termination if the date of termination is thirty days or more after June 30,
1992, and the date Landlord receives Tenant's written demand.

         5. RENT.

                  a. Tenant agrees to pay to Landlord as basic rental, without
prior notice or demand, the sum of Seventy-Five Thousand Eight Hundred
Twenty-Eight Dollars ($75,828.00) commencing October 1, 1992, and a like sum on
or before the first day of each and every successive calendar month thereafter
during the term hereof, except that the first month's rent shall be paid upon
the execution hereof. Said rental shall be paid to Landlord, without deduction

tender at the time of payment at the 4843 Country Club Way, Boulder, Colorado
80301, or to such other person or at such other place as Landlord may from time
to time designate in writing.

                  b. On the first day of the month following the end of a Lease
year Landlord may increase the Base Rent payable for the subsequent twelve (12)
month period. The increase shall be measured by the increase in the Consumer
Price Index, as described below, but shall not exceed five percent (5%) of the
Base Rent owing for the immediately preceding year ("the 5% Cap"). The following
definitions and methods shall be used to calculate the increases in Base Rent
under this paragraph:

                  (1) "Consumer Price Index" shall mean the semi-annual indexes
                  of the Consumer Price Index for all Urban Consumers,
                  Denver-Boulder, Colorado (All Items; 1982-84 equals 100)
                  issued by the United States Department of Labor, Bureau of
                  Labor Statistics, or any successor agency of the United States
                  that issues such indexes or any successor index.

                  (2) "Initial Consumer Price Index" shall mean the Consumer
                  Price Index published for the nearest calendar period
                  preceding the Commencement Date of this Lease.

                  (3) "Latest Consumer Price Index" shall mean the Consumer
                  Price Index published for the nearest calendar period
                  preceding the first day on which an increase under this Lease
                  is to be effective.

                  (4) "Previous Consumer Price Index" shall mean the Consumer
                  Price Index published for the nearest calendar period
                  preceding the first day on which the previous increase under
                  this Lease was effective.

                  (5) The first increase will be calculated by multiplying the
                  Base Rent by a fraction, with the numerator being the Latest
                  Consumer Price Index and the denominator being the Initial
                  Consumer Price Index.

                  (6) Each subsequent increase will be calculated by multiplying
                  the then current Base Rent by a fraction, with the numerator
                  being the Latest Consumer Price Index and the denominator
                  being the Previous Consumer Price Index.




                                       2

                  (7) To the extent that the calculation under subparagraphs (5)
                  and (6) above exceed the 5% Cap, such excess ("Excess") shall
                  be preserved and carried forward to subsequent years until
                  utilized. All or part of the Excess may be added to the amount
                  calculated under subparagraph (6) above for any subsequent
                  year, subject to the 5% Cap.

                  (8) If the Consumer Price Index is discontinued, Landlord will
                  designate an alternative comparable index to be used in
                  calculating the increase in the Base Rent under this Lease.

                  (9) Tenant will not be entitled to a credit for any decrease
                  in the Consumer Price Index except to the extent that it shall
                  be off-set against any Excess carried forward under the
                  provisions of paragraph 5(b)(7).

                  c. Except as provided in subparagraph (a) of this paragraph,
notwithstanding any provision contained herein, the basic monthly rental due
under the terms hereof shall at no time be less than Seventy-Five Thousand Eight
Hundred Twenty-Eight Dollars ($75,828.00).

         6. SECURITY DEPOSIT. Tenant has deposited with Landlord the sum of
Ninety-Five Thousand Eight Hundred Forty-Four Dollars ($95,844.00). Said sum
shall be held by Landlord, without obligation for interest, as security for the
faithful performance by Tenant of all the terms, covenants, and conditions of
this Lease to be kept and performed by Tenant during the term hereof. If Tenant
defaults with respect to any provision of this Lease, including, but not limited
to the provisions relating to the payment of rent, Landlord may (but shall not
be required to) use, apply or retain all or any part of this security deposit
for the payment of any rent or any other sum in default, or for the payment of
any amount which Landlord may spend or become obligated to spend by reason of
Tenant's default, or to compensate Landlord for any other loss or damage which
Landlord may suffer by reason of Tenant's default. If any portion of said
deposit is so used or applied, Tenant shall within five (5) days after written
demand therefor, deposit cash with Landlord in an amount sufficient to restore
the security deposit to its original amount and Tenant's failure to do so shall
be a material breach of this Lease. Landlord shall not be required to keep this
security deposit separate from its general funds, and Tenant shall not be
entitled to interest on such deposit. If Tenant shall fully and faithfully
perform every provision of this Lease to be performed by it, the security
deposit or any balance thereof shall be returned to Tenant (or at Landlord's
option, to the last assignee of Tenant's interest hereunder) at the expiration
of the Lease term. In the event of termination of Landlord's interest in this
Lease, Landlord shall transfer said deposit to Landlord's successor in interest.

         7. OPERATING EXPENSES. For the purposes of this Article, operating
expenses means all reasonable and necessary costs and expenses of every kind and
nature, other than those expressly excluded below, paid or incurred by Landlord
in operating, managing, repairing, maintaining and administering the Building
including, without limitation or duplication:

life of such capital improvement or structural repair or replacement (as
reasonably determined by Landlord) together with interest on the balance of the

                  b. The cost of repairs, replacements or other work occasioned

                  c. Any fees paid for management of the Property.

                  d. Leasing commissions, advertising expenses and other costs

                  g. Any Operating Expense that Landlord and Tenant have agreed
that Tenant shall pay directly.

         Tenant shall pay 100.00% of Operating Expenses paid or incurred by the
Landlord for the operation or maintenance of the Building of which the Premises
are a part. Upon commencement of this Lease, Landlord shall give Tenant a
statement of the amount of Operating Expenses payable by Tenant with each
payment of rent, which shall be based upon a best estimate of such expenses if
no record of actual expenses for the prior year are available. Landlord shall
endeavor to give to Tenant on or before the first day of March of each year
thereafter a statement of the increase in Operating Expenses payable by Tenant
hereunder, but failure by Landlord to give such statement by said date shall not
constitute a waiver by Landlord of its right to require an increase in Operating
Expenses. The total amount of actual Operating Expenses for the prior year shall
be used as an estimate for current year and this amount shall be divided into
twelve (12) equal monthly installments, and Tenant shall pay to Landlord,
concurrently with the regular monthly rent payment next due following the
receipt of such statement, an amount equal to one (1) monthly installment
multiplied by the number of months







                                       5
<PAGE>   6

from January in the calendar year in which said statement is submitted to the
month of such payment. Subsequent installments shall be payable concurrently
with the regular monthly rent payments for the balance of that calendar year and
shall continue until the next year's statement is rendered. If Operating
Expenses are more than estimated, then upon receipt of a statement from
Landlord, Tenant shall pay a lump sum equal to such total increase with the
regular monthly rent payment.

