(a) The General Partner and/or its Affiliates may, in their sole discretion, establish one or more Feeder Funds to accommodate certain investors and to facilitate their indirect participation in the Partnership with respect to all or a portion of their investment therein. Any such Feeder Fund may elect to be treated as a corporation for U.S. federal income tax purposes. Investors in a Feeder Fund generally will have indirect interests in the Partnership on economic terms no more favorable than those of the other Limited Partners that invest in the Partnership.

(b) The General Partner may make any adjustments to the units of a Feeder Fund reasonably necessary to accomplish the overall objectives of this Section 2.11 on the condition that such adjustments shall not materially adversely affect the Units of any other Limited Partner. Nothing in this Section 2.11 should be construed as making any interestholder in a Feeder Fund a Limited Partner for any purpose.

(c) The General Partner and/or its Affiliates may, in their sole discretion, cause the Partnership to hold certain Investments directly or indirectly through (i) entities that may elect to be classified as corporations for U.S. federal income tax purposes, whether formed in a U.S. or non-U.S. jurisdiction (each a “Corporation”) or (ii) one or more limited liability companies or limited partnerships (each, a “Lower Entity,” and together with any Corporation, and including the Aggregator, “Intermediate Entities”).

ARTICLE III

SUBSCRIPTIONS; DISTRIBUTIONS

SECTION 3.1. Subscriptions.

(a) Partners will make Subscriptions to the Partnership in exchange for Units as more fully described in the Memorandum. Each Partner, by executing a Subscription Agreement, shall be deemed to have acknowledged and consented to the risks and other considerations relating to an investment in the Partnership, including the risks and conflicts described in the Memorandum. Each Partner’s Unit holdings will be set forth opposite their names on the Partnership’s books and records. The General Partner or any transfer agent or similar agent may keep the Partnership’s books and records current through separate revisions that reflect periodic changes to each Limited Partner’s Units (including as a result of Subscriptions or repurchases) without preparing an amendment to this Agreement. The Partners shall have no right or obligation to make any additional Subscriptions or loans to the Partnership.

(b) The General Partner is hereby authorized to cause the Partnership to issue such additional Units for any Partnership purpose at any time or from time to time to the Partners (including the General Partner) or to other Persons for such consideration and on such terms and conditions as shall be established by the General Partner in its sole and absolute discretion, all

13

without the approval of any Limited Partners. Any additional Units issued thereby may be issued in one or more classes (including the classes specified in this Agreement or any other classes), or one or more series of any of such classes, with such designations, preferences and relative, participating, optional or other special rights, powers and duties, including rights, powers and duties senior to Units, all as shall be determined by the General Partner in its sole and absolute discretion and without the approval of any Limited Partner, subject to Delaware law.

(c) Each new Partner shall be admitted as a Partner upon the General Partner’s acceptance of an executed Subscription Agreement or other agreement pursuant to which such Partner becomes bound by the terms of this Agreement.

(d) Subscriptions may be accepted or rejected in whole or in part by the General Partner on behalf of the Partnership in its sole discretion.

(e) Admission of a new Limited Partner shall not cause dissolution of the Partnership.

(f) Unless otherwise agreed to by the General Partner, Subscriptions to the Partnership must be made in U.S. dollars by wire transfer of immediately available funds on or prior to the date Units are to be issued. The General Partner may accept, on behalf of the Partnership, a Subscription to the Partnership in the form of a non-cash contribution on terms and conditions that the General Partner deems appropriate in good faith. The Agreed Value of any non-cash Subscriptions by a Partner as of the date of contribution are set forth on the Partnership’s books and records. No Units shall be deemed issued by the Partnership to a Partner until they are paid for in the amount and form agreed to with the General Partner. When issued pursuant to and in accordance with this Agreement, Units shall be fully paid and non-assessable, to the fullest extent permitted by law.

SECTION 3.2. Distributions – General Principles.

(a) Except as otherwise expressly provided in this Article III or in Article IX, no Partner shall have the right to withdraw capital from the Partnership or to receive any distribution or return of its Subscription. Distributions, if any, as and when declared by the General Partner in its sole discretion, shall be made only to Persons who, according to the books and records of the Partnership, were the holders of record of Units on the date determined by the General Partner as of which the Partners are entitled to any such distributions. Notwithstanding anything to the contrary contained in this Agreement, the Partnership, and the General Partner on behalf of the Partnership, shall not be required to make a distribution to any Partner on account of its interest in the Partnership if such distribution would violate the Act or other applicable law. Unless otherwise determined by the General Partner, all distributions of cash shall be made to the Partners in amounts proportionate to the aggregate Net Asset Value of the Units held by the respective Partners on the applicable record date set by the General Partner, except that the amount distributed per Unit of any Class may differ from the amount per Unit of another Class on account of differences in Class-specific expense allocations or for other reasons as determined by the General Partner.

14

(b) Distributions and redemptions made pursuant to this Agreement shall be made in cash. All cash contributions and distributions pursuant to this Agreement shall be made in U.S. dollars (net of applicable currency conversion costs). The “functional currency” of the Partnership shall be the U.S. dollar with respect to all allocations and distributions hereunder.

SECTION 3.3. Performance Participation Allocation.

The General Partner shall be entitled to a distribution (the “Performance Participation Allocation”) from BXINFRA (directly or indirectly through an Intermediate Entity), (i) with respect to the first Reference Period, promptly following the end of the year (which shall accrue on a monthly basis) and (ii) with respect to all subsequent Reference Periods, upon the end of each quarter thereafter and at the other times described below (which shall accrue on a monthly basis) in an amount equal to:

(i) First, if the Total Return for the applicable period exceeds the sum of (i) the Hurdle Amount for that period and (ii) the Loss Carryforward Amount (any such excess, “Excess Profits”), 100% of such Excess Profits until the total amount allocated to the General Partner equals 12.5% of the sum of (x) the Hurdle Amount for that period and (y) any amount allocated to the General Partner pursuant to this clause; and

(ii) Second, to the extent there are remaining Excess Profits, 12.5% of such remaining Excess Profits.

Any amount by which Total Return falls below the Hurdle Amount and that does not constitute Loss Carryforward Amount will not be carried forward to subsequent periods.

The General Partner will also be allocated a Performance Participation Allocation with respect to all Units that are redeemed in connection with repurchases of Units in an amount calculated as described above with the relevant period being the portion of the Reference Period (as defined below) for which such Unit was outstanding, and proceeds for any such Unit repurchase will be reduced by the amount of any such Performance Participation Allocation.

The General Partner may elect to receive the Performance Participation Allocation in cash, Units of the Partnership or any Parallel Fund and/or shares, units or interests (as applicable) of Intermediate Entities (“Unit Allocation”). Such Units may be repurchased at the General Partner’s request and will be subject to the volume limitations of the Partnership’s Unit repurchase program as described in the Memorandum (as amended from time to time, the “Unit Repurchase Program”) but not the early repurchase deduction of the Unit Repurchase Program. Each of the Partnership, Feeder Funds and Parallel Funds will be obligated to pay (without duplication) its proportional share of the Performance Participation Allocation based on its proportional interest in the Aggregator.

After the first Reference Period following the Initial Closing Date, promptly following the end of each calendar quarter that is not also the end of a Reference Period, the General Partner will be entitled to a Performance Participation Allocation as described above calculated in respect of the portion of the year to date, less any Performance Participation Allocation received with respect to prior quarters in that year (the “Quarterly Allocation”). The Performance Participation Allocation that the General Partner is entitled to receive at the end of each Reference Period will be reduced by the cumulative amount of Quarterly Allocations that year.

15

If a Quarterly Allocation is made and at the end of a subsequent calendar quarter in the same Reference Period the General Partner is entitled to less than the previously received Quarterly Allocation(s) (a “Quarterly Shortfall”), then subsequent distributions of any Quarterly Allocations or year-end Performance Participation Allocations in that Reference Period will be reduced by an amount equal to such Quarterly Shortfall, until such time as no Quarterly Shortfall remains. If all or any portion of a Quarterly Shortfall remains at the end of a Reference Period following the application described in the previous sentence, distributions of any Quarterly Allocations and year-end Performance Participation Allocations in the subsequent four Reference Periods will be reduced by (i) the remaining Quarterly Shortfall plus (ii) an annual rate of 5% on the remaining Quarterly Shortfall measured from the first day of the Reference Period following the year in which the Quarterly Shortfall arose and compounded quarterly (collectively, the “Quarterly Shortfall Obligation”) until such time as no Quarterly Shortfall Obligation remains; provided, that the General Partner (or its affiliate) will use the proceeds of any repurchases of its Unit Allocation (excluding Units that have been subsequently distributed to personnel of the General Partner or its affiliates) made after a Quarterly Shortfall Obligation arose to make cash payments to reduce the Quarterly Shortfall and may otherwise make a full or partial cash payment to reduce the Quarterly Shortfall Obligation at any time; provided further, that if any Quarterly Shortfall Obligation remains following such subsequent four Reference Periods, then the General Partner (or its affiliate) will promptly pay the Partnership the remaining Quarterly Shortfall Obligation in cash.

The measurement of the change in Net Asset Value per Unit for the purpose of calculating the Total Return is subject to adjustment by the General Partner to account for any dividend, split, recapitalization or any other similar change in the Partnership’s capital structure or any distributions that the General Partner deems to be a return of capital if such changes are not already reflected in the Partnership’s net assets.

Except as noted above with respect to Quarterly Allocations, the General Partner will not be obligated to return any portion of the Performance Participation Allocation paid due to the subsequent performance of the Partnership.

