          (c) Any change in Percentage Interests pursuant to this Section 3.03(b) shall not affect the amount of any Partner’s Capital Contributions for purposes of determining the amount to which such Partner is entitled pursuant to Section 5.02(a), to the extent attributable to Section 5.02(a).

     3.04 Capital Accounts.

          (a) The Company shall establish and maintain a separate Capital Account for each Partner in accordance with the following provisions:

               (i) To each Partner’s Capital Account there shall be credited (A) the amount of money contributed by such Partner to the Company, (B) the fair market value of property contributed by such Partner to the Company (net of any liabilities secured by such property that the Company is considered to assume or take subject to under Code Section 752) (the Partners agreeing that the fair market value of the Properties contributed by the General Partner to the Partnership on the date of this Agreement have fair market values equal to their Gross Asset Value as set forth in Section 3.01), and (C) such Partner’s distributive share of Profits and any items in the nature of income or gain which are specially allocated to such Partner pursuant to ARTICLE IV; and

               (ii) To each Partner’s Capital Account there shall be debited (A) the amount of money distributed to such Partner by the Company, (B) the fair market value of any

- 16 -

Company Asset distributed to such Partner by the Company (net of any liabilities secured by such Asset that such Partner is considered to assume or take subject to under Code Section 752), and (C) such Partner’s distributive share of Losses and any items in the nature of expenses or losses which are properly allocated to such Partner pursuant to any Section of ARTICLE IV.

     The foregoing provisions 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 General Partner shall determine that it is prudent to modify the manner in which the Capital Accounts, or any debits or credits thereto, are computed in order to comply with such Regulations, the General Partner may make such modification, provided that it will not have any adverse effect on the amounts distributable to any Partner pursuant to this Agreement. The General Partner also shall (1) make any adjustments that are necessary or appropriate to maintain equality between the combined Capital Accounts of the Partners and the total amount of Company capital reflected on the Company’s balance sheet, as computed for book purposes in accordance with Regulations Section 1.704-1(b)(2)(iv)(g), and (2) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Regulations Section 1.704-1(b) subject, however, to the limitation on modifications having any adverse effect on amounts to be distributed to a Partner as provided in the preceding sentence. Any questions with respect to a Partner’s Capital Account shall be resolved by the General Partner in its reasonable discretion, applying principles consistent with this Agreement.

          (b) Any transferee of a portion or all of a Partner’s Partnership Interest shall succeed to the Capital Account of the transferor Partner to the extent it relates to the Partnership Interest transferred.

     3.05 Negative Capital Accounts. Except to the extent Partners are required to make contributions to the capital of the Company under Section 3.01 and Section 3.02, no Partner shall be required to pay to the Company or to any other Partner any deficit or negative balance which may exist in such Partner’s Capital Account from time to time or upon Liquidation of the Company. A negative Capital Account shall not be considered a loan from or an asset of the Company.

     3.06 Return of Capital; No Interest on Amounts in Capital Account. Except upon dissolution of the Company or as may be expressly set forth in this Agreement, no Partner shall have the right to demand or receive the return of any of its aggregate Capital Contributions or any part of its Capital Account or be entitled to receive any interest on its Capital Contributions or its outstanding Capital Account balance.

ARTICLE IV

ALLOCATIONS

     4.01 Allocation of Profits and Losses.

          (a) After giving effect to the allocations required by Section 4.03 of this Agreement, if any, and subject to the other limitations in this ARTICLE IV, Profits and Losses

- 17 -

for any taxable year of the Partnership shall be allocated to the Capital Accounts of the Partners so as to produce, as nearly as possible, Capital Account balances for the Partners (taking into account all prior allocations and distributions) which equal the amount to which the Partners would be entitled as a liquidating distribution from the Partnership upon a hypothetical liquidation in which the net proceeds were distributed in accordance with the priorities set forth in Section 5.02 and as if the net proceeds available for distribution were an amount equal to the aggregate positive balance in the Partners’ Capital Accounts computed after taking into account all allocations of Profits and Losses (or items thereof) for the taxable year, including those pursuant to this Section 4.01.

          (b) If the allocation of all or any portion of Partnership Losses for a taxable year (or items thereof) would cause or increase a negative balance in the Adjusted Capital Account of any Limited Partner, such Loss (or item thereof) shall be allocated to those Limited Partners, if any, having positive remaining Adjusted Capital Account balances. Any remaining amount of such Partnership Losses (or items thereof) shall be allocated 100 percent (100%) to the General Partner.

     4.02 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), notwithstanding any other provision of this ARTICLE IV, if there is a net decrease in Company Minimum Gain with respect to any Fiscal Year, each Partner shall be specially allocated items of Company income and gain for such Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such Partner’s share of the net decrease in Company Minimum Gain, determined in accordance with Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. 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 4.03(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), notwithstanding any other provisions of this ARTICLE IV, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any Fiscal Year, each Person 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 Company income and gain for such 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). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 4.02(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.

- 18 -

          (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), (5) or (6), items of Company income and gain shall be specially allocated to 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 4.02(c) shall be made if and only to the extent that such Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this ARTICLE IV have been tentatively made as if this Section 4.02(c) were not in this Agreement.

          (d) In the event any Partner has a deficit Capital Account at the end of any Company Fiscal Year which is in excess of the sum such Partner is obligated, or is deemed to be obligated, to restore pursuant to the next-to-last sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 4.02(d) shall be made if and only to the extent that such Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in this ARTICLE IV have been tentatively made as if this Section 4.02(d) and Section 4.02(c) were not in this Agreement.

          (e) In the event that the Profits available to be allocated to the Partners for any Fiscal Year pursuant to Section 4.01 are less than the maximum amount otherwise allocable to them pursuant thereto, then there shall be specially allocated to the Partners items of Company income and gain equal to such maximum amount.

          (f) Nonrecourse Deductions for any Fiscal Year or other period shall be specially allocated among the Partners in the same manner as if they were Losses for such Year or period.

          (g) 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).

          (h) To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is required pursuant to Regulations Sections 1.704-1(b)(2)(iv)(m) (2) or (4) to be taken into account in determining Capital Accounts as the result of a distribution to a Partner in complete liquidation of such Partner’s interest in the Company, the amount of such adjustment to the 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 specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be so adjusted.

     4.03 Curative Allocations. The allocations set forth in Section 4.02, other than Section 4.02(e) (the “Regulatory Allocations”), are intended to comply with certain requirements of the Regulations. 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

- 19 -

of Company income, gain, loss, or deduction pursuant to this Section 4.03. Therefore, notwithstanding any other provision of this ARTICLE IV (other than the Regulatory Allocations), the General Partner shall make such offsetting special allocations of Company 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 this Agreement and all Company items were allocated pursuant to Sections 4.01, and 4.04. In exercising its discretion under this Section 4.03, the General Partner shall take into account future Regulatory Allocations under Sections 4.02(a) and (b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Sections 4.02(f) and 4.02(g).

     4.04 Other Allocation Rules.

          (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 determined by the General Partner using any permissible method under Code Section 706 and the 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 Partners in the same proportions as they share Profits and Losses, as the case may be, for the year.

     4.05 Tax Allocations: Code Section 704(c). In accordance with Code Section 704(c) and the 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 Partner 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 (computed in accordance with the definition of “Gross Asset Value” above). In the event the Gross Asset Value of any Company asset is adjusted pursuant to any provision of this Agreement in accordance with such definition, subsequent allocations of income, gain, loss and deduction with respect to such asset shall take into account any variation between the adjusted basis of such asset for Federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder. Any elections or other decisions relating to such allocations shall be made by the General Partner in accordance with the “Traditional Method” described in Regulations Section 1.704-3(b). Allocations pursuant to this Section 4.05 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 or other items, or distributions pursuant to any provision of this Agreement.

ARTICLE V

DISTRIBUTIONS

     5.01 Net Cash Receipts. Subject to year end adjustments based on annual audit contemplated at Section 8.04 below and in the definition of Net Operating Cash Receipts, and

- 20 -

the corresponding adjustment of distributions as soon as practicable after such audit, Net Cash Receipts (including, without limitation, Extraordinary Cash Flow from Capital Transactions that do not constitute a Liquidating Sale – e.g., the sale of one or more, but less than all, of the Properties) shall be distributed by the Company to the Partners in proportion to their Percentage Interests [The confidential material contained herein has been omitted and has been separately filed with the Commission.], by wire transfer to an account as directed from time to time by each of the Partners. Concurrently with each such distribution the General Partner shall provide to each Partner an explanation of the sources of such Net Cash Receipts, detailed on a Property-by-Property basis.

     5.02 Cash Flow from Liquidating Sale. Except as provided in Section 5.03, Extraordinary Cash Flow from a Liquidating Sale shall be distributed by the Company in the following order of priority:

          (a) First, to the Partners until the Partners have received distributions pursuant to this Section 5.02(a) equal to the amount of their Unreturned Capital Contributions (and in the same proportion as the Unreturned Capital Contribution of a Partner bears to the aggregate Unreturned Capital Contributions of all Partners) until the Unreturned Capital Contribution amount of each Partner equals $0.00;

          (b) Next, to the Partners in the amount needed to cause the aggregate distributions to meet the Unleveraged IRR Target amount, and in the same proportion as the Percentage Interests of the Partners at the time of the distribution.

          (c) Next, the balance, if any, [The confidential material contained herein has been omitted and has been separately filed with the Commission.]% to NYSCRF and [The confidential material contained herein has been omitted and has been separately filed with the Commission.]% to the General Partner; provided, however, that if such balance consists, in whole or in part, of Extraordinary Cash Flow from New Development Properties, Redevelopment Properties or Vacant Land Properties (as determined in accordance with the allocation rules set forth in the definition of Unleveraged Development IRR) (such portion of the balance being referred to herein as the “Development Portion”), then the Development Portion shall instead be distributed as follows if either of the following conditions is met: [The confidential material contained herein has been omitted and has been separately filed with the Commission.]

     5.03 Distributions on Liquidation. If prior to a Liquidating Sale the Company shall have undergone one or more Capital Transactions with respect to which the Extraordinary Cash Flow would have been eligible, if it had been received in a Liquidating Sale as of the date of such Capital Transaction, for distribution pursuant to Section 5.02(c), then, upon the subsequent occurrence of an actual Liquidating Sale, the Partners shall re-calculate the Partners’ respective distributions of Extraordinary Cash Flow resulting from such Capital Transaction or Capital Transactions pursuant to Section 5.02 rather than Section 5.01, and NYSCRF shall pay to the General Partner a sum (the “True-up Sum”) equal to that portion of the distributions made to NYSCRF on account of such Capital Transaction or Capital Transactions which is to be re-allocated to the General Partner pursuant to this Section 5.03. Notwithstanding any provision in this Agreement which might otherwise operate to limit the liability of a Partner for any other purpose, such provision shall not limit the liability of NYSCRF for its obligation to pay the True-

- 21 -

up Sum in accordance with the provisions of this Section 5.03. NYSCRF shall be personally liable for the True-up Sum.

     5.04 Distributions in Kind. All distributions shall be made in cash and no Company assets shall be distributed in kind without the consent of all of the Partners except as provided in Section 10.02(a). Any assets distributed in kind shall be valued for such purpose at their fair market value as of the date of distribution as determined by an independent appraiser selected by the General Partner with the approval of NYSCRF, and shall be treated for the purposes of this ARTICLE V as if the Company had sold such assets at such value and distributed the proceeds of such sale to the Partner or Partners receiving such assets.

     5.05 REIT Distributions. At the option of the General Partner, the Company shall take, and the General Partner is authorized to take, reasonable action which in the opinion of tax counsel selected by the General Partner and reasonably acceptable to NYSCRF, is necessary and consistent with the General Partner’s (or its Affiliate’s) qualification as a REIT, to distribute sufficient amounts pursuant to this ARTICLE V to enable the General Partner to pay shareholder dividends that will (i) enable the General Partner to satisfy the requirements for qualifying as a REIT under the Code and Regulations; and (ii) enable the General Partner (or its Affiliate that is a REIT) to avoid any material federal income or excise tax liability of the General Partner (or its Affiliate that is a REIT) as a result of its status as a REIT, assuming for purposes of this determination that the only items on the federal income tax return of the General Partner (or such Affiliate that is a REIT) are the items shown on its Schedule K-1 received from the Company and all cash distributions received from the Company (less a reasonable allowance for non-deductible administrative costs) have been paid as dividends to the shareholders of the General Partner on the day after such distributions are received from the Company. Any distribution made pursuant to this Section 5.05 shall be made to all Partners in accordance with ARTICLE V. In no event shall NYSCRF incur any cost or expense as a result of this Section 5.05.

     5.06 Offsets.

          (a) Provided that the Manager under the Management and Leasing Agreement is an Affiliate of the General Partner, then in the event that any amounts due from the Manager to the Company under the Management and Leasing Agreement are unpaid and overdue, NYSCRF may cause the Company, after notice to the Manager, to offset the unpaid portion of such amounts claimed against the Manager against amounts due to the General Partner under this Agreement, and further provided that if there is any dispute between the Manager and the Company or NYSCRF as to whether the claim against the Manager is valid, the amount sought to be withheld shall be escrowed until the first to occur of the matter being resolved or the Manager, after written notice from the Company, no longer contesting the validity of the claim, with the interest earned thereon being paid to the party who is ultimately determined to be entitled to the amount claimed or, if it is determined that each party is entitled to a portion of the amount in dispute, pro rata based on the amount paid to each.

          (b) Provided that the Development Manager under the Development Management Agreement is an Affiliate of the General Partner, then in the event that any amounts due from the Development Manager to the Company under the Development Management Agreement are unpaid and overdue, NYSCRF may cause the Company, after notice to the

- 22 -

Development Manager, to offset the unpaid portion of such amounts claimed against the Development Manager against amounts due to the General Partner under this Agreement, and further provided that if there is any dispute between the Development Manager and the Company or NYSCRF as to whether the claim against the Development Manager is valid, the amount sought to be withheld shall be escrowed until the first to occur of the matter being resolved or the Development Manager, after written notice from the Company, no longer contesting the validity of the claim, with the interest earned thereon being paid to the party who is ultimately determined to be entitled to the amount claimed or, if it is determined that each party is entitled to a portion of the amount in dispute, pro rata based on the amount paid to each.

          (c) Provided that the General Partner is an Affiliate of LPLP, in the event that NYSCRF obtains a final non-appealable judgment against LPLP under the Contribution Agreement that is not paid when due, NYSCRF may cause the Company to offset the unpaid portion of such judgment against amounts due to the General Partner under this Agreement.

ARTICLE VI

- 24 -

          (b) NYSCRF is an investor only and shall have no right to participate in the management or control of the business or affairs of the Company, or to sign for or bind the Company; provided, however, that NYSCRF shall have the approval rights set forth in Section 6.04 and elsewhere in this Agreement.

     6.02 Delegation; Standards; Indemnification.

          (a) Subject to the terms of this Agreement, the General Partner may, at any time, delegate any of its powers, duties and responsibilities to an Affiliate. Any delegation pursuant to this Section 6.02(a) shall not, however, relieve the General Partner of any of its obligations hereunder.

          (b) The Company shall enter into, or cause its Subsidiary that owns Property to enter into:

               (i) a Development Management Agreement with the General Partner or its Affiliate to oversee the construction and development of each New Development and each Redevelopment; and

               (ii) a Management and Leasing Agreement with the General Partner or its Affiliate to cover the management and leasing of each Property owned, directly or indirectly, by the Partnership. The management fees, leasing commissions and finders’ fees payable for the services shall be as set forth in the Management and Leasing Agreement provided that such fees shall not at any time exceed the then current market rates for such services in the area in which the affected Property is located. Notwithstanding the foregoing, in the event that lender approval is not obtained for the assumption of any of the Assumed Financing prior to the contribution or sale of the applicable Entity to the Company, the then-existing management agreement for such Entity (the “Existing Management Agreement”) shall remain in place and effective until such approval is obtained or such Assumed Financing is paid off, defeased or refinanced; provided, however, that as between the “Manager” and the “Owner” under such Existing Management Agreement, the fees and obligations set forth in the form of Management and Leasing Agreement attached hereto as Exhibit B shall control. By executing this Agreement on behalf of the General Partner, LPLP hereby consents to and agrees to be bound by the immediately preceding sentence.

