     2.1    LETTING. Lessor hereby leases to Lessee, and Lessee hereby leases
from Lessor, the Premises, for the term, at the rental, and upon all of the
terms, covenants and conditions set forth in this Lease. Unless otherwise
provided herein, any statement of size set forth in this Lease, or that may
have been used in calculating Rent, is an approximation which the Parties agree
is reasonable any payments based thereon are not subject to revision whether or
not the actual is more or less.

     2.2    CONDITION. Lessor shall deliver that portion of the Premises
contained within the Building ("UNIT") to Lessee broom clean and free of debris
on the Commencement Date or the Early Possession Date, whichever first occurs
("START DATE"), and, so long as the required service contracts described in
Paragraph 7.1(b) below are obtained by Lessee and in effect within thirty days
following the Start Date, warrants that the existing electrical, plumbing, fire
sprinkler, lighting, heating, ventilating and air conditioning systems
("HVAC"), loading doors, if any, and all other such elements in the Unit, other
than those constructed by Lessee, shall be in good operating condition on said
date and that the structural elements of the roof, bearing walls and foundation
of the Unit shall be free of material defects. If a non-compliance with such
warranty exists as of the Start Date, or if one of such systems or elements
should malfunction or fail within the appropriate warranty period, Lessor
shall, as Lessor's sole obligation with respect to such matter, 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, malfunction or failure, rectify same at Lessor's expense. The
warranty periods shall be as follows: (i) 6 months as to the HVAC systems, and
(ii) 30 days as to the remaining systems and other elements of the Unit. If
Lessee does not give Lessor the required notice within the appropriate warranty
period, correction of any such non-compliance, malfunction or failure shall be
the obligation of Lessee at Lessee's sole cost and expense (except for the
repairs to the fire sprinkler systems, roof, foundations, and/or bearing walls
- see Paragraph 7).

     2.3    COMPLIANCE. Lessor warrants that the improvements on the Premises
and the Common Areas comply with the building codes that were in effect at the
time that each such improvement, or portion thereof, was constructed, and also
with all applicable laws, covenants or restrictions of record, regulations, and
ordinances in effect on the Start Date ("APPLICABLE REQUIREMENTS"). Said
warranty does not apply to the use to which Lessee will put the Premises or to
any Alterations or Utility Installations (as defined in Paragraph 7.3(a)) made
or to be made by Lessee. NOTE: LESSEE IS RESPONSIBLE FOR DETERMINING WHETHER OR
NOT THE APPLICABLE REQUIREMENTS,

                                     PAGE 1

<PAGE>   2
AND ESPECIALLY THE ZONING, ARE APPROPRIATE FOR LESSEE'S INTENDED USE, AND
ACKNOWLEDGES THAT PAST USES OF THE PREMISES MAY NO LONGER BE ALLOWED. If the
Premises do not comply with said warranty, Lessor shall, except as otherwise
provided, promptly after receipt of written notice from Lessee setting forth
with specificity the nature and extent of such non-compliance, rectify the same
at Lessor's expense. If Lessee does not give Lessor written notice of a
non-compliance with this warranty within 6 months following the Start Date,
correction of that non compliance shall be the obligation of Lessee at Lessee's
sole cost and expense. If the Applicable Requirements are hereafter changed so
as to require during the term of this Lease the construction of an addition to
or an alteration of the Unit, Premises and/or Building, the remediation of any
Hazardous Substance, or the reinforcement or other physical modification of
the Unit, Premises and/or Building ("CAPITAL EXPENDITURE"), Lessor and Lessee
shall allocate the cost of such work as follows:

                (a)     Subject to Paragraph 2.3(c) below, if such Capital
Expenditures are required as a result of the specific and unique use of the
Premises by Lessee as compared with uses by tenants in general, Lessee shall be
fully responsible for the cost thereof, provided, however that is such Capital
Expenditure is required during the last 2 years of this Lease and the cost
thereof exceeds 6 months' Base Rent, Lessee may instead terminate this Lease
unless Lessor notifies Lessee, in writing, within 10 days after receipt of
Lessee's termination notice that Lessor has elected to pay the difference
between the actual cost thereof and the amount equal to 6 months' Base Rent. If
Lessee elects termination, Lessee shall immediately cease the use of the
Premises which requires such Capital Expenditure and deliver to Lessor written
notice specifying a termination date at least 90 days thereafter. Such
termination date shall, however, in no event be earlier than the last day that
Lessee could legally utilize the Premises commencing such Capital Expenditure.

                (b)     If such Capital Expenditure is not the result of the
specific and unique use of the Premises by Lessee (such as, governmentally
mandated seismic modifications), then Lessor and Lessee shall allocate the
obligation to pay for the portion of such costs reasonably attributable to the
Premises pursuant to the formula set out in Paragraph 7.1(d); provided,
however, that is such Capital Expenditure is required during the last 2 years
of this Lease or if Lessor reasonably determines that it is not economically
feasible to pay its share thereof, Lessor shall have the option to terminate
this Lease upon 90 days prior written notice to Lessee unless Lessee notifies
Lessor in writing, within 10 days after receipt of Lessor's termination notice
that Lessee will pay for such Capital Expenditure. If Lessor does not elect to
terminate, and fails to tender its share of any such Capital Expenditure,
Lessee may advance such funds and deduct same, with interest, from Rent until
Lessor's share of such costs have been fully paid. If Lessee is unable to
finance Lessor's share, or if the balance of the rent due and payable for the
remainder of this Lease is not sufficient to fully reimburse Lessee on an
offset basis, Lessee shall have the right to terminate this Lease upon 30 days
written notice to Lessor.

                (c)     Notwithstanding the above, the provisions concerning
Capital Expenditures are intended to apply only to non-voluntary, unexpected,
and new Applicable Requirements. If the Capital Expenditures are instead
triggered by Lessee as a result of an actual or proposed change in use, change
in intensity of use, or modification to the Premises then, and in that event,
Lessee shall be fully responsible for the cost thereof, and Lessee shall not
have any right to terminate this Lease.

        2.4     ACKNOWLEDGEMENTS. Lessee acknowledges that: (a) it has been
advised by Lessor and/or Brokers to satisfy itself with respect to the
condition of the Premises (including but not limited to the electrical, HVAC
and fire sprinkler systems, security, environmental aspects, and compliance
with Applicable Requirements and the Americans with Disabilities Act), and
their suitability for Lessee's intended use, (b) Lessee has made such
investigation as it deems necessary with reference to such matters and assumes
all responsibility therefor as the same relate to its occupancy of the
Premises, and (c) neither Lessor, Lessor's agents, nor Brokers have made any
oral or written representations or warranties with respect to said matters
other than as set forth in this Lease. In addition, Lessor acknowledges that:
(i) Brokers have made no representations, promises or warranties concerning
Lessee's ability to honor the Lease or suitability to occupy the Premises, and
(ii) it is Lessor's sole responsibility to investigate the financial capability
and/or suitability of all proposed tenants.

        2.5     LESSEE AS PRIOR OWNER/OCCUPANT. the warranties made by Lessor
in Paragraph 2 shall be of no force or effect if immediately prior to the Start
Date Lessee was the owner or occupant of the Premises. In such event, Lessee
shall be responsible for any necessary corrective work.

        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." Lessor may regulate the loading and unloading of vehicles by
adopting Rules and Regulations as provided in Paragraph 2.9. No vehicles other
than Permitted Size Vehicles may be parked in the Common Area without the prior
written permission of Lessor.

                (a)     Lessee shall not permit or allow any vehicles that
belong to or are controlled by Lessee or Lessee's employees, suppliers,
shippers, customers, contractors or invitees to be loaded, unloaded, or parked
in areas other than those designated by Lessor for such activities.

                (b)     Lessee shall not service or store any vehicles in the
Common Areas.

                (c)     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 remove or tow away the vehicle involved and charge the cost to Lessee,
which cost shall be immediately payable upon demand by Lessor.

        2.7     COMMON AREAS -- DEFINITION. The term "COMMON AREAS" is defined
as all areas and facilities outside the Premises and within the exterior
boundary line of the Project and interior utility raceways and installations
within the Unit that are provided and designated by the Lessor from time to
time for the general non-exclusive use of Lessor, Lessee and other tenants of
the Project and their respective employees, suppliers, shippers, customers,
contractors and invitees, including parking areas, loading and unloading areas,
trash areas, roadways, walkways, driveways and landscaped areas.

        2.8     COMMON AREAS -- LESSEE'S RIGHTS. Lessor grants to Lessee, for
the benefit of Lessee and its employees, suppliers, shippers, contractors,
customers and invitees, during the term of this Lease, the non-exclusive right
to use, in common with others entitled to such use, the Common Areas as they
exist from time to time, subject to any rights, powers, and privileges reserved
by Lessor under the terms hereof or under the terms of any rules and
regulations or restrictions governing the use of the Project. 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.

        2.9     COMMON AREAS -- RULES AND REGULATIONS. Lessor or such other
person(s) as Lessor may appoint shall have the exclusive control and management
of the Common Areas and shall have the right, from time to time, to establish,
modify, amend and enforce reasonable rules and regulations ("RULES AND
REGULATIONS") 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 Project and their invitees. Lessee agrees to abide by and conform to all
such Rules and Regulations, and to cause its employees, suppliers, shippers,
customers, contractors and invitees to so abide and conform. Lessor shall not
be responsible to Lessee for the non-compliance with said Rules and Regulations
by other tenants of the Project.

        2.10    COMMON AREAS -- CHANGES. Lessor shall have the right, in
Lessor's sole discretion, from time to time:

                (a)     To make changes to the Common Areas including, without
limitation, changes in the location, size, shape and number of driveways,
entrances, parking spaces, parking areas, loading and unloading areas, ingress,
egress, direction of traffic, landscaped areas, walkways and utility raceways;

                (b)     To close temporarily any of the Common Areas for
maintenance purposes so long as reasonable access to the Premises remain
available;

                (c)     To designate other land outside the boundaries of the
Project to be a part of the Common Areas;

                (d)     To add additional buildings and improvements to the
Common Areas;

                                     PAGE 2

<PAGE>   3
            (e)   To use the Common Areas while engaged in making additional
improvements, repairs or alterations to the Project, or any portion thereof; and

            (f)   To do and perform such other acts and make such other changes
in, to or with respect to the Common Areas and Project as Lessor may, in the
exercise of sound business judgment, deem to be appropriate.

