ARTICLE IV - CAPITAL ACCOUNTS; ALLOCATIONS AND DISTRIBUTIONS.

Section 4.1                                    Capital Accounts.

(a)                     There shall be established for each Partner a Capital Account.  No Partner shall have the right to withdraw any part of his, her or its (including his, her or its predecessor’s in interest) Capital Account until the dissolution and winding up of the Partnership, except as distributions pursuant to this Article IV may represent returns of capital, in whole or in part.  No Partner shall be entitled to receive any interest on any Capital Account balance.  No Partner shall have any personal liability for the repayment of any Capital Contribution of any other Partner. Except as specifically set forth herein or as may be required under applicable law, the Partners shall not be required to make any further contributions to the Partnership.  No Partner shall make any contribution to the Partnership without the prior consent of the General Partner.

(b)                     The Capital Account of each Partner shall be increased by such Partner’s allocable share of income and gain, if any, of the Partnership (as well as the Capital Contributions made by a Partner after the Effective Time), and shall be decreased by such Partner’s allocable share of deductions and losses, if any, of the Partnership, and by the amount of all distributions made to such Partner.  The amount of any distribution of assets other than cash shall be deemed to be the Fair Market Value of such assets (net of any liabilities encumbering such property that the distributee Partner is considered to assume or take subject to).  Capital Accounts may also be adjusted upon the Transfer of Partnership Interests as set forth in Section 5.2(b).

Section 4.2                                    Allocations.

(a)                     Subject to Sections 4.2(c), 4.5 and 5.3, all items of Partnership income and gain in respect of each LTEIP Underlying Holdco Interest shall be allocated among the Partners’ Capital Accounts at the end of every calendar quarter in accordance with (and in

5

proportion to) each such Partner’s respective number of Partnership Points of the Corresponding LTEIP Series of such LTEIP Underlying Holdco Interest held by such Partner on the first day of such quarter.

(b)                     Subject to Sections 4.2(d), 4.2(e), 4.5 and 5.3, all items of Partnership loss and deduction in respect of each LTEIP Underlying Holdco Interest shall be allocated among the Partners’ Capital Accounts at the end of every calendar quarter in accordance with (and in proportion to) each such Partner’s respective number of Partnership Points of the Corresponding LTEIP Series of such LTEIP Underlying Holdco Interest held by such Partner on the first day of such quarter; provided, that no additional losses shall be allocated to a Partner once his, her or its Capital Account has been reduced to zero (0), unless all Partners’ Capital Accounts have then been reduced to zero (0).

(c)                      If the Partnership has any Capital Surplus from the sale, exchange or disposition of an LTEIP Underlying Holdco Interest, then that Capital Surplus shall be allocated among the Partners’ Capital Accounts in accordance with (and in proportion to) the number of Partnership Points of the Corresponding LTEIP Series of such LTEIP Underlying Holdco Interest held by each such Partner as of the effective date of the transaction.

(d)                     If the Partnership has any Capital Loss from the sale, exchange or disposition of an LTEIP Underlying Holdco Interest, then that Capital Loss shall be allocated among the Partners’ Capital Accounts in accordance with (and in proportion to) the number of Partnership Points of the Corresponding LTEIP Series of such LTEIP Underlying Holdco Interest held by each such Partner as of the effective date of the transaction; provided, that no additional losses shall be allocated to a Partner once his, her or its Capital Account has been reduced to zero (0), unless all Partners’ Capital Accounts have then been reduced to zero (0).

(e)                      To the extent that a Transfer of Partnership Interests from any Limited Partner is deemed, under GAAP, to be compensation granted to the transferee (the amount of such compensation under GAAP, a “Compensation Expense”) and a contribution by the transferring Limited Partner, such Limited Partner’s Capital Account shall (i) immediately prior to such Transfer, be increased by the amount of such Compensation Expense and (ii) immediately after such Transfer, be decreased by the amount of such Compensation Expense.

Section 4.3                                    Distributions.

(a)                     Subject to Section 4.4, within thirty (30) days after the end of each calendar quarter, to the extent cash is available therefor at the Partnership, the Partnership shall, based on the unaudited financial statements for such calendar quarter, distribute to each Partner an amount equal to the positive difference resulting from (i) the allocation of income and gain to such Partner pursuant to Section 4.2(a) for such calendar quarter, minus (ii) the allocation of loss and deduction to such Partner pursuant to Section 4.2(b) for such calendar quarter.

(b)                     Except to the extent distributions are provided for in Section 4.3(a), any other amounts available for distribution to the Partners shall be distributed to the Partners at such times as may be determined by the General Partner (but in any event, the General Partner shall cause the Partnership to distribute to the Partners such amount as is necessary to meet taxation obligations arising from the allocations of income and gain pursuant to this Article IV), provided that any such distribution shall be made among the Partners: (i) if attributable to

6

a sale of all, or a substantial portion (as determined by the General Partner) of the assets of the Partnership, then in the same manner and order as such distribution would have been made under Section 4.4 upon a dissolution; (ii) if attributable to a sale of any such asset other than as described in clause (i), a distribution of the resulting Capital Surplus shall be made in accordance with allocations of Capital Surplus pursuant to Section 4.2(c); and (iii) if attributable other than to a sale described in clause (i) or (ii), then in accordance with (and in proportion to) their respective number of Partnership Points as of the last day of the calendar quarter ending immediately prior to such distribution; provided, that no additional distribution shall be made to a Partner once its Capital Account has been reduced to zero (0).

(c)                      Notwithstanding any other provision of this Agreement, neither the Partnership, nor the General Partner on behalf of the Partnership, shall make a distribution to any Partner on account of its Partnership Interests if such distribution would violate the Act or other applicable law.

Section 4.4                                    Distributions Upon Dissolution; Establishment of a Reserve Upon Dissolution.

(a)                     Upon the dissolution of the Partnership, after payment (or the making of reasonable provision for the payment) of all liabilities of the Partnership owing to creditors, the General Partner, or if there is none, the Liquidating Trustee appointed as set forth in Section 7.4, shall set up such reserves as it deems reasonably necessary for any contingent, conditional or unmatured liabilities or other obligations of the Partnership.  Such reserves may be paid over by the General Partner or Liquidating Trustee to a bank (or other third party), to be held in escrow for the purpose of paying any such contingent, conditional or unmatured liabilities or other obligations.  At the expiration of such period(s) as the General Partner or Liquidating Trustee may deem advisable, such reserves, if any (and any other assets available for distribution), or a portion thereof, shall be distributed to the Partners (following the allocation to the Partners’ Capital Accounts of any income, gain, loss, deduction, Capital Surplus or Capital Loss in the manner provided in Section 4.2) among the Partners in accordance with (and in proportion to) their respective Capital Accounts as of the date of dissolution.

