Any number of offices may be held by the same person. All employees, agents and officers shall be subject to the supervision and direction of the General Partner and may be removed from such office by the General Partner and the authority, duties or responsibilities of any employee, agent or officer of the Partnership may be suspended by the General Partner from time to time, in each case in the sole discretion of the General Partner.

Section 3.6 Action by Written Consent or Ratification. Any action required or permitted to be taken by the Partners pursuant to this Agreement shall be taken if all Partners whose consent or ratification is required consent thereto or provide a ratification in writing.

ARTICLE IV

DISTRIBUTIONS

Section 4.1 Distributions.

(a) The General Partner, in its sole discretion, may authorize distributions by the Partnership to the Partners, which distributions shall be made pro rata in accordance with the Partners’ respective Vested Percentage Interests. The Partners holding any Unvested Units at the time of a distribution shall be entitled to receive, in connection with any subsequent distribution, in respect of any such Unvested Units that have become vested at the time of such subsequent distribution, a distribution (“Catch-Up Distribution”) in the amount necessary so that the cumulative amount received by the Partners of outstanding Vested Units, after giving effect to such Catch-Up Distribution, is the same as it would have been if all such outstanding Vested Units were outstanding and vested at the time of all earlier distributions under this Section 4.1(a).

(b) (i) In addition to the foregoing, if the General Partner reasonably determines that the taxable income of the Partnership for a Fiscal Year will give rise to taxable income for the Partners (“Net Taxable Income”), the General Partner shall cause the Partnership to distribute Available Cash in respect of income tax liabilities (the “Tax Distributions”) to the extent that other distributions made by the Partnership for such year were otherwise insufficient to cover such tax liabilities. The Tax Distributions payable with respect to any Fiscal Year shall be computed based upon the General Partner’s estimate of the allocable Net Taxable Income in accordance with Article V, multiplied by the Assumed Tax Rate (the “Tax Amount”). For purposes of computing the Tax Amount, the effect of any benefit under Section 743(b) of the Code will be ignored.

(ii) Tax Distributions shall be calculated and paid no later than one day prior to each quarterly due date for the payment by corporations on a calendar

year of estimated taxes under the Code in the following manner (A) for the first quarterly period, 25% of the Tax Amount, (B) for the second quarterly period, 50% of the Tax Amount, less the prior Tax Distributions for the Fiscal Year, (C) for the third quarterly period, 75% of the Tax Amount, less the prior Tax Distributions for the Fiscal Year and (D) for the fourth quarterly period, 100% of the Tax Amount, less the prior Tax Distributions for the Fiscal Year. Following each Fiscal Year, and no later than one day prior to the due date for the payment by corporations of income taxes for such Fiscal Year, the General Partner shall make an amended calculation of the Tax Amount for such Fiscal Year (the “Amended Tax Amount”), and shall cause the Partnership to distribute a Tax Distribution, out of Available Cash, to the extent that the Amended Tax Amount so calculated exceeds the cumulative Tax Distributions previously made by the Partnership in respect of such Fiscal Year. If the Amended Tax Amount is less than the cumulative Tax Distributions previously made by the Partnership in respect of the relevant Fiscal Year, then the difference (the “Credit Amount”) shall be applied against, and shall reduce, the amount of Tax Distributions made for subsequent Fiscal Years. Within 30 days following the date on which the Partnership files a tax return on Form 1065, the General Partner shall make a final calculation of the Tax Amount of such Fiscal Year (the “Final Tax Amount”) and shall cause the Partnership to distribute a Tax Distribution, out of Available Cash, to the extent that the Final Tax Amount so calculated exceeds the Amended Tax Amount. If the Final Tax Amount is less than the Amended Tax Amount in respect of the relevant Fiscal Year, then the difference (the “Additional Credit Amount”) shall be applied against, and shall reduce, the amount of Tax Distributions made for subsequent Fiscal Years. Any Credit Amount and Additional Credit Amount applied against future Tax Distributions shall be treated as an amount actually distributed pursuant to this Section 4.1(b) for purposes of the computations herein.