         Even though the term has expired and Tenant has vacated the Premises,
when the final determination is made of Tenant's share of Operating Expenses for
the year in which this Lease terminates, Tenant shall immediately pay any
increase due over the estimated expenses paid and, conversely, any overpayment
made in the event said expenses decrease shall be immediately rebated by
Landlord to Tenant.

         8. USE. Tenant shall use the Premises for office, laboratories, light
manufacturing and service to products manufactured by Tenant, and shall not use
or permit the Premises to be used for any other purpose without the prior
written consent of Landlord. Tenant shall refrain from the sale of merchandise
or the performance of services not usually incidental to such business.

         Tenant shall not do or permit anything to be done in or about the
Premises nor bring or keep anything therein which will in any way increase the
existing rate or affect any fire or other insurance upon the Building or any of
its contents, or cause cancellation of any insurance policy covering said
Building or any part thereof or any of its contents. Tenant shall not do or
permit anything to be done in or about the Premises which will, in any way,
obstruct or interfere with the rights of other tenants or occupants of the
Building or injure or annoy them or use or allow the Premises to be used for any
improper, immoral, unlawful or objectionable purpose, nor shall Tenant cause,
maintain or permit any nuisance in, on or about the Premises. Tenant shall not
commit or suffer to be committed any waste in or upon the Premises.

         9. COMPLIANCE WITH LAW. Tenant shall not use the Premises or permit
anything to be done in or about the Premises which will, in any way, conflict
with any law, statute, ordinance or governmental rule or regulation now in force
or which may hereafter be enacted or promulgated. Tenant shall, at its sole cost
and expense, promptly comply with all laws, statutes, ordinances and
governmental rules, regulations or requirements now in force or which may
hereafter be in force, and with the requirements of any board of fire insurance
underwriters or other similar bodies now or hereafter constituted, relating to,
or affecting the condition, use or occupancy of the Premises, excluding
structural changes not related to or affected by Tenant's improvements or acts.
The judgment against Tenant, whether the Landlord be a party thereto or not,
that Tenant has violated any law, statute, ordinance or governmental rule,
regulation or requirement, shall be conclusive of that fact as between the
Landlord and Tenant.

         10. ALTERATIONS AND ADDITIONS. Tenant shall not make or suffer to be
made any alterations, additions or improvements to or of the Premises or any
part thereof that exceed a cost of Fifteen Thousand Dollars ($15,000.00) for a
single project





                                       6
<PAGE>   7

or system or change the exterior or the structure of the Premises, without the
prior written consent of Landlord first had and obtained, and any alterations,
additions or improvements to or of said Premises, including, but not limited to,
wall covering, paneling and built-in cabinet work, but excepting movable
furniture and trade fixtures, shall, on the expiration of the term, become a
part of the realty and belong to the Landlord and shall be surrendered with the
Premises. Tenant, at its own cost and expense, make erect such shelves, bins,
machinery and trade fixtures as it desires, provided that (a) such items do not
alter the basic structure of the Premises; (b) such items do not overload or
damage the Premises; (c) such items may be removed without injury to the
Premises; and (d) the construction, erection or installation thereof complies
with all applicable governmental laws, ordinances, regulations and with
Landlord's specifications and requirements. In the event Landlord consents to
the making of any alterations, additions or improvements to the Premises by
Tenant, the same shall be made by Tenant at Tenant's sole cost and expense, and
any contractor or person selected by Tenant to make the same, must first be
approved of in writing by the Landlord. Upon the expiration or earlier
termination of the term hereof, Tenant shall, upon the written demand by the
Landlord, at Tenant's sole cost and expense, forthwith and with all due
diligence, remove any alterations, additions, or improvements made which have
been designated by the Landlord to be removed, and repair any damage to the
Premises caused by such removal. All installations, removals and restoration
shall be performed in a good and workmanlike manner so as not to damage or alter
the primary structure or structural qualities of the Premises.

         11. REPAIRS.

                  a. By taking possession of the Premises, Tenant shall be
deemed to have accepted the Premises as being in good, sanitary order, condition
and repair. Tenant shall, at Tenant's sole cost and expense, keep the Premises
and every part thereof in good condition and repair, damage thereto from causes
beyond the reasonable control of Tenant and ordinary wear and tear excepted. In
addition, Tenant is responsible for causing the parking areas, driveways, alleys
and grounds surrounding the Premises to be maintained in a good, neat, clean and
sanitary condition, which includes without limitation (1) promptly making all
necessary repairs and replacements thereto, (2) repaving of the parking areas
associated with the Premises, (3) maintenance and replacement of all grass,
shrubbery and other landscape treatments surrounding the Premises, (4)
maintenance and repainting of the exterior of he Premises, (5) sewage line
plumbing, and (6) any other maintenance items normally associated with the
foregoing. Tenant shall, upon the expiration or sooner termination of this Lease
hereof, surrender the Premises to the Landlord in good condition, ordinary wear
and tear and damage from causes beyond the reasonable control of Tenant
excepted. Except as specifically provided in an addendum, if any, to this Lease,
Landlord shall have no obligation whatsoever to alter, remodel, improve, repair,
decorate or paint the Premises or any part thereof, and the parties hereto
affirm that Landlord has made no representations to Tenant respecting the
condition of the Premises or the Building except as specifically herein set
forth.



                                       7
<PAGE>   8

                  b. Tenant, at its own cost and expenses, shall cause to be
performed, in accordance with standards reasonably suitable to Landlord,
regularly scheduled preventive maintenance and services on all hot water,
heating and air conditioning systems and equipment within the Premises. Such
maintenance and services, of the new systems to be installed, must include all
service suggested by the equipment manufacturers in their operations/maintenance
manuals and must become effective within thirty (30) days of the date Tenant
takes possession of the Premises. If Tenant fails, with any reasonable time, to
perform Tenant's maintenance, repair and replacement obligations and any other
items that are otherwise its obligations under the terms of this Lease, then
Landlord reserves the right to perform such obligations and require
reimbursement from Tenant upon demand.

                  c. Landlord shall repair and maintain the structural portions
of the Building unless such maintenance and repairs are caused in part or in
whole by the act, neglect, fault or omission of any duty by the Tenant, its
agents, servants, employees or invitees, in which case Tenant shall pay to
Landlord the reasonable cost of such maintenance and repairs. The cost of all
such repairs (except repairs of structural defects) shall be included in
Operating Expenses as provided in Article 7 hereof. Landlord shall not be liable
for any failure to make any such repairs or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. Except as
provided in Article 22 hereof, there shall be no abatement of rent and no
liability of Landlord by reason of any injury to or interference with Tenant's
business arising from the making of any repairs, alterations or improvements in
or to any portion of the Building or the Premises or in or to fixtures,
appurtenances and equipment therein. Tenant waives the right to make repairs at
Landlord's expense under any law, statute or ordinance now or hereafter in
effect.

