8.7 TREATMENT OF CERTAIN INDEMNITY PAYMENTS.

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

(b) If a Member makes any payment to a third party that is subject to indemnification by the Company pursuant to the Contribution Agreement or Annex B or C thereto (a “Member Indemnifiable Payment”), the Members intend that the tax consequences of such Member Indemnifiable Payment and the indemnification payment itself shall inure to the Company and be shared by the Members in accordance with their respective Percentage Interests, but, except as otherwise agreed by the Members, only to the extent that such tax results can be achieved without causing the Capital Accounts of the Class C Members in the aggregate and the Capital Accounts of the Class P Members in the aggregate to fail to be equal.

8.8 TREATMENT OF CERTAIN DEFERRED CAPITAL CONTRIBUTIONS. As a result of the K-Resin Accident, the value of certain assets contributed by the Class P Members at Closing had declined from that which existed when the Members were first agreeing on the economic terms of the arrangement described in this Agreement. The Members could not agree on the amount of the decline in value, in part because they were unable to reach an agreement on the likely time and expense involved in repairing the damage caused by the K-Resin Accident and the degree and permanence of any loss of customers that the K-Resin Accident may cause. In order to resolve the issue, it was agreed that one or more of the Class P Members might have to make capital contributions to the Company after the Closing under the circumstances and in the amounts calculated under the provisions of the Contribution Agreement. The Members view such deferred capital contributions as necessary to preserve the pre K-Resin Accident value of the business and assets contributed by the Class P Members. The Members agree that any deferred contributions are capital contributions and will not be reported as income by the Company.

8.9 SPECIAL RULE. An Indemnifying Party will indemnify the Indemnified Party on a Net After-Tax Basis against any income or franchise tax incurred in the event that any indemnification payment is treated as taxable income to the Indemnified Party. For purposes of this paragraph, “Net After-Tax Basis” means after any U.S. federal, state or local income or franchise taxes (computed using the Tax Rate) incurred as a result of such indemnification (assuming the deductibility of such state and local income and franchise taxes in calculating federal income tax), reduced by any tax benefit arising as a result of such indemnification.

24

8.10 APPLICATION OF THE BASKET, TAX BASKET AMOUNT AND CAP. No provision of this Agreement or the Contribution Agreement (including the Annexes thereto) shall be applied or interpreted in a manner that would cause any indemnification payment to be made that otherwise would not be payable because of application of the Basket, Tax Basket Amount or the Cap.

ARTICLE 9

ALLOCATION OF PROFITS AND LOSSES; DISTRIBUTIONS; TAX AND

ACCOUNTING MATTERS

9.1 ALLOCATIONS. Net Profit and Net Loss of the Company shall be determined and allocated with respect to each Fiscal Year, Fiscal Quarter or other period of the Company as follows:

(a) GENERAL ALLOCATION. Except as otherwise provided in this Article 9, Net Profit and Net Loss for each Fiscal Year, Fiscal Quarter or other period shall be allocated to the Members in accordance with their Percentage Interests.

(b) REGULATORY ALLOCATIONS. Notwithstanding the foregoing, the following special allocations shall be made for each Fiscal Year or other period in the following order of priority:

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

(ii) If there is a net decrease in Member Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during any Company taxable year, each Member who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with section 1.704-2(i)(5) of the Income Tax Regulations, shall be specially allocated items of Company income and gain for such taxable year (and, if necessary, subsequent years) in the amount equal to such Member’s share of net decrease in Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in a manner consistent with the provisions of section 1.704-2(i)(4) of the Income Tax Regulations. This subsection (b)(ii) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement of section 1.704-2(i)(4) of the Income Tax Regulations and shall be interpreted consistently therewith.

25

(iii) If any Member unexpectedly receives (or Members unexpectedly receive) an adjustment, allocation or distribution of the type contemplated by section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) of the Income Tax Regulations, items of income and gain shall be allocated to such Member (or if more than one Member receives such an adjustment, allocation or distribution, items of income and gain shall be allocated to such Members in proportion to the amounts of their respective Adjusted Capital Account Deficits) in an amount (or amounts) and manner sufficient to eliminate the Adjusted Capital Account Deficit of such Member (or deficits of such Members) as quickly as possible. It is intended that this subsection (b)(iii) qualify and be construed as a “qualified income offset” within the meaning of section 1.704-1(b)(2)(ii)(d) of the Income Tax Regulations.

