PARTNERSHIP INTERESTS

2.1 Partnership Interests.

(a) The ownership interests in the Partnership shall consist of limited partner interests referred to as the “LP Partnership Interests” and general partner interests referred to as the “GP Partnership Interests”, all of which shall be uncertificated. At all times, (x) each Limited Partner shall hold one or more LP Partnership Interests and (y) each General Partner shall hold one or more GP Partnership Interests (and may hold one or more LP Partnership Interests).

(b) The number of GP Partnership Interests and LP Partnership Interests held by each Partner as of the date of this Agreement is set forth opposite such Partner’s name on Schedule A hereto in the columns entitled “GP Partnership Interests” and “LP Partnership Interests”, respectively. All such GP Partnership Interests and LP Partnership Interests have been validly issued, and constitute valid partnership interests in the Partnership. Such schedule shall be updated from time to time by the General Partner, without further action by the Limited Partners, to reflect the changes in the information thereon that occur pursuant to this Agreement and that otherwise are not in violation of the terms of this Agreement or the Act. Any GP Partnership Interests or LP Partnership Interests sold to any Partner shall be subject to the terms and conditions of this Agreement.

2

(c) The number and kind of shares or other equity interests to which Partnership Interests may relate and the number and kinds of securities deliverable shall be proportionally adjusted, as deemed by the General Partner to be equitable and appropriate to the Partners, in the event of any extraordinary dividend, stock split, share combination, recapitalization, merger, consolidation, reorganization, exchange of shares or other equity interests or any other similar event affecting the Partnership or any of its subsidiaries.

(d) The Partnership Interests reflected on Schedule A as of the date of this Agreement are intended for U.S. federal income tax purposes to be, and shall be treated for all purposes of this Agreement (including this Section 2.1) to be, a continuation of the GP Units, Common Units and Profits Units outstanding under the Original Agreement.

ARTICLE III

DISTRIBUTIONS

3.1 Distributions Generally. Subject to Section 3.2 and Section 4.1, when the General Partner determines that the Partnership shall distribute any cash or other property of the Partnership (which shall be valued at fair market value), such amounts or property shall be distributed to the Partners in accordance with this Section 3.1. Any amounts distributable to the Partners pursuant to this Section 3.1 shall be distributed as follows:

(a) Subject to the other provisions of this Section 3.1, to the Partners in proportion to the aggregate number of Partnership Interests held by each Partner as of the time of such distribution.

(b) The General Partner may increase or decrease a distribution that would otherwise be made to any Partner pursuant to Section 3.1(a) (including, for the avoidance of doubt, by making distributions to some Partners but not to all) as it reasonably determines to be necessary or appropriate to reduce or eliminate any amount that may otherwise be taken into account as a Liquidation Adjustment pursuant to Section 4.1.

3.2 Sale of Partnership. If a sale of the Partnership is structured as a direct or indirect disposition of Partnership Interests, whether by a sale of Partnership Interests, merger, consolidation or otherwise, the purchase or other agreement governing such disposition shall contain provisions, which replicate, and each Partner agrees to apportion the proceeds among the Partners to replicate, to the maximum extent possible, the economic result that would have been attained under Section 3.1 had the sale been structured as a sale of the Partnership’s assets and a distribution of the net proceeds thereof after transaction expenses related to such sale. For the avoidance of doubt, this Section 3.2 is not applicable to any of the Reorganization Transactions or the IPO.

3.3 Tax Distributions. Notwithstanding Section 3.1, the Partnership shall, to the extent of available cash, make distributions:

3

(a) To each Partner in amounts intended to enable such Partner (or any person whose tax liability is determined by reference to the income of any such Partner) to discharge its U.S. federal, state and local (and, as the General Partner shall determine, non-U.S.) tax liabilities arising from allocations made (or to be made) and any distributions made pursuant to this Section 3.3 (“Tax Distributions”). The amount of each Tax Distribution shall be determined by the General Partner, taking into account the maximum combined U.S. federal, New York State and New York City tax rate applicable to individuals on ordinary income and capital gain (taking into account the applicable holding period), as the case may be, the amounts of ordinary income and capital gain (including amounts subject to tax at capital gain rates under Section 1(h)(11) of the Code) allocated to the Partners pursuant to this Agreement, and otherwise based on such reasonable assumptions as the General Partner determines in good faith to be appropriate, provided that the net taxable income allocated to the Partners shall be determined without taking into account adjustments to basis pursuant to Section 743(b) of the Code. Tax Distributions made pursuant to the foregoing shall be treated as advances against subsequent distributions payable to the applicable Partner pursuant to Section 3.1 or Section 4.1, as the case may be.