         12. LIENS. Tenant shall keep the Premises and the property in which the
Premises are situated free from any liens arising out of any work performed,
materials furnished or obligations incurred by Tenant. Landlord may require, if
reasonably concerned about Tenant's ability to satisfy any lien, at Landlord's
sole option, that Tenant shall provide to Landlord, at Tenant's sole cost and
expense, a lien and completion bond in an amount equal to one and one-half
(1-1/2) times any and all estimated costs of improvements, additions, or
alterations in the Premises, to insure Landlord against any liability for
mechanics' and materialmen's liens and to insure completion of the work.

         13. ASSIGNMENT AND SUBLETTING.

                  a. Tenant shall not either voluntarily or by operation of law,
assign, transfer, mortgage, pledge, hypothecate or encumber this Lease or any
interest therein, and shall not sublet the said Premises or any part thereof, or
any right or privilege appurtenant thereto, or suffer any other person (the
employees, agents, servants and invitees of Tenant excepted) to occupy or use
the said Premises, or any portion thereof, without the written consent of
Landlord first had and obtained, which consent shall not be unreasonably
withheld; provided, however, Tenant shall have the right to sublet





                                       8
<PAGE>   9

without the written consent of Landlord, either (1) for the same uses as
described in paragraph 8 if no alterations to the improvements will be made, or
(2) in any event, if Tenant returns the sublet portion of the Premises to the
condition that existed prior to the subletting. A consent to one assignment,
subletting, occupation or use by any other person shall not be deemed to be a
consent to any subsequent assignment, subletting, occupation or use by another
person. Any such assignment or subletting without such consent shall be void,,
and shall, at the option of the Landlord, constitute a default under this Lease;
provided, however, Tenant shall have the right to assign this Lease to its
parent, subsidiary, or successor (succeeds to all assets of Tenant) corporation.
Landlord may consider many factors in determining whether or not to consent,
including but not limited to the type of business to be operated by the proposed
sublessee and sublessee's credit worthiness and financial status. No assignment,
subletting or other transfer, whether consented to by Landlord or not, or
permitted hereunder, shall relieve Tenant of its liability under this Lease. If
an event of default occurs while the Premises or any part thereof are assigned
or sublet, then Landlord, in addition to any other remedies provided under this
Lease or by law, may collect directly from such assignee, sublessee or
transferee all rents payable to the Tenant and apply such rent against any sums
due Landlord hereunder. No such collection shall be construed to constitute a
novation or release of the Tenant from the further performance of Tenant's
obligations under this Lease.

                  b. If this Lease is assigned to any person or entity pursuant
to the provisions of the Bankruptcy Code, 11 U.S.C. Section 101 et. seq., (the
"Bankruptcy Code"), any and all monies or other consideration payable or
otherwise to be delivered in connection with such assignment shall be paid or
delivered to Landlord, shall be and remain the exclusive property of Landlord
and shall not constitute property of Tenant or of the estate of Tenant within
the meaning of the Bankruptcy Code. Any and all monies or other considerations
constituting Landlord's property under the preceding sentence not paid or
delivered to Landlord shall be held in trust for the benefit of Landlord and be
promptly paid or delivered to Landlord.

                  c. Any person or entity to which this Lease is assigned
pursuant to the provisions of the Bankruptcy Code shall be deemed, without
further act or deed, to have assumed all of the obligations arising under this
Lease on and after the date of such assignment. Any such assignee shall upon
demand execute and deliver to Landlord an instrument confirming such assumption.
The assignor in such situation, however, shall not be released from any
obligation under this Lease except in a specific, written release signed by
Landlord.

         14. HOLD HARMLESS. Tenant shall indemnify and hold harmless Landlord
against and from any and all claims arising from Tenant's use of the Premises
for the conduct of its business or from any activity, work, or other thing done,
permitted or suffered by the Tenant in or about the Building, and shall further
indemnify and hold harmless Landlord against and from any and all claims arising
from any breach or default in the performance of any obligation on Tenant's part
to be performed under the terms of this Lease, or arising from any act or
negligence of the Tenant, or any officer, agent, employee, guest, or invitee of
Tenant, and from all and against all costs,





                                       9

attorneys' fees, expenses and liabilities incurred in or about any such claim or
any action or proceeding brought thereon, and, in any case, action or proceeding
be brought against Landlord by reason of any such claim, Tenant, upon notice
from Landlord shall defend the same at Tenant's expense by counsel reasonably
satisfactory to Landlord. Tenant, as a material part of the consideration to
Landlord, hereby assumes all risk of damage to property or injury to persons,
in, upon or about the Premises, from any cause other than Landlord's negligence,
and Tenant hereby waives all claims in respect thereof against Landlord.
Landlord or its agents shall not be liable for any damage to property entrusted
to employees of the Building, nor for loss or damage to any property by theft or
otherwise, nor for any injury to or damage to persons or property resulting from
fire, explosion, falling plaster, steam, gas, electricity, water or rain which
may leak from any part of the Building or from the pipes, appliances or plumbing
works therein or from the roof, street or subsurface or from any other place
resulting from dampness or any other cause whatsoever, unless caused by or due
to the negligence of Landlord, its agents, servants or employees. Landlord or
its agents shall not be liable for interference with the light or other
incorporeal hereditaments, loss of business by Tenant, nor shall Landlord be
liable for any latent defects in the Premises or in the Building. Tenant shall
give prompt notice to Landlord in case of fire or accidents in the Premises or
in the Building or of defects therein or in the fixtures or equipment.

         15. SUBROGATION. As long as their respective insurers so permit,
Landlord and Tenant hereby mutually waive their respective rights of recovery
against each other for any loss insured by fire, extended coverage and other
property insurance policies existing for the benefit of the respective parties.
Each party shall obtain any special endorsements, if required by their insurer
to evidence compliance with the aforementioned waiver.

         16. LIABILITY INSURANCE. Tenant shall, at Tenant's expense, obtain and
keep in force during the term of this Lease a policy or policies of worker's
compensation and comprehensive general liability insurance, including personal
injury and property damage in the amount of One Million Dollars ($1,000,000.00)
verified per occurrence for property damage and One Million Dollars
($1,000,000.00) verified per occurrence for personal injuries or death of
persons occurring in or about the Premises. The limit of said insurance shall
not, however, limit the Liability of the Tenant hereunder. Tenant may carry said
insurance under a blanket policy, providing, however, said insurance by Tenant
shall have a Landlord's protective liability endorsement attached thereto. If
Tenant shall fail to procure and maintain said insurance, Landlord may, but
shall not be required to, procure and maintain same, but at the expense of
Tenant. Insurance required hereunder, shall be in companies rated A+, AAA or
better in "Best's Insurance Guide." Tenant shall deliver to Landlord prior to
occupancy of the Premises copies of policies of liability insurance required
herein or certificates evidencing the existence and amounts of such insurance
with loss payable clauses satisfactory to Landlord. No policy shall be
cancelable or subject to reduction of coverage except after ten (10) days' prior
written notice to Landlord.

         17. PROPERTY TAXES. Tenant shall pay, or cause to be paid, before
delinquency, any and all taxes levied or assessed and which become payable
during the






                                       10
<PAGE>   11

term hereof upon all Tenant's leasehold improvements, equipment, furniture,
fixtures and personal property located in the Premises; except that which has
been paid for by Landlord, and is the standard of the Building. In the event any
or all of Tenant's leasehold improvements, equipment, furniture, fixtures and
personal property shall be assessed and taxed with the Building, Tenant shall
pay to Landlord its share of such taxes within ten (10) days after delivery to
Tenant by Landlord of a statement in writing setting forth the amount of such
taxes applicable to Tenant's property.

         18. RULES AND REGULATIONS. Tenant shall faithfully observe and comply
with the reasonable rules and regulations that Landlord shall, from time to
time, promulgate. Landlord reserves the right, from time to time, to make all
reasonable modifications to said rules. The additions and modifications to those
rules shall be binding upon Tenant upon delivery of a copy of them to Tenant.
Landlord shall not be responsible to Tenant for the nonperformance of any said
rules by any other tenants or occupants.

         19. HOLDING OVER. If Tenant remains in possession of the Premises or
any part after the expiration of the term hereof, without the express written
consent of Landlord, such occupancy shall be a tenancy from month-to-month at a
rental in the amount of the last monthly rental, plus all other charges payable
hereunder, and upon all the terms hereof applicable to a month-to-month tenancy.

         20. ENTRY BY LANDLORD. Landlord reserves, and shall at any and all
times, have the right to enter the Premises, inspect the same, supply janitorial
service and any other service to be provided by Landlord to Tenant hereunder, to
submit said Premises to prospective purchasers or tenants, to post notices of
non-responsibility, and to alter, improve or repair the Premises and any portion
of the Building of which the Premises are a part that Landlord may deem
necessary or desirable, without abatement of rent and may for that purpose erect
scaffolding and other necessary structures where reasonably required by the
character of the work to be performed, always providing that the entrance to the
Premises shall not be blocked thereby, and further providing that the business
of the Tenant shall not be interfered with unreasonably. Tenant hereby waives
any claim for damages or for any injury or inconvenience to or interference with
Tenant's business, any loss of occupancy or quiet enjoyment of the Premises, and
any other loss occasioned thereby. For each of the aforesaid purposes, Landlord
shall, at all times, have and retain a key with which to unlock all of the doors
in, upon and about the Premises, excluding Tenant's vaults, safes and files, and
Landlord shall have the right to use any and all means which Landlord may deem
proper to open said doors in an emergency, in order to obtain entry to the
Premises without liability to Tenant except for any failure to exercise due care
for Tenant's property. Any entry to the Premises obtained by Landlord by any of
said means, or otherwise shall not, under any circumstances, be construed or
deemed to be a forcible or unlawful entry into, or a detainer of, the Premises,
or an eviction of Tenant from the Premises or any portion thereof. It is
understood and agreed that if Landlord enters the Premises at anytime, with or
without a representative of Tenant being present, Landlord and its




                                       11
<PAGE>   12

representatives shall be subject to usual and customary duties of non-disclosure
of any information obtained as a result of such entry.

         21. RECONSTRUCTION. In the event the Premises or the Building of which
the Premises are a part are damaged by fire or other perils covered by extended
coverage insurance, Landlord agrees to forthwith repair the same; and this Lease
shall remain in full force and effect, except that the Tenant shall be entitled
to a proportionate reduction of the rent while such repairs are being made, such
proportionate reduction to be based upon the extent to which the making of such
repairs shall materially interfere with the business carried on by the Tenant in
the Premises. If the damage is due to the fault or neglect of Tenant or its
employees, there shall be no abatement of rent.

         In the event the Premises or the Building of which the Premises are a
part are damaged as a result of any cause other than the perils covered by fire
and extended coverage insurance, then Landlord shall forthwith repair the same,
provided the extent of the destruction be less than ten percent (10%) of the
then full replacement cost of the Premises or the Building of which the Premises
are a part. In the event the destruction of the Premises or the Building is to
an extent greater than ten percent (10%) of the full replacement cost, then
Landlord shall have the option: (1) to repair or restore such damage, this Lease
continuing in full force and effect, but the rent to be proportionately reduced
as hereinabove in this Article provided; or (2) give notice to Tenant at any
time within sixty (60) days after such damage terminating this Lease as of the
date specified in such notice, which date shall be no less than thirty (30) and
no more than sixty (60) days after the giving of such notice. In the event of
giving such notice, this Lease shall expire and all interest of the Tenant in
the Premises shall terminate on the date so specified in such notice and the
Rent, reduced by a proportionate amount, based upon the extent, if any, to which
such damage materially interfered with the business carried on by the Tenant in
the Premises, shall be paid up to date of said such termination. Notwithstanding
anything to the contrary contained in this Article, Landlord shall not have any
obligation whatsoever to repair, reconstruct or restore the Premises when the
damage resulting from any casualty covered under this Article occurs during the
last twelve (12) months of the term of this Lease or any extension thereof. If
Landlord elects to restore the Premises, the restoration must be completed
within a reasonable period time after the destruction taking into consideration
the extent of destruction and all other facts and circumstances relating to the
destruction and reconstruction.

         Landlord shall not be required to repair any injury or damage by fire
or other cause, or to make any repairs or replacements of any panels,
decoration, office fixtures, railings, floor coverings, partitions, or any other
property installed in the Premises by Tenant.