(iii) Tax Distributions to a Partner (other than the portion of any Tax Distribution with respect to any of the Units that are forfeited, cancelled or terminated in accordance with the terms and conditions of this Agreement) shall be offset against and reduce subsequent distributions (other than Tax Distributions) to which a Partner would otherwise be entitled to receive pursuant to Section 4.1(a) and/or Section 9.3(b).

Section 4.2 Liquidation Distribution. Distributions made upon dissolution of the Partnership shall be made as provided in Section 9.3.

Section 4.3 Limitations on Distribution. Notwithstanding any provision to the contrary contained in this Agreement, the General Partner shall not make a Partnership distribution to any Partner if such distribution would violate Section 17-607 of the Act or other applicable Law.

ARTICLE V

CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS;

TAX ALLOCATIONS; TAX MATTERS

Section 5.1 Initial Capital Contributions. The Partners have made, on or prior to the date hereof, Capital Contributions and have acquired the number of Class A Units as specified in the books and records of the Partnership.

Section 5.2 No Additional Capital Contributions. Except as otherwise provided in this Article V, no Partner shall be required to make additional Capital Contributions to the Partnership without the consent of such Partner or permitted to make additional Capital Contributions to the Partnership without the consent of the General Partner.

Section 5.3 Capital Accounts. A separate capital account (a “Capital Account”) shall be established and maintained for each Partner in accordance with the provisions of Treasury Regulations Section 1.704-1(b)(2)(iv). The Capital Account of each Partner shall be credited with such Partner’s Capital Contributions, if any, all Profits allocated to such Partner pursuant to Section 5.4 and any items of income or gain which are specially allocated pursuant to Section 5.5; and shall be debited with all Losses allocated to such Partner pursuant to Section 5.4, any items of loss or deduction of the Partnership specially allocated to such Partner pursuant to Section 5.5, and all cash and the Carrying Value of any property (net of liabilities assumed by such Partner and the liabilities to which such property is subject) distributed by the Partnership to such Partner. Any references in any section of this Agreement to the Capital Account of a Partner shall be deemed to refer to such Capital Account as the same may be credited or debited from time to time as set forth above. In the event of any transfer of any interest in the Partnership in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of the transferor to the extent it relates to the transferred interest.

Section 5.4 Allocations of Profits and Losses. Except as otherwise provided in this Agreement, Profits and Losses (and, to the extent necessary, individual items of income, gain or loss or deduction of the Partnership) shall be allocated in a manner such that the Capital Account of each Partner after giving effect to the Special Allocations set forth in Section 5.5 is, as nearly as possible, equal (proportionately) to (i) the distributions that would be made pursuant to Article IV if the Partnership were dissolved, its affairs wound up and its assets sold for cash equal to their Carrying Value, all Partnership liabilities were satisfied (limited with respect to each non-recourse liability to the Carrying Value of the assets securing such liability) and the net assets of the Partnership were distributed to the Partners pursuant to this Agreement, minus (ii) such Partner’s share of Partnership Minimum Gain and Partner Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets. For purposes of this Article V, each Unvested Unit shall be treated as a Vested Unit. Notwithstanding the foregoing, the General Partner shall make such adjustments to

Capital Accounts as it determines in its sole discretion to be appropriate to ensure allocations are made in accordance with a partner’s interest in the Partnership.

Section 5.5 Special Allocations. Notwithstanding any other provision in this Article V:

(a) Minimum Gain Chargeback. If there is a net decrease in Partnership Minimum Gain or Partner Nonrecourse Debt Minimum Gain (determined in accordance with the principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during any Partnership taxable year, the Partners shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The items to be so allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section 5.5(a) is intended to comply with the minimum gain chargeback requirements in such Treasury Regulations Sections and shall be interpreted consistently therewith; including that no chargeback shall be required to the extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4).

(b) Qualified Income Offset. If any Partner unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate the deficit balance in such Partner’s Adjusted Capital Account Balance created by such adjustments, allocations or distributions as promptly as possible; provided that an allocation pursuant to this Section 5.5(b) shall be made only to the extent that a Partner would have a deficit Adjusted Capital Account Balance in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if this Section 5.5(b) were not in this Agreement. This Section 5.5(b) is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith.

