ARTICLE III

Partnership Capital

     SECTION 3.1 Partnership Capital. As of the date of this Agreement, the Partners have been issued Units and have Funded Commitments in the amounts set forth opposite their names on Schedule 3.1. The Managing General Partner shall record all issuances and redemptions of Units on the books of the Partnership. Except as specifically provided in this Agreement or any Subscription Agreement, no Partner (including the Managing General Partner and the Non-Managing General Partner) shall be required to, and no Limited Partner shall have the right to, contribute additional funds or other property to the Partnership. The Partnership may from time to time incur Indebtedness in accordance with Section 3.6 and issue additional Units in accordance with Sections 3.2 and 3.7.

     SECTION 3.2 Capital Commitments.

     (a) The Partnership may from time to time, in the discretion of the Managing General Partner, issue additional Partnership Units and admit additional Limited Partners to the Partnership. Any Person that acquires Partnership Units for cash (an “Investor”) will acquire such Units pursuant to an agreement (a “Subscription Agreement”) between such Investor and the Partnership pursuant to which such Investor agrees to acquire, and the Partnership agrees to issue, Partnership Units in exchange for Capital Contributions in cash on such terms and conditions as are provided in this Agreement and as may be provided in such Subscription Agreement. A Subscription Agreement shall become effective as of the date it has been executed and delivered by the Investor party thereto and accepted by the Managing General Partner on behalf of the Partnership. Units issuable pursuant to a Subscription Agreement may be issuable in installments, with each installment being issuable, and the Capital Contribution therefor being payable, in accordance with calls for capital (“Capital Calls”) issued pursuant to written notice (the “Capital Call Notice”) to the Investor party to such Subscription Agreement. The total purchase price payable by any Investor under a Subscription Agreement for the Units issuable pursuant thereto is referred to as such Investor’s “Capital Commitment”. Each

21

Investor which acquires any Units pursuant to a Subscription Agreement shall be deemed to be admitted to the Partnership as a Partner immediately upon the payment of the purchase price for the first Units so issued to such Investor. The aggregate amount of Capital Contributions made by a Partner (in cash or property) is referred to herein as such Partner’s “Funded Commitment”, and the portion of the Capital Commitment provided for in any Subscription Agreement that remains unpaid after any closing of a purchase and issuance of Units thereto shall be referred to as the “Unfunded Commitment” of the Partner party to such Subscription Agreement. Except as provided in Section 11.4(c), in no event will any Partner be required to contribute any capital to the Partnership in excess of such Partner’s Capital Commitment.

     (b) If at any time the Managing General Partner determines to raise capital by issuing Capital Calls to Partners having Unfunded Commitments, it shall generally issue such Capital Calls pro rata to each such Partner in proportion to the Unfunded Commitment of each such Partner. However, the Managing General Partner may, in its discretion, issue Capital Calls other than pro rata to the extent required by the terms of any Subscription Agreement or other agreement between the Partnership or the Managing General Partner and one or more Partners, or if the Managing General Partner otherwise deems it advisable to issue Capital Calls in some manner other than pro rata (for example, to assist in achieving or maintaining the status of any REIT in which the Partnership has a direct or indirect interest as a “domestically controlled” REIT). Each Capital Call Notice issued by the Managing General Partner shall specify the account to which Capital Contributions are to be delivered pursuant thereto and the date on which such Capital Contributions are due (“Payment Date”), which date shall be no sooner than ten Business Days after the date such Capital Call Notice is issued. All Capital Contributions made on or before the Payment Date specified in a Capital Call Notice shall be deemed to have been made on such Payment Date.

     SECTION 3.3 Initial Offering Period. The period beginning on February 2, 2004, and ending on November 2, 2004, is referred to herein as the “Initial Offering Period”. The parties acknowledge that all Subscription Agreements entered into prior to the end of the Initial Offering Period provide for the issuance of Units at the Initial Offering Price.

     SECTION 3.4 Initial Investment Period. The three-year period beginning on February 2, 2004, and ending on February 2, 2007, is referred to herein as the “Initial Investment Period”; provided that the Managing General Partner may extend the Initial Investment Period to end on the latest closing date of any Investment with respect to which the Partnership, or the Managing General Partner on behalf of the Partnership, entered into a binding agreement on or prior to the last day of such initial three year period; provided further that the Initial Investment Period shall in no event be extended beyond February 2, 2008. Upon the termination of the Initial Investment Period, as it may be extended pursuant to the preceding sentence, any remaining Unfunded Commitments attributable to Subscription Agreements entered into during the Initial Offering Period shall be canceled automatically and without any further action by any party, and the Managing General Partner shall have no further right to issue Capital Calls, and Investors shall have no further right to purchase Units in respect of such canceled Unfunded Commitments pursuant to any such Subscription Agreement; provided that the foregoing shall not affect (i) the right of the Managing General Partner or the Partnership to pursue any remedies available to it

22

under this Agreement or at law in respect of any default in respect of a Capital Call issued prior to the termination of the Initial Investment Period, or (ii) the obligation of any Partner with respect to a Capital Commitment attributable to a Subscription Agreement entered into after the Initial Offering Period.

     SECTION 3.5 Designation of Class N Units.

     (a) There is hereby designated a class of Partnership Units referred to as “Class N Partnership Units”. Class N Partnership Units shall be identical in all respects to Partnership Units generally, except that holders of Class N Partnership Units shall have no right to participate in any LP Vote, Partner Vote or Fund Vote and shall have no right to vote, consent or make any decision on any matter with respect to which Partners are otherwise permitted to vote, consent or make any decision on under the terms of this Agreement other than as contemplated by clause (i) of the proviso of the first sentence of Section 13.3(a). Each Partner holding Class N Partnership Units hereby further irrevocably waives its corresponding right to vote for a successor general partner under the Act with respect to such Class N Partnership Units, which waiver shall be binding upon such Partner and any Person that succeeds to its interest.

     (b) The Managing General Partner may cause the Partnership to issue Class N Partnership Units in the same manner and on the same terms as this Agreement provides for the issuance of Partnership Units generally. Each Class N Partnership Unit interest shall remain a non-voting interest at all times and shall continue as a non-voting interest with respect to any assignee or other transferee of such interest.

     (c) Except where the context otherwise requires, all references in this Agreement to “Partnership Units” or “Units” shall be deemed to be references to undesignated Partnership Units and Class N Partnership Units, collectively.

     SECTION 3.6 Fund Indebtedness.

     (a) The Managing General Partner shall have the right, at its option, to cause any Fund Entity other than the Partnership to incur or assume Indebtedness from any Person to finance Investments made, directly or indirectly, and to pledge or otherwise encumber assets of any such Fund Entity to secure any such Indebtedness, subject to the following:

     (i) The Partnership shall not consent to NY Trust and its subsidiaries incurring any Indebtedness in excess of 55% of the Current Market Value of the Investments held by NY Trust at the time any such Indebtedness is incurred, and, the Partnership will not consent to NY Trust II and its subsidiaries incurring any Indebtedness in excess of 55% of the Current Market Value of 600 Lexington at the time any such Indebtedness is incurred.

     (ii) The Fund shall not incur any Indebtedness other than the Indebtedness permitted under clause (i) of this Section 3.6(a) unless, after giving effect to such incurrence,

23

     (A) the aggregate amount of such other Indebtedness is not more than 50% of the Current Market Value of all Investments other than the Initial Asset Group at the time any such other Indebtedness is incurred (the “Aggregate Debt Limit”); and

     (B) the total amount of Indebtedness that is secured by any one Investment other than one of the Initial Asset Group shall not exceed 65% of the Current Market Value of such Investment at the time such Indebtedness is incurred (the “Single Asset Debt Limit”).

     (iii) Notwithstanding clause (ii) of this Section 3.6(a), the Managing General Partner may cause the Partnership to consent to the Fund incurring Indebtedness in excess of the Aggregate Debt Limit and/or the Single Asset Debt Limit, if the Managing General Partner determines that it is advisable to do so, provided that, at the time any such excess Indebtedness is incurred, the Managing General Partner makes a reasonable determination that such excess Indebtedness will be repaid within one year after the incurrence of such excess Indebtedness.

     (b) In connection with the incurrence of Indebtedness by any Fund Entity, the Managing General Partner shall have the right, in its discretion, to pledge to the lender the right of the Managing General Partner to issue Capital Calls in respect of the Unfunded Commitments of the Partners, and to enforce the obligations of the Partners to make Capital Contributions in respect thereof, in accordance with the terms and conditions of this Agreement and the Subscription Agreements. Each Partner having an Unfunded Commitment shall, upon the written request of the Managing General Partner, for the benefit of one or more lenders or other Persons extending credit to the Partnership, (A) acknowledge its obligations pursuant to this Agreement and its Subscription Agreement to make Capital Contributions (which may, as determined by the Managing General Partner, include an acknowledgment that the Managing General Partner, or the lender on behalf of the Managing General Partner (in accordance with the agreements between such lender and the Partnership and/or the Managing General Partner), may call such Capital Contributions in accordance with this Agreement and such Partner’s Subscription Agreement to pay the outstanding obligations to such lenders without, except as expressly set forth in this Agreement, defense, counterclaim or offset of any kind); provided that the liability of the Partners to make Capital Contributions shall not be increased thereby and shall not result in the loss of a Partner’s limited liability status under this Agreement, and (B) execute such documents as may be reasonably required to create a security interest in such Partner’s obligations to make such Capital Contributions, which the Managing General Partner may perfect and assign for the benefit of a lender as determined by the Managing General Partner in its sole discretion. For purposes of determining whether the Fund’s Indebtedness is within the Aggregate Debt Limit, Indebtedness secured by a pledge of the Managing General Partner’s right to make Capital Calls in respect of the Partners’ Unfunded Commitments (or in respect of the unfunded commitments of any investor in any Fund Entity) shall not be treated as outstanding Indebtedness; provided that no assets of the Partnership are pledged to secure such Indebtedness other than the right of the Managing General Partner to issue Capital

24

Calls in respect of the Unfunded Commitments of the Partners and to enforce the obligations of the Partners to make Capital Contributions in respect thereof.

     SECTION 3.7 Issuance of Units and Participation Interest.

     (a) The Partnership may issue Units, as determined by the Managing General Partner, in its discretion, to existing or newly-admitted Partners, (i) in exchange for the making by such a Partner (a “Contributing Partner”) of a Capital Contribution to the Partnership in cash, or (ii) in connection with the acquisition, directly or indirectly, of an Investment from such Contributing Partner or an Affiliate of such Contributing Partner by one or more Operating Companies, subject to the following:

     (i) The Partnership may issue Partnership Units at a price per Unit of not less than the Current Unit Value as of the date of issuance.

     (ii) The Partnership may issue Partnership Units in installments pursuant to a Subscription Agreement by which an Investor has made a binding Capital Commitment, with the price per Unit for each issuance of Units pursuant to such Subscription Agreement determined by reference to (A) the Current Market Value of the Properties in which the Partnership has an indirect interest as of the date of such Subscription Agreement (or, if different, as of the date that, and to such extent as, the Investor’s Capital Commitment becomes binding pursuant to the terms of such Subscription Agreement), (B) the acquisition cost of each Property in which the Partnership acquires an interest after such date and on or before the date of such issuance, and (C) the assets and liabilities of the Partnership and its subsidiaries other than interests in Properties as of the date of such issuance.

     (iii) The Partnership may issue Partnership Units to Limited Partners that entered into Subscription Agreements during the Initial Offering Period at a price per Unit equal to $1000 per Unit to the extent provided in any such Subscription Agreement.

     (iv) The Partnership may issue Partnership Units at a price per Unit other than as provided in clause (i), (ii), or (iii) above only with the consent of the Partners by a Super Majority Partner Vote.

     (b) The Managing General Partner will cause the Partnership not to consent to or, to the extent the Partnership Controls the issuance of securities by any such Fund Entity, permit NY Trust, NY Trust II or any other Fund Entity (other than US Core Trust) in which the Partnership has a direct equity interest (or any subsidiary of any such Fund Entity) to issue equity interests to third party investors other than as contemplated by clause (i) or (ii) of Section 3.7(a) without the consent of the Partners by a Super Majority Partner Vote. The Managing General Partner will cause the Partnership not to consent to or, to the extent the Partnership Controls the issuance of securities by any such Fund Entity, permit US Core Trust or any subsidiary of US Core Trust (other than US Core Properties and subsidiaries of US Core Properties) to issue equity interests to third party

investors other than as contemplated by clause (i) or (ii) of Section 3.7(a) without the written consent of Voting Fund Investors holding, without duplication, sixty-six and two-thirds percent (66 2/3%) or more of the aggregate outstanding equity interests in the Partnership and US Core Trust held by Voting Fund Investors, excluding any equity interest which is specifically designated a non-voting interest under the Constituent Documents of the issuer of such equity interest. The Managing General Partner will take such action as is necessary to prevent US Core Properties or any Fund Entity that US Core Properties Controls from issuing equity interests to third party investors other than as contemplated by clause (i) or (ii) of Section 3.7(a) without the written consent of Voting Fund Investors holding, without duplication, sixty-six and two-thirds percent (66 2/3%) or more of the aggregate outstanding equity interests in the Partnership, US Core Trust and US Core Properties held by Voting Fund Investors, excluding any equity interest which is specifically designated a non-voting interest under the Constituent Documents of the issuer of such equity interest. This Section 3.7(a) is subject to Section 5.3(b)(iv).

     (c) (i) Effective as of the date of the Second Restated Agreement, the Partnership issued to each of Hines and SLR a limited partnership interest denominated as a “Participation Interest.” The Participation Interest is an equity interest in the Partnership which is granted in consideration for services rendered by Hines and SLR as Investment Advisors to the Managing General Partner and the Partnership pursuant to the Advisory Agreement. The Participation Interest is in addition to, and distinct from, the Units described above, and any references to “Units” or “Partnership Units” shall not be deemed to include the Participation Interest. A Partner’s percentage interest attributable to its Participation Interest (if any), together with the percentage of the total outstanding Units held by it, equal its Percentage Interest in the Partnership. The Participation Interest is an interest solely in profits and shall not have any Capital Commitment or initial Capital Account associated with it. It is intended that the Participation Interest constitute a profits interest within the meaning of Section 2.02 of IRS Revenue Procedure 93-27, 1993-2 C.B. 343.

     (ii) The formula for calculation of the Participation Interest is included in the definition of Percentage Interest in Section 1.1, and Schedule 5.9 provides an example of how the Percentage Interest for the holder of a Participation Interest is calculated. The Participation Interest is intended to provide each Investment Advisor holding it with an interest in the Partnership that approximates the interest it would acquire if it received Asset Management Fees and Acquisition Fees after the Initial Investment Period in the same amounts payable in respect of such fees during the Initial Investment Period and then invested half of such amounts in the Partnership through the acquisition of additional Partnership Units. (However, since the Participation Interest is a profits interest, this interest will be substantially economically equivalent to the ownership of Partnership Units only if the Partnership has adequate gain or profit to allocate to the holder of the Participation Interest.) Without considering the effect of additional equity investments or redemptions by existing or new Partners, the grant of the Participation Interest has the effect of decreasing the Percentage Interest of all Unaffiliated Limited Partners after the Initial Investment

26

Period as the Percentage Interest associated with the Participation Interests increases in a manner corresponding to the accrual of additional Asset Management Fees and Acquisition Fees that would occur if such fees were payable in cash after the Initial Investment Period in the same amounts as such fees are payable during the Initial Investment Period pursuant to the terms of this Agreement. This is accomplished by the Unit cancellation procedure described in Section 5.9. (Schedule 5.9 provides an example of Unit cancellations as contemplated by Section 5.9.)

     (iii) SLR may, at any time prior to the end of the Initial Investment Period, elect to return its Participation Interest to the Partnership by giving written notice to such effect to the Managing General Partner. In such event, the Managing General Partner shall amend this Agreement and the Advisory Agreement (in a manner reasonably acceptable to SLR) as necessary to provide for (A) only Hines having a Percentage Interest calculated by reference to a Participation Interest, and (B) the payment to the Managing General Partner for the benefit of SLR of additional cash amounts in respect of Asset Management Fees and Acquisition Fees to which SLR would be entitled under the Advisory Agreement if the Partnership continued to pay such fees after the Initial Investment Period in the manner that such fees are required to be paid under this Agreement during the Initial Investment Period.

     SECTION 3.8 Redemption Rights. Subject to and in accordance with the provisions of this Section 3.8, each Partner shall have the right (a “Redemption Right”) to request that the Partnership redeem for cash at the Current Unit Value in the case of Units, or at the Current Participation Interest Value in the case of a Participation Interest, all or a portion of the Units or Participation Interest held by such Partner by delivering a notice (a “Notice of Redemption”) to the Partnership and the Managing General Partner specifying the number of Units or the portion of the Participation Interest held by such Partner (a “Redeeming Partner”) that it requests to be redeemed at any time within the last 45 days of any calendar year ending after the later of (i) the last day of the Initial Investment Period and (ii) the first anniversary of the date such Partner acquired the Units or such portion of its Participation Interest that it seeks to redeem. If, and beginning with the first day of the first taxable year in which, the Partnership no longer qualifies for the Private Placement PTP Exemption, the Redemption Right shall comply with the requirements of Regulations Section 1.7704-1(f) and shall be construed and administered in accordance therewith. The Managing General Partner may modify the Redemption Right from time to time in its discretion to ensure that the terms of the Redemption Right comply and continue to comply with such requirements. If a Partner requests a redemption pursuant to the first sentence of this Section 3.8 (a “Liquidating Redemption”), the Managing General Partner shall use its reasonable best efforts to cause the Partnership to redeem the number of Units or the portion of the Participation Interest specified in the Notice of Redemption for cash at the Current Unit Value in the case of Units, or at the Current Participation Interest Value in the case of a Participation Interest, in each case as of the date of redemption, on or before the last day of the calendar year following the year in which such Notice of Redemption was delivered, subject to the following:

27

     (a) In no event shall the Partnership be required to redeem for cash in any calendar year Partnership Units and Participation Interests which, when taken together with all interests in US Core Trust and US Core Properties which Fund Investors having interests therein are seeking to redeem pursuant to corresponding redemption rights under the Constituent Documents of such Entities, exceed, in the aggregate, 10% of the total equity capitalization of the Partnership, US Core Trust and US Core Properties (calculated without duplication of equity held directly or indirectly in any such Entity by any other such Entity) as of the first day of such calendar year. If, for any calendar year, Partners and such Fund Investors request such liquidating redemptions in excess of such 10% limit, then each Partner entitled to participate in such redemption shall be entitled to redeem its pro rata share of the total equity in the Partnership, US Core Trust and US Core Properties requested to be redeemed in such calendar year based on the amount of such equity requested to be redeemed in each such Fund Investor’s Notice of Redemption.

