(a) The full management, control and operation of the Partnership and the formulation and execution of business and investment policy shall be vested in the General Partner, and the General Partner shall have full control over the business and affairs of the Partnership. The General Partner shall, in the General Partner’s discretion, exercise all powers necessary and convenient for the purposes of the Partnership, including, without limitation, those enumerated in Section 2.4, on behalf and in the name of the Partnership. If there shall be more than one General Partner, any action by the General Partners shall require the unanimous approval of the General Partners. All decisions and determinations (howsoever described herein) to be made by the General Partner pursuant to this Agreement shall be made in the General Partner’s discretion, subject only to the express terms and conditions of this Agreement.

(b) All outside business or investment activities of the Partners (including outside directorships or trusteeships) shall be subject to such rules and regulations as are established by the General Partner from time to time.

Section 3.5. Responsibilities of Partners . The General Partner may from time to time establish such rules and regulations applicable to Partners the General Partner deem appropriate.

Section 3.6. [Intentionally omitted] .

Section 3.7. Exculpation and Indemnification . (a)  Liability to Partners . Notwithstanding any other provision of this Agreement, whether express or implied, to the fullest extent permitted by law, no Partner nor any of such Partner’s representatives, agents or advisors nor any partner, member, officer, employee, representative, agent or advisor of the Partnership or any of its Affiliates (individually, a “Covered Person” and collectively, the “Covered Persons”) shall be liable to the Partnership or any other Partner for any act or omission (in relation to the Partnership, this Agreement, any related document or any transaction or investment contemplated hereby or thereby) taken or omitted by a Covered Person (other than any act or omission constituting Cause), unless there is a final and non-appealable judicial determination and/or determination of an arbitrator that such Covered Person did not act in good faith and in what such Covered Person reasonably believed to be in, or not opposed to, the best interests of the Partnership and within the authority granted to such Covered Person by this Agreement, and, with respect to any criminal act or proceeding, had reasonable cause to believe that such Covered Person’s conduct was unlawful. Each Covered Person shall be entitled to rely in good faith on the advice of legal counsel to the Partnership, accountants and other experts or professional advisors, and no action taken by any Covered Person in reliance on such advice shall in any event subject such person to any liability to any Partner or the Partnership. To the extent that, at law or in equity, a Partner has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to another Partner, to the fullest extent permitted by law, such Partner acting under this Agreement shall not be liable to the Partnership or to any such other Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they expand or restrict the duties and liabilities of a Partner otherwise existing at law or in equity, are agreed by the Partners, to the fullest extent permitted by law, to modify to that extent such other duties and liabilities of such Partner.

(b) Indemnification . To the fullest extent permitted by law, the Partnership shall indemnify and hold harmless (but only to the extent of the Partnership’s assets (including, without limitation, the remaining Commitments of the Partners) each Covered Person from and against any and all

-13-

claims, damages, losses, costs, expenses and liabilities (including, without limitation, amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and legal or other costs and reasonable expenses of investigating or defending against any claim or alleged claim), joint and several, of any nature whatsoever, known or unknown, liquidated or unliquidated ( collectively, “Losses” ), arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, in which the Covered Person may be involved, or threatened to be involved, as a party or otherwise, by reason of such Covered Person’s participation in the affairs of the Partnership or which relate to or arise out of or in connection with the Partnership, its property, its business or affairs (other than claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, arising out of any act or omission of such Covered Person constituting Cause); provided , that a Covered Person shall not be entitled to indemnification under this Section with respect to any claim, issue or matter if there is a final and non-appealable judicial determination and/or determination of an arbitrator that such Covered Person did not act in good faith and in what such Covered Person reasonably believed to be in, or not opposed to, the best interest of the Partnership and within the authority granted to such Covered Person by this Agreement, and, with respect to any criminal act or proceeding, had reasonable cause to believe that such Covered Person’s conduct was unlawful; provided further , that if such Covered Person is a Partner or a Withdrawn Partner, such Covered Person shall bear its share of such Losses in accordance with such Covered Person’s Profit Sharing Percentage in the Partnership as of the time of the actions or omissions that gave rise to such Losses. To the fullest extent permitted by law, expenses (including legal fees) incurred by a Covered Person (including, without limitation, the General Partner) in defending any claim, demand, action, suit or proceeding may, with the approval of the General Partner, from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Partnership of a written undertaking by or on behalf of the Covered Person to repay such amount to the extent that it shall be subsequently determined that the Covered Person is not entitled to be indemnified as authorized in this Section, and the Partnership and its Affiliates shall have a continuing right of offset against such Covered Person’s interests/investments in the Partnership and such Affiliates and shall have the right to withhold amounts otherwise distributable to such Covered Person to satisfy such repayment obligation. If a Partner institutes litigation against a Covered Person which gives rise to an indemnity obligation hereunder, such Partner shall be responsible, up to the amount of such Partner’s Interests and remaining Commitment, for such Partner’s pro rata share of the Partnership’s expenses related to such indemnity obligation, as determined by the General Partner. The Partnership may purchase insurance, to the extent available at reasonable cost, to cover losses, claims, damages or liabilities covered by the foregoing indemnification provisions. Partners will not be personally obligated with respect to indemnification pursuant to this Section.

