ARTICLE TWO: LEASE TERM

           Section 2.01. LEASE OF PROPERTY FOR LEASE TERM. Landlord leases the
Property to Tenant and Tenant leases the Property from Landlord for the Lease
Term. The Lease Term is for the period stated in Section 1.05 above and shall
begin and end on the dates specified in Section 1.05 above, unless the beginning
or end of the Lease Term is changed under any provision of this Lease. The
"Commencement Date" shall be the date specified in Section 1.05 above for the
beginning of the Lease Term, unless advanced or delayed under any provision of
this Lease.

           Section 2.02. DELAY IN COMMENCEMENT. Landlord shall not be liable to
Tenant if Landlord does not deliver possession of the Property to Tenant on the
Commencement Date. Landlord's non-delivery of the Property to Tenant on that
date shall not affect this Lease or the obligations of Tenant under this Lease
except that the Commencement Date shall be delayed until Landlord delivers
possession of the Property to Tenant and the Lease Term shall be extended for a
period equal to the delay in delivery of possession of the Property to Tenant
and the Lease Term shall be necessary to end the Lease Term on the last day of a
month. If Landlord does not deliver possession of the Property to Tenant within
sixty (60) days after the Commencement Date, Tenant may elect to cancel this
Lease by giving written notice to Landlord within ten (10) days after the sixty
(60) day period ends. If Tenant gives such notice, the Lease shall be canceled
and neither Landlord nor Tenant shall have any further obligations to the other.
If Tenant does not give such notice, Tenant's right to cancel the Lease shall
expire and the Lease Term shall commence upon the delivery of possession of the
Property to Tenant. If delivery of possession of the Property to Tenant is
delayed, Landlord and Tenant shall, upon such delivery, execute an amendment to
this Lease setting forth the actual Commencement Date and expiration date of the
Lease. Failure to execute such amendment shall not affect the actual
Commencement Date and expiration date of the Lease.

           Section 2.03. EARLY OCCUPANCY. If Tenant occupies the Property prior
to the Commencement Date, Tenant's occupancy of the Property shall be subject to
all of the provisions of this Lease. Early occupancy of the Property shall not
advance the expiration date of this Lease. Tenant shall pay Base Rent and all
other charges specified in this Lease for the early occupancy period.

           Section 2.04. HOLDING OVER. Tenant shall vacate the Property upon the
expiration or earlier termination of this Lease. Tenant shall reimburse Landlord
for and indemnify Landlord against all damages which Landlord incurs from
Tenant's delay in vacating the Property. If Tenant does not vacate the Property
upon the expiration or earlier termination of the Lease and Landlord thereafter
accepts rent from Tenant, Tenant's occupancy of the Property shall be a
"month-to-month" tenancy, subject to all of the terms of this Lease applicable
to a month-to-month tenancy, except that the Base Rent then in effect shall be
increased by Twenty-five percent (25%).

SEE RIDER SECTION 2.05.

ARTICLE THREE: BASE RENT

           Section 3.01. TIME AND MANNER OF PAYMENT. Upon execution of this
Lease, Tenant shall pay Landlord the Base Rent in the amount stated in Paragraph
1.12(a) above for the first month of the Lease Term. On the first day of the
second month of the Lease Term and each month thereafter, Tenant shall pay
Landlord the Base Rent, in advance, without offset, deduction or prior demand.
The Base Rent shall be payable at Landlord's address or at such other place as
Landlord may designate in writing.

           Section 3.02. Intentionally omitted.

           Section 3.03. SECURITY DEPOSIT; LETTER OF CREDIT; INCREASES.

           (a) Intentionally Omitted. See Rider Section 3.03.

   4

           (b) Each time the Base Rent is increased after the initial Lease
Term, Tenant shall deposit additional funds with Landlord sufficient to increase
the Letter of Credit to an amount which bears the same relationship to the
adjusted Base Rent as the initial bore to the initial Base Rent.

           Section 3.04. TERMINATION; ADVANCE PAYMENTS. Upon termination of this
Lease under Article Seven (Damage or Destruction), Article Eight (Condemnation)
or any other termination not resulting from Tenant's default, and after Tenant
has vacated the Property in the manner required by this Lease, Landlord shall
refund or credit to Tenant (or Tenant's successor) the unused portion of the
Security Deposit, any advance rent or other advance payments made by Tenant to
Landlord, and any amounts paid for real property taxes and other reserves which
apply to any time periods after termination of the Lease.

ARTICLE FOUR: OTHER CHARGES PAYABLE BY TENANT

           Section 4.01. ADDITIONAL RENT. All charges payable by Tenant other
than Base Rent are called "Additional Rent." Unless this Lease provides
otherwise, Tenant shall pay all Additional Rent then due with the next monthly
installment of Base Rent. The term "rent" shall mean Base Rent and Additional
Rent.

           Section 4.02. PROPERTY TAXES.

           (a) REAL PROPERTY TAXES. Landlord shall pay the "Base Real Property
Taxes" on the Property during the Lease Term. The Annual Base Real Property
Taxes for the Property are Twenty One Thousand One Hundred Forty- Two and 44/100
Dollars ($21,142.44). Tenant shall pay Landlord the amount, if any, by which the
real property taxes during the Lease Term exceed the Base Real Property Taxes.
Subject to Paragraph 4.02(c), Tenant shall make such payments within fifteen
(15) days after receipt of Landlord's statement showing the amount and
computation of such increase. Landlord shall reimburse Tenant for any real
property taxes paid by Tenant covering any period of time prior to or after the
Lease Term.

           (b) DEFINITION OF "REAL PROPERTY TAX." "Real property tax" means: (i)
any fee, license fee, license tax, business license fee, commercial rental tax,
levy, charge, assessment, penalty or tax imposed by any taxing authority against
the Property; (ii) any tax on the Landlord's right to receive, or the receipt
of, rent or income from the Property or against Landlord's business of leasing
the Property; (iii) any tax or charge for fire protection, streets, sidewalks,
road maintenance, refuse or other services provided to the Property by any
governmental agency; (iv) any tax imposed upon this transaction or based upon a
re-assessment of the Property due to a change of ownership, as defined by
applicable law, or other transfer of all or part of Landlord's interest in the
Property; and (v) any charge or fee replacing any tax previously included within
the definition of real property tax. "Real property tax" does not, however,
include Landlord's federal or state income, franchise, inheritance or estate
taxes.

           (c) JOINT ASSESSMENT. If the Property is not separately assessed,
Landlord shall reasonably determine Tenant's share of the real property tax
payable by Tenant under Paragraph 4.02(a) from the assessor's worksheets or
other reasonably available information. Tenant shall pay such share to Landlord
within fifteen (15) days after receipt of Landlord's written statement.

           (d) PERSONAL PROPERTY TAXES.

                     (i) Tenant shall pay all taxes charged against trade
fixtures, furnishings, equipment or any other personal property belonging to
Tenant. Tenant shall try to have personal property taxed separately from the
Property.

                     (ii) If any of Tenant's personal property is taxed with the
Property, Tenant shall pay landlord the taxes for the personal property within
fifteen (15) days after Tenant receives a written statement from Landlord for
such personal property taxes.

           Section 4.03. UTILITIES. Tenant shall pay, directly to the
appropriate supplier, the cost of all natural gas, heat, light, power, sewer
service, telephone, water, refuse disposal and other utilities and services
supplied to the Property. However, if any services or utilities are jointly
metered with other property, Landlord shall make a reasonable determination of
Tenant's proportionate share of the cost of such utilities and services and
Tenant shall pay such share to Landlord within fifteen (15) days after receipt
of Landlord's written statement.



                                       A-3

   5

           Section 4.04. INSURANCE POLICIES.

           (a) LIABILITY INSURANCE. During the Lease Term, Tenant shall maintain
a policy of commercial general liability insurance (sometimes known as broad
form comprehensive general liability insurance) insuring Tenant against
liability for bodily injury, property damage (including loss of use of property)
and personal injury arising out of the operation, use or occupancy of the
Property. Tenant shall name Landlord as an additional insured under such policy.
The initial amount of such insurance shall be One Million Dollars ($1,000,000)
per occurrence and shall be subject to periodic increase based upon inflation,
increased liability awards, recommendation of Landlord's professional insurance
advisers and other relevant factors. The liability insurance obtained by Tenant
under this Paragraph 4.04(a) shall (i) be primary and non-contributing; (ii)
contain cross-liability endorsements; and (iii) insure Landlord against the
negligence of Tenant. The amount and coverage of such insurance shall not limit
Tenant's liability nor relieve Tenant of any other obligation under this Lease.
Landlord may also obtain comprehensive public liability insurance in an amount
and with coverage determined by Landlord insuring Landlord against liability
arising out of ownership, operation, use or occupancy of the Property. The
policy obtained by Landlord shall not be contributory and shall not provide
primary insurance.

