other place as Landlord may designate from time-to-time. Tenant's obligation to
pay rent shall be prorated at the commencement and expiration of the Lease Term.

        3.4. Late Charge and Interest on Rent in Default: Tenant acknowledges
that the late payment by Tenant of any monthly installment of Base Monthly Rent
or any Additional Rent will cause Landlord to incur certain costs and expenses
not contemplated under this Lease, the exact amount of which are


                                       5
<PAGE>   11

extremely difficult or impractical to fix. Such costs and expenses will include,
without limitation, administration and collection costs and processing and
accounting expenses. Therefore, if any such rent is not received by Landlord
from Tenant within ten (l0) days after the same becomes due, Tenant shall
immediately pay to Landlord a late charge equal to five percent (5%) of such
delinquent rent. Landlord and Tenant agree that this late charge represents a
reasonable estimate of such costs and expenses and is fair compensation to
Landlord for its loss suffered by Tenant's failure to make timely payment. In no
event shall this provision for a late a charge be deemed to grant to Tenant a
grace period or extension of time within which to pay any rental installment or
prevent Landlord from exercising any right or remedy available to Landlord upon
Tenant's failure to pay each rental installment due under this Lease in a timely
fashion. If any rental installment should become delinquent for a period in
excess of thirty (30) days then, in addition to such late charge Tenant shall
pay to Landlord interest on any rent that is not paid when due at the Agreed
Interest Rate from the thirtieth (30th) day following the date such amount
became due until paid.

        3.5. Security Deposit: Tenant has deposited with Landlord the amount set
forth in paragraph 1.8 concurrently with its execution of the Lease (the
"Security Deposit") as security for the performance by Tenant of the terms of
this Lease to be performed by Tenant, and not as prepayment of rent. Landlord
may apply such portion or portions of the Security Deposit as are reasonably
necessary for the following purposes: (i) to remedy any default by Tenant in the
payment of rent; (ii) to repair damage to the Leased Premises caused by Tenant;
(iii) to clean the Leased Premises upon termination of the Lease; and (iv) to
remedy any other default of Tenant as permitted by law. In the event the
Security Deposit or any portion thereof is so used, Tenant agrees to pay to
Landlord promptly upon demand an amount in cash sufficient to restore the
Security Deposit to the full original sum. Landlord shall not be deemed a
trustee of the Security Deposit. Landlord may use the Security Deposit in
Landlord's ordinary business and shall not be required to segregate it from its
general accounts. Tenant shall not be entitled to any interest on the Security
Deposit. If Landlord transfers the Leased Premises during the Lease Term,
Landlord may pay the Security Deposit to any subsequent owner in conformity with
the provisions of Section l950.7 of the California Civil Code and/or any
successor statute, in which event the transferring Landlord will be released
from all liability for the return of the Security Deposit.

        3.6. No Accord and Satisfaction: No payment by Tenant or receipt by
Landlord of a lesser amount than the rent herein


                                       6
<PAGE>   12

provided shall be deemed to be other than on account of the earliest rent due
and payable hereunder, nor shall any endorsement or statement on any check or
any letter accompanying any check or payment as rent be deemed an accord and
satisfaction, and Landlord may accept any such check or payment without
prejudice to Landlord's right to recover the balance of such rent or pursue any
other remedy provided in this Lease.

                                    ARTICLE 4

                             USE OF LEASED PREMISES

        4.1. Limitation on Type: Tenant shall use the Leased Premises solely for
the Permitted Use (as described in paragraph 1.9) and for no other use unless
Tenant shall have first obtained Landlord's prior written consent. Tenant shall
not do or permit anything to be done in or about the Leased Premises which might
interfere with the rights of other tenants of Landlord to use the Property or
cause structural injury to the Leased Premises or the Building. Tenant shall not
commit nor permit to be committed any waste in or about the Leased Premises, and

        4.2. Compliance with Laws and Private Restrictions: Tenant shall not use
or permit any person to use the Leased Premises in any manner which violates any
Laws or Private Restrictions. Tenant shall abide by and promptly observe and
comply with all Laws and Private Restrictions and shall indemnify and hold
Landlord harmless from any liability resulting from Tenant's failure to do so.

        4.3. Insurance Requirements: Tenant shall not use or permit any person
to use the Leased Premises in any manner which will cause the initial rate of

cancellation of any insurance policy covering the Building. Tenant shall not
sell, or permit to be kept, used, or sold in or about the Leased Premises any
article which may be prohibited by the standard form of fire insurance policy.
Tenant shall comply with all reasonable requirements of any insurance company,
insurance underwriter, or Board of Fire Underwriters which are necessary to
maintain, at standard rates, the insurance coverage carried by either Landlord
or Tenant pursuant to this Lease.

        4.4. Signs: Tenant shall not place on any portion of the Leased
Premises, the Building or the Property any sign, placard, lettering in or on
windows, banner, displays or other advertising or communicative material which

                                       7
<PAGE>   13

approved signs shall strictly conform to all Laws, Private Restrictions and
Landlord's sign criteria, if any, and shall be installed at the expense of
Tenant. If Landlord so elects, Tenant shall, at the expiration or sooner
termination of this Lease, remove all signs installed by it and repair any
damage caused by such removal. Tenant shall at all times maintain such signs in
good condition and repair. Tenant may utilize the entire monument provided to
the Building for signage.

        4.5. Rules and Regulations: Landlord from time-to-time may elect to
promulgate reasonable and non-discriminatory rules and regulations applicable to
all occupants of the Property for the care and orderly management of the
Property and the safety of its tenants and invitees. Such rules and regulations
shall be binding upon Tenant upon delivery of a copy thereof to Tenant, and
Tenant agrees to abide by such rules and regulations. If there is a conflict
between the rules and regulations and any of the provisions of this Lease, the
provisions of this Lease shall prevail. Landlord shall not be responsible for
the violation by any other tenant of the Property of any such rules and
regulations.

        4.6. Parking: Tenant is allocated a minimum of eighty (80) parking
spaces and shall have the exclusive right to use the parking spaces contained
within the Property described in paragraph 2.1 for its use and the use of its
employees and invitees, the location of which may be designated from
time-to-time by Landlord. All trucks and delivery vehicles shall be (i) parked
at the rear of the Building, (ii) loaded and unloaded in a manner which does not
interfere with the businesses of other occupants of the Property, and (iii)
permitted to remain on the Property only so long as is reasonably necessary to
complete loading and unloading.

                    TRADE FIXTURES AND LEASEHOLD IMPROVEMENTS

        5.1. Trade Fixtures: Throughout the Lease Term, Tenant shall provide,
install, and maintain in good condition all Trade Fixtures required in the
conduct of its business in the Leased Premises. All Trade Fixtures shall remain
Tenant's property.

        5.2. Leasehold Improvements: Tenant shall not construct any Leasehold
Improvements or otherwise alter the Leased Premises without Landlord's prior
approval, if the cost thereof exceeds Ten Thousand Dollars ($l0,000.00), and not
until Landlord shall have first approved the plans and specifications therefor,
which approvals shall not be unreasonably withheld. In no event shall Tenant
make any alterations to the Lease Premises which could affect the structural
integrity or the design of the Building. All Leasehold Improvements constructed
by Tenant shall be constructed by Tenant at Tenant's expense using a licensed
contractor first approved by Landlord in substantial compliance with the
approved plans and specifications therefor. All construction done by Tenant
shall be done in accordance with all Laws and in a good and workmanlike manner
using new materials of good quality. Tenant shall not commence construction of
any Leasehold Improvements until (i) all required governmental approvals and
permits shall have been obtained, (ii) all requirements regarding insurance
imposed by this Lease have been satisfied, (iii) Tenant shall have given
Landlord at least five (5) days prior written notice of its intention to
commence such construction, (iv) Tenant shall have notified Landlord by

if requested by Landlord, Tenant shall have obtained contingent liability and
broad form builders risk insurance in an amount satisfactory to Landlord if
there are any perils relating to the proposed construction not covered by
insurance carried pursuant to Article 9. All Leasehold Improvements shall remain
the property of Tenant during the Lease Term but shall not be damaged, altered,
or removed from the Leased Premises. At the expiration or sooner termination of
the Lease Term, all Leasehold Improvements shall be surrendered to Landlord as a
part of the realty and shall then become Landlord's property, and Landlord shall
have no obligation to reimburse Tenant for all or any portion of the value or
cost thereof; provided, however, that if Landlord shall require Tenant to remove
any Leasehold Improvements in accordance with the provisions of paragraph 15.1,
then Tenant shall so remove such Leasehold Improvements prior to the expiration
of the Lease Term.

<PAGE>   15

        5.3. Alterations Required by Law: Tenant shall make any alteration,
addition or change of any sort, whether structural or otherwise, to the Leased
Premises that is required by any Law because of (i) Tenant's use or change of
use of the Leased Premises, (ii) Tenant's application for any permit or
governmental approval, or (iii) Tenant's construction or installation of any
Leasehold Improvements or Trade Fixtures. Notwithstanding the above to the
contrary, Landlord agrees that in the event Landlord's Work described in
paragraph 2.3. causes the City of Sunnyvale to demand that the Premises be
brought into compliance with handicap accessibility standards as provided in the
Americans With Disabilities Act ("ADA") that Landlord shall be solely
responsible for the cost and performance of the work required. It is further
agreed that if the construction of Tenant's Improvements constructed with the
Tenant Improvement Allowance provided for in paragraph 2.3. and EXHIBIT "C"
triggers a requirement by the City of Sunnyvale that the Premises be brought
into compliance with applicable Federal, State and local codes relating to such
handicap accessibility standards that any such cost and work required shall be
the sole responsibility of Tenant.

        5.4. Landlord's Improvements: All fixtures, improvements or equipment
which are installed, constructed on or attached to the Property by Landlord at
its expense shall become a part of the realty and belong to Landlord.

        5.5. Liens: Tenant shall keep the Leased Premises and the Property free
from any liens and shall pay when due all bills arising out of any work
performed, materials furnished, or obligations incurred by Tenant, its agents,
employees or contractors relating to the Leased Premises. If any claim of lien
is recorded, Tenant shall bond against or discharge the same within ten (10)
days after the same has been recorded against the Leased Premises and/or the
Property.

                             REPAIR AND MAINTENANCE

        6.1. Tenant's Obligations to Maintain: Except as otherwise provided in
Article 11 regarding the restoration of damage caused by fire and other perils,
Tenant shall, at all times during the Lease Term, clean, keep, and maintain in
good order, condition, and repair (reasonable wear and tear excepted) the Leased
Premises and every part thereof, through regular inspections and servicing,
including but not limited to (i) all plumbing and sewage facilities (including
all sinks, toilets, faucets and drains), and all ducts, pipes, vents, or other
parts of the HVAC or plumbing system, (ii) all fixtures, interior walls, floors,


                                       10
<PAGE>   16

carpets and ceilings, (iii) all windows, doors, entrances, plate glass,
showcases, including cleaning both interior and exterior surfaces, (iv) all
electrical facilities and all equipment including all lighting fixtures, lamps,
bulbs and tubes, fans, vents, exhaust equipment and systems, (v) any automatic
fire extinguisher equipment in the Leased Premises, (vi) ceilings, roofs,
skylights, roof gutters and drains, and (vii) landscaping, driveways, parking
lots, retaining walls, signs, sidewalks, and parkways located in, on, about or
adjacent to the Premises. Tenant, in keeping the Premises in good order,
condition and repair, shall exercise and perform good maintenance practices.
Tenant's obligations shall include restorations, replacements or renewals when
necessary to keep the Premises and all improvements thereon or a part thereof in
good order, condition and state of repair. If Tenant occupies the Premises for
seven (7) years or more, Landlord may require Tenant to repaint the exterior of
the buildings on the Premises as reasonably required, but not more frequently
than once every seven (7) years. Tenant shall replace any damaged or broken
glass in the Leased Premises (including all interior and exterior doors,
windows, and showcases) with glass of the same kind, size and quality. Tenant
shall repair any damage to the Leased Premises (including exterior doors and
windows) caused by vandalism or any unauthorized entry. Tenant shall (i)
maintain, repair, and replace when necessary all HVAC equipment, roof covering,
landscaping and parking lot surface areas which serves the Leased Premises and
shall keep the same in good condition through regular inspection and servicing,
and (ii) maintain continuously throughout the Lease Term a service contract for
the maintenance of all such HVAC equipment with a licensed HVAC repair and
maintenance contractor approved by Landlord which provides for the periodic
inspection and servicing of the HVAC equipment at least once every sixty (60)
days during the Lease Term. Landlord may elect at any time to assume
responsibility for the maintenance, repair and replacement of such HVAC
equipment, roof covering, landscaping, and parking lot surface which serves the
Leased Premises, and if it does so, all costs incurred by it in performing such
maintenance, repair and replacement shall be paid for by Tenant on a periodic
basis as Additional Rent within ten (l0) days after receipt of a statement
therefor from Landlord. Tenant shall also maintain continuously throughout the
Lease Term a service contract for the washing of all windows in the Leased
Premises (exterior surfaces) with a contractor approved by Landlord which
provides for the periodic washing of all such windows at least once every six
(6) months during the Lease Term. Tenant shall furnish Landlord with copies of
all such service contracts, which shall provide that they may not be canceled or
changed without at least thirty (30) days prior written notice to Landlord. All
repairs and replacements required of Tenant shall be promptly made with new
materials of like kind and quality. If the work affects the structural parts


                                       11
<PAGE>   17

of the Building or if the estimated cost of any item of repair or replacement is
in excess of Ten Thousand Dollars ($l0,000.00), then Tenant shall first obtain
Landlord's written approval of the scope of work, plans therefor, materials to
be used, and the contractor.

        6.2. Landlord's Obligation to Maintain: Landlord shall maintain and
repair (i) the structural portions of the roof; (ii) the foundation (but not the
floor covering) of the Building; (iii) the exterior walls of the Building
(subject to Section 6.1., above) so that the same is kept in good order and
repair, reasonable wear and tear excepted; and (iv) any damages to the Premises
caused by the negligence or willful misconduct of Landlord or Landlord's
Parties. Landlord shall not be responsible for repairs required by any accident,
fire or other peril except as otherwise required by Article 11, or for damage
caused to any part of the Property by any act, negligence or omission of Tenant
or its agents, contractors, or employees or invitees. Landlord may engage
contractors of its choice to perform the obligations required of it by this
Article, and the necessity of any expenditure to perform such obligations shall
be at the reasonable discretion of Landlord. It is an express condition
precedent to all obligations of Landlord to repair and maintain that Tenant
shall have notified Landlord in writing of the need for such repairs and
maintenance, after which Landlord shall be given a reasonable opportunity to
repair same. Notwithstanding the foregoing, if any repair or replacement is
required to be made to the Leased Premises which would constitute a capital
expenditure under GAAP, then Landlord shall be required to make such repair or
replacement, and Tenant shall be required to pay the costs therefor as
Additional Rent to the extent such costs are amortized over the useful life of
such capital items during the Lease Term.

        6.3. Tenant's Negligence: Anything in this Article to the contrary
notwithstanding, Tenant shall pay for all damage to the Leased Premises or the
Property caused by the negligent act or omission of Tenant, its employees,
contractors, or invitees or by the failure of Tenant to promptly discharge its
obligations under this Lease or comply with the terms of this Lease, but only to
the extent such damage is not covered by insurance proceeds actually recovered
by Landlord. Tenant shall make payment therefore on damages incurred by
Landlord.

                          WASTE DISPOSAL AND UTILITIES

        7.1. Waste Disposal: Tenant shall store its waste either inside the
Leased Premises or within existing outside trash enclosures. All entrances to
such outside trash


                                       12
<PAGE>   18

enclosures shall be kept closed, and waste shall be stored in such manner as not
to be visible from the exterior of such outside enclosures. Tenant shall cause
all of its waste to be regularly removed from the Property at Tenant's sole
cost. Tenant shall keep all fire corridors and mechanical equipment rooms in the
Leased Premises free and clear of all obstructions at all times.

        7.2. Utilities: Tenant shall promptly pay, as the same become due, all
charges for water, gas, electricity, telephone, sewer service, waste pick-up,

        7.3. Compliance with Rules, Regulations and Requirements: Landlord shall
comply with all rules, regulations and requirements promulgated by national,
state or local governmental agencies or utility suppliers concerning the use of
utility services, including any rationing, limitation or other control. Tenant
shall not be entitled to terminate this Lease nor to any abatement in rent by
reason of such compliance. Furthermore, Landlord shall be entitled to cooperate
voluntarily in a reasonable manner with the efforts of all governmental agencies
or utility suppliers in reducing energy or other resources consumption. Tenant
agrees at all times to cooperate fully with Landlord and to abide by all rules
and regulations and requirements which Landlord may prescribe in order to
maximize the efficient operation of the HVAC system and all other utility
systems.

                               REAL PROPERTY TAXES

        8.1. Real Property Taxes Defined: 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 or 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) 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 Property (as now constructed or as may at any time hereafter
be constructed, altered, or otherwise changed) or Landlord's interest therein;
the fixtures, equipment and other property of Landlord, real or personal, that
are an integral part of and located on the


                                       13
<PAGE>   19

Property; or the use of parking areas, public utilities, or energy within the
Property; (ii) all charges, levies or fees imposed by reason of environmental
regulation or other governmental control of the Property, 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 Lease Term the taxation or assessment of the
Property prevailing as of the Effective Date 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 Property of
Landlord's interest therein or (ii) on or measured by the gross receipts,
income, or rentals from the Property, on Landlord's business of leasing the
Property, or computing in any manner with respect to the operation of the
Property, 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
Property, then only that part of such Real Property Tax that is fairly allocable
to the Property 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, transfer, gift or franchise taxes of Landlord or
the federal or state net income tax imposed on Landlord's income from all
sources.

        8.2. Tenant's Obligation to Reimburse: As Additional Rent, Tenant shall
pay Tenant's Allocable Share of all Real Property Taxes (i) within ten (10) days
after being billed for the same by Landlord, or (ii) no later than ten (10) days
before such Real Property Tax becomes delinquent, whichever last occurs. If any
part of the Property is separately assessed for purposes of any Real Property
Tax, then Tenant shall pay that portion of such Real Property Tax as is fairly
allocable to the Leased Premises. If requested by Tenant in writing within
thirty (30) days of receipt of a bill for Tenant's allocated Share of Real
Property Taxes, Landlord shall furnish Tenant with such evidence as is
reasonably available to Landlord with respect to the amount of any Real Property
Tax which is part of such bill. Tenant may not withhold payment of such bill
pending receipt and/or review of such evidence. If any Lender requires Landlord
to impound Real Property Taxes on a periodic basis during the Lease Term, then
Tenant, on notice from Landlord indicating this requirement, shall pay a sum of
money toward its liability under this Article to Landlord on the same periodic
basis in accordance with the lender's requirements. Landlord shall impound the
Real Property Tax payments received from Tenant in accordance with requirements


                                       14
<PAGE>   20

of the Lender.

        8.3. Taxes on Tenant's Property: Tenant shall pay before delinquency any
and all taxes, assessments, license fees, and public charges levied, assessed,
or imposed against Tenant or Tenant's estate in this Lease or the property of
Tenant situated within the Leased Premises which become due during the Lease
Term. On demand by Landlord, Tenant shall furnish Landlord with satisfactory
evidence of these payments.

                                   ARTICLE 9

                                   INSURANCE

        9.1. Tenant's Insurance: Tenant shall maintain in full force and effect
during the Lease Term the following insurance:

                9.1.1. Tenant shall maintain a policy or policies of commercial
general liability insurance, including property damage, against liability for
personal injury, bodily injury, death, and damage to property occurring in or
about, or resulting from an occurrence in or about, the Leased Premises with
combined single limit coverage of not less than the amount of Tenant's Minimum
Liability Insurance set forth in paragraph 1.10. Such comprehensive general
liability insurance shall contain "fire legal" endorsement coverage and a
"contractual liability" endorsement insuring Tenant's performance of Tenant's
obligation to indemnify Landlord contained in paragraph 10.2. If Landlord's
Lender, insurance advisor or counsel reasonably determines at any time that the
amount of such coverage is not adequate, Tenant shall increase such coverage to
such amount as Landlord's Lender, insurance advisor or counsel reasonably deem
adequate, not to exceed the level of coverage then commonly carried by
comparable businesses similarly situated.

                9.1.2. Tenant shall maintain a policy or policies of fire and
property damage insurance in "all risk" form with a sprinkler leakage
endorsement (if the Building contains fire sprinklers) 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.

                9.1.3. Tenant shall maintain a policy or policies of worker's
compensation insurance and any other employee benefit insurance sufficient to
comply with all Laws.

                9.1.4. Landlord and such others it designates shall be named as
additional insureds on the policies of insurance described in subparagraphs
9.1.1 and 9.1.2 above. All insurance


                                       15
<PAGE>   21

required by this paragraph (i) shall be primary insurance which provides that
the insurer shall be liable for the full amount of the loss up to and including
the total amount of liability set forth in the declarations without the right of
contribution from any other insurance coverage of Landlord, (ii) shall be in a
form satisfactory to Landlord, (iii) shall be carried with companies reasonably
acceptable to Landlord, (iv) shall provide that such policies shall not be
subject to cancellation or change except after at least thirty (30) days prior
written notice to Landlord, and (v) shall not have a "deductible" in excess of
twenty-five thousand Dollars ($25,000.00) per occurrence. Copies of such policy
or policies, or duly executed certificates for them, together with satisfactory
evidence of the payment of the premium thereon shall be deposited with Landlord
prior to the time Tenant enters into possession of the Leased Premises and upon
renewal of such policies, but not less than thirty (30) days prior to the
expiration of the term of such coverage.

        9.2. Release and Waiver of Subrogation: The parties hereto release each
other, and their respective agents, employees, and contractors, from any claims
for injury to any persons or damage to property that are caused by or result
from risks insured against under any insurance policies carried by the parties
and in force at the time of such damage, but only to the extent such claims are
covered by such insurance. This release shall be in effect only so long as the
applicable insurance policies contain a clause to the effect that this release
shall not affect the right of the insured to recover under such policies. Each
party shall cause each insurance policy obtained by it to provide that the
insurance company waives all rights of recovery by way of subrogation against
either party in connection with any damage covered by such policy so long as
such waiver is available without unreasonable additional cost.

        9.3. Landlord's Real Property Insurance: Landlord shall pur- chase and
keep in force policy(ies) of insurance covering loss or damage to the Premises
by reason of fire (extended coverage), flood and/or earthquake (if available and
available at commercially reasonable costs in Landlord's sole discretion, or if
required by a lender) and those perils included within the classification of
"all risks" insurance (with sprinkler damage and other appropriate
endorsements), which insurance shall be in the amount of the full replacement
value of the Premises as determined by insurance company appraisers or
Landlord's insurance broker; plus Landlord's liability insurance; plus rental
income insurance in the amount of one hundred (100%) percent of up to twelve
(12) months Basic Rent (plus sums paid during such period as Additional Rent).
Such coverage shall exclude routine maintenance and repairs and incidental
damage caused by accidents or vandalism for which Tenant is responsible


                                       16
<PAGE>   22

under Section 9. Tenant agrees to pay to Landlord as Additional Rent in
accordance with Section 3.2(2) of this Lease the costs of such insurance
coverage, including the premiums and deductibles for any such coverage obtained
by Landlord; or, if Tenant does not lease the entire Building, then Tenant's
proportional share of the costs of such insurance coverage which shall be
allocated during the term of this Lease to the Premises by building square
footage. If such insurance cost is increased due to Tenant's particular use of
the Premises, Tenant agrees to pay to Landlord the full costs of such increase.
Tenant shall have no interest in nor any right to the proceeds of any insurance
procured by Landlord for or with respect to the Premises.

        10.1. Limitation on Landlord's Liability: Landlord shall not be liable
to Tenant, nor shall Tenant be entitled to any abatement of rent, for any injury
to Tenant, its agents, employees, contractors, or invitees; damage to Tenant's
property; or loss to Tenant's business resulting from any cause, including
without limitation any (i) failure, interruption or installation of any HVAC or
other utility system or service; (ii) failure to furnish or delay in furnishing
any utilities or services when such failure or delay is caused by acts of God or
the elements, labor disturbances of any character, any other accidents or other
conditions beyond the reasonable control of Landlord, or by the making of
repairs or improvements to the Leased Premises or Building; (iii) the
limitation, curtailment, rationing or restriction on the use of water or
electricity, gas or any other form of energy or any services or utility
whatsoever serving the Leased Premises or Building; (iv) vandalism or forcible
entry by unauthorized person; or (iv) penetration of water into or onto any
portion of the Leased Premises through roof leaks or otherwise. Notwithstanding
the foregoing, Landlord shall be liable for such injury, damage or loss which is
proximately caused by Landlord's active negligence or willful misconduct, but
only to the extent such injury, damage or loss is not covered by insurance
actually carried or required to be carried pursuant to this Lease.

        10.2. Limitation on Tenant's Recourse: Tenant expressly agrees that so
long as the Landlord under this Lease shall be and remains a corporation, a
trust, a partnership, a joint venture, an unincorporated association, or other
form of business entity, (i) the obligations of the Landlord under this Lease
shall not constitute personal obligations of the officers, directors, trustees,
partners, joint venturers, members, owners,


                                       17
<PAGE>   23

stockholders, or other principals or representatives of such business entity,
and (ii) Tenant shall have recourse only to the assets of such business entity
for the satisfaction of such obligations and not against the assets of such
officers, directors, trustees, partners, joint venturers, members, owners,
stockholders, principals, or representatives, other than to the extent of their
interest in the assets owned by such business entity.

        10.3. Indemnification of Landlord: Tenant shall hold harmless, indemnify
and defend Landlord, and its employees, agents, and contractors, with competent
counsel reasonably satisfactory to Landlord, from all liability, penalties,
losses, damages, costs, expenses, causes of action, claims and/or judgments
arising by reason of any death, bodily injury, personal injury or property
damage (i) resulting from any cause or causes whatsoever (other than the active
negligence or willful misconduct of Landlord) occurring in or about or resulting
from any occurrence in or about the Leased Premises during the Lease Term, or
(ii) resulting from the negligence or willful misconduct of Tenant, its agents,
employees and contractors, wherever the same may occur. The provisions of this
paragraph shall survive the expiration or termination of this Lease with respect
to any claims or liability occurring prior to such expiration or sooner
termination.

                                   ARTICLE 11

                            DAMAGE TO LEASED PREMISES

        11.1. Landlord's Duty to Restore: If the Leased Premises are damaged by
any Covered Peril (as hereinafter defined in Section 11.2.1) after the Effective
Date of this Lease, Landlord shall restore the Leased Premises unless the Lease
is terminated by Landlord pursuant to paragraph 11.2 or by Tenant pursuant to
paragraph 11.3. All insurance proceeds available from the fire and property
damage insurance carried by Landlord pursuant to paragraph 9.2 shall be paid to
and become the property of Landlord. All insurance proceeds available from
insurance carried by Tenant which covers loss to property that is Landlord's
property or would become Landlord's property on termination of this Lease shall
be paid to and become the property of Landlord. If this Lease is not so
terminated, then upon receipt of the insurance proceeds (if the loss is covered
by insurance) and the issuance of all necessary governmental permits, Landlord
shall commence and diligently prosecute to completion the restoration of the
Leased Premises, to the extent then allowed by Law, to substantially the same
condition in which the Leased Premises were immediately prior to such damage.
Landlord's obligation to restore shall be limited to the Leased


                                       18
<PAGE>   24

Premises and interior improvements constructed by Landlord as they existed as of
the Commencement Date, excluding any Leasehold Improvements, Trade Fixtures
and/or personal property constructed or installed by Tenant in the Leased
Premises. Tenant shall forthwith replace or fully repair all Leasehold
Improvements and Trade Fixtures installed by Tenant and existing at the time of
such damage or destruction.

        11.2. Landlord's Right to Terminate: Landlord shall have the option to
terminate this Lease in the event any of the following occurs, which option may
be exercised only by delivery to Tenant of a written notice of election to
terminate within thirty (30) days after the date of such damage.

                11.2.1. The Building is damaged by any peril covered by valid
and collectible insurance actually carried by Landlord and in force at the time
of such damage or destruction ("Covered Peril"), to such an extent that the
estimated cost to restore the Building equals or exceeds fifty percent (50%) of
the then replacement value thereof;

                11.2.2. The Building is damaged by any peril not covered by
valid and collectible insurance actually carried by Landlord and in force at the
time of such damage or destruction, to such an extent that the estimated cost to
restore the Building equals or exceeds twenty-five percent (25%) of the then
replacement value thereof;

                11.2.3. The Leased Premises are damaged by any Covered Peril
within six (6) months of the last day of the Lease Term to such an extent that
the estimated cost to restore equals or exceeds an amount equal to six (6) times
the Base Monthly Rent then due; provided, however, that Landlord may not
terminate this Lease pursuant to this subparagraph 11.2.3 if Tenant, at the time
of such damage, has an express written option to further extend the term of this
Lease and Tenant exercises such option to so further extend the Lease Term
within fifteen (15) days following the date of such damage; or

                11.2.4. The Building is damaged by any Covered Peril and,
because of the Laws then in force, (i) may not be restored at reasonable cost to
substantially the same condition in which it was prior to such damage, or (ii)
may not be used for the same use being made thereof before such damage whether
or not restored as required by this Article.

        11.3. Tenant's Right to Terminate: If the Leased Premises are damaged by
any peril and Landlord does not elect to terminate this Lease or is not entitled
to terminate this Lease pursuant to paragraph 11.2, then as soon as reasonably
practicable, Landlord


                                       19
<PAGE>   25

shall furnish Tenant with the written opinion of Landlord's architect or
construction consultant as to when the restoration work required of Landlord may
be completed. Tenant shall have the option to terminate this Lease in the event
any of the following occurs, which option may be exercised only by delivery to
Landlord of a written notice of election to terminate within seven (7) days
after Tenant receives from Landlord the estimate of the time needed to complete
such restoration:

                11.3.1. The Leased Premises are damaged by any peril and, in the
reasonable opinion of Landlord's architect or construction consultant, the
restoration of the Leased Premises cannot be substantially completed within one
hundred eighty (180) days after the date of such damage; or

                11.3.2. The Leased Premises are damaged by any peril within
twelve (12) months of the last day of the Lease Term and in the reasonable
opinion of Landlord's architect or construction consultant the restoration of
the Leased Premises cannot be substantially completed within ninety (90) days
after the date of such damage.

        11.4. Abatement of Rent: In the event of damage to the Leased Premises
which does not result in the termination of this Lease, the Base Monthly Rent
shall be temporarily abated during the period of restoration in proportion to
the degree to which Tenant's use of the Leased Premises is impaired by such
damage. Tenant shall not be entitled to any compensation or damages from
Landlord for loss of Tenant's property or any inconvenience or annoyance caused
by such damage or restoration. Tenant hereby waives the provisions of Section
1932, Subdivision 2, and Section 1933, Subdivision 4, of the California Civil
Code, and the provisions of any similar law hereinafter enacted.

                                   ARTICLE 12

                                  CONDEMNATION

        12.1. Taking of Leased Premises: If all or any part of the Leased
Premises are taken by means of: (i) any taking by the exercise of the power of
eminent domain, whether by legal proceedings or otherwise, (ii) a voluntary sale
or transfer by Landlord to any condemnor under threat of condemnation or while
legal proceedings for condemnation are pending, or (iii) any taking by inverse
condemnation (a "Condemnation"), then Landlord shall have the option to
terminate this Lease. If all or any part of the Leased Premises are taken by
Condemnation and the Leased Premises cannot be reconstructed within a reasonable
period of time and thereby made reasonably suitable for Tenant's continued
occupancy for the Permitted Use, then Tenant shall have the option to terminate
this Lease. Any such option to terminate


                                       20
<PAGE>   26

by either Landlord or Tenant must be exercised within a reasonable period of
time, to be effective as of the date that possession of the Leased Premises is
taken by the condemnor.

        12.2. Restoration Following the Taking: If any part of the Leased
Premises is taken by Condemnation and this Lease is not terminated, then
Landlord shall make all repairs and alterations that are reasonably necessary to
make that which is not taken a complete architectural unit, but such work shall
not exceed the scope of the work done by Landlord in originally constructing the
Property.

        12.3. Abatement of Rent: Except in the case of a temporary taking, if
any portion of the Leased Premises is taken by Condemnation and this Lease is
not terminated, then as of the date possession is taken, the Base Monthly Rent
and Additional Rent shall be reduced in the same proportion that the floor area
of that part of the Leased Premises so taken (less any addition thereto by
reason of any reconstruction) bears to the original floor area of the Leased
Premises.

        12.4. Temporary Taking: If any portion of the Leased Premises is
temporarily taken by Condemnation for a period which either exceeds one (1) year
or which extends beyond the natural expiration of the Lease Term, then Landlord
and Tenant shall each independently have the option to terminate this Lease,
effective on the date possession is taken by the condemnor.

        12.5. Division of Condemnation Award: Any award made as a result of any
Condemnation of the Leased Premises shall belong to and be paid to Landlord, and
Tenant hereby assigns to Landlord all of its right, title and interest in any
such award; provided, however, that Tenant shall be entitled to receive any
Condemnation award that is made directly to Tenant (i) for the taking of
personal property or Trade Fixtures belonging to Tenant, (ii) for the
interruption of Tenant's business or its moving costs, (iii) for loss of
Tenant's goodwill, or (iv) for any temporary taking where this Lease is not
terminated as a result of such taking. The rights of Landlord and Tenant
regarding any Condemnation shall be determined as provided in this Article, and
each party hereby waives the provisions of Section 1265.130 of the California
Code of Civil Procedure and the provisions of any similar law hereinafter
enacted allowing either party to petition the Superior Court to terminate this
Lease in the event of a partial taking of the Leased Premises.

<PAGE>   27

        13.1. Events of Tenant's Default: Tenant shall be in default of its
obligations under this Lease if any of the following events shall occur:

                13.1.1. Tenant shall have failed to pay Base Monthly Rent or any
other rent or payment due Landlord when due within three (3) days after written
notice from Landlord identifying the breach; or

                13.1.2. Tenant shall have failed to perform any term, covenant,
or condition of this Lease except those requiring the payment of money, and
Tenant shall have failed to cure such breach within thirty (30) days after
written notice from Landlord specifying the nature of such breach where such
breach reasonably could be cured within said thirty (30) day period; provided,
that where such failure reasonably could not be cured within said thirty (30)
day period, that Tenant shall not be in default unless it has failed to commence
cure of such default promptly within said thirty (30) day period and thereafter
to continue to make diligent and reasonable efforts to cure such failure as soon
as practicable; or

                13.1.3. Tenant shall have made a general assignment of its
assets for the benefit of its creditors; or

                13.1.4. Tenant shall have sublet the Leased Premises or assigned
its interest in the Lease in violation of the provisions contained in Article
14, whether voluntarily or by operation of law; or

                13.1.5. Tenant shall have permitted the sequestration or
attachment of, or execution on, or the appointment of a custodian or receiver
with respect to, all or any substantial part of the property of Tenant or any
property essential to the conduct of Tenant's business and Tenant shall have
failed to obtain a return or release of such property within thirty (30) days
thereafter, or prior to sale pursuant to such sequestration, attachment or levy,
whichever is earlier; or

                13.1.6. Tenant shall have abandoned the Leased Premises; or

                13.1.7. A court shall have made or entered any decree or order
with respect to Tenant or Tenant shall have submitted to or sought a decree or
order (or a petition or pleading shall have been filed in connection therewith)
which: (i) grants or constitutes (or seeks) an order for relief, appointment of
a trustee, or confirmation of a reorganization plan under the bankruptcy laws of
the United States; (ii) approves as properly filed (or seeks such approval of) a
petition seeking liquidation


                                       22
<PAGE>   28

or reorganization under said bankruptcy laws or any other debtor's relief law or
statute of the United States or any state thereof; or (iii) otherwise directs
(or seeks) the winding up or liquidation of Tenant; and such petition, decree or
order shall have continued in effect for a period of thirty (30) or more days.

        13.2. Landlord's Remedies: In the event of any default by Tenant,
Landlord shall have the following remedies, in addition to all other rights and
remedies provided by any Law or otherwise provided in this Lease, to which
Landlord may resort cumulatively, or in the alternative:

                13.2.1. Landlord may, at Landlord's election, keep this Lease in
effect and enforce by an action at law or in equity all of its rights and
remedies under the Lease, including (i) the right to recover the rent and other
sums as they become due by appropriate legal action, (ii) the right to make
payments required of Tenant or perform Tenant's obligations and be reimbursed by
Tenant for the cost thereof with interest at the Agreed Interest Rate from the
date the sum is paid by Landlord until Landlord is reimbursed by Tenant, and
(iii) the remedies of injunctive relief and specific enforcement to compel
Tenant to perform its obligations under this Lease.

                13.2.2. Landlord may, at Landlord's election, terminate this
Lease by giving Tenant written notice of termination, in which event this Lease
shall terminate on the date set forth for termination in such notice. Any
termination under this subparagraph shall not relieve Tenant from its obligation
to pay any sums then due Landlord or from any claim against Tenant for damages
or rent previously accrued or then accruing. In no event shall any one or more
of the following actions by Landlord, in the absence of a written election by
Landlord to terminate this Lease, constitute a termination of this Lease:

                        A. Appointment of a receiver or keeper in order to
protect Landlord's interest hereunder;

                        B. Consent to any subletting of the Leased Premises or
assignment of this Lease by Tenant, whether pursuant to the provisions hereof or
otherwise; or

                        C. Any other action by Landlord or Landlord's agents
intended to mitigate the adverse effects of any breach of this Lease by Tenant,
including without limitation any action taken to maintain and preserve the
Leased Premises or any action taken to relet the Leased Premises or any portions
thereof, for the account of Tenant and in the name of Tenant.


                                       23
<PAGE>   29

                13.2.3. In the event Tenant breaches this Lease and abandons the
Leased Premises, this Lease shall not terminate unless Landlord gives Tenant
written notice of its election to so terminate this Lease. No act by or on
behalf of Landlord intended to mitigate the adverse effect of such breach,
including those described by subparagraphs 13.2.2 A, B and C immediately
preceding, shall constitute a termination of Tenant's right to possession unless
Landlord gives Tenant written notice of termination. Should Landlord not
terminate this Lease by giving Tenant written notice, Landlord may enforce all
its rights and remedies under this Lease, including the right to recover the
rent as it becomes due under the Lease as provided in California Civil Code
Section 1951.4, as in effect on the Effective Date of this Lease.

                13.2.4. In the event Landlord terminates this Lease, Landlord
shall be entitled, at Landlord's election, to damages in an amount as set forth
in California Civil Code Section 1951.2 as in effect on the Effective Date of
this Lease. For purposes of computing damages pursuant to Section 1951.2, (i)
the Agreed Interest Rate shall be used where permitted, and (ii) rent due under
this Lease shall include Base Monthly Rent and all other rent hereunder,
prorated on a monthly basis where necessary to compute such damages. Such
damages shall include without limitation:

                        A. The worth at the time of award of the amount by which
the unpaid rent for the balance of the term after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided,
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of award plus one percent (1%); and

                        B. Any other amount necessary to compensate Landlord for
all detriment proximately caused by Tenant's failure to perform Tenant's
obligations under this Lease, or which in the ordinary course of things would be
likely to result therefrom, including, without limitation, the following: (i)
expenses for cleaning, repairing or restoring the Leased Premises; (ii) expenses
for altering, remodeling or otherwise improving the Leased Premises for the
purpose of reletting, including installation of leasehold improvements (whether
such installation be funded by a reduction of rent, direct payment or allowance
to a new tenant, or otherwise); (iii) broker's fees, advertising costs and other
expenses of reletting the Leased Premises; (iv) costs of carrying the Leased
Premises, such as taxes, insurance premiums, utilities, and security
precautions; (v) expenses in retaking possession of the Leased Premises; and
(vi) attorneys' fees and court costs incurred by Landlord in retaking possession


                                       24
<PAGE>   30

of the Leased Premises and in re-leasing the Leased Premises or otherwise
incurred as a result of Tenant's default.

                        C. For purposes of this Article, the rent due for any
calendar month after which Tenant has terminated the operation of its business
as herein specified or has abandoned the Leased Premises shall be deemed to be
the average monthly rent, including the Base Monthly Rent and all additional
rent hereunder, which were due for the twelve (l2) month period immediately
prior to such termination or for such shorter period of time as this Lease shall
have been in effect.

                13.2.5. Nothing in this paragraph shall limit Landlord's right
to indemnification from Tenant as provided in paragraph 10.2.

        13.3. Landlord's Default and Tenant's Remedies: In the event Landlord
fails to perform any of its obligations under this Lease and fails to cure such
default within thirty (30) days after written notice from Tenant specifying the
nature of such default where such default could reasonably be cured within said
thirty (30) day period, or fails to commence such cure within said thirty (30)
day period and thereafter continuously with due diligence prosecute such cure to
completion where such default could not reasonably be cured within said thirty
(30) day period, then Tenant shall have the following remedies only:

                13.3.1. Tenant may proceed in equity or at law to compel
Landlord to perform its obligations and/or to recover damages proximately caused
by such failure to perform (except to the extent Tenant has waived its right to
damages resulting from injury to person or damage to property as provided
herein).

                13.3.2. Tenant, at its option, may cure any default of Landlord
at Landlord's cost. If Tenant at any time by reason of Landlord's default
reasonably pays any sum or does any act that requires the payment of any sum,
the sum paid by Tenant shall be immediately due from Landlord to Tenant at the
time the sum is paid, and shall bear interest at the Agreed Interest Rate from
the date the sum is paid by Tenant until Tenant is reimbursed by Landlord.

                13.3.3. Tenant waives the provisions of Sections 1932(1), 1941,
and 1942 of the California Civil Code and/or any similar or successor law
regarding Tenant's right to terminate this Lease or to make repairs and deduct
the expenses of such repairs from the rent due under the Lease. Tenant hereby
waives any right of redemption or relief from forfeiture under the laws of the
State of California, or under any other present or future law, in the event
Tenant is evicted or Landlord takes possession


                                       25
<PAGE>   31

of the Leased Premises by reason of any default by Tenant.

        13.4. Waiver: One party's consent to or approval of any act by the other
party requiring the first party's consent or approval shall not be deemed to
waive or render unnecessary the first party's consent to or approval of any
subsequent similar act by the other party. The receipt by Landlord of any rent
or payment with or without knowledge of the breach of any other provision hereof
shall not be deemed a waiver of any such breach unless such waiver is in writing
and signed by Landlord. No delay or omission in the exercise of any right or
remedy accruing to either party upon any breach by the other party under this
Lease shall impair such right or remedy or be construed as a waiver of any such
breach theretofore or hereafter occurring. The waiver by either party of any
breach of any provision of this Lease shall not be deemed to be a waiver of any
subsequent breach of the same or any other provisions herein contained.

                                   ASSIGNMENT

        14.1. By Tenant: Tenant shall not sublet the Leased Premises or assign
or encumber its interest in this Lease, whether voluntarily or by operation of
law without Landlord's prior written consent, which consent shall not be
unreasonably withheld. In this regard:

                14.1.1. Any attempted subletting, assignment, or encumbrance
without Landlord's prior consent shall be voidable and, at Landlord's election,
shall constitute a default.

                14.1.2. Tenant agrees to reimburse Landlord all reasonable costs
and attorneys fees incurred by Landlord in conjunction with the processing and
documentation of any such requested subletting, assignment or encumbrance, none
of which shall be effective until Tenant shall have paid such costs and fees.

                14.1.3. Consent by Landlord to one or more assignments or
encumbrances of this Lease or to one or more sublettings of the Leased Premises
shall not be deemed to be a consent to any subsequent assignment, encumbrances,
or subletting.

                14.1.4. No subletting or assignment, even with the consent of
Landlord, shall relieve Tenant of its personal and primary obligation to pay the
rent and to perform all of the other obligations to be performed by Tenant
hereunder. The acceptance of rent by Landlord from any person shall not be
deemed to be a waiver by Landlord of any provision of this Lease or to be a
consent to any assignment or subletting.

                14.1.5. If Tenant is a corporation, any dissolution, merger,
consolidation, or other reorganization of Tenant, or the sale or other transfer
in a single transaction during the Lease Term of a controlling percentage of the
capital stock of Tenant, shall be deemed a voluntary assignment of Tenant's
interest in this Lease. The phrase "controlling percentage" means the ownership
of and the right to vote stock possessing more than fifty percent (50%) of the
total combined voting power of all classes of Tenant's capital stock issued,
outstanding and entitled to vote for the election of directors. If Tenant is a
partnership, a withdrawal or change, voluntary, involuntary or by operation of
law, of any general partner, or the dissolution of the partnership, shall be
deemed a voluntary


                                       27
<PAGE>   33

assignment.

                14.1.6. If Tenant assigns its interest in this Lease in
accordance with this Article, then Tenant shall pay to Landlord fifty percent
(50%) of all net consideration received by Tenant as a result of such assignment
as and when received by Tenant. If Tenant sublets all or part of the Leased
Premises in accordance with this Article, then Tenant shall pay to Landlord
fifty percent (50%) of the positive difference, if any, between (i) all rent and
other consideration paid by the subtenant to Tenant less (ii) all costs incurred
by Tenant incident to the sublease agreement (including an amount equal to the
resulting product of the rent payable hereunder to Landlord by Tenant during the
time period covered by such payments by the subtenant times a fraction whose
numerator is the leasable area of that portion of the Leased Premises so sublet
and whose denominator is Tenant's Gross Leasable Area). Said consideration shall
be payable to Landlord on the same basis, whether periodic or in lump sum, that
such consideration is paid to Tenant by its subtenant, and, in calculating
Landlord's share of any periodic payments, all costs incurred by Tenant incident
to the sublease agreement shall be amortized over the term of the sublease.
Immediately following its execution, Tenant shall deliver to Landlord a true
copy of any permitted assignment or sublease. At the time Tenant makes any
payment to Landlord required by this Subparagraph, Tenant shall deliver an
itemized statement of the method by which the amount due Landlord was
calculated, certified by Tenant as true and correct. Landlord shall have the
right to inspect Tenant's books and records relating to the payments due
pursuant to this subparagraph.

                14.1.7. Notwithstanding the provisions of para. 14.1.through
14.1.6. to the contrary, Tenant may, without Landlord's consent, sublet all or
any portion of the Premises or assign the Lease to (i) a subsidiary, parent,
affiliate, division or corporation controlled by or under common control with
Tenant or (ii) a successor corporation related to Tenant by merger,
consolidation, reorganization or government action. However, no such subletting
or assignment, even without the consent of Landlord, shall relieve Tenant of its
primary obligation to pay rent and perform all of the other obligations to be
performed by Tenant hereunder for which it will remain liable.

        15.1. Surrender of the Leased Premises: Immediately prior to the
expiration or upon the sooner termination of this Lease, Tenant shall remove all

Date, reasonable wear and tear excepted, with all interior walls cleaned, all
carpets shampooed and cleaned, all HVAC equipment within the Leased Premises in

or electrical system within the Leased Premises for the purpose of determining
whether they have been properly maintained by Tenant, and Tenant shall pay the
cost thereof within ten (l0) days after receipt of a statement therefore from

to Landlord for all costs incurred by Landlord in returning the Leased Premises
to the required condition, plus interest on all costs incurred at the Agreed
Interest Rate. Tenant shall indemnify Landlord against loss or liability

losses to Landlord due to lost opportunities to lease to succeeding tenants.

the Lease Term 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 such expiration 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 Base Monthly Rent
shall be


                                       29

Tenant; (iv) showing the Leased Premises to prospective purchasers, mortgagees
or tenants; (v) making necessary alterations, additions, or repairs; (vi)

necessary and proper to open the doors of the Leased Premises in an emergency.
Any entry to the Leased Premises or portions thereof 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 Leased
Premises, or an eviction, actual or constructive, of Tenant from the Leased
Premises or any portion thereof.

                              MORTGAGES & TRANSFER

        17.1. Subordination: This Lease is subject and subordinate to all
underlying ground leases, mortgages and deeds of trust which affect the Property
and are of public record as of the Effective Date of this Lease, and to all
renewals, modifications, consolidations, replacements and extensions thereof.
However, if the lessor under any such lease or any Lender holding such mortgage
or deed of trust shall advise Landlord that it desires or requires this Lease to
be prior and superior thereto, then, upon written request of Landlord to Tenant,
Tenant shall promptly execute, acknowledge and deliver any and all documents or
instruments which Landlord or such lessor or Lender deems necessary or desirable
to make this Lease prior thereto. At Landlord's election, this Lease shall
become and thereafter remain subject and subordinate to any and all future
ground leases, mortgages or deeds of trust affecting the Property which may
hereafter be executed and placed of public record after the Effective Date of
this Lease, or any renewals, modifications, consolidations, replacements or
extensions thereof, for the full


                                       31
<PAGE>   37

amount of all advances made or to be made thereunder and without regard to the
time or character of such advances, so long as the lessor of such ground lease
or the Lender holding the mortgage or deed of trust to which this Lease is to be
subordinated agrees that it will recognize Tenant's rights under this Lease and
not disturb its quiet possession of the Leased Premises so long as Tenant is not
in default hereunder. Tenant agrees, within ten (l0) days after Landlord's
written request therefor to execute, acknowledge and deliver upon request of
Landlord any and all documents or instruments requested by Landlord or such
lessor or mortgage holder(s) as may be necessary or proper to assure the
subordination of this Lease to any such ground lease, mortgage or deed of trust.

        17.2. Tenant's Attornment: Tenant shall attorn (i) to any purchaser of
the Building or Property at any foreclosure sale or private sale conducted
pursuant to any security instrument encumbering the Building and/or the
Property, (ii) to any grantee or transferee designated in any deed given in lieu
of foreclosure, or (iii) to the lessor under any underlying ground lease should
such ground lease be terminated.

        17.3. Mortgagee Protection: In the event of any default on the part of
Landlord, Tenant will give notice by registered mail to any Lender or lessor
under any underlying ground lease whose name has been provided to Tenant and
shall offer such Lender or lessor a reasonable opportunity to cure the default,
including time to obtain possession of the Leased Premises by power of sale or
judicial foreclosure or other appropriate legal proceedings, if such should
prove necessary to effect a cure.

        17.4. Estoppel Certificates: At all times during the Lease Term, Tenant
agrees, following any request by Landlord, to promptly execute and deliver to
Landlord an estoppel certificate, except as otherwise set forth in such request,
(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, (ii) stating the date to
which the rent and other charges are paid in advance, if any, (iii)
acknowledging that there is not, to Tenant's knowledge, any uncured defaults on
the part of Landlord hereunder, and if there are uncured defaults on the part of
Landlord, stating the nature of such uncured defaults, and (iv) certifying such
other information about the Lease as may be reasonably required by Landlord.
Tenant's failure to deliver an estoppel certificate within ten (l0) days after
delivery of Landlord's request therefore shall be a conclusive admission by
Tenant that, as of the date of the request for such statement, (i) this Lease is
unmodified except as may be represented by Landlord in said request and is in
full force and effect, (ii)

                                       32
<PAGE>   38

there are no uncured defaults in Landlord's performance, and (iii) no rent has
been paid in advance.

        17.5. Financial Statements: At any time during the Lease Term, Tenant
shall, upon fifteen (15) days' prior written notice from Landlord, provide
Tenant's most recent financial statement and financial statements covering the
twenty-four (24) month period prior to the date of such most recent financial
statements to Landlord and to any existing Lender, potential Lender or buyer or
potential buyer of the Premises. Such statements shall be prepared in accordance
with generally accepted accounting principles and, if such is the normal
practice of Tenant, shall be audited by an independent certified public
accountant.

value shall be $100,000,000 or more.

        20.2. Notice of Availability of First Offer Space. If the First Offer
Space becomes available at any time after the Effective Date of this Lease and
before the expiration or earlier termination of this right of First Offer Space,
then Landlord shall notify Tenant in writing of the availability of the First
Offer Space.

        20.3. Exercise of Right of First Offer. If Tenant, within two (2) weeks
after receipt of Landlord's notice which shall be given no later than March 31,
2002, indicates in writing its agreement to lease such First Offer Space, then
Landlord and Tenant shall enter into a lease agreement (the "Second Lease")
whereby Landlord shall lease to Tenant and Tenant shall lease


                                       41
<PAGE>   47

from Landlord such First Offer Space on the terms stated in Landlord's written
notice which shall include the following essential business terms: (1) Five (5)
year lease term; (2) Basic Monthly Rent to commence at fair market rent for
similar buildings in the immediate vicinity at the date of such election; (3)
First Offer Space to be taken "AS-IS"; (4) Security Deposit to be in amount of
first month's Basic Rent; and (5) lease to be on Landlord's standard, single
tenant, triple net lease form similar in form to the instant Lease.

        20.4. Determination of Fair Market Rent. In the event it becomes
necessary to determine by appraisal the fair market rent of the First Offer
Space for the purpose of establishing the Base Monthly Rent during the five (5)
year lease term, then such fair market monthly rent shall be determined by three
(3) real estate appraisers, all of whom shall be members of the American
Institute of Real Estate Appraisers with not less than five (5) years experience
appraising real property (other than residential or agricultural property)
located in Santa Clara County, California, in accordance with the following
procedures:

                (1) The party demanding an appraisal (the "Notifying Party")
shall notify the other party (the "Non-Notifying Party") thereof by delivering a
written demand for appraisal, which demand, to be effective, must give the name,
address, and qualifications of an appraiser selected by the Notifying Party.
Within ten (10) days of receipt of said demand, the Non-Notifying Party shall
select its appraiser and notify the Notifying Party, in writing, of the name,
address, and qualifications of an appraiser selected by it. Failure by the
Non-Notifying Party to select a qualified appraiser within said ten (10) day
period shall be deemed a waiver of its right to select a second appraiser on its
own behalf and the Notifying Party shall select a second appraiser on behalf of
the Non-Notifying Party within five (5) days after the expiration of said ten
(10) day period. Within ten (10) days from the date the second appraiser shall
have been appointed, the two (2) appraisers so selected shall appoint a third
appraiser. If the two appraisers fail to select a third qualified appraiser, the
third appraiser shall be selected by the American Arbitration Association or if
it shall refuse to perform this function, then at the request of either Landlord
or Tenant, such third appraiser shall be promptly appointed by the then
Presiding Judge of the Superior Court of the State of California for the County
of Santa Clara.

                (2) The three (3) appraisers so selected shall meet in
Sunnyvale, California, not later than twenty (20) days following the selection
of the third appraiser. At said meeting the appraisers so selected shall attempt
to determine the fair market monthly rent of the Premises for the option period
in question


                                       42
<PAGE>   48

(including the timing and amount of periodic increases).

                (3) If the appraisers so selected are unable to complete their
determinations in one meeting, they may continue to consult at such times as
they deem necessary for a fifteen (15) day period from the date of the first
meeting, in an attempt to have at least two (2) of them agree. If, at the
initial meeting or at any time during said fifteen (15) day period, two (2) or
more of the appraisers so selected agree on the fair market rent of the Leased
Premises, such agreement shall be determinative and binding on the parties
hereto, and the agreeing appraisers shall, in simple letter form executed by the
agreeing appraisers, forthwith notify both Landlord and Tenant of the amount set
by such agreement.

                (4) If two (2) or more appraisers do not so agree within said
fifteen (15) day period, then each appraiser shall, within five (5) days after
the expiration of said fifteen (15) day period, submit his independent appraisal
in simple letter form to Landlord and Tenant stating his determination of the
fair market rent of the Promises for the option period in question. The parties
shall then determine the fair market rent for the Premises by determining the
average of the fair market rent set by each of the appraisers. However, if the
lowest appraisal is less than eighty-five percent (85%) of the middle appraisal
then such lowest appraisal shall be disregarded and/or if the highest appraisal
is greater than one hundred fifteen percent (115%) of the middle appraisal then
such highest appraisal shall be disregarded. If the fair market rent set by any
appraisal is so disregarded, then the average shall be determined by computing
the average set by the other appraisals that have not been disregarded.

                (5) Nothing contained herein shall prevent Landlord and Tenant
from jointly selecting a single appraiser to determine the fair market rent of
the Promises, in which event the determination of such appraisal shall be
conclusively deemed the fair market rent of the Premises.

                (6) Each party shall bear the fees and expenses of the appraiser
selected by or for it, and the fees and expenses of the third appraiser (or the
joint appraiser if one joint appraiser if one joint appraiser is used) shall be
borne fifty percent (50%) by Landlord and fifty percent (50%) by Tenant.

        20.5. Landlord's Right to Lease. If Tenant does not indicate in writing
its agreement to enter into the Second Lease on the terms contained in
Landlord's written notice within the allowed period of time, then Tenant's Right
of First Offer shall terminate and Landlord thereafter shall have the right to
lease


                                       43
<PAGE>   49

such space to the current tenant or any other prospective tenant.

                20.6. First Offer Space. The term "First Offer Space" shall mean
that building commonly described as 740 Arques Avenue, Sunnyvale, California,
consisting of approx. 20,000 s.f. Such First Offer Space is currently being
leased by Landlord to, and is occupied by, Navigational Technologies pursuant to
a lease with an expiration date of October 31, 2002 which lease does not contain
an option to extend the term thereof beyond October 31, 2002.

        20.7. Termination. The provisions of this Article 20 shall terminate
upon the earliest of the following to happen: (i) the expiration or earlier
termination of the Lease, or except as provided in Paragraphs 14.1.5 and 14.1.7
of the Lease (ii) any assignment by Tenant of its interest in this Lease or
subletting by Tenant of substantially all of the Premises for substantially all
of the remainder of the Lease Term.

                                   ARTICLE 21

                             OPTION TO EXTEND LEASE

        21.1. Option to Extend Lease Term. In the event Tenant exercises its
Right of First Offer as set forth in Article 20 herein above, then and only
then, Landlord grants to Tenant an option to extend the Lease Term for a period
required to make this Lease conterminous with the term of the Second Lease for
the Right of First Offer Space term on the following terms and conditions:

                21.1.l. Tenant must give Landlord notice in writing of its
exercise of the option in question no later than ninety (90) days before the
date the Lease Term would end but for said exercise and Tenant must exercise
such option, if at all, for the entire Leased Premises than occupied by Tenant.
Tenant's option rights shall terminate as to any space for which the option to
extend is not exercised.

                21.1.2. Tenant may not extend the Lease Term pursuant to any
option granted by this paragraph if Tenant is materially in default beyond any
applicable cure period as of the date of exercise of the option in question or
as to the date this Lease would have been terminated but for said exercise.

                21.1.3. All terms, covenants, and conditions of this Lease shall
apply during the option period, except that the Base Monthly Rent for the option
period shall be determined as provided in paragraph 20.1.4.


                                       44
<PAGE>   50

                21.1.4. The Base Monthly Rent for the option period shall be the
Monthly Basic Rent payable for the last month of the previous Lease Term with
annual increases of four (4%) percent per annum calculated in the same manner as
the Base Monthly Rent in this Lease.

                21.1.5. The option rights of Tenant under this Article 21, and
the Extended Term thereunder, are granted for Tenant's personal benefit and may
not be assigned or transferred by Tenant, except as provided in Paragraphs
14.1.5 and 14.1.7 of the Lease. In the event that Landlord consents to a
sublease or assignment under Article 14, the option granted herein and any
Extended Term thereunder shall be void and of no force and effect, whether or
not Tenant shall have purported to exercise such option prior to such assignment
or sublease.


        IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease with
the intent to be legally bound thereby, to be effective as of the Effective Date
of this Lease.

Tenant agree that the following terms are part of the Lease.

           1. Purpose of Improvement Agreement: The purpose of this Improvement

of the Interior Improvements; and (v) the cost of payment and performance bonds
obtained by Tenant or Project Contractor to assure completion of the Interior
Improvements. The parties acknowledge that the City of Sunnyvale imposes certain
taxes as a condition to the issuance of building permits in certain

consistent with the Interior Plan) in the following manner: (i) Tenant shall
cause the Project Architect to prepare such plans and specifications for
Landlord's approval; (ii) as Preliminary Plans and Specifications for the
Interior, Improvements are developed by Tenant, they shall be submitted to
Landlord for approval; (iii) Landlord shall have five (5) working days after
receipt of any information from Tenant regarding the Preliminary Plans and
Specifications to approve such information or respond specifically in writing as
to why and in what particular regard the information so submitted is not
acceptable, and a failure to so respond shall be deemed Landlord's approval of
the information submitted; and (iv) if Landlord proposes changes to the
Preliminary Plans and Specifications, Landlord and Tenant shall confer in good
faith to complete development and approval of the Preliminary Plans and
specifications as soon as reasonably practicable. The Preliminary Plans And
Specifications so developed and approved by Landlord and Tenant pursuant to this
subsection are referred to herein as the "Approved Preliminary Plans."

               b. Development of Final Plans for Interior Improvements. As soon
as possible after Landlord and Tenant have agreed upon the Approved Preliminary
Plans, Tenant shall cause such Project Architect to prepare and deliver to
Landlord for Landlord's. approval, copies of Final Plans, Specifications and
Working Drawings for the Interior Improvements that are consistent with and/or
logical evolutions from the Approved Preliminary Plans. Landlord shall have ten
(10) working days after such delivery to reasonably approve such Final Plans,
Specifications and Working Drawings in writing or to respond in writing
specifying the exact changes required for approval, and a failure by Landlord to
so respond in writing shall be deemed its approval of the matters submitted to
it. Tenant shall then cause such changes to be made and resubmit the same to
Landlord for its approval as aforementioned, which approval Landlord agrees not
to unreasonably withhold or delay. The parties shall at all times act in good
faith to reach agreement on Final Plans, specifications and Working Drawings for
the Interior




                                       50
<PAGE>   56

Improvements, with each party using its best efforts so that the Final Plans,
Specifications, and Working Drawings will be completed on or before October 13,
2000. As soon as so approved by Landlord, Tenant shall submit such Final Plans,
Specifications, and Working Drawings to all appropriate governmental agencies
for approval. If any changes are required by such governmental agencies, Tenant
shall report back to Landlord and the parties shall confer and make such changes
as are necessary to satisfy the requirements of such governmental agencies. As
soon as all such governmental approvals have been obtained, four (4) copies of
such Final Plans, Specifications, and Working Drawings shall be initialed and
dated by Landlord and Tenant. The Final Plans, Specifications, and Working
Drawings so approved, and all change orders specifically permitted by this Lease
shall be referred to herein as the "Final Approved Interior Plans." The parties
acknowledge that the commencement of the terms of this Lease depends upon when
the Interior Improvements are completed and that such completion depends in part
upon Tenant's submission of its requirements for such improvements and its
response to approving plans prepared by Tenant. The parties agree to each use
their best efforts to process the preparation and approval of plans for the
Interior Improvements within the schedule set forth herein.

               c. Construction Contract: Landlord and Tenant anticipate that the
Interior Improvements per EXHIBIT "D" shall be constructed by Hollander Smith,
Inc. (hereinafter the "Project Contractor").

               d. Commencement and Completion for the Interior Improvements: As
soon as the Approved Specifications have been developed as provided above, all
necessary governmental approvals have been obtained and the Tenant has entered
into a general construction contract with the Project Contractor, then Tenant
shall thereafter commence construction of the Interior Improvements and shall
diligently prosecute such construction to completion, using its best efforts so
that the Interior Improvements may be Substantially Completed by the "Scheduled
Commencement Date."

           4. Changes to Approved Specifications: Neither Landlord nor Tenant
shall have the right to order extra work or change orders to the Approved
Specifications described in EXHIBIT "D" without the prior written consent of the
other. All extra work or change orders requested by either Landlord or Tenant
shall be made in writing, shall specify any added or reduced cost and/or
construction time resulting therefrom, and shall become effective and a part of
the Approved Specifications once approved in writing by both parties. If a
change order-requested by Tenant results or causes an increase in the Interior
Improvements Costs above the amount of the Tenant Improvement



                                       51
<PAGE>   57

Allowance, then Tenant shall pay the amount of such increase over the Tenant
Improvement Allowance caused by the change order requested by Tenant at the time
the change order is approved by both Landlord and Tenant. If a change order
results in an increase in the amount of construction time needed by Tenant to
complete the Interior Improvements, paragraph 5 hereof may apply.

           5. Delay in completion Caused by Tenant: The parties hereto
acknowledge that the date on which Tenant's obligation to pay the Base Monthly
Rent and the Additional Rent would otherwise commence may be delayed because of
(i) Tenant's failure to submit necessary information to Landlord when required,
(ii) Tenant's failure to promptly develop and submit the plans for the Interior
Improvements, (iii) any act by Tenant which interferes with or delays the
completion of the plans for the Interior Improvements or Landlord's construction
work, (iv) change orders requested by Tenant and approved by Landlord, or (v)
special materials or equipment ordered or specified by Tenant that cannot be
obtained by Tenant at normal cost within a reasonable period of time because of
limited availability. It is the intent of the parties hereto that the
commencement of Tenant's obligation to pay the Base Monthly Rent and all
Additional Rent not be delayed by any of such causes or by any other act of
Tenant, and in the event it is go delayed, Tenant's obligation to pay the base
Monthly Rent and all Additional Rent shall commence as of the date it would
otherwise have commenced absent delay caused by Tenant, provided that within a
reasonable period of time after learning of the occurrence of the cause of any
such delay, Tenant notifies Landlord in writing of the fact that such delay has
occurred and the known or anticipated extent of any such delay.

           6. Delivery of Possession and Acceptance Agreement. As soon as the
Interior Improvements are Substantially Completed, Landlord and Tenant shall
together walk through the Premises and inspect all Interior Improvements so
completed using reasonable efforts to discover all uncompleted or defective
construction in the Interior Improvements. After such inspection has been
completed, each party shall sign an Acceptance Agreement in the form attached to
the Lease as EXHIBIT "E", which shall state the Commencement Date and the Base
Monthly Rent. As soon as such inspection has been completed and such acceptance
agreement executed, Landlord shall deliver possession of the Premises to Tenant.
Landlord shall have no obligation to deliver possession of the Premises to
Tenant until the execution of the acceptance agreement has been completed.
Tenant's taking possession of any part of the Premises shall be deemed to be an
acceptance by Tenant of the Premises in accordance with the terms of the Lease
except latent defects that could not reasonable have been



                                       52
<PAGE>   58

discovered by Tenant. Notwithstanding anything contained herein, Tenant's
obligation to pay the Base Monthly Rent and Additional Rent shall commence as
provided in the Lease, regardless of whether Tenant completes such inspection or
executes such acceptance agreement.

           7. Standard of construction and Warranty: Tenant hereby warrants that
the Interior Improvements shall be constructed substantially in accordance with
the Approved Specifications (as modified by change orders approved by Landlord
and Tenant), all Private Restrictions and all Laws, in a good and workmanlike
manner, and all materials and equipment furnished shall conform to such final
plans and shall be new and otherwise of good quality. The foregoing warranty
shall be subject to, and limited by, the following:

               a. Once Tenant is notified in-writing of any breach of the
above-described warranty, Tenant shall promptly commence the cure of such breach
and complete such cure with diligence at Landlord's sole cost and expense.

               b. Tenant's liability pursuant to such warranty shall be limited
to the cost of correcting the defect or other matter in question. In no event
shall Landlord be liable to Tenant for any damages or liability incurred by
Tenant as a result of such defect or other matter, including without limitation
damages resulting from any loss of business by Tenant or other consequential
damages.

               c. Upon request by Landlord, Tenant shall inform Landlord of all
written construction and equipment warranties existing in favor of Tenant which
affect the Interior Improvements. Landlord shall cooperate with Tenant in
enforcing such warranties and in bringing any suit that may be necessary to
enforce liability-with regard to any defect for which Landlord is not
responsible pursuant to this paragraph so long as Tenant pays all costs
reasonably incurred by Landlord in so acting.

               d. Tenant makes no other express or implied warranty with respect
to the design, construction or operation of the Interior Improvements except as
set forth in this paragraph.
