Trustee:  Bank One, National Association

Financial Guaranty Insurance Company  ("Financial  Guaranty"),  a New York stock
insurance  company,  in  consideration  of the right of  Financial  Guaranty  to
receive monthly premiums pursuant to the Pooling and Servicing Agreement and the
Insurance Agreement referred to therein, and subject to the terms of this Surety
Bond, hereby  unconditionally and irrevocably agrees to pay each Insured Amount,
to the extent set forth in the  Pooling  and  Servicing  Agreement  (as  defined
below), to the Trustee named above or its successor,  as trustee for the Holders
of the Class A-II Certificates, except as otherwise provided herein with respect
to preference  amounts.  Capitalized terms used and not otherwise defined herein
shall have the  meanings  assigned to such terms in the  Pooling  and  Servicing
Agreement as in effect and executed on the date hereof.

The  term  "Deficiency  Amount"  shall  mean  with  respect  to the  Class  A-II
Certificates as of any Distribution Date, (i) any shortfall in amounts available
in the  Certificate  Account on that  Distribution  Date to pay interest for the
related  Interest  Accrual Period on the  Certificate  Principal  Balance of the
Class A-II  Certificates at the  then-applicable  Pass-Through  Rate, net of any
interest shortfalls relating to the Relief Act, any Group II Prepayment Interest
Shortfalls  and  any  Basis  Risk   Shortfalls   allocated  to  the  Class  A-II
Certificates, (ii) the principal portion of any Realized Losses allocated to the

The term "Insured  Amount" for any  Distribution  Date means (1) any  Deficiency
Amount  for such  Distribution  Date and (2) any  Preference  Amount  to be paid
pursuant to the terms of this Surety Bond on the Distribution Date.

<PAGE>

The term "Scheduled  Final  Distribution  Date" for the Class A-II  Certificates
means the Distribution Date occurring in September, 2031.

Financial  Guaranty will pay a Deficiency  Amount with respect to the Class A-II
Certificates  by 12:00 noon (New York City Time) in immediately  available funds
to the Trustee on the later of (i) the Business Day  following  the Business Day
on which Financial  Guaranty shall have received Notice that a Deficiency Amount
is due in respect of the Class A-II  Certificates and (ii) the Distribution Date
on which the related  Deficiency  Amount is  distributable to the Holders of the
Class A-II  Certificates  pursuant to the Pooling and Servicing  Agreement,  for
disbursement to the Holders of the Class A-II Certificates in the same manner as
other  payments with respect to the Class A-II  Certificates  are required to be
made. Any Notice  received by Financial  Guaranty after 12:00 noon New York City
time on a given  Business  Day or on any day that is not a Business Day shall be
deemed  to have been  received  by  Financial  Guaranty  on the next  succeeding
Business Day.

Upon  payment  of  a  Deficiency  Amount,  Financial  Guaranty  shall  be  fully
subrogated  to the  rights of the  Holders  of the Class  A-II  Certificates  to
receive the amount so paid. Financial Guaranty's obligations with respect to the
Class A-II  Certificates  hereunder with respect to each Distribution Date shall
be discharged to the extent funds  consisting of the related  Deficiency  Amount
are  received  by the  Trustee  on  behalf  of the  Holders  of the  Class  A-II
Certificates  for  payment to such  Holders,  as  provided  in the  Pooling  and
Servicing  Agreement and herein,  whether or not such funds are properly applied
by the Trustee.

If any  portion  or all of  any  amount  that  is  insured  hereunder  that  was
previously distributed to a holder of Class A-II Certificates is recoverable and
recovered  from such Holder as a voidable  preference by a trustee in bankruptcy
pursuant to the U.S. Bankruptcy Code, pursuant to a final  non-appealable  order
of a court exercising proper jurisdiction in an insolvency  proceeding (a "Final
Order") (such recovered amount, a "Preference Amount"),  Financial Guaranty will
pay on the guarantee described in the first paragraph hereof, an amount equal to
each such Preference  Amount by 12:00 noon on the next  Distribution  Date after
the Business Day following receipt by Financial Guaranty of (x) a certified copy
of the Final  Order,  (y) an  assignment,  in form  reasonably  satisfactory  to
Financial Guaranty,  irrevocably  assigning to Financial Guaranty all rights and
claims of the Trustee and/or such Holder of the Class A-II Certificates relating
to or arising under such Preference Amount and appointing  Financial Guaranty as
the agent of the  Trustee  and/or  such  Holder in  respect  of such  Preference
Amount, and (z) a Notice appropriately  completed and executed by the Trustee or
such  Holder,  as the case may be. Such payment  shall be made to the  receiver,
conservator,  debtor-in-possession  or trustee in bankruptcy  named in the Final
Order  and not to the  Trustee  or Holder of Class  A-II  Certificates  directly
(unless  the  Holder  has   previously   paid  such  amount  to  such  receiver,
conservator,  debtor-in-possession or trustee named in such Final Order in which
case payment  shall be made to the Trustee for  distribution  to the Holder upon
proof  of  such  payment   reasonably   satisfactory  to  Financial   Guaranty).
Notwithstanding  the  foregoing,  in no event  shall  Financial  Guaranty be (i)
required to make any payment under this Surety Bond in respect of any Preference
Amount to the extent such Preference  Amount is comprised of amounts  previously
paid by Financial Guaranty  hereunder,  or (ii) obligated to make any payment in
respect of any  Preference  Amount,  which  payment  represents a payment of the
principal  amount of any Class A-II  Certificates,  prior to the time  Financial
Guaranty otherwise would have been required to make a payment in respect of such
principal,  in which  case  Financial  Guaranty  shall  pay the  balance  of the
Preference Amount when such amount otherwise would have been required.

<PAGE>

Any of the  documents  required  under  clauses (x) through (z) of the preceding
paragraph that are received by Financial Guaranty after 12:00 noon New York City
time on a given  Business  Day or on any day that is not a Business Day shall be
deemed  to have been  received  by  Financial  Guaranty  on the next  succeeding
Business  Day. All payments made by Financial  Guaranty  hereunder in respect of
Preference Amounts will be made with Financial Guaranty's own funds.

This Surety Bond is non-cancelable for any reason,  including  nonpayment of any
premium.  The  premium on this  Surety  Bond is not  refundable  for any reason,
including the payment of any Class A-II  Certificates  prior to their respective
maturities.  This Surety Bond shall expire and  terminate  without any action on
the part of Financial Guaranty or any other Person on the date that is the later
of (i) the date  that is one year and one day  following  the date on which  the
Class A-II Certificates  shall have been paid in full and (ii) if any insolvency
proceeding  with respect to which the Depositor is the debtor has been commenced
on or prior to the date  specified  in clause (i) above,  the 30th day after the
entry of a final,  non-appealable  order in  resolution  or  settlement  of such
proceeding.

A monthly premium shall be due and payable in arrears as provided in the Pooling
and Servicing Agreement.

This Surety Bond is subject to and shall be governed by the laws of the State of
New York.  The proper  venue for any action or  proceeding  on this  Surety Bond
shall be the County of New York,  State of New York.  The insurance  provided by
this  Surety  Bond is not  covered by the New York  Property/Casualty  Insurance
Security Fund (New York Insurance Code, Article 76).

"Notice"  means a written notice in the form of Exhibit A to this Surety Bond by
registered or certified mail or telephonic or telegraphic  notice,  subsequently
confirmed by written notice delivered via telecopy,  telex or hand delivery from
the Trustee to Financial Guaranty  specifying the information set forth therein.
"Holder" means, as to a particular  Class A-II  Certificate,  the person,  other
than the Master Servicer, any subservicer retained by the Master Servicer or the

<PAGE>

Depositor who, on the applicable  Distribution Date, is entitled under the terms
of such Class A-II Certificate to a distribution thereon. "Pooling and Servicing
Agreement" means the Pooling and Servicing  Agreement relating to the Class A-II
Certificates  by  and  among  Residential  Asset  Securities   Corporation,   as
Depositor,  Residential Funding Corporation,  as Master Servicer,  and Bank One,
National Association, as Trustee, dated as of September 1, 2000.

In the event that payments  under any Class A-II  Certificate  are  accelerated,
nothing herein contained shall obligate  Financial  Guaranty to make any payment
of principal or interest on such Class A-II Certificate on an accelerated basis,
unless such acceleration of payment by Financial  Guaranty is at the sole option
of Financial  Guaranty;  it being understood that a payment shortfall in respect
of the redemption of any Class A-II Certificates by reason of the termination of
the Trust Fund  pursuant to Article IX of the Pooling  and  Servicing  Agreement
does not constitute acceleration for the purposes hereof.

