                               KRONOS INCORPORATED
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE A - General

The accompanying  unaudited condensed  consolidated financial statements include
all  adjustments,  consisting  of normal  recurring  accruals,  that  management
considers  necessary for a fair presentation of the Company's financial position
and results of operations as of and for the interim periods  presented  pursuant
to the rules and regulations of the Securities and Exchange Commission.  Certain
footnote  disclosures  normally  included in  financial  statements  prepared in
accordance with generally accepted accounting  principles have been condensed or
omitted  pursuant to such rules and  regulations,  although the Company believes
the  disclosures  in  these  financial  statements  are  adequate  to  make  the
information  presented not misleading.  These condensed  consolidated  financial
statements  should be read in conjunction with the Company's  audited  financial
statements  for the  fiscal  year  ended  September  30,  1998.  The  results of
operations  for the  three  and six month  periods  ended  April 3, 1999 are not
necessarily  indicative of the results for a full fiscal year.  Certain  amounts
have been reclassified in fiscal 1998 to permit comparison with fiscal 1999.

NOTE B  -  Fiscal Quarters

The Company utilizes a system of fiscal quarters.  Under this system,  the first
three  quarters  of each  fiscal  year end on a  Saturday.  However,  the fourth
quarter of each fiscal year will always end on  September  30.  Because of this,
the number of days in the first  quarter  (94 days in fiscal 1999 and 95 days in
fiscal  1998) and fourth  quarter  (89 days in fiscal 1999 and 88 days in fiscal
1998) of each  fiscal  year  varies  from  year to year.  The  second  and third
quarters of each fiscal year will be exactly  thirteen  weeks long.  This policy
does not have a material  effect on the  comparability  of results of operations
between quarters.

NOTE C - Software Revenue Recognition

In November 1997, the Accounting  Standards  Executive  Committee (AcSEC) issued
Statement of Position  (SOP) 97-2,  "Software  Revenue  Recognition",  which the
Company  adopted in the first  quarter of fiscal 1999.  The adoption of SOP 97-2
did not have a material effect on the Company's financial statements.

NOTE D - Comprehensive Income

In September 1997, the Financial  Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting  Comprehensive Income" ("SFAS
No. 130),  which the Company  adopted in the first quarter of fiscal 1999.  SFAS
No.  130  establishes  standards  for  reporting  comprehensive  income  and its
components.  Comprehensive  income  is  defined  as the  change  in  equity of a
business  enterprise  during a period  from  transactions  and other  events and
circumstances from non-owner sources and includes all changes in equity during a
period except those resulting from  investments by owners and  distributions  to
owners.


For the  three  and six  months  ended  April 3,  1999 and  April 4,  1998,  the
Company's comprehensive income was as follows (in thousands):

</TABLE>

During the quarter  ended  April 3, 1999,  the  Company  sold its South  African
subsidiary  to an unrelated  third party.  As a result of the  transaction,  the
cumulative  equity  adjustment from  translation of the  subsidiary's  financial
statements  in the  amount of $.5  million  was  included  as a charge to pretax
income.

NOTE E - Stock Split

The Company's Board of Directors  approved a three-for-two  stock split effected
in the  form  of a 50%  stock  dividend  that  was  paid  on  March  9,  1999 to
stockholders of record on February 23, 1999.  Accordingly,  the  presentation of
shares  outstanding  and  amounts per share have been  restated  for all periods
presented  to reflect  the  split.  The par value of the  additional  shares was
transferred from additional paid-in capital to Common Stock.

On  November  17,  1995,  the  Company's  Board of  Directors  adopted  a Rights
Agreement.  Under the  Agreement,  the Company  distributed  to  stockholders  a
dividend of one Right for each outstanding share of Common Stock. As a result of
the stock split,  each  stockholder has forty  four-hundreds of a Right for each
share of Common Stock held as of the Record Date.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
 of Operations

Forward Looking Statements

         This discussion includes certain  forward-looking  statements about the
Company's business and its expectations. Any such statements are subject to risk
that could cause the actual results to vary materially from expectations.  For a
further  discussion of the various risks that may affect the Company's  business
and expectations, see "Certain Factors That May Affect Future Operating Results"
at the end of  Management's  Discussion and Analysis of Financial  Condition and
Results of Operations.

Results of Operations

       Revenues.  Revenues  for the second  quarter of fiscal  1999  amounted to
$61.7 million as compared to $46.5  million for the second  quarter of the prior
year.  Revenues  for the first six months of fiscal 1999 were $114.8  million as
compared to $91.0  million  for the first six months of the prior year.  Revenue
growth was 33% and 26% in the three and six month  periods  ended April 3, 1999,
respectively,  as compared to 18% and 19% for each of the comparable  periods of
the prior year.  The  revenue  growth in the three and six month  periods  ended
April 3, 1999 was  principally  driven by  customer  demand in all  distribution
channels.

       Product  revenues for the second quarter of fiscal 1999 amounted to $40.6
million as compared to $30.1  million for the second  quarter of the prior year.
Product  revenues for the first six months of fiscal 1999 were $73.8  million as
compared to $59.9  million  for the first six months of the prior year.  Product
revenue  growth of 35% and 23% in the three and six month periods ended April 3,
1999, respectively,  increased from 15% in each of the comparable periods of the
prior year.  Product  revenue  growth in the three and six month  periods  ended
April 3, 1999 was principally  driven by sales of the Company's  products to new
customers  as well as sales into the  Company's  existing  customer  base in the
second quarter. Contributing significantly to this growth were software revenues
that  increased 58% in the three month period ended April 3, 1999 as compared to
34% in the comparable period of the prior year.

       Service  revenues for the second quarter of fiscal 1999 amounted to $21.0
million as compared to $16.4  million for the second  quarter of the prior year.
Service  revenues for the first six months of fiscal 1999 were $41.0  million as
compared with $31.2 million for the first six months of the prior year.  Service
revenue  growth of 29% and 31% in the three and six month periods ended April 3,
1999,  respectively,  increased from 23% and 26% for  comparable  periods of the
prior year.  The growth in service  revenues in the three and six month  periods
ending  April 3, 1999  reflects  an  increase in  maintenance  revenue  from the
expansion  of the  installed  base and an increase  in the level of  maintenance
contracts  and  professional  services  accompanying  sales to new customers and
sales to the Company's existing customer base.
       Gross Profit. Gross profit as a percentage of revenues was 64% and 62% in
the three and six month periods ended April 3, 1999,  respectively,  as compared
with 61% in the comparable  periods of the prior year. The  improvement in gross
profit was evidenced in both product and service gross profit.

       Product gross profit as a percentage of product  revenues was 77% and 76%
in the three and six month periods ended April 3, 1999, respectively, increasing
from 74% and 75% for the comparable  periods of the prior year. The  improvement
in  product  gross  profit  in both  periods  is  primarily  attributable  to an
increased proportion of product revenues generated by software,  which typically
generates  higher gross profit than other  products.  The software  component of
product sales  increased to 48% and 47% in the three and six month periods ended
April  3,  1999,  respectively,  as  compared  to 41% and  44%  for  each of the
comparable  periods of the prior year.  Service  gross profit as a percentage of
service revenues was 39% in the three and six month periods ended April 3, 1999,
respectively,  increasing from 36% and 34%, respectively, for comparable periods
of the prior year.  The  increase  in service  gross  profit in both  periods is
primarily attributable to the growth in service revenues without a proportionate
increase  in  service  expenses.  This  has  been  accomplished  by  more  fully
leveraging  service  resources and  improving the  efficiency in the delivery of
services.  The Company  anticipates that service gross profit as a percentage of
service revenues should be approximately 38% to 40% over the remainder of fiscal
1999.

       Expenses.  Total operating  expenses as a percentage of revenues were 53%
in each of the three and six month  periods  ended April 3, 1999, as compared to
51% and 52%,  respectively,  in the comparable  periods of the prior year. Sales
and marketing expenses as a percentage of revenues were 35% in the three and six
month periods  ended April 3, 1999 as compared to 34% and 35% in the  comparable
periods of the prior year. Engineering expenses as a percentage of revenues were
11% in each of the three and six month  periods ended April 3, 1999, as compared
to 10% in the comparable periods of the prior year. Engineering expenses of $6.6
million  and $4.6  million  in the  second  quarter  of  fiscal  1999 and  1998,
respectively,  are net of capitalized software development costs of $2.2 million
and $1.6 million,  respectively.  Engineering expenses of $12.6 million and $8.9
million in the first six months of fiscal 1999 and 1998,  respectively,  are net
of  capitalized  software  development  costs of $4.2 million and $3.0  million,
respectively.  The growth in  engineering,  research  and  development  expenses
results  primarily from the development of new products in the client/server and
Windows environments.

       General and  administrative  expenses as a percentage of revenues were 6%
in the three and six month  periods ended April 3, 1999 as compared to 7% in the
comparable  periods of the prior year. Other (income)  expense,  net amounted to
less than 1% of revenues for all periods presented.  Other (income) expense, net
is  composed   primarily  of  amortization  of  intangible   assets  related  to
acquisitions  made by the Company  which is offset by interest  income earned on
its investments.  In the second quarter of fiscal 1999, other (income)  expense,
net also includes an immaterial  charge resulting from the Company's sale of its
South African subsidiary. This charge relates to the write off of the cumulative
equity adjustment from the translation of the subsidiary's financial statements.

       Income  Taxes.  The  provision for income taxes as a percentage of pretax
income was 33% and 35% in the three and six month  periods  ended April 3, 1999,
respectively,  as compared to 38% in each of the comparable periods of the prior
year. The reduction in the Company's  effective  income tax rate in both periods
is primarily  attributable to tax benefits  resulting from the Company's sale of
its South  African  subsidiary as well as  utilization  of foreign net operating
loss carryforwards. The Company anticipates the effective income tax rate should
be approximately 35% for the remainder of the fiscal year.

Liquidity and Capital Resources

         Working  capital  as of April 3,  1999,  amounted  to $33.9  million as
compared  with $45.1  million at  September  30,  1998.  The  decline in working
capital is primarily  attributable to the Company's  investment of $19.9 million
of its  cash  and  equivalents  in long  term  marketable  securities.  Cash and
equivalents and marketable  securities increased to $63.6 million as of April 3,
1999 as compared to $51.8 million at September  30, 1998.  Cash  generated  from
operations  increased  to $22.6  million in the first six months of fiscal  1999
from $13.7 million in the first six months of the prior year, principally due to
increased  earnings  and deferred  maintenance  revenues as well as increases in
depreciation and amortization  charges.  The Company's increase of approximately
$1.0  million  in its  investment  in  equipment  in the first six months of the
fiscal year as compared to the same period of the prior year is principally  due
to increased  investments in the Company's engineering and service organizations
as well as investments  related to the planned relocation of the Company's world
headquarters.  Cash generated from  operations was more than  sufficient to fund
investments in equipment and capitalized  software  development  costs. In April
1999, the Company acquired a parcel of land located in Chelmsford, Massachusetts
for  the  construction  of  a  new  approximately   129,000  square  foot  world
headquarters facility. The Company anticipates it will spend approximately $18.0
million in the construction of the facility over the next 12 months. The Company
is also assessing several  acquisition  opportunities that may be completed over
the next three months,  although there can be no assurance that these
acquisitions will be completed. 
The Company expects to fund its investments in equipment,  software  development
costs and  acquisitions  over the  remainder of its fiscal year as well as costs
related  to the  construction  of the  new  facility  with  available  cash  and
investments and operating cash flow.

Certain Factors That May Affect Future Operating Results

         Except for historical matters,  the matters discussed in this Quarterly
Report on Form 10-Q are  "forward-looking  statements" within the meaning of the
Private  Securities  Litigation  Reform  Act of 1995 (the  "Act").  The  Company
desires  to take  advantage  of the  safe  harbor  provisions  of the Act and is
including  this  statement  for the express  purpose of  availing  itself of the
protection  of the safe harbor with  respect to all forward  looking  statements
that involve risks and uncertainties.

         The Company's actual operating  results may differ from those indicated
by forward  looking  statements  made in this Quarterly  Report on Form 10-Q and
presented  elsewhere  by  management  from time to time  because  of a number of
factors including the potential  fluctuations in quarterly  results,  timing and
acceptance  of new product  introductions  by the  Company and its  competitors,
competitive  pricing  pressures,   the  dependence  on  alternate   distribution
channels,  potential  effects of the century change,  the ability to attract and
retain sufficient technical personnel,  and the dependence on the Company's time
and attendance  product line and on key vendors,  as further described below and
in the Company's  Annual Report on Form 10-K for the fiscal year ended September
30, 1998, which factors are specifically incorporated by reference herein.

         Potential  Fluctuations in Quarterly Results.  The Company's  quarterly
operating  results may fluctuate as a result of a variety of factors,  including
the timing of the  introduction of new products and product  enhancements by the
Company and its competitors,  market acceptance of new products, mix of products
sold, the purchasing patterns of its customers, competitive pricing pressure and
general economic conditions.  The Company historically has realized a relatively
larger percentage of its annual revenues and profits in the fourth quarter and a
relatively smaller percentage in the first quarter of each fiscal year, although
there can be no assurance  that this pattern will continue.  In addition,  while
the  Company  has  contracts  to supply  systems  to certain  customers  over an
extended period of time,  substantially all of the Company's product revenue and
profits  in each  quarter  result  from  orders  received  in that  quarter.  If
near-term   demand  for  the  Company's   products  weakens  or  if  significant
anticipated  sales in any  quarter do not close  when  expected,  the  Company's
revenues for that quarter will be adversely affected.  The Company believes that
its  operating  results  for any one period are not  necessarily  indicative  of
results for any future period.

         Product  Development and  Technological  Change.  Continual  change and
improvement  in computer  software  and  hardware  technology  characterize  the
markets for frontline labor  management  systems.  The Company's  future success
will depend largely on its ability to enhance its existing  product lines and to
develop new products and  interfaces  to third party  products on a timely basis
for the increasingly sophisticated needs of its customers.  Although the Company
is continually  seeking to further enhance its product  offerings and to develop
new products and  interfaces,  there can be no assurance that these efforts will
succeed, or that, if successful,  such product enhancements or new products will
achieve widespread market acceptance, or that the Company's competitors will not
develop and market  products  which are  superior to the  Company's  products or
achieve greater market acceptance.

         Competition.   The  frontline  labor  management   industry  is  highly
competitive.  Competition is increasing as  competitors  in related  industries,
such as human resources  management,  payroll processing and enterprise resource
planning  (ERP) enter the market.  Advances in software  development  tools have
accelerated  the  software   development  process  and,  therefore,   can  allow
competitors  to penetrate  certain of the  Company's  markets.  Maintaining  the
Company's  technological  and other  advantages  over  competitors  will require
continued  investment by the Company in research and  development  and marketing
and  sales  programs.  There  can be no  assurance  that the  Company  will have
sufficient  resources  to  make  such  investments  or be able  to  achieve  the
technological  advances  necessary  to  maintain  its  competitive   advantages.
Increased  competition  could adversely affect the Company's  operating  results
through price reductions and/or loss of market share.

         Dependence on Alternate  Distribution Channels. The Company markets and
sells its products through its direct sales  organization,  independent  dealers
and OEMs. For the fiscal year ended September 30, 1998, approximately 20% of the
Company's revenue was generated through sales to dealers and OEMs.  Reduction in
the sales efforts of the Company's  major dealers and/or OEMs, or termination or
changes in their  relationships with the Company,  could have a material adverse
effect on the results of the Company's operations.

         Year 2000.  The Company has an executive  level  steering  committee to
identify and resolve Year 2000 issues  associated  with the  Company's  internal
systems  (both  information  technology  ("IT") and non-IT),  the  Company's own
products and services,  the status of third party  products  distributed  by the
Company to its  customers as well as the Year 2000  readiness  of the  Company's
suppliers.  The Company has  completed an  assessment of all of its principal IT
systems,  which  include  manufacturing,   distribution,  customer  service  and
financial  systems.   The  Company  has,  with  the  assistance  of  an  outside
consultant,  tested its principal  internal  enterprise  resource planning (ERP)
system and believes it to be year 2000 compliant. This ERP system includes order
entry,  material resource planning,  master production  scheduling,  purchasing,
shipping and financial  systems.  The Company has identified Year 2000 issues in
other less  significant  IT systems,  and expects to resolve  those  issues,  by
replacements and/or upgrades,  by mid-1999.  The Company is currently performing
an  assessment  of certain  non-IT  systems and expects  that  assessment  to be
completed  by  mid-1999.  Examples of these  non-IT  systems  include the
Company's telephone systems. The Company will replace prior to the end of       
October, 1999, certain stand alone shop floor test equipment to ensure
year 2000 compliance.  The Company does not plan to
assess specifically its facility management systems, or the external forces such
as utility or transportation  Year 2000 compliance failures that might generally
affect industry and commerce. Although the Company is not currently aware of any
material  operational  issues or costs associated with preparing its internal IT
and non-IT  systems  for the Year 2000,  the  Company  may  experience  material
unanticipated problems and costs caused by undetected errors or defects in these
internal systems.

         The Company's Year 2000 compliance plan includes  designing its current
products to meet the Company's  definition of "Year 2000  Compliant" and testing
the most recent versions of its current products to determine  whether they meet
that definition.  Testing of products  currently  manufactured by the Company is
approximately  95%  completed  and is expected to be finished by the end of June
1999.  The  Company  has  warranted,  and may in the  future  warrant to certain
customers  that its products  will work in the Year 2000 and beyond.  Generally,
for products that have been identified to date as needing upgrades/new  versions
to  address  Year 2000  issues,  the  Company  has those  upgrades/new  versions
available to customers for purchase or under maintenance agreements. One of the
Company's products, which was sold in low volumes, has a Year 2000 deficiency   
for which there is no upgrade/new version currently available, but the Company
intends to correct that deficiency in the product's next
maintenance release.  Some of the
Company's  customers are using products and/or product versions that the Company
has not tested, and does not support,  for Year 2000 compliance.  The Company is
encouraging  these customers to migrate to current  products/versions  that meet
the Company's Year 2000 compliance  definition.  It is possible that the Company
may  experience  increased  expenses in  addressing  migration  issues for these
customers.  In  addition,  the Company does not intend to test any of its custom
software products for Year 2000 compliance.

         For  third  party  products  that  the  Company  distributes  with  its
products,   the  Company  has  sought   information   and  assurances  from  the
manufacturers  concerning  those  products' Year 2000  compliance  status.  As a
result,  the Company has  identified  certain  third  party  products  that will
require an upgrade to be Year 2000 compliant and is currently notifying affected
customers and encouraging  them to upgrade.  The Company expects to complete its
assessment of those third party products by mid-1999.

         Despite  the  testing  of  its  own  products  and  efforts  to  obtain
assurances on third party  products,  errors or defects in such  products  could
result in delay or loss of revenue,  diversion of development resources,  damage
to the Company's  reputation,  or increased  service and warranty costs,  any of
which could materially affect the Company's business,  results of operations, or
financial  condition.   In  addition,  the  unprecedented  nature  of  potential
litigation  regarding Year 2000 compliance issues makes it uncertain whether the
Company will be affected by such litigation.

         The Company has  completed its  systematic  inquiry of key suppliers to
assess their Year 2000 readiness.  The Company is not aware of any problems that
would  materially  affect its  business,  results  of  operations  or  financial
condition,  but the Company has no means of ensuring  that  assurances  received
from such  suppliers are accurate.  The inability of such suppliers to meet Year
2000 requirements  could materially impact the ability of the Company to procure
material from these  suppliers and to meet its obligations to supply products to
its customers.

         The Company does not currently have any information concerning the Year
2000  compliance  status of its  customers.  As with  other  similarly  situated
companies,  if the Company's  current or future  customers  fail to achieve Year
2000  compliance or if they divert  expenditures to address Year 2000 compliance
problems, the Company's business,  results of operations, or financial condition
could be materially affected.

         The  Company  has not yet  developed  a  contingency  plan on Year 2000
readiness.  The  Company  is  currently  assessing  the need for such a plan and
anticipates completing that assessment by mid-1999.

         The costs associated with the Company's Year 2000 plan have been funded
from  operating  cash flows and have been charged to  operations.  To date,  the
Company has incurred approximately $.8 million of incremental costs and expects,
on a cumulative  basis, total costs to be approximately  $1.2 million to address
its internal IT and non-IT  systems and to address Year 2000 compliance problems
in its own products and in third party products distributed with its 
products.  The Company does not separately  track the
internal costs associated with its Year 2000 plan,  which are primarily  payroll
costs for its information systems employees, support and technical personnel and
the Year 2000 steering  committee.  The costs described herein, and the costs to
accomplish the other elements of the Company's Year 2000 plan, have not been and
are not expected to be material to the Company's financial position,  results of
operations or cash flows. The cost of completing the Year 2000 plan and the date
on which  the  Company  believes  the  plan  will be  complete  are  based  upon
management's  best  estimates  derived by using  numerous  assumptions of future
events, including the continued availability of certain resources.  There can be
no guarantee  that these  estimates  will be achieved and the actual results may
differ  materially  from those  anticipated.  Specific  factors that might cause
these  differences  include without  limitation,  the  availability  and cost of
personnel  trained in this area,  the  ability  to make  timely and  appropriate
adjustments to all relevant computer codes and similar uncertainties.

                                                        LEASE


         THIS LEASE  AGREEMENT (this "Lease") is entered into as of February 26,
1999,  between  W9/TIB  REAL  ESTATE  LIMITED  PARTNERSHIP,  a Delaware  limited
partnership ("Landlord"),  and KRONOS INCORPORATED,  a Massachusetts corporation
("Tenant").

         1. Lease Grant. Subject to the terms of this Lease,  Landlord leases to

including the office building located thereon  containing  approximately  82,228
rentable square feet (the "Premises"), as shown on the site plan attached hereto

referred  to as the  "Building").  The  legal  description  of the  Premises  is
attached hereto as Exhibit B.

         2. Term.  The term of this Lease  shall  commence on the earlier of (i)

Date"), and expiring on the last day of the month in which the thirteenth (13th)
anniversary of the Commencement Date occurs (the "Term",  which definition shall
include all renewals of the initial Term).  If the Premises are not delivered to

         The term  "Lease  Year"  shall  mean any period of twelve  (12)  months
commencing  on  the  first  day of the  first  full  month  of the  Term  or any
anniversary of such date or, if fewer than twelve (12) months remain in the Term
after any such anniversary  period,  commencing on such anniversary date through
the last day of the Term.

                  (b)......Payment.  Tenant shall  timely pay to Landlord  Basic
Rent and all  additional  sums to be paid by Tenant to Landlord under this Lease
(collectively,  the "Rent"),  without  notice,  deduction or set off,  except as
otherwise  provided herein, at Landlord's  address provided for in this Lease or
as otherwise  specified by Landlord.  Basic Rent,  adjusted as herein  provided,
shall be payable monthly in advance,  and shall be accompanied by all applicable
state and local sales or use taxes. Basic Rent shall be payable on the first day
of each month beginning on the first day of the first full calendar month of the
Term.  The monthly Basic Rent for any partial month at the beginning of the Term
shall equal the product of 1/365 of the annual  Basic Rent in effect  during the
partial  month and the  number of days in the  partial  month from and after the
Commencement Date, and shall be due on the Commencement Date.

                  (c)......Operating Costs.

                           (1)......Tenant  shall pay, as "Additional Rent", the
         Operating  Costs  (defined  below).  Landlord  may  make a  good  faith
         estimate of the  Additional  Rent to be due by Tenant for any  calendar
         year or part thereof during the Term, and Tenant shall pay to Landlord,
         on the  Commencement  Date and on the first day of each calendar  month
         thereafter,  an amount equal to the estimated  Additional Rent for such
         calendar year or part thereof  divided by the number of months therein.
         From time to time,  but not more often  than  twice in any twelve  (12)
         month period, Landlord may estimate and re-estimate the Additional Rent
         to be due by  Tenant  and  deliver  a  detailed  line  item copy of the
         estimate or re-estimate to Tenant. Thereafter, the monthly installments
         of Additional Rent payable by Tenant shall be appropriately adjusted in
         accordance  with the  estimations  so that,  by the end of the calendar
         year in question,  Tenant shall have paid all of the Additional Rent as
         estimated by Landlord. Any amounts paid based on such an estimate shall
         be subject to adjustment as herein provided when actual Operating Costs
         are available for each calendar year.

                           (2)......The  term  "Operating  Costs" shall mean all
         expenses and disbursements (subject to the limitations set forth below)
         that Landlord incurs in connection with the ownership,  operation,  and
         maintenance  of the Premises,  determined in accordance  with generally
         accepted   accounting   principles   ("GAAP")   consistently   applied,
         including,  but not  limited  to, the  following  costs:  (A) wages and
         salaries  (including  management fees) of all employees  engaged in the

         used in the operation,  maintenance,  repair, replacement, and security
         of the Premises; (C) costs for improvements made to the Premises which,
         if capital in nature,  shall be amortized over the useful economic life
         of such  improvements  as  determined  by  Landlord  in its  reasonable
         discretion;  (D) cost of all  utilities,  except the cost of  utilities
         paid  directly by Tenant or  reimbursable  to Landlord by Tenant  other
         than  pursuant  to a  provision  similar  to this  Section  3.(c);  (E)
         insurance expenses; (F) repairs,  replacements, and general maintenance
         of  the  Premises;  and  (G)  service  or  maintenance  contracts  with
         independent  contractors  for  the  operation,   maintenance,   repair,
         replacement,   or  security  of  the   Premises   (including,   without
         limitation, alarm service, window cleaning, and elevator maintenance).

                  Operating  Costs  shall  not  include  costs  for (i)  repair,
         replacements  and general  maintenance paid by proceeds of insurance or
         by Tenant or other third parties; (ii) interest,  amortization or other
         payments  on  loans  to  Landlord;  (iii)  depreciation;  (iv)  leasing
         commissions;  (v) legal  expenses for  services,  other than those that
         benefit Tenant (e.g., tax disputes);  (vi) Taxes (defined below); (vii)
         federal  income taxes  imposed on or measured by the income of Landlord
         from the operation of the  Premises;  (viii) any cost or expense to the
         extent to which Landlord is paid or reimbursed (other than as a payment
         for Operating  Costs),  including but not  necessarily  limited to, (1)
         work or service  performed  for any tenant  (including  Tenant) at such
         tenant's costs,  (2) the cost of any item for which Landlord is paid or
         reimbursed by insurance  warranties,  service  contracts,  condemnation
         proceeds or otherwise,  (3) charges  (including  applicable  taxes) for
         electricity,  water and other  utilities for which Landlord is entitled
         to  reimbursement  pursuant to other  provisions of this Lease, and (4)
         the cost of any HVAC,  janitorial or other services provided to tenants
         on an extra-cost  basis after regular  business hours as defined in the
         Lease;  (ix) the cost of  correcting  initial  defects  in the  design,
         construction or equipment of the Building;  (x) salaries and bonuses of
         officers  and  executives  of  Landlord;  (xi)  any  cost  included  in
         Operating  Costs  representing  an  amount  paid  to  a  person,  firm,
         corporation  or other entity  related to Landlord which is in excess of
         the amount  which would have been paid on an arms  length  basis in the
         absence of such relationship;  (xii) any capital cost necessary to cure
         any  violation of any law,  ordinance or  regulation  applicable to the
         Building  existing  as of the  Commencement  Date or to  remediate  any
         environmental condition (existing as of the date of the Lease) provided
         Tenant in no way  exacerbates  any such  condition;  (xiii) the cost of
         acquiring  sculptures,  paintings and other objects of art in excess of
         $2,000 per item; and (xiv) the cost of advertising or promotion for the
         Building.



<PAGE>


                           (3)......Tenant  shall  also pay the  Taxes  for each
         year and partial  year falling  within the Term,  in the same manner as
         provided  above for  Additional  Rent with regard to  Operating  Costs.
         "Taxes" shall mean taxes, assessments, and governmental charges whether
         federal,  state,  county or  municipal,  and whether  they be by taxing
         districts or authorities  presently  taxing or by others,  subsequently
         created or otherwise,  and any other taxes and assessments attributable
         to the Building (or its operation),  excluding,  however, penalties and
         interest  thereon and federal and state taxes on income (if the present
         method of taxation  changes so that in lieu of the whole or any part of
         any Taxes,  there is levied on Landlord a capital  tax  directly on the
         rents  received  therefrom or a franchise  tax,  assessment,  or charge
         based, in whole or in part, upon such rents for the Building,  then all
         such  taxes,  assessments,  or charges,  or the part  thereof so based,
         shall be deemed to be included  within the term  "Taxes"  for  purposes
         hereof).  Tenant  shall,  at its sole cost and  expense  and upon prior
         written notice to Landlord,  have the right to seek an abatement of the
         Taxes provided that Tenant shall promptly  provide Landlord with copies
         of all papers filed with various authorities in connection with seeking
         such an  abatement  and with copies of all papers  received  from other
         parties  relating to any such abatement.  Taxes shall include the costs
         of  consultants  retained  in an  effort  to lower  taxes and all costs
         incurred  in  disputing  any  taxes  or in  seeking  to  lower  the tax
         valuation of the Building.  The following  items shall be excluded from
         Taxes:  (A) inheritance  taxes; (B) gift taxes; (C) transfer taxes; (D)
         franchise  taxes; (E) excise taxes; (F) income taxes; (G) profit taxes;
         and (H) late payment  charges and penalties  provided  Tenant is not in
         default of any of its payment obligations under this Lease.  Subject to
         the provisions of the next succeeding sentence, any real estate related
         betterment assessments shall be payable over the longest period of time
         permitted by law. If Landlord elects to pay any such assessments over a
         shorter period of time, Tenant shall only be required to pay during any
         given  period of time that portion of any given  assessment  that would
         have  been  required  to be paid  during  such  period  of time if such
         assessment  had been paid over the longest  period of time permitted by
         law.

                           (4)......By April 1 of each calendar year, or as soon
         thereafter as practicable, Landlord shall furnish to Tenant a statement
         of  Operating  Costs for the  previous  year,  adjusted  as provided in
         Section  3.(c)(6),  and  of  the  Taxes  for  the  previous  year  (the
         "Operating  Costs and Tax  Statement").  If the Operating Costs and Tax
         Statement  reveals that Tenant paid more for  Operating  Costs than the
         actual amount for the year for which such  statement  was prepared,  or
         more than its actual share of Taxes for such year,  then Landlord shall
         promptly  credit or  reimburse  Tenant for such  excess;  likewise,  if
         Tenant  paid less than the actual  Additional  Rent or Taxes due,  then
         Tenant shall promptly pay Landlord such  deficiency  within thirty (30)
         days after receiving written notice from Landlord of the amount of such
         deficiency.  Any such  Operating  Costs and Tax Statement  furnished by
         Landlord  shall be binding and  conclusive  upon Tenant  unless  Tenant
         shall notify  Landlord  that Tenant  disputes the  correctness  of such
         Operating Costs and Tax Statement  within one hundred eighty (180) days
         after the  submission  thereof by  Landlord.  If Tenant  disputes  such
         Operating  Cost and Tax  Statement as  aforesaid,  and Tenant is not in
         default of its monetary obligations under this Lease, Tenant shall have
         the right to audit  Landlord's  books used to determine  said Operating
         Cost and Tax  Statement  within  one  hundred  eighty  (180) days after
         submission  thereof  by  Landlord,  which  right  Tenant  agrees not to
         exercise more than once annually. Access to said Operating Cost and Tax
         Statement  books shall be provided  within thirty (30) days of Tenant's
         request.  Any information obtained by Tenant pursuant to the provisions
         of this Section 3(d)(4) shall be treated as  confidential.  If any such
         audit discloses Tenant paid in excess of Tenant's  proportionate  share
         of Operating Costs or Tax Escalation, Landlord shall promptly reimburse
         such excess to Tenant  within  thirty (30) days after  Tenant's  demand
         therefor.  Landlord  shall  maintain  its books used to  determine  the
         Operating Cost and Tax Statement in a manner  consistent with reputable
         professional  standards  used  to  maintain  the  books  of  comparable
         properties.



<PAGE>


         4. Delinquent Payment;  Handling Charges. All payments past due by five
(5) days beyond the due date  required of Tenant  hereunder  shall bear interest
from the fifth (5th) day beyond the date due until paid at the lesser of 18% per
annum (the "Interest Rate") or the maximum lawful rate of interest. In no event,
however,  shall the charges  permitted under this Section 4 or elsewhere in this
Lease,  to the extent they are considered to be interest  under law,  exceed the
maximum lawful rate of interest.

         5.  Security  Deposit.  Contemporaneously  with the  execution  of this
Lease, Tenant shall pay to Landlord $160,000.00 (the "Security Deposit"),  which
shall be held by  Landlord to secure  Tenant's  performance  of its  obligations
under this Lease.  The Security  Deposit is not an advance  payment of Rent or a
measure or limit of  Landlord's  damages  upon an Event of Default  (defined  in
Section 16).  Landlord may, from time to time and without prejudice to any other
remedy,  use all or a part of the  Security  Deposit to perform  any  obligation
Tenant  fails  to  perform  hereunder.  Following  any such  application  of the
Security  Deposit,  Tenant shall pay to Landlord on demand the amount so applied
in order to restore the Security Deposit to its original  amount.  Provided that
Tenant has performed all of its obligations  hereunder,  Landlord shall,  within
thirty  (30) days  after the Term  ends,  return to Tenant  the  portion  of the
Security  Deposit  which was not applied to satisfy  Tenant's  obligations.  The
Security  deposit may be commingled  with other funds,  and no interest shall be
paid  thereon.  If  Landlord  transfers  its  interest in the  Premises  and the
transferee  assumes  Landlord's  obligations under this Lease, then Landlord may
assign the Security Deposit to the transferee and Landlord thereafter shall have
no further liability for the return of the Security Deposit.



<PAGE>


         In lieu of a cash Security Deposit,  simultaneously  with the execution
and delivery of this Lease,  Tenant may deliver to Landlord an  irrevocable  and
unconditional standby letter of credit made payable to Landlord,  its successors
and assigns,  in the sum of $160,000.00 (the "Letter of Credit"),  substantially
in the form of the sample  letter of credit  attached  hereto as Exhibit F or in
such other form as is reasonably acceptable to Landlord,  which shall secure the
performance by Tenant of all  obligations on the part of Tenant  hereunder.  The
issuer of the Letter of Credit  shall be a banking  institution  with at least a
rating of A and otherwise reasonably  acceptable to Landlord.  Although Landlord
shall  only  have the  right to draw  under  the  Letter  of Credit as set forth
herein,  under  the  terms  of the  Letter  of  Credit,  the sole  condition  to
Landlord's  draw upon the Letter of Credit  shall be  presentment  to the issuer
thereof, prior to or on the expiration date, of a demand for payment. The Letter
of Credit shall be self-renewing from year to year during the Term of this Lease
so as to expire no earlier than thirty (30) days following the Lease  expiration
date and shall contain such other  customary  terms as Landlord  requires in its
reasonable discretion.  It is agreed: (i) that the Letter of Credit may be drawn
upon to cure any Event of Default that may exist, without prejudice to any other
remedy  or  remedies  which  Landlord  may  have on  account  thereof,  and upon
Landlord's demand,  Tenant shall reimburse the issuer for the amount so drawn so
that the Letter of Credit will be restored to its original amount;  (ii) subject
to the  provisions of clause (iv) below,  that the Letter of Credit may be drawn
upon if the Letter of Credit has not been extended or renewed without  amendment
at least forty-five (45) days prior to any then-current expiration date thereof;
(iii) that if the rating of the issuer of the Letter of Credit at any time drops
below A, then, within sixty (60) days of Landlord's demand, Tenant shall replace
the  Letter  of Credit  with  another  Letter  of  Credit  in a form  reasonably
acceptable  to  Landlord  and with an issuer  with a rating of at least an A and
otherwise reasonably  acceptable to Landlord;  Landlord may draw on the existing
Letter of Credit if, after  Landlord  requests that Tenant replace the Letter of
Credit as aforesaid, Landlord is not provided with a substitute Letter of Credit
in a form,  and from an issuer,  satisfactory  to Landlord as provided  above at
least fifteen (15) days prior to the then-current  expiration date of the Letter
of Credit; (iv) if at any time, but in any event, at least sixty (60) days prior
to the expiration of the Letter of Credit, Tenant may seek Landlord's consent to
switch  issuers of the Letter of Credit  provided the  prospective  issuer has a
rating of at least an A and is otherwise  reasonably  acceptable to Landlord and
the new  form of  Letter  of  Credit  satisfies  the  requirements  of  Landlord
hereunder and is otherwise reasonably acceptable to Landlord;  Landlord may draw
on the existing Letter of Credit if, after Tenant requests Landlord's consent to
switch issuers as aforesaid,  Landlord is not provided with a substitute  Letter
of Credit in a form,  and from an issuer,  satisfactory  to Landlord in its sole
and absolute  discretion at least forty-five (45) days prior to the then-current
expiration  date of the  Letter of  Credit;  (v) that  should  the  Premises  be
conveyed  by  Landlord,  the Letter of Credit or any  portion  thereof  shall be
assigned to Landlord's grantee, and if the same be assigned as aforesaid, Tenant
hereby  releases  Landlord from any and all liability with respect to the Letter
of Credit  and its  application  or return,  and  Tenant  agrees to look to such
grantee for such application or return, provided such grantee assumes Landlord's
obligations  under  this Lease  (including  this  Section  5); and (vi) that the
Letter of Credit  shall be  returned to Tenant upon the later of (a) thirty (30)
days after the  expiration of the Term or any renewal or extension  thereof,  or
(b) the date Tenant has vacated the Premises and surrendered  possession thereof
to Landlord at the  expiration of the Term or any extension  thereof as provided
herein and has paid Landlord all sums due and owing under this Lease.

         If Tenant  initially  provides  Landlord with a cash Security  Deposit,
Tenant  may  replace  such  cash  Security  Deposit  with a Letter  of Credit in
accordance  with the  provisions of the  preceding  paragraph.  Upon  Landlord's
receipt  of a Letter  of Credit  satisfying  the  terms  and  conditions  of the
preceding paragraph, Landlord shall promptly return the cash Security Deposit to
Tenant.

         For the  purposes  of this  Section  5, a rating  of at least A (or its
equivalent)  shall  mean  that  such  issuer  has a rating of at least A (or its
equivalent)  from two (2) of the  following  four  (4)  rating  agencies:  Fitch
Investors Service,  Moody's Investor Service,  Standard & Poor's Corporation and
Duff & Phelps.

         6. Landlord's Obligations.



<PAGE>


                  (a)......Services.   Landlord  shall  furnish  to  Tenant  the
following  services (the cost of which  services  shall be considered  Operating
Costs):  (1) hot and cold water at bathroom  sinks  provided  for general use of
tenants of the  Building;  (2)  heated  and  refrigerated  air  conditioning  as
appropriate,  at such  temperatures  and in such  amounts  as are  standard  for
comparable  buildings in the vicinity of the Building;  (3)  janitorial  service
(which janitorial  service shall include service to the interior and exterior of
the  Building  and the  Premises  and shall  include  the  services  customarily
provided  to  comparable   properties  by  reputable   professional   management
companies, including, without limitation,  maintenance,  repairs and replacement
of (u) the  parking  area  associated  with  the  Building  and  located  on the
Premises,  (v) all  grass,  shrubbery  and  other  landscape  treatments  on the
Premises,  (w) the exterior of the Building (including painting),  (x) sprinkler
systems and sewage lines, and (y) any other  maintenance,  repair or replacement
items normally associated with the foregoing) to the Premises on weekdays, other
than the  holidays  enumerated  on  Exhibit  I  attached  hereto  (collectively,
"Building  Holidays"),  for  Building-standard  installations  and  such  window
washing as may from time to time be reasonably  required but not less than twice
a year;  (4)  elevators  for ingress  and egress to the floors of the  Building,
provided that Landlord may  reasonably  limit the number of operating  elevators
during non-business hours and holidays; and (5) electrical current during normal
business hours for equipment that does not require more than 110 volts and whose
electrical energy  consumption does not exceed normal office usage. While Tenant
is the sole occupant of the Building,  Tenant may, with Landlord's prior written
consent  (which  consent  shall  not  be  unreasonably   withheld  or  delayed),
substitute at Tenant's expense any of the providers of the services described in
this  Section  6.(a) with  reputable,  licensed  third party  service  providers
located in the area in which the Building is located; provided,  however, Tenant
shall  provide  Landlord  with  copies of all  contracts  with any such  service
provider  and  said  contracts  shall  be  in  form  and  substance   reasonably
satisfactory to Landlord. If, in accordance with the provisions of the preceding
sentence,  Tenant engages (at its own cost) providers for all of the services to
be provided by Landlord under this Section 6.(a), the management fee included in
Operating  Costs shall be reduced to the greater of (i)  $1,300.00  per month or
(ii) one and  one-quarter  percent  (1 1/4%) of the gross  revenues  derived  by
Landlord  from the  Premises.  If Tenant  engages  providers of the services set
forth in this Section 6.(a) as aforesaid and any such services are provided,  in
Landlord's   reasonable   discretion,   at  an  unsatisfactory  level  as  would
customarily  be provided  to  comparable  buildings,  Landlord  may,  upon prior
written notice to Tenant,  elect to provide such services and the management fee
shall no longer be reduced.  If Landlord is providing  the services set forth in
this Section 6.(a) and Tenant  desires any of the services  specified in Section
6.(a)(2): (A) at any time other than between 8:00 a.m. and 6:00 p.m. on weekdays
(excluding Building Holidays), or (B) on Saturday,  Sunday or Building Holidays,
then such  services  shall be supplied  to Tenant  upon the  written  request of
Tenant delivered to Landlord before 3:00 p.m. on the business day preceding such
extra usage,  and Tenant shall pay to Landlord the cost of such services  within
ten (10) days after  Landlord has delivered to Tenant an invoice  therefor.  The
costs incurred by Landlord in providing  after-hour HVAC service to Tenant shall
include costs for electricity,  water, sewage, water treatment, labor, metering,
filtering,  and maintenance  reasonably  allocated by Landlord to providing such
service.

         Landlord  and  Tenant  hereby  acknowledge  and agree  that,  as of the
Commencement  Date,  Tenant shall engage  providers of the services set forth in
this  Section  6.(a).  However,  upon sixty (60) days  prior  written  notice to
Landlord, Tenant may elect to have Landlord provide such services.



<PAGE>


         If,  during  the last  two (2)  years  of the  Term  (inclusive  of the
five-year extension if Tenant elects to exercise the same in accordance with the
provisions of Exhibit G) and during a time when Tenant is engaging  providers of
the services set forth in this Section  6.(a),  Tenant  elects to make a capital
improvement to the Base Building (as hereinafter  defined)  because that portion
of the Base Building fails to operate (as opposed to operates less efficiently),
Landlord agrees to pay the unamortized  cost of any such capital  improvement on
the following terms and conditions  provided such failure is not a result of any
act, omission,  fault,  negligence or neglect of Tenant, its agents,  employees,
invitees or contractors: (i) Landlord and Tenant agree in writing on the cost of
any such  capital  improvement  and the useful life over which any such  capital
improvement  shall be amortized  prior to the  installation  of any such capital
improvement  (ii) to the extent  capital  improvements  are  devoted to Building
systems, the Building systems shall not be in excess of standard building design
for comparable  buildings in the 495 North market;  and (iii) Landlord agrees to
pay the unamortized cost of any such capital improvement as previously agreed to
in  writing  by the  parties  within  sixty  (60)  days  after  the later of the
expiration  of  this  Lease  or the  date  Tenant  surrenders  the  Premises  in
accordance  with this Lease provided  Tenant is not in default  hereunder,  this
Lease  does not  terminate  prior to the stated  expiration  date and Tenant has
maintained  and repaired any such capital  improvement  in  accordance  with the
provisions of this Lease.

         For the  purposes of this  Lease,  the "Base  Building"  shall mean the
roof,  foundation,  structural columns and Building systems to the extent any of
the foregoing have not been altered or improved by Tenant in any manner.

                  (b)......Landlord's  Maintenance  Obligations.  This  Lease is
intended to be a net lease; accordingly,  Landlord's maintenance obligations are
limited to the repair,  maintenance  and  replacement of the Building's roof and
the repair, maintenance and replacement of the foundation and structural members
of  exterior  walls  (the  "Building's   Structure");   Landlord  shall  not  be
responsible  for (1) any such work until  Tenant  notifies  Landlord of the need
therefor in writing, (2) for alterations to the Building's Structure required by
applicable law because of Tenant's use of the Premises (which  alterations shall
be Tenant's responsibility),  (3) any such work caused by Tenant's negligence or
its  failure  to comply  with the  provisions  of this  Lease,  or (4) any costs
incurred by Landlord in connection  with the repair and maintenance of the roof,
which repair and  maintenance  costs shall be considered  an Operating  Cost and
paid by Tenant in accordance with Section 3 above. The Building's Structure does
not include skylights,  windows, glass or plate glass, doors, special fronts, or
office entries,  all which shall be maintained by Tenant.  Landlord's  liability
for any  defects,  repairs,  replacements  or  maintenance  for  which  Landlord
specifically is responsible for under this Lease shall be limited to the cost of
performing the work.

                  (c)......Excess Utility Use. Landlord shall not be required to
furnish  electrical current for equipment that requires more than the electrical
capacity  currently  provided in the  Building  (the "Base  Building  Electrical
Capacity").  If Tenant's  requirements for or consumption of electricity  exceed
the Base Building Electrical Capacity, Landlord shall, at Tenant's expense, make
reasonable efforts to supply such service through the then-existing  feeders and
risers  serving the Building,  and Tenant shall pay to Landlord the cost of such
service  within ten (10) days after  Landlord has delivered to Tenant an invoice
therefor.  Landlord may determine the amount of such additional  consumption and
potential  consumption by any verifiable  method,  including  installation  of a
separate meter in the Premises installed,  maintained,  and read by Landlord, at
Tenant's expense.  Tenant shall not install any electrical  equipment  requiring
special  wiring or requiring  voltage in excess of the Base Building  Electrical
Capacity unless  approved in advance by Landlord.  The use of electricity in the
Premises  shall not exceed the  capacity  of  existing  feeders and risers to or
wiring in the Building.  Any risers or wiring  required to meet Tenant's  excess
electrical  requirements  shall, upon Tenant's written request,  be installed by
Landlord,  at Tenant's cost, if, in Landlord's judgment,  the same are necessary
and shall not cause permanent  damage to the Building or the Premises,  cause or
create a dangerous  or hazardous  condition,  entail  excessive or  unreasonable
alterations, repairs, or expenses, or interfere with or disturb other tenants of
the Building.  If Tenant uses machines or equipment in the Building which affect
the temperature otherwise maintained by the air conditioning system or otherwise
overload any utility,  Landlord may install  supplemental air conditioning units
or other supplemental equipment in the Building, and the cost thereof, including
the cost of  installation,  operation,  use, and  maintenance,  shall be paid by
Tenant to Landlord  within ten (10) days after  Landlord has delivered to Tenant
an invoice therefor.

                  (d)......Restoration  of Services;  Abatement.  Landlord shall
use  reasonable  efforts to restore  any  service  required  of it that  becomes
unavailable;  however,  such unavailability shall not render Landlord liable for
any damages caused thereby, be a constructive  eviction of Tenant,  constitute a
breach of any implied  warranty,  or,  except as provided in the next  sentence,
entitle Tenant to any abatement of Tenant's obligations hereunder.  If, however,
Tenant is prevented  from using the Premises for ten (10)  consecutive  business
days because of the  unavailability  of any such service,  then Tenant shall, as
its  exclusive  remedy be entitled to a  reasonable  abatement  of Rent for each
consecutive  day (after  such ten (10) day period)  that Tenant is so  prevented
from using the Premises.

                  (e)......Taxes.  Provided  Tenant is not in  default of any of
its monetary obligations under this Lease,  Landlord shall pay promptly when due
to the taxing authority having jurisdiction all taxes, rates, duties, levies and
assessments whatsoever,  whether municipal, state, Federal or otherwise, levied,
imposed or assessed  against the Building or upon Landlord in respect thereof or
from time to time  levied,  imposed or assessed  in the future in lieu  thereof,
including  those levied,  imposed or assessed for  education,  schools and local
improvements.

                  (f)......Landlord's  Insurance.  Landlord shall carry 
 throughout  the Term of this Lease fire and extended  coverage
                           --------------------- 
insurance on the Building for the full replacement value.

         7.       Improvements; Alterations; Repairs; Maintenance.



<PAGE>


                  (a)......Improvements;   Alterations.   Improvements   to  the
Premises  shall be installed at Tenant's  expense only in accordance  with plans
and  specifications  which have been  previously  submitted  to and  approved in
writing by Landlord.  No alterations or physical additions in or to the Premises
may be made  without  Landlord's  prior  written  consent,  which  shall  not be
unreasonably withheld or delayed;  however, Landlord may withhold its consent to
any  alteration  or addition that would affect the  Building's  structure or its
HVAC,  plumbing,   electrical,   or  mechanical  systems.   Notwithstanding  the
foregoing,  Tenant  may  from  time  to  time  make  alterations,  additions  or
improvements  to the  Premises,  without  the  consent of  Landlord  and without
Landlord's  approval of plans,  provided:  (i) the cost thereof shall not exceed
Fifty  Thousand  Dollars  ($50,000.00)  in  the  aggregate  in  any  consecutive
twelve-month   period;   (ii)  Tenant  shall,   prior  to  commencing  any  such
alterations,  additions  and/or  improvements  in  the  Premises  in  connection
therewith,  furnish Landlord with a complete set of plans and specifications for
any such  alterations,  additions and/or  improvements;  (iii) such alterations,
additions  and/or  improvements  shall not involve or affect the exterior or the
structure  of the  Building  or any of the  mechanical,  electrical  or plumbing
systems of the Building;  and (iv) Tenant shall comply with all  requirements of
this Lease with respect to such alterations, additions and/or improvements other
than obtaining the prior approval of Landlord. Tenant shall not paint or install
lighting or decorations,  signs, window or door lettering,  or advertising media
of any type on or about the Premises  which might affect the  appearance  of the
exterior of the  Building or any other  portion of the  Premises  other than the
interior of the Building  without the prior written  consent of Landlord,  which
shall not be unreasonably  withheld or delayed;  however,  Landlord may withhold
its  consent  to any such  painting  or  installation  which  would  affect  the
appearance  of the  exterior  of the  Building  or of any  common  areas  of the
Building.  All  alterations,  additions,  or  improvements  made in or upon  the
Premises  shall be  removed by Tenant  prior to the end of the Term (and  Tenant
shall repair all damage caused  thereby) if Landlord  conditioned its consent to
the initial installation of any such alterations, additions or improvements upon
such removal; otherwise, in the absence of such a removal condition with respect
to each and every  alteration,  addition or improvement,  all such  alterations,
additions or improvements  (excluding  moveable  partitions) shall remain on the
Premises at the end of the Term without compensation to Tenant. All alterations,
additions,  and  improvements  shall  be  constructed,  maintained,  and used by
Tenant,  at its risk and  expense,  in  accordance  with  all  Laws;  Landlord's
approval of the plans and specifications  therefor shall not be a representation
by Landlord that such alterations,  additions,  or improvements  comply with any
Law.



<PAGE>


                  (b)......Repairs;   Maintenance.  Tenant  shall  maintain  the
Premises in a clean safe, and operable  condition  consistent with the operation
of a first class  office  building,  and shall not permit or allow to remain any
waste or damage  to any  portion  of the  Premises.  If Tenant  elects to engage
providers for all services in accordance with Section 6.(a) above,  Tenant shall
enter  into  preventative   maintenance/service   contract(s)  with  maintenance
contractor(s) approved by Landlord for servicing the landscaping of the Premises
and all air conditioning, heating and ventilating equipment, elevators and other
equipment   located   within  or  serving   the   Premises.   All   preventative
maintenance/service   contracts  shall  be  in  form  and  substance  reasonably
satisfactory to Landlord and shall provide that the maintenance contractor shall
provide  Landlord with  quarterly  reports  respecting  the  maintenance  of the
subject  equipment.  Tenant  shall  provide  Landlord  with  copies  of all such
preventative maintenance/service contracts maintained by Tenant. Irrespective of
whether  or not  Tenant  elects  not to engage  providers  for all  services  in
accordance with Section 6.(a) above, Tenant shall repair or replace,  subject to
Landlord's  reasonable  direction and  supervision,  any  improvement  or system
installed by Tenant within the Premises and any damage to the Building caused by
Tenant,  Tenant's  transferees,  or their  respective  agents,  contractors,  or
invitees.  If Tenant fails to make such repairs or  replacements  within  thirty
(30) days (or such  shorter  period of time  required to prevent any damage from
occurring to the Premises)  after the  occurrence of such damage,  then Landlord
may make the same at Tenant's cost.

                  (c)......Performance  of  Work.  All  work  described  in this
Section  7  shall  be  performed  only  by  Landlord  or  by   contractors   and
subcontractors  reasonably  approved in writing by Landlord  and Tenant.  Tenant
shall cause all contractors and subcontractors to procure and maintain insurance
coverage  naming  Landlord as an additional  insured against such risks, in such
amounts,  and with such companies as Landlord may reasonably  require.  All such
work  shall  be  performed  in  accordance  with  all  Laws  and in a  good  and
workmanlike  manner so as not to  damage  the  Premises,  the  Building,  or the
components thereof.

         Tenant shall  provide the names,  addresses and copies of contracts for
all contractors, and upon completion of any work shall promptly furnish Landlord
with full and final waivers of lien  covering all labors and materials  included
in the work in question.

                  (d)......Mechanic's   Liens.   Tenant  shall  not  permit  any
mechanic's  liens to be filed  against the Premises or the Building for any work
performed,  materials furnished,  or obligation incurred by or at the request of
Tenant. If such a lien is filed,  then Tenant shall,  within ten (10) days after
Landlord has delivered  notice of the filing  thereof to Tenant,  either pay the
amount of the lien or  diligently  contest  such lien and  deliver to Landlord a
bond or other security reasonably  satisfactory to Landlord.  If Tenant fails to
timely take either such action,  then  Landlord may pay the lien claim,  and any
amounts so paid,  including  expenses and  interest,  shall be paid by Tenant to
Landlord within ten days after Landlord has invoiced Tenant therefor.

                  (e)......Utilities. Tenant shall obtain and pay for all water,
gas, electricity,  heat, telephone, sewer, sprinkler charges and other utilities
and  services  used  at  the  Premises,  together  with  all  taxes,  penalties,
surcharges,  and maintenance charges pertaining  thereto.  Landlord shall not be
liable for any interruption or failure of utility service to the Premises unless
caused by  Landlord's  gross  negligence.  To the  extent  Tenant is not  billed
directly  for any such  utilities,  any  amounts  payable  by Tenant  under this
Section  shall be due within ten (10) days after  Landlord has  invoiced  Tenant
therefor.

                  (f)......Floor  Load;  Heavy  Machinery.  (i) Tenant shall not
place a load upon any floor in the Building  exceeding the floor load per square
foot of area which such floor was  designed to carry or which is allowed by law.
Landlord reserves the right to prescribe the weight and position of all business
machines and mechanical equipment,  including safes, which shall be placed so as
to distribute the weight.  Business  machines and mechanical  equipment shall be
placed and maintained by Tenant at Tenant's expense in settings  sufficient,  in
Landlord's  judgment,  to absorb and  prevent  vibration,  noise and  annoyance.
Tenant shall not move any safe,  heavy machinery  and/or heavy equipment into or
out of the Building without Landlord's prior consent,  which consent may include
a  requirement  to provide  insurance,  naming  Landlord as an insured,  in such
amounts as Landlord may deem reasonable.



<PAGE>


                           (ii).....If such safe, machinery,  equipment, 
freight,  bulky matter or fixtures requires special handling,
Tenant agrees that all work in connection therewith shall comply with applicable
laws and  regulations.  Any such moving  shall be at the sole risk and hazard of
Tenant, and Tenant will exonerate,  indemnify and save Landlord harmless against
and from any  liability,  loss,  injury,  claim or suit  resulting  directly  or
indirectly from such moving.

         8. Use. Tenant shall continuously  occupy and use the Premises only for
general  office,  research  and  development,  manufacturing,  training,  sales,
service and engineering use (the  "Permitted  Use"),  provided the Permitted Use
complies with all  applicable  laws,  and shall comply with all Laws relating to
the use, condition, access to, and occupancy of the Premises. The Premises shall
not be used  for any use  which  is  disreputable,  creates  extraordinary  fire
hazards,  or results in an  increased  rate of insurance  on the  Premises,  the
Building or its  contents,  or for the  storage of any  hazardous  materials  or
substances.  If,  because of a Tenant Party's acts, the rate of insurance on the
Building or its contents increases, then such acts shall be an Event of Default,
Tenant  shall  pay to  Landlord  the  amount of such  increase  on  demand,  and
acceptance  of such  payment  shall not waive any of  Landlord's  other  rights.
Tenant shall  conduct its business and control each other Tenant Party so as not
to create any nuisance or unreasonably interfere with Landlord in its management
of the Building.

         9.       Assignment and Subletting.



<PAGE>


                  (a)......Transfers;  Consent.  Tenant  shall not,  without the
prior written consent of Landlord, (1) assign,  transfer, or encumber this Lease
or any estate or interest  herein,  whether directly or by operation of law, (2)
permit any other entity to become Tenant hereunder by merger, consolidation,  or
other reorganization,  (3) if Tenant is an entity other than a corporation whose
stock is publicly traded, permit the transfer of an ownership interest in Tenant
so as to result in a change in the  current  control of  Tenant,  (4) sublet any
portion of the Premises,  (5) grant any license,  concession,  or other right of
occupancy of any portion of the Premises,  or (6) permit the use of the Premises
by any parties other than Tenant (any of the events  listed in Section  9.(a)(1)
through 9.(a)(6) being a "Transfer"). If Tenant requests Landlord's consent to a
Transfer,  then Tenant shall provide Landlord with a written  description of all
terms  and  conditions  of  the  proposed  Transfer,   copies  of  the  proposed
documentation, and the following information about the proposed transferee: name
and address; reasonably satisfactory information about its business and business
history; its proposed use of the Premises;  banking, financial, and other credit
information;  and general references  sufficient to enable Landlord to determine
the proposed  transferee's  creditworthiness  and character.  Landlord shall not
unreasonably  withhold or delay its consent to any  assignment  or subletting of
the Premises, provided that the proposed transferee (A) is creditworthy, (B) has
a good reputation in the business  community,  and (C) is not a person or entity
with whom  Landlord is  negotiating  to lease space in an  Affiliated  Building;
otherwise,   Landlord  may   withhold  its  consent  in  its  sole   discretion.
Concurrently  with  Tenant's  notice of any  request  for consent to a Transfer,
Tenant shall pay to Landlord a fee of $500.00 to defray  Landlord's  expenses in
reviewing  such request,  and Tenant shall also reimburse  Landlord  immediately
upon request for its  reasonable  attorneys'  fees incurred in  connection  with
considering  any request for  consent to a Transfer.  If Landlord  consents to a
proposed  Transfer,  then the proposed  transferee  shall  deliver to Landlord a
written agreement whereby it expressly assumes Tenant's  obligations  hereunder;
however,  any  transferee of less than all of the space in the Premises shall be
liable only for obligations under this Lease that are properly  allocable to the
space subject to the Transfer for the period of the Transfer.  No Transfer shall
release Tenant from its obligations  under this Lease, but rather Tenant and its
transferee shall be jointly and severally liable therefor. Landlord's consent to
any Transfer shall not waive Landlord's  rights as to any subsequent  Transfers.
If an Event of Default occurs while the Premises or any part thereof are subject
to a Transfer,  then Landlord,  in addition to its other  remedies,  may collect
directly from such  transferee  all rents  becoming due to Tenant and apply such
rents against Rent.  Tenant  authorizes its transferees to make payments of rent
directly to Landlord upon receipt of notice from Landlord to do so. Tenant shall
pay for the cost of any demising walls or other  improvements  necessitated by a
proposed  subletting  or  assignment.  Notwithstanding  any  provisions  of this
Section 9(a) to the contrary,  Tenant may assign or sublet,  without  Landlord's
prior  written  consent,  to any entity  into or with which  Tenant is merged or
consolidated  or to  which  all or  substantially  all of  Tenant's  assets  are
transferred  or to any entity which  controls or is  controlled  by Tenant or is
under common control with Tenant ("Affiliate of Tenant"),  provided that (i) the
assignee  agrees  directly  with  Landlord,   by  written   instrument  in  form
satisfactory to Landlord,  to be bound by all  obligations of Tenant  hereunder,
including,  without  limitation,  the covenant  against further  Transfer,  (ii)
Tenant provides Landlord with notice of and information (reasonably satisfactory
to Landlord)  regarding any such Affiliate of Tenant and such assignment to such
Affiliate of Tenant before the effective date thereof, (iii) Tenant shall remain
fully liable for all obligations of Tenant hereunder,  and (iv) the Affiliate of
Tenant has a net worth equal to or greater  than the greater of (A)  ninety-five
percent  (95%) of Tenant's  net worth as of the date  hereof or (B)  ninety-five
percent (95%) of Tenant's net worth at the time of the Transfer.

                  (b)......Cancellation.  Landlord may,  within thirty (30) days
after  submission  of  Tenant's  written  request for  Landlord's  consent to an
assignment or  subletting  (except for an assignment or sublease to an Affiliate
of Tenant),  cancel this Lease as to the portion of the Premises  proposed to be
sublet or assigned  as of the date the  proposed  Transfer  is to be  effective,
unless,  and  subject  to the  provisions  of the  succeeding  sentence,  Tenant
withdraws  its  request  for  Landlord's  consent  within  ten (10)  days  after
Landlord's  notice to Tenant of  Landlord's  cancellation  of this Lease as to a
portion  of such  Premises.  Tenant  shall only have the right to  withdraw  its
request for Landlord's  consent if it pertains to a sublease of a portion of the
Building or a sublease of the Premises for less than the  remainder of the Term.
If  Landlord  cancels  this Lease as to any  portion of the  Premises  (assuming
Tenant does not withdraw its request as aforesaid),  then this Lease shall cease
for such  portion of the  Premises  and Tenant  shall pay to  Landlord  all Rent
accrued  through the  cancellation  date relating to the portion of the Premises
covered by the proposed Transfer. Thereafter, Landlord may lease such portion of
the Premises to the  prospective  transferee  (or to any other  person)  without
liability to Tenant.



<PAGE>


                  (c)......Additional   Compensation.   Tenant   shall   pay  to
Landlord,  immediately upon receipt thereof,  the excess of (1) all compensation
received by Tenant for a Transfer less the costs  reasonably  incurred by Tenant
with  unaffiliated  third  parties  in  connection  with  such  Transfer  (i.e.,
brokerage  commissions,  tenant  finish  work,  and the like)  over (2) the Rent
allocable to the portion of the Premises covered thereby.

         10.      Insurance; Waivers; Subrogation; Indemnity.

                  (a)......Insurance.  Tenant shall maintain throughout the Term
the following insurance policies:  (1) commercial general liability insurance in
amounts of $5,000,000  per occurrence or such other amounts as Landlord may from
time to time reasonably require,  insuring Tenant,  Landlord,  Landlord's agents
and their respective  affiliates against all liability for injury to or death of
a person or persons or damage to property  arising from the use and occupancy of
the  Premises,  (2) insurance  covering the full value of Tenant's  property and
improvements, and other property (including property of others) in the Premises,
(3)  contractual  liability  insurance  sufficient to cover  Tenant's  indemnity
obligations  hereunder,  (4) worker's compensation  insurance,  and (5) business
interruption  insurance.  Tenant's  insurance shall provide primary  coverage to
Landlord  when any  policy  issued to  Landlord  provides  duplicate  or similar
coverage,  and in  such  circumstance  Landlord's  policy  will be  excess  over
Tenant's policy. Tenant shall furnish to Landlord certificates of such insurance
and such other  evidence  satisfactory  to  Landlord of the  maintenance  of all
insurance  coverages  required  hereunder,  and  Tenant  shall  obtain a written
obligation  on the part of each  insurance  company to notify  Landlord at least
thirty (30) days before  cancellation or a material change of any such insurance
policies. All such insurance policies shall be in form, and issued by companies,
reasonably satisfactory to Landlord.

                  (b)......Waiver  of Negligence;  No Subrogation.  Landlord and
Tenant each  waives any claim it might have  against the other for any injury to
or death of any person or persons or damage to or theft,  destruction,  loss, or
loss of use of any  property  (a  "Loss"),  to the  extent  the same is  insured
against  under any  insurance  policy that covers the  Building,  the  Premises,
Landlord's or Tenant's fixtures, personal property,  leasehold improvements,  or
business,  or, in the case of Tenant's waiver, is required to be insured against
under the terms hereof,  regardless of whether the negligence of the other party
caused such Loss;  however,  Landlord's  waiver shall not include any deductible
amounts on insurance  policies  carried by Landlord.  Each party shall cause its
insurance  carrier to endorse all  applicable  policies  waiving  the  carrier's
rights of recovery under subrogation or otherwise against the other party.

                  (c)......Indemnity.  Subject to Section  10.(b),  Tenant shall
defend, indemnify, and hold harmless Landlord and its representatives and agents
from and against  all claims,  demands,  liabilities,  causes of action,  suits,
judgments,  damages,  and expenses (including  attorneys' fees) arising from (1)
any Loss  arising  from any  occurrence  on the  Premises  (other  than any Loss
arising out of a breach of Tenant's  obligations  under  Section  24.(u),  which
shall be subject to the  indemnity in such  section) or (2) Tenant's  failure to
perform its obligations under this Lease, unless caused solely by the negligence
or fault of Landlord or its  agents.  This  indemnity  provision  shall  survive
termination  or expiration of this Lease.  If any  proceeding is filed for which
indemnity is required hereunder, Tenant agrees, upon request therefor, to defend
the  indemnified  party in such  proceeding at its sole cost  utilizing  counsel
satisfactory to the indemnified party.


<PAGE>


                  (d)......Landlord's   Indemnity.  Subject  to  Section  10(b),
Landlord shall defend,  indemnify, and hold harmless Tenant from and against all
claims,  demands,  liabilities,  causes of action, suits, judgments and expenses
(including  attorneys'  fees) for any Loss  arising from any  occurrence  at the
Premises caused or materially  contributed to by Landlord's  gross negligence in
acting or failing to act,  and which Loss was not  contributed  to in any way by
Tenant's  actions or omissions.  This indemnity  shall survive the expiration or
termination of this Lease.

         11.      Subordination; Attornment; Notice to Landlord's Mortgagee.

                  (a)......Subordination. This Lease shall be subordinate to any
deed of trust,  mortgage,  or other  security  instrument,  or any ground lease,
master  lease,  or  primary  lease (any such  security  instrument  or lease,  a
"Mortgage"),  that now or hereafter  covers all or any part of the Premises (the
mortgagee under any such mortgage or the lessor under any such lease is referred
to herein as a "Landlord's  Mortgagee").  Any Landlord's Mortgagee may elect, at
any time,  unilaterally,  to make this Lease  superior to its  mortgage,  ground
lease,  or other  interest in the  Premises by so  notifying  Tenant in writing.
Tenant shall execute  agreements  confirming the subordination or superiority of
this Lease to any Mortgage upon Landlord or  Landlord's  Mortgagee's  reasonable
request.

                  (b)......Attornment.   Tenant   shall   attorn  to  any  party
succeeding  to  Landlord's  interest  in  the  Premises,  whether  by  purchase,
foreclosure,  deed in lieu of foreclosure,  power of sale, termination of lease,
or  otherwise,  upon such party's  request,  and shall  execute such  agreements
confirming such attornment as such party may reasonably request.

                  (c)......Notice to Landlord's Mortgagee. Tenant shall not seek
to  enforce  any  remedy  it may have for any  default  on the part of  Landlord
without first giving written notice by certified mail, return receipt requested,
specifying the default in reasonable  detail, to any Landlord's  Mortgagee whose
address has been given to Tenant,  and  affording  such  Landlord's  Mortgagee a
reasonable opportunity to perform Landlord's obligations hereunder.



<PAGE>


                  (d)......Landlord's   Mortgagee's  Protection  Provisions.  If
Landlord's Mortgagee shall succeed to the interest of Landlord under this Lease,
Landlord's  Mortgagee  shall not be: (1) liable for any act or  omission  of any
prior lessor (including  Landlord);  (2) bound by any rent or additional rent or
advance rent which Tenant might have paid for more than the current month to any
prior lessor (including Landlord), and all such rent shall remain due and owing,
notwithstanding  such  advance  payment;  (3) bound by any  security  or advance
rental  deposit made by Tenant which is not delivered or paid over to Landlord's
Mortgagee  and with  respect to which  Tenant  shall look solely to Landlord for
refund or reimbursement; (4) bound by any termination, amendment or modification
of this Lease made without Landlord's  Mortgagee's consent and written approval,
except for those terminations, amendments and modifications permitted to be made
by Landlord without Landlord's  Mortgagee's consent pursuant to the terms of the
loan documents  between  Landlord and Landlord's  Mortgagee;  (5) subject to the
defenses which Tenant might have against any prior lessor (including  Landlord);
and (6) subject to the offsets  which Tenant might have against any prior lessor
(including  Landlord)  except for those offset  rights  which (A) are  expressly
provided in this Lease,  (B) relate to periods of time following the acquisition
of the Premises by  Landlord's  Mortgagee,  and (C) Tenant has provided  written
notice to Landlord's  Mortgagee and provided  Landlord's  Mortgagee a reasonable
opportunity  to cure the event  giving  rise to such  offset  event.  Landlord's
Mortgagee  shall have no  liability or  responsibility  under or pursuant to the
terms of this  Lease or  otherwise  after it  ceases to own an  interest  in the
Premises.  Nothing  in this  Lease  shall be  construed  to  require  Landlord's
Mortgagee to see to the  application  of the proceeds of any loan,  and Tenant's
agreements set forth herein shall not be impaired on account of any modification
of the documents evidencing and securing any loan.

                  (e)......Subordination,    Non-Disturbance    and   Attornment
Agreement.  Simultaneously  upon Tenant's execution of this Lease,  Tenant shall
execute a Subordination,  Non-Disturbance  and Attornment  Agreement in the form
attached   hereto  as  Exhibit  J.  Landlord   shall  return  a  fully  executed
Subordination,  Non-Disturbance  and  Attornment  Agreement in the form attached
hereto  as  Exhibit  J from  the  Lender  named  therein  to  Tenant  as soon as
reasonably possible. Landlord shall use reasonable efforts to obtain a so-called
"nondisturbance agreement" from any further Landlord's Mortgagee.

         12.  Rules and  Regulations.  Tenant  shall  comply  with the rules and
regulations  of the Building  which are attached  hereto as Exhibit C.  Landlord
may, from time to time, change such rules and regulations for the safety,  care,
or  cleanliness  of the  Building  and related  facilities,  provided  that such
changes will not  unreasonably  interfere  with  Tenant's  use of the  Premises.
Tenant shall be responsible  for the compliance  with such rules and regulations
by each Tenant Party.

         13.      Condemnation.

                  (a)......Total Taking.  If the entire  Building or Premises 
are taken by right of eminent  domain or conveyed in lieu
                           ------------
thereof (a "Taking"), this Lease shall terminate as of the date of the Taking.
            ------ 

                  (b)......Partial  Taking - Tenant's Rights. If any part of the
Building  becomes  subject to a Taking and such Taking will prevent  Tenant from
conducting  its business in the Premises in a manner  reasonably  comparable  to
that  conducted  immediately  before  such  Taking for a period of more than one
hundred  eighty (180) days,  then Tenant may terminate this Lease as of the date
of such  Taking by giving  written  notice to Landlord  within  thirty (30) days
after the Taking,  and Rent shall be  apportioned as of the date of such Taking.
If  Tenant  does not  terminate  this  Lease,  then  Rent  shall be  abated on a
reasonable basis as to that portion of the Premises rendered untenantable by the
Taking.



<PAGE>


                  (c)......Partial  Taking - Landlord's  Rights. If any material
portion,  but less than all, of the Building becomes subject to a Taking,  or if
Landlord is required to pay at least $50,000.00 of any of the proceeds  received
for a Taking to a Landlord's  Mortgagee,  then Landlord may terminate this Lease
by  delivering  written  notice  thereof to Tenant within thirty (30) days after
such Taking,  and Rent shall be  apportioned  as of the date of such Taking.  If
Landlord does not so terminate this Lease, then this Lease will continue, but if
any portion of the Premises has been taken,  Rent shall abate as provided in the
last sentence of Section 13.(b). For the purposes of this Section 13 and Section
14, the term "material  portion" shall be deemed to mean at least twenty percent
(20%) of the rentable square feet of the Building.

                  (d)......Award.  If any Taking  occurs,  then  Landlord  shall
receive  the  entire  award or  other  compensation  for the  land on which  the
Building is situated, the Building, and other improvements taken, and Tenant may
separately  pursue a claim (to the extent it will not reduce  Landlord's  award)
against the condemnor for the value of Tenant's  personal  property which Tenant
is entitled to remove under this Lease,  moving  costs,  loss of  business,  and
other claims it may have.

         14.      Fire or Other Casualty.

                  (a)......Repair  Estimate. If the Premises or the Building are
damaged by fire or other casualty (a "Casualty"), Landlord shall, within 90 days
after  such  Casualty,  deliver  to Tenant a good faith  estimate  (the  "Damage
Notice") of the time needed to repair the damage caused by such Casualty.

                  (b)......Landlord's and Tenant's Rights. If a material portion
of the  Building  is damaged by  Casualty  such that  Tenant is  prevented  from
conducting  its business in the Premises in a manner  reasonably  comparable  to
that  conducted   immediately  before  such  Casualty  and  Landlord  reasonably
estimates that the damage caused thereby cannot be repaired  within fifteen (15)
months  after the Casualty (as such period may be extended by the number of days
lost as a result of force majeure  events up to a maximum of one hundred  eighty
(180) days),  then Tenant may terminate this Lease by delivering  written notice
to  Landlord  of its  election to  terminate  within  thirty (30) days after the
Damage  Notice  has been  delivered  to  Tenant.  If  Tenant  does not so timely
terminate this Lease, then (subject to Section 14.(c)) Landlord shall repair the
Building as provided  below,  and Rent for the portion of the Building  rendered
untenantable  by the damage shall be abated on a reasonable  basis from the date
of damage until the completion of the repair,  unless a Tenant Party caused such
damage, in which case, Tenant shall continue to pay Rent without abatement.

                  (c)......Landlord's  Rights.  If a Casualty damages a material
portion of the Building during the last three (3) years of the Term (as the Term
may be extended  pursuant to the  provisions of Exhibit G), and Landlord makes a
good faith  determination that restoring the Building would be uneconomical,  or
if Landlord is required to pay at least  $50,000.00  of any  insurance  proceeds
arising  out of the  Casualty  to a  Landlord's  Mortgagee,  then  Landlord  may
terminate  this Lease by giving  written  notice of its  election  to  terminate
within  thirty (30) days after the Damage  Notice has been  delivered to Tenant,
and  Basic  Rent  and  Additional  Rent  shall be  abated  as of the date of the
Casualty.



<PAGE>


                  (d)......Repair   Obligation.   If  neither  party  elects  to
terminate  this Lease  following  a  Casualty,  then  Landlord  shall,  within a
reasonable  time after such  Casualty,  begin to repair the  Building  and shall
proceed with reasonable  diligence to restore the Building to substantially  the
same condition as it existed immediately before such Casualty; however, Landlord
shall not be  required  to repair or replace  any of the  furniture,  equipment,
fixtures,  and  other  improvements  which may have  been  placed  by, or at the
request of,  Tenant or other  occupants  in the  Building or the  Premises,  and
Landlord's  obligation  to repair or restore the  Building or Premises  shall be
limited to the extent of the insurance  proceeds  actually  received by Landlord
for the Casualty in question.

         15.  Personal  Property  Taxes.  Tenant  shall be liable  for all taxes
levied or assessed against personal property,  furniture,  or fixtures placed by
Tenant in the  Premises.  If any taxes for which  Tenant is liable are levied or
assessed against Landlord or Landlord's  property and Landlord elects to pay the
same, or if the assessed value of Landlord's  property is increased by inclusion
of such personal property,  furniture or fixtures and Landlord elects to pay the
taxes based on such  increase,  then Tenant shall pay to Landlord,  upon demand,
the part of such taxes for which Tenant is primarily liable hereunder;  however,
Landlord  shall not pay such  amount if Tenant  notifies  Landlord  that it will
contest the validity or amount of such taxes before Landlord makes such payment,
and thereafter  diligently proceeds with such contest in accordance with law and
if the  non-payment  thereof  does not pose a threat of loss or  seizure  of the
Building or interest  of Landlord  therein or impose any fee or penalty  against
Landlord.

         16. Events of Default.  Each of the following  occurrences  shall be an
"Event of Default":

                  (a)......Tenant's  failure  to pay Rent  within  five (5) days
after  Landlord  has  delivered  written  notice to Tenant that the same is due;
however,  an Event of Default shall occur  hereunder  without any  obligation of
Landlord to give any notice if Landlord  has given Tenant  written  notice under
this Section  16.(a) on two (2) occasions  during the twelve (12) month interval
preceding such failure by Tenant;

                  (b)......For  more than thirty (30)  consecutive  days or more
than  thirty  (30) days in a ninety  (90) day  period,  Tenant (1)  abandons  or
vacates the Building or more than  twenty-five  percent  (25%)  thereof,  or (2)
fails to continuously operate its business in the Building for the Permitted Use
set forth herein;

                  (c)......Tenant  fails to  provide  any  estoppel  certificate
within the time period  required  under  Section  24.(e) and such failure  shall
continue for five (5) days after written notice thereof from Landlord to Tenant;



<PAGE>


                  (d)......Tenant's  failure to perform, comply with, or observe
any other agreement or obligation of Tenant under this Lease and the continuance
of such  failure for a period of more than thirty (30) days after  Landlord  has
delivered to Tenant written notice  thereof;  provided that if the default is of
such a nature that it may not be reasonably  cured within thirty (30) days, then
no Event of Default shall occur hereunder if Tenant commences curing within such
thirty (30) day period and thereafter  diligently and continuously  pursues such
cure to completion  within a period of not more than  forty-five (45) days after
the delivery of such notice; and

                  (e)......The  filing of a petition  by or against  Tenant (the
term  "Tenant"  shall  include,  for the  purpose of this  Section  16.(e),  any
guarantor of Tenant's  obligations  hereunder);  (1) in any  bankruptcy or other
insolvency proceeding;  (2) seeking any relief under any state or federal debtor
relief law;  (3) for the  appointment  of a  liquidator  or receiver  for all or
substantially  all of Tenant's  property or for Tenant's interest in this Lease;
or (4) for the  reorganization  or modification of Tenant's  capital  structure;
however,  if such a petition is filed against Tenant, then such filing shall not
be an Event of Default unless Tenant fails to have the proceedings  initiated by
such petition dismissed within sixty (60) days after the filing thereof.

         17.  Remedies.  Upon an Event of Default,  Landlord may, in addition to
all other  rights and  remedies  afforded  Landlord  hereunder,  take any of the
following actions:

                  (a)......Terminate  this Lease by giving Tenant written notice
thereof,  in which event  Tenant  shall pay to Landlord  the sum of (1) all Rent
accrued  hereunder  through the date of termination,  (2) all amounts dues under
Section 18.(a),  and (3) an amount equal to (A) the total Rent that Tenant would
have been required to pay for the remainder of the Term plus Landlord's estimate
of aggregate  expenses of reletting to the Premises,  minus (B) the then present
fair rental rate value of the Premises for such period;



<PAGE>


                  (b)......Terminate  Tenant's  right to  possess  the  Premises
without  terminating  this Lease by giving written notice thereof to Tenant,  in
which event Tenant shall pay to Landlord (1) all Rent and other amounts  accrued
hereunder to the date of  termination  of  possession,  (2) all amounts due from
time to time under Section 18.(a),  and (3) all Rent and other net sums required
hereunder to be paid by Tenant during the  remainder of the Term,  diminished by
any net sums  thereafter  received by Landlord  through  reletting  the Premises
during such period,  after deducting all costs incurred by Landlord in reletting
the Premises.  Landlord  shall use  reasonable  efforts to relet the Premises on
such terms as Landlord in its sole  discretion  may determine  (including a term
different from the Term, rental concessions, and alterations to, and improvement
of,  the  Premises);  however,  Landlord  shall  not be  obligated  to relet the
Premises before leasing space in any building owned by Landlord or any Affiliate
thereof  within  a  one  (1)  mile  radius  of  the  Building  (the  "Affiliated
Buildings").  Landlord shall not be liable for, nor shall  Tenant's  obligations
hereunder be diminished  because of, Landlord's failure to relet the Premises or
to collect  rent due for such  reletting.  Tenant  shall not be  entitled to the
excess of any  consideration  obtained by reletting over the Rent due hereunder.
Reentry  by  Landlord  in the  Premises  shall not affect  Tenant's  obligations
hereunder for the unexpired Term; rather, Landlord may, from time to time, bring
an action against Tenant to collect amounts due by Tenant, without the necessity
of Landlord's waiting until the expiration of the Term. Unless Landlord delivers
written notice to Tenant expressly stating that it has elected to terminate this
Lease,  all actions taken by Landlord to  dispossess or exclude  Tenant from the
Premises  shall be deemed to be taken  under this  Section  17.(b).  If Landlord
elects  to  proceed  under  this  Section  17.(b),  it may at any time  elect to
terminate this Lease under Section 17.(a); and

                  (c)......Additionally,  without  notice and provided  Landlord
has  exercised  its rights and remedies set forth in either clause (a) or clause
(b) above, Landlord may alter locks or other security devices at the Premises to
deprive Tenant of access thereto,  and Landlord shall not be required to provide
a new key or right of access to Tenant.

         Any and all remedies set forth in this Lease:  (i) shall be in addition
to any and all other remedies Landlord may have at law or in equity;  (ii) shall
be cumulative; and (iii) may be pursued successively or concurrently as Landlord
may  elect.  The  exercise  of any  remedy  by  Landlord  shall not be deemed an
election of remedies or preclude  Landlord from exercising any other remedies in
the future.  Notwithstanding  the  foregoing,  Landlord  shall only  recover its
damages allowed hereunder once.

         18.      Payment by Tenant; Non-Waiver.

                  (a)......Payment by Tenant. Upon any Event of Default,  Tenant
shall pay to Landlord all costs incurred by Landlord  (including court costs and
reasonable  attorneys'  fees and  expenses) in (1)  obtaining  possession of the
Premises,  (2) removing and storing Tenant's or any other  occupant's  property,
(3)  repairing,  restoring,  altering,  remodeling,  or  otherwise  putting  the
Premises into condition reasonably  acceptable to a new tenant, (4) if Tenant is
dispossessed of the Premises and this Lease is not terminated,  reletting all or
any part of the Premises (including brokerage commissions, cost of tenant finish
work, and other costs  incidental to such  reletting),  (5) performing  Tenant's
obligations  which  Tenant  failed to perform,  and (6)  enforcing,  or advising
Landlord of, its rights,  remedies,  and  recourses  arising out of the Event of
Default.  To the full extent  permitted  by law,  Landlord  and Tenant agree the
federal and state courts of Massachusetts shall have exclusive jurisdiction over
any matter  relating to or arising from this Lease and the  parties'  rights and
obligations under this Lease.

                  (b)......No Waiver. Landlord's acceptance of Rent following an
Event of  Default  shall not waive  Landlord's  rights  regarding  such Event of
Default.  No waiver by Landlord of any  violation  or breach of any of the terms
contained herein shall waive Landlord's rights regarding any future violation of
such term.  Landlord's acceptance of any partial payment of Rent shall not waive
Landlord's  rights with regard to the remaining portion of the Rent that is due,
regardless of any endorsement or other statement on any instrument  delivered in
payment of Rent or any writing delivered in connection  therewith;  accordingly,
Landlord's  acceptance  of a partial  payment  of Rent shall not  constitute  an
accord and satisfaction of the full amount of the Rent that is due.

         19. Landlord's Lien. Intentionally omitted,  provided that the deletion
of this Section shall not be construed to be a waiver of Landlord's  lien rights
provided by law.



<PAGE>


         20.  Surrender  of  Premises.  No act by  Landlord  shall be  deemed an
acceptance  of a  surrender  of the  Premises,  and no  agreement  to  accept  a
surrender of the  Premises  shall be valid unless it is in writing and signed by
Landlord.  At the expiration or termination of this Lease,  Tenant shall deliver
to Landlord the Premises with all  improvements  located  therein in good repair
and condition,  free of Hazardous  Materials  placed on the Premises  during the
Term,  broom-clean,  reasonable  wear and tear (and  condemnation  and  Casualty
damage not  caused by  Tenant,  as to which  Sections  13 and 14 shall  control)
excepted, and shall deliver to Landlord all keys to the Premises.  Provided that
Tenant has performed  all of its  obligations  hereunder,  Tenant may remove all
unattached  trade  fixtures,  furniture,  and  personal  property  placed in the
Premises by Tenant, and shall remove such alterations,  additions, improvements,
trade fixtures, personal property,  equipment, wiring, and furniture as Landlord
may request.  Tenant shall repair all damage caused by such  removal.  All items
not so  removed  shall be  deemed to have been  abandoned  by Tenant  and may be
appropriated,  sold,  stored,  destroyed,  or otherwise  disposed of by Landlord
without  notice to Tenant and without any  obligation to account for such items.
The provisions of this Section 20 shall survive the end of the Term.

         21.  Holding Over. If Tenant fails to vacate the Premises at the end of
the Term,  then  Tenant  shall be a tenant at will and, in addition to all other
damages  incurred  by  Landlord  from and  after  ninety  (90)  days  after  the
expiration of this Lease and remedies to which Landlord may be entitled for such
holding  over,  Tenant  shall pay, in addition to the other Rent,  a daily Basic
Rent equal to 200% of the daily Basic Rent payable  during the last month of the
Term.  The  provisions  of this  Section  21  shall  not be  deemed  to limit or
constitute a waiver of any other rights or remedies of Landlord  provided herein
or at law. If Tenant fails to surrender  the Premises  upon the  termination  or
expiration  of this  Lease,  in addition  to any other  liabilities  to Landlord
accruing therefrom,  Tenant shall protect,  defend,  indemnify and hold Landlord
harmless  from all  loss,  costs  (including  reasonable  attorneys'  fees)  and
liability  resulting  from  such  failure,   including,   without  limiting  the
generality of the foregoing,  any claims made by any  succeeding  tenant founded
upon such  failure to  surrender,  and any lost  profits to  Landlord  resulting
therefrom.

         22. Certain Rights Reserved by Landlord.  Provided that the exercise of
such rights does not  unreasonably  interfere  with  Tenant's  occupancy  of the
Premises, Landlord shall have the following rights:

                  (a)......To   decorate  and  to  make  inspections,   repairs,
alterations,   additions,  changes,  or  improvements,   whether  structural  or
otherwise,  in and about the Building,  or any part  thereof;  to enter upon the
Premises upon reasonable prior notice to Tenant (except in case of an emergency,
in which case no notice shall be required)  and,  during the  continuance of any
such work, to temporarily close doors, entryways, public space, and corridors in
the  Building;  to  interrupt  or  temporarily  suspend  Building  services  and
facilities;  and, to the extent required by governmental authorities,  to change
the arrangement and location of entrances or passageways,  doors,  and doorways,
corridors, elevators, stairs, restrooms, or other public parts of the Building;



<PAGE>


                  (b)......To  take such  reasonable  measures as Landlord deems
advisable  for the security of the Building and its  occupants;  evacuating  the
Building for cause, suspected cause, or for drill purposes;  temporarily denying
access to the Building; and closing the Building after normal business hours and
on Sundays and holidays,  subject,  however, to Tenant's right to enter when the
Building is closed after normal business hours under such reasonable regulations
as Landlord may prescribe from time to time; and

                  (c)......To enter the Premises at  reasonable  hours to show
the Premises to  prospective  purchasers,  lenders,  or,
during the last twelve (12) months of the Term, tenants.

         23.      [Intentionally Omitted].

         24.      Miscellaneous.

                  (a)......Landlord  Transfer. Landlord may transfer any portion
of the Building and any of its rights under this Lease. If Landlord  assigns its
rights  under this Lease,  then  Landlord  shall  thereby be  released  from any
further  obligations  hereunder,  provided that the assignee assumes  Landlord's
obligations hereunder in writing.

                  (b)......Landlord's  Liability.  The  liability of Landlord to
Tenant  for any  default  by  Landlord  under the terms of this  Lease  shall be
limited to Tenant's actual direct, but not  consequential,  damages therefor and
shall be  recoverable  only from the interest of Landlord in the  Building,  and
Landlord shall not be personally  liable for any deficiency.  This Section shall
not limit any remedies  which Tenant may have for  Landlord's  defaults which do
not involve the personal liability of Landlord.

                  (c)......Force  Majeure.  Other than for Tenant's  obligations
under this Lease that can be performed by the payment of money (e.g., payment of
Rent  and  maintenance  of  insurance),  whenever  a  period  of time is  herein
prescribed  for action to be taken by either party hereto,  such party shall not
be liable or responsible  for, and there shall be excluded from the  computation
of any such  period of time,  any delays  due to  strikes,  riots,  acts of God,
shortages  of  labor or  materials,  war,  governmental  laws,  regulations,  or
restrictions,  or any other causes of any kind  whatsoever  which are beyond the
control of such party.  The  provisions of this Section 24(c) shall not apply to
Landlord's  obligations  to construct the Landlord Work and Tenant  Improvements
pursuant to the provisions of this Lease.

                  (d)......Brokerage. Neither Landlord nor Tenant has dealt with
any broker or agent in  connection  with the  negotiation  or  execution of this
Lease, other than Grubb & Ellis Management  Services,  Inc. and Fallon,  Hines &
O'Connor, whose commission shall be paid by Landlord.  Tenant and Landlord shall
each indemnify the other against all costs, expenses, attorneys' fees, and other
liability for commissions or other  compensation  claimed by any broker or agent
claiming the same by, through, or under the indemnifying party.



<PAGE>


                  (e)......Estoppel  Certificates.  From  time to  time,  Tenant
shall furnish to any party designated by Landlord, within ten (10) business days
after  Landlord  has made a written  request  therefor (a copy of which  request
shall  be  simultaneously  sent  to  the  Law  Department  at the  Premises),  a
certificate   signed  by  Tenant   confirming   and   containing   such  factual
certifications  and  representations as to this Lease as Landlord may reasonably
request.

                  (f)......Notices.  All notices and other  communications given
pursuant  to this  Lease  shall be in  writing  and shall be (1) mailed by first
class,  United States Mail,  postage  prepaid,  certified,  with return  receipt
requested,  and addressed to the parties hereto at the address specified next to
their signature block, (2) hand delivered to the intended  address,  or (3) sent
by prepaid  telegram,  cable,  facsimile  transmission,  or telex  followed by a
confirmatory letter. All notices shall be effective upon delivery to the address
of the addressee. The parties hereto may change their addresses by giving notice
thereof to the other in conformity with this provision.

                  (g)......Separability.  If any  clause  or  provision  of this
Lease is illegal,  invalid,  or unenforceable under present or future laws, then
the  remainder  of this Lease shall not be affected  thereby and in lieu of such
clause or  provision,  there  shall be added as a part of this Lease a clause or
provision as similar in terms to such illegal,  invalid, or unenforceable clause
or provision as may be possible and be legal, valid, and enforceable.

                  (h)......Amendments; and Binding Effect. This Lease may not be
amended  except by  instrument  in writing  signed by Landlord  and  Tenant.  No
provision  of this  Lease  shall be deemed to have been  waived by  Landlord  or
Tenant  unless such waiver is in writing  signed by Landlord and Tenant,  and no
custom or practice which may evolve between the parties in the administration of
the terms  hereof  shall  waive or  diminish  the right of Landlord or Tenant to
insist  upon the  performance  by  Tenant in  strict  accordance  with the terms
hereof.  The terms and  conditions  contained  in this Lease  shall inure to the
benefit of and be binding  upon the parties  hereto,  and upon their  respective
successors  in interest and legal  representatives,  except as otherwise  herein
expressly  provided.  This Lease is for the sole benefit of Landlord and Tenant,
and,  other than  Landlord's  Mortgagee,  no third party shall be deemed a third
party beneficiary hereof.

                  (i)......Quiet Enjoyment. Provided Tenant has performed all of
its obligations hereunder, Tenant shall peaceably and quietly hold and enjoy the
Premises for the Term, without hindrance from Landlord or any party claiming by,
through,  or  under  Landlord,  but not  otherwise,  subject  to the  terms  and
conditions of this Lease.

                  (j)......No Merger.  There shall be no merger of the leasehold
estate hereby created with the fee estate in the Premises or any part thereof if
the same person  acquires or holds,  directly or  indirectly,  this Lease or any
interest  in this  Lease and the fee  estate in the  leasehold  Premises  or any
interest in such fee estate.



<PAGE>


                  (k)......No Offer.  The  submission  of this Lease to Tenant
shall not be construed  as an offer,  and neither  party
                           --------
shall have any rights under this Lease until both parties execute a copy of 
this Lease.

                  (l)......Entire  Agreement.  This Lease constitutes the entire
agreement  between  Landlord and Tenant  regarding the subject matter hereof and
supersedes all oral statements and prior writings relating  thereto.  Except for
those set forth in this Lease,  no  representations,  warranties,  or agreements
have been made by Landlord or Tenant to the other with  respect to this Lease or
the obligations of Landlord or Tenant in connection  therewith.  The normal rule
of  construction  that any  ambiguities  be resolved  against the drafting party
shall  not  apply  to the  interpretation  of  this  Lease  or any  exhibits  or
amendments hereto.

                  (m)......Waiver of Jury Trial.  To the  maximum  extent  
permitted  by law,  Landlord  and Tenant each waive right to
                           --------------------
trial by jury in any litigation arising out of or with respect to this Lease.

                  (n)......Governing  Law. This Lease shall be governed by and
  construed in  accordance  with the laws of the State in
                           --------------
which the Premises are located.

                  (o)......Joint and Several  Liability.  If Tenant is comprised
of more than one party,  each such party shall be jointly and  severally  liable
for Tenant's obligations under this Lease. If Landlord is comprised of more than
one party,  each such party shall be jointly and severally liable for Landlord's
obligations under this Lease.

                  (p)......Financial  Reports.  Within  fifteen  (15) days after
Landlord's  request,  Tenant will furnish Tenant's most recent audited financial
statements  (including  any notes to them) to  Landlord,  or, if no such audited
statements  have been prepared,  such other  financial  statements (and notes to
them) as may have been prepared by an independent  certified  public  accountant
or, failing those,  Tenant's  internally prepared financial  statements.  Tenant
will discuss its  financial  statements  with  Landlord  and will give  Landlord
access to Tenant's  books and records in order to enable  Landlord to verify the
financial  statements.  Landlord  will  not  disclose  any  aspect  of  Tenant's
financial  statements that Tenant designates to Landlord as confidential  except
(1) to Landlord's  Mortgagee or prospective  purchasers of the Building,  (2) in
litigation between Landlord and Tenant, and/or (3) if required by court order.

                  (q)......Landlord's Fees. Whenever Tenant requests Landlord to
take any action or give any  consent  required  or  permitted  under this Lease,
Tenant will reimburse Landlord for Landlord's  reasonable,  actual out-of-pocket
costs incurred in reviewing the proposed  action or consent,  including  without
limitation reasonable attorneys',  engineers' or architects' fees, within thirty
(30) days after  Landlord's  delivery  to Tenant of a  statement  of such costs.
Tenant will be obligated to make such  reimbursement  without  regard to whether
Landlord consents to any such proposed action.



<PAGE>


                  (r)......Telecommunications.  Subject  to  the  provisions  of

installation that would affect the Building's  structure or its HVAC,  plumbing,
electrical,  or  mechanical  systems or any other  improvements  or any of their
respective  HVAC,  plumbing,  electrical or mechanical  systems,  if any. Tenant

Lease,  Tenant shall restore the Premises and any other affected property to the
condition that existed on the date of this Lease. Any and all such installations

systems,  including,  without limitation, any representations or warranties with
respect to the  structural  integrity,  the adequacy  and/or utility of any such
telecommunications systems and/or their compliance with applicable Laws.

and all  claims,  demands,  liabilities,  causes of  action,  suits,  judgments,
damages  and  expenses  (including  attorneys'  fees  and  cost of  clean up and
remediation) arising from Tenant's failure to comply with the provisions of this
Section 24.(u). This indemnity provision shall survive termination or expiration
of the Lease.  Except as set forth in the Environmental  Reports (as hereinafter

                  (x)......Notice  of Lease.  Tenant  agrees not to record  this
Lease and,  subject to the provisions of Section 24(t) above,  to keep the terms

<PAGE>

<PAGE>


                  (bb).....Rooftop  Equipment.  Tenant may install,  at Tenant's
risk and expense and to be used  solely by Tenant,  a dish style  antennae of no
more than five (5) feet in diameter (the "Rooftop Equipment") on the roof of the
Building  at a location  approved by  Landlord.  Before  installing  the Rooftop
Equipment,   Tenant  shall  submit  to  Landlord  for  its  approval  plans  and
specifications which (A) specify in detail the design,  location and size of the
Rooftop   Equipment   (and,  with  respect  to  the  Rooftop   Equipment,   such
specifications  shall also contain the frequency of such  equipment) and (B) are
sufficiently  detailed to allow for the installation of the Rooftop Equipment in
a good and  workmanlike  manner  and in  accordance  with all Laws.  None of the
Rooftop  Equipment shall protrude more than five (5) feet above the elevation of
the roof on which it is installed  and all such  equipment  must be painted in a
color  reasonably  acceptable  to Landlord to minimize  visibility.  If Landlord
approves of such plans (which  approval  shall not be  unreasonably  withheld or
delayed unless the  installation of any Rooftop  Equipment  penetrates the roof,
affects the Building's structure or any of its HVAC, mechanical,  electrical and
plumbing  equipment,  or violates or in any way  compromises any roof warranty),
Tenant shall install (in a good and  workmanlike  manner),  maintain and use the
Rooftop  Equipment in accordance with all Laws and shall obtain all consents and
permits required for the installation and operation thereof;  copies of all such
permits and  evidence of such  consents  must be  submitted  to Landlord  before
Tenant begins to install the Rooftop Equipment. Tenant shall thereafter maintain
all permits necessary for the maintenance and operation of the Rooftop Equipment
while it is on the Building. Landlord may require that Tenant screen the Rooftop
Equipment with a parapet or other screening device  acceptable to Landlord.  All
electrical  usage for the Rooftop  Equipment shall be separately  metered or, at
Landlord's  election,  shall  be  placed  on the  same  electrical  meter as the
Premises.  Tenant shall maintain the Rooftop  Equipment and screening  device in
good repair and  condition.  Landlord  may  relocate  the Rooftop  Equipment  to
another  location on the roof of the  Building at its sole cost and expense upon
prior written  notice to Tenant so long as the new location does not  materially
interfere with Tenant's  reception  received by the satellite or antennae.  Upon
reasonable  prior notice to  Landlord,  Tenant  shall,  at its risk and expense,
remove the Rooftop Equipment (including all wiring related thereto), within five
(5)  days  after  the  occurrence  of any  of  the  following  events:  (i)  the
termination of Tenant's right to possess the Premises;  (ii) the  termination of
the Lease;  (iii) the  expiration  of the Term;  or (iv) the  Premises  shall be
vacated  by Tenant  and any and all  assignees  and/or  sublessees  approved  by
Landlord  hereunder.  If Tenant  fails to do so,  Landlord may remove all or any
part of the Rooftop  Equipment and store or dispose of it in any manner Landlord
deems appropriate  without liability to Tenant;  Tenant shall reimburse Landlord
for all costs incurred by Landlord in connection  therewith within ten (10) days
after  Landlord's  request  therefor.  Tenant  shall  repair  any  damage to the
Building caused by or relating to the Rooftop Equipment, including that which is
caused by its  installation,  maintenance,  use, or removal and shall  indemnify
Landlord against all liabilities,  losses,  damages,  and costs arising from the
installation,  maintenance, use, or removal of the Rooftop Equipment (unless the
liabilities,  losses,  damages,  and costs in question were caused by Landlord's
sole or gross negligence or wilful misconduct). All work relating to the Rooftop
Equipment shall, at Tenant's  expense,  be coordinated  with Landlord's  roofing
contractor  so as not to affect any warranty for the  Building's  roof and shall
not penetrate the roof.

(cc).....Access.  Tenant shall have  twenty-four  (24) hour access to the 
Premises  seven (7) days a week (subject to                         
force majeure, emergency, etc.).

                  (dd).....Arbitration.   (1)  In  any   case  in  which  it  is
specifically  provided  by the  terms  of this  Lease  that a  matter  shall  be
determined  by  arbitration,  such  arbitration  shall be conducted  pursuant to
applicable  statutes of The  Commonwealth of Massachusetts at the time in effect
and, to the extent  permitted by said statutes,  in the manner specified in this
Section 24(dd) and, to the extent not  inconsistent  with said statutes and this
Section 24(dd), in accordance with the Commercial  Arbitration Rules at the time
in effect of the American Arbitration Association; provided that all arbitrators
selected   hereunder   shall  be  persons  of  recognized   competence  who  are
unaffiliated  with either party  (either by direct or indirect  relationship  or
significant  business  relationship)  and shall  have at least  ten (10)  years'
experience as a commercial real estate broker or appraiser in the Greater Boston
area.

         (2) The party  desiring such  arbitration  shall give written notice to
that effect to the other party and, in such notice,  shall specify the nature of
the  dispute  to be  arbitrated  and shall  appoint  one of the  arbitrators  in
accordance with the requirements of Section 24(dd)(1).  Within fifteen (15) days
thereafter,  the other  party  shall by  written  notice to the  original  party
appoint a second person as an arbitrator in accordance with the  requirements of
this Section 24(dd)(1). The arbitrators thus appointed, within fifteen (15) days
of the appointment of the second such  arbitrator,  shall appoint a third person
in accordance  with the  requirements of Section  24(dd)(1),  and such three (3)
arbitrators shall determine such matter as promptly as possible; provided that:

 (A)......if the second  arbitrator shall not have been appointed as aforesaid,
  the first arbitrator shall proceed to
  determine the matter; and



<PAGE>


                  (B)......if the two (2)  arbitrators  appointed by the parties
                  shall be unable to agree  within  fifteen  (15) days after the
                  appointment of the second arbitrator upon the appointment of a
                  third  arbitrator,  they  shall  give  written  notice of such
                  failure to agree to the  parties,  and, if the parties fail to
                  agree  upon the  selection  of such  third  arbitrator  within
                  fifteen  (15) days  after  the  arbitrators  appointed  by the
                  parties given notice as  aforesaid,  then within ten (10) days
                  thereafter  either of the parties upon  written  notice to the
                  other  party,   may  request  such  appointment  by  the  then
                  Governing  Board of the New  England  Chapter of the  American
                  Institute of Real Estate  Appraisers (or any organization that
                  may be successor thereto) or, in its absence, refusal, failure
                  or  inability to act,  may apply for such  appointment  to any
                  Court of The  Commonwealth  of  Massachusetts  having  general
                  equity  powers or to any other court having  jurisdiction  and
                  exercising functions similar to such court.

         (3)  The  arbitrator  or  arbitrators  shall  have  the  right  only to
interpret  and apply the terms of this Lease,  and may not change any such terms
or deprive any party to this Lease of any right or remedy expressly or impliedly
provided  in this Lease.  Landlord  and Tenant each shall be entitled to present
evidence and arguments to the arbitrators.

         (4) The determination of the majority of the arbitrators or of the sole
arbitrator,  as the case may be, shall be final and binding in  accordance  with
the provisions of M.G.L.  c. 241. The  arbitrators  shall give written notice of
their  determination  to Landlord and Tenant and shall  furnish to each a signed
copy of such determination.

         (5) The fees and expenses of all arbitrators  shall be borne equally by
Landlord and Tenant.

         (6) In the event of the failure, refusal or inability of any arbitrator
to act, a new  arbitrator  shall be  appointed in his stead,  which  appointment
shall be made in the same manner as hereinbefore provided for the appointment of
the arbitrator so failing, refusing or unable to act, or to continue to act.

         (7) During any period of  arbitration  under this Section 24(dd) of any
matter stated in this Lease to be specifically  subject to arbitration,  neither
Landlord  nor  Tenant  shall be  deemed to be in  default  with  respect  to the
performance of any covenant, duty or obligation relating to such matter, and any
grace period or permitted delay in such  performance  otherwise  provided for in
this Lease shall be automatically extended by such period of arbitration.

                  (ee).....Campus Setting. At Tenant's request and sole cost and
expense,  Landlord shall use  reasonable  efforts to assist Tenant in creating a
campus environment;  provided,  however,  (i) any alterations to the Premises by
Tenant  shall be subject to the  provisions  of this  Lease,  including  without
limitation,  Section 7, (ii)  Landlord  shall not be required to render any such
assistance on a matter which would adversely  affect the Premises in any manner,
(iii) Landlord shall only render such  assistance  with respect to the Premises,
and (iv)  nothing  in this  Lease  is  intended  to  permit  Tenant  to make any
alterations to any property other than the Premises.

                                    EXHIBIT D

                      LANDLORD WORK AND TENANT IMPROVEMENTS

         1. Except as set forth in this Exhibit,  Tenant accepts the Premises in
their "AS-IS" condition on the date that this Lease is entered into.

         2. Landlord shall have no obligation to perform any work therein except
for the following  (collectively,  the "Landlord Work"): (i) Landlord will clean
the carpets in the Building; (ii) Landlord will repair any holes in the interior
walls of the  Building;  and  (iii)  the HVAC and  mechanical  systems  shall be
delivered in good working order.

         3. Tenant  shall  provide to Landlord for its  approval  final  working
drawings,  prepared by an architect  that has been  approved by Landlord  (which
approval shall not unreasonably be withheld),  of all  improvements  that Tenant
proposes to install in the  Premises;  such working  drawings  shall include the
partition  layout,  ceiling plan,  electrical  outlets and  switches,  telephone
outlets,  drawings for any  modifications to the mechanical and plumbing systems
of the Building,  and detailed plans and  specifications for the construction of
the improvements called for under this Exhibit in accordance with all applicable
governmental  laws, codes,  rules, and regulations.  If any of Tenant's proposed
construction work will affect the Building's HVAC,  electrical,  mechanical,  or
plumbing systems,  then the working drawings pertaining thereto must be approved
by the  Building's  engineer  of record.  Landlord's  approval  of such  working
drawings shall not be unreasonably withheld,  provided that (a) they comply with
all laws,  rules,  and  regulations,  (b) such working drawings are sufficiently
detailed to allow  construction  of the  improvements  in a good and workmanlike
manner,  and (c) the  improvements  depicted  thereon  conform  to the rules and
regulations  promulgated  from time to time by the Landlord for the construction
of tenant  improvements (a copy of which has been delivered to Tenant).  As used
herein,  "Working  Drawings" shall mean the final working  drawings  approved by
Landlord,  as amended from time to time by any  approved  changes  thereto,  and
"Work" shall mean all  improvements  to be constructed in accordance with and as
indicated on the Working Drawings.  Landlord's  approval of the Working Drawings
and/or  review of any of the Work shall not be a  representation  or warranty of
Landlord that such drawings and/or any Work, as applicable, are adequate for any
use or comply with any law, but shall merely be the consent of Landlord thereto.
Landlord shall, at Tenant's  request,  sign the Working Drawings to evidence its
review and  approval  thereof.  All  changes in the Work must  receive the prior
written  approval  of  Landlord,  and in the event of any such  approved  change
Tenant shall,  upon completion of the Work,  furnish  Landlord with an accurate,
reproducible "as-built" plan of the improvements as constructed.



<PAGE>


         4. The Work shall be performed only by contractors  and  subcontractors
approved  in writing  by  Landlord,  which  approval  shall not be  unreasonably
withheld.  All contractors and  subcontractors  shall be required to procure and
maintain insurance against such risks, in such amounts,  and with such companies
as Landlord may reasonably  require.  Certificates of such insurance,  with paid
receipts  therefor,  must be received by Landlord  before the Work is commenced.
Promptly upon Landlord's approval of the Working Drawings, Tenant shall commence
the  construction  of the  Work  and  diligently  and  continuously  pursue  the
completion  of the same.  The Work shall be performed in a good and  workmanlike
manner free of defects,  shall conform strictly with the Working  Drawings.  All
contractors and subcontractors  shall contact Landlord and schedule time periods
during which they may use Building facilities in connection with the Work (e.g.,
elevators, excess electricity, etc.).

         5.  The  entire  cost  of  performing  the  Work  (including,   without
limitation, design of the Work and preparation of the Working Drawings, costs of
construction,   labor  and  materials,  electrical  usage  during  construction,
additional  janitorial  services,  general  tenant  signage,  related  taxes and
insurance  costs, all of which costs are herein  collectively  called the "Total
Construction  Costs") in excess of the  Construction  Allowance (as  hereinafter
defined) shall be paid by Tenant.

         6.  Landlord  shall  provide to Tenant a  construction  allowance  (the
"Construction  Allowance") equal to the lesser of (a) $10.00 per rentable square
foot in the Premises or (b) the Total  Construction  Costs,  as adjusted for any
approved changes to the Work.

         Subject to the terms and  conditions of this Lease,  Landlord shall pay
the  Construction  Allowance to Tenant for the purpose of financing a portion of
the Work. As conditions to Tenant's right to receive the Construction Allowance:
(i) Tenant shall not be in default  under the Lease;  (ii) the Lease shall be in
full  force and  effect;  (iii) the Work  shall  be,  in  Landlord's  reasonable
discretion,  substantially  complete; and (iv) Tenant shall furnish to Landlord:
(A) a Certificate of Occupancy respecting the Premises; and (B) such evidence as
Landlord  may  reasonably  require to evidence  that all persons  furnishing  or
supplying  labor and materials in connection  with the  construction of the Work
have been paid and that no lien exists of record with respect thereto.  Landlord
shall fund the  Construction  Allowance  within  twenty (20)  business days from
Tenant's written request for the same provided that Tenant has complied with the
requirements set forth in the preceding sentence. Upon paying the full amount of
the Construction  Allowance to Tenant in accordance with the provisions  hereof,
Landlord shall have no further obligation to extend any credit to Tenant.

         7. In  consideration  for  Landlord's  management  and  supervision  of
services  performed in connection  with the Work,  Tenant shall pay to Landlord,
within ten (10) business days after demand  therefor,  the actual costs incurred
by  Landlord  to  review  the  Working   Drawings   and/or  any  drafts   and/or
modifications thereto and to review the construction of the Work.

                                     PARKING

         Landlord  shall  provide,  and Tenant may use three  hundred  one (301)
undesignated  parking  spaces in the  parking  garage/area  associated  with the
Building (the "Parking  Area") during the initial Term at no additional  charge.
After the initial Term,  Tenant may use such parking  spaces and pay for the use
of such parking  spaces at such rates and subject to such terms,  conditions and
regulations  as are from time to time  charged or  applicable  to patrons of the
Parking Area or similar parking areas.  If, for any reason,  Tenant is unable to
use all or any portion of the parking spaces to which it is entitled  hereunder,
then Tenant's  obligations to pay for such spaces shall be abated for so long as
Tenant does not have the use thereof; this abatement shall be in full settlement
of all claims that Tenant  might  otherwise  have  against  Landlord  because of
Landlord's failure or inability to provide Tenant with such parking spaces.

                                    EXHIBIT G

                                 RENEWAL OPTION

         Provided no Event of Default  exists at the time Tenant  exercises  its
option to extend this Lease and at the time the  extension  Term  commences  and
Tenant is occupying at least  seventy-five  percent (75%) of the Premises at the
time of such election, Tenant may renew this Lease for one (1) additional period
of five (5) years,  by  delivering  written  notice of the exercise  thereof not
later than ten (10) months  before the  expiration of the Term. On or before the
commencement  date of the extended  Term in question,  Landlord and Tenant shall
execute an amendment to this Lease extending the Term on the same terms provided
in this Lease, except as follows:

                  (a) The Basic Rent  payable  for each month  during  each such
extended Term shall be the Fair Market Rental Value, at the commencement of such
extended Term, for space of equivalent quality, size, utility and location, with
the length of the  extended  Term and the credit  standing of Tenant to be taken
into account;

                  (b)  Tenant  shall  have no  further  renewal  options  unless
expressly granted by Landlord in writing; and

                  (c)  Landlord  shall  lease to Tenant  the  Premises  in their
then-current  condition,  and Landlord shall provide to Tenant  mutually  agreed
upon allowances (e.g., moving allowance,  construction allowance,  and the like)
or other tenant inducements.

         Tenant's rights under this Exhibit shall terminate if (1) this Lease or
Tenant's right to possession of the Premises is  terminated,  (2) Tenant assigns
any of its interest in this Lease or sublets more than twenty-five percent (25%)
of the  Premises or (3) Tenant  fails to timely  exercise  its option under this
Exhibit, time being of the essence with respect to Tenant's exercise thereof.

         For purposes of this Lease,  the term "Fair Market  Rental Value" shall
mean the fair market rental value of the Premises as of the  commencement of the
extension Term and/or expansion space (as applicable),  as agreed by the parties
hereto.  In the event that  Landlord  and Tenant are unable to agree on the Fair
Market  Rental Value of the Premises for purposes  hereof within sixty (60) days
following  Tenant's  notice of its election to extend this Lease or to lease the
expansion  space,  then the same shall be determined by binding  arbitration  in
accordance with Section 24(dd).

         The arbitrators, as chosen pursuant to Section 24(dd), shall make their
respective  determinations based upon the following  assumptions and directions,
and the arbitrators shall be so instructed and duty bound with respect thereto:

                  (i) the  space is  available  in the then  rental  market  for
                  single tenant buildings of comparable  office buildings in the
                  495 North markets;



<PAGE>


                  (ii) Landlord has had a reasonable time to locate a tenant for
                  such space who rents with the  knowledge  of the uses to which
                  the space can be utilized;

                  (iii)  neither Landlord nor the prospective tenant is under a 
                         compulsion to rent;

                  (iv) such space is to be rented as a whole to a single  tenant
                  for general  office use for a term of at least five (5) years,
                  taking into  consideration such market factors and other lease
                  provisions as may then customarily be in effect and applicable

             SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT


     This AGREEMENT is made and entered into as of ___________________, 1999, by
and  among  LaSalle  National  Bank,  as  Trustee  for  GS  Mortgage  Securities
Corporation II Commercial Mortgage Pass-Through Certificates,  Series 1998-GSFL1
("Lender"),  W9/TIB  Real Estate  Limited  Partnership  ("Landlord")  and Kronos
Incorporated ("Tenant").

     1.   RECITALS.

          1.1  Mortgage.  Lender  is  the  holder  of a  Promissory  Note  dated
________________, 19____, in the original principal amount of $_________________
of Landlord,  which is secured, inter alia, by a Mortgage and Security Agreement
(the  "Mortgage")  and  Assignment  of Lease and Rents (the "Lease  Assignment")
covering premises more particularly described in the Mortgage (the "Premises").

          1.2 Lease.  Landlord and Tenant entered into a Lease dated January __,
1999 (the "Lease"), whereby Landlord demised to Tenant a portion of the Premises
(the "Demised Premises").

     2.  CONSIDERATION.  The terms of the Lease constitute a material inducement
to Lender's consent thereto and entering into and performing this Agreement.

     3.  SUBORDINATION  OF THE  LEASE.  This Lease  shall be and is hereby  made
subject and subordinate to the Mortgage.

     4. NON-DISTURBANCE. Lender shall not, in the exercise of any right, remedy,
or  privilege  granted by the  Mortgage or the Lease  Assignment,  or  otherwise
available to Lender at law or in equity,  disturb Tenant's  possession under the
Lease so long as:

     (a)  Tenant  is not in  default  under any  provision  of the Lease or this
Agreement  beyond any  applicable  notice and/or cure periods at the time Lender
exercises any such right, remedy or privilege; and

     (b) The Lease at that time is in force and effect according to its original
terms, or with such amendments or  modifications  as Lender shall have approved,
if  such  approval  is  required  by the  terms  of the  Mortgage  or the  Lease
Assignment; and

     (c) Tenant thereafter  continues to fully and punctually perform all of its
obligations  under the Lease without  default  thereunder  beyond any applicable
cure period; and

     (d)  Tenant  attorns  to or at the  direction  of Lender,  as  provided  in
Paragraph 5.


<PAGE>


Without limiting the foregoing, and so long as the foregoing conditions are met,
Lender agrees that (i) Tenant will not be named as a party to any foreclosure or
other  proceeding  instituted  by Lender to enforce the terms of the Mortgage or
the Lease Assignment; (ii) any sale or other transfer of the Demised Premises or
of the  Landlord's  interest  in  the  Lease,  pursuant  to  foreclosure  or any
voluntary conveyance or other proceeding in lieu of foreclosure, will be subject
and subordinate to Tenant's possession under the Lease; and (iii) the Lease will
continue  in force and effect  according  to its  original  terms,  or with such
amendments  as Lender shall have  approved,  if such approval is required by the
terms and conditions of the Mortgage or the Lease Assignment.

     5.  ATTORNMENT.  Tenant shall attorn to Lender,  to any receiver or similar
official for the Demised Premises appointed at the instance and request, or with
the consent,  of Lender and to any person who acquires the Demised Premises,  or
the Landlord's  interest in the Lease, or both, pursuant to Lender's exercise of
any right,  remedy or privilege granted by the Mortgage,  or otherwise at law or
in equity. Without limitation,  Tenant shall attorn to any person or entity that
acquired the Demised Premises pursuant to foreclosure of the Mortgage, or by any
proceeding or voluntary conveyance in lieu of such foreclosure,  or from Lender,
whether by sale,  exchange or  otherwise.  Any  attornment  to anyone other than
Lender shall be conditioned  upon Tenant receiving a  non-disturbance  from such
entity.

     Upon any  attornment  under this  Paragraph 5, the Lease shall  continue in
full force and effect as a direct lease between  Tenant and the person or entity
to whom Tenant attorns, except that such person or entity shall not be:

     (i)  liable for any breach, act or omission of any prior landlord; or

     (ii)  subject to any  offsets,  claims or defenses  which Tenant might have
against any prior landlord; or

     (iii)bound by any rent or additional  rent or other payment in lieu of rent
which Tenant might have paid to any prior  landlord more than 30 days in advance
of its due date  under the Lease or which  such  person or entity  has  physical
possession of; or

     (iv) bound by any  amendment  or  modification  of the Lease  made  without
Lender's written consent, where such consent is required by the Mortgage; or

     (v) bound by any notice  given by Tenant to  Landlord,  whether or not such
notice is given  pursuant to the terms of the Lease,  unless a copy  thereof was
then also given to Lender; or

     (vi) be liable  for any  security  deposit  or other sums held by any prior
landlord, unless actually received.



<PAGE>


The person or entity to whom Tenant  attorns shall be liable to Tenant under the
Lease  only  during  such  person  or  entity's  period of  ownership,  and such
liability shall not continue or survive as to the transferor after a transfer by
such person or entity of its interest in the Lease and the Demised Premises.

     6.   REPRESENTATIONS AND WARRANTIES.

          6.1 Landlord and Tenant each hereby represent and warrant to Lender as
follows regarding the Lease:

     (a) A true and  correct  copy of the Lease  (inclusive  of all  riders  and
exhibits  thereto)  is  attached  to the  counterpart  of this  Agreement  being
delivered   to  Lender.   There  are  no  other  oral  or  written   agreements,
understandings  or the like between  Landlord and Tenant relating to the Demised
Premises or the Lease transaction.

     (b) The term of the Lease is expected  to  commence  on or about  August 1,
1999.

     (c) Under the Lease,  Tenant shall be obligated to pay rent without present
right of defense or offset,  at the rate of $54,818.67  per month.  Rent is paid
through  and  including  N/A , 19__.  No rent has been paid more than 30 days in
advance,  and Tenant has no claim against the Landlord for any deposits or other
sums.

     (d) The Lease has not been modified, altered or amended in any respect.

     (e) All of the  improvements  contemplated  by the Lease have been entirely
completed as required therein.

     (f) The  addresses for notices to be sent to Tenant and Landlord are as set
forth in the Lease.

     (g) To Tenant's knowledge,  Tenant has no right of first refusal, option or
other right to purchase the  Premises or any part  thereof,  including,  without
limitation, the Demised Premises.

     6.2 Several.  Landlord and Tenant severally represent and warrant to Lender
with respect to themselves, but not with respect to the other:

     (a) The execution of the Lease was duly authorized,  the Lease was properly
executed and is in full force and effect and is valid,  binding and  enforceable
against Tenant and Landlord and there exists no monetary default or, to the best
of their  knowledge,  no  non-monetary  default,  nor state of facts  which with
notice, the passage of time, or both, could ripen into a default, on the part of
either Tenant or Landlord.

     (b)  There  has not  been  filed  by or  against  nor,  to the  best of the
knowledge and belief of the representing  party, is there threatened  against or
contemplated  by,  Landlord or Tenant,  a petition in  bankruptcy,  voluntary or
otherwise,  any  assignment for the benefit of creditors,  any petition  seeking
reorganization  or arrangement under the bankruptcy laws of the United States or
of any state thereof, or any other action brought under said bankruptcy laws.


<PAGE>


     (c) There has not been any assignment, hypothecation or pledge of the Lease
or rents accruing  under the Lease,  other than pursuant to the Mortgage and the
Lease Assignment. Tenant makes the representation set forth in this subparagraph
only to its best knowledge and belief.

     7. RENTS.  Landlord and Tenant jointly and severally  acknowledge  that the
Lease  Assignment  provides  for the  direct  payment to Lender of all rents and
other  monies  due and to  become  due to  Landlord  under  the  Lease  upon the
occurrence of certain  conditions as set forth in the Lease  Assignment  without
Lender's  taking  possession  of the  Demised  Premises  or  otherwise  assuming
Landlord's  position  or any of  Landlord's  obligations  under the Lease.  Upon
receipt from Lender of written  notice to pay all such rents and other monies to
or at the direction of Lender, Landlord authorizes and directs Tenant thereafter
to make all such payments to or at the direction of Lender,  releases  Tenant of
any and all  liability  to Landlord  for any and all payment so made,  and shall
defend,  indemnify and hold Tenant harmless from and against any and all claims,
demands,  losses, or liabilities  asserted by, through or under Landlord (except
by Lender) for any and all payments so made. Upon receipt of such notice, Tenant
thereafter  shall pay all monies then due and becoming due from Tenant under the
Lease to or at the  direction of Lender,  notwithstanding  any  provision of the
Lease  to the  contrary.  Tenant  agrees  that  neither  Lender's  demanding  or
receiving any such payments,  nor Lender's  exercising any other right,  remedy,
privilege,  power or immunity  granted by the Mortgage or the Lease  Assignment,
will  operate  to impose  any  liability  upon  Lender  for  performance  of any
obligation of Landlord under the Lease unless and until Lender elects  otherwise
in writing.  Such payments shall continue until Lender directs Tenant  otherwise
in writing.

     Tenant  agrees  not to pay any rent  under the  Lease  more than 30 days in
advance without Lender's consent.  The provisions of this Paragraph 7 will apply
from time to time throughout the term of the Lease.

     8. CURE.  If Tenant  becomes  entitled  to  terminate  the Lease or offset,
withhold or abate rents  because of any default by  Landlord,  then Tenant shall
give Lender written notice specifying Landlord's default. Lender then shall have
the right,  but not the  obligation,  to cure the specified  default  within the
following time periods:

     (a) Fifteen days after receipt of such notice with respect to defaults that
can be cured by the payment of money; or

     (b) Thirty  days after  receipt of such  notice  with  respect to any other
default;  unless the cure  requires  Lender to obtain  possession of the Demised
Premises,  in which case such thirty day period shall not commence  until Lender
acquires  possession,  so long as Lender proceeds promptly to acquire possession
of the Demised  Premises with due  diligence,  by foreclosure of the Mortgage or
otherwise.



<PAGE>


Nothing  contained  in this  Paragraph  8 shall  require  Lender to  commence or
continue any foreclosure or other proceedings, or, if Lender acquires possession
of the Demised Premises, to continue such possession,  if all defaults specified
by Tenant in its notice are cured.  Possession  by a receiver,  or other similar
official  appointed  at the  instance,  or with the  consent,  of  Lender  shall
constitute possession by Lender for all purposes under this Paragraph 8.

     9. ESTOPPEL LETTERS.  Whenever reasonably requested by Lender, Landlord and
Tenant  from time to time  shall  severally  execute  and  deliver  to or at the
direction  of  Lender,  and  without  charge  to  Lender,  one or  more  written
certifications of all of the matters as set forth in Paragraph 6, whether Tenant
has exercised any renewal option or options and any other information the Lender
may reasonably  require to confirm the current  status of the Lease,  including,
without limitation, a confirmation that the Lease is and remains subordinated as
provided in this Agreement.

     10. CASUALTY AND EMINENT DOMAIN.  Landlord and Tenant jointly and severally
agree  that  the  Mortgage  permits  Lender,  at its  option,  to  apply  to the
indebtedness  from time to time secured by the  Mortgage  any and all  insurance
proceeds  payable with respect to any casualty loss at the Demised  Premises and
any  and  all  awards  or  other  compensation  that  may  be  payable  for  the
condemnation  of all or any portion of the  Demised  Premises,  or any  interest
therein,  or  by  way  of  negotiated   settlement  or  conveyance  in  lieu  of
condemnation;  and Landlord and Tenant jointly and severally consent to any such
application by Lender.  Notwithstanding the foregoing, Landlord and Lender agree
that any and all  insurance  or  condemnation  proceeds  payable with respect to
Tenant's property or the interruption or relocation of Tenant's business (except
for rental loss insurance  proceeds) will be paid to Tenant,  so long as they do
not reduce the proceeds otherwise payable to Lender.

     11. NOTICES.  All notices,  demands,  and other communications that must or
may be given or made in connection  with this  Agreement must be in writing and,
unless receipt is expressly  required,  will be deemed  delivered or made 5 days

and  deliver at  Lender's  request  all  instruments  that may be  necessary  or

     14.   COUNTERPARTS.   This  Agreement  may  be  executed  in  one  or  more
counterparts,   each  of  which  shall  be  deemed  an  original  and  all  such

unenforceable or invalid shall not affect the  enforceability or validity of any
other provision,  and any determination that the application of any provision of
this Agreement to any person or to any person or to particular  circumstances is
illegal or unenforceable shall not affect the enforceability or validity of such
provision as it may apply to other persons or circumstances.

                                    EXHIBIT K

                       RIGHT OF FIRST OFFER RE 4 OMNI WAY

         Subject to the rights of existing  tenants to continue to occupy  their
respective  premises and to any now or hereafter  arising extension or expansion
options of other tenants, provided no Event of Default then exists, and provided
Tenant has a net worth equal to or greater  than  ninety-five  percent  (95%) of
Tenant's  net worth as of the date hereof,  Landlord  shall,  after  receiving a
formal request for proposal to which Landlord elects to respond (other than from
the  then-current  tenant  therein),  first  offer to lease to Tenant  the space
designated on page 2 of this Exhibit (the "4 Omni Way Offer Space");  such offer
shall be in writing and specify the market  lease terms for the 4 Omni Way Offer
Space, including a lease term of at least five (5) years, the Fair Market Rental
Value (as  determined in  accordance  with Exhibit G above) to be paid for the 4
Omni Way Offer  Space and the date on which the 4 Omni Way Offer  Space shall be
available  for  lease  (the "4 Omni Way  Offer  Notice").  Tenant  shall  notify
Landlord in writing  whether  Tenant elects to lease the entire 4 Omni Way Offer
Space on the terms set forth in the 4 Omni Way Offer  Notice,  within  seven (7)
business days after Landlord  delivers to Tenant the 4 Omni Way Offer Notice. If
Tenant  timely  elects to lease the 4 Omni Way Offer  Space,  then  Landlord and
Tenant shall, at Landlord's sole  discretion,  execute a new lease agreement for
the 4 Omni Way Offer Space or an amendment to this Lease within thirty (30) days
after Tenant's election,  effective as of the date the 4 Omni Way Offer Space is
available for lease,  on the terms set forth in the 4 Omni Way Offer Notice and,
to the extent not inconsistent with the 4 Omni Way Offer Notice terms, the terms
of this Lease.

         If Tenant fails or is unable to timely  exercise  its right  hereunder,
then such right  shall  lapse,  time being of the  essence  with  respect to the
exercise  thereof,  and  Landlord  may lease all or a portion  of the 4 Omni Way
Offer   Space  to  third   parties  on  such  terms  as   Landlord   may  elect.
Notwithstanding  the foregoing,  if Landlord  leases less than one-half of the 4
Omni Way Offer Space to a third  party,  Tenant's  right of first offer  granted
under this Exhibit  shall  continue  with respect to the remainder of the 4 Omni
Way Offer Space not leased to such third  party;  provided,  however,  if Tenant
fails or is unable to timely  exercise its rights  hereunder with respect to the
remainder of the 4 Omni Way Offer Space,  then such right to lease the remainder
of the 4 Omni Way Offer  Space  shall  lapse,  time  being of the  essence  with
respect to the exercise thereof,  and Landlord may lease all or a portion of the
remainder  of the 4 Omni  Way  Offer  Space to third  parties  on such  terms as
Landlord may elect.  Further,  but subject to the  provisions  of the  preceding
sentence,  Tenant's right of first offer granted under this Exhibit with respect
to the 4 Omni Way Offer Space shall continue during the initial Term on the same
terms and  conditions  set forth herein to the extent the 4 Omni Way Offer Space
again becomes available during the initial Term.



<PAGE>


         Tenant may not  exercise  its rights  under this Exhibit if an Event of
Default exists,  if Tenant is not then occupying at least  seventy-five  percent
(75%)  of  the  Premises,  or if  Tenant  has a net  worth  that  is  less  than
ninety-five  percent  (95%) of  Tenant's  net worth as of the date  hereof.  For
purposes hereof,  if a 4 Omni Way Offer Notice is delivered for less than all of
the 4 Omni Way Offer Space but such notice  provides for an expansion,  right of
first  refusal,  or other  preferential  right to  lease  some of the  remaining
portion of the 4 Omni Way Offer Space, then such remaining portion of the 4 Omni
Way Offer  Space  shall  thereafter  be  excluded  from the  provisions  of this
Exhibit.

         Tenant's rights under this Exhibit shall terminate if (a) this Lease or
Tenant's right to possession of the Premises is  terminated,  (b) Tenant assigns
any of its interest in this Lease or sublets more than twenty-five percent (25%)
of the Premises, or (c) the initial Term expires.

         Notwithstanding  any  provisions of this Lease to the contrary,  if the
fee title to the 4 Omni Way Offer Space is held by an entity other than Landlord
or any Affiliate of Landlord and such entity fails to comply with the provisions
of this  Exhibit K, Tenant shall have no  recourse,  rights or remedies  against
Landlord if such entity  fails to comply with the  provisions  of this Exhibit K
and Tenant shall continue to comply with the provisions of this Lease.

     Price to be exceeded shall be paid by the Contractor without  reimbursement

     any, which are described in the Contract  Documents and are hereby accepted
     by the  Owner:  (State  the  numbers or other  identification  of  accepted
     alternates.  If decisions on other  alternates  are to be made by the Owner

     require further  development by the Architect,  the Contractor has provided
     in the  Guaranteed  Maximum Price for such further  development  consistent
     with the  Contract  Documents  and  reasonably  inferable  therefrom.  Such
     further  development  does not  include  such  things as  changes in scope,

     which, if required, shall be incorporated by Change Order.

     perform  with the  Contractor's  own  personnel  shall be  performed  under
     subcontracts or by other  appropriate  agreements with the Contractor.  The
     Owner may designate  specific  persons or entities from whom the Contractor
     shall obtain bids. The Contractor shall obtain bids from Subcontractors and
     from suppliers of materials or equipment fabricated especially for the Work
     and  shall  deliver  such  bids to the  Architect.  The  Owner  shall  then
     determine, with the advice of the Contractor and the Architect,  which bids

     Documents  but the Owner  requires  that another bid be accepted,  then the
     Contractor  may  require  that a  Change  Order be  issued  to  adjust  the
     Guaranteed Maximum Price by the difference between the bid of the person or
     entity  recommended  to the Owner by the  Contractor  and the amount of the
     subcontract or other  agreement  actually  signed with the person or entity
     designated by the Owner.

     10.3  Subcontracts  or other  agreements  shall  conform to the  applicable
     payment provisions of this Agreement, and shall not be awarded on the basis
     of cost plus a fee without the prior consent of the Owner.


ARTICLE 11 ACCOUNTING RECORDS
     The  Contractor  shall keep full and detailed  accounts  and exercise  such
     controls as may be necessary  for proper  financial  management  under this
     Contract,  and the accounting and control  systems shall be satisfactory to
     the Owner.  The Owner and the Owner s accountants  shall be afforded access
     to, and shall be permitted  to audit and copy,  the  Contractor's  records,
     books,  correspondence,  instructions,  drawings,  receipts,  subcontracts,
     purchase  orders,  vouchers,  memoranda  and other  data  relating  to this
     Contract,  and the  Contractor  shall  preserve these for a period of three
     years after final payment,  or for such longer period as may be required by
     law.




ARTICLE 12 PAYMENTS
     12.1     PROGRESS PAYMENTS
     12.1.1 Based upon  Applications  for Payment  submitted to the Architect by
     the Contractor and  Certificates  for Payment issued by the Architect,  the
     Owner shall make  progress  payments on account of the  Contract Sum to the
     Contractor as provided below and elsewhere in the Contract Documents.



<PAGE>


     12.1.2 The period  covered by each  Application  for  Payment  shall be one
     calendar month ending on the last day of the month, or as follows:

12.1.3 Provided that an Application for Payment is received by the Architect not
     later than the 25th day of a month,  the Owner  shall  make  payment to the
     Contractor  not  later  than  the 15th day of the  following  month.  If an
     Application  for Payment is received by the Architect after the application
     date fixed above, payment shall be made by the Owner not later than 21 days
     after the Architect receives the Application for Payment.

     12.1.4 With each  Application  for Payment,  the  Contractor  shall submit,
     receipted invoices or invoices with check vouchers attached,  and any other
     evidence  required by the Owner or  Architect.  At the Owner's  request and
     expense, the Contractor shall furnish back-up documentation for the General
     Conditions costs incurred by the Contractor.

     12.1.5  Each  Application  for  Payment  shall be based on the  schedule of
     values  submitted  by  the  Contractor  in  accordance  with  the  Contract
     Documents.  The  schedule of values shall  allocate  the entire  Guaranteed
     Maximum  Price  among the  various  portions  of the Work,  except that the
     Contractor's  Fee shall be shown as a single separate item. The schedule of
     values  shall be  prepared  in such  form  and  supported  by such  data to
     substantiate  its accuracy as the  Architect  may require.  This  schedule,
     unless objected to by the Architect, shall be used as a basis for reviewing
     the Contractor's Applications for Payment.



<PAGE>


         12.1.6 Applications for Payment shall show the percentage of completion
         of each portion of the Work as of the end of the period  covered by the
         Application for Payment.

<PAGE>



     12.1.7 Subject to other provisions of the Contract Documents, the amount of
each progress payment shall be computed as follows:

          .1  take  that  portion  of  the  Guaranteed  Maximum  Price  properly
              allocable to  completed  Work as  determined  by  multiplying  the
              percentage  of completion of each portion of the Work by the share
              of the Guaranteed  Maximum Price  allocated to that portion of the
              Work in the schedule of values.  Pending  final  determination  of
              cost to the Owner of changes in the Work,  amounts  not in dispute
              shall  be  included  as  provided  in  Subparagraph  7.3.8  of AlA
              Document A201-1997;

         .2   add  that  portion  of  the  Guaranteed   Maximum  Price  properly
              allocable to materials and equipment delivered and suitably stored
              at the  site  for  subsequent  incorporation  in the  Work,  or if
              approved in advance by the Owner,  suitably stored off the site at
              a location agreed upon in writing;

         .3   add the  Contractor's  Fee,  less  retainage of Ten percent  (10%)
              provided.  however that the  Contractor's  General  Conditions fee
              shall not be subject to retainage.  The  Contractor's Fee shall be
              computed upon the Cost of the Work  described in the two preceding
              Clauses  at the rate  stated  in  Subparagraph  5.1.2  or,  if the
              Contractor's  Fee is stated  as a fixed sum in that  Subparagraph,
              shall be an amount that bears the same ratio to that fixed-sum fee
              as the Cost of the Work in the two  preceding  Clauses  bears to a
              reasonable  estimate  of the  probable  Cost of the Work  upon its
              completion; Retainage to be 10% until 50% complete: 0% thereafter.
              No retainage on Contractor's fee or General Conditions.

         .4   subtract the aggregate of previous payments made by the Owner;

         .5   subtract the shortfall, if any, indicated by the Contractor in the
              documentation  required by Paragraph 12.1.4 to substantiate  prior
              Applications  for Payment,  or resulting from errors  subsequently
              discovered by the Owner's accountants in such documentation; and

          .6  subtract amounts,  if any, for which the Architect has withheld or
              nullified a  Certificate  for Payment as provided in Paragraph 9.5
              of ALA Document A201-1997.

     12.1.8 Except with the Owner's prior approval,  payments to  Subcontractors
     shall be subject to retainage of not less than Ten percent  (10%) The Owner
     and the  Contractor  shall agree upon a mutually  acceptable  procedure for
     review and approval of payments and retention for Subcontractors.

     12.1.9 In taking action on the Contractor's  Applications for Payment,  the
     Architect shall be entitled to rely on the accuracy and completeness of the
     information  furnished  by  the  Contractor  and  shall  not be  deemed  to
     represent  that the  Architect  has made a detailed  examination,  audit or
     arithmetic  verification of the documentation  submitted in accordance with
     Subparagraph  12.1.4 or other  supporting data; that the Architect has made
     exhaustive or continuous on-site inspections or that the Architect has made
     examinations  to ascertain how or for what purposes the Contractor has used
     amounts  previously  paid on account of the  Contract.  Such  examinations,
     audits and  verifications,  if required by the Owner,  will be performed by
     the Owner's accountants acting in the sole interest of the Owner.

     12.2    FINAL PAYMENT
     12.2.1  Final  payment,  constituting  the  entire  unpaid  balance  of the
     Contract Sum,  together with any shared  savings  amounts due in accordance
     with Subparagraph 5.2.1 shall be made by the Owner to the Contractor when:

              .1  the Contractor has fully performed the Contract except for the
                  Contractor's  responsibility  to correct  Work as  provided in
                  Subparagraph 12.2.2 of ALA Document A201-1997,  and to satisfy
                  other requirements, if any, which extend beyond final payment;
                  and

              .2  a final Certificate for Payment has been issued by the 
                 Architect.

     12.2.2   The Owner's final payment to the Contractor shall be made no later
              than 30 days after the issuance of the Architect's final 
              Certificate for Payment, or as follows:

     12.2.3 The  Owner's  accountants  will  review and report in writing on the
     Contractor's  final  accounting  within 30 days after delivery of the final
     accounting to the Architect by the Contractor.  Based upon such Cost of the
     Work  as  the  Owner's  accountants  report  to  be  substantiated  by  the
     Contractor's  final  accounting,  and  provided  the  other  conditions  of
     Subparagraph  12.2.1 have been met, the Architect  will,  within seven days
     after  receipt of the  written  report of the Owner's  accountants,  either
     issue  to the  Owner a final  Certificate  for  Payment  with a copy to the
     Contractor,   or  notify  the  Contractor  and  Owner  in  writing  of  the
     Architect's   reasons  for   withholding  a  certificate   as  provided  in
     Subparagraph 9.5.1 of the AlA Document  A201-1997.  The time periods stated
     in this Subparagraph 12.2.3 supersede those stated in Subparagraph 9.4.1 of
     the ALA Document A201-1997.

     12.2.4  If  the  Owner's  accountants  report  the  Cost  of  the  Work  as
     substantiated by the Contractor's  final accounting to be less than claimed
     by the Contractor,  the Contractor shall be entitled to demand  arbitration
     of the disputed  amount without a further  decision of the Architect.  Such
     demand for arbitration shall be made by the Contractor within 30 days after
     the Contractor's receipt of a copy of the Architect's final Certificate for
     Payment;  failure to demand  arbitration  within this 30-day  period  shall
     result in the  substantiated  amount  reported by the  Owner's  accountants
     becoming  binding  on  the  Contractor.   Pending  a  final  resolution  by
     arbitration, the Owner shall pay the Contractor the amount certified in the
     Architect's final Certificate for Payment.



     12.2.5 If,  subsequent  to final  payment and at the Owner's  request,  the
     Contractor  incurs costs described in Article 7 and not excluded by Article
     8 to correct defective or nonconforming Work, the Owner shall reimburse the
     Contractor such costs and the  Contractor's  Fee applicable  thereto on the
     same basis as if such costs had been incurred prior to final  payment,  but
     not in  excess of the  Guaranteed  Maximum  Price.  If the  Contractor  has
     participated  in savings as provided in  Paragraph  5.2, the amount of such
     savings shall be recalculated and appropriate  credit given to the Owner in
     determining the net amount to be paid by the Owner to the Contractor.


ARTICLE 13 TERMINATION OR SUSPENSION
     13.1 The Contract may be terminated by the Contractor,  or by the Owner for
     convenience, as provided in Article 14 of ALA Document A201-1997.  However,
     the amount to be paid to the Contractor  under  Subparagraph  14.1.3 of ALA
     Document  A201-1997  shall not exceed the  amount the  Contractor  would be
     entitled to receive under Paragraph 13.2 below, except that the



<PAGE>


     Contractor's  Fee  shall  be  calculated  as if the  Work  had  been  fully
     completed by the Contractor, including a reasonable estimate of the Cost of
     the Work for Work not actually completed.

     13.2 The Contract may be  terminated  by the Owner for cause as provided in
     Article 14 of AlA  Document A20 1-1997.  The amount,  if any, to be paid to
     the Contractor under  Subparagraph  14.2.4 of AlA Document  A201-1997 shall
     not cause the Guaranteed Maximum Price to be exceeded,  nor shall it exceed
     an amount calculated as follows:

     13.2.1   Take the Cost of the Work incurred by the Contractor to the date
     of termination;

     13.2.2 Add the  Contractor's  Fee computed upon the Cost of the Work to the
     date of  termination  at the rate stated in  Subparagraph  5.1.2 or, if the
     Contractor's Fee is stated as a fixed sum in that  Subparagraph,  an amount
     that bears the same ratio to that  fixed-sum Fee as the Cost of the Work at
     the time of termination bears to a reasonable estimate of the probable Cost
     of the Work upon its completion; and

     13.2.3 Subtract the aggregate of previous payments made by the Owner.

     13.3 The Owner shall also pay the Contractor fair  compensation,  either by
     purchase or rental at the election of the Owner, for any equipment owned by
     the  Contractor  that the Owner elects to retain and that is not  otherwise
     included in the Cost of the Work under  Subparagraph  13.2.1. To the extent
     that the Owner elects to take legal assignment of subcontracts and purchase
     orders (including rental agreements),  the Contractor shall, as a condition
     of  receiving  the  payments  referred to in this  Article 13,  execute and
     deliver  all such  papers  and take all such  steps,  including  the  legal
     assignment  of  such  subcontracts  and  other  contractual  rights  of the
     Contractor,  as the Owner may require  for the purpose of fully  vesting in
     the Owner the rights and benefits of the Contractor under such subcontracts
     or purchase orders.

     13.4 The Work may be  suspended  by the Owner as  provided in Article 14 of
     AlA Document  A201-1997;  in such case,  the  Guaranteed  Maximum Price and
     Contract Time shall be increased as provided in Subparagraph  14.3.2 of ALA
     Document A20 1-1997  except that the term  "profit"  shall be understood to
     mean the Contractor's Fee as described in Subparagraphs 5.1.2 and Paragraph
     6.4 of this Agreement.


ARTICLE 14 MISCELLANEOUS PROVISIONS

     ARTICLE I GENERAL PROVISIONS
     1.1  BASIC DEFINITIONS
     1.1.1    THE CONTRACT DOCUMENTS
     The  Contract   Documents  consist  of  the  Agreement  between  Owner  and
     Contractor   (hereinafter  the  Agreement),   Conditions  of  the  Contract
     (General,  Supplementary and other Conditions),  Drawings,  Specifications,
     Addenda issued prior to execution of the Contract,  other documents  listed
     in the Agreement and Modifications  issued after execution of the Contract.
     A Modification  is (1) a written  amendment to the Contract  signed by both
     parties,  (2) a Change Order, (3) a Construction  Change Directive or (4) a
     written  order  for a minor  change in the Work  issued  by the  Architect.
     Unless specifically enumerated in the Agreement,  the Contract Documents do
     not include other documents such as bidding requirements  (advertisement or
     invitation to bid, Instructions to Bidders,  sample forms, the Contractor's
     bid or portions of Addenda relating to bidding requirements).

     1.1.2    THE CONTRACT
     The Contract  Documents  form the Contract for  Construction.  The Contract
     represents the entire and integrated  agreement  between the parties hereto
     and supersedes prior  negotiations,  representations or agreements,  either
     written  or  oral.  The  Contract  may be  amended  or  modified  only by a
     Modification.  The  Contract  Documents  shall not be construed to create a
     contractual  relationship  of  any  kind  (1)  between  the  Architect  and
     Contractor, (2) between the Owner and a Subcontractor or Sub-subcontractor,
     (3) between the Owner and  Architect or (4) between any persons or entities
     other than the Owner and  Contractor.  The  Architect  shall,  however,  be
     entitled to performance and  enforcement of obligations  under the Contract
     intended to facilitate performance of the Architect's duties.

     1.1.3    THE WORK
     The term  "Work"  means  the  construction  and  services  required  by the
     Contract Documents,  whether completed or partially completed, and includes
     all other  labor,  materials,  equipment  and  services  provided  or to be
     provided by the  Contractor to fulfill the  Contractor's  obligations.  The
     Work may constitute the whole or a part of the Project.

     1.1.4     THE PROJECT
     The Project is the total construction of which the Work performed under the
     Contract  Documents  may be the  whole  or a part  and  which  may  include
     construction by the Owner or by separate contractors.

     1.1.5    THE DRAWINGS
     The  Drawings  are the  graphic  and  pictorial  portions  of the  Contract
     Documents  showing  the  design,  location  and  dimensions  of  the  Work,
     generally including plans,  elevations,  sections,  details,  schedules and
     diagrams.

     1.1.6    THE SPECIFICATIONS
     The Specifications are that portion of the Contract Documents consisting of
     the written requirements for materials,  equipment,  systems, standards and
     workmanship for the Work, and performance of related services.

     1.1.7    THE PROJECT MANUAL
     The Project Manual is a volume assembled for the Work which may include the
     bidding  requirements,   sample  forms,  Conditions  of  the  Contract  and
     Specifications.

     1.2  CORRELATION AND INTENT OF THE CONTRACT DOCUMENTS
     1.2.1  The  intent  of the  Contract  Documents  is to  include  all  items
     necessary  for the  proper  execution  and  completion  of the  Work by the
     Contractor. The Contract Documents are complementary,  and what is required
     by one  shall be as  binding  as if  required  by all;  performance  by the
     Contractor  shall  be  required  only to the  extent  consistent  with  the
     Contract Documents and reasonably inferable from them as being necessary to
     produce the indicated results.

     1.2.2  Organization  of the  Specifications  into  divisions,  sections and
     articles,  and  arrangement of Drawings shall not control the Contractor in
     dividing the Work among  Subcontractors  or in  establishing  the extent of
     Work to be performed by any trade.


      1.2.3 Unless otherwise stated in the Contract Documents,  words which have
     well-known  technical  or  construction  industry  meanings are used in the
     Contract Documents in accordance with such recognized meanings.

     1.3  CAPITALIZATION
     1.3.1 Terms capitalized in these General Conditions include those which are
(1) specifically defined, (2) the titles of


<PAGE>


     numbered  articles and identified  references to Paragraphs,  Subparagraphs
     and Clauses in the document or (3) the titles of other documents  published
     by the American Institute of Architects.

     1.4 INTERPRETATION

     1.4.1 In the interest of brevity the  Contract  Documents  frequently  omit
     modifying  words  such as "all" and "any"  and  articles  such as "the" and
     "an,"  but the fact  that a  modifier  or an  article  is  absent  from one
     statement   and   appears  in  another  is  not   intended  to  affect  the
     interpretation of either statement.

     1.5 EXECUTION OF CONTRACT DOCUMENTS

     1.5.1 The Contract  Documents  shall be signed by the Owner and Contractor.
     If either  the  Owner or  Contractor  or both do not sign all the  Contract
     Documents,  the  Architect  shall  identify such  unsigned  Documents  upon
     request.

     1.5.2 Execution of the Contract by the Contractor is a representation  that
     the Contractor has visited the site,  become generally  familiar with local
     conditions under which the Work is to be performed and correlated  personal
     observations with requirements of the Contract Documents.  Execution of the
     Contract by the Owner is a representation  that the Owner has made adequate
     arrangements  to fund  the  Project  and has  performed  or  fulfilled  any
     requirements or conditions for commencement of the Project except for those
     requirements   and   conditions   which  by  the  terms   hereof   are  the
     responsibility of the Contractor.

     1.6  OWNERSHIP AND USE OF DRAWINGS, SPECIFICATIONS AND OTHER INSTRUMENTS 
     OF SERVICE
     1.6.1 The Drawings,  Specifications and other documents, including those in
     electronic form, prepared by the Architect and the Architect's  consultants
     are  Instruments  of Service  through  which the Work to be executed by the
     Contractor is described.  The Contractor may retain one record set. Neither
     the  Contractor  nor any  Subcontractor,  Sub-subcontractor  or material or
     equipment  supplier  shall  own or  claim  a  copyright  in  the  Drawings,
     Specifications  and  other  documents  prepared  by  the  Architect  or the
     Architect's  consultants,  and unless otherwise indicated the Architect and
     the  Architect's  consultants  shall be deemed the authors of them and will
     retain all common law,  statutory and other reserved rights, in addition to
     the  copyrights.   All  copies  of  Instruments  of  Service,   except  the
     Contractor's record set, shall be returned or suitably accounted for to the
     Architect,   on  request,  upon  completion  of  the  Work.  The  Drawings,
     Specifications  and  other  documents  prepared  by the  Architect  and the
     Architect's  consultants,  and copies thereof  furnished to the Contractor,
     are for use solely with respect to this Project. They are not to be used by
     the  Contractor  or any  Subcontractor,  Sub-subcontractor  or  material or
     equipment  supplier on other  projects  or for  additions  to this  Project
     outside the scope of the Work without the specific  written  consent of the
     Owner,   Architect  and  the  Architect's   consultants.   The  Contractor,
     Subcontractors,  Sub-subcontractors and material or equipment suppliers are
     authorized  to use  and  reproduce  applicable  portions  of the  Drawings,
     Specifications  and  other  documents  prepared  by the  Architect  and the
     Architect's  consultants  appropriate  to and for use in the  execution  of
     their  Work  under the  Contract  Documents.  All  copies  made  under this
     authorization  shall bear the statutory  copyright notice, if any, shown on
     the Drawings,  Specifications and other documents prepared by the Architect
     and the Architect's consultants. Submittal or distribution to meet official
     regulatory  requirements  or for other  purposes  in  connection  with this
     Project  is  not  to be  construed  as  publication  in  derogation  of the
     Architect's  or  Architect's  consultants'  copyrights  or  other  reserved
     rights.

     the Work under the Owner's  control  shall be  furnished by the Owner after
     receipt from the  Contractor of a written  request for such  information or
     services and within the period of time reasonably requested.

     2.2.5 Unless otherwise provided in the Contract  Documents,  the Contractor

     Manuals as are reasonably necessary for execution of the Work.

     2.3 OWNER'S RIGHT TO STOP THE WORK
     2.3.1 If the  Contractor  fails to correct Work which is not in  accordance
     with the  requirements  of the Contract  Documents as required by Paragraph
     12.2 or  persistently  fails  to  carry  out  Work in  accordance  with the
     Contract  Documents,  the Owner may issue a written order to the Contractor
     to stop the Work,  or any portion  thereof,  until the cause for such order
     has been eliminated; however, the right of the Owner to stop the Work shall
     not give rise to a duty on the part of the Owner to exercise this right for
     the benefit of the Contractor or any other person or entity,  except to the
     extent required by Subparagraph 6.1.3.


     2.4 OWNERS RIGHT TO CARRY OUT THE WORK
     2.4.1 If the  Contractor.  defaults  or  neglects  to carry out the Work in
     accordance with the Contract  Documents and fails within a seven-day period
     after  receipt of written  notice from the Owner to commence  and  continue
     correction of such default or neglect with  diligence and  promptness,  the
     Owner may after such seven-day  period give the Contractor a second written
     notice  to  correct  such  deficiencies  within  seven-day  period.  If the
     Contractor within such seven-day period after receipt of such second notice
     fails to commence and continue to correct any deficiencies,  the Owner may,
     without  prejudice  to other  remedies  the Owner may  have,  correct  such
     deficiencies.  In such case an  appropriate  Change  Order  shall be issued
     deducting   from  payments  then  or  thereafter  due  the  Contractor  the
     reasonable cost of correcting such deficiencies, including Owner s expenses
     and compensation for the Architect's  additional services made necessary by
     such  default,  neglect or  failure.  Such  action by the Owner and amounts
     charged  to the  Contractor  are  both  subject  to prior  approval  of the
     Architect.  If  payments  then or  thereafter  due the  Contractor  are not
     sufficient to cover such amounts,  the Contractor  shall pay the difference
     to the Owner.


ARTICLE 3 CONTRACTOR
     3.1  GENERAL
     3.1.1 The  Contractor  is the  person or entity  identified  as such in the
     Agreement  and is referred  to  throughout  the  Contract  Documents  as if
     singular  in number.  The term  "Contractor"  means the  Contractor  or the
     Contractor's authorized representative.


     3.1.2 The Contractor shall perform the Work in accordance with the Contract
Documents.

     3.1.3 The  Contractor  shall not be relieved of  obligations to perform the
     Work in accordance  with the Contract  Documents by activities or duties of
     the Architect in the Architect's  administration of the Contract, but shall
     be  entitled  to rely upon  tests,  inspections  or  approvals  required or
     performed by the Architect, Owner, or consultants of either of them.


     3.2 REVIEW OF CONTRACT DOCUMENTS AND FIELD CONDITIONS BY CONTRACTOR
     3.2.1 Since the Contract Documents are complementary,  before starting each
     portion of the Work, the Contractor  shall  carefully study and compare the
     various Drawings and other Contract  Documents  relative to that portion of
     the Work, as well as
    the information furnished by the Owner pursuant to Subparagraph 2.2.3, shall
    take field  measurements of any existing  conditions related to that portion
    of the Work and shall observe any conditions at the site affecting it. These
    obligations  are  for  the  purpose  of  facilitating  construction  by  the
    Contractor and are not for the purpose of discovering errors,  omissions, or
    inconsistencies   in  the   Contract   Documents;   however,   any   errors,
    inconsistencies or omissions  discovered by the Contractor shall be reported
    promptly to the Architect as a request for  information  in such form as the
    Architect may require.

     3.2.2 Any design errors or omissions  noted by the  Contractor  during this
     review shall be reported  promptly to the  Architect,  but it is recognized
     that the  Contractor's  review is made in the  Contractor's  capacity  as a
     contractor  and not as a  licensed  design  professional  unless  otherwise
     specifically  provided in the Contract  Documents.  The  Contractor  is not
     required to ascertain  that the Contract  Documents are in accordance  with
     applicable  laws,  statutes,  ordinances,  building  codes,  and  rules and
     regulations,  but any  nonconformity  discovered  by or made  known  to the
     Contractor shall be reported promptly to the Architect.

     3.2.3 If the Contractor  believes that  additional cost or time is involved
     because  of  clarifications  or  instructions  issued by the  Architect  in
     response to the Contractor's  notices or requests for information  pursuant
     to  Subparagraphs  3.2.1 and 3.2.2,  the  Contractor  shall make  Claims as
     provided  in  Subparagraphs  4.3.6 and  4.3.7.  If the  Contractor  without
     justification  fails to perform the obligations of Subparagraphs  3.2.1 and
     3.2.2,  the  Contractor  shall pay such  costs and  damages to the Owner as
     would have been avoided if the Contractor  had performed such  obligations.
     The  Contractor  shall not be liable to the Owner or Architect  for damages
     resulting  from  errors,  inconsistencies  or  omissions  in  the  Contract
     Documents or for differences  between field  measurements or conditions and
     the  Contract  Documents  unless  the  Contractor  recognized  such  error,
     inconsistency,  omission or difference and knowingly failed to report it to
     the Architect.

     techniques,  sequences and procedures and for  coordinating all portions of
     the Work under the  Contract,  unless  the  Contract  Documents  give other
     specific  instructions  concerning these matters. If the Contract Documents
     give  specific   instructions   concerning   construction  means,  methods,
     techniques,  sequences or  procedures,  the  Contractor  shall evaluate the
     jobsite  safety  thereof and,  except as stated  below,  shall be fully and
     solely  responsible  for  the  jobsite  safety  of  such  means,   methods,
     techniques, sequences or procedures. If the Contractor determines that such
     means,  methods,  techniques,  sequences or procedures may not be safe, the
     Contractor  shall give timely written notice to the Owner and Architect and
     shall not proceed  with that portion of the Work  without  further  written
     instructions  from the Architect.  If the Contractor is then  instructed to
     proceed  with  the  required  means,  methods,  techniques,   sequences  or
     procedures  without  acceptance of changes proposed by the Contractor,  the
     Architect9wnea~-shall  be  solely  responsible  for any  resulting  loss or
     damage.

     execution of the Work.

     3.10.2 The Contractor  shall prepare and keep current,  for the Architect's
     approval,   a  schedule  of  submittals   which  is  coordinated  with  the

     similar  submittals,  the  Contractor  represents  that the  Contractor has
     determined   and  verified   materials,   field   measurements   and  field
     construction  criteria related thereto,  or will do so, and has checked and
     coordinated  the  information  contained  within such  submittals  with the
     requirements of the Work and of the Contract Documents.

     3.12.7 The  Contractor  shall  perform no portion of the Work for which the
     Contract  Documents require submittal and review of Shop Drawings,  Product
     Data, Samples or similar submittals until the respective submittal has been

     the Contractor shall not be relieved of responsibility  for deviations from
     requirements of the Contract Documents by the Architect's  approval of Shop
     Drawings, Product Data, Samples or similar submittals unless the Contractor
     has specifically informed the Architect in writing of such deviation at the
     time of submittal and (I) the  Architect has given written  approval to the
     specific  deviation as a minor change in the Work, or (2) the Architect has
     with knowledge of any deviation  approved such  submittal,  or (3) a Change
     Order or  Construction  Change  Directive has been issued  authorizing  the
     deviation.  The  Contractor  shall not be  relieved of  responsibility  for
     errors or  omissions in Shop  Drawings,  Product  Data,  Samples or similar
     submittals by the Architect's approval thereof.

     resubmitted Shop Drawings,  Product Data, Samples or similar submittals, to
     revisions   other  than  those  requested  by  the  Architect  on  previous
     submittals.  In the absence of such written notice the Architect's approval
     of a resubmission shall not apply to such revisions.

    3.12.10  The  Contractor  shall  not be  required  to  provide  professional
    services which constitute the practice of architecture or engineering unless
    such  services are  specifically  required by the Contract  Documents  for a
    portion of the Work or unless the Contractor  needs to provide such services
    in order to carry out the  Contractor's  responsibilities  for  construction
    means, methods,  techniques,  sequences and procedures. The Contractor shall
    not be required to provide professional  services in violation of applicable
    law.  If  professional   design  services  or  certifications  by  a  design
    professional  related to systems,  materials or equipment  are  specifically
    required of the  Contractor  by the  Contract  Documents,  the Owner and the
    Architect  will  specify  all  performance  and  design  criteria  that such
    services must satisfy.  The Architect,  upon  completion of the Drawings and
    Specifications, shall notify the Owner and Contractor of all items for which
    the Contract  Documents  require the Contractor to furnish  architecture  or
    engineering  services.  -  The  Contractor  shall  cause  such  services  or
    certifications  to be provided by a properly  licensed design  professional,
    whose  signature  and  seal  shall  appear  on all  drawings,  calculations,
    specifications,  certifications, Shop Drawings and other submittals prepared
    by such professional. Shop Drawings and other submittals related to the Work
    designed or certified  by such  professional,  if prepared by others,  shall
    bear such  professional's  written approval when submitted to the Architect.
    The Owner and the  Architect  shall be entitled  to rely upon the  adequacy,
    accuracy  and  completeness  of the  services,  certifications  or approvals
    performed by such design  professionals,  provided  the Owner and  Architect
    have specified to the Contractor all  performance  and design  criteria that
    such services  must  satisfy.  Pursuant to this  Subparagraph  3.12.10,  the
    Architect  will  review,   approve  or  take  other  appropriate  action  on
    submittals  only for the limited  purpose of checking for  conformance  with
    information   given  and  the  design  concept  expressed  in  the  Contract
    Documents- and for coordination with other applicable  design elements.  The
    Contractor  shall not be responsible  for the adequacy of the performance or
    design criteria required by the Contract Documents.

     3.13     USE OF SITE
    3.13.1  The  Contractor  shall  confine  operations  at the  site  to  areas

     contractors by cutting,  patching or otherwise  altering such construction,
     or by  excavation.  The  Contractor  shall not cut or otherwise  alter such
     construction  by the Owner or a separate  contractor  except  with  written
     consent of the Owner and of such  separate  contractor;  such consent shall
     not  be  unreasonably  withheld.  The  Contractor  shall  not  unreasonably
     withhold from the Owner or a separate  contractor the Contractor's  consent
     to cutting or otherwise altering the Work.

     3.15     CLEANING UP
     3.15.1 The  Contractor  shall keep the premises and  surrounding  area free
     from  accumulation of waste materials or rubbish caused by operations under
     the Contract.  At completion of the Work, the Contractor  shall remove from
     and about the Project waste materials,  rubbish,  the  Contractor's  tools,
     construction equipment, machinery and surplus materials.

     manufacturers is required by the Contract  Documents or where the copyright
     violations  are contained in Drawings,  Specifications  or other  documents
     prepared by the Owner or Architect.  However,  if the Contractor has reason
     to believe that the required design,  process or product is an infringement
     of a copyright or a patent,  the Contractor  shall be responsible  for such
     loss unless such information is promptly furnished to the Architect.

     3.18     INDEMNIFICATION
     3.18.1 To the fullest  extent  permitted  by law and to the extent  claims,
     damages, losses or expenses are not covered by Commercial General Liability
     insurance  purchased by the Contractor in accordance  with Paragraph  11.3,
     the  Contractor  shall  indemnify and hold  harmless the Owner,  Architect,
     Architect's  consultants,  and agents and employees of any of them from and
     against claims, damages, losses and expenses,  including but not limited to
     attorneys' fees,  arising out of or resulting from performance of the Work,
     provided that such claim, damage, loss or expense is attributable to bodily
     injury,  sickness,  disease  or death,  or to injury to or  destruction  of
     tangible  property  (other  than the Work  itself),  but only to the extent
     caused  by  the  negligent   acts  or  omissions  of  the   Contractor,   a
     Subcontractor, anyone directly or indirectly employed by them or anyone for
     whose acts they may be  liable,  regardless  of whether or not such  claim,
     damage, loss or expense is caused in part by a party indemnified hereunder.
     Such obligation shall not be construed to negate,  abridge, or reduce other
     rights or  obligations  of indemnity  which would  otherwise  exist as to a
     party or person described in this Paragraph 3.18.

     3.18.2 In claims  against  any  person or  entity  indemnified  under  this

ARTICLE 4 ADMINISTRATION OF THE CONTRACT
     4.1 ARCHITECT
     4.1.1  The   Architect  is  the  person   lawfully   licensed  to  practice
     architecture or an entity lawfully  practicing  architecture  identified as
     such in the Agreement and is referred to throughout the Contract  Documents
     as if singular in number.  The term "Architect"  means the Architect or the
     Architect's authorized representative.

     4.1.2  Duties,   responsibilities  and  limitations  of  authority  of  the
     Architect as set forth in the Contract  Documents  shall not be restricted,
     modified or extended  without written consent of the Owner,  Contractor and
     Architect. Consent shall not be unreasonably withheld.

     4.1.3 If the  employment  of the Architect is  terminated,  the Owner shall
     employ a new  Architect  against  whom  the  Contractor  has no  reasonable
     objection  and whose status under the Contract  Documents  shall be that of
     the former Architect.

     4.2 ARCHITECT'S ADMINISTRATION OF THE CONTRACT
     4.2.1  The  Architect  will  provide  administration  of  the  Contract  as
     described in the Contract Documents,  and will be an Owner's representative
     (1) during  construction,  (2) until final  payment is due and (3) with the
     Owner's  concurrence,  from time to time  during  the  one-year  period for
     correction of Work  described in Paragraph  12.2.  The Architect  will have
     authority to act on behalf of the Owner only to the extent  provided in the
     Contract Documents, unless otherwise modified in writing in accordance with
     other provisions of the Contract.

     4.2.2 The Architect,  as a representative of the Owner, will visit the site
     at intervals appropriate to the stage of the Contractor's operations (1) to
     become  generally  familiar with and to keep the Owner  informed  about the
     progress and quality of the portion of the Work completed,  (2) to endeavor
     to guard the Owner against defects and deficiencies in the Work, and (3) to
     determine in general if the Work is being performed in a manner  indicating
     that  the  Work,  when  fully  completed,  will be in  accordance  with the
     Contract  Documents.  However,  the Architect  will not be required to make
     exhaustive or continuous on-site inspections to


<PAGE>


    check the quality or quantity of the Work.  The Architect  will neither have
    control over or charge of, nor be responsible for, the  construction  means,
    methods, techniques,  sequences or procedures, or for the safety precautions
    and  programs  in  connection  with the Work,  since  these are  solely  the
    Contractor's  rights  and  responsibilities  under the  Contract  Documents,
    except as provided in Subparagraph 3.3.1.

    4.2.3 The Architect will not be responsible for the Contractor's  failure to
    perform  the  Work in  accordance  with  the  requirements  of the  Contract
    Documents.  except  where  such  failure  is due  to a  directive  from  the
    Architect.  . The Architect will not have control over or charge of and will
    not be responsible for acts or omissions of the Contractor,  Subcontractors,
    or their agents or employees,  or any other  persons or entities  performing
    portions of the Work.

    4.2.4  Communications   Facilitating  Contract  Administration.   Except  as
    otherwise provided in the Contract  Documents or when direct  communications
    have been specially  authorized,  the Owner and Contractor shall endeavor to
    communicate  with each other  through  the  Architect  or shall  provide the
    Architect  with  contemporaneous  conies of any such direct  communications.
    about matters arising out of or relating to the Contract.  Communications by
    and  with  the  Architect's  consultants  shall be  through  the  Architect.
    Communications by and with  Subcontractors  and material  suppliers shall be
    through the  Contractor.  Communications  by and with  separate  contractors
    shall be through the Owner.

    4.2.5 Based on the Architect's evaluations of the Contractor's  Applications
    for  Payment,  the  Architect  will  review and  certify the amounts due the
    Contractor and will issue Certificates for Payment in such amounts.

     4.2.6 The  Architect  will  have  authority  to  reject  Work that does not
     conform to the  Contract  Documents.  Whenever the  Architect  considers it
     necessary  or  advisable,  the  Architect  will have  authority  to require
     inspection or testing of the Work in accordance with  Subparagraphs  13.5.2
     and 13.5.3, whether or not such Work is fabricated, installed or completed.
     However,  neither this  authority of the  Architect  nor a decision made in
     good faith either to exercise or not to exercise such authority  shall give
     rise  to a duty  or  responsibility  of the  Architect  to the  Contractor,
     Subcontractors,   material  and  equipment   suppliers,   their  agents  or
     employees, or other persons or entities performing portions of the Work.

    4.2.7 The Architect will review and approve or take other appropriate action
    upon the  Contractor's  submittals  such as Shop Drawings,  Product Data and
    Samples,  but only for the limited purpose of checking for conformance  with
    information   given  and  the  design  concept  expressed  in  the  Contract
    Documents.  The  Architect's  action  will be  taken  with  such  reasonable
    promptness  as to cause no  delay  in the Work or in the  activities  of the
    Owner, Contractor or separate contractors, while allowing sufficient time in
    the Architect's  professional  judgment to permit adequate review. Review of
    such submittals is not conducted for the purpose of determining the accuracy
    and completeness of other details such as dimensions and quantities,  or for
    substantiating  instructions for installation or performance of equipment or
    systems,  all of  which  remain  the  responsibility  of the  Contractor  as
    required  by  the  Contract   Documents.   The  Architect's  review  of  the
    Contractor's  submittals shall not relieve the Contractor of the obligations
    under  Paragraphs  3.3,  3.5 and  3.12.  The  Architect's  review  shall not
    constitute approval of safety precautions or, unless otherwise  specifically
    stated by the Architect,  of any construction  means,  methods,  techniques,
    sequences or procedures.  The Architect's  approval of a specific item shall
    not indicate approval of an assembly of which the item is a component.

     4.2.8 The  Architect  will prepare  Change Orders and  Construction  Change
     Directives,  and may  authorize  minor  changes in the Work as  provided in
     Paragraph 7.4.

     4.2.9 The Architect will conduct inspections to determine the date or dates
     of Substantial  Completion and the date of final  completion,  will receive
     and  forward to the Owner,  for the  Owner's  review and  records,  written
     warranties and related documents  required by the Contract and assembled by
     the  Contractor,  and  will  issue a final  Certificate  for  Payment  upon
     compliance with the requirements of the Contract Documents.

     4.2.10 If the Owner and Architect  agree, the Architect will provide one or
     more  project  representatives  to assist in carrying  out the  Architect's
     responsibilities at the site. The duties,  responsibilities and limitations
     of authority of such  project  representatives  shall be as set forth in an
     exhibit to be incorporated in the Contract Documents.

     4.2.11  The  Architect  will   interpret  and  decide  matters   concerning
     performance  under, and requirements of, the Contract  Documents on written
     request of either the Owner or Contractor. The Architect's response to such
     requests  will be made in writing  within any time  limits  agreed  upon or
     otherwise with  reasonable  promptness.  If no agreement is made concerning
     the time within which  interpretations  required of the Architect  shall be
     furnished in compliance  with this  Paragraph  4.2, then delay shall not be
     recognized  on  account  of  failure  by  the  Architect  to  furnish  such
     interpretations until 15 days after written request is made for them.
<PAGE>

    4.2.12  Interpretations  and decisions of the  Architect  will be consistent
    with the intent of and reasonably  inferable from the Contract Documents and
    will  be  in  writing  or  in  the  form  of  drawings.   When  making  such
    interpretations and initial decisions, the Architect will endeavor to secure
    faithful performance by both Owner and Contractor,  will not show partiality
    to either and will not be liable for results of interpretations or decisions
    so rendered in good faith.

    4.2.13 The  Architect's  decisions on matters  relating to aesthetic  effect
    will be final  if  consistent  with the  intent  expressed  in the  Contract
    Documents.

     4.3 CLAIMS AND DISPUTES
    4.3.1  Definition.  A Claim is a demand or  assertion  by one of the parties
    seeking,  as a matter of right,  adjustment  or  interpretation  of Contract
    terms,  payment of money,  extension of time or other relief with respect to
    the terms of the Contract. The term "Claim" also includes other disputes and
    matters in  question  between  the Owner and  Contractor  arising  out of or
    relating to the Contract.  Claims must be initiated by written  notice.  The
    responsibility  to substantiate  Claims shall rest with the party making the
    Claim.

     4.3.2 Time  Limits on  Claims.  Claims by either  party  must be  initiated
     within 21 days after  occurrence  of the event giving rise to such Claim or
     within 21 days after the claimant  first  recognizes  the condition  giving
     rise to the Claim, whichever is later.
     Claims must be initiated by written  notice to the  Architect and the other
party.

     4.3.3 Continuing Contract Performance.  Pending final resolution of a Claim
     except as otherwise agreed in writing or as provided in Subparagraph  9.7.1
     and Article 14, the Contractor shall proceed diligently with performance of
     the Contract and the Owner shall  continue to make  payments in  accordance
     with the Contract Documents.

     4.3.4  Claims  for  Concealed  or Unknown  Conditions.  If  conditions  are
     encountered  at the site which are (1)  subsurface  or Otherwise  concealed
     physical  conditions  which differ  materially  from those indicated in the
     Contract Documents or (2) unknown Physical conditions of an unusual nature,
     which differ  materially from those ordinarily found to exist and generally
     recognized as inherent in construction activities of the character provided
     for in the Contract Documents,  then notice by the observing party Shall be
     given to the other party promptly before conditions are disturbed and in no
     event  later than 21 days after first  observance  Of the  conditions.  The
     Architect will promptly  investigate  such  conditions  and, if they differ
     materially and cause an increase or

     Decrease in the Contractor's cost of, or time required for,  performance of
     any  part of the  Work,  will  recommend  an  equitable  adjustment  in the
     Contract  Sum or  Contract  Time,  or  both.  Claims  by  either  party  in
     opposition  to such  determination  must be made  within 21 days  after the
     Architect has given notice of the decision. If the conditions

     Encountered  are materially  different,  the Contract Sum and Contract Time
     shall be equitably  adjusted,  but if the Owner and Contractor cannot agree
     on an adjustment in the Contract Sum or Contract Time, the adjustment shall
     be determined in accordance with sub-paragraph 7.3.6.


<PAGE>



    4.3.5 Claims for Additional Cost. If the Contractor wishes to make Claim for
    an increase in the Contract Sum,  written notice as provided herein shall be
    given before  proceeding  to execute the Work.  Prior notice is not required
    for Clams  relating to an  emergency  endangering  life or property  arising
    under Paragraph 10.6.

    4.3.6 If the  Contractor  believes  additional  cost is involved for reasons
    including  but  not  limited  to  (1)  a  written  interpretation  from  the
    Architect,  (2) an order by the Owner to stop the Work where the  Contractor
    was not at fault,  (3) a written order for a minor change in the Work issued
    by the Architect,  (4) failure of payment by the Owner,  (5)  termination of
    the Contract by the Owner,  (6) Owner's  suspension or (7) other  reasonable
    grounds, Claim shall be filed in accordance with this Paragraph 4.3.

     4.3.7    Claims for Additional Time
    4.3.7.1  If the  Contractor  wishes  to make  Claim for an  increase  in the
    Contract  Time,  written  notice as  provided  herein  shall be  given.  The
    Contractor's  Claim shall include an estimate of cost and of probable effect
    of delay on  progress  of the Work  where  such  estimate  and effect can be
    reasonably  estimated  at the time of  making  the  claim.  In the case of a
    continuing delay only one Claim is necessary.



<PAGE>


    4.3.7.2  If  adverse  weather  conditions  are the  basis  for a  Claim  for
    additional time, such Claim shall be documented by data  substantiating that
    weather  conditions were abnormal for the period of time, and had an adverse
    effect on the scheduled construction.

    4.3.8  Injury  or  Damage to  Person  or  Property.  If either  party to the
    Contract suffers injury or damage to person or property because of an act or
    omission  of the other  party,  or of others  for whose  acts such  party is
    legally responsible, written notice of such injury or damage, whether or not
    insured,  shall be given to the other  party  within a  reasonable  time not
    exceeding  21 days after  discovery.  The notice  shall  provide  sufficient
    detail to enable the other party to investigate the matter.

    4.3.9 If unit prices are stated in the Contract  Documents  or  subsequently
    agreed  upon,  and if  quantities  originally  contemplated  are  materially
    changed in a proposed Change Order or Construction  Change Directive so that
    application  of such unit prices to  quantities  of Work proposed will cause
    substantial inequity to the Owner or Contractor,  the applicable unit prices
    shall be equitably adjusted.

    4.3.10 Claims for  Consequential  Damages.  The  Contractor  and Owner waive
    Claims  against  each  other for  consequential  damages  arising  out of or
    relating to this Contract. This mutual waiver includes:

             .1  damages incurred by the Owner for rental  expenses,  for losses
                 of use, income, profit, financing, business and reputation, and
                 for  loss of  management  or  employee  productivity  or of the
                 services of such persons; and

             .2  damages   incurred  by  the  Contractor  for  principal  office
                 expenses  including  the  compensation  of personnel  stationed
                 there,  for losses of financing,  business and reputation,  and
                 for loss of profit except  anticipated  profit arising directly
                 from the Work.

    This mutual waiver is applicable,  without limitation,  to all consequential
    damages due to either  party's  termination  in accordance  with Article 14.
    Nothing contained in this Subparagraph 4.3.10 shall be deemed to preclude an
    award of liquidated direct damages, when applicable,  in accordance with the
    requirements of the Contract Documents.

     4.4 RESOLUTION OF CLAIMS AND DISPUTES

     4.4.1 Decision of Architect.  Claims,  including those alleging an error or
     omission by the Architect but excluding those arising under Paragraphs 10.3
     through 10.5, shall be referred initially to the Architect for decision. An
     initial  decision  by  the  Architect  shall  be  required  as a  condition
     precedent to mediation, arbitration or litigation of all Claims between the
     Contractor and Owner arising prior to the date final payment is due, unless
     30 days have passed after the Claim has been referred to the Architect with
     no decision  having been rendered by the Architect.  The Architect will not
     decide  disputes  between the Contractor and persons or entities other than
     the Owner.

    4.4.2 The Architect will review Claims and within ten days of the receipt of
    the Claim take one or more of the following actions:  (1) request additional
    supporting  data from the claimant or a response with  supporting  data from
    the other party,  (2) reject the Claim in whole or in part,  (3) approve the
    Claim,  (4)  suggest  a  compromise,  or (5)  advise  the  parties  that the
    Architect is unable to resolve the Claim if the Architect  lacks  sufficient
    information  to  evaluate  the  merits  of the  Claim  or if  the  Architect
    concludes  that,  in  the   Architect's   sole   discretion,   it  would  be
    inappropriate for the Architect to resolve the Claim.

    4.4.3 In evaluating  Claims,  the Architect  may, but shall not be obligated
    to, consult with or seek  information from either party or from persons with
    special  knowledge or expertise  who may assist the Architect in rendering a
    decision. The Architect may request the Owner to authorize retention of such
    persons at the Owner's expense.

    4.4.4 If the Architect  requests a party to provide a response to a Claim or
    to furnish additional supporting data, such party shall respond,  within ten
    days after receipt of such request,  and shall either  provide a response on
    the requested  supporting  data,  advise the Architect  when the response or
    supporting data will be furnished or advise the Architect that no supporting
    data will be furnished.  Upon receipt of the response or supporting data, if
    any, the  Architect  will either  reject or approve the Claim in whole or in
    part.

    4.4.5 The Architect will approve or reject Claims by written decision, which
    shall state the reasons  therefor  and which shall notify the parties of any
    change  in the  Contract  Sum or  Contract  Time or both.  The  approval  or
    rejection  of a Claim by the  Architect  shall be final and  binding  on the
    parties but subject to mediation and arbitration.



<PAGE>


    4.4.6 When a written  decision of the Architect states that (1) the decision
    is final but  subject  to  mediation  and  arbitration  and (2) a demand for
    arbitration  of a Claim covered by such decision must be made within 30 days
    after the date on which the  party  making  the  demand  receives  the final
    written decision,  then failure to demand  arbitration  within said 30 days'
    period shall result in the Architect's  decision  becoming final and binding
    upon the Owner and  Contractor.  If the Architect  renders a decision  after
    arbitration proceedings have been initiated, such decision may be entered as
    evidence,  but  shall  not  supersede  arbitration  proceedings  unless  the
    decision is acceptable to all parties concerned.

    4.4.7  Upon  receipt  of a  Claim  against  the  Contractor  or at any  time
    thereafter,  the Architect or the Owner may, but is not obligated to, notify
    the  surety,  if any,  of the nature  and amount of the Claim.  If the Claim
    relates to a possibility  of a  Contractor's  default,  the Architect or the
    Owner may,  but is not  obligated  to,  notify the  surety and  request  the
    surety's assistance in resolving the controversy.

4.4.8If a Claim  relates to or is the subject of a  mechanic's  lien,  the party
     asserting  such Claim may  proceed in  accordance  with  applicable  law to
     comply with the lien notice or filing  deadlines prior to resolution of the
     Claim by the Architect, by mediation or by arbitration.

4.4.9    MEDIATION
     4.5.1 Any Claim  arising  out of or  related  to the  Contract,  may,  upon
     agreement of the Contractor and Owner, be submitted to mediation.

     4.5.2 The parties  shall  endeavor  to resolve  their  Claims by  mediation
     which, unless the parties mutually agree otherwise,  shall be in accordance
     with the Construction  Industry Mediation Rules of the American Arbitration
     Association  currently in effect.  Request for mediation  shall be filed in
     writing  with the  other  party  to the  Contract  and  with  the  American
     Arbitration  Association.  The  request may be made  concurrently  with the
     filing of a demand for arbitration.

     4.5.3 The  parties  shall  share the  mediator's  fee and any  filing  fees
     equally.  The  mediation  shall be held in the place  where the  Project is
     located,  unless  another  location is  mutually  agreed  upon.  Agreements
     reached in mediation  shall be enforceable as settlement  agreements in any
     court having jurisdiction thereof.

     4.6 ARBITRATION
     4.6.1 Any Claim  arising out of or related to the  Contract,  except Claims
     relating to  aesthetic  effect and except  those  waived as provided for in
     Subparagraphs  4.3.10,  9.10.4 and  9.10.5,  shall,  after  decision by the
     Architect or 30 days after  submission  of the Claim to the  Architect,  be
     subject to arbitration.

     4.6.2  Claims not  resolved by  mediation  shall be decided by  arbitration
     which, unless the parties mutually agree otherwise,  shall be in accordance
     with  the  Construction   Industry   Arbitration   Rules  of  the  American
     Arbitration  Association  currently in effect.  The demand for  arbitration
     shall be filed in writing with the other party to the Contract and with the
     American  Arbitration  Association,  and a copy  shall  be  filed  with the
     Architect.

     4.6.3 A demand  for  arbitration  shall  be made  within  the  time  limits
     specified  in  Subparagraphs  4.4.6 and 4.6.1 as  applicable,  and in other
     cases within a reasonable time after the Claim has arisen,  and in no event
     shall it be made  after the date  when  institution  of legal or  equitable
     proceedings  based on such Claim would be barred by the applicable  statute
     of limitations as determined pursuant to Paragraph 13.7.

     4.6.4 Limitation on Consolidation or Joinder. Arbitration arising out of or
     relating to the Contract may include, by consolidation or joinder or in any
     other manner, the Architect,  the Architect's employees or consultants.  No
     arbitration  shall  include,  by  consolidation  or joinder or in any other
     manner,  parties other than the Owner,  Contractor,  Architect,  a separate
     contractor  as  described  in  Article  6 and other  persons  substantially
     involved in a common  question of fact or law whose presence is required if
     complete relief is to be accorded in arbitration. No person or entity other
     than the Owner, Contractors Architect or a separate contractor as described
     in Article 6 shall be included as an original



<PAGE>


     third party or additional  third party to an arbitration  whose interest or
     responsibility  is  insubstantial.  Consent  to  arbitration  involving  an
     additional person or entity shall not constitute  consent to arbitration of
     a Claim not  described  therein  or with a person  or  entity  not named or
     described  therein.   The  foregoing   agreement  to  arbitrate  and  other
     agreements to arbitrate with an additional  person or entity duly consented
     to by parties to the  Agreement  shall be  specifically  enforceable  under
     applicable law in any court having jurisdiction thereof.

     attorneys' fees and expenses incurred in arbitration and/or litigation.

ARTICLE 5 SUBCONTRACTORS
     5.1 DEFINITIONS
     5.1.1 A Subcontractor  is a person or entity who has a direct contract with
     the  Contractor  to  perform  a portion  of the Work at the site.  The term
     "Subcontractor"  is referred to  throughout  the  Contract  Documents as if
     singular   in  number   and  means  a   Subcontractor   or  an   authorized
     representative  of the  Subcontractor.  The term  "Subcontractor"  does not
     include a separate contractor or subcontractors of a separate contractor.

     5.1.2 A  Sub-subcontractor  is a  person  or  entity  who has a  direct  or
     indirect  contract with a Subcontractor to perform a portion of the Work at
     the site.  The term  "Sub-subcontractor"  is  referred  to  throughout  the
     Contract  Documents as if singular in number and means a  Sub-subcontractor
     or an authorized representative of the Sub-subcontractor.

     5.2 AWARD OF SUBCONTRACTS AND OTHER CONTRACTS FOR PORTIONS OF THE WORK
     5.2.1  Unless  otherwise  stated in the  Contract  Documents or the bidding
     requirements,  the  Contractor,  as soon as practicable  after award of the
     Contract,  shall  furnish in writing to the Owner through the Architect the
     names of persons or entities  (including those who are to furnish materials
     or equipment  fabricated to a special  design)  proposed for each principal
     portion of the Work. The Architect will promptly reply to the Contractor in
     writing  stating  whether  or not the  Owner or the  Architect,  after  due
     investigation,  has  reasonable  objection to any such  proposed  person or
     entity.  Failure  of  the  Owner  or  Architect  to  reply  promptly  shall
     constitute notice of no reasonable objection.

     5.2.2 The Contractor shall not contract with a proposed person or entity to
     whom the Owner or Architect has made reasonable and timely  objection.  The
     Contractor  shall  not be  required  to  contract  with  anyone to whom the
     Contractor has made reasonable objection.

     5.2.3 If the Owner or  Architect  has  reasonable  objection to a person or
     entity proposed by the Contractor,  the Contractor shall propose another to
     whom the Owner or Architect  has no reasonable  objection.  If the proposed
     but rejected  Subcontractor was reasonably  capable of performing the Work,
     the Contract  Sum and Contract  Time shall be increased or decreased by the
     difference,  if any,  occasioned by such change,  and an appropriate Change
     Order shall be issued before commencement of the substitute Subcontractor's
     Work.

     5.2.4 The  Contractor  shall not change a  Subcontractor,  person or entity
     previously selected if the Owner or Architect makes reasonable objection to
     such substitute.

     5.3 SUBCONTRACTUAL RELATIONS
     5.3.1  By  appropriate  agreement,   written  where  legally  required  for
     validity, the Contractor shall require each Subcontractor, to the extent of
     the  Work  to be  performed  by  the  Subcontractor,  to be  bound  to  the
     Contractor  by terms of the Contract  Documents,  and to assume  toward the
     Contractor  all  the  obligations  and   responsibilities,   including  the
     responsibility   for  safety  of  the   Subcontractor's   Work,  which  the
     Contractor,  by these  Documents,  assumes  toward the Owner and Architect.
     Each  subcontract  agreement  shall  preserve and protect the rights of the
     Owner and Architect  under the Contract  Documents with respect to the Work
     to be performed by the  Subcontractor so that  subcontracting  thereof will
     not prejudice  such rights,  and shall allow to the  Subcontractor,  unless
     specifically provided otherwise in the subcontract  agreement,  the benefit
     of all  rights,  remedies  and  redress  against  the  Contractor  that the
     Contractor, by the Contract Documents, has against the Owner. Where

     appropriate,  the Contractor shall require each Subcontractor to enter into
     similar  agreements  with  Sub-subcontractors.  The  Contractor  shall make
     available to each  proposed  Subcontractor,  prior to the  execution of the
     subcontract  agreement,  copies  of the  Contract  Documents  to which  the
     Subcontractor   will  be  bound,   and,   upon   written   request  of  the
     Subcontractor,  identify to the  Subcontractor  terms and conditions of the
     proposed  subcontract  agreement which may be at variance with the Contract
     Documents. Subcontractors will similarly make copies of applicable portions
     of   such    documents    available    to   their    respective    proposed
     Sub-subcontractors.

     5.4 CONTINGENT ASSIGNMENT OF SUBCONTRACTS


ARTICLE 6 CONSTRUCTION BY OWNER OR BY SEPARATE CONTRACTORS
     6.1 OWNER'S RIGHT TO PERFORM CONSTRUCTION AND TO AWARD SEPARATE CONTRACTS
     6.1.1 The Owner  reserves the right to perform  construction  or operations
     related to the Project with the Owner's own forces,  and to award  separate
     contracts  in  connection  with  other  portions  of the  Project  or other
     construction  or  operations  on the site under  Conditions of the Contract
     identical  or  substantially  similar  to these  including  those  portions
     related to insurance and waiver of  subrogation.  If the Contractor  claims
     that delay or  additional  cost is  involved  because of such action by the
     Owner, the Contractor shall make such Claim as provided in Paragraph 4.3.

     6.1.2 When separate  contracts  are awarded for  different  portions of the
     Project  or  other  construction  or  operations  on  the  site,  the  term
     "Contractor"  in the  Contract  Documents  in  each  case  shall  mean  the
     Contractor who executes each separate Owner-Contractor Agreement.

     6.1.3 The Owner shall  provide for  coordination  of the  activities of the
     Owner's  own forces and of each  separate  contractor  with the Work of the
     Contractor, who shall cooperate with them. The Contractor shall participate
     with  other  separate   contractors   and  the  Owner  in  reviewing  their
     construction  schedules when directed to do so. The  Contractor  shall make
     any revisions to the  construction  schedule deemed necessary after a joint
     review  and  mutual  agreement.   The  construction  schedules  shall  then
     constitute the schedules to be used by the Contractor, separate contractors
     and the Other until  subsequently  revised.  The  Contract Sum and Contract
     Time  shall  be  equitably  adjusted  for  any  charges  arising  from  the
     activities provided for in Paragraphs 6.1 and 6.2.

     6.1.4 Unless otherwise provided in the Contract  Documents,  when the Owner
     performs construction or operations related to the Project with the Owner's
     own forces, the Owner shall be deemed to be subject to the same obligations
     and to have  the  same  rights  which  apply to the  Contractor  under  the
     Conditions of the Contract,  including,  without  excluding  others,  those
     stated in Article 3, this Article 6 and Articles 10, II and 12.

     6.2 MUTUAL RESPONSIBILITY
     6.2.1 The  Contractor  shall  afford  the Owner  and  separate  contractors
     reasonable  opportunity for introduction and storage of their materials and
     equipment  and  performance  of their  activities,  and shall  connect  and
     coordinate the  Contractor's  construction  and  operations  with theirs as
     required by the Contract Documents.

     6.2.2 If part of the  Contractor's  Work  depends for proper  execution  or
     results  upon  construction  or  operations  by  the  Owner  or a  separate
     contractor,  the Contractor shall, prior to proceeding with that portion of
     the  Work,  promptly  report to the  Architect  apparent  discrepancies  or
     defects in such other construction that would render it unsuitable for such
     proper execution and results.  Failure of the Contractor so to report shall
     constitute  an  acknowledgment  that the Owner s or  separate  contractor's
     completed or partially completed  construction is fit and proper to receive
     the   Contractor's   Work,   except  as  to  defects  not  then  reasonably
     discoverable.



<PAGE>


     6.2.3 The Owner shall be reimbursed by the Contractor for costs incurred by
     the Owner  which are  payable to a separate  contractor  because of delays,
     improperly  timed  activities or defective  construction of the Contractor.
     The Owner shall be  responsible to the Contractor for costs incurred by the
     Contractor  because of delays,  improperly timed activities,  damage to the
     Work or defective construction of a separate contractor.

     6.2.4 The Contractor shall promptly remedy damage  wrongfully caused by the
     Contractor to completed or partially completed  construction or to property
     of the Owner or separate contractors as provided in Subparagraph 10.2.5.

     6.2.5  The  Owner  and  each  separate   contractor  shall  have  the  same
     responsibilities  for  cutting  and  patching  as  are  described  for  the
     Contractor in Subparagraph 3.14.

     6.3 OWNER'S RIGHT TO CLEAN UP
     6.3.1 If a dispute arises among the  Contractor,  separate  contractors and
     the Owner as to the  responsibility  under their  respective  contracts for
     maintaining the premises and surrounding area free from waste materials and
     rubbish,  the Owner may clean up and the  Architect  will allocate the cost
     among those responsible.


ARTICLE 7 CHANGES IN THE WORK
     7.1 GENERAL
     7.1.1  Changes  in the  Work may be  accomplished  after  execution  of the
     Contract,   and  without  invalidating  the  Contract,   by  Change  Order,
     Construction  Change  Directive  or order  for a minor  change in the Work,
     subject to the  limitations  stated in this Article 7 and  elsewhere in the
     Contract Documents.

     7.1.2 A Change  Order  shall be  based  upon  agreement  among  the  Owner,
     Contractor  and  Architect;   a  Construction   Change  Directive  requires
     agreement by the Owner and Architect and may or may not be agreed to by the
     Contractor;  an order  for a minor  change in the Work may be issued by the
     Architect alone.

     7.1.3 Changes in the Work shall be performed under applicable provisions of
     the Contract Documents,  and the Contractor shall proceed promptly,  unless
     otherwise  provided in the Change Order,  Construction  Change Directive or
     order for a minor change in the Work.

     7.2  CHANGE ORDERS
     7.2.1 A Change Order is a written instrument  prepared by the Architect and
     signed by the Owner, Contractor and Architect, stating their agreement upon
     all of the following:

              .1  change in the Work;

              .2  the amount of the adjustment, if any, in the Contract Sum; and

              .3  the extent of the adjustment, if any, in the Contract Time.

     7.2.2  Methods  used in  determining  adjustments  to the  Contract Sum may
include those listed in Subparagraph 7.3.3.

     7.3  CONSTRUCTION CHANGE DIRECTIVES
     7.3.1 A  Construction  Change  Directive is a written order prepared by the
     Architect and signed by the Owner and Architect,  directing a change in the
     Work prior to  agreement  on  adjustment,  if any, in the  Contract  Sum or
     Contract Time, or both.  The Owner may by  Construction  Change  Directive,
     without  invalidating  the  Contract,  order changes in the Work within the
     general scope of the Contract  consisting of additions,  deletions or other
     revisions, the Contract Sum and Contract Time being adjusted accordingly.

     7.3.2 A Construction Change Directive shall be used in the absence of total
agreement on the terms of a Change Order.

     7.3.3 If the Construction  Change  Directive  provides for an adjustment to
     the Contract  Sum, the  adjustment  shall be based on one of the  following
     methods:

              .1  mutual  acceptance  of a lump sum  properly  itemized  and 
                  supported  by  sufficient  substantiating  data to permit
                  evaluation;

              .2  unit prices stated in the Contract Documents or subsequently 
                  agreed upon;

              .3  cost to be determined in a manner agreed upon by the parties
                  and a mutually acceptable fixed or percentage fee; or

              .4  as provided in Subparagraph 7.3.6.

     7.3.4 Upon receipt of a Construction Change Directive, the Contractor shall
     promptly  proceed  with the  change in the Work  involved  and  advise  the
     Architect of the Contractor's agreement or disagreement with the method, if
     any,  provided in the  Construction  Change  Directive for  determining the
     proposed adjustment in the Contract Sum or Contract Time.

     7.3.5 A Construction  Change Directive  signed by the Contractor  indicates
     the agreement of the Contractor therewith, including adjustment in Contract
     Sum and Contract Time or the method for  determining  them.  Such agreement
     shall be effective immediately and shall be recorded as a Change Order.

     7.3.6 If the  Contractor  does not respond  promptly or disagrees  with the
     method for  adjustment in the Contract  Sum, the method and the  adjustment
     shall be determined on the basis of reasonable  expenditures and savings of
     those performing the Work attributable to the change, including, in case of
     an increase in the Contract  Sum, a reasonable  allowance  for overhead and
     profit.  In such case, and also under Clause 7.3.3.3,  the Contractor shall
     keep and present, in such form as the Architect may prescribe,  an itemized
     accounting  together with  appropriate  supporting  data.  Unless otherwise
     provided  in the  Contract  Documents,  costs  for  the  purposes  of  this
     Subparagraph 7.3.6 shall be limited to the following:

              .1  costs  of  labor,  including  social  security,  old  age  and
                  unemployment insurance,  fringe benefits required by agreement
                  or custom, and workers' compensation insurance;

              .2  costs of materials, supplies and equipment, including cost of
                  transportation, whether incorporated or consumed;

              .3  rental costs of machinery and equipment, exclusive of hand
                  tools, whether rented from the Contractor or others;

              .4  costs of premiums for all bonds and insurance, permit fees,
                  and sales, use or similar taxes related to the Work; and

              .5  additional  costs of  supervision  field office  personnel and
                  field office costs directly attributable to the change.


     7.3.7 The amount of credit to be allowed by the Contractor to the Owner for
     a deletion or change  which  results in a net  decrease in the Contract Sum
     shall be actual net cost. When both additions and credits  covering related
     Work or substitutions are involved in a change,  the allowance for overhead
     and  profit  shall be figured on the basis of net  increase,  if any,  with
     respect to that change.

     7.3.8  Pending  final  determination  of the total  cost of a  Construction
     Change  Directive to the Owner,  amounts not in dispute for such changes in
     the Work shall be included in  Applications  for Payment  accompanied  by a
     Change Order  indicating  the parties'  agreement  with part or all of such
     costs. For any portion of such cost that remains in dispute,  the Architect
     will make an interim  determination  for purposes of monthly  certification
     for payment for those costs.  That  determination  of cost shall adjust the
     Contract Sum on the same basis as a Change  Order,  subject to the right of
     either party to disagree and assert a claim in accordance with Article 4.

     7.3.9 When the Owner and Contractor  agree with the  determination  made by
     the Architect  concerning the  adjustments in the Contract Sum and Contract
     Time, or otherwise  reach  agreement upon the  adjustments,  such agreement
     shall be effective  immediately  and shall be recorded by  preparation  and
     execution of an appropriate Change Order.




<PAGE>


     7.4 MINOR CHANGES IN THE WORK
     7.4.1 The Architect  will have authority to order minor changes in the Work
     not  involving  adjustment in the Contract Sum or extension of the Contract
     Time and not inconsistent with the intent of the Contract  Documents.  Such
     changes  shall be  effected  by  written  order and shall be binding on the
     Owner and  Contractor.  The Contractor  shall carry out such written orders
     promptly.


ARTICLE 8 TIME
     8.1 DEFINITIONS
     8.1.1  Unless  otherwise  provided,  Contract  Time is the  period of time,
     including  authorized  adjustments,  allotted in the Contract Documents for
     Substantial Completion of the Work.

     8.1.2 The date of commencement  of the Work is the date  established in the
     Agreement.

     8.1.3 The date of  Substantial  Completion  is the date upon which the Work
     has achieved the standards set forth in sub-paragraph 9.8.1.

     8.1.4 The term "day" as used in the Contract  Documents shall mean calendar
     day unless otherwise specifically defined.

     8.2 PROGRESS AND COMPLETION
     8.2.1 Time limits  stated in the Contract  Documents  are of the essence of
     the Contract.  By executing the Agreement the Contractor  confirms that the
     Contract Time is a reasonable period for performing the Work.

     8.2.2  The  Contractor   shall  not  knowingly,   except  by  agreement  or
     instruction of the Owner in writing, prematurely commence operations on the
     site or elsewhere  prior to the  effective  date of  insurance  required by
     Article  11 to be  furnished  by the  Contractor  and  Owner.  The  date of
     commencement of the Work shall not be changed by the effective date of such
     insurance.  Unless the date of  commencement is established by the Contract
     Documents or a notice to proceed given by the Owner,  the Contractor  shall
     notify the Owner in writing not less than five days or other agreed  period
     before  commencing  the Work to permit  the  timely  filing  of  mortgages,
     mechanic's liens and other security interests.

     8.2.3 The Contractor shall proceed  expeditiously  with adequate forces and
     shall achieve Substantial Completion within the Contract Time.

     8.3 DELAYS AND EXTENSIONS OF TIME
     8.3.1 If the  Contractor  is  delayed  at any time in the  commencement  or
     progress of the Work by an act or neglect of the Owner or Architect,  or of
     an employee of either, or of a separate  contractor  employed by the Owner,
     or by changes  ordered in the Work,  or by labor  disputes,  fire,  unusual
     delay in  deliveries,  unavoidable  casualties  or other causes  beyond the
     Contractor's control, or by delay authorized by the Owner pending mediation
     and  arbitration,  or by other causes which the  Architect  determines  may
     justify delay, then the Contract Time shall be extended by Change Order for
     such time as completion of the Work has been delayed.

     8.3.2 Claims  relating to time shall be made in accordance  with applicable
     provisions of Paragraph 4.3.

     8.3.3    This  Paragraph  8.3 does not  preclude  recovery of damages for 
     delay by either  party  under  other  provisions  of the
     Contract Documents.


ARTICLE 9 PAYMENTS AND COMPLETION
     9.1 CONTRACT SUM
     9.1.1 The Contract Sum is stated in the Agreement and, including authorized
     adjustments or other amounts to which the Contractor may become entitled in
     accordance with the terms hereof,  is the total amount payable by the Owner
     to the Contractor for performance of the Work under the Contract Documents.

     9.2 SCHEDULE OF VALUES
     9.2.1 Before the first Application for Payment, the Contractor shall submit
     to the Architect a schedule of values  allocated to various portions of the
     Work,  prepared in such form and supported by such data to substantiate its
     accuracy as the Architect may



<PAGE>


     reasonably  require.  This schedule,  unless  objected to by the Architect,
     shall be used as a basis for reviewing the  Contractor's  Applications  for
     Payment.

     9.3 APPLICATIONS FOR PAYMENT
     9.3.1 At least  ten days  before  the date  established  for each  progress
     payment,   the  Contractor  shall  submit  to  the  Architect  an  itemized
     Application  for Payment for  operations  completed in accordance  with the
     schedule of values. Such application shall be notarized,  if required,  and
     supported by such data  substantiating the Contractor's right to payment as
     the  Owner  or  Architect  may  reasonably  require,   such  as  copies  of
     requisitions from  Subcontractors  and material  suppliers,  and reflecting
     retainage if provided for in the Contract Documents.

     9.3.1.1 As provided in Subparagraph  7.3.8,  such  applications may include
     requests  for  payment  on  account  of changes in the Work which have been
     properly  authorized  by  Construction  Change  Directives,  or by  interim
     determinations of the Architect, but not yet included in Change Orders.

     9.3.1.2 Such applications may not include requests for payment for portions
     of  the  Work  for  which  the  Contractor  does  not  intend  to  pay to a
     Subcontractor or material supplier,  unless such Work has been performed by
     others  whom the  Contractor  intends to pay or has been  performed  by the
     Contractor.

     9.3.2 Unless otherwise provided in the Contract  Documents,  payments shall
     be made on account of materials and equipment delivered and suitably stored
     at the site for  subsequent  incorporation  in the  Work.  If  approved  in
     advance by the Owner,  payment  may  similarly  be made for  materials  and
     equipment  suitably  stored  off the  site  at a  location  agreed  upon in
     writing.  Payment for  materials  and  equipment  stored on or off the site
     shall be  conditioned  upon  compliance by the Contractor  with  procedures
     satisfactory  to the Owner to establish the Owner's title to such materials
     and equipment or otherwise protect the Owner's interest,  and shall include
     the costs of applicable  insurance,  storage and transportation to the site
     for such materials and equipment stored off the site.

     9.3.3  The  Contractor  warrants  that  title  to all  Work  covered  by an
     Application  for  Payment  will pass to the Owner no later than the time of
     payment.  The  Contractor  further  warrants  that  upon  submittal  of  an
     Application  for Payment all Work for which  Certificates  for Payment have
     been previously  issued and payments  received from the Owner shall, to the
     best of the Contractor's  knowledge,  information and belief, except as the
     Contractor  may  advise  the  Owner be free and  clear  of  liens,  claims,
     security   interests   or   encumbrances   in  favor  of  the   Contractor,
     Subcontractors,  material suppliers,  or other persons or entities making a
     claim by reason of having provided labor,  materials and equipment relating
     to the Work.

     9.4 CERTIFICATES FOR PAYMENT
     9.4.1  The  Architect  will,   within  seven  days  after  receipt  of  the
     Contractor's   Application  for  Payment,  either  issue  to  the  Owner  a
     Certificate for Payment, with a copy to the Contractor,  for such amount as
     the  Architect  determines is properly  due, or notify the  Contractor  and
     Owner in writing of the Architect's  reasons for withholding  certification
     in whole or in part as provided in Subparagraph 9.5.1.

     9.4.2  The  issuance  of  a  Certificate  for  Payment  will  constitute  a
     representation  by the  Architect  to the Owner,  based on the  Architect's
     evaluation of the Work and the data comprising the Application for Payment,
     that the Work has  progressed to the point  indicated and that, to the best
     of the Architect's  knowledge,  information and belief,  the quality of the
     Work  is  in  accordance  with  the  Contract   Documents.   The  foregoing
     representations  are subject to an evaluation  of the Work for  conformance
     with the Contract  Documents  upon  Substantial  Completion,  to results of
     subsequent  tests and  inspections,  to correction of minor deviations from
     the Contract  Documents prior to completion and to specific  qualifications
     expressed by the Architect.  The issuance of a Certificate for Payment will
     further  constitute a  representation  that the  Contractor  is entitled to
     payment in the amount certified. However, the issuance of a Certificate for
     Payment  will  not be a  representation  that  the  Architect  has (1) made
     exhaustive  or  continuous  on-site  inspections  to check the  quality  or
     quantity of the Work, (2) reviewed construction means, methods, techniques,
     sequences or procedures,  (3) reviewed copies of requisitions received from
     Subcontractors and material suppliers and other data requested by the Owner
     to substantiate the Contractor's right to payment,  or (4) made examination
     to  ascertain  how or for  what  purpose  the  Contractor  has  used  money
     previously paid on account of the Contract Sum.

     9.5 DECISIONS TO WITHHOLD CERTIFICATION
     9.5.1 The Architect  may withhold a Certificate  for Payment in whole or in
     part,  to the extent  reasonably  necessary  to protect  the Owner,  if the
     representations to the Owner required by Subparagraph 9.4.2 cannot be made.
     If the  Architect  is  unable  to  certify  payment  in the  amount  of the
     Application, the Architect will notify the Contractor and Owner as



<PAGE>


     provided in  Subparagraph  9.4.1.  If the Contractor  and Architect  cannot
     agree on a revised amount,  the Architect will promptly issue a Certificate
     for  Payment  for the amount for which the  Architect  is able to make such
     representations to the Owner. The Architect may also withhold a Certificate
     for Payment or, because of subsequently  discovered  evidence,  may nullify
     the whole or a part of a Certificate for Payment previously issued, to such
     extent as may be necessary in the Architect's  opinion to protect the Owner
     from loss for which the Contractor is responsible, including loss resulting
     from acts and omissions described in Subparagraph 3.3.2, because of:

              .1  defective Work not remedied;

              .2  third party claims  filed or  reasonable  evidence  indicating
                  probable filing of such claims unless  security  acceptable to
                  the Owner is provided by the Contractor;

              .3  failure of the Contractor to make payments properly to 
                  Subcontractors or for labor, materials or equipment;

              .4  reasonable evidence that the Work cannot be completed for the
                  unpaid balance of the Contract Sum;

              .5  damage to the Owner or another contractor;

              .6  reasonable evidence that the Work will not be completed within
                  the Contract  Time,  and that the unpaid  balance would not be
                  adequate  to  cover  actual  or  liquidated  damages  for  the
                  anticipated delay; or
              .7  persistent failure to carry out the Work in accordance with 
                  the Contract Documents.

     9.5.2 When the above  reasons for  withholding  certification  are removed,
     certification will be made for amounts previously withheld.

     9.6 PROGRESS PAYMENTS
     9.6.1 After the Architect has issued a Certificate  for Payment,  the Owner
     shall make  payment in the  manner  and  within  the time  provided  in the
     Contract Documents, and shall so notify the Architect.

     9.6.2 The Contractor shall promptly pay each Subcontractor, upon receipt of
     payment from the Owner, out of the amount paid to the Contractor on account
     of such  Subcontractor's  portion  of the Work,  the  amount to which  said
     Subcontractor is entitled,  reflecting  percentages  actually retained from
     payments to the  Contractor on account of such  Subcontractor's  portion of
     the  Work.  The  Contractor  shall,  by  appropriate  agreement  with  each
     Subcontractor,   require   each   Subcontractor   to   make   payments   to
     Sub-subcontractors in a similar manner.

     9.6.3 The  Architect  will,  on  request,  furnish to a  Subcontractor,  if
     practicable,  information  regarding  percentages  of completion or amounts
     applied for by the Contractor and action taken thereon by the Architect and
     Owner on account of portions of the Work done by such Subcontractor.

     9.6.4 Neither the Owner nor Architect shall have an obligation to pay or to
     see to the payment of money to a  Subcontractor  except as may otherwise be
     required by law.

     9.6.5 Payment to material suppliers shall be treated in a manner similar to
     that provided in Subparagraphs 9.6.2, 9.6.3 and 9.6.4.

     9.6.6 A Certificate for Payment,  a progress payment,  or partial or entire
     use or  occupancy  of  the  Project  by  the  Owner  shall  not  constitute
     acceptance of Work not in accordance with the Contract Documents.

     9.6.7 Unless the  Contractor  provides the Owner with a payment bond in the
     full penal sum of the Contract Sum, payments received by the Contractor for
     Work properly  performed by  Subcontractors  and suppliers shall be held by
     the Contractor for those  Subcontractors or suppliers who performed Work or
     furnished materials,  or both, under contract with the Contractor for which
     payment was made by the Owner. Nothing contained herein shall require money
     to be placed in a separate  account  and not  commingled  with money of the
     Contractor,  shall create any fiduciary  liability or tort liability on the
     part of the  Contractor  for breach of trust or shall entitle any person or
     entity to an award of punitive damages against the Contractor for breach of
     the requirements of this provision.

     9.7 FAILURE OF PAYMENT
     9.7.1 If the Architect does not issue a Certificate for Payment, through no
     fault  of  the   Contractor,   within  seven  days  after  receipt  of  the
     Contractor's  Application  for  Payment,  or if the Owner  does not pay the
     Contractor  within  seven days after the date  established  in the Contract
     Documents the amount  certified by the Architect or awarded by arbitration,
     then the Contractor may, upon three  additional days' written notice to the
     Owner and  Architect,  stop the Work until  payment of the amount owing has
     been received.  The Contract Time shall be extended  appropriately  and the
     Contract  Sum  shall  be  increased  by  the  amount  of  the  Contractor's
     reasonable  costs of  shut-down,  delay  and  start-up,  plus  interest  as
     provided for in the Contract Documents.

     9.8 SUBSTANTIAL COMPLETION
     9.8.1 Substantial  Completion is the stage in the progress of the Work when
     the  Work  or  designated  portion  thereof  is  sufficiently  complete  in
     accordance  with the  Contract  Documents  so that the Owner can  occupy or
     utilize the Work for its intended use.

     9.8.2 When the  Contractor  considers  that the Work, or a portion  thereof
     which the Owner agrees to accept separately, is substantially complete, the
     Contractor shall notify the Architect.  who shall prepare and submit to the
     Architect a comprehensive  list of items to be completed or corrected prior
     to final  payment.  Failure  to include an item on such list does not alter
     the  responsibility  of the  Contractor  to complete all Work in accordance
     with the Contract Documents.

     9.8.3 The Architect  will make an inspection to determine  whether the Work
     or designated portion thereof is substantially complete. If the Architect's
     inspection  discloses any item, whether or not included on the Contractor's
     list,  which is not  sufficiently  complete in accordance with the Contract
     Documents  so that the Owner can occupy or utilize  the Work or  designated
     portion thereof for its intended use, the Contractor shall, before issuance
     of the Certificate of Substantial Completion, complete or correct such item
     upon notification by the Architect. In such case, the Contractor shall then
     submit a request for  another  inspection  by the  Architect  to  determine
     Substantial Completion.

     9.8.4  When  the  Work  or  designated  portion  thereof  is  substantially
     complete,   the  Architect   will  prepare  a  Certificate  of  Substantial
     Completion which shall establish the date of Substantial Completion,  shall
     establish  responsibilities  of the  Owner  and  Contractor  for  security,
     maintenance,  heat, utilities,  damage to the Work and insurance, and shall
     fix the time within which the Contractor shall finish all items on the list
     accompanying the Certificate. Warranties required by the Contract Documents
     shall  commence  on the  date  of  Substantial  Completion  of the  Work or
     designated  portion thereof unless otherwise provided in the Certificate of
     Substantial Completion.

     9.8.5 The Certificate of Substantial  Completion  shall be submitted to the
     Owner and  Contractor  for their  written  acceptance  of  responsibilities
     assigned to them in such  Certificate.  Upon such acceptance and consent of
     surety, if any, the Owner shall make payment of retainage  applying to such
     Work or designated portion thereof. Such payment shall be adjusted for Work
     that is  incomplete  or not in  accordance  with  the  requirements  of the
     Contract Documents.

     9.9 PARTIAL OCCUPANCY OR USE
     9.9.1 The Owner may  occupy or use any  completed  or  partially  completed
     portion  of the Work at any  stage  when  such  portion  is  designated  by
     separate  agreement with the Contractor,  provided such occupancy or use is
     consented  to  by  the  insurer  as  required  under  Clause  11.4.1.5  and
     authorized by public  authorities  having  jurisdiction over the Work. Such
     partial  occupancy  or use  may  commence  whether  or not the  portion  is
     substantially complete,  provided the Owner and Contractor have accepted in
     writing  the  responsibilities  assigned  to  each of  them  for  payments,
     retainage, if any, security,  maintenance,  heat, utilities,  damage to the
     Work and  insurance,  and have agreed in writing  concerning the period for
     correction  of the Work and  commencement  of  warranties  required  by the
     Contract Documents.  When the Contractor considers a portion  substantially
     complete,  the Contractor  shall notify the Architect who shall prepare and
     submit  a list to the  Architect  as  provided  under  Subparagraph  9.8.2.
     Consent  of  the  Contractor  to  partial  occupancy  or use  shall  not be
     unreasonably  withheld.  The  stage of the  progress  of the Work  shall be
     determined by written  agreement between the Owner and Contractor or, if no
     agreement is reached, by decision of the Architect.


     9.9.2  Immediately  prior to such  partial  occupancy  or use,  the  Owner,
     Contractor and Architect  shall jointly  inspect the area to be occupied or
     portion  of the  Work to be used in  order  to  determine  and  record  the
     condition of the Work.

     9.9.3 Unless otherwise agreed upon,  partial  occupancy or use of a portion
     or  portions  of the  Work  shall  not  constitute  acceptance  of Work not
     complying with the requirements of the Contract Documents.

     9.10     FINAL COMPLETION AND FINAL PAYMENT
     9.10.1  Upon  receipt  of written  notice  that the Work is ready for final
     inspection  and  acceptance  and upon  receipt of a final  Application  for
     Payment,  the Architect will promptly make such inspection and, if the Work
     is  acceptable  under  the  Contract   Documents  and  the  Contract  fully
     performed,  the  Architect  will  promptly  issue a final  Certificate  for
     Payment stating that to the best of the Architect's knowledge,  information
     and  belief,  and on  the  basis  of the  Architect's  on-site  visits  and
     inspections,  the Work has been  completed  in  accordance  with  terms and
     conditions of the Contract  Documents and that the entire  balance found to
     be due  the  Contractor  and  noted  in the  final  Certificate  is due and
     payable.  The Architect's  final  Certificate for Payment will constitute a
     further  representation  that conditions  listed in Subparagraph  9.10.2 as
     precedent to the  Contractor's  being  entitled to final  payment have been
     fulfilled.

     9.10.2 Neither final payment nor any remaining  retained  percentage  shall
     become due until the  Contractor  submits to the Architect (1) an affidavit
     that payrolls,  bills for materials and equipment,  and other  indebtedness
     connected  with the Work for which the Owner or the Owner's  property might
     be  responsible  or encumbered  (less amounts  withheld by Owner) have been
     paid or otherwise  satisfied,  (2) a certificate  evidencing that insurance
     required by the Contract  Documents to remain in force after final  payment
     is  currently in effect and will not be canceled or allowed to expire until
     at least 30 days' prior written  notice has been given to the Owner,  (3) a
     written  statement that the Contractor knows of no substantial  reason that
     the  insurance  will not be renewable  to cover the period  required by the
     Contract  Documents,  (4) consent of surety,  if any, to final  payment and
     (5),  if  required  by  the  Owner,  other  data  establishing  payment  or
     satisfaction  of  obligations,  such as  receipts,  releases and waivers of
     liens,  claims,  security  interests  or  encumbrances  arising  out of the
     Contract, to the extent and in such form as may be designated by the Owner.
     If a  Subcontractor  refuses to furnish a release or waiver required by the
     Owner,  the  Contractor  may  furnish a bond  satisfactory  to the Owner to
     indemnify  the Owner  against such lien.  If such lien remains  unsatisfied
     after payments are made, the Contractor shall refund to the Owner all money
     that the Owner may be compelled to pay in discharging such lien,  including
     all costs and reasonable attorneys' fees.

     9.10.3 If,  after  Substantial  Completion  of the Work,  final  completion
     thereof is  materially  delayed  through no fault of the  Contractor  or by
     issuance    of    Change     Orders     affecting     final     completion,
     and-the-Afehiteet-se-ees4ifess  the Owner shall,  upon  application  by the
     Contractor and certification by the Architect,  and without terminating the
     Contract,  make  payment of the  balance  due for that  portion of the Work
     fully completed and accepted.  If the remaining  balance for Work not fully
     completed or corrected is less than  retainage  stipulated  in the Contract
     Documents,  and if bonds have been furnished, the written consent of surety
     to payment of the balance due for that portion of the Work fully  completed
     and accepted shall be submitted by the Contractor to the Architect prior to
     certification  of such payment.  Such payment shall be made under terms and
     conditions  governing final payment,  except that it shall not constitute a
     waiver of claims.  9.10.4 The making of final  payment  shall  constitute a
     waiver of Claims by the Owner except those arising from:
             .1 liens, Claims, security interests or encumbrances arising out of
             the Contract and  unsettled;  .2 failure of the Work to comply with
             the requirements of the Contract Documents;  or .3 terms of special
             warranties required by the Contract Documents.

     9.10.5  Acceptance of final payment by the Contractor,  a Subcontractor  or
     material  supplier shall not constitute a waiver of claims  previously made
     in writing  except as  identified by that payee as settled or waived at the
     time of final Application for Payment.


ARTICLE 10 PROTECTION OF PERSONS AND PROPERTY
     10.1     SAFETY PRECAUTIONS AND PROGRAMS

                  replacement in the course of construction.

     10.2.2 The Contractor  shall give notices and comply with applicable  laws,
     ordinances,  rules,  regulations  and lawful  orders of public  authorities

     supervision of properly qualified personnel.

     damage or loss insured under  property  insurance  required by the Contract
     Documents) to property  referred to in Clauses 10.2.1.2 and 10.2.1.3 caused
     in   whole   or  in   part   by  the   Contractor,   a   Subcontractor,   a
     Sub-subcontractor,  or anyone  directly  or  indirectly  employed by any of
     them,  or by anyone  for  whose.  acts they may be liable and for which the
     Contractor  is  responsible  under Clauses  10.2.1.2 and  10.2.1.3,  except
     damage or loss  attributable to acts or omissions of the Owner or Architect
     or anyone  directly or indirectly  employed by either of them, or by anyone
     for whose acts either of them may be liable,  and not  attributable  to the
     fault or negligence of the  Contractor.  The foregoing  obligations  of the
     Contractor are in addition to the Contractor's  obligations under Paragraph
     3.18.

     10.2.6  The  Contractor  shall  designate  a  responsible   member  of  the
     Contractor's organization at the site whose duty shall be the prevention of
     accidents.  This person  shall be the  Contractor's  superintendent  unless
     otherwise  designated  by  the  Contractor  in  writing  to the  Owner  and
     Architect.

     10.2.7 The Contractor shall not load or permit any part of the construction
or site to be loaded so as to endanger its safety.


     10.3     HAZARDOUS MATERIALS

     bodily injury or death to persons  resulting  from a material or substance,
     including but not limited to asbestos or  polychlorinated  biphenyl  (PCB),
     encountered  on the site by the  Contractor,  the  Contractor  shall,  upon
     recognizing the condition,  immediately  stop Work in the affected area and
     report the condition to the Owner and Architect in writing.

     10.3.2 The Owner  shall  obtain the  services of a licensed  laboratory  to
     verify the presence or absence of the material or substance reported by the
     Contractor  and,  in the event such  material or  substance  is found to be
     present,  to verify that it has been rendered  harmless.  Unless  otherwise
     required by the Contract  Documents,  the Owner shall furnish in writing to
     the  Contractor  and Architect the names and  qualifications  of persons or
     entities who are to perform tests verifying the presence or absence of such

     containment of such material or substance. The Contractor and the Architect
     will promptly reply to the Owner in writing  stating  whether or not either
     has reasonable  objection to the persons or entities proposed by the Owner.
     If either the  Contractor  or  Architect  has an  objection  to a person or
     entity  proposed by the Owner,  the Owner shall propose another to whom the
     Contractor  and  the  Architect  have no  reasonable  objection.  When  the

<PAGE>


     area if in fact the  material  or  substance  presents  the risk of  bodily
     injury  or death  as  described  in  Subparagraph  10.3.1  and has not been
     rendered  harmless,  provided that such claim,  damage,  loss or expense is
     attributable to bodily injury, sickness,  disease or death, or to injury to
     or  destruction  of  tangible  property  (other  than the Work  itself) and
     provided  that  such  damage,  loss  or  expense  is not  due  to the  sole
     negligence of a party seeking indemnity.

     and substances  brought to the site by the Contractor unless such materials
     or substances were required by the Contract Documents.

     payment and are reasonably available,  an additional certificate evidencing
     continuation of such coverage shall be submitted with the final Application

     for the entire  Project  at the site on a  replacement  cost basis  without
     optional deductibles.  Such property insurance shall be maintained,  unless
     otherwise provided in the Contract Documents or otherwise agreed in writing
     by all persons and entities who are beneficiaries of such insurance,  until
     final  payment  has been made as  provided  in  Paragraph  9.10 or until no
     person or entity  other  than the Owner has an  insurable  interest  in the
     property required by this Paragraph 11.4 to be covered, whichever is later.
     This  insurance  shall  include  interests  of the Owner,  the  Contractor,
     Subcontractors and Sub-subcontractors in the Project.

     11.4.1.1 Property  insurance shall be on an "all-risk" or equivalent policy
     form and shall include, without limitation, insurance against the perils of
     fire  (with  extended  coverage)  and  physical  loss or damage  including,
     without  duplication of coverage,  theft,  vandalism,  malicious  mischief,
     collapse,  earthquake,  flood, windstorm,  falsework,  testing and startup,
     temporary buildings and debris removal including  demolition  occasioned by
     enforcement  of  any  applicable  legal   requirements,   and  shall  cover
     reasonable  compensation  for  Architect's  and  Contractor's  services and
     expenses required as a result of such insured loss.

     11.4.1.2 If the Owner does not intend to purchase such  property  insurance
     required  by the  Contract  and with  all of the  coverages  in the  amount
     described  above, the Owner shall so inform the Contractor in writing prior
     to commencement of the Work. The Contractor may then effect insurance which
     will  protect  the  interests  of  the   Contractor,   Subcontractors   and
     Sub-subcontractors  in the Work, and by  appropriate  Change Order the cost
     thereof shall be charged to the Owner.  If the Contractor is damaged by the
     failure  or neglect  of the Owner to  purchase  or  maintain  insurance  as
     described above,  without so notifying the Contractor in writing,  then the
     Owner shall bear all reasonable costs properly attributable thereto.

     11.4.1.3 If the property  insurance requires  deductibles,  the Owner shall
     pay costs not covered because of such deductibles.

     11.4.1.4 This property  insurance  shall cover  portions of the Work stored
     off the site, and also portions of the Work in transit.

     11.4.1.5  Partial  occupancy or use in accordance  with Paragraph 9.9 shall
     not commence until the insurance  company or companies  providing  property
     insurance have consented to such partial occupancy or use by endorsement or
     otherwise.  The Owner and the  Contractor  shall take  reasonable  steps to
     obtain  consent of the insurance  company or companies  and shall,  without
     mutual written consent, take no action with respect to partial occupancy or
     use that would cause cancellation, lapse or reduction of insurance.

     11.4.2  Boiler  and  Machinery  Insurance.  The Owner  shall  purchase  and
     maintain boiler and machinery  insurance required by the Contract Documents
     or by law,  which shall  specifically  cover such  insured  objects  during
     installation and until final acceptance by the Owner;  this insurance shall
     include   interests   of  the   Owner,   Contractor,   Subcontractors   and
     Sub-subcontractors in the Work, and the Owner and Contractor shall be named
     insureds.

     11.4.3  Loss of Use  Insurance.  The  Owner,  at the  Owner's  option,  may
     purchase and maintain such  insurance as will insure the Owner against loss
     of use of the  Owner's  property  due to fire  or  other  hazards,  however
     caused.  The Owner waives all rights of action  against the  Contractor for
     loss of use of the Owner's property,  including consequential losses due to
     fire or other hazards however caused.

     11.4.4 If the Contractor requests in writing that insurance for risks other
     than those described  herein or other special causes of loss be included in
     the property insurance policy,  the Owner shall, if possible,  include such
     insurance,  and the cost  thereof  shall be  charged to the  Contractor  by
     appropriate Change Order.
                                                                              *

     11.4.5  If  during  the  Project  construction  period  the  Owner  insures
     properties,  real or  personal  or  both,  at or  adjacent  to the  site by
     property insurance under policies separate from those insuring the Project,
     or if after  final  payment  property  insurance  is to be  provided on the
     completed  Project  through a policy or policies  other than those insuring
     the  Project  during the  construction  period,  the Owner  shall waive all
     rights in  accordance  with the terms of  Subparagraph  11.4.7 for  damages
     caused by fire or other  causes of loss covered by this  separate  property
     insurance.  All separate  policies shall provide this waiver of subrogation
     by endorsement or otherwise.

     11.4.6 Before an exposure to loss may occur,  the Owner shall file with the
     Contractor a copy of each policy that includes insurance coverages required
     by this Paragraph 11.4. Each policy shall contain all generally  applicable
     conditions,  definitions,  exclusions  and  endorsements  related  to  this
     Project.  Each policy shall contain a provision that the policy will not be
     canceled  or allowed to expire,  and that its limits  will not be  reduced,
     until at  least  30  days'  prior  written  notice  has  been  given to the
     Contractor.

     11.4.7 Waivers of  Subrogation.  The Owner and Contractor  waive all rights
     against (1) each other and any of their subcontractors, sub-subcontractors,
     agents and employees, each of the other, and (2) the Architect, Architect's
     consultants,  separate contractors  described in Article 6, if any, and any
     of their  subcontractors,  sub-subcontractors,  agents and  employees,  for
     damages  caused by fire or other  causes of loss to the  extent  covered by
     property  insurance  obtained  pursuant  to this  Paragraph  11.4 or  other
     property insurance  applicable to the Work, except such rights as they have
     to proceeds of such insurance held by the Owner as fiduciary.  The Owner or
     Contractor,  as  appropriate,  shall require of the Architect,  Architect's
     consultants,  separate contractors  described in Article 6, if any, and the
     subcontractors, sub-subcontractors, agents and employees of any of them, by
     appropriate  agreements,  written  where  legally  required  for  validity,
     similar  waivers  each in favor of other  parties  enumerated  herein.  The
     policies  shall  provide  such waivers of  subrogation  by  endorsement  or
     otherwise.  A waiver of  subrogation  shall be  effective as to a person or
     entity even though that  person or entity  would  otherwise  have a duty of
     indemnification,  contractual  or  otherwise,  did not  pay  the  insurance
     premium directly or indirectly, and whether or not the person or entity had
     an insurable interest in the property damaged.

     11.4.8 A loss insured under Owner's property insurance shall be adjusted by
     the Owner as fiduciary  and made payable to the Owner as fiduciary  for the
     insureds,  as their  interests may appear,  subject to  requirements of any
     applicable  mortgagee  clause and of Subparagraph  11.4.10.  The Contractor
     shall pay  Subcontractors  their just shares of insurance proceeds received
     by the  Contractor,  and by appropriate  agreements,  written where legally
     required for  validity,  shall require  Subcontractors  to make payments to
     their Sub-subcontractors in similar manner.

     11.4.9  If  required  in  writing  by a party  in  interest,  the  Owner as
     fiduciary  shall,  upon occurrence of an insured loss, give bond for proper
     performance  of the Owner's  duties.  The cost of  required  bonds shall be
     charged against proceeds received as fiduciary.  The Owner shall deposit in
     a separate account  proceeds so received,  which the Owner shall distribute
     in accordance  with such agreement as the parties in interest may reach, or
     in accordance  with an arbitration  award in which case the procedure shall
     be as  provided  in  Paragraph  4.6.  If after  such loss no other  special
     agreement  is made  and  unless  the  Owner  terminates  the  Contract  for
     convenience,  replacement  of damaged  property  shall be  performed by the
     Contractor  after  notification  of a Change in the Work in accordance with
     Article 7.

     11.4.10 The Owner as fiduciary shall have power to adjust and settle a loss
     with insurers unless one of the parties in interest shall object in writing
     within five days after  occurrence of loss to the Owner's  exercise of this
     power; if such objection is made, the dispute shall be resolved as provided
     in  Paragraphs  4.5 and 4.6. The Owner as fiduciary  shall,  in the case of
     arbitration, make settlement with insurers in accordance with directions of
     the  arbitrators.  If distribution of insurance  proceeds by arbitration is
     required, the arbitrators will direct such distribution.

     11.5     PERFORMANCE BOND AND PAYMENT BOND
     11.5.1 The Owner shall have the right to require the  Contractor to furnish
     bonds  covering  faithful  performance  of  the  Contract  and  payment  of
     obligations  arising  thereunder as stipulated in bidding  requirements  or
     specifically required in the Contract Documents on the date of execution of
     the Contract. The cost of such bonds shall be added to the Contract Sum.

     11.5.2 Upon the request of any person or entity appearing to be a potential
     beneficiary  of bonds  coveting  payment of  obligations  arising under the
     Contract,  the  Contractor  shall  promptly  furnish a copy of the bonds or
     shall permit a copy to be made.


ARTICLE 12 UNCOVERING AND CORRECTION OF WORK
     12.1     UNCOVERING OF WORK
     12.1.1 If a portion  of the Work is  covered  contrary  to the  Architect's
     request  or  to  requirements   specifically   expressed  in  the  Contract
     Documents,  it must, if required in writing by the Architect,  be uncovered
     for the Architect's examination and be replaced at the Contractor's expense
     without change in the Contract Time.

     12.1.2 If a portion of the Work has been covered  which the  Architect  has
     not  specifically  requested  to examine  prior to its being  covered,  the
     Architect  may  request to see such Work and it shall be  uncovered  by the
     Contractor.  If such Work is in  accordance  with the  Contract  Documents,
     costs of uncovering and replacement  shall, by appropriate Change Order, be
     at the Owner's expense. If such Work is not in accordance with the Contract
     Documents,  correction  shall be at the  Contractor's  expense  unless  the
     condition  was caused by the Owner or a separate  contractor in which event
     the Owner shall be responsible for payment of such costs.

     12.2     CORRECTION OF WORK
     12.2.1   BEFORE OR AFTER SUBSTANTIAL COMPLETION
     12.2.1.1  The  Contractor  shall  promptly  correct  Work  rejected  by the
     Architect  or  failing  to  conform  to the  requirements  of the  Contract
     Documents,  whether  discovered before or after Substantial  Completion and
     whether or not fabricated, installed or completed. Costs of correcting such
     rejected  Work,   including   additional   testing  and   inspections   and
     compensation  for the  Architect's  services  and expenses  made  necessary
     thereby, shall be at the Contractor's expense.

     12.2.2    AFTER SUBSTANTIAL COMPLETION
     12.2.2.1 In addition to the Contractor's  obligations  under Paragraph 3.5,
     if, within one year after the date of Substantial Completion of the Work or
     designated portion thereof or after the date for commencement of warranties
     established under Subparagraph  9.9.1, or by terms of an applicable special
     warranty required by the Contract Documents, any of the Work is found to be
     not in accordance  with the  requirements  of the Contract  Documents,  the
     Contractor  shall correct it promptly  after receipt of written notice from
     the Owner to do so unless the Owner has  previously  given the Contractor a
     written  acceptance  of such  condition.  The Owner  shall give such notice
     promptly after  discovery of the condition.  During the one-year period for
     correction  of Work, if the Owner fails to notify the  Contractor  and give
     the Contractor an opportunity to make the correction,  the Owner waives the
     rights to  require  correction  by the  Contractor  and to make a claim for
     breach of warranty.  If the Contractor fails to correct  nonconforming Work
     within a reasonable  time during that period  after  receipt of notice from
     the Owner or  Architect,  the  Owner  may  correct  it in  accordance  with
     Paragraph 2.4.

     12.2.2.2 The one-year  period for correction of Work shall be extended with
     respect to portions of Work first performed after Substantial Completion by
     the  period  of  time  between   Substantial   Completion  and  the  actual
     performance of the Work.

     12.2.2.3 The one-year  period for  correction of Work shall not be extended
     by corrective  Work performed by the Contractor  pursuant to this Paragraph
     12.2.

     12.2.3 The Contractor shall remove from the site portions of the Work which
     are not in accordance with the  requirements of the Contract  Documents and
     are neither corrected by the Contractor nor accepted by the Owner.

     12.2.4  The  Contractor  shall  bear the cost of  correcting  destroyed  or
     damaged  construction,  whether  completed or partially  completed,  of the
     Owner or separate  contractors  caused by the  Contractor's  correction  or
     removal of Work which is not in  accordance  with the  requirements  of the
     Contract Documents.

     12.2.5  Nothing  contained  in this  Paragraph  12.2 shall be  construed to
     establish a period of limitation  with respect to other  obligations  which
     the Contractor  might have under the Contract  Documents.  Establishment of
     the one-year  period for  correction  of Work as described in  Subparagraph
     12.2.2 relates only to the specific obligation of the Contractor to correct
     the Work, and has no  relationship  to the time within which the obligation
     to comply with the Contract Documents may be sought to be enforced,  nor to
     the time  within  which  proceedings  may be  commenced  to  establish  the
     Contractor's  liability with respect to the Contractor's  obligations other
     than specifically to correct the Work.

     12.3     ACCEPTANCE OF NONCONFORMING WORK
     12.3.1 If the Owner prefers to accept Work which is not in accordance  with
     the requirements of the Contract Documents,  the Owner may do so instead of
     requiring its removal and correction, in which case the Contract Sum may be
     reduced as appropriate  and equitable.  Such  adjustment  shall be effected
     whether or not final payment has been made.

     limitation of duties, obligations, rights and remedies otherwise imposed or
     available by law.

     13.4.2 No action or failure to act by the Owner,  Architect  or  Contractor
     shall  constitute  a waiver  of a right or duty  afforded  them  under  the
     Contract, nor shall such action or failure to act constitute approval of or
     acquiescence in a breach thereunder,  except as may be specifically  agreed
     in writing.

     such  tests,   inspections  and  approvals  with  an  independent   testing
     laboratory  or entity  acceptable  to the  Owner,  or with the  appropriate
     public  authority,  and shall bear all related costs of tests,  inspections

     determine that portions of the Work require additional testing,  inspection
     or approval not included under  Subparagraph  13.5.1,  the Architect  will,
     upon written  authorization from the Owner, instruct the Contractor to make
     arrangements  for such  additional  testing,  inspection  or approval by an
     entity acceptable to the Owner, and the Contractor shall give timely notice
     to the Architect of when and where tests and  inspections are to be made so
     that the Architect may be present for such procedures.  Such costs,  except
     as provided in Subparagraph 13.5.3, shall be at the Owner's expense.

     13.5.3  If such  procedures  for  testing,  inspection  or  approval  under
     Subparagraphs  13.5.1 and 13.5.2 reveal failure of the portions of the Work
     to comply with  requirements  established  by the Contract  Documents,  all

                  commence  to run and any  alleged  cause  of  action  shall be

ARTICLE 14 TERMINATION OR SUSPENSION OF THE CONTRACT


<PAGE>


     14.1     TERMINATION BY THE CONTRACTOR
     14.1.1 The Contractor may terminate the Contract if the Work is stopped for
     a period of 30  consecutive  days through no act or fault of the Contractor
     or a Subcontractor,  Sub-subcontractor  or their agents or employees or any
     other persons or entities  performing  portions of the Work under direct or
     indirect contract with the Contractor, for any of the following reasons:

              .1  issuance of an order of a court or other public authority
                  having jurisdiction which requires all Work to be stopped;

              .2  an act of government, such as a declaration of national 
                  emergency which requires all Work to be stopped;

              .3  because the Architect has not issued a Certificate for Payment
                  and  has  not  notified  the  Contractor  of  the  reason  for
                  withholding  certification as provided in Subparagraph  9.4.1,
                  or because the Owner has not made payment on a Certificate for
                  Payment within the time stated in the Contract Documents; or

              .4  the Owner has failed to furnish  to the  Contractor  promptly,
                  upon the Contractor's request, reasonable evidence as required
                  by Subparagraph 2.2.1; or

              .5  The Owner has failed to provide  information,  make decisions,
                  or furnish information required by the Contract Documents,  or
                  otherwise  is guilty of a  substantial  breach of the Contract
                  Documents.

     14.1.2 The  Contractor  may  terminate  the Contract if,  through no act or
     fault of the  Contractor  or a  Subcontractor,  Sub-subcontractor  or their
     agents or employees or any other persons or entities performing portions of
     the Work under direct or indirect  contract with the  Contractor,  repeated
     suspensions,  delays or  interruptions  of the entire  Work by the Owner as
     described in  Paragraph  14.3  constitute  in the  aggregate  more than 100
     percent of the total number of days scheduled for  completion,  or 120 days
     in any 365-day period, whichever is less.

     14.1.3 If one of the reasons  described  in  Subparagraph  14.1.1 or 14.1.2
     exists,  the  Contractor  may, upon seven days' written notice to the Owner
     and  Architect,  terminate  the Contract and recover from the Owner payment
     for Work executed and for proven loss with respect to materials, equipment,
     tools,  and  construction  equipment and  machinery,  including  reasonable
     overhead, profit and damages.

     14.1.4 If the Work is stopped for a period of 60  consecutive  days through
     no act or fault of the  Contractor  or a  Subcontractor  or their agents or
     employees  or any  other  persons  performing  portions  of the Work  under
     contract with the Contractor  because the Owner has persistently  failed to
     fulfill the Owner's  obligations under the Contract  Documents with respect
     to matters  important to the progress of the Work, the Contractor may, upon
     seven  additional  days'  written  notice to the  Owner and the  Architect,
     terminate   the  Contract  and  recover  from  the  Owner  as  provided  in
     Subparagraph 14.1.3.

     14.2     TERMINATION BY THE OWNER FOR CAUSE
     14.2.1 The Owner may terminate the Contract if the Contractor:

              .1  persistently or repeatedly refuses or fails to supply enough
                  properly skilled workers or proper materials;

              .2  fails to make payment to Subcontractors for materials or labor
                  in  accordance  with the  respective  agreements  between  the
                  Contractor and the Subcontractors;

              .3  persistently disregards laws, ordinances,  or rules,
                  regulations or orders of a public authority having 
                  jurisdiction; or

              .4  otherwise is guilty of substantial breach of a provision of
                  the Contract Documents.

     14.2.2 When any of the above reasons exist, the Owner,  upon  certification
     by the Architect that sufficient  cause exists to justify such action,  may
     without  prejudice  to any other  rights or remedies of the Owner and after
     giving the  Contractor  and the  Contractor's  surety,  if any, seven days'
     written notice,  terminate employment of the Contractor and may, subject to
     any prior rights of the surety:

              .1  take possession of the site and of all materials,  equipment,
                  tools, and construction equipment and machinery thereon
                  owned by the Contractor;

              .2  accept assignment of subcontracts pursuant to Paragraph 5.4;
                  and

              .3  finish the Work by  whatever  reasonable  method the Owner may
                  deem  expedient.  Upon  request of the  Contractor,  the Owner
                  shall furnish to the  Contractor a detailed  accounting of the
                  costs incurred by the Owner in finishing the Work.

     14.2.3 When the Owner terminates the Contract for one of the reasons stated
     in  Subparagraph  14.2.1,  the Contractor  shall not be entitled to receive
     further payment until the Work is finished.

     14.2.4 If the unpaid balance of the Contract Sum exceeds costs of finishing
     the Work, including  compensation for the Architect's services and expenses
     made  necessary  thereby,  and other damages  incurred by the Owner and not
     expressly  waived,  such excess  shall be paid to the  Contractor.  If such
     costs and damages exceed the unpaid balance,  the Contractor  shall pay the
     difference to the Owner.  The amount to be paid to the Contractor or Owner,
     as the case may be, shall be certified by the Architect,  upon application,
     and this obligation for payment shall survive termination of the Contract.

     14.3     SUSPENSION BY THE OWNER FOR CONVENIENCE
     14.3.1 The Owner may,  without  cause,  order the  Contractor in writing to
     suspend, delay or interrupt the Work in whole or in part for such period of
     time as the Owner may determine.

     14.3.2 The Contract Sum and Contract  Time shall be adjusted for  increases
     in the  cost and time  caused  by  suspension,  delay  or  interruption  as
     described  in  Subparagraph  14.3.1.  Adjustment  of the Contract Sum shall
     include profit. No adjustment shall be made to the extent:

              .1  that  performance  is,  was or would  have been so  suspended,
                  delayed  or   interrupted  by  another  cause  for  which  the
                  Contractor is responsible; or

              .2 that an equitable  adjustment  is made or denied under  another
                 provision of the Contract.

     14.4     TERMINATION BY THE OWNER FOR CONVENIENCE
     14.4.1 The Owner may, at any time,  terminate  the Contract for the Owner's
            convenience and without cause.

     14.4.2 Upon  receipt of written  notice from the Owner of such  termination
            for the Owner's convenience, the Contractor shall:

              .1  cease operations as directed by the Owner in the notice;

              .2  take actions necessary, or that the Owner may direct, for the
                  protection and preservation of the Work; and

              .3  except  for  Work  directed  to  be  performed  prior  to  the
                  effective date of termination stated in the notice,  terminate
                  all existing  subcontracts  and purchase orders and enter into
                  no further subcontracts and purchase orders.

     14.4.3  In case of  such  termination  for  the  Owner's  convenience,  the
     Contractor  shall be entitled to receive  payment  for Work  executed,  and
     costs  incurred  by  reason  of such  termination,  along  with  reasonable
     overhead and profit on the Work not executed.

                              ARTICLE 2 - Property

         2.1  Subject  to the terms and  conditions  of this  Agreement,  Seller
agrees to sell to Purchaser,  and Purchaser agrees to purchase from Seller,  the
following property (collectively, the "Property"):

                  2.1.1 Real Property.  The land described in Exhibit A attached
hereto (the "Land"),  together with (i) all improvements located thereon, if any
("Improvements"),  (ii)  all and  singular  the  rights,  benefits,  privileges,
easements,  tenements,  hereditaments,  and appurtenances  thereon or in anywise
appertaining  thereto  including,  without  limitation,  the  Drainage  Easement
described in Section 6.6 hereof, and (iii) without warranty,  all right,  title,
and  interest  of  Seller,  if any,  in and to all strips and gores and any land
lying in the bed of any street, road or alley, open or proposed,  adjoining such
Land (collectively, the "Real Property").

                  2.1.2   [Intentionally Omitted]
                  2.1.3 Tangible Personal Property. All of Seller's right, title
and  interest,  without  warranty,  in  the  equipment,   machinery,  furniture,
furnishings,  supplies and other tangible  personal  property,  if any, owned by
Seller  and  now or  hereafter  located  in and  used  in  connection  with  the
operation,  ownership  or  management  of the Real  Property,  but  specifically
excluding  any items of  personal  property  owned by  tenants at or on the Real
Property and further  excluding  any items of personal  property  owned by third
parties and leased to Seller (collectively, the "Tangible Personal Property").

                  2.1.4  Intangible  Personal  Property.  All of Seller's right,
title  and  interest,  if any,  without  warranty,  in all  intangible  personal
property related to the Real Property and the Improvements,  including,  without
limitation:  all trade names and trade marks  associated  with the Real Property
and the Improvements,  including  Seller's rights and interests,  if any, in the
name of the Real Property;  the plans and specifications and other architectural
and  engineering   drawings  for  the  Improvements,   if  any  (to  the  extent
assignable); warranties (to the extent assignable); contract rights, permits and
approvals related to the construction, operation, ownership or management of the
Real Property, including, without limitation, those listed on Exhibit D attached
hereto (but only to the extent  assignable and Seller's  obligations  thereunder
are expressly  assumed by Purchaser  pursuant to this  Agreement);  governmental
permits,  approvals  and  licenses,  if any  (to  the  extent  assignable);  and
telephone  exchange  numbers  (to  the  extent  assignable)   (collectively  the
"Intangible Personal Property").


                            ARTICLE 3 - Earnest Money

         3.1 Deposit and Investment of Earnest Money.  Within three (3) business
days after the Effective  Date,  Purchaser  shall deposit the Earnest Money with
Escrow Agent.  Escrow Agent shall invest the Earnest Money in government insured
interest-bearing  accounts  satisfactory  to  Seller  and  Purchaser,  shall not
commingle the Earnest Money with any funds of Escrow Agent or others,  and shall
promptly provide Purchaser and Seller with confirmation of the investments made.
Such account shall have no penalty for early  withdrawal,  and Purchaser accepts
all risks with regard to such account.

         3.2 Form; Failure to Deposit. The Earnest Money shall be in the form of
a  certified  or  cashier's  check  or the  wire  transfer  to  Escrow  Agent of
immediately  available U.S.  federal funds. If Purchaser fails to timely deposit
any portion of the Earnest  Money within the time periods  required,  Seller may
terminate  this  Agreement by written  notice to  Purchaser,  in which event the
parties hereto shall have no further rights or obligations hereunder, except for
rights and obligations which, by their terms, survive the termination hereof.

         3.3 Disposition of Earnest Money. The Earnest Money shall be applied as
a credit to the  Purchase  Price at Closing.  However,  if  Purchaser  elects to
terminate  this  Agreement  prior to the  expiration  of the  Inspection  Period
pursuant to Section  4.5,  Escrow  Agent  shall pay the  Earnest  Money (less an
amount equal to the Termination Reimbursement) to Purchaser one (1) business day
following  receipt of the Due Diligence  Termination  Notice from  Purchaser (as
long as the current  investment  can be liquidated and disbursed in one business
day). No notice to Escrow Agent from Seller shall be required for the release of
the Earnest  Money (less an amount equal to the  Termination  Reimbursement)  to
Purchaser by Escrow Agent if Purchaser  terminates  this  Agreement  pursuant to
Section 4.5.  Notwithstanding  anything  herein to the  contrary,  in all events
where the Earnest  Money is to be returned to  Purchaser,  other than in case of
Seller's  default  hereunder,  a  portion  of the  Earnest  Money  equal  to the
Termination  Reimbursement  shall be  delivered  to Seller as  reimbursement  to
Seller  pursuant  to  Section  12.20.  In the  event  of a  termination  of this
Agreement by either  Seller or Purchaser  for any reason other than  pursuant to
Section 4.5, Escrow Agent is authorized to deliver the Earnest Money (or portion
thereof) to the party hereto entitled to same pursuant to the terms hereof on or
before the fifth (5th)  business day  following  receipt by Escrow Agent and the
non-terminating party of written notice of such termination from the terminating
party,  unless the other party hereto notifies Escrow Agent that it disputes the
right of the other party to receive the Earnest Money (or portion  thereof).  In
such event, Escrow Agent may interplead the Earnest Money (or portion thereof in
dispute)  into a court of  competent  jurisdiction  in the  county  in which the
Earnest  Money has been  deposited.  All  attorneys'  fees and costs and  Escrow
Agent's costs and expenses incurred in connection with such  interpleader  shall
be assessed  against the party that is not awarded the Earnest Money,  or if the
Earnest  Money  is  distributed  in part to both  parties,  then in the  inverse
proportion of such distribution.


                            ARTICLE 4 - Due Diligence

         4.1 Due Diligence  Materials To Be Delivered.  To the extent such items

         Property; and 

 4.1.8   Leasing Commissions.  A list of contingent leasing commissions with 
         respect to the Property, if any.

 4.2     Due Diligence  Materials To Be Made  Available.  To the extent such
items are in  Seller's  possession  or in the  possession  of  Seller's  agents,
employees  or  contractors,   Seller  shall  make  available  to  Purchaser  for
Purchaser's  review,  at Seller's option at either the offices of Seller's Asset
Manager  or  property  manager  or at the  Property,  the  following  items  and
information  (the "Additional  Property  Information") on or before the Property
Information  Delivery Date, and Purchaser at its expense shall have the right to

4.2.1 [Intentionally Omitted]

4.2.2 [Intentionally Omitted]

4.2.3 [Intentionally Omitted]

4.2.4 Licenses, Permits and Certificates of Occupancy.
Licenses,  permits and  certificates  of  occupancy  relating to or  authorizing
construction or operation of a building or improvements on the property.

4.3  Physical  Due  Diligence.  Commencing  on the  Effective  Date and
continuing  until the Closing,  Purchaser  shall have  reasonable  access to the
Property  at all  reasonable  times for the  purpose  of  conducting  reasonably
necessary tests, including surveys and architectural,  engineering, geotechnical
and environmental  inspections and tests,  provided that (i) Purchaser must give
Seller  twenty-four  (24) hours' prior  telephone or written  notice of any such
inspection or test, and with respect to any intrusive  inspection or test (i.e.,
core sampling) must obtain  Seller's prior written  consent (which consent shall
not be  unreasonably  withheld or  conditioned),  (ii) prior to  performing  any
inspection or test,  Purchaser must deliver a certificate of insurance to Seller
evidencing that Purchaser and its contractors,  agents and representatives  have
in place reasonable  amounts of comprehensive  general  liability  insurance and
workers  compensation  insurance for its activities on the Property in terms and
amounts  reasonably  satisfactory  to Seller  covering any  accident  arising in
connection  with  the  presence  of  Purchaser,  its  contractors,   agents  and
representatives  on the Property,  which  insurance  shall name Seller and Asset
Manager as  additional  insureds  thereunder,  and (iii) all such tests shall be
conducted by Purchaser in compliance with Purchaser's responsibilities set forth
in Section 4.12 below.  Purchaser shall bear the cost of all such inspections or
tests and shall be responsible  for and act as the generator with respect to any
wastes  generated  by those  tests.  Subject to the  provisions  of Section  4.8
hereof, Purchaser or Purchaser's  representatives may meet with any governmental
authority  for any  good  faith,  reasonable  purpose  in  connection  with  the
transaction contemplated by this Agreement;  provided,  however,  Purchaser must
contact Seller at least forty-eight (48) hours in advance by telephone or fax to
inform  Seller  of  Purchaser's   intended  meeting  and  to  allow  Seller  the
opportunity to attend such meeting if Seller desires.

         During the  Inspection  Period  Purchaser  shall  review the  contracts
listed on Exhibit D attached  hereto and notify Seller prior to the  termination
of the  Inspection  Period as to which  contracts  Purchaser has elected to take
assignment  of and  assume  obligations  thereunder  arising  from and after the
Closing Date (the "Assumed  Contracts").  It shall be a condition to Purchaser's
obligation  to close on the Closing Date that any and all  consents  required in
connection  with the  assignment  and  assumption  of the Assumed  Contracts  be
delivered on the Closing Date.

4.4      [Intentionally Omitted]

4.5    Due  Diligence/Termination  Right. Purchaser shall have through the
last  day of the  Inspection  Period  in  which  to (i)  examine,  inspect,  and
investigate  the Property  Information and the Additional  Property  Information
(collectively,  the "Property  Documents")  and the Property and, in Purchaser's
sole and absolute  judgment and  discretion,  determine  whether the Property is
acceptable to Purchaser, (ii) obtain all necessary internal approvals, and (iii)
satisfy all other contingencies of Purchaser,  including those listed in Section
6.1.4  below.  Notwithstanding  anything  to the  contrary  in  this  Agreement,
Purchaser  may  terminate  this  Agreement for any reason or no reason by giving
written  notice of  termination  to Seller and Escrow Agent (the "Due  Diligence
Termination  Notice")  on or before the last day of the  Inspection  Period.  If
Purchaser does not give a Due Diligence Termination Notice, this Agreement shall
continue in full force and effect,  Purchaser shall be deemed to have waived its
right to terminate  this  Agreement  pursuant to this Section 4.5, and Purchaser
shall be deemed to have  acknowledged  that it has received or had access to all
Property  Documents and conducted all inspections and tests of the Property that
it considers important.

4.6 Return of Documents and Reports.  If this Agreement  terminates for
any reason other than  Seller's  default  hereunder,  Purchaser  shall  promptly
return  and/or  deliver to Seller all  Property  Documents  and copies  thereof.
Additionally,  if this  Agreement  terminates for any reason other than Seller's
default,  then  Purchaser  must  deliver  to Seller  copies  of all third  party
reports, investigations and studies, other than economic analyses (collectively,
the  "Reports"  and,  individually,   a  "Report")  prepared  for  Purchaser  in
connection with its due diligence  review of the Property.  The Reports shall be
delivered  to  Seller  without  any   representation   or  warranty  as  to  the
completeness  or accuracy of the Reports or any other matter  relating  thereto,
and Seller shall have no right to rely on any Report without the written consent
of the party  preparing  same.  Purchaser's  obligation  to deliver the Property
Documents  and the  Reports to Seller  shall  survive  the  termination  of this
Agreement.

4.7      [Intentionally Omitted]

4.8 Proprietary  Information;  Confidentiality.  Purchaser acknowledges
that  the  Property  Documents  are  proprietary  and  confidential  and will be
delivered to Purchaser solely to assist Purchaser in determining the feasibility
of purchasing the Property.  Purchaser shall not use the Property  Documents for
any purpose other than as set forth in the preceding  sentence.  Purchaser shall
not disclose the  contents to any person other than to those  persons  providing
financing or who are  responsible for determining the feasibility of Purchaser's
acquisition of the Property and who have agreed to preserve the  confidentiality
of  such  information  as  required  hereby  (collectively,  "Permitted  Outside
Parties"). At any time and from time to time, within two (2) business days after
Seller's  request,  Purchaser  shall  deliver to Seller a list of all parties to
whom Purchaser has provided any Property Documents or any information taken from
the Property Documents. Purchaser shall not divulge the contents of the Property
Documents  and  other   information   except  in  strict   accordance  with  the
confidentiality standards set forth in this Section 4.8. In permitting Purchaser
to review the Property Documents or any other information, Seller has not waived
any privilege or claim of  confidentiality  with respect  thereto,  and no third
party benefits or  relationships  of any kind,  either express or implied,  have
been offered, intended or created.

4.9 No  Representation  or Warranty by Seller . Purchaser  acknowledges
that, except as expressly set forth in this Agreement,  neither Seller nor Asset
Manager has made nor makes any warranty or  representation  regarding the truth,
accuracy or  completeness  of the Property  Documents or the source(s)  thereof.
Purchaser further  acknowledges  that some if not all of the Property  Documents
were prepared by third parties other than Seller and Asset  Manager.  Seller and
Asset Manager expressly  disclaim any and all liability for  representations  or
warranties,  express or implied,  statements of fact and other matters contained
in such  information,  or for omissions from the Property  Documents,  or in any
other written or oral communications transmitted or made available to Purchaser.
Purchaser  shall rely  solely  upon its own  investigation  with  respect to the
Property, including, without limitation, the Property's physical,  environmental
or economic  condition,  compliance  or lack of compliance  with any  ordinance,
order,  permit or regulation or any other attribute or matter relating  thereto.
Seller and Asset Manager have not undertaken any independent investigation as to
the truth,  accuracy or completeness of the Property Documents and are providing
the Property Documents solely as an accommodation to Purchaser.

4.0  Purchaser's  Responsibilities.  In  conducting  any  inspections,
investigations or tests of the Property and/or Property Documents, Purchaser and
its agents and  representatives  shall: (i) not interfere with the operation and
maintenance of the Property; (ii) not damage any part of the Property; (iii) not
injure or  otherwise  cause  bodily  harm to  Seller,  Asset  Manager,  or their
respective agents, guests, invitees, contractors and employees or any tenants or
their guests or invitees;  (iv) comply with all applicable  laws; (v) not permit
any liens to attach to the Real Property by reason of the exercise of its rights
hereunder;  (vi) repair any damage to the Real  Property  resulting  directly or
indirectly from any such  inspection or tests;  and (vii) not reveal or disclose
prior  to  Closing  any  information   obtained  during  the  Inspection  Period
concerning  the  Property  and the  Property  Documents to anyone other than the
Permitted Outside Parties, in accordance with the confidentiality  standards set
forth in Section 4.8 above, or except as may be otherwise required by law.

4.11  Purchaser's  Agreement to Indemnify.  Purchaser  indemnifies  and
holds  Seller and Asset  Manager  harmless  from and  against any and all liens,
claims,  causes  of  action,   damages,   liabilities  and  expenses  (including
reasonable  attorneys'  fees) arising out of  Purchaser's  inspections  or tests
permitted  under this  Agreement or any violation of the  provisions of Sections
4.3, 4.8 and 4.10; provided,  however, the indemnity shall not extend to protect
Seller from any  pre-existing  liabilities  for  matters  merely  discovered  by
Purchaser  (i.e.,  latent  environmental  contamination)  so long as Purchaser's
actions do not aggravate any  pre-existing  liability of Seller.  Purchaser also
indemnifies  and holds any tenant  harmless from and against any and all claims,
causes of action, damages, liabilities and expenses which such tenant may suffer
or incur due to Purchaser's  breach of its obligation under Section 4.8 above to
maintain the confidential  nature of any Property Documents or other information
relative to such tenant.  Purchaser's  obligations under this Section 4.11 shall
survive the termination of this Agreement and shall survive the Closing.
4.12 Environmental Studies;  Seller's Right to Terminate. As additional
consideration for the transaction contemplated in this Agreement, Purchaser must
provide to  Seller,  immediately  following  the  receipt of same by  Purchaser,
copies of any and all reports,  tests or studies  involving  contamination of or
other  environmental  concerns  relating  to the  Property;  provided,  however,
Purchaser  shall  have no  obligation  to cause any such  tests or studies to be
performed on the Property.  Seller  acknowledges that Purchaser has not made and
does not make any warranty or representation  regarding the truth or accuracy of
any such studies or reports. Notwithstanding Section 4.11 above, Purchaser shall
have no liability or  culpability  of any nature as a result of having  provided
such  information  to Seller  or as a result of  Seller's  reliance  thereon  or
arising out of the fact that Purchaser  merely  conducted such tests or studies,
so long as Purchaser's  actions do not aggravate any  pre-existing  liability of
Seller. In the event that such reports,  tests or studies indicate the existence
or reasonable  potential  existence of any  contamination  of any portion of the
Property  that is not  disclosed in the Property  Documents and that is material
(meaning  that  the  reasonably  estimated  cost  of  remediation  and/or  other
liability  associated  therewith,   as  determined  by  Seller's   environmental
consultants,  exceeds $100,000.00),  then Seller may terminate this Agreement by
giving written notice to Purchaser within ten (10) business days after Purchaser
has provided Seller with copies of such reports, tests or studies, whereupon the
Earnest Money (less the Termination  Reimbursement,  which shall be delivered to
Seller)  shall be  returned  to  Purchaser,  the  parties  shall have no further
obligations   hereunder  except  for  obligations  that  expressly  survive  the
termination  hereof,  and Seller  shall pay to  Purchaser an amount equal to the
lesser of (A) Purchaser's actual out-of-pocket expenditures incurred directly in
connection  with  negotiating  this  Agreement  and/or  conducting due diligence
activities  contemplated  hereunder,  or (B)  Twenty-Five  Thousand  and  No/100
Dollars ($25,000.00), provided, however, that Purchaser must make written demand
of Seller  for such  reimbursement  and  provide  Seller  reasonable  supporting
documentation of actual  expenditures within thirty (30) days of the termination
of this  Agreement,  and if Purchaser  fails to provide such written  demand and
supporting  documentation  within such thirty  (30) day period,  then  Purchaser
shall be deemed to have  forever  waived  its right to recover  any amount  from
Seller.


                          ARTICLE 5 - Title and Survey

5.1  Title  Commitment.  Purchaser  shall  cause  to  be  prepared  and
delivered  to Seller on or before  the Title  Commitment  Delivery  Date:  (i) a
current  commitment for title insurance or preliminary  title report (the "Title
Commitment")  issued by the Title  Company,  in the amount of the Purchase Price
and on a ALTA 1992  Standard  Form  commitment,  with  Purchaser as the proposed
insured,  and (ii) copies of all  documents  of record  referred to in the Title
Commitment as exceptions to title to the Property.

5.2  New or Updated  Survey.  Purchaser may elect to obtain a new survey
or revise,  modify,  or re-certify an existing survey ("Survey") as necessary in
order for the Title Company to delete the survey exception from the Title Policy
or to otherwise satisfy Purchaser's objectives.

5.3 Title Review. During the Title and Survey Review Period,  Purchaser
shall review title to the Property as disclosed by the Title  Commitment and the
Survey.  Seller  shall  have no  obligation  to  cure  title  objections  except
financing liens of an ascertainable  amount created by, under or through Seller,
which liens  Seller  shall  cause to be  released  at or prior to Closing  (with
Seller  having the right to apply the  Purchase  Price or a portion  thereof for
such purpose),  and Seller shall deliver the Property free and clear of any such
financing liens.  Seller further agrees to remove any exceptions or encumbrances
to title which are  voluntarily  created by,  under or through  Seller after the
Effective Date without  Purchaser's  consent.  The term  "Permitted  Exceptions"
shall mean: the specific exceptions  (excluding  exceptions that are part of the
promulgated title insurance form) in the Title Commitment that the Title Company
has not agreed to remove  from the Title  Commitment  as of the end of the Title
and Survey  Review  Period and that Seller is not required to remove as provided
above; matters created by, through or under Purchaser; items shown on the Survey
which have not been removed as of the end of the Inspection Period;  real estate
taxes not yet due and payable;  tenants under any leases;  and any licensees not
terminated as of Closing.

5.4  Delivery of Title  Policy at Closing.  In the event that the Title
Company  does not issue at  Closing,  or  unconditionally  commit at  Closing to
issue,  to  Purchaser,  an owner's  title  policy in  accordance  with the Title
Commitment,  insuring good,  clear and  marketable  title to the Property in the
amount of the  Purchase  Price,  subject  only to the  standard  exceptions  and
exclusions from coverage  contained in such policy and the Permitted  Exceptions
(the  "Title  Policy"),  Purchaser  shall  have  the  right  to  terminate  this
Agreement, in which case the Earnest Money (less the Termination  Reimbursement,
which shall be delivered to Seller) shall be  immediately  returned to Purchaser
and the parties hereto shall have no further rights or  obligations,  other than
those that by their terms survive the termination of this Agreement.


      ARTICLE 6 - Operations, Risk of Loss, and Covenants Prior to Closing

         6.1 Ongoing Operations. From the Effective Date through Closing, Seller
will not enter  into any  contract  that  will be an  obligation  affecting  the
Property  subsequent  to the  Closing,  except  contracts  entered  into  in the
ordinary  course of business that are  terminable  without cause and without the
payment of any  termination  penalty on not more than  thirty  (30) days'  prior
notice.

         6.2      [Intentionally Omitted]

         6.3 Condemnation.  If proceedings in eminent domain are instituted with
respect to the Property or any portion thereof, Purchaser may, at its option, by
written  notice to Seller  given  within  ten (10) days  after  Seller  notifies
Purchaser  of such  proceedings  (and if  necessary  the  Closing  Date shall be
automatically  extended to give  Purchaser the full ten-day  period to make such
election), either: (i) terminate this Agreement, in which case the Earnest Money
(less the Termination  Reimbursement,  which shall be delivered to Seller) shall
be  immediately  returned  to  Purchaser  and the parties  hereto  shall have no
further rights or obligations,  other than those that by their terms survive the
termination of this Agreement,  or (ii) proceed under this  Agreement,  in which
event Seller shall, at the Closing,  assign to Purchaser its entire right, title
and interest in and to any condemnation award, and Purchaser shall have the sole
right after the Closing to  negotiate  and  otherwise  deal with the  condemning
authority in respect of such matter.  If Purchaser  does not give Seller written
notice of its election within the time required  above,  then Purchaser shall be
deemed to have elected option (ii) above.

         6.4  New  Subdivision  Plan.  The  Property  is  comprised  of  (i)  an
approximate  one (1) acre  portion  (the  "One  Acre  Portion")  out of a parcel
currently  containing  approximately  9.77  acres  and  known  as  5  Omni  Way,
Chelmsford,  Massachusetts  and described as Lot 2A on Exhibit A attached hereto
(the "5 Omni Way  Parcel"),  said 5 Omni Way Parcel  being a  registered  parcel
subject to the jurisdiction of the Land Court of Massachusetts,  and (ii) all of
a parcel  containing  approximately  9.16 acres and known as 297 Billerica Road,
Chelmsford, Massachusetts, and described as Lot 1 A on Exhibit A attached hereto
(the  "Non-Registered  Parcel"),  which is not a  registered  parcel.  It is the
parties'  intent  that the One Acre  Portion be  subdivided  from the 5 Omni Way
Parcel pursuant to a new subdivision plan (the "New Subdivision Plan") that must
be  approved  by the Land Court of  Massachusetts.  Seller has  heretofore  been
pursuing  approval  of  the  New  Subdivision  Plan  and  will  continue  to use
reasonable  efforts  to  obtain  such  approval  prior to the  Outside  Date for
Closing.  Among other things, such approval will require that the current tenant
of the 5 Omni Way Parcel, Sun Microsystems, Inc. ("Sun Microsystems"),  agree to
release the One Acre Portion from its  leasehold  estate by the  execution of an
amendment to its existing lease, and further that Seller's current  mortgagee of
the 5 Omni Way Parcel  ("Seller's  Lender") agree to release the One Acre Parcel
from the lien of its mortgage.  Seller shall use reasonable efforts to cause Sun
Micro  Systems  to agree to  release  the One Acre  Portion  from its  leasehold
estate,  and to cause  Seller's  Lender to release the One Acre Portion from the
lien of its  mortgage,  prior to the Outside Date for Closing,  but Seller shall
not be obligated to incur any material cost or expense  whatsoever in connection
therewith,  except  that  Seller  agrees to pay the  release  price  required by
Seller's  Lender,  and  Seller  shall  further  pay any  reasonable,  usual  and
customary  legal fees of Seller's  counsel (but not any legal fees or other fees
that may be  charged  by  Seller's  Lender)  in  connection  with said  release.
Purchaser shall reasonably cooperate with Seller in satisfying the conditions of
this  paragraph,  and shall  reimburse  Seller  for its costs  and  expenses  in
connection  therewith  in  accordance  with the terms of Section  12.20  hereof.
Approval of the New Subdivision  Plan is a condition  precedent to both Seller's
and Purchaser's  obligation to close in accordance with Subsection 7.2.4 hereof.
The  provisions  of  Section  12.22  hereof  shall  apply  with  respect to this
paragraph.

         6.5 New Lease for 2 Omni Way. Seller and Purchaser  intend to negotiate
and enter into a new lease agreement (the "2 Omni Way Lease")  pursuant to which
Purchaser, as tenant, will lease from Seller, as landlord, that certain building
owned by Seller  adjacent to the Property  and known as 2 Omni Way,  Chelmsford,
Massachusetts  (the "2 Omni Way Building").  Seller and Purchaser will negotiate
in good faith and use  reasonable  efforts to execute  and enter into the 2 Omni
Way Lease prior to the  Outside  Date for  Closing.  The 2 Omni Way Lease is and
shall be subject to and  conditioned  on (i)  termination  of the existing lease
agreement between Seller and Sun Microsystems pursuant to which Sun Microsystems
currently leases from Seller the 2 Omni Way Building, and (ii) vacation of the 2
Omni Way Building by Sun  Microsystems.  Seller shall use reasonable  efforts to
cause  Sun  Microsystems  to  terminate  its  lease  and  vacate  the 2 Omni Way
Building,  but  Seller  shall not be  obligated  to incur any  material  cost or
expense  whatsoever  in  connection  therewith.  Satisfaction  of the  foregoing
requirements  is a condition to  Purchaser's  obligation  to close in accordance
with Subsection 7.2.5 hereof,  and if by the Outside Date for Closing the 2 Omni
Way Lease has not been executed and entered into by Seller and Purchaser  and/or
if Sun  Microsystems  has not  terminated  its lease and  vacated the 2 Omni Way
Building,  then Purchaser shall have the right to terminate this  Agreement,  in
which event the Earnest Money (less the Termination  Reimbursement,  which shall
be  delivered  to Seller)  shall be returned to  Purchaser.  The  provisions  of
Section 12.22 hereof shall apply with respect to this paragraph.

         6.6  Drainage  Easement;   Sun  Microsystems'   Consent.  Both  parties
acknowledge  the need for a  non-exclusive  drainage  easement  benefitting  the
Property  (the  "Drainage  Easement")  over and  across the 5 Omni Way Parcel as
shown on the Plan attached  hereto as Exhibit F-1.  Seller and  Purchaser  agree
that the form of Drainage Easement shall be substantially in the form of Exhibit
F-2 hereto.  Final approval of the Drainage Easement is and shall be conditioned
on the current tenant of the 5 Omni Way Parcel,  Sun Microsystems,  and Seller's
Lender  each  consenting  in writing to the  Drainage  Easement  and on Seller's
Lender  subordinating  its  lien to the  Drainage  Easement.  Seller  shall  use
reasonable efforts to cause Sun Microsystems and Seller's Lender each to consent
in writing to the Drainage Easement (and Seller's Lender to subordinate its lien
to the Drainage  Easement)  prior to the Outside  Date for  Closing,  but Seller
shall not be obligated  to incur any cost or expense  whatsoever  in  connection
therewith. If the foregoing requirements have been satisfied as of Closing, then
at Closing  Seller shall  execute the Drainage  Easement  document and have same
recorded  in the real  property  records of the county in which the  Property is
located.   Satisfaction  of  the  foregoing   requirements  is  a  condition  to
Purchaser's  obligation to close in accordance with Subsection 7.2.6 hereof, and
if by the  Outside  Date for Closing the  foregoing  requirements  have not been
satisfied,  then Purchaser shall have the right to terminate this Agreement,  in
which event the Earnest Money (less the Termination  Reimbursement,  which shall
be  delivered  to Seller)  shall be returned to  Purchaser.  The  provisions  of
Section 12.22 hereof shall apply with respect to this paragraph.

         6.7 Building Permit.  Purchaser,  at Purchaser's sole cost and expense,
shall, as soon as reasonably possible after the Effective Date, make application
with the appropriate  municipal  authorities to obtain a building permit for the
construction  of a three (3)  story,  approximate  127,000  square  feet  office
building  on  the  Property;   provided,   however,   prior  to  submitting  any
application,  filing or any other  document in connection  therewith,  Purchaser
shall submit same to Seller for Seller's  approval,  which approval shall not be
unreasonably  withheld  or  delayed so long as  Purchaser  is  otherwise  not in
default under the terms of this Agreement. Purchaser shall diligently pursue the
building permit and use all reasonable  efforts to obtain said permit as soon as
reasonably  possible.  Seller shall reasonably  cooperate with Purchaser in this
regard,  but shall not be obligated to incur any cost or expense  whatsoever  in
connection therewith.  The issuance of a building permit shall be a condition to
Purchaser's  obligation to close, and if Purchaser has not obtained the building
permit or is otherwise  not  satisfied  with the status of the  building  permit
process prior to the Outside  Closing Date,  then Purchaser shall have the right
to  terminate  this  Agreement,  in which  event  the  Earnest  Money  (less the
Termination Reimbursement, which shall be delivered to Seller) shall be returned
to Purchaser.


                               ARTICLE 7 - Closing

ability to perform its obligations under this Agreement.

                  7.2.4 Release of One Acre Portion;  New Subdivision  Plan. The
releases from Sun  Microsystems  and Seller's Lender shall have been obtained in
accordance  with  Section  6.4,  and the New  Subdivision  Plan  shall have been
approved by the Land Court of Massachusetts.  Notwithstanding anything herein to
the contrary,  if this  condition has not been satisfied by the Outside Date for
Closing,  then either party may  terminate  this  Agreement,  in which event the
Earnest  Money (less an amount  equal to the  Termination  Reimbursement,  which
shall be delivered to Seller) shall be delivered to Purchaser.

         In  addition  to the  foregoing  conditions,  the  following  shall  be
additional  conditions to Purchaser's  obligation to consummate the transactions
contemplated hereunder:

                  7.2.5 New Lease  for 2 Omni  Way.  The 2 Omni Way Lease  shall
have been  executed  and  entered  into by Seller and  Purchaser,  and the other
conditions set forth in Section 6.5 shall have been  satisfied.  Notwithstanding

event the Earnest Money (less an amount equal to the Termination  Reimbursement,
which shall be delivered to Seller) shall be delivered to Purchaser.

                  7.2.6  Consent to  Drainage  Easement.  Sun  Microsystems  and

         So long as a party is not in default  hereunder,  if any  condition  to
such  party's  obligation  to proceed  with the Closing  hereunder  has not been
satisfied as of the Closing  Date (or such earlier date as is provided  herein),
such party may, in its sole  discretion,  terminate this Agreement by delivering
written notice to the other party on or before the Closing Date (or such earlier
date as is provided  herein),  or elect to close (or to permit any such  earlier
termination  deadline  to pass)  notwithstanding  the  non-satisfaction  of such
condition,  in which  event such party  shall be deemed to have  waived any such
condition.  In the event  such  party  elects  to close  (or to permit  any such
earlier termination  deadline to pass),  notwithstanding the non-satisfaction of
such condition,  said party shall be deemed to have waived said  condition,  and
there shall be no  liability  on the part of any other party hereto for breaches
of  representations  and  warranties  of which the party  electing  to close had

                  9.2.1  Organization  and  Authority.  Purchaser  has been duly
organized and is validly existing as a corporation in good standing in the State
of  Delaware  and is  qualified  to do  business  in the state in which the Real
Property is located. Purchaser has the full right and authority and has obtained
any and all consents  required to enter into this Agreement and to consummate or
cause to be consummated the transactions contemplated hereby. This Agreement has
been,  and all of the documents to be delivered by Purchaser at the Closing will
be,  authorized and properly  executed and constitute,  or will  constitute,  as
appropriate,  the valid and binding  obligation  of  Purchaser,  enforceable  in
accordance with their terms.

                  9.2.2 Conflicts and Pending  Action.  There is no agreement to
which  Purchaser  is a party or to  Purchaser's  knowledge  binding on Purchaser
which is in  conflict  with this  Agreement.  There is no  action or  proceeding
pending  or,  to  Purchaser's  knowledge,  threatened  against  Purchaser  which
challenges or impairs  Purchaser's ability to execute or perform its obligations
under this Agreement.

         9.3 Survival of Representations and Warranties. The representations and
warranties set forth in this Article 9 are made as of the date of this Agreement
and are remade as of the Closing  Date and shall not be deemed to be merged into
or waived by the  instruments  of Closing,  but shall  survive the Closing for a
period of twelve (12) months (the "Survival Period"). Terms such as "to Seller's
knowledge," "to the best of Seller's  knowledge" or like phrases mean the actual
present and conscious  awareness or knowledge of Paul Douglas,  asset manager of
the  Property  ("Asset  Manager's  Employee"),  without  any duty of  inquiry or
investigation;  provided that so qualifying Seller's knowledge shall in no event
give rise to any personal  liability on the part of Asset Manager's  Employee or
any other officer or employee of Seller or its Asset Manager,  on account of any
breach of any  representation  or warranty made by Seller herein.  Said terms do
not include constructive  knowledge,  imputed knowledge,  or knowledge Seller or
such persons do not have but could have obtained  through further  investigation
or inquiry.  No broker,  agent, or party other than Seller is authorized to make
any representation or warranty for or on behalf of Seller. Each party shall have
the right to bring an action against the other on the breach of a representation
or  warranty  hereunder,  but only on the  following  conditions:  (i) the party
bringing  the action for breach  first  learns of the breach  after  Closing and
files such action within the Survival Period,  and (ii) neither party shall have
the  right to bring a cause  of  action  for a  breach  of a  representation  or
warranty unless the damage to such party on account of such breach (individually
or when combined with damages from other breaches) equals or exceeds $15,000.00.
Neither  party  shall  have any  liability  after  Closing  for the  breach of a
representation  or  warranty  hereunder  of which the  other  party  hereto  had
knowledge  as  of  Closing.  Furthermore,  Purchaser  agrees  that  the  maximum
liability  of Seller for the  alleged  breach of any or all  representations  or
warranties set forth in this Agreement is limited to $250,000.00. The provisions
of this Section 9.3 shall survive the Closing. Any breach of a representation or
warranty that occurs prior to Closing shall be governed by Article 10.


                        ARTICLE 10 - Default and Remedies

         10.1 Seller's  Remedies.  If Purchaser fails to perform its obligations
pursuant to this  Agreement at or prior to Closing for any reason except failure
by  Seller  to  perform  hereunder,  or if prior to  Closing  any one or more of
Purchaser's  representations or warranties are breached in any material respect,
Seller  shall be  entitled,  as its sole remedy  (except as provided in Sections
4.11,  8.6, 10.3 and 10.4 hereof),  to terminate  this Agreement and recover the
Earnest Money as liquidated damages and not as penalty,  in full satisfaction of
claims against  Purchaser  hereunder.  Seller and Purchaser  agree that Seller's
damages resulting from Purchaser's default are difficult, if not impossible,  to
determine  and the Earnest  Money is a fair  estimate of those damages which has
been  agreed to in an effort to cause the amount of such  damages to be certain.
Notwithstanding  anything in this Section 10.1 or in Exhibit G to the  contrary,
in the event of Purchaser's default and a termination of this Agreement,  Seller
shall have all remedies  available at law or in equity in the event Purchaser or
any party  related to or  affiliated  with  Purchaser is asserting any claims or
right to the Property that would  otherwise  delay or prevent Seller from having
clear,  indefeasible and marketable  title to the Property.  In all other events
Seller's  remedies shall be limited to those  described in this Section 10.1 and
Sections 4.11, 8.6, 10.3 and 10.4 hereof.

         10.2 Purchaser's  Remedies.  If Seller fails to perform its obligations
pursuant to this Agreement for any reason except failure by Purchaser to perform
hereunder, or if prior to Closing any one or more of Seller's representations or
warranties are breached in any material  respect,  Purchaser shall elect, as its
sole remedy,  either to (i)  terminate  this  Agreement by giving  Seller timely
written  notice of such election  prior to or at Closing and recover the Earnest
Money, (ii) enforce specific performance,  or (iii) waive said failure or breach
and  proceed  to  Closing.  Notwithstanding  anything  herein  to the  contrary,
Purchaser  shall be  deemed to have  elected  to  terminate  this  Agreement  if
Purchaser  fails to  deliver  to Seller  written  notice of its intent to file a
claim or assert a cause of action for specific  performance against Seller on or
before twenty (20) business days following the scheduled Closing Date or, having
given  such  notice,  fails to file a lawsuit  asserting  such claim or cause of
action in the county in which the  Property is located  within  three (3) months
following the scheduled Closing Date.  Purchaser's  remedies shall be limited to
those  described in this Section  10.2 and  Sections  10.3 and 10.4 hereof.  If,
however,  the  equitable  remedy  of  specific  performance  is  not  available,
Purchaser  may seek any other  right or remedy  available  at law or in  equity;
provided,  however, that in no event shall Seller's liability exceed the Earnest
Money, if it is not refunded to Purchaser), plus the lesser of (i) $75,000.00 or
(ii) the actual reasonable out-of-pocket expenses incurred by Purchaser and paid
(A) to  Purchaser's  attorneys  in  connection  with  the  negotiation  of  this
Agreement  and (B) to unrelated  and  unaffiliated  third party  consultants  in
connection   with  the   performance   of   examinations,   inspections   and/or
investigations  pursuant to Article 4. For purposes of this provision,  specific
performance  shall be considered  not available to Purchaser  only if a court of
competent  jurisdiction  (or  an  arbitrator,   as  per  Exhibit  G)  determines
conclusively that Purchaser is entitled to specific performance on the merits of
its claim but said court or arbitrator is unable to enforce specific performance
due to reasons beyond the control of the court or arbitrator.  IN NO EVENT SHALL
SELLER'S DIRECT OR INDIRECT PARTNERS,  SHAREHOLDERS,  OWNERS OR AFFILIATES,  ANY
OFFICER,  DIRECTOR,  EMPLOYEE OR AGENT OF THE  FOREGOING,  OR ANY  AFFILIATE  OR
CONTROLLING  PERSON THEREOF HAVE ANY LIABILITY FOR ANY CLAIM, CAUSE OF ACTION OR
OTHER  LIABILITY  ARISING OUT OF OR RELATING TO THIS  AGREEMENT OR THE PROPERTY,
WHETHER BASED ON CONTRACT, COMMON LAW, STATUTE, EQUITY OR OTHERWISE.

         10.3  Attorneys'  Fees.  In the event either  party  hereto  employs an
attorney in  connection  with claims by one party against the other arising from
the  operation  of  this  Agreement,  the  non-prevailing  party  shall  pay the
prevailing  party all reasonable fees and expenses,  including  attorneys' fees,
incurred in connection with such claims.

         10.4 Other Expenses. If this Agreement is terminated due to the default
of a party,  then the  defaulting  party  shall pay any fees or  charges  due to
Escrow  Agent for holding the Earnest  Money as well as any escrow  cancellation
fees or charges and any fees or charges due to the Title Company for preparation
and/or cancellation of the Title Commitment.


                 ARTICLE 11 - Disclaimers, Release and Indemnity

         11.1  Disclaimers  By  Seller.  Except as  expressly  set forth in this
Agreement, it is understood and agreed that Seller and Asset Manager have not at
any  time  made and are not now  making,  and they  specifically  disclaim,  any

respect to the Property.

         11.2 Sale "As Is,  Where Is."  Purchaser  acknowledges  and agrees that
upon  Closing,  Seller shall sell and convey to Purchaser  and  Purchaser  shall
accept the Property  "AS IS,  WHERE IS, WITH ALL  FAULTS,"  except to the extent
expressly  provided  otherwise in this  Agreement  and any document  executed by
Seller and  delivered to Purchaser at Closing.  Except as expressly set forth in
this  Agreement,  Purchaser  has not relied and will not rely on, and Seller has
not made and is not liable for or bound by, any  express or implied  warranties,
guarantees,  statements,   representations  or  information  pertaining  to  the
Property  or  relating  thereto  (including  specifically,  without  limitation,
Property  information packages distributed with respect to the Property) made or
furnished  by Seller,  the Asset  Manager of the  Property,  or any real  estate
broker,  agent or third party representing or purporting to represent Seller, to
whomever made or given, directly or indirectly,  orally or in writing. Purchaser
represents that it is a knowledgeable,  experienced and sophisticated  purchaser
of real estate and that, except as expressly set forth in this Agreement,  it is
relying  solely on its own  expertise  and that of  Purchaser's  consultants  in
purchasing  the  Property  and shall  make an  independent  verification  of the

conduct such inspections and  investigations  of the Property as Purchaser deems
necessary,  including,  but not  limited  to,  the  physical  and  environmental
conditions  thereof,  and shall rely upon same.  By  failing to  terminate  this
Agreement  prior  to  the  expiration  of  the  Inspection   Period,   Purchaser
acknowledges  that Seller has afforded  Purchaser a full  opportunity to conduct
such  investigations  of the Property as Purchaser  deemed  necessary to satisfy
itself as to the condition of the Property and the existence or non-existence or
curative  action to be taken  with  respect  to any  Hazardous  Materials  on or
discharged  from the  Property,  and will rely solely upon same and not upon any
information  provided by or on behalf of Seller or its agents or employees  with
respect thereto,  other than such  representations,  warranties and covenants of
Seller as are expressly  set forth in this  Agreement.  Upon Closing,  Purchaser
shall  assume the risk that  adverse  matters,  including,  but not  limited to,
adverse  physical or construction  defects or adverse  environmental,  health or
safety  conditions,  may not have been revealed by Purchaser's  inspections  and
investigations.

Purchaser's Initials                    

         11.3 Seller Released from  Liability.  Purchaser  acknowledges  that it

hazardous,  undesirable  or  subject  to  regulation  and  that  may  need to be
specially  treated,  handled  and/or  removed from the Property under current or
future federal,  state and local laws,  regulations or  guidelines),  valuation,
salability  or utility  of the  Property,  or its  suitability  for any  purpose
whatsoever.  Purchaser  further  hereby WAIVES (and by closing this  transaction
will be deemed to have waived) any and all objections to or complaints regarding

actions),  or any private right of action under,  state and federal law to which
the Property is or may be subject,  including, but not limited to, CERCLA, RCRA,
physical characteristics and existing conditions, including, without limitation,
structural and geologic  conditions,  subsurface  soil and water  conditions and

environmental  conditions  on the Property  and the risk that  adverse  physical
characteristics and conditions,  including,  without limitation, the presence of
Hazardous  Materials or other  contaminants,  may not have been  revealed by its
investigation.

Price without the disclaimers and other agreements set forth above.

extent legally  possible,  effect shall be given to the intent manifested by the
portion  held  invalid or  inoperative.  The failure by either  party to enforce

agreement   between  the  parties  and  supersedes  all  prior   agreements  and

be  effective  until actual  receipt of such  notice.  Copies of notices are for
informational  purposes  only,  and a failure to give or  receive  copies of any
notice shall not be deemed a failure to give notice. Notices given by counsel to
the Purchaser shall be deemed given by Purchaser and notices given by counsel to

         12.10 Construction.  The parties acknowledge that the parties and their
counsel have reviewed and revised this  Agreement and agree that the normal rule
of construction - to the effect that any ambiguities are to be resolved  against
the drafting party shall not be employed in the interpretation of this Agreement

there shall be no recordation of either this Agreement or any memorandum hereof,
or any affidavit  pertaining  hereto, and any such recordation of this Agreement
or  memorandum or affidavit by Purchaser  without the prior  written  consent of
Seller shall constitute a default hereunder by Purchaser, whereupon Seller shall
have the remedies set forth in Section 10.1 hereof.

         12.14  Further  Assurances.  In addition to the acts and deeds  recited
herein and  contemplated to be performed,  executed  and/or  delivered by either
party at Closing, each party agrees to perform, execute and deliver, but without

part of Seller to be performed  pursuant to the  provisions  of this  Agreement,
except those which are herein specifically stated to survive Closing.

         12.16 ERISA.  Under no circumstances  shall Purchaser have the right to
assign this Agreement to any person or entity owned or controlled by an employee
benefit plan if Seller's sale of the Property to such person or entity would, in
the  reasonable  opinion of Seller's ERISA  advisors or  consultants,  create or
otherwise cause a "prohibited  transaction"  under ERISA. In the event Purchaser
assigns this  Agreement or transfers  any ownership  interest in Purchaser,  and
such  assignment  or transfer  would make the  consummation  of the  transaction
hereunder a "prohibited transaction" under ERISA and necessitate the termination
of this Agreement  then,  notwithstanding  any contrary  provision  which may be
contained herein, Seller shall have the right to terminate this Agreement.

         12.17 No Third Party Beneficiary.  The provisions of this Agreement and
of the documents to be executed and delivered at Closing are and will be for the
benefit of Seller,  Asset Manager and Purchaser only and are not for the benefit
of any third party (other than Asset Manager),  and accordingly,  no third party
(other than Asset  Manager)  shall have the right to enforce the  provisions  of
this  Agreement or of the  documents  to be executed  and  delivered at Closing,
except  that  a  tenant  of  the  Property  may  enforce  Purchaser's  indemnity
obligation under Section 4.11 hereof.

         12.18  Asset  Manager:  Designated  Representative.  Seller has engaged
Archon Group, L.P. or affiliated  companies ("Asset Manager") to provide certain
asset  management  services with respect to the Property,  including acting as a
liaison  between  Seller and Purchaser in connection  with the Property and this
Agreement.   The  Asset  Manager  will  appoint  one  or  more   representatives
("Designated  Representative(s)") to deal with Purchaser. Whenever any approval,
acceptance,  consent, direction or action of Seller is required pursuant to this
Agreement,  Purchaser  shall  send to the  Designated  Representative  a written
notice  requesting  same,  which notice shall: (i) describe in detail the matter
for which such  approval,  acceptance,  consent,  direction  or other  action of
Seller is requested; (ii) be accompanied by a copy of any contract, agreement or
other  document to be  executed by Seller  evidencing  such  approval,  consent,
acceptance,  direction  or action of Seller;  and (iii) be  accompanied  by such
other  documents,  written  explanations  and  information  as may be reasonably
necessary to explain the request  fully and  completely.  The Asset Manager will
communicate Seller's response to any such requests to Purchaser.

         12.19 Mandatory Arbitration.  The parties have agreed to submit certain
disputes to mandatory arbitration in accordance with the provisions of Exhibit G
attached hereto and made a part hereof for all purposes.

         12.20 Termination Reimbursement. Notwithstanding anything herein to the
contrary,  in all events where the Earnest Money is to be returned to Purchaser,
other than in case of (i)  Seller's  default and failure to close  hereunder  or
(ii)  failure of Seller to obtain  from  Seller's  Lender the release of the One
Acre Portion as  contemplated  by Section 6.4, or (iii)  failure of Seller to be
ready,  willing and able to deliver marketable title to the Property (subject to
the Permitted  Exceptions)  to Purchaser in accordance  with this  Agreement,  a
portion of the Earnest Money equal to the sum of all costs and expenses incurred
by Seller from and after  December 19, 1998 in connection  with the  prospective
development  of the  Property,  including  without  limitation  those  costs and
expenses  listed on Exhibit H  attached  hereto,  to the extent  said costs were
incurred on or after  December  19,  1998,  and  additional  costs and  expenses
incurred subsequent to the date through which the actual costs listed on Exhibit
H  are  current  (collectively,  the  "Termination  Reimbursement"),   shall  be
delivered  to Seller as  reimbursement  to Seller,  Purchaser  having  agreed to
reimburse  Seller for all such costs  incurred from and after December 19, 1998,
regardless of whether  Purchaser closes on the transaction,  as consideration to
Seller  for  entering  into this  Agreement.  If the  amount of the  Termination
Reimbursement  exceeds the Earnest Money, then the entire Earnest Money shall be
delivered to Seller and Purchaser shall  immediately pay to Seller the remainder
of the Termination Reimbursement, which obligation shall survive the termination
of this Agreement.

         12.21.  Further  Assurances.  Notwithstanding  anything  hereto  to the
contrary,  Seller  agrees that if  Purchaser  reasonably  determines  that other
permits and  approvals  are  required  for the  development  of the  Property in
accordance  with  existing  permits and  approvals  and  otherwise  as currently
contemplated,  Seller will take no action  adverse to the interests of Purchaser
with respect to any such  proceeding  and will  cooperate  with Purchaser in all
reasonable respects in connection with any such proceeding, but Seller shall not
be obligated to incur any liability or material expense in connection therewith.
This Section 12.21 shall survive the Closing for a period of one (1) year.

         12.22.  W9/TIB.  It is  acknowledged  that W9/TIB  Real Estate  Limited
Partnership,  a Delaware  limited  partnership  ("W9/TIB"),  a related entity to
Seller,  is the  current  owner of the 5 Omni Way  Parcel (of which the One Acre
Portion is a part) and the 2 Omni Way  Building.  For purposes of Sections  6.4,
6.5, 6.6 and 12.23  hereof,  and with respect to any  expressed  covenant on the
part of Seller  that  pertains  to the 5 Omni Way  Parcel  and/or the 2 Omni Way
Building,  Seller agrees to cause W9/TIB to perform or to cooperate  with Seller
in permitting Seller to perform said covenants.  Without limiting the generality
of the foregoing,  and subject to the provisions of Section 6.4,  Seller intends
to have W9/TIB convey the One Acre Portion to Seller prior to Closing.

         12.23 Telecommunication Easement. Seller agrees that at any time within
twelve (12) months after the Closing (the "Telecommunications Easement Period"),
if requested by  Purchaser  in writing and subject to the  conditions  set forth
below,  Seller  shall grant a  non-exclusive  easement  (the  "Telecommuncations
Easement") for the installation of  telecommuncations  equipment over and across
the 5 Omni Way Parcel and  connecting  the 2 Omni Way Building to the  Property.
Additionally,  if at  the  time  the  Telecommunications  Easement  is  executed
Purchaser, as tenant, has entered into a binding,  written lease of the building
located at 4 Omni Way,  Chelmsford,  Massachusetts  (the "4 Omni Way Building"),
then at Purchaser's written request the  Telecommunications  Easement shall also
serve to connect the 4 Omni Way Building to the Property. The Telecommunications
Easement  shall survive only for so long as Purchaser  remains a tenant of the 2
Omni Way Building or the 4 Omni Way Building.  Seller and  Purchaser  agree that
the form of written instrument evidencing the Telecommunications  Easement shall
be in a form which is usual and customary for easements of this type (subject to
each party's reasonable approval and subject to the requirements of this Section
12.23) and further agree to negotiate in good faith in order to reach a mutually
acceptable form of  Telecommunications  Easement instrument.  Additionally,  the
location of the  Telecommunications  Easement across the 5 Omni Way Parcel shall
be as directed by Seller,  at Seller's  sole but  reasonable  discretion.  Final
approval of the  Telecommunications  Easement is and shall be conditioned on the
current tenant of the 5 Omni Way Parcel,  Sun Microsystems,  and Seller's Lender
each consenting in writing to the Telecommunications  Easement. Seller shall use
reasonable efforts to cause Sun Microsystems and Seller's Lender each to consent
in writing to the  Telecommunications  Easement as soon as  reasonably  possible
after  Seller  and  Purchaser  have  agreed  on the  form  and  location  of the
Telecommunications  Easement,  but Seller  shall not be  obligated  to incur any
material  cost  or  expense  whatsoever  in  connection  therewith.   All  costs
associated  with the  installation of any  telecommunications  equipment and the
perpetual maintenance thereof shall be borne solely by Purchaser,  and Purchaser
shall  indemnify   Seller  from  and  against  any  and  all  claims,   demands,
liabilities, causes of action, suits, judgments, damages and expenses (including
attorneys'   fees)   arising   from  the   Telecommunications   Easement.   Only
telecommunications  equipment  that is normal and customary  for  communications
between  buildings such as the office  building  contemplated to be built on the
Land, the existing 2 Omni Way Building and the existing 4 Omni Way Building, and
otherwise  acceptable to Seller,  in Seller's  reasonable  discretion,  shall be
permitted.  If for any reason the Closing does not occur or  Purchaser  does not
request the  Telecommunications  Easement in writing prior to the  expiration of
the  Telecommunications  Easement  Period,  or if  Purchaser  does  request  the
Telecommunications  Easement during the  Telecommunications  Easement Period but
thereafter  the condtions to Seller's  obligations  under this Section 12.23 are
not satisfied, then Seller's obligation to grant the Telecommunications Easement
shall forever terminate and be of no further force or effect. The agreements set
forth in this Section 12.23 shall survive the Closing.

or less than  $50,000.00,  then SET A (as set forth  below) will  apply.  If the
amount in  controversy  is  greater  than  $50,000.00  and less than or equal to
$250,000.00,  then SET B will apply.  The amount in  controversy  is  calculated
using the  amount of actual  damages  alleged  by the  Claiming  Party  (defined
below),  exclusive  of interest  and  attorneys'  fees.  The dispute  resolution
procedure  set  forth  below  does not  independently  give rise to any right or
remedy.  The procedure is intended to be applied to rights or remedies expressly
granted in other sections of this Agreement.

         Notice of  Dispute.  Any party  shall  give the other  parties  written
notice of the existence and nature of any dispute proposed to be arbitrated (the
"Written  Notice").  The Written  Notice must be served on the other  parties as
required  below.  The party serving  Written  Notice shall be referred to as the
"Claiming Party." The party to whom the claims are directed shall be referred to
as the "Responding Party."

         Appointment of Arbitrators.

                  SET  A:  The  parties  agree  that  these   disputes  will  be
arbitrated  by a single  arbitrator  who is a board  certified or licensed  real
estate attorney in the state in which the Property is located. The parties shall
attempt to agree upon an  arbitrator  within ten (10) days of the service of the
Written Notice. If the parties are unable to agree, then the arbitrator shall be
appointed  from,  and pursuant to the rules for commercial  arbitration  of, the
American  Arbitration  Association.  Prior to appointment,  the arbitrator shall
agree to conduct such  arbitration in strict  accordance  with the terms of this
Agreement.

                  SET  B:  The  parties  agree  that  these   disputes  will  be
arbitrated  by a panel of three (3)  arbitrators.  Each party shall  appoint one
person to serve as an  arbitrator  within  fifteen  (15) days of  receipt of the
Written Notice.  The two (2)  arbitrators  thus appointed shall within seven (7)
days of their appointment together select a third arbitrator with such knowledge
and  expertise  as  necessary  to serve as chairman of the panel of  arbitrators
(preferably a board  certified or licensed real estate  attorney in the state in
which the  Property is located),  and this person  shall serve as chairman.  The
three  arbitrators  shall  determine  all matters,  including  the panel's final
decision with respect to the claims  presented in the  arbitration,  by majority
vote.  If the two  arbitrators  selected by the parties are unable to agree upon
the  appointment  of the  third  arbitrator  within  seven  (7)  days  of  their
appointment,  both shall  give  written  notice of such  failure to agree to the
parties,  and if the  parties  fail to agree  upon the  selection  of such third
arbitrator  within  five (5) days  thereafter,  such third  arbitrator  shall be
appointed  from,  and pursuant to the rules for commercial  arbitration  of, the
American Arbitration  Association.  Prior to appointment,  each arbitrator shall
agree to conduct such  arbitration in strict  accordance  with the terms of this
Agreement.

         Initial  Meeting of the  Arbitrators.  Within  seven (7) days after the
selection  of the last  arbitrator  (SET A:  the  arbitrator;  SET B: the  third
arbitrator), the arbitrator(s) shall conduct an initial meeting with the parties
(the "Initial  Meeting").  All meetings between the arbitrators,  or between the
arbitrator(s) and the parties,  including the Initial Meeting,  may be conducted
by telephone, with the exception of the arbitration hearing at which evidence is
presented. At the Initial Meeting, the parties and the arbitrator(s) shall agree
upon a schedule for the  arbitration  proceedings,  with dates no later than the
deadlines  provided below. The statement of claim, the response to the statement
of claim and  counterclaims  (if any), and the response to the counterclaims (if
any)  (collectively,  the "Pleadings")  shall be submitted to each arbitrator on
the date they are served,  unless  service  occurs prior to  appointment  of all
arbitrators.  If service of any of the Pleadings occurs prior to the appointment
of any of the  arbitrators,  copies of any such Pleadings  shall be submitted to
such arbitrator promptly after such arbitrator's appointment.

         Conduct of the Arbitration.

                  SET A: With respect to each dispute to be arbitrated,  no more
than six (6) months shall pass between the selection of the  arbitrator  and the
release  of a  decision  by the  arbitrator;  no more  than two (2)  depositions
(lasting  in total for both  depositions  no more than 15 hours) may be taken by
each of the Claiming  Party or the Responding  Party,  and no more than ten (10)
interrogatories may be asked for by each of the Claiming Party or the Responding
Party.  The  arbitration  hearing  shall last no more than two (2) days with the
time divided equally between the parties. All proceedings,  including discovery,
depositions, and the arbitration hearings shall be governed by the Federal Rules
of Civil  Procedure and the Local Rules of Civil  Procedure of the United States
District  Court for the district in which the  Property is located,  unless such
rules  conflict  with  the  provisions  of this  Agreement,  in  which  case the
provisions of this Agreement control; provided,  however, that the parties agree
that the provisions of Federal Rule of Civil Procedure 26(a) shall not apply.

                  SET B: With respect to each dispute to be arbitrated,  no more
than eleven (11) months shall pass between the selection of the third arbitrator
and the release of a decision by the  arbitration  panel; no more than eight (8)
depositions  (lasting in total for all eight  depositions no more than 50 hours)
may be taken by each of the Claiming Party or the Responding  Party, and no more
than thirty (30)  interrogatories may be asked for by each of the Claiming Party
or the Responding  Party.  The arbitration  hearing shall last no more than five
(5) days with the time divided  equally  between the parties.  All  proceedings,
including discovery, depositions, and the arbitration hearings shall be governed
by the Federal Rules of Civil  Procedure and the Local Rules of Civil  Procedure
of the United  States  District  Court for the district in which the Property is
located,  unless such rules conflict with the provisions of this  Agreement,  in
which case the provisions of this Agreement control; provided, however, that the
parties agree that the provisions of Federal Rule of Civil Procedure 26(a) shall
not apply.

         Motions.   The   parties  may  make   applications   to  the  panel  of
arbitrator(s) regarding issues of discovery,  procedure and privilege.  Any such
motions  shall  be  made  to  and  resolved  by the  arbitrator(s)  as  soon  as
practicable.  No party shall be permitted  to file any motions for  dismissal of
claims (including dismissal based upon failure to join an indispensable  party),
or for summary judgment,  concerning the claims or counterclaims asserted in any
arbitration.
