 5.      REPRESENTATIONS AND
WARRANTIES.  Seller represents and warrants to Purchaser as follows, which representations and warranties shall also be true and correct in all material respects at Closing: 

5.1      Seller’s Authority For Binding Agreement.  Seller is a duly
authorized and validly existing limited partnership formed under the laws of Delaware, qualified to do business in the Commonwealth of Virginia and in good standing with the Commonwealth of Virginia. Seller has full power, right and authority to own
its properties, to carry on its business as now conducted, and to enter into and fulfill its obligations under this Agreement. Each of the persons or entities executing this Agreement on behalf of Seller is authorized to do so. This Agreement is the
valid and legally binding obligation of Seller, enforceable against Seller in accordance with its terms. The execution and delivery of this Agreement and compliance with its terms will not conflict with or result in the breach of any law, judgment,
order, writ, injunction, decree, rule or regulation, or conflict with or result in the breach of any other agreement, document or instrument to which Seller is a party or by which it or the Property is bound or affected. 

5.2      Employment on “At-Will” Basis.  All persons and
entities presently employed in connection with the operation and maintenance of the Premises are employed on an “at will” basis; are dischargeable upon thirty (30) days notice, and, unless otherwise directed by Purchaser, shall be
terminated by Seller as of Closing. There are no labor disputes pending, nor to the best of Seller’s knowledge, contemplated pertaining to the operation or maintenance of the Premises, or any part thereof. Seller has no employment agreements,
either written or oral, with any person which would require Purchaser to employ any person after the Effective Date. 
 5.3      Service Contracts.  Exhibit C attached hereto is a list of all existing service, equipment, supply and maintenance contracts with respect to
or affecting the Property (the “Service Contracts”). No written notice of default or breach by Seller in the terms of any of such Service Contracts has been received by Seller which has not been cured. Seller has performed, and at
Closing shall have performed, all material obligations which it has under said Service Contracts. 

5.4      Condemnation.  There is no condemnation or eminent domain
proceeding pending with regard to any part of the Property, and to the best of Seller’s knowledge, no such proceedings are proposed. 
 5.5      No Lawsuits.    There are no claims, lawsuits or proceedings pending, or to the best of the Seller’s knowledge, threatened against or
relating to the Property or which could affect the Property, in any court or before any governmental agency, except for actions for possession, damages and or rent, if any, against defaulted tenants as disclosed in Exhibit D. 

5.6      No Tax Assessments.    There are no public
improvements in the nature of off-site improvements, or otherwise, which have been ordered to be made and/or which have not heretofore been assessed, and, to Seller’s knowledge, there are no special or general assessments currently affecting or
pending against the Property, except as set forth in the Title Binder. 

  
 -4-

 5.7      Leases.  Other than
as set forth on Exhibit E, which sets forth a true, complete and correct rent roll for the Property and/or on Exhibit J which includes a list of all Leases for any space at the Property, there are no oral or written leases or rights of
occupancy or grants or claims of right, title or interest in any portion of the Premises that are binding on Seller. 
 5.8      Compliance with Law. 
   5.8.1    Seller has no knowledge, and has not received any written notice alleging, that the Property is in violation of applicable laws, ordinances, orders, rules or
regulations which violations have not been cured. 
   5.8.2    Except as set
forth in the environmental report(s) set forth on Exhibit I (collectively, the “Report”) which have been delivered to Purchaser, to Seller’s knowledge based solely on the Report and any written notices received
thereafter, there are no Hazardous Substances (defined below) and no Hazardous Wastes (defined below) present on the Property including, without limitation, asbestos, flammable substances, explosives, radioactive materials, hazardous wastes, toxic
substances, pollutants, pollution, contaminant, polychlorinated biphenyls (“PCBs”), urea formaldehyde foam insulation, radon, corrosive, irritant, biologically infectious materials, petroleum product, sludge, hazardous or waste
materials. Seller has not been identified in any litigation, administrative proceeding or investigation as a responsible party or potentially responsible party for any liability for clean-up costs, natural resource damages or other damages or
liability for prior disposal or release of Hazardous Substances, Hazardous Wastes or other environmental pollutants or contaminants at the Property, and no lien or superlien has been recorded, filed or otherwise asserted against any real or personal
property of Seller for any clean-up costs or other responses costs incurred in connection with any environmental contamination that is attributable, in whole or in part, to Seller. For purposes of this Agreement, “Hazardous
Substances” means those elements and compounds which are designated as such in Section 101(14) of the Comprehensive Response, Compensation and Liability Act (CERCLA), 42 U.S.C. Section 9601 (14), as amended, all petroleum products
and by-products, and any other hazardous substances as that term may be further defined in any and all applicable federal, state and local laws; and “Hazardous Wastes” means any hazardous waste, residential or household waste, solid
waste, or other waste as defined in applicable federal, state and local laws. To Seller’s actual knowledge (other than as referenced in the Report), there are no underground storage tanks on the Property and no underground storage tank has been
removed from the Property by Seller or to Seller’s actual knowledge, Seller’s predecessor in title. 