           (b) PROPERTY AND RENTAL INCOME INSURANCE. During the Lease Term,
Landlord shall maintain policies of insurance covering loss of or damage to the
Property in the full amount of its replacement value. Such policy shall contain
an Inflation Guard Endorsement and shall provide protection against all perils
included within the classification of fire, extended coverage, vandalism,
malicious mischief, special extended perils (all risk), sprinkler leakage and
any other perils which Landlord deems reasonably necessary. Landlord shall have
the right to obtain flood and earthquake insurance if required by any lender
holding a security interest in the Property. Landlord shall not obtain insurance
for Tenant's fixtures or equipment or building improvements installed by Tenant
on the Property. During the Lease Term, Landlord shall also maintain a rental
income insurance policy, with loss payable to Landlord, in an amount equal to
one year's Base Rent, plus estimated real property taxes and insurance premiums.
Tenant shall be liable for payment of any deductible amount under Landlord's or
Tenant's insurance policies maintained pursuant to this Section 4.04, in an
amount not to exceed Ten Thousand Dollars ($10,000). Tenant shall not do or
permit anything to be done which invalidates any such insurance policies.

           (c) PAYMENT OF PREMIUMS.

                     (i) Landlord shall pay the "Base Premiums" for the
insurance policies maintained by Landlord under Paragraph 4.04(b). Base Premiums
for the Property are Four Hundred Fifty and no/100 Dollars ($450.00) annually.

                     (ii) Tenant shall pay Landlord the amount, if any, by which
the insurance premiums for all policies maintained by Landlord under Paragraph
4.04(b) have increased over the Base Premiums, whether such increases result
from the nature of Tenant's occupancy, any act or omission of Tenant, the
requirement of any lender referred to in Article Eleven (Protection of Lenders),
the increased value of the Property or general rate increases. However, if
Landlord substantially increases the amount of insurance carried or the
percentage of insured value after the period during which the Base Premiums were
calculated, Tenant shall only pay Landlord the amount of increased premiums
which would have been charged by the insurance carrier if the amount of
insurance or percentage of insured value had not been substantially increased by
Landlord. This adjustment in the amount due from Tenant shall be made only once
during the Lease Term. Thereafter, Tenant shall be obligated to pay the full
amount of any additional increases in the insurance premiums, including
increases resulting from any further increases in the amount of insurance or
percentage of insured value. Tenant shall pay Landlord the increases over the
Base Premiums within fifteen (15) days after receipt by Tenant of a copy of the
premium statement or other evidence of the amount due. If the insurance policies
maintained by Landlord cover improvements or real property other than the
Property, Landlord shall also deliver to Tenant a statement of the amount of the
premiums applicable to the Property showing, in reasonable detail, how such
amount was computed. If the Lease Term expires before the expiration of the
insurance period, Tenant's liability shall be pro rated on an annual basis.

           (d) GENERAL INSURANCE PROVISIONS.

           (i) Any Insurance which Tenant is required to maintain under this
Lease shall include a provision which requires the insurance carrier to give
Landlord not less than thirty (30) days' written notice prior to any
cancellation or modification of such coverage.

           (ii) If Tenant fails to deliver any policy, certificate or renewal to
Landlord required under this Lease within the prescribed time period or if any
such policy is canceled or modified during the Lease Term without Landlord's
consent, Landlord may obtain such insurance, in which case Tenant shall
reimburse Landlord for the cost of such insurance within fifteen (15) days after
receipt of a statement that indicates the cost of such insurance.

           (iii) Tenant shall maintain all insurance required under this Lease
with companies holding a "General Policy Rating" of A-12 or better, as set forth
in the most current issue of "Best Key Rating Guide". Landlord and Tenant
acknowledge the insurance markets are rapidly changing and that insurance in the
form and amounts described in this Section 4.04 may not be available in the
future. Tenant acknowledges that the insurance described in this Section 4.04 is
for the primary benefit of Landlord. If at any time during the Lease Term,
Tenant is unable to maintain the insurance required under the Lease, Tenant
shall nevertheless maintain insurance coverage which is customary and
commercially reasonable in the insurance industry for Tenant's type of business,
as that coverage may change from time to time. Landlord makes no representation
as to the adequacy of such insurance to protect Landlord's or Tenant's
interests. Therefore, Tenant shall obtain any such additional property or
liability insurance which Tenant deems necessary to protect Landlord and Tenant.

           (iv) Unless prohibited under any applicable insurance policies
maintained, Landlord and Tenant each hereby waive any and all rights of recovery
against the other, or against the officers, employees, agents or representatives
of the other, for loss of or damage to its property or the property of others
under its control, if such loss or damage is covered by any insurance policy in
force (whether or not described in this Lease) at the time of such loss or
damage. Upon obtaining the required policies of insurance, Landlord and Tenant
shall give notice to the insurance carriers of this mutual waiver of
subrogation.

           Section 4.05. LATE CHARGES. Tenant's failure to pay rent promptly may
cause Landlord to incur unanticipated costs. The exact amount of such costs are
impractical or extremely difficult to ascertain. Such costs may include, but are
not limited to, processing and accounting charges and late charges which may be
imposed on Landlord by any ground lease, mortgage or trust deed encumbering the
Property. Therefore, if Landlord does not receive any rent payment within ten
(10) days after it becomes due, Tenant shall pay Landlord a late charge equal to
ten percent (10%) of the overdue amount. The parties agree that such late charge
represents a fair and reasonable estimate of the costs Landlord will incur by
reason of such late payment.

           Section 4.06. INTEREST ON PAST DUE OBLIGATIONS. Any amount owed by
Tenant to Landlord which is not paid when due shall bear interest at the rate of
fifteen percent (15%) per annum from the due date of such amount. However,
interest shall not be payable on late charges to be paid by Tenant under this
Lease. The payment of interest on such amounts shall not excuse or cure any
default by Tenant under this Lease. If the interest rate specified in this Lease
is higher than the rate permitted by law, the interest rate is hereby decreased
to the maximum legal interest rate permitted by law.

           Section 4.07. IMPOUNDS FOR INSURANCE PREMIUMS AND REAL PROPERTY
TAXES. Tenant is more than ten (10) days late in the payment of rent more than
once in any consecutive twelve (12) month period, Tenant shall pay Landlord a
sum equal to one-twelfth (1/12) of the annual real property taxes and insurance
premiums payable by Tenant under this Lease, together with each payment of Base
Rent. Landlord shall hold such payments in a non-interest bearing impound
account. If unknown, Landlord shall reasonably estimate the amount of real
property taxes and insurance premiums when due. Tenant shall pay any deficiency
of funds in the impound account to Landlord upon written request. If Tenant
defaults under this Lease, Landlord may apply any funds in the impound account
to any obligation then due under this Lease.


                                                                 A-5

ARTICLE FIVE: USE OF PROPERTY

           Section 5.01. PERMITTED USES. Tenant may use the Property only for
the Permitted Uses set forth in Section 1.06 above.

           Section 5.02. MANNER OF USE. Tenant shall not cause or permit the
Property to be used in any way which constitutes a violation of any law,
ordinance, or governmental regulation or order, which annoys or interferes with
the rights of other tenants of Landlord, or which constitutes a nuisance or
waste. Tenant shall obtain and pay for all permits, including a Certificate of
Occupancy, required for Tenant's occupancy of the Property and shall promptly
take all actions necessary to comply with all applicable statutes, ordinances,
rules, regulations, orders and requirements regulating the use by Tenant of the
Property, including the Occupational Safety and Health Act.

           Section 5.03. "Intentionally Omitted". SEE RIDER SECTION 5.03.

           Section 5.04. SIGNS AND AUCTIONS. Tenant shall not place any signs on
the Property without Landlord's prior written consent. Tenant shall not conduct
or permit any auctions or sheriff's sales at the Property.

           Section 5.05. INDEMNITY. Tenant shall indemnify Landlord against and
hold Landlord harmless from any and all costs, claims or liability arising from:
(a) Tenant's use of the Property (b) the conduct of Tenant's business or
anything else done or permitted by Tenant to be done in or about the Property,
including any contamination of the Property or any other property resulting from
the presence or use of Hazardous Material caused or permitted by Tenant; (c) any
breach or default in the performance of Tenant's obligations under this Lease;
(d) any misrepresentation or breach of warranty by Tenant under this Lease; or
(e) other acts or omissions of Tenant. Tenant shall defense Landlord against any
such cost, claim or liability at Tenant's expense with counsel reasonably
acceptable to Landlord or, at Landlord's election. Tenant shall reimburse
Landlord for any legal fees or costs incurred by Landlord in connection with any
such claim. As a material part of the consideration to Landlord, Tenant assumes
all risk of damage to property or injury to persons in or about the Property
arising from any cause, and Tenant hereby waives all claims in respect thereof
against Landlord, except for any claim arising out of Landlord's negligence or
willful misconduct. As used in this Section, the term "Tenant" shall include
Tenant's employees, agents, contractors and invitees, if applicable.

           Section 5.06. LANDLORD'S ACCESS. Landlord or its agents may enter the
Property at all reasonable times to show the Property to potential buyers,
investors or tenants or other parties; to do any other act or to inspect and
conduct tests in order to monitor Tenant's compliance with all applicable
environmental laws and all laws governing the presence and use of Hazardous
Material; or for any other purpose Landlord deems necessary. Landlord shall give
Tenant prior notice of such entry, except in the case of an emergency. Landlord
may place customary "For Sale" or "For Lease" signs on the Property.

           Section 5.07. QUIET POSSESSION. If tenant pays the rent and complies
with all other terms of this Lease, Tenant may occupy and enjoy the Property for
the full Lease Term, subject to the provisions of this Lease.