3.    TERM.

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

      3.2   EARLY POSSESSION. If Lessee totally or partially occupies the
Premises prior to the Commencement Date, the obligation to pay Base Rent shall
be abated for the period of such early possession. All other terms of this
Lease (including but not limited to the obligations to pay Lessee's Share of
Common Area Operating Expenses, Real Property Taxes and insurance premiums and
to maintain the Premises) shall, however, be in effect during such period. Any
such early possession shall not affect the Expiration Date.

      3.3   DELAY IN POSSESSION. Lessor agrees to use its best commercially
reasonable efforts to deliver possession of the Premises to Lessee by the
Commencement Date. If, despite said efforts, Lessor is unable to deliver
possession as agreed, Lessor shall not be subject to any liability therefor,
nor shall such failure affect the validity of this Lease. Lessee shall not,
however, be obligated to pay Rent or perform its other obligations until it
receives possession of the Premises. If possession is not delivered within 60
days after the Commencement Date, Lessee may, at its option, by notice in
writing within 10 days after the end of such 60 day period, cancel this Lease,
in which event the Parties shall be discharged from all obligations hereunder.
If such written notice is not received by Lessor within said 10 day period,
Lessee's right to cancel shall terminate. Except as otherwise provided, if
possession is not tendered to Lessee by the Start Date and Lessee does not
terminate this Lease, as aforesaid, any period of rent abatement that Lessee
would otherwise have enjoyed shall run from the date of delivery of possession
and continue for a period equal to what Lessee would otherwise have enjoyed
under the terms hereof, but minus any days of delay caused by the acts or
omissions of Lessee. If possession of the Premises is not delivered within 4
months after the Commencement Date, this Lease shall terminate unless other
agreements are reached between Lessor and Lessee, in writing.

      3.4   LESSEE COMPLIANCE. Lessor shall not be required to tender
possession of the Premises to Lessee until Lessee complies with its obligation
to provide evidence of insurance (Paragraph 8.5). Pending delivery of such
evidence, Lessee shall be required to perform all of its obligations under this
Lease from and after the Start Date, including the payment of Rent,
notwithstanding Lessor's election to withhold possession pending receipt of
such evidence of insurance. Further, if Lessee is required to perform any other
conditions prior to or concurrent with the Start Date, the Start Date shall
occur but Lessor may elect to withhold possession until such conditions are
satisfied.

4.    RENT.

      4.1   RENT DEFINED. All monetary obligations of Lessee to Lessor under
the terms of this Lease (except for the Security Deposit) are deemed to be rent
("RENT").

      4.2   COMMON AREA OPERATING EXPENSES. Lessee shall pay to Lessor during
the term hereof, in addition to the Base Rent, Lessee's Share (as specified in
Paragraph 1.6) of all Common Area Operating Expenses, as hereinafter defined,
during each calendar year of the term of this Lease, in accordance with the
following provisions: See Addendum 56

            (a)   "COMMON AREA OPERATING EXPENSES" are defined, for purposes of
this Lease, as all costs incurred by Lessor relating to the ownership and
operation of the Project, including, but not limited to, the following:

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

                          (aa)  The Common Areas and Common Area improvements,
                          including parking areas, loading and unloading areas,
                          trash areas, roadways, parkways, walkways, driveways,
                          landscaped areas, bumpers, irrigation systems, Common
                          Area lighting facilities, fences and gates, elevators,
                          roofs, and roof drainage systems.
                          (bb) Exterior signs and any tenant directories.
                          (cc)  Any fire detection and/or sprinkler systems.

                  (ii)    The cost of water, gas, electricity and telephone to
                          service the Common Areas and any utilities not
                          separately metered.

                  (iii)   Trash disposal, pest control services, property
                          management, security services, and the costs of any
                          environmental inspections.

                  (iv)    Reserves set aside for maintenance and repair of
                          Common Areas.

                  (v)     Real Property Taxes (as defined in Paragraph 10).

                  (vi)    The cost of the premiums for the insurance maintained
                          by Lessor pursuant to Paragraph 8.

                  (vii)   Any deductible portion of an insured loss concerning
                          the Building or the Common Areas.

                  (viii)  The cost of any Capital Expenditure to the Building
                          or the Project not covered under the provisions of
                          Paragraph 2.3 provided; however, that Lessor shall
                          allocate the cost of any such Capital Expenditure
                          over a 12 year period and Lessee shall not be
                          required to pay more than Lessee's Share of 1/144th
                          of the cost of such Capital Expenditure in any given
                          month.

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

            (b)   Any Common Area Operating Expenses and Real Property Taxes
that are specifically attributable to the Unit, the Building or to any other
building in the Project or to the operation, repair and maintenance thereof,
shall be allocated entirely to such Unit, Building, or 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 Project.

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

            (d)   Lessee's Share of Common Area Operating Expenses shall be
payable by Lessee within 10 days after a reasonably detailed statement of
actual expenses is presented to Lessee. 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 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 the preceding year exceed Lessee's Share as indicated on such
statement, Lessor shall credit the amount of such over payment against Lessee's
Share of Common Area Operating Expenses next becoming due. If Lessee's payments
under this Paragraph 4.2(d) during the preceding year were less than Lessee's
Share as indicated on such statement, Lessee shall pay to Lessor the amount of
the deficiency within 10 days after delivery by Lessor to Lessee of the
statement. See Addendum 58

      4.3   PAYMENT. Lessee shall cause payment of Rent to be received by
Lessor in lawful money of the United States, without offset or deduction
(except as specifically permitted in this Lease), on or before the day on which
it is due. Rent for any period during the term hereof which is for less than
one full calendar month shall be prorated based upon the actual number of days
of said month. Payment of Rent shall be made to Lessor at its address stated
herein or to such other persons or place as Lessor may from time to time
designate in writing. Acceptance of a payment which is less than the amount
then due shall not be a waiver of Lessor's rights to the balance of such Rent,
regardless of Lessor's endorsement of any check so stating. In the event that
any check, draft, or other instrument of payment given by Lessee to Lessor is
dishonored for any reason, Lessee agrees to pay to Lessor the sum of $25 in
addition to any late charges which may be due.

5.    SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof
the Security Deposit as security for Lessee's faithful performance of its
obligations under this Lease. If Lessee fails to pay Rent, or otherwise
Defaults under this Lease, Lessor may use,

                                     PAGE 3

<PAGE>   4
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,
expense, loss or damage which Lessor may suffer or incur by reason thereof. If
Lessor uses or applies all or any portion of the Security Deposit, Lessee shall
within 10 days after written request therefor deposit monies with Lessor
sufficient to restore said Security Deposit to the full amount required by this
Lease. If the Base Rent increases during the term of this Lease, Lessee shall,
upon written request from Lessor, deposit additional monies with Lessor so that
the total amount of the Security Deposit shall at all times bear the same
proportion to the increased Base Rent as the initial Security Deposit bore to
the initial Base Rent. Should the Agreed Use be amended to accommodate a
material change in the business of Lessee or to accommodate a sublessee or
assignee, Lessor shall have the right to increase the Security Deposit to the
extent necessary, in Lessor's reasonable judgment, to account for any increased
wear and tear that the Premises may suffer as a result thereof. If a change in
control of Lessee occurs during this Lease and following such change the
financial condition of Lessee is, in Lessor's reasonable judgment,
significantly reduced, Lessee shall deposit such additional monies with Lessor
as shall be sufficient to cause the Security Deposit to be at a commercially
reasonable level based on such change in financial condition. Lessor shall not
be required to keep the Security Deposit separate from its general accounts.
Within 14 days after the expiration or termination of this Lease, if Lessor
elects to apply the Security Deposit only to unpaid Rent, and otherwise within
30 days after the Premises have been vacated pursuant to Paragraph 7.4(c)
below, Lessor shall return that portion of the Security Deposit not used or
applied by Lessor. No part of the Security Deposit shall be considered to be
held in trust, to bear interest or to be prepayment for any monies to be paid
by Lessee under this Lease.

6.   USE.

     6.1  USE. Lessee shall use and occupy the Premises only for the Agreed
Use, 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 damage, waste or nuisance, or that disturbs
occupants of or causes damage to neighboring premises or properties. Lessor
shall not unreasonably withhold or delay its consent to any written request for
a modification of the Agreed Use, so long as the same will not impair the
structural integrity of the improvements on the Premises or the mechanical or
electrical systems therein, and/or is not significantly more burdensome to the
Premises. If Lessor elects to withhold consent, Lessor shall within 7 days
after such request give written notification of same, which notice shall
include an explanation of Lessor's objections to the change in the Agreed Use.

     6.2  HAZARDOUS SUBSTANCES. SEE ADDENDUM 57.

          (a)  REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS SUBSTANCE"
as used in this Lease shall mean any product, substance, or waste whose
presence, use, manufacture, disposal, transportation, or release, 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 potentially liability of Lessor to
any governmental agency or third party under any applicable statute or common
law theory. Hazardous Substances shall include, but not be limited to,
hydrocarbons, petroleum, gasoline, and/or crude oil or any products,
by-products or fractions thereof. Lessee shall not engage in any activity in or
on the Premises which constitutes a Reportable Use of Hazardous Substances
without the express prior written consent of Lessor and timely compliance (at
Lessee's expense) with all Applicable Requirements. "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/or (iii) the presence at the Premises of a
Hazardous Substance with respect to which any Applicable Requirements requires
that a notice be given to persons entering or occupying the Premises or
neighboring properties. Notwithstanding the foregoing, Lessee may use any
ordinary and customary materials reasonably required to be used in the normal
course of the Agreed use, so long as such use is in compliance with all
Applicable Requirements, is not a Reportable Use, and does not expose the
Premises or neighboring property to any meaningful risk of contamination or
damage or expose Lessor to any liability therefor. In addition, Lessor may
condition its consent to any Reportable Use upon receiving such additional
assurances as Lessor reasonably deems necessary to protect itself, the public,
the Premises and/or the environment against damage, contamination, injury
and/or liability, including, but not limited to, the installation (and removal
on or before Lease expiration or termination) of protective modifications (such
as concrete encasements) and/or increasing the Security Deposit.

          (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, other than as previously consented to by Lessor, Lessee
shall immediately give written notice of such fact to Lessor, and provide
Lessor with a copy of any report, notice, claim or other documentation which it
has concerning the presence of such Hazardous Substance.

