Upon the death, resignation or removal of an Executive
Officer, or the creation of a new Executive Officer position, the CEO may nominate a person to fill the vacancy, which shall be subject to Partnership Governance Committee approval. Executive Officers shall not be required to be employees of the
Partnership. Any Executive Officer also may serve as an officer or employee of any Partner or Affiliate of a Partner. 
  
 7.3 Removal of Executive Officers. 
  
 (a) The CEO may be removed, at any time, by Partnership Governance Committee Action taken pursuant to Section 6.7(xii), with or without cause,
whenever in the judgment of the Partnership Governance Committee the best interests of the Partnership would be served thereby. 
  
 (b) Any Executive Officer (other than the CEO), or any other officer or agent may be removed, at any time, by Partnership Governance Committee Action
taken pursuant to Section 6.7(xii), with or without cause, whenever in the judgment of the Partnership Governance Committee the best interests of the Partnership would be served thereby. 
  

 23 

 (c) Notwithstanding anything to the contrary in Sections 6.7(xii), 7.3(a) and 7.3(b), either
Designating Partner may, by action of two or more of its Representatives, remove from office any Executive Officer who takes or causes the Partnership to take any action described in Section 6.7 that has not been approved by Partnership
Governance Committee Action as contemplated by Section 6.7. Any such removal shall be effected by delivery by such Representatives of written notice of such removal (i) to such Executive Officer and (ii) to the Representatives of the other
Designating Partner; provided that such removal shall not be effective if such action is rescinded or cured (to the reasonable satisfaction of the Designating Partner who has delivered such notice) promptly after such notice is delivered.

  
 7.4 Duties. 
  
 (a) Each officer or employee of the Partnership shall owe to the
Partnership, but not to any Partner, all such duties (fiduciary or otherwise) as are imposed upon such an officer or employee of a Delaware corporation. Without limitation of the foregoing, each officer and employee in any dealings with a Partner
shall have a duty to act in good faith and to deal fairly; provided, that, no officer shall be liable to the Partnership or to any Partner for his or her good faith reliance on the provisions of this Agreement. Notwithstanding the
foregoing, it is understood that any officer or employee of the Partnership who is also a Representative of a Designating Partner shall, in his capacity as a Representative, owe no duty (fiduciary or otherwise) to any Person other than such
Designating Partner. 
  
 (b) The policies and procedures of the
Partnership adopted by the Partnership Governance Committee may set forth the powers and duties of the officers of the Partnership to the extent not set forth in or inconsistent with this Agreement. The officers of the Partnership shall have such
powers and duties, except as modified by the Partnership Governance Committee, as generally pertain to their respective offices in the case of a publicly held Delaware corporation, as well as other such powers and duties as from time to time may be
conferred by the Partnership Governance Committee and by this Agreement. The CEO and the other officers and employees of the Partnership shall develop and implement management and other policies and procedures consistent with this Agreement and the
general policies and procedures established by the Partnership Governance Committee. 
  
 (c) Notwithstanding any other provision of this Agreement, no Partner, Representative, officer, employee or agent of the Partnership shall have the power or authority, without specific authorization from the
Partnership Governance Committee, to undertake any of the following: 
  
 (i) to do any act which contravenes (or otherwise is inconsistent with) this Agreement or which would make it impracticable or impossible to carry on the Partnership’s business; 
  
 (ii) to confess a judgment against the Partnership;

  
 (iii) to possess Partnership property other
than in the ordinary conduct of the Partnership’s business; or 
  
 (iv) to take, or cause to be taken, any of the actions described in Section 6.7. 
  

 24 

 7.5 CEO. Subject to the terms of this Agreement, the CEO shall have general authority and
discretion comparable to that of a chief executive officer of a publicly held Delaware corporation of similar size to direct and control the business and affairs of the Partnership, including without limitation its day-to-day operations in a manner
consistent with the Annual Budget and the most recently approved Strategic Plan. The CEO shall take steps to implement all orders and resolutions of the Partnership Governance Committee or, as applicable, any Auxiliary Committee. The CEO shall be
authorized to execute and deliver, in the name and on behalf of the Partnership, (i) contracts or other instruments authorized by Partnership Governance Committee Action and (ii) contracts or instruments in the usual and regular course of business
(not otherwise requiring Partnership Governance Committee Action), except in cases when the execution and delivery thereof shall be expressly delegated by the Partnership Governance Committee to some other officer or agent of the Partnership, and,
in general, shall perform all duties incident to the office of CEO as well as such other duties as from time to time may be assigned to him or her by the Partnership Governance Committee or as are prescribed by this Agreement. 
  
 7.6 Other Officers. The President (if any) and the Vice Presidents
shall perform such duties as may, from time to time, be assigned to them by the Partnership Governance Committee or by the CEO. In addition, at the request of the CEO, or in the absence or disability of the CEO, the President (if any) or any Vice
President, in any order determined by the Partnership Governance Committee, temporarily shall perform all (or if limited through the scope of the delegation, some of) the duties of the CEO, and, when so acting, shall have all the powers of, and be
subject to all restrictions upon, the CEO. 
  
 7.7
Secretary. The Secretary shall keep the minutes of all meetings (and copies of written records of action taken without a meeting) of the Partnership Governance Committee in minute books provided for such purpose and shall see that all notices
are duly given in accordance with the provisions of this Agreement. The Secretary shall be the custodian of the records and of the seal, if any. The Secretary shall have general charge of books and papers of the Partnership as the Partnership
Governance Committee may direct and, in general, shall perform all duties and exercise all powers incident to the office of Secretary and such other duties and powers as the Partnership Governance Committee or the CEO from time to time may assign to
or confer upon the Secretary. 
  
 7.8 Salaries. Salaries or
other compensation of the other Executive Officers of the Partnership shall be established by the CEO consistent with plans approved by the Partnership Governance Committee. Except as approved by the Partnership Governance Committee, all fees and
compensation of the officers and employees of the Partnership other than the CEO with respect to their services as such officers and employees shall be payable solely by the Partnership and no Partner or its Affiliates shall pay (or offer to pay)
any such fees or compensation to any officer or employee, except to the extent that the Partnership shall have agreed with a Partner or one of its Affiliates pursuant to a separate agreement that a portion of the compensation of such officer or
employee shall be paid by such Partner or Affiliate. 
  
 7.9
Delegation. The Partnership Governance Committee may delegate temporarily the powers and duties of any officer of the Partnership, in case of absence or for any other reason, to any other officer of the Partnership, and may authorize the
delegation by any officer of the Partnership of any of such officer’s powers and duties to any other officer or employee of the Partnership, subject to the general supervision of such officer. 
  

 25 

 7.10 [Intentionally Deleted.] 
  
 7.11 General Authority. Persons dealing with the Partnership are entitled to rely conclusively on the power and
authority of each of the officers as set forth in this Agreement. In no event shall any Person dealing with any officer with respect to any business or property of the Partnership be obligated to ascertain that the terms of this Agreement have been
complied with, or be obligated to inquire into the necessity or expedience of any act or action of the officer; and every contract, agreement, deed, mortgage, security agreement, promissory note or other instrument or document executed by the
officer with respect to any business or property of the Partnership shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and/or delivery thereof, this Agreement
was in full force and effect, (ii) the instrument or document was duly executed in accordance with the terms and provisions of this Agreement and is binding upon the Partnership, and (iii) the officer was duly authorized and empowered to execute and
deliver any and every such instrument or document for and on behalf of the Partnership. 
  
 SECTION 8 
 STRATEGIC PLANS, ANNUAL BUDGETS AND LOANS 
  
 8.1 Strategic Plan. 
  
 (a) The Partnership shall be managed in accordance with a five-year
strategic business plan (the “Strategic Plan”) which shall be updated annually under the direction of the CEO and presented for approval by the Partnership Governance Committee pursuant to Section 6.7 as soon as practicable
prior to the start of the first fiscal year covered by the updated plan. 
  
 (b) The Strategic Plan shall establish the strategic direction of the Partnership, including plans relating to capital maintenance and enhancement, geographic expansion, acquisitions and dispositions, new product
lines, technology, long-term supply and customer arrangements, internal and external financing, environmental and legal compliance, and plans, programs and policies relating to compensation and industrial relations. The Strategic Plan shall include
projected income statements, balance sheets and cash flow statements, including the expected timing and amounts of capital contributions and cash distributions. The format and level of detail of each Strategic Plan shall be consistent with that of
the initial Strategic Plan agreed to by the Initial Partners on or prior to the Initial Closing Date or the Strategic Plan most recently approved pursuant to Section 6.7. 
  
 8.2 Annual Budget. 
  
 (a) The Executive Officers of the Partnership shall prepare an Annual Budget (each, an “Annual Budget”) for each fiscal year, including
an Operating Budget and Capital Expenditure Budget; provided that each Annual Budget shall be consistent with the information for such fiscal year included in the Strategic Plan most recently approved pursuant to Section 6.7; and
provided, further, that unless provided otherwise in the most recently approved 
  

 26 

 Strategic Plan, the Annual Budget (including any Annual Budget prepared under Section 8.2(b)) shall utilize a
format and provide a level of detail consistent with the Partnership’s initial Annual Budget. The Annual Budget for each year shall be submitted to the Partnership Governance Committee for approval at least 30 days prior to the start of the
fiscal year covered by such budget. Each Annual Budget shall incorporate (i) a projected income statement, balance sheet and a cash flow statement, (ii) the amount of any corresponding cash deficiency or surplus and (iii) the estimated amount, if
any, and expected timing for all required capital contributions. Each proposed Annual Budget shall be prepared on a basis consistent with the Partnership’s financial statements. 
  
 (b) If for any fiscal year the Partnership Governance Committee has failed to approve an updated Strategic Plan, then,
subject to Section 8.5, for such year and each subsequent year prior to approval of an updated Strategic Plan, the Executive Officers of the Partnership shall prepare (and promptly furnish to the Partnership Governance Committee) the Annual
Budget consistent with the projections and other information for that year included in the Strategic Plan most recently approved pursuant to Section 6.7; provided, however, that the CEO, acting in good faith, shall be entitled
to modify any such Annual Budget in order to satisfy current contractual and compliance obligations and to account for other changes in circumstances resulting from the passage of time or the occurrence of events beyond the control of the
Partnership; provided, further, that the CEO shall not be authorized to cause the Partnership to proceed with capital expenditures to accomplish capital enhancement projects except to the extent that such expenditures would enable the
Partnership to continue or complete any such capital project reflected in the last Strategic Plan that was approved by the Partnership Governance Committee pursuant to Section 6.7. 
  
 (c) Each “Operating Budget” shall constitute an estimate for each applicable period of all operating income, which
shall include expenses required to maintain, repair and restore to good and usable condition the Partnership’s assets. 
  
 (d) Each “Capital Expenditure Budget” shall constitute an estimate for the applicable period of the capital expenditures required to (i)
accomplish capital enhancement projects included in the most recently approved Strategic Plan, (ii) maintain and preserve the Partnership’s assets in good operating condition and repair and (iii) achieve or maintain compliance with any HSE Law.

  
 8.3 Funding of Partnership Expenses. All Partnership
expenses (both operating and capital expenses), regardless of whether included in any Strategic Plan or Annual Budget, shall be funded from operating cash flows or authorized borrowings under available lines of credit, unless otherwise agreed by the
Partnership Governance Committee. Subject to the limitations of Section 2.4 and Section 6.7(v), if applicable, to the extent that the CEO determines at any time that funds are needed to fund Partnership operations, the CEO may issue a
Funding Notice to the Limited Partners calling for an additional capital contribution. The Limited Partners will take all steps necessary to cause compliance with such Funding Notice. 
  