          (c) It is the intention of the Partners that, to the extent feasible, all other actions taken on behalf of the Company shall be taken by the General Partner or its authorized delegates, subject to the provisions of this Agreement and the approval rights of NYSCRF pursuant to Section 6.04.

          (d) The General Partner shall perform its duties hereunder with the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims, for the exclusive benefit and protection of the Company, except that the General Partner shall not be required to diversify the Company’s assets.

          (e) In the performance of its duties and responsibilities and the exercise of its right, power, authority and discretion under this Agreement:

- 25 -

               (i) the General Partner shall act solely in the interests of the Company; and

               (ii) neither the General Partner nor any Affiliate of the General Partner shall (A) deal with the assets of the Company in its own interests or for its own account; (B) in any capacity act in any transaction involving the Company on behalf of any party whose interests are adverse to the interests of the Company; or (C) receive any compensation or consideration for its own personal account from any party dealing with the Company or proposing to deal with the Company in connection with a transaction involving any portion or all of the Property (other than fees for the rendering of maintenance services to the Properties as approved in the Annual Business Plan, provided that the cost of such services will be reimbursed to the General Partner at a rate equal to the General Partner’s direct costs for those services, plus a reasonable allocation of overhead related to providing such services).

          (f) The Company (but not any Partner) shall indemnify, defend and hold harmless the General Partner and the trustees, officers, directors and employees of the General Partner and its Affiliates (collectively the “Indemnified Party”) in the event it 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 by reason of any acts or omissions, or alleged acts or omissions, arising out of the activities of the Indemnified Party on behalf of the Company, or in furtherance of the interests of the Company, against any and all costs, losses, damages or expenses of any nature whatsoever for which such Indemnified Party has not otherwise been reimbursed (including attorneys’ fees, judgments, fines and accounts paid in settlement) actually and reasonably incurred by the Indemnified Party in connection with such action, suit or proceeding so long as the Indemnified Party reasonably believed that its actions were within the scope of this Agreement and the Indemnified Party did not act fraudulently or in bad faith or in a manner constituting negligence or willful misconduct or in breach of the standards set forth in Section 6.02(d), or violate securities laws or criminal laws. The termination of any action, suit or proceeding by judgment, order, settlement or upon a plea of nolo contendere or its equivalent shall not of itself (except insofar as such judgment, order, settlement or plea shall itself specifically provide) create a presumption that the Indemnified Party acted fraudulently or in bad faith or acted in a manner constituting negligence or willful misconduct. The indemnification rights of the Indemnified Party set forth in this Section 6.02(f) shall be cumulative of and in addition to, any and all rights, remedies, and recourse to which it shall be entitled whether pursuant to the provisions of this Agreement, at law, or in equity.

          (g) To the extent permitted by applicable law and except as otherwise provided in this Agreement, the General Partner shall not be answerable for the default or misconduct of any third party agent, investment advisory service, attorney, appraiser, consultant, contractor, engineer, real estate managing agent, accountant or bookkeeper if such Person is not an Affiliate of the General Partner and if selected by the General Partner with reasonable care, unless the General Partner knowingly participates in such wrongdoing, has actual knowledge thereof and fails to take reasonable remedial action, or through negligence in the performance of its own specific responsibilities under this Agreement has enabled such wrongdoing to occur.

          (h) Neither the Company nor any Partner shall have any claim against the General Partner by reason of any act or omission of the General Partner, nor against NYSCRF by

- 26 -

reason of any act or omission of NYSCRF, except where such claim is based on gross negligence, actual fraud, material, deliberate or willful breach of this Agreement, or intentional tortious misconduct. Notwithstanding anything to the contrary contained herein or in any other agreement executed in connection herewith, but subject to the last sentence of Section 5.03, the General Partner expressly agrees that NYSCRF shall not be liable personally or otherwise for any breach or default by NYSCRF under this Agreement or any other agreement executed in connection with this Agreement, except to the extent of, and only to the extent of, the NYSCRF’s Partnership Interest in the Company. Except only for NYSCRF’s Partnership Interest in the Company, no assets of NYSCRF may be liened, encumbered, attached, levied or executed upon to satisfy any liability of or judgment against NYSCRF arising out of this Agreement or any other agreement executed in connection with this Agreement.

     6.03 Annual Business Plan. The Annual Business Plan shall be the blue print for the management of the business of the Company. The Annual Business Plan for calendar year 2007 is attached hereto as Exhibit E. No later than [The confidential material contained herein has been omitted and has been separately filed with the Commission.], and each [The confidential material contained herein has been omitted and has been separately filed with the Commission.] thereafter, the General Partner shall prepare and deliver to NYSCRF for its review and approval a proposed Annual Business Plan for the next Fiscal Year. NYSCRF shall, within [The confidential material contained herein has been omitted and has been separately filed with the Commission.] days after receipt, provide the General Partner with written comments thereto, and if the Annual Business Plan for the succeeding year is not previously agreed to, the parties shall meet no later than [The confidential material contained herein has been omitted and has been separately filed with the Commission.] of the then current year to agree on such Annual Business Plan. If for any reason at the beginning of any year the Annual Business Plan for such year has not been agreed to, the Company shall continue to operate in accordance with the Annual Business Plan for the prior year, except that [The confidential material contained herein has been omitted and has been separately filed with the Commission.]. Each Annual Business Plan shall, among other information, contain the following information, consistent with the form attached hereto as Exhibit E:

          (a) a summary of the conditions of the leasing, sales and development marketplace in the DC Metropolitan Area (and the General Partner shall forward to NYSCRF copies of marketing reports prepared by third-party real estate firms received by the General Partner summarizing the conditions of leasing and development in the marketplace for commercial office properties in which the various portions of the Property are located);

          (b) the annual operating budget, which shall include the estimated revenues and expenses (including debt service), any anticipated Call for Capital pursuant to Section 3.02(a) and the regular capital expenditures, all for the ensuing Fiscal Year, and a leasing plan for each of the Properties (which leasing plan shall include any proposed changes to the standard form lease; tenant requirements and rental rates; estimated improvements; costs of re-tenanting; leasing commissions; and other non-recurring extraordinary capital expenditures, if any, for the affected Property);

          (c) the amounts of proposed reserves and contingency funds;

- 27 -

          (d) the recommendation of the General Partner with respect to debt financing to be issued by the Company in the ensuing Fiscal Year;

          (e) the recommendation of the General Partner with respect to the sale of any one or more of the Properties in the ensuing Fiscal Year

          (f) the recommendation of the General Partner with respect to any New Developments to be initiated in the ensuing Fiscal Year, together with a summary of all ongoing development activities under any Development Management Agreements then in effect, and a proposed development budget for all such recommended and ongoing projects; and

          (g) such additional information as may be necessary or appropriate to fully inform the Partners of all matters relevant to the Company and, if their approval is required, to enable the Partners to make an informed decision with respect to their approval of such Plan, or as any Partner shall reasonably have requested;

          (h) and whenever necessary to reflect a material change in any of the information contained in the Annual Business Plan as last submitted to NYSCRF, the General Partner shall submit such changes to NYSCRF for its approval, and upon such approval, such amended Plan shall become the Annual Business Plan.

     6.04 Matters Requiring Approval of NYSCRF. In addition to any other matter pertaining to the Company set forth herein that requires the approval of NYSCRF and in addition to the right of NYSCRF pursuant to Section 6.18, the following actions or decisions with respect to or affecting the Company or Company’s assets shall require the approval of NYSCRF prior to any action by the General Partner (except to the extent that the matter in question is included in, and budgeted for or permitted by, other than in the case of Section 6.04(k), the then applicable Annual Business Plan):

[The confidential material contained herein has been omitted and has been separately filed with the Commission.]

- 28 -

     6.05 Hazardous Materials. The General Partner shall not knowingly conduct or authorize and shall use its reasonable efforts to prevent a release of Hazardous Materials at any of the Properties and shall promptly notify NYSCRF in writing of any pending or threatened investigation or inquiry by any governmental authority in connection with any Hazardous Materials relating to a Property or of the occurrence of a release of Hazardous Materials at any Property. The General Partner shall promptly notify NYSCRF in writing if the General Partner becomes aware of any release of Hazardous Materials in violation of law originating on the Property, or of any such release originating in a neighboring property that threatens the Property.

     6.06 Emergency Actions. In the event that it is necessary to make expenditures which are not provided for in the Annual Business Plan, or to take any other action which requires the approval of NYSCRF under Section 6.04, but which is required under emergency court order, executive order or legislation, or which the General Partner, in good faith, believes appropriate in an emergency to avoid risk to life or health or facilitate the preservation of any portion or all

- 30 -

of the Company’s assets, and the General Partner reasonably determines that there is insufficient time to obtain such approval and that any delay in making such expenditures or taking such action could result in a violation of law or materially adversely affect the value of the Company assets or could materially increase the risk to life or health, then the General Partner shall be authorized to bind the Company for any expenditures or in any other action taken on behalf of the Company in such emergency. The General Partner shall notify NYSCRF of any exercise of its power and authority under this Section as soon as practicable thereafter.

     6.07 Regular Meetings.

          (a) The Partners shall meet annually at a time and place determined by the General Partner and reasonably approved by NYSCRF, for a report on the current Fiscal Year’s activities, a review of the most recent financial statements and, when available, a presentation of the next Fiscal Year’s Annual Business Plan, as well as to consider and decide such matters as may be specified by the General Partner or by prior written notice from any Partner to the General Partner. Without limiting the foregoing, the annual meetings shall include a discussion and analysis of (i) anticipated acquisitions and development activities for the ensuing year, and (ii) whether the Company should continue to hold or should sell each Property and any changes in the projected period of continuing to hold any portion or all of the Property. Reasonable notice shall be provided to the Partners of the time and place of such meeting and the matters to be decided or discussed. Any proposal requiring action of the Partners shall be provided to the Partners a minimum of ten (10) business days prior to such meeting. Participation in meetings may be by means of conference telephone call or similar telecommunications whereby all individuals participating in the meeting can hear, and speak to, each other at the same time.

          (b) Voting shall take place at meetings, provided, however, that any Partner may, at any time and without a meeting therefor, notify the General Partner of its vote on any matter requiring such vote, and the General Partner shall tabulate the vote and notify the Partners of such vote promptly thereafter. Voting under this Agreement shall take place in writing and the General Partner shall thereafter confirm the result of the vote of the Partners on any matter in writing.

          (c) Any action which may be taken by the Partners at any meeting may be taken without a meeting pursuant to written consent of all of the Partners.

     6.08 Special Meetings. Any Partner may call a special meeting of the Partners at any time. All of the provisions set forth above with respect to regular meetings shall also apply to any special meetings.

     6.09 Third Parties. Notwithstanding anything to the contrary contained herein, the General Partner may execute a certificate that, except in the case of any matter which requires the approval of NYSCRF pursuant to Section 6.04, may be conclusively relied upon by any third party (without any further inquiry whatsoever) stating that any action or proposed action does not require the approval or consent of the Partners under this Agreement or that such approval or consent has been obtained, and any action taken by the General Partner in connection therewith shall in fact be the act of, and bind, the Company. The foregoing shall not relieve the General Partner from any liability it may have to the Company or the Partners if, in fact, such action or

- 31 -

proposed action did require the approval or consent of any Partner and such consent or approval was not obtained.

     6.10 Other Activities of Partners. Any Partner and its Affiliates may have other business interests and may engage in other business ventures of any nature or description whatsoever, whether presently existing or hereafter created, and whether or not competitive with the business of the Company or any Partner, provided, however, that during the term of this Agreement the General Partner and its Affiliates shall not acquire or own any office property in the DC Metropolitan Area, except as permitted in ARTICLE XIII below. The rights of NYSCRF under this Section 6.10 are personal to NYSCRF and shall not be enforceable by any assignee or transferee, whether voluntarily or involuntarily or by operation of law, of the rights of NYSCRF under this Agreement, other than a transferee of NYSCRF pursuant to Section 10.02(b).

     6.11 Withholding of Tax on Certain Company Distributions.

          (a) Unless treated as a Tax Payment Loan, any amount paid by the Company for or with respect to any Partner on account of any withholding tax or other tax payable with respect to the income, profits or distributions of the Company pursuant to the Code, the Regulations or any state or local statute, regulation or ordinance requiring such payment (a “Withholding Tax Act”) shall be treated as a distribution to such Partner for all purposes of this Agreement, consistent with the character or source of the income, profits or cash that gave rise to the payment or withholding obligation. To the extent that the amount required to be remitted by the Company under the Withholding Tax Act exceeds the amount then otherwise distributable to such Partner, unless and to the extent that funds shall have been provided by such Partner pursuant to the last sentence of this Section 6.11(a), the excess shall constitute a loan from the Company to such Partner (a “Tax Payment Loan”). Any such Tax Payment Loan shall be payable upon demand and shall bear interest, from the date that the Company makes the payment to the relevant taxing authority, at the lesser of: (i) the Prime Rate plus two percentage points per annum, or (ii) the highest rate permitted by applicable law, compounded monthly (but in no event higher than the highest interest rate permitted by applicable law). During such time as any Tax Payment Loan to any Partner (or the interest thereon) remains unpaid, all future distributions otherwise to be made to such Partner under this Agreement shall be distributed for such Partner’s account by applying the amount of any such distributions first to the payment of any unpaid interest on such Tax Payment Loan and then to the repayment of the principal thereof, and no such future distributions shall be paid to such Partner until all of such principal and interest has been paid in full, but all such amounts shall, for purposes of this Agreement, be treated as a distribution to such Partner. If the amount required to be remitted by the Company under the Withholding Tax Act exceeds the amount then otherwise distributable to a Partner, the Company shall notify such Partner at least five (5) Business Days in advance of the date upon which the Company would be required to make a Tax Payment Loan under this Section 6.11(a) (the “Tax Payment Loan Date”) and provide such Partner the opportunity to pay to the Company on or before the Tax Payment Loan Date, all or a portion of such deficit. If any Tax Payment Loan is not fully repaid before the earlier of (a) removal of the Partner receiving the Tax Payment Loan, or (b) liquidation of the Company, such Partner shall remit any remaining portion of the principal and interests payable on the Tax Payment Loan to the Company.

- 32 -

          (b) The General Partner shall have the authority to take all actions necessary to enable the Company to comply with the provisions of any Withholding Tax Act applicable to the Company and to carry out the provisions of this Section 6.11. Nothing in this Section 6.11 shall create any obligation on the General Partner to advance funds to the Company or to borrow funds from third parties in order to make any payments on account of any liability of the Company under a Withholding Tax Act.

