CAPITAL

SECTION 2.1. Initial Capital Contributions; Distribution to the ▇▇▇▇ Members.

(a) Upon the execution of this Agreement the Company shall purchase certain of the Properties from Development Inc. and Development LP as designated in Exhibits ▇-▇, ▇-▇ ▇▇▇ ▇-▇ for the purchase prices set forth in ▇▇▇▇▇▇▇▇ ▇-▇,▇-▇ and A-3.

(b) Upon the execution of this Agreement, the ▇▇▇▇ Members shall make their Initial Capital Contributions to the Company by conveying the Properties set forth in Exhibits ▇-▇, ▇-▇ and A-3 to the Company at the values set forth next to each of the Properties in Exhibits ▇-▇, ▇-▇ and A-3 and the ▇▇▇▇ Members shall be deemed to have made Initial Capital Contributions in the amounts set forth next to their names in Exhibit B.

(c) Upon execution of this Agreement, NYSTRS shall make its Initial Capital Contribution to the Company of cash in the amount set forth next to its name on Exhibit B hereto. The Members hereby agree that a portion of the Initial Capital Contribution of NYSTRS shall be applied by the Company toward the purchase of the Properties described in Section 2.1(a) and also as a distribution to the ▇▇▇▇ Members. Such distribution shall also be utilized to pay and discharge certain liabilities which were incurred in connection with the financing of the Properties as described more particularly in Exhibit C annexed hereto.

(d) Immediately subsequent to the Initial Capital Contributions of the Members set forth above, the Company shall pay the purchase prices for the Properties described in, and in the amounts set forth in, Section 2.1(a) and shall make distributions to the ▇▇▇▇ Members equal to the amounts set forth in Exhibit B.

SECTION 2.2. Operating Capital; Additional Capital Contributions. In the event at any time or from time to time additional funds are necessary to (i) operate the Developed Properties, and Gross Receipts together with the proceeds of any reserve account established by the Company may be insufficient to pay all Operating Expenses when due, or if sufficient funds are otherwise unavailable to fund amounts required for the Developed Properties (ii) fund amounts required to pay non-discretionary items or to develop Properties pursuant to the requirements of Section 6.5 or otherwise in accordance with approved Business Plans or (iii) fund any amounts required to remedy an emergency situation (i.e., payment of real property taxes or insurance premiums or to complete emergency repairs) in connection with any of the Existing Properties (in each case, a “Shortfall”), then the Managing Member shall notify each Member of such Shortfall (a “Shortfall Notice”) identifying the amount of such Shortfall (the “Shortfall Amount”). Within ten (10) Business Days after receipt of the Shortfall Notice, each Member shall make a cash Capital Contribution to the Company (each, an “Additional Capital Contribution”) in an amount equal to the Shortfall Amount specified in the Shortfall Notice

-21-

multiplied by such Member’s Percentage Interest in the Company such that such amount of the Shortfall specified by the Managing Member shall not exist subsequent to the Due Date. Additional Capital Contributions shall be credited to the Capital Account of the Members making such Additional Capital Contributions. The Managing Member shall consult with the other Members within a reasonable period of time prior to delivering any Shortfall Notice and any Major Decision requiring the expenditure of funds shall be subject to the requirements of Section 6.3. The Managing Member shall give evidence to NYSTRS of any Additional Capital Contributions made by the ▇▇▇▇ Members.

SECTION 2.3. Default Loans. (a) If any Member shall fail to advance any Additional Capital Contribution pursuant to Section 2.2 hereof on or before the Due Date thereof then the Managing Member shall give immediate notice to any Member failing to advance the Additional Capital Contribution (a “Defaulting Member”). Should any Defaulting Member fail to advance the Additional Capital Contribution within ten (10) days after such notice, then each non-defaulting Member (a “Non-Defaulting Member”) that does not have an outstanding Default Loan made to it hereunder (a “Lending Eligible Member”) shall have the right, but not the obligation, to make a loan (a “Default Loan”) to such Defaulting Member in an amount equal to the Defaulting Member’s Percentage Interest of such Additional Capital Contribution within thirty (30) days after the Due Date. If a Default Loan(s) shall be made in accordance with this Section 2.3, the Company shall also notify the Defaulting Member of the amount and date of the Default Loan(s). Each Default Loan shall be deemed to be made to the Defaulting Member, with the proceeds of each Default Loan by the Lending Eligible Member making same being delivered to the Company in immediately available funds on such Defaulting Member’s behalf. A Default Loan shall be deemed to have been advanced on the Due Date. Default Loans shall earn interest on the outstanding principal amount thereof at a rate equal to the lesser of (i) the Default Loan Rate or (ii) the Maximum Rate, from the Due Date until the same is repaid in full.

(b) Default Loans shall be non-recourse, secured as provided in paragraph (c) of this Section 2.3 and shall have a term of ninety (90) days and be repayable by and collectible from the Defaulting Member only as set forth in this Section 2.3(b). A Member making a Default Loan (a “Lending Member”) may, in the exercise of such Member’s sole and absolute discretion, extend (for a period(s) to be determined by such Member) the term of a Default Loan. If a Member makes a Default Loan, the Defaulting Member shall not receive any distributions of Net Cash Flow or Net Proceeds of a Capital Transaction or any proceeds from the transfer of all or any part of its interest in the Company while the Default Loan remains unpaid. Instead, the Defaulting Member’s share of Net Cash Flow and Net Proceeds of a Capital Transaction or such other proceeds shall (until all Default Loans and interest thereon shall have been repaid in full) first be paid to the Lending Member. Such payments shall be applied first to the payment of interest on such Default Loans and then to the repayment of the principal amounts thereof, but shall be considered, for all other purposes of this Agreement, to have been distributed to the Defaulting Member. Distributions of Net Cash Flow to such Defaulting Member shall be reinstated prospectively upon the full repayment of a Default Loan and interest thereon to the Lending Member (if a Default Loan has been made). In addition, at any time during the term of

-22-

such Default Loan, the Defaulting Member shall have the right to repay, in full, the Default Loan (including interest).

(c) If a Member makes a Default Loan, the Defaulting Member shall be deemed to have pledged to the Lending Member, and granted to such Lending Member a continuing first priority security interest in, all of the Company Interest of the Defaulting Member and all distributions of Net Cash Flow or Net Proceeds of a Capital Transaction due to a Defaulting Member (it being understood that if any one of the ▇▇▇▇ Members is a Defaulting Member that such first priority security interest shall be secured by all of the Company Interests of the ▇▇▇▇ Members and such distributions payable to all of the ▇▇▇▇ Members) to secure the payment of the principal of, and interest on, such Default Loan in accordance with the provisions hereof, and for such purpose this Agreement shall constitute a security agreement. The Defaulting Member shall promptly execute, acknowledge and deliver such financing statements, continuation statements or other documents and take such other actions as the Lending Member shall request in order to perfect or continue the perfection of such security interest; and, if the Defaulting Member shall fail to do so within seven (7) days after demand therefor, the Lending Member is hereby appointed the attorney-in-fact of, and is hereby authorized on behalf of, the Defaulting Member, to execute, acknowledge and deliver all such documents and take all such other actions as may be required to perfect such security interest. Such appointment and authorization are coupled with an interest and shall be irrevocable. Any Lending Member holding a security interest in such Company Interest of a Defaulting Member or in distributions of Net Cash Flow or Net Proceeds of a Capital Transaction due to a Defaulting Member as a result of the making of a Default Loan to such Defaulting Member shall, prior to exercising any right or remedy (whether at law, in equity or pursuant to the terms hereof) available to such Lending Member in connection with such security interest, provide to the Defaulting Member written notice, in reasonable detail, of the right or remedy to be exercised and the intended timing of such exercise.

