1. USE  Tenant shall use the Premises only in conformance with applicable
governmental laws, regulations, rules and ordinances for the purpose of general

<PAGE>   2
3. POSSESSION. If Landlord, for any reason whatsoever, cannot deliver possession
of said premises to Tenant at the commencement of the said term, as hereinbefore
specified, this Lease shall not be void or voidable; no obligation of Tenant
shall be affected thereby; nor shall Landlord or Landlord's agents be liable to
Tenant for any loss or damage resulting therefrom; but in that event the
commencement and termination dates of the Lease, and all other dates affected
thereby shall be revised to conform to the date of Landlord's delivery of
possession, as specified in Paragraph 2B, above. The above is, however, subject
to the provision that the period of delay of delivery of the Premises shall not
exceed 60 days from the commencement date herein (except those delays caused by
Acts of God, strikes, war, utilities, governmental bodies, weather, unavailable
materials, and delays beyond Landlord's control shall be excluded in calculating
such period) in which instance Tenant, at its option, may, by written notice to
Landlord, terminate this Lease.

4. RENT

   A. Basic Rent. Tenant agrees to pay to Landlord at such place as Landlord may
designate without deduction, offset, prior notice, or demand, and Landlord
agrees to accept as Basic Rent for the leased Premises the total sum of SIX
MILLION ONE HUNDRED FIFTEEN THOUSAND FIVE HUNDRED AND NO/100 Dollars
($6,115,500.00) in lawful money of the United States of America, payable as
follows:

   See Paragraph 39 for Basic Rent Schedule

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

   C. Late Charges. Notwithstanding any other provision of this Lease, if Tenant
is in default in the payment of rental as set forth in this Paragraph 4 when
due, or any part thereof, Tenant agrees to pay Landlord, in addition to the
delinquent rental due, a late charge for each rental payment in default ten (10)
days. Said late charge shall equal ten percent (10%) of each rental payment so
in default.

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

      (a) All Taxes relating to the Premises as set forth in Paragraph 9, and

      (b) All insurance premiums relating to the Premises, as set forth in
Paragraph 12, and

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

   The Additional Rent due hereunder shall be paid to Landlord or Landlord's
agent (i) within ten days for taxes and insurance and within thirty (30) days
for all other Additional Rent items after presentation of invoice from Landlord
or Landlord's agent setting forth such Additional Rent and/or (ii) at the option
of Landlord, Tenant shall pay to Landlord monthly, in advance, Tenant's prorata
share of an amount estimated by Landlord to be Landlord's approximate average
monthly expenditure for such Additional Rent items, which estimated amount shall
be reconciled within 120 days of the end of each calendar year or more
frequently if Landlord elects to do so at Landlord's sole and absolute
discretion as compared to Landlord's actual expenditure for said Additional Rent
items, with Tenant paying to Landlord, upon demand, any amount of actual
expenses expended by Landlord in excess of said estimated amount, or Landlord
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 which payment by Tenant shall be made within
thirty (30) days after delivery by Landlord to Tenant of a written
reconciliation identifying the amount to be paid. If a refund is due Tenant,
Landlord shall credit Tenant's account accordingly within thirty (30) days of
said reconciliation.

   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 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 A&P FAMILY INVESTMENTS, C/O PEERY/ARRILLAGA, 2560 MISSION
COLLEGE BLVD., SUITE 101, SANTA CLARA, CA 95054 or to such other person or to
such other place as Landlord may from time to time designate in writing.

*  F. Security Deposit. Concurrently with Tenant's execution of this Lease,
Tenant shall deposit with Landlord the sum of ONE HUNDRED THIRTY SEVEN THOUSAND
FIVE HUNDRED AND NO/100 Dollars ($137,500.00). Said sum shall be held by
Landlord as a Security Deposit for the faithful performance by Tenant of all of
the terms, covenants, and conditions of this Lease to be kept and performed by
Tenant during the term hereof. If Tenant defaults with respect to any provision
of this Lease, including, but not limited to, the provisions relating to the
payment of rent and any of the monetary sums due herewith, Landlord may (but
shall not be required to) use, apply or retain all or any part of this Security
Deposit for the payment of any other amount which Landlord may spend by reason
of Tenant's default or to compensate Landlord for

*  $68,750.00 cash due upon execution of this Lease.
   $68,750.00 Promissory Note due May 1, 1996.


                                  page 2 of 8
<PAGE>   3
any other loss or damage which Landlord may suffer by reason of Tenant's
default. If any portion of said Deposit is so used or applied, Tenant shall,
within ten (10) days after written demand therefor, deposit cash with landlord
in the amount sufficient to restore the Security Deposit to its original amount.
Tenant's failure to do so shall be a material breach of this Lease. Landlord
shall not be required to keep this Security Deposit separate from its general
funds, and Tenant shall not be entitled to interest on such Deposit. If Tenant
fully and faithfully performs every provision of this Lease to be performed by
it, the Security Deposit or any balance thereof shall be returned to Tenant (or
at Landlord's option, to the last assignee of Tenant's interest hereunder) at
the expiration of the Lease term and after Tenant has vacated the Premises. In
the event of termination of Landlord's interest in this Lease, Landlord shall
transfer said Deposit to Landlord's successor in interest whereupon Tenant
agrees to release Landlord from liability for the return of such Deposit or the
accounting therefor.

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

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

7.  TENANT MAINTENANCE  Except as otherwise provided in Paragraphs 21, 51 and
53, Tenant shall, at its sole cost and expense, keep and maintain the Premises
(including appurtenances) and every part thereof in a high standard of
maintenance and repair, or replacement, and in good and sanitary condition.
Tenant's maintenance and repair responsibilities herein referred to include, but
are not limited to, janitorization, all windows (interior and exterior), window
frames, plate glass and glazing (destroyed by accident or act of third parties),
truck doors, plumbing systems (such as water and drain lines, sinks, toilets,
faucets, drains, showers and water fountains), electrical systems (such as
panels, conduits, outlets, lighting fixtures, lamps, bulbs, tubes and ballasts),
heating and airconditioning systems (such as compressors, fans, air handlers,
ducts, mixing boxes, thermostats, time clocks, boilers, heaters, supply and
return grills), and exterior surfaces of the building, store fronts, roofs,
downspouts, all interior improvements within the premises including but not
limited to wall coverings, window coverings, carpet, floor coverings,
partitioning, ceilings, doors (both interior and exterior), including closing
mechanisms, latches, locks, skylights (if any), automatic fire extinguishing
systems, and elevators and all other interior improvements of any nature
whatsoever, and all exterior improvements including but not limited to
landscaping, sidewalks, driveways, parking lots including striping and sealing,
sprinkler systems, lighting, ponds, fountains, waterways and drains. Tenant
hereby waives all rights under, and benefits of, Subsection 1 of Section 1932
and Section 1941 and 1942 of the California Civil Code and under any similar
law, statute or ordinance now or hereafter in effect. In the event any of the
above maintenance responsibilities apply to any other tenant(s) of Landlord
where there is common usage with other tenant(s), such maintenance
responsibilities and charges shall be allocated to the leased Premises by square
footage or other equitable basis as calculated and determined by Landlord.

8. UTILITIES  Tenant shall pay promptly, as the same become due, all charges for
water, gas, electricity, telephone, telex and other electronic communication
service, sewer service, waste pick-up and any other utilities, materials or
services furnished directly to or used by Tenant on or about the Premises during
the term of this Lease, including, without limitation, any temporary or
permanent utility surcharge or other exactions whether or not hereinafter
imposed. In the event the above charges apply to any other tenant(s) of Landlord
where there is common usage with  other tenant(s), such charges shall be
allocated to the leased Premises by square footage or other equitable basis as
calculated and determined by Landlord.

   Landlord shall not be liable for and Tenant shall not be entitled to any
abatement or reduction of rent by reason of any interruption or failure of
utility services to the Premises when such interruption or failure is caused by
accident, breakage, repair, strikes, lockouts, or other labor disturbances or
labor disputes of any nature, or by any other cause, similar or dissimilar,
beyond the reasonable control of Landlord.


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



                                  page 3 of 8
<PAGE>   4
reasonable attorneys' fees) incurred by Landlord in reasonably contesting any
Real Property Tax and in negotiating with public authorities as to any Real
Property Tax. If at any time during the term of this Lease the taxation or
assessment of the Premises prevailing as of the commencement date of this Lease
shall be altered so that in lieu 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 Premises or Landlord's interest therein or (ii)
on or measured by the gross receipts, income or rentals from the Premises, on
Landlord's business of leasing the Premises, or computed in any manner with
respect to the operation of the Premises, then any such tax or charge, however
designated, shall be included within the meaning of the term "Real Property
Taxes" for purposes of this Lease. If any Real Property Tax is based upon
property or rents unrelated to the Premises, then only that part of such Real
Property Tax that is fairly allocable to the Premises shall be included within
the meaning of the term "Real Property Taxes". Notwithstanding the foregoing,
the term "Real Property Taxes" shall not include estate, inheritance, gift or
franchise taxes of Landlord or the federal or state net income tax imposed on
Landlord's income from all sources.

     B. Taxes on Tenant's Property. Tenant shall be liable for and shall pay ten
days before delinquency, taxes levied against any personal property or trade
fixtures placed by Tenant in or about the Premises. If any such taxes on
Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property or 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 property protest if
requested by Tenant, Tenant shall upon demand, as the case may be, repay to
Landlord the taxes so levied against Landlord, or the proportion of such taxes
resulting from such increase in the assessment; provided that in any such event
Tenant shall have the right, in the name of Landlord and with Landlord's full
cooperation, to bring suit in any court of competent jurisdiction to recover the
amount of such taxes so paid under protest, and any amount so recovered shall
belong to Tenant.

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

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

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

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

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

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

14. COMPLIANCE  Tenant, all 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. Tenant shall, at its
sole cost and expense, comply with any and all requirements pertaining to said
Premises, of any insurance organization or company, necessary for the
maintenance of reasonable fire and public liability insurance covering
requirements pertaining to said Premises, of any insurance organization or
company, necessary for the maintenance of reasonable fire and public liability
insurance covering the Premises.

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

16. ASSIGNMENT AND SUBLETTING  Tenant shall not assign, transfer, or hypothecate
the leasehold estate under this Lease, or any interest therein, and shall not
sublet the Premises, or any part thereof, or any right or privilege appurtenant
thereto, or suffer any other person or entity to occupy or use the Premises, or
any portion thereof, without, in each case, the prior written consent of
Landlord which consent will not be unreasonably withheld. As a condition for
granting this consent to any assignment, transfer, or subletting, Landlord may
require that Tenant agrees to pay to Landlord, as additional rent, fifty percent
(50%) of all rents or additional consideration received by Tenant from its
assignees, transferees, or subtenants in excess of the rent payable by Tenant to
Landlord hereunder provided, however, that for sharing such excess rent, Tenant
shall be first entitled to recover from such excess rent the amount of all
reasonable leasing commissions paid to third parties not affiliated with Tenant
in order to obtain the assignment or sublease in question. Tenant shall, by
thirty (30) days written notice, advise Landlord of its intent to assign or
transfer Tenant's interest in the Lease or sublet the Premises or any portion
thereof for any part of 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

                                  page 4 of 8
<PAGE>   5
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 which consent shall not be unreasonably withheld. 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 which consent shall not be unreasonably
withheld. 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 transferees) to assume in writing
all of the obligations under this Lease and for Tenant to remain liable to
Landlord under the Lease.

See Paragraph 45

17.  SUBORDINATION AND MORTGAGES  In the event Landlord's title or leasehold
interest is now or hereafter encumbered by a deed of trust, upon the interest of
Landlord in the land and buildings in which the demised Premises are located, to
secure a loan from a lender (hereinafter referred to as "Lender") to Landlord,
Tenant shall, at the request of Landlord or Lender, execute in writing an
agreement subordinating its rights under this Lease to the lien of such deed of
trust, or, if so requested, agreeing that the lien of Lender's deed of trust
shall be or remain subject and subordinate to the rights of Tenant under this
Lease. 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 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. See Paragraph 46.

18.  ENTRY BY LANDLORD  Landlord reserves, and shall at all reasonable times
after at least 24 hours notice (except in emergencies) have, the right to enter
the Premises to inspect them; to perform any services to be provided by Landlord
hereunder; to make repairs or provide any services to a contiguous tenant(s); to
submit the Premises to prospective purchasers, mortgagers or tenants; to post
notices of nonresponsibility; and to alter, improve or repair the Premises or
other parts of the building, all without abatement of rent, and may erect
scaffolding and other necessary structures in or through the Premises where
reasonably required by the character of the work to be performed; provided,
however that the business of Tenant shall be interfered with to the least extent
that is reasonably practical. Any entry to the Premises by Landlord for the
purposes provided for herein shall not under any circumstances be construed or
deemed to be a forcible or unlawful entry into or a detainer of the Premises or
an eviction, actual or constructive, of Tenant from the Premises or any portion
thereof. See Paragraph 47

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

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

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

     The failure to perform or honor any covenant, condition or representation
made under this Lease shall constitute a default hereunder by Tenant upon
expiration of the appropriate grace period hereinafter provided. Tenant shall
have a period of five (5)days from the date of written notice from Landlord
within which to cure any default in the payment of rental or adjustment
thereto. Tenant shall have a period of thirty (30) days from the date of
written notice from Landlord within which to cure any other default under this
Lease; provided, however, that if the nature of Tenant's failure is such that
more than thirty (30) days in reasonably required to cure the same, Tenant
shall not be in default so long as Tenant commences performance with in such
thirty (30) day period and thereafter prosecutes the same to completion.
Upon an uncured default of this Lease by Tenant, Landlord shall have
the following rights and remedies in addition to any other rights or remedies
available to Landlord at law or in equity:

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

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

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

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

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

20.  ABANDONMENT  Tenant shall not vacate or abandon the Premises at any time
during the term of this Lease (except that Tenant may vacate so long as it pays
rent, provides an on-site security guard during normal business hours from
Monday through Friday, and otherwise performs its obligations hereunder), and if
Tenant shall abandon, vacate or surrender said premises, or be dispossessed by
the process of law, or otherwise, any personal property belonging to Tenant and
left on the Premises shall be deemed to be abandoned, at the option of Landlord
except such property as may be mortgaged to Landlord.

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



                                  page 5 of 8

<PAGE>   6
damage and destruction caused from vandalism and accidents for which Tenant is
responsible under Paragraph 7. Landlord shall elect to either:

            (a)   Rebuild or restore the Premises to their condition prior to
the damage or destruction, or

            (b)   Terminate this Lease. (providing that the Premises is damaged
to the extent of 33 1/3% or more of the replacement cost)

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

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

      In the event that the building in which the Premises are situated is
damaged or destroyed to the extent of not less than 33 1/3% of the replacement
cost thereof, Landlord may elect to terminate this Lease, whether the Premises
be injured or not.

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

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

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

23.   SALE OR CONVEYANCE BY LANDLORD In the event of a sale or conveyance of the
Premises or any interest therein, by any owner of the reversion then
constituting Landlord, the transferor shall thereby be released from any further
liability upon any of the terms, covenants or conditions (express or implied)
herein contained in favor of Tenant, and in such event, insofar as such transfer
is concerned, Tenant agrees to look solely to the responsibility of the
successor in interest of such transferor in and to the Premises and this Lease.
This Lease shall not be affected by any such sale or conveyance, and Tenant
agrees to attorn to the successor in interest of such transferor. See Paragraph
48.

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

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

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

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

28.   RIGHT OF LANDLORD TO PERFORM All terms, covenants and conditions of this
Lease to be performed or observed by Tenant shall 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 obliged
to, make any such payment or perform any such other term or covenant on Tenant's
part to be performed. All sums so paid by Landlord and all necessary costs of
such performance by Landlord together with interest thereon at the rate of the
prime rate of interest per annum as quoted by the Bank of America from the date
of such payment on performance by Landlord, shall be paid (and Tenant covenants
to make such payment) to Landlord on demand by Landlord, and Landlord shall have
(in addition to any other right or remedy of Landlord) the same rights and
remedies in the event of nonpayment by Tenant as in the case of failure by
Tenant in the payment of rent hereunder.

29.   ATTORNEYS' FEES

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

                                  page 6 of 8
<PAGE>   7

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

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

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

31. NOTICES All notices, demands, requests, advices or designations which may
be or are required to be given by either party to the other hereunder shall be
in writing. All notices, demands, requests, advices or designations by Landlord
to Tenant shall be sufficiently given, made or delivered if personally served
on Tenant by leaving the same at the Premises of if sent by United States
certified or registered mail, postage prepaid, addressed to Tenant at the
Premises. All notices, demands, requests, advices or designations by Tenant to
Landlord shall be sent by United States certified or registered mail, postage
prepaid, addressed to Landlord at its offices at A&P FAMILY INVESTMENTS, C/O
PEERY/ARRILLAGA, 2560 MISSION COLLEGE BLVD., SUITE 101, SANTA CLARA, CA 95054.
Each notice, request, demand, advice or designation referred to in this
paragraph shall be deemed received on the date of the personal service or
mailing thereof in the manner herein provided, as the case may be.

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

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

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

36. 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;

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

      (b)   no partner of Landlord shall be sued or named as a party in any

partnership);

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

set aside at any time without hearing;

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

      (h) these covenants and agreements are enforceable both by Landlord and

inscribed, displayed or 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

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.

42. CONSENT: Whenever the consent of one party to the other is required

43. HAZARDOUS MATERIALS: Landlord and Tenant agree as follows with respect to
the existence or use of "Hazardous Materials" (as defined herein) on, in, under
or about the Premises and real property located beneath said Premises
(hereinafter collectively referred to as the "Property").

As used herein, the term "Hazardous Materials" shall mean any hazardous or toxic
substance, material or waste which is or becomes subject to or regulated by any
local governmental authority, the State of California, or the United States
Government. The term "Hazardous Materials" includes, without limitation any

Except to the extent otherwise specifically stated in this Paragraph 43, Tenant
shall have no obligation to "clean up", reimburse, release, indemnify, or defend
Landlord with respect to the presence of Hazardous Materials on the Property.

Notwithstanding the immediately preceding subparagraph, and except to the extent
caused by Landlord, its agents, employees, or contractors, Tenant shall be 100%
liable and responsible for the following to the extent required by applicable
law: (i) any and all "clean up" of Hazardous Materials contamination resulting
from the use, storage, disposal, transportation, or release of Hazardous
Materials within the Premises during the term of the Lease (excluding
contamination resulting from subsurface migration of Hazardous Materials
originating from other property and not caused by or contributed to by Tenant),
and (ii) any and all "clean up" of Hazardous Materials contamination of any
portion of the Property (including the Premises) resulting from the use,
storage, disposal, transportation, or release of Hazardous Materials by Tenant,
its agents, employees, contractors, invitees or its future subtenants and/or
assignees or third parties on the Property. Tenant shall indemnify Landlord and
hold Landlord harmless from any claims, liabilities, demands, costs, expenses
and damages, including, without limitation, attorneys' fees, incurred as a
result of any claims resulting from any Hazardous Materials contamination
described in clauses (i) and (ii) of the immediately preceding sentence.

Tenant also agrees not to use or dispose of any Hazardous Materials on the
Property without first obtaining Landlord's written consent, provided, however,
that Tenant may use Hazardous Materials needed in the conduct of its business so
long as Tenant notifies Landlord in writing of such Hazardous Materials to be
brought upon the Premises and so long as Tenant strictly complies with all laws
regulating the use, storage, and disposal of such Hazardous Materials. Tenant
agrees to complete compliance with governmental regulating the use or removal or
remediation of Hazardous Materials stored, disposed, transported, or caused to
be on the Property as stated above, and prior to the termination of said Lease.
Tenant agrees to follow the proper closure procedures and will obtain a
clearance from the local fire department and/or the appropriate governing
agencies. If Tenant uses Hazardous Materials, Tenant also agrees to install, at
Tenant's expense, such Hazardous Materials monitoring devices as Landlord deems
reasonably necessary. It is agreed that the Tenant's responsibilities related to
Hazardous Materials will survive the termination date of the Lease and that
Landlord may obtain specific performance of Tenant's responsibilities under this
Paragraph 43.

Landlord hereby makes the following representations to Tenant, each of which is
made only to the best of Landlord's knowledge as of the date Landlord executes
this Lease, without any inquiry or investigation having been made or required by
Landlord regarding this subject, nor does Landlord have any obligation to
investigate or make inquiry regarding the subject:

        1) Landlord, to the best of its knowledge as of the date of this Lease,
has no knowledge of any environmental problems (including any release of
Hazardous Materials affecting the groundwater or soil on or under the Property
which violates any laws to the extent that any governmental entity could require
either Landlord or Tenant to take any remedial action with respect to such
Hazardous Materials) existing on the Property.

