terms, covenants and conditions set forth in this Lease.  Unless otherwise

not subject to revision whether or not the actual square footage is more or

     2.2  Condition.  Lessor shall deliver the Premises to Lessee clean and
          ---------
free of debris on the Commencement Date and warrants to Lessee that the
existing plumbing, electrical systems, fire sprinkler system, lighting, air
conditioning and heating systems and loading doors, and the roof, if any, in
the Premises, other than those constructed by Lessee, shall be in good
operating condition on the Commencement Date.  If a non-compliance with said
warranty exists as of the Commencement Date, Lessor shall, except as otherwise
provided in this Lease, promptly after receipt of written notice from Lessee
setting forth with specificity the nature and extent of such non-compliance,
rectify same at Lessor's expense.  If Lessee does not give Lessor written

Lessee at Lessee's sole cost and expense.

          ---------------------------------------------------------
warrants that any improvements (other than those constructed by Lessee or at

of the Commencement Date.  Said warranties shall not apply to any Alterations
or Utility Installations (defined in Paragraph 7.3(a)) made or to be made by
Lessee.  If the Premises do not comply with said warranties, Lessor shall,
except as otherwise provided in this Lease, promptly after receipt of written
notice from Lessee given within one (1) year 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 the non-compliance.

Vehicles other than Permitted Size Vehicles shall be parked and loaded or
unloaded as directed by Lessor in the Rules and Regulations (as defined in
Paragraph 40) issued by Lessor.  (Also see Paragraph 2.9.)  Landlord shall

contractors or invitees to be loaded, unloaded, or parked in areas other than
those designated by Lessor for such activities.

cost to Lessee, which cost shall be immediately payable upon demand by Lessor.

parking facilities required by Applicable Law, and in no event shall Lessor
oversubscribe parking.

          -----------------
and facilities outside the Premises and within the exterior boundary line of

Areas, 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 shall not be
unreasonably withheld or delayed.  In the event that any unauthorized storage
shall occur then Lessor shall have the right, upon one (1) business day's
notice, in addition to such other rights and remedies that it may have but in
accordance with Applicable Laws, to remove the property and charge the
reasonable cost to Lessee, which cost shall be immediately payable upon demand

amend and enforce reasonable Rules and Regulations with respect thereto in
accordance with Paragraph 39.  Lessee agrees to abide by and conform to all
such Rules and Regulations, and to cause its employees, suppliers, shippers,

3. Term.

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

     3.2  Early Possession.  If an Early Possession Date is specified in
          ----------------
Paragraph 1.4 and if Lessee totally or partially occupies the Premises after
the Early Possession Date but prior to the Commencement Date, the obligation to
pay Base Rent shall be abated for the period of such early occupancy.  All
other terms of this Lease, however, (including but 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.

     2.3  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 on July 1, 2001, Lessee may, at its option, by
notice in writing to Lessor, cancel this Lease, in which event the parties
shall be discharged from all obligations hereunder and Lessor shall promptly
return to Lessee the Security Deposit and any advance payment of Rent or other
related monies with respect to this Lease.  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.

     4.1  Base Rent.  Lessee shall pay Base Rent and other rent or charges 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 during

defined, during each calendar year of the term of this Lease, in accordance
with the following provisions:

          (a) "Common Area Operating Expenses" are defined, for purposes of
this Lease, as all costs incurred by Lessor relating to the ownership and
operation of the Industrial Center, including, but not limited to, the
following:

               (i)   The operation, repair and maintenance, in neat, clean,
good order and condition, of the following:

                                                                   Page 2 of 12

               (iii) Trash disposal, property management and security services.

               (iv)  Real Property Taxes (as defined in Paragraph 10.2) to be
paid by Lessor for the Building and the Common Areas under Paragraph 10 hereof.
(v) The cost of the premiums for the insurance policies maintained by Lessor
under Paragraph 8 hereof.

               (vi)  Any deductible portion of an insured loss concerning the
Building or the Common Areas not to exceed $10,000 per occurrence. (vii) 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.

          (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 Carrier 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 thirty (30) 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 of Lessee's Share of annual Common Area
Operating Expenses and the same shall be payable monthly, 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.  If Lessee's payments under this Paragraph
4.2(d) during said preceding year exceed Lessee's Share as indicated on said
statement, Lessee shall be promptly credited (or reimbursed, if the Lease has
expired) the amount of such over-payment against Lessee's Rent next becoming
due.  It 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 thirty (30) days after
delivery by Lessor to Lessee of said statement.

     5.  Security Deposit.  Lessee shall deposit with Lessor upon Lessee's
         ----------------
execution hereof the Security Deposit set forth in Paragraph 1.7 as security
for Lessee's faithful performance of Lessee's obligations under this Lease.  If
Lessee fails to pay Base Rent or other rent or charges due hereunder, or
otherwise Defaults under this Lease (as defined in Paragraph 13.1), Lessor may
use, apply or retain all or any portion of said Security Deposit for the
payment of any amount due Lessor or to reimburse or compensate Lessor for any
liability, cost, expense, loss or damage (including attorneys' fees) which
Lessor may suffer or incur by reason thereof.  If Lessor uses or applies all or
any portion of said Security Deposit, Lessee shall within ten (10) days after
written request therefore deposit monies with Lessor sufficient to restore said
Security Deposit to the full amount required by this Lease.  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 Lessee's request, to the last assignee, if any, of Lessee's interest
herein), that portion of the Security Deposit not used or applied by Lessor.
No part of the Security Deposit shall be considered to be hold 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 without Lessor's prior written
consent which Lessor shall not unreasonably withhold or delay.  Lessee shall
not use or permit the use of the Premises in a manner that is unlawful, creates
waste or a nuisance, or that unreasonably 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 adversely impact the structural integrity of the improvements on the
Premises or in the Building or the mechanical or electrical systems therein, 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
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, is either: (i)
potentially injurious to the public health, safety or welfare, the environment,
or the Premises; (ii) regulated or monitored by any governmental authority; or
(iii) a basis for potential liability of Lessor to any governmental agency or
third party under any applicable statute or common law theory.  Hazardous
Substance shall include, but not be limited to, hydrocarbons, petroleum,
gasoline, crude oil or any products or by-products thereof.  Lessee shall not
engage in any activity in or about the Premises which constitutes a Reportable
Use (as hereinafter defined) of Hazardous Substances without the express prior
written consent of Lessor and compliance in a timely manner (at Lessee's sole
cost and expense) with all Applicable Requirements (as defined in Paragraph
6.3).  "Reportable Use" shall mean (i) the installation or use of any above or
below ground storage tank, (ii) the generation, possession, storage, use,
transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with, any governmental authority, and (iii) the
presence in, on or about the Premises of a Hazardous Substance with respect to
which any Applicable Laws require that a notice be given to persons entering or
occupying the Premises or neighboring properties.  Notwithstanding the
foregoing, Lessee may, without Lessor's prior consent, but 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.  Lessor hereby approves of
Lessee's use of the substances listed on the Hazardous Materials List attached
hereto as Exhibit B.

