Premises as of the Commencement Date. Said warranties shall not apply to any
Alterations or Utility Installations (defined in Paragraph 7.3(a) made or to

Term of this Lease are as specified in Paragraph 1.3.

         3.2       EARLY POSSESSION. If an early Possession Date is specified

the Early Possession Date but prior to Commencement Date, the obligation to
pay Base Rent shall be abated for the period of such early occupancy. All of
the terms of this Lease, however, (including but not limited to the
obligations to pay Lessee's Share of Common Area Operating Expenses and to
carry the insurance required by Paragraph 8) shall be in effect during such
period. Any such early possession shall not affect nor advance the expiration
Date of the Original Term.

         3.3       DELAY IN POSSESSION. If for any reason Lessor cannot
deliver possession of the Premises to Lessee by the Early Possession Date, if
one is specified in Paragraph 1.4, or if no Early Possession Date is

liability therefor, nor shall such failure affect the validity of the Lease,
or the obligations of Lessee hereunder, or extend the term hereof, in such

pay rent or perform any other obligation of Lessee under terms of this Lease
until Lessor delivers possession of the Premises to Lessee. If possession of
the Premises is not delivered to Lessee within sixty (60) days after the
Commencement Date, Lessee may, at its option, by notice in writing to Lessor
within (10) days after the end of said sixty (60) day period, cancel this
Lease, in which event the parties shall be discharged from all obligations
hereunder, provided further, however that if such written notice of Lessee is
not received by Lessor within said ten (10) day period, Lessee's right to
cancel this Lease hereunder shall terminate and be of no further force or
effect. Except as may be otherwise provided, and regardless of when the
Original Term actually commences, if possession is not tendered to Lessee
when required by this Lease and Lessee does not terminate this Lease, as
aforesaid, the period free of the obligation to pay Base Rent, if any, that
Lessee would otherwise have enjoyed shall run from the date of delivery of
possession

Lease to provide the same or some of them.

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

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

5.       SECURITY DEPOSIT. Lessee shall deposit with Lessor upon Lessee's
execution hereof the Security Deposit set forth in Paragraph 1.2 as security
for Lessee's faithful performance of Lessee's obligations under this Lease.
If Lessee fails to pay Base Rent or other rent charges due hereunder, or
otherwise Defaults under this Lease (as defined in Paragraph 13.1), Lessor
may use, apply or retain all or any portion of said Security Deposit for the
payment of any amount due Lessor or to reimburse or compensate Lessor for any
liability, cost, expense, loss or damage (including attorneys' fees) which
Lessor may suffer or incur by reason thereof. If Lessor uses or applies all
or any portion of said Security Deposit, Lessee shall within ten (10) days
after written request therefore deposit monies with Lessor sufficient to
restore said Security Deposit to the full amount required by this Lease. Any
time the Base Rent increases during the term of this Lease, Lessee shall,
upon written request from Lessor, deposit additional monies with Lessor as an
addition to the Security Deposit so that the total amount of the Security
Deposit shall at all times bear the same proportion to the then current Base
Rent as the initial Security Deposit bear to the initial Base Rent set forth
in Paragraph 1.5. Lessor shall not be required to keep all or any part of the
Security Deposit separate from its general accounts. Lessor shall, at the
expiration or earlier termination of the term hereof and after Lessee has
vacated the Premises, return to Lessee (or, at Lessor's option, to the last
assignee, if any, of Lessee's interest herein), that portion of the Security
Deposit not used or applied by Lessor. Unless otherwise expressly agreed in
writing by Lessor, no part of the Security Deposit shall be consider to be
held in trust, to bear interest or other increment for its use, or to be
prepayment for any monies to be paid by Lessee under this Lease.