44. AMENDMENTS TO LEASE: Tenant agrees to execute any amendments reasonably
required by a lender to enable Landlord to obtain financing, so long as Tenant's
rights hereunder are not materially and adversely affected and there is no
change in Basic Rent, Additional Rent, any Options to Renew, or the Term of this
Lease.

45. ASSIGNMENT AND SUBLETTING (CONTINUED):

        A. Permitted Assignments and Subletting: In addition to and
notwithstanding anything to the contrary in Paragraph 16 of this Lease, Tenant
shall be entitled to assign or sublet without Landlord's consent (but shall
still give Landlord notice thereof, however, Landlord shall not be entitled to
terminate this Lease on account of such Permitted Assignment) to: (i) any parent
or subsidiary corporation, or corporation with which Tenant merges or
consolidates, or (ii) any third party or entity to whom Tenant sells all or
substantially all of its assets (collectively referred to as "Permitted
Assignment"); provided, that the net worth of the resulting or acquiring
corporation has a net worth after the merger, consolidation or acquisition equal
to or greater than the net worth of Tenant at the time of such merger,
consolidation or acquisition. No such assignment or subletting will release the
Tenant from its liability and responsibility under this Lease to the extent
Tenant continues in existence following such transaction. Landlord shall not be
entitled to share to the proceeds of any excess rent Tenant may receive from a
Permitted Assignment.

        B. Excess Rent: In addition to and notwithstanding anything to the
contrary in Paragraph 16, for the first thirty (30) months of the Lease Term,
Tenant shall be entitled to retain one hundred percent (100%) of any rent
received by Tenant from its assignees, transferees, or subtenants in excess of
the Rent payable by Tenant to Landlord under this Lease (the "Excess Rent");
thereafter and throughout the Term of the Lease, Tenant shall be entitled to
retain fifty percent (50%) of any Excess Rent; provided, however, that prior to
sharing such Excess Rent, Tenant shall be first entitled to recover from such
Excess Rent the amount of all reasonable leasing commissions paid to third
parties not affiliated with Tenant in order to obtain the assignment or sublease
in question; the net amount of the Excess Rent (after the deduction of the
aforementioned commission) shall then be shared equally between Landlord and
Tenant as noted above.

46. SUBORDINATION AND MORTGAGES (CONTINUED): Paragraph 17 is modified to provide
that this Lease shall not subordinate to a mortgage or deed of trust unless the
lender holding such mortgage or deed of trust enter into a written
subordination, non-disturbance and attornment agreement in which the lender
agrees that notwithstanding any subordination of this Lease to such lender's
mortgage or deed of trust, (i) such Lender shall recognize all of Tenants rights
under this Lease, and (ii) in the event of a foreclosure, this Lease shall not
be terminated so long as Tenant in not in material default of its obligations
under this Lease, but shall continue in effect and Tenant and such lender (or
any party acquiring the Premises through such foreclosure) shall each be bound
to perform in the respective obligations of Tenant and Landlord with respect to
the Premises arising after such foreclosure.

47. ENTRY BY LANDLORD (CONTINUED): Notwithstanding the provisions of Paragraph
18, (i) except in the event of an emergency, Landlord shall give Tenant
twenty-four (24) hours notice prior to entering the Premises, agrees to comply
with any reasonably safety and/or security regulations imposed by Tenant with
respect to such entry, and shall only enter the Premises when accompanied by
Tenant or its agent (so long as Tenant makes itself reasonably available for
this purpose), and (ii) Landlord may install "for lease" signs relating to the
Premises only during the last 180 days of the Lease term. Landlord agrees to use
its reasonable, good faith efforts such that any entry by Landlord, and
Landlord's agents, employees, contractors and invitees shall be performed in a
manner with as minimal interference as possible with Tenant's business at the
Premises. Subject to the foregoing, Tenant agrees to cooperate with Landlord and
Landlord's agents, employees and contractors so that responsibilities of
Landlord under the Lease can be fulfilled in a reasonable manner during normal
business hours so that no extraordinary costs are incurred by Landlord.

48. SALE OR CONVEYANCE BY LANDLORD (CONTINUED):

The provisions of Paragraph 23 of the Lease to the contrary notwithstanding,
upon any sale or transfer, (i) Landlord shall not be released from any then
outstanding liability arising under this Lease during the period preceding the
date of transfer, and (ii) Landlord shall not be relieved of the obligations
under the Lease which may accrue after the date of a sale or other transfer
unless the transferee agrees in writing to assume and be bound by the terms of
this Lease and to perform all obligations of the Landlord under the Lease which
may accrue after the date of such transfer.

49. LANDLORD'S LIEN WAIVER: Landlord, within thirty (30) days after demand from
Tenant, shall execute and deliver Landlord's Lien Waiver as reasonably required
by any supplier, lessor, or lender in connection with the installation in the
Premises of the Tenants personal property or trade fixtures.

50. ALTERATIONS MADE BY TENANT: The provisions of this Paragraph 50 shall modify
Paragraphs 8 and 9 of the Lease, as follows:

        A. Tenant shall have the right to reconfigure modular,
non-floor-to-ceiling walls and non-floor-to-ceiling partitions without
Landlord's prior consent, which have been installed by Tenant and paid for by
Tenant.

      B. At all times during the Lease Term, (i) Tenant shall maintain and keep
updated "as built" plans for all alterations constructed by Tenant, and (ii)
Tenant shall provide to Landlord copies of such "as built" plans as such
alterations (which alterations are subject to Landlord's prior written consent)
are made.

        C. At all times during the Term of this Lease, Tenant shall have the
right to install and remove trade fixtures as defined in the Lease which are
installed and paid for by Tenant, so long as Tenant immediately repairs all
damage caused by the installation thereof and returns the Premises to the
condition existing prior to the installation of such trade fixtures and repairs
and restores any so-called "donuts" or gaps in the roof and/or floor (including
floor structure, subfloor and appropriate floor covering for said area) and/or
floor tiles and/or ceiling tiles and lighting resulting from the removal of said
trade fixtures.

51. MAINTENANCE OF THE PREMISES: In addition to, and notwithstanding anything to
the contrary in Paragraph 7, Landlord shall maintain the structural shell,
foundation, and roof structure (but not the interior improvements, roof
membrane, or glazing) of the building leased hereunder at Landlord's cost and
expense, provided Tenant has not caused such damage, in which event Tenant shall
be responsible for 100 percent of any such costs for repair or damage so caused
by the Tenant. Notwithstanding the foregoing, a crack in the foundation, or
exterior walls that does not endanger the structural integrity of the building,
or which is not life-threatening, shall not be considered material, nor shall
Landlord be responsible for repair of same.

52. SIGNS (CONTINUED): Notwithstanding anything contained in Paragraph 37,
Tenant may, at its expense, install its name of the glass portion of the
building, provided Tenant obtains and complies with the required permit of the
City of Santa Clara and further provided Tenant removes the same by Lease
Termination and repairs any and all damage to the glass surface of the building.

53. REPLACEMENT OF HVAC AND/OR ROOF MEMBRANE: Notwithstanding anything to the
contrary herein, Landlord agrees, at its cost and expense, to have the roof
membrane replaced during the first eighteen (18) months of the Lease Term, and
Tenant shall not be responsible for any portion of the cost of the initial
replacement of the roof membrane unless Tenant causes damage to the same in
which event Tenant shall be responsible for one hundred percent (100%) of the
cost of replacement related to the area(s) damaged by Tenant.

In the event Landlord reasonably deems it necessary to replace an HVAC unit
(provided said replacement is not the result of damage caused by Tenant, its
agents, employees, invitees, contractors, or its future subtenants and/or
assignees (if any)) to the Leased Premises during the Term of the Lease,
Landlord shall have said HVAC unit replaced and Landlord shall amortize the cost
of the replacement over the useful life of said replacement in accordance with
standard accounting practices, and Tenant shall be responsible for paying to
Landlord one hundred percent (100%) of Tenant's pro rata share of the
amortization of said cost of said replacement over the term remaining in the
Lease at the time the replacement is made. For Example: In the event: (i) the
HVAC unit is replaced at a cost of $50,000; and (ii) said HVAC unit has a useful
life of ten years; and (iii) Tenant has one year remaining in its Lease Term at
the time said replacement is made, Tenant would be charged $5,000 as Additional
Rent, in which case the $5,000 would be due within thirty (30) days of notice
from Landlord. Tenant hereby waives all rights under, and benefits of subsection
I of Section 1932 and Sections 1941 and 1942 of the California Civil Code and
under any similar law, statute or ordinance now or hereafter in effect.

In the event the Term of the Lease is extended by any agreement between Landlord
and Tenant, Tenant's pro rata share of the earlier replacement cost shall be
increased to include the additional amount payable to Landlord due to the
Extended Term of the Lease. For Example:


                                     Page 12               Initial: /s/
                                                                    ------------

<PAGE>   13

In the event: (i) the HVAC unit was replaced as illustrated above, and (ii)
Tenant extends this Lease for an additional five year period, Tenant would be
liable for an additional payment to Landlord of $25,000 as Additional Rent. Said
payment would be due in full immediately upon execution of an agreement to
extend the Lease Term.

54. CONSTRUCTION OF TENANT IMPROVEMENTS RELATED TO LABORATORY AREA AND
AMORTIZATION OF SAID COSTS: It is hereby understood and agreed between the
parties that Landlord shall construct a laboratory (the "Lab Improvements") in
the Leased Premises shown on Exhibit B to be attached hereto at Tenant's sole
cost and expense.

        A. Costs and Construction of Lab Improvements: Tenant shall provide
Landlord with a 1/8" scale drawing of the Lab Improvements and specifications
thereto which Landlord is to construct on Tenant's behalf (said plans shall
become Exhibit C to the Lease); Landlord shall obtain bids for the construction
of the Lab Improvements and Landlord shall provide Tenant with the cost to
construct (including labor, materials and permit fees ("Lab Costs")). Tenant
shall not be allowed to make changes to the Lab Improvements design or materials
used therein after it submits its Lab Improvements plans to Landlord. Tenant
shall: (i) approve the Lab Costs in writing within three (3) business days after
Landlord presents the same to Tenant; or (ii) request Landlord to obtain
additional bids in which case any delay in the completion of the Lab
Improvements resulting from the rebidding process shall not delay the
Commencement Date of the Lease and said Lease shall commence on the date it
would have commenced absent the delay caused from the rebidding process. Failure
of Tenant to approve or disapprove the aforementioned Lab Costs within the three
(3) business day period shall be deemed approval by Tenant and Landlord shall
proceed with the construction of the improvements as though Landlord had
received Tenant's written approval as outlined above. It is further agreed, that
in the event any of the specifications for the Lab Improvements are specialized
materials that are not readily available and cause a delay in the completion of
the construction, this Lease shall commence on the date it otherwise would have
commenced absent the delay in the receipt of the specialized materials.

It is agreed by the parties hereto that: (i) in the event the Lab Improvements
constructed by Landlord do not conform exactly to the plans and specifications
as set forth on Exhibit; and (ii) provided the general appearance and Tenant's
use of the Lab Improvements are not materially or unreasonably affected by such
deviation, the Commencement Date of the Lease, and Tenant's obligation to pay
Rental, shall not be affected and Tenant hereby agrees, in such event, to accept
the Lab Improvements as constructed by Landlord.

        B. Amortization of Lab Improvements Costs: The Lab Costs shall be
amortized, without interest, over a nine (9) month period commencing August 1,
1995 through April 1, 1996. Said amortization will result in Tenant's Basic Rent
Schedule and Aggregate Rent being amended. Therefore, the revised monthly Basic
Rental rate during said nine (9) month period will be based on the Basic Rental
rate, as provided for in Paragraph 39, plus the amortized principal. For
example, if the Construction Costs are $30,000.00, the Basic Rent Schedule shall
be amended as follows:

                                 LEASE AGREEMENT

The Basic Lease Information set forth on Page 1 and this Lease are and shall be
construed as a single instrument.

1.      PREMISES

Landlord hereby leases the Premises to Tenant upon the terms and conditions
contained herein. Tenant shall have the right to use, on a non-exclusive basis,
parking areas (including the parking spaces) and ancillary facilities located
within the Common Areas of the Park, subject to the terms of this Lease.
Landlord and Tenant hereby agree that for purposes of this Lease, as of the
Lease Date, the rentable square footage area of each of the Premises, the
Building, the Phase (if any) and the Park shall be deemed to be the number of
rentable square feet as set forth in the Basic Lease Information. Tenant hereby
acknowledges that the rentable square footage of the Premises may include a
proportionate share of certain areas used in common by all occupants of the
Building, the Phase (if any) and/or the Park (for example corridors, common
restrooms, an electrical room or telephone room). Tenant further agrees that the
number of rentable square feet of any of the Building, the Phase (if any) and
the Park may subsequently change after the Lease Date commensurate with any
modifications to any of the foregoing by Landlord, and Tenant's Share shall
accordingly change. The term "Project" as used herein shall mean and
collectively refer to the Building, the Common Areas, the Lot, the Phase (if
any) and the Park in the condition described in Section 5 hereof.

2.      OCCUPANCY; ADJUSTMENT OF COMMENCEMENT DATE

        2.1 If Landlord, for any reason whatsoever, cannot deliver possession of
the Premises to Tenant on the Commencement Date in the condition specified in
Section 5 hereof, Landlord shall not be subject to any liability nor shall the
validity of the Lease be affected; provided, the Term of this Lease and the
obligation to pay Rent shall commence on the date possession of the Premises is
actually tendered to Tenant in the condition described in Section 5 and the Work
Letter, and the Expiration Date shall be extended commensurately. If the
commencement date and/or the expiration date of this Lease is other than the
Commencement Date and Expiration Date specified in the Basic Lease Information,
Landlord and Tenant shall execute a written amendment to this Lease,
substantially in the form of Exhibit F hereto, wherein the parties shall specify
the actual commencement date, expiration date and the date on which Tenant is to
commence paying Rent. The word "Term" whenever used herein refers to the initial
term of this Lease and any valid extension(s) thereof. Notwithstanding the
above, if the Premises are not delivered to Tenant in a substantially complete
condition subject to Tenant Delays and Force Majeure Delays as defined in
Exhibit B herein, on or before January 1, 2001, then Tenant may terminate this
Lease upon providing ten (10) days' prior written notice to Landlord on or
before January 10, 2001, in which case the Advance Rent, Security Deposit,
Letter of Credit and other prepaid amounts shall be returned to Tenant.

        2.2 If Landlord permits Tenant to occupy the Premises prior to the
actual Commencement Date, such occupancy shall be at Tenant's sole risk and
subject to all the provisions of this Lease. Additionally, Landlord shall have
the right to impose additional reasonable conditions on Tenant's early
occupancy.

3.      RENT

On the date that Tenant executes this Lease, Tenant shall deliver to Landlord
the original executed Lease, the Advance Rent (which shall be applied against
the Rent payable for the first month(s) Tenant is required to pay Rent), the
Security Deposit, and all insurance certificates evidencing the insurance
required to be Obtained by Tenant under Section 12 and Exhibit of this Lease.
Tenant agrees to pay Landlord the Base Rent, without prior notice or demand,
abatement, offset, deduction or claim except as expressly otherwise set forth
herein, in advance at Landlord's Address on the Commencement Date and thereafter
on the first (1st) day of each month throughout the balance of the Term of the
Lease. In addition to the Base Rent, Tenant shall pay Landlord in advance on the
Commencement Date and thereafter on the first (1st) day of each month throughout
the balance of the Term of this Lease, as Additional Rent, Tenants Share of
Operating Expenses, Tax Expenses, Common Area Utility Costs, and Utility
Expenses. The term "Rent" whenever used herein refers to the aggregate of all
these amounts. If Landlord permits Tenant to occupy the Premises without
requiring Tenant to pay rental payments for a period of time, the waiver of the
requirement to pay rental payments shall only apply to the waiver of the Base
Rent. The Rent for any fractional part of a calendar month at the commencement
or expiration or termination of the Lease Term shall be a prorated amount of the
Rent for a full calendar month based upon a thirty (30) day month. To the extent
not already paid as part of the Advance Rent any prorated Rent shall be paid on
the Commencement Date, and any prorated Rent for the final calendar month hereof
shall be paid on the first day of the calendar month in which the date of
expiration or termination occurs.

4.      SECURITY DEPOSIT

Simultaneously with Tenant's execution and delivery of this Lease, Tenant shall
deliver to Landlord, as a Security Deposit for the faithful performance by
Tenant of its obligations under this Lease, the amount specified in the Basic
Lease Information. If Tenant is in default hereunder beyond any applicable
notice and cure period, Landlord may, but without obligation to do so, use all
or any portion of the Security Deposit to cure the default or to compensate
Landlord for all damages sustained by Landlord in connection therewith. Tenant
shall, immediately on demand, pay to Landlord a sum equal to the portion of the
Security Deposit so applied or used to replenish the amount of the Security
Deposit held to increase such deposit to the amount initially deposited with
Landlord. At any time after Tenant has defaulted hereunder, Landlord may require
an increase in the amount of the Security Deposit required hereunder for the
then balance of the Term and Tenant shall, immediately on demand, pay to
Landlord such additional sums. As soon as practicable after the expiration or
termination of this Lease but in no event later than sixty (60) days thereafter,
Landlord shall return the Security Deposit to Tenant, less such amounts as are
reasonably necessary, as determined by Landlord, to remedy Tenant's default(s)
hereunder or to otherwise restore the Premises to a clean and safe condition,
reasonable wear and tear excepted, casualty and condemnation and damage caused
by the gross negligence or willful misconduct of Landlord or Landlord's
Representatives excepted. If the cost to restore the Premises exceeds the amount
of the Security Deposit, Tenant shall promptly deliver to Landlord any and all
of such excess sums. Landlord shall not be required to keep the Security Deposit
separate from other funds, and, unless otherwise required by law, Tenant shall
not be entitled to interest on the Security Deposit. In no event or circumstance
shall Tenant have the right to any use of the Security Deposit and,
specifically, Tenant may not use the Security Deposit as a credit or to
otherwise offset any payments required hereunder.

thirty (30) days of Landlord's delivery of such accounting, Tenant shall pay to
Landlord the amount of any underpayment. Notwithstanding the foregoing, failure
by Landlord to give such accounting by such date shall not constitute a waiver
by Landlord of its right to collect any underpayment by Tenant at any time.
Landlord shall credit the amount of any overpayment by Tenant toward the next
estimated monthly installment(s) falling due, or where the Term of the Lease has
expired, refund the amount of overpayment to Tenant as soon as possible
thereafter. If the Term of the Lease expires prior to the annual reconciliation
of expenses Landlord shall have the right to reasonably estimate Tenant's Share
of such expenses, and if Landlord determines that there has been an
underpayment, Landlord may deduct such underpayment from Tenant's Security
Deposit. Failure by Landlord to accurately estimate Tenant's Share of such
expenses or to otherwise perform such reconciliation of expenses shall not
constitute a waiver of Landlord's right to collect any of Tenant's underpayment
at any time during the Term of the Lease or at any time after the expiration or
earlier termination of this Lease.

        6.5 AUDIT: After delivery to Landlord of at least thirty (30) days prior
written notice, Tenant, at its sole cost and expense through any accountant
designated by it, shall have the right to examine and/or audit the books and
records evidencing such costs and expenses for the previous one (1) calendar
year, during Landlord's reasonable business hours but not more frequently than
once during any calendar year. Any such accounting firm designated by Tenant may
not be compensated on a contingency fee basis. The results of any such audit
(and any negotiations between the parties related thereto) shall be maintained
strictly confidential by Tenant and its accounting firm and shall not be
disclosed, published or otherwise disseminated to any other party other than to
Landlord and its authorized agents. Landlord and Tenant each shall use its best
efforts to cooperate in such negotiations and to promptly resolve any
discrepancies between Landlord and Tenant in the accounting of such costs and
expenses if through such audit it is determined that there is a discrepancy of
more than seven percent (7%) of the actual Operating Expenses and Tax Expenses
for such period, then Landlord shall reimburse Tenant for the reasonable
accounting costs and expenses incurred by Tenant in performing such audit,
including Tenant's in-house or outside auditors or accountants. However, if
through such audit it is determined that there is a discrepancy of seven percent
(7%) or less, then Tenant shall reimburse Landlord for the reasonable accounting
costs and expenses associated with Landlord's in-house auditors or accounting
personnel as well as those reasonable costs and expenses incurred by Landlord
for any outside accounting firms or auditors in connection with such audit.