IN WITNESS WHEREOF, Financial Guaranty has caused this Surety Bond to be affixed
with its  corporate  seal and to be signed  by its duly  authorized  officer  in
facsimile to become  effective and binding upon Financial  Guaranty by virtue of
the countersignature of its duly authorized representative.

        on the Class A-II  Certificates  (net of any shortfalls  relating to the
        Relief Act and any Group I Prepayment Interest  shortfalls  allocated to
        the Class A-I  Certificates  and any Basis  Risk  Shortfalls)  and (B) $
        ___________  in respect of the  principal  portion  of  Realized  Losses

        jurisdiction  imposing  a stay  pursuant  to  Section  362 of the United

        Please be advised that, accordingly,  a Deficiency Amount exists for the

Any person who  knowingly  and with intent to defraud any  insurance  company or

Agreement as in effect and executed on the date hereof.

The  term  "Deficiency  Amount"  shall  mean  with  respect  to  the  Class  A-I

received by the  Trustee on behalf of the Holders of the Class A-I  Certificates
for payment to such Holders,  as provided in the Pooling and Servicing Agreement
and herein, whether or not such funds are properly applied by the Trustee.

If any  portion  or all of  any  amount  that  is  insured  hereunder  that  was
previously  distributed to a holder of Class A-I Certificates is recoverable and
recovered  from such Holder as a voidable  preference by a trustee in bankruptcy
pursuant to the U.S. Bankruptcy Code, pursuant to a final  non-appealable  order
of a court exercising proper jurisdiction in an insolvency  proceeding (a "Final
Order") (such recovered amount, a "Preference Amount"),  Financial Guaranty will

the agent of the  Trustee  and/or  such  Holder in  respect  of such  Preference
Amount, and (z) a Notice appropriately  completed and executed by the Trustee or
such  Holder,  as the case may be. Such payment  shall be made to the  receiver,
conservator,  debtor-in-possession  or trustee in bankruptcy  named in the Final

(unless  the  Holder  has   previously   paid  such  amount  to  such  receiver,
conservator,  debtor-in-possession or trustee named in such Final Order in which
case payment  shall be made to the Trustee for  distribution  to the Holder upon

proof  of  such  payment   reasonably   satisfactory  to  Financial   Guaranty).
Notwithstanding  the  foregoing,  in no event  shall  Financial  Guaranty be (i)
required to make any payment under this Surety Bond in respect of any Preference
Amount to the extent such Preference  Amount is comprised of amounts  previously
paid by Financial Guaranty  hereunder,  or (ii) obligated to make any payment in
respect of any  Preference  Amount,  which  payment  represents a payment of the
principal  amount  of any Class A-I  Certificates,  prior to the time  Financial
Guaranty otherwise would have been required to make a payment in respect of such
principal,  in which  case  Financial  Guaranty  shall  pay the  balance  of the
Preference Amount when such amount otherwise would have been required.

proceeding  with respect to which the Depositor is the debtor has been commenced
on or prior to the date  specified  in clause (i) above,  the 30th day after the
entry of a final,  non-appealable  order in  resolution  or  settlement  of such

covenants and conditions set forth in this Lease. Unless otherwise provided
herein, any statement of square footage set forth in this Lease, or that may
have been used in calculating rental and/or Common Area Operating Expenses, is
an approximation which Lessor and Lessee agree is reasonable and the rental and
Lessee's Share (as defined in Paragraph 1.6(b)) based thereon is not subject to
revision whether or not the actual square footage is more or less.

     2.2 CONDITION. Lessor shall deliver the Premises to Lessee clean and free
of debris on the Commencement Date and warrants to Lessee that the existing
plumbing, electrical systems, fire sprinkler system, lighting, air conditioning
and heating systems, and loading doors, if any, in the Premises, other than

Commencement Date, Lessor shall, except as otherwise provided in this Lease,
promptly after receipt of written notice from Lessee setting forth with
specificity the nature and extent of such non-compliance, rectify same at
Lessor's expense. If Lessee does not give Lessor written notice of a
non-compliance with this warranty within thirty (30) days after the

Lessee at Lessee's sole cost and expense.

     2.3 COMPLIANCE WITH COVENANTS, RESTRICTIONS AND BUILDING CODE. Lessor
warrants that any improvements (other than those constructed by Lessee or at
Lessee's direction) on or in the Premises which have been constructed or
installed by Lessor or with Lessor's consent or at Lessor's direction shall
comply with all applicable covenants or restrictions of record and applicable
building codes, regulations and ordinances in effect on the Commencement Date.
Lessor further warrants to Lessee that Lessor has no knowledge of any claim
having been made by any governmental agency that a violation or violations of
applicable building codes, regulations, or ordinances exist with regard to the
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
be made by Lessee. If the Premises do not comply with said warranties, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee given within six (6) months following the
Commencement Date and setting forth with specificity the nature and extent of
such non-compliance, take such action, at Lessor's expense, as may be

                                  Page 1 of 13
<PAGE>   2
reasonable or appropriate to rectify the non-compliance. Lessor makes no
warranty that the Permitted Use in Paragraph 1.8 is permitted for the Premises
under Applicable Laws (as defined in Paragraph 2.4).

     2.4 ACCEPTANCE OF PREMISES. Lessee hereby acknowledges: (a) that it has
been advised by the Broker(s) to satisfy itself with respect to the condition of
the Premises (including, but not limited to, the electrical and fire sprinkler
systems, security, environmental aspects, seismic and earthquake requirements,
and compliance with the Americans with Disabilities Act and applicable zoning,
municipal, county, state and federal laws, ordinances and regulations, and any
covenants or restrictions of record (collectively, "APPLICABLE LAWS") and the
present and future suitability of the Premises for Lessee's intended use; (b)
that Lessee has made such investigation as it deems necessary with reference to
such matters, is satisfied with reference thereto, and assumes all
responsibility therefore as the same relate to Lessee's occupancy of the
Premises and/or the terms of this Lease; and (c) that neither Lessor, nor any of
Lessor's agents, has made any oral or written representations or warranties with
respect to said matters other than as set forth in this Lease.

     2.5 LESSEE AS PRIOR OWNER/OCCUPANT. The warranties made by Lessor in this
Paragraph 2 shall be of no force or effect if immediately prior to the date set
forth in Paragraph 1.1 Lessee was the owner or occupant of the Premises. In such
event, Lessee shall, at Lessee's sole cost and expense, correct any
non-compliance of the Premises with said warranties.

     2.6 VEHICLE PARKING. Lessee shall be entitled to use the number of
Unreserved Parking Spaces and Reserved Parking Spaces specified in Paragraph
1.2(b) on those portions of the Common Areas designated from time to time by
Lessor for parking. Lessee shall not use more parking spaces than said number.
Said parking spaces shall be used for parking by vehicles no larger than
full-size passenger automobiles or pick-up trucks, herein called "PERMITTED SIZE
VEHICLES." Vehicles other than Permitted Size Vehicles shall be parked and
loaded or unloaded as directed by Lessor in the Rules and Regulations (as

other than those designated by Lessor for such activities.

              (b) If Lessee permits or allows any of the prohibited activities
described in this Paragraph 2.6, then Lessor shall have the right, without
notice, in addition to such other rights and remedies that it may have, to

cost shall be immediately payable upon demand by Lessor.

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

amend and enforce reasonable Rules and Regulations with respect thereto in
accordance with Paragraph 40. Lessee agrees to abide by and conform to all such
Rules and Regulations, and to cause its employees, suppliers, shippers,

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

              (c) The inclusion of the improvements, facilities and services set
forth in Subparagraph 4.2(a) shall not be deemed to impose an obligation upon
Lessor to either have said improvements or facilities or to provide those

the same or some of them.

              (d) Lessee's Share of Common Area Operating Expenses shall be
payable by Lessee within ten (10) days after a reasonably detailed statement of
actual expenses is presented to Lessee by Lessor. At Lessor's option, however,
an amount may be estimated by Lessor from time to time of Lessee's Share of
annual Common Area Operating Expenses and the same shall be payable monthly or
quarterly, as Lessor shall designate, during each 12-month period of the Lease
term, on the same day as the Base Rent is due hereunder. Lessor shall deliver to
Lessee within sixty (60) days after the expiration of each calendar year a
reasonably detailed statement showing Lessee's Share of the actual Common Area
Operating Expenses incurred during the preceding year. If Lessee's payments
under this Paragraph 4.2(d) during said preceding year exceed Lessee's Share as
indicated on said statement, Lessee shall be credited the amount of such
overpayment against Lessee's Share of Common Area Operating Expenses next
becoming due. If Lessee's payments under this Paragraph 4.2(d) during said
preceding year were less than Lessee's Share as indicated on said statement,
Lessee shall pay to Lessor the amount of the deficiency within ten (10) days
after delivery by Lessor to Lessee of said statement.