     6.12 Unrelated Business Taxable Income. The General Partner shall use commercially reasonable efforts to avoid taking any action which it knows or reasonably should know would (a) cause any indebtedness of the Company to not qualify for the exception to “acquisition indebtedness” under Code Section 514(c)(9)(A), or (b) otherwise cause NYSCRF to have a substantial risk of recognizing UBTI (assuming, for this purpose, that NYSCRF is an organization subject to the tax imposed by Code Section 511(a)(1)), provided that any transaction which General Partner determines will create UBTI for NYSCRF shall require NYSCRF’s prior approval. By way of example and without limiting the generality of the foregoing, the General Partner shall use its best efforts to ensure that:

          (a) With respect to any lease executed on behalf of the Company:

               (i) The determination of the amount of rent shall not be expressed in whole or in part as a percentage of the income or profits derived by the lessee from the space leased (other than an amount based on a fixed percentage or percentages of gross receipts or gross sales);

               (ii) Not more than ten percent (10%) of the rent shall be expressly attributable to personal property, determined at the time the personal property is placed in service by the lessee (and not by reference to any allocation contained in the lease documents);

               (iii) If subleasing is permitted, the Company may not share in any net profit derived by the tenant from any sublease, and the tenant thereunder may not sublease all or any portion of its leasehold interest in violation of paragraph (i);

               (iv) No services shall be performed for the tenant other than services usually or customarily rendered to tenants in connection with office space; and

               (v) All tenant payments under the lease shall be designated as “rent” or “additional rent”.

          (b) The General Partner shall not engage in, or cause the Company to engage in, any activity that would cause all or any part of the Property to be considered stock in trade or other property of a kind which would properly be includable in inventory if on hand at the close of the taxable year or property held primarily for sale to customers in the ordinary course of a trade or business of the Company. NYSCRF acknowledges that a decision to sell or otherwise dispose of any property of the Company may cause the Company to engage in commercially reasonable sales activities and the Company and the General Partner are authorized to engage in such activities with respect to Company property to the extent that such sale is authorized or permitted under this Agreement.

- 33 -

          (c) With respect to any indebtedness incurred by the Company:

               (i) The price for any acquired or improved real property will be fixed at the time of the acquisition of the property or the time of the completion of any such improvement;

               (ii) The amount of any indebtedness or any other amount payable with respect to such indebtedness, or the time for making any payment of any such amount, shall not be dependent, in whole or in part, upon any revenue, income, or profits derived from such real property;

               (iii) Any property acquired by the Company will not be subsequently leased to the seller or to any person who bears a relationship to such seller that is described in Code Section 267(b) or 707(b);

               (iv) Any property of the Company will neither be acquired from nor leased to a person that bears a relationship to the Limited Partner or the Company which is described in subparagraph (C), (E) or (G) of Code Section 4975(e)(2) or a person that bears a relationship, which is described in subparagraph (F) or (H) of Code Section 4975(e)(2), to any person described in subparagraph (C), (E), or (G) of Code Section 4975(e)(2);

               (v) The Company will not incur indebtedness from any person described in Sections 6.12(c)(iii) or 6.12(c)(iv) in connection with any acquisition or any improvement to property; and

               (vi) The provisions of this Section 6.12(c) are intended to comply with the requirements of Code Section 514(c)(9)(B) and should be construed thusly.

     With respect to the foregoing: (A) NYSCRF acknowledges that the requirements of Section 6.12(a) above are satisfied with respect to all existing leases of space in the Properties in effect as of the date of this Agreement and with respect to the standard forms of “Multi-Tenant Office Lease” and “Single-Tenant Office Lease” generally utilized by Affiliates of the General Partner, copies of which the General Partner has previously provided to NYSCRF; and (B) the General Partner shall notify NYSCRF of any proposed changes in the structure or operation of the Company not set forth in the Annual Business Plan that might cause the Company or NYSCRF to incur UBTI, and such change shall not be made without the prior approval of NYSCRF.

     6.13 Prohibited Transactions.

          (a) The General Partner shall use best efforts to avoid taking action which it knows or reasonably should know would constitute a prohibited transaction (within the meaning of Code Section 4975(c)) and would cause NYSCRF (assuming, for this purpose, that NYSCRF is a “plan” within the meaning of Code Section 4975(e)(1)) or any Person who is a disqualified person (within the meaning of Code Section 4975(e)(2)) with respect to NYSCRF to incur a tax under Code Section 4975, without NYSCRF’s prior approval.

- 34 -

          (b) Notwithstanding any other provisions of this Agreement, other than Section 6.13(a), or any non-mandatory provision of the Act, any action of the General Partner on behalf of the Company or any decision by the General Partner to refrain from acting on behalf of the Company, based on an opinion of tax counsel selected by the General Partner and reasonably acceptable to NYSCRF that such action or omission is necessary or advisable in order to: (i) protect the ability of Liberty Property Trust, a Maryland real estate investment trust which is the general partner of the sole member of Liberty Washington Venture, LLC, to continue to qualify as a REIT under the Code, or (ii) avoid Liberty Property Trust incurring any material taxes under Section 857 or Section 4981 of the Code, is expressly authorized under this Agreement and is deemed approved by all of the Partners.

          (c) At any time when a direct or indirect beneficial interest in the Company is owned by an entity that has elected to be taxed as a REIT under the Code, neither the Company nor any Subsidiary shall without the prior written consent of Liberty: (i) acquire any asset that is not described in Section 856(c)(4)(a) of the Code or any successor provision; (ii) enter into a loan secured by an interest in real property in which the Company would receive income from a “shared appreciation provision” as defined in Section 856(j)(5) of the Code; (iii) enter into a loan in which the interest income depends, directly or indirectly, in whole or in part, on the income or profits of any person for purposes of Section 856(f) of the Code; (iv) enter into any lease involving real property where any portion of the rents would be excluded from the definition of “rents from real property” under Section 856(d)(2) of the Code; or (v) sell any property which, when sold, would constitute property described in Section 1221(1) of the Code, except when the net selling price is less than $10,000. Notwithstanding the foregoing, if any of the provisions of Sections 856 or 857 of the Code are amended so that one of the requirements in clauses (i) through (v) above becomes irrelevant to the qualification of a REIT as a REIT under the Code and will not cause adverse tax consequences to a REIT if the requirement is not complied with, such provision shall no longer apply to the Company.

          (d) In making any determinations under this Agreement in which the classification of any entity as a “real estate investment trust” for federal income tax purposes is relevant, such determination or calculation shall be made by assuming that only the items reported on such entity’s federal income tax return are the items reported on the Partner’s Schedule K-1 received from the Company (or the entity’s distributive share of such items).

     6.14 Deemed Approval. NYSCRF shall be deemed to have approved and the General Partner shall not have any liability or responsibility under either Section 6.12 or Section 6.13, to the extent that the action which caused the Company or NYSCRF to incur UBTI or which constituted a prohibited transaction (a) received the approval of NYSCRF where such approval is required under this Agreement, or (b) resulted from the Company’s failure to take any action proposed by the General Partner and submitted to NYSCRF, if such failure was because such proposed action did not receive the approval of NYSCRF.

     6.15 Reporting Requirements. In addition to any other reporting obligations of the General Partner contained in this Agreement, the General Partner shall:

          (a) (1) notify NYSCRF of any material fire or other material damage to the Property, and in such event, arrange for an insurance adjuster reasonably acceptable to NYSCRF

- 35 -

to view the Property before repairs are started, but in no event shall Manager settle any losses, complete loss reports, adjust losses or endorse loss drafts in excess of $250,000 without NYSCRF’s prior consent; and (2) promptly notify NYSCRF after the General Partner becomes aware of any significant personal injury or property damage occurring to or claimed by any tenant or third party on or with respect to the Property;

          (b) notify NYSCRF of the commencement of any action, suit or proceeding against NYSCRF, or against Manager with respect to the operations of the Property, or otherwise affecting the Property, other than routine tort claims covered by insurance;

          (c) on or before the 15^th day of each month, prepare and submit to NYSCRF a progress report on leasing activities at the Property for the preceding period, such report to be in the format customarily used by the General Partner and its Affiliates for its own portfolio; and

          (d) notify NYSCRF when the General Partner receives written notice of any material violation of law at any portion of the Property, as well as provide NYSCRF with evidence that the non-compliance has been remedied.

     6.16 Action by Partners. Except as otherwise provided in this Agreement, any action required or permitted to be taken by the Partners shall require the unanimous consent or approval of the Partners, unless otherwise required by the Act.

     6.17 Right to Disclose Information. The General Partner shall not be in breach of its obligations under this Agreement or any other obligations or duties to NYSCRF at law or in equity (whether under a theory of fiduciary duty or otherwise) if the General Partner or its Affiliates files this Agreement (and some or all of the exhibits hereto) as an exhibit to a filing it may make with the Securities Exchange Commission or makes disclosures regarding the transactions governed by this Agreement to the extent the General Partner or its Affiliates reasonably believe necessary to enable the General Partner or its Affiliates to comply with federal and state securities laws and the regulations of the Securities Exchange Commission, the rules of any stock exchange, or in connection with any filing or registration made by Liberty Property Trust, an Affiliate of the General Partner, as the issuer of publicly traded securities, or as part of information provided to its investors and/or financial analysts.

     6.18 Contracts with Affiliates. NYSCRF, acting alone, shall have the right on behalf of the Company to send any notice of default or termination, to institute or settle legal proceedings and/or to take such other action as may be necessary or appropriate to enforce the rights and protect the interests of the Company pursuant to any agreement with the General Partner or an Affiliate of the General Partner or with respect to any other rights or remedies of the Company running against or in connection with the General Partner or Affiliate of the General Partner.

     6.19 Loan Provisions.

          (a) Each Partner shall, in its reasonable discretion, cooperate to amend this Agreement and the Certificate of Limited Partnership if required to comply with the requirements of any lender providing mortgage financing to the Company in accordance with this Agreement.

- 36 -

          (b) The Partners acknowledge that the Liberty Loan was provided to the Company, and that (with the consent of NYSCRF, as set forth in Section 6.04(l)) future financing may be provided to the Company or any Entity, and/or serviced by an Affiliate of the General Partner (the “Affiliate Lender”). As a result, the interests of the Affiliate Lender, in its capacity as a lender, may be different from, or in conflict with, the interests of the Partners or the interests of the Company or any of their respective Affiliates. In recognition of the foregoing and in consideration of the Affiliate Lender providing or facilitating any such loan, the Partners acknowledge and agree that the Affiliate Lender is and will be entitled to enforce its rights under any existing or future loan (and ancillary security) documents with the Company and/or any Entity and will be entitled to pursue any and all remedies to which it is entitled (including calling a default under, accelerating or foreclosing on any collateral securing, such loan) even if doing so would be detrimental to or create a conflict with the Company and/or such Entity or any of its Partners, and each of the Partners waives, to the fullest extent permitted by law, (i) any right to object to such enforcement, (ii) any right to assert a claim against the General Partner or its Affiliates as a result of such conflict of interest, and (iii) any claim for a breach of fiduciary duty, duty of loyalty, lender liability, equitable subordination or other claims relating to or arising from the fact that the Affiliate Lender and its Affiliates would have an interest, directly or indirectly, as both a creditor and a Partner of the Company. In addition, the classification and treatment for income tax purposes of the Liberty Loan and any other financing provided by an Affiliate of the General Partner as non-recourse debt or non-recourse liability shall be made and governed by the Code.

     6.20 Project Financing.

          (a) The Partners expect that the Company will obtain, or cause certain of the Entities to obtain, debt financing in such amounts, from such lenders, with such security and on such terms and conditions as shall be determined in accordance with this Agreement (collectively with the Assumed Financing, the “Project Financing”).

          (b) All Project Financing will be non-recourse to the Company and to all Partners, except that the General Partner may elect, in its sole discretion, to provide one or more guarantors (the “Guarantors”) acceptable to the lender to be personally liable for: (i) fraud, environmental liability, misapplication of tenant security deposits and other types of liabilities (collectively the “Non-Recourse Carve Outs”) to be set forth in the documents and instruments evidencing the Project Financing, pursuant to provisions acceptable to the Guarantors; and/or (ii) for such other liabilities, if any, under the loan as the Guarantors may elect in their sole discretion, pursuant to documents acceptable to the Guarantors. The personal obligations of the Guarantors as set forth in such loan documents are referred to herein as the “Recourse Obligations.” The Partners confirm that LPLP serves as the Guarantor of the Recourse Obligations with respect to the Assumed Financing and, with respect to the Assumed Financing for WillowWood I-II, Liberty Property Trust also serves as a Guarantor of the Recourse Obligations.

          (c) With respect to all sums that at any time may be paid by a Guarantor on account of the Recourse Obligations, the Partners agree that: (i) the Company shall indemnify, defend and hold the Guarantor harmless from and against all such liabilities and all costs and expenses arising therefrom, (ii) NYSCRF shall indemnify, defend and hold the Guarantor

- 37 -

harmless from and against all such liabilities and all costs and expenses arising from the gross negligence, actual fraud, material, deliberate and willful breach of this Agreement, or intentional tortious misconduct of NYSCRF that triggers liability under the Recourse Obligations, and (iii) the Guarantor shall be subrogated to the rights of the holder of the Project Financing with respect thereto; provided, however, that the foregoing provisions of (i) and (ii) above shall not apply to any liabilities, costs or expenses of the Guarantor resulting from its or its Affiliate’s gross negligence, actual fraud, material, deliberate or willful breach of this Agreement, its guaranty of the Recourse Obligations or any other documents evidencing the Project Financing, or intentional tortious misconduct; and provided further that subrogation rights of the Guarantor shall be totally subordinated in all respect to the rights of the holder of the Project Financing and shall not be enforceable until satisfaction of all obligations of the Company and the borrower Entity under the Project Financing.

          (d) At any time while the Recourse Obligations are outstanding in whole or in part, the Company shall not be authorized to take, and the General Partner shall not permit the Company or any Entity to take, any action that would result in the triggering of liability under the Non-Recourse Carve Outs, without the prior written consent of the Guarantors, which may be withheld for any reason or no reason. Without limiting the generality of the foregoing, without the consent of the Guarantors, the Company and the Entity shall not be authorized to commence and the General Partner shall not commence, any voluntary proceeding for bankruptcy, reorganization or similar relief, and shall not consent to any involuntary petition for such relief if such action would trigger any liability under the Recourse Obligations. The Partners expressly waive any rights that they may have at any time, whether under a theory of fiduciary duty or under any other legal or equitable principle, to compel the Partnership or the Entity to commence a voluntary bankruptcy proceeding or themselves to initiate an involuntary bankruptcy proceeding, or to assert any claims against the General Partner or its Affiliates for the failure to file a voluntary proceeding.

     6.21 Title Holding Subsidiaries. Title to each Property may be held by a separate, single purpose, limited liability company or partnership that is wholly owned by, and whose only members, partners and/or managers are, the Company and other limited liability companies wholly owned (directly or indirectly) by the Company (each a “Title Holding Subsidiary”). It shall be the General Partner’s duty and responsibility to duly form and maintain each Title Holding Subsidiary and cause each Title Holding Subsidiary to be and remain in good standing in its state of organization and qualified to do business in each jurisdiction in which it owns property or otherwise conducts business, to obtain appropriate employer and/or tax identification numbers (to the extent required) for the Title Holding Subsidiary, and the like. The rights, duties, responsibilities and authority of the Partners with respect to Title Holding Subsidiaries and Properties owned through a Title Holding Subsidiary shall be identical to their respective rights, duties, responsibilities and authority with respect to the Company and Properties owned directly by the Company. Any provision of this Agreement giving the Partners the right or authority to take any action or refrain from taking any action, or cause the Company to take any action or refrain from taking any action, shall be interpreted to give them the identical right or authority with respect to the appropriate Title Holding Subsidiary. Any provision of this Agreement imposing any duty or responsibility on the Partners, or limiting their respective rights or authority, with respect to Properties owned directly by the Company shall be interpreted to impose the identical duty, responsibility or limitation on them with respect to Properties owned

- 38 -

through a Title Holding Subsidiary. The operating agreement for each Title Holding Subsidiary shall be in a form approved by the Partners.

     6.22 Ratification of Recitals. The Recitals set forth on Exhibit H to this Agreement are incorporated herein by reference. The Partners hereby ratify and consent to the transactions described in the Recitals to this Agreement.