7.      UTILITIES AND SERVICES

Tenant shall pay the cost of all (i) water, sewer use, sewer discharge fees and
sewer connection fees, gas, electricity, telephone, telecommunications, cabling
and other utilities billed or metered separately to the Premises and (ii) refuse
pickup and janitorial service to the Premises. Utility Expenses, Common Area
Utility Costs and all other sums and charges set forth in this Section 7 are
considered part of Additional Rent.

        7.1 UTILITY EXPENSES: For any such utility fees, use charges, or similar
services that are not billed or metered separately to Tenant, including without
limitation, water and sewer charges, and garbage and waste disposal
(collectively, "Utility Expenses"), Tenant shall pay to Landlord Tenant's Share
of Utility Expenses. If Landlord reasonably determines that Tenant's Share of
Utility Expenses is not commensurate with Tenant's use of such services, Tenant
shall pay to Landlord the amount which is attributable to Tenant's use of the
utilities or similar services, as reasonably estimated and determined by
Landlord, based upon factors such as size of the Premises and intensity of use
of such utilities by Tenant such that Tenant shall pay the portion of such
charges reasonably consistent with Tenant's use of such utilities and similar
services. Tenant shall also pay Tenant's Share of any assessments, charges, and
fees included within any tax bill for the Lot on which the Premises are
situated, including without limitation, entitlement fees, allocation unit fees,
sewer use fees, and any other similar fees or charges.

        7.2 COMMON AREA UTILITY COSTS: Tenant shall pay to Landlord Tenant's
Share of any Common Area utility costs, fees, charges and expenses
(collectively, "Common Area Utility Costs"). Tenant shall pay to Landlord
one-twelfth (1/12th) of the estimated amount of Tenant's Share of the Common
Area Utility Costs on the Commencement Date and thereafter on the first (1st)
day of each month throughout the balance of the Term of this Lease. Any
reconciliation thereof shall be substantially in the same manner as set forth in
Section 6.4 above.

        7.3 MISCELLANEOUS: Tenant acknowledges that the Premises may become
subject to the rationing of utility services or restrictions on utility use as
required by a public utility company, governmental agency or other similar
entity having jurisdiction thereof. Tenant agrees that its tenancy and occupancy
hereunder shall be subject to such rationing restrictions as may be imposed upon
Landlord, Tenant, the Premises, or other portions of the Project, and Tenant
shall in no event be excused or relieved from any covenant or obligation to be
kept or performed by Tenant by reason of any such rationing or restrictions. If
permitted by applicable Laws, Landlord shall have the right at any time and from
time to time during the Term of this Lease to either contract for service from a
different company or companies (each such company referred to as an "Alternate
Service Provider") other than the company or companies presently providing
electricity service for the Project (the "Electric Service Provider") or
continue to contract for service from the Electric Service Provider, at
Landlord's sole discretion. Tenant agrees to cooperate with Landlord, the
Electric Service Provider, and any Alternate Service Provider at all times and,
as reasonably necessary, shall allow Landlord, the Electric Service Provider,
and any Alternate Service Provider reasonable access to the Building's electric
lines, feeders, risers, wiring, and any other machinery within the Premises.

8.      LATE CHARGES

Any and all sums or charges set forth in this Section 8 are considered part of
Additional Rent. Tenant acknowledges that late payment (the fifth day of each
month or any time thereafter) by Tenant to Landlord of Rent and all other sums
due hereunder, will cause Landlord to incur costs not contemplated by this
Lease. Such costs may include, without limitation, processing and accounting
charges, and late charges that may be imposed on Landlord by the terms of any
note secured by any encumbrance against the Premises, and late charges and
penalties due to the late payment of Tax Expenses on the Premises. Therefore, if
any installment of Rent or any other sum payable by Tenant is not received by
Landlord within five (5) days of when due, Tenant shall promptly pay to Landlord
a late charge, as liquidated damages, in an amount equal to six percent (6%) of
such delinquent amount. Notwithstanding the foregoing, Landlord waives the late
charge for the first (1st) instance during each 12-month period during the Term
of this Lease in which Tenant fails to timely pay Rent. If Tenant delivers to
Landlord a check for which there are not sufficient funds, Landlord may require
Tenant to replace such check with a cashier's check for the amount of such check
and all other charges payable hereunder. The parties agree that this late charge
and the other charges referenced above represent a fair and reasonable estimate
of the costs that Landlord will incur by reason of such late payment by Tenant,
excluding attorneys' fees and costs. Acceptance of any late charge or other
charges shall not constitute a waiver by Landlord of Tenant's default with
respect to the delinquent amount, nor prevent Landlord from exercising any of
the other rights and remedies available to Landlord for any other breach of
Tenant under this Lease. If a late charge becomes payable for three (3)
installments of Rent, then Landlord, at Landlord's sole option, can either
require the Rent be paid quarterly in advance or be paid monthly in advance by
cashier's check or by electronic funds transfer.

9.      USE OF PREMISES

        9.1 COMPLIANCE WITH LAWS, RECORDED MATTERS, AND RULES AND REGULATIONS:
The Premises are to be used solely for the purposes and uses specified in the
Basic Lease Information and for no other uses or purposes without Landlord's
prior written consent. Landlord's consent shall not be unreasonably withheld or
delayed so long as the proposed use (i) does not involve the use of Hazardous
Materials other than as expressly permitted under the provisions of Section 29
below, (ii) does not require any additional parking spaces, and (iii) is
compatible with the other uses then being made in the Project and in other
similar types of buildings in the vicinity of the Project, as reasonably
determined by Landlord. The use of the Premises by Tenant and its employees,
representatives, agents, invitees, licensees, subtenants, customers or
contractors (collectively, "Tenant's Representatives") shall be subject to, and
at all times in compliance with, (a) any and all applicable laws, rules, codes,
ordinances, statutes, orders and regulations as same exist from time to time
throughout the Term of this Lease (collectively, the "Laws"), including without
limitation, the requirements of the Americans with Disabilities Act, a federal
law codified at 42 U.S.C. 12101 et seq., including but not limited to Title III
thereof, all regulations and guidelines related thereto and all requirements of
Title 24 of the State of California (collectively, the "ADA"), (b) any and all
documents, instruments, licenses, restrictions, easements or similar
instruments, conveyances or encumbrances which are at any time, and from time to
time, required to be made by or given by Landlord in any manner relating to the
initial development of the Project, and/or the construction from time to time of
any additional buildings or other improvements in the Project, including without
limitation any Tenant Improvements (collectively, the "Development Documents"),
(c) any and all documents, easements, covenants, conditions and restrictions,
and similar instruments, together with any and all amendments and supplements
thereto made from time to time each of which has been or hereafter is recorded

hereafter enacted relating to parking and the operation of the Premises and/or
any other part of the Project and any and all rules, restrictions and/or
regulations imposed by any applicable owners association or similar entity or
body (collectively, the "Rules and Regulations") provided that in the event of
any conflict between the terms of such rules and regulations and the terms of
the Lease, the terms of the Lease shall prevail. Landlord reserves to itself the
right, from time to time, to grant, without the consent of Tenant, such
easements, rights and dedications that Landlord deems reasonably necessary, and
to cause the recordation of parcel or subdivision maps and/or restrictions, so
long as such easements, rights, dedications, maps and restrictions, as
applicable, do not materially and adversely interfere with Tenant's operations
in and access to the Premises. Tenant agrees to sign any documents reasonably
requested by Landlord to effectuate any such easements, rights, dedications,
maps or restrictions, without expense or liability to Tenant. Tenant shall be
solely responsible for the payment of all costs, fees and expenses associated
with any modifications, improvements or other Alterations to the Premises and/or
any other portion of the Project occasioned by the enactment of, or changes to,
any Laws arising from Tenant's particular use of the Premises or Alterations or
other improvements made to the Premises by Tenant after the Commencement Date of
this Lease, regardless of when such Laws became effective, subject to any
violations existing as of the Commencement Date, Landlord's repair obligations
as set forth in Section 11.3 hereof and Landlord's obligations as set forth in
Exhibit B hereto, and latent defects in the original construction of the
Premises or systems serving the Premises which exist as of the Commencement
Date. Tenant shall not initiate, submit an application for, or otherwise
request, any land use approvals or entitlements with respect to the Premises or
any other portion of the Project, including without limitation, any variance,
conditional use permit or rezoning, without first obtaining Landlord's prior
written consent thereto, which consent may be given or withheld in Landlord's
sole discretion. Tenant shall not be responsible for any modifications,
improvements or alterations to the Premises, Building, the Common Areas and/or
the Park occasioned by the enactment of, or changes to, any Laws applicable to
all tenants in the Building and/or the Park generally, except to the extent that
costs and expenses incurred by Landlord with respect to such modifications,
improvements or alterations may be included as Operating Expenses as permitted
under Section 6.1. Tenant shall not be required to make any structural
modifications, improvements or alterations to the Premises, Building, Common
Areas or the Park, unless such structural work is required by reason of Tenant's
particular use and/or Tenant's modifications, improvements or alterations to the
Premises. Subject to Landlord's reasonable security measures, Tenant shall have
access to the Building and the Premises for its employees and visitors 24 hours
per day, 7 days per week.

        9.2 PROHIBITION ON USE: Tenant shall not use the Premises or permit
anything to be done in or about the Premises nor keep or bring anything therein
which will in any way increase the existing rate of or affect any policy of fire
or other insurance upon the Building or any of its contents, or cause a
cancellation of any insurance policy. No auctions (other than by electronic
media) may be held or otherwise conducted in, on or about any portion of the
Premises or the Project without Landlord's prior written consent thereto. Tenant
shall not do or permit anything to be done in or about the Premises which will
in any way obstruct or interfere with the rights of Landlord or other tenants or
occupants of any portion of the Project. The Premises shall not be used for any
unlawful purpose. Tenant shall not cause, maintain or permit any private or
public nuisance in, on or about any portion of the Premises or the Project,
including, but not limited to, any offensive odors, noises, fumes or vibrations.
Tenant shall not damage or deface or otherwise commit any waste in, upon or
about the Premises or any other portion of the Project. Tenant shall not place
or store, nor permit any other person or entity to place or store, any property,
equipment, materials, supplies, personal property or any other items or goods
outside of the Premises for any period of time, except (i) goods being staged
temporarily in connection with a move into or out of the Premises, (ii) tables,
chairs and benches for the use of Tenant's employees, and (iii) an emergency
generator with ancillary compressor and above ground diesel tank and equipment
associated with Tenant's light manufacturing, (subject to the Limitations set
forth in Section 27.3 below), all of the foregoing being subject to the
commercially reasonable prior written review and approval, conditions and
requirements of Landlord. Tenant shall not permit any animals, including, but
not limited to, any household pets, to be brought or kept in or about the
Premises. Tenant shall not install any radio or television antenna, satellite
dish, microwave, loudspeaker or other device on the roof or exterior walls of
the Building or any other portion of the Project, without first obtaining
Landlord's written consent, which consent shall not be unreasonably withheld or
delayed. Tenant shall not interfere with radio, telecommunication, or television
broadcasting or reception from or in the Building or elsewhere. Tenant shall
place no loads upon the floors, walls, or ceilings in excess of the maximum
designed load permitted by the applicable Uniform Building Code or which may
damage the Building or outside areas within the Project. Tenant shall not place
any harmful liquids in the drainage systems or dump or store waste materials,
refuse or other such materials, or allow such materials to remain outside the
Building area, except for any non-hazardous or non-harmful materials which may
be stored in refuse dumpsters.

10.     ALTERATIONS; AND SURRENDER OF PREMISES

        10.1 ALTERATIONS: Tenant shall not install any signs, fixtures,
improvements, nor make or permit any other alterations or additions
(individually, an "Alteration", and collectively, the "Alterations") to the
Premises without the prior written consent of Landlord, which consent shall not
be unreasonably withheld or delayed. However, Tenant shall be permitted to hang
pictures and shelving and perform other similar minor decorating activities and
to perform nonstructural alterations not exceeding an aggregate of $25,000
during any calendar year without securing Landlord's prior consent ("Permitted
Improvements"), provided that Tenant (i) complies with all pertinent building
codes and fire, safety and other such governmental regulations, (ii) does not
take any action which could in any way impact the structural, mechanical,
electrical, maintenance, HVAC or plumbing systems of the Premises and/or
exterior appearance of the Building and (iii) submits its plans for such
Alterations to Landlord at least fifteen (15) business days prior to
commencement of such Alterations (except as to minor decorative items and
installations of furniture for which plans are not required). Within ten (10)
business days following Landlord's receipt of Tenant's written notice with
respect to Tenant's performance of any Permitted Improvements and at such time
as Landlord may approve other Alterations, Landlord shall notify Tenant, in
writing, whether or not Landlord will require Tenant to remove such Permitted
Improvements and Alterations from the Premises upon the expiration or earlier
termination of this Lease. If any such Alteration is expressly permitted by
Landlord, Tenant shall deliver at least ten (10) days prior notice to Landlord,
from the date Tenant intends to commence construction, sufficient to enable
Landlord to post a Notice of Non-Responsibility. In all events, Tenant shall
obtain all permits or other governmental approvals prior to commencing any of
such work and deliver a copy of same to Landlord. All Alterations shall be at
Tenant's sole cost and expense, and shall be installed by a licensed contractor
(reasonably approved by Landlord) in compliance with all applicable Laws
(including, but not limited to, the ADA), Development Documents, Recorded
Matters, and Rules and Regulations. Tenant shall keep the Premises and the
property on which the Premises are situated free from any (liens arising out of
any work performed, materials furnished or obligations incurred by or on behalf

required by Landlord, and Tenant shall provide such assurances to Landlord,

        10.2 SURRENDER OF PREMISES: At the expiration of the Term or earlier
termination of this Lease, Tenant shall surrender the Premises to Landlord (a)
in good condition and repair (damage by acts of God, casualty, condemnation,
Landlord's gross negligence or willful misconduct and normal wear and tear
excepted), but with all interior walls cleaned, any carpets cleaned, all floors
cleaned and waxed, all non-working light bulbs and ballasts replaced and all
roll-up doors and plumbing fixtures in good condition and working order, and (b)
In accordance with the provisions of Section 27 hereof. Normal wear and tear
shall not include any damage or deterioration that would have been prevented by
proper maintenance by Tenant, or Tenant otherwise performing all of its
obligations under this Lease. On or before the expiration or earlier termination
of this Lease, (i) Tenant shall remove all of Tenant's Property (as hereinafter
defined) and Tenant's signage from the Premises and the other portions of the
Project, (ii) Landlord may, by written notice to Tenant given not later than one
hundred twenty (120) days prior to the Expiration Date (except in the event of a
termination of this Lease prior to the scheduled Expiration Date, in which event
no advance notice shall be required), require Tenant, at Tenant's expense, to
remove any or all Alterations and Tenant shall remove such requested Alterations
from the Premises, and (iii) to the extent Landlord has advised Tenant on or
about the time that the Tenant Improvements were constructed and installed in
the Premises that Tenant is to remove all or portions of the items comprising
the Tenant Improvements (the "Removable TIs"), Tenant shall remove the Removable
TIs. Tenant shall repair any damage caused by such removal of the Tenant's
Property, the requested Alterations and the Removable TIs. For purposes hereof,
the term "Tenant's Property" shall mean and refer to all equipment, trade
fixtures, computer wiring and cabling, furnishings, inventories, goods and
personal property of Tenant. Any of Tenant's Property not so removed by Tenant
as required herein shall be deemed abandoned and may be stored, removed, and
disposed of by Landlord at Tenant's expense, and Tenant waives all claims
against Landlord for any damages resulting from Landlord's retention and
disposition of such property; provided, however, Tenant shall remain liable to
Landlord for all costs incurred in storing and disposing of such abandoned
property of Tenant. All Tenant Improvements and Alterations except those which
Landlord requires Tenant to remove shall remain in the Premises as the property
of Landlord. If the Premises are not surrendered at the expiration of the Term
or earlier termination of this Lease, and in accordance with the provisions of
this Section 10 and Section 27 below, Tenant shall continue to be responsible
for the payment of Rent (as the same may be increased pursuant to Section 20
below) until the Premises are so surrendered in accordance with said provisions.
Tenant shall indemnify, defend and hold the Indemnitees (hereafter defined)
harmless from and against any and all damages, expenses, costs, losses or
liabilities arising from any delay by Tenant in so surrendering the Premises
including, without limitation, any damages, expenses, costs, losses or
liabilities arising from any claim against Landlord made by any succeeding
tenant or prospective tenant founded on or resulting from such delay and losses
and damages suffered by Landlord due to lost opportunities to lease any portion
of the Premises to any such succeeding tenant or prospective tenant, together
with, in each case, actual attorneys' fees and costs.

11. REPAIRS AND MAINTENANCE

        11.1 TENANT'S REPAIRS AND MAINTENANCE OBLIGATIONS: Except for those
portions of the Building to be maintained by Landlord, as provided in Sections
11.2 and 11.3 below, Tenant shall, at its sole cost and expense, keep and
maintain all parts of the Premises and such portions of the Building and
Improvements as are within the exclusive control of Tenant in good, clean and
safe condition and repair, promptly making all necessary repairs and

under warranties of Landlord's contractor, or (iii) repairs performed by
Landlord and charged to Tenant as Operating Expenses.

        11.2 MAINTENANCE BY LANDLORD: Subject to the provisions of Section 11.1,
and further subject to Tenant's obligation under Section 6 to reimburse
Landlord, in the form of Additional Rent, for Tenant's Share of the cost and
expense of the following described items, Landlord agrees to repair and maintain
the following items: fire protection services; the roof and roof coverings

electrical systems exclusively serving the Premises; any rail spur and rail

Project caused by or created due to any act, omission, negligence or willful
misconduct of Tenant or any of Tenant Representatives and to restore the

condition existing prior to the occurrence of such damage. If Landlord elects to
perform such repair and restoration work, Tenant shall reimburse Landlord upon
demand for all costs and expenses incurred by Landlord in connection therewith.
Tenant shall promptly report, in writing, to Landlord any defective condition
known to it which Landlord is required to repair, and failure to so report any
such defect shall make Tenant responsible to Landlord for any liability incurred
by Landlord by reason of such condition.

        11.3 LANDLORD'S REPAIRS AND MAINTENANCE OBLIGATIONS: Subject to the
provisions of Sections 11.1, 25 and 26, and except for repairs rendered
necessary by the intentional or negligent acts or omissions of Tenant or any of
Tenant's Representatives, unless such costs thereof are covered by insurance
requirement to be maintained herein, Landlord agrees, at Landlord's sole cost
and expense, to (a) keep in good repair the structural portions of the floors,
foundations and exterior perimeter walls of the Building (exclusive of glass and
exterior doors), below-ground plumbing and sewage facilities, and load-bearing
columns, and (b) replace the structural portions of the roof of the Building
(excluding the roof membrane).

<PAGE>   22

        11.4 TENANT'S FAILURE TO PERFORM REPAIRS AND MAINTENANCE OBLIGATIONS: If
Tenant refuses or neglects to repair and maintain the Premises and the other
areas properly as required herein within the applicable notice and cure period
and to the reasonable satisfaction of Landlord, Landlord may, but without
obligation to do so, at any time make such repairs or maintenance without
Landlord having any liability to Tenant for any loss or damage that may accrue
to Tenant's Property or to Tenant's business by reason thereof, except to the
extent any damage is caused by the willful misconduct or gross negligence of
Landlord or its authorized agents and representatives. If Landlord makes such
repairs or maintenance, upon completion thereof Tenant shall pay to Landlord, as
Additional Rent, Landlord's costs and expenses incurred therefor. The
obligations of Tenant hereunder shall survive the expiration of the Term of this
Lease or the earlier termination thereof. Tenant hereby waives any right to
repair at the expense of Landlord under any applicable Laws now or hereafter in
effect with respect to the Premises.

