3.    Incorporation By Reference.

      To the extent not inconsistent with the provisions of this Sub-Sublease,
the terms, provisions, covenants, and conditions of the Prime Lease are hereby
incorporated by reference on the following basis: The term "Landlord" therein
shall refer to Sub-Sublandlord hereunder, its successors and assigns; and the
term "Tenant" therein shall refer to Sub-Subtenant hereunder, its permitted
successors and assigns and in this Sub-Sublease Sub-Subtenant hereby assumes all
of the obligations and is granted and assigned on the terms set forth in this
Sub-Sublease all of the rights and interests of Sublandlord under the Prime
Lease with respect to the Premises accruing during the

                                       2
<PAGE>
Term and in this Sub-Sublease Sub-Sublandlord is granted and assigned all of the
rights (but does not assume the obligations) of Landlord under the Prime Lease
with respect to the Premises accruing during the Term. Anything to the contrary
herein notwithstanding, Sub-Subtenant is not assuming any obligation to pay Base
Rent or Additional Rent directly to Landlord. The rights and obligations assumed
by Sub-Subtenant and rights granted and assigned to Sub-Sublandlord hereunder
which accrue during the Term shall survive and extend beyond the termination of
this Sub-Sublease.

4.    Rent.

      (a) Sub-Subtenant shall, pay to Sub-Sublandlord, at its office referred to
above, as annual base rent (the "Base Rent") TWO HUNDRED TWO THOUSAND THREE
HUNDRED AND 00/100 DOLLARS ($202,300.00), which amount shall be due from and
after the Commencement Date and payable in advance in equal monthly installments
of $16,858.33 on the first (1st) day of each month, commencing on the
Commencement Date (except to the extent Base Rent has been prepaid pursuant to
Section 4(b) below).

      (b) An amount equal to one monthly installment of Base Rent has been paid
upon Sub-Subtenant's execution hereof, which sum shall be applied to the first
installment(s) of Base Rent due hereunder. If the Commencement Date is not the
first day of a month, the sum due for the calendar month in which the
Commencement Date occurs shall be prorated based on the number of days remaining
in said month after the Commencement Date. The balance of the sum remitted on
execution hereof, after application to the above-mentioned prorated sum, shall
be applied against the first full month's Base Rent due hereunder. All other
payments owed by Sub-Subtenant hereunder shall be paid as Additional Rent. Base
Rent and Additional Rent are herein collectively called "Rent".

      (c) Rent shall be paid without deduction or setoff, and Base Rent shall be
paid without notice or demand. If any Rent shall not be paid on or before the
due date thereof, Sub-Subtenant shall, in addition thereto, pay a late charge of
5% of the overdue installment.

5.    Escalations and Electrical Charges.

      (a) Pursuant to Section IV(A) of the Prime Lease, Sublandlord is obligated
to pay its Pro Rata Share of the amount, if any, by which Taxes for the
applicable calendar year exceed Taxes for the Base Year. Sub-Subtenant shall pay
to Sub-Sublandlord Sub-Subtenant's Pro Rata Share of the amount, if any, by
which Taxes for the applicable calendar year exceed Taxes for the Sub-Subtenant
Base Year. Notwithstanding the definition of Base Year in the Prime Lease, as
used in this Sub-Sublease, "Sub-Subtenant Base Year" shall be deemed to be the
calendar year ending December 31, 2001.

      (b) Pursuant to Section IV(A) of the Prime Lease, Sublandlord is obligated
to pay its Pro Rata Share of the amount, if any, by which Expenses for the

                                       3
<PAGE>
applicable calendar year exceed Expenses for the Base Year. Sub-Subtenant shall
pay to Sub-Sublandlord Sub-Subtenant's Pro Rata Share of the amount, if any, by
which Expenses for the applicable calendar year exceed Expenses for the
Sub-Subtenant Base Year.

      (c) Sub-Subtenant shall pay for all electrical services used at the
Premises in accordance with Section XI of the Prime Lease.

      (d) The amounts required to be paid by Sub-Subtenant to Sub-Sublandlord
under this Section shall be paid within ten (10) days after Sub-Sublandlord
shall render a statement therefor. Sub-Sublandlord's statement shall be
accompanied by copies of any relevant statements or bills received from Landlord
or Sublandlord. Sub-Subtenant shall make estimated payments to Sub-Sublandlord
of Sub-Subtenant's Pro Rata Share of Taxes and Expenses to the extent they
exceed the taxes and expenses during the Sub-Subtenant Base Year on the same
terms and conditions as Sub-Sublandlord is required to make similar estimated
payments under the terms of the Sublease or Sublandlord is required to make
similar estimated payments under the terms of the Prime Lease. If
Sub-Sublandlord receives any information regarding any audit by Sublandlord of
Landlord's actual Basic Costs pursuant to Section IV(c) of the Prime Lease,
Sub-Sublandlord will share such information with Sub-Subtenant.

6.    Subletting and Assignment.

      (a) Except as expressly set forth in Section 6(b) below, and
notwithstanding anything in the Prime Lease to the contrary, Sub-Subtenant shall
not, without the prior written consent of Sub-Sublandlord (which shall not be
unreasonably withheld for an assignment or sublease of this Sub-Sublease if the
net worth of the assignee or sublessee at the time of such transaction exceeds
the net worth of Sub-Subtenant on the date hereof), Sublandlord or Landlord; (a)
further sublet all or any part of the Premises; (b) transfer, hypothecate,
assign, convey, or mortgage this Sub-Sublease or any interest under it or allow
any lien upon Sub-Subtenant's interest hereunder by operation of law; or (c)
suffer, tolerate, permit, or allow the use or occupancy of the Premises by
anyone other than Sub-Subtenant; its agents and employees. No such transaction
shall release Sub-Subtenant from liability hereunder.

      (b) Anything herein to the contrary notwithstanding, but subject to any
contrary provisions in the Prime Lease and any requirement in the Prime Lease
that Landlord's consent be obtained and subject to any contrary provision in the
Sublease and any requirement in the Sublease that Sublandlord's consent be
obtained, Sub-Subtenant may, without Sub-Sublandlord's consent but following 30
days prior written notice to Sub-Sublandlord, assign this Sub-Sublease to (i)
any person or entity controlled by Sub-Subtenant, in control of Sub-Subtenant or
under common control with Sub-Subtenant, (ii) any surviving entity incident to a
merger,

                                       4

or substantially all of the assets of Sub-Subtenant, provided that in each case
the assignee has a net worth equal to or greater than Sub-Subtenant as of the
date of this Sub-Sublease. Additionally, an initial public offering of the stock
of Sub-Subtenant or any affiliate of Sub-Subtenant shall not be deemed an
assignment under this Sub-Sublease and the prior consent of the Sub-Sublandlord
thereto shall not be required. No such transaction shall release Sub-Subtenant
from liability hereunder.

