The Escrow shall include both the Escrow Agent’s handling of the Earnest Money Deposit and Escrow Agent’s handling of any other documents and deliveries deposited with Escrow Agent at any time up to, and including, the Closing Date.

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 a commitment for title insurance (the “Title Commitment”) addressing the status of title to the 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 the Title Commitment. Purchaser has had the opportunity to review and approve the Title Commitment. The Title Commitment is identified on Exhibit P. The parties acknowledge and agree that the Purchaser has received for the Property a survey that complies with the Survey Standards. The survey, including all revisions required by Purchaser, is identified on Exhibit Q (such survey is referred to herein as the “Survey”). 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 Commitment and the Survey are Permitted Exceptions, and that Seller shall not be obligated to Cure any of such Liens or Encumbrances. Seller 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. Seller agrees to Cure, prior to or at Closing, (i) all Voluntary Liens; and (ii) the Involuntary Liens, if any, listed on Exhibit S. If Seller or Purchaser becomes aware that an Involuntary Lien has arisen after the effective date of the Title Commitment, 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 Seller has received notice pursuant to this Section 4.1.2 after the date hereof and prior to Closing (each,

WRIT MOB – Transaction II

a “New Lien”), does not exceed $25,000, then Seller shall be obligated to Cure such New Lien prior to or at Closing, at 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 $25,000, then Seller 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 $25,000. Seller shall notify Purchaser of its election with respect to each New Lien for which the cost to Discharge (together with the cost to Discharge all other New Liens) exceeds $25,000, within five (5) Business Days after Seller either sends or receives notice of such New Lien pursuant to the second sentence of this Section 4.1.2. If Seller does not make such election in writing within such five (5) Business Days, Seller shall be deemed to have elected not to Cure such New Lien. If Seller has elected to not Cure a New Lien for which the cost to Discharge (together with the cost to Discharge all other New Liens) exceeds $25,000, Purchaser shall be entitled to terminate this Agreement by written notice to Seller, 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 Seller fails to Cure a New Lien by Closing that 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 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. Seller agrees not to create or subject the 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 Purchaser. Any New Encumbrance that Seller creates or subjects the 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 Seller or Purchaser first becomes aware of an Encumbrance (other than a Seller-Created Encumbrance) that was not disclosed by the Title Commitment or revisions thereof prior to the Effective Date (a “New Encumbrance”), Purchaser or 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 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, Seller shall give notice to Purchaser, within ten (10) days of Purchaser’s objection notice (the “Seller Response Period”), as to whether Seller agrees to attempt to Cure such New Encumbrance. If Seller elects in writing to attempt to Cure a New Encumbrance to which Purchaser timely objects pursuant to this Section 4.1.3, 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 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

WRIT MOB – Transaction II

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 Seller fails 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, Seller made available to Purchaser certain information, documents, agreements and reports in Seller’s possession or control relating to the Property (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 the Property itself prior to the date hereof. By executing this Agreement, Purchaser acknowledges that it has completed its inspections and studies of the Property 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, Seller shall cooperate and provide Purchaser with reasonable and continuing access to the Real Property included in the Property upon commercially reasonable Notice to Seller 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 Seller’s prior written consent in each instance, which may be granted or withheld in Seller’s 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 Property with any on-site employees of the Property without Seller’s consent; provided, however, that Purchaser may meet with any Property’s asset manager upon commercially reasonable Notice to Seller but, if required by Seller, only in the presence of a Seller representative. Seller shall have the right to have a representative of Seller present during all inspections, examinations or interviews concerning Seller’s Real Property by Purchaser.

4.2.2 Prior to any entry by Purchaser or any of Purchaser’s designees onto the 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 Seller, covering all of Purchaser’s activities at the Property, with a single limit of liability (per occurrence and aggregate) of not less than $2,000,000.00; and (ii) deliver to Seller a Certificate of Insurance, evidencing that such insurance is in force and effect, and evidencing that Seller 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.

