GRANT. For the purposes of and upon the terms and conditions in this Deed of Trust, Trustor IRREVOCABLY GRANTS, CONVEYS AND ASSIGNS TO TRUSTEE, IN TRUST FOR THE BENEFIT OF BENEFICIARY, WITH POWER OF SALE AND RIGHT OF ENTRY AND POSSESSION, all of that real property located in the City of ▇▇▇▇▇, County of Salt Lake, State of Utah, described on Exhibit A attached hereto (“Land”), together with all right, title, interest, and privileges of Trustor in and to all streets, ways, roads, and alleys used in connection with or pertaining to such real property and any improvements thereon, all development rights or credits, air rights, water, water rights and water stock related to the real property, all timber, and all minerals, oil and gas, and other hydrocarbon substances in, on or under the real property, and all licenses, appurtenances, reversions, remainders, easements, rights and rights of way appurtenant or related thereto; any and all rights of Trustor, as a declarant, under any covenants, conditions, and restrictions now or hereafter pertaining to the real property described on Exhibit A, hereto, provided, however, that Beneficiary shall have no liability under such covenants, conditions, and restrictions unless and until Beneficiary forecloses on the real property; all buildings, other improvements and fixtures now or hereafter located on the real property, including, but not limited to, all apparatus, equipment, and appliances used in the operation or occupancy of the real property, it being intended by the parties that all such items shall be conclusively considered to be a part of the real property, whether or not attached or affixed to the real property (the “Improvements”); all interest or estate which Trustor may hereafter acquire in the property

described above, and all additions and accretions thereto, and the proceeds of any of the foregoing; (all of the foregoing being collectively referred to as the “Subject Property”). The listing of specific rights or property shall not be interpreted as a limit of general terms.

COVENANTS. Trustor covenants and agrees at Trustor’s sole cost and expense to: (a) perform the obligations of lessor contained in the Leases and enforce by all appropriate remedies performance by the lessees of the obligations of the lessees contained in the Leases; (b) give Beneficiary prompt written notice of any material default which occurs with respect to any of the Leases, whether the default be that of the lessee or of the lessor; (c) exercise Trustor’s best efforts to keep all portions of the Subject Property that are capable of being leased at rental rates pursuant to the terms of the Loan Agreement; (d) deliver to Beneficiary fully executed, copies of each and every Lease that it is required to deliver in accordance with the Loan Agreement; and (e) execute and record such additional assignments of any Lease or, if required by the terms of the Loan Agreement, use commercially reasonable effort to obtain specific subordinations (or subordination, attornment and non-disturbance agreements executed by the lessor and ▇▇▇▇▇▇) of any Lease

to the Deed of Trust, in form and substance acceptable to Beneficiary, as Beneficiary may request. Trustor shall not, without Beneficiary’s prior written consent or as otherwise permitted by any provision of the Loan Agreement: (i) to the extent prohibited by the terms of the Loan Agreement, enter into any Leases after the date hereof; (ii) execute any other assignment relating to any of the Leases; (iii) to the extent prohibited by the terms of the Loan Agreement, discount any rent or other sums due under the Leases or collect the same in advance, other than to collect rentals one (1) month in advance of the time when it becomes due; (iv) to the extent prohibited by the terms of the Loan Agreement, terminate, modify or amend any of the terms of the Leases or in any manner release or discharge the lessees from any obligations thereunder; (v) to the extent prohibited by the terms of the Loan Agreement, consent to any assignment or subletting by any lessee; or (vi) subordinate or agree to subordinate any of the Leases to any other deed of trust or encumbrance. Any such attempted action in violation of the provisions of this Section 3.5 shall be null and void. Without in any way limiting the requirement of Beneficiary’s consent hereunder, any sums received by Trustor in consideration of any termination (or the release or discharge of any lessee) modification or amendment of any Lease shall be applied as set forth in the Loan Agreement.

This Deed of Trust constitutes a security agreement and a financing statement (fixture filing) and it is hereby recited (to the extent that such recitation is required by Utah Code Annotated § 70A-9a-502 (or any replacement statute) because any portion of the Subject Property and the Collateral may

constitute fixtures) that this Deed of Trust is to be filed in the office where a mortgage on the Land would be recorded, which is the office of the Recorder of Salt Lake County, Utah. Trustor is the record owner of the Land. A carbon, photographic or other reproduced copy of this Deed of Trust and/or any financing statement relating hereto shall also be sufficient for filing and/or recording as a financing statement.