(b)                     If any assets of the Partnership are to be distributed in kind in connection with such liquidation, such assets shall be distributed on the basis of their Fair Market Value net of any liabilities encumbering such assets and, to the greatest extent possible, shall be distributed pro rata in accordance with the total amounts to be distributed to each Partner.  Immediately prior to the effectiveness of any such distribution in kind, each item of gain and loss that would have been recognized by the Partnership had the property being distributed been sold at Fair Market Value shall be determined and allocated to those persons who were Partners immediately prior to the effectiveness of such distribution in accordance with Sections 4.2(c) and 4.2(d).

Section 4.5                                    Certain Special Allocations; Proceeds from Capital Contributions.

(a)                     Notwithstanding any other provision in this Article IV, if there is a net decrease in Partnership Minimum Gain or Partner Nonrecourse Debt Minimum Gain (determined in accordance with the principles of U.S. Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during any 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

7

U.S. Treasury Regulations Sections 1.704-2(g)(2) and 1.704-2(i)(5).  The items to be so allocated shall be determined in accordance with U.S. Treasury Regulations Section 1.704-2(f).  This Section 4.5(a) is intended to comply with the minimum gain chargeback requirements in such U.S. Treasury Regulations Sections and shall be interpreted consistently therewith; including that no chargeback shall be required to the extent of the exceptions provided in U.S. Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4).

(b)                     In the event any Partner unexpectedly receives any adjustments, allocations, or distributions described in U.S. 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 his Capital Account created by such adjustments, allocations or distributions as promptly as possible.

(c)                      In the event 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 U.S. 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 4.5(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 IV have been tentatively made as if Section 4.5(b) and this Section 4.5(c) were not in this Agreement.

(d)                     Nonrecourse Deductions shall be allocated among the Partners in accordance with their respective numbers of Partnership Points.

(e)                      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 U.S. Treasury Regulations Section 1.704-2(j).

(f)                       The allocations set forth in Sections 4.5(a), (b), (c), (d) and (e) (the “Regulatory Allocations”) are intended to comply with certain requirements of the U.S. Treasury Regulations.  It is the intent of the Partners that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Partnership income, gain, loss or deduction pursuant to this Section 4.5(f), and to the extent Regulatory Allocations are necessary, it is the intent of the Partners that they be made in as consistent a manner with the provisions of Section 4.2 as practicable, subject to compliance with the U.S. Treasury Regulations.  Therefore, notwithstanding any other provision of this Article IV (other than the Regulatory Allocations), the General Partner shall make such offsetting special allocations of Partnership income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s Capital Account and net allocations are, to the extent possible, equal to the Capital Account balance and net allocation such Partner would have had if the Regulatory Allocations were not a part of this Agreement and all Partnership items were allocated pursuant to Section 4.2.  In exercising its discretion under this Section 4.5(f), the General Partner shall take into account future Regulatory Allocations under Section 4.5(a) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Sections 4.5(d) and (e).

8

(g)                      Capital Contributions made by any Partner may, in the sole discretion of the General Partner, be used for the benefit of the Partnership, or, may be distributed by the Partnership, in which case, any such proceeds shall be allocated and distributed among the Partners in accordance with (and in proportion to) their respective Capital Accounts as of immediately prior to such contribution (it being understood that in the case the proceeds are a note receivable, any such distribution shall only occur upon receipt by the Partnership of cash in respect thereof).

Section 4.6                                    Federal Tax Allocations. The General Partner shall, in its sole discretion, allocate the ordinary income and losses and capital gains and losses of the Partnership as determined for U.S. Federal income tax purposes (and each item of income, gain, loss, deduction or credit entering into the computation thereof), as the case may be, among the Partners for tax purposes in a manner that, to the greatest extent possible:  (a) reflects the economic arrangement of the Partners under this Agreement (determined after taking into account the allocation and distribution provisions this Article IV) and (b) is consistent with the principles of Sections 704(b) and 704(c) of the Code.  The Partners understand and agree that, with respect to any item of property (other than cash) contributed (or deemed to be contributed for U.S. federal income tax purposes) by a Partner to the capital of the Partnership, the initial tax basis of such property in the hands of the Partnership will be the same as the tax basis of such property in the hands of such Partner at the time so contributed.  The Partners further understand and agree that the taxable income and taxable loss of the Partnership is to be computed for Federal income tax purposes by reference to the initial tax basis to the Partnership of any assets and properties contributed by the Partners (and not by reference to the Fair Market Value of such assets and properties at the time contributed).  The Partners also understand that, pursuant to Section 704(c) of the Code, all taxable items of income, gain, loss and deduction with respect to such assets and properties shall be allocated among the Partners for Federal income tax purposes so as to take account of any difference between the initial tax basis of such assets and properties to the Partnership and their Fair Market Values at the time contributed, using any method authorized by the Income Tax Regulations under Section 704(c) and selected by the General Partner, in its sole discretion.  For purposes of maintaining the Capital Accounts of the Partners, items of income, gain, loss and deduction relating to any asset or property contributed to the Partnership that are required to be allocated for tax purposes pursuant to Section 704(c) of the Code shall not be reflected in the Capital Accounts of the Partners.

Section 4.7                                    Profits Interests.  The Partnership Points are intended to constitute “profits interests” within the meaning of Revenue Procedures 93-27, 1993-2 C.B. 343 (June 9, 1993) and 2001-43, 2001-2 C.B. 191 (August 20, 2001) (“Profits Interests”) for federal income tax purposes, and the provisions of this Agreement shall be interpreted in a manner consistent with such intended treatment.  The Partnership and each Partner agree to treat the Partnership Points as Profits Interests in accordance with the foregoing intent.  The General Partner is authorized to cause the Partnership to make an election to value any Partnership Point at liquidation value (a “Safe Harbor Election”), as the same may be permitted pursuant to or in accordance with the finally promulgated successor rules to Proposed Treasury Regulation Section 1.83-3(l) and IRS Notice 2005-43, 2005-1 C.B. 1221 (May 20, 2005) (collectively, the “Proposed Rules”).  Any such Safe Harbor Election shall be binding on the Partnership and on all of its Partners with respect to all transfers of Partnership Points thereafter made by the Partnership while a Safe Harbor Election is in effect.  A Safe Harbor Election once made may be revoked by the Partnership as permitted by the Proposed Rules or any applicable rule.  The Partnership shall file

