Except as otherwise provided in this Agreement, all funds deposited into the Escrow by Purchaser shall be immediately deposited by Escrow Agent into an interest bearing account, subject to the control of Escrow Agent in a bank or savings and loan association, or such other institution approved by Purchaser and Seller, or such other investment as may be approved by Purchaser and Seller; provided, however, that such funds must be readily available as necessary to comply with the terms of this Agreement and the Escrow Agreement, and for the Escrow to close within the time specified in Section 5.1 of this Agreement. Except as may be otherwise specifically provided herein, interest on amounts placed by Escrow Agent in any such investments or interest bearing accounts shall accrue to the benefit of Purchaser, and Purchaser shall promptly provide to Escrow Agent Purchaser’s Tax Identification Number.

TITLE AND PROPERTY CONDITION

4.1 Title to the Real Property .

4.1.1 Acceptance of Title as of the Effective Date . The parties acknowledge and agree that the Title Company has made available to Purchaser commitments for title insurance (collectively, the “ Title Commitments ”) addressing the status of title to each Property as of a date prior to the Effective Date, including (to the extent available) copies of Liens and Encumbrances that are indicated as Property-specific exceptions to title in such Title Commitments. Purchaser has had the opportunity to review and approve the Title Commitments. Each of the Title Commitments is identified on Exhibit P . The parties acknowledge and agree that the Purchaser has received for each Property a survey that complies with the Survey Standards. Each of the surveys, including all revisions required by Purchaser, is identified on Exhibit Q (such surveys are referred to herein as the “ Surveys ”). Purchaser hereby acknowledges and agrees that, except as set forth in the first sentence of Section 4.1.2 , all of the Liens and Encumbrances shown on the Title Commitments and the Surveys are Permitted Exceptions, and that the Sellers shall not be obligated to Cure any of such Liens or Encumbrances. The Sellers shall not be obligated to Cure any Liens or Encumbrances arising after the effective date of any Title Commitment or Survey except as provided in Section 4.1.2 and Section 4.2.3 .

4.1.2 Liens Arising After the Effective Date . Each Seller, with respect to its Property or Properties, agrees to Cure, prior to or at Closing, (i) all Voluntary Liens; and (ii) the Involuntary Liens, if any, listed on Exhibit S . If a Seller or Purchaser becomes aware that an Involuntary Lien has arisen after the effective date of the Title Commitment for the Property affected by such Involuntary Lien, such Seller or Purchaser, as applicable, shall promptly give notice to the other of such Involuntary Lien. If the cost to Discharge such Involuntary Lien, together with the cost to Discharge all other Involuntary Liens (excluding Liens caused by Tenants) of which the Purchaser or any Seller has received notice pursuant to this Section 4.1.2 after the date hereof and prior to Closing (each, a “ New Lien ”), does not exceed $1,000,000, then such Seller shall be obligated to Cure such New Lien prior to or at Closing, at such Seller’s sole cost and expense, and such New Lien shall not be a Permitted Exception. If the aggregate cost to Discharge all New Liens exceeds $1,000,000, then the Sellers shall have the option but not the obligation to Cure, at their sole cost and expense, each New Lien for which the cost to Discharge (together with the cost to

Discharge all other New Liens) exceeds $1,000,000. Sellers shall notify Purchaser of their election with respect to each New Lien for which the cost to Discharge (together with the cost to Discharge all other New Liens) exceeds $1,000,000, within five (5) Business Days after such Seller either sends or receives notice of such New Lien pursuant to the second sentence of this Section 4.1.2 . If the Sellers do not make such election in writing within such five (5) Business Days, the Sellers shall be deemed to have elected not to Cure such New Lien. If none of the Sellers has elected to Cure a New Lien for which the cost to Discharge (together with the cost to Discharge all other New Liens) exceeds $1,000,000, Purchaser shall be entitled to terminate this Agreement by written notice to Sellers, in which case the Earnest Money Deposit shall be returned to Purchaser, this Agreement shall terminate and neither party shall have any obligation to the other party hereunder except for obligations that expressly survive termination of this Agreement. If any Seller fails to Cure a New Lien by Closing that such Seller was obligated to Cure or elected to Cure pursuant to this Section 4.1.2 , Seller shall be in default under this Agreement and Purchaser shall have all rights under Section 9.2 hereof, provided however, Purchaser may elect to proceed to Closing and Purchaser shall receive a credit equal to the aggregate cost to Discharge all New Liens that any Seller was obligated to or elected to Cure, but failed to Cure at or before Closing. Any New Liens for which Purchaser receives a credit at Closing pursuant to the preceding sentence shall be Permitted Exceptions.

4.1.3 Encumbrances Arising After the Effective Date . The Sellers agree not to create or subject any Property to any Encumbrance after the Effective Date (other than Encumbrances that are Cured at or prior to Closing), without the prior written consent of the Purchaser. Any New Encumbrance that a Seller creates or subjects a Property to after the Effective Date and prior to Closing is referred to herein as a “ Seller-Created Encumbrance ”). Seller-Created Encumbrances are not Permitted Exceptions. If after the Effective Date either a Seller or Purchaser first becomes aware of an Encumbrance (other than a Seller-Created Encumbrance) that was not disclosed by any of the Title Commitments or revisions thereof prior to the Effective Date (a “ New Encumbrance ”), Purchaser or such Seller, as applicable, shall promptly give notice to the other of such New Encumbrance. If Purchaser objects to such New Encumbrance, Purchaser shall give notice to such Seller of its objection within ten (10) Business Days after discovering such New Encumbrance or receiving notice of such New Encumbrance pursuant to the preceding sentence. If Purchaser does not timely object to it, such New Encumbrance shall be a Permitted Exception. If Purchaser timely objects to such New Encumbrance, such Seller shall give notice to Purchaser, within ten (10) days of Purchaser’s objection notice (the “ Seller Response Period ”), as to whether such Seller agrees to attempt to Cure such New Encumbrance. If a Seller elects in writing to attempt to Cure a New Encumbrance to which Purchaser timely objects pursuant to this Section 4.1.3 , such Seller shall use commercially reasonable efforts to Cure such New Encumbrance at or before Closing (provided however, the Closing may be extended for such reasonable time as may be necessary to Cure such New Encumbrance, not to exceed an additional sixty (60) days), and such New Encumbrance shall not be a Permitted Exception. If such Seller declines to attempt to Cure such New Encumbrance or fails to respond to Purchaser’s notice of the same within the Seller Response Period, then Purchaser shall be entitled to terminate this Agreement by written notice to Seller given not more than five (5) days after expiration of the Seller Response Period. If Purchaser does not terminate this Agreement by written notice to Seller within such five (5) day period, then Purchaser shall be deemed to have elected to proceed with Closing, Purchaser shall not have any right to terminate this Agreement on account of such New Encumbrance, and such New Encumbrance shall be a Permitted Exception. If the Sellers fail to Cure all Seller-Created Encumbrances prior to or at

Closing, then Purchaser shall have the remedies, if any, set forth in Article 9 as a result of such failure. If Purchaser terminates this Agreement pursuant to this Section 4.1.3 , the Earnest Money Deposit shall be returned to Purchaser, this Agreement shall terminate and neither party shall have any obligation to the other party hereunder except for obligations that expressly survive termination of this Agreement.

4.2 Inspection .

4.2.1 Prior to the date hereof, each of the Sellers made available to Purchaser certain information, documents, agreements and reports in each Seller’s possession or control relating to the Properties (collectively, the “ Due Diligence Materials ”) without representation or warranty of any kind or nature, whether express or implied, except as provided in this Agreement. The parties acknowledge that Purchaser has had the opportunity to review and inspect the Due Diligence Materials and all of the Properties prior to the date hereof. By executing this Agreement, Purchaser acknowledges that it has completed its inspections and studies of all of the Properties and it has no remaining rights to object to any due diligence matters, and is agreeing to proceed in accordance with the terms hereof (including without limitation, the terms of Section 4.3 below). Notwithstanding such prior inspections, the Sellers shall cooperate and provide Purchaser with reasonable and continuing access to the Real Property included in each Property upon commercially reasonable Notice to the Sellers for the purpose of Purchaser’s inspections, investigations, appraisals, tenant interviews, engineering studies, soil test, environmental studies and underwriting analyses (provided, however, that Purchaser shall not perform any invasive testing of any Real Property without the Sellers’ prior written consent in each instance, which may be granted or withheld in the Sellers’ sole and absolute discretion, provided, Seller shall not unreasonably withhold its consent to invasive testing that is recommended by preliminary inspection reports). Neither Purchaser nor any of its employees, agents or representatives shall contact or otherwise discuss this transaction and /or the operation of the Properties with any on-site employees of the Properties without such Seller’s consent; provided, however, that Purchaser may meet with any Property’s asset manager upon commercially reasonable Notice to the Property’s Seller but, if required by such Seller, only in the presence of such Seller’s representative. Each Seller shall have the right to have a representative of such Seller present during all inspections, examinations or interviews concerning such Seller’s Real Property by Purchaser.

4.2.2 Prior to any entry by Purchaser or any of Purchaser’s designees onto any Property, Purchaser shall: (i) if Purchaser does not then have such a policy in force, procure a policy of commercial general liability insurance, issued by an insurer reasonably satisfactory to the Sellers, covering all of Purchaser’s activities at such Property, with a single limit of liability (per occurrence and aggregate) of not less than $2,000,000.00; and (ii) deliver to Sellers a Certificate of Insurance, evidencing that such insurance is in force and effect, and evidencing that the Seller that owns such Property has been named as an additional insured thereunder with respect to any of Purchaser’s activities. Such insurance shall be written on an “occurrence” basis, and shall be maintained in force until the earlier of (x) the termination of this Agreement and the conclusion of all of Purchaser’s inspections, or (y) the Closing Date.

4.2.3 Purchaser, at all times, will conduct all inspections and reviews in compliance with all Legal Requirements, and in a manner so as to not cause damage, loss, cost or expense to any Seller, any Property or Tenants of any Property, and without unreasonably interfering with or

disturbing any Tenants or employees at the Properties. Prior to Closing, the results of or any other information acquired pursuant to Purchaser’s inspections shall be subject to the terms and conditions of Section 12.16 below. Purchaser will promptly restore any damage to any Property caused by Purchaser’s inspection to its condition immediately preceding such inspections and examinations and will keep the Properties free and clear of any mechanic’s liens or materialmen’s liens in connection with such inspections and examinations.

