            ARTICLE I BASIC LEASE PROVISIONS; ENUMERATION OF EXHIBITS

         Suite 300, Salt Lake City, UT 84109

(D)      TENANT: SENTO CORPORATION, a Utah corporation

(E)      ADDRESS OF TENANT FOR NOTICES (Section 16.01). 732 East Utah Valley

(G)      TENANT'S TRADE NAME (Exhibit "E" - Sign Criteria): Sento

(H)      BUILDING (Section 2.01): Situated as shown on Exhibit "A" attached
         hereto in the Utah Valley Business Park, American Fork City, Utah
         County, State of Utah. Mailing address will be determined prior to
         occupancy. The Building is located on a lot containing 114 parking
         spaces.

(I)      PREMISES (Section 2.01): That portion of the building to be
         constructed, consisting of approximately 15,370 sq. ft. of gross
         rentable area to be mutually agreed between Landlord and Tenant.

(J)      DELIVERY OF POSSESSION (Section 5.03): June 30, 2000

(K)      RENTAL TERM, COMMENCEMENT AND EXPIRATION DATE (Sections 4.01 & 4.02):
         The Rental Term shall commence on the date Tenant receives possession
         of the Leased Premises and shall be for a period of sixty (60) full
         calendar months plus any initial partial calendar month, subject to
         Tenant's option to terminate effective at the end of the third (3rd)
         Lease Year as set forth in Section 1.01 (V).

(L)      BASE MONTHLY RENT (Section 3.01): Seventeen Thousand One Hundred
         Seventy One and 38/100 ($17,171.38) per calendar month. (Annual Rent:
         $206,056.56.) The initial base rent has been calculated based on a Net
         Rent of $11.00 per square foot plus $36,986.64 as Tenant's share of
         estimated Operating Expenses for the First Lease Year. To the extent
         that Landlord's actual remodeling construction costs exceed $107,590,
         the excess shall be divided by 15,370 to get an "Excess Cost Per Square
         Foot." Said Excess Cost Per Square Foot shall be multiplied by $.16 and
         the product shall constitute the increase in Annual Base Rent, which
         increase shall be divided by twelve (12) to calculate the increase in
         Monthly Base Rent.

(M)      ANNUAL ADJUSTMENTS IN BASE MONTHLY RENT (Section 3.02): The base
         monthly rent shall be adjusted annually to reflect 1) any increase or
         decrease in Tenant's Share of Budget Operating Expense as determined
         pursuant to Section 1.01 (N); and 2) an increase of $704.46 monthly to
         reflect a five percent (5%) increase in the Net Rent portion effective
         July 1, 2002.

<PAGE>

(N)      BUDGETED OPERATING EXPENSES (Section 3.03): $36,986.64 during the First
         Lease Year based on 62.28% Operating Expense Budget attached hereto as
         Exhibit "F." Operating Expenses shall exclude electrical and gas
         utility expenses relating specifically to the Leased Premises, but
         shall include electricity for parking lot and exterior lighting which
         is monitored by an outside electrical submeter. Annually thereafter, on
         or before June 1, Tenant and Landlord shall mutually agree on a
         reasonable Operating Expense Budget for the upcoming Lease Year, based
         on past history and reasonably anticipated costs. The Base Monthly Rent
         payable during the upcoming Lease Year shall be increased or decreased
         by 1/12th of the difference between $36,986.64 and the Operating
         Expense Budget.

(O)      TENANT'S SHARE OF OPERATING EXPENSES (Section 3.03): 62.68 percent
         (62.68%) of all operating expenses as defined in Section 3.03 and
         Section 1.01 (N) above, which percentage has been adjusted to reflect
         an assumed 95% occupancy for the Building and is calculated as follows.
         .95 x 25,812 sq. ft. = 24,521.4 sq. ft.; 15,370 sq. ft./24,521.4 sq.
         ft. = 62.68%.

