             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)


1.    BASIS OF PRESENTATION

      The unaudited consolidated financial statements of Brooks Automation, Inc.
      and its subsidiaries (the "Company") included herein have been prepared in
      accordance with generally accepted accounting principles. In the opinion
      of management, all material adjustments necessary for a fair presentation
      of the results for the periods presented have been reflected.

      The accompanying financial information should be read in conjunction with
      the consolidated financial statements and notes thereto contained in the
      Company's Annual Report on Form 10-K, filed with the United States
      Securities and Exchange Commission for the year ended September 30, 1999.

      The Company made several acquisitions during fiscal year 1999 which were
      accounted for using the purchase method of accounting: the Infab Division
      ("Infab") of Jenoptik AG on September 30, 1999; Domain Manufacturing
      Corporation ("Domain") on June 30, 1999 and Hanyon Technology, Inc.
      ("Hanyon") on April 2, 1999. Accordingly, the Company's Consolidated
      Statements of Operations and of Cash Flows for the three months ended
      December 31, 1999 include the results of these acquired entities.

      In June 1999, the Company formed a joint venture in Korea with Samsung
      Electronics ("Samsung"). This joint venture is 70% owned by the Company
      and 30% owned by Samsung. The Company consolidates fully the financial
      position and results of operations of the joint venture and accounts for
      the minority interest in the consolidated financial statements.

      The consolidated financial statements for the three months ended December
      31, 1998 have been restated to reflect the acquisition of Smart Machines
      Inc. ("Smart Machines") in a pooling of interests transaction effective
      August 31, 1999.

      In December 1998, the American Institute of Certified Public Accountants
      issued Statement of Position ("SOP") 98-9, "Modification of SOP 97-2,
      Software Revenue Recognition, With Respect to Certain Transactions", which
      addresses software revenue recognition as it applies to certain
      multiple-element arrangements. SOP 98-9 also amends SOP 98-4, "Deferral of
      the Effective Date of a Provision of SOP 97-2", to extend the deferral of
      certain passages of SOP 97-2 through fiscal years beginning on or before
      March 15, 1999. Accordingly, provisions of SOP 98-9 are effective for the
      Company's fiscal year 2000. Implementation of the provisions of this SOP
      has not had a material effect on revenues or earnings.

2.    BUSINESS ACQUISITIONS

      In connection with the acquisitions of Infab, Domain and Hanyon, the
      following pro forma results of operations have been prepared as though the
      acquisitions had occurred as of the beginning of the period presented.
      This pro forma financial information does not purport to be indicative of
      the results of operations

5.    SEGMENT, GEOGRAPHIC, SIGNIFICANT CUSTOMERS AND RELATED PARTY INFORMATION

      The Company has two reportable segments: tool automation and factory
      automation. The tool automation segment provides a full complement of
      semiconductor wafer and flat panel display substrate handling systems.
      Tool automation product revenues are comprised of factory hardware and
      tool control software products. Tool automation services revenue is
      comprised of spare parts sales and tool control application consulting
      services. The factory automation segment provides software products for
      the semiconductor manufacturing execution system ("MES") market. Factory
      automation product revenues include factory software and factory interface
      hardware products. Factory automation services revenue primarily consists
      of revenues related to consulting and software customization.

      The Company evaluates performance and allocates resources based on
      revenues and operating income. Operating income for each segment includes
      selling, general and administrative expenses directly attributable to the
      segment. Amortization of acquired intangible assets is excluded from the
      segments' operating income. The Company's non-allocable overhead costs,
      which include corporate general and administrative expenses, are allocated
      between the segments based upon segment revenues.

      Financial information for the Company's business segments is as follows

9.    CONTINGENCIES

      There has been substantial litigation regarding patent and other
      intellectual property rights in the semiconductor and related industries.
      The Company has received notice from a third party alleging infringements
      of such party's patent rights by certain of the Company's products. The
      Company's patent counsel is investigating the claim and the Company
      believes the patents claimed may be invalid. In the event of litigation
      with respect to this claim, the Company is prepared to vigorously defend
      its position. However, because patent litigation can be extremely
      expensive and time consuming, the Company may seek to obtain a license to
      one or more of the disputed patents. Based upon currently available
      information, the Company would only do so if such license fees would not
      be material to the Company's consolidated financial statements. Currently,
      the Company does not believe it is probable that the future events related
      to this threatened matter would have an adverse effect on the Company's
      business.

