The General Partner shall have the authority to enter into separate agreements with any Covered Person in order to give effect to the obligations to indemnify pursuant to this Section 3.5(b).

(ii) (A) Notwithstanding anything to the contrary herein, for greater certainty, it is understood and/or agreed that the Partnership’s obligations hereunder are not intended to render the Partnership as a primary indemnitor for purposes of the indemnification, advancement of expenses and related provisions under applicable law governing SP Infrastructure III and/or a particular portfolio entity through which an Investment is indirectly held. It is further understood and/or agreed that a Covered Person shall first seek to be so indemnified and have such expenses advanced in the following order of priority: first, out of proceeds available in respect of applicable insurance policies maintained by the applicable portfolio entity and/or SP Infrastructure III; second, by the applicable portfolio entity through which such investment is indirectly held; and third, by SP Infrastructure III (only to the extent the foregoing sources are exhausted).

(B) The Partnership’s obligation, if any, to indemnify or advance expenses to any Covered Person shall be reduced by any amount that such Covered Person may collect as indemnification or advancement from SP Infrastructure III and/or the applicable portfolio entity (including by virtue of any applicable insurance policies maintained thereby), and to the extent the Partnership (or any Affiliate thereof) pays or causes to be paid any amounts that should have been paid by SP Infrastructure III and/or the applicable portfolio entity (including by virtue of any applicable insurance policies maintained thereby), it is agreed among the Partners that the Partnership shall have a subrogation claim against SP Infrastructure III and/or such portfolio 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 (except for a loan to an executive officer of The Blackstone Group Inc. or any of its Affiliates, which shall not be permitted) as the General Partner may determine necessary or advisable to give effect to or otherwise implement the foregoing.

Section 3.6. Representations of Partners.

(a) Each Limited Partner and Special Partner by execution of this Agreement (or by otherwise becoming bound by the terms and conditions hereof as provided herein or in the Partnership Act) represents and warrants to every other Partner and to the Partnership, except as may be waived by the General Partner, that such Partner is acquiring each of such Partner’s Interests for such Partner’s own account for investment and not with a view to resell or distribute the same or any part hereof, and that no other person has any interest in any such Interest or in the rights of such Partner hereunder; provided, that a Partner may choose to make transfers for estate and charitable planning purposes (pursuant to Section 6.3(a) and otherwise in accordance with the terms hereof). Each Limited Partner and Special Partner represents and warrants that such Partner understands that the Interests have not been registered under the Securities Act, and therefore such Interests may not be resold without registration under the Securities Act or exemption from such registration, and that accordingly such Partner must bear the economic risk of an investment in the Partnership for an indefinite period of time. Each Limited Partner and Special Partner represents that such Partner has such knowledge and experience in financial and business matters that such Partner is capable of evaluating the merits and risks of an investment in the Partnership, and that such Partner is able to bear the economic risk of such investment. Each Limited Partner and Special Partner represents that such Partner’s overall commitment to the Partnership and other investments which are not readily marketable is not disproportionate to the Partner’s net worth and the Partner has no need for liquidity in the Partner’s investment in Interests. Each Limited Partner and Special Partner represents that to the full satisfaction of the Partner, the Partner has been furnished any materials that such Partner has requested relating to the Partnership, any Investment and the offering of Interests and has been afforded the opportunity to ask questions of representatives of the Partnership concerning the terms and conditions of the offering of Interests and any matters pertaining to each Investment and to obtain any other additional information relating thereto. Each Limited Partner and Special Partner represents that the Partner has consulted to the extent deemed appropriate by the Partner with the Partner’s own advisers as to the financial, tax, legal and related matters concerning an investment in Interests and on that basis believes that an investment in the Interests is suitable and appropriate for the Partner.

(b) Each Limited Partner and Special Partner agrees that the representations and warranties contained in paragraph (a) above shall be true and correct as of any date that such Partner (1) makes a capital contribution to the Partnership (whether as a result of Firm Advances made to such Partner or otherwise) with respect to any Investment, and such Partner hereby agrees that such capital contribution shall serve as confirmation thereof and/or (2) repays any portion of the principal amount of a Firm Advance, and such Partner hereby agrees that such repayment shall serve as confirmation thereof.

Section 3.7. Tax Representation and Further Assurances. (a) Each Limited Partner and Special Partner, upon the request of the General Partner, agrees to perform all further acts and to execute, acknowledge and deliver any documents that may be reasonably necessary to comply with the General Partner’s or the Partnership’s obligations under applicable law or to carry out the provisions of this Agreement.

(b) Each Limited Partner and Special Partner certifies that (A) if the Limited Partner or Special Partner is a United States person (as defined in the Code) (x) (i) the Limited Partner or Special Partner’s name, social security number (or, if applicable, employer identification number) and address provided to the Partnership and its Affiliates pursuant to an IRS Form W 9, Request for Taxpayer Identification Number Certification (“W 9”) or otherwise are correct and (ii) the Limited Partner or Special Partner will complete and return a W 9 and (y) (i) the Limited Partner or Special Partner is a United States person (as defined in the Code) and (ii) the Limited Partner or Special Partner will notify the Partnership within 60 days of a change to foreign (non-United States) status or (B) if the Limited Partner or Special Partner is not a United States person (as defined in the Code) (x) (i) the information on the completed IRS Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals) (“W-8BEN”), IRS Form W-8BEN-E, Certificate of Status of Beneficial Owner for United States Tax Withholding and Reporting (Entities) (“W-8BEN-E”), or other applicable form, including but not limited to IRS Form W-8IMY, Certificate of Foreign Intermediary, Foreign Flow-Through Entity, or Certain U.S. Branches for United States Tax Withholding and Reporting (“W-8IMY”), or otherwise is correct and (ii) the Limited Partner or Special Partner will complete and return the applicable IRS form, including but not limited to a W-8BEN, W-8BEN-E or W-8IMY, and (y) (i) the Limited Partner or Special Partner is not a United States person (as defined in the Code) and (ii) the Limited Partner or Special Partner will notify the Partnership within 60 days of any change of such status. Each Limited Partner and Special Partner agrees to provide such cooperation and assistance, including but not limited to properly executing and providing to the Partnership in a timely manner any tax or other documentation or information that may be reasonably requested by the Partnership or the General Partner.

(c) Each Limited Partner and Special Partner acknowledges and agrees that the Partnership and the General Partner may release confidential information or other information about the Limited Partner or Special Partner or related to such Limited Partner or Special Partner’s investment in the Partnership if the Partnership or the General Partner, in its or their sole discretion, determines that such disclosure is required by applicable law or regulation or in order to comply for an exception from, or reduced tax rate of, tax or other tax benefit. Any such disclosure shall not be treated as a breach of any restriction upon the disclosure of information imposed on any such person by law or otherwise, and a Limited Partner or Special Partner shall have no claim against the Partnership, the General Partner or any of their Affiliates for any form of damages or liability as a result of actions taken by the foregoing in order to comply with any disclosure obligations that the foregoing reasonably believe are required by law, regulation or otherwise.

(d) Each Limited Partner and Special Partner acknowledges and agrees that if it provides information that is in anyway materially misleading, or if it fails to provide the Partnership or its agents with any information requested hereunder, in either case in order to satisfy the Partnership’s obligations, the General Partner reserves the right to take any action and pursue any remedies at its disposal, including (i) requiring such Limited Partner or Special Partner to Withdraw for Cause and (ii) withholding or deducting any costs caused by such Limited Partner’s or Special Partner’s action or inaction from amounts otherwise distributable to such Limited Partner or Special Partner from the Partnership and its Affiliates.

ARTICLE IV

CAPITAL OF THE PARTNERSHIP

Section 4.1. Capital Contributions by Partners. (a) Each Partner shall be required to make capital contributions to the Partnership (“GP-Related Capital Contributions”) at such times and in such amounts (the “GP-Related Required Amounts”) as are required to satisfy the Partnership’s obligation to make capital contributions to SP Infrastructure III in respect of the GP-Related SP Infrastructure III Interest with respect to any GP-Related SP Infrastructure III Investment and as are otherwise determined by the General Partner from time to time or as may be set forth in such Limited Partner’s Commitment Agreement or SMD Agreement, if any, or otherwise; provided, that additional GP-Related Capital Contributions in excess of the GP-Related Required Amounts may be made pro rata among the Partners based upon each Partner’s Carried Interest Sharing Percentage. GP-Related Capital Contributions in excess of the GP-Related Required Amounts which are to be used for ongoing business operations (as distinct from financing, legal or other specific liabilities of the Partnership (including those specifically set forth in Section 4.1(d) and Section 5.8(d))) shall be determined by the General Partner. Special Partners shall not be required to make additional GP-Related Capital Contributions to the Partnership in excess of the GP-Related Required Amounts, except (i) as a condition of an increase in such Special Partner’s GP-Related Profit Sharing Percentage or (ii) as specifically set forth in this Agreement; provided, that the General Partner and any Special Partner may agree from time to time that such Special Partner shall make an additional GP-Related Capital Contribution to the Partnership; provided, further, that each Investor Special Partner shall maintain its GP-Related Capital Accounts at an aggregate level equal to the product of (i) its GP-Related Profit Sharing Percentage from time to time and (ii) the total capital of the Partnership related to the GP-Related SP Infrastructure III Interest.

(b) Each GP-Related Capital Contribution by a Partner shall be credited to the appropriate GP-Related Capital Account of such Partner in accordance with Section 5.2, subject to Section 5.10.

(c) The General Partner may elect on a case by case basis to (i) cause the Partnership to loan any Partner (including any additional Partner admitted to the Partnership pursuant to Section 6.1 but excluding any Partners who are also executive officers of The Blackstone Group Inc. or any Affiliate thereof) the amount of any GP-Related Capital Contribution required to be made by such Partner or (ii) permit any Partner (including any additional Partner admitted to the Partnership pursuant to Section 6.1 but excluding any Partners who are also executive officers of The Blackstone Group Inc. or any Affiliate thereof) to make a required GP-Related Capital Contribution to the Partnership in installments, in each case on terms determined by the General Partner.

(d) (i) The Partners and the Withdrawn Partners have entered into the Trust Agreement, pursuant to which certain amounts of the distributions relating to Carried Interest will be paid to the Trustee(s) for deposit in the Trust Account (such amounts to be paid to the Trustee(s) for deposit in the Trust Account constituting a “Holdback”). The General Partner shall determine, as set forth below, the percentage of each distribution of Carried Interest that shall be withheld for any General Partner and/or Holdings and each Partner Category (such withheld percentage constituting the General Partner’s and such Partner Category’s “Holdback Percentage”). The applicable Holdback Percentages initially shall be 0% for any General Partner, 15% for Existing Partners (other than the General Partner), 21% for Retaining Withdrawn Partners (other than the General Partner) and 24% for Deceased Partners (the “Initial Holdback Percentages”). Any provision of this Agreement to the contrary notwithstanding, the Holdback Percentage for the General Partner and/or Holdings shall not be subject to change pursuant to clause (ii), (iii) or (iv) of this Section 4.1(d).

(ii) The Holdback Percentage may not be reduced for any individual Partner as compared to the other Partners in his or her Partner Category (except as provided in clause (iv) below). The General Partner may only reduce the Holdback Percentages among the Partner Categories on a proportionate basis. For example, if the Holdback Percentage for Existing Partners is decreased to 12.5%, the Holdback Percentage for Retaining Withdrawn Partners and Deceased Partners shall be reduced to 17.5% and 20%, respectively. Any reduction in the Holdback Percentage for any Partner shall apply only to distributions relating to Carried Interest made after the date of such reduction.

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

(iv) (A) Notwithstanding anything contained herein to the contrary, the General Partner may increase or decrease the Holdback Percentage for any Partner in any Partner Category (in such capacity, the “Subject Partner”) pursuant to a majority vote of the Limited Partners (a “Holdback Vote”); provided, that, notwithstanding anything to the contrary contained herein, the Holdback Percentage applicable to any General Partner shall not be increased or decreased without its prior written consent; provided further, that a Subject Partner’s Holdback Percentage shall not be (I) increased prior to such time as such Subject Partner (x) is notified by the Partnership of the decision to increase such Subject Partner’s Holdback Percentage and (y) has, if requested by such Subject Partner, been given 30 days to gather and provide information to the Partnership for consideration before a second Holdback Vote (requested by the Subject Partner) or (II) decreased unless such decrease occurs subsequent to an increase in a Subject Partner’s Holdback Percentage pursuant to a Holdback Vote under this clause (iv); provided further, that such decrease shall not exceed an amount such that such Subject Partner’s Holdback Percentage is less than the prevailing Holdback Percentage for the Partner Category of such Subject Partner; provided further, that a Partner shall not vote to increase a Subject Partner’s Holdback Percentage unless such voting Partner determines, in such Partner’s good faith judgment, that the facts and circumstances indicate that it is reasonably likely that such Subject Partner, or any of such Subject Partner’s successors or assigns (including such Subject Partner’s estate or heirs) who at the time of such vote holds the GP-Related Partner Interest or otherwise has the right to receive distributions relating thereto, will not be capable of satisfying any GP-Related Recontribution Amounts that may become due.

(B) A Holdback Vote shall take place at a Partnership meeting. Each of the Limited Partners shall be entitled to cast one vote with respect to the Holdback Vote regardless of such Limited Partner’s interest in the Partnership. Such vote may be cast by any such Partner in person or by proxy.

(C) If the result of the second Holdback Vote is an increase in a Subject Partner’s Holdback Percentage, such Subject Partner may submit the decision to an arbitrator, the identity of which is mutually agreed upon by both the Subject Partner and the Partnership; provided, that if the Partnership and the Subject Partner cannot agree upon a mutually satisfactory arbitrator within 10 days of the second Holdback Vote, each of the Partnership and the Subject Partner shall request its candidate for arbitrator to select a third arbitrator satisfactory to such candidates; provided further, that if such candidates fail to agree upon a mutually satisfactory arbitrator within 30 days of such request, the then sitting President of the American Arbitration Association shall unilaterally select the arbitrator. Each Subject Partner that submits the decision of the Partnership pursuant to the second Holdback Vote to arbitration and the Partnership shall estimate their reasonably projected out-of-pocket expenses relating thereto, and each such party shall, to the satisfaction of the arbitrator and prior to any determination being made by the arbitrator, pay the total of such estimated

expenses (i.e., both the Subject Partner’s and the Partnership’s expenses) into an escrow account. The arbitrator shall direct the escrow agent to pay out of such escrow account all expenses associated with such arbitration (including costs leading thereto) and to return to the “victorious” party the entire amount of funds such party paid into such escrow account. If the amount contributed to the escrow account by the losing party is insufficient to cover the expenses of such arbitration, such “losing” party shall then provide any additional funds necessary to cover such costs to such “victorious” party. For purposes hereof, the “victorious” party shall be the Partnership if the Holdback Percentage ultimately determined by the arbitrator is closer to the percentage determined in the second Holdback Vote than it is to the prevailing Holdback Percentage for the Subject Partner’s Partner Category; otherwise, the Subject Partner shall be the “victorious” party. The party that is not the “victorious” party shall be the “losing” party.

(D) In the event of a decrease in a Subject Partner’s Holdback Percentage (1) pursuant to a Holdback Vote under this clause (iv) or (2) pursuant to a decision of an arbitrator under paragraph (C) of this clause (iv), the Partnership shall release and distribute to such Subject Partner any Trust Amounts (and the Trust Income thereon (except as expressly provided herein with respect to using Trust Income as Firm Collateral)) which exceed the required Holdback of such Subject Partner (in accordance with such Subject Partner’s reduced Holdback Percentage) as though such reduced Holdback Percentage had applied since the increase of the Subject Partner’s Holdback Percentage pursuant to a previous Holdback Vote under this clause (iv).

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

unavailable because of an existing lien on such Firm Collateral, the Partner or Withdrawn Partner seeking to utilize such Firm Collateral shall grant the General Partner a second priority security interest therein in the manner provided above; provided further, that (x) in the case of Pledgable Blackstone Interests, to the extent that neither a first priority nor a second priority security interest is available, or (y) if the General Partner otherwise determines in its good faith judgment that a security interest in Firm Collateral (and the corresponding documents and actions) are not necessary or appropriate, the Partner or Withdrawn Partner shall (in the case of either clause (x) or (y) above) irrevocably instruct in writing the relevant partnership, limited liability company or other entity listed in the Partnership’s books and records to remit any and all net proceeds resulting from a Firm Collateral Realization on such Firm Collateral to the Trustee(s) as more fully provided in clause (B) below. The Partnership shall, at the request of any Partner or Withdrawn Partner, assist such Partner or Withdrawn Partner in taking such action as is necessary to enable such Partner or Withdrawn Partner to use Firm Collateral as provided hereunder.

(B) If upon a sale or other realization of all or any portion of any Firm Collateral (a “Firm Collateral Realization”), the remaining Firm Collateral is insufficient to cover any Partner’s or Withdrawn Partner’s Excess Holdback requirement, then up to 100% of the net proceeds otherwise distributable to such Partner or Withdrawn Partner from such Firm Collateral Realization (including distributions subject to the repayment of financing sources as in the case of Pledgable Blackstone Interests) shall be paid into the Trust Account to fully satisfy such Excess Holdback requirement (allocated to such Partner or Withdrawn Partner) and shall be deemed to be Trust Amounts for purposes hereunder. Any net proceeds from such Firm Collateral Realization in excess of the amount necessary to satisfy such Excess Holdback requirement shall be distributed to such Partner or Withdrawn Partner.

(C) Upon any valuation or revaluation of Firm Collateral that results in a decreased valuation of such Firm Collateral so that such Firm Collateral is insufficient to cover any Partner’s or Withdrawn Partner’s Excess Holdback requirement (including upon a Firm Collateral Realization, if net proceeds therefrom and the remaining Firm Collateral are insufficient to cover any Partner’s or Withdrawn Partner’s Excess Holdback requirement), the Partnership shall provide notice of the foregoing to such Partner or Withdrawn Partner and such Partner or Withdrawn Partner shall, within 30 days of receiving such notice, contribute cash (or additional Firm Collateral) to the Trust Account in an amount necessary to satisfy his or her Excess Holdback requirement. If any such Partner or Withdrawn Partner defaults upon his or her obligations under this clause (C), then Section 5.8(d)(ii) shall apply thereto; provided, that clause (A) of Section 5.8(d)(ii) shall be deemed inapplicable to a default under this clause (C); provided further, that for purposes of applying Section 5.8(d)(ii) to a default under this clause (C): (I) the term “GP-Related Defaulting Party” where such term appears in such Section 5.8(d)(ii) shall be construed as “defaulting party” for purposes hereof and (II) the terms “Net GP-Related Recontribution Amount” and “GP-Related Recontribution Amount” where such terms appear in such Section 5.8(d)(ii) shall be construed as the amount due pursuant to this clause (C).