6.       USE.

         6.1      PERMITTED USE.

                  (A) Lessee shall use and occupy the Premises only for the

reasonably comparable thereto, and for no other purpose. Lessee shall not use or
permit the use of the Premises in a manner that is

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

         6.2       HAZARDOUS SUBSTANCES.

                   (a) REPORTABLE USES REQUIRE CONSENT. The term "Hazardous
Substance" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of

be on the Premises, is either: (i) potentially injurious to the public
health, safety or welfare, the environment, or the Premises; (ii) regulated
or monitored by any governmental authority; or (iii) a basis for potential
liability of loss to any governmental agency or third party under the
applicable statute or common law theory. Hazardous Substance shall include,
but not be limited to, hydrocarbons, petroleum, gasoline, crude oil or any

or about the Premises of a Hazardous Substance with respect to which any
Applicable Laws require that a notice be given to persons entering or
occupying the Premises or neighboring properties. Notwithstanding the
foregoing, Lessee may, without Lessor's prior consent, but upon notice to
Lessor and in compliance with all Applicable Requirements, use any ordinary
and customary materials reasonably required to be used by Lessee in the
normal course of the Permitted Use, so long as such use is not a Reportable
Use and does not expose the Premises or neighboring properties to any
meaningful risk of contamination or damage or expose Lessor to any liability
therefore. In addition, Lessor may (but without any obligation to do so)
condition its consent to any Reportable Use of any Hazardous Substance by
Lessee upon Lessee's giving Lessor such additional assurances Lessor, in its
reasonable discretion, deems necessary to protect itself, the public, the
Premises and the environment against damage, contamination or injury and/or
liability therefore, including but not limited to the installation (and, at
Lessor's option, removal on or before Lease contamination or injury and/or
liability therefore, including but not limited to the installation (and, at
Lessor's option, removal on or before Lease expiration or earlier
termination) of reasonably necessary protective modification to the Premises
(such as concrete encasements) and/or the deposit of an additional Security
Deposit under Paragraph 5 hereof.

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

                   (c) DUTY TO INFORM LESSEE. If Lessor knows, or has
reasonable cause to believe, that a Hazardous Substance has come to be
located in, on, under or about the Premises or the Building, Lessor shall
immediately give Lessee 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. Lessor shall not cause or permit any Hazardous
Substance to be spilled or released in, on, under or about the Premises
(including, without limitation, through the plumbing or sanitary sewer
system).

                   (d) INDEMNIFICATION. Lessee shall indemnify, protect,
defend and hold Lessor, its agents, employees, lenders and ground lessor, if
any, and the Premises, harmless from and against any and all damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, loss of
permits and attorneys' and consultants' fees arising out of involving any
Hazardous Substance brought onto the Premises by or for Lessee or by anyone
under Lessee's control. Lessee's obligations under this Paragraph 6.2(o)
shall include, but not be limited to, the effects of any contamination or
injury to person, property or the environment created or suffered by Lessee,
and the cost of investigation (including consultants' and attorneys' fees and
testing), removal, remediation, restoration and/or abatement thereof, or of
any contamination therein involved, and shall survive the expiration or
earlier termination of this lease. No termination, cancellation or release
agreement entered into by Lessor and Lessee shall release the 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, and the requirements of any
applicable fire insurance underwriter or rating bureau, and the
recommendations of Lessor's engineers and/or consultants, relating in any
manner to the Premises (including but not limited to matters pertaining to
(i) industrial hygiene, (ii) environmental conditions on, in, under or about
the Premises, including soil and groundwater conditions, and (iii) the use,
generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill, or release of any Hazardous Substance), now
in effect or which may hereafter come into effect. Lessee shall, within ten
(10) 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 of actual claim, notice,
citation, warning, complaint or report pertaining to or involving failure by
Lessee to the Premises to comply with any Applicable Requirements.

         Notwithstanding anything to the contrary contained herein, Lessee's
obligation to comply with Applicable Requirements, as set forth in Section
6.3 above, shall only apply if such compliance is required or necessitated by
Lessee's acts, use, or occupancy of the Premises. For example, if any
governmental authority should require the Building of the Premises to be
structurally strengthened against earthquake, or should require the removal
of asbestos from the Premises and such measures are imposed as a general
requirement applicable to all tenants rather than as a condition to Lessee's
specific use or occupancy of the PREMISES, such work shall be performed by
and at the sole cost of Lessor.

         It is being expressly agreed that Lessee shall have no obligation or
liability of any kind or nature with respect to contamination or Hazardous
Substances that existed at, on or under the Premises and Building (which
shall be deemed to include the underlying soil and groundwater) prior to the
commencement of this Lease or that was not caused by Lessee's acts, use or
occupancy of the Premises.