5.9      FIRPTA.  Seller is not a “foreign person” as such term
is defined in Section 1445(f)(3) of the Internal Revenue Code of 1954, as amended (the “Code”). 
 Any and all uses of the phrase, “to Seller’s knowledge,” “to Seller’s actual knowledge” or other references to Seller’s knowledge in this Agreement (or in
any other document delivered by Seller pursuant to the terms of this Agreement), shall mean the actual knowledge of Robert O’Brien, who is the Property Manager for the Building, Michael J. Cooper, who is Senior Vice President and

  
 -5-

 
Managing Director of Brandywine Realty Trust and Glen M. Holsinger, who is Vice President of Asset Management of Brandywine Realty Trust (individually, a “Seller Knowledge
Individual,” and together, the “Seller Knowledge Individuals”) and includes those facts of which either such person is actually aware. Neither the actual, present, conscious knowledge of any other individual or entity, nor
the constructive knowledge of any other individual or entity, shall be imputed to any Seller Knowledge Individual. Purchaser agrees that no Seller Knowledge Individual shall have any personal liability under this Agreement. 

Except as expressly set forth in this Agreement, Seller has not made and does not hereby make any representations,
warranties or other statements as to the condition of the Property and Purchaser acknowledges that at Closing it is purchasing the Property on an “AS IS, WHERE IS” basis and without relying on any representations and warranties of any kind
whatsoever, express or implied, from Seller, its agents or brokers as to any matters concerning the Property. Except as expressly set forth in this Agreement, no representations or warranties have been made or are made and no responsibility has been
or is assumed by Seller or by any partner, officer, person, firm, agent or representative acting or purporting to act on behalf of Seller as to the condition or repair of the Property or the value, expense of operation, or income potential thereof
or as to any other fact or condition which has or might affect the Property or the condition, repair, value, expense of operation or income potential of the Property or any portion thereof. The parties agree that all understandings and agreements
heretofore made between them or their respective agents or representatives are merged in this Agreement and the schedules and exhibits hereto annexed, which alone fully and completely express their agreement, and that this Agreement has been entered
into after full investigation, or with the parties satisfied with the opportunity afforded for investigation, neither party relying upon any statement or representation by the other unless such statement or representation is specifically embodied in
this Agreement or schedules or the exhibits annexed hereto. Purchaser acknowledges that Seller has requested Purchaser to inspect fully the Property and investigate all matters relevant thereto and, with respect to the condition of the Property, to
rely solely upon the results of Purchaser’s own inspections or other information obtained or otherwise available to Purchaser, rather than any information that may have been provided by Seller to Purchaser. 

The representations and warranties of Seller set forth in this Agreement are subject to the limitations set forth in this
paragraph. If, prior to the Closing, Purchaser shall obtain knowledge of any information that is contradictory to, and would constitute the basis of a breach of, any representation or warranty on the part of Seller, then, promptly thereafter (and,
in all events, prior to the Closing), Purchaser shall deliver to Seller notice of such information specifying the representation or warranty to which such information relates, and Purchaser further acknowledges that such representation or warranty
will not be deemed breached if Purchaser shall have, prior to the Closing, obtained knowledge of any information that is contradictory to such representation or warranty and shall have failed to disclose to Seller as required hereby and Purchaser
shall not be entitled to bring any action after the Closing based on such representation or warranty. Without limiting the generality of the foregoing, Purchaser shall be deemed to know that any Seller

  
 -6-

 
representation or warranty contained herein is untrue, inaccurate or breached to the extent that (1) Purchaser has actual knowledge of any fact or information which is inconsistent with such
representation or warranty or (2) any Diligence Reports contain provisions inconsistent with any of such representations and warranties. “Diligence Reports” mean the results of any examinations, inspections, investigations,
tests, studies, analyses, appraisals, evaluations and/or investigations prepared by or for or otherwise obtained by or on behalf of Purchaser in connection with the Property, together with the documents and other materials delivered by Seller to
Purchaser including, without limitation, the Diligence Materials. A representation or warranty shall not be deemed to have been breached if the representation or warranty is not true and correct in all material respects as of the Closing by reason
of changed facts or circumstances which (i) pursuant to the terms of this Agreement are permitted to have occurred or (ii) are not within the reasonable control of Seller; provided, however that if a material change in (ii) occurs,
Purchaser shall have the right to terminate this Agreement and be entitled to a return of the Deposit, and the parties shall have no further rights and obligations hereunder, except as expressly set forth herein. 

6.        POSSESSION.  Possession of the Premises is to be given
to Purchaser, subject to the right of tenants under the Leases at the Closing, by delivery of the Deed, and all keys, combinations and security codes at Closing. At such time, all Security Deposits shall be conveyed to Purchaser and remain in place
to secure the tenants’ obligations under the Leases to which they apply. 