Section 3.8. Tax Representation . Each Limited Partner certifies that (A) (x) (i) the Limited Partner’s name, social security number and address provided to the Partnership and its Affiliates pursuant to an IRS Form W-9, Payer’s Request for Taxpayer Identification Number Certification (“ W-9 ”) or otherwise are correct and (ii) the Limited Partner will complete and return a W-9, and (y) (i) the Limited Partner is not a non-resident alien individual (as defined in the Code) and (ii) the Limited Partner will notify the Partnership within 60 days of a change to foreign (non-United States) status or (B) (x) (i) the information on the completed IRS Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding, (“W-8BEN”) or otherwise is correct and (ii) the Limited Partner will complete and return a W-8BEN and (y) (i) the Limited Partner is a non-resident alien individual (as defined in the Code) and (ii) the Limited Partner will notify the Partnership within 60 days of change of foreign (non-United States) status.

ARTICLE IV

CAPITAL OF THE PARTNERSHIP

Section 4.1. Capital Contributions by Partners . (a) Except as agreed by the Managing Member and a Regular Member, such Limited Partner shall not be required to make capital contributions to the Partnership at such times and in such amounts as are required to fund the Required Amounts, as determined by the General Partner from time to time; provided, that (i) such additional capital contributions may be made pro rata among the Limited Partners based upon the allocation of the Carried Interest in each BREI Investment by the General Partner and (ii) additional capital contributions in excess of Required Amounts which are to be used for ongoing business operations (as distinct from financing legal or other specific liabilities of the Partnership) (including those specifically set forth in Sections 4.1(d) and 5.8(d)); provided further, that the General Partner may excuse any Nonvoting Limited Partner from making capital contributions to fund Required Amounts as provided in the books and records of the Partnership. Limited Partners (other than Special Limited Partners) shall not be required to make additional capital contributions to the Partnership except (i) as a condition of an increase in such Limited Partner’s Profit Sharing Percentage, or (ii) as specifically set forth in this Agreement; provided, however, that the General Partner and any Limited Partner (other than a Special Limited Partner) may agree from time to time that such Limited Partner shall make an additional capital contribution to the Partnership; provided further that each Investor Limited Partner shall maintain its capital account at a level equal to the product of (i) its Profit Sharing Percentage from time to time and (ii) the total capital of the Partnership; provided further, that the foregoing in no way limits any other provision of this Agreement (including without limitation, Sections 5.8(d) and (e) and 6.5) or of any written agreement between a Partner and the Partnership or an Affiliate thereof which requires the making of any such additional capital contribution. If required by applicable law, the maximum amount of capital a Limited Partner is obligated to contribute to the Partnership shall be disclosed in a Certificate filed in accordance with the Partnership Act; and provided further, that the General Partner shall be required to make a maximum capital contribution of (U.S.)$1,000. Notwithstanding the foregoing, the unfunded amount of any Limited Partner’s commitment to make capital contributions to the Partnership (such Limited Partner’s “Unfunded Commitment”) may be determined and redetermined by the General Partner from time to time (including, without limitation, any redetermination that results in a reduction in such Limited Partner’s Unfunded Commitment, which reduction may be retroactive); provided that each Limited Partner agrees to make capital contributions in the full amount of such Limited Partner’s Unfunded Commitment at any time, on condition that the General Partner does not thereafter make a redetermination that results in a reduction in such Limited Partner’s Unfunded Commitment and subject to all other terms and conditions set forth herein and/or in any other agreement relating thereto; and provided further, that, following an initial determination of a Limited Partner’s commitment such Limited Partner’s Unfunded Commitment shall not be increased without the consent of such Limited Partner. Any provision of this Agreement to the contrary notwithstanding, no capital contribution shall become due and payable or be required to be made by any Partner, unless and until it shall be called by the General Partner for the purposes set forth herein or in the Commitment Agreements or SMD Agreements of such Partner.

(b) Each capital contribution by a Partner shall be credited to the appropriate capital account of such Partner in accordance with Section 5.2.