9

or cause to be filed all returns, reports and other documentation as may reasonably be required to perfect and maintain the Safe Harbor Election.  The General Partner is hereby authorized and empowered, without further vote or action of the Limited Partners to amend the Agreement as necessary to comply with the Proposed Rules or any rule, in order to provide for a Safe Harbor Election and the ability to maintain or revoke the same, and shall have the authority to execute any such amendment by and on behalf of each Limited Partner.  Each Partner agrees to use commercially reasonable efforts to cooperate with any reasonable request of the General Partner to perfect and maintain any Safe Harbor Election, and to timely execute and deliver any documentation with respect thereto reasonably requested by the Partnership.  Notwithstanding the foregoing, no Covered Person shall be liable to the Partnership, its Controlled Affiliates or any other Covered Person for any loss, damage or claim incurred by reason of any failure of any Partnership Point to be treated as a Profits Interest within the meaning of Revenue Procedure 93-27, 1993-2 C.B. 343 (June 9, 1993), or any other act that may or may not be taken as contemplated by this Section 4.7.  In the event that any of the Partnership, the General Partner or any Limited Partner receives written notice from the IRS that the Partnership Points do not constitute Profits Interests for federal income tax purposes, such Person shall promptly provide notice thereof to the General Partner, and the General Partner shall provide notice thereof to each Individual Equityholder as soon as reasonably practicable thereafter.

ARTICLE V - TRANSFERS; ADMISSIONS; RESIGNATION, REDEMPTION AND WITHDRAWAL.

Section 5.1                                    Transferability of Partnership Interests.  No Partnership Interests held by any Partner (or transferee thereof), or direct or indirect ownership interest in any Partner which is not a natural person, may be Transferred and no such Transfer shall be binding upon the Partnership or any Partner, unless, in each case, it is expressly permitted by this Article V and the General Partner receives an executed copy of the documents effecting such Transfer (which shall be in form and substance reasonably satisfactory to the General Partner); provided, that a Change of Control of AMG (and the resulting Change of Control of the General Partner) shall not constitute such a Transfer, regardless of how structured.  No transferee of Partnership Interests shall become a substitute Partner, and no Partner in which any direct or indirect ownership interests have been Transferred shall remain a Partner, in either case, except upon the terms and conditions set forth in Section 5.2.  If a transferee of Partnership Interests of a Partner in the Partnership does not become (and until any such transferee becomes) a substitute Partner, or if a Partner in which an ownership interest has been Transferred does not remain a Partner following such Transfer, in either case, in accordance with the provisions of Section 5.2, such Person shall not be entitled to exercise or receive any of the rights, powers or benefits of a Partner other than the right to receive allocations of profits and losses and distributions which the assigning Partner has Transferred to such Person in compliance with this Article V, or if such Person does not remain a Partner by reason of the Transfer of an ownership interest in such Person, the allocations of profits and losses and distributions payable in respect of the Partnership Interest held by such Person.  Subject to Section 5.6, a Partner’s Partnership Interest, and in the case of a Partner which is not a natural person, a direct ownership interest in such Partner, may be Transferred solely as follows:

(a)                     in the case of a Limited Partner, (i) with the prior written consent of the General Partner, (ii) in accordance with the provisions of Article VI, (iii) upon the death of the Individual Equityholder related to such Limited Partner, by will or the laws of descent and

10

distribution, and (iv) to members of the Immediate Family of the Individual Equityholder related to such Limited Partner (excluding for this purpose, former spouses); and

(b)                     in the case of the General Partner, (i) upon a Supermajority Limited Partner Vote of each LTEIP Series, (ii) to a Permitted AMG Transferee (provided that immediately upon the transferee ceasing to be a Permitted AMG Transferee, the transferee shall automatically be deemed to have transferred back to the General Partner all of the rights and obligations assigned to it hereunder), (iii) AMG’s and/or any of its Controlled Affiliates’ (including the General Partner’s) direct and indirect interests in the Partnership may be pledged and encumbered, and lien holders of AMG’s and/or any of its Controlled Affiliates’ (including the General Partner’s) Partnership Interests may have and be able to exercise the rights of secured creditors with respect to such interests (including, without limitation, foreclosure on such interests by such Persons), and (iv) to an existing Limited Partner or to a Person who is not a Limited Partner but who becomes a Limited Partner;

provided, that in each case, (x) the Transferee enters into an agreement with the Partnership agreeing to be bound by the provisions hereof, and (y) whether or not the Transferee enters into such an agreement, the Transferred Partnership Interests shall thereafter remain subject to this Agreement to the same extent they would be if held by such Partner.

Section 5.2                                    Substitute Partners.

(a)                     The General Partner may admit, in its sole discretion as a substitute Partner (with respect to all or a portion of the Partnership Interests held by a Person), any Person that acquires Partnership Interests by Transfer from another Partner pursuant to Section 5.1 and the General Partner may in its sole discretion permit any Partner in which all of the ownership interests have been Transferred to remain a Partner of the Partnership (and such Partner otherwise automatically shall cease to be a Partner of the Partnership).  The admission of a Transferee as a substitute Partner shall, in all events, be conditioned upon the execution of an instrument satisfactory to the General Partner whereby such Transferee becomes a party to this Agreement as a Partner.

(b)                     Immediately prior to the effectiveness of the admission of a Transferee of Partnership Interests of a Partner as a substitute Partner with respect to such Partnership Interests pursuant to the provisions of this Section 5.2, the General Partner may, in its sole discretion, elect to revalue the assets of the Partnership effective immediately prior to such admission.  If the General Partner elects to revalue the assets of the Partnership then the Capital Accounts of all the Partners shall be adjusted as follows: (i) the General Partner shall determine the proceeds which would be realized if the Partnership sold all its assets immediately prior to the effectiveness of such admission, for a price equal to the Fair Market Value of such assets determined as provided for herein, and (ii) the General Partner shall allocate amounts equal to the net gain or net loss which would have been realized upon such a sale to the Capital Accounts of all the Partners immediately prior to the effectiveness of such admission, in accordance with the provisions of Section 4.2(c) or Section 4.2(d), as applicable.

Section 5.3                                    Allocations and Distributions as between Transferor and Transferee; Successor to Capital Accounts.  Notwithstanding anything to the contrary in Section 4.2, in the event of a Transfer of Partnership Interests pursuant to this Agreement, (a) allocations pursuant to Article IV shall be made on a pro-rata basis to those Persons who held such Transferred

11

Partnership Interests during such calendar quarter based upon the respective number of calendar days during such calendar quarter that such Persons held such Partnership Interests prior to and following such Transfer, and (b) distributions pursuant to Article IV shall be made to those Persons who received the corresponding allocations of Partnership income and gain under Article IV.  In connection with a Transfer by a Partner of Partnership Points of any LTEIP Series, the Transferee shall succeed to a pro rata (based on the percentage of such Partner’s Partnership Points of such LTEIP Series so Transferred) portion of the Transferor’s Capital Account (net of amounts previously allocated but not yet distributed to such Partner hereunder), unless the Transferor and Transferee otherwise agree and so direct the Partnership and the General Partner in a written statement signed by both the Transferor and Transferee and, unless such agreement makes no change other than to reserve to the Transferor all or a portion of distributions pursuant to Article IV, consented to by the General Partner; provided, that in the case of a Transfer by the General Partner of Partnership Points, the Transferee shall not succeed to any portion of the General Partner’s Capital Account unless the General Partner otherwise consents.