5. SECURITY DEPOSIT. Lessee shall deposit with Lessor upon Lessee's execution
hereof the Security Deposit set forth in Paragraph 1.7 as security for Lessee's
faithful performance of Lessee's obligations under this Lease. If Lessee fails
to pay Base Rent or other rent or charges due hereunder, or otherwise Defaults
under this Lease (as defined in Paragraph 13.1), Lessor may use, apply or retain
all or any portion of said Security Deposit for the payment of any amount due
Lessor or to reimburse or compensate Lessor for any liability, cost, expense,
loss or damage (including attorneys' fees) which Lessor may suffer or incur by
reason thereof. If Lessor uses or applies all or any portion of said Security
Deposit, Lessee shall within ten (10) days after written request therefore
deposit monies with Lessor sufficient to restore said Security Deposit to the
full amount required by this Lease. Any time the Base Rent increases during the
term of this Lease, Lessee shall, upon written request from Lessor, deposit
additional monies with Lessor as an addition to the Security Deposit so that the
total amount of the Security Deposit shall at all times bear the same proportion
to the then current Base Rent as the initial Security Deposit bears to the
initial Base Rent set forth in Paragraph 1.5. Lessor shall not be required to
keep all or any part of the Security Deposit separate from its general accounts.
Lessor shall, at the expiration or earlier termination of the term hereof and
after Lessee has vacated the Premises, return to Lessee (or, at Lessor's option,
to the last assignee, if any, of Lessee's interest herein), that portion of the
Security Deposit not used or applied by Lessor. Unless otherwise expressly
agreed in writing by Lessor, no part of the Security Deposit shall be considered
to be held in trust, to bear interest or other increment for its use, or to be
prepayment for any monies to be paid by Lessee under this Lease.

6.   USE.

     6.1 PERMITTED USE.

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

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

     6.2 HAZARDOUS SUBSTANCES.

              (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS
SUBSTANCE" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of
existence, use, manufacture, disposal, transportation, spill, release or effect,
either by itself or in combination with other materials expected to be on the
Premises, is either: (i) potentially injurious to the public health, safety or
welfare, the environment, or the Premises; (ii) regulated or monitored by any
governmental authority; or (iii) a basis for potential liability of Lessor to
any governmental agency or third party under any applicable statute or common
law theory. Hazardous Substance shall include, but not be limited to,
hydrocarbons, petroleum, gasoline, crude oil or any products or by-products
thereof. Lessee shall not engage in any activity in or about the Premises which
constitutes a Reportable Use (as hereinafter defined) of Hazardous Substances
without the express prior written consent of Lessor and compliance in a timely
manner (at Lessee's sole cost and expense) with all Applicable Requirements (as
defined in Paragraph 6.3). "REPORTABLE USE" shall mean (i) the installation or
use of any above or below ground storage tank; (ii) the generation, possession,
storage, use, transportation, or disposal of a Hazardous Substance that requires
a permit from, or with respect to which a report, notice, registration or
business plan is required to be filed with, any governmental authority; and
(iii) the presence in, on or about the Premises of a Hazardous Substance with
respect to which any Applicable Laws require that a notice be given to persons
entering or occupying the Premises or neighboring properties. Notwithstanding
the foregoing, Lessee may, without Lessor's prior consent, but upon notice to
Lessor and in compliance with all Applicable Requirements, use any ordinary and
customary materials reasonably required to be used by Lessee in the normal
course of the Permitted Use, so long as such use is not a Reportable Use and
does not expose the Premises or neighboring properties to any meaningful risk of
contamination or damage or expose Lessor to any liability therefor. In addition,
Lessor may (but without any obligation to do so) condition its consent to any
Reportable Use of any Hazardous Substance by Lessee upon Lessee's giving Lessor
such additional assurances as Lessor, in its reasonable discretion, deems
necessary to protect itself, the public, the Premises and the environment
against damage, contamination or injury and/or liability therefor, including,
but not limited to, the installation (and, at Lessor's option, removal on or
before Lease expiration or earlier termination) of reasonably necessary
protective modifications to the Premises (such as concrete encasements) and/or
the deposit of an additional Security Deposit under Paragraph 5 hereof.

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

              (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and
hold Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all damages, liabilities, judgments,
costs, claims, liens, expenses, penalties, loss of permits and attorneys' and
consultants' fees arising out of or involving any Hazardous Substance brought
onto the Premises by or for Lessee or by anyone under Lessee's control. Lessee's
obligations under this Paragraph 6.2(c) shall include, but not be limited to,
the effects of any contamination or injury to person, property or the
environment created or suffered by Lessee, and the cost of investigation
(including consultants' and attorneys' fees and testing), removal, remediation,
restoration and/or abatement thereof, or of any contamination therein involved,
and shall survive the expiration or earlier termination of this Lease. No
termination, cancellation or release agreement entered into by Lessor and
Lessee shall release Lessee from its obligations under this Lease with respect
to Hazardous Substances, unless specifically so agreed by Lessor in writing at
the time of such agreement.
*
     6.3 LESSEE'S COMPLIANCE WITH REQUIREMENTS. Lessee shall, at Lessee's sole
cost and expense, fully, diligently and in a timely manner, comply with all
"APPLICABLE REQUIREMENTS," which term is used in this Lease to mean all laws,
rules, regulations, ordinances, directives, covenants, easements and

*See Addendum 6.2(d)
                                  Page 3 of 13

<PAGE>   4
restrictions of record, permits, the requirements of any applicable fire
insurance underwriter or rating bureau, and the recommendations of Lessor's
engineers and/or consultants, relating in any manner to the Premises (including,
but not limited to, matters pertaining to (i) industrial hygiene; (ii)
environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions; and (iii) the use, generation, manufacture, production,
installation, maintenance, removal, transportation, storage, spill, or release
of any Hazardous Substance), now in effect or which may hereafter come into
effect. Lessee shall, within five (5) days after receipt of Lessor's written
request, provide Lessor with copies of all documents and information, including,
but not limited to, permits, registrations, manifests, applications, reports and
certificates, evidencing Lessee's compliance with any Applicable Requirements
specified by Lessor, and shall immediately upon receipt, notify Lessor in
writing (with copies of any documents involved) of any threatened or actual
claim, notice, citation, warning, complaint or report pertaining to or involving
failure by Lessee or the Premises to comply with any Applicable Requirements.

     6.4 INSPECTION; COMPLIANCE WITH LAW. Lessor, Lessor's agents, employees,
contractors and designated representatives, and the holders of any mortgages,
deeds of trust or ground leases on the Premises ("LENDERS") shall have the right
to enter the Premises at any time in the case of an emergency, and otherwise at
reasonable times, for the purpose of inspecting the condition of the Premises
and for verifying compliance 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.

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

     7.1  LESSEE'S OBLIGATIONS.

          (a) Subject to the provisions of Paragraphs 2.2 (Condition), 2.3
(Compliance with Covenants, Restrictions and Building Code), 7.2 (Lessor's
Obligations), 9 (Damage or Destruction), and 14 (Condemnation), Lessee shall, at
Lessee's sole cost and expense and at all times, keep the Premises and every
part thereof in good order, condition and repair (whether or not such portion of
the Premises requiring repair, or the means of repairing the same, are
reasonably or readily accessible to Lessee, and whether or not the need for such
repairs occurs as a result of Lessee's use, any prior use, the elements or the
age of such portion of the Premises), including, without limiting the generality
of the foregoing, all equipment or facilities specifically serving the Premises,
such as plumbing, heating, air conditioning, ventilating, electrical, lighting
facilities, boilers, fired or unfired pressure vessels, fire hose connections if
within the Premises, fixtures, interior walls, interior surfaces of exterior
walls, ceilings, floors, windows, doors, plate glass, and skylights, but
excluding any items which are the responsibility of Lessor pursuant to Paragraph
7.2 below. Lessee, in keeping the Premises in good order, condition and repair,
shall exercise and perform good maintenance practices. Lessee's obligations
shall include restorations, replacements or renewals when necessary to keep the
Premises and all improvements thereon or a part thereof in good order, condition
and state of repair.

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

              (c) If Lessee fails to perform Lessee's obligations under this
Paragraph 7.1, Lessor may enter upon the Premises after ten (10) days' prior
written notice to Lessee (except in the case of an emergency, in which case no
notice shall be required), perform such obligations on Lessee's behalf, and put
the Premises in good order, condition and repair, in accordance with Paragraph
13.2 below.