(c) Gross Income Allocation. If any Partner has a deficit Capital Account at the end of any Fiscal Year which is in excess of the sum of (i) the amount such Partner is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations Section 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible; provided that an allocation pursuant to this Section 5.5(c) shall be made only if and to the extent that a Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if Section 5.5(b) and this Section 5.5(c) were not in this Agreement.

(d) Nonrecourse Deductions. Nonrecourse Deductions shall be allocated to the Partners in accordance with their respective Total Percentage Interests.

(e) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated to the Partner who bears the economic risk of loss with respect to the liability to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulations Section 1.704-2(j).

(f) Creditable Non-U.S. Taxes. Creditable Non-U.S. Taxes for any taxable period attributable to the Partnership, or an entity owned directly or indirectly by the Partnership, shall be allocated to the Partners in proportion to the Partners’ distributive shares of income (including income allocated pursuant to Section 704(c) of the Code) to which the Creditable Non-U.S. Tax relates (under principles of Treasury Regulations Section 1.904-6). The provisions of this Section 5.5(f) are intended to comply with the provisions of Treasury Regulations Section 1.704-1(b)(4)(viii), and shall be interpreted consistently therewith.

(g) Ameliorative Allocations. Any special allocations of income or gain pursuant to Section 5.5(b) or 5.5(c) shall be taken into account in computing subsequent allocations pursuant to Section 5.4 and this Section 5.5(g), so that the net amount of any items so allocated and all other items allocated to each Partner shall, to the extent possible, be equal to the net amount that would have been allocated to each Partner if such allocations pursuant to Section 5.5(b) or 5.5(c) had not occurred.

Section 5.6 Tax Allocations. For income tax purposes, each item of income, gain, loss and deduction of the Partnership shall be allocated among the Partners in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided that in the case of any asset the Carrying Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated solely for income tax purposes in accordance with the principles of Sections 704(b) and (c) of the Code (in any manner determined by the General Partner and permitted by the Code and Treasury Regulations) so as to take account of the difference between Carrying Value and adjusted basis of such asset. Notwithstanding the foregoing, the General Partner shall make such allocations for tax purposes as it determines in its sole discretion to be appropriate to ensure allocations are made in accordance with a Partner’s interest in the Partnership.

Section 5.7 Tax Advances. To the extent the General Partner reasonably believes that the Partnership is required by law to withhold or to make tax payments on behalf of or with respect to any Partner or the Partnership is subjected to tax itself by reason of the status of any Partner (“Tax Advances”), the General Partner may withhold such amounts and make such tax payments as so required. All Tax Advances made on behalf of a Partner shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Partner or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Partner. For all purposes of this Agreement, such Partner shall be treated as having received the amount of the distribution that is equal to the Tax Advance. Each Partner shall indemnify and hold

harmless the Partnership and the other Partners from and against any liability (including, without limitation, any liability for taxes, penalties, additions to tax or interest other than any penalties, additions to tax or interest imposed as a result of the Partnership’s failure to withhold or make a tax payment on behalf of such Partner which withholding or payment is required pursuant to applicable Law but only to the extent amounts sufficient to pay such taxes were not timely distributed to the Partner pursuant to Section 4.1(b)) with respect to income attributable to or distributions or other payments to such Partner.

Section 5.8 Tax Matters. The General Partner shall be the initial “tax matters partner” within the meaning of Section 6231(a)(7) of the Code (the “Tax Matters Partner”). The Partnership shall file as a partnership for federal, state, provincial and local income tax purposes, except where otherwise required by Law. All elections required or permitted to be made by the Partnership, and all other tax decisions and determinations relating to federal, state, provincial or local tax matters of the Partnership, shall be made by the Tax Matters Partner, in consultation with the Partnership’s attorneys and/or accountants. Tax audits, controversies and litigations shall be conducted under the direction of the Tax Matters Partner. The Tax Matters Partner shall keep the other Partners reasonably informed as to any tax actions, examinations or proceedings relating to the Partnership and shall submit to the other Partners, for their review and comment, any settlement or compromise offer with respect to any disputed item of income, gain, loss, deduction or credit of the Partnership. As soon as reasonably practicable after the end of each Fiscal Year, the Partnership shall send to each Partner a copy of U.S. Internal Revenue Service Schedule K-1, and any comparable statements required by applicable U.S. state or local income tax Law as a result of the Partnership’s activities or investments, with respect to such Fiscal Year. The Partnership also shall provide the Partners with such other information as may be reasonably requested for purposes of allowing the Partners to prepare and file their own tax returns.