(b) To the General Partner in amounts intended to enable the General Partner to satisfy its payment obligations under the Continuing Limited Partners Tax Receivable Agreement and the Former Limited Partners Tax Receivable Agreement (“TRA Distributions”). TRA Distributions shall be treated as advances against subsequent distributions payable to the General Partner pursuant to Section 3.1 or Section 4.1, as the case may be.

3.4 Limitations on Distributions. Notwithstanding any other provision of this Agreement, the Partnership shall not make a distribution to a Partner on account of its interest in the Partnership if such distribution would violate the Act or other applicable law.

ARTICLE IV

LIQUIDATION, TERMINATION AND DISSOLUTION

4.1 Winding Up and Dissolution.

(a) The Partnership shall dissolve, and its affairs shall be wound up, at such time as (i) the General Partner of the Partnership approves in writing, (ii) an event of withdrawal of the General Partner has occurred under the Act (unless the Partnership is continued without dissolution in accordance with this Agreement or the Act), (iii) an entry of a decree of judicial dissolution has occurred under Section 17-802 of the Act or (iv) the Partnership does not have a Limited Partner (unless the Partnership is continued without dissolution in accordance with the Act); provided, however, that the Partnership shall not be dissolved or required to be wound up upon an event of withdrawal of the General Partner described in Section 4.1(b) hereof if (x) at the time of such event of withdrawal, there is at least one (1) other General Partner of the Partnership who carries on the business of the Partnership (any remaining General Partner being hereby authorized to carry on the business of the Partnership) or (y) within ninety (90) days after the occurrence of such event of withdrawal, all remaining Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of the event of withdrawal, of one (1) or more additional general partners of the Partnership. For the avoidance of doubt, none of the Reorganization Transactions (including any general partner ceasing to be a general partner of the Partnership) resulted in the dissolution of the Partnership, and the Partnership is hereby continued without dissolution.

4

(b) Upon dissolution of the Partnership pursuant to this Agreement and the Act, the General Partner, or if there is none, a Person selected by the Partners holding a majority of the Partnership Interests to act as a liquidating trustee (the “Liquidating Trustee”), shall wind up the affairs of the Partnership and proceed within a reasonable period of time to sell or otherwise liquidate all of the assets of the Partnership, after paying or making due provisions by the setting up of reserves or otherwise for all liabilities to creditors of the Partnership, and to distribute the assets among the Partners in accordance with the provisions of this Agreement. Within a reasonable time after the effective date of the commencement of the winding up of the Partnership, the assets of the Partnership, or proceeds therefrom, shall be distributed or used as follows: (i) first, to the payment and discharge of all of the Partnership’s debts and liabilities (including debts and liabilities to the Partners, to the extent permitted by law) and the expenses of the liquidation and to the setting up of any reserves which the General Partner (or Liquidating Trustee, as applicable) may deem reasonably necessary for any contingent, conditional or unmatured liabilities or obligations of the Partnership and (ii) second, to the Partners, in accordance with Section 3.1. Notwithstanding the foregoing, (x) if, prior to making any distribution to the Partners contemplated under clause (ii), a Partner has received from the Partnership since the date of this Agreement aggregate cumulative distributions pursuant to Section 3.1 and Section 3.3 in an amount that is greater or less than the distributions such Partner would have been entitled to receive if all previous distributions were made to the Partners pursuant to Section 3.1(a) (such excess or deficit, a “Liquidation Adjustment”), the General Partner shall make such adjustments to the amounts distributable to the Partners under clause (ii) as the General Partner determines necessary in its reasonable discretion to ensure that the cumulative distributions to the Partners since the date of this Agreement is consistent with Section 3.1(a).