WRIT MOB – Transaction II

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 Seller, any Property or Tenants of the Property, and without unreasonably interfering with or disturbing any Tenants or employees at the Property. 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 the Property caused by Purchaser’s inspection to its condition immediately preceding such inspections and examinations and will keep the Property 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, if any, 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 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 (if any) 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 Seller. Seller 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 Seller; 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 Seller has delivered notice terminating such Contract on or before October 15, 2013, such Contract shall be an Assumed Contract. Seller 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 the Property being retained by 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 the Property. Contracts pursuant to which services are rendered to one or more properties that are not the Property are designated as such on Exhibit C. Notwithstanding anything to the contrary, if Seller has engaged a manager to manage the Property, 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 Seller, or Seller’s 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

WRIT MOB – Transaction II

return to Seller or destroy (and confirm in a notice to Seller that Purchaser has returned or destroyed) all such information and documentation, and all copies thereof.

4.2.7 Except as expressly provided herein, Seller makes no 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 the Property (e.g., that such materials are complete, accurate or the final version thereof, or that all such materials are in 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 Property, and, in doing so, Purchaser shall rely exclusively on its own independent investigation and evaluation of every aspect of the Property and not on any materials supplied by Seller. 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 Seller 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.

5.5 Prorations.

5.5.1 Taxes. At or prior to Closing Sellers shall pay all amounts due and owing for the Property as of the Closing Date with respect to real estate and personal property general and special taxes and assessments. All non-delinquent real estate and personal property general and special taxes and assessments for the 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 the 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) 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 the Property for any period prior to the Closing Date, and (ii) Seller is responsible for all taxes due and payable for the Property prior to the Closing Date. Seller shall have the right to continue and control any contest of any taxes or assessments for the Property 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 Property 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. Seller 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. To the extent commercially reasonable and practicable, Seller and Purchaser shall obtain billings and meter readings as of the Business Day preceding the Closing

WRIT MOB – Transaction II

Date to aid in the proration of charges for gas, electricity and other utility services which are not the direct responsibility of Tenants. 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. 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 Seller in respect of services provided to the Property. Purchaser shall arrange for placing all utility services and bills in its own name as of the Closing Date.

5.5.3 Reserved.

Any net adjustment in favor of Purchaser shall be paid in cash by Seller to Purchaser no later than thirty (30) days after the Final Closing Adjustment. Any net adjustment in favor of Seller shall be paid in cash by Purchaser to Seller 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. If any Tenants pay Additional Rent, 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”), Seller and Purchaser shall adjust the Closing Date proration of Additional Rent pursuant to Section 5.5.10(b) above, as follows:

WRIT MOB – Transaction II

(i) The parties shall determine the aggregate amount of expenses that were incurred by Purchaser or by 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 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 Seller and Purchaser, and Seller 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. Seller shall fully cooperate with Purchaser in order to complete the Final Closing Adjustment and Seller shall provide Purchaser with any information reasonably requested by Purchaser or as may be

WRIT MOB – Transaction II

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 Seller and Purchaser.

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 occurs, (a) the provisions of this Section 5.5 shall survive, (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, 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, 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.

approval (provided, however, Seller may make any alterations or changes to the Property that are required by any Lease or by applicable law without Purchaser’s prior approval); (iv) to maintain in effect all policies of casualty and liability insurance or similar policies of insurance, with no less than the limits of coverage now carried with respect to the Property, and (v) to promptly deliver to Purchaser any notices of breaches or defaults sent or received by Seller in connection with the Leases, Assumed Contracts or Permitted Exceptions.

WRIT MOB – Transaction II

9.1 Default by Purchaser Prior to Closing.

9.1.1 Default by Purchaser Prior to Closing. If (a) any of the representations or warranties made by Purchaser herein are inaccurate as of the Closing Date in any material respect, (b) after all of the conditions to Purchaser’s obligations to proceed with the Closing have been satisfied or, in lieu thereof, waived by Purchaser, Purchaser fails to deposit the Closing Payment and the documents and instruments specifically listed in Section 5.3 hereof with Escrow Agent on the Closing Date, or (c) Purchaser fails or refuses to perform any of Purchaser’s other material covenants or agreements to be performed by Purchaser under this Agreement at or before Closing (any of the foregoing circumstances being referred to herein as a “Purchaser Default”), then Seller’s sole remedies shall be (i) to terminate this Agreement and receive the Earnest Money Deposit, whereupon the Earnest Money Deposit shall be delivered to Seller as liquidated damages and neither party shall have any further rights or obligations hereunder, each to the other, except for any obligations or rights that expressly survive termination of this Agreement, and the right of Seller to collect such liquidated damages from Purchaser and Escrow Agent; or (ii) to waive the Purchaser Default and consummate the transactions contemplated hereby.