7.    Insurance Compliance.

      (a) Sub-Subtenant shall maintain, at its sole cost and expense, for the
Term, general public liability insurance (naming Sub-Sublandlord, Sublandlord,
Landlord and designees of Landlord as additional insureds) against claims for
personal injury, death, or property damage occurring upon, in, about, or
adjacent to the Premises, such insurance to afford protection with combined
coverage of at least $2,000,000.00 with respect to personal injury, death and
property damage. Sub-Subtenant shall also maintain, at its sole expense, for the
Term, any and all insurance in the amounts and form required of Sub-Sublandlord
by and pursuant to the provisions of the Sublease with respect to the Premises
and Sublandlord by and pursuant to the provisions of the Prime Lease with
respect to the Premises. All such policies shall be issued by reputable
insurance companies approved by Landlord, Sublandlord and Sub-Sublandlord and
shall be endorsed to provide that they shall not be modified or canceled without
30 days' prior written notice to Sub-Sublandlord, Sublandlord and Landlord. On
or prior to the Commencement Date, Sub-Subtenant shall furnish to
Sub-Sublandlord Certificates of Insurance evidencing that the required coverage
is being maintained, together with such evidence as Sub-Sublandlord shall deem
satisfactory of the payment of premiums thereon.

8.    Indemnification.

      (a) Sub-Sublandlord, Sublandlord and Landlord, their officers, agents, and
employees, shall not be liable for, and Sub-Subtenant shall indemnify and save
Sub-Sublandlord, Sublandlord and Landlord harmless from and against all claims,
liability, loss, or damage during the Term to persons or property sustained by
Sub-Subtenant or by any other person, due to the Premises or any part thereof or
any appurtenances thereof becoming out of repair, or due to the happening of any
accident in, on, or about the Premises, or any damage caused by fire, or other
casualty or leakage, or due to the act or neglect of any person, excluding,
however, the gross negligence or willful misconduct of the employees, agents, or
contractors of the named indemnified parties and then only to the extent of such
gross negligence or willful misconduct of such party. This provision shall apply
(but not exclusively) to damage caused by sprinkling devices or air conditioning
or heating equipment and to damage caused by water, wind, frost, steam,
excessive heat or cold, broken

                                       5
<PAGE>
glass, gas, odors, or noise or by the bursting or leaking of pipes or plumbing
fixtures or the failure of any appurtenances or equipment. Sub-Sublandlord and
Sub-Subtenant waive all rights against each other for damages caused by fire or
other perils covered by insurance in connection with the Premises, to the extent
of insurance received.

      (b) Sub-Subtenant shall not take any action or fail to take any action in
connection with the Premises as a result of which Sub-Sublandlord would be in
violation of any of the provisions of the Sublease or Prime Lease or as a result
of which Sublandlord would be in violation of any of the provisions of the Prime
Lease; and Sub-Subtenant hereby agrees to defend, indemnify, and hold
Sub-Sublandlord and Sublandlord harmless from and against all loss, cost,
liability, damage, and expense (including, but not limited to, attorneys' fees
and court costs) caused by or arising out of Subtenant's breach of this
provision.

9.    Casualty.

      (a) If the Premises are damaged by fire or other casualty, and Landlord or
Sublandlord shall, pursuant to the terms of the Prime Lease, elect to terminate
the Prime Lease and if as a result the Sublease is terminated, this Sub-Sublease
shall cease and terminate on the date of termination of the Prime Lease and
Sublease, and Rent shall be apportioned from the time of the damage. Otherwise,
this Sub-Sublease shall remain in full force and effect, subject to the terms of
the Prime Lease and the Sublease. Sub-Sublandlord shall have no obligation
hereunder to repair any portion of the Premises, whether or not this
Sub-Sublease shall be terminated, which obligation shall be Landlord's to the
extent required under the Prime Lease. No provision of this Section 9 shall be
deemed to modify, amend or eliminate any right which Sub-Sublandlord has under
the Sublease.

10.   Rights of Landlord.

      (a) Sub-Subtenant acknowledges any rights specifically reserved by
Landlord under the Prime Lease or Sublandlord under the Sublease, and
Sub-Subtenant further acknowledges that its possession and use of the Premises
shall at all times be subject to such rights. Sub-Subtenant hereby releases
Sub-Sublandlord from all liability in connection with Landlord's and/or
Sublandlord's exercise of such rights provided that Landlord's and/or
Sublandlord's rights are not a result of a default by Sub-Sublandlord under the
terms of the Sublease or the Prime Lease.

      (b) If Sub-Subtenant fails to do any act required of it hereunder or under
the Prime Lease for five (5) days following written notice, Sub-Sublandlord may
(but shall not be obligated to) do so, and Sub-Subtenant shall pay the cost
thereof as Additional Rent within ten (10) days after receiving
Sub-Sublandlord's statement therefor. If Sub-Sublandlord fails to do any act
required of it hereunder,

                                       6
<PAGE>
Sub-Subtenant may provide written notice to Sub-Sublandlord of such failure and
if Sub-Sublandlord fails to do such act within ten (10) days following such
written notice, Subtenant may (but shall not be obligated to) do or perform such
act ten (10) days following such written notice to Sublandlord.

11.   Default by Landlord.

      Sub-Sublandlord shall not be liable to Sub-Subtenant for Landlord's
failure to perform any of Landlord's obligations under the Prime Lease or for
Sublandlord's failure to perform any of Sublandlord's obligations under the
Sublease, nor shall Sub-Sublandlord have any obligation to perform same or to
bring legal proceedings or take any other action against Landlord to assure
performance of Landlord's obligations under the Prime Lease or against
Sublandlord to assure performance of Sublandlord's obligations under the
Sublease nor shall the Landlord's failure to perform any of Landlord's
obligations under the Prime Lease or Sublandlord's failure to perform any of
Sublandlord's obligations under the Sublease affect Sub-Subtenant's duty to
fulfill its obligations under this Sub-Sublease, including without limitation,
the duty to pay Rent to Sub-Sublandlord hereunder. Except as otherwise provided
herein, whenever Sub-Sublandlord shall have the right to enforce any rights
against Landlord, Sublandlord or any other party under the Prime Lease or
Sublease because of the default or breach of Landlord, Sublandlord or such other
party with respect to the Premises, Sub-Sublandlord shall, at Sub-Subtenant's
expense paid in advance, give notice to Sublandlord requesting Sublandlord
enforce such right on behalf of itself, Sub-Sublandlord and Subtenant and if,
within a reasonable period after Sub-Subtenant's request, Sublandlord fails to
enforce such rights, then, provided Sub-Subtenant is not in default under this
Sub-Sublease, Sub-Subtenant shall have the right, in the name of Sub-Subtenant
or, if necessary, in the name of Sub-Sublandlord, to enforce any such rights of
Sub-Sublandlord with respect to the Premises. Such enforcement shall be at the
sole expense of Sub-Subtenant, and Sub-Subtenant shall indemnify Sub-Sublandlord
(and shall indemnify Sublandlord if such enforcement involves a proceeding
against Landlord by Sub-Subtenant) against all costs and expenses, including but
not limited to reasonable attorneys' fees, which may be incurred by
Sub-Sublandlord (and Sublandlord if proceedings against Landlord) in connection
with any claim, action, or proceeding so undertaken by Sub-Subtenant. Any amount
of recovery obtained by Sub-Subtenant shall be the property of Sub-Subtenant,
except that Sub-Sublandlord shall be compensated therefrom for any damages
sustained by Sub-Sublandlord as a consequence of such default or breach on the
part of Sublandlord, Landlord or such other party.

