THIS PARTNERSHIP INTEREST PURCHASE AGREEMENT (this “Agreement”) dated as of July 31, 2013 by and among LIBERTY PROPERTY LIMITED PARTNERSHIP, a Pennsylvania limited partnership (“Buyer”), CABOT INDUSTRIAL VALUE FUND III MANAGER, LIMITED PARTNERSHIP, a Massachusetts limited partnership (the “LP Seller”), and CABOT INDUSTRIAL VALUE FUND III, INC., a Maryland corporation (“General Partner”) and the sole general partner of CABOT INDUSTRIAL VALUE FUND III OPERATING PARTNERSHIP, L.P., a Delaware limited partnership (“Partnership”) and solely for purposes of Section 5.17, LIBERTY PROPERTY DEVELOPMENT CORP. and CABOT III — PA1W01, L.P.  LP Seller and General Partner are sometimes referred to herein collectively as the “Seller Parties” or individually as a “Seller Party.”  A list of the defined terms used in this Agreement and the Section where each is defined is set forth on Schedule A attached hereto.

WHEREAS, LP Seller is the owner and holder of all of the limited partnership interests in the Partnership as set forth on Schedule B hereto (the “LP Interests”);

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Partnership Interest Purchase, and also to prescribe various conditions to the Partnership Interest Purchase.

NOW, THEREFORE, in consideration of the premises and the mutual representations, warranties, covenants and agreements contained herein, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I - THE PARTNERSHIP INTEREST PURCHASE

1.1                               Purchase and Sale of Partnership Interests.  Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, each Seller Party shall sell, convey, assign, transfer and deliver to Buyer, and Buyer shall purchase from each Seller Party, all of such Seller

Party’s right, title and interest as of the Closing Date, in and to the Partnership Interests set forth next to such Seller Party’s name on Schedule B hereto, free and clear of all Liens.

1.2                               Closing.  The closing of the Partnership Interest Purchase (the “Closing”) will take place at 10:00 a.m., local time, on the date mutually agreed upon by the parties, which shall be no later than the second (2nd) Business Day after satisfaction or waiver of the conditions set forth in Article VI (excluding the delivery of any documents to be delivered at the Closing by any of the parties hereto so long as the requirement to deliver such documents is capable of being satisfied) (the “Closing Date”); provided, however, the Closing shall not occur prior to October 1, 2013.  “Business Day” means each day, other than a Saturday, Sunday or other day on which banks in New York, New York are required by Law to close.  The Closing shall occur by means of deposits and instructions with Land Services USA and U.S. Bank N.A. consistent with the terms, conditions and requirements of this Agreement.

1.3                               Purchase Price.  Subject to the terms and conditions of this Agreement, in exchange for all of its Partnership Interests, the Seller Parties shall receive from Buyer, and Buyer shall pay, or cause to be paid, to the Seller Parties cash in an amount, without interest, equal to the following consideration (the “Purchase Consideration”):

(a)                                 at the Closing, an amount of cash equal to $1,475,000,000 (the “Purchase Price”) as adjusted, pursuant to Sections 1.4(a) and 1.4(b) and as otherwise expressly permitted in this Agreement (such cash to be allocated among the Seller Parties pro-rata in accordance with the Seller Parties’ respective percentage interests set forth on Exhibit A hereto; provided, that the amount payable to the Seller Parties on the Closing Date shall be calculated using the Estimated Closing Adjusted Working Capital as finally determined pursuant to Section 1.4 for the purposes of the Section 1.4), less:

(i)                                     the amount applied to the repayment of any outstanding Indebtedness as provided in Section 5.9;

(ii)                                  the amount of Mortgage Debt (as defined below) assumed or repaid as provided in Section 5.10;

(iii)                               the amount of the Indemnification Escrow Amount and the Post-Closing Adjusted Escrow Amount placed into escrow at the Closing as provided in Section 1.5(b) and the Escrow Agreement;

(iv)                              the amount of the Philadelphia Property Purchase Price (as defined below); and

(v)                                 $6,000,000, which represents the amount of Buyer’s expenses incurred in connection with the transactions contemplated hereby in respect of which the Seller Parties hereby agree to reimburse Buyer at Closing out of the Purchase Price; and

(b)                                 following the Closing, a portion of the Indemnification Escrow Amount if and when due, such portion, if any, to be subject to, and determined in accordance with, the terms and conditions of Article VII and the Escrow Agreement; and

2

(c)                                  following the Closing, a portion of Post-Closing Adjusted Escrow Amount if and when due, such portion, if any, to be subject to, and determined in accordance with, the terms and conditions of Section 1.4 and the Escrow Agreement.

The amount payable to the Seller Parties at Closing calculated by clause (a) of the foregoing sentence is referred to herein as the “Closing Cash Payment.”

1.4                               Adjustment to Closing Cash Payment.

(a)                                 Prior to the Closing Date, the Seller Parties shall in good faith prepare an estimate of the Pro-Rated Adjustment (the “Estimated Pro-Rated Adjustment”).  Not later than five (5) Business Days prior to the Closing Date, the Seller Parties shall deliver to Buyer a statement setting forth the calculation of the Estimated Pro-Rated Adjustment in sufficient detail, together with full supporting information, to enable Buyer to verify all items and amounts. In connection with common area maintenance and other expense pass throughs to tenants, the Seller Parties shall provide Buyer with respect to the Partnership Properties a schedule, broken down by building, and using the closed-out August 2013 numbers, showing total pass-through operating expenses vs. total collected pass-through operating expenses (in each case including estimates where appropriate) and showing estimated overage or shortfall by building. Any provision to the contrary herein notwithstanding, to the extent the estimated reconciliation reveals that operating and other reconcilable expenses were under collected for the period, Buyer shall adjust said amounts with the Seller Parties on an as and if collected basis in connection with the tenant reconciliation contemplated under Section 1.4(d).  The Estimated Pro-Rated Adjustment shall be subject to Buyer’s reasonable approval.  As provided in Section 1.3 hereof, the Closing Cash Payment shall be adjusted, dollar for dollar, up or down, as appropriate, by the Estimated Pro-Rated Adjustment (i.e., if the Estimated Pro-Rated Adjustment is a positive number, Buyer will pay the Estimated Pro-Rated Adjustment in cash at Closing in addition to the Purchase Price; if the Estimated Pro-Rated Adjustment is a negative number, Buyer will receive a credit at Closing for such amount).  The parties agree that the adjustment based on Adjusted Working Capital described in Section 1.4(b) is not intended to be duplicative of the adjustment based on the Pro-Rated Adjustment and, accordingly, the effects of the Pro-Rated Items and other items included in the calculation of the Pro-Rated Adjustment are not to be taken into account in calculating the Adjusted Working Capital.

(b)                                 Prior to the Closing Date, the Seller Parties shall in good faith prepare an estimated combined consolidated balance sheet of the Partnership, and the Partnership Subsidiaries, as of the close of business on the Closing Date (the “Estimated Closing Date Balance Sheet”).  The Estimated Closing Date Balance Sheet shall be prepared in accordance with generally accepted accounting principles (“GAAP”) consistently applied on a fair value basis and otherwise consistent with the methodology used to prepare the Most Recent Balance Sheet and shall also include a calculation of Adjusted Working Capital, which shall be subject to Buyer’s reasonable approval, together with such supporting information as may reasonably be requested, to enable Buyer to verify all items and amounts. Not later than five (5) Business Days prior to the Closing Date, the Partnership shall deliver to Buyer the Estimated Closing Date Balance Sheet.  As provided in Section 1.3 hereof, the Closing Cash Payment shall be adjusted, dollar for dollar, up or down, as appropriate, by the amount that the Adjusted Working Capital set forth on the Estimated Closing Date Balance Sheet (the “Estimated Closing Adjusted

3

Working Capital”) exceeds or is less than $0.00 (the “Base Adjusted Working Capital”). The Seller Parties will use reasonable efforts to reduce payables, collect receivables and take other appropriate actions prior to Closing, to the extent practicable, to minimize the amount of the Estimated Closing Adjusted Working Capital.

(c)                                  As soon as practical after the Closing Date, Buyer shall review the Partnership’s and the Partnership Subsidiaries’ books and records and also shall review the Estimated Closing Date Balance Sheet in accordance with GAAP consistently applied on a fair value basis, and otherwise consistent with the methodology used to prepare the Most Recent Balance Sheet and the provisions of this Section 1.4, and following such review, Buyer shall make any adjustments necessary thereto consistent with the provisions of this Section 1.4 (the Estimated Closing Date Balance Sheet, as so adjusted, shall be called the “Post-Closing Balance Sheet”).  Buyer shall, within ninety (90) days after the Closing Date, deliver the Post-Closing Balance Sheet to the Seller Parties, together with worksheets which detail any adjustments and the basis of any such adjustments and any other information that the Seller Parties may reasonably request in order to verify or evaluate such adjustments; provided, however, that if the Seller Parties have not prepared any tax returns for jurisdiction in which the Partnership or any Partnership Subsidiary is required to pay taxes within the eighty (80) day period pursuant to Section 5.4, such ninety (90) day period shall extend until ten (10) days following the completion of all such tax returns (which completion shall in no event be later than 120 days following the Closing and the Seller Parties shall keep Buyer reasonably informed of the status of completion of such returns and in any event notify Buyer upon completion).  If Buyer fails to deliver the Post-Closing Balance Sheet to the Seller Parties within such ninety (90) day period or within ten (10) days following the completion of all such tax returns, as the case may be, then the Estimated Closing Date Balance Sheet shall be deemed to be the Post-Closing Balance Sheet.  The Post-Closing Balance Sheet, and the Adjusted Working Capital, shall be binding upon the parties upon approval in writing (or upon “deemed approval” pursuant to this Section) of such Post-Closing Balance Sheet by the Seller Parties and Buyer.  The Seller Parties shall be deemed to have approved the Post-Closing Balance Sheet and the Adjusted Working Capital at the Closing reflected thereon unless the Seller Parties has delivered a written statement specifying any disagreement therewith within fifteen (15) days following its receipt of the Post-Closing Balance Sheet and accompanying worksheets (a “Seller Objection Notice”).  If the Seller Parties do not agree with the Post-Closing Balance Sheet and the calculation of Adjusted Working Capital at the Closing stated thereon, then Buyer and the Seller Parties shall use good faith efforts to resolve their differences.  In the event that Buyer and the Seller Parties cannot resolve such differences, within fifteen (15) days following receipt by Buyer of the Seller Objection Notice, then Buyer and the Seller Parties shall select a nationally recognized independent accounting firm mutually satisfactory to Buyer and the Seller Parties to resolve such dispute (the “Neutral Auditor”).  The Neutral Auditor shall review the Post-Closing Balance Sheet and, as soon as possible after its appointment, shall make any adjustments necessary thereto, and upon completion of such review, such Post-Closing Balance Sheet (and the calculation of the Adjusted Working Capital at the Closing stated thereon) as determined by the Neutral Auditor shall be binding upon (and deemed approved by) Buyer and the Seller Parties.  The Adjusted Working Capital at the Closing stated on the version of the Post-Closing Balance Sheet that is ultimately binding on the parties pursuant to this Section 1.4(c) shall be referred to as the “Closing Adjusted Working Capital.”  If such a review is conducted by the Neutral Auditor, then the party (i.e., Buyer, on the one hand, or the Seller Parties, on the other hand) whose last proposed offer for the

4

settlement of the items in dispute prior to the selection of the Neutral Auditor, taken as a whole, was farther away from the final determination by the Neutral Auditor pursuant to the preceding sentence, shall pay all fees and expenses of the Neutral Auditor associated with such review; provided, that the sole and exclusive source for any amounts owed by the Seller Parties shall be the Post-Closing Adjustment Escrow Amount, to the extent available.

