given within six (6) months following the Commencement Date and setting forth
with specificity the nature and extent of such non-compliance, take such
action, at Lessor's expense, as may be reasonable or appropriate to rectify

Common Areas as they exist from time to time, subject to any rights, powers,
and privileges reserved by Lessor under the terms hereof or under the terms
of any rules and regulations or restrictions governing the use of the
Industrial Center. Under no circumstances shall the right herein granted to
use the Common Areas be deemed to include the right to store any property,
temporarily or permanently, in the Common Areas. Any such storage shall be
permitted only by the prior written consent of Lessor or Lessor's designated
agent, which consent may be revoked at any time. In the event that any
unauthorized storage shall occur then Lessor shall have the right, without

person(s) as Lessor may appoint shall have the exclusive control and
management of the Common Areas and shall have the right, from time to time,

and conform to all such Rules and Regulations, and to cause its employees,
suppliers, shippers, customers, contractors and invitees to so abide and

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

         3.2  EARLY POSSESSION. If an Early Possession Date is specified in
Paragraph 1.4 and if Lessee totally or partially occupies the Premises after
the Early Possession Date but prior to the Commencement Date, the obligation
to pay Base Rent shall be abated for the period of such early occupancy. All
other terms of this Lease, however, (including but not limited to the
obligations to pay Lessee's Share of Common Area Operating Expenses and to
carry the insurance required by Paragraph 8) shall be in effect during such
period. Any such early possession shall not affect nor advance the Expiration
Date of the Original Term.

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

4.   RENT.

         4.1  BASE RENT. Lessee shall pay Base Rent and other rent or
charges, as the same may be adjusted from time to time, to Lessor in lawful
money of the United States, without offset or deduction, on or before the day
on which it is due under the terms of this Lease. Base Rent and all other
rent and charges for any period during the term hereof which is for less than
one full month shall be prorated based upon the actual number of days of the
month involved. Payment of Base Rent and other charges shall be made to
Lessor at its address stated herein or to such other persons or at such other
addresses as Lessor may from time to time designate in writing to Lessee.

         4.2  COMMON AREA OPERATING EXPENSES. Lessee shall pay to Lessor

specified in Paragraph 1.6(b)) of all Common Area Operating Expenses, as

accordance with the following provisions:

                  (a)  "Common Area Operating Expenses" are defined, for

                           (viii)  Any other services to be provided by
Lessor that are stated elsewhere in this Lease to be a Common Area Operating
Expense.

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

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

                  (d)  Lessee's Share of Common Area Operating Expenses shall
be payable by Lessee within ten (10) days after a reasonably detailed
statement of actual expenses is presented to Lessee by Lessor. At Lessor's
option, however, an amount may be estimated by Lessor from time to time of
Lessee's Share of Annual Common Area Operating Expenses and the same shall be
payable monthly or quarterly, as Lessor shall designate, during each 12 month
period of the Lease term, on the same day as the Base Rent is due hereunder.
Lessor shall deliver to Lessee within sixty (60) days after the expiration of
each calendar year a reasonably detailed statement showing Lessee's Share of
the actual Common Area Operating Expenses incurred during the preceding year.

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 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.
Lessor shall not be required to keep all or any part of the Security Deposit
separate from its general accounts. Lessor shall at the expiration or earlier
termination of the term hereof and after Lessee has vacated the Premises,
return to Lessee (or, at Lessor's option, to the last assignee, if any, of
Lessee's interest herein) that portion of the Security Deposit not used or
applied by Lessor. Unless otherwise expressly agreed in writing by Lessor, no
part of the Security Deposit shall be considered to be held in trust, to bear
interest or other increment for its use, or to be prepayment for any monies
to be paid by Lessee under this Lease.

6.   USE.

         6.1  PERMITTED USE.

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

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

         6.2  HAZARDOUS SUBSTANCES.

                  (a)  REPORTABLE USES REQUIRE CONSENT. The term "Hazardous
Substance" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of
existence, use, manufacture, disposal, transportation, spill, release or
effect, either by itself or in combination with other materials expected to
be on the Premises, is either: (i) potentially injurious to the public
health, safety or welfare, the environment, or the Premises; (ii) regulated
or monitored by any governmental authority; or (iii) a basis for potential
liability of Lessor to any governmental agency or third party under any
applicable statute or common law theory. Hazardous Substance shall include,
but not be limited to, hydrocarbons, petroleum, gasoline, crude oil or any
products or by-products thereof, Lessee shall not engage in any activity in
or about the Premises which constitutes a Reportable Use (as hereinafter
defined) of Hazardous Substances without the express prior written consent of
Lessor and compliance in a timely manner (at Lessee's sole cost and expense)
with all Applicable Requirements (as defined in Paragraph 6.3). "Reportable
Use" shall mean (i) the installation or use of any above or below ground
storage tank, (ii) the generation, possession, storage, use, transportation,
or disposal of a Hazardous Substance that requires a permit from, or with
respect to which a report, notice, registration or business plan is required
to be filed with, any governmental authority, and (iii) the presence in, on
or about the Premises of a Hazardous Substance with respect to which any
Applicable Laws require that a notice be given to persons entering or
occupying the Premises or neighboring properties. Notwithstanding the
foregoing, Lessee may without Lessor's prior consent, 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).

                  (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 by Lessor in writing at the time of such agreement.