     (b) If more than one Fund Investor submits a request for a Liquidating Redemption in a calendar year, then funds available to effect such redemptions shall be applied pro rata to the redemption of the interests in the Partnership, US Core Trust and/or US Core Properties subject to each such Fund Investor’s Notice of Redemption, based on such Fund Investor’s share of the total amount of equity to be redeemed.

     (c) In no event will any Units or Participation Interests (or interests in US Core Trust or US Core Properties) be redeemed pursuant to a Liquidating Redemption to the extent that (i) the Managing General Partner determines in good faith that such redemption would be inconsistent with the best interests of the Partnership or any Operating Entity, (ii) such redemption would result in any REIT in which the Partnership has a direct or indirect interest ceasing to be a “domestically controlled REIT” as defined in Section 897(h)(4) of the Code or would violate or result in a violation of the Constituent Documents of any Operating Company in which the Partnership has a direct or indirect interest, or (iii) the Partnership is unable to raise or acquire sufficient funds to make such Liquidating Redemption on terms acceptable to the Partnership, as determined by the Managing General Partner in good faith.

     (d) If, and beginning with the first day of the first taxable year in which, the Partnership no longer qualifies for the Private Placement PTP Exemption:

     (i) A Partner shall be entitled to exercise the Redemption Right only if (x) the redemption or purchase of the Partner’s Units and/or Participation Interest would constitute a Private Transfer or (y) the Percentage Interest attributable to the Units and Participation Interest to be redeemed, when aggregated with other Transfers of Partnership Interests within the same taxable year of the Partnership (but not including Private Transfers), would constitute a Percentage Interest of ten percent (10%) or less in the Partnership.

     (ii) The Managing General Partner may establish such policies and procedures as it may deem necessary or desirable in its discretion, including imposing limitations on the number of Units and portion of Participation Interest

28

with respect to which the Redemption Right may be exercised during any period of time shorter than a calendar year (and causing similar limitations to be imposed with respect to redemptions of interests in US Core Trust and US Core Properties) and establishing procedures to allocate the ability to exercise the Redemption Right among the Partners (and causing similar procedures to be established with respect to US Core Trust and US Core Properties).

     (iii) The restrictions set forth in subparagraphs (i) and (ii) of this Section 3.8(d) shall continue in effect until such time as the Partnership is no longer potentially subject to classification as a publicly traded partnership, as defined in Code Section 7704, in the absence of such restrictions, as determined by the Managing General Partner in its discretion. The restrictions set forth in such clauses (i) and (ii), together with the restrictions on the Transfer of Partnership Interests set forth in Section 10.5(b)(ii), are intended to limit transfers of interests in the Partnership in such a manner as to permit the Partnership to qualify for the safe harbors from treatment as a publicly traded partnership set forth in Treasury Regulations Sections 1.7704-1(d), (e), (f) and (j) and shall be construed and administered in accordance therewith. The Managing General Partner may modify the restrictions set forth in such clauses (i) and (ii), and the provisions of Section 10.5(c), from time to time in its discretion to ensure that the Partnership complies and continues to comply with the requirements of the Code and Regulations described above.

     (e) Each Notice of Redemption requesting a Liquidating Redemption will expire and be of no further force or effect as of the last day of the calendar year following the year in which such Notice of Redemption was delivered. A Partner (or other Fund Investor) will be entitled to participate in Liquidating Redemptions in any given calendar year only to the extent of the Units and the portion of the Participation Interest (or other interest in the Fund) subject to a Notice of Redemption requesting a Liquidating Redemption within the last forty-five days of the preceding calendar year.

     (f) A Limited Partner shall not be entitled to exercise a Redemption Right if it prejudices or affects the continuity of the Partnership for purposes of Code Section 708. Prior to any such redemption, the Managing General Partner may require an opinion of counsel, which counsel and opinion shall be satisfactory to the Managing General Partner, to the effect that such redemption will not cause adverse tax consequences to the non-redeeming Partners, and such Limited Partner exercising the Redemption Right shall be responsible for paying said counsel’s fee for such opinion.

     SECTION 3.9 Priority Redemption Rights. In connection with the issuance of Units to a Contributing Partner, the Partnership may agree, subject to the terms of any outstanding Priority Redemption Rights, in the sole discretion of the Managing General Partner, as part of the terms and conditions for such issuance, to grant such Contributing Partner a right to redeem all or a portion of the Units issued to such Limited Partner in such issuance at a redemption price equal to the Current Unit Value at the time of redemption on or before a specified date or dates (any such preferential or modified redemption right, a “Priority Redemption Right”). Pursuant to any such agreement, the Managing General Partner may apply any Capital Cash Flow and any funds

29

received from Capital Contributions of Partners that would otherwise be available for making distributions to the Partners or redeeming Units pursuant to Redemption Rights generally to the making of any redemptions required to be made pursuant to any Priority Redemption Rights. Redemptions made or required to be made pursuant to the exercise of Priority Redemption Rights are referred to herein as “Priority Redemptions”.

     SECTION 3.10 Hines Bridge Equity and Priority Redemption Right. Prior to the date hereof, the Managing General Partner and the Hines Limited Partner have collectively made Capital Contributions to the Partnership in excess of the Hines Capital Requirement at a price per Unit equal to the Initial Offering Price. Affiliates of Hines may from time to time in the future contribute equity to the Partnership and/or one or more Operating Companies or other Fund Entities which, taken together with other contributions by Affiliates of Hines, exceed the Hines Capital Requirement if the Managing General Partner determines that such contributions are necessary or advisable for the Fund to finance an Investment, meet the domestic control requirements set forth in the Constituent Documents of any Operating Company that is a REIT or for other purposes deemed appropriate by the Managing General Partner. Any such future contributions shall be at a price per Unit (or equivalent interest in another Fund Entity) equal to the Current Unit Value (or its equivalent), as of the date of the contribution. All past contributions and future contributions in excess of the Hines Capital Requirement by Affiliates of Hines to the Partnership or any Operating Company or other Fund Entity are referred to herein as “Hines Bridge Equity”. Notwithstanding any other provision of this Agreement, the Managing General Partner shall cause the Partnership (or applicable Operating Company) to apply the proceeds of all Capital Contributions made to the Partnership or any Operating Company from and after the date hereof to the redemption of any Hines Bridge Equity, to the extent that the Managing General Partner reasonably determines that such Hines Bridge Equity is no longer required. Such redemption shall be for cash in an amount per Unit (or equivalent interest) equal to the price per Unit (or equivalent interest) paid by the applicable Hines Affiliate for such interest, with appropriate adjustments for assets and liabilities of the Partnership other than its interests in Properties as of the date of redemption. The right to have any Hines Bridge Equity redeemed pursuant to this Section 3.10 shall be a Priority Redemption Right of the Hines Affiliate that contributed such equity. To the extent the Managing General Partner, the Hines Limited Partner or another Affiliate of Hines elects to exercise such Priority Redemption Right, the Managing General Partner may require all Partners whose Unfunded Commitments are greater than zero to make Capital Contributions in accordance with Section 3.2 up to the full amount of such Unfunded Commitments to the extent necessary to fund such redemption. Notwithstanding the foregoing, each of the Hines Limited Partner, the Managing General Partner and any other Affiliate of Hines that contributes Hines Bridge Equity may, in its sole and absolute discretion, waive or defer, in whole or in part, the exercise of the Priority Redemption Right granted to it pursuant to this Section 3.10. Each Affiliate of Hines that contributes or has contributed Hines Bridge Equity to the Partnership or any other Fund Entity shall be a third party beneficiary of this Section 3.10.

     SECTION 3.11 Hines Investment. The Managing General Partner, the Hines Limited Partner and/or such other Affiliates of Hines as the Managing General Partner may determine from time to time, shall maintain Unrecovered Capital in the Fund in an aggregate amount of not less than the greater of (i) 1% of the Unrecovered Capital of all Fund Investors, or (ii) $25 million (the “Hines Capital Requirement”); provided that, for purposes of determining whether

30

the Hines Capital Requirement is met, (1) any amounts invested by Hines or any Affiliate of Hines in Hines Real Estate Investment Trust, Inc. or Hines REIT Properties, L.P., including, without limitation, any participation or profits interests granted to Hines or any Affiliate of Hines in either such Entity, shall be deemed to constitute Unrecovered Capital of Hines or such Affiliate of Hines in the Fund, and (2) the Non-Managing General Partner shall be deemed not to be a Fund Investor. In connection with any contribution of capital to an Operating Company by Fund Investors, the issuance of additional Partnership Units by the Partnership, the issuance of additional equity securities by any Operating Company or otherwise, the Managing General Partner shall, or shall cause an Affiliate of the Managing General Partner to, acquire additional Partnership Units or equity securities of one or more Operating Companies or other Fund Entities at the Current Unit Value (or its equivalent) to the extent necessary to comply with the Hines Capital Requirement. In order to manage the equity interests in the Fund held by the Managing General Partner and its Affiliates for purposes of complying with the Hines Capital Requirement, (A) the Managing General Partner, the Hines Limited Partner or any other Affiliate of Hines may, at any time, at the discretion of the Managing General Partner, contribute interests such Person holds in any Operating Company in which the Partnership has an interest to the Partnership in exchange for Partnership Units at Current Unit Value; and (B) the Managing General Partner may, at any time, in its discretion, cause the Partnership to exchange, at Current Unit Value, interests in any Operating Company held by the Partnership for interests in another Operating Company in which the Partnership holds an interest, or for Partnership Units, held by the Managing General Partner, the Hines Limited Partner or any other Affiliate of Hines; provided that, in any such case, such exchange does not result in the recognition of material amounts of taxable income or gain by the Partnership or any Fund Entity. Neither the Managing General Partner nor any other Affiliate of Hines shall be in breach of this Agreement if at any time the Hines Capital Requirement is not met as a result of dilution following the issuance of Partnership Units or interests in any Fund Entity so long as the Managing General Partner takes, or causes any Affiliate to take, such action as is necessary to cause the Hines Capital Requirement to be met as promptly as practicable following any such issuance.

33

Partner (including, if applicable, the Non-Managing General Partner) or Fund Investors, unless the approval or consent required by this Agreement has been obtained.

     SECTION 4.3 Time Commitment.

     (a) The Managing General Partner shall, and shall cause its Affiliates and their respective employees, officers and agents to, devote to the Partnership, Operating Companies and Investments such time as shall be necessary to conduct the business and affairs of the Partnership, Operating Companies and Investments in an appropriate manner consistent with the terms of this Agreement and the Constituent Documents of each Operating Company. The Partners acknowledge that the Managing General Partner and other Affiliates of Hines and their respective employees, officers and agents may also engage in activities unrelated to the Fund and may provide services to Persons other than the Partnership, the Operating Companies or any of their Affiliates.

     (b) The Managing General Partner shall cause the Management Team to devote such time as the Managing General Partner reasonably determines is necessary to manage and operate the business affairs of Fund in an appropriate manner consistent with the terms of this Agreement.

     SECTION 4.4 Outside Investments. So long as the Fund has the capacity to make new Investments, the Managing General Partner will not and will cause each Affiliate of Hines not to make (i) any new equity investment which satisfies the Investment Guidelines (other than through an interest in the Fund) or (ii) act as a manager or the primary source of transactions on behalf of another pooled investment fund focusing on substantially the same types of investment opportunities as those targeted by the Fund; provided that such restrictions shall not apply to the following:

     (a) any investment which the Managing General Partner has decided not to make or pursue based on a good faith determination that such investment is inappropriate or inadvisable for the Fund, whether due to capacity, diversification, rate of return objectives or other considerations; provided that to the extent the Managing General Partner determines in good faith that it is desirable for the Fund to make some but not all of a particular investment, then the Fund may make such investment to such extent and the Managing General Partner or another Affiliate of Hines may co-invest with the Fund in such investment on a side-by-side basis on terms no more favorable than those applicable to the Fund’s share of the investment;

     (b) any investment by the Hines U.S. Office Value Added Fund, or any other fund or investment program affiliated with Hines which has investment policies and objectives which differ substantially from those of the Fund and which, in the good faith judgment of the Managing General Partner, does not compete in any material way for investments that would be suitable for the Fund;

     (c) any investment in an office building more than 75% leased to a single tenant under a lease having at least two years remaining on its term (excluding extension options);

34

     (d) (passive investments (i.e., investments which do not involve active participation in management by any Affiliate of Hines); and

     (e) any investment made by NOP pursuant to an investment opportunity allocated to NOP in accordance with the Hines investment allocation procedure described in Schedule 4.4.

     SECTION 4.5 Transactions with Affiliates. Except for transactions the terms of which are expressly contemplated or approved by this Agreement or any Approved Agreement, neither the Managing General Partner nor any other Affiliate of Hines shall engage in any material transaction with the Partnership or any Fund Entity unless the terms of such transaction have been approved by the Advisory Committee and the Managing General Partner. The Advisory Committee will not unreasonably withhold its consent to any such transaction proposed by the Managing General Partner. The Managing General Partner will not consent to or propose to the Advisory Committee any such transaction which the Managing General Partner does not believe is on fair market terms for comparable transactions.

     SECTION 4.6 Co-Investment Opportunities. The Managing General Partner may consent, on behalf of the Partnership, to an Operating Company permitting one or more Persons, including Fund Investors and Affiliates of the Managing General Partner, co-investing in Properties in which the Fund invests if the Managing General Partner determines that it is not in the best interest of the Fund to invest (or that the Fund is prohibited from investing pursuant to the terms of this Agreement or any Approved Agreement) the entire amount required to fund such Investment because of the size of or risk inherent in such Investment or due to legal, regulatory or tax considerations. Any such co-investment made by a Fund Investor or an Affiliate of a Fund Investor may be made through an investment vehicle in which such co-investor has an interest separate from its interest in the Fund, and if the Managing General Partner and/or its Affiliates are the co-investor, such co-investment shall have economic terms that are materially no more favorable to the Managing General Partner and/or its Affiliates, as applicable, than the terms of this Agreement or the terms contemplated by any Approved Agreement. If the Managing General Partner, Hines or any Affiliate of the Managing General Partner or Hines co-invests in a Property with the Fund, then, unless otherwise approved by the Advisory Committee, the Managing General Partner, Hines or such Affiliate, as applicable, shall be required to dispose of its interest in such Property at the same time as the Fund disposes of its interest in the Property on terms no more favorable to such Person than those received by the Fund. For the avoidance of doubt, nothing in this Section 4.6 shall restrict (i) the offering of co-investment rights to Co-Investors (as defined in the GM Investor Rights Agreement) to the extent permitted by the GM Investor Rights Agreement, or (ii) any Operating Company or other Fund Entity from entering into partnership or other joint venture arrangements with third parties providing for shared ownership of an Investment to the extent such arrangements are deemed necessary or desirable to facilitate the acquisition, operation or disposition of, or otherwise add value to, any Investment.

     SECTION 4.7 Other Activities not Restricted. Except as provided in Section 4.2(c), Sections 4.3 through 4.6 and Article V, this Agreement shall not be construed in any manner that precludes the Managing General Partner or any other Affiliate of Hines, or any of their

35

respective officers, employees or agents from engaging in any activity whatsoever permitted by applicable law.

ARTICLE V

Partnership Management

     SECTION 5.1 Fund Structure.

     (a) The Partnership will invest in real estate properties in the United States indirectly through Operating Companies in which the Partnership holds or hereafter acquires a direct or indirect interest. The Partnership may from time to time organize such Operating Companies as the Managing General Partner deems necessary or advisable to accomplish the objectives of the Partnership, so long as the Constituent Documents of any such Operating Company, together with any other agreements entered into in connection with the organization of such Operating Company, provide the Partnership, the Managing General Partner or another Hines Controlled Entity, directly or indirectly, with Control of such Operating Company. The Partnership, each Operating Company and any Entity in which an Operating Company holds a direct or indirect interest is sometimes referred to in this Agreement as a “Fund Entity”. The Partnership and all other Fund Entities collectively are sometimes referred to herein as the “Fund”. Each Partner, and each Person that holds an equity interest in any Operating Company or other Fund Entity or which makes an equity investment in any Property in which any Operating Company invests, and which is designated as such by the Managing General Partner, shall be deemed a “Fund Investor”. The Managing General Partner shall promptly notify each Partner of the identity and notice address of any Person designated a Fund Investor.