(d)                                 Within sixty (60) days following Closing, the Seller Parties shall prepare and deliver to Buyer Seller Parties’ final proposed 2013 year to date of Closing reconciliations with tenants under the Partnership Space Leases (which may include estimates as appropriate, with final information to be provided when available), together with all necessary supporting documentation (sufficient to satisfy the requirements of any tenant audit). After Buyer has completed 2013 year-end reconciliations with the tenants under the Partnership Space Leases, but in no event later than June 30, 2014, Buyer shall prepare and present to the Seller Parties for their approval a calculation of the re-proration of the Pro-Rated Items (excluding leasing commissions, and Tenant Inducements that are allocated according to Sections 1.4(g)(v)), based upon the actual amount of such items incurred or received by the parties for the year or other applicable fiscal period, together with such supporting documentation as reasonably requested by the Seller Parties.  Any disagreement shall be resolved by a Neutral Auditor in a manner consistent with Section 1.4(c).  The re-proration that is ultimately agreed to or binding on the parties is the “Closing Pro-Rated Adjustment”.  To the extent that the Closing Pro-Rated Adjustment is different from the Estimated Pro-Rated Adjustment (excluding in each case leasing commissions and Tenant Inducements that are all allocated according to Section 1.4(g)(v), then, within three (3) Business Days following the determination of the Closing Pro-Rated Adjustment, Buyer and the Seller Parties shall appropriately adjust for such difference either (i) if there is an adjustment in favor of Buyer, by jointly authorizing and directing the Escrow Agent to pay to Buyer from the Post-Closing Adjusted Escrow Amount within three (3) Business Days following delivery of such authorization an amount equal to the difference between such amounts, and (ii) if there is an adjustment in favor of the Seller Parties, by Buyer paying to the Seller Parties the difference between such amounts by wire transfer of immediately available funds.

(e)                                  Within three (3) Business Days following the determination of the Closing Adjusted Working Capital in accordance with Section 1.4(c), (i) in the event the Closing Adjusted Working Capital, is less than the Estimated Closing Adjusted Working Capital, Buyer and the Seller Parties shall jointly authorize and direct the Escrow Agent to pay to Buyer  from the Post-Closing Adjusted Escrow Amount within three (3) Business Days following delivery of such authorization an amount equal to the difference between such amounts, and (ii) in the event the Closing Adjusted Working Capital, is greater than the Estimated Closing Adjusted Working Capital, Buyer shall pay to the Seller Parties the difference between such amounts by wire transfer of immediately available funds.

(f)                                   Buyer shall use its reasonable efforts for six (6) months after the Closing Date (and, with respect to sums, if any, due to Seller Parties relating to collections resulting from the 2013 reconciliation with tenants, for six (6) months following the delivery of the annual reconciliation statements) to collect any Uncollected Tenant Payments; provided, however, Buyer will not be obligated to commence any suit or proceeding to collect any Uncollected Tenant Payments or to evict any tenant for the failure to pay such sums.  Buyer shall not be

5

obligated to thereafter pursue any such past due amounts.  Buyer will be obligated to promptly pay to the Seller Parties an amount equal to any Uncollected Tenant Payments not accounted for in the calculation of the Closing Pro-Rated Adjustment only to the extent that such Uncollected Tenant Payments are subsequently collected within said six (6) month period, and subject to the provisions of Section 1.4(g)(vi)(E).

(g)                                  As used in this Section 1.4:

(i)                                     “Adjusted Working Capital” means Current Assets minus Current Liabilities, as adjusted to net out the effect of the Pro-Rated Items and the other items included in the calculation of the Pro-Rated Adjustment.

(ii)                                  “Current Assets” means and includes all accounts receivable (excluding Uncollected Tenant Payments), cash, cash equivalents and such other current assets of the Partnership and the Partnership Subsidiaries, in each case as determined in accordance with GAAP consistently applied on a fair value basis.

(iii)                               “Current Liabilities” means and includes all accounts payable, accrued expenses, expenses of the Partnership and the Partnership Subsidiaries under Section 3, accrued but unpaid taxes, deferred revenues and all other liabilities of the Partnership, and the Partnership Subsidiaries, in each case as determined in accordance with GAAP consistently applied on a fair value basis.  Current Liabilities shall not include any portion of Mortgage Debt.

(iv)                              “Pro-Rated Adjustment” shall equal (A) the sum of (x), with respect only to the post-Closing determination of the Closing Pro-Rated Adjustment under Section 1.4(d), all income of the Partnership and the Partnership Subsidiaries on a combined consolidated basis attributable to the Pro-Rated Items for periods prior to the Closing Date that is collected after the Closing Date (subject to the provisions of Section 1.4(g)(vi)(E)), plus (y) all expenses of the Partnership and the Partnership Subsidiaries on a combined basis attributable to the Pro-Rated Items for periods on or after the Closing Date that have been paid as of the Closing Date, minus (B) the sum of (x) all income of the Partnership and the Partnership Subsidiaries on a combined consolidated basis attributable to the Pro-Rated Items for periods on or after the Closing Date that has been collected as of the Closing Date, plus (y) all expenses of the Partnership and the Partnership Subsidiaries on a combined consolidated basis attributable to the Pro-Rated Items for periods prior to the Closing Date that have not been paid as of the Closing Date.  Income and expenses attributed to the Pro-Rated Items will be allocated among these time periods as follows, except as otherwise specified herein with respect to a Pro-Rated Item: (A) income and expenses relating to the Pro-Rated Items with respect to periods beginning prior to the Closing Date and ending on or after the Closing Date will be allocated based on a 365 day year in the applicable period (e.g., collected rent for the month in which the Closing occurs will be prorated based on the number of days in the month) and (B) all other income and expenses will be allocated to the period to which it relates (e.g., collected rent for a month beginning after the Closing Date shall be credited in full to that time period).

6

(v)                                 The Pro-Rated Adjustment will be: (A) increased by the unamortized cost (evenly amortized over the initial rent term) of leasing commissions and Tenant Inducements (which for all purposes of this Section 1.4(g)(v) excludes any free rent) borne by the lessor with respect to Partnership Space Leases entered into on or after July 20, 2013 and new leases and Lease Modifications executed in accordance with Sections 4.2 and 4.3 and any other new lease executed that does not require notice to or approval of Buyer, in each case that have been paid on or before the Closing Date, but only to the extent that such costs with respect to Lease Modifications are consistent with the leasing parameters referenced in Section 4.2 (the “Leasing Parameters”) unless otherwise reasonably approved by Buyer, (B) decreased by the amount of any leasing commissions and Tenant Inducements with respect to the current terms of the Partnership Space Leases entered into prior to July 20, 2013 that have not been paid or provided on or before the Closing Date, and (C) decreased by the amortized cost (evenly amortized over the initial rent term) (i.e. the costs attributable to the pre-Closing portion of the term (following the rent commencement date)) of leasing commissions and Tenant Inducements borne by the lessor with respect to Partnership Space Leases entered into on or after July 20, 2013 and new leases and Lease Modifications executed in accordance with Sections 4.2 (except as provided at (D) below) and 4.3, in each case that have not been paid on or before the Closing Date, and (D) decreased by the amount of any unpaid leasing commissions and Tenant Inducements borne by the lessor with respect to Lease Modifications executed in accordance with Section 4.2 or that do not require notice to or approval of Buyer, in each case which are not consistent with the Leasing Parameters and not otherwise approved by Buyer.  The Estimated Pro-Rated Adjustment shall include an estimate of the costs of the items under clauses (A) through (D) above.  Buyer and the Seller Parties shall jointly authorize and direct the Escrow Agent to promptly pay to Buyer or the Seller Parties, as the case may be, out of the escrow established under the Escrow Agreement, the amount by which the aggregate Estimated Pro-Rated Adjustment for such items is less than, or greater than, the final aggregate Pro-Rated Adjustment for such items.

(vi)                              The “Pro-Rated Items” shall consist of the following:

(A)                               All real and personal property taxes and installments of special assessments with respect to Partnership Properties through the year in which the Closing occurs on an accrual basis (regardless of whether such taxes and special assessments are then due and payable or delinquent, but with such accruals modified to reflect custom in certain jurisdictions as set forth on Schedule C attached hereto).  If any such taxes or assessments for the fiscal year during which the Closing Date occurs are not finally determined, then the tax or assessment figures for the immediately prior fiscal year shall be used (provided, however, if the current year’s assessment is available, real estate taxes will be prorated based upon the prior year’s millage applied to the current year’s assessment).  To the extent that any real property taxes assessed with respect to the fiscal year in which the Closing occurs have not been finally determined by the applicable Government Entity on or before June 30, 2014, then the Seller Parties and Buyer shall act reasonably and in good

7

faith to agree on an estimated amount of such real property taxes, which agreed-upon estimate shall be used for the re-proportion of the Pro-Rated Items and the Closing Pro-Rated Adjustment.  If the Seller Parties and Buyer do not reach agreement on such estimated real property taxes on or before June 30, 2014 despite such good faith reasonable efforts, then such estimated taxes shall be finally determined by a mutually agreed upon real property tax consulting firm with experience in the applicable jurisdiction and, if the Seller Parties and Buyer do not agree on such consulting firm prior to June 30, 2014, then such consulting firm shall be selected by the national head of the real property tax consulting group (or comparable position) at KPMG.  Such consulting firm shall be required to complete such determination within 60 days after the June 30, 2014; provided, however, that if such real property taxes are finally determined during such interim period, then such real property taxes will be used.  The determination of such consulting firm shall be final and binding on the Seller Parties and Buyer, and the costs of such consulting firm (and KPMG, if applicable) shall be paid fifty (50) percent by the Seller Parties and fifty (50) percent by Buyer.

(B)                               All amounts owed or accrued with respect to, or under the documents governing, the Mortgage Debt (other than repayments of principal).

(C)                               All operating expenses and other apportionable expenses, including, but not limited to, assessments and other obligations under private covenants and easements, maintenance expenses, management fees (if applicable), and all amounts owed or accrued with respect to electricity, gas, water, sewer or other utility usage at the Partnership Properties.  Partnership will use reasonable efforts to cause all meters for electricity, gas, water, sewer or other utility usage at the Partnership Properties to be read on the Closing Date.  The utility charges based on the most recent bills shall be used for the purposes of calculating the Estimated Pro-Rated Closing Adjustment.  Partnership shall provide notice to Buyer five (5) days prior to the Closing Date setting forth (i) whether utility meters will be read as of the Closing Date and (ii) a copy of the most recent bills for the utility charges at the Partnership Properties.

(D)                               Collected rents for the current period and security deposits (the full amount thereof to be credited to Buyer with interest earned thereon required to be paid to the applicable tenant and not so paid, if any); prepaid rentals; common area maintenance charges; promotional charges; service charges; tax charges; and all other incidental expenses and charges paid by current, former or prospective tenants at the Partnership Properties, in each case only to the extent collected for the current period and any future periods.

8

(E)                                All rents and related charges for the current period in which the Closing occurs and prior rental periods (including common area maintenance charges, annual adjustments thereto and annual tenant reconciliations) that are collected after the Closing Date, less any reasonable third party out-of-pocket expenses of collection thereof (“Uncollected Tenant Payments”).  For the avoidance of doubt, Uncollected Tenant Payments shall not be pro-rated unless and until they are collected, and in such case, only with respect to the post-Closing determination of the Closing Pro-Rated Adjustment under Section 1.4(d).  All Uncollected Tenant Payments shall be first applied to amounts due and payable for rental periods accruing after the Closing Date.

(F)                                 Lease termination payments paid or payable by tenants in respect of the termination of any Partnership Space Lease occurring (or termination right exercised) during the period between July 20, 2013 and the Closing Date.  Such termination payments shall be apportioned between the Seller Parties and Buyer, with Buyer receiving a credit in an amount equal to the total lease termination payment multiplied by the quotient of (i) the number of days from the Closing Date through the scheduled expiration of the current Lease term (but for the early termination), divided by (ii) the number of days from the early termination date through the scheduled expiration of the current Lease term (but for the early termination) and without giving effect to any unexercised extensions.

(vii)                           The Pro-Rated Items shall not include taxes, utilities or other amounts to the extent that they are directly paid by a tenant to the applicable service provider or taxing authority.

