(b) Legible copies of all documents, whether recorded or unrecorded, referred to in the Title
Commitment; and

(c) A current (i.e., no longer than thirty (30) days old) ALTA As-Built Survey of the Property prepared by a
licensed engineer or surveyor (reasonably acceptable to Buyer) and prepared in accordance with the Minimum Standard Detail Requirements for ALTA/ACSM Land Title Surveys, jointly established and adopted by ALTA and NSPS in 2005, including
Items 1-4, 6-11 and 13-16 of Table A thereof, and pursuant to the Accuracy Standards (as adopted by ALTA and ACSM) in effect (the Survey).

(Items (a) through (c) are collectively referred to as the Title Documents.) Seller has, without cost to Buyer and prior to the Effective Date, delivered to Buyer items (a) and (b), and has, prior to the
Effective Date, ordered the Survey. Buyer shall be solely responsible for all cost and expense of the Survey, and shall pay directly for the Survey promptly following receipt of an invoice therefor, but not later than the Close of Escrow.

3.1.2 Buyers Title Notice. By no later than October 1, 2007, Buyer may approve or disapprove (in its sole and absolute
discretion) the Title Documents for the Property by delivering written notice to Seller (Buyers Title Notice) specifying each title defect or matter which needs to be cured by Seller (Title Defect) and
each Title Company requirement (Title Requirement) which must be satisfied by Seller in order for the Approved Title Policy (as defined below) to be issued for the Property at the Close of Escrow. For purposes of this Agreement,
(a) the term Approved Title Policy shall mean an ALTA Owners Policy of Title Insurance, issued by the Title Company as of the date and time of the recording of the Deed (as defined below), in the amount of the Purchase
Price, insuring Buyer as owner of good, marketable and indefeasible fee simple title to the Real Property, containing such title endorsements as may be designated by Buyer in Buyers Title Notice and subject only to the Permitted Exceptions (as
defined below) for the Real Property, and (b) the term Permitted Exceptions shall mean the title exceptions approved by Buyer pursuant to this Agreement, and the following: (i) current taxes and assessments for the 2007
calendar year; (ii) parties in possession of the Real Property under unrecorded leases as tenants only, with no right or option to purchase all or any portion of the Property (as such leases are described on the attached Exhibit C);
and (iii) matters or facts that a correct survey would disclose. If Buyer fails to deliver Buyers Title Notice to Seller prior to the expiration of the Feasibility Period, Buyer shall be deemed to have disapproved the Title Documents and
this Agreement shall automatically terminate in accordance with the provisions of Paragraph 7.3 hereof. Seller shall execute at Closing an Owners Affidavit and any other documents, undertakings or agreements reasonably required by the
Title Company to issue the Approved Title Policy in accordance with the provisions of this Agreement.

3.1.3 Sellers Title
Notice. Within five (5) calendar days after receiving Buyers Title Notice, if any, Seller shall deliver to Buyer written notice (Sellers Title Notice) of those Title Defects which Seller covenants and agrees
either to eliminate or cure to Buyers satisfaction by the Closing Date and those Title Requirements which Seller agrees to satisfy by the Closing Date. Sellers failure to deliver Sellers Title Notice to Buyer within the time period
specified above shall be deemed to constitute Sellers election not to eliminate or cure any such Title Defect or to satisfy any such Title Requirements. If Seller elects (or is deemed to have elected) not to eliminate or cure any Title Defects
or not to satisfy any Title Requirements, then Buyer shall have the right, by written notice delivered to Seller within four (4) calendar days after receipt of Sellers Title Notice or within four (4) calendar days after the
expiration of the time period during which Seller is entitled to deliver Sellers Title Notice, whichever occurs first, either to (a) waive its prior notice as to the Title Defects which Seller has elected (or is deemed to have elected)
not to cure and those Title Requirements which Seller



-3-

has elected (or is deemed to have elected) not to satisfy or (b) terminate this Agreement as provided in Paragraphs 7.2 and 7.3 hereof. If Buyer
fails to deliver any written notice within such four (4) calendar day period, Buyer shall be deemed to have elected to terminate this Agreement pursuant to (b) above. Notwithstanding the foregoing or anything else stated to the contrary
herein, if Buyer delivers to Seller a form of title commitment acceptable to Buyer prior to the expiration of the Feasibility Period that does not set forth any requirements inconsistent with the terms of this Agreement, then, the form of Approved
Title Policy that shall be delivered to Buyer as provided in Section 3.1.2 shall be the form of title policy provided for in such title commitment delivered to Seller, together with all endorsements attached thereto.