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

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

(vi) Nonrecourse Deductions for any Fiscal Year or other period shall be allocated to the Members in proportion to their respective Percentage Interests.

(vii) To the extent an adjustment to the adjusted tax basis of any Company asset, pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to section 1.704-1(B)(2)(IV)(M)(2) or 1.704-1(b)(2)(iv)(M)(4) of the Income Tax Regulations, to be taken into account in determining Capital Accounts as the result of a distribution to a Member in compete liquidation of such Member’s interest in the Company, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss

26

shall be specially allocated to the Members in accordance with their interests in the Company in the event section 1.704-1(b)(2)(iv)(M)(2) of the Income Tax Regulations applies, or to the Member to whom such distribution was made in the event section 1.704-1(b)(2)(iv)(M)(4) of the Income Tax Regulations applies

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

(c) TAX ALLOCATIONS.

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

(ii) SECTION 704(C). In accordance with section 704(c) of the Code and the Income Tax Regulations thereunder, income, gain, loss and deduction with respect to any property contributed to the capital of the Company shall, solely for income tax purposes, be allocated so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and the initial Carrying Value of such property. If the Carrying Value of any Company property is adjusted as described in the definition of “Carrying Value”, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and the Carrying Value of such asset in the manner prescribed under Sections 704(b) and 704(c) of the Code and the Income Tax Regulations thereunder. With respect to assets contributed or required to be contributed by the Members at the Closing pursuant to the Contribution Agreement, for purposes of applying section 704(c) of the Code and this Section 9.1(c)(ii), the Company shall use the traditional method with curative allocations set forth in section 1.704-3(c) of the Income Tax Regulations. Any elections or other decisions relating to such allocations shall be made by the Board of Directors.

(d) DEPRECIATION RECAPTURE. Solely for tax purposes, a Member’s share of the Company’s depreciation recapture recognized for tax purposes upon the disposition of Company property shall be computed in the manner provided for in sections 1.704-3(a)(11), 1.1245-1(e) and 1.1250-1(f) of the Income Tax Regulations. The provisions of this Section 9.1(d) are intended to affect only the character of the items of gain allocated by the Company to

27

the Members. This Section 9.1(d) shall not affect the aggregate amount of gain (including gain characterized under this Section 9.1(d) as depreciation recapture) otherwise allocable to a Member pursuant to this Section 9.1.

(e) CHANGE IN PERCENTAGE INTERESTS. Except as otherwise required by law, if the Percentage Interests of the Members of the Company are changed during any taxable year, all items to be allocated to the Members for such entire taxable year shall be prorated on the basis of the portion of such taxable year which precedes each such change and the portion of such taxable year on and after each such change according to the number of days in each such portion, and the items so allocated for each such portion shall be allocated to the Members in the manner in which such items are allocated as provided in Section 9.1(a) during each such portion of the taxable year in question.

(f) EXCESS NONRECOURSE LIABILITIES. Nonrecourse liabilities of the Company that constitute “excess nonrecourse liabilities” within the meaning of section 1.752-3(a)(3) of the Income Tax Regulations, shall be allocated among the Members in proportion to their respective Percentage Interests.

(g) ALLOCATIONS IN RESPECT OF PREFERRED INTERESTS. Commencing on the date of this Agreement, for each Fiscal Year, Fiscal Quarter, or other period of the Company, before any allocation pursuant to Section 9.1(a), Net Profits for such period shall be allocated to the Members holding Preferred Interests pro rata in accordance with their respective Preferred Percentage Interests until the cumulative amount of Net Profits allocated in respect of the Preferred Percentage Interests pursuant to this section for the current Fiscal Year and all prior Fiscal Years or portions thereof equals the cumulative amount of Preferred Distributions made pursuant to Section 9.2(i) for all periods up to and including the period in which the allocation of Net Profits under this Section is being made. Net Losses shall not be allocated to a Member holding a Preferred Interest to the extent the allocation of Net Losses would cause the Capital Account of such Member to be less than the sum of such Member’s Unpaid Preferred Yield and Unrecovered Preferred Contribution.