Section 5.9 Other Allocation Provisions. Certain of the foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such regulations. Sections 5.3, 5.4 and 5.5 may be amended at any time by the General Partner if necessary, in the opinion of tax counsel to the Partnership, to comply with such regulations or any applicable Law, so long as any such amendment does not materially change the relative economic interests of the Partners.

(i) a copy of the Certificate and this Agreement and all amendments thereto, together with a copy of the executed copies of all powers of attorney pursuant to which the Certificate and this Agreement and all amendments thereto have been executed; and

(ii) promptly after their becoming available, copies of the Partnership’s federal, state and local income tax returns and reports, if any, for the three most recent years.

(c) The General Partner may keep confidential from the Limited Partners, for such period of time as the General Partner determines in its sole discretion, (i) any information that the General Partner reasonably believes to be in the nature of trade secrets or (ii) other information the disclosure of which the General Partner believes is not in the best interests of the Partnership, could damage the Partnership or its business or that the Partnership is required by law or by agreement with any third party to keep confidential.

ARTICLE VII

PARTNERSHIP UNITS

Section 7.1 Units. Interests in the Partnership shall be represented by Units. The Units initially are comprised of one Class: Class A Units. The General Partner may establish, from time to time in accordance with such procedures as the General Partner shall determine from time to time, other Classes, one or more series of any such Classes, or other Partnership securities with such designations, preferences, rights, powers and duties (which may be senior to existing Classes and series of Units or other Partnership securities), as shall be determined by the General Partner, including (i) the right to share in Profits and Losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Units or other Partnership securities (including sinking fund provisions); (v) whether such Unit or other Partnership security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Unit or other Partnership security will be issued, evidenced by certificates and assigned or transferred; (vii) the method for determining the Total Percentage Interest as to such Units or other Partnership securities; and (viii) the right, if any, of the holder of each such Unit or other Partnership security to vote on Partnership matters, including matters relating to the relative designations, preferences, rights, powers and duties of such Units or other Partnership securities.

be established in accordance with this Agreement. All Units of a particular Class shall have identical rights in all respects as all other Units of such Class, except in each case as otherwise specified in this Agreement.

Section 7.2 Register. The register of the Partnership shall be the definitive record of ownership of each Unit and all relevant information with respect to each Partner. Unless the General Partner shall determine otherwise, Units shall be uncertificated and recorded in the books and records of the Partnership.

Section 7.3 Registered Partners. The Partnership shall be entitled to recognize the exclusive right of a Person registered on its records as the owner of Units for all purposes and shall not be bound to recognize any equitable or other claim to or interest in Units on the part of any other Person, whether or not it shall have express or other notice thereof, except as otherwise provided by the Act or other applicable Law.

Any such determination in the General Partner’s discretion in respect of Initial Unvested Units shall be final and binding.

Immediately upon the forfeiture of any Initial Unvested Units, such Unvested Units that have been so forfeited shall be cancelled.

(b) Except as otherwise agreed to in writing between the General Partner and the applicable Limited Partner and reflected in the books and records of the Partnership, (i) if a Limited Partner that is or was at any time an Employed Limited Partner breaches any Restrictive Covenant to which such Limited Partner is subject or (ii) if an Employed Limited Partner is terminated for Cause, the Initial Units held by such Limited Partner at that time (whether or not vested) shall be immediately forfeited without any consideration, and such Limited Partner shall cease to own or have any rights with respect to such Initial Units.

Any such determination in the General Partner’s discretion in respect of Units shall be final and binding. Such determinations need not be uniform and may be made selectively among Limited Partners, whether or not such Limited Partners are similarly situated, and shall not constitute the breach of any duty hereunder or otherwise existing at law, in equity or otherwise.

Consent of the General Partner shall be withheld until the holder of the Encumbrance acknowledges the terms and conditions of this Agreement. Any purported Encumbrance that is not in accordance with this Agreement shall be, to the fullest extent permitted by law, null and void.