          (c)  LESSEE REMEDIATION. Lessee shall not cause or permit any
Hazardous Substance to be spilled or released in, on, under, or about the
Premises (including through the plumbing or sanitary sewer system) and shall
promptly, at Lessee's expense, take all investigatory and/or remedial action
reasonably recommended, whether or not formally ordered or required, for the
cleanup of any contamination of, and for the maintenance, security and/or
monitoring of the Premises or neighboring properties, that was caused or
materially contributed to by Lessee, or pertaining to or involving any
Hazardous Substance brought onto the Premises during the term of this Lease, by
or for Lessee, or any third party.

          (d)  LESSEE INDEMNIFICATION. Lessee shall indemnify, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, harmless from
and against any and all loss of rents and/or damages, liabilities, judgments,
claims, expenses, penalties, and attorneys' and consultants' fees arising out of
or involving any Hazardous Substance brought onto the Premises by or for Lessee,
or any third party (provided, however, that Lessee shall have no liability under
this Lease with respect to underground migration of any Hazardous Substance
under the Premises from areas outside of the Project). Lessee's obligations
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, removal, remediation, restoration and/or abatement, and
shall survive the expiration or 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.

          (e)  LESSOR INDEMNIFICATION. Lessor and its successors and assigns
shall indemnify, defend, reimburse and hold Lessee, its employees and lenders,
harmless from and against any and all environmental damages, including the cost
of remediation, which existed as a result of Hazardous Substances on the
Premises prior to the Start Date or which are caused by the gross negligence or
willful misconduct of Lessor, its agents or employees. Lessor's obligations, as
and when required by the Applicable Requirements, shall include, but not be
limited to, the cost of investigation, removal, remediation, restoration and/or
abatement, and shall survive the expiration or termination of this Lease.

          (f)  INVESTIGATIONS AND REMEDIATIONS. Lessor shall retain the
responsibility and pay for any investigations or remediation measures required
by governmental entities having jurisdiction with respect to the existence of
Hazardous Substances on the Premises prior to the Start Date, unless such
remediation measures is required as a result of Lessee's use (including
"Alterations", as defined in paragraph 7.3(a) below) of the Premises, in which
event Lessee shall be responsible for such payment. Lessee shall cooperate
fully in any such activities at the request of Lessor, including allowing
Lessor and Lessor's agents to have reasonable access to the Premises at
reasonable times in order to carry out Lessor's investigative and remedial
responsibilities.

          (g)  LESSOR TERMINATION OPTION. If a Hazardous Substance
Condition (see Paragraph 9.1(e)) occurs during the term of this Lease, unless
Lessee is legally responsible therefor (in which case Lessee shall make the
investigation and remediation thereof required by the Applicable Requirements
and this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 6.2(d) 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 remediate such condition exceeds 12 times the then
monthly Base Rent or $100,000, whichever is greater, give written notice to
Lessee, within 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 60 days following the date of such notice. In the event
Lessor elects to give a termination notice, Lessee may, within 10 days
thereafter, give written notice to Lessor of Lessee's commitment to pay the
amount by which the cost of the remediation of such Hazardous Substance
Condition exceeds any amount equal to 12 times

                                     PAGE 4

<PAGE>   5
the then monthly Base Rent or $100,000, whichever is greater. Lessee shall
provide Lessor with said funds or satisfactory assurance thereof within 30 days
following such commitment. In such event, this Lease shall continue in full
force and effect, and Lessor shall proceed to make such 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 provided, this Lease shall terminate as of the date specified in Lessor's
notice of termination.

     6.3  LESSEE'S COMPLIANCE WITH APPLICABLE REQUIREMENTS. Except as otherwise
provided in this Lease, Lessee shall, at Lessee's sole expense, fully,
diligently and in a timely manner, materially comply with all Applicable
Requirements, the requirements of any applicable fire insurance underwriter or
rating bureau, and the recommendations of Lessor's engineers and/or consultants
which relate in any manner to the Premises, without regard to whether said
requirements are now in effect or become effective after the Start Date. Lessee
shall, within 10 days after receipt of Lessor's written request, provide Lessor
with copies of all permits and other documents, and other information
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 the failure
of Lessee or the Premises to comply with any Applicable Requirements.

     6.4  INSPECTION; COMPLIANCE. Lessor and Lessor's "LENDER" (as defined in
Paragraph 30) and consultants shall have the right to enter into 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. The cost of any such inspections shall be paid by
Lessor, unless a violation of Applicable Requirements, or a contamination is
found to exist or be imminent, or the inspection is requested or ordered by a
governmental authority. In such case, Lessee shall upon request reimburse Lessor
for the cost of such inspection, so long as such inspection is reasonably
related to the violation or contamination.

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

    7.1  LESSEE'S OBLIGATIONS.

         (a)  IN GENERAL. Subject to the provisions of Paragraph 2.2
(Condition), 2.3 (Compliance), 6.3 (Lessee's Compliance with Applicable
Requirements), 7.2 (Lessor's Obligations), 9 (Damage or Destruction), and 14
(Condemnation), Lessee shall, at Lessee's sole expense, keep the Premises,
Utility Installations (intended for Lessee's exclusive use, no matter where
located), and Alterations in good order, condition and repair (whether or not
the portion of the Premises requiring repairs, 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, but not
limited to, all equipment or facilities, such as plumbing, HVAC equipment,
electrical, lighting facilities, boilers, pressure vessels, 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. Lessee, in keeping the Premises in good
order, condition and repair, shall exercise and perform good maintenance
practices, specifically including the procurement and maintenance of the
service contracts required by Paragraph 7.1(b) below. 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)  SERVICE CONTRACTS. Lessee shall, at Lessee's sole expense,
procure and maintain contracts, with copies to Lessor, in customary form and
substance for, and with contractors specializing and experienced in the
maintenance of the following equipment and improvements, if any, if and when
installed on the Premises: (i) HVAC equipment, (ii) boiler and pressure
vessels, (iii) clarifiers, and (iv) any other equipment, if reasonably required
by Lessor. However, Lessor reserves the right, upon notice to Lessee, to
procure and maintain any or all of such service contracts, and if Lessor so
elects, Lessee shall reimburse Lessor, upon demand, for the cost thereof.

         (c)  FAILURE TO PERFORM. If Lessee fails to perform Lessee's
obligations under this Paragraph 7.1, Lessor may enter upon the Premises after
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, and Lessee
shall promptly reimburse Lessor for the cost thereof.

         (d)  REPLACEMENT. Subject to Lessee's indemnification of Lessor as set
forth in Paragraph 8.7 below, and without relieving Lessee of liability
resulting from Lessee's failure to exercise and perform good maintenance
practices, if an item described in Paragraph 7.1(b) cannot be repaired other
than at a cost which is in excess of 50% of the cost of replacing such item,
then such item shall be replaced by Lessor, and the cost thereof shall be
prorated between the Parties and Lessee shall only be obligated to pay, each
month during the remainder of the term of this Lease, on the date on which Base
Rent is due, an amount equal to the product of multiplying the cost of such
replacement by a fraction, the numerator of which is one, and the denominator
of which is 144 (i.e. 1/144th of the cost per month). Lessee shall pay interest
on the unamortized balance at a rate that is commercially reasonable in the
judgment of Lessor's accountants. Lessee may, however, prepay its obligation at
any time.

    7.2  LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 2.2
(Condition), 2.3 (Compliance), 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 system,
Common Area fire alarm and/or smoke detection systems, 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 to the extent it is
inconsistent with the terms of this Lease.

    7.3  UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS. See Addendum 59

         (a) DEFINITIONS. The term "UTILITY INSTALLATIONS" refers to all floor
and window coverings, air lines, power panels, electrical distribution,
security and fire protection systems, communication systems, lighting fixtures,
HVAC equipment, plumbing, and fencing in or on the Premises. The term "TRADE
FIXTURES" shall mean Lessee's machinery and equipment that can be removed
without doing material damage to the Premises. The term "ALTERATIONS" shall
mean any modification of the improvements, other than Utility Installations or
Trade Fixtures, whether by addition or deletion. "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).

         (b)  CONSENT. Lessee shall not make any Alterations or Utility
Installations to 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 such consent but upon notice to Lessor, as
long as they are not visible from the outside, do not involve puncturing,
relocating or removing the roof or any existing walls, and the cumulative cost
thereof during this Lease as extended does not exceed a sum equal to 3 month's
Base Rent in the aggregate or a sum equal to one month's Base Rent in any one
year. Notwithstanding the foregoing, Lessee shall not make or permit any roof
penetrations and/or install anything on the roof without the prior written
approval of Lessor. Lessor may, as a precondition to granting such approval,
require Lessee to utilize a contractor chosen and/or approved by Lessor. 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. Consent shall be deemed conditioned upon Lessee's: (i)
acquiring all applicable governmental permits, (ii) furnishing Lessor with
copies of both the permits and the plans and specifications prior to
commencement of the work, and (iii) compliance with all conditions of said
permits and other Applicable Requirements in a prompt and expeditious manner.
Any Alterations or Utility Installations shall be performed in a workmanlike
manner with good and sufficient materials. Lessee shall promptly upon completion
furnish Lessor with as-built plans and specifications. For work which costs an
amount in excess of one month's Base Rent, Lessor may condition its consent upon
Lessee providing a lien and completion bond in an amount equal to 150% of the
estimated cost of such Alteration or Utility Installation and/or upon Lessee's
posting an additional Security Deposit with Lessor.

         (c)  INDEMNIFICATION. 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 materialman's lien against the Premises or any interest therein. Lessee
shall give Lessor not less than 10 days' notice prior to the commencement of any

                                     PAGE 5
<PAGE>   6
work in, on or about the Premises, and Lessor shall have the right to post
notices of non-responsibility. If Lessee shall 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. If Lessor shall require, Lessee shall furnish a surety bond in an
amount equal to 150% of the amount of such contested lien, claim or demand,
indemnifying Lessor against liability for the same. If Lessor elects to
participate in any such action, Lessee shall pay Lessor's attorneys' fees and
costs.

     7.4  OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

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

          (b)  REMOVAL. By delivery to Lessee of written notice from Lessor not
earlier than 90 and not later than 30 days prior to the end of the term of this
Lease, Lessor may require that any or all Lessee Owned Alterations or Utility
Installations be removed by the expiration or termination of this Lease. Lessor
may require the removal at any time of all or any part of any Lessee Owned
Alterations or Utility Installations made without the required consent.