 27 

 8.4 Implementation of Budgets and Discretionary Expenditures by CEO. 
  
 (a) After a Strategic Plan and an Annual Budget have been approved by the
Partnership Governance Committee (or an Annual Budget has been developed in accordance with Section 8.2(b)), the CEO will be authorized, without further action by the Partnership Governance Committee, to cause the Partnership to make
expenditures consistent with such Strategic Plan and Annual Budget; provided, however, that all internal control policies and procedures, including those regarding the required authority for certain expenditures, shall have been
followed. 
  
 (b) In any emergency, the CEO or the CEO’s
designee shall be authorized to take such actions and to make such expenditures as may be reasonably necessary to react to the emergency, regardless of whether such expenditures have been included in an approved Strategic Plan or Annual Budget.
Promptly after learning of an emergency, the CEO or such designee shall notify the Representatives of the nature of the emergency and the response that has been made, or is committed or proposed to be made, with respect to the emergency. 

 
 8.5 Strategic Plan Deadlock. If the Partnership Governance
Committee has not agreed upon and approved an updated Strategic Plan, as contemplated by Sections 6.7 and Section 8.1, by such date as is 12 months after the beginning of the first fiscal year that would have been covered by such plan,
then the Designating Partners shall submit their disagreements to non-binding mediation by a Neutral. If the Designating Partners are unable to agree upon a mutually acceptable Neutral within 30 days after a nomination of a Neutral is made by one
Designating Partner to the other, then such Neutral shall upon the application of either Designating Partner be appointed within 70 days of such nomination by the Center for Public Resources, or if such appointment is not so made promptly then
promptly thereafter by the American Arbitration Association in Philadelphia, Pennsylvania, or if such appointment is not so made promptly then promptly thereafter by the senior United States District Court judge sitting in Wilmington, Delaware. The
fees of the Neutral shall be paid equally by the Designating Partners. Within 20 days of selection of the Neutral, two persons having decision-making authority on behalf of each Designating Partner shall meet with the Neutral and agree upon
procedures and a schedule for attempting to resolve the differences between the Designating Partners. They shall continue to meet thereafter on a regular basis until (i) agreement is reached by the Designating Partners (acting through their
Representatives) on an updated Strategic Plan or (ii) at least 24 months have elapsed since the beginning of the first fiscal year that was to be covered by the first updated plan for which agreement was not reached and one Designating Partner shall
determine and notify the other Designating Partner and the Neutral in writing (a “Deadlock Notice”) that no agreement resolving the dispute is likely to be reached. 
  
 8.6 Loans. 
  
 (a) Other Loans. The Partnership Governance Committee may by Partnership Governance Committee Action authorize the CEO to cause the Partnership to
borrow funds from third party lenders. No Partner shall be required, and the Partnership Governance Committee shall not be authorized to require any Partner, to guarantee or to provide other credit or financial support for any loan. Except as
provided in Section 8.6(b) or with respect to obligations of Lyondell existing as of January 1, 2002 with respect to Lyondell Assumed Debt, no Partner may 
  

 28 

 guarantee or provide other credit or financial support for all or any portion of any debt, including any refinancing of
the Bank Credit Agreement or any uncommitted lines of credit of the Partnership. 
  
 (b) Millennium Indemnity. At any time and from time to time, Millennium America (or Millennium Petrochemicals Inc. or any other Affiliate of Millennium America) may, in its sole discretion, elect to execute in
favor of the Partnership and the other Partners an indemnity with respect to any debt of the Partnership substantially in the form of Schedules 8.6(A) and 8.6(B); provided, however, that the conditions for release from such an
indemnity shall be as specified by the indemnitor; and provided, further, that the existence of such indemnity shall not prohibit the Partnership from repaying such indemnified debt at any time subject to the other provisions of this
Agreement. The aggregate amount of the Millennium Indemnity shall not exceed $300 million. The Millennium Indemnity shall be with respect to any indebtedness of the Partnership that Millennium America (or such Affiliate) may elect. The Partnership
and the Partners will cooperate with Millennium America (or such Affiliate) in establishing the Millennium Indemnity, including executing any documents necessary to establish the Millennium Indemnity. 
  
 SECTION 9 
 RIGHTS OF PARTNERS 
  
 9.1 Delegation and Contracts with Related Parties. 
  
 (a) The Partners acknowledge that the Managing General Partner (acting, to the extent required, pursuant to Partnership Governance Committee Action) and the Partnership Governance Committee are permitted to delegate
responsibility for day-to-day operations of the Partnership to officers and employees of the Partnership. 
  
 (b) Upon receipt of any required approval by the Partnership Governance Committee (including, as applicable, any approval required by Section 6.8),
all contracts and transactions between the Partnership and a Partner or its Affiliates shall be deemed to be entered into on an arm’s-length basis and to be subject to ordinary contract and commercial law, without any other duties or rights
being implied by reason of a Partner being a Partner or by reason of any provision of this Agreement or the existence of the Partnership. 
  
 9.2 General Authority. Persons dealing with the Partnership are entitled to rely conclusively on the power and authority of any General Partner as
set forth in this Agreement. In no event shall any Person dealing with a General Partner or such General Partner’s representatives with respect to any business or property of the Partnership be obligated to ascertain that the terms of this
Agreement have been complied with, or be obligated to inquire into the necessity or expedience of any act or action of the General Partner or the General Partner’s representatives; and every contract, agreement, deed, mortgage, security
agreement, promissory note or other instrument or document executed by the General Partner or the General Partner’s representatives with respect to any business or property of the Partnership shall be conclusive evidence in favor of any and
every Person relying thereon or claiming thereunder that (i) at the time of the execution and/or delivery thereof, this Agreement was in full force and effect, (ii) the instrument or document was duly executed in accordance with the terms and

  

 29 

 provisions of this Agreement and is binding upon the Partnership, and (iii) the General Partner or the General
Partner’s representative was duly authorized and empowered to execute and deliver any and every such instrument or document for and on behalf of the Partnership. Nothing in this Section 9.2 shall be deemed to be a waiver or release of
any General Partner’s obligations to the other Partners as set forth elsewhere in this Agreement. 
  
 9.3 Limitation on Fiduciary Duty; Non-Competition; Right of First Opportunity. 
  
 (a) Each Partner (directly or through its Affiliates) is a sophisticated party possessing extensive knowledge of and
experience relating to, and is actively engaged in, significant businesses in addition to its Contributed Businesses, has been represented by legal counsel, is capable of evaluating and has thoroughly considered the merits, risks and consequences of
the provisions of this Section 9.3 and is agreeing to such provision knowingly and advisedly. The liability of each of the General Partners (including any liability of its Affiliates or its and their respective officers, directors, agents and
employees) or of any Limited Partner (including any liability of its Affiliates or its and their respective officers, agents, directors and employees), either to the Partnership or to any other Partner, for any act or omission by such Partner in its
capacity as a partner of the Partnership that is imposed by such Partner’s status as a “general partner” or “limited partner” (as such terms are used in the Act) of a limited partnership is hereby eliminated, waived and
limited to the fullest extent permitted by law; provided, however, that each Designating Partner shall at all times owe to the other Designating Partner a fiduciary duty in observing the requirement described in Section 6.7 that
two or more Representatives of each Designating Partner shall be required to give their approval before the Partnership may undertake any of the actions listed in Section 6.7. Nothing in this subsection shall relieve any Partner from
liability for any breach of this Agreement and any General Partner shall at all times owe to any other General Partner a duty to act in good faith with respect to all matters involving the Partnership. 
  
 (b) Except as set forth in Section 9.3(c), each Partner’s
Affiliates shall be free to engage in or possess an interest in any other business of any type, including any business in direct competition with the Partnership, and to avail itself of any business opportunity available to it without having to
offer the Partnership or any Partner the opportunity to participate in such business. Except as set forth in Section 9.3(c), it is expressly agreed that the legal doctrine of “corporate or business opportunities” sometimes applied
to a Person deemed to be subject to fiduciary or other similar duties so as to prevent such Persons from engaging in or enjoying the benefits of certain additional business opportunities shall not be applied in the case of any investment,
acquisition, business, activity or operation of any Partner’s Affiliates. 
  
 (i) If a Partner’s Affiliate desires to initiate or pursue an opportunity to undertake, engage in, acquire or invest in a Related
Business by investing in or acquiring a Person whose business is a Related Business, acquiring assets of a Related Business, or otherwise engaging in or undertaking a Related Business (a “Business Opportunity”), such Partner or its
Affiliate (such Partner, together with its Affiliates, being called the “Proposing Partner”) shall offer the Partnership the Business Opportunity on the terms set forth in Section 9.3(c)(ii). 
  

 30 

 (ii) When a Proposing Partner offers a Business Opportunity to the Partnership, the
Partnership shall elect to do one of the following within a reasonably prompt period: 
  
 (A) acquire or undertake the Business Opportunity for the benefit of the Partnership as a whole, at the cost, expense and benefit of the
Partnership; provided, however, that, if the Partnership ceases to actively pursue such opportunity for any reason, then the Proposing Partner will be entitled to proceed under clause (B) below; or 
  
 (B) permit the Proposing Partner to acquire or undertake the
Business Opportunity for its own benefit and account without any duty to the Partnership or the other Partners with respect thereto; provided, however, that if the Business Opportunity is in direct competition with the then existing
business of the Partnership (a “Competing Opportunity”), then the Proposing Partner and the Partnership shall, if either so elects, seek to negotiate and implement an arrangement whereby the Partnership would either (i) acquire or
undertake the Competing Opportunity at the sole cost, expense and benefit of the Proposing Partner under a mutually acceptable arrangement whereby the Competing Opportunity is treated as a separate business within the Partnership with the costs,
expenses and benefits related thereto being borne and enjoyed solely by the Proposing Partner, or (ii) enter into a management agreement with the Proposing Partner to manage the Competing Opportunity on behalf of the Proposing Partner on terms and
conditions mutually acceptable to the Proposing Partner and the Partnership. If the Partnership and the Proposing Partner do not reach agreement as to such arrangement, the Proposing Partner may acquire or undertake the Competing Opportunity for its
own benefit and account without any duty to the Partnership or the other Partners with respect thereto. 
  
 (c) Notwithstanding the provisions of Section 9.3(c)(ii), (i) if the Business Opportunity constitutes less than 25% (based on annual revenues for
the most recently completed fiscal year) of an acquisition of or investment in assets, activities, operations or businesses that is not otherwise a Related Business, then a Proposing Partner may acquire or invest in such Business Opportunity without
first offering it to the Partnership; provided, that, after completion of the acquisition or investment thereof, such Proposing Partner must offer the Business Opportunity to the Partnership pursuant to the terms of Section
9.3(c)(ii); and if the Partnership elects option (A) of Section 9.3(c)(ii) with respect thereto, the Business Opportunity shall be acquired by the Partnership at its fair market value as of the date of such acquisition and (ii) if the
Business Opportunity is (A) part of an integrated project, a substantial element of which is the development, exploration, production and/or sale of oil or gas reserves and (B) located in a country other than the United States, Canada or Mexico then
such Partner or its Affiliate may acquire or invest in such Business Opportunity without first offering it to the Partnership; provided, that subject to any requisite consents and approvals from third parties or governmental authorities, the
Partner or its Affiliate will use commercially reasonable efforts to include the Partnership to the maximum extent practicable in such integrated project with respect to the Business Opportunity portion of the project. 
  

 31 

 (d) Notwithstanding the provisions of Section 9.3(c), any direct or indirect expansion by
LYONDELL-CITGO Refining Company Ltd. of its aromatics business shall not be deemed to constitute a Business Opportunity for purposes of Section 9.3(c). 
  

(e) If (i) the Partnership is presented with an opportunity to acquire or undertake a Business Opportunity (other than pursuant to Section
9.3(c)) that it determines not to acquire or undertake and (ii) the Representatives of one Designating Partner, but not the other Designating Partner, desire that the Partnership acquire or undertake such Business Opportunity, then the
Partnership shall permit such Designating Partner and its Affiliates to acquire or undertake such Business Opportunity and Section 9.3(c)(ii)(B) shall be deemed to be applicable thereto to the same extent as if such Designating Partner and
its Affiliates were a Proposing Partner with respect to such Business Opportunity. 
  