1.5                               Signing Deposit; Escrow and Escrow Agreement.

(a)                                 Within one day following the date hereof, Buyer will deliver to US Bank N.A. (the “Escrow Agent”), a sum equal to Twenty-Five Million Dollars ($25,000,000.00) as a deposit (together with any interest earned thereon while held in escrow, the “Signing Deposit”).  Time is of the essence with respect to the funding of the Signing Deposit, and failure to timely fund the Signing Deposit shall constitute a default by Buyer under this Agreement entitling Seller Parties to terminate this Agreement.  The Signing Deposit shall be held in escrow by the Escrow Agent in an interest-bearing account pursuant to and in accordance with the escrow agreement attached hereto as Exhibit A and executed on the date hereof (the “Deposit Escrow Agreement”).  At the Closing, an amount of the Signing Deposit equal to the full amount of the Indemnification Escrow Amount shall be retained by the Escrow Agent as the Indemnification Escrow Amount pursuant to Section 1.5(b), an amount of the Signing Deposit equal to the full amount of the Post-Closing Adjustment Escrow Amount shall be retained by the Escrow Agent as the Post-Closing Adjustment Escrow Amount pursuant to Section 1.5(b), and the remainder of the Signing Deposit shall be paid to the Seller Parties and the entire Signing Deposit shall be credited against the Purchase Consideration pursuant to Section 1.3.  If this Agreement is

9

terminated prior to the Closing pursuant to Article VIII, the Signing Deposit will be handled as set forth in such provisions.

(b)                                 Section 1.4 provides for possible post-closing adjustments of the Closing Cash Payment and Article VII provides that Buyer is entitled to indemnification from and against certain Losses.  At the Closing, the Seller Parties, Buyer and the Escrow Agent shall enter into an escrow agreement substantially in the form Exhibit B attached hereto (the “Escrow Agreement”).  The Escrow Agreement provides for the formation of two escrow funds to accommodate such adjustments and indemnification rights.  At the Closing, the parties shall cause the Escrow Agent to (i) deposit cash held pursuant to the Deposit Escrow Agreement into one escrow fund a sum equal to [the confidential material contained herein has been omitted and has been separately filed with the Commission] (as contemplated by Section 1.5(a) above), which shall constitute a portion of the Purchase Consideration and secure and serve as the sole and exclusive remedy for satisfying Buyer’s rights to payments under Section 1.4 (the “Post-Closing Adjustment Escrow Amount”), and (ii) deposit cash held pursuant to the Deposit Escrow Agreement into the second escrow fund a sum equal to Ten Million Dollars ($10,000,000.00) (as contemplated by Section 1.5(a) above), which shall constitute a portion of the Purchase Consideration and which shall secure and serve as the sole and exclusive remedy for satisfying Buyer’s rights to indemnification payments under Article VII of this Agreement (the “Indemnification Escrow Amount” and together with the Post-Closing Adjustment Escrow Amount, the “Escrow Amount”).  The Escrow Amount will be funded by the Signing Deposit.

(c)                                  Buyer, Partnership and the Seller Parties shall treat the Escrow Agreement and the contingent consideration payable pursuant to Section 1.4 as causing the Partnership Interest Purchase to constitute a contingent payment sale reportable under the installment sale method as provided in Section 453 of the Internal Revenue Code of 1986, as amended (the “Code”) and United States Treasury Regulation Section 15A.453-1(c).  Consistent with the foregoing and with Proposed Treasury Regulations Section 1.468B-8(c), for all relevant tax purposes the parties hereto shall treat Buyer as the owner of the Signing Deposit, the Post-Closing Adjustment Escrow Amount and the Indemnification Escrow Amount and shall not treat any amount deposited in the Signing Deposit, the Post-Closing Adjustment Escrow Amount and the Indemnification Escrow Amount or owing pursuant to Section 1.4 as having been actually or constructively paid to the Seller Parties until such amount is released or paid to the Seller Parties pursuant to the terms of the Deposit Escrow Agreement, the Escrow Agreement or the relevant Section of this Agreement, as applicable.  Nothing in this Section 1.5(c) is intended or shall be construed as limiting any limited partner’s right to elect not to report on the installment method pursuant to Treasury Regulation Section 15A. 453-1(d). The parties hereto agree that to the extent income and earnings on the Signing Deposit, the Post-Closing Adjustment Escrow Amount, and/or the Indemnification Escrow Amount exceed imputed interest under the relevant provisions of the Code, such excess shall be treated as additional stated interest for U.S. federal income tax purposes. The intention of the preceding sentence is to ensure that the rights of the Seller Parties to any amounts in escrow are not treated as part of a contingent payment sale lacking a stated maximum selling price.

10

1.6                               Intentionally Omitted.

1.7                               Payment Procedures.

(a)                                 Payments.  Buyer shall make payment of all amounts to be paid by Buyer to the Seller Parties under this Agreement as per written instructions provided by such Seller Parties in advance.

(b)                                 No Further Ownership Rights in Partnership Interests.  At the Closing, holders of Partnership Interests shall cease to be, and shall have no rights as Partners other than to receive the Purchase Consideration under this Article I.  After the Closing, there shall be no further registration of transfers on the transfer books of the Partnership of the Partnership Interests that were outstanding immediately prior to the Closing.

(c)                                  Withholding Rights.  Buyer or the Seller Parties (or the Escrow Agent or any other agent or affiliate of the foregoing), as applicable, shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, and the rules and regulations promulgated thereunder, or any provision of state, local or foreign tax law.  To the extent that amounts are so withheld, and are paid to the appropriate taxing authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

1.8                               Purchase Price Allocation.  The Purchase Price shall be allocated among the Partnership Properties prior to the Closing as determined by Buyer. No party shall take any position for Tax, accounting or other purposes that is inconsistent with such allocation except to the extent otherwise required by a final determination by any tax or other regulatory authority.  Buyer shall keep the Seller Parties reasonably informed throughout its process of determination of such allocation.

1.9                               Tax Treatment of Partnership Interest Purchase.  It is the intention of the parties hereto that  consistent with Revenue Ruling 99-6, 1999-1 CB 432 (Situation 2), the transaction contemplated by this Agreement shall be treated as (A) a sale by the Seller Parties of one hundred (100) percent of the Partnership Interests to Buyer and (B) a purchase by Buyer of the Partnership’s assets.

37

relating to any of the Partnership Space Leases or Ground Leases.  Notwithstanding anything to the contrary in this Section 4.2, Seller Parties may cause the Partnership or applicable Partnership Subsidiary to enter into any Lease Modification in the nature of an extension or renewal of the term of a Partnership Space Lease so long as such Partnership Space Lease and Lease Modification meet all of the following criteria:  (i) the applicable leased premises under such Partnership Space Lease, both before and after giving effect to such Lease Modification, are less than 7,500 square feet in the aggregate; (ii) such Lease Modification does not extend the term of such Partnership Space Lease by more than three (3) years; (iii) such Lease Modification does not provide for additional Tenant Inducements in excess of $1.50 per square foot; and (iv) such Lease Modification does not create any new rights of first refusal, first offer or expansion.

If Seller Parties shall request Buyer’s approval to any of the foregoing matters, Buyer shall have five (5) Business Days from its receipt of such request (with all required accompanying information) to give Seller Parties notice of its approval or disapproval of such matter.  If Buyer does not timely give such notice, such matter shall be deemed approved by Buyer.

4.4                               No Solicitation.

(a)                                 From the date of this Agreement until the Closing, Seller Parties shall not, and shall not authorize or permit the Partnership or any of the Partnership Subsidiaries, or any of its or their officers, trustees, directors, partners, affiliates or employees or any investment banker, financial advisor, attorney, accountant, agent or other representative retained by it or any of its Subsidiaries (collectively, the “Seller Representatives”), directly or indirectly, to (i) solicit, initiate or knowingly encourage or knowingly facilitate any inquiries, proposals or offers with respect to an Acquisition Proposal, (ii) initiate or, participate in any discussions or negotiations regarding an Acquisition Proposal (including providing non-public information in connection therewith provided that, if provided, such non public information must also promptly be

38

provided to Buyer) or (iii) approve or recommend an Acquisition Proposal or enter into any binding merger agreement, letter of intent, ownership interest purchase agreement, asset purchase agreement or ownership interest exchange agreement, option agreement or other similar binding agreement providing for or relating to an Acquisition Proposal or enter into any agreement requiring Seller Parties to abandon, terminate or fail to consummate the transactions contemplated hereby or agree to do any of the foregoing.  “Acquisition Proposal” means (i) a merger, tender offer, recapitalization, or consolidation, or any similar transaction, involving the Partnership or any of the Partnership Subsidiaries or any Person (a “Partnership Control Person”) that, directly or indirectly, controls the Partnership, where “control” means the possession, directly or indirectly, of the power to direct or cause the direction of management policies of the Partnership, whether through the ownership of voting securities, by Contract, as trustee or otherwise, (ii) a purchase, lease or other acquisition or assumption of all or a substantial portion of the assets of the Partnership or all or a substantial portion of the assets of any of the Partnership Subsidiaries or of a Partnership Control Person, (iii) a purchase or other acquisition (including by way of merger, consolidation, share exchange or otherwise) of beneficial ownership (the term “beneficial ownership” for purposes of this Agreement having the meaning assigned thereto in Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder) of securities of the Partnership or any of the Partnership Subsidiaries or any Partnership Control Person, or (iv) any substantially similar transaction; provided, however, that the term “Acquisition Proposal” shall not include the Partnership Interest Purchase or the other transactions contemplated hereby or herein or by any of the other related documents.

(b)                                 Upon execution of this Agreement, the Seller Parties, the Partnership and the Partnership Subsidiaries shall cease immediately and shall cause to be terminated any and all existing activities, discussions or negotiations with any parties conducted heretofore with respect to an Acquisition Proposal by or on behalf of the Partnership or any of the Seller Representatives and shall inform each of the Seller Representatives of its obligations under this Section 4.2.

ARTICLE V - ADDITIONAL COVENANTS

5.1                               Due Diligence.

(a)                                 Subject to the provisions of this Article V, Seller Parties shall, and shall cause the Partnership and each of the Partnership Subsidiaries to, afford to Buyer and to the officers, employees, accountants, counsel, financial advisors and other representatives of Buyer, reasonable access during normal business hours prior to the Closing to the Partnership Properties and to all their respective books, contracts, and records and, during such period, Seller Parties shall, and shall cause the Partnership and each of the Partnership Subsidiaries to, make available promptly to the other parties such information within their possession or control concerning the Partnership’s and the Partnership Subsidiaries’ business and Partnership Properties as such other party may reasonably request, including formation documents, tax records and other additional customarily requested corporate due diligence items for the Partnership and the Partnership Subsidiaries; Partnership Space Leases and Guaranties, updated tenant financial statements, rent rolls, operating statements, the latest property tax bills and value renditions; environmental reports concerning the Partnership Properties; material governmental permits, licenses and approvals; site plans; any soils reports on the Partnership Properties; certificates of insurance and

(b)                                 Subject to the rights of the tenants of the Partnership Properties, Buyer, its agents and representatives shall have the right to inspect the Partnership Properties and make investigations thereon, including so-called “Phase I” environmental investigations; provided, however, that no so-called “Phase II” environmental investigation or testing or other invasive or destructive investigation or testing will be done without the Seller Parties’ written permission, which the Seller Parties may withhold in their sole discretion.  Upon the completion of any such inspection or test, Buyer shall restore the applicable Property to its condition prior to such inspection or test.  The Seller Parties shall have the right to have a representative present at any such inspection or test as long as such requirement does not materially delay such inspection or test.  All such inspections shall be at Buyer’s sole expense and shall be in accordance with applicable Laws, including, without limitation, Laws relating to worker safety and the proper disposal of discarded materials.

(c)                                  Each of Buyer Party agrees to indemnify, the Seller Parties, the Partnership and each Partnership Subsidiary from and against any and all Losses arising out of or resulting from the entry on any property and/or the conduct of any due diligence (as opposed to any existing condition discovered through such due diligence), by Buyer or any of their respective affiliates, associates, partners, employees, directors, officers, agents, counsel, auditors, investment bankers, representatives and advisors, except to the extent caused by the gross negligence or willful misconduct of the Partnership or its affiliates.  The foregoing notwithstanding, Buyer shall not have any liability hereunder for any claims resulting from or relating to any existing conditions, including but not limited to, any Hazardous Materials detected by Buyer’s inspections, except to the extent such existing conditions have been exacerbated due to the gross negligence or willful misconduct on the part of Buyer or any of Buyer’s representatives, agents or contractors during the course of Buyer’s inspections.  Prior to entering any Partnership Property, Buyer shall (i) obtain policies of general liability insurance which insure Buyer, its agents and representatives with liability insurance limits of not less than $2,000,000 combined single limit for personal injury and property damage and name the Partnership as an additional insured and which are with such insurance companies, provide such coverages and carry such other limits as the Seller Parties shall reasonably require, and (ii) provide the Seller Parties with certificates of insurance evidencing that Buyer has obtained the aforementioned policies of insurance.