(vi) Any Partner or Withdrawn Partner may (A) obtain the release of any Trust Amounts (but not the Trust Income thereon which shall remain in the Trust Account and allocated to such Partner or Withdrawn Partner) or Firm Collateral, in each case, held in the Trust Account for the benefit of such Partner or Withdrawn Partner or (B) require the Partnership to distribute all or any portion of amounts otherwise required to be placed in the Trust Account (whether cash or Firm Collateral), by obtaining a letter of credit (an “L/C”) for the benefit of the Trustee(s) in such amounts. Any Partner or Withdrawn Partner choosing to furnish an L/C to the Trustee(s) (in such capacity, an “L/C Partner”) shall deliver to the Trustee(s) an unconditional and irrevocable L/C from a commercial bank whose (x) short-term deposits are rated at least A-1 by S&P or P-1 by Xxxxx’x (if the L/C is for a term of 1 year or less), or (y) long-term deposits are rated at least A+ by S&P or A1 by Xxxxx’x (if the L/C is for a term of 1 year or more) (each a “Required Rating”). If the relevant rating of the commercial bank issuing such L/C drops below the relevant Required Rating, the L/C Partner shall supply to the Trustee(s), within 30 days of such occurrence, a new L/C from a commercial bank whose relevant rating is at least equal to the relevant Required Rating, in lieu of the insufficient L/C. In addition, if the L/C has a term expiring on a date earlier than the latest possible termination date of SP Infrastructure III, the Trustee(s) shall be permitted to drawdown on such L/C if the L/C Partner fails to provide a new L/C from a commercial bank whose relevant rating is at least equal to the relevant Required Rating, at least 30 days prior to the stated expiration date of such existing L/C. The Trustee(s) shall notify an L/C Partner 10 days prior to drawing on any L/C. The Trustee(s) may (as directed by the Partnership in the case of clause (I) below) draw down on an L/C only if (I) such a drawdown is necessary to satisfy an L/C Partner’s obligation relating to the Partnership’s obligations under the Clawback Provisions or (II) an L/C Partner has not provided a new L/C from a commercial bank whose relevant rating is at least equal to the relevant Required Rating (or the requisite amount of cash and/or Firm Collateral (to the extent permitted hereunder)), at least 30 days prior to the stated expiration of an existing L/C in accordance with this clause (vi). The Trustee(s), as directed by the Partnership, shall return to any L/C Partner his or her L/C upon (1) the termination of the Trust Account and satisfaction of the Partnership’s obligations, if any, in respect of the Clawback Provisions, (2) an L/C Partner satisfying his or her entire Holdback obligation in cash and Firm Collateral (to the extent permitted hereunder), or (3) the release, by the Trustee(s), as directed by the Partnership, of all amounts in the Trust Account to the Partners or Withdrawn Partners. If an L/C Partner satisfies a portion of his or her Holdback obligation in cash and/or Firm Collateral (to the extent permitted hereunder) or if the Trustee(s), as directed by the Partnership, release a portion of the amounts in the Trust Account to the Partners or Withdrawn Partners in the Partner Category of such L/C Partner, the L/C of an L/C Partner may be reduced by an amount corresponding to such portion satisfied in cash and/or Firm Collateral (to the extent permitted hereunder) or such portion released by the Trustee(s), as directed by the Partnership; provided, that in no way shall the general release of any Trust Income cause an L/C Partner to be permitted to reduce the amount of an L/C by any amount.

(vii) (A) Any in-kind distributions by the Partnership relating to Carried Interest shall be made in accordance herewith as though such distributions consisted of cash. The Partnership may direct the Trustee(s) to dispose of any in-kind distributions held in the Trust Account at any time. The net proceeds therefrom shall be treated as though initially contributed to the Trust Account.

(B) In lieu of the foregoing, any Existing Partner may pledge or grant a security interest with respect to any in-kind distribution the Special Firm Collateral referred to in the applicable category in the Partnership’s books and records; provided, that the initial contribution of such Special Firm Collateral shall initially equal 130% of the required Holdback for a period of 90 days, and thereafter shall equal at least 115% of the required Holdback. Sections 4.1(d)(viii)(C) and (D) shall apply to such Special Firm Collateral. To the extent such Special Firm Collateral exceeds the applicable minimum percentage of the required Holdback specified in the first sentence of this clause (vii)(B), the related Partner may obtain a release of such excess amount from the Trust Account.

(viii) (A) Any Limited Partner or Withdrawn Partner may satisfy all or any portion of his or her Holdback (excluding any Excess Holdback), and such Partner or a Withdrawn Partner may, to the extent his or her Holdback (excluding any Excess Holdback) has been previously satisfied in cash or by the use of an L/C as provided herein, obtain a release of Trust Amounts (but not the Trust Income thereon which shall remain in the Trust Account and allocated to such Partner or Withdrawn Partner) that satisfy such Partner’s or Withdrawn Partner’s Holdback (excluding any Excess Holdback) by pledging or otherwise granting a security interest to the Trustee(s) on a first priority basis all of his or her Special Firm Collateral in a particular Qualifying Fund, which at all times must equal or exceed the amount of the Holdback distributed to the Partner or Withdrawn Partner (as more fully set forth below). Any Partner seeking to satisfy such Partner’s Holdback utilizing Special Firm Collateral shall sign such documents and otherwise take such other action as is necessary or appropriate (in the good faith judgment of the General Partner) to perfect a first priority security interest in, and otherwise assure the ability of the Trustee(s) to realize on (if required), such Special Firm Collateral.

(B) If upon a distribution, withdrawal, sale, liquidation or other realization of all or any portion of any Special Firm Collateral (a “Special Firm Collateral Realization”), the remaining Special Firm Collateral (which shall not include the amount of Firm Collateral that consists of a Qualifying Fund and is being used in connection with an Excess Holdback) is insufficient to cover any Partner’s or Withdrawn Partner’s Holdback (when taken together with other means of satisfying the Holdback as provided herein (i.e., cash contributed to the Trust Account or an L/C in the Trust Account)), then up to 100% of the net proceeds otherwise distributable to such Partner or Withdrawn Partner from such Special Firm Collateral Realization (which shall not include the amount of Firm Collateral that consists of a Qualifying Fund or other asset and is being used in connection with an Excess Holdback) shall be paid into the Trust (and allocated to such Partner or Withdrawn Partner) to fully satisfy such Holdback and shall be deemed thereafter to be Trust Amounts for purposes hereunder. Any net proceeds from such Special Firm Collateral Realization in excess of the amount necessary to satisfy such Holdback (excluding any Excess Holdback) shall be distributed to such Partner or Withdrawn Partner. To the extent a Qualifying Fund distributes Securities to a Partner or Withdrawn Partner in connection with a Special Firm Collateral Realization, such Partner or Withdrawn Partner shall be required to promptly fund such Partner’s or Withdrawn Partner’s deficiency with respect to his or her Holdback in cash or an L/C.

(C) Upon any valuation or revaluation of the Special Firm Collateral and/or any adjustment in the Applicable Collateral Percentage applicable to a Qualifying Fund (as provided in the Partnership’s books and records), if such Partner’s or Withdrawn Partner’s Special Firm Collateral is valued at less than such Partner’s Holdback (excluding any Excess Holdback) as provided in the Partnership’s books and records, taking into account other permitted means of satisfying the Holdback hereunder, the Partnership shall provide notice of the foregoing to such Partner or Withdrawn Partner and, within 10 Business Days of receiving such notice, such Partner or Withdrawn Partner shall contribute cash or additional Special Firm Collateral to the Trust Account in an amount necessary to make up such deficiency. If any such Partner or Withdrawn Partner defaults upon his or her obligations under this clause (C), then Section 5.8(d)(ii) shall apply thereto; provided, that the first sentence of Section 5.8(d)(ii)(A) shall be deemed inapplicable to such default; provided further, that for purposes of applying Section 5.8(d)(ii) to a default under this clause (C): (I) the term “GP-Related Defaulting Party” where such term appears in such Section 5.8(d)(ii) shall be construed as “defaulting party” for purposes hereof and (II) the terms “Net GP-Related Recontribution Amount” and “GP-Related Recontribution Amount” where such terms appear in such Section 5.8(d)(ii) shall be construed as the amount due pursuant to this clause (C).

(D) Upon a Partner becoming a Withdrawn Partner, at any time thereafter the General Partner may revoke the ability of such Withdrawn Partner to use Special Firm Collateral as set forth in this Section 4.1(d)(viii), notwithstanding anything else in this Section 4.1(d)(viii). In that case the provisions of clause (C) above shall apply to the Withdrawn Partner’s obligation to satisfy the Holdback (except that 30 days’ notice of such revocation shall be given), given that the Special Firm Collateral is no longer available to satisfy any portion of the Holdback (excluding any Excess Holdback).

(E) Nothing in this Section 4.1(d)(viii) shall prevent any Partner or Withdrawn Partner from using any amount of such Partner’s interest in a Qualifying Fund as Firm Collateral; provided, that at all times Section 4.1(d)(v) and this Section 4.1(d)(viii) are each satisfied.

Section 4.2. Interest. Interest on the balances of the Partners’ capital related to the Partners’ GP-Related Partner Interests (excluding capital invested in GP-Related Investments and, if deemed appropriate by the General Partner, capital invested in any other investment of the Partnership) shall be credited to the Partners’ GP-Related Capital Accounts at the end of each accounting period pursuant to Section 5.2, or at any other time as determined by the General Partner, at rates determined by the General Partner from time to time, and shall be charged as an expense of the Partnership.

Section 4.3. Withdrawals of Capital. No Partner may withdraw capital related to such Partner’s GP-Related Partner Interests from the Partnership except (i) for distributions of cash or other property pursuant to Section 5.8, (ii) as otherwise expressly provided in this Agreement or (iii) as determined by the General Partner.

ARTICLE V

PARTICIPATION IN PROFITS AND LOSSES

Section 5.1. General Accounting Matters.

(a) GP-Related Net Income (Loss) shall be determined by the General Partner at the end of each accounting period and shall be allocated as described in Section 5.4.

(b) “GP-Related Net Income (Loss)” means:

(i) from any activity of the Partnership related to the GP-Related SP Infrastructure III Interest for any accounting period (other than GP-Related Net Income (Loss) from GP-Related Investments described below), (x) the gross income realized by the Partnership from such activity during such accounting period less (y) all expenses of the Partnership, and all other items that are deductible from gross income, for such accounting period that are allocable to such activity (determined as provided below);

(ii) from any GP-Related Investment for any accounting period in which such GP-Related Investment has not been sold or otherwise disposed of, (x) the gross amount of dividends, interest or other income received by the Partnership from such GP-Related Investment during such accounting period less (y) all expenses of the Partnership for such accounting period that are allocable to such GP-Related Investment (determined as provided below); and

(iii) from any GP-Related Investment for the accounting period in which such GP-Related Investment is sold or otherwise disposed of, (x) the sum of the gross proceeds from the sale or other disposition of such GP-Related Investment and the gross amount of dividends, interest or other income received by the Partnership from such GP-Related Investment during such accounting period less (y) the sum of the cost or other basis to the Partnership of such GP-Related Investment and all expenses of the Partnership for such accounting period that are allocable to such GP-Related Investment.

(c) GP-Related Net Income (Loss) shall be determined in accordance with the accounting method used by the Partnership for U.S. federal income tax purposes with the following adjustments: (i) any income of the Partnership that is exempt from U.S. federal income taxation and not otherwise taken into account in computing GP-Related Net Income (Loss) shall be added to such taxable income or loss; (ii) if any asset has a value in the books of the Partnership that differs from its adjusted tax basis for U.S. federal income tax purposes, any depreciation, amortization or gain resulting from a disposition of such asset shall be calculated

with reference to such value; (iii) upon an adjustment to the value of any asset in the books of the Partnership pursuant to Treasury Regulations Section 1.704-1(b)(2), the amount of the adjustment shall be included as gain or loss in computing such taxable income or loss; (iv) any expenditures of the Partnership not deductible in computing taxable income or loss, not properly capitalizable and not otherwise taken into account in computing GP-Related Net Income (Loss) pursuant to this definition shall be treated as deductible items; (v) any income from a GP-Related Investment that is payable to Partnership employees in respect of “phantom interests” in such GP-Related Investment awarded by the General Partner to employees shall be included as an expense in the calculation of GP-Related Net Income (Loss) from such GP-Related Investment, and (vi) items of income and expense (including interest income and overhead and other indirect expenses) of the Partnership, Holdings and other Affiliates of the Partnership shall be allocated among the Partnership, Holdings and such Affiliates, among various Partnership activities and GP-Related Investments and between accounting periods, in each case as determined by the General Partner. Any adjustments to GP-Related Net Income (Loss) by the General Partner, including adjustments for items of income accrued but not yet received, unrealized gains, items of expense accrued but not yet paid, unrealized losses, reserves (including reserves for taxes, bad debts, actual or threatened litigation, or any other expenses, contingencies or obligations) and other appropriate items shall be made in accordance with GAAP; provided, that the General Partner shall not be required to make any such adjustment.

(d) An accounting period shall be a Fiscal Year, except that, at the option of the General Partner, an accounting period will terminate and a new accounting period will begin on the admission date of an additional Partner or the Settlement Date of a Withdrawn Partner, if any such date is not the first day of a Fiscal Year. If any event referred to in the preceding sentence occurs and the General Partner does not elect to terminate an accounting period and begin a new accounting period, then the General Partner may make such adjustments as it deems appropriate to the Partners’ GP-Related Profit Sharing Percentages for the accounting period in which such event occurs (prior to any allocations of GP-Related Unallocated Percentages or adjustments to GP-Related Profit Sharing Percentages pursuant to Section 5.3) to reflect the Partners’ average GP-Related Profit Sharing Percentages during such accounting period; provided, that the GP-Related Profit Sharing Percentages of Partners in GP-Related Net Income (Loss) from GP-Related Investments acquired during such accounting period will be based on GP-Related Profit Sharing Percentages in effect when each such GP-Related Investment was acquired.

(e) In establishing GP-Related Profit Sharing Percentages and allocating GP-Related Unallocated Percentages pursuant to Section 5.3, the General Partner may consider such factors as it deems appropriate.

(f) All determinations, valuations and other matters of judgment required to be made for accounting purposes under this Agreement shall be made by the General Partner and approved by the Partnership’s independent accountants. Such approved determinations, valuations and other accounting matters shall be conclusive and binding on all Partners, all Withdrawn Partners, their successors, heirs, estates or legal representatives and any other person, and to the fullest extent permitted by law no such person shall have the right to an accounting or an appraisal of the assets of the Partnership or any successor thereto.

Section 5.2. GP-Related Capital Accounts.

(a) There shall be established for each Partner in the books of the Partnership, to the extent and at such times as may be appropriate, one or more capital accounts as the General Partner may deem to be appropriate for purposes of accounting for such Partner’s interests in the capital of the Partnership related to the GP-Related SP Infrastructure III Interest and the GP-Related Net Income (Loss) of the Partnership (each a “GP-Related Capital Account”).

(b) As of the end of each accounting period or, in the case of a contribution to the Partnership by one or more of the Partners with respect to such Partner or Partners’ GP-Related Partner Interests or a distribution by the Partnership to one or more of the Partners with respect to such Partner or Partners’ GP-Related Partner Interests, at the time of such contribution or distribution, (i) the appropriate GP-Related Capital Accounts of each Partner shall be credited with the following amounts: (A) the amount of cash and the value of any property contributed by such Partner to the capital of the Partnership related to such Partner’s GP-Related Partner Interest during such accounting period, (B) the GP-Related Net Income allocated to such Partner for such accounting period and (C) the interest credited on the balance of such Partner’s capital related to such Partner’s GP-Related Partner Interest for such accounting period pursuant to Section 4.2; and (ii) the appropriate GP-Related Capital Accounts of each Partner shall be debited with the following amounts: (x) the amount of cash, the principal amount of any subordinated promissory note of the Partnership referred to in Section 6.5 (as such amount is paid) and the value of any property distributed to such Partner during such accounting period with respect to such Partner’s GP-Related Partner Interest and (y) the GP-Related Net Loss allocated to such Partner for such accounting period.

Section 5.3. GP-Related Profit Sharing Percentages.

(a) Prior to the beginning of each annual accounting period, the General Partner shall establish the profit sharing percentage (the “GP-Related Profit Sharing Percentage”) of each Partner in each category of GP-Related Net Income (Loss) for such annual accounting period pursuant to Section 5.1(a) taking into account such factors as the General Partner deems appropriate; provided, that (i) the General Partner may elect to establish GP-Related Profit Sharing Percentages in GP-Related Net Income (Loss) from any GP-Related Investment acquired by the Partnership during such accounting period at the time such GP-Related Investment is acquired in accordance with paragraph (c) below and (ii) GP-Related Net Income (Loss) for such accounting period from any GP-Related Investment shall be allocated in accordance with the GP-Related Profit Sharing Percentages in such GP-Related Investment established in accordance with paragraph (c) below. The General Partner may establish different GP-Related Profit Sharing Percentages for any Partner in different categories of GP-Related Net Income (Loss). In the case of the Withdrawal of a Partner, such former Partner’s GP-Related Profit Sharing Percentages shall be allocated by the General Partner to one or more of the remaining Partners as the General Partner shall determine. In the case of the admission of any Partner to the Partnership as an additional Partner, the GP-Related Profit Sharing Percentages of the other Partners shall be reduced by an amount equal to the GP-Related Profit Sharing Percentage allocated to such new Partner pursuant to Section 6.1(b); such reduction of each other Partner’s GP-Related Profit Sharing Percentage shall be pro rata based upon such Partner’s GP-Related Profit Sharing Percentage as in effect immediately prior to the admission of the new Partner. Notwithstanding the foregoing, the General Partner may also adjust the GP-Related Profit Sharing Percentage of any Partner for any annual accounting period at the end of such annual accounting period in its sole discretion.

(b) The General Partner may elect to allocate to the Partners less than 100% of the GP-Related Profit Sharing Percentages of any category for any annual accounting period at the time specified in Section 5.3(a) for the annual fixing of GP-Related Profit Sharing Percentages (any remainder of such GP-Related Profit Sharing Percentages being called a “GP-Related Unallocated Percentage”); provided, that any GP-Related Unallocated Percentage in any category of GP-Related Net Income (Loss) for any annual accounting period that is not allocated by the General Partner within 90 days after the end of such accounting period shall be deemed to be allocated among all the Partners (including the General Partner) in the manner determined by the General Partner in its sole discretion.

(c) Unless otherwise determined by the General Partner in a particular case, (i) GP-Related Profit Sharing Percentages in GP-Related Net Income (Loss) from any GP-Related Investment shall be allocated in proportion to the Partners’ respective GP-Related Capital Contributions in respect of such GP-Related Investment and (ii) GP-Related Profit Sharing Percentages in GP-Related Net Income (Loss) from each GP-Related Investment shall be fixed at the time such GP-Related Investment is acquired and shall not thereafter change, subject to any repurchase rights established by the General Partner pursuant to Section 5.7.

Section 5.4. Allocations of GP-Related Net Income (Loss) .

(a) Except as provided in Section 5.4(d), GP-Related Net Income of the Partnership for each GP-Related Investment shall be allocated to the GP-Related Capital Accounts related to such GP-Related Investment of all the Partners participating in such GP-Related Investment (including the General Partner): first, in proportion to and to the extent of the amount of Non-Carried Interest (other than amounts representing a return of GP-Related Capital Contributions) or Carried Interest distributed to the Partners; second, to Partners that received Non-Carried Interest (other than amounts representing a return of GP-Related Capital Contributions) or Carried Interest in years prior to the years such GP-Related Net Income is being allocated to the extent such Non-Carried Interest (other than amounts representing a return of GP-Related Capital Contributions) or Carried Interest exceeded GP-Related Net Income allocated to such Partners in such earlier years; and third, to the Partners in the same manner that such Non-Carried Interest (other than amounts representing a return of GP-Related Capital Contributions) or Carried Interest would have been distributed if cash were available to distribute with respect thereto.