         To the best of Lessor's current, actual knowledge, none of Lessor's
tenants at the Office Building Project are in violation of subject to any
existing, pending or threatened investigation or order by any governmental
authority under any applicable federal, state or local law, regulation or
ordinance pertaining to air and water quality, the handling, transportation,
storage, treatment, usage or disposal of Hazardous Substances, air emissions,
other environmental matters and all zoning and land use matters.

                                       4

<PAGE>


         To the best of Lessor's current, actual knowledge, any handling,
transportation, storage, treatment or use of Hazardous Substances that has
occurred on the Premises to date is not in non-compliance with all Applicable
Requirements regulating same.

         To the best of Lessor's current, actual knowledge, no leak, spill,
release, discharge, emission or disposal of Hazardous Substances has occurred
on the Premises, Building and Industrial Center to date and the soil,
groundwater and soil vapor on or under the Premises, Building and Industrial
Center is free of Hazardous Substances as of the date the term of this Lease
commences.

         In the event of (i) a breach of the foregoing representations, or
(ii) the occurrence, release or threatened release of any Hazardous
Substances on or about the Premises, Building and Industrial Center during
the term hereof that is not caused by Lessee, Lessor, at Lessor's sole
expense, shall (a) promptly remove, eliminate or remediate said Hazardous
Substances and/or take such other action with respect thereto as is required
by any federal, state or local government agency having jurisdiction thereof.

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

ALTERATIONS.

         7.1      LESSEE'S OBLIGATIONS.

                  (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

reimburse Lessor, upon demand, for the cost thereof.

                  (c) If Lessee fails to perform Lessee's obligations under

exterior or interior surfaces of exterior walls nor shall Lessor be obligated
to maintain, repair or replace windows, doors or plate glass of the Premises.
Lessee expressly waives the benefit of any statute now or hereafter in effect
which would otherwise afford Lessee the right to make repairs at Lessor's
expense or to terminate this Lease because of Lessor's failure to keep the
Building, Industrial Center or Common Areas in good order, condition and
repair.

         7.3      UTILITY INSTALLATIONS, TRADE FIXTURES, ALTERATIONS.

                  (a) DEFINITIONS; CONSENT REQUIRED. The term "Utility

                  (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

specific consent, shall be deemed condition 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 Installations to Lessor prior to

adverse judgment that may be rendered thereon before the enforcement thereof
against the Lessor or the Premises. If Lessor shall require, Lessee shall

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 affect of such lien or claim. In addition, Lessor may require Lessee to
pay Lessor's attorney's fees and costs in participating in such action if
Lessor shall decide it is to its best interest to do so.

         7.4      OWNERSHIP, REMOVAL, SURRENDER, AND RESTORATION.

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

                  (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.

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

prevented by good maintenance practice or by Lessee performing all of its
obligations under this Lease. Except as otherwise agreed or specified herein,
the Premises, as surrendered, shall include the Alterations and Utility
Installations. The obligation of Lessee shall include the repair of any
damage occasioned by the installation, maintenance or removal of Lessee's
Trade Fixtures, furnishings, equipment, and Lessee-Owned Alterations and
Utility Installations, as well as the removal of any storage tank installed

8.       INSURANCE; INDEMNITY.

         8.1      PAYMENT OF PREMIUM INCREASES.

                  (a) As used herein, the term "Insurance Cost Increase" is
defined as any increase in the actual cost of the insurance applicable to the
Building and required to be carried by Lessor pursuant to Paragraphs 8.2(b),
8.3(a), and 8.3(b), ("Required Insurance"), over and above the Base Premium,
as hereinafter defined, calculated on an annual basis. "Insurance Cost
Increase" shall include, but not be limited to, requirements of the holder of
a mortgage or deed of trust covering Premises, increased valuation of the
Premises, and/or a general premium rate increase. The term "Insurance Cost
Increase" shall not, however, include any premium increase resulting from the
nature of the occupancy of any other lessee of the Building. If the parties
insert a dollar amount in Paragraph 1.9, such amount shall be considered the
"Base Premium". If a dollar amount has not been inserted in Paragraph 1.9 and
if the Building has been previously occupied during the twelve (12) month
period immediately preceding the Commencement Date, the "Base Premium" shall
be the annual premium applicable to such twelve (12) month period. If the
Building was not fully occupied during such twelve (12) month period, the
"Base Premium" shall be the lowest annual premium reasonably obtainable for
the Required Insurance as of the Commencement Date, assuming the most nominal
use possible of the Building. In no event, however, shall Lessee be
responsible for any portion of the premium cost attributable to liability
insurance coverage in excess of $1,000.0000 procured under paragraph 8.2(b).