SECTION 3.4. Tax Distributions. The General Partner may receive a cash advance against distributions of the Performance Participation Allocation to the General Partner to the extent that annual distributions of the Performance Participation Allocation actually received by the General Partner are not sufficient for the General Partner or any of its beneficial owners (whether such interests are held directly or indirectly) to pay when due any income tax (including estimated income tax) imposed on it or them by reason of the allocation to the General Partner of taxable income pursuant to Section 10.4 in respect of the Performance Participation Allocation or such distributions of the Performance Participation Allocation, calculated using the Assumed Income Tax Rate. Amounts of the Performance Participation Allocation otherwise to be distributed to the General Partner pursuant to Section 3.3 (including distributions in kind) shall be reduced on a dollar-for-dollar basis by the amount of any prior advances made to the General Partner pursuant to this Section 3.4 until all such advances are restored to the Partnership in full.

16

SECTION 3.5. Reinvestment. The Partnership may permit any distributions to be reinvested into Units, including pursuant to any reinvestment plan, on terms that the General Partner determines in its sole discretion. The Partnership shall be deemed to have distributed cash to any holder of Units in an amount equal to the amount of any distributions by the Partnership that such holder has elected to be reinvested in Units. The number of Units issued to any such holder in respect of such reinvested distributions shall equal the amount of such reinvested distributions divided by the most recent Net Asset Value per Unit at the time of such distribution.

ARTICLE IV

THE GENERAL PARTNER

SECTION 4.1. Powers of the General Partner. The management, operation and policy of the Partnership shall be vested exclusively in the General Partner, which shall have the power by itself and shall be authorized and empowered on behalf and in the name of the Partnership to carry out any and all of the objects and purposes of the Partnership and to perform all acts and enter into and perform all contracts and other undertakings that it may in its sole discretion deem necessary or advisable or incidental thereto, all in accordance with and subject to the other terms of this Agreement. The Partnership and the General Partner on behalf of the Partnership, may enter into and perform any Subscription Agreement and the Investment Management Agreement, and any documents contemplated therein or related thereto, without any further act, vote or approval of any Person, including any Partner, notwithstanding any other provision of this Agreement. The General Partner is hereby authorized to enter into the documents described in the preceding sentence on behalf of the Partnership, but such authorization shall not be deemed to be a restriction on the power of the General Partner to enter into other documents on behalf of the Partnership. Subject to the express limitations set forth in this Agreement, nothing herein shall restrict the ability of the Partnership to invest alongside or in any Other Blackstone Account and the General Partner is authorized on behalf of the Partnership to engage in any activity not expressly limited herein, including if the Partnership is investing alongside or in such Other Blackstone Account and such activity is permitted under (or otherwise approved in accordance with) the governing terms of such Other Blackstone Account. Notwithstanding the foregoing and the powers and duties included in Section 4.1(a) below, each Limited Partner acknowledges and agrees that the General Partner may rely on investment related decisions relating to the Partnership’s Investments made by the general partner (or similar managing entity) of any Other Blackstone Account alongside or through which the Partnership invests.

(a) Without limiting the foregoing general powers and duties, the General Partner is hereby authorized and empowered on behalf and in the name of the Partnership, or on its own behalf and in its own name, or through agents, as may be appropriate, subject to the limitations contained elsewhere in this Agreement and the Investment Management Agreement, to:

(i) make Investments consistent with the purposes of the Partnership; provided that the General Partner shall not make Primary Commitments to Other Blackstone Accounts that provide for carried interest, management fees or incentive fees to be paid or borne by the Partnership unless such fees result in a dollar-for-dollar reduction of the Management Fee or Performance Participation Allocation payable by the Partnership to its Investment Manager or its General Partner, as applicable (for the avoidance of doubt, this clause shall not restrict Investments that are made in connection with interests in Other Blackstone Accounts purchased on the secondary market as part of a portfolio transaction);

17

(ii) make all decisions concerning the investigation, evaluation, selection, negotiation, structuring, commitment to, monitoring of and disposition of Investments;

(iii) direct the formulation of investment policies and strategies for the Partnership, and select and approve the making of Investments in accordance with this Agreement including in or alongside any Other Blackstone Accounts;

(iv) acquire, hold, sell, transfer, exchange, pledge and dispose of Investments, and exercise all rights, powers, privileges and other incidents of ownership or possession with respect to Investments, including, without limitation, the voting of Investments, the approval of a restructuring of an Investment in a Portfolio Entity, the institution and settlement or compromise of suits and administrative proceedings and other similar matters;

(v) manage Investments generally, including, but not limited to, managing Investments made by the Partnership and the ultimate realization of those Investments and providing, or arranging for the provision of, management or managerial assistance to Portfolio Entities;

(vi) enter into hedging transactions, including interest rate and currency hedging transactions, in connection with the making, disposing or carrying of any Investment;

(vii) enter into derivative transactions, including credit default swaps that relate to the performance of underlying securities that are within the investment objectives of the Partnership, short sales (solely for interest rate and foreign currency hedging purposes), foreign exchange transactions and other derivative contracts or instruments;

(viii) incur all expenditures permitted by this Agreement, and, to the extent that funds of the Partnership are available, pay all expenses, debts and obligations of the Partnership;

(ix) admit an assignee of all or any portion of a Limited Partner’s Units to be an Assignee pursuant to and subject to the terms of Section 8.2;

(x) enter into the Investment Management Agreement with the Investment Manager on behalf of the Partnership and delegate to the Investment Manager certain authority and discretion to act on behalf of the Partnership in making, managing and disposing of the Investments of the Partnership; provided, that the General Partner shall remain ultimately responsible for the management of the Partnership;

(xi) open, maintain and close bank accounts and draw checks or other orders for the payment of money and open, maintain and close brokerage, money market fund and similar accounts;

18

(xii) hire, appoint, remove and replace for usual and customary payments and expenses, consultants, securities and/or futures brokers, depositaries, attorneys, accountants, administrators, advisors, placement agents and such other agents or other service providers for the Partnership as it may deem necessary or advisable in its sole discretion (including the Directors of the Partnership), and authorize any such agent to act for and on behalf of the Partnership;

(xiii) enter into, execute, maintain, file, deliver and/or terminate contracts, undertakings, agreements and any and all other documents, instruments, certificates, reports or statements, or any amendment thereto in the name of the Partnership, and to do or perform all such things as may be necessary or advisable in furtherance of the Partnership’s powers, objects or purposes or to the conduct of the Partnership’s activities, including entering into acquisition agreements to make or dispose of Investments and agreements with respect to borrowings and guarantees by the Partnership which may include such representations, warranties, covenants, indemnities and guaranties as the General Partner deems necessary or advisable;

(xiv) rely on and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties;

(xv) consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it and any act or omission suffered or taken by it on behalf of the Partnership or in furtherance of the interests of the Partnership in good faith in reasonable reliance upon and in accordance with the advice of such counsel, accountants, appraisers, management consultants, investment bankers or other consultants and advisers shall be full justification for any such act or omission, and the General Partner shall be fully protected in so acting or omitting to act;

(xvi) make, in its sole discretion, any and all elections for U.S. federal, state, local and non-United States tax matters, including any election to adjust the basis of Partnership property pursuant to Sections 734(b), 743(b) and 754 of the Code and any election under Section 6226 of the Code, as applicable, or comparable provisions of state, local or non-United States law;

(xvii) modify the organizational structure or entity type of the Partnership (including by merger, consolidation, conversion or similar transaction), structure or restructure the Partnership’s investments and manage the Partnership’s status under the 1940 Act, including, without limitation, electing to rely on a different exclusion from the definition of “investment company” under the 1940 Act or registering the Partnership as an investment company; and

(xviii) authorize and delegate authority to any partner, director, officer, employee or other agent of the General Partner, the Investment Manager or agent or employee of the Partnership to act for and on behalf of the Partnership in all matters related to or incidental to the foregoing.

19

(b) Borrowings and Guarantees.

(i) The General Partner shall have the right, at its option, to cause the Partnership, directly or indirectly through one or more special purpose vehicles, to borrow money from any Person, to make guarantees and provide other credit support to any Person, including on a joint, several, joint and several or cross-collateralized basis with any Feeder Fund, Parallel Fund, Intermediate Entity, Other Blackstone Account or any Person in or alongside which the Partnership acquires, directly or indirectly, or proposes to acquire, an Investment (or to any subsidiary or acquisition vehicle thereof), or incur any other similar credit obligation (including credit support arrangements or other extensions of credit) for any proper purpose relating to the activities of the Partnership.

(ii) The Partnership will not incur indebtedness, directly or indirectly, that would cause the Leverage Ratio to be in excess of 30% (the “Leverage Limit”), provided, that no remedial action will be required if the Leverage Limit is exceeded for any reason other than the incurrence of an increase in indebtedness (including the exercise of rights attached to an Investment); provided further, that the Partnership may incur additional indebtedness for borrowed money that causes the Leverage Ratio to exceed 30% to the extent (x) the General Partner expects at the time of each such incurrence that the Leverage Ratio shall be reduced to less than or equal to 30% within 9 months from the date the Leverage Ratio initially exceeded 30% and (y) a majority of the Independent Directors approve such additional indebtedness as being in the best interests of the Partnership. Any indebtedness incurred by an Intermediate Entity or Portfolio Entity that is not recourse to the Partnership, guarantees of indebtedness, “bad boy” guarantees or other related liabilities that are not recourse indebtedness for borrowed money will be excluded from the calculation of the Leverage Limit. For the avoidance of doubt, for purposes of the foregoing, the refinancing of any amount of existing indebtedness shall not be deemed to constitute the incurrence of new indebtedness so long as no additional amount of net indebtedness is incurred in connection therewith (excluding the amount of transaction expenses associated with such refinancing).

(iii) The General Partner shall have the right to pledge (or cause the Partnership to pledge) any and all of the assets of the Partnership, including Investments. In connection with the Partnership’s Investments alongside (or through) any Other Blackstone Accounts, the Partnership may incur indebtedness, other similar credit obligations or guarantee obligations together with such Other Blackstone Accounts on a joint, several, joint and several or cross-collateralized basis.