3.1.4 Disapproval of Liens and Monetary Encumbrances. Notwithstanding anything to the contrary contained in this Agreement, Buyer disapproves all
monetary and financing liens and encumbrances (other than liens for non-delinquent real property taxes and the non-delinquent charges and assessments of Sandy City, Sandy Suburban Improvement District and the Civic Center North Neighborhood
Development Plan, if any). Seller covenants to cause all such liens to be eliminated at Sellers sole cost and expense (including all prepayment penalties and charges) prior to or concurrently with the Close of Escrow.

3.2 GENERAL FEASIBILITY.

at Sellers office in Salt Lake City or at the Property location, as part of the Available Documents, the documents which are described on Exhibit J attached hereto, to the extent in existence and in Sellers possession

The originals (and where originals are not available, copies) of all Property Documents shall become the property of Buyer upon Close of Escrow, to the
extent not also including property other than the Property. To the extent that the Property Documents include property other than the Property, Seller shall only be obligated to deliver to Buyer legible photocopies of the portion(s) of the Property
Documents pertaining to the Property. Subject to the immediately preceding sentence, upon Close of Escrow, Seller may retain copies of any Property Documents which Seller may make at Sellers sole cost and expense.

delivers a Non-Feasibility Notice for the Property this Agreement shall automatically terminate in accordance with the provisions of Paragraph 7.3 hereof. If Buyer delivers a Feasibility Notice with respect to the Property prior to expiration
of the Feasibility Period, this Agreement shall continue in effect in accordance with its terms.

Closing, Seller will be deemed to be able to terminate all Service Contracts at Closing of which Buyer gave Seller notice of Buyers desire to terminate. If Seller so notifies Buyer of any Service Contracts that cannot be terminated by Seller
at Closing, Buyer may, within five (5) business days thereafter, terminate this Agreement in accordance with the provisions of Paragraph 7.3 hereof or, failing to do so, shall be deemed to have elected to assume such Service Contracts
that cannot be terminated. Buyer will assume the obligation to pay for all services provided under the Service Contracts on and after the Closing Date under those Service Contracts that are not in default as of the Closing Date and which Buyer has
elected (or is deemed to have elected) to assume. Seller shall terminate at Closing all Service Contracts that are not so assumed. Seller shall terminate at Closing, and Buyer shall not assume, any property management or leasing agreement affecting
the Property.

7. TERMINATION OF THIS AGREEMENT; DEFAULT BY BUYER AND SELLER.

7.1 FAILURE TO CLOSE BY CLOSING DATE. If Escrow fails to close on the Closing Date due to the failure of Seller or Buyer to satisfy their respective obligations hereunder, then, at the election of the non-defaulting
party, such non-defaulting party shall be entitled to exercise the remedies set forth below in this Paragraph 7.

7.2 FAILURE OF A
CONDITION. Except in those instances where Escrow automatically terminates under the terms of this Agreement, if any condition is not satisfied or waived within the time period and in the manner set forth in this Agreement, then the party for whose
benefit the



-9-



---

condition exists (as provided inParagraphs 4 and 5 of this Agreement) may terminate this Agreement by delivering written notice to the other party
and to Escrow Holder after the end of the applicable time period but prior to the Close of Escrow.

7.3 CONSEQUENCES OF TERMINATION. If
this Agreement terminates (or is properly terminated by either party) as specifically provided by its terms, then each of the following shall occur: Escrow shall be deemed automatically canceled regardless of whether cancellation instructions are
signed; and, except as provided to the contrary in Paragraph 7.5 hereof (concerning Sellers right to retain the Deposit as liquidated damages), Escrow Holder shall return all funds (including, without limitation, the Deposit to Buyer)
and documents then held in Escrow to the party depositing the same, and neither party shall have any claim against the other by reason of this Agreement (other than as specifically set forth below or as provided by law for breach of this Agreement,
subject to Paragraph 7.5 hereof). Notwithstanding anything to the contrary in this Agreement, if this Agreement terminates or Close of Escrow fails to occur, for any reason other than Buyers default under this Agreement, the Deposit

7.5 DEFAULT BY BUYER AND SELLER.

7.5.1
Default by Buyer. IF BUYER FAILS TO PURCHASE THE PROPERTY WHEN IT IS OBLIGATED TO DO SO UNDER THE TERMS OF THIS AGREEMENT, SELLER, AS ITS SOLE AND EXCLUSIVE REMEDY, SHALL BE ENTITLED TO RETAIN THE DEPOSIT AS LIQUIDATED DAMAGES.
BUYER AND SELLER AGREE THAT BASED UPON THE CIRCUMSTANCES NOW EXISTING, KNOWN AND UNKNOWN, IT WOULD BE IMPRACTICAL OR EXTREMELY DIFFICULT TO ESTABLISH SELLERS DAMAGES BY REASON OF SUCH DEFAULT BY BUYER. ACCORDINGLY, BUYER AND SELLER AGREE THAT
IN THE EVENT OF SUCH DEFAULT BY BUYER UNDER THIS AGREEMENT, IT WOULD BE REASONABLE AT SUCH TIME TO AWARD SELLER THE DEPOSIT AS LIQUIDATED DAMAGES. IN CONSIDERATION OF THE RIGHT TO RECEIVE PAYMENT OF THE LIQUIDATED DAMAGES, SELLER WILL BE DEEMED TO
HAVE WAIVED ALL OF ITS CLAIMS AGAINST BUYER FOR DAMAGES OR RELIEF AT LAW OR IN EQUITY. CONSEQUENTLY, THE LIQUIDATED DAMAGES SHALL BE SELLERS SOLE AND EXCLUSIVE REMEDY IN LIEU OF ANY OTHER RELIEF, RIGHT OR REMEDY, AT LAW AND IN EQUITY, TO WHICH
SELLER MIGHT OTHERWISE BE ENTITLED BY REASON OF BUYERS DEFAULT, EXCEPT AS SET FORTH IN PARAGRAPH 13.2 HEREOF. SELLER AND BUYER ACKNOWLEDGE THAT THEY HAVE READ AND UNDERSTAND THE PROVISIONS OF THIS PARAGRAPH 7.5.1 AND BY THE INITIALS OF
THEIR REPRESENTATIVES IMMEDIATELY BELOW AGREE TO BE BOUND BY ITS TERMS.

7.5.2 Default by Seller. If the Seller defaults on its obligations to sell and convey the
Property to Buyer pursuant to this Agreement, Buyer shall be entitled to do either of the



-10-



---

following as its sole and exclusive remedy: (a) terminate this Agreement and receive a refund of the Deposit, and, if such breach was a voluntary breach
by Seller, Buyer shall also be entitled to receive all actual documented out-of-pocket costs and expenses incurred by Buyer in connection with this transaction, in an amount not to exceed Fifty Thousand Dollars ($50,000); or (b) receive
specific performance from Seller.

8. GENERAL ESCROW PROVISIONS.

8.1 ESCROW INSTRUCTIONS. This Agreement when signed by Buyer and Seller shall also constitute Escrow Instructions to Escrow Holder.

8.2 OPENING OF ESCROW. When both (a) this Agreement, fully signed, or in signed counterparts, and (b) the Deposit have been delivered to Escrow
Holder, Escrow shall be deemed open (Opening of Escrow), and Escrow Holder shall immediately notify Buyer and Seller by telephone and in writing of the date of Opening of Escrow.

8.3 GENERAL PROVISIONS. Notwithstanding anything to the contrary in this Agreement, the general provisions of Escrow Holder, if any, which are later
signed by the parties, are incorporated by reference to the extent they are not inconsistent with the provisions of this Agreement. If there is any inconsistency between the provisions of those general provisions and any of the provisions of this
Agreement, the provisions of this Agreement shall control.

8.4 PRORATIONS. Prorations for the Property shall be calculated and implemented
by Buyer and the Seller as follows:

8.4.1 Standard Prorations. Subject to Paragraphs 8.4.3 through 8.4.8 hereof, all
non-delinquent rents, expenses, expense recoveries, utility charges, common area charges, real property taxes, assessments, maintenance charges, and other revenues and costs for the Property shall be prorated as of the Close of Escrow (based on the
periods to which they relate and are applicable, and regardless of when payable).

