                  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,

                                      -3-

                  Landlord shall have all the rights and remedies with respect
                  thereto as Landlord has for nonpayment of rent.

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

demand, any amount of actual expenses expended by Landlord in excess of said
estimated amount, or Landlord refunding 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.

         Tenant's payment for such Additional Rent as of the commencement of the
term of this lease shall be Twenty Seven Thousand Nine Hundred and 00/100 
($27,900.00) Dollars per month. Any payments required to be made by Tenant for
Additional Rent shall be made by check or instrument separate from that check or
instrument used by Tenant to make any payments for Basic Rent, pursuant to
paragraph 4 A. This paragraph is continued below.

         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.

         E. 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 3201 Ash Street, Palo Alto, CA 94306

time designate in writing.

Lease, Tenant shall deposit with Landlord the sum of One Hundred Seventy Five
Thousand and 00/100 ($175,000.00) Dollars. 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 which Landlord may spend by reason of Tenant's
default or to compensate Landlord for 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

                                      -4-

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. This paragraph is continued below.

others, in any portion of the common area not designated by Landlord for such
use by Tenant. Tenant shall not park nor permit to be parked, any inoperative
vehicles or equipment on any portion of the common parking area or other common

in the Premises in order to measure the amount of electric current, gas or water
consumed for any such excess use. The cost of any such meter and of the
installation, maintenance and repair thereof, all charges for such excess water,
gas and electric current consumed (as shown by such meters and at the rates then
charged by the furnishing public utility); and any additional expense incurred
by Landlord in keeping account of electric current, gas, or water so consumed
shall be paid by Tenant, and Tenant agrees to pay Landlord therefor promptly
upon demand by Landlord. The gas and electric meters directly servicing the
Building at 1855 South Grant Street shall be placed in Tenant's own name and
account, and Tenant shall pay directly to the providing public utilities the
cost of the gas and electric associated solely with the Building at 1855 South
Grant Street. This paragraph continues below.

12. TAXES

         A. As Additional Rent and in accordance with Paragraph 4 D of this
Lease, Tenant shall pay to Landlord Tenant's proportionate share of all Real
Property Taxes, which prorata share shall be allocated to the leased Premises by
square footage or other equitable basis, as calculated by Landlord. 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 Complex) 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 Complex (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 Complex
(regardless of ownership); the fixtures, equipment and other property of
Landlord, real or personal, that are an integral part of and located in the
Complex; or parking areas, public utilities, or energy within the Complex; (ii)
all charges, levies or fees imposed by reason of environmental regulation or
other governmental control of the Complex; and (iii) all costs and fees
(including attorneys' fees) incurred by Landlord in 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
Complex prevailing as of the 

                                      -9-

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 value, use or occupancy of the Complex or
Landlord's interest therein or (ii) on or measured by the gross receipts, income
or rentals from the Complex, on Landlord's business of leasing the Complex, or
computed in any manner with respect to the operation of the Complex, 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 Complex, then only that
part of such Real Property Tax that is fairly allocable to the Complex 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

              (1) 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
if 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 any such taxes so paid
under protest, and any amount so recovered shall belong to Tenant.

              (2) If the Tenant improvements in the Premises, whether installed,
and/or paid for by Landlord or Tenant and whether or not affixed to the real
property so as to become a part thereof, are assessed for Real Property Tax
purposes at a valuation higher than the valuation at which standard office
improvements in other space in the Complex are assessed, then the Real Property
Taxes and assessments levied against Landlord or the Complex by reason of such
excess assessed valuation shall be deemed to be taxes levied against personal
property of Tenant and shall be governed by the provisions of 12A(i), above. If
the records of the County Assessor are available and sufficiently detailed to
serve as a basis for determining whether said Tenant improvements are assessed
at a higher valuation than standard office improvements in other space in the
Complex, such records shall be binding on both the Landlord and the Tenant. If
the records of the County Assessor are not available or sufficiently detailed to
serve as a basis for making said determination, the actual cost of construction
shall be used.

13. LIABILITY INSURANCE   Tenant, at Tenant's expense, agrees to keep in force
during the term of this Lease a policy of comprehensive public liability
insurance with limits in the amount of $1,000,000/$1,000,000 for injuries to or
death of persons occurring in, on or about the Premises or the Complex, and
property damage insurance with limits of $500,000. The policy or policies
affecting such insurance, certificates of which shall be furnished to Landlord,
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

                                      -10-

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.
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 13 is not adequate, Tenant agrees to increase said coverage to such
reasonable amount as Landlord's Lender, insurance advisor or counsel shall deem
adequate.

14. TENANT'S PERSONAL PROPERTY INSURANCE AND WORKER'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 ensuring 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 worker's
compensation insurance and any other employee benefit insurance sufficient to
comply with all laws.

