Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease.

     THIS AGREEMENT OF SUBLEASE is made as of the 31st day of July, 1998, by and
                                                  ----

California corporation ("Subtenant"), having an office at 275 Saratoga Ave.,
#260, Santa Clara, CA.

                                    WITNESS
                                    -------

     WHEREAS, by Agreement of Lease dated March 5, 1997, as amended (the
"Lease") by and between W.F. Batton and Marie A. Batton, Trustees of the W.F.
Batton Trust UTA dated January 12, 1988, as amended ("Landlord") and
Sublandlord, Landlord leased to Sublandlord certain real property commonly
referred to as 5400 Betsy Ross Drive, Santa Clara, California, consisting of
approximately 3.5 acres of land together with the building (the "Building") and
other improvements constructed thereon, as more particularly described in the
Lease (the "Premises"). A copy of the Lease is attached hereto as Exhibit A and
made a part hereof; and

     WHEREAS, Sublandlord desires to sublease to Subtenant and Subtenant desires
to sublease from Sublandlord a portion of the Premises on the terms and
conditions hereinafter set forth.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained
and for other good and valuable consideration, the parties agree as follows:

     1.   SUBLEASING OF SUBPREMISES. (a) Subject to the written consent of the
          -------------------------
Landlord, Sublandlord hereby subleases to Subtenant and Subtenant hereby
subleases from Sublandlord that portion of the Building containing approximately
19,557 usable square feet, as more particularly shown as the crosshatched area
on the floor plan attached hereto as Exhibit B and made a part hereof (the
"Subpremises"), upon and subject to all of the terms and conditions hereinafter
set forth. Subtenant shall have the right, in common with others, to use: (i)
the parking lot serving the Building for the parking of Subtenant's employees'
cars on a first come, first serve basis, and Common Areas 1, 2, 3 and 5 as
marked on Exhibit B. On January 1, 1999, (the "Additional Subpremises
Commencement Date"), Sublandlord shall sublease to Subtenant that portion of the
Building containing approximately 3,764 rentable square feet, as more
particularly shown on Exhibit B as the "Additional Subpremises." On the
Additional Subpremises Commencement Date, all provisions of this Sublease which
refer to the "Subpremises" shall be deemed to include the Additional
Subpremises.

          (b)  Sublandlord hereby grants Subtenant a right of first refusal on
the sublease of an additional approximately 4,110 usable square feet as marked
on Exhibit B (the "Right of First Refusal Space"). This right of first refusal
shall run throughout the term of this Sublease. In the event Sublandlord desires
to sublease the Right of First Refusal Space, Sublandlord shall give written
notice thereof to Subtenant. The notice shall include terms of the sublease
which shall represent the fair rental value of the Right of First Refusal Space,
as reasonably determined by Sublandlord. For a period of five (5)

                                       1
<PAGE>

business days after receipt by Subtenant of Sublandlord's notice, Subtenant
shall have the right to give written notice to Sublandlord of Sublandlord's
exercise of Subtenant's right to sublease the Right of First Refusal Space on
the terms set forth in the notice. In the event that Sublandlord does not
receive written notice of Subtenant's exercise of the right herein granted
within said five (5) day period, there shall be a conclusive presumption that
Subtenant has elected not to exercise its right hereunder, and Sublandlord may
sublease the Right of First Refusal Space to another on the same terms set forth
in Sublandlord's notice.

     2.   TERM. (a) The term (the "Term") of this Sublease shall commence on the
          ----
completion of the Subtenant Improvement Work (as defined in the Work Letter
Agreement delivered on even date herewith), expected to be on or around August
1, 1998 (the "Commencement Date") and shall continue for a period of sixty (60)
months, unless sooner terminated as hereinafter provided. The Term as it applies
to the Additional Subpremises shall commence on the Additional Subpremises
Commencement Date and shall terminate on the same date as the Term as it applies
to the remaining Subpremises.

