        Said area is calculated by multiplying the full second floor usable area
        of 5,019 s.f. by 1.2007 to account for Tenant's proportionate share of
        common area corridors, lobby, mechanical, electrical, and other service
        rooms etc. in the Building.

(J)     DELIVERY OF POSSESSION (SECTION 5.03): On or before February 15, 1999,

        said increase, Landlord shall use a fraction the denominator of which
        shall be said index for the month of November, 1998 and the numerator of
        which shall be the index for the November immediately previous the
        Escalation Date. If there is a decrease in the relevant Consumer Price
        Index, the Base Monthly Rent shall not be adjusted. If the U.S.
        Department of Labor ceases to publish said Consumer Price Index, the

        excess of those specified above, Tenant shall pay an extra hourly
        utility charge of $0.20 per hour per 1,000 usable square feet for
        lighting and electricity and $3.00 per hour per 1,000 usable square feet
        for mechanical/HVAC system for each full or partial hour during which
        Tenant operates.

(T)     ADJUSTMENTS BASED ON FINAL AREA DETERMINATION: Upon final completion,
        the Building shall be measured and the actual rentable area of the
        Premises determined in accordance with standards of Section 2.01. The
        sums set forth in Sections 1.01 (L), (M), (O), (Q) and (U) shall then be

        shall be made not less than five (5) days prior to the Termination Date.
        To calculate the "unamortized portion", Landlord shall multiply the
        amount of Landlord Contribution set forth in Section 1.01 (Q) as
        adjusted pursuant to Section 1.01 (T) by a fraction, the numerator of
        which shall be the number of months between the Termination Date as
        provided in this Section 1.01 (X) and January 31, 2004 and the
        denominator of which shall be 60.

        SECTION 1.03 ENUMERATION OF EXHIBITS. The exhibits enumerated in this

                  EXHIBIT "D" - TENANT'S WORK

                         ARTICLE II. GRANT AND PREMISES

(hereinafter the "Building") suitable for use as office research and development
space, together with related parking facilities and other improvements necessary
to enable to the Building to be so used (the Building and related facilities and
improvements are hereinafter collectively referred to as the "Improvements").

        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" or "Leased
Premises"), located in the Building. 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
(1) has been added to the area as measured above to adjust for Tenant's
proportionate share of common hallways, restrooms, elevators, stairways, 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
subject to reasonable notice to Tenant 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, 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, except that with
respect to non-exclusive automobile parking spaces, Tenant shall cause its
employees to park their cars only in areas specifically designated from time to
time by Landlord for that purpose. Landlord shall have the right to designate,
in its sole business judgment, certain spaces as "customer" parking spaces and
Tenant shall use its best efforts to cause its employees not to park in said
customer parking.

shall not include depreciation on the Building and Improvements; amounts paid
toward principal or interest of loans of Landlord; nor "Direct Costs" as defined
in Section 3.03 (b). If the cost of any repair or replacement exceeds $5,000.00
and is of the nature normally defined as a "capital cost" under generally
accepted accounting principles, then such cost shall be amortized together with
interest at 10% per annum and charged as a "Basic Cost" over the useful life of
said repair or replacement. Tenant shall pay its Proportionate Share of Basic
Costs. "Tenant's Proportionate Share of Basic Costs" shall mean the percentage
derived from a fraction, the numerator of which is the gross rentable area of
the Premises as set forth in Section 1.01(I) and the denominator of which is
the gross rentable square footage of the Building (89,741 s.f.). Tenant's
Proportionate Share of Basic Costs initially is set forth in Section 1.01(O),
subject to increase or decrease due to increases or decreases in the gross
rentable square footage of the Premises and/or the Building.

        (b) "Direct Costs" shall mean all actual costs and expenses incurred by
Landlord in connection with the operation, management, maintenance, replacement,
and repair of the Premises, including but not limited to janitorial services,
maintenance, repairs, supplies, utilities, heating, ventilation, air
conditioning, and property management fees, (which property management fees
shall not exceed four (4%) percent of the Base Monthly Rent set forth herein).
If any category of Direct Costs can only be determined on a Building wide basis,
Tenant's proportionate share of any such category of Direct Costs will be based
on the same percentage established for Tenant's Proportionate Share of Basic
Costs.

