when due, said deposit may, at the opinion of the Landlord (but Landlord shall
not be required to), be applied to any rent due and unpaid, and if the Tenant
violates any of the other terms, covenants and conditions of this lease, said
deposit shall be applied to any damages suffered by Landlord as a result of
Tenant's default to the extent of the amount of the damages suffered.

construed as waiving any of the Landlord's other remedies as provided herein, or
by law. If the security deposit is applied by Landlord for the payment of over
due rent or other sums due and payable to Landlord by Tenant hereunder, then
Tenant shall, on the written demand of Landlord, forthwith remit to Landlord a

demand, shall constitute a breech of this lease. Should Tenant comply with all
of the terms, covenants and conditions of this Lease and promptly pay all of the
rental herein provided for as it falls due, and all other sums payable by Tenant
to Landlord hereunder, said security deposit shall be returned in full to Tenant
at the end of the term of this lease, or upon the earlier termination of this
lease pursuant to the provisions hereof, except in the event that the demised
premises are sold as a result of the exercise of any power of sale under any
mortgage or deed of trust, in which event the lease shall be automatically
amended to delete any reference to this paragraph, and Tenant shall be entitled
to immediate reimbursement of its security deposit from the party then holding
said deposit.

charges until after the termination of this Lease shall relieve Tenant of the
obligation to make such payments. Payment of such taxes shall be made by Tenant
to Landlord not later than thirty (30) days following the date on which Landlord
provides Tenant with written evidence of such taxes in the form of a copy of the
tax return or notice. If Tenant fails to pay any of such taxes, charges or other
impositions when due, Landlord may pay the same under the provisions of'
paragraph 19, hereinafter set forth. Anything herein to the contrary
notwithstanding, if Tenant deems excessive or illegal any such tax or
assessment, Tenant may defer payment thereof so long as the validity or the
amount thereof is contested by Tenant in good faith, in which case Tenant shall

harmless Landlord of and from any and all claims of any kind or nature arising
from Tenant's use of the demised premises during the term hereof, and Tenant

               combined limit of bodily injury and property damage
               liability of not less than $1,000,000.00.

          Such insurance may, at Tenant's election, be carried under any general
blanket coverage of Tenant. A renewal policy shall be procured not less than ten

certified copy thereof, or a satisfactory certificate of the insurer evidencing
insurance carried with proof of payment of the premium shall be deposited with

should it be necessary for Landlord to restore or cause to be restored the
premises to the same condition as when said premises were delivered to Tenant.

          16. HOLDOVER: Should the Landlord permit Tenant to holdover the leased
premises or any part thereof, after the expiration of the term of this Lease,
then and unless otherwise agreed in writing, such holding over shall constitute
a tenancy from month-to-month only, and shall in no event be construed as a
renewal of this Lease and all provisions of this Lease not inconsistent with a
tenancy from month-to-month shall remain in full force and effect. During the
month-to-month tenancy, Tenant agrees to give Landlord thirty (30) days prior
written notice of its intent to vacate premises. Tenant agrees to vacate the

performance for Tenant and for the purpose advance such amounts as may be
necessary. Any amounts so advanced, or any expense incurred, or sum of money
paid by Landlord by reason of the failure of Tenant to comply with any covenant
agreement, obligation or provision of this Lease, or in defending any action to
which Landlord may be subjected by reason of any such failure for any reason of
this Lease, shall be deemed to be additional rent for the leased premises and
shall be due and payable to Landlord on demand. The acceptance by Landlord of
any installment of fixes rent, or of any additional rent due under this or any
other paragraph of this lease, shall not be a waiver of any other rent then due
nor of the right to demand the performance of any other obligation of the Tenant
under this Lease. Interest shall be paid to Landlord on all sums advanced by
Landlord at an annual interest rate of 2% over the prime rate charged by First
Security Bank of Utah.

conditions of this Lease (other than the covenants for the payment of rent or

days after notice, then Landlord may, at its option, terminate this Lease by
giving Tenant written notice of such termination and, thereupon, this Lease
shall expire as fully and completely as if that day were the date definitely

surrender the leased premises.

