dated more than 30 days prior to the Closing Date (or, if they are dated more than 30 days prior to the Closing Date, then updated prior to the Closing Date
by an update certificate in the form attached as Exhibit J-2for each such Estoppel Certificate), and (iii) contain information that is consistent with and confirms the terms of the tenant leases, and information contained in the Rent
Roll delivered to Purchaser on or before the date of this Agreement (the Estoppel Condition). Sellers failure to satisfy the Estoppel Condition shall in no instance constitute a default by Seller under this Agreement and in
the event of such failure, Purchasers sole right shall be either to terminate this Agreement in which case the Earnest Money, and all interest earned thereon, shall be returned to Purchaser, or to waive the Estoppel Condition (to the extent
not satisfied) and proceed with the Closing. In addition, Seller agrees that upon the request of Purchaser prior to the Approval Date, Seller shall deliver to the tenants at the Property, the form of subordination non-disturbance and attornment
agreement attached hereto as Exhibit N and made a part hereof and shall request that the tenants execute and return the SNDAs prior to Closing. Purchaser expressly agrees that the failure to obtain SNDAs is not a default or breach by Seller
under this Agreement nor is the receipt of any SNDAs a precondition to Purchasers obligations hereunder.

(b)
maintain the Property in the condition in which it existed as of the Date of Agreement, normal wear and tear excepted, free from mechanics liens, and operate the Property in a manner consistent with current practice, and perform its
obligations under the Leases, Contracts and Licenses;

(c) keep in existence all fire and extended coverage insurance
policies, and all public liability insurance policies, that are in existence as of the Date of Agreement with respect to the Property;

(d) not (i) amend, waive any rights under, terminate or extend any Lease, Contract, or License, (ii) apply any security or other deposits held under any Lease, Contract, or License to delinquent
rents, or (iii) enter into new leases, contracts, licenses and telecommunications agreements, without Purchasers prior written consent, which will not be unreasonably withheld by Purchaser on or prior to the Approval Date, but may be
withheld in Purchasers sole discretion after the Approval Date;

(e) upon at least twenty-four
(24) hours notice to Seller, permit Purchaser, its engineer, architect or other agents, during normal business hours (or such other times as are reasonable), to enter onto the Land for the purpose of making inspections thereof;

(f) promptly advise Purchaser in writing of any changes in circumstances that would render the representations and
warranties made by Seller herein false or misleading in any material respect; and

(g) upon written notice from
Purchaser on or before the Approval Date, give appropriate notices of termination of Contracts designated by Purchaser (but only to the extent termination is permitted thereunder without a penalty); provided, however, that if the notice period
required to terminate such Contracts will not have run prior to Closing, Seller shall assign and Purchaser shall assume any remaining rights and obligations under such Contracts pursuant to the Assignment and Assumption. Notwithstanding the
foregoing, Purchaser shall have no obligation to assume any property management or leasing agreement for any period of time.

| | 10. | APPROVAL DATE.
| | --- | --------------

(a) During
the period (the Inspection Period) from the Date of Agreement through the Approval Date identified in Line 8 of the Summary Statement (the Approval Date), (A) Seller shall permit Purchaser to
examine, at all reasonable times, the books and records (including without limitation historical financial and operating statements) in Sellers possession or control relating to the Property, (B) Purchaser shall have the right, at all
reasonable times, to (I) inspect the Land, Improvements, Appurtenant Rights and Personal Property, (II) review the Leases, the Contracts and the Licenses, (III) interview the tenants and any property manager, and (IV) conduct
geophysical feasibility tests of the Property and environmental audit or audits of the Property (with copies of the reports relating to such audits delivered to Seller when completed), including sampling, and (C) Purchaser shall be given
complete access to the Property for the purpose of making such tests, inspections and investigations. All of the foregoing inspections, reviews, interviews, tests, investigations and studies to be conducted under this Section 10(a) by
Purchaser shall be subject to the following:

(i) Such studies, tests, inspections, interviews, reviews and investigations
shall take place during normal business hours upon at least 24 hours notice to Seller or its designated agents and Sellers consent shall be required prior to the performance of any drilling, boring or other invasive testing or procedures and
Seller shall be entitled to be present during any such investigation or interview;

(ii) In the event the Closing does not
occur, Purchaser shall promptly return to Seller any documents obtained from Seller or Sellers agents;

(iii)
Purchaser shall not suffer or permit any lien, claim or charge of any kind whatsoever to attach to the Property or any part thereof caused by the activities on the Property of Purchaser, its agents, engineers, employees, contractors or surveyors;
and

(iv) Such tests, investigations and studies shall be at Purchasers sole cost and expense and shall not
unreasonably interfere with the operation of the Property. In the event of any damage to the Property caused by Purchaser, its agents, engineers, employees, contractors or surveyors (including without limitation pavement, landscaping and surface
damage), Purchaser shall pay any cost incurred by Seller to restore the Property to the condition existing prior to the performance of such tests, investigations or studies; such obligation shall survive the termination of this Agreement.

##### Table of Contents

Purchaser shall defend, indemnify and hold Seller harmless from any and all liability, cost and expense
(including without limitation reasonable attorneys fees, court costs and costs of appeal) suffered or incurred by Seller for death or injury to persons or property caused by or arising out of Purchasers reviews, interviews,
investigations, tests, studies and inspections of the Property, excluding any such liability, cost or expense resulting from the negligence or willful misconduct of Seller or its agents, employees or contractors; such obligation shall survive the
Closing or the earlier termination of this Agreement. Prior to commencing any such tests, studies and investigations, Purchaser shall furnish to Seller a certificate of insurance evidencing comprehensive general public liability insurance insuring
the person, firm or entity performing such tests, studies and investigations and listing Seller and Purchaser as additional insureds thereunder. If, in the sole discretion and at the sole election of Purchaser, the Property and/or any of said tests,
inspections or investigations are unsatisfactory to Purchaser, in any manner or for any reason in Purchasers sole discretion, including without limitation for reasons relating to restrictions on use of the Property, matters relating to zoning,
government approvals, title, survey, appraised value or other matters impacting the condition or value of the Property, Purchaser may terminate this Agreement as provided below. If Purchaser notifies Seller, in writing, on or before 5:00 p.m.
(Chicago time) on the Approval Date of Purchasers election to terminate this Agreement, Purchaser shall promptly deliver to Seller copies of all documents, studies and reports obtained by Purchaser in connection with its due diligence (which
obligation shall survive the termination of this Agreement), this Agreement shall terminate, the Earnest Money and all interest earned thereon shall be delivered to Purchaser and the parties hereto shall have no further obligations hereunder (except
for obligations that are expressly intended to survive termination of this Agreement). If Purchaser fails to notify Seller, in writing, on or before 5:00 p.m. (Chicago time) on the Approval Date, of Purchasers election to terminate this
Agreement, Purchasers right to terminate this Agreement under this Section 10(a)shall expire.

(b)
The obligation of Purchaser to close the transaction contemplated by this Agreement is further subject to the condition that: (i) all of the representations and warranties of Seller contained in this Agreement are true and correct, in all
material respects, at the Date of Agreement and as of the Closing Date, (ii) Seller has satisfied the Estoppel Condition, (iii) Title Company is committed to issue the Title Policy, and (iv) all of the obligations and duties of Seller
to be performed hereunder and per the Escrow on or before the Closing Date have been substantially completed in a timely manner. Purchaser shall give written notice to Seller of its election to terminate this Agreement or to proceed with the Closing
within five (5) days after Purchasers receipt of any notice disclosing that any Seller representation and warranty is no longer true and correct; provided, however, that Purchasers failure to give such written notice shall in no
instance constitute a default by Purchaser under this Agreement but shall instead only serve to bar Purchaser from raising such matter as a failure of a condition precedent to Purchasers obligation to close the transaction. Purchasers
election to proceed with the Closing shall result in Purchasers waiver of any remedy resulting from the incorrectness in such representation or warranty or from the incorrectness in any other representation or warranty of Seller of which
Purchaser shall have knowledge at or prior to Closing. The foregoing waiver shall survive the Closing.

advisors (Purchasers Representatives) and as required by law. Purchaser shall be liable for any disclosure of the Confidential Information by any of Purchasers Representatives. The provisions of this
Section 10(c) shall survive the termination of this Agreement. Notwithstanding the foregoing or anything stated to the contrary elsewhere in this Agreement, nothing contained in this Agreement shall impair Purchasers (or its
permitted assignees) right to disclose information relating to the Property (i) to any due diligence representatives and/or consultants that are engaged by, work for or are acting on behalf of, any securities dealers and/or broker dealers
evaluating Purchaser or its permitted assignees, (ii) in connection with any filings (including any amendment or supplement to any S-11 filing) with governmental agencies (including the SEC) by any real estate investment trust (the
REIT) holding an interest (direct or indirect) in any permitted assignee of Purchaser, and (iii) to any broker/dealers in the REITs broker/dealer network and any of the REITs investors.

(d) Purchaser has informed Seller that it is required by law to complete with respect to certain matters relating to the Property

on the terms and conditions of Section 11(a)(ix) below the Purchasers 3-14 Audit Documents (as defined below); and (b) provide to Purchaser in written form, as determined by Seller, answers to the questions relating to the Property
which are set forth in Exhibit M; provided, however, that Seller shall have no liability for any inaccuracy in such answers, except to the extent Seller shall be adjudicated to have committed fraud in answering such questions.

| | 12. | FIRE OR CASUALTY.
| | --- | -----------------

In the event of damage to the
Property by fire or other casualty prior to the Closing Date, Seller shall promptly notify Purchaser of such fire or other casualty. If the fire or other casualty causes damage which would cost in excess of $500,000 to repair (as determined by
Seller and Purchaser in good faith), then Purchaser may elect, by written notice to be delivered to Seller on or before the sooner of (i) the twentieth (20th) day after Purchasers receipt of such notice or (ii) the Closing Date,
to terminate this Agreement, and receive a return of the Earnest Money in which case the parties hereto shall have no further obligations hereunder (except for obligations that are expressly intended to survive the termination of this Agreement). If
the damage to the Property by fire or other casualty prior to the Closing Date would cost less than or equal to $500,000 to repair (as determined by Seller and Purchaser in good faith), Purchaser shall not have the right to terminate its obligations
under this Agreement by reason thereof. If Purchaser does not terminate this Agreement, in any case, Seller shall assign and transfer to Purchaser on the Closing Date all of Sellers right, title and interest in and to all insurance proceeds
payable to Seller on account of such fire or casualty, and Purchaser shall receive a credit against the Purchase Price equal to the lesser of the deductible under Sellers property insurance or the estimated cost to repair and restore the
Property (as determined by Seller and Purchaser in good faith).



| | 13. | CONDEMNATION.
| | --- | -------------

If, prior to the Closing Date, all
or any part of the Property is taken by condemnation or a conveyance in lieu thereof, or if Seller receives notice of a condemnation proceeding with respect to the Property, then Seller shall promptly notify Purchaser of such condemnation or
conveyance in lieu thereof. If the taking or threatened taking involves a material portion of the Property (hereinafter defined), Purchaser may elect, by written notice to be delivered to Seller on or before the sooner of (i) the twentieth
(20th) day after Purchasers receipt of such notice, or (ii) the Closing Date, to terminate this Agreement, in which event the Earnest Money shall be returned to Purchaser, and the parties hereto shall have no further obligations
hereunder (except for obligations that are expressly intended to survive the termination of this Agreement). If Purchaser elects to close this transaction notwithstanding such



13

##### Table of Contents

taking or condemnation, Purchaser shall be entitled to any award given to Seller as a result of such condemnation proceedings, with the same being paid or
assigned to Purchaser at Closing. As used herein, a material portion of the Property means any part of the Property reasonably required for the operation of the Property in the manner operated on the date hereof, as reasonably determined
by Seller and Purchaser in good faith. If any taking or threatened taking does not involve a material portion of the Property, Purchaser shall be required to proceed with the Closing, in which event Seller shall assign to Purchaser any award given
to Seller (or the right to receive any such award) as a result of such condemnation proceedings.



| | 14. | ADJUSTMENTS AND PRORATIONS.
| | --- | ---------------------------

Adjustments and
prorations with respect to the Property shall be computed and determined between the parties as of 12:01 a.m. on the Closing Date (as if Purchaser were vested with title to the Property during the entire Closing Date) as follows:

(a) General real estate taxes, special assessments and personal property taxes shall be prorated as of the Closing Date based on
the then current taxes (if known, based on final tax bills for such period  and if not known, based on the most recent ascertainable taxes) and the special assessments due and owing prior to Closing, and Seller or Purchaser shall receive a
credit at Closing, as appropriate. Without affecting the obligations set forth in this Section 14(a), the prorations for real and personal property taxes shall be equitably pro rated on a net basis (i.e., adjusted for all
tenants liabilities, if any, to pay such items directly to the applicable third-party payees). If final taxes or special assessments are not known as of the Closing, the parties agree to reprorate within thirty (30) days after such
amounts become known.

(b) All rents and other sums receivable 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 Date. 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 (if such rents are received by Seller prior to the Closing Date). All payments from tenants, on account of rent or otherwise, received by Seller after the
Closing Date, whether attributable to the period prior to or after the Closing Date, shall be deemed to be held in trust by Seller for Purchaser and shall be promptly delivered to Purchaser by Seller for application as provided in this
Section 14(b). All payments from tenants, on account of rent or otherwise, received after the Closing Date 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 Date but which were not paid when due. Any customary out-of-pocket 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 delinquent rentals for a period of sixty (60) days after Closing. Thereafter, Seller shall have the right to contact tenants to request payment of
delinquent rentals after the Closing Date and institute legal proceedings to collect such delinquent rentals, but shall have no right to evict any tenant. Any such enforcement or collection efforts by Seller shall be at Sellers sole expense.

##### Table of Contents

(c) On the Closing Date, Seller shall deliver to Purchaser in cash, as a credit
against the Purchase Price or as an adjustment to the prorations provided for elsewhere in this Section 14, as appropriate, an amount equal to all cash security deposits made by tenants occupying the Property which were paid to Seller or
its predecessors by such tenants and which shall not have been applied by Seller or otherwise pursuant to the Leases, together with interest owing thereon pursuant to the applicable Lease, if any, and together with a listing of the tenants to which
such deposits and interest are owing.

(d) All amounts payable, owing or incurred in connection with the Property
under the Contracts to be assumed by Purchaser under the Assignment and Assumption shall be prorated as of the Closing Date.

(e) All utility deposits, if any, may be withdrawn by and refunded to Seller, and Purchaser shall make its own replacement deposits for utilities as may be required by the respective utilities involved.

(f) The Earnest Money shall be paid to Seller at Closing and Purchaser shall be entitled to a credit against the Purchase Price in
the amount thereof.

(g) All utility charges that are not separately metered to tenants shall be prorated to the
Closing Date and Seller shall obtain a final billing therefor and pay any amounts owing therein for the period prior to the Closing Date and Purchaser shall pay any amounts owing for the period on and after the Closing Date. To the extent that
utility bills cannot be handled in the foregoing manner, they shall be prorated as of the Closing Date based on the most recent bills available and reprorated when such final bills become known.

(h) Purchaser shall pay its pro rata share (based on the applicable commencement date of the lease and the lease term) of all
leasing commissions and tenant improvement costs payable with respect to Leases entered into after the Date of Agreement. If Seller has paid such amounts prior to the Closing Date, Purchaser shall reimburse Seller for Purchasers pro rata share
of such payments at Closing. If Seller has not paid such amounts prior to the Closing Date, Purchaser shall receive a credit against the Purchase Price at Closing in an amount equal to Sellers pro rata share of such amounts. Seller shall be
responsible for all leasing commissions and tenant improvement costs payable with respect to the initial terms of the Leases entered into prior to the Date of Agreement (including, but not limited to a certain lease with Travis Association for the
Blind). To the extent that Purchaser shall assume liability for any such item at the Closing, then Purchaser shall receive a credit against the Purchase Price in the amount of any such liability so assumed by Purchaser.

(i) Seller and Purchaser agree that as soon as reasonably possible after the close of the calendar year of the Property, the
parties shall undertake a final master

reconciliation of CAM, taxes and other pass-throughs and additional rent with respect to the Leases and the Property. Such reconciliation shall be final. For
purposes hereof, Seller and Purchaser shall each prepare tenant reconciliations for their respective applicable periods of ownership of the Property. Purchaser shall transmit such information to the tenants.

(j) Unless provided otherwise hereinabove, such other items as are customarily prorated in a purchase and sale of the type
contemplated hereunder shall be prorated as of the Closing Date.

(k) Each of the provisions of this
Section 14 shall survive the Closing until the later of (i) one (1) year from the date of Closing or (ii) three (3) months after the issuance of the final tax bill for the year in which the Closing occurs.



| | 15. | CLOSING COSTS.

costs of recording any releases required to clear title to the Property, (b) Sellers attorneys fees, (c) stamp tax, sales tax, documentary transfer tax or other taxes imposed on the transfer of the Property, (d) the costs
of the Title Commitment, the basic premium for the Title Policy and the cost of any endorsements thereto obtained by Seller in order to clear title, (e) the costs of the Survey, and (f) one-half of all escrow closing fees and costs.
Purchaser shall pay: (i) all fees for recording the deed, (ii) the costs of any endorsements to the Title Policy (except as described in clause (d) above), including without limitation any endorsements to alter the survey exception to
read shortages in area, (iii) Purchasers attorneys fees, and (iv) one-half of all escrow closing fees and costs.



| | 16. | POSSESSION.
| | --- | -----------

Possession of the Property shall be
delivered to Purchaser at Closing, free and clear of all liens and claims other than Permitted Exceptions, Purchaser Exceptions and the rights of the tenants identified on the Rent Roll and of the licensees set forth on Exhibits E and I, in
the same condition as it exists on the Date of Agreement, ordinary wear and tear excepted and except as provided in Sections 12 and 13hereof. Purchaser shall have the right to inspect the Property within three (3) days prior
to Closing to verify that the condition of the Property is as required under this Agreement.



| | 17. | DEFAULT.
| | --- | --------

IF SELLER DEFAULTS HEREUNDER PRIOR TO
CLOSING AND FAILS TO CURE SUCH DEFAULT WITHIN FIVE (5) DAYS AFTER WRITTEN NOTICE OF SUCH DEFAULT, OR IF PRIOR TO CLOSING IT IS DETERMINED THAT THE REPRESENTATIONS AND WARRANTIES SET FORTH IN THIS AGREEMENT SHALL NOT BE TRUE AND CORRECT IN ALL
MATERIAL RESPECTS ON THE DATE OF AGREEMENT AND AS OF THE CLOSING DATE, THEN PURCHASERS SOLE REMEDY SHALL BE TO EITHER (A) TERMINATE THIS AGREEMENT AND RECEIVE A RETURN

OBLIGATION TO THE OTHER ARISING BY VIRTUE OF THIS AGREEMENT (EXCEPT FOR OBLIGATIONS THAT ARE EXPRESSLY INTENDED TO SURVIVE THE TERMINATION OF THIS AGREEMENT), OR (B) PURSUE SPECIFIC PERFORMANCE OF THIS AGREEMENT. IN NO EVENT SHALL SELLER BE
LIABLE FOR ANY ACTUAL, SPECIAL, PUNITIVE, SPECULATIVE OR CONSEQUENTIAL DAMAGES IF THE CLOSING DOES NOT OCCUR. IF THE CLOSING OCCURS, IN NO EVENT SHALL SELLER BE LIABLE FOR ANY SPECIAL, PUNITIVE, SPECULATIVE OR CONSEQUENTIAL DAMAGES, NOR SHALL
SELLERS LIABILITY UNDER ANY REPRESENTATION, WARRANTY, CERTIFICATION, COVENANT, AGREEMENT, PRORATION, REPRORATION, OBLIGATION OR INDEMNITY MADE HEREUNDER OR UNDER ANY OF THE CLOSING DOCUMENTS OR OTHERWISE IN CONNECTION WITH THE TRANSACTIONS
CONTEMPLATED HEREIN EXCEED FIVE HUNDRED THOUSAND DOLLARS ($500,000) IN THE AGGREGATE, PROVIDED, HOWEVER, THAT ANY LIABILITY OF SELLER ARISING UNDER SECTION 14 AND SECTION 19 SHALL NOT BE SUBJECT TO SUCH $500,000 LIMIT (THE
SELLERS MAXIMUM LIABILITY). NONE OF SELLERS PARTNERS, MEMBERS, MANAGERS, OFFICERS, AGENTS OR EMPLOYEES SHALL HAVE ANY PERSONAL LIABILITY OF ANY KIND OR NATURE OR BY REASON OF ANY MATTER OR THING WHATSOEVER UNDER, IN
CONNECTION WITH, ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT, THE CLOSING DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREIN, AND PURCHASER WAIVES FOR ITSELF AND FOR ANYONE WHO MAY CLAIM BY, THROUGH OR UNDER PURCHASER ANY AND ALL RIGHTS TO
SUE OR RECOVER ON ACCOUNT OF ANY SUCH ALLEGED PERSONAL LIABILITY. IF THE SALE IS NOT COMPLETED AS HEREIN PROVIDED BY REASON OF ANY DEFAULT OF PURCHASER, AND PURCHASER FAILS TO CURE SUCH DEFAULT WITHIN FIVE (5) DAYS OF WRITTEN NOTICE OF SUCH
DEFAULT, THIS AGREEMENT SHALL TERMINATE AND SELLER SHALL RETAIN THE EARNEST MONEY AND ANY INTEREST THEREON AS LIQUIDATED DAMAGES IN FULL SETTLEMENT OF ALL CLAIMS AGAINST PURCHASER (WITH THE EXCEPTION OF CLAIMS AGAINST PURCHASER RELATED TO
OBLIGATIONS WHICH ARE EXPRESSLY INTENDED TO SURVIVE THE TERMINATION OF THIS AGREEMENT). THE PARTIES AGREE THAT THE AMOUNT OF ACTUAL DAMAGES THAT SELLER WOULD SUFFER AS A RESULT OF PURCHASERS DEFAULT WOULD BE EXTREMELY DIFFICULT TO DETERMINE
AND HAVE AGREED, AFTER SPECIFIC NEGOTIATION, THAT THE AMOUNT OF THE EARNEST MONEY IS A REASONABLE ESTIMATE OF SELLERS DAMAGES AND IS INTENDED TO CONSTITUTE A FIXED AMOUNT OF LIQUIDATED DAMAGES IN LIEU OF OTHER REMEDIES AVAILABLE TO SELLER AND
IS NOT INTENDED TO CONSTITUTE A PENALTY. THE PROVISIONS OF THIS SECTION 17 SHALL SURVIVE THE CLOSING.