          (c)  SURRENDER; RESTORATION. Lessee shall surrender the Premises by
the Expiration Date or any earlier termination date, with all of the
improvements, parts and surfaces thereof broom 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. Notwithstanding the
foregoing, if this Lease is for 12 months or less, then Lessee shall surrender
the Premises in the same condition as delivered to Lessee on the Start Date with
NO allowance for ordinary wear and tear. Lessee shall repair any damage
occasioned by the installation, maintenance or removal of Trade Fixtures, Lessee
owned Alterations and/or Utility Installations, furnishings, and equipment as
well as the removal of any storage tank installed by or for Lessee. Lessee
shall also completely remove from the Premises any and all Hazardous Substances
brought onto the Premises by or for Lessee, or any third party (except Hazardous
Substances which were deposited via underground migration from areas outside of
the Project) even if such removal would require Lessee to perform or pay for
work that exceeds statutory requirements. Trade Fixtures shall remain the
property of Lessee and shall be removed by Lessee. The failure by Lessee to
timely vacate the Premises pursuant to this Paragraph 7.4(c) without the express
written consent of Lessor shall constitute a holdover under the provisions of
Paragraph 26 below.

8.   INSURANCE; INDEMNITY.

     8.1  PAYMENT OF PREMIUMS. The cost of the premiums for the insurance
policies required to be carried by Lessor, pursuant to Paragraphs 8.2(b), 8.3(a)
and 8.3(b), shall be a Common Area Operating Expense. Premiums for policy
periods commencing prior to, or extending beyond, the term of this Lease shall
be prorated to coincide with the corresponding Start Date or Expiration Date.

     8.2  LIABILITY INSURANCE.

          (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force a
Commercial General Liability policy of insurance and a policy of Worker's
Compensation insurance protecting Lessee and Lessor as an additional insured
against claims for bodily injury, personal injury and property damage based upon
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 annual aggregate of not less than $2,000,000, 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 shall not, however, limit the liability of Lessee nor relieve
Lessee of any obligation hereunder. All insurance 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. Copies of all such
policies shall be given to Lessor within ten (10) days after occupancy of the
Premises by Lessee.

          (b)  CARRIED BY LESSOR. Lessor shall maintain liability insurance as
described in Paragraph 8.2(a), in addition to, and 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
a policy or policies of insurance in the name of Lessor, with loss payable to
Lessor, any ground-lessor, and to any Lender insuring loss or damage to the
Premises. The amount of such insurance shall be equal to the full replacement
cost of the premises, as the same shall exist from time to time, or the amount
required by any Lender, but in no event more than the commercially reasonable
and available insurable value thereof. Lessee Owned Alterations and Utility
Installations, Trade Fixtures, and Lessee's personal property shall be insured
by Lessee under Paragraph 8.4. If the coverage is available and commercially
appropriate, such policy or policies shall insure against all risks of direct
physical loss or damage including coverage for debris removal and the
enforcement of any Applicable Requirements requiring the upgrading, demolition,
reconstruction or replacement of any portion of the Premises as the result of a
covered loss. Said policy or policies shall also contain an agreed valuation
provision in lieu of any coinsurance 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. If such insurance coverage has a deductible clause,
the deductible amount shall not exceed $1,000 per occurrence.

          (b)  RENTAL VALUE. Lessor shall also obtain and keep in force a policy
or policies in the name of Lessor with loss payable to Lessor and any Lender,
insuring the loss of the full Rent for one year with an extended period of
indemnity for an additional 180 days ("Rental Value insurance"). Said insurance
shall contain an agreed valuation provision in lieu of any coinsurance clause,
and the amount of coverable shall be adjusted annually to reflect the projected
Rent otherwise payable by Lessee, for the next 12 month period.

          (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 Project 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; BUSINESS INTERRUPTION INSURANCE.

          (a)  PROPERTY DAMAGE. Lessee shall obtain and maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee Owned
Alterations and Utility Installations. Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $1,000 per occurrence. The
proceeds from any such insurance shall be used by Lessee for the replacement of
personal property, Trade Fixtures and Lessee Owned Alterations and utility
Installations. Lessee shall provide Lessor with written evidence that such
insurance is in force.

          (b)  BUSINESS INTERRUPTION. Lessee shall obtain and maintain loss of
income and extra expense insurance in amounts as will reimburse Lessee for
direct or indirect loss of earnings attributable to all perils commonly insured
against by prudent lessees in the business of Lessee or attributable to
prevention of access to the Premises as a result of such perils.

          (c)  NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no
representation that the limits or forms of coverage of insurance specified
herein are adequate to cover Lessee's property, business operations or
obligations under this Lease.

     8.5  INSURANCE POLICIES. Insurance required herein shall be by companies
duly licensed or admitted to transact business in the state where the Premises
are located, and maintaining during the policy term a "General Policyholders
Rating" of at least B+, V, as set forth in the most current issue of "Best's
Insurance Guide", or such other rating as may be required by a Lender. Lessee
shall not do or permit to be done anything which invalidates the required
insurance policies. Lessee shall, prior to the Start Date, deliver to Lessor
certified copies of policies of such insurance or certificates evidencing the
existence and amounts of the required insurance. No such

                                     PAGE 6

<PAGE>   7
policy shall be cancelable or subject to modification except after 30 days prior
written notice to Lessor. Lessee shall, at least 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. Such policies shall be for a term of at least one year, or
the length of the remaining term of this Lease, whichever is less. If either
Party shall fail to procure and maintain the insurance required to be carried by
it, the other Party may, but shall not be required to, procure and maintain the
same.

     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 against the other, for loss of or
damage to its property arising out of or incident to the perils required to be
insured against herein. The effect of such releases and waivers is not limited
by the amount of insurance carried or required, or by any deductibles
applicable hereto. The Parties agree to have their respective property damage
insurance carriers waive any right to subrogation that such companies may have
against Lessor or Lessee, as the case may be, so long as the insurance is not
invalidated thereby.

     8.7  INDEMNITY. Except for Lessor's gross negligence or willful
misconduct, 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,
liens, judgments, penalties, attorneys' and consultants' fees, expenses and/or
liabilities arising out of, involving, or in connection with, the use and/or
occupancy of the Premises by Lessee. If any action or proceeding is brought
against Lessor by reason of any of the foregoing matters, Lessee shall upon
notice 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 defended or 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, HVAC or lighting fixtures, or from any other cause,
whether the said injury or damage results from conditions arising upon the
Premises or upon other portions of the Building, or from other sources or
places. Lessor shall not be liable for any damages arising from any act or
neglect of any other tenant of Lessor nor from the failure of Lessor to enforce
the provisions of any other lease in the Project. 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 improvements on the Premises, other than Lessee Owned Alterations and
Utility Installations, which can reasonably be repaired in 3 months or less
from the date of the damage or destruction, and the cost thereof does not
exceed a sum equal to 6 month's Base Rent. Lessor shall notify Lessee in
writing within 30 days from the date of the damage or destruction as to whether
or not the damage is Partial or Total.

          (b)  "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction to
the improvements on the Premises, other than Lessee Owned Alterations and
Utility Installations and Trade Fixtures, which cannot reasonably be repaired in
3 months or less from the date of the damage or destruction and/or the cost
thereof exceeds a sum equal to 6 month's Base Rent. Lessor shall notify Lessee
in writing within 30 days from the date of the damage or destruction as to
whether or not the damage is Partial or Total.

          (c)  "INSURED LOSS" shall mean damage or destruction to improvements
on 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 Requirements, 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  PARTIAL DAMAGE - INSURED LOSS. If a 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; provided, however that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $5,000 or less, and, in such event, Lessor shall make any
applicable insurance proceeds available to Lessee on a reasonable basis for
that purpose. Notwithstanding the foregoing, if the required insurance was not
in force or the insurance proceeds are not sufficient to effect such repair,
the Insuring Party shall promptly contribute the shortage in proceeds as and
when required to complete said repairs. In the event, however, such shortage
was due to the fact that, by reason of the unique nature of the improvements,
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 10 days following receipt of written notice of such shortage and request
therefor. If Lessor receives said funds or adequate assurance thereof within
said 10 day period, the party responsible for making the repairs shall complete
them as soon as reasonably possible and this Lease shall remain in full force
and effect. If such funds or assurance are not received, Lessor may
nevertheless elect by written notice to Lessee within 10 days thereafter to:
(i) 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, or (ii) have this Lease terminate 30 days thereafter. Lessee
shall not be entitled to reimbursement of 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, notwithstanding that there may be
some insurance coverage, but the net proceeds of any such insurance shall be
made available for the repairs if made by either Party.

     9.3  PARTIAL DAMAGE - UNINSURED LOSS. If a 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),
Lessor may 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) terminate this Lease by giving written notice to Lessee within
30 days after receipt by Lessor of knowledge of the occurrence of such damage.
Such termination shall be effective 60 days following the date of such notice.
In the event Lessor elects to terminate this Lease, Lessee shall have the right
within 10 days after receipt of the termination notice to give written notice
to Lessor of Lessee's commitment to pay for the repair of such damage without
reimbursement from Lessor. Lessee shall provide Lessor with said funds or
satisfactory assurance thereof within 30 days after marking such commitment. 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 make the required commitment, this Lease
shall terminate as of the date specified in the termination notice.

     9.4  TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs, this Lease shall terminate 60 days following
such Destruction. If the damage or destruction was caused by the gross
negligence or willful misconduct of Lessee, Lessor shall have the right to
recover Lessor's damages from Lessee, except as provided in Paragraph 8.6.

     9.5  DAMAGE NEAR END OF TERM. If at any time during the last 6 months 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 terminate this Lease
effective 60 days following the date of occurrence of such damage by giving a
written termination notice to Lessee within 30 days after the date of
occurrence of such damage. Notwithstanding the foregoing, 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 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 commercially
reasonable expense, repair such damage as soon as

                                     PAGE 7
<PAGE>   8
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 on the date specified in the
termination notice and Lessee's option shall be extinguished.

     9.6  ABATEMENT OF RENT; LESSEE'S REMEDIES.

          (a)  ABATEMENT. In the event of Premises Partial Damage or Premises
Total Destruction or a Hazardous Substance Condition for which Lessee is not
responsible under this Lease, the Rent payable by Lessee for the period
required for the repair, remediation or restoration of such damage shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired, but not to exceed the proceeds received from the Rental Value
Insurance. All other obligations of Lessee hereunder shall be performed by
Lessee, and Lessor shall have no liability for any such damage, destruction,
remediation, repair or restoration except as provided herein.