12.     INSURANCE

        12.1 TYPES OF INSURANCE: Tenant shall maintain in full force and effect
at all times during the Term of this Lease, at Tenant's sole cost and expense,
for the protection of Tenant and Landlord, as their interests may appear,
policies of insurance issued by a carrier or carriers reasonably acceptable to
Landlord and its lender (which afford the following coverage's: (i) worker's
compensation and employer's liability, as required by law; (ii) commercial
general liability insurance (occurrence form) providing coverage against any and
all claims for bodily injury and property damage occurring in, on or about the
Premises arising out of Tenant's and Tenant's Representatives' use or occupancy
of the Premises. Such insurance shall include coverage for blanket contractual
liability, fire damage, premises, personal injury, completed operations and
products liability. Such insurance shall have a combined single limit of not
less than Two Million Dollars ($2,000,000) per occurrence with a Three Million
Dollar ($3,000,000) aggregate limit and excess/umbrella insurance in the amount
of Three Million Dollars ($3,000,000). If Tenant has other locations which it
owns or leases, the policy shall include an aggregate limit per location
endorsement, (iii) comprehensive automobile liability insurance with a combined
single limit of at least $1,000,000 per occurrence for claims arising out of any
company owned automobiles; (iv) "all risk" or "special purpose" property
insurance, including without limitation, sprinkler leakage, covering damage to
or loss of any of Tenant's Property and the Tenant Improvements located in, on
or about the Premises, and in addition, coverage for business interruption of
Tenant, together with, if the property of any of Tenant's invitees, vendors or
customers is to be kept in the Premises, warehouse's legal liability or bailee
customers insurance for the full replacement cost of the property belonging to
such parties and located in the Premises. Such insurance shall be written on a
replacement cost basis (without deduction for depreciation) in an amount equal
to one hundred percent (100%) of the full replacement value of the aggregate of
the items referred to in this clause (iv); and (v) such other insurance or
higher limits of liability as is then customarily required for similar types of
buildings within the general vicinity of the Project or as may be reasonably
required by any of Landlord's lenders.

        12.2 INSURANCE POLICIES: Insurance required to be maintained by Tenant
shall be written by companies (i) licensed to do business in the State of
California, (ii) domiciled in the United States of America, and (iii) having a
"General Policyholders Rating" of at least A:X (or such higher rating as may be
required by a lender having a lien on the Premises) as set forth in the most
current issue of "A.M. Best's Rating Guides." Any deductible amounts under any
of the insurance policies required hereunder shall not exceed Five Thousand
Dollars ($5,000). Tenant shall deliver to Landlord certificates of insurance and
true and complete copies of any and all endorsements required herein for all
insurance required to be maintained by Tenant hereunder at the time of execution
of this Lease by Tenant. Tenant shall, at least fifteen (15) days prior to
expiration of each policy, furnish Landlord with certificates of renewal or
"binders" thereof. Each certificate shall expressly provide that such policies
shall not be cancelable or otherwise subject to material modification except
after thirty (30) days prior written notice to the parties named as additional
insureds as required in this Lease (except for cancellation for nonpayment of
premium, in which event cancellation shall not take effect until at least ten
(10) days' notice has been given to Landlord). Tenant shall have the right to
provide insurance coverage which it is obligated to carry pursuant to the terms
of this Lease under a blanket insurance policy, provided such blanket policy
expressly affords coverage for the Premises and for Landlord as required by this
Lease.

        12.3 ADDITIONAL INSUREDS AND COVERAGE: Each of Landlord, Landlord's
property management company or agent, and Landlord's lender(s) having a lien
against the Premises or any other portion of the Project shall be named as
additional insureds or loss payees (as applicable) under all of the policies
required in Section 12.1(ii) and, with respect to the Tenant Improvements, in
Section 12.1(iv) hereof. Additionally, all of such policies shall provide for
severability of interest. All insurance to be maintained by Tenant shall, except
for workers' compensation and employer's liability insurance, be primary,
without right of contribution from insurance maintained by Landlord. Any
umbrella/excess liability policy (which shall be in "following form") shall
provide that if the underlying aggregate is exhausted, the excess coverage will
drop down as primary insurance. The limits of insurance maintained by Tenant
shall not limit Tenant's liability under this Lease. It is the parties'
intention that the insurance to be procured and maintained by Tenant as required
herein shall provide coverage for any and all damage or injury arising from or
related to Tenant's operations of its business and/or Tenant's or Tenant's
Representatives' use of the Premises and any of the areas within the Project.
Notwithstanding anything to the contrary contained herein, to the extent
Landlord's cost of maintaining insurance with respect to the Building and/or any
other buildings within the Project is increased as a result of Tenant's acts,
omissions, Alterations, improvements, use or occupancy of the Premises, Tenant
shall pay one hundred percent (100%) of, and for, each such increase as
Additional Rent.

        12.4 FAILURE OF TENANT TO PURCHASE AND MAINTAIN INSURANCE: If Tenant
fails to obtain and maintain the insurance required herein throughout the Term
of this Lease, Landlord may, but without obligation to do so, purchase the
necessary insurance and pay the premiums therefor. If Landlord so elects to
purchase such insurance, Tenant shall promptly pay to Landlord as Additional
Rent, the amount so paid by Landlord, upon Landlord's demand therefor. In
addition, Landlord may recover from Tenant and Tenant agrees to pay, as
Additional Rent, any and all losses, damages, expenses and costs which Landlord
may sustain or incur by reason of Tenant's failure to obtain and maintain such
insurance.

        12.5 WAIVER OF SUBROGATION: Landlord and Tenant hereby mutually waive
their respective rights of recovery against each other for any loss of, or
damage to, either parties' property to the extent that such loss or damage is
insured by an insurance policy required to be in effect at the time of such loss
or damage. Each party shall obtain any special endorsements, if required by its
insurer, whereby the insurer waives its rights of subrogation against the other
party. This provision is intended to waive fully, and for the benefit of the
parties hereto, any rights and/or claims which might give rise to a right of
subrogation in favor of any insurance carrier.

        12.6 LANDLORD'S INSURANCE: Landlord shall maintain in full force and
effect during the Term of this Lease, subject to reimbursement as provided in
Section 6, policies of insurance which afford such coverages as are
commercially reasonable and as is consistent with other properties in Landlord's
portfolio. Notwithstanding the foregoing, Landlord shall obtain and keep in
force during the Term of this Lease, as an item of Operating Expenses, a policy
or policies in the name of Landlord, with loss payable to Landlord and to the
holders of any mortgages, deeds of trust or ground leases on the Premises
("Lender(s)"), insuring loss or damage to the Building, including all
improvements, fixtures (other than trade fixtures) and permanent additions.
However, all of the Tenant's Property shall be insured by Tenant rather than by
Landlord. The amount of such insurance procured by Landlord shall be equal to at
least eighty percent (80%) of the full replacement cost of the Building,
including all improvements and permanent additions as the same shall exist from
time to time, or the amount required by Lenders. Such policy or polices shall
insure against all risks of direct physical loss or damage (including, without
limitation, the perils of flood and earthquake), including coverage for any
additional costs resulting from debris removal and reasonable amounts of
coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Building required
to be demolished or removed by reason of the enforcement of any building,
zoning, safety or land use laws as the result of a covered cause of loss. If any
such insurance coverage procured by Landlord has a deductible clause, the
deductible shall not exceed commercially reasonable amounts, and in the event of
any casualty, the amount of such deductible shall be an item of Operating
Expenses as so limited. Notwithstanding anything to the contrary contained
herein, to the extent the cost of maintaining insurance with respect to the
Premises is increased as a result of Tenant's acts, omissions, use or occupancy
of the Premises, Tenant shall pay one hundred percent (100%) of, and for, such
increase(s) as Additional Rent. Insurance required to be maintained by Landlord
shall be written by companies (i) licensed to do business in the State of
California, (ii) domiciled in the United States of America, and (iii) having a
"General Policyholders Rating" of A:X or, only with respect to the Landlord
named herein as of the Lease Date, at least A-:VIII, or in either case, such
higher rating as may be required by a lender having a lien on the Premises, as
such ratings are set forth in the most current issue of "A.M. Best's Rating
Guides." Any deductible amounts under any of the insurance policies required
hereunder shall not exceed commercially reasonable amounts. Landlord shall have
the right to provide insurance coverage which it is obligated to carry pursuant
to the terms of this Lease under a blanket insurance policy, provided such
blanket policy expressly affords coverage as required by this Lease.
Additionally, all of such policies shall provide for severability of interest.
The limits of insurance maintained by Landlord shall not limit Landlord's
liability under this Lease.

13.     LIMITATION OF LIABILITY AND INDEMNITY

Except to the extent of damage resulting from the gross negligence or willful
misconduct of Landlord or its authorized representatives, Tenant agrees to
protect, defend (with counsel acceptable to Landlord) and hold Landlord and
Landlord's lenders, partners, members, property management company (if other
than Landlord), agents, directors, officers, employees, representatives,
contractors, successors and assigns and each of their respective partners,
members, directors, heirs, employees, representatives, agents, contractors,
heirs, successors and assigns (collectively, the "Indemnitees") harmless and
indemnify the Indemnitees from and against all liabilities, damages, demands,
penalties, costs, claims, losses, judgments, charges and expenses (including
reasonable attorneys' fees, costs of court and expenses necessary in the
prosecution or defense of any litigation including the enforcement of this
provision) (collectively, "Claims") arising from or in any way related to,
directly or indirectly, (i) Tenant's or Tenant's Representatives' use of the
Premises and other portions of the Project, (ii) the conduct of Tenant's
business, (iii) from any activity, work or thing done, permitted or suffered by
Tenant in or about the Premises, (iv) in any way connected with the Premises,
the Alterations or with the Tenant's Property therein, including, but not
limited to, any liability for injury to person or property of Tenant, Tenant's
Representatives or third party persons, and/or (v) Tenant's failure to perform
any covenant or obligation of Tenant under this Lease. Tenant agrees that the
obligations of Tenant herein shall survive the expiration or earlier termination
of this Lease.

Except to the extent of damage resulting from the gross negligence or willful
misconduct of Landlord or its authorized representatives, to the fullest extent
permitted by law, Tenant agrees that neither Landlord nor any of the Indemnitees
shall at any time or to any extent whatsoever be liable, responsible or in any
way accountable for any loss, liability, injury, death or damage to persons or
property which at any time may be suffered or sustained by Tenant or by any
person(s) whomsoever who may at any time be using, occupying or visiting the
Premises or any other portion of the Project, including, but not limited to, any
acts, errors or omissions of any other tenants or occupants of the Project.
Tenant shall not, in any event or circumstance, be permitted to offset or
otherwise credit against any payments of Rent required herein for matters for
which Landlord may be liable hereunder. Landlord and its authorized
representatives shall not be liable for any interference with light or air, or
for any latent defect in the Premises or the Building.

14.     ASSIGNMENT AND SUBLEASING

        14.1 PROHIBITION: Tenant shall not, without the prior written consent of
Landlord, assign, mortgage, hypothecate, encumber, grant any license or
concession, pledge or otherwise transfer this Lease or any interest herein,
permit any assignment or other such transfer of this Lease or any interest
hereunder by operation of law, sublet the Premises or any part thereof, or
permit the use of the Premises by any persons other than Tenant and Tenant's
Representatives or any Affiliate (as defined in Section 14.8 below) (all of the
foregoing are sometimes referred to collectively as "Transfers" and any person
to whom any Transfer is made or sought to be made is sometimes referred to as a
"Transferee"). No consent to any Transfer shall constitute a waiver of the
provisions of this Section 14, and all subsequent Transfers may be made only
with the prior written consent of Landlord, which consent shall not be
unreasonably withheld, but which consent shall be subject to the provisions of
this Section 14.

        14.2 REQUEST FOR CONSENT: If Tenant seeks to make a Transfer, Tenant
shall notify Landlord, in writing, and deliver to Landlord at least thirty (30)
days (but not more than one hundred eighty (180) days) prior to the proposed
commencement date of the Transfer (the "Proposed Effective Date") the following
information and documents (the "Tenants Notice"): (i) a description of the
portion of the Premises to be transferred (the "Subject Space"); (ii) all of the
terms of the proposed Transfer including without limitation, the Proposed
Effective Date, the name and address of the proposed Transferee, and a copy of
the existing or proposed assignment, sublease or other agreement governing the
proposed Transfer; (iii) current financial statements of the proposed Transferee
certified by an officer, member, partner or owner thereof, and any such other
information as Landlord may then reasonably require, including without
limitation, audited financial statements for the previous three (3) most recent
consecutive fiscal years, if available; (iv) the Plans and Specifications
(defined below), if any; and (v) such other information as Landlord may then
reasonably require. Tenant shall give Landlord the Tenant's Notice by as
provided for in Section 29.9 below, addressed to Landlord at Landlord's Address
specified in the Basic Lease Information. Within twenty (20) days after
Landlord's receipt of the Tenant's Notice (the "Landlord Response Period")
Landlord shall notify tenant, in writing, of its determination with respect to
such


                                       10
<PAGE>   24

requested proposed Transfer and the election to recapture as set forth in
Section 14.5 below, if applicable. If Landlord does not elect to recapture
pursuant to the provisions of Section 14.5 hereof and Landlord does consent to
the requested proposed Transfer, Tenant may thereafter assign its interests in
and to this Lease or sublease all or a portion of the Premises to the same party
and on the same terms as set forth in the Tenant's Notice. If Landlord fails to
respond to Tenant's Notice within Landlord's Response Period, then, after Tenant
delivers to Landlord ten (10) days' written notice (the "Second Response
Period") and Landlord fails to respond thereto prior to the end of the Second
Response Period, the proposed Transfer shall then be deemed approved by
Landlord.

        14.3 CRITERIA FOR CONSENT: Tenant acknowledges and agrees that, among
other circumstances for which Landlord could reasonably withhold consent to a
proposed Transfer, it shall be reasonable for Landlord to withhold its consent
where (a) Tenant is or has been in default of its obligations under this Lease
beyond applicable notice and cure periods, (b) the use to be made of the
Premises by the proposed Transferee is prohibited under this Lease or differs
from the uses permitted under this Lease, (c) the proposed Transferee or its
business is subject to compliance with additional requirements of the ADA beyond
those requirements which are applicable to Tenant, unless the proposed
Transferee shall (1) first deliver plans and specifications for complying with
such additional requirements ( the "Plans and Specifications") and obtain
Landlord's written consent thereto, and (2) comply with all Landlord's
reasonable conditions contained in such consent, (d) the proposed Transferee
does not intend to occupy the majority of the Premises assigned or sublet to it,
(e) Landlord reasonably disapproves of the proposed Transferee's business
operating ability or history, reputation or creditworthiness or the character of
the business to be conducted by the proposed Transferee at the Premises, (f) the
proposed Transferee is a governmental agency or unit or an existing tenant in
the Project (unless Landlord has no comparable space for Lease), (g) the
proposed Transfer would violate any "exclusive" rights of any occupants in the
Project or cause Landlord to violate another agreement or obligation to which
Landlord is a party or otherwise subject, (h) Landlord or Landlord's agent has
shown space in the Project to the proposed Transferee or responded to any
inquiries from the proposed Transferee or the proposed Transferee's agent
concerning availability of space in the Project, at any time within the
preceding six (6) months, (i) Landlord otherwise determines that the proposed
Transfer would have the effect of decreasing the value of the Building or the
Project, or increasing the expenses associated with operating, maintaining and
repairing the Project, (j) the proposed Transferee (i) occupies space in the
Building at the time of the request for consent, (ii) is in active negotiations
with Landlord to lease space in the Building at such time, or (iii) has
negotiated with Landlord during the 6 month period immediately preceding the
Tenant's Notice for available space, (k) the rent proposed to be charged by
Tenant to the proposed Transferee during the term of such Transfer, calculated
using a present value analysis, is less than ninety-five percent (95%) of the
rent then being negotiated by Landlord, at the proposed time of such Transfer,
for comparable space in the Building or any other Building in the Project for a
comparable term, calculated using a present value system, or (l) the proposed
Transferee will use, store or handle Hazardous Materials (defined below) in or
about the Premises of a type, nature or quantity not then reasonably acceptable
to Landlord.

        14.4 EFFECTIVENESS OF TRANSFER AND CONTINUING OBLIGATIONS: Prior to the
date on which any permitted Transfer becomes effective, Tenant shall deliver to
Landlord (i) a counterpart of the fully executed Transfer document, (ii) an
executed Hazardous Materials Disclosure Certificate substantially in the form of
exhibit E hereto (the "Transferee HazMat Certificate"), and (iii) Landlord's
standard form of Consent to Assignment or Consent to Sublease, as applicable,
executed by Tenant and the Transferee in which each of Tenant and the Transferee
confirms its obligations pursuant to this Lease. Failure or refusal of a
Transferee to execute any such consent instrument shall not release or discharge
the Transferee from its obligation to do so or from any liability as provided
herein. The voluntary, involuntary or other surrender of this Lease by Tenant,
or a mutual cancellation by Landlord and Tenant, shall not work a merger, and
any such surrender or cancellation shall, at the option of Landlord, either
terminate all or any existing subleases or operate as an assignment to Landlord
of any or all of such subleases. Each permitted Transferee shall, to the extent
of the obligations of such Transferee under its assignment or subleasing
documents, assume and be deemed to assume this Lease and shall be and remain
liable jointly and severally with Tenant for payment of Rent and for the due
performance of, and compliance with all the terms, covenants, conditions and
agreements herein contained on Tenant's part to be performed or complied with,
for the Term of this Lease. No Transfer shall affect the continuing primary
liability of Tenant (which, following assignment, shall be joint and several
with the assignee), and Tenant shall not be released from performing any of the
terms, covenants and conditions of this Lease. An assignee of Tenant shall
become directly liable to Landlord for all obligations of Tenant hereunder, but
no Transfer by Tenant shall relieve Tenant of any obligations or liability under
this Lease whether occurring before or after such consent, assignment,
subletting or other Transfer. The acceptance of any or all of the Rent by
Landlord from any other person (whether or not such person is an occupant of the
Premises) shall not be deemed to be a waiver by Landlord of any provision of
this Lease or to be a consent to any Transfer. For purposes hereof, if Tenant is
a business entity, direct or indirect transfer of fifty percent (50%) or more of
the ownership interest of the entity (whether in a single transaction or in the
aggregate through more than one transaction) shall be deemed a Transfer and
shall be subject to all the provisions hereof. Any and all options, first rights
of refusal, tenant improvement allowances and other similar rights granted to
Tenant in this lease, if any, shall not be assignable by Tenant unless expressly
authorized in writing by Landlord. Any transfer made without Landlord's prior
written consent, shall, at Landlord's option, be null, void and of no effect,
and shall, at Landlord's option, constitute a material default by Tenant of this
Lease. As Additional Rent hereunder, Tenant shall pay to Landlord, a fee in the
amount of five hundred dollars ($500) plus Tenant shall promptly reimburse
Landlord for actual legal and other expenses incurred by Landlord in connection
with any actual or proposed Transfer.

        14.5 RECAPTURE: Except for a transfer to an Affiliate (as defined in
Section 14.8 below), if the Transfer (i) by itself or taken together with then
existing or pending Transfers covers or totals, as the case may be, more than
fifty percent (50%) of the rentable square feet of the Premises, and (ii) is for
a term which by itself or taken together with then existing or pending Transfers
is for the period then remaining in the Term of this Lease as of the time of the
Proposed Effective Date, then Landlord shall have the right, to be exercised by
giving written notice to Tenant, to recapture the Subject Space described in the
Tenant's Notice. If such recapture notice is given, it shall serve to terminate
this Lease with respect to the proposed Subject Space, or, if the proposed
Subject Space covers all the Premises, it shall serve to terminate the entire
Term of this Lease, in either case, as of the Proposed Effective Date. However,
no termination of this Lease with respect to part or all of the Premises shall
become effective without the prior written consent, where necessary, of the
holder of each deed of trust encumbering the Premises or any other portion of
the Project. If this lease is terminated pursuant to the foregoing provisions
with respect to less than the entire Premises, the Rent shall be adjusted on the
basis of the proportion of rentable square feet retained by Tenant to the
rentable square feet originally demised, Tenant's Share shall be decreased
accordingly, the amount of the Security Deposit and Letter of Credit shall be
equitably reduced and Tenant shall thereafter be relieved of all liabilities for
the recapture space, and this Lease as so amended shall continue thereafter in
full force and effect.


                                       11
<PAGE>   25
        14.6 TRANSFER PREMIUM: If Landlord consents to a Transfer, as a
condition thereto which the Tenant hereby agrees is reasonable, Tenant shall pay
to Landlord, as Additional Rent any "Transfer Premium" received by Tenant from
such Transferee. The term "Transfer Premium" shall mean all rent, additional
rent and other consideration payable by such Transferee which either Initially
or over the term of the Transfer exceeds the Rent or pro rata portion of the
Rent, as the case may be, for such space reserved in the Lease. Tenant shall pay
the Landlord monthly, as Additional Rent, at the same time as the monthly
installments of Rent are payable hereunder, seventy-five percent (75%) of the
Transfer Premium after deduction of actual reasonable commission costs only.

        14.7 WAIVER: Notwithstanding any Transfer, or any indulgences, waivers
or extensions of time granted by Landlord to any Transferee, or failure by
Landlord to take action against any Transferee, Tenant agrees that Landlord may,
at its option, proceed against Tenant without having taken action against or
joined such Transferee, except that Tenant shall have the benefit of any
indulgences, waivers and extensions of time granted to any such Transferee.