     7.2  LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 2.2
(Condition), 2.3 (Compliance with Covenants, Restrictions and Building Code),
4.2 (Common Area Operating Expenses), 6 (Use), 7.1 (Lessee's Obligations), 9
(Damage or Destruction) and 14 (Condemnation), Lessor, subject to reimbursement
pursuant to Paragraph 4.2, shall keep in good order, condition and repair the
foundations, exterior walls, structural condition of interior bearing walls,
exterior roof, fire sprinkler and/or standpipe and hose (if located in the
Common Areas) or other automatic fire extinguishing system including fire alarm
and/or smoke detection systems and equipment, fire hydrants, parking lots,
walkways, parkways, driveways, landscaping, fences, signs and utility systems
serving the Common Areas and all parts thereof, as well as providing the
services for which there is a Common Area Operating Expense pursuant to
Paragraph 4.2. Lessor shall not be obligated to paint the exterior or interior
surfaces of exterior walls nor shall Lessor be obligated to maintain, repair or
replace windows, doors or plate glass of the Premises. Lessee expressly waives
the benefit of any statute now or hereafter in effect which would otherwise
afford Lessee the right to make repairs at Lessor's expense or to terminate this
Lease because of Lessor's failure to keep the Building, Industrial Center or
Common Areas in good order, condition and repair.*

     7.3  UTILITY INSTALLATIONS, TRADE FIXTURES, ALTERATIONS.

          (a) DEFINITIONS; CONSENT REQUIRED. The term "UTILITY
INSTALLATIONS" is used in this Lease to refer to all air lines, power panels,
electrical distribution, security, fire protection systems, communications
systems, lighting fixtures, heating, ventilating and air conditioning equipment,
plumbing, and fencing in, on or about the Premises. The term "TRADE FIXTURES"
shall mean Lessee's machinery and equipment which can be removed without doing
material damage to the Premises. The term "ALTERATIONS" shall mean any
modification of the improvements on the Premises which are provided by Lessor
under the terms of this Lease, other than Utility Installations or Trade
Fixtures. "LESSEE-OWNED ALTERATIONS AND/OR UTILITY INSTALLATIONS" are defined as
Alterations and/or Utility Installations made by Lessee that are not yet owned
by Lessor pursuant to Paragraph 7.4(a). Lessee shall not make nor cause to be
made any Alterations or Utility Installations in, on, under or about the
Premises without Lessor's prior written consent. Lessee may, however, make
non-structural Utility Installations to the interior of the Premises (excluding
the roof) without Lessor's consent but upon notice to Lessor, so long as they
are not visible from the outside of the Premises, do not involve puncturing,
relocating or removing the roof or any existing walls, or changing or
interfering with the fire sprinkler or fire detection systems and the cumulative
cost thereof during the term of this Lease as extended does not exceed
$10,000.00.

              (b) CONSENT. Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with detailed plans. All consents given by
Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific consent,
shall be deemed conditioned upon: (i) Lessee's acquiring all applicable permits
required by governmental authorities; (ii) the furnishing of copies of such
permits together with a copy of the plans and specifications for the Alteration
or Utility Installation to Lessor prior to commencement of the work thereon; and
(iii) the compliance by Lessee with all conditions of said permits in a prompt
and expeditious manner. Any Alterations or Utility Installations by Lessee
during the term of this Lease shall be done in a good and workmanlike manner,
with good and sufficient materials, and be in compliance with all Applicable
Requirements. Lessee shall promptly upon completion thereof furnish Lessor with
as-built plans and specifications therefor. Lessor may (but without obligation
to do so) condition its consent to any requested Alteration or Utility
Installation that costs $2,500.00 or more upon Lessee's providing Lessor with a
lien and completion bond in an amount equal to one and one-half times the
estimated cost of such Alteration or Utility Installation.

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

     7.4  OWNERSHIP, REMOVAL, SURRENDER, AND RESTORATION.

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

          (b) REMOVAL. Unless otherwise agreed in writing, Lessor may require
that any or all Lessee-Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding that their
installation may have been consented to by Lessor. Lessor may

* See Addendum

                                  Page 4 of 13

<PAGE>   5
require the removal at any time of all or any part of any Alterations or Utility
Installations made without the required consent of Lessor.

              (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by
the end of the last day of the Lease term or any earlier termination date, clean
and free of debris and in good operating order, condition and state of repair,
ordinary wear and tear excepted. Ordinary wear and tear shall not include any
damage or deterioration that would have been prevented by good maintenance
practice or by Lessee performing all of its obligations under this Lease. Except
as otherwise agreed or specified herein, the Premises, as surrendered, shall
include the Alterations and Utility Installations. The obligation of Lessee
shall include the repair of any damage occasioned by the installation,
maintenance or removal of Lessee's Trade Fixtures, furnishings, equipment, and
Lessee-Owned Alterations and Utility Installations, as well as the removal of
any storage tank installed by or for Lessee, and the removal, replacement, or
remediation of any soil, material or ground water contaminated by Lessee, all as
may then be required by Applicable Requirements and/or good practice. Lessee's
Trade Fixtures shall remain the property of Lessee and shall be removed by
Lessee subject to its obligation to repair and restore the Premises per this
Lease.

8.   INSURANCE; INDEMNITY.

     8.1 PAYMENT OF PREMIUMS. The cost of the premiums for the insurance
policies maintained by Lessor under this Paragraph 8 shall be a Common Area
Operating Expense pursuant to Paragraph 4.2 hereof. Premiums for policy periods
commencing prior to, or extending beyond, the term of this Lease shall be
prorated to coincide with the corresponding Commencement Date or Expiration
Date.

     8.2 LIABILITY INSURANCE.

              (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force
during the term of this Lease a Commercial General Liability policy of insurance
protecting Lessee, Lessor and any Lender(s) whose names have been provided to
Lessee in writing (as additional insureds) against claims for bodily injury,
personal injury and property damage based upon, involving or arising out of the
ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto. Such insurance shall be on an occurrence basis providing
single limit coverage in an amount not less than $1,000,000 per occurrence with
an "Additional Insured-Managers or Lessors of Premises" endorsement and contain
the "Amendment of the Pollution Exclusion" endorsement for damage caused by
heat, smoke or fumes from a hostile fire. The policy shall not contain any
intra-insured exclusions as between insured persons or organizations, but shall
include coverage for liability assumed under this Lease as an "INSURED CONTRACT"
for the performance of Lessee's indemnity obligations under this Lease. The
limits of said insurance required by this Lease or as carried by Lessee shall
not, however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder. All insurance to be carried by Lessee shall be primary to and not
contributory with any similar insurance carried by Lessor, whose insurance shall
be considered excess insurance only.

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

     8.3 PROPERTY INSURANCE - BUILDING, IMPROVEMENTS AND RENTAL VALUE.

              (a) BUILDING AND IMPROVEMENTS. Lessor shall obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and to any Lender(s), insuring against loss or
damage to the Premises. Such insurance shall be for full replacement cost, as
the same shall exist from time to time, or the amount required by any Lender(s),
but in no event more than the commercially reasonable and available insurable
value thereof if, by reason of the unique nature or age of the improvements
involved, such latter amount is less than full replacement cost. Lessee-Owned
Alterations and Utility Installations, Trade Fixtures and Lessee's personal
property shall be insured by Lessee pursuant to Paragraph 8.4. If the coverage
is available and commercially appropriate, Lessor's policy or policies shall
insure against all risks of direct physical loss or damage (except the perils of
flood and/or earthquake unless required by a Lender), including coverage for any
additional costs resulting from debris removal and reasonable amounts of
coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Building required
to be demolished or removed by reason of the enforcement of any building,
zoning, safety or land use laws as the result of a covered loss, but not
including plate glass insurance. Said policy or policies shall also contain an
agreed valuation provision in lieu of any co-insurance clause, waiver of
subrogation, and inflation guard protection causing an increase in the annual
property insurance coverage amount by a factor of not less than the adjusted
U.S. Department of Labor Consumer Price Index for All Urban Consumers for the
city nearest to where the Premises are located.

              (b) RENTAL VALUE. Lessor shall also obtain and keep in force
during the term of this Lease a policy or policies in the name of Lessor, with
loss payable to Lessor and any Lender(s), insuring the loss of the full rental
and other charges payable by all lessees of the Building to Lessor for one year
(including all Real Property Taxes, insurance costs, all Common Area Operating
Expenses and any scheduled rental increases). Said insurance may provide that in
the event the Lease is terminated by reason of an insured loss, the period of
indemnity for such coverage shall be extended beyond the date of the completion
of repairs or replacement of the Premises, to provide for one full year's loss
of rental revenues from the date of any such loss. Said insurance shall contain
an agreed valuation provision in lieu of any co-insurance clause, and the amount
of coverage shall be adjusted annually to reflect the projected rental income,
Real Property Taxes, insurance premium costs and other expenses, if any,
otherwise payable, for the next 12-month period. Common Area Operating Expenses
shall include any deductible amount in the event of such loss.

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

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

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

     8.5 INSURANCE POLICIES. Insurance required hereunder shall be in companies
duly licensed to transact business in the state where the Premises are located,
and maintaining during the policy term a "General Policyholders Rating" of at
least B+, V, or such other rating as may be required by a Lender, as set forth
in the most current issue of "Best's Insurance Guide." Lessee shall not do or
permit to be done anything which shall invalidate the insurance policies
referred to in this Paragraph 8. Lessee shall cause to be delivered to Lessor,
within seven (7) days after the earlier of the Early Possession Date or the
Commencement Date, certified copies of, or certificates evidencing the existence
and amounts of, the insurance required under Paragraph 8.2(a) and 8.4. No such
policy shall be cancelable or subject to modification except after thirty (30)
days' prior written notice to Lessor. Lessee shall, at least thirty (30) days
prior to the expiration of such policies, furnish Lessor with evidence of
renewals or "insurance binders" evidencing renewal thereof, or Lessor may order
such insurance and charge the cost thereof to Lessee, which amount shall be
payable by Lessee to Lessor upon demand. See Addendum.