(d)                                 Except as provided in Section 5.1(e) below, Buyer acknowledges that it has completed, and is satisfied with, its due diligence review of the Partnership and the Partnership Subsidiaries, the physical condition of the Partnership Properties, the condition of title to the Partnership Properties (including obtaining such updated title reports or title insurance

40

commitments and updated surveys as Buyer deems appropriate) and the Partnership Properties’ suitability for Buyer’s intended investment.  Buyer shall have the right to continue its inspections and investigations as provided in this Section 5, but shall have no right to terminate this Agreement as a result of such inspections and investigations.  Seller Parties shall, and shall cause the Partnership and each of the Partnership Subsidiaries to, reasonably cooperate to answer  Buyer’s reasonable questions arising out of Buyer’s continuing due diligence; provided, however, Buyer shall have no right to terminate this Agreement and receive back the Signing Deposit as the result of such questions.  The foregoing notwithstanding, nothing herein shall be construed to affect or otherwise limit Buyer’s rights under Article VI with respect to conditions of Closing or Buyer’s right to rely upon the representations and warranties provided by the Seller Parties in Article II of this Agreement.

(e)                                  Prior to the execution and delivery of this Agreement, the Partnership delivered or provided access to Buyer or its counsel, for each Partnership Property, copies of the most recent title insurance policy (each, an “Existing Policy”) and the most recent survey in the Partnership’s possession (each, an “Existing Survey”).  Through Escrow Agent, Buyer has ordered from First American Title Insurance Company (“Title Company”) title insurance commitment(s) (the “Title Commitments”) obligating the Title Company to issue for each Partnership Property a new owner’s title insurance policy or a date-down endorsement to an Existing Policy (or leasehold policy, with respect to any Partnership Properties subject to Ground Leases) (collectively, the “Owner’s Title Policies”), together with such endorsements and affirmative coverage desired by Buyer to provide primary coverage up to an insured amount agreeable to Buyer for all Partnership Properties; however, Buyer shall have the right to require re-insurance from such national underwriters identified by Buyer as needed, requested or as required by Buyer.  Notwithstanding anything to the contrary contained in this Agreement, any additional premiums incurred as a result of any re-insurance requested by Buyer shall be at Buyer’s expense.  Buyer has also ordered, prior to the date of this Agreement, at Buyer’s sole cost and expense, updates to each of the Existing Surveys (the “Survey Updates”), and Buyer shall make commercially reasonable efforts to ensure that such Survey Updates are completed by August 31, 2013.  Buyer has received and completed its review of the Title Commitments and Existing Surveys for the Partnership Properties identified on Schedule 5.1(e)-A (the “Reviewed Properties”); and as of the date hereof Buyer is still reviewing the Title Commitments and Existing Surveys for the Partnership Properties identified on Schedule 5.1(e)-B (the “Non-Reviewed Properties”). Schedule 5.1(e)-A also lists matters that Buyer believes may be Material Title Defects (as defined below) identified by Buyer with respect to the Reviewed Properties as a result of Buyer’s review thereof and, except for New Title Defects, Buyer shall have no right to object to any title or survey matters relating to the Reviewed Properties.  Buyer shall have until 5:00 p.m. eastern time on August 9, 2013 to complete its review of the Title Commitments and Existing Surveys for the Non-Reviewed Properties (the “Title Review Deadline”) and notify Seller Parties of any matters it believes may be Material Title Defects relating to the Non-Reviewed Properties.  Except for New Title Defects, Buyer shall have no right to object to any title or survey matters relating to the Non-Reviewed Properties at any time after the Title Review Deadline. Seller Parties shall, and shall cause the Partnership and each of the Partnership Subsidiaries to (all at Seller Parties’ sole cost and expense), use commercially reasonable efforts to resolve any Material Title Defects, to the extent timely raised in accordance with the requirements of this paragraph (e), and New Title Defects, in each case to Buyer’s commercially reasonable satisfaction.  Such efforts may include causing the Title Company (whether pursuant

41

to undertakings, escrows, or indemnities provided to the Title Company by Seller Parties, or otherwise) to remove such objection as an exception to title in the Owner’s Title Policy issued at Closing or affirmatively insure against the same (which insurance shall be reasonably satisfactory to Buyer in form and substance), in either case without any additional cost or liability to Buyer and without retention of any liability by the Partnership or any Partnership Subsidiary.  Any such undertakings and/or indemnities shall be funded solely out of the Indemnification Escrow Amount.  The foregoing notwithstanding, nothing herein shall be construed to affect or otherwise limit the obligations of the Seller Parties under Section 5(f) immediately below.  “Material Title Defect” means any defect or encumbrance that, based on the  standards prevailing among institutional real estate purchasers and lenders, would be deemed to materially and adversely affect the marketability, financeability, value or continued use and operation of the subject property as presently used and operated. It shall not be considered a Material Title Defect that a use or structure (including setbacks) or amount of parking is a legal nonconforming use or structure (including setbacks) or amount of parking. “New Title Defect” means any Material Title Defect of which (i) Buyer did not have prior Knowledge, (ii) was not caused by Buyer or any Person on behalf of Buyer, (iii) was not otherwise consented to by Buyer in writing, and (iv) either (A) first arising  after (1) the date of this Agreement, in the case of the Reviewed Properties, or (2) the Title Review Deadline, in the case of the Non-Reviewed Properties, or (B) first discovered by Buyer following Buyer’s receipt and review of documentation not reasonably available to Buyer prior to (1) the date of this Agreement, in the case of the Reviewed Properties, or (2) the Title Review Deadline, in the case of the Non-Reviewed Properties (including, in each case, any Survey Updates not received by Buyer by the applicable date, to the extent timely ordered and pursued by Buyer in accordance with the requirements set forth above, but in any event Buyer shall notify Seller Parties of any potential Material Title Defect raised by Survey Updates on or before September 4, 2014). The Seller Parties covenant and agree that at or prior to Closing, the Partnership shall (and regardless of whether identified by Buyer as a Material Title Defect) : (i) pay in full and cause to be canceled and discharged, all mechanics’ and contractors’ liens which encumber any Partnership Property as of the Closing Date for work performed during the Partnership’s or any Partnership Subsidiary’s period ownership (and shall pay in full or bond over at the Seller Parties’ expense any charges for such labor or materials that could give rise to such a lien), other than such liens which only encumber a tenant’s leasehold estate or are reimbursable by or otherwise the responsibility of a tenant under a Partnership Space Lease or lease executed pursuant to Section 4.3; (ii) pay all liens or encumbrances against such Partnership Property or any personal property that is used in connection therewith which evidence monetary obligations of the Partnership or any Subsidiary (excluding liens securing the Mortgage Debt) including liens for past due taxes and assessments; (iii) cause to be released any loan security documents of any the Partnership or any Subsidiary which encumbers any Partnership Property or personal property, except for the loan documents evidencing and securing the Mortgage Debt; and (iv) pay (by bonding or otherwise) and obtain the release of all judgment liens against the Partnership or any Partnership Subsidiary on such Partnership Property or personal property that is used in connection therewith.  The liens, judgments and encumbrances referred to in this Section 5.1(e) must be satisfied by the Partnership prior to or at Closing, and if not so satisfied, shall be satisfied at Closing out of the Closing Cash Payment without adjustment to the Purchase Consideration. The Seller Parties may satisfy their obligation to clear title with respect to any item described above that it contests in good faith if, without retention of any liability by the Seller Parties, the

42

Partnership or the Partnership Subsidiaries after the Closing Date, the Seller Parties either: (a) take such actions as are reasonably necessary to remove, satisfy or cure (of record or otherwise, as appropriate) such objection; (b) cause the Title Company to remove such objection as an exception to title in the Owner’s Title Policy issued at Closing or affirmatively insure against the same (which insurance shall be reasonably satisfactory to Buyer in form and substance), in either case without any additional cost or liability to Buyer and without retention of any liability by the Partnership or any Partnership Subsidiary.  To the extent that funds are needed to cure any such exception, the Seller Parties shall cause any portion of the Closing Cash Payment being paid at Closing to be delivered to the Title Company to cure same.  If title to any Partnership Property becomes encumbered by any lis pendens or similar attachment which is being disputed in good faith by the Partnership or any Partnership Subsidiary, then the Seller Parties and Buyer shall act reasonably and in good faith to reach a mutually satisfactory resolution with respect to such Partnership Property.

5.18                        Casualty & Condemnation.  If, prior to Closing, any Partnership Property or any part thereof shall be condemned, or destroyed or damaged by fire or other casualty, or if any proceeding shall be instituted for the taking in condemnation or by eminent domain of all or a portion of any Partnership Property, the Seller Parties shall promptly so notify Buyer.  Upon Closing Buyer shall be entitled (a) in the event of a condemnation, to receive the condemnation proceeds (as and when paid if after Closing), and (b) in the event of a casualty, to receive the proceeds of insurance applicable thereto (including, if applicable, any rent loss proceeds for the post-Closing restoration period) and the Seller Parties shall give Buyer a credit (as a dollar for dollar reduction in the Purchase Price) in the amount of any deductible or coinsurance amount under the applicable Insurance Policies (but not for any uninsured loss, unless the failure to maintain such insurance constitutes a breach of the Seller Parties’ obligations under Section 2.17.  Any proceeds or awards paid to the Partnership or any Partnership Subsidiary after the date hereof in connection with a casualty or condemnation shall not be distributed to the Seller Parties, but the Partnership or applicable Partnership Subsidiary shall be entitled to use any such proceeds or awards to repair any damage done by such casualty or condemnation to the Partnership Property.  Buyer may participate in the negotiations regarding the settlement of any claim for proceeds resulting from a casualty or condemnation and Seller Parties will neither cause nor permit the Partnership or applicable  Partnership Subsidiary to settle any such claim

50

without obtaining Buyer’s prior written consent, which consent will not be unreasonably withheld, conditioned or delayed.  In addition, the Seller Parties agree that, without obtaining Buyer’s prior written consent, which consent will not be unreasonably withheld, conditioned or delayed, neither the Partnership nor any Partnership Subsidiary will make any repairs to, or otherwise restore, the Partnership Property, other than repairs required to protect the health or safety of any person or property at such Partnership Property and except as required by the terms of any Ground Lease, Partnership Space Lease or other agreement to which the Partnership or the applicable Partnership Subsidiary is a party or which is otherwise applicable to the Partnership Property. Buyer shall receive a credit against the Purchase Price for the amount of any proceeds or awards payable to Buyer as set forth above but which are instead retained by any lender (other than sums, in the case of the Mortgage Debt, which the lender is obligated, under the applicable loan documents, to apply to repair and restoration following Closing).

5.19                        Tax Appeals.  Refunds (net of the costs and expenses of the appeal) relating to the appeal or contest of real estate taxes or assessed valuations will be prorated between the Seller Parties and Buyer in a manner consistent with the proration of the real estate taxes under this Agreement for the applicable Partnership Property, subject to the rights of any tenants thereto under the applicable Partnership Space Leases.  The Seller Parties agree that no action or proceeding contesting or appealing real estate taxes or assessed valuations will be filed with respect to any of the Partnership Properties following the date of this Agreement without Buyer’s prior written consent (which shall not be unreasonably withheld, delayed or conditioned).   Without first obtaining Buyer’s written consent (which consent shall not be unreasonably withheld, delayed or conditioned), the Seller Parties will not cause or permit any Partnership Subsidiary to settle any pending appeal or contest that would affect the assessed value or real estate taxes payable with respect to any Partnership Property for any tax year for which Buyer is responsible in whole or in part pursuant to the proration of the real estate taxes under this Agreement for the applicable Partnership Property.