     (b) As of the date of this Agreement, the Fund consists of the Partnership, NY Trust and the subsidiaries of NY Trust, NY Trust II and the subsidiary of NY Trust II and US Core Trust and the subsidiaries of US Core Trust, including US Core Properties and the subsidiaries of US Core Properties. The organizational structure of the Fund is as set forth on Schedule 5.1. The Partnership shall take such action as from time to time may be necessary to ensure that the Partnership has the right, by virtue of share ownership, voting agreement or otherwise, to designate a majority of the Board of Trustees of US Core Trust and to vote or direct the vote of a majority of the voting securities of US Core Trust at anytime outstanding. The Partnership shall not, without the consent of the Partners by a Majority Partner Vote, consent to or take any action that results in (i) US Core Trust ceasing to be the general partner of US Core Properties, or (ii) US Core Trust issuing any equity securities having rights, privileges or preferences superior to those of the securities of US Core Trust held by the Partnership (provided that, the Partnership may, without any such consent, cause US Core Trust to issue securities having preferential or modified redemption rights to the same extent that the Partnership may grant Priority Redemption Rights as contemplated by Section 3.9). Notwithstanding the foregoing, the Managing General Partner may, without the consent of any other Partner, cause the Partnership to consent to the issuance by US Core Trust, NY Trust, NY Trust II and any other REIT in which the Partnership acquires a direct or indirect interest, for

36

the purpose of ensuring that such REIT obtains and maintains a sufficient number of shareholders for such REIT to satisfy the “100 shareholder test” applicable to REITs under the Code, of a preferred class of equity security having certain rights, privileges or preferences superior to those of the securities of such REIT held by the Partnership; provided, that (i) such issuance does not result in the Partnership ceasing to Control such REIT, (ii) the Managing General Partner determines that the terms of such securities and of their issuance by such REIT are commercially reasonable, and (iii) such REIT does not issue more than $200,000.00 face amount of such preferred securities in the aggregate.

     SECTION 5.2 Investment Guidelines.

     (a) Each Operating Company will invest, indirectly through one or more Fund Entities, in real estate properties in the United States in accordance with the Investment Guidelines. Any real estate property in which the Fund invests is referred to herein as a “Property”. An Operating Company’s interests in Properties and in any intermediate Entity through which such Operating Company invests in a Property are referred to generally as “Investments.” The Partnership will maintain in Temporary Investments or cash any funds of the Partnership that are not invested in Operating Companies, distributed to the Partners or applied toward the expenses of the Partnership.

     (b) The investment objective of the Partnership is to (A) achieve an average cash return to Limited Partners of 7% to 8% on their capital invested in respect of Units and (B) generate an internal rate of return to Limited Partners of 10% to 12% on their capital invested in respect of Units, net of Partnership expenses, in each case over an assumed ten year holding period, by investing in and funding Operating Companies which adhere to the following guidelines (the “Investment Guidelines”):

     (i) Each Operating Company will invest in existing office properties that the Managing General Partner believes are desirable long term “core” holdings. Each Operating Company will target high quality properties in attractive Central Business District (“CBD”) and suburban locations, with the expectation that approximately 70% of the Partnership’s Committed Capital will be invested in CBD Properties.

     (ii) An Operating Company may invest in mixed-use Properties (i.e., some part of value and/or operating income is attributable to non-office components), so long as at least 70% of the projected net operating income of any such Property is attributable to office components.

     (iii) An Operating Company will not invest in raw land, except where such investment is incidental to an investment in an existing developed office property or made as part of an investment in a portfolio of existing office properties; provided that, in any case, subject to clause (v) below, an Operating Company shall not make an investment in raw land if such investment would cause the value of the Fund’s total investment in raw land to exceed 2% of the total value of all Investments of the Fund at the time the Operating Company makes such investment.

     (iv) Subject to clause (v) below, an Operating Company will not invest in any property or asset that has a material hotel or lodging component.

     (v) Notwithstanding clauses (iii) and (iv) of this Section 5.2(b), an Operating Company may make an investment in raw land or hotel or lodging assets that would otherwise be prohibited by such clauses (iii) and (iv) if such investment is made as part of a transaction involving existing office properties, and such Operating Company has a reasonable plan for disposing of the investment in the prohibited assets to the extent necessary to comply with the requirements of such clauses (iii) and (iv) within twelve months after making such investment.

     (vi) After the Initial Investment Period, the Partnership will not provide funding to an Operating Company for investment in any single Investment in excess of 25% of the Partnership’s Committed Capital; provided that the Partnership may provide funding for an Investment by an Operating Company that exceeds such 25% limit (but which does not in any event exceed 50% of the Partnership’s Committed Capital), if such Operating Company has a reasonable plan, in the judgment of the Managing General Partner, to reduce the Committed Capital of the Partnership invested in such Investment to 25% or less of the Committed Capital of the Partnership within nine months after making such investment.

     SECTION 5.3 Management Board.

     (a) The Managing General Partner shall be subject to the oversight of a management board (the “Management Board”). The Management Board will initially have seven members. The Managing General Partner shall have the right to appoint five members of the Management Board and SLR shall have the right to appoint two members (each, an “SLR Designee”).

Each member of the Management Board shall serve until the removal, resignation, death or incapacity of such member. Any member of the Management Board may be removed or replaced at any time by the party that appointed such member with or without cause. Members of the Management Board shall not receive any compensation from the Partnership for their services as such.

     (viii) approve or make material modifications to any annual capital or operating budget of such Operating Company, or

     (ix) such other matters as are specified in this Agreement.

     (d) Meetings of the Management Board may be called at any time by the Managing General Partner, the President or by any member of the Management Board on five Business Days’ written notice, which notice shall include a description of the matters to be discussed at such meeting. Action may be taken by the Management Board at any meeting at which a quorum is present, which quorum shall consist of a majority (attending personally or represented by proxy) of the persons then serving as members of the Management Board; provided that a quorum shall not exist at any meeting unless at least one SLR Designee is present (either personally or represented by proxy) at such

39

meeting. Notwithstanding the preceding sentence, if none of the SLR Designees, acting in good faith, is able to attend a meeting of the Management Board on the meeting date specified in the notice of such meeting or within two Business Days thereafter, the quorum for such meeting shall consist of a majority (attending personally or represented by proxy) of the persons then serving as members of the Management Board (other than the SLR Designees). Members of the Management Board may participate in meetings in person, including by telephone conference call at which all persons participating can hear and be heard, and shall be also deemed to participate at any meeting at which (and to the extent which) such member is represented by proxy.

     (e) Any matter presented to the Management Board for its consideration at a meeting duly called and held in accordance with this Section 5.3 at which a quorum is present shall be deemed to have been approved and consented to by the Management Board if a majority of the members of the Management Board who are present at the meeting or represented by proxy vote in favor of such action; provided that such majority must include at least one SLR Designee in the case of any consent to be given by the Management Board with respect to any of the following:

     (i) solicitation of Persons resident in Japan or East Asia as prospective investors in the Partnership, and the acceptance by the Managing General Partner, on behalf of the Partnership, of any subscription for Units by any such Person,

     (iii) any change in the members of the Management Board appointed by SLR; or

     (iv) any change in the name of the Partnership.

          Notwithstanding the provisions of paragraph (d) of this Section 5.3, and subject to the provisions of paragraph (e) of this Section 5.3, any action required or permitted to be taken at a meeting of the Management Board may be taken without a meeting, without prior notice, and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by such members of the Management Board as would be necessary to approve such action at a meeting of the Management Board at which all members were present.

     (f) Notwithstanding the provisions of this Section 5.3, no Investment will be considered by the Management Board for its approval without endorsement of such Investment by the President.

     (g) If SLR, after the date hereof and prior to December 31, 2005, ceases to hold any Partnership Interest, then unless, on or before December 31, 2005, SLR and/or Affiliates of SLR, (1) contribute at least $25 million to the capital of the Fund in exchange for Partnership Units (or other units of Fund equity), or (2) raise, on behalf of the Fund, as least $25 million in capital contributions or capital commitments to the Fund; then the SLR Designees on the Management Board and on any governing body of any Fund Entity shall cease to have any voting rights on any such governing body but

40

shall be observers to the meetings of each such governing body; provided that if neither of the events described in clauses (1) and (2) of this Section 5.3(h) has occurred on or before the fifth anniversary of the date as of which SLR and its Affiliates cease to hold any Partnership Units, then, on such date, all rights of SLR and the SLR Designees under this Agreement shall cease, and the Managing General Partner shall, without the consent of SLR or any other party, amend this Agreement to reflect that such is the case.

     SECTION 5.4 Advisory Committee.

     (a) The Partnership shall have a committee (the “Advisory Committee”) consisting of Fund Investors or their representatives or designees selected by the Managing General Partner; provided that no member of the Advisory Committee shall be an Affiliate of the Managing General Partner (or a designee or representative thereof). The Managing General Partner will meet with the Advisory Committee at least semi-annually to consult on various matters concerning the Partnership, including financial statements and appraisals, the status of existing investments and such other matters as the Managing General Partner may determine or any member of the Advisory Committee may reasonably propose.

     (b) The Advisory Committee’s approval will not be required for any actions or decisions of the Managing General Partner or the Management Board, except that approval of the Advisory Committee shall be required for:

     (i) any transaction between the Partnership or any Fund Entity, on the one hand, and the Managing General Partner, Hines or any Affiliate of the Managing General Partner or Hines, on the other hand, other than: (A) the provision of services pursuant to any Property Services Agreement, (B) the leasing of a limited amount of office space in a Property on market terms by Hines or any of its Affiliates for conducting its operations, (C) the sale of Units or of any equity securities (other than the Participation Interest) of any Fund Entity to Hines or any of its Affiliates at the same price per share or unit as is offered to other investors or, if no such securities are being offered to unaffiliated investors, at the Current Unit Value or at such other price as may be approved by the Partners by a Super Majority Vote, (D) the redemption of Partnership Interests or interests in other Fund Entities held by Affiliates of Hines pursuant to the terms of this Agreement and/or the Constituent Documents of the applicable Fund Entity, (E) the execution, delivery or performance of any Approved Agreement, and (F) any other transaction specifically permitted by this Agreement.

     (ii) the ratification of any Appraiser selected by the Managing General Partner, pursuant to Section 5.9 hereof;

     (iii) any in kind distribution by the Partnership of publicly traded securities; and

     (iv) notwithstanding clause (i)(A) above, any increase of fees payable to any Property Manager pursuant to any Property Services Agreement to

41

amounts greater than those provided for in the Property Services Agreement Form.

     (c) Any action of, or approval required by, the Advisory Committee shall require the vote of members of the Advisory Committee who account for at least a majority of the aggregate Committed Capital collectively held by Fund Investors represented on the Advisory Committee.

     (d) The quorum required for a meeting of the Advisory Committee shall be a majority in interest of its members (determined by reference to the Committed Capital of the Fund Investors represented by such members). Members of the Advisory Committee may participate in a meeting of the Advisory Committee by means of conference telephone or video conferencing by means of which all persons participating in the meeting can hear and be heard. Any member of the Advisory Committee who is unable to attend a meeting of the Advisory Committee may grant in writing to another member of the Advisory Committee or any other Person such member’s proxy to vote on any matter upon which action is to be taken at such meeting. The Advisory Committee shall conduct its business by such procedures as a majority of its members consider appropriate.

     (e) Any action required or permitted to be taken at a meeting of the Advisory Committee may be taken without a meeting, without prior notice, and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by such members of Advisory Committee as would be necessary to approve such action at a meeting of the Advisory Committee at which all members were present; provided, that all members of the Advisory Committee received notice of the solicitation of consent at least five (5) days prior to the effectiveness thereof.

     (f) No fees shall be paid by the Partnership or any Operating Company to members of the Advisory Committee for their services as such, but the members of the Advisory Committee shall be reimbursed by the Partnership for all reasonable out-of-pocket expenses incurred in attending meetings of the Advisory Committee.

     (g) Any member of the Advisory Committee may resign upon delivery of written notice from such member to the Managing General Partner, and shall be deemed removed if the Limited Partner that the member represents requests such removal in writing to the Managing General Partner or becomes a Defaulting Partner. Any vacancy in the Advisory Committee created by the resignation or death of a member or by the removal of a member at the request of the Limited Partner represented by such member shall be filled by a representative of the Limited Partner represented by such member.

     (h) The Managing General Partner may, in its discretion, grant to any Fund Investor which does not have a representative on the Advisory Committee the right to have a non-voting observer attend each meeting of the Advisory Committee. The Managing General Partner shall provide to any such observer notice of the time and place of any meeting of the Advisory Committee, and of any written consent being solicited from the Advisory Committee, in the same manner and at the same time as notice is sent

42

to the members of the Advisory Committee. The Managing General Partner shall also provide to any such observer copies of all notices, reports, minutes, consents and other documents at the time and in the manner as they are provided to the Advisory Committee. Any observer who attends any meetings of the Advisory Committee shall execute and comply with an agreement with the Partnership and the Managing General Partner containing such restrictions on the use and disclosure of confidential information and other matters as the Managing General Partner may reasonably request.

     SECTION 5.5 Management Team. The Managing General Partner shall, and hereby does, delegate authority and responsibility for the day-to-day management of the business of the Partnership to a President (the “President”), a Chief Financial Officer, a Chief Accounting Officer, a Senior Investment Manager, and an Asset Management Officer of the Partnership, and such other officers of the Partnership as the Managing General Partner may deem appropriate, with the establishment of any office and the appointment of any person to fill such office by the Managing General Partner being subject to the approval of the Management Board. Each officer of the Partnership shall be an employee of Hines or an Affiliate of Hines and shall, other than the President, report to the President. The officers of the Partnership, together with such other employees of Hines as may be assigned to conduct the business of the Partnership under the supervision of such officers are collectively referred to as the “Management Team.” The Managing General Partner shall promptly notify each other Partner of the identity of the officers of the Partnership and their offices and any changes thereto.

     SECTION 5.6 Management Rights of Limited Partners. Except as expressly provided in this Agreement, no Limited Partner shall have the right or power to participate in the management or affairs of the Partnership, nor shall any Limited Partner have the power to sign for or bind the Partnership. The exercise by any Limited Partner of any right conferred on Limited Partners by this Agreement shall not be construed to constitute participation by such Limited Partner in the control of the business of the Partnership so as to make such Limited Partner liable as a general partner for the debts and obligations of the Partnership for purposes of the Act.

     SECTION 5.7 Advisory Agreement. The Managing General Partner may from time to time cause additional Fund Entities to become party to the Advisory Agreement for the provision of advice and recommendations with respect to (to the extent applicable to such Fund Entity) the origination, investigation, structuring, finance, acquisition, monitoring and/or disposition of Investments by, and/or the structuring, organization, capitalization and/or financing of, such Fund Entity (subject to the consent of the other parties to the Advisory Agreement). The Managing General Partner shall remain liable to the Partnership for the performance of its obligations under this Agreement notwithstanding the delegation of any such obligations to the Investment Advisors pursuant to the Advisory Agreement. The Managing General Partner shall bear the costs of all services provided by the Investment Advisors under the Advisory Agreement; provided that the Investment Advisors shall be entitled to receive Asset Management Fees and Acquisition Fees as provided in the Advisory Agreement and Sections 7.2 and 7.3 of this Agreement.

     SECTION 5.8 Property Services Agreements. For each Property in which an Operating Company invests, a Fund Entity through which such Operating Company owns such Property

43

shall enter into a property services agreement (a “Property Services Agreement”) with Hines or an Affiliate of Hines (a “Property Manager”) substantially in the form attached hereto as Exhibit A (the “Property Services Agreement Form”) pursuant to which the Property Manager will provide property management, redevelopment and leasing services for such Property. By executing this Agreement, each Limited Partner approves the provisions of the Property Services Agreement Form and consents to the execution, delivery and performance by a Fund Entity of a Property Services Agreement substantially in such form with respect to each Property in which any Operating Company invests. Changes may be made to the Property Services Agreement as the Managing General Partner or the applicable Operating Company deems necessary or appropriate to accommodate the particular circumstances of each Property; provided that the Managing General Partner (i) must obtain the approval of the Non-Managing General Partner for any such changes, and (ii) shall not authorize any increase in the Property Services Fees payable to the Property Manager or any material increase in the risks or obligations to be borne by the Owner under any Property Services Agreement over those provided for in or contemplated by the Property Services Agreement Form, without the consent of the Advisory Committee pursuant to Section 5.4 hereof.

     SECTION 5.9 Asset Valuations; Determination of Current Unit Value; Cancellation of Units.

     (a) Commencing in the first full Fiscal Quarter following the termination of the Initial Offering Period, all Properties shall be appraised by an Appraiser on a rolling basis whereby approximately one-quarter of the Properties are appraised each Fiscal Quarter and each Property is appraised not less frequently than once in any twelve-month period. Each appraisal shall be updated quarterly by the Appraiser that conducted the appraisal (or, if such Appraiser is not available, such other Appraiser as the Managing General Partner may select), until the next full appraisal of such Property is conducted.

     (b) Any Person selected to appraise a Property (an “Appraiser”) shall be a Person qualified to appraise assets such as the Property in the market in which the Property is located. At least two Appraisers will be retained for any calendar year, with each Appraiser retained appraising approximately equal portions of the Partnership’s portfolio of Properties. Appraisers will be rotated or replaced so that no Property is appraised by the same Appraiser for more than three consecutive years. Each Appraiser will be selected by the Managing General Partner, subject to the approval of the Non-Managing General Partner and of the Advisory Committee pursuant to Section 5.4 hereof. The Managing General Partner may from time to time submit a list of Appraisers to the Advisory Committee. Any Appraiser on such list will be deemed approved by the Advisory Committee unless, within thirty days of the submission of such list to the Advisory Committee, the Advisory Committee votes to disapprove such Appraiser.