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

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

                  (a) BUILDING AND IMPROVEMENTS. Lessor shall obtain and keep
in force during the term of this Lease a policy and policies in the name of
Lessor, with loss payable to Lessor and any Lender(s), insuring against loss
or damage to the Premises. Such insurance shall be for full replacement cost,
as the same shall exist from time to time, or the amount required by any
Lender(s), but in no event more than the commercially reasonable and
available insurable value thereof if, by reason of the unique nature or age
of this improvements involved, such latter amount is less than full
replacement cost. Lessee-Owned Alterations and Utility Installations, Trade
Fixtures and Lessee's personal property shall be insured by Lessee pursuant
to Paragraph 8.4. If the coverage is available and commercially appropriate,
Lessor's policy or policies shall insure against all risks of direct physical
loss or damage (except the perils of flood and/or earthquake unless required
by a Lender or included in the Base Premium), 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 by a Lender or included in the Base Premium), 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 leases 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 the rental revenues from the date of
any such loss. Said insurance shall contain an agreed valuation provision in
lieu of any co-insurance clause, and the amount of coverage shall be adjusted
annually to reflect the projected rental income, Real Property Taxes,
insurance premium costs and other expenses, if any otherwise payable, for the
next 12-month period. Common Area Operating Expenses shall include any
deductible amount in the event of such loss.

                   INDUSTRIAL/COMMERCIAL MULTI-TENANT LEASE--GROSS

<PAGE>


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

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

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

         8.5       INSURANCE POLICIES. Insurance required hereunder shall be
in companies duly licensed to transact business in the state where the
Premises are located and maintaining during the policy term a "General
Policyholders Rating" of at least B+, V, or such other rating as may be
required by a Lender, as set forth in the most current issue of "Best
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 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 modification except after 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, following notice to Lessee, order
such insurance and charge the cost thereof to Lessee, which amount shall be
payable by Lessee to Lessor upon demand.

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

         8.7       INDEMNITY. Except for Lessor's or its agents, contractors,
or employees negligence, or willful misconduct and/or breach of express
warranties, or its obligations hereunder, Lessee shall indemnify, protect,
defend and hold harmless the Premises, Lessor and its agents, Lessor's master
or ground lessor, partners and Lenders, from and against any and all claims,
loss of rents and/or damages, costs, liens, judgements, penalties, loss of
permits, attorneys' and consultants' fees, expenses and/or liabilities
arising out of, involving, or in connection with the occupancy of the
Premises by Lessee, the conduct of Lessee's business, any act, omission, or
neglect of Lessee, it's 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
judgement. In case any action or proceeding be brought against Lessor by
reason of any of the foregoing matters, Lessee upon notice from Lessor shall
defend the same at Lessee's expense by counsel reasonably satisfactory to
Lessor and Lessor shall cooperate with Lessee in such defense. Lessor need
not have first paid any such claim in order to be so indemnified.

         8.8       EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be
liable for injury or damage to the person or goods, wares, merchandise or
other property of Lessee. Lessee's employees, contractors, invitees,
customers, or any other person in or about the Premises, whether such damage
or injury is caused by or results from fire, steam, electricity, gas, water
or rain, or from the breakage, leakage, obstruction or other defects of
pipes, fire sprinklers, wires, appliances, plumbing, air conditioning or
lighting fixtures, or from any other cause, whether said injury or damage
results from conditions arising upon the Premises or upon other portions of
the Building of which the Premises are a part, from other sources or places,
and regardless of whatever 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
percent (50%) of the then Replacement Cost (as defined in Paragraph 9.1(d))
of the Premises (excluding Lessee-Owned Alterations and Utility Installations
and Trade Fixtures) immediately prior to such damage or destruction.