 9.4 Limited Partners. 
  
 (a) No Limited Partner shall take part in the management or control of the Partnership’s business, transact any business in the Partnership’s name or have the power to sign documents for or otherwise to bind the Partnership.

  
 (b) Each Limited Partner shall have the rights with respect to
the Partnership’s books and records as set forth in Section 5.3. 
  
 9.5 Partner Covenants. Each Partner covenants and agrees with the Partnership and with the other Partners as follows: 
  
 (i) It shall not exercise, or purport or attempt to exercise, its authority to withdraw, retire, resign, or assert that it has been
expelled from the Partnership; 
  
 (ii) It shall
not do any act that would make it impossible or impracticable to carry on the Partnership’s business; and 
  
 (iii) It shall not act or purport or attempt to act in a manner inconsistent with any act of a Partner acting pursuant to Partnership
Governance Committee Action or in a manner contrary to the agreements of the Partners set forth in this Agreement; 
  
 provided, that, nothing in this Section 9.5 shall be deemed to waive its rights under Sections 10, 11 or 12. 
  
 9.6 Special Purpose Entities. Each Partner covenants and agrees that
(i) its business shall be restricted solely to the holding of its Units and the doing of things necessary or incidental in connection therewith (including, without limitation, the exercise of its rights and powers under this Agreement), and (ii) it
shall not own any assets, incur any liabilities or engage, participate or invest in any business outside the scope of such business; provided, however, that this Section 9.6 shall not be binding upon (a) Millennium
Petrochemicals Inc., a Virginia corporation, or its successors by operation of law to the extent that any Units shall be Transferred to it in accordance with Section 10.6 or (b) at its option, any Wholly Owned Affiliate of any Partner to whom
Units shall be Transferred pursuant to Section 10.6 if, at the date of such Transfer, such Wholly Owned Affiliate shall have a consolidated net worth, as determined in 
  

 32 

 accordance with GAAP, of at least $50 million. Notwithstanding the foregoing provisions of this Section 9.6, this
Section 9.6 shall not prohibit any Partner from incurring debt payable to its Parent or an Affiliate so long such debt is permitted under Section 2.4 of the Parent Agreement. 
  
 SECTION 10 
 TRANSFERS AND PLEDGES 
  
 10.1
Restrictions on Transfer and Prohibition on Pledge. Except pursuant to Section 11 or the procedures described below in this Section, a Partner shall not, in any transaction or series of transactions, directly or indirectly Transfer all
or any part of its Units. A Partner shall not, in any transaction or series of transactions, directly or indirectly Pledge all or any part of its Units or its interest in the Partnership. Neither the term “Transfer” nor the term
“Pledge,” however, shall include an assignment by a Partner of such Partner’s right to receive distributions from the Partnership so long as such assignment does not purport to assign any right of such Partner to participate in or
manage the affairs of the Partnership, to receive any information or accounting of the affairs of the Partnership, or to inspect the books or records of the Partnership or any other right of a Partner pursuant to this Agreement or the Act. Any
attempt by a Partner to Transfer or Pledge all or a portion of its Units in violation of this Agreement shall be void ab initio and shall not be effective to Transfer or Pledge such Units or any portion thereof. Subject to any
applicable restrictions imposed by the Amended and Restated Parent Agreement, nothing in this Agreement shall prevent the Transfer or Pledge by the owner thereof of any capital stock, equity ownership interests or other security of a Partner or any
Affiliate of a Partner. 
  
 10.2 Right of First Option.

  
 (a) Except as set forth in Section 10.6, without the
consent of both of the Designating Partners, no Partner may Transfer less than all of its Units and no Partner may Transfer its Units for consideration other than cash. Any Limited Partner (or Limited Partners, if there are Affiliated Limited
Partners) and its (or their) Affiliated Designating Partner desiring to Transfer all of their Units (together, the “Selling Partners”) shall give written notice (the “Initial Notice”) to the Partnership and the
other Partners (the “Offeree Partners”) stating that the Selling Partners desire to Transfer their Units and stating the cash purchase price and all other terms on which they are willing to sell (the “Offer Terms”).
Delivery of an Initial Notice shall constitute the irrevocable offer of the Selling Partners to sell their Units to the Offeree Partners hereunder. 
  
 (b) The Offeree Partners shall have the option, exercisable by delivering written notice (the “Acceptance Notice”) of such exercise to
the Selling Partners within 45 days of the date of the Initial Notice, to elect to purchase all of the Units of the Selling Partners on the Offer Terms described in the Initial Notice. If all of the Offeree Partners deliver an Acceptance Notice,
then all of the Units shall be transferred to the Offeree Partners on a pro rata basis (based on the ratio of the number of Units owned by each Offeree Partner delivering an Acceptance Notice to the number of Units owned by all Offeree Partners
delivering an Acceptance Notice or on any other basis that shall be mutually agreed upon between the Offeree Partners delivering an Acceptance Notice). If less than all of the Offeree Partners deliver an Acceptance Notice, the Selling Partners shall
give written notice thereof (the “Additional Notice”) to the Offeree Partners electing to purchase, and such Offeree Partners shall have the option, exercisable by 
  

 33 

 delivery of an Acceptance Notice of such exercise to the Selling Partners within 15 days of such Additional Notice, to
purchase all of the Units, including the Units it had not previously elected to purchase; provided, however, that any election by an Offeree Partner not to purchase all such Units shall be deemed a rescission of such Offeree
Partner’s original Acceptance Notice and an election not to purchase any of the Units of the Selling Partners. The Acceptance Notice shall set a date for closing the purchase, such date to be not less than 30 nor more than 90 days after
delivery of the Acceptance Notice; provided that such time period shall be subject to extension as reasonably necessary (up to a maximum of an additional 120 days after such 90 day period) in order to comply with any applicable filing and
waiting period requirements under the Hart-Scott-Rodino Antitrust Improvements Act. The closing shall be held at the Partnership’s offices. The purchase price for the Selling Partners’ Units shall be paid in cash delivered at the closing.
The purchase shall be consummated by appropriate and customary documentation (including the giving of representations and warranties substantially similar to those set forth in Sections 2.1 through 2.3 of the Second Master Transaction Agreement).

  
 (c) If none of the Offeree Partners elect to purchase the
Selling Partners’ Units within 45 days after the receipt of the Initial Notice, the Selling Partners shall have a further 180 days during which they may, subject to Sections 10.2(d) and (e), consummate the sale of their Units to a third
party purchaser at a purchase price and on such other terms that are no more favorable to such purchaser than the Offer Terms. If the sale is not completed within such further 180-day period, the Initial Notice shall be deemed to have expired and a
new notice and offer shall be required before the Selling Partners may make any Transfer of their Units. 
  
 (d) Before the Selling Partners may consummate a Transfer of their Units to a third party in accordance with this Agreement, the Selling Partners shall
demonstrate to the Offeree Partners that the Person willing to serve as the proposed purchaser’s guarantor under the agreement contemplated by Section 10.2(e)(vi) has outstanding indebtedness that is rated investment grade by
Moody’s Investors Service, Inc. and Standard & Poor’s Corporation, or if such Person has no rated indebtedness outstanding, such Person shall provide an opinion from a nationally recognized investment banking firm that such Person
could be reasonably expected to obtain such ratings. 
  
 (e)
Notwithstanding the foregoing provisions of this Section 10.2, a Partner may Transfer its Units (other than pursuant to Section 10.6) only if all of the following occur: 
  
 (i) The Transfer is accomplished in a non-public offering in compliance with, and exempt from, the
registration and qualification requirements of all federal and state securities laws and regulations. 
  
 (ii) The Transfer does not cause a default under any material contract to which the Partnership is a party or by which the Partnership or
any of its properties is bound. 
  
 (iii) The
transferee executes an appropriate agreement to be bound by this Agreement. 
  
 (iv) The transferor and/or transferee bears all reasonable costs incurred by the Partnership in connection with the Transfer. 
  

 34 

 (v) The business and activities of the transferee comply with Section 9.6.

  
 (vi) The guarantor of the transferee
satisfies the criteria set forth in Section 10.2(d) and delivers an agreement to the ultimate parent entity of the Offeree Partners and to the Partnership, substantially in the form of the Amended and Restated Parent Agreement. 
  
 (vii) The proposed transferor is not in default in the
timely performance of any of its material obligations to the Partnership. 
  
 (viii) The provisions of Section 10.3 are satisfied. 
  
 10.3 Inclusion of General or Limited Partner Units. No Limited Partner may Transfer its Units to any Person (other than in accordance with Section 10.6) unless the Units of its General Partner Affiliate,
if any, and its Limited Partner Affiliate or Affiliates (if any) are simultaneously transferred to such Person or a Wholly Owned Affiliate of such Person. No General Partner may transfer its Units to any Person (other than a Wholly Owned Affiliate
of such Partner) unless the Units of its Affiliated Limited Partner (or Limited Partners, if more than one) are simultaneously transferred to such Person or a Wholly Owned Subsidiary of such Person. 
  
 10.4 Rights of Transferee. Upon consummation of a Transfer in
accordance with Section 10.2, the transferee or transferees shall immediately, and without any further action of any Person, become (i) a Substitute Limited Partner if and to the extent Limited Partner Units are transferred and (ii) a
Substitute General Partner, if and to the extent General Partner Units are transferred. 
  
 10.5 Effective Date of Transfer. Each Transfer shall become effective as of the first day of the calendar month following the calendar month during which the Partnership Governance Committee approves such
Transfer and receives a copy of the instrument of assignment and all such certificates and documents of the character described in Section 10.2, which the Partnership Governance Committee may reasonably request. 
  
 10.6 Transfer to Wholly Owned Affiliate. Without the need for the
consent of any Person (subject to the provisions contained in this Section 10.6): 
  
 (a) any Partner may Transfer its Units to any Wholly Owned Affiliate of such Partner (other than the Partner that is its Affiliate), provided the transferee executes an instrument reasonably satisfactory to all of the
other Partners accepting the terms and provisions of this Agreement (except as may be provided in Section 9.6). Upon consummation of a Transfer in accordance with this Section 10.6(a), the transferee shall immediately, and without any
further action of any Person, become (i) a Substitute Limited Partner if and to the extent Limited Partner Units are transferred and (ii) a Substitute General Partner, if and to the extent General Partner Units are transferred; and 
  
 (b) any Limited Partner may, at its option and at any time, (i) Transfer up
to 99% of its Limited Partner Units to its Affiliated General Partner, if any, whereupon such Limited Partner Units shall, without any further action, become General Partner Units or (ii) Transfer all 
  

 35 

 of the Limited Partner Units held by such Limited Partner to its Affiliated Limited Partner. Promptly following any
Transfer of Limited Partner Units in accordance with this Section 10.6(b), each Partner shall take such actions and execute such instruments or documents (including, without limitation, amendments to this Agreement or supplemental agreements
hereto) as may be reasonably necessary to ensure that each Affiliated Partner Group shall, taken as a whole and following such Transfer, maintain all of its rights under this Agreement as in effect immediately prior to such Transfer (including,
without limitation, the portion of Available Net Operating Cash distributable to such Affiliated Partner Group). 
  
 (c) Notwithstanding any of the foregoing provisions of this Section 10.6, provided that such Transfer does not cause a termination of the
Partnership under Section 708(b)(1)(B) of the Code, any Limited Partner may Transfer all of its Limited Partner Units to any Affiliate of such Limited Partner that already holds solely Limited Partner Units, and any General Partner may Transfer all
of its General Partner Units to any Affiliate of such General Partner that already holds solely General Partner Units. 
  