ARTICLE VII

COMPENSATION OF PARTNERS; PAYMENT OF COMPANY EXPENSES

     7.01 Compensation from Company. The Company shall pay to the General Partner (or its Affiliate) the sum of [The confidential material contained herein has been omitted and has been separately filed with the Commission.] annually as an administrative fee in compensation for the General Partner’s services required hereunder. Except as aforesaid and as provided in Section 7.02, no Partner shall receive any compensation from the Company for any services rendered in its capacity as a Partner. Nothing contained herein shall prevent (i) a Partner from receiving reasonable compensation for any services rendered to the Company in a non-Partner capacity or from receiving distributions under ARTICLE V, (ii) the General Partner or its Affiliate from receiving fees pursuant to the Development Management Agreement, or (iii) the General Partner or its Affiliate from receiving fees for managing or leasing all or a portion of the Property pursuant to the Management and Leasing Agreement.

     7.02 Company Expenses.

          (a) The Management and Leasing Agreement shall require the General Partner or its Affiliate, at its expense and without reimbursement from the Company, to provide the Company with adequate personnel and office space and all necessary office furnishings and equipment and shall pay the salaries and other compensation of such personnel and the cost of telephone service, heat and other utilities and other items of an overhead and administrative nature.

          (b) The Company shall bear all other costs and expenses incurred in connection with the management and operation of the business and affairs of the Company, or in carrying out the business, purposes, and objectives of the Company, including without limitation, costs associated with a proposed transaction that is not consummated for any reason whatsoever. Without limiting the foregoing, the Company shall bear the costs of all third-party vendors who provide services to the Company (including without limitation auditors, tax consultants and attorneys). Subject to Sections 6.04(a) and 6.04(b) to the extent the General Partner or its Affiliates are able to provide such services to the Company, the General Partner may (subject to the prior approval of NYSCRF) provide such service to the Company, and the Company will compensate the General Partner or its Affiliates at a level that will reimburse the direct costs of those services, plus a reasonable allocation of overhead related to providing such services.

ARTICLE VIII

COMPANY BOOKS, RECORDS AND STATEMENTS

     8.01 Books and Records. The General Partner shall establish and maintain accurate, full and complete Company records and books of account showing assets, liabilities and the Capital Accounts of the Partners, revenues and expenditures, and all other aspects of the operations, transactions and cash flows of the Company in accordance with generally accepted accounting practices and principles consistently applied.

          (i) NYSCRF shall have the right, at its sole expense, to cause an audit of the records of the Company to be conducted by accountants selected by NYSCRF.

The Tax Matters Partner shall manage audits of the Company conducted by the Internal Revenue Service or other governmental agency pursuant to the audit procedures under the Code and the regulations issued thereunder, provided that the Tax Matters Partner shall not settle any matter with the Internal Revenue Service or other governmental agency without the consent of NYSCRF, which consent shall not be unreasonably withheld. The Company, through the Tax Matters Partner, is authorized to cooperate with and to monitor the Internal Revenue Service in any audit that the Internal Revenue Service may conduct of the Company’s books and records and information or other returns filed by the Company. The Tax Matters Partner shall take all actions necessary to preserve the rights of the Partners with respect to audits and shall provide the Partners with any notices of such proceedings and other information as required by law. The Tax Matters Partner shall keep the Partners timely informed of its activities under this Section. The Company, through the Tax Matters Partner, may similarly cooperate with and monitor any audit by any other governmental authority and prepare and file protests or other appropriate responses to such audits. All costs incurred in connection with the foregoing activities, including legal and accounting costs, shall be borne by the Company. Any additional expenses with respect to judicial review of adverse determinations in connection with any such tax audits or the defense of any Partner against any claim asserted by the Internal Revenue Service or other tax authority of additional tax liability arising out of its ownership of its interest in the Company shall be borne by the Partner who wishes to proceed with such judicial review or defense. Unless otherwise expressly prohibited or restricted pursuant to this Agreement, the Tax Matters Partner may make, refrain from making, or revoke any and all tax elections which it may deem appropriate, in its sole discretion, on behalf of the Company.

          (c) Neither the Company nor any Partner shall take any action that would result in the Company being taxed as other than a “partnership” for federal income tax purposes, including (but not limited to) electing to be taxed as other than a “partnership” by making such an election on Form 8832, “Entity Classification Election.”

     8.07 Certain Elections.

          (a) In the event that a distribution of any of the Company’s assets is made in the manner provided in Code Section 734, where a transfer of an interest in the Company permitted by this Agreement is made in the manner provided in Code Section 743, or in any other circumstance permitting an election to be made under Section 754 of the Code, then, upon the request and at the expense of any Partner, the Company shall file an election under Code Section 754, in accordance with procedures set forth in the applicable Regulations. The Partners’ Capital Accounts shall be adjusted in accordance with Regulations Section 1.704-1(b)(2)(iv)(m). Each Partner shall provide the Company with all information necessary to give effect to any election under Code Section 754.

          (b) In the event of any change in the Code or Regulations which could affect any Partner and with respect to which the Company may elect to either have such change apply, or not apply, then the Company will make such election or not make such election in a manner that the tax provisions contained in this Agreement shall remain in effect unless all of the Partners agree that the Company should make such election or not make such election in another

- 43 -

manner; provided, however, that if NYSCRF (at its expense) obtains an opinion, from recognized tax counsel selected by NYSCRF and reasonably satisfactory to the General Partners, that solely on account of the Company’s making the election or the Company’s failing to make the election will (based upon the assumptions set forth in Section 6.12) cause (i) the allocations to NYSCRF under ARTICLE IV to be UBTI, (ii) NYSCRF no longer to be a “qualified organization” (within the meaning of Code Section 514(c)(9)(C)), or (iii) any indebtedness of the Company to not qualify for the exceptions to “acquisition indebtedness” under Code Section 514(c)(9)(A), then the Company shall make such election or refrain from making such election in the manner specified by NYSCRF, and the Partners shall promptly modify this Agreement in a manner to maintain as nearly as possibly the same economic effect on the Partners as would have existed had such election been made or not been made, as the case may be, to the maximum extent permitted by applicable law, but in no event shall such change have a negative economic impact on the General Partner.

          (c) ERISA Representations. NYSCRF, in connection with representations made or that may be made to one or more Lenders regarding the status of the Company as not being an employee benefit plan as defined in ERISA, and regarding the Company’s assets not being considered to be “plan assets” pursuant to certain Department of Labor Regulations, represents and warrants to the Company and the General Partner that NYSCRF is a governmental plan as defined in section 3(32) of ERISA.

ARTICLE IX

     9.03 Remedies Reserved. Upon any Default by any Partner, such Partner shall no longer have the right to vote on, consent to, approve or otherwise take part in any decision of the Partners, and, in addition, the other Partners shall each have the rights and remedies specified herein as well as those available to non-defaulting Partners as a matter of law or equity; provided, however, that if the defaulting Partner is the General Partner, then it shall continue to have all of the management rights of the General Partner under this Agreement, and provided further than if the default by the General Partner constitutes fraud, the General Partner’s management of the affairs of the Company shall be subject to the reasonable oversight of the Advisor.

TRANSFER OF PARTNERSHIP INTERESTS;
SALE OF PROPERTY

     10.01 Transfer.

          (a) The term “Transfer,” when used with respect to a Partnership Interest, shall include any direct or indirect sale, assignment, gift, bequest, succession through intestacy, pledge, hypothecation, mortgage, exchange, or other disposition, except that such term shall not include: (i) any pledge or mortgage of a Partnership Interest or other hypothecation of or granting of a security interest in a Partnership Interest in connection with any financing obtained by or on behalf of the Company and approved pursuant to Section 6.04(l) of this Agreement, or (ii) the sale, issuance, assignment, gift, bequest, succession through intestacy, pledge, hypothecation, mortgage, exchange, or other disposition of shares of beneficial interest in Liberty Property Trust or of limited partnership units in Liberty Property Limited Partnership (or their respective successors through merger, consolidation or sale of all or substantially all of the assets or beneficial interests). For purposes of the foregoing, a change in the trustee of any trust that is a Partner or an Affiliate of any Partner shall not be treated as a Transfer.

          (b) Except as provided in Section 10.02, no Partner may Transfer its Partnership Interest, in whole or in part, directly or indirectly, without the approval of the other Partners and, if required by any loan documents entered into by the Company, any third party lender. Any Transfer or purported Transfer of any Partnership Interest not made in accordance with the foregoing shall be null and void and in breach of this Agreement.

- 45 -

     10.02 Approved Transfers.

          (a) Anything in Section 10.01 to the contrary notwithstanding, the General Partner may, without the consent of the other Partner, undergo a Transfer, in whole but not in part: [The confidential material contained herein has been omitted and has been separately filed with the Commission.]

          (b) Anything in Section 10.01 to the contrary notwithstanding, NYSCRF may, without the consent of the other Partner [The confidential material contained herein has been omitted and has been separately filed with the Commission.]

          (c) Upon any Transfer undertaken in accordance with Section 10.02, the transferring Partner shall promptly deliver to the non-transferring Partner (i) an assignment and assumption agreement, in form and substance reasonably acceptable to the non-transferring Partner, whereby the transferring Partner assigns, and the transferee accepts and assumes, all of the transferring Partner’s rights, obligations and liabilities hereunder, and (ii) the other instruments contemplated by Sections 10.04(b)-(f); provided the requirements of Section 10.04(a) shall not apply to any such Transfer. Upon the delivery to the non-transferring Partner of the instruments referenced in clauses (i) and (ii) above, if the transfer results in a new Partner (as opposed to the acquisitions of interests in the existing Partner), the transferring Partner shall withdraw from the Company in accordance with Section 10.03 and be released from all liability hereunder, and the transferee shall be deemed admitted as a Partner pursuant to Section 10.04 and shall be deemed to have assumed all of the rights, duties, obligations and liabilities of the transferring Partner under this Agreement.

          (d) Anything in this Section 10.02, or otherwise in this Agreement, to the contrary notwithstanding, no Transfer or assignment of a Partnership Interest shall be made (i) if such Transfer is effectuated through an “established securities market” or a “secondary market” (or the substantial equivalent thereof) within the meaning of Section 7704 of the Code or such Transfer causes the Company to be taxed as a “publicly traded partnership” as such term is defined in Sections 469(k)(2) or 7704(b) of the Code; or (ii) if such Transfer, in the opinion of counsel selected by the General Partner and reasonably acceptable to NYSCRF, would not allow Liberty Property Trust to continue to be taxed as a REIT under the Code or would subject Liberty Property Trust to any material taxes under Sections 857 or 4981 of the Code..

     10.03 Withdrawal of a Partner. A Partner may voluntarily withdraw from the Company only upon a Transfer of all of such Partner’s Partnership Interest in accordance with this

- 46 -

ARTICLE X. If any Partner withdraws from the Company in violation of this Agreement, it shall not be entitled to any distributions from the Company as a result of such withdrawal, but shall remain entitled to those distributions it would be entitled to receive had the withdrawal not occurred.

     10.04 Admission of Transferee as a Partner. Any Person to whom all of a Partnership Interest has been transferred pursuant to Section 10.01(b) or Section 10.02 shall be admitted as a substituted Partner as a result of such transfer to the extent of the Partnership Interest so transferred only upon the satisfaction of all of the following conditions:

          (a) The unanimous approval of the other Partners, provided however, that no Partner shall unreasonably withhold its approval to any transferee becoming a substituted Partner if such transferee in the reasonable judgment of the General Partner has (together with any guarantor of its obligations) a net worth sufficient to fund any outstanding obligations it might have under this Agreement and expressly agrees in writing to fulfill such obligations;

          (b) Such transferee’s written acceptance of, and written agreement to be bound by, all of the terms and provisions of this Agreement;

          (c) Reasonable evidence of the authority of such transferee to become a Partner and to be bound by all of the terms and provisions of this Agreement;

          (d) The approval of any third party lender if required by any loan documents entered into by the Company;

          (e) An opinion of counsel reasonably satisfactory to counsel for the Company that such transfer, and the transferee’s participation in the Company as a Partner, will not (A) adversely affect the status of a Partner as a REIT (if it is not the transferor), or (B) violate any then applicable Federal or other securities laws or the rules and regulations of the Securities and Exchange Commission or the securities commission of any other jurisdiction; and

          (f) The satisfaction of such additional requirements as any Partner may reasonably determine to assure itself that neither it nor the Company will incur any new or additional liability or obligation as a result of such transfer or purchase.

Anything herein to the contrary notwithstanding, any transferee who does not become a substituted Partner shall be only entitled to receive the share of Profits, Losses and distributions of the Company to which the transferor was entitled with respect to the Partnership Interest so transferred, and shall not have any right to vote on, consent to, approve or otherwise take part in any decision of the Partners, or to any of the other rights associated with the ownership of such Partnership Interest.

     10.05 Admission of Additional Partners. Notwithstanding anything to the contrary contained in this Agreement, no Person may be admitted as an additional Partner without the unanimous approval of each the Partners, which approval may be withheld in the sole discretion of such Partner.

ACQUISITIONS, NEW DEVELOPMENTS AND REDEVELOPMENTS

     13.01 Exclusive Operations Except as expressly provided for in this ARTICLE XIII, neither the General Partner nor its Affiliates shall, directly or indirectly, purchase, develop or redevelop office properties within the DC Metropolitan Area.

     13.02 Yield Parameters. The Company’s initial yield parameters are summarized in Exhibit I. Modification of these parameters shall be subject to the approval of both the General Partner and NYSCRF.

     13.03 New Acquisitions.

          (a) The General Partner may propose from time to time in a written recommendation (an “Acquisition Plan”) to NYSCRF that the Partnership acquire from a third party one or more of the following: (i) land in the DC Metropolitan Area that is suitably zoned and entitled (with the exception of site plan approval and building permits) for development as an office building and which upon acquisition by the Company would be treated as a Vacant Land Property under this Agreement, (ii) land and improvements in the DC Metropolitan Area that are intended to be rehabilitated as a Redevelopment Property, or (iii) a Functional Office Property in the DC Metropolitan Area. The Acquisition Plan shall contain: (i) the maximum purchase price the General Partner would cause the Company to pay for the subject property, (ii) a description of the office market within which such property or properties are located, (iii) a summary of the existing leases (if any) of space within such property or properties, and (iv) with

- 51 -

respect only to an Acquisition Plan relating to a proposed Redevelopment Property, a preliminary capital budget for the renovation costs and a preliminary estimate of the stabilized rentals projected to be generated from such property after completion of the renovations. NYSCRF will respond with its approval or disapproval of each Acquisition Plan (or of each property that is the subject thereof, if more than one) within twenty-five (25) days after receipt of the Acquisition Plan (and NYSCRF shall have the full 25 day period to respond and elect to participate in the project even if a shorter period is indicated or identified by the Acquisition Plan). If NYSCRF fails to respond in such twenty-five (25) day period, it shall be deemed to have disapproved such Acquisition Plan. The Company shall not undertake the acquisition of any land or buildings unless the acquisition has been recommended by the General Partner and approved by NYSCRF, either pursuant to the Annual Budget process or pursuant to an Acquisition Plan. Due diligence respecting the acquisition of Vacant Land, property suitable as Redevelopment Property and Functional Office Property shall be undertaken in accordance with the procedures set forth on Exhibit K.