        (c) Landlord may cause at Landlord's sole cost and expense (which shall
not be reimbursable in whole or in part by Tenant) meters or monitors to be
installed to measure actual electrical and ventilation/air conditioning usage in
the Premises by Tenant. "Metered Costs" shall mean the actual cost of such
usage. If such meters are installed, Tenant shall pay Landlord monthly, as
Additional Rent, the estimated costs of such metered electrical and
ventilation/air conditioning usage. If the costs of ventilation/air conditioning
usage are not separately metered for tenants in the Building said costs shall be
considered Direct Costs and shall be calculated as set forth in 3.03(a).


        (d) "Estimated Costs" shall mean the projected amount of Direct Costs,
Metered Costs and Proportionate Share of Basic Costs. The Estimated Costs for
the calendar year in which the Lease commences are set forth in Section 1.01(O),
and are not included in the Base Monthly Rent. If the Estimated Costs as of the
date Tenant takes occupancy are greater than the Estimated Costs at the time
this Lease is executed, the Estimated Costs shall be increased to equal the
Estimated Costs as of the date of Tenant's occupancy.

SECTION 3.04 REPORT OF COSTS AND STATEMENT OF ESTIMATED COSTS.

        (a) Within sixty (60) days after the expiration of each calendar year
occurring during the term of this Lease, Landlord shall furnish Tenant a written
statement ("Annual Report of Costs") of the Tenant's actual Direct Costs,
Metered Costs and Proportionate Share of Basic Costs occurring during the
previous calendar year. Such Annual Report of Costs shall show in reasonable
detail a breakdown of the components of the Costs set forth herein. The Annual
Report of Costs shall specify the amount by which said actual costs for the
previous year exceeds or is less than the amounts paid by Tenant as Estimated
Costs during the previous calendar year.

<PAGE>   8

                (b) At the same time specified in Section 3.04 (a), Landlord
        shall furnish Tenant a written statement of the Estimated Costs for the
        then current calendar year ("Annual Statement of Estimated Costs.")

                (c) Landlord's records of costs shall be open to inspection by
        Tenant at Landlord's office during business hours and upon five (5) days
        prior written notice to Landlord of Tenant's desire to conduct such
        inspection. If Tenant discovers any errors in Landlord's calculations as
        a result of such inspections, Landlord shall immediately adjust such
        costs and credit or charge Tenant for its share of the discrepancy.

        SECTION 3.05 PAYMENT OF ADDITIONAL RENT. Tenant shall pay additional
rent ("Additional Rent") as follows:

                (a) With each monthly payment of Base Monthly Rent pursuant to
        Section 3.01 above, Tenant shall pay TO Landlord, without offset or
        deduction, one-twelfth (1/12th) of the Annual Statement of Estimated
        Costs. If at any time Landlord obtains information that indicates that
        any of the categories of cost comprising Estimated Costs are
        significantly different than as calculated in the Annual Statement of
        Estimated Costs then in effect, Landlord may amend said Statement in
        order to reflect a more accurate prediction of the actual costs that
        will be incurred during the calendar year, and Tenant will pay amended
        Additional Rent consistent with said amended Statement.

                (b) Within thirty (30) days after delivery of the Annual Report
        of Costs, Tenant shall pay to Landlord the amount by which Direct Costs,
        Metered Costs and Proportionate Share of Basic Costs, as specified in
        the Report, exceed the aggregate of Estimated Costs actually paid by
        Tenant as Additional Rent for the year at issue.

                (c) If the Annual Report of Costs indicates that the Estimated
        Costs paid by Tenant exceeded the actual Direct Costs, Metered Costs and
        Proportionate Share of Basic Costs for the same year, Landlord, at its
        sole election, shall either (i) pay the amount of such excess to Tenant,
        or (ii) apply such excess against the next installments) of Base Monthly
        Rent and/or Additional Rent due hereunder and so notify Tenant.