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

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

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

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

         9.2      PREMISES PARTIAL DAMAGE--INSURED LOSS. If Premises Partial
Damage that is an Insured Loss occurs, then Lessor shall, at Lessor's
expense, repair such damage (but not Lessor'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

                   INDUSTRIAL/COMMERCIAL MULTI-TENANT LEASE--GROSS
                                       7

<PAGE>


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 shall terminate sixty (60) days
following the occurrence of the damage or destruction. Unless otherwise
agreed, Lessee shall in no event have any right to reimbursement from Lessor
for any funds contributed by Lessee to repair any such damage or destruction.
Premises Partial Damage due to flood or earthquake shall be subject to
Paragraph 9.3 rather than Paragraph 9.2, notwithstanding that there may be
some insurance coverage, but the net proceeds of any such insurance shall be
made available for the repairs if made by either Party.

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

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

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

         9.6      ABATEMENT OF RENT; LESSEE'S REMEDIES.

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

                  (b) If Lessor shall be obligated to repair or restore the
Premises under the provision of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises
within ninety (90) days after such obligation shall accrue, Lessee may, at
any time prior to the commencement of such repair or restoration, give
written notice to Lessor and to any Lenders of which Lessee has actual notice
of Lessee's election to terminate this Lease on a date not less than sixty
(60) 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
commence the repair or restoration of the Premises within thirty (30) days
after the receipt of such notice, this Lease shall continue in full force and
effect. "Commence" as used in this Paragraph 9.6 shall mean either the
unconditional authorization of the preparation of the required plans, or the
beginning of the actual work on the Premises, whichever occurs first.

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

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

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

10.      REAL PROPERTY TAXES.

         10.1     PAYMENT OF TAXES. Lessor shall pay the Real Property
Taxes, as defined in Paragraph 10.2(a), applicable to the Industrial Center,
and except as otherwise provided in Paragraph 10.3, any increases in such
amounts over the Base Real Property Taxes 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 DEFINITIONS.

                  (a) As used herein, the term "Real Property Taxes" shall
include any form of real estate tax or assessment, general, special, ordinary
or extraordinary, and any license fee, commercial rental tax, improvement
bond or bonds, levy tax (other than inheritance, personal income or estate
taxes) imposed upon the Industrial Center by any authority having the direct
or indirect power to tax, including any city, state or federal government, or
any school, agricultural, sanitary, fire, street, drainage, or other
improvement district thereof, levied against any legal equitable interest of
Lessor in the Industrial Center or any portion thereof, Lessor's right to
rent or other income therefrom, and/or Lessor business of leasing the
Premises. The term "Real Property Taxes" shall also include any tax, fee,
levy, assessment or charge, or any increase therein, imposed by reason of
events occurring, or changes in Applicable Law taking effect, during the term
of this Lease, including the execution of this Lease, or any

                   INDUSTRIAL/COMMERCIAL MULTI-TENANT LEASE--GROSS
                                       8

<PAGE>


modification, amendment or transfer thereof, and any modification made to the
Premises by or for Lessee whether or not contemplated by the Parties, but not
including a change in ownership of the Industrial Center.

                  (b) As used herein, the term "BASE REAL PROPERTY TAXES"
shall be the amount of Real Property Taxes, which are assessed against the
Premises, Building or Common Area in the calendar year during which the Lease
is executed. 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 and tax year have
in common.

         10.3     ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses
shall not include Real Property Taxes specified in the tax assessor's records
and worksheets as being caused by additional improvements placed upon the
Industrial Center by other lessees or by Lessor for the exclusive enjoyment
of such other lessees. Notwithstanding Paragraph 10.1 hereof, Lessee shall,
however, pay to Lessor at the time Common Area Operating Expenses are
payable under Paragraph 4.2, the entirety of any increase in Real Property
Taxes if assessed solely by reason of Alteration, 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 valuation signed in the assessor's worksheets 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 the Lessor. If any of Lessee's
said property shall be assessed with Lessor's real property, Lessee shall pay
Lessor the taxes attributable to Lessee's property within ten (10) days after
receipt of a written statement setting forth the taxes applicable to Lessee's
property.