          (b) If the General Partner identifies land in the DC Metropolitan Area that may be suitable for development as an office building but requires rezoning or other entitlements that are not available as a matter of right as a condition to such a development and use (a “Speculative Parcel”), the General Partner (or its Affiliate) shall be free to acquire the Speculative Parcel for its own account and to pursue all appropriate rezoning, variances or other entitlements necessary for such development and use. If the General Partner subsequently determines that the necessary entitlements will not be readily obtainable or that the Speculative Parcel is not otherwise suitable or feasible for development as an office building, the General Partner (or its Affiliate) shall be free to sell the Speculative Parcel to any third party on terms acceptable to the General Partner and such third party. If the General Partner subsequently obtains the necessary entitlements for development and use of the Speculative Parcel as an office building, the General Partner (or its Affiliate) shall offer the Speculative Parcel for sale to the Company at a price equal to the fair market value of the Speculative Parcel, and the General Partner shall prepare and submit to NYSCRF an Acquisition Plan with respect thereto. The General Partner and NYSCRF shall endeavor in good faith to agree upon the fair market value of the Speculative Parcel (as approved with such entitlements), but in no event shall the fair market value of the Speculative Parcel be less than the sum of (i) the purchase price paid therefor by the General Partner, plus (ii) all carrying costs incurred with respect to the Speculative Parcel, plus (iii) all out of pocket costs incurred by the General Partner to obtain the necessary entitlements. If the parties fail to agree on the fair market value of the Speculative Parcel within sixty (60) days after the submission of the aforementioned Acquisition Plan, the parties shall endeavor in good faith to select a qualified appraiser with substantial appraisal experience in the DC Metropolitan Area commercial real estate market to determine the fair market value of the Speculative Parcel, and the determination of such appraiser shall be final. If the parties do not agree on the designation of a single appraiser, each party shall appoint a separate qualified appraiser, and the appraisers so appointed shall mutually select a third qualified appraiser with substantial appraisal experience in the DC Metropolitan Area commercial real estate market, and the determination of fair market value by such third appraiser shall be final

          (c) If NYSCRF disapproves the acquisition of the Speculative Parcel or a parcel identified as the subject of an Acquisition Plan (an “Acquisition Parcel”) by the Company, the General Partner (or its Affiliate) shall be free to acquire and develop the Speculative Parcel

- 52 -

or Acquisition Parcel for its own account substantially in accordance with the information submitted to NYSCRF in the Acquisition Plan.

     13.04 Initiation of New Developments and Redevelopments.

     14.18 Legal Representation of the Company. Wolf, Block, Schorr and Solis-Cohen LLP (“Wolf Block”) represented the General Partner in the preparation and negotiation of this Agreement, and the parties agree that such representation will not disqualify Wolf Block from representing the Company. Furthermore, if Wolf Block is engaged by the Company to represent the Company, Wolf Block will not be disqualified from thereafter representing the General Partner or its Affiliate; provided, however, that the foregoing shall not apply to waive any objection NYSCRF may have with respect to the representation by Wolf Block of (i) the General Partner or its Affiliate in litigation against the Company, or (ii) the Company in litigation against the General Partner or its Affiliate.

     14.19 Special Covenants.

5

2.2 Project Budget; Cost Overruns. Development Manager will supervise the Project to assure that the cost of the Work performed under those construction cost line items denoted on the preliminary project budget for the Project, as finally determined in the Final Project Budget for the Project, are in the aggregate equal to or less than the amounts set forth in such Final Project Budget. To the extent there are Cost Overruns (other than Cost Overruns for tenant improvements and leasing commissions), Development Manager shall promptly pay the same or, if the amount is being contested, provide adequate security therefor, including satisfying the requirements of any Construction Lender; provided, however, that Development Manager shall not be responsible for the cost of any change orders required, or Cost Overruns incurred, due to subsurface conditions at the Property of an unusual nature, unusually severe weather conditions, labor disputes (unless resulting from company-wide labor difficulties specific to Development Manager and its affiliates), unavailability of materials or labor (unless resulting from Development Manager’s lack of reasonable diligence in ordering or procuring same), war, terrorism or acts of God, other matters beyond the reasonable control of Development Manager, or otherwise initiated by Owner and not consented to by Development Manager, unless such change orders are required for the Improvements to comply with Law effective prior to the date hereof. In addition, Development Manager shall promptly pay Owner all costs incurred by Owner as a result of Development Manager’s breach of this Agreement (including but not limited to costs incurred by Owner as a result of Development Manager’s negligent acts or omissions). The Final Project Budget shall constitute a major control pursuant to which Development Manager shall manage the development and construction of the applicable Improvements. Consequently, (i) no expense may be incurred or commitment made by Development Manager which exceeds the amount allocated to that expense category in the approved Final Project Budget without Owner’s consent, provided that if the Final Project Budget, after reallocation as provided herein, remains in balance, any actual savings in any line item or amounts shown in the contingency line item may be used to offset overruns in other line items and to pay for any Permitted Changes (provided that amounts contained in the tenant improvement and leasing commissions line items may not be reallocated to pay for any such overruns), and (ii) the entire Final Project Budget shall not be exceeded without the prior consent of Owner. For purposes hereof Owner shall be deemed to approve any changes in the Final Project Budget to the extent such changes directly result from changes to Construction Contracts, if such changes to the Construction Contracts are signed by Owner. If substantial discrepancies in the Final Project Budget occur or are anticipated by Development Manager, Development Manager shall notify Owner immediately of the expected discrepancies and, if requested by Owner, prepare and submit to Owner a detailed analysis of the anticipated impact of the discrepancies. Any change to the Final Project Budget requires approval of the Owner, in Owner’s sole and absolute discretion except as provided herein, and, in the event General Partner is no longer the general partner of Owner, or if such change will result in Cost Overruns, Owner’s approval must be set forth in writing.

6

2.3 Draw Process. Development Manager shall be responsible for coordinating all construction draws, and until the opening of the applicable Construction Loan (if any), the draw process shall be controlled by the provisions of this Section 2.3. Thereafter, this Section shall be deemed modified to the extent required by the Construction Lender. Draws to finance the construction on the Improvements shall be made no more often than monthly, commencing approximately one (1) month after the commencement of construction of such Improvements and terminating upon completion of the Work and issuance of the last certificate of occupancy required by Law for full occupancy of the Improvements. Funds requested under each draw shall be used solely to pay for construction, fixturing and soft costs related to the Improvements that are consistent with the terms of this Agreement. Draw requests for the Project shall be made as follows:

2.3.1 So long as General Partner is the general partner of Owner, the following procedure shall apply:

(a) The General Contractor’s application for payment and other invoices shall be submitted to Development Manager (and to the Architect with respect to the General Contractor’s application for payment) no later than the tenth (10th) day of the month following the month in which the work which is the subject of such application for payment or invoices was completed;

(b) Development Manager shall review the General Contractor’s application for payment and all other invoices, and the Architect shall review the General Contractor’s application for payment, and to the extent such are approved by Development Manager and the Architect, Development Manager shall submit a draw request in Development Manager’s customary internal form (an “Internal Draw Request”) to Owner no later than the twenty-first (21st) day of the month following the month in which the work which is the subject of such Internal Draw Request was completed;

(c) Owner shall pay the entire amount of the Internal Draw Request for distribution no later than ten (10) business days after the Internal Draw Request is submitted to Owner.

2.3.2 Notwithstanding the foregoing provisions of Section 2.3.1, if General Partner is no longer the general partner of the Owner, then the following procedure shall apply:

(a) within ten (10) days after a draw is requested, Development Manager will submit a draw request to the Owner in such detail as Owner may reasonably require designated to the attention of Anthony Ferrante. Such draw request shall include:

(i) an Application and Certificate for Payment (AIA Document G702), or other document acceptable to the Owner, containing a certification by the General Contractor and the applicable Architect that construction to the date of the draw request is in accordance with the Final Plans and Specifications and, if applicable, any recommendations contained in the approved soils report;

(ii) a copy of the General Contractor’s application for payment, including the General Contractor’s and subcontractors’ conditional lien waivers on progress payments;

7

(iii) the General Contractor’s and subcontractors’ unconditional lien waivers for progress payments made from the previous draw;

(iv) a line by line comparison of the budgeted versus the actual costs and estimate of the percentage of completion for the Work item covered by such line item; and

(v) all other documents and information reasonably required by Owner.

(b) Owner shall review the draw request and contact Development Manager as soon as reasonably practicable in the event Owner has any questions regarding the draw request or disputes any of the items for which payment is requested. In the event Owner and Development Manager are unable to agree on the draw request within twenty (20) days after such is submitted to Owner, the matter shall be submitted to the Architect, whose decision regarding the draw request shall be binding upon Owner and Development Manager so that by the tenth (10th) day of the following month, Owner shall have approved (or, in the case of a dispute submitted to the Architect for resolution, Owner shall be deemed to have approved) the draw request and shall pay the entire approved amount of the draw for distribution to the General Contractor and subcontractors.

2.4 Employees. Development Manager shall select, employ, pay, supervise and discharge all employees, independent contractors, and personnel necessary for the performance of Development Manager’s duties pursuant to the terms hereof, all at the sole cost and expense of the Development Manager. All personnel used by Development Manager in the construction and operation of the Improvements shall be employees of Development Manager, employees of an Affiliate of Development Manager or independent contractors and not employees of the Owner. If General Partner is no longer the general partner of Owner, members of the project team down to the level of the on-site project manager shall be subject to Owner’s approval.

2.5 Payments. Development Manager shall check and verify all bills received for services, work and supplies ordered in connection with the construction on the Improvements. If such bills relate to materials supplied or work performed on the Improvements, Development Manager shall obtain all necessary lien waivers evidencing payment of such obligations.

2.6 Items to be Obtained by Development Manager. Development Manager shall obtain or cause to be obtained all licenses, permits or other instruments required for construction of the Improvements or any portion thereof at Owner’s expense. All such licenses and permits relating to construction of the Improvements shall be set forth in the Final Project Budget and shall be obtained in Owner’s name.

THIS COMPLETION GUARANTY (this “Guaranty”), made as of the     day of                     , 200   , by LIBERTY PROPERTY LIMITED PARTNERSHIP, a Pennsylvania limited partnership, with a mailing address of 500 Chesterfield Parkway, Malvern, Pennsylvania 19355 (“Guarantor”), to and for the benefit of                                         , (“Owner”), with a mailing address of 500 Chesterfield Parkway, Malvern, Pennsylvania 19355.

WITNESSETH:

WHEREAS, Owner and Guarantor entered into a Development Management Agreement dated                     , 2007 (the “Agreement”), pursuant to the terms of which Guarantor has agreed to develop Improvements on the Property. A copy of the Agreement is attached as Exhibit A hereto and made a part hereof. All capitalized terms used in this Guaranty and not otherwise defined herein shall have the meanings ascribed to such terms in the Agreement; and

WHEREAS, pursuant to the requirements of Section 2.7 of the Agreement, Guarantor is providing this Guaranty for the benefit of Owner with respect to the development of the Project.

NOW, THEREFORE FOR VALUE RECEIVED, and in consideration of the foregoing Recitals and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the parties hereto agree as follows:

AGREEMENTS

1. Completion Guaranty.

(a) Guarantor hereby unconditionally guarantees: (i) the lien-free completion of the Work (1) on the Project substantially in accordance with the Final Plans and Specifications therefor; and (2) on or before the completion date set forth in the Construction Schedule for the Project; (ii) the payment of all Cost Overruns (subject to the limitations set forth in Section 2.2 of the Agreement) and (iii) payment to Owner of all costs incurred by Owner as a result of Development Manager’s breach of the Agreement (including but not limited to costs incurred by Owner as a result of Development Manager’s negligent acts or omissions) (collectively the “Guaranteed Liabilities”). For purposes hereof, Cost Overruns shall not include costs incurred due to subsurface conditions at the Property of an unusual nature, unusually severe weather conditions, labor disputes (unless resulting from company-wide labor difficulties specific to Guarantor and its affiliates), unavailability of materials or labor (unless resulting from Guarantor’s lack of reasonable diligence in ordering or procuring same), war, terrorism or acts of God, or other matters beyond the reasonable control of Guarantor (“Force Majeure”)

26

(b) Guarantor further agrees to pay all expenses legal and/or otherwise (including but not limited to court costs and reasonable attorneys’ fees and expenses), paid or incurred by Owner in endeavoring to collect the Guaranteed Liabilities, or any part hereof, or in enforcing this Guaranty or in defending any suit based on any act of commission or omission of Owner with respect to this Guaranty or in connection with any Recovery Claim (as hereinbelow defined) (the “Enforcement Costs”). The Guaranteed Liabilities and the Enforcement Costs are collectively referred to as the “Guaranteed Obligations.”

(c) Notwithstanding Section 1(a) above, Guarantor’s obligation to perform the Guaranteed Obligations is subject to Force Majeure and is conditioned on Owner advancing or causing to be advanced on a monthly or other basis as required under the general construction contract or the Development Management Agreement: (i) all Project Costs as set forth in the Project Budget, and (ii) all increases in the Project Costs resulting from (A) change orders or other changes in the Work initiated or approved by Owner (other than change orders approved by Owner, where such change orders are intended to cure a breach by Guarantor of its obligations under the Development Management Agreement), (B) any breach by Owner of its obligations under the Development Management Agreement or general construction contract or other actions of Owner that result in increased costs of the Work or delays in completion thereof, and (C) Force Majeure; provided that so long as Liberty Washington Venture, LLC (“General Partner”) is the general partner of Liberty Washington, LP (the “Joint Venture”), the failure of General Partner to fund its share of the amounts described in clauses (i) and (ii) above (in accordance with the provisions of the Joint Venture’s partnership agreement) shall not relieve Guarantor of its obligations under this Guaranty.

2. Continuing Guaranty. This Guaranty includes any and all Guaranteed Obligations arising under successive transactions entered into between Owner and Guarantor continuing, compromising, extending, increasing, modifying, releasing, or renewing the Guaranteed Obligations or other terms and conditions thereof, or creating new or additional Guaranteed Obligations after prior Guaranteed Obligations have been satisfied in whole or in part. To the maximum extent permitted by law, Guarantor hereby waives any right to revoke this Guaranty.

3. Termination of Guaranty. In the event that the Agreement is terminated for any reason, this Guaranty shall automatically terminate contemporaneously therewith; provided, however, that Guarantor shall remain liable for any Guaranteed Liabilities which arise prior to the termination of the Agreement.

4. Primary Obligations. This Guaranty is a primary and original obligation of Guarantor, is not merely the creation of a surety relationship, and is an absolute, unconditional, and continuing guaranty of payment and performance which shall remain in full force and effect without respect to future changes in conditions, including any change of law, subject to Paragraph 1(c) above. Guarantor agrees that its liability hereunder shall be immediate and shall not be contingent upon the exercise or enforcement of any lien or realization upon any security or collateral Owner may at any time possess. Guarantor consents and agrees that Owner shall be under no obligation to marshal any assets of Guarantor or any other guarantor in favor of Guarantor, or against or in payment of any or all of the Guaranteed Obligations.

27

5. Waivers.

(a) Guarantor hereby waives: (1) notice of acceptance hereof; (2) notice of the amount of the Guaranteed Obligations, subject, however, to Guarantor’s right to make inquiry of Owner to ascertain the amount of the Guaranteed Obligations at any reasonable time; (3) notice of any fact that might increase Guarantor’s risk hereunder; (4) notice of presentment for payment, demand, protest, and notice thereof as to any promissory notes or other instruments, writing or agreements evidencing Guaranteed Obligations; and (5) all other notices (except if such notice is specifically required to be given to Guarantor hereunder) and demands to which Guarantor might otherwise be entitled.

