         2.   Property Leased.
              
              2..1 Premises.  Landlord hereby leases to Tenant and Tenant hereby
leases  from  Landlord,  upon the terms and  conditions  herein set forth,  that
certain  building  ("Premises")  referred  to  in  Paragraph  1.4  above,  shown
cross-hatched on the site plan attached hereto as Exhibit A. In addition, Tenant
shall  have  the  following  rights  with  respect  to the  real  property  more
particularly described in the legal description attached as Exhibit B hereto (if
applicable) and outlined in red on Exhibit A ("Common Area"):  (i) the exclusive
right to use no more than the  number of parking  spaces set forth in  Paragraph
1.12 above,  as shown on Exhibit A, the  location  of which may be  redesignated
from  time to time by  Landlord;  (ii) the  nonexclusive  right to use any other
parking  spaces  within the Common Area not  allocated  for the exclusive use of
another  tenant of Landlord;  and (iii) such other rights as are  necessary  and
convenient  to Tenant's  possession of the Premises or  performance  of Tenant's
obligations  under this  Lease.  (Notwithstanding  the number of parking  spaces
designated  for  Tenant's  exclusive  use,  in the  event by reason of any rule,
regulation,   order,  law,  statute,  ordinance  or  other  requirement  of  any
governmental  or  quasi-governmental   authority  now  or  hereafter  in  effect
(collectively,  "Laws") relating to or affecting  parking on the Common Area, or
any other cause beyond Landlord's  reasonable  control,  Landlord is required to
reduce the number of parking spaces on the Common Area,  Landlord shall have the
right to  proportionately  reduce the number of parking spaces designated herein
for  Tenant's  exclusive  use.)  In  addition,   Landlord  grants  to  Tenant  a
non-exclusive  easement for  vehicular  ingress and egress in and over the paved
roadways  in the Common Area and  pedestrian  ingress and egress in and over the
Common Area.

              Landlord  reserves the right to grant to tenants of the  buildings
or improvements  which now exist or may hereafter be constructed upon the Common
Area or upon real property owned by Landlord adjacent to the Common Area, and to
the agents,  employees,  servants,  invitees,  contractors,  guests,  employees,
servants, invitees,  contractors,  guests, customers and representatives of such
tenants or to any other user authorized by Landlord,  the non-exclusive right to
use the  Common  Area for  pedestrian  and  vehicular  ingress  and  egress  and
vehicular  parking and the exclusive  right to use parking  spaces on the Common
Area  (excluding  only that  portion of the Common  Area  designated  herein for
Tenant's  exclusive  use  for  vehicular  parking).  

              2..2 Improvements.  The improvements to be constructed by Landlord
for Tenant's use in the Premises are set forth in detail on the attached Exhibit
C. The work described in Exhibit C includes any additional  improvements  to the
Premises  and/or the Common Area that may be  required  pursuant to Title 24 and
Title III of the Americans  with  Disabilities  Act of 1990,  42 U.S.C.  section
12101 et. seq., and the regulations promulgated thereunder (the "ADA") by reason
of the construction of the improvements in the Premises.

              In the event of  changes to any of the work set forth in Exhibit C
(whether  such  changes are required by any public  agency,  or by reason of any
error or  omission  in plans  because of  information  provided  to  Landlord by
Tenant,  or because  requested  in writing by Tenant and  accepted in writing by
Landlord), Tenant shall pay to Landlord Landlord's costs related to such changes
before work in regard to such changes is  commenced;  provided,  however,  in no
event shall  Landlord's  failure to demand such payment before  commencement  of
work in regard to such changes,  or Tenant's  failure to pay for the same before
commencement  of work in  regard  to such  changes  be  deemed to be a waiver of
Landlord's right to require or enforce collection of such payment for changes at
any time  thereafter.  Landlord's  costs related to the changes  shall  include,
without limitation, all architectural, contractor, and engineering expenses, and
the  cost  of all  building  and  other  permits  and  inspection  fees.  Tenant
acknowledges  that  Landlord or a person or entity  related to  Landlord  and/or
controlled  by  Landlord  may serve as  Landlord's  architect,  engineer  and/or
contractor  in  regard  to the  above-described  work  and in the  event  of any
changes,  Landlord's  costs  shall be deemed to include  architect,  engineering
and/or  contractor  expenses at the rates  charged to third  parties by Landlord
and/or  such  related  person  or entity  for such  services,  unless  otherwise
expressly provided in this Lease.

              Since any  construction  work on the  Premises by Tenant  prior to
substantial  completion  of the  work  required  of  Landlord  pursuant  to this
Paragraph  2.2  may  interfere  with  the  work  required  of  Landlord  or with
Landlord's  ability  to  obtain  a  certificate  of  occupancy  (or  equivalent)
therefor,  any  such  work by  Tenant  shall be  subject  to the  provisions  of
Paragraph 13.1 hereof,  and Landlord may in its reasonable  discretion  withhold
its consent to any such work by Tenant.

              2..3 Acceptance of Premises. By taking possession of the Premises,
Tenant  shall be  deemed  to have  accepted  the  Premises  as being in good and
sanitary order,  condition and repair and to have accepted the Premises in their
condition  existing  as of the date Tenant  takes  possession  of the  Premises,
subject to all applicable laws, covenants, conditions,  restrictions,  easements
and other matters of public record and the reasonable rules and regulations from
time  to  time  promulgated  by  Landlord  (and  non-discriminatorily   applied)
governing the use of the Premises and Common Area, and further, to have accepted
tenant improvements to be constructed by Landlord (if any) as being completed in
accordance with the plans and specifications for such improvements, subject only
to  completion  of items on  Landlord's  punch list.  Tenant  acknowledges  that
neither Landlord nor Landlord's agents have made any  representation or warranty
as to the suitability of the Premises for the conduct of Tenant's business,  the
condition of the Premises, or the use or occupancy which may be made thereof and
Tenant has  independently  investigated  and is satisfied  that the premises are
suitable for Tenant's  intended use and that the Premises meets all governmental
requirements for such intended use. In addition, except for such improvements as
may be included in Exhibit C, Landlord makes no representation or warranty as to
the compliance of the Premises or the Common Area with the  requirements  of the
ADA.

              Notwithstanding  anything to the contrary contained in this Lease,
Tenant's  acceptance of the Premises or submission of a "punchlist" shall not be
deemed  a  waiver  of  Tenant's  right  to  have  defects  in  the  improvements
constructed by Landlord pursuant to Paragraph 2.2 or in the Premises repaired at
no cost to Tenant. Tenant shall give notice to Landlord whenever any such defect
becomes  reasonably  apparent,  and Landlord  shall repair the defect as soon as
practicable.  Landlord also hereby assigns to Tenant all warranties with respect
to the Premises,  including  warranties that would reduce  Tenant's  maintenance
obligations  under this Lease,  and shall  cooperate with Tenant to enforce such
warranties. Finally,  notwithstanding anything to the contrary contained in this
Lease,  as of the  Commencement  Date,  the roof  (including  roof  screens  and
membrane),  plumbing,  electrical  (including  all  outlets),  heating  and  air
conditioning systems in the Premises shall be in good working order and repair.

         3. Term. 

              3..1  Commencement  Date.  The term of this Lease  ("Lease  Term")
shall be for the period specified in Paragraph 1.5 above, commencing on the date
set forth in Paragraph 1.6  ("Commencement  Date");  provided,  however,  in the
event any improvements to be constructed by Landlord, as set forth on Exhibit C,
are not completed by the aforesaid  Commencement  Date or are completed prior to
such  Commencement  Date, then the  Commencement  Date shall be deemed to be the
date on which the  improvements to be constructed by Landlord are  substantially
completed.  Such improvements shall be deemed to be substantially completed upon
the occurrence of the earlier of the following:

                     (a) The date on which all improvements to be constructed by
Landlord have been substantially  completed except for punch list items which do
not  prevent  Tenant  from using the  Premises  for its  intended  use,  and the
appropriate  governmental  approvals  for  occupancy of the  Premises  have been
issued; or

                     (b) The date on which all improvements to be constructed by
Landlord  would  have  been  substantially  completed  except  for such  work as
Landlord  is  required  to perform  but which is  delayed  because of any of the
following  (each,  a "Tenant  Delay"):  (i) fault or neglect of Tenant,  acts of
Tenant or Tenant's agents  (including  without  limitation delays caused by work
done on the  Premises  by  Tenant  or  Tenant's  agents  or by acts of  Tenant's
contractors or subcontractors); (ii) delays caused by change orders requested by
Tenant or required  because of any errors or  omissions  in plans  submitted  by
Tenant;  and (iii) such work as  Landlord  is  required  to  perform  but cannot
complete until Tenant performs  necessary  portions of construction  work it has
elected or is required to do; or

                     (c) The date Tenant opens for business in the Premises.

              If the improvements to be constructed by Landlord are deemed to be
substantially  completed pursuant to Paragraph 3.1(b) above, Tenant acknowledges
that the Commencement Date shall occur, and therefore Tenant's obligation to pay
Rentals  shall  commence,  earlier  than the date of actual  completion  of such
improvements.  The improvements to be constructed by Landlord shall be deemed to
be  substantially  completed one day earlier than the date of actual  completion
for each day that actual completion is delayed by reason of a Tenant Delay.

              If the  Commencement  Date is a date other than the date set forth
in Paragraph  1.6,  then the Ending Date set forth in Paragraph  1.7, the rental
adjustment  dates set  forth  in   Paragraph  1.8 and any  other  certain  dates
specified  herein shall be adjusted  accordingly.  When the  Commencement  Date.
Ending Date, rental adjustment dates, and such other dates become ascertainable,
Landlord  and  Tenant  shall  specify  the same in  writing,  in the form of the
attached Exhibit D, which writing shall be deemed incorporated herein.  Tenant's
failure to execute and deliver  the letter  attached  hereto as Exhibit D within
thirty (30) days after Tenant  receives  written  request from Landlord to do so
(subject to any legitimate  disagreement by Tenant with the terms thereof. which
both  parties  shall use  reasonable  efforts to resolve)  shall be a Default by
Tenant hereunder. The expiration of the Lease Term or sooner termination of this
Lease is referred to herein as the "Lease Termination".

              3..2 Delay of Commencement Date.  Landlord shall not be liable for
any damage or loss incurred by Tenant for Landlord's  failure for whatever cause
to deliver  possession of the Premises by any  particular  date  (including  the
Commencement  Date), nor shall this Lease be void or voidable on account of such
failure to deliver  possession of the  Premises;  provided that if Landlord does
not  deliver  possession  of the  Premises to Tenant by the date which is ninety
(90) days from the date this Lease is executed  by both  parties,  Tenant  shall
have the right to terminate this Lease by written  notice  delivered to Landlord
within five (5) days  thereafter,  and  Landlord and Tenant shall be relieved of
their respective obligations  hereunder;  provided further that said ninety (90)
day  period  shall be  extended  by the number of days work on the  Premises  is
delayed due to fault or neglect of Tenant, acts of Tenant or Tenant's agents, or
due to acts of God, labor  disputes,  strikes,  fires,  rainy or stormy weather,
acts or  failures  to act of  public  agencies,  inability  to  obtain  labor or
materials,   earthquake,  war,  insurrection,  riots  and  other  causes  beyond
Landlord's  reasonable  control,  excluding,  however,  delays  caused solely by
Landlord, its agents, employees, contractors or invitees.

              3..3 Early  Occupancy.  If Tenant takes possession of the Premises
prior to the Commencement  Date,  Tenant shall do so subject to all of the terms
and conditions hereof and shall pay the Rentals provided for herein.

              3..4 Tenant to Physically Occupy Premises.  Tenant shall, no later
than  thirty (30) days after the  Commencement  Date,  go into  actual  physical
occupancy of the Premises and open the Premises for business in accordance  with
the uses specified in Paragraph 6 below; provided, however, the date of Tenant's
physical  occupancy  of the Premises  shall in no event extend the  Commencement
Date, the Lease  Termination  date or the date the payment of Rentals  hereunder
commences. Time is of the essence.

              3..5 Option to  Extend  Lease Term.  In  consideration  for Tenant
never having been in default under this Lease,  Landlord hereby grants to Tenant
the option to extend  the Lease  Term for a period of Five (5) years  ("Extended
Term"), on the following terms and conditions:

                     (a)  Tenant  shall  give  Landlord  written  notice  of its
exercise of the option to extend the Lease Term no earlier  than two hundred ten
(210)  days nor later than one  hundred  eighty  (180) days  before the date the
Lease Term would end but for said exercise. Time is of the essence.

                     (b) Tenant may not extend the Lease Term  pursuant  to this
Paragraph  3.5 if Tenant has been in default  in the  performance  of any of the
terms and  conditions  of this Lease at any time  prior to the date of  Tenant's
notice of exercise of this option, or if Tenant shall have assigned or otherwise
transferred  its  interest  in this Lease  and/or the  Premises,  whether or not
Landlord's  consent to such  assignment or transfer has been given. If Tenant is
in default  under this Lease on the date that the Extended  Term is to commence,
then Landlord may elect to terminate this Lease notwithstanding any notice given
by Tenant of an exercise of its option to extend.

                     (c) All terms and  conditions  of this  Lease  shall  apply
during the Extended  Term,  except that the Rent for the Extended  Term shall be
determined in accordance with Paragraph 4.4.

                     (d) Once  Tenant  delivers  notice of its  exercise  of the
option to extend the Lease Term,  Tenant may not  withdraw  such  exercise  and,
subject to the  provisions of this  Paragraph  3.5, such notice shall operate to
extend the Lease Term.  Upon the  extension  of the Lease Term  pursuant to this
Paragraph  3.5,  the term "Lease  Term" as used in this Lease  shall  thereafter
include the Extended Term and the Lease Termination date shall be the expiration
date of the Extended Term.

         4. Rent.

              4..1 Rent.  Tenant  shall pay to Landlord as rent for the Premises
("Rent"), in advance, on the first day of each calendar month, commencing on the
date specified in Paragraph 1.6 and  continuing  throughout the Lease Term until
adjusted  pursuant to Paragraph  4.4 below the Rent set forth in  Paragraph  1.8
above.  Rent shall be  prorated,  based on thirty  (30) days per month,  for any
partial month during the Lease Term.  Rent shall be payable  without  deduction,
offset,  prior notice or demand in lawful money of the United States to Landlord
at the address herein  specified for purposes of notice or to such other persons
or such other places as Landlord may designate in writing.

              4..2 Late Charge.  Tenant hereby acknowledges that late payment by
Tenant to Landlord of Rent will cause  Landlord to incur costs not  contemplated
by this  Lease,  the  exact  amount  of which  will be  extremely  difficult  to
ascertain. Such costs include, but are not limited to, processing and accounting
charges,  and late charges  which may be imposed on Landlord by the terms of any
mortgage or deed of trust covering the Premises.  Accordingly,  Tenant shall pay
to Landlord, as Additional Rent (as defined in Paragraph 4.3 below), without the
necessity of prior notice or demand, a late charge equal to ten percent (10%) of
any  installment of Rent which is not received by Landlord  within ten (10) days
after the due date for such installment. The parties hereby agree that such late
charge  represents a fair and  reasonable  estimate of the costs  Landlord  will
incur by reason of late payment by Tenant.  In no event shall this provision for
a late charge be deemed to grant to Tenant a grace  period or  extension of time
within which to pay any installment of Rent or prevent  Landlord from exercising
any right or remedy  available  to Landlord  upon  Tenant's  failure to pay such
installment  of Rent  when  due,  including  without  limitation  the  right  to
terminate  this Lease.  In the event any  installment of Rent is not received by
Landlord by the  thirtieth  (30th) day after the due date for such  installment,
such  installment  shall bear interest at the annual rate set forth in Paragraph
34 below, commencing on the thirty-first (31st) day  after the due date for such
installment and continuing until such installment is paid in full.
             
              4..3 Additional Rent. All taxes,  charges,  costs and expenses and
other sums which Tenant is required to pay hereunder (together with all interest
and charges that may accrue thereon in the event of Tenant's  failure to pay the
same), and all damages,  costs and reasonable  expenses which Landlord may incur
by  reason of any  Default  by Tenant  shall be  deemed  to be  additional  rent
hereunder  ("Additional  Rent").  Additional Rent shall accrue commencing on the
Commencement  Date. In the event of nonpayment by Tenant of any Additional Rent,
Landlord shall have all the rights and remedies with respect thereto as Landlord
has for the  nonpayment of Rent.  The term "Rentals" as used in this Lease shall
mean Rent and Additional Rent.

              4..4 Cost of Living  Adjustment.  The Rent payable hereunder shall
be adjusted  pursuant to this Paragraph 4.4, at the times specified in Paragraph
1.8, and the Rent as adjusted shall be payable monthly  pursuant to the terms of
Paragraph 4.1 above until the next adjustment  under this Paragraph 4.4. As used
herein  the term  "Adjustment  Date"  shall  mean the  effective  date of a Rent
adjustment  pursuant to this Paragraph 4.4. As of each Adjustment Date, the Rent
shall be increased  to a sum equal to the product  obtained by  multiplying  the
then current Rent by a fraction,  the  numerator of which is the New Index as of
the  applicable  Adjustment  Date and the  denominator  of which is the  Initial
Index.  In the event  the New Index is not  available  on the  Adjustment  Date,
Landlord  shall notify Tenant of the adjustment as soon as the New Index becomes
available,  and Tenant shall  immediately  pay any amount that has accrued since
the Adjustment  Date. For the purposes of adjusting the Rent as provided in this
Paragraph  4.4, the  following  definitions  shall apply:  

                     (a) "Index" means the Consumer  Price Index (all items) for
All Urban  Consumers  as  published by the United  States  Department  of Labor,
Bureau of Labor Statistics, for the San Francisco, Oakland, San Jose, California
Area (1982-1984=100);

                     (b) "Initial Index" means in regard to the first adjustment
pursuant to this  Paragraph  4.4, the Index  published for the month nearest but
prior to the Commencement Date and in regard to all subsequent adjustments,  the
Index published nearest but prior to the immediately preceding Adjustment Date;

                     (c) "New Index" means the Index published nearest but prior
to the applicable Adjustment Date.

                     (d) The Cost of  Living  Adjustment  shall not be less than
Four Percent (4%) nor more than Six Percent (6%) per annual adjustment.

              If, at any time when the Rent is to be adjusted as provided above,
the Index is changed so that the base year  differs  from the base year used for
the  Initial  Index,  the  Index  shall  be  converted  in  accordance  with the
conversion factor published by the United States Department of Labor,  Bureau of
Labor  Statistics.  In the event the Index is otherwise  changed or discontinued
during the Lease Term,  the most nearly  comparable  official price index of the
United States  Government  (as determined in Landlord's  reasonable  discretion)
shall be used for computing the  adjustments to Rent. In no event shall the Rent
following any adjustment pursuant to this Paragraph 4.4 be less than the current
Rent immediately prior to the applicable Adjustment Date.

              4..5 Rent During  Extended  Term.  If Tenant  elects to extend the
Lease Term  pursuant to Paragraph 3.5 the Rent for the Extended Term shall be an
amount equal to ninety-five percent (95%) of the fair market rental value of the
Premises  in  relation  to  market  conditions  at  the  time  of the  extension
(including,  but  not  limited  to,  rental  rates  for  comparable  space  with
comparable tenant  improvements and taking into consideration any adjustments to
rent based upon direct  costs  (operating  expenses)  and taxes,  load  factors,
financing  charges,  and/or  cost of living  or other  rental  adjustments;  the
relative  strength of the tenants;  the size of the space; and any other factors
which affect market rental values at the time of  extension),  subject to annual
cost  of  living  adjustments  as  called  for in  Paragraph  4.4 of the  Lease;
provided,  that the Rent for the First  Year of the  Extended  Term  shall in no
event be lower than the Rent for the last Lease Year of the original  term.  The
Rent for the Extended Term shall be determined as follows:

                     (a) Mutual Agreement.  After timely  receipt by Landlord of
Tenant's notice of exercise of the option to extend the Lease Term, Landlord and
Tenant shall have a period of thirty (30) days in which to agree on the Rent and
any cost of living  adjustment  for the  Extended  Term.  If Landlord and Tenant
agree on said Rent  during  that  period,  they  shall  immediately  execute  an
amendment to this Lease stating the Rent and any cost of living  adjustment  for
the  Extended  Term.  If Landlord and Tenant are unable to agree on the Rent and
any cost of living adjustment for the Extended Term as aforesaid, the provisions
of Paragraph 4.4(b) shall apply.  

                     (b) Appraisal. Within five (5) days after the expiration of
the thirty (30) day period described in Paragraph  4.4(a) above,  each party, at
its cost and by giving notice to the other party,  shall appoint an M.A.I.  real
estate  appraiser with at least five (5) years  full-time  commercial  appraisal
experience  in the area in which the Premises  are located,  to appraise and set
the fair market rental value of the Premises and determine market cost of living
adjustments,  if any. If a party does not appoint an  appraiser  within five (5)
days after the other party has given  notice of the name of its  appraiser,  the
single  appraiser  appointed  shall be the sole appraiser and shall set the fair
market rental value and determine market cost of living adjustments, if any. The
cost of such  sole  appraiser  shall be borne  equally  by the  parties.  If two
appraisers are appointed by the parties as provided in this  Paragraph,  the two
appraisers  shall meet  promptly and attempt to set the fair market rental value
and determine market cost of living  adjustments,  if any. If they are unable to
agree within twenty (20) days after the last appraiser has been appointed,  then
the two appraisers  shall select a third  appraiser  meeting the  qualifications
stated in this Paragraph  4.4(b) within ten (10) days after the last day the two
appraisers  are given to set the fair market rental value and  determine  market
cost of living  adjustments,  if any.  If they are  unable to agree on the third
appraiser,  either of the parties to this Lease,  by giving ten (10) days notice
to the other party,  may apply to the presiding  judge of the Superior  Court of
Santa  Clara  County  for the  selection  of a third  appraiser  who  meets  the
qualifications  stated above.  Each of the parties shall bear one-half  (1/2) of
the cost of appointing the third  appraiser and of paying the third  appraiser's
fee.  The  third  appraiser,  however  selected,  shall be a person  who has not
previously acted in any capacity for either party. Within twenty (20) days after
the selection of the third  appraiser,  the majority of the appraisers shall set
the fair market rental value and determine market cost of living adjustments, if
any. If the majority of the  appraisers are unable to set the fair market rental
value and  determine  market  cost of living  adjustments,  if any,  within said
twenty (20) day period,  the three value  appraisals shall be added together and
the total  divided by three;  the  resulting  quotient  shall be the fair market
rental value. Ninety-five percent (95%) of said amount shall be the Rent for the
Extended Term. Provided,  however, that if any appraisal differs from the median
appraisal  by an amount  equal to more  than ten  percent  (10%) of such  median
appraisal, that appraisal shall be disregarded, and the average of the remaining
appraisals (or the remaining  appraisal)  shall be the fair market rental value.
The appraisers shall jointly  determine any market cost of living  adjustment to
be applied to said amount  during the Extended  Term. In  establishing  the fair
market rental value and market cost of living adjustments, if any, the appraiser
or appraisers shall consider the reasonable  market rental value for the highest
and best use for the Premises  (including,  but not limited to, rental rates for
comparable space with comparable tenant improvements and any adjustments to rent
based upon direct costs (operating expenses) and taxes, load factors,  financing
charges, and/or cost of living or other rental adjustments the relative strength
of the tenants;  and the size of the space);  without regard to the existence of
this Lease but taking into consideration the absolute nature of this Lease.

5. Security Deposit

         5.  Security  Deposit.  Concurrently  with  Tenant's  execution of this
Lease,  Tenant  shall  deposit  with  Landlord  a  security  deposit  ("Security
Deposit") in the amount set forth in Paragraph 1.10 above.  The Security Deposit
shall be held by Landlord as security for the faithful  performance by Tenant of
each and every term,  covenant and condition of this Lease applicable to Tenant,
and not as  prepayment  of Rent.  If  Tenant  shall at any time  fail to keep or
perform any term,  covenant or  condition  of this Lease  applicable  to Tenant,
including,  without  limitation,  the  payment of  Rentals  or those  provisions
requiring  Tenant  to  repair  damage  to the  Premises  caused  by Tenant or to
surrender the Premises in the condition required pursuant to Paragraph 35 below,
Landlord  may, but shall not be  obligated  to and without  waiving or releasing
Tenant from any obligation  under this Lease,  use, apply or retain the whole or
any part of the Security  Deposit  reasonably  necessary  for the payment of any
amount which Landlord may spend by reason of Tenant's default or as necessary to
compensate  Landlord for any loss or damage which  Landlord may suffer by reason
of Tenant's  default.  In the event  Landlord uses or applies any portion of the
Security  Deposit,  Tenant  shall,  within five (5) business  days after written
demand by Landlord,  remit to Landlord  sufficient funds to restore the Security
Deposit to its  original  sum.  Failure by Tenant to so remit  funds  shall be a
Default by Tenant.  Should  Tenant  comply with all of the terms,  covenants and
conditions  of this Lease  applicable  to Tenant,  the  balance of the  Security
Deposit  shall be  returned  to Tenant  within  fourteen  (14) days after  Lease
Termination and surrender of the Premises by Tenant;  provided,  however, if any
portion  of the  Security  Deposit  is to be  applied  to repair  damages to the
Premises  caused by Tenant or  Tenant's  agents,  to clean the  Premises,  or to
remove  alterations  and restore the Premises  pursuant to Paragraph 13.2 below,
then the balance of the  Security  Deposit  shall be returned to Tenant no later
than  thirty  (30)  days  after the date  Landlord  receives  possession  of the
Premises.

         6. Use of Premises.

              6..1 Permitted Uses.  Tenant shall use the Premises and the Common
Area only in  conformance  with  applicable  Laws for the  purposes set forth in
Paragraph 1.9 above,  and for no other purpose without the prior written consent
of  Landlord,  which  consent  shall not be  unreasonably  withheld  or delayed,
provided that such other use is in conformance  with applicable Laws. Any change
in use of the Premises or the Common Area without the prior  written  consent of
Landlord shall be a Default by Tenant.  Tenant and Tenant's  agents shall comply
with  the  provisions  of  any   Declaration  of  Covenants,   Conditions,   and
Restrictions affecting the Premises and the Common Area.

              6..2 Tenant to Comply with Legal  Requirements.  Tenant shall,  at
its sole cost,  promptly comply with all Laws relating to or affecting  Tenant's
particular use or occupancy of the Premises or the Common Area, now in force, or
which may hereafter be in force,  including without limitation those relating to
utility  usage  and load or  number  of  permissible  occupants  or users of the
Premises,  whether or not the same are now contemplated by the parties; with the
provisions of all recorded  documents  affecting the Premises or the Common Area
insofar as the same relate to or affect Tenant's  particular use or occupancy of
the Premises or use of the Common Area; and with the  requirements  of any board
of fire underwriters (or similar body now or hereafter  constituted) relating to
or affecting Tenant's  particular use or occupancy of the Premises or use of the
Common Area. Tenant's  obligations pursuant to this Paragraph 6.2 shall include,
without  limitation,  maintaining  or restoring the Premises and the Common Area
and making structural and non-structural alterations and additions in compliance
and  conformity  with  all  Laws  and  recorded  documents  (including,  without
limitation, alterations or additions to the Premises and/or Common Area that are
required  pursuant to the ADA),  each  relating to  Tenant's  particular  use or
occupancy  of the  Premises  during  the Lease Term or  alterations  made to the
Premises by Tenant.  Any alterations or additions  undertaken by Tenant pursuant
to this  Paragraph 6.2 shall be subject to the  requirements  of Paragraph  13.1
below. At Landlord's option, Landlord may make the required alteration, addition
or  change,  and  Tenant  shall pay the cost  thereof as  Additional  Rent.  The
foregoing  notwithstanding,  Landlord  shall  make any  alteration  or  addition
required to bring the  Premises or the Common  Area into  compliance  with legal
requirements  in effect at the time the  Premises,  any  improvements  installed
therein  by  Landlord,  or  the  Common  Area,  respectively,   were  originally
constructed. The cost of any structural alterations as may be hereafter required
due to a change in laws and  unrelated to Tenant's  specific use of the Premises
shall be the  responsibility  of  Landlord.  

              Tenant shall obtain prior to taking possession of the Premises any
permits,  licenses or other authorizations  required for the lawful operation of
its  business  at  the  Premises.   The  judgment  of  any  court  of  competent
jurisdiction  or the  admission  of Tenant in any action or  proceeding  against
Tenant.  regardless  of whether  Landlord is a party thereto or not, that Tenant
has violated such Law or recorded document  relating to Tenant's  particular use
or occupancy of the  Premises or use of the Common Area shall be  conclusive  of
the fact of such violation by Tenant. 

              6..3 Prohibited Uses.  Tenant and Tenant's agents shall not commit
or suffer to be  committed  any waste upon the  Premises.  Tenant  and  Tenant's
agents  shall not do or permit  anything to be done in or about the  Premises or
Common Area which will in any way obstruct or  interfere  with the rights of any
authorized  users of the Common Area or occupants of  neighboring  property,  or
injure or annoy  them.  Tenant  shall not  conduct or permit any auction or sale
open to the public to be held or  conducted  on or about the  Premises or Common
Area.  Tenant and Tenant's agents shall not use or allow the Premises to be used
for any unlawful,  immoral or hazardous  purpose or any purpose not permitted by
this Lease, nor shall Tenant or Tenant's agents cause,  maintain,  or permit any
nuisance in, on or about the Premises.  Tenant and Tenant's  agents shall not do
or permit  anything to be done in or about the Premises or Common Area nor bring
or keep  anything in the  Premises or Common Area which will in any way increase
the rate of any  insurance  upon the Premises or Common Area or any part thereof
or any of its contents, or cause a cancellation of any insurance policy covering
the  Premises or Common  Area or any part  thereof or any of its  contents,  nor
shall Tenant or Tenant's  agents keep, use or sell or permit to be kept, used or
sold in or about the Premises any articles which may be prohibited by a standard
form policy of fire  insurance.  In the event the rate of any insurance upon the
Premises or Common Area or any part  thereof or any of its contents is increased
because of Tenant's  particular use of the Premises or that of Tenant's  agents,
Tenant shall pay, as Additional  Rent, the full cost of such increase;  provided
however  this  provision  shall in no event be deemed to  constitute a waiver of
Landlord's right to declare a default  hereunder by reason of the act or conduct
of Tenant or Tenant's  agents  causing  such  increase or of any other rights or
remedies of Landlord in connection  therewith.  Tenant and Tenant's agents shall
not place any loads upon the floor. walls or ceiling of the Premises which would
endanger the Premises or the structural elements thereof,  nor place any harmful
liquids in the drainage  system of the  Premises.  No waste  materials or refuse
shall be dumped upon or  permitted  to remain  upon any part of the  Premises or
Common Area except in enclosed trash  containers  designated for that purpose by
Landlord. No materials,  supplies, equipment, finished products (or semifinished
products),  raw materials, or other articles of any nature shall be stored upon,
or be permitted to remain on, any portion of the Common Area.

              6..4 Hazardous Materials. Neither Tenant nor Tenant's agents shall
permit the introduction,  placement, use, storage, manufacture,  transportation,
release or  disposition  (collectively  "Release") of any Hazardous  Material(s)
(defined  below) on or about any portion of the  Premises or Common Area without
the prior written consent of Landlord, which consent may be withheld in the sole
and absolute discretion of Landlord without any requirement of reasonableness in
the  exercise of that  discretion.  Notwithstanding  the  immediately  preceding
sentence to the contrary,  Tenant may use de minimis  quantities of the types of
materials which are technically  classified as Hazardous  Materials but commonly
used in  domestic  or office use to the extent not in an amount,  which,  either
individually  or  cumulatively,  would  be a  "reportable  quantity"  under  any
applicable Law. Tenant covenants that, at its sole cost and expense, Tenant will
comply  with all  applicable  Laws with  respect to the  Release by Tenant,  its
agents,   employees,   contractors  or  invitees  of  such  permitted  Hazardous
Materials.  Any  Release  beyond the scope  allowed in this  paragraph  shall be
subject to Landlord's  prior consent,  which may be withheld in Landlord's  sole
and  absolute  discretion,  and shall  require an  amendment to the Lease in the
event Landlord does consent which shall set forth the  materials,  scope of use,
indemnification and any other matter required by Landlord in Landlord's sole and

at least  thirty  (30) days prior to any  cancellation  or  modification  of any
policy.  Tenant's policies shall provide coverage on an occurrence basis and not

expenses  or  liabilities  for injury or death to any person or for damage to or
loss of use of any property  arising out of any  occurrence  in, on or about the
Premises  or Common  Area,  if caused or  contributed  to by Tenant or  Tenant's

of this  Lease.  The  provisions  of this  Paragraph  8.4  shall  survive  Lease

occurring prior to such termination.  Except as set forth in this Paragraph 8.4,
this Lease is made on the express  condition  that Landlord  shall not be liable

causes, including without limitation,  any defect in the Premises or Common Area
and/or any damage or injury resulting from fire, steam, electricity,  gas, water
or rain,  which may leak or flow from or into any part of the Premises,  or from
breakage,  leakage,  obstruction or other defects of pipes,  sprinklers,  wires,
appliances,  plumbing, air conditioning or lighting fixtures, whether the damage
or injury  results from  conditions  arising upon the Premises or Common Area or
from other sources.  Neither Landlord nor Tenant shall be liable for any damages
arising from any act or negligence of any other user of the Common Area.  Tenant
or Tenant's  agents shall  immediately  notify  Landlord in writing of any known
defect in the Premises or Common Area.  The  provisions  of this  Paragraph  8.5

or negligence, or that of its agents, employees, contractors or invitees.

              8..6  Mutual  Waiver  of  Subrogation.  Landlord  hereby  releases
Tenant,  and Tenant hereby releases  Landlord,  and their  respective  officers,
agents,  employees and servants,  from any and all claims or demands of damages,
loss,  expense  or  injury  to  the  Premises  or  the  Common  Area,  or to the
furnishings, fixtures, equipment, inventory or other property of either Landlord
or Tenant in, about or upon the Premises or the Common Area,  which is caused by
or results from perils,  events or happenings which are the subject of insurance
carried by the respective  parties  pursuant to this Paragraph 8 and in force at
the time of any such loss,  whether due to the  negligence of the other party or
its  agents and  regardless  of cause or origin;  provided,  however,  that such
waiver shall be effective only to the extent permitted by the insurance covering
such loss, to the extent such  insurance is not prejudiced  thereby,  and to the
extent insured against.

         9.  Utilities.  Tenant  shall pay  during  the Lease  Term and prior to
delinquency  all  charges  for water,  gas,  light,  heat,  power,  electricity,

therefor.  Tenant shall  arrange for Services to be supplied to the Premises and
shall  contract  for  all  of  the  Services  in  Tenant's  name  prior  to  the

failure  by Tenant to so  contract  for  Services.  In the event that any of the
Services  cannot be separately  billed or metered to the Premises,  or if any of
the Services are not separately metered as of the Commencement Date, the cost of
such  Services  shall be an Operating  Expense and Tenant shall pay such cost to
Landlord,  as Additional  Rent,  as provided in Paragraph 12 below,  except that
Tenant's  proportionate  share of such Services shall be the percentage obtained

Services.  The lack or  shortage  of any  Services  due to any cause  whatsoever
(except  for a lack or  shortage  proximately  caused by the  negligent  acts or
willful  misconduct  Landlord or that of its agents,  employees,  contractors or
invitees) shall not affect any obligation of Tenant hereunder,  and Tenant shall
faithfully  keep and observe all the terms,  conditions  and  covenants  of this
Lease and pay all  Rentals due  hereunder,  all  without  diminution,  credit or
deduction.

the expense of Tenant and as Additional Rent.

              10..2 Tenant's  Responsibilities.  Except as expressly provided in

maintenance  (except for the negligent  acts or willful  misconduct  Landlord or
that of its agents, employees,  contractors or invitees). Tenant shall reimburse
Landlord,  on  demand  and as  Additional  Rent,  for the cost of  damage to the
Premises  and/or  Common  Area  caused  by  Tenant or  Tenant's  agents.  Tenant
expressly  waives  the  benefits  of any  statute  now or  hereafter  in  effect
(including  without  limitation  the provisions of subsection 1 of Section 1932,
Section 1941 and Section 1942 of the California  Civil Code and any similar law,
statute or ordinance  now or hereafter in effect) which would  otherwise  afford
Tenant the right to make repairs at Landlord's expense (or to deduct the cost of
such repairs from Rentals due  hereunder) or to terminate  this Lease because of
Landlord's  failure to keep the Premises in good and sanitary order.  

         11.  Common Area.

              11..1 In  General.  Subject  to the terms and  conditions  of this
Lease  and  such  rules  and  regulations  as  Landlord  may  from  time to time
prescribe,  Tenant and Tenant's agents shall have the nonexclusive  right to use
during the Lease Term the access roads,  sidewalks,  landscaped  areas and other
facilities on the Common Area. This right to use the Common Area shall terminate
upon Lease  Termination.  Neither  Tenant nor Tenant's  agents shall at any time
park or permit the  parking of their  vehicles in any portion of the Common Area
not  designated  by Landlord as a parking area.  

              Landlord  reserves the right to promulgate such  reasonable  rules
and regulations relating to the use of all or any portion of the Common Area and
to amend such rules and  regulations  from time to time, with or without advance
notice,  as  Landlord  may deem  appropriate.  Any  amendments  to the rules and
regulations  shall be  effective  as to Tenant,  and  binding  on  Tenant,  upon
delivery of a copy of such rules and regulations to Tenant.  Tenant and Tenant's
agents  shall  observe such rules and  regulations  and any failure by Tenant or
Tenant's agents to observe and comply with the rules and regulations  shall be a
Default by Tenant.  Landlord shall not be responsible for the  nonperformance of
the rules and  regulations  by any  tenants or  occupants  of the  buildings  or
improvements  which now exist or may  hereafter be  constructed  upon the Common
Area or upon the real property owned by Landlord  adjacent to the Common Area or
by any other user authorized by Landlord.  

              Provided  that  Tenant's  use,  occupancy  and  enjoyment  of  the
Premises or access to the Premises is not unreasonably interfered with, Landlord
shall have the right to close,  at reasonable  times,  all or any portion of the
Common  Area for any  reasonable  purpose,  including  without  limitation,  the
prevention  of a dedication  thereof,  or the accrual of rights of any person or
public therein.

              11..2 Maintenance by Landlord.  Landlord shall maintain the Common
Area in good repair and condition and shall manage the Common Area to reasonable
and customary  standards.  The expenditures for such maintenance shall be at the
reasonable  discretion  of Landlord.  The cost of such  maintenance  shall be an
"Operating Expense",  and Tenant shall pay such costs to Landlord, as Additional
Rent,  as provided in Paragraph 12 below.  Alternatively,  Landlord may elect at
any time, at its option,  to require Tenant to operate,  manage and maintain all
or any portion of the Common Area. If Landlord so elects,  Tenant shall operate,
manage and maintain  that portion of the Common Area  designated  by Landlord at
Tenant's sole cost and expense.

         12.  Operating Expenses.

              12..1 Definition.  "Operating Expense" or "Operating  Expenses" as
used in this  Lease  shall  mean  and  include  all  items  identified  in other
paragraphs  of this  Lease as an  Operating  Expense  and the total cost paid or
incurred by Landlord for the operation,  maintenance,  repair, and management of
the Premises and Common Area, which costs shall include, without limitation: the
cost of Services and utilities  supplied to the Premises and Common Area (to the
extent the same are not separately charged or metered to Tenant); water; sewage;
trash removal;  fuel;  electricity;  heat;  lighting  systems;  fire  protection
systems;  storm  drainage and sanitary sewer  systems;  periodic  inspection and
regular  servicing of the heating and air conditioning  systems of the Premises;
maintaining,  repairing and replacing the roof membrane;  property and liability
insurance  covering  the Premises  and any other  insurance  carried by Landlord
pursuant to Paragraph 8 above; window cleaning;  cleaning,  sweeping,  striping,
resurfacing  of parking and driveway  areas;  cleaning the Common Area following
storms or other severe  weather;  cleaning and  repairing of  sidewalks,  curbs,
stairways; costs related to irrigation systems; the cost of complying with Laws,
including, without limitation, maintenance,  alterations and repairs required in
connection therewith (subject to the provisions of Paragraph 12.3 hereof); costs
related to landscape  maintenance;  and the cost of  contesting  the validity or
applicability  of  any  governmental   enactments  which  may  affect  Operating
Expenses.  If the Common Area is used by more than one (1)  building at any time
during the Lease Term, then the term "Operating Expenses" shall mean and include
all of the  Operating  Expenses  allocable to the  Premises and a  proportionate
share (based on the square  footage of gross  leasable area in the Premises as a
percentage  of the  total  of  square  footage  of  gross  leasable  area of the
buildings  utilizing  the Common Area at the time in question) of all  Operating
Expenses which are related to such buildings in general and are not allocated to
any one  building  utilizing  the Common  Area.  Operating  Expenses  shall also
include a management  fee to Landlord in an amount equal to ten percent (10%) of
the total Operating Expenses.  The cost of (i) capital repair items (i.e., items
which Landlord is required to capitalize and not expense in the current year for
federal income tax  purposes),  (ii)  replacement  of the roof  membrane,  (iii)
resurfacing  the parking lot, and (iv)  repainting the exterior of the Premises,
shall be  amortized  at ten percent  (10%) over the useful life of the repair or
item,  and be paid  monthly by Tenant  from the date of  installation  or repair
through Lease Termination.

              The  specific  examples  of  Operating  Expenses  stated  in  this
Paragraph  12.1  are in no way  intended  to  and  shall  not  limit  the  costs
comprising  Operating  Expenses,  nor shall such  examples be deemed to obligate
Landlord to incur such costs or to provide such services or to take such actions
except as Landlord may be expressly required in other portions of this Lease, or
except as Landlord,  in its  reasonable  discretion,  may elect.  All reasonable
costs incurred by Landlord in good faith for the operation,  maintenance, repair
and  management  of the  Premises  and Common Area shall be deemed  conclusively
binding on Tenant.