(c) Partnership Representative. The General Partner is authorized to appoint or act as a “partnership representative” within the meaning of Section 6223(a) of the Code (and to assume any comparable procedural duties provided under any state, local or non-U.S. tax laws). All expenses incurred by the General Partner while acting in such capacity shall be paid or reimbursed by the Partnership. The determinations of the General Partner with respect to the treatment of any item or its allocation for all tax purposes shall be binding upon all of the Limited Partners so long as such determination shall not be inconsistent with any express term hereof; provided, that the Partnership’s accountants shall not have disagreed therewith.

20

(d) Pre-Closing Investments. The General Partner and/or its Affiliates may make one or more Investments prior to the Initial Closing Date (each, a “Pre-Closing Investment”) that the General Partner determines are appropriate for the Partnership, and in such circumstances the Partnership may acquire interests in such Pre-Closing Investments from the General Partner and/or its Affiliates in accordance with this Section 4.1(d). Notwithstanding anything to the contrary contained herein, it is understood and/or agreed that (i) each Limited Partner, by acquiring Units, shall be deemed to have acknowledged and consented to any actual or potential conflicts of interest relating to any such Pre-Closing Investments, and (ii) each Limited Partner, by executing its Subscription Agreement, shall be deemed to have acknowledged and/or consented to any arrangements and/or transactions relating to the transfer of such Pre-Closing Investments and such Limited Partner’s participation therein to the extent required by applicable law (including, without limitation, for purposes of Section 206(3) of the Advisers Act).

SECTION 4.2. Limitation on Liability.

(a) Notwithstanding anything to the contrary in Section 4.2(b), to the fullest extent permitted by law, none of the Directors, officers of the Partnership, General Partner, the Investment Manager, the partnership representative described in Section 4.1(c), any of their respective Affiliates and the members, partners, officers, directors, employees, agents, stockholders and any Person who serves at the specific request of the General Partner or the Investment Manager on behalf of the Partnership as a member, partner, officer, director, employee or agent of the Partnership or any other entity (each, an “Indemnified Party”) shall be liable to any other Partner or the Partnership for (i) any mistake in judgment, (ii) any action taken or omitted to be taken by the Indemnified Party, which action or omission the Indemnified Party was expressly permitted or required to take or omit pursuant to this Agreement, or (iii) any loss due to the mistake, action, inaction, negligence, dishonesty, fraud or bad faith of any broker or other agent of the Partnership or such Indemnified Party, provided, that such broker or other agent are selected and monitored with reasonable care, in each case of clauses (i), (ii) and (iii) above, unless such action or inaction constituted bad faith, intentional and material breach of this Agreement or the Investment Management Agreement, fraud, willful misconduct or gross negligence of the relevant Indemnified Party.

(b) Notwithstanding anything to the contrary in Section 4.2(a), to the extent that, at law or in equity, the General Partner has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to another Partner, the General 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. Subject to Section 4.2(d), the provisions of this Agreement, to the extent that they expand or restrict the duties and liabilities of the General Partner otherwise existing at law or in equity, are agreed by the Partners to modify to the extent of such other duties and liabilities of the General Partner.

21

(c) The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it and any act or omission suffered or taken by it on behalf of the Partnership or in furtherance of the interests of the Partnership in good faith in reasonable reliance upon and in accordance with the advice of such counsel, accountants, appraisers, management consultants, investment bankers or other consultants and advisers shall be full justification for any such act or omission, and the General Partner shall be fully protected in so acting or omitting to act, provided, that such counsel, accountants, appraisers, management consultants, investment bankers or other consultants and advisers are selected and monitored with reasonable care.

(d) Nothing in this Section 4.2 will be construed so as to provide for the exculpation of any Indemnified Party for any liability (including liability under federal securities laws which, under certain circumstances, impose liability even on persons acting in good faith), to the extent (but only to the extent) that such exculpation would be in violation of applicable law, but otherwise will be construed so as to effectuate these provisions to the full extent permitted by law.

SECTION 4.3. Indemnification.

(a) To the fullest extent permitted by law, the Partnership shall indemnify and hold harmless each Indemnified Party who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including any action by or in the right of the Partnership), from and against any and all claims, losses, liabilities, damages, and expenses of any kind for which such Person has not otherwise been reimbursed to which such Indemnified Party may become subject and arise out of or in connection with the business of the Partnership or any Portfolio Entity or the performance by the Indemnified Party of any of its responsibilities hereunder or under the Investment Management Agreement (including, without limitation, all reasonable costs and expenses of attorneys, defense, appeal and settlement of any and all suits, actions or proceedings instituted or threatened against such Indemnified Party or the Partnership (including, without limitation, formal and informal inquiries, sweep examinations and any type of similar regulatory and/or governmental requests) actually and reasonably incurred by such Person in connection with such action, suit or proceeding) (collectively, “Indemnified Losses”); provided, that an Indemnified Party shall be entitled to indemnification for Indemnified Losses hereunder only to the extent that such Indemnified Losses are not attributable to such Indemnified Party’s intentional and material breach of this Agreement or the Investment Management Agreement, gross negligence, fraud, willful misconduct or bad faith. The satisfaction of any indemnification and any saving harmless pursuant to this Section 4.3(a) shall be from and limited to Partnership assets, no Limited Partner shall have any obligation to make capital contributions to fund its share of any indemnification obligations under this Section 4.3(a) and no Partner shall have any personal liability on account thereof.

(b) Expenses reasonably incurred by an Indemnified Party in defense or settlement of any claim that may be subject to a right of indemnification hereunder shall be advanced by the Partnership prior to the final disposition thereof upon receipt of an undertaking in writing by or on behalf of the Indemnified Party to repay such amount to the extent that it shall be determined ultimately that such Indemnified Party is not entitled to be indemnified hereunder. Notwithstanding the foregoing, no advances shall be made by the Partnership under this Section 4.3(b), without the prior written approval of the General Partner (which may be given or withheld in its sole discretion with respect to any aspect thereof).

22

(c) The right of any Indemnified Party to the indemnification provided herein shall be cumulative of, and in addition to, any and all rights to which such Indemnified Party may otherwise be entitled by contract (including, without limitation, any contract with the Partnership) or as a matter of law or equity and shall extend to such Indemnified Party’s successors, assigns and legal representatives.

(d) Any Indemnified Party entitled to indemnification from the Partnership hereunder shall first seek recovery and diligently pursue such other source under any other indemnity or any insurance policies by which such Person is indemnified or covered, as the case may be, but only to the extent that the indemnitor with respect to such indemnity or the insurer with respect to such insurance policy provides (or acknowledges its obligation to provide) such indemnity or coverage on a timely basis, as the case may be. If an Indemnified Party is a Person other than the General Partner, such Person shall obtain the written consent of the General Partner prior to entering into any compromise or settlement which would result in an obligation of the Partnership to indemnify such Person; and if liabilities arise out of the conduct of the affairs of the Partnership and any other Person for which the Person entitled to indemnification from the Partnership hereunder was then acting in a similar capacity, the amount of the indemnification provided by the Partnership shall be limited to the Partnership’s proportionate share thereof as determined in good faith by the General Partner in light of its fiduciary duties to the Partnership and the Limited Partners.

(e) Nothing in this Section 4.3 will be construed so as to provide for the indemnification of any Indemnified Party for any liability (including liability under federal securities laws which, under certain circumstances, impose liability even on persons acting in good faith), to the extent (but only to the extent) that such indemnification would be in violation of applicable law, but otherwise will be construed so as to effectuate these provisions to the full extent permitted by law.

(f) Notwithstanding anything to the contrary herein, and for the avoidance of doubt, the Partnership’s obligations under this Section 4.3 are not intended to render the Partnership as a primary indemnitor for purposes of the indemnification, advancement of expenses and related provisions under the corporation or other applicable law governing an entity in which the Partnership makes an Investment, it being agreed that an Indemnified Party shall first seek to be so indemnified and have such expenses advanced by such entity (or applicable insurance policies maintained by such entity). Inasmuch as the Partnership is intended to be secondarily liable in respect of losses, damages and expenses that are otherwise primarily indemnifiable by a particular entity in which the Partnership makes an Investment, it is intended among the Partners and the Indemnified Party that any advancement or payment by the Partnership to the Indemnified Party will result in the Partnership having a subrogation claim against the relevant entity in respect of such advancement or payments. The General Partner and the Partnership shall be specifically empowered to structure any such advancement or payment as a loan or other arrangement as the General Partner may determine necessary or advisable to give effect to or otherwise implement the foregoing.

23

SECTION 4.4. General Partner as Limited Partner. The General Partner may also be a Limited Partner, including but not limited to the extent that it purchases Units, elects to receive all or a portion of the Performance Participation Allocation in Units, or becomes a transferee of all or any part of the Units of a Limited Partner, and to such extent shall be treated as a Limited Partner in all respects, except as provided below. Any Units held by Blackstone or an Affiliate of the Investment Manager or the General Partner may bear no or reduced Management Fees, Servicing Fees or the Performance Participation Allocation (in the manner each such Partner and the General Partner shall agree upon such Partner’s admission to the Partnership, including pursuant to a rebate of such amounts).

SECTION 4.5. Other Activities.

(a) Comparable Funds. The General Partner and/or its Affiliates shall be permitted to close on one or more other investment vehicles, managed accounts and/or other similar arrangements (including those that may be structured through a fund or as one or more entities), for the benefit of one or more other investors having the same or similar investment objective as the Partnership and having terms as determined by the General Partner in its sole discretion (such vehicles, managed accounts and arrangements, collectively, “Comparable Funds”) and such Comparable Funds may invest alongside or in lieu of the Partnership as provided in Section 4.5(c). In addition, each Limited Partner acknowledges and agrees that (i) nothing herein shall limit the ability of the General Partner to sponsor, raise, close and manage any such Comparable Funds and (ii) by virtue of such Comparable Funds and/or the Other Blackstone Accounts, the General Partner and its Affiliates will be presented with investment opportunities that fall within the investment objective of the Partnership, Other Blackstone Accounts and the Comparable Funds, and in such circumstances, the General Partner and its Affiliates shall allocate such opportunities among the Partnership, such Other Blackstone Accounts and/or the Comparable Funds as described more fully in Section 4.5(c).