4.2.4 Purchaser shall notify Seller in writing on or before September 30, 2013 as to which of the Contracts Purchaser desires to have assigned to Purchaser at Closing. The Contracts that Purchaser elects to assume in such notice (other than any Contracts that are not assignable), together with the Construction Management Agreement, the Work Agreements and the Contracts designated as “Miscellaneous Agreements” on Exhibit C are referred to in this Agreement as the “ Assumed Contracts .” Except for Multi-Property Contracts, each of the Assumed Contracts shall be included in the Assignment of Contracts described in Section 5.2.4 . Notwithstanding the immediately preceding sentence, any fee charged by a service provider to transfer an Assumed Contract shall be borne by the Sellers. Sellers shall terminate any Contracts that are not Assumed Contracts, effective as of the Closing Date, and any costs or fees charged by the service provider in connection with such termination shall be borne by the Sellers; provided, however, if a Contract that is not an Assumed Contract provides for a termination that does not end prior to the Closing Date, then, provided that a Seller has delivered notice terminating such Contract on or before October 15, 2013, such Contract shall be an Assumed Contract. Sellers shall have no obligation to assign or terminate any Service Contract that is not assignable or terminable by its terms. Purchaser shall assume all of the Assumed Contracts on the Closing Date. Purchaser acknowledges and agrees that the Multi-Property Contracts, if any, will be assigned only in part, with the portion of each Multi-Property Contract that does not relate to any of the Properties being retained by the Seller. Each Multi-Property Contract shall be omitted from the Assignment of Contracts and the foregoing partial assignment with respect to such Multi-Property Contract shall be evidenced by one or more separate assignment documents in the form required by the other party to such Multi-Property Contract and reasonably satisfactory to the parties. For purposes of this Agreement, “ Multi-Property Contract ” means an Assumed Contract pursuant to which services are rendered to one or more properties that are not included in the Properties. Contracts pursuant to which services are rendered to one or more properties that are not included in the Properties are designated as such on Exhibit C . Notwithstanding anything to the contrary, if any Seller has engaged a manager to manage such Seller’s Property, such Seller shall cause such management agreement to be terminated at or prior to Closing.

4.2.5 The cost of the inspections and tests undertaken pursuant to this Section 4.2 shall be borne solely by Purchaser.

4.2.6 Purchaser covenants and agrees that, until the Closing Date, all information and materials disclosed and/or delivered to it by the Sellers, or Sellers’ agents, employees and representatives (including without limitation, the Due Diligence Materials), are confidential and proprietary information, and that Purchaser shall hold the same in accordance with the terms and conditions of Section 12.16 below. Purchaser also agrees that, in the event the transactions contemplated in this Agreement are not consummated as provided herein, Purchaser shall promptly return to the Sellers or destroy (and confirm in a notice to Sellers that Purchaser has returned or destroyed) all such information and documentation, and all copies thereof.

4.2.7 Except as expressly provided herein, none of the Sellers makes any representations or warranties as to the truth, accuracy or completeness of any materials, data or other information, if any, supplied to Purchaser in connection with Purchaser’s inspection of any of the Properties (e.g., that such materials are complete, accurate or the final version thereof, or that all such materials are in any Seller’s possession). Except for Purchaser’s reliance on any representation and warranties expressly provided herein, it is the parties’ express understanding and agreement that any such materials are to be provided only for Purchaser’s convenience in making its own examination and determination as to whether it wishes to purchase the Properties, and, in doing so, Purchaser shall rely exclusively on its own independent investigation and evaluation of every aspect of each Property and not on any materials supplied by the Sellers. Except for Purchaser’s reliance on any representation and warranties expressly provided herein with respect to any such materials, Purchaser expressly disclaims any intent to rely on any such materials provided to it by the Sellers in connection with its inspection and agrees that it shall rely solely on its own independently developed or verified information.

4.2.8 The obligations of Purchaser under this Section 4.2 shall survive Closing or the termination of this Agreement indefinitely.

4.3 Condition of the Property .

CLOSING

5.1 Closing Date . The “ Closing Date ” for purposes of this Agreement shall be November 12, 2013, or such earlier date as may be agreed upon, in writing, by the Sellers and Purchaser; subject, however, to the Sellers’ and Purchaser’s rights to extend the Closing Date as set forth in herein.

5.1.1 Notwithstanding anything to the contrary contained in this Agreement, (a) the Closing Date for the Woodholme MOB Property shall be the first Wednesday, Thursday or Friday immediately following the date set forth in the first sentence of Section 5.1 above, and (b) if the Closing Date for the Woodholme MOB Property is postponed for any reason, the Closing Date for the Woodholme MOB Property shall not occur on a Monday or a Tuesday; if the postponed Closing Date for the Woodholme MOB Property falls on a Monday or a Tuesday, then the postponed Closing Date for the Woodholme MOB Property shall be extended to the immediately following Wednesday. Sellers and Purchaser will conduct a “pre-closing” commencing on the second (2nd) Business Day preceding the scheduled Closing Date for the Woodholme MOB Property (the “ Pre-Closing Date ”). If this Agreement has not been terminated as to the Woodholme MOB Property in accordance with its terms prior to the Pre-Closing Date, and if Sellers and Purchaser have each determined that all conditions precedent to such party’s obligations to close have been satisfied (or waived in accordance with this Agreement) as of the Pre-Closing Date as to the Woodholme MOB Property (except as set forth below):

(a) By no later than 2:00 p.m. (eastern time) on the Pre-Closing Date: (x) the Woodholme MOB Seller shall have delivered to the Escrow Agent all documents and funds required to be executed and delivered by the Woodholme MOB Seller pursuant to Section 5.2 of this Agreement (collectively, the “ Seller Deliveries ”), and (y) Purchaser shall have delivered to the Escrow Agent the Allocated Amount of the Woodholme MOB Property in immediately available funds (reduced or increased by such amounts as are required to take into account any prorations, credits, costs or other adjustments to be made at Closing under this Agreement with respect to the Woodholme MOB Property), together with all documents required to be executed and delivered by Purchaser pursuant to Section 5.3 of this Agreement (collectively, the “ Purchaser Deliveries ”).

(b) The delivery of the Seller Deliveries to the Escrow Agent shall constitute the Woodholme MOB Seller’s agreement that, solely as they relate to the Woodholme MOB Property, all conditions precedent to such Seller’s obligation to closing have been satisfied or waived in accordance with this Agreement, other than the receipt by such Seller of the Purchaser Deliveries relating to the Woodholme MOB Property on the Closing Date and the satisfaction of the condition set forth in Section 5.1.2 of this Agreement.

(c) The delivery of the Purchaser Deliveries to the Escrow Agent shall constitute Purchaser’s agreement that, solely as they relate to the Woodholme MOB Property, all conditions precedent to Purchaser’s obligation to Closing have been

satisfied or waived in accordance with this Agreement, other than the receipt by Purchaser of the Seller Deliveries relating to the Woodholme MOB Property on the Closing Date and the satisfaction of the condition set forth in Section 5.1.2 of this Agreement.

(d) Purchaser agrees that it will do, execute, acknowledge and deliver, or will cause to be done, executed, acknowledged and delivered, all such further acts, documents and instruments as may reasonably be required in order for Seller to defease the Existing Woodholme MOB Financing.

5.1.2 Notwithstanding any other provision in this Agreement (i) if the Existing Woodholme MOB Financing cannot be discharged or defeased on the scheduled Closing Date for the Woodholme MOB Property, or (ii) any of the closing conditions set forth in Section 8.1 or Section 8.2 have not been fulfilled or satisfied on the Pre-Closing Date, Seller shall have the right to postpone the Closing Date solely with respect to the Woodholme MOB Property, for such period of time as may be necessary to discharge or defease the Existing Woodholme MOB Financing or otherwise fulfill or satisfy such closing conditions, but in no event shall Seller have the right to postpone the Closing Date pursuant to this Section 5.1.2 for more than sixty (60) days (the “ Defeasance Extension Period ”). Sellers shall provide notice to Purchaser exercising an extension, if any, pursuant to this Section 5.1.2 at the earliest possible time. Notwithstanding any provision of this Agreement to the contrary, Purchaser acknowledges and agrees that, so long as the Woodholme MOB Seller uses commercially reasonable efforts to consummate the defeasance of the Existing Woodholme MOB Financing, the Woodholme MOB Seller shall not be in default solely because such defeasance fails to occur. It shall be a condition to the Woodholme MOB Seller’s obligation to Sell the Woodholme MOB Property, and to the Purchaser’s obligation to buy the Woodholme MOB Property, that the defeasance of the Woodholme MOB Existing Financing shall have occurred or shall occur simultaneously with such purchase and sale. Notwithstanding anything to the contrary in this Agreement, if the defeasance of the Existing Woodholme MOB Financing has not occurred as of the date that is sixty-five (65) days from the initially-scheduled Closing Date for the Woodholme MOB Property set forth in Section 5.1.1 above, either Sellers or Purchaser may terminate this Agreement solely as to the Woodholme MOB Property (unless such defeasance has failed to occur because of a breach of this Agreement by the party desiring to terminate pursuant to this sentence), and thereupon Purchaser shall receive the Woodholme MOB Property’s Allocated Share of the Earnest Money Deposit (to the extent the same then remains in escrow).