Section 8.6 Further Restrictions. Notwithstanding any contrary provision in this Agreement, in no event may any Transfer of a Unit be made by any Limited Partner or Assignee if:

(a) such Transfer is made to any Person who lacks the legal right, power or capacity to own such Unit;

(b) such Transfer would require the registration of such transferred Unit or of any Class of Unit pursuant to any applicable United States federal or state securities laws (including, without limitation, the Securities Act or the Exchange Act) or other non-U.S securities laws (including Canadian provincial or territorial securities laws) or would constitute a non-exempt distribution pursuant to applicable provincial or state securities laws;

(d) to the extent requested by the General Partner, the Partnership does not receive such legal and/or tax opinions and written instruments (including, without limitation, copies of any instruments of Transfer and such Assignee’s consent to be bound by this Agreement as an Assignee) that are in a form satisfactory to the General Partner, as determined in the General Partner’s sole discretion.

Section 8.7 Rights of Assignees. Subject to Section 8.6, the transferee of any permitted Transfer pursuant to this Article VIII will be an assignee only (“Assignee”), and only will receive, to the extent transferred, the distributions and allocations of income, gain, loss, deduction, credit or similar item to which the Partner which transferred its Units would be entitled, and such Assignee will not be entitled or enabled to exercise any other rights or powers of a Partner, such other rights, and all obligations relating to, or in connection with, such interest in the Partnership remaining with the transferring Partner. The transferring Partner will remain a Partner even if it has transferred all of its Units to one or more Assignees until such time as the Assignee(s) is admitted to the Partnership as a Partner pursuant to Section 8.9.

Section 8.8 Admissions, Withdrawals and Removals.

(b) if required by the General Partner, the General Partner receives written instruments (including, without limitation, copies of any instruments of Transfer and such Assignee’s consent to be bound by this Agreement as a substitute Limited

Partner) that are in a form satisfactory to the General Partner (as determined in its sole discretion);

(c) if required by the General Partner, the General Partner receives an opinion of counsel satisfactory to the General Partner to the effect that such Transfer is in compliance with this Agreement and all applicable Law; and

Section 9.1 No Dissolution. Except as required by the Act, the Partnership shall not be dissolved by the admission of additional Partners or withdrawal of Partners in accordance with the terms of this Agreement. The Partnership may be dissolved, liquidated wound up and terminated only pursuant to the provisions of this Article IX, and the Partners hereby irrevocably waive any and all other rights they may have to cause a dissolution of the Partnership or a sale or partition of any or all of the Partnership assets.

Section 9.2 Events Causing Dissolution. The Partnership shall be dissolved and its affairs shall be wound up upon the occurrence of any of the following events (each, a “Dissolution Event”):

(a) the entry of a decree of judicial dissolution of the Partnership under Section 17-802 of the Act upon the finding by a court of competent jurisdiction that the General Partner (i) is permanently incapable of performing its part of this Agreement, (ii) has been guilty of conduct that is calculated to affect prejudicially the carrying on of the business of the Partnership, (iii) willfully or persistently commits a breach of this Agreement, or (iv) conducts itself in a manner relating to the Partnership or its business such that it is not reasonably practicable for the other Partners to carry on the business of the Partnership with the General Partner;

(b) any event which makes it unlawful for the business of the Partnership to be carried on by the Partners;

(d) any other event not inconsistent with any provision hereof causing a dissolution of the Partnership under the Act; or

(e) the Incapacity or removal of the General Partner or the occurrence of a Disabling Event with respect to the General Partner; provided that the Partnership will not be dissolved or required to be wound up in connection with any of the events specified in this Section 9.2(e) if: (i) at the time of the occurrence of such event there is at least one other general partner of the Partnership who is hereby authorized to, and elects to, carry on the business of the Partnership; or (ii) all remaining Limited Partners consent to or ratify the continuation of the business of the Partnership and the appointment of another general partner of the Partnership, effective as of the event that caused the General Partner to cease to be a general partner of the Partnership, within 120 days following the occurrence of any such event, which consent shall be deemed (and if requested each Limited Partner shall provide a written consent or ratification) to have been given for all Limited Partners if the holders of more than 50% of the Vested Units then outstanding agree in writing to so continue the business of the Partnership.