Section 5.4                                    Issuance of Additional Partnership Points.

(a)                              Subject to Section 5.6, additional Limited Partners (each, an “Additional Limited Partner”) may be admitted to the Partnership, and such Additional Limited Partners may be issued Partnership Points of a new LTEIP Series, only upon the prior written consent of the General Partner (and upon such terms and conditions as may be established by the General Partner, including, without limitation, upon such Additional Limited Partner’s execution of an instrument in form and substance satisfactory to the General Partner whereby such Person becomes a party to this Agreement as a Limited Partner).

(b)                              Subject to Section 5.6, existing Limited Partners may be issued Partnership Points of a new LTEIP Series only upon the prior written consent of the General Partner (and upon such terms and conditions as may be established by the General Partner).

Section 5.5                                    Resignation, Redemptions, Withdrawals.

(a)                              No Limited Partner shall have the right to resign as a Partner, to cause the redemption of any of its Partnership Interests, in whole or in part, or to withdraw from the Partnership, except (i) with the prior written consent of the General Partner, or (ii) as is expressly provided for in Section 2.9 or Article VI.  Upon any resignation, redemption or withdrawal, the Limited Partner shall only be entitled to the consideration, if any, provided for in Article VI upon the purchase of its Partnership Interests, if and to the extent such Article provides for such a purchase (and shall in no event be entitled to a withdrawal, redemption or distribution of its Capital Account in whole or in part).  If the Partnership Interests acquired from such Limited Partner pursuant to Article VI (together with all Partnership Interests previously acquired from such Limited Partner) constitutes all of the Partnership Interests owned by such Limited Partner prior to such acquisition, such Limited Partner automatically shall be deemed to have withdrawn from the Partnership and shall no longer have any rights under this Agreement, other than the right to receive payments as provided in Article VI if and to the extent such Article so provides.

ARTICLE VI - LTEIP SERIES; VESTING; PUTS AND CALLS.

Section 6.1                                    LTEIP Series.

(a)                              As of the Effective Time, the Partnership had one LTEIP Series outstanding, namely the 2012 Points, which were issued to the Partners in the amounts specified on Schedule A.

13

(b)                              From time to time following the Effective Time, the General Partner may in its sole discretion cause the Partnership to issue Partnership Points of additional LTEIP Series in accordance with the terms of this Agreement.

Section 6.2                                    Vesting of Partnership Points.  Partnership Points of each LTEIP Series held by a Limited Partner shall vest in accordance with the vesting schedule with respect to such LTEIP Series as is set forth opposite the name of such Limited Partner on Schedule A (the vested Partnership Points of a particular LTEIP Series, the “Vested Points”); provided, however, that upon (x) the death or permanent disability of the Individual Equityholder related to such Limited Partner, or (y) a Change of Control of AMG, all of such Limited Partner’s Partnership Points of each LTEIP Series shall immediately become Vested Points of such LTEIP Series.  At any time, Partnership Points of an LTEIP Series held by a Limited Partner which have not yet vested pursuant to the terms of this Section 6.2, shall be referred to as “Unvested Points.”  Notwithstanding the foregoing, the General Partner may in its sole discretion accelerate the vesting of all or any portion of the Unvested Points held by any Limited Partner.  For the avoidance of doubt, any Partnership Points of an LTEIP Series held by the General Partner shall be deemed to be Vested Points while held by the General Partner (including, without, limitation, Partnership Points which are forfeited to the General Partner pursuant to Section 6.3).

Section 6.3                                    Termination Events; Forfeiture of Unvested Points.

(a)                              In the event that the General Partner provides written notice to any Individual Equityholder that the Partnership shall no longer avail itself of the services provided to the Partnership by such Individual Equityholder for any reason (a “Termination Event” with respect to such Individual Equityholder), such Individual Equityholder and each of his or her related Limited Partners shall forfeit to the General Partner (a “Forfeiture”, and such written notice, a “Termination Notice”) all of the Unvested Points held by such Person, with no further obligation on the part of the Partnership or any Partner to such Person with respect thereto.

(b)                              Without any action on the part of any of the Partnership, such Individual Equityholder or any Partner, such Forfeiture shall take place immediately and automatically upon the delivery of such Termination Notice.  Upon any Forfeiture, the General Partner shall be deemed to have acquired all of the Unvested Points of such Individual Equityholder and each of his or her related Limited Partners (including the entire Partnership Interest with respect thereto).  Such Person shall, upon such Forfeiture, cease to have any rights hereunder in respect of such Unvested Points and the related Partnership Interest.

Section 6.4                                    Fair Value Determination.

(a)                              The General Partner shall, on or prior to the last business day of each February immediately preceding an applicable Purchase Date under Section 6.5(a), determine the fair value (“Fair Value”) of the outstanding Partnership Points of each LTEIP Series, as of December 31st of the preceding calendar year, and provide written statements to the Individual Equityholders notifying each such Individual Equityholder of the Fair Value of the Partnership Points of each LTEIP Series then held by such Individual Equityholder and all of his or her related Limited Partners.

(b)                              In addition, for purposes of determining the Purchase Price for Purchased Points in connection with any Put, Departure Call, Cash Flow Call or Competition Call, the

14

General Partner shall determine the Fair Value of such Purchased Points as of the last day of the most recently completed calendar quarter preceding the applicable Purchase Date (the “Applicable Valuation Date”).  For purposes of any determination of Fair Value hereunder by the General Partner or an Appraiser (as applicable), the parties acknowledge and agree that (i) the Fair Value shall be based upon the Partnership’s implied share of the run-rate income (or so called “Owners’ Allocation,” if applicable) of the Applicable AMG Affiliates as derived from the Corresponding LTEIP Underlying Holdco Interests of the applicable LTEIP Series without regard to any expenses, obligations, expenditures or other costs incurred by AMG or its Controlled Affiliates (including, without limitation, the General Partner, the Partnership, AMG WP and the Applicable AMG Affiliates) (provided, that such run-rate income shall take into account any expected “Owners’ Allocation Expenditures” and similar expenses of the Applicable AMG Affiliates) (the “Applicable Cash Flow”), (ii) the Fair Value shall assume a transaction between a willing buyer and willing seller when neither is under compulsion to buy or sell and both have reasonable knowledge of the relevant facts, (iii) the methodologies used to determine the Fair Value of any Partnership Points under this Agreement shall be consistently applied among all Limited Partners, all LTEIP Series and all periods, and (iv) the General Partner may (at the expense of the General Partner) engage an Appraiser to assist it with any determination of Fair Value.  Subject to Section 6.4(c), any such determination of the Fair Value of the Partnership Points shall be final and binding on each of the General Partner and the applicable Limited Partners.