     (c) Each Fiscal Quarter the Managing General Partner shall establish the Current Market Value of each Property, the Current Total Equity Value, the Current Participation Interest Value, and the Current Unit Values derived from the Current Market Values, as so established, of all Properties. A hypothetical example calculation of Percentage Interests and Unit cancellations as contemplated by this Section 5.9 and the definition of Percentage Interest is provided at Schedule 5.9.

44

     (i) The “Current Market Value” of a Property shall be (x) the value established by the most recent appraisal of the Property conducted by an Appraiser in accordance with Sections 5.9(a) and (b), (y) if such Property has not been appraised since its acquisition by the Partnership, the value attributed to such Property upon its acquisition by the Partnership, or (z) such other value as the Managing General Partner determines is more appropriate than the value provided in clause (x) or (y) based on changes in the condition of the Property, the market in which it is located or other relevant factors since the date such Property was appraised or acquired, as applicable.

     (ii) The “Current Total Equity Value” as of any date shall equal the aggregate value of the interests of the Partnership in all Properties in which the Partnership has an indirect interest, determined by reference to the Current Market Value of such Properties as of such date, plus or minus such adjustments as the Managing General Partner reasonably determines are appropriate to reflect the assets and liabilities of the Partnership other than its interests in Properties as of such date.

     (iii) The “Current Participation Interest Value” for the entire Participation Interest as of any date shall equal the lesser of (a) the product of (i) the Percentage Interest attributable to the Participation Interest as of such date, multiplied by (ii) the Current Total Equity Value as of such date or (b) the aggregate amount that would be distributed in respect of the Participation Interest in accordance with Section 12.4(b) if the Partnership were to distribute an amount equal to the Current Total Equity Value among its Partners in accordance with Section 12.4(b) on such date. The Current Participation Interest Value of any portion of a Participation Interest shall be proportionate to the Current Participation Interest Value of the entire Participation Interest (e.g., 20% of the Participation Interest shall have a Current Participation Interest Value equal to 20% of the Current Participation Interest Value of the entire Participation Interest).

     (iv) The “Current Unit Value” of any Partnership Unit as of any date shall be the amount determined by dividing (x) the difference between the Current Total Equity Value and the Current Participation Interest Value of the entire Participation Interest as of such date, by (y) the total number of Partnership Units outstanding as of such date (including, if applicable, any other securities that are convertible into or exchangeable for Units as of such date).

     (d) At the end of each Fiscal Quarter ending after termination of the Initial Investment Period, a number of Partnership Units held by each Unaffiliated Limited Partner shall automatically, without any action by any party, be canceled, with the number of Units so cancelled being equal to (1) such Unaffiliated Limited Partner’s Applicable Percentage (as defined below) of the aggregate Unrecovered Capital of such Unaffiliated Limited Partner as of the end of such Fiscal Quarter, divided by the Current Unit Value as of the end of such Fiscal Quarter; plus, in the case of each Unaffiliated Limited Partner that has made Capital Contributions after the end of the Initial

45

Investment Period, (2)(A) the lesser of (x) the Total Property Base for the Fiscal Quarter just ended or (y) the Total Capital Base for the Fiscal Quarter just ended, multiplied by (B) a fraction whose numerator equals such Limited Partner’s Total Capital Base Share for the Fiscal Quarter just ended, and whose denominator equals the Total Capital Base for the Fiscal Quarter just ended divided by (C) the Current Unit Value of the Partnership as of the end of the Fiscal Quarter just ended.

     (i) The “Applicable Percentage” of each Unaffiliated Limited Partner shall be (i) as to SLR, 0.03125%, (ii) as to each Class A Major Investor, 0.09375%, (iii) as to each Class B Major Investor, 0.10625%, (iv) as to each Class C Major Investor, 0.1125%, (v) as to each Class D Major Investor, 0.11875%, and (vi) as to each other Unaffiliated Limited Partner, 0.125%.

     (ii) For purposes of effecting the computations set forth in this Section 5.9(d) for a particular Fiscal Quarter, (A) the Percentage Interest of a Limited Partner, and the Current Unit Value, as of the end of the Fiscal Quarter just ended shall be determined immediately prior to the cancellation of Partnership Units pursuant to this Section 5.9(d); and (B) the Current Unit Value as of the end of the Fiscal Quarter just ended shall be determined without taking into account any reduction therein which occurs as a result of the adjustment to Percentage Interests which occurs as of the end of such Fiscal Quarter pursuant to clauses (a) and (b) of the definition of Percentage Interest set forth in Section 1.1 hereof.

     (iii) The cancellation of Partnership Units pursuant to this Section 5.9(d) shall be determined and taken into account immediately after (A) the adjustments to Percentage Interests that occur pursuant to clauses (a) and (b) of the definition of Percentage Interest set forth in Section 1.1 hereof and (B) the calculations of Asset Management Fees and Acquisition Fees that occur pursuant to Sections 7.2 and 7.3, have been effected.

     (iv) The cancellation of Partnership Units pursuant to this Section 5.9(d) as of the end of any Fiscal Quarter shall become effective as of the beginning of the immediately following Fiscal Quarter.

     SECTION 5.10 Management of Operating Companies. Each Trust and any other Operating Company having a separate governing body shall be governed by a board of trustees or similar governing body whose membership includes all of the members of the Management Board. Each Trust, and any other Operating Company having its own officers or persons with similar functions, shall have a slate of officers which is headed by the President and whose other members are members of the Management Team. The Constituent Documents or other organizational documents of each Trust, and of any other Operating Company having a separate governing body, shall provide (i) the governing body thereof with oversight and approval rights with respect to the business and affairs of such Operating Company which are comparable to the oversight and approval rights which this Agreement provides to the Management Board with respect to the business and affairs of the Partnership, and (ii) SLR Designees with rights to participate in the management of such Operating Company which are comparable to the rights which this Agreement provides to SLR Designees to participate in the management of the

46

Partnership. The Managing General Partner shall, or shall cause the Partnership to, take such actions as may be permitted or required under the terms of the Constituent Documents of each Operating Company, and under the terms of any agreement entered into by the Partnership or the Managing General Partner in connection with the organization of such Operating Company, to ensure that the requirements of this Section 5.10 are met with respect to each Operating Company.

     SECTION 5.11 Non-Managing General Partner.

     (a) Hines REIT Properties, L.P., a Delaware limited partnership whose general partner is Hines Real Estate Investment Trust, Inc., a Maryland corporation, is a general partner of the Partnership and is designated the non-managing general partner of the Partnership (the “Non-Managing General Partner”). The Non-Managing General Partner shall be a “general partner” for all purposes under the Act, but shall have only those rights, duties, and obligations accorded to it by this Agreement and shall have no power to bind the Partnership or act on behalf of the Partnership independently of the Managing General Partner.

     (b) Notwithstanding any other provision of this Agreement, the Managing General Partner shall not take any of the following actions without the approval of the Non-Managing General Partner:

     (i) declare distributions to Partners in accordance with this Agreement;

     (ii) incur Indebtedness in the name of the Partnership or which is recourse to the Partnership;

     (iii) select any Appraiser;

     (iv) make any decision concerning the sale, transfer or disposition of any Investment in any third-party transaction; provided, that the value of such Investments is greater than 20% of the Gross Asset Value of the Partnership’s assets;

     (v) approve the merger or consolidation of the Partnership with an unrelated third party;

     (vi) make any amendments, revisions or modifications to Section 5.2 hereof or any other provisions of this Agreement with respect to investment policies or procedures;

     (vii) make any amendment to this Agreement which, under the terms of this Agreement, requires the consent of the Managing General Partner and of Limited Partners by a Majority LP Vote or higher vote;

     (viii) remove or appoint any Property Manager or approve renewals, amendments or modifications to any Property Services Agreement;

47

     (ix) remove or appoint any Investment Advisor that is an Affiliate of Hines, or approve renewals, amendments or modifications to any Advisory Agreement between the Partnership or any Operating Company, on the one hand, and any Investment Advisor that is an Affiliate of Hines, on the other;

     (x) sell Investments to Hines or any Affiliate of Hines or acquire Investments from Hines or any Affiliate of Hines;

     (xi) merge or consolidate the Partnership with any Affiliate of Hines; or

     (xii) any other matters as is specified in this Agreement.

ARTICLE VI

Exculpation and Indemnification

     SECTION 6.1 Exculpation of the General Partners. The Managing General Partner, the Non-Managing General Partner and their respective Affiliates, and the direct or indirect members, managers, partners, shareholders, officers, directors, employees, agents and legal representatives of the Managing General Partner, the Non-Managing General Partner and any such Affiliate, including any officer of the Partnership and any Investment Advisor (in each case, an “Indemnified Person”), shall not be liable to any Partner or the Partnership for any act or failure to act on behalf of the Partnership or of any Operating Company, except to the extent such act or failure to act constitutes gross negligence, recklessness, willful misconduct or bad faith on the part of the Indemnified Person, a knowing violation of law by the Indemnified Person or a material breach by the Indemnified Person of its obligations under this Agreement. Each of the Managing General Partner and the Non-Managing General Partner may exercise any of the powers granted to it hereunder and perform any of the duties imposed upon it hereunder either directly or by or through agents and shall not be responsible for any misconduct or negligence on the part of any such agent selected with reasonable care. Each of the Managing General Partner and the Non-Managing General Partner may rely, and shall be protected in acting or refraining from acting, and shall be deemed to have acted in good faith and without gross negligence or willful misconduct, upon any consent, approval or any other action taken by the Limited Partners or the Advisory Committee, and upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties. Each of the Managing General Partner and the Non-Managing General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers, architects, engineers, environmental consultants and other professional consultants and advisers selected by it with reasonable care, and shall be fully protected and justified and shall be deemed to have acted in good faith and without gross negligence or willful misconduct, in any action or inaction which is taken or omitted to be taken in reasonable reliance upon the advice or opinion of such Persons as to matters within such Persons’ professional or expert competence. Neither the Managing General Partner nor the Non-Managing General Partner shall be liable to the Partnership or the Partners for the failure to perform any obligation

48

that it cannot perform because the Partnership has insufficient funds to pay the cost and expense relative to such obligation.

     SECTION 6.2 Indemnification of Managing General Partner.

     (a) The Partnership, to the fullest extent permitted by law, shall indemnify and hold harmless each Indemnified Person from and against any loss, liability, expense, judgment, settlement cost, fees and related expenses (including reasonable attorneys’ fees and expenses), costs or damages arising out of or in connection with any act taken or omitted to be taken in respect of the affairs of the Partnership or of any Operating Company, unless such act or omission constitutes (i) for as long as the Non-Managing General Partner holds a Partnership Interest, in the case of the Managing General Partner and any other Indemnified Person that is an Affiliate of Hines or an officer or director of Hines or an Affiliate of Hines (other than an “independent director” of the general partner of the Non-Managing General Partner as defined in the Articles of Incorporation of the general partner of the Non-Managing General Partner), the misconduct or negligence of such person, or (ii) at all other times, and at all times in the case of any other Indemnified Person, the gross negligence, recklessness, willful misconduct or bad faith on the part of the Indemnified Person, a knowing violation of law by the Indemnified Person or a material breach by the Indemnified Person of its obligations under this Agreement. The termination of any action, suit or proceeding by settlement shall not, of itself, create a presumption that an Indemnified Person did not act in good faith or in a manner that was reasonably believed to be in, or not opposed to, the best interests of the Partnership or such Operating Company or was guilty of gross negligence, willful misconduct, bad faith or a knowing violation of law.

     (b) The Partnership, in the discretion of the Managing General Partner, may advance to any Indemnified Person reasonable attorneys’ fees and other costs and expenses incurred in connection with the defense of any action or proceeding which arises out of conduct which is the subject of the indemnification provided hereunder; provided, however, that (i) the Managing General Partner hereby agrees, and each other Indemnified Person shall agree as a condition to receiving any such advance, that in the event an Indemnified Person receives any advance, the Indemnified Person shall reimburse the Partnership for the advance to the extent that it is judicially determined, in a final, non-appealable judgment or binding arbitration, that the Indemnified Person was not entitled to indemnification under this Section 6.2 and (ii) neither the Managing General Partner nor any other Indemnified Person shall be entitled to any advance of costs and expenses in any action (either direct or derivative) brought against such Indemnified Person by Limited Partners pursuant to a Majority LP Vote, except to the extent that a court of competent jurisdiction issues a ruling (whether preliminary or final) substantially to the effect that the claim is one as to which it is likely that such Indemnified Person is entitled to the benefits of the exculpatory provisions set forth in Section 6.1. Notwithstanding anything to the contrary contained in this Section 6.2, neither the Managing General Partner nor any other Indemnified Person shall be entitled to indemnification for, or be indemnified by the Partnership against, any claim in any action (either direct or derivative) brought against such Indemnified Person by any Limited Partner if it is established, by a final non-appealable judgment, that such claim

49

was one as to which such Indemnified Person is not entitled to the benefits of the exculpatory provisions set forth in Section 6.1.

     SECTION 6.3 Treatment of Management Board, Advisory Committee, et al.. No member of the Management Board, the Management Team or the Advisory Committee (and no Limited Partner represented by any such Person) shall be a fiduciary of the Partnership or of any Partner. No member of the Advisory Committee and no SLR Designee shall be liable to any Partner or the Partnership for any reason (other than fraud or willful misconduct on the part of such person) including for any mistake in judgment, any action or inaction taken or omitted to be taken, or for any loss due to any mistake, action or inaction, and no Limited Partner represented by any such Person shall be liable to the Partnership or any Partner for the acts or omissions of such person in such capacity (or than as a result of fraud or willful misconduct). The participation by a person on the Management Board, the Management Team or the Advisory Committee shall not be construed to constitute participation by such person in the control of the business of the Partnership so as to make such person liable as a general partner for the debts and obligations of the Partnership for purposes of the Act. The participation by the representative of any Limited Partner on the Management Board or the Advisory Committee in the activities of the Management Board or Advisory Committee shall not be construed to constitute participation by such Limited Partner in the control of the business of the Partnership so as to make such Limited Partner liable as a general partner for the debts and obligations of the Partnership for purposes of the Act. No Limited Partner who has appointed a member of the Management Board or Advisory Committee shall be deemed to be an Affiliate of the Partnership or the Managing General Partner solely by reason of such appointment. In the absence of fraud or willful misconduct on the part of a member of the Advisory Committee or an SLR Designee, the Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless each such member of the Advisory Committee and each SLR Designee, and each Limited Partner represented by any such person, with respect to the Partnership (and their respective heirs and legal and personal representatives) who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including any action by or in the right of the Partnership or any of the Partners), by reason of any actions or omissions or alleged acts or omissions arising out of such Person’s activities in connection with serving on the Management Board or the Advisory Committee against losses, damages or expenses (including reasonable attorney’s fees, judgments, fines and amounts paid in settlement) actually incurred by such person in connection with such actions, suit or proceedings; provided that any person entitled to indemnification from the Partnership hereunder shall obtain the written consent of the Managing General Partner (which consent shall not be unreasonably withheld) prior to entering into any compromise or settlement which would result in an obligation of the Partnership to indemnify such person. The Partnership shall advance to any member of the Advisory Committee, any SLR Designee or any Limited Partner represented by any such person, reasonable attorneys’ fees and other costs and expenses incurred in connection with the defense of any action or proceeding which arises out of conduct which is the subject of the indemnification provided hereunder; provided, however, that each such Person must agree, as a condition to receiving any such advance, that in the event such person receives any advance, such Person shall reimburse the Partnership for the advance to the extent that it is judicially determined, in a final, non-appealable judgment or binding arbitration, that such person was not entitled to indemnification under this Section 6.3.

     SECTION 6.4 Limited Liability of Limited Partners. Except as provided by the Act or other applicable law and subject to the obligations to make Capital Contributions in accordance with this Agreement and its Subscription Agreement and to pay taxes to the extent provided in Section 11.4(c), no Limited Partner (including any Limited Partner that is an Affiliate of Hines or of SLR) shall have any personal liability whatsoever in its capacity as a Limited Partner, whether to the Partnership, to any of the Partners, or to the creditors of the Partnership, for the debts, liabilities, contracts, or other obligations of the Partnership or for any losses of the Partnership.

     SECTION 6.5 Other Activities of Limited Partners. Subject to Section 4.4 with respect to each Limited Partner that is an Affiliate of the Managing General Partner, each Limited Partner shall be entitled to and may have business interests and engage in activities in addition to those relating to the Partnership, including business interests and activities in direct competition with the Partnership and the entities in which the Partnership invests and may engage in transactions with, and provide services to, the Partnership or any such entity. Neither the Partnership, any other Partner nor any other Person shall have any rights by virtue of this Agreement in any business ventures of any Limited Partner.

ARTICLE VII

Expenses and Fees

     SECTION 7.1 Managing General Partner Expenses. The Partnership shall not have any salaried personnel. The Managing General Partner and its Affiliates, but not the Partnership or any Limited Partner, shall bear and be charged with the following costs and expenses of the Partnership’s activities: (a) any costs and expenses of providing to the Management Team the office space, facilities, supplies, and necessary ongoing overhead support services for the Partnership’s operations and (b) the compensation of the Management Team. The expenses that the Managing General Partner is obligated or elects to pay under this Section 7.1 are collectively referred to herein as the “Managing General Partner Expenses”. Notwithstanding anything herein to the contrary, no costs or expenses payable by the Owner of any Property under the terms of the Property Services Agreement entered into with respect to such Property shall be deemed Managing General Partner Expenses.

     SECTION 7.2 Asset Management Fee.