12.   Broker.

      (a) The parties acknowledge that this Sub-Sublease was procured through
the efforts of Ash Realty Brokerage, Inc. and Insignia/ESG Inc., and
Sub-Sublandlord shall compensate such brokers pursuant to separate agreement.

                                       7
<PAGE>
Sub-Subtenant represents and warrants that it dealt with no other broker in
connection with this Sub-Sublease and shall hold Sub-Sublandlord harmless from
any liability or loss, including reasonable attorneys' fees, arising from any
broker or salesman (other than as aforesaid) claiming a commission as a result
of having interested Sub-Subtenant in the Premises.

13.   Taxes.

      (a) Sub-Subtenant shall pay any taxes or fees imposed by any governmental
authority upon or as the result of this Sub-Sublease or the transfer of any
property or interests in property hereunder, except that Sub-Subtenant shall not
be liable for any federal, state, or municipal income tax imposed upon
Sub-Sublandlord as a result of this Sub-Sublease or any profits derived
hereunder.

14.   Remedies: Security Deposit.

      (a) The taking of any action by Sub-Subtenant, the occurrence of any event
in regard to Sub-Subtenant, or any failure to act by Sub-Subtenant which would
be a default under the Prime Lease if taken by Sublandlord or if occurring or
failing to occur in regard to Sublandlord, or which would be a default under the
Sublease if taken by Sub-Sublandlord or if occurring or failing to occur in
regard to Sub-Sublandlord, shall entitle Sub-Sublandlord to take all action with
regard to Sub-Subtenant under this Sub-Sublease which Landlord is permitted to
take against Sublandlord under the terms of the Prime Lease. To the extent that
Sublandlord is entitled to written notice and/or an opportunity to cure a
default under the Prime Lease prior to Landlord exercising any of its rights or
remedies under the Prime Lease, Sub-Subtenant shall be entitled to receive from
Sub-Sublandlord the same written notice and/or opportunity to cure said default
prior to the exercising by Sub-Sublandlord of any of its rights or remedies
under this Sub-Sublease except that the period after notice to cure non-monetary
defaults specified in Article XXII.B. shall be fifteen (15) days without
extension for any reason. The immediately preceding sentence shall not modify or
amend Landlord's rights or remedies under the Prime Lease. Sub-Subtenant hereby
indemnifies and holds Sub-Sublandlord harmless from and against all loss, cost,
injury, liability, or expense (including reasonable attorneys' fees and court
costs) caused by or arising out of Sub-Subtenant's default, breach, or violation
of the terms of this Sub-Sublease. So long as no event of default (or condition
which with the giving of notice or passage of time would constitute an event of
default) exists under this Sub-Sublease, Sub-Sublandlord shall indemnify and
hold Sub-Subtenant harmless from and against all actual loss, cost, injury,
liability or expense (specifically excluding, however, all consequential damages
and punitive damages) caused by or arising solely out of Sub-Sublandlord's
failure to pay Base Rent or Additional Rent in accordance with the Sublease.

                                       8
<PAGE>
      (b) Sub-Subtenant herewith deposits the sum of $33,716.66 (the "Deposit")
with Sub-Sublandlord as a security deposit to assure the faithful performance by
Sub-Subtenant of all of the obligations assumed by it hereunder, to be held and
applied pursuant to Section VI of the Prime Lease. Should part or all of the
Deposit be applied by Sub-Sublandlord for the payment of overdue Rent or other
obligations of Sub-Subtenant hereunder, then Sub-Subtenant shall, within 15 days
after the written demand of Sub-Sublandlord, remit to Sub-Sublandlord a
sufficient amount in cash to restore the Deposit to the original sum, and
Sub-Subtenant's failure to do so shall constitute a default hereunder. The
Deposit, to the extent not applied in accordance herewith, shall be returned to
Sub-Subtenant within thirty (30) days of the expiration of the Term. The Deposit
will be held by Sub-Sublandlord in a separate interest bearing account with
interest accruing for the benefit of Sub-Subtenant.

      (c) Sub-Subtenant acknowledges that the security deposit paid by
Sublandlord to Landlord pursuant to the terms of the Prime Lease is the property
of Sublandlord and that Sub-Subtenant has no claim or right to any portion of
such security deposit and that the security deposit paid by Sub-Sublandlord to
Sublandlord pursuant to the terms of the Sublease is the property of
Sub-Sublandlord and that Subtenant has no claim or right toy any portion of such
security deposit.

15.   Options.

      Anything in the Prime Lease or Sublease to the contrary notwithstanding,
Sub-Subtenant shall have no option to extend or renew the Term of this
Sub-Sublease or to expand the Premises.

16.   Surrender and Holdover.

      (a)   Upon any termination of this Sub-Sublease, by expiration of the
Term or otherwise:

            (i) Sub-Subtenant shall immediately vacate the Premises and
surrender possession thereof to Sub-Sublandlord in the condition required under
the Prime Lease as of the expiration date of the Prime Lease, provided, however,
Sub-Subtenant shall have no obligation to remove any Leasehold Improvements made
to the Premises prior to the date hereof;

            (ii)  Sub-Subtenant shall surrender the Premises free and clear
of all liens and encumbrances: and

            (iii) Sub-Sublandlord shall have full authority and license to enter
the Premises and take possession of same.

                                       9
<PAGE>
      (b) Sub-Subtenant shall pay to Sub-Sublandlord 200% of the monthly Rent
hereunder plus all other costs for each month or portion thereof that
Sub-Subtenant shall retain possession of the Premises or any part thereof after
the termination of this Sub-Sublease, whether by lapse of time or otherwise, and
shall also pay all damages sustained by Sub-Sublandlord to Sublandlord and by
Sublandlord to Landlord or otherwise on account thereof. Furthermore,
Sub-Subtenant shall be subject to eviction proceedings and any other remedy or
right accorded to Sub-Sublandlord in law or at equity. Any holding over by
Sub-Subtenant upon termination of this Sub-Sublease shall not be evidence of an
extension or renewal of the Term hereof, nor shall acceptance of Rent or other
payments by Sub-Sublandlord from Sub-Subtenant be evidence of the same, but
shall be on a month to month basis, terminable by either party on 30 days'
notice.