WRIT MOB – Transaction II

9.1.2 Notwithstanding the foregoing or any other provision of this Agreement to the contrary, before Seller may exercise the termination right set forth in Section 9.1.1, the Purchaser shall have the right to cure any Purchaser Default, and shall be entitled to postpone the Closing Date in order to allow such cure, in accordance with this Section 9.1.2 (the “Purchaser Delayed Closing Right”). If a Purchaser Default has occurred, Seller shall deliver notice to the Purchaser on or prior to the Closing Date (a “Purchaser Default Notice”). Purchaser shall have the right, by notice to Seller delivered within five (5) Business Days after the Purchaser Default Notice, to exercise the Purchaser Delayed Closing Right to cure any Purchaser Default. If Purchaser elects to exercise the Purchaser Delayed Closing Right, then the Closing Date shall be postponed to a date selected by Purchaser in such written notice (but not in excess of fifteen (15) days from the initial Closing Date).

9.1.3 If Purchaser does not elect to exercise the Purchaser Delayed Closing Right within the time frame provided above in Section 9.1.2, then thereafter Seller shall be entitled to terminate this Agreement in its entirety by written notice to Purchaser. 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 Seller shall have the right to terminate this Agreement by written notice to Purchaser. Upon the termination of this Agreement by Seller pursuant to this Section 9.1.3, the Earnest Money Deposit shall be delivered to Seller; 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, if any, as to which this Agreement remains in effect.

Therefore, Purchaser and Seller hereby agree that, a reasonable estimate of the total damages that Seller would suffer from a Purchaser Default is and shall be an amount equal to the Earnest Money Deposit. Seller acknowledges and agrees that the recovery of the Earnest Money Deposit is the sole and exclusive remedy available to Seller for a breach by Purchaser, that in no event shall Purchaser have any liability whatsoever to Seller for money damages, and (effective upon Seller’s receipt of the Earnest Money Deposit) that Seller waives any right to make a Claim against the Purchaser for money damages.

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; (b) if such termination right arises from Seller defaulting in its obligations hereunder or from Seller willfully causing the failure of a condition to Purchaser’s obligation to close, Seller 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 $11,488 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.

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 Seller, that in no event shall Seller have any liability whatsoever to Purchaser for money damages, and that Purchaser waives any right to make a Claim against Seller for money damages other than those provided in Sections 9.2.1, 9.2.2 and 9.2.3 hereof.

Any Claim that Purchaser may have at any time against 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 Seller on or prior to the Survival Date (a “Pending Claim”) may be the subject of subsequent litigation brought by Purchaser against Seller.

Any Claim that Seller 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 Seller 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 Seller and/or its 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 Seller to Purchaser that is still pending on the Survival Date.

MISCELLANEOUS

12.1 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Maryland. If any legal action is necessary to enforce the terms and conditions of this Agreement, the parties hereby agree that the federal and state courts in the State of Maryland shall be the sole jurisdiction and venue for the bringing of the action.

12.2 Professional Fees and Costs. If a lawsuit, arbitration or other proceedings are instituted by any party to enforce any of the terms or conditions of this Agreement against any other party hereto, the prevailing party in such litigation, arbitration or proceedings shall be entitled, as an additional item of damages, to such reasonable attorneys’ and other professional fees and costs (including, but not limited to, witness fees), court costs, arbitrators’ fees, arbitration administrative fees, travel expenses, and other reasonable, actual, out-of pocket expenses or costs of such other proceedings, which amount shall be determined by any court of competent jurisdiction, arbitrator or other judicial or quasi-judicial body having jurisdiction thereof, whether or not such litigation or proceedings proceed to a final judgment or award. For the purposes of this section, any party receiving an arbitration award or a judgment for damages or other amounts shall be deemed to be the prevailing party, regardless of amount of the damage awarded or whether the award or judgment was based on all or some of such party’s claims or causes of action, and any party against whom a lawsuit, arbitration or other proceeding is instituted and later voluntarily dismissed by the instituting party shall be deemed to be the prevailing party.