10.   SUBSEQUENT EVENTS

      On January 7, 2000, the Company entered into an agreement for an unsecured
      revolving credit facility for borrowings and letters of credit of up to
      $30.0 million. The credit facility will terminate at the end of two years.
      The interest rates for borrowings and letters of credit under the facility
      are expressed in relation to LIBOR and a margin of 1.75% to 2.25%, or from
      0.25% to 0.75% above a base rate. The Company expects to use the
      borrowings and letters of credit for working capital and general purposes,
      including financing potential acquisitions.

      On January 6, 2000, the Company completed the acquisition of the
      businesses of Auto-Soft Corporation ("ASC") and AutoSimulations, Inc.
      ("ASI") from Daifuku America Corporation ("Daifuku America"), a U.S.
      subsidiary of Daifuku Co., Ltd. of Japan. ASC is a leading material
      handling software and systems integration company focusing on
      manufacturing and distribution of logistic systems for the semiconductor
      industry. ASI is a world leader in robotic and material handling
      simulation, scheduling and real time dispatching software for the
      semiconductor industry. At closing, the Company paid $27.0 million in
      cash, 535,404 shares of Brooks common stock with a value of $14.7 million
      and a $16.0 million promissory note payable in one year.

      In February 2000, the Company entered into operating leases for
      manufacturing and office facilities through 2010. These leases contain
      renewal and sublease options. Future minimum annual lease payments are
      approximately $1.4 million to $3.0 million over the term of the leases.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

Certain statements in this quarterly report constitute "forward-looking
statements" which involve known risks, uncertainties and other factors which may
cause the actual results, performance or achievements of Brooks Automation, Inc.
("Brooks" or the "Company") to be materially different from any future results,
performance or achievements expressed or implied by such forward looking
statements. Such factors include the factors that may affect future results set
forth in Management's Discussion and Analysis of Financial Condition and Results
of Operations, which is included in this report. Precautionary statements made
herein should be read as being applicable to all related forward-looking
statements wherever they appear in this report.

OVERVIEW

The Company is a leading supplier of integrated tool and factory automation
solutions for the global semiconductor and related industries such as the data
storage and flat panel display manufacturing industries. The Company's product
revenues include sales of hardware and software products. The Company's service
revenues are primarily comprised of tool control application consulting
services, consulting, software customization and spare parts sales.

Many of the Company's customers purchase the Company's vacuum transfer robots
and other modules before purchasing the Company's vacuum central wafer handling
systems. The Company believes that once a customer has selected the Company's
products for a process tool, the customer is likely to rely on those products
for the life of that process tool model, which can be in excess of five years.
Conversely, losing a bid for a manufacturing execution system ("MES") does not
preclude the Company from securing optimization products to fit with a
competitor's MES.

A significant portion of the Company's revenues have been generated by sales to
customers in the United States, although the Company believes that a significant
portion of these customers incorporate the Company's products into equipment
sold to their foreign customers. The Company's foreign sales have occurred
principally in Japan, South Korea, Taiwan, Singapore and Europe.

The Company's foreign revenues are generally denominated in United States
dollars. Accordingly, foreign currency fluctuations have not had a significant
impact on the comparison of the results of operations for the periods presented.
The costs and expenses of the Company's international subsidiaries are generally
denominated in currencies other than the United States dollar. However, since
the functional currency of the Company's international subsidiaries is the local
currency, foreign currency translation adjustments are reflected as a component
of stockholders' equity under the caption "Accumulated other comprehensive
income (loss)". To the extent that the Company expands its international
operations or changes its pricing practices to denominate prices in foreign
currencies, the Company will be exposed to increased risk of currency
fluctuation.

The Company's business is highly dependent upon the capital expenditures of
semiconductor and flat panel display manufacturers which historically have been
cyclical, and the Company's ability to develop, manufacture and sell new
products and product enhancements. The Company's results will also be affected,
especially when measured on a quarterly basis, by the volume, composition and
timing of orders, conditions in industries served by the Company, competition
and general economic conditions.

BASIS OF PRESENTATION

The Company made several acquisitions during fiscal year 1999 which were
accounted for using the purchase method of accounting: the Infab Division
("Infab") of Jenoptik AG on September 30, 1999; Domain Manufacturing Corporation
("Domain") on June 30, 1999 and Hanyon Technology, Inc. ("Hanyon") on April 2,
1999. Accordingly, the Company's Consolidated Statements of Operations and of
Cash Flows for the three months ended December 31, 1999 include the results of
these acquired entities.

In June 1999, the Company formed a joint venture in Korea with Samsung
Electronics ("Samsung"). This joint venture is 70% owned by the Company and 30%
owned by Samsung. The Company consolidates fully the financial position and
results of operations of the joint venture and accounts for the minority
interest in the financial statements.