7.        PURCHASER’S REVIEW AND APPROVAL OF TITLE AND SURVEY.

   7.1       Title Binder.  Attached as
Exhibit B to this Agreement is a copy of Seller’s title insurance policy. Within ten (10) days after the Effective Date, Purchaser shall secure a current title commitment (the “Title Binder”) from Chicago Title
Insurance Company (the “Title Company”) and provide Seller with a copy of the Title Binder. 

  7.1.1    If Purchaser’s Title Binder identifies any title exceptions or defects in
title which are not acceptable to Purchaser (“Title Objections”), Purchaser shall notify Seller in writing of such Title Objections at least seven (7) days prior to expiration of the Inspection Period Expiration Date and Seller
shall notify Purchaser within two (2) business days after receipt of Purchaser’s notice whether Seller will correct such defects prior to Closing (“Seller’s Notice”). If Seller cures such objections within the
foregoing two (2) business day period, or, if Seller elects to cure such objections but they are not cured within such two (2) business day period, and Seller has commenced curing such objections and thereafter diligently proceeds to
perfect such cure (but in no event beyond forty-five (45) days), then this Agreement shall continue in force and effect, and the Closing Date shall be adjusted accordingly. If Seller does not so notify Purchaser within the time specified,
Seller shall be deemed to have delivered to Purchaser, on the second (2nd) business day after receiving the Title Objections, Seller’s Notice stating that Seller is unwilling to cure the Title Objections. To the extent that Purchaser fails to provide written notice
of a Title Objection, Purchaser shall be deemed to have waived such Title Objection and such Title Objection shall constitute a Permitted Exception. If Seller cannot correct such defects by Closing or chooses not to correct such defects, then
Purchaser may accept title as is without abatement or reduction of Purchase Price or Purchaser may terminate 

  
 -7-

 
this Agreement by written notice to Seller delivered within two (2) business days after actual or deemed receipt of Seller’s Notice and receive a full refund of the Deposit. Purchaser
may object to the status of title at Closing and refuse to close this transaction if an updated title search done prior to Closing reveals: (i) that Seller has failed to remove or cure any exception to title that Seller agreed to remove or cure
pursuant to this Section 7.1.1; or (ii) any material matters other than Permitted Exceptions are placed on the record by Seller prior to Closing, whereupon Purchaser may exercise any and all rights and remedies it may have available to it
pursuant to this Agreement or at law, in equity or otherwise. “Permitted Exceptions” means all title and survey matters with respect to the Premises other than Monetary Liens and any title and/or survey matters that Seller agrees to
cure as aforesaid. Notwithstanding anything set forth in this Agreement to the contrary, whether or not Purchaser objects to the same, Seller shall have an obligation to pay (at or prior to Closing) any amount due in order to satisfy and remove from
record title any mortgages, deeds of trust and liens or encumbrances granted by Seller that secure the payment of money and/or mechanic or materialmen liens arising in connection with work performed by Seller at the Property (the “Monetary
Liens”), and Seller hereby irrevocably authorizes Escrow Agent to deduct from the Purchase Price at Closing the amount necessary to pay off or discharge all such Monetary Liens. In no event shall Seller have any obligation to satisfy,
release and/or remove from record title any mechanic and/or materialmen lien claims arising in connection with any goods or services alleged to have been provided to a Premises tenant where such claim arises in connection with goods or services
ordered or contracted for directly by such tenant. 

7.2      Survey.  Seller has delivered to Purchaser a survey(s) of the
Property, and, Purchaser, may order an updated ALTA survey (the “Survey”), prepared by a duly licensed land surveyor acceptable to Purchaser. To the extent the Survey creates any additional Title Objections pursuant to
Section 7.1, such Title Objections shall be resolved in accordance with the provisions (including the timing) set forth in Section 7.1. 
 7.3      Physical and Financial Inspection.  For a period (the “Inspection Period”) commencing on the Effective Date and expiring at 5:00
P.M. (Washington, DC local time) on December 15, 2011 (“Inspection Period Expiration Date”), Purchaser shall have the right to perform a physical and mechanical inspection, measurement and audit of the Property and an
inspection of all books and records and financial information pertaining thereto. Seller shall reasonably cooperate with Purchaser and shall promptly furnish (or as applicable, make available) to Purchaser the documents set forth on Exhibit F
to this Agreement (to the extent in Seller’s possession or control or in the possession or control of a management company hired by Seller to manage the Property) and such information, materials and documents as Purchaser may reasonably request
(collectively, the “Diligence Materials”) and shall have its accountant available throughout such period to assist in Purchaser’s inspection and review. The inspection, audit and measurement of the Property’s operation,
condition and maintenance shall include, without limitation, such environmental and engineering inspections, reviews and assessments that Purchaser deems appropriate. If Purchaser, at Purchaser’s sole and absolute discretion, shall find such
inspection(s) to be unsatisfactory for any reason whatsoever or if Purchaser determines, for any reason or for no reason whatsoever, not to purchase the Property, Purchaser shall have the right, at its option, to