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

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

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

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 report (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),

facilities specifically serving the Premises, such as plumbing, heating, air
conditioning, ventilating, electrical, lighting facilities, boilers, fired or
unfired pressure vessels, fire hose connections if within the Premises,
fixtures, interior walls, interior surfaces of exterior walls, ceilings,
floors, windows, doors, plate glass, and skylights, but excluding any items
which are the responsibility of Lessor pursuant to Paragraph 7.2 below.
Lessee, in keeping the Premises in good order, condition and repair, shall
exercise and perform good maintenance practices. Lessee's obligations shall
include restorations, replacements 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

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 walls, or changing or interfering with the
fire sprinkler or fire detection systems and the cumulative cost thereof
during the term of this Lease as extended does not exceed $2,500.00.

                  (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. Lessor may, (but without obligation to do so)
condition its consent to any requested Alteration or Utility Installation
that costs $2,500.00 or more upon Lessee's providing Lessor with a lien and
completion bond in an amount equal to one and one-half times the estimated
cost of such Alteration or Utility Installation.

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

         8.2  LIABILITY INSURANCE.

                  (a)  CARRIED BY LESSEE. Lessee shall obtain and keep in
force during the term of this Lease a Commercial General Liability policy of
insurance protecting Lessee. Lessor and any Lender(s) whose names have been
provided to Lessee in writing (as additional 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 limit coverage in an amount not less than $1,000,000
per occurrence with an "Additional Insured-Managers or Lessors of Premises"
endorsement and contain the "Amendment of the Pollution Exclusion"
endorsement for damage caused by heat smoke or fumes from a hostile fire. The
policy shall not contain any intra-insured exclusions as between insured
persons or organizations, but shall include coverage for liability assumed
under this Lease as an "Insured contract" for the performance of Lessee's
indemnity obligations under this Lease. The limits of said insurance required
by this Lease or as carried by Lessee shall not, however, limit the liability
of Lessee nor relieve Lessee of any obligation hereunder. All insurance to be
carried by Lessee shall be primary to and not contributory with any similar
insurance carried by Lessor, whose insurance shall be considered excess
insurance only.

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

         8.3  PROPERTY INSURANCE-BUILDING, IMPROVEMENTS AND RENTAL VALUE.

                  (a)  BUILDING AND IMPROVEMENTS. Lessor shall obtain and
keep in force during the term of this Lease a policy or policies in the name
of Lessor, with loss payable to Lessor and to any Lender(s), insuring against
loss or damage to the Premises. Such insurance shall be for full replacement
cost, as the same shall exist from time to time, or the amount required by
any 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 including, if available at commercially reasonable costs, the
perils of flood and/or earthquake, including coverage for any additional
costs resulting from debris removal and reasonable amounts of coverage for
the enforcement of any 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 evaluation
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 in 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
Lesser-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 rating as may be required by a Lender as
set forth in the most current issue of "Best's Insurance Guide." Lessee shall
not do or permit to be done anything which shall invalidate the insurance
policies referred to in

this Paragraph 8. Lessee shall cause to be delivered to Lessor, within seven
(7) days after the earlier of the Early Possession Date or the Commencement
Date, certified copies of, or certificates evidencing the existence and
amounts of, the insurance required under Paragraphs 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 renewal or "insurance binders" evidencing renewal thereof, or Lessor may
order such insurance and charge the cost hereof 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 gross 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 define 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 Lessee 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 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 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 the limits of coverage 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, unless
due to Lessor's gross negligence or willful misconduct.

                  (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

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 or Lessor's
desire 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 Lessor and so much of Lessee's Security Deposit as
has not been, or is not then required to be, used by Lessor under the terms
of this Lease.

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

10.  REAL PROPERTY TAXES.

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

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

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

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

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

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

         12.3  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 transfer 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
obligation 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 sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such
sublessee under such Sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor
stating that a Breach exists in the performance of Lessee's obligations under
this Lease to pay to Lessor the rents and other charges due and to become due
under the sublease. Sublease 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
or Breach by Lessee to the sublessee, who shall have the right to cure the
Default of Lessee within the grace period, if any, specified in such notice.
The sublessee shall have a right of reimbursement and offset from and against
lessee for any such Defaults cured by the sublessee.

13.  DEFAULT; BREACH; REMEDIES.

         13.1  DEFAULT; BREACH. Lessor and Lessee agree that if an attorney
is consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $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 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 Lessee's
interest in this Lease, where possession is not restored to Lessee within
thirty (30) days; or (iv) the attachment, execution or other judicial seizure
of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within
thirty (30) days; provided, however, in the event that any provision of this
Subparagraph 13.1(e) is contrary to any applicable law, such provision shall
be of no force or effect, and shall not affect the validity of the remaining
provisions.

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

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

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

                  (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 of which the unpaid rent for the balance of
the term after the time of award exceeds the amount of such rental loss that
the Lessee proves could be reasonably avoided; and (iv) any other amount
necessary to compensate Lessor for all the detriment proximately caused by
the Lessee's failure to perform its obligations under this Lease or which in
the ordinary course of things would be likely to result therefrom, including
but not limited to the cost of recovering possession of the Premises,
expenses of reletting, including necessary renovation and alteration of the
Premises, reasonable attorneys' fees, and that portion of any leasing
commission paid by Lessor in connection with this Lease applicable to the
unexpired term of this Lease. The worth at the time of 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 suite
for such rent and/or damages. If a notice and grace period required under
Subparagraph 13.1(b), (c) or (d) was not previously given, a notice to pay
rent or quit, or to perform or quit, as the case may be, given to Lessee
under any statute authorizing the forfeiture of leases for unlawful detainer
shall also constitute the applicable notice for grace period purposes
required by Subparagraph 13.1(b), (c) or (d). In such case, the applicable
grace period under the unlawful detainer statue shall run currently 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 entitle Lessor to the remedies
provided for in this Lease and/or by said statute.