 10.7 Invalid Transfer. No Transfer of Units which is in violation of this Section 10 shall be valid or effective, and the Partnership shall
not recognize the same for the purposes of making any allocation or distribution. 
  
 SECTION 11  
 DEFAULT 
  
 11.1 Default. 
  
 (a) Each of the following events shall constitute a “Default” and
create the rights provided for in this Section 11 in favor of the Partnership and the Non-Defaulting Partners against the Defaulting Partners: 
  
 (i) the failure by a Partner to make any contribution to the Partnership as required pursuant to this Agreement (other than pursuant to
the Contribution Agreement), which failure continues for at least five Business Days from the date that the Partner is notified such contribution is overdue; or 
  
 (ii) the withdrawal, retirement, resignation or dissolution of a Partner (other than in connection with a
Transfer of all of a Partner’s Units in accordance with this Agreement); or the Bankruptcy of a Partner or its Guarantor. 
  
 (b) The day upon which the Default commences or occurs (or if the Default is subject to a cure period and is not timely cured, then the day following the
end of the applicable cure period) shall be the “Default Date.” Without prejudice to a Partner’s (or any of its Affiliates’) rights to seek temporary or preliminary judicial relief, prior to any such Default Date all
rights and obligations of the Partners under this Agreement shall remain in full force and effect. 
  
 11.2 Remedies for Default. Provided that there shall be no duplication of remedies, without prejudice to any right to pursue independently and at
any time, including simultaneously, any other remedy it may have under law, including the right to seek to recover Damages, or 
  

 36 

 equity, the Non-Defaulting Affiliated Partner Group in its sole discretion may elect to pursue the following remedies:

  
 (a) At any time prior to the expiration of 60 days from the
Default Date, the Non-Defaulting Affiliated Partner Group may elect to purchase all, but not less than all, of the Units of the Defaulting Partners as described in Section 11.3; provided, however, that within 10 days after the
determination of the Fair Market Value, the Non-Defaulting Affiliated Partner Group may elect not to proceed with a purchase of the Units of the Defaulting Partners, in which case the Non-Defaulting Affiliated Partner Group shall have an additional
30 days from their determination not to proceed to elect an alternative remedy under Section 11.2(b) below; and 
  
 (b) At any time prior to the expiration of 60 days from the Default Date (or if the Non-Defaulting Affiliated Partner Group initially elected to pursue
its remedy under Section 11.2(a) above, then at any time prior to the 30-day extension period), the Non-Defaulting Affiliated Partner Group may elect to effect a liquidation of the Partnership under Section 11.4 and thereby
cause the Partnership to dissolve under Section 12.1(iv). 
  
 11.3 Purchase of Defaulting Partners’ Units. 
  
 (a) Upon any election pursuant to Section 11.2(a), the purchase price that the Non-Defaulting Partners shall pay, in the aggregate, to the Defaulting Partners for their Units shall be an amount equal to (i) the amount that the
Defaulting Partners would receive in a liquidation (assuming that any sale under Section 12.2 were for an amount equal to the Fair Market Value, without giving effect to any Damages) reduced by (ii) the unrecovered Damages attributable to the
Default by the Defaulting Partners. 
  
 (b) If the Non-Defaulting
Partners have a right to purchase the Units of the Defaulting Partners, they may first seek a determination of Fair Market Value by delivering notice in writing to the Defaulting Partners. The Non-Defaulting Affiliated Partner Group shall have 10
days from the final determination of Fair Market Value to elect to purchase the Defaulting Partner Units by delivering notice of such election in writing, and the purchase shall be consummated prior to the expiration of 60 days from the date such
notice is delivered; provided that, such time period shall be subject to extension as reasonably necessary (up to a maximum of an additional 120 days after such 60 day period) in order to comply with any applicable filing and waiting period
requirements under the Hart-Scott-Rodino Antitrust Improvements Act. 
  
 (c) The purchase price so determined shall be payable in cash at a closing held at the Partnership’s offices. The purchase shall be consummated by appropriate and customary documentation (including the giving of representations and
warranties substantially similar to those set forth in Sections 2.1 through 2.4 of the Second Master Transaction Agreement) as soon as practicable and in any event within the applicable time period specified in subsection (b).

  
 (d) The Non-Defaulting Partners may assign, in whole or in
part, their right to purchase the Units of the Defaulting Partners to one or more third parties without the consent of any Partner hereunder. 
  

 37 

 (e) If Units are transferred in accordance with this Section 11.3, whether to the Non-Defaulting
Partners or a third party (under subsection (d) above), upon the consummation of such Transfer, each such transferee shall immediately, and without any further action on the part of any Person, become (i) a Substitute Limited Partner if and
to the extent that Limited Partner Units were transferred to such Person and (ii) a Substitute General Partner if and to the extent that General Partner Units were transferred to such Person. 
  
 11.4 Liquidation. Upon any election pursuant to Section
11.2(b), the Non-Defaulting Partners shall have the right to elect to dissolve and liquidate the Partnership pursuant to the procedures in Section 12.1(iv) (such procedures constituting a “Liquidation”); provided,
however, that any amount payable to the Defaulting Partners in such Liquidation pursuant to Section 12.2 shall be reduced by, without duplication, any unrecovered Damages incurred by the Non-Defaulting Partners and the Non-Defaulting
Partners’ Percentage Interest of any unrecovered Damages incurred by the Partnership in connection with the Default. The Non-Defaulting Partners shall deliver notice of such election to dissolve and liquidate in writing to the Partnership and
the other Partners. 
  
 11.5 Certain Consequences of
Default. Notwithstanding any other provision of this Agreement, commencing on the Default Date and (i) prior to the Non-Defaulting Partners’ collection of Damages through the exercise of its legal remedies or otherwise, or (ii) while the
Non-Defaulting Partners are pursuing their remedies under Section 11.2(a) or (b), the Representatives of the Defaulting Designating Partner shall not have any voting or decisional rights with respect to matters requiring Partnership
Governance Committee Action, and such matters shall be determined solely by the Representatives of the Non-Defaulting Designating Partner; provided, however, that the foregoing loss of voting and decisional rights shall not occur as a
result of a Default caused solely by the Bankruptcy of a Partner or a Guarantor described in Section 11.1(a)(ii); and provided further, that in the case of a Default under Section 11.1(a)(i) or (ii), the foregoing loss of
voting and decisional rights shall not apply to those voting and decisional rights contained in Sections 6.7(i), (x), (xvi) or (xviii) of this Agreement, which rights shall continue in full force and effect at all times. 
  
 SECTION 12  
 DISSOLUTION, LIQUIDATION AND TERMINATION 
  
 12.1 Dissolution and Termination. As long as there is at least one other General Partner (who is hereby authorized in such event to conduct the
business of the Partnership without dissolution), the withdrawal, retirement, resignation, dissolution or Bankruptcy of a General Partner shall not dissolve the Partnership. In addition, if there is no other General Partner at the time such event
occurs, such event shall not dissolve the Partnership unless and until (x) 90 days have elapsed since such event and (y) Lyondell LP4 has failed to exercise its right under Section 6.11 to become a General Partner; if Lyondell LP4 so exercises such
right, it is hereby authorized to conduct the business of the Partnership without dissolution. Whether or not the Partnership is dissolved as a result of the occurrence of any such event, such event shall be a Default covered by Section 11.
The Partnership shall be dissolved upon the happening of any one of the following events: 
  
 (i) the written determination of both Designating Partners to dissolve the Partnership; 
  

 38 

 (ii) the entry of a judicial decree of dissolution; 
  
 (iii) any other act or event which results in the
dissolution of a limited partnership under the Act (except as provided in the first sentence of this Section 12.1); 
  
 (iv) the election of a Non-Defaulting Affiliated Partner Group to effect a dissolution of the Partnership under Section 11.4; or

  
 (v) after the delivery of a Deadlock Notice
by a Designating Partner pursuant to Section 8.5, the written determination by either Designating Partner to dissolve the Partnership. 
  
 12.2 Procedures Upon Dissolution. 
  
 (a) General. If the Partnership dissolves, it shall commence winding up pursuant to the appropriate provisions of the Act and the procedures set
forth in this Section 12. Notwithstanding the dissolution of the Partnership, prior to the termination of the Partnership, the business of the Partnership and the affairs of the Partners, as such, shall continue to be governed by this
Agreement. 
  
 (b) Control of Winding Up. The winding up of
the Partnership shall be conducted under the direction of the Partnership Governance Committee; provided, however, that if the dissolution is caused by entry of a decree of judicial dissolution, the winding up shall be carried out in
accordance with such decree. 
  
 (c) Manner of Winding Up.
Unless the provisions of Section 12.2(e) apply, the Partnership shall attempt to sell all property and apply the proceeds therefrom in accordance with this Section 12.2(c) and Section 12.2(d) below. Upon dissolution of the
Partnership, the Partnership Governance Committee shall determine the time, manner and terms of any sale or sales of Partnership property pursuant to such winding up, consistent with its duties and having due regard to the activity and condition of
the relevant market and general financial and economic conditions. Except as otherwise agreed by the Partners, no distributions will be made in kind to any Partner without the consent of each Partner. 
  
 (d) Application of Assets. In the case of a dissolution and winding-up
of the Partnership, the Partnership’s assets shall be applied as follows: 
  
 (i) First, to satisfaction of the liabilities of the Partnership owing to creditors (including Partners and Affiliates of Partners who are
creditors), whether by payment or reasonable provision for payment. Any reserves created to make any such provision for payment may be paid over by the Partnership to an independent escrow holder or trustee, to be held in escrow or trust for the
purpose of paying any such contingent, conditional or unmatured liabilities or obligations, and, at the expiration of such period as the Partnership Governance Committee may deem advisable, such reserves shall be distributed to the Partners or their
assigns in the manner set forth in subsection (d)(ii) below. 
  

 39 

 (ii) Second, after all allocations of Profits or Losses and other items pursuant to
Section 4, to the Partners in accordance with the balances in their Capital Accounts. Any Partner that then has a deficit in its Capital Account shall contribute cash in the amount necessary to eliminate such deficit. Such contributions shall
be made within 90 days after the date in which all undistributed assets of the Partnership have been converted to cash. 
  
 (iii) Notwithstanding the foregoing, if any Partner shall be indebted to the Partnership, then until payment in full of the principal of
and accrued but unpaid interest on such indebtedness, regardless of the stated maturity or maturities thereof, the Partnership shall retain such Partner’s distributive share of Partnership property and apply such sums to the liquidation of such
indebtedness and the cost of operation of such Partnership property during the period of such liquidation. 
  
 (e) Division of Assets upon Deadlock. If dissolution occurs pursuant to Section 12.1(v), then the provisions of this Section 12.2(e)
shall, if elected by any Partner, apply in lieu of the provisions of Section 12.2(c), but subject to the provisions of Section 12.2(d)(ii). In such event, the Partnership properties shall be divided and distributed in kind to the
Partners in accordance with the provisions of Appendix E. 
  
 12.3
Termination of the Partnership. Upon the completion of the liquidation of the Partnership and the distribution of all Partnership assets, the Partnership’s affairs shall terminate and the Partnership shall cause to be executed and filed
a Certificate of Cancellation of the Partnership’s Certificate of Limited Partnership pursuant to the Act, as well as any and all other documents required to effectuate the termination of the Partnership. 
  
 12.4 Asset and Liability Statement. Within a reasonable time following
the completion of the winding-up and liquidation of the Partnership’s business, the Partnership Governance Committee shall supply to each of the Partners a statement (which may be unaudited) which shall set forth the assets and the liabilities
of the Partnership as of the date of complete liquidation, and each Partner’s pro rata portion of distributions pursuant to Section 12.2.