(d) If the Defaulting Member shall fail to make an Additional Capital Contribution and such failure constitutes a “Member Material Default”, then the Defaulting Member and its representatives on the Management Committee shall have no further voting right or right to participate in the management of the Company until the default due to the failure to make the Additional Capital Contribution is cured, it being understood that if any of the ▇▇▇▇ Members is a Defaulting Member, then the ▇▇▇▇ Committee Member shall have no further voting rights until such default is cured. “Member Material Default” shall mean a default by the Defaulting Member (for this purpose and pursuant to Section 3.4 the ▇▇▇▇ Members shall be deemed to act as a single entity) after expiration of the ten (10) day notice provision set forth in Section 2.3(a) to contribute Additional Capital Contributions in the aggregate during the existence of the Company an amount greater than One Million Dollars ($1,000,000). During the continuance of a Member Material Default, the Company shall be managed without regard to the voting rights of any Member in Member Material Default, and decisions otherwise subject to the consent and/or approval and/or participation of such Member in Member Material Default (or its representative on the Management Committee) shall be made without the necessity of obtaining

-23-

the consent and/or approval and/or participation of such Member in Member Material Default (or its representative on the Management Committee).

SECTION 2.4. No Third Party Beneficiaries. The right of the Managing Member to require an Additional Capital Contribution or the right of a Member to make a Default Loan pursuant to Section 2.3 shall not confer upon any creditor or other third party having dealings with the Company any right, claim or other benefit, including the right to require any such Additional Capital Contribution or Default Loan.

No Member shall be required to pay to the Company or to any other Member any deficit in its Capital Account upon dissolution of the Company or otherwise, and no Member shall be entitled to withdraw any part of its Capital Contributions or Capital Account, to receive interest on its Capital Contributions or Capital Account or to receive any distributions from the Company, except as expressly provided for in this Agreement or under the Delaware Act as then in effect.

SECTION 3.4. ▇▇▇▇ Members; NYSTRS Members. Unless explicitly provided herein to the contrary, the term “Member” shall refer to NYSTRS and any Affiliates thereof should a Transfer occur pursuant to Section 8.3(a), and their successors and assigns (the “NYSTRS Affiliated Members”), on the one hand, and the ▇▇▇▇ Members and any Affiliates thereof should a Transfer occur pursuant to Section 8.4(a), and their successors and assigns (the “▇▇▇▇ Affiliated Members”), on the other hand. Any reference in this Agreement to the “▇▇▇▇ Members,” or to the ▇▇▇▇ Members collectively as a Member, shall be deemed to refer to the ▇▇▇▇ Affiliated Members in the aggregate as set forth in this Section 3.4. Unless explicitly provided herein to the contrary, the ▇▇▇▇ Affiliated Members shall be treated for all purposes of this Agreement as if the ▇▇▇▇ Affiliated Members’ Company Interests were held as a single, aggregate Company Interest by a single entity. The aggregate obligations of the ▇▇▇▇ Affiliated Members under this Agreement may be satisfied or performed by any one or more of the ▇▇▇▇ Affiliated Members.

Notwithstanding anything herein to the contrary, the NYSTRS Affiliated Members shall similarly be considered collectively as a single Member for all intents and purposes of this Agreement, under the same provisions set forth above applicable to the ▇▇▇▇ Affiliated Members, provided that the NYSTRS Affiliated Members shall act through or at the direction of NYSTRS hereunder.

(c) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations, or distributions described in paragraphs (4), (5) and (6) of Treasury Regulations Section 1.704-1(b)(2)(ii)(d), items of Company income and gain shall be specially allocated to such Members in an amount and manner sufficient to eliminate, to the extent required by such Regulations, the Adjusted Capital Account deficit of such Members as quickly as possible, provided that an allocation pursuant to this Section 5.3(c) shall be made only if and to the extent that such Member would have an Adjusted Capital Account deficit after all other allocations provided for in this Article 5 have been tentatively made as if this Section 5.2(c) were not in the Agreement.

(f) Limitation on Allocation of Losses. In no event shall Losses be allocated to a Member to the extent such allocation would result in such Member having an Adjusted Capital Account deficit at the end of any Fiscal Year.

The Managing Member shall make such election upon the receipt of notice from a Members having a majority of the Percentage Interests.

(h) Special Allocations. Notwithstanding any other provision of this Agreement, allocations under this Section 5.2 shall be made only to the extent that, and shall be

-28-

adjusted to the extent necessary to ensure that, the Company’s allocations satisfy the requirements of Code Section 514(c)(9)(E), the Treasury Regulations promulgated thereunder and any administrative guidelines or pronouncements thereunder, including so that all allocations have “substantial economic effect” for purposes of Code Section 514(c)(9)(E)(i)(II). Further, to the extent an allocation made pursuant to this Section 5.2 causes the ratio of Members’ Capital Account balance to differ from the ratio of their Percentage Interests, an effecting “chargeback” allocation shall be made to restore the Members’ Capital Account balances to be in proportion to their Percentage Interests at the earliest possible time permitted by the Treasury Regulations promulgated under Code Sections 704 and 514(c)(9)(E).

The allocations contained in Sections 5.2(a) through 5.3(g) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Code and Treasury Regulations. The Members intend that, to the extent possible, all Regulatory Allocations shall be offset either by other Regulatory Allocations or with special allocations of other items of Company income, gain, loss or deduction pursuant to this Section 5.2(i). Therefore, notwithstanding any other provisions of this Article 5 (other than the Regulatory Allocations and Section 5.2(h)), the Members shall make such offsetting special allocations of Company income, gain, loss or deduction in whatever manner they reasonably determine to be appropriate so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement.

(a) For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such other items shall be determined on a daily, monthly, or other basis, as reasonably determined by the Members using any permissible method under Code Section 706 and the Treasury Regulations thereunder.

(b) Except as otherwise provided in this Agreement, all items of Company income, gain, loss, deduction, and any other allocations not otherwise provided for shall be divided among the Members for tax purposes in the same proportions as they share Profits or Losses, as the case may be, for the Fiscal Year.

(c) The Members are aware of the income tax consequences of the allocations made by this Article 5 and hereby agree to be bound by the provisions of this Article 5 in reporting their shares of Company income and loss for income tax purposes.

(a) In accordance with Code Section 704(c) and the Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its initial Gross Asset Value.