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

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

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

         13.3  INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by
Lessor for free or abated rent or other charges applicable to the Premises,
or for the giving or paying by Lessor to or for Lessee of any cash or other
bonus, inducement or consideration for Lessee's entering into this Lease, all
of which concessions are hereinafter referred to as "Inducement Provisions"
shall be deemed conditions under 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 where or not collected for three (3) consecutive
installments of Base Rent, then notwithstanding Paragraph 4.1 or any other
provision of this Lease to the contrary, Base Rent shall at Lessor's option,
become due and payable quarterly in advance.

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

         15.1  PROCURING CAUSE. The Broker(s) named in Paragraph 1.10 is/are
the procuring cause of this Lease.

         15.2  ADDITIONAL TERMS. Unless Lessor and Broker(s) have otherwise

defined in Paragraph 39.1) granted under this Lease or any Option
subsequently granted, or (b) if Lessee acquires any rights to the Premises or
other premises in which Lessor has an interest, or (c) if Lessee remains in
possession of the Premises with the consent of Lessor after the expiration of
the term of this Lease after having failed to exercise an Option, or (d) if
said Brokers are the procuring cause of any other lease or sale entered into
between the Parties pertaining to the Premises and/or any adjacent property
in which Lessor has an interest, or (e) if Base Rent is increased, whether by
agreement or operation of an escalation clause herein, then as to any of said
transactions, Lessor shall pay said Broker(s) a fee in accordance with the
schedule of said Broker(s) in effect at the time of the execution of this
Lease.

         15.3  ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of Lessor's
interest in this Lease, whether such transfer is by agreement or by operation
of law, shall be deemed to have assumed Lessor's obligation under this
Paragraph 15. Each Broker shall be an intended third party beneficiary of the
provisions of Paragraph 1.10 and of this Paragraph 15 to the extent of its
interest in any commission arising from this Lease and may enforce that right
directly against Lessor and its successors.

         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 fee in connection with said transaction, Lessee and Lessor do each
hereby agree to indemnify, protect, defend and hold the other harmless from
and against liability for compensation or charges which may be claimed by any
such unnamed broker, finder or other similar party by reason of any dealings
or actions of the indemnifying Party, including any costs, expenses, and/or
attorneys' fees reasonably incurred with respect thereto.

16.  TENANCY AND FINANCIAL STATEMENTS.

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

         16.2  FINANCIAL STATEMENT. If Lessor desires to finance, refinance,
or sell the Premises or the Building, or any part thereof, Lessee and all
Guarantors shall deliver to any potential lender or purchaser designated by
Lessor such financial statements of Lessee and such Guarantors as may be
reasonably required by such lender or purchaser, including but not limited to
Lessee's financial statements 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 mail of notice purposes. Either Party may by
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

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

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, 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, which 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.

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 without the written consent of Lessor then the Base Rent payable
from and after the time of the expiration or earlier termination of this
Lease shall be increased to two hundred percent (200%) of the Base Rent
applicable during the month immediately receding such expiration or earlier
termination. Nothing contained herein shall be construed as a consent by
Lessor to any holder over the Lessee.

27.  CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, whenever possible, be cumulative with all other remedies
of 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' fees 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 of 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 one hundred eighty (180) days of the
term hereof place on or about the Premises any ordinary "For Lease" signs.
All such activities of Lessor shall be without abatement of rent or liability
to Lessee.

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's
consent to any act, assignment of this Lease or subletting of the Premises by
Lessee shall not constitute an acknowledgement that no Default or Breach 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.

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 of 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

            STANDARD INDUSTRIAL/COMMERCIAL SINGLE-TENANT LEASE - NET

--------------------------------------------------------------------------------


This Addendum One is made a part of the Standard Industrial/Commercial Single
-Tenant Lease - Modified Net ("Lease") dated as of June 18, 1999, by and
between 3355 Edison Partners, a California General Partnership, as Lessor,
and Homestead Technologies, Inc., a Delaware Corporation, as Lessee, for the
premises commonly known as 3375 Edison Way, Menlo Park, CA. If any conflicts
exist between the Lease and this Addendum, the terms of this Addendum shall
govern.

49.  TENANT IMPROVEMENT ALLOWANCE:

Lessor at its sole cost shall improve the premises per attached plans
Exhibits A & B and construction drawings. Said improvements shall include
$50,000.00 allowance for Voice and Data Cabling. In addition, if requested by
Lessee on or before September 1, 1999, Lessor shall provide up to $25,000.00
additional allowance towards Data Cabling. It is agreed and understood that
the Monthly Rent shall increase $10.40 for every $1,000.00 of the additional
allowance that is used at the request of Lessee.

50.  COMPLIANCE WITH AMERICANS WITH DISABILITIES ACT:

Lessee shall be responsible for the installation and cost of any and all
improvements, alterations or other work required on or to the premises or to
any other portion of the property and/or building of which the premises are a
part, required or reasonably necessary because of: (1) the use to which the
Premises or any portion thereof is put; (2) the use by a subtenant by reason
of assignment or sublease; or (3) both, including any improvements,
alterations or other work required under the Americans With Disabilities Act
of 1990. Compliance with the provisions of this Paragraph shall be a
condition of Lessor granting its consent to any assignment or lease of all or
a portion of this Lease and the Premises described in this Lease.

Broker makes no representation or warranty with respect to compliance or
noncompliance of the facility or any contemplated use with ADA requirements.
We recommend that you consult your attorney to determine if this act applies
to you and if so the requirements that must be met. The applicability of the
Act is a legal issue and we cannot give you legal advice on such matters.