  
 -8-

 
terminate this Agreement in writing on or before the Inspection Period Expiration Date, and upon such termination, the Deposit shall be immediately refunded to the Purchaser, and thereupon the
parties hereto shall have no further liabilities one to the other with respect to the subject matter of this Agreement (except as otherwise provided in this Agreement to the contrary). Purchaser agrees that it shall not unreasonably interfere with
tenants in performing its inspection; provided, however, Purchaser shall have the right to interview the tenants provided Purchaser has given Seller at least two (2) business days’ prior written notice of such interview and Seller or its
representative shall have the right to be present at such interview(s). The foregoing and any other provision of this Agreement to the contrary notwithstanding, the Purchaser shall not have the right to inspect any Excluded Records.
“Excluded Records” means Seller’s income tax records, documents subject to attorney client privilege, corporate records, records relating to Seller’s selling or financing negotiations, appraisals and/or internal documents
relating to, among other things, the value of the Property. 
 7.4      Entry
and Purchaser Indemnity. In connection with any entry by Purchaser, or its agents, employees or contractors onto the Property, Purchaser shall give Seller reasonable advance notice (which notice may be telephonic) of such entry and shall
conduct such entry and any inspections in connection therewith so as to minimize, to the greatest extent possible, interference with Seller’s business and the business of Seller’s tenants and otherwise in a manner reasonably acceptable to
Seller. Purchaser acknowledges that the premises of certain tenants at the Building contain secured areas and that Purchaser will be required to deliver to Seller the names, addresses and other relevant information pertaining to Purchaser’s
agents, employees and/or contractors desiring to enter such premises. Seller shall use commercially reasonable efforts to provide Purchaser with access to such secured areas at the Building and Purchaser further acknowledges that Purchaser may not
be given access to such secured areas. Without limiting the foregoing, prior to any entry to perform any on-site testing, Purchaser shall give Seller notice thereof (which notice may be telephonic), including the identity of the company or persons
who will perform such testing and the proposed scope of the testing. Seller or its representative may be present to observe any testing or other inspection performed at the Property. Purchaser shall maintain, and shall assure that its contractors
maintain, public liability and property damage insurance in amounts and in form and substance adequate to insure against all liability of Purchaser, its agents, employees or contractors, arising out of any entry or inspections of the Property
pursuant to the provisions hereof, and Purchaser shall provide Seller with evidence of such insurance coverage upon request by Seller. Purchaser shall indemnify, defend and hold Seller harmless from and against any costs, damages, liabilities,
losses, expenses, liens or claims (including, without limitation, reasonable attorney’s fees) arising out of or relating to any entry on the Property by Purchaser, its agents, employees or contractors in the course of performing the
inspections, testings or inquiries provided for in this Agreement, including without limitation damage to the Property or release of hazardous substances or materials onto the Property, excluding, however, the discovery of the existence of any such
hazardous substances, and any costs incurred by Seller in supervising Purchaser’s testing. The foregoing indemnity shall survive beyond the Closing, or if the sale is not consummated, beyond the termination of this Agreement. 

  
 -9-

   7.5      Termination of
Service Contracts. Seller shall terminate, effective as of Closing, at no charge to Purchaser, all Service Contracts that are rejected pursuant to written notice delivered by Purchaser to Seller no later than on the Inspection Period
Expiration Date, but only to the extent such Service Contracts can be terminated by Seller at Closing without payment of any termination payment or penalty and without payment for any post-Closing period. 

8.        SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties of Purchaser and Seller set forth herein shall survive the Closing and delivery of the deed for a period of nine (9) months from the date of Closing (the “Survival Period”). All rights of
Purchaser hereunder or under any of the Closing Documents, with respect to any surviving representation, warranty, covenant or indemnity shall be deemed waived if Purchaser does not, by written notice to Seller, advise Seller of any alleged breach
of representation, warranty or covenant, or any alleged indemnification obligation, prior to the 5:00 P.M. (Washington, DC local time) on the last day of the Survival Period and file suit within sixty (60) days after expiration of the Survival
Period. Subject to the limitation set forth in the immediately preceding sentence, all remedies shall be those set forth in Section 13 below, and notwithstanding anything herein to the contrary, Seller’s liability under any representation,
warranty, covenant or indemnity made hereunder shall in no event exceed the aggregate Seller’s Maximum Liability (as hereinafter defined). The provisions of this Section shall survive the Closing. 

9.        FIRE OR OTHER CASUALTY. 

  9.1      Maintain Insurance.  Seller shall maintain in effect
until the Closing the insurance policies (or like policies) now in effect with respect to the Premises and Personal Property. 
   9.2      Minimal Damage.  If prior to the Closing any portion of the Property is damaged or destroyed by fire or other casualty, and the cost of
repair or restoration thereof shall be $1,000,000.00 or less (as established by good faith estimates obtained by Seller), this Agreement shall remain in force and Seller shall commence to repair any such damage prior to Closing, if possible.