ARTICLE SIX: CONDITION OF PROPERTY; MAINTENANCE, REPAIRS AND ALTERATIONS

           Section 6.01. EXISTING CONDITIONS. Tenant accepts the Property in its
condition as of the execution of the Lease, subject to all recorded matters,
laws ordinances, and governmental regulations and orders. Except as provided
herein, Tenant acknowledges that neither Landlord nor any agent of Landlord has
made any representation as to the condition of the property or the suitability
of the property for Tenant's intended use. Tenant represents and warrants that
Tenant has made its own inspection of and inquiry regarding the condition of the
Property and is no relying on any representations of Landlord or any Broker with
respect thereto. If Landlord or Landlord's Broker has provided a Property
Information Sheet or other Disclosure Statement regarding the Property, a copy
is attached as an exhibit to the Lease. SEE RIDER SECTION 6.01

           Section 6.02. EXEMPTION OF LANDLORD FROM LIABILITY. Landlord shall
not be liable fr any damage or injury t the person, business (or any loss of
income therefrom), goods, wares, merchandise or other property of Tenant,

Property, whether such damage or injury is caused by or results from (a) fire,
steam electricity, water, gas or rain; (b) the breakage, leakage, obstruction or
other defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures or any other cause; (c)



                                       A-6

   8

conditions arising in or about the Property or from other sources or places; or
(d) any act or omissions of any other tenant of landlord. Landlord shall not be
liable for any such damage or injury even though the cause of or the means of
repairing such damage or injury are not accessible to Tenant. The provisions of
Section 6.02 shall not, however, exempt Landlord from liability for Landlord's
gross negligence or willful misconduct.

           Section 6.03. LANDLORD'S OBLIGATIONS. Subject to the provisions of
Article Seven (Damage or Destruction) and Article Eight (Condemnation), and
except for damage caused by any act or omission of tenant, or tenant's
employees, agents, contractors or invitees, Landlord shall keep the foundation
roof, skylights, and structural portions of exterior walls of the improvements
on the Property in good order, condition and repair. However, Landlord shall not
be obligated to maintain or repair windows, doors, plate glass or the surfaces
of walls, except to the extent such repairs are due to Landlord's negligent
installation. Landlord shall not be obligated to make any repairs under this
Section 6.02 until a reasonable time after receipt of a written notice from
Tenant of the need for such repairs. Tenant waives the benefit of any present or
future law which might give Tenant the right to repair the Property at
Landlord's expense or to terminate the Lease because of the condition of the
Property. SEE RIDER SECTION 6.03

           Section 6.04. TENANT'S OBLIGATIONS.

           (a) Except as provided in Section 6.03 (Landlord's Obligations),
Article Seven (Damage or Destruction) and Article Eight (Condemnation), Tenant
shall keep all portions of the Property (including structural, nonstructural,
interior, exterior, and landscaped areas, portions, systems and equipment) in
good order, condition and repair (including interior repainting and refinishing,
as needed). If any portion of the Property or any system or equipment in the
Property which Tenant is obligated to repair can't be fully repaired or
restored, Tenant shall promptly replace such portion of the Property or system
or equipment in the Property, regardless of whether the benefit of such
replacement extends beyond the Lease Term; but if the benefit or useful life of
such replacement extends beyond the Lease term (as such term may be extended by
exercise of any options), the useful life of such replacement shall be prorated
over the remaining portion of the Lease Term (as extended), and Tenant shall be
liable only for that portion of the cost which is applicable to the Lease Term
(as extended). Tenant shall maintain a preventive maintenance contract providing
for the regular inspection of maintenance of the heating and air conditioning
system by a licensed heating and air conditioning contractor. Landlord shall
have the right, upon written notice to Tenant, to undertake the responsibility
for preventive maintenance of the heating and air conditioning system at
Tenant's expense. In addition, Tenant shall, at Tenant's expense, repair any
damage to the roof, foundation or structural portions of walls caused by
Tenant's acts or omissions. It is the intention of Landlord and Tenant that, at
all times during the Lease Term, Tenant shall maintain the Property in an
attractive, first-class and fully operative condition.

           (b) Tenant shall fulfill all of Tenant's obligations under this
Section 6.04 at Tenant's sole expense. If Tenant fails to maintain, repair or
replace the Property as required by this Section 6.04, Landlord may, upon ten
(10) days' prior notice to Tenant (except that no notice shall be required in

for which Tenant has been reimbursed by the condemning authority. If the
severance damages received by Landlord are not insufficient to pay for such
repair, Landlord shall have the right to either terminate this Lease or make
such repair at Landlord 's expense.

ARTICLE NINE: ASSIGNMENT AND SUBLETTING

           Section 9.01 LANDLORD'S CONSENT REQUIRED. No portion of the Property
or of Tenant's interest in this Lease may be acquired by any other person or
entity, whether by sale, assignment, mortgage, sublease, transfer, operation of
law, or act of Tenant, without Landlord 's prior written consent, except as
provided in Section 9.02 below. Landlord has the right to grant or withhold its
consent as provided in Section 9.05 below. Any attempted transfer without
consent shall be void and shall constitute a non-curable breach of this Lease.
If Tenant is a partnership, any cumulative transfer of more than twenty percent
(20%) of the partnership interests shall require Landlord 's consent. If Tenant
is a corporation, any change in the ownership of a controlling interest of the
voting stock of the corporation shall require Landlord 's consent.

           Section 9.02. TENANT AFFILIATE. Tenant may assign this Lease or
sublease the Property, without Landlord 's consent, to any corporation which
controls, is controlled by or is under common control of Tenant, or to any
corporation resulting from the merger of or consolidation with Tenant ("Tenant's
Affiliate"). In such case, any Tenant's Affiliate shall assume in writing all of

   11

obligations of Tenant under this Lease. Landlord's acceptance of rent from any
other person is not a waiver of any provision of this Article Nine. Consent to
one transfer is not a consent to any subsequent transfer. If Tenant's transferee
defaults under this Lease, Landlord may proceed directly against Tenant without
pursuing remedies against the transferee. Landlord may consent to subsequent
assignments or modifications of this Lease by Tenant's transferee, without
notifying Tenant or obtaining its consent. Such action shall not relieve
Tenant's liability under this Lease.

           Section 9.04 Intentionally omitted.

           Section 9.05. LANDLORD'S CONSENT.

           (a) Tenant's request for consent to any transfer described in Section

other information Landlord deems relevant, Landlord shall have the right to
terminate this Lease or to withhold consent, if reasonable, or to grant consent,
based on the following factors: (i) the business of the proposed assignee or
subtenant and the proposed use of the property; (ii) the net worth and financial
reputation of the proposed assignee or subtenant; (iii) Tenant's compliance with
all of its obligations under the Lease; and (iv) such other factors as Landlord
may reasonable deem relevant. If Landlord objects to a proposed assignment
solely because of the net worth and/or financial reputation of the proposed
assigned, Tenant may nonetheless sublease but not assign, all or a portion of
the Property to the proposed transferee, but only on the other terms of the
proposed transfer.

           (b) If Tenant assigns or subleases, the following shall apply:

           (i) Tenant shall pay to Landlord as Additional Rent under the Lease
the Landlord's share (stated in Section 1.14) of the Profit (defined below) on
such transaction as and when received by Tenant, unless Landlord gives written
notice to Tenant and the assignee or subtenant that Landlord's Share shall be
paid by the assignee or subtenant to Landlord directly. The "Profit" means (A)
all amounts paid to Tenant for such assignment or sublease, including "key"
money, monthly rent in excess of the monthly rent payable under the Lease, and
all fees and other consideration paid for the assignment or sublease, including
fees under any collateral agreements, less (B) cost and expenses directly
incurred by Tenant inc connection with the execution and performance of such
assignment or sublease for real estate broker's commissions and costs of
renovation or construction of tenant improvements required under such assignment
or sublease. Tenant is entitled to recover such cost and expenses before Tenant
is obligated to pay the Landlord's share to Landlord. The Profit in the case of

space as a percentage on a square footage basis.

           (ii) Tenant shall provide Landlord a written statement certifying all
amounts to be paid from any assignment or sublease of the Property within thirty
(30) days after the transaction documentation is signed, and Landlord may
inspect Tenant's books and records to verify the accuracy of such statement. On
written request, Tenant shall promptly furnish to Landlord copies of all the
transaction documentation, all of which shall be certified by Tenant to be
complete, true and correct. Landlord's receipt of Landlord's Share shall not be
a consent to any further assignment or subletting. The breach of Tenant's
obligation under this Paragraph 9.05(b) shall be a material default of the
Lease.

           (c) If Landlord elects to terminate this Lease pursuant to Section
9.05(a), Landlord may, if it elects, enter into a new lease covering the
Property with the intended assignee or sublessee on such terms as Landlord and
such person may agree or enter into a new lease covering the Property with any
other person; in such event, Tenant shall not be entitled to any portion of the
profit, if any, which Landlord may realize on account of such termination and
reletting. From and after the date of such termination of this Lease, Tenant
shall have no further obligation to Landlord hereunder, except for matters
occurring or obligations arising hereunder period to the date of such
termination.

Lease. The notice required by this Paragraph is intended to satisfy any and all
notice requirements imposed by law on Landlord and is not in addition to any
such requirement.