Section 9.3 Distribution upon Dissolution. Upon dissolution, the Partnership shall not be terminated and shall continue until the winding up of the affairs of the Partnership is completed. Upon the winding up of the Partnership, the General Partner or any other Person designated by the General Partner (the “Liquidation Agent”), shall take full account of the assets and liabilities of the Partnership and shall, unless the General Partner determines otherwise, liquidate the assets of the Partnership as promptly as is consistent with obtaining the fair value thereof. The proceeds of any liquidation shall be applied and distributed in the following order:

(a) First, to the satisfaction of debts and liabilities of the Partnership (including satisfaction of all indebtedness to Partners and/or their Affiliates to the extent otherwise permitted by law), including the expenses of liquidation, and including the establishment of any reserve which the Liquidation Agent shall deem reasonably necessary for any contingent, conditional or unmatured contractual liabilities or obligations of the Partnership (“Contingencies”). Any such reserve may be paid over by the Liquidation Agent to any attorney-at-law, or acceptable party, as escrow agent, to be held for disbursement in payment of any Contingencies and, at the expiration of such period as shall be deemed advisable by the Liquidation Agent for distribution of the balance in the manner hereinafter provided in this Section 9.3; and

(b) The balance, if any, to the Partners in accordance with Section 4.1(a).

Section 9.4 Time for Liquidation. A reasonable amount of time shall be allowed for the orderly liquidation of the assets of the Partnership and the discharge of liabilities to creditors so as to enable the Liquidation Agent to minimize the losses attendant upon such liquidation.

Section 9.5 Termination. The Partnership shall terminate when all of the assets of the Partnership, after payment of or due provision for all debts, liabilities

and obligations of the Partnership, shall have been distributed to the holders of Units in the manner provided for in this Article IX, and the Certificate shall have been cancelled in the manner required by the Act.

Section 9.6 Claims of the Partners. The Partners shall look solely to the Partnership’s assets for the return of their Capital Contributions, and if the assets of the Partnership remaining after payment of or due provision for all debts, liabilities and obligations of the Partnership are insufficient to return such Capital Contributions, the Partners shall have no recourse against the Partnership or any other Partner or any other Person. No Partner with a negative balance in such Partner’s Capital Account shall have any obligation to the Partnership or to the other Partners or to any creditor or other Person to restore such negative balance during the existence of the Partnership, upon dissolution or termination of the Partnership or otherwise, except to the extent required by the Act.

Section 9.7 Survival of Certain Provisions. Notwithstanding anything to the contrary in this Agreement, the provisions of Section 10.2 and Section 11.9 shall survive the termination of the Partnership.

ARTICLE X

LIABILITY AND INDEMNIFICATION

Section 10.1 Liability of Partners.

(a) No Limited Partner shall be liable for any debt, obligation or liability of the Partnership or of any other Partner or have any obligation to restore any deficit balance in its Capital Account solely by reason of being a Partner of the Partnership, except to the extent required by the Act.

(b) This Agreement is not intended to, and does not, create or impose any fiduciary duty on any of the Partners (including, without limitation, the General Partner) or on their respective Affiliates. Further, the Partners hereby waive any and all fiduciary duties that, absent such waiver, may exist at or be implied by Law or in equity, and in doing so, recognize, acknowledge and agree that their duties and obligations to one another and to the Partnership are only as expressly set forth in this Agreement and those required by the Act.

(c) To the extent that, at law or in equity, any Partner (including, without limitation, the General Partner) has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to another Partner, the Partners (including, without limitation, the General Partner) acting under this Agreement will not be liable to the Partnership or to any such other Partner for their good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities relating thereto of any Partner (including, without limitation, the General Partner) otherwise existing at law or in equity, are agreed by the Partners to replace to that extent such other duties and liabilities of the Partners (including, without limitation, the General Partner) relating thereto.

(d) The General Partner may consult with legal counsel, accountants and financial or other advisors and any act or omission suffered or taken by the General Partner on behalf of the Partnership or in furtherance of the interests of the Partnership in good faith in reliance upon and in accordance with the advice of such counsel, accountants or financial or other advisors will be full justification for any such act or omission, and the General Partner will be fully protected in so acting or omitting to act so long as such counsel or accountants or financial or other advisors were selected with reasonable care.