          (b)  Sublandlord hereby grants to Subtenant two (2) options to extend
the term of this Lease, the first for a two (2) year period and the second for a
twenty-eight (28) month period, commencing when the prior term expires, upon
each and all of the following terms and conditions: (i) Subtenant gives to
Sublandlord, and Sublandlord actually receives, on a date which is prior to the
date that the option period would commence (if exercised) by at least six (6)
months and not more than nine (9) months, a written notice of the exercise of
the option to extend this Sublease for said additional term, time being of the
essence. If said notification of the exercise of said option is not so given and
received, this option shall automatically expire; (ii) Subtenant is not in
default and never has been in default under this Sublease; (iii) all of the
terms and conditions of the Sublease shall apply except where specifically
modified by this option; and (iv) Base Rent and Additional Rent (as defined
below) shall be at fair market value at the time of commencement of the option
period, but in no event less than the month immediately preceding the
commencement of the option period.

          (c)  Subtenant may terminate this Sublease prior to the end of the
Term, provided that (i) Subtenant provides written notice to Sublandlord and
Landlord of its intent to terminate no less than six (6) months' prior to its
desired date of termination, (ii) Subtenant pays to Sublandlord the Base Rent
and Additional Rent as provided below until such time as Sublandlord finds a
suitable subtenant for the Subpremises and such subtenant begins paying Rent on
the Subpremises, and (iii) Subtenant pays to Sublandlord any commission
obligations, tenant improvement allowance or other external expense incurred by
Sublandlord in re-subletting the Subpremises, or any portion of the Subpremises.
With respect to (ii) in the preceding sentence, if any portion of the
Subpremises is not re-sublet by Sublandlord, Subtenant shall continue to pay
proportionate Rent for such portion which is not re-sublet until such time as
the entire Subpremises is re-sublet by Sublandlord. Sublandlord agrees that,
Subtenant, at its option, may control the marketing of the Subpremises and
present to Sublandlord suitable subtenant candidates. Subject to Landlord's
approval under the Lease, Sublandlord will not unreasonably withhold its consent
to sublet the Subpremises to a subtenant candidate presented by Subtenant. In
the case of the acquisition or merger of Subtenant,

                                       2
<PAGE>

Sublandlord agrees to accept such successor entity as a subtenant for the
Subpremises, subject to Landlord's approval under the Lease.

     3.   BASE RENT.
          ---------

          (a)  During the Term, Subtenant shall say to Sublandlord, in lawful
money of the United States which at the time shall be legal tender in payment of
all debts and dues, public and private, an annual fixed rent (the "Base Rent")
calculated by multiplying the usable square footage of the Subtenant (as
computed in (b) below) plus Subtenant's proportionate share of Common Areas 1,
2, 3 and 5 (the "Rental Square Footage") by the following amounts per square
foot per month, payable in equal monthly installments:


                      MONTHLY BASE RENT RATE      MONTHLY BASE RENT RATE

month during the Term at the office of the Sublandlord, or such other place as
Sublandlord may designate, without any setoff or deduction of any kind
whatsoever. The first payment of Base Rent shall be due on the execution date of
this Sublease.

          (b)  Upon substantial completion of construction of the Subpremises,
and, if reasonably practicable, prior to construction of interior improvements
in the Premises, but in no event later than five (5) days before Subtenant is
tendered occupancy of the Subpremises or actually occupies the Subpremises,
whichever first occurs, an architect or engineer selected by Sublandlord and
Subtenant, in the presence of authorized representatives of Sublandlord and
Subtenant, shall measure the Subpremises and shall agree upon the area
calculations. The usable square footage of the Subpremises shall be computed in
accordance with the currently effective methods of measurement established as
the American National Standard and published by the Building Owners and Managers
Association International, which are hereby adopted and incorporated herein by
reference. The measurements shall be used to determine a revised annual rent,
which shall be approved by authorized representatives of Sublandlord and
Subtenant, signed or initialed, and attached to this Sublease. A copy thereof

     3A.  RENT ADJUSTMENT

     (a)  The following terms shall have the following meanings with respect to
the provisions of this Section 3A.:

          (i)  "Subtenant's Pro Rata Share" shall mean that proportion of the
Operating Expenses for any calendar year that equals the Rental Square Footage
divided by the total number of rentable square feet in the Building.

          (ii) "Operating Expenses" shall:

               (A)  Mean all operating expenses actually incurred of any kind or
nature with respect to the Building as determined in accordance with generally
accepted accounting principles and shall include, but not be limited to, all
general and special real estate or ad valorem taxes or special assessments
levied against the Building by any governmental or quasi-governmental authority
or any taxes or assessments which shall be levied on the Building in lieu of or
in addition to all or any portion of any such real estate taxes or assessments,
or which shall be levied on the rentals of the Building (other than net income
taxes), or which shall be levied on Sublandlord as a result of the use,
ownership or operation of the Building; the cost of Building supplies; costs
incurred in connection with all energy sources for the common areas of the
Building such as propane, butane, natural gas steam, electricity, solar energy
and fuel oil; the costs of water and sewer services; janitorial services;
general maintenance and normal repair of the Building, including the heating and
air conditioning systems of the Building; landscaping maintenance; maintenance,
repair, striping and replacement of all parking areas furnished by Sublandlord
for use by tenants of the Building; the cost of rubbish removal, service
contracts for the elevator, HVAC and alarm systems of the Building; the cost of
such security guard and protection services as may be deemed reasonably
necessary by Sublandlord; insurance in amounts and coverages determined by
Sublandlord, including fire and extended coverage, rental interruption,
sprinkler leakage, plate glass and public liability insurance (but Subtenant
shall have no interest in such insurance or the proceeds thereof); labor costs
incurred in the operation and maintenance of the Building, including wages and
other payments, costs to Sublandlord of Workers' Compensation and disability
insurance, payroll taxes and fringe benefits; professional building management
fees; legal, accounting, inspection and consultation fees incurred in connection
with the Building to the extent required by any governmental authority or any
other inspection or consultation fees required for the normal prudent operation
of the Building and not normally the responsibility of the managing agent; the
cost of any capital improvements to the Building or of any machinery or
equipment installed in the Building which is made or becomes operational, as the
case may be, after the Commencement Date; all other common area costs and
expenses relating to the Building and all other charges properly allocable to
the repair, operation and maintenance of the Building in accordance with
generally accepted accounting principles. If the Building is not fully occupied
during any calendar year, the Operating Expenses for such year shall be adjusted
to reflect the greater of: (a) actual occupancy; or (b) a ninety-five percent
(95%) occupancy of the Building. If Sublandlord selects an accrual accounting
basis for calculating Operating Expenses, Operating Expenses shall be deemed to
have been paid when such expenses have accrued in accordance with generally
accepted accounting principles.

                                       4
<PAGE>

               (B)  Expressly exclude Sublandlord's income taxes; leasing
commissions; interest on debt or amortization payments on any mortgages or deeds
of trust and rental under any ground or underlying leases or lease; advertising
and promotional expenditures; and any other expense which under generally
accepted accounting principles would not be considered a normal maintenance or
operating expense, except as otherwise specifically provided herein.

     (b)  It is hereby agreed that during each calendar year of the term hereof,
Subtenant shall pay to Sublandlord Subtenant's Pro Rata Share of the amount of
any Operating Expenses. Beginning with the first calendar year in which this
Sublease commences, the monthly rent to be paid by Subtenant to Sublandlord
shall be increased by an amount equal to 1/12th of Subtenant's Pro Rata Share of
the Operating Expenses for each calendar year, with an adjustment to be made
between the parties at a later date as hereinafter provided. However, in
computing the monthly rental for Subtenant's Pro Rata Share of the Operating
Expenses for any calendar year, there shall be taken into account any prior
increases in the monthly rent attributable to Subtenant's Pro Rata Share of the
estimated increases in such Operating Expenses. As soon as practicable following
the end of each calendar year during the term of this Sublease, Landlord shall
submit to Subtenant a statement setting forth the exact amount of the increase,
if any, in Subtenant's Pro Rata Share of the Operating Expenses for the calendar
year just completed over Subtenant's Pro Rata Share of the Base Operating
Expenses, and the difference, if any, between Subtenant's actual Pro Rata Share
of the Operating Expenses for the calendar year just completed and the estimated
amount of Subtenant's Pro Rata Share of the Operating Expenses (on which its
rent was based) for such year. Prior to the end of each calendar year during the
term hereof, Sublandlord shall submit to Subtenant a statement setting forth the
amount reasonably estimated by Sublandlord as the increase, if any, in the Base
Operating Expenses for the subsequent year and the amount of the increased
monthly rent to be paid by Subtenant for such subsequent year computed in
accordance with the foregoing provisions. It is to be understood and agreed that
all estimating provisions as referenced above shall be computed on the basis of
the Operating Expenses being adjusted as if the Building were not less than
ninety-five percent (95%) occupied. To the extent that Subtenant's Pro Rata
Share of the actual Operating Expenses for the period covered by such statement
is different from the estimated increases upon which Subtenant paid rent during
the calendar year just completed, Sublandlord shall pay to Subtenant, or
Subtenant shall pay to Sublandlord, as the case may be, the difference within
thirty (30) days following receipt of said statement from Sublandlord. In
addition, with respect to the monthly rent, until Subtenant receives such
statement, Subtenant's monthly rent for the new calendar year shall continue to
be paid at the then current rate, but Subtenant shall commence payment to
Sublandlord of the monthly installments of rent on the basis of the statement
beginning on the first day of the month following the month in which Subtenant
receives such statement. Moreover, Subtenant shall pay to Sublandlord, or shall
receive a credit against the next installment due hereunder, as the case may be,
on the date required for the first payment of rent as adjusted, the difference,
if any, between the monthly installments of rent so adjusted and the monthly
installments of rent actually paid during the new calendar year. In no event
shall any adjustment hereunder result in a decrease in the Base Rent or
additional rent payable pursuant to any other provision of this Lease (except
escalation pursuant to this Section 3A), it being agreed that the payments under
this Section 3A are an obligation supplemental to Subtenant's obligation to pay
the Base Rent.

                                       5
<PAGE>

     (c)  If Subtenant occupies the Subpremises for less than a full calendar
year during the first or last calendar years of the term hereof, Subtenant's Pro
Rata Share for such partial year shall be calculated by proportionately reducing
the Base Operating Expenses to reflect the number of months in such year during
which Subtenant occupied the Premises (the "Adjusted Base Operating Expenses").
The Adjusted Base Operating Expenses shall then be compared with the actual
Operating Expenses for said partial year to determine the amount, if any, of any
increases in the actual Operating Expenses for such partial year over the
Adjusted Base Operating Expenses. Subtenant shall pay its Pro Rata Share of any
such increases within thirty (30) days following receipt of notice thereof.

     (d)  Sublandlord's failure during the Lease term to prepare and deliver any
statement or bills, or Sublandlord's failure to make a demand under this Section
or under any other provision of this Sublease shall not in any way be deemed to
be a waiver of, or cause Sublandlord to forfeit or surrender, its rights to
collect any items of additional rent which may have become due pursuant to this
Section during the term of this Sublease, except as otherwise specifically set
forth in this Sublease. Subtenant's liability for all additional rent due under
this Section 3A shall survive the expiration or earlier termination of this
Sublease.

     (e)  Subtenant shall have the right to be exercised within ninety (90) days
following receipt of Sublandlord's statement, to review Sublandlord's actual
operating expenses during regular business hours upon ten (10) days written
notice.

4.   ADDITIONAL RENT.
     ---------------

          (a)  All amounts payable by Subtenant to Sublandlord pursuant to this
Sublease, including, without limitation, Base Rent and any additional rent
required by the terms hereof, shall be deemed to constitute rent and, in the
event of any non-payment thereof, Sublandlord shall have all of the rights and
remedies provided herein, in the Lease, at law or in equity for non-payment of
rent.

          (b)  Subtenant's obligation to pay additional rent hereunder shall be
on account of the period from and after the Rent Commencement Date and shall
survive the Expiration Date or sooner termination of the Term.

          (c)  The items of additional rent as provided in this Agreement of
Sublease shall be billed to Subtenant by Sublandlord (whether or not such items
have been incurred by the time of billing) within thirty (30) days of incursion
by Landlord. Subtenant shall have thirty (30) days after receipt of such
statement to reimburse Sublandlord for these costs.

     5.   SUBORDINATION TO AND INCORPORATION OF TERMS OF LEASE
          ----------------------------------------------------

          (a)  This Sublease is in all respects subject and subordinate to the
terms and conditions of the Lease and to the matters to which the Lease is or
shall be subordinate. Except as otherwise expressly provided in this Sublease,

Subtenant (as if they were the Landlord and Tenant, respectively, under the
Lease and as if the Subpremises being sublet hereby were the Lease Premises
demised under the Lease), constitute the terms of this Sublease, except to the
extent that they do not relate to the Subpremises or are inapplicable to,
inconsistent with, or modified or eliminated by, the terms of this Sublease. The
parties agree that the following terms of the Lease do not apply to this
Sublease: Sections 1, 2a, 2b, 2d, 3, 4, 6a, 11, 12c, 15, 23, 25, 31, 34 and the
Exhibits to the Lease. Sublandlord and Subtenant acknowledge and agree that
Subtenant has reviewed and is familiar with the Lease and Sublandlord hereby
represents that the copy delivered to Subtenant for such purpose and attached
hereto as Exhibit A is a true, correct and complete copy of such Lease and that
the Lease represents the entire agreement between Sublandlord and Landlord with
respect to the lease of the Premises. Sublandlord also represents that (i) there
is no default, or any condition which with the passage of time or the giving of
notice, or both, would constitute a default, on the part of either party to the
Lease, (ii) Sublandlord has not assigned, encumbered or otherwise transferred
any interest of Tenant under the Lease, and (ii) the Commencement Date of the
Lease was September 1, 1997 and the scheduled expiration date of the Lease is

          (b)  In the event of a default by Sublandlord, as Tenant under the
Lease, resulting in the termination, reentry or dispossession thereunder,
Landlord may, at its option, and Sublandlord shall use reasonable efforts to
cause Landlord to, take over all of the right, title and interest of Sublandlord
under this Sublease and Subtenant hereunder shall, at the option of the
Landlord, attorn to and recognize Landlord as Sublandlord hereunder except that
Landlord shall not (i) be liable for any previous act or omission of Sublandlord
under this Sublease, (ii) be subject to any offset, not expressly provided for

prepayment of more than one month's rent, and shall, promptly upon Landlord's
request, execute and deliver all instruments necessary or appropriate to confirm
such attornment and recognition. Subtenant hereby waives all rights under any
present or future law to elect, by reason of the termination of such Lease, to
terminate this Sublease or surrender possession of the Subpremises.

     6.   CARE, SURRENDER AND RESTORATION OF THE SUBPREMISES.

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

          --------
thing, whenever Sublandlord's consent or approval is required under this
Sublease or under the Lease, as incorporated herein, shall be deemed reasonable
if Landlord has refused or failed to give its consent or approval to such matter
or thing.

     18.  CONDITION OF THE SUBPREMISES; SUBTENANT'S CHANGES.
          -------------------------------------------------

          (a)  Subtenant represents it has made a thorough examination of the
Subpremises and it is familiar with the condition thereof. Subtenant
acknowledges that it enters into this Sublease without any representation or
warranties by Sublandlord except as set forth in this Lease, or anyone acting or
purporting to act on behalf of Sublandlord, as to the present or future
conditions of the Subpremises or the appurtenances thereto or any improvements
therein or of the Building. Sublandlord represents that upon commencement of
this Sublease, the roof, HVAC systems, electric and plumbing systems, the

          (b)  Notwithstanding anything to the contrary contained in the Lease,
Subtenant shall not make any changes to the Subpremises whatsoever, including,
without limitation, structural or non-structural changes, without the prior
written consent of Sublandlord and Landlord. All permitted alterations or
additions shall be constructed in accordance with the requirements of the Lease.