(b) Guarantor hereby waives: (1) any rights to assert against Owner any defense (legal or equitable), setoff, counterclaim, or claim which Guarantor may now or at any time hereafter have against any party liable to Owner (other than the defense that the Guaranteed Obligations shall have been fully and finally performed and indefeasibly paid); (2) any defense, setoff, counterclaim, or claim, of any kind or nature, arising directly or indirectly from the present or future lack of enforceability of the Guaranteed Obligations; and (3) the benefit of any statute of limitations affecting Guarantor’s liability hereunder or the enforcement thereof, and any act which shall defer or delay the operation of any statute of limitations applicable to the Guaranteed Obligations shall similarly operate to defer or delay the operation of such statute of limitations applicable to Guarantor’s liability hereunder. Without limiting the generality of the foregoing or any other provisions of this Guaranty, Guarantor agrees that this Guaranty shall not be discharged, limited, impaired or affected by the operation of any present or future provision of the United States Bankruptcy Code or similar statute, or from the decision of any court, including, but not limited to, any proceedings with respect to the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all the assets, the marshalling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, imposition or readjustment of, or other similar proceeding affecting Guarantor or any guarantors of the Guaranteed Obligations or any of their respective assets, it being expressly understood and agreed that no such proceeding shall affect, modify, limit or discharge the liability or obligation of Guarantor hereunder in any manner whatsoever, and that Guarantor shall continue to remain absolutely liable under this Guaranty to the same extent, and in the same manner, as if such proceeding had not been instituted.

6. Releases. No release or discharge of any other guarantor, or of any other person or entity, whether primarily or secondarily liable for or obligated with respect to the Guaranteed Obligations, or the institution of bankruptcy, receivership, insolvency, reorganization, dissolution or liquidation proceeding by or against any other guarantor or any other person or entity, or the entry of any restraining or other order in any such proceeding, shall release or discharge Guarantor, any other guarantor of the Guaranteed Obligations, or any other person, firm or corporation liable to Owner of the Guaranteed Obligations, unless and until all of the Guaranteed Obligations shall have been fully performed and paid.

28

7. Recovery Claim. Should a claim (“Recovery Claim”) be made upon Owner at any time for recovery of any amount received by Owner in payment of the Guaranteed Obligations (whether received from Guarantor pursuant hereto, or otherwise) and should Owner repay all or part of said amount by reason of (a) any judgment, decree, or order of any court or administrative body having jurisdiction over Owner or any of its property; or (b) any reasonable settlement or compromise of any such Recovery Claim effected by Owner with the claimant, Guarantor shall remain liable to Owner of the amount so repaid to the same extent as if such amount had never originally been received by Owner, notwithstanding any termination hereof or the return of this document to Guarantor.

8. Omitted.

9. Payments; Application. All payments to be made hereunder by Guarantor shall be made in lawful money of the United States of America at the time of payment, shall be made in immediately available funds, and shall be made without deduction (whether for taxes or otherwise) of offset. All payments made by Guarantor hereunder shall be applied as follows; first, to all cost and expenses (including, but not limited to, reasonable attorney’s fees, expenses and court costs) incurred by Owner in enforcing this Guaranty or in collecting the Guaranteed Obligations; second, to all accrued and unpaid interest and fees owing to Owner constituting Guaranteed Obligations, if any; and third, to the balance of the Guaranteed Obligations.

10. Notices. Any notice or other communication required or permitted to be given shall be in writing addressed to the respective party as set forth above, and shall be deemed to be delivered (a) upon receipt, if delivered by facsimile, (b) upon receipt if hand delivered, (c) on the first business day after having been delivered to a national overnight air courier service, or (d) three business days after deposit in registered or certified mail, return receipt requested. Except as otherwise specifically required herein, notice of the exercise of any right or option granted to Owner by this Guaranty is not required to be given.

11. Cumulative Remedies. No remedy under this Guaranty is intended to be exclusive of any other remedy, but each and every remedy shall be cumulative and in addition to any and every remedy given hereunder and those provide by law or in equity. No delay or omission by Owner to exercise any right under this Guaranty shall impair any such right nor be construed to be a waiver thereof. No failure on the part of Owner to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right.

12. Interpretation and Severability of Provisions. The headings of sections and paragraphs in this Guaranty are for convenience of reference only and shall not be construed in any way to limit or define the content, scope or intent of the provisions hereof. As used in this Guaranty, the singular shall include the plural, and masculine, feminine and neuter pronouns shall be fully interchangeable, where the context so requires. Whenever the words “including”, “including” or “includes” are used in this Guaranty, they should be interpreted in a non-exclusive manner as though the words, “without limitation”, immediately following the same. Wherever possible, each provision of this Guaranty shall be interpreted in such manner as to be effective and valid under applicable law. If any provision of this Guaranty is prohibited or unenforceable under applicable law, such provision shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof.

13. Entire Agreement; Amendments. This Guaranty constitutes the entire agreement between Guarantor and Owner pertaining to the subject matter contained herein, and may not be altered, amended, or modified, nor may any provision hereof be waived or noncompliance therewith consented to, except by means of a writing executed by Guarantor as to which such consent or waiver is applicable and by Owner. Any such alteration, amendment, modification, waiver, or consent shall be effective only to the extent specified therein and for the specific purpose of which it is given. No course of dealing and no delay or waiver of any right or default under this Guaranty shall be deemed a waiver of any other similar or dissimilar right or default or otherwise prejudice the right and remedies hereunder.

14. Successors and Assigns. This Guaranty shall be binding upon Guarantor’s representatives, successors, and assigns and shall inure to the benefit of the successors and assigns of Owner.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT IT MAY HAVE TO ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION.

30

4.4 Advances and Reimbursements.

ARTICLE X

Assignment

This Agreement may not be assigned by Manager nor shall Manager delegate any of its duties hereunder without Owner’s prior written consent except to an Affiliate of Manager (which assignment shall not relieve Manager of its liability hereunder). The engagement by Manager of attorneys, accountants, engineers, contractors and other professionals shall not be deemed to be a delegation of Manager’s duties hereunder. Any purported assignment without such consent shall be void and of no effect. In the event Owner sells the Property and seeks to assign this Agreement to the purchaser, Manager shall have the option to terminate this Agreement as of the date of such purchase.

ARTICLE XI

Relationship of Parties

11.1 Nature of Relationship. In taking any action pursuant to this Agreement, Manager will be acting only as independent contractor, and not as an agent, with limited authority to act in Owner’s name only in accordance with the terms of this Agreement and nothing explicit or implied in this Agreement shall be construed as creating a partnership, joint venture, employment or agency relationship between Manager (or any person employed by Manager) and Owner or any other relationship between the parties hereto and Owner and Manager each hereby expressly disavow any agency or other relationship between Owner and Manager except that of Owner and independent contractor. Manager acknowledges and agrees that it shall act as an independent contractor hereunder with respect to Owner in connection with Manager’s obligations under this Agreement. Without limiting the generality of the foregoing, the parties acknowledge that Manager holds a direct or indirect partnership interest in Liberty Washington, LP, the direct or indirect owner of Owner, and agree that if, for any reason, Manager is deemed to be an agent of Owner, such agency shall be deemed coupled with an interest in Owner (consisting only of the interest in Liberty Washington, LP then held by the Affiliate of Manager) and irrevocable.

10

11.2 Communications Between Parties. Owner relies on Manager to direct and control all operations at the Property; provided, however, Owner reserves the right to communicate directly with the on-site building manager, Manager’s accountant or accountants working on Property matters and other employees with respect to financial matters, all tenants and tenants’ representatives, all lease prospects, all advertising, management, cleaning and servicing firms doing work for the Property, and all parties contracting with Owner or Manager with respect to the Property.

11.3 Confidentiality. Manager shall maintain the confidentiality of all matters pertaining to this Agreement and all financial operations and transactions relating to the Property, except as may be required by law; provided, however, that Manager shall not be in breach of its obligations under this Agreement or any other obligations or duties to Owner, or its partners, at law or in equity (whether under a theory of fiduciary duty or otherwise) if Manager or its Affiliates files this Agreement (and some or all of the exhibits hereto) as an exhibit to a filing it may make with the Securities Exchange Commission or makes disclosures regarding the transactions governed by this Agreement to the extent the Manager or its Affiliates reasonably believe necessary to enable the Manager or its Affiliates to comply with federal and state securities laws and the regulations of the Securities Exchange Commission, the rules of any stock exchange, or in connection with any filing or registration made by Liberty Property Trust, an Affiliate of Manager, as the issuer of publicly traded securities, or as part of information provided to its investors and/or financial analysts.

ARTICLE XII

Defaults and Termination

12.1 Default by Manager. Manager shall be deemed to be in default hereunder in the event: (i) Manager shall fail to keep, observe or perform any material covenant, agreement, term or provision of this Agreement to be kept, observed or performed by Manager and such default shall continue for a period of thirty (30) days after written notice thereof by Owner to Manager; provided, however, that if such failure is not susceptible of cure within such thirty (30) day period and Manager has commenced and is diligently attempting to cure such failure, then Manager shall have an additional sixty (60) days in which to cure such failure; or (ii) a receiver is appointed to take possession of the assets of Manager or an assignment by Manager for the benefit of creditors, or any action taken or suffered by Manager under any insolvency, bankruptcy, reorganization, moratorium, or other debtor-relief act or statute. Upon the occurrence of an event of default by Manager, Owner shall be entitled to seek specific performance of this Agreement, but in no event shall Owner be entitled to terminate this Agreement except as set forth in Section 12.2 below.

12.2 Ownership Interests in Owner. In the event that Liberty Property Limited Partnership or its permitted assignee hereunder, or an Affiliate of such parties, no longer has a direct or indirect ownership interest in Owner, then either Owner or Manager shall be entitled to terminate this Agreement upon written notice to the other.

11

12.3 Orderly Transition. In the event of any termination of this Agreement, Manager shall use its commercially reasonable efforts to effect an orderly transition of the management and operation of the Property to Owner or an agent designated by Owner and to cooperate with Owner, at Owner’s expense, or such agent.

12.4 Final Settlement of Accounts. Upon the termination of this Agreement, Manager promptly shall:

(a) account for and deliver to Owner all receipts, charges and income from the Property and other monies of Owner in Manager’s possession;

(b) deliver to Owner as received any monies due Owner under this Agreement but received after such termination;

(c) deliver to Owner or to such other person as Owner shall designate, all materials, supplies, equipment, keys, original leases, contracts, documents, books and records pertaining to this Agreement and the Property;

(d) assign without warranty or recourse existing contracts and permits in the name of Manager relating to the Property to Owner or to such party as Owner shall designate; and

(e) within 30 days after the effective date of termination of this Agreement, cause to be furnished to Owner a summary of the then-current leasing status of the Property.

12.5 Default by Owner. In the event Owner fails to pay any commission or Management Compensation due to Manager hereunder (except where such failure is the result of a failure by Liberty Washington Venture, LLC, the general partner of Owner [the “General Partner"], to provide funds to Owner in accordance with Owner’s Agreement of Limited Partnership of even date herewith, as amended from time to time the [“Partnership Agreement"], Manager shall have all of its remedies available at law or in equity. Additionally, if Owner fails to provide funds necessary for Manager to carry out its duties hereunder (except for the reasons stated in the parenthetical to the foregoing sentence), Manager may advance such funds for the account of Owner and Owner shall promptly thereafter reimburse such funds to Manager together with interest thereon at the Default Rate. In no event shall Manager be entitled to terminate this Agreement except in accordance with Section 12.2 above.

ARTICLE XIII

Legal Proceedings

13.1 Cooperation by Manager and Owner. Manager and Owner shall fully cooperate, and shall cause their respective employees to fully cooperate, at Owner’s expense, in connection with the prosecution or defense of all legal proceedings affecting the Property; provided, that in the event a court of applicable jurisdiction rules that Manager or its officers, partners, directors, shareholders, trustees, beneficial owners, agents or employees has engaged in gross negligence or willful misconduct with respect to the subject of such proceedings, Manager shall reimburse Owner for its reasonable attorney fees and costs incurred in prosecuting such proceedings.

12

ARTICLE XIV

Miscellaneous

14.1 Governing Law. This Agreement shall be construed and enforceable in accordance with the laws of the state where the Property is located.

14.3 Successors and Assigns. All terms, conditions and agreements herein set forth shall inure to the benefit of, and be binding upon the parties and their respective permitted successors and assigns.

14.4 Waiver. The failure of either party to insist upon strict performance of any term or provision of this Agreement or to exercise any option, right or remedy herein contained, shall not be construed as a waiver or as a relinquishment for the future of such term, provision, option, right or remedy, but the same shall continue and remain in full force and effect. No waiver by either party of any term or provision hereof shall be deemed to have been made unless expressed in writing and signed by such party.

14.5 Partial Invalidity. If any portion of this Agreement shall be decreed invalid by the judgment of a court, this Agreement shall be construed as if such portion had not been inserted herein except when such construction would constitute a substantial deviation from the general intent and purpose of this Agreement.

14.6 ERISA and Unrelated Business Taxable Income. Manager agrees to use commercially reasonable efforts to act in accordance with the fiduciary standards of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) to the extent Manager is subject thereto as a result of services rendered pursuant to this Agreement. Manager shall use its commercially reasonable efforts to avoid taking any action that would subject Owner to the tax on unrelated business taxable income under the Internal Revenue Code, as it exists at the time such action is taken (the “Code”). Manager shall abide by any and all procedures established by Owner to avoid prohibited transactions under ERISA and unrelated business taxable income under the Code.

14.7 Limitation on Owner’s Liability. The obligations of Owner are intended to be binding only on the Property and shall not be personally binding upon, nor shall any resort be had to, the private properties of its trustees, beneficiaries, advisers, officers, directors, or shareholders, as applicable, or its investment manager, or the general partners, officers, directors, or shareholders thereof, as applicable, or any employees or agents of any of them.

14.8 Waiver of Liens.

13

14.9 Affiliates. As used herein, the term Affiliate shall mean a party controlling, controlled by or under common control with the party in question.

14.10 Limitation on Manager’s Liability. The obligations of Manager are intended to be binding only on the assets of the Manager and shall not be personally binding upon, nor shall any resort be had to, the private properties of its shareholders, trustees, beneficiaries, directors, officers, employees or agents, provided, however, the Owner shall retain the right, after notice to the Manager, to offset any amounts claimed against Manager hereunder against amounts due General Partner under the Partnership Agreement, and further provided that if there is any dispute as to whether the claim against Manager is valid, the amount sought to be withheld shall be escrowed until the first to occur of the matter being resolved or Manager, after written notice from Owner, no longer contesting the validity of the claim, with the interest earned thereon being paid to the party who is ultimately determined to be entitled to the amount claimed or, if it is determined that each party is entitled to a portion of the amount in dispute, pro rata based on the amount paid to each.

Recitals

A. On the day prior to the Effective Date, NYSCRF contributed the sum of $415,063,748.00 to the Company.

B. On the Effective Date, the following transactions occurred in the following order:

(i) First, prior to completion of the Merger, the Company entered into one or more agreements with RPLP whereby RPLP agreed to sell, and the Company agreed to purchase, 100% of the ownership interests (the “Purchased Interests”) in Republic 20th Street, LLC, a Delaware limited liability company, RPLP I, LLC, a Delaware limited liability company, and RPT 1425 Investors, LP, a Delaware limited partnership (collectively, the “Purchased Entities”), for an aggregate amount equal to $76,540,000.00 (the “Purchase Price”).

(ii) Second, prior to completion of the Merger, the Company closed on the purchase of the Purchased Interests. The consideration for such purchase was a purchase money promissory note from the Company to RPLP in the full amount of the Purchase Price. The promissory note described in this Recital B(ii) is referred to herein as the “Purchase Money Note”. The Purchase Money Note was nonrecourse to the Company and was secured by a pledge by the Company of its ownership interests in Republic 20th Street LLC and Liberty Property Philadelphia Limited Partnership. The Purchase Money Note, together with the documents securing the Purchase Money Note, are referred to herein collectively as the “Purchase Money Loan Documents”. Immediately upon issuance of the Purchase Money Note, RPLP conveyed the Purchased Interests to the Company.

