other terms of this Lease, however, (including but not limited to the

perform any other obligation of Lessee under the terms of this Lease until

amount of such over-


                                       -2-




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 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 within 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. Any 
time the Base Rent increases during the term of this Lease, Lessee shall, 
upon written request from Lessor, deposit additional monies with Lessor as an 
addition to the Security Deposit so that the total amount of the Security 
Deposit shall at all times bear the same proportion to the then current Base 
Rent as the initial Security Deposit bears to the initial Base Rent set forth 
in Paragraph 1.5. 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, or 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.

6.  USE.

     6.1 PERMITTED USE.

         (a) Lessee shall use and occupy the Premises only for the Permitted 
Use set forth in Paragraph 1.6, 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.

     6.2 HAZARDOUS SUBSTANCES.

         (a) REPORTABLE USES REQUIRE CONSENT. The term "Hazardous Substances" 
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 of 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) 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 obligations 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, upon reasonable notice, 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 cost 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.

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

     7.1 LESSEE'S OBLIGATIONS.

         (a) Subject to the provisions of Paragraphs 2.2 (Condition). 2.3 
(Compliance with Covenants, Restrictions and Building Code), 7.2 (Lessor's 
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 or 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 or renewals when necessary to keep the 
Premises and all improvements thereon or a part thereof in good order, 
condition and state of repair.

         (b) Lessee shall, at Lessee's sole cost and expense, procure and 
maintain a contract, with copies to Lessor, in customary form and substance 
for and with a contractor specializing and experienced in the inspection, 
maintenance and service of the heating, air conditioning and ventilation 
system for the Premises. However, Lessor reserves the right, upon notice to 
Lessee, to procure and maintain the contract for the heating, air 
conditioning and ventilating systems and if Lessor so elects, Lessee shall 
reimburse Lessor, upon demand, for the cost thereof.

         (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 
(Damage or Destruction) and 14 (Condemnation), Lessor, subject to 
reimbursement pursuant to Paragraph 4.2, shall keep in good order, condition 
and repair the foundations, exterior walls, structural condition of interior 
bearing walls, exterior roof, fire sprinkler and/or standpipe or hose (if 
located in the Common Areas) or other automatic fire extinguishing system 
including fire alarm and/or smoke


                                       -3-





detection systems and equipment, fire hydrants, parking lots, walkways, 
parkways, driveways, landscaping, fences, signs and utility systems serving 
the Common Areas and all parts thereof, as well as providing 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 nor 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 walks, 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.

         (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 and 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. Lessee 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 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 of 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.  INSURANCE; INDEMNITY

    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 pro-rated 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 insureds) 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 an occurrence 
basis providing single unit coverage in an amount not less than $2,000,000 
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 Lender(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 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 of 
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, 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

                                       4


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 cancellable 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 or 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 or 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 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 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 than 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) of 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 not 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 cost 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 or 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 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 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 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 expires. 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 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

                                       5


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 Substance 
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 
extent 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 Leesor 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.

     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 Alternations 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 AND 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 twenty-five percent (25%) or more of the voting control of Lessee shall 
constitute a change in control for this purpose.* REFER TO PARAGRAPH 59 BELOW.

           (c) The involvement of Lessee or its assets in any transaction, or 
series of transactions (by way of merger, sale, acquisition, financing, 
refinancing, transfer, leveraged buy-out or otherwise), whether or not a 
formal assignment or hypothecation of this Lease or Lessee's assets occurs, 
which results or will result in a reduction of the Net Worth of Lessee, as 
hereinafter defined, by an amount equal to or greater than twenty-five 
percent (25%) of such Net Worth of Lessee as it was represented to Lessor at 
the time of full execution and delivery of this Lease or at the time of the 
most recent assignment to which Lessor has consented, or as it exists 
immediately prior to said transaction or transactions constituting such 
reduction, at whichever time said Net Worth of Lessee was or is greater, 
shall be considered an assignment of this Lease by Lessee to which Lessor may 
reasonably withhold its consent. "Net Worth of Lessee" for purposes of this 
Lease shall be the net worth of Lessee (excluding any Guarantors) established 
under generally accepted accounting principles consistently applied.