Tenant, Landlord may, at any time thereafter, with or without notice or demand
and without limiting Landlord in the exercise of any right or remedy which
Landlord may have:

lawful means, in which case this Lease shall terminate and Tenant shall
immediately surrender possession of the Property to Landlord. If Tenant shall be
served with a demand for the payment of past due rent or any other charge, any
payments rendered thereafter to cure any default by Tenant shall be made only by
cashier's check. In such event, Landlord shall be entitled to recover from
Tenant all damages incurred by Landlord by reason of Tenant's default, including

which the unpaid Base Rent, Additional rent and other charges which Tenant would
have paid for the balance of the Lease term after the time of award exceeds the
amount of such rental loss the Tenant proves Landlord could have reasonably
avoided; and (iv) any other, amount necessary to compensate Landlord for all the
detriment proximately caused by Tenant;'s failure to perform its obligations
under the Lease or which i n the ordinary course of things would be likely to
result therefrom, including but no limited to, any costs or expenses Landlord
incurs in maintaining or preserving the Property after such default, the cost of

renovation or alteration of the Property. Landlord's reasonable attorney's fees
incurred in connection therewith, and any real estate commission paid or
payable. As used in subparts (i) and (ii) above, the "worth at the time of the
award" is computed by allowing interest on unpaid amounts at the rate of twelve
percent (12%) per annum, or such lesser amount as may then be the maximum lawful
rate. As used in subpart (iii) above, the "wroth at the time of the award" is
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of the award, plus one percent (1%). If Tenant
has abandoned the Property, Landlord shall have the option of (i) retaking
possession of the Property and recovering from Tenant the amount specified in
this Paragraph 10.01(a), or (ii) proceeding under Paragraph 10.03(b). Landlord

Tenant; or the pursuing of any action with respect to Landlord's right to
possession of the Property. All such damages suffered (apart from Base Rent and
other rent payable hereunder ) shall constitute successor to Tenant in any
bankruptcy or other proceeding.

or remedy shall not prevent it from exercising any other right or remedy.

           (a) As used in this Lease, the term "Landlord" means only the current
owner or owners of the fee title to the Property or the leasehold estate under a
ground lease of the Property at the time in question. Each Landlord is obligated
to perform the obligations of Landlord under this Lease only during the time
such Landlord owns such interest or title. Any Landlord who transfers its title
or interest is relieved of all liability with respect to the obligations of
Landlord under this Lease to be performed on or after the date of transfer.
However, each Landlord shall deliver to its transferee all funds that Tenant
previously paid if such funds have not yet been applied under the terms of this
Lease.

           (b) Tenant shall give written notice of any failure by Landlord to
perform any of its obligations under this lease to Landlord and to any ground
lessor, mortgagee or beneficiary under any deed of trust encumbering the
Property whose name and address have been furnished to Tenant in writing.
Landlord shall not be in default under this Lease unless Landlord (or such
ground lessor, mortgagee or beneficiary) fails to cure such non-performance
within thirty (30) days after receipt of Tenant's notice. However, if such
non-performance reasonably requires more than thirty (30) days to cure, Landlord
shall not be in default if such cure is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

           (c) Notwithstanding any term or provision herein to the contrary, the
liability of Landlord for the performance of its duties and obligations under
this Lease is limited to Landlord's interest in the Property, and neither the
Landlord nor its partners, shareholders, officers or other principals shall have
any personal liability under this Lease.

           Section 13.03. SEVERABILITY. A determination by a court of competent

other party.

           Section 13.07. WAIVERS. All waivers must be in writing and signed by
the waiving party. Landlord's failure to enforce any provision of this Lease or
its acceptance of rent shall not be a waiver and shall not prevent Landlord from
enforcing that provision or any other provision of this Lease in the future. No
statement on a payment check from Tenant or in a letter accompanying a payment
check shall be binding on Landlord. Landlord may, with or without notice to
Tenant, negotiate such check without being bound to the conditions of such

                      RIDER TO INDUSTRIAL REAL ESTATE LEASE

           This Rider ("RIDER") is made and entered into by MAJESTIC REALTY CO.
("Majestic") and PATRICIAN ASSOCIATES, INC. ("Patrician"), both California
corporations (collectively, "LANDLORD") and LUMINEX, INC., a California
corporation ("TENANT"), and is dated as of the date set forth on Section 1.01 of
the Industrial Real Estate Lease between Landlord and Tenant ("LEASE") to which
this Rider is attached. The promises, covenants, agreements and declarations
made and set forth herein are intended to and shall have the same force and
effect as if set forth at length in the body of the Lease. To the extent that
the provisions of this Rider are inconsistent with the terms and conditions of
the Lease, the terms and conditions of this Rider shall control.

                                  SECTION 2.05
           TENANT'S ENTRY INTO THE PROPERTY PRIOR TO COMMENCEMENT DATE

           Tenant shall have the right to access of the Property prior to the
Commencement Date for the purpose of installing and/or storing overstandard
equipment or fixtures and preparing the Property for Tenant's use; provided
that: (i) the previous tenant of the Property's lease has expired and/or
terminated, (ii) Tenant and its agents do not interfere with Landlord's work on
the Property, (iii) prior to Tenant's entry into the Property, Tenant shall
submit a schedule to Landlord for approval, which schedule shall detail the
timing and purpose of Tenant's entry and (iv) all of the terms and conditions of
this Lease shall apply, other than Tenant's obligation to pay Base Rent, as
thought he Commencement Date had occurred (although the Commencement Date shall
not actually occur until the occurrence of the same pursuant to the terms of the
third sentence of Section 2.01) upon such entry into the Property by Tenant.
Tenant shall hold Landlord harmless from and indemnify, protect and defend
Landlord against any loss or damage to the Property and against injury to any
persons caused by Tenant's actions or anyone's actions who are directly or
indirectly employed by the Tenant. Tenant shall assume all risk of loss to
Tenant's personal property and fixtures.

                                 SECTION 3.03(A)
                                LETTER OF CREDIT

           A. In General. In lieu of depositing with Landlord a Security
Deposit, Tenant shall deliver to Landlord concurrent with Tenant's execution of
this Lease, an unconditional, clean, irrevocable letter of credit (the "L-C") in
the initial amount of THIRTY-THREE THOUSAND SEVEN HUNDRED FIFTY AND NO/100
DOLLARS ($33,750.00), which L-C shall be issued by a money-center bank (a bank
which accepts deposits, maintains accounts, has a local Los Angeles office which
will negotiate a letter of credit; and whose deposits are insured by the FDIC)
reasonably acceptable to Landlord, and which L-C shall be in a form and content
as set forth in Exhibit F, attached hereto. Tenant shall pay all expenses,
points and/or fees incurred by Tenant in obtaining the L-C.

           B. Application of the L-C. The L-C shall be held by Landlord as
security for the faithful performance by Tenant of all the terms, covenants, and
conditions of this Lease to be kept and performed by Tenant during the Lease
Term. The L-C shall not be mortgaged, assigned or encumbered in any manner
whatsoever by Tenant without the prior written consent of Landlord. If Tenant
defaults with respect to any provisions of this Lease, including, but not
limited to, the provisions relating to the payment of rent, or if Tenant fails
to renew the L-C at least thirty (30) days before its expiration, Landlord may,
but shall not be required to, draw upon all or any portion of the L-C for
payment of any rent or any other sum in default, or for the payment of any
amount that Landlord may reasonably spend or may become obligated to spend by
reason of Tenant's default, or to compensate Landlord for any other loss or
damage that Landlord may suffer by reason of Tenant's default. The use,
application or retention of the L-C, or any portion thereof, by Landlord shall
not prevent Landlord from exercising any other right or remedy provided by this
Lease or by law, it being intended that Landlord shall not first be required to
proceed against the L-C and shall not operate as a limitation on any recovery to
which Landlord may otherwise be entitled. Any amount of the L-C which is drawn
upon by Landlord, but is not used or applied by Landlord, shall be held by
Landlord and deemed a security deposit (the "L-C Security Deposit"). If any
portion of the L-C is drawn upon, Tenant shall, within five (5) days after
written demand therefor, either (i) deposit cash with Landlord (which cash shall
be applied by Landlord to the L-C Security Deposit) in an amount sufficient to
cause the sum of the L-C Security Deposit and the amount of the remaining L-C to
be equivalent to the amount of the L-C then required under this Lease or (ii)
reinstate the L-C to the amount then required under this Lease, and if any
portion of the L-C Security Deposit is used or applied, Tenant shall, within
five (5) days after written demand therefor, deposit cash with Landlord (which
cash shall be applied by Landlord to the L-C Security Deposit) in an amount
sufficient to restore the L-C Security Deposit to the amount then required under
this Lease, and Tenant's failure to do



                                 RIDER - Page 1

   20

so shall be a default under this Lease. Tenant acknowledges that Landlord has
the right to transfer or mortgage its interest in the Property and in this Lease
and Tenant agrees that in the event of any such transfer or mortgage, Landlord
shall have the right to transfer or assign the L-C Security Deposit and/or the
L-C to the transferee or mortgagee, and in the event of such transfer, Tenant
shall look solely to such transferee or mortgagee for the return of the L-C
Security Deposit and or the L-C. If the Tenant has not been in default under
this Lease, the amount of the L-C shall, on the first (1st) and second (2nd)
anniversary of the Lease Commencement Date, be reduced by an amount equal to
ELEVEN THOUSAND TWO HUNDRED AND FIFTY AND NO/100 DOLLARS ($11,250.00). If Tenant
performs every provision of this Lease, the L-C Security Deposit and/or the L-C,
or any balance thereof, shall be returned to Tenant within sixty (60) days
following the expiration or termination of the Lease.

suffer any Hazardous Material to be brought upon, treated, kept, stored,
disposed of, discharged, released, produced, manufactured, generated, refined or
used upon, about or beneath the Property by The Tenant Group, or any other
person without the prior written consent of Landlord. From time to time during

of other Hazardous Materials, which approval may be withheld in Landlord's sole
discretion. Tenant shall, prior to the Commencement Date, provide to Landlord
for those Hazardous Materials described on Exhibit "D" (a) a description of
handling, storage, use and disposal procedures, and (b) all "community right to
know" plans or disclosures and/or emergency response plans which Tenant is

Amendments and Reauthorization Act of 1986 (42 U.S.C. section 9607(l)) or any
similar state statute.