17.   Existing Furniture and Telephone System.

      Throughout the term of this Sub-Sublease, Sub-Subtenant shall have an
exclusive license to use all furniture and telephone systems currently located
in the Premises including, without limitation, all desks, partitioning, file
cabinets, chairs and all other furniture currently located in the Premises
(collectively, the "Furniture") and the telephone switch and telephone handsets
currently located in the Premises (collectively, the "Telephone System").

      Sub-Subtenant shall be responsible for maintaining the Furniture in good
order and repair, including all necessary repairs and replacements of same.
Sub-Subtenant shall also be responsible for maintaining the Telephone System in
good working order and repair, including all necessary repairs and replacements
of same and all necessary upgrades or changes required by Sub-Subtenant's use
thereof. Sub-Subtenant shall also be required to maintain a maintenance contract
on the Telephone System with Lucent Technologies or such other vendor as
Sub-Sublandlord and Sublandlord may approve in writing. In the event that
Sub-Subtenant fails to maintain the Furniture or the Telephone System in good
working order and repair or if Sub-Subtenant fails to maintain the required
maintenance contract for the Telephone System and such default continues more
than 10 days after notice from Sub-Sublandlord, Sub-Sublandlord or Sublandlord
shall be entitled to cause all such maintenance to the Furniture and/or the
Telephone System to be performed and Sub-Sublandlord or Sublandlord may maintain
such maintenance contract on the Telephone System and Sub-Subtenant shall
reimburse Sub-Sublandlord or Sublandlord for the reasonable cost thereof as
Additional Rent. Sub-Subtenant's failure to reimburse Sub-Sublandlord or
Sublandlord within 15 days after receipt of written demand by Sub-Sublandlord
shall constitute a default thereunder.

      Provided no event of default (or condition which with the giving of notice
or passage of time would constitute an event of default) exists hereunder, under
the Sublease or under the Prime Lease at the expiration of the Term,
Sub-Subtenant

                                       10
<PAGE>
shall have the option to purchase the Furniture and the Telephone System for the
sum of one dollar ($1.00) upon the expiration of the Term and, upon request of
Sub-Subtenant, Sub-Sublandlord shall execute and deliver an appropriate bill of
sale within twenty days of Sub-Subtenants request. Should an event of default
(or a condition which with the giving of notice or passage of time would
constitute an event of default) exist hereunder or under the Prime Lease at the
expiration of the Term of this Sub-Sublease, Sub-Sublandlord shall provide
Sub-Subtenant with written notice of such default and a period of 5 days (with
respect to a monetary default) and 10 days (with respect to a non-monetary
default) from the date of the notice to cure such default. In such event,
Sub-Sublandlord or Sublandlord, at Sub-Subtenant's sole cost and expense, may
remove the Furniture and Telephone System from the Premises and store it for the
benefit of Sub-Subtenant, in no event shall Sub-Sublandlord or Sublandlord be
liable for any damage to or destruction of said Furniture and/or Telephone
System. In the event that Sub-Subtenant cures such default within the applicable
cure period, Sub-Subtenant may then exercise its option to purchase the

the Furniture and Telephone System.

have no liability hereunder and no obligation to take action hereunder and
Sub-Subtenant's rights shall be as set forth in Section 11 hereof.

and conditions of this Sub-Sublease and the terms and conditions of the Prime

invalid or unenforceable for any reason, this Sub-Sublease shall be construed as
not containing such provision, and the invalidity or unenforceability thereof
shall not render any other provision of this Sub-Sublease invalid or
unenforceable.

      (d) Any provision of this Sub-Sublease or the Prime Lease which requires
Sub-Sublandlord not to unreasonably withhold its consent shall never be the
basis for an award of damages or give rise to a right of setoff to

      (e) Whenever Sub-Subtenant must obtain the consent of Landlord or
Sublandlord with respect to the Premises, Sub-Sublandlord shall cooperate fully

forward to Sub-Subtenant true copies of all notices, requests, demands and
communications received by Sub-Sublandlord from Landlord (or its agent) or
Sublandlord with respect to the Premises. If Sub-Subtenant shall not give timely

or Sublandlord as Sub-Sublandlord desires, or no notice or direction with
respect to the matter in question.

      (f) Sub-Subtenant shall indemnify and hold Sub-Sublandlord harmless from
the costs of any special services (including without limitation overtime HVAC
and special cleaning services) which Sub-Subtenant may order through
Sub-Sublandlord, Sublandlord or directly from Landlord with respect to the
Premises.

prepared and drafted; each party has been represented by legal counsel; and, in
connection with the construction of any provision hereof or deletion herefrom,
no consideration shall be given to the issue of which party actually prepared,
drafted, requested or negotiated any such provision or deletion.

19.   Landlord's and Sublandlord's Approval.

      Immediately following execution of this Sub-Sublease, Sub-Sublandlord
shall submit this Sub-Sublease to Sublandlord for Sublandlord's approval and
request that Sublandlord submit same to Landlord for Landlord's approval.
Thereafter both parties shall promptly comply with any request of Landlord or
Sublandlord for additional information or documentation and shall refrain from

such thirty (30) day period may elect to terminate this Sub-Sublease, whereupon
Sub-Sublandlord shall promptly refund any amounts deposited hereunder, and this
Sub-Sublease shall be of no further force and effect. The parties hereto shall
not bring any claim against each other for any loss, cost, expense, damage, or
injury caused by or arising out of the failure of Landlord or Sublandlord to
consent to this Sub-Sublease except where a party acts in bad faith to in
intentionally cause Landlord or Sublandlord to refuse its consent. Concurrently
with entering into this Sub-Sublease, Sub-Sublandlord is entering into a
Sublease (the "Plaut Sublease"), dated on or about the date hereof, between
Plaut Consulting, Inc., as sublessor, and Sub-Sublandlord, as sublessee, for
premises known as Suite 640, Three Westbrook Corporate Center, Westchester,
Illinois 60154. The effectiveness of the Plaut Sublease is conditioned upon
obtaining the consent of Landlord. Consequently, in the event the Landlord fails
to approve the Plaut Sublease within thirty (30) days of the date hereof.
Sub-Sublandlord upon notice to Sub-Subtenant within seven (7) days after the
expiration of such thirty (30) day period may elect to terminate this
Sub-Sublease, whereupon Sub-Sublandlord shall promptly refund any amounts
deposited hereunder, and this Sub-Sublease shall be of no further force and
effect. The parties hereto shall not bring any claim against each other for any
loss, cost, expense, damage, or injury caused by or arising out of the failure
of Landlord to consent to the Plaut Sublease.

loan obligation, any guaranty obligation or any other contract obligation to
which Sub-Subtenant is a party or

                                       13

business. Sub-Sublandlord may provide copies of the items set forth in (i) and

      Except with the prior written consent of Sub-Subtenant, Sub-Sublandlord
shall not (i) terminate, cancel or surrender the Sublease, either in accordance
with the terms of the Sublease or otherwise, except to the extent that
Sub-Sublandlord has the right to terminate the Sublease following a casualty or
condemnation in accordance with the terms and conditions of Section 9 of this
Sub-Sublease; (ii) modify, amend, or revise any term or provisions of the
Sublease, in any way which would materially and adversely affect Sub-Subtenant's
rights and obligations under this Sub-Sublease, or (iii) take or omit to take
any action which would constitute an event of default beyond any applicable
grace, notice and cure periods under the Sublease or Prime Lease or otherwise
entitle Sublandlord to terminate the Sublease or Landlord to terminate the Prime
Lease.

      IN WITNESS WHEREOF, the parties have executed this Sublease the day and
year first above written.

exist from time to time, subject to any rights, powers, and privileges reserved
by Lessor under the terms hereof or under the terms of any rules and
regulations or restrictions governing the use of the Industrial Center. Under
no circumstances shall the right herein granted to use the Common Areas be
deemed to include the right to store any property, temporarily or permanently,
in the Common Areas. Any such storage shall be permitted only by the prior
written consent of Lessor or Lessor's designated agent, which consent may be
revoked at any time. In the event that any unauthorized storage shall occur

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 an Early Possession Date is specified in
Paragraph 1.4 and if Lessee totally or partially occupies the Premises after
the Early Possession Date but prior to the Commencement Date, the obligation to
pay Base Rent shall be abated for the period of such early occupancy. All other
terms of this Lease, however, (including, but not limited to, the obligations
to pay Lessee's Share of Common Area Operating Expenses and to carry the
insurance required by Paragraph 8) shall be in effect during such period. Any
such early possession shall not affect nor advance the Expiration Date of the
Original Term.

     3.3  Delay in Possession. If for any reason Lessor cannot deliver
possession of the Premises to Lessee by the Early Possession Date, if one is
specified in Paragraph 1.4, or if no Early Possession Date is specified, by the
Commencement Date, Lessor shall not be subject to any liability therefor, nor
shall such failure affect the validity of this Lease, or the obligations of
Lessee hereunder, or extend the term hereof, but in such case, Lessee shall
not, except as otherwise provided herein, be obligated to pay rent or perform
any other obligation of Lessee under the terms of this Lease until Lessor
delivers possession of the Premises to Lessee. If possession of the Premises is
not delivered to Lessee within sixty (60) days after the Commencement Date,
Lessee may, at its option, by notice in writing to Lessor within ten (10) days
after the said sixty (60) day period, cancel this Lease, in which event the
Parties shall be discharged from all obligations hereunder; provided further,
however, that if such written notice of Lessee is not received by Lessor
within said ten (10) day period, Lessee's right to cancel this Lease
hereunder shall terminate and be of no further force or effect. Except as may
be otherwise provided, and regardless of when the Original Term actually
commences, if possession is not tendered to Lessee when required by this Lease
and Lessee does not terminate this Lease, as aforesaid, the period free of the
obligation to pay Base Rent, if any, that Lessee would otherwise have enjoyed
shall run from the date of delivery of possession and continue for a period
equal to the period during which the Lessee would have otherwise enjoyed under
the terms hereof, but minus any days of delay caused by the acts, changes or
omissions of Lessee.

4.   Rent.

     4.1  Base Rent. Lessee shall pay Base Rent and other rent or charges, as
the same may be adjusted from time to time, to Lessor in lawful money of the
United States, without offset or deduction, on or before the day on which it is
due under the terms of this Lease. Base Rent and all other rent and charges for
any period during the term hereof which is for less than one full month shall
be prorated based upon the actual number of days of the month involved. Payment
of Base Rent and other charges shall be made to Lessor at its address stated
herein or to such other persons or at such other addresses as Lessor may from
time to time designate in writing to Lessee.

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

          (a) "Common Area Operating Expenses" are defined, for purposes of
this Lease, as the following costs incurred by Lessor relating to the owner
operation of the Industrial Center:

security services and the costs of any environmental inspections.

          (v) Any increase above the Base Real Property Taxes (as defined in
Paragraph 10.2(b)) for the Building and the Common Areas.

          (vi) Any "Insurance Cost Increase" (as defined in Paragraph 8.1).

          (viii) Any deductible portion of an insured loss concerning the
Building.

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

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

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

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

6. USE.

     6.1 PERMITTED USE.

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

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

     6.2  HAZARDOUS SUBSTANCES.

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

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

     (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all damages, liabilities,
judgments, costs, claims, liens, expenses, penalties, loss of permits and
attorneys' and consultants' fees arising out of or involving any Hazardous
Substance brought onto the Premises by or for Lessee or by anyone under
Lessee's control. Lessee's obligations under this Paragraph 6.2(c) shall
include, but not be limited to, the effects of any contamination or injury to
person, property or the environment created or suffered by Lessee, and the
cost of investigation (including consultants' and attorneys' fees and testing),
removal, remediation, restoration and/or abatement thereof, or of any
contamination therein involved, and shall survive the expiration or earlier
termination of this Lease. No

termination, cancellation or release agreement entered into by Lessor and
Lessee shall release Lessee from its obligations under this Lease with respect
to Hazardous Substances, unless specifically so agreed by Lessor in writing at
the time of such agreement.

     6.3  Lessee's Compliance with Requirements. Lessee shall, at Lessee's sole
cost and expense, fully, diligently and in a timely manner, comply with all
"Applicable Requirements," which term is used in this Lease to mean all laws,
rules, regulations, ordinances, directives, covenants, easements and
restrictions of record, permits, the requirements of any applicable fire
insurance underwriter or rating bureau, and the recommendations of Lessor's
engineers and/or consultants, relating in any manner to the Premises (including,
but not limited to, matters pertaining to (i) industrial hygiene, (ii)
environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions, and (iii) the use, generation, manufacture, production,
installation, maintenance, removal, transportation, storage spill, or release
of any Hazardous Substance), now in effect or which may hereafter come into
effect. Lessee shall, within five (5) days after receipt of Lessor's written
request, provide Lessor with copies of all documents and information,
including, but not limited to, permits, registrations, manifests, applications,
reports and certificates, evidencing Lessee's compliance with any Applicable
Requirements specified by Lessor, and shall immediately upon receipt, notify
Lessor in writing (with copies of any documents involved) of any threatened or
actual claim, notice, citation, warning, complaint or report pertaining to or
involving failure by Lessee or the Premises to comply with any Applicable
Requirements.

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

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

     7.1  Lessee's Obligations.

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

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

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

     7.3  Utility Installations, Trade Fixtures, Alterations.

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

          (b)  Consent. Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with detailed plans. All consents given by
Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific consent,
shall be deemed conditioned upon: (i) Lessee's acquiring all applicable permits
required by governmental authorities; (ii) the furnishing of copies of such
permits together with a copy of the plans and specifications for the Alteration
or Utility Installation to Lessor prior to commencement of the work thereon; and
(iii) the compliance by Lessee with all conditions of said permits in a prompt
and expeditious manner. Any Alterations or Utility Installations by Lessee
during the term of this Lease shall be done in a good and workmanlike manner,
with good and sufficient materials, and be in compliance with all Applicable
Requirements. Lessee shall promptly upon completion thereof furnish Lessor with
as-built plans and specifications therefor. Lessor may (but without obligation
to do so) condition its consent to any requested Alteration or Utility
Installation that costs $10,000.00 or more upon Lessee's providing Lessor with a
lien and completion bond in an amount equal to one and one-half times the
estimated cost of such Alteration or Utility Installation.

          (c)  Lien Protection. Lessee shall pay when due all claims for labor
or materials furnished or alleged to have been furnished to or for Lessee at or
for use on the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, and Lessor shall have the right to post
notices of non-responsibility in or on the Premises as provided by law. If
Lessee shall, in good faith, contest the validity of any such lien, claim or
demand, then Lessee shall, at its sole expense, defend and protect itself,
Lessor and the Premises against the same and shall pay and satisfy any such
adverse judgment that may be rendered thereon before the enforcement thereof
against the Lessor or the Premises. If Lessor shall require, Lessee shall
furnish to Lessor a surety bond satisfactory to Lessor, in an amount equal to
one one-half times the amount of such contested lien claim or demand,
indemnifying Lessor against liability for the same, as required by law for the
holding of the Premises free from the effect of such lien or claim. In addition,
Lessor may require Lessee to pay Lessor's attorneys' fees and costs in
participating in such action if Lessor shall decide it is to its best interest
to do so.

     7.4  Ownership, Removal, Surrender, and Restoration.

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

      (b)  Removal.  Unless otherwise agreed in writing, Lessor may require that
any or all Lessee-Owned Alterations or Utility installations be removed by the
expiration or earlier termination of this Lease, notwithstanding that their
installation may have been consented to by Lessor. Lessor may require the
removal at any time of all or any part of any Alterations or Utility
Installations made without the required consent of Lessor.

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

8.  Insurance; Indemnity.

   8.1  Payment of Premium Increases.

      (a)  As used herein, the term "Insurance Cost Increase" is defined as any
increase in the actual cost of the insurance applicable to the Building and
required to be carried by Lessor pursuant to Paragraphs 8.2(b), 8.3(a),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, increased valuation of the Premises, and/or a general
premium rate increase. The term "Insurance Cost Increase" shall not, however,
include any premium increase resulting from the nature of the occupancy of any
other lessee of the Building. If the Parties insert a dollar amount in Paragraph
1.9, such amount shall be considered the "Base Premium." If a dollar amount has
not been inserted in Paragraph 1.9 and if the Building has been previously
occupied during the twelve (12) month period immediately preceding the
Commencement Date, the "Base Premium" shall be the annual premium applicable to
such twelve (12) month period. If the Building was not fully occupied during
such twelve (12) month period, the "Base Premium" shall be the lowest annual
premium reasonably obtainable for the Required Insurance as of the Commencement
Date, assuming the most nominal use possible of the Building. In no event,
however, shall Lessee be responsible for any portion of the premium cost
attributable to liability insurance coverage in excess of $1,000,000 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 Commencement Date of Expiration Date.

   8.2  Liability Insurance

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

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

   8.3  Property Insurance - Building, Improvements and Rental Value.

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

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

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

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

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

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

                                                                   Initials:  DG

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

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

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

9.   Damages or Destruction.

     9.1  Definitions.

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

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

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

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

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

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

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

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

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

     9.6  Abatement of Rent; Lessee's Remedies.

          (a) in the event of (i) Premises Partial Damage or (ii) Hazardous
Substance Condition for which Lessee is not legally responsible, the Base Rent,

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

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

     9.7  Hazardous Substance Conditions. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable
Requirements and this Lease shall continue in full force and effect, but subject
to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor may at
Lessor's option either (i) investigate and remediate such Hazardous Substance
Condition, if required, as soon as reasonably possible at Lessor's expense, in
which event this Lease shall continue in full force and effect, or (ii) if the
estimated cost to investigate and remediate such condition exceeds twelve (12)
times the then monthly Base Rent or $100,000, whichever is greater, give written
notice to Lessee within thirty (30) days after receipt by Lessor of knowledge of
the occurrence of such Hazardous Substance Condition of Lessor's desire to
terminate this Lease within sixty (60) days following the date of such notice.
In the event Lessor elects to give such notice of Lessor's intention to
terminate this Lease, Lessee shall have the right within ten (10) days after the
receipt of such notice to give written notice to Lessor of Lessee's commitment
to pay for the excess costs of (a) investigation and remediation of such
Hazardous Substance Condition to the extent required by Applicable Requirements,
over (b) an amount equal to twelve (12) times the then monthly Base Rent or
$100,000, whichever is greater. Lessees shall provide Lessor with the funds
required of Lessee or satisfactory assurance thereof within thirty (30) days
following said commitment by Lessee. In such event this Lease shall continue in
full force and effect, and Lessor shall proceed to make such investigation and
remediation as soon as reasonably possible after the required funds are
available. If Lessee does not give such notice and provide the required funds or
assurance thereof within the time period specified above, this Lease shall
terminate as of the date specified in Lessor's notice of termination.

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

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

10. Real Property Taxes.
     10.1 Payment of Taxes. Lessor shall pay the Real Property Taxes, as defined
in Paragraph 10.2(a), applicable to the Industrial Center, and except as
otherwise provided in Paragraph 10.3, any increases in such amounts over the
Base Real Property Taxes shall be included in the calculation of Common Area
Operating Expenses in accordance with the provisions of Paragraph 4.2.

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

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

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

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

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

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

          (b)  A change in the control of the Lessee shall constitute an
assignment requiring Lessor's consent. The transfer, on a cumulative basis, of
fifty-one percent (51%) or more of the voting control of Lessee shall
constitute a change in control for this purpose.