           (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 any 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 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 reminder 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) after 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 by 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 but 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.

                                                             Initials
                                                                     ----------

                                                                     ----------

                                    -6-



           (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 two (2) 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 or any other assignment of such sublease 
to Lessor, nor by reason of the collection of the rents from a sublease, 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, to pay to 
Lessor the rents and other charges due and to become due under the sublease. 
Sublessee shall rely upon any such statement and request from Lessor 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 of such sublessor 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 any part of the Premises without Lessor's prior 
written consent.

           (e) Lessor shall deliver a copy of any notice of Default of 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), $350.00 is a reasonable minimum sum per such occurrence 
for legal services and costs in the preparation and service 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 applicable grace period, and shall entitle Lessor to 
pursue the remedies set forth in Paragraphs 13.2 and/or 13.3:

           (a) 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 
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 any 
such failure continues for a period of ten (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 Lesse'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:

           (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 the unpaid rent which had been earned at the time 
of termination; (ii) the worth at the time of 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 attorney's 
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 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 statute 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 become 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 hereafter available to Lessor 
under the laws or judicial decisions of the state wherein the Premises are 
located.

                                                             Initials
                                                                     ----------

                                                                    ----------



                                   -7-



          (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 cure 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 this
Paragraph 13.3 unless specifically so stated in writing by Lessor at the time of
such acceptance.

     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 within ten (10) days after such
amount shall be 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. *REFER TO PARAGRAPH 52 BELOW.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this 
Lease unless Lessor falls 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 
within 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, within 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.  BROKERS' FEES.

     15.1 PROCURING CAUSE.* The Broker(s) named in Paragraph 1.10 is/are the
procuring cause of this Lease. *REFER TO PARAGRAPH 55 BELOW.

     DELETE PARAGRAPH 15.3

     15.4 REPRESENTATIONS AND WARRANTIES. Lessee and Lessor each represent and
warrant to the other that it has had no dealings with any person, firm, 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 fees 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 for 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 Lease, 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 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. Either Party may 
be written notice to the other specify a different address for 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

                                                                Initials:       
                                                                          ------

                                                                          ------

                                       -8-



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 be deemed served or
delivered upon telephone or facsimile confirmation of receipt of the
transmission thereof, provided a copy is also delivered via delivery of mail. If
notice is received on a Saturday or a Sunday or a legal 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 
subsequent or similar act by Lessee, or be construed as the basis of an 
estoppel to enforce the provision or 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, with such statements and/or conditions shall 
be of no force or effect whatsoever unless specifically agreed to 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 term 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 twenty-five percent (125%) 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 
at 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.

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 renewals,
modifications, consolidations, replacements 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 or 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 of 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 or 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 reasonable 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 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 reasonable 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 two hundred seventy (270) 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.

33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, 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. Lessor's actual reasonable 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 matter 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
the Lessee under this Lease if any such Guarantor fails or refuses, upon
reasonable request by Lessor to give: (a) evidence of the due execution of the
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.


                                                                Initials:       
                                                                          ------

                                                                          ------

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 lease 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 Lease or separately or apart therefrom, and no Option may be separated 
from this Lease in any manner, by reservation or otherwise.

     39.3  MULTIPLE OPTIONS.  In the event that Lessee has any multiple 
Options to extend or renew this Lease, a letter option cannot be exercised 
unless the prior Options to extend or renew this Lease have been validly 
exercised.

     39.4  EFFECT OF DEFAULT ON OPTIONS.

     (a)  Lessees shall have no right to exercise an Option, notwithstanding 
any provision in the grant of Option to the contrary: (1) during the period 
commencing with the giving of any notice of Default under Paragraph 13.1 and 
continuing until the noticed Default is cured, or (ii) during the period of 
time any monetary obligation due Lessor from Lessee is unpaid (without regard 
to whether notice thereof is given Lessee), or (iii) during the time Lessee 
is in Breach of this Lease, or (iv) in the event that Lessor has given to 
Lessee three (3) or more notices of separate Defaults under Paragraph 13.1 
during the twelve (12) month period immediately preceding the exercise of the 
Option, whether or not the Defaults are cured.

     (b)  The period of time within which an Option may be exercised shall 
not be extended or enlarged by reason of Lessee's inability to exercise an 
Option because of the provisions of Paragraph 39.4(a).

     (c)  All rights of Lessee under the provisions of an Option shall 
terminate and be of no further force or effect, notwithstanding Lessee's due 
and timely exercise of the Option. If, after such exercise and during the 
term of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation 
of Lessee for a period of thirty (30) days after such obligation becomes due 
(without any necessity of Lessor to give notice thereof to Lessee); or (ii) 
Lessor gives to Lessee three (3) or more notices of separate Defaults under 
Paragraph 13.1 during any twelve (12) month period, whether or not the 
Defaults are cured, or (iii) if Lessee commits a Breach of this Lease.

40.  RULES AND REGULATIONS.  Lessee agrees that it will abide by, and keep 
and observe all reasonable rules and regulations ("Rules and Regulations") 
which Lessor may make from time to time for the management, safety, care, and 
cleanliness of the grounds, the parking and unloading of vehicles and the 
preservation of good order, as well as for the convenience of other occupants 
or tenants of the Building and the Industrial Center and their invitees.

41.  SECURITY MEASURES.  Lessee hereby acknowledges that the rental payable 
to Lessor hereunder does not include the cost of guard service or other 
security measures, and that Lessor shall have no obligation whatsoever to 
provide same. Lessee assumes all responsibility for the protection of the 
Premises, Lessee, its agents and invitees and their property from the acts of 
third parties.

42.  RESERVATIONS.  Lessor reserves the right, from time to time, to grant, 
without the consent or joinder of Lessee, such easements, rights of way, 
utility raceways, and dedications that Lessor deems necessary, and to cause 
the recordation of parcel maps and restrictions, so long as such easements, 
rights of way, utility raceways, dedications, maps and restrictions do not 
reasonably interfere with the use of the Premises by Lessee. Lessee agrees 
to sign any documents reasonably requested by Lessor to effectuate any such 
easement rights, dedication, map or restrictions.

43.  PERFORMANCE UNDER PROTEST.  If at any time a dispute shall arise as to 
any amount or sum of money to be paid by one Party to the other under the 
provisions hereof, the Party against whom the obligation to pay the money is 
asserted shall have the right to make payment "under protest" and such 
payment shall not be regarded as a voluntary payment and there shall survive 
the right on the part of said Party to institute suit for recovery of such 
sum. If it shall be adjudged that there was no legal obligation on the part 
of said Party to pay such sum or any part thereof, said Party shall be 
entitled to recover such sum or so much thereof as it was not legally 
required to pay under the provisions of this Lease.

44.  AUTHORITY.  If either Party hereto is a corporation, trust, or general or 
limited partnership, each individual executing this Lease on behalf of such 
entity represents and warrants that he or she is duly authorized to execute 
and deliver this Lease on its behalf. If Lessee is a corporation, trust or 
partnership, Lessee shall, within thirty (30) days after request by Lessor, 
deliver to Lessor evidence satisfactory to Lessor of such authority.

45.  CONFLICT.  Any conflict between the printed provisions of this Lease and 
the typewritten or handwritten provisions shall be controlled by the 
typewritten or handwritten provisions.

46.  OFFER.  Preparation of this Lease by either Lessor or Lessee or Lessor's 
agent or Lessee's agent and submission of same to Lessee or Lessor shall not 
be deemed an offer to lease. This Lease is not intended to be binding until 
executed and delivered by all Parties hereto.

47.  AMENDMENTS.  This Lease may be modified only in writing, signed by the 
parties in interest at the time of the modification. The Parties shall amend 
this Lease from time to time to reflect any adjustments that are made to the 
Base Rent or other rent payable under this Lease. As long as they do not 
materially change Lessee's obligations hereunder, Lessee agrees to make such 
reasonable non-monetary modifications to this Lease as may be reasonably 
required by an institutional insurance company or pension plan Lender in 
connection with the obtaining of normal financing or refinancing of the 
property of which the Premises are a part.

48.  MULTIPLE PARTIES.  Except as otherwise expressly provided herein, if 
more than one person or entity is named herein as either Lessor or Lessee, 
the obligations of such multiple persons shall be the joint and several 
responsibility of all persons or entities named herein as such Lessor or 
Lessee.

 ADDENDUM TO STANDARD INDUSTRIAL/COMMERCIAL MULTI TENANT LEASE - MODIFIED NET
              PARTIES: WILLOW ROAD ASSOCIATES, LLC (LESSOR), 
                 LIVINGSTON ENTERPRISES, INC. (LESSEE).
                             DATED: JANUARY 24, 1996


49. EARLY POSSESSION.  Lessee shall be granted possession of a portion of the 
Premises, as determined by Lessor in its sole and absolute discretion, on 
October 1, 1996, provided: (i) Lessee does not interfere with the 
construction of the improvements contemplated by this Lease or any seismic 
work that Lessor may elect to perform, nor cause a delay in such 
construction, and (ii) all governing authorities having jurisdiction over the 
Premises approve of Lessee's partial occupancy during the course of 
construction. In the event that Lessee's acts, changes, or omissions during 
such early possession causes a delay in completion of the improvements or 
seismic work, as determined by Lessor in its sole and absolute discretion, 
such delay shall not alter or affect the scheduled Commencement Date and 
Lessee shall pay Base Rent as of the Commencement Date even if the 
improvements and seismic work are not completed. In the event Lessee's early 
possession causes an increase in the cost to construct the improvements or 
seismic work, as determined by Lessor in its sole and absolute discretion, 
then Lessee shall pay Lessor on demand for such increase, regardless of the 
total cost of said improvements or seismic work. Notwithstanding anything to 
the contrary contained in this Lease, if partial possession is not tendered 
to Lessee on the scheduled Early Possession Date, the period free of the 
obligation to pay Base Rent shall terminate on the date prior to the 
Commencement Date and shall not extend for any period thereafter.

50. RENT INCREASE.  Commencing May 1, 1999 and continuing through October, 
2001, the monthly Base Rent shall be $52,000.00. Commencing November 1, 2001 
and continuing through the remainder of the Original Term, the monthly Base 
Rent shall be $55,500.00.

51. PARKING.  Notwithstanding anything to the contrary contained in paragraph 
2.6 above, Lessee shall not park nor permit to be parked any inoperative 
vehicles on any portion of the Common Areas.

52. LATE CHARGES.  In reference to paragraph 13.4 above, the ten (10) day time 
period for performance shall end at 4:00 PM Pacific Time on the tenth (10th) 
calendar day. If the ten (10) day time period for performance ends on a 
Saturday, Sunday, or federal, state, city or legal holiday, then such date 
for performance shall be extended to 4:00 PM Pacific Time on the following 
day which is not a Saturday, Sunday, or federal, state, city or legal 
holiday. Notwithstanding anything to the contrary contained in paragraph 13.4 
above or this paragraph 52, Lessor agrees to waive the late charge the first 
time only, AND FOR NO OTHER TIME, Lessee fails to pay rent or any other sum 
due from Lessee within the time period required in this Lease, provided 
Lessee delivers to Lessor said rent or other sum due within three days after 
being notified by Lessor that the rent or other sum due is late.

53. PETS.  Lessee shall not keep or permit to be kept any pets within the 
Premises, Common Areas, or Industrial Center at any time.

54. FINANCIAL STATEMENTS.  Lessee shall provide Lessor with additional 
financial statements and credit references as Lessor may require prior to the 
execution of this Lease.

55. CONFIDENTIALITY.  Lessee and Broker agree to keep every part of this Lease 
confidential and not to disclose nor advertise any of the terms and 
conditions of this Lease without the Lessor's prior written consent.

56. IMPROVEMENTS.  Immediately upon execution and delivery of this Lease, 
Lessor and Lessee agree to meet with Lessor's architect to plan alterations 
and improvements to the Premises. Lessor and Lessee agree to cooperate and 
work expeditiously in finalizing a floor plan within one month of the 
execution of this Lease. Commencing on the later of the Early Possession Date 
or the date which Lessor receives a building permit to construct the 
improvements, Lessor, at Lessor's expense, and subject to possible 
reimbursement below, shall begin the improvement work as indicated on the 
improvement plans. Lessor's cost for the improvements, including the cost of 
architectural and engineering, building permits, plan check, fees, fire 
protection, ADA compliance, and all other improvement-related costs requested 
by Lessee or required by any governing authority, excepting only the cost to 
repaint the Building, shall not exceed $200,000.00. In the event it is 
estimated that the cost shall exceed $200,000.00, then prior to the 
commencement of any work by Lessor and upon Lessor's demand, Lessee shall pay 
to Lessor that portion exceeding $200,000.00. Notwithstanding anything to the 
contrary contained above, Lessor, at Lessor's expense, shall repaint the 
exterior of the Building on or before December 31, 1996.

57. OPTION TO EXTEND.  Subject to the provisions contained in paragraph 39 
above, Lessee shall have the right, at its option, to extend the term of this 
Lease for a period of five (5) years commencing November 1, 2004 (the 
"Extension Term"). If Lessee elects to extend this Lease pursuant to this 
paragraph 57, Lessee shall give unequivocal written notice ("Exercise 
Notice") of its exercise to Lessor not less than two hundred seventy (270) 
days prior to the Expiration Date of the Original Term. Lessee's failure to 
give the Exercise Notice in a timely manner shall be deemed a waiver of 
Lessee's right to extend. The terms, covenants and conditions applicable to 
the Extension Term shall be the same terms, covenants and conditions of this 
Lease except that (1) Lessee shall not be entitled to any further option to 
extend for any period after the Extension Term, and (2) the Base Rent for the 
Premises shall be increased as provided in this paragraph 57.

DETERMINATION OF BASE RENT DURING THE EXTENSION TERM:

     (i)  AGREEMENT ON RENT.  Lessor and Lessee shall have sixty (60) days 
after Lessor receives the Exercise Notice in which to agree on the Base Rent 
during the Extension Term, which shall be the fair market rental value of the 
Premises during the Extension Term. In determining the fair market rental 
value of the Premises during the Extension Term, consideration shall be given 
to the uses of the premises permitted under this Lease, the quality, size, 
design and location of the Premises, and the rental value of comparable space 
located the Pleasanton area with similar quality improvements to the 
improvements in existence on the date of the extension. In no event shall the 
Base Rent for the Extension Term be less than the Base Rent last payable 
under this Lease during the Original Term. If Lessor and Lessee agree on the 
Base Rent for the Extension Term during the sixty (60) day period, they shall 
immediately execute an amendment to this Lease stating the Base Rent.