(iii) Third, prior to completion of the Merger, the General Partner made a loan to RPLP in the aggregate amount of $59,500,000.00 (the “Liberty Loan”). The Liberty Loan was nonrecourse to RPLP, secured by a pledge by RPLP to the General Partner of all of RPLP’s interests in RKB Lakeside LLC, a Delaware limited liability company (“Lakeside, LLC”), and RKB WillowWood LLC, a Delaware limited liability company (“WillowWood, LLC”), and evidenced by a promissory note and a loan and security agreement (the “Liberty Loan Documents”). Prior to completion of the Merger, RPLP applied the proceeds of the Liberty Loan to defease the existing mortgage loans that encumber the assets owned by Lakeside, LLC and WillowWood, LLC.

(iv) Fourth, prior to completion of the Merger, the Company made a loan to LPLP in an amount equal to $415,063,748.00 (the “Merger Loan”), which was fully recourse to LPLP and evidenced by a promissory note from LPLP to the Company. LPLP used the proceeds of the Merger Loan to complete the Merger.

(v) Fifth, immediately after completion of the Merger, LPLP contributed the Contributed Interests and its interests in and to the Purchase Money Loan Documents to the Company on behalf of the General Partner, subject to the Liberty Loan, in satisfaction of the Merger Loan, to the extent thereof, and the balance as a contribution to the capital of the Company. Contemporaneously with the contribution of the Contributed Interests to the Company, LPLP assigned, and the Company assumed, all of LPLP’s interests and obligations as borrower under the Liberty Loan Documents, including the obligation to make payments under the note evidencing the Liberty Loan.

Report of Independent Accountants

To the partners of Liberty Washington, LP

In planning and performing our audit of the consolidated financial statements of Liberty Washington, LP for the year ended December 31, 200_____, we considered its internal control to determine our auditing procedures for the purpose of expressing our opinion on the consolidated financial statements and not to provide assurance on internal control. Our consideration of internal control would not necessarily disclose all matters in internal control that might be material weaknesses under standards established by the American Institute of Certified Public Accountants. A material weakness is a condition in which the design or operation of one or more of the internal control components does not reduce to a relatively low level the risk that misstatements caused by errors or fraud in amounts that would be material in relation to the consolidated financial statements being audited may occur and not be detected within a timely period by employees in the normal course of performing their assigned functions. However, we noted no matters involving internal control and its operation that we consider to be material weaknesses as defined above.

This report is intended solely for the information and use of the partners of Liberty Washington, LP, management, and others within the organization and is not intended to be and should not be used by anyone other than these specified parties.

We would be pleased to discuss the above matters or to respond to any questions, at your convenience.

EXHIBIT K

DUE DILIGENCE AND CLOSING PROCEDURES FOR ACQUISITION OF VACANT
LAND, LAND AND IMPROVEMENTS SUITABLE FOR BEING REHABILITATED AS
REDEVELOPMENT PROPERTY, AND FUNCTIONAL OFFICE PROPERTY

1. Third Party Costs. Upon approval of an Acquisition Plan by NYSCRF, all costs and expenses of Approved Vendors incurred in connection with the proposed acquisition and any refundable earnest money deposits to be applied against the purchase price (“Third Party Costs”) shall be the sole responsibility of the Company. Notwithstanding the above, such Third Party Costs may be incurred by the Company prior to receipt of NYSCRF’s approval and paid for out of an “Acquisition Reserve Account” having a total balance in the amount of $100,000 that will be funded by General Partner and NYSCRF in accordance with their respective partnership interests upon the formation of the Company and, to the extent necessary to maintain a balance in the amount of $100,000, at the beginning of each year following such formation. If NYSCRF subsequently approves the Acquisition Plan, then the amount of funds incurred for Third Party costs pursuant to this Section shall not be charged against the Acquisition Reserve Account. If NYSCRF subsequently disapproves the Acquisition Plan, then the amount of funds incurred for Third Party costs pursuant to this Section shall be charged against and reduce dollar for dollar the Acquisition Reserve Account. If the funds in the Acquisition Reserve Account are exhausted or are insufficient to pay required Third Party Costs, such costs shall not be incurred by the Company until NYSCRF has given its written approval of an Acquisition Plan for the remainder of that year or until the Partners mutually agree to replenish the Acquisition Reserve Account. Notwithstanding the foregoing, if the General Partner requires funds in excess of the Acquisition Reserve Account to place a refundable earnest money deposit prior to NYSCRF’s approval of the corresponding Acquisition Plan, the General Partner may provide NYSCRF with a signed letter of intent for such transaction, which NYSCRF shall approve or disapprove within six (6) business days thereafter. If the letter of intent is approved by NYSCRF, the Partners shall each promptly contribute funds to the Company in accordance with their respective partnership interests sufficient to fund the refundable deposit contemplated under the letter of intent.

2. Due Diligence Review. Acquisitions shall be subject to normal and customary due diligence review to be performed by an Approved Vendor, including, without limitation, an environmental assessment (using the criteria for a phase I environmental assessment described on Schedule 1 to this Exhibit), physical inspection report, title review (using a nationally recognized title insurance company) and survey review (of a survey prepared in accordance with ALTA/ASCM requirements customarily obtained and sufficient to enable the title company to issue an ALTA policy of title insurance without a survey exception at closing). General Partner shall use commercially reasonable efforts to cause all due diligence investigations to be completed and reports in connection therewith delivered concurrently to NYSCRF and Advisor at least five (5) business days prior to the end of the due diligence period stated in the purchase contract (the “Due Diligence Period”); NYSCRF shall have no obligation to approve or disapprove any acquisition until six (6) days after it has received such materials, but General Partner may terminate the purchase contract (after making reasonable efforts to extend the Due Diligence Period) if NYSCRF’s approval is not obtained prior to the end of the Due Diligence Period. General Partner shall furnish to the Advisor copies of due diligence materials and reports, including the environmental assessment, physical inspection report, title and survey documents, final pro forma and financial projections as they are completed. The Advisor, upon completion of its review, will submit a report to NYSCRF summarizing its conclusions with respect to completed due diligence and identifying any conditions that would warrant withdrawal of NYSCRF’s approval of the Acquisition Plan.

3. [The confidential information contained herein has been omitted and separately filed with the staff.]

4. Capital Call Notice. Provided that the proposed acquisition has not been earlier terminated, after the expiration of the Due Diligence Period, General Partner shall submit a written request (a “Capital Call Notice”) to the Advisor setting forth the acquisition price, closing costs and any other costs to complete the acquisition and NYSCRF’s share of such costs. The Capital Call Notice will identify wiring instructions including the due date for receipt of NYSCRF’s share of such costs which shall not be less than six (6) business days after the receipt of the Capital Call Notice by Advisor. Such due date shall also not be more than one (1) day prior to the closing of the property acquisition by the Company.

5. Closing: Comfort Letter, Insurance, Closing Statement and Closing Book. At least five (5) business days prior to closing, General Partner shall cause counsel to the Company to deliver to the Company a “comfort letter” (i) describing the transaction documentation respecting the property acquisition that such counsel has either prepared, reviewed or negotiated on behalf of the Company and confirming that such documentation complies with the Acquisition Plan, or, to the extent of any variance therefrom, specifying such exceptions, (ii) describing the legal matters that such counsel has reviewed and considered in connection with the property acquisition (including, without limitation (to the extent applicable) the purchase and sale agreement, closing documentation, title, survey, recorded documents disclosed by title, and loan documents) and specifying any significant and adverse legal issues in connection therewith that remain unresolved, and (iii) addressing such other matters as may be reasonably requested by either Partner. If the Company is represented by more than one legal counsel in connection with the acquisition, multiple comfort letters from such counsel may be obtained to satisfy the foregoing requirements. On or before closing, General Partner shall cause a certificate of insurance to be issued to the Company in connection with the property. Within one (1) business day after closing, General Partner shall deliver to Advisor an executed closing statement. Within thirty (30) days after the Closing Date, General Partner shall deliver to Advisor a “closing book” containing all fully executed documents related to the acquisition and acknowledging the receipt and copies of all certificates and documents (including certificates of insurance) delivered or required in connection with the closing of the acquisition of the property.

DUE DILIGENCE AND CLOSING PROCEDURES FOR NEW DEVELOPMENT AND
REDEVELOPMENT PROPERTY

2. NYSCRF Consultant. Upon receipt of the NYSCRF’s approval of a Development Plan, NYSCRF may, at is sole cost and expense, appoint an inspecting engineer, contractor and/or architect to serve as its consultant with respect to the design, development and construction of the New Development or Redevelopment (collectively, the “NYSCRF Consultant”).

Notwithstanding the foregoing, in the event any construction lender for the New Development or Redevelopment requires the engagement of one or more consultants with a similar function to the NYSCRF Consultant, NYSCRF may elect to rely on such lender’s consultants rather than engage a separate NYSCRF Consultant, and the cost thereof shall be a Company expense. General Partner shall reasonably cooperate (and shall cause the Developer under the Development Management Agreement to reasonably cooperate) with the NYSCRF Consultant and shall provide the NYSCRF Consultant with reasonable access to all plans, specifications, drawing, budgets, reports and other documents, information and materials relevant to the NYSCRF Consultant’s monitoring and evaluation of the progress and implementation of the design, development and construction of the NEW Development or Redevelopment.

The Capital Call Notice will identify wiring instructions including the due date for receipt of the initial Development Property Capital Contribution, which shall be not be less than ten (10) business days after the date of receipt of the Capital Call Notice by the Advisor and NYSCRF.

5. Additional Capital Contributions. As an alternative or supplement to the procedure set forth in Paragraph 4 above, upon the mutual agreement of the Partners, the Partners may proceed as follows: General Partner shall prepare regular Capital Call Notices for additional Development Property Capital Contributions to be made by the Partners with respect to the Approved Development in accordance with the Final Project Budget. The Capital Call Notices shall contain (i) a draw request, supported by reasonable backup documentation, and containing such additional information as may be reasonably required by NYSCRF or Advisor; (ii) a certification by Liberty representing and warranting that the contents of the draw request are true and correct, and (iii) contribution date and funding instructions. The Capital Call Notices shall be delivered concurrently to the Advisor. The Advisor, upon completion of its review, will submit a recommendation to NYSCRF for funding of the Call for Capital. The partners shall complete the funding contained in the Capital Call Notice on the tenth (10^th) business day after receipt of the Capital Call Notice. Capital Call Notices shall not be issued more frequently than once per calendar month. General Partner shall endeavor to deliver the Capital Call Notice to Advisor in sufficient time to allow for the Company to pay accrued construction costs by the end of each calendar month, as contemplated in the Development Management Agreement. If General Partner fails to deliver the Capital Call Notice to Advisor within the time period specified in the immediately preceding sentence, General Partner shall be solely responsible for any consequential damages arising by reason of such failure.

               (ii) Litigation. There is no pending nor, to Liberty’s knowledge, threatened litigation or administrative proceedings that, if resolved adversely to Liberty or any Entity would adversely affect title to the Property or any part thereof or the ability of Liberty to perform any of its obligations hereunder or the use of the Property by the Company as it is presently being used or otherwise materially and adversely affect the Property, except as set forth on Schedule 4.1(b)(ii) (the “Existing Litigation”).

               (iii) Notice of Liens. Liberty has not received written notice of the intention of any governmental authority to file or impose any liens (other than statutory liens for real estate taxes not yet due and payable) or special assessments against any of the Property, nor, to Liberty’s knowledge, do there currently exist any facts or circumstances that would allow any governmental authority the right to file or impose such liens or assessments.

               (iv) Schedule of Leases; Rent Roll; Tenant Leases. To Liberty’s knowledge, the Schedule of Lease Documents (the “Schedule of Leases”) provided to NYSCRF pursuant to Section 3.1 hereof is a complete and correct list of all Tenant Leases and amendments thereto in effect as of the date of this Agreement.

5

               (v) Encumbrances on Tenant Leases. To Liberty’s knowledge, subject to the Assumed Financing, none of the Tenant Leases and none of the rents or other amounts payable thereunder has been assigned, pledged or encumbered by Liberty, except for any assignment, pledge or encumbrance that Liberty will cause to be terminated or released at or prior to Closing.

               (vi) Brokerage or Leasing Commissions. Except as disclosed on the Rent Roll, to Liberty’s knowledge, no brokerage or leasing commissions or other compensations are due or payable by Liberty to any person, firm, corporation, partnership, limited liability company or other entity (each a “Person”) with respect to or on account of the current term of any of the Tenant Leases. Except as disclosed in the Rent Roll or set forth in the Tenant Leases, to Liberty’s knowledge, no brokerage or leasing commissions or other compensations are due or payable by the landlord on any extension or expansion of any Tenant Lease.

               (vii) Obligations to Tenants under Tenant Leases. Except as set forth on Schedule 4.1(b)(vii) attached hereto, with respect to tenants in occupancy under Tenant Leases as of the Closing Date, to Liberty’s knowledge, there are no unperformed obligations to provide any tenant under any Tenant Lease with any painting, repair, alteration, carpeting, appliance or any other equipment or work of any kind, under any Tenant Lease or under any other oral or written agreement whatsoever that would excuse such tenant from accepting its Premises under the terms of its lease, except for obligations (i) that will be performed and paid for by Liberty before the Closing or (ii) to complete any portion of the Premises covered by the Tenant Lease not yet occupied by the tenant thereunder and not required to be completed under the terms of the Tenant Lease as of the Closing Date or pursuant to renewal rights under Tenant Leases.

               (viii) Enforceability of Tenant Leases. To Liberty’s knowledge, each of the Tenant Leases is valid and subsisting and in full force and effect in accordance with its terms, provisions and conditions and constitutes the legal, valid, binding and enforceable obligation of the tenant thereunder, subject to laws applicable generally to creditor’s rights. As of the date of this Agreement, neither Liberty nor, to the knowledge of Liberty, the tenant is in material default thereunder. To Liberty’s knowledge, as of the date of this Agreement, (i) each tenant under a Tenant Lease scheduled to be in possession as of the date hereof has accepted the premises covered by its Tenant Lease and is in possession of such premises in accordance with its Tenant Lease, and (ii) all initial installation work, if any, required of Liberty in order for the tenant to accept the premises then in actual occupancy by a tenant under the terms of its lease has been fully performed, paid for and accepted by each such tenant. To Liberty’s knowledge, no tenant under a Tenant Lease that has been signed as of the date hereof has any pending litigation, offsets or counterclaims against Liberty that, if successfully asserted, would reduce the rent payable thereunder or result in the cancellation or termination thereof. No tenant has given any written notice to Liberty of such tenant’s intention of instituting litigation with respect to any Tenant Lease or terminating its tenancy. Each of the representations and warranties set forth in this Section 4.1(viii) is subject to the matters disclosed on Schedule 4.1(viii) attached hereto.

into any agreement with any Person granting the right to possess the Property, other than (i) tenants in possession pursuant to the Tenant Leases described in the Schedule of Leases, (ii) tenants under Tenant Leases entered into by the Entities after the date hereof in accordance with Section 3.3; or (iii) matters of public record.

With respect to the Property, neither Liberty nor, to Liberty’s knowledge, any Entity has received any written notice from any insurance company, governmental agency or any other Person of (i) any condition, defect, or inadequacy affecting the Property that, if not corrected, would result in termination of insurance coverage or materially increase its cost, (ii) any pending or threatened condemnation proceedings, or (iii) any proceedings that could or would reasonably be likely to cause the change or other material modification of the zoning classification or other legal requirements, applicable to the Property or any part thereof which would materially and adversely affect the Property. To Liberty’s knowledge, there does not exist any court order, nor does there exist any restriction or restrictive covenant (save and except matters of public record and all laws, statutes, ordinances and regulations of applicable governmental authorities) or other private or public limitation, that is reasonably likely to materially and adversely affect the use of the Property as presently being operated.