51.  TOXIC CONTAMINATION DISCLOSURE:

Lessor and Lessee acknowledge that they have been advised that numerous
federal, state, and/or local laws, ordinances and regulations (hereinafter
referred to as the "Laws") affect the existence and removal, storage,
disposal, leakage of and contamination by materials designated as hazardous
or toxic (hereinafter referred to as the "Toxics"). Many materials, some
utilized in everyday business activities and property maintenance, are
designated as hazardous or toxic.

Some of the Laws require that Toxics be removed or cleaned up by landowners,
future landowners or former landowners without regard to whether the party
required to pay for "clean up" caused the contamination, owned the property
at the time the contamination occurred or even knew about the contamination.
Some items, such as asbestos or PCBs, which were legal when installed, now
are classified as Toxics, and are subject to removal requirements. Civil
lawsuits for damages resulting from Toxics may be filed by third parties in
certain circumstances.

Broker has recommended, and hereby recommends, that each of the parties have
competent professional environmental specialists review the Property and make
recommended test so that a reasonably informed assessment of these matters
can be made by each of the parties. Lessor and Lessee acknowledge that
neither Broker nor its agents or salespersons, have been retained to
investigate or arrange investigation by others, and have not made any
recommendations or representations with regard to the presence or absence of
Toxics on, in or beneath the Property. Lessor and Lessee agree that they will
rely only on persons who are experts in this field and will obtain such
expert advice so each of them will be as fully informed as possible with
regards to Toxics in entering into this Agreement.

52.  ANNUAL COST OF LIVING RENTAL ADJUSTMENTS:

The minimum monthly rent provided for in Rent and Base Rent Paragraphs of the
lease agreement shall be subject to adjustment at the commencement of the
second year of the term and each year thereafter (hereinafter referred to as
the "Adjustment Date") as follows:

The base for computing the adjustment is the Consumer Price Index for: All
Urban Consumers/Urban Wage Earners and Clerical Workers (base year 1967 =
100) for San Francisco/Oakland published by the United States Department of
Labor, Bureau of Labor Statistics (hereinafter referred to as the "Index"),
which is in effect on the date of the commencement of the term (hereinafter
referred to as the "Beginning Index"). The Index published most immediately
preceding the Adjustment Date in question (hereinafter referred to as the
"Extension Index") is to be used in determining the amount of the adjustment.
If the Extension Index has increased over the Beginning Index, the minimum
monthly rent for the following year shall be set by multiplying the minimum
monthly rent set forth in Rent Paragraphs by a fraction, the numerator of
which is the Extension Index and the denominator of which is the Beginning
Index.

In no event shall such rent increases be less than 4% of the rent in effect
for the preceding 12 month period nor more than 8% of said period's rent.

                                       1.

            STANDARD INDUSTRIAL/COMMERCIAL SINGLE-TENANT LEASE - NET

--------------------------------------------------------------------------------


On adjustment of the minimum monthly rent as provided in this Lease, the
parties shall immediately execute an amendment to this Lease stating the new
minimum monthly rent.

If the Index is changed so that the Base Year differs from that in effect
when the term commences, the Index shall be converted in accordance with the
conversion factor published by the United States Department of Labor, Bureau
of Labor Statistics. If the Index is discontinued or revised during the term,
such other government index or computation with which it is replaced shall be
used in order to obtain substantially the same result as would be obtained if
the Index had not been discontinued or revised.

53.

The parties acknowledge that Soroush Kaboli is a licensed real estate broker
acting on behalf of the Lessor and is also a partner of the Lessor.

54.  ADDITIONAL SECURITY:

As additional security for Lessee's performance under the Lease, concurrently
with the execution hereof Tenant shall establish an interest bearing escrow
account ("Escrow") with a federally insured bank or savings and loan
association ("Bank"), held jointly in the name of Lessor and Tenant in the
amount of Five Hundred Thousand Dollars ($500,000.00) on the following terms
and conditions:

         54.1  RIGHT TO DRAW UPON ESCROW PROCEEDS. Lessor may (but shall not
be required to) draw from the Escrow from time to time, in singular or
partial draws upon Lessor's election in any such amount as may be necessary
to cure the then-existing default, up to the full amount thereof, and use the
proceeds therefrom (the "Escrow Proceeds") or any portion thereof to (i) cure
or remedy any Default of Tenant under this Lease; (ii) repair damage to the
Premises caused by Tenant; (iii) clean the Premises upon termination of this
Lease, (iv) reimburse Lessor for the payment of any amount which Lessor may
spend or be required to spend by reason of Lessee's Default, or (v)
compensate Lessor for any other loss or damage which Lessor may suffer by
reason of Lessee's Default, including without limitation all costs reasonably
incurred by Lessor in releasing the Premises; it being understood that any
use of the Escrow Proceeds shall not constitute a bar or defense to any of
Lessor's remedies set forth in this Lease. In such event and upon written
notice from Lessor to Tenant specifying the amount of the Escrow Proceeds so
utilized by Lessor, Tenant shall immediately restore the Escrow to the full
original amount required under this section. Lessee's failure to restore the
Escrow within ten (10) business days of Lessor's notice shall constitute a
Default hereunder.

         54.2  ESCROW INSTRUCTIONS. The instructions to the Bank ("Escrow
Instructions") shall provide (i) that Lessor may make partial and multiple
draws thereunder in any such amount as may be necessary to cure the
then-existing default, up to the full amount thereof, (ii) that Lessor may
draw upon the Escrow up to the full amount thereof, and the Bank will pay to
Lessor the amount of such draw upon receipt by the Bank of a sight draft
signed by Lessor, accompanied by a written certificate from Lessor that
Tenant is in Default under the Lease and that Tenant has failed to cure such
Default within fifteen (15) days after receipt by Tenant of Notice of Default
and that Lessor is otherwise entitled to draw upon the Escrow, and (iii)
that, in the event of Lessor's assignment or other transfer of its interest
in this Lease, the Escrow shall be freely assignable by and without recourse
to Lessor, to the assignee or transferee of such interest and the Bank will
confirm the same to Lessor and such assignee or transferee. The Escrow
Instructions shall also provide that the Escrow may not be released to Lessee
without the written consent of Lessor; but it shall be subject, however, to
release and/or reduction as set forth in Section 54.3 below. The Escrow
Instructions shall further provide that it will comply with instructions for
release an reduction of the Escrow only from the Lessor.