15. 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 Tenant's proportionate share (calculated on a square footage or
other equitable basis as calculated by Landlord) of the cost of policy or
policies of insurance covering loss or damage to the Premises and Complex 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 or the Complex, 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
Complex.

         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.

16. 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 or the Complex 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 or the Complex but excluding, however, the 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 the principal cause of which is the
negligence of Landlord, 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.

                                      -11-

17. COMPLIANCE   Except as may be limited per paragraph 43 (as amended)
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; 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 judgment of any court of competent jurisdiction or 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. This paragraph shall not be interpreted as
requiring Tenant to make structural changes or improvements, except to the
extent such changes or improvements are required as a result of Tenant's use of
the Premises. 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 the Premises. This paragraph is continued below.

18. LIENS   Tenant shall keep the Premises and the Complex 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.

19. 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 or delayed. Tenant
agrees to pay to Landlord, as additional rent, 50% of all rents or additional
consideration excluding any consideration for use of Tenant's personal property
such as furniture, telephones, etc. received by Tenant from its assignees,
transferees or subtenants in excess of the rent payable by Tenant to Landlord
hereunder. Tenant shall, by one hundred twenty (120) 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. In the event Tenant is allowed to assign, transfer or sublet the whole
or any part of the Premises, with the prior written 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 may
require Tenant to pay all expenses in connection with the assignment and
Landlord may require Tenant's assignee or transferee (or other assignees or

                                      -12-

transferees) to assume in writing all of the obligations under this Lease and
for Tenant to remain liable to Landlord under the Lease. This paragraph is
continued below.

20. 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. Tenant hereby irrevocably appoints Landlord the attorney in fact of
Tenant to execute, deliver and record any such instrument or instruments for
and in the name and on behalf of 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. Tenant agrees to send to any mortgagees
and/or deed of trust holders, by registered mail, a copy of any notice of
default served by Tenant upon the Landlord, provided that prior to such notice,
Tenant has been notified, in writing (by way of notice of assignment of rents or
otherwise) of the addresses of such mortgagees and/or deed of trust holders.
Tenant further agrees that if Landlord shall have failed to cure such default
within the time provided for in this Lease, any such mortgagees and/or deed of
trust holders shall have an additional thirty (30) days within which to cure
such default, or if such default is not reasonably susceptible of cure within
that time, then such additional time as may be reasonably necessary if within
such (30) days, any mortgagee and/or deed of trust holder has commenced and is
diligently pursuing the remedies necessary to cure such default, (including but
not limited to commencement of foreclosure proceedings), in which event this
Lease shall not be terminated when such remedies are being diligently pursued.
This paragraph is continued below.

21. ENTRY BY LANDLORD   Except in the case of an emergency, upon 2 hours
advanced notice Landlord reserves, and shall at all reasonable times have, the
right to enter the Premises to inspect them; to perform any services to be
provided by Landlord hereunder; to submit the Premises to prospective
purchasers, mortgagers or tenants; to post notices of nonresponsibility; and to
alter, improve or repair the Premises and any portion of the Complex, 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. For
each of the foregoing purposes, Landlord shall at all times have and retain a
key with which to unlock all of the doors in an emergency in order to obtain
entry to the Premises, and any entry to the Premises obtained by Landlord by any
of said means, or otherwise, 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. Landlord shall also have the right at any time to change the
arrangement or location of entrances or passageways, doors and doorways, and
corridors, elevators, stairs, toilets or other public parts of the Complex and
to change the name, number or designation by which the Complex is commonly
known. and none of the foregoing shall be deemed an actual or constructive
eviction of Tenant, or shall entitle Tenant to any reduction of rent hereunder.

22. 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

                                      -13-

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 the
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 ten (10) days from the date of written
notice from Landlord within which to cure or commence to cure any other default
under this Lease and shall not be in default as long as Tenant diligently
proceeds to cure the non-monetary default. 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 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 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.

                                      -14-

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

         (d) The right and power, as attorney-in-fact for Tenant, 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, as attorney-in-fact for Tenant, 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 sole discretion may deem advisable, with the right to
make alteration 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 cost of such subletting, including, but not limited
to, reasonable attorneys' fees, and any real estate commissions actually paid,
and the cost of such 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 to 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. For all purposes set forth
in this subparagraph (d), Landlord is hereby irrevocably appointed
attorney-in-fact for Tenant, with power of substitution. No taking possession of
the Premises by Landlord, as attorney-in-fact for Tenant, 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 as attorney-in-fact for Tenant pursuant to subparagraph (d)
above.

23. 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.

24. DESTRUCTION   In the event the Premises are destroyed in whole or in part
from any cause, 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.

         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

                                      -15-

Landlord agrees, at its expense, 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 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 embargoes, 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, and 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. In the event the destruction of the Premises is caused by
Tenant, Tenant shall pay the deductible portion of Landlord's insurance
proceeds.