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

(i) First, in an amount equal to the Unpaid Preferred Yield up to the date of such allocation.

(ii) Second, to each Member owning a Preferred Interest in the ratio that its Unrecovered Preferred Contribution bears to the aggregate Unrecovered Preferred Contributions of all Members up to an amount that causes the Capital Account of each Member owning a Preferred Interest to equal its respective Unrecovered Preferred Contribution. For purposes of this Section 9.1(h)(ii), Capital Accounts shall be computed by excluding therefrom allocations of items of income, gain, loss and deduction made under Sections 9.1(h)(i).

28

(iii) Last, in such amounts as shall cause (A) the ratio of the Capital Account of each Member to the aggregate Capital Accounts of all Members to (B) equal as nearly as possible each Member’s respective Percentage Interest. For purposes of this Section 9.1(h)(iii), Capital Accounts shall be computed by excluding therefrom allocations of items of income, gain, loss and deduction made under Sections 9.1(h)(i) and (ii).

(i) STATE AND LOCAL ITEMS. Items of income, gain, loss, deduction, credit and tax preference for state and local income tax purposes shall be allocated to and among the Members in a manner consistent with the allocation of such items for federal income tax purposes in accordance with the foregoing provisions of this Section 9.1.

9.2 DISTRIBUTIONS.

(a) The Company shall distribute to each Member as promptly as practicable (and in any event within forty-five (45) days) after the end of each of the first three (3) Fiscal Quarters of each Fiscal Year of the Company an amount equal to such Member’s Quarterly Tax Distribution for such Fiscal Quarter. In addition, the Company shall distribute to each Member as promptly as practicable (and in any event within forty-five (45) days) after the end of each Fiscal Year an amount equal to the excess, if any, of such Member’s Proportionate Tax Share for such Fiscal Year over the aggregate amount of Quarterly Tax Distributions made to such Member with respect to such Fiscal Year.

(b) At the end of each of the second Fiscal Quarter and the fourth Fiscal Quarter, the Board of Directors shall determine if a Leverage Ratio Deficit exists. If a Leverage Ratio Deficit exists, the Board of Directors, as promptly as practicable after the end of such Fiscal Quarter, shall meet and take such action as the Directors deem necessary to reduce the Leverage Ratio Deficit to zero. If the Board of Directors fails to reduce the Leverage Ratio Deficit to zero within forty-five (45) days following the end of the second or fourth Fiscal Quarter, the Chief Executive Officer shall cause the Company to distribute to the Members in proportion to their relative Percentage Interests an amount equal to the Minimum Leverage Distribution for the applicable six-month period.

(c) Any distributions by the Company to the Members, other than the Tax Distribution, the Minimum Leverage Distribution and any distributions of a Mandatory Redemption Payment, shall be payable at the discretion of the Board of Directors.

(d) To the extent the Company is required by law to withhold or to make tax payments on behalf of or with respect to any Member, the Company may withhold such amounts and make such tax payments as so required. For purposes of this Agreement, any such payments or withholdings shall be treated as a distribution to the Member on behalf of whom the withholding or payment was made.

(e) Notwithstanding anything to the contrary contained in this Section 9.2, the Company shall not make any distribution to the Members which would render the Company insolvent or which is otherwise prohibited by applicable law.

29

(f) Subsequent to the Closing, the Company made distributions to the Members as provided in Section 9.2(f) of the Amended & Restated LLC Agreement, and, after such distributions, the aggregate Capital Accounts of the Class C Members remained equal to the aggregate Capital Accounts of the Class P Members. The Company will use its best efforts to avoid taking any action that, or failing to take any action the failure of which to take, is likely to cause all or part of the distributions made pursuant to Section 9.2(f) of the Amended & Restated LLC Agreement to be taxable to one or more of the Members and in connection therewith the Members shall cooperate with the Company and each other.