8.4.2 Intentionally omitted.

8.4.3 Additional Rent Reconciliation. To the extent that any additional rent (including, without limitation, estimated payments for operating
expenses and/or real estate taxes) (collectively, Expenses) is paid by the Tenants to Seller under the Leases based on an estimated payment basis (monthly, quarterly, or otherwise) for which a future reconciliation of actual
Expenses to estimated payments is required to be performed at the end of a reconciliation period, Buyer and Seller shall make an adjustment at the Closing for the applicable reconciliation period based on a comparison of the actual Expenses to the
estimated payments at the Closing. If, as of the Closing, Seller has received additional rent payments in excess of the amount that the Tenants would be required to pay, based on the actual Expenses as of the Closing, Buyer shall receive a credit in
the amount of such excess. If, as of the Closing, Seller has received additional rent payments that are less than the amount that the Tenants would be required to pay based on the actual Expenses as of the Closing, Buyer shall deliver to Seller the
amount of such deficiency within thirty (30) days of the reconciliation pursuant to which the Tenants payments of such deficient amounts are received by Buyer.

8.4.4 Receivables. Buyer shall not be required to purchase Sellers accounts receivables and/or delinquent rents (including, without
limitation, any additional rent payments or other amounts payable by the Tenants under the Leases). No proration shall be made at the Closing for these



-11-



---

items. For a period of six (6) months following the Closing Date, Buyer shall continue to bill the Tenants for accounts receivable and delinquent rents
attributable to the Property for the period prior to the Closing Date. To the extent that Buyer receives, within the first six (6) months after the Closing Date, rents applicable to a period prior to the Closing, Buyer shall promptly pay such
rents to Seller after first deducting any sums due Buyer from the Tenants for rent or other charges accruing after the Closing Date. After six (6) months from the Closing Date, to the extent that Buyer has not paid to Seller accounts receivable
and/or delinquent rents owing to Seller for periods prior to the Closing Date, Seller shall be permitted to collect such accounts receivables and/or such delinquent rents directly from the Tenants after the expiration of such six (6) month
period to the extent such collections do not interfere with the Tenants tenancy. After expiration of such six (6) month period, all amounts (accounts receivables, rents, or otherwise) received by Buyer shall belong to Buyer unless the
payment of any such amount (or the correspondence accompanying such payment) specifically states that it is specifically for satisfaction of amounts attributable to a period prior to the Closing Date.

8.4.5 Security Deposits. Buyer shall be credited at Closing for the amount of all security deposits provided for under the Leases as reflected in
the rent roll provided by Seller to Buyer pursuant to Paragraph 3.2.2. hereof. Unless and until this Agreement is terminated, Seller shall not apply any security deposits reflected in the rent roll to any obligations under the Leases, except
as expressly permitted by the Lease concerned, but only to the extent that the Tenant thereunder is at least thirty (30) days delinquent on its payment obligations under such Lease. With respect to any security deposit which is evidenced by a
letter of credit, Seller shall (a) deliver to Buyer at the Closing such original letter of credit, and (b) execute and deliver at the Closing such other instruments as the issuer of such letter of credit shall reasonably require in order
to cause the named beneficiary under such letter of credit to be changed to Buyer.

8.4.6 Leasing Costs.

(a) Buyer shall be credited at Closing for the amount of all unsatisfied costs and expenses which were incurred, or are to be incurred, in connection
with any and all leases executed, modified or extended by Seller prior to the Effective Date, including, without limitation, all costs and expenses for tenant improvements (either completed or to be completed) and brokerage commissions
(collectively, Pre-Effective Date Leasing Costs). Seller shall remain responsible for satisfying any Pre-Effective Date Leasing Costs which were not credited to Buyer (but were supposed to be credited to Buyer) at Closing.

(b) Post-Effective Date Leasing Costs means all costs and expenses payable in connection with any and all leases
executed, modified or extended by Seller on or after the Effective Date, including, without limitation, all costs and expenses for tenant improvements (either completed or to be completed) and brokerage commissions to the extent (and only the
extent) that such Post-Effective Date Leasing Costs are expressly set forth in such leases, modifications or extensions and such leases, modifications or extensions have been approved by Buyer in accordance with Paragraph 11.2 below. Seller
shall be credited at Closing for the amount of any Post-Effective Date Leasing Costs paid by Seller. Buyer shall be responsible for satisfying all other Post-Effective Date Leasing Costs.

8.4.7 Capital Costs. Buyer shall be credited at Closing for the amount of all amounts which are unsatisfied amounts for all capital
contracts, contracts pertaining to works of improvement or other contracts existing prior to Closing, pertaining to the Property (regardless of when the work, services or other obligations were performed or are to be performed)
(Pre-Closing Capital Costs). Seller shall remain responsible for satisfying any Pre-Closing Capital Costs which were not credited to Buyer (but were supposed to be credited to Buyer) at Closing.

8.4.8 Delinquent Taxes and Mechanics Liens. Buyer shall receive a credit at Closing in the
amount of any delinquent taxes applicable to the Property and any non-delinquent taxes shall be prorated in accordance with Paragraph 8.4.1 above. At Closing, Seller shall cause to be released or shall bond against any mechanics and
materialmens liens encumbering the Property.

8.4.9 Tax Appeals. Seller has engaged Rob Galanis/Mountain High Properties (the
Broker) for the purpose of protesting the amount of taxes or the assessed valuation for calendar year 2007 for the Property (Protest Proceedings), with the fee (the Brokers Fee) to be
paid to the Broker in connection therewith being equal to thirty percent (30%) of any net savings resulting from the Protest Proceedings. Any reduction in the taxes originally assessed for calendar year 2007 prior to payment of such taxes or
any cash refunds or proceeds actually distributed following payment of such taxes (collectively, Tax Reduction) will be apportioned as described below. Any Tax Reduction (including interest thereon) on account of a favorable
determination, after deduction of payment of any reimbursements owing to the Tenants, shall be: (a) the property of Seller to the extent such Tax Reduction was for taxes paid by Seller applicable to a period prior to the calendar year in which
the Closing Date occurred, (b) prorated between Buyer and Seller for taxes paid or payable for the calendar year in which the Closing Date occurred, and (c) the property of Buyer for taxes payable for a period after the calendar year in
which the Closing Date occurred. Buyer shall pay the Brokers Fee directly to the Broker when due (that is, on determination or receipt of the Tax Reduction), and the Tax Reduction to be distributed or apportioned shall not be reduced by the
Brokers Fee, which shall be borne solely by Buyer. Seller shall have the obligation to refund to the Tenants as of the date of such Tax Reduction, any portion of such Tax Reduction paid to it which may be owing to the Tenants, which payment
shall be paid to Buyer within fifteen (15) business days of delivery to Seller by Buyer of written confirmation of the Tenants entitlement to such Tax Reduction. Buyer shall have the obligation to refund to the Tenants as of the date of
such Tax Reduction, any portion of such Tax Reduction paid to it which may be owing to the Tenants. Seller and Buyer agree to notify the other in writing of any receipt of a Tax Reduction within fifteen (15) business days of receipt of such Tax
Reduction. To the extent either party obtains a Tax Reduction, a portion of which is owed to the other party, the receiving party shall deliver the Tax Reduction to the other party within fifteen (15) business days of its receipt.

8.4.10 Errors and Omissions. If any errors or omissions are made regarding adjustments and prorations, the parties shall make appropriate
corrections promptly upon the discovery thereof. If any estimations are made at the Close of Escrow regarding adjustments or prorations, the parties shall make the appropriate corrections promptly when accurate information becomes available. Any
corrected adjustment or proration shall be paid in cash to the appropriate party within fifteen (15) business days after the correction or adjustment. Notwithstanding anything to the contrary in this Paragraph, any right to a correction or
adjustment shall terminate one (1) year after Close of Escrow, except with regard to Pre-Effective Date Leasing Costs, Post-Effective Date Leasing Costs, Pre-Closing Capital Costs, and any Tax Reduction received with regard to any Protest
Proceedings.