              Notwithstanding  anything to the contrary contained in this Lease,
within  thirty  (30) days after  receipt by Tenant of  Landlord's  statement  of
Operating  Expenses  prepared  pursuant to  Paragraph  12.2 hereof for any prior
annual period  during the Lease Term,  Tenant or its  authorized  representative
shall have the right to inspect the books of Landlord  during the business hours
of Landlord at Landlord's office or, at Landlord's  option,  such other location
as Landlord reasonably may specify, for the purpose of verifying the information
contained in the statement.  Unless Tenant asserts specific errors within thirty
(30) days after receipt of the statement,  the statement shall be deemed correct
as between Landlord and Tenant, except as to individual components  subsequently
determined to be in error by future audit. 

              12..2  Payment  of  Operation  Expenses  by  Tenant.  Prior to the
Commencement Date, and annually thereafter,  Landlord shall deliver to Tenant an
estimate of Operating  Expenses for the  succeeding  year.  Tenant's  payment of
Operating Expenses shall be based upon Landlord's estimate of Operating Expenses
and shall be payable in equal monthly  installments  in advance on the first day
of each calendar  month  commencing  on  the date specified in Paragraph 1.6 and
continuing throughout the Lease Term. Tenant shall pay the Operating Expenses to
Landlord as  Additional  Rent and without  deduction or offset.  

              Landlord  shall revise its  estimate of  Operating  Expenses on an
annual basis, and Landlord may adjust the amount of Tenant's monthly installment
in the  event of a  material  change  in  Operating  Expenses  during  any year.
Landlord  shall furnish Tenant an annual  statement (and a statement  within one
hundred eighty (180) days after Lease Termination)  showing the actual Operating
Expenses  for the  period  to  which  Landlord's  estimate  pertains  and  shall
concurrently  either bill Tenant for the  balance  due  (payable  upon demand by
Landlord) or credit Tenant's account for the excess previously paid.

              Alternatively,  Operating  Expenses  actually  incurred or paid by
Landlord but not theretofore billed to Tenant, as invoiced by Landlord, shall be
payable by Tenant within ten (10) days after receipt of Landlord's invoice,  but
not more often than once each calendar month.

              12..3   Exclusions  From  Common  Area  Charges.   Notwithstanding
anything to the contrary  contained in this Lease, in no event shall Tenant have
any obligation to perform, to pay directly, or to reimburse Landlord for, all or
any portion of the following repairs, maintenance,  improvements,  replacements,
premiums, claims, losses, fees, commissions,  charges, disbursements, attorneys'
fees, experts' fees, costs and expenses (collectively, "Costs").

occasioned by the act,  omission or violation of Law by Landlord,  or Landlord's
agents, employees or contractors, or Costs to correct any construction defect in
the Premises (other than  alterations  constructed by Tenant),  or costs arising
out of the failure to construct the Premises,  tenant improvements  installed by
Landlord  pursuant to Paragraph 2.2, or Common Areas in accordance with Laws and
private restrictions applicable at the time of construction thereof.

                     (b) Condemnation Costs. Costs occasioned by the exercise of
the power of eminent domain.

                     (c) Reimbursable  Expenses.  Costs for which Landlord has a
right of  reimbursement  from others,  or Costs which Tenant pays  directly to a
third person.

                     (d) Reserves.  Depreciation,  amortization or other expense
reserves.

                     (e) Mortgages. Interest, charges and fees incurred on debt,
payments or mortgages and rent under ground leases.

                     (f) Hazardous Materials.  Costs incurred to investigate the

Material  contamination or damage,  Costs to remove any Hazardous  Material from
the  Premises  or  Common  Area  or  to   remediate   any   Hazardous   Material
contamination,  and any judgments or other Costs incurred in connection with any
Hazardous  Material  exposure  or  release,  except to the extent such Costs are
incurred by Landlord in accordance with Paragraph 6.4 or incurred by Landlord or
caused by reason of the storage,  use  or  disposal of the Hazardous Material in
question  by  Tenant,  its  agents,  employees,  contractors  or  invitees.  

                     (g) Management. Any fee, profit or compensation retained by

structural  alterations  required  by Law that do not relate  solely to Tenant's
particular use or occupancy of the Premises,  and Costs of retrofitting any part
of the  Common  Area in order to  comply  with  the ADA  (other  than as they be
required in connection with the improvements  installed by Landlord  pursuant to
Paragraph 2.2.).

         13.  Alterations and Improvements.

              13..1 In General. Tenant shall not make, or permit to be made, any
alterations,   removals,  changes,   enlargements,   improvements  or  additions
(collectively  "Alterations")  in,  on,  about or to the  Premises,  or any part
thereof,  including  Alterations required pursuant to Paragraph 6.2, without the
prior  written  consent of Landlord  (which  consent  shall not be  unreasonably
withheld or delayed) and without  acquiring and complying with the conditions of
all permits required for such  Alterations by any governmental  authority having
jurisdiction  thereof. The term "Alterations" as used in this Paragraph 13 shall
also include all heating,  lighting,  electrical (including all wiring, conduit,
outlets,  drops,  buss  ducts,  main  and  subpanels),  air  conditioning,   and
partitioning  in the Premises  made by Tenant,  regardless of how affixed to the
Premises. As a condition to the giving of its consent,  Landlord may impose such
reasonable  requirements as Landlord  reasonably may deem  necessary,  including
without limitation, the manner in which the work is done; a right of approval of
the contractor by whom the work is to be performed;  the requirement that Tenant
post a  completion  bond  in an  amount  and  form  reasonably  satisfactory  to
Landlord;  and the requirement  that Tenant  reimburse  Landlord,  as Additional
Rent, for Landlord's actual costs for outside consultants  incurred in reviewing
any proposed  Alteration,  whether or not Landlord's consent is granted.  In the
event Landlord  consents to the making of any  Alterations  by Tenant,  the same
shall be made by Tenant at Tenant's sole cost and expense,  in  accordance  with
the plans and  specifications  approved by  Landlord.  Tenant shall give written
notice to Landlord five (5) days prior to employing any laborer or contractor to
perform services  related to, or receiving  materials for use upon the Premises,
and prior to the  commencement  of any work of improvement on the Premises.  Any
Alterations  to the  Premises  made by Tenant shall be made in  accordance  with
applicable  Laws and in a  first-class  workmanlike  manner.  In making any such
Alterations,  Tenant  shall,  at Tenant's  sole cost and  expense,  file for and
secure  and  comply  with  any and all  permits  or  approvals  required  by any
governmental  departments or  authorities  having  jurisdiction  thereof and any
utility company having an interest  therein.  In no event shall Tenant  make any
structural  changes to the  Premises or make any changes to the  Premises  which
would weaken or impair the structural integrity of the Premises.

              13..2 Removal Upon Lease Termination.  At the time Tenant requests
Landlord's consent,  Tenant shall request a decision from Landlord in writing as
to whether Landlord will require Tenant, at Tenant's expense, to remove any such
Alterations  and  restore  the  Premises  to  their  prior  condition  at  Lease
Termination.  In the event Tenant  fails to earlier  obtain  Landlord's  written
decision as to whether Tenant will be required to remove any Alteration, then no
less than ninety (90) nor more than one hundred  twenty  (120) days prior to the
expiration of the Lease Term, Tenant by written notice to Landlord shall request
Landlord to inform  Tenant  whether or not Landlord  desires to have any of such
Alterations by Tenant removed at Lease  Termination.  Following  receipt of such
notice,  Landlord may elect to have all or a portion of such Alterations removed
from the Premises at Lease  Termination,  and Tenant shall, at its sole cost and
expense, remove at Lease Termination such Alterations designated by Landlord for
removal and repair all damage to the  Premises and Common Area arising from such
removal. In the event Tenant fails to so request Landlord's decision or fails to
remove any such  Alterations  designated  by Landlord for removal,  Landlord may
remove any  Alterations made to the Premises by  Tenant and repair all damage to
the Premises and Common Area  arising  from such  removal,  and may recover from
Tenant all reasonable costs and expenses incurred thereby.  Tenant's  obligation
to pay such costs and  expenses to Landlord  shall  survive  Lease  Termination.
Unless  Landlord  elects to have Tenant  remove (or,  upon  Tenant's  failure to
obtain Landlord's  decision,  Landlord  removes) any such Alterations,  all such
Alterations, except for moveable furniture, personal property and equipment, and
trade fixtures of Tenant not affixed to the Premises,  shall become the property
of Landlord  upon Lease  Termination  (without any payment  therefor) and remain
upon  and be  surrendered  with  the  Premises  at  Lease  Termination.  

              13..3  Landlord's  Improvements.  All  fixtures,  improvements  or
equipment  which are  installed,  constructed  on or attached to the Premises or
Common Area by Landlord shall be a part of the realty and belong to Landlord.

         14.  Default and Remedies.

              14..1 Events of Default.  The term  "Default by Tenant" as used in
this Lease shall mean the occurrence of any of the following events:

                     (a)  Tenant's  failure  to pay  when  due any  Rentals;  

                     (b)  Commencement  and continuation for at least sixty (60)

Code  concerning  Tenant,  whether  under  Chapter 7, 11, or 13 of such Title or

financial reorganization or an arrangement with any of Tenant's creditors;

                     (c)  Voluntary or  involuntary  appointment  of a receiver,
trustee,  keeper,  or other person who takes possession for more than sixty (60)
days of  substantially  all of Tenant's  assets or of any asset used in Tenant's
business on the Premises,  regardless of whether such appointment is as a result
of insolvency or any other cause

                     (d) Execution of an assignment for the benefit of creditors
of  substantially  all assets of Tenant available by law for the satisfaction of
judgment creditors;

                     (e)   Commencement   of  proceedings   for  winding  up  or
dissolving (whether voluntary or involuntary) the entity of Tenant, if Tenant is
a corporation or a partnership

                     (f) Levy of a writ of  attachment  or execution on Tenant's
interest  under this Lease,  if such writ  continues for a period of thirty (30)
days;

                     (g)  Transfer  or  attempted  Transfer of this Lease or the
Premises by Tenant contrary to the provisions of Paragraph 24 below; or

warranty,  or other provision contained in this Lease or of any other obligation
owing or due to Landlord.

              14..2  Remedies.  Upon any Default by Tenant,  Landlord shall have
the following remedies, in addition to all other rights and remedies provided by
law, to which Landlord may resort cumulatively, or in the alternative:

                     14..2.1  Termination.  Upon any Default by Tenant, Landlord
shall have die right (but not the  obligation)  to give written notice to Tenant
of such default and terminate this Lease and Tenant's right to possession of the
Premises  if (i) such  default is in the  payment  of  Rentals  and is not cured
within  seven (7) days  after any such  notice,  or,  (ii) with  respect  to the
defaults referred to in subparagraphs 14.1(d), (e), (g) and (h), such default is
not cured within  thirty (30) days after any such notice (or if a default  under
subparagraph  14.1(h)  cannot be reasonably  cured within thirty (30) clays,  if
Tenant does not  commence to cure the default  within the thirty (30) day period
or does not diligently and in good faith prosecute the cure to completion),  or,
(iii) with respect to the defaults specified in subparagraphs  14.1(b),  (c) and
(f), such default is not cured within the respective  time periods  specified in
those  subparagraphs.  The parties  agree that any  notice  given by Landlord to
Tenant pursuant to this Paragraph 14.2.1 shall be sufficient notice for purposes
of California  Code of Civil  Procedure  Section 1161 and Landlord  shall not be
required  to give any  additional  notice in order to be entitled to commence an
unlawful detainer proceeding.  Upon termination of this Lease and Tenant's right
to  possession of the  Premises,  Landlord  shall have the right to recover from
Tenant:

                         (a) The  worth  at the  time  of  award  of the  unpaid
Rentals which had been earned at the time of termination;

                         (b) The  worth at the time of  award of the  amount  by
which the Rentals which would have been earned after  termination until the time
of award  exceeds the amount of such rental loss that Tenant  proves  could have
been reasonably avoided;

                         (c) The  worth  at  the  time  of  award  (computed  by
discounting at the discount rate of the Federal Reserve Bank of San Francisco at
the time of award plus one  percent)  of the amount by which the Rentals for the
balance  of the Lease  Term  after the time of award  exceed  the amount of such
rental loss that Tenant proves could be reasonably avoided;

                         (d) Any other amounts necessary to compensate  Landlord
for all  detriment  proximately  caused by the Default by Tenant or which in the
ordinary course of events would likely result,  including without limitation the
following:

                            (i) Expenses in retaking possession of the Premises;

                            (ii) Expenses for  cleaning,  repairing or restoring
the Premises;

                            (iii)  Any   unamortized   real   estate   brokerage
commission paid in connection with this Lease;

                            (iv)  Expenses  for  removing,   transporting,   and
storing any of Tenant's property left at the Premises  (although  Landlord shall
have no  obligation  to  remove,  transport,  or store any such  property);  

                            (v) Expenses of reletting  the  Premises,  including
without limitation,  brokerage  commissions and reasonable attorneys' fees; 

                            (vi) Reasonable attorneys' fees and court costs; and

                            (vii)  Costs  of  carrying  the  Premises   such  as
repairs,  maintenance,  taxes and  insurance  premiums,  utilities  and security
precautions (if any).

                         (e) The  "worth at the time of  award"  of the  amounts
referred to in subparagraphs (a) and (b) of this Paragraph 14.2.1 is computed by
allowing  interest at an annual rate equal to the greater of: ten percent (10%);
or five percent (5%) plus the rate  established  by the Federal  Reserve Bank of
San  Francisco,  as of the  twenty-fifth  (25th)  day of the  month  immediately
preceding the Default by Tenant,  on advances to member banks under  Sections 13
and 13(a) of the Federal  Reserve Act, as now in  effect or hereafter  from time
to time amended, not to exceed the maximum rate allowable by law.

                     l4..2.2  Continuance  of Lease.  Upon any Default by Tenant
and  unless and until  Landlord  elects to  terminate  this  Lease  pursuant  to
Paragraph  14.2.l  above,  this Lease shall continue in effect after the Default
by Tenant and Landlord may enforce all its rights and remedies under this Lease,
including  without  limitation,  the right to recover payment of Rentals as they
become due.  Neither efforts by Landlord to mitigate damages caused by a Default
by  Tenant  nor the  acceptance  of any  Rentals  shall  constitute  a waiver by
Landlord  of any of  Landlord's  rights or  remedies,  including  the rights and
remedies specified in Paragraph 14.2.1 above.

         15.  Damage or Destruction.

              15..1  Definition  of Terms.  For the purposes of this Lease,  the
term: (a) "Insured Casualty" means damage to or destruction of the Premises from
a cause  actually  insured  against,  or  required  by this  Lease to be insured
against, for which the insurance proceeds paid or made available to Landlord are
sufficient to rebuild or restore the Premises under then-existing building codes
to the condition  existing  immediately prior to the damage or destruction;  and
(b) "Uninsured  Casualty"  means damage to or destruction of the Premises from a
cause not actually  insured against,  or not required to be insured against,  or
from a cause actually insured against but for which the insurance  proceeds paid
or made  available  to Landlord  are for any reason  insufficient  to rebuild or
restore  the  Premises  under  then-existing  building  codes  to the  condition
existing  immediately  prior  to the  damage  or  destruction,  or  from a cause
actually  insured  against but for which the insurance  proceeds are not paid or
made  available  to Landlord  within  ninety (90) days of the event of damage or
destruction.

              15..2 Insured Casualty.

                     15..2.1  Rebuilding  Required.  In  the event of an Insured
Casualty  where the  extent of damage or  destruction  is less than  twenty-five
percent (25%) of the then full replacement cost of the Premises,  Landlord shall
rebuild or restore the Premises to the condition  existing  immediately prior to
the damage or  destruction,  provided the damage or destruction was not a result
of a negligent  or willful act of Tenant,  and that there exist no  governmental
codes or regulations that would interfere with Landlord's  ability to so rebuild
or restore.  

                     15..2.2  Landlord's  Election.  In the event of an  Insured
Casualty  where the extent of damage or  destruction is equal to or greater than
twenty-five  percent  (25%) of the then full  replacement  cost of the Premises,
Landlord may, at its option and at its sole  discretion,  rebuild or restore the
Premises  to  the  condition  existing   immediately  prior  to  the  damage  or
destruction,  or terminate  this Lease.  Landlord shall notify Tenant in writing
within sixty (60) days after the event of damage or  destruction  of  Landlord's
election to either rebuild or restore the Premises or terminate this Lease.

                     15.2.3  Continuance  of Lease.  If  Landlord is required to
rebuild or restore  the  Premises  pursuant to  Paragraph  15.2.1 or if Landlord
elects to rebuild or restore the  Premises  pursuant to Paragraph  15.2.2,  this
Lease shall remain in effect and Tenant shall have no claim against Landlord for
compensation  for  inconvenience or loss of business during any period of repair
or restoration.

         15..3 Uninsured Casualty.

                     15..3.1 Landlord's Election.  In the event of an Uninsured
Casualty,  Landlord may, at its option and at its sole discretion (i) rebuild or
restore  the  Premises as soon as  reasonably  possible  at  Landlord's  expense
(unless the damage or  destruction  was caused by a negligent  or willful act of
Tenant,  in which event Tenant shall pay all costs of rebuilding or  restoring),
in which  event  this  Lease  shall  continue  in full  force and effect or (ii)
terminate  this Lease,  in which event  Landlord  shall give  written  notice to
Tenant  within  sixty  (60) days  after the  event of damage or  destruction  of
Landlord's  election  to  terminate  this  Lease as of the date of the  event of
damage  or  destruction,  and if the  damage  or  destruction  was  caused  by a
negligent or willful act of Tenant, Tenant shall be liable therefor to Landlord.

                     15..3.2  Tenant's  Ability to Continue  Lease.  If Landlord
elects to terminate  this Lease and the extent of damage or  destruction is less
than twenty-five percent (25%) of the then full replacement cost of the Premises
or the  proceeds  paid  or  made  available  to  Landlord  are  for  any  reason
insufficient  to rebuild or restore the Premises  under  then-existing  building
codes to the condition existing  immediately prior to the damage or destruction,
and if there exist no  governmental  codes or regulations  that would  interfere
with Landlord's  ability to so repair or restore,  then Tenant may  nevertheless
cause the Lease to  continue  in effect by (i)  notifying  Landlord  in  writing
within  ten (10)  days  after  Landlord's  notice  of  termination  of  Tenant's
agreement to pay all costs of  rebuilding or restoring not covered by insurance,
and (ii) providing  Landlord with  reasonable  security for or assurance of such
payment.  Tenant  shall pay to  Landlord  in cash no later than thirty (30) days
prior to the date of commencement of construction the reasonable  estimated cost
of  rebuilding  or  restoring.  In  the event  Tenant  fails to pay such cost to
Landlord by the date specified, Landlord may immediately terminate the Lease and
recover from Tenant all reasonable costs incurred by Landlord in preparation for
construction.  If the  actual  cost  of  rebuilding  or  restoring  exceeds  the
estimated cost of such work, Tenant shall pay the difference to Landlord in cash
upon  notification  by Landlord of the final cost.  If the cost of rebuilding or
restoring is less than the estimated cost of such work, Tenant shall be entitled
to a refund of the difference upon completion of the rebuilding or restoring and
determination of final cost.

              15..4 Tenant's Election.  Notwithstanding anything to the contrary
contained in this  Paragraph 15, Tenant may elect to terminate this Lease in the
event the Premises are damaged or destroyed  and, in the  reasonable  opinion of
Land1ord's  architect  or  construction  consultants,  the  restoration  of  the
Premises cannot be substantially  completed within one hundred eighty (180) days
after the event of damage or  destruction.  Tenant's  election  shall be made by
written  notice to  Landlord  within ten (10) days after  Tenant  receives  from
Landlord the estimate of the time needed to complete  repair or  restoration  of
the  Premises.  If Tenant does not deliver said notice  within said ten (10) day
period, Tenant may not later terminate this Lease even if substantial completion
of the  rebuilding or restoration  occurs  subsequent to said one hundred eighty
(180) day period, provided that Landlord is proceeding with diligence to rebuild
or restore the Premises. If Tenant delivers said notice within said ten (10) day
period,  this  Lease  shall  terminate  as of the date of the event of damage or
destruction.

              15..5   Damage   or   Destruction   Near   End  of   Lease   Term.
Notwithstanding  anything to the contrary contained in this Paragraph 15, in the
event the Premises are damaged or destroyed in whole or in part  (regardless  of
the extent of damage)  from any cause  during the last twelve (12) months of the
Lease Term,  Landlord or Tenant may, at its option,  terminate  this Lease as of
the date of the event of damage or  destruction  by giving written notice to the
other of its  election to do so within  thirty (30) days after the event of such
damage or  destruction.  For purposes of this Paragraph 15.5, if Tenant has been
granted  an  option  to extend or renew  the  Lease  Term  pursuant  to  another
provision of this Lease,  then the damage or destruction shall be deemed to have
occurred during the last twelve (12) months of the Lease Term if Tenant fails to
exercise its option to extend or renew  within  twenty (20) days after the event
of  damage  or  destruction.  

              15..6 Termination of Lease. If the Lease is terminated pursuant to
this Paragraph 15, the unused balance of the Security  Deposit shall be refunded
to Tenant. The current Rent shall be  proportionately  reduced during the period
following  the  event of damage or  destruction  until the date on which  Tenant
surrenders  the  Premises,  based  upon  the  extent  to  which  the  damage  or
destruction  interferes  with Tenant's  business  conducted in the Premises,  as
reasonably determined by Landlord and Tenant, to the extent such loss is covered
as an insured peril by the insurance  carried by Landlord  pursuant to Paragraph
8.1. All other  Rentals due  hereunder  shall  continue  unaffected  during such
period.  The proceeds of insurance  carried by Tenant  pursuant to Paragraph 8.2
shall  be paid to  Landlord  and  Tenant,  as their  interests  appear.  

              15..7  Abatement of Rentals.  If the Premises are to be rebuilt or
restored  pursuant  to this  Paragraph  15, the then  current  Rentals  shall be
proportionately  reduced during the period of repair or restoration,  based upon
the extent to which the  making of repairs  interferes  with  Tenant's  business
conducted in the Premises,  as reasonably  determined by Landlord and Tenant, to
the extent such loss is covered as an insured peril by the insurance carried, or
required to be carried,  by Landlord pursuant to Paragraph 8.1. 

              15..8  Liability for Personal  Property.  Except for the negligent
acts  or  willful  misconduct  Landlord  or  that  of  its  agents,   employees,
contractors or invitees,  in no event shall Landlord have any liability for, nor
shall it be  required  to  repair  or  restore,  any  injury  or  damage  to any
Alterations  to  the  Premises  made  by  Tenant,  trade  fixtures,   equipment,
merchandise,  furniture,  or any other  property  installed  by Tenant or at the
expense of Tenant.  If Landlord or Tenant do not elect to  terminate  this Lease
pursuant to this Paragraph 15, Tenant shall be obligated to promptly  rebuild or
restore the same to the condition  existing  immediately  prior to the damage or
destruction in accordance  with the provisions of Paragraph  13.1. 

              15..9  Waiver  of  Civil  Code   Remedies.   Landlord  and  Tenant
acknowledge  that the rights  and  obligations  of the  parties  upon  damage or
destruction  of the Premises are as set forth  herein;  therefore  Tenant hereby
expressly  waives any rights to terminate  this Lease upon damage or destruction
of the  Premises,  except as  specifically  provided  by this  Lease,  including
without  limitation  any rights  pursuant to the  provisions of Subdivision 2 of
Section 1932 and Subdivision 4 of Section 1933 of the California  Civil Code, as
amended from time to time,  and the  provisions  of any similar law  hereinafter
enacted,  which  provisions  relate to the  termination of the hiring of a thing
upon its substantial damage or destruction. 

         16.  Condemnation. 

              16..1  Definition  of Terms.  For the purposes of this Lease,  the
term:  (a)  "Taking"  means a taking of the  Premises  or Common  Area or damage
related to the  exercise of the power of eminent  domain and  includes,  without
limitation, a voluntary conveyance, in lieu of court proceedings, to any agency,
authority,  public  utility,  person or  corporate  entity  empowered to condemn
property; (b) "Total Taking" means the Taking of the entire  Premises or so much
of the  Premises  or Common Area as to prevent or  substantially  impair the use
thereof by Tenant for the uses herein specified  provided,  however,  that in no
event  shall the Taking of less than  twenty  percent  (20%) of the  Premises be
considered  a Total  Taking;  (c)  "Partial  Taking"  means the Taking of only a
portion of the Premises or Common Area which does not constitute a Total Taking;
(d) "Date of  Taking"  means the date upon  which the title to the  Premises  or
Common Area or a portion  thereof,  passes to and vests in the  condemnor or the
effective  date of any order for  possession  if issued  prior to the date title
vests in the  condemnor;  and (e)  "Award"  means the amount of any award  made,
consideration paid, or damages ordered as a result of a Taking.

              16..2 Rights.  The parties agree that in the event of a Taking all
rights between them or in and to an Award shall be as set forth herein.

              16..3  Total  Taking.  In the event of a Total  Taking  during the
Lease Term:  (a) the rights of Tenant under this Lease and the leasehold  estate
of Tenant in and to the  Premises  shall cease and  terminate  as of the Date of
Taking;  (b)  Landlord  shall  refund to Tenant any prepaid  Rent and the unused
balance of the  Security  Deposit (c) Tenant  shall pay Landlord any Rentals due
Landlord under the Lease,  prorated as of the Date of Taking;  (d) to the extent
the Award is not payable to the  beneficiary  or mortgagee of a deed of trust or
mortgage  affecting  the  Premises,  Tenant  shall  receive from the Award those
portions of the Award  attributable  to trade  fixtures  of Tenant;  and (e) the
remainder of the Award shall be paid to and be the property of Landlord. Nothing
contained  in this  Paragraph  16.3 shall be deemed to deny  Tenant its right to
recover  awards made by the  condemning  authority for moving costs,  relocation
costs, and costs attributable to goodwill and leasehold  improvements  installed
by Tenant.

              16..4 Partial Taking.  In the event of a Partial Taking during the
Lease Term: (a) the rights of Tenant under the Lease and the leasehold estate of
Tenant in and to the portion of the Premises  taken shall cease and terminate as
of the Date of  Taking;  (b) from and after the Date of Taking the Rent shall be
an amount equal to the product  obtained by multiplying the then current Rent by
the  quotient  obtained  by  dividing  the fair  market  value  of the  Premises
immediately  after  the  Taking  by  the  fair  market  value  of  the  Premises
immediately  prior to the Taking;  (c) to the extent the Award is not payable to
the  beneficiary  or  mortgagee  of a deed of trust or  mortgage  affecting  the
Premises,  Tenant  shall  receive  from the  Award  the  portions  of the  Award
attributable  to trade  fixtures of Tenant;  and (d) the  remainder of the Award
shall  be paid  to and be the  property  of  Landlord.  Each  party  waives  the
provisions of  California  Code of Civil  Procedure  Section  1265.130  allowing
either party to petition the Superior Court to terminate this Lease in the event
of a Partial Taking. Nothing contained in this Paragraph 16.4 shall be deemed to
deny Tenant its right to recover  awards made by the  condemning  authority  for
moving costs, relocation costs, and costs attributable to goodwill and leasehold
improvements  installed  by Tenant.  

         17.  Liens.  

              17..1  Premises  To  Be  Free of Liens.  Tenant  shall pay for all
labor and  services  performed  for, and all  materials  used by or furnished to
Tenant,  Tenant's agents,  or any contractor  employed by Tenant with respect to
the Premises. Tenant shall indemnify, defend and hold Landlord harmless from and
keep the  Premises  and  Common  Area  free from  any  liens,  claims,  demands,
encumbrances, or judgments, including all costs, liabilities and attorneys' fees
with  respect  thereto,  created or  suffered by reason of any labor or services
performed for, or materials used by or furnished to Tenant or Tenant's agents or
any contractor  employed by Tenant with respect to the Premises.  Landlord shall
have the  right,  at all  times,  to post and keep  posted on the  Premises  any
notices  permitted or required by law, or which Landlord shall deem proper,  for
the protection of Landlord and the Premises and Common Area, and any other party
having an interest therein,  from mechanics' and materialmen's liens,  including
without  limitation  a notice  of  non-responsibility.  In the  event  Tenant is
required to post an  improvement  bond with a public agency in  connection  with
any  work  performed  by  Tenant on or to the  Premises,  Tenant  shall  include
Landlord  as an  additional  obligee.  

              17..2  Notice of Lien;  Bond.  Should  any claims of lien be filed
against, or any action be commenced affecting,  the Premises,  Tenant's interest
in the Premises or the Common Area,  Tenant shall give  Landlord  notice of such
lien or action within five (5) business days after Tenant receives notice of the
filing of the lien or the  commencement of the action.  In the event that Tenant
shall not,  within twenty (20) days  following the  imposition of any such lien,
cause such lien to be released of record by payment or posting of a proper bond,
Landlord  shall have, in addition to all other remedies  provided  herein and by
law, the right, but not the obligation, to cause the same to be released by such
means as Landlord shall deem proper,  including payment of the claim giving rise
to such lien or posting of a Proper bond. All such sums paid by Landlord and all
expenses incurred by Landlord in connection therewith, including attorneys' fees
and costs, shall be payable to Landlord by Tenant as Additional Rent on demand.

         18. Landlord's Right of Access to Premises. Landlord reserves and shall
have the  right and  Tenant  and  Tenant's  agents  shall  Permit  Landlord  and
Landlord's  agents to enter the Premises at any  reasonable  time during  normal
business hours (except in the event of an emergency) and subject to any security
measures  of  Tenant  that  are  applied  to  visitors  to  the  Premises  on  a
non-discriminatory  basis for the purpose of (i) inspecting  the Premises,  (ii)
performing Landlord's maintenance and repair  responsibilities set forth herein,
(iii) posting  notices of  nonresponsibility,  (iv) placing upon the Premises at
any time "For Sale"  signs,  (v) placing on the  Premises  ordinary  "For Lease"
signs  at any  time  within  one  hundred  eighty  (180)  days  prior  to  Lease
Termination,  or at any time Tenant is in uncured default hereunder,  or at such
other times as agreed to by Landlord and Tenant, (vi) protecting the Premises in
the event of an  emergency,  and (vii)  exhibiting  the Premises to  prospective
purchasers or lenders at any reasonable  time or to  prospective  tenants within
one hundred  eighty  (180) days prior to Lease  Termination.  In the event of an
emergency, Landlord shall have the right to use any and all means which Landlord
reasonably  may deem  proper to gain  access to the  Premises.  Any entry to the
Premises by Landlord or Landlord's  agents in accordance  with this Paragraph 18
or any other  provision  of this  Lease  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 of Tenant from the Premises or any portion thereof
nor give Tenant the right to abate the Rentals payable under this Lease.  Except
to the extent caused by the  negligence or willful  misconduct of Landlord,  its
agents, employees,  contractors or invitees, Tenant hereby waives any claims for
damages  for any  injury  or  inconvenience  to or  interference  with  Tenant's
business,  any loss of occupancy or quiet  enjoyment  of the  Premises,  and any
other  loss  occasioned  by  Landlord's  or  Landlord's  agents'  entry into the
premises as permitted by this Paragraph 18 or any other provision of this Lease.
Notwithstanding  anything to the contrary contained in this Lease,  Landlord and
Landlord's  agents,  except in the case of emergency,  shall provide Tenant with
twenty-four  (24) hours'  notice  prior to entry of the  Premises.  Any entry by
Landlord and Landlord's  agents shall not impair  Tenant's  operations more than
reasonably  necessary,  and  Tenant  shall  have the  right to have an  employee
accompany Landlord at all times that Landlord is present on the Premises.

         19. Landlord's Right to Perform Tenant's Covenants. Except as otherwise
expressly  provided herein, if Tenant shall at any time fail to make any payment
or perform any other act  required to be made or  performed by Tenant under this
Lease,  Landlord may upon ten (10) days written notice to Tenant,  but shall not
be obligated  to and without  waiving or  releasing  Tenant from any  obligation
under this Lease, make such payment or perform such other act to the extent that
Landlord  may deem  desirable,  and in  connection  therewith,  pay expenses and
employ  counsel.  All  reasonable  sums so paid by Landlord  and all  penalties,
interest and reasonable  costs in connection  therewith shall be due and payable
by Tenant as Additional Rent upon demand.


         20.  Lender Requirements.

              20..l  Subordination.  This Lease, at Landlord's option,  shall be
subject  and  subordinate  to the  lien  of any  mortgages  or  deeds  of  trust
(including  all  advances  thereunder,  renewals,  replacements,  modifications,
supplements, consolidations, and extensions thereof) in any amount(s) whatsoever
now or hereafter  placed on or against or affecting the Premises and/or the real
property  comprising the Common Area or Landlord's  interest or estate  therein,
without the necessity of the  execution and delivery of any further  instruments
on the part of Tenant to  effectuate  such  subordination.  If any  mortgagee or
beneficiary  shall elect to have this Lease prior to the lien of its mortgage or
deed of trust, and shall give written notice thereof to Tenant, this Lease shall
be deemed prior to such  mortgage or deed of trust,  whether this Lease is dated
prior or subsequent to the date of such mortgage or deed of trust or the date of
the recording thereof.

              20..2 Subordination  Agreements.  Tenant shall execute and deliver
without charge therefor,  such further instruments  evidencing  subordination of
this Lease to the lien of any mortgages or deeds of trust affecting the Premises
and/or real property  comprising  the Common Area as may be required by Landlord
within ten (10) days following  Landlord's request therefor;  provided that such
mortgagee or beneficiary  under such mortgage or deed of trust agrees in writing
that this Lease shall not be  terminated  or modified in any material way in the
event of any  foreclosure if Tenant is not in default under this Lease.  Failure
of Tenant to execute such  instruments  evidencing  subordination  of this Lease
shall constitute a Default by Tenant hereunder.

              20..3 Approval by Lenders.  Tenant  recognizes that the provisions
of this Lease may be subject to the approval of any financial  institution  that
may  make a loan  secured  by a new or  subsequent  deed of  trust  or  mortgage
affecting the Premises  and/or real property  comprising the Common Area. If the
financial  institution  should require,  as a condition to such  financing,  any
modifications  of this Lease in order to protect  its  security  interest in the
Premises, including without limitation,  modification of the provisions relating
to damage to and/or condemnation of the Premises,  Tenant agrees to negotiate in
good faith with  Landlord and such  financial  institution  to agree on mutually
acceptable  modifications  and execute  the  appropriate  amendments;  provided,
however,  that no modification shall substantially  change the size, location or
dimension of the Premises,  or increase the Rentals payable by Tenant hereunder.
If Tenant  refuses to execute any such  amendment,  Landlord  may, in Landlord's
reasonable discretion,  terminate this Lease. 

              20..4  Attornment.  In the event of foreclosure or the exercise of
the power of sale  under any  mortgage  or deed of trust  made by  Landlord  and
covering the Premises  and/or real property  comprising the Common Area,  Tenant
shall attorn to the purchaser  upon any such  foreclosure  or sale and recognize
such  purchaser  as the  Landlord  under this  Lease,  provided  such  purchaser
expressly  agrees in writing  to be bound by the terms of the Lease,  including,
but not limited  to, the quiet  enjoyment  provisions  of  Paragraph  39. 

              20..5  Estoppel  Certificates  and  Financial  Statements.   

                     (a)  Delivery  by  Tenant.  Tenant  shall,  within ten (10)
business days following request by Landlord therefor and without charge, execute
and  deliver to  Landlord  any and all  documents,  estoppel  certificates,  and
current  financial  statements  of Tenant  reasonably  requested  by Landlord in
connection  with the sale or  financing  of the  Premises  and/or real  property
comprising  the Common Area, or requested by any lender making a loan  affecting
the Premises  and/or real  property  comprising  the Common  Area.  Landlord may
require  that Tenant in any  estoppel  certificate  shall (i) certify  that this
Lease is  unmodified  and in full force and effect (or, if  modified,  state the
nature of such  modification and certify that this Lease, as so modified,  is in
full force and effect) and has not been assigned, (ii) certify the date to which
Rentals are paid in advance,  if any, (iii)  acknowledge  that there are not, to
Tenant's knowledge,  any uncured defaults on the part of Landlord hereunder,  or
specify such defaults if claimed,  (iv) evidence the status of this Lease as may
be required either by a lender making a loan to Landlord to be secured by a deed
of trust or mortgage  covering the Premises and/or real property  comprising the
Common Area or a purchaser of the Premises  and/or real property  comprising the
Common Area from Landlord,  (v) warrant that in the event any beneficiary of any
security instrument encumbering the Premises and/or real property comprising the
Common Area  forecloses on the security  instrument or sells the Premises and/or
real property comprising the Common Area pursuant to any power of sale contained
in such  security  instrument,  such  beneficiary  shall not be  liable  for the
Security Deposit,  unless the Security Deposit actually has been received by the
beneficiary  from Landlord,  (vi) certify the date Tenant entered into occupancy
of the Premises and that Tenant is conducting  business at the  Premises,  (vii)
certify that all improvements to be constructed on the Premises by Landlord have
been  substantially  completed  except for punch list items which do not prevent
Tenant from using the  Premises for its  intended  use, and (viii)  certify such
other  matters  relating  to the  Lease  and/or  Premises  as may be  reasonably
requested  by a lender  making a loan to Landlord or a purchaser of the Premises
and/or real property comprising the Common Area from Landlord. Any such estoppel
certificate  may be  conclusively  relied upon by any  prospective  purchaser or
encumbrancer  of the Premises  and/or real property  comprising the Common Area.
Any  financial  statements  of Tenant  shall  include an opinion of a  certified
public  accountant  (if  available)  and a  balance  sheet and  profit  and loss
statement for the most recent fiscal year,  or a reasonable  substitute  for the
form of such financial  information,  all prepared in accordance  with generally
accepted accounting principles consistently applied.

                     (b) Nondelivery by Tenant.  Tenant's  failure to deliver an
estoppel  certificate as required  pursuant to Paragraph  20.5(a) above shall be
conclusive upon Tenant that (i) this Lease is in full force and effect,  without
modification except as may be represented by Landlord and has not been assigned,
(ii) there are now no  uncured  defaults  in  Landlord's  performance,  (iii) no
Rentals have been paid in advance except those that are set forth in this Lease,
(iv) no beneficiary of any security  instrument  encumbering the Premises and/or
real  property  comprising  the Common  Area  shall be liable  for the  Security
Deposit in the event of a foreclosure  or sale under such  security  instrument,
unless the Security  Deposit  actually has been received by the beneficiary from
Landlord,  (v) the  improvements  to be  constructed on the Premises by Landlord
have been  substantially  completed  except for punch  list  items  which do not
prevent  Tenant from using the Premises for its intended use and (vi) Tenant has
entered into  occupancy of the  Premises on such date as may be  represented  by
Landlord and is open and conducting  business at the Premises.  Tenant's failure
to deliver any financial statements, estoppel certificates or other documents as
required pursuant to Paragraph 20.5(a) above shall be a Default by Tenant.

         21. Holding Over. This Lease shall terminate  without further notice at
the  expiration of the Lease Term. It is the desire of Landlord  either to enter
into a new lease with Tenant for the  Premises  prior to the  expiration  of the
Lease Term, or to have Tenant  vacate the Premises upon  expiration of the Lease
Term pursuant to Paragraph 35 below. Therefore, any holding over by Tenant after
Lease Termination shall not constitute a renewal or extension of the Lease Term,
nor give Tenant any rights in or to the Premises except as expressly provided in
this  Lease.  Any  holding  over after  Lease  Termination  with the  consent of
Landlord shall be construed to be a tenancy from month to month,  at one hundred
fifty  percent  (150%)  of the  monthly  Rent  for  the  month  preceding  Lease
Termination  in addition to all  Additional  Rent payable  hereunder,  and shall
otherwise be on the terms and conditions herein specified insofar as applicable.
If Tenant remains in possession of the Premises after Lease Termination  without
Landlord's  consent,  Tenant shall indemnify,  defend and hold Landlord harmless
from and against any loss, damage,  expense,  claim or liability  resulting from
Tenant's failure to surrender the Premises,  including without  limitation,  any
claims made by any succeeding  tenant based on delay in the  availability of the
Premises.

         22.  Notices.  Any notice  required  or desired to be given  under this
Lease shall be in writing,  and all notices shall be given by personal  delivery
or  mailing.  All notices  personally  given on Tenant may be  delivered  to any
person  apparently in charge at the Premises,  on any corporate officer or agent
of Tenant if Tenant is a corporation, or on any one signatory party if more than
one party  signs this Lease on behalf of  Tenant;  any notice so given  shall be
binding upon all signatory parties as if served upon each such party personally.
Any notice  given  pursuant  to this  Paragraph  22 shall be deemed to have been
given when personally delivered, or if mailed, when three (3) business days have
elapsed from the time when such notice was  deposited in the United States mail,
certified or registered mail and postage prepaid,  addressed to the party at the
last address  given for purposes of notice  pursuant to the  provisions  of this
Paragraph 22. At the date of execution of this Lease,  the addresses of Landlord
and Tenant are set forth in Paragraph 1.11 above.

         23.  Attorneys'  Fees. In the event either party hereto shall bring any
action or legal proceeding for damages for an alleged breach of any provision of
this Lease, to recover Rentals, to enforce an indemnity defense or hold harmless
obligation,  to terminate the tenancy of the Premises,  or to enforce,  protect,
interpret,  or establish any term, condition, or covenant of this Lease or right
or remedy of either party, the prevailing party shall be entitled to recover, as
a part of such action or proceeding, reasonable attorneys' fees and court costs,
including  reasonable  attorneys' fees and costs for appeal,  as may be fixed by
the court or jury.  Notwithstanding  anything to the contrary  contained in this
Lease,  "prevailing party" as used in this paragraph shall include the party who
dismisses an action for recovery  hereunder in exchange for sums  allegedly due,
performance  of covenants  allegedly  breached or  considerations  substantially
equal to the relief sought in the action.

         24.  Assignment, Subletting and Hypothecation  
                        
              24..1 In General.  Tenant shall not  voluntarily  sell,  assign or
transfer  all or any part of Tenant's  interest in this Lease or in the Premises
or any part thereof,  sublease all or any part of the Premises, or permit all or
any part of the Premises to be used by any person or entity other than Tenant or
Tenant's employees, except as specifically provided in this Paragraph 24.

              24..2 Voluntary Assignment and Subletting.

                    (a) Notice to Landlord.  Tenant  shall,  by written  notice,
advise  Landlord  of  Tenant's  desire on a stated date (which date shall not be
less than  fifteen  (15) days nor more than  ninety  (90) days after the date of
Tenant's  notice)  to  assign  this  Lease or to  sublet  all or any part of the
Premises for any part of the Lease Term. Said notice shall state that the notice
constitutes an offer to terminate the Lease pursuant to Paragraph 24.2(b) if the
notice  applies  to a  proposed  assignment  of the Lease or  Tenant's  interest
herein.  Tenant's notice shall state the name, legal  composition and address of
the  proposed  assignee or  subtenant,  and Tenant shall  provide the  following
information  to  Landlord  with said  notice:  a true and  complete  copy of the
proposed assignment  agreement or sublease a financial statement of the proposed
assignee or subtenant prepared in accordance with generally accepted  accounting
principles  within  one  year  prior  to  the  proposed  effective  date  of the
assignment or sublease;  the nature of the proposed  assignee's  or  subtenant's
business  to be carried on in the  Premises;  the  payments  to be made or other
consideration  to be given on account of the  assignment or sublease;  a current
financial  statement of Tenant;  and such other pertinent  information as may be
requested by Landlord,  all in sufficient  detail to enable Landlord to evaluate
the proposed  assignment or sublease and the prospective  assignee or subtenant.
Tenant's notice shall not be deemed to have been served or given until such time
as Tenant has provided  Landlord with all  information  reasonably  requested by
Landlord  pursuant to this  Paragraph  24.2.  Tenant  shall  immediately  notify
Landlord  of any  modification  to the  proposed  terms  of such  assignment  or
sublease.  Tenant may withdraw its notice at any time prior to or after exercise
by Landlord of Landlord's right to terminate as described in Paragraph 24.2(b).

                    (b) Offer to Terminate.  If Tenant notifies  Landlord of its
desire to assign this Lease or Tenant's  interest herein,  Tenant's notice shall
constitute an offer to terminate  this Lease and Landlord  shall have the right,
to be exercised by giving  written  notice to Tenant  within  fifteen (15)  days
after receipt of Tenant's notice,  to terminate the Lease. If Landlord elects to
terminate,  then  within ten (10) days after  receipt  of  Landlord's  election,
Tenant  shall have the right to rescind  its  request to assign,  and this Lease
shall continue in full force and effect. If Tenant does not rescind its request,
this Lease  shall  terminate  on the date  stated in the notice  given by Tenant
pursuant to Paragraph 24.2(a), subject to any obligations which have accrued and
are  unfulfilled as of such date. 

                    (c)  Landlord's  Consent.  If Landlord does not exercise its
right to terminate  pursuant to Paragraph 24.2(b) within fifteen (15) days after
receipt of Tenant's notice or if Tenant proposes a sublease,  Landlord shall not
unreasonably  withhold  or delay  its  consent  to the  proposed  assignment  or
subletting,  on the terms and conditions  specified in said notice.  If Tenant's
notice fails to state that it constitutes an offer to terminate the Lease as may
be  required  pursuant  to  Paragraph  24.2(a),  such  notice  shall  be  deemed
insufficient  for the purposes of this Paragraph 24.2, and Landlord may withhold
its  consent to the  proposed  assignment  in  Landlord's  absolute  discretion.
Without  otherwise  limiting the criteria  upon which  Landlord may withhold its
consent to any  proposed  assignment  or  sublease,  if Landlord  withholds  its
consent where Tenant is in default at the time of the giving of Tenant's  notice
or at any time  thereafter,  or where  the net  worth of the  proposed  assignee
(according to generally accepted accounting principles) is less than the greater
of (i) the net worth of Tenant  immediately  prior to the assignment (ii) or the
net worth of Tenant at the time this  Lease is  executed,  such  withholding  of
consent shall be  presumptively  reasonable.  Fifty percent (50%) of any and all
rent paid by an assignee or  subtenant in excess of the Rentals to be paid under
this  Lease  (prorated  in the  event of a  sublease  of less  than  the  entire
Premises),  after Tenant's deduction therefrom of all reasonable costs to effect
the  assignment  or  subletting,   including   without   limitation,   brokerage
commissions,  attorneys'  fees,  and  the  cost  of  leasehold  improvements  or
alterations  installed or  redecorating  performed by Tenant for the  sublessee,
shall be paid directly to Landlord,  as  Additional  Rent, at the time and place
specified in this Lease.  For the purposes of this Paragraph 24, the term "rent"
shall include any  consideration  of any kind  received,  or to be received,  by
Tenant  from an  assignee  or  subtenant,  if such sums are  related to Tenant's
interest  in this Lease or in the  Premises,  including,  but not limited to key
money,  bonus money,  and payments (in excess of the fair market value  thereof)
for Tenant's assets, fixtures, trade fixtures,  inventory,  accounts,  goodwill,
equipment, furniture, general intangibles, and any capital stock or other equity
ownership  interest of Tenant.  Any assignment or subletting  without Landlord's
consent shall be voidable at Landlord's  option,  and shall constitute a Default
by  Tenant.  Landlord's  consent to any one  assignment  or  sublease  shall not
constitute a waiver of the  provisions of this Paragraph 24 as to any subsequent
assignment  or sublease nor a consent to any  subsequent  assignment or sublease
further,  Landlord's  consent to an  assignment  or  sublease  shall not release
Tenant from  Tenant's  obligations  under this Lease,  and Tenant  shall  remain
jointly and severally liable with the assignee or subtenant.

                    (d)  Assumption  of  Obligations.   In  the  event  Landlord
consents to any assignment,  such consent shall be conditioned upon the assignee
expressly  assuring  and  agreeing  to be bound by each of  Tenant's  covenants,
agreements  and  obligations  contained  in this  Lease,  pursuant  to a written
assignment and assumption  agreement in a form reasonably  approved by Landlord.
Landlord's  consent  to  any  assignment  or  sublease  shall  be  evidenced  by
Landlord's  signature on said  assignment  and  assumption  agreement or on said
sublease or by a separate written consent.  In the event Landlord  consents to a
proposed assignment or sublease,  such assignment or sublease shall be valid and
the  assignee  or  subtenant  shall  have the  right to take  possession  of the
Premises only if an executed original of the assignment or sublease is delivered
to Landlord,  and such document contains the same terms and conditions as stated
in Tenant's notice to Landlord given pursuant to Paragraph 24.2(a) above, except
for any such modifications to which Landlord has consented in writing.

              24..3 Collection of Rent.  Tenant hereby  irrevocably gives to and
confers upon Landlord,  as security for Tenant's  obligations  under this Lease,
the right,  power and  authority  to  collect  all rents  from any  assignee  or
subtenant of all or any part of the Premises as permitted by this  Paragraph 24,
or  otherwise,  and  Landlord,  as assignee of Tenant,  or a receiver for Tenant
appointed on Landlord's  application,  may collect such rent and apply it toward
Tenant's  obligations  under  this  Lease;  provided,  however,  that  until the
occurrence  of any Default by Tenant,  subject to applicable  cure  periods,  or
except as provided by the provisions of Paragraph  24.2(c)  above,  Tenant shall
have the right to  collect  such rent.  Upon the  occurrence  of any  Default by
Tenant,  Landlord may at any time without  notice in Landlord's own name sue for
or otherwise  collect such rent,  including rent past due and unpaid,  and apply
the same,  less  costs and  expenses  of  operation  and  collection,  including
reasonable  attorneys'  fees,  toward  Tenant's  obligations  under this  Lease.
Landlord's  collection  of such rents  shall not  constitute  an  acceptance  by
Landlord of attornment by such subtenants.  In the event of a Default by Tenant,
Landlord  shall have all rights  provided by this Lease and by law, and Landlord
may, upon re-entry and taking  possession of the Premises,  eject all parties in
possession  or eject some and not  others,  or eject  none,  as  Landlord  shall
determine in Landlord's sole discretion.  

              24..4  Corporations and Partnerships.  If Tenant is a partnership,
any withdrawal or substitution (whether voluntary,  involuntary, or by operation
of law and  whether  occurring  at one  time or over a  period  of  time) of any
partner(s) owning fifty percent (50%) or more (cumulatively) of the partnership,
any assignment(s) of fifty percent (50%) or more  (cumulatively) of any interest
in the  capital  or  profits  of the  partnership,  or  the  dissolution  of the
partnership  shall be deemed an  assignment  of this Lease  requiring  the prior
written  consent  of  Landlord.  If Tenant is a  corporation,  any  dissolution,
merger,  consolidation or other  reorganization of Tenant,  any sale or transfer
(or  cumulative  sales or transfers) of the capital stock of Tenant in excess of
fifty percent (50%),  or any sale (or cumulative  sales) of all of the assets of
Tenant shall be deemed an assignment  of this Lease  requiring the prior written
consent  of  Landlord.  Any such  withdrawal  or  substitution  of  partners  or
assignment of any  interest in or dissolution of a partnership  tenant,  and any
such sale of stock or assets of a corporate  tenant  without  the prior  written
consent  of  Landlord  shall be a Default  by Tenant  hereunder.  The  foregoing
notwithstanding,  the sale or transfer  of any or all of the capital  stock of a
corporation,  the capital  stock of which is now or hereafter  becomes  publicly
traded,  shall  not be  deemed  an  assignment  of this  Lease.  

              Notwithstanding  anything to the contrary contained in this Lease,
Tenant,  without Landlord's prior written consent (but with notice to Landlord),
may sublet the  Premises  or assign this Lease to (i) a  subsidiary,  affiliate,
division or corporation  controlled by or under common control with Tenant; (ii)
a   successor   corporation   related  to  Tenant  by   merger,   consolidation,
non-bankruptcy  reorganization  or  government  action;  or (iii) a purchaser of
substantially  all of Tenant's assets located at the Premises,  provided that in
either of the latter two  instances  the  successor or purchaser has a net worth
not less than the net worth of Tenant at the tinge  that  Tenant  executes  this
Lease (each, a "Permitted Assignee"). Notwithstanding that a Transfer is made to
a Permitted  Assignee,  Tenant shall not be released from any of its obligations
under this Lease and such Permitted  Assignee shall be required to assume all of
Tenant's  obligations  hereunder as a condition to such transfer being permitted
without Landlord's prior written consent.  

              24..5  Reasonable  Provisions.  Tenant  expressly  agrees that the
provisions of this Paragraph 24 are not unreasonable standards or conditions for
purposes of Section  1951.4(b)(2) of the California  Civil Code, as amended from
time to time, under bankruptcy laws, or for any other purpose.
              
              24..6  Attorneys'  Fees.  Tenant  shall pay, as  Additional  Rent,
Landlord's  reasonable attorneys fees for reviewing,  investigating,  processing
and/or  documenting  any  requested  assignment  or  sublease,  whether  or  not
Landlord's  consent is  granted.  

              24..7  Involuntary  Transfer.  No interest of Tenant in this Lease
shall be assignable,  involuntarily or by operation of law,  including,  without
limitation,  the  transfer  of this Lease by testacy or  intestacy.  Each of the
following acts shall be considered an involuntary assignment:

                    (a) If  Tenant is or becomes bankrupt or insolvent, makes an
assignment  for the benefit of creditors,  or a proceeding  under any bankruptcy
law is  instituted  in  which  Tenant  is  the  bankrupt;  or,  if  Tenant  is a
partnership or consists of more than one person or entity, if any partner of the
partnership  or other person or entity is or becomes  bankrupt or insolvent,  or
makes an assignment for the benefit of creditors;

                    (b) Levy of a writ of attachment or execution on this Lease;

                    (c) Appointment  of  a   receiver  with  authority  to  take
possession  of the  Premises in any  proceeding  or action to which  Tenant is a
party; or

                    (d) Foreclosure  of any lien affecting  Tenant's interest in
the Premises,  which lien was not consented to by Landlord pursuant to Paragraph
24.9.

An  involuntary  assignment  shall  constitute  a Default by Tenant and Landlord
shall have the right to terminate this Lease, in which case this Lease shall not
be treated as an asset of Tenant. In the event the Lease is not terminated,  the
provisions of Paragraph 24.2(c) regarding rents paid by an assignee or subtenant
shall apply. If a writ of attachment or execution is levied on this Lease, or if
any involuntary proceeding in bankruptcy is brought against Tenant or a receiver
is appointed, Tenant shall have sixty (60) days in which to cause the attachment
or  execution  to be  removed,  the  involuntary  proceeding  dismissed,  or the
receiver removed.

              24..8  Hypothecation.  Tenant shall not  hypothecate,  mortgage or
encumber  Tenant's  interest in  this Lease or in the Premises or otherwise  use
this Lease as a security  device in any manner  without the consent of Landlord,
which consent Landlord may withhold in its sole and absolute discretion. Consent
by Landlord to any such  hypothecation  or creation of a lien or mortgage  shall
not  constitute  consent  to an  assignment  or  other  transfer  of this  Lease
following foreclosure of any  permitted lien or mortgage.

              24..9 Binding on  Successors.  The provisions of this Paragraph 24
expressly apply to all heirs, successors,  sublessees, assignees and transferees
of Tenant.

         25.  Successors.  Subject to the  provisions  of Paragraph 24 above and
Paragraph 30.2(a) below, the covenants,  conditions, and agreements contained in
this Lease shall be binding on the parties hereto and on their respective heirs,
successors and assigns.

         26. Landlord  Default;  Mortgage  Protection.  Landlord shall not be in
default under this Lease unless Tenant shall have given Landlord  written notice
of the breach and, within thirty (30) days after notice,  Landlord has not cured
the breach or, if the breach is such that it cannot  reasonably  be cured  under
the  circumstances  within  thirty (30) days,  has not  commenced  diligently to
prosecute the cure to completion.  Any money  judgment  obtained by Tenant based
upon Landlord's breach of this Lease shall be satisfied only out of the proceeds
of the sale or  disposition of Landlord's  interest in the Premises  (whether by
Landlord or by execution of  judgment).  In the event of any default on the part
of  Landlord  under this  Lease,  Tenant  shall  give  notice by  registered  or
certified  mail to any  beneficiary  of a deed of  trust or any  mortgagee  of a
mortgage  affecting the Premises and/or the real property  comprising the Common
Area whose  address  shall have been  furnished to Tenant,  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  judicial
foreclosure, if such should prove necessary to effect a cure.

         27. Exhibits. All exhibits attached to this Lease shall be deemed to be
incorporated  herein by the individual  reference to each such exhibit,  and all
such exhibits  shall be deemed to be a part of this Lease as though set forth in
full in the body of the Lease.

         28. Surrender of Lease Not Merger.  The voluntary or other surrender of
this Lease by Tenant, or a mutual cancellation thereof,  shall not work a merger
and shall, at the option of Landlord, terminate all or any existing subleases or
subtenants,  or may,  at the option of  Landlord,  operate as an  assignment  to
Landlord of any or all such subleases or subtenants.

         29. Waiver. The waiver by Landlord of any breach of any term,  covenant
or condition  herein contained (or the acceptance by Landlord of any performance
by Tenant  after the time the same shall become due) shall not be deemed to be a
waiver of such term,  covenant or condition or any subsequent  breach thereof or
of any other term,  covenant or condition  herein  contained,  unless  otherwise
expressly  agreed to by Landlord in writing.  The  acceptance by Landlord of any
sum less than that  which is  required  to be paid by Tenant  shall be deemed to
have been  received only on account of the  obligation  for which it is paid (or
for which it is allocated by Landlord, in Landlord's reasonable  discretion,  if
Tenant does not  designate  the  obligation  as to which the  payment  should be
credited),  and shall not be deemed an accord and  satisfaction  notwithstanding
any  provisions to the contrary  written on any check or contained in any letter
of  transmittal.  The  acceptance by Landlord of any sum tendered by a purported
assignee or  transferee  of Tenant  shall not be deemed a consent by Landlord to
any assignment or transfer of Tenant's  interest  herein.  No custom or practice
which may arise between the parties hereto in the administration of the terms of
this Lease shall be construed as a waiver or diminution  of Landlord's  right to
demand performance by Tenant in strict accordance with the terms of this Lease.

         30.  General.

              30..1 Captions and Headlines. The captions and paragraph headings
used in this Lease are for  convenience  of  reference  only.  They shall not be
construed  to limit or extend the meaning of any part of this  Lease,  and shall
not  be  deemed  relevant  in  resolving  any  question  of   interpretation  or
construction of any paragraph of this Lease.

              30..2  Definitions.

                     (a) Landlord.  The term Landlord as used in this Lease,  so
far as the covenants or obligations on the part of Landlord are concerned, shall
be limited to mean and include only the owner at the time in question of the fee
title to the Premises.  In the event of any  transfer(s) of such  interest,  the
Landlord  herein named (and in case of any subsequent  transfers or conveyances,
the then  grantor)  shall have no further  liability  under this Lease to Tenant
except as to matters of liability  which have accrued and are  unsatisfied as of
the date of such transfer,  it being intended that the covenants and obligations
contained in this Lease on the part of Landlord shall be binding on Landlord and
its  successors  and  assigns  only  during and in  respect of their  respective
periods of  ownership of the fee provided  that any funds in the  possession  of
Landlord or the then grantor and as to which  Tenant has an  interest,  less any
deductions  permitted by law or this Lease, shall be turned over to the grantee.
The  covenants and  obligations  contained in this Lease on the part of Landlord
shall, subject to the provisions of this Paragraph 30.2(a), be binding upon each
Landlord and such Landlord's  heirs,  personal  representatives,  successors and
assigns only during its  respective  period of ownership.  Except as provided in
this  Paragraph  30.2(a),  this Lease shall not be  affected by any  transfer of
Landlord's  interest in the Premises,  and Tenant shall attorn to any transferee
of Landlord provided that all of Landlord's obligations hereunder are assumed in
writing by such transferee.

                     (b)  Agents.   For  purposes  of  this  Lease  and  without
otherwise  affecting  the  definition  of the word  "agent" or the meaning of an
"agency",  the term "agents"  shall be deemed to include the agents,  employees,
officers,    directors,    servants,    invitees,    contractors,    successors,
representatives   subcontractors,   guests,  customers,   suppliers,   partners,
affiliated  companies,  and any other person or entity related in any way to the
respective party, Tenant or Landlord.

                     (c)  Interpretation  of  Terms.  The words  "Landlord"  and
"Tenant" as used herein shall include the plural as well as the singular.  Words
in the  neuter  gender  include  the  masculine  and  feminine  and words in the
masculine or feminine gender include the neuter.

              30..3  Copies.  Any executed copy of this Lease shall be deemed an
original for all purposes.

              30..4 Time of Essence. Time is of the essence as to each and every
provision in this Lease requiring performance within a specified time.

              30..5  Severabilitv.  In case  any  one or more of the  provisions
contained  herein  shall  for  any  reason  be held to be  invalid,  illegal  or
unenforceable in any respect,  such invalidity,  illegality or  unenforceability
shall not affect any other  provision  of this  Lease,  but this Lease  shall be
construed as if such invalid,  illegal or  unenforceable  provision had not been
contained  herein.  However,  if  Tenant's  obligation  to pay  the  Rentals  is
determined to be invalid or unenforceable,  this Lease at the option of Landlord
shall terminate.

              30..6 Governing Law. This Lease shall be construed and enforced in
accordance with the laws of the State of California.

              30..7  Joint  and  Several  Liability.  If Tenant is more than one
person or entity,  each such  person or entity  shall be jointly  and  severally
liable for the obligations of Tenant hereunder. If Tenant is a husband and wife,
the obligations  hereunder  shall extend to their sole and separate  property as
well as community property.

              30..8   Construction  of  Lease   Provisions.   Although   printed
provisions  of this Lease were  prepared  by  Landlord,  this Lease shall not be
construed  either for or against  Tenant or Landlord,  but shall be construed in
accordance  with the general tenor of the language to reach a fair and equitable
result.

              30..9 Tenant's Financial  Statements.  Tenant hereby warrants that
all financial  statements delivered by Tenant to Landlord are true, correct, and
complete,   and  prepared  in  accordance  with  generally  accepted  accounting
principles.  Tenant  acknowledges  and agrees  that  Landlord is relying on such
financial  statements  in  accepting  this Lease,  and that a breach of Tenant's
warranty as to such financial  statements  shall constitute a Default by Tenant.
Notwithstanding anything to the contrary contained in this Lease, Landlord shall
keep confidential all such financial  information  received from Tenant,  except
that Landlord may provide such financial  information  to Landlord's  lenders or
prospective lenders with respect to the Premises.

              30..10  Withholding  of Landlord's  Consent.  Notwithstanding  any
other  provision  of this Lease,  where Tenant is required to obtain the consent
(whether  written or oral) of  Landlord  to do any act,  or to refrain  from the
performance of any act,  Tenant agrees that if Tenant is in default with respect
to any term, condition, covenant or provision of this Lease, then Landlord shall
be deemed to have acted  reasonably in  withholding  its consent if said consent
is, in fact,  withheld.  

         31.  Signs  Tenant  shall not place or permit to be placed  any sign or
decoration  on the Common Area or the  exterior of the Premises or that would be
visible from the exterior of the Premises,  without the prior written consent of
Landlord,  which consent shall not be unreasonably  withheld or delayed.  Tenant
may place "for lease" signs in connection with efforts to assign or sublease the
Premises,  subject to the prior written consent of Landlord, which consent shall
not be unreasonably  withheld or delayed;  provided that all such signs shall be
removed  not later than the one  hundred  eightieth  (180th)  day prior to Lease
Termination. In no event shall any such sign revolve, rotate, move or create the
illusion of revolving, rotating or moving or be internally illuminated and there
shall be no  exterior  spotlighting  or  other  illumination  on any such  sign.
Tenant,  upon  written  notice by  Landlord,  shall  immediately  remove  any of
Tenant's signs or decorations that are visible from the exterior of the Premises
or that  Tenant has placed or  permitted  to be placed on the Common Area or the
exterior of the Premises without the prior written consent of Landlord, or which
remain beyond the one hundred eightieth (180th) day prior to Lease  Termination.
If Tenant fails to so remove such sign or decoration  within five (5) days after
Landlord's written notice,  Landlord may enter the Premises and remove such sign
or decoration and Tenant shall pay Landlord, as Additional Rent upon demand, the
cost of such removal.  All signs placed on the Premises or Common Area by Tenant
shall comply with all recorded documents  affecting the Premises,  including but
not limited to any Declaration of Conditions,  Covenants and  Restrictions:  the
sign criteria  attached  hereto as Exhibit E, if applicable  (as the same may be
amended  from time to time);  and  applicable  statutes,  ordinances,  rules and
regulations of governmental  agencies having jurisdiction thereof. At Landlord's
option, Tenant shall at Lease Termination remove any sign which it has placed on
the Premises or the Common Area, and shall, at its sole cost,  repair any damage
caused by the installation or removal of such sign.

         32. Landlord as Party  Defendant.  If, by reason of any act or omission
by Tenant or Tenant's agents, Landlord is made a party defendant concerning this
Lease, the Premises, or the Common Area, Tenant shall indemnify Landlord against
all liability  actually  incurred (or  threatened  against)  Landlord as a party
defendant, including all damages, costs and reasonable attorneys' fees.

         33.  Landlord  Not a  Trustee.  Landlord  shall  not be  deemed to be a
trustee of any funds paid to Landlord by Tenant (or held by Landlord for Tenant)
pursuant to this Lease,  including  without  limitation  the  Security  Deposit.
Landlord shall not be required to keep any such funds  separate from  Landlord's
general funds. Any funds held by Landlord  pursuant to this Lease shall not bear
interest.

         34. Interest. Any payment due from Tenant to Landlord,  except for Rent
received by Landlord  within thirty (30) days after the same is due,  shall bear
interest  from the date due until  paid,  at an annual rate equal to the greater
of: ten percent  (10%);  or five percent (5%) plus the rate  established  by the
Federal Reserve Bank of San Francisco, as of the twenty-fifth (25th)  day of the
month  immediately  preceding  the due date,  on advances to member  banks under
Sections 13 and 13(a) of the Federal  Reserve Act, as now in effect or hereafter
from  time to time  amended.  In  addition,  Tenant  shall  pay  all  costs  and
reasonable  attorneys'  fees  incurred  by Landlord  in the  collection  of such
amounts.

         35.  Surrender of  Premises.  On the last day of the Lease Term or upon
the  sooner  termination  of  this  Lease,   Tenant  shall,  to  the  reasonable
satisfaction  of Landlord,  surrender the Premises to Landlord in good condition
(reasonable  wear  and  tear,  acts of God,  casualty,  condemnation,  Hazardous
Materials  other than those stored,  used or disposed of by Tenant,  its agents,
employees,  contractors or invitees,  and alterations  concerning which Landlord
has not  reserved the right to require  removal  excepted)  with all  originally
painted  interior  walls washed,  or re-painted if marked or damaged,  and other
interior walls cleaned and repaired or replaced, all carpets cleaned and in good
condition,  the air conditioning,  ventilating and heating equipment  inspected,
serviced and repaired by a reputable and licensed  service firm (unless Landlord
has  elected to  maintain  heating  and air  conditioning  systems  pursuant  to
Paragraph 10. 1 above),  and all floors  cleaned and waxed.  Tenant shall remove
all of Tenant's personal property and trade fixtures from the Premises,  and all
property not so removed shall be deemed abandoned by Tenant. Furthermore, Tenant
shall  immediately  repair all damage to the  Premises and Common Area caused by
any such removal.  If the Premises are not so surrendered at Lease  Termination,
Tenant shall indemnify,  defend and hold Landlord  harmless from and against any
loss, damage,  expense,  claim or liability resulting from delay by Tenant in so
surrendering the Premises including,  without limitation, any claims made by any
succeeding  tenant or losses to Landlord due to lost  opportunities  to lease to
succeeding tenants.

         36. No  Partnership  or Joint  Venture.  Nothing in this Lease shall be
construed as creating a partnership or joint venture between  Landlord,  Tenant,
or any  other  party,  or cause  Landlord  to  be  responsible  for the debts or
obligations of Tenant or any other party.

         37. Entire Agreement.  Any agreements,  warranties,  or representations
not expressly  contained  herein shall in no way bind either Landlord or Tenant,
and Landlord and Tenant  expressly waive all claims for damages by reason of any
statement, representation, warranty, promise or agreement, if any, not contained
in  this  Lease.  This  Lease  supersedes  and  cancels  any  and  all  previous
negotiations,  arrangements,  brochures, agreements and understandings,  whether
written or oral,  between Landlord and its agents and Tenant and its agents with
respect to the Premises,  Common Area or this Lease.  This Lease constitutes the
entire agreement  between the parties hereto and no addition to, or modification
of, any term or provision of this Lease shall be effective  until and unless set
forth in a written instrument signed by both Landlord and Tenant.

         38.  Submission of Lease.  Submission of this  instrument  for Tenant's
examination  or  execution  does not  constitute a  reservation  of space nor an
option to lease.  This instrument  shall not be effective until executed by both
Landlord and Tenant. Execution of this Lease by Tenant shall constitute an offer
by  Tenant to lease the  Premises,  which  offer  shall be  deemed  accepted  by
Landlord when this Lease is executed by Landlord and delivered to Tenant.

         39. Quiet  Enjoyment.  Landlord  covenants  and agrees with Tenant that
upon Tenant paying Rentals and performing its covenants and conditions under the
Lease,  Tenant  shall and may  peaceably  and quietly  have,  hold and enjoy the
Premises for the Lease Term, subject, however, to the terms of this Lease and of
any mortgages or deeds of trust  affecting the Premises and/or the real property
comprising the Common Area, and the rights reserved by Landlord  hereunder.  Any
purchaser  upon any  foreclosure  or  exercise  of the  power of sale  under any
mortgage or deed of trust made by Landlord  and  covering  the  Premises to whom
Tenant  attorns  pursuant to Paragraph 20.4 above shall be bound by the terms of
this Paragraph 39.