5.2 Action Prior to the Closing Date by the Sellers . Subject to Section 5.1.1 , the Sellers agree that on or before 1:00 p.m. on the Closing Date the Sellers will deposit with Escrow Agent the following items and instruments (executed and acknowledged, if appropriate):

5.5 Prorations .

5.5.1 Taxes . At or prior to Closing Sellers shall pay for each Property all amounts due and owing as of the Closing Date with respect to real estate and personal property general and special taxes and assessments. With respect to each Property, all non-delinquent real estate and personal property general and special taxes and assessments for such Property for the current assessment year of the applicable taxing authority in which the Closing Date occurs shall be prorated as of the Closing Date. If the exact amount of taxes is not known at Closing, the proration will be based on an amount equal to 105% of the prior assessment year’s taxes and shall be adjusted once actual figures become available after Closing, as part of the Final Closing Adjustment. It is understood that any supplemental property tax bill issued as a result of the sale of any Property pursuant to the provisions of this Agreement shall be borne by Purchaser, provided however, Seller shall be responsible for any roll-back taxes, if applicable. Notwithstanding anything to the contrary in this Agreement, (i) each Seller shall retain all right, title and interest in and to any and all property tax (both real property and personal property) refunds and claims for refunds with respect to its Properties for any period prior to the Closing Date, and (ii) each Seller is responsible for all taxes due and payable for its Property prior to the Closing Date. Each Seller shall have the right to continue and control any contest of any taxes or assessments for its Property or Properties due and payable during all tax years prior to the tax year in which Closing occurs. If Seller has appealed

or contested any real property tax assessment which affects taxes for the year of Closing and/or thereafter, Seller shall notify Purchaser of same and at Closing, Seller shall assign such appeal or contest to Purchaser and Purchaser shall have the right to prosecute the same. If Purchaser receives any refund which is applicable to periods prior to the year in which Closing occurs, Purchaser shall promptly pay such portion (net of any tax consultants’ fees) to Seller, unless such amounts are payable to any Tenant pursuant to any Leases assigned to Purchaser at Closing. Purchaser shall have the right to control any contest of any taxes or assessments for the Properties due and payable during the current tax year in which Closing occurs, if any, and all tax years thereafter. Seller and Purchaser shall each reasonably cooperate with the other in connection with such contests. Sellers shall be responsible for all sales, use and other transfer taxes imposed in connection with the sale and transfer of the Personal Property and the Intangible Property.

5.5.2 Utility Service .

If such billings or meter readings as of the Business Day preceding the Closing Date are obtained, adjustments for any costs, expenses, charges or fees shown thereon shall be made in accordance with such billings or meter readings. If such billings or meter readings as of the Business Day preceding the Closing Date are not available for a utility service, the charges therefor shall be adjusted at the Closing on the basis of the per diem charges for the most recent prior period for which bills were issued and shall be further adjusted at the Final Closing Adjustment on the basis of the actual bills for the period in which the Closing takes place. Each Property’s Seller shall receive a credit at Closing for the Utility Deposits, if any, that are transferred or made available to Purchaser and that are held by applicable utility companies for the account of such Seller in respect of services provided to such Seller’s Property or Properties. Purchaser shall arrange for placing all utility services and bills in its own name as of the Closing Date.

5.5.3 Security Deposits. 5.5 Security Deposits Purchaser shall not receive a credit at Closing for any of the Security Deposits, but at Closing each Seller shall pay to Purchaser in cash an amount equal to all cash Security Deposits being held by such Seller, such Seller’s managing agent or any other Person under the Leases at such Seller’s Properties. The Sellers shall be entitled to retain all Security Deposits or other such credits due Tenants for which Purchaser receives credit or payment, and for which the Sellers are charged, pursuant to this Section 5.5.3 . Sellers agree not to apply any Security Deposits held as of the Effective Date under Leases on account of arrearages existing as of the Effective Date. If any security deposits are in the form of a letter of credit, Seller shall assign (to the extent such letter of credit is assignable without the consent of its issuer) its interest in the letter of credit to Purchaser and deliver the original letter of credit to Purchaser at Closing. All costs to assign such letter of credit shall, unless payable by the Tenant, be borne by Purchaser; provided, however, that if the costs to assign all of such letters of credit, in the aggregate, exceed $5,000, Seller shall be responsible for the amount by which such aggregate costs exceed $5,000. If Seller is unable to provide for the transfer of Seller’s interest in any letter of credit at or prior to Closing, then (a) Seller shall, at Purchaser’s request prior to Closing, request from the issuer of such letter of credit the required documentation in order to allow Seller and Purchaser to prepare, execute and submit such documentation for transfer of such letter of credit at Closing or as soon as possible after Closing; (b) Seller shall continue to cooperate with Purchaser in arranging for the assignment to Purchaser of the beneficiary’s interest under such letter of credit (or the re-issuance

to Purchaser of such letter of credit) promptly following the Closing, and (c) if requested by Purchaser upon the default by a tenant under its Lease, Seller shall present the letter of credit, together with a draw request prepared by Purchaser, for payment and Seller shall pay the proceeds to Purchaser and Purchaser shall indemnify Seller for, and shall defend Seller and hold Seller harmless against, any and all claims, losses, liabilities, costs or expenses (including reasonable attorneys’ fees and disbursements) actually incurred by Seller which were directly caused in connection such presentment. This Section 5.3.3 obligation shall survive Closing, and Section 9.8 is not applicable to such indemnification obligation.

5.5.4 Accounts Payable and Operating Expenses . All operating expenses shall be prorated between the Sellers and Purchaser as of the Closing Date on an accrual basis, based on the actual number of days in the month during which the Closing Date occurs for monthly expenses, and based on a 365 day year for annual expenses. The Sellers shall be responsible for all operating expenses attributable to the period before the Closing Date and Purchaser shall be responsible for all operating expenses attributable to the period on and after the Closing Date.

5.5.5 Miscellaneous Permits and Taxes . Except as covered by the terms of Section 5.5.1 above, with respect to each Property, all water and sewer charges and taxes (other than ad valorem property taxes) shall be prorated as of the Closing Date. Each Property’s Seller will be credited for that portion of taxes and fees paid by such Seller allocable to the period after the Closing Date.

5.5.6 Assumed Contracts . With respect to each Property, all payments made or to be made under Assumed Contracts (to the extent such payments accrued or will accrue over a period that straddles the Closing Date), and all receipts actually received under Assumed Contracts, as applicable, shall be prorated between Purchaser and such Property’s Seller as of the Closing Date. Purchaser shall receive a credit for all accrued and unpaid amounts thereunder and such Seller shall receive a credit for all prepayments and refundable deposits thereunder that are expressly assigned to Purchaser and acknowledged by the contractor in writing.

5.5.7 Leasing Commissions, Tenant Improvements and Rental Abatements.

(a) Each Seller shall pay prior to the Closing Date, or shall give Purchaser a credit at Closing, for all Leasing Commissions, TI Obligations, free rent, abatements and other concessions (including without limitation, lease buyout costs (i.e., the obligation, if any, of a Seller to pay all or a portion of a Tenant’s or a prospective Tenant’s remaining rent under such Tenant’s or prospective Tenant’s lease at an unrelated property) moving costs, design costs and club membership allowances) (all of the foregoing, collectively, “ Lease Expenses ”) (but excluding Pending Turnkey TI Obligations (as defined below), which shall be governed by Section 5.5.7(d) below) to which such Seller has committed under the terms of a Lease or a Lease modification, extension or renewal entered into prior to the Effective Date (excluding, however, Lease Expenses of the kind referred to in Section 5.5.7(b)(ii) ).

(b) Purchaser shall pay for (and shall not receive a credit at Closing for) (i) Lease Expenses due in connection with a Lease or a Lease modification, extension or renewal that is executed on or after the Effective Date with Purchaser’s prior written approval, and (ii) Lease Expenses that become due with respect to the exercise by a Tenant on or after the Effective Date of an extension, expansion or renewal option to which such Tenant was entitled under the terms of its Lease as of the Effective Date.

(c) Effective as of the Closing Date, Purchaser shall honor and assume all covenants and obligations to be performed by each Seller as landlord under the Leases first arising on or after the Closing Date, including any Lease Expenses. Purchaser shall reimburse the Sellers at Closing for any payments made prior to Closing by any Seller toward Lease Expenses that Purchaser is obligated to pay under this Section 5.5.7 .

(d) Special Escrow for Turnkey Projects. Each Property that, as of the Effective Date, has a Lease with a “turnkey” TI Obligation is listed on Exhibit D-2 . For each such turnkey TI Obligation that has not been completed prior to Closing (all such incomplete turnkey TI Obligations being referred to as “ Pending Turnkey TI Obligations ”), such Property’s Seller shall deposit with Escrow Agent at Closing funds equal to 110% of the then remaining, unpaid costs to complete the tenant improvement work (as determined by Sellers and reasonably approved by Purchaser), less any amounts that Tenant is obligated to fund or reimburse “landlord” for such work under the applicable Lease. Such amount (the “ Turnkey Escrow ”) will be held by Escrow Agent and disbursed in accordance with an Escrow Agreement (a “ Turnkey Escrow Agreement ”) in the form attached hereto as Exhibit V . For the avoidance of doubt, this Section 5.5.7(d) applies only to turnkey TI Obligations arising under Leases or Lease modifications, extensions or renewals entered into prior to the Effective Date, and does not apply to any other turnkey TI Obligations, which Purchaser shall be responsible for under Section 5.5.7(b) and the first sentence of Section 5.5.7(c) . From and after the Effective Date, Sellers shall not commence any “turnkey” TI Obligations without the prior written consent of Purchaser, except as required under the Assumed Contracts, under Leases in existence as of the Effective Date or under Leases approved by Purchaser after the Effective Date, and except pursuant to Work Agreements approved by Purchaser. The Work Agreements with respect to any Pending Turnkey TI Obligation (including but not limited to the construction management contract (the “ Construction Management Agreement ”) with Cassidy Turley (the “ Construction Manager ”)) have been provided to Purchaser for review, are listed on Exhibit C and shall be Assumed Contracts (subject to the right of Purchaser to be reimbursed by the applicable Seller for tenant improvement costs related to such Work Agreements pursuant to the applicable Turnkey Escrow Agreement).

5.5.8 Other Income . With respect to each Property, all income not specifically addressed in this Section 5.5 and derived by such Property’s Seller from such Property, to the extent such income accrues before the Closing Date, shall be paid to such Seller. All income not specifically addressed in this Section 5.5 and derived by such Seller from such Property accruing or relating to the period on and after the Closing Date shall be paid to Purchaser.

5.5.9 Other Expenses . With respect to each Property, all expenses and obligations not otherwise specified in this Section 5.5 , incurred in the ownership or operation of such Property and constituting an assumed liability or arising under any agreement or other matter included in the Property to be conveyed hereunder shall be prorated between such Property’s Seller and Purchaser as of the Closing Date.