        14.8 AFFILIATED COMPANIES/RESTRUCTURING OF BUSINESS ORGANIZATION: The
assignment or subletting by Tenant of all or any portion of this Lease or the
Premises to (i) a parent or subsidiary of Tenant, or (ii) any person or entity
which controls, is controlled by or under the common control with Tenant, or
(iii) any entity which purchases all or substantially all of the assets of
Tenant, or (iv) any entity into which Tenant is merged or consolidated (all such
persons or entities described in clauses (i), (ii), (iii) and (iv) being
sometimes herein referred to as "Affiliates") shall not be deemed a Transfer
under the Section 14 (hence, the aforesaid events shall not be subject to
obtaining Landlord's prior consent; Landlord shall not have any right to receive
any Transfer Premium in connection therewith; and Landlord shall not have the
recapture rights described in Section 14.5 above), provided in all instances
that:

               14.8.1 any such Affiliate was not formed as a subterfuge to avoid
the obligations of this Section 14;

               14.8.2 Tenant shall give Landlord prior notice of any such
assignment or sublease to an Affiliate;

               14.8.3 the successor of Tenant has as of the effective date of
any such assignment or sublease a tangible net worth and net assets, in the
aggregate, computed in accordance with generally accepted accounting principles
(but excluding goodwill as an asset), which is sufficient to meet the
obligations of Tenant under this Lease, as reasonably determined by Landlord;

               14.8.4 any such assignment or sublease shall be subject to all of
the terms and provisions of this Lease, and such assignee or sublessee (i.e. any
such Affiliate), other than in the case of an Affiliate resulting from a merger
or consolidation as described in Section 14.8(iv) above, shall assume, in a
written document reasonably satisfactory to Landlord and delivered to Landlord
upon or prior to the effective date of such assignment or sublease, all the
obligations of Tenant under this Lease; and

               14.8.5 Tenant and any guarantor shall remain fully liable for all
obligations to be performed by Tenant under this Lease, except in the case of an
Affiliate resulting from the acquisition of all or substantially all of the
assets of Tenant described in Section 14.8(iii) or from a merger or
consolidation as described in Section 14.8(iv) above.

15.     SUBORDINATION

To the fullest extent permitted by law, this Lease, the rights of Tenant under
this Lease and Tenant's leasehold interest shall be subject and subordinate at
all times to: (i) all ground leases or underlying leases which may now exist or
hereafter be executed affecting the Building, the Lot, or any other portion of
the Project, and (ii) the lien of any mortgage or deed of trust which may now or
hereafter exist for which the Building, the Lot, ground leases or underlying
leases, any other portion of the Project or Landlord's interest or estate in any
of said items is specified as security. Tenant hereby acknowledges that as of
the date on which Landlord and Tenant execute this Lease there is a deed of
trust encumbering, and in force against, the Premises (i.e. the Building) in
favor of U.S. Bank National Association (the "Current Lender"). If Tenant so
requests, within a reasonable period after the parties execute this Lease but in
no event later than forty-five (45) days after such request, Landlord shall
cause the Current Lender to execute a subordination, non-disturbance and
attornment agreement substantially in the form of Exhibit I attached hereto,
entitled "Subordination, Non-Disturbance and Attornment Agreement." If Landlord
at any time during the Term of the Lease causes the Premises and the Building to
be encumbered by a new deed of trust or mortgage pursuant to which the
beneficiary of such deed of trust or mortgage is a party or entity other than
the Current Lender, the parties acknowledge and agree that the form of any
non-disturbance and attornment agreement that may be requested to be executed
and delivered by Tenant in connection therewith will not be the "Non-Disturbance
and Attornment Agreement" attached to the Lease as Exhibit I, but such agreement
will be a commercially reasonable form which will not adversely affect Tenants
rights hereunder. Notwithstanding the foregoing, Landlord or any such ground
lessor, mortgagee, or any beneficiary shall have the right to require this Lease
be superior to any such ground leases or underlying leases or any such liens,
mortgage or deed of trust. If any ground lease or underlying lease terminates
for any reason or any mortgage or deed of trust is foreclosed or a conveyance in
lieu of foreclosure is made for any reason, Tenant shall attorn to and become
the Tenant of the successor in interest to Landlord, provided such successor in
interest will not disturb Tenant's use, occupancy or quiet enjoyment of the
Premises if Tenant is not in material default of the terms and provisions of
this Lease beyond any applicable notice and cure period. The successor in
interest to Landlord following foreclosure, sale or deed in lieu thereof shall
not be: (a) liable for any act or omission of any prior lessor or with respect
to events occurring prior to acquisition of ownership; (b) subject to any
offsets or defenses which Tenant might have against any prior lessor, (c) bound
by prepayment of more than one (1) month's Rent, except in those instances when
Tenant pays Rent quarterly in advance pursuant to Section 8 hereof, then not
more than three months' Rent; or (d) liable to Tenant for any Security Deposit
not actually received by such successor in interest to the extent any portion or
all of such Security Deposit has not already been forfeited by, or refunded to,
Tenant. Landlord shall be liable to Tenant for all or any portion of the
Security Deposit not forfeited by, or refunded to Tenant, until and unless
Landlord transfers such Security Deposit to the successor in interest. Tenant
covenants and agrees to execute (and acknowledge if required by Landlord, any
lender or ground lessor) and deliver, within ten (10) days of a demand or
request by Landlord and in the form reasonably requested by Landlord, ground
lessor, mortgagee or beneficiary, any additional documents evidencing the
priority or subordination of this Lease with respect to any such ground leases
or underlying leases or the lien of any such mortgage or deed of trust.

<PAGE>   26

16.     RIGHT OF ENTRY

Landlord and its agents shall have the right to enter the Premises at all
reasonable times, upon reasonable prior notice, for purposes of inspection,
exhibition, posting of notices, investigation, replacements, repair, maintenance
and alteration. It is further agreed that Landlord shall have the right to use
any and all means Landlord deems necessary to enter the Premises in an
emergency. Landlord shall have the right to place "for rent" or "for lease"
signs on the outside of the Premises, the Building and in the Common Areas
during the last twelve (12) months of the Lease only. Landlord shall also have
the right to place "for sale" signs on the outside of the Building and in the
Common Areas. Tenant hereby waives any Claim from damages or for any injury or
inconvenience to or interference with Tenant's business, or any other loss
occasioned thereby except for any Claim for any of the foregoing arising out of
the gross negligence or willful misconduct of Landlord or its authorized
representatives.

17.     ESTOPPEL CERTIFICATE

Tenant shall execute (and acknowledge if required by any lender or ground
lessor) and deliver to Landlord, within ten (10) days after Landlord provides
such to Tenant, a statement in writing certifying that this Lease is unmodified
and in full force and effect (or, if modified, stating the nature of such
modification), the date to which the Rent and other charges are paid in advance,
if any, acknowledging that there are not, to Tenant's knowledge, any uncured
defaults on the part of Landlord hereunder or specifying such defaults as are
claimed, and such other matters as Landlord may reasonably require. Any such
statement may be conclusively relied upon by Landlord and any prospective
purchaser or encumbrancer of the Building or other portions of the Project.
Tenant's failure to deliver such statement within such time shall be conclusive
upon the Tenant that (a) this Lease is in full force and effect, without
modification except as may be represented by Landlord; (b) there are no uncured
defaults in Landlord's performance; and (c) not more than one month's Rent has
been paid in advance, except in those instances when Tenant pays Rent quarterly
in advance pursuant to Section 8 hereof, then not more than three months' Rent
has been paid in advance.

18.     TENANT'S DEFAULT

The occurrence of any one or more of the following events shall, at Landlord's
option, constitute a material default by Tenant of the provisions of this Lease:

        18.1 The abandonment of the Premises by Tenant or the vacation of the
Premises by Tenant which would cause any insurance policy to be invalidated or
otherwise lapse;

        18.2 The failure by Tenant to make any payment of Rent, Additional Rent
or any other payment required hereunder, or to fulfill any obligation under this
Lease which endangers or threatens imminent damage or injury to life or
property, within five (5) business days of receipt of written notice that such
amount is past due or of such failure to fulfill any obligation;

        18.3 The failure by Tenant to observe, perform or comply with any of the
conditions, covenants or provisions of this Lease (except failure to make any
payment of Rent and/or Additional Rent) and such failure is not cured within (i)
thirty (30) days of the date on which Landlord delivers written notice of such
failure to Tenant for all failures other than with respect to (a) Hazardous
Materials (defined in Section 27 hereof), (b) Tenant making the repairs,
maintenance and replacements required under the provisions of Section 11.1
hereof, which endangers or threatens imminent damage or injury to life or
property, or (c) the timely delivery by Tenant of a subordination,
non-disturbance and attornment agreement (an "SNDA"), a counterpart of a fully
executed Transfer document and a consent thereto (collectively, the "Transfer
Documents"), an estoppel certificate and insurance certificates, (ii) ten (10)
days of the date on which Landlord delivers written notice of such failure to
Tenant for all failures in any way related to Hazardous Materials or Tenant
failing to timely make the repairs, maintenance or replacements required by
Section 11.1 which endangers or threatens imminent damage or injury to life or
property, and (iii) the time period, if any, specified in the applicable
sections of this Lease with respect to subordination, assignment and sublease,
estoppel certificates and insurance. However, Tenant shall not be in default of
its obligations hereunder if such failure (other than any failure of Tenant to
timely and properly make the repairs, maintenance, or replacements required by
Section 11.1 which endangers or threatens imminent damage or injury to life or
property, or timely deliver an SNDA, the Transfer Documents, an estoppel
certificate or insurance certificates, for which no additional cure period shall
be given to Tenant) cannot reasonably be cured within such thirty (30) or ten
(10) day period, as applicable, and Tenant promptly commences, and thereafter
diligently proceeds with same to completion, all actions necessary to cure such
failure as soon as is reasonably possible, but in no event shall the completion
of such cure be later than ninety (90) days after the date on which Landlord
delivers to Tenant written notice of such failure, unless Landlord, acting
reasonably and in good faith, otherwise expressly agrees in writing to a longer
period of time based upon the circumstances relating to such failure as well as
the nature of the failure and the nature of the actions necessary to cure such
failure; or

        18.4 The making of a general assignment by Tenant for the benefit of
creditors, the filing of a voluntary petition by Tenant or the filing of an
involuntary petition by any of Tenant's creditors seeking the rehabilitation,
liquidation, or reorganization of Tenant under any law relating to bankruptcy,
insolvency or other relief of debtors and, in the case of an involuntary action,
the failure to remove or discharge the same within sixty (60) days of such
filing, the appointment of a receiver or other custodian to take possession of
substantially all of Tenant's assets or this leasehold, Tenant's insolvency or
inability to pay Tenant's debts or failure generally to pay Tenant's debts when
due, any court entering a decree or order directing the winding up or
liquidation of Tenant or of substantially all of Tenant's assets, Tenant taking
any action toward the dissolution or winding up of Tenant's affairs, the
cessation or suspension of Tenant's use of the Premises, or the attachment,
execution or other judicial seizure of substantially all of Tenant's assets or
this leasehold.

19.     REMEDIES FOR TENANT'S DEFAULT

        19.1 LANDLORD'S RIGHTS: In the event of Tenant's material default under
this Lease, Landlord may terminate Tenant's right to possession of the Premises
by any lawful means in which case upon delivery of written notice by Landlord
this Lease shall terminate on the date specified by Landlord in such notice and
Tenant shall immediately surrender possession of the Premises to Landlord. In
addition, the Landlord shall have the immediate right of re-entry whether or not
this Lease is terminated, and if this right of re-entry is exercised following
abandonment of the Premises by Tenant, Landlord may consider any of Tenant's
Property left on the Premises to also have been abandoned. No reentry or taking
possession of the Premises by Landlord pursuant to this Section 19 shall be
construed as an election to


                                       13
<PAGE>   27

terminate this Lease unless a written notice of such intention is given to
Tenant. If Landlord relets the Premises or any portion thereof, Tenant shall be
liable immediately to Landlord for all costs Landlord incurs in reletting the
Premises or any part thereof, including, without limitation, broker's
commissions, expenses of cleaning, redecorating, and further improving the
Premises and other similar costs (collectively, the "Reletting Costs"). Any and
all of the Reletting Costs shall be fully chargeable to Tenant and shall not be
prorated or otherwise amortized in relation to any new lease for the Premises or
any portion thereof. Reletting may be for a period shorter or longer than the
remaining term of this Lease. In no event shall Tenant be entitled to any excess
rent received by Landlord. No act by Landlord other than giving written notice
to Tenant shall terminate this Lease. Acts of maintenance, efforts to relet the
Premises or the appointment of a receiver on Landlord's initiative to protect
Landlord's interest under this Lease shall not constitute a termination of
Tenant's right to possession. So long as this Lease is not terminated, Landlord
shall have the right to remedy any default of Tenant, to maintain or improve the
Premises, to cause a receiver to be appointed to administer the Premises and new
or existing subleases and to add to the Rent payable hereunder all of Landlord's
reasonable costs in so doing, with interest at the maximum rate permitted by law
from the date of such expenditure.

        19.2 DAMAGES RECOVERABLE: If Tenant breaches this Lease and abandons the
Premises before the end of the Term, or if Tenant's right to possession is
terminated by Landlord because of a breach or default under this Lease, then in
either such case, Landlord may recover from Tenant all damages suffered by
Landlord as a result of Tenant's failure to perform its obligations hereunder,
including without limitation, the unamortized cost of any Tenant improvements
constructed by or on behalf of Tenant pursuant to Exhibit B hereto to the extent
Landlord has paid for such improvements, the unamortized portion of any broker's
or leasing agent's commission incurred with respect to the leasing of the
Premises to Tenant for the balance of the Term of the Lease remaining after the
date on which Tenant is in default of its obligations hereunder, and all
Reletting Costs, and the worth at the time of the award (computed in accordance
with paragraph (3) of Subdivision (a) of Section 1951.2 of the California Civil
Code) of the amount by which the Rent then unpaid hereunder for the balance of
the Lease Term exceeds the amount of such loss of Rent for the same period which
Tenant proves could be reasonably avoided by Landlord and in such case, Landlord
prior to the award, may relet the Premises for the purpose of mitigating damages
suffered by Landlord because of Tenant's failure to perform its obligations
hereunder; provided, however, that even though Tenant has abandoned the Premises
following such breach, this Lease shall nevertheless continue in full force and
effect for as long as Landlord does not terminate Tenant's right of possession,
and until such termination, Landlord shall have the remedy described in Section
1951.4 of the California Civil Code (Landlord may continue this Lease in effect
after Tenant's breach and abandonment and recover Rent as it becomes due, if
Tenant has the right to sublet or assign, subject only to reasonable
limitations) and may enforce all its rights and remedies under this Lease,
including the right to recover the Rent from Tenant as it becomes due hereunder.
The "worth at the time of the award" within the meaning of Subparagraphs (a)(1)
and (a)(2) of Section 1951.2 of the California Civil Code shall be computed by
allowing interest at the rate of ten percent (10%) per annum. Tenant waives
redemption or relief from forfeiture under California Code of Civil Procedure
Sections 1174 and 1179 (or any successor or substitute statute), or under any
other present or future law, in the event Tenant is evicted or Landlord takes
possession of the Premises by reason of any default of Tenant hereunder, Tenant
hereby waives for Tenant and for all those claiming under Tenant all rights now
or hereafter existing to redeem by order or judgment of any court or by any
legal process or writ, Tenant's right of occupancy of the Premises after any
termination of this Lease.

        19.3 RIGHTS AND REMEDIES CUMULATIVE: The foregoing rights and remedies
of Landlord are not exclusive; they are cumulative in addition to any rights and
remedies now or hereafter existing at law, in equity by statute or otherwise, or
to any equitable remedies Landlord may have, and to any remedies Landlord may
have under bankruptcy laws or laws affecting creditors' rights generally. In
addition to all remedies set forth above, if Tenant materially defaults under
this Lease, all options granted to Tenant hereunder shall automatically
terminate, unless otherwise expressly agreed to in writing by Landlord.

20.     HOLDING OVER

If Tenant holds over after the expiration of the Lease Term hereof, with or
without the express or implied consent of Landlord, such tenancy shall be from
month-to-month only, and shall not constitute a renewal hereof or an extension
for any further term, and in such case Base Rent shall be payable at a monthly
rate equal to (a) for the first month of any such holding over, one hundred
fifty percent (150%), and (b) for any subsequent such holding over, two hundred
percent (200%), in either case, of the greater of (i) the Base Rent applicable
during the last rental period of the Lease Term under this Lease or (ii) the
fair market rental rate for the Premises as of the commencement of such holdover
period. Such month-to-month tenancy shall be subject to every other term,
covenant and agreement contained herein. Landlord hereby expressly reserves the
right to require Tenant to surrender possession of the Premises to Landlord as
provided in this Lease upon the expiration or other termination of this Lease.
The provisions of this Section 20 shall not be deemed to limit or constitute a
waiver of any other rights or remedies of Landlord provided herein or at law. If
Tenant fails to surrender the Premises upon the termination or expiration of
this Lease, in addition to any other liabilities to Landlord accruing therefrom,
Tenant shall protect, defend, indemnify and hold Landlord harmless from all
Claims resulting from such failure.

21.     LANDLORD'S DEFAULT

Landlord shall not be considered in default of this Lease unless Landlord fails
within a reasonable time to perform an obligation required to be performed by
Landlord hereunder. For purposes hereof, a reasonable time shall not be less
than thirty (30) days after receipt by Landlord of written notice specifying the
nature of the obligation Landlord has not performed; provided, however, that if
the nature of Landlord's obligation is such that more than thirty (30) days,
after receipt of written notice, is reasonably necessary for its performance,
then Landlord shall not be in default of this Lease if performance of such
obligation is commenced within such thirty (30) day period and thereafter
diligently pursued to completion.

22.     PARKING

Tenant may use the number of non-designated and non-exclusive parking spaces
specified in the Basic Lease Information. Landlord shall exercise reasonable
efforts to ensure that such spaces are available to Tenant for its use, but
Landlord shall not be required to enforce Tenant's right to use the same. In no
event shall Tenant or any of Tenant's Representatives park or permit any parking
of vehicles overnight.


                                       14
<PAGE>   28

23.     TRANSFER OF LANDLORD'S INTEREST

If there is any sale or other transfer of the Premises or any other portion of
the Project by Landlord or any of Landlord's interest therein, Landlord shall
automatically be entirely released from all liability under this Lease and
Tenant agrees to look solely to such transferee for the performance of
Landlord's obligations hereunder after the date of such transfer provided such
transferee agrees in writing to perform the obligations of Landlord hereunder
from and after the date of such transfer. A ground lease or similar long term
lease by Landlord of the entire Building or Lot, of which the Premises are a
part, shall be deemed a sale within the meaning of this Section 23. Tenant
agrees to attorn to such new owner provided such new owner does not disturb
Tenant's use, occupancy or quiet enjoyment of the Premises so long as Tenant is
not in material default of any of the provisions of this Lease.

24.     WAIVER

No delay or omission in the exercise of any right or remedy of either party on
any default by the other party shall impair such a right or remedy or be
construed as a waiver. The subsequent acceptance of Rent by Landlord after
default by Tenant of this Lease shall not be deemed a waiver of such default,
other than a waiver of timely payment for the particular Rent payment involved,
and shall not prevent Landlord from maintaining an unlawful detainer or other
action based on such breach. No payment by Tenant or receipt by Landlord of a
lesser amount than the monthly Rent and other sums due hereunder shall be deemed
to be other than on account of the earliest Rent or other sums due, nor shall
any endorsement or statement on any check or accompanying any check or payment
be deemed an accord and satisfaction; and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
Rent or other sum or pursue any other remedy provided in this Lease. No failure,
partial exercise or delay on the part of the Landlord in exercising any right,
power or privilege hereunder shall operate as a waiver thereof.

25.     CASUALTY DAMAGE

        25.1 CASUALTY. If the Premises or any part (excluding any of Tenant's
Property, any Tenant Improvements and any Alterations installed by or for the
benefit of Tenant (collectively, the "Tenant's FF&E")] shall be damaged or
destroyed by fire or other casualty, Tenant shall give immediate written notice
thereof to Landlord. Within forty-five (45) days after receipt by Landlord of
such notice, Landlord shall notify Tenant, in writing, whether the necessary
repairs can reasonably be made, as reasonably determined by Landlord: (a) within
one hundred eighty (180) days; (b) in more than one hundred eighty (180) days
but in less than two hundred seventy (270) days; or (c) in more than two
hundred seventy (270) days, from the date of such notice.