(b) Business with Certain Affiliates. The Limited Partners recognize and consent that the General Partner or Affiliates of the General Partner may receive various types of fees in connection with the investment activities of BXINFRA and/or Portfolio Entities and from unconsummated transactions, including, without limitation, net break-up and topping fees, commitment fees, transaction fees, monitoring fees, directors’ fees, investment banking fees, construction, development and other property/asset management fees, mortgage servicing fees, consulting fees (including management consulting), syndication fees, capital markets syndication and advisory fees (including underwriting fees, and with respect to syndications or placements of debt and/or equity securities or instruments issued by portfolio entities or entities formed to invest therein), origination fees, servicing (including loan/mortgage/asset servicing) fees, healthcare consulting/brokerage fees, group purchasing fees and/or insurance (including title insurance), financial advisory fees, organization fees, financing fees, divestment fees and other similar fees, fees for environmental, social and corporate governance (“ESG”) services, data management and services fees or payments, leasing/administrative fees, similar fees for arranging acquisitions and other financial restructurings, other similar operational and financial matters, (whether in cash or in-kind), other fees and annual retainers (whether in cash or in-kind) and any other fees as further described in the Memorandum as updated from time to time from or with respect to Persons in which the Partnership acquires or holds Investments and/or other Persons (including co-investors and/or joint venture partners), and neither the Partnership nor any Limited Partner shall have any interest therein by virtue of this Agreement or the partnership relationship created hereby. Notwithstanding this Section 4.5, the General Partner or any of its Affiliates may, but shall not be required to, make advances to the Partnership, which advances shall accrue interest comparable to those received by a third party in an arm’s length transaction and shall be repaid from any funds of the Partnership.

(c) Allocation of Investment Opportunities. The General Partner will determine in its sole discretion whether an investment opportunity is within the investment objectives of the Partnership. Each Limited Partner recognizes and consents that all or any portion of an investment opportunity that the General Partner determines in its sole discretion is not appropriate for the Partnership or is more appropriate for an Other Blackstone Account may be pursued by the General Partner and its Affiliates outside of the Partnership. Each Limited Partner acknowledges that Blackstone currently invests third-party capital in a wide variety of investment opportunities on a global basis through its various investment funds (including Other Blackstone Accounts), some of which will have investment objectives that overlap with those of the Partnership. Other Blackstone Accounts that have investment objectives or guidelines that overlap with those of the Partnership may receive priority with respect to any investment opportunity that falls within such common objectives or guidelines or such investment opportunity may be allocated in any manner deemed appropriate by Blackstone in its sole discretion.

(d) Except as provided in Sections 4.5(a)-(c) above, this Agreement shall not be construed in any manner to preclude the General Partner, the Investment Manager or any of their respective direct or indirect partners, members or stockholders or their respective officers, directors, employees or Affiliates from engaging in any activity whatsoever to the maximum extent permitted by applicable law.

SECTION 4.6. Valuation.

The General Partner will be responsible for the valuation of Units which it will determine in accordance with the Partnership’s valuation policies, as updated from time to time.

THE LIMITED PARTNERS

SECTION 5.1. Management.

Except as expressly provided in this Agreement, no Limited Partner shall have the right or power to vote or participate in the management or affairs of the Partnership, nor shall any Limited Partner have the power to sign for or bind the Partnership. The exercise by any Limited Partner of any right conferred herein shall not be construed to constitute participation by such Limited Partner in the control of the business of the Partnership so as to make such Limited Partner liable as a general partner for the debts and obligations of the Partnership for purposes of the Act. To the fullest extent permitted by law, no Limited Partner owes any duty (fiduciary or otherwise) to the Partnership or any other Partner as a result of such Limited Partner’s status as a Limited Partner, other than to act in good faith (to the extent required by law); provided, that this in no way limits any express obligations of a Limited Partner provided for herein or in such Limited Partner’s Subscription Agreement.

25

SECTION 5.2. Liabilities of the Limited Partners.

Except as provided by the Act or other applicable law and subject to the obligations to indemnify the Partnership and the General Partner as provided in Section 10.6 and as otherwise expressly set forth herein, no Limited Partner shall have any personal liability whatsoever in its capacity as a Limited Partner, whether to the Partnership, to any of the Partners, or to the creditors of the Partnership, for the debts, liabilities, contracts, or other obligations of the Partnership or for any losses of the Partnership.

SECTION 5.3. Independent Directors; Board of Directors.

(a) The General Partner shall have the authority to appoint directors, including one or more directors that would be independent under the tests set out in Rule 303A.02 of the New York Stock Exchange Listed Company Manual or other policy as determined by the General Partner (each of the independent directors, an “Independent Director,” and together with the other directors, the “Board of Directors,” each, individually, a “Director”); provided that the appointment of new Independent Directors as a result of vacancy (regardless of how the vacancy was created) will require approval by the Board of Directors, including a majority of the remaining Independent Directors. No later than 90 days after the Initial Closing Date, at least one half of the Board of Directors will consist of Independent Directors. Commencing 180 days following the Initial Closing Date and continuing thereafter, a majority of the Board of Directors will consist of Independent Directors; provided that, if an Independent Director departs the Board of Directors by reason of death, disqualification, removal or resignation or ceases to be an Independent Director, this requirement will be suspended for a period not to exceed 90 days. The Independent Directors shall be unaffiliated with the General Partner, the Investment Manager, or any of their Affiliates. A majority of the Independent Directors are authorized to give or withhold the Partnership’s consent or approval as an “independent client representative” with respect to matters required by Section 206(3) of the Advisers Act and certain other situations involving conflicts of interest, including with regards to the assignment or other transfer of the General Partnership Interest pursuant to Section 8.1 (in each case where presented to such Independent Directors in the General Partner’s sole discretion) (the “ICR”). In addition, all transactions involving (i) the purchase or sale of assets or (ii) any extension of credit, in each case, to or by the Partnership or any Intermediate Entity, on the one hand, and the General Partner, the Investment Manager, any of their Affiliates or any directly or indirectly controlled portfolio entities of Other Blackstone Accounts, on the other hand, shall be presented to the Independent Directors and, if the Independent Directors deem it appropriate, in their sole discretion, may be approved by the Independent Directors; provided, however, that (i) purchases of loans in the secondary market and (ii) primary commitments (x) from short-term borrowings (less than 90 days) on arms’ length terms and (y) that comply with the ICR framework for debt instruments approved by the Independent Directors shall not be presented to the Independent Directors. All transactions involving (i) the purchase or sale of assets or (ii) the extension of credit, in each case, to or by a Portfolio Entity of the Partnership, on the one hand, and a directly or indirectly controlled portfolio entity of an Other Blackstone Account, shall be conducted on terms that are fair and reasonable to the Fund, on terms and conditions no less favorable to the Fund than could be obtained from unaffiliated third parties and consistent with the best interests of the Fund (each as determined in the sole discretion of the General Partner to the extent not presented to the Independent Directors for review and approval). Each Limited Partner agrees that, with respect to any consent sought

26

from the Independent Directors under this provision, such consent of the Independent Directors shall be binding upon the Partnership, and the General Partner and its Affiliates, acting in accordance with or pursuant to such consent (or such procedures or standards approved by the Independent Directors), shall, absent actual fraud or willful misconduct, be fully protected and justified in acting in reliance upon and in accordance with such consent of the Independent Directors. Any matters for which the Board of Directors or Independent Directors have authority to act can be effected by majority approval of the Board of Directors or Independent Directors, as applicable. If there are only two Independent Directors, matters requiring consent or approval of a majority of the Independent Directors will require approval of both Independent Directors. Subject to the foregoing, the General Partner shall have the right to change or replace any Independent Director for Cause and any Director that is not an Independent Director with our without Cause.

(b) Approval of the Independent Directors shall be required for (i) the suspension of (x) the calculation of the Net Asset Value of the Units, (y) the Partnership’s offering of Units pursuant to the Memorandum or (z) the Unit Repurchase Program, (ii) any material modification to (x) the Partnership’s valuation policies and (y) the Unit Repurchase Program and (iii) fair valuation of any investment in a company or other private asset of the Partnership that the General Partner has determined to value outside of the applicable range provided by the Partnership’s independent valuation advisor. The General Partner will present to the Board of Directors the basis for any such proposed suspension or modification and will notify the Independent Directors of any change in the independent valuation advisor.

(c) The Board of Directors (including the Independent Directors) shall owe a fiduciary duty to use their reasonable business judgment to act in the best interests of the Partnership with respect to matters of the Partnership that are within the Board of Directors’ authority.

The General Partner may, to the extent applicable, hold all or any portion of any Subscription made by a Feeder Fund pursuant to the preceding sentence in reserve and apply such amounts any time to satisfy any such expenses, obligations, indemnities or liabilities, contingent or otherwise, relating to such Feeder Fund.

SECTION 8.2. Assignments/Substitutions by Limited Partners.

(a) A Limited Partner may not directly or indirectly sell, exchange, assign, mortgage, hypothecate, pledge or otherwise transfer its Units (or any interest therein) in whole or in part to any Person (an “Assignee”) unless:

(i) such assignment or transfer would not violate the Securities Act or any state securities or “Blue Sky” laws applicable to the Partnership or the Units to be assigned or transferred;

33

(ii) such assignment or transfer would not cause the Partnership to lose its status as a partnership for U.S. federal income tax purposes or cause the Partnership to become required to register under the 1940 Act;

(iii) such assignment or transfer would not otherwise cause the Partnership to violate any applicable law, regulation, court order or judicial decree; and

(iv) such assignment or transfer would not cause the Partnership to be treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code and the regulations promulgated thereunder, and to achieve this purpose, the Partnership will not permit transfers (x) more frequently than quarterly, (y) without receiving 60 days’ (or such reasonably shorter period as is agreed to by the General Partner) written notice from or on behalf of an assigning or transferring Limited Partner and (z) in excess of 2% of the aggregate number of Units in any Fiscal Year (which limitation may be increased or decreased by the General Partner upon the advice of counsel).

