ARTICLE IV

ADMISSION OF MEMBERS; DISPOSITION OF MEMBERSHIP INTERESTS

Section 4.1 General Restriction.

A Member may not Dispose of all or any portion of its Membership Interests except in strict accordance with this Article IV. References in this Article IV to Dispositions of a Membership Interest shall also refer to Dispositions of a portion of a Membership Interest. Any attempted Disposition of a Membership Interest, other than in strict accordance with this Article IV, shall be, and is hereby declared, null and void ab initio. The Members agree that a breach of the provisions of this Article IV may cause irreparable injury to the Company and to the other Members for which monetary damages (or other remedy at law) are inadequate in view of (a) the complexities and uncertainties in measuring the actual damages that would be sustained by reason of the failure of a Member to comply with such provision and (b) the uniqueness of the business of the Company and the relationship among the Members. Accordingly, the Members agree that the provisions of this Article IV may be enforced by specific performance.

Section 4.2 Admission of Assignee as a Member.

An Assignee has the right to be admitted to the Company as a Member, with the Membership Interests (and attendant Sharing Ratio) so transferred to such Assignee, only if (a) the Member making the Disposition (a “Disposing Member”) has granted the Assignee either (i) all, but not less than all, of such Disposing Member’s Membership Interests or (ii) the express right to be so admitted and (b) such Disposition is effected in strict compliance with this Article IV.

Section 4.3 Requirements Applicable to All Dispositions and Admissions.

Any Disposition of Membership Interests and any admission of an Assignee as a Member shall also be subject to the following requirements, and such Disposition (and admission, if applicable) shall not be effective unless such requirements are complied with:

(a) Payment of Expenses. The Disposing Member and its Assignee shall pay, or reimburse the Company for, all reasonable costs and expenses incurred by the Company in connection with the Disposition and admission of the Assignee as a Member.

(b) No Release. No Disposition of Membership Interests shall effect a release of the Disposing Member from any liabilities to the Company or the other Members arising from events occurring prior to the Disposition, except as otherwise may be provided in any instrument or agreement pursuant to which a Disposition of Membership Interests is effected.

ARTICLE V

CAPITAL CONTRIBUTIONS

Section 5.1 Initial Capital Contributions.

At the time of the formation of the Company, UCI, as the initial or organizational Member of the Company, made the Capital Contribution as set forth next to the Member’s name on Exhibit A.

Section 5.2 Loans.

If the Company does not have sufficient cash to pay its obligations, any Member(s) that may agree to do so may advance all or part of the needed funds to or on behalf of the Company. An advance described in this Section 5.2 constitutes a loan from the Member to the Company, bears interest at a rate determined by the Members from the date of the advance until the date of payment and is not a Capital Contribution.

Section 5.3 Return of Contributions.

Except as expressly provided herein, no Member is entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its Capital Account or its Capital Contributions. A Capital Contribution remaining unpaid by the Company is not a liability of the

Company or of any Member. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital Contributions.

Section 5.4 Capital Accounts.

An individual Capital Account shall be established and maintained for each Member. A Member that has more than one class or series of Membership Interest shall have a single Capital Account that reflects all such classes or series of Membership Interests, regardless of the classes or series of Membership Interests owned by such Member and regardless of the time or manner in which such Membership Interests were acquired. Upon the Disposition of all or a portion of a Membership Interest, the Capital Account of the Disposing Member that is attributable to such Membership Interest shall carry over to the Assignee in accordance with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(l).

ARTICLE VI

DISTRIBUTIONS AND ALLOCATIONS

Section 6.1 Distributions.

Except as otherwise provided in Section 6.2, distributions to the Members shall be made only to all Members simultaneously in proportion to their respective Sharing Ratios (at the time the amounts of such distributions are determined) and in such aggregate amounts and at such times as shall be determined by the Members representing a Majority Interest (at the time the amounts of such distributions are determined); provided, however, that any loans from Members pursuant to Section 5.2 shall be repaid prior to any distributions to Members pursuant to this Section 6.1.

Section 6.2 Distributions on Dissolution and Winding Up.

Upon the dissolution and winding up of the Company, after adjusting the Capital Accounts, if any, for all distributions made under Section 6.1 and all allocations under Article VI, all available proceeds distributable to the Members as determined under Section 12.2 shall be distributed (i) to all of the Members in amounts equal to the Members’ positive Capital Account balances, or (ii) if the obligation to maintain Capital Accounts has been suspended under Section 13.12 of this Agreement, to the sole Member.

Section 6.3 Allocations.

Subject to the allocation rules of Section 6.3(c), (d) and (e) hereof, Profits and Losses of the Company for any fiscal year shall be allocated as follows:

(a) Profits for any fiscal year shall be allocated in the following order of priority:

(i) First, to all Members, in proportion to the deficit balances (if any) in their Capital Accounts, in an amount necessary to eliminate any deficits in the Members’ Capital Accounts and restore such Capital Accounts balances to zero;

(ii) Second, to the Members until each Member has been allocated an amount equal to the amount distributed to such Member pursuant to Section 6.1 in the current and in all previous fiscal years in excess of amounts previously allocated to such Members pursuant to this Section 6.3(a)(ii);

(iii) Third, to the Members, to the greatest extent possible, an amount required to cause the positive Capital Account balances of each of the Members to be in the same proportion as the Member’s respective Sharing Ratios; and

(iv) Thereafter, to the Members in proportion their respective Sharing Ratios.

(b) Losses for any fiscal year shall be allocated in the following order of priority:

(i) First, to the Members, to the greatest extent possible, an amount required to cause the positive Capital Account balances of each of the Members to be in the same proportion as the Member’s respective Sharing Ratios;

(ii) Next, to the Members in proportion to their respective Sharing Ratios until the Capital Account balances of such Members have been reduced to zero;

(iii) Next, to any Member that has a positive Capital Account balance until the Capital Account balances of all of the Members have been reduced to zero; and

(iv) Thereafter, to the Members in proportion to their respective Sharing Ratios.

(c) Notwithstanding the allocation provisions of Section 6.3(a) and (b), if the allocation of Profits or Losses to a Member pursuant to Sections 6.3(a) and (b) in the current fiscal year would cause a Member to have a positive Capital Account balance that is greater than or less than the amount that has been distributed to such Member in the current fiscal year pursuant to Section 6.1, then the allocations of Profits and Losses in the current fiscal year shall be adjusted, to the greatest extent possible, to cause the positive Capital Account balances of each Member to equal the amount of distributions made to such Member in the current fiscal year. In addition, in the event of the dissolution of the Company pursuant to Section 12.1 hereof, if the allocation of Profits or Losses to a Member pursuant to Sections 6.3(a) and (b) would cause a Member to have a Capital Account balance in an amount that is greater than or less than the Member’s Target Capital Account Amount, then the allocations of Profits and Losses shall be adjusted, to the greatest extent possible, to cause the positive Capital Account balances of each Member to equal such an amount.

(d) The following special allocations shall be made in the following order:

(i) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Company income and gain shall be specially allocated to each such Member in an amount and manner sufficient to

restore, to the extent required by the Treasury Regulations, the Member’s Adjusted Capital Account Deficit of such Member as quickly as possible, provided that an allocation pursuant to this Section 6.3(d)(i) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article VI have been tentatively made as if this Section 6.3(d)(i) was not in this Agreement.

(ii) Gross Income Allocation. In the event any Member has a deficit Capital Account at the end of any Company fiscal year which is in excess of the sum of (x) the amount such Member is obligated to restore pursuant to any provision of this Agreement and (y) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentence of Treasury Regulation Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 6.3(d)(ii) shall be made only if and to the extent that such Member would have a deficit Capital Account balance in excess of such sum after all other allocations provided for in this Article VI have been made as if Section 6.3(d)(i) hereof and this Section 6.3(d)(ii) were not in this Agreement.

(iii) Section 754 Adjustments. To the extent an adjustment of the adjusted tax basis of any Company asset pursuant to Section 734(b) of the Code or Section 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such section of the Treasury Regulations.

(e) In accordance with Section 704(c) of the Code and the Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of same under this Agreement). In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value hereof, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Section 704(c) of the Code and the Treasury Regulations thereunder. Any elections or other decisions relating to such allocations shall be made by the Tax Matters Officer in any manner that reasonably reflects the purpose and intention of this Agreement, provided that the Company shall use the remedial allocation method set forth in Treasury Regulation Section 1.704-3(d). Allocations pursuant to this Section 6.3(e) are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

Section 6.4 Varying Interests.

All items of income, gain, loss, deduction or credit shall be allocated, and all distributions shall be made, to the Persons shown on the records of the Company to have been Members as of the last calendar day of the period for which the allocation or distribution is to be made. Notwithstanding the foregoing, if during any taxable year there is a change in any Member’s Sharing Ratio, the Members agree that their allocable shares of such items for the taxable year shall be determined on any method determined by the Board to be permissible under Code Section 706 and the related Treasury Regulations to take account of the Members’ varying Sharing Ratios.

Section 6.5 Withheld Taxes.

All amounts withheld pursuant to the Code or any provision of any state or local tax law with respect to any payment, distribution or allocation to the Company or the Members shall be treated as amounts distributed to the Members pursuant to this Article VI for all purposes of this Agreement. The Board is authorized to withhold from distributions, or with respect to allocations, to the Members and to pay over to any federal, state or local government any amounts required to be so withheld pursuant to the Code or any provision of any other federal, state or local law and shall allocate such amounts to those Members with respect to which such amounts were withheld.

Section 6.6 Limitations on Distributions.

Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to any Member on account of its interest in the Company if such distribution would violate Section 18-607 of the Act or other Applicable Law.

Any indemnification pursuant to this Section 9.1 shall be made only out of the assets of the Company, it being agreed that the Members shall not be personally liable for such indemnification and shall have no obligation to contribute or lend any monies or property to the Company to enable it to effectuate such indemnification.

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 9.1(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to a determination that the Indemnitee is not entitled to be indemnified upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 9.1.

(c) The indemnification provided by this Section 9.1 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, as a matter of law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity (including any capacity under the Purchase Agreement (as such term is defined in the Partnership Agreement)), and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

(d) The Company may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance on behalf of the Indemnitees, the Company and its Affiliates and such other Persons as the Company shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Company’s activities or such Person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e) For purposes of this Section 9.1, the Company shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Company also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to Applicable Law shall constitute “fines” within the meaning of Section 9.1(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the

interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Company.

(f) An Indemnitee shall not be denied indemnification in whole or in part under this Section 9.1 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(g) The provisions of this Section 9.1 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(h) No amendment, modification or repeal of this Section 9.1 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Company, nor the obligations of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 9.1 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

(i) THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 9.1 ARE INTENDED BY THE PARTIES TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT.

Section 9.2 Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Company, the Partnership, the Members or any other Persons who have acquired membership interests in the Company, for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(b) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Company, such Indemnitee acting in connection with the Company’s business or affairs shall not be liable to the Company or to any Member for its good faith reliance on the provisions of this Agreement.

(c) Any amendment, modification or repeal of this Section 9.2 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 9.2 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in

whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

The liquidator shall proceed diligently to wind up the affairs of the Company and make final distributions as provided herein and in the Act.

B. with respect to all Company property that has not been sold, the fair market value of that property shall be determined and the Capital Accounts of the Members shall be adjusted to reflect the manner in which the unrealized income, gain, loss, and deduction inherent in property that has not been reflected in the Capital Accounts previously would be allocated among the Members if there were a taxable disposition of that property for the fair market value of that property on the date of distribution; and

C. Company property (including cash) shall be distributed among the Members in accordance with Section 6.2; and, to the extent practicable, those distributions shall be made by the end of the taxable year of the Company during which the liquidation of the Company occurs (or, if later, 90 Days after the date of the liquidation);

provided, however, that notwithstanding the foregoing provisions of clauses (A), (B) and (C) immediately above, if the obligation to maintain Capital Accounts has been suspended under Section 13.12 of this Agreement, no allocations shall be made and all Company property shall be distributed to the sole Member.

Section 13.4 Effect of Waiver or Consent.

Except as otherwise provided in this Agreement, a waiver or consent, express or implied, to or of any breach or default by any Member in the performance by that Member of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Member of the same or any other obligations of that Member with respect to the Company.

In the event of a direct conflict between the provisions of this Agreement and any mandatory, non-waivable provision of the Act, such provision of the Act shall control. If any provision of the Act may be varied or superseded in a limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter. If any provision of this Agreement or the application thereof to any Member or circumstance is held invalid or unenforceable to any extent, (a) the remainder of this Agreement and the application of that provision to other Members or circumstances is not affected thereby, and (b) the Members shall negotiate in good faith to replace that provision with a new provision that is valid and enforceable and that puts the Members in substantially the same economic, business and legal position as they would have been in if the original provision had been valid and enforceable.
