3. TERM.

(a)  Original  Term.  The term of this Lease  ("Original  Term") will be for the
period designated in subparagraph 1(i), commencing on the Commencement Date, and
ending  on the last day of the  month in which  the  expiration  of such  period
occurs,  including any  extensions of the Term pursuant to any provision of this
Lease or written agreement of the parties. Notwithstanding the foregoing, if the
Commencement  Date falls on any day other than the first day of a calendar month
then the Term of this  Lease  will be  measured  from the first day of the month
following  the month in which the  Commencement  Date occurs.  Each  consecutive
twelve  (12)  month  period  of  the  Term  of  this  Lease,  commencing  on the
Commencement  Date,  will be  referred to herein as a "Lease  Year".  Landlord's
Notice of Lease Term Dates and Tenant's  Percentage  ("Notice"),  in the form of
Exhibit "D" attached hereto, will set forth the Commencement Date, the date upon
which the Term of this Lease  shall end,  the  Rentable  Square  Feet within the
Premises  and the  Building,  and Tenant's  Percentage  and will be delivered to
Tenant after Landlord delivers  possession of the Premises to Tenant. The Notice
will be  binding  upon  Tenant  unless  Tenant  objects to the Notice in writing
within five (5) days of Tenant's receipt of the Notice.

(b) Extension.  Subject to the terms of this Paragraph 3, Landlord hereby grants
to Tenant one (1) option ("Extension  Option") to extend the original Term as to
the entire  Premises  only for an additional  period of five (5) years  ("Option
Term"), on the same terms, covenants and conditions as provided for in the Lease
for the original  Term,  except that the economic  Lease terms during the Option
Term  shall be as set  forth in this  Paragraph  3.

(c) Rent for Option Term.  Monthly Base Rent at the beginning of the Option Term
shall be adjusted to equal the "fair market"  determined based on the parameters
described in subparagraph 3(e) below;  provided,  however, in no event shall the
Monthly Base Rent be decreased  after such adjustment to an amount less than the
Monthly Base Rent payable in the month immediately preceding the Option Term.

                                      -3-
 24

(d) Exercise of Option.  The Extension  Option must be exercised,  if at all, by
written  notice  ("Extension  Notice")  delivered by Tenant to Landlord no later
than  the  date  which  is four  hundred  twenty-five  (425)  days  prior to the
expiration of the original Term.

(e)  Determination  of Monthly Base Rent.  The "fair  market"  determination  as
described  in this  Paragraph  3 shall mean the annual  amount per square  foot,
projected during the Option Term (including any applicable rent increases during
the Option Term), that a willing, comparable, renewal tenant (excluding sublease
and assignment transactions),  would pay and that a willing, comparable landlord
would accept for comparable  space in a comparable Class "A" building located in
the  City  of  Calabasas  or  Warner  Center  (the  "Comparison  Market  Area").
Comparable  space  shall  consist  of  such  space  of  comparable  quality  and
improvements  as are located  within the Building,  taking into account the age,
quality,  layout of the  Premises,  the parking  rights  available to Tenant and
Tenant's  Authorized Users, and also taking into account items that professional
real estate brokers  customarily  consider,  such as who is paying for taxes and
insurance,  rental rates, availability,  tenant size and other factors typically
considered  by  Landlord  or lessors of similar  facilities,  and shall  include
consideration  given  to  tenant  improvement  allowance,  free  rent  or  other
concessions but only to the extent such  concessions are generally  available to
renewal tenants in the Comparison Market Area.

(f) Tenant  Review Period and Election to Cancel  Exercise of Extension  Option.
Within  thirty  (30) days  following  Tenant's  due and timely  exercise  of the
Extension Option as provided herein,  Landlord shall provide Tenant with written
notice of Landlord's  good faith  determination  of fair market for the Premises
for the  applicable  Option Term  determined  by taking into account the matters
described  in  subparagraph  3(e) above.  Within  sixty (60) days  ("Negotiation
Period")  after receipt of Landlord's  notice of the fair market  determination,
Landlord  and Tenant  shall  meet in a good faith  effort to agree upon the fair
market for the  Premises  for the Option Term but without any  obligation  to so
agree.  If  Landlord  and Tenant  fail to reach  agreement  on such fair  market
determination  prior to the expiration of the  Negotiation  Period (the "Outside
Agreement  Date"),  then Tenant,  within five (5) days of the  expiration of the
Negotiation  Period,  may cancel and nullify the Extension  Option by delivering
written notice of such election to Landlord. In the event of Tenant's failure to
so elect to cancel and nullify  the  Extension  Option  within such five (5) day
period,   Landlord  and  Tenant  shall  submit  their   respective   good  faith
determinations  of fair market for the Premises for the relevant  period of time
to appraisal in accordance with the provisions below.

(g)  Appointment of  Appraisers.  Landlord and Tenant shall each appoint one (1)
independent,  unaffiliated appraiser who is by profession a licensed real estate
broker who has been active  over the five (5) year period  ending on the date of
such appointment in the leasing of office space located in the Comparison Market
Area. Each such appraiser shall be appointed  within fifteen (15) days after the
Outside  Agreement  Date.  If the two (2)  appraisers so appointed do not within
fifteen (15) days of the date of the appointment of the last appointed appraiser
agree upon  whether  Landlord's  or  Tenant's  last  submitted  (on the  Outside
Agreement Date) fair market determination,  then said appraisers within five (5)
days  thereafter  shall  agree upon and appoint a third  appraiser  who shall be
qualified  under the same  criteria  for  qualification  of the  initial two (2)
appraisers.

(h) Third  Appraiser.  The third appraiser  shall determine  whether the parties
shall use Landlord's or Tenant's last submitted (on the Outside  Agreement Date)
fair market  determination,  and shall notify Landlord and Tenant  thereof.  The
determination  of the third  appraiser  shall be limited  solely to the issue of
whether  Landlord's or Tenant's last submitted (on the Outside  Agreement  Date)
fair market determination is the closest to the actual fair market for such area
as  solely   determined  by  the  third  appraiser,   taking  into  account  the
requirements specified above. The decision of the third appraiser shall be final
and binding upon Landlord and Tenant.

(i) Failure to Appoint Appraiser.  If either Landlord or Tenant fails to appoint
an appraiser within the time period specified in subparagraph  3(g) hereinabove,
the appraiser appointed by one of them shall, within fifteen (15) days following
the date on which the party  failing  to appoint  an  appraiser  could have last
appointed such  appraiser,  reach a decision based upon the procedures set forth
above (i.e., by selecting  either  Landlord's or Tenant's last submitted [on the
Outside Agreement Date] fair market determination) and shall notify Landlord and
Tenant thereof,  and such  appraiser's  decision shall be final and binding upon
Landlord and Tenant.

                                      -4-
 25

(j) Failure to Appoint Third  Appraiser.  If the two (2) appraisers  selected by
Landlord  and Tenant  fail to agree upon and timely  appoint a third  appraiser,
both  appraisers  shall be  dismissed  and the  matter  to be  decided  shall be
forthwith  submitted  to  arbitration  under  the  provisions  of  the  American
Arbitration  Association  based upon the  procedures  set forth above (i.e.,  by
selecting either Landlord's or Tenant's last submitted [on the Outside Agreement
Date] fair market determination).

(k) Delay In Determination of Fair Market Rent. If the process described in this
Paragraph 3 has not  resulted  in a selection  of  Landlord's  or Tenant's  fair
market  determinations  by the commencement of the applicable  Option Term, then
the average of the fair market  determinations  estimated  by Landlord or Tenant
shall  be used  until a final  decision  has  been  reached  by the  appropriate
appraiser,  with an  appropriate  rental  credit and other  adjustments  for any
overpayments of Base Rent or other amounts if the appropriate  appraiser selects
Tenant's  estimate  of fair  market.

(l)  Cost of  Appraisers.  The  cost  of each  party's  appraiser  shall  be the
responsibility of the party selecting such appraiser,  and the cost of the third
appraiser  (and,  if  necessary,  arbitration)  shall be shared by Landlord  and
Tenant equally.

(m)   Deleted.

(n)   Deleted.

(o) Effect of  Default.  Tenant  shall have no right to exercise  the  Extension
Option,  notwithstanding  any provision of the grant of the Extension  Option to
the contrary,  and Tenant's exercise of the Extension Option may be nullified by
Landlord  and deemed of no further  force or effect,  if (i) Tenant  shall be in
default of any monetary obligation or material non-monetary obligation under the
terms of this Lease as of Tenant's  exercise of the Extension Option in question
or at any time after the  exercise of such Option and prior to the  commencement
of the Option Term, or (ii) Landlord has given Tenant two (2) or more notices of
default,  whether or not such defaults are subsequently cured, during any twelve
(12) consecutive month period of the Lease.

4.    POSSESSION.

(a)  Delivery  of  Possession.  Landlord  agrees to  deliver  possession  of the
Premises to Tenant in  accordance  with the terms of the Work  Letter  Agreement
attached hereto as Exhibit "C". Notwithstanding the foregoing, Landlord will not
be obligated to deliver possession of the Premises to Tenant (but Tenant will be
liable for rent if Landlord can otherwise  deliver the Premises to Tenant) until
Landlord has received from Tenant all of the following: (i) a copy of this Lease
fully  executed by Tenant and the  guaranty of Tenant's  obligations  under this
Lease,  if any,  executed by the  Guarantor(s);  (ii) the first  installment  of
Monthly  Base  Rent;   (iii)  executed   copies  of  policies  of  insurance  or
certificates  thereof as required under Paragraph 19 of this Lease;  (iv) copies
of all governmental  permits and authorizations,  if any, required in connection
with Tenant's  operation of its business within the Premises;  and (v) if Tenant
is a corporation or partnership, such evidence of due formation, valid existence
and authority as Landlord may  reasonably  require,  which may include,  without
limitation, a certificate of good standing,  certificate of secretary,  articles
of incorporation, statement of partnership, or other similar documentation.

(b) Condition of Premises. Prior to the Commencement Date and in accordance with
the Work Letter  Agreement  attached hereto as Exhibit "C",  Landlord and Tenant
will jointly conduct a walk-through  inspection of the Premises and will jointly
prepare  a  punch-list  ("Punch-List")  of items  required  to be  installed  by
Landlord under the Work Letter Agreement which require  finishing or correction.
The  Punch-List  will not include any items of damage to the Premises  caused by
Tenant's move-in or early entry, if permitted, which damage will be corrected or
repaired by Landlord, at Tenant's expense or, at Landlord's election, by Tenant,
at Tenant's expense. Other than the items specified in the Punch-List, by taking
possession of the Premises,  Tenant will be deemed to have accepted the Premises
in its condition on the date of delivery of possession and to have  acknowledged
that the Tenant  Improvements have been installed as required by the Work Letter
Agreement  and that  there  are no  additional  items  needing  work or  repair.
Landlord  will cause all items in the  Punch-List  to be repaired  or  corrected
within thirty (30) days  following the  preparation of the Punch-List or as soon
as practicable after the preparation of the Punch-List. Tenant acknowledges that
neither  Landlord  nor any  agent of  Landlord  has made any  representation  or
warranty with respect to the  Premises,  the Building,  the  Development  or any
portions  thereof or with respect to the  suitability of same for the conduct of
Tenant's  business and Tenant  further  acknowledges  that Landlord will have no
obligation  to construct or complete any  additional  buildings or  improvements
within the Development.

                                      -5-

(c)  Representations  By Landlord.  Landlord  hereby  represents and warrants as
follows:  (i) the Building,  as of the  Commencement  Date shall comply with all
applicable  covenants or restrictions  of record and applicable  building codes,
regulations  and  ordinances  in  effect  on the  Commencement  Date;  provided,
however,  this warranty shall not apply to any Tenant  Improvements which Tenant
shall cause to be  installed  within the  Premises;  and (ii)  Landlord  has not
caused any  Hazardous  Materials  to be brought  upon,  stored,  used,  handled,
generated,  released  or disposed of on, in,  under or about the  Premises,  the
Building and/or the Common Areas. In the event Tenant does not provide  Landlord
with  a  written  notice  of  a  non-compliance  with  the  representations  and
warranties  set forth in this  subparagraph  4(c)  within  six (6) months of the
Commencement Date,  Landlord's  representations and warranties set forth in this
subparagraph 4(c) shall be deemed to have no further force or effect.

5. RENT.

(a) Monthly Base Rent.  Tenant  agrees to pay Landlord the Monthly Base Rent for
the Premises  (subject to adjustment as hereinafter  provided) in advance on the
first day of each calendar month during the Term without prior notice or demand,
except  that Tenant  agrees to pay the Monthly  Base Rent for the first month of
the Term  directly  to  Landlord  concurrently  with  Tenant's  delivery  of the
executed Lease to Landlord. If the Term of this Lease commences or ends on a day
other than the first day of a calendar month, then the rent for such period will
be  prorated in the  proportion  that the number of days this Lease is in effect
during such period  bears to the number of days in such month.  All rent must be
paid to Landlord, without any deduction or offset, in lawful money of the United
States of America, at the address designated by Landlord or to such other person
or at such other place as Landlord  may from time to time  designate in writing.
Monthly Base Rent will be adjusted  during the Term of this Lease as provided in
subparagraph  l(m).

(b)  Additional  Rent.  All amounts and charges to be paid by Tenant  hereunder,
including,  without  limitation,  payments for  Operating  Expenses,  insurance,
repairs and parking,  will be  considered  additional  rent for purposes of this
Lease,  and the  word  "rent"  as  used in this  Lease  will  include  all  such
additional  rent unless the context  specifically  or clearly  implies that only
Monthly Base Rent is intended.

(c)   Late Payments.  Late payments of Monthly Base Rent and/or any item of
additional rent will be subject to interest and a late charge as provided in
subparagraph 22(f) below.

6.    OPERATING EXPENSES.

(a)  Operating  Expenses.  In addition to Monthly Base Rent,  commencing  on the
first anniversary of the Commencement Date and continuing throughout the Term of
this Lease,  Tenant agrees to pay Landlord as additional rent in accordance with
the terms of this  Paragraph 6,  Tenant's  Percentage  of Operating  Expenses as
defined in Exhibit "E"  attached  hereto to the extent  Tenant's  Percentage  of
Operating Expenses exceeds Tenant's  Operating Expense  Allowance.

(b) Estimate Statement. Prior to the Commencement Date and on or about March 1st
of each  subsequent  calendar year during the Term of this Lease,  Landlord will
endeavor  to  deliver  to  Tenant a  statement  ("Estimate  Statement")  wherein
Landlord will estimate  both the Operating  Expenses and Tenant's  Percentage of
Operating  Expenses  for the then  current  calendar  year.  If the  estimate of
Tenant's  Percentage  of Operating  Expenses in the Estimate  Statement  exceeds
Tenant's  Operating  Expense  Allowance,  Tenant  agrees  to  pay  Landlord,  as
"Additional  Rent",  one-twelfth  (1/12th) of such excess each month thereafter,
beginning  with the next  installment  of rent due,  until such time as Landlord
issues a revised Estimate Statement or the Estimate Statement for the succeeding
calendar year;  except that,  concurrently with the regular monthly rent payment
next due following the receipt of each such Estimate Statement, Tenant agrees to
pay Landlord an amount equal to one monthly installment of such excess (less any
applicable  Operating  Expenses already paid) multiplied by the number of months
from January,  in the current  calendar  year, to the month of such rent payment
next due,  all months  inclusive.  If at any time during the Term of this Lease,
but not more often than quarterly,  Landlord reasonably determines that Tenant's
Percentage of Operating  Expenses for the current  calendar year will be greater
than the amount set forth in the then current Estimate  Statement,  Landlord may
issue a revised Estimate Statement and Tenant agrees to pay Landlord, within ten
(10) days of receipt of the revised Estimate  Statement,  the difference between
the amount owed by Tenant under such revised  Estimate  Statement and the amount
owed by Tenant under the original Estimate Statement for the portion of the then
current  calendar  year  which  has  expired.  Thereafter  Tenant  agrees to pay
Tenant's  Percentage  of  Operating  Expenses  based  on such  revised  Estimate
Statement until Tenant receives the next calendar year's Estimate Statement or a
new revised  Estimate  Statement  for the current  calendar  year.  In the event
Tenant's  Percentage  of Operating  Expenses for any calendar  year is less than
Tenant's  Operating Expense  Allowance,  Tenant will not be entitled to a credit
against any rent,  additional  rent or Tenant's  Percentage of future  Operating
Expenses payable hereunder.

                                      -6-
 27

(c) Actual Statement. By March 1st of each calendar year during the Term of this
Lease  (commencing  March 1 in the  calendar  year  following  the base year for
Operating  Expenses,  if applicable),  Landlord will also endeavor to deliver to
Tenant a  statement  ("Actual  Statement")  which  states the  actual  Operating
Expenses for the preceding  calendar year. If the Actual Statement  reveals that
Tenant's  Percentage  of the actual  Operating  Expenses  is more than the total
Additional  Rent  paid by  Tenant  for  Operating  Expenses  on  account  of the
preceding  calendar year, Tenant agrees to pay Landlord the difference in a lump
sum  within ten (10) days of  receipt  of the  Actual  Statement.  If the Actual
Statement reveals that Tenant's  Percentage of the actual Operating  Expenses is
less than the Additional  Rent paid by Tenant for Operating  Expenses on account
of the preceding calendar year,  Landlord will credit any overpayment toward the
next monthly installment(s) of Tenant's Percentage of the Operating Expenses due
under  this  Lease.

(d)  Miscellaneous.  Any delay or failure by Landlord in delivering any Estimate
Statement or Actual Statement pursuant to this Paragraph 6 will not constitute a
waiver of its right to require an increase in rent nor will it relieve Tenant of
its  obligations  pursuant to this  Paragraph  6, except that Tenant will not be
obligated  to make any  payments  based on such  Estimate  Statement  or  Actual
Statement until ten (10) days after receipt of such Estimate Statement or Actual
Statement. Even though the Term has expired and Tenant has vacated the Premises,
when the  final  determination  is made of  Tenant's  Percentage  of the  actual
Operating Expenses for the year in which this Lease terminates, Tenant agrees to
promptly pay any increase due over the estimated expenses paid and,  conversely,
any  overpayment  made in the event said  expenses  decrease  shall  promptly be
rebated by Landlord to Tenant.  Such  obligation  will be a continuing one which
will survive the expiration or earlier  termination of this Lease.  Prior to the
expiration or sooner termination of the Lease Term and Landlord's  acceptance of
Tenant's surrender of the Premises, Landlord will have the right to estimate the
actual  Operating  Expenses for the then current  Lease Year and to collect from
Tenant prior to Tenant's surrender of the Premises,  Tenant's  Percentage of any
excess of such actual Operating  Expenses over the estimated  Operating Expenses
paid by Tenant in such Lease Year.

(e) Tenant's Audit Rights. Notwithstanding anything to the contrary contained in
this Lease,  if Tenant  reasonably  disputes any amounts set forth in any Actual
Statement  described  above in this  Paragraph  6, Tenant will have the right no
later than sixty (60) days  following  receipt of an Actual  Statement  to cause
Landlord's general ledger of accounts with respect to the immediately  preceding
calendar  year only to be audited by a nationally  recognized  firm of certified
public  accountants  reasonably  approved by Landlord,  at no cost or expense to
Landlord,  by a certified public accountant  mutually acceptable to Landlord and
Tenant and which has prior experience in the review of financial  statements and
which shall not have provided primary  accounting  services to Tenant within the
last three (3) years and which shall not be retained by Tenant on a  contingency
basis;  provided,  however,  Tenant shall not have the right to perform any such
audit  more than one (1) time for any  calendar  year  during  the  Lease  Term,
provided  further,  if any other tenant(s) shall have already initiated an audit
of the Operating  Expenses  during such calendar  year,  Landlord shall have the
right at its option to limit  Tenant's  audit to a review of such other audit(s)
and any reasonable and specific  concerns Tenant may have with any such audit(s)
and Tenant shall not be entitled to reopen Landlord's general ledger of accounts
regarding  Operating Expenses for such calendar year except with respect to such
reasonable and specific concerns of Tenant  concerning such other audit(s).  Any
audit conducted by or on behalf of Tenant shall be performed  within ninety (90)
days and shall be  conducted  at  Landlord's  office  during  Landlord's  normal
business hours and in the manner so as to minimize  interference with Landlord's
business operations.  Landlord shall have no obligation and Tenant shall have no
right to make photocopies of any of Landlord's ledgers, invoices or other items.
Tenant's  audit  shall be  limited to an on-site  review of  Landlord's  general
ledger of accounts.  The amounts  payable under this  Paragraph 6 by Landlord to
Tenant or to  Tenant  to  Landlord,  as the case may be,  will be  appropriately
adjusted on the basis of such audit. If such audit discloses an overstatement of
Operating Expenses in excess of five percent (5%) for such calendar year, Tenant
will receive a credit against Tenant's future Operating Expense  obligations for
the reasonable  costs of such audit;  otherwise the cost of such audit including
Landlord's costs incurred in complying with such audit shall be borne by Tenant.
Tenant  agrees to keep,  and to cause in its account and  employee to keep,  all
information  revealed  by any audit of  Landlord's  books and  records  strictly
confidential  and not to  disclose  any  such  information  or  permit  any such
information to be disclosed to anyone other than Landlord,  unless  compelled to
do so by a court of law.

7.    DELETED.

8.    USE.

(a) Tenant's Use of the  Premises.  The Premises may be used for the use or uses
set forth in  subparagraph  1(r)  only,  and  Tenant  will not use or permit the
Premises to be used for any other purpose  without the prior written  consent of
Landlord,  which  consent  Landlord  may  withhold  in  its  sole  and  absolute
discretion.  Nothing in this Lease will be deemed to give  Tenant any  exclusive
right  to such  use in the  Building  or the  Development.

(b)  Compliance.  At Tenant's  sole cost and expense,  Tenant agrees to procure,
maintain and hold available for Landlord's inspection, all governmental licenses
and permits required for the proper and lawful conduct of Tenant's business from
the Premises,  if any. Tenant agrees not to use, alter or occupy the Premises or
allow the Premises to be used,  altered or occupied in violation of, and Tenant,
at its sole cost and  expense,  agrees to use and occupy the  Premises and cause
the Premises to be used and occupied in compliance  with:  (i) any and all laws,
statutes,  zoning  restrictions,  ordinances,  rules,  regulations,  orders  and
rulings now or hereafter in force and any requirements of any insurer, insurance
authority or duly  constituted  public authority  having  jurisdiction  over the
Premises,  the Building or the Development  now or hereafter in force,  (ii) the
requirements of the Board of Fire Underwriters and any other similar body, (iii)
the  Certificate of Occupancy  issued for the Building.  Tenant shall not use or
permit the Premises to be used for any purpose  which would cause a violation of
any recorded  covenants,  conditions  and  restrictions  and similar  regulatory
agreements,  if any,  which  affect the use,  occupation  or  alteration  of the
Premises, the Building and/or the Development.  Tenant agrees to comply with the
Rules and Regulations  referenced in Paragraph 28 below. Tenant agrees not to do
or permit  anything to be done in or about the Premises which will in any manner
obstruct  or  interfere  with the rights of other  tenants or  occupants  of the
Development,  or injure or unreasonably annoy them, or use or allow the Premises
to be used for any unlawful or unreasonably objectionable purpose. Tenant agrees
not to cause,  maintain or permit any  nuisance or waste in, on,  under or about
the  Premises or  elsewhere  within the  Development.  Notwithstanding  anything
contained in this Lease to the contrary,  all  transferable  development  rights
related in any way to the  Development  are and will remain  vested in Landlord,
and Tenant hereby waives any rights thereto.

(c)  Hazardous  Materials.  Except for  ordinary  and  general  office  supplies
typically used in the ordinary course of business within office buildings,  such
as copier toner, liquid paper, glue, ink and common household cleaning materials
(some or all of which may  constitute  "Hazardous  Materials" as defined in this
Lease),  Tenant  agrees not to cause or permit  any  Hazardous  Materials  to be
brought upon, stored, used, handled, generated,  released or disposed of on, in,
under or about the Premises, the Building, the Common Areas or any other portion
of the  Development by Tenant,  its agents,  employees,  subtenants,  assignees,
licensees,  contractors or invitees (collectively,  "Tenant's Parties"), without
the prior written  consent of Landlord,  which consent  Landlord may withhold in
its sole and absolute discretion.  Upon the expiration or earlier termination of
this Lease, Tenant agrees to promptly remove from the Premises, the Building and
the Development,  at its sole cost and expense, any and all Hazardous Materials,
including  any equipment or systems  containing  Hazardous  Materials  which are
installed,  brought upon, stored, used, generated or released upon, in, under or
about the Premises,  the Building  and/or the Development or any portion thereof
by Tenant or any of Tenant's  Parties.  To the fullest extent  permitted by law,
Tenant agrees to promptly indemnify,  protect, defend and hold harmless Landlord
and Landlord's partners, officers, directors,  employees, agents, successors and
assigns (collectively,  "Landlord Indemnified Parties") from and against any and
all claims, damages,  judgments,  suits, causes of action, losses,  liabilities,
penalties, fines, expenses and costs (including,  without limitation,  clean-up,
removal,  remediation and restoration  costs, sums paid in settlement of claims,
attorneys' fees, consultant fees and expert fees and court costs) which arise or
result  from the  presence of  Hazardous  Materials  on, in,  under or about the
Premises,  the Building or any other  portion of the  Development  and which are
caused or  permitted  by Tenant or any of  Tenant's  Parties.  Tenant  agrees to
promptly notify Landlord of any release of Hazardous  Materials at the Premises,
the Building or any other portion of the Development  which Tenant becomes aware
of during the Term of this Lease,  whether caused by Tenant or any other persons
or  entities.  In the event of any  release  of  Hazardous  Materials  caused or
permitted by Tenant or any of Tenant's  Parties,  Landlord shall have the right,
but not the obligation,  to cause Tenant to immediately  take all steps Landlord
deems necessary or appropriate to remediate such release and prevent any similar
future release to the satisfaction of Landlord and Landlord's  mortgagee(s).  As
used in this Lease,  the term "Hazardous  Materials"  shall mean and include any
hazardous  or  toxic  materials,  substances  or  wastes  as  now  or  hereafter
designated under any law, statute, ordinance, rule, regulation,  order or ruling
of any  agency  of  the  State,  the  United  States  Government  or  any  local
governmental  authority,  including,  without limitation,  asbestos,  petroleum,
petroleum  hydrocarbons  and petroleum based products,  urea  formaldehyde  foam
insulation,   polychlorinated   biphenyls   ("PCBs"),   and   freon   and  other
chlorofluorocarbons.  The provisions of this  subparagraph 8(c) will survive the
expiration or earlier termination of this Lease.