         54.3  RELEASE, REDUCTION, AND RESTORATION: The funds held in Escrow
shall be subject to release to Lessee and/or reduction as follows:

         a)  RELEASE. Within ten (10) days of the date that Lessee provides a
         certified statement to Lessor that it has received new capital in the
         minimum amount of Fifty Million and no/100 ($50,000,000.00) Dollars
         through an Initial Public Offering, Lessor shall execute written
         instructions to Bank releasing the Escrow in its entirety to Lessee.
         This right to release is in addition to, and not in lieu of, the right
         of reduction set forth below.

         b)  REDUCTION. Commencing on the third (3rd) anniversary of the
         Commencement Date, provided that Lessee is not and has not at any time
         been in Default beyond any applicable cure periods (except for monetary
         defaults), and annually on each anniversary thereafter so long as there
         is no occurrence of default, the amount of the Escrow shall be reduced
         by One Hundred Thousand and no/100 ($100,000.00) Dollars. Within five
         (5) days of each applicable anniversary, Lessor shall execute written
         instructions to Bank releasing the aforesaid sum to Lessee.

         c)  RESTORATION. Lessee shall provide quarterly financial reports to
         Lessor throughout the Term of the Lease. In the event that proceeds in
         the Escrow have previously been released pursuant to Section 54.3(b)
         above, and thereafter Lessee's Cash and Cash Equivalent Assets (as
         hereinafter defined) drop below Twenty Million and no/100
         ($20,000,000.00) Dollars, Lessee shall restore the Escrow to the
         original

                                       2.

            STANDARD INDUSTRIAL/COMMERCIAL SINGLE-TENANT LEASE - NET

--------------------------------------------------------------------------------


         amount. If Lessee defaults in any provision of the Lease beyond any
         applicable cure periods (except for monetary defaults),, regardless of
         whether such default is subsequently cured, Lessee shall restore the
         Escrow Account to its original amount and it shall remain at that
         amount for the term of the Lease including all options and periods of
         occupancy.

         d)  CASH AND CASH EQUIVALENT ASSETS. "Cash and Cash Equivalent Assets"
         shall mean the aggregate amount of the following, to the extent owned
         by Lessee free and clear of all loans, ninety day payables, and
         encumbrances (and excluding any Security Deposit or Escrow hereunder):
         (i) cash on hand; (ii) dollar demand deposits maintained in the United
         States with, or certificates of deposit having a maturity of 150 days
         or less issued by, any commercial bank or other financial institution
         acceptable to the Lessor; (iii) direct obligations of, or
         unconditionally guaranteed by, the United States and having a maturity
         of one hundred fifty (150) days or less; and (iv) readily marketable
         commercial paper having a maturity of one hundred fifty (150) days or
         less, issued by any corporation organized and existing under the laws
         of the United States or any state thereof or the District of Columbia
         and rated by any nationally recognized rating organization in the
         United States with the highest rating assigned by such organization.

         e)  RELEASE AT EXPIRATION OF TERM. On a date which is not more than
         thirty (30) days following the expiration of the Term (as it may be
         extended) or earlier termination of this Lease, the Escrow (as reduced
         pursuant to this section) shall be released to Lessee, less any amounts
         that Lessor reasonably estimates to be required to remedy any Defaults
         on the part of Lessee hereunder.

         f)  UCC FILING. Lessor shall be entitled to file a UCC-1 protecting its
         interest in the Escrow. Within five (5) days of any release or
         reduction of the Escrow in accordance with the terms of this Lease,
         Lessor shall file a revised UCC-1 or UCC-2, as applicable. Lessee shall
         execute such documents as reasonably requested by Lessor and required
         for any such filing.

         g)  STOCK WARRANTS. Upon execution, Lessee shall issue to Lessor or as
         Lessor directs, 12,000 warrants at a price of $2.727 per warrant.


55.      BASE RENT ADJUSTMENT:

In addition to the rental adjustment referred to in Paragraph 52 to this
Addendum, Base rent also shall be adjusted on the fifth and tenth
anniversaries of the Commencement Date (each an "Anniversary Date") to equal
the Fair Market Rental Value of the Premises on such Anniversary Date;
provided, however, that the Base Rent shall never be adjusted downward. Fair
Market Rental Value shall be determined as follows: Sixty (60) days prior to
each Anniversary Date, Lessor and Lessee shall meet and endeavor to agree
upon Fair Market Rental Value. If they are unable to so agree within thirty
(30) days, Lessor and Lessee shall each select a licensed real estate broker
who is active in the leasing or appraisal of similar space in the general
vicinity of the Building and is not affiliated with either Lessor or Lessee
(each a "Broker"). Each Broker shall thereupon determine the fair market
rental value of the Premises, and the Fair Market Rental Value, as ultimately
determined, shall not be greater than the larger determination nor less than
the smaller determination (the "Range"). The Brokers shall then select a
similarly qualified licensed real estate broker, who shall determine the Fair
Market Rental Value, which shall, in any event, be within the Range. Each
party shall pay the costs and fees of its respective Broker, and shall pay
half the costs and fees of the jointly appointed broker.