   9.3      Substantial Damage.  If prior to the
Closing any portion of the Property is damaged or destroyed by fire or other casualty, and the cost of repair or restoration thereof shall be more than $1,000,000.00 (as established by good faith estimates obtained by Purchaser), Purchaser may
within thirty (30) days after receipt of notice (“Damage Notice”) of said damage or destruction, terminate this Agreement by giving written notice thereof to Seller (“Purchaser’s Notice of Election”), and
if this Agreement is so terminated, then the Deposit shall be immediately refunded to Purchaser, and thereafter neither party shall have any further liability hereunder thereafter. If Purchaser does not so terminate this Agreement, it shall remain
in full force and effect, and the provisions of Section 9.4 below shall apply. 

  9.4      Closing After Substantial Damage. So long as this
Agreement shall remain in force under Section 9.2 or 9.3, then (i) all proceeds of insurance collected prior to Closing, plus the 

  
 -10-

 
amount of deductible under Seller’s insurance policy, shall be adjusted subject to Purchaser’s reasonable approval and participation in any adjustment, and shall be credited to
Purchaser against the Purchase Price payable by Purchaser at Closing, and (ii) all unpaid claims and rights in connection with losses shall be assigned to Purchaser at Closing. 

10.      CONDEMNATION.  If, prior to the Closing, all or any portion of
the Premises is taken by eminent domain or a notice of any eminent domain proceedings with respect to the Premises or any part thereof is received by the Seller, then Seller shall within five (5) days thereafter give notice thereof to Purchaser
and Purchaser shall have the option to (a) complete the purchase hereunder or (b) if such taking, in Purchaser’s sole and absolute discretion, adversely affects the Premises or its current economic viability, terminate this Agreement,
in which event the Deposit shall be immediately refunded to Purchaser, and this Agreement shall be null and void. Purchaser shall deliver written notice of its election to the Seller within twenty (20) days after the date upon which the
Purchaser receives written notice of such eminent domain proceedings. If notice of condemnation is received by Purchaser and it fails to deliver said written notice of its election within said time period, such failure shall constitute a waiver by
Purchaser of its right to terminate this Agreement. If this Agreement is not so terminated and there is no adjustment of the Purchase Price, Purchaser shall be entitled to all awards or damages by reason of any exercise of the power of eminent
domain or condemnation with respect to or for the taking of the Premises or any portion thereof, and until such time as Closing has occurred, or this Agreement terminates. Any negotiation for, or agreement to, and all contests of any offers and
awards relating to eminent domain proceedings shall be conducted with the joint reasonable approval and consent of the Seller and the Purchaser. 
 11.      EXPENSE ALLOCATIONS. 
   11.1    Seller and Purchaser shall each pay one-half (1/2) of the Grantor’s Tax and shall each pay one-half (1/2) of the Recordation Tax upon the recording
of the Deed.

12.3    Conditions to Closing. The following shall be a conditions precedent to
Purchaser’s obligation to consummate the Closing which conditions, if not satisfied prior to Closing, shall permit Purchaser to terminate this Agreement and receive a refund of its Deposit hereunder: 

12.3.1 Seller shall deliver title to the Premises in the condition in which Seller is required to deliver title under
Section 7; 
 12.3.2 All of the representations and warranties of Seller contained in this Agreement (as
modified by the terms of this Agreement) shall be true and correct in all material respects on the Closing Date as if the same were made on and as of such date; 

12.3.3 All covenants and obligations of Seller required in this Agreement to be performed on or before the Closing have
been timely and duly performed in all material respects; and 
 12.3.4 Seller shall have delivered to Purchaser
either an original or an electronic copy (with an original to follow upon receipt by Seller) of the TWC Estoppel at least three (3) business days prior to Closing and such TWC Estoppel shall satisfy the applicable provisions set forth in
Section 12.4. 
 12.4    Tenant Estoppel Certificates. The “TWC
Estoppel” means a written statement (a “Tenant Estoppel Certificate”) signed by Time Warner Cable Inc. in substantially the form attached to this Agreement as Exhibit G, which TWC Estoppel shall not disclose any
information that directly and materially deviates from the information set forth in the rent roll attached hereto as Exhibit J and shall not disclose any default under the Lease. The fact that a Tenant Estoppel Certificate (whether the TWC
Estoppel or any other Tenant Estoppel Certificate) addresses matters not addressed in the rent roll attached hereto as Exhibit J shall not be deemed to constitute a material deviation from the information set forth in the rent roll
(e.g., a Tenant Estoppel Certificate might address tenant improvement allowances and the rent roll might be silent on such issue). Seller agrees to use commercially reasonable efforts to cause all of the other tenants under the Leases to
deliver to Purchaser at Closing a Tenant Estoppel Certificate in substantially the form attached to this Agreement as Exhibit G; provided, however, that if any Lease requires the tenant thereunder to submit a particular form of tenant
estoppel certificate to its landlord, then such tenant 

  
 -14-

 
may submit the form of tenant estoppel certificate required by its Lease, in lieu of the form of Tenant Estoppel Certificate attached to this Agreement as Exhibit G. Seller’s failure
to obtain a Tenant Estoppel Certificate from Time Warner Cable Inc. and/or from any particular tenant(s) under any applicable Lease(s) shall not constitute a default under this Agreement, provided Seller has used commercially reasonable efforts to
obtain a Tenant Estoppel Certificate from Time Warner Cable Inc. or such other tenant(s). 

13.    DEFAULT; REMEDIES. 

13.1    Seller Default. If, subject to the provisions of the last paragraph of
Section 5, Seller fails to timely perform any of its obligations under this Agreement in any material respect (a “Seller Default”), Purchaser may, at its option, terminate this Agreement by giving written notice of such
termination to Seller and Escrow Agent shall immediately thereafter return the Deposit, and thereupon, subject to the provisions of Section 13.3 below, the parties shall have no further liability to each other hereunder except for those
provisions that expressly survive Closing or the termination of this Agreement. In the alternative, upon the occurrence of a Seller Default, Purchaser may seek to enforce specific performance of this Agreement provided that any action for specific
performance shall be commenced within thirty (30) days after the scheduled date for Closing. If Purchaser fails to commence an action for specific performance within such period, Purchaser’s sole remedies shall be to receive a return of
the Deposit and reimbursement of Purchaser’s Transaction Costs. 

13.2    Purchaser Default. If Purchaser fails to timely perform any of its obligations under
this Agreement in any material respect, Seller’s sole remedy shall be to retain the Deposit as liquidated damages. 
 13.3    Purchaser’s Out-of-Pocket Costs. In the event of Seller Default hereunder which results in Purchaser’s termination of this Agreement, or in the event that
Seller shall fail to perform any term, covenant or agreement, then, in any such event, upon termination by Purchaser hereunder, in addition to receiving the immediate return of the Deposit, anything in the Agreement contained to the contrary
notwithstanding, Purchaser shall also receive from Seller, upon demand, Purchaser’s actual, documented out-of-pocket costs and expenses associated with this Agreement and Purchaser’s anticipated acquisition of the Property including,
without limitation, Purchaser’s reasonable counsel fees and costs, title expenses, survey costs, and other costs and expenses associated with Purchaser’s due diligence, including, without limitation, legal, financial and accounting due
diligence, Purchaser’s structural inspection of the Property and Purchaser’s environmental assessment of the Property (collectively, “Transaction Costs”). The foregoing list is not intended to be exclusive, but
representative of the costs and expenses that the parties anticipate that Purchaser will incur in anticipation of this transaction. Seller’s maximum reimbursement liability for the Transaction Costs under this Section 13.3 shall not exceed
Fifty Thousand and No/100 Dollars ($50,000.00). NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE CONTRARY, SELLER’S TOTAL LIABILITY FOR DAMAGES FOR BREACH OF THE COVENANTS, AGREEMENTS, WARRANTIES AND REPRESENTATIONS UNDER THIS
AGREEMENT TO THE EXTENT PURCHASER 

  
 -15-

 
CLOSES HEREUNDER, COLLECTIVELY, SHALL NEVER EXCEED TWO MILLION DOLLARS ($2,000,000.00) (THE “SELLER’S MAXIMUM LIABILITY”), AND IN NO EVENT SHALL SELLER BE LIABLE FOR SPECIAL,
EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES. 
 14.    PRORATIONS. 

14.1    Operating Expenses. The following items shall be prorated at Closing, as of 12:01
a.m. (Washington, DC local time) on the date of Closing on a per diem basis (the “Adjustment Date”): 
 14.1.1 Rents and Taxes. Rents, operating expenses, real estate and personal property taxes, if any, on the basis of the fiscal year for which assessed. 

14.1.1.1 If the Closing shall occur before the tax rate or assessment is fixed, the apportionment of such real estate
and personal property taxes at the Closing shall be upon the basis of the tax rate for the next preceding year applied to the latest assessed valuation. Final adjustment will be made upon the actual tax amount, when determined. 

14.1.1.2 All rents and other sums received from tenants of the Property, which were earned and attributable to the
period prior to the Closing Date, will be retained by Seller to the extent that such rents have been collected on or before the Closing. Rents earned and attributable to the period beginning on the Closing Date and thereafter will be paid to
Purchaser by the tenants, or credited to Purchaser at Closing. All payments from tenants, on account of rent or otherwise, received by Seller after the Closing, whether attributable to the period prior to or after the Closing, shall be promptly
delivered to Purchaser for application as provided in Section 14.1.1.3. 
 14.1.1.3 All payments from
tenants, on account of rent or otherwise, received after the Closing by Purchaser and all amounts received from Seller by Purchaser pursuant to the immediately preceding sentence, shall be applied first to rent or other sums then due under the
Leases attributable to the period beginning on the Closing Date and continuing thereafter, and then to payment to Seller on account of rents which were earned and attributable to the period prior to the Closing but which were not paid when due. Any
reasonable out-of-pocket third-party costs incurred by Purchaser in collection of delinquent rentals shall be deducted by Purchaser prior to the payment to Seller on account of delinquent rentals as provided herein. Purchaser shall use commercially
reasonable efforts to collect or attempt to collect pre-closing delinquent rentals, provided, however, Purchaser shall not be required to declare any tenant to be in default under its Lease in connection therewith. 

14.1.2 Deposits. Tax and utility company deposits, if any. 

14.1.3 Water and Sewer Charges. Water and sewer charges and fire protection and inspection services based
upon meter readings to be obtained by Seller effective as of the Adjustment Date, or if not so obtainable, a date not more than ten (10) days prior to the Adjustment 

  
 -16-

 
Date, and the unfixed meter charges based thereon for the intervening period shall be apportioned on the basis of such last reading. Upon the taking of a subsequent actual reading, such
apportionment shall be readjusted and Seller or Purchaser, as the case may be, will promptly deliver to the other the amount determined to be so due upon such readjustment. If Seller is unable to furnish such prior reading, any reading subsequent to
the Closing will be apportioned on a per diem basis from the date of such reading immediately prior thereto and Seller shall pay the proportionate charges due up to the date of Closing. 

14.1.4 Assigned Contracts.  Amounts paid or payable in respect of any Service Contracts assigned to
Purchaser if not otherwise terminated in accordance herewith. 
 14.1.5 Electricity, gas, steam and
fuel. Electricity, gas and steam and fuel oil, if any, based on meter readings or a fuel company letter showing measurement on the day immediately preceding Closing, and valued at current prices. 

14.1.6 Leasing Commissions and Tenant Improvement Costs. Any provision of this Agreement to the contrary
notwithstanding, Seller shall be responsible for any unpaid tenant improvement allowances and unpaid leasing commissions with respect to any Lease executed prior to the Closing (except as provided below), but only to the extent such allowances and
commissions relate to both the current lease term and the current leased premises (“Lease Expenses”) (whether one or more, the “Seller’s Capital Lease Obligations”), as more fully described on Exhibit H)
and not to any future lease term renewal(s) or future premises expansion(s). Purchaser and Seller shall allocate the amounts payable by Seller under the Seller’s Capital Lease Obligations as aforesaid in a manner mutually acceptable to them, in
the form of an adjustment at Closing. 
 14.1.7 Security Deposits.   All cash Security
Deposits under the Leases (together with any accrued interest thereon as may be required by law or contract) shall be credited to Purchaser as of the Closing Date. 

14.2    Custom and Practice. Except as set forth in this Agreement, the customs of the State
and County in which the Premises are located shall govern prorations. 
 14.3    Future
Installments of Taxes. If at Closing, the Property or any part thereof shall be or shall have been affected by an assessment or assessments which are or may become payable in installments, then for purposes of this Agreement, all unpaid
installments of any such assessment, including those which are to become due and payable and to be liens upon the Property shall be adjusted to the Adjustment Date. 

14.4    Application of Prorations.   If such prorations result in a payment
due Purchaser, the cash payable at Closing shall be reduced by such sum. If such prorations result in a payment due Seller, the same shall be added to the sales proceeds at Closing. 

  
 -17-

 14.5    Schedule of Prorations. Seller and
Purchaser shall work together to jointly prepare a schedule of prorations for the Property no less than five (5) days prior to Closing. 
 14.6    Readjustments. The parties shall correct any errors in prorations as soon after the Closing as amounts are finally determined. 

14.7    Survival. It is agreed that adjustment billings to tenants for operating expenses,
common area maintenance charges, taxes or insurance premiums for the accounting year in which the Closing occurs shall be billed by Purchaser and shall be adjusted between Seller and Purchaser based upon the respective percentages of the total
related expenses paid by each of Purchaser and Seller for such accounting year. To satisfy Purchaser’s foregoing obligation to bill tenants for the full calendar year 2011, within thirty (30) days following Closing, Seller shall provide
Purchaser with general ledgers for calendar year 2011 through the Closing Date. Notwithstanding the foregoing, each of the provisions of this Section 14 shall survive the Closing and delivery of the deed for a period of six (6) months from
the Closing Date and all adjustments and prorations shall become final and no further adjustments or prorations shall be done (except that all prorations and allocations relating to operating expenses, common area maintenance charges, taxes or
insurance premiums charges shall be final 150 days following the end of calendar year 2011). 

15.    BROKERS. Except for Cassidy Turley’s fee, which shall be paid by Seller pursuant
to a separate agreement with such broker, each party hereby represents and warrants to the other that it has not employed or retained any broker or finder in connection with the transactions contemplated by this Agreement, and that neither has had
any dealings with any other person or party which may entitle that person or party to a fee or commission. Each party shall indemnify the other of and from any claims for commissions by any person or party claiming such commission by or through the
indemnifying party. 
 16.    ESCROW AGENT.  The parties hereto have
requested that the Deposit be held in escrow by the Escrow Agent to be applied at the Closing or prior thereto in accordance with this Agreement. The Escrow Agent will deliver the Deposit to Seller or to Purchaser, as the case may be under the
following conditions: 
 16.1    Payment to Seller. To Seller upon the consummation
of Closing. 
 16.2    Payment to a Party. To a party as specified in a document
signed by Seller and Purchaser or their attorneys. 
 16.3    Notice of Dispute. If
either Seller or Purchaser believes that it is entitled to the Deposit or any part thereof, it shall make written demand therefor upon the Escrow Agent. The Escrow Agent shall promptly mail a copy thereof to the other party in the manner specified
in Section 17.1 below. The other party shall have the right to object to the delivery of the Deposit, by filing written notice of such objections with the Escrow Agent at any time within ten (10) days after the mailing of such copy to it
in the manner specified in Section 17.1 below, but not thereafter. Such 

  
 -18-

 
notice shall set forth the basis for objection to the delivery of the Deposit. Upon receipt of such notice, the Escrow Agent shall promptly deliver a copy thereof to the party who filed the
written demand. 
 16.4    Escrow Subject to Dispute. In the event the Escrow Agent
shall have received the notice of objection provided for in 16.3 above of this Section, in the manner and within the time therein prescribed, the Escrow Agent shall continue to hold the Deposit until (i) the Escrow Agent receives written notice
from both Seller and Purchaser directing the disbursement of the Deposit in which case the Escrow Agent shall then disburse said Deposit in accordance with said direction, or (ii) litigation arises between Seller and Purchaser, in which event
the Escrow Agent shall deposit the Deposit with the Clerk of the Court in which said litigation is pending, or (iii) the Escrow Agent takes such affirmative steps as the Escrow Agent may, at the Escrow Agent’s option elect in order to
terminate the Escrow Agent’s duties including, but not limited to, deposit in Court and an action for interpleader. 
 16.5    Escrow Agent’s Rights and Liabilities. Escrow Agent shall not be required to determine questions of fact or law, and may act upon any instrument or other writing
believed by it in good faith to be genuine and to be signed and presented by the proper person, and shall not be liable in connection with the performance of any duties imposed upon Escrow Agent by the provisions of this Agreement, except for Escrow
Agent’s own willful default or gross negligence. Escrow Agent shall have no duties or responsibilities except those set forth herein. Escrow Agent shall not be bound by any modification of this Agreement, unless the same is in writing and
signed by Purchaser and Seller, and, if Escrow Agent’s duties hereunder are affected, unless Escrow Agent shall have given prior written consent thereto. In the event that Escrow Agent shall be uncertain as to Escrow Agent’s duties or
rights hereunder, or shall receive instructions from Purchaser or Seller which, in Escrow Agent’s opinion, are in conflict with any of the provisions hereof, Escrow Agent shall be entitled to hold and apply the Deposit, pursuant to
Section 16.3, and may decline to take any other action. 
 17.    GENERAL

FORM OF AUDIT LETTER 
  

			
	[Auditor]	 	
	  
	 	
	  
	 	

 Dear Sirs: 
 We are writing at your request to confirm our understanding that your audit of the Statement of Revenue and Certain Expenses for the year ended
                    , 20   , was made for the purpose of expressing an opinion as to whether the statement of operating
income presents fairly, in all material respects, the results of operations of 13820 Sunrise Valley Drive, Herndon, Fairfax County, Virginia 20171 in conformity with generally accepted accounting principles. 

Certain representations in this letter are described as being limited to matters that are material. Items are considered material if they
involve an omission or misstatement of accounting information that, in light of surrounding circumstances, makes it probable that the judgment of a reasonable person relying on the information would be changed or influenced by the omission or
misstatement. An omission or misstatement that is monetarily small in amount could be considered material as a result of qualitative factors. 
 The following representations are made exclusively to the auditor of the Project. In connection with your December 31, 20    audit we confirm, to the best of our knowledge and
belief, with respect to our daily operations and without independent inquiry or investigation, the following representations made during your audit: 
 1.      We have made available to you all financial records and related data concerning this Project, which are in our possession. 

2.      We are not aware of any: 

 

	 	 a.	Irregularities involving any member of management or employees that could have a materially adverse effect on the statement of operating income.

  

	 	 b.	Notices of violations of laws or regulations, the effects of which should be considered for disclosure in the financial statements or as a basis for recording a loss
contingency. 

  

	 	 c.	Material events that have occurred subsequent to                   ,
20    that would require material adjustment to the statement of operating income. 

3.      There are no material transactions that have not been properly recorded in the accounting records
underlying the financial statements. 
 [Appropriate signature line]