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

     8.7 INDEMNITY. Except for Lessor's negligence and/or breach of express
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, loss of permits, attorneys' and consultants'
fees, expenses and/or liabilities arising out of, involving, or in connection
with, the occupancy of the Premises by Lessee, the conduct of Lessee's business,
any act, omission or neglect of Lessee, its agents, contractors, employees or
invitees, and out of any Default or Breach by Lessee in the performance in a
timely manner of any obligation on Lessee's part to be performed under this
Lease. The foregoing shall include, but not be limited to, the defense or
pursuit of any claim or any action or proceeding involved therein, and whether
or not (in the case of claims made against Lessor) litigated and/or reduced to
judgment. In case any action or proceeding be brought against Lessor by reason
of any of the foregoing matters, Lessee, upon notice from Lessor, shall defend
the same at Lessee's expense by counsel reasonably satisfactory to Lessor and
Lessor shall cooperate with Lessee in such defense. Lessor need not have first
paid any such claim in order to be so indemnified.

     8.8 EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinklers, wires,
appliances, plumbing, air conditioning or lighting fixtures, or from any other
cause, whether said injury or damage results from conditions arising upon the
<PAGE>   6
Premises or upon other portions of the Building of which the Premises are a
part, from other sources or places, and regardless of whether the cause of such
damage or injury or the means of repairing the same is accessible or not. Lessor
shall not be liable for any damages arising from any act or neglect of any other
lessee of Lessor nor from the failure by Lessor to enforce the provisions of any
other lease in the Industrial Center. Notwithstanding Lessor's negligence or
breach of this Lease, Lessor shall under no circumstances be liable for injury
to Lessee's business or for any loss of income or profit therefrom.

  9.   DAMAGE OR DESTRUCTION.

     9.1 DEFINITIONS.

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

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

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

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

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

     9.2 PREMISES PARTIAL DAMAGE -- INSURED LOSS. If Premises Partial Damage
that is an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair
such damage (but not Lessee's Trade Fixtures or Lessee-Owned Alterations and
Utility Installations) as soon as reasonably possible and this Lease shall
continue in full force and effect. In the event, however, that there is a
shortage of insurance proceeds and such shortage is due to the fact that, by
reason of the unique nature of the improvements in the Premises, full
replacement cost insurance coverage was not commercially reasonable and
available, Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,
within ten (10) days following receipt of written notice of such shortage and
request therefor. If Lessor receives said funds or adequate assurance thereof
within said ten (10) day period, Lessor shall complete them as soon as
reasonably possible and this Lease shall remain in full force and effect. If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect. If Lessor does not receive such funds or assurance within such
ten (10) day period, and if Lessor does not so elect to restore and repair, then
this Lease shall terminate sixty (60) days following the occurrence of the
damage or destruction. Unless otherwise agreed, Lessee shall in no event have
any right to reimbursement from Lessor for any funds contributed by Lessee to
repair any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to Paragraph 9.3 rather than Paragraph 9.2,
notwithstanding that there may be some insurance coverage, but the net proceeds
of any such insurance shall be made available for the repairs if made by either
Party. See Addendum.

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

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

     9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6) months
of the term of this Lease there is damage for which the cost to repair exceeds
one month's Base Rent, whether or not an Insured Loss, Lessor may, at Lessor's
option, terminate this Lease effective sixty (60) days following the date of
occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by (a) exercising such option, and (b) providing Lessor with any shortage
in insurance proceeds (or adequate assurance thereof) needed to make the repairs
on or before the earlier of (i) the date which is ten (10) days after Lessee's
receipt of Lessor's written notice purporting to terminate this Lease, or (ii)
the day prior to the date upon which such option expires. If Lessee duly
exercises such option during such period and provides Lessor with funds (or
adequate assurance thereof) to cover any shortage in insurance proceeds, Lessor
shall, at Lessor's expense, repair such damage as soon as reasonably possible
and this Lease shall continue in full force and effect. If Lessee fails to
exercise such option and provide such funds or assurance during such period,
then this Lease shall terminate as of the date set forth in the first sentence
of this Paragraph 9.5.

     9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES.

              (a) In the event of (i) Premises Partial Damage or (ii) Hazardous
Substance Condition for which Lessee is not legally responsible, the Base Rent,
Common Area Operating Expenses and other charges, if any, payable by Lessee
hereunder for the period during which such damage or condition, its repair,
remediation or restoration continues, shall be abated in proportion to the
degree to which Lessee's use of the Premises is impaired, but not in excess of
proceeds from insurance required to be carried under Paragraph 8.3(b). Except
for abatement of Base Rent, Common Area Operating Expenses and other charges, if
any, as aforesaid, all other obligations of Lessee hereunder shall be performed
by Lessee, and Lessee shall have no claim against Lessor for any damage suffered
by reason of any such damage, destruction, repair, remediation or restoration.

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

     9.7 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable
Requirements and this Lease shall continue in full force and effect, but subject
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

                                  Page 6 of 13
<PAGE>   7
intention to terminate this Lease, Lessee shall have the right within ten (10)
days after the receipt of such notice to give written notice to Lessor of
Lessee's commitment to pay for the excess costs of (a) investigation and
remediation of such Hazardous Substance Condition to the extent required by
Applicable Requirements, over (b) an amount equal to twelve (12) times the then
monthly Base Rent or $100,000, whichever is greater. Lessee shall provide Lessor
with the funds required of Lessee or satisfactory assurance thereof within
thirty (30) days following said commitment by Lessee. In such event this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
investigation and remediation as soon as reasonably possible after the required
funds are available. If Lessee does not give such notice and provide the
required funds or assurance thereof within the time period specified above, this
Lease shall terminate as of the date specified in Lessor's notice of
termination.

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

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

  10.  REAL PROPERTY TAXES.

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

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

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

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

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

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

  12.  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.

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

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

* See Addendum

                                  Page 7 of 13
<PAGE>   8
or to any subsequent or successive assignment or subletting by the assignee or
sublessee. However, Lessor may consent to subsequent sublettings and assignments
of the sublease or any amendments or modifications thereto without notifying
Lessee or anyone else liable under this Lease or the sublease and without
obtaining their consent, and such action shall not relieve such persons from
liability under this Lease or the sublease.

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

              (e) Each request for consent to an assignment or subletting shall
be in writing, accompanied by information relevant to Lessor's determination as
to the financial and operational responsibility and appropriateness of the
proposed assignee or sublessee, including, but not limited to, the intended use
and/or required modification of the Premises, if any, together with a
non-refundable deposit of $350.00 as reasonable consideration for Lessor's
considering and processing the request for consent. Lessee agrees to provide
Lessor with such other or additional information and/or documentation as may be
reasonably requested by Lessor.

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

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

              (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease of all or a portion
of the Premises heretofore or hereafter made by Lessee, and Lessor may collect
such rent and income and apply same toward Lessee's obligations under this
Lease; provided, however, that until a Breach (as defined in Paragraph 13.1)
shall occur in the performance of Lessee's obligations under this Lease, Lessee
may, except as otherwise provided in this Lease, receive, collect and enjoy the
rents accruing under such sublease. Lessor shall not, by reason of the foregoing
provision or any other assignment of such sublease to Lessor, nor by reason of
the collection of the rents from a sublessee, be deemed liable to the sublessee
for any failure of Lessee to perform and comply with any of Lessee's obligations
to such sublessee under such Sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor stating
that a Breach exists in the performance of Lessee's obligations under this
Lease, to pay to Lessor the rents and other charges due and to become due under
the sublease. Sublessee shall rely upon any such statement and request from
Lessor and shall pay such rents and other charges to Lessor without any
obligation or right to inquire as to whether such Breach exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against such sublessee, or, until the Breach has
been cured, against Lessor, for any such rents and other charges so paid by said
sublessee to Lessor.

              (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease;
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior defaults
or breaches of such sublessor under such sublease.

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

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

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

  13.  DEFAULT; BREACH; REMEDIES.

     13.1 DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said default. A "DEFAULT" by Lessee is
defined as a failure by Lessee to observe, comply with or perform any of the
terms, covenants, conditions or rules applicable to Lessee under this Lease. A
"BREACH" by Lessee is defined as the occurrence of any one or more of the
following Defaults, and, where a grace period for cure after notice is specified
herein, the failure by Lessee to cure such Default prior to the expiration of
the applicable grace period, and shall entitle Lessor to pursue the remedies set
forth in Paragraphs 13.2 and/or 13.3:

              (b) Except as expressly otherwise provided in this Lease, the
failure by Lessee to make any payment of Base Rent, Lessee's Share of Common
Area Operating Expenses, or any other monetary payment required to be made by
Lessee hereunder as and when due, the failure by Lessee to provide Lessor with
reasonable evidence of insurance or surety bond required under this Lease, or
the failure of Lessee to fulfill any obligation under this Lease which endangers
or threatens life or property, where such failure continues for a period of
three (3) days following written notice thereof by or on behalf of Lessor to
Lessee.