5.5.10 Rent . Rent shall be prorated at the Closing in accordance with the following provisions:

(a) Basic Rent . Subject to Section 5.5.10(c) , Basic Rent shall be prorated between each Seller and Purchaser as of the Closing Date based on the actual number of days in the month during which the Closing Date occurs. Each Seller shall be entitled to all Basic Rent which accrues before the Closing Date and Purchaser shall be entitled to all Basic Rent which accrues on and after the Closing Date.

(b) Additional Rent . Subject to Section 5.5.10(c) , monthly or other payments made by Tenants in advance based upon projected or estimated Additional Rent shall be prorated between each Seller and Purchaser as of the Closing Date based on the actual Additional Rent collected as of the Closing and the actual number of days in the monthly or other period for which the advance payment is made. Such proration shall be made separately for each Tenant which is obligated to pay Additional Rent on the basis of the fiscal year set forth in the Tenant’s Lease for the determination and payment of Additional Rent. Each payment of Additional Rent that is prorated pursuant to this Section 5.5.10(b) , and the applicable Tenant’s payments of Additional Rent made prior to or after such prorated payment for the same calendar year or other fiscal period during which a year-end reconciliation of Additional Rent is required by the applicable Lease, shall be adjusted as part of the Final Closing Adjustment as provided below in Section 5.5.11 .

(c) Delinquent Rent . Delinquent Rent (including delinquent Additional Rent) shall not be prorated at Closing and shall be paid by Purchaser to the applicable Seller if, as and when actually collected by Purchaser after the Closing, it being understood and agreed that Purchaser shall use commercially reasonable efforts to collect Delinquent Rent on behalf of each Seller. Rents received by Purchaser after Closing, but prior to the next month’s Rent payment date from Tenants who have not previously paid their Rent for the month of Closing, shall be applied to the Rent due for the month of Closing and shall be prorated between Purchaser and Seller as if such Rent were received prior to the Closing Date. Purchaser and Sellers hereby agree that (a) each Seller and its agents may not initiate litigation to collect Delinquent Rent without the Purchaser’s prior written consent; and (b) if Purchaser does not

consent in writing to a Seller’s commencing litigation to collect Delinquent Rent against a Tenant within five (5) Business Days after the date on which such Seller gave Purchaser written notice requesting Purchaser’s consent to such litigation, Purchaser shall make a cash payment to such Seller, not later than ten (10) Business Days after such written request by such Seller, in an amount equal to seventy-five percent (75%) of the amount of the applicable Tenant’s receivables that are delinquent for thirty (30) days or less (and upon receipt of such payment such Seller shall be deemed to have waived any right to commence litigation against the applicable Tenant for its Delinquent Rent). No Seller may commence litigation that would terminate a Tenant’s Lease or affect a Tenant’s right to occupy the premises leased under its Lease. Rent collected by Purchaser after the Closing Date shall be applied first to Rent currently due, then Delinquent Rent due Purchaser, and then Delinquent Rent due Seller, if any. Unpaid and Delinquent Rent collected by Seller or Purchaser after the date of Closing shall be delivered as follows: (i) if Seller collects any unpaid or Delinquent Rent for the Property, Seller shall, within fifteen (15) days after the receipt thereof, deliver to Purchaser any such rent which Purchaser is entitled to hereunder relating to the date of Closing and any period thereafter, and (ii) if Purchaser collects any unpaid or delinquent rent from the Property, Purchaser shall, within fifteen (15) days after the receipt thereof, deliver to Seller any such rent which Seller is entitled to hereunder relating to the period prior to the date of Closing.

(d) Notwithstanding the foregoing, if Purchaser would otherwise be entitled to a credit for Rent prorations pursuant to this Section 5.5.10, then, at Sellers’ election, Sellers shall make a cash payment to Purchaser at Closing in lieu of such credit, and, to the extent of such cash payment, Purchaser shall not be entitled to any credit for Rent prorations pursuant to this Section 5.5.10 .

5.5.11 Final Closing Adjustment . No later than May 31 of the calendar year following the calendar year in which the Closing occurs with respect to each Property, the Sellers and Purchaser shall make a final adjustment to the prorations made pursuant to this Section 5 (the “ Final Closing Adjustment ”) with respect to such Property. The Final Closing Adjustment shall be made in the following manner:

(a) General . All adjustments or prorations which could not be determined at the Closing because of the lack of actual statements, bills or invoices for the current period, the year-end reconciliation of Additional Rent, or any other reason, shall be made as a part of the Final Closing Adjustment. Any net adjustment in favor of Purchaser shall be paid in cash by the Sellers to Purchaser no later than thirty (30) days after the Final Closing Adjustment. Any net adjustment in favor of the Sellers shall be paid in cash by Purchaser to the Sellers no later than thirty (30) days after the Final Closing Adjustment. Without limiting the foregoing, the parties shall correct any manifest error in the prorations and adjustments made at Closing promptly after such error is discovered.

(b) Additional Rent Adjustment . Promptly after Purchaser completes the reconciliation of Additional Rent under each Tenant’s Lease for the calendar year in which the Closing Date occurred (the “ Tenant’s Fiscal Year ”), Sellers and Purchaser shall adjust the Closing Date proration of Additional Rent pursuant to Section 5.5.10(b) above, as follows:

(i) The parties shall determine the aggregate amount of expenses that were incurred by Purchaser or by a Seller, that are reimbursable by such Tenant through Additional Rent under such Tenant’s Lease, and that are attributable to the Tenant’s Fiscal Year (“ Reimbursable Expenses ”).

(ii) The parties shall determine (A) the total amount of Additional Rent actually received (by either Purchaser or a Seller) from the Tenant in respect of the Tenant’s Fiscal Year (including payments received pursuant to invoices for Additional Rent deficits determined as a result of year-end reconciliations) (collectively, the “ Additional Rent Received ”), (B) what portion of the Additional Rent Received was received by Purchaser and (C) what portion of the Additional Rent Received was received by a Seller.

(iii) The parties shall determine the “ Purchaser’s Share ,” which shall be a percentage equal to (x) the portion of Reimbursable Expenses that was actually incurred by Purchaser after Closing (excluding those for which Purchaser received a credit at Closing), divided by (y) the total amount of the Reimbursable Expenses. As used herein, the term “ Seller’s Share ” means the result (expressed as a percentage) of subtracting the Purchaser’s Share from 100%.

(iv) If the Reimbursable Expenses exceed the Additional Rent Received, then Purchaser shall make a payment to Seller or Seller shall make a payment to Purchaser, so that Seller shall have received the Seller’s Share of the Additional Rent Received and Purchaser shall have received the Purchaser’s Share of Additional Rent Received.

(v) If the Additional Rent Received equals the Reimbursable Expenses, then Purchaser shall make a payment to Seller or Seller shall make a payment to Purchaser, so that Seller shall have received the Seller’s Share of the Additional Rent Received and Purchaser shall have received the Purchaser’s Share of Additional Rent Received.

(vi) If the Additional Rent Received exceeds the Reimbursable Expenses, then (a) Seller or Purchaser (or both, as applicable) shall return to the applicable Tenant(s) the amount of such excess, and (b) Purchaser shall make a payment to Seller or Seller shall make a payment to Purchaser, so that Seller shall have received the Seller’s Share of the Additional Rent Received (net of the payment referred to in the preceding clause (a)) and Purchaser shall have received the Purchaser’s Share of Additional Rent Received (net of the payment referred to in the preceding clause (a)).

(c) No Further Adjustments . Except for: (i) additional or supplemental real estate taxes, real estate tax credits or rebates, or other adjustments to real estate taxes due to back assessments, corrections to previous tax bills or real estate tax

appeals or contests, (ii) any item of Additional Rent which may be contested by a Tenant or (iii) manifest errors, the Final Closing Adjustment shall be conclusive and binding upon the Sellers and Purchaser, and the Sellers and Purchaser hereby waive any right to contest after the Final Closing Adjustment any prorations, apportionments or adjustments to be made pursuant to this Section 5 . Sellers shall fully cooperate with Purchaser in order to complete the Final Closing Adjustment and Sellers shall provide Purchaser with any information reasonably requested by Purchaser or as may be required under the Leases to perform final calculations, adjustments and reconciliations.

5.5.12 General Provisions . Except as otherwise expressly provided in this Agreement, all apportionments and adjustments shall be made in accordance with generally accepted accounting principles. The computation of the adjustments shall be jointly prepared by the Sellers and Purchaser. In the event any prorations or apportionments made under this Section 5.5 shall prove to be incorrect for any reason, then any party shall be entitled to an adjustment to correct the same in accordance with the remaining terms of Section 5.5.11 . For proration purposes, the day that falls on the Closing Date shall be charged to Purchaser.

5.5.13 Survival . Until June 30 of the calendar year after the calendar year in which the Closing of each Property occurs, (a) the provisions of this Section 5.5 shall survive as they relate to such Property (but thereafter shall expire), (b) Sellers shall indemnify Purchaser for any and all amounts and obligations which are the responsibility of Sellers under this Section 5.5 and such obligation shall not be subject to the limitations of Section 9.4 and Section 9.5 hereof, and (c) Purchaser shall indemnify Sellers for any and all amounts and obligations which are the responsibility of Purchaser under this Section 5.5 , and Sections 9.7 and 9.8 shall not be applicable to such indemnification obligation (or to the underlying obligations under this Section 5.5 to which such indemnification obligation relates). Notwithstanding the foregoing, if, on or prior to June 30 of the calendar year after the calendar year in which the Closing of each Property occurs, Sellers or Purchaser provide the other party with notice of a specific Claim for a reimbursement or adjusting payment pursuant to this Section 5.5 with respect to such Property, and if such reimbursement or adjusting payment is due at the time such notice is given, then the provisions of this Section 5.5 shall continue to survive, solely with respect to such Claim.