        SECTION 3.06 TAXES.

                (a) Landlord shall pay all real property taxes and assessments

        reimbursed by Tenant as a part of Basic Costs.

                (b) Tenant shall prior to delinquency pay all taxes,
        assessments, charges, and fees which during the Rental Term hereof may
        be imposed, assessed, or levied by any governmental or public authority
        against or upon Tenant's use of the Premises or any inventory, personal
        property, fixtures or equipment kept or installed, or permitted to be
        located therein by Tenant.

        SECTION 3.07 PAYMENTS. All payments of Base Monthly Rent, Additional
Rent and other payments to be made to Landlord shall be made on a timely basis
and shall be payable to Landlord or as Landlord may otherwise designate. All
such payments shall be mailed or delivered to Landlord's principal office set
forth in Section 1.01 (C), or at such other place as Landlord may designate from
time to time in writing. If mailed, all payments shall be mailed in sufficient
time and with adequate postage thereon to be received in Landlord's account by
no later than the due date for such payment. If Tenant shall fail to pay any
Base Monthly Rent or any Additional Rent or any other amounts or charges within
five (5) days after the due date, Tenant shall pay interest from the due date of
such past due amounts to the date of payment, both before and after judgment at
a rate equal to the greater of fourteen (14%) percent per annum or two (2%)
percent over the "prime" or "base" rate charged by Zions First National Bank of
Utah at the due date of such payment; provided however, that in any case the
maximum amount or rate of interest to be charged shall not exceed the maximum
non-usurious rate in accordance with applicable law. Notwithstanding the above,
Landlord shall waive said interest for one late payment in any calendar year
provided that Tenant pays the past due charge within five (5) days after notice
from Landlord that the charge is past due.

        Environmental Law. Upon Tenant obtaining actual knowledge of same,
        Tenant shall immediately notify Landlord of (i) the existence of any
        Hazardous Substance on or about the Leased Premises that may be 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

        commenced to cause such removal and proceeds diligently thereafter to
        complete removal, except that in all cases, any Hazardous Substance must
        be removed within sixty (60) days after discovery thereof. 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, Landlord may enter upon the Leased Premises and remove such
        Hazardous Substances and, if the existence was a result of the act of
        the Tenant or its employee, agent, contractor, licensee, subtenant, or
        customers, Landlord may charge the cost thereof to Tenant as Additional

                (b) Upon termination of this Lease at any time and for any
        reason whatsoever, Tenant shall surrender and deliver up the Premises to
        Landlord in the same condition as when the Premises were delivered to
        Tenant or as altered as provided in Section 9.01, ordinary wear and tear
        excepted. Upon request of Landlord, Tenant shall promptly remove all
        personal property from the Premises and repair any damage caused by such
        removal. Obligations under this Lease relating to events occurring or
        circumstances existing prior to the date of termination shall survive
        the expiration or other termination of the Rental Term of this Lease.


                      ARTICLE XI. INSURANCE AND INDEMNITY

        SECTION 11.01 LIABILITY INSURANCE AND INDEMNITY. Tenant shall, during
all terms hereof, keep in full force and effect a policy of public bodily injury
and property damage liability insurance with respect to the Premises, with a
combined single limit of not less than Two Million Dollars ($2,000,000.00) per
occurrence. The policy shall name Landlord, Property Manager (i.e., Woodbury
Corporation) and any other persons, firms or corporations designated by Landlord
and Tenant as insured, and shall contain a clause that the insurer will not
cancel or change the insurance without first giving the Landlord ten (10) days
prior written notice. Such insurance shall include an endorsement permitting
Landlord and Property Manager to recover damage suffered due to act or omission
of Tenant, notwithstanding being named as an additional "Insured party" in such
policies. Such insurance may be furnished by Tenant under any blanket policy
carried by it or under a separate policy therefor. The insurance shall be with
an insurance company approved by Landlord and a copy of the paid-up policy
evidencing such insurance or a certificate of insurer



                                       9
<PAGE>   13

certifying to the issuance of such policy shall be delivered to Landlord. If
Tenant fails to provide such insurance, Landlord may do so and charge same to
Tenant.