(P)      LANDLORD'S CONSTRUCTION CONTRIBUTION (Section 5.01 and Section 6.02):
         Landlord shall pay the costs of remodeling the Leased Premise in
         accordance with mutually agreed plans and specifications except that
         Tenant shall pay the costs of data and telephone wiring and Tenant's
         equipment. The Base Monthly Rent has been calculated based on a
         Landlord Contribution of $107,590. To the extent that Landlord's actual
         construction cost exceeds $107,590, the Base Monthly Rent shall be
         adjusted as set forth in Section 1.01 (L).

(Q)      PREPAID RENT: $ None paid upon execution of this Lease to be applied to
         the first installment(s) of Base Monthly Rent due hereunder.

(U)      BUILDING STANDARD OPERATING HOURS (Article XII): The standard hours of
         operation for the Building shall be 7:00 a.m. to 6:00 p.m. Monday
         through Friday and 8:00 a.m. to 12:00 Noon on Saturday, excluding
         holidays. Tenant shall have access and use to the building twenty-four
         (24) hours per day, 365 days per year; however, Landlord will not be
         required to provide snow removal or building maintenance during such
         after-hours use unless agreed in advance that Tenant shall pay the cost
         thereof.

(V)      TENANT'S OPTION TO TERMINATE: Provided that Tenant is not in default in
         payment of any of its obligations under this Lease, Tenant shall have
         the option to terminate effective at the end of the third (3rd) Lease
         Year. If Tenant elects to terminate, Tenant must exercise its option by
         giving written notice to Landlord not less than one hundred twenty
         (120) days prior to the end of the third Lease Year and by paying to
         Landlord on or before the effective termination date the unamortized
         amount of the Landlord Contribution set forth in Section 1.01 (P)
         assuming that said Landlord Contribution is amortized over a 60 (sixty)
         month lease term together with interest at ten percent (10%) per annum.
         Accordingly, if the Landlord Contribution is $107,590, then the
         unamortized portion at the end of the third Lease Year shall be
         $49,538.91.

         SECTION 1.02. SIGNIFICANCE OF A BASIC LEASE PROVISION. The foregoing
provisions of Section 1.01 summarize for convenience only certain fundamental
terms of the Lease delineated more fully in the Articles and Sections referenced
therein. In the event of a conflict between the provisions of Section 1.01 and
the balance of the Lease, the latter shall control.

         SECTION 1.03. ENUMERATION OF EXHIBITS. The exhibits enumerated in this
Section and attached to this Lease are incorporated in the Lease by this
reference and are to be construed as a part of the Lease.

                         ARTICLE II. GRANT AND PREMISES

         SECTION 2.01. PREMISES. In consideration for the rent to be paid and
covenants to be performed by Tenant, Landlord hereby leases to Tenant, and
Tenant leases from Landlord for the Term and upon the terms and conditions
herein set forth premises described in Section 1.01(I) (hereinafter referred to
as the "Premises"), located in an office building development referred to in
Section 1.01(H) (hereinafter referred to as the "Building"). The legal
description of the Building is attached hereto as Exhibit "B". Gross rentable
area measurements herein specified are from the exterior of the perimeter walls
of the building to the center of the interior walls. In addition, the factor set
forth in Section 1.01(I) has been added to the area as measured above to adjust
for Tenant's proportionate share of common hallways, restrooms, etc. in the
building.

         The exterior walls and roof of the Premises and the areas beneath said
Premises are not demised hereunder and the use thereof together with the right
to install, maintain, use, repair, and replace pipes, ducts, conduits, and wires
leading through the Premises in locations which will not materially interfere
with Tenant's use thereof and serving other parts of the building or buildings
are hereby reserved to Landlord. Landlord reserves (a) such access rights
through the Premises as may be reasonably necessary to enable access by Landlord
to the balance of the building and reserved areas and elements as set forth
above; and (b) the right to install or maintain meters on the Premises to
monitor use of utilities. In exercising such rights, Landlord will use
reasonable efforts so as to not commit waste upon the Premises and as far as
practicable to minimize annoyance, interference or damage to Tenant when making
modifications, additions or repairs.