Partner shall, and shall cause each of its Affiliates and its and their respective partners, shareholders, directors, officers, employees and agents (collectively, “Related Persons”) to, keep secret, retain in strictest confidence,
and not distribute, disseminate or disclose any and all Confidential Information except to (i) the Partnership and its officers and employees, (ii) any lender to the Partnership or (iii) any Partner or any of their respective Affiliates or other

statements of, or other information relating to the Partnership shall not be deemed to be the disclosure of Confidential Information (x) to the extent that any Partner (or its ultimate parent entity) deems it necessary to disclose such information
in connection with a proposed strategic transaction, (y) to the extent that any Partner (or its ultimate parent entity) deems it necessary, appropriate or customary pursuant to law, regulation or stock exchange rule (in the reasonable good faith
judgment of such parent entity) to disclose such information in or in connection with (i) filings with the SEC or a stock exchange, (ii) press releases disseminated to the financial community, (iii) presentations to lenders, (iv) discussions with
underwriters for the Partnership’s public debt offerings, (v) presentations to ratings agencies or (vi) information disclosed to similar audiences or (z) to the extent that in order to sustain a position taken for tax purposes, any Partner (or
former partner in the Partnership if such disclosure is with respect to periods in which such Person was a partner in the Partnership) deems it necessary and appropriate to disclose such financial statements or other information. All Confidential
Information disclosed in connection with the Partnership or pursuant to this Agreement shall remain the property of the Person whose property it was prior to such disclosure unless such property has been transferred to the Partnership pursuant to a
Contribution Agreement. 
  
 (b) No Confidential Information
regarding the plans or operations of any Partner or any Affiliate thereof received or acquired by or disclosed to any unaffiliated Partner or Affiliate thereof in the course of the conduct of Partnership business, or otherwise as a result of the
existence of the Partnership, may be used by such unaffiliated Partner or Affiliate thereof for any purpose other than for the benefit of the Partnership in conducting the Partnership Business. The Partnership and each Partner shall have the
affirmative obligation to take all necessary steps to prevent the disclosure to any Partner or Affiliate thereof of information regarding the plans or operations of such Partner and its Affiliates in markets and areas unrelated to the business of
the Partnership in which any other Partner and their respective Affiliates compete. 
  
 (c) In the event that any Partner is legally required (by interrogatories, discovery requests for information or documents, subpoena, civil investigative demand or similar process) to disclose any Confidential
Information, it is agreed that such Partner prior to disclosure will provide the Partnership Governance Committee (and, if such Confidential Information concerns another Partner, such Partner) with prompt notice of such request(s) so that the
Partnership Governance Committee (or such other Partner) may seek an appropriate protective order or other appropriate remedy and/or waive the Partner’s compliance with the provisions of this Section. In the event that such protective order or
other remedy is not obtained, or that the Partnership Governance Committee (and, if such Confidential Information concerns another Partner, such Partner) grants a waiver hereunder, the Partner required to furnish Confidential Information may furnish
that portion (and only that portion) of the Confidential Information which, in the opinion of such Partner’s counsel, such Partner is legally compelled to disclose, and such Partner will exercise its commercially reasonable best efforts to
obtain reliable assurance that confidential treatment will be accorded any Confidential Information so furnished. 
  

 41 

 (d) Any Partner may disclose Confidential Information to a third party who requires such Confidential
Information for the purpose of evaluating a possible purchase of such Partner’s Units in accordance with Section 10; provided, however, that such third party shall be informed by such Partner of the confidential nature of
the information and the existence of this Section 13.1 and prior to any disclosure shall execute a written confidentiality agreement with such Partner substantially identical in scope to this Section and providing that such confidentiality
agreement is also made for the benefit of the Partnership and each of the other Partners. 
  
 (e) The Partners and their Affiliates shall consult with each other on an ongoing basis with respect to disclosures regarding the Partnership and its business and affairs permitted under Section 13.1(a)(y).

  
 13.2 Indemnification. 
  
 (a) Indemnification by Partnership. The Partnership agrees, to the
fullest extent permitted by applicable law, to indemnify, defend and hold harmless each Partner, its Affiliates and their respective officers, directors and employees from, against and in respect of any Liability which such Indemnified Person may
sustain, incur or assume as a result of, or relative to, a Third Party Claim arising out of or in connection with the business, property or affairs of the Partnership, except to the extent that it is Finally Determined that such Third Party Claim
arose out of or was related to actions or omissions of the indemnified Partner, its Affiliates or any of their respective officers, directors or employees (acting in their capacities as such) constituting a breach of this Agreement or any Related
Agreement. The Partnership shall periodically reimburse or advance to any Person entitled to indemnity under this subsection (a) its legal and other expenses incurred in connection with defending any claim with respect to such Liability if
such Person shall agree to reimburse promptly the Partnership for such amounts if it is finally determined that such Person was not entitled to indemnity hereunder. Nothing in this Section 13.2(a) is intended to, nor shall it, affect or take
precedence over the indemnity provisions contained in any Related Agreement. 
  
 (b) Partner’s Right of Contribution. Each Partner hereby agrees, to the fullest extent permitted by law, to indemnify, defend and hold harmless the other Partners, their Affiliates and their respective
officers, directors and employees from and against the indemnifying Partner’s Percentage Interest (calculated at the time any such Liability was incurred) of any Liability that such Indemnified Person may sustain, incur or assume as a result of
or relating to any Third Party Claim arising out of or in connection with the business, property or affairs of the Partnership; provided, however, that such indemnified Partner, its Affiliates and their respective officers, directors
and employees shall not be entitled to indemnity under this subsection (b) to the extent that it is Finally Determined that such Third Party Claim arose out of or was related to actions or omissions of the indemnified Partner, its Affiliates
or any of their respective officers, directors or employees (acting in their capacities as such) constituting a breach of this Agreement or any Related Agreement; provided, further, that such indemnified Partner, its Affiliates and
their respective officers, directors and employees shall not be entitled to indemnity under this subsection (b) unless (x) the indemnified Partner shall first make a written demand for indemnification from the Partnership in accordance with
subsection (a) above and subsection (c) below and the Partnership shall fail to satisfy such demand in a manner reasonably satisfactory to 
  

 42 

 the indemnified Partner within 60 days of such notice or (y) the Partnership is insolvent or otherwise unable to satisfy
its obligations. The indemnifying Partner shall periodically reimburse any Person entitled to indemnity under this subsection (b) for its legal and other expenses incurred in connection with defending any claim with respect to such Liability
if such Person shall agree to reimburse promptly the indemnifying Partner for such amounts if it is Finally Determined that such Person was not entitled to indemnity hereunder. 
  
 (c) Procedures. Promptly after receipt by a Person entitled to indemnification under subsection (a) or (b) (an
“Indemnified Party”) of notice of any pending or threatened claim against it (a “Claim”), such Indemnified Party shall give prompt written notice (including copies of all papers served with respect to such claim) to
the party to whom the Indemnified Party is entitled to look for indemnification (the “Indemnifying Party”) of the commencement thereof, which notice shall describe in reasonable detail the nature of the Third Party Claim, an
estimate of the amount of damages attributable to the Third Party Claim to the extent feasible and the basis of the Indemnified Party’s request for indemnification under this Agreement; provided that the failure to so notify the
Indemnifying Party shall not relieve the Indemnifying Party of any liability that it may have to any Indemnified Party except to the extent the Indemnifying Party demonstrates that it is prejudiced thereby. In case any Claim that is subject to
indemnification under subsection (a) shall be brought against an Indemnified Party and it shall give notice to the Indemnifying Party of the commencement thereof, the Indemnifying Party may, and at the request of the Indemnified Party shall,
participate in and control the defense of the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party. The Indemnified Party shall have the right to employ separate counsel in any such action and to participate
in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) the employment thereof has been specifically authorized in writing by the Indemnifying Party, (ii) the Indemnifying Party
failed to assume the defense and employ counsel or failed to diligently prosecute or settle the Third Party Claim or (iii) there shall exist or develop a conflict that would ethically prohibit counsel to the Indemnifying Party from representing the
Indemnified Party. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest, including, without
limitation, by making any counterclaim against the Person asserting the Third Party Claim or any cross-complaint against any Person, in each case only if and to the extent that any such counterclaim or cross-complaint arises from the same actions or
facts giving rise to the Third Party Claim. The Indemnifying Party shall be the sole judge of the acceptability of any compromise or settlement of any claim, litigation or proceeding in respect of which indemnity may be sought hereunder,
provided that the Indemnifying Party will give the Indemnified Party reasonable prior written notice of any such proposed settlement or compromise and will not consent to the entry of any judgment or enter into any settlement with respect to
any Third Party Claim without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld. The Indemnifying Party (if the Indemnified Party is entitled to indemnification hereunder) shall reimburse the Indemnified
Party for its reasonable out of pocket costs incurred with respect to such cooperation. 
  
 If the Indemnifying Party fails to assume the defense of a Third Party Claim within a reasonable period after receipt of written notice pursuant to the first sentence of this subparagraph (c), or if the Indemnifying
Party assumes the defense of the Indemnified Party 
  

 43 

 pursuant to this subparagraph (c) but fails diligently to prosecute or settle the Third Party Claim, then the Indemnified
Party shall have the right to defend, at the sole cost and expense of the Indemnifying Party (if the Indemnified Party is entitled to indemnification hereunder), the Third Party Claim by all appropriate proceedings, which proceedings shall be
promptly and vigorously prosecuted by the Indemnified Party to a final conclusion or settled. The Indemnified Party shall have full control of such defense and proceedings; provided that the Indemnified Party shall not settle such Third Party
Claim without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this
Section, and the Indemnifying Party shall bear its own costs and expenses with respect to such participation. 
  
 Notwithstanding the other provisions of this Section 13.2, if the Indemnifying Party disputes its potential liability to the Indemnified Party
under this Section 13.2 and if such dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party shall not be required to bear the costs and expenses of the Indemnified Party’s defense pursuant to this Section
13.2 or of the Indemnifying Party’s participation therein at the Indemnified Party’s request, and the Indemnified Party shall reimburse the Indemnifying Party in full for all costs and expenses of the litigation concerning such
dispute. If a dispute over potential liability is resolved in favor of the Indemnified Party, the Indemnifying Party shall reimburse the Indemnified Party in full for all costs of the litigation concerning such dispute. 
  
 After it has been determined, by acknowledgment, agreement, or ruling of
court of Legal Requirements, that an Indemnifying Party is liable to the Indemnified Party under this Section 13.2(c), the Indemnifying Party shall pay or cause to be paid to the Indemnified Party the amount of the Liability within ten
business days of receipt by the Indemnifying Party of a notice reasonably itemizing the amount of the Liability but only to the extent actually paid or suffered by the Indemnified Party. 
  
 (d) Survival. The indemnities contained in this Section shall survive the termination and liquidation of the
Partnership. 
  
 (e) Subrogation. In the event of any
payment by or on behalf of an Indemnifying Party to an Indemnified Party in connection with any Liability, the Indemnifying Party (or any guarantor who made such payment) shall be subrogated to and shall stand in the place of the Indemnified Party
as to any events or circumstances in respect of which the Indemnified Party may have any right or claim against any third party (not including the Partnership) relating to such event or indemnification. The Indemnified Party shall cooperate with the
Indemnifying Party (or such guarantor) in any reasonable manner in prosecuting any subrogated claim. 
  
 (f) Nothing in this Agreement shall be deemed to limit the Partnership’s power to indemnify its officers, employees, agents or any other person, to
the fullest extent permitted by law. 
  

 44 

 13.3 Third Party Claim Reimbursement. 
  
 (a) In the case of a Liability relating to a Third Party Claim and caused by
the Fault of a General Partner, its Affiliates or any of their respective officers, directors or employees (acting in their capacities as such) against whom reimbursement is being sought, such General Partner hereby agrees to reimburse the
Partnership for such Liability to the extent that: 
  
 (i) the Liability relates to a Third Party Claim that has been finally resolved and that the Partnership has actually paid (an “Expense”); 
  
 (ii) the Expense is not covered by insurance carried by the Partnership (excluding any amounts relating to
insured claims to the extent that they fall within deductibles or self-insured retentions or are above applicable coverage limits); and 
  
 (iii) the Expense is not offset by third party indemnification or otherwise; 
  
 provided, however, that such General Partner shall reimburse the Partnership for the Expense only to the extent and in
proportion to its Fault. 
  