              (c) Except as expressly otherwise provided in this Lease, the
failure by Lessee to provide Lessor with reasonable written evidence (in duly
executed original form, if applicable) of (i) compliance with Applicable
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service
contracts required under Paragraph 7.1(b), (iii) the rescission of an
unauthorized assignment or subletting per Paragraph 12.1, (iv) a Tenancy
Statement per Paragraphs 16 or 37, (v) the subordination or non-subordination of
this Lease per Paragraph 30, (vi) the guaranty of the performance of Lessee's
obligations under this Lease if required under Paragraphs 1.11 and 37, (vii) the
execution of any document requested under Paragraph 42 (easements), or (viii)
any other documentation or information which Lessor may reasonably require of
Lessee under the terms of this Lease, where any such failure continues for a
period of ten (10) days following written notice by or on behalf of Lessor to
Lessee.

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

              (e) The occurrence of any of the following events: (i) the making
by Lessee of any general arrangement or assignment for the benefit of creditors;
(ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code Section 101 or any
successor statute thereto (unless, in the case of a petition filed against
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment of
a trustee or receiver to take possession of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where
possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this Subparagraph 13.1(e) is contrary to any
applicable law, such provision shall be of no force or effect, and shall not
affect the validity of the remaining provisions.

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

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

                                  Page 8 of 13
<PAGE>   9
the Guarantors that existed at the time of execution of this Lease.

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

              (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee: (i) the worth at the time
of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including, but not limited to, the cost of
recovering possession of the Premises, expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
and that portion of any leasing commission paid by Lessor in connection with
this Lease applicable to the unexpired term of this Lease. The worth at the time
of award of the amount referred to in provision (iii) of the immediately
preceding sentence shall be computed by discounting such amount at the discount
rate of the Federal Reserve Bank of San Francisco or the Federal Reserve Bank
District in which the Premises are located at the time of award plus one percent
(1%). Efforts by Lessor to mitigate damages caused by Lessee's Default or Breach
of this Lease shall not waive Lessor's right to recover damages under this
Paragraph 13.2. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding the unpaid rent and damages as are recoverable therein, or Lessor may
reserve the right to recover all or any part thereof in a separate suit for such
rent and/or damages. If a notice and grace period required under Subparagraphs
13.1(b), (c) or (d) was not previously given, a notice to pay rent or quit, or
to perform or quit, as the case may be, given to Lessee under any statute
authorizing the forfeiture of leases for unlawful detainer shall also constitute
the applicable notice for grace period purposes required by Subparagraph
13.1(b), (c) or (d). In such case, the applicable grace period under the
unlawful detainer statute shall run concurrently after the one such statutory
notice, and the failure of Lessee to cure the Default within the greater of the
two (2) such grace periods shall constitute both an unlawful detainer and a
Breach of this Lease entitling Lessor to the remedies provided for in this Lease
and/or by said statute.

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

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

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

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

     13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or deed of trust covering the Premises.
Accordingly, if any installment of rent or other sum due from Lessee shall not
be received by Lessor or Lessor's designee within ten (10) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to six percent (6%) of such overdue
amount. The Parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance. See Addendum.

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

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

15.  BROKERS' FEES

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

     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

                                  Page 9 of 13
<PAGE>   10
effect at the time of the execution of this Lease.

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

     15.4 REPRESENTATIONS AND WARRANTIES. Lessee and Lessor each represent and
warrant to the other that it has had no dealings with any person, firm, broker
or finder other than as named in Paragraph 1.10(a) in connection with the
negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fee in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnify, protect, defend and hold the other harmless from and against
liability for compensation or charges which may be claimed by any such unnamed
broker, finder or other similar party by reason of any dealings or actions of
the indemnifying Party, including any costs, expenses, and/or attorneys' fees
reasonably incurred with respect thereto.

16.  TENANCY AND FINANCIAL STATEMENTS.

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

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

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

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

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

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

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

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

23.  NOTICES.

     23.1 NOTICE REQUIREMENTS. All notices required or permitted by this Lease
shall be in writing and may be delivered in person (by hand or by messenger or
courier service) or may be sent by regular, certified or registered mail or U.S.
Postal Service Express Mail, with postage prepaid, or by facsimile transmission
during normal business hours, and shall be deemed sufficiently given if served
in a manner specified in this Paragraph 23. The addresses noted adjacent to a
Party's signature on this Lease shall be that Party's address for delivery or
mailing of notice purposes. Either Party may by written notice to the other
specify a different address for notice purposes, except that upon Lessee's
taking possession of the Premises, the Premises shall constitute Lessee's
address for the purpose of mailing or delivering notices to Lessee. A copy of
all notices required or permitted to be given to Lessor hereunder shall be
concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by written notice to Lessee.

     23.2 DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given forty-eight (48) hours after
the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantees next day delivery shall be deemed given twenty-four (24) hours after
delivery of the same to the United States Postal Service or courier. If any
notice is transmitted by facsimile transmission or similar means, the same shall
be deemed served or delivered upon telephone or facsimile confirmation of
receipt of the transmission thereof, provided a copy is also delivered via
delivery 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 of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any such act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. Regardless of Lessor's
knowledge of a Default or Breach at the time of accepting rent, the acceptance
of rent by Lessor shall not be a waiver of any Default or Breach by Lessee of
any provision hereof. Any payment given Lessor by Lessee may be accepted by
Lessor on account of monies or damages due Lessor, notwithstanding any
qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

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

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease. In the event that Lessee holds over in violation of this Paragraph
26 then the Base Rent payable from and after the time of the expiration or
earlier termination of this Lease shall be increased to two hundred percent
(200%) of the Base Rent applicable during the month immediately preceding such
expiration or earlier termination. Nothing contained herein shall be construed
as a consent by Lessor to any holding over by Lessee.*

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

28. COVENANTS AND CONDITIONS. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

29. BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the Parties,
their personal representatives, successors and assigns and be governed by the
laws of the state in which the Premises are located. Any litigation between the
Parties hereto concerning this Lease shall be initiated in the county in which
the Premises are located.

30.  SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

     30.1 SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default pursuant
to Paragraph 13.5. If any Lender shall elect to have this Lease and/or any
Option granted hereby superior to the lien of its Security Device and shall give
written notice thereof to Lessee, this Lease and such Options shall be deemed
prior to such Security Device, notwithstanding the relative dates of the
documentation or recordation thereof.*

     30.2 ATTORNMENT. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires

* See Addendum

                                 Page 10 of 13

<PAGE>   11

ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership, (ii) be subject to any offsets or defenses
which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one (1) month's rent.

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

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

31. ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "PREVAILING PARTY" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. The
attorneys' fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees reasonably
incurred. Lessor shall be entitled to attorneys' fees, costs and expenses
incurred in preparation and service of notices of Default and consultations in
connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting Breach. Broker(s) shall be intended
third party beneficiaries of this Paragraph 31. See Addendum.

32. LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonable times for the purpose of showing the same to
prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the Building, as Lessor
may reasonably deem necessary. Lessor may at any time place on or about the
Premises or Building any ordinary "For Sale" signs and Lessor may at any time
during the last one hundred eighty (180) days of the term hereof place on or
about the Premises any ordinary "For Lease" signs. All such activities of Lessor
shall be without abatement of Rent or liability to Lessee.

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

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

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

36.  CONSENTS.

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

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

37.  GUARANTOR.

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

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

38. QUIET POSSESSION. Upon payment by Lessee of the Rent for the Premises and
the performance of all of the covenants, conditions and provisions on Lessee's
part to be observed and performed under this Lease, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.

39. OPTIONS.

     39.1 DEFINITION. As used in this Lease, the word "OPTION" has the following
meaning: (a) the right to extend the term of this Lease or to renew this Lease
or to extend or renew any lease that Lessee has on other property of Lessor; (b)
the right of first refusal to lease the Premises or the right of first offer to
lease the Premises or the right of first refusal to lease other property of
Lessor or the right of first offer to lease other property of Lessor; (c) the
right to purchase the Premises, or the right of first refusal to purchase the
Premises, or the right of first offer to purchase the Premises, or the right to
purchase other property of Lessor, or the right of first refusal to purchase
other property of Lessor, or the right of first offer to purchase other property
of Lessor.

     39.2 OPTIONS PERSONAL TO ORIGINAL LESSEE. Each Option granted to Lessee in
this Lease is personal to the original Lessee named in Paragraph 1.1 hereof, and
cannot be voluntarily or involuntarily assigned or exercised by any person or
entity other than said original Lessee while the original Lessee is in full and
actual possession of the Premises and without the intention of thereafter
assigning or subletting. The Options, if any, herein granted to Lessee are not
assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

     39.3 MULTIPLE OPTIONS. In the event that Lessee has any multiple Options to
extend or renew this Lease, a 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,
notwithstanding any provision in the grant of Option to the contrary: (i) during
the period commencing with the giving of any notice of Default under Paragraph
13.1 and continuing until the noticed Default is cured, or (ii) during the
period of time any monetary obligation due Lessor from Lessee is unpaid (without
regard to whether notice thereof is given Lessee), or (iii) during the time
Lessee is in Breach of this Lease, or (iv) in the event that Lessor has given to
Lessee three (3) or more notices of separate Default under Paragraph 13.1 during
the twelve (12) month period immediately preceding the exercise of the Option,
whether or not the Defaults are cured.

                                 Page 11 of 13

<PAGE>   12
              (b) The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of Paragraph 39.4(a).

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

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

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

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

43. PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suit for recovery of such sum. If it shall be adjudged

                   ADDENDUM TO STANDARD AIR INDUSTRIAL LEASE

       This Addendum (the "Addendum") is made as of the 3rd day of March, 1999,
between Pacific Gulf Properties Inc., a Maryland corporation ("Lessor") and
NATURAL ALTERNATIVES INTERNATIONAL, INC., a Delaware corporation ("Lessee").

       The parties hereby acknowledge that they are contemporaneously entering
into that certain Lease dated March 3, 1999 (the "Lease"). Unless otherwise
specifically provided in this Addendum, all capitalized terms used herein shall
have the same meanings set forth in the Lease. In the event of any conflict
between the Lease and this Addendum, this Addendum shall control. This Addendum
amends and supplements the Lease as follows:

ADDENDUM PARAGRAPH 6.2(d) [Hazardous Materials]

       "6.2(d) Notwithstanding anything to the contrary contained in Lease
Paragraph 6.2:

               A. Lessee warrants that Lessee's business and all activities to
be performed by Lessee in, on or about the Premises shall comply with all
Applicable Laws respecting Hazardous Substances and Lessee agrees to change any
such activity or install any equipment, safety devices, pollution control
systems and/or other installations as may be required at any time during the
Lease term to comply therewith.

<PAGE>   15

              B. Lessee shall not cause or permit any Hazardous Substance other
than those normally used in the course of its business which are disclosed in
Exhibit C to be brought upon, kept, or used in or about the Premises by Lessee,
its agents, employees, contractors or invitees, without the prior written
consent of Lessor. If Lessee breaches the obligations stated in the preceding
sentence, or if the presence of Hazardous Substance on the Premises caused or
permitted by Lessee or otherwise caused to be located upon the Premises during
the Lease term results in contamination of the Premises or any adjacent
property, then Lessee shall indemnify, defend and hold Lesser harmless from any
and all claims, judgments, damages, penalties, fines, costs, liabilities or
losses (including, without limitation, diminution in value of the Premises
and/or adjacent property, damages for the loss or restriction on use of rentable
or usable space or of any amenity of the Premises and/or adjacent property,
damages arising from any adverse impact on marketing of the Premises and/or
adjacent property, and sums paid in settlement of claims, attorneys' fees,
consultant fees and expert fees) which arise during or after the Lease term
(including any Option Term) as a result of such contamination. This
indemnification of Lessor by Lessee includes, without limitation, costs incurred
in connection with any investigation of site conditions or any cleanup,
remedial, removal or restoration work required by any federal, state or local
governmental agency or political subdivision because of Hazardous Substance
present in the soil or ground water on or under the Premises and/or adjacent
property. Without limiting the foregoing, if the presence of any Hazardous
Substance on the Premises caused or permitted by Lessee results in any
contamination of the Premises and/or adjacent property, Lessee shall promptly
take all actions at its sole expense as are necessary to return the Premises
and/or adjacent property to the condition existing prior to the introduction of
any such Hazardous Substance to the Premises and/or adjacent property, provided
that Lessor's approval of such actions shall first be obtained, which approval
shall not be unreasonably withheld so long as such actions would not potentially
have any material adverse long-term or short-term effect on the Premises or
adjacent property.

              C. Lessor shall have the right, but not the duty, to inspect the
Premises at any time to determine whether Lessee is complying with the
requirements of the Lease (as hereby amended). If Lessee is not in compliance
with the requirements of the provisions of the Lease (as hereby amended)
relating to Hazardous Substances, Lessor shall have the right, but not the
obligation, to immediately enter upon the Premises to remedy any condition
caused by Lessee's failure to comply with the requirements of the Lease (as
hereby amended). Lessor shall use reasonable efforts to minimize interference
with Lessee's business as a result of any such entry by Lessor but shall not be
liable for any interference caused thereby "

ADDENDUM PARAGRAPH 7.2 [Lessor's Obligations]

       The following is hereby added to the end of Paragraph 7.2:

       "However, any such repairs or maintenance which is necessitated by the
       negligence or willful misconduct of Lessee, its servants, agents,
       employees or contractors or anyone claiming under Lessee, or by reason of
       the failure of Lessee to perform or observe any condition or agreement
       contained in this Lease, or caused by alterations, additions or
       improvements made by Lessee or anyone claiming under Lessee, shall be
       made by Lessee or, at Lessor's option, by Lessor at Lessee's sole cost
       and expense. In addition, at Lessor's option, Lessor shall have the
       right, but not the obligation, to maintain any of the service contracts
       otherwise to be maintained by Lessee pursuant to Paragraph 7.1(b) above,
       as an item of Operating Expenses. Notwithstanding anything to the
       contrary contained in this Lease, Lessor shall not be liable to Lessee
       for failure to make repairs as herein specifically required of it unless
       Lessee has previously notified Lessor, in writing, of the need for such
       repairs and Lessor has failed to commence and complete said repairs
       within a reasonable time following receipt of Lessee's written
       notification."

ADDENDUM PARAGRAPH 7.3(a) [Utility Installations]

       The following is hereby added at the end of Paragraph 7.3(a):

       "Notwithstanding anything to the contrary contained herein, no addition,
       alteration, change, installation or improvement shall be made which will
       weaken the structural strength, lessen the value of, interfere or make
       inoperable any portion of the Premises or change the architectural
       appearance of the Premises."

ADDENDUM PARAGRAPH 8.5 (Insurance Policies]

       The following is added to the end of Paragraph 8.5:

       "For any period or periods in which Lessee fails to maintain any
       insurance required hereunder, Base Rent for the first month for any such
       period in which Lessee is notified by Lessor of such failure shall be
       increased by One Hundred Dollars ($100). The foregoing shall not limit
       any other right or remedy of Lessor or relieve Lessee of its obligations
       regarding maintenance of insurance as provided by the Lease."

<PAGE>   16

ADDENDUM PARAGRAPH 9.2

       The following is added at the end of Paragraph 9.2:

       "Lessor may terminate this Lease in the event any repair or
       reconstruction is restricted by any governmental authority."

ADDENDUM PARAGRAPH 12.1(f) [Recapture]

       New Subparagraph 12.1(f) is hereby added as follows:

       "(f) In addition to Lessor's right of approval of any proposed assignment
       or subletting and without limiting the other provisions of this Paragraph
       12, Lessor shall have the option, in the event of any proposed assignment
       or subletting, to terminate the Lease as to the affected portion of the
       Premises as of the proposed effective date of the proposed assignment or
       subletting set forth in Lessee's notice. Such option to terminate shall
       be exercised, if at all, by Lessor giving Lessee written notice thereof
       within sixty (60) days following Lessor's receipt of Lessee's written
       request. In the event of such termination by Lessor, from and after the
       effective date of such termination, Lessor and Lessee shall have no
       further obligations or liabilities to each other with respect to the
       affected portion of the Premises, except with respect to obligations or
       liabilities which have accrued as of, or survive, such termination (in
       the same manner as if such termination date were the date originally
       fixed for the expiration of the Lease term). Without in any manner
       limiting the rights of Lessor, following any such termination by Lessor,
       Lessor may lease the affected portion of the Premises to the prospective
       assignee or subtenant proposed by Lessee, without liability to the Lessee
       Lessor's failure to exercise such termination right as herein provided
       shall not be construed as Lessor's consent to the proposed assignment or
       subletting."

ADDENDUM PARAGRAPH 13.4 [Late Fee]

       The words "six percent (6%)" contained in Paragraph 13.4 are hereby
       deleted, and the words "ten percent (10%)" are substituted in lieu
       thereof.

ADDENDUM PARAGRAPH 15 [Broker's Fees]

       Paragraphs 15.2 and 15.3 are hereby deleted and the following is
       substituted in lieu thereof.

       "Lessor shall be responsible for payment of the commission owing to such
       Brokers in connection with this Lease pursuant to separate written
       agreement."

ADDENDUM PARAGRAPH 17 [Lessor's Liability]

       The following is added at the end of Paragraph 17 as follows:

       "Lessee hereby agrees that, in the event of any actual or alleged
       failure, breach or default hereunder by Lessor, Lessee's sole and
       exclusive remedy shall be against the Lessor's interest in the Industrial
       Center. Lessee agrees that the obligations of Lessor under this Lease do
       not constitute personal obligations of the individual directors, officers
       or shareholders of Lessor, and Lessee shall not seek recourse against the
       individual directors, officers or shareholders of Lessor or any of their
       personal assets for satisfaction of any liability with respect to this
       Lease."

ADDENDUM PARAGRAPH 21 [Rent Defined]

       The following is added at the end of Paragraph 21:

       "Without limiting the foregoing, any fees or costs incurred by Lessor in
       connection with the execution and enforcement of Lessor's remedies,
       including, without limitation, the cost of credit reports, asset
       searches, fees for returned checks and insurance compliance charges shall
       be promptly reimbursed by Lessee to Lessor on demand, and such amounts
       shall be considered additional rent."

ADDENDUM PARAGRAPH 25 [Recording]

       Paragraph 25 of the Lease is hereby deleted in its entirety, and the
       following is inserted in place thereof:

       "Neither this Lease nor a short form of memorandum of this Lease shall be
       recorded in the office of any county recorder without Lessor's express
       written consent. In the event of any such recordation, Lessee shall be
       solely responsible for any documentary transfer taxes or other taxes
       relating to or arising out of any such recordation."

ADDENDUM PARAGRAPH 26 [Holding Over]

       Paragraph 26 of the Lease is hereby deleted in its entirety, and the
       following is inserted in place thereof:

                                      -3-
<PAGE>   17

       "Lessee has no right to retain possession of the Premises or any part
       thereof beyond the expiration or earlier termination of this Lease. Any
       holding over by Lessee after the expiration or earlier termination of
       this Lease shall be construed to be a tenancy at sufferance on all of
       the terms and conditions set forth herein to the extent not inconsistent
       with a tenancy at sufferance, provided that the Base Rent for such
       holdover period shall be an amount equal to one hundred twenty-five
       percent (125%) the monthly Base Rent due for the last full month of the
       Term. Acceptance by Lessor of rent or any other sum payable hereunder
       after such expiration or earlier termination shall not result in an
       extension or renewal of this Lease. If Lessee fails to surrender the
       Premises upon the expiration or earlier termination of this Lease, Lessee
       shall indemnify, defend and hold harmless Lessor from and against all
       loss, damage, cost, liability or expense (including, without limitation,
       attorneys' fees and expenses) resulting from or relating to such failure
       to surrender the Premises including, without limitation, any claim made
       by any succeeding tenant."

ADDENDUM PARAGRAPH 30.1 [Subordination]

       The following is inserted at the end of Paragraph 30.1:

       "In the event of Lessor's default with respect to any such obligation,
       Lessee will give any Lender whose name and address have been furnished
       Lessee in writing for such purpose notice of Lessor's default and allow
       such Lender thirty (30) days (or if more than thirty (30) days is
       required to effect such cure, such additional time as may be necessary)
       following receipt of such notice for the cure of said default before
       invoking any remedies Lessee may have by reason thereof."

ADDENDUM PARAGRAPH 31 [Attorney's Fees]

       Paragraph 31 is modified as follows

       The last sentence of Paragraph 31 is hereby deleted, and the following is
       hereby added at the end of Paragraph 31:

       "Attorney's fees reasonably incurred by Lessor shall include attorneys
       fees and costs in connection with asset searches or other investigations
       of Lessee in connection with the execution and enforcement of Lessor's
       remedies."

ADDENDUM PARAGRAPH 49 [Lessor as Real Estate Investment Trust]

       The following is hereby added as a new Paragraph 49:

       "Lessor hereby advises Lessee that Lessor is qualified as a real estate
       investment trust under the provisions of the Internal Revenue Code of
       1986, as amended, and that the maintaining of such status and the
       avoiding of any activity which might cause a penalty tax to be applied is
       of material concern to Lessor. Accordingly, Lessee agrees to make any
       modifications or amendments to this Lease requested by Lessor that may be
       necessary for Lessor to maintain its status as a real estate investment
       trust or in order for it to avoid a penalty tax; provided, however, that
       Lessee shall have no obligation to enter into any such modification or
       amendment that would materially alter or affect Lessee's rights, duties,
       or obligations under this Lease. If Lessee declines to modify or amend
       this Lease for any reason in a manner which Lessor determines, in the
       good faith exercise of its reasonable business judgment, is necessary to
       maintain its status as a real estate investment trust, Lessor shall have
       the right to terminate this Lease by written notice delivered to Lessee.
       Further, in the event Lessor consents to any assignment or sublease of
       this Lease, Lessee no amount received or accrued, directly or indirectly,
       with respect to such assignment or sublease shall depend in whole or in
       part on the income or profits of the assignee or sublessee, or any other
       person deriving income from the Premises."

       49. MONTHLY RENT: The monthly rental rate shall be as follows.

                    03/15/99 - 03/31/00            $10,000.00

       50. NNN CHARGES: NNN charges are estimated at $0.85 PSF ($1700.00/MO) and
       shall be paid monthly as additional rent.

       51. LESSOR IMPROVEMENTS: Lessor shall, at Lessor's sole cost and expense,
       provide the following:

            a. Paint the existing office area with Lessor's standard paint.

            b. Install carpet in the existing office area with Lessor's standard
               carpet.

               order.

       ALL ADDITIONAL MODIFICATIONS, REFURBISHMENTS AND/OR IMPROVEMENTS SHALL BE
       AT LESSEE'S SOLE COST AND EXPENSE.

                                      -4-

                      LEASE EXTENSION AGREEMENT                    July 13, 1999

THAT CERTAIN LEASE DATED March 3, 1999 BY AND BETWEEN: PACIFIC GULF PROPERTIES,
INC., a Maryland corporation as LESSOR, and NATURAL ALTERNATIVES, INC., a
Delaware corporation as LESSEE, for the premises located at 1211 Park Center
Drive, Suite C, Vista, CA 92083, a unit of 20,000 sq.ft., shall be extended for
a period of three (3) years and five (5) months, commencing April 1, 2000 and
terminating on August 31, 2003 on all terms and conditions with the following
modifications:

PARAGRAPH 4 - BASE RENT: The monthly rental rate through the term of this Lease
Extension shall be as follows:

                        4/1/00 - 8/31/01   $10,400.00
                        9/1/01 - 8/31/02   $10,800.00
                        9/1/02 - 8/31/03   $11,200.00

ADDENDUM, #50 - NNN CHARGES: The NNN charges are estimated in 1999 at $.0798PSF

TENANT IMPROVEMENTS: Lessor shall approve Lessee to construct underground
cabling at Lessee's sole cost and expense, between 1211 Park Center Drive, Suite
C and 1215 Park Center Drive, Suites C/D/E, with the following conditions:

         a.       Lessee shall submit plans of proposed improvement to Lessor
                  for Lessor's prior approval.

         b.       All work must be completed by a licensed, insured contractor
                  and be constructed per requirements of the City of Vista.

OPTION TO EXTEND: Lessee shall have the option to extend the term of this Lease
("Option") on all of the terms, conditions, covenants and provisions, contained
in this Lease, except for the Monthly Rent, for two (2) additional terms of five
(5) years each following the Termination Date. The Option Term shall commence on
the day immediately following the Termination Date.

Lessee may exercise the Option by giving written notice of exercise of the
Option to Lessor at least one hundred twenty (120) days before the Termination
Date. If Lessee is in default on the date of giving the Option Notice, the
Option Notice shall be totally ineffective. If the Option Notice is not given,
the Option shall automatically expire and be of no further force or effect.

The Option granted to Lessee in this Lease is personal to the original Lessee
and may be exercised only by the original Lessee while physically occupying the
Premises. The Option may not be exercised or assigned, voluntarily or
involuntarily, by or to any person or entity other than Lessee. Any consent by
Lessor to an assignment of the Lease or a sublet of the Premises, or any portion
thereof, shall not be construed as a waiver of this prohibition.

Monthly Rent during each Option period shall be at Fair Market Value, as
determined by Lessor, at the time Lessor receives the Option Notice. In the
event the Lessor and Lessee cannot agree on the new base rent, the matter shall
be submitted for decision to a panel of three arbitrators. Lessor and Lessee
shall each appoint one arbitrator who shall by profession be a licensed
commercial real estate broker or an MAI real estate appraiser, and who shall be
familiar with the premises Building and have been active in the brokering or
appraisal of properties in an area within a three (3) mile radius of the
Premises. Each such arbitrator shall be appointed within fifteen (15) days after
Lessee's notice to Lessor of its election to have New Base Rent determined by
this arbitration procedure. The two arbitrators so appointed shall within
fifteen (15) days of the date of the appointment of the last appointed
arbitrator agree upon and appoint a third arbitrator who shall be qualified
under the same criteria set forth hereinabove for qualification of the initial
two arbitrators. Failing such agreement, either Lessor or Lessee shall have the
right to petition for the appointment of the third arbitrator by the Presiding
Judge of the Superior Court of the County of San Diego. The three arbitrators
shall within thirty (30) days of the appointment of the third arbitrator reach a
decision as to whether the parties shall use Lessor's or Lessee's proposed New
Base Rent, and shall notify Lessor and Lessee therefore. The decision of the
majority of the three arbitrators shall be binding upon Lessor and Lessee. The
cost of the arbitration shall be paid by Lessor and Lessee equally. In no event,
shall the monthly rent for the Option term be less than a four percent (4%)
increase over the previous year's monthly rent. Upon agreement to the terms of
the Option, Lessor shall immediately execute an Extension of Lease Agreement.
All rights of Lessee with respect to the Option shall terminate and be of no
further force or effect if Lessor and Lessee do not come to agreement on the
Option. Neither Lessor nor Lessee shall have the right to have a court or third
party set the Monthly Rent.