          (b)  REMEDIES. If Lessor shall be obligated to repair or restore the
Premises and does not commence, in a substantial and meaningful way, such
repair or restoration within 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 60 days
following the giving of such notice. If Lessee gives such notice and such
repair or restoration is not commenced within 30 days thereafter, this Lease
shall terminate as of the date specified in said notice. If the repair or
restoration is commenced within such 30 days, this Lease shall continue in full
force and effect. "Commence" shall mean either the unconditional authorization
of the preparation of the required plans, or the beginning of the actual work
on the Premises, whichever first occurs.

     9.7  TERMINATION; ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to Paragraph 6.2(g) or Paragraph 9, an equitable adjustment shall be
made concerning advance Base Rent and any other advance payments made by Lessee
to Lessor. Lessor shall, in addition, return to Lessee so much of Lessee's
Security Deposit as has not been, or is not then required to be, used by Lessor.

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

10.  REAL PROPERTY TAXES. See Addendum 60.

     10.1 DEFINITION. As used herein, the term "REAL PROPERTY TAXES" shall
include any form of assessment; real estate, general, special, ordinary or
extraordinary, or rental levy or tax (other than inheritance, personal income
or estate taxes); improvement bond; and/or license fee imposed upon or levied
against any legal or equitable interest of Lessor in the Project, Lessor's
right to other income therefrom, and/or Lessor's business of leasing, by any
authority having the direct or indirect power to tax and where the funds are
generated with reference to the Project address and where the proceeds so
generated are to be applied by the city, county or other local taxing authority
of a jurisdiction within which the Project is located. 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 during the term of this
Lease, including but not limited to, a change in the ownership of the Project
or any portion thereof or a change in the improvements thereon. 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.

     10.2 PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes applicable
to the Project, 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.

     10.3 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 Project by
other lessees or by Lessor for the exclusive enjoyment of such other lessees.
Notwithstanding Paragraph 10.2 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 PERSONAL 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. 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 10 days after receipt of a
written statement setting forth the taxes applicable to Lessee's property.

11.  UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon. Notwithstanding the provisions of
Paragraph 4.2, if at any time in Lessor's sole judgment, Lessor determines that
Lessee is using a disproportionate amount of water, electricity or other
commonly metered utilities, or that Lessee is generating such a large volume of
trash as to require an increase in the size of the dumpster and/or an increase
in the number of times per month that the dumpster is emptied, then Lessor may
increase Lessee's Base Rent by an amount equal to such increased costs.

12.  ASSIGNMENT AND SUBLETTING. See Addendum 52.

     12.1 LESSOR'S CONSENT REQUIRED

          (a)  Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or encumber (collectively, "ASSIGN OR ASSIGNMENT") or sublet
all or any part of Lessee's interest in this Lease or in the Premises without
Lessor's prior written consent.

          (b)  A change in the control of Lessee shall constitute an assignment
requiring consent. The transfer, on a cumulative basis, of 25% or more of the
voting control of Lessee shall constitute a change in control for this purpose.

          (c)  The involvement of Lessee or its assets in any transaction, or
series of transactions (by way of merger, sale, acquisition, financing,
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 by an amount greater than 25%
of such Net Worth as it was represented at the time of the execution 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, whichever was or is greater, shall be considered an
assignment of this Lease to which Lessor may withhold its consent. "NET WORTH OF
LESSEE" shall mean the net worth of Lessee (excluding any guarantors)
established under generally accepted accounting principles.

          (d)  An assignment or subletting without consent shall, at Lessor's
option, be a Default curable after notice per Paragraph 13.1(c), or a
noncurable Breach without the necessity of any notice and grace period. If
Lessor elects to treat such unapproved assignment or subletting as a noncurable
Breach, Lessor may either: (i) terminate this Lease, or (ii) upon 30 days
written notice, increase the monthly Base Rent to 110% of the Base Rent then in
effect. 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 110% of the price previously in effect, and
(ii) all fixed and non-fixed rental adjustments scheduled during the remainder
of the Lease term shall be increased to 110% of the scheduled adjusted rent.

          (e)  Lessee's remedy for any breach of 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, no assignment or subletting
shall: (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

                                     PAGE 8

<PAGE>   9
hereunder, or (iii) after the primary liability of Lessee for the payment of
Rent or for the performance of any other obligations to be performed by Lessee.

          (b)  Lessor may accept 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 Rent or performance shall constitute a waiver or estoppel
of Lessor's right to exercise its remedies for Lessee's Default or Breach.

          (c)  Lessor's consent to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting.

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

          (e)  Each request for consent to any 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 fee of
$1,000 or 10% of the current monthly Base Rent applicable to the portion of the
Premises which is the subject of the proposed assignment or sublease, whichever
is greater, as consideration for Lessor's considering and processing said
request. Lessee agrees to provide Lessor with such other or additional
information and/or documentation as may be reasonably requested.

          (f)  Any Assignee of, or sublessee under, this Lease shall, by reason
of accepting such assignment or entering into such sublease, be deemed 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 to in writing.

          (g)  Lessor's consent to any assignment or subletting shall not
transfer to the assignee or sublessee any Option granted to the original Lessee
by this Lease unless such transfer is specifically consented to by Lessor in
writing. (See Paragraph 39.2)

    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 Rent payable on any sublease, and Lessor may collect such Rent
and apply same toward Lessee's obligations under this Lease; provided, however,
that until a Breach shall occur in the performance of Lessee's obligations,
Lessee may collect said Rent. Lessor shall not, by reason of the foregoing or
any assignment of such sublease, nor by reason of the collection of Rent, be
deemed liable to the sublessee for any failure of Lessee to perform and comply
with any of Lessee's obligations to such sublessee. 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 all Rent due and to become due under the
sublease. Sublessee shall rely upon any such notice from Lessor and shall pay
all Rents to Lessor without any obligation or right to inquire as to whether
such Breach exists, notwithstanding any claim from Lessee to the contrary.

          (b)  In the event of a Breach by Lessee, Lessor may, at its option,
require sublessee to attorn to Lessor, in which event Lessor shall undertake
the obligations of the sublessor under such sublease from the time of the
exercise of said option to the expiration of such sublease; provided, however,
Lessor shall not be liable for any prepaid rents or security deposit paid by
such sublessee to such sublessor or for any prior Defaults or Breaches of such
sublessor.

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

          (d)  No Sublessee 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. A "DEFAULT" is defined as a failure by the Lessee
to comply with or perform any of the terms, covenants, conditions or Rules and
Regulations under this Lease. A "BREACH" is defined as the occurrence of one or
more of the following Defaults, and the failure of Lessee to cure such Default
within any applicable grace period:

          (a)  The abandonment of the Premises; or the vacating of the Premises
without providing a commercially reasonable level of security, or where the
coverage of the property insurance described in Paragraph 8.3 is jeopardized as
a result thereof, or without providing reasonable assurances to minimize
potential vandalism.

          (b)  The failure of Lessee to make any payment of Rent or any
Security Deposit required to be made by Lessee hereunder, whether to Lessor or
to a third party, when due, to provide reasonable evidence of insurance or
surety bond, or to fulfill any obligation under this Lease which endangers or
threatens life or property, where such failure continues for a period of 3
business days following written notice to Lessee.

          (c)  The failure by Lessee to provide (i) reasonable written evidence
of compliance with Applicable Requirements, (ii) the service contracts, (iii)
the rescission of any unauthorized assignment or subletting, (iv) an Estoppel
Certificate, (v) a requested subordination, (vi) evidence concerning any
guaranty and/or Guarantor, (vii) any document requested under Paragraph 41
(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 10 days following written notice 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 2.9 hereof,
other than those described in subparagraphs 13.1(a), (b) or (c), above, where
such Default continues for a period of 30 days after written notice; provided,
however, that if the nature of Lessee's Default is such that more than 30 days
are reasonably required for its cure, then it shall not be deemed to be a
Breach if Lessee commences such cure within said 30 day period and thereafter
diligently prosecutes such cure to completion.

          (e)  The occurrence of any of the following events: (i) the making of
any general arrangement or assignment for the benefit of creditors; (ii)
becoming a "DEBTOR" as defined in 11 U.S.C. Section 101 or any successor
statute thereto (unless, in the case of a petition filed against Lessee, the
same is dismissed within 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 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 30 days; provided, however, in the event that any provision
of this subparagraph (e) is contrary to any applicable law, such provision
shall be of no force or effect, and not affect the validity of the remaining
provisions.

          (f)  The discovery that any financial statement of Lessee or of any
Guarantor given to Lessor 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 basis, and
Lessee's failure, within 60 days following written notice of any such event, to
provide written alternative assurance or security, which, when coupled with the
then existing resources of Lessee, equals or exceeds the combined financial
resources of Lessee and Guarantors that existed at the time of execution of
this Lease.

    13.2  REMEDIES.  If Lessee fails to perform any of its affirmative duties
or obligations, within 10 days after written notice (or in case of an emergency,
without notice), Lessor may, at its option, 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 upon receipt of 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 option, may require all future payments to be made by Lessee to
be by cashier's check. In the event of a Breach, Lessor may, with or without
further notice or demand, and without

                                     PAGE 9

<PAGE>   10
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such Breach:

          (a)  Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession to Lessor. In such event Lessor shall be
entitled to recover from Lessee: (i) 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 the District within which the Premises are located
at the time of award plus one percent. Efforts by Lessor to mitigate damages
caused by Lessee's Breach of this Lease shall not waive Lessor's right to
recover damages under Paragraph 12. If termination of this Lease is obtained
through the provisional remedy of unlawful detainer, Lessor shall have the
right to recover in such proceeding any 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. If a notice and grace period required under
Paragraph 13.1 was not previously given, a notice to pay rent or quit, or to
perform or quit given to Lessee under the unlawful detainer statute shall also
constitute the notice required by Paragraph 13.1. In such case, the applicable
grace period required by Paragraph 13.1 and the unlawful detainer statute shall
run concurrently, and the failure of Lessee to cure the Default within the
greater of the two 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 and recover
the Rent as it becomes due, in which event Lessee may sublet or assign, subject
only to reasonably limitations. Acts of maintenance, efforts to relet, and/or
the appointment of a receiver to protect the Lessor's interests, shall not
constitute a termination of the Lessee's right to possession.

          (c)  Pursue any other remedy now or hereafter available under the laws
or judicial decisions of the state wherein the Premises are located. 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.  Any agreement for free or abated rent or other
charges, 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. Upon Breach 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, 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 shall not be deemed a waiver by Lessor of the
provisions of this paragraph unless specifically so stated in writing by Lessor
at the time of such acceptance.