 (b) Any claim by the Partnership for
reimbursement under this Section may be initiated upon written notice from a Nonconflicted Designating Partner to the General Partner to whom the Partnership is entitled to look for indemnification, and the Designating Partners shall have a period
of 60 days during which to reach unanimous agreement as to the terms on which any reimbursement shall be made. If the Designating Partners are unable to agree or there are any disputes over Fault and reimbursement under this Section, such matters
shall be resolved pursuant to the Dispute Procedures. 
  
 13.4
Dispute Resolution. Except as otherwise provided for herein, all controversies or disputes arising under this Agreement shall be resolved pursuant to the provisions set forth on Appendix D (the “Dispute Procedures”).

  
 13.5 EXTENT OF LIMITATION OF LIABILITY, INDEMNIFICATION,
ETC. TO THE FULLEST EXTENT PERMITTED BY LAW AND WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE LIMITATION OF LIABILITY, INDEMNIFICATION, RELEASE AND ASSUMPTION OBLIGATIONS SET FORTH HEREIN, A PARTY SHALL BE ENTITLED TO INDEMNIFICATION OR RELEASE
HEREUNDER IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE LOSS GIVING RISE TO ANY SUCH INDEMNIFICATION OR RELEASE IS THE RESULT OF THE SOLE, GROSS, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT
OR VIOLATION OF ANY LAW OF OR BY ANY SUCH PARTY. THE PARTIES AGREE THAT THIS STATEMENT CONSTITUTES A CONSPICUOUS LEGEND. 
  
 13.6 Further Assurances. From time to time, each Partner agrees to execute and deliver such additional documents, and will provide such additional
information and assistance, as the Partnership may reasonably require to carry out the terms of this Agreement and to accomplish the Partnership’s business. 
  

 45 

 13.7 Successors and Assigns. Except as may be expressly provided herein, this Agreement shall be
binding upon and inure to the benefit of the successors of the Partners, but no Partner may assign or delegate any of its rights or obligations under this Agreement. Except as expressly provided herein, any purported assignment or delegation shall
be void and ineffective. 
  
 13.8 Benefits of Agreement
Restricted to the Parties. This Agreement is made solely for the benefit of the Partnership and the Partners, and no other Person, including any officer or employee of the Partnership or any Partner, shall have any right, claim or cause of
action under or by virtue of this Agreement.

 13.11 Severability. In the event that any provisions of this Agreement
shall be Finally Determined to be unenforceable, such provision shall, so long as the economic and legal substance of the transactions contemplated hereby is not affected in any materially adverse manner as to any Partner, be deemed severed from
this Agreement and every other provision of this Agreement shall remain in full force and effect. 
  
 13.12 Construction. In construing this Agreement, the following principles shall be followed: (i) no consideration shall be given to the captions
of the articles, sections, subsections or clauses, which are inserted for convenience in locating the provisions of this Agreement and not as an aid in construction; (ii) no consideration shall be given to the fact or presumption that any Partner
had a greater or lesser hand in drafting this Agreement; (iii) examples shall not be construed to limit, expressly or by implication, the matter they illustrate; (iv) the word “includes” and its syntactic variants mean “includes, but
is not limited to” and corresponding syntactic variant expressions; (v) the plural shall be deemed to include the singular, and vice versa; (vi) each gender shall be deemed to include the other gender; and (vii) each appendix, exhibit,
attachment and schedule to this Agreement is a part of this Agreement. 
  
 13.13 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an original, and all of which when taken together shall constitute one and the same original document. 
  
 13.14 Waiver of Right to Partition. Except as provided in Section
12.2(e), each Person who now or hereafter is a party hereto or who has any right herein or hereunder irrevocably waives during the term of the Partnership any right to maintain any action for partition with respect to Partnership property.

  
 13.15 Governing Law. The laws of the State of Delaware
shall govern the construction, interpretation and effect of this Agreement without giving effect to any conflicts of law principles. 
  
 13.16 Jurisdiction; Consent to Service of Process; Waiver. ANY JUDICIAL PROCEEDING BROUGHT AGAINST ANY PARTY TO THIS AGREEMENT OR ANY DISPUTE UNDER
OR ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY MATTER RELATED HERETO SHALL BE BROUGHT IN THE FEDERAL OR STATE COURTS OF THE STATE OF DELAWARE, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE PARTIES TO THIS AGREEMENT
ACCEPTS THE EXCLUSIVE JURISDICTION OF SUCH COURTS AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT (AS FINALLY

 ADJUDICATED) RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT. EACH OF THE PARTIES TO THIS AGREEMENT SHALL APPOINT THE
CORPORATION TRUST COMPANY, THE PRENTICE-HALL CORPORATION SYSTEM, INC. OR A SIMILAR ENTITY (THE “AGENT”) AS AGENT TO RECEIVE ON ITS BEHALF SERVICE OF PROCESS IN ANY PROCEEDING IN ANY SUCH COURT IN THE STATE OF DELAWARE. THE FOREGOING

 13.19 Payment Terms and Interest Calculations. 
  
 (a) If the payment due date for any payment hereunder (including capital contributions and Damages) falls on a Saturday or a
bank or federal holiday, other than a Monday, the payment shall be due on the past preceding business day. If the payment due date falls on a Sunday or Monday bank or federal holiday, the payment shall be due on the following business day.

  
 (b) Interest shall accrue on any unpaid and outstanding amount
from the time such amount is due and payable through the date upon which such amount, together with accrued interest thereon, is paid in full. Interest shall, subject to the provisions of Section 13.20, accrue at a per annum rate equal to the
lesser of (i) the Agreed Rate plus 2%, compounded quarterly, to the extent permitted by law or (ii) the Highest Lawful Rate. 
  
 (c) A wire transfer or delivery of a check shall not operate to discharge any payment under this Agreement and shall be accepted subject to collection.

  
 13.20 Usury Savings Clause. Notwithstanding any other
provision of this Agreement, it is the intention of the parties hereto to conform strictly to Applicable Usury Laws, in each case to the extent they are applicable to this Agreement. Accordingly, if any payment made pursuant to this Agreement
results in any Person having paid any interest in excess of the Maximum Amount, or if any transaction contemplated hereby would otherwise be usurious under any Applicable Usury Laws, then, in that event, it is agreed as follows: (i) the provisions
of this Section 13.20 shall govern and control; (ii) the aggregate of all interest under Applicable Usury Laws that is contracted for, charged or received under this Agreement shall under no circumstances exceed the Maximum Amount, and any
excess shall be promptly refunded to the payor by the recipient hereof; (iii) no Person shall be obligated to pay the amount of such interest 
  

 48 

 to the extent that it is in excess of the Maximum Amount; and (iv) the effective rate of any interest payable under this
Agreement shall be ipso facto reduced to the Highest Lawful Rate, as hereinafter defined, and the provisions of this Agreement immediately shall be deemed reformed, without the necessity of the execution of any new document or
instrument, so as to comply with all Applicable Usury Laws. All sums paid, or agreed to be paid, to any person pursuant to this Agreement for the use, forbearance or detention of any indebtedness arising hereunder shall, to the fullest extent
permitted by the Applicable Usury Laws, be amortized, pro rated, allocated and spread throughout the full term of any such indebtedness so that the actual rate of interest does not exceed the Highest Lawful Rate in effect at any particular time
during the full term thereof. 
  
 13.21 Other Waivers. EACH
PARTY HEREBY WAIVES ANY OBJECTION IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON-CONVENIENS. 
  
 13.22 Special Joinder by OCC. OCC is a party to this Agreement for the sole purpose of evidencing its agreement to be bound by the provisions set
forth in Section 13.9 (Notices) and Section 14 (Lake Charles Facility). OCC is not a partner of the Partnership and shall not have any rights or obligations under this Agreement other than rights and obligations that will apply if
Lyondell (Pelican) LP1 and OCC make the election described in Section 14.1.  
  
 13.23 Amendment. All waivers, modifications, amendments or alterations of this Agreement shall require the written approval of each of the General Partners and each of the Limited Partners. 
  
 13.24 Certain Provisions of Prior Agreement Unaffected. Sections 13.22
and 14 of this Agreement, as amended and restated as of the date hereof, are identical to Sections 13.22 and 14 of the Amended and Restated Partnership Agreement of the Partnership dated as of November 6, 2002 (the “November 2002
Agreement”), and this Agreement does not make any change to the rights and obligations of OCC under the November 2002 Agreement. The November 2002 Agreement (including the definitions therein of applicable defined terms) shall continue in full
force and effect, unaffected hereby, for purposes of Sections 13.24 and 14 thereof. 
  
 SECTION 14 
 LAKE CHARLES FACILITY 
  
 14.1 Lease Not in Force and Effect. At any such time as the Lease is
terminated, expires or is otherwise not in force and effect (other than a No Rebuilding Termination), the following shall occur: 
  
 (a) The number of Units held by Lyondell (Pelican) LP1 shall be reduced from 6,623 Units to 2,541 Units. 
  
 (b) If and to the extent Lyondell (Pelican) LP1 and OCC both so elect in
writing, OCC and the Partnership shall form a general partnership (the “LC Partnership”) by entering into a partnership agreement having the provisions described in Section 14.2 (the “GPA”). Except as
provided in Section 15.1, if Lyondell (Pelican) LP1 and OCC do not make the written election referred to in the immediately preceeding sentence and satisfy their obligations under this Section 14, then the provisions of Section
14.4 shall apply as if Lyondell (Pelican) LP1 had breached its obligations under Section 14.1. 
  

 49 

 (c) The Partnership shall distribute to Lyondell (Pelican) LP1 the balance in its Capital Account.

  
 (d) OCC shall cause the Lake Charles Facility to be
contributed to the LC Partnership, and Lyondell (Pelican) LP1 shall pay to the LC Partnership the amount received pursuant to Section 14.1(c), and OCC shall contribute to the LC Partnership an amount equal to any proceeds of a partial
condemnation of the Lake Charles Facility received by OCC under the terms of the Lease, and the Partnership shall contribute to the LC Partnership the amount received pursuant to Section 26(b) of the Lease in connection with such termination of the
Lease. 
  
 (e) Immediately after and as a result of the foregoing
transactions, the capital account of OCC and the Partnership in the LC Partnership shall be pro rata in accordance with the partners’ equity ownership interests, and Lyondell (Pelican) LP1’s Capital Account shall be the same per Unit as
the Capital Accounts of the other Partners (determined without regard to the special allocations in Sections 4.1(a) through (c)). 
  
 (f) Sections 4.1(e) and (f) shall terminate. 
  
 14.2 LC Partnership Provisions. 
  
 (a) If Lyondell (Pelican) LP1 and OCC make the election described in Section 14.1, then (a) the LC Partnership shall be formed under the laws of
Delaware, (b) the two partners of the LC Partnership shall be the Partnership and OCC and (c) the Partnership shall have an equity ownership interest of 49.9%, and OCC shall have an equity ownership interest of 50.1%. 
  
 (b) The term of the GPA shall be the same as the term of this Agreement.

  
 (c) All issues relating to the LC Partnership must be decided
by mutual agreement of both partners, except that the LC Partnership shall enter into an operating agreement with the Partnership (in its individual capacity), as operator, that shall delegate to the operator the right and obligation to make all
day-to-day decisions of the LC Partnership, which day-to-day decisions shall for this purpose be deemed to be all decisions of the LC Partnership other than issues comparable to those issues set forth in Section 6.7 (which issues must be
decided by the partners of the LC Partnership). Such operating agreement shall provide for the LC Partnership to pay and reimburse the operator for all costs whatsoever incurred or paid by the operator in performing its obligations under the
operating agreement. The term of such operating agreement shall be the same as the term of the LC Partnership. 
  