(c) The General Partner may elect on a case by case basis to (i) cause the Partnership to loan any Partner (including any additional Partner admitted to the Partnership pursuant to Section 6.1 but excluding any Partner that is an executive officer of The Blackstone Group L.P.) the amount of any capital contribution required to be made by such Partner or (ii) permit any Partner (including any additional Partner admitted to the Partnership pursuant to Section 6.1) to make a required capital contribution to the Partnership in installments in kind, in each case on terms (including valuation of contributed property in the case of in kind contributions permitted by the General Partner) determined by the General Partner.

(d) (i) The Partners have entered into the Trust Agreement, pursuant to which certain amounts of the distributions relating to the Carried Interest will be paid to the Trustee(s) for deposit in the Trust Account (such amounts to be paid to the Trustee(s) for deposit in the Trust Account constituting a “ Holdback ”). The General Partner shall determine, as set forth below, the percentage of each distribution of Carried Interest that shall be withheld for each Partner Category (such withheld percentage constituting such Partner Category’s “ Holdback Percentage ”). The applicable Holdback Percentages initially shall be 15% for Existing Partners (other than the General Partner), 0% for Holdings, 21% for Retaining Withdrawn Partners and 24% for Deceased Partners (the “ Initial Holdback Percentages ”).

(ii) The Holdback Percentage may not be reduced for any individual Partner as compared to the other Partners in his Partner Category (except as provided in clause (iv) below). The General Partner may only reduce the Holdback Percentages among the Partner Categories on a proportionate basis; provided, that the Holdback Percentage applicable to Holdings may not be increased or decreased without its consent. For example, if the Holdback Percentage for Existing Partners is decreased to 12.5%, the Holdback Percentage for Retaining Withdrawn Partners and Deceased Partners shall be reduced to 17.5% and 20%, respectively. Any reduction in the Holdback Percentage for any Partner shall apply only to distributions relating to Carried Interest made after the date of such reduction.

(iii) The Holdback Percentage may not be increased for any individual Partner as compared to the other Partners in his Partner Category (except as provided in clause (iv) below). The General Partner may not increase the Retaining Withdrawn Partners’ Holdback Percentage beyond 21% unless the General Partner increases the Existing Partners’ Holdback Percentage to 21%. The General Partner may not increase the Deceased Partners’ Holdback Percentage beyond 24% unless it increases the Holdback Percentage for both Existing Partners and Retaining Withdrawn Partners to 24%. The General Partner may not increase the Holdback Percentage of any Partner Category beyond 24% unless such increase applies equally to all Partner Categories. Any increase in the Holdback Percentage for any Partner shall apply only to distributions relating to Carried Interest made after the date of such increase. The foregoing shall in no way prevent the General Partner from proportionately increasing the Holdback Percentage of any Partner Category (following a reduction of the Holdback Percentages below the Initial Holdback Percentages), if the resulting Holdback Percentages are consistent with the above. For example, if the General Partner reduces the Holdback Percentages for Existing Partners, Retaining Withdrawn Partners and Deceased Partners to 12.5%, 17.5% and 20%, respectively, the General Partner shall have the right to subsequently increase the Holdback Percentages to the Initial Holdback Percentages.

(iv) (A) Notwithstanding anything contained herein to the contrary, the Partnership may increase or decrease the Holdback Percentage for any Partner in any Partner Category (in such capacity, the “ Subject Partner ”) pursuant to a majority vote of the Special Limited Partners and of the special limited partners of BRE Associates (a “ Holdback Vote ”); provided , that, notwithstanding anything to the contrary contained herein, the Holdback Percentage applicable to the General Partner shall not be increased or decreased without its prior written consent; provided further , that a Subject Partner’s Holdback Percentage shall not be (I) increased prior to such time as such Subject Partner (x) is notified by the Partnership of the decision to increase such Subject Partner’s Holdback Percentage and (y) has, if requested by such Subject Partner, been given 30 days to gather and provide information to the Partnership for

-16-

consideration before a second Holdback Vote (requested by the Subject Partner) and (II) decreased unless such decrease occurs subsequent to an increase in a Subject Partner’s Holdback Percentage pursuant to a Holdback Vote under this clause (iv); provided further , that such decrease shall not exceed an amount such that such Subject Partner’s Holdback Percentage is less than the prevailing Holdback Percentage for such Subject Partner’s Partner Category; provided further , that a Partner or a special limited partner of BRE Associates shall not vote to increase a Subject Partner’s Holdback Percentage unless such voting partner determines, in his good faith judgment, that the facts and circumstances indicate that it is reasonably likely that such Subject Partner, or any of his successors or assigns (including his estate or heirs) who at the time of such vote holds the Partnership interest or otherwise has the right to receive distributions relating thereto, will not be capable of satisfying any Recontribution Amounts that may become due.

