      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 and any payments based thereon are not subject to revision whether or
not the actual size is more or less.

      2.2 Condition. See Paragraph 2.5. 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

[ILLEGIBLE] sprinkler systems, roof, foundations, and/or bearing walls - see
Paragraph 7).

      2.3 Compliance. See Paragraph 2.5. 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 zoning is 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 if 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 without 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 if
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.

      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. The Lessee is the Lessee
and occupant of the Premises on the Start Date and this Paragraph 2.5 is
operable. See also Addendum Paragraphs 52, 53, 54, 55 and 56.

      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 remains 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;

      (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.

[ILLEGIBLE] 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"). See Addendum Paragraphs 50 and 51.

      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.

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, 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 a 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 Paragraph 55.

            (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 potential 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.

[ILLEGIBLE] 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 Lessee's original occupancy of the Premises (unless caused by
Lessee, its agents or employees) 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 Lessee's original occupancy of
such Premises or portions thereof or which are caused by the gross negligence or
willful misconduct of Lessor, its agents or employees, unless such remediation
measure is required as a result of Lessee's use (including "Alterations", as
defined in paragraph 7.3(a) below) of the Premises, under the Old Lease or this
Lease, 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 an amount equal to 12
times 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.
   See Addendum Paragraph 56.

      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 (ie. 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.

            (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

                                                               /s/ [ILLEGIBLE]

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 materialmen'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 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. See Addendum Paragraph
56.

            (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 Premium Increases.

            (a) As used herein, the term "Insurance Cost Increase" is defined as
any increase in the actual cost of the insurance applicable to the Building
and/or the Project and required to be carried by Lessor, pursuant to Paragraphs
8.2(b), 8.3(a) and 8.3(b), ("Required Insurance"), over and above the Base
Premium, as hereinafter defined, calculated on an annual basis. Insurance Cost
Increase shall include, but not be limited to, requirements of the holder of a
mortgage or deed of trust covering the Premises, Building and/or Project,
increased valuation of the Premises, Building and/or Project, and/or a general
premium rate increase. The term Insurance Cost Increase shall not, however,
include any premium increases resulting from the nature of the occupancy of any
other tenant of the Building. If the parties insert a dollar amount in Paragraph
1.9, such amount shall be considered the "Base Premium." The Base Premium shall
be the annual premium applicable to the 12 month period immediately preceding
the Start Date. If, however, the Project was not insured for the entirety of
such 12 month period, then the Base Premium shall be the lowest annual premium
reasonably obtainable for the Required Insurance as of the Start Date, assuming
the most nominal use possible of the Building. In no event, however, shall
Lessee be responsible for any portion of the premium cost attributable to
liability insurance coverage in excess of $2,000,000 procured under Paragraph
8.2(b).

            (b) Lessee shall pay any Insurance Cost Increase to Lessor pursuant
to Paragraph 4.2. 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 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.

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

      8.3 Property Insurance - Building, Improvements and Rental Value.

            (a) Building and Improvements. Lessor shall obtain and keep in force
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 (except the perils of flood and/or earthquake unless
required by a Lender), 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 coverage 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
premium 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

                                                               /s/ [ILLEGIBLE]

[ILLEGIBLE] 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 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 making 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 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.

                                                               /s/ [ILLEGIBLE]

      10.1 Definitions.

            (a) "Real Property Taxes." 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.

            (b) "Base Real Property Taxes." As used herein, the term "Base Real
Property Taxes" shall be the amount of Real Property Taxes, which are assessed
against the Premises, Building, Project or Common Areas in the calendar year
during which the Lease is executed. In calculating Real Property Taxes for any
calendar year, the Real Property Taxes for any real estate tax year shall be
included in the calculation of Real Property Taxes for such calendar year 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
increases in such amounts over the Base Real Property Taxes shall be included in
the calculation of Common Area Operating Expenses in accordance with the
provisions of Paragraph 4.2.

      10.3 Additional Improvements. Common Area Operating Expenses shall not
include Real Property Taxes specified in the tax assessor's record 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. See
Addendum Paragraph 56.

12. Assignment and Subletting.

      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, any assignment or subletting
shall not: (i) be effective without the express written assumption by such
assignee or sublessee of the obligations of Lessee under this Lease, (ii)
release Lessee of any obligations hereunder, or (iii) alter 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 an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a 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.

      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

                                                               /s/ [ILLEGIBLE]

<PAGE>


[ILLEGIBLE]

            (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) service contracts, (iii) the
rescission of an 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. ss. 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 the 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 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 reasonable 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 Charges. 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 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

                                                               /s/ [ILLEGIBLE]

[ILLEGIBLE] to any compensation for Lessee's relocation 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 of 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.

      15.3 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 Responding 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 encumbrancers 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 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 monies or damages due Lessor,
notwithstanding any qualifying statements or conditions made by Lessee in
connection therewith, which such statements and/or conditions shall be of no
force or effect whatsoever unless specifically agreed to in writing by Lessor at
or before the time of deposit of such payment.

25. Disclosures 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

                                                               /s/ [ILLEGIBLE]
---------------                                                -----------------
/s/ [ILLEGIBLE]                                                /s/ [ILLEGIBLE]
---------------                                                -----------------
   Initials                                                         Initials


                                  Page 9 of 12
(C) 1998 - American Industrial Real Estate Association REVISED FORM MTG-2-11/98E


<PAGE>


[ILLEGIBLE] 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 any 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. If legal 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. Subject to the non-disturbance provisions of Paragraph
30.3; Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new 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 sale,
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. Attorneys' Fees. If any Party 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 attorneys' fees. Such
fees may be awarded in the same suit or recovered in a separate suit, whether or
not such action or proceeding is pursued to decision or judgment. The term,
"Prevailing Party" shall include, without limitation, a Party who substantially
obtains or defeats the relief sought, as the case may be, whether by compromise,
settlement, judgment, or the abandonment by the other Party of its claim or
defense. The attorneys' 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.

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 a 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

                                                               /s/ [ILLEGIBLE]

<PAGE>


[ILLEGIBLE] 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

quiet enjoyment of the Premises during the term hereof.

39. Options. If Lessee is granted an option, as defined below, then the

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.

      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

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

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

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

sign any documents reasonably requested by Lessor to effectuate such rights.

amount or sum of money to be paid by one Party to the other under the provisions

52.   Lessee's Occupancy and Obligations Prior to Start Date. Lessee is
      currently the Lessee and the sole occupant of the Premises pursuant to a
      Lease dated August 1, 1994, as amended ("Old Lease"). For the benefit of
      Lessor, Lessee acknowledges its obligations under the Old Lease,
      including, without limitation, Lessee's obligations with respect to the
      condition of the Premises at the end of the term of the Old Lease.

53.   Lessee's Occupancy on the Start Date. Lessor and Lessee acknowledge
      Lessee's occupancy of the Premises on and as of the Start Date. Lessor
      shall be deemed to have delivered the Premises to Lessee as of the Start
      Date "as is, where is" in the condition of the Premises on that date
      subject to Lessee's obligations to Lessor under the Old Lease. Lessor and
      Lessee further acknowledge that Paragraph 2.5, Lessee as Prior
      Owner/Occupant, of this Lease is applicable and reflects the agreement of
      the Parties.

54.   Termination of the Old Lease. Subject to any continuing obligations of
      Lessee under the Old Lease as set forth in Paragraphs 52 and 53 above, the
      Old Lease and Lessee's occupancy thereunder shall be deemed to have been
      terminated on September 30, 2001, and the provisions of this Lease shall
      govern Lessee's Lease and occupancy of the Premises from and after
      October 1, 2001.

55.   Hazardous Substances/Disclosure Certificate. Lessee acknowledges its
      obligations under Paragraph 6.2 of the Lease and affirms that Lessee's
      Reportable Use of Hazardous Substances under the Lease has and will at all
      times be done with timely compliance (at Lessee's expense) with all
      Applicable Requirements as more fully contemplated by Paragraph 6.2 of the
      Lease. In accordance with and as contemplated by Paragraph 6.2(b) of this
      Lease and not by way of limitation, Lessee shall promptly notify Lessor in
      writing and provide Lessor copies of any comments, notices or reports
      concerning Lessee's use of Hazardous Substances received by Lessee from or
      by any governmental agency. Prior to executing this Lease, Lessee has
      completed, executed and delivered to Lessor Lessee's initial Hazardous
      Substances Disclosure Certificate ("Initial HazMat Certificate") a copy of
      which is attached hereto as Exhibit C and incorporated herein by this
      reference. Lessee covenants, represents and warrants to Lessor that the
      information on the Initial HazMat Certificate is true and correct and
      accurately describes the use(s) of Hazardous Substances which are and/or
      will be made and/or used on the Premises by Lessee. Lessee shall
      commencing with the date which is one year from the Commencement Date and
      continuing every year thereafter or at any other time upon reasonable
      request of Lessor, complete, execute, and deliver to Lessor, a Hazardous
      Substances Disclosure Certificate (the "HazMat Certificate") substantially
      in the form of Exhibit C describing Lessee's then present use of Hazardous
      Substances on the Premises, and any other reasonably necessary documents
      as required by Lessor.

56.   Lessee's Alterations. Lessor and Lessee acknowledge that Lessee has
      substantially altered the Premises, especially the ground floor thereof
      since the Premises were delivered by Lessor to Lessee under the Old Lease.
      Such alterations included, without limitation, clean rooms, additional
      HVAC, office improvements, corridors and the like (collectively "Lessee's
      Alterations"). Such Lessee's Alterations are deemed to be "Lessee Owned
      Alterations and/or Utility Installations" under Paragraph 7 of this Lease.
      In the event that Lessor elects to require removal of the Lessee's
      Alterations or any portion thereof pursuant to Lessor's right to do so
      under Paragraph 7.4 of this Lease, Lessee shall restore the affected
      Premises to its condition as of the Commencement Date of the Old Lease,
      normal wear and tear excepted. The floor plans of the first and second
      floors of the Premises attached hereto as Exhibits B-2 and B-3
      respectively reflect generally the layout of the Premises on the
      Commencement Date of the Old Lease.

57.   Exterior Storage. Lessee shall neither store nor permit to be stored any
      vehicles, boats, RVs, goods, machinery, merchandise, equipment or any
      other items whatsoever on the Premises other than wholly within a closed
      building without the prior written approval of the Lessor. Any item left
      unattended for 96 hours is subject to removal at owner's expense.

      Mesa for their given space.