(b) The parties shall have the following rights upon termination of any one or more of the Property Management Agreements or the Development Agreements:

(i) Notwithstanding any other term of this Agreement, should an Unpermitted Transfer on the part of the ▇▇▇▇ Members occur, and should NYSTRS in its sole and absolute discretion elect to cause the Company to terminate any one or more of the Property Management Agreements or Development Agreements, and NYSTRS is hereby authorized to do so, or if any or all of the Property Management Agreements are terminated pursuant to Section 6.4(a), then during the sixty (60) day period after such termination NYSTRS, at its option, may exercise sale rights for all the Properties pursuant to Section 8.6, or buy-sell rights for all the Properties pursuant to Section 8.7 or all of the Company Interests of the ▇▇▇▇ Members pursuant to Section 8.8, at any time prior to or subsequent to the Lockout Date during such sixty (60) day period. Should NYSTRS not exercise such rights in a timely fashion, then the ▇▇▇▇ Members, acting as a group, may exercise during the subsequent sixty (60) day period after termination of the initial sixty (60) day period, sale rights for all the Properties pursuant to Section 8.6 or buy-sell rights for all the Properties pursuant to Section 8.7 or all of the Company Interests of NYSTRS pursuant to Section 8.8. Should neither NYSTRS exercise such rights during the initial sixty (60) day period, nor the ▇▇▇▇ Members exercise such rights during the subsequent sixty (60) day period, then neither NYSTRS or the ▇▇▇▇ Members shall have the right to exercise any sale rights pursuant to Section 8.6 or buy-sell rights pursuant to Section 8.7 or Section 8.8 in connection with the particular Unpermitted Transfer in question, other than as otherwise permitted by clause (ii) below or Article VIII. Further, if any of the Property Management Agreements or Development Agreements are electively terminated pursuant to the terms thereof, or due to an Owner’s default not caused by the ▇▇▇▇ Members, then the ▇▇▇▇ Members, acting as a group, may exercise the foregoing rights during the subsequent sixty (60) day period after such termination.

(ii) Should an Unpermitted Transfer by a ▇▇▇▇ Member occur, and should NYSTRS elect not to cause the Company to terminate any one or more of the Property Management Agreements or Development Agreements, then during the ensuing year after the Unpermitted Transfer NYSTRS, at its option, may exercise sale rights for all of the Properties pursuant to Section 8.6 or buy-sell rights for all of the Properties pursuant to Section 8.7 or all of the Company Interests of the ▇▇▇▇ Members pursuant to Section 8.8, at any time prior to or subsequent to the Lockout Period during such one (1) year period. Should NYSTRS not exercise such rights during such one (1) year period then NYSTRS shall not have the right to exercise any sale rights pursuant to Section 8.6 or buy-sell rights pursuant to Section 8.7 or Section 8.8 in connection with the particular Unpermitted Transfer in question, other than as otherwise permitted by Article VIII.

SECTION 6.5. Development Decisions. The Managing Member shall monitor the completion of all work at the Properties Under Development in conformance with a development

-35-

budget (“Development Budget”), in accordance with a schedule (“Development Schedule”) and pursuant to plans and specifications (“Development Plans and Specifications”), which have been approved by NYSTRS and which are attached hereto as part of the Business Plan attached as Exhibit E. Any Undeveloped Properties that the Company may decide to develop from time to time shall be considered “New Projects” and shall henceforth be considered Properties Under Development for all intents and purposes of this Agreement. Likewise, Properties Under Development which are completed shall henceforth be considered Developed Properties for all intents and purposes of this Agreement. The Company from time to time, with the approval of the Management Committee, may decide to acquire new properties, and upon acquisition such new properties shall be considered Properties for all intents and purposes of this Agreement. Depending upon the circumstances, such newly acquired properties may be Developed Properties, Properties Under Development or Undeveloped Properties. The Management Committee shall approve all future Development Budgets, Development Schedules and Development Plans and Specifications relating to the Properties Under Development or New Projects. All Properties Under Development shall be constructed in accordance with existing construction contracts which have been approved by NYSTRS. All new construction contracts for Properties under Development or New Projects must be guaranteed maximum price contracts, stipulated sum contracts or otherwise approved by the Management Committee. All requisitions for payment or periodic reports required to be delivered by the developer to the Company or its representative under the Development Agreements shall, at the option of NYSTRS, be delivered also to NYSTRS and/or its construction consultant, it being understood that such construction consultant shall have no independent approval rights but shall review the requisitions for the benefit of NYSTRS. Additional costs attributable to change orders, cost overruns or other obligations of the Company shall be covered by borrowings of the Company or through Additional Capital Contributions, as proposed by the Managing Member and, if the applicable modification to any Development Budgets, Development Schedules and Development Plans and Specifications, taken in the aggregate as to all modifications, would constitute a “Material” modification, approved by the Management Committee. The Managing Member shall use reasonable efforts to avoid multiple requests for Additional Capital Contributions in any one month. The Company shall commence development of the Undeveloped Properties and New Projects pursuant to Development Budgets, Development Schedules and Development Plans and Specifications proposed by the Managing Member and approved by the Management Committee. The Management Committee must approve any Material modifications to the Development Budgets, the Development Schedules or the Development Plans and Specifications for the Undeveloped Properties, the Properties Under Development and New Projects. The Managing Member shall monitor all development of the Properties Under Development, the Undeveloped Properties and New Projects pursuant to the Development Agreements and shall keep the Management Committee informed of all development activities with regard thereto. With regard to the Undeveloped Properties, the Managing Member annually at the commencement of each Fiscal Year shall propose annual development plans for development of the Undeveloped Properties proposed to be developed in the ensuing Fiscal Year in concept form for the approval of the Management Committee, setting forth, amongst other factors, the Undeveloped Properties to be developed, the proposed yield parameters and expected capital and financing requirements,

-36-

together with material information concerning the remaining Undeveloped Properties in each Subportfolio that are not covered by the conceptual development plans. After approval of the annual conceptual development plans by the Management Committee, the Managing Member shall develop detailed Development Budgets, Development Schedules and Development Plans and Specifications for the approval of the Management Committee. The Development Budgets, Development Plans and Specifications and Development Plans and Specifications approved by the Management Committee shall become part of the annual Business Plan. All proposed borrowings or required Additional Capital Contributions requested in the year in question for future development shall be set forth in the components of such approved Business Plan. The Managing Member shall proceed to develop the Properties Under Development, the Undeveloped Properties and the New Projects in conformance with the approved Business Plan. Notwithstanding the above, the Managing Member may make modifications to the Development Budgets, Development Schedules and Development Plans and Specifications for a single Property Under Development or New Project which are not “Material” without the approval of the Management Committee. For purposes of this Section 6.5:

(a) A “Material” change to a Development Budget shall mean an increased cost of more than the greater of (i) ten percent (10%) or (ii) $20,000, in any single line item; provided that not more than fifty percent (50%) of the contingency line item is committed and the total overall cost for the Property Under Development or New Project is not increased; and provided, further, that savings attributable to any line item covering any “hard” costs shall not be transferred to any line item covering any “soft” costs, or vice versa, without the approval of the Management Committee.

(b) A “Material” change to a Development Schedule shall mean a delay in construction of at least three (3) months (exclusive of unavoidable delay) provided that the total cost for the Property Under Development or New Project is not increased.

(c) A “Material” change in the Development Plans and Specifications means any proposed change orders that would cause a Material change in the Development Budget as set forth in Section 6.5(a).

SECTION 6.6. Business Plan. The current business plan (“Business Plan”) is attached hereto as Exhibit E. Future Business Plans for subsequent Fiscal Years shall consist of the following components:

(a) The Budget for the individual Properties, each Subportfolio and all of the Properties approved by the Management Committee pursuant to Section 7.6.

(a) The Members, in connection with their respective duties and responsibilities hereunder, shall at all times act in good faith and, except as expressly set forth herein, any decision or exercise of right of approval, consent, disapproval or deferral of approval by a Member is to be made by such Member pursuant to the terms of this Agreement in good faith, in the exercise of commercial reasonableness for an owner and operator of suburban office buildings commensurate in quality with the standard of quality of the Existing Properties, it being recognized that each Member may act in its own economic self interest and in accordance with such tax and business objectives as it deems appropriate or desirable for such Member. Except as otherwise agreed to in writing by the Members, no Member or any partner, officer, shareholder or employee of any Member shall receive any salary or other remuneration for its services rendered pursuant to this Agreement.