(c)                               Notwithstanding the foregoing, (i) any Individual Equityholder who delivers or receives a Purchase Notice under Section 6.5 or 6.6 shall have the right (on behalf of himself or herself and all of his or her related Limited Partners) to require that the Fair Value of the Purchased Points of any LTEIP Series be determined by an Appraiser (at the expense of the General Partner) if the quotient obtained by (A) the Purchase Price in respect of such Purchased Points, as calculated by the General Partner, divided by (B) the product of (I) the Applicable Cash Flow in respect of the LTEIP Series corresponding to such Purchased Points, and (II) a fraction, (x) the numerator of which is the number of Purchased Points of such LTEIP Series being purchased from the Individual Equityholder and his or her related Limited Partners on such date and (y) the denominator of which is the total number of outstanding Partnership Points of the LTEIP Series corresponding to such Purchased Points as of the applicable Purchase Date (including those to be purchased on such date) is less than six (6.0), and (ii) the General Partner shall have the right to require that the Fair Value of the Purchased Points be determined by an Appraiser (at the expense of the General Partner) if the quotient obtained by (A) the Purchase Price in respect of such Purchased Points, as calculated by the General Partner, divided by (B) the product of (I) the Applicable Cash Flow in respect of the LTEIP Series corresponding to such Purchased Points, and (II) a fraction, (x) the numerator of which is the number of Purchased Points of such LTEIP Series being purchased from the Individual Equityholder and his or her related Limited Partners on such date and (y) the denominator of which is the total number of outstanding Partnership Points of the LTEIP Series corresponding to such Purchased Points as of the applicable Purchase Date (including those to be purchased on such date) is greater than eleven (11.0).  The Individual Equityholder or the General Partner (as applicable) may exercise his, her or its right to such appraisal by providing written notice to the other Person no later than the third (3rd) business day after the Individual Equityholder is informed of the applicable Purchase Price in respect of such Purchased Points.  The Appraiser shall be selected by the Individual Equityholder (if the Individual Equityholder is requiring the appraisal) or the General Partner (if the General Partner is requiring the appraisal); provided, that if more than one Individual Equityholder (on

15

behalf of himself or herself and all of his or her related Limited Partners) is selling Partnership Points on the applicable Purchase Date and requiring an appraisal, the Appraiser shall be the Person selected by plurality vote of such Individual Equityholders (with each Individual Equityholder being deemed to have voted a number of votes equal to such Individual Equityholder’s and his or her related Limited Partners’ total Purchased Points of each LTEIP Series, and the General Partner shall select among the nominated Appraisers to the extent any one Appraiser fails to receive a plurality of the votes). The Appraiser shall be instructed to complete its appraisal as soon as reasonably practicable, and the Purchase Date shall occur as soon as reasonably practicable after the Appraiser has completed its appraisal; provided, that the foregoing shall not result in the delay of the closing of any Cash Flow Call.  Notwithstanding anything to the contrary contained herein, the Appraiser’s determination of the Fair Value of the Purchased Points shall be final and binding on each of the General Partner and the applicable Limited Partner(s) and shall be used to calculate the Purchase Price.

Section 6.5                                    Puts and Calls of Vested Points.

(a)                              An Individual Equityholder may, at such Individual Equityholder’s option, subject to the terms and conditions set forth in this Section 6.5, cause the General Partner to purchase (and in such event the General Partner shall purchase) (a “Put”) from such Individual Equityholder and his or her related Limited Partners (collectively, the “Selling Partner”) up to a number of such Selling Partner’s Vested Points of any LTEIP Series equal to twenty-five percent (25%) of the number of Partnership Points of such LTEIP Series that were issued to such Individual Equityholder on the applicable Issuance Date (or such other percentage and/or date specified by the General Partner with respect to a particular Individual Equityholder to the extent that such Individual Equityholder acquires Partnership Points after such Issuance Date)  (in addition to any Vested Points which previously could have been sold by such Selling Partner pursuant to this Section 6.5 but were not previously sold) annually, on the last business day of the first calendar quarter of each calendar year (a “Purchase Date”), starting with the Applicable Put Start Date in respect of such LTEIP Series.

(b)                              In addition, an Individual Equityholder may exercise his or her Put right hereunder with respect to all or any portion of such Selling Partner’s Vested Points of any LTEIP Series in connection with (x) a Change of Control of AMG, or (y) the death or permanent disability of such Individual Equityholder, and, in each case, the Purchase Date for such Put shall be the later of: (i) the last business day of the second (2nd) full month following the delivery by such Individual Equityholder of a Purchase Notice, or (ii) the last business day of the first (1st) month following the delivery by such Individual Equityholder of a Purchase Notice which would allow the Applicable Valuation Date to be more than six (6) months after the date on which such Partnership Points became Vested Points; provided, however, that if such Purchase Date would otherwise fall on or prior to the last business day of the month following the month in which occurred the second (2nd) anniversary of the applicable Issuance Date, then the applicable Individual Equityholder may elect to delay the Purchase Date until such last business day.  In addition to the foregoing, an Individual Equityholder may exercise his or her Put right hereunder with respect to all or any portion of such Selling Partner’s Vested Points of any LTEIP Series at any time upon the receipt by any of the Partnership, the General Partner or any Individual Equityholder or Limited Partner of written notice from the IRS that the Partnership Points do not constitute Profits Interests for federal income tax purposes, and in such event the Purchase Date for such Put shall be the later of: (x) the last business day of the second (2nd) full month following the delivery by such Individual Equityholder of a Purchase

16

Notice, or (y) the last business day of the first (1st) month following the delivery by such Individual Equityholder of a Purchase Notice which would allow the Applicable Valuation Date to be more than six (6) months after the date on which such Partnership Points became Vested Points.