RIDER TO A.I.R.E.A. STANDARD INDUSTRIAL LEASE -- MULTI-TENANT (MODIFIED NET -
1993) DATED, FOR REFERENCE PURPOSES MAY 18, 1999 BY AND BETWEEN 3355 EDISON
PARTNERS ("LESSOR"), AND HOMESTEAD TECHNOLOGIES ("LESSEE").

This Rider is attached to and made a part of the above-referenced typeset
lease (the "Lease"). In the event of any conflict between the typeset portion
of the Lease and this Rider, the terms and provisions of this Rider shall
govern. If any addenda or amendments are also attached to the typeset portion
of the Lease, this Rider shall govern to the extent of any conflict between
the terms and provisions of this Rider and such addenda or amendments. All
references in the following paragraphs are to corresponding paragraphs of the
typeset portion of the Lease, except as otherwise expressly provided herein.

INSERT 1.2(a):  PREMISES.

         Lessor agrees that it will construct the Building in accordance with
the approved plans. Upon completion of the Building, either party shall have
the right, to be exercised within the first 30 days of the term, to cause the
rentable square feet of the Building to be measured by a certified architect
in accordance with Lessor's architect's methodology. In the event that the
measurement shows that the actual rentable square feet (calculated by
reference to the approved plans) is more or less than the 20,096 as
represented by Lessor, then Base Rent shall be adjusted proportionately. If
neither party exercises it right to measure the Building as set forth herein,
then the rentable square feet of the Building shall be deemed to be 20,096.

INSERT 1.2(b):  PARKING.

         Lessee's use of such parking shall be at no cost to Lessee during
the term of this Lease or any extensions thereof.

PAR. 2.2:  CONDITION.

         Notwithstanding anything to the contrary in Paragraph 2.2, should a
non-compliance with this warranty be of a latent nature, the time limitation
for delivery of notice shall be extended to nine (9) months, and Lessor shall
rectify such non-compliance, at Lessor's sole cost and expense, promptly
after receipt of written notice thereof.

PAR. 2.3:  COMPLIANCE WITH COVENANTS, RESTRICTIONS AND BUILDING CODES.

         If necessary to protect or preserve the rights of Lessee, Lessor
shall assign to Lessee the benefit of construction warranties respecting the
Building or the Premises.

PAR. 2.10:  COMMON AREAS - CHANGES.

         Notwithstanding the provisions of Paragraph 2.10, Landlord may
expand the Common Areas by the acquisition of adjacent land for purposes of
providing additional parking and landscaping for the benefit of the Premises.
In the event Landlord so expands the Common Area and such expansion is for
the benefit of other properties or tenants, then Lessee shall be required to
pay only its proportionate share of the costs of such expanded Common Area.
Lessor's rights pursuant to this Paragraph 2.10 shall be subject to the
condition that exercise of any of such rights shall not unreasonably
interfere with Lessee's use of the Premises, substantially change the size,
shape or location of the Common Areas as outlined on the attached Exhibit A
except as allowed in the previous sentence or decrease the number of parking
places allocated to Lessee pursuant to Paragraph 1.2(b).

PAR. 3.3:  DELAY IN POSSESSION.

         Notwithstanding anything to the contrary contained herein, if the
Premises is not delivered to Lessee within sixty (60) days after the
Commencement Date, and Lessee does not elect to terminate within the ten (10)
day period after such period, if a subsequent event occurs which further
delays the Commencement Date, fifteen (15) days after giving additional
notice to Lessor, Lessee shall be entitled to terminate this Lease. Such
election must be made by notice given to Lessor in writing within the twenty
(20) day period following the expiration of such fifteen (15) day notice
period.

PAR. 4.2(a):  COMMON AREA OPERATING EXPENSES.

                                       1.
<PAGE>

         Notwithstanding anything to the contrary contained in this Lease,
the following shall not be included within Common Area Operating Expenses:

                  Any depreciation on the Building or Property.

                  Costs of a capital nature involving replacement of the
roof, foundation, structural members, load-bearing walls, or building
systems; provided, however, that Lessee shall be responsible for replacement
of the HVAC system serving the Premises, if required during the first ten
(10) years of the Lease term. If replacement of the HVAC system is required
thereafter, the cost thereof shall be borne by Landlord, and Landlord shall
be entitled to include in Common Area Operating Expenses annually an amount
equal to one year's amortized cost of such replacement HVAC, amortized over
an anticipated ten year useful life. Such amortization shall be at ten
percent (10%).

                  Costs incurred due to Lessor's violation of any terms or
conditions of this Lease.

                  Overhead profit increments paid to Lessor's subsidiaries or
affiliates for management or other services on or to the building or for
supplies or other materials to the extent that the cost of the services,
supplies, or materials exceeds the cost that would have been paid had the
services, supplies, or materials been provided by unaffiliated parties on a
competitive basis.

                  All interest, loan fees, and other carrying costs related
to any mortgage or deed of trust or related to any capital item, and all
rental and other payable due under any ground or underlying lease, or any
lease for any equipment ordinarily considered to be of a capital nature
(except janitorial equipment which is not affixed to the Building.)

                  Costs of repairs and other work occasioned by fire,
windstorm, or other casualty of an insurable nature (but not including
deductibles paid by Landlord for insured losses). In no event, however, shall
Common Area Operating Costs include the amount of any deductibles paid with
respect to any loss covered by earthquake coverage, where such deductible
exceeds twenty-five thousand dollars.

                  Any costs, fines, or penalties incurred due to violations
by Lessor of any governmental rule or authority, this Lease or any other
lease in the Property, or due to Lessor's negligence or willful misconduct.