     (ii)  SELECTION OF APPRAISERS.  If Lessor and Lessee are unable to agree 
on the Base Rent for the Extension Term within the sixty (60) day period, 
then within ten (10) days after the expiration of the sixty (60) day period, 
Lessor and Lessee each, at its cost and by giving notice to the other party, 
shall appoint a competent disinterested real estate appraiser with at least 
five (5) years' full time commercial appraisal experience in the geographical 
area of the Building to appraise and set the Base Rent during the Extension 
Term. If either Lessor or Lessee does not appoint an appraiser within ten 
(10) days after the other party has given notice of the name of its 
appraiser, the single appraiser appointed shall be the sole appraiser and shall
set the Base Rent during the Extension Term. If two (2) appraisers are 
appointed by Lessor and Lessee as stated in this paragraph, they shall meet 
promptly and attempt to set the Base Rent during the Extension Term. If two 
(2) appraisers are unable to agree within thirty (30) days after the second 
appraiser has been appointed, they shall attempt to select a third appraiser 
meeting the qualifications stated in this paragraph within ten (10) days 
after the last day the two (2) appraisers are given to set the Base Rent. 
If they are unable to agree on the third appraiser, either Lessor or Lessee, by
giving ten (10) days' notice to the other party, can apply to the then 
president of the real estate board of the county in which the Building is 
located, or to the Presiding Judge of the Superior Court of the county in which
the Building is located, for the selection of a third appraiser who meets the 
qualifications stated in this paragraph. Lessor and Lessee each shall bear 
one-half (1/2) of the cost of appointing the third appraiser and of paying 
the third appraiser's fee. The third appraiser, however selected, shall be a 
person who has not previously acted in any capacity for either Lessor or 
Lessee.

     (iii)  VALUE DETERMINED BY THREE (3) APPRAISERS.  Within thirty (30) days 
after the selection of the third appraiser, a majority of the appraisers 
shall set the Base Rent for the Extension Term. If a majority of the 
appraisers is unable to set the Base Rent within the stipulated period of 
time, Lessor's appraiser shall arrange for simultaneous exchange of written 
appraisals from each of the appraisers and the three (3) appraisals shall be 
added together and their total divided by three (3); the resulting quotient 
shall be the Base Rent for the Premises during the Extension Term. If, 
however, the low appraisal and/or high appraisal are/is more than ten percent 
(10%) lower and/or higher than the middle appraisal, the low appraisal and/or 
the high appraisal shall be disregarded. If only one (1) appraisal is 
disregarded, the remain two (2) appraisals shall be added together and their 
total divided by two (2); the resulting quotient shall be the Base Rent for 
the Premises during the Extension Term. If both the low appraisal and the 
high appraisal are disregarded as stated this paragraph, the middle appraisal 
shall be the Base Rent for the Premises during the Extension Term.

     (iv)  NOTICE TO LESSOR AND LESSEE.  After the Base Rent for the Extension 
Term has been set, the appraisers shall immediately notify Lessor and Lessee, 
and Lessor and Lessee shall immediately execute an amendment to this Lease 
stating the Base Rent.

58.  HAZARDOUS SUBSTANCES.  Lessee acknowledges that Lessor has delivered to 
Lessee a copy of that certain Environmental Site Assessment dated September 
22, 1995 and Subsurface Investigation Report dated October 11, 1995, prepared 
by AllWest Environmental, Inc. (collectively, "Environmental Reports"). The 
Environmental Reports indicate the presence of trace amounts of a Hazardous 
Substance in the groundwater beneath the Building ("Existing Hazardous 
Substance"). Lessor shall be responsible for any investigation or remediation 
of the Existing Hazardous Substance required by any applicable governmental 
agency having jurisdiction and Lessee shall not be required to pay any costs 
in connection with any such investigation or remediation. Nothing contained 
herein shall absolve Lessee from any responsibility for Hazardous Substances 
used, generated, stored, disposed, released or transported by Lessee on or 
from the Industrial Center.

59.  ASSIGNMENT AND SUBLETTING.  Notwithstanding anything to the contrary 
contained in paragraph 12.1(b) above, the transfer, on a cumulative basis, of 
fifty (50%) percent or more of the voting control of Lessee shall constitute 
a change in control for purposes of this Lease, EXCEPT, in the event Lessee 
becomes a publically traded company through an initial and subsequent public 
offerings AND Steve Willens remains as President of Lessee, then for purposes 
of this Lease, the transfer, on a cumulative basis, of seventy-five (75%) 
percent or more of the voting control of Lessee shall constitute a change in 
control.