(b) GP-Related Net Loss of the Partnership shall be allocated as follows: (i) GP-Related Net Loss relating to realized losses suffered by SP Infrastructure III and allocated to the Partnership with respect to its pro rata share thereof (based on capital contributions made by the Partnership to SP Infrastructure III with respect to the GP-Related SP Infrastructure III Interest) shall be allocated to the Partners in accordance with each Partner’s Non-Carried Interest Sharing Percentage with respect to the GP-Related Investment giving rise to such loss suffered by SP Infrastructure III and (ii) GP-Related Net Loss relating to realized losses suffered by SP Infrastructure III and allocated to the Partnership with respect to the Carried Interest shall be allocated in accordance with a Partner’s (including a Withdrawn Partner’s) Carried Interest Give Back Percentage (as of the date of such loss) (subject to adjustment pursuant to Section 5.8(e)).

(c) Notwithstanding Section 5.4(a) above, GP-Related Net Income relating to Carried Interest allocated after the allocation of a GP-Related Net Loss pursuant to clause (ii) of Section 5.4(b) shall be allocated in accordance with such Carried Interest Give Back Percentages until such time as the Partners have been allocated GP-Related Net Income relating to Carried Interest equal to the aggregate amount of GP-Related Net Loss previously allocated in accordance with clause (ii) of Section 5.4(b). Withdrawn Partners shall remain Partners for purposes of allocating such GP-Related Net Loss with respect to Carried Interest.

(d) To the extent the Partnership has any GP-Related Net Income (Loss) for any accounting period unrelated to SP Infrastructure III, such GP-Related Net Income (Loss) will be allocated in accordance with GP-Related Profit Sharing Percentages prevailing at the beginning of such accounting period.

(e) The General Partner may authorize from time to time advances to Partners (including any additional Partner admitted to the Partnership pursuant to Section 6.1 but excluding any Partners who are also executive officers of The Blackstone Group Inc. or any Affiliate thereof) against their allocable shares of GP-Related Net Income (Loss).

(f) 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 facts and circumstances as the General Partner deems reasonably necessary for this purpose.

Section 5.5. Liability of Partners. Except as otherwise provided in the Partnership Act or as expressly provided in this Agreement, no Partner shall be personally obligated for any debt, obligation or liability of the Partnership or of any other Partner solely by reason of being a Partner. In no event shall any Partner or Withdrawn Partner (i) be obligated to make any capital contribution or payment to or on behalf of the Partnership or (ii) have any liability to return distributions received by such Partner from the Partnership, in each case except as specifically provided in Section 4.1(d) or Section 5.8 or otherwise in this Agreement, as such Partner shall otherwise expressly agree in writing or as may be required by applicable law.

Section 5.6. [Intentionally Omitted].

Section 5.7. Repurchase Rights, etc. The General Partner may from time to time establish such repurchase rights and/or other requirements with respect to the Partners’ GP-Related Partner Interests relating to GP-Related SP Infrastructure III Investments as the General Partner may determine. The General Partner shall have authority to (a) withhold any distribution otherwise payable to any Partner until any such repurchase rights have lapsed or any such requirements have been satisfied, (b) pay any distribution to any Partner that is Contingent as of the distribution date and require the refund of any portion of such distribution that is Contingent as of the Withdrawal Date of such Partner, (c) amend any previously established repurchase rights or other requirements from time to time and (d) make such exceptions thereto as it may determine on a case by case basis.

Section 5.8. Distributions.

(a) (i) The Partnership shall make distributions of available cash (subject to reserves and other adjustments as provided herein) or other property to Partners with respect to such Partners’ GP-Related Partner Interests at such times and in such amounts as are determined by the General Partner. The General Partner shall, if it deems it appropriate, determine the availability for distribution of, and distribute, cash or other property separately for each category of GP-Related Net Income (Loss) established pursuant to Section 5.1(a). Distributions of cash or other property with respect to Non-Carried Interest shall be made among the Partners in accordance with their respective Non-Carried Interest Sharing Percentages, and, subject to Section 4.1(d) and Section 5.8(e), distributions of cash or other property with respect to Carried Interest shall be made among Partners in accordance with their respective Carried Interest Sharing Percentages.

(ii) At any time that a sale, exchange, transfer or other disposition by SP Infrastructure III of a portion of a GP-Related Investment is being considered by the Partnership (a “GP-Related Disposable Investment”), at the election of the General Partner each Partner’s GP-Related Partner Interest with respect to such GP-Related Investment shall be vertically divided into two separate GP-Related Partner Interests, a GP-Related Partner Interest attributable to the GP-Related Disposable Investment (a Partner’s “GP-Related Class B Interest”), and a GP-Related Partner Interest attributable to such GP-Related Investment excluding the GP-Related Disposable Investment (a Partner’s “GP-Related Class A Interest”). Distributions (including those resulting from a sale, transfer, exchange or other disposition by SP Infrastructure III) relating to a GP-Related Disposable Investment (with respect to both Carried Interest and Non-Carried Interest) shall be made only to holders of GP-Related Class B Interests with respect to such GP-Related Investment in accordance with their GP-Related Profit Sharing Percentages relating to such GP-Related Class B Interests, and distributions (including those resulting from the sale, transfer, exchange or other disposition by SP Infrastructure III) relating to a GP-Related Investment excluding such GP-Related Disposable Investment (with respect to both Carried Interest and Non-Carried Interest) shall be made only to holders of GP-Related Class A Interests with respect to such GP-Related Investment in accordance with their respective GP-Related Profit Sharing Percentages relating to such GP-Related Class A Interests. Except as provided above, distributions of cash or other property with respect to each category of GP-Related Net Income (Loss) shall be allocated among the Partners in the same proportions as the allocations of GP-Related Net Income (Loss) of each such category.

(b) Subject to the Partnership’s having sufficient available cash in the reasonable judgment of the General Partner, the Partnership shall make cash distributions to each Partner with respect to each Fiscal Year of the Partnership in an aggregate amount at least equal to the total U.S. federal, New York State and New York City income and other taxes that would be payable by such Partner with respect to all categories of GP-Related Net Income (Loss) allocated to such Partner for such Fiscal Year, the amount of which shall be calculated (i) on the

assumption that each Partner is an individual subject to the then prevailing maximum rate of U.S. federal, New York State and New York City and other income taxes (including, without limitation, taxes under Sections 1401 and 1411 of the Code), (ii) taking into account (x) the limitations on the deductibility of expenses and other items for U.S. federal income tax purposes and (y) the character (e.g., long-term or short-term capital gain or ordinary or exempt) of the applicable income, and (iii) taking into account any differential in applicable rates due to the type and character of GP-Related Net Income (Loss) allocated to such Partner. Notwithstanding the provisions of the foregoing sentence, the General Partner may refrain from making any distribution if, in the reasonable judgment of the General Partner, such distribution is prohibited by applicable law.

(c) The General Partner may provide that the GP-Related Partner Interest of any Partner or employee (including such Partner’s or employee’s right to distributions and investments of the Partnership related thereto) may be subject to repurchase by the Partnership during such period as the General Partner shall determine (a “Repurchase Period”). Any Contingent distributions from GP-Related Investments subject to repurchase rights will be withheld by the Partnership and will be distributed to the recipient thereof (together with interest thereon at rates determined by the General Partner from time to time) as the recipient’s rights to such distributions become Non-Contingent (by virtue of the expiration of the applicable Repurchase Period or otherwise). The General Partner may elect in an individual case to have the Partnership distribute any Contingent distribution to the applicable recipient thereof irrespective of whether the applicable Repurchase Period has lapsed. If a Partner Withdraws from the Partnership for any reason other than his or her death, Total Disability or Incompetence, the undistributed share of any GP-Related Investment that remains Contingent as of the applicable Withdrawal Date shall be repurchased by the Partnership at a purchase price determined at such time by the General Partner. Unless determined otherwise by the General Partner, the repurchased portion thereof will be allocated among the remaining Partners with interests in such GP-Related Investment in proportion to their respective percentage interests in such GP-Related Investment, or if no other Partner has a percentage interest in such specific GP-Related Investment, to the General Partner; provided, that the General Partner may allocate the Withdrawn Partner’s share of unrealized investment income from a repurchased GP-Related Investment attributable to the period after the Withdrawn Partner’s Withdrawal Date on any basis it may determine, including to existing or new Partners who did not previously have interests in such GP-Related Investment, except that, in any event, each Investor Special Partner shall be allocated a share of such unrealized investment income equal to its respective GP-Related Profit Sharing Percentage of such unrealized investment income.

(d) (i) (A) If the Partnership is obligated under the Clawback Provisions or Giveback Provisions to contribute to SP Infrastructure III a Clawback Amount or a Giveback Amount (other than a Capital Commitment Giveback Amount) in respect of the GP-Related SP Infrastructure III Interest (the amount of any such obligation of the Partnership with respect to such a Giveback Amount being herein called a “GP-Related Giveback Amount”), the General Partner shall call for such amounts as are necessary to satisfy such obligations of the Partnership as determined by the General Partner, in which case each Partner and Withdrawn Partner shall contribute to the Partnership, in cash, when and as called by the General Partner, such an amount of prior distributions by the Partnership (and the Other Fund GPs) with respect to Carried Interest (and/or Non-Carried Interest in the case of a GP-Related Giveback Amount) (the “GP-

Related Recontribution Amount”) which equals (I) the product of (a) a Partner’s or Withdrawn Partner’s Carried Interest Give Back Percentage and (b) the aggregate Clawback Amount payable by the Partnership in the case of Clawback Amounts and (II) with respect to a GP-Related Giveback Amount, such Partner’s pro rata share of prior distributions of Carried Interest and/or Non-Carried Interest in connection with (a) the GP-Related SP Infrastructure III Investment giving rise to the GP-Related Giveback Amount, (b) if the amounts contributed pursuant to clause (II)(a) above are insufficient to satisfy such GP-Related Giveback Amount, GP-Related SP Infrastructure III Investments other than the one giving rise to such obligation, but only those amounts received by the Partners with an interest in the GP-Related SP Infrastructure III Investment referred to in clause (II)(a) above, and (c) if the GP-Related Giveback Amount pursuant to an applicable SP Infrastructure III Agreement is unrelated to a specific GP-Related SP Infrastructure III Investment, all GP-Related SP Infrastructure III Investments. Each Partner and Withdrawn Partner shall promptly contribute to the Partnership, along with satisfying his or her comparable obligations to the Other Fund GPs, if any, upon such call such Partner’s or Withdrawn Partner’s GP-Related Recontribution Amount, less the amount paid out of the Trust Account on behalf of such Partner or Withdrawn Partner by the Trustee(s) pursuant to written instructions from the Partnership, or if applicable, any of the Other Fund GPs with respect to Carried Interest (and/or Non-Carried Interest in the case of GP-Related Giveback Amounts) (the “Net GP-Related Recontribution Amount”), irrespective of the fact that the amounts in the Trust Account may be sufficient on an aggregate basis to satisfy the Partnership’s and the Other Fund GPs’ obligation under the Clawback Provisions and/or Giveback Provisions; provided, that to the extent a Partner’s or Withdrawn Partner’s share of the amount paid with respect to the Clawback Amount or the GP-Related Giveback Amount exceeds his or her GP-Related Recontribution Amount, such excess shall be repaid to such Partner or Withdrawn Partner as promptly as reasonably practicable, subject to clause (ii) below; provided further, that such written instructions from the General Partner shall specify each Partner’s and Withdrawn Partner’s GP-Related Recontribution Amount. Prior to such time, the General Partner may, in its discretion (but shall be under no obligation to), provide notice that in the General Partner’s judgment, the potential obligations in respect of the Clawback Provisions or the Giveback Provisions will probably materialize (and an estimate of the aggregate amount of such obligations); provided further, that any amount from a Partner’s Trust Account used to pay any GP-Related Giveback Amount (or such lesser amount as may be required by the General Partner) shall be contributed by such Partner to such Partner’s Trust Account no later than 30 days after the Net GP-Related Recontribution Amount is paid with respect to such GP-Related Giveback Amount.

(B) To the extent any Partner or Withdrawn Partner has satisfied any Holdback obligation with Firm Collateral, such Partner or Withdrawn Partner shall, within 10 days of the General Partner’s call for GP-Related Recontribution Amounts, make a cash payment into the Trust Account in an amount equal to the amount of the Holdback obligation satisfied with such Firm Collateral, or such lesser amount such that the amount in the Trust Account allocable to such Partner or Withdrawn Partner equals the sum of (I) such Partner’s or Withdrawn Partner’s GP-Related Recontribution Amount and (II) any similar amounts payable to any of the Other Fund GPs. Immediately upon receipt of such cash, the Trustee(s) shall take such steps as are necessary to release such Firm Collateral of such Partner or Withdrawn Partner equal to the amount of such cash payment. If the

amount of such cash payment is less than the amount of Firm Collateral of such Partner or Withdrawn Partner, the balance of such Firm Collateral if any, shall be retained to secure the payment of GP-Related Deficiency Contributions, if any, and shall be fully released upon the satisfaction of the Partnership’s and the Other Fund GPs’ obligation to pay the Clawback Amount. The failure of any Partner or Withdrawn Partner to make a cash payment in accordance with this clause (B) (to the extent applicable) shall constitute a default under Section 5.8(d)(ii) as if such cash payment hereunder constitutes a Net GP-Related Recontribution Amount under Section 5.8(d)(ii). Solely to the extent required by the SP Infrastructure III Partnership Agreement, each partner of the General Partner shall have the same obligations as a Partner (which obligations shall be subject to the same limitations as the obligations of a Partner) under this Section 5.8(d)(i)(B) and under Section 5.8(d)(ii)(A) with respect to such partner’s pro rata share of any Clawback Amount and solely to the extent that the Partnership has insufficient funds to meet the Partnership’s obligations under the SP Infrastructure III Partnership Agreement.

(ii) (A) In the event any Partner or Withdrawn Partner (a “GP-Related Defaulting Party”) fails to recontribute all or any portion of such GP-Related Defaulting Party’s Net GP-Related Recontribution Amount for any reason, the General Partner shall (i) use its reasonable efforts to collect any amounts from any such GP-Related Defaulting Party and (ii) require all other Partners and Withdrawn Partners to contribute, on a pro rata basis (based on each of their respective Carried Interest Give Back Percentages in the case of Clawback Amounts, and GP-Related Profit Sharing Percentages in the case of GP-Related Giveback Amounts (as more fully described in clause (II) of Section 5.8(d)(i)(A) above)), such amounts as are necessary to fulfill the GP-Related Defaulting Party’s obligation to pay such GP-Related Defaulting Party’s Net GP-Related Recontribution Amount (a “GP-Related Deficiency Contribution”) if the General Partner determines in its good faith judgment that the Partnership (or an Other Fund GP) will be unable to collect such amount in cash from such GP-Related Defaulting Party for payment of the Clawback Amount or GP-Related Giveback Amount, as the case may be, at least 20 Business Days prior to the latest date that the Partnership, and the Other Fund GPs, if applicable, are permitted to pay the Clawback Amount or GP-Related Giveback Amount, as the case may be; provided, that, subject to Section 5.8(e), no Partner or Withdrawn Partner shall as a result of such GP-Related Deficiency Contribution be required to contribute an amount in excess of 150% of the amount of the Net GP Related Recontribution Amount initially requested from such Partner or Withdrawn Partner in respect of such default.

(B) Thereafter, the General Partner shall determine in its good faith judgment that the Partnership should either (1) not attempt to collect such amount in light of the costs associated therewith, the likelihood of recovery and any other factors considered relevant in the good faith judgment of the General Partner or (2) pursue any and all remedies (at law or equity) available to the Partnership against the GP-Related Defaulting Party, the cost of which shall be a Partnership expense to the extent not ultimately reimbursed by the GP-Related Defaulting Party. It is agreed that the Partnership shall have the right (effective upon such

GP-Related Defaulting Party becoming a GP-Related Defaulting Party) to set-off as appropriate and apply against such GP-Related Defaulting Party’s Net GP-Related Recontribution Amount any amounts otherwise payable to the GP-Related Defaulting Party by the Partnership or any Affiliate thereof (including amounts unrelated to Carried Interest, such as returns of capital and profit thereon). Each Partner and Withdrawn Partner hereby grants to the General Partner a security interest, effective upon such Partner or Withdrawn Partner becoming a GP-Related Defaulting Party, in all accounts receivable and other rights to receive payment from any Affiliate of the Partnership and agrees that, upon the effectiveness of such security interest, the General Partner may sell, collect or otherwise realize upon such collateral. In furtherance of the foregoing, each Partner and Withdrawn Partner hereby appoints the General Partner as its true and lawful attorney-in-fact with full irrevocable power and authority, in the name of such Partner or Withdrawn Partner or in the name of the General Partner, to take any actions which may be necessary to accomplish the intent of the immediately preceding sentence. The General Partner shall be entitled to collect interest on the Net GP-Related Recontribution Amount of a GP-Related Defaulting Party from the date such Net GP-Related Recontribution Amount was required to be contributed to the Partnership at a rate equal to the Default Interest Rate.

(C) Any Partner’s or Withdrawn Partner’s failure to make a GP-Related Deficiency Contribution shall cause such Partner or Withdrawn Partner to be a GP-Related Defaulting Party with respect to such amount. The Partnership shall first seek any remaining Trust Amounts (and Trust Income thereon) allocated to such Partner or Withdrawn Partner to satisfy such Partner’s or Withdrawn Partner’s obligation to make a GP-Related Deficiency Contribution before seeking cash contributions from such Partner or Withdrawn Partner in satisfaction of such Partner’s or Withdrawn Partner’s obligation to make a GP-Related Deficiency Contribution.

(iii) In the event any Partner or Withdrawn Partner initially fails to recontribute all or any portion of such Partner or Withdrawn Partner’s pro rata share of any Clawback Amount pursuant to Section 5.8(d)(i)(A), the Partnership shall use its reasonable efforts to collect the amount which such Partner or Withdrawn Partner so fails to recontribute.

(iv) A Partner’s or Withdrawn Partner’s obligation to make contributions to the Partnership under this Section 5.8(d) shall survive the termination of the Partnership.

(e) The Partners acknowledge that the General Partner will (and is hereby authorized to) take such steps as it deems appropriate, in its good faith judgment, to further the objective of providing for the fair and equitable treatment of all Partners, including by allocating Losses (as defined in the SP Infrastructure III Agreements) on GP-Related SP Infrastructure III Investments that have been the subject of a writedown and/or losses (each, a “Loss Investment”) to those Partners who participated in such Loss Investments based on their Carried Interest Sharing Percentage therein to the extent that such Partners receive or have received Carried Interest distributions from other GP-Related SP Infrastructure III Investments. Consequently and notwithstanding anything herein to the contrary, adjustments to Carried Interest distributions shall be made as set forth in this Section 5.8(e).