               25.1.1 MINOR INSURED DAMAGE. If the Premises (other than the
Tenant's FF&E) are damaged only to such extent that repairs, rebuilding and/or
restoration can be reasonably completed within one hundred eighty (180) days,
this Lease shall not terminate and, provided that insurance proceeds are
available and paid to Landlord to fully repair the damage and/or Tenant
otherwise voluntarily contributes any shortfall thereof to Landlord, Landlord
shall repair the Premises to substantially the same condition that existed prior
to the occurrence of such casualty, except Landlord shall not be required to
rebuild, repair, or replace any of Tenant's FF&E. The Rent payable hereunder
shall be abated proportionately from the date of such damage until any and all
repairs required herein to be made by Landlord are substantially completed but
such abatement shall only be to the extent of the portion of the Premises which
is actually rendered unusable and unfit for occupancy and only during the time
Tenant is not actually using same for Tenants customary operations,

               25.1.2 INSURED DAMAGE REQUIRING MORE THAN 180 DAYS TO REPAIR. If
the Premises (other than the Tenant's FF&E) are damaged only to such extent that
repairs, rebuilding and/or restoration can be reasonably completed, as
reasonably determined by Landlord, in more than one hundred eighty (180) days
but in less than two hundred seventy (270) days, then Landlord shall have the
option of: (a) terminating the Lease effective upon making the determination of
the extent of such damage, in which event the Rent shall be abated from the date
of the occurrence of such damage, provided Tenant diligently proceeds to and
expeditiously vacates the Premises (but, in all events Tenant shall diligently
proceed to expeditiously vacate the Premises); or (b) electing to repair the
Premises to substantially the same condition that existed prior to the
occurrence of such casualty, provided insurance proceeds are available and paid
to Landlord and Tenant otherwise voluntarily contributes any shortfall thereof
to Landlord to fully repair the damage (except that Landlord shall not be
required to rebuild, repair, or replace any of Tenant's FF&E). The Rent payable
hereunder shall be abated proportionately from the date of such damage until any
and all repairs required herein to be made by Landlord are substantially
completed but such abatement shall only be to the extent of the portion of the
Premises which is actually rendered unusable and unfit for occupancy and only
during the time Tenant is not actually using same for Tenant's customary
operations. If Landlord fails to substantially complete such repairs within two
hundred seventy (270) days after the date on which Landlord is notified by
Tenant of the occurrence of such casualty [such 270-day period to be extended
for delays caused by Tenant or any of Tenant's Representatives ("Tenant Delays")
or any force majeure events, which events shall include, but not be limited to,
acts or events beyond Landlord's and/or its contractors' control, acts of God,
earthquakes, strikes, lockouts, riots, boycotts, casualties not caused by
landlord or Tenant, discontinuance of any utility or other service required for
performance of the work, moratoriums, governmental delays in issuing permits,
governmental agencies and weather, and the lack of availability or shortage of
materials ("Force Majeure Delays")], Tenant may within ten (10) business days
after expiration of such two hundred seventy (270) day period (as same may be
extended), terminate this Lease by delivering written notice to Landlord as
Tenant's exclusive remedy, whereupon all rights of Tenant hereunder shall cease
and terminate ten (10) business days after Landlord's receipt of such notice,
and Tenant shall diligently proceed to expeditiously vacate the Premises.

               25.1.3 MAJOR INSURED DAMAGE. If the Premises (other than the
Tenant's FF&E) are damaged to such extent that repairs, rebuilding and/or
restoration cannot be reasonably completed, as reasonably determined by
Landlord, within two hundred seventy (270) days, then either Landlord or Tenant
may terminate this Lease by giving written notice within twenty (20) days after
notice from Landlord regarding the time period of repair. If either party
notifies the other of its intention to so terminate the Lease, then this Lease
shall terminate and the Rent shall be abated from the date of the occurrence of
such damage, and Tenant shall diligently proceed to expeditiously vacate the
Premises. If neither party elects to terminate this Lease, Landlord shall
promptly commence and diligently prosecute to completion the repairs to the
Premises, provided insurance proceeds are available and paid to Landlord to
fully repair the damage or Tenant voluntarily contributes any shortfall thereof
to Landlord (except that Landlord shall not be required to rebuild, repair, or
replace any of Tenant's FF&E). During the time when Landlord is prosecuting such
repairs to substantial completion, the Rent payable hereunder shall be abated
proportionately from the date of such damage until any and all repairs required
herein to be made by Landlord are substantially completed but such abatement
shall only be to the extent of the portion of the Premises which Is actually
rendered unusable and unfit for occupancy and only during


                                       15
<PAGE>   29

the time Tenant is not actually using same for Tenant's customary operations. If
Landlord fails to substantially complete such repairs within twelve (12) months
after the date on which Landlord is notified by Tenant of the occurrence of such
casualty [such 12-month period to be extended for Tenant Delays or any Force
Majeure Delays], Tenant may within ten (10) business days after expiration of
such 12-month period (as same may be extended), terminate this Lease by
delivering written notice to Landlord as Tenant's exclusive remedy, whereupon
all rights of Tenant hereunder shall cease and terminate ten (10) business days
after Landlord's receipt of such notice and Tenant shall diligently proceed to
expeditiously vacate the Premises.

               25.1.4 DAMAGE NEAR END OF TERM. Notwithstanding anything to the
contrary contained in this Lease except for the provisions of Section 25.3
below, if the Premises are substantially damaged or destroyed during the last
year of then applicable term of this Lease, either Landlord or Tenant may, at
their option, cancel and terminate this Lease by giving written notice to the
other party of its election to do so within thirty (30) days after receipt by
Landlord of notice from Tenant of the occurrence of such casualty, unless Tenant
renews the Lease, in which case Landlord shall not have the right to terminate.
If either party so elects to terminate this Lease, all rights of Tenant
hereunder shall cease and terminate ten (10) days after Tenant's receipt or
delivery of such notice, as applicable, and Tenant shall immediately vacate the
Premises and surrender possession thereof to Landlord.

        25.2 DEDUCTIBLE AND UNINSURED CASUALTY. Tenant shall be responsible for
and shall pay to Landlord, as Additional Rent, the deductible amounts under the
insurance policies obtained by Landlord and Tenant under this Lease if the
proceeds of which are used to repair the Premises as contemplated in this
Section 25. Notwithstanding the foregoing, if other portions of the Building are
also damaged by said casualty and insurance proceeds are payable therefor, then
Tenant shall only pay Tenant's proportionate share of the deductible as
reasonably determined by Landlord. If any portion of the Premises is damaged and
is not fully covered by the aggregate of insurance proceeds received by Landlord
and any applicable deductible, and Tenant does not voluntarily contribute any
shortfall thereof to Landlord, or if the holder of any indebtedness secured by
the Premises requires that the insurance proceeds be applied to such
indebtedness, then Landlord or Tenant shall have the right to terminate this
Lease by delivering written notice of termination to the other party within
thirty (30) days after the date of notice to Tenant of any such event, whereupon
all rights and obligations of Tenant shall cease and terminate hereunder, except
for those obligations expressly provided for in this Lease to survive such
termination of the Lease.

        25.3 TENANT'S FAULT AND LENDER'S RIGHTS. Notwithstanding anything to the
contrary contained herein, but subject to the provisions of Section 12.5 above,
if the Premises (other than Tenant's FF&E) or any other portion of the Building
be damaged by fire or other casualty resulting from the intentional or negligent
acts or omissions of Tenant or any of Tenant's Representatives, (i) the Rent
shall not be diminished during the repair of such damage, (ii) Tenant shall not
have any right to terminate this Lease due to the occurrence of such casualty or
damage, and (iii) Tenant shall be liable to Landlord for the cost and expense of
the repair and restoration of all or any portion of the Budding caused thereby
(including, without limitation, any deductible) to the extent such cost and
expense is not covered by insurance proceeds. Notwithstanding anything to the
contrary contained herein, if the holder of any indebtedness secured by the
Premises or any other portion of the Project requires that the insurance
proceeds be applied to such indebtedness, then either Tenant or Landlord shall
have the right to terminate this Lease by delivering written notice of
termination to Tenant within thirty (30) days after the date of written notice
to the other of any such event, whereupon all rights and obligations of the
other shall cease and terminate hereunder, except for those obligations
expressly provided for in this Lease to survive such termination of the Lease.

        25.4 TENANT'S WAIVER. Landlord shall not be liable for any inconvenience
or annoyance to Tenant, injury to the business of Tenant, loss of use of any
part of the Premises by Tenant or loss of Tenant's Property, resulting in any
way from such damage, destruction or the repair thereof, except that, Landlord
shall allow Tenant a fair diminution of Rent during the time and to the extent
the Premises are actually unusable and unfit for occupancy as specifically
provided above in this Section 25. With respect to any damage or destruction
which Landlord is obligated to repair or may elect to repair, Tenant hereby
waives all rights to terminate this Lease or offset any amounts against Rent
pursuant to rights accorded Tenant by any law currently existing or hereafter
enacted, including but not limited to, all rights pursuant to the provisions of
Sections 1932(2.), 1933(4.), 1941 and 1942 of the California Civil Code, as the
same may be amended or supplemented from time to time.

26.     CONDEMNATION

If a substantial portion of the Premises is condemned by eminent domain,
inversely condemned or sold in lieu of condemnation for any public or
quasi-public use or purpose ("Condemned") such that Tenant reasonably determines
that it cannot use the remainder portion for the conduct of its business such
that it was prior to the event, then Tenant or Landlord may terminate this Lease
as of the date when physical possession of the Premises is taken and title vests
in such condemning authority, and Rent shall be adjusted to the date of
termination. Tenant shall not because of such condemnation assert any claim
against Landlord or the condemning authority for any compensation because of
such condemnation, and Landlord shall be entitled to receive the entire amount
of any award without deduction for any estate of interest or other interest of
Tenant; provided, however, the foregoing provisions shall not preclude Tenant,
at Tenant's sole cost and expense, from obtaining any separate award to Tenant
for loss of or damage to Tenant's Property or for damages for cessation or
interruption of Tenant's business provided such award is separate from
Landlord's award and provided further such separate award does not diminish nor
otherwise impair the award otherwise payable to Landlord. In addition to the
foregoing, Tenant shall be entitled to seek compensation for the relocation
costs recoverable by Tenant pursuant to the provisions of California Government
Code Section 7262. If neither party elects to terminate this Lease, Landlord
shall, if necessary, promptly proceed to restore the Premises or the Building,
as applicable, to substantially its same condition prior to such partial
condemnation, allowing for the reasonable effects of such partial condemnation,
and a proportionate allowance shall be made to Tenant, as solely determined by
Landlord, for the Rent corresponding to the time during which, and to the part
of the Premises of which, Tenant is deprived on account of such partial
condemnation and restoration Landlord shall not be required to spend funds for
restoration in excess of the amount received by Landlord as compensation
awarded.

27.     ENVIRONMENTAL MATTERS/HAZARDOUS MATERIALS

        27.1 HAZARDOUS MATERIALS DISCLOSURE CERTIFICATE: Prior to executing this
Lease, Tenant has delivered to Landlord Tenant's executed initial Hazardous
Materials Disclosure Certificate (the "Initial HazMat Certificate"), a copy of
which is attached hereto as Exhibit E. Tenant covenants, represents and warrants
to Landlord that the information in the Initial HazMat Certificate is true and
correct and accurately describes the use(s) of Hazardous Materials which will be
made and/or used on the Premises by Tenant. Tenant shall, commencing with the
date which is one year from the


                                       16
<PAGE>   30

Commencement Date and continuing every year thereafter, deliver to Landlord, an
executed Hazardous Materials Disclosure Certificate ("the "HazMat Certificate")
describing Tenant's then present use of Hazardous Materials on the Premises, and
any other reasonably necessary documents as requested by Landlord. The HazMat
Certificates required hereunder shall be in substantially the form attached
hereto as Exhibit E.

        27.2 DEFINITION OF HAZARDOUS MATERIALS: As used in this Lease, the term
Hazardous Materials shall mean and include (a) any hazardous or toxic wastes,
materials or substances, and other pollutants or contaminants, which are or
become regulated by any Environmental Laws; (b) petroleum, petroleum by
products, gasoline, diesel fuel, crude oil or any fraction thereof; (c) asbestos
and asbestos containing material, in any form, whether friable or non-friable;
(d) polychlorinated biphenyl's; (e) radioactive materials; (f) lead and
lead-containing materials; (g) any other material, waste or substance displaying
toxic, reactive, ignitable or corrosive characteristics, as all such terms are
used in their broadest sense, and are defined or become defined by any
Environmental Law (defined below); or (h) any materials which cause or threatens
to cause a nuisance upon or waste to any portion of the Project or any
surrounding property; or poses or threatens to pose a hazard to the health and
safety of persons on the Premises, any other portion of the Project or any
surrounding property. For purposes of this Lease, the term "Hazardous Materials"
shall not include nominal amounts of ordinary household cleaners, office
supplies and janitorial supplies which are not actionable under any
Environmental Laws.

        27.3 PROHIBITION; ENVIRONMENTAL LAWS: Tenant shall not be entitled to
use or store any Hazardous Materials on, in, or about any portion of the
Premises and the Project without, in each instance, obtaining Landlord's prior
written consent thereto. If Landlord, in its sole discretion, consents to any
such usage or storage, then Tenant shall be permitted to use and/or store only
those Hazardous Materials that are necessary for Tenant's business and to the
extent disclosed in the HazMat Certificate and as expressly approved by Landlord
in writing. Any such usage and storage may only be to the extent of the
quantities of Hazardous Materials as specified in the then applicable HazMat
Certificate as expressly approved by Landlord. In all events such usage and
storage must at all times be in full compliance with any and all local, state
and federal environmental, health and/or safety-related laws, statutes, orders,
standards, courts' decisions, ordinances, rules and regulations (as interpreted
by judicial and administrative decisions), decrees, directives, guidelines,
permits or permit conditions, currently existing and as amended, enacted, issued
or adopted in the future which are or become applicable to Tenant or all or any
portion of the Premises (collectively, the "Environmental Laws"). Tenant agrees
that any changes to the type and/or quantities of Hazardous Materials specified
in the most recent HazMat Certificate may be implemented only with the prior
written consent of Landlord, which consent may be given or withheld in
Landlord's sole discretion. Tenant shall not be entitled nor permitted to
install any tanks under, on or about the Premises for the storage of Hazardous
Materials without the express written consent of Landlord, which may be given or
withheld in Landlord's sole discretion; provided, however, that Landlord hereby
approves of Tenant constructing and maintaining outdoors immediately adjacent to
the Premises, in a location to be approved by Landlord, such approval not to be
unreasonably withheld, an approximately 1000-gallon diesel fuel above-ground
storage tank for fueling of Tenant's emergency generator, such tank to be
constructed, maintained and used strictly in accordance with all terms and
provisions of this lease and in compliance with all applicable Environmental
Laws. Landlord shall have the right at all times during the Term of this Lease
to (i) inspect the Premises, (ii) conduct tests and investigations to determine
whether Tenant is in compliance with the provisions of this Section 27 or to
determine if Hazardous Materials are present in, on or about the Project, and
(iii) request lists of all Hazardous Materials used, stored or otherwise located
on, under or about any portion of the Premises and/or the Common Areas, The cost
of all such inspections, tests and investigations shall be borne by Tenant, if
Landlord reasonably determines that Tenant or any of Tenant's Representatives
are directly or indirectly responsible in any manner for any contamination
revealed by such inspections, tests and investigations. The aforementioned
rights granted herein to Landlord and its representatives shall not create (a) a
duty on Landlord's part to inspect, test, investigate, monitor or otherwise
observe the Premises or the activities of Tenant and Tenant's Representatives
with respect to Hazardous Materials, including without limitation, Tenant's
operation, use and any remediation related thereto, or (b) liability on the part
of Landlord and its representatives for Tenant's use, storage, disposal or
remediation of Hazardous Materials, it being understood that Tenant shall be
solely responsible for all liability in connection therewith.

        27.4 TENANT'S ENVIRONMENTAL OBLIGATIONS: Tenant shall give to Landlord
immediate verbal and follow-up written notice of any spills, releases,
discharges, disposals, emissions, migrations, removals or transportation of
Hazardous Materials on, under or about any portion of the Premises or in any
Common Areas; provided that Tenant has actual, implied or constructive knowledge
of such event(s). Tenant, at its sole cost and expense, covenants and warrants
to promptly investigate, clean up, remove, restore and otherwise remediate
(including, without limitation, preparation of any feasibility studies or
reports and the performance of any and all closures) any spill, release,
discharge, disposal, emission, migration or transportation of Hazardous
Materials arising from or related to the intentional or negligent acts or
omissions of Tenant or Tenant's Representatives such that the affected portions
of the Project and any adjacent property are returned to the condition existing
prior to the appearance of such Hazardous Materials. Any such investigation,
clean up, removal, restoration and other remediation shall only be performed
after Tenant has obtained Landlord's prior written consent, which consent shall
not be unreasonably withheld so long as such actions would not potentially have
a material adverse long-term or short-term effect on any portion of the Project.
Notwithstanding the foregoing, Tenant shall be entitled to respond immediately
to an emergency without first obtaining Landlord's prior written consent.
Tenant, at its sole cost and expense, shall conduct and perform, or cause to be
conducted and performed, all closures as required by any Environmental Laws or
any agencies or other governmental authorities having jurisdiction thereof. If
Tenant fails to so promptly investigate, clean up, remove, restore, provide
closure or otherwise so remediate, Landlord may, but without obligation to do
so, take any and all steps necessary to rectify the same and Tenant shall
promptly reimburse Landlord, upon demand, for all costs and expenses to Landlord
of performing investigation, clean up, removal, restoration, closure and
remediation work. All such work undertaken by Tenant, as required herein, shall
be performed in such a manner so as to enable Landlord to make full economic use
of the Premises and the other portions of the Project after the satisfactory
completion of such work.

        27.5 ENVIRONMENTAL INDEMNITY: In addition to Tenants obligations as set
forth hereinabove, Tenant agrees to, and shall, protect, indemnify, defend (with
counsel reasonably acceptable to Landlord) and hold Landlord and the other
Indemnitees harmless from and against any and all Claims (including, without
limitation, diminution in value of any portion of the Premises or the Project,
damages for the loss of or restriction an the use of rentable or usable space,
and from any adverse impact of Landlord's marketing of any space within the
Project) arising at any time during or after the Term of this Lease in
connection with or related to, directly or indirectly, the use, presence,
transportation, storage, disposal, migration, removal, spill, release or
discharge of Hazardous Materials on, in or about any portion of the Project as a
result (directly or indirectly) of the intentional or negligent acts or
omissions of Tenant or any of Tenant's Representatives. Neither the written
consent of Landlord to the presence, use or storage of Hazardous Materials in,
on, under or about any portion of the Project nor the strict compliance by
Tenant with all Environmental Laws shall excuse


                                       17
<PAGE>   31

Tenant from its obligations of indemnification pursuant hereto. Tenant shall not
be relieved of its indemnification obligations under the provisions of this
Section 27.5 due to Landlord's status as either an "owner" or "operator" under
any Environmental Laws.

        27.6 SURVIVAL: Tenant's obligations and liabilities pursuant to the
provisions of this Section 27 shall survive the expiration or earlier

responsibility, or for any reason be liable to Tenant, for any direct or
indirect injury to or interference with Tenant's business arising from the
Renovations, nor shall Tenant be entitled to any compensation or damages from
Landlord for loss of the use of the whole or any part of the Premises or of

commercially reasonable efforts to minimize interference with Tenant's use of
the Premises during such renovations.

or the exterior of the Premises shall be subject to Landlord's prior written
approval and shall be subject to and in compliance with all applicable Laws,

repair any damage or defacement, including without limitation, discoloration
caused by such installation or removal. Landlord shall have the right, at its
option, to deduct from the Security Deposit such sums as are reasonably
necessary to remove such signs and make any repairs necessitated by such

flashing or moving sign(s) or (b) sign(s) which are likely to interfere with the
visibility of any sign, canopy, advertising matter, or decoration of any land of
any other business or occupant of the Building or the other portions of the

exterior signage planned by Tenant is subject to the prior written approval by
Landlord and approval by the City of San Jose or the applicable governmental
agency. Any approved exterior signage must be installed by a State of California
licensed contractor that adequately meets Landlord's bonding and insurance
requirements. Landlord's consent to Tenant's exterior signage consistent with
Landlord's signage program for the Project and meeting the foregoing

interest together with an address for receiving Notice, and shall offer such
beneficiary or mortgagee a reasonable opportunity to cure the default, including
time to obtain possession of the Premises by power of sale or a judicial
foreclosure, if such should prove necessary to effect a cure. If such default
cannot be cured within such time period, then such additional time as may be
necessary will be given to such beneficiary or mortgagee to effect such cure so
long as such beneficiary or mortgagee has commenced the cure within the original
time period and thereafter diligently pursues such cure to completion, in which
event this Lease shall not be terminated while such cure is being diligently
pursued. Tenant agrees that each lender to whom this tease has teen assigned by
landlord is an express third party beneficiary hereof. Tenant shall not make any
prepayment of Rent more than one (1) month in advance without the prior written
consent of each such lender, except if Tenant is required to make quarterly
payments of Rent in advance pursuant to the provisions of Section 8 above.
Tenant waives the collection of any deposit from such lender(s) or any purchaser
at a foreclosure sale of such lender(s)' deed of trust unless the lender(s) or
such purchaser shall have actually received and not refunded the deposit. Tenant
agrees to make all payments under this Lease to the lender with the most senior
encumbrance upon receiving a direction, in writing, to pay said amounts to such
lender. Tenant shall comply with such written direction to pay without
determining whether an event of default exists under such lender's loan to
Landlord, and Landlord hereby releases Tenant from any claims for having done
so. If, in connection with obtaining financing for the Premises or any other
portion of the Project, Landlord's lender shall request reasonable
modifications) to this Lease as a condition to such financing, Tenant shall not
unreasonably withhold, delay or defer its consent thereto, provided such
modifications do not materially and adversely affect Tenant's rights hereunder
or the use, occupancy or quiet enjoyment of Tenant hereunder.