9. NOTICES.  Any notice  required or permitted to be given  hereunder must be in
writing and may be given by personal delivery  (including  delivery by overnight
courier or an express  mailing  service) or by mail,  if sent by  registered  or
certified mail.  Notices to Tenant shall be sufficient if delivered to Tenant at
the address  designated in  subparagraph  1(d) and notices to Landlord  shall be
sufficient if delivered to Landlord at the address  designated  in  subparagraph
1(b).  Either  party may  specify a  different  address  for notice  purposes by
written  notice to the other,  except that the Landlord may in any event use the
Premises as Tenant's address for notice purposes.

10.  BROKERS.  The parties  acknowledge  that the broker(s) who negotiated  this
Lease are stated in subparagraph 1(t). Each party represents and warrants to the
other, that, to its knowledge,  no other broker,  agent or finder (a) negotiated
or was instrumental in negotiating or consummating this Lease on its behalf, and
(b) is or might be entitled to a commission or  compensation  in connection with
this  Lease.  Landlord  and Tenant each agree to  promptly  indemnify,  protect,
defend and hold harmless the other from and against any and all claims, damages,
judgments,  suits,  causes of action,  losses,  liabilities,  penalties,  fines,
expenses and costs  (including  attorneys' fees and court costs)  resulting from
any breach by the indemnifying party of the foregoing representation, including,
without  limitation,  any claims that may be  asserted  by any broker,  agent or
finder  undisclosed by the  indemnifying  party.  The foregoing mutual indemnity
shall  survive  the  expiration  or  earlier  termination  of  this  Lease.

11. SURRENDER; HOLDING OVER.

(a) Surrender.  The voluntary or other  surrender of this Lease by Tenant,  or a
mutual  cancellation  thereof,  shall not constitute a merger, and shall, at the
option of Landlord, operate as an assignment to Landlord of any or all subleases
or  subtenancies.  Upon the  expiration  or earlier  termination  of this Lease,
Tenant agrees to peaceably surrender the Premises to Landlord broom clean and in
a state of first-class order,  repair and condition,  ordinary wear and tear and
casualty  damage (if this Lease is  terminated as a result  thereof  pursuant to
Paragraph 20) excepted,  with all of Tenant's  personal property and Alterations
(as defined in Paragraph  13) removed  from the Premises to the extent  required
under Paragraph 13 and all damage caused by such removal repaired as required by
Paragraph 13. Prior to the date Tenant is to actually  surrender the Premises to
Landlord,  Tenant agrees to give Landlord  reasonable  prior notice of the exact
date Tenant will surrender the Premises so that Landlord and Tenant can schedule
a  walk-through  of the  Premises to review the  condition  of the  Premises and
identify  the  Alterations  and personal  property  which are to remain upon the
Premises and which items Tenant is to remove,  as well as any repairs  Tenant is
to make upon surrender of the Premises.  The delivery of keys to any employee of
Landlord  or to  Landlord's  agent or any  employee  thereof  alone  will not be
sufficient  to  constitute  a  termination  of this Lease or a surrender  of the
Premises.

                                      -9-
 30

(b) Holding  Over.  Tenant will not be permitted to hold over  possession of the
Premises  after the  expiration or earlier  termination  of the Term without the
express written consent of Landlord,  which consent Landlord may withhold in its
sole and  absolute  discretion.  If Tenant  holds over after the  expiration  or
earlier termination of the Term, Landlord may, at its option,  treat Tenant as a
tenant at  sufferance  only,  and such  continued  occupancy  by Tenant shall be
subject to all of the terms,  covenants and conditions of this Lease,  so far as
applicable, except that the Monthly Base Rent for any such holdover period shall
be equal to the greater of (i) one  hundred  twenty-five  percent  (125%) of the
Monthly Base Rent in effect under this Lease immediately prior to such holdover,
or (ii) the then currently  scheduled  rental rate for  comparable  space in the
Building,  in either event prorated on a daily basis.  Acceptance by Landlord of
rent after such expiration or earlier  termination  will not result in a renewal
of this Lease. The foregoing  provisions of this Paragraph 11 are in addition to
and do not affect  Landlord's  right of re-entry or any rights of Landlord under
this Lease or as otherwise  provided by law. If Tenant  fails to  surrender  the
Premises upon the expiration of this Lease in accordance  with the terms of this
Paragraph  11 despite  demand to do so by  Landlord,  Tenant  agrees to promptly
indemnify,  protect, defend and hold Landlord harmless from all claims, damages,
judgments,  suits,  causes of action,  losses,  liabilities,  penalties,  fines,
expenses and costs  (including  attorneys' fees and costs),  including,  without
limitation, costs and expenses incurred by Landlord in returning the Premises to
the  condition  in which  Tenant  was to  surrender  it and  claims  made by any
succeeding tenant founded on or resulting from Tenant's failure to surrender the
Premises.  The provisions of this subparagraph 11(b) will survive the expiration
or earlier termination of this Lease.

12. TAXES ON TENANT'S  PROPERTY.  Tenant agrees to pay before  delinquency,  all
taxes and  assessments  (real and  personal)  levied  against  (a) any  personal
property or trade fixtures placed by Tenant in or about the Premises  (including
any increase in the assessed  value of the Premises  based upon the value of any
such personal  property or trade fixtures);  and (b) any Tenant  Improvements or
Alterations in the Premises  (whether  installed  and/or paid for by Landlord or
Tenant) to the extent such items are  assessed  at a  valuation  higher than the
valuation  at  which  tenant  improvements  conforming  to  Landlord's  building
standard tenant improvements are assessed.  If any such taxes or assessments are
levied  against  Landlord or Landlord's  property,  Landlord may,  after written
notice to Tenant  (and under  proper  protest if  requested  by Tenant) pay such
taxes and  assessments,  in which event Tenant agrees to reimburse  Landlord all
amounts paid by Landlord within ten (10) business days after demand by Landlord;
provided,  however,  Tenant, at its sole cost and expense,  will have the right,
with  Landlord's   cooperation,   to  bring  suit  in  any  court  of  competent
jurisdiction  to recover  the amount of any such taxes and  assessments  so paid
under protest.

13.  ALTERATIONS.  After installation of the initial Tenant Improvements for the
Premises pursuant to Exhibit "C", Tenant may, at its sole cost and expense, make
alterations,   additions,   improvements   and   decorations   to  the  Premises
(collectively,  "Alterations")  subject  to and upon  the  following  terms  and
conditions:

(a)  Prohibited  Alterations.  Tenant may not make any  Alterations  which:  (i)
affect any area  outside the  Premises;  (ii) affect the  Building's  structure,
equipment, services or systems, or the proper functioning thereof, or Landlord's
access  thereto;  (iii) affect the outside  appearance,  character or use of the
Building  or the  Building  Common  Areas;  (iv) in the  reasonable  opinion  of
Landlord,  lessen the value of the  Building;  or (v) will  violate or require a
change in any occupancy certificate  applicable to the Premises.

(b) Landlord's  Approval.  Before  proceeding with any Alterations which are not
prohibited  in  subparagraph  13(a) above,  Tenant must first obtain  Landlord's
written  approval of the plans,  specifications  and working  drawings  for such
Alterations,  which approval  Landlord will not unreasonably  withhold or delay;
provided,  however,  Landlord's prior approval will not be required for any such
Alterations which are not prohibited by subparagraph  13(a) above and which cost
less than Fifty Thousand  Dollars  ($50,000.00) in the aggregate in any calendar
year as long as (i) Tenant  delivers to Landlord  notice and a copy of any final
plans, specifications and working drawings for any such Alterations at least ten
(10)  days  prior to  commencement  of the  work  thereof,  and  (ii) the  other
conditions  of  this   Paragraph  13  are   satisfied,   excluding  any  bonding
requirements, but including, without limitation, conforming to Landlord's rules,
regulations  and insurance  requirements  which govern  contractors.  Landlord's
approval of plans,  specifications  and/or working drawings for Alterations will
not create any  responsibility  or  liability  on the part of Landlord for their
completeness,  design sufficiency,  or compliance with applicable permits, laws,
rules and regulations of governmental agencies or authorities.  In approving any
Alterations,  Landlord  reserves the right to require Tenant to provide Landlord
with  additional  reasonable  security  for the removal of such  Alterations  by
Tenant as may be  required by this Lease.  Landlord  reserves  the right to post
Notices of  Non-Responsibility  with  respect to any  Alterations  performed  by
Tenant.

                                      -10-
 31

(c)  Contractors.  Alterations  may be made or installed only by contractors and
subcontractors  which have been approved by Landlord,  which  approval  Landlord
will not unreasonably withhold or delay;  provided,  however,  Landlord reserves
the right to require that  Landlord's  contractor  for the Building be given the
opportunity  to  bid  for  any  Alteration  work.  Before  proceeding  with  any
Alterations,  Tenant agrees to provide Landlord with ten (10) days prior written
notice and Tenant's  contractors  must obtain and maintain,  on behalf of Tenant
and at Tenant's sole cost and expense:  (i) all necessary  governmental  permits
and approvals for the commencement and completion of such Alterations;  and (ii)
if requested by Landlord, a completion and lien indemnity bond, or other surety,
reasonably  satisfactory  to  Landlord  for  such  Alterations.  Throughout  the
performance  of  any  Alterations,   Tenant  agrees  to  obtain,  or  cause  its
contractors  to obtain,  workers  compensation  insurance and general  liability
insurance in compliance with the provisions of Paragraph 19 of this Lease.

(d) Manner of Performance.  All Alterations must be performed: (i) in accordance
with  the  approved  plans,  specifications  and  working  drawings;  (ii)  in a
lien-free and first-class and workmanlike  manner;  (iii) in compliance with all
applicable permits, laws, statutes,  ordinances, rules, regulations,  orders and
rulings now or hereafter in effect and imposed by any governmental  agencies and
authorities  which  assert  jurisdiction;  (iv)  in such a  manner  so as not to
interfere with the occupancy of any other tenant in the Building, nor impose any
additional  expense upon nor delay Landlord in the  maintenance and operation of
the Building;  and (v) at such times, in such manner,  and subject to such rules
and regulations as Landlord may from time to time reasonably designate.

(e) Ownership.  The Tenant  Improvements,  including,  without  limitation,  all
affixed  sinks,  dishwashers,  microwave  ovens  and  other  fixtures,  and  all
Alterations  will become the  property  of Landlord  and will remain upon and be
surrendered  with the  Premises at the end of the Term of this Lease;  provided,
however,  Landlord may, by written notice delivered to Tenant  concurrently with
Landlord's approval of the final working drawings for any Alterations,  identify
those Alterations which Landlord will require Tenant to remove at the end of the
Term of this Lease. Landlord may also require Tenant to remove Alterations which
Landlord did not have the  opportunity  to approve as provided in this Paragraph
13. If Landlord  requires Tenant to remove any Alterations,  Tenant, at its sole
cost and expense,  agrees to remove the identified  Alterations on or before the
expiration  or  earlier  termination  of this Lease and repair any damage to the
Premises caused by such removal (or, at Landlord's option,  Tenant agrees to pay
to Landlord all of Landlord's costs of such removal and repair).

(f) Plan  Review.  Tenant  agrees  to pay  Landlord,  as  additional  rent,  the
reasonable  costs of professional  services and costs for general  conditions of
Landlord's  third party  consultants if utilized by Landlord (but not Landlord's
"in-house"  personnel)  for  review of all  plans,  specifications  and  working
drawings  for any  Alterations,  within ten (10)  business  days after  Tenant's
receipt of invoices  either  from  Landlord or such  consultants.  In  addition,
Tenant agrees to pay Landlord, within ten (10) business days after completion of
any   Alterations,   a  fee  to  cover   Landlord's  costs  of  supervising  and
administering the installation of any non-structural  Alterations, in the amount
of three percent (3%) of the cost of such Alterations, but in no event less than
Two Hundred  Fifty Dollars  ($250.00).

(g)  Personal  Property.  All articles of personal  property  owned by Tenant or
installed by Tenant at its expense in the Premises  (including Tenant's business
and  trade  fixtures,  furniture,  movable  partitions  and  equipment  [such as
telephones,  copy  machines,  computer  terminals,  refrigerators  and facsimile
machines])  will be and remain the  property  of Tenant,  and must be removed by
Tenant from the Premises,  at Tenant's  sole cost and expense,  on or before the
expiration  or earlier  termination  of this Lease.  Tenant agrees to repair any
damage caused by such removal at its cost on or before the expiration or earlier
termination of this Lease.

                                      -11-
 32

(h)  Removal of  Alterations.  If Tenant  fails to remove by the  expiration  or
earlier  termination  of  this  Lease  all  of  its  personal  property,  or any
Alterations  identified  by Landlord for removal,  Landlord  may, at its option,
treat such failure as a hold-over pursuant to subparagraph  11(b) above,  and/or
Landlord may (without  liability to Tenant for loss thereof) treat such personal
property and/or Alterations as abandoned and, at Tenant's sole cost and expense,
and in addition to Landlord's other rights and remedies under this Lease, at law
or in  equity:  (a remove and store  such  items;  and/or (b) upon ten (10) days
prior notice to Tenant,  sell,  discard or otherwise  dispose of all or any such
items at private  or public  sale for such  price as  Landlord  may obtain or by
other  commercially  reasonable  means.  Tenant shall be liable for all costs of
disposition of Tenant's  abandoned property and Landlord shall have no liability
to Tenant with respect to any such abandoned property.  Landlord agrees to apply
the  proceeds  of any sale of any such  property  to any amounts due to Landlord
under this Lease from Tenant  (including  Landlord's  attorneys'  fees and other
costs  incurred in the removal,  storage  and/or sale of such  items),  with any
remainder to be paid to Tenant.

14.   REPAIRS.

(a)  Landlord's  Obligations.   Landlord  agrees  to  repair  and  maintain  the
structural portions of the Building and the plumbing, heating,  ventilating, air
conditioning,   elevator  and  electrical  systems  installed  or  furnished  by
Landlord,  unless such  maintenance  and repairs are (i)  attributable  to items
installed in Tenant's  Premises which are above standard  interior  improvements
(such as, for example, custom lighting, special HVAC and/or electrical panels or
systems,  kitchen or restroom facilities and appliances constructed or installed
within Tenant's Premises) or (ii) caused in part or in whole by the act, neglect
or omission of any duty by Tenant, its agents, servants,  employees or invitees,
in which case Tenant will pay to Landlord,  as additional  rent,  the reasonable
cost of such  maintenance  and  repairs.  Landlord  will not be  liable  for any
failure to make any such  repairs  or to perform  any  maintenance  unless  such
failure shall persist for an unreasonable  time after written notice of the need
of such  repairs  or  maintenance  is given to  Landlord  by  Tenant.  Except as
provided in Paragraph  20,  Tenant will not be entitled to any abatement of rent
and  Landlord  will  not  have any  liability  by  reason  of any  injury  to or
interference  with  Tenant's  business  arising  from the making of any repairs,
alterations or improvements in or to any portion of the Building or the Premises
or in or to fixtures,  appurtenances  and equipment  therein.  Tenant waives the
right to make repairs at Landlord's  expense under any law, statute,  ordinance,
rule, regulation, order or ruling (including,  without limitation, to the extent
the Premises are located in California,  the provisions of California Civil Code
Sections 1941 and 1942 and any successor  statutes or laws of a similar nature).

(b)  Tenant's  Obligations.  Tenant  agrees to keep,  maintain  and preserve the
Premises  in first  class  condition  and repair  and,  when and if  needed,  at
Tenant's  sole cost and  expense,  to make all repairs to the Premises and every
part thereof.  Any such  maintenance and repairs will be performed by Landlord's
contractor, or at Landlord's option, by such contractor or contractors as Tenant
may choose from an approved  list to be submitted by Landlord.  Tenant agrees to
pay all costs and expenses  incurred in such maintenance and repair within seven
(7) days after  billing by Landlord or such  contractor or  contractors.  Tenant
agrees to cause any mechanics'  liens or other liens arising as a result of work
performed  by Tenant or at Tenant's  direction to be  eliminated  as provided in
Paragraph 15 below. Except as provided in subparagraph 14(a) above, Landlord has
no obligation to alter, remodel, improve, repair, decorate or paint the Premises
or any part  thereof.

(c)  Tenant's  Failure to Repair.  If Tenant  refuses or  neglects to repair and
maintain  the  Premises  properly  as  required   hereunder  to  the  reasonable
satisfaction of Landlord,  Landlord, at any time following thirty (30) days from
the date on which  Landlord  makes a written  demand  on  Tenant to effect  such
repair and maintenance, may enter upon the Premises and make such repairs and/or
maintenance,  and upon completion  thereof,  Tenant agrees to pay to Landlord as
additional rent,  Landlord's costs for making such repairs plus an amount not to
exceed ten percent (10%) of such costs for overhead,  within thirty (30) days of
receipt  from  Landlord of a written  itemized  bill  therefor.  Any amounts not
reimbursed  by Tenant  within such thirty (30) day period will bear  interest at
the Interest Rate until paid by Tenant.

                                      -12-

(d) Landlord Repairs/Default. Notwithstanding anything to the contrary contained
in Paragraph 14(a) regarding repairs or Landlord's  default,  if Tenant provides
written notice to Landlord of an event or circumstance  relative to the Premises
which requires the action of Landlord with respect to repair and/or maintenance,
and Landlord  fails to provide such action  within a reasonable  period of time,
given the  circumstances,  after the receipt of such written  notice,  but in no
event earlier than thirty (30) days after receipt of such written notice, unless
Landlord is specifically  required to act in less than thirty (30) days pursuant
to a  specific  provision  of this  Lease  or  because  of an  emergency  by any
provision  hereof,  then  Tenant may  proceed to take the  required  action upon
delivery of an additional written notice to Landlord specifying Tenant is taking
such required action, including the date of such action to be taken, the cost of
such action, and the projected  completion date, and if such action was required
under the terms of this  Lease to be taken by  Landlord,  then  Tenant  shall be
entitled to prompt  reimbursement  by Landlord of Tenant's  reasonable,  actual,
documented costs and expenses in taking such action plus interest thereon at the
Interest  Rate.  In the event  Tenant  takes such  action,  and such work in the
Premises will affect the Building's life safety system, heating, ventilating and
air conditioning  systems and elevator systems,  or the structural  integrity of
the Building,  Tenant shall use only those  contractors  used by Landlord in the
Building  for work on such  systems or other  contractors  approved by Landlord.
Further,  if Landlord  does not deliver a detailed  written  objection to Tenant
within  thirty  (30) days after  receipt of an invoice by Tenant of its costs of
taking  action which Tenant  claims  should have been taken by Landlord,  and if
such invoice from Tenant sets forth a reasonably particularized breakdown of its
costs and expenses in connection  with taking such action on behalf of Landlord,
then Tenant shall be entitled to deduct from rental payable by Tenant under this
Lease, the amount set forth in such invoice.  If, however,  Landlord delivers to
Tenant  within  thirty (30) days after  receipt of Tenant's  invoice,  a written
objection  to the  payment  of  such  invoice,  setting  forth  with  reasonable
particularity  Landlord's reasons for its claim that such action did not have to
be taken by Landlord  pursuant to the terms of this Lease, then Tenant shall not
be entitled to such deduction from rental,  but as Tenant's sole remedy,  Tenant
may proceed to claim a default by Landlord or, if elected by either  Landlord or
Tenant, the matter shall proceed to resolution by the selection of an arbitrator
to resolve  the  dispute,  which  arbitrator  shall be  selected  and  qualified
pursuant to the rules of the American Arbitration  Association,  and whose costs
shall be paid for by the  losing  party,  unless it is not clear that there is a
"losing party," in which event the costs of arbitration shall be shared equally.
Judgment on the award rendered by the  arbitrator(s) may be entered in any court
having jurisdiction thereof.

15. LIENS.  Tenant agrees not to permit any mechanic's,  materialmen's  or other
liens to be filed  against all or any part of the  Development,  the Building or
the Premises, nor against Tenant's leasehold interest in the Premises, by reason
of or in connection  with any repairs,  alterations,  improvements or other work
contracted for or undertaken by Tenant or any other act or omission of Tenant or
Tenant's agents,  employees,  contractors,  licensees or invitees. At Landlord's
request,  Tenant agrees to provide  Landlord with  enforceable,  conditional and
final lien  releases  (or other  evidence  reasonably  requested  by Landlord to
demonstrate  protection  from liens) from all persons  furnishing  labor  and/or
materials at the Premises.  Landlord will have the right at all reasonable times
to post on the  Premises and record any notices of  non-responsibility  which it
deems  necessary for  protection  from such liens.  If any such liens are filed,
Tenant  will,  at its sole cost,  promptly  cause such liens to be  released  of
record  or bonded so that it no longer  affects  title to the  Development,  the
Building  or the  Premises.  If Tenant  fails to cause  any such  liens to be so
released or bonded within ten (10) days after filing thereof,  such failure will
be deemed a material  breach by Tenant  under this Lease  without the benefit of
any  additional  notice or cure period  described  in  Paragraph  22 below,  and
Landlord may, without waiving its rights and remedies based on such breach,  and
without  releasing  Tenant from any of its  obligations,  cause such liens to be
released by any means it shall deem proper, including payment in satisfaction of
the claims giving rise to such liens.  Tenant  agrees to pay to Landlord  within
ten (10) days after receipt of invoice from  Landlord,  any sum paid by Landlord
to remove such liens,  together with interest at the Interest Rate from the date
of such payment by Landlord.

16. ENTRY BY LANDLORD.  Landlord and its  employees and agents will at all times
have the right to enter the Premises to inspect the same,  to supply  janitorial
service and any other service to be provided by Landlord to Tenant hereunder, to
show the  Premises to  prospective  purchasers  or tenants,  to post  notices of
nonresponsibility,  and/or to repair the  Premises as  permitted  or required by
this Lease. In exercising such entry rights, Landlord will endeavor to minimize,
as reasonably  practicable,  the interference with Tenant's  business,  and will
provide  Tenant  with  reasonable  advance  notice of any such entry  (except in
emergency situations).  Landlord may, in order to carry out such purposes, erect
scaffolding  and other necessary  structures  where  reasonably  required by the
character  of the work to be  performed.  Landlord  will at all  times  have and
retain a key with which to unlock all doors in the Premises,  excluding Tenant's
vaults and safes.  Landlord  will have the right to use any and all means  which
Landlord may reasonably  deem proper to open said doors in an emergency in order
to obtain entry to the Premises.  Any entry to the Premises obtained by Landlord
by any of said means,  or  otherwise,  will not be  construed  or deemed to be a
forcible or unlawful entry into the Premises,  or an eviction of Tenant from the
Premises.  Landlord  will not be liable to Tenant for any  damages or losses for
any entry by Landlord.

                                      -13-
 34

17.  UTILITIES  AND  SERVICES.  Throughout  the Term of the Lease so long as the
Premises are  occupied,  Landlord  agrees to furnish or cause to be furnished to
the Premises the utilities and services described in the Standards for Utilities
and Services  attached  hereto as Exhibit "F",  subject to the conditions and in
accordance  with the standards set forth  therein.  Landlord may require  Tenant
from time to time to provide  Landlord with a list of Tenant's  employees and/or
agents which are  authorized  by Tenant to subscribe on behalf of Tenant for any
additional  services  which may be provided  by  Landlord.  Any such  additional
services  will be  provided  to Tenant at Tenant's  cost.  Landlord  will not be
liable to Tenant for any failure to furnish any of the  foregoing  utilities and
services if such failure is caused by all or any of the following: (i) accident,
breakage or repairs; (ii) strikes,  lockouts or other labor disturbance or labor
dispute of any character;  (iii)  governmental  regulation,  moratorium or other
governmental  action  or  inaction;  (iv)  inability  despite  the  exercise  of
reasonable  diligence  to obtain  electricity,  water or fuel;  or (v) any other
cause beyond Landlord's  reasonable  control.  In addition,  in the event of any
stoppage or interruption of services or utilities,  Tenant shall not be entitled
to any  abatement  or  reduction  of  rent  (except  as  expressly  provided  in
subparagraphs  20(f) or 21(b) if such  failure  results  from a damage or taking
described  therein),  no eviction  of Tenant  will result from such  failure and
Tenant will not be relieved from the performance of any covenant or agreement in
this Lease  because of such  failure.  In the event of any failure,  stoppage or
interruption  thereof,  Landlord agrees to diligently  attempt to resume service
promptly.  If Tenant requires or utilizes more water or electrical power than is
considered reasonable or normal by Landlord,  Landlord may at its option require
Tenant to pay, as additional  rent, the cost, as fairly  determined by Landlord,
incurred by such  extraordinary  usage  and/or  Landlord  may  install  separate
meter(s)  for  the  Premises,  at  Tenant's  sole  expense,  and  Tenant  agrees
thereafter to pay all charges of the utility providing service and Landlord will
make an appropriate  adjustment to Tenant's  Operating  Expenses  calculation to
account for the fact Tenant is directly  paying such metered  charges,  provided
Tenant  will  remain  obligated  to pay its  proportionate  share  of  Operating
Expenses  subject to such  adjustment.  Notwithstanding  the  provisions of this
Paragraph 17, if for more than three (3)  consecutive  business  days  following
written notice to Landlord,  there is no elevator service to the Premises, or no
HVAC or electricity to the Premises,  or such an interruption of other essential
utilities and building  services,  such as fire protection or water, so that any
portion  of the  Premises  cannot  be  used  by  Tenant,  in  Tenant's  judgment
reasonably  exercised,  then Tenant's rent shall  thereafter be abated until the
Premises  are  again  usable  by Tenant  in  proportion  to the  extent to which
Tenant's use of the Premises is  interfered  with;  provided,  however,  that if
Landlord is  diligently  pursuing  the repair of such  utilities or services and
Landlord provides substitute services reasonably suitable for Tenant's purposes,
as for  example,  bringing in portable  air-conditioning  equipment,  then there
shall not be any abatement of rent.  This  provision  shall not apply in case of
damage to, or  destruction  of,  the  Premises,  which  shall be  governed  by a
separate provision of this Lease.

18.   ASSUMPTION OF RISK AND INDEMNIFICATION.

(a)  Assumption  of Risk.  Tenant,  as a material part of the  consideration  to
Landlord,  hereby  agrees that neither  Landlord  nor any  Landlord  Indemnified
Parties  (as defined in  subparagraph  8(c) above) will be liable to Tenant for,
and Tenant  expressly  assumes  the risk of and waives any and all claims it may
have against Landlord or any Landlord  Indemnified  Parties with respect to, (i)
any and all  damage  to  property  or injury to  persons  in,  upon or about the
Premises,  the Building or the  Development  resulting  from any act or omission
(except for the grossly negligent or intentionally  wrongful act or omission) of
Landlord,  (ii) any such damage  caused by other  tenants or persons in or about
the  Building or the  Development,  or caused by  quasi-public  work,  (iii) any
damage to property  entrusted to employees of the Building,  (iv) any loss of or
damage to property by theft or otherwise, or (v) any injury or damage to persons
or property  resulting from any casualty,  explosion,  falling  plaster or other
masonry or glass, steam, gas, electricity, water or rain which may leak from any
part of the Building or any other portion of the  Development or from the pipes,
appliances or plumbing  works therein or from the roof,  street or subsurface or
from any other place,  or resulting from dampness.  Notwithstanding  anything to
the  contrary  contained  in this  Lease,  neither  Landlord  nor  any  Landlord
Indemnified Parties will be liable for consequential  damages arising out of any
loss of the use of the Premises or any equipment or facilities therein by Tenant
or any  Tenant  Parties  or for  interference  with  light or other  incorporeal
hereditaments.  Tenant  agrees to give prompt notice to Landlord in case of fire
or accidents in the Premises or the  Building,  or of defects  therein or in the
fixtures  or  equipment.

                                      -14-
 35

(b)  Indemnification.  Except to the extent that the Indemnified  Claim would be
covered by  insurance  coverage  maintained  by Landlord  and would not cause an
increase to applicable  premiums charged for Landlord's  insurance  policy(ies),
Tenant will be liable for, and agrees,  to the maximum extent  permissible under
applicable  law,  to  promptly  indemnify,  protect,  defend  and hold  harmless
Landlord and all Landlord  Indemnified  Parties,  from and against,  any and all
claims,  damages,  judgments,  suits,  causes of  action,  losses,  liabilities,
penalties,  fines, expenses and costs, including attorneys' fees and court costs
(collectively,  "Indemnified Claims"),  arising or resulting from (i) any act or
omission  of Tenant or any  Tenant  Parties  (as  defined in  subparagraph  8(c)
above);  (ii) the use of the  Premises  and Common Areas and conduct of Tenant's
business by Tenant or any Tenant Parties,  or any other activity,  work or thing
done,  permitted  or suffered by Tenant or any Tenant  Parties,  in or about the
Premises,  the Building or elsewhere  within the  Development;  and/or (iii) any
default by Tenant of any  obligations on Tenant's part to be performed under the
terms of this  Lease.  In case any  action  or  proceeding  is  brought  against
Landlord or any Landlord  Indemnified  Parties by reason of any such Indemnified
Claims, Tenant, upon notice from Landlord, agrees to promptly defend the same at
Tenant's sole cost and expense by counsel approved in writing by Landlord, which
approval Landlord will not unreasonably withhold.

(c)   Survival; No Release of Insurers.  Tenant's indemnification obligations
under subparagraph 18(b) will survive the expiration or earlier termination
of this Lease.  Tenant's covenants, agreements and indemnification obligation
in subparagraphs 18(a) and 18(b) above, are not intended to and will not
relieve any insurance carrier of its obligations under policies required to
be carried by Tenant pursuant to the provisions of this Lease.

19.   INSURANCE.

(a)  Tenant's  Insurance.  On  or  before  the  earlier  to  occur  of  (i)  the
Commencement Date, or (ii) the date Tenant commences any work of any type in the
Premises  pursuant to this Lease (which may be prior to the Commencement  Date),
and  continuing  throughout  the  entire  Term  hereof  and any other  period of
occupancy,  Tenant agrees to keep in full force and effect, at its sole cost and
expense, the following insurance:

(i) "All Risks" property insurance including at least the following perils: fire
and extended coverage, smoke damage,  vandalism,  malicious mischief,  sprinkler
leakage (including earthquake sprinkler leakage).  This insurance policy must be
upon all property owned by Tenant,  for which Tenant is legally liable, or which
is  installed  at  Tenant's  expense,  and  which  is  located  in the  Building
including,  without  limitation,  any  Tenant  Improvements  which  satisfy  the
foregoing  qualification  and  any  Alterations,  and all  furniture,  fittings,
installations,  fixtures and any other personal property of Tenant, in an amount
not less than the full  replacement  cost  thereof.  If there is a dispute as to
full  replacement  cost,  the decision of Landlord or any  mortgagee of Landlord
will be presumptive.

(ii) One (1) year  insurance  coverage  for  business  interruption  and loss of
income and extra  expense  insuring the same perils  described  in  subparagraph
19(a)(i)  above,  in such  amounts  as will  reimburse  Tenant for any direct or
indirect loss of earnings  attributable to any such perils including  prevention
of access to the Premises, Tenant's parking areas or the Building as a result of
any such perils.

(iii) Commercial General Liability Insurance or Comprehensive  General Liability
Insurance (on an occurrence  form) insuring  bodily injury,  personal injury and
property  damage  including the following  divisions and extensions of coverage:
Premises and Operations; Owners and Contractors protective;  blanket contractual
liability  (including  coverage for Tenant's  indemnity  obligations  under this
Lease);  products and completed  operations;  liquor liability (if Tenant serves
alcohol on the Premises); and fire and water damage legal liability in an amount
sufficient  to cover the  replacement  value of the Premises,  including  Tenant
Improvements, that are rented under the terms of this Lease. Such insurance must
have the following minimum limits of liability:  bodily injury,  personal injury
and property  damage - $1,000,000  each  occurrence,  provided that if liability
coverage  is  provided  by a  Commercial  General  Liability  policy the general
aggregate  limit shall apply  separately and in total to this location only (per
location  general  aggregate),  and provided  further,  such  minimum  limits of
liability may be adjusted from year to year to reflect increases in coverages as
recommended by Landlord's  insurance  carrier as being prudent and  commercially
reasonable  for  tenants  of first  class  office  buildings  comparable  to the
Building, rounded to the nearest five hundred thousand dollars.

                                      -15-
 36

(iv)  Comprehensive  Automobile  Liability  insuring  bodily injury and property
damage  arising  from all owned,  non-owned  and hired  vehicles,  if any,  with
minimum   limits  of  liability  of  $1,000,000   per  accident.

(v)  Worker's  Compensation  as required by the laws of the State of  California
with the following minimum limits of liability: Coverage A - statutory benefits;
Coverage B - $1,000,000 per accident and disease.

(vi)  Any  other  form or  forms of  insurance  as  Tenant  or  Landlord  or any
mortgagees  of Landlord may  reasonably  require  from time to time in form,  in
amounts,  and for insurance  risks against which, a prudent tenant would protect
itself, but only to the extent coverage for such risks and amounts are available
in the insurance  market at  commercially  acceptable  rates.  Landlord makes no
representation  that the limits of  liability  required  to be carried by Tenant
under the terms of this Lease are  adequate to protect  Tenant's  interests  and
Tenant should obtain such additional  insurance or increased liability limits as
Tenant deems appropriate.

(b) Supplemental Tenant Insurance Requirements.

(i) All  policies  must be in a form  reasonably  satisfactory  to Landlord  and
issued by an insurer  admitted to do business in the State of  California.

(ii) All policies must be issued by insurers with a  policyholder  rating of "A"
and a financial  rating of "X" in the most  recent  version of Best's Key Rating
Guide.

(iii) All policies must contain a requirement to notify Landlord (and Landlord's
property  manager and any mortgagees or ground lessors of Landlord who are named
as additional insureds,  if any) in writing not less than thirty (30) days prior
to any material change, reduction in coverage, cancellation or other termination
thereof.  Tenant  agrees to deliver to Landlord,  as soon as  practicable  after
placing the required insurance, but in any event within the time frame specified
in subparagraph  19(a) above,  certificate(s) of insurance and/or if required by
Landlord,  certified  copies of each policy  evidencing  the  existence  of such
insurance and Tenant's  compliance  with the  provisions  of this  Paragraph 19.
Tenant agrees to cause  replacement  policies or certificates to be delivered to
Landlord  not less than  thirty  (30) days prior to the  expiration  of any such
policy or policies.  If any such initial or replacement policies or certificates
are not furnished within the time(s) specified herein,  Tenant will be deemed to
be in material  default under this Lease  without the benefit of any  additional
notice or cure period provided in  subparagraph  22(a)(ii)  below,  and Landlord
will have the right,  but not the  obligation,  to  procure  such  insurance  as
Landlord deems necessary to protect Landlord's interests at Tenant's expense. If
Landlord obtains any insurance that is the  responsibility  of Tenant under this
Paragraph 19, Landlord agrees to deliver to Tenant a written  statement  setting
forth the cost of any such insurance and showing in reasonable detail the manner
in which it has been computed and Tenant agrees to promptly  reimburse  Landlord
for such costs as additional rent.

(iv) General  Liability and Automobile  Liability  policies under  subparagraphs
19(a)(iii) and 19(a)(iv) must name Landlord and Landlord's property manager (and
at Landlord's request,  Landlord's mortgagees and ground lessors of which Tenant
has been  informed in writing) as  additional  insureds  and must also contain a
provision  that the insurance  afforded by such policy is primary  insurance and
any insurance carried by Landlord and Landlord's  property manager or Landlord's
mortgagees or ground lessors,  if any, will be excess over and  non-contributing
with Tenant's  insurance.

(c) Tenant's Use.  Tenant will not keep,  use, sell or offer for sale in or upon
the  Premises  any  article  which may be  prohibited  by any  insurance  policy
periodically in force covering the Building or the Development  Common Areas. If
Tenant's occupancy or business in, or on, the Premises,  whether or not Landlord
has consented to the same, results in any increase in premiums for the insurance
periodically carried by Landlord with respect to the Building or the Development
Common  Areas or  results  in the need  for  Landlord  to  maintain  special  or
additional  insurance,  Tenant  agrees  to pay  Landlord  the  cost of any  such
increase in premiums or special or additional coverage as additional rent within
ten (10) days after being billed  therefor by Landlord.  In determining  whether
increased  premiums  are a result of Tenant's  use of the  Premises,  a schedule
issued by the  organization  computing the insurance  rate on the Building,  the
Development  Common  Areas  or  the  Tenant  Improvements  showing  the  various
components of such rate,  will be  conclusive  evidence of the several items and
charges  which make up such rate.  Tenant  agrees to  promptly  comply  with all
reasonable  requirements  of the  insurance  authority  or any present or future
insurer relating to the Premises.

                                      -16-
 37

(d) Cancellation of Landlord's Policies. If any of Landlord's insurance policies
are  cancelled  or  cancellation  is  threatened  or  the  coverage  reduced  or
threatened  to be reduced in any way  because of the use of the  Premises or any
part  thereof  by Tenant or any  assignee  or  subtenant  of Tenant or by anyone
Tenant  permits on the  Premises  and, if Tenant  fails to remedy the  condition
giving  rise  to  such  cancellation,   threatened  cancellation,  reduction  of
coverage,  threatened reduction of coverage, increase in premiums, or threatened
increase in premiums, within forty-eight (48) hours after notice thereof, Tenant
will be deemed to be in material  default of this Lease and Landlord may, at its
option,  either  terminate  this Lease or enter upon the Premises and attempt to
remedy such  condition,  and Tenant shall  promptly pay Landlord the  reasonable
costs of such remedy as additional rent. If Landlord is unable, or elects not to
remedy such condition,  then Landlord will have all of the remedies provided for
in this Lease in the event of a default by Tenant.

(e) Waiver of Subrogation.  Tenant's  property  insurance shall contain a clause
whereby the insurer waives all rights of recovery by way of subrogation  against
Landlord.  Tenant  shall also  obtain and  furnish  evidence  to Landlord of the
waiver by  Tenant's  worker's  compensation  insurance  carrier of all rights of
recovery by way of subrogation against Landlord.

20.   DAMAGE OR DESTRUCTION.

(a) Partial Destruction.  If the Premises or the Building are damaged by fire or
other casualty to an extent not exceeding  twenty-five percent (25%) of the full
replacement cost thereof,  and Landlord's  contractor  reasonably estimates in a
writing  delivered  to  Landlord  and  Tenant  that the  damage  thereto  may be
repaired,  reconstructed or restored to substantially its condition  immediately
prior to such damage within one hundred  eighty (180) days from the date of such
casualty,  and Landlord will receive insurance proceeds  sufficient to cover the
costs of such repairs,  reconstruction and restoration  (including proceeds from
Tenant and/or Tenant's insurance which Tenant is required to deliver to Landlord
pursuant to subparagraph 20(e) below to cover Tenant's  obligation for the costs
of  repair,  reconstruction  and  restoration  of  any  portion  of  the  Tenant
Improvements  and any  Alterations  for which Tenant is  responsible  under this
Lease), then Landlord agrees to commence and proceed diligently with the work of
repair,  reconstruction  and  restoration  and this Lease will  continue in full
force and effect.

(b)  Substantial  Destruction.  Any damage or destruction to the Premises or the
Building  which  Landlord is not  obligated to repair  pursuant to  subparagraph
20(a)  above  will be  deemed  a  substantial  destruction.  In the  event  of a
substantial  destruction,  Landlord may elect to either (i) repair,  reconstruct
and  restore  the  portion  of the  Building  or the  Premises  damaged  by such
casualty,  in which  case this  Lease will  continue  in full force and  effect,
subject to Tenant's  termination right contained in subparagraph 20(d) below; or
(ii)  terminate  this Lease  effective  as of the date which is thirty (30) days
after Tenant's receipt of Landlord's election to so terminate.

(c) Notice.  Under any of the conditions of subparagraphs  20(a) or 20(b) above,
Landlord  agrees to give written  notice to Tenant of its intention to repair or
terminate,  as permitted in such  paragraphs,  within the earlier of thirty (30)
days  after  the  occurrence  of such  casualty,  or  fifteen  (15)  days  after
Landlord's  receipt of the estimate from  Landlord's  contractor (the applicable
time period to be referred to herein as the "Notice Period").

(d) Tenant's  Termination Rights. If Landlord elects to repair,  reconstruct and
restore  pursuant  to  subparagraph  20(b)(i)  hereinabove,  and  if  Landlord's
contractor  estimates  that as a result of such damage,  Tenant  cannot be given
reasonable  use of and access to the Premises  within two hundred  seventy (270)
days  after the date of such  damage,  then  Tenant  may  terminate  this  Lease
effective upon delivery of written notice to Landlord within ten (10) days after
Landlord delivers notice to Tenant of its election to so repair,  reconstruct or
restore.

                                      -17-
 38

(e)  Tenant's  Costs  and  Insurance  Proceeds.  In the  event of any  damage or
destruction of all or any part of the Premises, Tenant agrees to immediately (i)
notify  Landlord  thereof,  and (ii) deliver to Landlord all property  insurance
proceeds received by Tenant with respect to any Tenant Improvements installed by
or at the  cost of  Tenant  and any  Alterations,  but  excluding  proceeds  for
Tenant's furniture,  fixtures, equipment and other personal property, whether or
not this Lease is  terminated  as  permitted  in this  Paragraph  20, and Tenant
hereby  assigns to Landlord all rights to receive such insurance  proceeds.  If,
for any reason  (including  Tenant's  failure to obtain  insurance  for the full
replacement  cost of any  Tenant  Improvements  installed  by or at the  cost of
Tenant and any Alterations from any and all casualties), Tenant fails to receive
insurance proceeds covering the full replacement cost of any Tenant Improvements
installed  by or at the cost of Tenant and any  Alterations  which are  damaged,
Tenant will be deemed to have  self-insured  the replacement cost of such items,
and upon any damage or destruction thereto,  Tenant agrees to immediately pay to
Landlord the full  replacement cost of such items,  less any insurance  proceeds
actually received by Landlord from Landlord's or Tenant's insurance with respect
to such  items.

(f) Abatement of Rent. In the event of any damage, repair, reconstruction and/or
restoration  described in this Paragraph 20, rent will be abated or reduced,  as
the case may be, from the date of such casualty,  in proportion to the degree to
which  Tenant's  use of the  Premises is  impaired  during such period of repair
until  such  use  is  restored.   Except  for  abatement  of  rent  as  provided
hereinabove, Tenant will not be entitled to any compensation or damages for loss
of, or interference with,  Tenant's business or use or access of all or any part
of the  Premises or for lost profits or any other  consequential  damages of any
kind or nature,  which result from any such damage,  repair,  reconstruction  or
restoration.

(g) Inability to Complete. Notwithstanding anything to the contrary contained in
this  Paragraph  20, if Landlord is obligated  or elects to repair,  reconstruct
and/or restore the damaged  portion of the Building or the Premises  pursuant to
subparagraphs  20(a) or 20(b)(i)  above,  but is delayed  from  completing  such
repair,  reconstruction  and/or  restoration beyond the date which is sixty (60)
days after the date estimated by Landlord's contractor for completion thereof by
reason of any  causes  (other  than  delays  caused by Tenant,  its  subtenants,
employees,  agents or  contractors  or delays  which are beyond  the  reasonable
control of Landlord as  described in Paragraph 33 which delays in no event shall
exceed a total of ninety (90) days), then either Landlord or Tenant may elect to
terminate  this Lease upon ten (10) days prior written notice given to the other
after the expiration of such sixty (60) day period.

(h) Damage Near End of Term.  Landlord  and Tenant  shall each have the right to
terminate this Lease if any damage to the Premises occurs during the last twelve
(12) months of the Term of this Lease where Landlord's contractor estimates in a
writing  delivered  to Landlord  and Tenant that the repair,  reconstruction  or
restoration of such damage cannot be completed  within sixty (60) days after the
date of such  casualty.  If either party  desires to terminate  this Lease under
this  subparagraph  20(h), it shall provide written notice to the other party of
such  election  within ten (10) days after  receipt of  Landlord's  contractor's
repair estimates.

(i) Waiver of  Termination  Right.  Landlord and Tenant agree that the foregoing
provisions  of this  Paragraph  20 are to govern  their  respective  rights  and
obligations in the event of any damage or  destruction  and supersede and are in
lieu  of the  provisions  of  any  applicable  law,  statute,  ordinance,  rule,
regulation, order or ruling now or hereafter in force which provide remedies for
damage or destruction of leased premises (including,  without limitation, to the
extent the Premises are located in  California,  the  provisions  of  California
Civil Code Section 1932,  Subsection  2, and Section 1933,  Subsection 4 and any
successor statute or laws of a similar nature).

(j) Termination.  Upon any termination of this Lease under any of the provisions
of this Paragraph 20, the parties will be released without further obligation to
the other from the date  possession of the Premises is  surrendered  to Landlord
except for items which have accrued and are unpaid as of the date of termination
and matters  which are to survive any  termination  of this Lease as provided in
this Lease.

21.   EMINENT DOMAIN.

(a) Substantial  Taking.  If the whole of the Premises,  or such part thereof as
shall  substantially  interfere with Tenant's use and occupancy of the Premises,
as contemplated  by this Lease, is taken for any public or quasi-public  purpose
by any lawful  power or  authority  by exercise  of the right of  appropriation,
condemnation  or eminent  domain,  or sold to prevent such taking,  either party
will have the right to terminate this Lease  effective as of the date possession
is  required  to be  surrendered  to  such  authority.  Further,  if  more  than
twenty-five  percent (25%) of the parking facilities  servicing the Building are
taken for public or  quasi-public  purposes by any lawful  power or authority by
exercise of the right of  appropriation,  condemnation  or eminent  domain,  and
Landlord does not provide reasonable  substitute parking within ninety (90) days
of such  appropriation,  Tenant  shall  have the right to  terminate  this Lease
effective as of the expiration of such ninety (90) day period.

                                      -18-
 39

(b) Partial Taking;  Abatement of Rent. In the event of a taking of a portion of
the  Premises  which does not  substantially  interfere  with  Tenant's  use and
occupancy of the Premises,  then, neither party will have the right to terminate
this Lease and Landlord will thereafter proceed to make a functional unit of the
remaining  portion of the  Premises  (but only to the extent  Landlord  receives
proceeds therefor from the condemning  authority),  and rent will be abated with
respect to the part of the  Premises  which  Tenant is deprived of on account of
such taking. Notwithstanding the immediately preceding sentence to the contrary,
if any part of the  Building or the  Development  is taken  (whether or not such
taking substantially interferes with Tenant's use of the Premises), Landlord may
terminate  this Lease upon  thirty (30) days prior  written  notice to Tenant if
Landlord also  terminates  the leases of the other tenants of the Building which
are leasing comparably sized space for comparable lease terms.

(c)  Condemnation  Award.  In connection  with any taking of the Premises or the
Building,  Landlord  will be entitled to receive the entire  amount of any award
which may be made or given in such taking or condemnation,  without deduction or
apportionment  for  any  estate  or  interest  of  Tenant,  it  being  expressly
understood  and  agreed by Tenant  that no  portion  of any such  award  will be
allowed or paid to Tenant for any so-called bonus or excess value of this Lease,
and such bonus or excess  value will be the sole  property of  Landlord.  Tenant
agrees not to assert any claim against  Landlord or the taking authority for any
compensation  because of such  taking  (including  any claim for bonus or excess
value of this  Lease);  provided,  however,  if any  portion of the  Premises is
taken, Tenant will have the right to recover from the condemning  authority (but
not from Landlord) any compensation as may be separately  awarded or recoverable
by Tenant for the taking of Tenant's  furniture,  fixtures,  equipment and other
personal property within the Premises, for Tenant's relocation expenses, and for
any loss of  goodwill  or other  damage to  Tenant's  business by reason of such
taking.

(d) Temporary Taking. In the event of taking of the Premises or any part thereof
for temporary use, (i) this Lease will remain  unaffected  thereby and rent will
abate for the duration of the taking in proportion to the extent Tenant's use of
the Premises is interfered  with,  and (ii) Landlord will be entitled to receive
such  portion or portions of any award made for such use  provided  that if such
taking remains in force at the expiration or earlier  termination of this Lease,
Tenant  will  then  pay to  Landlord  a sum  equal  to the  reasonable  cost  of
performing Tenant's  obligations under Paragraph 11 with respect to surrender of
the Premises and upon such payment Tenant will be excused from such obligations.
For purpose of this subparagraph 21(d), a temporary taking shall be defined as a
taking for a period of ninety (90) days or less.

22.   DEFAULTS AND REMEDIES.

(a) Defaults.  The occurrence of any one or more of the following events will be
deemed a default by  Tenant:

(i) The failure by Tenant to make any payment of rent or additional  rent or any
other payment  required to be made by Tenant  hereunder,  as and when due, where
such  failure  continues  for a period of ten (10)  days  after  written  notice
thereof from Landlord to Tenant; provided, however, that any such notice will be
in lieu of, and not in addition to, any notice  required  under  applicable  law
(including,  without  limitation,  to the extent  the  Premises  are  located in
California,  the provisions of California Code of Civil  Procedure  Section 1161
regarding unlawful detainer actions or any successor statute or law of a similar
nature).

(ii) The  failure by Tenant to observe or perform  any of the express or implied
covenants  or  provisions  of this Lease to be observed or  performed by Tenant,
other than as specified in  subparagraph  22(a)(i) or above,  where such failure
continues (where no other period of time is expressly  provided) for a period of
thirty (30) days after  written  notice  thereof  from  Landlord to Tenant.  The
provisions  of any such notice  will be in lieu of, and not in addition  to, any
notice required under  applicable law  (including,  without  limitation,  to the
extent  the  Premises  are  located  in  California,  California  Code of  Civil
Procedure  Section 1161 regarding  unlawful  detainer  actions and any successor
statute or similar  law).  If the nature of  Tenant's  default is such that more
than ten (10) days are reasonably required for its cure, then Tenant will not be
deemed to be in default if Tenant, with Landlord's  concurrence,  commences such
cure within such ten (10) day period and thereafter  diligently  prosecutes such
cure to completion.

                                      -19-
 40

(iii) (A) The  making by Tenant of any  general  assignment  for the  benefit of
creditors;  (B) the filing by or against  Tenant of a  petition  to have  Tenant
adjudged a bankrupt or a petition for  reorganization  or arrangement  under any
law relating to  bankruptcy  (unless,  in the case of a petition  filed  against
Tenant,  the same is dismissed within sixty (60) days); (C) the appointment of a
trustee or receiver to take possession of  substantially  all of Tenant's assets
located at the Premises or of Tenant's interest in this Lease,  where possession
is not  restored  to Tenant  within  thirty  (30) days;  or (D) the  attachment,
execution or other  judicial  seizure of  substantially  all of Tenant's  assets
located at the Premises or of Tenant's interest in this Lease where such seizure
is not discharged within thirty (30) days.

(b) Landlord's Remedies;  Termination. In the event of any default by Tenant, in
addition to any other  remedies  available to Landlord at law or in equity under
applicable law (including,  without  limitation,  to the extent the Premises are
located  in  California,  the  remedies  of Civil  Code  Section  1951.4 and any
successor  statute or similar law),  Landlord will have the immediate  right and
option to terminate this Lease and all rights of Tenant  hereunder.  If Landlord
elects to terminate this Lease then, to the extent  permitted  under  applicable
law,  Landlord may recover from Tenant (i) The worth at the time of award of any
unpaid rent which had been earned at the time of such termination; plus (ii) the
worth at the time of award of the  amount by which the unpaid  rent which  would
have been earned after termination until the time of award exceeds the amount of
such rent loss that Tenant proves could have been reasonably avoided; plus (iii)
the worth at the time of award of the  amount by which the  unpaid  rent for the
balance of the Term after the time of award exceeds the amount of such rent loss
that Tenant  proves  could be  reasonably  avoided;  plus (iv) any other  amount
necessary to  compensate  Landlord for all the detriment  proximately  caused by
Tenant's  failure to perform its  obligations  under this Lease or which, in the
ordinary  course of things,  results  therefrom  including,  but not limited to:
attorneys' fees and costs;  brokers'  commissions;  the costs of  refurbishment,
alterations,  renovation and repair of the Premises,  and removal (including the
repair of any damage  caused by such  removal)  and  storage  (or  disposal)  of
Tenant's  personal  property,  equipment,  fixtures,   Alterations,  the  Tenant
Improvements  and any other items which  Tenant is required  under this Lease to
remove but does not remove, as well as the unamortized value of any reduced rent
(amortized over the Original Term, with interest  thereon at the Interest Rate),
reduced  rent,  free  parking,  reduced  rate parking or other costs or economic
concessions  provided,  paid,  granted or incurred by Landlord  pursuant to this
Lease. The unamortized  value of such concessions  shall be determined by taking
the total value of such  concessions and  multiplying  such value by a fraction,
the numerator of which is the number of months of the Lease Term not yet elapsed
as of the date on which the Lease is terminated, and the denominator of which is
the total number of months of the Lease Term. As used in subparagraphs  22(b)(i)
and  22(b)(ii)  above,  the "worth at the time of award" is computed by allowing
interest at the Interest Rate. As used in  subparagraph  22(b)(iii)  above,  the
"worth at the time of award"  is  computed  by  discounting  such  amount at the
discount rate of the Federal  Reserve Bank of San Francisco at the time of award
plus one percent (1%).

(c) Landlord's Remedies; Re-Entry Rights. In the event of any default by Tenant,
in addition to any other remedies available to Landlord under this Lease, at law
or in equity,  Landlord  will also have the right,  with or without  terminating
this Lease,  to re-enter the  Premises and remove all persons and property  from
the Premises;  such property may be removed and stored in a public  warehouse or
elsewhere and/or disposed of at the sole cost and expense of and for the account
of Tenant in accordance with the provisions of subparagraph  13(h) of this Lease
or any other  procedures  permitted  by  applicable  law.  No re-entry or taking
possession of the Premises by Landlord pursuant to this subparagraph  22(c) will
be construed as an election to terminate  this Lease unless a written  notice of
such intention is given to Tenant or unless the  termination  thereof is decreed
by a court of competent jurisdiction.

                                      -20-
 41

(d) Landlord's Remedies; Re-Letting. In the event of the vacation or abandonment
of the Premises by Tenant or in the event that  Landlord  elects to re-enter the
Premises or takes  possession  of the Premises  pursuant to legal  proceeding or
pursuant  to any notice  provided  by law,  then if  Landlord  does not elect to
terminate this Lease,  Landlord may from time to time, without  terminating this
Lease,  either  recover all rent as it becomes due or relet the  Premises or any
part  thereof  on terms and  conditions  as  Landlord  in its sole and  absolute
discretion may deem advisable with the right to make  alterations and repairs to
the Premises in connection with such reletting.  If Landlord elects to relet the
Premises,  then rents  received by Landlord from such reletting will be applied:
first,  to the payment of any  indebtedness  other than rent due hereunder  from
Tenant to Landlord; second, to the payment of any cost of such reletting; third,
to the  payment  of the cost of any  alterations  and  repairs  to the  Premises
incurred in connection with such reletting;  fourth,  to the payment of rent due
and unpaid  hereunder  and the  residue,  if any,  will be held by Landlord  and
applied  to  payment  of  future  rent as the same may  become  due and  payable
hereunder. Should that portion of such rents received from such reletting during
any month,  which is applied to the payment of rent hereunder,  be less than the
rent payable  during that month by Tenant  hereunder,  then Tenant agrees to pay
such deficiency to Landlord  immediately upon demand therefor by Landlord.  Such
deficiency will be calculated and paid monthly.

(e) Landlord's Remedies; Performance for Tenant. All covenants and agreements to
be  performed by Tenant under any of the terms of this Lease are to be performed
by Tenant at Tenant's  sole cost and expense and without any  abatement of rent.
If Tenant  fails to pay any sum of money owed to any party other than  Landlord,
for which it is liable under this Lease, or if Tenant fails to perform any other
act on its part to be performed  hereunder,  and such failure  continues for ten
(10) days after notice  thereof by Landlord,  Landlord may,  without  waiving or
releasing Tenant from its  obligations,  but shall not be obligated to, make any
such  payment or perform any such other act to be made or  performed  by Tenant.
Tenant agrees to reimburse Landlord upon demand for all sums so paid by Landlord
and all  necessary  incidental  costs,  together  with  interest  thereon at the
Interest  Rate,  from the date of such payment by Landlord  until  reimbursed by
Tenant.  This  remedy  shall be in  addition  to any  other  right or  remedy of
Landlord set forth in this Paragraph 22.

(f) Late Payment.  If Tenant fails to pay any  installment  of rent within seven
(7) days of when due or if  Tenant  fails to make any  other  payment  for which
Tenant is obligated  under this Lease  within  seven (7) days of when due,  such
late amount will accrue  interest at the Interest  Rate and Tenant agrees to pay
Landlord  as  additional  rent such  interest  on such amount from the date such
amount becomes due until such amount is paid. In addition,  Tenant agrees to pay
to Landlord  concurrently  with such late payment amount,  as additional rent, a
late charge equal to three percent (3%) of the amount due to compensate Landlord
for the extra  costs  Landlord  will  incur as a result  of such  late  payment.
Notwithstanding  the foregoing,  Landlord hereby agrees to waive the late charge
applicable  to the  first  instance  in which  Tenant  fails to  timely  pay any
installment  of rent or other  payment for which Tenant is obligated  under this
Lease during any twelve (12) month  period.  The parties agree that (i) it would
be impractical  and extremely  difficult to fix the actual damage  Landlord will
suffer in the event of Tenant's late payment, (ii) such interest and late charge
represents a fair and  reasonable  estimate of the detriment  that Landlord will
suffer by reason of late  payment by Tenant,  and (iii) the  payment of interest
and late charges are distinct and separate in that the payment of interest is to
compensate Landlord for the use of Landlord's money by Tenant, while the payment
of  late  charges  is  to  compensate   Landlord  for   Landlord's   processing,
administrative  and other  costs  incurred  by  Landlord as a result of Tenant's
delinquent  payments.  Acceptance  of any such interest and late charge will not
constitute a waiver of the Tenant's  default with respect to the overdue amount,
or  prevent  Landlord  from  exercising  any of the other  rights  and  remedies
available to Landlord.  If Tenant incurs a late charge more than three (3) times
in any period of twelve (12) months during the Lease Term, then, notwithstanding
that Tenant  cures the late  payments  for which such late  charges are imposed,
Landlord  will  have  the  right  to  require  Tenant   thereafter  to  pay  all
installments of Monthly Base Rent quarterly in advance  throughout the remainder
of the Lease Term.

(g) Landlord's  Security  Interest.  Tenant hereby grants to Landlord a lien and
security  interest on all property of Tenant now or hereafter  placed in or upon
the Premises including, but not limited to, all fixtures, machinery,  equipment,
furnishings  and other  articles of personal  property,  and all proceeds of the
sale or other disposition of such property  (collectively,  the "Collateral") to
secure the payment of all rent to be paid by Tenant pursuant to this Lease. Such
lien and security  interest shall be in addition to any landlord's lien provided
by law. This Lease shall  constitute a security  agreement  under the Commercial
Code of the  State so that  Landlord  shall  have  and may  enforce  a  security
interest in the Collateral.  Tenant agrees to execute as debtor and deliver such
financing  statement or statements and any further documents as Landlord may now
or hereafter  reasonably  request to protect such security  interest pursuant to
such  code.  Landlord  may  also at any  time  file a copy of  this  Lease  as a
financing statement. Landlord, as secured party, shall be entitled to all rights
and  remedies  afforded  as secured  party  under such  code,  which  rights and
remedies shall be in addition to Landlord's  liens and rights provided by law or
by the other terms and provisions of this Lease.

                                      -21-
 42

(h) Rights and Remedies Cumulative. All rights, options and remedies of Landlord
contained in this Lease will be construed and held to be cumulative,  and no one
of them will be  exclusive of the other,  and  Landlord  shall have the right to
pursue any one or all of such  remedies or any other  remedy or relief which may
be provided by law or in equity, whether or not stated in this Lease. Nothing in
this  Paragraph  22 will  be  deemed  to  limit  or  otherwise  affect  Tenant's
indemnification of Landlord pursuant to any provision of this Lease.

23.  LANDLORD'S  DEFAULT.  Landlord will not be in default in the performance of
any  obligation  required to be  performed  by Landlord  under this Lease unless
Landlord  fails to perform  such  obligation  within  thirty (30) days after the
receipt of written notice from Tenant specifying in detail Landlord's failure to
perform;  provided however,  that if the nature of Landlord's obligation is such
that more than thirty (30) days are required for performance, then Landlord will
not be deemed in default if it  commences  such  performance  within such thirty
(30) day period and thereafter  diligently pursues the same to completion.  Upon
any default by Landlord,  Tenant may exercise any of its rights  provided at law
or in equity,  subject to the limitations on liability set forth in Paragraph 35
of this Lease.

24.   ASSIGNMENT AND SUBLETTING.

(a) Restriction on Transfer.  Except as expressly provided in this Paragraph 24,
Tenant will not,  either  voluntarily or by operation of law, assign or encumber
this Lease or any interest herein or sublet the Premises or any part thereof, or
permit the use or  occupancy of the Premises by any party other than Tenant (any
such assignment, encumbrance, sublease or the like will sometimes be referred to
as a "Transfer"),  without the prior written consent of Landlord,  which consent
Landlord will not unreasonably withhold.

(b) Corporate and Partnership  Transfers.  For purposes of this Paragraph 24, if
Tenant is a corporation,  partnership or other entity, any transfer, assignment,
encumbrance or hypothecation of twenty-five  percent (25%) or more (individually
or in the  aggregate) of any stock or other  ownership  interest in such entity,
and/or any transfer, assignment, hypothecation or encumbrance of any controlling
ownership or voting interest in such entity,  will be deemed a Transfer and will
be subject to all of the restrictions and provisions contained in this Paragraph
24.  Notwithstanding the foregoing,  the immediately preceding sentence will not
apply  to any  transfers  of  stock  of  Tenant  if  Tenant  is a  publicly-held
corporation  and such stock is transferred  publicly over a recognized  security
exchange or over-the-counter market.

(c)  Permitted  Controlled  Transfers.  Notwithstanding  the  provisions of this
Paragraph  24 to the  contrary,  Tenant  may  assign  this  Lease or sublet  the
Premises or any  portion  thereof  ("Permitted  Transfer"),  without  Landlord's
consent and without extending any sublease  termination  option to Landlord,  to
any parent, subsidiary or affiliate corporation which controls, is controlled by
or is under common control with Tenant,  or to any corporation  resulting from a
merger or consolidation  with Tenant,  or to any person or entity which acquires
all the assets of Tenant's  business as a going  concern,  provided that: (i) at
least twenty (20) days prior to such assignment or sublease,  Tenant delivers to
Landlord the financial statements and other financial and background information
of the assignee or sublessee  described in subparagraph  24(d) below; (ii) if an
assignment,  the assignee assumes, in full, the obligations of Tenant under this
Lease (or if a  sublease,  the  sublessee  of a portion of the  Premises or Term
assumes, in full, the obligations of Tenant with respect to such portion); (iii)
the  financial  net worth of the  assignee  or  sublessee  as of the time of the
proposed  assignment or sublease equals or exceeds that of Tenant as of the date
of execution of this Lease;  (iv) Tenant  remains fully liable under this Lease;
and (v)  the use of the  Premises  under  Paragraph  8  remains  unchanged.

(d)  Transfer  Notice.  If Tenant  desires to effect a  Transfer,  then at least
thirty  (30) days  prior to the date when  Tenant  desires  the  Transfer  to be
effective  (the "Transfer  Date"),  Tenant agrees to give Landlord a notice (the
"Transfer  Notice"),  stating  the name,  address and  business of the  proposed
assignee,  sublessee or other transferee  (sometimes  referred to hereinafter as
"Transferee"),  reasonable  information  (including  references)  concerning the
character,  ownership,  and financial condition of the proposed Transferee,  the
Transfer Date, any ownership or commercial  relationship  between Tenant and the
proposed  Transferee,  and the  consideration  and all other  material terms and
conditions  of the  proposed  Transfer,  all in  such  detail  as  Landlord  may
reasonably  require.  If Landlord  reasonably  requests  additional  detail, the
Transfer Notice will not be deemed to have been received until Landlord receives
such additional  detail, and Landlord may withhold consent to any Transfer until
such information is provided to it.

                                      -22-
 43

(e) Landlord's  Options.  Within fifteen (15) days of Landlord's  receipt of any
Transfer Notice, and any additional information requested by Landlord concerning
the proposed Transferee's  financial  responsibility,  Landlord will elect to do
one of the  following  (i) consent to the  proposed  Transfer;  (ii) refuse such
consent,  which  refusal  shall  be on  reasonable  grounds  including,  without
limitation, those set forth in subparagraph 24(f) below; or (iii) terminate this
Lease in the event of a proposed  assignment of this Lease or a subletting as to
the  entire  Premises  for  substantially  all of  the  remaining  Term,  and to
recapture the Premises for reletting by Landlord.

(f)  Reasonable  Disapproval.   Landlord  and  Tenant  hereby  acknowledge  that
Landlord's  disapproval of any proposed Transfer pursuant to subparagraph  24(e)
will be  deemed  reasonably  withheld  if  based  upon  any  reasonable  factor,
including,  without limitation,  any or all of the following factors: (i) if the
Building is less than seventy percent (70%) occupied,  if the net effective rent
payable by the  Transferee  (adjusted  on a rentable  square foot basis) is less
than the net effective  rent then being quoted by Landlord for new leases in the
Building for  comparable  size space for a comparable  period of time;  (ii) the
proposed Transferee is a governmental  entity; (iii) the portion of the Premises
to be sublet or assigned is irregular in shape with inadequate  means of ingress
and egress;  (iv) the use of the Premises by the Transferee (A) is not permitted
by the use  provisions  in Paragraph 8 hereof,  (B) violates any  exclusive  use
granted by Landlord to another tenant in the Building,  or (C) otherwise poses a
risk of increased liability to Landlord; (v) the Transfer would likely result in
a  significant  and  inappropriate  increase in the use of the parking  areas or
Development  Common Areas by the  Transferee's  employees  or  visitors,  and/or
significantly  increase the demand upon utilities and services to be provided by
Landlord  to the  Premises;  (vi) the  Transferee  does  not have the  financial
capability  to fulfill the  obligations  imposed by the Transfer and this Lease;
(vii) the Transferee is not in Landlord's  reasonable  opinion  consistent  with
Landlord's  desired  tenant  mix; or (viii) the  Transferee  poses a business or
other economic risk which Landlord deems unacceptable.

(g) Additional Conditions.  A condition to Landlord's consent to any Transfer of
this Lease will be the delivery to Landlord of a true copy of the fully executed
instrument of assignment, sublease, transfer or hypothecation,  and, in the case
of an  assignment,  the  delivery to Landlord  of an  agreement  executed by the
Transferee in form and substance  reasonably  satisfactory to Landlord,  whereby
the Transferee assumes and agrees to be bound by all of the terms and provisions
of this Lease and to perform all of the  obligations of Tenant  hereunder.  As a
condition for granting its consent to any  assignment or sublease,  Landlord may
require that the assignee or sublessee  remit  directly to Landlord on a monthly
basis, all monies due to Tenant by said assignee or sublessee. As a condition to
Landlord's  consent to any  sublease,  such  sublease  must  provide  that it is
subject and  subordinate to this Lease and to all  mortgages;  that Landlord may
enforce the provisions of the sublease,  including  collection of rent;  that in
the  event of  termination  of this  Lease  for any  reason,  including  without
limitation a voluntary  surrender  by Tenant,  or in the event of any reentry or
repossession  of the Premises by Landlord,  Landlord may, at its option,  either
(i)  terminate  the  sublease,  or (ii)  take over all of the  right,  title and
interest  of  Tenant,  as  sublessor,  under such  sublease,  in which case such
sublessee will attorn to Landlord,  but that nevertheless  Landlord will not (1)
be liable for any previous act or omission of Tenant under such sublease, (2) be
subject to any defense or offset  previously  accrued in favor of the  sublessee
against  Tenant,  or (3) be bound by any previous  modification  of any sublease
made  without  Landlord's  written  consent,  or by any previous  prepayment  by
sublessee of more than one month's rent.

(h) Excess Rent. If Landlord  consents to any  assignment of this Lease,  Tenant
agrees to pay to Landlord,  as additional  rent, fifty percent (50%) of all sums
and other consideration payable to and for the benefit of Tenant by the assignee
on account of the assignment,  as and when such sums and other consideration are
due and payable by the assignee to or for the benefit of Tenant (or, if Landlord
so requires,  and without any release of Tenant's liability for the same, Tenant
agrees  to  instruct  the  assignee  to pay such  sums and  other  consideration
directly  to  Landlord).  If for any  sublease,  Tenant  receives  rent or other
consideration,  either initially or over the term of the sublease,  in excess of
the rent fairly  allocable  to the portion of the  Premises  which is  subleased
based on square  footage,  Tenant agrees to pay to Landlord as  additional  rent
fifty  percent  (50%)  of the  excess  of each  such  payment  of rent or  other
consideration  received by Tenant  promptly  after its receipt.  In  calculating
excess rent or other  consideration  which may be payable to Landlord under this
paragraph, Tenant will be entitled to deduct commercially reasonable third party
brokerage  commissions  and  attorneys'  fees and other amounts  reasonably  and
actually  expended by Tenant in connection with such assignment or subletting if
acceptable written evidence of such expenditures is provided to Landlord.

                                      -23-

(i) Termination  Rights. If Tenant requests Landlord's consent to any assignment
of this Lease or a subletting of all the Premises for  substantially  all of the
remaining Term, Landlord will have the right, as provided in subparagraph 24(e),
to terminate this Lease  effective as of the date Tenant proposes to assign this
Lease or sublet the entire  Premises.  Landlord will  exercise such  termination
right,  if at all, by giving written notice to Tenant within thirty (30) days of
receipt by Landlord of the financial responsibility information required by this
Paragraph 24. Tenant  understands and acknowledges  that the option, as provided
in this  Paragraph 24, to terminate  this Lease in the event Tenant  proposes to
sublet  the entire  Premises  for  substantially  all of the  remaining  Term or
proposes to assign this Lease rather than approve such  subletting or assignment
is a material inducement for Landlord's agreeing to lease the Premises to Tenant
upon the terms and conditions herein set forth.

(j) No Release.  No Transfer will release Tenant of Tenant's  obligations  under
this  Lease or alter  the  primary  liability  of  Tenant to pay the rent and to
perform all other obligations to be performed by Tenant hereunder.  Landlord may
require that any Transferee  remit directly to Landlord on a monthly basis,  all
monies  due  Tenant  by said  Transferee.  However,  the  acceptance  of rent by
Landlord  from any other person will not be deemed to be a waiver by Landlord of
any  provision  hereof.  Consent by Landlord to one Transfer  will not be deemed
consent to any subsequent Transfer. In the event of default by any Transferee of
Tenant or any successor of Tenant in the performance of any of the terms hereof,
Landlord may proceed directly against Tenant without the necessity of exhausting
remedies  against  such  Transferee  or  successor.   Landlord  may  consent  to
subsequent   assignments   of  this  Lease  or   sublettings  or  amendments  or
modifications to this Lease with assignees of Tenant,  without notifying Tenant,
or any successor of Tenant,  and without  obtaining its or their consent thereto
and any such actions will not relieve Tenant of liability under this Lease.

(k) Administrative and Attorneys' Fees. If Tenant effects a Transfer or requests
the  consent of  Landlord  to any  Transfer  (whether  or not such  Transfer  is
consummated),  then, upon demand, Tenant agrees to pay Landlord a non-refundable
administrative fee of Two Hundred Fifty Dollars  ($250.00),  plus any reasonable
attorneys'  and  paralegal  fees  incurred by Landlord in  connection  with such
Transfer or request for consent  (whether  attributable  to Landlord's  in-house
attorneys  or  paralegals  or  otherwise)  not to  exceed  One  Hundred  Dollars
($100.00) for each one thousand  (1,000)  rentable square feet of area contained
within the Premises or portion  thereof to be assigned or sublet.  Acceptance of
the Two Hundred Fifty Dollar ($250.00)  administrative fee and/or  reimbursement
of Landlord's  attorneys' and paralegal fees will in no event obligate  Landlord
to consent to any  proposed  Transfer.

25.  SUBORDINATION.  At the election of Landlord or any mortgagee or beneficiary
with a deed of trust  encumbering  the Building and/or the  Development,  or any
lessor of a ground or underlying lease with respect to the Building,  this Lease
will be  subject  and  subordinate  at all times to:  (i) all  ground  leases or
underlying  leases which may now exist or hereafter  be executed  affecting  the
Building; and (ii) the lien of any mortgage or deed of trust which may now exist
or hereafter be executed for which the Building,  the  Development or any leases
thereof, or Landlord's interest and estate in any of said items, is specified as
security;  provided,  however, as a condition to the subordination of this Lease
to any ground lease,  mortgage or deed of trust, the applicable ground lessor or
mortgagee shall agree that Tenant's right to possession of the Premises will not
be  disturbed   as  long  as  Tenant  is  not  in  default   under  this  Lease.
Notwithstanding  the foregoing,  Landlord  reserves the right to subordinate any
such ground leases or underlying  leases or any such liens to this Lease. If any
such ground  lease or  underlying  lease  terminates  for any reason or any such
mortgage or deed of trust is foreclosed  or a conveyance in lieu of  foreclosure
is made for any reason,  at the  election of  Landlord's  successor in interest,
Tenant  agrees to attorn to and  become the  tenant of such  successor  in which
event Tenant's right to possession of the Premises will not be disturbed as long
as Tenant is not in default  under this Lease.  Tenant  hereby waives its rights
under any law which gives or purports to give Tenant any right to  terminate  or
otherwise adversely affect this Lease and the obligations of Tenant hereunder in
the event of any such  foreclosure  proceeding  or sale.  Tenant  covenants  and
agrees  to  execute  and  deliver,  upon  demand  by  Landlord  and in the  form
reasonably  required  by  Landlord,  any  additional  documents  evidencing  the
priority or subordination of this Lease and Tenant's  attornment  agreement with
respect to any such ground  lease or  underlying  leases or the lien of any such
mortgage or deed of trust. If Tenant fails to sign and return any such documents
within ten (10) days of receipt, Tenant will be in default hereunder.