 (d) All contributions and distributions will be made, and all book income and deductions will be allocated, in accordance with the partners’ equity
ownership interests. Tax items will be allocated between the partners in a manner similar to that set forth in this Agreement. 
  
 (e) No partner in the LC Partnership may transfer (except a transfer to a Wholly Owned Affiliate) or encumber its equity ownership without the consent of
the other partner. 
  

 50 

 14.3 No Rebuilding Termination. Upon a No Rebuilding Termination, OCC, shall have the option to
contribute to the Partnership within 30 days following the No Rebuilding Termination an amount (the “Payment Amount”) equal to the excess, if any, of (a) the Proceeds plus the book value (determined in accordance with GAAP) as
recorded on the books of OCC for that portion and aspect of the Lake Charles Facility that constitutes land, over (b) the payment made pursuant to Section 26(b) of the Lease in connection with such No Rebuilding Termination. If within such 30-day
period Lyondell (Pelican) LP1 contributes the Payment Amount to the Partnership, (i) Lyondell (Pelican) LP1’s 6,623 Units shall remain outstanding, (ii) its Capital Account shall be credited with the Payment Amount, (iii) the assets of the
Partnership shall be revalued so that the Capital Account of each Partner is the same per Unit (determined without regard to the special allocations in Sections 4.1(a) through (c)), and (iv) Sections 4.1(e) and (f) shall terminate. If
Lyondell (Pelican) LP1 does not contribute the Payment Amount to the Partnership within such 30-day period, (A) Lyondell (Pelican) LP1’s 6,623 Units shall be redeemed and canceled and of no further force and effect and (B) an amount equal to
the balance in Lyondell (Pelican) LP1’s Capital Account shall be distributed by the Partnership to Lyondell (Pelican) LP1, or if there is a deficit in Lyondell (Pelican) LP1’s Capital Account, Lyondell (Pelican) LP1 shall contribute to the
Partnership an amount of cash necessary to eliminate such deficit. Upon completion of the steps in clauses (A) and (B), Lyondell (Pelican) LP1’s entire interest in the Partnership shall terminate. 
  
 14.4 Other Redemption. If Lyondell (Pelican) LP1 breaches any of its
obligations under Section 14.1, (a) Lyondell (Pelican) LP1’s 6,623 Units shall be redeemed and canceled and of no further force and effect and (b) an amount equal to the balance in Lyondell (Pelican) LP1’s Capital Account shall be
distributed by the Partnership to Lyondell (Pelican) LP1, or if there is a deficit in Lyondell (Pelican) LP1’s Capital Account, Lyondell (Pelican) LP1 shall contribute to the Partnership an amount of cash necessary to eliminate such deficit.
Upon completion of the steps in clauses (a) and (b), Lyondell (Pelican) LP1’s entire interest in the Partnership shall terminate. In the event of a forfeiture of Lyondell (Pelican) LP1’s 6,623 Units pursuant to this Section 14.4,
the Capital Accounts of the Partners shall be adjusted in accordance with the procedures contained in the definition of “Book Value” prior to determining any deficit or positive Capital Account balance for purposes of this Section
14.4. For purposes of this adjustment, any unamortized portion of the agreed value of the Lease shall be treated as a loss and deducted from Lyondell (Pelican) LP1’s Capital Account. 
  
 SECTION 15 
 ADDITIONAL AGREEMENTS REGARDING THE LAKE CHARLES FACILITY 
  
 15.1 Receipt of Fee Title. Notwithstanding the provisions of Section 14, if at any time the Partnership receives fee title to the Lake

 APPENDIX D 
 TO LIMITED PARTNERSHIP AGREEMENT 
  
 DISPUTE RESOLUTION PROCEDURES 
  
 (1) Binding and Exclusive Means. Except as otherwise provided in the Partnership Agreement, the dispute resolution provisions set forth in this Appendix shall be the binding and exclusive means to resolve all
disputes arising under the Agreement (each a “Dispute”). 
  
 (2) Standards and Criteria. In resolving any Dispute, the standards and criteria for resolving such Dispute shall, unless the Partners involved in the Dispute in their discretion jointly stipulate otherwise, be
as set forth in Appendix 1 to this Appendix. 
  
 (3) ADR
and Binding Arbitration Procedures. If a Dispute arises, the following procedures shall be implemented (with references to “Partners” meaning the Partners involved in the Dispute): 
  
 (a) Any Partner may at any time invoke the dispute resolution procedures set
forth in this Appendix as to any Dispute by providing written notice of such action to the Secretary of the Partnership, who within five Business Days after such notice shall schedule a meeting to be held in Houston, Texas between the Partners. The
Partners’ meeting shall occur within 10 Business Days after notice of the meeting is delivered to the Partners. The meeting shall be attended by representatives of each Partner having decision-making authority regarding the Dispute as well as
the dispute resolution process and who shall attempt in a commercially reasonable manner to negotiate a resolution of the Dispute. 
  
 (b) The representatives of the Partners shall cooperate in a commercially reasonable manner and shall explore whether techniques such as mediation,
minitrials, mock trials or other techniques of alternative dispute resolution might be useful. In the event that a technique of alternative dispute resolution is so agreed upon, a specific timetable and completion date for its implementation shall
also be agreed upon. The representatives will continue to meet and discuss settlement until the date (the “Interim Decision Date”) that is the earliest to occur of the following events: (i) an agreement shall be reached by the
Partners resolving the Dispute; (ii) one of the Partners shall determine and notify the other Partners in writing that no agreement resolving the Dispute is likely to be reached; (iii) if a technique of alternative dispute resolution is agreed upon,
the completion date therefor shall occur without the Partners having resolved the Dispute; or (iv) if another technique of alternative dispute resolution is not agreed upon, two full meeting days (or such other time period as may be agreed upon)
shall expire without the Partners having resolved the Dispute. 
  
 (c) If, as of the Interim Decision Date, the Partners have not succeeded in negotiating a resolution of the Dispute pursuant to subsection (b), the Partners shall proceed under subsections (d), (e) and (f). 
  
 (d) After satisfying the requirements above, such Dispute shall be submitted
to mandatory and binding arbitration at the election of any Partner involved in the Dispute (the “Disputing Partner”). The arbitration shall be subject to the Federal Arbitration Act as supplemented by the conditions set forth in
this Appendix. The arbitration shall be conducted in 
  

 D-1 

 accordance with the Commercial Arbitration Rules of the American Arbitration Association in effect on the date the notice
of arbitration is served, other than as specifically modified herein. In the absence of an agreement to the contrary, the arbitration shall be held in Houston, Texas. The Arbitrator (as defined below) will allow reasonable discovery in the forms
permitted by the Federal Rules of Civil Procedure, to the extent consistent with the purpose of the arbitration. During the pendency of the Dispute, each Partner shall make available to the Arbitrator and the other Partners all books, records and
other information within its control requested by the other Partners or the Arbitrator subject to the confidentiality provisions contained herein, and provided that no such access shall waive or preclude any objection to such production based on any
privilege recognized by law. Recognizing the express desire of the Partners for an expeditious means of dispute resolution, the Arbitrator may limit the scope of discovery between the Partners as may be reasonable under the circumstances. In
deciding the substance of the Partners’ claims, the laws of the State of Delaware shall govern the construction, interpretation and effect of this Agreement (including this Appendix) without giving effect to any conflict of law principles. The
arbitration hearing shall be commenced promptly and conducted expeditiously, with each Partner involved in the Dispute being allocated an equal amount of time for the presentation of its case. Unless otherwise agreed to by the Partners, the
arbitration hearing shall be conducted on consecutive days. Time is of the essence in the arbitration proceeding, and the Arbitrator shall have the right and authority to issue monetary sanctions against any of the Partners if, upon a showing of
good cause, that Partner is unreasonably delaying the proceeding. To the fullest extent permitted by law, the arbitration proceedings and award shall be maintained in confidence by the Arbitrator and the Partners. 
  
 (e) The Disputing Partner shall notify the American Arbitration Association
(“AAA”) and the other Partners in writing describing in reasonable detail the nature of the Dispute (the “Dispute Notice”). The arbitrator (the “Arbitrator”) shall be selected within 15 days of the
date of the Dispute Notice by all of the Partners from the members of a panel of arbitrators of the AAA or, if the AAA fails or refuses to provide a list of potential arbitrators, of the Center for Public Resources and shall be experienced in
commercial arbitration. In the event that the Partners are unable to agree on the selection of the Arbitrator, the AAA shall select the Arbitrator, using the criteria set forth in this Appendix, within 30 days of the date of the Dispute Notice. In
the event that the Arbitrator is unable to serve, his or her replacement will be selected in the same manner as the Arbitrator to be replaced. The Arbitrator shall be neutral. The Arbitrator shall have the authority to assess the costs and expenses
of the arbitration proceeding (including the arbitrators’, and attorneys’ fees and expenses) against any or all Partners. 
  
 (f) The Arbitrator shall decide all Disputes and all substantive and procedural issues related thereto, and shall enforce this Agreement in accordance
with its terms. Without limiting the generality of the previous sentence, the Arbitrator shall have the authority to issue injunctive relief; however, the Arbitrator shall not have any power or authority to (i) award consequential, incidental,
indirect or punitive damages or (ii) amend this Agreement. The Arbitrator shall render the arbitration award, in writing, within 20 days following the completion of the arbitration hearing, and shall set forth the reasons for the award. In the event
that the Arbitrator awards monetary damages in favor of either party, the Arbitrator must certify in the award that no indirect, consequential, incidental, indirect or punitive damages are included in such award. If the Arbitrator’s decision
results in a monetary award, the interest to be granted on such award, if any, and the rate of such interest shall be determined by the Arbitrator in his or her discretion. 
  

 D-2 

 The arbitration award shall be final and binding on the Partners, and judgment thereon may be entered in any court of
competent jurisdiction, and may not be appealed except to the extent permitted by the Federal Arbitration Act. 
  
 (4) Continuation of Business. Notwithstanding the existence of any Dispute or the pendency of any procedures pursuant to this Appendix, the
Partners agree and undertake that all payments not in dispute shall continue to be made and all obligations not in dispute shall continue to be performed. 
  

 D-3 

 APPENDIX 1 TO Appendix D 
  
 (a) First priority shall be given to maximizing the consistency of the resolution of the Dispute with the satisfaction of
all express obligations of the Partners and their Affiliates as set forth in the Partnership Agreement. 
  
 (b) Second priority shall be given to resolution of the Dispute in a manner which best achieves the objectives of the business activities and arrangements
under the Partnership Agreement and the Related Agreements and permits the Partners to realize the benefits intended to be afforded thereby. 
  
 (c) Third priority shall be given to such other matters, if any, as the Partners or the Arbitrator shall determine to be appropriate under the
circumstances. 
  

 D-4 

 APPENDIX E 
 TO LIMITED PARTNERSHIP AGREEMENT 
  
 DIVISION OF PARTNERSHIP BUSINESS 
  
 If the Partnership is dissolved and Section 12.2(e) applies to the winding up of the affairs of the Partnership, the Partnership properties shall, to the extent legally and contractually feasible and, after
satisfaction of the liabilities of the Partnership (whether by payment or reasonable provision for payment), be distributed in kind to the Partners in accordance with a division (the “Division”) of the properties. The Division shall
be implemented by dividing the properties, to the extent feasible, in accordance with the following priorities and principles: 
  

	A.	First priority shall be given to maximizing the consistency of the Division with a division of the Partnership properties that allocates to each Partner (subject to such
Partner’s Percentage Interest of the Partnership’s liabilities) Partnership properties in proportion to the value of such Partner’s Percentage Interest in the Partnership’s business taking into account the aggregate Asset Fair
Market Value of the Partnership’s properties and the value and benefits afforded to such Partner under the Partnership Agreement and the other Related Agreements. 