(b) Each Member recognizes that the other Members have or may have other business interests, activities and investments, some of which may be in conflict or competition with the business of the Company and that such other Member is entitled to carry on such other business interests, activities and investments. No Member shall be obligated to devote all or any particular part of its time and effort to the Company and its affairs.

SECTION 6.8. Company’s Counsel. To the extent that the Management Committee deems necessary, the Company shall retain legal counsel to be the Company’s initial legal counsel (the “Company’s Counsel”). The fees and expenses of the Company’s Counsel shall be a Company expense. The Managing Member shall further have the power to appoint or approve the retention, at the Company’s expense, of additional counsel to represent the Company in the ordinary course of business. Nothing herein shall restrict any such counsel from acting as counsel to any Member or any Affiliate of such Member, provided that such representation shall not be continued in any adversarial context or would otherwise conflict with standards of professional conduct. In the event the Management Committee shall desire to terminate the employment of the Company Counsel and to substitute other counsel therefore, such substitute counsel shall be subject to the approval of the Management Committee.

SECTION 6.9. Exculpation. The Managing Member shall act as fiduciary hereunder and in good faith, but neither the Managing Member nor any other entity replacing CarrAmerica and acting as Managing Member hereunder shall be liable to the Company or to any Member for any act performed or omitted to be performed by it on behalf of the Company, provided such act or omission was taken in good faith, was reasonably believed by the Managing Member to be in the interests of the Company and within the scope of authority granted or reserved to the Managing Member under this Agreement, and did not constitute fraud or willful misconduct. Notwithstanding any other term of this Agreement:

(a) It will not constitute a breach of fiduciary or other duty for the Managing Member, or any Affiliate of the Managing Member, to engage in activities of the type conducted by the Company, even if in direct competition with the Company, including without limitation, the purchase, sale and leasing of commercial office properties or the purchase, sale, leasing, management or development of any real property.

-38-

The Managing Member shall not be responsible for any misconduct or negligence on the part of any such attorney, accountant or other advisor.

(d) It will not constitute a breach of fiduciary or other duty for the Managing Member, or an Affiliate of the Managing Member, to contract or enter into any agreement or arrangement with the Company with respect to any aspect of the operations of the Company if approved by the Management Committee or NYSTRS after full disclosure to all of the Members.

SECTION 6.10. Intentionally Deleted.

The Managing Member shall submit to NYSTRS written notice containing all material details of any proposed transaction that the Managing Member reasonably believes, based upon directions

-39-

and/or guidelines provided by NYSTRS or other Members, could result in the realization of UBTI by any Member, or any of a Member’s direct or indirect members or participants, or the realization of income that would be UBTI if a Member, or any of a Member’s direct or indirect members or participants, were subject to the provisions of Sections 511 through 514 of the Code, and NYSTRS shall consult with the Managing Member regarding the proposed transaction.

(b) If neither NYSTRS nor the ▇▇▇▇ Members exercise their rights under Section 6.14(a) then neither NYSTRS nor the ▇▇▇▇ Members shall have any further rights to exercise such sale or buy-sell rights in connection with the removal of the Managing Member, except as such rights may otherwise be available to NYSTRS or the ▇▇▇▇ Members pursuant to Article VIII.

SECTION 6.15. Dispute Resolution. The Members shall cause their representatives on the Management Committee to act reasonably and in good faith to resolve any disputes related to Major Decisions.

The Managing Member shall nevertheless be authorized to pay increases in real estate taxes and other similar non-discretionary items. After the Lockout Date, if, despite

All such appraisals shall be certified and delivered to both NYSTRS and the Company.

Should an Unpermitted Transfer by NYSTRS occur, either before or after the Lockout Date, then in such circumstance such Unpermitted Transfer shall not constitute a

SECTION 8.3. Transfers by NYSTRS.

(a) Notwithstanding any other term of this Agreement, at any time NYSTRS may from time to time, in its sole discretion, Transfer all or any portion of its Company Interest to any Affiliate of NYSTRS. From and after the Lockout Date, NYSTRS may Transfer all of its Company Interest, subject to the provisions of Section 8.3(b), to any person, firm, corporation or entity, provided any such assignee assumes the obligations to be performed by NYSTRS hereunder, and provided further that the ▇▇▇▇ Members approve any such Transfer, such approval not to be unreasonably withheld or delayed. In connection with such approval, the ▇▇▇▇ Members shall be acting reasonably if the ▇▇▇▇ Members refuse to grant approval because the proposed transferee or its Affiliate is (i) a competitor of the ▇▇▇▇ Members in connection with the ownership and/or development of office real estate in the markets where the ▇▇▇▇ Members or their Affiliates own properties (but not as a passive, non-controlling investor), (ii) a real estate company (not including a real estate subsidiary of an institutional investor, such as an insurance company) whose shares are publicly traded, or (iii) an entity or an Affiliate thereof with which the ▇▇▇▇ Members have engaged in litigation or have engaged in a material dispute.

(b) Should NYSTRS desire to Transfer all of its Company Interest as permitted by Section 8.3(a), then NYSTRS shall first deliver to the ▇▇▇▇ Members an offer (the “NYSTRS Offer”) to sell the NYSTRS’s Company Interest together with the material terms (the “NYSTRS Sale Material Terms”), which shall be the same terms, including, without limitation, sales price, as offered to the proposed transferee by NYSTRS in connection with the Transfer proposed under Section 8.3(a). The ▇▇▇▇ Members shall have sixty (60) days from the receipt of the NYSTRS Offer, time being of the essence, to deliver a notice (the “▇▇▇▇ Acceptance”) to NYSTRS, in writing, that the ▇▇▇▇ Members agree to purchase the NYSTRS’s Company Interest on the NYSTRS Sale Material Terms in accordance with the provisions of this Section. In the event the ▇▇▇▇ Members deliver the ▇▇▇▇ Acceptance as aforesaid, (i) the purchase and sale shall occur on the NYSTRS Sale Material Terms (provided, however, the closing shall occur no later than ninety (90) days from the date of the NYSTRS Offer), (ii) NYSTRS shall deliver to the ▇▇▇▇ Members at the closing of such purchase and sale, a duly executed, sealed and acknowledged