     (b) Duty to Inform Lessor.  If Lessee knows (or has reasonable cause to
         ---------------------
believe as a result of its business operations in the Premises) 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 release or spill any Hazardous
Substance in, on, under or about the Premises (including, without limitation,
through the plumbing or sanitary sewer system) in violation of Applicable
Requirements.

     (c) Indemnification.  Lessee shall indemnify, protect, defend and hold
         ---------------
Lessor, its agents, employees, lenders and ground lessor, if any, 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 released or emitted in
violation of Applicable Requirements by 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

                                                                   Page 3 of 12

person, property or the environment created by Lessee, and the cost of
investigation (including consultants' and attorneys' fees and testing),
removal, remediation, restoration and/or abatement thereof, or of any
contamination therein involved, and shall survive the expiration or earlier
termination of this Lease.  No termination, cancellation or release agreement
entered into by Lessor and Lessee shall release Lessee from its obligations
under this Lease with respect to Hazardous Substances, unless specifically so
agreed by Lessor in writing at the time of such agreement.

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

     6.4  Inspection; Compliance with Law.  Lessor, Lessor's agents, employees,
          -------------------------------
contractors and designated representatives, and the holders of any mortgages,
deeds of trust or ground leases on the Premises ("Lenders") shall have the
right to enter the Premises at any time in the case of an emergency, and
otherwise at reasonable times upon one (1) business day's notice to Lessee, for
the purpose of inspecting the condition of the Premises and for verifying
compliance by Lessee with this Lease and all Applicable Requirements (as
defined in Paragraph 6.3), and Lessor shall be entitled to employ experts
and/or consultants in connection therewith to advise Lessor with respect to
Lessee's activities, including but not limited to Lessee's installation,
operation, use, monitoring, maintenance, or removal of any Hazardous Substance
on or from the Premises.  The costs and expenses of any such inspections shall
be paid by the party requesting same, unless a Default or Breach of this Lease
by Lessee or a violation of Applicable Requirements or a contamination, caused
or materially contributed to by Lessee, is found to exist or to be imminent, or
unless the inspection is requested or ordered by a governmental authority as
the result of any such existing or imminent violation or contamination.  In
such case, Lessee shall upon request reimburse Lessor or Lessor's Lender, as
the case may be, for the reasonable costs and expenses of such inspections.

7. Maintenance, Repairs, Utility Installations, Trade Fixtures and Alterations.
   ---------------------------------------------------------------------------

     7.1  Lessee's Obligations.
          --------------------

          (a) Subject to the provisions of Paragraphs 2.2 (Condition), 2.3
(Compliance with Covenants, Restrictions and Building Code), 7.2 (Lessor's
Obligations), 9 (Damage or Destruction), and 14 (Condemnation), Lessee shall,
at Lessee's sole cost and expense and at all times, keep the Premises and every
part thereof in good order, condition and repair (whether or not such portion
of the Premises requiring repair, or the means of repairing the same, are
reasonably or readily accessible to Lessee, and whether or not the need for
such repairs occurs as a result of Lessee's use, any prior use, the elements or
the age of such portion of the Premises), including, without limiting the
generality of the foregoing, all equipment or facilities specifically serving
the Premises, such as plumbing, heating, air conditioning, ventilating,
electrical, lighting facilities, boilers, fired or unfired pressure vessels,
fire hose connections if within the Premises, fixtures, interior walls,
interior surfaces of exterior walls, ceilings, floors, windows, doors, plate
glass, 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,
in the event Lessee fails to retain such contractor itself to procure and
maintain the contract for the heating, air conditioning and ventilating
systems, and it Lessor so elects, Lessee shall reimburse Lessor, upon demand,
for the reasonable cost thereof.

     (c) If Lessee breaches Lessee's obligations under this Paragraph 7.1,
Lessor may enter upon the Premises after thirty (30) days' prior written notice
to Lessee (except in the case of an emergency, in which case no notice shall be
required), perform such obligations on Lessee's behalf, and put the Premises In
good order, condition and repair, in accordance with Paragraph 13.2 below.

     7.2  Lessor's Obligations.  Subject to the provisions of Paragraphs 2.2
          --------------------
(Condition), 2.3 (Compliance with Covenants, Restrictions and Building Code),
4.2 (Common Area Operating Expenses), 6 (Use), 7.1 (Lessee's Obligations), 9
(Damage or Destruction) and 14 (Condemnation), Lessor, subject to reimbursement
pursuant to Paragraph 4.2, shall keep in good order, condition and repair with
respect to the Premises the foundations, exterior walls, structural condition
of interior bearing walls, roof, exterior roof membrane, fire sprinkler and/or
standpipe and hose (if located in the Common Areas) or other automatic fire
extinguishing system including fire alarm and/or smoke 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 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 wiring/cabling,
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 and Alterations to the interior of the
Premises 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 load bearing walls, or changing
or interfering with the fire sprinkler or fire detection systems and the cost
thereof, does not exceed $10,000 per project.