the payment of the rent reserved hereunder, or any part thereof, or in making

file a voluntary petition in bankruptcy or if Tenant shall file any petition or
institute any proceedings under any insolvency or Bankruptcy Act or any
amendment thereto hereafter made, seeking to effect its reorganization or a
composition with its creditors, or if any proceedings based on the insolvency of
Tenant or relating to bankruptcy proceedings, a receiver or trustee shall be
appointed for Tenant or if any proceedings shall be commenced for the
reorganization of Tenant or if Tenant shall admit in writing its inability to
pay its obligations generally as they become due, then Landlord, in addition to
any other rights or remedies it may have, shall have the immediate right of
re-entry and may remove all persons and property from the premises. Such
property may be removed and stored in a public warehouse or elsewhere at the
cost of and for the account of Tenant. Landlord may elect to re-enter, as herein
provided, or Landlord may take possession pursuant to this Lease and relet said
premises or any part thereof for such term or terms (which may be for a term
extending beyond the term of this Lease) and at such rental or rentals and upon
such other terms and conditions as Landlord in the exercise of Landlord's sole
discretion may deem advisable with the right to make repairs to said premises.

Landlord, in addition to any indebtedness due hereunder, the costs and expenses
of such reletting including advertising costs, brokerages fees, any reasonable
attorney's fees incurred and the cost of such repairs incurred by Landlord, and
the amount, if any, by which the rent reserved in this Lease for the period of
such reletting (up to but not beyond the term of this Lease) exceeds the amount
agreed to be paid as rent for the premises for said period by such reletting
and; provided, however, that such reletting is made in good faith and or an
arm's-length basis. If Tenant has been credited with any rent to be received by
such reletting and such rents shall not be promptly paid to Landlord by the new
Tenant, such deficiency shall be calculated and promptly paid monthly by Tenant.
No such re-entry or taking possession of the premises by Landlord shall be
construed as an election by Landlord to terminate this Lease unless the
termination thereof be decreed by a court of competent jurisdiction or stated
specifically by the Landlord in writing addressed to Tenant. Should Landlord at
any time terminate this Lease for any breach, in addition to any other remedy
Landlord may have, Landlord may recover from Tenant all damages Landlord may
incur by reason of such breach, including the cost of recovering the premises
including reasonable attorney's fees, court costs, and storage charges. In no
event, shall this Lease or any rights or privileges hereunder be an asset of
Tenant under any bankruptcy, insolvency or reorganization proceedings.

this Lease by suit or otherwise, the party at fault shall pay the costs and
expenses incident thereto, including a reasonable attorney's fee.

          22. MEDIATION AND ARBITRATION: If any dispute or claim in law or
equity arises out of this Lease, Tenant and Landlord agree in good faith to
attempt to settle such dispute or claim by mediation under the Commercial
Mediation rules of the American Arbitration Association. If such mediation is
not successful in resolving such dispute or claim, then such dispute or claim
shall be decided by neutral binding arbitration before a single arbitrator in
accordance with the Commercial Arbitration rules of the American Arbitration
Association. Judgment upon the award rendered by the arbitrator may be entered
in any court having jurisdiction thereof. However, this paragraph does not apply
to disputes or claims arising under Section 78, Chapter 36, of the Utah Code.

          23. FAILURE TO PERFORM COVENANT: Any failure on the part of either
party to this Lease to perform any obligations hereunder, other than Tenant's
obligation to pay rent, and any delay in doing any act required hereby shall be
excused if such failure or delay is caused by any strike, lockout, governmental
restriction or any similar cause beyond the control of the party so failing to
perform, to the extent and for the period that such continues.

          24. RIGHTS OF SUCCESSORS AND ASSIGNS: The covenants and agreements

nothing herein contained shall prevent Tenant, in good faith and for good cause
from contesting the claim or claims of any person, firm or corporation growing

Tenant on the said premises, and the postponement of payment of such claim or
claims, until such contest shall finally be decided shall not be a violation of
this Lease or any covenant thereof. Should any such lien be filed and not
released or discharged or action not commenced to declare the same invalid
within thirty (30) days after discovery of the same by Tenant, Landlord may at
Landlord's option (but without any obligation so to do) pay and discharge such
lien and may likewise pay and discharge any taxes, assessments or other charges