  

	B.	Second priority shall be given to the allocation of the Partnership’s various assets and business units between the Partners so as to maximize the aggregate going concern value
of the respective assets and business units allocated to each Partner, taking into account, without limitation, the potential synergies and efficiencies that are reasonably achievable in connection with the operation of such allocated assets and
business units as an independent business entity. 

  

	C.	Third priority shall be given to maximizing the consistency of the Division with the nature and quality of the Assets and Contributed Business originally transferred to the
Partnership by the respective Partners or their Affiliates. 

  
 Absent an agreement by the Partners or direction by the Neutral as to both (i) how the Partners should allocate Partnership debt and (ii) the process for relieving each Partner of liability for that portion of
Partnership debt allocated to the other Partner, the Partners (A) shall be jointly and severally liable to the holders of all Partnership debt and (B) as between the Partners, each Partner shall be obligated to pay to holders of the debt its
Percentage Interest of all payments of principal and interest on Partnership Debt. Notwithstanding the foregoing, the Neutral shall be entitled to direct, and any Partner may propose, an alternative allocation of Partnership debt in any circumstance
where such alternative allocation is reasonably likely to result in a Division that is more consistent with the priorities outlined above. 
  
 For purposes of this Appendix E, Lyondell LP4 and its Affiliated Limited Partners shall be treated as if they were a single Partner and Millennium GP and
Millennium LP shall be treated as if they were a single Partner. 
  
 The Partners shall attempt to agree on a plan for a mutually acceptable Division. If they are unable to so agree after 60 days following the occurrence of the dissolution, a Neutral shall be appointed in accordance with Appendix J) and each
Partner shall submit to the Neutral a 
  

 E-1 

 written proposal for a Division. The Neutral shall decide which of the two proposals (without in anyway modifying or
compromising between the two proposals) more closely follows the priorities and principles. set forth above, and the proposal so chosen shall thereupon be binding Upon all Partners and shall be promptly implemented Under the direction of the
Neutral. The Neutral shall be entitled to employ (at the expense of the Partnership) such financial and accounting advisors and shall counsel as he or she shall select, provided that no such advisor or counsel shall have any affiliation with any
Partner.

 SCHEDULE 8.6(A) 
  
 FORM OF INDEMNITY 
  
 THIS INDEMNITY (this “Indemnity”) by [insert name of Millennium indemnitor], a [insert state] corporation (“Millennium
Indemnitor”), is in favor of EQUISTAR CHEMICALS, LP, a Delaware limited partnership (the “Partnership”). 
  
 RECITALS: 
  
 A. The indemnity provided in this Indemnity reasonably may be expected to benefit, directly or indirectly, Millennium Indemnitor. Further, it is in the
best interests of Millennium Indemnitor to provide the indemnity set forth hereunder, and such indemnity is necessary or convenient to the conduct, promotion or attainment of the business of Millennium Indemnitor. 
  
 B. This Indemnity is issued pursuant to Section 8.6(b) of the Amended and
Restated Limited Partnership Agreement of the Partnership, dated as of November 6, 2002, among Lyondell Petrochemical G.P. Inc., Lyondell Petrochemical L.P. Inc., Millennium Petrochemicals GP LLC (“Millennium GP”), Millennium

 AGREEMENTS:

  
 NOW, THEREFORE, Millennium Indemnitor hereby agrees as
follows: 
  
 1. Notwithstanding any other
provision of this Indemnity but subject to paragraph 6 below, Millennium Indemnitor shall be obligated to the Partnership to pay the Contribution Obligation to the Partnership only after the holders of the Debt shall have pursued their remedies to
compel payment of the Referenced Obligation by the Issuers, and if, after exhaustion of all available remedies, including, without limitation, the liquidation of assets, payment cannot be obtained from the Issuers. For purposes of this Indemnity,
the term “Issuers” shall have the meaning set forth in the Debt. 
  
 2. The obligations of Millennium Indemnitor hereunder to the Partnership shall not be subject to any reduction, limitation, impairment or
termination for any reason, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever, by reason of the invalidity, illegality or unenforceability of the Referenced Obligation, any impossibility in the
performance of the Referenced Obligation or otherwise, subject to paragraph 6 below. Without limiting the generality of the foregoing, except as aforesaid, the obligations of Millennium Indemnitor hereunder shall not be discharged or impaired or
otherwise affected by any waiver or modification of any of the Referenced Obligation, by any default, failure or delay, willful or otherwise, in the performance of the Referenced Obligation, or by any other act or omission which may or might in any
manner or to any extent vary the risk of Millennium Indemnitor or otherwise operate as a discharge of Millennium Indemnitor as a matter of law or equity. 
  

 1 

 3. Millennium Indemnitor further agrees that its obligations hereunder shall continue to
be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Referenced Obligation is rescinded or must otherwise be restored by the Partnership upon the bankruptcy or reorganization of an Issuer or
otherwise, unless those obligations of Millennium Indemnitor have otherwise been terminated in accordance with the terms of this Indemnity.  
  
 4. The Partnership agrees that it shall not assign any of its right, title and interest in and to this Indemnity. This Indemnity shall not
be construed to create any right in the holders of the Debt or any other person (other than Millennium Indemnitor, the Partnership, [insert the names of the non-Millennium partners], and, in each case, their respective successors and
permitted assigns), or to be a contract in whole or in part for the benefit of the holders of the Debt, or any other person except the Partnership. Accordingly, the holders of the Debt shall not, by reason of this Indemnity, have a greater or
superior claim compared to other obligees of the Partnership, to or as a result of any amounts contributed by Millennium Indemnitor to the Partnership pursuant to this Indemnity.  
  
 5. Notwithstanding any other provision of this Indemnity,
this Indemnity shall terminate on [insert the termination date or mechanism].  
  
 6. This Indemnity shall be construed and interpreted in accordance with and governed by the laws of the State of [insert state].
 
  
 7. This Indemnity may be
executed in one or more counterparts, each of which shall constitute an original and all of which when taken together shall constitute one and the same original document.  
  
 8. The existence of this Indemnity shall not prohibit the Partnership from refinancing or repaying any Debt
at any time, subject to the other provisions of the Partnership Agreement.  
  
 9. Nothing in this Indemnity shall be construed or interpreted to amend the Partnership Agreement in any respect.

Agreement”); 
  
 WHEREAS, the purpose of this
Agreement is to carry out the intention of the parties hereto that, if the assets of the Partnership are insufficient to discharge the Partnership’s liabilities, then to the extent and in the amount provided in the Millennium Indemnity,
Millennium Indemnitor shall be ultimately responsible for any liabilities of the Partnership that remain unpaid; 
  
 NOW, THEREFORE, the parties to this Agreement agree as follows: 
  
 1. Millennium Indemnity. If any Partner, former Partner or a Related Person of any Partner or former Partner is
required to pay any portion of the Referenced Obligation (whether paid directly, as a result of the Partner’s deficit restoration obligation set forth in Section 12.2(d)(ii) of the Partnership Agreement or the Partner’s right of
contribution or otherwise) and, as a result, the amount Millennium Indemnitor would otherwise be required to pay pursuant to the Millennium Indemnity is reduced, then Millennium Indemnitor shall pay to such Partner, former Partner or Related Person
an amount equal to such reduction. For purposes of the Partnership Agreement, any payment made pursuant to this Section 1 shall be treated as a contribution by the Millennium Indemnitor to the Partnership for the benefit of the Millennium partner
named in the Millennium Indemnity, and a distribution by the Partnership to the Partner to which any such payment is made. 
  
 2. Duration of Obligations. Except with respect to any amount then owing, the obligations of Millennium Indemnitor under Section 1 hereof shall
terminate immediately upon the termination of the Millennium Indemnity. 
  
 3. Definitions. For purposes of this Agreement, 
  
 (a) the assets of the Partnership do not include (i) the obligation of any Partner to make contributions to the Partnership (including as a result of the Partner’s deficit restoration obligation set forth in Section 12.2(d)(ii) of the
Partnership Agreement); (ii) the obligations of [identify parties to the Parent Agreement] under the [identify the then current version of the Parent Agreement]; (iii) the obligations of Millennium Indemnitor under the Millennium
Indemnity; and (iv) the obligations of any Partner or Related Person to perform under any other guarantee or similar obligation; 
  

 1 

 (b) “Millennium Indemnity” means that indemnity provided to the Partnership by
[insert name of Millennium indemnitor] pursuant to the Indemnity dated as of [insert date]; 
  
 (c) “Partner” has the meaning set forth in the Partnership Agreement; 
  
 (d) “Referenced Obligation” has the meaning set forth in the Millennium Indemnity; and 
  
 (e) “Related Person” with respect to any Partner, has the
meaning set forth in Treasury Regulation §1.752-4(b). 
  
 4.
No Third Party Beneficiaries. This Agreement is made solely for the benefit of the parties hereto and the Related Persons and any former partner referred to herein, and no other person, including the Partnership or any creditor of the
Partnership, shall have any right, claim, or cause of action under or by virtue of this Agreement. 
  
 5. Counterparts. This Agreement may be executed in one or more counterparts, each of which when taken together shall constitute one and the same
original document. 
  
 6. Governing Law. The laws of the
State of Delaware shall govern the construction, interpretation and effect of this Agreement without giving effect to any conflicts of law principles. 
  
 7. Refinancing or Repaying Debt. The existence of this Agreement shall not prohibit the Partnership from refinancing or repaying any Debt (as
defined in the Millennium Indemnity) at any time, subject to the other provisions of the Partnership Agreement. 
  
 8. No Amendment to the Partnership Agreement. Nothing in this Agreement shall be construed or interpreted to amend the Partnership Agreement in any

 WHEREAS, pursuant to an Agreement and Plan of Merger dated March 28, 2004
(the “Merger Agreement”), among Lyondell, Millennium and Millennium Subsidiary LLC, a limited liability company duly formed and existing under the laws of the State of Delaware formerly known as Aries Subsidiary LLC (“Millennium

Section 15.06 of the Indenture. 

 NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH: 
  
 For and in consideration of the premises, it is mutually agreed, for the
equal and proportionate benefit of the respective holders from time to time of the Debentures, as follows: 
  
 ARTICLE ONE 
 DEFINITIONS 
  

	SECTION	1.1. Indenture Terms. 

  
 Except as set forth in Section 1.2, capitalized terms used but not defined in this First Supplemental Indenture shall have the respective meanings

	SECTION	1.2. Certain Definitions. 

  
 From and after the effective time of this First Supplemental Indenture, the definitions of the following terms set forth in Article I of the Indenture
shall be amended and restated to read in full as follows: 
  
 “Board of Directors” means the Board of Directors of the Company or a committee of such Board duly authorized to act for it hereunder or, if such term is used in reference to Lyondell, the Board of Directors of Lyondell or a
committee of such Board duly authorized to act for it hereunder. 
  
 “Common Stock” means any stock of any class of Lyondell which has no preference in respect of dividends or of amounts payable in the event of any voluntary or involuntary liquidation, dissolution or winding up of Lyondell and
which is not subject to redemption by Lyondell. Subject to the provisions of Section 15.06, however, shares issuable on conversion of Debentures shall include only shares of the class designated as Common Stock of Lyondell at November 30, 2004
(namely, the Common Stock, par value $1.00 per share) or shares of any class or classes resulting from any reclassification or reclassifications thereof and which have no preference in respect of dividends or of amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or winding up of Lyondell and which are not subject to redemption by Lyondell; provided that if at any time there shall be more than one such resulting class, the shares of each such class then so
issuable on conversion shall be substantially in the proportion which the total number of shares of such class resulting from all such reclassifications bears to the total number of shares of all such classes resulting from all such
reclassifications. The term “Common Stock” shall not mean shares of Series B Common Stock, par value $1.00 per share, of Lyondell.