(c)                               In the event that an Individual Equityholder engages in Competitive Activity at any time, the General Partner may, at its option, subject to the terms and conditions set forth in this Section 6.5, cause the applicable Selling Partner to sell (and in such event such Selling Partner shall sell) all or any portion of the Vested Points of any LTEIP Series held by such Selling Partner (a “Competition Call”) and, in such case, the Purchase Date for such Competition Call shall be the later of: (x) the last business day of the second (2nd) full month following the delivery by the General Partner of a Purchase Notice, or (y) the last business day of the first (1st) month following the delivery by the General Partner of a Purchase Notice which would allow the Applicable Valuation Date to be more than six (6) months after the date on which such Partnership Points became Vested Points; provided, however, that if such Purchase Date would otherwise fall on or prior to the last business day of the month following the month in which occurred the second (2nd) anniversary of the applicable Issuance Date, then the applicable Individual Equityholder may elect to delay the Purchase Date until such last business day.

(d)                              The General Partner may, at its option, subject to the terms and conditions set forth in this Section 6.5, cause any Selling Partner to sell (and in such event such Selling Partner shall sell) (a “Cash Flow Call”) all or any portion of such Selling Partner’s Vested Points of any LTEIP Series on any date designated by the General Partner (effective as of 12:01 a.m. on such date) (a “Purchase Date”) starting with the Applicable Call Start Date in respect of such LTEIP Series; provided, that (i) the General Partner may not exercise a Cash Flow Call with respect to a particular Selling Partner if the applicable Purchase Date is on or after the Applicable Twenty Year Service Date of the applicable Individual Equityholder and a Termination Event with respect to such Individual Equityholder did not occur prior to such Applicable Twenty Year Service Date; and (ii) the General Partner may not exercise a Cash Flow Call in respect of a Purchase Date that would fall during the calendar quarter immediately following any particular Applicable Valuation Date if the Fair Value of the Vested Points calculated as of such Applicable Valuation Date is less than or equal to eighty-five percent (85%) of the Fair Value of such Vested Points calculated as of the date that is twelve (12) months prior to such Applicable Valuation Date.  In the case of any conflict between this Section 6.5(d) and any other sub-section of this Section 6.5, this Section 6.5(d) shall control.

(e)                               Any Individual Equityholder (on behalf of himself or herself and all of his or her related Limited Partners) or the General Partner may exercise a Put, a Cash Flow Call or a Competition Call, as applicable, by delivering to the other Person a written notice in the form attached as Exhibit B (a “Purchase Notice”) stating, with respect to a particular LTEIP Series, the number of Vested Points of such LTEIP Series to be sold and purchased in such Put, Cash Flow Call or Competition Call (as applicable) (the “Purchased Points”), as follows:

Section 6.6                                    Departure Calls of Vested Points.

(a)                              Upon a Termination Event with respect to an Individual Equityholder, the General Partner shall have the right to purchase (a “Departure Call”) from such Individual Equityholder and his or her related Limited Partners (collectively, the “Selling Partner”) (and in such event the Selling Partner shall sell) all or any portion of the Vested Points of any LTEIP Series then held by such Selling Partner, subject to the terms and conditions set forth in this Section 6.6 (all of the Vested Points of a particular LTEIP Series to be purchased in such Departure Call, the “Purchased Points”), and the date for such purchase (the “Purchase Date”) shall be the later of: (x) the last business day of the second (2nd) full month following the delivery of a Purchase Notice by the General Partner to such Individual Equityholder, or (y) the last business day of the first (1st) month following the delivery of such Purchase Notice which would allow the Applicable Valuation Date to be more than six (6) months after the date on which such Partnership Points became Vested Points; provided, however, that if such Purchase Date would otherwise fall on or prior to the last business day of the month following the month in which occurred the second (2nd) anniversary of the applicable Issuance Date, then the applicable Individual Equityholder may elect to delay the Purchase Date until such last business day.  Notwithstanding anything to the contrary in this Section 6.6, the General Partner may in no event exercise a Departure Call with respect to a particular Selling Partner if the Termination Event with respect to the applicable Individual Equityholder occurred after the Applicable Twenty Year Service Date of such Individual Equityholder.

19

counsel, as agent for such Selling Partner, to be held by such bank, accounting firm or counsel for the benefit of and for delivery to such Selling Partner.  Upon such deposit by the General Partner and upon notice thereof given to such Selling Partner, such Selling Partner shall have no further rights under this Agreement with respect to such Partnership Interests (other than the right to withdraw the payment therefor or receive the Promissory Note(s), if any, held by the agent described in the preceding sentence).  Each Selling Partner does hereby irrevocably constitute and appoint the General Partner with full power of substitution, the true and lawful attorney-in-fact and agent of such Selling Partner, to execute and deliver, in such Selling Partner’s (or his, her or its assignee’s) name, place and stead, all instruments (including, without limitation, any Promissory Note), documents and certificates as the General Partner may determine to be necessary, appropriate or convenient to consummate any sale contemplated by Section 6.5 or 6.6 and/or make any deposit contemplated by this Section 6.7(b).  This power of attorney shall be deemed to be coupled with an interest, shall be irrevocable, shall survive and not be affected by the dissolution, bankruptcy, incompetence or legal disability of any Selling Partner and shall extend to such Selling Partner’s successors and assigns.

(c)                               The General Partner may (without the need for any vote or consent of any Partner) assign any or all of its rights and obligations under Section 6.5, Section 6.6 or this Section 6.7, in one or more instances, to any other Person; provided, however, that no such assignment shall relieve the General Partner of its obligation to make payment and/or deliver a Promissory Note (as applicable) in respect of a Purchase Price to the extent not paid or delivered by any such assignee.

(b)                     Unless otherwise expressly provided herein, (i) whenever a conflict of interest exists or arises between the General Partner and any other Partner the resolution or manner of resolution of which is not specifically provided for herein, or (ii) whenever this Agreement or any other agreement contemplated herein or therein provides that the General Partner shall act in a manner that is, or provides terms that are, fair and reasonable to the Partnership or any Partner, the General Partner shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles.  In the absence of bad faith by the General Partner, the resolution, action or term so made, taken or provided by the General Partner shall not constitute a breach of this Agreement or any other agreement contemplated herein or of any duty or obligation of the General Partner at law or in equity or otherwise.

(c)                      Whenever in this Agreement the General Partner is permitted or required to make a decision (i) in its “sole discretion” or under a grant of similar authority or latitude, the General Partner shall be entitled to consider such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Partnership or any other Person, or (ii) in its “good faith”, “reasonable discretion” or under another express standard, the General Partner shall act under such express standard and shall not be subject to any other or different standard imposed by this Agreement or other applicable law.

(d)                     Wherever in this Agreement a factual determination is called for and the

22

applicable provision of this Agreement does not indicate what party or parties are to make the applicable factual determination, and/or the applicable standard to be used in making the factual determination, such determination shall be made by the General Partner in the exercise of its good faith discretion.