5.6 Closing Costs . With respect to each Property, Purchaser shall bear the cost of (i) the title searches and preparation of the Title Commitments prepared by the Title Company, and the premium for Purchaser’s title policies and any and all endorsements requested by Purchaser or its lender; (ii) the Survey for each Property; (iii) one-half (1/2) of the documentary transfer taxes and the recording fees for the Deeds, subject to a maximum amount of $2,258,976 for such taxes and fees; (iv) one-half (1/2) of all escrow and closing fees relating to the sale of such Property; (v) all escrow and closing fees relating to Purchaser’s financing; (vi) any mortgage taxes or recording fees for any mortgages securing Purchaser’s financing; and (vii) one-half (1/2) of the fees and charges of third parties in connection with the Surveys. With respect to each Property, such Property’s Seller shall bear the cost of (i) any commission due to Broker (as defined in Article X ); (ii) the greater of (x) one-half (1/2) of the documentary transfer taxes and the recording fee for the Deeds and (y) the amount of such taxes and fees not required to be paid by Purchaser pursuant to preceding sentence of this Section 5.6 ; (iii) one-half (1/2) of all escrow and closing fees relating to the sale of such Property (but not in connection with any financing by Purchaser, which shall be paid solely by

Purchaser); (iv) the costs of the Title Commitments prepared by the Title Company and (v) one-half (1/2) of the fees and charges of third parties in connection with the Surveys, and (vi) the cost of the Environmental Reports.

Purchaser shall be responsible for (a) the amount by which the cost of purchasing the defeasance securities exceeds the principal amount outstanding under the Woodholme MOB Existing Financing as of the Closing Date, and (b) all third-party costs associated with the defeasance of the Existing Woodholme MOB Financing (including the fees and charges of the Woodholme MOB Lender and its counsel, and the fees of the defeasance consultant and its accountants), excluding, however, any fees or charges of the Sellers’ counsel (the costs referred to in the foregoing clauses (a) and (b), excluding the fees and charges of the Sellers’ counsel, are referred to herein as the “ Defeasance Costs ”). Purchaser and Seller acknowledge that the Purchase Price includes $1,900,000, which is the parties’ estimate of the Defeasance Costs. If, pursuant to a statement provided at Closing by the Woodholme MOB Lender, the Defeasance Costs are less than $1,900,000, Purchaser shall receive a credit at Closing equal to the amount by which $1,900,000 exceeds the Defeasance Costs. If, pursuant to a statement provided at Closing by the Woodholme MOB Lender, the Defeasance Costs exceed $1,900,000, Purchaser shall be obligated to deliver into escrow, as part of the Closing Payment, additional funds equal to the amount by which the Defeasance Costs exceed $1,900,000. All other costs pertaining to the sale of each Property shall be allocated as is customary for real estate transactions where such Property is located. The parties agree to cooperate in all reasonable respects to minimize all such costs, premiums, taxes, and fees.

Such notice shall include the name of the proposed Tenant, financial information respecting such Tenant, amount of space involved, the length of the lease term, the proposed financial terms thereof (including any rent abatement periods), the amount of any Leasing Commission, any TI Obligations, a copy of the form of Lease, Lease amendment or other document to be executed and, if the notice relates to a proposed new Work Agreement, a copy of the proposed new Work Agreement. Purchaser shall have five (5) Business Days after receipt of such notice to notify such Seller of its approval or of its objections, if any, to any such proposed Lease or extension or renewal of any existing Lease, or such proposed new Work Agreement, and Purchaser’s failure to approve within such five (5) Business Day period, by e-mail to Mike Daugard at mdaugard@writ.com , shall be deemed to constitute Purchaser’s disapproval of such proposed Lease

or extension or renewal of any existing Lease, or such proposed new Work Agreement. Such Seller shall not enter into any new Lease, amendment, extension or renewal of any existing Lease, or any new Work Agreement, without Purchaser’s prior written consent to the material terms thereof, which consent shall not be unreasonably withheld, conditioned or delayed (and Seller may rely on an email from Michael Gordon on behalf of Purchaser as evidence of such consent). Notwithstanding the foregoing (a) Purchaser’s consent shall not be required for new Leases and renewals or extensions of existing Leases evidencing or reflecting the exercise by Tenants of any rights or options, the terms of which are fixed or determinable as of the Effective Date, under existing Leases; and (b) Purchaser acknowledges and agrees that the Leases and the extensions or renewals of Leases (if any) listed on Exhibit E have been approved by Purchaser. Without limiting the express provisions of this Agreement, nothing in this Agreement shall be interpreted to require that any space at the Properties be leased as a condition to Purchaser’s obligation to proceed with Closing.

6.2.3 Tenant Estoppel Certificates . Prior to Closing, each Seller shall use commercially reasonable efforts to obtain and deliver to Purchaser from the Tenant under each Lease of such Seller’s Property an estoppel certificate in substantially the form attached hereto as Exhibit T-1 or, if any Lease requires a different form, in the form required by such Lease (each, a “ Tenant Estoppel Certificate ”). None of the Sellers shall be in default for failure to obtain any Tenant Estoppel Certificates. Sellers shall promptly deliver to Purchaser copies of draft Tenant Estoppel Certificates and all executed Tenant Estoppel Certificates as the same are received by Seller.

6.2.4 Subordination and Attornment Agreements . If Purchaser’s lender requests that a Tenant agree in writing to subordinate its Lease to a mortgage lien securing Purchaser’s acquisition financing, or to attorn to such lender or its designee or successor in title in connection with the exercise of such lender’s remedies under its acquisition financing lien, then the Seller whose Property is subject to the applicable Lease shall do the following, in each case only upon written request by the Purchaser: (a) such Seller shall request in writing that the applicable Tenant execute a subordination and/or attornment agreement in favor of the Purchaser’s lender, in a form provided by Purchaser’s lender; (b) such Seller shall follow up with the applicable Tenant in writing to determine whether such Tenant will comply with the request made in the foregoing clause (a); and (c) such Seller shall take reasonable steps requested by Purchaser to enforce the obligations of such Tenant under its Lease (to the extent such obligations are referenced in the Purchaser’s request) with respect to the execution of the agreement provided to such Tenant pursuant to the foregoing clause (a), subject to any conditions in such Tenant’s lease, including that the requested agreement contain non-disturbance language in favor of such Tenant. For the avoidance of doubt, it shall not be a condition to Purchaser’s obligation to proceed with the Closing that the Purchaser or its lender obtain any one or more of the subordination or attornment agreements requested from Tenants pursuant to this Section 6.2.4 , and no Seller shall have any obligation to provide any certificate, agreement or other undertaking in lieu of a subordination or attornment agreement not obtained from a Tenant, or to take any action with respect to such agreements except as expressly set forth in this Section 6.2.4 .

6.2.5 Covenants, Conditions and Restrictions of Record . If the Purchaser or the Purchaser’s lender requests that a third party execute a document certifying as to the status of the rights, obligations and/or performance of a Seller, or of such third party, under the covenants, conditions restrictions, easements or other matters of record specifically identified on Exhibit U , such Seller shall do the following, in each case only upon request by the Purchaser: (a) such Seller shall request in writing that the applicable third party execute such certificate, in a form provided by Purchaser or Purchaser’s Lender; (b) such Seller shall follow up with the applicable third party in writing to determine whether such third party will comply with the request made in the foregoing clause (a); and (c) such Seller shall take reasonable steps requested by Purchaser to enforce the obligations of such third party under any covenants, conditions, restrictions, easements or other matters of record (to the extent such obligations are referenced in the Purchaser’s request) with respect to the execution of the certificate provided to such third party pursuant to the foregoing clause (a), subject to any conditions in the applicable documents of record. Notwithstanding the foregoing, in no event shall any Seller be obligated to request a certificate from any owner of a single-family lot, a residential unit in a condominium or cooperative regime, or any other owner of a residential dwelling. For the avoidance of doubt, it shall not be a condition to Purchaser’s obligation to proceed with the Closing that the Purchaser obtain any one or more of the certificates requested from third parties pursuant to this Section 6.2.5 , and no Seller shall have any obligation to provide any certificate regarding the matters set forth in this Section 6.2.5 , or to take any other action with respect to such certificates except as expressly set forth in this Section 6.2.5 .

6.3 Seller’s Indemnity . In addition to other indemnification expressly provided by Sellers herein, Sellers covenant and agree to defend, indemnify, protect, defend, and hold harmless Purchaser, and Purchaser’s respective affiliates, owners, members, partners, employees, lenders, agents and representatives, from and against any and all Claims (a) arising from the use, management, operation, rental, maintenance and ownership of any of the Properties, based upon acts, conduct or omissions (other than by Purchaser) occurring prior to the Closing Date, including without limitation, in connection with any retained liabilities pursuant to Section 2.5 hereof (except that this indemnity shall not apply to any matters or claims which, or from which, Purchaser has expressly waived, released or discharged the Sellers herein or to any matters that are adjusted at Closing pursuant to Section 5.5 ); and (b) caused by or arising out of any material breach by Seller of its representations and warranties in this Agreement. The terms of this Section 6.3 shall survive the Closing until the Survival Date. The indemnification obligations pursuant to this Section 6.3 are subject to the limitations set forth in Sections 9.4 , 9.5 and 9.6 , as applicable, except that the limitations set forth in Section 9.4 shall not apply to such indemnification obligations solely as they relate to payment obligations accruing prior to Closing (and not adjusted at Closing pursuant to Section 5.5 ) under third-party contracts.

If the Closing Date is postponed as provided above in Section 9.1.2 , but if a Purchaser Default remains uncured as of the Closing Date (as postponed), then the Sellers shall have the right to terminate this Agreement by written notice to Purchaser. Upon the termination of this Agreement by the Sellers pursuant to this Section 9.1.3 , the Earnest Money Deposit (and the additional amount, if any, referred to in Section 9.1.1(i)(B)) shall be delivered to the Sellers; and neither party shall have any further rights or obligations hereunder, each to the other, except for rights or obligations of that survive termination as provided herein, and except for rights or obligations relating to the Property or Properties, if any, as to which this Agreement remains in effect. If the Closing does not occur because of a Purchaser Default, Purchaser and the Sellers agree that it would be impractical and extremely difficult to estimate the damages which the Sellers may suffer. Therefore, Purchaser and the Sellers hereby agree that, a reasonable estimate of the total damages that the Sellers would suffer from a Purchaser Default is and shall be an amount equal to the Earnest Money Deposit (and the additional amount, if any, referred to in Section 9.1.1(i)(B)). Sellers acknowledge and agree that the recovery of the Earnest Money Deposit (and the additional amount, if any, referred to in Section 9.1.1(i)(B)) is the sole and exclusive remedy available to Sellers for a breach by Purchaser, that in no event shall Purchaser have any liability whatsoever to the Sellers for money damages, and (effective upon Sellers’ receipt of the Earnest Money Deposit (and the additional amount, if any, referred to in Section 9.1.1(i)(B)) that the Sellers waive any right to make a Claim against the Purchaser for money damages.

9.2 Default by the Sellers Prior to Closing.

9.2.1 If (a) the condition to Closing set forth in the first sentence of Section 8.2.1 is not satisfied as of the Closing Date, (b) after all of the conditions to the Sellers’ obligations to proceed with the Closing have been satisfied or waived by the Sellers, the condition to Closing set forth in Section 8.2.2 is not satisfied as of the Closing Date, or (c) if any Seller willfully causes the failure of any condition in Section 8.2 (any of the foregoing circumstances being referred to herein as a “ Seller Default ”), then Purchaser may elect, as Purchaser’s sole and exclusive remedy for a Seller Default, either: (i) to pursue an action against the Sellers for specific performance, provided that such action must be initiated within ninety (90) days following the date on which the Closing should have occurred in accordance with this Agreement; (ii) when permitted pursuant to Section 9.2.3 , to terminate this Agreement and thereupon to receive the Earnest Money Deposit and reimbursement from Sellers when and to the extent provided below in Section 9.2.3 , or (iii) waive its rights to exercise any right or remedy available to it at law or in equity and proceed to close this transaction. Notwithstanding the foregoing, the refund of the Earnest Money Deposit and the payment of the expenses as set forth herein is not intended as a forfeiture or penalty, but is intended to constitute liquidated damages to Purchaser.

9.2.2 Notwithstanding the foregoing or any other provision of this Agreement to the contrary, before Purchaser may exercise the termination right set forth in Section 9.2.1 , the Sellers shall have the right to cure any Seller Default, and shall be entitled to postpone the Closing Date in order to allow such cure, in accordance with this Section 9.2.2 (the “ Seller Delayed Closing Right ”). If a Seller Default has occurred, Purchaser shall deliver notice to the Sellers on or prior to the Closing Date (a “ Seller Default Notice ”). The Sellers shall have the right, by notice to the Purchaser delivered within five (5) Business Days after the Seller Default Notice, to exercise the Seller Delayed Closing Right to cure any Seller Default. If the Sellers elect to exercise the Seller Delayed Closing Right, the following provisions shall apply:

(a) Subject to Section 9.2.2(c) , if the Seller Default affects any of the Necessary Properties, then: (i) the Closing Date shall be postponed to a date selected by the Sellers in such written notice (but not in excess of thirty (30) days from the initial Closing Date), which postponement shall apply to all of the Properties, unless Purchaser elects, in its sole discretion, to close on the Properties not affected by the Seller Default, and (ii) the parties shall proceed to Closing on the initial Closing Date or as promptly as possible thereafter with respect to the Properties, if any, as to which Purchaser elects in its sole discretion not to postpone Closing, and the Purchase Price payable at such Closing shall be reduced by the sum of the Allocated Amounts of the Properties as to which the Closing Date has been postponed (the amount of such reduction to be due and payable when and if a subsequent Closing occurs under the following clause (iii)), and (iii) if the Sellers cure the Seller Default within such thirty (30) days, Purchaser shall be obligated to purchase the remaining Properties (or the Properties as to which such cure was effected) promptly after such cure is completed; or

(b) If the Seller Default does not affect any of the Necessary Properties, then: (i) the Closing Date shall be postponed to a date selected by the Sellers in such written notice (but not in excess of thirty (30) days from the initial Closing Date), except that such postponement shall apply solely as to the Property or Properties affected by the Seller Default, (ii) the parties shall proceed to Closing on the initial Closing Date or as promptly as possible thereafter with respect to the Properties not affected by the Seller Default, and the Purchase Price payable at such Closing shall be reduced by the sum of the Allocated Amounts of the Properties as to which the Closing Date has been postponed (the amount of such reduction to be due and payable when and if a subsequent Closing occurs under the following clause (iii)), and (iii) if the Sellers cure the Seller Default within such thirty (30) days, Purchaser shall be obligated to purchase the remaining Properties (or the Properties as to which such cure was effected) promptly after such cure is completed.

(c) The postponed Closing Date selected by Sellers pursuant to Section 9.2.2(a) or Section 9.2.2(b) above must be at least 15 days later than the date on which the notice selecting such date is given by Sellers to Purchaser.

9.2.3 If the Sellers do not elect to exercise the Seller Delayed Closing Right within the time frame provided above in Section 9.2.2 , then thereafter the Purchaser shall be entitled to terminate this Agreement in its entirety by written notice to the Sellers given not later than ten (10) Business Days after the Seller Default Notice. If the Closing Date is postponed as to one or more of the Properties as provided above in Section 9.2.2 , but if a Seller Default remains uncured as of the Closing Date (as postponed), then Purchaser shall have the right to terminate this Agreement solely as to the Property or Properties as to which Closing was postponed pursuant to Section 9.2.2 , by written notice to the Sellers given not later than ten (10) Business Days after the Closing Date (as postponed). Upon the termination of this Agreement by the Purchaser pursuant to this Section 9.2.3 : (a) the Earnest Money Deposit shall be returned to Purchaser (provided, however, that if such termination applies to some but not all of the Properties the Purchaser shall receive only the portion of the Earnest Money Deposit corresponding to the Allocated Shares of the Properties as to which this Agreement is terminated, and only if and to the extent such funds remain in escrow after Closing of the remaining Properties has occurred pursuant to this Section 9.2 ); (b) if such termination right arises from a Seller defaulting in its obligations hereunder or from a Seller willfully causing the failure of a condition to Purchaser’s obligation to close, the Sellers shall reimburse Purchaser for third-party out-of-pocket costs and expenses actually incurred by Purchaser in connection with the transaction contemplated by this Agreement, including, the negotiation and preparation of this Agreement and diligence expenses prior to execution hereof, up to a maximum reimbursement amount of $908,699 plus attorneys’ fees and costs, if the same are due from Seller pursuant to Section 12.2 hereof; and (c) neither party shall have any further rights or obligations hereunder, each to the other, except for rights or obligations of that survive termination as provided herein, and except for rights or obligations relating to the Property or Properties, if any, as to which this Agreement remains in effect.

9.2.4 Purchaser acknowledges and agrees that the remedies set forth in this Section 9.2 are the sole and exclusive remedies available to Purchaser for a breach by Sellers, that in no event shall Sellers have any liability whatsoever to Purchaser for money damages, and that Purchaser waives any right to make a Claim against the Sellers for money damages other than those provided in Sections 9.2.1 , 9.2.2 and 9.2.3 hereof.

9.3 Material Adverse Effect.

9.3.1 For purposes of this Agreement, “ Material Adverse Effect ” means a material adverse effect on the assets comprising the Properties, the Purchaser’s title to one or more of the Properties after Closing, or the results of operations or financial condition of one or more of the Properties caused by any event, circumstance, development, condition, occurrence, state of facts, change or effect, in each case considering all of the Properties as a single asset, and in each

case excluding the impact of any event, circumstance, development, condition, occurrence, state of facts, change or effect caused by Purchaser or any Person acting on Purchaser’s behalf. For purposes of determining the existence of a Material Adverse Effect, any single adverse effect, or combination of adverse effects, caused by one or more events, circumstances, developments, conditions, occurrences, states of fact, changes or effects (including, without limitation, Proceedings, Liens and Violation Notices) shall not be considered a Material Adverse Effect unless and until the Liquidated Amount with respect to such single adverse effect or combination of adverse effects equals or exceeds 2% of the Purchase Price.

9.3.2 If it is necessary to determine the potential exposure, the reasonable cost to Discharge or remediate, or the reasonable unpaid amount of any event, circumstance, development, condition, occurrence, state of facts, change or effect (collectively, the “ Liquidated Amount ”) in order to apply the provisions of Section 9.3.1 or Section 8.2.1 , the Sellers and Purchaser shall mutually agree on such determination(s), each acting in good faith and in a commercially reasonable manner.

9.4 Limitations of Purchaser’s Post-Closing Claims . Notwithstanding anything in this Agreement to the contrary, including any language limiting representations and warranties or covenants of Sellers to each’ s respective Property, but in all cases subject to the following sentence, each of the Sellers shall be jointly and severally liable for the obligations and liabilities of each other Seller under this Agreement, subject to the following limitations. Notwithstanding any provision to the contrary herein or in any document or instrument (including any deeds, bill of sale or assignments) executed by any Seller and delivered to Purchaser at or in connection with the Closing (collectively, “ Closing Documents ”), no Seller shall have (and each Seller is exculpated and released from) any Claim or liability whatsoever with respect to, and Purchaser shall be forever barred from making or bringing any Claims or asserting any liability against a Seller with respect to (i) any of the representations and warranties, covenants or indemnities contained in this Agreement or in any Closing Document made by any of the Sellers, unless and until the aggregate amount of all losses actually incurred by the Purchaser for a breach of the representations and warranties made and undertaken in this Agreement by any or all of the Sellers exceeds the Threshold Amount (in which case Purchaser may bring a Claim for the total amount of such losses, including amounts below the Threshold Amount); and (ii) any of the representations and warranties made and undertaken in this Agreement or in any document executed or delivered at Closing by any or all of the Sellers, if and to the extent that the total liability of all of the Sellers for breaches of any of the foregoing would exceed the Cap Amount. As used herein: (i) “ Threshold Amount ” means an amount equal to One Hundred Thousand Dollars ($100,000), and (ii) the “ Cap Amount ” means an amount equal to 2% of the Purchase Price. The Threshold Amount and Cap Amount shall not apply to Seller Estoppel Certificates or the Sellers’ indemnification obligations under Sections 5.5.13 , 7.2.4(l) , Article 10 , and Section 12.22.4 of this Agreement.

9.5 Other Limitations of Purchaser’s Claims . Purchaser shall not make any Claim or bring any proceeding to enforce the liability of a Seller unless Purchaser believes, in good faith, that it would be entitled to recover all or a portion of the alleged damages or other liability notwithstanding the limitations on such Seller’s liability set forth above in Section 9.4 . In no event shall any Seller be liable for indirect, consequential or punitive damages of any kind, and Purchaser shall be barred from and hereby waives any Claim for the same.

9.6 Survival of Purchaser’s Claims . The representations and warranties, covenants and indemnities of the Sellers contained herein or in any Closing Document shall survive until the date that is nine (9) months from the Closing Date (the “ Survival Date ”); except with respect to any representation, warranty, covenant or indemnity that survives for a longer period pursuant to an express provision of this Agreement. Any permitted Claim that Purchaser may have at any time against a Seller for breach of any such representation, warranty, covenant or indemnity, whether known or unknown, with respect to which a written notice providing specific details of the alleged breach to the extent known by Purchaser (a “ Claim Notice ”) has not been delivered to the Sellers on or prior to the Survival Date, shall not be valid or effective and the party against whom such Claim is asserted shall have no liability with respect thereto. Any Claim that Purchaser may have at any time against a Seller for a breach of any such representation or warranty, or its covenants and indemnities whether known or unknown, with respect to which a Claim Notice has been delivered to the Sellers on or prior to the Survival Date (a “ Pending Claim ”) may be the subject of subsequent litigation brought by Purchaser against the Sellers. For the avoidance of doubt, on the Survival Date, each Seller shall be fully discharged and released (without the need for separate releases or other documentation) from any liability or obligation to Purchaser and/or its successors and assigns with respect to any Claims or any other matter relating to this Agreement or any Closing Document, except for those matters that are then the subject of the pending Claim Notice delivered by Purchaser to the Sellers that is still pending on the Survival Date.

9.7 Survival of Sellers’ Claims . Except as otherwise specifically set forth in this Agreement, the representations and warranties, covenants and indemnities of Purchaser contained herein or in any document or instrument executed by Purchaser and delivered to the Sellers at or in connection with the Closing (collectively, “ Purchaser Closing Documents ”) shall survive only until the Survival Date. Any Claim that the Sellers may have any time against Purchaser for breach of any such representation, warranty, covenant, or indemnity, whether known or unknown, with respect to which a Claim Notice has not been delivered to Purchaser on or prior to the Survival Date, shall not be valid or effective and the party against whom such Claim is asserted shall have no liability with respect thereto. Any Claim that the Sellers may have at any time against Purchaser for a breach of any such representation or warranty, covenants and indemnities whether known or unknown, with respect to which a Claim Notice has been delivered to Purchaser on or prior to the Survival Date may be the subject of subsequent litigation brought by the Sellers against Purchaser. For the avoidance of doubt, on the Survival Date, Purchaser shall be fully discharged and released (without the need for separate releases or other documentation) from any liability or obligation to the Sellers and/or their successors and assigns with respect to any Claims or any other matter relating to this Agreement or any Purchaser Closing Document, except for those matters that are then the subject of the pending Claim Notice delivered by the Sellers to Purchaser that is still pending on the Survival Date.

9.8 Limitations of Seller’s Claims . Notwithstanding any provision to the contrary herein or in any Closing Documents (other than a provision that expressly provides that this Section 9.8 is not applicable, in which case such provision shall control over this Section 9.8 ), Purchaser shall not have (and Purchaser is exculpated and released from) any Claim or liability whatsoever with respect to, and Seller shall be forever barred from making or bringing any Claims or asserting any liability against Purchaser with respect to (i) any of the representations and warranties, covenants or indemnities contained in this Agreement or in any Closing Document made by Purchaser, unless and until the aggregate amount of all losses actually incurred by the sellers for a breach of the

representations and warranties made and undertaken in this Agreement by any or all of the Sellers exceeds the Threshold Amount (in which case Seller may bring a Claim for the total amount of such losses, including amounts below the Threshold Amount); and (ii) any of the representations and warranties made and undertaken in this Agreement or in Closing Documents by Purchaser, if and to the extent that the total liability of Purchaser for breaches of any of the foregoing would otherwise exceed the Cap Amount. Sellers shall not make any Claim or bring any proceeding to enforce the liability of Purchaser unless Sellers believe, in good faith, that Sellers would be entitled to recover all or a portion of the alleged damages or other liability notwithstanding the limitations on Purchaser’s liability set forth in this Section 9.8 . In no event shall any Purchaser be liable for indirect, consequential or punitive damages of any kind, and Seller shall be barred from and hereby waives any Claim for the same. The provisions of this Section 9.8 shall not apply to a claim by Seller against Purchaser for the Earnest Money Deposit.

9.9 Limitations on Liability .

9.9.1 The parties hereto confirm and agree that in each instance herein where a party or its Affiliates is entitled to payment or reimbursement for damages, costs or expenses pursuant to the terms and conditions of this Agreement, any payment or reimbursement made to such party shall be conclusively deemed to be for the account of both such party and its Affiliates, it being acknowledged and agreed that a payment or reimbursement made to such party for damages, costs or expenses shall be sufficient to satisfy all claims for payment or reimbursement of such party and its Affiliates. In no event will either party be liable to the other for any indirect, special, consequential or punitive damages of any kind.

9.9.2 To the maximum extent permitted by applicable law, no shareholder, director, officer or employee of any party to this Agreement shall have any personal liability with respect to the liabilities or obligations of such party under this Agreement or any document executed by such party pursuant to this Agreement.

Any waiver by either party shall be effective only if in a writing delivered to the other party hereto and setting forth, with specificity, the covenant, term,

provision or condition so waived. Any such waiver shall not constitute or be construed as a continuing waiver of any subsequent default.

12.12 Headings . The headings of this Agreement are for purposes of convenience only and shall not limit or define the meaning of the provisions of this Agreement.

12.13 Risk of Loss . With respect to each Property, the risk of loss shall be as follows:

12.13.1 Risk of Loss . Until the Closing Date, each Seller shall bear the risk of loss resulting from damage to such Seller’s Property by fire or other casualty (collectively “ Casualty ”). If, prior to the Closing Date, a Property shall be damaged by any Casualty, such Property’s Seller shall promptly deliver to Purchaser a Notice (“ Casualty Notice ”) of such event. Upon Purchaser’s receipt of a Casualty Notice, such Seller and Purchaser shall meet promptly to estimate the cost to repair and restore the Improvements to good condition and to replace the damaged Personal Property (“ Casualty Renovation Cost ”). If the parties are unable to agree on the cost of restoration, the matter will be submitted to an engineer or contractor designated by such Seller and an engineer or contractor designated by Purchaser, each licensed to practice in the jurisdiction in which the Land is located, and the engineers or contractors shall resolve the dispute. If the engineers or contractors fail to resolve the dispute, they shall designate a third engineer or contractor, who shall determine such resolution, which determination shall be binding on the Sellers and on the Purchaser. Each party hereto shall bear the costs and expenses of its own engineer or contractor. The cost of a third engineer or contractor, if any is appointed by the parties’ respective engineers or contractors, shall be borne one half (1/2) by the Sellers and one half (1/2) by the Purchaser.

12.13.2 Material Loss . If the Casualty Renovation Cost for any single Property exceeds five percent (5%) of such Property’s Allocated Amount, or if the Casualty Renovation Costs, in the aggregate for all of the Properties that have suffered a casualty, exceeds two and one half percent (2.5%) of the Purchase Price, then Purchaser may, at its option, elect to terminate this Agreement with respect to the impacted Property or Properties provided the impacted Property is not one of the Necessary Properties. If the impacted Property is a Necessary Property, Purchaser shall have the option of terminating this Agreement with respect to all Properties. Such termination right may be exercised only by Notice to the Sellers within ten (10) business days after the date that the Casualty Renovation Cost for such Property or in the aggregate for all Properties that have suffered casualties is determined to exceed the applicable amount stated in the preceding sentence (and if necessary the Closing Date will be extended to accommodate such ten (10) business day period), and in the event of a termination hereof with respect to the impacted Property or Properties only, the Purchase Price shall be reduced by the Allocated Amount of the terminated Property or Properties. If this Agreement can be terminated pursuant to the preceding provisions of this Section 12.13.2 , but Purchaser elects not to terminate this Agreement pursuant to such provision, then the Closing shall take place as provided herein without reduction of the Purchase Price, and the Sellers shall assign the insurance proceeds to Purchaser and the Sellers shall pay to Purchaser the amount of any deductible not already otherwise paid by the Sellers under applicable insurance policies.

12.13.3 Nonmaterial Loss . If the Casualty Renovation Cost for any single Property does not exceed five percent (5%) of such Property’s Allocated Amount, or if the Casualty Renovation Costs, in the aggregate for all Properties that have suffered a casualty, does not exceed two and one half percent (2.5%) of the Purchase Price, then, in any such event, neither party hereto shall have any right to terminate this Agreement, but the Closing shall take place as provided herein without reduction of the Purchase Price, and the Sellers shall assign the insurance proceeds to Purchaser and shall pay or credit to Purchaser at Closing for any deductible amount under applicable insurance policies.

12.13.4 Eminent Domain . If, prior to the Closing Date, any Seller receives notice that any portion of one of its Properties (or access or other material rights in connection therewith) as would, in Purchaser’s reasonable judgment, materially adversely affect the operation of such Property or uses of such Property is, or has been threatened in writing by a governmental authority of competent jurisdiction, to be taken by condemnation or eminent domain, such Seller shall promptly notify Purchaser, and at the election of Purchaser this Agreement shall, upon the giving of Notice of such event or of the condemning authorities’ intention so to take such Property, terminate with respect only to the impacted Property, provided the impacted Property is not one of the Necessary Properties, but the Closing shall proceed with respect to the remaining Properties (with the Purchase Price reduced by the Allocated Purchase Price of the impacted Property). If the impacted Property is a Necessary Property, Purchaser shall have the option of terminating this Agreement with respect to all Properties . If Purchaser does not elect to terminate this Agreement prior to the Closing Date, on the Closing Date all of the proceeds of any award or payment made or to be made by reason of such taking shall be assigned by such Seller to Purchaser, and any money theretofore received by such Seller in connection with such taking shall be paid over to Purchaser, whereupon Purchaser shall pay the Purchase Price without abatement by reason of such taking. Such Seller shall not settle, agree to, or accept any award or payment in connection with a taking of less than all of the Property without obtaining Purchaser’s prior written consent in each case, which consent shall not be unreasonably withheld or delayed. As used in this Section, “material rights” or “materially adversely affect” means, with respect to a Property, a taking or condemnation that (a) would reduce available parking below that required by, or in general cause a violation of, any Legal Requirements or any Permitted Exceptions, (b) would restrict or impede access to the Property, (c) would materially impair the ability to operate the Property as a medical office building, (d) would result in a condemnation award reasonably estimated to exceed five percent (5%) of such Property’s Allocated Amount, or (e) would result in a condemnation award that, when combined with the amount of all other condemnation awards for takings or condemnations affecting any of the other Properties, would reasonably be estimated to exceed two and one-half percent (2.5%) of the Purchase Price.

The words “herein,” “hereof,” “hereunder” and words of similar reference mean and refer to this Agreement. The words “this Agreement” include the exhibits, schedules addenda

and any future written modifications, unless otherwise indicated by the context. The words “will,” “shall” and “must” in this Agreement indicate a mandatory obligation. All dollar amounts set forth in this Agreement are stated in United States Dollars, unless otherwise specified. The words “day” and “days” refer to calendar days unless otherwise stated. The words “business day” refer to a day other than a Saturday, Sunday or Legal Holiday (hereinafter defined). The words “month” and “months” refer to calendar months unless otherwise stated. The words “year” and “years” refer to calendar years unless otherwise stated. If any date herein set forth for the performance of any obligations by Seller or Purchaser or for the delivery of any instrument or notice as herein provided should fall on a Saturday, Sunday or Legal Holiday, the compliance with such obligations or delivery will be deemed acceptable on the next business day following such Saturday, Sunday or Legal Holiday. As used herein, the term “ Legal Holiday ” will mean any local or federal holiday on which post offices are closed in the State of Maryland.

12.15 Covenants, Representations and Warranties . By proceeding with the closing of the sale transaction, the Sellers and Purchaser shall be deemed to have waived, and so covenant to waive, any claims of defaults or breaches by the other party existing on or as of the Closing Date whether under this Agreement or any other document or instrument executed by the other party in connection with this transaction, of which the waiving party was made aware by Notice from the defaulting or breaching party (and, if applicable, which is described on the Sellers certification of representations and warranties to be delivered at Closing) prior to the Closing Date for which the other party shall have no liability.

12.16 Press Releases; Confidentiality . Either party may issue press releases and other public communications announcing the transaction contemplated by this Agreement with the consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed); provided that the Sellers may issue press releases without the consent of Purchaser if such press releases are substantially in the form emailed by Mike Daugard to Mike Gordon on September 27, 2013. In addition and notwithstanding anything to the contrary herein, the Sellers and their Affiliates may file and describe this Agreement in flings, and may make such other filings with the SEC as are required in connection with the matters contemplated by this Agreement. Notwithstanding the foregoing, no such press release or other communication shall include any information (other than the identification of the parties) that is required to be kept confidential pursuant to the remaining provisions of this Section 12.16 . Purchaser and Sellers shall refrain, and shall cause their agents and representatives to refrain, from disclosing in any manner whatsoever, (a) the information provided by the other party or its representatives, or (b) any analyses, compilations, studies or other documents or records prepared by or on behalf of the other party, in connection with this transaction, without first obtaining the written consent of the other Party (collectively, “ Proprietary Information ”). The foregoing shall not preclude Purchaser or Sellers (i) from discussing the Proprietary Information with any person who is employed by Purchaser or Sellers or who, on behalf of Purchaser or Sellers, is actively and directly participating in the purchase and sale of all of the Properties, including, without limitation, to shareholders, partners, members, existing or prospective lenders, attorneys, accountants and other consultants and advisors, (ii) from complying with all laws, rules, regulations and court orders, including, without limitation, governmental regulatory, disclosure, tax and reporting requirements, or (iii) from Purchaser utilizing such Proprietary Information after Closing in its ownership and operation of the Properties; provided, however, that if Purchaser or Sellers are required by applicable law or legal process to disclose any Proprietary Information, the parties agree to furnish only that portion of the Proprietary Information

which such party is legally compelled to disclose and to use its commercially reasonable efforts to obtain assurance that, if possible, confidential treatment will be accorded to the Proprietary Information. Purchaser and Sellers shall inform their respective representatives of the confidential nature of the Proprietary Information and shall direct them to be bound by the terms of this section. In addition to any other remedies available to the non-defaulting party, the non-defaulting party shall have the right to seek equitable relief, including, without limitation, injunctive relief or specific performance, against the defaulting party under this Section in order to enforce the provisions of this section. The provisions of such confidentiality agreement shall survive any termination of this Agreement. Except as otherwise expressly provided in this Agreement, Purchaser agrees not to contact, directly or indirectly, any personnel at any of the Properties prior to the Closing Date without Sellers’ consent, and agrees to be liable for all of the Sellers’ damages in the event of any such unpermitted contact by Purchaser or any of its agents or representatives (excluding indirect, consequential or punitive damages of any kind).

12.17 No Third-Party Beneficiaries . Except as otherwise expressly provided herein, the Sellers and Purchaser agree that there are no third parties who are intended to benefit from or who are entitled to rely on any of the provisions of this Agreement. No third party shall be entitled to assert any claims or to enforce any rights whatsoever pursuant to this Agreement. Except as otherwise expressly provided herein, the covenants and agreements provided in this Agreement are solely for the benefit of the Sellers and Purchaser and their permitted successors and assigns respectively.

12.18 Facsimile Signatures . The execution of this Agreement and all Notices given hereunder and all amendments hereto, may be effected by facsimile signatures, all of which shall be treated as originals; provided, however, that the party receiving a document with a facsimile signature may, by Notice to the other, require the prompt delivery of an original signature to evidence and confirm the delivery of the facsimile signature. Purchaser and the Sellers each intend to be bound by its respective facsimile transmitted signature, and is aware that the other party will rely thereon, and each party waives any defenses to the enforcement of the Agreement, and documents, and any Notices delivered by facsimile transmission.

12.19 Severability . If any term or provision of this Agreement or the application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Agreement, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each such term and provision of this Agreement shall be valid and be enforced to the fullest extent permitted by law.

12.20 Consents and Approvals . Except as otherwise expressly provided herein, any approval or consent provided to be given by a party hereunder may be given or withheld in the absolute discretion of such party.

12.21 WAIVER OF JURY TRIAL . THE PARTIES HEREBY IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR

MODIFICATIONS TO THIS AGREEMENT. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

12.22 1031 Exchange . The Sellers and/or Purchaser (or a parent entity of a Seller or the Purchaser that is recognized as a separate entity for federal income tax purposes) may consummate the sale of the Properties as part of a so-called like kind exchange (the “ Exchange ”) pursuant to § 1031 of the Internal Revenue Code of 1986, as amended (the “ Code ”), in accordance with the following provisions:

12.22.1 If the Sellers or Purchaser elects to effectuate an Exchange, and such Exchange cannot be effected for any reason, the Closing shall not be delayed and Sellers and Purchaser shall be obligated to close the transaction as a purchase and sale pursuant to the terms of this Agreement.

12.22.2 To exercise its right under this Section 12.22 to exchange, rather than sell or purchase, as applicable, all or some of the Properties, the Sellers or Purchaser shall provide the other party with a written statement stating its intent to enter into an Exchange not later than fifteen (15) days prior to the Closing Date.

12.22.3 If the Sellers or Purchaser exercises its right to exchange, rather than sell or purchase, as applicable, all or some of the Properties, the Sellers may, on or before the Closing Date, assign its rights under this Agreement to a “qualified intermediary”, as defined in Treasury Regulation 1.103(k) I (g)(4) (the “ Accommodator ”) or an Exchange Accommodation Titleholder (“ EAT ”), or transfer such Properties to the Accommodator or the EAT, subject to all of Purchaser’s rights and remedies under this Agreement, including, without limitation, Purchaser’s right to acquire such Properties at the Closing or Purchaser may, on or before the Closing Date, assign its rights under this Agreement to an Accommodator or an EAT, or direct the Sellers to convey such Properties to an Accommodator or an EAT at Closing, subject to all of the Sellers’ rights and remedies under this Agreement; provided, however, that the Sellers or Purchaser shall notify the other party of the identity of the Accommodator or EAT within five (5) days after designation of same, and further provided that the party designating an Accommodator or EAT (the “ Designating Party ”) shall remain liable for the performance of all obligations, representations, warranties and covenants of the Designating Party hereunder. In any case, all payments that Purchaser is obligated to make to the Sellers under this Agreement shall be made to the Accommodator or the EAT and not to Seller. Purchaser and the Sellers agree to cooperate with each other and the Accommodator or EAT in arranging the Exchange. The party which is not the Designating Party (the “ Non-Designating Party ”) shall execute any documents reasonably requested by the Designating Party and the Accommodator or EAT to facilitate the Exchange as a like-kind exchange under Section 1031 of the Code and the Treasury Regulations effective thereunder at the time of Closing hereunder, including, but not limited to, any appropriate amendments to this Agreement and any appropriate escrow instructions; provided, however, that no such document shall adversely affect the Non-Designating Party in any respect or change any of the economic terms and conditions of the transaction with respect to the Non-Designating Party or modify or limit the Non-Designating Party’s rights and remedies under this Agreement. The Non-Designating Party shall not be obligated to incur any costs, expenses, losses, liabilities or damages greater than those the Non-Designating Party would have incurred had the Designating Party not elected to effect an exchange. The Designating Party shall reimburse the Non-Designating Party on demand for all costs and expenses

incurred by the Non-Designating Party in excess of those that would have been incurred if the Designating Party had not elected to effect an Exchange.

12.22.4 In no event shall the Non-Designating Party be obligated to acquire title to any other property, in connection with such Exchange. Purchaser’s sole obligation in connection with any Exchange shall be to acquire the Property from Seller or its assignee in exchange for the Purchase Price in accordance with the terms of this Agreement. The Designating Party agrees to defend, indemnify, and hold the Non-Designating Party free and harmless from all costs, expenses, losses, damages or liability, including but not limited to reasonable attorney’s fees and costs of suit, arising out of or in connection with any Exchange and the Non-Designating Party's cooperation hereunder. Each party acknowledges that neither of them is making any representations, and neither of them is relying on any representations of the other party or the other party's counsel, with respect to the federal, state or local income tax treatment of either of them in connection with this transaction, and neither party shall have any liability in connection with any tax treatment received by either of them in connection with this transaction, including, without limitation, any failure of this transaction to qualify as an exchange under Section 1031 of the Code.

12.23 Montgomery County Provisions . The following disclosures are made pursuant to applicable law in Montgomery County, Maryland:
