this Agreement. If Purchaser fails to timely deposit the Deposit with Escrow Agent, this Agreement shall terminate and be of no force and effect. 
 Section 2.6.    Escrow Agent. 

(a)      Seller and Purchaser hereby appoint Escrow Agent as escrow agent to hold, administer and disburse
the Deposit. Escrow Agent accepts such appointment and agrees to hold, invest and disburse the Deposit in accordance with the terms of this Agreement. Upon receipt of the Deposit, Escrow Agent shall give written notice of such receipt to Purchaser
and Seller. In the event that Escrow Agent does not receive the Deposit on or before the date two (2) business days after the Effective Date, Escrow Agent shall so notify Purchaser and Seller in writing. 

  
 8 

 (b)      The Escrow Agent shall hold the Deposit in an
interest-bearing, money market account with Wells Fargo Bank, N.A., in accordance with the terms and conditions of this Agreement. All interest or other income on such sum shall be the sole and exclusive income and property of Purchaser and shall be
disbursed to Purchaser at any time or from time to time as Purchaser shall direct Escrow Agent. Such interest or other income shall not be deemed a part of the Deposit. Purchaser’s Federal Identification Number is 27-1317476. 

(c)      At such time as Escrow Agent receives written notice from either Purchaser or Seller, or both,
setting forth the identity of the party to whom such Deposit (or portions thereof) is to be disbursed and further setting forth the specific section or paragraph of this Agreement pursuant to which the disbursement of such Deposit (or portions
thereof) is being requested, Escrow Agent shall disburse such Deposit pursuant to such notice; provided, however, that if such notice is given by either Purchaser or Seller but not both, Escrow Agent shall (i) promptly notify the other party
(either Purchaser or Seller as the case may be) that Escrow Agent has received a request for disbursement, and (ii) withhold disbursement of such Deposit for a period of ten (10) days after Escrow Agent notifies such other party of the
disbursement request and if Escrow Agent receives written notice from either Purchaser or Seller within said ten (10) day period which notice countermands the earlier notice of disbursement, then Escrow Agent shall withhold such disbursement
until both Purchaser and Seller can agree upon a disbursement of such Deposit. Purchaser and Seller hereby agree to send to the other, pursuant to Section 11.4 below, a duplicate copy of any written notice sent to Escrow Agent and
requesting any such disbursement or countermanding a request for disbursement. 
 (d)      Seller
and Purchaser agree that the duties of the Escrow Agent hereunder are purely ministerial in nature and shall be expressly limited to the safekeeping and disposition of the Deposit in accordance with this Agreement. Escrow Agent shall incur no
liability in connection with the safekeeping or disposition of the Deposit for any reason other than Escrow Agent’s willful misconduct or default, breach of trust, or gross negligence. In the event that Escrow Agent shall be in doubt as to its
duties or obligations with regard to the Deposit, or in the event that Escrow Agent receives conflicting instructions from Purchaser and Seller with respect to the Deposit, Escrow Agent shall not be required to disburse the Deposit and may, at its
option, continue to hold the Deposit, until both Purchaser and Seller agree as to its disposition, or until a final judgment is entered by a court of competent jurisdiction directing its disposition, or Escrow Agent may interplead the Deposit in
accordance with the laws of the state in which the Property is located. 
 (e)      Escrow Agent
shall not be responsible for any interest on the Deposit except as is actually earned, or for the loss of any interest resulting from the withdrawal of the Deposit prior to the date interest is posted thereon. 

(f)      Purchaser and Seller hereby agree to indemnify and hold Escrow Agent harmless against any and all
losses, claims, damages, liabilities, and expenses, including, without limitation, reasonable costs of investigation and legal counsel fees, which may be imposed upon Escrow Agent or incurred by Escrow Agent in connection with the performance of its
duties hereunder, including, without limitation, any litigation arising from this Agreement or involving the subject matter hereof; provided, however, that Escrow Agent is not indemnified for any such losses, claims, damages, liability and/or
expenses that rise in part or in whole out of Escrow Agent’s willful misconduct or default, breach of trust or gross negligence. 

  
 9 

 (g)      Escrow Agent shall execute this Agreement solely for
the purpose of being bound by the provisions of Section 2.5, Section 2.6, Section 6.4(b), Section 7.1 and Section 7.2 hereof. 

Section 2.7.    Independent Contract Consideration.    In addition to, and not in

at Closing. 
 ARTICLE III  
 TITLE AND SURVEY 

Section 3.1.    Title and Survey Review. 

(a)      The Property shall be transferred by Seller to Purchaser subject to all of the following matters,
which are hereinafter referred to collectively as the “Permitted Exceptions”: 

(i)       those matters described in Exhibit C attached hereto;

 (ii)      the rights of Tenants under the Leases; 

(iii)     the lien of all ad valorem real estate taxes and assessments for the year of Closing
not yet due and payable as of the Closing Date, subject to adjustment as herein provided; 

(iv)     local, state and federal laws, ordinances or governmental regulations, including but
not limited to, building and zoning laws, ordinances and regulations, now or hereafter in effect relating to the Property; and 
 (v)      items shown on the New Survey. 

(b)     Fidelity National Title Insurance Company (the “Title Company”) has delivered to
Purchaser, at Seller’s expense, its commitment (hereinafter referred to as the “Title Commitment”) to issue to Purchaser upon the recording of the Special Warranty Deed conveying title to the Land and Improvements from
Seller to Purchaser, the payment of the Purchase Price, and the payment to the Title Company of the policy premium therefor, a TLTA (Form T-1) owner’s policy of title insurance, in the amount of the Purchase Price, insuring good and
marketable fee simple record title to the Property to be in Purchaser without exception 

  
 10 

 
(including any standard exception) except for the Permitted Exceptions. The most recent effective date of the Title Commitment is February 21, 2011 (the “Record Date”) and
was issued on March 23, 2011. Seller has delivered, at Seller’s expense, the most recent surveys of the Real Property prepared by Pacheco-Koch Consulting Engineers, bearing the certification and seal of Michael C. Clover, Registered
Professional Land Surveyor No. 5225 (collectively, the “Existing Survey”). Purchaser has obtained, at Purchaser’s expense, surveys of the Real Property prepared by Benchmark Group of Texas, Inc., bearing the certification
and seal of Bernard Henderson, Registered Professional Land Surveyor No. 5116 (the “New Survey”). The New Survey was most recently updated on March 28, 2011 (the “Survey Date”). Subject to this
Section 3.1(b), Purchaser hereby accepts the Title Commitment, the Existing Survey and the New Survey and all title exceptions set forth in Schedule B of the Title Commitment and survey matters set forth in the Existing Survey and the
New Survey and waives any and all objections to title and survey matters with respect to the Real Property existing as of the Record Date, with regard to the Title Commitment, and the Survey Date, with regard to the Existing Survey and the New
Survey. From the Effective Date until the Closing Date, Purchaser may request an update to the effective date of such Title Commitment (the “Updated Commitment”) or may update the date of the New Survey (the “Updated
Survey”) and, within three (3) days of delivery of any such update, shall give notice to Seller of all defects or objections first appearing subsequent to the Record Date, with respect to the Title Commitment, or the Survey Date, with
respect to the New Survey (the “Subsequent Exceptions”). Such matters as are disclosed by the Updated Commitment and/or the Updated Survey and not timely objected to by Purchaser shall be deemed to be additional “Permitted
Exceptions;” provided, however, that encumbrances created by Seller after the Record Date in violation of this Agreement, taxes due and payable prior to Closing (except those, if any, to be prorated as provided in this Agreement),
and any mortgages, deeds of trust and mechanic’s or materialmen’s liens entered into or created by Seller subsequent to the Record Date shall in no event be deemed to be Permitted Exceptions. Purchaser shall promptly provide to Seller
copies of any Updated Commitment or Updated Survey obtained by, or on behalf of, Purchaser. 
 Seller shall have three
(3) business days after receipt of such notice of a Subsequent Exception from Purchaser to advise Purchaser in writing which of such title defects or objections Seller intends to satisfy or cure; provided, however, that Seller
hereby agrees that Seller shall satisfy or cure prior to Closing any Subsequent Exceptions consisting of encumbrances created by Seller in violation of this Agreement, any taxes due and payable prior to Closing (except those, if any, to be prorated
as provided in this Agreement), and any mortgages, deeds of trust and mechanic’s or materialmen’s liens entered into or created by Seller subsequent to the Record Date. In the event Seller fails to give such written advice to Purchaser
within such three (3) business day period, Seller shall be deemed to have elected not to satisfy or cure any such defects or objections set forth in Purchaser’s notice. If Seller shall advise Purchaser in writing that Seller does not
intend to satisfy or cure any specific Subsequent Exceptions (which Seller is not otherwise obligated to satisfy or cure under this Section 3.1(b)), or if Seller is deemed to have elected not to cure any such Subsequent Exception,
Purchaser may elect either (a) to terminate this Agreement by written notice to Seller within three (3) business days after receipt of notice from Seller (or the end of the 3-day period described above if Seller fails to respond), in which
event the Deposit shall be immediately refunded to Purchaser and this Agreement shall be of no further force or effect and Purchaser and Seller shall have no further rights, obligations or liabilities hereunder, except for the obligations hereunder
which expressly survive termination, 

  
 11 

 
or (b) to accept title subject to such specific Subsequent Exceptions, in which case such specific Subsequent Exceptions shall become additional “Permitted Exceptions.” Seller
shall have until Closing to satisfy or cure all Subsequent Exceptions which Seller agreed to satisfy or cure as provided above. In the event Seller fails or refuses to cure any Subsequent Exceptions which are required herein to be satisfied or cured
by Seller prior to the Closing, then, at the option of Purchaser, (i) Purchaser may terminate this Agreement by written notice to Seller within five (5) days after the scheduled Closing Date, in which event the Deposit shall be immediately
refunded to Purchaser, and this Agreement shall be of no further force and effect and Purchaser and Seller shall have no further rights, obligations or liabilities hereunder, except for the obligations which expressly survive termination,
(ii) if any such Subsequent Exception is one that Seller agreed to satisfy or cure as provided above, Seller shall be in default hereunder and Purchaser shall be entitled to the remedies for default set forth herein, or Purchaser may cure such
Subsequent Exception, in which event the Purchase Price payable pursuant to Section 2.3 hereof shall be reduced by an amount equal to the actual reasonable cost and expense incurred by Purchaser in connection with the curing of such
Subsequent Exception and upon such curing, the Closing hereof shall proceed in accordance with the terms of this Agreement, (iii) Purchaser may accept title to the Property subject to such Subsequent Exception, or (iv) any combination of
items (ii) and (iii). In the event Purchaser elects to cure any such Subsequent Exceptions pursuant to item (ii) hereof, Purchaser at its option, upon giving notice to Seller, may extend the date of Closing until the date which is ten
(10) days after the curing of such Subsequent Exceptions or thirty (30) days from and after the last date set forth in Section 5.1 hereof for Closing, whichever shall first occur. If any Subsequent Exception shall not have been
cured within such period, Purchaser may exercise its option under either item (i) or (iii) hereof. 

Section 3.2.      Conveyance of Title.  At Closing, Seller shall convey and transfer
to Purchaser fee simple record title (such that the Title Company will insure such title) to the Land and Improvements, by execution and delivery of the Special Warranty Deed, free and clear of all liens, easements, restrictions, and
encumbrances whatsoever, excepting only the Permitted Exceptions and such other matters as may become additional “Permitted Exceptions” as provided in Section 3.1(b) above. 

ARTICLE IV  
 REVIEW OF PROPERTY 

Section 4.1.      Deliveries; Property Information. 

(a)      Purchaser acknowledges that, prior to the Effective Date hereof, Seller has made available to
Purchaser (via electronic data room, at the Property or otherwise) all of the information with respect to the Property listed in Exhibit D attached hereto and made a part hereof (the “Deliveries”) and that Purchaser has
had an opportunity to review said Deliveries and waives all objections it might have to all such Deliveries. 

(b)      At all reasonable times prior to the Closing, to the extent in Seller’s possession and

matters, tenant files, as built plans and specifications, engineering reports, reports of insurance carriers insuring the Property, and other contracts, books, records, operating statements, and other information relating to the Property requested
by Purchaser, but excluding Seller’s existing management agreement, company records, internal memoranda, financial projections, budgets, appraisals, accounting and income tax records and similar proprietary, confidential or privileged
information. 
 Section 4.2.    Right of Inspection. 

(a)      As used in this Agreement, the term “Inspections” means entry on the Property to
conduct due diligence, inspections and tests, including architectural, engineering, geotechnical and environmental inspections and tests, subject to the limitations set forth in this Section 4.2. 

(b)      From and after the Effective Date and until the earlier to occur of termination of this Agreement
or Closing, Purchaser and its agents, representatives, contractors and consultants (collectively the “Purchaser Parties”) shall, upon not less than 24 hours prior notice to Seller (which notice may be telephonic), have the right to
enter upon the Property for further onsite inspections during regular business hours (or other hours as shall be approved by Seller in its reasonable discretion) for the purpose of conducting such Inspections as Purchaser may reasonably require. In
exercising such rights, Purchaser and the Purchaser Parties shall use commercially reasonable efforts not to interfere unreasonably with the use of the Property by Seller or the Tenants. Seller shall have the opportunity to have one of its
representatives accompany Purchaser Parties on each such entry. Any and all Inspections shall be done at Purchaser’s sole cost and expense. As part of the Inspections, the Purchaser Parties may meet with or contact building officials,
governmental officials, zoning administrators and other representatives of governmental authorities, parties to service contracts and other agreements, property management personnel and conduct one or more walk throughs of the Property; provided
that Seller shall be given a reasonable opportunity to participate in any of the foregoing. No Inspections shall be physically invasive (unless Purchaser obtains Seller’s prior written consent, which Seller agrees not to unreasonably condition,
delay or withhold), and in any event, the Inspections shall be conducted substantially in accordance with standards customarily employed in the industry and in compliance with all governmental laws, rules and regulations. Following each such entry
by any of the Purchaser Parties with respect to the Inspections, Purchaser shall promptly restore, or cause to be restored, the Property to substantially the same condition as existed prior to any such Inspections (excluding any damage arising out
of the discovery of existing environmental or physical conditions). Purchaser shall not contact the Tenants about the Property without obtaining Seller’s prior written consent (not to be unreasonably withheld), and shall not disrupt any
Tenant’s activities on the Property; provided if Seller so consents to any such contact with the Tenants, Seller shall have the right to participate in such contact and attend any meetings with the Tenants. Seller shall reasonably cooperate in
good faith with Purchaser in its Inspections, but shall not be obligated to incur any liability or expense in connection therewith other than di minimis expenses. 

  
 13 

 (c)      Purchaser agrees to protect, indemnify, defend and
hold Seller harmless from and against any claim for liabilities, losses, costs, expenses (including reasonable attorneys’ fees actually incurred), damages or injuries arising out of or resulting from the Inspections whether occurring prior to
or after the Effective Date, and notwithstanding anything to the contrary in this Agreement, such obligation to indemnify and hold harmless Seller shall survive Closing or any termination of this Agreement; provided, however, that such indemnity
shall not extend to claims or liabilities arising out of the discovery of any existing environmental or physical conditions. In order further to protect Seller from any such losses, costs, expenses, damages or injuries, Purchaser agrees that it will
deliver to Seller and will cause each of the Purchaser Parties to deliver to Seller, prior to their respective entry, a certificate of liability insurance, showing Seller as additional insured and complying with the coverage and policy provisions
specified on the insurance schedule attached hereto as Exhibit T. 
 (d)      All
third-party reports, evaluations, tests, studies and surveys (including without limitation environmental surveys) received or procured by Purchaser from any of its agents or consultants in connection with hazardous materials or substances, wetlands,
flood plain or other environmental conditions at the Property or which relate to the physical condition of the Property shall be submitted to Seller, at no cost to Seller or Purchaser, within ten (10) days after any termination of this
Agreement, provided that (i) Seller is not in default of its representations, warranties and other obligations hereunder and (ii) delivery of such documents, reports, evaluations, tests, studies, surveys and information shall be without
warranty or representation whatsoever, express or implied, including, without limitation, any warranty or representation as to the ownership, adequacy or completeness thereof or otherwise, which disclaimer shall survive the termination of this
Agreement. 
 (e)      Upon termination of this Agreement other than by reason of default of
Seller, if requested by Seller, Purchaser shall promptly execute and deliver to Seller an instrument in recordable form that disclaims any and all continuing right, title and interest in and to the Property and deliver to Seller the reports referred
to in Section 4.2(d). 
 (f)      Purchaser acknowledges that prior to the Effective
Date and pursuant to the terms and conditions of that certain Access Agreement dated February 24, 2011 between Seller and Purchaser (the “Access Agreement”), Purchaser has been given the opportunity to make a physical
inspection of the Property, including an inspection of the environmental condition thereof, and to examine the Deliveries and other documents and files concerning the leasing, maintenance, operation and financial performance of the Property,
including without limitation, copies of Seller’s environmental reports with respect to the Property, but excluding Seller’s partnership and company records, Seller’s existing management agreement, internal memoranda, financial
projections, appraisals, budgets, appraisals, accounting and income tax records and similar proprietary, confidential or privileged information (collectively, the “Confidential Documents”) and to conduct such non-invasive physical
engineering and other studies and tests on or of the Property as Purchaser deemed appropriate in its sole discretion. 

Section 4.3.      Environmental
Reports.        PURCHASER HEREBY ACKNOWLEDGES THAT SELLER HAS DELIVERED TO PURCHASER, AS PART OF THE DELIVERIES COPIES OF THE ENVIRONMENTAL REPORTS LISTED ON EXHIBIT E ATTACHED HERETO. ANY

PURCHASE OF THE PROPERTY, EXCEPT FOR ANY REPORT THAT IS EXPRESSLY CERTIFIED TO PURCHASER BY THE CONSULTANT THROUGH AN EXECUTED RELIANCE LETTER. PURCHASER AGREES THAT SELLER SHALL HAVE NO LIABILITY OR OBLIGATION WHATSOEVER FOR ANY INACCURACY IN OR
OMISSION FROM ANY ENVIRONMENTAL REPORT. PURCHASER HAS CONDUCTED, OR WILL CONDUCT PRIOR TO CLOSING, ITS OWN INVESTIGATION OF THE ENVIRONMENTAL CONDITION OF THE PROPERTY TO THE EXTENT PURCHASER DEEMS SUCH AN INVESTIGATION TO BE NECESSARY OR
APPROPRIATE.

shall be a condition to Purchaser’s obligation to close the transaction contemplated hereunder. Notwithstanding the foregoing sentence, the parties agree that the bracketed provisions in the attached Tenant Estoppels labeled “THIS
BRACKETED LANGUAGE IS NOT A CONDITION OF CLOSING” will be included in the Tenant Estoppels delivered to the Tenants (and Seller agrees that it will remove such brackets and labeling from the forms before presenting them to the Tenants), but the
parties agree that those provisions are not required for the Tenant Estoppels to satisfy the condition in the foregoing sentence and that such provisions may be modified or deleted in their entirety by the Tenants and such modification or deletion
shall not result in the failure of the affected Tenant Estoppel to satisfy such condition.

EFA Guarantor (at no cost to Seller other than amounts for incidental expenses) deliver to Purchaser the following estoppel certificates (each a “Guarantor Estoppel” and collectively, the “Guarantor Estoppels”):

(21) days prior to Closing. Seller shall deliver to Purchaser copies of all executed Guarantor Estoppels received. Seller will use commercially reasonable, diligent, good faith efforts (at no cost to Seller other than amounts for incidental
expenses) to obtain the Guarantor Estoppels, but Purchaser acknowledges and agrees that the delivery of the Guarantor Estoppels shall not be a condition to Purchaser’s obligation to close the transaction contemplated hereunder. 

Section 4.6.    SNDAs. Seller shall request that Tenants (at no cost to Seller other than amounts for
incidental expenses) deliver to Purchaser the following Subordination, Non-Disturbance and Attornment Agreements (each an “SNDA” and collectively, the “SNDAs”): (i) a fully completed Subordination,

obligation to close the transaction contemplated hereunder (the “SNDA Delivery Condition”), provided the Closing occurs on or before April 27, 2011. If the SNDA Delivery Condition is not satisfied for any reason by the earlier
of the Closing Date as established by Section 5.1 or April 27, 2011, Purchaser may, in its sole discretion: (i) terminate this Agreement by delivering written notice to Seller on or before April 27, 2011, in which event the
Deposit shall be returned to Purchaser; or (ii) elect to close, notwithstanding the non-satisfaction of such condition, and therefore waive satisfaction of such condition. Notwithstanding the foregoing, the parties agree that the bracketed
provisions in the attached SNDA labeled “THIS BRACKETED LANGUAGE IS NOT A CONDITION OF CLOSING” will be included in the SNDAs delivered to the Tenants (and Seller agrees that it will remove such brackets and labeling from the forms before
presenting them to the Tenants), but the parties agree that those provisions are not required for the SNDAs to satisfy the SNDA Delivery Condition and that such provisions may be modified or deleted in their entirety by the Tenants and such
modification or deletion shall not result in the failure of the affected SNDA to satisfy the SNDA Delivery Condition.

Purchaser acknowledge that the Property is subject to those certain Declarations between Seller and M.M. Warburg & Co KGaA recorded under Clerk’s File Nos. 20071217001669040 and 20071217001669050, Deed Records of Collin County, Texas

 Section 4.10.      Cooperation with Purchaser’s
Auditors.  Seller shall provide to Purchaser (at Purchaser’s expense and at no cost to Seller) copies of, or shall provide Purchaser access to, such factual information (excluding any Confidential Documents) as may be reasonably
requested by Purchaser, and in the possession or control of Seller, or its property manager or accountants, to enable Purchaser (or Wells Core Office Income Operating Partnership, L.P. or Wells Core Office Income REIT, Inc.) to file its Form 8-K,
if, as and when such filing may be required by the Securities and Exchange Commission (“SEC”). At Purchaser’s sole cost and expense, Seller shall allow Purchaser’s auditor (Frazier & Deeter or any successor
auditor selected by Purchaser) to conduct an audit of the income statements of the Property for the last complete fiscal year immediately preceding the year that includes the Closing Date (the “Relevant Period”), and shall cooperate
(at no cost to Seller) with Purchaser’s auditor in the conduct of such audit; provided, however, such audit shall only concern the Property and shall expressly exclude any income statements relating to fund-level activity of Seller or any other
investments of Seller. Purchaser shall provide to Seller copies of any GAAP financial statements for the Property covering any portion of Seller’s period of ownership that are generated by Purchaser (provided Purchaser will have no obligation
to generate such financial statements), such financial statements to be provided to Seller after submitting the same to the SEC or other governmental authority or any other third party. Without limiting the foregoing, (i) Purchaser or its
designated independent or other auditor may audit Seller’s operating statements of the Property (if any) for the Relevant Period, at Purchaser’s expense, and Seller shall provide such documentation as Purchaser or its auditor may
reasonably request in order to complete such audit, and (ii) Seller shall furnish to Purchaser such financial and other information as may be reasonably required by Purchaser to make any required filings with the SEC or other governmental
authority; provided, however, that the foregoing obligations of Seller shall be limited to providing such information or documentation as may be in the possession of, or reasonably obtainable by, Seller, its property manager or accountants, at no
out-of-pocket cost to Seller, and in the format that Seller (or its property manager or accountants) have maintained such information. At no out-of-pocket cost to Seller, and at the specific request of Purchaser, Seller shall cooperate reasonably
with Purchaser to arrange for interviews of the Tenants and governmental authorities in connection with the Property, and Seller shall have the right to have a representative present at any such meeting. Nothing contained in this
Section 4.10 shall expand any representations or warranties of Seller set forth in this Agreement, and Seller does not make, and expressly disclaims, any representations and warranties to Purchaser with respect to the information to be
provided as described in this Section 4.10, and no such information shall be relied upon by Purchaser. The provisions of this Section 4.10 shall expressly survive Closing until the date which is five (5) years after the
Closing Date. 
 Section 4.11.        Operating
Agreements.  Seller, without cost to Purchaser, shall deliver written notice of termination at Closing for all Operating Agreements except for the Hudson Agreement. Purchaser will assume the obligations arising from and after the
Closing Date under the Operating Agreements. The assumption by Purchaser of the obligations of Seller under such Operating Agreements shall include only such obligations that arise or accrue from and after the date of Closing.

set forth in this Agreement are theretofore fully satisfied or performed, it being fully understood and agreed, however, that Purchaser may waive (either expressly or implicitly pursuant to Section 3.1(b) with respect to matters that
could form the basis of a Subsequent Exception that are not timely objected to by Purchaser), at or prior to Closing, any conditions that are unsatisfied or unperformed at such time, the consummation of the transaction contemplated hereby (the
“Closing”) shall be held at the offices of Escrow Agent at 200 Galleria Parkway, Suite 2060, Atlanta, Georgia 30339, at 9:00 a.m., Eastern daylight savings time on the earlier of (i) May 17, 2011, (ii) the date that

Escrow Agent has authority to transfer the full amount of the Purchase Price, adjusted by prorations, payment of closing costs and other adjustments set forth herein or on the Closing Statement, to Seller upon receipt of Seller’s instructions

legal description set forth in the Special Warranty Deed shall be identical to the Land as described in Exhibits A-1 and A-2 attached hereto. In the event the New Survey shall differ from the legal description set forth on

person or persons executing documents on behalf of Seller; 
 (i)        the Tenant

or Purchaser to consummate the transaction contemplated by this Agreement and which are usual and customary in similar commercial real estate closings in the Frisco, Texas metropolitan area. 

Section 5.3.     Purchaser’s Obligations at Closing.    At Closing,
Purchaser shall: (i) pay to Seller the full amount of the Purchase Price (less the amount of the Deposit released by the Escrow Agent and to be applied towards the Purchase Price and less the amount of the Repairs Credit), as increased or
decreased by prorations and adjustments as herein provided, in immediately available wire transferred funds pursuant to Section 2.4 hereof and (ii) obtain or execute, at Purchaser’s expense, and deliver in escrow to Escrow
Agent all of the following documents (all of which shall be duly executed, acknowledged, and notarized where required and shall survive the Closing):

 (g)      a certificate of Purchaser, dated as of the Closing

Date; 
 (h)      any returns, questionnaires and other documents as shall be required pursuant
to Section 5.5(a) hereof; and 
 (i)       such additional documents as shall be
reasonably required by the Title Company or Seller to consummate the transaction contemplated by this Agreement and which are usual and customary in similar commercial real estate closings in the Frisco, Texas metropolitan area. 

Section 5.4.        Credits and Prorations. 

(a)      All income and expenses of the Property shall be apportioned as of 11:59 p.m. on the day
prior to the Closing Date, as if Purchaser were vested with title to the Property during the entire day on which the Closing occurs. Such prorated items shall include, without limitation, the following: 

(i)       all Rents, including all Billbacks other than those for tenant work order
income (which shall instead be fully for the account of the party paying or incurring the same), if any, as and when collected; 
 (ii)      taxes and assessments levied against the Property (including personal property taxes on the Personal Property) in accordance with Section 5.4(b)(ii) below;

 (iii)     utility charges for which Seller is liable, if any, in accordance with
Section 5.4(b)(iv) below; 
 (iv)     all amounts payable under the Operating
Agreements which are assigned to Purchaser pursuant to Section 5.2(b); and 

(v)      any other operating expenses or other items due and payable pertaining to the
Property which are customarily prorated between a purchaser and a seller in the county in which the Property is located. 

(b)      Notwithstanding anything contained in Section 5.4(a) hereof: 

(i)       At Closing, (A) Purchaser shall receive a credit against the Purchase
Price in the amount of all cash Security Deposits (to the extent such Security Deposits have not been applied against delinquent Rents or otherwise as provided in the Leases) and interest accrued thereon, to the extent that either the Leases or
applicable law requires that the same bear interest, together with a detailed inventory of such Security Deposits certified by Seller at Closing, and (B) Seller shall be entitled to receive and retain such refundable cash and deposits.

  
 22 

 (ii)      Any real estate taxes and
assessments applicable to the year of Closing paid at or prior to Closing shall be prorated based upon the amounts actually paid. If such taxes and assessments due and payable for the year of Closing for the Property have not been paid before
Closing, Seller shall be charged at Closing an amount equal to that portion of such taxes and assessments which relates to the period before Closing and Purchaser shall assume and pay the taxes and assessments for the year of Closing prior to their
becoming delinquent. Any such apportionment made with respect to a tax year for which the tax rate or assessed valuation, or both, have not yet been fixed shall be based on the prior year’s tax bill. To the extent that the actual taxes and
assessments for the current year for the Property differ from the amount apportioned at Closing, the parties shall make all necessary adjustments by appropriate payments between themselves within thirty (30) days after Purchaser presents to
Seller a copy of the final tax bill, Purchaser’s calculation of the reproration of the taxes and assessments and appropriate back-up materials related to the calculation. In addition, Seller may inspect Purchaser’s books and records
related to the Property to confirm Purchaser’s calculation. If after Closing there is an adjustment or reassessment by any governmental authority with respect to, or affecting, any real estate taxes or assessments for the Property for the year
of Closing or any prior year, any additional tax or assessment payment for the Property required to be paid that is not reimbursable by Tenants under the Leases with respect the year of Closing shall be prorated between Purchaser and Seller and any
such additional tax or assessment payment for the Property for any year prior to the year of Closing shall be paid by Seller to the extent not reimbursable by Tenants under the Leases. This agreement shall expressly survive the Closing. 

(iii)     If the annual reconciliation of tenant pass-throughs under the Leases for the 2011
calendar year (excluding Billbacks, which shall be governed by Section 5.4(a)(i) above) results in there being amounts due and payable by the Tenants, Purchaser will use commercially reasonable efforts to collect such amounts (provided,
however, that commercially reasonable efforts exclude the obligation to declare a Tenant in default under its Lease or to file suit to collect such amounts) and will pay Seller its prorated share of such amounts promptly upon Purchaser’s
receipt (but in no event later than June 30, 2012, provided Purchaser actually receives such amounts from the Tenants). If such reconciliation results in there being refunds due and payable to Tenants on account of the pass-throughs of
specifically documented expenses, Seller will pay to Purchaser its prorated share of such amounts promptly upon receipt of a written request therefor from Purchaser (which shall in no event be delivered later than June 30, 2012). In the event
that there shall be any Rents or other charges under any Leases which, although relating to a period prior to Closing, do not become due and payable until after Closing (excluding Billbacks, which shall be governed by Section 5.4(a)(i)
above), then any Rents or charges of such type received by Purchaser or its agents subsequent to Closing (excluding Billbacks) shall, to the extent applicable to a period extending through the Closing, be prorated between Seller and Purchaser as of
Closing and Seller’s portion thereof shall be paid to Seller by Purchaser promptly upon Purchaser’s receipt of such Rent or other charges (excluding Billbacks). 

(iv)     Except for utilities which are the direct responsibility of the Tenants to the
applicable public or private utilities supplier, Seller shall pay all utility bills received 

  
 23 

 
prior to Closing and shall be responsible for utilities furnished to the Property prior to Closing. Purchaser shall be responsible for the payment of all bills for utilities furnished to the
Property subsequent to the Closing. Seller and Purchaser hereby agree to pay their respective shares of all utility bills (except for utilities which are the direct responsibility of the Tenants) received subsequent to Closing (if they include a
service period prior to the date of Closing), which agreement shall survive Closing. Seller shall be entitled to all deposits presently in effect with the utility providers. 

(v)      If Rents payable by the Tenants, or Billbacks incurred by Seller, for the month in
which the Closing occurs or any prior period have not been received by Seller as of Closing, Purchaser will invoice for and use commercially reasonable efforts to collect such amounts from the Tenants (provided, however, that commercially reasonable
efforts exclude the obligation to declare a Tenant in default under its Lease or to file suit to collect such amounts) and will pay Seller its prorated share of such amounts promptly upon Purchaser’s receipt in accordance with
Section 5.4(b)(vi). 
 (vi)     Seller and Purchaser agree that all Rents
received by Purchaser after Closing will be applied first (1st) to the Billbacks that are paid or incurred by Seller prior to the Closing Date, second (2nd) to Rents that are due and payable for the month in which the Closing occurs (excluding Billbacks), third
(3rd) to Rents that become due and payable after the
month in which Closing occurs (including Billbacks that are paid or incurred by Purchaser on or after the Closing Date), in reverse order of maturity, and fourth (4th) to Rents (excluding Billbacks) that are due and payable for all periods prior to the month in which Closing
occurs, in reverse order of maturity. 
 (vii)    Seller may attempt to collect any
delinquent Rents or Billbacks owed Seller and may institute any lawsuit or collection procedures, but may not evict or seek to evict any Tenant or terminate or seek to terminate any Lease. Purchaser shall promptly provide Seller any information in
Purchaser’s possession that is reasonably necessary for Seller to invoice Tenants for Billbacks for electricity and after-hours HVAC. 
 (viii)   For the period commencing on March 1, 2011 (being the day immediately after the last day covered by the aged delinquency reports set forth on Exhibit R) and ending on
the Closing Date, except for electricity and after-hours HVAC charges, Seller will not without Purchaser’s consent, which may not be unreasonably withheld, conditioned or delayed pay or incur costs that would constitute a Billback if the amount
of any single Billback would exceed $10,000.00 or if the aggregate amount of all such Billbacks would exceed $25,000.00. At Closing, the Closing Statement shall identify those Billbacks (i) for electricity and after-hours HVAC charges then
invoiced and due and payable by Tenants, and (ii) for tenant work orders then known to Seller to have been paid or incurred but not yet invoiced to Tenants (it being understood that there will be additional Billbacks for electricity and
after-hours HVAC charges, and that there may be additional Billbacks for tenant work orders, each of which will not be known to Seller on the Closing Date but that nonetheless shall be adjusted for as they become known pursuant to
Section 5.4(a)(i) and Section 5.4(b)(vi)). “Billbacks” means, with respect to each Lease, a reimbursement from the Tenant to Seller paid for electricity charges, after-hours HVAC charges and other work order
income which are paid or incurred by the 

  
 24 

 
landlord under the Lease and to which the landlord is entitled to reimbursement from the Tenant; provided, however, that Billbacks do not include expenses included in “Annual Rental
Adjustment” (as defined in the Leases). Billbacks are invoiced to Tenant by Seller on a trailing basis; e.g., amounts paid or incurred by the landlord relating to the month of January are billed to Tenant in mid- or late-February and are due
and payable from Tenant immediately 
 (c)      Except as otherwise provided herein, any revenue
or any expense amount that is the obligation of Seller and is not paid by the Tenants under the Leases and that which cannot be ascertained with certainty as of Closing shall be prorated on the basis of the parties’ good faith reasonable
estimate of such amount, and shall be the subject of a final proration ninety (90) days after Closing, or as soon thereafter as the precise amounts can be ascertained. Purchaser shall promptly notify Seller when it becomes aware that any such
estimated amount has been ascertained. Once all revenue and expense amounts have been ascertained, Purchaser shall prepare, and certify as correct, a final proration statement which shall be subject to Seller’s approval, not to be unreasonably
withheld conditioned or delayed. Upon Seller’s acceptance and approval of any final proration statement submitted by Purchaser, such statement shall be conclusively deemed to be accurate and final. 

(d)      Seller may prosecute appeals (if any) of the real estate taxes and assessments for the period
prior to the Closing, and may take related action which Seller deems appropriate in connection therewith. Purchaser shall reasonably cooperate with Seller (but Purchaser shall not be obligated to incur any liability or expense in connection
therewith other than de minimis expenses) in connection with such appeal and collection of a refund of real estate taxes and assessments paid. Seller owns and holds all right, title and interest in and to such appeals and refund, and all amounts
payable in connection therewith shall be paid directly to Seller by the applicable authorities. If such refund or any part thereof is received by Purchaser, Purchaser shall promptly pay such amount to Seller. Any refund received by Seller shall be
distributed as follows: first, to reimburse Seller for all costs incurred in connection with the appeal; second, with respect to refunds payable to Tenants under the Leases, to such Tenants in accordance with the terms of such Leases; and third, to
Seller to the extent such appeal covers the period prior to the Closing, and to Purchaser to the extent such appeal covers the period as of the Closing and thereafter. If and to the extent any such appeal covers the period after the Closing,
Purchaser shall have the right to participate in such appeal. 
 (e)      Upon Closing, Purchaser
shall assume and agree to perform all of Seller’s obligations under or with respect to the Commission Agreement first arising from and after Closing, including without limitation, any and all obligations to pay leasing commissions which are due
or payable under the Leases that result from the exercise of a renewal, extension or expansion of the Leases after Closing. 

(f)       Subject to the final sentence of Section 5.4(c) hereof, the provisions of this
Section 5.4 shall survive Closing. 

  
 25 

 Section 5.5.        Transaction Taxes and
Closing Costs. 
 (a)      Seller and Purchaser shall execute such returns, questionnaires

sale of the Property pursuant hereto. 
 (c)      Purchaser shall pay the fees of any counsel

policy, endorsements or additional title insurance coverage for the Property (including, without limitation, deletion of survey coverage); 
 (ii)      all due diligence costs incurred by Purchaser, including, without limitation, costs incurred to obtain any new environmental reports and property condition
assessment reports or to further update any such reports included among the Deliveries; 

(iii)     costs of any consultants, advisors, brokers (excluding Broker) and other agents or
independent contractors engaged by Purchaser;

 REPRESENTATIONS, WARRANTIES AND COVENANTS 

Section 6.1.          Representations and Warranties of Seller. Seller
hereby makes the following representations and warranties to Purchaser as of the Effective Date, which representations and warranties shall be deemed to have been made again, subject to any changes

  
 28 

 
reported pursuant to Section 5.2(g) as of the Closing; provided, however, all representations and warranties set forth in this Section 6.1 shall be qualified by, and
Seller shall have no liability for any breach if such results from or is based on a condition, state of facts or other matter which was disclosed in the Deliveries or which is reasonably inferable from the Deliveries:

Persons that have been designated by executive order or by the sanction regulations of OFAC as Persons with whom U.S. Persons may not transact business or must limit their interactions to types approved by OFAC (“Specially Designated
Nationals and Blocked Persons”) or otherwise. 
 (ii)      Seller is not

 31

is no default, or claim of default, or any event which the passage of time or notice, or both, would constitute a default on the part of any party to any of such Operating Agreements. All such Operating Agreements are terminable without penalty or
obligation to pay any severance or similar compensation on no more than thirty (30) days notice, except as expressly set forth on Exhibit B. All Operating Agreements are assignable by Seller to Purchaser and no Operating Agreement
prohibits such assignment or provides for any right, claim, or cause of action against Purchaser or the Property upon such assignment. 
 Section 6.2.        Knowledge Defined.    References to the “knowledge” of Seller shall refer only to the current
actual knowledge of the Designated Representatives (as hereinafter defined) of Seller, and shall not be construed, by imputation or otherwise, to refer to the knowledge of Seller or any affiliate of Seller, to any leasing agent, or to any other
officer, agent, manager, representative or employee of Seller or any affiliate thereof or to impose upon such Designated Representatives any duty to investigate the matter to which such actual knowledge, or the absence thereof, pertains. As used
herein, the term “Designated Representatives” shall refer to Birgit Prasch and M. Gregory Moore, each of whom has been actively involved in the management of Seller’s business with respect to the Property. Purchaser hereby
acknowledges and agrees that no Designated Representative shall have any personal liability or responsibility whatsoever with respect to Seller’s representations and warranties hereunder by reason of his or her designation as a Designated
Representative, and no alleged breach of any representation or warranty or any claim whatsoever shall at any time be asserted or enforceable against any one or more of the Designated Representatives. 

Section 6.3.        Survival of Seller’s Representations and
Warranties.      The representations and warranties of Seller set forth in this Agreement, including, without limitation, Section 6.1 hereof, as updated as of the Closing Date in accordance with the
terms of this Agreement, shall survive Closing until 11:59 p.m. on December 31, 2011 (the “Limitations Period”), at which time they will be of no further force or effect except as hereinafter provided in this
Section 6.3. Seller shall have no liability to Purchaser for a breach of any representation or warranty (a) unless and until the valid claims for all breaches aggregate more than ONE HUNDRED THOUSAND AND NO/100 DOLLARS
($100,000.00), in which case Seller shall be liable for the full amount of any such valid claims from the first dollar up to the Cap (as defined in this Section 6.3), and (b) unless written notice containing a description of the
specific nature of such breach shall have been given by Purchaser to Seller prior to 11:59 p.m. on December 31, 2011 and an action shall have been commenced by Purchaser against Seller within thirty (30) days after the expiration of the
Limitations Period. As used herein, the term “Cap” 

  
 32 

 
shall mean an amount equal to ONE MILLION AND NO/100 DOLLARS ($1,000,000.00). In no event whatsoever shall Seller have any liability to Purchaser in excess of the Cap for any claims asserted
after Closing for any breach. 
 Section 6.4.        Covenants of
Seller.  Seller hereby covenants with Purchaser as follows: 
 (a)      From the
Effective Date hereof until the Closing or earlier termination of this Agreement, Seller shall operate and maintain the Property in substantially the same manner in which the Property is being currently operated and maintained. 

(b)      Prior to Closing, Seller shall file a Form 8288-B, FIRPTA Withholding Certificate (the
“FIRPTA Certificate”) in the form required by the Internal Revenue Service, a copy of which shall be provided to Purchaser on or prior to the Closing, along with proof of delivery to the Internal Revenue Service. The FIRPTA
Certificate will indicate the taxable gain, if any, that Seller will recognize upon the sale of the Property to Purchaser and the tax liability amount required to be paid to the Internal Revenue Service in connection therewith (the
“Certificate Tax Amount”). Pursuant to Section 4.01 of Revenue Procedure 2000-35, 2000-2 CB 211 (August 9, 2000) and the filing of such FIRPTA Certificate with the Internal Revenue Service prior to the date of sale, Purchaser
is required to withhold from the sales proceeds ten percent (10%) of the gross sales proceeds derived from the sale of the Property, but is not required to pay such withheld amounts to the Internal Revenue Service pending approval of said
FIRPTA Certificate by the Internal Revenue Service. Accordingly, Seller and Purchaser agree that Purchaser shall withhold ten percent (10%) of the gross sales proceeds (the “Escrowed Funds”), from the Purchase Price and pay the
Escrowed Funds to Escrow Agent, acting as withholding escrow agent (“Withholding Escrow Agent”), to hold pending consideration of the FIRPTA Certificate by the Internal Revenue Service. If the Internal Revenue Service approves the
FIRPTA Certificate, Seller and Purchaser shall direct Withholding Escrow Agent to apply the Escrowed Funds to pay such approved tax liability (the “Final Tax Liability”) within twenty (20) days after such approval. If the Final
Tax Liability is greater than the Escrowed Funds, then Seller shall be fully liable to the Internal Revenue Service for all amounts owed over and beyond the Escrowed Funds. If the Final Tax Liability is less than the Escrowed Funds, then Withholding
Escrow Agent shall promptly pay the excess to Seller, together with the interest or income earned on the Escrowed Funds. If the IRS denies the FIRPTA Certificate, then the Seller and Purchaser shall direct Withholding Escrow Agent to immediately pay
the Escrowed Funds to the Internal Revenue Service in fulfillment of the Purchaser’s obligations under FIRPTA. It is anticipated by Seller that the Final Tax Liability will equal the Certificate Tax Amount. Seller shall promptly forward to
Purchaser any written communications from or to the Internal Revenue Service regarding the FIRPTA Certificate. Seller and Purchaser acknowledge that the IRS normally acts on applications received within 90 days of the receipt of all information
necessary to make a proper determination as to required FIRPTA withholding. Seller shall file or cause to be filed any and all tax returns, information returns or any other required filings in connection with the transfer on or before the due date
of such returns with the Internal Revenue Service and timely pay any and all tax liabilities associated therewith. Seller hereby agrees to hold Purchaser harmless from and against any and all losses, liabilities, claims, damages, costs and expenses
(including reasonable attorneys’ fees, interest and penalties) incurred or realized by Purchaser and relating to the payment to the Internal Revenue Service of any such withholding tax due

  
 33 

 
upon the sale of the Property by Seller to Purchaser. Each of Seller and Purchaser agrees to execute and deliver at the Closing an escrow agreement with Withholding Escrow Agent that reflects the
provisions of this Section 6.4(b) in the form attached hereto as Exhibit S (the “Withholding Escrow Agreement”). Such escrow agreement shall provide for the investment of the Escrowed Funds in designated
investments or accounts available to Escrow Agent and approved by Seller, and all interest or other income earned thereon shall be added to and deemed a part of the Escrowed Funds. Seller will pay all costs and expenses relating to the escrow
account established pursuant to this Section 6.4(b). In the event that a FIRPTA Certificate is not filed in accordance with this Section 6.4(b) prior to Closing, Purchaser shall withhold ten percent (10%) of the gross
sales proceeds from the Purchase Price and remit such amount to the Internal Revenue Service in accordance with its obligations set forth in Section 1445 of the Internal Revenue Code. 

(c)      From the Effective Date through the Closing, Seller shall not modify, amend or terminate the
Leases without first obtaining Purchaser’s prior written consent, which consent may be granted or withheld in Purchaser’s sole discretion. 
 (d)      From the Effective Date through the Closing, Seller shall not enter into any lease or similar agreement with respect to the occupancy of the Property or any portion
or portions thereof without first obtaining Purchaser’s prior written consent, which consent may be granted or withheld in Purchaser’s sole discretion. 
 (e)      Seller hereby covenants that, from the Effective Date of this Agreement up to and including the Closing Date, Seller shall not, without Purchaser’s prior
written consent, which may be granted or withheld in Purchaser’s sole discretion: (i) negotiate with any third party respecting the sale of the Property or any interest therein, (ii) enter into any new agreement of any kind respecting
the Property; (iii) waive in writing any rights of Seller under the Leases; (iv) grant or otherwise create or consent to the creation of any easement, restriction, lien, assessment, or encumbrance respecting the Property; or
(v) create or modify any exceptions to title to the Property, or initiate or consent to any action with respect to zoning or other Property entitlements or permits. 
 (f)       Seller shall neither transfer nor remove any Personal Property or fixtures from the Property after the Effective Date except for the purposes of replacement
thereof, in which case such replacements shall be promptly installed and shall be comparable in quality to the items being replaced. 
 (g)      Seller shall, from and after the Effective Date through the Closing Date, use commercially reasonable efforts to perform and discharge all of the duties and
obligations and comply with every covenant and agreement of the landlord under the Leases, at Seller’s expense, in the manner and within the time limits required thereunder. Furthermore, Seller shall, for the same period of time, use
commercially reasonable efforts to cause the Tenants to perform all of their duties and obligations under the Leases and otherwise comply with each and every one of their covenants and agreements under the Leases. 

  
 34 

 (h)      From the Effective Date through the Closing, Seller
shall continue to carry the same special form/”all risk” insurance covering the Property that is currently in force and effect. 
 Section 6.5.      Representations and Warranties of Purchaser.    Purchaser hereby makes the following representations and warranties to
Seller as of the Effective Date, which representations and warranties shall be deemed to have been made again as of the Closing, subject to Section 5.3(g) hereof: 
 (a)      Organization and Authority.     Purchaser has been duly organized and is validly existing under the laws of the State of Georgia.
Purchaser has the full right and authority to enter into this Agreement and to consummate or cause to be consummated the transaction contemplated by this Agreement. The person or persons signing this Agreement on behalf of Purchaser are authorized
to do so. 
 (b)      Pending Actions.     To Purchaser’s
knowledge, there is no action, suit, arbitration, unsatisfied order or judgment, government investigation or proceeding pending against Purchaser which, if adversely determined, could individually or in the aggregate materially interfere with the
consummation of the transaction contemplated by this Agreement. 
 (c)      Compliance with
International Trade Control Laws and OFAC Regulations. 

(i)       Purchaser is not now nor shall it be at any time until Closing a Person with
whom a U.S. Person is prohibited from transacting business of the type contemplated by this Agreement, whether such prohibition arises under United States law, regulation, executive orders and lists published by OFAC (including those executive
orders and lists published by OFAC with respect to Persons that have been designated as Specially Designated Nationals and Blocked Persons) or otherwise. 
 (ii)      Neither Purchaser nor Wells Core Office Income Operating Partnership, L.P. is now, and neither shall be at any time until Closing, a Person with whom a U.S. Person,
including a Financial Institution, is prohibited from transacting business of the type contemplated by this Agreement, whether such prohibition arises under United States law, regulation, executive orders and lists published by the OFAC (including
those executive orders and lists published by OFAC with respect to Specially Designated Nationals and Blocked Persons) or otherwise. 
 (iii)     Purchaser hereby covenants and agrees that if Purchaser obtains knowledge that any of the representations and warranties contained in this Section 6.5(c) is
or becomes false, then Purchaser will immediately notify Seller in writing, and in such event, Seller will have the right to terminate this Agreement without penalty or liability to Seller immediately upon delivery of written notice thereof to
Purchaser, in which event the Deposit will promptly be returned to Purchaser and neither party will have any further rights or obligations under this Agreement, except for such as specifically survive termination. 

  
 35 

 Section 6.6.        Survival of
Purchaser’s Representations and Warranties.    The representations and warranties of Purchaser set forth in Section 6.5 hereof shall survive Closing until the expiration of the Limitations Period. 

Section 6.7.        Knowledge of Purchaser
Defined.      References to the “knowledge” of Purchaser shall refer only to the current actual knowledge of the Purchaser Designated Representatives (as hereinafter defined), and shall not be
construed, by imputation or otherwise, to refer to the knowledge of Purchaser or any affiliate of Purchaser, to any leasing agent, or to any other officer, agent, manager, representative or employee of Purchaser or any affiliate thereof or to impose
upon such Purchaser Designated Representatives any duty to investigate the matter to which such actual knowledge, or the absence thereof, pertains. As used herein, the term “Purchaser Designated Representatives” shall refer to Keith
Willby. Seller hereby acknowledges and agrees that no Purchaser Designated Representative shall have any personal liability or responsibility whatsoever with respect to Purchaser’s representations and warranties hereunder by reason of his or
her designation as a Purchaser Designated Representative and no alleged breach of any representation or warranty or any claim whatsoever shall at any time be asserted or enforceable against any one or more of the Purchaser Designated
Representatives. 
 ARTICLE VII 
 DEFAULT 
 Section 7.1.    Default by
Purchaser.  In the event that the sale of the Property as contemplated hereunder is not consummated due to Purchaser’s default hereunder, Seller shall be entitled, as its sole and exclusive remedy, to terminate this Agreement by
written notice to Purchaser and Escrow Agent and to immediately receive the Deposit as liquidated damages (and not as a penalty) for the breach of this Agreement, it being agreed between the parties hereto that: (i) it would be impracticable
and extremely difficult to fix or establish actual damages of Seller in the event of a default hereunder by Purchaser and (ii) the amount of the Deposit is the parties’ best and most reasonable and fair estimate of Seller’s damages in
the event of Purchaser’s default. Seller agrees that in the event of a default by Purchaser, Seller shall not initiate any proceeding to recover damages from Purchaser, but shall limit its recovery to the receipt and retention of the Deposit,
Seller hereby expressly WAIVING AND RELINQUISHING any and all other remedies at law or in equity and Seller hereby WAIVES AND RELEASES any right to (and hereby covenants that it shall not) sue Purchaser: (a) for specific performance of this
Agreement, or (b) to recover any damages of any nature or description other than or in excess of the Deposit. Purchaser hereby WAIVES AND RELEASES any right to (and hereby covenants that it shall not) sue Seller or seek or claim a refund of the
Deposit (or any part thereof) on the grounds it is unreasonable in amount and exceeds Seller’s actual damages or that its retention by Seller constitutes a penalty and not agreed upon and reasonable liquidated damages. 

Section 7.2.    Default by Seller.  If Seller defaults in any of its obligations under this
Agreement to be performed at or prior to Closing, Purchaser shall be entitled, as its sole remedy, either (a) to receive the return of the Deposit from Escrow Agent, and in the case of a 

  
 36 

 
material default by Seller, Seller shall also pay to Purchaser all actual out-of-pocket expenses incurred by Purchaser in connection with this transaction, provided that such reimbursement of
out-of-pocket expenses shall not exceed the sum of $100,000 in the aggregate, which return and reimbursement, if applicable, shall operate to terminate this Agreement and release Seller from any and all liability hereunder, or (b) to enforce
specific performance of Seller’s obligation to convey the Property to Purchaser in accordance with this Agreement. Except as set forth above, Purchaser expressly WAIVES AND RELEASES its rights to seek damages in the event of Seller’s
default hereunder. In no event shall Seller be liable for consequential, speculative, remote or punitive damages and Purchaser hereby WAIVES AND RELEASES any right to seek or collect any such consequential, speculative, remote or punitive damages.
Purchaser shall be deemed to have elected to terminate this Agreement and to receive a return of the Deposit from Escrow Agent and, if applicable, the reimbursement of Purchaser’s actual, out-of-pocket expenses pursuant to clause
(a) above, if Purchaser fails to file suit for specific performance against Seller in a court having jurisdiction in the county and state in which the Property is located, on or before sixty (60) days following the date upon which the
Closing was to have occurred. 
 Section 7.3.     Recoverable
Damages.        Notwithstanding Section 7.1 and Section 7.2 hereof, in no event shall the provisions of Section 7.1 and Section 7.2 limit the damages
recoverable by either party against the other party due to the other party’s obligation to indemnify such party in accordance with Section 4.2(c), Section 6.4(b) and Section 9.1 of this Agreement. 

ARTICLE VIII 

RISK OF LOSS 
 Section 8.1.    Damage or Destruction.    If any of the Improvements shall be destroyed or damaged prior to the Closing, and if either the estimated
cost of repair or replacement exceeds Two Million and No/100th Dollars ($2,000,000.00) or the damage is such that either the T-Mobile Building I Lease or the T-Mobile Building II Lease is terminated or terminable at the option of T-Mobile (unless
the termination option is waived in writing), Purchaser may, by written notice given to Seller within twenty (20) days after receipt of written notice from Seller of such damage or destruction, elect to terminate this Agreement, in which event
the Deposit shall immediately be returned by Escrow Agent to Purchaser and the rights, duties, obligations, and liabilities of all parties hereunder shall immediately terminate and be of no further force or effect, except for the obligations of the
parties hereunder which expressly survive the termination of this Agreement. If Purchaser does not elect to terminate this Agreement pursuant to this Section 8.1, or has no right to terminate this Agreement (because the damage or
destruction does not exceed $2,000,000.00 and would not give rise to a right by T-Mobile to terminate either the T-Mobile Building I Lease or the T-Mobile Building II Lease), and the sale of the Property is consummated, Purchaser shall be entitled
to receive all insurance proceeds paid or payable to Seller by reason of such destruction or damage under the insurance required to be maintained by Seller pursuant to Section 6.4(h) hereof or insurance maintained by the Tenants under
the Leases (less amounts of insurance theretofore received and applied by Seller to costs actually incurred for restoration). Seller shall not settle or release any damage or 

  
 37 

 
destruction claims without obtaining Purchaser’s prior written consent in each case, such consent not to be unreasonably withheld. All said insurance proceeds received by Seller by the date
of Closing shall be paid by Seller to Purchaser at Closing, together with the amount of the deductible under Seller’s all risk property damage insurance policy. If the amount of said casualty proceeds is not settled by the date of Closing,
Seller shall execute at Closing all proofs of loss, assignments of claim, and other similar instruments reasonably required to enable Purchaser to receive all of Seller’s right, title, and interest in and under said insurance proceeds for the
period of time commencing on the date of Closing, but Seller shall be entitled to sums paid for the period of time prior to the date of Closing. 
 Section 8.2.    Condemnation.    If, prior to the Closing, all or any part of the Property or any means of ingress, egress or access to the Property is
subjected to a bona fide threat of condemnation by a body having the power of eminent domain or is taken by eminent domain or condemnation (or sale in lieu thereof), or if Seller has received notice that any condemnation action or proceeding with
respect to the Property or any means of ingress, egress or access to the Property is contemplated by a body having the power of eminent domain, Seller shall give Purchaser immediate written notice of such threatened or contemplated condemnation or
of such taking or sale, and if Purchaser reasonably determines that such condemnation will materially interfere with the operation or value of such Property, Purchaser may by written notice to Seller given within thirty (30) days of the receipt
of such notice from Seller, elect to cancel this Agreement. If Purchaser chooses to cancel this Agreement in accordance with this Section 8.2, then the Deposit shall be returned immediately to Purchaser by Escrow Agent and the rights,
duties, obligations, and liabilities of the parties hereunder shall immediately terminate and be of no further force and effect, except for the obligations of the parties hereunder which expressly survive the termination of this Agreement. If
Purchaser does not elect to terminate this Agreement in accordance herewith, this Agreement shall remain in full force and effect and the sale of the Property contemplated by this Agreement, less any interest taken by eminent domain or condemnation,
or sale in lieu thereof, shall be effected with no further adjustment and without reduction of the Purchase Price, and at the Closing, Seller shall assign, transfer, and set over to Purchaser all of the right, title, and interest of Seller in and to
any awards that have been or that may thereafter be made for such taking. At such time as all or a part of the Property is subjected to a bona fide threat of condemnation and Purchaser shall not have elected to terminate this Agreement as
hereinabove provided, Purchaser shall be permitted to participate in the proceedings as if Purchaser were a party to the action, as its interests may appear. Seller shall not settle or agree to any award or payment pursuant to condemnation, eminent
domain, or sale in lieu thereof without obtaining Purchaser’s prior written consent thereto in each case, such consent not be unreasonably withheld. 
 ARTICLE IX 
 COMMISSIONS 

Section 9.1.        Brokerage Commissions.  Seller acknowledges that
Broker has been engaged by Seller to assist with this transaction and Seller shall be fully responsible for any compensation owed Broker in connection with this transaction pursuant to a separate written agreement between Seller and Broker. Broker
hereby agrees that it shall accept such 

  
 38 

 
commission in full and complete satisfaction of the commission payable to it in connection with the purchase and sale of the Property and that in the event the purchase and sale of the Property
is not closed and consummated for any reason whatsoever, then no commission shall have been earned and none shall be payable. Broker agrees that it will execute and deliver to Purchaser and Seller at Closing a waiver of all broker’s lien rights
in form and content reasonably acceptable to Purchaser, Seller and the Title Company (the “Broker Lien Waiver”). Seller shall and does hereby indemnify and hold harmless Purchaser from and against any claim, whether or not
meritorious, for any real estate sales commission, finder’s fees, or like compensation in connection with the sale contemplated hereby and arising out of any act or agreement of Seller, including any claims asserted by Broker. Likewise,
Purchaser shall and does hereby indemnify and hold harmless Seller from and against any claim, whether or not meritorious, for any real estate sales commission, finder’s fees, or like compensation in connection with the sale contemplated hereby
and arising out of any act or agreement of Purchaser, except any such claims asserted by Broker. The provisions of this Section 9.1 shall survive Closing or any termination of this Agreement. 

ARTICLE X  

DISCLAIMERS AND WAIVERS