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

12.      ASSIGNMENT AND SUBLETTING.

         12.1     LESSOR'S CONSENT REQUIRED.

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

                  (b) a change in the control of Lessee shall constitute an
assignment requiring Lessor's consent. The transfer, on a cumulative basis,
of forty-nine percent (49%) or more of the voting control of Lessee shall
constitute a change in control for this purpose.

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

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

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

         12.2     TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND
SUBLETTING.

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

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

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

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

                  (e) Each request for consent to an assignment or subletting
shall be writing, accompanied by information relevant Lessor's determination as
to the financial and operational responsibility and appropriateness of the
proposed assignee or sublessee, including but not limited to the intended use
and/or required modification of the Premises, if any, together with a
non-refundable deposit of $1,000 or ten percent (10%) of the monthly Base Rent
applicable to the portion of the Premises which is the subject of the proposed
assignment or sublease whichever is greater, as

                   INDUSTRIAL/COMMERCIAL MULTI-TENANT LEASE--GROSS
                                       9

<PAGE>


reasonable consideration for Lessor's considering and processing the request
for consent. Lessee agrees to provide Lessor with such other or additional
information and/or documentation as may be reasonably requested by Lessor.

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

                  (g) The occurrence of a transaction described in paragraph
12.2(c) shall give Lessor the right (but not the obligation) to require that
the Security Deposit be increased by an amount equal to two (2) times the
then monthly Base Rent, and Lessor may make the actual receipt by Lessor of
the Security Deposit increase a condition to Lessor's consent to such
transaction.

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

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

                  (a) Lessee hereby assigns and transfers to Lessor fifty
percent (50%) above its cost of Lessee's interest in all rentals and income
arising from any sublease of all or a portion of the Premises heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and
apply same toward Lessee's obligations under this Lease; provided, however,
that until a Breach (as defined in Paragraph 13.1) shall occur in the
performance of Lessee's obligations under this Lease, Lessee may, except as
otherwise provided in this Lease, receive, collect, and enjoy the rents
accruing under such sublease. Lessor shall not, by reason of the foregoing
provision or any other assignment of such sublease to Lessor, nor by reason
of the collection of the rents from a 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 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 rights 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 sublessee to attorn to Lessor, in which
event Lessor shall undertake the obligations of the sublessor under such
sublease from the time of the exercise of said option to the expiration of
such sublease; provided, however, Lessor shall not be liable for any prepaid
rents or security deposit paid by such sublessee to such sublessor or for any
other prior defaults or breaches of such sublessor under such sublease.

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

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

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

13.      DEFAULT; BREACH; REMEDIES.

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

                  (a) The vacating of the Premises without the intention to
reoccupy the same, or the abandonment of the Premises.

                  (b) Except as expressly otherwise provided in this Lease,
the failure by Lessee to make any payments of Base Rent, Lessee's Share of
Common Area Operating Expenses, or any other monetary payment required to be
made by Lessee hereunder as and when due, the failure by Lessee to provide
Lessor with reasonable evidence of insurance or surety bond required under
this Lease, or the failure of Lessee to fulfill any obligation under this
Lease, where such failure continues for a period of five (5) days following
written notice thereof by or on behalf of Lessor to Lessee, except that which
endangers or threatens life or property where such failure continues for a
period of one (1) day.

                  (c) Except as expressly otherwise provided in this Lease,
the failure by Lessee to provide Lessor with reasonable written evidence (in
duly executed original form, if applicable) of (i) compliance with Applicable
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service
contracts required under Paragraph 7, (iii) the rescission of an unauthorized
assignment or subletting per Paragraph 12.1, (iv) a Tenancy Statement per
Paragraphs 16 or 37, (v) the subordination or non-subordination of this Lease
per Paragraph 30, (vi) the guaranty of the performance of Lessee's
obligations under this Lease if required under Paragraphs 1.11 and 37, (vii)
the execution of any document requested under Paragraph 42 (easements), or
(viii) any other documentation or information which Lessor may reasonably
require of Lessee under the terms of this Lease, where any such failure
continues for a period of fifteen (15) days following written notice by or on
behalf of Lessor to Lessee.