          (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 $10,000 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 five (5) 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 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.

     7.4  Ownership, Removal, Surrender, and Restoration.
          ----------------------------------------------

                                                                   Page 4 of 12
<PAGE>

          (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 anytime 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, casualty and condemnation excepted.  Ordinary
wear and tear shall not include any damage or deterioration that would have
been prevented by standard 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.  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.
The policy 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 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 lnsurance - 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 Building for the full replacement cost thereof, including the Tenant
Improvements.  Such insurance shall be for full replacement cost, as the same
shall exist from time to time.  Lessee-Owned Alterations and Utility
Installations, Trade Fixtures and Lessee's personal property shall be insured
by Lessee pursuant to Paragraph 8.4.  Lessor's policy or policies shall insure
against all risks of direct physical loss or damage (except 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
ordinance or law regulating the reconstruction or replacement of any undamaged
sections of the Building required to be demolished or removed by reason of the
enforcement of any building, zoning, safety or land use laws as the result of a
covered loss, but not including plate glass insurance.  Said policy or policies
shall also contain an agreed valuation provision in lieu of any co-insurance
clause, waiver of subrogation, and inflation guard protection causing an
increase in the annual property insurance coverage amount by a factor of not
less than the adjusted U.S. Department of Labor Consumer Price Index for All
Urban Consumers for the city nearest to where the Premises are located.

          (b) Rental Value.  Lessor shall also obtain and keep in force during
              ------------
the term of this Lease a policy or policies in the name of Lessor, with loss
payable to Lessor and any Lender(s), insuring the loss of the full rental and
other charges payable by all lessees of the Building to Lessor for one year
(including all Real Property Taxes, insurance costs, all Common Area Operating
Expenses and any scheduled rental increases).  Said insurance may provide that
in the event the Lease is terminated by reason of an insured loss, the period
of indemnity for such coverage shall be extended beyond the date of the
completion of repairs or replacement of the Premises, to provide for one full
year's loss of rental revenues from the dale of any such loss.  Said insurance
shall contain an agreed valuation provision in lieu of any coinsurance 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 not to exceed $10,000 per
occurrence in the event of such loss.

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

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

     8.4  Lessee's Property Insurance.  Subject to the requirements of
          ---------------------------
Paragraph 8.5, Lessee at its cost shall either by separate policy or, at
Lessor's option, by endorsement to a policy already carried, maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures and Lessee-Owned
Alterations and Utility Installations in, on, or about the Premises similar in
coverage to that carried by Lessor as the Insuring Party under Paragraph
8.3(a).  Such insurance shall be full replacement cost coverage with a
deductible not to exceed $50,000 per occurrence.  The proceeds from any such
insurance may 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.

     7.5  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, 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, copies of, or
certificates evidencing the existence and amounts of, the insurance required
under Paragraph 8.2(a) and 8.4.  No such policy shall be cancelable or subject
to reduction except after thirty-(30) days' prior written notice to Lessor.
Lessee shall at least thirty (30) days prior to the expiration of such
policies, furnish Lessor with evidence of renewals or 'insurance binders'
evidencing renewal thereof, or Lessor may order such insurance and charge the
cost thereof to Lessee, which amount shall be payable by Lessee to Lessor upon
demand.

     8.6  Waiver of Subrogation. Notwithstanding anything to the contrary in
          ---------------------
this Lease, 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 or
which would normally be covered under so called "all-risk" insurance.  The
effect of such releases and waivers of the right to recover damages shall not
be limited by the amount of insurance carried or required, or by any
deductibles applicable thereto.  Lessor and Lessee agree to have their
respective insurance companies issuing property damage insurance waive any
right to subrogation that such companies may have against Lessor or Lessee, as
the case may be, so long as the insurance is not invalidated thereby.

     8.7  Indemnity.  Except for Lessor's negligence and/or breach of express
          ---------
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, from and against any and all claims, loss of
rents and/or damages, costs, liens, judgments, penalties, loss of permits,

                                                                   Page 5 of 12

<PAGE>

attorneys' and consultants' fees, expenses and/or liabilities arising out of,
involving, or in connection with, any negligent or intentional act, omission or
neglect of Lessee, its agents, contractors, employees or invitees, and out of
any Default or Breach by Lessee in the performance in a timely manner of any
obligation on Lessee's part to be performed under this Lease.  The foregoing
shall include, but not be limited to, the defense or pursuit of any claim or
any action or proceeding involved therein, and whether or not (in the case of
claims made against Lessor) litigated and/or reduced to judgment.  In case any
action or proceeding be brought against Lessor by reason of any of the
foregoing matters, Lessee upon notice from Lessor shall defend the same at
Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor shall
cooperate with Lessee in such defense.  Lessor need not have first paid any
such claim in order to be so indemnified.

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

9.  Damage or Destruction.
    ---------------------

     9.1  Definitions.
          -----------

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

     (b) "Premises Total Destruction" shall mean damage or destruction to the
          --------------------------
Premises, other than Lessee-Owned Alterations and Utility Installations, the
repair cost of which damage or destruction is fifty percent (50%) or more of
the then Replacement Cost of the Premises (excluding Lessee-Owned Alterations
and Utility Installations and Trade Fixtures) immediately prior to such damage
or destruction.