                  Management costs, to the extent they exceed 5% of Annual
Rent.

                  The cost of correcting any building code or other
violations which were violations prior to the Commencement Date.

                  The cost of containing, removing, or otherwise remediating
any contamination of the Property (including the underlying land and ground
water) by any toxic or hazardous materials (including, without limitation,
asbestos and "PCB's") where such contamination was not caused by Lessee or
any of its agents, employees, contractors or invitees.

PARAGRAPH 4.2(d):  COMMON AREA OPERATING EXPENSES.

Lessor shall keep complete and accurate records in accordance with good
bookkeeping and accounting practices regarding all Common Area Operating
Expenses. Lessee shall have the right to audit, at its sole cost and expense,
such records for each calendar year during the term of this Lease by
notifying Lessor within 120 days following the end of each such calendar year
and/or 120 days after Lessor has furnished Lessee a statement of such actual
expenses. If an audit (performed by a certified public accountant on behalf
of Lessee) reveals that Lessor has overcharged Lessee for common Area
Operating Expenses, Lessee shall so inform Lessor. If Lessee and Lessor do
not agree on such overcharge, then Lessee and Lessor agree to arbitrate the
amount (if any) of such overcharge and if Lessor is found to have overcharged
Lessee, Lessor shall refund the amount overcharged within ten days after such
determination has been made.

PARAGRAPH 6.2(d): LESSOR'S INDEMNITY. Paragraph 6.2(d) is hereby added, which
shall read in its entirety as follows:

                                       2.
<PAGE>

         Lessor warrants to Lessee that on the commencement of the term
hereof, to its actual knowledge, the Premises are free from contamination by
any preexisting Hazardous Substances (and for purposes of this Paragraph
6.2(d), the Premises shall be deemed to include the underlying soil and
ground water). Lessee shall in no event be responsible for any Hazardous
Substances which were preexisting or preexisting conditions on the Premises.
The provisions of this paragraph shall survive the termination of this Lease.

PAR. 7.2:  LESSOR'S OBLIGATIONS.

         Notwithstanding the provisions of Paragraph 7.2, if Lessor fails to
timely and reasonably perform its maintenance and repair obligations
hereunder, and, as a consequence, Lessee's use of the Premises is
substantially impaired, Lessee shall have the right to cause such repair or
maintenance to be performed at Lessor's expense and to deduct the costs
thereof, together with interest thereon at the highest rate permitted by law,
from the rent payable to Lessor.

PAR. 7.3(a):  DEFINITIONS; CONSENT REQUIRED.

         Notwithstanding the provisions of 7.3, Lessee shall be entitled to
make Alterations and Utility Installations in, on, under or about the
Premises, without the prior consent of Lessor, so long as the cost of each
such Alteration or Utility Installation (i) does not exceed the sum of
$15,000 (or the aggregate cost of such Alteration or Utility Installation
during any given one year period does not exceed $50,000), (ii) does not
effect any structural or exterior portions of the Building or adversely
effect the Building electrical, plumbing or HVAC systems, or (iii) does not
involve the removal or relocation of any walls. Lessee shall, however,
provide Lessor with fifteen (15) days prior advance written notice to enable
Lessor to post any desired notices of non-responsibility.

PAR. 7.4: OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION. Notwithstanding any
provision in this Lease to the contrary:

         (a)  Lessee shall not be required to remove (i) any improvements and
fixtures installed by Lessee in, on or about the Premises pursuant to
Lessee's repair obligation under this Lease, (ii) any of the initial Tenant
Improvements pursuant to Paragraph 50(A) hereof, or (iii) any Alterations or
Utility Installations for which Lessee has obtained Lessor's consent, unless
Lessor has indicated, at the time of granting such consent, that such removal
will be required.

         (b)  In addition to its personal property, equipment, and Trade
Fixtures, Lessee shall be entitled to remove any Lessee Owned Alterations and
Utility Installations (but not, in any case, any electrical or communications
cabling and any items agreed in advance by Lessor and Lessee to remain on the
Premises) at the expiration of the term, provided Lessee repairs all damage
caused by such removal.

PAR. 8.2(a) INSURANCE.

         Following the seventh year of the term, Lessor shall have the right
to require the amount of insurance coverage required to be carried by Lessee
hereunder to be adjusted to what is then a commercially reasonable and
customary amount.

PAR. 9:  DAMAGE OR DESTRUCTION.

         Notwithstanding anything to the contrary in Paragraph 9, if Lessee's
use of the Premises is substantially impaired for a period of more than 240
days after the date of casualty, Lessee shall have the right to terminate
this Lease by written notice to Lessor at any time thereafter until Lessee's
use of the Premises is substantially restored.

PAR. 10: REAL PROPERTY TAXES. Notwithstanding anything to the contrary in
Paragraph 10:

         All amounts paid by Lessee to Lessor in advance payment of any
year's Tax Increase in excess of taxes actually owed shall be paid by Lessor
to Lessee within five (5) days of reconciliation of such amounts by Lessor.

PAR. 12:  ASSIGNMENT AND SUBLETTING.

                                       3.
<PAGE>

         Lessee shall not sublet all or any portion of the Premises without
Lessor's prior written consent, which consent shall not be unreasonably
withheld, delayed or conditioned, subject to the terms of this Paragraph 12
and Paragraph 36.