12.3 Exhibits a Part of This Agreement. The Exhibits attached hereto are incorporated in this Agreement by reference and are hereby made a part hereof.

12.4 Executed Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document. This Agreement shall become effective upon the due execution and delivery of this Agreement to the parties hereto.

12.5 Assignment. Purchaser may not assign, convey and otherwise transfer all or any part of its interest or rights herein without the prior written consent of Seller, which consent may be withheld in Seller’s sole discretion. Notwithstanding the foregoing, however, Purchaser may (without Seller’s consent but with advance written noticed to Seller) assign and transfer in whole or in part all of its rights and obligations under this Agreement to one (1) or more Affiliates of Purchaser, in the form of the Assignment of Purchase Agreement attached hereto as Exhibit R. Notwithstanding any assignment of its rights hereunder, the assigning purchaser shall remain liable for all obligations of the “Purchaser” hereunder. Any assignment as permitted in the preceding sentence shall be conditioned upon Purchaser delivering to Seller and Escrow Agent, not later than ten (10) days prior to Closing Date, a copy of such assignee’s organizational and formation

WRIT MOB – Transaction II

documents and instruments, a Certificate of Good Standing for such assignee, and a fully-executed copy of the assignment agreement. Seller may not assign or transfer their respective rights or obligations under this Agreement without the prior written consent of Purchaser. No transfer or assignment by either party in violation of the provisions hereof shall be valid or enforceable. Notwithstanding anything to the contrary, and without limiting the foregoing, Purchaser may not assign this Agreement unless, after taking into account all assignments of this Agreement, all Persons who take title to the Property or any portion thereof at Closing are disregarded as separate from no more than one (1) Person for U.S. Federal income tax purposes.

12.6 IRS - Form 1099-S. For purposes of complying with Section 6045 of the Internal Revenue Code of 1986, as amended, Escrow Agent shall be deemed the “person responsible for closing the transaction” and shall be responsible for obtaining the information necessary to file with the Internal Revenue Service Form 1099-S, “Statement for Recipients of Proceeds from Real Estate, Broker and Barter Exchange Transactions.”

12.7 Successors and Assigns. Subject to the provisions of Section 12.5 hereof, this Agreement shall be binding upon and inure to the benefit of the parties’ respective successors and permitted assigns.

12.8 Time is of the Essence. Time is of the essence of this Agreement.

12.9 Entire Agreement. This Agreement and Exhibits and other documents and instruments attached to or referenced herein, contain the entire understanding and agreement between the parties hereto with respect to the purchase and sale of the Property, and all prior and contemporaneous understandings, letters of intent, agreements and representations, whether oral or written, are entirely superseded. Except for any of the following expressly contained in this Agreement, Seller and Purchaser each expressly disclaim any reliance on any oral or written representations, warranties, comments, statements or assurances made by Seller, Purchaser, and any of their respective affiliates, and their respective agents, employees, representatives, attorneys or brokers, as an inducement or otherwise, to Purchaser’s and Seller’s respective execution hereof. No amendment of this Agreement shall be binding unless in writing and executed by the parties hereto.

12.10 Further Assurances. Whenever and so often as requested by a party, the other party will promptly execute and deliver or cause to be executed and delivered all such other and further instruments, documents or assurances, and promptly do or cause to be done all such other and further things as may be necessary and reasonably required in order to further and more fully vest in such requesting party all rights, interests, powers, benefits privileges and advantages conferred or intended to be conferred upon it by this Agreement, or to effectuate the termination of this Agreement and cancellation of the Escrow (if otherwise permitted hereunder). The terms of this section shall survive Closing and/or termination of this Agreement.