8.5 PAYMENT OF COSTS.

(a) Seller shall pay for (i) one-half (1/2) of the Escrow fees and charges, (ii) all title insurance costs and fees related to the standard coverage owners policy (only) (meaning with

transaction. Concurrently with the Close of Escrow, Seller shall be responsible for paying to Broker all brokerage commissions payable to Broker pursuant to a separate agreement between Seller and Broker. Except for the Broker, it is understood that
neither Seller nor Buyer has engaged any other broker or finder in connection with this transaction. Seller shall indemnify, defend and hold harmless Buyer from and against all claims, liabilities, costs, damages and expenses, (including, without

Buyer elects to continue with this transaction, as provided above, then the Casualty proceeds from the carrier shall become the property of Buyer after Close
of Escrow (however, Buyer shall receive a credit at Closing for the amount of any deductible, self-insured amount or uninsured amount). Seller agrees to execute all documents necessary in order to effectuate such transfer of any Casualty proceeds to
Buyer.

13. GENERAL PROVISIONS.

13.1 ASSIGNMENT.

13.1.1 Successors and Assigns. This Agreement shall be binding upon and shall
inure to the benefit of Buyer and Seller and their respective successors and assigns.

13.1.2 Right to Assign. Buyer shall have the
right to assign its rights and obligations under this Agreement to an entity that is a real estate investment trust (REIT) (or that is wholly owned directly or indirectly by a REIT) for which Buyer or an affiliate of Buyer acts as
the investment advisor on prior or concurrent written notice to Seller, which notice shall be accompanied by a legible photocopy of the fully-executed assignment and assumption instrument effecting such assignment, but without the prior written
consent of Seller. However, Buyer shall not be relieved of its obligations under this Agreement by such assignment or nomination until Close of Escrow. If Buyers assignee or nominee has satisfied all of Buyers obligations under this
Agreement as of the Closing Date (including, without limitation, the payment of the Purchase Price to Seller, subject to permitted prorations and adjustments), and has signed a written assumption of all of Buyers obligations under this
Agreement, Buyer (but not the assignee) shall automatically be released from any further obligations or responsibilities under this Agreement upon Close of Escrow.

13.2 ATTORNEYS FEES AND/OR COSTS. In any action or proceeding between the parties to enforce or interpret any of the terms or provisions of this Agreement, the prevailing party in the action or proceeding shall
be entitled to, in addition to damages, injunctive relief or other relief (subject to the limitations set forth in this Agreement), its reasonable costs and expenses, including, without limitation, costs and reasonable attorneys fees, both at
trial and on appeal.

13.3 NOTICES AND APPROVALS.

(a) All notices, approvals or other communications (collectively, Notices) required or permitted under this Agreement shall be in writing, and shall be sent by one or more of the following:
(i) personally delivered, (ii) sent by overnight mail (Federal Express or the like), (iii) sent by registered or certified mail, postage prepaid, return receipt requested, or (iv) sent by facsimile (provided that a follow-up hard
copy of the facsimile is sent the same day by one of the other above methods within two (2) business days after the transmission).

(b) Notices shall be deemed received upon the earlier of (i) if personally delivered, the day of delivery, to the address of the person to receive such Notice, (ii) if sent by overnight mail, the business day following its deposit
in such overnight facility, (iii) if mailed, two (2) business days after the date of posting by the United State Post Office, or (iv) if by facsimile, the date of transmission. If multiple methods of providing notice have been used,
the earlier date of deemed notice shall govern. In order to be effective, all Notices must be directed to the appropriate parties as follows.

valid and enforceable to the fullest extent permitted by law.

written consent of the other party; provided, however that each party shall have the right to make such disclosures as required by law and as are needed for the transaction to occur (i.e. consultants, lenders, capital sources, etc). Notwithstanding
the foregoing, nothing contained herein shall impair Buyers (or its permitted assignees) right to disclose information relating to this Agreement or the Property (a) 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 Buyer or its permitted assignees, (b) in connection with any filings (including any amendment or supplement to any S-11 filing) with
governmental agencies (including the SEC) by any REIT holding an interest (direct or indirect) in any permitted assignee of Buyer, and (c) to any broker/dealers in the REITs broker/dealer network and any of the REITs investors.

survive the Close of Escrow and the execution and delivery of the Deed (and shall not be merged with the recording of the Deed) for a period of nine (9) months only, at which time such covenants, obligations, representations and agreements
shall automatically terminate and have no further force or effect unless a lawsuit has been filed by Buyer against Seller within such nine (9) month period.