         In the event Lessee desires to sublet all or any portion of the
Premises, Lessee shall so notify Lessor, specifying the portion of the
Premises proposed to be sublet, the terms of the proposed sublease and the
proposed subtenant. Lessee shall also provide Lessor with such other
information concerning the sublease, including the proposed use of the
Premises by such subtenant and the subtenant's financial status, as Lessor
may reasonably request. Upon receipt of such notice and information and upon
Lessee's request for consent to the sublease, Lessor shall have fifteen (15)
days to either consent to the proposed sublease or to terminate this Lease as
to the portion of the Premises proposed to be sublet (including the entire
Premises, if Lessee proposes to sublease the entire Premises). In the event
Lessor elects to so terminate this Lease as to a portion of the Premises,
Lessee shall be responsible for any costs of demising the portion of the
Premises as to which the Lease is terminating. In the event Lessor elects to
approve the proposed sublease, Lessor and Lessee shall share any Bonus Rent
received by Lessee pursuant to such sublease in the proportion of 70% for
Lessor and 30% for Lessee. For purposes of this Paragraph, "Bonus Rent" shall
mean the amount (if any) by which all consideration received by Lessee for
the sublease of the Premises exceeds the Rent payable hereunder, after first
deducting costs and fees paid by Lessee to sublease the Premises (but not the
costs to install Lessee's tenant improvements).

         Lessee may assign this Lease, or any portion thereof, without
Lessor's consent, by operation of law or otherwise, including to any entity
which controls, is controlled by, or is under common control with Lessee; to
any entity which results from a merger of, reorganization of, or
consolidation with Lessee; to any entity engaged in a joint venture with
Lessee; or to any entity which acquires substantially all of the stock or
assets of Lessee, as a going concern, with respect to the business that is
being conducted in the Premises (collectively, a "Permitted Transfer").
Lessee agrees to provide written notice to Lessor of any Permitted Transfer.

PAR. 13.2:  REMEDIES.

         Notwithstanding any other provisions of this Lease to the contrary,
Lessor's entry into the Premises for any purpose allowed by this Lease shall
be subject to Lessee's reasonable security requirements, including the
providing of reasonable notice, except in the event of emergency, in which
case, entry shall be allowed without prior notice or restriction.

PAR. 16.2  FINANCIAL STATEMENTS.

         Notwithstanding the foregoing, Lessee's obligations upon Lessor's
request, are limited to delivery of its currently existing financial
statements. In addition, Lessee agrees to provide Lessor with quarterly
unaudited financial statements and annual audited financial statements.

PAR. 25 RECORDING.

         Neither party shall record this Lease or a memorandum of lease with
the County Reorder.

PAR. 32:  LESSOR'S ACCESS.

         Notwithstanding the provisions of Paragraph 32, Lessor shall provide
Lessee with at least 24 hours' prior actual notice before entering the
Premises. In the event of an emergency, the determination of which shall
require Lessor to be reasonable, Lessor shall use its best efforts to provide
Lessee with notice reasonable in such situation. In the event of any entry by
Lessor onto the Premises, Lessor shall use its best efforts not to interfere
with the conduct of Lessee's business.

 PAR. 54:  ADDITIONAL SECURITY.

         The Escrow shall be in an interest bearing account with interest to
accrue for the benefit of Lessee and shall be paid out to Lessee quarterly.
Notwithstanding the foregoing, in the event Lessee is in default of its
obligations hereunder (after any applicable cure periods), such interest
shall be retained in the Escrow thereafter.

PAR. 55: LESSOR'S WARRANTY. Paragraph 55 is hereby added, reading in its
entirety as follows:

                                       4.
<PAGE>

         Lessor hereby warrants that it is the fee owner of the Premises, that
it has authority to enter into this Lease.

PAR. 56: LESSOR'S LIEN. Paragraph 56 is hereby added, reading in its entirety
as follows:

                  Notwithstanding anything herein to the contrary, Lessor
waives any and all rights, title and interest Lessor now has, or hereafter
may have, whether statutory or otherwise, to Lessee's inventory, equipment,
furnishings, trade fixtures, books and records, personal property, and tenant
improvements paid for by Lessee located at the Premises (singly and/or
collectively, the "Collateral"). Lessor acknowledges that Lessor has no lien,
right, claim, interest or title in or to the Collateral. Lessor further
agrees that Lessee have the right, at its discretion, to mortgage, pledge,
hypothecate or grant a security interest in the Collateral as security for
its obligations under any equipment lease or other financing arrangement
related to the conduct of Lessee's business at the Premises. Lessor further
agrees to execute and deliver within three (3) business days any UCC filing
statement or other documentation required to be executed by Lessor in
connection with any such lease or financing arrangement, and any real estate
consent or waiver forms submitted by any vendors, equipment lessors, chattel
mortgagees, or holders or owners of the Collateral setting forth, inter alia
that Lessor waives, in favor of such party any superior lien, claim, interest
or other right therein.

The Collateral shall not become the property of Lessor or a part of the
realty no matter how affixed to the Premises and may be removed by Lessee or
any Equipment Lessors at any time and from time to time during the entire
term of this Lease. Lessee shall promptly repair any damage caused by the
removal of such property, whether effected by Lessee or Equipment Lessors.

PAR. 57: ESTOPPEL CERTIFICATES.

         Each party shall, within ten (10) business days of receiving a
request from the other party, execute, acknowledge in recordable form, and
deliver to the other party or its designee a certificate stating, subject to
a specific statement of any applicable exceptions, that the Lease as amended
to date is in full force and effect, that the Lessee is paying Rent and other
charges on a current basis, and that to the best of the knowledge of the
certifying party, the other party has committed no uncured defaults and has
no offsets or claims. The certifying party may also be required to state the
date of commencement of payment of Rent, the Commencement Date, the
Termination Date, the Base Rent, the current Common Area Operating Expense
estimates, the status of any improvements required to be completed by Lessor,
the amount of any security deposit, and such other matters as may be
reasonably requested.