(g) In the event that, within two years of the Closing or any contribution of an asset to the Company, the Members desire for the Company to make a distribution or payment to any of the Members or pay all or a portion of any liability, and if such distribution or payment to a Member or such payment of a liability may give rise to a disguised sale under section 707(a)(2)(B) of the Code or corresponding provision of state or local law, the Members shall cooperate to avoid such result without changing the intended economics of the arrangement.

(h) FORMATION AND REIMBURSEMENT FOR CAPITAL EXPENDITURES.

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

(ii) If, absent this Section 9.2(h), any distribution to a Class P Member would cause any of the P Chem property transferred by that Member to the Company pursuant to the Contribution Agreement to be treated as a sale of such property, or if, absent this Section 9.2(h), any distribution to a Class C Member would cause any of the C Chem property transferred by that Member to the Company pursuant to the Contribution Agreement to be treated as a sale of such property, then, to the extent permitted by Regulations Section 1.707-4(d), the Company and the Members shall treat such distribution as a reimbursement of Reimbursable Capital Expenditures made by such Member (up to the amount thereof as set forth on Schedule 3 less any portion of such amount that has been reimbursed by any prior distribution treated as a reimbursement of Reimbursable Capital Expenditures under this Section 9.2(h)).

30

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

(i) PREFERRED DISTRIBUTIONS.

(i) A preferred return (“Preferred Yield”) shall accrue with respect to each Preferred Interest at the rate of 9.0% per annum on the Unrecovered Preferred Contribution of the Member holding such Preferred Interest. Subject to the Board of Directors’ discretion to declare distributions as provided in Section 9.2(c), each Member holding a Preferred Interest shall be entitled to receive distribution of its respective Preferred Yield as and when declared by the Board of Directors (“Preferred Distributions”). Preferred Distributions are payable only to the extent that the Company has funds on hand legally available therefor.

(ii) The Preferred Yield will (A) accrue and accumulate from the most recent date on which all accrued and unpaid Preferred Yield has been paid or, if no Preferred Yield has been paid, from and including July 1, 2002; (B) be payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, commencing on September 30, 2002, except to the extent any such payment is deferred as permitted under Section 9.2(c); and (C) be payable from the Company’s positive Cash Earnings, but only to the extent of the Company’s Net Profits for any Fiscal Quarter.

31

(iii) The amount of any Preferred Yield for any period will be computed on the basis of a 360-day year consisting of twelve 30-day months and for any period of less than a full calendar month on the basis of the actual number of days elapsed in such month. If any date on which Preferred Distributions are payable is not a Business Day, then payment of the amount payable on such date shall be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date such payment was originally payable (each date on which a Preferred Distribution is payable in accordance with the foregoing, a “Preferred Distribution Date”).

(iv) Each Preferred Distribution will be payable to the holders of Preferred Interests as they appear on the Company’s books and records as of the close of business on the record date for such Preferred Distribution, which shall be the Business Day before such Preferred Distribution Date.

(v) The Company shall notify each Member as promptly as practicable upon determining that a Preferred Distribution is required under this Section 9.2(i). Such notice shall specify as to each Member the amount of such Preferred Distribution and the relevant Preferred Distribution Date

(j) MANDATORY REDEMPTION OF PREFERRED INTERESTS.

(i) Subject to the restriction in Section 9.2(e), if, in any Fiscal Quarter, the Company has achieved the Preferred Target Ratio, the Company shall redeem Preferred Interests by making cash distributions in return of $25,000,000 of Preferred Contributions and, in addition, shall pay all Unpaid Preferred Yield on such amount of Preferred Contributions to the Mandatory Redemption Payment Date therefor (each such payment, a “Mandatory Redemption Payment”). Each Mandatory Redemption Payment shall be apportioned among the Members pro rata according to their respective Preferred Percentage Interests. Upon distribution of each Mandatory Redemption Payment, (A) the Preferred Contributions of each Member holding a Preferred Interest shall be reduced by an amount equal to the Mandatory Redemption Payment apportioned to it less any amount of the Mandatory Redemption Payment distributed in payment of Unpaid Preferred Yield and (B) such Member’s Preferred Percentage Interest shall be reduced accordingly.