-48-

instrument assigning to the ▇▇▇▇ Members, the NYSTRS’s Company Interest, which assignment shall be accompanied by such other documents and instruments, including, without limitation, corporate resolutions, as may be requested by the ▇▇▇▇ Members and the Company in the exercise of their reasonable judgment (iii) on the effective date of such assignment, the Company shall deliver a release to NYSTRS releasing NYSTRS from all liabilities and obligations of the Company arising from and after the date of such assignment. Such assignment shall be free and clear of all liens and encumbrances, and NYSTRS shall deliver to the ▇▇▇▇ Members a written representation and warranty to such effect at the closing, which representation and warranty shall survive the closing. All costs and expenses in connection with the conveyance of NYSTRS’s Company Interest to the ▇▇▇▇ Members (including, without limitation, transfer taxes payable in connection therewith) shall be borne by NYSTRS. In the event that the ▇▇▇▇ Members shall fail to deliver the ▇▇▇▇ Acceptance as aforesaid, the ▇▇▇▇ Members shall finally and conclusively be deemed to have declined to purchase NYSTRS’s Company Interest on the terms set forth in the NYSTRS Offer and the rights and privileges granted to the ▇▇▇▇ Members in this Section with regard to such NYSTRS Offer (as opposed to a subsequent NYSTRS Offer) shall be deemed null and void ab initio and of no further force or effect. Notwithstanding that the foregoing provision shall be self-operative and not in limitation thereof, in the event the ▇▇▇▇ Members do not deliver the ▇▇▇▇ Acceptance in accordance with the provisions of this Section, the ▇▇▇▇ Members shall, within ten (10) days after request by NYSTRS, execute and deliver to NYSTRS any document or instrument requested by NYSTRS in the exercise of NYSTRS’s reasonable judgment to confirm that all rights and privileges granted to the ▇▇▇▇ Members under this clause are null and void ab initio and of no further force or effect with regard to such NYSTRS Offer. In the event that the ▇▇▇▇ Members shall fail to execute and deliver any such document or instrument in such ten (10) day period, the ▇▇▇▇ Members hereby constitute and appoint NYSTRS attorney-in-fact, coupled with an interest, for the ▇▇▇▇ Members to execute and deliver any such instrument for and on behalf of the ▇▇▇▇ Members. Thereupon NYSTRS shall be entitled to sell the NYSTRS’s Company Interest to the proposed transferee upon the terms set forth in the NYSTRS Sale Material Terms. If such sale is not consummated within one (1) year from the date the NYSTRS Offer is first transmitted, then NYSTRS shall be obligated to again comply with the provisions of this Section 8.3(b) for any subsequent sale.

(c) No Transfer shall be made pursuant to this Section in any manner which would violate any provision of any mortgage or deed of trust encumbering all or any portion of the Properties.

(d) If NYSTRS or the ▇▇▇▇ Members, as the case may be, shall fail or refuse for any reason whatsoever to perform their obligations under this Section in the manner herein prescribed, the non-defaulting Member may pursue any of its rights and remedies as herein provided, or at law or equity, including, without limitation, the remedy of specific performance.

(e) Notwithstanding anything to the contrary set forth herein, in the event that any rights under this Section 8.3 shall be exercised prior in time to the exercise of any rights under Section 8.4 or Sections 8.6, 8.7 or 8.8 hereof, the rights under this Section 8.3 shall

-49-

supersede any other rights existing pursuant to Section 8.4 or Sections 8.6, 8.7 or 8.8 and in the event that any rights under Section 8.4 or Sections 8.6, 8.7 or 8.8 shall be exercised prior in time to the exercise of any rights under this Section 8.3, the rights under Section 8.4 or Sections 8.6, 8.7 or 8.8 shall supersede any other rights existing pursuant to this Section 8.3.

SECTION 8.4. Transfers by the ▇▇▇▇ Members.

(a) Notwithstanding any other term of this Agreement, the individual ▇▇▇▇ Members may, from time to time, in their sole discretion, Transfer all or any portion of their respective Company Interests to (x) any other Carr Member, or (y) any Affiliate, provided that such Affiliate shall assume the obligations to be performed by such ▇▇▇▇ Member hereunder.

(b) The ▇▇▇▇ Members may Transfer all of their Company Interests (i) at any time before or after the Lockout Date, to a new entity in connection with the merger, sale of all or substantially all of the assets of CarrAmerica or other business combination involving CarrAmerica in which the purchaser or survivor assumes CarrAmerica’s obligations, and where such entity assumes all of the obligations of the transferring ▇▇▇▇ Member hereunder, or (ii) after the Lockout Date, subject to the provisions of Section 8.4(c) hereof, to any person, firm, corporation or entity, provided that such entity assumes the obligations to be performed by the ▇▇▇▇ Members hereunder, and provided further that NYSTRS shall approve such Transfer pursuant to clause (ii), such approval not to be unreasonably withheld or delayed. In connection with such approval, NYSTRS shall be acting reasonably if NYSTRS refuses to grant approval because the proposed transferee or its Affiliate is an entity with which NYSTRS has engaged in litigation or has been engaged in a material dispute. Notwithstanding any other provision of this Agreement, no Transfer pursuant to Section 8.4(b)(i) on the part of the ▇▇▇▇ Members shall constitute a default or breach of this Agreement; it being understood that if such Transfer constitutes a Change in Control, certain rights are granted to NYSTRS hereunder.

(c) Should the ▇▇▇▇ Members desire to Transfer all of their Company Interests as permitted by Section 8.4(b)(ii), then the ▇▇▇▇ Members shall first deliver to NYSTRS an offer (the “▇▇▇▇ Offer”) to sell the ▇▇▇▇ Members Company Interests together with the material terms (the “▇▇▇▇ Sale Material Terms”), which shall be the same terms, including, without limitation, sales price, as offered to the proposed transferee by the ▇▇▇▇ Members in connection with the Transfer proposed under Section 8.4(b)(ii). NYSTRS shall have sixty (60) days from the receipt of ▇▇▇▇’▇ Notice, time being of the essence, to deliver a notice (the “NYSTRS Acceptance”) to the ▇▇▇▇ Members, in writing, that NYSTRS agrees to purchase the ▇▇▇▇ Members Company Interests on the ▇▇▇▇ Sale Material Terms in accordance with the provisions of this Section. In the event NYSTRS delivers the NYSTRS Acceptance as aforesaid, (i) the purchase and sale shall occur on the ▇▇▇▇ Sale Material Terms (provided, however, the closing shall occur no later than ninety (90) days from the date of the ▇▇▇▇ Offer), (ii) the ▇▇▇▇ Member shall deliver to NYSTRS at the closing of such purchase and sale, a duly executed, sealed and acknowledged instrument assigning to NYSTRS the ▇▇▇▇ Members Company Interests, which assignment shall be accompanied by such other documents and instruments, including, without limitation, corporate

-50-

resolutions, as may be requested by NYSTRS and the Company in the exercise of their reasonable judgment and (iii) on the effective date of such assignment, the Company shall deliver a release to the ▇▇▇▇ Members releasing the ▇▇▇▇ Members from all liabilities and obligations of the Company arising from and after the date of such assignment. Such assignment shall be free and clear of all liens and encumbrances, and the ▇▇▇▇ Members shall deliver to NYSTRS a written representation and warranty to such effect at the closing, which representation and warranty shall survive the closing. All costs and expenses in connection with the conveyance of the ▇▇▇▇ Members Company Interests to NYSTRS (including, without limitation, transfer taxes payable in connection therewith) shall be borne by the ▇▇▇▇ Members. In the event that NYSTRS shall fail to deliver the NYSTRS Acceptance as aforesaid, NYSTRS shall finally and conclusively be deemed to have declined to purchase the ▇▇▇▇ Members Company Interests on the terms set forth in the ▇▇▇▇ Offer and the rights and privileges granted to NYSTRS in this Section with regard to such ▇▇▇▇ Offer (as opposed to a subsequent ▇▇▇▇ Offer) shall be deemed null and void ab initio and of no further force or effect. Notwithstanding that the foregoing provision shall be self-operative and not in limitation thereof, in the event NYSTRS does not deliver the NYSTRS Acceptance in accordance with the provisions of this Section, NYSTRS shall, within ten (10) days after request by the ▇▇▇▇ Members, execute and deliver to the ▇▇▇▇ Members any document or instrument requested by the ▇▇▇▇ Members in the exercise of the Carr Member’s reasonable judgment to confirm that all rights and privileges granted to NYSTRS under this clause are null and void ab initio and of no further force or effect with regard to such ▇▇▇▇ Offer. In the event that NYSTRS shall fail to execute and deliver any such document or instrument in such ten (10) day period, NYSTRS hereby constitutes and appoints the ▇▇▇▇ Members attorneys-in-fact, coupled with an interest, for NYSTRS to execute and deliver any such instrument for and on behalf of NYSTRS; thereupon the ▇▇▇▇ Members shall be entitled to sell the applicable portion of the NYSTRS’s Company Interests to the proposed transferee upon the terms set forth in the ▇▇▇▇ Offer. If such sale is not consummated within one (1) year from the date the ▇▇▇▇ Offer is first transmitted, then the ▇▇▇▇ Members shall be obligated to again comply with the provisions of this Section 8.4(c) for any subsequent sale.