(e) Notwithstanding any other provision of this Agreement or otherwise applicable provision of law or equity, whenever in this Agreement the General Partner is permitted or required to make a decision (i) in its “sole discretion” or “discretion” or under a grant of similar authority or latitude, such General Partner shall be entitled to consider only such interests and factors as it desires, including its own interests, and shall, to the fullest extent permitted by applicable Law, have no duty or obligation to give any consideration to any interest of or factors affecting the Partnership or the Limited Partners, or (ii) in its “good faith” or under another expressed standard, such General Partner shall act under such express standard and shall not be subject to any other or different standards.

Section 10.2 Indemnification.

(a) Indemnification. To the fullest extent permitted by law, the Partnership shall indemnify any Person (and such Person’s heirs, executors or administrators) who was or is made or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the Partnership or otherwise), whether civil, criminal, administrative or investigative, and whether formal or informal, including appeals, by reason of the fact that such Person, or a Person for whom such Person was the legal representative, is or was a Partner (including, without limitation, the General Partner) or a director, officer or agent of a Partner (including, without limitation, the General Partner) or the Partnership or, while a director, officer or agent of a Partner (including, without limitation, the General Partner) or the Partnership, is or was serving at the request of the Partnership as a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust, limited liability company, nonprofit entity or other enterprise, for and against all loss and liability suffered and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by such Person or such heirs, executors or administrators in connection with such action, suit or proceeding, including appeals; provided that such Person shall not be entitled to indemnification hereunder only to the extent such Person’s conduct constituted fraud, bad faith or willful misconduct. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.2(c), the Partnership shall be required to indemnify a Person described in such sentence in connection with any action, suit or proceeding (or part thereof) commenced by such Person only if the commencement of such action, suit or proceeding (or part thereof) by such Person was authorized by the General Partner.

(b) Advancement of Expenses. To the fullest extent permitted by law, the Partnership shall promptly pay expenses (including attorneys’ fees) incurred by any Person described in Section 10.2(a) in appearing at, participating in or defending any action, suit or proceeding in advance of the final disposition of such action, suit or proceeding, including appeals, upon presentation of an undertaking on behalf of such Person to repay such amount if it shall ultimately be determined that such Person is not entitled to be indemnified under this Section 10.2 or otherwise. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.2(c), the Partnership shall be required to pay expenses of a Person described in such sentence in connection with any action, suit or proceeding (or part thereof) commenced by such Person only if the commencement of such action, suit or proceeding (or part thereof) by such Person was authorized by the General Partner.

(c) Unpaid Claims. If a claim for indemnification (following the final disposition of such action, suit or proceeding) or advancement of expenses under this Section 10.2 is not paid in full within thirty (30) days after a written claim therefor by any Person described in Section 10.2(a) has been received by the Partnership, such Person may file proceedings to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Partnership shall have the burden of proving that such Person is not entitled to the requested indemnification or advancement of expenses under applicable Law.

(d) Insurance. To the fullest extent permitted by law, the Partnership may purchase and maintain insurance on behalf of any Person described in Section 10.2(a) against any liability asserted against such Person, whether or not the Partnership would have the power to indemnify such Person against such liability under the provisions of this Section 10.2 or otherwise.

(e) Non-Exclusivity of Rights. The provisions of this Section 10.2 shall be applicable to all actions, claims, suits or proceedings made or commenced after the date of this Agreement, whether arising from acts or omissions to act occurring before or after its adoption. The provisions of this Section 10.2 shall be deemed to be a contract between the Partnership and each Person entitled to indemnification under this Section 10.2 (or legal representative thereof) who serves in such capacity at any time while this Section 10.2 and the relevant provisions of applicable Law, if any, are in effect, and any amendment, modification or repeal hereof shall not affect any rights or obligations then existing with respect to any state of facts or any action, suit or proceeding then or theretofore existing, or any action, suit or proceeding thereafter brought or threatened based in whole or in part on any such state of facts. If any provision of this Section 10.2 shall be found to be invalid or limited in application by reason of any law or regulation, it shall not affect the validity of the remaining provisions hereof. The rights of indemnification provided in this Section 10.2 shall neither be exclusive of, nor be deemed in limitation of, any rights to which any Person may otherwise be or become entitled or permitted by contract, this Partnership Agreement or as a matter of law, both as to actions in such Person’s official capacity and actions in any

other capacity, it being the policy of the Partnership that indemnification of any Person whom the Partnership is obligated to indemnify pursuant to Section 10.2(a) shall be made to the fullest extent permitted by law.