           D. Tenant shall not install, operate or maintain any above or below
grade tank, sump, pit, pond, lagoon or other storage or treatment vessel or

5.03.3 INDEMNITY.

           A. Tenant, its successors, assigns and guarantors, agree to
indemnify, defend, reimburse and hold harmless:

                     (i) Landlord; and

                     (ii) any other person who acquires all or a portion of the
Property in any manner (including purchase at a foreclosure sale) or who becomes
entitled to exercise the rights and remedies of Landlord under this Lease; and

                     (iii) the directors, officers, shareholders, employees,
partners, agents, contractors, subcontractors, experts, licensees, affiliates,
lessees, mortgagees, trustees, heirs, devisees, successors, assigns and invitees
of such persons, from and against any and all Environmental Damages which exist
as a result of the activities or negligence of The Tenant Group or which exist
as a result of the breach of any warranty or covenant or the inaccuracy of any
representation of Tenant contained in this Lease, or by Tenant's remediation of
the Property or failure to meet its remediation obligations contained in this
Lease.

           B. The obligations contained in this Section 5.03 shall include, but
not be limited to, the burden and expense of defending all claims, suits and
administrative proceedings, even if such claims, suits or proceedings are
groundless, false or fraudulent, and conducting all negotiations of any
description, and paying and discharging, when and as the same become due, any
and all judgments, penalties or other sums due against such indemnified persons.
Landlord, at its sole expense, may employ additional counsel of its choice to
associate with counsel representing Tenant.

           C. Landlord shall have the right but not the obligation to join and
participate in, and control, if it so elects, any legal proceedings or actions
initiated in connection with Tenant's activities. Landlord may also negotiate,
defend, approve and appeal any action taken or issued by any applicable
governmental authority with regard to contamination of the Property by a
Hazardous Material.

           D. The obligations of Tenant in this paragraph shall survive the
expiration or termination of this Lease.

           E. The obligations of Tenant under this paragraph shall not be
affected by any investigation by or on behalf of Landlord, or by any information
which Landlord may have or obtain with respect thereto.

5.03.4 OBLIGATION TO REMEDIATE.

           In addition to the obligation of Tenant to indemnify Landlord
pursuant to this Lease, Tenant shall, upon approval and demand of Landlord, at
its sole cost and expense and using contractors approved by Landlord, promptly
take all actions to remediate the Property which are required by any
Governmental Agency, or which are reasonably necessary to mitigate Environmental
Damages or to allow full economic use of the Property, which remediation is
necessitated from the presence upon, about or beneath the Property, at any time
during or upon termination of this Lease, of a Hazardous Material or a violation
of Environmental Requirements existing as a result of the activities or
negligence of the Tenant Group. Such actions shall include, but not be limited
to, the investigation of the environmental condition of the Property, the
preparation of any feasibility studies, reports or remedial plans, and the
performance of any cleanup, remediation, containment, operation, maintenance,
monitoring or restoration work, whether on or off the Property,



                                 RIDER - Page 4

   23

which shall be performed in a manner approved by Landlord. Tenant shall take all
actions necessary to restore the Property to the condition existing prior to the
introduction of Hazardous Material upon, about or beneath the Property,
notwithstanding any lesser standard of remediation allowable under applicable
law or governmental policies. Notwithstanding the foregoing, Tenant shall have
no obligation to remediate the Property if the Environmental Damages are a
direct result of the actions of a previous occupant of the Property or a
previous or present occupant or owner of any adjoining or neighboring
properties.

5.03.5 RIGHT TO INSPECT.

           Landlord shall have the right in its sole and absolute discretion,
but not the duty, to enter and conduct an inspection of the Property, including
invasive tests, at any reasonable time to determine whether Tenant is complying
with the terms of the Lease, including but not limited to the compliance of the
Property and the activities thereon with Environmental Requirements and the
existence of Environmental Damages as a result of the condition of the Property
or surrounding properties and activities thereon. Landlord shall have the right,
but not the duty, to retain any independent professional consultant (the
"Consultant") to enter the Property to conduct such an inspection or to review
any report prepared by or for Tenant concerning such compliance. The cost of the
Consultant shall be paid by Landlord unless such investigation discloses a
violation of any Environmental Requirement by The Tenant Group or the existence
of a Hazardous Material on the Property or any other property caused by the
activities or negligence of The Tenant Group (other than Hazardous Materials
used in compliance with all Environmental Requirements and previously approved
by Landlord), in which case Tenant shall pay the cost of the Consultant. Tenant
hereby grants to Landlord, and the agents, employees, consultants and
contractors of Landlord the right to enter the Property and to perform such
tests on the Property as are reasonably necessary to conduct such reviews and
investigations. Landlord shall use its best efforts to minimize interference
with the business of Tenant.

5.03.6 NOTIFICATION.

           If Tenant shall become aware of or receive notice or other
communication concerning any actual, alleged, suspected or threatened violation
of Environmental Requirements, or liability of Tenant for Environmental Damages
in connection with the Property or past or present activities of any person
thereon, including but not limited to notice or other communication concerning
any actual or threatened investigation, inquiry, lawsuit, claim, citation,
directive, summons, proceeding, complaint, notice, order, writ, or injunction,
relating to same, then Tenant shall deliver to Landlord within ten (10) days of
the receipt of such notice or communication by Tenant, a written description of
said violation, liability, or actual or threatened event or condition, together
with copies of any documents evidencing same. Receipt of such notice shall not
be deemed to create any obligation on the part of Landlord to defend or
otherwise respond to any such notification.

           If requested by Landlord, Tenant shall disclose to Landlord the names
and amounts of all Hazardous Materials other than general office supplies
referred to in Section 5.03.2 of this Rider, which were used, generated,
treated, handled, stored or disposed of on the Property or which Tenant intends
to use, generate, treat, handle, store or dispose of on the Property, for the
year prior to and after such Disclosure Date. The foregoing in no way shall
limit the necessity for Tenant obtaining Landlord's consent pursuant to Section
5.03.2 of this Rider.

5.03.7 SURRENDER OF PREMISES.

           In the ninety (90) days prior to the expiration or termination of the
Lease Term, and for up to ninety (90) days after Tenant fully surrenders
possession of the Property, Landlord may have an environmental assessment of the
Property performed in accordance with Section 5.03.5 of this Rider, at
Landlord's sole cost and expense; provided however if the environmental
assessment reveals any Environmental Damages, then Tenant, upon demand from
Landlord, shall reimburse Landlord for the full cost of the environmental
assessment. Tenant shall perform, at its sole cost and expense, any clean-up or
remedial work recommended by the Consultant which is necessary to remove,
mitigate or remediate any Hazardous Materials and/or contamination of the
Property caused by the activities or negligence of The Tenant Group.

5.03.8 ASSIGNMENT AND SUBLETTING.

           In the event the Lease provides that Tenant may assign the Lease or
sublet the Property subject to Landlord's consent and/or certain other
conditions, and if the proposed assignee's or sublessee's activities in or about
the Property involve the use, handling, storage or disposal of any Hazardous
Materials other than those used by Tenant and in quantities and processes
similar to Tenant's uses in compliance with the Rider, (i) it shall be
reasonable for Landlord to withhold its consent to such assignment or sublease
in light of the risk of contamination posed by such activities and/or (ii)
Landlord may impose an additional condition to such assignment or sublease which
requires Tenant to reasonably establish that such assignee's or sublessee's
activities pose no materially greater risk of contamination to the Property than
do Tenant's permitted activities in view of the (a) quantities, toxicity and
other properties of the Hazardous Materials to be used by such assignee or
sublessee, (b) the precautions against a release of Hazardous Materials such
assignee or sublessee agrees to implement, (c) such assignee's or sublessee's
financial condition as it relates to its ability to fund a major clean-up and
(d) such assignee's or sublessee's policy and historical record respecting its
willingness to respond to the clean up of a release of Hazardous Materials.

5.03.9 SURVIVAL OF HAZARDOUS MATERIALS OBLIGATION.

           Tenant's breach of any of its covenants or obligations under this
Rider shall constitute a material default under the Lease. The obligations of
Tenant under this Rider shall survive the expiration or earlier termination of
the Lease without any limitation, and shall constitute obligations that are
independent and severable from Tenant's covenants and obligations to pay rent
under the Lease.