(c) In the event of dissolution of the Partnership, the Partners shall execute, do or concur in all necessary or proper instruments, acts, matters and things for realizing the outstanding debts of the Partnership and for dividing the surplus assets between the Partners as herein provided and for notifying the winding up and dissolution of the Partnership to Persons having had dealings with the Partnership.

ARTICLE V

RESTRICTIONS ON TRANSFER

5.1 Restrictions on Transfer.

(a) Each Partner, and its respective Transferees, shall be permitted to Transfer its Partnership Interests, including pursuant to Exchange Transactions, subject to compliance with this Agreement, the Management Subscription Agreements, the Management Partner LLC Agreement and any applicable lock-up agreements then in effect.

5

(b) Notwithstanding anything otherwise to the contrary in this Section 5.1, each Partner may Transfer any LP Partnership Interests in Exchange Transactions pursuant to, and in accordance with, the Exchange Agreement; provided that in the case of any Partners other than the CD&R Partner, such Exchange Transaction shall be effected in compliance with reasonable policies that the General Partner may adopt or promulgate from time to time (including policies requiring the use of designated administrators or brokers) in its sole discretion. Any transferee of such LP Partnership Interests pursuant to the Exchange Agreement shall automatically be admitted as a substitute Limited Partner with respect to such LP Partnership Interests notwithstanding any other provision of this Agreement to the contrary.

(c) The General Partner may in its sole discretion at any time and from time to time, without the consent of any Partner or other Person, cause to be Transferred in an Exchange Transaction any and all LP Partnership Interests, except for LP Partnership Interests held by the CD&R Partner and/or in which the CD&R Partner has an indirect interest as set forth in the books and records of the Partnership or the CD&R Partner. Any such determinations by the General Partner need not be uniform and may be made selectively among Partners, whether or not such Partners are similarly situated. In addition, the General Partner may, with the consent of the CD&R Partner and the consent of Partners holding at least 66 2/3% of the outstanding LP Partnership Interests, require all Partners to Transfer in an Exchange Transaction all LP Partnership Interests held by them; provided that the prior written consent of the CD&R Partner will be required.

5.2 Overriding Provisions. Notwithstanding any contrary provision in this Agreement, in no event may any Partner Transfer all or a portion of such Partner’s Partnership Interests if the General Partner determines such Transfer would pose a material risk that the Partnership would be treated as a “publicly traded partnership” within the meaning of 7704 of the Code; provided, however, that a Transfer will not be prohibited on this basis so long as the Partnership satisfies the “private placements” safe harbor under Section 1.7704-1(h) of the Treasury Regulations. In addition, none of the Partnership Interests may be Transferred if such Transfer would result in the Partnership becoming subject to the reporting requirements of Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended (or other similar provision of non-U.S. law). To the fullest extent permitted by law, any purported Transfer in violation of this Section 5.2 shall be void ab initio. For the avoidance of doubt, this Section 5.2 and Section 5.1 do not apply to any Transfers of LP Partnership Interests or GP Partnership Interests pursuant to or in connection with the Reorganization Transactions (all such Transfers being hereby ratified, approved and confirmed in all respects).

ARTICLE VI

ARTICLE VIII

LIABILITY, EXCULPATION AND INDEMNIFICATION

8.1 Liability. Except as otherwise provided by the Act, the debts, obligations and liabilities of the Partnership, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Partnership, and no Covered Person (other than the General Partner) shall be obligated personally for any such debt, obligation or liability of the Partnership solely by reason of being a Covered Person.