(i) At the time the Partnership is making Carried Interest distributions in connection with a GP-Related SP Infrastructure III Investment (the “Subject Investment”) that have been reduced under any SP Infrastructure III Agreement as a result of one or more Loss Investments, the General Partner shall calculate amounts distributable to or due from each such Partner as follows:

(A) determine each Partner’s share of each such Loss Investment based on his or her Carried Interest Sharing Percentage in each such Loss Investment (which may be zero) to the extent such Loss Investment has reduced the Carried Interest distributions otherwise available for distribution to all Partners (indirectly through the Partnership from SP Infrastructure III) from the Subject Investment (such reduction, the “Loss Amount”);

(B) determine the amount of Carried Interest distributions otherwise distributable to such Partner with respect to the Subject Investment (indirectly through the Partnership from SP Infrastructure III) before any reduction in respect of the amount determined in clause (A) above (the “Unadjusted Carried Interest Distributions”); and

(C) subtract (I) the Loss Amounts relating to all Loss Investments from (II) the Unadjusted Carried Interest Distributions for such Partner, to determine the amount of Carried Interest distributions to actually be paid to such Partner (“Net Carried Interest Distribution”).

To the extent that the Net Carried Interest Distribution for a Partner as calculated in this clause (i) is a negative number, the General Partner shall (I) notify such Partner, at or prior to the time such Carried Interest distributions are actually made to the Partners, of his or her obligation to recontribute to the Partnership prior Carried Interest distributions (a “Net Carried Interest Distribution Recontribution Amount”), up to the amount of such negative Net Carried Interest Distribution and (II) to the extent amounts recontributed pursuant to clause (I) are insufficient to satisfy such negative Net Carried Interest Distribution amount, reduce future Carried Interest distributions otherwise due such Partner, up to the amount of such remaining negative Net Carried Interest Distribution. If a Partner’s (x) Net Carried Interest Distribution Recontribution Amount exceeds (y) the aggregate amount of prior Carried Interest distributions less the amount of tax thereon, calculated based on the Assumed Income Tax Rate (as defined in the SP Infrastructure III Agreements) in effect in the Fiscal Years of such distributions (the “Excess Tax-Related Amount”), then such Partner may, in lieu of paying such Partner’s Excess Tax-Related Amount, defer such amounts as set forth below. Such deferred amount shall accrue interest at the Prime Rate. Such deferred amounts shall be reduced and repaid by the amount of Carried Interest otherwise distributable to such Partner in connection with future Carried Interest distributions until such balance is reduced to zero. Any deferred amounts shall be payable in full upon the earlier of (i) such time as the Clawback Amount is determined (as provided herein) and (ii) such time as the Partner becomes a Withdrawn Partner.

To the extent there is an amount of negative Net Carried Interest Distribution with respect to a Partner remaining after the application of this clause (i), notwithstanding clause (II) of the preceding paragraph, such remaining amount of negative Net Carried Interest Distribution shall be allocated to the other Partners pro rata based on each of their Carried Interest Sharing Percentages in the Subject Investment.

A Partner who fails to pay a Net Carried Interest Distribution Recontribution Amount promptly upon notice from the General Partner (as provided above) shall be deemed a GP-Related Defaulting Party for all purposes hereof.

A Partner may satisfy in part any Net Carried Interest Distribution Recontribution Amount from cash that is then subject to a Holdback, to the extent that the amounts that remain subject to a Holdback satisfy the Holdback requirements hereof as they relate to the reduced amount of aggregate Carried Interest distributions received by such Partner (taking into account any Net Carried Interest Distribution Recontribution Amount contributed to the Partnership by such Partner).

Any Net Carried Interest Distribution Recontribution Amount contributed by a Partner, including amounts of cash subject to a Holdback as provided above, shall increase the amount available for distribution to the other Partners as Carried Interest distributions with respect to the Subject Investment; provided, that any such amounts then subject to a Holdback may be so distributed to the other Partners to the extent a Partner receiving such distribution has satisfied the Holdback requirements with respect to such distribution (taken together with the other Carried Interest distributions received by such Partner to date).

(ii) In the case of Clawback Amounts which are required to be contributed to the Partnership as otherwise provided herein, the obligation of the Partners with respect to any Clawback Amount shall be adjusted by the General Partner as follows:

(A) determine each Partner’s share of any Losses (as defined in the SP Infrastructure III Agreements) in any GP-Related SP Infrastructure III Investments which gave rise to the Clawback Amount (i.e., the Losses that followed the last GP-Related SP Infrastructure III Investment with respect to which Carried Interest distributions were made), based on such Partner’s Carried Interest Sharing Percentage in such GP-Related SP Infrastructure III Investments;

(B) determine each Partner’s obligation with respect to the Clawback Amount based on such Partner’s Carried Interest Give Back Percentage as otherwise provided herein; and

(C) subtract the amount determined in clause (B) above from the amount determined in clause (A) above with respect to each Partner to determine the amount of adjustment to each Partner’s share of the Clawback Amount (a Partner’s “Clawback Adjustment Amount”).

A Partner’s share of the Clawback Amount shall for all purposes hereof be decreased by such Partner’s Clawback Adjustment Amount, to the extent it is a negative number (except to the extent expressly provided below). A Partner’s share of the Clawback Amount shall for all purposes hereof be increased by such Partner’s Clawback Adjustment Amount (to the extent it is a positive number); provided, that in no way shall a Partner’s aggregate obligation to satisfy a Clawback Amount as a result of this clause (ii) exceed the aggregate Carried Interest distributions received by such Partner. To the extent a positive Clawback Adjustment Amount remains after the application of this clause (ii) with respect to a Partner, such remaining Clawback Adjustment Amount shall be allocated to the Partners (including any Partner whose Clawback Amount was increased pursuant to this clause (ii)) pro rata based on their Carried Interest Give Back Percentages (determined without regard to this clause (ii)).

Any distribution or contribution adjustments pursuant to this Section 5.8(e) by the General Partner shall be based on its good faith judgment, and no Partner shall have any claim against the Partnership, the General Partner or any other Partners as a result of any adjustment made as set forth above. This Section 5.8(e) applies to all Partners, including Withdrawn Partners.

It is agreed and acknowledged that this Section 5.8(e) is an agreement among the Partners and in no way modifies the obligations of each Partner regarding the Clawback Amount as provided in the SP Infrastructure III Agreements.

Section 5.9. Business Expenses. The Partnership shall reimburse the Partners for reasonable travel, entertainment and miscellaneous expenses incurred by them in the conduct of the Partnership’s business in accordance with rules and regulations established by the General Partner from time to time.

Section 5.10. Tax Capital Accounts; Tax Allocations.

(a) For U.S. federal income tax purposes, there shall be established for each Partner a single capital account combining such Partner’s Capital Commitment Capital Account and GP-Related Capital Account, with such adjustments as the General Partner determines are appropriate so that such single capital account is maintained in compliance with the principles and requirements of Section 704(b) of the Code and the Treasury Regulations thereunder.

(b) All items of income, gain, loss, deduction and credit of the Partnership shall be allocated among the Partners for U.S. federal, state and local income tax purposes in the same manner as such items of income, gain, loss, deduction and credit shall be allocated among the Partners pursuant to this Agreement, except as may otherwise be provided herein or by the Code or other applicable law. In the event 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 taxable year of the Partnership, each Partner shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to its respective share 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). In addition, this Agreement shall be considered to contain a “qualified income offset” as provided in Treasury Regulations Section 1.704-1(b)(2)(ii)(d). Notwithstanding the foregoing, the General Partner in its sole discretion shall make allocations for tax purposes as may be needed to ensure that allocations are in accordance with the interests of the Partners within the meaning of the Code and the Treasury Regulations.

(c) For U.S. federal, state and local income tax purposes only, Partnership income, gain, loss, deduction or expense (or any item thereof) for each Fiscal Year shall be allocated to and among the Partners in a manner corresponding to the manner in which corresponding items are allocated among the Partners pursuant to the other provisions of this Section 5.10; provided, that the General Partner may in its sole discretion make such allocations for tax purposes as it determines are appropriate so that allocations have substantial economic effect or are in accordance with the interests of the Partners, within the meaning of the Code and the Treasury Regulations thereunder. 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.

ARTICLE VI

ADDITIONAL PARTNERS; WITHDRAWAL OF PARTNERS;

SATISFACTION AND DISCHARGE OF

PARTNERSHIP INTERESTS; TERMINATION

Section 6.1. Additional Partners.

(a) Effective on the first day of any month (or on such other date as shall be determined by the General Partner in its sole discretion), the General Partner shall have the right to admit one or more additional or substitute persons into the Partnership as Limited Partners or Special Partners. Each such person shall make the representations and certifications with respect to itself set forth in Section 3.6 and Section 3.7. The General Partner shall determine and negotiate with the additional Partner (which term shall include, without limitation, any substitute Partner) all terms of such additional Partner’s participation in the Partnership, including the additional Partner’s initial GP-Related Capital Contribution, Capital Commitment-Related Capital Contribution, GP-Related Profit Sharing Percentage and Capital Commitment Profit Sharing Percentage. Each additional Partner shall have such voting rights as may be determined by the General Partner from time to time unless, upon the admission to the Partnership of any Special Partner, the General Partner shall designate that such Special Partner shall not have such voting rights (any such Special Partner being called a “Nonvoting Special Partner”). Any additional Partner shall, as a condition to becoming a Partner, agree to become a party to, and be bound by the terms and conditions of, the Trust Agreement. If Blackstone or another or subsequent holder of an Investor Note approved by the General Partner for purposes of this Section 6.1(a) shall foreclose upon a Limited Partner’s Investor Note issued to finance such Limited Partner’s purchase of his or her Capital Commitment Interests, Blackstone or such other or subsequent holder shall succeed to such Limited Partner’s Capital Commitment Interests and shall be deemed to have become a Limited Partner to such extent. Any additional Partner may have a GP-Related Partner Interest or a Capital Commitment Partner Interest, without having the other such interest.

(b) The GP-Related Profit Sharing Percentages, if any, to be allocated to an additional Partner as of the date such Partner is admitted to the Partnership, together with the pro rata reduction in all other Partners’ GP-Related Profit Sharing Percentages as of such date, shall be established by the General Partner pursuant to Section 5.3. The Capital Commitment Profit Sharing Percentages, if any, to be allocated to an additional Partner as of the date such Partner is admitted to the Partnership, together with the pro rata reduction in all other Partners’ Capital Commitment Profit Sharing Percentages as of such date, shall be established by the General Partner. Notwithstanding any provision in this Agreement to the contrary, the General Partner is authorized, without the need for any further act, vote or consent of any person, to make adjustments to the GP-Related Profit Sharing Percentages as it determines necessary in its sole discretion in connection with any additional Partners admitted to the Partnership, adjustments with respect to other Partners of the Partnership and to give effect to other matters set forth herein, as applicable.

(c) An additional Partner shall be required to contribute to the Partnership his or her pro rata share of the Partnership’s total capital, excluding capital in respect of GP-Related Investments and Capital Commitment Investments in which such Partner does not acquire any interests, at such times and in such amounts as shall be determined by the General Partner in accordance with Section 4.1 and Section 7.1.

(d) The admission of an additional Partner will be evidenced by (i) the execution of a counterpart copy of this Agreement by such additional Partner, (ii) the execution of an amendment to this Agreement by the General Partner and the additional Partner, as determined by the General Partner and / or (iii) the execution by such additional Partner of any other writing evidencing the intent of such person to become an additional Partner and to be bound by the terms of this Agreement and such writing being acceptable to the General Partner on behalf of the Partnership. In addition, each additional Partner shall sign a counterpart copy of the Trust Agreement or any other writing evidencing the intent of such person to become a party to the Trust Agreement that is acceptable to the General Partner on behalf of the Partnership.

Section 6.2. Withdrawal of Partners.

(a) Any Partner may Withdraw voluntarily from the Partnership subject to the prior written consent of the General Partner, including if such Withdrawal would (i) cause the Partnership to be in default under any of its contractual obligations or (ii) in the reasonable judgment of the General Partner, have a material adverse effect on the Partnership or its business. Without limiting the foregoing sentence, the General Partner generally intends to permit voluntary Withdrawals on the last day of any calendar month (or on such other date as shall be determined by the General Partner in its sole discretion), on not less than 15 days’ prior written notice by such Partner to the General Partner (or on such shorter notice period as may be mutually agreed upon between such Partner and the General Partner); provided, that a Partner may Withdraw from the Partnership with respect to such Partner’s GP-Related Partner Interest without Withdrawing from the Partnership with respect to such Partner’s Capital Commitment Partner Interest, and a Partner may Withdraw from the Partnership with respect to such Partner’s Capital Commitment Partner Interest without Withdrawing from the Partnership with respect to such Partner’s GP-Related Partner Interest.

(b) Upon the Withdrawal of any Partner, including by the occurrence of any withdrawal event under the Partnership Act with respect to any Partner, such Partner shall thereupon cease to be a Partner, except as expressly provided herein.

(c) Upon the Total Disability of a Limited Partner, such Partner shall thereupon cease to be a Limited Partner with respect to such person’s GP-Related Partner Interest; provided, that the General Partner may elect to admit such Withdrawn Partner to the Partnership as a Nonvoting Special Partner with respect to such person’s GP-Related Partner Interest, with such GP-Related Partner Interest as the General Partner may determine. The determination of whether any Partner has suffered a Total Disability shall be made by the General Partner in its sole discretion after consultation with a qualified medical doctor. In the absence of agreement between the General Partner and such Partner, each party shall nominate a qualified medical doctor and the two doctors shall select a third doctor, who shall make the determination as to Total Disability.

(d) If the General Partner determines that it shall be in the best interests of the Partnership for any Partner (including any Partner who has given notice of voluntary Withdrawal pursuant to paragraph (a) above) to Withdraw from the Partnership (whether or not Cause exists) with respect to such person’s GP-Related Partner Interest and/or with respect to such person’s Capital Commitment Partner Interest, such Partner, upon written notice by the General Partner to such Partner, shall be required to Withdraw with respect to such person’s GP-Related Partner Interest and/or with respect to such person’s Capital Commitment Partner Interest, as of a date specified in such notice, which date shall be on or after the date of such notice. If the General Partner requires any Partner to Withdraw for Cause with respect to such person’s GP-Related Partner Interest and/or with respect to such person’s Capital Commitment Partner Interest, such notice shall state that it has been given for Cause and shall describe the particulars thereof in reasonable detail.

(e) The Withdrawal from the Partnership of any Partner shall not, in and of itself, affect the obligations of the other Partners to continue the Partnership during the remainder of its term. A Withdrawn General Partner shall remain liable for all obligations of the Partnership incurred while it was a General Partner and resulting from its acts or omissions as a General Partner to the fullest extent provided by law.

Section 6.3. GP-Related Partner Interests Not Transferable.

(a) No Partner may sell, assign, pledge, grant a security interest over or otherwise transfer or encumber all or any portion of such Partner’s GP-Related Partner Interest other than as permitted by written agreement between such Partner and the Partnership; provided, that this Section 6.3 shall not impair transfers by operation of law, transfers by will or by other testamentary instrument occurring by virtue of the death or dissolution of a Partner, or transfers required by trust agreements; provided further, that, subject to the prior written consent of the General Partner, which shall not be unreasonably withheld, a Limited Partner may transfer, for estate planning purposes, up to 25% of his or her GP-Related Profit Sharing

Percentage to any estate planning trust, limited partnership, or limited liability company with respect to which a Limited Partner controls investments related to any interest in the Partnership held therein (an “Estate Planning Vehicle”). Each Estate Planning Vehicle will be a Nonvoting Special Partner. Such Limited Partner and the Nonvoting Special Partner shall be jointly and severally liable for all obligations of both such Limited Partner and such Nonvoting Special Partner with respect to the Partnership (including the obligation to make additional GP-Related Capital Contributions), as the case may be. The General Partner may at its sole option exercisable at any time require any Estate Planning Vehicle to Withdraw from the Partnership on the terms of this Article VI. Except as provided in the second proviso to the first sentence of this Section 6.3, no assignee, legatee, distributee, heir or transferee (by conveyance, operation of law or otherwise) of the whole or any portion of any Partner’s GP-Related Partner Interest shall have any right to be a Partner without the prior written consent of the General Partner (which consent may be given or withheld in its sole discretion without giving any reason therefor). Notwithstanding the granting of a security interest in the entire Interest of any Partner, such Partner shall continue to be a Partner of the Partnership.

(b) Notwithstanding any provision hereof to the contrary, no sale or transfer of any GP-Related Partner Interest in the Partnership may be made except in compliance with all federal, state and other applicable laws, including U.S. federal and state securities laws.

Section 6.4. Consequences upon Withdrawal of a Partner.

(a) Subject to the Partnership Act, the General Partner may not transfer or assign its interest as a General Partner in the Partnership or its right to manage the affairs of the Partnership, except that the General Partner may, subject to the Partnership Act, with the prior written approval of a Majority in Interest of the Partners, admit another person as an additional or substitute General Partner who makes such representations with respect to itself as the General Partner deems necessary or appropriate (with regard to compliance with applicable law or otherwise); provided however, that the General Partner may, in its sole discretion, transfer all or part of its interest in the Partnership to a person who makes such representations with respect to itself as the General Partner deems necessary or appropriate (with regard to compliance with applicable law or otherwise) and who owns, directly or indirectly, the principal part of the business then conducted by the General Partner in connection with any liquidation, dissolution or reorganization of the General Partner, and, upon the assumption by such person of liability for all the obligations of the General Partner under this Agreement, such person shall be admitted as the General Partner. A person who is so admitted as an additional or substitute General Partner shall thereby become a General Partner and shall have the right to manage the affairs of the Partnership and to vote as a Partner to the extent of the interest in the Partnership so acquired. The General Partner shall not cease to be the general partner of the Partnership upon the collateral assignment of or the pledging or granting of a security interest in its entire Interest in the Partnership.

(b) Except as contemplated by Section 6.4(a) above, Withdrawal by a General Partner is not permitted. The Withdrawal of a Partner shall not dissolve the Partnership if at the time of such Withdrawal there are one or more remaining Partners and any one or more of such remaining Partners continue the business of the Partnership (any and all such remaining Partners being hereby authorized to continue the business of the Partnership without dissolution and

hereby agreeing to do so). Notwithstanding Section 6.4(c), if upon the Withdrawal of a Partner there shall be no remaining Limited Partners, the Partnership shall be dissolved and shall be wound up unless, within 90 days after the occurrence of such Withdrawal, all remaining Special Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of the date of such Withdrawal, of one or more Limited Partners.

(c) The Partnership shall not be dissolved, in and of itself, by the Withdrawal of any Partner, but shall continue with the surviving or remaining Partners as partners thereof in accordance with and subject to the terms and provisions of this Agreement.

Section 6.5. Satisfaction and Discharge of a Withdrawn Partner’s GP-Related Partner Interests.

(a) The terms of this Section 6.5 shall apply to the GP-Related Partner Interest of a Withdrawn Partner, but, except as otherwise expressly provided in this Section 6.5, shall not apply to the Capital Commitment Partner Interest of a Withdrawn Partner. For purposes of this Section 6.5, the term “Settlement Date” means the date as of which a Withdrawn Partner’s GP-Related Partner Interest in the Partnership is settled as determined under paragraph (b) below. Notwithstanding the foregoing, any Limited Partner who Withdraws from the Partnership, and all or any portion of whose GP-Related Partner Interest is retained as a Special Partner, shall be considered a Withdrawn Partner for all purposes hereof.