          (c)  The involvement of Lessee or its assets in any transaction, or
series of transactions (by way of merger, sale, acquisition, financing,
refinancing, transfer, leveraged buy-out or otherwise), whether or not a formal
assignment or hypothecation of this Lease or Lessee's assets occurs, which
results or will result in a reduction of the Net Worth of Lessee, as hereinafter
defined, by an amount equal or greater than fifty-one percent (51%) of such Net
Worth of Lessee as it was represented to Lessor at the time of full execution
and delivery of this Lease or at the time of the most recent assignment to which
Lessor has consented, or as it exists immediately prior to said transaction or
transactions constituting such reduction, at whichever time said Net Worth of
Lessee was or is greater, shall be considered an assignment of the Lease by
Lessee to which Lessor may reasonably withhold its consent. "Net Worth of
Lessee" for purposes of this Lease shall be the net worth of Lessee (excluding
any Guarantors) established under generally accepted accounting principles
consistently applied.

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

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

     12.2 Terms and Conditions Applicable to Assignment and Subletting.

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

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

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

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

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

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

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

     12.3 Additional Terms and Conditions Applicable to Subletting. the
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

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

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

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

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

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

13. DEFAULT; BREACH; REMEDIES.

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

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

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

          (c) Except as expressly otherwise provided in this Lease, the failure
by Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with Applicable Requirements per
paragraph 6.3. (ii) the inspection, maintenance and service contracts

                                                       Initials:
                                                                 ---------------

                                                                 ---------------

<PAGE>
required under Paragraph 7.1(b), (iii) the rescission of an unauthorized
assignment or subletting per Paragraph 12.1, (iv) a Tenancy Statement per
Paragraphs 16 or 37, (v) the subordination or non-subordination of this Lease
per Paragraph 30, (vi) the guaranty of the performance of Lessee's obligations
under this Lease if required under Paragraphs 1, 11 and 37, (vii) the execution
of any document requested under Paragraph 42 (easements), or (viii) any other
documentation or information which Lessor may reasonably require of Lessee under
the terms of this Lease, where any such failure continues for a period of ten
(10) days following written notice by or on behalf of Lessor to Lessee.

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

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

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

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

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

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

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

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

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

     13.3 INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions" shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach (as defined in Paragraph 13.1) of this Lease by Lessee, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor, as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee.

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

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be performed by Lessor. For purposes of this Paragraph 13.5, a reasonable
time may not, based upon the circumstances, be less than thirty (30) days after
receipt by Lessor, and by any Lender(s) whose name and address shall have been
furnished to Lessee in writing for such purpose, of written notice specifying
wherein such obligation of Lessor has not been performed; provided, however,
that if the nature of Lessor's obligation is

                                                           Initials: [ILLEGIBLE]

<PAGE>
such that, more than thirty (30) days after such notice are reasonably required
for its performance, then Lessor shall not be in breach of this Lease if
performance is commenced within such thirty (30) day period and thereafter
diligently pursued to completion.

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

15. Brokers' Fees

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

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

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

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

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

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

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

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

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

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

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

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

23. Notices.

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

    23.2  Date of Notice. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown
on the receipt card, or if no delivery date is shown, the postmark thereon. If
sent by regular mail, the notice shall be deemed given forty-eight (48) hours
after the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantees next day delivery shall be deemed given twenty-four (24) hours after
delivery of the same to the United States Postal Service or courier. If any
notice is transmitted by facsimile transmission or similar means, the same
shall be deemed served or delivered upon telephone or facsimile confirmation of
receipt of the transmission thereof, provided a copy is also delivered via
delivery or mail. If notice is received on a Saturday or a Sunday or a legal
holiday, it shall be deemed received on the next business day.

24. Waivers. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any such act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. Regardless of Lessor's
knowledge of a Default or Breach at the time of accepting rent, the acceptance
of rent by Lessor shall not be a waiver of any Default or Breach by

                                                            Initials [ILLEGIBLE]
                                                                     -----------
                                                                     [ILLEGIBLE]
                                                                     -----------

Lessee of any provision hereof. Any payment given Lessor by Lessee may be
accepted by Lessor on account of monies or damages due Lessor, notwithstanding
any qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

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

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

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

28. Covenants and Conditions. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

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

30. Subordination; Attornment; Non-Disturbance.

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

    30.2 Attornment. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership, (ii) be subject to any offsets or defenses
which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one (1) month's rent.

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

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

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

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

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

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

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

36. Consents

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

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

37. Guarantor

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

    37.2 Additional Obligations of Guarantor. It shall constitute a Default of
the Lessee under this Lease if any such Guarantor fails or refuses, upon
reasonable request by Lessor to give: (a) evidence of the due execution of the
guaranty called for by this Lease, including the authority of the Guarantor (and

                                                                Initials:_______

of the party signing on Guarantor's behalf) to obligate such Guarantor on said
guaranty, and resolution of its board of directors authorizing the making of
such guaranty, together with a certificate of incumbency showing the signatures
of the persons authorized to sign on its behalf, (b) current financial
statements of Guarantor as may from time to time be requested by Lessor, (c) a
Tenancy Statement, or (d) written confirmation that the guaranty is still in
effect.

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

39.   OPTIONS.

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

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

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

      39.4  EFFECT OF DEFAULT ON OPTIONS.

            (a) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary; (i) during
the period commencing with the giving of any notice of Default under Paragraph
13.1 and continuing until the noticed Default is cured, or (ii) during the
period of time any monetary obligation due Lessor from Lessee is unpaid
(without regard to whether notice thereof is given Lessee), or (iii) during
the time Lessee is in Breach of this Lease, or (iv) in the event that Lessor
has given to Lessee three (3) or more notices of separate Defaults under
Paragraph 13.1 during the twelve (12) month period immediately preceding the
exercise of the Option, whether or not the Defaults are cured.

          (b) The period of time within which an Option may be extended or
enlarged by reason of Lessee's inability to exercise an Option because of the
provisions of Paragraph 39.4(a).

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

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

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

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

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

44.  AUTHORITY. If either Party hereto is a corporation, trust, or general or
limited partnership, each individual executing this Lease on behalf of such
entity represents and warrants that he or she is duly authorized to execute and
deliver this Lease on its behalf. If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after request by Lessor,
deliver to Lessor evidence satisfactory to Lessor of such authority.

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

46.  OFFER. Preparation of this Lease by either Lessor or Lessee or Lessor's
agent or Lessee's agent and submission of same to Lessee or Lessor shall not
be deemed an offer to lease. This Lease is not intended to be binding until
executed and delivered by all Parties hereto.

47.  AMENDMENTS. This Lease may be modified only in writing, signed by the
Parties in interest at the time of the modification. The Parties shall amend
this Lease from time to time to reflect any adjustments that are made to the
Base Rent or other rent payable under this Lease. As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by an institutional insurance company or pension plan Lender in
connection with the obtaining of normal financing or refinancing of the
property of which the Premises are a part.

48.  MULTIPLE PARTIES. Except as otherwise expressly provided herein, if more
than one person or entity is named herein as either Lessor or Lessee, the
obligations of such multiple parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor or Lessee.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND
PROVISION CONTAINED HEREIN, AND BY THE EXECUTION OF THIS LEASE SHOW THEIR
INFORMED AND VOLUNTARY CONSENT THERETO. THE PARTIES HEREBY AGREE THAT, AT THE

PREMISES.

     UNDERGROUND STORAGE TANKS OR HAZARDOUS SUBSTANCES. NO REPRESENTATION OR
     RECOMMENDATION IS MADE BY THE AMERICAN INDUSTRIAL REAL ESTATE ASSOCIATION
     OR BY THE REAL ESTATE BROKERS OR THEIR CONTRACTORS, AGENTS OR EMPLOYEES AS
     TO THE LEGAL SUFFICIENCY, LEGAL EFFECT, OR TAX CONSEQUENCES OF THIS LEASE
     OR THE TRANSACTION TO WHICH IT RELATES; THE PARTIES SHALL RELY SOLELY UPON
     THE ADVICE OF THEIR OWN COUNSEL AS TO THE LEGAL AND TAX CONSEQUENCES OF
     THIS LEASE. IF THE SUBJECT PROPERTY IS IN A STATE OTHER THAN CALIFORNIA, AN
     ATTORNEY FROM THE STATE WHERE THE PROPERTY IS LOCATED SHOULD BE CONSULTED.

Paragraph 1
          -

A.   OPTIONS TO EXTEND:

Lessor hereby rants to Lessee the option to extend the term of this Lease for 1
additional 36 month period(s) commencing when the prior term expires upon each
and all of the following terms and conditions:

     (i)   in order to exercise an option to extend, Lessee must give written
notice of such election to Lessor and Lessor must receive the same at least 1
but no more than 6 months prior to the date that the option period would
commence, time being of the essence. If proper notification of the exercise of
an option is not given and/or received, such option shall automatically expire.
Options (if there are more than one) may only be exercised consecutively.

     (ii)  The provision in paragraph 39, including those relating to Lessee's
Default set forth in paragraph 39.4 of this Lease, are conditions of this
option.

     (iii) Except for the provisions of this Lease granting an option or
options to extend the term, all of the terms and conditions of this Lease
except where specifically modified by this option shall apply.

     (iv)  This Option is personal to the original Lessee, and cannot be
assigned or exercised by anyone other than said original Lessee and only while
the original Lessee is in full possession of the Premises and without the
intention of thereafter assigning or subletting.

     (v)   The monthly rent for each month of the option period shall be
calculated as follows: using the method(s) indicated below:
(Check Method(s) to be Used and Fill in Appropriately)

/ /  I. Cost of Living Adjustments (COLA)
     a. On (Fill in COLA Dates):
                                ------------------------------------------------
--------------------------------------------------------------------------------
the Base Rent shall be adjusted by the change, if any, from the Base Month
specified below, in the Consumer Price Index of the Bureau of Labor Statistics
of the U.S. Department of Labor for (select one) / / CPI W (Urban Wage Earners
and Clerical Workers) or / / CPI U (all Urban Consumers) for (Fill in Urban
Area):

--------------------------------------------------------------------------------
All-Items (1982-1984 = 100), herein referred to as "CPI".

     b. The monthly rent payable in accordance with paragraph A.1.a. of this
Addendum shall be calculated as follows: the Base Rent set forth in paragraph
1.5 of the attached Lease, shall be multiplied by a fraction the numerator of
which shall be the CPI of the calendar month two months prior to the month(s)
specified in paragraph A.1.a. above during which the adjustment is to take
effect, and the denominator of which shall be the CPI of the calendar month
which is two months prior to (select one) / / the first month of the term of
this Lease as set forth in paragraph 1.3 ("Base Month") or / / (Fill in Other
"Base Month"):                             . This sum so calculated shall
              -----------------------------
constitute the new monthly rent hereunder, but in no event, shall any such new
monthly rent be less than the rent payable for the month immediately preceding
the rent adjustment.

     c.   In the event the compilation and/or publication of the CPI shall be
transferred to any other governmental department or bureau or agency or shall
be discontinued, then the index most nearly the same as the CPI shall be used
to make such calculation. In the event that the Parties cannot agree on such
alternative Index, then the matter shall be submitted for decision to the
American Arbitration Association in accordance with the then rules of said
Association and the decision of the arbitrators shall be binding upon the
parties. The cost of said Arbitration shall be paid equally by the Parties.

/X/  II. Market Rental Value Adjustment(s)(MRV)
     a.  On (Fill in MRV Adjustment Date(s)): The forty ninth month after the
                                             ----------------------------------
initial lease commencement date.
-------------------------------------------------------------------------------
the Base Rent shall be adjusted to the "Market Rental Value" of the property as
follows:

         1)  Four months prior to each Market Rental Value Adjustment Date
described above, the Parties shall attempt to agree upon what the new MRV will
be on the adjustment date. If agreement cannot be reached, within thirty days,
then:

             (a) Lessor and Lessee shall immediately appoint a mutually
acceptable appraiser or broker to establish the new MRV within the next thirty
days. Any associated costs will be split equally between the Parties, or

             (b) Both Lessor and Lessee shall each immediately make a
reasonable determination of the MRV and submit such determination, in writing.

to arbitration in accordance with the following provisions:

                (i)   Within fifteen days thereafter, Lessor and Lessee shall
each select an [ ] appraiser or [X] broker ("Consultant" - check one) of their
choice to act as an arbitrator. The two arbitrators so appointed shall
immediately select a third mutually acceptable Consultant to act as a third
arbitrator.

               (ii)   The three arbitrators shall within thirty days of the
appointment of the third arbitrator reach a decision as to what the actual MRV
for the Premises is, and whether Lessor's or Lessee's submitted MRV is the
closest thereto. The decision of a majority of the arbitrators shall be binding
on the Parties. The submitted MRV which is determined to be the closest to the
actual MRV shall thereafter be used by the Parties.

              (iii)   If either of the Parties fails to appoint an arbitrator
within the specified fifteen days, the arbitrator timely appointed by one of
them shall reach a decision on his or her own, and said decision shall be
binding on the Parties.

               (iv)   the entire cost of such arbitration shall be paid by the
party whose submitted MRV is not selected, ie. the one that is NOT the closest
to the actual MRV.

          (2)  Notwithstanding the foregoing, the new MRV shall not be less than
the rent payable for the month immediately preceding the rent adjustment.

     b.  Upon the establishment of each New Market Rental Value:

          (1)  the new MRV will become the new "Base Rent" for the purpose of
calculating any further Adjustments, and that rental shall increase by four
percent (4%) each year of the extension period.

[ ] III.  FIXED RENTAL ADJUSTMENT(S) (FRA)

The Base Rent shall be increased to the following amounts on the dates set
forth below:
