Excess Costs incurred by PPG will be considered as incurred by PPG for its own account or, if not allowed as a loss, contributed to the Company by PPG and, in any event, shall not be considered as amounts paid to or for the benefit of Vista in the formation of the Company and shall not impact the Sharing Ratio.

(B) PPG will contribute to the Company within one hundred twenty (120) days of execution of this Agreement, pursuant to a special warranty deed, the Land.

4.04 Additional Capital. The Committee may determine from time to time that the Company requires additional capital.

(B) In addition, if a Member makes its capital contribution but does not pay any contribution amount for the Non-Contributing Member or its contribution amount is less than all of the unpaid capital contribution of the Non-Contributing Member, then the Company shall set-off against any distributions (on a cash cost basis) or allocation payable to the Non-Contributing Member an amount equal to the amount of the capital contribution not paid by the Non-Contributing Member (after giving effect to any partial payment of such amount by the Contributing Member) together with interest at the prime rate as quoted by The Chase Manhattan Bank, N.A. from the date such amount was due.

(C) Each Member hereby acknowledges that (1) the Members are accepting their obligations under this Agreement in reliance upon the several commitments and obligations of the Members hereunder, and (2) the Members’ satisfaction of such commitments and obligations is the basis for determining each Member’s Sharing Ratio in the Company.

ARTICLE X

TAX & FINANCIAL ACCOUNTING MATTERS

10.01 Tax Characterization, Tax Elections and Tax Returns.

(A) The Members intend and acknowledge that the Company does not have a majority of corporate characteristics and therefore will be classified under §7701 of the Code as a “partnership” for Federal and Louisiana state income tax purposes and not as an association taxable as a corporation. All provisions of the Articles of Organization and this Agreement are to be construed so as to preserve partnership classification and to avoid classification as an association taxable as a corporation.

(B) With Respect To Tax Election:

(1) Pursuant to Code §761(a) and Treasury Reg. §1.761-2, each Member will, and hereby does, elect to exclude the Company from the provisions of Subchapter K of the Code (the “Section 761 Election”). If for any reason the Section 761 Election is revoked or disallowed, the Company will be operated as a partnership for federal and state income tax purposes and the partnership provision of Article X contained in Exhibit B will be effective for the Company.

(2) the Members shall submit to the Internal Revenue Service a request for a ruling: (i) that the Section 761 Election is effective, (ii) that §1031 of the Code shall apply to the formation of the Company and neither Member will recognize gain or loss on the transfer of cash or property to the Company and (iii) that §197(f) (2) of the Code shall apply so that no Member will be deemed to acquire any Section 197 Asset except to the extent, if any, of the adjusted basis of Section 197 Assets in the hands of an exchanging Member. If the Company and its Members do not receive a favorable ruling on their request before the due date (including extensions) of the initial U.S. partnership return for the Company, the Members shall revoke or otherwise abandon the Section 761 Election. In the event such ruling is received before such date, Exhibit B shall not apply to Company operations.

10.02 Financial Accounting for the Company as Required by the Members.

The Company will establish books of account for the Company and will prepare such financial reports and statements as directed by the Members. Such books of account and financial statements shall reflect the investment of the Members in the Company and shall account for all Fixed Costs and Variable Costs of the Company as contemplated by this Agreement.

10.03 Allocations of Expenses and Costs to Members.

(A) Except as otherwise provided, expenses and costs of the Company shall be determined and charged to the Members in accordance with the Budgets authorized by the Members. Subject to the provisions of this Section 10.03, any item of income, gain, loss or expense of the Company shall be shared by the Members in accordance with each Member’s respective Sharing Ratio in effect at the time the item is accrued for financial statement purposes.

(B) Each Member will undertake to account for its proportionate share of the assets, liabilities or expenses of the Company in a manner consistent with this Agreement and with any rulings received from the United States Treasury Department. Should a

Member determine to report its investment or participation in the Company in a manner inconsistent with any tax ruling or this Agreement, such Member will notify the other Members.

10.04 Allocation for Federal Income Tax Purposes.

The Members acknowledge and agree that for federal and state income tax purposes each Member will be treated as owning an undivided interest in each asset or liability of the Company in accordance with the Sharing Ratio. The basis of each Member in such assets will reflect the federal income tax basis of the property contributed to the Company and the amount of any increase or decrease in the basis of each Member’s investment in the Company as determined for federal income tax purposes.

10.05 Tax Matters.

(A) The Operator is designated as the Tax and Financial Accounting Matters Member (“Accounting Member”). The Accounting Member and the other Members shall use their best efforts to comply with responsibilities outlined in this Section and in the Code and in doing so shall incur no liability to any other Member. Notwithstanding the Accounting Member’s obligation to use its best efforts in the fulfillment of its responsibilities, the Accounting Member shall not be required to incur any expenses for the preparation for or pursuance of administrative or judicial proceedings, unless the Members agree on a method for sharing such expenses.

(B) The Accounting Member shall prepare and file all required federal, state, and local Company tax returns, including all sales, use and other excise tax returns. In preparing such returns the Accounting Member shall use its best efforts and in doing so shall incur no liability to any other Member with regard to such returns. Upon the request of any Member, the Accounting Member shall submit to such Member a copy of the tax returns for review.

(C) The Accounting Member shall keep all Members informed of any significant administrative or judicial proceedings involving the Company.

(D) Any Member intending to commence any judicial action with respect to any Company item or to other tax matters involving the Company, shall notify the other Member, prior to such filing, of the nature of the contemplated proceeding. In the case where the Accounting Member is the Member intending to file or commence such action, such notice shall be given within a reasonable time to allow the other Members to

participate in the choosing of the forum in which such action will be filed if the action has any material direct or indirect consequences to the other Members. If the Members do not agree on the appropriate forum, the Accounting Member shall choose the forum. If a Member intends to seek review of any court decision rendered as a result of such a proceeding, such Member shall notify the other Member prior to seeking such review.

10.06 Transfers.

Transfers of a Member’s ownership interest in the Company shall be governed by this Agreement. A Member transferring its interest, or any part thereof, shall notify the Accounting Member in writing within two weeks of such transfer.

RIGHT OF FIRST REFUSAL; SALE/PURCHASE OPTION

12.01 Right of First Refusal.

(A) No Member shall sell any or all of its ownership interest in the Company until five (5) years after the Start-Up Date. If a Member who is not in default under this Agreement (the “Seller”) shall receive a bona fide written offer on or after the fifth (5th) anniversary of the Start-Up Date from a Person other than an Affiliate of the Seller (the “Third Person”) for the purchase of any or all of the Seller’s interest in the Company (the “Seller’s Interest”) at a price and under terms and conditions acceptable to the Seller, then the Seller shall (1) notify the other Member (the “Non-Selling Member”) and the Company of the Third Person’s offer, setting forth in reasonable detail the terms and conditions of the offer and identifying the Third Person, its principals and affiliates (the “Seller’s Notice”); and (2) give a right of first refusal to the Non-Selling Member to purchase the Seller’s Interest on the same terms and conditions as are set forth in the Third Person’s offer.

(B) Except as otherwise provided in Section 12.01(C), the Non-Selling Member shall respond in writing to the Seller’s Notice within thirty (30) days of receipt stating whether it wishes to exercise its right of first refusal. If the Non-Selling Member does not respond to the Seller’s Notice within such thirty (30) day period, then the Non-Selling Member shall be conclusively presumed to have chosen not to exercise its right of first refusal and the Seller may proceed with the sale of the Seller’s Interest to the Third Person pursuant to the terms set forth in the Seller’s Notice.

(C) f the Non-Selling Member elects to exercise its right of first refusal and so notifies the Seller pursuant to Section 12.01(B), then such Non-Selling Member shall purchase and the Seller shall sell the Seller’s Interest pursuant to the terms and conditions set forth in the Seller’s Notice. The closing of such sale shall be held at a time and place to be determined by the Parties; provided, however, that the closing must occur by the later of the date of closing specified in the Seller’s Notice or ninety (90) days after the Non-Selling Member gives notice of its election to purchase the Seller’s Interest; and provided further, that the closing shall be subject to any delay caused by the (1) failure of the Seller, the Non-Selling Member or the Company to obtain, despite their mutual reasonable efforts, all

necessary consents and approvals; or (2) existence of any injunctive or other action undertaken by any Person which may prevent the consummation of such purchase.

(D) If the Third Person’s offer provides for consideration other than cash or an obligation to pay cash in the future (“Unique Consideration”), the Seller and Non-Selling Member shall agree to an amount of cash in lieu of the Unique Consideration within thirty (30) days of the date of the Seller’s Notice. If the Non-Selling Member and the Seller cannot reach an agreement in regard to the cash value of the Unique Consideration within such period, then the Seller and Non-Selling Member shall each select a qualified appraiser. The appraisers shall each report in writing the results of their appraisals of the Unique Consideration within sixty (60) days of Seller’s Notice. The cash value of the Unique Consideration shall be the average of the cash value assigned to the Unique Consideration by the appraisers. The fees of each of the appraisers shall be borne by the party by whom they were retained. Within ten (10) days of receipt of the cash valuation of the Unique Consideration as determined pursuant to this Section 12.01(D), the Non-Selling Member may notify the Seller in writing that it no longer wishes to purchase the Seller’s Interest and, in such an event the Non-Selling Member will have no further obligation to the Seller, and the Seller may proceed with the sale of the Seller’s Interest to the Third Party pursuant to the terms of the Seller’s Notice.