(f) Certain Terms. For purposes of this Section 10.2, references to “other enterprises” shall include employee benefit plans; 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 Partnership” shall include any service as a director, officer, employee or agent of the Partnership which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries.

(g) Other Protected Persons. This Section 10.2 shall not limit the right of the Partnership, to the extent and in the manner permitted by law, to indemnify and to advance expenses to, and purchase and maintain insurance on behalf of, Persons other than Persons described in Section 10.2(a).

Section 11.10 Submission to Jurisdiction; Waiver of Jury Trial.

(a) Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be finally settled by arbitration conducted by a single arbitrator in New York in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to the dispute fail to agree on the selection of an arbitrator within thirty (30) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of Section 11.10(a), the General Partner may bring, or may cause the Partnership to bring, on behalf of the General Partner or the Partnership or on behalf of one or more Partners, an action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this Section 11.10(b), each Partner (i) expressly consents to the application of Section 11.10(c) to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the General Partner as such Partner’s agent for service of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly advise such Partner of any such service of process, shall be deemed in every respect effective service of process upon the Partner in any such action or proceeding.

In that case, this Section 11.10 shall be construed so as to limit any term or provision so as to make it valid or enforceable within the requirements of the Delaware Arbitration Act or other applicable Law, and, in the event such term or provision cannot be so limited, this Section 11.10 shall be construed to omit such invalid or unenforceable provision.

(c) The General Partner may, in its sole discretion, unilaterally amend this Agreement on or before the effective date of the final regulations to provide for (i) the election of a safe harbor under Proposed Treasury Regulation Section 1.83-3(l) (or any similar provision) under which the fair market value of a partnership interest that is transferred is treated as being equal to the liquidation value of that interest, (ii) an agreement by the Partnership and each of its Partners to comply with all of the requirements set forth in such regulations and Notice 2005-43 (and any other guidance provided by the Internal Revenue Service with respect to such election) with respect to all partnership interests transferred in connection with the performance of services while the election remains effective, (iii) the allocation of items of income, gains, deductions and losses required by the final regulations similar to Proposed Treasury Regulation Section 1.704-1(b)(4)(xii)(b) and (c), and (iv) any other related amendments.

Section 11.14 Headings. The headings and subheadings in this Agreement are included for convenience and identification only and are in no way

intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereof.

Section 11.15 Construction.

Each Limited Partner, by its execution hereof, hereby irrevocably makes, constitutes and appoints the General Partner as its true and lawful agent and attorney in fact, with full power of substitution and full power and authority in its name, place and stead, to make, execute, sign, acknowledge, swear to, record and file (a) this Agreement and any amendment to this Agreement that has been adopted as herein provided; (b) the Certificate and all amendments thereto required or permitted by law or the provisions of this Agreement; (c) all certificates and other instruments (including consents and ratifications which the Limited Partners have agreed to provide upon a matter receiving the agreed support of Limited Partners) deemed advisable by the General Partner to carry out the provisions of this Agreement (including the provisions of Section 8.4) and Law or to permit the Partnership to become or to continue as a limited partnership or partnership wherein the Limited Partners have limited liability in each jurisdiction where the Partnership may be doing business; (d) all instruments that the General Partner deems appropriate to reflect a change or modification of this Agreement or the Partnership in accordance with this Agreement, including, without limitation, the admission of additional Limited Partners or substituted Limited Partners pursuant to the provisions of this Agreement; (e) all conveyances and other instruments or papers deemed advisable by the General Partner to effect the liquidation and termination of the Partnership; and (f) all fictitious or assumed name certificates required or permitted (in light of the Partnership’s activities) to be filed on behalf of the Partnership.