    13.4  LATE CHARGE.  Lessee hereby acknowledges that late payment by Lessee
of Rent 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 any Lender. Accordingly, if any
Rent shall not be received by Lessor within 5 days after such amount shall be
due, then, without any requirement for notice to Lessee, Lessee shall pay to
Lessor a one-time late charge equal to 10% of each such overdue amount or $100,
whichever is greater. The parties hereby agree that such late charge represents
a fair and reasonable estimate of the costs Lessor will incur by reason of such
late payment. 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 the exercise of any of the other rights and remedies
granted hereunder. In the event that a late charge is payable hereunder,
whether or not collected, for 3 consecutive installments of Base Rent, then
notwithstanding any provision of this Lease to the contrary, Base Rent shall,
at Lessor's option, become due and payable quarterly in advance.

    13.5  INTEREST.  Any monetary payment due Lessor hereunder, other than late
charges, not received by Lessor, when due as to scheduled payments (such as
Base Rent) or within 30 days following the date on which it was due for
non-scheduled payment, shall bear interest from the date when due, as to
scheduled payments, or the 31st day after it was due as to non-scheduled
payments. The interest ("INTEREST") charged shall be equal to the prime rate
reported in the Wall Street Journal as published closest prior to the date when
due plus 4%, but shall not exceed the maximum rate allowed by law. Interest is
payable in addition to the potential late charge provided for in Paragraph 13.4.

    13.6  BREACH BY LESSOR.

          (a)  NOTICE OF BREACH.  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, a
reasonable time shall in no event be less than 30 days after receipt by Lessor,
and any Lender whose name and address shall have been furnished 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 30 days are reasonably required for
its performance, then Lessor shall not be in breach if performance is commenced
within such 30 day period and thereafter diligently pursued to completion.

          (b)  PERFORMANCE BY LESSEE ON BEHALF OF LESSOR.  In the event that
neither Lessor nor Lender cures said breach within 30 days after receipt of
said notice, or if having commenced said cure they do not diligently pursue it
to completion, then Lessee may elect to cure said breach at Lessee's expense
and offset from Rent an amount equal to the greater of one month's Base Rent or
the Security Deposit, and to pay an excess of such expense under protest,
reserving Lessee's right to reimbursement from Lessor. Lessee shall document
the cost of said cure and supply said documentation to Lessor.

14.  CONDEMNATION.  If the Premises or any portion thereof are not taken under
the power of eminent domain or sold under the threat of the exercise of said
power (collectively "CONDEMNATION"), this Lease shall terminate as to the part
taken as of the date the condemning authority takes title or possession,
whichever first occurs. If more than 10% of the floor area of the Unit, or
more than 25% of Lessee's Reserved Parking Spaces, is taken by Condemnation,
Lessee may, at Lessee's option, to be exercised in writing within 10 days after
Lessor shall have given Lessee written notice of such taking (or in the absence
of such notice, within 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
proportion to the reduction in utility of the Premises caused by such
Condemnation. Condemnation awards and/or payments shall be the property of
Lessor, whether such award shall be made as compensation for diminution in
value of the leasehold, the value of the part taken, or for severance damages;
provided, however, that Lessee shall be entitled to any compensation for
Lessee's expenses, loss of business goodwill and/or Trade Fixtures, without
regard to whether or not this Lease is terminated pursuant to the provisions of
this Paragraph. All Alterations and Utility Installations made to the Premises
by Lessee, for purposes of Condemnation only, shall be considered the property
off the Lessee and Lessee shall be entitled to any and all compensation which is
payable therefor. In the event that this Lease is not terminated by reason of
the Condemnation, Lessor shall repair any damage to the Premises caused by such
Condemnation.

15.  BROKERAGE FEES.

     15.1  ADDITIONAL COMMISSION.  In addition to the payments owed pursuant to
Paragraph 1.10 above, and unless Lessor and the Brokers otherwise agree in
writing, Lessor agrees that: (a) if Lessee exercises any Option, (b) if Lessee
acquires from Lessor any rights to the Premises or other premises owned by
Lessor and located within the Project; (c) if Lessee remains in possession of
the

                                    PAGE 10
<PAGE>   11

Premises, with the consent of Lessor, after the expiration of this Lease, or
(d) if Base Rent is increased, whether by agreement or operation of an
escalation clause herein, then, Lessor shall pay Brokers a fee in accordance
with the schedule of the Brokers in effect at the time of the execution of this
Lease.

      15.2  ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of Lessor's
interest in this Lease shall be deemed to have assumed Lessor's obligation
hereunder. Brokers shall be third party beneficiaries of the provisions of
Paragraphs 1.10, 15, 22 and 31. If Lessor fails to pay to Brokers any amounts
due as and for brokerage fees pertaining to this Lease when due, then such
amounts shall accrue interest. In addition, if Lessor fails to pay any amounts
to Lessee's Broker when due, Lessee's Broker may send written notice to Lessor
and Lessee of such failure and if Lessor fails to pay such amounts within 10
days after said notice, Lessee shall pay said monies to its Broker and offset
such amounts against Rent. In addition, Lessee's Broker shall be deemed to be a
third party beneficiary of any commission agreement entered into by and/or
between Lessor and Lessor's Broker for the limited purpose of collecting any
brokerage fee owned.

      15.3  REPRESENTATIONS AND INDEMNITIES OF BROKER RELATIONSHIPS. 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 the Brokers, if any) in
connection with this Lease, and that no one other than said named Brokers is
entitled to any commission or finder's fee in connection herewith. 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, attorneys' fees reasonably incurred with respect thereto.

16.   ESTOPPEL CERTIFICATES.

            (a)   Each Party (as "RESPONDING PARTY") shall within 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 form
similar to the then most current "ESTOPPEL CERTIFICATE" 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.

            (b)   If the Requesting Party shall fail to execute or deliver the
Estoppel Certificate within such 10 day period, the Requesting Party may
execute an Estoppel Certificate stating that: (i) the Lease is in full force
and effect without modification except as may be represented by the Requesting
Party, (ii) there are no uncured defaults in the Requesting Party's
performance, and (iii) if Lessor is the Requesting Party, not more than one
month's rent has been paid in advance. Prospective purchasers and encumbrances
may rely upon the Requesting Party's Estoppel Certificate, and the Responding
Party shall be estopped from denying the truth of the facts contained in said
Certificate.

            (c)   If Lessor desires to finance, refinance, or sell the
Premises, or any part thereof, Lessee and all Guarantors shall deliver to any
potential lender or purchaser designated by Lessor such financial statements as
may be reasonably required by such lender or purchaser, including but not
limited to Lessee's financial statements for the past 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.   DEFINITION OF LESSOR. The term "LESSOR" as used herein shall mean the
owner or owners at the time in question of the fee title to the Premises, or,
if this is a sublease, of the Lessee's interest in the prior lease. In the
event of a transfer of Lessor's title or interest in the Premises or this
Lease, Lessor shall deliver to the transferee or assignee (in cash or by
credit) any unused Security Deposit held by Lessor. Except as provided in
Paragraph 15, 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. Notwithstanding the above, and subject
to the provisions of Paragraph 20 below, the original Lessor under this Lease,
and all subsequent holders of the Lessor's interest in this Lease shall remain
liable and responsible with regard to the potential duties and liabilities of
Lessor pertaining to Hazardous Substances as outlined in Paragraph 6.2 above.

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.   DAYS. Unless otherwise specifically indicated to the contrary, the word
"DAYS" as used in this Lease shall mean and refer to calendar days.

20.   LIMITATION ON LIABILITY. Subject to the provisions of Paragraph 17 above,
the obligations of Lessor under this Lease shall not constitute personal
obligations of Lessor, the individual partners of Lessor or its or their
individual partners, directors, officers or shareholders, and Lessee shall look
to the Premises, and to no other assets of Lessor, for the satisfaction of any
liability of Lessor with respect to this Lease, and shall not seek recourse
against the individual partners of Lessor, or its or their individual partners,
directors, officers or shareholders, or any of their personal assets for such
satisfaction.

21.   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.

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 use, 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. The liability (including court costs
and attorneys' fees), of any Broker with respect to negotiation, execution,
delivery or performance by either Lessor or Lessee under this Lease or any
amendment or modification hereto shall be limited to an amount up to the fee
received by such Broker pursuant to this Lease; provided, however, that the
foregoing limitation on each Broker's liability shall not be applicable to any
gross negligence or willful misconduct of such Broker.

23.   NOTICES.

      23.1  NOTICE OF REQUIREMENTS. All notices required or permitted by this
Lease or applicable law shall be in writing and may be delivered in person (by
hand or by courier) or may be sent by regular, certified or registered mail or
U.S. Postal Service Express Mail, with postage prepaid, or by facsimile
transmission, 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
notices. Either Party may by written notice to the other specify a different
address for notice, except that upon Lessee's taking possession of the Premises,
the Premises shall constitute Lessee's address for notice. A copy of all notices
to Lessor shall be concurrently transmitted to such party or parties at such
addresses as Lessor may from time to time hereafter designate in writing.

     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 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 guarantee
next day delivery shall be deemed given 24 hours after delivery of the same to
the Postal Service or courier. Notices transmitted by facsimile transmission or
similar means shall be deemed delivered upon telephone confirmation of receipt
(confirmation report from fax machine is sufficient), provided a copy is also
delivered via delivery or mail. If notice is received on a Saturday, Sunday or
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 of any other term, covenant or condition hereof. Lessor's
consent to, or approval of, any 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. The acceptance of
Rent by Lessor shall not be a waiver of any Default or Breach by Lessee. Any
payment by Lessee may be accepted by Lessor on account of moneys or damages
due Lessor, notwithstanding any qualifying statements or conditions made by
Lessee in connection therewith, which such statements and/or conditions shall
be of no force or effect whatsoever unless specifically agreed to in writing by
Lessor at or before the time of deposit of

                                    PAGE 11

such payment.