25. 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 in 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 (i) 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, or (ii) any of the foregoing events occur
with respect to the taking of any space in the Complex not leased hereby, or if
any such spaces so taken or conveyed in lieu of such taking and Landlord shall
decide to discontinue the use and operation of the Complex, or decide to
demolish, alter or rebuild the Complex, then, in any of such events 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

                                      -16-

business. 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.

26. SALE OR CONVEYANCE BY LANDLORD   In the event of a sale or conveyance of the
Complex or any interest therein, by any owner of the reversion then constituting
Landlord, 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 Complex 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.

27. 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, 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.

28. 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 two hundred (150%) percent of the monthly Basic Rent required
during the last month of the Lease term.

29. 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

                                      -17-

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.

30. 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, or
any changes in plans for any other portion of the Complex 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.

31. RIGHT OF LANDLORD TO PERFORM   All terms, covenants and conditions of this
Lease to be performed or observed by Tenant shall be 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 or shall fail to perform any other term or covenant hereunder on
its part to be performed, and such failure shall continue for five (5) days
after written notice thereof by Landlord, Landlord, without waiving or releasing
Tenant from any obligation of Tenant hereunder, may, but shall not be obligated
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 of 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.

32. ATTORNEYS' FEES

         (A) In the event that Landlord 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
Tenant hereunder, then all costs and expenses, including reasonable attorneys'
fees, incurred by the prevailing party therein shall be paid by the other party,
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 judgement.

         (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.

33. 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.

                                      -18-

34. 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 or if sent by United States certified
or registered mail, postage prepaid, addressed to Tenant at the Premises:
Attention: Chief Financial Officer with a copy to V.P. Legal Affairs. 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 3201 Ash Street, Palo Alto, CA 94306.
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.

35. 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. Landlord and Tenant mutually intend
that neither shall have any binding contractual obligations to the other with
respect to the matters referred to herein unless and until this instrument has
been fully executed by both parties.

36. 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 thirty (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.

37. 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.

38. BASIC RENT ADJUSTMENT   It is understood that on each and every anniversary
of the date Tenant takes possession, the Basic Rent provided for in Paragraph 4
A of the Lease shall be adjusted in accordance with the following formula based
on the Consumer Price Index ("CPI") for all urban Consumers, subgroup "All
Items," San Francisco-Oakland, California Metropolitan Area (1967 = 100)
published by the Bureau of Labor Statistics, U.S. Department of Labor (the
"Index") published nearest the date Tenant taken possession of the Premises (the
"Beginning Index") and the Index which is published nearest but prior to each
and every anniversary of the date on which Tenant takes possession of the
Premises (the "Adjustment Index"). The "CPI" adjusted Basic Rent shall be
calculated by multiplying the Basic Rent provided for in Paragraph 4 A of the
Lease by a fraction, the numerator of which is the Adjustment Index and the
denominator of which is the Beginning Index. In no event, however, shall the
"CPI" adjusted Basic Rent

                                      -19-

decrease below the Basic Rent provided for in Paragraph 4A of the Lease or any
subsequent adjustment thereof. If the Index is changed so that the Base Year of
the Index differs from that used as of the month immediately preceding the month
in which the term commences, the Index shall be convened in accordance with the
conversion factor published by the United States Department of Labor, Bureau of
Labor Statistics. If the Index is discontinued or revised during the term, such
other government index or other computation with which it is replaced shall be
used in order to obtain substantially the same result as would be obtained if
the Index had not been discontinued or revised. In no event shall the annual
adjustment exceed 6% for any given year to year adjustment. If the CPI exceeds
6% for any given annual period, the increase for the subsequent 12 month period
shall be 6%.

39. LIMITATION OF LIABILITY   In consideration of the benefits accruing
hereunder, Tenant and all successors and assigns covenant and agree that, in the
event of any actual or alleged failure, breach or default hereunder by Landlord:

(i)     the sole and exclusive remedy shall be against Landlord and Landlord's
        assets;

(ii)    no partner of Landlord shall be sued or named as a party in any suit or
        action (except as may be necessary to secure jurisdiction of the
        partnership);

(iii)   no service of process shall be made against any partner of Landlord
        (except as may be necessary to secure jurisdiction of the partnership);

(iv)    no partner of Landlord shall be required to answer or otherwise plead to
        any service of process;

(v)     no judgment shall be taken against any partner of Landlord;

(vi)    any judgment taken against any partner of Landlord may be vacated and
        set aside at any time without hearing;

(vii)   no writ of execution will ever be levied against the assets of any
        partner of Landlord;

(viii)  these covenants and agreements are enforceable both by Landlord and also
        by any partner of Landlord.

(ix)    The term "Landlord," as used in this section, shall mean only the owner
        or owners from time to time of the fee title or the tenant's interest
        under a ground lease of the land described in Exhibit "B," and in the
        event of any transfer of such title or interest, Landlord herein named
        (and in case of any subsequent transfers the then grantor) shall be
        relieved from and after the date of such transfer of all liability as
        respects Landlord's obligations thereafter to be performed, provided
        that any funds in the hands of Landlord or the then grantor at the time
        of such transfer in which Tenant has an interest shall be delivered to
        the grantee. Similarly, the obligations contained in this Lease to be
        performed by Landlord shall be binding on Landlord's successors and
        assigns only during their respective periods of ownership. Tenant agrees
        that each of the foregoing covenants and agreements shall be applicable
        to any covenant or agreement either expressly contained in this Lease or
        imposed by statute or at common law.

40. BROKERS   Tenant warrants that it had dealing with only the following real
estate brokers or agents in connection with the negotiation of this Lease:
CB Commercial Real Estate Group and Cornish & Carey and that it knows of no 
other real estate broker or agent who is entitled to a commission in 
connection with this Lease.

41. SIGNS   No sign, placard, picture, advertisement, name or notice shall be
inscribed, displayed, printed or affixed on or to any part of the outside of the
Premises or any exterior windows of the Premises without the written consent of
Landlord first had and obtained and Landlord shall have the right to remove any
such sign, placard, picture, advertisement, name or notice without notice to and
at the expense of Tenant. If Tenant is allowed to print or affix or in

                                      -20-

any way place a sign in, on, or about the Premises, then upon expiration or
other sooner termination of this Lease, Tenant at Tenant's sole cost and expense
shall both remove such sign and repair all damage in such a manner as to restore
all aspects of the appearance of the Premises to the condition prior to the
placement of said sign.

         All approved signs or lettering on outside doors shall be printed,
painted, affixed or inscribed at the expense of Tenant by a person approved of
by Landlord.

         Tenant shall not place anything or allow anything to be placed near the
glass of any window, door partition or wall which may appear unsightly from
outside the Premises. This Paragraph 41 continues below.

42. FINANCIAL STATEMENTS   In the event Tenant tenders to Landlord any
information on the financial stability, creditworthiness or ability of the
Tenant to pay the rent due and owing under the Lease, then Landlord shall be
entitled to rely upon the information provided in determining whether or not to
enter into this Lease Agreement with Tenant and Tenant hereby represents and
warrants to Landlord the following: (i) That all documents provided by Tenant to
Landlord are true and correct copies of the original; and (ii) Tenant has not
withheld any information from Landlord which is material to Tenant's
creditworthiness, financial condition or ability to pay the rent; and (iii) all
information supplied by Tenant to Landlord is true, correct and accurate; and

to Landlord under the terms of this Lease or available to Landlord under the
laws of the State of California.

43. HAZARDOUS MATERIALS

         A. As used herein, the term "Hazardous Material" shall mean any
substance or material which has been determined by any state, federal or local
governmental authority to be capable of posing a risk of injury to health,
safety or property including all of those materials and substances designated or
defined as "hazardous" or toxic by (i) the Environmental Protection Agency, the
California Water Quality Control Board, the Department of Labor, the California
Department of Industrial Relations, the Department of Transportation, the
Department of Agriculture, the Consumer Product Safety Commission, the
Department of Health and Human Services, the Food and Drug Agency or any other
governmental agency now or hereafter authorized to regulate materials and
substances in the environment, or by (ii) the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, 42 U.S.C. 9601 et seq., as
amended; the Hazardous Materials Transportation Act, 49 U.S.C. 1801, et seq., as
amended; the Resource Conservation and Recovery Act, 42 U.S.C. 6901, et seq., as
amended; the Hazardous Waste Control Law, California Health & Safety Code 25100
et seq., as amended; Sections 66680 through 66685 of Title 22 of the California
Administration Code, Division 4, Chapter 30, as amended; and in the regulations
adopted and publications promulgated pursuant to said laws.

         B. Tenant shall not cause or permit any Hazardous Material to be
improperly or illegally used, stored, discharged, released or disposed of in,
from, under or about the Premises or the Complex, or any other land or
improvements in the vicinity of the Premises or the Complex. Without limiting
the generality of the foregoing, Tenant, at its sole cost, shall comply with all
laws relating to Hazardous Materials. If the presence of Hazardous Materials on
the Premises or the Complex caused or permitted by Tenant results in
contamination of the Premises or the Complex or any soil in or about the
Premises or the Complex, Tenant, at its expense shall promptly take all actions
necessary to return the Premises or the Complex to the condition existing prior
to the appearance of such Hazardous Material. The termination of this Lease
shall not terminate or

                                      -21-

reduce the liability or obligations of Tenant under this Section, or as may be
required by law, to clean up, monitor or remove any Hazardous Materials from the
Premises or the Complex.