Landlord, that Tenant has undertaken a complete and independent evaluation of

evaluation, Tenant has elected to enter into this Lease and hereby assumes all
risks with respect thereto. Tenant hereby further warrants and represents to
Landlord, for the express benefit of Landlord, that in entering into this Lease,
Tenant has not relied upon any statement, fact, promise or representation
(whether express or implied, written or oral) not specifically set forth herein

other real estate broker, agent or finder who is or might be entitled to a real
estate brokerage commission or finder's fee in connection with this Lease or

or expenses arising out of claims made for a fee or commission by any real
estate broker, agent or finder in connection with the Premises and this Lease
other than Broker(s), if any, resulting from the actions of the indemnifying
party. Unless expressly agreed to in writing by Landlord and Broker(s), no real
estate brokerage commission or finder's fee shall be owed to, or otherwise
payable to, the Broker(s) for any renewals or other extensions of the initial
Term of this Lease or for any additional space leased by Tenant other than the

Simultaneously with Tenant's delivery to Landlord of this Lease and the first
month's Base Rent in accordance with the provisions of Section 3 above, Tenant
shall deliver to Landlord, as collateral for the full and faithful performance
by Tenant of all of its obligations under this Lease and for all losses and
damages Landlord may suffer as a result of any default by Tenant under this
Lease, an irrevocable and unconditional negotiable letter of credit, in the form
and containing the terms required herein, payable in the City of Foster City,
California (or in addition you may state "payable in the County of San Mateo)
running in favor of Landlord issued by a solvent nationally recognized bank with
a long term rating of BBB- or higher, under the supervision of the
Superintendent of Banks of the State of California, or a National Banking
Association, in the amount of Four Million and 00/100 Dollars ($4,000,000.00)
(the "Letter of Credit"). The Letter of Credit shall be (a) at sight and
irrevocable and unconditional, (b) maintained in effect, whether through
replacement, renewal or extension, for the entire Lease Term (the "Letter of
Credit Expiration Date") and Tenant shall deliver a new Letter of Credit or
certificate of renewal or extension to Landlord at least thirty (30) days prior
to the expiration of the Letter of Credit, without any action whatsoever on the
part of Landlord, (c) subject to the Uniform Customs and Practices for
Documentary Credits (1993-Rev) International Chamber of Commerce Publication
#500, (d) acceptable to Landlord in its sole discretion, and (e) fully
assignable by Landlord and permit partial draws. In addition to the foregoing,
the form and terms of the Letter of Credit (and the bank issuing the same) shall
be acceptable to Landlord, in Landlord's sole discretion, and shall provide,
among other things, in effect that; (1) Landlord, or its then managing agent,
shall have the right to draw down an amount up to the face amount of the Letter
of Credit upon the presentation to the issuing bank of Landlord's (or Landlord's
then managing agent's) statement that such amount is due to Landlord under the
terms and conditions of this Lease, it being understood that if Landlord or its
managing agent be a limited liability company, corporation, partnership or other
entity, then such statement shall be signed by a managing member (if a limited
liability company) an officer (if a corporation), a general partner (if a
partnership), or any authorized party (if another entity); (2) the Letter of
Credit will be honored by the issuing bank without inquiry as to the accuracy
thereof and regardless of whether the Tenant disputes the content of such
statement; and (3) in the event of a transfer of Landlord's interest in the
Building, Landlord shall transfer the Letter of Credit, in whole or in part (or
cause a substitute letter of credit to be delivered, as applicable), to the
transferee and thereupon the Landlord shall, without any further agreement
between the parties, be released by Tenant from all liability therefor, and it
is agreed that the provisions hereof shall apply to every transfer or assignment
of the whole or any portion of said Letter of Credit to a new Landlord. Tenant
hereby acknowledges and agrees that Landlord is entering into this Lease in
material reliance upon the ability of Landlord to draw upon the Letter of Credit
upon the occurrence of any default on the part of Tenant hereunder which
continues beyond any applicable notice and cure periods. Tenant further
acknowledges and agrees that if Landlord cannot draw upon the Letter of Credit
within the times and in the manner as anticipated by Landlord herein, Landlord
shall suffer irreparable damage, harm and injury. From time to time during the
Term of this Lease it is anticipated by the parties that the Letter of Credit
will need to be amended, modified and, possibly reissued. Landlord and Tenant
hereby covenant and agree to cooperate with one another to promptly effectuate
any such amendments, modifications and new issuances, including without
limitation, executing and submitting to the Issuer any and all documents or
instruments as may be reasonably required to effectuate same. Each and every
time during the Term of this Lease there is a change in the identity or address
of the parties, including without limitation, any change in the identity of
Landlord due to the sale, transfer or other conveyance by Landlord of its rights
and interests in, to and under this Lease to any other party, person or entity,
the Letter of Credit shall immediately be amended or reissued to reflect such
changes and the parties hereby agree to execute and submit to the issuer such
further applications, documents and instruments as may be necessary to
effectuate same, it is the intention of the parties that each and every
successor and assign of both Landlord and Tenant be bound by and subject to the
terms and provisions of this Section 35. Landlord may, at any time and without
notice to Tenant and without first obtaining Tenant's consent thereto, assign
all or any portion of its Interest in and to the Letter of Credit to another
party, person or entity, regardless of whether or not such assignment is
separate from or as a part of the assignment by Landlord of its rights and
interests in and to this Lease. If, as a result of any such application of all
or any part of the Letter of Credit, the amount of the Letter of Credit shall be
less than Four Million and 00/100 Dollars ($4,000,000.00), Tenant shall within
five (5) days thereafter provide Landlord with additional letter(s) of credit in
an amount equal to the deficiency (or a replacement letter of credit in the
total amount of Four Million and 00/100 Dollars ($4,000,000.00) and each such
additional (or replacement) letter of credit shall comply with all of the
provisions of this Section 35, and if Tenant fails to do so, notwithstanding
anything to the contrary contained in Section 18 (reference the Tenant Default
Section of the Lease) hereof, the same shall constitute an incurable default by
Tenant. Tenant further covenants and warrants that it will neither assign nor
encumber the Letter of Credit or any part thereof and that neither Landlord nor
its successors or assigns will be bound by any such assignment, encumbrance,
attempted assignment or attempted encumbrance. Without limiting the generality
of the foregoing, if the Letter of Credit expires earlier than the Letter of
Credit Expiration Date, Landlord will accept a renewal thereof or substitute
letter of credit (such renewal or


                                       20
<PAGE>   34
substitute letter of credit to be In effect not later than thirty (30) days
prior to the expiration thereof), which shall be irrevocable and automatically
renewable as above provided through the Letter of Credit Expiration Date upon
the same terms as the expiring letter of credit or such other terms as may be
acceptable to Landlord in its sole discretion. However, if the Letter of Credit
is not timely renewed or a substitute letter of credit is not timely received,
or if Tenant fails to maintain the Letter of Credit in the amount and terms set
forth in this Section 35, Landlord shall have the right to present such Letter
of Credit to the bank in accordance with the terms of this Section 35, and the
entire sum evidenced thereby shall be paid to and held by Landlord as collateral
for performance of all of Tenant's obligations under this Lease and for all
losses and damages Landlord may suffer as a result of any default by Tenant
under this Lease. If there shall occur a default under this Lease as set forth
in Section 18 (reference Tenant Default Section of the Lease) of this Lease,
Landlord may, but without obligation to do so, draw upon the Letter of Credit,
in part or in whole, to cure any default of Tenant and/or to compensate Landlord
for any and all damages of any kind or nature sustained or which may be
sustained by Landlord resulting from Tenant's default. Tenant agrees not to
interfere in any way with payment to Landlord of the proceeds of the Letter of
Credit, either prior to or following a "draw" by Landlord of any portion of the
Letter of Credit, regardless of whether any dispute exists between Tenant and
Landlord as to landlord's right to draw from the Letter of Credit. No condition
or term of this Lease shall be deemed to render the Letter of Credit conditional
to justify the issuer of the Letter of Credit in failing to honor a drawing upon
such Letter of Credit in a timely manner. Landlord and Tenant acknowledge and
agree that in no event or circumstance shall the Letter of Credit or any renewal
thereof or substitute therefor be (i) deemed to be or treated as a "security
deposit" within the meaning of California Civil Code Section 1950.7 (as
supplemented, amended, replaced and substituted from time to time), (ii) subject
to the terms of such Section 1950.7 (as supplemented, amended, replaced and
substituted from time to time), or (iii) intended to serve as a "security
deposit" within the meaning of such Section 1950.7 (as supplemented, amended,
replaced and substituted from time to time). The parties hereto recite that with
respect to the Letter of Credit, (x) the Letter of Credit is not intended to
serve as a security deposit and such Section 1950.7 (as supplemented, amended,
replaced and substituted from time to time), and any and all other laws, rules
and regulations applicable to security deposits in the commercial context
("Security Deposit Laws") shall have no applicability or relevancy to the Letter
of Credit and (y) Tenant waives any and all rights, duties and obligations it
may now or, in the future, will have relating to or arising from the Security
Deposit Laws. Notwithstanding the above, such Letter of Credit shall be subject
to termination, however in no event earlier than the end of the thirty-sixth
(36th) month of the Lease, upon Tenant achieving a tangible net worth of One
Hundred Million and 00/100 Dollars ($100,000,000.00) and upon Tenant achieving a
net profit of at least Five Million and 00/100 Dollars ($5,000,000.00) for two
(2) consecutive quarters. However, such Letter of Credit may be reduced to
$2,000,000.00 if Tenant achieves and maintains a tangible net worth of
$100,000,000.00 and achieves a net profit of at least $5,000,000.00 for two (2)
consecutive quarters at any point prior to the end of the thirty sixth (36th)
month of the Lease Term so long as Tenant maintains such net worth through the
end of the thirty sixth (36th) month of the Lease Term. For purposes herein, the
net worth measurement shall not include non-cash charges such as deferred
compensation and acquisition charges.

36.     CAFETERIA

So long as Landlord shall maintain and operate in the Park a cafeteria for the
use of the tenants of the Park and their employees and invitees, Tenant and its
employees and invitees shall have the right, in common with the other tenants of
the Park and their employees and invitees, to use the same during its normal
hours of operation.

        IN WITNESS WHEREOF, this Lease is executed by the parties as of the
Lease Date referenced on Page 1 of this Lease.

additional plans, drawings, specifications and finish details as Landlord may
reasonably request to enable Landlord's architects and engineers, as applicable,
to prepare mechanical, electrical and plumbing plans and to prepare the Final
Drawings, including, but not limited to, a final telephone layout and special
electrical connections, if any, as such plans, drawings, specifications and
details are made available, but not later than thirty (30) days after the
Initial Plans are prepared and delivered to Tenant. All plans, drawings,
specifications and other details describing the Work which have been, or are
hereafter, furnished by or on behalf of Tenant shall be subject to Landlord's
approval, which approval shall not be unreasonably withheld. Landlord shall not
be deemed to have acted unreasonably if it withholds its approval of any plans,
specifications, drawings or other details or of any Change Request (hereafter
defined in Section 11 below) because, in Landlord's reasonable opinion, the work
as described in any such item, or any Change Request, as the case may be: (a) is
likely to adversely affect Building systems, the structure of the Building or
the safety of the Building or its occupants; (b) might impair Landlord's ability
to furnish services to Tenant (unless Tenant waives such requirement or pays for
the increased cost thereof) or other tenants in the Building; (c) would increase
the cost of operating the Building or the Park (unless Tenant pays the increased
cost thereof); (d) would violate any applicable governmental, administrative
body's or agencies' laws, rules, regulations, ordinances, codes or similar
requirements (or interpretations thereof); (e) contains or uses Hazardous
Materials in violation of law; (f) would adversely affect the appearance of the
Building or the Park; (g) might adversely affect another tenant's premises or
such other tenant's use and enjoyment of such premises; (h) is prohibited by any
ground lease affecting the Building, the Lot and/or the Park, any Recorded
Matters or any mortgage, trust deed or other instrument encumbering the
Building, the Lot and/or the Park; (1) is likely to be substantially delayed
because of unavailability or shortage of labor or materials necessary to perform
such work (beyond the current state of the materials and labor market) or the
difficult or unusual nature of such work; (j) is not, at a minimum, in
accordance with Landlord's Building Standards (defined below); or (k) would
increase the Tenant Improvement Costs (defined in Section 9 below) by more than
ten percent (10%) from the cost originally estimated and anticipated by the
parties unless Tenant agrees to pay for such increased cost to the extent it
exceeds the Allowance. The foregoing reasons, however, shall not be the only
reasons for which Landlord may reasonably withhold its approval, whether or not
such other reasons are similar or dissimilar to the foregoing. Neither the
approval by Landlord of the Work or the Initial Plans or any other plans,
specifications, drawings or other items associated with the Work nor Landlord's
performance, supervision or monitoring of the Work shall constitute any warranty
or covenant by Landlord to Tenant of the adequacy of the design for Tenants
intended use of the Premises. Tenant agrees to, and does hereby, assume full and
complete responsibility to ensure that the Work and the Approved Final Drawings
are adequate to fully meet the needs and requirements of Tenant's intended
operations of its business within the Premises and Tenant's use of the Premises.
However, Landlord shall assume responsibility for the workmanship of such work.

4. FINAL DRAWINGS AND APPROVED FINAL DRAWINGS. If necessary for the performance
of the Work, and to the extent not already included as part of the Initial Plans
attached hereto, Landlord shall prepare or cause to be prepared final working
drawings and specifications for the Work (the "Final Drawings") based on and
consistent with the Initial Plans and the other plans, specifications, drawings,
finish details or other information furnished by Tenant or Tenant's
Representatives to Landlord and approved by Landlord pursuant to Section 3
above. Tenant shall cooperate diligently with Landlord and Landlord's architect,
engineer and other representatives and Tenant shall furnish within five (5)
business days after any request therefor, all information required by Landlord
or Landlord's architect, engineer or other representatives for completion of the
Final Drawings. So long as the Final Drawings are substantially consistent with
the Initial Plans and all other information provided by Tenant and its
Representatives, Tenant shall approve the Final Drawings within five (5)
business days after receipt of same from Landlord. If Tenant reasonably
disapproves of any matters included in the Final Drawings because such items are
not substantially consistent with the Initial Plans and all other information
provided by Tenant and its Representatives, Tenant shall, within the
aforementioned five (5) business day period, deliver to Landlord written notice
of its disapproval and Tenant shall specify in such written notice, in
sufficient detail as Landlord may reasonably require, the matters disapproved,
the reasons for such disapproval, and the specific changes or revisions
necessary to be made to the Final Drawings to cause such drawings to
substantially conform to the Initial Plans. Any additional costs associated with
such requested changes or revisions shall be included as part of



                                       1
<PAGE>   37
the Tenant Improvement Costs (defined below). The foregoing procedure shall be
followed by the parties until the Final Drawings are acceptable to both Landlord
and Tenant. Landlord and Tenant shall indicate their approval of the Final
Drawings by initialing each sheet of the Final Drawings and delivering to one
another a true and complete copy of such initialed Final Drawings (the "Approved
Final Drawings"). A true and complete copy of the Approved Final Drawings shall
be attached to the Lease as Exhibit B-1 and shall be made a part thereof. Any
changes or revisions to the Approved Final Drawings requested by Tenant must
first be approved by Landlord, which approval shall not be unreasonably
withheld, subject to the provisions of Section 3 above, If Landlord approves
such requested changes or revisions, Landlord shall cause the Approved Final
Drawings to be revised accordingly and Landlord and Tenant shall initial each
sheet of the Approved Final Drawings as revised and replace and attach a true
and complete copy thereof to the Lease as Exhibit B-1. Landlord and Tenant
hereby covenant to each other to cooperate with each other and to act reasonably
in the preparation and approval of the final Drawings and the Approved Final
Drawings.

5. PERFORMANCE OF WORK. As soon as practicable after Tenant and Landlord initial
and attach to the Lease as EXHIBIT B-1 a true and complete copy of the Approved
Final Drawings, Landlord shall submit the Approved Final Drawings to the
governmental authorities having rights of approval over the Work and shall apply
for the necessary approvals and building permits. Subject to the satisfaction of
all conditions precedent and subsequent to its obligations under this EXHIBIT B,
and further subject to the provisions of Section 10 hereof, as soon as
practicable after Landlord or its representatives have received all necessary
approvals and building permits, Landlord will put the Approved Final Drawings
out for bid to at least three (3) licensed, bonded and insured mutually
acceptable general contractors. The Tenant Improvements shall be constructed by
a general contractor selected by Landlord (the "General Contractor"). In lieu of
the foregoing, Tenant may agree to negotiate with one general contractor and
such contractor shall bid all trades to at least three (3) mutually approved
subcontractors. Landlord shall commence construction, or cause the commencement
of construction by the General Contractor, of the Tenant Improvements, as soon
as practicable after selection of the General Contractor. Except as hereinafter
expressly provided to the contrary, Landlord shall cause the performance of the
Work using (except as may be stated or otherwise shown in the Approved Final
Drawings) building standard materials, quantities and procedures then in use by
Landlord ("Building Standards"). Tenant shall be permitted to receive copies of
all bids and the schedule of values.

6. SUBSTANTIAL COMPLETION. Landlord and Tenant shall cause the General
Contractor to Substantially Complete (defined below) the Tenant Improvements in
accordance with the Approved Final Drawings by the Commencement Date of the
Lease as set forth in Section 2 of the Lease (the "Completion Date"), subject to
delays due to (a) acts or events beyond its control including, but not limited
to, acts of God, earthquakes, strikes, lockouts, boycotts, casualties,
discontinuance of any utility or other service required for performance of the
Work, moratoriums, governmental agencies, delays on the part of governmental
agencies and weather, (b) the lack of availability or shortage of specialized
materials used in the construction of the Tenant Improvements, (c) any matters
beyond the control of Landlord, the General Contractor or any subcontractors,
(d) any changes required by the fire department, building and/or planning
department, building inspectors or any other agency having jurisdiction over the
Building, the Work and/or the Tenant Improvements (except to the extent such
changes are Tenant Delays, as defined in Section 7 below) (the events and
matters set forth in Subsections (a), (b), (c) and (d) are collectively referred
to as "Force Majeure Delays"), or (e) any Tenant Delays (defined in Section 7
below). The Tenant Improvements shall be deemed substantially complete on the
date that (i) the General Contractor issues to Landlord a notice of substantial
completion stating that the Tenant Improvements and all work required to be done
by Landlord are complete, including, but not limited to, the submetering and the
lobby, or (ii) the date that the building officials of the applicable
governmental agency(s) issues its final approval of the construction of the

occupancy of the Premises for the conduct of business, whichever first occurs,
provided that in any case the Building systems serving the Premises are
operational to the extent necessary for the conduct of Tenant's business
("Substantial Completion", or "Substantially Completed", or "Substantially
Complete"). Tenant hereby acknowledges and agrees that the term "Substantial
Completion" of the Tenant Improvements as used herein will not include the
completion of any work associated with Tenant's Installations, including without
limitation, Tenant's high-pile storage requirements, Tenant's racking systems,
and work related to any requirements of governmental and regulatory agencies

Substantially Completed on or before the scheduled Completion Date, (i) Landlord
agrees to use reasonable efforts to Substantially Complete the Work as soon as
practicable thereafter, (ii) the Lease shall remain in full force and effect,
(iii) Landlord shall not be deemed to be in breach or default of the Lease or
this EXHIBIT B as a result thereof and Landlord shall have no liability to
Tenant as a result of any delay in occupancy (whether for damages, abatement of
all or any portion of the Rent, or otherwise), and (iv) except in the event of
any Tenant Delays, which will not affect the Commencement Date but will extend
the Completion Date without any penalty or liability to Landlord, and
notwithstanding anything to the contrary contained in the Lease, the
Commencement Date and the Expiration Date of the term of the Lease (as defined
in Section 2 of the Lease) shall be extended commensurately by the amount of
time attributable to such Force Majeure Delays, and Landlord and Tenant shall
execute a written amendment to the Lease evidencing such extensions of time,
substantially in the form of Exhibit F to the Lease. Subject to the provisions
of Section 10.2 of the Lease, the Tenant Improvements shall belong to Landlord
and shall be deemed to be incorporated into the Premises for all purposes of the
Lease, unless Landlord, in writing, indicates otherwise to Tenant provided,
however, Tenant shall be entitled to the tax depredation benefits accruing
thereto during the term of the Lease to the extent of Tenant's cost therein.

7. TENANT DELAYS. There shall be no extension of the scheduled Commencement Date
or Expiration Date of the term of the Lease (as otherwise permissibly extended
in accordance with the provisions of Section 6 above) if the Work has not been
Substantially Completed by the scheduled Commencement Date due to any delay
attributable to Tenant and/or any of Tenant's Representatives or Tenant's
intended use of the Premises (collectively, "Tenant Delays"), including, but not
limited to, any of the following described events or occurrences that delay the
scheduled Commencement Date: (a) delays related to changes made or requested by
Tenant to the Work and/or the Approved Final Drawings; (b) the failure of Tenant
to furnish all or any plans, drawings, specifications, finish details or other
information required under Sections 3 and 4 above; (c) the failure of Tenant to
comply with the requirements of Section 10 below; (d) Tenant's requirements for
special work or materials, finishes, or installations other than the Building
Standards (unless such materials are regularly used in construction) or Tenant's
requirements for special construction or phasing (and Tenant is so notified by
Landlord that such will delay the scheduled Commencement Date); (e) any changes
required by the fire department, building or planning department, building
inspectors or any other agency having jurisdiction over the Building, the Work
and/or the Tenant Improvements if such changes are directly attributable to
Tenant's use or Tenant's specialized tenant improvements; (f) the completion of
any work associated with Tenant's Installations, including without limitation,
Tenant's high-pile storage requirements, Tenant's racking systems, and work



                                       2
<PAGE>   38
related to any requirements of governmental and regulatory agencies with respect
to any of Tenant's Installations; (g) the performance of any additional work
pursuant to a Change Request that is requested by Tenant; (h) the performance of
work in or about the Premises by any person, firm or corporation employed by or

to the Approved Final Drawings. Any delays in the construction of the Tenant
Improvements due to any of the events described above, shall in no way extend or
affect the date on which Tenant is required to commence paying Rent under the
terms of the Lease. It is the intention of the parties that all of such delays
will be considered Tenant Delays for which Tenant shall be wholly and completely
responsible for any and all consequences related to such delays, including,
without limitation, any costs and expenses attributable to increases in labor or
materials.

research and development buildings. The Tenant Improvement Allowance shall be
the maximum contribution by Landlord for the Tenant Improvement Costs and shall
be subject to the provisions of Section 10 below.

threaten to cause any such disharmony or interference, including, without
limitation, labor disharmony, and Tenant fails to immediately institute and
maintain corrective actions as directed by Landlord, then Landlord may revoke
such license upon twenty-four (24) hours' prior written notice to Tenant.

Landlord for such other Building services at Landlord's standard rates then in
effect.

                                   ADDENDUM 1
                         OPTION TO EXTEND THE LEASE TERM

This Addendum 1 ("Addendum 1") is incorporated as a part of that certain Lease
Agreement dated May 15, 2000 (the "Lease"), by and between NEW FOCUS, INC., a
California corporation ("Tenant"), and LINCOLN-RECP HELLYER OPCO, L.L.C., a
Delaware limited liability company ("Landlord"), for the leasing of those
certain premises located at 4747 Hellyer Avenue, San Jose, California as more
particularly described in Exhibit A to the Lease (the "Premises"). Any
capitalized terms used herein and not otherwise defined herein shall have the
meaning ascribed to such terms as set forth in the Lease.

1. GRANT OF EXTENSION OPTION. Subject to the provisions, limitations and
conditions set forth in Paragraph 5 below, Tenant shall have an Option
("Option") to extend the initial term of the Lease for five (5) years, (the
"Extended Term").

2. TENANT'S OPTION NOTICE. Tenant shall have the right to deliver written notice
to Landlord of its intent to exercise this Option (the "Option Notice"). If
Landlord does not receive the Option Notice from Tenant on a date which is
neither more than three hundred sixty-five (365) days nor less than two hundred
seventy (270) days prior to the end of the initial term of the Lease, all rights
under this Option shall automatically terminate and shall be of no further force
or effect. Upon the proper exercise of this Option, subject to the provisions,
limitations and conditions set forth in Paragraph 5 below, the initial term of
the Lease shall be extended for the Extended Term.

3. ESTABLISHING THE INITIAL MONTHLY BASE RENT FOR THE EXTENDED TERM.

        (a) The initial monthly Base Rent for the Extended Term shall be the
then current market rent for the highest and best use for similar space within
the competitive market area of the Premises (the "Fair Rental Value"). "Fair
Rental Value" of the Premises means the current market rental value of the
Premises as of the commencement of the Extended Term, taking into consideration
all relevant factors, including length of term, the uses permitted under the
Lease, the quality, size, design and location of the Premises, including the
condition and value of existing tenant improvements, and the monthly base rent
paid by tenants for premises comparable to the Premises, and located within the
competitive market area of the Premises, as reasonably determined by Landlord.

        (b) Neither Landlord nor Tenant shall have the right to have a court or
any other third party entity establish the Fair Rental Value. If Landlord and
Tenant are unable to agree on the Fair Rental Value for the Extended Term within
ten (10) days of receipt by Landlord of the Option Notice, such Base Rent shall
be determined by appraisal in the manner provided in subsection (c) below.

        (c) If Landlord and Tenant are unable to agree upon the amount of Base
Rent payable during the Extended Term, as provided above, they each shall, not
later than ten (10) days after the end of the period for attempting to agree
upon Base Rent, appoint an independent broker who shall have at least ten (10)
years' experience in the commercial real estate market in which the Premises is
located and shall be familiar with the valuation of comparable property in such
area and otherwise qualified to act as an expert witness over objection to give
opinion testimony addressed to the issue in a court of competent jurisdiction.
Within said ten (10) day period, each party shall notify the other party in
writing of the name, address, telephone number and qualifications of its broker
so appointed. If either party shall fail to notify the other party of its named
broker within said ten (10) day period, the determination of Base Rent by the
single broker appointed shall be conclusive and binding upon both Landlord and
Tenant.

                (i) The brokers appointed pursuant to this subsection (c) shall
determine the "Fair Rental Value" for the Premises as of the date of calculation
thereof.

                (ii) The brokers shall, not later than two (2) months prior to
the expiration of the Term, report in writing to the party appointing him/her
their opinion as to the Fair Rental Value. Each party shall, promptly upon
receipt of the valuation report from its broker, provide the other party with a
copy thereof. Not later than one and one-half (1 1/2) months prior to the
expiration of the Term, Landlord and Tenant shall meet at such times as they
shall mutually agree and endeavor in good faith to agree upon the Base Rent
based upon the reports of the brokers. If Landlord and Tenant are unable to
agree on the Base Rent within the time specified above, the brokers shall
appoint a third broker, qualified as aforesaid, who shall, not later than one
(1) month prior to the expiration of the Term, determine the Fair Rental Value
on the basis of the two valuation reports previously prepared and consultation
with such brokers and/or other experts and competent authorities as such third
broker shall deem relevant or appropriate in his/her discretion. So long as it
is not inconsistent with any of the express provisions of this Lease and is not
arbitrary and capricious, the written report and determination of Fair Rental
Value by the third broker shall be accepted by Landlord and Tenant as the Base
Rent, which determination shall be final and binding and enforceable in a court
of competent jurisdiction with the same force and effect as if the same were a
judgment duly entered by such court. In the event that the two originally
appointed brokers cannot for any reason agree on a third broker, then either
Landlord or Tenant, on behalf of both, may request appointment of such third
broker by the then Chief Judge of the United States District Court having
jurisdiction over the Premises, and neither party shall raise any question as to
such Judge's full power and jurisdiction to entertain the application for and
make such appointment hereunder.

                (iii) In the use of brokers hereunder, each party shall pay the
fees and expenses of its own broker and shall share equally the fees and
expenses of any third broker appointed hereunder.

        (d) Upon determination of the initial monthly Base Rent for the Extended
Term pursuant to the terms outlined above, Landlord and Tenant shall immediately
execute an amendment to the Lease. Such amendment shall set forth among other
things, the initial monthly Base Rent for the Extended Term. Tenant shall have
no other right to further extend the term of the Lease under this Addendum 1
unless Landlord and Tenant otherwise agree in writing. In no event shall the
monthly Base Rent for any period of the Extended Term be less than the highest
monthly Base Rent charged during the initial term of the Lease. Upon
determination of the initial monthly Base Rent for the Extended Term in
accordance with the terms outlined above, Landlord and Tenant shall immediately
execute, at Landlord's sole option, either the standard lease agreement then in
use by Landlord, or an amendment to this Lease. Such new lease



                                       1
<PAGE>   48

agreement or amendment, as the case may be, shall set forth among other things,
the initial monthly Base Rent for the Extended Term and the actual commencement
date and expiration date of the Extended Term. Tenant shall have no other right
to extend the term of the Lease under this Addendum 1 unless Landlord and Tenant
otherwise agree in writing.

4. CONDITION OF PREMISES AND BROKERAGE COMMISSIONS FOR THE EXTENDED TERM. If
Tenant timely and properly exercises this Option, in strict accordance with the
terms contained herein: (1) Tenant shall accept the Premises in its then "As-Is"
condition and, accordingly, Landlord shall not be required to perform any
additional improvements to the Premises; and (2) Tenant hereby agrees that it
will be solely responsible for any and all brokerage commissions and finder's
fees payable to any broker now or hereafter procured or hired by Tenant or who
otherwise claims a commission based on any act or statement of Tenant ("Tenant's
Broker") in connection with the Option. Tenant hereby further agrees that
Landlord shall in no event or circumstance be responsible for the payment of any
such commissions and fees to Tenant's Broker.

5. LIMITATIONS ON, AND CONDITIONS TO EXTENSION OPTION. This Option is personal
to Tenant and may not be assigned, voluntarily or involuntarily, separate from
or as part of the Lease, except for permitted transfers to Affiliates. At
Landlord's option, all rights of Tenant under this Option shall terminate and be
of no force or effect if any of the following individual events occur or any
combination thereof occur: (1) Tenant is in default of any provision of the
Lease on the date Landlord receives the Option Notice; and/or (2) Tenant has
assigned its rights and obligations under all or part of the Lease or Tenant has
subleased all or part of the Premises; and/or (3) Tenant's financial condition
is unacceptable to Landlord at the time the Option Notice is delivered to
Landlord; and/or (4) Tenant has failed to exercise properly this Option in a
timely manner in strict accordance with the provisions of this Addendum 1;
and/or (5) Tenant no longer has possession of all or any part of the Premises
under the Lease, or if the Lease has been terminated earlier, pursuant to the
terms and provisions of the Lease.

6. TIME IS OF THE ESSENCE. Time is of the essence with respect to each and every
time period described in this Addendum 1.

                                   ADDENDUM 2
                              RIGHT OF FIRST OFFER

This Addendum 2 ("Addendum 2") is incorporated as a part of that certain Lease
Agreement dated May 15, 2000 (the "Lease"), by and between NEW FOCUS, INC., a
California corporation ("Tenant"), and LINCOLN-RECP HELLYER OPCO, L.L.C., a
Delaware limited liability company ("Landlord") for the leasing of those certain
premises located at 4747 Hellyer Avenue, San Jose, California as more
particularly described in Exhibit A to the Lease (the "Premises"). Any
capitalized terms used herein and not otherwise defined herein shall have the
meaning ascribed to such terms as set forth in the Lease.

During only the initial term of the Lease, Tenant shall have a one-time (not
continuing) right to make a first offer to lease (the "Right of First Offer")
from Landlord all of the contiguous 25,000 square foot premises Immediately
adjoining the Premises, as such expansion space is specified in Exhibit H
attached hereto and made a part hereof (the "Expansion Space"). Tenant's Right
of First Offer, as granted herein, is subject to the following conditions:

        i. The Right of First Offer for the Expansion Space shall be subject to
the rights and options of the existing tenant of the Expansion Space (together
with their successors and assigns) presently occupying said Expansion Space
pursuant to the terms and provisions of such existing tenant's lease, as such
lease may be later modified, amended or extended;

        ii. The Right of First Offer for the Expansion Space shall be void if
Tenant has been more than twice during the twelve (12) month period immediately
preceding the date of Landlord's Availability Notice (defined below), or at the
time of exercise of the Right of First Offer is then presently in default in the
performance of any of its obligations under the Lease beyond any applicable cure
periods; and

        iii. The Right of First Offer for the Expansion Space shall be subject
to Landlord's review and approval of Tenant's then current financial condition
[which financial condition shall be deemed to be acceptable to Landlord so long
as (a) Tenant, at the time of exercise of the Right of First Offer and for the
prior twelve month period of time prior to Tenant's exercise of this Right of
First Offer, has a tangible net worth of One Hundred Million and 00/100 Dollars
($100,000,000.00) and has achieved a net profit of at least Five Million and
00/100 Dollars ($5,000,000.00) for two (2) consecutive quarters, or (b) the
Letter of Credit shall still be in effect in the amount required by Section 35
of the Lease, and in the possession of and available for use by Landlord,
provided that the amount of such Letter of Credit shall, prior to the delivery
of possession of the Expansion Premises to Tenant, be increased such that the
proportion of the increased Letter of Credit to the prior amount of the Letter
of Credit is the same as the proportion of the area of the entire Premises,
including the Expansion Premises, to the prior area of the Premises].

Provided the foregoing conditions are satisfied when the Expansion Space becomes
available, then if the Expansion Space becomes vacant, and Landlord desires to
lease the Expansion Space, Landlord shall give Tenant written notice, by
facsimile and by mail describing the estimated date upon which Landlord can
deliver the Expansion Space to Tenant, and the terms and conditions upon which
Landlord is willing to lease the Expansion Space (a "Landlord's Availability
Notice"). Tenant shall notify Landlord within three (3) business days following
receipt of Landlord's Availability Notice of Tenant's election to lease the
Expansion Space upon all of the terms specified in the Landlord's Availability
Notice by written acceptance delivered to Landlord without any deviation in such
offered terns (an "Election Notice"). If Tenant fails to notify Landlord of
Tenant's election to lease the Expansion Space within the time specified herein,
it shall be deemed that: (a) Tenant has elected not to lease said Expansion
Space; (b) Landlord may thereafter enter into a lease agreement with a third
party for the Expansion Space; and (c) all rights under this Right of First
Offer with respect to the Expansion Space shall terminate and be of no further
force or effect. Time is of the essence herein,

If Tenant duly and timely exercises this Right of First Offer as herein provided
with respect to the Expansion Space, Tenant shall deliver to Landlord a
refundable deposit of Fifty Thousand Dollars ($50,000.00) for the Expansion
Space. The parties shall have ten (10) business days after Landlord receives the
Election Notice for the Expansion Space and the non-refundable deposit therefor
from Tenant in which to execute an amendment to the Lease setting forth the
agreed-upon terms for such Expansion Space. Upon full execution of an amendment
for the Expansion Space, the non-refundable deposit shall be credited toward the
first month's Base Rent for the Expansion Space, as agreed between the parties.

This Right of First Offer shall terminate and be of no force or effect if the
Premises are being subleased to a party other than an Affiliate or party who
occupies more than 50% of the Premises for the remaining Term of the Lease at
the time that this Right of First Offer for the Expansion Space is offered to
Tenant.

Except to an Affiliate in accordance with the provisions of Section 14.8 of the
Lease, this Right of First Offer is personal to Tenant and may not be assigned,
voluntarily or involuntarily, separate from or as a part of the Lease. If Tenant
duly and timely exercises this Right of First Offer for the Expansion Space,
Landlord and Tenant shall execute an amendment to this Lease, adding the
Expansion Space to the Premises and adjusting the Base Rent and Tenant's
proportionate share of the items set forth in Sections 6 and 7 of this Lease. If
Tenant does not elect to exercise the Right of First Offer granted herein for
the Expansion Space (or it is deemed that Tenant has not elected to exercise
this Right of First Offer due to the lapse of time or any other failure of
Tenant to strictly comply with the provisions of this Addendum 2), based upon
the material terms proposed by Landlord in the applicable Landlord's
Availability Notice, all rights of Tenant under, in or to this Right of First
Offer for the Expansion Space shall terminate and be of no further force or
effect.

                                  WITNESSETH:

        WHEREAS, the Tenant has entered into a lease dated *, 199 (the "Lease"),
whose interest is held by Landlord, covering premises (the "Premises") described
in Exhibit "A" attached hereto and incorporated herein by reference; and

        WHEREAS, the Lender has agreed to make a loan of * ($*) to the Landlord
secured by a Deed of Trust, hereinafter referred to as "mortgage" (which
mortgage also secures any future advances made by Lender); provided, however,
that said lease is subordinate to the lien of the mortgage; and

        WHEREAS, Lender has been requested by Tenant and by Landlord to enter
into a non-disturbance agreement with Tenant;

        NOW THEREFORE, in consideration of the promises and mutual covenants
hereinafter contained, the parties hereto mutually covenant and agree as
follows:

        1. The Lease and any extensions, renewals, replacements or modifications
thereof, and all of the right, title and interest of the Tenant in and to said
Premises, including but not limited to any option or right of first refusal to
purchase Premises, or any acquisition of title to the Premises by Tenant during
the term of the mortgage, are and shall be subject and subordinate to the
mortgage and to all of the terms and conditions contained herein, and to any
renewals, modifications, replacements, consolidations and extensions thereof.

        2. Lender consents to the Lease and, in the event of foreclosure of said
mortgage, or in the event Lender comes into possession or acquires title to the
premises as a result of the enforcement or foreclosure of the mortgage or
mortgage note, or as a result of any other means, Lender agrees to recognize
Tenant and further agrees that Tenant shall not be disturbed in its possession
of the Premises for any reason other than one which would entitle the Landlord
to terminate the Lease under its terms or would cause, without further action by
such Landlord, the termination of the Lease or would entitle such Landlord to
dispossess the Tenant from the Premises.

        3. Tenant agrees with Lender that if the interest of Landlord in the
Premises shall be transferred to and owned by Lender by reason of foreclosure or
other proceedings brought by it, or by any other manner, Tenant shall be bound
to Lender under all of the terms, covenants and conditions of the Lease for the
balance of the term thereof remaining and any extensions or renewals thereof
which may be affected in accordance with any option therefor in the Lease, with
the same force and effect as if Lender were the Landlord under the Lease, and
Tenant does hereby attorn to Lender as its Landlord, said attornment to be
effective and self-operative without the execution of any further instruments on
the part of any of the parties hereto immediately upon Lender succeeding to the
interest of the Landlord in the Premises. Tenant agrees, however, upon the
election of and written demand by Lender after Lender receives title to the
Premises, to promptly execute an instrument in confirmation of the foregoing
provisions, satisfactory to Lender, in which Tenant shall acknowledge such
attornment and shall set forth the terms and conditions of its tenancy.

        4. Tenant agrees with Lender that if Lender shall succeed to the
interest of Landlord under the Lease, Lender shall not be (a) liable for any
action or omission of any prior landlord under the Lease, or (b) subject to any
offsets or defenses which Tenant might have against any prior landlord, or (c)
bound by any rent or additional rent which Tenant might have paid for more than
the current month to any prior landlord, or (d) bound by any security deposit
which Tenant may have paid to any prior landlord, unless such deposit is in an
escrow fund available to Lender, or (e) bound by any amendment or modification
of the Lease made without Lender's consent, or (f) bound by any provision in the
Lease which obligates the Landlord to erect or complete any building or to
perform any construction work or to make