     (a) The Managing General Partner shall be paid a periodic management fee (the “Asset Management Fee”) as provided in this Section 7.2; provided that, to the extent the Managing General Partner assigns the right to receive the Asset Management Fee to the Investment Advisors pursuant to the Advisory Agreement, such fee shall be paid to the Investment Advisors as provided in the Advisory Agreement. The Asset Management Fee shall accrue quarterly in arrears and shall be payable, subject to the penultimate sentence of Section 7.2(b), on each Quarterly Payment Date. A portion of the Asset Management Fee accrued as of each Quarterly Payment Date shall be charged to each Unaffiliated Limited Partner in an amount equal to the product of (i) the Asset Management Fee Base of such Limited Partner on the first day of the Fiscal Quarter just ended, multiplied by (ii) (A) in the case of any Fiscal Quarter occurring during the Initial

51

Investment Period, 25%, or (B) in the case of any Fiscal Quarter occurring after the termination of the Initial Investment Period, 12.5%, multiplied by (iii) (A) for SLR, 0.25%, (B) for each Class A Major Investor, 0.75%, (C) for each Class B Major Investor, 0.85%, (D) for each Class C Major Investor, 0.90%, (E) for each Class D Major Investor, 0.95%, or (F) for each Unaffiliated Limited Partner that is not a Major Investor, 1.00%. The “Asset Management Fee Base” for any Unaffiliated Limited Partner shall be (A) prior to the termination of the Initial Investment Period, the Unrecovered Capital of such Unaffiliated Limited Partner plus such Unaffiliated Limited Partner’s Unfunded Commitment, and (B) after the termination of the Initial Investment Period, the Unrecovered Capital of such Unaffiliated Limited Partner. The Asset Management Fee shall be prorated for any partial quarter and for the quarter in which the termination of the Initial Investment Period occurs based on the number of days in such quarter or the number of days in such quarter before and after such termination occurs, as applicable.

     (b) The total Asset Management Fee accrued as of any Quarterly Payment Date shall be the sum of the amounts chargeable to each Unaffiliated Limited Partner as of such Quarterly Payment Date pursuant to Section 7.2(a). The Partnership shall deduct the amount chargeable to each Unaffiliated Limited Partner in respect of the Asset Management Fee from any amounts otherwise distributable to such Unaffiliated Limited Partner on or after the Quarterly Payment Date as of which the Asset Management Fee has accrued. If the amount accrued in respect of the Asset Management Fee and chargeable to an Unaffiliated Limited Partner as of any Quarterly Payment Date exceeds any amount otherwise distributable to such Unaffiliated Limited Partner, then payment of the Asset Management Fee to the Managing General Partner (or, if applicable, to the Investment Advisors) shall be deferred, without interest, to the extent of such excess until such time as additional amounts are otherwise available for distribution to such Unaffiliated Limited Partner. All amounts deducted from amounts otherwise distributable to an Unaffiliated Limited Partner and paid to the Managing General Partner (or the Investment Advisors) pursuant to this Section 7.2 shall be deemed to have been distributed to such Unaffiliated Limited Partner for all purposes under this Agreement.

     SECTION 7.3 Acquisition Fees.

     (a) The Managing General Partner shall be entitled to a fee (an “Acquisition Fee”), calculated as of the end of each Fiscal Quarter, with respect to all interests in any Properties acquired, directly or indirectly, by the Fund during or prior to such Fiscal Quarter, other than any Properties acquired from SLR or any of its Affiliates, in an amount equal to the lesser of (1) the Total Property Base for the Fiscal Quarter just ended or (2) the Total Capital Base for the Fiscal Quarter just ended. Such Acquisition Fee shall be paid to the Managing General Partner quarterly as provided in Section 7.3(b). If the Managing General Partner has assigned the right to receive Acquisition Fees to the Investment Advisors pursuant to the Advisory Agreement, such Acquisition Fees shall be payable to the Investment Advisors to the extent provided therein.

     (b) Each Unaffiliated Limited Partner shall be charged for a portion of the amount of Acquisition Fees payable to the Managing General Partner pursuant to Section 7.3(a) in an amount equal to (1) the amount of Acquisition Fee calculated under Section

52

7.3(a) for the Fiscal Quarter just ended, multiplied by (2) a fraction whose numerator equals such Limited Partner’s Total Capital Base Share for the Fiscal Quarter just ended, and whose denominator equals the Total Capital Base for the Fiscal Quarter just ended; provided, however, that the cumulative amount of all Acquisition Fees charged to any particular Unaffiliated Limited Partner as of any date shall not exceed the sum of (x) two percent (2%) of the total amount of Capital Contributions made by such Unaffiliated Limited Partner on or before the last day of the Initial Investment Period, plus (y) one percent (1%) of the total amount of Capital Contributions made by such Unaffiliated Limited Partner after the Initial Investment Period. The Partnership shall deduct the amount chargeable to each Unaffiliated Limited Partner in respect of Acquisition Fees from amounts otherwise distributable to such Unaffiliated Limited Partner and pay the amount so deducted to the Managing General Partner (or, if applicable, the Investment Advisors). All amounts deducted from amounts otherwise distributable to an Unaffiliated Limited Partner and paid to the Managing General Partner (or the Investment Advisors) pursuant to this Section 7.3 shall be deemed to have been distributed to such Unaffiliated Limited Partner for all purposes under this Agreement.

     (c) To the extent any Unaffiliated Limited Partner has been charged with the payment of Acquisition Fees pursuant to the provisions of Section 7.3 of the Fifth Restated Agreement in a manner that is inconsistent with the provisions of this Section 7.3, the Managing General Partner shall make appropriate adjustments to amounts withheld on account of Acquisition Fees from distributions otherwise payable to such Unaffiliated Limited Partners after the date of this Agreement to reconcile such inconsistencies.

     SECTION 7.4 Partnership Expenses.

     (a) The Partnership shall bear and be charged with the following costs and expenses of the Partnership paid or payable to third parties (and shall promptly reimburse the Managing General Partner or its Affiliates, as the case may be, to the extent that any of such costs and expenses are paid to third parties directly by such entities) (the “Partnership Expenses”):

     (i) fees and expenses for attorneys and accountants;

     (ii) all out-of-pocket costs and expenses, if any, incurred by the Partnership in developing, negotiating, structuring and organizing any Operating Company;

     (iv) expenses of liquidating the Partnership;

     (v) any taxes, fees or other governmental charges levied against the Partnership and all expenses incurred in connection with any tax audit, investigation, settlement or review of the Partnership; and

53

     (vi) the out-of-pocket expenses of the members of the Advisory Committee reimbursable under Section 5.4(f) to the extent such expenses are not reimbursed by an Operating Company.

     (b) Partnership Expenses may be allocated among the Partnership’s investments in a manner reasonably determined by the Managing General Partner. Partners may be required to make Capital Contributions to the extent of their Unfunded Commitments for the payment of such Partnership Expenses to the extent the Partnership does not have sufficient funds to pay such expenses.

     SECTION 7.5 Operating Company Expenses.

     (a) Each Operating Company shall bear and be charged with the following costs and expenses of such Operating Company paid or payable to third parties (and shall promptly reimburse the Managing General Partner or its Affiliates, as the case may be, to the extent that any of such costs and expenses are paid to third parties directly by such entities) (the “Operating Company Expenses”):

     (i) fees and expenses for attorneys and accountants;

     (ii) all reasonable out-of-pocket costs and expenses, if any, incurred by such Operating Company in acquiring, developing, negotiating, structuring, improving, and disposing of Investments or potential Investments, including any financing, legal, accounting, advisory and consulting expenses in connection therewith (to the extent not subject to any reimbursement of such costs and expenses by entities in which the Partnership invests or other third parties);

     (iii) brokerage commissions, custodial expenses and other investment costs actually incurred in connection with actual Investments;

     (iv) the costs of any litigation, D&O liability or other insurance and indemnification or extraordinary expense or liability relating to the affairs of such Operating Company (or, to the extent such expenses are paid by the Partnership pursuant to clause (iii) of Section 7.4(a), an allocable share of such expenses shall be charged to such Operating Company by the Partnership);

     (v) expenses of liquidating such Operating Company;

     (vi) any taxes, fees or other governmental charges levied against such Operating Company and all expenses incurred in connection with any tax audit, investigation, settlement or review of such Operating Company; and

     (vii) a reasonably allocable share (as determined by the Managing General Partner) of the out-of-pocket expenses of the members of the Advisory Committee paid by the Partnership pursuant to clause (vi) of Section 7.4(a).

     (b) Operating Company Expenses may be allocated among an Operating Company’s Investments in a manner reasonably determined by such Operating Company.

54

Partners may be required to make Capital Contributions to the extent of their Unfunded Commitments to enable the Partnership to provide funds to any Operating Company to pay Operating Company Expenses to the extent that such Operating Company does not have sufficient funds to pay such expenses.

     (c) Any amounts paid by the Partnership for or resulting from any instrument or other arrangement designed to hedge or reduce one or more risks associated with an Investment shall be considered a Partnership Expense relating to such Investment. Any distributions resulting from any such arrangements shall be treated as Operating Cash Flow from such Investment.

     (d) The Managing General Partner may withhold on a pro rata basis from any distributions amounts necessary to create, in its sole discretion, appropriate reserves for expenses (including Acquisition Fees) and liabilities, contingent or otherwise, of the Partnership, and may withhold from distributions otherwise payable to any Limited Partner amounts necessary to pay any unpaid amounts of any Asset Management Fee payable by such Limited Partner (in which case any such withheld distributions shall be deemed to have been made to such Limited Partner for all purposes under this Agreement).

     SECTION 7.6 Organization Expenses. The Partnership shall pay all out-of-pocket costs and expenses (including legal, accounting, tax, consulting and other professional fees and expenses and travel and entertainment expenses) incurred by the Partnership and the Managing General Partner and its Affiliates in connection with the structuring and organization of the Partnership, NY Trust, NY Trust II, US Core Trust and US Core Properties and the offering and sale of Partnership Units and, if applicable, securities issued by NY Trust, NY Trust II, US Core Trust, US Core Properties or any other Fund Entity, including expenses (other than placement fees) incurred in connection with the solicitation of Capital Commitments and the negotiation, execution and delivery of this Agreement and all other documents entered into in connection herewith (any such amounts, the “Organizational Expenses”). Notwithstanding the foregoing, the Partnership shall not be responsible for any Organizational Expenses incurred during the Initial Offering Period in excess of $2.5 million; any Organizational Expenses in excess of such amount incurred during the Initial Offering period shall be the responsibility of the Managing General Partner and its Affiliates. The Partnership may charge a reasonably allocable share of the Organizational Expenses it is required to pay to US Core Properties or other Operating Companies in which the Partnership has an interest, at the discretion of the Managing General Partner.

ARTICLE VIII

Capital Accounts; Allocations

     SECTION 8.1 Capital Accounts. A separate capital account (“Capital Account”) shall be maintained for each Partner.

     (a) To each Partner’s Capital Account there shall be added such Partner’s Capital Contributions, such Partner’s distributive share of Profits and any items in the

55

nature of income or gain which are specially allocated pursuant to Section 8.6 or Section 8.7, and the amount of any Partnership liabilities assumed by such Partner or which are secured by any Partnership property distributed to such Partner.

     (b) From each Partner’s Capital Account there shall be subtracted the amount of cash and the Gross Asset Value of any Partnership property distributed to such Partner pursuant to any provision of this Agreement, such Partner’s distributive share of Losses and any items in the nature of expenses or losses which are specially allocated pursuant to Section 8.6 or Section 8.7, and the amount of any liabilities of such Partner assumed by the Partnership or which are secured by any property contributed by such Partner to the Partnership.

     (c) In the event all or a portion of a Partnership Interest is Transferred in accordance with the terms of this Agreement, the Transferee shall succeed to the Capital Account of the Transferor to the extent it relates to the Transferred Partnership Interest.

     (d) In determining the amount of any liability for purposes of Sections 8.1(a) and (b), there shall be taken into account Code Section 752(c) and any other applicable provisions of the Code and Regulations.

     (e) This Section 8.1 and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner consistent with such Regulations. In the event the Managing General Partner shall determine that it is prudent to modify the manner in which the Capital Accounts, or any debits or credits thereto (including debits or credits relating to liabilities which are secured by contributed or distributed property or which are assumed by the Partnership, or the Partners) are computed in order to comply with such Regulations, the Managing General Partner may make such modification, provided that it is not likely to have a material effect on the amounts distributed to any Partner pursuant to Section 12.4 upon the liquidation of the Partnership. The Managing General Partner also shall (i) make any adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the Partners and the amount of Partnership capital reflected on the Partnership’s balance sheet, as computed for book purposes, in accordance with Regulations Section 1.704-1(b)(2)(iv)(g), and (ii) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Regulations Section 1.704-1(b).

     SECTION 8.2 Interest on and Return of Capital.

     (a) No Partner shall be entitled to any interest on its Capital Account or on its Capital Contributions to the Partnership.

     (b) Except as expressly provided for in this Agreement, no Partner shall have the right to demand or to receive the return of all or any part of its Capital Contributions to the Partnership and there shall be no priority of one Partner over another Partner as to the return of Capital Contributions or withdrawals or distributions of Profits and Losses.

56

No Partner shall have the right to demand or receive property other than cash in return for the contributions of such Partner to the Partnership.

     SECTION 8.3 Negative Capital Accounts. Upon the liquidation of the Partnership or the liquidation of the Participation Interest, the holder of the Participation Interest shall be required to pay to the Partnership any deficit or negative balance which may exist in its Capital Account at such time (determined after taking into account the allocations described in Article VIII or Section 12.4(b) for the year in which such liquidation or redemption occurs). Subject to the provisions of any guarantee or other written agreement between a Partner and the Partnership, no Partner shall otherwise be required to pay to the Partnership any deficit or negative balance which may exist in its Capital Account.

     SECTION 8.4 Allocation of Profits.

     (a) After giving effect to the allocations set forth in Sections 8.6 and 8.7, Profits for any fiscal year other than Capital Transactions Gains shall be allocated as follows:

     (i) first, Profits and, if necessary, items of gross profit and income, shall be allocated to the holder of the Participation Interest, until the cumulative amount of Profits and items of gross profit and income allocated to such holder pursuant to this Section 8.4(a) with respect to its Participation Interest equals the cumulative amount of distributions made to such holder pursuant to Section 9.1 hereof with respect to its Participation Interest; and

     (ii) thereafter, Profits shall be allocated among the Partners in proportion to the number of Partnership Units held by each such Partner.

     (b) After giving effect to the allocations set forth in Sections 8.6 and 8.7, Capital Transaction Gains shall be computed separately with respect to each property and each such Capital Transaction Gain shall be allocated among the Partners as follows:

     (i) Each Partner that is not an Unaffiliated Limited Partner shall be allocated Capital Transaction Gain in an amount equal to the Percentage Interest attributable to such Partner’s Partnership Units, multiplied by the total amount of such Capital Transaction Gain.

     (ii) The remaining amount of such Capital Transaction Gain shall be allocated among the holders of the Participation Interests and the Unaffiliated Limited Partners (A) first, in proportion to, and until each such Partner has been allocated Capital Transaction Gains pursuant to this clause (A) in an amount equal to, the minimum amounts necessary to cause the Capital Account balances of such Partners to be in proportion to the Percentage Interests of such Partners and (B) thereafter, among such Partners in proportion to their respective Percentage Interests.

     (c) In the event that the Partnership issues or redeems Partnership Interests pursuant to Article III hereof, the Managing General Partner shall make such revisions to

57

the method of allocating Profits in this Section 8.4 as it determines are necessary to reflect the terms of the issuance or redemption of Partnership Interests, including such revisions as are needed to ensure that such allocations (i) will comply with the terms of Regulation Sections 1.704-1 and -2, (ii) will properly reflect the varying interests of the Partners in the Partnership, and (iii) will cause the Capital Accounts of the Partners in respect of Partnership Interests held by them to be in the ratios in which the Partners are entitled to receive distributions with respect to their Partnership Interests pursuant to Article IX hereof.

     SECTION 8.5 Allocations of Losses.

     (a) After giving effect to the special allocations set forth in Sections 8.6 and 8.7, Losses (including Capital Transaction Losses, which shall be computed and allocated separately with respect to each property) shall be allocated among the Partners as follows:

     (i) Each Partner that is not an Unaffiliated Limited Partner shall be allocated Losses in an amount equal to the Percentage Interest attributable to such Partner’s Partnership Units, multiplied by the total amount of such Losses.

     (ii) The remaining portion of such Losses shall be allocated among the holders of the Participation Interests and the Unaffiliated Limited Partners (A) first, in proportion to, and until each such Partner has been allocated Losses pursuant to this clause (A) in an amount equal to, the minimum amounts necessary to cause the Capital Account balances of such Partners to be in proportion to the Percentage Interests of such Partners and (B) thereafter, among such Partners in proportion to their respective Percentage Interests.

     (b) The Losses allocated pursuant to Section 8.5(a) shall not exceed the maximum amount of Losses that can be so allocated without causing any Partner to have an Adjusted Capital Account Deficit at the end of any Fiscal Year. Subject to the limitations in the preceding sentence, all Losses in excess of the limitations set forth in this Section 8.5(b) shall be allocated pro rata to the other Partners in proportion to the number of Units held by each Partner.

     (c) In the event that the Partnership issues or redeems Partnership Interests pursuant to Article III hereof, the Managing General Partner shall make such revisions to the method of allocating Losses in this Section 8.5 as it determines are necessary to reflect the terms of the issuance or redemption of Partnership Interests, including such revisions as are needed to ensure that such allocations (i) will comply with the terms of Regulation Section 1.704-1 and -2, (ii) will properly reflect the varying interests of the Partners in the Partnership and (iii) will cause the Capital Accounts of the Partners in respect of Partnership Interests held by them to be in the ratios in which the Partners are entitled to receive distributions with respect to their Partnership Interests pursuant to Article IX hereof.