(B) A Holdback Vote shall take place at a Partnership meeting, which shall also include the special limited partners of BRE Associates. Each Special Limited Partner or special limited partner of BRE Associates shall be entitled to cast one vote with respect to the Holdback Vote regardless of such Special Limited Partner’s interest in the Partnership or special limited partner of BRE Associates’s interest in BRE Associates, as the case may be. Such vote may be cast by any such Special Limited Partner or special limited partner in person or by proxy.

(C) If the result of the second Holdback Vote is an increase in a Subject Partner’s Holdback Percentage, such Subject Partner may submit the decision to an arbitrator, the identity of which is mutually agreed upon by both the Subject Partner and the Partnership; provided , that if the Partnership and the Subject Partner cannot agree upon a mutually satisfactory arbitrator within 10 days of the second Holdback Vote, each of the Partnership and the Subject Partner shall request its candidate for arbitrator to select a third arbitrator satisfactory to such candidates; provided further , that if such candidates fail to agree upon a mutually satisfactory arbitrator within 30 days of such request, the then sitting President of the American Arbitration Association shall unilaterally select the arbitrator. Each Subject Partner that submits the decision of the Partnership pursuant to the second Holdback Vote to arbitration and the Partnership shall estimate their reasonably projected out-of-pocket expenses relating thereto and each such party shall, to the satisfaction of the arbitrator and prior to any determination being made by the arbitrator, pay the total of such estimated expenses (i.e., both the Subject Partner’s and the Partnership’s expenses) into an escrow account to be controlled by Simpson Thacher & Bartlett LLP, as escrow agent (or such other comparable law firm as the Partnership and Subject Partner shall agree). The arbitrator shall direct the escrow agent to pay out of such escrow account all expenses associated with such arbitration (including costs leading thereto) and to return to the “victorious” party the entire amount of funds such party paid into such escrow account. If the amount contributed to the escrow account by the losing party is insufficient to cover the expenses of such arbitration, such “losing” party shall then provide any additional funds necessary to cover such costs to such “victorious” party. For purposes hereof, the “victorious” party shall be the Partnership, if the Holdback Percentage ultimately determined by the arbitrator is closer to the percentage determined in the second Holdback Vote than it is to the prevailing Holdback Percentage for the Subject Partner’s Partner Category; otherwise, the Subject Partner shall be the “victorious” party. The party that is not the “victorious” party shall be the “losing” party.

(D) In the event of a decrease in a Subject Partner’s Holdback Percentage (1) pursuant to a Holdback Vote under this clause (iv) or (2) pursuant to a decision of an arbitrator under paragraph (C) of this clause (iv), the Partnership shall release and distribute to such Subject Partner any Trust Amounts (and the Trust Income thereon (except as expressly

-17-

provided herein with respect to using Trust Income as Firm Collateral)) which exceed the required Holdback of such Subject Partner (in accordance with such Subject Partner’s reduced Holdback Percentage) as though such reduced Holdback Percentage had applied since the increase of the Subject Partner’s Holdback Percentage pursuant to a previous Holdback Vote under this clause (iv).

(v) (A) If a Partner’s Holdback Percentage exceeds 15% (such percentage in excess of 15% constituting the “ Excess Holdback Percentage ”), such Partner may satisfy the portion of his Holdback obligation in respect of his Excess Holdback Percentage (such portion constituting such Partner’s “ Excess Holdback ”), and such Partner (or a Withdrawn Partner with respect to amounts contributed to the Trust Account while he was a Partner), to the extent his Excess Holdback obligation has previously been satisfied in cash, may obtain the release of the Trust Amounts (but not the Trust Income thereon which shall remain in the Trust Account and allocated to such Partner or Withdrawn Partner) satisfying such Partner’s or Withdrawn Partner’s Excess Holdback obligation, by pledging or otherwise making available to the Partnership, on a first priority basis (except as provided below), all or any portion of his Firm Collateral in satisfaction of his Excess Holdback obligation. Any Partner seeking to satisfy all or any portion of the Excess Holdback utilizing Firm Collateral shall sign such documents and otherwise take such other action as is necessary or appropriate (in the good faith judgment of the General Partner) to perfect a first priority security interest in, and otherwise assure the ability of the Partnership to realize on (if required), such Firm Collateral; provided , that in the case of entities listed on the books and records of the Partnership, in which Partners/members are permitted to pledge their interests therein to finance all or a portion of their capital con
