such non-compliance, take such action, at Lessor's expense, as may be reasonable

circumstances shall the right herein granted to use the Common Areas to be
deemed to include the right to store any property, temporarily or permanently,

written consent of Lessor or Lessor's designated agent, which consent may be
revoked at any time. In the event that any unauthorized storage shall occur then

3. TERM.

           3.1 TERM. The Commencement Date, Expiration Date and Original Term of
this Lease are as specified in Paragraph 1.3.

           3.2 EARLY POSSESSION. If an Early Possession Date is specified in
Paragraph 1.4 and if Lessee totally or partially occupies the Premises after the
Early Possession Date but prior to the Commencement Date, the obligation to pay
Base Rent shall be abated for the period of such early occupancy. All other
terms of this Lease, however, (including but no limited to the obligations to
pay Lessee's Share of Common Area Operating Expenses and to carry the insurance
required by Paragraph 8) shall be in effect during such period. Any such early
possession shall not affect nor advance the Expiration Date of the Original
Term.

           3.3 DELAY IN POSSESSION. If for any reason Lessor cannot deliver
possession of the Premises to Lessee by the Early Possession Date, if one is
specified in Paragraph 1.4, or if no Early Possession Date is specified, by the
Commencement Date, Lessor shall not be subject to any liability therefore, nor
shall such failure affect the validity of this Lease, or the obligations of
Lessee hereunder, or extend the term hereof, but in such case, Lessee shall not,
except as otherwise provided herein, be obligated to pay rent or perform any
other obligation of Lessee under the terms of this Lease until Lessor delivers
possession of the Premises to Lessee. If possession of the Premises is not
delivered to Lessee within sixty (60) days after the Commencement Date, Lessee
may, at its option, by notice in writing to Lessor within ten (10) days after
the end of said sixty (60) day period, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided further,
however, that if such written notice of Lessee is not received by Lessor with
said ten (10) day period, Lessee's right to cancel this Lease hereunder shall
terminate and be of no further force or effect. Except as may be otherwise
provided, and regardless of when the Original Term actually commences, if
possession is not tendered to Lessee when required by this Lease and Lessee does
not terminate this Lease, as aforesaid, the period free of the obligation to pay
Base Rent, if any, that Lessee would otherwise have enjoyed shall run from the
date of delivery of possession and continue for a period equal to the period
during which the Lessee would have otherwise enjoyed under the terms hereof, but
minus any days caused by the acts, charges or omissions of Lessee.

as the same may be adjusted from time to time, to Lessor in lawful money of the
United States, without offset or deduction, on or before the day on which it is

any period during the term hereof which is for less than one full month shall be
prorated based upon the actual number of days of the month involved. Payment of
Base Rent and other charges shall be made to Lessor at its address stated herein
or to such other persons or at such other addresses as Lessor may from time to
time designate in writing to Lessee.

                               (viii) Any other services to be provided by

Taxes that are specifically attributable to the Building or to any other
building in the Industrial Center or to the operation, repair and maintenance
thereof, shall be allocated entirely to the Building or to such other building.
However, any Common Area Operating Expenses and Real Property Taxes that are not
specifically attributable to the Building or to any other building or to the
operation, repair and maintenance thereof, shall be equitably allocated by
Lessor to all buildings in the Industrial Center.

                     (c) The inclusion of the improvements, facilities and
services set forth in Subparagraph 4.2(a) shall not be deemed to impose an
obligation upon Lessor to either have said improvements or facilities or to
provide those services unless the Industrial Center already has the same, Lessor
already provides the services, or Lessor has agreed elsewhere in this Lease to
provide the same or some of them.

                     (d) Lessee's Share of Common Area Operating Expenses shall
be payable by Lessee with ten (10) days after a reasonably detailed statement of
actual expenses is presented to Lessee by Lessor. At Lessor's option, however,
an amount may be estimated by Lessor from time to time of Lessee's Share of
annual Common Area Operating Expenses and the same shall be payable monthly or
quarterly, as Lessor shall designate, during each 12-month period of the Lease
term, on the same day as the Base Rent is due hereunder. Lessor shall deliver to
Lessee with sixty (60) days after the expiration of each calendar year a
reasonably detailed statement showing Lessee's Share of the actual Common Area
Operating Expenses incurred during the preceding year. If Lessee's payments
under this Paragraph 4.2(d) during said preceding year exceed Lessee's Share as
indicated on said statement, Lessee shall be credited the amount of such over
payment against Lessee's Share of Common Area Operating Expenses next becoming
due. If Lessee's payments under this Paragraph 4.2(d) during said preceding year
were less than Lessee's Share as indicated on said statement, Lessee shall pay
to Lessor the amount of the deficiency within ten (10) days after delivery by
Lessor to Lessee of said statement.

5. SECURITY DEPOSIT. Lessee shall deposit with Lessor upon Lessee's execution
hereof the Security Deposit set forth in Paragraph 1.7 as security for Lessee's
faithful performance of Lessee's obligations under this Lease. If Lessee fails
to pay Base Rent or other rent or charges due hereunder, or otherwise Defaults
under this Lease (as defined in Paragraph 13.1), Lessor may use, apply or retain
all or any portion of said Security Deposit for the payment 



                                      -5-
<PAGE>   6

of any amount due Lessor or to reimburse or compensate Lessor for any liability,
cost expense, loss or damage (including attorneys' fees) which Lessor may suffer
or incur by reason thereof. If Lessor uses or applies all or any portion of said
Security Deposit, Lessee shall with ten (10) days after written request
therefore deposit monies with Lessor sufficient to restore said Security Deposit
to the full amount required by this Lease. Lessor shall not be required to keep
all or any part of the Security Deposit separate from its general accounts.
Lessor shall, at the expiration or earlier termination of the term hereof and
after Lessee has vacated the Premises, return to Lessee (or, at Lessor's option,
to the last assignee, if any, of Lessee's interest herein), that portion of the
Security Deposit not used or applied by Lessor. Unless otherwise expressly
agreed in writing by Lessor , no part of the Security Deposit shall be
considered to be held in trust, to bear interest or other increment for its use,
or to be prepayment for any monies to be paid by Lessee under this Lease. (See
Addendum, Paragraph #52)

6.         USE.

           6.1       PERMITTED USE.

                     (a) Lessee shall use and occupy the Premises only for the 
Permitted Use set forth in Paragraph 1.8, or any other legal use which is
reasonably comparable thereto, and for no other purpose. Lessee shall not use or
permit the use of the Premises in a manner that is unlawful, creates waste or a
nuisance, or that disturbs owners and/or occupants of, or causes damage to the
Premises or neighboring premises or properties.

                     (b) Lessor hereby agrees to not unreasonably withhold or
delay its consent to any written request by Lessee, Lessee's assignees or
subtenants, and by prospective assignees and subtenants or Lessee, its assignees
and subtenants, for a modification of said Permitted Use, so long as the same
will not impair the structural integrity of the improvements on the Premises or
in the Building or the mechanical or electrical systems therein, does not
conflict with uses by other lessees, is not significantly more burdensome to the
Premises or the Building and the improvements thereon, and is otherwise
permissible pursuant to this Paragraph 6. If Lessor elects to withhold such
consent, Lessor shall with five (5) business days after such request give a
written notification of same, which notice shall include an explanation of
Lessor's reasonable objections to the change in use.

           6.2       HAZARDOUS SUBSTANCES.

                     (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS 
SUBSTANCE" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of
existence, use, manufacture, disposal, transportation, spill, release or effect,
either by itself or in combination with other materials expected to be on the
Premises, is either: (i ) potentially injurious to the public health, safety or
welfare, the environment, or the Premises; (ii) regulated or monitored by any
governmental authority; or (iii) a basis for potential liability of Lessor to
any governmental agency or third party under any applicable statute or common
law theory. Hazardous Substance shall include, but not be limited to,
hydrocarbons, petroleum, gasoline, crude oil or any products or by-products
thereof. Lessee shall not engage in any activity in or about the Premises which
constitutes a Reportable Use (as hereinafter defined) of Hazardous Substances
without the express prior written consent of Lessor and compliance in a timely
manner (at Lessee's sole cost and expense) with all Applicable Requirements (as
defined in Paragraph 6.3). "REPORTABLE USE" shall mean (i) the installation or
use of any above or below ground storage tank, (ii) the generation, possession,
storage, use, transportation, or disposal of a Hazardous Substance that requires
a permit from, or with respect to which a report, notice, registration or
business plan is required to be filed with, any governmental authority, and
(iii) the presence in, on or about the Premises of a Hazardous Substance with
respect to which any Applicable Laws require that a notice be given to persons
entering or occupying the Premises or neighboring properties. Notwithstanding
the foregoing, Lessee may, without Lessor's prior consent, but upon notice to
Lessor and in compliance with all Applicable Requirements, use any ordinary and
customary materials reasonably required to be used by Lessee in the normal
course of the Permitted Use, so long as such use is not a Reportable Use and
does not expose the Premises or neighboring properties to any meaningful risk of
contamination or damage or expose Lessor to any liability therefor. In addition,
Lessor may (but without any obligation to do so) condition its consent to any
Reportable Use of any Hazardous Substance by Lessee upon Lessee's giving Lessor
such additional assurances as Lessor, in its reasonable discretion, deems
necessary to protect itself, the public, the Premises and the environment
against damage, contamination or injury and/or liability therefor, including but
not limited to the installation (and, at Lessor's option, removal on or before
Lease expiration or earlier termination) 



                                      -6-
<PAGE>   7

of reasonably necessary protective modifications to the Premises (such as
concrete encasements) and/or the deposit of an additional Security Deposit under
Paragraph 5 hereof.

                     (b) DUTY TO INFORM LESSOR. If Lessee knows, or has
reasonable cause to believe, that a Hazardous Substance has come to be located
in, on, under or about the Premises or the Building, other than as previously
consented to by Lessor, Lessee shall immediately give Lessor written notice
thereof, together with a copy of any statement, report, notice, registration,
application, permit, business plan, license, claim, action, or proceeding given
to, or received from any governmental authority or private party concerning the
presence, spill, release, discharge of, or exposure to, such Hazardous Substance
including but not limited to all such documents as may be involved in any
Reportable Use involving the Premises. Lessee shall not cause or permit any
Hazardous Substance to be spilled or released in, on, under or about the
Premises (including, without limitation, through the plumbing or sanitary sewer
system).

                     (c) INDEMNIFICATION. Lessee shall indemnify, protect,
defend and hold Lessor, its agents, employees, lenders and ground lessor, if
any, and the Premises, harmless from and against any and all damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, loss of
permits and attorneys' and consultants' fees arising out of or involving any
Hazardous Substance brought onto the Premises by or for Lessee or by anyone
under Lessee's control. Lessee's obligation under this Paragraph 6.2(c) shall
include, but not be limited to, the effects of any contamination or injury to
person, property or the environment created or suffered by Lessee, and the cost
of investigation (including consultants' and attorneys' fees and testing),
removal, remediation, restoration and/or abatement thereof, or of any
contamination therein involved, and shall survive the expiration or earlier
termination of this Lease. No termination, cancellation or release agreement
entered into by Lessor and Lessee shall release Lessee from its obligations
under this Lease with respect to Hazardous Substances, unless specifically so
agreed by Lessor in writing at the time of such agreement.

           6.3 LESSEE'S COMPLIANCE WITH REQUIREMENTS. Lessee shall, at Lessee's
sole cost and expense, fully, diligently and in a timely manner comply with all
"APPLICABLE REQUIREMENTS," which term is used in this Lease to mean all laws,
rules, regulations, ordinances, directives, covenants, easements and
restrictions of record, permits, the requirements of any applicable fire
insurance underwriter or rating bureau, and the recommendations of Lessor's
engineers and/or consultants, relating in any manner to the Premises (including
but not limited to matters pertaining to (i) industrial hygiene, (ii)
environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions, and (iii) the use, generation, manufacture, production,
installation, maintenance, removal, transportation, storage, spill, or release
of any Hazardous Substance), now in effect or which may hereafter come into
effect. Lessee shall, within five (5) days after receipt of Lessor's written
request, provide Lessor with copies of all documents and information, including
but not limited to permits, registrations, manifests, applications, reports and
certificates, evidencing Lessee's compliance with any Applicable Requirements
specified by Lessor, and shall immediately upon receipt, notify Lessor in
writing (with copies of any documents involved) of any threatened or actual
claim, notice, citation, warning, complaint or report pertaining to or involving
failure by Lessee or the Premises to comply with any Applicable Requirements.

           6.4 INSPECTION; COMPLIANCE WITH LAW. Lessor, Lessor's agents,
employees, contractors and designated representatives, and the holders of any
mortgages, deeds of trust or ground leases on the Premises ("LENDERS") shall
have the right to enter the Premises at any time in the case of an emergency,
and otherwise at reasonable times, for the purpose of inspecting the condition
of the Premises and for verifying compliance by Lessee with this Lease and all
Applicable Requirements (as defined in Paragraph 6.3), and Lessor shall be
entitled to employ experts and/or consultants in connection therewith to advise
Lessor with respect to Lessee's activities, including but not limited to
Lessee's installation, operation, use, monitoring, maintenance, or removal of
any Hazardous Substance on or from the Premises. The costs and expenses of any
such inspections shall be paid by the party requesting same, unless a Default or
Breach of this Lease by Lessee or a violation of Applicable Requirements or a
contamination, caused or materially contributed to by Lessee, is found to exist
or to be imminent, or unless the inspection is requested or ordered by a
governmental authority as the result of any such existing or imminent violation
or contamination. In such case, Lessee shall upon request reimburse Lessor or
Lessor's Lender, as the case may be, for the costs and expenses of such
inspections. Lessee shall not be responsible for any costs as a result of
recommendations of Lessor's engineers or consultants which would be in excess of
those required by government agencies and/or insurance underwriters and/or any
other third party which establishes Applicable Requirements.

7. MAINTENANCE, REPAIRS, UTILITY INSTALLATIONS, TRADE FIXTURES AND ALTERATIONS.

           7.1 LESSEE'S OBLIGATIONS.

Obligations, 9 (Damage or Destruction), and 14 (Condemnation), Lessee shall, at
Lessee's sole cost and expense and at all times, keep the Premises and every
part thereof in good order, condition and repair (whether or not such portion of
the Premises requiring repair, or the means of repairing the same, are
reasonably or readily accessible to Lessee, and whether or not the need for such
repairs occurs as a result of Lessee's use, any prior use, the elements or the
age of such portion of the Premises), including, without limiting the generality
of the foregoing, all equipment or facilities specifically serving the Premises,
such as plumbing, heating, air conditioning, ventilating, electrical, lighting
facilities, boilers, fired or unfired pressure vessels, fire hose connections if
within the Premises, fixtures, interior walls, interior surfaces of exterior
walls, ceilings, floors, windows, doors, plate glass, and skylights, but
excluding any items which are the responsibility of Lessor pursuant to Paragraph
7.2 below. Lessee, in keeping the Premises in good order, condition and repair,
shall exercise and perform good maintenance practices. Lessee's obligations
shall include restorations, replacements of renewals when necessary to keep the
Premises and all improvements thereon or a part thereof in good order, condition
and state of repair.

           (b)       N/A

           (c) If Lessee fails to perform Lessee's obligations under this
Paragraph 7.1, Lessor may enter upon the Premises after ten (10) days' prior
written notice to Lessee (except in the case of an emergency, in which case no
notice shall be required), perform such obligations on Lessee's behalf, and put
the Premises in good order, condition and repair; in accordance with Paragraph
13.2 below.

           7.2 LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 2.2
(Condition), 2.3 (Compliance with Covenants, Restrictions and Building Code),
4.2 (Common Area Operating Expenses), 6 (Use), 7.1 (Lessee's Obligations), 9

walkways, parkways, driveways, landscaping, fences, signs and utility systems
serving the Common Areas and all parts thereof, as well as proving the services
for which there is a Common Area Operating Expense pursuant to Paragraph 4.2.
Lessor shall not be obligated to paint the exterior or interior surfaces of
exterior walls nor shall Lessor be obligated to maintain, repair or replace
windows, doors or plate glass of the Premises. Lessee expressly waives the
benefit of any statute now or hereafter in effect which would otherwise afford
Lessee the right to make repairs at Lessor's expense or to terminate this Lease
because of Lessor's failure to keep the Building, Industrial Center or Common
Areas in good order, condition and repair.

           7.3       UTILITY INSTALLATIONS, TRADE FIXTURES, ALTERATIONS.

                     (a) DEFINITIONS: CONSENT REQUIRED. The term "UTILITY
INSTALLATIONS" is used in this Lease to refer to all air lines, power panels,
electrical distribution, security, fire protection systems, communications
systems, lighting fixtures, heating, ventilating and air conditioning equipment,
plumbing, and fencing in, on or about the Premises. The term "TRADE FIXTURES"
shall mean Lessee's machinery and equipment which can be removed without doing
material damage to the Premises. The term "ALTERATIONS" shall mean any
modification of the improvements on the Premises which are provided by Lessor
under the terms of this Lease, other than Utility Installations or Trade
Fixtures. "LESSEE-OWNED ALTERATIONS AND/OR UTILITY INSTALLATIONS" are defined as
Alterations and/or Utility Installations made by Lessee that are not yet owned
by Lessor pursuant to Paragraph 7.4(a). Lessee shall not make or cause to be
made any Alterations or Utility Installations in, on, under or about the
Premises without Lessor's prior written consent. Lessee may, however, make
non-structural Utility Installations to the interior of the Premises (excluding
the roof) without Lessor's consent but upon notice to Lessor, so long as they
are not visible from the outside of the Premises, do not involve puncturing,
relocating or removing the roof or any existing walls, or changing or
interfering with the fire sprinkler or fire detection systems and the cumulative
cost thereof during the term of this Lease as extended does not exceed
$2,500.00.



                                      -8-
<PAGE>   9
                     (b) CONSENT. Any Alterations or Utility Installations that
Lessee shall desire to make and which require
the consent of the Lessor shall be presented to Lessor in written form with
detailed plans. All consents given by Lessor, whether by virtue of Paragraph
7.3(a) or by subsequent specific consent, shall be deemed conditioned upon: (i)
Lessee's acquiring all applicable permits required by governmental authorities;
(ii) the furnishing of copies of such permits together with a copy of the plans
and specifications for the Alteration or Utility Installation to Lessor prior to
commencement of the work thereon; and (iii) the compliance by Lessee with all
conditions of said permits in a prompt and expeditious manner. Any Alterations
or Utility Installations by Lessee during the term of this Lease shall be done
in a good workmanlike manner, with good and sufficient materials, and be in
compliance with all Applicable Requirements. Lessee shall promptly upon
completion thereof furnish Lessor with as-built plans and specifications
therefor. Lessor may, (but without obligation to do so) condition its consent to
any requested Alteration or Utility Installation that costs $2,500.00 or more
upon Lessee's providing Lessor with a lien and completion bond in an amount
equal to one and one-half times the estimated cost of such Alteration or Utility
Installation.

                     (c) LIEN PROTECTION. Lessee shall pay when due all claims
for labor or materials furnished or alleged to have been furnished to or for
Lessee at or for use on the Premises, which claims are or may be secured by any
mechanic's or materialmen's lien against the Premises or any interest therein.
Lessee shall give Lessor not less than ten (10) days' notice prior to the
commencement of any work in, on, or about the Premises, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises as
provided by law. If Lessee shall, in good faith, contest the validity of any
such lien, claim or demand, then Lessee shall, at its sole expense, defend and
protect itself, Lessor and the Premises against the same and shall pay and
satisfy any such adverse judgment that may be rendered thereon before the
enforcement thereof against the Lessor or the Premises. If Lessor shall require,
Lessee shall furnish to Lessor a surety bond satisfactory to Lessor in an amount
equal to one and one-half times the amount of such contested lien claim or
demand, indemnifying Lessor against liability for the same, as required by law
for the holding of the Premises free from the effect of such lien or claim. In
addition, Lessor may require Lessee to pay Lessor's reasonable attorneys fees
and costs in participating in such action if Lessor shall decide it is to its
best interest to do so.

           7.4 OWNERSHIP, REMOVAL, SURRENDER, AND RESTORATION.

           (a) OWNERSHIP. Subject to Lessor's right to require their removal and
to cause Lessee to become the owner thereof as hereinafter provided in this
Paragraph 7.4, all Alterations and Utility Installations made to the Premises by
Lessee shall be the property of and owned by Lessee, but considered a part of
the Premises. Lessor may, at any time and at its option, elect in writing to
Lessee to be the owner of all or any specified part of the Lessee-Owned
Alterations and Utility Installations. Unless otherwise instructed per
Subparagraph 7.4(b) hereof, all Lessee-Owned Alterations and Utility
Installations shall, at the expiration or earlier termination of this Lease,
become the property of Lessor and remain upon the Premises and be surrendered
with the Premises by Lessee.

           (b) REMOVAL. Unless otherwise agreed in writing, Lessor may require
that any or all Lessee-Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding that their
installation may have been consented to by Lessor. Lessor may require the
removal at any time or all or any part of any Alterations or Utility
Installations made without the required consent of Lessor.

           (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by the
end of the last day of the Lease term or any earlier termination date, clean and
free of debris and in good operating order, condition and state of repair,
ordinary wear and tear excepted. Ordinary wear and tear shall not include any
damage or deterioration that would have been prevented by good maintenance
practice or by Lessee performing all of its obligations under this Lease. Except
as otherwise agreed or specified herein, the Premises, as surrendered, shall
include the Alterations and Utility Installations. The obligation of Lessee
shall include the repair of any damage occasioned by the installation,
maintenance or removal of Lessee's Trade Fixtures, furnishings, equipment, and
Lessee-Owned Alterations and Utility Installations, as well as the removal of
any storage tank installed by or for Lessee, and the removal, replacement, or
remediation of any soil, material or ground water contaminated by Lessee, all as
may then be required by Applicable Requirements and/or good practice. Lessee's
Trade Fixtures shall remain the property of Lessee and shall be removed by
Lessee subject to its obligation to repair and restore the Premises per this
Lease.

           (8.1) PAYMENT OF PREMIUMS. The cost of the premiums for the insurance
policies maintained by Lessor under this Paragraph 8 shall be a Common Area
Operating Expense pursuant to Paragraph 4.2 hereof. Premiums for policy periods
commencing prior to, or extending beyond, the term of this Lease shall be
prorated to coincide with the corresponding Commencement Date or Expiration
Date.

           (8.2) LIABILITY INSURANCE

                     (a) CARRIED BY LESSEE. Lessee shall obtain and keep in
force during the term of this Lease a Commercial General Liability policy of
insurance protecting Lessee, Lessor and any Lender(s) whose names have been
provided to Lessee in writing (as additional insured) against claims for bodily
injury, personal injury and property damage based upon, involving or arising out
of the ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto. Such insurance shall be on a occurrence basis providing
single limit coverage in an amount not less than $1,000,000 per occurrence with
an "Additional Insured-Managers or Lessors of Premises" endorsement and contain
the "Amendment of the Pollution Exclusion" endorsement for damage caused by
Heat, smoke or fumes from a hostile fire. The policy shall not contain any
intra-insured exclusions as between insured persons or organizations, but shall
include coverage for liability assumed under this Lease as an "INSURED CONTRACT"
for the performance of Lessee's indemnity obligations under this Lease. The
limits of said insurance required by this Lease or as carried by Lessee shall
not, however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder. All insurance to be carried by Lessee shall be primary to and not
contributory with any similar insurance carried by Lessor, whose insurance shall
be considered excess insurance only.

                     (b) CARRIED BY LESSOR. Lessor shall also maintain liability
insurance described in Paragraph 8.2(a) above, in addition to and not in lieu
of, the insurance required to be maintained by Lessee. Lessee shall not be named
as an additional insured therein.

           (8.3) PROPERTY INSURANCE-BUILDING, IMPROVEMENTS AND RENTAL VALUE.

                     (a) BUILDING AND IMPROVEMENTS. Lessor shall obtain and keep
in force during the term of this Lease a policy or policies in the name of
Lessor, with loss payable to Lessor and to any Lender(s), insuring against loss
or damage to the Premises. Such insurance shall be for full replacement cost, as
the same shall exist from time to time, or the amount required by any
Lenders(s), but in no event more than the commercially reasonable and available
insurable value thereof if, by reason of the unique nature or age of the
improvements involved, such latter amount is less than full replacement cost.
Lessee-Owned Alterations and Utility Installations, Trade Fixtures and Lessee's
personal property shall be insured by Lessee pursuant to Paragraph 8.4. If the
coverage is available and commercially appropriate, Lessor's policy or policies
shall insure against all risks of direct physical loss or damage (except the
perils of flood and/or earthquake unless required by a Lender), including
coverage for any additional costs resulting from debris removal and reasonable
amounts of coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Building required
to be demolished or removed by reason of the enforcement or any building,
zoning, safety or land use laws as the result of a covered loss, but not
including plate glass insurance. Said policy or policies shall also contain an
agreed valuation provision in lieu of any co-insurance clause, waiver of
subrogation, and inflation guard protection causing an increase in the annual
property insurance coverage amount by a factor of not less than the adjusted
U.S. Department of Labor Consumer Price Index for All Urban Consumers for the
city nearest to where the Premises are located.

                     (b) RENTAL VALUE. Lessor shall also obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and any Lender(s) insuring the loss of the full
rental and other charges payable by all lessees of the Building to Lessor for
one year (including all Real Property Taxes, insurance costs, all Common Area
Operating Expenses and any scheduled rental increases). Said insurance may
provide that in the event the Lease is terminated by reason of an insured loss,
the period of indemnity for such coverage shall be extended beyond the date of
the completion of repairs or replacement of the Premises, to provide for one
full year's loss of rental revenues from the date of any such loss. Said
insurance shall contain an agreed valuation provision in lieu of any
co-insurance clause, and the amount of coverage shall be adjusted annually to
reflect the projected rental income, Real Property Taxes, insurance premium
costs and other expenses, if any, otherwise payable, 



                                      -10-
<PAGE>   11

for the next 12 month period. Common Area Operating Expenses shall include any
deductible amount in the event of such loss.

                     (c) ADJACENT PREMISES. Lessee shall pay for any increase in
the premiums for the property insurance of the Building and for the Common Areas
or other buildings in the Industrial Center if said increase is caused by
Lessee's acts, omissions, use or occupancy of the Premises.

                     (d) LESSEE'S IMPROVEMENTS. Since Lessor is the Insuring
Party, Lessor shall not be required to insure Lessee-Owned Alterations and
Utility Installations unless the item in question has become the property of
Lessor under the terms of this Lease.

           8.4 LESSEE'S PROPERTY INSURANCE. Subject to the requirements of
Paragraph 8.5, Lessee at its cost shall either by separate policy or, at
Lessor's option, by endorsement to a policy already carried, maintain insurance
coverage on all of Lessee's personal property. Trade Fixtures and Lessee-Owned
Alterations and Utility Installations in, on, or about the Premises, similar in
coverage to that carried by Lessor as the insuring Party under Paragraph 8.3(a).
Such insurance shall be full replacement cost coverage with a deductible not to
exceed $1,000 per occurrence. The proceeds from any such insurance shall be used
by Lessee for the replacement of personal property and the restoration of Trade
Fixtures and Lessee-Owned Alterations and Utility Installations. Upon request
from Lessor, Lessee shall provide Lessor with written evidence that such
insurance is in force.

           8.5 INSURANCE POLICIES. Insurance required hereunder shall be in
companies duly licensed to transact business in the state where the Premises are
located, and maintaining during the policy term a "General Policyholders Rating"
of at least B+, V, or such other rating as may be required by a Lender, as set
forth in the most current issue of "Best's Insurance Guide." Lessee shall not do
or permit to be done anything which shall invalidate the insurance policies
referred to in this Paragraph 8. Lessee shall cause to be delivered to Lessor,
within seven (7) days after the earlier of the Early Possession Date or the
Commencement Date, certified copies of, or certificates evidencing the existence
and amounts of, the insurance required under Paragraph 8.2(a) and 8.4. No such
policy shall be cancelable or subject to modification except after thirty (30)
days' prior written notice to Lessor. Lessee shall at least thirty (30) days
prior to the expiration of such policies, furnish Lessor with evidence of
renewals or "insurance binders" evidencing renewal thereof, or Lessor may order
such insurance and charge the cost thereof to Lessee, which amount shall be
payable by Lessee to Lessor upon demand.

           8.6 WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages (whether in contract or in tort) against
the other, for loss of damage to their property arising out of or incident to
the perils required to be insured against under Paragraph 8,. The effect of such
releases and waivers of the right to recover damages shall not be limited by the
amount of insurance carried or required, or by any deductibles applicable
thereto. Lessor and Lessee agree to have their respective insurance companies
issuing property damage insurance waive any right to subrogation that such
companies may have against Lessor to Lessee, as the case may be, so long as the
insurance is not invalidated thereby.

           8.7 INDEMNITY.Except for Lessor's negligence and/or breach of express
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, loss of permits, attorneys' and consultants'
fees, expenses and/or liabilities arising out of, involving, or in connection
with, the occupancy of the Premises by Lessee, the conduct of Lessee's business,
any act, omission or neglect of Lessee, its agents, contractors, employees or
invitees, and out of any Default or Breach by Lessee in the performance in a
timely manner of any obligation on Lessee's part to be performed under this
Lease. The foregoing shall include, but not be limited to, the defense or
pursuit of any claim or any action or proceeding involved therein, and whether
or not (in the case of claims made against Lessor) litigated and/or reduced to
judgment. In case any action or proceeding be brought against Lessor by reason
of any of the foregoing matters. Lessee upon notice from Lessor shall defend the
same at Lessee's expense by counsel reasonably satisfactory to Lessor and the
Lessor shall cooperate with Lessee in such defense. Lessor need not have first
paid any such claim in order to be so indemnified.

           8.8 EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable
for injury or damage to the person or goods, wares, merchandise or other
property of Lessee, Lessee's employees, contractors, invitees, customers, or any



                                      -11-
<PAGE>   12

other person in or about the Premises, whether such damage or injury is caused
by or results from fire, steam, electricity, gas, water or rain, or from the
breakage, leakage, obstruction or other defects of pipes, fire sprinklers,
wires, appliances, plumbing, air conditioning or lighting fixtures, or from any
other cause, whether said injury or damage results from conditions arising upon
the Premises or upon other portions of the Building of which the Premises are a
part, from other sources or places, and regardless of whether the cause of such
damage or injury or the means of repairing the same is accessible or not. Lessor
shall not be liable for any damages arising from any act or neglect of any other
lessee of Lessor nor from the failure by Lessor to enforce the provisions of any
other lease in the Industrial Center. Notwithstanding Lessor's negligence or
breach of this Lease, Lessor shall under no circumstances be liable for injury
to Lessee's business or for any loss of income or profit therefrom.

9. DAMAGE OR DESTRUCTION.

           9.1 DEFINITIONS.

                     (a) "PREMISES PARTIAL DAMAGE" shall mean damage or
destruction to the Premises, other than Lessee-Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is less that fifty
percent (50%) of the then Replacement Cost (as defined in Paragraph 9.1(d) of
the Premises (excluding Lessee-Owned Alterations and Utility Installations and
Trade Fixtures) immediately prior to such damage or destruction.

                     (b) "PREMISES TOTAL DESTRUCTION" shall mean damage or
destruction to the Premises, other than Lessee-Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is fifty percent
(50%) or more of the then Replacement Cost of the Premises (excluding Lessee
-Owned Alterations and Utility Installations and Trade Fixtures) immediately
prior to such damage or destruction. In addition, damage or destruction to the
Building, other than Lessee-Owned Alterations and Utility Installations and
Trade Fixtures of any lessees of the Building, the cost of which damage or
destruction is fifty percent (50%) or more of the then Replacement Cost
(excluding Lessee-Owned Alterations and Utility Installations and Trade Fixtures
of any lessees of the Building) off the Building shall, at the option of Lessor,
be deemed to be Premises Total Destruction.

                     (c) "INSURED LOSS" shall mean damage or destruction to the
Premises, other than Lessee-Owned Alterations and Utility Installations and
Trade Fixtures, which was caused by an event required to be covered by the
insurance described in Paragraph 8.3(a) irrespective of any deductible amounts
or coverage limits involved.

                     (d) "REPLACEMENT COST" shall mean the cost to repair or
rebuild the improvements owned by Lessor at the time of the occurrence to their
condition existing immediately prior thereto, including demolition, debris
removal and upgrading required by the operation of applicable building codes,
ordinances or laws, and without deduction for depreciation.

                     (e) "HAZARDOUS SUBSTANCE CONDITION" shall mean the
occurrence or discovery of a condition involving the presence of, or a
contamination by, a Hazardous Substance as defined in Paragraph 6.2(a) in, on,
or under the Premises.

           9.2 PREMISES PARTIAL DAMAGE -- INSURED LOSS. If Premises Partial
Damage that is an Insured Loss occurs, then Lessor shall, at Lessor's expense,
repair such damage (but no Lessee's Trade Fixtures or Lessee-Owned Alterations
and Utility Installations) as soon as reasonably possible and this Lease shall
continue in full force and effect. In the event, however, that there is a
shortage of insurance proceeds and such shortage is due to the fact that, by
reason of the unique nature of the improvements in the Premises, full
replacement costs insurance coverage was not commercially reasonable and
available. Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,
within ten (10) days following receipt of written notice of such shortage and
request therefor. If Lessor receives said funds or adequate assurance thereof
within said ten (10) day period, Lessor shall complete them as soon as
reasonably possible and this Lease shall remain in full force and effect. If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect. If Lessor does not receive such funds of assurance within such
ten (10) day period, and if Lessor does not so elect to restore and repair, then
this Lease shall terminate sixty (60) days following the occurrence of the
damage or destruction. Unless otherwise 



                                      -12-
<PAGE>   13

agreed, Lessee shall in no event have any right to reimbursement from Lessor for
any funds contributed by Lessee to repair, any such damage or destruction.
Premises Partial Damage due to flood or earthquake shall be subject to Paragraph
9.3 rather than Paragraph 9.2, notwithstanding that there may be some insurance
coverage, but the net proceeds of any such insurance shall be made available for
the repairs if made by either Party.

           9.3 PARTIAL DAMAGE -- UNINSURED LOSS. If Premises Partial Damage that
is not an insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect), Lessor may at Lessor's
option, either (i) repair such damage as soon as reasonably possible at Lessor's
expense, in which event this Lease shall continue in full force and effect, or
(ii) give written notice to Lessee within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such damage of Lessor's desire to
terminate this Lease as of the date (60) days following the date of such notice.
In the event Lessor elects to give such notice of Lessor's intention to
terminate this Lease, Lessee shall have the right within ten (10) days after the
receipt of such notice to give written notice to Lessor of Lessee's commitment
to pay for the repair of such damage totally at Lessee's expense and without
reimbursement from Lessor. Lessee shall provide Lessor with the required funds
or satisfactory assurance thereof within thirty (30) days following such
commitment from Lessee. In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such repairs as soon as reasonably
possible after the required funds are available. If Lessee does not give such
notice and provide the funds or assurance thereof within the times specified
above, this Lease shall terminate as of the date specified in Lessor's notice of
termination.

           9.4 TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or not the damage
or destruction is an insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 9.7.

           9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6)
months of the term of this Lease there is damage for which the cost to repair
exceeds one month's Base Rent, whether or not an Insured Loss, Lessor may, at
Lessor's option, terminate this Lease effective sixty (60) days following the
date of occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by (a) exercising such option, and (b) providing Lessor with any shortage
in insurance proceeds (or adequate assurance thereof) needed to make the repairs
on or before the earlier of (i) the date which is ten (10) days after Lessee's
receipt of Lessor's written notice purporting to terminate this Lease, or (ii)
the day prior to the date upon which such option expire. If Lessee duly
exercises such option during such period and provides Lessor with funds (or
adequate assurance thereof) to cover any shortage in insurance proceeds, Lessor
shall, at Lessor's expense repair such damage as soon as reasonably possible and
this Lease shall continue in full force and effect. If Lessee fails to exercise
such option and provide such funds or assurance during such period, then this
Lease shall terminate as of the date set forth in the first sentence of this
Paragraph 9.5.

           9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES.

                     (a) In the event of (i) Premises Partial Damage or (ii)
Hazardous Substance Condition for which Lessee is not legally responsible, the
Base Rent, Common Area Operating Expenses and other charges, if any, payable by
Lessee hereunder for the period during which such damage or condition, its
repair, remediation or restoration continues, shall be abated in proportion to
the degree to which Lessee's use of the Premises is impaired, but not in excess
of proceeds from insurance required to be carried under Paragraph 8.3(b). Except
for abatement of Base Rent, Common Area Operating Expenses and other charges, if
any, as aforesaid, all other obligations of Lessee hereunder shall be performed
by Lessee, and Lessee shall have no claim against Lessor for any damage suffered
by reason of any such damage, destruction, repair, remediation or restoration.

                     (b) If Lessor shall be obligated to repair or restore the
Premises under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
ninety (90) days after such obligation shall accrue, Lessee may, at any time
prior to the commencement of such repair or restoration, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's 



                                      -13-
<PAGE>   14

election to terminate this Lease on a date not less than sixty (60) days
following the giving of such notice. If Lessee gives such notice to Lessor and
such Lenders and such repair or restoration is not commenced within thirty (30)
days after receipt of such notice, this Lease shall terminate as of the date
specified in said notice. If Lessor or a Lender commences the repair or
restoration of the Premises within thirty (30) days after the receipt of such
notice, this Lease shall continue in full force and effect. "COMMENCE" as used
in this Paragraph 9.6 shall mean either the unconditional authorization of the
preparation of the required plans, or the beginning of the actual work on the
Premises, whichever occurs first.

           9.7 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance
Condition occurs, unless Lessee is legally responsible therefor (in which case
Lessee shall make the investigation and remediation thereof required by
Applicable Requirements and this Lease shall continue in full force and effect,
but subject to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor
may at Lessor's option either (i) investigate and remediate such Hazardous
Substances Condition, if required , as soon as reasonably possible at Lessor's
expense, in which event this Lease shall continue in full force and effect, or
(ii) if the estimated cost to investigate and remediate such condition exceeds
twelve (12) times the then monthly Base Rent or $100,000 whichever is greater,
give written notice to Lessee within thirty (30) days after receipt by Lessor of
knowledge of the occurrence of such Hazardous Substance Condition of Lessor's
desire to terminate this Lease as of the date sixty (60) days following the date
of such notice. In the event Lessor elects to give such notice of Lessor's
intention to terminate this Lease, Lessee shall have the right within ten (10)
days after the receipt of such notice to give written notice to Lessor of
Lessee's commitment to pay for the excess costs of (a) investigation and
remediation of such Hazardous Substance Condition to the extend required by
Applicable Requirements, over (b) an amount equal to twelve (12) times the then
monthly Base Rent or $100,000, whichever is greater. Lessee shall provide Lessor
with the funds required of Lessee or satisfactory assurance thereof within
thirty (30) days following said commitment by Lessee. In such event this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
investigation and remediation as soon as reasonably possible after the required
funds are available. If Lessee does not give such notice and provide the
required funds or assurance thereof within the time period specified above, this
Lease shall terminate as of the date specified in Lessor's notice of
termination.

           9.8 TERMINATION -- ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to this Paragraph 9, Lessor shall return to Lessee any advance payment
made by Lessee to Lessor and so much of Lessee's Security Deposit as has not
been, or is not then required to be, used by Lessor under the terms of this
Lease.

           9.9 WAIVER OF STATUTES. Lessor and Lessee agree that the terms of
this Lease shall govern the effect of any damage to or destruction of the
Premises and the Building with respect to the termination of this Lease and
hereby waive the provisions of any present or future statute to the extent it is
inconsistent herewith.

10. REAL PROPERTY TAXES.

           10.1 PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Industrial Center, and except as
otherwise provided in Paragraph 10.3, any such amounts shall be included in the
calculation of Common Area Operating Expenses in accordance with the Provisions
of Paragraph 4.2.

           10.2 REAL PROPERTY TAX DEFINITION. As used herein, the term "REAL
PROPERTY TAXES" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Industrial Center by any
authority having the direct or indirect power to tax, including any city, state
or federal government, or any school, agricultural, sanitary, fire, street,
drainage, or other improvement district thereof, levied against any legal or
equitable interest of Lessor in the Industrial Center or any portion thereof,
Lessor's right to rent or other income therefrom, and/or Lessor's business of
leasing the Premises. The term "REAL PROPERTY TAXES" shall also include any tax,
fee, levy, assessment or charge, or any increase therein, imposed by reason of
events occurring, or changes in Applicable Law taking effect, during the term of
this Lease, including but not limited to a change in the ownership of the
Industrial Center or in the improvements thereon, the execution of this Lease,
or any modification, amendment or transfer thereof, and whether or not
contemplated by the Parties. In calculating Real Property Taxes for any calendar
year, the Real Property Taxes for any real estate tax year shall be included in
the calculation of Real Property Taxes for such calendar year based upon the
number of days which such calendar year and tax year have in common.



                                      -14-
<PAGE>   15

           10.3 ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses shall
not include Real Property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the Industrial
Center by other lessees or by Lessor for the exclusive enjoyment of such other
lessees. Notwithstanding Paragraph 10.1 hereof, Lessee shall, however, pay to
Lessor at the time Common Area Operating Expenses are payable under Paragraph
4.2, the entirety of any increase in Real Property Taxes if assessed solely by
reason of Alterations, Trade Fixtures or Utility Installations placed upon the
Premises by Lessee or at Lessee's request.

           10.4 JOINT ASSESSMENT. If the Building is not separately assessed,
Real Property Taxes allocated to the Building shall be an equitable proportion
of the Real Property Taxes for all of the land and improvements included within
the tax parcel assessed, such proportion to be determined by Lessor from the
respective valuations assigned in the assessor's work sheets or such other
information as may be reasonably available. Lessor's reasonable determination
thereof, in good faith, shall be conclusive.

           10.5 LESSEE'S PROPERTY TAXES. Lessee shall pay prior to delinquency
all taxes assessed against and levied upon Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or stored within the Industrial Center. When
possible, Lessee shall cause its Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.
If any of Lessee's said property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee's property within ten
(10) days after receipt of a written statement setting forth the taxes
applicable to Lessee's property.

11. UTILITIES. Lessee shall pay directly for all utilities and services supplied
to the Premises, including but not limited to electricity, telephone, security,
gas and cleaning of the Premises, together with any taxes thereon. If any such
utilities or services are not separately metered to the Premises or separately
billed to the Premises, Lessee shall pay to Lessor a reasonable proportion to be
determined by Lessor of all such charges jointly metered or billed with other
premises in the Building, in the manner and within the time periods set forth in
Paragraph 4.2(d).

12. ASSIGNMENT OF SUBLETTING.

           12.1 LESSOR'S CONSENT REQUIRED.

                     (a) Lessee shall not voluntarily or by operation of law
assign, transfer, mortgage or otherwise transfer or encumber (collectively,
"assign") or sublet all or any part of Lessee's interest in this Lease or in the
Premises without Lessor's prior written consent given under and subject to the
terms of Paragraph 36.

                     (b) A change in the control of Lessee shall constitute an
assignment requiring Lessor's consent. The transfer, on a cumulative basis of
fifty percent (50%) or more of the voting control of Lessee shall constitute a
change in control for this purpose.

                     (c) N/A

                     (d) An assignment or subletting of Lessee's interest in
this Lease without Lessor's specific prior written consent shall, at Lessor's
option, be a Default curable after notice per Paragraph 13.1, or a non-curable
Breach without the necessity of any notice and grace period. If Lessor elects to
treat such unconsented to assignment or subletting as a non-curable Breach,
Lessor shall have the right to either (i) terminate this Lease, or (ii) upon
thirty (30) days' written notice ("LESSOR'S NOTICE"), increase the monthly Base
Rent for the Premises to the greater of the then fair market rental value of the
Premises, as reasonably determined by Lessor, or one hundred ten percent (110%)
of the Base Rent then in effect. Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with an overpayment credited against the next installment(s) of
Base Rent coming due, and any underpayment for the period retroactively to the
effective date of the adjustment being due and payable immediately upon the
determination thereof. Further, in the event of such Breach and rental
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
as reasonably determined by Lessor (without the Lease being considered an
encumbrance or any deduction for depreciation or obsolescence, and considering
the Premises at its highest and best use and in good condition) or one hundred
ten percent (110%) of the price previously in effect, (ii) any index-oriented



                                      -15-
<PAGE>   16

rental or price adjustment formulas contained in this Lease shall be adjusted to
require that the base index be determined with reference to the index applicable
to the time of such adjustment, and (iii) any fixed rental adjustments scheduled
during the remainder of the Lease term shall be increased in the same ratio as
the new rental bears to the Base Rent in effect immediately prior to the
adjustment specified in Lessor's Notice.

                     (e) Lessee's remedy for any breach of this Paragraph 12.1
by Lessor shall be limited to compensatory damages and/or injunctive relief.

           12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

                     (a) Regardless of Lessor's consent, any assignment or
subletting shall not (i) be effective without the express written assumption by
such assignee or sublessee of the obligations of Lessee under this Lease, (ii)
release Lessee of any obligations hereunder, nor (iii) alter the primary
liability of Lessee for the payment of Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

                     (b) Lessor may accept any rent or performance of Lessee's
obligations from any person other than Lessee pending approval or disapproval of
an assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of any rent for performance shall constitute a waiver or
estoppel of Lessor's right to exercise its remedies for the Default or Breach of
Lessee of any of the terms, covenants or conditions of this Lease.

                     (c) The consent of Lessor to any assignment or subletting
shall not constitute a consent to any subsequent assignment or subletting by
Lessee or to any subsequent or successive assignment or subletting by the
assignee or sublessee. However, Lessor may consent to subsequent sublettings and
assignments of the sublease or any amendments or modifications thereto without
notifying Lessee or anyone else liable under this Lease or the sublease and
without obtaining their consent, and such action shall not relieve such persons
from liability under this Lease or the sublease.

                     (d) In the event of any Default or Breach of Lessee's
obligation under this Lease, Lessor may proceed directly against Lessee, any
Guarantors or anyone else responsible for the performance of the Lessee's
obligations under this Lease, including any sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor.

                     (e) Each request for consent to an assignment or subletting
shall be in writing, accompanied by Information relevant to Lessor's
determination as to the financial and operational responsibility and
appropriateness of the proposed assignee or sublessee, including not limited to
the intended use and/or required modification of the Premises, if any, together
with a non-refundable deposit of $1,000 or ten percent (10%) of the monthly Base
Rent applicable to the portion of the Premises which is the subject of the
proposed assignment or sublease, whichever is greater, as reasonable
consideration for Lessor's considering and processing the request for consent.
Lessee agrees to provide Lessor with such other or additional information and/or
documentation as may be reasonably requested by Lessor.

                     (f) Any assignee of, or sublessee under, this Lease shall,
by reason of accepting such assignment or entering into such sublease, be
deemed, for the benefit of Lessor, to have assumed and agreed to conform and
comply with each and every term, covenant, condition and obligation herein to be
observed or performed by Lessee during the term of said assignment or sublease,
other than such obligations as are contrary to or inconsistent with provisions
of an assignment or sublease to which Lessor has specifically consented in
writing.

                     (g) The occurrence of a transaction described in Paragraph
12.2(c) shall give Lessor the right (but not the obligation) to require that the
Security Deposit be increased by an amount equal to six (6) times the then
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the
Security Deposit increase a condition to Lessor's consent to such transaction.

                     (h) Lessor, as a condition to giving its consent to any
assignment or subletting, may require that the amount and adjustment schedule of
the rent payable under this Lease be adjusted to what is then the market value
and/or adjustment schedule for property similar to the Premises as then
constituted, as determined by Lessor.

           12.3 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

                     (a) Lessee hereby assigns and transfers to Lessor all of
Lessee's interest in all rentals and income arising from any sublease of all or
a portion of the Premises heretofore or hereafter made by Lessee and Lessor may
collect such rent and income and apply same toward Lessee's obligations under
this Lease; provided, however, that until a Breach (as defined in Paragraph
13.1) shall occur in the performance of Lessee's obligations under this Lease,
Lessee may, except as otherwise provided in this Lease, receive, collect and
enjoy the rents accruing under such sublease, Lessor shall not, by reason of the
foregoing provision of any other assignment of such sublease to Lessor, nor by
reason of the collection of the rents from a sublessee, be deemed liable to the
sublessee for any failure of Lessee to perform and comply with any of Lessee's
obligations to such sublessee under such Sublease. Lessee hereby irrevocably
authorizes and directs any such sublessee, upon receipt of a written notice from
Lessor stating that a Breach exists in the performance of Lessee's obligations
under this Lease, and shall pay such rents and other charges to Lessor without
any obligation or right to inquire as to whether such Breach exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against such sublessee, or, until the Breach has
been cured, against Lessor, for any such rents and other charges so paid by said
sublessee to Lessor.

                     (b) In the event of a Breach by Lessee in the performance
of its obligations under this Lease, Lessor, at its option and without any
obligation to do so, may require any sublessee to attorn to Lessor, in which
event Lessor shall undertake the obligations of the sublessor under such
sublease from the time of the exercise of said option to the expiration of such
sublease; provided, however, Lessor shall not be liable for any prepaid rents or
security deposit paid by such sublessee to such sublessor or for any other prior
defaults or breaches under such sublease.

                     (c) Any matter or thing requiring the consent of the
sublessor under a sublease shall also require the consent of Lessor herein.

                     (d) No sublessee under a sublease approved by Lessor shall
further assign or sublet all or part of the Premises without Lessor's prior
written consent.

                     (e) Lessor shall deliver a copy of any notice of Default or
Breach by Lessee to the sublessee, who shall have the right to cure the Default
of Lessee within the grace period, if any, specified in such notice. The
sublessee shall have a right of reimbursement and offset from and against Lessee
for any such Defaults cured by the sublessee.

13. DEFAULT; BREACH; REMEDIES.

           13.1 DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $35,000 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and services of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said default. A "DEFAULT" by Lessee is
defined as a failure by Lessee to observe, comply with or perform any of the
terms, covenants, conditions or rules, applicable to Lessee under this Lease. A
"BREACH" by Lessee is defined as the occurrence of any one or more of the
following Defaults, and, where a grace period for cure after notice is specified
herein, the failure by Lessee to cure such Default prior to the expiration of
the expiration of the applicable grace period, and shall entitle Lessor to
pursue the remedies set forth in Paragraphs 13.2 and/or 13.3:

                     (a) Without Landlord consent, which shall not be
unreasonably withheld, the vacating of the Premises without the intention to
reoccupy same, or the abandonment of the Premises.

                     (b) Except as expressly otherwise provided in this Lease,
the failure by Lessee to make any payment of Base Rent, Lessee's Share of Common
Area Operating Expenses, or any other monetary payment required to be made by
Lessee hereunder as and when due, the failure by Lessee to provide Lessor with
reasonable evidence of insurance or surety bond required under this Lease, or
the failure of Lessee to fulfill any obligation under this Lease 



                                      -17-
<PAGE>   18

which endangers or threatens life or property, where such failure continues for
a period of three (3) days following written notice thereof by or on behalf of
Lessor to Lessee.

                     (c) Except as expressly otherwise provided in this Lease,
the failure by Lessee to provide Lessor with reasonable written evidence (in
duly executed original form, if applicable) of (i) compliance with Applicable
Requirements per Paragraph 6.3 (ii) the inspection, maintenance and service
contracts required under Paragraph 7.1(b), (iii) the rescission of an
unauthorized assignment or subletting per Paragraph 12.1, (iv) a Tenancy
Statement per Paragraphs 16 or 37, (v) the subordination or non-subordination of
this Lease per Paragraph 30, (vi) the guaranty of the performance of Lessee's
obligations under this Lease if required under Paragraphs 1.11 and 37, (vii) the
execution of any document requested under Paragraph 42 (easements), or (viii)
any other documentation or information which Lessor may reasonably require of
Lessee under the terms of this lease, where such failure continues for a period
of (10) days following written notice by or on behalf of Lessor to Lessee.

                     (d) A Default by Lessee as to the terms, covenants,
conditions or provisions of this Lease, or of the rules adopted under Paragraph
40 hereof that are to be observed, complied with or performed by Lessee, other
than those described in Subparagraphs 13.1(a), (b) or (c), above, where such
Default continues for a period of thirty (30) days after written notice thereof
by or on behalf of Lessor to Lessee; provided, however, that if the nature of
Lessee's Default is such that more than thirty (30) days are reasonably required
for its cure, then it shall not be deemed to be a Breach of this Lease by Lessee
if Lessee commences such cure within said thirty (30) day period and thereafter
diligently prosecutes such cure to completion.

                     (e) The occurrence of any of the following events: (i) the
making by Lessee of any general arrangement or assignment for the benefit of
creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code Section
101 or any successor statute thereto (unless, in the case of a petition filed
against Lessee, the same is dismissed within sixty (60) days); (iii) the
appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this Subparagraph 13.1(e) is contrary to any
applicable law, such provision shall be of no force or effect, and shall not
affect the validity of the remaining provisions.

                     (f) The discovery by Lessor that any financial statement of
Lessee or of any Guarantor, given to Lessor by Lessee or any Guarantor, was
materially false.

                     (g) If the performance of Lessee's obligations under this
Lease is guaranteed: (i) the death of a Guarantor, (ii) the termination of a
Guarantor's liability with respect to this Lease other than in accordance with
the terms of such guaranty, (iii) a Guarantor's becoming insolvent or the
subject of a bankruptcy filing, (iv) a Guarantor's refusal to honor the
guaranty, or (v) a Guarantor's breach of its guaranty obligation on an
anticipatory breach basis, and Lessee's failure, within sixty (60) days
following written notice by or on behalf of Lessor to Lessee of any such event,
to provide Lessor with written alternative assurances of security, which, when
coupled with the then existing resources of Lessee, equals or exceeds the
combined financial resources of Lessee and the Guarantors that existed at the
time of execution of this Lease.

           13.2 REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), perform such duty or obligation on Lessee's
behalf, including but not limited to the obtaining of reasonably required bonds,
insurance policies, or governmental licenses, permits or approvals. The costs
and expenses of any such performance by Lessor shall be due and payable by
Lessee to Lessor upon invoice therefor. If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is drawn, Lessor, at its own
option, may require all future payments to be made under this Lease by Lessee to
be made only by cashier's check. In the event of a Breach of this Lease by
Lessee (as defined in Paragraph 13.1), with or without further notice or demand,
and without limiting Lessor in the exercise of any right or remedy which Lessor
may have by reason of such Breach, Lessor may:



                                      -18-
<PAGE>   19

                     (a) Terminate Lessee's right to possession of the Premises
by any lawful means, in which case this Lease and the term hereof shall
terminate and Lessee shall immediately surrender possession of the Premises to
Lessor. In such event Lessor shall be entitled to recover from Lessee: (i) the
worth at the time of the award of unpaid rent which had been earned at the time
of termination; (ii) the worth at the time of the award of the amount by which
the unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, 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, and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease. The worth at the time of the
award of the amount referred to in provision (iii) of the immediately preceding
sentence shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco or the Federal Reserve Bank District
in which the Premises are located at the time of award plus one percent (1%).
Efforts by Lessor to mitigate damages caused by Lessee's Default or Breach of
this Lease shall not waive Lessor's right to recover damages under this
Paragraph 13.2. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding the unpaid rent and damages as are recoverable therein, or Lessor may
reserve the right to recover all or any part thereof in a separate suit for such
rent and/or damages. If a notice and grace period required under Subparagraph
13.1 (b), (c) or (d) was not previously given, a notice to pay rent or quit, or
to perform or quit, as the case may be, given to Lessee under any statute
authorizing the forfeiture of leases for unlawful detainer shall also constitute
the applicable notice for grace period purposes required by Subparagraph
13.1(b),(c) or (d). In such case, the applicable grace period under the unlawful
detainer statue shall run concurrently after the one such statutory notice, and
the failure of Lessee to cure the Default within the greater of the two (2) such
grace periods shall constitute both an unlawful detainer and a Breach of this
Lease entitling Lessor to the remedies provided for in this Lease and/or by said
statute.

                     (b) Continue the Lease and Lessee's right to possession in
effect (in California under California Civil Code Section 1951.4) after Lessee's
Breach and recover the rent as it becomes due, provided Lessee has the right to
sublet or assign, subject only to reasonable limitations. Lessor and Lessee
agree that the limitations on assignment and subletting in this Lease are
reasonable. Acts of maintenance or preservation, efforts to relet the Premises,
or the appointment of a receiver to protect the Lessor's interest under this
Lease, shall not constitute a termination of the Lessee's right to possession.

                     (c) Pursue any other remedy now or thereafter available to
Lessor under the laws or judicial decisions of the state wherein the Premises
are located.

                     (d) The expiration or termination of this Lease and/or the
termination of Lessee's right to possession shall not relieve lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

           13.3 INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor
for free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "INDUCEMENT PROVISIONS" shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach (as defined in Paragraph 13.1) of this Lease by Lessee, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor, as additional rent due under this Lease,
notwithstanding any subsequent cue of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph 13.3 shall not be deemed a waiver by Lessor of the provisions of the
Paragraph 13.3 unless specifically so stated in writing by Lessor at the time of
such acceptance.



                                      -19-
<PAGE>   20

           13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of rent and other sums due hereunder will cause Lessor 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
Lessor by the terms of any ground lease, mortgage or deed of trust covering the
Premises. Accordingly, if any installment of rent or other sum due from Lessee
shall not be received by Lessor or Lessor's designee when due, then, without any
requirement for notice to Lessee, Lessee shall pay to Lessor a late charge equal
to six percent (6%) of such overdue amount. The parties hereby agree that such
late charge represents a fair and reasonable estimate of the costs Lessor will
incur by reason of late payment by Lessee. Acceptance of such late charge by
Lessor shall in no event constitute a waiver of Lessee's Default or Breach with
respect to such overdue amount, nor prevent Lessor from exercising any of the
other rights and remedies granted hereunder. In the event that a late charge is
payable hereunder, whether or not collected, for three (3) consecutive
installments of Base Rent, then notwithstanding Paragraph 4.1 or any other
provision of this Lease to the contrary, Base Rent shall, at Lessor's option,
become due and payable quarterly in advance.

           13.5 BREACH OF LESSOR. Lessor shall not be deemed in breach of this
Lease unless Lessor fails within a reasonable time to perform an obligation
required to be performed by Lessor. For purposes of this Paragraph 13.5, a
reasonable time shall in no event be less than thirty (30) days after receipt by
Lessor, and by any Lender(s) whose name and address shall have been furnished to
Lessee in writing for such purpose, of written notice specifying wherein such
obligation of Lessor has not been performed; provided, however, that if the
nature of Lessor's obligation is such that more than thirty (30) days after such
notice are reasonably required for its performance, then Lessor shall not be in
breach of this Lease if performance is commenced with such thirty (30) day
period and thereafter diligently pursued to completion.

14. CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(all of which are herein called "condemnation"), this Lease shall terminate as
to the part so taken as of the date the condemning authority takes title or
possession, whichever first occurs. If more than ten percent (10%) of the floor
area of the Premises, or more than twenty-five percent (25%) of the portion of
the Common Areas designated for Lessee's parking, is taken by condemnation,
Lessee may, at Lessee's option, to be exercised in writing within ten (10) days
after Lessor shall have given Lessee written notice of such taking (or in the
absence of such notice, with ten (10) days after the condemning authority shall
have taken possession) terminate this Lease as of the date the condemning
authority takes such possession. If Lessee does not terminate this Lease in
accordance with the foregoing, this Lease shall remain in full force and effect
as to the portion of the Premises remaining, except that the Base Rent shall be
reduced in the same proportion as the rentable floor area of the Premises taken
bears to the total rentable floor area of the Premises. No reduction of Base
Rent shall occur if the condemnation does not apply to any portion of the
Premises. Any award for the taking of all or any part of the Premises under the
power of eminent domain or any payment made under threat of the exercise of such
power shall be the property of Lessor, whether such award shall be made as
compensation for diminution of value of the leasehold or for the taking of the
fee, or as severance damages; provided, however, that Lessee shall be entitled
to any compensation, separately awarded to Lessee for Lessee's relocation
expenses and/or loss of Lessee's Trade Fixtures. In the event that this Lease is
not terminated by reason of such condemnation, Lessor shall to the extent of its
net severance damages received, over and above Lessee's Share of the legal and
other expenses incurred by Lessor in the condemnation matter, repair any damage
to the Premises caused by such condemnation authority. Lessee shall be
responsible for the payment of any amount in excess of such net severance
damages required to complete such repair.

15. Each Broker shall be an intended third party beneficiary of the provisions
of Paragraph 10 and of this 



                                      -20-

Lease and may enforce that right directly against Lessor and its successors.

broker or finder other than as named in Paragraph 1.10(a) in connection with the
negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fee in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnify, protect, defend and hold the other harmless from and against
liability for compensation or charges which may be claimed by any such unnamed
broker, finder or other similar party by reason of any dealings or actions of
the indemnifying Party, including any costs, expenses, and/or attorneys fees
reasonably incurred with respect thereto.

16. TENANCY AND FINANCIAL STATEMENTS.

           16.1 TENANCY STATEMENT. Each Party (as "RESPONDING PARTY") shall
within ten (10) days after written notice from the other Party (the "REQUESTING
PARTY") execute, acknowledge and deliver to the Requesting Party a statement in
writing in a form similar to the then most current "TENANCY STATEMENT" form
published by the American Industrial Real Estate Association, plus such
additional information, confirmation and/or statements as may be reasonably
requested by the Requesting Party.

           16.2 FINANCIAL STATEMENT. If Lessor desires to finance, refinance, or
sell the Premises or the Building, or any part thereof, Lessee and all
Guarantors shall deliver to any potential lender or purchaser designated by
Lessor such financial statements of Lessee and such Guarantors as may be
reasonably required by such lender or purchaser, including but not limited to
Lessee's financial statements of the past three (3) years. All such financial
statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17. LESSOR'S LIABILITY. The term "LESSOR" as used herein shall mean the owner or
owners at the time in question of the fee title to the Premises. In the event of
a transfer of Lessor's title or interest in the Premises or in this Lease.
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in :Paragraph 15.3, upon such transfer or
assignment and delivery of the Security Deposit, as aforesaid, the prior Lessor
shall be relieved of all liability with respect to the obligations and/or
covenants under this Lease thereafter to be performed by the Lessor. Subject to
the foregoing, the obligations and/or covenants in this Lease to be performed by
the Lessor shall be binding only upon the Lessor as hereinabove defined.

18. SEVERABILITY. The invalidity of any provision of this Leased, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19. INTEREST ON PAST-DUE OBLIGATIONS. Any monetary payment due Lessor hereunder,
other than late charges, not received by Lessor within ten (10) days following
the date on which it was due, shall bear interest from the date due at the prime
rate charged by the largest state chartered bank in the state in which the
Premises are located plus four percent (4%) per annum, but not exceeding the
maximum rate allowed by law, in addition to the potential late charge provided
for in Paragraph 13.4.

20. TIME OF ESSENCE. Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

21. RENT DEFINED. All monetary obligations of Lessee to Lessor under the terms
of this Lease are deemed to be rent.

22. NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own investigation as to the nature, quality,
character and financial responsibility of the other Party to this Lease and as
to the nature, quality and character of the Premises. Brokers have no
responsibility with 



                                      -21-
<PAGE>   22

respect thereto or with respect to any default or breach hereof by either Party.
Each Broker shall be an intended third party beneficiary of the provisions of
this Paragraph 22.

23. NOTICES.

           23.1 NOTICE REQUIREMENTS. All notices required or permitted by this
Lease shall be in writing and may be delivered in person (by hand or by
messenger or courier service) or may be sent by regular, certified or registered
mail or U.S. Postal Service Express Mail, with postage prepaid, or by facsimile
transmission during normal business hours, and shall be deemed sufficiently
given if served in a manner specified in this Paragraph 23. The addresses noted
adjacent to a Party's signature on this Lease shall be that Party's address for
delivery or mailing of notice purposes, except that upon Lessee's taking
possession of the Premises, the Premises shall constitute Lessee's address for
the purpose of mailing or delivering notices to Lessee. A copy of all notices
required or permitted to be given to Lessor hereunder shall be concurrently
transmitted to such party or parties at such addresses as Lessor may from time
to time hereafter designate by written notice to Lessee.

           23.2 DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given forty-eight (48) hours after
the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantees next day delivery shall be deemed given twenty-four (24) hours after
delivery of the same to the United States Postal Service or courier. If any
notice is transmitted by facsimile transmission or similar means, the same shall

holiday, it shall be deemed received on the next business day.

24. WAIVERS. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any such act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any such act shall not be
deemed to render unnecessary the obtaining of Lessor's consent to, or approval
of, any subsequent or similar act by Lessee, or be construed as the basis of an
estoppel to enforce the provision of provisions of this Lease requiring such
consent. Regardless of Lessor's knowledge of a Default or Breach at the time of
accepting rent, the acceptance of rent by Lessor shall not be a waiver of any
Default or Breach by Lessee of any provision hereof. Any payment given Lessor by
Lessee may be accepted by Lessor on account of moneys or damages due Lessor,
notwithstanding any qualifying statements or conditions made by Lessee in
connection therewith, which such statements and/or conditions shall be of no
force or effect whatsoever unless specifically agreed t in writing by Lessor at
or before the time of deposit of such payment.

25. RECORDING.Either Lessor or Lessee shall, upon request of the other, execute,
acknowledge and deliver to the other a short form memorandum of this Lease for
recording purposes. The Party requesting recordation shall be responsible for
payment of any fees or taxes applicable thereto.

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease. In the event that Lessee holds over in violation of this Paragraph
26 then the Base Rent payable from and after the time of the expiration or
earlier termination of this Lease shall be increased to one hundred fifty
percent (150%) of the Base Rent applicable during the month immediately
preceding such expiration or earlier termination. Nothing contained herein shall
be construed as a consent by Lessor to any holding over by Lessee.

27. CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies a
law or in equity.

28. COVENANTS AND CONDITIONS. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.



                                      -22-
<PAGE>   23

29. BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the Parties,
their personal representatives, successors, and assigns and be governed by the
laws of the State in which the Premises are located. Any litigation between the
Parties hereto concerning this Lease shall be initiated in the county in which
the Premises are located.

30. SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

           30.1 SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all advances
made on the security thereof, and to all renewals, modifications,
consolidations, replacement and extensions thereof. Lessee agrees that the
Lenders holding any such Security Device shall have no duty, liability or
obligation to perform any of the obligations of Lessor under this Lease, but
that in the event of Lessor's default with respect to any such obligation,
Lessee will give any Lender whose name and address have been furnished Lessee in
writing for such purpose notice of Lessor's default pursuant to Paragraph 13.5.
If any Lender shall elect to have this Lease and/or any Option granted hereby
superior to the lien of its Security Device and shall give written notice
thereof to Lessee, this Lease and such Options shall be deemed prior to such
Security Device, notwithstanding the relative dates of the documentation or
recordation thereof.

           30.2 ATTORNMENT. Subject to the non-disturbance provisions of
Paragraph 30.3, Lessee agrees to attorn to a Lender or any other party who
acquires ownership of the Premises by reason of a foreclosure of a Security
Device, and that in the event of such foreclosure, such new owner shall not: (i)
be liable for any act of omission of any prior lessor or with respect to events
occurring prior to acquisition of ownership (ii) be subject to any offsets or
defenses which Lessee might have against any prior lessor, or (iii) be bound by
prepayment o more than one month's rent.

           30.3 NON-DISTURBANCE. With respect to Security Devices entered into
by Lessor after the execution of this lease, Lessee's subordination of this
Lease shall be subject to receiving assurance (a "non-disturbance agreement")
from the Lender that Lessee's possession and this Lease, including any options
to extend the term hereof, will not be disturbed so long as Lessee is not in
Breach hereof and attorns to the record owner of the Premises.

           30.4 SELF-EXECUTING. The agreements contained in this Paragraph 30
shall be effective without the execution of any further documents; provided,
however, that upon written request from Lessor or a Lender in connection with a
sale, financing of refinancing of Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31. ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonably attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "PREVAILING PARTY" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. The
attorneys fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees reasonably
incurred. Lessor shall be entitled to reasonable attorneys' fees, costs and
expenses incurred in preparation and service of notices of Default and
consultations in connection therewith, whether or not a legal action is
subsequently commenced in connection with such Default or resulting Breach.
Broker(s) shall be intended third party beneficiaries of this Paragraph 31.

32. LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonably times for the purpose of showing the same to
prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the Building, as Lessor
may reasonably deem necessary. Lessor may at any time place on or about the
Premises or Building any ordinary "For Sale" signs and Lessor may at any time
during the last one hundred eighty (180) days of the term hereof place on or
about the Premises any ordinary "For Lease" signs. All such activities of Lessor
shall be without abatement of rent or liability to Lessee.



                                      -23-
<PAGE>   24

33. AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily, any auction upon the Premises without first having obtained
Lessor's prior written consent. Notwithstanding anything to the contrary in this
Lease, Lessor shall not be obligated to exercise any standard of reasonableness
in determining whether to grant such consent.

34. SIGNS. Lessee shall not place any sign upon the exterior of the Premises or
the Building, except that Lessee may, with Lessor's prior written consent,
install (but not on the roof) such signs as are reasonably required to advertise
Lessee's own business so long as such signs are in a location designated by
Lessor and comply with Applicable Requirements and the signage criteria
established for the Industrial Center by Lessor. The installation of any sign on
the Premises by or for Lessee shall be subject to the provisions of Paragraph 7
(Maintenance, Repairs, Utility Installations, Trade Fixtures and Alterations).
Unless otherwise expressly agreed herein, Lessor reserves all rights to the use
of the roof of the Building, and the right to install advertising signs on the
Building, including the roof, which do not unreasonably interfere with the
conduct of Lessee's business; Lessor shall be entitled to all revenues from such
advertising signs.

35. TERMINATION; MERGER. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, Lessor shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of any
existing subtenancies. Lessor's failure within ten (10) days following any such
event to make a written election to the contrary by written notice to the holder
of any such lesser interest, shall constitute Lessor's election to have such
event constitute the termination of such interest.

36. CONSENTS.

                     (a) Except for Paragraph 33 hereof (Auctions) or as
otherwise provided herein, wherever in this Lease the consent of a Party is
required to an act by or for the other Party, such consent shall not be
unreasonably withheld or delayed. Excluding initial Lessee ("tenant")
improvements Lessor's actual reasonably costs and expenses (including but not
limited to architects', attorneys', engineers' and other consultants' fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment a subletting or the presence or use of a
Hazardous Substance, shall be paid by Lessee to Lessor upon receipt of an
invoice and supporting documentation therefor. In addition to the deposit
described in Paragraph 12.2(e), Lessor may, as a condition to considering any
such request by Lessee, require that Lessee deposit with Lessor an amount of
money (in addition to the Security Deposit held under Paragraph 5) reasonably
calculated by Lessor to represent the cost Lessor will incur in considering and
responding to Lessee's request. Any unused portion of said deposit shall be
refunded to Lessee without interest. Lessor's consent to any act, assignment of
this Lease or subletting of the Premises by Lessee shall not constitute an
acknowledgment that no Default or Breach by Lessee of this Lease exists, nor
shall such consent be deemed a waiver of any then existing Default or Breach,
except as may be otherwise specifically stated in writing by Lessor at the time
of such consent.

                     (b) All conditions to Lessor's consent authorized by this
Lease are acknowledged by Lessee as being reasonable. The failure to specify
herein any particular condition to Lessor's consent shall not preclude the
impositions by Lessor at the time of consent of such further or other conditions
as are then reasonable with reference to the particular mater for which consent
is being given.

37. GUARANTOR.

           37.1 FORM OF GUARANTY. If there are to be any Guarantors of this
Lease per Paragraph 1.11, the form of the guaranty to be executed by each such
Guarantor shall be in the form most recently published by the American
Industrial Real Estate Association, and each such Guarantor shall have the same
obligations as Lessee under this lease, including but not limited to the
obligation to provide the Tenancy Statement and information required in
Paragraph 16.

           37.2 ADDITIONAL OBLIGATIONS OF GUARANTOR. It shall constitute a
Default of this Lease if any such Guarantor fails or refuses, upon reasonably
request by Lessor to give: (a) evidence of the due execution of the 



                                      -24-
<PAGE>   25

guaranty called for by this Lease, including the authority of the Guarantor (and
of the party signing on Guarantor's behalf) to obligate such Guarantor on said
guaranty, and resolution of its board of directors authorizing the making of
such guaranty, together with a certificate of incumbency showing the signatures
of the persons authorized to sign on its behalf, (b) current financial
statements of Guarantor as may from time to time be requested by Lessor, (c) a
Tenancy Statement, or (d) written confirmation that the guaranty is still in
effect.

38. QUIET POSSESSION. Upon payment by Lessee of the rent for the Premises and
the performance of all of the covenants, conditions and provisions on Lessee's
part to be observed and performed under this Lease, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.

39. OPTIONS.

           39.1 DEFINITION. As used in this Lease, the word "OPTION" has the
following meaning: (a) the right to extend the term of this Lease or to renew
this Lease or to extend or renew any lese that Lessee has on other property of
Lessor; (b) the right of first refusal to lease the Premises or the right of
first offer to lease the Premises or the right of first refusal to lease other
property of Lessor or the right of first offer to lease other property of
Lessor; (c) the right to purchase the Premises, or the right of first refusal to
purchase the Premises, or the right of first offer to purchase the Premises, or
the right to purchase other property of Lessor, or the right of first refusal to
purchase other property of Lessor, or the right of first offer to purchase other
property of Lessor.

           39.2 OPTIONS PERSONAL TO ORIGINAL LESSEE. Each Option granted to
Lessee in this Lease is personal to the original Lessee named in Paragraph 1.1
hereof, and cannot be voluntarily or involuntarily assigned or exercised by any
person or entity other than said original Lessee while the original Lessee is in
full and actual possession of the Premises and without the intention of
thereafter assigning or subletting. The Options, if any, herein granted to
Lessee are not assignable, either as a part of an assignment of this Lese or
separately or apart therefrom, and no Option may be separated from this Lease in
any manner, by reservation or otherwise.

           Lessee at Lessee's sole cost. Lessor Shall make no improvements to
           the Premises and shall deliver possession of the Premises to Lessee
           in an "as is" condition. Lessee accepts possession of the Premises in
           their "as is" condition and hereby waives any right or claim against
           Lessor for any cause directly or indirectly arising out of the

           or equipment therein, and Lessor shall not be liable for any latent
           or patent defects therein. Nothing contained in this paragraph,
           however, shall be deemed to limit Lessor's obligation to repair the
           Premises wherever such obligation is expressly set forth in the
           Lease.

           All improvements to the Premises being made by Lessee shall be
           considered as Alterations or Utility Installations as such terms are
           defined in Paragraph 7.3 of the Lease, and Lessee shall carefully
           adhere to all obligations and procedures therefore set out in said
           Paragraph 7.3 and Paragraph 7.4 of the Lease, including but not
           limited to the preparation of improvements plans, obtaining Lessor's
           consent to such plans and obtaining governmental approvals. After
           submission to it of Lessee's plans, Lessor shall have five (5)
           business days to examine and approve them. If Lessor disapproves
           Lessee's plans, it shall deliver a written statement to Lessee within
           five (5) business day period setting forth its objections in
           reasonable detail. In the event Lessor does not deliver such written
           objections to Lessee with such five (5) business day period, Lessor
           shall be deemed to have approved Lessee's plans.

           Lessee shall only use contractors and subcontractors which have
           procured, paid for and maintained public liability insurance in an
           amount not less than $1,000,000,00 and which are licensed in the
           State of California. Prior to commencement of such work, Lessee shall
           cause each of its contractors and subcontractors to furnish Lessee
           with a certificate from their respective public liability insurers
           evidencing such coverage, naming Lessor as an additional insured and
           providing for severability of interests or containing a
           cross-liability endorsement. Lessee shall, upon final completion of
           its work, furnish Lessor with all certificates, lien releases and
           approvals relating to any work or installations performed by Lessee
           that may be required by any governmental or insurance requirements.

51.        Option to Extend:

           For the purposes of this Lease, the term "Previous Period" shall mean
           the Original Term of this Lease.

           Provided Lessee is not and has never been in default under any of the
           terms and conditions of the Lease and has not assigned or sublet the
           Premises to another tenant, Lessee shall have the option to extend
           the Term of this Lease for one (1) additional three (3) year period
           upon the same terms and conditions except that the Base Rent at the
           commencement of such option period shall be increased to the Fair
           Market Rent at the time of commencement of such option period, as
           determined in accordance with the following paragraphs of this
           Paragraph 51. In no event shall the Base Rent at the commencement of
           such option period be less than the Base Rent for the last year of
           the Previous Period. Lessee's Base Rent, as established upon
           commencement of such option period, shall thereafter be increased
           commencing on the first day of the month next following 



                                      -29-

           the passage of the initial twelve (12) calendar months of such option
           period and on the first day of the month next following the passage
           of each successive twelve (12) calendar months of such option period
           (each of which shall be referred to as an "Adjustment Date"). On each
           Adjustment Date, the Base Rent shall be increased by an amount
           calculated by comparing the CPI for the month which is four (4)
           months prior to the Adjustment Date (the "Adjustment Index") with the
           CPI for the calendar month which is four (4) months prior to the
           month in which such option period commenced (the "Option Index") and
           then adjusting the Base Rent paid during the first year of such
           option period by the percentage increase of the Adjustment Index over
           the Option Index. In no event shall the increase in the Base Rent for
           any twelve (12) months of such option period be less than five
           percent (5%) nor greater than eight percent (8%) of the Base Rent for
           the preceding twelve (12) months of such option period.

           If Lessee intends to exercise this option to extend the Term, then
           not more than two hundred and seventy (270) days nor less than two
           hundred and forty (240) days prior to the expiration of the Previous
           Period, Lessee shall deliver to Lessor a notice of its intention to
           exercise its option to extend ("Notice of Intention"). Within ten
           (10) days of the delivery to Lessor of the Notice of Intention,
           Lessor and Lessee shall meet to determine, in good faith, what they
           consider to be the Fair Market Rent based upon this Lease and the
           terms, covenants, and rights provided for in the Lease. In
           determining the Fair Market Rent for the Premises, the primary
           consideration shall be lease transactions recently executed within
           the market area with appropriate adjustments being made for location,
           type of tenant, building attributers, lease term and financial
           condition of Lessee. In the event Lessor and Lessee are unable to
           agree on the Fair Market Rent within thirty (30) days after delivery
           of the Notice of Intention, the Fair Market Rent shall be determined
           as follows: Lessor and Lessee shall cause an appraisal to be made of
           the then-current rental value of three (3) appraisers, each of whom
           shall be an MAI appraiser with at lease five (5) years experience
           appraising leases in industrial building in the Orange County area.
           Lessor and Lessee, each at its own cost, shall each select one (1)
           appraiser who shall complete an appraisal and each shall immediately
           notify the other of the appraiser so selected. Such selections shall
           be made no later than the earlier of: (I) ten (10) days after the
           date on which Lessor and Lessee agree that they are unable to agree
           on the Fair Market Rent: or (ii) forty (40) days after delivery of
           the Notice of Intention. The two appraisers so selected shall select
           a third appraiser. Lessor and Lessee shall each bear one-half (1/2)
           of the costs of selecting the third appraiser and of paying the third
           appraiser's fee. The third appraiser, however selected, shall be a
           person who is not and who has not previously been an agent or
           employee of either Lessor or Lessee. In the event the two appraisers
           are unable to agree upon the selection of a third appraiser, the two
           appraisers shall, within five (5) days after the date on which they
           agree they are unable to agree on a third appraiser, request the
           Presiding Judge of the Superior Court in and for the County of
           Orange, State of California, to appoint the third appraiser. Within
           thirty (30) days after the selection of the third appraiser, a
           majority of the appraiser's shall establish the Fair Market Rent. If
           no two appraisers agree on the current Fair Market Rent, the
           appraisal which is neither highest nor lowest shall control.

           The option to extend shall be exercised by Lessee by delivering to
           Lessor written notice ("Notice of Exercise") no less than one hundred
           ten (110) days prior to the expiration of the Previous Period;
           provided, however, that if the Fair Market Rent has not been
           established by one hundred twenty (120) days prior to the expiration
           of the Previous Period due to failure of Lessor to comply with the
           time periods set forth herein, then the date by which the option to
           extend must be exercised shall be extended for a period equal to
           Lessor's delay. If, for any reason other than the failure of Lessor
           to comply with the time periods set forth herein, Lessee has not
           delivered to Lessor its Notice of Exercise by one hundred ten (110)
           days prior to the expiration of the Previous Period, Lessee shall
           have no option to extend the term of the Lease.

52.        Security Deposit Reduction:

           If on February 2, 1999 and/or on February 2, 2000, Lessee (1) shall
           have paid its Base Rent and all other charges due under this Lease on
           a timely basis for all of the twelve (12) preceding months (March
           1998 through February 1999 and March 1999 through February 2000) and
           (2) shall have otherwise never been in default of this Lease, then on
           February 2, 1999 and/or on February 2, 2000 the amount of the
           Security Deposit shall be reduced by $17,001.70, and such amount
           shall be credited to Lessee's account.