(ii) The Company shall notify each Member as promptly as practicable upon determining that a Mandatory Redemption Payment is required under this Section 9.2(j). Such notice shall specify as to each Member the amount of such Mandatory Redemption Payment, the date upon which such Mandatory Redemption Payment shall be made (the “Mandatory Redemption Payment Date”), and the amount of Unpaid Preferred Yield to be included in such payment.

32

(iii) The Company shall distribute each Mandatory Redemption Payment to the Members as promptly as practicable (and in any event within forty-five (45) days) after the end of each Fiscal Quarter in which it achieves the Preferred Target Ratio.

(iv) Each Mandatory Redemption Payment will be distributable to the holders of Preferred Interests as they appear on the Company’s books and records as of the close of business on the Business Day before the relevant Mandatory Redemption Payment Date.

(v) Except as provided in Section 9.2(j)(i), no Member may require the Company to redeem all or any part of its Preferred Interest.

(k) RIGHT OF OPTIONAL REDEMPTION OF PREFERRED INTEREST.

(i) In addition to its mandatory redemption obligations under Section 9.2(j)(i) above, the Company also shall have the right, exercisable in its sole and absolute discretion, to redeem Preferred Interests, in whole or in part, at any time by making cash distributions in return of Preferred Contributions and, in addition, by paying all Unpaid Preferred Yield on such amount of Preferred Contributions, in each case to the date of such optional redemption distribution (this right being the “Right of Optional Redemption”). The Right of Optional Redemption does not limit the Company’s obligations under Section 9.2(j)(i).

(ii) To exercise its Right of Optional Redemption, the Company shall declare the amount of Preferred Contributions to be returned and amount of Unpaid Preferred Yield thereon to the Optional Redemption Payment Date therefor (the “Optional Redemption Amount”). Distributions of the Optional Redemption Amount shall be apportioned among the Members according to their respective Preferred Percentage Interests. Upon each distribution of an Optional Redemption Amount, (A) the Preferred Contribution of each Member holding a Preferred Interest shall be reduced by an amount equal to the Optional Redemption Amount apportioned to it less any amount of the Optional Redemption Amount distributed in payment of Unpaid Preferred Yield and (B) such Member’s Preferred Percentage Interest shall be reduced accordingly.

(iii) The Company shall not declare any redemption of less than ten million dollars ($10,000,000) of Preferred Contributions.

(iv) The Company shall notify each Member as promptly as practicable upon determining that it will exercise its Right of Optional Redemption under this Section 9.2(k). Such notice shall specify as to each Member the Optional Redemption Amount, the date upon which such redemption shall be made (the “Optional Redemption Payment Date”), and the amount of Unpaid Preferred Yield to be included in such payment.

(v) The Company shall distribute the Optional Redemption Amount as promptly as practicable (and in any event within fifteen (15) days) after determining to exercise the Right of Optional Redemption.

33

(vi) Each Optional Redemption Amount will be distributable to the holders of Preferred Interests as they appear on the Company’s books and records as of the close of business on the Business Day before the relevant Optional Redemption Payment Date.

(l) PREFERRED INTERESTS TO BE RETIRED UPON REDEMPTION IN FULL. When (i) all Unpaid Preferred Yield has been distributed and (ii) the Company has returned all Preferred Contributions (whether pursuant to this Section 9.2(j)(i) or pursuant to Section 9.2(k)), the Preferred Interests shall be deemed to be retired, and the Members shall have no further rights with respect to such Preferred Interests.