               (xiii) Streets and Highways. Neither Liberty nor, to Liberty’s knowledge, any Entity has received a written notice of any existing plans to widen, modify or realign any street adjoining the Property.

               (xiv) Unfulfilled Binding Commitments. No commitments have been made by Liberty nor, to Liberty’s knowledge, any Entity to any Governmental Authority, utility company, school board, church or other religious body, or any homeowners or homeowners’ association, or any other organization, group or individual, relating to the Property (other than with respect to any declaration in place at the Property) that would impose an obligation upon the Company or its successors or assigns to make any contribution or dedications of money or land or to construct, install or maintain any improvements of a public or private nature on or off the Property, except for obligations due under the Tenant Leases and all recorded instruments.

7

               (xv) Service Contracts, Tenant Leases, etc. To Liberty’s knowledge, there are no other contracts (including collective bargaining agreements), other than the Service Contracts, the Tenant Leases and matters of public record, that materially and adversely affect the Property or the operation thereof except as provided to NYSCRF pursuant to Section 3.1.

          (d) In the event of any post-Closing increase or decrease in the amount of transfer tax payable hereunder, the parties hereto shall pay or be reimbursed for such increase or decrease, as the case may be, in accordance with, and in proportion to, each party’s obligation as set forth in this Section 6.4. This Section 6.4(d) shall survive Closing.

     7. PRORATIONS

     7.1 Initial Proration. Within [The confidential material contained herein has been omitted and has been separately filed with the Commission.] days after the Closing Date, the parties shall prorate the following items as of the Closing Date:

          (a) Taxes. All real estate taxes with respect to the Property shall be prorated between Liberty and the Company as of the Closing Date.

          (b) Rents. Rent shall be prorated as of the Closing Date, except that no proration shall be made for rents delinquent as of the Closing Date (hereinafter called the “Delinquent Rents”). The Company shall have no liability to Liberty for the Delinquent Rents and shall have no obligation to collect same, provided, however, amounts collected by the Company or the Entities from tenants owing Delinquent Rents shall be applied first to rents owed by such tenant accruing from and after the Closing Date and then to Delinquent Rents. Any such amounts applicable to Delinquent Rents received by the Company or the Entities shall be forwarded to Liberty within fifteen (15) days of receipt thereof. Liberty reserves the right to pursue legal remedies against tenants owing Delinquent Rents so long as pursuit of its legal remedies does not cause the tenant to be evicted.

          (c) Operating Costs. All operating expenses, including utilities (to the extent not paid directly by tenants), maintenance and other operating costs and expenses incurred by the Entities in connection with the ownership, operation, maintenance and management of the Property shall be prorated between Liberty and the Company as of the Closing.

          (d) Insurance Premiums. Insurance premiums shall be prorated as of the Closing Date.

          (e) Other Income and Expenses. All other income from, and expenses of, the Property, including but not limited to public utility charges, maintenance charges and service

16

charges, shall be prorated as of the Closing Date and the Company shall assume such expenses for periods subsequent to Closing.

          (f) Federal, State and Local Taxes. To the maximum extent permissible, for Federal, State and local tax purposes the parties will cause the Entities and their subsidiaries to treat the Closing Date as the beginning of a fiscal period. Liberty will file all returns and pay all taxes owing for periods through the day preceding the Closing Date and the Company will file all returns and pay all taxes owing for periods beginning with the Closing Date. If and to the extent that such filing of separate returns is not permitted by any taxing authority, and as to any tax that applies to a period both before and after the Closing Date, the parties will cooperate in the furnishing of information necessary to the preparation and filing of returns, and will pay their respective shares of tax liability in proportion to their respective shares of the thing taxed (for example, gross receipts or net income). The obligations of the parties hereunder shall survive Closing until each such tax return has been filed, all such taxes owing have been paid and such returns and payments are no longer subject to contest by the taxing authority.

     11. TERMINATION AND REMEDIES

     11.1 Liberty’s Default.

          (a) Subject to the provisions of Section 11.1(b) below, if Liberty has not terminated this Agreement pursuant to any of the provisions hereof authorizing such termination, and if prior to or at the Closing Liberty defaults hereunder or shall have failed to have performed any of the material covenants and/or agreements contained herein that are to be performed by Liberty at or prior to the Closing, or if any warranty or representation made by Liberty herein is not true and correct in all material respects, NYSCRF may, at its option, as its sole and exclusive remedies, either (i) seek specific performance of this Agreement, or (ii) terminate this Agreement.

          (b) Notwithstanding anything in Section 11.1(a) to the contrary, NYSCRF will, prior to the exercise of the remedies contained in Section 11.1(a), give Liberty written notice (“NYSCRF’s Default Notice”) specifying the nature of such default. Until the date that is five (5) days after receipt of NYSCRF’s Default Notice, Liberty may, at its option, elect to cure such default or waive the option to cure the default; provided, however, Liberty’s failure to give NYSCRF written notice of its election within this time period shall be deemed an election by Liberty to waive its right to cure the default. If Liberty waives or is deemed to have waived its right to cure the default, NYSCRF shall thereafter be entitled to exercise the remedies in accordance with the terms of Section 11.1(a). If Liberty elects to cure the default specified in NYSCRF’s Default Notice, Liberty shall commence to cure such default within fifteen (15) days from the date of such election and diligently pursue such cure to completion within forty-five (45) days (“Liberty’s Cure Period”). If Liberty fails to cure such default within Liberty’s Cure Period to NYSCRF’s reasonable satisfaction, NYSCRF may exercise its remedies in accordance with the terms of Section 11.1(a) hereof.

     11.2 NYSCRF’s Default.

          (a) If NYSCRF has not terminated this Agreement pursuant to any of the provisions hereof authorizing such termination and NYSCRF defaults hereunder and fails to perform any of the covenants and/or agreements contained herein which are to be performed by NYSCRF, Liberty shall be entitled to, at its option, as its sole and exclusive remedies either (i) seek specific performance of this Agreement, or (ii) terminate this Agreement.

          (b) Notwithstanding anything in Section 11.2(a) to the contrary, Liberty will, prior to the exercise of the remedies contained in Section 11.2(a), give NYSCRF written notice (“Liberty’s Default Notice”) specifying the nature of such default. Until the date that is five (5)

19

days after receipt of Liberty’s Default Notice, NYSCRF may, at its option, elect to cure such default or waive the option to cure the default; provided, however, NYSCRF’s failure to give Liberty written notice of its election within this time period shall be deemed an election by NYSCRF to waive its right to cure the default. If NYSCRF waives or is deemed to have waived its right to cure the default, Liberty shall thereafter be entitled to exercise the remedies in accordance with the terms of Section 11.2(a). If NYSCRF elects to cure the default specified in Liberty’s Default Notice, NYSCRF shall commence to cure such default within fifteen (15) days from the date of such election and shall thereafter diligently pursue such cure to completion within forty-five (45) days (“NYSCRF’s Cure Period”). If NYSCRF is unable to cure such default within NYSCRF’s Cure Period to Liberty’s reasonable satisfaction, Liberty may exercise its remedies in accordance with the terms of Section 11.2(a) hereof.

     11.3 Costs and Expenses; Limitation. In the event of any default or alleged default by either Liberty or NYSCRF hereunder that results in a party seeking to exercise its rights or remedies pursuant to Section 11.1 or Section 11.2 above, the prevailing party under this Agreement shall be able to recover from the non-prevailing party on demand all actual, reasonable and necessary out-of-pocket expenses actually paid or incurred by the prevailing party in connection with the exercise of its remedies hereunder including, without limitation, reasonable attorneys’ fees. In no event shall either party hereto, or any direct or indirect partner, member, shareholder, beneficiary, owner or affiliate thereof, or any officer, director, employee, trustee, or agent of any of the foregoing or any affiliate or controlling person thereof, be liable to any indemnified party in contract, tort or otherwise with respect to any indirect, consequential, punitive or exemplary damages arising from or relating to this Agreement or any closing document.

     11.4 Limitation of NYSCRF Liability. Notwithstanding anything to the contrary contained herein or in any other agreement executed in connection herewith, Liberty and the Company expressly agree that NYSCRF shall not be liable personally or otherwise for any breach or default by NYSCRF under this Agreement or any other agreement executed in connection with this Agreement, except to the extent of, and only to the extent of, the NYSCRF’s Partnership Interest in the Company. Except only for NYSCRF’s Partnership Interest in the Company, no assets of NYSCRF may be liened, encumbered, attached, levied or executed upon to satisfy any liability of or judgment against NYSCRF arising out of this Agreement or any other agreement executed in connection with this Agreement. This Section 11.4 shall survive Closing.

     12. RISK OF LOSS

     If, prior to Closing, the Property or any part thereof shall be condemned or destroyed or materially damaged by fire or other casualty (that is, damage or destruction that NYSCRF reasonably estimates will cost in excess of [The confidential material contained herein has been omitted and has been separately filed with the Commission.] to repair or restore or that materially impedes access to the Property or any material part thereof), NYSCRF shall elect to do one of the following, which election shall be made not later than the later of (i) ten (10) days prior to Closing, or (ii) ten (10) days following the date NYSCRF receives written notice of the condemnation or material damage: (A) terminate this Agreement as to the Contributed Entity that owns the affected Parcel only, whereupon the parties shall negotiate an equitable reduction in the Contribution Amount hereunder or, if the parties do not reach agreement on such a reduction within thirty (30) days after such casualty, NYSCRF shall be entitled to terminate this Agreement in its entirety; or (B) consummate the transaction contemplated by this Agreement without terminating this Agreement as to the affected Parcel notwithstanding such condemnation, destruction or material damage. If NYSCRF elects to consummate the

20

transaction contemplated by this Agreement without terminating this Agreement as to the Contributed Entity that owns the affected Parcel, the Company shall be entitled to receive all of the condemnation proceeds or settle the loss under all policies of insurance applicable to the destruction or damage and receive all of the proceeds of insurance applicable thereto, and Liberty shall, at Closing and thereafter, execute and deliver to the Company all required proofs of loss, assignments of claims and other similar items. If there is any other damage or destruction (that is, damage or destruction that NYSCRF reasonably estimates will cost [The confidential material contained herein has been omitted and has been separately filed with the Commission.] or less to repair or restore, or that does not materially impede access to the Property or any material part thereof), Liberty shall either completely repair or cause to be repaired such damage prior to Closing in a manner reasonably satisfactory to NYSCRF or, at NYSCRF’s option, assign all insurance claims pertaining to such damage or destruction to the Company by executing and delivering to the Company at Closing and thereafter all required proofs of loss, assignments of claims and other similar items.

     Notwithstanding anything herein, Liberty shall be entitled to receive and retain, and shall not be required to assign, any insurance proceeds for loss of the rents to have been paid prior to Closing.

          (a) Liberty has not received any written notice of any civil, criminal or administrative suit, claim, hearing, violation, investigation, proceeding or demand against the Property or against Liberty or the Company with respect to the Property relating in any way to a release or use of Hazardous Materials or compliance with Hazardous Materials Laws.

          (a) Liberty hereby agrees to indemnify, defend and hold harmless NYSCRF and the Company from and against any Losses arising out of any material misrepresentation by Liberty in the representations and warranties set forth in Section 13.2 or by any willful breach of the covenants set forth in Section 13.3.

22

          (b) Assumption of Defense.

               (i) If a party entitled to indemnification hereunder (the “Indemnified Party”) notifies the party liable for such indemnification (the “Indemnifying Party”) of any claim, demand, action, administrative or legal proceeding, investigation or allegation adverse to the Indemnified Party and as to which the indemnity provided for in Section 13.4(a) applies (a “Potential Claim”), Indemnifying Party shall assume on behalf of Indemnified Party and conduct with due diligence and in good faith the investigation and defense thereof and the response thereto and shall be entitled, at Indemnifying Party’s sole discretion, to settle or otherwise dispose of any such Potential Claim; provided, that Indemnifying Party shall have the right to cure such matter that is the subject of the Potential Claim (subject to the rights of the owner of the Property at the time of such cure to approve the manner of such cure) if such cure will not result in additional liability or material loss of rights to Indemnified Party, and provided further that Indemnified Party have the right to be represented by advisory counsel of its own selection and at its own expense; and provided further, that if any such claim, demand, action, proceeding, investigation or allegation involves both Indemnifying Party and Indemnified Party and Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are inconsistent with or in addition to those available to Indemnifying Party, then Indemnified Party shall have the right to select separate counsel reasonably acceptable to Indemnifying Party to participate in the investigation and defense of and response to such claim, demand, action, proceeding, investigation or allegation on its own behalf at Indemnifying Party’s expense.

               (ii) If any claim, demand, action, proceeding, investigation or allegation arises as to which the indemnity provided for in this Section 13.4 applies, and Indemnifying Party fails to assume as soon as reasonably practical the defense of Indemnified Party, then Indemnified Party may contest (or, with the prior written consent of Indemnifying Party, settle) the claim, demand, action, proceeding, investigation or allegation at Indemnifying Party’s expense using counsel selected by Indemnified Party and reasonably acceptable to Indemnifying Party.

          (c) Notice of Losses. If Indemnified Party receives a written notice of Losses that Indemnified Party believes are covered by this Section 13.4, then Indemnified Party shall promptly furnish a copy of such notice to Indemnifying Party. The failure to so provide a copy of the notice to Indemnifying Party shall not excuse Indemnifying Party from its obligations under this Section 13.4; provided, that if Indemnifying Party is unaware of the matters described in the notice and such failure renders unavailable defenses that Indemnifying Party might otherwise assert, or precludes actions that Indemnifying Party might otherwise take to minimize its obligations hereunder, then Indemnifying Party shall be excused from its obligation to indemnify Indemnified Party against assessments, fines, costs and expenses, if any, which would not have been incurred but for such failure. For example, if Indemnified Party fails to provide Indemnifying Party with a copy of a notice of an obligation covered by the indemnity set out in Sections 13.4(a) and Indemnifying Party is not otherwise already aware of such obligation, and if as a result of such failure Indemnified Party becomes liable for penalties and interest covered by the indemnity in excess of the penalties and interest that would have accrued if Indemnifying Party had been promptly provided with a copy of the notice, then Indemnifying Party will be excused from any obligation to Indemnified Party to pay the excess and Indemnified Party shall indemnify Indemnifying Party with respect to any such excess.

          (d) Rights Cumulative. The rights of NYSCRF and the Company under this Article 13 shall be in addition to any other rights and remedies of NYSCRF and the Company against Liberty pursuant to CERCLA and NYSCRF and the Company each expressly retain any right of reimbursement or contribution thereunder.

23

     14. NO ASSUMPTION

     14.1 No Assumption. The Company is not and is not deemed to be, a successor of Liberty, it being understood that Liberty is contributing to and the Company is acquiring only the Contributed Interests and the Purchase Money Loan Documents, subject to the Merger Loan, the Liberty Loan and the Assumed Financing, and the rights and obligations arising thereunder; and it is expressly understood and agreed that, except as may otherwise be expressly provided in this Agreement and in the documents delivered at the Closing, NYSCRF has not and does not hereby assume or agree to assume any liability whatsoever of Liberty.

     15. NOTICES

     15.1 Notices. Any notice, request, demand, instruction or other communication to be given to either party hereunder, except those required to be delivered at the Closing, shall be in writing, and shall be deemed to be delivered (a) upon receipt, if delivered by facsimile, (b) upon receipt or rejection if sent by hand delivery or (c) upon delivery to a nationally recognized overnight air courier service such as UPS or Federal Express, each addressed as follows:
