year,  the amount of  Additional  Rent due from Tenant shall be  proportionately
adjusted based on that portion of the year that this Lease was in effect.

      (g)   Tenant  shall  have the right for a period of thirty  (30)  calendar
days after  receipt of the Final Annual  Statement of Operating  Costs to review
Landlord's  books and records with respect to actual annual  Operating Costs for
the period covered by the Final Annual Statement of Operating Costs. Such review
shall take place in Landlord's manager's office in the Building or at such other
place as designated  by Landlord.  Tenant shall give Landlord not less than five
(5) business days nor more than fifteen (15) business days written notice of the
date on which Tenant intends to conduct such review.  In the event Tenant either
fails to give written  notice or thereafter  fails to complete  such  inspection
within five (5)  business  days after the date for the  inspection  set forth in
Tenant's  written  notice,  then Tenant's right to review  Landlord's  books and
records  shall  terminate on such 5th  business  day and the Final  Statement of
Operating  Costs in question  shall be binding on both Landlord and Tenant.  The
results of such review  shall be for the benefit of  Landlord  and Tenant  only,
shall be maintained in confidence by Tenant,  and shall not be  disseminated  or
furnished  to any other  person  or  entity.  Tenant  may use  certified  public
accountants  familiar with office building  operating expense billing procedures
to aid  Tenant in  conducting  the audit,  but  Tenant may not use any  auditing
services or similar  consultants  that are paid on a contingent fee basis or are
owned by,  affiliated  with,  employed  by or  related  to any  office  building
landlords or office building management companies or services.

      If, as a result of Tenant's  review,  Tenant  claims  that any  particular
items were incorrectly included as an Operating Costs under this Lease or Tenant
claims any mathematical  errors exist in the Final Statement of Operating Costs,
Tenant may give written  notice to Landlord  within five (5) business days after
the date of review..  Said notice may only contest Landlord's Final Statement of
Operating Costs for the two (2) reasons  included in this  subparagraph  (g) and
said notice  shall  clearly  reflect the  reasons for the  disagreement  and the
amount claimed by Tenant as owed from  Landlord.  Tenant and Landlord shall then
meet in an effort to resolve the differences in their respective findings.

      If a  resolution  is not  reached  within  thirty  (30)  business  days of
Tenant's written notice, then Landlord shall designate an independent  certified
public  accountant to audit the actual annual Operating  Expenses for the period
in  question.  The  findings  of said  accountant  shall be  binding on both the
Landlord and Tenant.

                                        5

<PAGE>

      To the extent that the accountant's determination of Operating Expenses is
less than ninety percent (90%) of the amount  reflected on the Landlord's  final
statement,  then Landlord shall bear the cost of the audit.  Conversely,  to the
extent  that the  accountant's  determination  of the  amount  reflected  on the
Landlord's  final  statement is equal to or within ninety  percent (90%) of said
statement, then Tenant shall bear the cost of the audit.

      If as a  result  of  such  audit  it is  determined  that  the  amount  of
Additional  Rent due  from  Tenant  shall be less  than  that  shown  due on the
Landlord's  statement.  Landlord  shall make such  adjustments  as  necessary to
correct such  statement and Landlord shall refund to Tenant any over payments of
Additional Rent made by Tenant.

      (h)   Tenant's payments of Additional Rent shall not be deemed payments of
base rental as that term is construed  relative to  governmental  wage and price
controls or analogous  governmental  actions  affecting the amount of rent which
Landlord may charge Tenant for the Premises.

to be wholly  untenantable  or not usable or not  repairable  within one hundred
eighty (180) days in the  determination of Landlord's  architect or engineer) by
storm, fire, earthquake or other casualty, Landlord shall have the option to:

            (i)   Terminate  this Lease as of the date of the  occurrence of the
storm,  earthquake,  fire or other  casualty by giving  written notice to Tenant
within ninety (90) days from the date of such damage or destruction; or

            (ii)  Commence  the  process of  restoration  of the  Premises  to a
tenantable  condition  within  thirty  (60)  days  from the date of  receipt  by
Landlord of all of the insurance  proceeds  paid with respect to such  casualty,
and proceed with due  diligence to complete  said  restoration  of the Premises.
Provided,  however,  that  Landlord  shall not be  obligated  to expend for such
repair an amount in excess of the net insurance  proceeds actually received as a
result of such  damage and in no event  shall  Landlord be required to repair or
replace any alteration or improvement  made by or for the Tenant,  including but
not limited to Tenant's Work (as defined in the Work  Agreement),  nor any trade
fixtures,  furniture,  equipment or other property  belonging to the Tenant.  If
Landlord  chooses to restore the Premises,  Rent shall abate with respect to the
untenantable  portion of the Premises from the date of such  casualty  until the
date of substantial restoration thereof.

      If Landlord  shall not elect to terminate  this Lease,  the Landlord shall
complete such  restoration  with reasonable  diligence within one hundred eighty
(180) days of the date of receipt by Landlord of all of the  insurance  proceeds
paid with respect to such casualty, as described above subject to Tenant Delays.
During  such  period  of  repair,  if any  portion  of  the  Premises  shall  be
untenantable as a result of casualty and Tenant has elected to no longer use the
Premises, Base Rental and Additional Rent shall abate beginning with the date of
such casualty and ending on the date the Premises are rendered  tenantable by an
amount  bearing the same ratio to the total amount of Base Rental and Additional
Rent due under this Lease as the  untenantable  portion of the Premises bears to
the  entire  Premises.  Notwithstanding  such  abatement.  Tenant  shall  remain
obligated to perform and  discharge all of its  remaining  covenants  under this
Lease during the period of abatement.

      (b)   If such damage or  destruction  occurs  within,  one (1) year of the
expiration of the Term, either party may, at its option on written notice to the
other party within  thirty (30) days of such  destruction  or damage,  terminate
this Lease as of the date of such destruction or damage. Notwithstanding, Tenant
may elect to Terminate this lease if, based on Landlords determination, that the
Premises or Building are not  repairable  within 180 days from the date in which
Landlord notifies Tenant,  which date of notification  shall be not more than 90
days from the date of the damage/destruction,

      (c)   Rent shall not abate if the damage or  destruction  of the Premises,
whether  total or  partial,  is the  result of the  negligence  of  Tenant,  its
contractors, subcontractors, agents, employees, guests or invitees.

certain concessions granted by Landlord to Tenant.  Landlord, in addition to but
not in lieu of or in  limitation  of any  other  right  or  remedy  provided  to
Landlord under the terms of this Lease or otherwise (but only to the extent such
sum is not reimbursed to Landlord in conjunction  with any other payment made by
Tenant to Landlord), shall have the right to be immediately repaid by Tenant the

with preparing or improving the Premises to Tenant's  specifications and any and
all costs and expenses  incurred in  renovating or altering the Premises to make
it  suitable  for  reletting.   Notwithstanding   any  such  re-letting  without
termination.  Landlord may at any time thereafter  elect to terminate this Lease
for such previous breach; or

            (iii) Landlord, in addition to but not in lieu ofor in limitation of
any other right or remedy  provided to Landlord under the terms of this Lease or
otherwise  (but only to die extent  such sum is not  reimbursed  to  Landlord in
conjunction  with any other payment made by Tenant to Landlord),  shall have the
right to be  immediately  repaid by Tenant  the amount of all sums  expended  by

the  provisions  of this Lease,  including,  but not limited  to,  entering  the
Premises,  without  being liable to  prosecution  or any claims for damages,  in
order  to  accomplish  this  purpose.   Tenant  agrees  to  reimburse   Landlord
immediately  upon  demand  for any  expenses  which  Landlord  may incur in thus
effecting  compliance  with this Lease on behalf of Tenant,  and Tenant  further
agrees that  Landlord  shall not be liable for any damages  resulting  to Tenant
from such action, whether caused by the negligence of Landlord or otherwise.

            (v)   Landlord  may  declare  the  entire  amount  of  Base  Rental,
Additional  Rent and other sums which would have  become due and payable  during
the  remainder  of the  Term of this  Lease  to be due and  payable  immediately
without notice to Tenant,

            (vi)  Landlord may terminate this Lease and recover from Tenant,  as
full liquidated  damages,  all damages  Landlord may incur by reason of Tenant's
default,  which  damages shall be limited to (a) the amounts due and owing prior
to such  termination,  plus (b) the cost of recovering  the  Premises,  plus (c)
reasonable  attorney's fees and costs, plus (d) a sum which, at the date of such
termination,  equals the present  value  [discounted  at ten  percent  (10%) per
annum]  of(i) the Base  Rental,  Additional  Rent and all other sums which would
have been due and  payable by Tenant  hereunder  for the  remainder  of the Term
(including  any Extended  Term, if the Term of the Lease has been extended) less
(ii) the aggregate  reasonable rental value of the Premises for the same period,
accounting for me cost, time and other factors  necessary to relet the Premises,

shall not  thereafter  pursue  any of the other  remedies  set forth in  section
10(b)(i)-(iv)  to collect Base Rental and Additional  Rent due from Tenant.  The
foregoing  limitation of remedies is without  prejudice to  Landlord's  right to
enforce  Tenant's  indemnity  obligation  with  respect to claims,  damages  and
liabilities  (other than Base Rental and Additional  Rent) resulting to Landlord
by or through  Tenant's use and occupancy of the  Premises.  Landlord and Tenant
agree that such  amounts  constitute  a good faith  reasonable  estimate  of the
damages which might be suffered by Landlord upon the occurrence of a Default and
that it is  impossible  to estimate  more  precisely  such  damages.  Landlord's
receipt  of the  aforesaid  amount  is  intended  not as a  penalty  but as full
liquidated damages.

      (c)   Pursuit  by  Landlord  of any of the  foregoing  remedies  shall not
preclude the pursuit of general or special  damages  incurred,  or of any of the
other  remedies  provided  herein,  at  law  or in  equity;  provided,  however,
Landlord's  election  to  pursue  the  remedy  in  Section  10 (b) (v)  shall be
exclusive of any other remedies available to Landlord except as provided in said
Section 10 (b) (v).

      (d)   No act or thing done by Landlord or  Landlord's  employees or agents
during the Term shall be deemed an  acceptance  of a surrender of the  Premises.
Neither the mention in this Lease of any particular  remedy, nor the exercise by
Landlord of any particular remedy hereunder, at law or in equity, shall preclude
Landlord from any other remedy  Landlord might have under this Lease,  at law or
in  equity.  Any waiver of or redress of or any  violation  of any  covenant  or
condition  contained in this Lease or any of the Rules now or hereafter  adopted
by Landlord,  shall not prevent a subsequent  act,  which would have  originally
constituted  a  violation,  from  having all the force and effect of an original
violation.  The receipt by Landlord of Rent with  knowledge of the breach of any
covenant in this Lease shall not be deemed a waiver of such breach.

      (e)   Landlord's reentry,  demand for possession,  notice that the tenancy
hereby created will be terminated on the date therein  named,  institution of an
action of  unlawful  detainer or  ejectment  or the  entering of a judgment  for
possession in such action or any other act or acts resulting in the  termination
of Tenant's  right to possession of the Premises  shall not relieve  Tenant from
Tenant's

                                       12

<PAGE>

obligation to pay all sums due hereunder during the balance of the Term,  except
as herein expressly provided.  Landlord may collect and receive any Base Rental,
Additional Rent, or charges due from Tenant,  and the payment (.hereof shall not
constitute a waiver of or affect any notice or demand given,  suit instituted or
judgment obtained by Landlord,  or be held to waive, affect,  change,  modify or
alter the rights or remedies which Landlord has in equity or at law by virtue of
this Lease.

      (f)   The Base  Rental  is  calculated  for the Term of this  Lease  and a
substantial  portion of the Base Rental  includes  reimbursement  to Landlord of
direct  out-of-pocket  investment costs and expenses with respect to leasing the
Premises to the Tenant that  Landlord has incurred or will incur during the Term
for tenant  improvements,  leasing  commissions and other costs,  various tenant
concessions,  and other similar direct costs and expenses relating to Landlord's
investment in the Premises,  the aggregate  amount of which  Landlord has spread
over the entire Term.  Tenant  acknowledges  that Landlord will suffer  damages,
including,  but not limited to, such unreimbursed direct out-of-pocket costs and
expenses  unless Tenant pays to Landlord all the Base Rental due to Landlord for
the entire Term.

      (g)   In the event Landlord  commences any  proceedings  for nonpayment of
Base  Rental,  Additional  Rent or other  sums due  hereunder.  Tenant  will not
interpose any  counterclaim of whatever  nature or  description,  except for any
compulsory  counterclaim which may only be brought in any such proceeding.  This
shall not,  however,  be construed  as a waiver of the Tenant's  right to assert
such claims in any separate action or actions brought by the Tenant.

      (h)   Except as expressly provided in this Lease, Tenant hereby waives any
and every  form of  demand  and  notice  prescribed  by  statute  or other  law,
including  without  limitation  the notice of any  election of remedies  made by
Landlord  under  this  Section,  demand for  payment of any rent,  or demand for
possession.

      (i)   All rights and remedies of Landlord created or otherwise existing at
law or in  equity  are  cumulative  and the  exercise  of one or more  rights or
remedies shall not be taken to exclude or waive the right to exercise any other.

      (j)   Tenant  shall  and  hereby  agrees  to pay all  costs  and  expenses
incurred by Landlord,  including, but not limited to, reasonable attorneys' fees
Incurred  at the trial  and all  appellate  levels  and in  connection  with any
administrative  proceedings m enforcing  any of the covenants and  agreements of
this Lease or as a result of any action  brought by Landlord  against Tenant for
an  unlawful  detainer  of the  Premises,  and  all  such  costs,  expenses  and
attorneys'  fees shall be paid by Tenant to Landlord  within ten (10) days after
Landlord's written demand therefor.

      (k)   Notwithstanding anything in this Lease to the contrary. Tenant shall
have no claim,  and hereby waives the right to any claim,  against  Landlord for
money damages by reason of any refusal,  withholding  or delaying by Landlord of
any consent, approval or statement of satisfaction,  and in such event. Tenant's
only remedies therefor shall be an action for specific performance or injunction
to  enforce  any  such  requirements.  If the  result  of  any  such  action  or
arbitration shall be adverse to Landlord, Landlord shall be liable to Tenant for
Tenant's reasonable expenses and attorney's fees thereby incurred.

11.   ASSIGNMENT AND SUBLETTING

      (a)   Tenant  shall not sublet any part of the  Premises,  nor assign tins
Lease or any  interest  herein,  without the prior  written  consent of Landlord
which consent  shall not be  unreasonably  withheld.  Any sublease or assignment
made without  Landlord's  consent shall be void. For illustration  only, without
limiting  in any respect the reasons  Landlord  may  withhold  its consent to an
assignment or  subletting,  the  following are examples of reasons  Landlord may
withhold its consent:  (I) the proposed subtenant or assignee may, in Landlord's
judgment unreasonably burden the Building, its amenities or services (ii) if the
rate of  compensation,  including,  but not  limited to, all rent  requested  by
Tenant  for the  portion  of the  Premises  to be  subleased  or  subject  to an
assignment  of the Lease,  impacts  upon or impairs  Landlord's  ability to rent
space in the Building at the then market rate as offered by Landlord,  (iii) the
financial  statements or the business  experience  of the proposed  assignee are
unsatisfactory to Landlord, (iv) the proposed use of the Premises conflicts with
other uses within the Building,  (v) the pro$pective assignee or sublessee is an
existing  tenant of the Building and in  Landlord's  judgment  such  sublease or
assignment may affuct  Landlord's lease  relationship  with such tenant, or (vi)
Tenant's proposed  subletting or assignment will in Landlord's  judgment compete
with landlord's ability to lease other vacant space in the Building, Consent by

                                       12

<PAGE>

Landlord  to one  assignment  or  sublease  shall  not  destroy  or  waive  this
provision,  and all later  assignments and subleases shall likewise be made only
upon prior written consent of Landlord. If a sublease or assignment is consented
to by Landlord,  any  sublessees or assignees  shall become  liable  directly to
Landlord for all obligations of Tenant hereunder without relieving or in any way
modifying Tenant's liability hereunder.

      If Tenant  desires to assign this Lease or sublet the Premises or any part
thereof.  Tenant shall give Landlord  written notice at least sixty (60) days in
advance of the date on which Tenant desires to make such assignment or sublease,
which notice shall specify:  (a) the name and business of the proposed  assignee
or sublessee; (b) the amount and location of the space in the Premises affected;
(c) the proposed  effective date of the  subletting or  assignment;  and (d) the
proposed rental to be paid to Tenant by such sublessee or assignee.

      If Tenant  shall give such notice.  Tenant shall pay on demand  Landlord's
reasonable  costs,  including  attorneys'  fees  incurred  to  consider  and  as
necessary to document such transaction.  If Tenant notifies Landlord of Tenant's
intent to sublease or assign this Lease,  Landlord shall within thirty (30) days
from  receipt  of such  notice  (a)  consent  to  such  proposed  assignment  or
subletting;  (b) deny such consent (if Landlord  shall fail to notify  Tenant in
writing of such election  within said thirty (30) day period,  Landlord shall be
deemed to have elected to deny such consent); or (c) elect to cancel this Lease,
or lo reduce the  Premises by the area  requested to be subleased or assigned if
the area is less than the entire Premises.

      If Landlord's  election is to cancel or to reduce the area of the Premises
as provided in the foregoing  clause (c) (such election being referred to herein
as  "Landlord's  Modification  Election"),  Tenant shall have ten (10) days from
receipt of  Landlord's  Modification  Election  to notify  Landlord  of Tenant's
acceptance  of such  cancellation  or reduction or Tenant's  desire to remain in
possession o f the Premises  under this Lease for the  remainder of the Term. If
Tenant fails to notify  Landlord of Tenant's  election to accept  termination or
reduction or to continue as Tenant  hereunder,  such failure  shall be deemed an
election to terminate or have the area of the Premises  reduced,  as me case may
be, in accordance with Landlord's  Modification Election and such termination or
reduction  shall be effective at the end of the ten (10) day period provided for
above.  If Landlord  gives its consent to any such  assignment or sublease,  any
rent or other cost to the  assignee or  subtenant  for all or any portion of the
Premises  over and above the Rent  payable by Tenant for such space shall be due

portion of tills Lease.

            Term will be an amount  equal to the  "Market  Rate" (as  defined in
            paragraph  B below)  for the  Premises  for such  twelve  (12) month
            period,  and will increase on the first anniversary of such date, to
            reflect the increased  Market Rate (as defined in paragraph B below)

      other  concessions) for each twelve (12) month period occurring during the
      Renewal Term, or if no figures are available, then for comparable space in

      event  shall the  "Market  Rate" for the first  twelve  (12) months of the
      Renewal Term (or for any subsequent twelve (12) month period) ever be less
      than the annual  Base Rent  payable  under this Lease for the last  twelve
      (12)  months  of the  Primary  Term,  and the  above  limitation  shall be
      applicable  whether  or not  Market  Rate Is  determined  with or  without

      cannot mutually agree as to the "Market Rate",  for each twelve (12) month
      period  occurring  during  the  Renewal  Term  within  sixty  (60) days of
      Landlord's receipt of Renewal Notice, then, and in that event, the parties
      agree to submit  the  matter to  arbitration.  Such  arbitration  shall be
      conducted as follows;  Within ten (10) days of delivery of written  notice
      from either party to the other of its intention to arbitrate  this matter,

      period  occurring  during their  Renewal Term (based upon the standard set
      forth in this  subparagraph  B above)  within  thirty  (30)  days of their
      appointment.  If the  arbitrators are unable to reach an agreement for any
      twelve (12) month period,  they shall select a third person who shall also
      be licensed in a similar  manner,  whereupon the  determination  of Market
      Rent  for  such  period  shall be  resolved  by using  the mean of the two
      closest rental rate  determinations  for the period.  In arriving at their
      individual  determinations of "Market Rent", each arbitrator must consider
      the standards set forth above- The decisions of the  arbitrators  shall be
      binding,  the  expense of the  arbitrator  selected by each party shall be
      borne by the parties  selecting same. The cost of the third  arbitrator if
      needed, shall be split equally between the two parties.

lien or encumbrance of any kind  whatsoever,  whether  created by act of Tenant,
operation of law or otherwise,  to attach to or be placed upon Landlord's  title
or interest in the Premises,  and any and all liens and encumbrances  created by

removed of record. If Tenant shall fail to do so, then, in addition to any other
right or remedy, Landlord may, but shall not be obligated to, discharge the same
either by paying the  amounts  claimed or by deposit or by bonding  proceedings,
and in any such event  Landlord  shall be  entitled,  if Landlord so elects,  to
compel  the  prosecution  of an action for the  foreclosure  of such lien by the
lienor  and to pay the  amount  of the  judgment  in  favor of the  lienor  with
interest, costs and allowances. Any amount so paid by Landlord and all expenses,
including attorneys' fees, incurred by Landlord in connection  therewith,  shall
constitute  Rent.  Nothing  herein  contained  shall  obligate  Tenant to pay or
discharge any lien created by Landlord.

            B.    Master Landlord and Landlord's leasehold title to the Premises
is and always shall be  paramount  to the interest of Tenant and nothing  herein
contained  shall  empower  Tenant to do any act or to omit any act  which  would
encumber Master Landlord and Landlord's title.

                   ARTICLE 5: NAME; USE; HAZARDOUS SUBSTANCE.

name set forth in Article 1 unless  otherwise  agreed in writing by and  between
Landlord  and  Tenant.  Tenant  shall  conduct  its  business  at all times in a
first-class,  professional  and  businesslike  manner  consistent with reputable
business standards and practices.

      5.2   Operational Requirements.

            A.    Tenant shall  promptly and at its expense  procure any and all

                          ARTICLE 6: DEFAULTS, REMEDIES

      6.1   Bankruptcy. If:

            A.    there  shall be  filed  by or  against  Tenant,  in any  court
pursuant to any statute (either of the United States or of any state) a petition
in  bankruptcy or insolvency or for  reorganization  or  arrangement  or for the
appointment  of a receiver  or trustee of all or  substantially  all of Tenant's
property or the Premises, or

            B.    any attachment or execution is levied against this Sublease or
the estate created hereby, or

            C.    Tenant makes an assignment for the benefit of creditors; then,
upon any of the foregoing,  this Sublease, at the option of Landlord,  exercised
within a reasonable time after notice of any one or more of such events,  may be
terminated by notice thereof to Tenant.  Notwithstanding  the foregoing,  if any
such  proceeding is filed  involuntarily  against Tenant and such  proceeding is
discharged  within 60 days after filing of the  proceeding,  then Landlord shall
not have the right as a result thereof to terminate this Sublease.  Whether such
termination  occurs prior to or during the Term,  neither  Tenant nor any person
claiming through or under Tenant by virtue of any statute or of any order of any
court shall be entitled to possession or to remain in possession of the Premises
but shall forthwith quit and surrender the Premises.

      6.2   Default. If Tenant defaults in the payment of Rent for ten (10) days
or in performing  or observing any of the other  provisions of this Sublease for
thirty days, or if the Premises  become  abandoned,  then, in any one or more of
such events,  upon Landlord serving a written notice upon Tenant  specifying the
nature of said  default  and upon the  expiration  of ten (10) days  after  such
notice is given,  if Tenant  shall  have  failed to comply  with or remedy  such
default (or if the said default shall be other than in payment of Rent and is of
a nature that the same cannot be  completely  cured or remedied  within said ten
(10) day period,  if Tenant shall not have commenced  curing such default within
such 5-day period and thereafter with  reasonable  diligence fails in good faith
to proceed to remedy or cure such  default)  then  Landlord  may serve a written
notice of termination  of this Sublease upon Tenant.  Upon the date specified in
such  notice,  this  Sublease  and the Term  shall  end and  expire as fully and
completely as if such date were the day herein  definitely fixed for the end and
expiration  of the  Sublease  and the  Term,  and  Tenant  shall  then  quit and
surrender the Premises to Landlord but Tenant shall remain liable as hereinafter
provided.

      6.3   Landlord's Remedies.

                                       5
<PAGE>

            A.    In case of any  termination of this  Sublease,  or re-entry by
summary proceedings or otherwise, then, in such event:

                  1.    Rent shall be paid up to the time of such termination or
re-entry  together with such expenses as Landlord may incur for attorneys' fees,
brokerage, and putting the Premises in good order, or for preparing the same for
re-rental; and

                  2.    Landlord  may re-let the  Premises  or any part or parts
thereof, either in the name of Landlord or otherwise,  for a term or terms which
may at Landlord's option be less than or exceed the period which would otherwise
have  constituted the balance of the Term and Landlord may grant  concessions or
free rent or charge a different rental than that in this Sublease; and

                  3.    In the event of a breach or threatened  breach by Tenant
of any of the  provisions  of this  Sublease,  Landlord  shall have the right of
injunction  and the right to invoke any remedy allowed at law or in equity as if
re-entry,  summary  proceedings  and other  remedies  were not herein  provided.
Tenant hereby  expressly  waives any and all rights of redemption  granted by or
under any  present  or  future  laws in the event of  Tenant  being  evicted  or
dispossessed for any cause, or in the event of Landlord obtaining  possession of
the Premises, by reason of the breach by Tenant of any of the provisions of this
Sublease; and

                  4.    If Tenant shall default in the observance or performance
of any  provisions of this Sublease on Tenant's part to be observed or performed
under or by virtue of any of the provisions in this Sublease,  then Landlord may
immediately or at any time thereafter and without  notice,  perform the same for
the account of Tenant,  and if  Landlord  makes any  expenditures  or incurs any
obligations  for the  payment  of  money or  expenses  in  connection  therewith
including,  but not limited to,  reasonable  attorneys'  fees,  in  instituting,
prosecuting or defending any action or proceeding, such sums paid or obligations
or  expenses  incurred  with  interest  and costs shall be payable by Tenant and
deemed to be additional rent.

      6.1   Remedies Cumulative. No reference to any specific right or remedy in
this Sublease  shall preclude  Landlord from  exercising any other right or from
having any other remedy or from maintaining any action to which it may otherwise
be entitled now or later under any statute or rule of law. Landlord's failure to
insist upon strict  performance of any provision of this Sublease or to exercise
any right herein  contained shall not be deemed a waiver or  relinquishment  for
the future of such provision or of any other provision of this Sublease, but the
same shall remain in full force and effect. Landlord will use reasonable efforts
to mitigate damages.

                      ARTICLE 7: ASSIGNMENT; SUBORDINATION;
                         QUIET ENJOYMENT; MASTER LEASE.

      7.1   Assignment and  Subletting.  Tenant shall not transfer this Sublease
or Tenant's  interest  in this  Sublease  or the  Premises  or any part  thereof
without  Landlord's  prior written  consent as well as full  compliance with any

                                       6
<PAGE>

requirements  for  subletting  pursuant  to the terms of the Master  Lease.  Any
attempted  transfer in  violation  of this  Section  shall be void and confer no
rights upon any third person. The term "transfer" in this Article shall include,
but not be limited to, any assignment,  sublease,  or entry into any mortgage or
other encumbrance of this Sublease as well as any transfer of this Sublease from
Tenant  by  merger,  consolidation,   liquidation,  assignment  for  benefit  of
creditors or by operation of law. If this Sublease is  transferred  or if all or
part of the Premises is sublet or occupied by anyone other than Tenant, Landlord
may collect  Rent from the  transferee,  subtenant or occupant and apply the net
amount  collected to the Rent herein  reserved,  but no such collection shall be
deemed a waiver of this covenant, or the acceptance of the transferee, subtenant
or occupant as lessee,  or a release of Tenant from the further  performance  by
Tenant of  covenants  on the part of Tenant  herein  contained.  The  consent by
Landlord to a transfer  shall not be construed to relieve  Tenant from obtaining
the express  consent of Landlord to any further  transfer,  and no such transfer
shall  relieve  or  discharge  Tenant of or from any  liability,  whether  past,
present or future,  under this  Sublease  and Tenant  shall  remain fully liable
hereunder.

      7.2   Master Lease.  The rights and interest of Tenant under this Sublease
are subject and  subordinate to the Master Lease.  Upon Tenant's  request and at
Tenant's expense,  Landlord will use reasonable efforts to enforce provisions of
the Master Lease following a default by Master  Landlord which affects  Tenant's
use or occupancy of the Premises.

                             ARTICLE 8: END OF TERM

      8.1   Surrender.

            A.    If not sooner  terminated  as herein  provided,  this Sublease
shall expire at the end of the Term without the  necessity of notice from either
Landlord or Tenant.  Tenant  hereby  waives  notice to vacate the  Premises  and
agrees that Landlord  shall be entitled to the benefit of all  provisions of law
respecting the summary  recovery of possession of premises from a tenant holding
over to the same extent as if statutory notice had been given.

            B.    Unless  otherwise  agreed in writing,  all improvements to the
Premises  by Tenant or by  Landlord  for Tenant  shall  become the  property  of
Landlord upon expiration or earlier termination of this Sublease.

            C.    If this Sublease  expires or is terminated  for any reason and
Tenant fails to remove its personal  property and other items from the Premises,
if any,  prior to such  expiration  or  termination,  then in such  event all of
Tenant's personal property  remaining in the Premises shall thereupon become the
property  of  Landlord,  without  further  act by either  party  hereto,  unless
Landlord  elects to require  their  removal in which case Tenant shall  promptly
remove same.  In the event Tenant  fails to remove such  property,  Landlord may
handle, remove or store the same at the risk and expense of Tenant, and Landlord
shall in no event be responsible for the preservation or safekeeping thereof.

                                       7
<PAGE>

      8.2   Holding Over.  Should Tenant or any party claiming under Tenant hold
over in possession of the Premises,  or any part thereof,  at the  expiration or
earlier  termination of this Sublease,  such holding over shall not be deemed to
extend the Term but shall be an unlawful detainer.  In such event, Tenant shall,
upon demand,  pay to Landlord the Rent due  immediately  preceding the hold-over
period during any period which Tenant shall hold the Premises after the Term has
expired and Tenant shall comply with all of the provisions of this Sublease, all
as if such period were included in the Term.  All provisions of this Sublease on
the part of Tenant to be performed or observed  shall apply during such holdover
period.  Tenant  shall hold  Landlord  harmless  from all  liability  and damage
resulting from Tenant's failure to surrender the Premises upon the expiration of
the Term including, but not limited to, claims made by a successor tenant.

                         ARTICLE 9: AMENDMENTS; NOTICES

      9.1   Amendments.  No amendment,  supplement,  modification or addition to
this Sublease shall be binding upon Landlord or Tenant unless in writing, signed
by Landlord and Tenant and mutually delivered.

      9.2   Notices. All notices,  demands,  requests,  consents,  approvals and
other  instruments  required or permitted to be given  pursuant to this Sublease
(collectively,  "notice") shall be in writing and shall be sent by registered or
certified mail return receipt requested,  or by national private courier if such
courier will certify as to the date and time of such delivery, in each case with
postage or delivery fees prepaid and  addressed to the party at the  address(es)
specified  below, and such notice so mailed or delivered shall be deemed to have
been delivered when delivered or refused. Notices sent by facsimile transmission
shall not satisfy the requirements of this Section.

                   ARTICLE 10: NO WAIVER; COUNTERCLAIMS; VENUE

                                       8
<PAGE>

      10.1  No Waiver.  No provision of this  Sublease  will be deemed waived by
either party unless expressly  waived in writing.  No waiver shall be implied by
delay or any other act or omission of either  party.  No waiver of any provision
of this Sublease  shall be deemed a waiver of such provision with respect to any
subsequent  matter  relating to such  provision,  and Landlord's  consent to any
action by Tenant shall not constitute a waiver of the  requirement for obtaining
Landlord's  consent  respecting  any  subsequent  action.  Acceptance of Rent by
Landlord  shall not  constitute  a waiver of any breach by Tenant of any term or
provision  of this  Sublease.  No  acceptance  of a lesser  amount than the Rent
herein  stipulated  shall be deemed a waiver of Landlord's  right to receive the
full amount due, nor shall any  endorsement or statement on any check or payment
or any  letter  accompanying  such  check or  payment  be deemed  an accord  and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's  right to recover the full amount due. The  acceptance  of Rent or of
the  performance  of any other  provision  from any  party  other  than  Tenant,
including any transferee,  shall not constitute a waiver of Landlord's  right to
approve any transfer.