7.2                               Indemnification by the Seller Parties.

(a)                                 The Seller Parties (collectively, the “Seller Indemnifying Parties”) agree, subject to the other terms and conditions of this Agreement, to indemnify and defend Buyer and each of its Affiliates (including the Partnership following the Closing), officers, directors, representatives and agents (each, a “Buyer Indemnified Party”) against and hold it harmless to the extent of any and all losses, liabilities (including liabilities for Taxes), damages (including diminution in value and loss of rental income), claims, awards, judgments, costs and expenses, including, without limitation, reasonable attorneys’ fees (collectively, “Losses”) actually suffered or incurred by a Buyer Indemnified Party arising out of, in connection with or resulting from (i) the breach of any representation or warranty of the Seller Parties contained in Article II or expressly set forth in any document delivered by the Seller Parties at or in connection with the Closing pursuant to Section 6.2, (ii) any breach of any covenant or agreement of the Seller Parties contained herein or in any document delivered by the Seller Parties at or in connection with the Closing pursuant to Section 6.2, (iii) any Liabilities of the Partnership or any Partnership Subsidiary arising or accruing based on events occurring solely prior to Closing, (iv) except to the extent already included as a Current Liability in the calculation of Closing Adjusted Working Capital and without duplication, (A) any Taxes of the Partnership or the Partnership Subsidiaries for any period before the Closing, or (B) any liability of the Partnership or the Partnership Subsidiaries for the Taxes of any Person (other than the Partnership or any Partnership Subsidiary) by reason of being a transferee or successor to such Person or otherwise by operation of law prior to the Closing; or (v) any uninsured damage to, destruction or loss of any asset or property of the Partnership or the Partnership Subsidiaries in excess of $50,000; provided, however, that, in the case of either clause (i), (ii), (iii), (iv) or (v) above no such Loss shall be indemnified hereunder if and to the extent that the underlying liability or claim also gave rise to a reduction in the Purchase Consideration pursuant to Section 1.4 and provided, further, that in no event shall a Buyer Indemnified Party be entitled to indemnification under this Section 7.2 more than once for the same Loss arising from the same state of facts.

(b)                                 The indemnification obligations of the Seller Indemnifying Parties pursuant to Section 7.2(a) shall be limited as follows:

(i)                                     The Seller Indemnifying Parties shall have no obligation to provide any indemnification pursuant to Section 7.2(a) until the aggregate dollar amount of all Losses that would otherwise be indemnifiable pursuant to Section 7.2(a) exceeds Three Hundred and Fifty Thousand Dollars ($350,000.00), (the “Threshold Amount”), and then only to the extent such aggregate amount exceeds such Threshold Amount.

(ii)                                  The Seller Indemnifying Parties shall not be obligated to indemnify Buyer Indemnified Parties in the aggregate pursuant to Section 7.2(a) for any amount of otherwise indemnifiable Losses with respect to such parties in excess of Ten Million Dollars ($10,000,000.00) (the “Partnership Maximum Amount”) or from any source other than the Indemnification Escrow Amount.

(iii)                               No indemnification shall be payable to a Buyer Indemnified Party with respect to claims first asserted by a Buyer Indemnified Party pursuant to Section 7.2(a) after the date that is nine (9) months after the Closing Date (the “Indemnification Cut-Off Date”).

56

(c)                                  Payments by the Seller Indemnifying Parties pursuant to Section 7.2(a) shall be further reduced by any insurance proceeds and any indemnity, contribution or other similar payment actually received by a Buyer Indemnified Party from any third party with respect thereto.

(d)                                 Buyer, on behalf of a Buyer Indemnified Party, shall give the Seller Parties written notice (a “Claim Notice”) of any claim, assertion, event or proceeding by or in respect of a third party, or any other claim, as to which the Buyer Indemnified Party may request indemnification hereunder as soon as is practicable and in any event within thirty (30) days of the time that the Buyer Indemnified Party learns of such claim, assertion, event or proceeding; provided, however, that the failure to so notify the Seller Parties shall not affect rights to indemnification hereunder except to the extent that the Seller Indemnifying Parties are actually prejudiced by such failure.  Such Claim Notice shall contain (A) a description and the amount to the extent reasonably determinable (the “Claimed Amount”) of any Losses incurred or reasonably expected to be incurred, (B) a statement that it is entitled to indemnification under this Article VII for such Losses and a reasonable explanation of the basis therefor and (C) a demand for payment in the amount of such Losses.  Buyer, on behalf of a Buyer Indemnified Party, must also deliver a copy of such Claim Notice to the Escrow Agent simultaneously with delivery of the Claim Notice to the Seller Parties.  Upon notice to Buyer within twenty (20) days of receipt by Seller of a Claim Notice, the Seller Parties shall have the right to direct, through counsel of their own choosing, the defense or settlement of any such claim, assertion, event or proceeding by or in respect of a third party.  If the Seller Parties elect to assume the defense of any such claim, assertion, event or proceeding, the Buyer Indemnified Party may participate in such defense and in any event the Seller Parties shall keep the Buyer Indemnified Party advised as to the status of such suit or proceeding and defense thereof and shall consider in good faith recommendations made by the Buyer Indemnified Party with respect thereto, but in such case the expenses of the Buyer Indemnified Party shall be paid by the Buyer Indemnified Party.  A Buyer Indemnified Party shall provide and shall cause the Partnership to provide, as applicable, the Seller Parties and counsel with reasonable access to its records and personnel relating to any such claim, assertion, event or proceeding during normal business hours and shall otherwise cooperate with the Seller Parties in the defense or settlement thereof and the Seller Indemnifying Parties shall reimburse the Buyer Indemnified Party for all of the reasonable out of pocket expenses of such Buyer Indemnified Party in connection therewith.  Unless and until the Seller Parties elects to defend or if, after commencing or undertaking any such defense, the Seller Parties fail to prosecute or withdraws from such defense, Buyer Indemnified Party shall have the right to undertake the defense or settlement thereof, at the Seller Indemnifying Parties’ expense.  Notwithstanding the foregoing, neither the Buyer Indemnified Party, nor the Seller Indemnifying Parties or the Seller Parties, shall make any settlement or compromise of any such claim, assertion, event or proceeding without the consent of the other (which consent may not be unreasonably withheld or delayed).  Any settlement or compromise made or caused to be made by the Buyer Indemnified Party or the Seller Indemnifying Parties or the Seller Parties, as the case may be, of any such claim, assertion event, or proceeding shall also be binding upon the Seller Indemnifying Parties and the Seller Parties or the Buyer Indemnified Party, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise.

57

(e)                                  A Buyer Indemnified Party’s rights to indemnification or other remedies hereunder based upon the representations, warranties, covenants and agreements of Seller will not be affected by any investigation or knowledge of the Buyer Indemnified Party or any waiver by a Buyer Indemnified Party of any condition based on the accuracy of any representation or warranty or compliance with any covenant or agreement.  Such representations and warranties and covenants and agreements shall not be affected or deemed waived by reason of the fact that a Buyer Indemnified Party knew or should have known that any representation or warranty might be inaccurate or that the Seller Parties failed to comply with any agreement or covenant.  Any investigation by a Buyer Indemnified Party shall be for its own protection only and shall not affect or impair any right or remedy hereunder.  A Buyer Indemnified Party shall not be entitled to indemnification hereunder for any Loss arising from a breach of any representation, warranty or covenant set forth herein (and the amount of any Loss incurred in respect of such breach shall not be included in the calculation of any limitations on indemnification set forth herein) to the extent that such liability is disclosed as a current liability on the Post-Closing Balance Sheet and is expressly taken into account for purposes of determining the Closing Adjusted Working Capital and that resulting in an adjustment to the Purchase Consideration as a result thereof.

(f)                                   Within twenty (20) days after delivery of a Claim Notice by Buyer, on behalf of a Buyer Indemnified Party, the Seller Parties shall deliver to Buyer and the Escrow Agent a written response (the “Response”) in which the Seller Parties shall: (i) agree that the Buyer Indemnified Party is entitled to receive all of the Claimed Amount (in which case, the Escrow Agent promptly shall distribute to Buyer an amount of cash out of the Indemnification Escrow Amount, to the extent available, equal to the Claimed Amount), (ii) agree that the Buyer Indemnified Party is entitled to receive part, but not all, of the Claimed Amount (the “Agreed Amount”) (in which case, the Escrow Agent shall distribute to Buyer an amount of cash out of the Indemnification Escrow Amount, to the extent available, equal to the Agreed Amount) or (iii) dispute that the Buyer Indemnified Party is entitled to receive any of the Claimed Amount.  If the Seller Parties do not deliver a Response to Buyer and Escrow Agent with such 20 day period, the Seller Parties shall be deemed to have agreed that the Buyer Indemnified Party is entitled to receive all of the Claimed Amount.  If, in the Response, the Seller Parties dispute their liability for all or part of the Claimed Amount, the Seller Parties and the Buyer Indemnified Party shall follow the procedures set forth below for the resolution of such dispute (a “Dispute”).  During the fifteen (15) day period following the delivery of a Response that reflects a Dispute, the Seller Parties and the Buyer Indemnified Party shall use good faith efforts to resolve the Dispute.  If the Buyer Indemnified Party and the Seller Parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and furnished to the Escrow Agent.  The Escrow Agent shall be entitled to rely on any such memorandum as joint instructions and shall distribute the amount of cash specified in such memorandum out of the Indemnification Escrow Amount in accordance with the terms thereof.

(g)                                  Anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of Buyer or a Buyer Indemnified Party, after the consummation of the transactions contemplated hereby, to rescind this Agreement or any of the transactions contemplated hereby.

58

(h)                                 Neither the Partnership nor the Seller Indemnifying Parties shall have any liability under any provision of this Agreement for any consequential (which shall not be deemed to include loss of rents), exemplary or punitive damages or any multiple of damages (except, in each case, as damages awarded to a third party).

(i)                                     Buyer hereby acknowledges and agrees that the Indemnification Escrow Amount shall serve as the sole and exclusive remedy for satisfaction of such Seller Indemnifying Parties’ obligations pursuant to this Section 7.2.

7.3                               Indemnification by Buyer.

(a)                                 Buyer agrees, subject to the other terms and conditions of this Agreement, to indemnify the Seller Parties and each of its Affiliates, representatives and agents and the officers and directors of the Partnership prior to the Closing (each a “Seller Indemnified Party”) against and hold them harmless from all Losses actually suffered or incurred by such Seller Indemnified Party arising out of, in connection with or resulting from (i) the breach of any representation or warranty of Buyer contained herein or in any document delivered by Buyer at or in connection with the Closing pursuant to Section 6.3, or (ii) any breach of any covenant or agreement of Buyer contained herein or in any document delivered by Buyer at or in connection with the Closing pursuant to Section 6.3; provided, that in no event shall a Seller Indemnified Party be entitled to indemnification under this Section 7.3 more than once for the same Loss arising from the same state of facts.

(b)                                 The indemnification obligations of Buyer pursuant to Section 7.3(a) or otherwise in this Agreement shall not be effective until the aggregate dollar amount of all Losses that would otherwise be indemnifiable pursuant to Section 7.3(a) or otherwise in this Agreement exceeds the Threshold Amount, and then only to the extent such aggregate amount exceeds the Threshold Amount.  Buyer shall not be obligated to indemnify any Seller Indemnified Party pursuant to Section 7.3(a) or otherwise in this Agreement for any amount of indemnifiable Losses in excess of Ten Million Dollars ($10,000,000.00) (the “Buyer Maximum Amount”).  No indemnification shall be payable to a Seller Indemnified Party with respect to claims first asserted by such Seller Indemnified Party pursuant to Section 7.3(a) after the Indemnification Cut Off Date.

(c)                                  Payments by Buyer pursuant to Section 7.3(a) or otherwise in this Agreement shall be reduced by any insurance proceeds and any indemnity, contribution or other similar payment actually received by Partnership Indemnified Parties with respect thereto.