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

     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 or Lessee
may terminate this Lease effective sixty (60) days following the date of
occurrence of such damage by giving written notice to the other of such party'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) as would otherwise be
required under Sections 9.2 and 9.3 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 affect.  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 Premises Partial Damage 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.  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 under this Lease against Lessor for any damage suffered by
reason of any such damage, destruction, repair, remediation or restoration.

                                                                   Page 6 of 12
<PAGE>

          (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 sixty (60) 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  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.

     9.8  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 its share of 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 commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal
income, gift, transfer 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.  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 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.
9.3 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,
Lessee's pro rata 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
thirty (30) 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.
In the event any such utilities or services are not separately metered to the
Premises or separately billed to the Premises, Lessee shall pay to Lessor a
reasonable proportion to be determined by Lessor of all such charges jointly
metered or billed with other premises in the Building, in the manner and within
the time periods set forth in Paragraph 4.2(d).

12.  Assignment and Subletting.
     -------------------------

     12.1 Lessor's Consent Required.
          -------------------------

          (a) Lessee shall not voluntarily assign, transfer, mortgage or
otherwise transfer or encumber (collectively, 'assign') or sublet all or any
part of Lessee's interest in this Lease or in the Premises without Lessor's
prior written consent given under and subject to the terms of Paragraph 35.

          (b) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option, be
void.

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

     12.2 Terms and Conditions Applicable to Assignment and Subletting.
          ------------------------------------------------------------

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

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

          (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the assignee or
subleases.

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

          (e) Each request for consent to an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the
proposed assignee or subleases, including but not limited to the intended use
and/or required modification of the Premises, if any, together with a non-
refundable deposit of $1,000, as reasonable consideration for Lessor's
considering and processing the request for consent.  Lessee agrees to provide
Lessor with such other or additional information and/or documentation as may be
reasonably requested by Lessor.

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

                                                                   Page 7 of 12
<PAGE>

     11.3 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) Lessor shall not, by reason of any other assignment of such sublease to
Lessor, nor by reason of the collection of the rents from a sublessee, be
deemed liable to the sublessee for any failure of Lessee to perform and comply
with any of Lessee's obligations to such sublessee under such Sublease.  Lessee
hereby irrevocably authorizes and directs any such sublessee, upon receipt of a
written notice from Lessor stating that a Breach exists in the performance of
Lessee's obligations under this Lease, to pay to Lessor the rents and other
charges due and to become due under the sublease.  Sublessee shall rely upon
any such statement and request from Lessor and shall pay such rents and other
charges to Lessor without any obligation or right to inquire as to whether such
Breach exists and notwithstanding any notice from or claim from Lessee to the
contrary.  Lessee shall have no right or claim against such sublessee, or,
until the Breach has been cured, against Lessor, for any such rents and other
charges so paid by said sublessee to Lessor.  (b) In the event of a Breach by
Lessee in the performance of its obligations under this Lease, Lessor, at its
option and without any obligation to do so, may require any sublessee to attorn
to Lessor, in which event Lessor shall undertake the obligations of the
sublessor under such sublease from the time of the exercise of said option to
the expiration of such sublease; provided, however, Lessor shall not be liable
for any prepaid rents or security deposit paid by such sublessee to such
sublessor or for any other prior defaults or breaches of such sublessor under
such sublease.  (c) (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.

13.  Default; Breach; Remedies.
     -------------------------

     13.1 Default; Breach.  A "Default" by Lessee is defined as a failure by
          ---------------
Lessee to observe, comply with or perform any of the terms, covenants,
conditions or rules applicable to Lessee under this Lease.  A "Breach" by
Lessee is defined as the occurrence of any one or more of the following
Defaults, and, where a grace period for cure after notice is specified herein,
the failure by Lessee to cure such Default prior to the expiration of the
applicable grace period, and shall entitle Lessor to pursue the remedies set
forth in Paragraphs 13.2 and/or 13.3:

          (a) The 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
thereunder 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 five (5) days following written notice thereof by or on behalf of
Lessor to Lessee.

          (c) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 39 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.

          (d) 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 1 01 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(a) 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.

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

     13.2 Remedies.  If Lessee fails to perform any affirmative duty or
          --------
obligation of Lessee under this Lease, within the time periods set forth above
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 reasonable 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 for the following six (6) months
to be made only by cashier's check.  In the event of a Breach of this Lease by
Lessee (as defined in Paragraph 13.1), with or without further notice or
demand, and without limiting Lessor in the exercise of any right or remedy
which Lessor may have by reason of such Breach, Lessor may:

          (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor.  In
such event Lessor shall be entitled to recover from Lessee: (i) the worth at
the time of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor
for all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable 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
suit for such rent and/or damages.

          (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 are located.

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

     13.3 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,

                                                                   Page 8 of 12

<PAGE>

processing and accounting charges, and late charges which may be imposed upon
Lessor by the terms of any ground lease, mortgage or dead 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 five percent (5%) 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.

     13.4 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 13.4, a reasonable
time shall in no event be more 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.  It more than ten percent (10%) of the
floor area of the Premises, or more than twenty-five percent (25%) of the
portion of the Common Areas designated for Lessee's parking, is taken by
condemnation, Lessee may, at Lessee's option, to be exercised in writing within
ten (10) days after Lessor shall have given Lessee written notice of such
taking (or in the absence of such notice, within ten (10) days after the
condemning authority shall have taken possession) terminate this Lease as of
the date the condemning authority takes such possession.  It 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 Rent shall be reduced by the extent to which Lessee's use of the
Premises is diminished.  No reduction of Base Rent shall occur if the
condemnation does not apply to any portion of the Premises or the parking.  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) less payment to Lessee for Lessee's relocation
expenses and/or loss of Lessee's Trade Fixtures, the unamortized value of any
tenant improvements paid for by Tenant and the "bonus value" of this Lease
(i.e. the difference between the Rent payable hereunder and the then fair
market rental value of the Premises) for the remainder of the Term.  In the
event that this Lease is not terminated by reason of such condemnation, Lessor
shall to the extent of its net severance damages received, over and above
Lessee's Share of the legal and other expenses incurred by Lessor in the
condemnation matter, repair any damage to the Premises caused by such
condemnation authority.