(d) Any attempted assignment or substitution not made in accordance with this Section 8.2 shall be deemed cancelled.

Notwithstanding Section 8.4, the General Partner may cause the Partnership to establish, from time to time, a program or programs by which the Partnership voluntarily offers to repurchase Units from Partners from time to time, including pursuant to tender offers in accordance with the requirements of Rule 13e-4 under the 1934 Act, as applicable, including through the Unit Repurchase Program; provided, that such repurchases do not impair the capital or operations of the Partnership or cause the Partnership to become subject to tax as a corporation.

SECTION 10.1. Capital Accounts.

(a) A separate capital account (the “Capital Account”) shall be established and maintained for each Partner in accordance with the principles and requirements set forth in Section 704(b) of the Code and the Treasury Regulations. The Capital Account of each Partner shall be credited with such Partner’s Subscription to the Partnership, as well as any concurrent or subsequent contributions to capital, all Profits allocated to such Partner pursuant to Section 10.2 and any items of income or gain which are specially allocated pursuant to Section 10.3 or otherwise pursuant to this Agreement; and shall be debited with all “Losses” allocated to such Partner pursuant to Section 10.2, any items of loss or deduction of the Partnership specially allocated to such Partner pursuant to Section 10.3 or otherwise pursuant to this Agreement, and all cash and the Carrying Value of any property (net of liabilities assumed by such Partner and the liabilities to which such property is subject) distributed by the Partnership to such Partner. To the extent not provided for in the preceding sentence, the Capital Accounts of the Partners shall be adjusted and maintained in accordance with the rules of Treasury Regulations Section 1.704-1(b)(2)(iv), as the same may be amended or revised. Any references in any section of this Agreement to the Capital Account of a Partner shall be deemed to refer to such Capital Account as the same may be credited or debited from time to time as set forth above. In the event of any transfer of any interest in the Partnership in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of the transferor to the extent it relates to the transferred interest. In furtherance of the foregoing and in accordance with Treasury Regulation §1.1061-3(c)(3)(ii)(B), the Partnership shall, (i) calculate separate allocations attributable to (A) the Performance Participation Allocation and any other distribution entitlements that are not commensurate with capital contributed to the Partnership, and (B) any distribution entitlements of the Partners that are commensurate with capital contributed to the Partnership (in each case, within the meaning of Treasury Regulation §1.1061-3(c)(3)(ii)(B) and as reasonably determined by the General Partner), and (ii) consistently reflect each such allocation in its books and records.

SECTION 10.2. Allocations of Profits and Losses. Except as otherwise provided in this Agreement, Profits, Losses and, to the extent necessary, individual items of income, gain, loss or deduction of the Partnership shall be allocated among the Partners in a manner such that, after giving effect to the special allocations set forth in Sections 10.3(d), (e), (f), (g), or elsewhere expressly provided for in this Agreement or the Investment Management Agreement, the Capital Account of each Partner, immediately after making such allocation, is, as nearly as possible, equal (proportionately) to (i) the distributions that would be made to such Partner pursuant to this Agreement if the Partnership were dissolved, its affairs wound up and its assets sold for cash equal to their Carrying Value, all Partnership liabilities were satisfied (limited with respect to each nonrecourse liability to the Carrying Value of the assets securing such liability), and the net assets of the Partnership were distributed in accordance with this Agreement to the Partners immediately after making such allocation, minus (ii) such Partner’s share of Partnership Minimum Gain and Partner Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets. Notwithstanding the foregoing, the General Partner may make such allocations as it deems reasonably necessary to give economic effect to the provisions of this Agreement, taking into account such facts and circumstances as it deems reasonably necessary for this purpose.

SECTION 10.3. Special Allocation Provisions. Notwithstanding any other provision in this Article X:

(a) Minimum Gain Chargeback. If there is a net decrease in Partnership Minimum Gain or Partner Nonrecourse Debt Minimum Gain (determined in accordance with the principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during any partnership taxable year, the Partners shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The items to be so allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section 10.3(a) is intended to comply with the minimum gain chargeback requirements in such Treasury Regulations Sections and shall be interpreted consistently therewith; including that no chargeback shall be required to the extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4).

(b) Qualified Income Offset. In the event any Limited Partner unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be specially allocated to such Limited Partner in an amount and manner sufficient to eliminate the deficit balance in its Capital Account created by such adjustments, allocations or distributions as promptly as possible; provided, that an allocation pursuant to this Section 10.3(b) shall be made only to the extent that a Partner would have a deficit balance in its Adjusted Capital Account Balance in excess of such sum after all other allocations provided for in this Article X have been tentatively made as if this Section 10.3(b) were not in this Agreement. This Section 10.3(b) is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith.

37

(c) Gross Income Allocation. In the event any Limited Partner has a deficit Capital Account at the end of any Fiscal Year which is in excess of the sum of (i) the amount such Partner is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Limited 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 10.3(c) shall be made only if and to the extent that a Limited Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article X have been tentatively made as if Section 10.3(b) and this Section 10.3(c) were not in this Agreement.

(d) General Partner Expenses. To the extent, if any, that General Partner Expenses and any items of loss, expense or deduction resulting therefrom are deemed to constitute items of Partnership loss or deduction rather than items of loss, or deduction of the General Partner, such General Partner Expenses and other items of loss, expense or deduction shall be allocated 100% to the General Partner and the General Partner’s Capital Account shall be credited with the same amount.

(e) Payee Allocation. In the event any payment to any Person that is treated by the Partnership as the payment of an expense is recharacterized by a taxing authority as a Partnership distribution to the payee as a partner, such payee shall be specially allocated an amount of Partnership gross income and gain as quickly as possible equal to the amount of the distribution.

(f) Nonrecourse Deductions. Nonrecourse Deductions shall be allocated pro rata based on the number of Units held by each Partner.

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

(h) Special Allocations. Any special allocations of income, gain, loss, deduction or credit pursuant to Section 10.3(b) or (c) hereof shall be taken into account in computing subsequent allocations pursuant to this Article X, so that the net amount of any items so allocated and all other items allocated to each Partner shall, to the extent possible, be equal to the net amount that would have been allocated to each Partner if such allocations pursuant to Sections 10.3(b) or (c) had not occurred.

38

SECTION 10.4. Tax Allocations. For income tax purposes only, each item of income, gain, loss and deduction of the Partnership shall be allocated among the Partners in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided, that in the case of any Partnership asset the Carrying Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated solely for income tax purposes in accordance with the principles of Sections 704(b) and (c) of the Code (in any manner determined by the General Partner) so as to take account of the difference between Carrying Value and adjusted basis of such asset. Notwithstanding the foregoing, the General Partner may make such allocations as it deems reasonably necessary to give economic effect to the provisions of this Agreement, taking into account such facts and circumstances as it deems reasonably necessary for this purpose. The General Partner shall determine all matters concerning allocations for tax purposes not expressly provided for herein in its sole discretion. To the extent there is an adjustment by a taxing authority to any item of income, gain, loss, deduction or credit of the Partnership (or an adjustment to any Partner’s distributive share thereof), the General Partner may reallocate the adjusted items among each Partner or former Partner (as determined by the General Partner) in accordance with the final resolution of such audit adjustment.

SECTION 10.5. Other Allocation Provisions. The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such regulations. Sections 10.2 to 10.5 may be amended at any time by the General Partner if necessary, to maintain substantial economic effect in accordance with such regulations or to ensure that allocations are in accordance with the Partners’ interests in the Partnership, in each case as reasonably determined by the General Partner and so long as any such amendment does not materially change the relative economic interests of the Partners.

SECTION 10.6. Tax Advances. To the extent the General Partner reasonably determines that the Partnership (or any entity in which the Partnership holds an interest) is or may be required by law to withhold or to make tax payments (including interest and penalties thereon) on behalf of or with respect to any Partner or as a result of a Partner’s participation in the Partnership or as a result of a Partner’s failure to provide requested tax information, including any withholding taxes or any amounts imposed pursuant to FATCA, Section 6225 or Section 1446(f) of the Code (“Tax Advances”), the General Partner may withhold or escrow such amounts or make such tax payments as so required. All Tax Advances attributable to a Partner shall, at the option of the General Partner, (i) be promptly paid to the Partnership by the Partner on whose behalf such Tax Advances were made or (ii) be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Partner or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation of the Partnership otherwise payable to such Partner. Whenever the General Partner selects the option set forth in clause (ii) of the immediately preceding sentence for repayment of a Tax Advance by a Partner, for all other purposes of this Agreement such Partner shall be treated as having received all distributions unreduced by the amount of such Tax Advance. Each Partner hereby agrees to indemnify and hold harmless the Partnership, the General Partner, their Affiliates and their respective members, officers, directors, employees, agents, stockholders or partners, from and against any liability (including, without limitation, any liability for taxes, penalties, additions to tax or interest) with respect to income attributable to or distributions or other payments to such Partner, any Tax Advances required on behalf of or with respect to such Partner or as a result of such Partner’s failure to provide any tax information reasonably requested by the General Partner, although the foregoing in no way limits the provisions of Section 4.2(a). In the event the Partnership is liquidated and a liability or claim is asserted against, or an expense is borne by, the General Partner, any of their Affiliates or any of their respective members, officers, directors, employees, agents, stockholders or partners for Tax Advances made or required to be made, such parties shall have the right to be reimbursed from the Limited Partner on whose behalf such Tax Advance was made. The obligations of a Partner set forth in this Section 10.6 shall survive the withdrawal of any Partner from the Partnership, any transfer of a Partner’s Units or the liquidation or dissolution of the Partnership.

39

SECTION 10.7. Tax Filings. Each Limited Partner shall provide such cooperation and assistance, including but not limited to executing and filing forms or other statements, as is reasonably requested by the General Partner to enable the Partnership or any entity in which the Partnership owns a direct or indirect interest to satisfy any applicable tax reporting or compliance requirements or to qualify for an exception from or reduced rate of tax or other tax benefit or be relieved of liability for any tax.

SECTION 10.8. Tax Considerations. The General Partner will use reasonable efforts to cause the Partnership to structure its direct and indirect investments in jurisdictions outside of the United States and to conduct the operations of the Partnership so as to avoid any Limited Partner (i) having a “permanent establishment” (or other taxable nexus) in any non-U.S. jurisdiction which causes the Limited Partner to become subject to tax in any non-U.S. jurisdiction in respect of income not derived from the Partnership, or to become subject to tax in any non-U.S. jurisdiction on a net income basis in respect of income derived from the Partnership, or (ii) being required, in its own capacity, to file any tax returns in any non-U.S. jurisdiction (other than any such filings required to obtain refunds of amounts withheld or to avoid withholding), in each case solely as a result of the Limited Partner having invested in the Partnership.

ARTICLE XI

MISCELLANEOUS

SECTION 11.1. Waiver of Partition and Accounting. Except as may be otherwise required by law in connection with the winding-up, liquidation and dissolution of the Partnership, each Partner hereby irrevocably waives any and all rights that it may have to maintain an action for an accounting or for partition of any of the Partnership’s property.

SECTION 11.2. [Reserved.]

SECTION 11.3. Amendments; Certain Consents.

(a) Except as required by law, this Agreement may be amended, modified or supplemented, and any provision herein may be waived, by the written consent of the General Partner (including an amendment in the form of a merger, consolidation, conversion or similar transaction into a successor entity to the Partnership); provided that any amendment, modification or supplement that is viewed by the General Partner in its discretion, as a whole together with all

40

such amendments, modifications or supplements, as having a material adverse effect on the Limited Partners in the aggregate will require the approval of the Independent Directors and will not take effect until the Limited Partners have received notice of such amendment (including through a 1934 Act report) and, following receipt of such notice, at least two repurchase offers of Units has taken place.

(b) Notwithstanding the foregoing, this Agreement may be amended by the General Partner without the consent of the Limited Partners to address changes in tax, regulatory or other similar legislation, including changes in tax laws relating to “carried interest,” which adversely affect the U.S. federal, state or local tax treatment of the Performance Participation Allocation distributions to the General Partner or its direct or indirect owners and which would not add to the obligations (including any tax liabilities) of any Limited Partner or otherwise alter any of the rights (including entitlements to distributions or any other economic rights) of such Limited Partner without the consent of such Limited Partner.

(c) Alternatively, in the case of any consent sought by the General Partner under this Agreement (including, without limitation, with respect to any proposed amendment of this Agreement or any anticipated “assignment” (within the meaning of the Advisers Act) by the General Partner of its Units or by the Investment Manager of the Investment Management Agreement), the General Partner may also determine that the consent of any percentage in Units of the Limited Partners may also be given and/or obtained as follows:

(i) At least 45 days prior to the proposed effective date of such consent, the General Partner shall give written notice to each Limited Partner of such matter and shall request such Limited Partner to indicate in writing whether or not it consents thereto. If any Limited Partner has not indicated in writing within 30 days (or such longer period as the General Partner may specify in its sole discretion) after such notice whether or not it consents to such matter, the General Partner shall promptly provide a second notice to such Limited Partner of such matter and shall again request such Limited Partner to indicate in writing whether or not it consents thereto and shall prominently state in such second notice that if the Limited Partner does not indicate in writing within 14 days (or such longer period as the General Partner may specify in its sole discretion) after such second notice (the end of such fourteenth (14) day or longer period after such notice, the “Notice Date”) whether or not it consents to such matter, such Limited Partner shall be deemed to have consented to such amendment. Any Limited Partner that does not indicate whether or not it consents to such matter by the Notice Date shall be deemed to have consented to such matter. At any time on or prior to the Notice Date, a Limited Partner may indicate that it does or does not consent to such matter, but after the Notice Date any indication by a Limited Partner that it does not consent to such matter shall not be effective for purposes of the foregoing.

(ii) The consent of a particular percentage of Net Asset Value represented by Units of the Limited Partners with respect to such matter shall have been received if at any time prior to the Notice Date Limited Partners representing such percentage in Units of the Limited Partners have affirmatively consented to such matter or if as of the Notice Date Limited Partners representing such percentage in Units of the Limited Partners have either affirmatively consented to such matter or are deemed to have consented to such matter as provided above.

41

(d) The General Partner shall have the right to amend this Agreement without the approval of any other Partner to the extent the General Partner reasonably determines, based upon written advice of outside tax counsel to the Partnership, that the amendment is necessary to provide assurance that the Partnership will not be treated as a “publicly traded partnership” under Section 7704 of the Code and the regulations promulgated thereunder.

(e) The General Partner shall have the right, on or before the effective date of final regulations, to amend, as determined by the General Partner in good faith, this Agreement to provide for the election of a safe harbor under United States Treasury Regulations Section 1.83-3(l) (or any similar provision) under which the fair market value of any Units that are transferred in connection with the performance of services is treated as being equal to the liquidation value of that interest, an agreement by the Partnership and all of its Partners to comply with the requirements set forth in such regulations and IRS Notice 2005-43 (and any other guidance provided by the IRS with respect to such election) with respect to all Units transferred in connection with the performance of services while the election remains effective, and any other amendments reasonably related thereto or reasonably required in connection therewith; provided, that if such amendment, in the General Partner’s reasonable opinion, would be materially adverse to the economic interests of the Limited Partners, such amendment will require the consent of each Partner materially adversely affected thereby.

(f) Upon obtaining such approvals required by this Agreement and without any further action or execution by any other Person, including any Limited Partner, (i) any amendment, restatement, modification or waiver of this Agreement shall be implemented and reflected in a writing executed solely by the General Partner which shall be provided to the Limited Partners pursuant to Section 11.6 herein and (ii) the Limited Partners, and any other party to this Agreement, shall be deemed a party to and bound such amendment, restatement, modification or waiver of this Agreement.

SECTION 11.4. Entire Agreement. Unless otherwise agreed by the General Partner in writing, this Agreement and the other agreements referred to herein constitute the entire agreement among the Partners and between the Partners and the Initial Limited Partner with respect to the subject matter hereof and supersede any prior agreement or understanding among or between them with respect to such subject matter. The representations and warranties of the Limited Partners in, and the other provisions of, the Subscription Agreements shall survive the execution and delivery of this Agreement.

SECTION 11.5. Severability. Each provision of this Agreement shall be considered severable and if for any reason any provision which is not essential to the effectuation of the basic purposes of this Agreement is determined by a court of competent jurisdiction to be invalid or unenforceable and contrary to the Act or existing or future applicable law, such invalidity shall not impair the operation of or affect those provisions of this Agreement which are valid. In that case, this Agreement shall be construed so as to limit any term or provision so as to make it enforceable or valid within the requirements of any applicable law, and in the event such term or provision cannot be so limited, this Agreement shall be construed to omit such invalid or unenforceable provisions.

42

SECTION 11.6. Notices.

(a) Any notice to any Limited Partner shall be at the address or electronic mail address of such Partner set forth in such Limited Partner’s Subscription Agreement or such other mailing address or electronic mail address of which such Limited Partner shall advise the General Partner or transfer agent in writing.

SECTION 11.7. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware and, in particular, the provisions of the Act, shall govern the validity of this Agreement, the construction of its terms and interpretation of the rights and duties of the parties.

SECTION 11.8. Jurisdiction; Venue; Trial by Jury.

(a) Any action or proceeding against the parties relating in any way to this Agreement shall be brought and enforced in the courts of the State of Delaware, to the extent subject matter jurisdiction exists therefor, of the United States for the District of Delaware, and the parties irrevocably submit to the jurisdiction of both such courts in respect of any such action or proceeding. For the avoidance of doubt, unless the General Partner consents in writing to the selection of an alternative forum, to the fullest extent permitted by law, any action or proceeding arising under the federal securities laws, including the rules and regulations promulgated thereunder, shall be brought and enforced in the federal district courts of the United States for the District of Delaware. The parties irrevocably waive, to the fullest extent permitted by law, any objection that they may now or hereafter have to the laying of venue of any such action or proceeding in the courts of the State of Delaware or the United States District Court for the District of Delaware and any claim that any such action or proceeding brought in any such court has been brought in any inconvenient forum.

(b) Each Partner and the Partnership waives, and covenants that such Partner and the Partnership shall not assert (whether as plaintiff, defendant or otherwise), any right to trial by jury in any forum in respect of any issue, claim or proceeding arising out of this Agreement or the subject matter hereof or in any way connected with the dealings of any Partner or the Partnership or any of its Affiliates in connection with any representation, warranty, covenant or agreement contained in this Agreement or any transaction contemplated by this Agreement, in each case whether now existing or hereafter arising and whether in contract, tort or otherwise. The Partnership or any Partner may file an original counterpart or a copy of this Section 11.8(b) with any court in any jurisdiction as written evidence of the consent of the Partners to the waiver of their respective rights to trial by jury.

43

Except with respect to the rights of an Indemnified Party hereunder, none of the provisions of this Agreement shall be for the benefit of or enforceable by the creditors of the Partnership. This Agreement shall be binding upon and inure to the benefit of the Partners, the Initial Limited Partner and their legal representatives, heirs, successors and permitted assigns.

SECTION 11.10. No Waiver. No failure on the part of the General Partner to exercise, and no delay on its part in exercising, any right or remedy under this Agreement shall operate as a waiver of such right or remedy, nor shall any single or partial exercise of any right or remedy under this Agreement preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies provided by law.

SECTION 11.11. Counterparts and Execution.