58

     SECTION 8.6 Special Allocations. The following special allocations shall be made in the following order:

     (a) Except as otherwise provided in Regulations Section 1.704-2(f), and notwithstanding any other provision of this Article VIII, if there is a net decrease in Partnership Minimum Gain during any Fiscal Year, each Partner shall be specially allocated items of Partnership income and gain for such Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such Partner’s share of the net decrease in Partnership Minimum Gain, determined in accordance with Regulations Section 1.704-2(g). The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 8.6(a) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

     (b) Except as otherwise provided in Regulations Section 1.704-2(i)(4), and notwithstanding any other provision of this Article VIII, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any Partnership Fiscal Year, each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Partnership income and gain for such Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such Partner’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(4). The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(i)(2). This Section 8.6(b) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

     (c) In the event any Partner unexpectedly receives any adjustments, allocations, or distributions described in Regulations Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specially allocated to each such Partner in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Partner as quickly as possible, provided that an allocation pursuant to this Section 8.6(c) shall be made only if and to the extent that such Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article VIII have been tentatively made, as if this Section 8.6(c) were not in this Agreement.

     (d) In the event any Partner has an Adjusted Capital Account Deficit at the end of any Partnership Fiscal Year, each such Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 8.6(d) shall be made only if and to the extent that such Partner would have a deficit Capital Account after all other allocations provided for in this Article VIII have been made as if Section 8.6(c) hereof and this Section 8.6(d) were not in this Agreement.

59

     (e) Partnership Nonrecourse Deductions for any Fiscal Year shall be allocated among the Partners in proportion to their respective Percentage Interests.

     (f) Any Partner Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Partner who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable, in accordance with Regulations Section 1.704-2(i)(1).

     (g) To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) is required, pursuant to Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Partner in complete liquidation of its interest in the Partnership, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specifically allocated to the Partner to whom such distribution was made.

     SECTION 8.7 Curative Allocations. The allocations set forth in Section 8.5(b) and Sections 8.6(a), (b), (c) (d), (e) and (g) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations under Code Section 704(b). It is the intent of the Partners that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Partnership income, gain, loss, or deduction pursuant to this Section 8.7. Therefore, notwithstanding any other provision of this Article 8 (other than the Regulatory Allocations), the Managing General Partner shall make such offsetting special allocations of Partnership income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not part of the Agreement and all Partnership items were allocated pursuant to Section 8.4(a)(ii) and 8.5(a). In exercising its discretion under this Section 8.7, the Managing General Partner shall take into account future Regulatory Allocations under Sections 8.6(a) and (b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Sections 8.6(e) and (f).

     SECTION 8.8 Tax Allocations: Code Section 704(c).

     (a) Income, gain, loss, and deduction with respect to any property contributed to the capital of the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such property to the Partnership for federal income tax purposes and its initial Gross Asset Value in accordance with any permissible method or methods under Code Section 704(c) and the Regulations thereunder.

     (b) In the event the Gross Asset Value of any Partnership asset is adjusted pursuant to the definition of “Gross Asset Value”, subsequent allocations of income, gain, loss and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross

60

Asset Value in the same manner or manners permitted under Code Section 704(c) and the Regulations thereunder.

     (c) Any elections or other decisions relating to the allocations provided under this Article VIII shall be made by the Managing General Partner using any permissible manner under the Code or the Regulations that the Managing General Partner may elect in its sole discretion. Allocations pursuant to this Section 8.8 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Partner’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision in this Agreement.

ARTICLE IX

Distributions

     SECTION 9.1 Operating Cash Flow. As used in this Agreement, “Operating Cash Flow” shall mean and be defined, for any fiscal period, as all cash receipts of the Partnership from whatever source (but excluding Capital Cash Flow and excluding the proceeds of any Capital Contributions to the Partnership) during such period in question in excess of all items of Partnership expense (other than non-cash expenses such as depreciation) and other cash needs of the Partnership, including, without limitation, amounts paid by the Partnership as principal on debts and advances, during such period, capital expenditures and any reserves (as determined by the Managing General Partner) established or increased during such period. Operating Cash Flow shall be distributed to or for the benefit of the Partners of record as of the applicable record date not less frequently than quarterly, and shall be allocated among the Partners as follows:

     (a) A portion of such distribution, equal to the sum of the Percentage Interests attributable to the Participation Interests multiplied by the total amount of such distribution, shall be distributed to the holders of the Participation Interests in proportion to their respective Percentage Interests.

     (b) The remaining portion of such distribution shall be distributed among the Partners in proportion to the number of Partnership Units held by each such Partner.

A hypothetical example calculation of Operating Cash Flow distributions to holders of Units and Participation Interests based on certain stated assumptions is set forth at Schedule 9.1.

     SECTION 9.2 Capital Cash Flow. As used in this Agreement, “Capital Cash Flow” shall mean and be defined as collectively (a) gross proceeds realized in connection with the sale of any assets of the Partnership, (b) gross financing or refinancing proceeds, (c) gross condemnation proceeds (excluding condemnation proceeds applied to restoration of remaining property), (d) gross insurance proceeds (excluding rental insurance proceeds or insurance proceeds applied to restoration of property), (e) return from an Operating Company of capital contributed or advanced to such Operating Company by the Partnership, and (f) distributions by an Operating Company of capital contributed or advanced to such Operating Company, less (a) closing costs, (b) the cost to discharge any Partnership financing encumbering or otherwise associated with the asset(s) in question, (c) the establishment of reserves (as determined by the Managing General

61

Partner, and which may include cash held for future acquisitions), and (d) other expenses of the Partnership then due and owing. Subject to Section 9.3, Capital Cash Flow shall be distributed to or for the benefit of the Partners of record as of the applicable record date not less frequently than quarterly and, subject to Section 12.4(b), shall be allocated among the Partners as follows:

     (a) A portion of such distribution, equal to the sum of the Percentage Interests attributable to the Participation Interests multiplied by the total amount of such distribution, shall be distributed to the holders of the Participation Interests in proportion to their respective Percentage Interests.

     (b) The remaining portion of such distribution shall be distributed among the Partners in proportion to the number of Partnership Units held by each such Partner.

A hypothetical example calculation of Capital Cash Flow distributions to holders of Units and Participation Interests based on certain stated assumptions is set forth at Schedule 9.2.

     SECTION 9.3 Reinvestment of Capital Cash Flow. The Managing General Partner may, in its discretion, apply all or part of Capital Cash Flow to provide funds to Operating Companies to make new Investments or repay Indebtedness, make additional investments in existing Investments or to fund the redemption of interests in the Fund pursuant to the terms of this Agreement or the Constituent Documents of any Fund Entity.

     SECTION 9.4 Right to Limit Distributions. The right of any Partner to receive distributions of any nature pursuant to the terms of this Agreement shall be subject to Sections 7.2, 7.3 and 9.3, any other applicable provisions of this Agreement and the terms of any agreement between such Partner and the Partnership limiting, restricting or providing rights of set-off with respect to such distributions.

     SECTION 9.5 Limitations on Distribution Rights. Notwithstanding any provision to the contrary contained in this Agreement, the Partnership, and the Managing General Partner on behalf of the Partnership, shall not be required to make a distribution to a Partner on account of its interest in the Partnership if such distribution would violate the Act or any other applicable law. The Partnership will not make any distribution in kind without the approval of the Limited Partners by a Majority LP Vote, except for distributions of publicly-traded securities made with the Advisory Committee’s approval pursuant to Section 5.4 hereof.

     SECTION 9.6 Tax Distributions. The Managing General Partner and the Non-Managing General Partner shall use their best efforts to cause the Partnership to make distributions of Operating Cash Flow and Capital Cash Flow to the Partners pursuant to this Article IX for each taxable year in an amount that is not less than the product of the maximum marginal U.S. federal income tax rate applicable to corporations for such taxable year, multiplied by the Partnership’s net taxable income and gain for such taxable year.

Transfers; Withdrawals and Defaults

     SECTION 10.1 Voluntary Transfer of Managing General Partner Interest. Without the consent of the Fund Investors by a Super Majority Fund Vote, the Managing General Partner shall not have the right to assign or otherwise transfer its interest as a general partner of the Partnership designated the Managing General Partner (but may pledge its interest in connection with any Partnership borrowing) other than to another Hines Controlled Entity, and the Managing General Partner shall not have the right to withdraw from the Partnership; provided that without the consent of the Limited Partners or any other Fund Investors, the Managing General Partner may be reconstituted as or converted into a corporation, limited partnership or other form of entity (any such reconstituted or converted entity being deemed to be the Managing General Partner for all purposes hereof) by merger, consolidation or otherwise, so long as (i) the Managing General Partner continues to be a Hines Controlled Entity; (ii) such reconstitution, conversion or transfer does not have adverse tax or legal consequences for the Limited Partners or the Partnership; (iii) the Managing General Partner has notified the Limited Partners of such transaction at least thirty days prior to the effective date of such transaction; and (iv) the Limited Partners shall not have made a reasonable objection to such transaction prior to the effective date of such transaction by a Majority LP Vote. No such assignment or other transfer of all of the Managing General Partner’s interest as a general partner of the Partnership shall be effective until its assignee or transferee has been substituted in its place as a general partner of the Partnership designated the Managing General Partner. Any such substitute general partner shall be admitted as a general partner of the Partnership designated the Managing General Partner upon its execution and delivery of this Agreement as Managing General Partner, and immediately thereafter the replaced general partner shall withdraw as a general partner of the Partnership.

     SECTION 10.2 Removal of Managing General Partner.

     (a) The Managing General Partner may be removed by a Majority Fund Vote if a Finding of Cause shall have been made and shall have become effective and shall not have been withdrawn or rescinded in accordance with the provisions of this Section 10.2(a). For purposes of this Agreement, the term “Finding of Cause” means a written determination by Fund Investors by a Majority Fund Vote that the Managing General Partner has committed willful malfeasance in the performance of any of its material duties under this Agreement or has committed gross negligence, willful misconduct or fraud which is the primary cause of a material adverse effect on the Partnership and has continued without being substantially cured for a period of at least thirty Business Days after the date upon which written notice shall have been given to the Managing General Partner by Fund Investors pursuant to a Majority Fund Vote stating that they believe such willful malfeasance, gross negligence, willful misconduct or fraud has occurred and identifying with reasonable particularity the actions constituting or resulting in such willful malfeasance, gross negligence, willful misconduct or fraud; provided, however, that the Managing General Partner shall have the right to dispute any determination that such willful malfeasance, gross negligence, willful misconduct or fraud has occurred or is continuing or that such willful malfeasance, gross negligence, willful misconduct or fraud

63

is the primary cause of a material adverse effect on the Partnership and, if the Managing General Partner does so, a Finding of Cause shall not become effective until the date upon which the dispute with respect to such determination has been resolved (whether by agreement between the Managing General Partner and Fund Investors by a Majority Fund Vote or as a result of a judgment or award in any judicial proceeding). Any determination of or by the Fund Investors, and the effectiveness, of any Finding of Cause may be rescinded or withdrawn at any time by the Fund Investors by a Majority Fund Vote.

     (b) At any time after the Initial Investment Period, the Managing General Partner may be removed by a 75% Majority Fund Vote with or without a Finding of Cause by causing the Partnership to redeem all Partnership Interests held by the Managing General Partner and its Affiliates (including the Hines Limited Partner) by issuance of a promissory note with a term of not more than three years, bearing interest at the Prime Rate, and with a principal amount equal to the sum of the Current Unit Value of all Units and the Current Participation Interest Value of the Participation Interest held by the Managing General Partner and its Affiliates (including the Hines Limited Partner).

     (c) No removal of the Managing General Partner pursuant to this Section 10.2 shall be effective until a successor general partner designated the Managing General Partner has been admitted to the Partnership in place of the removed Managing General Partner. Upon such admittance to the Partnership, such successor Managing General Partner will be entitled to appoint members of the Management Board in substitution of those appointed by the Managing General Partner immediately prior to such removal of the Managing General Partner.

     SECTION 10.3 Transfers of Partnership Interests by Hines Partners.

     (a) Subject to Sections 10.1 and 10.2, each of the Managing General Partner and the Hines Limited Partner may Transfer part or all of the Partnership Units and Participation Interests held by it in accordance with the provisions of this Agreement; provided that, (i) unless otherwise approved by the Limited Partners pursuant to a Super Majority LP Vote, no such Transfer shall be permitted that would result in the Hines Capital Requirement failing to be met, (ii) if the Non-Managing General Partner is the Transferee of such Partnership Units or Participation Interests, it shall take them only in respect of its interest in the Partnership as the Non-Managing General Partner, and (iii) any Transferee other than the Non-Managing General Partner of any such Partnership Units or Participation Interest shall take them only in respect of a limited partner interest in the Partnership and not as a general partner, except, in the case of clauses (ii) and (iii) above, to the extent the Transfer of a general partner interest to a Transferee designated the Managing General Partner has been approved in accordance with Section 10.1.

     (b) Unless otherwise approved by Fund Investors by a Super Majority Fund Vote, the Managing General Partner shall ensure that the Managing General Partner is at all times a Hines Controlled Entity and that Hines Controlled Entities and the Hines Group, in the aggregate, own (directly or indirectly) a majority of the equity in the Managing General Partner.

64

     SECTION 10.4 Transfers of Units by Partners Other than Hines Partners. Any Partner other than the Managing General Partner and the Hines Limited Partner may Transfer any Units and all or part of any Participation Interest held by it at any time, subject only to the provisions of Section 10.5. Any such Partner that Transfers all or any part of the Units or Participation Interest held by it shall pay all reasonable expenses, including attorneys’ fees, incurred by the Partnership or the Managing General Partner in connection with such Transfer.

     SECTION 10.5 Conditions to Transfer.

     (a) No Transfer of part or all of any Partnership Interest shall be made unless in the opinion of responsible counsel (which may be counsel for the Partnership), which opinion of counsel shall be reasonably satisfactory to the Managing General Partner and which opinion may be waived, in whole or in part, in the sole and absolute discretion of the Managing General Partner:

     (i) such Transfer would not violate the Securities Act or any state securities or “Blue Sky” laws or the securities laws of any other jurisdiction applicable to the Partnership or the Partnership Interests to be assigned or transferred;

     (ii) such Transfer would not cause the Partnership to lose its status as a partnership for U.S. federal income tax purposes or cause the Partnership to become subject to the Investment Company Act;

     (iii) such Transfer would not cause the Partnership to be treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code and the Regulations promulgated thereunder;

     (iv) such Transfer would not cause (A) all or any portion of the assets of the Partnership (1) to constitute “plan assets” (under ERISA, the Code or the applicable provisions of any Similar Law) of any existing or contemplated investor, or (2) to be subject to the provisions of ERISA, the Code or any applicable Similar Law, or (B) the Managing General Partner to become a fiduciary with respect to any existing or contemplated investor, pursuant to ERISA or the applicable provisions of any Similar Law, or otherwise;

     (v) such Transfer would not cause a termination of the Partnership under Code Section 708; and

     (vi) such Transfer would not violate or result in a violation of the Constituent Documents of any Operating Company in which the Partnership has a direct or indirect interest.

     (b) No Transfer of a Partnership Interest, in whole or in part, may be made if, in the opinion of legal counsel to the Partnership,

     (i) such Transfer would result in the Partnership’s being treated as an association taxable as a corporation; or

65

     (ii) such Transfer would result in the Partnership no longer qualifying for the Private Placement PTP Exemption.

     (c) If, and beginning with the first day of the first taxable year in which, the Partnership no longer qualifies for the Private Placement PTP Exemption, no Transfer of a Partnership Interest, in whole or in part, may be made unless such Transfer constitutes a Private Transfer.

     (d) Any purported Transfer attempted in contravention of any of the provisions of this Section 10.5 shall be void ab initio and ineffectual and shall not be binding upon, or recognized by, the Managing General Partner or the Partnership. Prior to the consummation of any Transfer by any Partner, such Partner shall deliver to the Managing General Partner such legal opinions, certificates and other documents as the Managing General Partner shall reasonably request in connection with such Transfer.

     (e) Redemptions of Partnership Interests pursuant to Sections 3.8, 3.9 or 3.10 shall not be considered Transfers for purposes of this Section 10.5.

     SECTION 10.6 Admissions and Withdrawals Generally, Nature of Partnership Interest.

     (a) Except as expressly provided in this Agreement, no Partner shall have the right to withdraw from the Partnership or to withdraw any part of its Capital Account and no additional Partner may be admitted to the Partnership. The Non-Managing General Partner and any Limited Partner shall be deemed to have withdrawn as a Partner of the Partnership at such time as such Person has disposed of all Partnership Units and Participation Interests held by such Person in a manner permitted by the terms of this Agreement. Each new Partner shall be admitted as a Partner upon the execution by or on behalf of it of an agreement pursuant to which it becomes bound by the terms of this Agreement and acceptance thereof by the Managing General Partner on behalf of the Partnership. The names and addresses of all Persons admitted as Partners and their status as Managing General Partner, Non-Managing General Partner or a Limited Partner shall be maintained in the records of the Partnership.

     (b) The entire Partnership Interest of each of the Managing General Partner and the Non-Managing General Partner is a general partner interest, and all Partnership Units or Participation Interest held or hereafter acquired by either such Partner, whether acquired from the Partnership or from any other Partner, is and shall be held in respect of its general partner interest, with the Managing General Partner having those rights and obligations provided to the Managing General Partner by this Agreement and the Non-Managing General Partner having those rights and obligations provided to the Non-Managing General Partner by this Agreement. The entire Partnership Interest of each Limited Partner is a limited partner interest, and all Partnership Units or Participation Interest held or hereafter acquired by a Limited Partner, whether acquired from the Partnership, the Managing General Partner, the Non-Managing General Partner, or any other Limited Partner, shall be held in respect of its limited partner interest, with such Limited Partner having the rights and obligations provided to a Limited Partner under this Agreement. As provided in Section 5, any Partnership Interest represented by a Class N

66

Partnership Unit shall be a non-voting interest regardless of who holds such Class N Partnership Unit.

     SECTION 10.7 Required/Elective Withdrawals. The Managing General Partner may require a Limited Partner to withdraw from the Partnership if (i) in the reasonable judgment of the Managing General Partner based upon an opinion of counsel to the Partnership, by virtue of that Limited Partner’s Partnership Interest, the Partnership or any Partner is reasonably likely to be subject to any requirement to register under the Investment Company Act, or (ii) in the reasonable judgment of the Managing General Partner, a significant delay, extraordinary expense or material adverse effect on the Partnership or any of its Affiliates, any Fund Entity or any prospective investment is likely to result from the retention by such Limited Partner of a Partnership Interest. Notice of any such withdrawal shall be given to all Limited Partners as well as a copy of the opinion of counsel referred to above in the case of a withdrawal pursuant to clause (i) above. Withdrawals pursuant to this Section 10.7 will be effected by the Partnership’s redeeming the Units held by such Limited Partner at the Current Unit Value, with the redemption price being payable by a promissory note having a term of not more than three years and bearing interest at the Prime Rate.

     SECTION 10.8 Defaulting Partner.

     (a) Any Partner that fails to make, when due, any portion of the Capital Contributions required to be made by such Partner pursuant to this Agreement and the Subscription Agreement to which such Partner is a party may, in the discretion of the Managing General Partner, be charged an additional amount on the unpaid balance of any such Capital Contribution at the Default Rate from the date such balance was due and payable through the date full payment for such balance is actually made, and to the extent such additional amount is not otherwise paid such additional amount may be deducted from any distribution otherwise payable to such Partner.

     (b) If any Partner fails to make, when due, any portion of the Capital Contribution required to be contributed by such Partner pursuant to this Agreement and the Subscription Agreement to which such Partner is a party, then the Partnership shall promptly provide written notice of such failure to such Partner. If such Partner fails to make such Capital Contribution within five Business Days after receipt of such notice, then (i) such Partner shall be deemed a “Defaulting Partner” and the following Sections 10.8(c) through (h) shall apply.

     (c) The Managing General Partner shall have the right to determine, in its sole discretion, that whenever the vote, consent or decision of a Partner or of the Partners is required or permitted pursuant to this Agreement, except as required by the Act, any Defaulting Partner shall not be entitled to participate in such vote or consent, or to make such decision, and such vote, consent or decision shall be tabulated or made as if such Defaulting Partner were not a Partner.

     (d) The Managing General Partner shall have the right in its sole discretion to either (i)(A) determine that a Defaulting Partner shall forfeit to the non-defaulting Partners as recompense for damages suffered, and the Partnership shall withhold (for the

67

account of such other Partners), all distributions of Operating Cash Flow and Capital Cash Flow and liquidating distributions that such Defaulting Partner would otherwise receive, and (B) effect a forfeiture by such Partner of 20% of its aggregate Partnership Interest (including 20% of its Capital Account balance); or (ii) upon delivery of written notice to the Defaulting Partner, cause the Defaulting Partner to transfer all of its interest in the Partnership to one or more other Partners (or any other Person or Persons to the extent not purchased by any Partner) selected by the Managing General Partner in its sole discretion, which have agreed to purchase such interest at a transfer price equal to at least 80% of such Defaulting Partner’s Capital Account balance.

     (e) In the event that a Partner defaults in making all or any portion of a Capital Contribution to the Partnership, the Managing General Partner may require all of the non-defaulting Partners to increase their Capital Contributions by an aggregate amount equal to the Capital Contribution of the Defaulting Partner on which it defaulted; provided that no Partner will be required to contribute any amounts in excess of its Unfunded Commitment without such Partner’s consent. If the Managing General Partner elects to require such increase, the Managing General Partner shall deliver to each non-defaulting Partner written notice of such default as promptly as practicable after its occurrence and, thereafter, with respect to each Investment, the Managing General Partner shall as promptly as practicable deliver to each such non-defaulting Partner a Capital Call Notice in respect of the Capital Contribution which the Defaulting Partner failed to make.

Subject to the provisos set forth above in this Section 10.8(e), such Capital Call Notice shall (i) call for a Capital Contribution by each such non-defaulting Partner in an amount equal to the amount of such non-defaulting Partner’s pro rata share of such additional Capital Contribution, based on the Unfunded Commitments of the Partners, and (ii) specify a Payment Date for such Capital Contribution, which date shall be at least ten calendar days from the date of delivery of such Capital Call Notice by the Managing General Partner. If any Partner is not required to make a Capital Contribution in accordance with this Section 10.8(e) because such Capital Contribution would be in excess of such Partner’s Unfunded Commitment, then, subject to the provisos set forth in this Section 10.8(e), the Managing General Partner shall send to each other Partner which is not subject to such constraint a Capital Call Notice providing the amount of any additional Capital Contribution which such other Partner shall be required to make as a result of such excess not being funded by the Partner which is subject to such constraint, which amount shall bear the same ratio to the aggregate of the additional amounts payable by all such other non-defaulting Partners as such other Partner’s Unfunded Commitment bears to the Unfunded Commitments of all such other non-defaulting Partners. The provisions of this Section 10.8(e) shall operate successively until either all Partners are subject to such constraint or the full amount of the defaulted Capital Contribution of the Defaulting Partner has been provided for.

     (f) No right, power or remedy conferred upon the Managing General Partner in this Section 10.8 shall be exclusive, and each such right, power or remedy shall be cumulative and in addition to every other right, power or remedy whether conferred in this Section 10.8 or now or hereafter available at law or in equity or by statute or otherwise. No course of dealing between the Managing General Partner and any Defaulting Partner and no delay in exercising any right, power or remedy conferred in

68

this Section 10.8 or now or hereafter existing at law or in equity or by statute or otherwise shall operate as a waiver or otherwise prejudice any such right, power or remedy.

     (g) Each Partner acknowledges by its execution hereof that it has been admitted to the Partnership in reliance upon its agreements under this Agreement and in its Subscription Agreement, that the Managing General Partner and the Partnership may have no adequate remedy at law for a breach of such agreements and that damages resulting from a breach of such agreements may be impossible to ascertain at the time hereof or of such breach.

     (h) For purposes of this Section 10.8, if any Defaulting Partner is any Entity the equity owners of which consist of two or more unaffiliated investors, the Managing General Partner may, in its sole discretion, treat the owner of such entity that was responsible for such default (and not such entity or any general partner, managing member or other controlling person of such entity) as the Defaulting Partner and may invoke the rights, powers and remedies specified herein separately with respect to such owner, and hold such owner solely responsible for such default.

Partnership Administration

     SECTION 11.1 Books and Records. The Managing General Partner shall keep or cause to be kept complete and appropriate records and books of account for the Partnership. Except as otherwise expressly provided herein, such books and records shall be maintained on a basis which allows the proper preparation of the Partnership’s financial statements and tax returns. The books and records shall be maintained at the principal office of the Partnership. Any Partner or its duly authorized representatives shall be permitted to inspect the books and records of the Partnership for any proper purpose and make copies thereof consistent with reasonable confidentiality restrictions established by the Managing General Partner at any reasonable time during normal business hours.

     SECTION 11.2 Partnership Auditor. The Managing General Partner shall cause the books and records of the Partnership to be audited as of the end of each Fiscal Year by an independent certified public accounting firm of national or international standing and reputation equivalent to the existing “big four” firms selected by the Managing General Partner (the firm so selected, the “Partnership Auditor”). As of the date of this Agreement, the Partnership Auditor is Deloitte & Touche LLP.

     SECTION 11.3 Filing of Tax Returns. The Managing General Partner shall prepare and file, or cause the accountants of the Partnership to prepare and file, a U.S. federal information tax return in compliance with Section 6031 of the Code and any required state, local and foreign income tax and information returns for each tax year of the Partnership.

     SECTION 11.4 Tax Matters.

     (a) The Managing General Partner shall be designated on the Partnership’s annual U.S. federal information tax return as the “tax matters partner” of the Partnership

69

(the “Tax Matters Partner”) as provided in Section 6231(a)(7) of the Code. If the Partnership is the subject of an income tax audit by any federal, state, local or foreign authority, then to the extent the Partnership is treated as an entity for purposes of the audit, including administrative settlement and judicial review, the Tax Matters Partner shall be authorized to act for, and its decision shall be final and binding upon, the Partnership and each Partner. All expenses incurred in connection with any audit, investigation, settlement or review shall be borne by the Partnership.

     (b) The Managing General Partner shall take such steps as are necessary to ensure that the Partnership is taxed as a partnership under the Code. Subject to the preceding sentence, the Managing General Partner shall have the exclusive right to make any determination whether the Partnership shall make available elections (including any election pursuant to Code Section 754 to adjust the tax basis of Partnership assets) for federal, state, or local tax purposes, and the Managing General Partner shall be absolved from all liability and other consequences from its making or failing to make any such election. All decisions and other matters concerning the computation and allocation or tax items and attributes which are not otherwise specifically provided for by the terms of this Agreement shall be determined by the Managing General Partner, and the Managing General Partner shall be absolved from all liability and other consequences from any such decisions which are made in good faith.

     (c) The Managing General Partner shall take all such actions as are reasonably necessary for the Partnership to comply with any withholding or comparable requirements under federal, state, local and foreign law and shall remit any amounts withheld to, and file required forms with, the applicable taxing jurisdictions. All amounts withheld from distributions shall be treated as having been distributed to the Partner with respect to whom the withholding was made. Any amounts that are required to be withheld by the Partnership with respect to a Partner which are in excess or in advance of distributions to such Partnership shall be paid over by such Partner to the Partnership and shall not reduce the Unfunded Commitment or increase the Funded Commitment of such Partner. Each Partner agrees to furnish the Partnership with such representations and forms as the Managing General Partner shall reasonably request to assist in complying with the Partnership’s withholding obligations. A Partner subject to withholding shall pay to or reimburse the Partnership for taxes, related interest and penalties, and all other costs and expenses incurred by the Partnership in connection with such withholding obligation, except for interest, penalties or costs (but not taxes) that are incurred as a result of the gross negligence or willful misconduct of the Partnership or the Managing General Partner.

     (c) Concurrently with the delivery of the audited financial statements for each Fiscal Year pursuant to Section 11.5(a), the Managing General Partner shall prepare and mail, or cause the Partnership’s accountants to prepare and mail, to each Partner and, to the extent necessary, to each former Partner (or such Partner’s designated representatives), a report setting forth in sufficient detail such information relating to the Partnership and its activities as shall enable such Partner or former Partner (or such Partner’s designated representatives) to prepare its respective federal, state, local and foreign income tax returns in accordance with the laws, rules and regulations then prevailing.

     (d) With reasonable promptness, the Managing General Partner will deliver such other information available to the Managing General Partner, including financial statements and computations, as any Partner may from time to time reasonably request in order to comply with regulatory requirements, including reporting requirements, to which such Partner is subject.

     (c) Any action required to be, or which may be, taken at any meeting of the Partners may be taken in writing without a meeting if consents thereto are given by (i) the Managing General Partner, (ii) the Non-Managing General Partner (to the extent

71

such action requires the approval of the Non-Managing General Partner by the terms of this Agreement), and (iii) Partners owning Partnership Interests having an aggregate Percentage Interest not less than the amount that would be necessary to take such action at a meeting; provided that a vote to terminate the Partnership pursuant to Section 12.2 may be held only at a meeting duly called, and not by written consent in lieu thereof.

     (d) A Partner may vote at any meeting either in person or by a proxy which such Partner has duly executed in writing.

     (e) The chairman of any special meeting shall be the President or another Person affiliated with and designated by the Managing General Partner. A Person designated by the Managing General Partner shall keep written minutes of all of the proceedings and votes of any such meeting.

     (f) The Managing General Partner may set in advance a record date for determining the Partners entitled to notice of and to vote at any meeting or entitled to express consent to any action in writing without a meeting. No record date shall be less than ten nor more than sixty days prior to the date of any meeting to which such record date relates nor more than ten days after the date on which the Managing General Partner sets the record date for any action by written consent. If the Managing General Partner does not set a record date, the record date for a meeting of Partners shall be the date of such meeting, and the record date for a written consent of Partners shall be the date of the notice to the Partners by which the Managing General Partner requests such written consent.

     (g) A quorum shall be present at any meeting of Partners with respect to any matter to be voted on at such meeting, if Partners holding voting power at least equal to that required to take action with respect to such matter are present at such meeting. Except as otherwise required by the Act, the Limited Partners may not require the Partnership to take any action, and the consent of the Limited Partners shall not be required for the Partnership to take any action, except to the extent this Agreement requires the taking of an action approved by, or prohibits the taking of any action unless approved by, a specified LP Vote, Partner Vote or Fund Vote. An “LP Vote” is a vote taken among, or consent solicited from, all Limited Partners holding Voting Interests. A “Partner Vote” is a vote taken among, or consent solicited from, all Partners holding Voting Interests. A “Fund Vote” is a vote taken among, or consent solicited from, all Partners holding Voting Interests and all other Voting Fund Investors. A “Majority LP Vote” means the affirmative vote or consent of Limited Partners holding Voting Interests representing more than fifty percent (50%) of the Percentage Interests attributable to Voting Interests held by the Limited Partners on the record date set for an LP Vote. A “Super Majority LP Vote” means the affirmative vote or consent of Limited Partners holding Voting Interests representing sixty-six and two-thirds percent (66-2/3%) or more of the Percentage Interests attributable to Voting Interests held by the Limited Partners on the record date set for an LP Vote. A “75% Majority LP Vote” means the affirmative vote or consent of Limited Partners holding Voting Interests representing seventy-five percent (75%) or more of the Percentage Interests attributable to Voting Interests held by the Limited Partners on the record date set for an LP Vote. A “Majority Partner Vote”

72

means the affirmative vote or consent of Partners holding Voting Interests representing more than fifty percent (50%) of the Percentage Interests attributable to Voting Interests held by the Partners on the record date set for a Partner Vote. A “Super Majority Partner Vote” means the affirmative vote or consent of Partners holding Voting Interests representing sixty-six and two-thirds percent (66-2/3%) or more of the Percentage Interests attributable to Voting Interests held by the Partners on the record date set for a Partner Vote. A “75% Majority Partner Vote” means the affirmative vote or consent of Partners holding Voting Interests representing seventy-five percent (75%) or more of the Percentage Interests attributable to Voting Interests held by the Partners on the record date set for a Partner Vote.

     (h) Each Partner entitled to vote or consent on any matter which under the terms of this Agreement requires an LP Vote or Partner Vote shall have a voting and consent percentage equal to the Percentage Interest attributable to the Voting Interests held by such Partner on the record date set for the meeting or consent at or by which a vote is to be held or a consent is to be taken. Any Feeder Entity may vote or consent any Voting Interest held by it for and/or against any matter presented to the Partners for a vote or consent in such manner and proportions as may be provided for in the constituent documents of such Feeder Entity, as applicable. The Managing General Partner and any Partner that is an Affiliate of the Managing General Partner (including Hines and the Hines Limited Partner) shall be deemed to have voted or granted their consent with respect to any Voting Interests held by them on any matter put to an LP Vote, Fund Vote or Partner Vote in the same manner and proportions as the Voting Interests of the other Partners participating in such vote, were voted or consented.

     (i) The Managing General Partner may, in its discretion, grant to any Partner that holds no Voting Interests and any Fund Investor which is not a Partner the right to have a non-voting observer attend each meeting of the Partners. The Managing General Partner shall provide to any such observer notice of the time and place of any meeting of the Partners, and of any written consent being solicited from the Partner, in the same manner and at the same time as notice is sent to the Partners. The Managing General Partner shall also provide to any such observer copies of all notices, reports, minutes, consents and other documents at the time and in the manner as they are provided to the Partners. Any observer who attends any meetings of the Partners shall execute and comply with an agreement with the Partnership and the Managing General Partner containing such restrictions on the use and disclosure of confidential information and other matters as the Managing General Partner may reasonably request.

     SECTION 11.7 Meetings of Fund Investors. If this Agreement requires any action be taken by or with the consent of Fund Investors by a Fund Vote, such action may be taken only at a meeting of Fund Investors pursuant to a written notice authorized by a Majority LP Vote to all Fund Investors, which notice shall specify the time and place of such meeting (which shall be not less than 30 Business Days after the date of such notice) and the purpose for which such meeting is called. At any meeting of Fund Investors called pursuant to the preceding sentence, each Voting Fund Investor at such meeting, in person or by proxy, that is not an Affiliate of the Managing General Partner shall be entitled to vote at such meeting on the matters specified in the notice by which such meeting was called; provided, that each Partner shall be entitled to vote on

73

such matters only to the extent that such Partner holds Voting Interests. A “Majority Fund Vote” means the affirmative vote of Voting Fund Investors that are not Affiliates of the Managing General Partner holding direct or indirect equity interests in Properties in which the Fund has an interest equal to more than 50% of all equity interests held directly or indirectly by all Voting Fund Investors that are not Affiliates of the Managing General Partner in such Properties. A “Super Majority Fund Vote” means the affirmative vote of Voting Fund Investors that are not Affiliates of the Managing General Partner holding direct or indirect equity interests in Properties in which the Fund has an interest equal to sixty-six and two-thirds percent (66 2/3%) or more of all equity interests held directly or indirectly by all Voting Fund Investors that are not Affiliates of the Managing General Partner in such Properties. A “75% Majority Fund Vote” means the affirmative vote of Voting Fund Investors that are not Affiliates of the Managing General Partner holding direct or indirect equity interests in Properties in which the Fund has an interest equal to seventy-five percent (75%) or more of all equity interests held directly or indirectly by all Voting Fund Investors that are not Affiliates of the Managing General Partner in such Properties. For purposes of this Section 11.7, (i) each Partner shall be deemed to hold an indirect equity interest in each Property in which the Partnership has an indirect interest in an amount equal to the Partnership’s indirect equity interest in such Property multiplied by the Percentage Interest attributable to all Voting Interests held by such Partner, and (ii) equity interests attributable to Class N Partnership Units, or to any other class of equity interest in any Fund Entity or Property specifically designated as a non-voting interest under the Constituent Documents of the issuer of such equity interest, shall be disregarded.

ARTICLE XII

Dissolution, Termination and Winding Up

     SECTION 12.1 Dissolution. The Partnership shall dissolve and its affairs shall be wound up upon the earliest to occur of the following events (each, a “Liquidating Event”):

     (a) an event of withdrawal as defined in Section 17-402 of the Act (such event, an “Event of Withdrawal”);

     (b) there ceasing to be any Limited Partners, as set forth in Section 17-801(4) of the Act (subject to the provisions thereof);

     (c) the entry of a decree of judicial dissolution under Section 17-802 of the Act;

     (d) the election of the Managing General Partner, at any time after the date on which all or substantially all of the assets of the Partnership have been sold or otherwise disposed of; and

     (e) after the Initial Investment Period, the Fund Investors vote to terminate the Partnership in accordance with the provisions of Section 12.2.

provided, however, that upon the occurrence of an Event of Withdrawal with respect to the Managing General Partner, the Partnership may continue its operations if within ninety days after such Event of Withdrawal the Limited Partners elect by Super Majority LP Vote to continue the

74

business of the Partnership and elect a new Managing General Partner, effective as of the date of withdrawal, before or within ninety days after the Event of Withdrawal (in which event a Liquidating Event shall not be deemed to have occurred).

     SECTION 12.2 Termination of Partnership by Majority Fund Vote. After the Initial Investment Period, any Partner may propose that the Partnership be terminated and its affairs wound up in accordance with this Article 12 by delivering a written notice to the Managing General Partner proposing that such action be taken and setting forth the reasons for such proposal. Following receipt of any such notice, the Managing General Partner shall call a special meeting of the Fund Investors in accordance with the provisions of Section 11.7, such meeting to be held on a date not later than the ninetieth day following the Managing General Partner’s receipt of the notice from the Partner proposing such action. A Majority Fund Vote to terminate the Partnership at a special meeting called and held in accordance with the provisions of Section 11.7 and this Section 12.2, shall be deemed a Liquidating Event, following which the Partnership shall be wound up in accordance with Section 12.3.

     SECTION 12.3 Winding up. Upon the occurrence of a Liquidating Event, the Partnership shall proceed to wind up its affairs and liquidate its property and assets as promptly as practicable, but in an orderly manner so as not to involve undue sacrifice. The Managing General Partner, or if there is no Managing General Partner, a liquidator appointed by a Majority LP Vote, shall be the liquidator to wind up the affairs of the Partnership and to manage the Partnership’s assets during the winding up. Following a Liquidating Event resulting from a Majority Fund Vote to terminate the Partnership pursuant to Section 12.2, the Managing General Partner shall complete the winding up of the Partnership no later than the second anniversary of the date of the special meeting of Fund Investors at which such vote occurred.

     SECTION 12.4 Liquidating Distributions. Proceeds from the sales of the Partnership’s assets pursuant to Section 12.3 shall be distributed in one or more installments in the following order of priority:

     (a) Such proceeds shall first be applied to the satisfaction all creditors of the Partnership (including the payment of expenses of the winding-up, liquidation and dissolution of the Partnership), including Partners who are creditors of the Partnership, to the extent otherwise permitted by law, either by the payment thereof or the making of reasonable provision therefor (including the establishment of reserves, in amounts established by the Managing General Partner or, if applicable, the liquidator); and

     (b) The remaining proceeds, if any, plus any remaining assets of the Partnership, shall be applied and distributed to the Partners in accordance with the positive balances of the Partners’ Capital Accounts, as determined after taking into account all adjustments to Capital Accounts for the Partnership taxable year during which the liquidation occurs, by the end of such taxable year or, if later, within ninety days after the date of such liquidation. For purposes of the application of this Section 12.4 and determining Capital Accounts on liquidation, all unrealized gains, losses and accrued income and deductions of the Partnership shall be treated as realized and recognized immediately before the date of distribution. If a Limited Partner shall, upon the advice of counsel, determine that there is a reasonable likelihood that any distribution in kind of an

75

asset would cause such Limited Partner to be in violation of any law, regulation or governmental order, such Limited Partner and the Managing General Partner or the liquidator shall each use its best efforts to make alternative arrangements for the sale or transfer into an escrow account of any such distribution on mutually agreeable terms.

     (c) The parties to this Agreement intend that the allocation provisions contained herein shall produce final Capital Account balances of the Partners that will permit liquidating distributions to be made to the Partners pursuant to this Section 12.4 in accordance with their Percentage Interests. To the extent that the allocation provisions contained in this Agreement fail to produce such final adjusted Capital Account balances, (i) such provisions shall be amended if and to the extent necessary to produce such result, (ii) Profits and Losses of the Partnership (or items of gross income and deduction of the Partnership) shall be allocated by the Partnership among the Partners for current and future years if and to the extent necessary to produce such result, and (iii) the provisions of this sentence shall control notwithstanding any reallocation or adjustment of Profits or Losses (or items thereof) by the Internal Revenue Service or other taxing authority.

ARTICLE XIII

Miscellaneous

     SECTION 13.1 Waiver of Partition. Except as may be otherwise required by law, each Partner hereby irrevocably waives any and all rights that it may have to maintain an action for partition or similar action of any of the Partnership’s property.

     SECTION 13.2 Power of Attorney. Each Limited Partner hereby irrevocably constitutes and appoints the Managing General Partner, with full power of substitution, the true and lawful attorney-in-fact and agent of such Limited Partner, to execute, acknowledge, verify, swear to, deliver, record and file, in its or its assignee’s name, place and stead, all in accordance with the terms of this Agreement, all instruments, documents and certificates which may from time to time be required by the laws of the United States of America, the State of Delaware, any other jurisdiction in which the Partnership conducts or plans to conduct its affairs, or any political subdivision or agency thereof to effectuate, implement and continue the valid existence and affairs of the Partnership, including, without limitation, the power and authority to verify, swear to, acknowledge, deliver, record and file:

     (a) all certificates and other instruments, including any amendments to this Agreement or to the Certificate, which the Managing General Partner deems appropriate to form, qualify or continue the Partnership as a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware and all other jurisdictions in which the Partnership conducts or plans to conduct its affairs,

     (b) any amendments to this Agreement or any other agreement or instrument which the Managing General Partner deems appropriate to (i) effect the addition, substitution or removal of any Limited Partner or Managing General Partner pursuant to this Agreement or (ii) effect any other amendment or modification to this Agreement, but

76

     only if such amendment or modification is duly adopted in accordance with the terms hereof,

     (c) all conveyances and other instruments which the Managing General Partner deems appropriate to reflect the dissolution and termination of the Partnership pursuant to the terms hereof, including the writing required by the Act to cancel the Certificate,

     (e) certificates of assumed name and such other certificates and instruments as may be necessary under the fictitious or assumed name statutes from time to time in effect in the State of Delaware and all other jurisdictions in which the Partnership conducts or plans to conduct its affairs, but only if such names are duly approved in accordance with the terms of this Agreement.

Such attorney-in-fact and agent shall not, however, have the right, power or authority to amend or modify this Agreement when acting in such capacities, except to the extent authorized herein. This power of attorney shall not terminate upon the bankruptcy, dissolution, disability or incompetence of the Managing General Partner. To the fullest extent permitted by law, the power of attorney granted herein shall be deemed to be coupled with an interest, shall be irrevocable, shall survive and not be affected by the dissolution, bankruptcy or legal disability of the Limited Partner and shall extend to its successors and assigns; and may be exercisable by such attorney-in-fact and agent for all Limited Partners (or any of them) by listing all (or any) of such Limited Partners required to execute any such instrument, and executing such instrument acting as attorney-in-fact. Any Person dealing with the Partnership may conclusively presume and rely upon the fact that any instrument referred to above, executed by such attorney-in-fact and agent, is authorized, regular and binding, without further inquiry. If required, each Limited Partner shall execute and deliver to the Managing General Partner within five days after the receipt of a request therefor, such further designations, powers of attorney or other instruments as the Managing General Partner shall reasonably deem necessary for the purposes hereof.

     SECTION 13.3 Amendments.

     (a) Except as required by law, this Agreement (including the Exhibits and Schedules hereto) may be amended or supplemented by written consent of the Managing General Partner, the Non-Managing General Partner and the Limited Partners by a Majority LP Vote; provided that no such amendment shall (i) increase any Partner’s Capital Commitment, reduce its share of the Partnership’s distributions, income and gains or materially and adversely affect the rights granted to or liabilities (including tax liabilities) of such Partner hereunder, without the written consent of each Partner so affected, (ii) change the LP Vote, Partner Vote or Fund Vote required hereunder (the “Required Vote”) for the taking of an action unless such amendment is approved by the Required Vote for the subject of such proposed amendment, (iii) amend this Section 13.3 or the Investment Guidelines without the consent of each Partner, (iv) amend the definition of Percentage Interest, Section 3.7(b), subsection (a), (d), (e) or (h) of Section

77

5.3 or Section 5.10 in a way that would materially and adversely affect SLR without the consent of at least one SLR Designee or amend the first or second sentence of Section 2.2 or this clause (iv) of this Section 13.3(a) without the consent of SLR, or (v) amend Section 3.5 without the consent of Partners holding at least sixty-six and two-thirds percent (66 2/3%) of the outstanding Class N Partnership Units. Notwithstanding the foregoing, but subject to the next sentence, this Agreement may be amended by the Managing General Partner without the consent of any other Partner to (a) cure any ambiguity or correct or supplement any provision hereof which is incomplete or inconsistent with any other provision hereof or correct any printing, stenographic or clerical error or omissions, provided that such amendment does not materially adversely affect the interests of the Partners, (b) amend Sections 8.4 to 8.8 as provided therein, (c) in connection with a Subsequent Closing, amend any provision of this Agreement, provided that such amendment does not materially adversely affect the rights or obligations of the existing Partners, and (d) make any amendment that is not objected to in writing by any Partner within twenty Business Days after notice of such amendment is given to all Partners. Notwithstanding the preceding sentence, the Managing General Partner will obtain the approval of the Non-Managing General Partner for any amendments, revisions or modifications to Section 5.2 or any other provisions of this Agreement with respect to investment policies or procedures.

     (b) The Managing General Partner shall have the right to amend this Agreement without the approval of any other Partner to the extent the Managing General Partner reasonably determines, based upon written advice of tax counsel to the Partnership, that the amendment is necessary to provide assurance that the Partnership will not be treated as a “publicly traded partnership,” because it is entitled to “safe harbor” treatment under Section 7704 of the Code and the regulations promulgated thereunder; provided that (i) such amendment shall not change the relative economic interests of the Partners, reduce any Partner’s share of distributions, or increase any Partner’s Capital Commitment or its liability hereunder, (ii) the Managing General Partner provides a copy of such written advice and amendment to the Limited Partners at least twenty Business Days prior to the effective date of any such amendment and the Partners shall not have made a reasonable objection to such amendment prior to the effective date of such amendment by a Majority Partner Vote.

     SECTION 13.4 Confidentiality. Each Limited Partner agrees to keep confidential, and not to make use of (other than for purposes reasonably related to its interest in the Partnership or for purposes of filing such Limited Partner’s tax returns or for other routine matters required by law) or disclose to any Person, any information or matter relating to the Partnership and its affairs and any information or matter related to any Investment (other than disclosure to such Limited Partner’s employees, agents, advisors, or representatives responsible for matters relating to the Partnership), including any information contained in any Capital Call or any report distributed pursuant to Section 11.5; provided that a Limited Partner may disclose any such information to the extent that (i) such information is or becomes generally available to the public through no act or omission of such Limited Partner, (ii) such information otherwise is or becomes known to such Limited Partner other than by disclosure by the Partnership or the Managing General Partner, provided that the source of such information is not bound by a confidentiality agreement or other contractual, legal or fiduciary obligation of confidentiality, or

78

(iii) such Limited Partner is required by law to disclose such information. Each Limited Partner shall cause its employees, agents, advisors, or representatives to comply with the provisions of this Section 13.4, and shall be liable to the Partnership and the Managing General Partner for any breach of this Section 13.4 by any such Person.

     SECTION 13.5 Entire Agreement. This Agreement and the other agreements referred to herein constitute the entire agreement among the Partners with respect to the subject matter hereof and supersede any prior agreement or understanding among or between them with respect to such subject matter; provided that the Partnership or the Managing General Partner, without any further act, approval or vote of any Partner, may (subject to Section 13.3) enter into side letters or other writings with individual Partners which have the effect of establishing rights under, or altering or supplementing, the terms of, this Agreement as to such Partner. Any rights established, or any terms of this Agreement altered or supplemented, in a side letter with a Partner shall govern with respect to such Partner notwithstanding any other provision of this Agreement. The representations and warranties of the Partners in, and the other provisions of, the Subscription Agreements shall survive the execution and delivery of this Agreement.

     SECTION 13.6 Severability. Each provision of this Agreement shall be considered severable and if for any reason any provision which is not essential to the effectuation of the basic purposes of this Agreement is determined by a court of competent jurisdiction to be invalid or unenforceable and contrary to the Act or existing or future applicable law, such invalidity shall not impair the operation of or affect those provisions of this Agreement which are valid. In that case, this Agreement shall be construed so as to limit any term or provision so as to make it enforceable or valid within the requirements of any applicable law, and in the event such term or provision cannot be so limited, this Agreement shall be construed to omit such invalid or unenforceable provisions.

     SECTION 13.7 Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given if (i) mailed, registered mail, first-class postage paid, (ii) sent by overnight mail or courier, or (iii) delivered by hand, if to any Partner, at such Partner’s address, or to such Partner’s facsimile number, set forth on Schedule 2.1, if applicable, or as set forth in such Partner’s Subscription Agreement, and if to the Partnership, to the Managing General Partner at the Managing General Partner’s address, or to the Managing General Partner’s facsimile number, set forth on Schedule 2.1, or to such other person or address as any Partner shall have last designated by notice to the Partnership, and in the case of a change in address by the Managing General Partner, by notice to the Limited Partners. Any notice shall be deemed to have been duly given if personally delivered or sent by the mails or courier or by electronic mail or facsimile confirmed by letter and will be deemed received, unless earlier received, (i) if sent by certified or registered mail, return receipt requested, when actually received, (ii) if sent by overnight mail or courier, when actually received, and (iii) if delivered by hand, on the date of receipt.

     SECTION 13.8 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware. In particular, the Partnership is formed pursuant to the Act, and the rights and liabilities of the Partners shall be as provided therein, except as herein otherwise expressly provided.

79

     SECTION 13.9 Successors and Assigns. Except with respect to the rights of Indemnified Parties hereunder, none of the provisions of this Agreement shall be for the benefit of or enforceable by the creditors (other than a lender pursuant to the terms of any agreement governing or securing Indebtedness to which such lender and the Partnership are parties) of the Partnership and this Agreement shall be binding upon and inure to the benefit of the Partners and their legal representatives, heirs, successors and permitted assigns.

     SECTION 13.10 Headings. The Article and Section headings in this Agreement are for convenience of reference only, and shall not be deemed to alter or affect the meaning or interpretation of any provisions hereof.

     SECTION 13.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which, when taken together, shall constitute one and the same instrument.

     SECTION 13.12 Third Party Beneficiary. If SLR ceases to be a Limited Partner, then, subject to Section 5.3(h), SLR shall be a third party beneficiary under this Agreement as to all rights granted to SLR hereunder. The rights granted to SLR in this Agreement were a material inducement to Sumitomo in its agreement to convey the Initial Asset Group to the Fund, SLR is relying upon such rights, and SLR shall have the right, without limitation of any other rights it may have as a third party beneficiary of this Agreement, to seek enforcement of such rights in its own name in accordance with the terms of this Agreement and the Act.

Hines Investment Allocation Procedure

If Hines becomes aware of investment opportunities which are permitted investments for the Partnership and are not covered by clauses (a) through (c) of Section 4.4, and which the fund manager of NOP wishes to pursue on behalf of NOP, Hines shall cause such investment opportunities to be allocated on a rotating basis between the Partnership and NOP, in each case based on the chronological order in which such opportunities arose (as determined in good faith by the Hines Investment Allocation Committee).

          The attached schedule illustrates, for the first two Fiscal Quarters after the Initial Investment Period: (1) how the Percentage Interest of the holder of a Participation Interest is calculated in each quarter (assuming that Hines is the only Partner which acquires a Participation Interest during this period), and (2) how the Units of the Unaffiliated Limited Partners are automatically cancelled as the result of the grant of the Participation Interest in each quarter. These calculations are based upon hypothetical investments by various classes of Partners, assumed capital contributions, hypothetical equity investments in new properties, and a Current Unit Value of $1,000.