                                  ARTICLE SIX:
                             CONDITION OF PROPERTY:

SECTION 6.01 EXISTING CONDITIONS

           Section 6.01 of the Lease is hereby amended by adding the following
at the end thereof:

          "Notwithstanding the foregoing, the improvements on the
          Property on such date as this Lease is fully executed and
          delivered (the "Lease Date") shall comply with all
          applicable covenants and restrictions of record and any
          building codes, regulations and ordinances in effect upon
          the Lease Date ("Applicable Laws") whether such codes,
          regulations and ordinances are federal, state or local. If
          the improvements on the Property as of the Lease Date do
          not comply with Applicable Laws, except to the extent such
          Applicable Laws are required due to Tenant's use of the
          Property or any alterations made by Tenant, then Landlord
          shall promptly after receipt of written notice from Tenant
          setting forth with specificity the nature and extent of
          noncompliance, rectify the same at Landlord's expense. If
          Tenant fails to give Landlord such written notice of
          noncompliance within thirty (30) days following the Lease
          Date, correction of that noncompliance shall be the
          obligation of Tenant at Tenant's sole cost and expense."

SECTION 6.03 LANDLORD'S OBLIGATIONS:

           Section 6.03 of the Lease is hereby amended by adding the following
at the end thereof:

          "Notwithstanding the foregoing, Landlord shall, at
          Landlord's expense, repair the existing plumbing,
          electrical, air conditioning, fire sprinkler\alarm system,
          heating, loading doors and ventilating systems in the
          Property, if such are not in good operating condition on
          the Lease Date, except to the extent such repairs are
          required due to the negligence or willful misconduct of
          Tenant; provided, however that Tenant gives Landlord
          written notice and sets forth with specificity the nature
          and extent of such repair, within thirty (30) days
          following the Lease Date."

SECTION 7.05 SUBSTANTIAL OR TOTAL DESTRUCTION:

           Notwithstanding anything to the contrary contained in this Lease, if
there is total or substantial destruction to the Property and the repair of
which actually takes a period beyond that date which is six (6) months after
Tenant's notice of the occurrence of the total or substantial destruction (the
"Outside Date"), then Tenant may, at Tenant's option, terminate this Lease by
delivering written notice of such termination to Landlord, no later than thirty
(30) days after the Outside Date. Notwithstanding anything to the contrary
contained in this Lease, if there is total or substantial destruction to the
Property, Tenant shall have the right, at any time and from time to time to
require Landlord to deliver to Tenant a written notice (the "Contractor
Certificate") certifying to both Landlord and Tenant, in the reasonable opinion
of Landlord's contractor, the amount of time required to repair or complete the
repair of the destruction to the Property. If the contractor in the Contractor
Certificate certifies that the repair of the destruction to the Property will
take a period in excess of six (6) months from receipt of Tenant's request, then
within fifteen (15) days after the delivery of the Contractor Certificate to
Tenant, Tenant may, at Tenant's option, terminate this lease by delivering
written notice of such termination to Landlord within such fifteen (15) day
period. Notwithstanding the foregoing, Tenant shall not have any right to
terminate this Lease under this Section 7.05 if the damage to the Property was
caused by an act or omission of Tenant.

                                ARTICLE FIFTEEN:
                             LANDSCAPE MAINTENANCE:

           Notwithstanding the provisions of Sections 6.03 and 6.04, Landlord
shall maintain, at Tenant's expense, the landscaping of the Property and, if
applicable, the common areas. Such maintenance shall include gardening, tree
trimming, replacement or repair of landscaping, landscape irrigation systems and
similar items. Such maintenance shall also include sweeping and cleaning of
asphalt, concrete or other surfaces on the driveway, parking areas, yard areas,
loading areas or other paved or covered surfaces. In connection with Landlord's
obligations under this Article, Landlord may enter into a contract with a
landscape contractor of Landlord's choice to provide some (but not necessarily
all) of the maintenance services listed above. Tenant's monthly cost of such
contract, hereinafter referred to as the "Landscape Fee" is currently FOUR
HUNDRED NINETY AND NO/100 DOLLARS ($490.00). Landlord shall use its best efforts
to maintain competitive contracts and shall promptly notify Tenant of any
increase in the Landscape Fee. Tenant agrees to pay monthly to Landlord, as
additional rent, the Landscape Fee. Tenant shall make such payment together with
Tenant's monthly rental payment, without the necessity of notice from Landlord.
It is the understanding of the parties that the Landscape Fee only pertains to
routine landscape maintenance on the Property and that Landlord may incur
expenses in addition to the Landscape Fee in meeting its obligations set forth
above. Tenant shall pay to Landlord, as additional rent, within ten (10) days
after demand therefore, the cost of such additional expenses.

                                 ARTICLE SIXTEEN
                         REVENUE AND EXPENSE ACCOUNTING

           Landlord and Tenant agree that, for all purposes (including any
determination under Section 467 of the Internal Revenue Code), rental income
will accrue to the Landlord and rental expenses will accrue to the Tenant in the
amounts and as of the dates rent is payable under the Lease.

                                ARTICLE SEVENTEEN
                                RELOCATION OPTION

           Landlord hereby grants the Tenant named in Section 1.03 (the
"ORIGINAL TENANT") during the initial Lease Term, to substitute for the Property
another Landlord owned property, containing not less than one hundred twenty
percent (120%) of the rentable square footage of the original Property (the
"RELOCATION SPACE"), which Relocation Space thereafter shall be deemed to be the
Property demised by this Lease. Notwithstanding the foregoing, such relocation
right shall be subordinate to all rights of existing and future tenants of
Landlord to lease the Relocation Space (whether or not pursuant to presently
existing rights of first offer, expansion options, must-take requirements,
renewal, relocation or otherwise, whether or not such rights are pursuant to an
express written provision in the lease of any such tenant, and regardless of
whether any such lease of the Relocation Space is consummated pursuant to a
lease amendment or a new lease) (collectively, the "SUPERIOR RIGHT HOLDER"),
with respect to such Relocation Space. Tenant's right of relocation shall be on
the terms and conditions set forth in this Article 17. Tenant shall pay the
out-of-pocket expenses reasonably incurred by Landlord in connection with such
substitution of the Property, and Landlord shall have no



                                 RIDER - Page 7

   26

liability to Tenant for any loss incurred by Tenant as a result of the
interruption of the conduct of Tenant's business or for expenses incurred by
Tenant in connection with such relocation.

           17.1 Exercise of Option. The option contained in this Article 17
shall be exercised by the Original Tenant, if at all, and only in the following
manner: (i) Tenant shall deliver written notice to Landlord (the "RELOCATION
NOTICE"), stating that (a) Tenant is interested in exercising its option to
relocate pursuant to the terms of this Article 17, (b) Tenant's square footage
requirement (which shall not be less than a 30,000 square feet industrial
building) and (c) the geographical area to which Tenant desires to relocate (the
"TENANT'S REQUIREMENTS") and (ii) within fifteen (15) business days of
Landlord's receipt of the Relocation Notice, Landlord shall notify Tenant
("LANDLORD'S LEASE NOTICE") with respect to the availability of any Landlord
owned property that meets Tenant's Requirements during the period from the date
of Landlord's receipt of the Relocation Notice through the date which is thirty
(30) days following the date of Landlord's receipt of the Relocation Notice. The
Landlord's Notice shall describe the space so offered to Tenant and shall set
forth the economic and noneconomic terms and conditions upon which Landlord is
willing to lease such space to Tenant. For purposes hereof, space shall not be
considered to be available for lease by Tenant hereunder at any time that
Landlord has delivered a lease proposal or a lease document regarding the
subject space to a prospective or existing tenant and Landlord and such
prospective or existing tenant are participating in ongoing negotiations
concerning the lease of such space or if such space is subject to a Superior
Right Holder. Within thirty (30) days of Tenant's receipt of Landlord's Lease
Notice (the "NEGOTIATION PERIOD"), Landlord and Tenant shall attempt to agree
upon mutually acceptable "Relocation Rent," as that term is defined in Section
17.3 of this Lease. If Landlord and Tenant fail to reach agreement within the
Negotiation Period, then the relocation option shall be void and of no further
force or effect.

           17.2 Procedure for Acceptance. Upon the agreement of Landlord and
Tenant of the Relocation Rent during the Negotiation Period, Tenant shall
exercise its relocation right with respect to the Relocation Space by delivering
notice to Landlord of Tenant's irrevocable intention to relocate with respect to
all, but not less than all, of any available space as then currently demised (
the "TENANT'S ACCEPTANCE NOTICE"). If Tenant does not timely deliver to Landlord
any notice as set forth in this Article 17 or fails to meet the other
requirements set forth in this Article 17, then Tenant shall be deemed to have
elected not to relocate and Landlord shall be free to lease the space(s)
described in the Landlord's Notice to anyone to whom Landlord desires on any
terms Landlord desires.

           17.3 Relocation Rent. The Base Rent for the Relocation Space payable
by Tenant upon the "Relocation Space Commencement Date," as that term is defined
in Section 17.5, shall be equal to such rent mutually agreed upon by Landlord
and Tenant during the Negotiation Period. Tenant shall also be obligated to pay
the Additional Rent for the Relocation Space. The Base Rent and Additional Rent
for the Relocation Space shall be known herein collectively as the "RELOCATION
RENT". In no event shall Landlord be obligated to provide or consider any tenant
improvement or other allowances or concessions in connection with the Relocation
Rent for the Relocation Space.