8.2 Exculpation. To the fullest extent permitted by applicable Law, no Covered Person shall be liable to the Partnership or any Person bound by this Agreement for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Covered Person in good faith on behalf of the Partnership and in a manner believed to be within the scope of authority conferred on such Covered Person by this Agreement, except that a Covered Person shall be liable for any such loss, damage or claim incurred by reason of such Covered Person’s Disabling Conduct. To the fullest extent permitted by applicable Law, each Covered Person shall in the performance of his or her duties be fully protected in relying in good faith upon the records of the Partnership and upon information, opinions, reports or statements presented to the Partnership by any Officers or employees of the Partnership, or committees

10

designated by the General Partner, or by any other Person as to the matters the Covered Person reasonably believes are within such other Person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Partnership. Without limiting the foregoing, each Limited Partner agrees to waive, to the fullest extent permitted by applicable Law, any claim or right of action it might have, whether individually or on behalf of the Partnership, against the General Partner or any director of the General Partner on account of any action taken or failure to take any action in its, his or her capacity as a director of the General Partner; provided that such waiver shall not extend to any matter involving any actual fraud or dishonesty on the part of such director.

8.3 Fiduciary Duty; Partnership Opportunities.

(a) Waiver of Fiduciary Duties. Subject to the proviso in the last sentence of Section 8.2, any duties (including fiduciary duties) of a Covered Person to the Partnership, to any Partner or to any other Person bound by this Agreement that would otherwise apply at law or in equity are hereby eliminated to the fullest extent permitted under the Act and any other applicable Law, and each Partner waives to the fullest extent permitted by the Act and any other applicable Law, any duty that a Covered Person may have to the Partnership or any other Partner that would otherwise apply at law or in equity, to the extent such waiver is necessary to give effect to the terms of this Section 8.3(a); provided that the foregoing shall not eliminate (i) the obligation of each Covered Person to act in compliance with the express terms of this Agreement or (ii) the implied contractual covenant of good faith and fair dealing in construing this Agreement. A Covered Person acting under this Agreement shall not be liable to the Partnership or to any other Person bound by this Agreement for its good faith reliance on the provisions of this Agreement. Without limiting the generality of the foregoing, to the fullest extent permitted by applicable Law, to the extent that, at law or in equity, a Covered Person has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to any other Covered Person, a Covered Person acting under this Agreement shall not be liable to the Partnership or to any Partner or to any other Person bound by this Agreement for its good faith reliance on the provisions of this Agreement.

(b) Partnership Opportunities. Except as otherwise provided in the last sentence of this Section 8.3(b), to the fullest extent permitted by applicable Law, (i) no Covered Person shall have any duty to communicate or present an investment or business opportunity or prospective economic advantage to the Partnership or any of its Subsidiaries in which the Partnership or one of its Subsidiaries may, but for the provisions of this Section 8.3(b), have an interest or expectancy (“Partnership Opportunity”), and (ii) no Covered Person will be deemed to have breached any fiduciary or other duty or obligation to the Partnership, any Partner or any other Person bound by this Agreement by reason of the fact that any such Person pursues or acquires a Partnership Opportunity for itself or its Affiliates or directs, sells, assigns or transfers such Partnership Opportunity to another Person or does not communicate information regarding such Partnership Opportunity to the Partnership or any applicable Subsidiary. The Partnership, on behalf of itself and its Subsidiaries, renounces any interest in a Partnership Opportunity and any expectancy that a Partnership Opportunity will be offered to the Partnership; provided, however, that the Partnership does not renounce any interest or expectancy it may have in any Partnership Opportunity that is offered to an Officer or employee of the Partnership or any of its Subsidiaries, (x) who is not a director, officer or employee of a Partner, or (y) who is also a director, officer or employee of a Partner, if, in the case of clause (y), such opportunity is expressly offered to such Person in his or her capacity as an Officer or employee of the Partnership or any of its Subsidiaries, and the Partners recognize that the Partnership reserves such rights.

11

(c) Overriding Provision. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities of a Covered Person to the Partnership, any Partner or any other Person bound by this Agreement otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties and liabilities of such Covered Person to the fullest extent permitted by applicable law.

8.4 Insurance and Indemnification. In addition to the payment of expenses pursuant to Section 8.5, to the fullest extent permitted by applicable Law, the Partnership agrees to indemnify, pay and hold each Covered Person harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including any interest and penalties, out-of-pocket expenses, and the fees and disbursements of counsel for such Covered Person in connection with any investigative, administrative or judicial proceedings, whether or not such Covered Person shall be designated a party thereto), whether absolute, accrued, conditional or otherwise and whether or not resulting from third-party claims, which may be imposed on, incurred by or asserted against any such Covered Person, in any manner relating to or arising out of any act or omission performed or omitted by such Covered Person on behalf of the Partnership, except that no Covered Person shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such Covered Person which is determined by a final, non-appealable decision of a court of competent jurisdiction to have resulted from such Covered Person’s Disabling Conduct; provided that any indemnity under this Section 8.4 shall be provided out of and to the extent of Partnership assets only, and no Covered Person shall have any personal liability on account thereof.

12

8.6 Severability; Third Party Rights. To the fullest extent permitted by applicable Law, if any portion of this Article VIII shall be invalidated on any ground by any court of competent jurisdiction, then the Partnership shall nevertheless indemnify each Covered Person and may indemnify each employee or agent of the Partnership as to costs, charges and expenses (including reasonable attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the Partnership, in each case to the fullest extent permitted by any applicable portion of this Article VIII that shall not have been invalidated. A Person who is not a party to this Agreement may not, in its own right or otherwise, enforce any term of this Agreement.

ARTICLE IX

CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS; ALLOCATIONS

9.1 Capital Contributions.

(a) Capital Contributions. Each Partner that has made (or is deemed to have made) capital contributions to the Partnership shall have such capital contributions reflected in its Capital Account. No Partner shall have any obligation to make any capital contributions or other contributions to the Partnership. Except as otherwise set forth in this Agreement, no interest shall accrue on any capital contribution, and no Partner shall have the right to withdraw or be repaid any capital contribution.

(b) Additional Capital Contributions. No Limited Partner shall be required to make any additional capital contribution or loan in respect of the Partnership Interests then owned by any such Limited Partner. However, a Limited Partner may make additional capital contributions to the Partnership with, and only with, the written consent of the General Partner and such Limited Partner and in compliance with the other terms and conditions set forth in this Agreement.

9.2 Capital Accounts, Adjustments, Allocation of Book Income and Loss.

(a) Capital Accounts. There shall be established on the books and records of the Partnership a capital account (a “Capital Account”) for each Partner. The Capital Accounts are intended to comply with Treasury Regulations § 1.704-1(b) and shall be interpreted and applied in a manner consistent with such regulations.

(b) Adjustments. Subject to Section 4.1, as of the last day of each Accounting Period, the balance in each Partner’s Capital Account shall be adjusted by: (i) increasing such balance by (A) such Partner’s allocable share of each item of the Partnership’s income and gain for such Accounting Period (allocated in accordance with Section 4.1(b)) and (B) the amount of any cash and the fair market value of any property (net of the amount of any liabilities to which such property is subject) contributed by such Partner during such Accounting Period and (ii) decreasing such balance by (A) such Partner’s allocable share of each item of the Partnership’s loss and deduction for such Accounting Period (allocated in accordance with

13

Section 4.1(b)) and (B) the amount of cash or the fair market value of any property (net of the amount of any liabilities to which such property is subject) distributed to such Partner during such Accounting Period. Each Partner’s Capital Account shall be further adjusted with respect to any special allocations or adjustments made pursuant to this Agreement or otherwise determined by the General Partner to be necessary or appropriate under the circumstances.

(c) Allocation of Book Income and Loss. Except as otherwise provided herein, each item of income, gain, loss or deduction of the Partnership (determined in accordance with U.S. tax principles as applied to the maintenance of capital accounts) shall be allocated among the Capital Accounts of the Partners with respect to each Accounting Period, as of the end of such Accounting Period, in such a manner that as closely as possible gives economic effect to the provisions of this Agreement, taking into account the Partners’ varying interests in the Partnership during the relevant year, including in connection with the Original Agreement and the A&R Agreement.