12.11 Waiver. Failure or delay by either party to insist on the strict performance of any covenant, term, provision or condition hereunder, or to exercise any option herein contained, or to pursue any claim or right arising herefrom, shall not constitute or be construed as a waiver of such covenant, term, provision, condition, option, claim or right (except that if a party proceeds to Closing,

WRIT MOB – Transaction II

notwithstanding the failure of a condition to its obligation to close, then such condition shall be deemed waived by virtue of the Closing). 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, Seller shall bear the risk of loss resulting from damage to the Property by fire or other casualty (collectively “Casualty”). If, prior to the Closing Date, the Property shall be damaged by any Casualty, Seller shall promptly deliver to Purchaser a Notice (“Casualty Notice”) of such event. Upon Purchaser’s receipt of a Casualty Notice, 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 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 Seller and 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 Seller and one half (1/2) by Purchaser.

12.13.2 Material Loss. If the Casualty Renovation Cost for the Property exceeds five percent (5%) of the Purchase Price, then Purchaser may, at its option, elect to terminate this Agreement. Such termination right may be exercised only by Notice to Seller within ten (10) business days after the date that the Casualty Renovation Cost for the Property 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). 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 Seller shall assign the insurance proceeds to Purchaser and Seller shall pay to Purchaser the amount of any deductible not already otherwise paid by Seller under applicable insurance policies.

12.13.3 Nonmaterial Loss. If the Casualty Renovation Cost for the Property does not exceed five percent (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 Seller 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, Seller receives notice that any portion of the Property (or access or other material rights in connection therewith) as would,

WRIT MOB – Transaction II

in Purchaser’s reasonable judgment, materially adversely affect the operation of the Property or uses of the Property is, or has been threatened in writing by a governmental authority of competent jurisdiction, to be taken by condemnation or eminent domain, 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 the Property, terminate. 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 Seller to Purchaser, and any money theretofore received by 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. 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, or (c) would result in a condemnation award reasonably estimated to exceed five percent (5%) of the Purchase Price.

12.14 Construction of Agreement. The parties hereto have negotiated this Agreement at length, and have had the opportunity to consult with, and be represented by, their own competent counsel. This Agreement is, therefore, deemed to have been jointly prepared. In determining the meaning of, or resolving any ambiguity with respect to, any word, phrase or provision of this Agreement, no uncertainty or ambiguity shall be construed or resolved against any party under any rule of construction, including the party primarily responsible for the drafting and preparation of this Agreement. 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, Seller 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 Seller’s certification of representations and warranties to be delivered at Closing) prior to the Closing Date for which the other party shall have no liability.

WRIT MOB – Transaction II

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 Seller 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, Seller 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 Seller 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 Seller (i) from discussing the Proprietary Information with any person who is employed by Purchaser or Seller or who, on behalf of Purchaser or Seller, is actively and directly participating in the purchase and sale of the Property, 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 Property; provided, however, that if Purchaser or Seller 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 Seller 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 the Property prior to the Closing Date without Seller’s consent, and agrees to be liable for all of the Seller’s 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, Seller 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 Seller and Purchaser and their permitted successors and assigns respectively.

WRIT MOB – Transaction II

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 Seller 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. Seller and/or Purchaser (or a parent entity of Seller or the Purchaser that is recognized as a separate entity for federal income tax purposes) may consummate the sale of the Property 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 Seller or Purchaser elects to effectuate an Exchange, and such Exchange cannot be effected for any reason, the Closing shall not be delayed and Seller 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, the Property, Seller 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.

WRIT MOB – Transaction II

12.22.3 If Seller or Purchaser exercises its right to exchange, rather than sell or purchase, as applicable, the Property, Seller 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 the Property 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 the Property 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 Seller to convey the Property to an Accommodator or an EAT at Closing, subject to all of Seller’s rights and remedies under this Agreement; provided, however, that Seller 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 Seller under this Agreement shall be made to the Accommodator or the EAT and not to Seller. Purchaser and Seller 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.