                                      -24-

26.   ESTOPPEL CERTIFICATE.

(a) Tenant's  Obligations.  Within ten (10) days  following any written  request
which Landlord may make from time to time,  Tenant agrees to execute and deliver
to Landlord a statement,  in a form substantially similar to the form of Exhibit
"G"  attached  hereto or as may  reasonably  be required by  Landlord's  lender,
certifying:  (i) the date of commencement of this Lease; (ii) the fact that this
Lease is  unmodified  and in full  force  and  effect  (or,  if there  have been
modifications, that this Lease is in full force and effect, and stating the date
and  nature of such  modifications);  (iii) the date to which the rent and other
sums  payable  under this  Lease have been paid;  (iv) that there are no current
defaults  under this Lease by either  Landlord or Tenant  except as specified in
Tenant's statement; and (v) such other matters reasonably requested by Landlord.
Landlord  and  Tenant  intend  that any  statement  delivered  pursuant  to this
Paragraph  26 may be relied upon by any  mortgagee,  beneficiary,  purchaser  or
prospective purchaser of the Building or any interest therein.

(b) Tenant's  Failure to Deliver.  Tenant's  failure to deliver  such  statement
within such time will be  conclusive  upon Tenant (i) that this Lease is in full
force and effect, without modification except as may be represented by Landlord,
(ii) that there are no uncured  defaults in  Landlord's  performance,  and (iii)
that not more  than one (1)  month's  rent  has been  paid in  advance.  Without
limiting the  foregoing,  if Tenant fails to deliver any such  statement  within
such ten (10) day period,  Landlord may deliver to Tenant an additional  request
for such  statement and Tenant's  failure to deliver such  statement to Landlord
within ten (10) days after delivery of such additional request will constitute a
default under this Lease.  Tenant agrees to indemnify and protect  Landlord from
and  against any and all  claims,  damages,  losses,  liabilities  and  expenses
(including  attorneys' fees and costs)  attributable to any failure by Tenant to
timely  deliver any such  estoppel  certificate  to Landlord as required by this
Paragraph 26.

27.   INTENTIONALLY OMITTED.

28. RULES AND REGULATIONS.  Tenant agrees to faithfully  observe and comply with
the "Rules and Regulations", a copy of which is attached hereto and incorporated
herein  by  this   reference   as   Exhibit   "H",   and  all   reasonable   and
nondiscriminatory  modifications thereof and additions thereto from time to time
put into effect by  Landlord.  Landlord  agrees to use  reasonable  efforts (but
shall not be obligated to institute or threaten to institute any  litigation) to
cause other tenants of the Building and the Development to comply with the Rules
and  Regulations;  provided,  however,  that Landlord will not be responsible to
Tenant for the violation or  non-performance  by any other tenant or occupant of
the Building or the Development of any of the Rules and Regulations.

29.  MODIFICATION  AND CURE RIGHTS OF  LANDLORD'S  MORTGAGEES  AND LESSORS.

(a) Modifications.  If, in connection with Landlord's obtaining or entering into
any  financing  or  ground  lease  for  any  portion  of  the  Building  or  the
Development,  the lender or ground lessor requests  modifications to this Lease,
Tenant,  within  ten (10) days  after  request  therefor,  agrees to  execute an
amendment  to  this  Lease  incorporating  such  modifications,   provided  such
modifications are reasonable and do not increase the obligations of Tenant under
this Lease or adversely  affect the leasehold  estate  created by this Lease and
are otherwise reasonably acceptable to Tenant.

(b) Cure  Rights.  In the event of any default on the part of  Landlord,  Tenant
will give notice by registered or certified mail to any beneficiary of a deed of
trust or  mortgage  covering  the  Premises or ground  lessor of Landlord  whose
address  has  been  furnished  to  Tenant,  and  Tenant  agrees  to  offer  such
beneficiary,  mortgagee or ground  lessor a reasonable  opportunity  to cure the
default  (including with respect to any such  beneficiary or mortgagee,  time to
obtain  possession  of the Premises,  subject to this Lease and Tenant's  rights
hereunder,  by power of sale or a judicial  foreclosure,  if such  should  prove
necessary to effect a cure).

                                      -25-

30. DEFINITION OF LANDLORD. The term "Landlord" as used in this Lease, so far as
covenants  or  obligations  on the part of  Landlord  are  concerned,  means and
includes only the owner or owners, at the time in question,  of the fee title of
the Premises or the lessees under any ground lease,  if any. In the event of any
transfer,  assignment or other  conveyance or transfers of any such title (other
than a transfer for security purposes only),  Landlord herein named (and in case
of  any  subsequent  transfers  or  conveyances,   the  then  grantor)  will  be
automatically  relieved from and after the date of such transfer,  assignment or
conveyance  of all  liability as respects the  performance  of any  covenants or
obligations  on the part of Landlord  contained in this Lease  thereafter  to be
performed,  so long as the transferee  assumes in writing all such covenants and
obligations of Landlord  arising after the date of such  transfer.  Landlord and
Landlord's  transferees and assignees have the absolute right to transfer all or
any  portion of their  respective  title and  interest in the  Development,  the
Building, the Premises and/or this Lease without the consent of Tenant, and such
transfer or  subsequent  transfer  will not be deemed a violation on  Landlord's
part of any of the terms and conditions of this Lease.

31.  WAIVER.  The waiver by either party of any breach of any term,  covenant or
condition  herein  contained will not be deemed to be a waiver of any subsequent
breach of the same or any other term,  covenant or condition  herein  contained,
nor will any custom or  practice  which may  develop  between the parties in the
administration  of the terms  hereof be deemed a waiver of or in any way  affect
the right of either party to insist upon  performance in strict  accordance with
said terms. The subsequent  acceptance of rent or any other payment hereunder by
Landlord will not be deemed to be a waiver of any preceding  breach by Tenant of
any term,  covenant or condition of this Lease, other than the failure of Tenant
to pay the particular  rent so accepted,  regardless of Landlord's  knowledge of
such  preceding  breach at the time of acceptance of such rent. No acceptance by
Landlord  of a lesser sum than the basic rent and  additional  rent or other sum
then due will be deemed to be other than on account of the earliest  installment
of such rent or other amount due, nor will any  endorsement  or statement on any
check or any letter accompanying any check be deemed an accord and satisfaction,
and Landlord may accept such check or payment  without  prejudice to  Landlord's
right to recover the balance of such  installment  or other amount or pursue any
other remedy  provided in this Lease.  The consent or approval of Landlord to or
of any act by Tenant requiring Landlord's consent or approval will not be deemed
to waive or render  unnecessary  Landlord's  consent  or  approval  to or of any
subsequent similar acts by Tenant.

32.   PARKING.

(a) Grant of Parking  Rights.  So long as this  Lease is in effect and  provided
Tenant is not in  default  hereunder,  Landlord  grants to Tenant  and  Tenant's
Authorized  Users (as  defined  below) a license  to use the  number and type of
parking  permits  designated  in  subparagraph  1(s)  subject  to the  terms and
conditions of this Paragraph 32 and the Rules and Regulations  regarding parking
contained in Exhibit "H" attached  hereto.  Tenant  agrees to submit to Landlord
or, at Landlord's election,  directly to Landlord's parking operator with a copy
to  Landlord,  written  notice  in  a  form  reasonably  specified  by  Landlord
containing the names,  home and office addresses and telephone  numbers of those
persons  who are  authorized  by Tenant to use  Tenant's  parking  permits  on a
monthly basis  ("Tenant's  Authorized  Users") and shall use its best efforts to
identify each vehicle of Tenant's  Authorized  Users by make,  model and license
number.  Tenant agrees to deliver such notice prior to the beginning of the Term
of this Lease and to  periodically  update such notice as well as upon  specific
request by  Landlord  or  Landlord's  parking  operator  to  reflect  changes to
Tenant's  Authorized Users or their vehicles.

(b) Visitor Parking.  So long as this Lease is in effect,  Tenant's visitors and
guests will be entitled to use those specific parking areas which are designated
for short term visitor  parking and which are located within the surface parking
area(s),  if any,  and/or  within  the  parking  structure(s)  which  serve  the
Building.  During the Original Term of this Lease,  visitor parking will be made
available at no charge to Tenant's visitors and guests. Tenant, at its sole cost
and expense, may elect to validate such parking for its visitors and guests. All
such visitor parking will be on a non-exclusive,  in common basis with all other
visitors and guests of the Development.

                                      -26-
 47

(c) Use of  Parking  Permits.  Tenant  will  not use or  allow  any of  Tenant's
Authorized  Users  to use any  parking  permits  which  have  been  specifically
assigned  by Landlord to other  tenants or  occupants  or for other uses such as
visitor  parking or which have been  designated  by any  governmental  entity as
being  restricted  to certain  uses.  Tenant will not be entitled to increase or
reduce its parking privileges  applicable to the Premises during the Term of the
Lease except as follows: If at any time Tenant desires to increase or reduce the
number of parking permits allocated to it under the terms of this Lease,  Tenant
must notify Landlord in writing of such desire and Landlord will have the right,
in its sole and  absolute  discretion,  to either  (a)  approve  such  requested
increase  in the  number  of  parking  permits  allocated  to  Tenant  (with  an
appropriate  increase  to  the  additional  rent  payable  by  Tenant  for  such
additional permits based on the then prevailing parking rates), (b) approve such
requested decrease in the number of parking permits allocated to Tenant (with an
appropriate  reduction  in the  additional  rent  payable  by  Tenant  for  such
eliminated  parking permits based on the then prevailing  parking rates), or (c)
disapprove such requested  increase or decrease in the number of parking permits
allocated to Tenant.  Promptly  following  receipt of Tenant's  written request,
Landlord  will provide  Tenant with written  notice of its decision  including a
statement  of any  adjustments  to the  additional  rent  payable  by Tenant for
parking under the Lease, if applicable.

(d) General Provisions.  Except as otherwise expressly set forth in subparagraph
1(s),  Landlord reserves the right to set and increase monthly fees and/or daily
and hourly rates for parking privileges from time to time during the Term of the
Lease.  Landlord may assign any unreserved and unassigned parking permits and/or
make  all or any  portion  of  such  spaces  reserved,  if  Landlord  reasonably
determines  that it is necessary  for orderly and  efficient  parking or for any
other  reasonable  reason.  Failure to pay the rent for any  particular  parking
permits  or  failure  to  comply  with any terms and  conditions  of this  Lease
applicable  to parking may be treated by Landlord as a default  under this Lease
and, in addition to all other remedies available to Landlord under the Lease, at
law or in equity,  Landlord may elect to recapture such parking  permits for the
balance of the Term of this Lease if Tenant  does not cure such  failure  within
the  applicable  cure period set forth in  Paragraph  22 of this Lease.  In such
event, Tenant and Tenant's Authorized Users will be deemed visitors for purposes
of  parking  space use and will be  entitled  to use only  those  parking  areas
specifically  designated for visitor  parking  subject to all provisions of this
Lease  applicable  to such visitor  parking use.  Except in  connection  with an
assignment  or  sublease  expressly  permitted  under the  terms of this  Lease,
Tenant's  parking rights and privileges  described herein are personal to Tenant
and  may  not  be  assigned  or  transferred,  or  otherwise  conveyed,  without
Landlord's  prior written  consent,  which consent  Landlord may withhold in its
sole and absolute discretion.  In any event, under no circumstances may Tenant's
parking rights and  privileges be  transferred,  assigned or otherwise  conveyed
separate and apart from Tenant's interest in this Lease.

(e)  Cooperation  with Traffic  Mitigation  Measures.  Tenant  agrees to use its
reasonable, good faith efforts to cooperate in traffic mitigation programs which
may be  undertaken  by  Landlord  independently,  or in  cooperation  with local
municipalities or governmental agencies or other property owners in the vicinity
of the  Building.  Such  programs  may  include,  but  will not be  limited  to,
carpools,  vanpools and other ridesharing programs,  public and private transit,
flexible  work hours,  preferential  assigned  parking  programs and programs to
coordinate  tenants  within the  Development  with existing or proposed  traffic
mitigation programs.

(f) Parking Rules and  Regulations.  Tenant and Tenant's  Authorized Users shall
comply with all rules and regulations regarding parking set forth in Exhibit "H"
attached hereto and Tenant agrees to cause its employees, subtenants, assignees,
contractors,  suppliers,  customers  and  invitees to comply with such rules and
regulations.  Landlord  reserves  the right  from time to time to modify  and/or
adopt such other reasonable and non-discriminatory rules and regulations for the
parking  facilities  as it deems  reasonably  necessary for the operation of the
parking facilities.

33.  FORCE  MAJEURE.  If either  Landlord or Tenant is  delayed,  hindered in or
prevented from the performance of any act required under this Lease by reason of
strikes,  lock-outs,  labor troubles,  inability to procure standard  materials,
failure  of  power,  restrictive  governmental  laws,  regulations  or orders or
governmental action or inaction (including failure,  refusal or delay in issuing
permits,  approvals and/or  authorizations which is not the result of the action
or  inaction  of  the  party  claiming  such  delay),  riots,  civil  unrest  or
insurrection,  war, fire, earthquake,  flood or other natural disaster,  unusual
and  unforeseeable  delay  which  results  from an  interruption  of any  public
utilities  (e.g.,  electricity,  gas,  water,  telephone)  or other  unusual and
unforeseeable  delay not within the  reasonable  control of the party delayed in
performing work or doing acts required under the provisions of this Lease,  then
performance  of such act will be  excused  for the  period  of the delay and the
period  for the  performance  of any  such  act  will be  extended  for a period
equivalent to the period of such delay. The provisions of this Paragraph 33 will
not operate to excuse Tenant from prompt  payment of rent or any other  payments
required under the provisions of this Lease.

                                      -27-
 48

34. SIGNS. Prior to the Commencement Date,  Landlord will designate the location
on the Premises for one "eyebrow" Tenant  identification sign and one additional
Tenant  identification  sign on the  monument  sign  adjacent  to the  Building.
Tenant's rights to such signage shall be subject to all applicable  governmental
approvals.  Tenant  agrees  to  have  Landlord  install  and  maintain  Tenant's
identification  sign  in  such  designated  location  in  accordance  with  this
Paragraph 34 at Tenant's  sole cost and expense.  Tenant has no right to install
Tenant  identification  signs in any other location in, on or about the Premises
or the  Development  and will not display or erect any other signs,  displays or
other  advertising  materials that are visible from the exterior of the Building
or from within the Building in any interior or exterior common areas.  The size,
design,  color and other physical aspects of any and all permitted  sign(s) will
be subject to (i)  Landlord's  written  approval  prior to  installation,  which
approval  may  be  withheld  in  Landlord's  discretion,   (ii)  any  covenants,
conditions or  restrictions  governing the  Premises,  and (iii) any  applicable
municipal  or  governmental  permits  and  approvals.   Tenant  will  be  solely
responsible for all costs for installation,  maintenance,  repair and removal of
any Tenant  identification  sign(s).  If Tenant fails to remove Tenant's sign(s)
upon  termination  of this Lease and repair any damage  caused by such  removal,
Landlord may do so at Tenant's sole cost and expense. Tenant agrees to reimburse
Landlord  for all  costs  incurred  by  Landlord  to  effect  any  installation,
maintenance  or  removal  on  Tenant's  account,  which  amount  will be  deemed
additional  rent,  and may  include,  without  limitation,  all sums  disbursed,
incurred or  deposited  by Landlord  including  Landlord's  costs,  expenses and
actual  attorneys' fees with interest thereon at the Interest Rate from the date
of Landlord's demand until paid by Tenant. At no cost to Tenant,  Landlord shall
appropriately  include  the name of Tenant and its  principal  employees  on the
Building directory. Any maintenance costs of Building Directory shall constitute
an  Operating  Expense.  Any sign rights  granted to Tenant under this Lease are
personal to Tenant and may not be assigned, transferred or otherwise conveyed to
any assignee or subtenant of Tenant without  Landlord's  prior written  consent,
which consent Landlord may withhold in its sole and absolute discretion.

35. LIMITATION ON LIABILITY.  Notwithstanding anything to the contrary contained
in this Lease, in consideration of the benefits  accruing  hereunder,  Tenant on
behalf of itself and all successors  and assigns of Tenant  covenants and agrees
that, in the event of any actual or alleged failure, breach or default hereunder
by Landlord: (a) Tenant's recourse against Landlord for monetary damages will be
limited to Landlord's  interest in the Building,  subject to the prior rights of
any Mortgagee,  including,  Landlord's interest in the rents of the Building and
any insurance  proceeds  payable to Landlord;  (b) except as may be necessary to
secure  jurisdiction  of the  partnership  or  company,  no partner or member of
Landlord  shall be sued or named as a party in any suit or action and no service
of process  shall be made  against  any  partner or member of  Landlord;  (c) no
partner or member of Landlord shall be required to answer or otherwise  plead to
any service of process;  (d) no  judgment  will be taken  against any partner or
member of  Landlord  and any  judgment  taken  against  any partner or member of
Landlord may be vacated and set aside at any time after the fact; (e) no writ of
execution  will be  levied  against  the  assets  of any  partner  or  member of
Landlord;  (f) the  obligations  under  this  Lease do not  constitute  personal
obligations  of  the  individual  members,  partners,   directors,  officers  or
shareholders  of  Landlord,  and  Tenant  shall not seek  recourse  against  the
individual members, partners, directors, officers or shareholders of Landlord or
any of their  personal  assets for  satisfaction  of any liability in respect to
this Lease;  and (g) these  covenants and  agreements  are  enforceable  both by
Landlord and also by any partner or member of Landlord.

36. FINANCIAL  STATEMENTS.  Prior to the execution of this Lease by Landlord and
at any time  during  the Term of this  Lease  upon ten (10) days  prior  written
notice from Landlord, Tenant agrees to provide Landlord with a current financial
statement for Tenant and any  guarantors of Tenant and financial  statements for
the two (2) years prior to the current  financial  statement year for Tenant and
any guarantors of Tenant.  Such statements are to be prepared in accordance with
generally accepted accounting  principles and, if such is the normal practice of
Tenant, audited by an independent certified public accountant.

                                      -28-
 49

37.   QUIET ENJOYMENT.  Landlord covenants and agrees with Tenant that upon
Tenant paying the rent required under this Lease and paying all other charges
and performing all of the covenants and provisions on Tenant's part to be
observed and performed under this Lease, Tenant may peaceably and quietly
have, hold and enjoy the Premises in accordance with this Lease without
hindrance or molestation by Landlord or its employees or agents.

38.   MISCELLANEOUS.

(a)  Conflict of Laws.  This Lease shall be  governed  by and  construed  solely
pursuant to the laws of the State of California, without giving effect to choice
of law principles thereunder.

(b) Successors and Assigns.  Except as otherwise  provided in this Lease, all of
the covenants, conditions and provisions of this Lease shall be binding upon and
shall  inure to the benefit of the parties  hereto and their  respective  heirs,
personal  representatives,  successors and assigns.

(c) Professional  Fees and Costs. If either Landlord or Tenant should bring suit
against  the other with  respect  to this  Lease,  then all costs and  expenses,
including  without  limitation,  actual  professional  fees  and  costs  such as
appraisers',  accountants' and attorneys' fees and costs,  incurred by the party
which  prevails  in such  action,  whether  by  final  judgment  or out of court
settlement,  shall be paid by the other party,  which  obligation on the part of
the other party shall be deemed to have accrued on the date of the  commencement
of such action and shall be enforceable  whether or not the action is prosecuted
to judgment.  As used herein,  attorneys' fees and costs shall include,  without
limitation,  attorneys' fees, costs and expenses incurred in connection with any
(i) postjudgment motions; (ii) contempt  proceedings;  (iii) garnishment,  levy,
and debtor and third  party  examination;  (iv)  discovery;  and (v)  bankruptcy
litigation.

(d) Terms and Headings.  The words  "Landlord" and "Tenant" as used herein shall
include  the plural as well as the  singular.  Words used in any gender  include
other genders. The paragraph headings of this Lease are not a part of this Lease
and shall have no effect upon the  construction  or  interpretation  of any part
hereof.

(e) Time.  Time is of the  essence  with  respect  to the  performance  of every
provision of this Lease in which time of performance is a factor.

(f) Prior Agreement;  Amendments.  This Lease constitutes and is intended by the
parties  to be a  final,  complete  and  exclusive  statement  of  their  entire
agreement  with  respect  to the  subject  matter  of  this  Lease.  This  Lease
supersedes any and all prior and  contemporaneous  agreements and understandings
of any kind  relating  to the subject  matter of this Lease.  There are no other
agreements, understandings,  representations,  warranties, or statements, either
oral or in  written  form,  concerning  the  subject  matter of this  Lease.  No
alteration,  modification,  amendment or  interpretation  of this Lease shall be
binding on the parties  unless  contained  in a writing  which is signed by both
parties.

(g)  Separability.  The  provisions of this Lease shall be considered  separable
such that if any  provision  or part of this  Lease is ever held to be  invalid,
void or illegal under any law or ruling, all remaining  provisions of this Lease
shall remain in full force and effect to the maximum extent permitted by law.

(h) Recording.  Neither  Landlord nor Tenant shall record this Lease nor a short
form memorandum thereof without the consent of the other.

(i) Counterparts.  This Lease may be executed in one or more counterparts,  each
of which shall constitute an original and all of which shall be one and the same
agreement.

(j) Nondisclosure of Lease Terms.  Tenant acknowledges and agrees that the terms
of this  Lease  are  confidential  and  constitute  proprietary  information  of
Landlord. Disclosure of the terms could adversely affect the ability of Landlord
to negotiate other leases and impair Landlord's relationship with other tenants.
Accordingly,  Tenant  agrees  that it, and its  partners,  officers,  directors,
employees,  agents  and  attorneys,  shall  not  intentionally  and  voluntarily
disclose  the terms  and  conditions  of this  Lease to any  newspaper  or other

39.   EXECUTION OF LEASE.

(a) Joint and Several  Obligations.  If more than one person executes this Lease

agreement that (i) each of them is jointly and severally liable for the keeping,
observing and performing of all of the terms, covenants, conditions,  provisions
and agreements of this Lease to be kept,  observed and performed by Tenant,  and
(ii) the term  "Tenant"  as used in this Lease means and  includes  each of them

signature of any one or more of them, with respect to the tenancy of this Lease,
including, but not limited to, any renewal, extension,  expiration,  termination
or modification of this Lease,  will be binding upon each and all of the persons
executing this Lease as Tenant with the same force and effect as if each and all
of them had so acted or so given or received such notice or refund or so signed.

(b) Tenant as Corporation  or  Partnership.  If Tenant  executes this Lease as a
corporation or partnership,  then Tenant and the persons executing this Lease on
behalf of Tenant represent and warrant that such entity is duly qualified and in

adopted resolution of the board of directors of Tenant, a copy of which is to be
delivered to Landlord on  execution  hereof,  if  requested by Landlord,  and in
accordance  with the by-laws of Tenant,  and, in the case of a  partnership,  in

hereof, if requested by Landlord,  and that this Lease is binding upon Tenant in
accordance with its terms.

(c)  Examination of Lease.  Submission of this  instrument by Landlord to Tenant
for  examination  or signature by Tenant does not constitute a reservation of or
option  for  lease,  and it is not  effective  as a  lease  or  otherwise  until

                                    ADDENDUM

This LEASE ADDENDUM  ("Addendum") is attached to,  incorporated  into and amends
and supplements that certain Office Building Lease (the "Lease") entered into as
of the _____ day of  December,  1999,  by and between  Kilroy  Realty,  L.P.,  a
Delaware  limited  partnership  ("Landlord"),  and The  Ryland  Group,  Inc.,  a
Maryland corporation ("Tenant").  Landlord and Tenant agree that notwithstanding
anything  contained in the Lease to the  contrary,  the Lease as modified by the
provisions set forth in this Addendum  represents the full negotiated  agreement
of the parties,  and the provisions of this Addendum will be deemed to be a part
of the Lease and will  supersede  any contrary or  conflicting  provision in the
Lease and prevail and control for all purposes. This Addendum, together with the
Lease  itself,  and all other  Exhibits,  Riders and  Addenda  attached  thereto
represents  the fully  integrated  and binding  agreement  of the  parties.  All
references  in the Lease and in this  Addendum to "Lease" are to be construed to
mean the Lease as amended and  supplemented by this Addendum.  All terms used in
this  Addendum,  unless  specifically  defined in this  Addendum,  have the same
meaning as such terms have in the Lease.

1.    BUILDING.  Prior to the Commencement Date, Landlord shall cause the
Building to be constructed pursuant to the specifications attached as
Schedule "1" to the Work Letter Agreement attached hereto as Exhibit "C".

2.    RIGHT OF FIRST OFFER TO LEASE ADDITIONAL SPACE.

(a) Exercise of Right. Provided Tenant is not in default under this Lease at the
time Tenant  attempts to exercise  Tenant's  right of First Offer,  Tenant shall
have a  continuing  right of first  offer  to  lease  ("Tenant's  Right of First
Offer"), any space in the first (1st) or second (2nd) floors of the Building, to
the extent  such space is  available,  or becomes  available  for lease to third
parties  after the  expiration  of any existing  lease for such space during the
Lease Term,  including the expiration of all renewal or extension  options,  and
after the existing tenant or occupant  vacates such space ("First Offer Space").
Tenant's  Right of First Offer is subject and  subordinate  to the rights of all
other  existing  tenants of the  Building  with prior  expansion or lease rights
relative to any such First Offer Space.

(b) Tenant Request.  Promptly  following  written request ("Tenant  Request") by
Tenant  (which may not be given more than twice in any twelve  (12)  consecutive
month period),  Landlord will give Tenant written notice of the  availability of
any First Offer Space and the date the existing  tenant or occupant,  if any, is
expected to vacate such space ("Landlord's  Availability  Notice").  Within five
(5) days following delivery of Landlord's  Availability Notice, Tenant will have
the right to request from Landlord in writing a written  statement setting forth
the  basic  economic   terms,   including,   but  not  limited  to,   Landlord's
determination of the Monthly Base Rent, tenant  improvement  allowance,  if any,
and all  other  economic  terms  and  conditions  (collectively,  the  "Economic
Terms"),  upon which  Landlord is willing to lease the First Offer Space desired
by  Tenant,  either to Tenant or to a third  party.  Such  Economic  Terms  will
represent Landlord's reasonable determination of the fair market rental rate for
such First Offer Space. Such fair market rental rate will mean the annual amount
per rentable square foot,  projected during the relevant period, that a willing,
comparable,  non-equity tenant (excluding sublease and assignment  transactions)
would pay, and a willing,  comparable landlord of a comparable Class "A" quality
office  building  located in the Calabasas  area would  accept,  at arm's length
(what  Landlord is  accepting  in current  transactions  for the Building may be
considered),  for space of  comparable  size,  quality  and floor  height as the
leased  area at issue  taking into  account  the age,  quality and layout of the
existing  improvements in the leased area at issue and taking into account items
that professional real estate brokers customarily consider,  including,  but not
limited to,  rental  rates,  office  space  availability,  tenant  size,  tenant
improvement allowances,  operating expenses and allowance, parking charges, free
rent,  reduced  rent,  free  parking,  reduced  parking,  and  any  other  lease
concessions, if any, then being charged or granted by Landlord or the lessors of
such similar office buildings.

(c)  Within ten (10)  business  days after  receipt of the  Economic  Terms from
Landlord,  Tenant must give  Landlord  written  notice  pursuant to which Tenant
shall elect to either: (i) lease such First Offer Space upon such Economic Terms
and the same  non-Economic  Terms as set forth in the Lease with  respect to the
Premises;  (ii) refuse to lease such First  Offer  Space,  specifying  that such
refusal is not based upon the Economic Terms, but upon Tenant's lack of need for
such First Offer Space, in which event Landlord may at any time thereafter lease
such First Offer Space to any party upon any terms Landlord  deems  appropriate;
or (iii) refuse to lease the First Offer Space,  specifying that such refusal is
based upon the Economic  Terms,  in which event Tenant will also specify revised
Economic  Terms upon which  Tenant is  willing to lease such First  Offer  Space
(provided that Tenant may not specify a different lease term for the First Offer
Space). Tenant's failure to timely choose either clause 2(c)(i), clause 2(c)(ii)
or  clause  2(c)(iii)  above  will be  deemed  to be  Tenant's  choice of clause
2(c)(ii) above.

                                    ADDENDUM
                                      -1-
 52

(d) If Tenant gives Landlord notice pursuant to clause 2(c)(iii) above, Landlord
may elect,  within five (5) days  following  receipt of such notice from Tenant,
either to: (i) lease such First Offer Space to Tenant upon such revised Economic
Terms proposed by Tenant,  and the same other non-Economic Terms as set forth in
this Lease;  or (ii) lease the First Offer Space at any time  thereafter  to any
third party upon terms which are not substantially  more favorable to said party
than the Economic Terms originally  proposed by Landlord.  Landlord's failure to
timely choose either clause  2(d)(i) or clause  2(d)(ii) above will be deemed to
be Landlord's choice of clause 2(d)(ii) above.

(e) If Tenant chooses (or is deemed to have chosen) clause 2(c)(ii) above, or if
Landlord  chooses (or is deemed to have chosen) clause 2(d)(ii) above,  Tenant's
Right to Lease any First  Offer  Space will be null and void until  Tenant  once
again  validly  delivers  to  Landlord a Tenant  Request,  in which  event,  the
procedures and sequences set forth above will be followed.  If Tenant  exercises
its  Right  of  First  Offer as  provided  herein,  the  parties  will  promptly
thereafter execute an amendment to the Lease to include the First Offer Space in
the Premises and to document the lease terms thereof.

3. BENEFICIAL  OCCUPANCY.  Notwithstanding the provisions of the Lease regarding
the payment of Monthly Base Rent,  Landlord hereby agrees that Tenant shall have
the  beneficial  use of the Premises  with a fifty  percent  (50%)  abatement of
Monthly  Base  Rent for a period  of one  hundred  twenty  (120)  days  from the
Commencement Date (the "Beneficial Occupancy Period"); provided, however, in the
event that Tenant  defaults  under the terms of the Lease at any time during the
Term of the Lease, and such default remains uncured  following the expiration of
any applicable  curative  periods under the Lease,  all such abated Monthly Base
Rent for the  Beneficial  Occupancy  Period  shall  become  immediately  due and
payable by Tenant to Landlord.

IN WITNESS WHEREOF, the parties hereto have executed this Addendum as of the day
and year of execution of the Lease.

TENANT:                                     LANDLORD:

the  area  covered  by  the  elevator  lobbies,  corridors,  special  stairways,
restrooms,  mechanical  rooms,  electrical  rooms and telephone  closets on such
floors,  or (ii) for multiple  tenancy floors,  a pro-rata portion of all of the

      Tenant  agrees to meet with Tenant's  architect  and/or space planner (the
      "Tenant's  Architect") for the purpose of promptly  preparing  preliminary
      space plans for the layout of Premises  ("Space  Plans").  The Space Plans
      are to be  sufficient to convey the  architectural  design of the Premises
      and layout of the Tenant  Improvements  therein and are to be submitted to
      Landlord in accordance with the Work Schedule for Landlord's approval.  If
      Landlord  reasonably  disapproves any aspect of the Space Plans,  Landlord
      will advise Tenant in writing of such disapproval and the reasons therefor
      in accordance with the Work Schedule.  Tenant will then submit to Landlord
      for Landlord's approval,  in accordance with the Work Schedule, a redesign
      of the Space Plans  incorporating  the  revisions  reasonably  required by
      Landlord.

      and in accordance with the Work Schedule,  Tenant's Architect will prepare
      and complete architectural plans, drawings and specifications and complete
      engineered mechanical,  structural and electrical working drawings for all
      of the Tenant  Improvements  for the  Premises  (collectively,  the "Final

      partitions  and  walls),  layout,  lighting,  finish and  decoration  work
      (including carpeting and other floor coverings) for the Premises;  (b) all
      internal and external  communications  and utility  facilities  which will
      require conduiting or other improvements from the Base Building shell work
      and/or  within  common  areas;  and (c) all other  specifications  for the
      Tenant  Improvements.  The Final Plans will be  submitted  to Landlord for
      signature to confirm  that they are  consistent  with the Space Plans.  If
      Landlord reasonably disapproves any aspect of the Final Plans based on any
      inconsistency  with the Space Plans,  Landlord  agrees to advise Tenant in
      writing of such disapproval and the reasons therefor within the time frame
      set forth in the Work  Schedule.  In  accordance  with the Work  Schedule,
      Tenant will then cause  Tenant's  Architect  to  redesign  the Final Plans
      incorporating the revisions reasonably requested by Landlord so as to make
      the Final Plans consistent with the Space Plans.

           (c)  Requirements of Tenant's Final Plans.  Tenant's Final Plans will
      include locations and complete dimensions, and the Tenant Improvements, as
      shown on the Final Plans,  will: (i) be compatible  with the Base Building
      and with the design,  construction and equipment of the Building;  (ii) if
      not comprised of the Landlord's Building standards set forth those certain
      Outline  Specifications  for Calabasas  Park Centre dated January 29, 1999
      (the  "Standards"),  then compatible with and of at least equal quality as
      the Standards and approved by Landlord;  (iii) comply with all  applicable
      laws,  ordinances,  rules and regulations of all governmental  authorities
      having jurisdiction,  and all applicable insurance  regulations;  (iv) not
      require  Building  service  beyond the level  normally  provided  to other
      tenants in the Building and will not overload the Building floors; and (v)
      be of a nature and  quality  consistent  with the  overall  objectives  of
      Landlord for the Building, as determined by Landlord in its reasonable but
      subjective discretion.

           (d)  Submittal of Final Plans.  Once approved by Landlord and Tenant,
      Tenant's  Architect  will  submit  the  Final  Plans  to  the  appropriate
      governmental  agencies  for plan  checking  and the issuance of a building
      permit.  Tenant's  architect,  with  Tenant's  cooperation,  will make any
      changes  to  the  Final  Plans  which  are  requested  by  the  applicable
      governmental  authorities to obtain the building permit. After approval of
      the Final Plans no further  changes may be made without the prior  written
      approval of both  Landlord  and Tenant.  Tenant shall pay any excess costs
      resulting from the design and/or construction of such changes.

           (e) Changes to Shell of Building. If the Final Plans or any amendment
      thereof or supplement  thereto shall require changes in the Base Building,
      the  increased  cost of the Base Building work caused by such changes will
      be paid for by Tenant or charged  against  the  "Allowance"  described  in
      Paragraph 5 below.

           (f) Work Cost Estimate and Statement.  Prior to the  commencement  of
      construction of any of the Tenant  Improvements  shown on the Final Plans,
      Tenant will submit to Landlord a written  estimate of the cost to complete
      the Tenant  Improvement  Work, which written estimate will be based on the
      Final Plans taking into account any modifications which may be required to
      reflect changes in the Final Plans required by the City or County in which
      the  Premises  are  located  and  based on the  lowest  bid  submitted  by
      reputable tenant improvement contractors selected by Tenant and reasonably
      approved by Landlord (the "Work Cost  Estimate").  Submission and approval
      of the  Work  Cost  Estimate  will  proceed  in  accordance  with the Work
      Schedule.  Upon  Landlord's  approval  of the  Work  Cost  Estimate  (such
      approved  Work Cost  Estimate  to be  hereinafter  known as the "Work Cost
      Statement"),  Tenant  will have the  right to  purchase  materials  and to
      commence the construction of the items included in the Work Cost Statement
      pursuant to Paragraph 6 hereof.  If the total costs  reflected in the Work
      Cost Statement exceed the Allowance described in Paragraph 5 below, Tenant
      agrees to pay such  excess to Tenant's  Contractor  (defined  below).  The
      contractor selected by Landlord and Tenant through the competitive bidding
      process is referred to herein as "Tenant's  Contractor".  Tenant's written
      construction  agreement  with  Tenant's  Contractor  shall be  subject  to
      Landlord's prior review and approval.

           (b) Excess Costs.  The cost of each item referenced in Paragraph 5(a)
      above shall be charged against the Allowance. If the Work Cost exceeds the
      Allowance, Tenant agrees to timely pay to Tenant's Contractor such excess.
      In no event  will the  Allowance  be used to pay for  Tenant's  furniture,
      artifacts,  equipment,  telephone  systems or any other  item of  personal
      property which is not affixed to the Premises.

           (c)  Changes.  If,  after the Final Plans have been  prepared and the
      Work Cost Statement has been  established,  Tenant requires any changes or
      substitutions  to the Final Plans,  any additional  costs related  thereto
      including  fees  for  Tenant's  Contractor  are to be  paid by  Tenant  to
      Tenant's  Contractor  prior to the  commencement  of  construction  of the
      changed or substituted Tenant Improvements. Any changes to the Final Plans
      will be subject to the review and  approval of Landlord  and Tenant in the
      manner set forth in Paragraph 4 above and will, if necessary,  require the
      Work Cost  Statement  to be revised and agreed upon  between  Landlord and
      Tenant in the manner set forth in subparagraph  4(f) above.  Landlord will
      have the right to decline Tenant's request for a change to the Final Plans
      if such changes are inconsistent with the provisions of Paragraph 4 above,
      or if the  change  would  unreasonably  delay  construction  of the Tenant
      Improvements  and the  Commencement  Date of the  Lease.  Landlord  hereby
      agrees to respond to Tenant's  request for changes or substitutions to the
      Final Plans  within five (5)  business  days of Tenant's  written  request
      therefor.

           (d)  Governmental  Cost  Increases.  If  increases in the cost of the
      Tenant  Improvements  as set forth in the Work Cost  Statement  are due to
      requirements of any governmental  agency,  Tenant agrees to pay the amount
      of such increase; provided, however, that Landlord will first apply toward
      any such increase any remaining balance of the Allowance.

           (e) Unused  Allowance  Amounts.  Any unused  portion of the Allowance
      upon completion of the Tenant  Improvements will not be refunded to Tenant
      or be available to Tenant as a credit  against any  obligations  of Tenant
      under the Lease  unless  Tenant has paid for excess  costs as described in
      subparagraphs  5(b), 5(c) or 5(d), in which case the unused  Allowance may
      be applied toward such excess cost amounts and paid to Tenant.

           (f) Additional  Payment By Landlord.  In addition to the  "Allowance"
      Landlord shall  reimburse  Tenant for reasonable  out-of-pocket  costs and
      expenses incurred by Tenant directly in connection with the preparation of
      the Space Plans, including but not limited to, any preliminary space plans
      for the  Premises  Tenant may have  caused to be  professionally  prepared
      prior to execution of the Lease; provided, however, Tenant must deliver to
      Landlord  written  evidence  of such costs and  expenses no later than the
      Commencement  Date and provided further that, in no event shall Landlord's
      obligation to reimburse  Tenant exceed Ten One Hundredths  Dollars ($0.10)
      per Usable Square Foot of the Premises.

      6.  CONSTRUCTION  OF  TENANT  IMPROVEMENTS.  In  accordance  with the Work
Schedule,  Tenant's  Contractor  will commence and  diligently  proceed with the
construction of the Tenant Improvements,  subject to Tenant Delays (as described
in  Paragraph 9 below) and Force  Majeure  Delays (as  described in Paragraph 10
below).  Tenant shall cause Tenant's  Contractor to coordinate at all times with
Landlord's  Contractor  with  respect to the  completion  of the Base  Building.
Tenant or Tenant's Contractor's failure to do so shall constitute a Tenant Delay
for purposes of Paragraph 9 hereinbelow.

      7.  DELIVERY OF MATERIALS TO THE PREMISES;  UTILITIES.  Tenant shall cause
Tenant's Contractor to deliver construction materials to the Premises located on
the fourth (4th) floor through the Building  windows which shall be "popped out"

first  (1st)  floor shall be  delivered  through the back door of the  Building.
Tenant hereby  acknowledges  that Tenant shall be required to provide  temporary
restroom  facilities,  and temporary  power for the  construction  of the Tenant
Improvements, at Tenant's sole cost and expense.

      8.   COMMENCEMENT DATE AND SUBSTANTIAL COMPLETION

           (a)  Commencement  Date.  The Term of the Lease will  commence on the
      date (the "Commencement  Date") which is the earlier of: (i) July 1, 2000;
      (ii) the date Tenant moves into the Premises to commence  operation of its
      business  in all or any  portion  of the  Premises;  or (iii) the date the
      Tenant  Improvements  have  been  "substantially  completed"  (as  defined
      below). If substantial completion of the Tenant Improvements is delayed as
      a result of  Landlord's  failure to deliver the  Premises on or before the
      date set forth in the Work  Schedule  (other  than by reason of any Tenant
      Delays),  then the Commencement Date as otherwise  established pursuant to
      subparagraph  8(a)(i)  will  be  extended  by the  number  of days of such
      delays.  Notwithstanding the foregoing, the Commencement Date shall not be
      deemed to have occurred  until all parking areas to be made  available for
      Tenant's use as of the  Commencement  Date,  have been  completed  and all
      landscaping  required  for the  issuance  of a  temporary  Certificate  of
      Occupancy  or  equivalent  approval  from the local  government  authority
      permitting Tenant's occupancy of the Premises shall have been completed.

           (b) Substantial Completion;  Punch-List. For purposes of subparagraph
      8(a) above, the Tenant  Improvements  will be deemed to be  "substantially
      completed" when Tenant's  Contractor  certifies in writing to Landlord and
      Tenant  that : (a)  Tenant  has  reasonable  access to the  Premises;  (b)
      Tenant's  Contractor  has  substantially   performed  all  of  the  Tenant
      Improvement Work required to be performed by Tenant under this Work Letter
      Agreement,  other than  decoration and minor  "punch-list"  type items and
      adjustments  which do not materially  interfere with Tenant's access to or
      use of the Premises; and (c) a temporary certificate of occupancy or other
      required  equivalent  approval  from  the  local  governmental   authority
      permitting   occupancy  of  the   Premises   has  been  issued.   Tenant's
      construction  contract with  Tenant's  Contractor  shall require  Tenant's
      Contractor  to timely issue the foregoing  certification.  Within ten (10)
      days after receipt of such certificate from Tenant's Contractor,  Landlord
      and Tenant will conduct a  walk-through  inspection  of the Premises  with
      Tenant's   Contractor  and  provide  to  Tenant's   Contractor  a  written
      punch-list  specifying  those  decoration and other punch-list items which
      require  completion,  which  items  Tenant's  Contractor  will  thereafter
      diligently complete.

           (c) Delivery of Possession.  Landlord agrees to deliver possession of
      the  Premises to Tenant to permit  Tenant's  Contractor  to  commence  the
      construction  of the  Tenant  Improvements  in  accordance  with  the Work
      Schedule  attached hereto as "Schedule 2", subject to Force Majeure Delays
      (not to exceed one hundred  eighty (180) days) and any Tenant  Delays.  On
      the date that the Premises shall be delivered to Tenant's Contractor,  the
      Building shall be closed in and secured.

      9. TENANT  DELAYS.  For  purposes of this Work Letter  Agreement,  "Tenant
Delays" means any delay in the completion of the Tenant  Improvements  resulting
from  any or all of the  following:  (a)  Tenant's  failure  or the  failure  of
Tenant's  Architect  or  Tenant's  Contractor  to  timely  perform  any of their
respective  obligations  pursuant to this Work Letter  Agreement,  including any
failure to complete,  on or before the due date therefor,  any action item which
is Tenant's  responsibility  pursuant to the Work Schedule delivered by Landlord
to Tenant pursuant to this Work Letter Agreement;  (b) Tenant's changes to Space
Plans or Final Plans after Landlord's approval thereof; (c) Tenant's request for
materials,  finishes,  or installations which are not readily available or which
are incompatible  with the Standards;  (d) any delay of Tenant in making payment
to Landlord for Tenant's share of the Work Cost; or (e) any other act or failure
to act by Tenant,  Tenant's  employees,  agents,  Tenant's  Architect,  Tenant's
Contractor,  independent  contractors,   consultants  and/or  any  other  person
performing or required to perform services on behalf of Tenant.

      10. FORCE MAJEURE DELAYS. For purposes of this Work Letter, "Force Majeure
Delays" means any actual delay in the  construction of the Tenant  Improvements,
which is beyond the  reasonable  control of Landlord or Tenant,  as the case may
be, as described in Paragraph 33 of the Lease.

           (a)  Compliance  With  Paragraph  13.  Tenant  shall  comply with the
      applicable  provisions  of Paragraph 13 of the Lease which do not conflict
      with this Work Letter Agreement, as if the Tenant Improvement Work were an
      "Alteration"  under  Paragraph 13 of the Lease,  including but not limited
      to, contractor's insurance requirements and lien-free work requirements.

           (b) Good and  Workmanlike  Construction.  Tenant  shall  use its best

      breach of warranty, personal injury or property damage).

           (e) Defects.  Landlord  shall have no  responsibility  for the Tenant
      Improvement Work and Tenant will remedy,  at Tenant's own expense,  and be
      responsible for any and all defects in the Tenant Improvement Work whether
      the same shall affect the Tenant  Improvement  Work in  particular  or any
      parts of the Building in general.

           (f) No  Interference.  All of Tenant's  contractors,  subcontractors,
      employees,  servants  and agents  must work in harmony  with and shall not
      interfere with any labor employed by Landlord,  or Landlord's  contractors
      with respect to any portion of the Building.

Lease,  Landlord shall disburse the Allowance (or the unexpended  portion of the
Allowance as of the date of this  Amendment),  to Tenant to reimburse Tenant for
the actual Tenant  Improvement  Work Cost which Tenant incurs in connection with
the construction of the Tenant Improvements in accordance with the following:

           Code Sections 3143 and 3171);

rental,  supplies,   equipment  and  related  operating  expenses,  and  (iv)  a

of the Building and an administrative  fee for the management of the Development
Common Area  determined as a percentage  of  Development  Common Area  Operating
Expenses;

(i)   supplies, materials, equipment and tools including rental of personal

replacement of any Building equipment needed to operate the Building at the same

over such reasonable  period as Landlord shall determine,  on a consistent basis
and in  accordance  with  multi-story  office  building  industry  standards  of
competing  first-class  office  buildings,  with a return on capital at the then

                                  EXHIBIT "E"

accounts  and  accounting  practices  consistently  maintained  by Landlord on a
year-to-year  basis in  compliance  with such  provisions  of this  Lease as may
affect such accounts (the "Accounting Practices"). Operating Expenses applicable
to Common Areas  servicing the Building and other  buildings in the  Development
shall be  allocated  to the  Building  on a  straight  pro-rata  basis  with the
Building  bearing its share in the proportion  that the Rentable  Square Foot of
the Building bears to the total Rentable Square Footage of all buildings sharing
such Common Areas.

charge,  improvement  bond, tax or similar  imposition  imposed by any authority
having the direct power to tax,  including  any city,  county,  state or federal
government, or any school, agricultural, lighting, drainage or other improvement
or  special  assessment  district  thereof,  as against  any legal or  equitable
interest of Landlord in the Premises,  Building, Common Areas or the Development
(as such terms are defined in the Lease), adjusted to reflect an assumption that
the  Building is fully  assessed  for real  property tax purposes as a completed
building ready for occupancy, including the following by way of illustration but
not limitation:

(a)   any tax on Landlord's "right" to rent or "right" to other income from
the Premises or as against Landlord's business of leasing the Premises;

(b) any  assessment,  tax,  fee,  levy or charge in  substitution,  partially or
totally, of any assessment,  tax, fee, levy or charge previously included within
the  definition  of real  property  tax,  it being  acknowledged  by Tenant  and
Landlord  that  Proposition  13 was  adopted  by the  voters  of  the  State  of
California in the June, 1978 election and that assessments,  taxes, fees, levies
and charges may be imposed by  governmental  agencies for such  services as fire
protection, street, sidewalk and road maintenance,  refuse removal and for other
governmental  services  formerly  provided  without charge to property owners or
occupants.  It is the  intention  of Tenant and  Landlord  that all such new and
increased  assessments,  taxes,  fees, levies and charges be included within the
definition of "real property taxes" for the purposes of this Lease;

(c) any  assessment,  tax, fee,  levy or charge  allocable to or measured by the
area of the  Premises or other  premises in the  Building or the rent payable by
Tenant  hereunder  or  other  tenants  of  the  Building,   including,   without
limitation,  any gross  receipts  tax or  excise  tax  levied by state,  city or
federal government,  or any political  subdivision thereof,  with respect to the
receipt  of such  rent,  or upon or with  respect  to the  possession,  leasing,
operation,  management,  maintenance,  alteration,  repair,  use or occupancy by
Tenant of the  Premises,  or any  portion  thereof but not on  Landlord's  other
operations;

(d) any  assessment,  tax,  fee,  levy or charge  upon this  transaction  or any
document to which Tenant is a party,  creating or transferring an interest or an
estate in the Premises; and/or

                                  EXHIBIT "E"
                                      -2-
 71

(e) any assessment,  tax, fee, levy or charge by any governmental agency related
to any  transportation  plan, fund or system  (including  assessment  districts)
instituted within the geographic area of which the Building is a part.

Notwithstanding  the foregoing,  if at any time after the Commencement Date, the
amount of Real Property Taxes and  Assessments  decreases,  then for purposes of
all subsequent  Lease Years,  including the Lease Year in which such decrease in
Real Property Taxes and Assessments occurs, Tenant's Operating Expense Allowance
shall be decreased by an amount equal to such  decrease in Real  Property  Taxes
and Assessments.  Further,  notwithstanding the foregoing, in the event Landlord
obtains  earthquake  insurance  coverage  following  the Base  Year  causing  an
increase to Operating  Expenses,  then the Operating  Expenses for the Base Year
shall be deemed to have been increased by the amount of the applicable  premiums
attributable to such coverage.

Conversely,  in the event that the amount of Operating Expenses decreases due to
Landlord's subsequent election to eliminate earthquake coverage, or in the event
of a  reduction  in the  cost of  providing  utilities,  security  and/or  other
services to the Building and/or  Development for any reason,  Operating Expenses
for Base Year shall be deemed to have been  decreased by the amount equal to any
such decrease.

3.    Items Excluded From Operating Expenses.  Notwithstanding the provisions
of Paragraphs 1 and 2 above to the contrary, "Operating Expenses" will  not
include:

(a)   Landlord's federal or state income, franchise, inheritance or estate
taxes;

(b)   any ground lease rental;

(c) costs  incurred by Landlord  for the repair of damage to the Building to the
extent that Landlord is reimbursed by insurance  (and for this purpose  Landlord
shall not be deemed to have been reimbursed with respect to any deductible),  or
condemnation proceeds or by tenants, warrantors or other third persons;

(d)  depreciation,  amortization and interest  payments,  except as specifically
provided  herein,  and except on  materials,  tools,  supplies  and  vendor-type
equipment  purchased by Landlord to enable Landlord to supply services  Landlord
might  otherwise  contract  for with a third  party,  where  such  depreciation,
amortization  and interest  payments  would  otherwise have been included in the
charge for such third party's services, all as determined in accordance with the
Accounting Practices;

(e) brokerage commissions,  finders' fees, attorneys' fees, space planning costs

                      STANDARDS FOR UTILITIES AND SERVICES

The  following  standards  for  utilities  and services are in effect.  Landlord
reserves  the  right  to adopt  nondiscriminatory  modifications  and  additions
hereto.

Subject to the terms and conditions of the Lease and provided  Tenant remains in
occupancy of the Premises, Landlord will provide or make available the following
utilities and services:

1.    Provide non-attended automatic elevator facilities Monday through
Friday, except holidays, from 8 a.m. to 6 p.m., and have one elevator
available for Tenant's use at all other times.

2. On Monday  through  Friday,  except  holidays,  from 8 a.m. to 6 p.m.  and on
Saturday  from 8 a.m.  to 12 Noon (and other times for a  reasonable  additional
charge  to be fixed  by  Landlord),  ventilate  the  Premises  and  furnish  air
conditioning or heating on such days and hours, when in the reasonable  judgment
of Landlord it may be required for the  comfortable  occupancy of the  Premises.
The air  conditioning  system achieves maximum cooling when the window coverings
are  extended  to the full length of the window  opening  and  adjusted to a 45o
angle upwards.  Landlord will not be responsible for room temperatures if Tenant
does not keep all window  coverings in the Premises  extended to the full length
of the window opening and adjusted to a 45o angle upwards whenever the system is
in operation.  Tenant agrees to cooperate fully at all times with Landlord,  and
to abide by all  reasonable  regulations  and  requirements  which  Landlord may
prescribe  for the  proper  function  and  protection  of said air  conditioning
system. Tenant agrees not to connect any apparatus,  device,  conduit or pipe to
the chilled and hot water air conditioning supply lines of the Building.  Tenant
further  agrees  that  neither  Tenant  nor  its  servants,  employees,  agents,
visitors,  licensees  or  contractors  shall at any time  enter  the  mechanical
installations or facilities of the Building or the Development or adjust, tamper
with, touch or otherwise in any manner affect said  installations or facilities.
The cost of  maintenance  and  service  calls to  adjust  and  regulate  the air
conditioning  system will be charged to Tenant if the need for maintenance  work
results from either Tenant's  adjustment of room thermostats or Tenant's failure
to comply with its  obligations  under this Exhibit,  including  keeping  window
coverings  extended to the full length of the window  opening and  adjusted to a
45o  angle  upwards.  Such  work  will be  charged  at  hourly  rates  equal  to
then-current  journeyman's  wages for air  conditioning  mechanics.  During  the
Original Term, Landlord shall provide "after-hours" HVAC service to the Premises
at a cost equal to Thirty-Five Dollars ($35.00) per hour, per floor,  subject to
adjustment  based on actual  increases  or decreases  in  Landlord's  applicable
rates.

3. Landlord will make available to the Premises,  24 hours per day, seven days a
week,  electric current as required by the Building standard office lighting and
fractional  horsepower  office business  machines  including  copiers,  personal
computers  and word  processing  equipment  in an amount not to exceed  four (4)
watts per  square  foot per  normal  business  day.  Tenant  agrees,  should its
electrical  installation or electrical consumption be in excess of the aforesaid
quantity or extend beyond normal business hours, to reimburse  Landlord  monthly
for the measured  consumption  at the average cost per kilowatt  hour charged to
the Building during the period. If a separate meter is not installed at Tenant's
cost,  such  excess  cost will be  established  by an  estimate  agreed  upon by
Landlord  and  Tenant,  and if the  parties  fail to  agree,  such  cost will be
established  by an  independent  licensed  engineer  selected  by  Landlord  and
approved by Tenant (such approval not to be unreasonably  withheld,  conditioned
or delayed), , whose fee shall be shared equally by Landlord and Tenant.  Tenant
agrees not to use any apparatus or device in, upon or about the Premises  (other
than standard office business  machines,  personal computers and word processing
equipment)  which may in any way  increase the amount of such  services  usually
furnished or supplied to said Premises, and Tenant further agrees not to connect
any apparatus or device with wires,  conduits or pipes,  or other means by which
such  services  are  supplied,  for the purpose of using  additional  or unusual
amounts of such services without the written consent of Landlord.  Should Tenant
use the same to excess,  the refusal on the part of Tenant to pay upon demand of
Landlord  the  amount  established  by  Landlord  for such  excess  charge  will
constitute  a breach of the  obligation  to pay rent  under  this Lease and will
entitle Landlord to the rights therein granted for such breach.  Tenant's use of
electric  current will never exceed the capacity of the feeders to the Building,
or the risers or wiring  installation  and  Tenants  will not  install or use or
permit the  installation  or use of any computer or electronic  data  processing
equipment in the Premises  (except standard office business  machines,  personal
computers and word  processing  equipment)  without the prior written consent of
Landlord.

4. Water will be available  in public  areas for drinking and lavatory  purposes
only, but if Tenant requires, uses or consumes water for any purpose in addition
to ordinary drinking and lavatory  purposes,  Landlord may install a water meter
and thereby measure Tenant's water  consumption for all purposes.  Tenant agrees
to pay  Landlord  for the cost of the  meter  and the  cost of the  installation
thereof and throughout the duration of Tenant's  occupancy Tenant will keep said
meter and  installation  equipment in good working  order and repair at Tenant's
own cost and  expense,  in  default of which  Landlord  may cause such meter and
equipment  to be replaced or repaired  and collect the cost thereof from Tenant.
Tenant  agrees to pay for water  consumed,  as shown on such meter,  as and when
bills are rendered, and on default in making such payment, Landlord may pay such
charges and collect the same from Tenant.  Any such costs or expenses  incurred,
or  payments  made by Landlord  for any of the  reasons or purposes  hereinabove
stated will be deemed to be additional rent payable by Tenant and collectible by
Landlord as such.

5. Landlord will provide cleaning and janitorial services to the Premises Monday
through Friday in accordance with the specifications attached hereto as Schedule
1.

6.  Landlord  reserves  the right to stop  service  of the  elevator,  plumbing,
ventilation,  air conditioning and electrical systems, when necessary, by reason
of accident or emergency or for repairs,  alterations or  improvements,  when in
the  judgment of Landlord  such  actions are  desirable or necessary to be made,
until said  repairs,  alterations  or  improvements  shall have been  completed.
Landlord shall use commercially  reasonable  efforts to minimize  disruptions to
Tenant's use of the Premises,  subject to the limitations hereinafter set forth.
Landlord will have no responsibility or liability for failure to supply elevator
facilities,  plumbing,  ventilating,  air conditioning or electric service, when
prevented from so doing by strike or accident or by any cause beyond  Landlord's
reasonable  control,  or  by  laws,  rules,  orders,   ordinances,   directions,
regulations or by reason of the  requirements of any federal,  state,  county or
municipal  authority  or failure of gas,  oil or other  suitable  fuel supply or
inability  by  exercise of  reasonable  diligence  to obtain  gas,  oil or other
suitable fuel supply.  It is expressly  understood and agreed that any covenants
on  Landlord's  part to  furnish  any  services  pursuant  to any of the  terms,
covenants, conditions, provisions or agreements of this Lease, or to perform any
act or thing for the benefit of Tenant,  will not be deemed breached if Landlord
is unable to furnish or perform the same by virtue of a strike or labor  trouble
or any other cause whatsoever beyond Landlord's control.

                              RULES AND REGULATIONS

A.    General Rules and Regulations.  The following rules and regulations
govern the use of the Building and the Development Common Areas.  Tenant will
be bound by such rules and regulations and agrees to cause Tenant's
Authorized Users, its employees, subtenants, assignees, contractors,
suppliers, customers and invitees to observe the same.

1.  Except  as  specifically  provided  in the  Lease to which  these  Rules and
Regulations are attached,  no sign,  placard,  picture,  advertisement,  name or
notice may be installed or displayed on any part of the outside or inside of the
Building or the  Development  without  the prior  written  consent of  Landlord.
Landlord will have the right to remove,  at Tenant's expense and without notice,
any sign installed or displayed in violation of this rule. All approved signs or
lettering on doors and walls are to be printed, painted, affixed or inscribed at
the expense of Tenant and under the direction of Landlord by a person or company
designated or approved by Landlord.

2. If Landlord objects in writing to any curtains,  blinds,  shades,  screens or
hanging plants or other similar  objects  attached to or used in connection with
any  window  or door of the  Premises,  or placed  on any  windowsill,  which is
visible from the exterior of the Premises,  Tenant will immediately  discontinue
such use. Tenant agrees not to place anything  against or near glass  partitions
or doors or  windows  which may  appear  unsightly  from  outside  the  Premises
including from within any interior common areas.

3. Tenant will not obstruct any sidewalks,  halls, passages,  exits,  entrances,
elevators,  escalators,  or stairways of the Development.  The halls,  passages,
exits,  entrances,  elevators and stairways are not open to the general  public,
but are open, subject to reasonable regulations,  to Tenant's business invitees.
Landlord  will in all cases  retain  the right to  control  and  prevent  access
thereto of all persons  whose  presence in the  reasonable  judgment of Landlord
would be  prejudicial to the safety,  character,  reputation and interest of the
Development  and its tenants,  provided that nothing  herein  contained  will be
construed to prevent such access to persons with whom any tenant  normally deals
in the  ordinary  course of its  business,  unless  such  persons are engaged in
illegal or  unlawful  activities.  No tenant and no  employee  or invitee of any
tenant will go upon the roof of the Building.

4. Landlord  expressly reserves the right to absolutely  prohibit  solicitation,
canvassing,  distribution of handbills or any other written material,  peddling,
sales  and  displays  of  products,  goods  and  wares  in all  portions  of the
Development  except as may be  expressly  permitted  under the  Lease.  Landlord
reserves  the right to restrict  and regulate the use of the common areas of the
Development and Building by invitees of tenants providing services to tenants on
a periodic or daily basis including food and beverage vendors. Such restrictions
may  include  limitations  on time,  place,  manner and  duration of access to a
tenant's  premises for such purposes.  Without limiting the foregoing,  Landlord
may require  that such parties use service  elevators,  halls,  passageways  and
stairways for such  purposes to preserve  access within the Building for tenants
and the general public.

5.  Landlord  reserves  the right to  require  tenants to  periodically  provide
Landlord with a written list of any and all business invitees which periodically
or  regularly  provide  goods and  services  to such  tenants  at the  premises.
Landlord  reserves the right to preclude all vendors from entering or conducting
business  within the Building and the Development if such vendors are not listed
on a tenant's list of requested vendors.

6. Landlord reserves the right to exclude from the Building between the hours of
6 p.m.  and 8 a.m.  the  following  business  day, or such other hours as may be
established  from time to time by Landlord,  and on Sundays and legal  holidays,
any person  unless  that  person is known to the person or employee in charge of
the Building or has a pass or is properly identified. Tenant will be responsible
for all persons for whom it requests  passes and will be liable to Landlord  for
all acts of such persons.  Landlord will not be liable for damages for any error
with regard to the  admission to or  exclusion  from the Building of any person.
Landlord  reserves  the  right to  prevent  access  to the  Building  in case of
invasion,  mob, riot,  public excitement or other commotion by closing the doors
or by other appropriate action.

7. The directory of the Building or the Development will be provided exclusively
for the display of the name and location of tenants  only and Landlord  reserves
the right to exclude any other names therefrom.

8. All cleaning and  janitorial  services for the  Development  and the Premises
will be  provided  exclusively  through  Landlord,  and except  with the written
consent of Landlord,  no person or persons other than those approved by Landlord
will be employed by Tenant or permitted to enter the Development for the purpose
of  cleaning  the  same.   Tenant  will  not  cause  any  unnecessary  labor  by
carelessness or indifference to the good order and cleanliness of the Premises.

door  lock in the  Premises.  Landlord  may  make a  reasonable  charge  for any
additional keys.  Tenant shall not make or have made additional keys, and Tenant
shall not alter any lock or install any new additional  lock or bolt on any door
of the Premises.  Tenant,  upon the termination of its tenancy,  will deliver to
Landlord the keys to all doors which have been  furnished to Tenant,  and in the
event of loss of any keys so furnished, will pay Landlord therefor.

10. If Tenant requires telegraphic, telephonic, burglar alarm, satellite dishes,
antennae or similar  services,  it will first obtain  Landlord's  approval,  and
comply with,  Landlord's  reasonable rules and  requirements  applicable to such
services, which may include separate licensing by, Landlord.

merchandise or other property will be received in the Building or carried in the
elevators  except  between such hours and in such elevators as may be designated
by Landlord.  Tenant's initial move in and subsequent deliveries of bulky items,
such as furniture,  safes and similar  items will,  unless  otherwise  agreed in
writing by  Landlord,  be made  during the hours of 6:00 p.m. to 6:00 a.m. or on
Saturday or Sunday.  Deliveries  during  normal office hours shall be limited to
normal office  supplies and other small items.  No deliveries will be made which
impede or interfere with other tenants or the operation of the Building.

12.  Tenant will not place a load upon any floor of the Premises  which  exceeds
the load per square  foot which  such floor was  designed  to carry and which is
allowed by law. Landlord will have the right to reasonably prescribe the weight,
size and position of all safes, heavy equipment, files, materials,  furniture or
other  property  brought into the  Building.  Heavy  objects will, if considered
necessary by Landlord,  stand on such  platforms as determined by Landlord to be
necessary to properly distribute the weight, which platforms will be provided at
Tenant's  expense.  Business  machines  and  mechanical  equipment  belonging to
Tenant,  which cause noise or vibration that may be transmitted to the structure
of the Building or to any space therein to such a degree as to be  objectionable
to any tenants in the Building or Landlord,  are to be placed and  maintained by
Tenant,  at  Tenant's  expense,  on  vibration   eliminators  or  other  devises
sufficient to eliminate  noise or vibration.  Tenant will be responsible for all
structural  engineering  required to determine  structural  load, as well as the
expense  thereof.  The persons  employed to move such equipment in or out of the
Building  must be  reasonably  acceptable  to  Landlord.  Landlord  will  not be
responsible for loss of, or damage to, any such equipment or other property from
any cause,  and all damage done to the  Building by  maintaining  or moving such
equipment or other property will be repaired at the expense of Tenant.

left in vehicles.  In any event,  the total  liability  of Landlord,  if any, is
limited to Two Hundred  Fifty  Dollars  ($250.00) for all damages or loss to any
car. Landlord is not responsible for loss of use.

             Amendment and Restatement Effective as of March 1, 1998

                                    RECITALS

Director  Deferred  Compensation  Plan (the  "Plan"),  is  adopted by The Ryland
Group,  Inc.  (the  "Employer"),  effective  as of  March 1,  1998.  The Plan is
maintained for the benefit of certain of the Employer's  executive employees and
Directors.  When  originally  adopted on March 1, 1997, the Plan  constituted an
amendment  and  restatement  of each of the following  plans,  all of which were
merged into this Plan:  The Ryland Group,  Inc.  Deferred  Compensation  Savings
Plan; The Ryland Group,  Inc. Salary  Deferral Plan; and The Ryland Group,  Inc.
Unfunded Deferred Director Fee Plan.

      The purpose of the Plan is to offer  participants  an opportunity to elect
to defer the receipt of compensation in order to provide  deferred  compensation
benefits  taxable  pursuant to section 451 of the Internal Revenue Code of 1986,
as amended (the "Code"), and to provide a deferred compensation vehicle to which
the Employer may credit certain amounts on behalf of  participants.  The Plan is
intended to be a "top-hat" plan under sections  201(2),  301(a)(3) and 401(a)(1)
of the Employee Retirement Income Security Act of 1974 ("ERISA").

      The purpose of this Amendment and Restatement of the Plan is to reflect in
the Plan  certain  amendments  to the Plan  adopted  since the  Plan's  original
effective date.

      Accordingly,  the  following  Amendment  and  Restatement  of the  Plan is
adopted.

           employee benefit plan(s) of the Employer,  of beneficial ownership of
           twenty  percent  (20%) or more of the  combined  voting  power of the
           Employer's then outstanding voting securities;

      (ii) the first purchase under a tender offer or exchange offer, other than
           an offer by the  Employer  or any  employee  benefit  plan(s)  of the

           have been purchased;

      (iii)during any period of two (2) consecutive  years,  individuals who, at

           Employer  cease for any  reason  to  constitute  at least a  majority
           thereof,  unless the election or the  nomination  for the election by
           stockholders  of the  Employer of each new Director was approved by a
           vote of at least  two-thirds  (2/3rds) of the Directors then still in
           office who were Directors at the beginning of the period; or

      (iv) approval by stockholders of the Employer of a merger,  consolidation,

      3.2  PARTICIPANT   COMPENSATION   DEFERRALS.   In  accordance  with  rules
established by the Employer, a Participant may elect to defer Compensation which
is not yet payable and which would otherwise be paid to the Participant. Amounts
so  deferred  will  be  considered  a  Participant's  "Compensation  Deferrals".
Ordinarily,  a Participant  shall make such an election with respect to a coming
twelve (12) month Plan Year during the period  beginning  on the  December 1 and
ending on the  December 31 of the prior Plan Year,  or during such other  period
established by the Employer.

           Compensation  Deferrals  shall be made  through  regular  payroll  or
retainer/meeting fee deductions and/or through an election by the Participant to
defer a bonus payment not yet payable to him or her at the time of the election.
The Participant may reduce his or her regular  payroll or  retainer/meeting  fee
deduction  Compensation  Deferral  amount  for a  particular  year as of, and by
written notice delivered to the Employer at least thirty (30) days prior to, the
beginning  of any  regular  payroll  period,  with such  reduction  being  first
effective for  Compensation to be earned in that payroll period.  In the case of
bonus payment  deferrals,  the  Participant  may reduce his or her bonus payment
deferral  percentage  for a particular  year by giving notice to the Employer of
the reduced bonus  payment  Compensation  Deferral  amount prior to the date the
applicable bonus is first due to be paid.

           Once   made,   a   Compensation    Deferral    regular   payroll   or
retainer/meeting  fee deduction  election shall continue in force  indefinitely,
until  reduced  by  the  Participant  as  aforesaid  or  until  changed  by  the
Participant  for a  coming  year  on a  subsequent  Participant  Enrollment  and
Election Form provided by the Employer. A bonus payment reduction election, or a
reduction  thereof  pursuant to the foregoing,  shall continue in force only for
the Plan Year for which the election is first effective.

           Compensation Deferrals shall be deducted by the Employer from the pay
of a deferring  Participant.  There shall be  established  and maintained by the
Employer  a  separate   Compensation  Deferral  Account  in  the  name  of  each
Participant  to which shall be credited  or  debited:  (a) amounts  equal to the
Participant's  Compensation Deferrals;  (b) amounts equal to any deemed earnings
or losses (to the extent  realized,  based upon deemed fair market  value of the
Account's  deemed assets)  attributable or allocable  thereto;  and (c) expenses
and/or taxes charged to that Account.

           A Participant  shall at all times be 100% vested in amounts  credited
to his or her Participant Compensation Deferral Account.

      3.3  CONTRIBUTIONS  TO THE  TRUST.  Amounts  shall be  contributed  by the
Employer  to the  Trust  maintained  under  Section  11.1  equal to the  amounts
required to be credited to the Participant's Account under Sections 3.1 and 3.2.
The Employer  shall make a good faith effort to contribute  these amounts to the
Trust as soon as is  practicable  after such  amounts are  determined.  Employer
contributions to the Trust shall be made in cash, Stock Unit Plan credits, or in
common stock of the Employer.

                               ALLOCATION OF FUNDS
                               -------------------

      4.1  ALLOCATION  OF DEEMED  EARNINGS  OR LOSSES ON  ACCOUNTS.  Subject  to
Section 4.5, each Participant  shall have the right to direct the Employer as to
how amounts in his or her Plan Account  shall be deemed to be invested.  Subject
to such  limitations as may from time to time be required by law, imposed by the
Employer or the Trustee or contained  elsewhere in the Plan, and subject to such
operating  rules  and  procedures  as may be  imposed  from  time to time by the
Employer,  prior to the date on which a  direction  will become  effective,  the
Participant shall have the right to direct the Employer as to how amounts in his
or her Account shall be deemed to be invested.

           The  Employer   shall  direct  the  Trustee  to  invest  the  account
maintained  in the Trust on behalf of the  Participant  pursuant  to the  deemed
investment  directions the Employer  properly has received from the Participant.
The  value of the  Participant's  Account  shall  be  equal to the  value of the
account  maintained  under the Trust on  behalf of the  Participant.  As of each
valuation  date of the Trust,  the  Participant's  Account  will be  credited or
debited to reflect the Participant's deemed investments of the Trust.

           The  Participant's  Plan Account will be credited or debited with the
increase or decrease in the realizable net asset value or credited interest,  as
applicable,  of the  designated  deemed  investments,  as  follows.  As of  each
Valuation  Date,  an amount equal to the net increase or decrease in  realizable
net asset  value or credited  interest,  as  applicable  (as  determined  by the
Employer or the Trustee, as applicable), of each deemed investment option within
the Account  since the  preceding  Valuation  Date shall be allocated  among all
Participants'  Accounts  deemed  to be  invested  in that  investment  option in
accordance  with the ratio which the portion of the Account of each  Participant
which is deemed to be invested  within that  investment  option,  determined  as
provided  herein,  bears to the  aggregate of all amounts  deemed to be invested
within that investment option.

      4.2  ACCOUNTING  FOR  DISTRIBUTIONS.  As of the  date of any  distribution
hereunder,  the  distribution  made  hereunder to the  Participant or his or her
Beneficiary or  Beneficiaries  shall be charged to such  Participant's  Account.
Such amounts shall be charged on a pro rata basis against the investments of the
Trust in which the Participant's Account is deemed to be invested.

      4.3  SEPARATE  ACCOUNTS.  A  separate  account  under  the  Plan  shall be
established and maintained hereunder to reflect the Account for each Participant
with  sub-accounts to show separately the applicable  deemed  investments of the
Account.

                                       7

 99

      4.4 INTERIM VALUATIONS. If it is determined by the Employer that the value
of a Participant's  Account as of any date on which distributions are to be made
differs  materially  from the value of the  Participant's  Account  on the prior
Valuation Date upon which the distribution is to be based, the Employer,  in its
discretion,  shall  have the right to  designate  any date in the  interim  as a
Valuation  Date for the purpose of revaluing the  Participant's  Account so that
the Account will, prior to the distribution,  reflect its share of such material
difference in value.

      4.5  DEEMED  INVESTMENT  DIRECTIONS  OF  PARTICIPANTS.   Subject  to  such
limitations as may from time to time be required by law, imposed by the Employer
or the Trustee or contained elsewhere in the Plan, and subject to such operating
rules and procedures as may be imposed from time to time by the Employer,  prior
to and effective for each Designation  Date, each Participant may communicate to
the Employer a direction as to how his or her Plan Accounts  should be deemed to
be invested among such categories of deemed investments as may be made available
by the Employer hereunder. Such direction shall designate the percentage (in any
whole percent multiples) of the Participant's Plan Account which is requested to
be  deemed  to  be  invested   in  such   categories   of  deemed   investments.
Notwithstanding any contrary provision of the Plan,  Participants shall not have
the right to direct the deemed investment of deferrals of director retainer fees
that otherwise would have been payable in common stock of the Employer.  Rather,
deferrals of director  retainer fees that  otherwise  would have been payable in
common  stock of the  Employer  shall at all times be deemed to be  invested  in
common stock of the Employer.

           An election  concerning  deemed  investment  choices  shall  continue
indefinitely  until  changed by the  Participant  in a manner  specified  by the
Employer.  If the  Employer  receives  an initial or revised  deemed  investment
direction   which  it  deems  to  be  incomplete,   unclear  or  improper,   the
Participant's investment direction then in effect shall remain in effect (or, in
the  case  of a  deficiency  in an  initial  deemed  investment  direction,  the
Participant shall be deemed to have filed no deemed investment  direction) until
the next  Designation  Date,  unless the Employer  provides for, and permits the
application of, corrective action prior thereto.

           If the Employer possesses (or is deemed to possess as provided above)
at any  time  directions  as to the  deemed  investment  of less  than  all of a
Participant's Account, the Participant shall be deemed to have directed that the
undesignated  portion of the Account be deemed to be invested in a money market,
fixed  income,  stable  value or similar fund made  available  under the Plan as
determined by the Employer in its discretion.

           Each   Participant   hereunder,   as  a  condition   to  his  or  her
participation hereunder,  agrees to indemnify and hold harmless the Employer and
its agents and  representatives  from any losses or damages of any kind relating
to the deemed investment of the Participant's Account hereunder.

           Each  reference in this Section to a  Participant  shall be deemed to
include, where applicable, a reference to a Beneficiary.

      4.6  EXPENSES.   Expenses,   including  Trustee  fees,  allocable  to  the
administration  or  operation of an Account  maintained  under the Plan shall be
paid by the Employer  unless,  in the  discretion of the Employer,  the Employer
elects to charge such expenses, or any portion thereof,  against the appropriate
Participant's  Account or Participants'  Accounts. If an expense, or any portion
thereof,  is charged against a Participant's  Account,  at the discretion of the
Employer,  such  expense,  or  portion  thereof,  either  (i)  will  reduce  the
contribution  to the Trust under Section 3.3 next due to be made by the Employer
in respect of the  Account,  or (ii) will be paid from the Trust to the Employer
out of assets of the Trust corresponding to the Participant's Account hereunder.

      4.7 TAXES. Any taxes generated by earnings in an Account, as determined by
the Employer,  shall be paid by the Employer  unless,  in the  discretion of the
Employer,  the  Employer  elects to charge such taxes  against  the  appropriate
Participant's  Account  or  Participants'  Accounts.  If a tax amount is charged
against a Participant's Account, at the discretion of the Employer, such expense
either (i) will reduce the  contribution to the Trust under Section 3.3 next due
to be made by the Employer in respect of the Account,  or (ii) will be paid from
the  Trust to the  Employer  out of assets  of the  Trust  corresponding  to the
Participant's Account.

                             ENTITLEMENT TO BENEFITS
                             -----------------------

      5.1  FIXED  PAYMENT  DATES;  TERMINATION  OF  EMPLOYMENT.  On  his  or her
Participant  Enrollment  and  Election  Form, a  Participant  may select a fixed
payment  date for the  payment or  commencement  of payment of his or her vested
Account, which will be valued and payable according to the provisions of Article
6. Such payment  dates may be extended to later dates so long as elections to so
extend are made by the Participant prior to the then applicable fixed date. Such
payment dates may not be accelerated.

           Alternatively,  on his or her  Participant  Enrollment  and  Election
Form, a Participant  may select payment or commencement of payment of his or her
vested Account at his or her  termination of employment or Director  status with
the  Employer,  or at  the  earlier  of a  fixed  payment  date  or  his  or her
termination  of  employment or Director  status with the Employer.  In either of
these cases,  the extension and  non-acceleration  rules  discussed  above shall
apply to such fixed  payment date and/or  termination  of  employment  date,  as
applicable.

           Any fixed  payment date elected by a  Participant  as provided  above
must be no  earlier  than the  January 1 of the third  calendar  year  after the
calendar year in which the election is made. If a Participant  does not select a
payment  date  or  dates  as  aforesaid,  his or her  vested  account  shall  be
distributed  or  commence  to be  distributed,  as provided in Article 6, at the
termination of his or her employment or Director status with the Employer.

      5.2  HARDSHIP  DISTRIBUTIONS.  In the event of  financial  hardship of the
Participant,  as hereinafter  defined, the Participant may apply to the Employer
for the  distribution  of all or any  part  of his or her  vested  Account.  The
Employer  shall  consider  the  circumstances  of each such  case,  and the best
interests of the Participant and his or her family, and shall have the right, in
its  sole  discretion,  if  applicable,  to  allow  such  distribution,  or,  if
applicable,  to direct a  distribution  of part of the amount  requested,  or to
refuse to allow any  distribution.  Upon a finding of  financial  hardship,  the
Employer shall make the appropriate distribution to the Participant from amounts
held by the Employer in respect of the Participant's vested Account. In no event
shall the aggregate amount of the  distribution  exceed either the full value of
the Participant's  vested Account or the amount determined by the Employer to be
necessary to alleviate the  Participant's  financial  hardship (which  financial
hardship may be considered to include any taxes due because of the  distribution
occurring because of this Section),  and which is not reasonably  available from
other resources of the Participant.  For purposes of this Section,  the value of
the  Participant's  vested  Account  shall be  determined  as of the date of the
distribution.

                                       9

 101

           "Financial  hardship"  means (a) a severe  financial  hardship to the
Participant  resulting from a sudden and  unexpected  illness or accident of the
Participant  or of a  dependent  (as  defined  in Code  section  152(a))  of the
Participant,  (b) loss of the  Participant's  property due to  casualty,  or (c)
other similar extraordinary and unforeseeable  circumstances arising as a result
of events beyond the control of the Participant,  each as determined to exist by
the  Employer.  A  distribution  may be made  under this  Section  only with the
consent of the Employer.

      5.3 APPLICATION TO TRUSTEE. On the date or dates on which a Participant or
Beneficiary  is  entitled to payment  under  Section  5.1,  the  Participant  or
Beneficiary need not make  application for payment to the Employer,  but instead
may make  application  for  payment  directly  to the  Trustee who shall pay the
Participant  or  Beneficiary  the  appropriate  amount  directly  from the Trust
without the consent of the Employer. The Trustee shall report the amount of each
such payment, and any withholding thereon, to the Employer.

      5.4  RE-EMPLOYMENT  OF  RECIPIENT,   ETC..  If  a  Participant   receiving
installment distributions pursuant to Section 6.2 is re-employed by the Employer
(or  becomes a member  of the  Employer's  Board of  Directors),  the  remaining
distributions  due to the Participant  shall be suspended until such time as the
Participant (or his or her Beneficiary) once again becomes eligible for benefits
under  Section  5.1 or 5.2,  at which  time such  distribution  shall  commence,
subject to the limitations and conditions contained in this Plan.

                            DISTRIBUTION OF BENEFITS
                            ------------------------

      6.1  AMOUNT.  A  Participant  (or  his or her  Beneficiary)  shall  become
entitled to receive,  on or about the date or dates selected by the  Participant
on his or her Participant  Enrollment and Election Form or, if none, on or about
the date of the Participant's  termination of employment or Director status with
the  Employer  (or  earlier as  provided  in Article  5), a  distribution  in an
aggregate  amount equal to the  Participant's  vested  Account.  Any payment due
hereunder  from the Trust  which is not paid by the Trust for any reason will be
paid by the Employer from its general assets.

                                       10
 102

      6.2  METHOD OF PAYMENT.

           (a)  Cash Or In-Kind Payments.  Payments under the Plan shall be made
in cash or in-kind, as elected by the Participant,  as permitted by the Employer
and the Trustee in their sole and absolute  discretion and subject to applicable
restrictions  on  transfer  as  may  be  applicable  legally  or  contractually.
Notwithstanding  the  foregoing,  payments in respect of Stock Unit Plan credits
that are deemed to be invested in common stock of the Employer, that are held in
a  Participant's  Account,  will be paid in the form of  Employer  common  stock
(except as otherwise permitted by the Employer).

           (b)  Timing and Manner of Payment.  In the case of distributions to a
Participant or his or her  Beneficiary  by virtue of an entitlement  pursuant to
Sections 5.1, an aggregate amount equal to the Participant's vested Account will
be paid by the Trust or the Employer,  as provided in Section 6.1, in a lump sum
or in five (5) or ten (10) substantially equal annual installments (adjusted for
gains and losses), as selected by the Participant as provided in Article 5.

           If a Participant fails to designate properly the manner of payment of
the Participant's benefit under the Plan, such payment will be in a lump sum.

           If  the  whole  or  any  part  of a  payment  hereunder  is  to be in
installments, the total to be so paid shall continue to be deemed to be invested
pursuant to  Sections  4.1 and 4.5 under such  procedures  as the  Employer  may
establish,  in which  case any  deemed  income,  gain,  loss or  expense  or tax
allocable  thereto (as determined by the Trustee,  in its  discretion)  shall be
reflected in the installment  payments,  in such equitable manner as the Trustee
shall determine.

      6.3 DEATH BENEFITS.  If a Participant  dies before  terminating his or her
employment or Director  status with the Employer and before the  commencement of
payments to the  Participant  hereunder,  the entire value of the  Participant's
Account shall be paid, at the time(s) selected by the Participant  under Article
5 and in the manner provided in Section 6.2, to the person or persons designated
in accordance with Section 7.1.

           Upon the death of a Participant  after payments  hereunder have begun
but before he or she has  received  all  payments to which he or she is entitled
under the Plan,  the remaining  benefit  payments shall be paid to the person or
persons  designated in accordance  with Section 7.1, in the manner in which such
benefits were payable to the Participant.

      6.4  WITHHOLDING.  All  distributions  under  the Plan are  subject  to
any applicable tax withholding, as determined by the Employer in its discretion.

                                    ARTICLE 7

                         BENEFICIARIES; PARTICIPANT DATA
                         -------------------------------

      7.1 DESIGNATION OF  BENEFICIARIES.  Each Participant from time to time may
designate any person or persons (who may be named  contingently or successively)
to receive  such  benefits  as may be  payable  under the Plan upon or after the
Participant's  death,  and such  designation may be changed from time to time by
the Participant by filing a new  designation.  Each  designation will revoke all
prior designations by the same Participant, shall be in a form prescribed by the
Employer,  and will be  effective  only when filed in writing  with the Employer
during the Participant's lifetime.

                                       11

 103

           In the absence of a valid Beneficiary designation, or if, at the time
any  benefit  payment is due to a  Beneficiary,  there is no living  Beneficiary
validly  named by the  Participant,  the  Employer  shall  pay any such  benefit
payment to the  Participant's  spouse,  if then  living,  but  otherwise  to the
Participant's then living descendants, if any, per stirpes, but, if none, to the
Participant's  estate.  In  determining  the  existence  or  identity  of anyone
entitled  to  a  benefit  payment,  the  Employer  may  rely  conclusively  upon
information supplied by the Participant's personal  representative,  executor or
administrator.

           If a  question  arises  as to the  existence  or  identity  of anyone
entitled to receive a benefit payment as aforesaid,  or if a dispute arises with
respect to any such payment, then,  notwithstanding the foregoing, the Employer,
in its sole discretion,  may distribute such payment to the Participant's estate
without liability for any tax or other  consequences which might flow therefrom,
or may take such other action as the Employer deems to be appropriate.

      7.2  INFORMATION  TO  BE  FURNISHED  BY  PARTICIPANTS  AND  BENEFICIARIES;
INABILITY TO LOCATE PARTICIPANTS OR BENEFICIARIES. Any communication,  statement
or notice addressed to a Participant or to a Beneficiary at his or her last post
office  address  as shown on the  Employer's  records  shall be  binding  on the
Participant or Beneficiary  for all purposes of the Plan. The Employer shall not
be obliged to search for any Participant or Beneficiary  beyond the sending of a
registered  letter to such last known  address.  If the  Employer  notifies  any
Participant  or  Beneficiary  that he or she is entitled to an amount  under the
Plan and the  Participant or Beneficiary  fails to claim such amount or make his
or her location known to the Employer within three (3) years  thereafter,  then,
except as otherwise  required by law, if the location of one or more of the next
of kin of the  Participant  is known to the  Employer,  the  Employer may direct
distribution  of such amount to any one or more or all of such next of kin,  and
in such proportions as the Employer  determines.  If the location of none of the
foregoing persons can be determined, the Employer shall have the right to direct
that the amount  payable  shall be deemed to be a  forfeiture,  except  that the
dollar amount of the  forfeiture,  unadjusted  for deemed gains or losses in the
interim,  shall be paid by the Employer if a claim for the benefit  subsequently
is made by the  Participant  or the  Beneficiary  to whom it was  payable.  If a
benefit payable to an unlocated Participant or Beneficiary is subject to escheat
pursuant to applicable state law, the Employer shall not be liable to any person
for any payment made in accordance with such law.

      8.1 ADMINISTRATIVE  AUTHORITY.  Except as otherwise  specifically provided
herein,  the Employer,  acting through its Board of Directors or the designee or
designees thereof,  shall have the sole  responsibility for and the sole control
of the operation and  administration  of the Plan,  and shall have the power and
authority to take all action and to make all decisions and interpretations which
may be necessary or  appropriate  in order to  administer  and operate the Plan,

responsibility to:

 104

           (a)  Resolve  and determine  all disputes or questions  arising under
the Plan,  and to remedy any  ambiguities,  inconsistencies  or omissions in the
Plan.

           (b)  Adopt  such rules of procedure and regulations as in its opinion
may be necessary for the proper and efficient  administration of the Plan and as
are consistent with the Plan.

           (c)  Implement  the Plan in  accordance  with its terms and the rules
and regulations adopted as above.

           (d)  Make  determinations  with  respect  to the  eligibility  of any
Eligible  Individual as a Participant  and make  determinations  concerning  the
crediting of Plan Accounts.

           (e)  Appoint  any  persons  or  firms,  or  otherwise  act to  secure
specialized  advice  or  assistance,  as it  deems  necessary  or  desirable  in
connection with the  administration  and operation of the Plan, and the Employer
shall be entitled to rely conclusively upon, and shall be fully protected in any
action or  omission  taken by it in good  faith  reliance  upon,  the  advice or
opinion  of such  firms or  persons.  The  Employer  shall  have the  power  and
authority to delegate from time to time by written instrument all or any part of
its duties,  powers or  responsibilities  under the Plan,  both  ministerial and
discretionary,  as it deems appropriate,  to any person or committee, and in the
same manner to revoke any such delegation of duties, powers or responsibilities.
Any action of such person or committee in the exercise of such delegated duties,
powers or responsibilities shall have the same force and effect for all purposes
hereunder  as if such  action  had been  taken  by the  Employer.  Further,  the
Employer  may  authorize  one or more  persons to  execute  any  certificate  or
document on behalf of the  Employer,  in which event any person  notified by the
Employer of such authorization shall be entitled to accept and conclusively rely
upon any such  certificate or document  executed by such person as  representing
action by the Employer  until such  notified  person shall have been notified of
the revocation of such authority.

      8.2 UNIFORMITY OF DISCRETIONARY  ACTS.  Whenever in the  administration or
operation  of the Plan  discretionary  actions by the  Employer  are required or
permitted,  such actions  shall be  consistently  and  uniformly  applied to all
persons  similarly  situated,  and no such  action  shall be taken  which  shall
discriminate in favor of any particular person or group of persons.

      8.3 LITIGATION.  Except as may be otherwise required by law, in any action
or judicial  proceeding  affecting the Plan, no Participant or Beneficiary shall
be entitled to any notice or service of process,  and any final judgment entered
in such action shall be binding on all persons interested in, or claiming under,
the Plan.

      8.4  CLAIMS  PROCEDURE.  Any person  claiming a benefit  under the Plan (a
"Claimant") shall present the claim, in writing, to the Employer or the Trustee,
and the  Employer  or the  Trustee  shall  respond in  writing.  If the claim is
denied,  the written notice of denial shall state, in a manner  calculated to be
understood by the Claimant:

                                       13
 105

           (a)  The  specific  reason or reasons for the denial,  with  specific
references to the Plan provisions on which the denial is based;

           (b)  A   description  of  any  additional   material  or  information
necessary for the Claimant to perfect his or her claim and an explanation of why
such material or information is necessary; and

           (c)  An explanation of the Plan's claims review procedure.

           The written notice denying or granting the Claimant's  claim shall be
provided  to the  Claimant  within  ninety  (90) days  after the  Employer's  or
Trustee's  receipt  of  the  claim,  unless  special  circumstances  require  an
extension of time for  processing  the claim.  If such an extension is required,
written notice of the extension shall be furnished by the Employer or Trustee to
the  Claimant  within the  initial  ninety (90) day period and in no event shall
such an  extension  exceed a period  of  ninety  (90)  days  from the end of the
initial ninety (90) day period.  Any extension notice shall indicate the special
circumstances  requiring  the  extension  and the date on which the  Employer or
Trustee  expects to render a decision  on the  claim.  Any claim not  granted or
denied within the period noted above shall be deemed to have been denied.

           Any  Claimant  whose  claim is denied,  or deemed to have been denied
under the preceding  sentence (or such  Claimant's  authorized  representative),
may,  within  sixty  (60) days  after the  Claimant's  receipt  of notice of the
denial,  or after the date of the deemed denial,  request a review of the denial
by notice given, in writing, to the Employer or Trustee. Upon such a request for
review,  the  claim  shall  be  reviewed  by the  Employer  or  Trustee  (or its
designated  representative)  which may,  but shall not be required to, grant the
Claimant a  hearing.  In  connection  with the  review,  the  Claimant  may have
representation,  may  examine  pertinent  documents,  and may submit  issues and
comments in writing.

           The decision on review  normally shall be made within sixty (60) days
of the Employer's  receipt of the request for review. If an extension of time is
required  due to special  circumstances,  the  Claimant  shall be  notified,  in
writing,  by the  Employer  or Trustee,  and the time limit for the  decision on
review  shall be extended  to one hundred  twenty  (120) days.  The  decision on
review  shall be in  writing  and  shall  state,  in a manner  calculated  to be
understood  by the  Claimant,  the  specific  reasons for the decision and shall
include  references  to the relevant  Plan  provisions  on which the decision is
based.  The written decision on review shall be given to the Claimant within the
sixty (60) day (or, if applicable,  the one hundred twenty (120) day) time limit
discussed  above. If the decision on review is not  communicated to the Claimant
within the sixty (60) day (or, if applicable,  the one hundred twenty (120) day)
period  discussed  above,  the claim  shall be deemed to have been  denied  upon
review.  All  decisions on review shall be final and binding with respect to all
concerned parties.

                                    ARTICLE 9
                                    ---------

                                    AMENDMENT
                                    ---------

      9.1 RIGHT TO AMEND. The Employer, by written instrument executed by a duly
authorized  representative  of the  Employer,  shall have the right to amend the
Plan,  at any time and with respect to any  provisions  hereof,  and all parties
hereto or claiming  any  interest  hereunder  shall be bound by such  amendment;
provided,  however,  that no such  amendment  shall deprive a  Participant  or a
Beneficiary of a right accrued hereunder prior to the date of the amendment.

      9.2 AMENDMENTS TO ENSURE PROPER CHARACTERIZATION OF PLAN.  Notwithstanding
the  provisions  of Section  9.1, the Plan may be amended by the Employer at any
time,  retroactively  if required in the  opinion of the  Employer,  in order to
ensure that the Plan is characterized as "top-hat" plan as described under ERISA
sections  201(2),  301(a)(3),  and  401(a)(1),  and to  conform  the Plan to the
provisions and  requirements  of any  applicable  law  (including  ERISA and the
Code).  No such amendment  shall be considered  prejudicial to any interest of a
Participant or a Beneficiary hereunder.

                                   ARTICLE 10
                                   ----------

                                   TERMINATION
                                   -----------

      10.1 EMPLOYER'S RIGHT TO TERMINATE OR SUSPEND PLAN. The Employer  reserves
the right to terminate the Plan and/or its obligation to make further credits to
Plan Accounts.  The Employer also reserves the right to suspend the operation of
the Plan for a fixed or indeterminate period of time.

      10.2 AUTOMATIC TERMINATION OF PLAN. The Plan automatically shall terminate
upon the dissolution of the Employer,  or upon its merger into or  consolidation
with any other corporation or business organization if there is a failure by the
surviving  corporation or business  organization to adopt specifically and agree
to continue the Plan.

      10.3  SUSPENSION OF  DEFERRALS.  In the event of a suspension of the Plan,
the Employer  shall  continue all aspects of the Plan,  other than  Compensation
Deferrals  and  Employer  Contribution   Credits,   during  the  period  of  the
suspension,  in which event  payments  hereunder will continue to be made during
the period of the suspension in accordance with Articles 5 and 6.

                                       15
 107

      10.4 ALLOCATION AND DISTRIBUTION. This Section shall become operative on a
complete  termination  of the Plan.  The  provisions  of this Section also shall
become  operative  in  the  event  of a  partial  termination  of the  Plan,  as
determined  by the  Employer,  but only with respect to that portion of the Plan
attributable to the Participants to whom the partial  termination is applicable.
Upon the effective date of any such event,  notwithstanding any other provisions
of the Plan, no persons who were not theretofore  Participants shall be eligible
to  become  Participants,  the value of the  interest  of all  Participants  and
Beneficiaries  shall be determined and, after deduction of estimated expenses in
liquidating and, if applicable, paying Plan benefits, paid to them as soon as is
practicable after such termination.

      10.5 SUCCESSOR TO EMPLOYER. Any corporation or other business organization
which is a successor  to the  Employer by reason of a  consolidation,  merger or
purchase of substantially all of the assets of the Employer shall have the right
to become a party to the Plan by adopting the same by resolution of the entity's
board of directors or other  appropriate  governing body. If, within ninety (90)
days from the effective  date of such  consolidation,  merger or sale of assets,
such new entity  does not become a party  hereto,  as above  provided,  the Plan
automatically  shall be  terminated,  and the  provisions  of Section 10.4 shall
become operative.

                                   ARTICLE 11
                                   ----------

                                    THE TRUST
                                    ---------

      11.1  ESTABLISHMENT  OF TRUST. The Employer shall establish the Trust with
the Trustee  pursuant to such terms and conditions as are set forth in the Trust
agreement to be entered into between the Employer and the Trustee.  The Trust is
intended to be treated as a "grantor" trust under the Code and the establishment
of the Trust is not intended to cause the  Participant to realize current income
on amounts contributed thereto, and the Trust shall be so interpreted.

                                   ARTICLE 12
                                   ----------

                                  MISCELLANEOUS
                                  -------------

      12.1  LIMITATIONS ON LIABILITY OF EMPLOYER.  Neither the  establishment of
the Plan nor any modification thereof, nor the creation of any account under the
Plan,  nor the  payment of any  benefits  under the Plan shall be  construed  as
giving to any  Participant or other person any legal or equitable  right against
the Employer, or any officer or employer thereof except as provided by law or by
any Plan provision. The Employer does not in any way guarantee any Participant's
Account from loss or depreciation, whether caused by poor investment performance
of a deemed  investment or the inability to realize upon an investment due to an
insolvency  affecting an  investment  vehicle or any other  reason.  In no event
shall the Employer, or any successor, employee, officer, director or stockholder
of the  Employer,  be liable to any person on  account  of any claim  arising by
reason  of the  provisions  of the  Plan  or of any  instrument  or  instruments
implementing its provisions, or for the failure of any Participant,  Beneficiary
or other person to be entitled to any particular tax  consequences  with respect
to the Plan, or any credit or distribution hereunder.

                                       16

      12.2  CONSTRUCTION.  If any provision of the Plan is held to be illegal or
void, such illegality or invalidity shall not affect the remaining provisions of
the Plan,  but shall be fully  severable,  and the Plan shall be  construed  and
enforced as if said illegal or invalid provision had never been inserted herein.
For all  purposes of the Plan,  where the context  admits,  the  singular  shall
include the plural,  and the plural  shall  include  the  singular.  Headings of
Articles and Sections  herein are inserted only for convenience of reference and
are not to be considered in the  construction of the Plan. The laws of the State
of Maryland  shall  govern,  control and  determine all questions of law arising
with respect to the Plan and the  interpretation  and validity of its respective
provisions,  except  where  those laws are  preempted  by the laws of the United
States.  Participation under the Plan will not give any Participant the right to
be retained in the service of the Employer nor any right or claim to any benefit
under the Plan unless such right or claim has specifically accrued hereunder.

           The Plan is intended to be and at all times shall be interpreted  and
administered so as to qualify as a top-hat plan (as aforesaid), and no provision
of the Plan shall be  interpreted  so as to give any individual any right in any
assets of the  Employer  which  right is  greater  than the  rights of a general
unsecured creditor of the Employer.

      12.3  SPENDTHRIFT  PROVISION.  No amount  payable  to a  Participant  or a
Beneficiary  under the Plan will, except as otherwise  specifically  provided by
law,  be  subject  in  any  manner  to  anticipation,   alienation,  attachment,
garnishment,  sale,  transfer,  assignment  (either at law or in equity),  levy,
execution, pledge, encumbrance,  charge or any other legal or equitable process,
and any  attempt  to do so will be void;  nor will any  benefit be in any manner
liable for or subject to the debts, contracts, liabilities, engagements or torts
of the person entitled thereto.  Further, (i) the withholding of taxes from Plan
benefit  payments,  (ii) the recovery under the Plan of overpayments of benefits
previously  made to a  Participant  or  Beneficiary,  (iii) if  applicable,  the
transfer  of benefit  rights from the Plan to another  plan,  or (iv) the direct
deposit of benefit  payments  to an  account  in a banking  institution  (if not
actually part of an arrangement  constituting an assignment or alienation) shall
not be construed as an assignment or alienation.

           In  the  event  that  any  Participant's  or  Beneficiary's  benefits
hereunder  are  garnished  or  attached by order of any court,  the  Employer or
Trustee may bring an action or a  declaratory  judgment in a court of  competent
jurisdiction to determine the proper  recipient of the benefits to be paid under
the Plan.  During the pendency of said action,  any benefits that become payable
shall be held as credits to the  Participant's or  Beneficiary's  Account or, if
the Employer or Trustee prefers,  paid into the court as they become payable, to
be  distributed  by the court to the  recipient as the court deems proper at the
close of said action.

      IN WITNESS WHEREOF, the Employer has caused this Amendment and Restatement
of the Plan to be executed  and its seal to be affixed  hereto,  effective as of
the 1st day of March, 1998.