9.3 Tax Allocations; Other Tax Matters.

(a) Tax Allocations. The income, gains, losses, credits and deductions recognized by the Partnership shall be allocated among the Partners, for U.S. federal, state and local income tax purposes, to the extent permitted under the Code and the Treasury Regulations, in the same manner that each such item is allocated to the Partners’ Capital Accounts in accordance with Section 9.2(c) or as otherwise expressly provided herein. Notwithstanding the foregoing, the General Partner may adjust such allocations for U.S. federal, state and local tax purposes so long as such adjusted allocations have substantial economic effect or are in accordance with the Partners’ interest in the Partnership, in each case within the meaning of the Code and the Treasury Regulations. 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 Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such property to the Partnership for U.S. federal income tax purposes and its fair market value at the time of contribution. Tax credits and tax credit recapture shall be allocated in accordance with the interests of the Partners in the Partnership as provided in Treasury Regulations § 1.704-1(b)(4)(ii). All matters concerning allocations for U.S. federal, state and local and non-U.S. income tax purposes, including accounting procedures, not expressly provided for by the terms of this Agreement shall be determined by the General Partner in its sole discretion.

(b) Withholding Generally. Each Partner shall, to the fullest extent permitted by applicable Law, indemnify and hold harmless the Partnership and each Person who is or who is deemed to be the responsible withholding agent for U.S. federal, state or local or non-U.S. income tax purposes against all claims, liabilities and expenses of whatever nature relating to such Person’s obligation to withhold and to pay over, or otherwise pay, any withholding or other taxes payable by the Partnership with respect to such Partner or as a result of such Partner’s participation in the Partnership.

14

(c) Authority to Withhold; Treatment of Withheld Tax. Notwithstanding any other provision of this Agreement, each Partner hereby authorizes the Partnership and the General Partner to withhold and to pay over, or otherwise pay, any withholding or other taxes payable or required to be deducted by the Partnership attributable to such Partner (including taxes attributable to income or gain allocable to such Partner) or resulting from such Partner’s participation in the Partnership. If and to the extent that the Partnership shall be required to withhold or pay any such withholding or other taxes, such Partner shall be deemed for all purposes of this Agreement to have received a payment from the Partnership as of the time such withholding or other taxes are withheld or required to be paid, whichever is earlier, which payment shall be deemed to be a distribution with respect to such Partner’s interest in the Partnership to the extent that such Partner (or any successor to such Partner’s interest in the Partnership) would have received a cash distribution but for such withholding or other taxes. To the extent that such payment exceeds the cash distribution that such Partner would have received but for such withholding, the General Partner shall notify such Partner as to the amount of such excess and such Partner shall make a prompt payment to the Partnership of such amount by wire transfer, which payment shall not constitute a capital contribution and, consequently, shall not increase the Capital Account of such Partner. For the avoidance of doubt, references to taxes in this Agreement include interest, penalties and additions to tax.

(d) Withholding from Distributions to the Partnership. In the event that the Partnership receives a distribution or payment from or in respect of which tax has been withheld or other taxes have been paid, the Partnership shall be deemed to have received cash in an amount equal to the amount of such withholding or other taxes, and each Partner shall be deemed for all purposes of this Agreement to have received a payment from the Partnership as of the time of such distribution or payment equal to the portion of such amount that is attributable to such Partner’s interest in the Partnership (or attributable to income allocable to such Partner) as determined by the General Partner in its sole discretion, which payment shall be deemed to be a distribution to such Partner pursuant to Section 3.1 to the extent that such Partner (or any successor to such Partner’s interest in the Partnership) would have received a cash distribution but for such withholding or other taxes. To the extent that such payment exceeds the cash distribution that such Partner would have received but for such withholding, the General Partner shall notify such Partner as to the amount of such excess and such Partner shall make a prompt payment to the Partnership of such amount by wire transfer, which payment shall not constitute a capital contribution and, consequently, shall not increase the Capital Account of such Partner.

(e) Withholding Forms and Information. Each Partner shall furnish the Partnership with any information, representations and forms as shall reasonably be requested by the Partnership from time to time to assist it in complying with any applicable Law or tax requirements or determining the extent of, and in fulfilling, any withholding obligations in respect of the Partnership. Each Partner shall furnish the Partnership with any information, representations and forms as shall reasonably be requested by the Partnership to assist it in obtaining any exemption, reduction or refund of any withholding or other taxes imposed by any taxing authority or other governmental agency upon the Partnership or amounts paid, or allocable, to the Partnership.

(f) Tax Elections. The General Partner shall (and is hereby authorized to) cause the Partnership and, if applicable, any subsidiary of the Partnership to make a timely election under Section 754 of the Code, or any similar provision enacted in lieu thereof, and any similar provisions under any state, local or non-U.S. tax law. The General Partner shall have the power to make any other election on behalf of the Partnership that the General Partner deems appropriate in its sole discretion.

15

(g) Tax Representative. The General Partner shall designate a Person as the “partnership representative” of the Partnership for each taxable year of the Partnership, in accordance with Section 6223 of the Code and any similar provision under any state or local or non-U.S. tax laws (such Person with respect to any taxable year, the “Tax Representative”). Each Partner hereby consents to each such designation and agrees that, upon the request of the General Partner, such Partner will execute, certify, acknowledge, deliver, swear to, file and record at the appropriate public offices such documents as may be necessary or appropriate to evidence such consent. No Limited Partner may revoke any designation of a Tax Representative. The applicable Tax Representative shall have the sole discretion to determine all matters, and shall be authorized to take any actions necessary, with respect to preparing and filing any U.S. federal, state or local or non-U.S. tax return of the Partnership and any audit, examination or investigation (including any judicial or administrative proceeding) of the Partnership by any U.S. federal, state or local or non-U.S. taxing authority (including the allocation of any resulting taxes, penalties and interest among the Partners and whether to make an election under Section 6226 of the Code or any similar provision of any state or local tax laws with respect to any audit or other examination of the Partnership). Each Partner shall promptly upon request furnish to any Tax Representative any information that such Tax Representative may reasonably request in connection with (i) preparing or filing any tax returns of the Partnership, (ii) any tax election of the Partnership or (iii) any audit, examination or investigation (including any judicial or administrative proceeding) of the Partnership. If the applicable Tax Representative makes an election under Section 6226 of the Code or any similar provision of any state or local tax laws with respect to any audit adjustment of any item of the Partnership’s income, gain, loss, deduction or credit (or adjustment of the allocation of any such items among the Partners), each Partner shall comply with the requirements set forth in Section 6226 of the Code or any similar provision of any state or local or non-U.S. tax laws (and any applicable guidance issued by the applicable taxing authority) with respect to such election. Each Partner shall file all U.S. tax returns with respect to such Partner’s distributive share of any item of the Partnership’s income, gain, loss, deduction or credit in a manner consistent with the Partnership’s U.S. tax treatment of such item. For the avoidance of doubt, any taxes, penalties or interest imposed on the Partnership with respect to any audit, examination or investigation (including any judicial or administrative proceeding) of the Partnership by any taxing authority under Section 6225 of the Code (and any similar provisions under any state or local or non-U.S. tax laws) shall be deemed to be distributions subject to the provisions of Section 3.1. No Partner shall, without the consent of the General Partner, (A) file a request for administrative adjustment of Partnership items, (B) file a petition with respect to any Partnership item or other tax matters involving the Partnership or (C) enter into a settlement agreement with any taxing authority with respect to any Partnership items.

(h) Schedule K-1. The Partnership shall cause the preparation and timely filing of all of the Partnership’s tax returns and shall timely file all other writings required by any governmental authority having jurisdiction to require such filing. Each Partner shall provide such information to the Partnership as may be reasonably necessary for purposes of the Partnership’s preparing any such required tax return or information return. The General Partner shall use commercially reasonable efforts to provide to each Partner any information or relevant

16

form, including but not limited to Internal Revenue Service Schedule K-1 to Internal Revenue Service Form 1065, regarding the Partnership’s taxable income or loss and each item of income, gain, loss, deduction or credit which is relevant to reporting a Partner’s share of the Partnership’s income, gain, loss, deduction or credit for income tax purposes, as soon as practicable after the close of the Partnership’s Tax Year (as defined below). Upon the written request of any Partner, the Partnership shall provide any information reasonably necessary for (i) the preparation of any U.S. federal, state, local and non-U.S. tax returns which may need to be filed by such Partner or (ii) financial accounting purposes.