         Subject to the provisions of Article VIII contained hereinbelow, Tenant
and its customers, agents and invitees have the right to the non-exclusive use,
in common with others of such unreserved automobile parking spaces, driveways,
footways, and other facilities designated for common use within the Building. To
the extent any spaces are designated for "customer parking" Tenant agrees to
cause its employees not to park in said "customer parking" stalls.

         Said Premises are subject to restrictive covenants and conditions
governing the Utah Valley Business Park which are recorded in the office of the
Utah County Recorder which are attached as Exhibit "F". Landlord represents that
Landlord is not aware of any conflict between the aforesaid restrictive
covenants and conditions and the provisions of this lease.

                                ARTICLE III RENT

<PAGE>

         SECTION 3.01. BASE MONTHLY RENT. Tenant agrees to pay to Landlord the
Base Monthly Rent set forth in Section 1.01(L) at such place as Landlord may
designate, without prior demand therefor, without offset or deduction and in
advance on or before the first day of each calendar month during the Rental
Term, commencing on the Rental Commencement Date. In the event the Rental
Commencement Date occurs on a day other than the first day of a calendar month,
then the Base Monthly Rent to be paid on the Rental Commencement Date shall
include both the Base Monthly Rent for the first full calendar month occurring
after the Rental Commencement Date, plus the Base Monthly Rent for the initial
fractional calendar month prorated on a per-diem basis (based upon a thirty (30)
day month).

         SECTION 3.02. ADJUSTMENTS. Tenant's Base Monthly Rent shall be
increased on the Adjustment Dates set forth in Section 1.01(M).

         SECTION 3.03.  TENANT'S SHARE OF OPERATING EXPENSES.

                  (a) Tenant shall pay Tenant's pro-rated share of Budgeted
         Operating Expenses for exterior utilities, common area maintenance,
         insurance, property taxes and assessments, repairs, security, and
         building management fees and costs as set forth in Section 1.01(N) and
         Exhibit "F". Tenant's pro-rated share of Landlord's expenses is set
         forth in Section 1.01(O) and is calculated by dividing the gross
         rentable area of the Premises by 95% of the gross rentable area of the
         Premises.

                  (b) Except as set forth in Section 3.03 (c), Landlord shall
         bill Tenant for Tenant's Share, if any, at the end of the second Lease
         Year of the Rental Term. Beginning with the third Lease Year,
         one-twelfth (1/12th) of Tenant's Share for the prior year shall be
         added to the Base Monthly Rent as determined in Sections 3.01 and 3.02
         for the next full twelve (12) calendar months of the Rental Term and
         shall be paid as set forth in Section 3.05.

                  Within sixty (60) days after the end of each Lease Year,
         Landlord shall deliver to Tenant an accounting in reasonable detail of
         actual Operating Expenses certified by an officer of Landlord as true
         and correct together with a calculation of Tenant's share of such
         expenses incurred by Landlord in that Lease Year. Should the actual
         aggregate amount of such Operating Expense exceed the Budgeted amount
         paid by Tenant during that Lease Year, then Tenant shall pay the amount
         of any excess within twenty (20) days after receipt of invoice. However
         if the payments by Tenant for Budgeted Operating Expenses for the
         previous year exceeded the actual aggregate amount incurred by
         Landlord, then Tenant may deduct the excess amount from the next
         monthly payment of Base Monthly Rent due from Tenant.

                  (c) Notwithstanding anything to the contrary herein,
         electrical and gas utility expenses relating directly to the interior

                  a) Landlord shall be responsible for removal of any Hazardous
         Substances that existed at the Leased Premises prior to construction or
         any that Landlord has or does install at the Leased Premises or
         Building. After reasonable inquiry, Landlord is not aware of any
         existing Hazardous Substances in the Building or Common Areas.