           17.4 Construction in The Relocation Space. Tenant shall take the
Relocation Space in its "as is" condition, and Landlord shall not be obligated
to provide or pay for any improvement work or serviced related to the
improvement of the Relocation Space. The construction of improvements in the
Relocation Space shall comply with the terms of Section 6.05 of this Lease.

           17.5 Amendment to Lease. If Tenant timely exercises Tenant's right to
relocate as set forth herein, Landlord and Tenant shall within fifteen (15) days
thereafter execute an amendment to this Lease upon the terms and condition set
forth in this Article 17. Tenant shall deposit with Landlord, concurrently with
Tenant's execution and delivery of the amendment to Landlord, cash in an amount
equal to the additional monthly Base Rent, which amount shall be held as part of
the Security Deposit. Tenant shall commence payment of the Relocation Rent for
the Relocation Space and the term of the lease of the Relocation Space
("RELOCATION TERM") shall commence upon the date of delivery of the Relocation
Space to Tenant (the "RELOCATION SPACE COMMENCEMENT DATE"). Notwithstanding the
amount of time remaining in the Lease Term, the Relocation Term shall be at
least five (5) years. Before the Relocation Space Commencement Date Tenant shall
vacate, surrender and deliver exclusive possession of the initial Property to
Landlord in accordance with the provisions of this Lease as set forth in Section
6.06 of this Lease. In the event that Tenant retains possession of the initial
Property or any part thereof after the Relocation Space Commencement Date, then
the provision of Section 2.04 of this Lease shall apply.

           17.6 Termination of Relocation Right. The rights contained in this
Article 17 shall be personal to the Original Tenant, and may only be exercised
by Tenant (and not any assignee, sublessee or other transferee of



                                 RIDER - Page 8

   27

Tenant's interest in this Lease) if Tenant occupies the entire Property. Tenant
shall not have the right to lease the Relocation Space, as provided in this
Section 17, if, as of the date of the attempted exercise of any relocation right
by Tenant, or as of the scheduled date of delivery of such Relocation Space to
Tenant, Tenant is in default under this Lease or Tenant has previously been in
default under this Lease on more than three (3) times during the Lease Term.

                                   LEASE RIDER


           This Rider is attached to and made part of that certain Lease (the

ASSOCIATES, Inc., both as California corporations, collectively as Landlord, and
Luminex, Inc., a California corporation , as Tenant, covering the Property
commonly known as 13710 Ramona Avenue, Chino, California (the "Property"). The
terms used herein shall have the same definitions as set forth in the Lease. The
provisions of this Rider shall supersede any inconsistent and conflicting
provisions of the Lease.

A. OPTION(S) TO EXTEND TERM.

           1. Landlord hereby grants to Tenant two (2) option(s) (the
"Option(s)") to extend the Lease Term for additional term(s) of three (3) years
each (the "Extension(s)"), on the same terms and conditions as set forth in the
Lease, but at an increased rent as set forth below. Each Option shall be
exercised only by written notice delivered to Landlord at least one hundred
eighty (180) days before the expiration of the Lease Term or the preceding
Extension of the Lease Term, respectively. If Tenant fails to deliver Landlord
written notice of the exercise f an Option within the prescribed time period,
such Option and any succeeding Options shall lapse, and there shall be no
further right to extend the Lease Term. Each Option shall be exercisable by
Tenant on the express conditions that (a) at the time of the exercise, and at
all times prior to the commencement of such Extension, Tenant shall not be in
default under any of the provisions of this Lease and (b) Tenant has not been
more than ten (10) days late in the payment of rent more than a total of two (2)
times during any twelve (12) month period of the Lease Term and all preceding

           The Option(s) are personal to the Tenant named in Section 1.03 of the
Lease, any Tenant's affiliate described in Section 9.02 of the Lease or any
entity which purchases all the stock of Tenant and all or substantially all of
Tenant's assets ("Tenant Purchaser"). If Tenant subleases any portion of the
Property or assigns or otherwise transfers any interest under the Lease to any
entity other than a Tenant Affiliate prior to the exercise of an Option (whether
with or without Landlord's consent), such Option and any succeeding Options
shall lapse. If Tenant subleases any portion of the Property or assigns or
otherwise transfers any interest of Tenant under the Lease to any entity other
than a Tenant Affiliate or Tenant Purchaser after the exercise of an Option but
prior to the commencement of the respective Extension (whether with or without
Landlord's consent), such Option and any succeeding Options shall lapse and the
Lease Term shall expire as if such Option were not exercised. If Tenant
subleases any portion of the Property or assigns or otherwise transfers any
interest of Tenant under the Lease in accordance with Article 9 of the Lease
after the exercise of an Option and after the commencement of the Extension
during which such sublease or transfer occurred and only the succeeding Options
shall lapse.

(INDICATE YOUR CHOICE UPON EXECUTION OF THE LEASE):

                             Appraisal by Brokers. X

           (b) If Landlord and Tenant are not able to agree upon the fair rental

sixty-five (65) days prior to the applicable Rental Adjustment Date. Within ten
(10) days thereafter, the two appointed appraisers/brokers shall appoint a third
appraiser or broker, as indicated above. If either Landlord or Tenant fails to
appoint its appraiser/broker within the prescribed time period, the single
appraiser/broker appointed shall determine the fair rental value of the
Property. If both parties fail to appoint appraisers/brokers within the
prescribed time periods, then the first appraiser/ broker thereafter selected by
to a party shall determine the fair rental value of the Property. Each party
shall bear the cost of its own appraiser or broker and the parties shall share
equally the cost of the single or third appraiser or broker, if applicable. If
appraisers are used, such appraisers shall have at least five (5) years
experience in the appraisal of commercial/industrial real property in the area
in which the Property is located and shall be members of professional
organizations such as MAI or equivalent. If brokers are used, such brokers shall
have at least five (5) years experience in the sales of leasing of
commercial/industrial real property in the area in which the Property is located
and shall be members of professional organizations such as the Society of
Industrial Realtors or equivalent.

           (c) For the purposes of such appraisal, the term "fair market value"
shall mean the price that a ready and willing tenant would pay, as of the
applicable Rental Adjustment Date, as monthly rent to a ready and willing
Landlord of property comparable to the Property if such property were exposed
for lease on the open market for a reasonable period of time and taking into
account all of the purposes for which such property may be used. If a single
appraiser/broker is chosen, then such appraiser/broker shall determine the fair
rental value of the Property. Otherwise, the fair rental value of the Property
shall be the arithmetic average of two (2) of the three (3) appraisals which are
closest in amount, and the third appraisal shall be disregarded. In no event,
however, shall the Base Rent be reduced by reason of such computation. Landlord
and Tenant shall instruct the appraiser(s)/broker(s) to complete their
determination f the faire rental value not later than thirty (30) days prior to
the applicable Rental Adjustment Date. If the fair rental value is not
determined prior to the applicable Rental Adjustment Date, then Tenant shall
continue to pay to Landlord the Base Rent applicable to the Property immediately
prior to such Extension, until the fair rental value is determined. When he fair
rental value of the Property is determined, Landlord shall deliver notice
thereof to Tenant, and Tenant shall pay to Landlord, within (1) day after
receipt of such notice, the difference between the Base Rent actually paid by
Tenant to Landlord and the new Base Rent determined hereunder.

           3. FIXED ADJUSTMENT. Intentionally omitted.

payment based on non-compliance of any work with the "Approved Working
Drawings," as that term is defined in Section 3.4 below, or due to any

the Tenant Improvements must at a minimum comply with the applicable

Specifications as designated by Landlord. Landlord may make changes to the
Standard Improvement Package from time to time. Tenant's noncompliance with the
Standard Improvement Package shall constitute a material default under this
Lease.

                                    SECTION 3
                              CONSTRUCTION DRAWINGS

           3.1 Selection of Architect/Construction Drawings. Tenant shall retain
an architect (the "Architect") and engineers (the "Engineers"), with at least
five (5) years experience and whom shall be approved by Landlord, to prepare the
plans and drawings (the "Construction Drawings"). The Engineers shall prepare
all plans and engineering working drawings relating to the structural,
mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work in the
Property. All Construction Drawings shall comply with Landlord's drawing format
and specifications and shall be subject to Landlord's approval. Tenant and
Architect shall verify, in the field, the dimensions and conditions as shown on
the relevant portions of the base building plans, and Tenant and Architect shall
be solely responsible for the same, and Landlord shall have no responsibility in
connection therewith. Landlord's review of the Construction Drawings as set
forth in this Section 3, shall be for its sole purpose and shall not imply
Landlord's review of the same, or obligate Landlord to review the same, for
quality, design, Code compliance or other like matters. Accordingly,
notwithstanding that any Construction Drawings are reviewed by Landlord or its
space planner, architect, engineers and consultants, and notwithstanding any
advice or assistance which may be rendered to Tenant by Landlord or Landlord's
space planner, architect, engineers, and consultants, Landlord shall have no
liability whatsoever in connection therewith and shall not be responsible for
any omissions or errors contained in the Construction Drawings, and Tenant's
waiver and indemnity set forth in Section 5.05 of this Lease shall specifically
apply to the Construction Drawings.