Section 9.4                                    Indemnification.  To the fullest extent permitted by applicable law, a Covered Person shall be entitled to indemnification from the Partnership for any loss, damage or claim (including any amounts paid in settlement of any such claims) incurred by such Covered Person 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 reasonably believed to be within the scope of authority conferred on such Covered Person by this Agreement, except that no Covered Person shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such Covered Person by reason of any action or inaction of such Covered Person which constituted fraud, gross negligence, bad faith, willful misconduct or a breach of this Agreement; provided, however, that any indemnity under this Section 9.4 shall be provided out of and to the extent of Partnership assets only, and no Covered Person shall have any personal liability to provide indemnity on account thereof.

Section 9.5                                    Notice; Opportunity to Defend and Expenses.

(a)                     Promptly after receipt by any Covered Person from any third party of notice of any demand, claim or circumstance that, immediately or with the lapse of time, would reasonably be expected to give rise to a claim or the commencement (or threatened commencement) of any action, proceeding or investigation (an “Asserted Liability”) that could reasonably be expected to result in any loss, damage or claim with respect to which the Covered Person might be entitled to indemnification from the Partnership under Section 9.4, the Covered Person shall give notice thereof (the “Claims Notice”) to the Partnership; provided, however, that a failure to give such notice shall not prejudice the Covered Person’s right to indemnification hereunder except to the extent that the Partnership is actually prejudiced thereby.  The Claims Notice shall describe the Asserted Liability in such reasonable detail as is practicable under the circumstances, and shall, to the extent practicable under the circumstances, indicate the amount (estimated, if necessary) of the loss or damage that has been or may be suffered by the Covered Person.

(b)                     The Partnership may elect to compromise or defend, at its own expense and by its own counsel, any Asserted Liability; provided, however, that if the named parties to any action or proceeding include (or could reasonably be expected to include) both the Partnership and a Covered Person, or more than one Covered Persons, and the Partnership is advised that representation of both parties by the same counsel would be inappropriate under applicable standards of professional conduct, the Covered Person may engage separate counsel at the expense of the Partnership.  If the Partnership elects to compromise or defend such Asserted Liability, it shall within twenty (20) business days (or sooner, if the nature of the Asserted Liability so requires) notify the Covered Person of its intent to do so, and the Covered Person shall cooperate, at the expense of the Partnership, in the compromise of, or defense against, such Asserted Liability.  If the Partnership elects not to compromise or defend the Asserted Liability, fails to notify the Covered Person of its election as herein provided, contests its obligation to provide indemnification under this Agreement, or fails to make or ceases making a good faith and diligent defense, the Covered Person may pay, compromise or defend such Asserted Liability all at the expense of the Covered Person.  Except as set forth in the

23

preceding sentence, neither the Partnership nor the Covered Person may settle or compromise any claim over the objection of the other; provided, however, that consent to settlement or compromise shall not be unreasonably withheld.  In any event, the Partnership and the Covered Person may participate at their own expense, in the defense of such Asserted Liability.  If the Covered Person chooses to participate in the defense of any claim, the Covered Person shall make available to the Partnership any books, records or other documents within its control that are necessary or appropriate for such defense, all at the expense of the Partnership.

(c)                      If the Partnership elects not to compromise or defend an Asserted Liability, or fails to notify the Covered Person of its election as above provided, then, to the fullest extent permitted by applicable law, expenses (including legal fees) incurred by a Covered Person in defending any Asserted Liability, shall, from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon satisfaction of any conditions required by applicable law and receipt by the Partnership of an undertaking by or on behalf of the Covered Person to repay such amount if it shall be determined that the Covered Person is not entitled to be indemnified as authorized in Section 9.4.  The Partnership may, if the General Partner deems it appropriate, require any Covered Person for whom expenses are advanced, to deliver adequate security to the Partnership for his obligation to repay such indemnification.

Section 9.6                                    Miscellaneous.

(a)                     The right of indemnification hereby provided shall not be exclusive of, and shall not affect, any other rights to which a Covered Person may be entitled.  Nothing contained in this Article IX shall limit any lawful rights to indemnification existing independently of this Article IX.

(b)                     The indemnification rights provided by this Article IX shall also inure to the benefit of the heirs, executors, administrators, successors and assigns of a Covered Person and any officers, directors, partners, shareholders, employees and Affiliates of such Covered Person (and any former officer, director, member, shareholder or employee of such Covered Person, if the loss, damage or claim was incurred while such person was an officer, director, member, shareholder or employee of such Covered Person).  The General Partner may extend the indemnification called for by Section 9.4 to non-employee agents of the Partnership, the General Partner or its Affiliates.

ARTICLE X -  MISCELLANEOUS.

Section 10.1                             Delivery of AMG Shares. In the event that the General Partner elects to pay all or any portion of a Purchase Price by the delivery of AMG Shares, the number of AMG Shares required to be delivered by the General Partner shall be equal to the quotient obtained by dividing (i) that portion of the Purchase Price to be paid in AMG Shares by (ii) the Average AMG Stock Price.  In the event that there is a stock split (or reverse stock split), stock dividend or other similar event during the relevant measuring periods under the foregoing calculation, equitable and appropriate adjustments shall be made in the application of such calculation of the Average AMG Stock Price to take account of such event.

Section 10.2                             Notices.  All notices, statements, requests, elections, consents or demands permitted or required to be made under this Agreement (“Notices”) shall be in writing, signed by the Person or Persons giving such notice, statement, request, election, consent or demand and

24

shall be delivered personally or by confirmed facsimile, or sent by registered or certified mail, or by commercial courier to the other Partners, at their addresses set forth on the signature pages hereof or on Schedule A, or at such other addresses as may be supplied by written notice given in conformity with the terms of this Section 10.2.  All Notices to the Partnership shall be made to the General Partner c/o John Kingston III, Affiliated Managers Group, Inc., 600 Hale Street, Prides Crossing, Massachusetts 01965.  The date of any such personal or facsimile delivery or the date of delivery by an overnight courier or the date five (5) days after the date of mailing by registered or certified mail, as the case may be, shall be the date of such notice.

Section 10.3                             Successors and Assigns.  Subject to the restrictions on Transfer set forth herein, this Agreement shall be binding upon and shall inure to the benefit of the Partners, the Individual Equityholders and their respective successors, successors-in-title, heirs and assigns, and each and every successor-in-interest to any Partner or Individual Equityholder, whether such successor acquires such interest by way of gift, purchase, foreclosure or by any other method, and each shall hold such interest subject to all of the terms and provisions of this Agreement.