15.  Brokers' Fees.
     -------------

     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 agreed
          ----------------
in writing, Lessor agrees that: (a) if Lessee exercises any Option (as defined
in Paragraph 37.1) 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
(a) 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 shall deliver to
any potential lender or purchaser designated by Lessor such financial
statements of Lessee 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 and the written
assumption by such transferee of Lessor's obligations hereunder, 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 two percent (2%) per annum, but not
exceeding the maximum rate allowed by law, in addition to the potential late
charge provided for in Paragraph 13.3.

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.

23.  Notices.
     -------

     22.1 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, 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

                                                                   Page 9 of 12

<PAGE>

that Party's address for delivery or mailing 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 thereon.  If
sent by regular mail, the notice shall be deemed given three (3) business days
after the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantees next day delivery shall be deemed given twenty-four (24) hours after
delivery of the same to the United States Postal Service or courier.  If notice
is received on a Saturday or a Sunday or a legal holiday, it shall be deemed
received on the next business day.

24.  Waivers.  No waiver by either party of the Default or Breach of any term,
     -------
covenant or condition hereof by the other, shall be deemed a waiver of any
other term, covenant or condition hereof, or of any subsequent Default or
Breach by the other of the same or any other term, covenant or condition
hereof.  Either party's consent to, or approval of, any such act shall not be
deemed to render unnecessary the obtaining of such party's consent to, or
approval of, any subsequent or similar act by the other, 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.

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

26.  No Right To Holdover.  Lessee has no right to retain possession of the
     --------------------
Premises or any part thereof beyond the expiration or earlier termination of
this Lease.  In the event that Lessee holds over in violation of this Paragraph
26 then the Base Rent payable from and after the time of the expiration or
earlier termination of this Lease shall be increased to one hundred twenty-five
percent (125%) of the Base Rent applicable during the month immediately
preceding such expiration or earlier termination.  Nothing contained herein
shall be construed as a consent by Lessor to any holding over by Lessee.

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

28.  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.

29.  Subordination; Attornment; Non-Disturbance.

     29.1 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.  It 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.

     29.2 Attornment.  Subject to the non-disturbance provisions of Paragraph
          ----------
29.3, 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 except for ongoing defaults (such as a
continuing failure to repair and maintain the Premises), (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-

     29.3 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.

     28.4 Self-Executing.  The agreements contained in this Paragraph 29 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, in a commercially reasonable form, as may be reasonably
required to separately document any such subordination or non-subordination,
attainment and/or non-disturbance agreement as is provided for herein.

30.  Attorneys' Fees.  If any Party or Broker brings an action or proceeding to
     ---------------
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonable attorneys' fees.  Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment.  The term "Prevailing Party" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense.  The
attorneys' fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees
reasonably incurred.  Lessor shall be entitled to attorneys'' fees, costs and
expenses incurred in preparation and service of notices of Default and
consultations in connection therewith, whether or not a legal action is
subsequently commenced in connection with such Default or resulting Breach.
Broker(s) shall be intended third party beneficiaries of this Paragraph 30.

31.  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 upon (1) business day's notice to
Lessee for the purpose of showing the same to prospective purchasers, lenders,
or, in the last six (6) months of the Term, 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.

32.  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.

33.  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
reasonably 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).

34.  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.

                                                                  Page 10 of 12

35.  Consents.
     --------

     (a) Except for Paragraph 32 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 attorneys' 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
shall be paid by Lessee to Lessor upon receipt of an invoice and supporting
documentation therefor.  Lessor's consent to any act, assignment of this Lease
or subletting of the Premises by Lessee shall not constitute an acknowledgment
that no Default or Breach by Lessee of this Lease exists, nor shall such
consent be deemed a waiver of any then existing Default or Breach, except as
may be otherwise specifically stated in writing by Lessor at the time of such
consent.

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

36.  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.

prior Options to extend or renew this Lease have been validly exercised.

38.  Effect of Default on Options.
     ----------------------------

     (a) Lessee shall have no right to exercise an Option, notwithstanding any
provision in the grant of Option to the contrary: (i) during the period
commencing with the giving of any notice of Default under Paragraph 13.1 and
continuing until the noticed Default is cured, or (ii) during the period of
time any monetary obligation due Lessor from Lessee is unpaid (without regard
to whether notice thereof is given Lessee), or (iii) during the time Lessee is
in Breach of this Lease, or (iv) in the event that Lessor has given to Lessee
three (3) or more notices of separate monetary Defaults under Paragraph 13.1
during the twelve (I 2) month period immediately preceding the exercise of the
Option, whether or not the Defaults are cured.

on the part of said Party to institute suit for recovery of such sum.  If it

to pay such sum or any part thereof, said Party shall be entitled to recover
such sum or so much thereof as it was not legally required to pay under the
provisions of this Lease.

43.  Authority.  If either Party hereto is a corporation, trust, or general or

required by an institutional insurance company or pension plan Lender in

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

          L. Lessee's Contribution:  The term "Lessee's Contribution" is
             ---------------------
 defined in paragraph 5A.

     2. BUILDING PLANS:
        --------------

          A. Building Shell Plans:  Lessor has provided Lessee with a complete
             --------------------
 set of the Building Shell Plans.