         The Tenant shall not be entitled to any compensation or damages from
Landlord for loss of the use of the whole or any part of the Premises, Tenant's
personal property or any inconvenience or annoyance occasioned by such damage,
repair, reconstruction or restoration.




                                       12
<PAGE>   13

         22. DEFAULT. The occurrence of any one or more of the following events
shall constitute a default and breach of this Lease by Tenant:

                  a. The vacating or abandonment of the Premises by Tenant.

                  b. The failure by Tenant to make any payment of rent or any
other payment required to be made by Tenant hereunder, as and when due, where
such failure shall continue for a period of five (5) days after payment is due.
If Tenant is late in tendering said rental payment twice during any Lease Year
or if the funds paid are not collectable at any time, Landlord is granted the
right to require all future rental payments in cash or certified funds.

                  c. The failure by Tenant to observe or perform any of the
covenants, conditions or provisions of this Lease to be observed or performed
by the Tenant, other than described in Article 23.b above, where such failure
shall continue for a period of ten (10) days after written notice thereof by
Landlord to Tenant; provided, however, that if the nature of Tenant's default is
such that more than ten (10) days are reasonably required for its cure, then
Tenant shall not be deemed to be in default if Tenant commences such cure within
said ten (10) day period and thereafter diligently prosecutes such cure to
completion.

                  d. The making by Tenant of any general assignment or general
arrangement for the benefit of creditors; or the filing by or against Tenant of
a petition to have Tenant adjudged a bankrupt, or a petition of reorganization
or arrangement under any law relating to bankruptcy (unless, in the case of a
petition filed against Tenant, the same is dismissed within sixty [60] days); or
the appointment of a trustee or a receiver to take possession of substantially
all of Tenant's assets located at the Premises or of Tenant's interest in this
Lease, where possession is not restored to Tenant within thirty (30) days; or
the attachment, execution or other judicial seizure of substantially all of
Tenant's assets located at the Premises or of Tenant's interest in this Lease,
where such seizure is not discharged in thirty (30) days.

         23. REMEDIES IN DEFAULT. In the event of any such default or breach by
Tenant, Landlord may at any time thereafter, with or without notice or demand,
and without limiting Landlord in the exercise of a right or remedy which
Landlord may have by reason of such default or breach:

                  a. Terminate Tenant's right to possession of the Premises by
any lawful means, in which case this Lease shall terminate and Tenant shall
immediately surrender possession of the Premises to Landlord. In such event
Landlord shall be entitled to recover from Tenant all damages incurred by
Landlord by reason of Tenant's default including, but not limited to, the cost
of recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
any real estate commission actually paid; the worth at the time of award by the
court having jurisdiction thereof of the amount by which the unpaid rent for the
balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Tenant proves could be reasonably avoided;



                                       13
<PAGE>   14

that portion of the leasing commission paid by Landlord and applicable to the
unexpired term of the Lease. Unpaid installments of rent or other sums shall
bear interest from the date due at the rate of twenty percent (20%) per annum.
In the event Tenant shall have abandoned the Premises, Landlord shall have the
option of (a) taking possession of the Premises and recovering from Tenant the
amount specified in this paragraph, or (b) proceeding under the provisions of
subparagraph b of this paragraph.

                  b. Maintain Tenant's right to possession, in which case this
Lease shall continue in effect whether or not Tenant shall have abandoned the
Premises. In such event, Landlord shall be entitled to enforce all of Landlord's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

                  c. If no security deposit has been previously made, demand
that a security deposit equal to two months rent be paid immediately to
Landlord.

                  d. Pursue any other remedy now or hereafter available to
Landlord under the laws or judicial decision of the State in which the Premises
are located.

         24. EMINENT DOMAIN. If more than fifty percent (50%) of the Premises
shall be taken or appropriated by any public or quasi-public authority under the
power of eminent domain, either party hereto shall have the right, at its
option, to terminate this Lease, and Landlord shall be entitled to any and all
income, rent, award, or any interest therein whatsoever which may be paid or
made in connection with such public or quasi-public use or purpose, and Tenant
shall have no claim against Landlord for the value of any unexpired term of this
Lease. If either less than or more than fifty percent (50%) of the premises is
taken, and neither party elects to terminate as herein provided, the rental
thereafter to be paid shall be equitably reduced. If any part of the Building
other than the Premises may be so taken or appropriated, Landlord shall have the
right at its option to terminate this Lease and shall be entitled to the entire
award as above provided.

         25. ESTOPPEL STATEMENT. Tenant shall at any time and from time to time
upon not less than ten (10) days' prior written notice from Landlord execute,
acknowledge, and deliver to Landlord a statement in writing, (a) certifying that
this Lease is unmodified and in full force and effect (or, if modified, stating
the nature of such modification and certifying that this Lease as so modified,
is in full force and effect), and the date to which the rental and other charges
are paid in advance, if any, and (b) acknowledging that there are not, to
Tenant's knowledge, any uncured defaults on the part of the Landlord hereunder,
or specifying such defaults if any are claimed. Any such statement may be relied
upon by any prospective purchaser or encumbrancer of all or any portion of the
real property of which the Premises are a part.

         26. PARKING. Tenant shall have the right to use in common with other
tenants or occupants of the Building the parking facilities of the Building, if
any, subject to the reasonable rules and regulations for such parking facilities
which may be established or altered by Landlord at any time or from time to time
during the term hereof. Landlord shall mark parking spaces for the specific use
of all tenants only when






                                       14
<PAGE>   15

necessary to avoid conflict among tenants. Landlord shall not be responsible for
enforcing Tenant's parking right against third parties. Tenant agrees not to use
more parking spaces that so provided. Tenant shall be entitled to not less than
490 parking spaces.

         27. AUTHORITY OF PARTIES. Each individual executing this Lease on
behalf of Tenant represents and warrants that he is duly authorized to execute
and deliver this Lease on behalf of the corporation, in accordance with a duly
adopted resolution of the board of directors of said corporation or in
accordance with the bylaws of said corporation, and that this Lease is binding
upon said corporation in accordance with its terms.

         28. HAZARDOUS MATERIALS AND ENVIRONMENTAL CONSIDERATIONS.

                  a. Tenant covenants and agrees that Tenant and its agents,
employees, contractors and invitees shall comply with all Hazardous Materials
Laws (as hereinafter defined) as they apply to this property. Without limiting
the foregoing, Tenant covenants and agrees that it will not use, generate, store
or dispose of, nor permit the use, generation, storage or disposal of Hazardous
Materials (as hereinafter defined) on, under or about the Leased Premises, nor
will it transport or permit the transportation of Hazardous Materials to or from
the Leased Premises, except in full compliance with any applicable Hazardous
Materials Laws. Any Hazardous Materials located on the Leased Premises shall be
handled in an appropriately controlled environment which shall include the use
of such equipment (at Tenant's expense) as is necessary to meet or exceed
standards imposed by any Hazardous Materials Laws and in such a way as not to
interfere with any other tenant's use of its premises. Upon breach of any
covenant contained herein, Tenant shall, at Tenant's sole expense, cure such
breach by taking all action prescribed by any applicable Hazardous Materials
Laws or by any governmental authority with jurisdiction over such matters.

                  b. Tenant shall inform Landlord at any time of (1) any
Hazardous Materials it intends to use, generate, handle, store or dispose of,
on or about or transport from, the Leased Premises and (ii) of Tenant's
discovery of any event or condition which constitutes a violation of any
applicable Hazardous Materials Laws. Tenant shall provide to Landlord copies of
all communications to or from any governmental authority or any other party
relating to Hazardous Materials affecting the Leased Premises.

                  c. Tenant shall indemnify and hold Landlord harmless from any
and all claims, judgments, damages, penalties, fines, costs, liabilities,
expenses or losses (including, without limitation, diminution on value of the
Leased Premises, damages for loss or restriction on use of all or part of the
Leased Premises, sums paid in settlement of claims, investigation of site
conditions, or any cleanup, removal or restoration work required by any federal,
state or local governmental agency, attorney's fees, consultant fees and expert
fees) which arise as a result of or in connection with any breach of the
foregoing covenants or any other violation contained herein shall also accrue to
the benefit of the employees, agents, officers, directors and/or partners of
Landlord.




                                       15
<PAGE>   16

                  d. Upon termination of this Lease and/or vacation of the
Leased Premises, Tenant shall properly remove all Hazardous Materials and shall
thereafter, within a reasonable period of time, provide to Landlord an
environmental audit report, prepared by a professional consultant satisfactory
to Landlord and at Tenant's sole expense, certifying that the Leased Premises
have not been subjected to environmental harm caused by Tenant's use and
occupancy of the Leased Premises, Tenant shall at all times be entitled a copy
of any environmental audit reports which Landlord may have obtained. Landlord
shall grant to Tenant and its agents or contractors such access to the Leased
Premises as is necessary to accomplish such removal and prepare such report.

                  e. "Hazardous Materials" shall mean (a) any chemical,
material, substance or pollutant which poses a hazard to the Leased Premises or
to persons on or about the Leased Premises or would cause a violation of or is
regulated by any Hazardous Materials Laws, and (b) any chemical, material or
substance defined as or included in the definitions of "hazardous substances,"
"hazardous wastes," "hazardous materials," "extremely hazardous waste,"
"restricted hazardous waste," "toxic substances," "regulated substances," or
words of similar import under any applicable federal, state or local law or
under the regulations adopted or publications promulgated pursuant thereto,
including, but not limited to, the Comprehensive Environmental Response.
Compensation and Liability Act of 1980, as amended, 42 U.S.C. Sec. 9601, et
seq.; the Hazardous Materials Transportation Act, as amended, 49 U.S.C. Sec.
1801, et seq.; the Resource Conservation and Recover Act, as amended, 42 U.S.C.
Sec. 6901, et seq.; the Solid Waste Disposal Act, 42 U.S.C. Sec. 6991 et seq.;
the Federal Water Pollution Control Act, as amended, 33 U.S.C. Sec. 1251, et
seq., of the Colorado Revised Statutes. "Hazardous Materials Laws" shall mean
any federal, state or local laws, ordinances, rules, regulations, or policies
(including, but not limited to, those laws specified above) relating to the
environment, health and safety or the use, handling, transportation, production,
disposal, discharge or storage of Hazardous Materials, or to industrial hygiene
or the environmental conditions on, under or about the Leased Premises. Said
term shall be deemed to include all such laws as are now in effect or as
hereafter amended and all other such laws as may hereafter be enacted or adopted
during the term of this Lease.

                  f. All obligations of Tenant hereunder shall survive and
continue after the expiration of this Lease or its earlier termination for any
reason.

                  g. Tenant further covenants and agrees that it shall not
install any storage tank (whether above or below the ground) on the Leased
Premises without obtaining the prior written consent of the Landlord, which
consent may be conditioned upon further requirements imposed by Landlord with
respect to, among other things, compliance by Tenant with any applicable laws,
rules, regulations or ordinances and safety measures or financial responsibility
requirements.

         29. GENERAL PROVISIONS.

                  a. Plats and Riders. Clauses, plats and riders, if any, signed
by the Landlord and the Tenant and endorsed on or affixed to this Lease are a
part hereof.




                                       16
<PAGE>   17

                  b. Waiver. The waiver by Landlord of any term, covenant, or
condition herein contained shall not be deemed to be a waiver of such term,
covenant or condition or any subsequent breach of the same or any other term,
covenant or condition herein contained. The subsequent acceptance of rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
by Tenant of any term, covenant or condition of this Lease, other than the
failure of the Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of the acceptance of
such rent.

                  c. Notices. All notices and demands which may or are to be
required or permitted to be given by either party to the other hereunder shall
be in writing. All notices and demands by the Landlord to the Tenant shall be
sent by United States Mail, postage prepaid, addressed to the Tenant at the
Premises, or to such other place as Tenant may, from time to time, designate in
a notice to the Landlord. All notices and demands by the Tenant to the Landlord
shall be sent by United States Mail, postage prepaid, addressed to the Landlord
at the Office of the Building, or to such other person or place as the Landlord
may, from time to time, designate in a notice to the Tenant.

                  d. Joint obligation. If there be more than one Tenant the
obligations hereunder imposed upon Tenants shall be joint and several.

                  e. Marginal Headings. The marginal headings and Article titles
to the Articles of this Lease are not a part of this Lease and shall have no
effect upon the construction or interpretation of any part hereof.

                  f. Time. Time is of the essence of this Lease and each and all
of its provisions in which performance is a factor.

                  g. Successors and Assigns. The covenants and conditions herein
contained, subject to the provisions as to assignment, apply to and bind the
heirs, successors, executors, administrators and assigns of the parties hereto.

                  h. Recordation. Neither the Landlord nor Tenant shall record
this Lease or a short form memorandum hereof without the prior written consent
of the other party.

                  i. Quiet Possession. Upon Tenant paying the rent reserved
hereunder and observing and performing all of the covenants, conditions and
provisions of Tenant's part to be observed and performed hereunder, Tenant shall
have quiet possession of the Premises for the entire term hereof, subject to all
the provisions of this Lease.

                  j. Late Charges. Tenant hereby acknowledges that late payment
by Tenant to Landlord of rent or other sums due hereunder will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed upon
Landlord by terms of any mortgage or trust deed covering the Premises.
Accordingly, if any installment of



                                       17
<PAGE>   18
rent or of a sum due from Tenant shall not be received by Landlord or Landlord's
designee within five (5) days after said amount is due, then Tenant shall pay to
Landlord a late charge equal to five percent (5%) of such overdue amount. The
parties hereby agree that such late charges represent a fair and reasonable
estimate of the cost that Landlord will incur by reason of the late payment by
Tenant. Acceptance of such late charges by the Landlord shall in no event
constitute a waiver of Tenant's default with respect to such overdue amount, nor
prevent Landlord from exercising any of the other rights and remedies granted
hereunder.

                  k. Prior Agreements. This Lease contains all of the agreements
of the parties hereto with respect to any matter covered or mentioned in this
Lease, and no prior agreements or understanding pertaining to any such matters
shall be effective for any purpose. No provision of this Lease may be amended or
added to except by an agreement in writing signed by the parties hereto or their
respective successors in interest. This Lease shall not be effective or binding
on any party until fully executed by both parties hereto.

                  l. Attorneys' Fees. In the event of any action or proceeding
brought by either party against the other under this Lease, the prevailing party
shall be entitled to recover all costs and expenses, including the fees of its
attorneys in such action or proceeding in such amount as the court may adjudge
reasonable as attorneys' fees.

                  m. Sale of Premises by Landlord. In the event of any sale of
the Building, Landlord shall be and is hereby entirely freed and relieved of all
liability under any and all of its covenants and obligations contained in or
derived from this Lease arising out of any act, occurrence or omission occurring
after the consummation of such sale; and the purchaser, at such sale or any
subsequent sale of the Premises, shall be deemed, without any further agreement
between the parties or their successors in interest or between the parties and
any such purchaser, to have assumed and agreed to carry out any and all of the
covenants and obligations of the Landlord under this Lease.

                  n. Subordination, Attornment. Upon request of the Landlord,
Tenant will, in writing, subordinate its rights hereunder to the lien of any
first mortgage or first deed of trust to any bank, insurance company or other
lending institution, now or hereafter in force against the land and Building of
which the Premises are a part, and upon any buildings hereafter placed upon the
land of which the Premises are a part, and to all advances made or hereafter to
be made upon the security thereof.

                  In the event any proceedings are brought for foreclosure, or
in the event of the exercise of the power of sale under any mortgage or deed of
trust made by the Landlord covering the Premises, the Tenant shall attorn to the
purchaser upon any such foreclosure or sale and recognize such purchaser as the
Landlord under this Lease.

                  The provisions of this Article to the contrary
notwithstanding, and so long as Tenant is not in default hereunder, this Lease
shall remain in full force and effect for the full term hereof.




                                       18
<PAGE>   19

                  o. Name. Tenant shall not use the name of the Building or of
the development in which the Building is situated for any purpose other than as
an address of the business to be conducted by the Tenant in the Premises.

                  p. Separability. Any provision of this Lease which shall prove
to be invalid, void or illegal shall in no way affect, impair or invalidate any
other provision hereof and such other provision shall remain in full force and
effect.

                  q. Cumulative Remedies. No remedy or election hereunder shall
be deemed exclusive but shall, wherever possible, be cumulative with all other
remedies at law or in equity.

                  r. Choice of Law. This Lease shall be governed by the laws of
the State in which the Premises are located.

                  s. Signs and Auctions. Tenant shall not place any sign upon
the Premises or Building or conduct any auction thereon without Landlord's prior
written consent.

                  t. Landlord's Liability. The liabilities of the partners of
the Landlord pursuant to this Lease shall be limited to the assets of the
partnership, and Tenant, its successors and assigns hereby waive all right to
proceed against any of the partners, or the officers, shareholders, or directors
of any corporate partner of Landlord. The term "Landlord," as used in this
article, shall mean only the owner or owners at the time in question of the fee
title or an interest in a ground lease of the building. Notwithstanding anything
to the contrary contained herein, the extent of Landlord's liability under this
Lease shall be limited to the property of which the Premises herein are a part,
and Tenant shall not seek any personal liability against Landlord or any of
Landlord's partners.

         30. BROKERS. Tenant warrants that it has had no dealings with any real
estate brokers or agents in connection with the negotiation of this Lease
excepting only and it knows of no other real estate broker or agent who is
entitled to a commission in connection with this Lease, excepting only Regal
Management Company, Colorado Group, and Ebert Investment Company.

         31. LIEN OF LANDLORD. Tenant hereby grants to the Landlord a lien upon
all the furniture, fixtures, equipment, and other property belonging to the
Tenant located on or within the leased premises at any time during the Lease
term, to secure the performance of the Tenant's obligations under this Lease,
said lien to be prior to any other lien on such property except a lien in favor
of the seller of such property to secure the unpaid purchase price thereof. This
Landlord's lien may be foreclosed in the same manner as a security agreement,
and the filing of this Lease or a memorandum thereof, or a financing statement
in the security interest records of Boulder County, Colorado, shall constitute
full lawful notice of this lien. If the Landlord also has a lien on such
property, or any portion thereof, by virtue of any other instrument, or by
operation of law, the lien under this Lease shall be in addition thereto, and
the Landlord





                                       19
<PAGE>   20

shall have alternate remedies at his option. Landlord and Tenant agree that this
Lease and security agreement serves as a financing statement and that a copy or
other reproduction of this portion of this Lease may be filed of record by
Landlord and have the same force and effect as the original. This security
agreement and financing statement also covers fixtures located at the Premises
on a portion to the Land described on Exhibit A, which is owned by Landlord.
Notwithstanding anything to the contrary in this Lease, Landlord agrees to
subordinate any lien in its favor under this paragraph to any security interest
or lien now existing or hereafter created in favor of any lender that has loaned
or will loan money to Tenant for the acquisition of assets used in the Premises
or for working capital for Tenant's operations in the Premises. Landlord agrees
to execute documentation reasonably acceptable to its counsel to evidence the
subordination of Landlord's lien rights.

         32. MISCELLANEOUS.

                  a. Roof drains have leaked allowing water to enter the lower
level of the building of which the Premises are a part. Landlord shall prior to
September 1, 1992, repair the roof drains. Thereafter the repair of roof drains
shall be a part of Tenant's maintenance responsibility.

                  b. The building needs additional heating, ventilating and air
conditioning equipment installed in the building to provide and maintain the
level of comfort required. The Tenant Improvement allowance herein provided for
shall be used to the extent necessary to purchase and install sufficient
equipment to provide and maintain the desired comfort level.

                  c. Landlord has retained an electrical engineer to plan and
design a parking lot lighting system to replace the existing system. Landlord
shall, prior to September 1, 1992, install and pay for the revised lighting
system in accordance with said plans.

                  d. Landlord has filed with the City of Boulder a request that
the City permit Landlord to construct a new parking lot, with 23 additional
parking places, at the east end of the building. Landlord agrees to diligently
pursue the request and, if granted, to construct the new parking lot and
re-landscape the area surrounding the parking lot, at its expense, within 90
days after the request is granted. It is also agreed that Landlord and Tenant
will coordinate the construction of the parking lot and Tenant improvements so
that Tenant will be able to install conduit or other improvements under the new
parking lot in the most cost effective manner.

                  e. Landlord shall seal, repair and restripe, at its expense,
the parking lot prior to September 30, 1992, unless Tenant requests a delay for
any reason.

                  f. So long as Tenant properly maintains and repairs the
heating, ventilating and air conditioning equipment, either existing or
installed by Landlord or Tenant after the date of this Lease, Tenant shall have
primary responsibility for such maintenance and repair; provided, however,
Tenant shall maintain records of the






                                       20
<PAGE>   21

maintenance and repair which records shall be made available to Landlord upon
request. Landlord presently contracts with Control Service Center, Inc. to
maintain and repair the heating, ventilating and air conditioning equipment and
would prefer to have Control Service Center maintain such equipment for the
Property. Landlord recognizes that it is in the best interest of Tenant to
contract for such maintenance with the company of its choosing, but agrees to
allow Control Service Center to bid for such service during the term of this
Lease and shall consider using Control Service Center to maintain and repair
said equipment.

                  g. Landlord shall provide Tenant a Tenant Finish Allowance
("TFA"), not to exceed $12.00 per square foot for 122,546 square feet of the
demised premises, or $1,470,552.00. The basic rental provided for in Paragraph 5
hereof includes amortization of the TFA based upon a loan interest rate of
9.75%, coverage rate of 1.25, a twelve year term (or an increase in the basic
rental $5.30 per square foot by $2.1252 per square foot for the entire 122,546
square feet). If, during the term of this lease, the interest rate charged by
Landlord's lender or lenders increases or decreases, the unamortized portion of
the TFA shall be reamortized over the remaining term of this Lease using the new
interest rate or rates times the coverage rate of 1.25 and the basic rental
shall be adjusted to reflect the change in the interest rate being paid by
Landlord as of the date of change. Tenant finish constructed under the
provisions Paragraph 32.g. and 32.h. shall be substantially in accordance with
the preliminary design prepared by Tenant and approved by Landlord on or before
July 31, 1992 and when signed by both Landlord and Tenant shall be considered
Exhibit D to this Lease.

                  h. Tenant agrees pay for additional tenant improvements
costing not less than $980,368.00 on the same 122,546 square feet that Landlord
is providing a Tenant Finish Allowance of $1,470,552. If Tenant does not expend
said amount on or before June 30, 1993, Landlord's Tenant Finish Allowance shall
be reduced pro rata. For example, if Tenant pays $7.00 per square foot for
tenant finish (a reduction of 12.5%) Landlord's TFA shall be reduced by $1.50
per square foot (12.5% of $12.00). Tenant shall pay for all tenant improvements
in the first instance and shall notify Landlord, in writing, when $1,470,552.00
of improvements have been completed. Landlord shall reimburse Tenant
$1,470,552.00 within one hundred and twenty (120 days) after receipt of said
written notice, but in no event later than October 1, 1992. Tenant shall spend
not less than $1,470,552.00 for improvements to the property prior to October 1,
1992 and shall on or prior to October 1, 1992, sign and deliver the Estoppel
Statement attached hereto as Exhibit "C" to Landlord.

                  i. Landlord agrees to pay for a new Carlyle EPDM roof system
to be installed on the entire roof at an estimated cost of $158,744.00. Landlord
and Tenant agree that they shall coordinate the roof installation and the tenant
finish to avoid unnecessary delays and additional costs. Tenant agrees to pay
Landlord, as additional operating expenses, the amortized cost of the roof
system over the term of this lease remaining after installation of the roof is
complete. The roof cost, including the cost of a fifteen year guarantee, shall
be amortized at 10% per annum over a term of fifteen years.





                                       21

                  k. Any Tenant improvements will be designed to the Tenant's
specifications and Tenant shall contract with a general contractor in accordance
with the provisions of Paragraph 10 hereof to complete same. The cost estimate
for the Tenant finish improvements will be reviewed and approved by both parties
prior to construction.

                  l. If for any reason, after the Tenant has commenced
construction of these improvements, if Tenant should terminate, abandon, or
cause possession of the demised Premises to be terminated prior to the end of
the initial Lease Term, or if the Tenant should fail to occupy the demised
Premises immediately upon completion of the improvements, it is acknowledged
that, in addition to any other natural responsibilities or liabilities the
Tenant might have to the Landlord for damages, the Tenant and/or its guarantor
shall be obligated to immediately reimburse the Landlord for any and all costs
incurred by the Landlord in providing these improvements.

                  m. Landlord agrees that Tenant shall have a right-of-first
refusal to purchase Premises on the same terms and conditions contained in a
bona fide offer received by Landlord from a third party. Tenant shall have five
(5) days after receipt of written notice from Landlord that Landlord has
received an offer, within which to deliver to Landlord written notice of its
intent to exercise this right-of-first refusal. If Tenant fails to exercise this
right-of-first refusal as provided, the right shall terminate forthwith.

                  n. At anytime Landlord's consent is required herein, such
consent shall not be unreasonably withheld.

                  o. Landlord hereby consents to Tenant's construction of
additional parking on that portion of Lot 1 lying east of Exposition Drive
provided, however, Tenant shall obtain the required modifications to the PUD and
building permits to do so; provided further, however, any such construction
shall be paid for by Tenant and said construction shall be completed pursuant to
the provisions of Paragraph 10 of this Lease.

                  p. Notwithstanding the provisions of Paragraph 5(a) hereof,
basic rental for the month of January 1994 shall be reduced by $54,125.00.

         The parties hereto have executed this Lease at the place and on the
dates specified immediately adjacent to their respective signatures.

         If this Lease has been filled in, it has been prepared for submission
to Tenant's attorney for its approval. No representation or recommendation is
made by the real estate broker or its agents or employees as to the legal
sufficiency, legal effect, or tax consequences of this Lease, or the
transactions relating thereto.