        Tenant will indemnify, defend and hold Landlord harmless from and
against any and all claims, connection with loss of life, personal injury and/or
damage to actions, damages, liability and expense in property arising from or
out of any occurrence in, upon or at the Premises or from the occupancy or use
by Tenant of the Premises or any part thereof, or occasioned by any act or
omission of Tenant, its agents, contractors, employees, servants, sublessees,
concessionaires or business invitees unless caused by the negligence of Landlord
its employees, contractors or agents, and to the extent not covered by its fire,
casualty and liability insurance. In case Landlord shall, without fault of its
part, be made a party to any litigation commenced by or against Tenant, then
Tenant shall protect and hold Landlord harmless and shall pay ALL costs,
expenses and reasonable attorney fees incurred or paid by either in defending
itself or enforcing the covenants and agreements of this Lease.

        SECTION 11.02 FIRE AND CASUALTY INSURANCE.

                (a) Subject to the provisions of this Section 11.02, Landlord
        shall secure, pay for, and at all times during the terms hereof
        maintain, insurance providing coverage upon the building improvements in
        an amount equal to the full insurable value thereof (as determined by
        Landlord) and insuring against the perils of fire, extended coverage,
        vandalism, and malicious mischief. All insurance required hereunder
        shall be written by reputable, responsible companies licensed in the
        State of Utah. Tenant shall have the right, at its request at any
        reasonable time, to be furnished with copies of the insurance policies
        then in force pursuant to this Section, together with evidence that the
        premiums therefor have been paid.

                (b) Tenant agrees to maintain at its own expense such fire and
        casualty insurance coverage as Tenant may desire or require in respect
        to Tenant's personal property, equipment, furniture, fixtures or
        inventory and Landlord shall have no obligation in respect to such
        insurance or losses. All property kept or stored on the Premises by
        Tenant or with Tenant's permission shall be so done at Tenant's sole
        risk and Tenant shall indemnify Landlord against and hold it harmless
        from any claims arising out of loss or damage to same.

                (c) Landlord represents that the Premises will be initially
        designed to permit the operation of Tenant's computer-related business
        as described to Landlord as of the date of this Lease without any
        increase in casualty insurance premium. Thereafter, Tenant will not
        permit said Premises to be used for any purpose which would render the
        insurance thereon void or cause cancellation thereof or increase the
        insurance risk or increase the insurance premiums (unless Tenant agrees
        to pay such increased premiums) in effect just prior to the commencement
        of this 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 to the commencement of this lease resulting from Tenant use of the
        Premises. If Tenant installs any electrical or other equipment which
        overloads the lines in the Premises, Tenant shall at its own expense
        make whatever changes are necessary to comply with the requirements of
        Landlord's insurance.

                (d) Tenant shall be responsible for all glass breakage within
        the Premises and any exterior glass breakage resulting from acts or
        negligence of Tenant, its employees, agents, contractors, licensees,
        subtenants, or customers and agrees to immediately replace all glass
        broken or damaged, for which Tenant is responsible, with glass of the
        same quality as that broken or damaged. Landlord may replace, at
        Tenant's expense, any such broken or damaged glass if not replaced by
        Tenant within five (5) days after such damage and charge the cost
        thereof to Tenant. Landlord shall be responsible for replacement of any
        other damaged glass at the Premises or the Building and shall similarly
        replace such in the same manner required of Tenant hereunder.

        SECTION 11.03 WAIVER OF SUBROGATION. Each party hereto does hereby
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
insurance (permitting waiver of liability and containing a waiver of
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 XII. UTILITY CHARGES

        SECTION 12.01 OBLIGATION OF LANDLORD. Subject to the terms of Section

        (a)     Electricity, water, gas and sewer service.

        (b)     Telephone connection, but not including telephone stations and
                equipment (it being expressly under-stood and agreed that Tenant
                shall be responsible for the ordering and installation of
                telephone lines and equipment which pertain to the Premises).

        (c)     Heat and air-conditioning to such extent and to such levels as,
                in Landlord's judgment, is reasonably required for the
                comfortable use and occupancy of the Premises subject however to
                any limitations imposed by University Research Park or any
                government agency. The parties agree and understand that the
                above heat and air-conditioning will be provided Monday through
                Friday from 7:00 a.m. to 6:00 p.m. and Saturday from 8:00 a.m.

charges, electric light bulbs (but not fluorescent bulbs used in fixtures
originally installed in the Premises) and ALL other materials and services not
expressly required to be provided and paid for pursuant to the provisions of
Section 12.01 above. Tenant covenants to use good faith efforts to reasonably
conserve utilities by turning off lights and equipment when not in use and
taking such other reasonable actions in accordance with sound standards for
energy conservation. Landlord reserves the right at Landlord's sole expense
(without reimbursement for such installation and meter costs from Tenant) to
separately meter or otherwise monitor any utility usage and to separately charge
Tenants for its own utilities, in which case an equitable adjustment shall be
made to Base Rental and Tenant's share of Operating Expenses as set forth in
this Lease. Additional limitations of Tenant are as follows:

                (a) Tenant will not, without the written consent of Landlord,
        which consent shall not be unreasonably withheld, use any machine or
        device at the Premises using current in excess of 208 volts which will
        in any way or to any extent increase the amount of electricity or water
        usually furnished or supplied for use on the Premises for the use
        designated in Section 7.01 above, nor connect with electrical current,
        except through existing electrical outlets in the Premises, or water
        pipes, any apparatus or device, for the purposes of using electric
        current or water.

                (b) If Tenant shall require water or electric current in excess
        of that usually furnished or supplied for use of the Premises, or for
        purposes other than those designated in Section 7.01 above, Tenant shall
        first procure the written consent of Landlord for the use thereof, which
        consent Landlord may refuse and/or Landlord may cause a water meter or
        electric current meter to be installed in the Leased Premises, so as to
        measure the amount of water and/or electric current consumed for any
        such use. The cost of such meters and of installation maintenance, and
        repair thereof shall be paid for by Tenant and Tenant agrees to pay
        Landlord promptly upon demand by Landlord for all such water and
        electric current consumed as shown by said meters, at the rates charged
        for such service by the City in which the Building is located or the
        local public utility, as the case may be, furnishing the same, plus any
        additional expense incurred in keeping account of the water and electric
        current so consumed.

                (c) If and where heat generating devices are used in the
        Premises which materially affect the temperature otherwise maintained by
        the air conditioning system, Landlord reserves the right to install
        additional or supplementary air conditioning units for the Premises, and
        the entire cost of installing operating, maintaining and repairing the
        same shall be paid by Tenant to Landlord promptly after demand by
        Landlord.

                To the extent that Tenant operates hours in excess of the stated
        standard business hours, Tenant may cause Landlord to provide services
        set forth in Section 12.01 (a), (b), (c) and (e) above; however, Tenant
        shall pay extra hourly utility charges as set forth in Section 1.01(S)
        herein. If electricity is metered pursuant to Section 3.03(c), then
        Tenant shall not be required to pay extra electrical charges as
        electrical usage during 'excess hours' will be metered and charged to
        Tenant in any case.

        SECTION 12.03 LIMITATIONS ON LANDLORDS LIABILITY. Landlord shall not be
liable for and Tenant shall not be entitled to terminate this Lease or to
effectuate any abatement or reduction of rent by reason of Landlord's failure to
provide or furnish any of the foregoing utilities or services if such failure
was reasonably beyond the control of Landlord. In no event shall Landlord be
liable for loss or injury to persons or property, however, arising or occurring
in connection with or attributable to any failure to furnish such utilities or
services even if within the control of Landlord.