          B. Preliminary Plans For Interior Improvements:  Lessor hereby
             -------------------------------------------
approves of Lessee's space plan dated November 15, 2000, prepared by Stafford
Space Planning.  On or before December 13, 2000 Lessee shall cause to be
prepared and delivered to Lessor fully engineered construction drawings for the
construction of the Interior Improvements for Lessor's approval, which approval
shall not be unreasonably withheld.  If Lessor fails to approve or disapprove
the proposed final plans within five (5) days following delivery of the final
plans to Lessor, the final plans proposed by Lessee shall be deemed to be the
approved Final Interior Improvement Plans for the purposes of this Agreement.
If Lessor disapproves the proposed final plans in any respect, it shall deliver
to Lessee its written proposal for required changes and the parties shall
negotiate in good faith to reach agreement on the final plans.

          C. Application For Approvals:  Lessor shall use its best efforts to
             -------------------------
obtain all governmental approvals and permits necessary for construction of the
Building in accordance with Building Plans.
          D. Termination:  If the parties are unable to agree upon the Final
             -----------
Interior Improvement Plans on or before January 15, 2001, or if all permits
required for construction of the Building have not been issued on or before
March 1, 2001, then Lessee, in its sole discretion, may terminate this
Agreement and the Lease by giving Lessor written notice.

          E. Changes to Building Plans after Final Approval:  Neither party
             ----------------------------------------------
shall have the right to require extra work or make any modifications with
respect to the construction of the Building, without the prior written consent
of the other party as to any change, provided, however, that Lessor shall have
the right to make changes to the Building Shell Plans, so long as the cost of

                                     - 3 -

<PAGE>

implementing each such change shall not exceed $2500 individually and so long
as the aggregate cost of all such changes made to the Building Shell Plans
shall not exceed $10,000. Lessor shall promptly provide Lessee with copies of
any such changes made to the Building Shell Plans.  Notwithstanding the
foregoing, Lessor shall have no right to make any changes to the Building Shell
Plans that could have a material adverse effect on the Building, including,
without limitation, the structural integrity of the Building, the fire and life
safety systems and all other operating systems and utility installations in the
Building without first obtaining Lessee's written consent.  The parties shall
confer and negotiate in good faith to reach agreement on such requested
changes.

     3. CONSTRUCTION CONTRACT:
        ---------------------

          A. Selection of General Contractor:  Lessor shall cause at least
             -------------------------------

three (3) general contractors to bid for construction of the Interior
Improvements.  All bids shall be opened simultaneously.  Lessor may select the
"General Contractor" to construct the Building; provided that Lessee approves
Lessor's selection, which approval shall not be unreasonably withheld.
Notwithstanding Lessee's right to approve the General Contractor, the General
Contractor shall be the contractor only of Lessor, and Lessee shall have no
liability to the General Contractor under any construction contract or
otherwise with respect to the Building.

     4. COMMENCEMENT AND COMPLETION OF BUILDING:
        ---------------------------------------

          A. Lessor's Obligation to Construct the Building:  As soon as the
             ---------------------------------------------
Building Plans have been approved, all necessary governmental approvals and
permits have been obtained, and the bids have been accepted, Lessor shall cause
construction of the Building Shell and the Interior Improvements to be
commenced and diligently prosecuted to completion, so that the Building will be
Substantially Complete by April 1, 2001.
          B. Delivery of Possession:  When the Building is Substantially
             ----------------------
Complete, Lessor shall deliver possession of the Building to Lessee.  However,
Lessee shall have no obligation to accept possession of the Building or
commence payment of rent until the later of (i) the date the Building is
Substantially Complete, or (ii) April 1, 2001, provided, however, that Lessor
is providing Lessee with one (1) month's free rent pursuant to the terms of the
Lease.

     5. PAYMENT OF CONSTRUCTION COSTS:
        -----------------------------

          A. Lessee's Contribution to Interior Improvement Costs:

                (1) Lessor shall pay and be solely responsible for all costs to
design, construct and develop the Building Shell.  Lessee's only obligation to
pay any cost of constructing the Building shall be limited to the positive
difference, if any, between the total Interior Improvement Costs and the
Interior Improvement Allowance, such difference being referred to herein as the
"Lessee's Contribution."  The parties acknowledge that Lessee shall have no
obligation to pay any cost of constructing any portion of the Building in
excess of the Lessee's Contribution.  Lessee shall pay the Lessee's
Contribution as follows: (a) Lessor shall cause the Lessor's Architect and the
General Contractor both to certify to Lessee when construction of the Interior
Improvements is

                                     - 4 -

<PAGE>

twenty-five percent (25%) complete, fifty percent (50%) complete, and seventy-
five (75%) complete.  Lessee shall pay Lessor within fifteen (15) days after
Lessee has received such certifications from both the Lessor's Architect and
the General Contractor in each instance, twenty-five percent (25%) of the
aggregate Lessee's Contribution, which shall be calculated based upon the
Interior Improvement Costs.  Within thirty (30) days after the Interior
Improvements are Substantially Complete and the amount of all Interior
Improvement Costs have been finally determined as provided below, Lessee shall
pay Lessor any portion of the Lessee's Contribution that remains due and
unpaid.  Failure of Lessee to make timely payments to Lessor as provided herein
and under applicable notice and cure provisions of the Lease shall constitute a
default under the Lease, and in such event, Lessor shall be entitled to enforce
all of its rights and remedies under the Lease.

                (2) As soon as possible after commencement of the Lease, Lessee
shall designate as Lessee's property Interior Improvements having a cost
approximately equal to the Lessee's Contribution.  Property designated as
Lessee's property under the terms of this paragraph shall constitute Lessee's
property for purposes of the Lease, and Lessee shall be entitled to all
investment tax credit, depreciation, and other tax attributes relating to such
property.  At the expiration or sooner termination of the Lease, all Interior
Improvements not designated as Lessee's property under this paragraph shall be
surrendered to Lessor in accordance with the terms of the Lease.