All such counterparts shall constitute one and the same document. For the avoidance of doubt, a Person’s execution and delivery of this Agreement (or any agreement, document or notice required or permitted by this Agreement, or any amendment to this Agreement) by electronic signature and/or electronic transmission shall constitute the execution and delivery of a counterpart of the executed document by or on behalf of such Person and shall bind such Person to its terms. The authorization under this paragraph may include, without limitation, a manually signed paper document which has been converted into electronic form (such as scanned into PDF format or transmitted via facsimile), or an electronically signed document converted into another format, for transmission, delivery and/or retention. Any Person executing and delivering this Agreement or any document electronically further agrees to take any and all reasonable additional actions, if any, evidencing its intent to be bound by the terms of this Agreement or other such document, as may be reasonably requested by the General Partner.

44

SECTION 11.13. Interpretation; Compliance with Laws.

(a) Wherever from the context it appears appropriate, each term stated in either the singular or the plural shall include the singular and the plural, and pronouns stated in either the masculine or the neuter gender shall include the masculine, the feminine and the neuter. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation.”

(b) Whenever in this Agreement a Person is permitted or required to make a decision (i) in its “sole discretion,” “sole and absolute discretion” or “discretion” or under a grant of similar authority or latitude, the Person shall be entitled to consider any interests and factors as it desires, including its own interests, or (ii) in its “good faith” or under another express standard, the Person shall act under such express standard and shall not be subject to any other or different standards imposed by this Agreement or any other agreement contemplated herein or by relevant provisions of law or in equity or otherwise, and, in connection with the foregoing, the term “good faith” shall have the meaning ascribed to such term under Delaware contract law. In no way does this Section 11.13(b) eliminate or modify the General Partner’s implied contractual covenant of good faith and fair dealing.

SECTION 11.14. Partnership Tax Treatment. The Partners intend for the Partnership to be treated as a partnership for U.S. federal income tax purposes and no election to the contrary shall be made unless the General Partner in its sole discretion determines that other treatment or election is in the best interests of the Partnership.

(a) Except as otherwise required by law, including, without limitation, any public disclosure law relating to governmental entities, each Limited Partner will maintain the confidentiality of information which is Non-Public Information received by such Limited Partner pursuant to this Agreement in accordance with such procedures as it applies generally to information of this kind, and shall use such Non-Public Information solely in connection with monitoring such Limited Partner’s investment in the Partnership or otherwise with respect to their Units and agrees in that regard not to trade in securities on the basis of any such information. All communications between the General Partner or the Investment Manager, on the one hand, and any Limited Partner, on the other, shall be presumed to include confidential, proprietary, trade secret and other sensitive information; provided, that the foregoing shall not limit the ability of any Limited Partner to furnish any such information to (i) its Affiliates or advisors or (ii) examiners, auditors, inspectors, attorneys, or persons with similar responsibilities or duties of a nationally recognized industry self-regulatory association, federal or state regulatory body or federal, state or local taxation authority; provided, further, that such Limited Partner shall be liable to the Partnership and the General Partner for any such Affiliate’s or advisor’s failure to comply with the foregoing (unless such Limited Partner receives a written undertaking from such Affiliate or advisor to maintain the confidentiality of such information). The Partners hereby acknowledge that pursuant to § 17-305(f) of the Act the rights of a Limited Partner to obtain information from the Partnership shall be limited to only those rights expressly provided for in this Agreement, and that any other rights provided under § 17-305(a) of the Act shall not be available to the Limited Partners or applicable to the Partnership.

45

(b) Notwithstanding anything in this Agreement to the contrary, to comply with Treasury Regulations Section 1.6011-4(b)(3), each Limited Partner (and any employee, representative or other agent of such Limited Partner) may disclose to any and all Persons, without limitation of any kind, the U.S. federal tax treatment and tax structure of the Partnership or any transactions contemplated by the Partnership, it being understood and agreed, for this purpose (i) the name of, or any other identifying information regarding, (A) the Partnership or any existing or future investor (or any Affiliate thereof) in the Partnership, or (B) any investment or transaction entered into by the Partnership, (ii) any performance information relating to the Partnership or its Investments or (iii) any performance or other information relating to other investments sponsored by the General Partner, the Investment Manager or their Affiliates, does not constitute such tax treatment or structure information.

(d) Any obligation of a Limited Partner pursuant to this Section 11.15 may be waived by the General Partner in its sole discretion.

(e) Notwithstanding anything to the contrary herein, nothing in this Agreement (including paragraphs 11.15(a)-(d) above and/or any other agreement regarding the Limited Partner’s interest in the Partnership prohibits or restricts any individual from reporting possible violations of federal, state or local law or regulation to any governmental agency or regulatory authority (including but not limited to the Securities and Exchange Commission) and/or cooperating with any such governmental agency or regulatory authority in connection with any such possible violation, in each case as is consistent with applicable law, to the extent such activity is protected under the whistleblower provisions of federal, state or local law, and without any prior notice to or authorization from the General Partner.

SECTION 11.16. Ownership and Use of Names. The Partnership acknowledges that Blackstone TM L.L.C. (“TM”), a Delaware limited liability company with a principal place of business at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, (or its successors or assigns) is the sole and exclusive owner of the mark and name BLACKSTONE and that the ownership of, and the right to use, sell or otherwise dispose of, BLACKSTONE name or any abbreviation or modification thereof which consists of or includes BLACKSTONE, shall belong exclusively to TM, which company (or its predecessors, successors or assigns) has licensed the Partnership to use BLACKSTONE in its name.

(b) The Investment Manager shall (directly or through an Affiliate) maintain a staff trained and experienced in the business of identifying and structuring transactions contemplated by the Partnership Agreement. Services to be rendered by the Investment Manager in connection with the Partnership’s investment program shall include:

(i) analysis and investigation of potential Portfolio Entities, including their products, services, markets, management, financial situation, competitive position, market ranking and prospects for future performance and analyzing other Investments, including primary and secondary investments in funds;

(ii) analysis and investigation of potential dispositions of Investments, including identification of potential acquirers and evaluation of offers made by such potential acquirers;

(iii) structuring of acquisitions of Investments, including through BXINFRA Aggregator (CYM) L.P. and other Intermediate Entities;

(iv) identification of bank and institutional sources of financing, arrangement of appropriate introductions and marketing of financing proposals;

(v) supervision of the preparation and review of all documents required in connection with the acquisition, disposition or financing of each Investment;

(vi) monitoring the performance of Portfolio Entities and, where appropriate, providing advice to the management of the Portfolio Entities at the policy level during the life of an Investment;

(vii) arranging and coordinating the services of other professionals and consultants, including Blackstone; and

(viii) providing the Partnership with such other services as the General Partner may, from time to time, appoint the Investment Manager to be responsible for and perform.

(c) Notwithstanding the services provided by the Investment Manager, the Investment Manager shall not be authorized to manage the affairs of, act in the name of, or bind the Partnership. The management, policies and operations of the Partnership shall be the responsibility of the General Partner acting pursuant to and in accordance with the Partnership Agreement, and all decisions relating to Partnership matters, including, without limitation, the acquisition, management and disposition of Investments, shall be made by the General Partner acting pursuant to and in accordance with the Partnership Agreement.

2

(d) The General Partner, on behalf of the Partnership, shall appoint the Investment Manager to be responsible for and perform all functions as, in the General Partner’s reasonable discretion, constitute: (i) portfolio management and risk management functions in respect of the Partnership, and (ii) such other functions or responsibilities (if any) as the General Partner determines are appropriate to be carried out by the Investment Manager, in each case, in substitution for, and to the exclusion of, the General Partner. The General Partner will monitor the Investment Manager’s performance of such functions. For the avoidance of doubt, the Investment Manager shall be permitted to engage one or more Affiliates to serve as a sub-manager.

3. Management Fee, Other Fees and Administration Fee. (a) Pursuant to Section 6.2 of the Partnership Agreement, the Partnership (directly or indirectly through an Intermediate Entity) shall pay to the Investment Manager a management fee with respect to each Limited Partner (the “Management Fee”), calculated in the manner set forth below.

(b) The Management Fee shall be calculated and paid monthly by BXINFRA (directly or indirectly through an Intermediate Entity) in arrears on the last Business Day of each calendar month and shall be equal to, for each calendar month commencing six calendar months after the Initial Closing Date, in the aggregate, an annualized rate of 1.25% of the net asset value (“NAV”) of BXINFRA. The Management Fee shall be payable by BXINFRA before giving effect to any accruals for the Management Fee, Servicing Fees, the Administration Fee, the Performance Participation Allocation, pending Aggregator Unit repurchases, any distributions and without taking into account accrued and unpaid taxes of any Intermediate Entity through which BXINFRA indirectly invests in an Investment (or any comparable entities of any Other Blackstone Accounts in which BXINFRA directly or indirectly participates) or taxes paid by any such entity during the applicable month. The Partnership, any Feeder Fund and/or Parallel Fund will each be obligated to pay (without duplication) its proportional share of the Management Fee based on its proportional interest in the Aggregator. The Investment Manager may elect to receive the Management Fee in cash, Units of the Partnership and/or any Parallel Fund and/or shares, units or interests (as applicable) of Intermediate Entities (which may, for the avoidance of doubt, be paid or allocated directly by an Intermediate Entity). If the Management Fee is paid in Units, such Units may be repurchased by the Partnership at NAV at the Investment Manager’s request and will be subject to the volume limitations in the Unit Repurchase Program but not the early repurchase deduction of the Unit Repurchase Program.