Section 10.4                             Amendments.  Amendments may be made to this Agreement only with (a) a Supermajority Limited Partner Vote of each LTEIP Series and (b) the prior written consent of the General Partner; provided, however, that, without the vote, consent or approval of any Partner, (x) the General Partner shall make such amendments and additions to Schedule A, Schedule B and Schedule C as are required by the provisions hereof, (y) the General Partner may amend this Agreement to correct any printing, stenographic or clerical errors or omissions, and (z) in connection with the issuance of Partnership Points of a new LTEIP Series, the General Partner may amend this Agreement as necessary in order to implement the terms applicable to such new LTEIP Series so long as such amendment would not adversely impact the rights, obligations, terms or preferences of any Limited Partner as in effect as of immediately prior to such amendment.  Except as otherwise specifically provided for herein, (x) an amendment or a modification increasing any liability of a Partner or Individual Equityholder to the Partnership or the other Partners or Individual Equityholders, or adversely affecting the limitation of the liability of a Partner or Individual Equityholder with respect to the Partnership, shall be effective only with that Partner’s or Individual Equityholder’s prior written consent, and (y) an amendment or modification that by its explicit terms would alter or change the rights, obligations, powers or preferences of any Partner or Individual Equityholder in a disproportionate and adverse manner compared to other Partners or Individual Equityholders shall be effective only with the prior written consent of the Partner or Individual Equityholder which would be so affected.

Section 10.5                             No Partition.  No Partner nor any successor-in-interest to any Partner, shall have the right while this Agreement remains in effect to have the property of the Partnership partitioned, or to file a complaint or institute any proceeding at law or in equity to have the property of the Partnership partitioned, and each Partner, on behalf of himself, his successors, representatives, heirs and assigns, hereby waives any such right.  It is the intent of the Partners that during the term of this Agreement, the rights of the Partners and Individual Equityholders and their successors-in-interest, as among themselves, shall be governed by the terms of this Agreement, and that the right of any Partner or successors-in-interest to Transfer or otherwise dispose of his interest in the Partnership shall be subject to the limitations and restrictions of this Agreement.

25

Section 10.6                             No Waiver; Cumulative Remedies.  The failure of any Partner or Individual Equityholder to insist upon strict performance of a covenant hereunder or of any obligation hereunder, irrespective of the length of time for which such failure continues, shall not be a waiver of such Partner’s or Individual Equityholder’s right to demand strict compliance in the future.  No consent or waiver, express or implied, to or of any breach or default in the performance of any obligation hereunder, shall constitute a consent or waiver to or of any other breach or default in the performance of the same or any other obligation hereunder.  For the avoidance of doubt, the General Partner may in its sole discretion waive any requirement or obligation hereunder (including, without limitation, under Section 6.5 or 6.6) with respect to any particular Limited Partner or Individual Equityholder without waiving such requirement or obligation with respect to any other Limited Partner or Individual Equityholder.  The rights and remedies provided by this Agreement are cumulative and the use of any one right or remedy by any party shall not preclude or waive its right to use any or all other remedies.  Said rights and remedies are given in addition to any other rights the parties may have by law, statute, ordinance or otherwise.

Section 10.7                             Dispute Resolution.  All disputes arising in connection with this Agreement shall be resolved by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association.  The arbitration shall be held in Boston, Massachusetts before a single arbitrator selected by the General Partner, who shall have substantial business experience in the investment advisory industry.

Section 10.8                             Prior Agreements Superseded.  This Agreement and the Exhibits and Schedules hereto supersede the prior understandings and agreements among the parties with respect to the subject matter hereof.

Section 10.9                             Captions.  Titles or captions of Articles or Sections contained in this Agreement are inserted as a matter of convenience and for reference, and in no way define, limit, extend or describe the scope of this Agreement or the intent of any provision hereof.

Section 10.10                      Counterparts.  This Agreement may be executed in a number of counterparts, all of which together shall for all purposes constitute one Agreement, binding on all the Partners and Individual Equityholders notwithstanding that all Partners and Individual Equityholders have not signed the same counterpart.

Section 10.11                      Applicable Law; Jurisdiction.  This Agreement and the rights and obligations of the parties hereunder shall be governed by and interpreted, construed and enforced in accordance with the laws of the State of Delaware, without applying the choice of law or conflicts of law provisions thereof.

Section 10.12                      Interpretation.  All terms herein using the singular shall include the plural; all terms using the plural shall include the singular; in each case, the term shall be as appropriate to the context of each sentence.  Throughout this Agreement, nouns, pronouns and verbs shall be construed as masculine, feminine and neuter, whichever shall be applicable.

Section 10.13                      Exhibits and Schedules.

(a)                     The name, identity of any Individual Equityholder, Partnership Points of

26

each LTEIP Series, vesting schedule with respect to Partnership Points of each LTEIP Series that are not vested, and Applicable Twenty Year Service Date, of each Partner shall be listed on Schedule A.  The General Partner shall update Schedule A, Schedule B and Schedule C from time to time as necessary to reflect accurately the information to be contained therein.  Any amendment or revision to Schedule A, Schedule B or Schedule C shall not be deemed an amendment to this Agreement.  Any reference in this Agreement to Schedule A, Schedule B or Schedule C shall be deemed to be a reference to Schedule A, Schedule B or Schedule C as amended and in effect from time to time.

(b)                     All Exhibits and Schedules attached to this Agreement are incorporated and shall be treated as if set forth herein.  Only the General Partner shall have the right to review Schedule A and each Limited Partner expressly waives its rights under the Act (including, without limitation, under Section 17-305 thereof) to review Schedule A (and acknowledges and agrees that such waiver is reasonable in light of the interests of the Partnership and its Partners).  Each Limited Partner shall have the right to receive a copy of this Agreement and the Exhibits and Schedules attached hereto, provided that (i) Schedule A will be redacted with respect to information regarding the other Partners, and (ii) Schedule B and Schedule C will be redacted as to any LTEIP Series with respect to which such Limited Partner does not hold Partnership Points, and such Limited Partner shall have the right to review only that information regarding such Limited Partner’s own Partnership Points and vesting schedule with respect to Partnership Points that are not vested.  Notwithstanding the foregoing, the General Partner may furnish to any one or more Limited Partners (and to the exclusion of any one or more other Limited Partners) such additional information relating to such Schedules as the General Partner determines from time to time.

Section 10.14                      Severability.  The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions hereof, and this Agreement shall be construed in all respects as if such invalid or unenforceable provision were omitted.

Section 10.15                      Creditors.  None of the provisions of this Agreement shall be for the benefit of or enforceable by any creditor of (a) any Partner, or (b) the Partnership, other than a Partner who is also a creditor of the Partnership.
