Lease Forms

  • Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. 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.
  • 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 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.
  • When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

  B. Time for Payment. Full monthly rent is due in advance on the first day of
each calendar month. In the event that the term of this Lease commences on a
date other than the first day of a calendar month, on the date of commencement
of the term hereof Tenant shall pay to Landlord as rent for the period from such
date of commencement to the first day of the next succeeding calendar month that
proportion of the monthly rent hereunder which the number of days between such
date of commencement and the first day of the next succeeding calendar month
bears to thirty (30). In the event that the term of this Lease for any reason
ends on a date other than the last day of a calendar month, on the first day of
the last calendar month of the term hereof Tenant shall pay to Landlord as rent
for the period from said first day of said last calendar month to and including
the last day of the term hereof that proportion of the monthly rent hereunder
which the number of days between said first day of said last calendar month and
the last day of the term hereof bears to thirty (30).

  C. Late Charge. Notwithstanding any other provision of this Lease, if Tenant

days. Said late charge shall equal ten percent (10%) of each rental payment so
in default.

  D. Additional Rent. Beginning with the commencement date of the term of this
Lease, Tenant shall pay to Landlord or to Landlord's designated agent in
addition to the Basic Rent and as Additional Rent the following:

     (a) All Taxes relating to the Premises as set forth in Paragraph 9, and
     (b) All insurance premiums relating to the Premises, as set forth in
Paragraph 12, and
     (c) All charges, costs and expenses, which Tenant is required to pay
hereunder, together with all interest and penalties, costs and expenses
including reasonable attorneys' fees and legal expenses, that may accrue thereto
in the event of Tenant's failure to pay such amounts, and all damages,
reasonable costs and expenses which Landlord may incur by reason of default of
Tenant or failure on Tenant's part to comply with the terms of this Lease. In
the event of nonpayment by Tenant of Additional Rent, Landlord shall have all
the rights and remedies with respect thereto as Landlord has for nonpayment of
rent.

  The Additional Rent due hereunder shall be paid to Landlord or Landlord's
agent (i) within five days  for taxes and insurance and within thirty days for
all other Additional Rent items after presentation of invoice from Landlord or
Landlord's agent setting forth such Additional Rent and/or (ii) at the option of
Landlord, Tenant shall pay to Landlord monthly, in advance, Tenant's prorata
share of an amount estimated by Landlord to be Landlord's approximate average
monthly expenditure for such Additional Rent items, which estimated amount shall
be reconciled within 120 days of the end of each calendar year or more
frequently if Landlord elects to do so at Landlord's sole and absolute
discretion as compared to Landlord's actual expenditure for said Additional Rent
items, with Tenant paying to Landlord, upon demand, any amount of actual
expenses expended by Landlord in excess of said estimated amount, or Landlord
crediting to Tenant (providing Tenant is not in default in the performance of
any of the terms, covenants and conditions of this Lease) any amount of
estimated payments made by Tenant in excess of Landlord's actual expenditures
for said Additional Rent Items. Within thirty (30) days after receipt of
Landlord's reconciliation, Tenant shall have the right, at Tenant's sole
expense, to audit, at a mutually convenient time at Landlord's office,
Landlord's records relating to the foregoing expenses. Such audit must be
conducted by Tenant or an independent nationally recognized accounting firm that
is not being compensated by Tenant or other third party on a contingency fee
basis. Landlord shall be provided a complete copy of said audit at no expense to
Landlord. If such audit reveals that Landlord has overcharged Tenant and the
audit is not challenged by Landlord, the amount overcharged shall be credited to
Tenant's account within thirty (30) days after the audit is concluded.

  The respective obligations of Landlord and Tenant under this paragraph shall
survive the expiration or other termination of the term of this Lease, and if
the term hereof shall expire or shall otherwise terminate on a day other than
the last day of a calendar year, the actual Additional Rent incurred for the
calendar year in which the term hereof expires or otherwise terminates shall be
determined and settled on the basis of the statement of actual Additional Rent
for such calendar year and shall be prorated in the proportion which the number
of days in such calendar year preceding such expiration or termination bears to
365.

     --------------------
this Lease, Tenant shall pay to Landlord, in addition to the Basic Rent and
Additional Rent, a fixed monthly management fee ("Management Fee") equal to 3%

  F. Place of Payment of Rent and Additional Rent. All Basic Rent hereunder and
all payments hereunder for Additional Rent shall be paid to Landlord at the
office of Landlord at A&P Foundations, 2560 Mission College Blvd., Suite 101,
                      -------------------------------------------------------
Santa Clara, CA 95054 or to such other person or to such other place as Landlord
---------------------
may from time to time designate in writing.

* G. Security Deposit. Concurrently with Tenant's execution of this Lease,
Tenant shall deposit with Landlord the sum of   TWO HUNDRED FORTY TWO THOUSAND
                                              ---------------------------------
FIVE HUNDRED THIRTEEN AND NO/100 Dollars ($ 242,513.00  ----------------------).
--------------------------------            -----------------------------------

Said sum shall be held by Landlord as a Security Deposit for the faithful
performance by Tenant of all of the terms, covenants, and conditions of this
Lease to be kept and performed by Tenant during the term hereof. If Tenant
defaults with respect to any provision of this Lease, including, but not limited
to, the provisions relating to the payment of rent and any of the monetary sums
due herewith, Landlord may (but shall not be required to) use, apply or retain
all or any part of this Security Deposit for the payment of any other amount

<PAGE>

any other loss or damage which Landlord may suffer by reason of Tenant's
default. If any portion of said Deposit is so used or applied, Tenant shall,
within ten (10) days after written demand therefor, deposit cash with Landlord
in the amount sufficient to restore the Security Deposit to its original amount.
Tenant's failure to do so shall be a material breach of this Lease. Landlord
shall not be required to keep this Security Deposit separate from its general
funds, and Tenant shall not be entitled to interest on such Deposit. If Tenant
fully and faithfully performs every provision of this Lease to be performed by
it, the Security Deposit or any balance thereof shall be returned to Tenant (or
at Landlord's option, to the last assignee of Tenant's interest hereunder) at
the expiration of the Lease term and after Tenant has vacated the Premises. In
the event of termination of Landlord's interest in this Lease, Landlord shall
transfer said Deposit to Landlord's successor in interest whereupon Tenant
agrees to release Landlord from liability for the return of such Deposit or the
accounting therefor.

5. ACCEPTANCE AND SURRENDER OF PREMISES By entry hereunder Tenant accepts the
Premises as being included in good and sanitary order, condition and repair, and
accepts the building and improvements included in the Premises in their present
condition, subject to Landlord's obligation to complete the improvements
described in Exhibit B hereto and to Paragraph 52, and without representation or
             ---------
warranty by Landlord as to the condition of such building or as to the use or
occupancy which may be made thereof. Any exceptions to the foregoing must be by
written agreement executed by Landlord and Tenant. Tenant agrees on the last day
of the Lease term, or on the sooner termination of this Lease, to surrender the
Premises promptly and peaceably to Landlord in good condition and repair (damage
by Acts of God, fire, normal wear and tear excepted), with all interior walls
painted, or cleaned so that they appear freshly painted, and repaired and
replaced, if damaged; all floors cleaned and waxed; all carpets cleaned and
shampooed; all broken, marred or nonconforming accoustical ceiling tiles
replaced; all windows washed; the airconditioning and heating systems serviced
by a reputable and licensed service firm and in good operating condition and
repair; the plumbing and electrical systems and lighting in good order and
repair, including replacement of any burned out or broken light bulbs or
ballasts; the lawn and shrubs in good condition including the replacement of any
dead or damaged plantings; the sidewalk, driveways and parking areas in good
order, condition and repair; together with all alterations, additions, and
improvements which may have been made in, to, or on the Premises (except
moveable trade fixtures installed at the expense of Tenant) except that Tenant
shall ascertain from Landlord within thirty (30) days before the end of the term
of this Lease whether Landlord desires to have the Premises or any part or parts
thereof restored to their condition and configuration as when the Premises were
delivered to Tenant and if Landlord shall so desire, then Tenant shall restore
said Premises or such part or parts thereof before the end of this Lease at
Tenant's sole cost and expense. Tenant, on or before the end of the term or
sooner termination of this Lease; shall remove all of Tenant's personal property
and trade fixtures from the Premises, and all property not so removed on or
before the end of the term or sooner termination of this Lease shall be deemed
abandoned by Tenant and title to same shall thereupon pass to Landlord without
compensation to Tenant. Landlord may, upon termination of this Lease, remove all
moveable furniture and equipment so abandoned by Tenant, at Tenant's sole cost,
and repair any damage caused by such removal at Tenant's sole cost. If the
Premises be not surrendered at the end of the term or sooner termination of this
Lease, Tenant shall indemnify Landlord against loss or liability resulting from
the delay by Tenant in so surrendering the Premises including, without
limitation, any claims made by any succeeding tenant founded on such delay.
Nothing contained herein shall be construed as an extension of the term hereof
or as a consent of Landlord to any holding over by Tenant. The voluntary or
other surrender of this Lease or the Premises by Tenant or a mutual cancellation
of this Lease shall not work as a merger and, at the option of Landlord, shall
either terminate all or any existing subleases or subtenancies or operate as an
assignment to Landlord of all or any such subleases or subtenancies.

6. ALTERATIONS AND ADDITIONS   Tenant shall not make, or suffer to be made, any
alteration or addition to the Premises, or any part thereof, without the written
consent of Landlord first had and obtained by Tenant (such consent not to be
unreasonably withheld), but at the cost of Tenant, and any addition to, or
alteration of, the Premises, except moveable furniture and trade fixtures, shall
at once become a part of the Premises and belong to Landlord. Landlord reserves
the right to reasonably approve all contractors and mechanics proposed by Tenant
to make such alterations and additions. Tenant shall retain title to all
moveable furniture and trade fixtures placed in the Premises. All heating,
lighting, electrical, airconditioning, floor to ceiling partitioning, drapery,
carpeting, and floor installations made by Tenant, together with all property
that has become an integral part of the Premises, shall not be deemed trade
fixtures. Tenant agrees that it will not proceed to make such alteration or
additions, without having obtained consent from Landlord to do so, (which
consent shall not be unreasonably withheld by Landlord), and until five (5) days
from the receipt of such consent, in order that Landlord may post appropriate
notices to avoid any liability to contractors or material supplies for payment
for Tenant's improvements. Tenant will at all times permit such notices to be
posted and to remain posted until the completion of work. Tartar shall, if
required by Landlord, secure at Tenant's own cost and expense, a completion and
lien indemnity bond, satisfactory to Landlord, for such work. Tenant further
covenants and agrees that any mechanic's lien filed against the Premises for
work claimed to have been done for, or materials claimed to have been furnished
to Tenant, will be discharged by Tenant, by bond or otherwise, within ten (10)
days after the filing thereof, at the cost and expense of Tenant. Any exceptions
to the foregoing must be made in writing and executed by both Landlord and
Tenant.

7. TENANT MAINTENANCE   Tenant shall, at its sole cost and expense, keep and
maintain the Premises (including appurtenances) and every part thereof in a high
standard of maintenance and repair, and in good and sanitary condition. Tenant's
maintenance and repair responsibilities herein referred to include, but are not
limited to janitorization, plumbing systems within the non-common areas of the
Premises (such as water and drain lines, sinks), electrical systems within the
non-common areas of the Premises (such as outlets, lighting fixtures, lamps,
bulbs, tubes, ballasts), heating and airconditioning controls within the non-
common areas of the Premises (such as mixing boxes, thermostats, time clocks,
supply and return grills), all interior improvements within the premises
including but not limited to: wall coverings, window coverings, acoustical
ceilings, vinyl tile, carpeting, partitioning, doors (both interior and
exterior, including closing mechanisms, latches, locks), and all other interior
improvements of any nature whatsoever. Tenant agrees to provide carpet shields
under all rolling chairs or to otherwise be responsible for war and tear of the
carpet caused by such rolling chairs if such wear and tear exceeds that caused
by normal foot traffic in surrounding areas. Areas of excessive wear shall be
replace at Tenant's sole expense upon Lease termination.

9. TAXES
  A. As Additional Rent and in accordance with Paragraph 4D of this Lease,
Tenant shall pay to Landlord, or if Landlord so directs, directly to the Tax
Collector, all Real Property Taxes relating to the Premises. In the event the
Premises leased hereunder consist of only a portion of the entire tax parcel,
Tenant shall pay to Landlord Tenant's proportionate share of such real estate
taxes allocated to the leased Premises by square footage or other reasonable
basis as calculated and determined by Landlord. If the tax billing pertains 100%
to the leased Premises, and Landlord chooses to have Tenant pay said real estate
taxes directly to the Tax Collector, then in such event it shall be the
responsibility of Tenant to obtain the tax and assessment bills and pay, prior
to delinquency, the applicable real property taxes and assessments pertaining to
the leased Premises, and failure to receive a bill for taxes and/or assessments
shall not provide a basis for cancellation of or nonresponsibility for payment
of penalties for nonpayment or late payment by Tenant. The term "Real Property
Taxes", as used herein, shall mean (i) all taxes, assessments, levies and other
charges of any kind or nature whatsoever, general and special, foreseen and
unforeseen (including all installments of principal and interest required to pay
any general or special assessments for public improvements and any increases
resulting from reassessments caused by any change in ownership of the Premises)
now or hereafter imposed by any governmental or quasi-governmental authority or
special district having the direct or indirect power to tax or levy assessments,
which are levied or assessed against, or with respect to the value, occupancy or
use of, all or any portion of the Premises (as now constructed or as may at any
time hereafter be constructed, altered or otherwise changed) or Landlord's
interest therein; any improvements located within the Premises (regardless of
ownership); the fixtures, equipment and other property of Landlord, real or
personal, that are an integral part of and located in the Premises; or parking
areas, public utilities, or energy within the Premises; (ii) all charges, levies
or fees imposed by reason of environmental regulation or other governmental
control of the Premises; and (iii) all costs and fees (including

                                       3
<PAGE>

reasonable attorneys' fees) incurred by Landlord in reasonably contesting any
Real Property Tax and in negotiating with public authorities as to any Real
Property Tax. If at any time during the term of this Lease the taxation or
assessment of the Premises prevailing as of the commencement date of this Lease
shall be altered so that in lieu of or in addition to any Real Property Tax
described above there shall be levied, assessed or imposed (whether by reason of
a change in the method of taxation or assessment, creation of a new tax or
charge, or any other cause) an alternate or additional tax or charge (i) on the
use or occupancy of the Premises or Landlord's interest therein or (ii)
on ore measured by the gross receipts, income or rentals from the Premises, on
Landlord's business of leasing the Premises, or computed in any manner with
respect to the operation of the Premises, then any such tax or charge, however
designated shall be included within the meaning of the term "Real Property
Taxes" for purposes of this Lease. If any Real Property Tax is based upon
property or rents unrelated to the Premises, then only that part of such Real
Property Tax that is fairly allocable to the Premises shall be included within
the meaning of the term "Real Property Taxes". Notwithstanding the foregoing,
the term "Real Property Taxes" shall not include estate, inheritance, gift or
franchise taxes of Landlord or the federal or state net income tax imposed on
Landlord's income from all sources.

  B. Taxes on Tenant's Property. Tenant shall be liable for and shall pay ten
days before delinquency, taxes levied against any personal property or trade
fixtures placed by Tenant in or about the Premises. If any such taxes on
Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property or of the assessed value of the Premises is increased by the
inclusion therein of a value placed upon such personal property or trade
fixtures of Tenant and if Landlord, after written notice to Tenant, pays the
taxes based on such increased assessment, which Landlord shall have the right to
do regardless of the validity thereof, but only under proper protest if
requested by Tenant. Tenant shall upon demand, as the case may be, repay to
Landlord the taxes so levied against Landlord, or the proportion of such taxes
resulting from such increase in the assessment; provided that in any such event
Tenant shall have the right, in the name of Landlord and with Landlord's full
cooperation, to bring suit in any court of competent jurisdiction to recover
the amount of such taxes so paid under protest, and any amount so recovered
shall belong to Tenant.

10. LIABILITY INSURANCE   Tenant, at Tenant's expense, agrees to keep in force
during the term of this Lease a policy of commercial general liability insurance
with combined single limit coverage of not less than Two Million Dollars
($2,000,000) per occurrence  for bodily injury and property damage occurring in,
on or about the Premises, including parking and landscaped areas. Such insurance
shall be primary and noncontributory as respects any insurance carried by
Landlord.  The policy or policies effecting such insurance shall name Landlord
as additional insureds, and shall insure any liability of Landlord, contingent
or otherwise, as respects acts or omissions of Tenant, its agents, employees or
invitees or otherwise by any conduct or transactions of any of said persons in
or about or concerning the Premises, including any failure of Tenant to observe
or perform any of its obligations hereunder; shall be issued by an insurance
company admitted to transact business in the State of California; and shall
provide that the insurance effected thereby shall not be canceled, except upon
thirty (30) days prior written notice to Landlord. A certificate of insurance of
said policy shall be delivered to Landlord. If, during the term of this Lease,
in the considered opinion of Landlord's Lender, insurance advisor, or counsel,
the amount of insurance described in this Paragraph 10 is not adequate, Tenant
agrees to increase said coverage to such reasonable amount as Landlord's Lender,
insurance advisor, or counsel shall deem adequate.

11. TENANT'S PERSONAL PROPERTY INSURANCE AND WORKMAN'S COMPENSATION INSURANCE
Tenant shall maintain a policy or policies of fire and property damage insurance
in "all risk" form with a sprinkler leakage endorsement insuring the personal
property, inventory, trade fixtures, and leasehold improvements within the
leased Premises for the full replacement value thereof. The proceeds from any of
such policies shall be used for the repair or replacement of such items so
insured.

  Tenant shall also maintain a policy or policies of workman's compensation
insurance and any other employee benefit insurance sufficient to comply with all
laws.

12. PROPERTY INSURANCE   Landlord shall purchase and keep in force, and as
Additional Rent and in accordance with Paragraph 4D of this Lease, Tenant shall
pay to Landlord (or Landlord's agent if so directed by Landlord) Tenant's
proportionate share (allocated to the leased Premises by square footage or
other equitable basis as calculated and determined by Landlord) of the
deductibles on insurance claims and the cost of, policy or policies of insurance
covering loss or damage to the Premises (excluding routine maintenance and
repairs and incidental damage or destruction caused by accidents or vandalism
for which Tenant is responsible under Paragraph 7) in the amount of the full
replacement value thereof, providing protection against those perils included
within the classification of "all risks" insurance and flood and/or earthquake
insurance, if available, plus a policy of rental income insurance in the amount
of one hundred (100%) percent of twelve (12) months Basic Rent, plus sums paid
as Additional Rent. If such insurance cost is increased due to Tenant's use of
the Premises, Tenant agrees to pay to Landlord the full cost of such increase.
Tenant shall have no interest in nor any right to the proceeds of any insurance
procured by Landlord for the Premises.

  Landlord and Tenant do each hereby respectively release the other, to the
extent of insurance coverage of the releasing party, from any liability for loss
or damage caused by fire or any of the extended coverage casualties included in
the releasing party's insurance policies, irrespective of the cause of such fire
or casualty; provided, however, that if the Insurance policy of either releasing
party prohibits such waiver, then this waiver shall not take effect until
consent to such waiver is obtained. If such waiver is so prohibited, the
insured party affected shall promptly notify the other party thereof.

13. INDEMNIFICATION   Landlord shall not be liable to Tenant and Tenant hereby
waives all claims against Landlord for any injury to or death of any person or
damage to or destruction of property in or about the Premises by or from any
cause whatsoever, including, without limitation, gas, fire, oil, electricity
or leakage of any character from the roof, walls, basement or other portion of
the Premises but excluding, however, the willful misconduct or negligence of
Landlord, its agents, servants, employees, invitees, or contractors of which
negligence Landlord has knowledge and reasonable time to correct. Except as to
injury to persons or damage to property to the extent arising from the willful
misconduct or the negligence of Landlord, its agents, servants, employees,
invitees, or contractors. Tenant shall hold Landlord harmless from and defend
Landlord against any and all expenses, including reasonable attorneys' fees,
in connection therewith, arising out of any injury to or death of any person
or damage to or destruction of property occurring in, on or about the
Premises, or any part thereof, from any cause whatsoever.

14. COMPLIANCE   Tenant, at its sole cost and expense, shall promptly comply
with all laws, statutes, ordinances and governmental rules, regulations or
requirements now or hereafter in effect; with the requirements of any board of
fire underwriters or other similar body now or hereafter constituted; and with
any direction or occupancy certificate issued pursuant to law by any public
officer pertaining to Tenant's business and operations within the Premises or
Tenant's use of the Premises; provided, however, that no such failure shall be
deemed a breach of the provisions if Tenant, immediately upon notification,
commences to remedy or rectify said failure.  The judgement of any court of
competent jurisdiction of the admission of Tenant in any action against Tenant,
whether Landlord be a party thereto or not, that Tenant has violated any such
law, statute, ordinance or governmental rule, regulation, requirement, direction
or provision, shall be conclusive of that fact as between Landlord and  Tenant.
Tenant shall, at its sole cost and expense, comply with any and all requirements
pertaining to said Premises, of any insurance organization or company, necessary
for the maintenance of reasonable fire and public liability insurance covering
requirements pertaining to said Premises.

15. LIENS Tenant shall keep the Premises free from any liens arising out of any
work performed, materials furnished or obligation incurred by Tenant. In the
event that Tenant shall not, within ten (10) days following the imposition of
such lien, cause the same to be released of record, Landlord shall have, in
addition to all other remedies provided herein and by law, the right, but no
obligation, to cause the same to be released by such means as it shall deem
proper, including payment of the claim giving rise to such lien. All sums paid
by Landlord for such purpose, and all expenses incurred by it in connection
therewith, shall be payable to Landlord by Tenant on demand with interest at
the prime rate of interest as quoted by the Bank of America.

16. ASSIGNMENT AND SUBLETTING   Tenant shall not assign, transfer, or
hypothecate the leasehold  estate under this Lease, or any interest therein, and
shall not sublet the Premises, or any part thereof, or any right or privilege
appurtenant thereto, or suffer any other person or entity to occupy or use the
Premises, or any portion thereof, without, in each case, the prior written
consent of Landlord which consent will not be unreasonably withheld.  As a
condition for granting this consent to any assignment, transfer, or subletting,
Landlord shall require Tenant to pay to Landlord, as Additional Rent, all rents
and/or additional consideration due Tenant from its assignees, transferees, or
subtenants in excess of the Rent payable by Tenant to Landlord hereunder for the
assigned, transferred and/or subleased space.  Tenant shall, by thirty (30) days
written notice, advise Landlord of its intent to assign or transfer Tenant's
interest in the Lease or sublet the Premises or any portion thereof for any part
of the term hereof.  Within thirty (30) days after receipt of said written
notice, Landlord may, in its sole discretion, elect to terminate this Lease as
to the portion of the Premises described in Tenant's notice on the date
specified in Tenant's notice by giving written notice of such election
terminate. Notwithstanding the above, Landlord shall not have a right to
terminate said Lease as related to a sublease unless Tenant subleases more than
thirty percent (30%) of the entire Leased Premises. If no such notice to
terminate is given to Tenant with said thirty (30) day period, tenant may
proceed to locate an acceptable sublessee, assignee, or other transferee for
presentment to Landlord for Landlord's approval, all in accordance with the
terms, covenants, and conditions of this paragraph 16. If Tenant intends to
sublet the entire Premises and Landlord elects to terminate this Lease, this
Lease shall be terminated on the date specified in Tenant's notice. If, however,
this Lease shall terminate pursuant to the foregoing with respect to less than
all the Premises, the rent, as defined and reserved hereinabove shall be
adjusted on a pro rata basis to the number of square feet retained by Tenant,
and this Lease as so amended shall continue in full force and effect. In the
event Tenant is allowed to assign, transfer or sublet the whole or any part of
the Premises, with the prior written

                                       4
<PAGE>

consent of Landlord, no assignee, transferee or subtenant shall assign or
transfer this Lease, either in whole or in part, or sublet the whole or any part
of the Premises, without also having obtained the prior written consent of
Landlord. A consent of Landlord to one assignment, transfer, hypothecation,
subletting, occupation or use by any other person shall not release Tenant from
any of Tenant's obligations hereunder or be deemed to be a consent to any
subsequent similar or dissimilar assignment, transfer, hypothecation,
subletting, occupation or use by any other person. Any such assignment,
transfer, hypothecation, subletting, occupation or use without such consent
shall be void and shall constitute a breach of this Lease by Tenant and shall,
at the option of Landlord exercised by written notice to Tenant, terminate this
Lease. The leasehold estate under this Lease shall not, nor shall any interest
therein, be assignable for any purpose by operation of law without the written
consent of Landlord. As a condition to its consent, Landlord shall require
Tenant to pay all expenses in connection with the assignment, and Landlord shall
require Tenant's assignee to transferee (or other assignees or transferees) to
assume in writing all of the obligations under this Lease and for Tenant to
remain liable to Landlord under the Lease. Notwithstanding the above, in no
event will Landlord consent to a sub-sublease.

17. SUBORDINATION AND MORTGAGES In the event Landlord's title or leasehold
interest is now or hereafter encumbered by a deed of trust, upon the interest of
Landlord in the land and buildings in which the demised Premises are located, to
secure a loan from a lender (hereinafter referred to as "Lender") to Landlord,
Tenant shall, at the request of Landlord or Lender, execute in writing an
agreement subordinating its rights under this Lease to the lien of such deed of
trust, or, if so requested, agreeing that the lien of Lender's deed of trust
shall be or remain subject and subordinate to the rights of Tenant under this
Lease provided that such Lender shall execute a "Non-Disturbance" agreement
reasonably acceptable to Tenant. Notwithstanding any such subordination,
Tenant's possession under this Lease shall not be disturbed if Tenant is not in
default and so long as Tenant shall pay all rent and observe and perform all of
the provisions set forth in this Lease.

18. ENTRY BY LANDLORD Landlord reserves, and shall at all reasonable times after
at least 24 hours notice (except in emergencies) have, the right to enter the
Premises to inspect them; to perform any services to be provided by Landlord
hereunder; to make repairs or provide any services to a contiguous tenant(s); to
submit the Premises to prospective purchasers, mortgagers or tenants; to post
notices of nonresponsibility; and to alter, improve or repair the Premises or
other parts of the building, all without abatement of rent, and may erect
scaffolding and other necessary structures in or through the Premises where
reasonably required by the character of the work to be performed; provided,
however that the business of Tenant shall be interfered with to the least extent
that is reasonably practical. Any entry to the Premises by Landlord for the
purposes provided for herein shall not under any circumstances be construed or
deemed to be a forcible or unlawful entry into or a detainer of the Premises or
an eviction, actual or constructive, of Tenant from the Premises or any portion
thereof.

19. BANKRUPTCY AND DEFAULT The commencement of a bankruptcy action or
liquidation action or reorganization action or insolvency action or an
assignment of or by Tenant for the benefit of creditors, or any similar action
undertaken by Tenant, or the insolvency of Tenant, shall, at Landlord's option,
constitute a breach of this Lease by Tenant. If the trustee or receiver
appointed to serve during a bankruptcy, liquidation, reorganization, insolvency
or similar action elects to reject Tenant's unexpired Lease, the trustee or
receiver shall notify Landlord in writing of its election within thirty (30)
days after an order for relief in a liquidation action or within thirty (30)
days after the commencement of any action.

   Within thirty (30) days after court approval of the assumption of this Lease,
the trustee or receiver shall cure (or provide adequate assurance to the
reasonable satisfaction of Landlord that the trustee or receiver shall cure) any
and all previous defaults under the unexpired Lease and shall compensate
Landlord for all actual pecuniary loss and shall provide adequate assurance of
future performance under said Lease to the reasonable satisfaction of Landlord.
Adequate assurance of future performance, as used herein, includes, but shall
not be limited to: (i) assurance of source and payment of rent, and other
consideration due under this Lease; (ii) assurance that the assumption or
assignment of this Lease will not breach substantially any provision, such as
radius, location, use, or exclusivity provision, in any agreement relating to
the above described Premises.

   Nothing contained in this section shall affect the existing right of Landlord
to refuse to accept an assignment upon commencement of or in connection with a
bankruptcy, liquidation, reorganization or insolvency action or an assignment of
Tenant for the benefit of creditors or other similar act. Nothing contained in
this Lease shall be construed as giving or granting or creating an equity in the
demised Premises to Tenant. In no event shall the leasehold estate under this
Lease. or any interest therein, be assigned by voluntary or involuntary
bankruptcy proceeding without the prior written consent of Landlord. In no event
shall this Lease or any rights or privileges hereunder be an asset of Tenant
under any bankruptcy, insolvency or reorganization proceedings.

   The failure to perform or honor any covenant, condition or representation
made under this Lease shall constitute a default hereunder by Tenant upon
expiration of the appropriate grace period hereinafter provided. Tenant shall
have a period of five (5) days from the date of written notice from Landlord
within which to cure any default in the payment of rental or adjustment thereto.
Tenant shall have a period of thirty (30) days from the date of written notice
from Landlord within which to cure any other default under this Lease. Upon an
uncured default of this Lease by Tenant, Landlord shall have the following
rights and remedies in addition to any other rights or remedies available to
Landlord at law or in equity:

   (a) The rights and remedies provided for by California Civil Code Section
1951.2, including but not limited to, recovery of 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 rental loss for the same period that Tenant
proves could be reasonably avoided, as computed pursuant to subsection (b) of
said Section 1951.2. Any proof by Tenant under subparagraphs (2) and (3) of
Section 1951.2 of the California Civil Code of the amount of rental loss that
could be reasonably avoided shall be made in the following manner: Landlord and
Tenant shall each select a licensed real estate broker in the business of
renting property of the same type and use as the Premises and in the same
geographic vicinity. Such two real estate brokers shall select a third licensed
real estate broker, and the three licensed real estate brokers so selected shall
determine the amount of the rental loss that could be reasonably avoided from
the balance of the term of this Lease after the time of award. The decision of
the majority of said licensed real estate brokers shall be final and binding
upon the parties hereto.

   (b) The rights and remedies provided by California Civil Code Section which
allows Landlord to continue the Lease in effect and to enforce all of its rights
and remedies under this Lease, including the right to recover rent as it becomes
due, for so long as Landlord does not terminate Tenant's right to possession;
acts of maintenance or preservation, efforts to relet the Premises, or the
appointment of a receiver upon Landlord's initiative to protect its interest
under this Lease shall not constitute a termination of Tenant's right to
possession.

   (c) The right to terminate this Lease by giving notice to Tenant in
accordance with applicable law.

   (d) To the extent permitted by law, the right and power, to enter the
Premises and remove therefrom all persons and property, to store such property
in a public warehouse or elsewhere at the cost of and for the account of Tenant,
and to sell such property and apply such proceeds therefrom pursuant to
applicable California law. Landlord, may from time to time sublet the Premises
or any part thereof for such term or terms (which may extend beyond the term of
this Lease) and at such rent and such other terms as Landlord in its reasonable
sole discretion may deem advisable, with the right to make alterations and
repairs to the Premises. Upon each subletting, (i) Tenant shall be immediately
liable to pay Landlord, in addition to indebtedness other than rent due
hereunder, the reasonable cost of such subletting, including, but not limited
to, reasonable attorneys' fees, and any real estate commissions actually paid,
and the cost of such reasonable alterations and repairs incurred by Landlord and
the amount, if any, by which the rent hereunder for the period of such
subletting(to the extent such period does not exceed the term hereof) exceeds
the amount to be paid as rent for the Premises for such period or (ii) at the
option of Landlord, rents received from such subletting shall be applied first
to payment of indebtedness other than rent due hereunder from Tenant to
Landlord; second, to the payment of any costs of such subletting and of such
alterations and repairs; third to payment of rent due and unpaid hereunder; and
the residue, if any, shall be held by Landlord and applied in payment of future
rent as the same becomes due hereunder. If Tenant has been credited with any
rent to be received by such subletting under option (i) and such rent shall not
be promptly paid to Landlord by the subtenant(s), or if such rentals received
from such subletting under option (ii) during any month be less than that to be
paid during that month by Tenant hereunder, Tenant shall pay any such deficiency
to Landlord. Such deficiency shall be calculated and paid monthly. No taking
possession of the Premises by Landlord, shall be construed as an election on its
part to terminate this Lease unless a written notice of such intention be given
to Tenant. Notwithstanding any such subletting without termination, Landlord may
at any time hereafter elect to terminate this Lease for such previous breach.

   (e) The right to have a receiver appointed for Tenant upon application by
Landlord, to take possession of the Premises and to apply any rental
collected from the Premises and to exercise all other rights and remedies
granted to Landlord pursuant to subparagraph d above.

 20. ABANDONMENT Tenant shall not vacate or abandon the Premises at any time
during the term of this Lease and if Tenant shall abandon, vacate or surrender
said Premises, or be dispossessed by the process of law, or otherwise, any
personal property belonging to Tenant and left on the Premises shall be deemed
to be abandoned, at the option of Landlord, except such property as may be
mortgaged to Landlord.

 21. DESTRUCTION In the event the Premises are destroyed in whole or in part
from any cause, except for routine maintenance and repairs and incidental

                                       5
<PAGE>

 damage and destruction caused from vandalism and accidents for which Tenant is
 responsible under Paragraph 7, Landlord may, at its option:

   (a) Rebuild or restore the Premises to their condition prior to the damage or
 destruction, or
   (b) Terminate this Lease. (providing that the Premises is damaged to the
 extent of 33 1/3% of the replacement cost)

   If Landlord does not give Tenant notice in writing within thirty (30) days
 from the destruction of the Premises of its election to either rebuild and
 restore them, or to terminate this Lease, Landlord shall be deemed to have
 elected to rebuild or restore them, in which event Landlord agrees, at its
 expense except for any deductible, which is the responsibility of Tenant,
 promptly to rebuild or restore the Premises to their condition prior to the
 damage or destruction. Tenant shall be entitled to a reduction in rent while
 such repair is being made in the proportion that the area of the Premises
 rendered untenantable by such damage bears to the total area of the Premises.
 If Landlord initially reasonably estimates that the rebuilding or restoration
 will exceed 180 days, or if the damage occurs during the last six months of the
 initial Term and the restoration will exceed 30 days, or if Landlord does not
 complete the rebuilding or restoration within one hundred eighty (180) days
 following the date of destruction (such period of time to be extended for
 delays caused by the fault or neglect of Tenant or because of Acts of God, acts
 of public agencies, labor disputes, strikes, fires, freight embargos, rainy or
 stormy weather, inability to obtain materials, supplies or fuels, acts of
 contractors or subcontractors, or delay of the contractors or subcontractors
 due to such causes or other contingencies beyond the control of Landlord), then
 Tenant shall have the right to terminate this Lease by giving fifteen (15) days
 prior written notice to Landlord. Notwithstanding anything herein to the
 contrary, Landlord's obligation to rebuild or restore shall be limited to the
 building and interior improvements constructed by Landlord as they existed as
 of the commencement date of the Lease and shall not include restoration of
 Tenant's trade fixtures, equipment, merchandise, or any improvements,
 alterations or additions made by Tenant to the Premises, which Tenant shall
 forthwith replace or fully repair at Tenant's sole cost and expense provided
 this Lease is not cancelled according to the provisions above.

   Unless this Lease is terminated pursuant to the foregoing provisions, this
 Lease shall remain in full force and effect. Tenant hereby expressly waives the
 provisions of Section 1932, Subdivision 2, in Section 1933, Subdivision 4 of
 the California Civil Code.

   In the event that the building in which the Premises are situated is damaged
 or destroyed to the extent of not less than 33 1/3% of the replacement cost
 thereof, Landlord may elect to terminate this Lease, whether the Premises be
 injured or not. Notwithstanding anything to the contrary herein, Landlord may
 terminate this Lease in the event of an uninsured event or if insurance
 proceeds are insufficient to cover one hundred percent of the rebuilding costs
 net of the deductible provided, however, Tenant shall have the right, in its
 discretion, to contribute such excess funds (within 30 days of Tenant's receipt
 of an invoice from Landlord) to permit Landlord to repair the Premises.

 22. EMINENT DOMAIN If all or any part of the Premises shall be taken by any
 public or quasi-public authority under the power of eminent domain or
 conveyance in lieu thereof, this Lease shall terminate as to any portion of the
 Premises so taken or conveyed on the date when title vests to the condemnor,
 and Landlord shall be entitled to any and all payment, income, rent, award, or
 any interest therein whatsoever which may be paid or made in connection with
 such taking or conveyance, and Tenant shall have no claim against Landlord or
 otherwise for the value of any unexpired term of this Lease. Notwithstanding
 the foregoing paragraph, any compensation specifically awarded Tenant for loss
 of business, Tenant's personal property, moving cost or loss of goodwill, shall
 be and remain the property of Tenant.

   If any action or proceeding is commenced for such taking of the Premises or
 any part thereof, or if Landlord is advised in writing by any entity or body
 having the right or power of condemnation of its intention to condemn the
 premises or any portion thereof, then Landlord shall have the right to
 terminate this Lease by giving Tenant written notice thereof within sixty (60)
 days of the date of receipt of said written advice, or commencement of said
 action or proceeding, or taking conveyance, which termination shall take place
 as of the first to occur of the last day of the calendar month next following
 the month in which such notice is given or the date on which title to the
 Premises shall vest in the condemnor.

   In the event of such a partial taking or conveyance of the Premises, if the
 portion of the Premises taken or conveyed is so substantial that the Tenant can
 no longer reasonably conduct its business in the manner prior to the taking,
 Tenant shall have the privilege of terminating this Lease within sixty (60)
 days from the date of such taking or conveyance, upon written notice to
 Landlord of its intention so to do, and upon giving of such notice this Lease
 shall terminate on the last day of the calendar month next following the month
 in which such notice is given, upon payment by Tenant of the rent from the date
 of such taking or conveyance to the date of termination.

   If a portion of the Premises be taken by condemnation or conveyance in lieu
 thereof and neither Landlord nor Tenant shall terminate this Lease as provided
 herein, this Lease shall continue in full force and effect as to the part of
 the Premises not so taken or conveyed, and the rent herein shall be apportioned
 as of the date of such taking or conveyance so that thereafter the rent to be
 paid by Tenant shall be in the ratio that the area of the portion of the
 Premises not so taken or conveyed bears to the total area of the Premises prior
 to such taking.

 23. SALE OR CONVEYANCE BY LANDLORD In the event of a sale or conveyance of the
 Premises or any interest therein, by any owner of the reversion then
 constituting Landlord upon assumption in writing of Landlord's obligations
 under this Lease by the transferee, the transferor shall thereby be released
 from any further liability upon any of the terms, covenants or conditions
 (express or implied) herein contained in favor of Tenant, and in such event,
 insofar as such transfer is concerned, Tenant agrees to look solely to the
 responsibility of the successor in interest of such transferor in and to the
 Premises and this Lease. This Lease shall not be affected by any such sale or
 conveyance, and Tenant agrees to attorn to the successor in interest of such
 transferor.

 24. ATTORNMENT TO LENDER OR THIRD PARTY In the event the interest of Landlord
 in the land and buildings in which the leased Premises are located (whether
 such interest of Landlord is a fee title interest or a leasehold interest) is
 encumbered by deed of trust, and such interest is acquired by the lender or any
 third party through judicial foreclosure or by exercise of a power of sale at
 private trustee's foreclosure sale provided that such Lender or third party had
 executed a "Non-Disturbance Agreement" with Tenant in accordance with Paragraph
 17 hereto, Tenant hereby agrees to attorn to the purchaser at any such
 foreclosure sale and to recognize Such purchaser as the Landlord under this
 Lease. In the event the lien of the deed of trust securing the loan from a
 Lender to Landlord is prior and paramount to the Lease, this Lease shall
 nonetheless continue in full force and effect for the remainder of the
 unexpired term hereof, at the same rental herein reserved and upon all the
 other terms, conditions and covenants herein contained.

 25. HOLDING OVER Any holding over by Tenant after expiration or other
 termination of the term of this Lease with the written consent of Landlord
 delivered to Tenant shall not constitute a renewal or extension of the Lease or
 give Tenant any rights in or to the leased Premises except as expressly
 provided in this Lease. Any holding over after the expiration or other
 termination of the term of this Lease, with the consent of Landlord, shall be
 construed to be a tenancy from month to month, on the same terms and conditions
 herein specified insofar as applicable except that the monthly Basic Rent shall
 be increased to an amount equal to one hundred fifty (150%) percent of the
 monthly Basic Rent required during the last month of the Lease term.

 26. CERTIFICATE OF ESTOPPEL Tenant shall at any time upon not less than ten
 (10) days prior written notice from Landlord execute, acknowledge and deliver
 to Landlord a statement in writing (i) certifying that this Lease is unmodified
 and in full force and effect (or, if modified, stating the nature of such
 modification and certifying that this Lease, as so modified, is in full force
 and effect) and the date to which the rent and other charges are paid in
 advance, if any, and (ii) acknowledging that there are not, to Tenant's
 knowledge, any uncured defaults on the part of Landlord hereunder, or
 specifying such defaults, if any, are claimed. Any such statement may be
 conclusively relied upon by any prospective purchaser or encumbrancer of the
 Premises. Tenant's failure to deliver such statement within such time shall be
 conclusive upon Tenant that this Lease is in full force and effect, without
 modification except as may be represented by Landlord; that there are no
 uncured defaults in Landlord's performance, and that not more than one month's
 rent has been paid in advance.

 27. CONSTRUCTION CHANGES It is understood that the description of the Premises
 and the location of ductwork, plumbing and other facilities therein are subject
 to such minor changes as Landlord or Landlord's architect determines to be
 desirable in the course of construction of the Premises, and no such changes
 shall affect this Lease or entitle Tenant to any reduction of rent hereunder or
 result in any liability of Landlord to Tenant. Landlord does not guarantee the
 accuracy of any drawings supplied to Tenant and verification of the accuracy of
 such drawings rests with Tenant.

 28. RIGHT OF LANDLORD TO PERFORM All terms, covenants and conditions of this
 Lease to be performed or observed by Tenant shall performed or observed by
 Tenant at Tenant's sole cost and expense and without any reduction of rent. If
 Tenant shall fail to pay any sum of money, or other rent, required to be paid
 by it hereunder and such failure shall continue for five (5) days after written
 notice by Landlord, or shall fail to perform any other term or covenant
 hereunder on its part to be performed, and such failure shall continue for
 thirty (30) days after written notice thereof by Landlord, Landlord, without
 waiving or releasing Tenant from any obligation of Tenant hereunder, may, but
 shall not be obliged to, make any such payment or perform any such other term
 or covenant on Tenant's part to be performed. All sums so paid by Landlord and
 all necessary costs of such performance by Landlord together with interest
 thereon at the rate of the prime rate of interest per annum as quoted by the
 Bank of America from the date of such payment on performance by Landlord, shall
 be paid (and Tenant covenants to make such payment) to Landlord on demand by
 Landlord, and Landlord shall have (in addition to any other right or remedy of
 Landlord) the same rights and remedies in the event of nonpayment by Tenant as
 in the case of failure by Tenant in the payment of rent hereunder.

 29. ATTORNEYS' FEES

   A. In the event that either Landlord or Tenant should bring suit for the
 possession of the Premises, for the recovery of any sum due under this Lease,
 or because of the breach of any provision of this Lease, or for any other
 relief against the other party hereunder, then all costs and expenses,
 including reasonable attorneys' fees,

                                       6

 which obligation on the part of the other party shall be deemed to have accrued
 on the date of the commencement of such action and shall be enforceable whether
 or not the action is prosecuted to judgment.

   B. Should Landlord be named as a defendant in any suit brought against Tenant
 in connection with or arising out of Tenant's occupancy hereunder, Tenant shall
 pay to Landlord its costs and expenses incurred in such suit, including a
 reasonable attorney's fee.

 30. WAIVER The waiver by either party of the other party's failure to perform
 or observe any term, covenant or condition herein contained to be performed or
 observed by such waiving party shall not be deemed to be a waiver of such term,
 covenant or condition or of any subsequent failure of the party failing to
 perform or observe the same or any other such term, covenant or condition
 therein contained, and no custom or practice which may develop between the
 parties hereto during the term hereof shall be deemed a waiver of, or in any
 way affect, the right of either party to insist upon performance and observance
 by the other party in strict accordance with the terms hereof.

 31. NOTICES All notices, demands, requests, advices or designations which may
 be or are required to be given by either party to the other hereunder shall be
 in writing. All notices, demands, requests, advices or designations by Landlord
 to Tenant shall be sufficiently given, made or delivered if personally served
 on Tenant by leaving the same at the Premises of if sent by United Stated
 certified or registered mail, postage prepaid, addressed to Tenant at the
 Premises. All notices, demands, requests, advices or designations by Tenant to
 Landlord shall be sent by United States certified or registered mail, postage
 prepaid, addressed to Landlord at its offices at   A&P Foundations, 2560

 -------------------------------------------------------
 Each notice, request, demand, advice or designation referred to in this
 paragraph shall be deemed received on the date of the personal service or
 mailing thereof in the manner herein provided, as the case may be.

 32. EXAMINATION OF LEASE Submission of this instrument for examination or
 signature by Tenant does not constitute a reservation of or option for a lease,
 and this instrument is not effective as a lease or otherwise until its
 execution and delivery by both Landlord and Tenant.

 33. DEFAULT BY LANDLORD Landlord shall not be in default unless Landlord fails
 to perform obligations required of Landlord within a reasonable time, but in no
 event earlier than (30) days after written notice by Tenant to Landlord and to
 the holder of any first mortgage or deed of trust covering the Premises whose
 name and address shall have heretofore been furnished to Tenant in writing,
 specifying wherein Landlord has failed to perform such obligations; provided,
 however, that if the nature of Landlord's obligations is such that more than
 thirty (30) days are required for performance, then Landlord shall not be in
 default if Landlord commences performance within such thirty (30) day period
 and thereafter diligently prosecutes the same to completion.

 34. CORPORATE AUTHORITY If Tenant is a corporation (or a partnership), each
 individual executing this Lease on behalf of said corporation (or partnership)
 represents and warrants that he is duly authorized to execute and deliver this
 Lease on behalf of said corporation (or partnership) in accordance with the by-
 laws of said corporation (or partnership in accordance with the partnership
 agreement) and that this Lease is binding upon said corporation (or
 partnership) in accordance with its terms. If Tenant is a corporation, Tenant
 shall, within thirty (30) days after execution of this Lease, deliver to
 Landlord a certified copy of the resolution of the Board of Directors of said
 corporation authorizing or ratifying the execution of this Lease.

 35. [DELETED]

                                       11
<PAGE>

representatives and/or invitees shall not use any parking spaces other than

45.   ASSESSMENT CREDITS: The demised property herein may be subject to a
      ------------------
special assessment levied by the City of Sunnyvale as part of an Improvement
District. As a part of said special assessment proceedings (if any), additional
bonds were or may be sold and assessments were or may be levied to provide for
construction contingencies and reserve funds. Interest shall be earned on such
funds created for contingencies and on reserve funds which will be credited for
the benefit of said assessment district. To the extent surpluses are created in
said district through unused contingency funds, interest earnings or reserve
funds, such surpluses shall be deemed the property of Landlord, Notwithstanding
that such surpluses may be credited on assessments otherwise due against the
Leased Premises, Tenant shall pay to Landlord, as additional rent if, and at the
time of any such credit of surpluses, an amount equal to all such surpluses so
credited. For example: if (i) the property is subject to an annual assessment of
$1,000.00, and (ii) a surplus of $200.00 is credited towards the current year's
assessment which reduces the assessment amount shown on the property tax bill
from $1,000.00 to $800.00, Tenant shall, upon receipt of notice from Landlord,
pay to Landlord said $200.00 credit as Additional Rent.

46.   ASSIGNMENT AND SUBLETTING (CONTINUED):
      -------------------------------------

     A.  Notwithstanding the foregoing, Landlord and Tenant agree that it shall
not be unreasonable for Landlord to refuse to consent to a proposed assignment,
sublease or other transfer ("Proposed Transfer") if the Premises or ant other
portion of the Property would become subject to additional or different
Government Requirements as a direct or indirect consequence of the Proposed
Transfer and/or the Proposed Transferee's use and occupancy of the Premises and
the Property. However, Landlord may, in its sole discretion, consent to such a
Proposed Transfer where Landlord is indemnified by Tenant and (i) Subtenant or
(ii) Assignee, in form and substance satisfactory to Landlord's counsel, by
Tenant and/or the Proposed Transferee from and against any and all costs,
expenses, obligations and liability arising out of the Proposed Transfer and/or
the Proposed Transferee's use and occupancy of the Premises and the Property.

     B.  Any and all sublease agreement(s) between Tenant and any and all
subtenant(s) (which agreements must be consented to by Landlord, pursuant to the
requirements of this Lease) shall contain the following language:

  "If Landlord and Tenant jointly and voluntarily elect, for any reason
whatsoever, to terminate the Master Lease prior to the scheduled Master Lease
termination date, then this Sublease (if then still in effect) shall terminate
concurrently with the termination of the Master Lease. Subtenant expressly
acknowledges and agrees that (1) the voluntary termination of the Master Lease
by Landlord and Tenant and the resulting termination of this Sublease shall not
give Subtenant any right or power to make any legal or equitable claim against
Landlord, including without limitation any claim for interference with contract
or interference with prospective economic advantage, and (2) Subtenant hereby
waives any and all rights it may have under law or at equity against Landlord to
challenge such an early termination of the

                                       12
<PAGE>

Sublease, and unconditionally releases and relieves Landlord, and its officers,
directors, employees and agents, from any and all claims, demands, and/or causes
of action whatsoever (collectively, "Claims"), whether such matters are known or
unknown, latent or apparent, suspected or unsuspected, foreseeable or
unforeseeable, which Subtenant may have arising out of or in connection with any
such early termination of this Sublease. Subtenant knowingly and intentionally
waives any and all protection which is or may be given by Section 1542 of the
California Civil Code which provides as follows: "A general release does not
extend to claims which the creditor does not know or suspect to exist in his
favor at the time of executing the release, which if known by him must have
materially affected his settlement with debtor.

     The term of this Sublease is therefore subject to early termination.
Subtenant's initials here below evidence (a) Subtenant's consideration of and
agreement to this early termination provision, (b) Subtenant's acknowledgment
that, in determining the net benefits to be derived by Subtenant under the terms
of this Sublease, Subtenant has anticipated the potential for early termination,
and (c) Subtenant's agreement to the general waiver and release of Claims above.

47.  BANKRUPTCY AND DEFAULT: Paragraph 19 is modified to provide that with
     ----------------------
respect to non-monetary defaults not involving Tenant's failure to pay Basic
Rent or Additional Rent, Tenant shall not be in default of any non-monetary
obligation if (i) more than thirty (30) days is required to cure such non-
monetary default, and (ii) Tenant commences cure of such default as soon as
reasonably practicable after receiving written notice of such default from
Landlord and thereafter continuously and with due diligence prosecutes such cure
to completion.

48.  ABANDONMENT: Paragraph 20 is modified to provide that Tenant shall not be
     -----------
in default under the Lease if it leaves all or any part of Premises vacant so
long as (i) Tenant is performing all of its other obligations under the Lease
including the obligation to pay Basic Rent and Additional Rent (ii) Tenant
provides on-site security during normal business hours for those parts of the
Premises left vacant, (iii) such vacancy does not materially and adversely
affect the validity or coverage of any policy of insurance carried by Landlord
with respect to the Premises, and (iv) the utilities and heating and ventilation
system are operated and maintained to the extent necessary to prevent damage to

49.  HAZARDOUS MATERIALS: Landlord and Tenant agree as follows with respect to
     -------------------
the existence or use of "Hazardous Materials" (as defined herein) on, in, under
or about the Premises and real property located beneath said Premises and the
common areas of the Parcel, which includes the entire parcel of land on which
the Premises are located as shown in Green on Exhibit A attached hereto
                                              ---------
(hereinafter collectively referred to as the "Property"):

     A.  As used herein, the term "Hazardous Materials" shall mean any material,
waste, chemical, mixture or byproduct which is or hereafter is defined, listed
or designated under Environmental Laws (defined below) as a pollutant, or as a
contaminant, or as a toxic or hazardous substance, waste or material, or any
other unwholesome, hazardous, toxic, biohazardous, or radioactive material,
waste, chemical, mixture or byproduct, or which is listed, regulated or
restricted by any Environmental Law (including, without limitation, petroleum
hydrocarbons or any distillates or derivatives or fractions thereof,
polychlorinated biphenyls, or asbestos). As used herein, the term "Environmental
Laws" shall mean any applicable Federal, State of California or local government
law (including common law), statute, regulation, rule, ordinance, permit,
license, order, requirement, agreement, or approval, or any determination,
judgment, directive, or order of any executive or judicial authority at any
level of Federal, State of California or local government (whether now existing
or subsequently adopted or promulgated) relating to pollution or the protection
of the environment, ecology, natural resources, or public health and safety.

     B.  Tenant shall obtain Landlord's written consent, which may be withheld
in Landlord's discretion, prior to the occurrence of any Tenant's Hazardous
Materials Activities

                                       13
<PAGE>

(defined below); provided, however, that Landlord's consent shall not be
required for normal use in compliance with applicable Environmental Laws of
customary household and office supplies (Tenant shall first provide Landlord
with a list of said materials use), such as mild cleaners, lubricants and copier
toner. As used herein, the term "Tenant's Hazardous Materials Activities" shall
mean any and all use, handling, generation, storage, disposal, treatment,
transportation, release, discharge, or emission of any Hazardous Materials on,
in, beneath, to, from, at or about the Property, in connection with Tenant's use
of the Property, or by Tenant or by any of Tenant's agents, employees,
contractors, vendors, invitees, visitors or its future subtenants or assignees.
Tenant agrees that any and all Tenant's Hazardous Materials Activities shall be
conducted in strict, full compliance with applicable Environmental Laws at
Tenant's expense, and shall not result in any contamination of the Property or
the environment. Tenant agrees to provide Landlord with prompt written notice of
any spill or release of Hazardous Materials at the Property during the term of
the Lease of which Tenant becomes aware, and further agrees to provide Landlord
with prompt written notice of any violation of Environmental Laws in connection
with Tenant's Hazardous Materials Activities of which Tenant becomes aware. If
Tenant's Hazardous Materials Activities involve Hazardous Materials other than
normal use of customary household and office supplies, Tenant also agrees at
Tenant's expense: (i) to install such Hazardous Materials monitoring, storage
and containment devices as Landlord reasonably deems necessary (Landlord shall
have no obligation to evaluate the need for any such installation or to require
any such installation); (ii) provide Landlord with a written inventory of such
Hazardous Materials, including an update of same each year upon the anniversary
date of the Commencement Date of the Lease ("Anniversary Date"); and (iii) on
each Anniversary Date, to retain a qualified environmental consultant,
acceptable to Landlord, to evaluate whether Tenant is in compliance with all
applicable Environmental Laws with respect to Tenant's Hazardous Materials
Activities. Tenant, at its expense, shall submit to Landlord a report from such
environmental consultant which discusses the environmental consultant's findings
within two (2) months of each Anniversary Date. Tenant, at its expense, shall
promptly undertake and complete any and all steps necessary, and in full
compliance with applicable Environmental Laws, to fully correct any and all
problems or deficiencies identified by the environmental consultant, and
promptly provide Landlord with documentation of all such corrections.

     C.  Prior to termination or expiration of the Lease, Tenant, at its
expense, shall (i) properly remove from the Property all Hazardous Materials
which come to be located at the Property in connection with Tenant's Hazardous
Materials Activities, and (ii) fully comply with and complete all facility
closure requirements of applicable Environmental Laws regarding Tenant's
Hazardous Materials Activities, including but not limited to (x) properly
restoring and repairing the Property to the extent damaged by such closure
activities, and (y) obtaining from the local Fire Department or other
appropriate governmental authority with jurisdiction a written concurrence that
closure has been completed in compliance with applicable Environmental Laws.
Tenant shall promptly provide Landlord with copies of any claims, notices, work
plans, data and reports prepared, received or submitted in connection with any
such closure activities.

     D.  If Landlord, in its sole discretion, believes that the Property has
become contaminated as a result of Tenant's Hazardous Materials Activities,
Landlord in addition to any other rights it may have under this Lease or under
Environmental Laws or other laws, may enter upon the Property and conduct
inspection, sampling and analysis, including but not limited to obtaining and
analyzing samples of soil and groundwater, for the purpose of determining the
nature and extent of such contamination. Tenant shall promptly reimburse
Landlord for the costs of such an investigation, including but not limited to
reasonable attorneys' fees Landlord incurs with respect to such investigation,
that discloses Hazardous Materials contamination for which Tenant is liable
under this Lease. Notwithstanding the above, Landlord may, at its option and in
its sole and absolute discretion, choose to perform remediation and obtain
reimbursement for cleanup costs as set forth herein from Tenant. Any cleanup
costs incurred by Landlord as the result of Tenant's Hazardous Materials
Activities shall be reimbursed by Tenant within thirty (30) days of presentation
of written documentation of the expense to Tenant by Landlord. Such reimbursable
costs shall include, but not be limited to, any reasonable consultant and
attorney fees incurred by Landlord. Tenant shall take all actions necessary to
preserve any claims it has against third parties, including, but not limited
to, its insurers, for claims related to its operation, management of Hazardous
Materials or contamination of the Property. Except as may be required of Tenant
by applicable Environmental Laws, Tenant shall not perform any sampling,
testing, or drilling to identify the presence of any Hazardous Materials at the
Property, without Landlord's prior written consent which may be withheld in
Landlord's discretion. Tenant shall promptly provide Landlord with copies of any
claims, notices, work plans, data and reports prepared, received or submitted in
connection with any sampling, testing or drilling performed pursuant to the
preceding sentence.

                                       14

E.  Tenant shall indemnify, defend (with legal counsel acceptable to Landlord,
whose consent shall not unreasonably be withheld) and hold harmless Landlord,
its employees, assigns, successors, successors-in-interest, agents and
representatives from and against any and all claims (including but not limited
to third party claims from a private party or a government authority),
liabilities, obligations, losses, causes of action, demands, governmental
proceedings or directives, fines, penalties, expenses, costs (including but not
limited to reasonable attorneys', consultants' and other experts' fees and
costs), and damages, which arise from or relate to: (i) Tenant's Hazardous
Materials Activities; (ii) any Hazardous Materials contamination caused by
Tenant prior to the Commencement Date of the Lease; or (iii) the breach of any
obligation of Tenant under this Paragraph 49 (collectively, "Tenant's
Environmental Indemnification"). Tenant's Environmental Indemnification shall
include but is not limited to the obligation to promptly and fully reimburse
Landlord for losses in or reductions to rental income, and diminution in fair
market value of the Property. Tenant's Environmental Indemnification shall
further include but is not limited to the obligation to diligently and properly
implement to completion, at Tenant's expense, any and all environmental
investigation, removal, remediation, monitoring, reporting, closure activities,
or other environmental response action (collectively, "Response Actions").
Tenant shall promptly provide Landlord with copies of any claims, notices, work
plans, data and reports prepared, received or submitted in connection with any
Response Actions.

It is agreed that the Tenant's responsibilities related to Hazardous Materials
will survive the expiration or termination of this Lease and that Landlord may
obtain specific performance of Tenant's responsibilities under this Paragraph
49.

50.  CONSENT: Whenever the consent of one party to the other is required
     -------
hereunder, such consent shall not be unreasonably withheld.

51.  AUTHORITY TO EXECUTE: The parties executing this Lease Agreement hereby
     --------------------
warrant and represent that they are properly authorized to execute this Lease
Agreement and bind the parties on behalf of whom they execute this Lease
Agreement and to all of the terms, covenants and conditions of this Lease
Agreement as they relate to the respective parties hereto.

52.  PUNCH LIST: In addition to and notwithstanding anything to the contrary in
     ----------
Paragraphs 5 and 40 of this Lease, Tenant shall have thirty (30) days after the
Commencement Date to provide Landlord with a written "punch list" pertaining to
defects in the interior improvements constructed by Landlord for Tenant. As soon
as reasonably possible thereafter, Landlord, or one of Landlord's
representatives (if so approved by Landlord), and Tenant shall conduct a joint
walk-through of the Premises (if Landlord so requires), and inspect such Tenant
Improvements, using their best efforts to agree on the incomplete or defective
construction related to the Tenant Improvements installed for Tenant by
Landlord. After such inspection has been completed, Landlord shall prepare, mid
both parties shall sign, a list of all "punch list" items which the parties
reasonably agree are (i) to be corrected by Landlord (but which shall exclude
any damage or defects caused by Tenant, its employees, agents or parties Tenant
has contracted with to work on the Premises) or (ii) if said defects and/or
damaged item(s) are not material, Landlord may elect, in its sole and absolute
discretion, not to repair such item(s), but to acknowledge in written form the
defect and/or damaged item(s):in which case, notwithstanding anything to the
contrary in said Lease Paragraph 5 ("Acceptance and Surrender"), Tenant shall
not be responsible upon Lease Termination to repair said item(s) so noted by
Landlord. Landlord shall have thirty (30) days thereafter (or longer if
necessary, provided Landlord is diligently pursuing the completion of the same)
to complete, at Landlord's expense, the "punch list" items without the
Commencement Date of the Lease and Tenant's obligation to pay Rental thereunder
being affected. Notwithstanding the foregoing, a crack in the foundation, or
exterior walls or any other defect in the structure or Building that does not
endanger the structural integrity of the building, or which is not life-
threatening, shall not be considered material, nor shall Landlord be responsible
for repair of same. This Paragraph shall be of no force and effect if Tenant
shall fail to give any such notice to Landlord within thirty (30) days after the
Commencement Date of this Lease.

53.  MAINTENANCE OF THE PREMISES: Notwithstanding anything to the contrary in
     ---------------------------
Paragraph 7, Landlord shall repair, damage to the structural shell, foundation,
and roof structure (but not the interior improvements, roof membrane, or
glazing) of the building leased hereunder at Landlord's cost and expense
provided Tenant has not caused such damage, in which event Tenant shall be
responsible for 100 percent of any such costs for repair or damage so caused by
the Tenant. Notwithstanding the foregoing, a crack in the foundation or exterior
walls, or any other defect in the Building that does not

                                       15
<PAGE>

endanger the structural integrity of the building for which Tenant is not
responsible, or which is not life-threatening, shall not be considered material,
and Landlord may elect, in its sole and absolute discretion, not to repair
and/or replace the same.

54.  COMPLIANCE CONTINUED: Any non-conformance of the improvements installed and
     --------------------
paid for by Landlord as set forth on Exhibit B, required to be corrected by the
                                     ---------
governing agency, shall be corrected at the cost and expense of Landlord if such
non-conformance exists as of the Commencement Date of the Lease and further
provided that such governing agency's requirement to correct the non-conformance
is not initiated as a result of: (i) any future improvements made by or for
Tenant; or (ii) any permit request made to a governing agency by or for Tenant.
Any nonconformance of the Premises occurring after the Commencement Date of this
Lease Agreement shall be the responsibility of Tenant to correct at Tenant's
cost and expense.

55.  ADDITIONAL RENT CONTINUED: The following costs and expenses shall be
     -------------------------
excluded from Additional Rent provided they are not related to the Premises
leased by Tenant:

  A.  Leasing commissions, attorney's fees, costs, disbursements, and other
expenses incurred in connection with negotiations with other third party tenants
(provided said third party tenant is not a subtenant and/or assignee of Tenant),
or disputes between Landlord and other third party tenants, or in connection
with marketing, leasing, renovating, or improving space for other current or
prospective third party tenants or other current or prospective third party
occupants of the Complex; notwithstanding anything to the contrary in Paragraph
4D, any costs mid expenses Landlord is entitled to be reimbursed for as stated
under Paragraph 19 (Bankruptcy and Default") are not included in the "excluded
Additional Rent items" reflected in this Paragraph 55.

     B.  The cost of any service sold to any other third party tenant or other
third party occupant (provided said third party tenant or third party occupant
is not a subtenant and/or assignee of Tenant) for which Landlord is entitled to
be reimbursed as an additional charge or rental over and above the basic rent
and additional rent payable under the lease agreement with said other third
party tenant (including, without limitation, after-hours HVAC costs or over-
standard electrical consumption costs incurred by such other third party
tenants).