(b) Except where a later date for the settlement of a Withdrawn Partner’s GP-Related Partner Interest in the Partnership may be agreed to by the General Partner and a Withdrawn Partner, a Withdrawn Partner’s Settlement Date shall be his or her Withdrawal Date; provided, that if a Withdrawn Partner’s Withdrawal Date is not the last day of a month, then the General Partner may elect for such Withdrawn Partner’s Settlement Date to be the last day of the month in which his or her Withdrawal Date occurs. During the interval, if any, between a Withdrawn Partner’s Withdrawal Date and Settlement Date, such Withdrawn Partner shall have the same rights and obligations with respect to GP-Related Capital Contributions, interest on capital, allocations of GP-Related Net Income (Loss) and distributions as would have applied had such Withdrawn Partner remained a Partner of the Partnership during such period.

(c) In the event of the Withdrawal of a Partner, with respect to such Withdrawn Partner’s GP-Related Partner Interest, the General Partner shall promptly after such Withdrawn Partner’s Settlement Date (i) determine and allocate to the Withdrawn Partner’s GP-Related Capital Accounts such Withdrawn Partner’s allocable share of the GP-Related Net Income (Loss) of the Partnership for the period ending on such Settlement Date in accordance with Article V and (ii) credit the Withdrawn Partner’s GP-Related Capital Accounts with interest in accordance with Section 5.2. In making the foregoing calculations, the General Partner shall be entitled to establish such reserves (including reserves for taxes, bad debts, unrealized losses, actual or threatened litigation or any other expenses, contingencies or obligations) as it deems appropriate. Unless otherwise determined by the General Partner in a particular case, a Withdrawn Partner shall not be entitled to receive any GP-Related Unallocated Percentage in respect of the accounting period during which such Partner Withdraws from the Partnership (whether or not previously awarded or allocated) or any GP-Related Unallocated Percentage in respect of prior accounting periods that have not been paid or allocated (whether or not previously awarded) as of such Withdrawn Partner’s Withdrawal Date.

(d) From and after the Settlement Date of the Withdrawn Partner, the Withdrawn Partner’s GP-Related Profit Sharing Percentages shall, unless otherwise allocated by the General Partner pursuant to Section 5.3(a), be deemed to be GP-Related Unallocated Percentages (except for GP-Related Profit Sharing Percentages with respect to GP-Related Investments as provided in paragraph (f) below).

(e) (i) Upon the Withdrawal from the Partnership of a Partner with respect to such Partner’s GP-Related Partner Interest, such Withdrawn Partner thereafter shall not, except as expressly provided in this Section 6.5, have any rights of a Partner (including voting rights) with respect to such Partner’s GP-Related Partner Interest, and, except as expressly provided in this Section 6.5, such Withdrawn Partner shall not have any interest in the Partnership’s GP-Related Net Income (Loss), or in distributions related to such Partner’s GP-Related Partner Interest, GP-Related Investments or other assets related to such Partner’s GP-Related Partner Interest. If a Partner Withdraws from the Partnership with respect to such Partner’s GP-Related Partner Interest for any reason other than for Cause pursuant to Section 6.2, then the Withdrawn Partner shall be entitled to receive, at the time or times specified in Section 6.5(i) below, in satisfaction and discharge in full of the Withdrawn Partner’s GP-Related Partner Interest in the Partnership, (x) payment equal to the aggregate credit balance, if any, as of the Settlement Date of the Withdrawn Partner’s GP-Related Capital Accounts, (excluding any GP-Related Capital Account or portion thereof attributable to any GP-Related Investment) and (y) the Withdrawn Partner’s percentage interest attributable to each GP-Related Investment in which the Withdrawn Partner has an interest as of the Settlement Date as provided in paragraph (f) below (which shall be settled in accordance with paragraph (f) below), subject to all the terms and conditions of paragraphs (a)-(r) of this Section 6.5. If the amount determined pursuant to clause (x) above is an aggregate negative balance, the Withdrawn Partner shall pay the amount thereof to the Partnership upon demand by the General Partner on or after the date of the statement referred to in Section 6.5(i) below; provided, that if the Withdrawn Partner was solely a Special Partner on his or her Withdrawal Date, such payment shall be required only to the extent of any amounts payable to such Withdrawn Partner pursuant to this Section 6.5. Any aggregate negative balance in the GP-Related Capital Accounts of a Withdrawn Partner who was solely a Special Partner, upon the settlement of such Withdrawn Partner’s GP-Related Partner Interest in the Partnership pursuant to this Section 6.5, shall be allocated among the other Partners’ GP-Related Capital Accounts in accordance with their respective GP-Related Profit Sharing Percentages in the categories of GP-Related Net Income (Loss) giving rise to such negative balance as determined by the General Partner as of such Withdrawn Partner’s Settlement Date. In the settlement of any Withdrawn Partner’s GP-Related Partner Interest in the Partnership, no value shall be ascribed to goodwill, the Partnership name or the anticipation of any value the Partnership or any successor thereto might have in the event the Partnership or any interest therein were to be sold in whole or in part.

(ii) Notwithstanding clause (i) of this Section 6.5(e), in the case of a Partner whose Withdrawal with respect to such Partner’s GP-Related Partner Interest resulted from such Partner’s death or Incompetence, such Partner’s estate or legal representative, as the case may be, may elect, at the time described below, to receive a Nonvoting Special Partner GP-Related Partner Interest and retain such Partner’s GP-Related Profit Sharing Percentage in all (but not less than all) illiquid investments of the Partnership in lieu of a cash payment (or Investor Note) in settlement of that portion of the Withdrawn Partner’s GP-Related Partner Interest. The election referred to above shall be made within 60 days after the Withdrawn Partner’s Settlement Date, based on a statement of the settlement of such Withdrawn Partner’s GP-Related Partner Interest in the Partnership pursuant to this Section 6.5.

(f) For purposes of clause (y) of paragraph (e)(i) above, a Withdrawn Partner’s “percentage interest” means his or her GP-Related Profit Sharing Percentage as of the Settlement Date in the relevant GP-Related Investment. The Withdrawn Partner shall retain his or her percentage interest in such GP-Related Investment and shall retain his or her GP-Related Capital Account or portion thereof attributable to such GP-Related Investment, in which case such Withdrawn Partner (a “Retaining Withdrawn Partner”) shall become and remain a Special Partner for such purpose (and, if the General Partner so designates, such Special Partner shall be a Nonvoting Special Partner). The GP-Related Partner Interest of a Retaining Withdrawn Partner pursuant to this paragraph (f) shall be subject to the terms and conditions applicable to GP-Related Partner Interests of any kind hereunder and such other terms and conditions as are established by the General Partner. At the option of the General Partner in its sole discretion, the General Partner and the Retaining Withdrawn Partner may agree to have the Partnership acquire such GP-Related Partner Interest without the approval of the other Partners; provided, that the General Partner shall reflect in the books and records of the Partnership the terms of any acquisition pursuant to this sentence.

(g) The General Partner may elect, in lieu of payment in cash of any amount payable to a Withdrawn Partner pursuant to paragraph (e) above, to (i) have the Partnership issue to the Withdrawn Partner a subordinated promissory note and/or to (ii) distribute in kind to the Withdrawn Partner such Withdrawn Partner’s pro rata share (as determined by the General Partner) of any securities or other investments of the Partnership in relation to such Partner’s GP-Related Partner Interest. If any securities or other investments are distributed in kind to a Withdrawn Partner under this paragraph (g), the amount described in clause (x) of paragraph (e)(i) shall be reduced by the value of such distribution as valued on the latest balance sheet of the Partnership in accordance with generally accepted accounting principles or, if not appearing on such balance sheet, as reasonably determined by the General Partner.

(h) [Intentionally omitted].

(i) Within 120 days after each Settlement Date, the General Partner shall submit to the Withdrawn Partner a statement of the settlement of such Withdrawn Partner’s GP-Related Partner Interest in the Partnership pursuant to this Section 6.5 together with any cash payment, subordinated promissory note and in kind distributions to be made to such Partner as shall be determined by the General Partner. The General Partner shall submit to the Withdrawn Partner supplemental statements with respect to additional amounts payable to or by the Withdrawn Partner in respect of the settlement of his or her GP-Related Partner Interest in the Partnership (e.g., payments in respect of GP-Related Investments pursuant to paragraph (f) above or adjustments to reserves pursuant to paragraph (j) below) promptly after such amounts are determined by the General Partner. To the fullest extent permitted by law, such statements and

the valuations on which they are based shall be accepted by the Withdrawn Partner without examination of the accounting books and records of the Partnership or other inquiry. Any amounts payable by the Partnership to a Withdrawn Partner pursuant to this Section 6.5 shall be subordinate in right of payment and subject to the prior payment or provision for payment in full of claims of all present or future creditors of the Partnership or any successor thereto arising out of matters occurring prior to the applicable date of payment or distribution; provided, that such Withdrawn Partner shall otherwise rank pari passu in right of payment (x) with all persons who become Withdrawn Partners and whose Withdrawal Date is within one year before the Withdrawal Date of the Withdrawn Partner in question and (y) with all persons who become Withdrawn Partners and whose Withdrawal Date is within one year after the Withdrawal Date of the Withdrawn Partner in question.

(j) If the aggregate reserves established by the General Partner as of the Settlement Date in making the foregoing calculations should prove, in the determination of the General Partner, to be excessive or inadequate, the General Partner may elect, but shall not be obligated, to pay the Withdrawn Partner or his or her estate such excess, or to charge the Withdrawn Partner or his or her estate such deficiency, as the case may be.

(k) Any amounts owed by the Withdrawn Partner to the Partnership at any time on or after the Settlement Date (e.g., outstanding Partnership loans or advances to such Withdrawn Partner) shall be offset against any amounts payable or distributable by the Partnership to the Withdrawn Partner at any time on or after the Settlement Date or shall be paid by the Withdrawn Partner to the Partnership, in each case as determined by the General Partner. All cash amounts payable by a Withdrawn Partner to the Partnership under this Section 6.5 shall bear interest from the due date to the date of payment at a floating rate equal to the lesser of (x) the Prime Rate or (y) the maximum rate of interest permitted by applicable law. The “due date” of amounts payable by a Withdrawn Partner pursuant to Section 6.5(i) above shall be 120 days after a Withdrawn Partner’s Settlement Date. The “due date” of amounts payable to or by a Withdrawn Partner in respect of GP-Related Investments for which the Withdrawn Partner has retained a percentage interest in accordance with paragraph (f) above shall be 120 days after realization with respect to such GP-Related Investment. The “due date” of any other amounts payable by a Withdrawn Partner shall be 60 days after the date such amounts are determined to be payable.

(l) At the time of the settlement of any Withdrawn Partner’s GP-Related Partner Interest in the Partnership pursuant to this Section 6.5, the General Partner may, to the fullest extent permitted by applicable law, impose any restrictions it deems appropriate on the assignment, pledge, grant of a security interest, encumbrance or other transfer by such Withdrawn Partner of any interest in any GP-Related Investment retained by such Withdrawn Partner, any securities or other investments distributed in kind to such Withdrawn Partner or such Withdrawn Partner’s right to any payment from the Partnership.

(m) If a Partner is required to Withdraw from the Partnership with respect to such Partner’s GP-Related Partner Interest for Cause pursuant to Section 6.2(d), then his or her GP-Related Partner Interest shall be settled in accordance with paragraphs (a)-(r) of this Section 6.5; provided, that the General Partner may elect (but shall not be required) to apply any or all the following terms and conditions to such settlement:

(i) In settling the Withdrawn Partner’s interest in any GP-Related Investment in which he or she has an interest as of his or her Settlement Date, the General Partner may elect to (A) determine the GP-Related Unrealized Net Income (Loss) attributable to each such GP-Related Investment as of the Settlement Date and allocate to the appropriate GP-Related Capital Account of the Withdrawn Partner his or her allocable share of such GP-Related Unrealized Net Income (Loss) for purposes of calculating the aggregate balance of such Withdrawn Partner’s GP-Related Capital Account pursuant to clause (x) of paragraph (e)(i) above, (B) credit or debit, as applicable, the Withdrawn Partner with the balance of his or her GP-Related Capital Account or portion thereof attributable to each such GP-Related Investment as of his or her Settlement Date without giving effect to the GP-Related Unrealized Net Income (Loss) from such GP-Related Investment as of his or her Settlement Date, which shall be forfeited by the Withdrawn Partner or (C) apply the provisions of paragraph (f) above; provided, that the maximum amount of GP-Related Net Income (Loss) allocable to such Withdrawn Partner with respect to any GP-Related Investment shall equal such Partner’s percentage interest of the GP-Related Unrealized Net Income, if any, attributable to such GP-Related Investment as of the Settlement Date (the balance of such GP-Related Net Income (Loss), if any, shall be allocated as determined by the General Partner). The Withdrawn Partner shall not have any continuing interest in any GP-Related Investment to the extent an election is made pursuant to (A) or (B) above.

(ii) Any amounts payable by the Partnership to the Withdrawn Partner pursuant to this Section 6.5 shall be subordinate in right of payment and subject to the prior payment in full of claims of all present or future creditors of the Partnership or any successor thereto arising out of matters occurring prior to or on or after the applicable date of payment or distribution.

(n) The payments to a Withdrawn Partner pursuant to this Section 6.5 may be conditioned on the compliance by such Withdrawn Partner with any lawful and reasonable (under the circumstances) restrictions against engaging or investing in a business competitive with that of the Partnership or any of its subsidiaries and Affiliates for a period not exceeding two years determined by the General Partner. Upon written notice to the General Partner, any Withdrawn Partner who is subject to noncompetition restrictions established by the General Partner pursuant to this paragraph (n) may elect to forfeit the principal amount payable in the final installment of his or her subordinated promissory note, together with interest to be accrued on such installment after the date of forfeiture, in lieu of being bound by such restrictions.

(o) In addition to the foregoing, the General Partner shall have the right to pay a Withdrawn Partner (other than the General Partner) a discretionary additional payment in an amount and based upon such circumstances and conditions as it determines to be relevant.

(p) The provisions of this Section 6.5 shall apply to any Investor Special Partner relating to a Limited Partner or Special Partner and to any transferee of any GP-Related Partner Interest of such Partner pursuant to Section 6.3 if such Partner Withdraws from the Partnership.

(q) (i) The Partnership will assist a Withdrawn Partner or his or her estate or guardian, as the case may be, in the settlement of the Withdrawn Partner’s GP-Related Partner Interest in the Partnership. Third party costs incurred by the Partnership in providing this assistance will be borne by the Withdrawn Partner or his or her estate.

(ii) The General Partner may reasonably determine in good faith to retain outside professionals to provide the assistance to Withdrawn Partners or their estates or guardians, as referred to above. In such instances, the General Partner will obtain the prior approval of a Withdrawn Partner or his or her estate or guardian, as the case may be, prior to engaging such professionals. If the Withdrawn Partner (or his or her estate or guardian) declines to incur such costs, the General Partner will provide such reasonable assistance as and when it can so as not to interfere with the Partnership’s day-to-day operating, financial, tax and other related responsibilities to the Partnership and the Partners.

(r) Each Partner (other than the General Partner) hereby irrevocably appoints the General Partner as such Partner’s true and lawful agent, representative and attorney-in-fact, each acting alone, in such Partner’s name, place and stead, to make, execute, sign and file, on behalf of such Partner, any and all agreements, instruments, consents, ratifications, documents and certificates which the General Partner deems necessary or advisable in connection with any transaction or matter contemplated by or provided for in this Section 6.5, including, without limitation, the performance of any obligation of such Partner or the Partnership or the exercise of any right of such Partner or the Partnership. Such power of attorney is coupled with an interest and shall survive and continue in full force and effect notwithstanding the Withdrawal from the Partnership of any Partner for any reason and shall not be affected by the death, disability or incapacity of such Partner.

Section 6.6. Dissolution of the Partnership. The General Partner may dissolve the Partnership prior to the expiration of its term at any time on not less than 60 days’ notice of the dissolution date given to the other Partners. Upon the dissolution of the Partnership, the Partners’ respective interests in the Partnership shall be valued and settled in accordance with the procedures set forth in Section 6.5.

Section 6.7. Certain Tax Matters. (a) The General Partner shall determine all matters concerning allocations for tax purposes not expressly provided for herein in its sole discretion.

(b) The General Partner shall cause to be prepared all federal, state and local tax returns of the Partnership for each year for which such returns are required to be filed and, after approval of such returns by the General Partner, shall cause such returns to be timely filed. The General Partner shall determine the appropriate treatment of each item of income, gain, loss, deduction and credit of the Partnership and the accounting methods and conventions under the tax laws of the United States, the several States and other relevant jurisdictions as to the treatment of any such item or any other method or procedure related to the preparation of such tax returns. The General Partner may cause the Partnership to make or refrain from making any and all elections permitted by such tax laws. Each Partner agrees that he or she shall not, unless he or she provides prior notice of such action to the Partnership, (i) treat, on his or her individual

income tax returns, any item of income, gain, loss, deduction or credit relating to his or her interest in the Partnership in a manner inconsistent with the treatment of such item by the Partnership as reflected on the Form K-1 or other information statement furnished by the Partnership to such Partner for use in preparing his or her income tax returns or (ii) file any claim for refund relating to any such item based on, or which would result in, such inconsistent treatment. In respect of an income tax audit of any tax return of the Partnership, the filing of any amended return or claim for refund in connection with any item of income, gain, loss, deduction or credit reflected on any tax return of the Partnership, or any administrative or judicial proceedings arising out of or in connection with any such audit, amended return, claim for refund or denial of such claim, (A) the Tax Matters Partner (as defined below) shall be authorized to act for, and his or her decision shall be final and binding upon, the Partnership and all Partners except to the extent a Partner shall properly elect to be excluded from such proceeding pursuant to the Code, (B) all expenses incurred by the Tax Matters Partner in connection therewith (including, without limitation, attorneys’, accountants’ and other experts’ fees and disbursements) shall be expenses of the Partnership and (C) no Partner shall have the right to (1) participate in the audit of any Partnership tax return, (2) file any amended return or claim for refund in connection with any item of income, gain, loss, deduction or credit reflected on any tax return of the Partnership (unless he or she provides prior notice of such action to the Partnership as provided above), (3) participate in any administrative or judicial proceedings conducted by the Partnership or the Tax Matters Partner arising out of or in connection with any such audit, amended return, claim for refund or denial of such claim, or (4) appeal, challenge or otherwise protest any adverse findings in any such audit conducted by the Partnership or the Tax Matters Partner or with respect to any such amended return or claim for refund filed by the Partnership or the Tax Matters Partner or in any such administrative or judicial proceedings conducted by the Partnership or the Tax Matters Partner. The Partnership and each Partner hereby designate any Partner selected by the General Partner as the “partnership representative” (as defined under the Code) (the “Tax Matters Partner”). To the fullest extent permitted by applicable law, each Partner agrees to indemnify and hold harmless the Partnership and all other Partners from and against any and all liabilities, obligations, damages, deficiencies and expenses resulting from any breach or violation by such Partner of the provisions of this Section 6.7 and from all actions, suits, proceedings, demands, assessments, judgments, costs and expenses, including reasonable attorneys’ fees and disbursements, incident to any such breach or violation.

(c) Each individual Partner shall provide to the Partnership copies of each federal, state and local income tax return of such Partner (including any amendment thereof) within 30 days after filing such return.