(d)                                 A Seller Indemnified Party shall give Buyer a Claim Notice of any claim, assertion, event or proceeding by or in respect of a third party, or any other claim, as to which such Seller Indemnified Party may request indemnification hereunder as soon as is practicable and in any event within thirty (30) days of the time that such Seller Indemnified Party learns of such claim, assertion, event or proceeding; provided, however, that the failure to so notify Buyer shall not affect rights to indemnification hereunder except to the extent that Buyer is actually prejudiced by such failure.  Upon notice to the Seller Indemnified Party within twenty (20) days of receipt by Seller of a Claim Notice, Buyer shall have the right to direct, through counsel of its own choosing, the defense or settlement of any such claim, assertion, event or proceeding by or

59

in respect of a third party.  If Buyer elects to assume the defense of any such claim, assertion, event or proceeding, (i) Buyer shall consult with the Seller Indemnified Party, the Seller Indemnified Party may participate in such defense, but in such case the expenses of the Seller Indemnified Party shall be paid by the Seller Indemnified Party and (ii) Buyer shall be conclusively deemed to have acknowledged that such claim, assertion, event or proceeding by or in respect of a third party is within the scope of its indemnity obligations under this Agreement.  The Seller Indemnified Party and the Seller Parties shall provide Buyer with reasonable access to its and its affiliates’ records and personnel relating to any such claim, assertion, event or proceeding during normal business hours and shall otherwise cooperate with Buyer in the defense or settlement thereof, and Buyer shall reimburse the Seller Indemnified Party for all the reasonable out of pocket expenses of such Seller Indemnified Party in connection therewith.  Unless and until Buyer elects to defend or if, after commencing or undertaking any such defense, Buyer fails to prosecute or withdraws from such defense, the Seller Indemnified Party shall have the right to undertake the defense or settlement thereof, at Buyer’s expense.  Notwithstanding the foregoing, neither the Seller Indemnified Party nor Buyer shall make any settlement or compromise of any such claim, assertion, event or proceeding without the consent of the other (which consent may not be unreasonably withheld or delayed).  Any settlement or compromise made or caused to be made by the Seller Indemnified Party or Buyer, as the case may be, of any such claim, assertion, event or proceeding shall also be binding upon Buyer or the Seller Indemnified Party, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise.

(e)                                  Anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of the Seller Parties, after the consummation of the transactions contemplated by this Agreement, to rescind this Agreement or any of the transactions contemplated hereby.

(f)                                   Buyer shall not have any liability under any provision of this Agreement for any consequential, exemplary or punitive damages or any multiple of damages.

7.4                               Treatment of Indemnity Payments.  All payments made by the Seller Parties or Buyer, as the case may be, to or for the benefit of the other parties pursuant to this Article VII shall be treated as adjustments to the Purchase Consideration for tax purposes, and such agreed treatment shall govern for purposes of this Agreement.

7.5                               Remedies Exclusive.

(a)                                 Buyer hereby acknowledges and agrees that prior to the Closing, Buyer shall have no right or remedy to take any action in respect of, and the Seller Parties shall have no liability to Buyer in respect of, any breach by the Seller Parties of any of their respective representations or warranties contained herein or a failure to comply with any of their covenants, conditions or agreements contained herein, except (i) to terminate this Agreement pursuant to Section 8.1 hereof, or (ii) seek specific performance or injunctive relief.

(b)                                 The Seller Parties hereby acknowledges and agrees that prior to the Closing, the Seller Parties shall have no right or remedy to take any action in respect of, and

60

(c)                                  From and after the Closing, the rights of the parties to indemnification relating to this Agreement or the transactions contemplated hereby shall be strictly limited to those contained in this Article VII or explicitly set forth elsewhere in this Agreement, such indemnification rights shall be the sole and exclusive remedies of the parties and the Seller Parties subsequent to the Closing Date with respect to any matter in any way relating to this Agreement or arising in connection herewith other than specific performance and injunctive relief.  To the maximum extent permitted by law, the parties hereby waive all other rights and remedies with respect to any matter in any way relating to this Agreement or arising in connection herewith, whether under any laws (including any right or remedy under the Resource Conservation and Recovery Act, 42 U.S.C. Section 6901 et seq., the Comprehensive Environmental Response Compensation and Liability Act, 42 U.S.C. Section 9602 et seq., or any other Environmental Law), at common law or otherwise.  Except as provided in this Agreement, no claim, action or remedy shall be brought or maintained by any party against any other party, and no recourse shall be brought or granted against any of them, by virtue of or based upon any alleged misstatement or omission respecting an inaccuracy in or breach of any of the representations, warranties or covenants of any of the parties hereto set forth or contained in this Agreement, except to the extent that the same shall have been the result of fraud in the inducement by any party hereto.  Notwithstanding anything in this Agreement, in no event shall any limit or restriction on any rights or remedies set forth in this Agreement limit or restrict the rights or remedies of any party for fraud by any other party hereto.

ARTICLE VIII - TERMINATION, AMENDMENT AND WAIVER

8.1                               Termination.  This Agreement may be terminated at any time prior to Closing:

(a)                                 by mutual written consent of Buyer and of the Seller Parties;

(b)                                 by Buyer at any time prior to the Closing;

(c)                                  by either Buyer or the Seller Parties, if any judgment, injunction, order, decree, ruling or action by any Governmental Entity of competent authority preventing the consummation of the Partnership Interest Purchase shall have become final and non-appealable, provided, however, that the party terminating this Agreement pursuant to this Section 8.1(c) shall have used its reasonable best efforts to have such judgment, injunction, order, decree, ruling or action vacated;

(d)                                 by either Buyer or the Seller Parties, if the Partnership Interest Purchase shall not have been consummated before October 16, 2013 (subject to extension by mutual agreement of Buyer and the Seller Parties, such agreement in case of an extension to October 23, 2013 or a sooner date shall not be unreasonably withheld or delayed by either party, the “Termination Date”); provided, however, that a party may not terminate pursuant to this clause (d) if the terminating party shall have breached in any material respect its obligations

61

under this Agreement or is in breach of any representation or warranty contained herein in any manner that shall have been the principal cause of the inability of the parties to consummate the Partnership Interest Purchase or resulted in the failure of the Closing to occur by the Termination date;

(e)                                  by Buyer, upon a breach of any representation, warranty, covenant, obligation or agreement on the part of the Seller Parties set forth in this Agreement, or if any representation or warranty of the Seller Parties shall have become untrue, in either case, such that the conditions set forth in Section 6.2(a) or Section 6.2(b), as the case may be, would be incapable of being satisfied by the Termination Date; or

(f)                                   by the Seller Parties, upon a breach of any representation, warranty, covenant obligation or agreement on the part of Buyer set forth in this Agreement (including without limitation failure to have sufficient financing when all other conditions in Article VI have been satisfied or waived or to the extent applicable susceptible of being satisfied), or if any representation or warranty of Buyer shall become untrue, in either case, such that the conditions set forth in Section 6.3(a) or Section 6.3(b), as the case may be, would be incapable of being satisfied by the Termination Date.

8.2                               Effect of Termination.

(a)                                 In the event of termination of this Agreement by either the Seller Parties or Buyer pursuant to Section 8.1, this Agreement shall immediately become void and have no effect, without any liability or obligation on Buyer or the Seller Parties, except (i) if the Agreement is terminated (A) pursuant to Section 8.1(d) (by either party) at a time when both (x) conditions to Closing set forth in Section 6.3 (excluding Section 6.3(c)) have been satisfied or waived (or would be satisfied if the Closing were held) and (y) the conditions to Closing set forth in Section 6.2  have not been satisfied or waived, or (B) pursuant to Section 8.1(c) or 8.1(e), then the Buyer shall be entitled to receive the Signing Deposit (including interest or other income therefrom) from the Escrow Agent, and in all other cases the Signing Deposit will be delivered to the Seller Parties by the Escrow Agent, (ii) the obligations in Section 5.2, this Section 8.2 and Article IX shall survive any termination of this Agreement and (iii) for fraud.  The payment of the Signing Deposit to the Seller Parties pursuant to the foregoing sentence above is a condition to the Seller Parties’ willingness to enter into this Agreement and represents liquidated damages intended to reimburse the Seller Parties for incurring the damages, costs and expenses related to entering into this Agreement, is not a penalty and is in lieu of any other rights or remedies under this Agreement.

(b)                                 Notwithstanding anything to the contrary set forth in Section 8.2(a), unless Cabot Industrial Value Fund III, Inc. (the “Fund Subsidiary REIT”) shall have received a tax opinion of counsel or a ruling from the IRS to the effect that the Fund Subsidiary REIT’s receipt of its share of the Signing Deposit will be treated as qualifying income with respect to the Fund Subsidiary REIT for purposes of Section 856(c)(2) and 856(c)(3) of the Code or shall be excluded from income for such purposes (a “Positive Tax Opinion or Ruling”), the aggregate amount of the Signing Bonus deemed paid to the Seller Parties shall be limited to the maximum amount (“Allowed Signing Deposit”) that can be paid without causing the Fund Subsidiary REIT’s receipt of its pro rata share of such funds to cause the Fund Subsidiary REIT to fail to

62

meet the requirements of Sections 856(c)(2) and (3) of the Code, determined as if the payment of such amount did not constitute qualifying income for such purposes, as determined by independent accountants to the Partnership or the Fund Subsidiary REIT, which determination shall be provided to Buyer.  In the event that the Signing Deposit exceeds the Allowed Signing Deposit, then such excess amount (the “Escrowed Deposit”) shall be delivered to the Escrow Agent in accordance with the Escrow Agreement in a separate interest-bearing, segregated account for the account of Buyer.  The Seller Parties shall pay all costs associated with obtaining any tax opinion of counsel or ruling from the IRS described above.  The Escrowed Deposit shall be fully disbursed (and therefore any unpaid portion of  the Signing Deposit shall be paid to the Seller Parties pro rata) upon receipt of a Positive Tax Opinion or Ruling. To the extent not previously paid, upon any determination by independent accountants to the Partnership or the Fund Subsidiary REIT that any additional amount of the Signing Deposit may be disbursed (to the Seller Parties pro rata) without causing the Fund Subsidiary REIT to fail to meet the requirements of Sections 856(c)(2) and 856(c)(3) of the Code, determined as if the payment of such amount did not constitute qualifying income for such purposes, the determination of such independent accountants shall be provided to the Escrow Agent and such additional amount shall be disbursed (and therefore such portion of the Signing Deposit shall be paid to the Seller Parties pro rata).  At the end of the second calendar year beginning after the Closing Date (or earlier if directed by the Partnership or the Fund Subsidiary REIT), any remainder of the Escrowed Deposit (together with interest thereon) then being held by the Escrow Agent shall be disbursed to Buyer and, in the event that the Signing Deposit has not by then been paid in full, such unpaid portion of the Signing Deposit shall be deemed forgiven.  The Seller Parties shall bear any and all expenses associated with the escrow of the Escrowed Deposit.  Each of the Seller Parties is hereby granted the power of attorney on behalf of Buyer to execute, acknowledge, swear to and deliver all such documents required in connection with the foregoing escrow account, such power to be irrevocable and coupled with an interest.

8.3                               Amendment.  This Agreement may be amended by the parties in writing by action of Buyer and the Seller Parties at any time prior to Closing; provided, however, that there shall be no amendment to Sections 8.3, 8.4, 9.5, 9.6 and 9.7 (or any provision of this Agreement to the extent an amendment of such provision would modify the substance of Sections 8.3, 8.4, 9.5, 9.6 and 9.7) in a manner that would be adverse to the Financing Parties without the prior written consent of the Financing Parties.

8.4                               Extension; Waiver.  At any time prior to the Closing, Buyer, on one hand, and the Seller Parties, on the other hand, may (a) extend the time for the performance of any of the obligations or other acts of the other party, or (b) waive any inaccuracies in the representations and warranties of the other party contained in this Agreement or in any document delivered pursuant to this Agreement or waive compliance with any of the agreements or conditions of the other party contained in this Agreement, except that there shall be no waiver to Sections 8.3, 8.4, 9.5, 9.6 and 9.7 (or any provision of this Agreement to the extent a waiver of such provision would modify the substance of Sections 8.3, 8.4, 9.5, 9.6 and 9.7) in a manner that would be adverse to the Financing Parties without the prior written consent of the Financing Parties.  Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.  Waiver of any term or condition of this Agreement by a party shall not be construed as a waiver of any subsequent breach or waiver of the same term or condition by such party, or a waiver of any other term or condition of this

63

Agreement by such party.  The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

ARTICLE IX - GENERAL PROVISIONS

9.1                               Nonsurvival of Representations and Warranties.  Except as expressly provided for in Article VII of this Agreement, none of the representations and warranties in this Agreement or in any instrument delivered pursuant to this Agreement shall survive the Closing.  This Section 9.1 shall not limit any covenant or agreement of the parties that by its terms contemplates performance after the Closing.