9.3 ACCOUNTING MATTERS. The Company’s tax year shall be the calendar year unless otherwise required by section 706 of the Code or the Income Tax Regulations thereunder. The Board of Directors shall cause to be maintained complete books and records accurately reflecting the accounts, business and transactions of the Company on a calendar-year basis and using such cash, accrual, or hybrid method of accounting as in the judgment of the Board of Directors is most appropriate; provided, however, that books and records with respect to the Company’s Capital Accounts and allocations under this Agreement of Net Profit and Net Loss (and items entering into the determination thereof) and income, gain, loss, deduction or credit (or item thereof) shall be kept on the basis of the Company’s Fiscal Year and under United States federal income tax accounting principles as applied to partnerships.

9.4 TAX STATUS AND RETURNS.

(a) Any provision hereof to the contrary notwithstanding, solely for United States federal income tax purposes, each of the Members hereby recognizes that the Company is subject to all provisions of Subchapter K of Chapter 1 of Subtitle A of the Code; provided, however, that the filing of U.S. Partnership Returns of Income shall not be construed to expand the purposes of the Company or expand the obligations or liabilities of the Members.

(b) The chief financial officer shall prepare or cause to be prepared all tax returns and statements, if any, that must be filed on behalf of the Company with any taxing authority, and shall make timely filing thereof. Within one-hundred eighty (180) days after the end of each calendar year, the Company shall cause to be prepared and delivered to each Member a report setting forth in reasonable detail the information with respect to the Company during such calendar year reasonably required to enable each Member to prepare its federal, state and local income tax returns in accordance with applicable law then prevailing.

9.5 754 ELECTION AND OTHER TAX ELECTIONS. In the event of a distribution of property to a Member, or a transfer of any interest in the Company permitted under the Act or this Agreement, the Company, upon the written request of the transferor or transferee, shall file a timely election under section 754 of the Code and the Income Tax Regulations thereunder to adjust the basis of the Company’s assets under section 734(b) or 743(b) of the Code and a corresponding election under the applicable provisions of state and local law, and the person

34

making such request shall pay all costs incurred by the Company in connection therewith, including reasonable attorneys’ and accountants’ fees. Other tax elections and decisions relating to Taxes not specifically governed by any other express provision of this Agreement shall be made as agreed by the Board of Directors.

9.6 TAX MATTERS PARTNER.

(a) The Initial Phillips Member shall be the Company’s “tax matters partner” for purposes of subchapter C of chapter 63 of subtitle F of the Code (dealing with the tax treatment of partnership items); provided, however, that the tax matters partner shall not take any action without the approval of the Board of Directors or its designee; and provided, further, that the tax matters partner shall receive no compensation for its services as tax matters partner but shall be reimbursed for any out-of-pocket expenses incurred in acting in such capacity.

(b) The Company shall indemnify the tax matters partner (including the officers and directors of a corporate tax matters partner) against judgments, fines, amounts paid in settlement, and expenses (including attorney fees) reasonably incurred in any civil, criminal, or investigative proceeding in which they are involved or threatened to be involved by reason of being the tax matters partner unless the tax matters partner acted in bad faith or with gross negligence. The indemnification provided hereunder shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any applicable statute, agreement, vote of Partners, or otherwise.

ARTICLE 10

RESTRICTIONS ON TRANSFER

10.1 TRANSFER OF INTERESTS. No Member may sell, assign, transfer or hypothecate (“Transfer”) all or any part of its Membership Interest in the Company, or any interest therein, except in accordance with the terms and conditions set forth in this Article 10.

10.6 PERMITTED TRANSFERS SUBJECT TO RIGHT OF FIRST REFUSAL.

(a) At any time after the three (3) year anniversary of the Closing Date, the Class C Member(s) or the Class P Member(s) (a “Transferring Class”) may Transfer not less than all of their respective Class Membership Interest to a Person for cash, subject to the Right of First Refusal provided for in this Section 10.6 and the last sentence of Section 10.2.

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

36

offer. The Transfer Notice shall (i) specify the purchase price for and other material terms with respect to the sale of the Transferred Interest, (ii) identify the proposed purchaser of the Transferred Interest, (iii) specify the date scheduled for the transfer (which date shall not be earlier than one hundred twenty (120) days from the date the Transfer Notice is delivered), (iv) contain a statement that the offer has been accepted pending compliance with the right of first refusal set forth herein and receipt of required regulatory and other approvals, and (v) shall have attached thereto a copy of the written offer containing all of the terms and conditions on which the Transferred Interest is to be sold.

(c) The Non-Transferring Class shall have the exclusive option to purchase all (but not less than all) of the Transferred Interest on terms and conditions substantially the same in all material respects as, and at the same price, set forth in the written offer delivered pursuant to subsection (b) above. The Non-Transferring Class shall notify the Company and the Transferring Class of its intention to exercise or not to exercise the right of first refusal hereunder within forty-five (45) days of receipt by the Non-Transferring Class of a Transfer Notice.

(d) In the event that the Non-Transferring Class shall have duly elected to purchase the Transferred Interest (the “Electing Class”), the Electing Class and the Transferring Class shall diligently pursue obtaining all regulatory approvals and use best commercially reasonable efforts to consummate the closing of the purchase of the Transferred Interest as soon as practicable and in any event within one year from receipt of the Transfer Notice; provided that, if such closing does not occur within such one-year period due to the failure to obtain any required regulatory approvals, the Electing Class’s right to close such sale may be extended at the option of the Electing Class, until such regulatory approvals are obtained, but in no event for a period of greater than one additional year. In the event of a failure of the Non-Transferring Class to elect to purchase all of the Transferred Interest or a failure of the Electing Class to consummate such purchase in accordance herewith, the Transferring Class will be free, at any time within 120 days from the date the Non-Transferring Class elect not to exercise their purchase rights hereunder or from the date the time periods specified in this section for such election have expired, subject, in each case, to extension for up to an additional eight (8) months to the extent necessary to achieve any required regulatory approvals, to consummate the sale of the Transferred Interest to the purchaser at a price and upon terms and conditions no more favorable to the purchaser than those specified in the Transfer Notice; provided that the purchaser shall assume all of the liabilities and obligations of the Transferring Class under this Agreement by a binding written instrument which shall be enforceable by the Company and the Non-Transferring Class.

(e) A Transferring Class shall not be relieved of any of its obligations arising under this Agreement prior to such Transfer. The Transferring Class and any transferee shall execute such documents as the Non-Transferring Class shall reasonably request to evidence the Transfer and the assumption and continuing obligations under this Agreement.

Notwithstanding anything contained herein to the contrary, any Member may Transfer all or any portion of its Membership Interest to a Wholly-Owned Affiliate of such Member, and such Transfer shall be deemed automatically approved by the Board of Directors; provided, however, that such Transfer otherwise meets the conditions and requirements of Sections 10.2 and 10.3.

10.8 TRANSFERS OF EQUITY INTERESTS IN A MEMBER. A sale, assignment, transfer or hypothecation of any direct or indirect equity interest in a Member by a Parent of such Member shall be deemed to be a Transfer by that Member of its Membership Interest in the Company for purposes of this Article 10 and shall not be permitted except in accordance with the terms and conditions set forth in this Article 10. ChevronTexaco and Phillips shall comply with this Section 10.8 and shall take all necessary action to cause their Affiliates to comply with this Section 10.8. For the purpose of clarification of this Section 10.8, a change of control of the Ultimate Parent of any Member shall not be considered a Transfer of such Member’s Membership Interest or a Transfer of the equity interest in such Member.

38

ARTICLE 11

COMPETITION

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

11.2 RESOLUTION OF COMPETITIVE CONFLICTS.

(a) In the event that:

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

(ii) The Non-Competing Class and Competing Class are unable to resolve the conflicts of interest within 150 days of the delivery of the Conflict Notice; and

(iii) The value (in the opinion of a nationally recognized investment bank selected by the Board of Directors) of the Competing Class’s (including its Affiliates’) interests in businesses competing with the businesses of the Company exceeds 50% of the enterprise value of the Company;

then, in such case, the Non-Competing Class shall have the right, within 30 days from the later of (x) the expiration of the period in (ii) above or (y) the determination in (iii) above, to state a single cash price at which it is prepared to purchase the Class Membership Interest of the Competing Class, which will constitute a binding offer to purchase (the “Initial Offer”). In the event of an Initial Offer, the Competing Class shall have 60 days to decide either to accept the Initial Offer or to make a counter-offer by stating a single cash price, which is at least 5% higher than the Initial Offer, at which it is prepared to purchase the Class Membership Interest of the Non-Competing Class (a “Counter-Offer”). In the event of a Counter-Offer, the Non-Competing Class shall have 30 days to decide either to accept the Counter-Offer or to make another offer by stating a single cash price, which is at least 5% higher than the Counter-Offer, at which it is prepared to purchase the Class Membership Interest of the Competing Class (a “Subsequent Offer”). In the event of a Subsequent Offer by the Non-Competing Class, the Competing Class shall have 30 days to decide either to accept the Subsequent Offer or to make another counter-offer by stating a single cash price, which is at least 5% higher than the Subsequent Offer, at which it is prepared to purchase the Class Membership Interest of the Non-Competing Class. The offering process described in this paragraph shall continue in this manner until a price is reached

39

at which either the Competing Class or the Non-Competing Class is willing to sell its Class Membership Interest to the other class. Notwithstanding anything to the contrary in the foregoing, a Member may also sell its Class Membership Interest pursuant to the right of first refusal provisions set forth in Section 10.6.

(b) In the event that a Non-Competing Class has concluded in good faith that the Company is no longer the primary vehicle by which a Competing Class is engaged in the Chemicals Business in accordance with Section 11.1, and:

(i) a sale pursuant to subsection (a) above is not concluded (whether or not the condition expressed in subsection (a)(iii) above is satisfied); and

(ii) the Competing Class and Non-Competing Class have not been able to resolve, pursuant to Section 11.1 above, all substantial conflicts of interest resulting from the ownership by the Competing Class of a substantial business competing with the businesses of the Company;

then either the Competing Class or the Non-Competing Class may require the other class from time to time to enter into good faith negotiations to cause the Company (and/or the Members) to adopt such reasonable, mutually acceptable provisions as would mitigate the potential adverse consequences of the conflicts of interests on the continuing businesses of the Company. Such provisions could include, for example, restrictions on the dissemination and use of confidential information, greater delegation of authority to management of the Company, or modification of minimum distribution requirements or the non-involvement of the Competing Class in business decisions of the Company potentially affecting such competing businesses.

If any excess funds remain in such reserves at the end of such reasonable time, then such remaining funds shall be distributed by the Company to the Members pursuant to Section 12.6 hereof.

INDEMNIFICATION

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

42

not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company, and that, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful.

13.2 INDEMNIFICATION: PROCEEDING BY COMPANY.

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

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

(c) With respect to indemnification pursuant to subsection (a) or (b) above, such indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the Company or for amounts paid in settlement to the Company, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

13.3 MANDATORY ADVANCEMENT OF EXPENSES. The expenses of Directors, Members and officers incurred in defending a civil or criminal action, suit or proceeding must be paid by the Company as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf of the Director, Member or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by the Company. The provisions of this Section 13.3 do not affect any rights to advancement of expenses to which personnel of the Company other than Directors, Members or officers may be entitled under any contract or otherwise.

43

(b) Continues for a person who has ceased to be a Member, Director, officer, employee or agent and inures to the benefit of his heirs, executors and administrators.

(c) In the absence of fraud:

(i) The decision of the Company as to the propriety of the terms and conditions of any insurance or other financial arrangement made pursuant to this Section 13.5 and the choice of the person to provide the insurance or other financial arrangement is conclusive; and

(ii) The insurance or other financial arrangement:

(A) Is not void or voidable; and

(B) Does not subject any Director or Member approving it to personal liability for his action, even if a Director or Member approving the insurance or other financial arrangement is a beneficiary of the insurance or other financial arrangement.

Any indemnification of, or advancement of expenses to, a Director, Member or officer in accordance with this Article 13, if arising out of a proceeding by or on behalf of the Company, shall be reported in writing to the Members with or before the notice of the next Members’ meeting.