(d) 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 on such amounts, on behalf of or with respect to any Partner, including pursuant to Section 6225 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 made on behalf of 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 upon

dissolution of the Partnership otherwise payable to such Partner. Whenever the General Partner selects option (ii) pursuant to the 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 (whether before or upon dissolution of the Partnership) unreduced by the amount of such Tax Advance. To the fullest extent permitted by law, each Partner hereby agrees to indemnify and hold harmless the Partnership and the other Partners from and against any liability (including, without limitation, any liability for taxes, penalties, additions to tax or interest) with respect to income attributable to or distributions or other payments to such Partner. The obligations of a Partner set forth in this Section 6.7(d) shall survive the Withdrawal of any Partner from the Partnership or any Transfer of a Partner’s interest.

Section 6.8. Special Basis Adjustments. In connection with any assignment or transfer of a Partnership interest permitted by the terms of this Agreement, the General Partner may cause the Partnership, on behalf of the Partners and at the time and in the manner provided in Treasury Regulations Section 1.754-1(b), to make an election to adjust the basis of the Partnership’s property in the manner provided in Sections 734(b) and 743(b) of the Code.

ARTICLE VII

CAPITAL COMMITMENT INTERESTS; CAPITAL CONTRIBUTIONS;

ALLOCATIONS; DISTRIBUTIONS

Section 7.1. Capital Commitment Interests, etc.

(a) (i) This Article VII and Article VIII hereof set forth certain terms and conditions with respect to the Capital Commitment Partner Interests and the Capital Commitment SP Infrastructure III Interest and matters related to the Capital Commitment Partner Interests and the Capital Commitment SP Infrastructure III Interest. Except as otherwise expressly provided in this Article VII or in Article VIII, the terms and provisions of this Article VII and Article VIII shall not apply to the GP-Related Partner Interests or the GP-Related SP Infrastructure III Interest.

(ii) Each Partner severally, agrees to make contributions of capital to the Partnership (“Capital Commitment-Related Capital Contributions”) as required to fund the Partnership’s capital contributions to SP Infrastructure III in respect of the Capital Commitment SP Infrastructure III Interest, if any, and the related Capital Commitment SP Infrastructure III Commitment, if any (including, without limitation, funding all or a portion of the Blackstone Capital Commitment). No Partner shall be obligated to make Capital Commitment-Related Capital Contributions to the Partnership in an amount in excess of such Partner’s Capital Commitment-Related Commitment. The Commitment Agreements and SMD Agreements, if any, of the Partners may include provisions with respect to the foregoing matters. It is understood that a Partner will not necessarily participate in each Capital Commitment Investment (which may include additional amounts invested in an existing Capital Commitment Investment) nor will a Partner necessarily have the same Capital Commitment Profit Sharing Percentage with respect to (i) the Partnership’s portion of the Blackstone Capital Commitment, or (ii) the making of each Capital Commitment Investment in which such Partner participates;

provided, that this in no way limits the terms of any Commitment Agreement or SMD Agreement. In addition, nothing contained herein shall be construed to give any Partner the right to obtain financing with respect to the purchase of any Capital Commitment Interest, and nothing contained herein shall limit or dictate the terms upon which the Partnership and its Affiliates may provide such financing. The acquisition of a Capital Commitment Interest by a Partner shall be evidenced by receipt by the Partnership of funds equal to such Partner’s Capital Commitment-Related Commitment then due with respect to such Capital Commitment Interest and such appropriate documentation as the General Partner may submit to the Partners from time to time.

(b) The Partnership or one of its Affiliates (in such capacity, the “Advancing Party”) may in its sole discretion advance to any Partner (including any additional Partner admitted to the Partnership pursuant to Section 6.1 but excluding any Partners that are also executive officers of Blackstone) all or any portion of the Capital Commitment-Related Capital Contributions due to the Partnership from such Partner with respect to any Capital Commitment Investment (“Firm Advances”). Each such Partner shall pay interest to the Advancing Party on each Firm Advance from the date of such Firm Advance until the repayment thereof by such Partner. Each Firm Advance shall be repayable in full, including accrued interest to the date of such repayment, upon prior written notice by the Advancing Party. The making and repayment of each Firm Advance shall be recorded in the books and records of the Partnership, and such recording shall be conclusive evidence of each such Firm Advance, binding on the Partner and the Advancing Party absent manifest error. Except as provided below, the interest rate applicable to a Firm Advance shall equal the cost of funds of the Advancing Party at the time of the making of such Firm Advance. The Advancing Party shall inform any Partner of such rate upon such Partner’s request; provided, that such interest rate shall not exceed the maximum interest rate allowable by applicable law; provided further, that amounts that are otherwise payable to such Partner pursuant to Section 7.4(a) shall be used to repay such Firm Advance (including interest thereon). The Advancing Party may, in its sole discretion, change the terms of Firm Advances (including the terms contained herein) and/or discontinue the making of Firm Advances; provided, that (i) the Advancing Party shall notify the relevant Partners of any material changes to such terms and (ii) the interest rate applicable to such Firm Advances and overdue amounts thereon shall not exceed the maximum interest rate allowable by applicable law.

Section 7.2. Capital Commitment Capital Accounts.

(a) There shall be established for each Partner in the books of the Partnership as of the date of formation of the Partnership, or such later date on which such Partner is admitted to the Partnership, and on each such other date as such Partner first acquires a Capital Commitment Interest in a particular Capital Commitment Investment, a Capital Commitment Capital Account for each Capital Commitment Investment in which such Partner acquires a Capital Commitment Interest on such date. Each Capital Commitment-Related Capital Contribution of a Partner shall be credited to the appropriate Capital Commitment Capital Account of such Partner on the date such Capital Commitment-Related Capital Contribution is paid to the Partnership. Capital Commitment Capital Accounts shall be adjusted to reflect any transfer of a Partner’s interest in the Partnership related to his or her Capital Commitment Partner Interest as provided in this Agreement.

(b) A Partner shall not have any obligation to the Partnership or to any other Partner to restore any negative balance in the Capital Commitment Capital Account of such Partner. Until distribution of any such Partner’s interest in the Partnership with respect to a Capital Commitment Interest as a result of the disposition by the Partnership of the related Capital Commitment Investment and in whole upon the dissolution of the Partnership, neither such Partner’s Capital Commitment Capital Accounts nor any part thereof shall be subject to withdrawal or redemption except with the consent of the General Partner.

Section 7.3. Allocations.

(a) Capital Commitment Net Income (Loss) of the Partnership for each Capital Commitment Investment shall be allocated to the related Capital Commitment Capital Accounts of all the Partners (including the General Partner) participating in such Capital Commitment Investment in proportion to their respective Capital Commitment Profit Sharing Percentages for such Capital Commitment Investment. Capital Commitment Net Income (Loss) on any Unallocated Capital Commitment Interest shall be allocated to each Partner in the proportion which such Partner’s aggregate Capital Commitment Capital Accounts bear to the aggregate Capital Commitment Capital Accounts of all Partners; provided, that if any Partner makes the election provided for in Section 7.6, Capital Commitment Net Income (Loss) of the Partnership for each Capital Commitment Investment shall be allocated to the related Capital Commitment Capital Accounts of all the Partners participating in such Capital Commitment Investment who do not make such election in proportion to their respective Capital Commitment Profit Sharing Percentages for such Capital Commitment Investment.

(b) Any special costs relating to distributions pursuant to Section 7.6 or Section 7.7 shall be specially allocated to the electing Partner.

(c) 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 facts and circumstances as the General Partner deems reasonably necessary for this purpose.

Section 7.4. Distributions.

(a) Each Partner’s allocable portion of Capital Commitment Net Income received from his or her Capital Commitment Investments, distributions to such Partner that constitute returns of capital, and other Capital Commitment Net Income of the Partnership (including, without limitation, Capital Commitment Net Income attributable to Unallocated Capital Commitment Interests) during a Fiscal Year of the Partnership will be credited to payment of the Investor Notes to the extent required below as of the last day of such Fiscal Year (or on such earlier date as related distributions are made in the sole discretion of the General Partner) with any cash amount distributable to such Partner pursuant to clauses (ii) and (vii) below to be distributed within 45 days after the end of each Fiscal Year of the Partnership (or in each case on such earlier date as selected by the General Partner in its sole discretion) as follows (subject to Section 7.4(c) below):

(i) First, to the payment of interest then due on all Investor Notes (relating to Capital Commitment Investments or otherwise) of such Partner (to the extent Capital Commitment Net Income and distributions or payments from Other Sources do not equal or exceed all interest payments due, the selection of those of such Partner’s Investor Notes upon which interest is to be paid and the division of payments among such Investor Notes to be determined by the Lender or Guarantor);

(ii) Second, to distribution to the Partner of an amount equal to the U.S. federal, state and local income taxes on income of the Partnership allocated to such Partner for such year in respect of such Partner’s Capital Commitment Partner Interest (the aggregate amount of any such distribution shall be determined by the General Partner, subject to the limitation that the minimum aggregate amount of such distribution be the tax that would be payable if the taxable income of the Partnership related to all Partners’ Capital Commitment Partner Interests were all allocated to an individual subject to the then-prevailing maximum rate of U.S. federal, New York State and New York City taxes (including, without limitation, taxes imposed under Section 1411 of the Code), taking into account the character of such taxable income allocated by the Partnership and the limitations on deductibility of expenses and other items for U.S. federal income tax purposes); provided, that additional amounts shall be paid to the Partner pursuant to this clause (ii) to the extent that such amount reduces the amount otherwise distributable to the Partner pursuant to a comparable provision in any other BE Agreement and there are not sufficient amounts to fully satisfy such provision from the relevant partnership or other entity; provided further, that amounts paid pursuant to the provisions in such other BE Agreements comparable to the immediately preceding proviso shall reduce those amounts otherwise distributable to the Partner pursuant to provisions in such other BE Agreements that are comparable to this clause (ii);

(iii) Third, to the payment in full of the principal amount of the Investor Note financing (A) any Capital Commitment Investment disposed of during or prior to such Fiscal Year or (B) any BE Investments (other than Capital Commitment Investments) disposed of during or prior to such Fiscal Year, to the extent not repaid from Other Sources;

(iv) Fourth, to the return to such Partner of (A) all Capital Commitment-Related Capital Contributions made in respect of the Capital Commitment Interest to which any Capital Commitment Investment disposed of during or prior to such Fiscal Year relates or (B) all capital contributions made to any Blackstone Entity (other than the Partnership) in respect of interests therein relating to BE Investments (other than Capital Commitment Investments) disposed of during or prior to such Fiscal Year (including all principal paid on the related Investor Notes), to the extent not repaid from amounts of Other Sources (other than amounts of Capital Commitment Partner Carried Interest);

(v) Fifth, to the payment of principal (including any previously deferred amounts) then owing under all other Investor Notes of such Partner (including those unrelated to the Partnership), the selection of those of such Partner’s Investor Notes to be repaid and the division of payments among such Investor Notes to be determined by the Lender or Guarantor;

(vi) Sixth, up to 50% of any Capital Commitment Net Income remaining after application pursuant to clauses (i) through (v) above shall be applied pro rata to prepayment of principal of all remaining Investor Notes of such Partner (including those unrelated to the Partnership), the selection of those of such Partner’s Investor Notes to be repaid, the division of payments among such Investor Notes and the percentage of remaining Capital Commitment Net Income to be applied thereto to be determined by the Lender or Guarantor; and

(vii) Seventh, to such Partner to the extent of any amount of Capital Commitment Net Income remaining after making the distributions in clauses (i) through (vi) above, and such amount is not otherwise required to be applied to Investor Notes pursuant to the terms thereof.

To the extent there is a partial disposition of a Capital Commitment Investment or any other BE Investment, as applicable, the payments in clauses (iii) and (iv) above shall be based on that portion of the Capital Commitment Investment or other BE Investment, as applicable, disposed of, and the principal amount and related interest payments of such Investor Note shall be adjusted to reflect such partial payment so that there are equal payments over the remaining term of the related Investor Note. For a Partner who is no longer an employee or officer of Holdings or an Affiliate thereof, distributions shall be made pursuant to clauses (i) through (iii) above, and then, unless the Partnership or its Affiliate has exercised its rights pursuant to Section 8.1 hereof, any remaining income or other distribution in respect of such Partner’s Capital Commitment Partner Interest shall be applied to the prepayment of the outstanding Investor Notes of such Partner, until all such Partner’s Investor Notes have been repaid in full, with any such income or other distribution remaining thereafter distributed to such Partner.

Distributions of Capital Commitment Net Income may be made at any other time at the discretion of the General Partner. At the General Partner’s discretion, any amounts distributed to a Partner in respect of such Partner’s Capital Commitment Partner Interest will be net of any interest and principal payable on his or her Investor Notes for the full period in respect of which the distribution is made.

(b) [Intentionally omitted.]

(c) To the extent that the foregoing Partnership distributions and distributions and payments from Other Sources are insufficient to satisfy any principal and/or interest due on Investor Notes, and to the extent that the General Partner in its sole discretion elects to apply this paragraph (c) to any individual payments due, such unpaid interest will be added to the remaining principal amount of such Investor Notes and shall be payable on the next scheduled principal payment date (along with any deferred principal and any principal and interest due on such date); provided, that such deferral shall not apply to a Partner that is no longer an employee or officer of Holdings or its Affiliates. All unpaid interest on such Investor Notes shall accrue interest at the interest rate then in effect for such Investor Notes.

(d) [Intentionally omitted.]

(e) The Capital Commitment Capital Account of each Partner shall be reduced by the amount of any distribution to such Partner pursuant to Section 7.4(a).

(f) At any time that a sale, exchange, transfer or other disposition of a portion of a Capital Commitment Investment is being considered by the Partnership or SP Infrastructure III (a “Capital Commitment Disposable Investment”), at the election of the General Partner each Partner’s Capital Commitment Interest with respect to such Capital Commitment Investment shall be vertically divided into two separate Capital Commitment Interests, a Capital Commitment Interest attributable to the Capital Commitment Disposable Investment (a Partner’s “Capital Commitment Class B Interest”), and a Capital Commitment Interest attributable to such Capital Commitment Investment excluding the Capital Commitment Disposable Investment (a Partner’s “Capital Commitment Class A Interest”). Distributions (including those resulting from a direct or indirect sale, transfer, exchange or other disposition by the Partnership) relating to a Capital Commitment Disposable Investment shall be made only to holders of Capital Commitment Class B Interests with respect to such Capital Commitment Investment in accordance with their respective Capital Commitment Profit Sharing Percentages relating to such Capital Commitment Class B Interests, and distributions (including those resulting from the direct or indirect sale, transfer, exchange or other disposition by the Partnership) relating to a Capital Commitment Investment excluding such Capital Commitment Disposable Investment shall be made only to holders of Capital Commitment Class A Interests with respect to such Capital Commitment Investment in accordance with their respective Capital Commitment Profit Sharing Percentages relating to such Capital Commitment Class A Interests.

(g) (i) If the Partnership is obligated under the Giveback Provisions to contribute to SP Infrastructure III a Giveback Amount with respect to any Capital Commitment SP Infrastructure III Interest (the amount of any such obligation of the Partnership with respect to such a Giveback Amount being herein called a “Capital Commitment Giveback Amount”), the General Partner shall call for such amounts as are necessary to satisfy such obligation of the Partnership as determined by the General Partner, in which case each Partner and Withdrawn Partner shall contribute to the Partnership, in cash, when and as called by the General Partner, such an amount of prior distributions by the Partnership with respect to the Capital Commitment SP Infrastructure III Interest (the “Capital Commitment Recontribution Amount”) which equals such Partner’s pro rata share of prior distributions in connection with (a) the Capital Commitment SP Infrastructure III Investment giving rise to the Capital Commitment Giveback Amount, (b) if the amounts contributed pursuant to clause (a) above are insufficient to satisfy such Capital Commitment Giveback Amount, Capital Commitment SP Infrastructure III Investments other than the one giving rise to such obligation and (c) if the Capital Commitment Giveback Amount pursuant to an applicable SP Infrastructure III Agreement is unrelated to a specific Capital Commitment SP Infrastructure III Investment, all Capital Commitment SP Infrastructure III Investments. Each Partner shall promptly contribute to the Partnership upon notice thereof such Partner’s Capital Commitment Recontribution Amount. Prior to such time, the General Partner may, at the General Partner’s discretion (but shall be under no obligation to), provide notice that in the General Partner’s judgment, the potential obligations in respect of the Capital Commitment Giveback Amount will probably materialize (and an estimate of the aggregate amount of such obligations).

(ii) (A) In the event any Partner (a “Capital Commitment Defaulting Party”) fails to recontribute all or any portion of such Capital Commitment Defaulting Party’s Capital Commitment Recontribution Amount for any reason, the General Partner shall (i) use its reasonable efforts to collect any amounts from any such GP-Related Defaulting Party and (ii) require all other Partners and Withdrawn Partners to contribute, on a pro rata basis (based on each of their respective Capital Commitment Profit Sharing Percentages), such amounts as are necessary to fulfill the Capital Commitment Defaulting Party’s obligation to pay such Capital Commitment Defaulting Party’s Capital Commitment Recontribution Amount (a “Capital Commitment Deficiency Contribution”) if the General Partner determines in its good faith judgment that the Partnership will be unable to collect such amount in cash from such Capital Commitment Defaulting Party for payment of the Capital Commitment Giveback Amount at least 20 Business Days prior to the latest date that the Partnership is permitted to pay the Capital Commitment Giveback Amount; provided, that no Partner shall as a result of such Capital Commitment Deficiency Contribution be required to contribute an amount in excess of 150% of the amount of the Capital Commitment Recontribution Amount initially requested from such Partner’s in respect of such default. Thereafter, the General Partner shall determine in its good faith judgment that the Partnership should either (1) not attempt to collect such amount in light of the costs associated therewith, the likelihood of recovery and any other factors considered relevant in the good faith judgment of the General Partner or (2) pursue any and all remedies (at law or equity) available to the Partnership against the Capital Commitment Defaulting Party, the cost of which shall be a Partnership expense to the extent not ultimately reimbursed by the Capital Commitment Defaulting Party. It is agreed that the Partnership shall have the right (effective upon such Capital Commitment Defaulting Party becoming a Capital Commitment Defaulting Party) to set-off as appropriate and apply against such Capital Commitment Defaulting Party’s Capital Commitment Recontribution Amount any amounts otherwise payable to the Capital Commitment Defaulting Party by the Partnership or any Affiliate thereof. Each Partner hereby grants to the General Partner a security interest, effective upon such Partner becoming a Capital Commitment Defaulting Party, in all accounts receivable and other rights to receive payment from the Partnership or any Affiliate of the Partnership and agrees that, upon the effectiveness of such security interest, the General Partner may sell, collect or otherwise realize upon such collateral. In furtherance of the foregoing, each Partner hereby appoints the General Partner as its true and lawful attorney-in-fact with full irrevocable power and authority, in the name of such Partner or in the name of the Partnership, to take any actions which may be necessary to accomplish the intent of the immediately preceding sentence. The General Partner shall be entitled to collect interest on the Capital Commitment Recontribution Amount of a Capital Commitment Defaulting Party from the date such Capital Commitment Recontribution Amount was required to be contributed to the Partnership at a rate equal to the Default Interest Rate.

(B) Any Partner’s failure to make a Capital Commitment Deficiency Contribution shall cause such Partner to be a Capital Commitment Defaulting Party with respect to such amount.

(iii) A Partner’s obligation to make contributions to the Partnership under this Section 7.4(g) shall survive the termination of the Partnership.

Section 7.5. Valuations. Capital Commitment Investments shall be valued annually as of the end of each year (and at such other times as deemed appropriate by the General Partner) in accordance with the principles utilized by the Partnership (or any other Affiliate of the Partnership that is a general partner of SP Infrastructure III) in valuing investments of SP Infrastructure III or, in the case of investments not held by SP Infrastructure III, in the good faith judgment of the General Partner, subject in each case to the second proviso of the immediately succeeding sentence. The value of any Capital Commitment Interest as of any date (the “Capital Commitment Value”) shall be based on the value of the underlying Capital Commitment Investment as set forth above; provided, that the Capital Commitment Value may be determined as of an earlier date if determined appropriate by the General Partner in good faith; provided further, that such value may be adjusted by the General Partner to take into account factors relating solely to the value of a Capital Commitment Interest (as compared to the value of the underlying Capital Commitment Investment), such as restrictions on transferability, the lack of a market for such Capital Commitment Interest and lack of control of the underlying Capital Commitment Investment. To the full extent permitted by applicable law such valuations shall be final and binding on all Partners; provided further, that the immediately preceding proviso shall not apply to any Capital Commitment Interests held by a person who is or was at any time a direct member or partner of a General Partner of the Partnership.

Section 7.6. Disposition Election.

(a) At any time prior to the date of the Partnership’s execution of a definitive agreement to dispose of a Capital Commitment Investment, the General Partner may in its sole discretion permit a Partner to retain all or any portion of its pro rata share of such Capital Commitment Investment (as measured by such Partner’s Capital Commitment Profit Sharing Percentage in such Capital Commitment Investment). If the General Partner so permits, such Partner shall instruct the General Partner in writing prior to such date (i) not to dispose of all or any portion of such Partner’s pro rata share of such Capital Commitment Investment (the “Retained Portion”) and (ii) either to (A) distribute such Retained Portion to such Partner on the closing date of such disposition or (B) retain such Retained Portion in the Partnership on behalf of such Partner until such time as such Partner shall instruct the General Partner upon 5 days’ notice to distribute such Retained Portion to such Partner. Such Partner’s Capital Commitment Capital Account shall not be adjusted in any way to reflect the retention in the Partnership of such Retained Portion or the Partnership’s disposition of other Partners’ pro rata shares of such Capital Commitment Investment; provided, that such Partner’s Capital Commitment Capital Account shall be adjusted upon distribution of such Retained Portion to such Partner or upon distribution of proceeds with respect to a subsequent disposition thereof by the Partnership.

(b) No distribution of such Retained Portion shall occur unless any Investor Notes relating thereto shall have been paid in full prior to or simultaneously with such distribution.

Section 7.7. Capital Commitment Special Distribution Election.

(a) From time to time during the term of this Agreement, the General Partner may in its sole discretion, upon receipt of a written request from a Partner, distribute to such Partner any portion of its pro rata share of a Capital Commitment Investment (as measured by such Partner’s Capital Commitment Profit Sharing Percentage in such Capital Commitment Investment) (a “Capital Commitment Special Distribution”). Such Partner’s Capital Commitment Capital Account shall be adjusted upon distribution of such Capital Commitment Special Distribution.

(b) No Capital Commitment Special Distributions shall occur unless any Investor Notes relating thereto shall have been paid in full prior to or simultaneously with such Capital Commitment Special Distribution.

ARTICLE VIII

WITHDRAWAL; ADMISSION OF NEW PARTNERS

Section 8.1. Partner Withdrawal; Repurchase of Capital Commitment Interests.

(a) Capital Commitment Interests (or a portion thereof) that were financed by Investor Notes will be treated as Non-Contingent for purposes hereof based upon the proportion of (a) the sum of Capital Commitment-Related Capital Contributions not financed by an Investor Note with respect to each Capital Commitment Interest and principal payments on the related Investor Note to (b) the sum of the Capital Commitment-Related Capital Contributions not financed by an Investor Note with respect to such Capital Commitment Interest, the original principal amount of such Investor Note and all deferred amounts of interest which from time to time comprise part of the principal amount of the Investor Note. A Partner may prepay a portion of any outstanding principal on the Investor Notes; provided, that in the event that a Partner prepays all or any portion of the principal amount of the Investor Notes within nine months prior to the date on which such Partner is no longer an employee or officer of Holdings or an Affiliate thereof, the Partnership (or its designee) shall have the right, in its sole discretion, to purchase the Capital Commitment Interest that became Non-Contingent as a result of such prepayment; provided further, that the purchase price for such Capital Commitment Interest shall be determined in accordance with the determination of the purchase price of a Partner’s Contingent Capital Commitment Interests as set forth in paragraph (b) below. Prepayments made by a Partner shall apply pro rata against all of such Partner’s Investor Notes; provided, that such Partner may request that such prepayments be applied only to Investor Notes related to BE Investments that are related to one or more Blackstone Entities specified by such Partner. Except as expressly provided herein, Capital Commitment Interests that were not financed in any respect with Investor Notes shall be treated as Non-Contingent Capital Commitment Interests.

(b) (i) Upon a Partner ceasing to be an officer or employee of the Partnership or any of its Affiliates, other than as a result of such Partner dying or suffering a Total Disability, such Partner and the Partnership or any other person designated by the General Partner shall each have the right (exercisable by the Withdrawn Partner within 30 days and by the Partnership or its designee(s) within 45 days after such Partner’s ceasing to be such an officer or employee) or any time thereafter, upon 30 days’ notice, but not the obligation, to require the Partnership (subject to the prior consent of the General Partner, such consent not to be unreasonably withheld or delayed), subject to the Partnership Act, to buy (in the case of exercise of such right by such Withdrawn Partner) or the Withdrawn Partner to sell (in the case of exercise of such right by the Partnership or its designee(s)) all (but not less than all) such Withdrawn Partner’s Contingent Capital Commitment Interests.

(ii) The purchase price for each such Contingent Capital Commitment Interest shall be an amount equal to (A) the outstanding principal amount of the related Investor Note plus accrued interest thereon to the date of purchase (such portion of the purchase price to be paid in cash) and (B) an additional amount (the “Adjustment Amount”) equal to (x) all interest paid by the Partner on the portion of the principal amount of such Investor Note(s) relating to the portion of the related Capital Commitment Interest remaining Contingent and to be repurchased, plus (y) all Capital Commitment Net Losses allocated to the Withdrawn Partner on such Contingent portion of such Capital Commitment Interest, minus (z) all Capital Commitment Net Income allocated to the Withdrawn Partner on the Contingent portion of such Capital Commitment Interest; provided, that, if the Withdrawn Partner was terminated from employment or his or her position as an officer for Cause, all amounts referred to in clause (x) or (y) of the Adjustment Amount, in the General Partner’s sole discretion, may be deemed to equal zero. The Adjustment Amount shall, if positive, be payable by the holders of the purchased Capital Commitment Interests to the Withdrawn Partner from the next Capital Commitment Net Income received by such holders on the Contingent portion of such Withdrawn Partner’s Capital Commitment Interests at the time such Capital Commitment Net Income is received. If the Adjustment Amount is negative, it shall be payable to the holders of the purchased Capital Commitment Interest by the Withdrawn Partner (A) from the next Capital Commitment Net Income on the Non-Contingent portion of the Withdrawn Partner’s Capital Commitment Interests at the time such Capital Commitment Net Income is received by the Withdrawn Partner, or (B) if the Partnership or its designee(s) elect to purchase such Withdrawn Partner’s Non-Contingent Capital Commitment Interests, in cash by the Withdrawn Partner at the time of such purchase; provided, that the Partnership and its Affiliates may offset any amounts otherwise owing to a Withdrawn Partner against any Adjustment Amount owed by such Withdrawn Partner. Until so paid, such remaining Adjustment Amount will not itself bear interest. At the time of such purchase of the Withdrawn Partner’s Contingent Capital Commitment Interests, his or her related Investor Note shall be payable in full.

(iii) Upon such Partner ceasing to be such an officer or employee, all Investor Notes shall become fully recourse to the Withdrawn Partner in his or her individual capacity (whether or not the Withdrawn Partner or the Partnership or its designee(s) exercises the right to require repurchase of the Withdrawn Partner’s Contingent Capital Commitment Interests).

(iv) If neither the Withdrawn Partner nor the Partnership nor its designee(s) exercises the right to require repurchase of such Contingent Capital Commitment Interests, then the Withdrawn Partner shall retain the Contingent portion of his or her Capital Commitment Interests and the Investor Notes shall remain outstanding, shall become fully recourse to the Withdrawn Partner in his or her individual capacity, shall be payable in accordance with their remaining original maturity schedules and shall be prepayable at any time by the Withdrawn Partner at his or her option, and the Partnership shall apply such prepayments against outstanding Investor Notes on a pro rata basis.

(v) To the extent that another Partner purchases a portion of a Capital Commitment Interest of a Withdrawn Partner, the purchasing Partner’s Capital Commitment Capital Account and Capital Commitment Profit Sharing Percentage for such Capital Commitment Investment shall be correspondingly increased.

(c) Upon the occurrence of a Final Event with respect to any Partner, such Partner shall thereupon cease to be a Partner with respect to such Partner’s Capital Commitment Partner Interest. If such a Final Event shall occur, no Successor in Interest to any such Partner shall for any purpose hereof become or be deemed to become a Partner. The sole right, as against the Partnership and the remaining Partners, acquired hereunder by, or resulting hereunder to, a Successor in Interest to any Partner shall be to receive any distributions and allocations with respect to such Partner’s Capital Commitment Partner Interest pursuant to Article VII and this Article VIII (subject to the right of the Partnership to purchase the Capital Commitment Interests of such former Partner pursuant to Section 8.1(b) or Section 8.1(d)), to the extent, at the time, in the manner and in the amount otherwise payable to such Partner had such a Final Event not occurred, and no other right shall be acquired hereunder by, or shall result hereunder to, a Successor in Interest to such Partner, whether by operation of law or otherwise and the Partnership shall be entitled to treat any Successor in Interest to such Partner as the only person entitled to receive distributions and allocations hereunder. Until distribution of any such Partner’s interest in the Partnership upon the dissolution of the Partnership as provided in Section 9.2, neither his or her Capital Commitment Capital Accounts nor any part thereof shall be subject to withdrawal or redemption without the consent of the General Partner. The General Partner shall be entitled to treat any Successor in Interest to such Partner as the only person entitled to receive distributions and allocations hereunder with respect to such Partner’s Capital Commitment Partner Interest.

(d) If a Partner dies or suffers a Total Disability, all Contingent Capital Commitment Interests of such Partner shall be purchased by the Partnership or its designee (within 30 days of the first date on which the Partnership knows or has reason to know of such Partner’s death or Total Disability) (and the purchase price for such Contingent Capital Commitment Interests shall be determined in accordance with Section 8.1(b) (except that any Adjustment Amount shall be payable by or to such Partner’s estate, personal representative or other Successor in Interest, in cash)), and any Investor Notes financing such Contingent Capital Commitment Interests shall thereupon be prepaid as provided in Section 8.1(b). Upon such Partner’s death or Total Disability, any Investor Note(s) financing such Contingent Capital Commitment Interests shall become fully recourse. In addition, in the case of the death or Total Disability of a Partner, if the estate, personal representative or other Successor in Interest of such Partner, so requests in writing within 180 days after the Partner’s death or ceasing to be an employee or member (directly or indirectly) of the Partnership or any of its Affiliates by reason of Total Disability (such requests shall not exceed one per calendar year), the Partnership or its designee may but is not obligated to purchase for cash all (but not less than all) Non-Contingent Capital Commitment Interests of such Partner as of the last day of the Partnership’s then current Fiscal Year at a price equal to the Capital Commitment Value thereof as of the most recent valuation prior to the date of purchase. Each Partner shall be required to include appropriate

provisions in his or her will to reflect such provisions of this Agreement. In addition, the Partnership may, in the sole discretion of the General Partner, upon notice to the estate, personal representative or other Successor in Interest of such Partner, within 30 days of the first date on which the General Partner knows or has reason to know of such Partner’s death or Total Disability, determine either (i) to distribute Securities or other property to the estate, personal representative or other Successor in Interest, in exchange for such Non-Contingent Capital Commitment Interests as provided in Section 8.1(e) or (ii) to require sale of such Non-Contingent Capital Commitment Interests to the Partnership or its designee as of the last day of any Fiscal Year of the Partnership (or earlier period, as determined by the General Partner in its sole discretion) for an amount in cash equal to the Capital Commitment Value thereof.

(e) In lieu of retaining a Withdrawn Partner as a Partner with respect to any Non-Contingent Capital Commitment Interests, the General Partner may, in its sole discretion, by notice to such Withdrawn Partner within 45 days of his or her ceasing to be an employee or officer of the Partnership or any of its Affiliates, or at any time thereafter, upon 30 days written notice, determine (1) to distribute to such Withdrawn Partner the pro rata portion of the Securities or other property underlying such Withdrawn Partner’s Non-Contingent Capital Commitment Interests, subject to any restrictions on distributions associated with the Securities or other property, in satisfaction of his or her Non-Contingent Capital Commitment Interests in the Partnership or (2) to cause, as of the last day of any Fiscal Year of the Partnership (or earlier period, as determined by the General Partner in its sole discretion), the Partnership or another person designated by the General Partner (who may be itself another Partner or another Affiliate of the Partnership) to purchase all (but not less than all) of such Withdrawn Partner’s Non-Contingent Capital Commitment Interests for a price equal to the Capital Commitment Value thereof (determined in good faith by the General Partner as of the most recent valuation prior to the date of purchase). The General Partner shall condition any distribution or purchase of voting Securities pursuant to paragraph (d) above or this paragraph (e) upon the Withdrawn Partner’s execution and delivery to the Partnership of an appropriate irrevocable proxy, in favor of the General Partner or its nominee, relating to such Securities.

(f) The Partnership may subsequently transfer any Unallocated Capital Commitment Interest or portion thereof which is purchased by it as described above to any other person approved by the General Partner. In connection with such purchase or transfer or the purchase of a Capital Commitment Interest or portion thereof by the General Partner’s designee(s), Holdings may loan all or a portion of the purchase price of the transferred or purchased Capital Commitment Interest to the Partnership, the transferee or the designee-purchaser(s), as applicable (excluding any of the foregoing who is an executive officer of The Blackstone Group Inc. or any Affiliate thereof). To the extent that a Withdrawn Partner’s Capital Commitment Interests (or portions thereof) are repurchased by the Partnership and not transferred to or purchased by another person, all or any portion of such repurchased Capital Commitment Interests may, in the sole discretion of the General Partner, (i) be allocated to each Partner already participating in the Capital Commitment Investment to which the repurchased Capital Commitment Interest relates, (ii) be allocated to each Partner in the Partnership, whether or not already participating in such Capital Commitment Investment, and/or (iii) continue to be held by the Partnership itself as an unallocated Capital Commitment Investment (such Capital Commitment Interests being herein called “Unallocated Capital Commitment Interests”). To the extent that a Capital Commitment Interest is allocated to Partners as provided in clause (i) and/or

(ii) above, any indebtedness incurred by the Partnership to finance such repurchase shall also be allocated to such Partners. All such Capital Commitment Interests allocated to Partners shall be deemed to be Contingent and shall become Non-Contingent as and to the extent that the principal amount of such related indebtedness is repaid. The Partners receiving such allocations shall be responsible for such related indebtedness only on a nonrecourse basis to the extent appropriate as provided in this Agreement, except as otherwise provided in this Section 8.1 and except as such Partners and the General Partner shall otherwise agree; provided, that such indebtedness shall become fully recourse to the extent and at the time provided in this Section 8.1. If the indebtedness financing such repurchased interests is not to be non-recourse or so limited, the Partnership may require an assumption by the Partners of such indebtedness on the terms thereof as a precondition to allocation of the related Capital Commitment Interests to such Partners; provided, that a Partner shall not, except as set forth in his or her Investor Note(s), be obligated to accept any obligation that is personally recourse (except as provided in this Section 8.1), unless his or her prior consent is obtained. So long as the Partnership itself retains the Unallocated Capital Commitment Interests pursuant to clause (iii) above, such Unallocated Capital Commitment Interests shall belong to the Partnership and any indebtedness financing the Unallocated Capital Commitment Interests shall be an obligation of the Partnership to which all income of the Partnership is subject except as otherwise agreed by the lender of such indebtedness. Any Capital Commitment Net Income (Loss) on an Unallocated Capital Commitment Interest shall be allocated to each Partner in the proportion his or her aggregate Capital Commitment Capital Accounts bear to the aggregate Capital Commitment Capital Accounts of all Partners; debt service on such related financing will be an expense of the Partnership allocable to all Partners in such proportions.

(g) If a Partner is required to Withdraw from the Partnership with respect to such Partner’s Capital Commitment Partner Interest for Cause, then his or her Capital Commitment Interest shall be settled in accordance with paragraphs (a)-(f) and (j) of this Section 8.1; provided, that if such Partner was not at any time a direct partner of a General Partner of the Partnership, the General Partner may elect (but shall not be required) to apply any or all the following terms and conditions to such settlement:

(i) purchase for cash all of such Withdrawn Partner’s Non-Contingent Capital Commitment Interests. The purchase price for each such Non-Contingent Capital Commitment Interest shall be the lower of (A) the original cost of such Non-Contingent Capital Commitment Interest or (B) an amount equal to the Capital Commitment Value thereof (determined as of the most recent valuation prior to the date of the purchase of such Non-Contingent Capital Commitment Interest);

(ii) allow the Withdrawn Partner to retain such Non-Contingent Capital Commitment Interests; provided, that the maximum amount of Capital Commitment Net Income allocable to such Withdrawn Partner with respect to any Capital Commitment Investment shall equal the amount of Capital Commitment Net Income that would have been allocated to such Withdrawn Partner if such Capital Commitment Investment had been sold as of the Settlement Date at the then prevailing Capital Commitment Value thereof; or (iii) in lieu of cash, purchase such Non-Contingent Capital Commitment Interests by providing the Withdrawn Partner with a promissory note in the amount determined in (i) above. Such promissory note shall have a maximum term of ten (10) years with interest at the Federal Funds Rate.

(h) The Partnership will assist a Withdrawn Partner or his or her estate or guardian, as the case may be, in the settlement of the Withdrawn Partner’s Capital Commitment Partner Interest in the Partnership. Third party costs incurred by the Partnership in providing this assistance will be borne by the Withdrawn Partner or his or her estate.

(i) The General Partner may reasonably determine in good faith to retain outside professionals to provide the assistance to Withdrawn Partners or their estates or guardians, as referred to above. In such instances, the General Partner will obtain the prior approval of a Withdrawn Partner or his or her estate or guardian, as the case may be, prior to engaging such professionals. If the Withdrawn Partner (or his or her estate or guardian) declines to incur such costs, the General Partner will provide such reasonable assistance as and when it can so as not to interfere with the Partnership’s day-to-day operating, financial, tax and other related responsibilities to the Partnership and the Partners.

(j) Each Partner hereby irrevocably appoints the General Partner as such Partner’s true and lawful agent, representative and attorney-in-fact, each acting alone, in such Partner’s name, place and stead, to make, execute, sign and file, on behalf of such Partner, any and all agreements, instruments, consents, ratifications, documents and certificates which such General Partner deems necessary or advisable in connection with any transaction or matter contemplated by or provided for in this Section 8.1, including, without limitation, the performance of any obligation of such Partner or the Partnership or the exercise of any right of such Partner or the Partnership. Such power of attorney is coupled with an interest and shall survive and continue in full force and effect notwithstanding the Withdrawal from the Partnership of any Partner for any reason and shall not be affected by the death, disability or incapacity of such Partner.

Section 8.2. Transfer of Partner’s Capital Commitment Interest. Except as otherwise agreed by the General Partner, no Partner or former Partner shall have the right to sell, assign, mortgage, pledge, grant a security interest over, or otherwise dispose of or transfer (“Transfer”) all or part of any such Partner’s Capital Commitment Partner Interest in the Partnership; provided, that this Section 8.2 shall in no way impair (i) Transfers as permitted in Section 8.1 above, in the case of the purchase of a Withdrawn Partner’s or Deceased or Totally Disabled Partner’s Capital Commitment Interests, (ii) with the prior written consent of the General Partner, which shall not be unreasonably withheld, Transfers by a Partner to another Partner of Non-Contingent Capital Commitment Interests, (iii) Transfers with the prior written consent of the General Partner (which consent may be granted or withheld in its sole discretion without giving any reason therefor) and (iv) with the prior written consent of the General Partner, which shall not be unreasonably withheld, Transfers of up to 25% of a Limited Partner’s Capital Commitment Partner Interest to an Estate Planning Vehicle (it being understood that it shall not be unreasonable for the General Partner to condition any Transfer of an Interest pursuant to this clause (iv) on the satisfaction of certain conditions and/or requirements imposed by the General Partner in connection with any such Transfer, including, for example, a requirement that any transferee of an Interest hold such Interest as a passive, non-voting interest in the Partnership). The General Partner shall designate that each Estate Planning Vehicle shall not have voting

rights (any such Partner being called a “Nonvoting Partner”). Such Partner shall be jointly and severally liable for all obligations of both such Partner and such Nonvoting Partner with respect to the interest transferred (including the obligation to make additional Capital Commitment-Related Capital Contributions). The General Partner may at its sole option exercisable at any time require such Estate Planning Vehicle to Withdraw from the Partnership on the terms of Section 8.1 and Article VI. No person acquiring an interest in the Partnership pursuant to this Section 8.2 shall become a Partner of the Partnership, or acquire such Partner’s right to participate in the affairs of the Partnership, unless such person shall be admitted as a Partner pursuant to Section 6.1. A Partner shall not cease to be a Partner of the Partnership upon the collateral assignment of, or the pledging or granting of a security interest in, its entire Interest in the Partnership in accordance with the provisions of this Agreement.

Section 8.3. Compliance with Law. Notwithstanding any provision hereof to the contrary, no sale or Transfer of a Capital Commitment Interest in the Partnership may be made except in compliance with all U.S. federal, state and other applicable laws, including U.S. federal and state securities laws.

ARTICLE IX

DISSOLUTION

Section 9.1. Dissolution. The Partnership shall be dissolved and subsequently terminated:

(a) pursuant to Section 6.6; or

(b) upon the expiration of the term of the Partnership.

Section 9.2. Final Distribution. Upon the dissolution of the Partnership, and following the payment of creditors of the Partnership and the making of provisions for the payment of any contingent, conditional or unmatured claims known to the Partnership as required under the Partnership Act:

(a) The Partners’ respective interests in the Partnership shall be valued and settled in accordance with the procedures set forth in Section 6.5 which provide for allocations to the GP-Related Capital Accounts of the Partners and distributions in accordance with the GP-Related Capital Account balances of the Partners; and

(b) With respect to each Partner’s Capital Commitment Partner Interest, an amount shall be paid to such Partner in cash or Securities in an amount equal to such Partner’s respective Capital Commitment Liquidating Share for each Capital Commitment Investment; provided, that if the remaining assets relating to any Capital Commitment Investment shall not be equal to or exceed the aggregate Capital Commitment Liquidating Shares for such Capital Commitment Investment, to each Partner in proportion to its Capital Commitment Liquidating Share for such Capital Commitment Investment; and the remaining assets of the Partnership related to the Partners’ Capital Commitment Partner Interests shall be paid to the Partners in cash or Securities in proportion to their respective Capital Commitment Profit Sharing Percentages for each Capital Commitment Investment from which such cash or Securities are derived.

The General Partner shall be the liquidator. In the event that the General Partner is unable to serve as liquidator, a liquidating trustee shall be chosen by the affirmative vote of a Majority in Interest of the Partners voting at a meeting of Partners (excluding Nonvoting Special Partners).

Section 9.3. Amounts Reserved Related to Capital Commitment Partner Interests.

(a) If there are any Securities or other property or other investments or securities related to the Partners’ Capital Commitment Partner Interests which, in the judgment of the liquidator, cannot be sold, or properly distributed in kind in the case of dissolution, without sacrificing a significant portion of the value thereof, the value of a Partner’s interest in each such Security or other investment or security may be excluded from the amount distributed to the Partners participating in the related Capital Commitment Investment pursuant to Section 9.2(b). Any interest of a Partner, including his or her pro rata interest in any gains, losses or distributions, in Securities or other property or other investments or securities so excluded shall not be paid or distributed until such time as the liquidator shall determine.

(b) If there is any pending transaction, contingent liability or claim by or against the Partnership related to the Partners’ Capital Commitment Partner Interests as to which the interest or obligation of any Partner therein cannot, in the judgment of the liquidator, be then ascertained, the value thereof or probable loss therefrom may be deducted from the amount distributable to such Partner pursuant to Section 9.2(b). No amount shall be paid or charged to any such Partner on account of any such transaction or claim until its final settlement or such earlier time as the liquidator shall determine. The Partnership may meanwhile retain from other sums due such Partner in respect of such Partner’s Capital Commitment Partner Interest an amount which the liquidator estimates to be sufficient to cover the share of such Partner in any probable loss or liability on account of such transaction or claim.

(c) Upon determination by the liquidator that circumstances no longer require the exclusion of any Securities or other property or retention of sums as provided in paragraphs (a) and (b) of this Section 9.3, the liquidator shall, at the earliest practicable time, distribute as provided in Section 9.2(b) such sums or such Securities or other property or the proceeds realized from the sale of such Securities or other property to each Partner from whom such sums or Securities or other property were withheld.

ARTICLE X

MISCELLANEOUS

Section 10.1. Submission to Jurisdiction; Waiver of Jury Trial. (a) Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision as well as any and all disputes arising out of, relating to or in connection with the termination, liquidation or winding up of the Partnership), whether arising during the existence of the Partnership or at or after its termination or during or after the liquidation or winding up of the Partnership, shall be finally settled by arbitration conducted by a

single arbitrator in New York, New York U.S.A., in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to the dispute fail to agree on the selection of an arbitrator within thirty (30) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of paragraph (a), the General Partner may bring, or may cause the Partnership to bring, on behalf of the General Partner or the Partnership or on behalf of one or more Partners, an action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), each Partner (i) expressly consents to the application of paragraph (c) of this Section 10.1 to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the General Partner as such Partner’s agent for service of process in connection with any such action or proceeding and agrees that service of process upon any such agent, who shall promptly advise such Partner of any such service of process, shall be deemed in every respect effective service of process upon the Partner in any such action or proceeding.

(c) (i) EACH PARTNER HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN NEW YORK, NEW YORK FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF PARAGRAPH (B) OF THIS SECTION 10.1, OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the forum(s) designated by this paragraph (c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another.

(ii) The parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court referred to in paragraph (c)(i) of this Section 10.1 and such parties agree not to plead or claim the same.

(d) Notwithstanding any provision of this Agreement to the contrary, this Section 10.1 shall be construed to the maximum extent possible to comply with the laws of the State of Delaware, including the Delaware Uniform Arbitration Act (10 Del. C. § 5701 et seq.) (the “Delaware Arbitration Act”). If, nevertheless, it shall be determined by a court of competent jurisdiction that any provision or wording of this Section 10.1, including any rules of the International Chamber of Commerce, shall be invalid or unenforceable under the Delaware Arbitration Act, or other applicable law, such invalidity shall not invalidate all of this Section 10.1. In that case, this Section 10.1 shall be construed so as to limit any term or provision so as to make it valid or enforceable within the requirements of the Delaware Arbitration Act or other applicable law, and, in the event such term or provision cannot be so limited, this Section 10.1 shall be construed to omit such invalid or unenforceable provision.

Section 10.2. Ownership and Use of the Blackstone Name. The Partnership acknowledges that Blackstone TM L.L.C. (“TM”), a Delaware limited liability company with a principal place of business at 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000 U.S.A., (or its successors or assigns) is the sole and exclusive owner of the xxxx and name BLACKSTONE and that the ownership of, and the right to use, sell or otherwise dispose of, the firm 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. The Partnership acknowledges that TM owns the service xxxx XXXXXXXXXX for various services and that the Partnership is using the XXXXXXXXXX xxxx and name on a non-exclusive, non-sublicensable and non-assignable basis in connection with its business and authorized activities with the permission of TM. All services rendered by the Partnership under the XXXXXXXXXX xxxx and name will be rendered in a manner and with quality levels that are consistent with the high reputation heretofore developed for the XXXXXXXXXX xxxx by TM and its Affiliates and licensees. The Partnership understands that TM may terminate its right to use BLACKSTONE at any time in TM’s sole discretion by giving the Partnership written notice of termination. Promptly following any such termination, the Partnership will take all steps necessary to change its partnership name to one which does not include BLACKSTONE or any confusingly similar term and cease all use of BLACKSTONE or any term confusingly similar thereto as a service xxxx or otherwise.

Section 10.3. Written Consent. Any action required or permitted to be taken by a vote of Partners at a meeting may be taken without a meeting if a Majority in Interest of the Partners consent thereto in writing.

Section 10.4. Letter Agreements; Schedules. The General Partner may, or may cause the Partnership to, enter or has previously entered, into separate letter agreements with individual Partners, officers or employees with respect to GP-Related Profit Sharing Percentages, Capital Commitment Profit Sharing Percentages, benefits or any other matter, which letter agreements have the effect of establishing rights under, or altering or supplementing, the terms of this Agreement with respect to any such Partner and such matters. The parties hereto agree that any rights established, or any terms of this Agreement altered or supplemented, in any such separate letter agreement, including any Commitment Agreement or SMD Agreement, shall govern solely with respect to such Partner notwithstanding any other provision of this Agreement. The General Partner may from time to time execute and deliver to the Partners schedules which set forth the then current capital balances, GP-Related Profit Sharing Percentages and Capital Commitment Profit Sharing Percentages of the Partners and any other matters deemed appropriate by the General Partner. Such schedules shall be for information purposes only and shall not be deemed to be part of this Agreement for any purpose whatsoever; provided, that this in no way limits the effectiveness of any Commitment Agreement or SMD Agreement.

Section 10.5. Governing Law, Separability of Provisions. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to principles of conflicts of law. In particular, the Partnership has been formed pursuant to the Partnership Act, and the rights and liabilities of the Partners shall be as provided therein, except as herein otherwise expressly provided. If any provision of this Agreement shall be held to be invalid, such provision shall be given its meaning to the maximum extent permitted by law and the remainder of this Agreement shall not be affected thereby.

Section 10.6. Successors and Assigns; Third Party Beneficiaries. This Agreement shall be binding upon and shall, subject to the penultimate sentence of Section 6.3(a), inure to the benefit of the parties hereto, their respective heirs and personal representatives, and any successor to a trustee of a trust which is or becomes a party hereto; provided, that no person claiming by, through or under a Partner (whether such Partner’s heir, personal representative or otherwise), as distinct from such Partner itself, shall have any rights as, or in respect to, a Partner (including the right to approve or vote on any matter or to notice thereof) except the right to receive only those distributions expressly payable to such person pursuant to Article VI and Article VIII. Any Partner or Withdrawn Partner shall remain liable for the obligations under this Agreement (including any Net GP-Related Recontribution Amounts and any Capital Commitment Recontribution Amounts) of any transferee of all or any portion of such Partner’s or Withdrawn Partner’s interest in the Partnership, unless waived by the General Partner. The Partnership shall, if the General Partner determines, in its good faith judgment, based on the standards set forth in Section 5.8(d)(ii)(A) and Section 7.4(g)(ii)(A), to pursue such transferee, pursue payment (including any Net GP-Related Recontribution Amounts and/or Capital Commitment Recontribution Amounts) from the transferee with respect to any such obligations. Nothing in this Agreement is intended, nor shall anything herein be construed, to confer any rights, legal or equitable, on any person other than the Partners and their respective legal representatives, heirs, successors and permitted assigns. Notwithstanding the foregoing, solely to the extent required by the SP Infrastructure III Agreements, (x) the limited partners in SP Infrastructure III shall be third-party beneficiaries of the provisions of Section 5.8(d)(i)(A) and Section 5.8(d)(ii)(A) (and the definitions relating thereto), solely as they relate to any Clawback Amount (for purpose of this sentence, as defined in Section 9.4(a) of the SP Infrastructure III Partnership Agreement) and (y) the amendment of the provisions of Section 5.8(d)(i)(A) and Section 5.8(d)(ii)(A) (and the definitions relating thereto), solely as they relate to any Clawback Amount (for purpose of this sentence, as defined in Section 9.4(a) of the SP Infrastructure III Partnership Agreement), in a manner materially adverse to such limited partners shall be effective against such limited partners only with the 66²⁄₃% Combined Limited Partner Consent (as such term is used in the SP Infrastructure III Partnership Agreement).

Section 10.7. Confidentiality.

(a) By executing this Agreement, each Partner expressly agrees, at all times during the term of the Partnership and thereafter and whether or not at the time a Partner of the Partnership, to maintain the confidentiality of, and not to disclose to any person other than the Partnership, another Partner or a person designated by the Partnership, any information relating to the business, financial structure, financial position or financial results, clients or affairs of the Partnership that shall not be generally known to the public or the securities industry, except as otherwise required by law or by any regulatory or self-regulatory organization having jurisdiction; provided, that any corporate Partner may disclose any such information it is required by law, rule, regulation or custom to disclose. Notwithstanding anything in this Agreement to

the contrary, to comply with Treasury Regulations Section 1.6011-4(b)(3)(i), each Partner (and any employee, representative or other agent of such Partner) may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and tax structure of the Partnership, it being understood and agreed, for this purpose, (1) the name of, or any other identifying information regarding (a) the Partners or any existing or future investor (or any Affiliate thereof) in any of the Partners, or (b) any investment or transaction entered into by the Partners; (2) any performance information relating to any of the Partners or their investments; and (3) any performance or other information relating to previous funds or investments sponsored by any of the Partners, does not constitute such tax treatment or tax structure information.

(b) Nothing in this Agreement shall prohibit or impede any Partner from communicating, cooperating or filing a complaint on possible violations of U.S. federal, state or local law or regulation to or with any governmental agency or regulatory authority (collectively, a “Governmental Entity”), including, but not limited to, the SEC, FINRA, EEOC or NLRB, or from making other disclosures to any Governmental Entity that are protected under the whistleblower provisions of U.S. federal, state or local law or regulation; provided, that in each case such communications and disclosures are consistent with applicable law. Each Partner understands and acknowledges that (a) an individual shall not be held criminally or civilly liable under any U.S. federal or state trade secret law for the disclosure of a trade secret that is made (i) in confidence to a U.S. federal, state, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal, and (b) an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Moreover, a Partner shall not be required to give prior notice to (or get prior authorization from) Blackstone regarding any such communication or disclosure. Except as otherwise provided in this paragraph or under applicable law, under no circumstance is any Partner authorized to disclose any information covered by Blackstone or its affiliates’ attorney-client privilege or attorney work product or Blackstone’s trade secrets without the prior written consent of Blackstone.

Section 10.8. Notices. Whenever notice is required or permitted by this Agreement to be given, such notice shall be in writing (including telecopy or similar writing) and shall be given by hand delivery (including any courier service) or telecopy to any Partner at its address or telecopy number shown in the Partnership’s books and records or, if given to the General Partner, at the address or telecopy number of the Partnership in New York City. Each such notice shall be effective (i) if given by telecopy, upon dispatch and (ii) if given by hand delivery, when delivered to the address of such Partner, the General Partner or the Partnership specified as aforesaid.

Section 10.9. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original and all of which together shall constitute a single instrument. For the avoidance of doubt, a Person’s execution and delivery of this Agreement by electronic signature and electronic transmission (jointly, an “Electronic Signature”), including via DocuSign or other similar method, shall constitute the execution and delivery of a counterpart of this Agreement by or on behalf of such Person and shall bind such Person to the terms of this Agreement. The parties hereto agree that this Agreement and any additional information incidental hereto may be maintained as electronic records. Any Person executing and delivering this Agreement by an Electronic Signature further agrees to take any and all reasonable additional actions, if any, evidencing its intent to be bound by the terms of this Agreement, as may be reasonably requested by the General Partner.

Section 10.10. Power of Attorney. Each Partner hereby irrevocably appoints the General Partner as such Partner’s true and lawful representative and attorney-in-fact, each acting alone, in such Partner’s name, place and stead, to make, execute, sign and file all instruments, documents and certificates which, from time to time, may be required to set forth any amendment to this Agreement or may be required by this Agreement or by the laws of the United States of America, the State of Delaware or any other state in which the Partnership shall determine to do business, or any political subdivision or agency thereof, to execute, implement and continue the valid and subsisting existence of the Partnership. Such power of attorney is coupled with an interest and shall survive and continue in full force and effect notwithstanding the subsequent Withdrawal from the Partnership of any Partner for any reason and shall survive and shall not be affected by the subsequent disability or incapacity of such Partner.

Section 10.11. Partner’s Will. Each Partner and Withdrawn Partner shall include in his or her will a provision that addresses certain matters in respect of his or her obligations relating to the Partnership that is satisfactory to the General Partner and each such Partner and Withdrawn Partner shall confirm annually to the Partnership, in writing, that such provision remains in his or her current will. Where applicable, any estate planning trust of such Partner or Withdrawn Partner to which a portion of such Partner’s or Withdrawn Partner’s Interest is transferred shall include a provision substantially similar to such provision and the trustee of such trust shall confirm annually to the Partnership, in writing, that such provision or its substantial equivalent remains in such trust. In the event any Partner or Withdrawn Partner fails to comply with the provisions of this Section 10.11 after the Partnership has notified such Partner or Withdrawn Partner of his or her failure to so comply and such failure to so comply is not cured within 30 days of such notice, the Partnership may withhold any and all distributions to such Partner until the time at which such party complies with the requirements of this Section 10.11.

Section 10.12. Cumulative Remedies. Rights and remedies under this Agreement are cumulative and do not preclude use of other rights and remedies available under applicable law.

Section 10.13. Legal Fees. Except as more specifically provided herein, in the event of a legal dispute (including litigation, arbitration or mediation) between any Partner or Withdrawn Partner and the Partnership, arising in connection with any party seeking to enforce Section 4.1(d) or any other provision of this Agreement relating to the Holdback, the Clawback Amount, the GP-Related Giveback Amount, the Capital Commitment Giveback Amount, the Net GP-Related Recontribution Amount or the Capital Commitment Recontribution Amount, the “losing” party to such dispute shall promptly reimburse the “victorious party” for all reasonable legal fees and expenses incurred in connection with such dispute (such determination to be made by the relevant adjudicator).