9.2                               Notices.  All notices, requests, claims, demands and other communications under this Agreement shall be in writing and shall be delivered personally, sent by overnight courier (providing proof of delivery) to the parties or sent by facsimile (providing confirmation of transmission) at the following addresses or facsimile numbers (or at such other address or telecopy number for a party as shall be specified by like notice):

9.6                               Governing Law; Consent to Jurisdiction.  THIS AGREEMENT WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF DELAWARE REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICT OF LAWS.  EACH OF BUYER AND THE SELLER PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY CONSENTS TO SUBMIT TO THE SOLE AND EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF DELAWARE AND OF THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE (THE “DELAWARE COURTS”) FOR ANY LITIGATION ARISING OUT OF OR RELATING TO

66

THIS AGREEMENT, OR THE NEGOTIATION, VALIDITY OR PERFORMANCE OF THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED HEREBY (AND AGREES NOT TO COMMENCE ANY LITIGATION RELATING THERETO EXCEPT IN SUCH COURTS), WAIVES AN OBJECTION TO THE LAYING OF VENUE OF ANY SUCH LITIGATION IN THE DELAWARE COURTS AND AGREES NOT TO PLEAD OR CLAIM IN ANY DELAWARE COURT THAT SUCH LITIGATION BROUGHT THEREIN HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  EACH OF THE PARTIES HERETO AGREES (A) TO THE EXTENT SUCH PARTY IS NOT OTHERWISE SUBJECT TO SERVICE OF PROCESS IN THE STATE OF DELAWARE, TO APPOINT AND MAINTAIN AN AGENT IN THE STATE OF DELAWARE AS SUCH PARTY’S AGENT FOR ACCEPTANCE OF LEGAL PROCESS, AND (B) THAT SERVICE OF PROCESS MAY ALSO BE MADE ON SUCH PARTY BY PREPAID CERTIFIED MAIL WITH A PROOF OF MAILING RECEIPT VALIDATED BY THE UNITED STATES POSTAL SERVICE CONSTITUTING EVIDENCE OF VALID SERVICE.  SERVICE MADE PURSUANT TO (A) OR (B) ABOVE SHALL HAVE THE SAME LEGAL FORCE AND EFFECT AS IF SERVED UPON SUCH PARTY PERSONALLY WITHIN THE STATE OF DELAWARE.  NOTWITHSTANDING THE FOREGOING, NO PARTY HERETO, NOR ANY OF ITS AFFILIATES, WILL BRING OR SUPPORT THE BRINGING OF, ANY CLAIM, WHETHER AT LAW OR IN EQUITY, WHETHER IN CONTRACT OR IN TORT OR OTHERWISE, AGAINST ANY FINANCING PARTY IN ANY WAY RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, INCLUDING ANY DISPUTE ARISING OUT OF OR RELATING IN ANY WAY TO THE FINANCING, THE FINANCING AGREEMENTS OR THE FINANCING LETTERS OR THE PERFORMANCE THEREOF, ANYWHERE OTHER THAN IN (I) ANY NEW YORK STATE COURT SITTING IN THE COUNTY OF NEW YORK OR (II) THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK.

9.7                               Waiver of Jury Trial.  TO THE EXTENT PERMITTED BY LAW, THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING (INCLUDING ANY COUNTERCLAIM) RELATING TO THIS AGREEMENT INCLUDING, BUT NOT LIMITED TO, ANY DISPUTE ARISING OUT OF OR RELATING IN ANY WAY TO THE FINANCING, THE FINANCING AGREEMENTS OR THE FINANCING LETTERS OR THE PERFORMANCE THEREOF.

(a)                                 Except as otherwise provided in Section 7.2, any and all remedies expressly conferred upon a party to this Agreement shall be cumulative with, and not exclusive of, any other remedy contained in this Agreement, at law or in equity and the exercise by a party to this Agreement of any one remedy shall not preclude the exercise by it of any other remedy.

67

(b)                                 The parties to this Agreement agree that irreparable damage, for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed by the Seller Parties in accordance with their specific terms or were otherwise breached.  It is accordingly agreed that prior to the valid termination of this Agreement in accordance with Article VIII, Buyer will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement (without, in each case, the posting of a bond or other security) in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

(c)                                  The parties hereto agree that irreparable damage would occur in the event that the parties’ obligations under Section 5.2 (Confidentiality) or Section 5.8 (Financing) are not performed by one or more of the parties hereto in accordance with the terms hereof or were otherwise breached and that Buyer and the Seller Parties shall be entitled to specific performance of the terms and provisions of such Sections or an injunction to prevent any breach of such sections, in addition to any other remedy at law or equity.

9.10                        Severability.  Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction.  If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

9.11                        Expenses.  Except as otherwise specified in this Agreement, all costs and expenses, including, without limitation, fees and disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses, whether or not the Closing shall have occurred.

(a)                                 Title Insurance and Surveys.  Without limiting the foregoing, Buyer shall pay all fees, costs and other expenses to obtain any of the following items to the extent desired by Buyer or required by any lender of the Mortgage Debt or any other lender to Buyer or any of its affiliates: updated title searches, reports or title insurance commitments; the Owner’s Title Policies and any policies or date-down endorsements or other endorsements to existing title owner’s or lender’s title insurance policies of any lenders on the Mortgage Debt; updated surveys or amendments or endorsements to existing surveys, and similar items with respect to title and survey matters affecting the Partnership Properties.

(b)                                 Transfer Taxes and Recording Fees.  In the event that any real estate recording fees or Transfer Taxes become payable as a result of the Partnership Interest Purchase, the Seller Parties and Buyer will each pay one-half of any such recording fees or Transfer Taxes.  Each party shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any taxes or fees described in this Section 9.9(b).  “Transfer Taxes” shall mean any and all taxes, fees, charges or costs imposed by state, county or local authorities on the direct or indirect transfer of title to or beneficial interest in real property

68

regardless of whether referred to as a tax or otherwise, including, without limitation, any taxes caused by any transfer of controlling interests in a Partnership Subsidiary or Affiliate following the original vesting of title of any Partnership Property in such Partnership Subsidiary or Affiliate.

(c)                                  Loan Assumption Fees.  At or prior to the Closing, Buyer will pay Loan Assumption Feeds and the lender legal fees and other reimbursements as provided in Section 5.10.

(d)                                 Escrow Fees.  The Seller Parties and Buyer will each pay one-half of any escrow closing fees in connection with the closing of the transactions contemplated by this Agreement.

This DEPOSIT ESCROW AGREEMENT (this “Agreement”) is dated as of the 31st day of July, 2013, by and among Liberty Property Limited Partnership, a Pennsylvania limited partnership (“Buyer”), Cabot Industrial Value Fund III Manager, Limited Partnership, a Massachusetts limited partnership (the “LP Seller”), Cabot Industrial Value Fund III, Inc., a Maryland corporation (“General Partner” and together with the LP Seller, the “Escrow Participants”), and U.S. Bank National Association, a national banking association (the “Escrow Agent”), as escrow agent.  The Buyer, LP Seller and General Partner are sometimes referred to herein, collectively, as the “Interested Parties.”

WHEREAS, the Buyer, LP Seller and General Partner have entered into a Partnership Interest Transfer Agreement dated July 31, 2013 (the “Purchase Agreement”) pursuant to which LP Seller and General Partner will, subject to the terms and conditions therein, sell all of their limited partnership interests and general partnership interests in Cabot Industrial Value Fund III Operating Partnership, L.P., a Delaware Limited Partnership (the “Partnership”) to Buyer (the “Partnership Interest Sale”);

WHEREAS, pursuant to Section 1.5 of the Purchase Agreement, Buyer shall deposit $25,000,000.00 in cash into escrow to be retained by the Escrow Agent until the earlier to occur of (i) the consummation of the Partnership Interest Sale, and (ii) the termination of the Purchase Agreement, in accordance with the procedures set forth herein; and

WHEREAS, the Interested Parties wish to engage the Escrow Agent to act, and the Escrow Agent is willing to act, as escrow agent hereunder and, in that capacity, to hold, administer and distribute the amounts deposited in escrow hereunder in accordance with, and subject to, the terms of this Agreement;

NOW THEREFORE, for valuable consideration, the receipt whereof is hereby acknowledged, the parties hereto agree as follows:

Section 1.                                          Definitions.

“Business Day” means each day, other than a Saturday, Sunday or other day on which banks in Hartford, Connecticut are required by law to close.

Section 2.                                          Deposit of Escrow Funds.

Within one (1) Business Day after the execution and delivery of this Agreement, Buyer shall deposit with the Escrow Agent in immediately available funds the amount of $25,000,000 (the “Escrow Funds”, and together with any investment income or proceeds received by the Escrow Agent from the investment thereof from time to time pursuant to Section 4 below, collectively, the “Escrow Property”) and the Escrow Agent agrees to hold the Escrow Property in an account established with the Escrow Agent (the “Escrow Account”), and to administer the Escrow Property in accordance with the terms of this Agreement.

A-2

Section 3.                                          Claims and Payment; Release from Escrow.

(a)         General.  Subject to Section 3(b) and Section 6 below, Escrow Agent shall, at any time, distribute all or such part of the Escrow Property as directed by and in accordance with the terms of (i) a Joint Written Direction (as defined below), or (ii) a final, non-appealable written order of a court of competent jurisdiction, a copy of which is delivered by Buyer or the Escrow Participants to Escrow Agent at least two (2) business days prior to such distribution.  Escrow Agent shall consider any such written order submitted pursuant to clause (ii) of the preceding sentence to be a final, non-appealable written order or decision of a court of competent jurisdiction, and shall not be under any obligation to make further inquiry.  As used in this Agreement, a “Joint Written Direction” shall mean a written direction executed by each of Buyer and the Escrow Participants and directing Escrow Agent to disburse all or a portion of the Escrow Property or to take or refrain from taking an action pursuant to this Agreement.  Any Joint Written Direction directing the disbursement of all or any portion of the Escrow Property shall contain wiring instructions or an address to which a check shall be sent.

(b)         Termination Notice. Each of the Buyer, on the one hand, and the Escrow Participants, on the other hand, agree that, in the event that such party (a “Terminating Party”) delivers a notice to the other party/parties terminating the Purchase Agreement pursuant to Section 8.1 of the Purchase Agreement, the Terminating Party will simultaneously deliver a copy of such notice to the Escrow Agent, which notice shall specify the provision of the Purchase Agreement pursuant to which the Terminating Party is terminating the Purchase Agreement.  If the non-Terminating Party delivers a written notice to the Terminating Party and the Escrow Agent objecting to the provision upon which the Purchase Agreement was terminated and specifying with reasonable particularity its basis therefor which is received by the Escrow Agent within 10 business days (an “Objection Notice”) of the Escrow Agent’s receipt of the termination notice, then the Escrow Property shall be retained in the Escrow Account and distributed by Escrow Agent only in accordance with the terms of Section 3(a) above and Section 6.  If the non-Terminating Party does not timely deliver an Objection Notice, then if, as specified in the termination notice, (i) the Purchase Agreement is terminated (A) pursuant to Section 8.1(d) of the Purchase Agreement at a time when both (x) conditions to the closing of the Partnership Interest Sale set forth in Section 6.3 of the Purchase Agreement (excluding Section 6.3(c)) have been satisfied or waived (or would be satisfied if the closing of the Partnership Interest Sale were held) and (y) the conditions to closing of the Partnership Interest Sale set forth in Section 6.2 of the Purchase Agreement have not been satisfied or waived or (B) pursuant to Section 8.1(c) or 8.1(e), then Escrow Agent shall release to the Buyer, within two (2) business days after the end of such 10 business day period, the Escrow Property and (ii) the Purchase Agreement is terminated in any other manner, Escrow Agent shall release to the Escrow Participants, subject to Section 6, within two (2) business days after the end of such 10 business day period, the Escrow Property, on a pro rata basis in accordance with their respective percentage interests set forth on Exhibit C.

(c)          Termination Date. Each of the Buyer, on the one hand, and the Escrow Participants, on the other hand, agree that, in the event that no party delivers a notice terminating the Purchase Agreement as set forth in Section 3.1(c) above prior to October 16, 2013 (subject to extension pursuant to the terms of the Purchase Agreement, the “Termination Date”), subject to Section 6, Escrow Agent shall release to the Escrow Participants, within two (2) business days thereafter,

A-3

the Escrow Property, on a pro rata basis in accordance with their respective percentage interests set forth on Exhibit C; provided, however, that the Termination Date may be extended by mutual agreement of the Interested Parties and delivery of joint written notice to the Escrow Agent of such extension.  Buyer and the Escrow Participants agree that any notice extending the Termination Date pursuant to the Purchase Agreement will be delivered to the Escrow Agent concurrently.

Section 4.                                          Investment of Funds.

(a)         General.  If the Escrow Agent shall have received specific joint written investment instruction from Buyer, LP Seller and General Partner (which shall include instruction as to term to maturity, if applicable), on a timely basis, the Escrow Agent shall invest the Escrow Property in Eligible Investments, pursuant to and as directed in such instruction.

(b)         “Eligible Investments.” shall mean (i) obligations issued or guaranteed by the United States of America or any agency or instrumentality thereof (provided that the full faith and credit of the United States is pledged in support thereof); (ii) shares of a money market fund that is subject to regulation under the Investment Company Act of 1940, 15 U.S.C. 80a-1 et seq., and complies with the requirements of Rule 2a-7 thereof, (iii) deposit accounts or certificates of deposit of any domestic commercial bank having capital and surplus in excess of $500,000,000, which, in the case of certificates of deposit, are negotiable and have a ready secondary market; (iv) investment in the Escrow Agent’s “Money Market Deposit Account” (“MMDA”), as described in Annex A hereto.  If otherwise qualified, obligations of the Escrow Agent or any of its affiliates shall qualify as Eligible Investments.  Notwithstanding the foregoing, Eligible Investments shall be limited to those instruments readily obtainable and routinely offered by the Escrow Agent’s Corporate Trust Services.

(c)          Escrow Agent Not Responsible For Investment Decisions.  Absent its timely receipt of such specific joint written investment instruction from Buyer, LP Seller and General Partner, the Escrow Agent shall have no obligation or duty to invest (or otherwise pay interest on) the Escrow Property; provided, however, that in the event the Escrow Agent shall not have received such written investment instruction, the Escrow Agent shall be authorized to invest any of the Escrow Property in the Escrow Agent’s MMDA until such investment instruction is received.  All earnings received from the investment of the Escrow Property shall be credited to, and shall become a part of, the Escrow Property (and any losses on such investments shall be debited to the Escrow Account).  Subject to Section 7(b) of this Agreement, the Escrow Agent shall have no liability for any investment losses, including without limitation any market loss on any investment liquidated prior to maturity in order to make a payment required hereunder.

(d)         Transaction Confirmations.  The parties hereto acknowledge that, to the extent regulations of the Comptroller of the Currency, or other applicable regulatory entity, grant the parties the right to receive individual confirmations of security transactions at no additional cost, as they occur, the parties specifically waive receipt of such confirmations to the extent permitted by law.  The Escrow Agent will furnish the parties hereto with periodic cash transaction statements that include detail for all investment transactions made by the Escrow Agent hereunder.

A-4

Section 5.                                          Tax Reporting.

(a)                                 The Interested Parties agree that, unless otherwise specified in this Agreement, any investment income earned (or proceeds received), prior to the disbursement of the Escrow Property, during a calendar year period from the investment of the Escrow Property, shall be treated consistently with the terms of Section 1.5(c) of the Purchase Agreement and shall be reported on an annual basis by the Escrow Agent (and the Escrow Agent agrees to so report such income) on the appropriate Form 1099 (or Form 1042-S), as required pursuant to the Internal Revenue Code  of 1986 (“Code”) and the regulations thereunder as having been earned by the Buyer.

(b)                                 The Interested Parties are responsible for making an affirmative communication to the Escrow Agent if the securities being exchanged, redeemed, or sold are classified as “Covered Securities” or “Non-Covered Securities” under the Internal Revenue Service Cost Basis Reporting regulations.  If such securities are classified as “Covered Securities”, the parties are jointly responsible for providing the required information to the Escrow Agent for sending accurate and complete Form 1099-B information to the Escrow Participants’.  The required information shall be each Escrow Participants’ date of acquisition and each Escrow Participants cost basis of the applicable security, and any such other information that the Escrow Agent may request to be in compliance with the IRS 1099-B reporting regulations under the Internal Revenue Code.  Notwithstanding the foregoing, the parties view the securities being exchanged, redeemed or sold pursuant to the Purchase Agreement as “Non-Covered Securities.  The information shall be provided timely to the Escrow Agent so it can meet its obligations to send Form 1099-B information to the Escrow Participants and the IRS by the applicable reporting deadlines.

(c)                                  General Partner is responsible for providing guidance to the Escrow Agent on the appropriate allocation of the cost basis to each Escrow Participant’s distribution.  The Escrow Agent shall rely upon such guidance to perform the required tax reporting for distributions made from the Escrow Accounts.

(d)                                 Certification of Taxpayer Identification Number.  Each of the Interested Parties hereto agrees to provide the Escrow Agent with a certified tax identification number by signing and returning a Form W-9 (or Form W-8 BEN, in case of non-U.S. persons) to the Escrow Agent upon the execution and delivery of this Agreement.  The Interested Parties understand that, in the event their tax identification numbers are not certified to the Escrow Agent, the Internal Revenue Code, as amended from time to time, may require withholding of a portion of any interest or other income earned on the investment of the Escrow Property.  The Interested Parties also agree to provide the Escrow Agent with all documentation necessary for the Escrow Agent to comply with the Foreign Account Tax Compliance Act.  Each of the Interested Parties agrees to instruct the Escrow Agent in writing with respect to the Escrow Agent’s responsibility for withholding and other taxes, assessments or other governmental charges, and to instruct the Escrow Agent with respect to any certifications and governmental reporting that may be required under any laws or regulations that may be applicable in connection with its acting as Escrow Agent under this Agreement.

Section 6.                                          Certain Conditions.  Notwithstanding anything to the contrary in this Agreement, unless the General Partner shall have received a tax opinion of counsel or a ruling from the IRS to the effect that the General Partner’s receipt of its share of the Escrow Property will be treated as qualifying income with respect to the General Partner for purposes of Section 856(c)(2) and 856(c)(3) of the Code or shall be excluded from income for such purposes (a “Positive Tax Opinion or Ruling”), the aggregate amount of the Escrow Property to be paid or distributed to the Escrow Participants pursuant to this Agreement shall be limited to the maximum amount (“Allowed Escrow Property”) that can be paid without causing the General Partner’s receipt of its pro rata share of such funds to cause the General Partner to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, determined as if the payment of such amount did not constitute qualifying income for such purposes, as determined by independent accountants to the Escrow Participants, which determination shall be provided to Buyer and to the Escrow Agent at least two (2) Business Days prior to the applicable date on which the Escrow Agent is required to make a distribution of Escrow Property.  In the event that the Escrow Property exceeds the Allowed Escrow Property, then such excess amount (the “Escrowed Deposit”) shall be retained by the Escrow Agent in a separate interest-bearing, segregated account for the account of Buyer.  The Escrow Participants shall pay all costs associated with obtaining any tax opinion of counsel or ruling from the IRS described above.  The Escrowed Deposit shall be fully disbursed (and therefore any unpaid portion of  the Escrow Property shall be paid to the Escrow Participants pro rata) upon receipt of a Positive Tax Opinion or Ruling. To the extent not previously paid, upon any determination by independent accountants to the Escrow Participants that any additional amount of the Escrow Property may be disbursed (to the Escrow Participants pro rata) without causing the General Partner to fail to meet the requirements of Sections 856(c)(2) and 856(c)(3) of the Code, determined as if the payment of such amount did not constitute qualifying income for such purposes, the determination of such independent accountants shall be provided to the Escrow Agent and such additional amount shall be disbursed at least two (2) Business Days prior to the applicable date on which the Escrow Agent is required to make a distribution of Escrow Property (and therefore such portion of the Escrow Property shall be paid to the Escrow Participants pro rata).  At the end of the second calendar year beginning after the Closing Date (as defined in the Purchase Agreement) (or earlier if directed by the General Partner or the LP Seller), any remainder of the Escrowed Deposit (together with interest thereon) then being held by the Escrow Agent shall be disbursed to Buyer and, in the event that the Escrow Property has not by then been paid in full, such unpaid portion of the Escrow Property shall be deemed forgiven.  The Escrow Participants shall bear any and all expenses associated with the escrow of the Escrowed Deposit.  The Escrow Participants are hereby granted the power of attorney on behalf of Buyer to execute, acknowledge, swear to and deliver all such documents required in connection with the foregoing escrow account, such power to be irrevocable and coupled with an interest. The parties intend for this Section 6 to be interpreted and applied in a manner consistent with Section 8.2(b) of the Purchase Agreement and to the extent of any inconsistencies between the two provisions, the terms of the Purchase Agreement shall control.

Section 7.                                          Concerning the Escrow Agent.

(a)                                 Each Interested Party acknowledges and agrees that the Escrow Agent (i) shall not be responsible for any of the agreements referred to or described herein (including without limitation the Purchase Agreement), or for determining or compelling compliance therewith, and shall not otherwise be bound thereby, (ii) shall be obligated only for the performance of such

(b)                                 The Escrow Agent shall not be liable to anyone for any action taken or omitted to be taken by it hereunder except in the case of the Escrow Agent’s gross negligence or willful misconduct.  In no event shall the Escrow Agent be liable for indirect, punitive, special or consequential damage or loss (including but not limited to lost profits) whatsoever, even if the Escrow Agent has been informed of the likelihood of such loss or damage and regardless of the form of action.

(c)                                  The Escrow Agent shall have no more or less responsibility or liability on account of any action or omission of any book-entry depository, securities intermediary or other subescrow agent employed by the Escrow Agent than any such book-entry depository, securities intermediary or other subescrow agent has to the Escrow Agent, except to the extent that such action or omission of any book-entry depository, securities intermediary or other subescrow agent was caused by the Escrow Agent’s own gross negligence or willful misconduct in breach of this Agreement.

(d)                                 The Escrow Agent is hereby authorized, in making or disposing of any investment permitted by this Agreement, to deal with itself (in its individual capacity) or with any one or more of its affiliates, whether it or such affiliate is acting as a subagent of the Escrow Agent or for any third person or dealing as principal for its own account.

(e)                                  Notwithstanding any term appearing in this Agreement to the contrary, in no instance shall the Escrow Agent be required or obligated to distribute any Escrow Property (or take other action that may be called for hereunder to be taken by the Escrow Agent) sooner than two (2) Business Days after (i) it has received the applicable documents required under this Agreement in good form, or (ii) passage of the applicable time period (or both, as applicable under the terms of this Agreement), as the case may be.

(f)                                   Unless and except to the extent otherwise expressly set forth herein, all deposits and payments hereunder, or pursuant to the terms hereof (including without limitation all payments to the Escrow Agent pursuant to Section 8, shall be in U.S. dollars.

It is understood and agreed that, should any dispute arise with respect to the delivery, ownership, right of possession, and/or disposition of the Escrow Property, or should any claim be made upon the Escrow Agent or the Escrow Property by a third party, the Escrow Agent upon receipt of notice of such dispute or claim is authorized and shall be entitled (at its sole option and election) to retain in its possession without liability to anyone, all or any of the Escrow Property until such dispute shall have been settled either by the mutual written agreement of the parties involved or by a final order, decree or judgment of a court in the United States of America, the time for perfection of an appeal of such order, decree or judgment having expired.  The Escrow Agent may, but shall be under no duty whatsoever to, institute or defend any legal proceedings which relate to the Escrow Property.