(E) During any periods of negotiation between Seller and either the Non-Selling Member or a Third Person, Sections 12.02 and 12.03 are suspended and may not be invoked by either Member.

(F) Upon the closing of the sale of the Seller’s Interest to the Third Person pursuant to the terms of the Seller’s Notice, the Third Person shall become a Member of the Company and shall execute a duplicate of this Agreement, and certain Ancillary Agreements, in each case as earlier amended to reflect the inclusion of the new Member, and shall have all of the rights and obligations of a Member herein and therein. No sale of the Seller’s Interest shall relieve Seller of its obligations under Article XIV.

12.02 Good Faith Negotiations. Beginning five (5) years after the Start-Up Date, either Member (the “Initiating Member”) may offer, in writing, to enter into good faith negotiations with the other Member (the “Receiving Member”) for the sale of the Initiating Member’s full or partial share of the Company. Upon receipt of such an offer, the Receiving Member shall enter into good faith negotiations with the Initiating Member for a period of not less than ninety (90) days. If the Members are unable to reach an agreement within this period, the Initiating Member shall be free to sell for a period of ninety (90) days after the negotiating period to a third Person. During the ninety (90) day

good faith negotiating period and for ninety (90) days thereafter, Sections 12.01 and 12.03 shall be suspended. Such sale to the third Person shall be for the same ownership percentage offered to the Receiving Member at a price and under terms and conditions no less favorable than were offered to the Receiving Member. If the Initiating Member enters into a letter of intent with a third Person within ninety (90) days after the negotiating period, Sections 12.01 and 12.03 will remain suspended for an additional one hundred eighty (180) days to allow completion of any sale of interest.

12.03 Option.

(A) At any time after the fifth (5th) anniversary of the Start-Up Date, each Member shall have the option to purchase all of the other Member’s ownership interest in the Company by submitting an offer (“Offer”) to the other Member. Within ninety (90) days after the date of the Offer, the other Member (the “Non-Offering Member”) shall either (1) agree to sell the Non-Offering Member’s ownership interest in the Company to the Offering Member pursuant to the terms and conditions of the Offer; or (2) agree to purchase the Offering Member’s ownership interest in the Company pursuant to equivalent terms and conditions as set forth in the Offer.

(B) The closing date of the above-described transaction shall be within ninety (90) days of the date the Offer was made (the “Option Closing Date”) provided, however, that the closing shall be subject to any delay caused by the (1) failure of the Members or the Company to obtain, despite reasonable efforts, all necessary consents and approvals; or (2) existence of any injunctive or other action undertaken by any Governmental Authority which may prevent the consummation of such transaction. During any negotiations under this Section, Sections 12.01 and 12.02 are suspended and may not be invoked by either party.

12.04 Exceptions. Nothing set forth in Sections 12.01, 12.02, or 12.03 shall prohibit the following from taking place at any time:

(A) PPG shall be permitted to sell substantially all of the PPG Chemicals Complex including, without limitation, PPG’s ownership interest in the Company;

The mediation or arbitration shall compare the action, inaction, policy or procedure which gave rise to the finding of liability under Sections 14.01(D) and/or (F) to the common practices in the VCM manufacturing business including, but not limited to, Vista’s VCM manufacturing facilities and, if there is a determination of liability under Section 14.01(F)against the Company, shall determine whether such finding is based on or attributable to the PPG Parties gross negligence; willful misconduct; wanton or reckless disregard for public safety; or intentional acts or omissions, the harmful consequences of which were intended, consciously desired, or were known to be substantially certain to follow from those acts or omissions. If the action, inaction, policy or procedure which was the basis for the finding of liability under Section 14.01(D) or (F) was in conformity with the common practices in the VCM manufacturing business or was not attributable to PPG as set forth above, then PPG shall have no obligation under Section 14.01(D) or (F).

In addition, PPG shall have no liability under Section 14.01(D) or (F) if the action, inaction, policy or procedure which resulted in liability under Section 14.01(D) or (F) had been approved by the Committee. Furthermore, PPG shall not have liability under Section 14.01(D) or (F) to the extent such liability under Section 14.01(D) or (F) was contributed to by the Vista Indemnified Parties.

To the extent indemnities are provided pursuant to this Section 14.01 and, except for procedures allowed under Article XIII, PPG shall not have a right of recovery against the Company or the Vista Indemnified Parties in connection with the event or act which is the subject of the indemnity.

14.02 Environmental.

(A) PPG acknowledges that pollution or contamination exists on the Lake Charles Complex which are attributable to operations prior to the Closing Date of this Agreement and that contamination will continue to exist as of the Commissioning Date. For the purposes of indemnification and apportionment of environmental liabilities among PPG, the Company and the Vista Indemnified Parties after the Commissioning Date, it shall be presumed that any pollution or contamination found on the Company’s Property after the Commissioning Date is attributable to operations prior to the Commissioning Date and is thereby covered by PPG’s Indemnity contained in Section 14.01, unless PPG can clearly demonstrate that the pollution or contamination had not occurred as of the Commissioning Date or is attributable to a specific operation or event that occurred after the Commissioning Date at the Expanded VCM Plant.

(B) To minimize the potential for contamination from operations of the Expanded VCM Plant, PPG shall modify or replace the following Existing VCM Plant facilities and equipment prior to the Commissioning Date:

(1) the sewer system in accordance with plans and specifications previously approved as PPG Project No. P-4593; and

(2) Furnace Feed Tanks 1, 2, and 3; DH Bottoms Tanks 1, 2, and 3; Crude EDC Tanks 1, 2 and 3; and DH Feed Tank to provide for leak detection and collection.

If PPG fails to complete the modification(s) or replacement(s) of the above specified facilities prior to the Commissioning Date, PPG shall retain all liabilities and costs associated with their operation, modification or replacement between the Commissioning Date and the date the modification(s) or replacement(s) are completed. PPG shall provide Vista with an opportunity to review and comment on the engineering reports, plans and specifications prior to commencing construction of the modification(s) or replacement(s).

(C) PPG acknowledges that the following Existing VCM Plant facilities are designated “solid waste management units” under Hazardous Waste Permit No. LAD008086506 and are subject to corrective action requirements under the Hazardous and Solid Waste Amendments of 1984 to the Resource Conservation and Recovery Act of 1976: the VCM II Separator Site and the BAT (“Best Available Technology”) Metals Removal Sump Site. If required by Law, PPG shall assume all costs of closure, post-closure care, replacement, modification, investigation, and remediation of the above-described facilities before or after the Commissioning Date.

(D) Subject to the presumption stated in Section 14.02(A) hereof, the Company shall assume liability for costs associated with investigating and remediating pollution or contamination attributable to the Company’s operations after the Commissioning Date, unless such pollution or contamination is caused by acts, omissions or operations of PPG Parties occurring or located off the Company’s Property but within the PPG Chemicals Complex; provided that, the Company shall only be liable for the costs of investigating and remediating such pollution or contamination which exceed the costs that are incurred investigating and remediating pollution or contamination attributable to operations occurring prior to the Commissioning Date.

14.03 Toxic Tort/Product Liability Claims. PPG will indemnify, defend and hold harmless the Company and the Vista Indemnified Parties from and against all Claims arising from employment with PPG or its Affiliates for personal injury caused by or alleged to have resulted from exposure to chemicals (including, without limitation, toxic tort Claims), or based on product liability, which are brought by or on behalf of:

(A) Former Employees; or

(B) Current Employees at the PPG Chemicals Complex who have not performed services at the Expanded VCM Plant provided, however, that this Section 14.03(B) shall not apply to Claims of such Current Employees for personal injury or product liability for acute health effects to such Current Employees which are attributable to specific operations or events that occur at the Expanded VCM Plant after the Commissioning Date; or

(C) Current Employees at the Expanded VCM Plant who performed services for PPG Parties prior to January 1, 1982, including Claims based on or alleged to be based on the sole and/or concurrent negligence of the Company and/or the Vista Indemnified Parties; provided, however, that this Section 14.03(C) shall not apply to Claims for personal injury or product liability for acute health effects to Current Employees at the

Expanded VCM Plant which are attributable to specific operations or events that occur at the Expanded VCM Plant after the Commissioning Date; or

(D) Current Employees at the Expanded VCM Plant who have performed services for PPG Parties at facilities other than the Expanded VCM Plant; provided, however, that the indemnities provided pursuant to this Section 14.03(D) shall not apply to Claims by Current Employees at the Expanded VCM Plant for personal injury and/or product liability for acute health effects which are attributable to a specific operation or event that occurs at the Expanded VCM Plant after the Commissioning Date; provided, however, that the indemnities provided in this Section 14.03(D) shall be offset by a reimbursement to be made by the Company to PPG for the Company’s proportional share of the costs of defense, settlement or judgment in connection with the Claims according to a ratio, the numerator of which is the total time the Current Employees’ time has been charged to the Expanded VCM Plant’s operations and the denominator of which is the total length of time the Current Employee has been employed by the Company, PPG or its Affiliates, in each case as of the date that the last incident or exposure giving rise to the Claim occurred.

It is intended that, to the extent indemnities are provided pursuant to this Section 14.03, PPG shall not have a right of recovery against the Company or the Vista Indemnified Parties in connection with the event or act which is the subject of the indemnity.

14.04 Vista’s Indemnity. Except as provided in Sections 14.01 through 14.03, Vista will indemnify, defend and hold harmless the Company and the PPG Indemnified Parties from and against any and all Claims arising on or after the Commissioning Date whether for property damages, personal injury, governmental fines or penalties (including, without limitation, for the violation of operating permits), environmental or natural resources damages or liabilities (including remedial liabilities), exemplary or punitive damages or otherwise to the extent such Claims arise out of, result from or are attributable to:

(A) any representation or warranty of Vista contained herein which was false when made;

(B) the willful breach of any covenant or other promise of Vista contained herein;

(C) Vista Parties’ gross negligence; willful misconduct; wanton or reckless disregard for public safety; or intentional acts or omissions, the harmful consequences of which were intended, consciously desired, or were known to be substantially certain to follow from those acts or omissions; or

(D) the transportation, sale, exchange or use of VCM distributed to Vista by the Company after the Point of Delivery; provided, however, that the indemnities provided in this Section 14.04 (D) shall apply to Claims arising out of, resulting from or attributable to transportation of VCM prior to the Point of Delivery in the event such claims are attributable to railcar failure due to structural defects, system failure, improper railcar maintenance, or failure to comply to standards applicable to railcars transporting VCM.

The indemnities provided in this Section 14.04 shall survive dissolution of the Company, any successor thereto, and termination of this Agreement Any determination of Vista’s liability under Section 14.04(C), as determined by a court of competent jurisdiction after all appeals have been exhausted, shall be reviewed pursuant to Article XIII, in order to determine whether the damages based on Vista’s liability under Section 14.04(C) should be treated as such liability for the purposes of this Agreement. The mediation or arbitration shall compare the action, inaction, policy or procedure which gave rise to the finding of liability under Section 14.04(C) to the common practices in the VCM manufacturing business including, but not limited to, Vista’s VCM manufacturing facilities. If the action, inaction, policy or procedure which was the basis for the finding of liability under Section 14.04(C)was in conformity with the common practices in the VCM manufacturing business, then Vista shall have no obligation under Section 14.04(C).

In addition, Vista shall have no liability under Sections 14.04(C) and (D) if the action, inaction, policy or procedure which resulted in liability under Sections 14.04(C) and (D) had been approved by the Committee. Furthermore, Vista shall have not have liability under Section 14.04(C) and (D) to the extent such liability under Section 14.04(C) and (D) was contributed to by PPG Indemnified Parties.

To the extent indemnities are provided pursuant to this Section 14.04 and except for the procedures allowed under Article XIII, Vista shall not have a right of recovery against the Company or the PPG Indemnified Parties in connection with the event or act which is the subject of the indemnity.

14.05 The Company’s Indemnity. Except as provided in Sections 14.01 through 14.04, the Company will indemnify, defend and hold harmless the PPG Indemnified Parties and the Vista Indemnified Parties from and against any and all Claims arising on or after the Commissioning Date whether for property damages, personal injury, governmental fines or penalties (including, without limitation, for the violation of operating permits), environmental or natural resources damages or liabilities (including remedial liabilities), or otherwise relating to the operation of the Company to the extent such Claims arise out of, result from or are attributable to:

(A) Vista Parties’ sole and/or concurrent negligence, or strict liability;

(B) PPG Parties’ sole and/or concurrent negligence, or strict liability; or

To the extent indemnities are provided pursuant to this Section 14.05, it is intended that the Company shall not have a right of recovery against the PPG Indemnified Parties or the Vista Indemnified Parties in connection with the event or act which is the subject of the indemnity. Additionally, it is intended that the indemnities provided in this Section 14.05 shall address all liabilities not otherwise addressed pursuant to this Article XIV.

14.06 Indemnification of Management

(A) Subject to Section 14.06(C), the Company shall indemnify any person who is or was 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 (other than an action by or in the right of the Company) by reason of the fact that he is or was a member of the Committee or director, officer, employee or agent of the Company; or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise; against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner 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 shall 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, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

(B) Subject to Section 14.06(C), the Company shall indemnify any person who is or was 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 member of the Committee or a director, officer, employee or agent of the Company; or is or was a director or officer of the Company serving at the request of the Company as a director, officer employee or agent of another company,

partnership, joint venture, trust, employee benefit plan or other enterprise; against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Company; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged liable to the Company unless, and only to the extent that, a court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

(C) Any indemnification under this Section 14.06 (unless ordered by a court) shall be made by the Company only as authorized in the specific case upon a determination that indemnification of the members of the Committee, director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 14.06(A) or Section 14.06(B), as the case may be. Such determination shall be made by the voting members of the Committee by a unanimous vote of voting members who were not parties to such action, suit or proceeding; or if such a vote is not obtainable or, even if obtainable the disinterested voting members so direct, by independent legal counsel in a written opinion. To the extent, however, that a member of the Committee, a director, officer, employee or agent of the Company has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith, without the necessity of authorization in the specific case.

(D) For purposes of any determination under Section 14.06(C), a person shall be deemed to have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, or with respect to any criminal action or proceeding, to not have had reasonable cause to believe his conduct was unlawful, if his action is based on the records or books of account of the Company, or on information supplied to him by the officers of the Company in the course of their duties, or on the advice of legal counsel for the Company, by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Company. The provisions of this Section 14.06(D) shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Sections 14.06(A) or 14.06(B), as the case may be.

(E) Notwithstanding any contrary determination in the specific case under Section 14.06(C), and notwithstanding the absence of any determination thereunder, any member of the Committee, any director, officer, employee, agent or servant may apply to any court of competent jurisdiction in the State of Louisiana for indemnification to the extent otherwise permissible under Sections 14.06(A) and 14.06(B). The basis of such indemnification by a court shall be a determination by such court that indemnification of the member of the Committee, director, officer, employee, agent or servant is proper in the circumstances because he has met the applicable standards of conduct set fort in Sections 14.06(A) or 14.06(B), as the case may be. Neither a contrary determination in the specific case under Section 14.06(C) nor the absence of any determination thereunder shall be a defense to such an application or create a presumption that the member of the Committee, director, officer, employee, agent or servant seeking indemnification has not met any applicable standard of conduct. Notice of any application for indemnification pursuant to this Section 14.06(E) shall be given to the Company promptly upon the filing of such application. If successful, in whole or in part, the member of the Committee director, officer, employee, agent or servant seeking indemnification shall also be entitled to be paid the expense of prosecuting such application.

(F) Expenses incurred by a member of the Committee, director, officer, employee, agent or servant in defending or investigating a threatened or pending action, suit or proceeding may be paid by the Company in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such member of the Committee, director, officer, employee, agent or servant to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Company as authorized in this Section 14.06.

(G) The indemnification and advancement of expenses provided by or granted pursuant to this Section 14.06 shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any other agreement, or pursuant to the direction (howsoever embodied) of any court of competent jurisdiction or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, it being the policy of the Company that indemnification of the persons specified in Sections 14.06(A) and 14.06(B) shall be made to the fullest extent permitted by law. The provisions of this Section 14.06 shall not be deemed to preclude the indemnification of any person who is not specified in Section 14.06(A) or 14.06(B) but whom the Company has the power or obligation to indemnify under the provisions of the laws of the State of Louisiana, or otherwise.

(H) The Company may purchase and maintain insurance on behalf of any person who is or was a member of the Committee, director, officer, employee, agent or servant of the Company, or is or was a member of the Committee, director or officer of a company serving at the request of the Company as a director, officer, employee, agent or servant of another company, partnership, joint venture, trust, employee benefit plan or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Company would have the power or the obligation to indemnify him against such liability under the provisions of this Section 14.06.

(I) For purposes of this Section 14.06, references to “the Company” shall include, in addition to the resulting Company, any constituent company (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify the members of its Committee, directors, officers, employees, agents or servants, so that any person who is or was a member of its Committee, director, officer, employee, agent or servant of such constituent company, or is or was a director or officer of such constituent company serving at the request of such constituent company as a director, officer, employee, agent or servant of another company, partnership, joint venture, trust, employee benefit plan or other enterprise, shall stand in the same position under the provisions of this Article XIV with respect to the resulting or surviving company as he would have with respect to such constituent company if its separate existence had continued. For purposes of this Section 14.06, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Company” shall include any service as a member of the Committee, director, officer, employee, agent or servant of the Company which imposes duties on, or involves services by, such member of the Committee, director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Section 14.06.

(J) The indemnification and advancement of expenses provided by, or granted pursuant to, this Section 14.06 shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a member of the Committee, director, officer, employee, agent or servant and shall inure to the benefit of the heirs, executors and administrators of such a person.

(K) Notwithstanding anything contained in this Section 14.06 to the contrary, except for proceedings to enforce rights to indemnification (which shall be governed by

Section 14.06(E) hereof), the Company shall not be obligated to indemnify any member of the Committee, director, officer, employee, agent or servant in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Committee.

14.07 Miscellaneous. Except as provided under Section 14.03, where liability is adjudged by a court of competent jurisdiction against the Company and one or more of the Members and the court does not allocate liability among the parties, the parties shall allocate liability based upon a review of all factors specific to that Claim including, without limitation, (A) the length of time of exposure after the Commissioning Date compared to the length of time exposure is alleged to have occurred prior to the Commissioning Date, (B) the types of chemicals to which the claimant was exposed, and (C) the pre- and post-Commissioning Date levels of exposure. For purposes of allocating liability, the procedures set forth in Article XIII shall be used by the parties. The persons or arbitrators allocating liability pursuant to Article XIII shall allocate such liability consistent with the intent of this Article XIV.

14.08 Damage Limitation. UNLESS OTHERWISE PROVIDED FOR IN THIS ARTICLE XIV, IN NO EVENT SHALL A MEMBER OR THE COMPANY BE LIABLE TO ANOTHER MEMBER OR THE COMPANY, THEIR RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR SERVANTS FOR ANY INCIDENTAL, SPECIAL, INDIRECT, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES INCLUDING, WITHOUT LIMITATION, THOSE WHICH ARE ATTRIBUTABLE TO OR CLAIMED AS A RESULT OF PROPERTY DAMAGE, PERSONAL INJURY, WRONGFUL DEATH AND/OR BREACH OF CONTRACT, EVEN IF SUCH DAMAGES ARE CAUSED BY A MEMBER’S OR THE COMPANY’S WILLFUL CONDUCT, SOLE OR CONCURRENT GROSS NEGLIGENCE, SOLE OR CONCURRENT NEGLIGENCE, OR SOLE OR CONCURRENT NEGLIGENCE PER SE. THIS SECTION SHALL NOT APPLY TO CLAIMS THAT ORIGINATED WITH THIRD PARTIES AGAINST EITHER OF THE MEMBERS OR THE COMPANY.

ARTICLE XV

Prior to the Start-Up Date, PPG shall present to Vista for Vista’s review, forty-five (45) railcars, each in good working order and capable of hauling ninety (90) tons of VCM. Within sixty (60) days of the Start-Up Date, Vista shall have the right to purchase, in Vista’s

sole discretion, any or all of the forty-five (45) railcars presented to Vista. After a railcar is delivered to and accepted by Vista, Vista shall pay PPG Five Thousand Four Hundred Twenty-Two Dollars ($5,422.00) for each railcar so purchased by Vista.

TAX MATTERS

10.01 Tax Characterization and Returns. The Members acknowledge that the Company will be treated as a “partnership” for Federal and Louisiana state income tax purposes. All provisions of the Company’s Articles of Organization and this Agreement are to be construed so as to preserve that status.

10.02 Capital Accounts. The Company will establish a Capital Account for each Member in accordance with Regulation Section 1.704-l(b)(2)(iv) and will maintain each Capital Account according to the following rules:

(A) the Capital Account shall be increased by (1) the amount of the Member’s capital contribution made in cash; (2) the agreed fair market value of assets contributed in kind (net of liabilities that the Company is considered to assume or take subject to); and (3) the amount of income and gain, or items thereof, allocated to the Member pursuant to this Agreement.

(B) the Capital Account shall be decreased by (1) the amount of money and the fair market value of property distributed to each Member (net of liabilities assumed by such Member or to which the property is subject); (2) that Member’s allocated share of Company loss and deduction, or items thereof; and (3) any basis decreases required by the Code.

(C) in accordance with Regulation Sections 1.704-l(b)(2)(iv)(d)(3) and 1.704-l(b)(2)(iv)(g), in the case of property contributed to the Company, the contributing Members’ Capital Accounts shall be increased or decreased for items of depreciation, amortization, gain or loss computed for book purposes with respect to such property in the same manner as such items would be computed if the adjusted tax basis of such property were equal to its fair market value on the date of its contribution to the Company. In accordance with Regulation Section 1.704-l(b)(2)(iv)(g)(iii), the amount of book depreciation or amortization for a period with respect to contributed property shall be the amount that bears the same relationship to the book value of such property as the depreciation or amortization computed for tax purposes with respect to such property for such period bears to the adjusted tax basis of such property provided that, if such property has a zero adjusted tax basis, the book depreciation or amortization shall be determined under any reasonable method selected by the TMP. The fair market value of property contributed to the Company shall be based upon the agreed net fair market value of the property under Article IV hereof.

(D) for purposes of computing and maintaining Capital Accounts pursuant to this Section 10.02, immediately prior to the distribution of any asset of the Company to a Member (including a distribution in liquidation of the Company), the amount of unrealized gain with respect to the asset shall be deemed to be an item of Capital Account income or gain recognized by the Company and shall be allocated to the Members as provided in Section 10.03 of this Agreement, and the amount of unrealized loss with respect to the asset shall be deemed to be an item of Capital Account deduction or loss recognized by the Company and shall be allocated to the Members as provided in Section 10.03 of this Agreement. For this purpose, the unrealized gain with respect to an asset of the Company shall be equal to the excess of the value of the asset over its adjusted book basis of the asset and the unrealized loss with respect to an asset of the Company shall be equal to the excess of the adjusted book basis of the asset over the distribution value of the asset as determined under Section 10.02(B).

(E) a transferee of an interest in the Company shall succeed to the Capital Account attributable to the interest, and there shall be no adjustment to the Capital Account as a result of the transfer provided, however, that if the transfer causes a deemed termination of the Company pursuant to Section 708(b)(1)(b) of the Code, the assets of the Company shall be deemed to have been distributed to the Members (including the transferee) in liquidation of the Company and recontributed by the Members in reconstitution of the Company. The Capital Accounts of the Company following the deemed reconstitution shall be maintained in accordance with the principles of this Section 10.02. In the event the Members cannot reach agreement as to the fair market value of an asset distributed or deemed distributed, the Members will follow the dispute resolution provisions outlined in Article XIII to resolve the difference in opinion on such values.

(F) the Operator shall make all other adjustments to the Capital Accounts required by Regulation Section 1.704-l(b)(2)(iv).

(G) book basis of an asset for the Company shall be the cost to the Company for an asset acquired by purchase or the fair market value of the asset for an asset acquired from a Member in contribution to the Company. Adjusted book basis is book basis with adjustment required under Section 10.02. A Member’s book basis is the Member’s share of book basis which is reflected in the Member’s Capital Account. The tax basis and adjusted tax basis of an asset to the Company are as determined under the Code. A Member’s share of an asset tax basis or adjusted tax basis is the amount of such basis reflected in the Member’s Capital Account maintained using tax basis rather than book basis.

10.03 Allocations.

(A) All expenses and revenues of the Company shall be determined and charged or credited, as the case may be, to the Members in accordance with the provisions of this Section. Subject to the provisions of this Section 10.03, expenditures and revenue of the Company shall be shared by the Members in accordance with each Member’s respective Sharing Ratio.

(B) Allocations for Capital Account purposes shall be resolved as follows:

(1) the Members shall be entitled to their respective Sharing Ratio of the output of the Expanded VCM Plant. If such output is distributed in kind to a Member, adjustments required by Section 10.02(D) shall be made to the Member’s Capital Account receiving such distribution.

(2) except as otherwise provided in this Section 10.03, for purposes of maintaining Capital Accounts pursuant to Section 10.02, (a) each item of income and gain shall be allocated in the same proportion as the corresponding item of income and gain is allocated pursuant to Section 10.04; and (b) each item of deduction or loss shall be allocated in the same proportion as the corresponding item of loss or deduction is allocated pursuant to Section 10.04.

(3) for purposes of computing and maintaining Capital Accounts pursuant to Section 10.02, (a) gain with respect to the disposition of any Company property or asset shall be determined by the Members by subtracting the adjusted book basis of such property or asset from the Member’s Sharing Ratio of the amount realized on such disposition, and (b) loss with respect to the disposition of any Company property or asset shall be determined by the Members by subtracting the Member’s Sharing Ratio of the amount realized on such disposition from the adjusted book basis of such property or asset.

(C) For purposes of computing and maintaining Capital Accounts pursuant to Section 10.02 of this Agreement, each Section 705(a)(2)(B) expenditure of the Company shall be allocated in the same proportion as the cost giving rise to the Section 705(a)(2)(B) expenditure is charged pursuant to Section 10.03(A) above.

10.04 Allocation for Federal Income Tax Purposes.

(A) For federal income tax purposes, except as otherwise provided in Section 10.04, all items of Company income, gain, loss, and deduction with respect to a taxable year of the Company shall be allocated to the Members as follows:

(1) income arising from a sale of raw materials, feedstock, inventory, or products produced by the Company’s operations shall be allocated in accordance with the applicable Member’s contributions to the variable costs of such raw materials, feedstock, inventory or products.

(2) depreciation with respect to investment in the Existing VCM Plant, equipment or facilities contributed by PPG pursuant to Section 4.03 hereof shall be allocated to PPG.

(3) deductions arising from operating expense shall be allocated to the Members in the same manner in which they contributed to the costs of operations under this Agreement.

(4) depreciation with respect to capital improvements and expansion of the VCM Plant, to the extent that such expansion, improvements, or facilities are funded by the contributions of Vista pursuant to Section 4.02 or 4.04, shall be allocated to Vista. One hundred percent (100%) of capital expenditures for additions, improvements, expansions, or acquisition of additional equipment or facilities added to the Existing VCM Plant shall be considered funded by Vista’s contributions until Vista’s contributions under Section 4.02 and 4.04 have been fully expended by the Company and tracing of funds for this purpose shall not be necessary. Any expenditures contributed to the expansion of the VCM Plant by PPG shall be allocated to PPG; provided, however, that if such contribution is a result of a cost over-run in construction of the Expanded VCM Plant, the Members hereby agree such contribution for Capital Account purposes shall be zero.

(5) for purposes of taxable gain or loss of the Members, (a) gain with respect to the disposition of any Company property or asset shall be determined by the Members by subtracting the adjusted tax basis of such property or asset from the Member’s Sharing Ratio of the amount realized on such disposition, and (b) loss with respect to the disposition of any Company property or asset shall be determined by the Members by subtracting the Member’s Sharing Ratio of the amount realized on such disposition from the adjusted tax basis of such property or asset.

(6) deductions or tax expense arising from costs incurred by the Company and charged to the Members under Article V shall be allocated for tax purposes to the Members in the same manner as such costs are charged to the Members under such Article V.

(7) any other item of income or loss shall be allocated in accordance with the Sharing Ratios of the item of revenue or expense, respectively, that gives rise to such item of income or loss.

(B) to the extent of any Recapture Income resulting from the sale or other disposition of an asset of the Company, the amount of any gain from the disposition allocated to (or recognized by) a Member for federal income tax purposes pursuant to the above provisions shall be deemed to be Recapture Income to the extent the Member (or its predecessor in interest) has been allocated or has claimed any deduction directly or indirectly giving rise to the treatment of the gain as Recapture Income.

(C) notwithstanding any other provisions of this Agreement to the contrary, if, with respect to any taxable year of the Company, a Member receives an adjustment, allocation or distribution of the type described in Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6) of the Regulations that results in such Member’s Capital Account having a negative balance, Capital Account gross income (and the corresponding items of income or gain for federal income tax purposes) and the Amount Realized on the disposition of a Company property for that taxable year and all subsequent taxable years shall be allocated to that Member in an amount necessary to eliminate the negative balance in the Member’s Adjusted Capital Account as quickly as possible. The provisions of this Section 10.04 are intended to constitute a “qualified income offset” within the meaning of Section 1.704-l(b)(2)(ii)(d)(3) of the Regulations and shall be construed in accordance with that intention.

(D) beginning in the first taxable year in which there are “nonrecourse deductions” or a distribution is made of proceeds of a nonrecourse liability that are allocable to an increase in the minimum gain of the Company, as determined under the rules of Section 1.704-2(e)(3) of the Regulations, and thereafter throughout the full term of the Company, the “Minimum Gain Chargeback” rules of Section 1.704-2(f) of the Regulations, shall apply with respect to the allocation of all Company items in those year(s). If there is a net decrease during a taxable year of partner nonrecourse debt minimum gain within the meaning of Section 1.704-2(i)(3), then the chargeback rules of Section 1.704-2(i)(4) shall apply.

(E) notwithstanding any of the foregoing provisions of Section 10.04 to the contrary, if during any fiscal year of the Company the allocation of any loss or deduction (net of any income or gain) to a Member (the “Deficit Member”) would cause or increase a negative balance in the Member’s Capital Account as of the end of that fiscal year, only the amount of such loss or deduction that reduces the balance to zero shall be allocated to the Deficit Member and the remaining amount shall be allocated to the Member whose Capital Account has a positive balance remaining at that time.

(F) any special allocations of items of income pursuant to Section 10.04 shall, to the extent consistent with such Section, be taken into account in computing subsequent allocations of deduction and loss, so that the resulting Capital Account balance of each Member shall, to the maximum extent possible consistent with such Section, be equal to the balances that would have existed if such special allocations had not occurred. The preceding sentence shall only be applied before taking into account any gain or deemed gain from the sale or deemed sale of Company properties.

(G) if a Member transfers an interest in the Company during a taxable year, items of Company income, loss, deduction and credit attributable to the transferred interest shall be allocated between the transferor and the transferee pursuant to any agreement between the transferor and transferee which is submitted to the TMP and which is consistent with Section 706 of the Code.

(H) notwithstanding anything to the contrary herein, solely for federal and applicable state income tax purposes, upon the contribution of property in kind to the Company, to the extent required by Section 704(c) of the Code, income, gain, loss and deduction with respect to the contributed property shall be allocated so as to take into account the difference between the fair market value of the property at the time of contribution and its adjusted basis at that time.

10.05 Tax Matters Partner.

(A) The Operator is designated as the Tax Matters Partner (“TMP”), as such term is defined in the Code, and, so long as such Operator remains a Member, shall serve until replaced by action of the Committee. In the event of any change in the TMP, the Member serving as TMP at the beginning of a given taxable year shall continue as TMP with respect to all matters concerning such year. The TMP and the other Member(s) shall use their best efforts to comply with responsibilities outlined in this Section and in the Code (including any Treasury Regulations promulgated thereunder) and in doing so shall incur no liability to any other Member. Notwithstanding the TMP’s obligation to use its best efforts in the

fulfillment of its responsibilities, the TMP shall not be required to incur any expenses for the preparation for, or pursuance of administrative or judicial proceedings, unless the Members agree on a method for sharing such expenses.

(B) The TMP shall prepare and file all required federal, state, and local Company income tax returns, as well as all sales, use and other excise tax returns. In preparing such returns the TMP shall use its best efforts and in doing so shall incur no liability to any other Member with regard to such returns. The TMP shall submit to each Member a copy of the income tax returns as proposed for review (1) not less than thirty (30) days prior to the due date (including extensions) and (2) prior to July 15.

(C) The TMP shall establish and maintain Capital Accounts in accordance with this Article X. The TMP shall also establish and maintain tax basis capital accounts for each Member. Upon request, the TMP shall submit to each Member along with a copy of any proposed Company income tax return an accounting of their respective Capital Accounts as of the end of the tax return period.

(D) Within two weeks from the receipt of the request from the TMP the Member will furnish the TMP with such information as the TMP may reasonably request to permit it to provide the Internal Revenue Service with sufficient information for purposes of the Code for the proper compliance with the reporting and compliance requirements of the Company.

(E) The TMP shall not agree to any extension of the statute of limitations for making assessments on behalf of any other Member without first obtaining the written consent of that Member. The TMP shall not bind any other Member to a settlement agreement in tax audits without obtaining the written concurrence of any such Member. Any other Member who enters into a settlement agreement with the Secretary of the Treasury with respect to any Company items shall notify the other Members of such settlement agreement and its terms within ninety (90) days from the date of the settlement.

(F) If any Member intends to file a notice of inconsistent treatment under the Code, such Member shall, prior to the filing of such notice, notify the TMP of such intent and the manner in which the Member’s intended treatment of a Company item is (or may be) inconsistent with the treatment of that item by the Company. Within one week of receipt of such notification, the TMP shall remit copies of such notification to other Members of the Company. If an inconsistency notice is filed solely because a Member has not received a Schedule K-1 in time for filing of its income tax return, the TMP need not be notified.

(G) The TMP shall, to the extent and in the manner provided by regulations issued pursuant to the Code, keep all Members informed of all administrative and judicial proceedings for the adjustment at the Company level of Company items.

(H) No Member shall file a request pursuant to the Code for an administrative adjustment of Company items for any Company taxable year without first notifying all other Members. If all other Members agree with the requested adjustment, the TMP shall file the request for administrative adjustment on behalf of the Company. If unanimous consent is not obtained within thirty (30) days from such notice, or within the period required to timely file the request for administrative adjustment, if shorter, any Member, including the TMP, may file a request for administrative adjustment on its own behalf.

(I) Any Member intending to file a petition under the Code with respect to any Company item or to other tax matters involving the Company shall notify the other Member, prior to such filing, of the nature of the contemplated proceeding. In the case where the TMP is the Member intending to file such petition, such notice shall be given within a reasonable time to allow the other Members to participate in the choosing of the forum in which such petition will be filed. If the Members do not agree on the appropriate forum, the TMP shall choose the forum. If a Member intends to seek review of any court decision rendered as a result of such a proceeding, such Member shall notify the other Member prior to seeking such review.

10.06 Elections.

(A) For both income tax return and Capital Account purposes, the Company shall elect: (1) to use the maximum allowable accelerated tax method and the shortest permissible tax life for depreciation purposes, (2) to use the accrual method of accounting, (3) to treat all organizational costs of the Company as deferred expenses amortizable over a sixty (60) month period pursuant to Section 709(b) of the Code and comparable provisions of state law, (4) to amortize start-up expenditures over a sixty (60) month period pursuant to Section 195(d) of the Code and comparable provisions of state law, (5) to report income on the basis of a calendar year. The Company shall pay the TMP for all reasonable costs of hiring an outside accounting firm to assist in the preparation of the federal and Louisiana income tax returns of the Company. The Company shall also pay the TMP for all reasonable costs it may incur in tax accounting required for adjustments attributable to an election under Code Section 754.

(B) Any election other than those referenced above must be approved by the Committee.

10.07 Transfers, Indemnification, and Correspondence.

(A) Transfers of Company interests shall be governed by this Agreement. A Member transferring its interest, or any part thereof, shall notify the TMP in writing within two weeks of such transfer.

(B) This Agreement does not include any indemnification provisions to protect Members against any harm caused by a Code Section 708(b)(1)(B) termination. However, the Members agree that if any of them makes a sale or assignment of its interest under this Agreement, such sale or assignment shall be structured, if reasonably possible, to avoid causing a Code Section 708(b)(1)(B) termination.

(C) All correspondence relating to the preparation and filing of the Company’s income tax returns and capital accounts shall be forwarded to:

PHH MONOMERS, L.L.C.

BUSINESS CONDUCT POLICIES

I. ANTITRUST POLICY

1. It the policy of the Company to comply fully with the antitrust laws of the United States wherever they are applicable, at home and abroad. The Company is mindful that it takes years to earn a good reputation in any field of endeavor but it is an unfortunate fact that all the previously attained good can be wiped out by the acts of a single individual on a single occasion. In the antitrust field, the misconduct of a single employee can involve the employee, the employee’s superior, the Company and its management in costly, arduous litigation which can lead to fines, injunctions and even imprisonment.

2. The purpose of the antitrust laws is to preserve our competitive free enterprise system. The United States antitrust policy is founded on the belief that the public interest is best served by vigorous competition—competition free from collusive agreements among competitors. The fact that the antitrust laws aid in the preservation of our economic, political and social institutions is widely recognized, and the management of this Company has repeatedly stated its belief in the philosophy underlying those laws. Thus, while the attainment of profits by all lawful and proper means is strongly encouraged, the Company’s efforts in that regard must be conducted in accordance with the law. Specifically, this means that participation in agreements or understandings which violate the antitrust laws is contrary to Company policy.

3. The following are examples of activities which violate the United States antitrust laws: agreements or understandings between two or more competitors (1) to fix prices, discounts or terms of sale, (2) to divide markets, customers or territories, or (3) to refuse to deal with, or boycott, third parties. Each of these activities can lead to criminal prosecution and conviction of the individuals involved as well as their companies. Their mention is not intended to minimize the importance of other less obvious activities which may also violate the antitrust laws Any employee who is in doubt as to the propriety of a contemplated course of action should promptly communicate with his or her supervisor or Company counsel before action is taken.

4. The Committee will arrange for the conduct of programs and the publication of materials to educate employees concerning compliance with the antitrust laws so that employees will learn to identify these types of legal problems as they arise.

II. CONFLICTS OF INTEREST POLICY

1. Each employee has a responsibility for honesty and fair dealing in his/her relations with the Company. An employee shall not engage in conduct, or allow a situation to exist, in which the employee’s personal interest conflicts with that responsibility.

2. A conflict of interest can arise in those situations where an employee or close relative can personally profit from a transaction involving the Company and the employee or a third party. A conflict can also occur if the employee places or influences Company business with himself/herself, a privately-held enterprise in which the employee or a close relative of his/her family has a financial interest or a publicly-held enterprise in which the employee or a close relative has a major financial interest. In those circumstances, and in other cases where the employee has a doubt about the propriety of a particular transaction or relationship, the employee must report the matter through his/her reporting chain, to the Committee, who will resolve the matter.

3. An employee may not solicit gifts, entertainment or other personal favors from a supplier, customer or competitor of the Company and in no case shall he/she accept gifts, entertainment or other personal favors such as could improperly influence, or appear to improperly influence, him/her in the performance of his/her duties.

4. An employee may not use confidential business information of the Company for his/her personal benefit or disclose any such information to third parties without proper authorization.

III. PAYMENTS AND EXPENDITURES POLICY

1. No undisclosed or unrecorded fund or account shall be directly or indirectly established for any purpose.

2. No direct or indirect payment or expenditure on behalf of the Company shall be authorized or made with the intention or understanding that any part of such payment or expenditure is to be used for a purpose other than that described by the documents supporting the payment or expenditure.

3. All entries made in the financial records of the Company shall fairly and accurately reflect the facts and circumstances of any payment or expenditure made by the Company.

4. No employee shall make any direct or indirect payment or expenditure or give any gift, to improperly influence, or as would appear to improperly influence, any person in his/her relations with the Company or others.

IV. POLITICAL ACTIVITY POLICY

1. Each employee is encouraged to participate in the electoral process at all levels of government by voting and supporting candidates and issues of his or her choice.

2. No employee shall, directly or indirectly, contribute or expend any of the Company’s money, property, services or other things of value for any use prohibited by laws regulating the electoral process or the political activity of corporations.

3. Employees shall be permitted to meet at Company facilities with candidates or their representatives, as permitted by the applicable federal and state laws. When permitted by the law of a state of the United States where the Company has facilities or a substantial business interest, the Company may make contributions or expenditures to or on behalf of state and local candidates and political committees, and ballot propositions or referenda before such state’s electorate, pursuant to and in accordance with such authorizations and procedures as are established by the Company.

4. No employee of the Company shall, directly or indirectly, cause, influence, or attempt to cause or influence, any officer or employee of the Company to make unlawful political contributions or expenditures to, or on behalf of, candidates or issues, or otherwise engage in any activity violative of applicable law regulating the electoral process or the political activity of corporations.

5. As permitted by the Federal Election Campaign Finance Act of 1971, as amended, or when permitted by the law of a state of the United States where the Company has facilities or a substantial business interest, the proper officers of the Company are authorized to establish and administer, and solicit voluntary contributions form the Company’s employees to, a separate segregated fund or funds to be used by the Company for the purpose of influencing the nomination or election of any person to federal, state or local office. Contributions to such funds by any employee shall be strictly a matter of his or her personal choice. Under no circumstance is any employee authorized, and every employee is expressly forbidden, directly or indirectly, to threaten, extort, coerce or otherwise improperly influence another employee’s participation in any such fund.

6. Because the Company has an interest in making its views known on subjects affecting the Company’s business at various levels of government, Company employees or agents are properly in contact and communication with legislators and government employees in a variety of circumstances. Each employee or agent of the Company is forbidden from engaging in any conduct which would improperly influence a legislator or other government employee in the performance of his or her duties.

7. The Company shall, on occasion and through appropriate forums, make its views known to its employees and the public on matters of public interest which affect the

Company’s business. The proper officers of the Company are authorized and directed to publish guidelines regarding the Company’s participation in government affairs and make the same available to employees.

V. INSIDE INFORMATION POLICY

An employee shall not trade in the securities of any Member, directly or derivatively, while in possession of inside information and shall not disclose such information to any third party without proper authorization. Generally, inside information is information which is both material and nonpublic. If an employee is in doubt about whether he/she is in possession of inside information he/she should consult the Committee.

VI. CRIME PREVENTION POLICY

The Federal Sentencing Guidelines for Organizational Defendants (“Guidelines”), which address criminal conduct by corporations, became effective November 1, 1991. A corporation can act only through its agents and employees and, under federal criminal law, can be criminally liable for offenses committed by its agents or employees. The Guidelines provide for both a broad range of penalties, including multi-million dollar fines, and incentives in the form of mitigation to encourage corporations to maintain internal policies and programs to prevent, detect and report criminal conduct. In addition to exposing the Company to substantial financial risk, an employee or agent who breaks the law faces possible imprisonment and fines.

The Company’s Crime Prevention Policy is the following:

1. Every employee and agent acting on behalf of the Company is required to fully comply with all criminal laws of the United States and all jurisdictions in which the Company operates.

2. Employees and agents shall exercise due care when delegating substantial discretionary authority to insure that individuals selected are well informed and understand their responsibility to comply with the Company’s Business Conduct Policies.

3. Every employee shall report to his/her supervisor or to the Committee any abuses, or suspected abuses, of the Business Conduct Policies and any criminal conduct or suspected criminal conduct. No employee may intimidate or impose any form of retribution on any employee who makes such a report. In connection with an employee’s duty to report suspected abuses of the Business Conduct Policies or suspected criminal conduct,

he/she should understand that he/she has a duty not to ignore facts and circumstances which would reasonably indicate misconduct. Rather, he/she has a duty to be alert to the existence of such facts and circumstances and to report them to his/her supervisor or to the Committee.

FIRST AMENDMENT TO OPERATING AGREEMENT

THIS FIRST AMENDMENT TO THE OPERATING AGREEMENT of PHH Monomers, LLC, is made this 30th day of September 1996 by and between CONDEA Vista Company, a Delaware corporation with offices at 900 Threadneedle, Houston, Texas 77079-2990 (“Vista”), PPG Industries, Inc., a Pennsylvania corporation with offices at One PPG Place, Pittsburgh, Pennsylvania 15272 (“PPG”) and PHH Monomers, L.L.C., a Louisiana limited liability company with offices at Columbia Southern Road, Lake Charles, Louisiana 70602 (the “Company”).

WHEREAS, Vista, PPG and the Company executed an Operating Agreement (“Agreement”) dated June 7, 1995; and

WHEREAS, Exhibit B to the Agreement contains certain tax allocation provisions which will become operative upon the occurrence of certain conditions, which conditions have in fact occurred; and

WHEREAS, the parties desire and intend to amend the Agreement and Exhibit B thereto as set forth herein:

NOW, THEREFORE, in consideration of the mutual covenants contained herein and intending to be legally bound hereby, Vista, PPG and the Company agree as follows:

I. Exhibit B to the Agreement is hereby revoked and cancelled in its entirety. Article X and Article XI of the Agreement are hereby revoked and cancelled in their entirety, and in their place are substituted a new Article X and a new Article XI, in form and substance as follows:

ARTICLE X

TAX MATTERS

10.01 Tax Characterization and Returns.

(A) The Members acknowledge that the Company will be treated as a “partnership” for federal and Louisiana state tax purposes. All provisions of the Company’s articles of organization and this Agreement are to be construed so as to preserve that tax status.

(B) �� Within ninety (90) days after the end of each fiscal year, the Accounting Member will cause to be delivered to each person who was a Member at any time during such fiscal year a Form K-l and such other information, if any, with respect to the Company as may be necessary for the preparation of each Member’s federal or state income tax (or information)

returns, including a statement showing each Member’s share of income, deduction, gain, loss, deduction and credits for the fiscal year.

10.02 Capital Accounts.

The Company will establish a capital account for each Member (hereinafter referred to as “Capital Account”) in accordance with Regulation Section 1.704-l(b)(2)(iv) and will maintain each account according to the following rules:

(a) Increases to Capital Account. The Capital Account shall be increased by (a) the amount of the Member’s capital Contribution made in cash; (b) the agreed fair market value of any Contributions of property (net of liabilities that the Company is considered to assume or take subject to); and (c) the amount of income and gain, or items thereof, allocated to the Member pursuant to this Agreement.

(b) Decreases to the Capital Account. The Capital Account shall be decreased by (a) the amount of money and the fair market value of property distributed to each Member (net of liabilities assumed by such Member or to which the property is subject); (b) that Member’s allocated share of Company loss and deduction, or items thereof; and (c) any basis decreases required by the Code.

(c) Adjustments with Respect to Contributed Property. In accordance with Regulation Sections 1.704-l(b)(2)(iv)(d)(3) and 1.704-l(b)(2)(iv)(g), in the case of property contributed to the Company, the contributing Members’ Capital Accounts shall be increased or decreased for items of depreciation, amortization, gain or loss computed for book purposes with respect to such property in the same manner as such items would be computed if the adjusted tax basis of such property were equal to its fair market value on the date of its Contribution to the Company. In accordance with Regulation Section 1.704-l(b)(2)(iv)(g)(3), the amount of book depreciation or amortization for a period with respect to contributed property shall be the amount that bears the same relationship to the book value of such property as the depreciation or amortization computed for tax purposes with respect to such property for such period bears to the adjusted tax basis of such property; provided that, if such property has a zero adjusted tax basis, the book depreciation or amortization shall be computed over a period of time and at a rate of recovery that corresponds to the applicable recovery period and applicable depreciation method, respectively, as prescribed in Section 168(a) of the Code, for newly-acquired property of such type, but without taking into account any applicable convention described in Section 168(d). For this purpose, it is agreed that such determinations shall be made so as to result in the most accelerated curative allocations relating to Section 704(c) property as provided in Section 10.04, thereby ignoring any elections available under Section 168 that would result in less accelerated curative allocations, including, but not limited to, the elections set forth in Sections 168(b)(2)(C), 168(b)(3)(D) and 168(g)(7). The fair market value of property contributed to the Company shall be based upon the agreed net fair market value of the property under Article IV hereof.

(d) Adjustments for Unrealized Gain and Unrealized Loss. For purposes of computing and maintaining Capital Accounts pursuant to this Section 10.02, immediately prior to the distribution of any asset of the Company to a Member (including a distribution in liquidation of the Company), the amount of unrealized gain with respect to the asset shall be deemed to be an item of Capital Account income or gain recognized by the Company and shall be allocated to the Members as provided in Section 10.03 of this Agreement, and the amount of unrealized loss with respect to the asset shall be deemed to be an item of Capital Account deduction or loss recognized by the Company and shall be allocated to the Members as provided in Section 10.03 of this Agreement. For this purpose, the unrealized gain with respect to an asset of the Company shall be equal to the excess of the value of the asset over its adjusted book basis of the asset and the unrealized loss with respect to an asset of the Company shall be equal to the adjusted book basis of the asset over the distribution value of the asset as determined under Section 10.02(b).

(e) Capital Accounts of Transferees. A transferee of an interest in the Company shall succeed to the Capital Account attributable to the interest, and there shall be no adjustment to the Capital Account as a result of the Transfer; provided, however, that if the Transfer causes a deemed termination of the Company pursuant to Section 708(b)(1)(B) of the Code, the assets of the Company shall be deemed to have been distributed to the Members (including the transferee) in liquidation of the Company and recontributed by the Members in reconstitution of the Company. The Capital Accounts of the Company following the deemed reconstitution shall be maintained in accordance with the principles of this Section 10.02.

(f) Compliance with Regulations. The Operator shall make all other adjustments to the Capital Accounts required by Regulation Section 1.704-l(b)(2)(iv).

(g) Book basis of an asset for the Company shall be the cost to the Company for an asset acquired by purchase or the fair market value of the asset for an asset acquired from a Member in contribution to the Company. Adjusted book basis is book basis with adjustment required under this Section 10.02. A Member’s book basis is the Member’s share of book basis which is reflected in the Member’s Capital Account. The tax basis and adjusted tax bases of an asset to the Company are as determined under the Code.

10.03 Allocations.

(a) Sharing of Expenditures and Revenues. All expenses and revenues of the Company shall be determined and charged or credited, as the case may be, to the Members in accordance with the provisions of this Section. Subject to the provisions of this Section 10.03, expenditures and revenue of the Company shall be shared by the Members in each Member’s respective Sharing Ratio.

(b) Allocations for Capital Account Purposes.

(1) Capital Account Deductions and Capital Account Gross Income. Except as otherwise provided in this Section 10.03, for purposes of maintaining Capital Accounts pursuant to Section 10.02, (i) each item of income and gain shall be allocated in the same proportion as the corresponding item of income and gain is allocated pursuant to Section 10.04; and (ii) each item of deduction or loss shall be allocated in the same proportion as the corresponding item of loss or deduction is allocated pursuant to Section 10.04, with the exception of book depreciation relating to property contributed by a Member, which shall be allocated in accordance with each Member’s Sharing Ratio.

(2) Gain and Loss. For purposes of computing and maintaining Capital Accounts pursuant to Section 10.02, gain or loss with respect to the disposition of any Company property or asset shall be allocated in accordance with the Members’ Sharing Ratios.

(c) Section 705(a)(2)(B) Expenditures. For purposes of computing and maintaining Capital Accounts pursuant to Section 10.02 of this Agreement, each Section 705(a)(2)(B) expenditure of the Company shall be allocated in the same proportion as the cost giving rise to the Section 705(a)(2)(B) expenditure is charged pursuant to Section 10.03(a) above.

10.04 Allocation for Federal Income Tax Purposes.

(a) Income, Gains, Losses and Deductions. For federal income tax purposes, except as otherwise provided in this Section 10.04, all items of Company income, gain, loss, and deduction with respect to a taxable year of the Company shall be allocated to the Members as follows:

(1) Any income arising from a sale of raw materials, feedstock, inventory, or products produced by the Company’s operations shall be allocated in accordance with Article V of this Agreement.

(2) Deductions arising from operating expense shall be allocated to the Members in the same manner in which they contributed to the costs of operations under this Agreement.

(3) Depreciation with respect to contributed property with a beginning book basis that differs from its adjusted tax basis in the hands of the contributing Member immediately preceding the date of Contribution (“Section 704(c) property”), shall be allocated for income tax purposes pursuant to Regulations promulgated under Section 704(c) of the Code. Such depreciation shall be allocated between the Members in accordance with the traditional method with curative allocations as set forth in Regulation Section 1.704-3 (c).

(A) Curative allocations to a Member (the “Noncontributing Member”) relating to tax depreciation or amortization of Section 704(c) property contributed by the other Member (the “Contributing Member”) shall be made first, from the Contributing Member’s allocable share of tax depreciation or amortization attributable to other Company property contributed by the Contributing Member; second, from the Contributing Member’s allocable share of tax depreciation or amortization attributable to Company property constructed by the Company or property acquired other than by a Contribution from a Member; third, from the Contributing Member’s allocable share of tax depreciation or amortization attributable to Company property contributed by the Noncontributing Member; and fourth, by a curative allocation to the Contributing Member of gain from the disposition of the contributed property subject to the ceiling rule that would have been allocated to the Noncontributing Member, in an amount sufficient to offset any remaining effect of the “ceiling rule” limitation in accordance with Regulation Section 1.704-3(c)(3)(iii)(B). A property shall be considered acquired other than by Contribution to the extent Code Section 721 does not apply to the acquisition of the property by the Company.

(i) If a curative allocation from the sources specified in paragraph (A) above is not sufficient to fully offset the effect of the “ceiling rule” limitation, the amount of the excess of the full potential curative allocation for the year over the amount of the actual curative allocation for a year shall be carried forward to the next year (and to succeeding years, if necessary, to fully satisfy the sum of the difference between cumulative book and tax depreciation or amortization), provided, however, the source of the allocation shall be as specified in paragraph (A) for the year and this carryover provision shall be subject to the provision of Regulation Section 1.704-3(c) relating to unreasonable curative allocations.

(ii) Consistent with Section 10.02(c), the curative allocations with respect to specific Section 704(c) property of the Company that had a zero adjusted tax basis to the Company immediately after the Contribution of such property to the Company shall be made over a period of time and at a rate of recovery that corresponds to the applicable recovery period and applicable depreciation method, respectively, as prescribed in Section 168(a), for newly-acquired property of such type, but without taking into account any applicable convention described in Section 168(d). For this purpose, it is agreed that such determinations shall be made so as to result in the most accelerated curative allocations, thereby ignoring any elections available under Section 168 that would result in less accelerated curative allocations, including, but not limited to, the elections set forth in Sections 168(b)(2)(C), 168(b)(3)(D) and 168(g)(7).

(B) Gains and losses shall be allocated in accordance with Section 10.04(a)(5) below.

(4) The Members agree that the capital additions to the Existing VCM Plant funded with Vista’s Contribution to the Company will be accounted for at a value equal to the Company’s cost of construction and shall not constitute Section 704(c) property. Depreciation on Company property shall be allocated to Member’s Capital Accounts in accordance with the Members’ Sharing Ratios except as modified by this Article 10.04(a) to give effect to the election of the Members to use curative allocations for Section 704(c) property.

(5) Gain and Loss. Taxable gain or loss on a sale, exchange, retirement, or other disposition of Company property that is not Section 704(c) property shall be allocated in accordance with the Members’ Sharing Ratios. Gain or loss on a sale, exchange, retirement, or other disposition of Company property that is Section 704(c) property shall be allocated by the Members in accordance with the traditional method with curatives as set forth in Regulation Section 1.704-3(c). Curative allocations to the Noncontributing Member relating to gain or loss recognized on a disposition of Section 704(c) property contributed by the Contributing Member shall be made first, from the Contributing Member’s allocable share of gain or loss recognized on a disposition of other Company property contributed by the Contributing Member; second, from the Contributing Member’s allocable share of gain or loss recognized on a disposition of Company property contributed by the Noncontributing Member; third, from the Contributing Member’s allocable share of gain or loss recognized on a disposition of Company property constructed by the Company or property acquired other than by a Contribution from a Member; fourth, from items of deduction, loss, income or gain of the Company other than such gain or loss (including, but not limited to, depreciation or amortization that would otherwise be allocable to the Contributing Member), in accordance with Regulation Section 1.704-3(c)(3)(iii)(B); and fifth, from costs specifically allocable to the Contributing Member as provided in Article V.

(6) Deductions or tax expense arising from costs incurred by the Company and charged to the Members under Article V shall be allocated for tax purposes to the Members in the same manner as such costs are charged to the Members under such Article V.

(7) Except as otherwise provided in Section 10.04(a)(1) of this Agreement, any other item of income or loss shall be allocated in accordance with the accounting for the revenue or expense, respectively, that gives rise to such item of income or loss.

(b) Recapture Income. To the extent of any recapture income resulting from the sale or other disposition of an asset of the Company, the amount of any gain from the disposition allocated to (or recognized by) a Member for federal income tax purposes pursuant to the above provisions shall be deemed to be recapture income to the extent the Member (or its predecessor in interest) has been allocated or has claimed any deduction directly or indirectly giving rise to the treatment of the gain as recapture income.

(c) Qualified Income Offset. Notwithstanding any other provisions of this Agreement to the contrary, if, with respect to any taxable year of the Company, a Member receives an adjustment, allocation or distribution of the type described in Section 1.704-(b)(2)(ii)(d)(4), (5), or (6) of the Regulations that results in such Member’s adjusted Capital Account having a negative balance, Capital Account gross income (and the corresponding items of income or gain for federal income tax purposes) and the amount realized on the disposition of a Company property for that taxable year and all subsequent taxable years shall be allocated to that Member in an amount necessary to eliminate the negative balance in the Member’s adjusted Capital Account as quickly as possible. The provisions of this Section 6.4 are intended to constitute a “qualified income offset” within the meaning of Section 1.704-l(b)(2)(ii)(d)(3) of the Regulations and shall be construed in accordance with that intention.

(d) Minimum Gain Chargeback. Beginning in the first taxable year in which there are “nonrecourse deductions” or a distribution is made of proceeds of a nonrecourse liability that are allocable to an increase in the minimum gain of the Company, as determined under the rules of Section 1.704-2(e)(3) of the Regulations, and thereafter throughout the full term of the Company, the “Minimum Gain Chargeback” rules of Section 1.704-2(f) of the Regulations, shall apply with respect to the allocation of all Company items in those year(s). If there is a net decrease during a taxable year of partner nonrecourse debt minimum gain within the meaning of Section 1.704-2(i)(3), then the chargeback rules of Section 1.704-2(i)(4) shall apply.

(e) Allocations with Respect to Deficit Members. Notwithstanding any of the foregoing provisions of Section 10.04 to the contrary, if during any fiscal year of the Company the allocation of any loss or deduction (net of any income or gain) to a Member (the “Deficit Members) would cause or increase a negative balance in the Member’s adjusted Capital Account as of the end of that fiscal year, only the amount of such loss or deduction that reduces the balance to zero shall be allocated to the Member and the remaining amount shall be allocated to the Member whose adjusted Capital Account has a positive balance remaining at that time. At such time as all Members have a zero balance in their Member’s Capital Account, further loss or deductions shall be allocated between the Members in accordance with the provisions of Section 10.04(A)(2)-(7).

(f) Curative Allocations. Any special allocations of items of income pursuant to Section 10.04(c)-(e) shall, to the extent consistent with such Section, be taken into account in computing subsequent allocations of deduction and loss, so that the resulting Capital Account balance of each Member shall, to the maximum extent possible consistent with such Sections, be equal to the balances that would have existed if such special allocations had not occurred. The preceding sentence shall only be applied before taking into account any gain or deemed gain from the sale or deemed sale of Company properties.

(g) Allocations Attributable to Transferred Interests. If a Member transfers an interest in the Company during a taxable year, items of Company income, loss, deduction and credit attributable to the transferred interest shall be allocated between the transferor and the

transferee pursuant to any agreement between the transferor and transferee which is submitted to the Accounting Member and which is consistent with Section 706 of the Code.

10.05 Tax Matters.

(A) The Operator is designated as the Tax and Financial Accounting Matters Member (“Accounting Member”) and shall serve as the Tax Matters Partner as such term is defined in the Code and, so long as such Operator remains a Member, shall serve until replaced by action of the Committee. In the event of any change in the Accounting Member, the Member serving as Accounting Member at the beginning of a given taxable year shall continue as Accounting Member with respect to all matters concerning such year. The Accounting Member and the other Member(s) shall use their best efforts to comply with responsibilities outlined in this Section and in the Code (including any Treasury Regulations promulgated thereunder) and in doing so shall incur no liability to any other Member. Notwithstanding the Accounting Member’s obligation to use its best efforts in the fulfillment of its responsibilities, the Accounting Member shall not be required to incur any expenses for the preparation for, or pursuance of administrative or judicial proceedings, unless the Members agree on a method for sharing such expenses.

(B) The Accounting Member shall prepare and file all required federal, state, and local Company income tax returns, as well as all sales, use and other excise tax returns. In preparing such returns the Accounting Member shall use its best efforts and in doing so shall incur no liability to any other Member with regard to such returns. The Accounting Member shall submit to each Member a copy of the income tax returns as proposed for review (1) not less than thirty (30) days prior to the due date (including extensions) and (2) prior to July 15.

(C) The Accounting Member shall establish and maintain Capital Accounts in accordance with this Article X. The Accounting Member shall also establish and maintain tax basis capital accounts for each Member. Upon request, the Accounting Member shall submit to each Member along with a copy of any proposed Company income tax return an accounting of their respective Capital Accounts as of the end of the tax return period.

(D) Within two weeks from the receipt of the request from the Accounting Member the Member will furnish the Accounting Member with such information as the Accounting Member may reasonably request to permit it to provide the Internal Revenue Service with sufficient information for purposes of the Code for the proper compliance with the reporting and compliance requirements of the Company.

ARTICLE XI

DISSOLUTION AND LIQUIDATION

11.01 Dissolution.

(a) Dissolution of the Company shall be governed by the Act. Notwithstanding the foregoing, any remaining Member(s) shall have the right to continue the Company upon the interdiction, withdrawal, resignation, expulsion, bankruptcy or dissolution of a Member or occurrence of any other event which terminates the continued membership of a Member in the Company, and the Company shall continue so long as all remaining Member(s) agree(s) to continue the Company within ninety (90) days after such termination event with respect to a Member, and the surviving Entity shall thereafter be the “Company”. The remaining Member(s) may establish and effectuate a plan by which the Company merges with or into another Entity pursuant to the Act or other applicable Law. A sole remaining Member may elect to continue the business of the Company as a sole proprietorship.

(b) In the event the Company is “liquidated” within the meaning of Regulation Section 1.704-l(b)(2)(ii)(g), distributions shall be made pursuant to this Article XI to the Member(s) who has (have) positive Capital Accounts in compliance with Regulation Section 1.704-l(b)(2)(ii)(b)(2) to the extent of, and in proportion to, positive Capital Account balances. If any Member has a deficit balance in its Capital Account (after giving effect to all Contributions, distributions and allocations for all taxable years, including the year during which such liquidation occurs), such Member shall have no obligation to make any Contribution to the capital of the Company with respect to such deficit, and such deficit shall not be considered a debt owed to the Company or to any other person for any purpose whatsoever. A pro rata portion of the distributions that would otherwise be made to the Members pursuant to this Article XI may be withheld or escrowed to provide a reasonable reserve for Company liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Company, provided that such withheld or escrowed amounts shall be distributed to the Members as soon as practicable.

(c) Notwithstanding any other provision of this Article XI, in the event the Company is liquidated within the meaning of Regulation Section 1.704-l(b)(2)(ii)(g) but no Liquidating Event has occurred, the Company’s property shall not be liquidated, the Company’s liabilities shall not be paid or discharged, and the Company’s affairs shall not be wound up. Instead, for federal income tax purposes the Company shall be deemed to have distributed its property in kind to the Members, who shall be deemed to have assumed and taken such property subject to all Company liabilities, all in accordance with their respective Capital Accounts. Immediately thereafter, the Members shall be deemed to have recontributed the Company property in kind to the Company, which shall be deemed to have assumed and taken such property subject to all liabilities.

IN WITNESS WHEREOF, PPG and Vista place their signatures on the day and year set forth above.