           3.2 Final Space Plan. Tenant shall supply Landlord with four (4)
copies signed by Tenant of its final space plan for the Property before any
architectural working drawings or engineering drawings have been commenced. The
final space plan (the "Final Space Plan") shall include a layout and designation
of all offices, rooms and other partitioning, their intended use, and equipment
to be contained therein. Landlord may request clarification or more specific
drawings for special use items not included in the Final Space Plan. Landlord
shall advise Tenant within three (3) business days after Landlord's receipt of
the Final Space Plan for the Property if the same is unsatisfactory or
incomplete in any respect. If Tenant is so advised, Tenant shall promptly cause
the Final Space Plan to be revised to correct any deficiencies or other matters
Landlord may reasonably require.

           3.3 Final Working Drawings. After the Final Space Plan has been
approved by Landlord, Tenant shall promptly cause the Architect and the
Engineers to complete the architectural and engineering drawings for the
Property, and Architect shall compile a fully coordinated set of architectural,
structural, mechanical, electrical and plumbing working drawings in a form which
is complete to allow subcontractors to bid on the work and to obtain all
applicable permits (collectively, the "Final Working Drawings") and shall submit
the same to Landlord for Landlord's approval. Tenant shall supply Landlord with
four (4) copies signed by Tenant of such Final Working Drawings. Landlord shall
advise Tenant within three (3) business days after Landlord's receipt of the
Final Working Drawings for the Property if the same is unsatisfactory or
incomplete in any respect. If Tenant is so advised, Tenant shall immediately
revise the Final Working Drawings in accordance with such review and any
disapproval of Landlord in connection therewith.

           3.4 Approved Working Drawings. The Final Working Drawings shall be
approved by Landlord (the "Approved Working Drawings") prior to the commencement
of construction of the Property by Tenant. After approval by Landlord of the
Final Working Drawings, Architect shall submit the same to the City in which the
Property is located for all applicable building permits. Tenant hereby agrees
that neither Landlord nor Landlord's consultants shall be responsible for
obtaining any building permit or certificate of occupancy for the Property and
that obtaining the same shall be Tenant's responsibility; provided, however,
that Landlord shall cooperate with Tenant in executing permit applications and
performing other ministerial acts reasonably necessary to enable Tenant to
obtain any such permit or



                               EXHIBIT E - Page 3

   37

certificate of occupancy. No changes, modifications or alterations in the
Approved Working Drawings may be made without the prior written consent of
Landlord, which consent may not be unreasonably withheld.

                                    SECTION 4
                     CONSTRUCTION OF THE TENANT IMPROVEMENTS

           4.1 Tenant's Selection of Contractors. Tenant shall retain a licensed
general contractor with at least five (5) years experience as a licensed general
contractor in good standing, and who is bondable (the "Contractor"), as
contractor for the construction of the Tenant Improvements, which Contractor
shall be approved by Landlord. The Contractor and all subcontractors shall be
licensed by the Department of Consumer Affairs Contractors State License Board,
State of California.

           4.2 Construction of Tenant Improvements by Tenant's Agents.

                     4.2.1 Construction Contract; Cost Budget. Prior to Tenant's
execution of the construction contract and general conditions with Contractor
(the "Contract"), Tenant shall submit the Contract to Landlord for its approval,
which approval shall not be unreasonably withheld or delayed. The Tenant shall
cause the Contract to include a copy of the Specifications. Prior to the
commencement of the construction of the Tenant Improvements, and after Tenant
has accepted all bids for the Tenant Improvements, Tenant shall provide Landlord
with a detailed cost breakdown, by trade, of the final costs to be incurred in
connection with the design and construction of the Tenant Improvements (the
"Final Costs") and within three (3) business days of receipt, Landlord shall
either approve the Final Costs or make reasonable modifications to the
calculation of such Final Costs. Prior to the commencement of construction of
the Tenant Improvements, Tenant shall supply Landlord with cash in an amount
(the "Over-Allowance Amount") equal to the difference between the Final Costs
and the Tenant Improvement Allowance. The Over-Allowance Amount shall be
disbursed by Landlord prior to the disbursement of any of the then remaining
portion of the Tenant Improvement Allowance pursuant to the same procedure as
the disbursement of the Tenant Improvement Allowance. In the event that after
the Final Costs have been delivered by Landlord to Tenant, the costs relating to
the design and construction of the Tenant Improvements shall change, any
additional costs in excess of the Final Costs shall be paid by Tenant to
Landlord immediately as an addition to the Over-Allowance Amount.

                     4.2.2 Tenant's Agents.

                     4.2.2.1 Landlord's General Conditions for Tenant's Agents
and Tenant Improvement Work. Tenant, Contractor, and all subcontractors,
laborers, materialmen, and suppliers used by Tenant (such subcontractors,
laborers, materialmen, and suppliers, and the Contractor to be known
collectively as "Tenant's Agents"), in the construction of the Tenant
Improvements, shall comply with the following: (i) the Tenant Improvements shall
be constructed in strict accordance with the Approved Working Drawings; (ii)
Tenant and Tenant's Agents shall not, in any way, interfere with, obstruct, or
delay, the work of Landlord's base building contractor and subcontractors with
respect to the base building or any other work in the Property; (iii) Tenant's
Agents shall submit schedules of all work relating to the Tenant's Improvements
to Contractor and Contractor shall, within five (5) business days of receipt
thereof, inform Tenant's Agents of any changes which are necessary thereto, and
Tenant's Agents shall adhere to such corrected schedule; and (iv) Tenant shall
abide by all rules made by Landlord or Landlord's Property manager with respect
to any matter in connection with this Tenant Work Letter, including, without
limitation, the construction of the Tenant Improvements.

                     4.2.2.2 Indemnity. Tenant's indemnity of Landlord as set
forth in Section 5.01 of this Lease shall also apply with respect to any and all
costs, losses, damages, injuries and liabilities related in any way to any act
or omission of Tenant or Tenant's Agents, or anyone directly or indirectly
employed by any of them, or in connection with Tenant's non-payment of any
amount arising out of the Tenant Improvements and/or Tenant's disapproval of all
or any portion of any request for payment. Such indemnity by Tenant, as set
forth in Section 5.01 of this Lease, shall also apply with respect to any and
all costs, losses, damages, injuries and liabilities related in any way to
Landlord's performance of any ministerial acts reasonably necessary (i) to
permit Tenant to complete the Tenant Improvements, and (ii) to enable Tenant to
obtain any building permit or certificate of occupancy for the Property.

                     4.2.2.3 Requirements of Tenant's Agents. Each of Tenant's
Agents shall guarantee to Tenant and for the benefit of Landlord that the
portion of the Tenant Improvements for which it is responsible shall be free
from any defects in workmanship and materials for a period of not less than one

performance, and not of collection. Upon any breach or default by Tenant under
the Lease, Landlord may proceed immediately against Tenant and/or any Guarantor
to enforce any of Landlord's rights or remedies against Tenant or any Guarantor

limitations as to Tenant shall operate to toll the statute of limitations as to

           5. SEPARATE AND DISTINCT OBLIGATIONS. Each Guarantor acknowledges and
agrees that such Guarantor's obligations to Landlord under this Guaranty are
separate and distinct from tenant's obligations to Landlord under eh Lease. The

laws, as now constituted or hereafter amended or replace, or any other

or liquidation of any of its affairs and the continuance of any such decree or
order unstayed and in effect for a period of sixty (60) consecutive days. The
liability of Guarantors under this Guaranty is not and shall not be affected or
impaired by any payment made to Landlord under or related to the Lease for which
Landlord is required to reimburse Tenant pursuant to any court order or in
settlement of any dispute, controversy or litigation in any bankruptcy,
reorganization, arrangement, moratorium or other federal or state debtor relief
proceeding. If , during any such proceeding, the Lease is assumed by Tenant or
any trustee, or thereafter assigned by Tenant or any trustee to a trustee or any
such third party's obligations under the Lease.

           6. SUBORDINATION. All existing and future advances by Guarantor to
Tenant, and all existing and future debts of Tenant to any Guarantor, shall be
subordinated to all obligations owed to Landlord under the Lease and this
Guaranty.

personal representatives, successors and assign.

or the rents, issues or profits therefrom, are subject to any deed of trust,
mortgage or assignment for security, any Guarantor's acquisition of Landlord's
interest in the Property or Lease shall not affect any of Guarantor's
obligations under this Guaranty. In such event, this Guaranty shall nevertheless
continue in full force and effect for the benefit of any mortgagee, beneficiary,
trustee or assignee or any purchaser at any sale by judicial foreclosure or
under any private power of sale, and their successors and assigns. Any married
Guarantor expressly agrees that Landlord has recourse against any Guarantor's
separate property for all of such Guarantor's obligations hereunder.

informed of the financial condition of Tenant, and of all other circumstances
bearing upon the risk of Tenant's default, which reasonable inquiry would reveal
and agree that Landlord shall have no duty to advise Guarantors of information
known to it regarding such condition or any such circumstance.

           10. LANDLORD'S RELIANCE. Landlord shall not be required to inquire
into the powers of Tenant or the officers, employees, partners or agents acting
or purporting to act on its behalf, and any indebtedness made or created in
reliance upon the professed exercise of such powers shall be guaranteed under
this Guaranty.