                  b) Tenant shall not use, produce, store, release, dispose or
         handle in or about the Leased Premises or transfer to or from the
         Leased Premises (or permit any other party to do such acts) any
         Hazardous Substance except in compliance with all applicable
         Environmental Laws. Tenant shall not construct or use any improvements,
         fixtures or equipment or engage in any act on or about the Leased
         Premises that would require the procurement of any license or permit
         pursuant to any Environmental Law and Tenant shall remove any Hazardous
         Substance resulting from Tenant's or its agent's contractors, or
         business invitee's acts. Tenant shall immediately notify Landlord of
         (i) the existence of any Hazardous Substance on or about the Leased
         Premises that may in violation of any Environmental Law (regardless of
         whether Tenant is responsible for the existence of such Hazardous
         Substance), (ii) any proceeding or investigation by any governmental
         authority regarding the presence of any Hazardous Substance on the
         Leased Premises or the migration thereof to or from any other property,
         (iii) all claims made or threatened by any third party against Tenant
         relating to any loss or injury resulting from any Hazardous Substance
         in or about the Leased Premises. "Environmental Laws" shall mean any
         federal, state or local statute, ordinance, rule, regulation or
         guideline pertaining to health, industrial hygiene, or the environment,
         including without limitation, the federal Comprehensive Environmental
         Response, Compensation, and Liability Act; "Hazardous Substance" shall
         mean all substances, materials and wastes that are or become regulated,
         or classified as hazardous or toxic, under any Environmental Law. If it
         is determined that any Hazardous Substance exists on the Premises
         resulting from any act of Tenant or its employees, agents, contractors,
         licensees, subtenants or customers, then Tenant shall immediately take
         necessary action to cause the removal of said substance and shall
         remove such within ten (10) days after discovery. Notwithstanding the
         above, if the Hazardous Substance is of a nature that can not be
         reasonably removed within ten (10) days Tenant shall not be in default
         if Tenant has commenced to cause such removal and proceeds diligently
         thereafter to complete removal, except that in all cases, any Hazardous
         Substance must be removed as soon as possible. Furthermore,
         notwithstanding the above, if in the good faith judgment of Landlord,
         the existence of such Hazardous Substance creates an emergency or is of
         a nature which may result in immediate physical danger to persons at
         the Property, and Tenant fails to immediately remove the same after
         written notice from Landlord, Landlord may enter upon the Premises and
         remove such Hazardous Substances and charge the reasonable cost thereof
         to Tenant as Additional Rent.

                  c) The party herein responsible for removal of Hazardous
         Substances shall upon learning of such condition proceed within five
         (5) days thereafter to commence removal of such Hazardous Substance and
         shall diligently continue to effect such removal until completion.
         Removal shall be accomplished in accordance with any applicable safety
         standards.

non-customer parking; and to do and perform such other acts in and to said areas

such revocations or diminutions are deemed by Landlord to serve the best
interests of the Building.

         Lease. Tenant agrees to pay as additional rent the total amount of any
         increase in the insurance premium of Landlord over that in effect prior

release and discharge the other party hereto and any officer, agent, employee or
representative of such party, of and from any liability whatsoever hereafter
arising from loss, damage or injury caused by fire or other casualty for which

subrogation) is carried by the injured party at the time of such loss, damage or
injury to the extent of any recovery by the injured party under such insurance.

                    ARTICLE XVII DESTRUCTION OF THE PREMISES

         SECTION 17.01.  DESTRUCTION.

<PAGE>

                  (a) If the Premises are partially or totally destroyed by fire
         or other casualty insurable under standard fire insurance policies with
         extended coverage endorsement so as to become partially or totally
         untenantable, the same shall be repaired or rebuilt as speedily as
         practical under the circumstances at the expense of the Landlord,
         unless Landlord elects not to repair or rebuild as provided in
         Subsection (b) of this Section 17.01. During the period required for
         restoration, a just and proportionate part of Base Rent, additional
         rent and other charges payable by Tenant hereunder shall be abated
         until the Premises are repaired or rebuilt.

                  (b) If the Premises are (I) rendered totally untenantable by
         reason of an occurrence described in Subsection (a), or (II) damaged or
         destroyed as a result of a risk which is not insured under Landlord's
         fire insurance policies, or (III) at least twenty percent (20%) damaged
         or destroyed during the last year of the Rental Term, or (IV) if the
         Building is damaged in whole or in part (whether or not the Premises
         are damaged), to such an extent that Tenant cannot practically use the
         Premises for its intended purpose, then and in any such events Landlord
         or Tenant may at its option terminate this Lease Agreement by notice in
         writing to the other party within sixty (60) days after the date of
         such occurrence. Unless Landlord or Tenant gives such notice, this
         Lease Agreement will remain in full force and effect and Landlord shall
         repair such damage at its expense as expeditiously as possible under
         the circumstances.