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

                  (e) The occurrence of any of the following events: (i) the
making by Lessee of any general arrangements or assignments for the benefit
of creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code
Section 101 or any successor statute thereto (unless, in the case of a
petition filed against Lessee, the same is dismissed within sixty (60) days;
(iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within
thirty (30) days; or (iv) the attachment, execution or other judicial seizure
of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within
thirty (30) days; provided, however, in the event that

                   INDUSTRIAL/COMMERCIAL MULTI-TENANT LEASE--GROSS
                                       10

<PAGE>


any provision of this Subparagraph 13.1(c) is contrary to any applicable law,
such provision shall be of no force or effect, and shall not affect the
validity of the remaining provisions.

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

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

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

                  (a) 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 the amount by which the unpaid rent which would have been earned
after termination until the time of award exceeds the amount of 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 (iii)
any other amount necessary to compensate Lessor for all the detriment
proximately award exceeds the amount of unpaid rent for the balance of the
terms after the time of award excess the amount of such rental by the Lessee
failure to perform its obligations under this Lease or which in the ordinary
course of things could 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 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
discount in 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 are recoverable therein, or Lessor may reserve the
right to recover all or any part thereof in a separate suit for such rent
and/or damages if a notice and grace may be given to Lessee under any
statute authorizing the forfeiture of leases for unlawful detainer shall also
constitute the applicable notice for grace period purposes required by
Subparagraph 13.1(b), (c) or (d). In such case, the applicable grace period
under this unlawful detainer statute shall run concurrently after the one
such statutory notice, and the failure of Lessee to cure the Default within
the greater of the two (2) such grace periods shall constitute both an
unlawful detainer and a Breach of this Lease entitle in Lessor to the remedies
provided for this Lease and/or by said statute.

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

                  (c) Pursue any other remedy now or hereafter available to
Lessor under the laws or judicial decisions of the state wherein the Premises
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 by reason of Lessee's occupancy
of the Premises.

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

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

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

                   INDUSTRIAL/COMMERCIAL MULTI-TENANT LEASE--GROSS
                                       11

<PAGE>


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

         15.1     PROCURING CAUSE. The Broker(s) named in Paragraph 1.14
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 39.1) granted under this Lease or any Option
subsequently granted, or (b) if Lessee acquires any rights to the Premises or
other premises in which Lessor has an interest, or (c) if Lessee remains in
possession of the Premises with the consent of Lessor after the expiration of
the term of this Lease after having failed to exercise an Option, or (d) if
said Brokers are the procuring cause of any other lease or sale entered into
between the Parties pertaining to the Premises and/or any adjacent property
in which Lessor has an interest, or (e) if Base Rent is increased, whether by
agreement or operation of an escalation clause herein, then as to any of said
transactions, Lessor shall pay said Broker(s) a fee in accordance with the
schedule of said Broker(s) in effect at the time of the execution of this
Lease.

         15.3     ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of
Lessor's interest in this Lease, whether such transfers 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 1.14 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 Paragraph 1.14 in
connection with the negotiation of this Lease and/or the consummation of the
transaction contemplated hereby, and that no broker or other 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
attorney' fees reasonably incurred with respect thereto.

16.      TENANCY AND FINANCIAL STATEMENTS.

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

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

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

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

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

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

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

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

23.      NOTICES.

         23.1     NOTICE REQUIREMENTS. All notices required or permitted by
this Lease shall be in writing and may be delivered in person (by hand or by
messenger or courier service or may be sent by regular, certified or
registered mail or U.S. Postal Service Express Mail, with postage prepaid, or
by facsimile transmission during normal business hours, and shall be deemed
sufficiently given if served in a manner specified in this Paragraph 23. The
address noted adjacent to a party's signature on this Lease shall be that
Party's address for delivery or mailing of notice purposes. Either Party may
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.

<PAGE>


         23.3     DATE OF NOTICE. Any notice sent by registered or certified
mail, return receipt requested, shall be deemed given on the date of delivery
shown on the receipt card, or if no delivery date is shown, the postmark
thereon. If sent by regular mail, the notice shall be deemed given
forty-eight (48) hours after the same is addressed as required therein and
mailed with postage prepaid. Notice delivered by United States Express Mail or
overnight courier that guarantees next day delivery shall be deemed given
twenty-four hours after delivery of the same served or delivered upon
telephone or facsimile confirmation of receipt of the transmission thereto,
provided a copy is also delivered via delivery or mail. If notice is received
on a Saturday or a Sunday or a legal holiday, it shall be deemed received on
the next business day.

24.      WAIVERS. No waiver by Lessor or the Default or Breach of any term,
covenant or condition hereof by Lessee, shall be deemed a waiver of any other
term, covenant or condition hereof, or of any subsequent Default or Breach by
Lessee of the same or any other term covenant or condition hereof by Lessee,
shall be deemed a waiver of any other term, covenant or condition hereof, or
of any subsequent Default or Breach by Lessee of the same or any other term,
covenant or condition hereof. Lessor's consent to, or approval of, any such
act shall not be deemed to render unnecessary the obtaining of Lessor's
consent to or approval of, any subsequent or similar act by Lessee, or be
construed as the basis of an estoppel to enforce the provision or provisions
of the 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 money or damages due Lessor, notwithstanding any
qualifying terms or conditions made by Lessee in connection therewith, which
such statements and/or conditions shall be of no force of 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 the 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 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, whenever 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.

30.      SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

         30.1     SUBORDINATION. This Lease and any Option granted hereby
shall be subject to and subordinate to any ground lease, mortgage deed of
trust, or other type 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 not 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 default pursuant to Paragraph 13.5 if any Lender
shall elect to have this Lease and/or any Option granted hereby superior to
the lien of its Security Device and shall give written notice thereof to
Lessee, this Lease and such Options shall be deemed prior to such Security
Device, notwithstanding the relative dates of the documentary or recordation
thereof.

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

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

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

31.      ATTORNEYS' FEES. If any Party brings an action or proceeding to
enforce the term thereof 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 who substantially obtains or
defects the relief sought, as the case may be, whether by compromise,
settlement, judgment, or the abandonment by the other Party of its claim or
defense. The attorneys' fee award shall not be computed by compromise,
settlement, judgment, or the abandonment by the other Party of its claim or
defense. The attorney's 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 subsequently commenced in connection with such Default or resulting
Breach.

32.      LESSOR'S ACCESS: SHOWING PREMISES; REPAIR. 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 with reasonable advance
notice for the purpose of showing the same to prospective purchasers,
lenders, or lessee, 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 item during the last one
hundred eighty (180) days of the term thereof place on or about the Premises
ordinary "For Lease" signs. All such activities of Lessor shall be without
abatement of rent or liability to Lessee.

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

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

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

36.      CONSENTS.

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

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

37.      GUARANTOR.

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

         37.2     ADDITIONAL OBLIGATIONS OF GUARANTOR. It shall constitute a
Default of the Lessee under this Lease if any such Guarantor fails or
refuses, upon reasonable request by Lessor to give: (a) evidence of the due
execution of the guaranty called for by this Lease, including the authority
of the Guarantor (and of the party signing on the Guarantor's behalf) to
obligate such Guarantor on said guaranty, and resolution of its board of
directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signatures of the persons authorized to
sign on its behalf, (b) current financial statements of Guarantor as may from
time to time be requested by Lessor, (c) a Tenancy Statement, or (d) written
confirmation that the guaranty is still in effect.

38.      QUIET POSSESSION. Upon payment by Lessee for 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 or for the entire term
hereof subject to all provisions of this Lease.

by any person or entity other than said original Lessee while the original
Lessee is in full and actual possession of the Premises and without the
intention of thereafter assigning or subletting. The Options, if any, herein
granted to Lessee are not assignable, with a part of an assignment of this
Lease or separately or apart therefrom, and no Option may be separated from
this Lease in any manner, by reservation or otherwise.

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

         39.4     EFFECT OF DEFAULT ON OPTIONS.

                  (a) Lessee shall have no right to exercise an Option,

during the time Lessee is in Breach of this Lease, or (iv) in the event that
Lessor has given to Lessee three (3) or more notices of separate Defaults
under Paragraph 13.1 during the twelve (12) month period immediately
preceding the exercise of the option, whether or not the Defaults are cured.

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

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

way, utility raceways, and dedications that Lessor deems necessary, and to

easements, rights of way, utility raceways, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by

effectuate any such easement rights, dedication, map or restrictions.