         Tenant shall defend, hold harmless and indemnify Landlord and its
agents and employees with respect to all claims, damages and liabilities arising
out of or in connection with any Hazardous Material used, stored, discharged,
released or disposed of in, from, under or about the Premises or the Complex,
where said Hazardous Material is or was attributable to the activities of
Tenant, its agents or contractors during the Lease term and whether or not
Tenant had knowledge of such Hazardous Material, including, without limitation,
any cost of monitoring or removal, any reduction in the fair market value or
fair rental value of the Premises or the Complex and any loss, claim or demand
by any third person or entity relating to bodily injury or damage to real or
personal property.

              Tenant shall not suffer any lien to be recorded against the
Premises or the Complex as a consequence of a Hazardous Material, including any
so called state, federal or local "super fund" lien related to the "clean up" of
a Hazardous Material in or about the Premises, where said Hazardous Material is
or was attributable to the activities of Tenant.

         C. In the event Hazardous Materials are discovered in or about the
Premises or the Complex, and Landlord has substantial reason to believe that
Tenant was responsible for the presence of the Hazardous Material, then Landlord
shall have the right to appoint a consultant, at Tenant's expense, to conduct an
investigation to determine whether Hazardous Materials are located in or about
the Premises or the Complex and to determine the corrective measures, if any,
required to remove such Hazardous Materials. Tenant, at its expense, shall
comply with all recommendations of the consultant, as required by law. To the
extent it is determined that Tenant was not responsible for the presence of the
Hazardous Materials, then Landlord shall reimburse Tenant for any costs incurred
by Landlord and paid by Tenant under the terms of this paragraph 45.C.

         Tenant shall immediately notify Landlord of any inquiry, test,
investigation or enforcement proceeding by or against Tenant or the Premises or
the Complex concerning a Hazardous Material. Tenant acknowledges that Landlord,
as the owner of the Property, at its election, shall have the sole right, at
Tenant's expense, to negotiate, defend, approve and appeal any action taken or
order issued with regard to a Hazardous Material by an applicable governmental
authority. Provided Tenant is not in default under the terms of this Lease,
Tenant shall likewise have the right to participate in any negotiations,
approvals or appeals of any actions taken or orders issued with regard to the
Hazardous Material and Landlord shall not have the right to bind Tenant in said
actions or orders.

         D. It shall not be unreasonable for Landlord to withhold its consent to
any proposed assignment or subletting if (i) the proposed assignee's or
subtenant's anticipated use of the Premises involves the storage, use or
disposal of Hazardous Material; (ii) if the proposed assignee or subtenant has
been required by any prior landlord, lender or governmental authority to "clean
up" Hazardous Material; (iii) if the proposed assignee or subtenant is subject
to investigation or enforcement order or proceeding by any governmental
authority in connection with the use, disposal or storage of a Hazardous
Material.

         E. Tenant shall surrender the Premises to Landlord, upon the expiration
or earlier termination of the Lease, free of Hazardous Materials which are or
were attributable to Tenant. If Tenant fails to so surrender the Premises,
Tenant shall indemnify and hold Landlord harmless from all damages resulting
from Tenant's failure to surrender the Premises as required by this paragraph,
including, without limitation, any claims or damages in connection with the
condition of the Premises including, without limitation, damages occasioned by
the inability to relet the

                                      -22-

Premises or a reduction in the fair market and/or rental value of the Premises
or the Complex by reason of the existence of any Hazardous Materials, which are
or were attributable to the activities of Tenant, in or around the Premises or
the Complex.

         Notwithstanding any provision to the contrary in this Lease, if any
action is required to be taken by a governmental authority to clean-up, monitor
or remove any Hazardous Materials, which are or were attributable to the
activities of Tenant, from the Premises or the Complex and such action is not
completed prior to the expiration or earlier termination of the Lease, then at
Landlord's election (i) this Lease shall be deemed renewed for a term commencing
on the expiration date of this Lease and ending on the date the clean-up,
monitoring or removal procedure is completed (provided, however, that the total
term of this Lease shall not be longer than 34 years and 11 months); or (ii)
Tenant shall be deemed to have impermissibly held over and Landlord shall be
entitled to all damages directly or indirectly incurred in connection with such
holding over, including without limitation damages occasioned by the inability
to relet the Premises or a reduction in the fair market and/or fair rental value
of the Premises or the Complex by reason of the existence of the Hazardous
Material.

         F. Upon the Lease Commencement Date, Tenant shall provide to Landlord a
complete list of all chemicals, toxic waste or Hazardous Materials employed by
Tenant within the Premises. Throughout the term of the Lease, Tenant shall
continue to update this list of chemicals, contaminants and Hazardous Materials.
This paragraph is continued below.

Paragraph 4.A. BASIC RENT (continued)

         As of the execution date of this Lease, Landlord and Tenant hereby
acknowledge that it is Tenant's intention to sublease the second and third
floors of the Premises. The agreed upon rentable square footage for the second
and third floors (which square footage indicated for each floor includes that
particular floor's proportionate share of Building common areas such as the
first floor Lobby, elevators, restrooms, stairwells and exit corridors) is
hereby agreed to be 13,961 rentable square feet per floor. The monthly Basic
Rent for each of the second and third floors as of the commencement of the Lease
is hereby agreed to be $27,223.95 per month (13,961 s.f. x $1.95).
Notwithstanding anything herein to the contrary, Landlord agrees to postpone the
commencement of Basic Rent on the second floor to September 1st, 1996 and on the
third floor to October 15th, 1996 for the purpose of phasing in Tenant's
subtenants. In the event that a subtenant occupies and commences payment of
Basic Rent prior to September 1st, 1996 for the second floor and October 15,
1996 for the third floor, then Tenant's Basic Rent obligations shall commence
upon the same day as the commencement of the subtenants obligations. Any credits
due Tenant under this "phase-in" arrangement shall be credited against the
November Basic Rent payment.

Paragraph 4D.  ADDITIONAL RENT (continued)

         Tenant hereby acknowledges that the Additional Rent estimated per
paragraph 4D of the Lease has been prepared by Landlord. The actual cost
incurred is directly related to the manner in which Tenant uses and occupies the
Premises. Landlord's estimate is based on the following per square foot per
month estimate of expenses:

The above estimate is for calendar year 1996, and shall be adjusted per paragraph 4D of the Lease. The following squire footages are stated for reference: 1825 South Grant Street (Building I) 155,489 s.f. 1875 South Grant Street (Building II) 170,922 s.f. 1855 South Grant Street (Building III) 66,426 s.f. ------------ Total square footage 392,837 s.f.
Tenant's percentage occupancy is therefore as follows: Percent of Building = 100% Percent of Complex 66,426 divided by 392,387 = 16.9% The following shall be exclusions to any operating expenses as defined under this Lease. a) Costs incurred to provide services to other tenants which are not furnished to Tenant. b) Expenses for which the Landlord is reimbursed or indemnified either by an insured, condemnor, tenant or otherwise. c) Any Ground Lease rental expenses. d) The cost of correcting defects in the construction of the Building or defects in the Building equipment (excluding normal maintenance.) Within 90 days after receipt of Landlord's Statement (the "Statement") setting forth Tenant' share of actual expenses of operation, management and maintenance of the Complex, Premises and Building and any other items of Additional Rent (the "Operating Expenses and Real Property Taxes"), Tenant shall have the right to audit at Landlord's local offices, at Tenant's expense, Landlord's accounts and records relating thereto. Such audit shall be conducted by a certified public accountant approved by Landlord, which approval shall not be unreasonably withheld. If such audit reveals that Landlord has overcharged Tenant, the amount overcharged shall be paid to Tenant within 30 days after the audit is concluded, together with interest thereon at the rate of 10% per annum, from the date the Statement was delivered to Tenant until payment of the overcharge is made to Tenant. In addition, if the Statement exceeds the actual Operating Expenses and Real Property Taxes which should have been charged to Tenant by more than 5%, the cost of the audit shall be paid by Landlord. Paragraph 4F. SECURITY DEPOSIT (continued) In addition to the cash security deposit as defined in paragraph 4.F., Tenant agrees to tender to Landlord, within 20 days of execution of this Lease and irrevocable standby Letter of Credit in the amount of $1,325,000. The form of the irrevocable standby Letter of Credit must be acceptable to Landlord. The Letter of Credit must provide that Landlord have the ability to cash or draw the entire amount solely upon Landlord's representing to the issuing Bank that Tenant is in uncured monetary default of the Lease. The Letter of Credit required hereunder shall remain in full force and effect until August 1, 2001. At such time after August 1st, 2001 as the value of Tenant's shareholder equity becomes $70,000,000, then Landlord hereby agrees to cancel the requirement for the additional security provided by this Letter of Credit and to return the Letter of Credit to Tenant. The expiration date of the Letter of Credit shall be the expiration date of this Lease. In the event Tenant has not provided Landlord the Letter of Credit as required, Landlord may prohibit Tenant from occupying the Premises until such time as the Letter of Credit is received by Landlord, and Tenant agrees that Tenant's Basic and Additional Rent obligations shall nevertheless commence without offset or delay even if Tenant is prohibited from occupying the Premises because of Tenant's failure to deliver the Letter of Credit. Paragraph 9. ALTERATIONS AND ADDITIONS (continued) Any alteration or addition to the Premises made by Landlord (or Landlord's contractors) shall be on a "open book" basis. Landlord shall obtain a minimum of three bids on any major cost items involved in any tenant improvements. Tenant may request Landlord bid subcontractors of Tenant's choosing, and subcontractors must be licensed to do business in the State of California. Landlord (or Landlord's contractors) shall receive a 10% fee, which 10% is based on the actual direct cost of construction. The 10% fee shall include general conditions, overhead, and profit. Paragraph 11. UTILITIES (continued) As stated above the gas and electric meters shall be placed in Tenant's own name and account and the cost of these utilities shall be paid directly by Tenant. Tenant shall have access to the Premises (and notwithstanding paragraph 11 access to all utilities) 24 hours a day, seven days a week. Landlord's standard operating times are 8am to 6pm, five days a week for a total of 50 hours per week x 52 weeks = 2600 hours per year. In the event Tenant uses the main HVAC Systems more than 2600 hours per year, for each hour in excessive 2600 hours Tenant agrees to pay the amount of $3.33 per hour as the cost of accelerated wear and tear on the main HVAC System. This amount is calculated as follows: Replacement cost of main System and components $ 125,000 Average Life expectancy of main System and components divided by 37,500 hours Dollars per hour (A divided by B) $ 3.33 per hour
Paragraph 17. COMPLIANCE (continued) Landlord and Tenant each hereby agree that the City of San Mateo issuance of an occupancy permit for the Premises represents that as of the date of the occupancy permit the Premises and Common Areas of the Complex are in full compliance with all applicable building codes, ADA laws, and all other regulations and statutes affecting the Building. If a violation in compliance with the above referenced building codes, etc., is discovered within 180 days of the commencement of this Lease and such violation was caused by Landlord or Landlord's contractors, or agents, Landlord shall correct such violation at Landlord's sole cost and expense. Paragraph 19. ASSIGNMENT/SUBLETTING (continued) Notwithstanding anything to the contrary herein, Landlord's consent shall be deemed given for Tenant to assign or sublet to an affiliate, subsidiary, parent company or successor to the corporate business of Tenant (a "Permitted Assignee") and Tenant agrees to remain liable for the full performance of all lease obligations. Paragraph 20. SUBORDINATION AND MORTGAGES (continued) Notwithstanding anything to the contrary herein, the provisions of any mortgages or the underlying groundlease concerning the Premises shall not increase the financial obligations of Tenant hereunder or adversely affect the leasehold interest of Tenant created hereunder including Tenant's rights and Landlord's obligations. Paragraph 41. SIGNS (continued) Notwithstanding anything herein to the contrary, Landlord agrees to allow Tenant at no additional charge to place one exterior sign on the Building, which sign must be approved by Landlord, and which approval will not be unreasonably withheld. Tenant may also "silkscreen" signage on the exterior lobby entry doors. Tenant shall pay for the cost of said signage. Exhibit "E" is an example of such signage. Exhibit "E" is used for representative purposes only and is not intended to be to scale. Any exterior sign placed on the Building by Tenant must be in complete compliance with the City of San Mateo sign ordinances. Landlord has not received specific approval from the City of San Mateo to place a lighted sign on the Premises. Landlord and Landlord's architect shall use its best efforts to obtain such approval. Two lighted signs have been approved for the Complex and one lighted sign exists on each of the two high rise buildings. In the event the City of San Mateo allows only two lighted signs at the Complex, Landlord agrees to offer to the City of San Mateo to remove the west facing lighted sign on the Building at 1875 South Grant Street and use that approved signage as a trade for Tenant's Premises, or denies Landlord's trade of the lighted sign on 1875 South Grant for a sign on Tenant's Premises, an the result is Tenant does not have signage on the Premises, this shall in no way effect the obligations between Landlord and Tenant hereunder and the Lease shall remain in full force and effect without any diminution of rent or other offset against Landlord. In the event that Tenant occupies more than 200,000 square feet in the Complex, Landlord agrees to substitute Tenant's name for the "Crossroads" west facing sign on the Building at 1875 South Grant Street. The cost of substitution shall be borne by Tenant. Notwithstanding anything herein to the contrary, Landlord hereby approves an internally illuminated sign with the "SIEBEL" logo in PMS-541 blue as shown by the drawing represented by Exhibit E-2. Paragraph 43. HAZARDOUS MATERIALS (continued) Landlord, to the best of Landlord's knowledge without a duty to inspect, has no knowledge of the presence of any hazardous materials in the Building, in the soil upon which the Building is located, or in the groundwater under the Complex. Landlord shall defend, hold harmless and indemnify Tenant with respect to all claims, damages and liabilities arising out of or in connection with any Hazardous Material used, stored, discharged, released or disposed of in, from, under or about the Premises or the Complex, where said Hazardous Material is or was not attributable to the activities of Tenant during the Lease term and whether or not Tenant had knowledge of such Hazardous Material, including, without limitation, any cost of monitoring or removal.

* Subject to existing tenant's option to extend. The ten story Building located at 1875 South Grant Street, as outlined in green on Exhibit F1, has the following full floors coming available on the dates as indicated above. Floor plans of each of the floors becoming available are shown as Exhibits F-2, 3, 4, 5. The existing tenant on the Ninth Floor has a preexisting option to extend its lease. In the even said Tenant exercises its option to extend, the Ninth Floor will not be available and is not subject to this paragraph 45. Landlord hereby grants to Tenant the Option (Subject to the Ninth floor Tenant's option to extend on the 9th floor only) to lease the 10th, 9th, 8th and 4th floors at 1875 South Grant Street. Tenant shall have the Option to lease any or all of the floors subject to this Option. For each floor for which Tenant has this Option, Tenant must exercise its Option to Lease by delivering an Exercise of Option to Landlord in writing on or before the "Date of Exercise of Option" as indicated in the above table. Each floor will become available on the date of availability as indicated. The Lease commencement date for each floor shall be 30 days after the date of availability or upon occupancy of all or a portion of the floor by Tenant's operating personnel, whichever occurs sooner. Tenant shall lease each floor in an as-is condition, with Landlord granting Tenant an improvement allowance of $77,000 per floor towards standard office improvements requested by Tenant. This $77,000 shall be adjusted by the CPI (said CPI as defined in paragraph 38) for the adjustment period beginning August 1st, 1996 to the date of availability for each particular floor represented by this option. The improvement allowance granted Tenant hereunder shall be in form of Basic Rent abatement. For example, if a particular floor leased by Tenant used $77,000 of Landlord's improvement allowance, then for the month immediately succeeding the commencement of Lease for that particular floor, the Basic Rent due and payable due under this Lease shall be reduced by the amount of allowance used. The Termination Date of Lease for each of the floors leased under this paragraph shall be co-terminus with the Lease for the Building at 1855 South Grant Street. Each Floor leased under this paragraph 45 shall also be subject to Tenant's Option to Extend as described below. The Basic Rent for each floor leased under this paragraph 45 shall be at the same Basic Rent per square foot per month as is described in paragraph 4A of the Lease. For example, if Tenant leased the Fourth Floor with a commencement date of 12/15/97, and at that time Tenant's Basic Rent was $2.00 per square foot per month, Tenant's monthly Basic Rent would be 17,702 x $2.00 = $35,404. The Basic Rent per square foot per month will be increased at the same rate per square foot and upon the same dates and in the same manner as is provided for in paragraphs 4.A. and 38 of the Lease. Tenant's Additional Rent shall be at the same rate per square foot per month as is then applicable at the time of occupancy of the floors leased hereunder. For each floor so leased by Tenant, Tenant's parking shall be increased by 52 spaces. Any modifications to the Floors leased by Tenant under this Option shall be made in accordance with Paragraphs 8 to 9 of this Lease, with Tenant paying (subject to Landlord's $77,000 per Floor allowance as indicated above) all costs and expenses associated with any remodel. Upon the date of availability', Tenant shall be granted access to each floor leased by Tenant for the installation of telephone and other communications. Tenant's installation shall not interfere with any of Tenant's requested Improvements to be made by Landlord, and the installation by Tenant of telephone, communication, furniture, and fixtures shall not constitute actual occupancy, but only occupancy with Tenant's operating personnel prior to the 30 day period indicated above shall commence the payment of Basic and Additional Rent. Paragraph 46. SECURITY SYSTEMS Tenant shall have the right to establish its own procedures so as to maintain and protect the internal security of the Premises in accordance with Tenant's needs. Tenant shall have the right to install additional security devices for the Premises, including, without limitation, Security Card Systems for control of access to the Premises. Landlord shall have the reasonable right to review and approve these systems. Tenant acknowledges that Landlord's approval shall be subject to Tenant's agreement to repair any damage to any portion of the Premises resulting from Tenant's installation of any security system, and Tenant agrees to completely restore the Premises to the condition prior to the installation of any security system. Tenant acknowledges that this restoration potentially require replacement of doors, window mullions, door frames and the like. All restoration shall be in accordance with the terms of the Lease.

In the event that VISA's lease expires and the space becomes available Landlord shall notify Tenant in writing of the availability of the space and shall tender to Tenant the terms under which Landlord will lease the space to Tenant. The terms shall include the rent, increases in rent, the term, the size of the space, the Tenant improvement allowances, if any, and the like. Tenant shall have 10 business days within which to accept the proposal made by Landlord. b) In the event Tenant does not accept the proposal by Landlord, then Landlord agrees that it will not lease that same space to another tenant on terms that are more favorable than those proposed to Tenant without first offering the more favorable terms to Tenant and allowing Tenant three business days within which to accept the more favorable terms. c) In the event Tenant fails to accept the proposal from Landlord to lease the floors described on Exhibits G1 and G2 which become available for lease, then Landlord shall have no further obligations to Tenant with respect to these two floors. Paragraph 48. OPTIONS TO EXTEND Provided Tenant is not in default under any of the terms, covenants or conditions of this Lease, and subject to the terms and conditions set forth hereafter, Tenant is granted two options to extend this Lease for two successive five year periods.

(d) The then current payment for Additional Rent described in 4D of the Lease shall continue to be adjusted according to paragraphs 4D of this Lease.