                 (3) When the Interior Improvements are Substantially
Completed, Lessor shall submit to Lessee a final and detailed accounting of all
Building Shell and Interior Improvement Costs paid by Lessor, certified to be
true and correct by Lessor's financial officers.  Lessee may audit the books,
records, and supporting documents of Lessor to the extent necessary to
determine the accuracy of such accounting during normal business hours after
giving Lessor at least forty-eight (48) hours written notice.  Lessee shall
bear the cost of such audit, unless such audit discloses that Lessor has
overstated the total costs by more than two percent (2%) of the actual amount
of such costs, in which event Lessor shall pay the costs of Lessee's audit.
Lessor shall promptly refund any overpayments to Lessee.

          B. Financing of Building:  If Lessor has not closed a commitment for
             ---------------------
financing sufficient to complete construction of the Building as provided in
this Agreement and delivered a copy of such financing documents to Lessee by
February 15, 2001, or, if such commitment has not closed such that Lessor can
provide Lessee with such documents, Lessor has, in lieu of such documents,
provided Lessee, by February 15, 2001, with financial documentation, in a form
acceptable to Lessee, which evidences the ability of Lessor to finance the
Building Shell and Interior Improvement work, then in such event Lessee may
terminate this Agreement and the Lease by giving Lessor written notice.

     6. LESSEE'S RIGHT TO ENTER:  Lessee, and its authorized representatives,
        -----------------------
shall have the right to enter the Building at all reasonable times for the
purpose of inspecting the progress of construction of the Building Shell and
the Interior Improvements.  The General Contractor shall give Lessee at least
sixty (60) days prior written notice of its estimated date for Substantial
Completion of

                                     - 5 -

<PAGE>

the Building, so that Lessee may cause its fixtures and equipment to be
ordered.  When construction of the Building has proceeded to the point where
Lessee's work of installing its fixtures and equipment in the Building can be
commenced in accordance with good construction practice, the General Contractor
also shall notify Lessee to that effect.

     7. CONSTRUCTION WARRANTY FOR THE BUILDING:  Notwithstanding anything to
        --------------------------------------
the contrary in the Lease, effective upon delivery of the Building to Lessee,
Lessor does hereby warrant (i) that the Building Shell and the Interior
Improvements were constructed in accordance with all Applicable Laws, as
defined in the Lease, including all applicable covenants, conditions or
restrictions and the rules, regulations, codes, statutes, ordinances, and laws
of all governmental and quasi-governmental authorities having jurisdiction over
the Building, (ii) that the Building Shell and Interior Improvements were
constructed in accordance with the Building Plans and in a good and workmanlike
manner; (iii) that all material and equipment installed in the Building
conformed to the Building Plans, was new and otherwise of good quality and was
installed in accordance with all vendor's and manufacturer's specifications,
instructions and requirements; and (iv) that all material and equipment
installed in the Building has been paid for and is free of liens, security
interests or chattel mortgages.  All construction, product and equipment
warranties and guarantees obtained by Lessor shall, to the extent obtainable,
provide that such warranties and guarantees shall also run to the benefit of
Lessee and its successors and assigns.  Lessee shall have the benefit of any
construction, product and equipment warranties and guarantees in favor of
Lessor that would assist Lessee in correcting defects and in discharging any of
Lessee's obligations regarding the repair and maintenance of the Premises.
Upon written request by Lessee, Lessor shall inform Lessee of all written
construction, product and equipment warranties and guarantees in favor of
Lessor which affect the Building.  Lessor shall cooperate with Lessee in
enforcing such warranties and guarantees and in bringing any suit that may be
necessary to enforce liability (i) at Lessor's sole expense with regard to any
defect for which Lessor is responsible under this paragraph 7 or under the
Lease, and (ii) also with regard to any defect for which Lessor is not
responsible under this paragraph 7 or under this Lease so long as Lessee pays
all costs reasonably incurred by Lessor in doing so.  Notwithstanding anything
to the contrary contained in the Lease or this Agreement, Lessee's acceptance
of the Building shall not be deemed a waiver of the foregoing warranty, and
Lessor shall promptly repair all violations of the warranty set forth in this
paragraph at its sole cost and expense.

     8. DELIVERY OF POSSESSION, PUNCH LIST AND ACCEPTANCE AGREEMENT:  As soon
        -----------------------------------------------------------
as the Building is Substantially Completed and Lessor has given Lessee
reasonable prior written notice of the time and date therefor, Lessor and
Lessee shall together walk through the Premises and inspect all of the
Building.  After such inspection has been completed, each party shall sign an
acceptance agreement, which shall (i) include a list of all "punch list" items
which the parties agree are to be corrected by Lessor and (ii) shall state the
Commencement Date.  Lessor shall use reasonable efforts to complete and/or
repair such "punch list" items within thirty (30) days after executing the
acceptance agreement.  The parties' preparation of such a "punch list" and
execution of an acceptance agreement shall not, however, be deemed an
acceptance by Lessee of the Building as complete or free from defects and shall
not in any way affect Lessor's warranty obligations under this Agreement.

                                     - 6 -

<PAGE>

     9. DELIVERY OF DOCUMENTS:  Lessor shall deliver to Lessee (i) within
        ---------------------
thirty (30) days after the same is obtained by Lessor, any temporary or
permanent certificates of occupancy issued by the City of Folsom with respect
to any of the Building; (ii) within sixty (60) days after Substantial
Completion of the Building, a complete "as-built" set of Mylar reproducible
Building Plans reflecting all approved changes in the work; and (iii) within
thirty (30) days after Substantial Completion of the Building, complete
maintenance and operating manuals for all the equipment, fixtures and systems
that are part of the Building.

     10. RISK OF LOSS:  Risk of loss of the Building prior to the Commencement
         ------------
Date of the Lease shall be borne by Lessor.  At all times prior to the
Commencement Date of the Lease, Lessor at its sole cost and expense shall
maintain so-called contingent liability and broad form "builder's risk"
insurance with coverage in an amount equal to the replacement cost of the
Building Shell plus the Interior Improvement Costs.  The insurance policy (i)
shall be in a form reasonably satisfactory to Lessee, (ii) shall be carried
with a company reasonably acceptable to Lessee, (iii) shall provide that such
policy shall not be subject to cancellation or change except after at least ten
(10) days prior written notice to Lessee, and (iv) shall contain a "cross
liability" provision insuring Lessor and Lessee against any loss caused by the
negligence of the other party.  Lessee shall be designated as a named insured
on said insurance policy and the "deductible" thereunder shall not exceed Ten
Thousand Dollars ($10,000).  If the Building is damaged or destroyed prior to
the Commencement Date of the Lease, Lessee shall have the right to terminate
the Lease, if the Building, in the reasonable opinion of the Lessor's
Architect, cannot be Substantially Complete prior to May 1, 2001.  If the Lease
is so terminated, Lessee shall be entitled to that amount of the builder's risk
insurance proceeds equal to the amount, if any, paid by Lessee for construction
of the Interior Improvements prior to the termination date.  If the Building is
damaged or destroyed and the Lease is not terminated pursuant to the terms of
the Lease or this Agreement, Lessor shall promptly and diligently complete
construction of the Building in accordance with this Agreement and all
insurance proceeds with respect to the loss shall be paid to the contractors
completing the Building as the work progresses in accordance with customary
institutional lending practices.

     11. RIGHTS UPON TERMINATION:  If the Lease is terminated pursuant to any
         -----------------------
provision of this Agreement, then in addition to all other amounts due Lessee
hereunder, all security deposits, prepaid rent, and other monies paid by Lessee
under the terms of the Lease or this Agreement (including, without limitation,
the Lessee's Contribution) shall be returned to Lessee upon demand and,
thereupon, neither party shall have any further rights or obligations under the
terms of the Lease or this Agreement.

     12. MISCELLANEOUS:  Time is of the essence of this Agreement.  This
         -------------
Agreement is the result of negotiations among and has been reviewed by all
parties.  Accordingly, this Agreement shall be deemed to be the product of both
parties hereto, and no ambiguity shall be construed in favor of or against
either party.  This Agreement may not be modified or amended, nor may any
provision hereof be waived, except in a writing signed by the parties to this
Agreement.  This Agreement shall be binding upon and shall inure to the benefit
of the parties hereto and their respective heirs, personal representatives,
successors and assigns.  The captions used in this Agreement are for

period, Lessee shall have the right to terminate the Lease.

increase the obligations or decrease the rights of Lessee under the Lease.

     56.    Option to Renew. If it becomes necessary to determine the Market
            ----------------
Rate by appraisal, real estate appraiser(s), all of whom shall be Members of
the Appraisal Institute and who have at least five (5) years experience
appraising similar space located in the vicinity of the Premises shall be
appointed and shall act in accordance with the following procedures:

            (i) If the parties are unable to agree on the Market Rate within
the allowed time, either party may demand an appraisal by giving written notice
to the other party, which demand to be effective must state the name, address
and qualifications of an appraiser selected by the party demanding an appraisal
(the "Notifying Party"). Within ten (10) days following the Notifying Party's
appraisal demand, the other party (the "Non-Notifying Party") shall either
approve the appraiser selected by the Notifying Party or select a second
properly qualified appraiser by giving written notice of the name, address and
qualification of such appraiser to the Notifying Party.  If the Non-Notifying
Party fails to select an appraiser within the ten (10) day period, the
appraiser selected by the Notifying Party shall be deemed selected by both
parties and no other appraiser shall be selected.  If two appraisers are
selected, they shall select a third appropriately qualified appraiser.  If the
two appraisers fail to select a third qualified appraiser, the third appraiser
shall be appointed by the then presiding judge of the county where the Premises
are located upon application by either party.

            (ii) If only one appraiser is selected, that appraiser shall notify
the parties in simple letter form of its determination of the Market Rate
within fifteen (15) days following his selection, which appraisal shall be
conclusively determinative and binding on the parties as the appraised Market
Rate.  If multiple appraisers are selected, the appraisers shall meet not later
than ten (10) days following the selection of the last appraiser.  At such
meeting the appraisers shall attempt to determine the Market Rate as of the
commencement date of the extended term by the agreement of at least two (2) of
the appraisers.  If two (2) or more of the appraisers agree on the Market Rate
at the initial meeting, such agreement shall be determinative and binding upon
the parties hereto and the agreeing appraisers shall, in simple letter form
executed by the agreeing appraisers, forthwith notify both Landlord and Tenant
of the amount set by such agreement.  If multiple appraisers are selected and
two (2) appraisers are unable to agree on the Market Rate, all appraisers shall
submit to Landlord and Tenant an independent appraisal of the Market Rate in
simple letter form within twenty (20) days following appointment of the final
appraiser.  The parties shall then determine the Market Rate by averaging the
appraisals; provided that any high or low appraisal, differing from the middle
appraisal by more than ten percent (10%) of the middle appraisal, shall be
disregarded in calculating the average.

<PAGE>

            (iii) If only one appraiser is selected, then each party shall pay
one-half of the fees and expenses of that appraiser.  If three appraisers are
selected, each party shall bear the fees and expenses of the appraiser it
selects and one-half of the fees and expenses of the third appraiser.

     63.    Reasonable Expenditures. Any expenditure by a party permitted or
            -----------------------

required under the Lease, for which such party is entitled to demand and does
demand reimbursement from the other party, shall be limited to the fair market
value of the goods and services involved, shall be reasonably incurred and
shall be substantiated by documentary evidence available for inspection and
review by the other party or its representative during normal business hours.