      10.2  Counterclaims,  Venue And Jury Trial. IN THE INTEREST OF OBTAINING A
FASTER AND LESS  COSTLY  HEARING OF ANY  DISPUTE,  EACH OF  LANDLORD  AND TENANT
HEREBY EXPRESSLY WAIVES TRIAL BY JURY IN ANY ACTION,  PROCEEDING OR COUNTERCLAIM
BROUGHT  BY EITHER  PARTY  AGAINST  THE OTHER AND ANY  RIGHTS TO A TRIAL BY JURY
UNDER ANY STATUTE,  RULE OF LAW OR PUBLIC POLICY IN  CONNECTION  WITH ANY MATTER
WHATSOEVER ARISING OUT OF OR IN ANY WAY RELATING TO THIS SUBLEASE,  THE PREMISES
OR THE CENTER.  Although such jury waiver is intended to be  self-operative  and
irrevocable,  Landlord and Tenant each further agree,  if requested,  to confirm
such  waivers  in  writing  at the  time of  commencement  of any  such  action,
proceeding or  counterclaim.  Any action or  proceeding  brought by either party
against the other in any way relating to this Sublease or the Premises  shall be
heard in the county where the Premises  are  located.  If Landlord  commences an
action  seeking  possession of the  Premises,  Tenant agrees not to interpose by
consolidation  of actions,  removal to chancery or otherwise,  any  counterclaim
claim for  set-off,  recoupment  or deduction  of Rent,  or other claim  seeking

Premises to comply with the laws, ordinances, rules or regulations of any public
authority or that Landlord may deem otherwise  necessary or desirable.  Landlord
may install any and all materials,  equipment and pipes, ducts, conduits,  wires
and other mechanical equipment serving other portions,  tenants and occupants of

Tenant.  Landlord may enter the Premises following reasonable notice to show the
Premises to  prospective  purchasers,  mortgagees  and  tenants.  No exercise by
Landlord of any rights  provided in this  Section  shall  entitle  Tenant to any

                                    EXHIBIT B
                              ADDITIONAL PROVISIONS

      Notwithstanding  the  terms of the  Sublease  to  which  this  exhibit  is
attached the Landlord and Tenant further agree as follows:

      1.    Joinder of Master  Landlord:  The Master  Landlord has joined in the
            execution of this Sublease thereby  consenting to any and all of the
            terms,  conditions  and  provisions  therein  set forth and  further
            consenting to the provisions of this Exhibit "B."

      2.    Nondisturbance  of Tenant:  Landlord,  Tenant  and  Master  Landlord
            acknowledge  and agree that the Tenant is  subleasing  the  Premises
            which is only part and parcel of the property presently being leased
            by the Landlord from the Master  Landlord.  Due to the foregoing,  a
            default by the  Landlord  pursuant to the terms of the Master  Lease
            will adversely impact the Tenant's possessory rights of the Premises
            in the event the  Tenant is not in  default  under the terms of this
            Sublease.  In order to protect the Tenant's  rights  hereunder,  the
            Master Landlord agrees as follows:

            A.    That in the event of a default  under the Master  Lease by the
                  Landlord,  the  Master  Landlord  shall give not less than ten
                  (10) days  written  notice of said  default  to the  Tenant in
                  order to provide  the Tenant  with  knowledge  of any  default
                  under the terms of the Master Lease; and

            B.    Provided that the Tenant is not in default in the  performance
                  of any of the terms,  covenants or  conditions of the Sublease
                  on the Tenant's part to be  performed,  then in such event the
                  Tenant's  possession  and  occupancy  of the  Premises and the
                  Tenant rights and  privileges  under the Sublease shall not be
                  diminished  or interfered  with by the Master  Landlord in the
                  exercise  of any of the  Master  Landlord's  rights  under the
                  Master Lease;  it being the express intent of the parties that
                  in the event the Master  Landlord  exercises any of its rights
                  under the Master  Lease  against  the  Landlord,  then in such
                  event the Master  Landlord agrees to enter into a separate and
                  independent  Lease  Agreement with the Tenant in the same form
                  and  content  of  the  Master  Lease  but  requiring  security
                  deposits and other  related  matters to be calculated on a pro
                  rata  square  footage  basis where the  numerator  will be the
                  square footage of the Premises and the denominator will be the
                  total square footage of the Initially  Leased Premises and the
                  First Expansion Space as more  particularly  defined under the
                  Master Lease.

            3.    Direct Lease With Master  Landlord:  The  Landlord  Tenant and
                  Master Landlord acknowledge and agree that notwithstanding the
                  terms  set  forth in  paragraph  2B  above,  that  the  Master
                  Landlord  and  the  Tenant  may  enter  into  a  separate  and
                  independent  Lease  agreement with respect to the Premises (as
                  defined in the Sublease). In the event the Master Landlord and
                  Tenant  agree to use their best  efforts to enter into a Lease
                  agreement  in the same form and  content as the Master  Lease,
                  modified to accommodate  the reduced  rental space,  providing
                  for revised  security  deposits,  proration  requirements,  or
                  otherwise.