TAX AND INSURANCE IMPOUNDS. At any time following the occurrence of a Default, at Beneficiary’s option and upon its demand, but subject to Trustor’s right to use cash from the Property to cover Permitted REIT Distributions (as such term is defined in the Loan Agreement), Trustor shall, until all Secured Obligations have been paid in full, pay to Beneficiary monthly, annually or as otherwise directed by Beneficiary an amount estimated by Beneficiary to be equal to: (a) all taxes, assessments, levies and charges imposed by any public or quasi-public authority or utility company which are or may become a lien upon the Subject Property or Collateral and will become due for the tax year during which such payment is so directed; and (b) premiums for fire, hazard and insurance required or requested pursuant to the Loan Documents when same are next due. If Beneficiary determines that any amounts paid by Trustor are insufficient for the payment in full of such taxes, assessments, levies, charges and/or insurance premiums, Beneficiary shall notify Trustor of the increased amounts required to pay all amounts when due, whereupon Trustor shall pay to Beneficiary within thirty (30) days thereafter the additional amount as stated in Beneficiary’s notice. All sums so paid shall not bear interest, except to the extent and in any minimum amount required by law; and Beneficiary shall, unless Trustor is otherwise in Default hereunder or under any Loan Document, apply said funds to the payment of, or at the sole option of Beneficiary release said funds to Trustor for the application to and payment of, such sums, taxes, assessments, levies, charges, and insurance premiums. Upon Default by Trustor hereunder or under any Loan Document, Beneficiary may apply all or any part of said sums to any Secured Obligation and/or to cure such Default, in which event Trustor shall be required to restore all amounts so applied, as well as to cure any other events or conditions of Default not cured by such application. Upon assignment of this Deed of Trust, Beneficiary shall have the right to assign in writing all amounts collected and in its possession to its assignee whereupon Beneficiary and the Trustee shall be released from all liability with respect thereto. Within ninety-five (95) days following full repayment of the Secured Obligations (other than full repayment of the Secured Obligations as a consequence of a foreclosure or conveyance in lieu of foreclosure of the liens and security interests securing

the Secured Obligations) or at such earlier time as Beneficiary may elect, the balance of all amounts collected and in Beneficiary’s possession shall be paid to Trustor and no other party shall have any right or claim thereto.

Beneficiary shall permit insurance or condemnation proceeds held by Beneficiary to be used for repair or restoration but may condition such application upon reasonable conditions, including, without limitation: (i) the deposit with Beneficiary of such additional funds which Beneficiary determines are needed to pay all costs of the repair or restoration, (including, without limitation, taxes, financing charges, insurance and rent during the repair period); (ii) the establishment of an arrangement for lien releases and disbursement of funds acceptable to Beneficiary; (iii) the delivery to Beneficiary of plans and specifications for the work, a contract for the work signed by a contractor acceptable to Beneficiary, a cost breakdown for the work and a payment and performance bond for the work, all of which shall be acceptable to Beneficiary; and (iv) the delivery to Beneficiary of evidence acceptable to Beneficiary (aa) that after completion of the work the income from the Subject Property will be sufficient to pay all expenses and debt service for the Subject Property; (bb) of the continuation of Leases acceptable to and required by Beneficiary; (cc) that upon completion of the work, the size, capacity and total value of the Subject Property will be at least as great as it was before the damage or condemnation occurred; (dd) that there has been no material adverse change in the financial condition or credit of Trustor since the date of this Deed of Trust; (ee) no Default shall have occurred, and (ff) of the satisfaction of any additional conditions that Beneficiary may reasonably establish to protect its security. Trustor hereby acknowledges that the conditions described above are

reasonable, and, if such conditions have not been satisfied within sixty (60) days of receipt by Beneficiary of such insurance or condemnation proceeds, then Beneficiary may apply such insurance or condemnation proceeds to pay the Secured Obligations in such order and amounts as Beneficiary in its sole discretion may choose.