                  (c) If Landlord should elect or be obligated pursuant to
         Subsection (a) above to repair or rebuild because of any damage or
         destruction, Landlord's obligation shall be limited to the original
         Building any other work or improvements which may have been originally
         performed or installed at Landlord's expense. If the cost of performing
         Landlord's obligation exceeds the actual proceeds of insurance paid or
         payable to Landlord on account of such casualty by $20,000, Landlord
         may terminate this Lease Agreement unless Tenant, within fifteen (15)
         days after demand therefor, deposits with Landlord a sum of money
         sufficient to pay the difference between the cost of repair and the
         proceeds of the insurance available for such purpose. Tenant shall
         replace all work and improvements not originally installed or performed
         by Landlord at its expense.

                  (d) Except as stated in this Article XVII and as otherwise
         provided in this Lease, Landlord shall not be liable for any loss or
         damage sustained by Tenant by reason of casualties mentioned
         hereinabove or any other accidental casualty.

                           ARTICLE XVIII CONDEMNATION

         SECTION 18.01. CONDEMNATION. As used in this Section the term
"Condemnation Proceeding" means any action or proceeding in which any interest
in the Premises or Building is taken for any public or quasi-public purpose by
any lawful authority through exercise of the power of eminent domain or right of
condemnation or by purchase or otherwise in lieu thereof. If the whole of the
Premises is taken through Condemnation Proceedings, this Lease shall
automatically terminate as of the date possession is taken by he condemning
authority. If in excess of twenty-five (25%) percent of the Premises is taken,
either party hereto shall have the option to terminate this Lease by giving the
other written notice of such election at any time within thirty (30) days after
the date of taking. If less than twenty-five (25%) percent of the space is taken
and Landlord determines, in Landlord's sole discretion, that a reasonable amount
of reconstruction thereof will not result in the Premises or the Building
becoming a practical improvement reasonably suitable for use for the purpose for
which it is designed, then Landlord may elect to terminate this Lease Agreement
by giving thirty (30) days written notice as provided hereinabove. In all other
cases, or if neither party exercises its option to terminate, this Lease shall
remain in effect and the rent payable hereunder from and after the date of
taking shall be proportionately reduced in proportion to the ratio of: (1) the
area contained in the Premises which is capable of occupancy after the taking;
to (II) the total area contained in the Premises which was capable of occupancy
prior to the taking. In the event of any termination or rental reduction
provided for in this Section, there shall be a proration of the rent payable
under this Lease and Landlord shall refund any

<PAGE>

excess theretofore paid by Tenant. Whether or not this Lease is terminated as
a consequence of Condemnation Proceedings, all damages or compensation
awarded for a partial or total taking, including any sums compensating Tenant
for diminution in the value of or deprivation of its leasehold estate, shall
be the sole and exclusive property of Landlord, except that Tenant will be
entitled to any awards intended to compensate Tenant for expenses of locating
and moving Tenant's operations to a new space.

                          ARTICLE XIX DEFAULT OF TENANT

         SECTION 19.01. DEFAULT - RIGHT TO RE-ENTER. In the event of any failure
of Tenant to pay any rental due hereunder within ten (10) days after written
notice that the same is past due shall have been received by Tenant, or any
failure by Tenant to perform any other of the terms, conditions or covenants
required of Tenant by this Lease within thirty (30) days after written notice of
such default shall have been received by Tenant, (unless such default is of the
type which can not reasonably be cured within thirty (30) days in which case
Tenant shall not be in default if Tenant commences to cure and then proceeds
diligently to cure said default until cured), or if Tenant permits this Lease to
be taken under any writ of execution, then Landlord, besides other rights or
remedies it may have, shall have the right to declare this Lease terminated and
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, without
evidence of notice or resort to legal process and without being deemed guilty of
trespass, or becoming liable for any loss or damage which may be occasioned
thereby. Tenant hereby waives all compensation for the forfeiture of the term or
its loss of possession of the Premises in the event of the forfeiture of this
Lease as provided for above.