(c) Any fees (other than the Management Fee, the Servicing Fee and the Administration Fee) earned by the Investment Manager and/or its Affiliates from or with respect to BXINFRA’s investment activities and/or Portfolio Entities and from unconsummated transactions, including, without limitation, net break-up and topping fees, commitment fees, transaction fees, monitoring fees, directors’ fees, investment banking fees, construction, development and other property/asset management fees (including, for example, services relating to the preparation of monthly cash flow models and industry research reports and sourcing, diligence and underwriting and other similar services), mortgage servicing fees, consulting fees (including management consulting), syndication fees, capital markets syndication and advisory fees (including underwriting fees, and with respect to syndications or placements of debt and/or equity securities or instruments issued by Portfolio Entities or entities formed to invest therein), origination fees, servicing (including loan/mortgage/asset servicing) fees, healthcare consulting/brokerage fees, group purchasing fees and/or insurance (including title insurance),

financial advisory fees, organization fees, financing fees, divestment fees and other similar fees, treasury and valuation services, energy procurement / brokerage fees, fees for ESG services, data management and services fees or payments, leasing/administrative fees, similar fees for arranging acquisitions and other financial restructurings, other similar operational and financial matters, (whether in cash or in-kind), other fees and annual retainers (whether in cash or in-kind) and any other fees as further described in the Memorandum as updated from time to time (collectively, “Other Fees”) shall be paid directly to the Investment Manager or its Affiliates and BXINFRA recognizes and consents that the Investment Manager and its Affiliates may receive such Other Fees and the Management Fee shall not be affected thereby except as expressly set forth in the last sentence of this Section 3(c); provided, that such Other Fees and any Reduction Amount (defined below) shall generally be allocated among the Partnership, any Feeder Funds, Parallel Funds and/or Intermediate Entities, Other Blackstone Accounts, or other Persons pro rata as determined in the good faith discretion of the Investment Manager and its affiliates. However, the Management Fee paid by each Limited Partner (indirectly through the Partnership) (in addition to any Management Fee reduction pursuant to Section 4.1(a)(i) of the Partnership Agreement) shall be reduced (but not below zero) by an amount (the “Reduction Amount”) equal to 100% of the Partnership’s pro rata share of the net break-up, topping, commitment, transaction, monitoring, directors’, organization and divestment fees and management and performance fees borne by the Partnership through Secondary Investments in an Other Blackstone Account (excluding Secondary Investments in Other Blackstone Accounts that were made as part of a portfolio transaction) paid to the Investment Manager or its Affiliates in connection with the Partnership’s Investments.

(d) Such Other Fees shall be net of, to the extent not reimbursed or paid as provided herein, reasonable out-of-pocket expenses incurred by the Investment Manager or its Affiliates (and not otherwise reimbursed) in connection with the transaction out of which such fees arose. Subject to the foregoing, the Reduction Amounts in respect of fees received by the Investment Manager and its Affiliates in any month shall be based upon the aggregate of fees received by the Investment Manager and its Affiliates. The Reduction Amounts for each month shall be applied to reduce the Management Fee payable at the beginning of the immediately succeeding month (but not to an amount below zero).

(e) The Investment Manager and its Affiliates may receive fees of the type described in this Section 3 from companies other than BXINFRA’s Portfolio Entities and their Affiliates and those involved in BXINFRA’s unconsummated transactions, including in connection with a joint venture in which BXINFRA participates or otherwise with respect to assets or other interests retained by a seller or other commercial counterparty of BXINFRA and/or as otherwise described in the Memorandum. The Investment Manager and its Affiliates shall have no obligation to reduce the Management Fee in respect of such fees or share such fees in any way with BXINFRA or the Limited Partners.

(f) The Management Fee for each of (i) the first calendar month after the first six months following the Initial Closing Date and (ii) the last calendar month of BXINFRA shall each be prorated for the number of days in such period.

(g) Administration Fee. Pursuant to Section 6.2 of the Partnership Agreement, the Partnership (directly or indirectly through an Intermediate Entity) shall pay to the Investment Manager an administration fee (the “Administration Fee”). The Administration Fee shall be payable in cash monthly in arrears on the last Business Day of each calendar month and shall be equal to, in the aggregate, an annualized rate of 0.10% of the NAV of BXINFRA. The Administration Fee shall be payable by BXINFRA before giving effect to any accruals for the Management Fee, the Servicing Fee, the Administration Fee, the Performance Participation Allocation, pending Aggregator Unit repurchases, any distributions and without taking into account accrued and unpaid taxes of an Intermediate Entity (including corporations) through which BXINFRA indirectly invests in an Investment (or any comparable entities of any Other Blackstone Accounts in which BXINFRA directly or indirectly participates) or taxes paid by any such entity during the applicable month. The Partnership, any Feeder Fund and any Parallel Fund will each be obligated to pay (without duplication) its proportional share of the Administration Fee based on its proportional interest in the Aggregator. The Administration Fee will be separate from and additional to the Management Fee and any Fund Expenses (including administrative expenses incurred in connection with Investments and Portfolio Entities). From time to time, the Investment Manager may outsource certain administrative duties provided to BXINFRA with respect to the Administration Fee to third-parties. The fees, costs and expenses of any such third-party service providers will be payable by the Investment Manager out of its Administration Fee.

4. Organizational and Offering Expenses. The Investment Manager hereby agrees to advance all of BXINFRA’s organizational and offering expenses on BXINFRA’s behalf (including legal, accounting, printing, mailing, subscription processing and filing fees and expenses, due diligence expenses of participating placement agents or financial intermediaries supported by detailed and itemized invoices, costs in connection with preparing sales materials, design and website expenses, fees and expenses of each entity (including, as applicable, transfer agent, administrator and depository fees, fees to attend retail seminars sponsored by participating broker-dealers and reimbursements for customary travel, lodging, entertainment and meals and including all similar organizational and offering expenses of any Feeder Funds, Parallel Funds and/or Intermediate Entities primarily organized to invest in BXINFRA to the extent not paid by such Feeder Funds, Parallel Funds and/or Intermediate Entities or their investors, but excluding subscription fees and Servicing Fees)) (collectively, “Organizational and Offering Expenses”) through the first anniversary of the Initial Closing Date. On the Initial Closing Date (i.e., the day on which BXINFRA first accepts third-party investors and begins investment operations), BXINFRA will be obligated to reimburse the Investment Manager for all such advanced Organizational and Offering Expenses ratably over the 60 months following the first anniversary of the Initial Closing Date. The Investment Manager will determine what Organizational and Offering Expenses are attributable to the Partnership or any Feeder Fund, Parallel Fund or Intermediate Entity, in its sole discretion.

5. Initial Fund Expenses Support. The Investment Manager may, in its discretion, advance all or a portion of the Fund Expenses to be borne by BXINFRA and the appropriately apportioned expenses relating to the Portfolio Entities, Feeder Funds, Parallel Funds and/or Intermediate Entities to the extent not paid by such Portfolio Entities, Feeder Funds, Parallel Funds and/or Intermediate Entities, in each case as determined pursuant to the terms of this Agreement and the Partnership Agreement (collectively, “Initial Fund Expenses Support”) through the first anniversary of the Initial Closing Date. BXINFRA will reimburse the Investment Manager for all such advanced expenses ratably over the 60 months following the first anniversary of the Initial Closing Date or on such earlier date as determined by the Investment Manager. The Investment Manager will determine the portion of Initial Fund Expenses Support that is attributable to the Partnership or any Portfolio Entity, Feeder Fund, Parallel Fund and/or Intermediate Entity in its sole discretion.

6. Exculpation and Indemnification.

7. Term. The term of this Agreement shall be the same as the term of the Partnership Agreement as set forth in Section 9.1 thereof. This Agreement shall be terminated upon the earliest to occur of (a) the decision of the Partnership in the sole discretion of the General Partner upon sixty (60) days’ notice to so terminate, (b) the bankruptcy of the Investment Manager, and (c) the termination of the Partnership.

8. Miscellaneous. (a) This Agreement may be amended, modified or supplemented at any time and from time to time by an instrument in writing signed by each party hereto, or their respective successors or assigns (including, without limitation, amendments to conform to successor entities and applicable regulatory requirements), or otherwise as provided herein, and any provision herein may be waived, by the written consent of the General Partner; provided that any amendment, modification or supplement that, in the General Partner’s discretion, viewed as a whole together with all such amendments, modifications or supplements, would have a material adverse effect on the Limited Partners in the aggregate will require the prior approval of the Independent Directors.

(b) Any notice shall be deemed to have been duly given if (i) personally delivered, when received, (ii) sent by United States Express Mail or recognized overnight courier on the second following Business Day (or third following Business Day if mailed outside the United States), (iii) delivered by electronic mail, when received, or (iv) posted on a password protected website maintained by the Partnership or its Affiliates and for which any Limited Partner has received access instructions by electronic mail, when posted.

All such counterparts shall constitute one and the same document. For the avoidance of doubt, any party’s execution and delivery of this Agreement (or any agreement, document or notice required or permitted by this Agreement, or any amendment to this Agreement) by electronic signature and/or electronic transmission shall constitute the execution and delivery of a counterpart of the executed document by or on behalf of such party and shall bind such party to its terms. The authorization under this paragraph may include, without limitation, a manually signed paper document which has been converted into electronic form (such as scanned into PDF format or transmitted via facsimile), or an electronically signed document converted into another format, for transmission, delivery and/or retention.

(e) This Agreement is intended to create, and creates, a contractual relationship for services to be rendered by the Investment Manager acting in the ordinary course of its business as an independent contractor and is not intended to create, and does not create, a partnership, joint venture or any like relationship among the parties hereto (or any other parties). The provisions of this Agreement shall be construed in accordance with and governed by the laws of the State of New York.

(f) Without the consent of a majority of the Independent Directors (which, for the avoidance of doubt, would include all of the Independent Directors in the event there were two or fewer Independent Directors on the Board of Directors), the Investment Manager shall not assign, sell or otherwise dispose of all or any part of its right, title and interest in and to this Agreement, except to an Affiliate thereof; provided, that nothing in this Agreement shall preclude changes in the composition of the members constituting the limited liability company which is the Investment Manager so long as Blackstone and its Affiliates control such limited liability company; provided, further, that such limited liability company may be reconstituted from the limited liability company form to the limited partnership form, the general partnership form or to the corporate form or vice versa or any other form of entity so long as Blackstone and its Affiliates control such reconstituted entity.

(g) No failure on the part of either party to exercise, and no delay on its part in exercising, any right or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right or remedy under this Agreement preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided in this Agreement are cumulative and not exclusive of any rights or remedies provided by law.