     19.  ASSIGNMENT AND SUBLETTING. Subtenant, for itself, its successors and
assigns, expressly covenants that it shall not assign, whether by operation of
law or otherwise, or pledge or otherwise encumber this Sublease, or sublet all
or any part of the Subpremises. Any purported assignment, pledge, encumbrance or
sublease by Subtenant shall be void and of no force or effect and shall
constitute a default by Subtenant hereunder. Subject to complying with the
provisions of the Lease, Sublandlord reserves the right to transfer and assign
its interest in and to this Sublease to any entity or person who shall succeed
to Sublandlord's interest in and to the Lease.

     20.  INSURANCE.
          ---------

          (a)  Subtenant agrees to maintain in responsible companies qualified
to do business, and in good standing, in California (i) public liability
insurance covering the Subpremises insuring Landlord and Sublandlord as well as
Subtenant (to the extent of

                                      11
<PAGE>

Subtenant's negligence) with limits which shall be equal to those required to be
maintained by Sublandlord under the Lease, and naming Sublandlord and Landlord
as additional insureds, (ii) Worker's Compensation Insurance with statutory
limits covering all of Subtenant's employees working in the Subpremises, and
(iii) Commercial All-Risk Property Insurance written on an all risk of loss
form, and on a replacement cost basis, covering Subtenant's personal property
and leasehold improvements. Subtenant shall deposit promptly with Sublandlord
certificates for such insurance, and all renewals thereof, bearing the
endorsement that the policies will not be canceled until after thirty (30) days
written notice to both Sublandlord and Landlord. Subtenant shall pay all
premiums and charges for such insurance, and if Subtenant shall fail to obtain
such insurance, Sublandlord may, but shall not be obligated to, obtain the same,
in which event the amount of the premium paid shall be paid by Subtenant to
Sublandlord upon Sublandlord's demand therefor, shall be deemed Additional Rent
and shall be collectible by Sublandlord in the same manner and with the same
remedies as though said sums were Additional Rent reserved hereunder.

          (b)  Subtenant acknowledges that Sublandlord will not carry any
insurance in favor of Subtenant, and that neither Landlord nor Sublandlord will
carry insurance on Subtenant's furniture and/or furnishings or any fixtures or
equipment, improvements or appurtenances of Subtenant in or about the
Subpremises.

     21.  WAIVER OF SUBROGATION.
          ---------------------

          (a)  Anything in Section 19 of this Sublease to the contrary
notwithstanding, Sublandlord and Subtenant shall each endeavor to secure an
appropriate clause in, or an endorsement upon, any fire or extended coverage
insurance policy obtained by it and covering the Subpremises or the personal
property, fixtures and equipment located therein or thereon, pursuant to which
the respective insurance companies waive subrogation or permit the insured,
prior to any loss, to agree with a third party to waive any claim it might have
against such third party. The waiver of subrogation or permission for waiver of
any claim herein before referred to shall extend to the agents of each party and
its employees. If, and to the extent that such waiver or permission can be
obtained only upon payment of an additional charge, then, except as provided
herein, the party benefiting from the waiver or permission shall pay such charge
upon demand, or shall be deemed to have agreed that the party obtaining the
insurance coverage in question shall be free of any further obligations under
the provisions hereof relating to such waiver or permission.

          (b)  Subject to the provisions of this Section 21, and insofar as may
be permitted by the terms of the insurance policies carried by it, each party
hereby releases the other with respect to any claim (including a claim for
negligence) which it might otherwise have against the other party for loss,
damage or destruction with respect to its property by fire or other casualty.

     22.  END OF TERM. If Subtenant shall remain in possession of the
          -----------
Subpremises or any part thereof after the expiration or prior termination of the
Term hereof, the parties agree that no such holding over by Tenant shall operate
to extend or renew this Sublease, and that any such holding over shall be
construed as a tenancy-at-will as per Section 17 of the Lease when such holding
over shall have commenced, and such

                                      12
<PAGE>

tenancy shall otherwise be subject to all the terms, conditions, covenants and
agreements of this Sublease. Subtenant further agrees to pay to Sublandlord any
additional amounts payable by Sublandlord to Landlord under the Lease by reason
of any such holding over by Subtenant.

     23.  DEFAULT.
          -------

          (a)  In the event that Subtenant shall default in the payment of
Annual Fixed Rent, Additional Rent or any other charge payable hereunder, or
shall default in the performance or observance of any of the terms, conditions
and covenants of this Sublease, Sublandlord, in addition to and not in
limitation of any rights otherwise available to it, shall have the same rights
and remedies with respect to such default as are provided to Landlord under the
Lease with respect to defaults by Sublandlord as Tenant thereunder, with the
same force and effect as though all such provisions relating to any such default
or defaults were set forth herein in their entirety, and Subtenant shall have
all of the obligations of the Tenant under the Lease with respect to such
default or defaults.

          (b)  In the event of a default by Subtenant in the performance of any
of its non-monetary obligations hereunder, Sublandlord may, at its option, and
without waiving any other remedies for such default herein or at law or by
incorporation by reference of the Lease provided, at any time thereafter, give
written notice to Subtneant that if such default is not cured, or the cure not
commenced, within twenty (20) days after receipt of such notice by Subtenant,
and if so commenced is not thereafter pursued diligently to completion,
Sublandlord may cure such default for the account of Subtenant, and any amount
paid or incurred by Sublandlord in so doing shall be deemed paid or incurred for
the account of Subtenant and Subtenant agrees promptly to reimburse Sublandlord
therefor and save Sublandlord harmless therefrom; provided, however, that
Sublandlord may cure any such default as aforesaid prior to the expiration of
any waiting period if reasonably necessary to protect Sublandlord's interest
under the Lease or to prevent injury or damage to persons or property.

     24.  DESTRUCTION, FIRE AND OTHER CASUALTY. If the whole or any part of the
          ------------------------------------
Subpremises or the Building shall be damaged by fire or other casualty and the
Lease is not terminated on account thereof by either Sublandlord or Landlord in
accordance with the terms thereof, this Sublease shall remain in full force and
effect and Base Rent and Additional Rent shall not abate except to the extent
Base Rent and Additional Rent for the Subpremises shall abate under the terms of
the Lease.

               ---------

provision of the Sublease and Sublandlord shall be entitled to any other remedy
available to it under this Sublease, the Lease or by law. The funds drawn by
Sublandlord under the Letter of Credit shall be nonrefundable and, once applied
to Subtenant's obligations under the Sublease, shall remain the property of

Subtenant) an original statement signed by a person who purports to be an
authorized representative of Sublandlord stating that Sublandlord is entitled to
draw on the Letter of Credit in the amount of the requested draw in accordance

final. Sublandlord shall supervise Devcon and the performance of the Subtenant
Improvement Work. Subtenant may also retain at Subtenant's sole expense a
construction supervisor who shall act as Subtenant's representative during

Subtenant Improvement Work plus applicable warranties on equipment installed.

the subcontractor bid in question.

performance of the Subtenant Improvement Work. The entire balance of the total
cost of the Tenant Improvement Work, including any construction cost overruns,
shall be paid by Subtenant. Once the bid of Devcon and its subcontractors has
been obtained, Sublandlord shall deliver to Subtenant a final estimate of the
Total Cost of the Subtenant Improvement Work (as defined below). If the Total
Cost of the Subtenant Improvement Work exceeds said sum of Six Hundred Twenty
Thousand Dollars ($620,000), Subtenant shall have the right to approve any
engineers, subcontractors, or other professionals whose fees are not included in
Sublandlord's contribution to the cost of the Subtenant Improvement Work.