(d) No Transfer shall be made pursuant to this Section in any manner which would violate any provision of any mortgage or deed of trust encumbering all or any portion of the Properties.

(e) If NYSTRS or the ▇▇▇▇ Members, as the case may be, shall fail or refuse for any reason whatsoever to perform their obligations under this Section in the manner herein prescribed, the non-defaulting Member may pursue any of its rights and remedies as herein provided, or at law or equity, including, without limitation, the remedy of specific performance.

SECTION 8.5. New Members. Notwithstanding Sections 8.2, 8.3 and 8.4 hereof, no person or entity, not then a Member, shall become a Member hereunder under any of the provisions hereof unless such person or entity shall expressly assume and agree to be bound by all of the terms and conditions of this Agreement. Each such person or entity shall also cause to be delivered to the Company, at his or its sole cost and expense, a favorable opinion of legal

-51-

counsel acceptable to the Company in the exercise of its reasonable judgment, to the effect that (i) the contemplated Transfer of such Company Interest to such person or entity does not violate any applicable Federal or state law, and (ii) that such person or entity has the legal right, power and capacity to own the Company Interest. All reasonable costs and expenses incurred by the Company in connection with any Transfer of a Company Interest and, if applicable, the admission of a person or entity as a Member hereunder, shall be paid by the transferor. Upon compliance with all provisions hereof applicable to such person or entity becoming a Member, all other Members agree to execute and deliver such amendments hereto as are necessary to constitute such person or entity a Member of the Company.

SECTION 8.6. Sale of Properties; Right of First Offer. (a) From time to time after the Lockout Date (except as otherwise provided in this Agreement), either Member (the “Initiating Member”) may elect to cause the Company to sell any single Property (provided such Property has been in operation for at least 48 months), any one or more Subportfolios (in which case the 48 month operation requirement would not apply to any Property therein) or all of the Properties (the “Marketed Property”), by delivering written notice to the other Member (the “Responding Member”) of (i) its intention to market the Marketed Property, and (ii) the purchase price (the “Stipulated Price”) and other material terms (the “Sale Terms”) at which it believes the Company can sell the Marketed Property (the “Sale Notice”). All sales of Marketed Properties shall be all-cash sales; provided, however, that if feasible the Sale Terms may include the assumption by the purchaser of assumable financing. The material Sale Terms shall include, without limitation, the following: (i) the identity of the marketing agent for the Marketed Property (who shall not be a Member or an affiliate of a Member), and (ii) applicable brokerage fees and/or sales commissions. For purposes of this Section 8.6, the ▇▇▇▇ Members shall be considered a single Member.

(b) In the event the Initiating Member delivers the Sale Notice as aforesaid, the Responding Member shall have thirty (30) days for a single Property or one or more Subportfolios, and ninety (90) days for all the Properties, following the receipt of the Sale Notice, time being of the essence, to deliver a written notice (the “Response Notice”) to the Initiating Member, that the Responding Member agrees to purchase the Marketed Property at the Stipulated Price and on the Sale Terms, including the payment of (x) all existing Company debts (unless assumed) and liabilities related to the Marketed Property, and (y) any prepayment penalties or bank transfer charges actually incurred with regard to financing to be paid in full at closing or assumption fees paid in connection with assumed financing (pursuant to the terms of any mortgage encumbering the Marketed Property, without further negotiations with the holder of such mortgage) in connection with the exercise of the right contained in this Section 8.6 and such other terms and conditions as are usual and customary in all material respects. In the event the Responding Member delivers the Response Notice as aforesaid, (x) the purchase and sale shall occur on the Sale Terms and such other terms and conditions as are usual and customary in all material respects (provided, however, the closing shall occur no later than ninety (90) days from the date of the Responding Member’s Notice if the Marketed Property is a single Property or one or more Subportfolios and 150 days if the Marketed Property is all of the Properties), (y) the Company shall deliver to the Responding Member at the closing of such purchase and sale, a

-52-

duly executed, sealed and acknowledged special warranty deed conveying to the Responding Member the Marketed Property, which special warranty deed shall be accompanied by such other documents and instruments, including, without limitation, corporate resolutions, as may be requested by the Responding Member and the Company in the exercise of their reasonable judgment. The conveyance shall be subject to all encumbrances of record and assumed financing. All costs and expenses in connection with the conveyance of the Marketed Property to the Responding Member (including, without limitation, transfer taxes payable in connection therewith), not paid by the purchaser, shall be borne by the Company. In the event that the Responding Member shall fail to deliver the Response Notice as aforesaid, the Initiating Member may, but shall have no obligation to, cause the Company to sell the Marketed Property to any third party at no less than 95% of the Stipulated Price (or at a higher price) on the Sales Terms and such other terms and conditions as are usual and customary in all material respects (or on terms more beneficial to the Company) for a period of six (6) months thereafter. In the event that the Initiating Member shall elect to market the Marketed Property for sale to a third party in accordance with the previous sentence, the Responding Member shall have an opportunity to bid to purchase the Marketed Property along with other third parties. In the event that the Initiating Member shall fail to cause the Company to effectuate a sale of the Marketed Property pursuant to and in accordance with the provisions of this Section 8.6 within said six (6) month period, then the Initiating Member may exercise buy-sell rights with regard to the Property or Properties in question pursuant to Section 8.7, or, if the Marketed Property consists of all the Properties, the buy-sell rights with regard to the Company Interest of the Responding Member pursuant to Section 8.8. If the Initiating Member does not effect a sale within the six (6) month period and does not elect to exercise rights under Section 8.7, or, if respect to all the Properties, Section 8.8, then the Initiating Member shall once again be required to comply with the provisions of this Section 8.6 prior to effectuating a sale of the Marketed Property to a third party. In the event of a sale of the Marketed Property pursuant to the provisions of this Section 8.6, the Responding Member shall cooperate fully in the sale of the Marketed Property and shall execute and deliver any and all documents and instruments requested by the Initiating Member in the exercise of its reasonable judgment necessary or desirable to consummate such sale. If the Responding Member shall fail to execute and deliver any such document or instrument within ten (10) days after request therefor, the Responding Member shall be in default under this Agreement, and in addition to any other rights and remedies the Initiating Member may have hereunder, or at law or equity, the Responding Member hereby constitutes and appoints the Initiating Member attorney-in-fact, coupled with an interest, for the Responding Member to execute and deliver any such document or instrument for and on behalf of the Responding Member.

(c) No Transfer shall be made pursuant to this Section in any manner which would violate any provision of any mortgage or deed of trust encumbering all or any portion of the Properties.

(d) If NYSTRS or the ▇▇▇▇ Members, as the case may be, shall fail or refuse for any reason whatsoever to perform their obligations under this Section in the manner herein prescribed, the non-defaulting Initial Member may pursue any of its rights and remedies as

-53-

herein provided, or at law or equity, including, without limitation, the remedy of specific performance.

SECTION 8.7. Buy/Sell for Marketed Properties.

(a) After expiration of the six (6) month marketing period set forth in Section 8.6(b) with respect to one or more single Properties, one or more Subportfolios or all of the Properties, for a period of six (6) months thereafter, or at such other times or under such circumstances as may be otherwise permitted by this Agreement, either NYSTRS, on the one hand, or the ▇▇▇▇ Members acting as a group, on the other hand, may cause the Company to sell one or more single Properties, one or more Subportfolios, or all of the Properties, to a Member (the ▇▇▇▇ Members being considered a single Member) in accordance with this Section. One Member shall first give written notice to the Company (the “Property Call Notice”) of its intent to purchase one or more single Properties, one or more Subportfolios or all of the Properties (the “Buy- Sell Property”) from the Company. The Property Call Notice shall make reference to this Section and shall state (i) the purchase price for the Buy-Sell Property, which shall be all cash (provided that if feasible the sale terms may include the assumption by the purchaser of assumable financing) (the “Property Call Purchase Price”) that such Member shall be willing to pay for the Buy-Sell Property and (ii) a specified date for such purchase, which shall be no later than ninety (90) days if the Buy-Sell Property is a single Property or Properties or one or more Subportfolios or 150 days if the Buy-Sell Property is all of the Properties. The Member exercising such right and option and delivering the Property Call Notice to the Company shall hereinafter be referred to as the “Property Initiating Party.”

(b) In the event that the Property Initiating Party delivers the Property Call Notice as aforesaid, the other Member shall, by delivery of notice (the “Property Call Response Notice”) to the Property Initiating Party within thirty (30) days following the receipt of the Property Call Notice, time being of the essence, choose to (i) accept the Property Initiating Party’s offer to purchase the Buy-Sell Property for the Property Call Purchase Price, and on the date set forth in the Property Call Notice, or (ii) give notice to the Initiating Member that the other Member desires to purchase the Buy-Sell Property for the Property Call Purchase Price, and on the date set forth in the Property Call Notice. Failure to deliver the Property Call Response Notice within said thirty (30) day period shall be deemed to constitute an acceptance by the other Member of the Property Initiating Party’s offer to purchase the Buy-Sell Property for the Property Call Purchase Price, and on the date set forth in the Property Call Notice. In the event such other Member shall choose to purchase the Buy-Sell Property, then the Property Initiating Party shall be deemed to have approved the sale of the Buy-Sell Property to such other Member for the Property Call Purchase Price, and on the date set forth in the Property Call Notice.

(c) The closing of the purchase and sale of the Buy-Sell Property pursuant to the terms of this Section shall be held on the date provided in the Property Call Notice, at the office of the Company. At the closing (i) the Property Purchaser (hereinafter defined) shall pay

-54-

to the other Member the net proceeds (as a deemed contribution by the Property Purchaser and a deemed distribution to the other Member) that such other Member would have received if the Company had received the Property Call Purchase Price and distributed the net proceeds in accordance with Section 4.2 or Article IX, as applicable, such amount to be paid, by unendorsed certified or bank check or by wire transfer of immediately available federal funds, and (ii) the Company shall deliver to the Member purchasing the Buy-Sell Property (the “Property Purchaser”) a duly executed, sealed and acknowledged special warranty deed conveying to the Property Purchaser the Buy-Sell Property, which assignment shall be accompanied by such other documents and instruments, including, without limitation, corporate resolutions, as may be requested by the Property Purchaser and the Company in the exercise of their reasonable judgment. The Company and the Property Purchaser shall each pay their own legal fees in connection with the conveyance of the Buy-Sell Property pursuant to this Section and all other costs and expenses (including, without limitation, transfer taxes) shall be shared equally as between the Company and the Property Purchaser. The Property Purchaser shall pay all existing Company debts (except for assumed financing) and liabilities encumbering the Buy-Sell Property, any prepayment fees related to financing or assumption fees paid in connection with assumed financing.

(d) If either Member shall fail or refuse for any reason whatsoever to perform its obligations under this Section in the manner herein prescribed, the non-defaulting Member may pursue any of its rights and remedies as herein provided, or at law or equity, including, without limitation, the remedy of specific performance.

(e) The right to purchase as a Property Initiating Party set forth in this Section 8.7 may be exercised only by a Member that is not in default under Section 2.3 hereof.

(f) No conveyance shall be made pursuant to the provisions of this Section 8.7 if such conveyance would result in the violation of any provision contained in any mortgage or deed of trust encumbering all or any portion of the Properties.

SECTION 8.8. Buy/Sell for Member’s Interests.

(a) Pursuant to Sections 6.4, 6.14 or 6.15, or after expiration of the six-month marketing period set forth in Section 8.6(b) (and for a period of six-months thereafter), with respect to all of the Properties, either NYSTRS, on the one hand, or the ▇▇▇▇ Members acting as a group, on the other hand, shall have the right and option, exercisable upon the delivery of written notice to the other Member (the “Call Notice”) to purchase all of the Company Interests of the other Member, and NYSTRS or the ▇▇▇▇ Members, as the case may be, agree to sell such interests in accordance with the provisions of this Section. The Call Notice shall make reference to this Section and shall state (i) the purchase price (the “Call Purchase Price”) that such Member shall be willing to pay as a purchase price for all of the Properties and (ii) a specified date for such purchase, which such date shall be no later than 150 days after the delivery of the Call Notice. The Member exercising such right and option and delivering the Call Notice to the

-55-

other Member shall hereinafter be referred to as the “Initiating Party” and the other Member to whom the Call Notice shall be delivered shall hereinafter be referred to as the “Non-Initiating Party”. For purposes hereof (i) the “Initiating Party Call Purchase Price” shall mean the net proceeds that the Non- Initiating Party would receive upon a hypothetical sale of all of the Properties for the Call Purchase Price and a distribution of all of the proceeds thereof upon liquidation of the Company in accordance with Article IX, and (ii) the “Non-Initiating Party Call Purchase Price” shall mean the net proceeds that the Initiating Party would receive upon such a hypothetical sale/liquidation.

(b) In the event that the Initiating Party delivers the Call Notice as aforesaid, the Non-Initiating Party shall, by delivery of notice (the “Call Response Notice”) to the Initiating Party within thirty (30) days following the receipt of the Call Notice, time being of the essence, choose to (i) accept the Initiating Party’s offer to purchase the Non-Initiating Party’s Company Interests for the Initiating Party Call Purchase Price, and on the date set forth in the Call Notice, or (ii) purchase the Initiating Party’s Company Interests for the Non-Initiating Party Call Purchase Price, and on the date set forth in the Call Notice. Failure to deliver the Call Response Notice within said thirty (30) day period shall be deemed to constitute an acceptance by the Non-Initiating Party of the Initiating Party’s offer to purchase the Non-Initiating Party’s Company Interests for the Initiating Party Call Purchase Price, and on the date set forth in the Call Notice. In the event the Non-Initiating Party shall choose to purchase the Initiating Party’s Company Interest pursuant to the terms of this Section, the Initiating Party shall be obligated to sell its Company Interests to the Non-Initiating Party for the Initiating Party Call Purchase Price, and on the date set forth in the Call Notice.

(c) The closing of the purchase and sale of the Company Interests of the Member selling its Company Interests pursuant to the terms of this Section (the “Seller”) shall be held on the date provided in the Call Notice, at the office of the Company, or at such other location as NYSTRS and the ▇▇▇▇ Members shall find mutually agreeable. At the closing (i) the Seller shall receive, by unendorsed certified or bank check payable to the order of the Seller or its designee, or, at the Seller’s election, by wire transfer of immediately available federal funds to an account designated by the Seller, an amount equal to the Initiating Party Call Purchase Price or the Non-Initiating Party Call Purchase Price, as the case may be, (ii) the Seller shall deliver to the Member purchasing the Seller’s Company Interest (the “Purchaser”) a duly executed, sealed and acknowledged instrument assigning to the Purchaser the Seller’s Company Interest, which assignment shall be accompanied by such other documents and instruments, including, without limitation, corporate resolutions, as may be requested by the Purchaser and the Company in the exercise of their reasonable judgment and (iii) on the effective date of such assignment, the Company shall deliver a release to the Seller releasing the Seller from all liabilities and obligations of the Company arising from and after the date of such assignment. Such assignment shall be free and clear of all liens and encumbrances, and the Seller shall deliver a written representation and warranty to such effect at the closing, which representation and warranty shall survive the closing. Each Member shall pay its legal fees in connection with the conveyance of Company Interests pursuant to this Section and all other costs and expenses (including, without

-56-

limitation, transfer taxes) shall be shared by the Members in accordance with their Company Interests.

(e) The right to purchase as an Initiating Party set forth in this Section 8.8 may be exercised only by a Member that is not in default under Section 2.3 hereof.

(f) No Transfer shall be made pursuant to the provisions of this Section 8.8 if such Transfer would result in the violation of any provision contained in any mortgage or deed of trust encumbering all or any portion of the Properties.

(g) In lieu of purchasing a Member’s Company Interest pursuant to the procedure set forth in Section 8.8, the transaction may be accomplished through a redemption of the Company Interests of the Seller by the Company.

SECTION 8.9. First Right to Invest. Except as set forth below, until the earlier of (i) the date that CarrAmerica is no longer a Member of the Company or (ii) the occurrence of a Change of Control not resulting in a liquidation of the Company, the Company shall have the first right to invest (which right shall be exercised by NYSTRS within thirty (30) days after notice from CarrAmerica) in any property located in the following submarkets, which property CarrAmerica intends to invest in directly or contribute and/or sell to a joint venture in which CarrAmerica will retain an interest: (a) Las Colinas, Dallas, Texas; (b) northwest Austin, Texas (except for the Braker site); (c) north suburban Chicago, Illinois; and (d) the Panorama/Dry Creek submarket, Denver, Colorado (except for the Dry Creek Corporate Center site). The Company shall not have the foregoing right to invest in the case of (i) an investment in a property to be leased to an existing CarrAmerica tenant, a “build-to-suit” project or an expansion of an existing project in which the Company has not previously made an investment, or (ii) the contribution or sale of multiple properties to such a joint venture where the value of the properties in such submarkets represents less than twenty percent (20%) of the aggregate value of all properties to be contributed or sold to such joint venture.

ARTICLE IX

TERMINATION

SECTION 9.1. Dissolution. Except as hereinafter provided to the contrary, the Company shall be dissolved and its business wound up upon the happening of any of the following events, whichever shall first occur:

(a) the sale, condemnation or other disposition of all or substantially all of the Properties and the receipt of all consideration therefor;

-57-

(b) at any time that there are no Members; provided that the Company shall not be dissolved if within ninety (90) days after the occurrence of the event that terminated the continued membership of the last remaining Member, the personal representative of the last remaining Member agrees in writing to continue the Company and to the admission of such personal representative or its nominee or designee to the Company as a Member effective as of the occurrence of the event that terminated the continued membership of the last remaining Member;

(d) The occurrence of any event, other than those referred to in paragraph (b), which causes dissolution of a limited liability company under the Delaware Act.

SECTION 9.2. Termination. Notwithstanding any other provision of this Agreement, in all cases of dissolution of the Company, the business of the Company shall be wound up and the Company terminated as promptly as practicable thereafter, and each of the following shall be accomplished:

(a) The Liquidating Member shall cause to be prepared a statement setting forth the assets and liabilities of the Company as of the date of dissolution, a copy of which statement shall be furnished to all of the Members.

(b) The property and assets of the Company shall be liquidated by the Liquidating Member as promptly as possible, but in an orderly and businesslike and commercially reasonable manner. The Liquidating Member may, in the exercise of its business judgment and if commercially reasonable, determine to defer the sale of all or any portion of the property and assets of the Company if deemed necessary or appropriate to realize the fair market value of any such property or assets.

(c) The proceeds of sale and all other assets of the Company shall be applied and distributed as follows and in the following order of priority:

(i) To the payment of (x) the debts and liabilities of the Company (including any outstanding amounts due on any recourse indebtedness encumbering the Property, or any part thereof) and (y) the expenses of liquidation, other than liabilities for distribution to Members under Section 18-601 or 18-604 of the Delaware Act.

(ii) Except as provided in this Agreement, to Members and former Members in satisfaction of liabilities for distribution under Section 18-601 or 18-604 of the Delaware Act.

-58-

(iii) To the setting up of any reserves which the Liquidating Member shall determine to be reasonably necessary for contingent, unliquidated or unforeseen liabilities or obligations of the Company or the Members arising out of or in connection with the Company. Such reserves may, in the discretion of the Liquidating Member, be paid over to a national bank or national trust company selected by it and authorized to conduct business as an escrowee to be held by such bank or trust company as escrowee for the purposes of disbursing such reserves to satisfy the liabilities and obligations described above, and at the expiration of such period as the Liquidating Member may reasonably deem advisable, distributing any remaining balance as provided in clause (iv) below.

(iv) To the Members in accordance with the provisions of Section 4.2; provided, however, that no distribution shall be made that creates or increases a Capital Account deficit for any Member which exceeds such Member’s obligation (deemed or actual) to restore such deficit, determined as follows: Distributions shall first be determined tentatively pursuant to Section 4.2 without regard to the Member’s Capital Account, and then the allocation provisions of Section 5 shall be applied tentatively as if such tentative distributions had been made. The actual distribution to such Member pursuant to this Section 9.2(c)(iv) shall be equal to (x) in the case of a Member that has no deficit Capital Account after such tentative distributions and allocations have been made, the tentative distribution to such Member, and (y) in the case of a Member that has a deficit Capital Account after such tentative distributions and allocations are made, the tentative distribution to such Member less the amount of the deficit.

(v) The balance, if any, to the Members, in accordance with and to the extent of the Members’ ending positive Capital Account balances, after giving effect to all contributions, distributions and allocations for all periods, including, without limitation, any allocations of Profits or Losses from any Capital Transactions causing or resulting in the dissolution and termination of the Company.

Distributions pursuant to the preceding clauses (iv) and (v) shall be made by the end of the Fiscal Year during which the dissolution of the Company occurs (or, if later, within ninety (90) days of such dissolution).

(b) Without limiting the foregoing, the Liquidating Member shall, upon the dissolution and upon completion of the winding up of the affairs of the Company, file appropriate certificate(s) to such effect in the proper governmental office or offices under the

Delaware Act as then in effect. Notwithstanding the foregoing, each Member, upon the request of the Liquidating Member, shall promptly execute, acknowledge and deliver all such documents, certificates and other instruments as the Liquidating Member shall reasonably request to effectuate the proper dissolution and termination of the Company, including the winding up of the business of the Company.

SECTION 9.4. No Redemption. The Company may not acquire, by purchase, redemption or otherwise any Company Interest of any Member, except as otherwise provided by Section 8.8.

SECTION 9.5. No Distribution in Kind. The Company may not distribute Company Assets to the Members in kind without the approval of all of the Members.