         SECTION 19.02. DEFAULT - RIGHT TO RE-LET. Should Landlord elect to
re-enter, as herein provided, or should it take possession pursuant to legal
proceedings or pursuant to any notice provided for by law, it may either
terminate this Lease or it may from time to time, without terminating this
Lease, make such alterations and repairs as may be necessary in order to relet
the Premises, and may 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
its sole discretion may deem advisable. Upon each such reletting, all rentals
received by Landlord from such reletting shall be applied first to the payment
of any costs and expenses of such reletting, including brokerage fees and
attorney's fees and costs of such alterations and repairs; second, to the
payment of rent or other unpaid obligations due hereunder; and the residue, if
any, shall be held by Landlord and applied in payment of future rent as the same
may become due and payable hereunder. If such rental received from such
reletting during any month be less than that to be paid during that month by
Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such
deficiency shall be calculated and paid monthly. No such re-entry or taking
possession of said Premises by Landlord shall be construed as an election on its
part to terminate this Lease unless a written notice of such intention be given
to Tenant or unless the termination thereof be decreed by a court or competent
jurisdiction. Notwithstanding any such reletting without termination, Landlord
may at any time elect to terminate this Lease for such previous default. Should
Landlord at any time terminate this Lease for any default, in addition to any
other remedies it may have, it may recover from Tenant all damages it may incur
by reason of such default, including the cost of recovering the Premises,
reasonable attorney's fees, and including the excess, if any, of the amount of
rent and charges equivalent to rent reserved in this Lease for the remainder of
the stated term over the actual amount received by Landlord for such period.
Landlord shall, in a commercially reasonable manner, mitigate its damages as a
result of Tenant's default.

         SECTION 19.03. LEGAL EXPENSES. In case of default by either party in
the performance and obligations under this Lease, the defaulting party shall pay
all costs incurred in enforcing this Lease, or any right arising out of such
default, whether by suit or otherwise, including a reasonable attorney's fee.

         substantially all of the assets of the Tenant.

         benefit of creditors.

                  (c) Any action taken or suffered by or against the Tenant
         under any federal or state insolvency or bankruptcy act, unless (if
         involuntary) dismissed within sixty (60) days.

                  (d) The appointment of a guardian, conservator, trustee, or
         other similar officer to take charge of all or any substantial part of
         the Tenant's property, unless (if involuntary) dismissed within sixty
         (60) days.

         Neither this Lease, nor any interest therein nor any estate thereby
created shall pass to any trustee, guardian, receiver or assignee for the
benefit of creditors or otherwise by operation of law.

                           ARTICLE XXI LANDLORD ACCESS

         SECTION 21.01. LANDLORD ACCESS. Landlord or Landlord's agent shall have
the right to enter the Premises at all reasonable times to examine the same, or
to show them to prospective purchasers or lessees of the Building, or to make
all repairs, alterations, improvements or additions as Landlord may deem
necessary or desirable, and Landlord shall be allowed to take all material into
and upon said Premises that may be required therefor without the same
constituting an eviction of Tenant in whole or in part, and provided that
Landlord promptly completes such repairs in a commercially reasonable manner as
soon as reasonably possible, rent shall not abate while said repairs,
alterations, improvements, or additions are being made, by reason of loss or
interruption of business of Tenant, or otherwise which shall not materially
affect Tenant. During the ninety days prior to the expiration of the Rental Term
of this Lease or any renewal term, Landlord may exhibit the Premises to
prospective tenants and place upon the Premises the usual notices "To Let" or
"For Rent" which notices Tenant shall permit to remain thereon without
molestation. Notwithstanding the above, Tenant shall have the right to designate
a representative to accompany Landlord during any time Landlord may enter upon
the Premises.

                          ARTICLE XXII LANDLORD'S LIEN

         SECTION 22.01. LANDLORD'S LIEN. Landlord agrees to subordinate its
statutory Landlord's lien, if any, to the interest of any lender who is
financing or securing equipment, trade fixtures, or furnishings of Tenant to be
used at the Leased Premises provided that Lender, Tenant, and Landlord execute a
mutually acceptable form providing for notice to Landlord prior to removal of

         SECTION 26.01. SECURITY DEPOSIT. The Landlord herewith acknowledges
receipt of the amount set forth in Section 1.01(R), which it is to retain as
security for the faithful performance of all the covenants, conditions and
agreements of this Lease, but in no event shall the Landlord be obliged to apply
the same upon rents or other charges in arrears or upon damages for Tenant's
failure to perform the said covenants, conditions and agreements. The Landlord
may so apply the security, at its option, and the Landlord's right to possession
of the Premises for non-payment of rent or for any other reason shall not in any
event be affected by reason of the fact that the Landlord holds this security.
The said sum, if not applied toward the payment of rent in arrears or toward the
payment of damages suffered by the Landlord by reason of the Tenant's breach of
the covenants, conditions and agreements of this Lease, is to be returned to the

Tenant's default or because of the Tenant's failure to carry out the covenants,

security toward damages as may be suffered or shall accrue thereafter by reason
of the Tenant's default or breach. The Landlord shall not be obligated to keep
the said security as a separate fund, but may mix the said security with its own
funds.

any covenant or provision of this Lease shall discharge or invalidate such
covenant or provision or affect the right of Landlord to enforce the same in the
event of any subsequent breach. One or more waivers of any covenant or condition
by Landlord shall not be construed as a waiver of a subsequent breach of the
same covenant or condition and the consent to or approval of any subsequent
similar act by Tenant. No breach of a covenant or condition of this Lease shall
be deemed to have been waived by Landlord, unless such waiver be in writing
signed by Landlord.

and Landlord may accept such check or payment without prejudice to Landlord's
right to recover the balance of such rent or receivable or pursue any other
remedy available under this Lease or the law of the state where the Premises are
located.

         SECTION 27.06. NO OPTION. The submission of this Lease for examination

         SECTION 27.13.  LANDLORD INDEMNITY RE: FLOOR SETTLING.

                  (a) Landlord will correct the existing condition and take all
         prudent measures to ensure that there should be no further settling of
         the floor.

                  (b) To the extent that Tenant is deprived of the use of any
         portion of the Premises as a result of said floor settling, the rental
         shall be abated proportionate to the area of deprivation for the time
         Tenant is so deprived of such use.

                  (c) If it appears that Tenant may be deprived of the use of
         any portion of said Premises in the future for any extended period of
         time, Landlord shall use good faith efforts to provide comparable
         temporary space in the Utah Valley Business Park and shall pay the
         actual moving costs incurred in relocation and any difference in
         occupancy expense charged to Tenant for the temporary space.

                  (d) Furthermore, if Tenant determines that the settling
         problem has not been cured and that Tenant can not, in good faith,
         reasonably and practically operate in said Premises, then Tenant may
         terminate the said Lease upon written notice to Landlord without
         further opportunity to cure by Landlord, and Landlord shall indemnify
         Tenant to the extent that Landlord shall pay reasonable actual moving
         costs incurred by Tenant to relocate and any increased rental and
         occupancy costs incurred by Tenant for the unexpired term of said Lease
         as a result of relocation.

         SECTION 27.14. INSPECTION OF RECORDS. Tenant may upon ten (10) days
written notice to Landlord elect to inspect and review, at Landlord's place of
business, Landlord's records pertaining to Operating Expenses referred to in
this Section 3.03 and Section 1.01 (N) as well as electrical and gas

utility charges referred to in Section 3.03 (c) and Section 12.02. If upon
review and audit, it is determined that Tenant has been overcharged or
undercharged for Tenant's share of any of the above mentioned expenses, then
Landlord or Tenant shall pay to the other the amount of any excess charge or
deficiency within ten (10) days after the determination that such error has
occurred.

         IN WITNESS WHEREOF, Landlord and Tenant have executed and delivered
this Lease as of the day and year first above written.