Trustor shall pay Trustee’s fees and reimburse Trustee for expenses in the administration of this trust, including attorneys’ fees. Trustor shall pay to Beneficiary reasonable compensation for services rendered concerning this Deed of Trust, including without limit any statement of amounts owing under any Secured Obligation. Beneficiary shall not directly or indirectly be liable to Trustor or any other person as a consequence of (i) the exercise of the rights, remedies or powers granted to Beneficiary in this Deed of Trust; (ii) the failure or refusal of Beneficiary to perform or discharge any obligation or liability of Trustor under any agreement related to the Subject Property or Collateral or under this Deed of Trust; or (iii) any loss sustained by Trustor or any third party resulting from Beneficiary’s failure (whether by malfeasance, nonfeasance or refusal to act) to lease the Subject Property after a Default (hereinafter defined) or from any other act or omission (regardless of whether same constitutes negligence) of Beneficiary in managing the Subject Property after a Default unless the

loss is caused by the gross negligence or willful misconduct of Beneficiary and no such liability shall be asserted against or imposed upon Beneficiary, and all such liability is hereby expressly waived and released by Trustor.

Trustor shall not make or commit to make any Transfer without Beneficiary’s prior written consent, which it may grant or withhold at its sole discretion (except with respect to those Transfers reasonably approved by Beneficiary or otherwise expressly permitted under Sections 8.1(a), 8.1(b) and 8.4(a) and (b) of the Loan Agreement). It is expressly agreed that Beneficiary may predicate Beneficiary’s decision to grant consent to a Transfer on such terms and conditions as Beneficiary may require, in Beneficiary’s sole discretion, including without limitation (i) consideration of the creditworthiness of the party to whom such Transfer will be made and its development and management ability with respect to the Subject Property, (ii) consideration of whether the security for repayment, performance and discharge of the Secured Obligations, or Beneficiary’s ability to enforce its rights, remedies, and recourses with respect to such security, will be impaired in any way by the proposed Transfer, (iii) an increase in the rate of interest payable under the Note or any other change in the terms and provisions of the Note and other Loan Documents, (iv) reimbursement of Beneficiary for all costs and expenses incurred by Beneficiary in investigating the creditworthiness and management ability of the party to whom such Transfer will be made and in determining whether Beneficiary’s security will be impaired by the proposed Transfer, (v) payment to Beneficiary of a transfer fee to cover the cost of documenting the Transfer in its records, (vi) payment of Beneficiary’s reasonable attorneys’ fees in connection with such Transfer, (vii) endorsements (to the extent available under applicable law) to any existing mortgagee title insurance policies or construction binders insuring Beneficiary’s liens and security interests covering the Subject Property, and (viii) require additional security for the payment, performance and discharge of the Secured Obligations. If Beneficiary’s consent should be given, any Transfer shall be subject to the Loan Documents and any transferee of Trustor’s interest shall: (i) assume all of Trustor’s obligations thereunder; and (ii) agree to be bound by all provisions and perform all obligations contained therein; provided, however, that such assumption shall not release Trustor or any maker or any guarantor of the Note from any liability thereunder or under any other Loan Documents without the prior written consent of Beneficiary. In the event of any Transfer without the prior written consent of Beneficiary, whether or not Beneficiary elects to enforce its right to accelerate the Loan pursuant to Sections 6.1 and 6.2, all sums owing under the Note, as well as all other charges, expenses and costs owing under the Loan Documents, shall at the option of Beneficiary, automatically bear interest at five percent (5%) above the rate provided in the Note, from the date (or any date thereafter) of such unconsented to Transfer. Trustor acknowledges that the

automatic shift(s) to this alternate rate is reasonable since the representations that Beneficiary relied upon in making the Loan may no longer be relied upon. A consent by Beneficiary to one or more Transfers shall not be construed as a consent to further Transfers or as a waiver of Beneficiary’s consent with respect to future Transfers.

DEFAULT. For all purposes hereof, the term “Default” shall mean (a) the existence of any Event of Default as defined in the Loan Agreement; (b) at Beneficiary’s option, the failure of Trustor to make any payment of principal or interest on the Note or to pay any other amount due hereunder or under the Note when the same is due and payable, whether at maturity, by acceleration or otherwise; (c) the failure of Trustor to perform any non-monetary obligation hereunder, or the failure to be true of any representation or warranty of Trustor contained herein and the continuance of such failure for ten (10) days after notice, or within any longer grace period, if any, allowed in the Loan Agreement for such failure, or (d) if Trustor or any other Person shall make

a Transfer without the prior written consent of Beneficiary (which consent may be withheld in Beneficiary’s sole discretion (except for those Transfers reasonably approved by Beneficiary or otherwise expressly permitted under Sections 8.1(a), 8.1(b), 8.4(a) and (b) of the Loan Agreement) or conditioned as provided in Section 5.13).