                        Lease,
                (c)     that rent is paid currently without any off-set or
                        defense thereto,
                (d)     the amount of rent, if any paid in advance, and

attorn to the purchaser upon any such foreclosure or sale and recognize such
purchaser as the Landlord under this Lease.

        SECTION 13.03 SUBORDINATION. Tenant agrees that this Lease shall, at the
request of Landlord, be subordinate to any first mortgages or deeds of trust
that may hereafter be placed upon said Premises and to any and all advances to
be made thereunder, and to the interest thereon, and all renewals, replacements
and extensions thereof, provided the mortgagees or trustees named in said
mortgages or deeds of trust shall agree to recognize the Lease of Tenant in the
event of foreclosure, if Tenant is not in default and execute a non-disturbance
agreement in a form acceptable to Landlord's lender.

        SECTION 13.04 MORTGAGEE SUBORDINATION. Tenant hereby agrees that this
Lease shall, if at any time requested by Landlord or any lender in respect to
Landlord's financing of the building or project in which the Premises are
located or any portion hereof, be made superior to any mortgage or deed of trust
that may have preceded such Lease.

        SECTION 13.05 REMEDIES. Tenant hereby irrevocably appoints Landlord as
attorney-in-fact for the Tenant with full power and authority to execute and
deliver in the name of the Tenant any such instruments described in this Article
XIII upon failure of the Tenant to execute and deliver any of the above
instruments within fifteen (15) days after written request so to do by
Landlord; and such failure shall constitute a breach of this Lease entitling the
Landlord, at its option, to cancel this Lease and terminate the Tenant's
interest therein.


                             ARTICLE XIV. ASSIGNMENT

        SECTION 14.01 ASSIGNMENT. Tenant may assign or sublet all or any portion
of the Premises, or any part thereof for the same use permitted in Section 1.01
(F), provided that Tenant shall maintain continuing liability for all
obligations under this Lease. Tenant may not assign or sublet for any other use
without the written consent of Landlord, which consent will not be withheld

                    ARTICLE XVII. DESTRUCTION OF THE PREMISES

        SECTION 17.01 DESTRUCTION.

                (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



                                       12
<PAGE>   16

        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. Notwithstanding the above, if Landlord
        cannot reasonably restore the Premises to a tenantable condition within
        120 days after the occurrence of the casualty, then Landlord shall
        notify Tenant and Tenant may elect to terminate this Lease by giving
        written notice to Landlord within 10 days after receipt of Landlord's
        notice.


                (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 two years 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
        may at its option terminate this Lease Agreement by notice in writing to
        the Tenant within sixty (60) days after the date of such occurrence.
        Unless Landlord gives such notice, this Lease Agreement will remain in
        full force and effect subject to this Section 17.01 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 (b) 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, 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, 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 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 mailed to 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 mailed to Tenant, or if Tenant shall permit 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

                                       13
<PAGE>   17

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. If Tenant has abandoned the Premises and notices are not
deliverable to Tenant at the address provided by Tenant for notices, in lieu of
mailing, Landlord may conspicuously post such notice for ten (10) consecutive
days at the main entrance to or in front of the Premises, and such notice shall
constitute a good, sufficient, and lawful notice for the purpose of declaring a
forfeiture of this Lease and for terminating all of the rights of the Tenant
hereunder.

        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 reasonable 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 reasonable 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 worth at the time of such
termination of 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
then reasonable rental value of the Premises for the remainder of the stated
term, all of which amounts shall be immediately due and payable.

        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.

               ARTICLE XX. BANKRUPTCY, INSOLVENCY OR RECEIVERSHIP

        SECTION 20.01 ACT OF INSOLVENCY, GUARDIANSHIP, ETC. The following shall
constitute a default of this Lease by the Tenant for which Landlord, at
Landlord's option, may immediately terminate this Lease.

                (a) The appointment of a receiver to take possession of all or
        substantially all of the assets of the Tenant.

                (b) A general assignment by the Tenant of his assets for the
        benefit of creditors.

lessees of the Building, or to make all repairs, alterations, improvements or

including renewals or extensions.

        SECTION 23.02 SUCCESSORS. All rights and liabilities herein given to, or

                          ARTICLE XXV. QUIET ENJOYMENT

        SECTION 25.01 QUIET ENJOYMENT. Upon payment by the Tenant of the rents

                         ARTICLE XXVI. SECURITY DEPOSIT

        SECTION 26.01 SECURITY DEPOSIT. The Landlord herewith acknowledges
receipt of the amount set forth in Section 1.01 (U) 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 the Tenant's
failure to perform the said covenants, conditions and agreements; the Landlord
may so apply the Security Deposit, at its option; and the Landlord's right to
the possession of the Leased Premises for non-payment of rents or for other
reasons shall not in any event be affected by reason of the fact that the
Landlord holds this Security Deposit. The said sum, if not applied toward the
payment of rents 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 Tenant without interest when this
Lease is terminated, according to these terms, and in no event is the said
Security Deposit to be returned until Tenant has vacated the Leased Premises and

        In the event that the Landlord repossesses Leased Premises because of
the Tenant's default or because of the Tenant's failure to carry out the
covenants, conditions and agreements of this Lease, Landlord may apply the said
Security Deposit toward damages as may be suffered or shall accrue thereafter by
reason of the Tenant's default or breach. In the event of bankruptcy or other
debtor-creditor proceedings against Tenant as specified in Article XX, the
Security Deposit shall be deemed to be applied first to the payment of Rents and
other charges due Landlord for the earliest possible periods prior to the filing
of such proceedings. The Landlord shall not be obliged to keep the said Security
Deposit as a separate fund, but may mix the same with its own funds.


                     ARTICLE XXVII. MISCELLANEOUS PROVISIONS

        SECTION 27.01 WAIVER. No failure on the part of Landlord or Tenant to
enforce any covenant or provision of this Lease shall discharge or invalidate
such covenant or provision or affect the right of that party to enforce the same

condition by Landlord or Tenant 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 the other party. No breach of a
covenant or condition of this Lease shall be deemed to have been waived by
Landlord or Tenant, unless such waiver be in writing signed by the waiving
party.

        SECTION 27.03 FORCE MAJEURE. Any failure to perform or delay in
performance by either party of any obligation under this Lease, other than

period that such continues.

        SECTION 27.04 LOSS AND DAMAGE. The Landlord shall not be responsible or

his property from bursting, stoppage or leaking of water, gas sewer or steam
pipes or for any damage or loss of property within the Premises from any cause
whatsoever.

        SECTION 27.05 ACCORD AND SATISFACTION. No payment by Tenant or receipt
by Landlord of a lesser amount than the amount owing hereunder shall be deemed
to be other than on account of the earliest stipulated amount receivable from
Tenant, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment as rent be deemed an accord and satisfaction,
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

Landlord and Tenant.

itself, its heirs, executors, administrators and assigns and all persons
claiming under or through it, and this Lease is made and accepted upon and

against or segregation of any person or group of persons on account of race,
sex, marital status, color, creed, national origin or ancestry, in the leasing,
subleasing, assigning, use, occupancy, tenure or enjoyment of the Premises, nor
shall the Tenant itself, or any person claiming under or through it, establish
or permit any such practice or practices of discrimination or segregation with
reference to the selection, location, number, use or occupancy of tenants,
lessees, sublessees, or subtenants in the Premises.

        SECTION 27.08 SEVERABILITY. If any term, covenant or condition of this
Lease or the application thereof to any person or circumstance shall be invalid
or unenforceable to any extent, the remainder of this Lease, or the application
of such term, covenant or condition to persons or circumstances other than those
as to which it is held invalid or unenforceable, shall not be affected thereby
and each term, covenant or condition of this Lease shall be valid and be
enforced to the fullest extent permitted by law.

        SECTION 27.09 OTHER MISCELLANEOUS PROVISIONS. This instrument shall not
be recorded without the prior written consent of Landlord; however, upon the