25.   DISCLOSURE REGARDING THE NATURE OF A REAL ESTATE AGENCY RELATIONSHIP.

      (a)   When entering into a discussion with a real estate agent regarding a
real estate transaction, a Lessor or Lessee should from the outset understand
what type of agency relationship or representation it has with the agent or
agents in the transaction. Lessor and Lessee acknowledge being advised by the
Brokers in this transaction, as follows:

            (i)   Lessor's Agent. A Lessor's agent under a listing agreement
with the Lessor acts as the agent for the Lessor only. A Lessor's agent or
subagent has the following affirmative obligations: To the Lessor: A fiduciary
duty of utmost care, integrity, honesty, and loyalty in dealings with the
Lessor. To the Lessee and the Lessor: (a) Diligent exercise of reasonable skills
and care in performance of the agent's duties. (b) A duty of honest and fair
dealing and good faith. (c) A duly to disclose all facts known to the agent
materially affecting the value or desirability of the property that are not
known to, or within the diligent attention and observation of, the Parties. An
agent is not obligated to reveal to either Party any confidential information
obtained from the other Party which does not involve the affirmative duties set
forth above.

            (ii)  Lessee's Agent. An agent can agree to act as agent for the
Lessee only. In these situations, the agent is not the Lessor's agent, even if
by agreement the agent may receive compensation for services rendered, either
in full or in part from the Lessor. An agent acting only for a Lessee has the
following affirmative obligations. To the Lessee: A fiduciary duty of utmost
care, integrity, honesty, and loyalty in dealings with the Lessee. To the
Lessee and the Lessor: (a) Diligent exercise of reasonable skills and care in
performance of the agent's duties. (b) A duty of honest and fair dealing and
good faith. (c) A duty to disclose all facts known to the agent materially
affecting the value or desirability of the property that are not known to, or
within the diligent attention and observation of, the Parties. An agent is not
obligated to reveal to either Party any confidential information obtained from
the other Party which does not involve the affirmative duties set forth above.

            (iii) Agent Representing Both Lessor and Lessee. A real estate
agent, either acting directly or through one or more associate licenses, can
legally be the agent of both the Lessor and the Lessee in a transaction, but
only with the knowledge and consent of both the Lessor and the Lessee. In a
dual agency situation, the agent has the following affirmative obligations to
both the Lessor and the Lessee: (a) A fiduciary duty of utmost care, integrity,
honesty and loyalty in the dealings with either Lessor or the Lessee. (b) Other
duties to the Lessor and the Lessee as stated above in subparagraphs (i) or
(ii). In representing both lessor and Lessee, the agent may not without the
express permission of the respective Party, disclose to the other Party that
the Lessor will accept rent in an amount less than that indicated in the
listing or that the Lessee is willing to pay a higher rent than that offered.
The above duties of the agent in a real estate transaction do not relieve a
Lessor or Lessee from the responsibility to protect their own interests. Lessor
and Lessee should carefully read all agreements to assure that they adequately
express their understanding of the transaction. A real estate agent is a person
qualified to advise about real estate. Illegal or tax advice is desired,
consult a competent professional.

      (b)   Brokers have no responsibility with respect to any default or
breach hereof by either Party. The liability (including court costs and
attorneys' fees), of any Broker with respect to any breach of duty, error or
omission relating to this Lease shall not exceed the fee received by such
Broker pursuant to this Lease; provided, however, that the foregoing limitation
on each Broker's liability shall not be applicable to any gross negligence or
willful misconduct of such Broker.

      (c)   Buyer and Seller agree to identify to Brokers as "Confidential" any
communication or information given Brokers that is considered by such Party to
be confidential.

26.   NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or termination of this
Lease. In the event that Lessee holds over, then the Base Rent shall be
increased to 150% of the Base Rent applicable immediately preceding the
expiration or termination. Nothing contained herein shall be construed as
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; CONSTRUCTION OF AGREEMENT. All provisions of
this Lease to be observed or performed by Lessee are both covenants and
conditions. In construing this Lease, all headings and titles are for the
convenience of the Parties only and shall not be considered a part of this
Lease. Whenever required by the context, the singular shall include the plural
and vice versa. This Lease shall not be construed as if prepared by one of the
Parties, but rather according to its fair meaning as a whole, as if both
Parties had prepared it.

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 upon the Premises, to any and all advances made on the security
thereof, and to all renewals, modifications, and extensions thereof. Lessee
agrees that the holders of any such Security Devices (in this Lease together
referred to as "LENDER") shall have no liability or obligation to perform any of
the obligations of Lessor under this Lease. Any Lender may elect to have this
Lease and/or any Option granted hereby superior to the lien of its Security
Device by giving written notice thereof to Lessee, whereupon 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. In the event that Lessor transfers title to the
Premises, or the Premises are acquired by another upon the foreclosure or
termination of a Security Device to which this Lease is subordinated (i) Lessee
shall, subject to the non-disturbance provisions of Paragraph 30.3, attorn to
such new owner, and upon request, enter into a new lease containing all of the
terms and provisions of this Lease, with such new owner  for the remainder of
the term hereof, or, at the election of such new owner, this Lease shall
automatically become a new Lease between Lessee and such new owner, upon all of
the terms and conditions hereof, for the remainder of the term hereof, and (ii)
Lessor shall thereafter be relieved of any further obligations hereunder and
such new owner shall assume all of Lessor's obligations hereunder, except that
such new owner shall not; (a) be liable for any act or omission of any prior
lessor or with respect to events occurring prior to acquisition of ownership;
(b) be subject to any offsets or defenses which Lessee might have against any
prior lessor, (c) be bound by prepayment of more than one month's rent, or (d)
be liable for the return of any security deposit paid to any prior lessor.

      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 a commercially reasonable non-disturbance
agreement (a "NON-DISTURBANCE AGREEMENT") from the Lender which Non-Disturbance
Agreement provides that Lessee's possession of the Premises, 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. Further, within 60 days after the execution of this Lease, Lessor
shall use its commercially reasonable efforts to obtain a Non-Disturbance
Agreement from the holder of any pre-existing Security Device which is secured
by the Premises. In the event that Lessor is unable to provide the
Non-Disturbance Agreement within said 60 days, then Lessee may, at Lessee's
option, directly contact Lender and attempt to negotiate for the execution and
delivery of a Non-Disturbance Agreement.

      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 safe, financing or refinancing of the Premises, Lessee and Lessor shall
execute such further writings as may be reasonably required to separately
document any subordination, attornment and/or Non-Disturbance Agreement
provided for herein.

31.   ATTORNEY'S FEES. If any Party or Broker brings an action or proceeding
involving the Premises whether founded in tort, contract or equity, or to
declare rights hereunder, the Prevailing Party (as hereafter defined) in any
such proceeding, action, or appeal thereon, shall be entitled to reasonable
attorney's 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

                                    PAGE 12

<PAGE>   13
the abandonment by the other Party or Broker of its claim or defense. The
attorneys' fees award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees
reasonably incurred. In addition, Lessor shall be entitled to attorneys' fees,
costs and expenses incurred in the 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 ($200 is a reasonable minimum per occurrence for such services and
consultation).

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 tenants, and making such
alterations, repairs, improvements or additions to the Premises as Lessor may
deem necessary. All such activities shall be without abatement of rent or
liability to Lessee. Lessor may at any time place on the Premises any ordinary
"FOR SALE" signs and Lessor may during the last 6 months of the term hereof
place on the Premises any ordinary "FOR LEASE" signs. Lessee may at any time
place on the Premises any ordinary "FOR SUBLEASE" sign.

33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted, any
auction upon the Premises without Lessor's prior written consent. Lessor shall
not be obligated to exercise any standard of reasonableness in determining
whether to permit an auction.

34.  SIGNS. Except for ordinary "For Sublease" signs which may be placed only
on the Premises, Lessee shall not place any sign upon the Project without
Lessor's prior written consent. All signs must comply with all Applicable
Requirements. See Addendum 54.

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, that Lessor may elect to continue any one
or all existing subtenancies. Lessor's failure within 10 days following any
such event to elect 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. Except 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, including but not limited to consents
to an assignment, a subletting or the presence or use of Hazardous Substance,
shall be paid by Lessee upon receipt of an invoice and supporting documentation
therefor. Lessor's consent to any act, assignment or subletting 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. The failure to specify herein any particular
condition to Lessor's consent shall not preclude the imposition 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. In the
event that either Party disagrees with any determination made by the other
hereunder and reasonably requests the reasons for such determination, the
determining party shall furnish its reasons in writing and in reasonable detail
within 10 business days following such request.

37.  GUARANTOR.

     37.1  EXECUTION. The Guarantors, if any, shall each execute a guaranty 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.

     37.2  DEFAULT. It shall constitute a Default of the Lessee if any
Guarantor fails or refuses, upon request to provide: (a) evidence of the
execution of the guaranty, including the authority of the party signing on
Guarantor's behalf to obligate Guarantor, and in the case of a corporate
Guarantor, a certified copy of a resolution of its board of directors
authorizing the making of such guaranty, (b) current financial statements, (c)
an Estoppel Certificate, or (d) written confirmation that the guaranty is still
in effect.

38.  QUIET POSSESSION. Subject to payment by Lessee of the Rent and 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 and
quiet enjoyment of the Premises during the term hereof.

39.  OPTIONS. If Lessee is granted an option, as defined below, then the
following provisions shall apply. See Addendum 55.

     39.1  DEFINITION. "OPTION" shall mean: (a) the right to extend the term of
or renew this Lease or to extend or renew any lease that Lessee has on other
property of Lessor; (b) the right of first refusal or first offer to lease
either the Premises or other property of Lessor; (c) the right to purchase or
the right of first refusal to purchase the Premises or other property of Lessor.

     39.2  OPTIONS PERSONAL TO ORIGINAL LESSEE. Any Option granted to Lessee in
this Lease is personal to the original Lessee, and cannot be assigned or
exercised by anyone other than said original Lessee and only while the original
Lessee is in full possession of the Premises and, if requested by Lessor, with
Lessee certifying that Lessee has no intention of thereafter assigning or
subletting of the Premises and, if requested by Lessor, with Lessee certifying
that Lessee has no intention of thereafter assigning or subletting.

     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 have been validly exercised.

     39.4  EFFECT OF DEFAULT ON OPTIONS.

           (a)  Lessee shall have no right to exercise an Option: (i) during
the period commencing with the giving of any notice of Default and continuing
until said Default is cured, (ii) during the period of time any Rent is unpaid
(without regard to whether notice thereof is given Lessee), (iii) during the
time Lessee is in Breach of this Lease, or (iv) in the event that Lessee has
been given 3 or more notices of separate Default, whether or not the Defaults
are cured, during the 12 month period immediately preceding the exercise of
the Option.

           (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)  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 prior to the commencement of the extended term, (i) Lessee fails
to pay Rent for a period of 30 days after such Rent becomes due (without any
necessity of Lessor to give notice thereof), (ii) Lessor gives to Lessee 3 or
more notices of separate Default during any 12 month period, whether or not the
Defaults are cured, or (iii) if Lessee commits a Breach of this Lease.

40.  SECURITY MEASURES. Lessee hereby acknowledges that the Rent 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.

41.  RESERVATIONS. Lessor reserves the right: (i) to grant, without the consent
or joinder of Lessee, such easements, rights and dedications that Lessor deems
necessary, (ii) to cause the recordation of parcel maps and restrictions, and
(iii) to create and/or install new utility raceways, so long as such easements,
rights, dedications, maps, restrictions, and utility raceways do not
unreasonably interfere with the use of the Premises by Lessee. Lessee agrees to
sign any documents reasonably requested by Lessor to effectuate such rights.

42.  PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the
provisions hereof, the Party against whom the obligation to pay the money is
asserted shall have the right to make payment "under protest" and such payment
shall not be regarded as a voluntary payment and there shall survive the right
on the part of said Party to institute suit for recovery of such sum. If it
shall be adjudged that there was no legal obligation on the part of said Party
to pay such sum or any part thereof, said Party shall be entitled to recover
such sum or so much thereof as it was not legally required to pay.

43.  AUTHORITY. If either Party hereto is a corporation, trust, limited
liability company, partnership, or similar entity, each individual executing
this Lease on behalf of such entity represents and warrants that he or she is
duly authorized to execute and deliver this Lease on its behalf. Each party
shall, within 30 days after request, deliver to the other party satisfactory
evidence of such authority.

44.  CONFLICT. Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions shall be controlled by the
typewritten or handwritten provisions.

45.  OFFER. Preparation of this Lease by either party or their agent and
submission of same to the other Party shall not be deemed an offer to lease to
the other Party. This Lease is not intended to be binding until executed and
delivered by all Parties hereto.

46.  AMENDMENTS. This Lease may be modified only in writing, signed by the
Parties in interest at the time of the modification. As

                                    PAGE 13

<PAGE>   14

long as they do not materially change Lessee's obligations hereunder, Lessee
agrees to make such reasonable non-monetary modifications to this Lease as may
be reasonably required by a Lender in connection with the obtaining of normal
financing or refinancing of the Premises.

47.  MULTIPLE PARTIES. If more than one person or entity is named herein as
either Lessor or Lessee, such multiple Parties shall have joint and several
responsibility to comply with the terms of this Lease.

48.  WAIVER OF JURY TRIAL. The Parties hereby waive their respective rights to
trial by jury in any action or proceeding involving the Property or arising out
of this Agreement.

49.  MEDIATION AND ARBITRATION OF DISPUTES. An Addendum requiring the Mediation

52.  ASSIGNMENT AND SUBLETTING. Notwithstanding anything to the contrary
     contained in Paragraph 12 ("Assignment and Subletting"), as a condition
     for granting its consent to any assignment, transfer, or subletting,
     Lessor shall require that (i) that the sublease shall not provide for
     subtenant to have an option to extend the term of the sublease or an
     option to expand the sublet space, and (ii) Lessee shall pay to Lessor, as
     Additional Rent, fifty per cent (50%) of all rents and/or additional
     consideration due Lessee from its assignees, transferees, or subtenants in
     excess of the Rent payable by Lessee to Lessor hereunder for the assigned,
     transferred and/or subleased space ("Excess Rent"); provided however, that
     prior to sharing any Excess Rent to Lessor, Lessee shall first be entitled
     to recover from such Excess Rent the amount of any reasonable leasing
     commissions, subtenant improvements, and attorney fees paid by Lessee.

53.  CONDITION OF PREMISES: Notwithstanding anything to the contrary contained

55.  OPTION TO RENEW:

     A.   Lessor hereby grants to Lessee one (1) option to extend the initial
          lease term for a period of five (5) years. Provided that no material
          default of Lessee has occurred and is continuing on the date it gives
          notice of exercise, Lessee may exercise each of said renewal option
          by written notice to Lessor at least one hundred eighty (180) days
          prior to the date that the Lease term would otherwise expire. In the
          event that Lessee does not exercise the option granted hereunder,
          Lessor with reasonable notification shall have the right to
          immediately commence showing the premises to prospective tenants.

     B.   Lessor hereby grants to Lessee one (1) OPTION (the "Extension Option)
          to extend the Term of this Lease with respect to the entire Premises
          for one (1) additional period of five (5) years (the "Option Term"),
          on the same terms, covenants and conditions as provided for in this
          Lease during the initial Term, except that: Monthly Base Rent shall
          be established based on one hundred percent (100%) of the "fair
          market rental rate" for the Premises for the Option Term as defined
          and determined in accordance with the provisions of this Paragraph 55
          below, the Term, as extended, shall be five (5) years for such
          Extension

<PAGE>   16
        Option and Lessee shall have no further options to extend unless
        otherwise agreed by Lessor in its sole and absolute discretion; and
        monthly rates per stall for parking privileges shall be established
        based on one hundred percent (100%) of the fair market rental rate for
        similar parking privileges in similar "class" office buildings in the
        Los Altos/Mountain View, California area, as determined in Lessor's
        reasonable discretion. Notwithstanding the fair market rental rate
        determined pursuant to the provisions of this Paragraph 40 below, in no
        event will Monthly Base Rent payable during the Option Term be less than
        the Monthly Base Rent payable during the last year of payable during the
        Option Term be less than the Monthly Base Rent payable during the last
        year of the immediately preceding Term.

C.      The Extension Option must be exercised, if at all, by written  notice
        ("Extension Notice") delivered by Lessee to Lessor no later than the
        date which is six (6) months prior to the expiration of the initial Term
        of this Lease.

D.      The term "fair market rental rate" as used in this Addendum shall mean
        the annual amount per rentable square foot or per parking space (by
        type), which as of the date of determination is projected for and
        throughout the Option Term commencing upon the beginning of the Option
        Term to be acceptable to a willing, non-equity Lessee (excluding
        sublease and assignment transactions), and a willing Lessor of a similar
        quality office building located in the Los Altos/Mountain View,
        California area ("Comparison Area"), in an arm's length transaction
        (what Lessor is accepting in then current transactions for the Building
        may be considered for purposes of determining rent for an Option Term),
        for space of comparable size or greater, comparable in quality and floor
        height as the leased area at issue taking into account items that
        professional real estate brokers customarily consider, including, but
        not limited to, rental rates, office space availability, Lessee size,
        tenant improvement allowances, operating expenses and allowance, parking
        charges, free rent, free parking and other lease concessions, if any,

        writing not later than thirty (30) days following Lessor's receipt of
        Lessee's Extension Notice. Lessee will have thirty (30) days to
        ("Lessee's Review Period") after receipt of Lessor's notice of the fair
        market rental rate within which to accept such fair market rental rate
        or to object thereto in writing. Lessee's failure to accept the fair
        market rental rate submitted by Lessor in writing Lessee's Review
        Period, then Lessor and Lessee will attempt in good faith to agree upon
        such fair market rental rate using their best good faith efforts. If
        Lessor and Lessee fail to reach agreement on such fair market rental
        rate within fifteen (15) days following the expiration of Lessee's
        Review Period (the "Outside Agreement Date"), then the Extension Option
        will be deemed void and of no further force and effect, unless within
        ten (10) days after the Outside Agreement Date, Lessee demands
        appraisal, in which event each party will prepare a fair market rental
        rate determination which will be submitted to appraisal in accordance
        with the provisions below. The determination may be based on whatever
        information each party deems relevant, including reports and/or
        information prepared by brokers or appraisers retained by each
        respective party.

F.      (i)     Lessor and Lessee shall each appoint one appraiser who shall by
        profession be a real estate broker who has been active over the five (5)
        year period ending on the date of such appointment in the leasing of
        office space in the Comparison Area. Each such appraiser will be
        appointed within thirty (30) days after the Outside Agreement Date.

        (ii)    The two (2) appraisers so appointed will within fifteen (15)
        days of the date of the appointment of the last appointed appraiser
        agree upon and appoint a third appraiser who shall be qualified under
        the same criteria set forth herein above for qualification of the
        initial two (2) appraisers.

        (iii)   Within thirty (30) days of the appointment of the third
        appraiser, the parties will submit to the appraisers, and exchange with
        one another, all reports, information, and documentation, which the
        parties believe, support their respective fair market rental rate
        determinations.

        (iv)    Not more than ten (10) days following submission and exchange by
        Lessor and Lessee of their supporting documentation, the parties will
        appear jointly before the appraisers to present their positions and to
        respond to questions from the appraisers.

        (v)     The three (3) appraisers shall within thirty (30) days of the
        appointment of the joint appearance of the parties reach a decision as
        to whether the parties shall use Lessor's or Lessee's submitted fair
        market rental rate for the Premises is the closest to the actual fair
        market rental rate for the Premises as determined by the appraisers,
        taking into account the requirements of Paragraphs (B) and (D) above.

        (vi)    The decision of the majority of the three (3) appraisers shall
        be binding upon Lessor and Lessee. The cost of each party's appraiser
        shall be the responsibility of the party

                               Page 2 of 4 Pages

<PAGE>   17
          selecting such appraiser, and the cost of the third appraiser (or
          arbitration, if necessary) shall be shared equally by Lessor and
          Lessee.

          (vii) If either Lessor or Lessee fails to appoint an appraiser within
          the time period in Paragraph (F)(i) herein above, the appraiser
          appointed by one of them shall reach a decision, notify Lessor and
          Lessee thereof and such appraiser's decision shall be binding upon
          Lessor and Lessee.

          (viii) If the two (2) appraisers fail to agree upon and appoint a
          third appraiser, both appraisers shall be dismissed and the matter to
          be decided shall be forthwith submitted to arbitration.

          (ix) In the event that the new Monthly Base Rent is not established
          prior to end of the initial Term of the Lease, the Monthly Base Rent
          immediately payable at the commencement of the Option Term shall be
          the Monthly Base Rent established by the Lessor for the Option Term
          pursuant to the foregoing. Notwithstanding the above, once the fair
          market rental is determined in accordance with this section, the
          parties shall settle any overpayment or underpayment on the next
          Monthly Base Rent payment date falling not less than thirty (30) days
          after such determination and shall enter into an amendment to this
          Lease confirming the terms of the determination.

     G.   Lessor and Lessee have agreed that during the Option Period, the
          annual increase in the rental rate (years 2-5) shall be four percent
          (4%).