The financial statements for the three months ended December 31, 1998 have been
restated to reflect the acquisition of Smart Machines Inc. ("Smart Machines") in
a pooling of interests transaction effective August 31, 1999.

RECENT DEVELOPMENTS

On January 6, 2000, the Company completed the acquisition of the businesses of
Auto-Soft Corporation ("ASC") and AutoSimulations, Inc. ("ASI") from Daifuku
America Corporation ("Daifuku America"), a U.S. subsidiary of Daifuku Co., Ltd.
of Japan. ASC is a leading material handling software and systems integration
company focusing on manufacturing and distribution of logistic systems for the
semiconductor industry. ASI is a world leader in robotic and material handling
simulation, scheduling and real time dispatching software for the semiconductor
industry. The Company acquired ASC and ASI for $27.0 million in cash, 535,404
shares of Brooks common stock with a value of $14.7 million and a $16.0 million
promissory note payable in one year.

RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 1999, COMPARED TO THREE MONTHS ENDED DECEMBER
31, 1998

For the three months ended December 31, 1999, the Company reported net income of
$2.9 million, compared to a net loss of $1.5 million in the same prior year
period. Net income before amortization of acquired intangible assets, net of
taxes, was $3.3 million in the three months ended December 31, 1999. There was
no amortization of acquired intangible assets for the three months ended
December 31, 1998.

                      AND RESULTS OF OPERATIONS - Continued


REVENUES

The Company reported revenues of $50.3 million in the three months ended
December 31, 1999, compared to $20.1 million in the same prior year period.
Product revenues increased $27.7 million, or 179.7%. This growth is primarily
attributable to the overall strength in the original equipment manufacturer
("OEM") markets, software business growth and acquisitions. Services revenues
increased $2.5 million, or 54.9%, primarily as a result of the Company's
acquisitions and the impact of those acquisitions on consulting services
associated with factory automation.

Foreign revenues were $26.2 million, or 52.1% of revenues, and $12.0 million, or
59.9% of revenues, in the three-month periods ended December 31, 1999 and 1998,
respectively. The Company expects that foreign revenues will continue to account
for a significant portion of total revenues.

GROSS PROFIT

Gross profit increased to 48.6% for the three months ended December 31, 1999,
compared to 42.7% for the same prior year period.

Gross profit on product revenues increased to 48.5% for the three months ended
December 31, 1999, from 41.6% in the comparable prior year period. The increase
is primarily attributable to improvements in manufacturing capacity utilization
and the acquisition of higher margin software product businesses, partially
offset by the Infab operations' historically lower margin structure. In future
periods, gross profit may be adversely affected by changes in product mix or
continued price competition.

Gross profit on service revenues was 49.3% for the three months ended December
31, 1999, an increase from 46.3% in the three months ended December 31, 1998.
The increase is primarily attributable to improved market conditions and change
in services mix. Included in the cost of services revenues are global support
customer costs, consisting primarily of personnel costs and travel expenses.

RESEARCH AND DEVELOPMENT

Research and development expenses increased by 44.8%, to $7.1 million in the
three months ended December 31, 1999, from $4.9 million in the comparable prior
year period. However, research and development expenses decreased as a
percentage of revenues, to 14.2% in the three months ended December 31, 1999,
from 24.6% in the same prior year period. The increase in absolute spending is
the result of the research and development efforts related to the Company's
recent acquisitions as well as incremental spending associated with the launch
of new atmospheric products and the transition to next generation vacuum wafer
handling products, partially offset by the elimination of redundant research and
development programs. The Company will continue to invest in research and
development to enhance existing and develop new tool and factory hardware and
software automation solutions for the semiconductor, data storage and flat panel
display manufacturing industries.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses increased by 106.9%, to $12.5
million, in the three months ended December 31, 1999, compared to $6.0 million
in the same prior year period. However, selling, general and administrative
expenses decreased as a percentage of revenues, to 24.9%, in the three months
ended December 31, 1999, from 30.1% in the comparable prior year period. The
increase in absolute spending is the result of expanded sales and marketing
activities as well as general and administration support costs associated with
the Company's recently completed acquisitions and infrastructure improvements,
while the improvement of these costs as a percentage of revenues reflects the
Company's efforts at expanding its product offerings and customer base.

AMORTIZATION OF ACQUIRED INTANGIBLE ASSETS

Amortization expense for acquired intangible assets totaled $0.8 million in the
three months ended December 31, 1999, and is related to acquired intangible
assets of the Infab, Domain and Hanyon acquisitions, all of which occurred
during the second half of fiscal 1999. There was no amortization expense for the
three months ended December 31, 1998.

INTEREST INCOME AND EXPENSE

Interest income decreased by 16.6%, to $0.6 million, in the three months ended
December 31, 1999, compared to $0.8 million in the same period of the prior
year, due primarily to lower cash and investment asset balances. Interest
expense decreased by 49.3%, to $38,000, in the three months ended December 31,
1999, from $75,000 in the comparable prior year period.

INCOME TAX PROVISION (BENEFIT)

The Company recorded net income tax expense of $1.8 million and net tax benefits
of $0.2 million in the three months ended December 31, 1999 and 1998,
respectively. The tax provision is attributable to federal, state, foreign and
withholding taxes. Federal and state taxes have been reduced for net operating
losses, research and development tax credits and a foreign sales corporation
benefit.

                      AND RESULTS OF OPERATIONS - Continued


LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $61.1 million at December 31, 1999, a decrease of
$5.3 million from September 30, 1999. In connection with its acquisition of ASC
and ASI on January 6, 2000, the Company paid Daifuku America $27.0 million in
cash and issued Daifuku America a note in the amount of $16.0 million, which is
due on January 6, 2001.

Cash used in operations was $1.7 million, and is primarily attributable to an
increase in accounts receivable of $10.8 million, partially offset by
depreciation and amortization of $2.6 million, and increases of $1.7 million and
$2.0 million in accounts payable and accrued expenses and other current
liabilities, respectively.

Cash used in investing activities was $3.5 million, and was principally
comprised of $3.3 million used for capital additions, primarily in
telecommunications, systems infrastructure and for computer requirements. Cash
provided by financing activities was $31,000, comprised of $155,000 of proceeds
from the issuance of common stock, net of issuance costs, partially offset
by $124,000 for payments of long-term debt.

While the Company has no significant capital commitments, as the Company expands
its product offerings and prepares for expected growth, the Company anticipates
that it will continue to make capital expenditures to support its business. The
Company is also planning to expand its capacity in its new Chelmsford facility
and acquire capital equipment and management information systems. The Company
may also use its resources to acquire companies, technologies or products that
complement the business of the Company.

The Company has an unsecured revolving credit facility for borrowings and
letters of credit of up to $30.0 million. The credit facility will terminate in
January 2002. The interest rates for borrowings and letters of credit under the
facility are expressed in relation to LIBOR and a margin of 1.75% to 2.25%, or
from 0.25% to 0.75% above a base rate. In connection with the lease for its new
Chelmsford facility, the Company issued its landlord a letter of credit in the
amount of $1.0 million to secure the Company's obligations under the lease. This
reduced the amount available to the Company under the credit facility to $29.0
million. Under the terms of the credit facility, the Company is required to
comply with various covenants, including the maintenance of specified financial
ratios, as defined, and limits on the Company's annual level of capital
expenditures. At January 31, 2000, the Company was in compliance with these
covenants.

The Company believes that anticipated cash from operations, available funds and
borrowings available under the Company's bank lines of credit and the proceeds
from the proposed sale of common stock described below, will be adequate to fund
the Company's currently planned working capital and capital expenditure
requirements for at least the next twelve months. The sufficiency of the
Company's resources to fund its needs for capital is subject to known and
unknown risks, uncertainties and other factors which may have a material adverse
effect on the Company's business, including, without limitation, the factors
discussed under "Factors That May Affect Future Results."

The Company has filed a registration statement for a public offering of
3,250,000 shares of the Company's common stock. The Company is proposing to sell
2,750,000 of these shares and selling stockholders are proposing to sell 500,000
shares. The Company will not receive any of the proceeds from the shares sold by
the selling stockholders. The Company plans to apply any proceeds of the
offering, net of expenses, for working capital and general corporate purposes.
The Company cannot guarantee that it will complete the offering on favorable
terms, if at all.

YEAR 2000 READINESS DISCLOSURE

The year 2000 issue is the potential for system and processing failure of
date-related data as the result of computer-controlled systems using two digits
rather than four digits to define the applicable year. For example, computer
programs that have time-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in system failure or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities. Problems associated with the year 2000
may not become apparent until some time after January 2000.

           Internal infrastructure compliance. Brooks may be affected by year
2000 issues related to non-compliant information technology systems and other
systems operated or sold by Brooks or by third parties. Brooks has substantially
completed assessment of its internal information technology systems and
applications and believes that all critical applications are year 2000
compliant. Brooks also has evaluated its information technology hardware and its
non-information technology systems, including facilities and other operations,
such as financial, security and utility systems. As of the end of calendar year
1999, Brooks had completed the remediation of all items identified as
non-compliant.

           Product compliance. Brooks has completed a Year 2000 readiness
evaluation of its current generation of released products and believes that
products distributed after December 31, 1998 are Year 2000 compliant. Brooks
cannot guarantee that product testing has identified all Year 2000 related
issues that could have an adverse affect on Brooks' financial condition and
results of operations.

           Acquisitions. Brooks has acquired seven businesses since September
1998: Auto-Soft Corporation, AutoSimulations, Inc., Infab, Smart Machines,
FASTech, Hanyon and Domain. Brooks is in various stages of negotiation with
respect to the acquisition of several additional businesses. As part of Brooks'
due diligence examination of completing acquisitions, Brooks conducted a limited
evaluation of their year 2000 readiness. Brooks believes there are no
significant year 2000 related issues arising from the companies that Brooks has
acquired. Brooks cannot guarantee that it has identified and properly evaluated
year 2000 issues relating to the acquired companies. Brooks also can give no
assurance that it will properly identify year 2000 issues relating to any
companies acquired in the future.

           Third Party Compliance. Although Brooks believes that its systems are
year 2000 compliant, Brooks utilizes third party equipment and software that may
not be year 2000 compliant. In addition, Brooks' products and software are often
sold integrated into or interfaced with third party equipment or software.
Failure of third party equipment or software to operate properly with regard to
the year 2000 and thereafter could require Brooks to incur unanticipated
expenses to remedy any problems, which could have a material adverse effect on
Brooks' business, results of operations and financial condition. Brooks may also
be vulnerable to any failures by its major suppliers, service providers and
customers to remedy their own internal information technology and
non-information technology system year 2000 issues which could, among other
things, have a material adverse effect on Brooks supplies and orders. At this
time, Brooks is unable to estimate the nature or extent of any potential


<PAGE>   19


                             BROOKS AUTOMATION, INC.
           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS - Continued


adverse impact resulting from the failure of third parties, such as its
suppliers, service providers and customers, to achieve year 2000 compliance.
Moreover, such third parties, even if year 2000 compliant, could experience
difficulties resulting from year 2000 issues that may affect their suppliers,
service providers and customers. As a result, although Brooks does not currently
anticipate, based upon surveys, discussions and actual experience to date in
2000, that it will experience any material shipment delays from its major
product suppliers or any material sales delays from its major customers due to
year 2000 issues, there can be no assurance that these third parties will not
experience year 2000 problems or that any problems would have an adverse
material effect on Brooks' business, results of operations and financial
condition. Because the cost and timing of year 2000 compliance by third parties
such as suppliers, service providers and customers is not within Brooks'
control, Brooks cannot give any assurance with respect to the cost or timing of
such efforts or any potential adverse effects on Brooks of any failure by these
third parties to achieve year 2000 compliance.

           Brooks relies on commercial or government suppliers for services
related to Brooks' infrastructure, including utilities, transportation,
financial, governmental, communications and other services. These suppliers pose
an undetermined risk to Brooks' facilities and operations worldwide. In some
cases, alternate suppliers of these services, such as electrical utilities, are
unavailable, and failure by a supplier could adversely impact Brooks.

           Costs. Based on its investigation to date, Brooks does not expect the
total cost of its year 2000 assessment and planning to have a material adverse
effect on Brooks' business or financial results. On a cumulative basis, Brooks
has incurred approximately $800,000 in year 2000 compliance costs. Brooks does
not anticipate the need for additional significant expenditures.

           Contingency Plan. Brooks has developed contingency plans, as
appropriate, and believes its year 2000 compliance efforts to be materially
complete in the event year 2000 problems relating to its operations arise.

           Worst Case Scenario. To the extent that Brooks does not identify any
material non-compliant information technology systems or non-information
technology systems operated by Brooks or by third parties, such as Brooks'
suppliers, service providers and customers, the most reasonably likely worst
case year 2000 scenario is a systemic failure beyond the control of Brooks, such
as a prolonged telecommunications or electrical failure, or a general disruption
in United States or global business activities that could result in a
significant economic downturn. Brooks believes that the primary business risks,
in the event of such failure or other disruption, would include but not be
limited to, loss of customers or orders, increased operating costs, inability to
obtain inventory on a timely basis, disruptions in product shipments, or other
business interruptions of a material nature, as well as claims of mismanagement,
misrepresentation, or breach of contract, any of which could have a material
adverse effect on Brooks' business, results of operations and financial
condition.

RECENTLY ENACTED ACCOUNTING PRONOUNCEMENTS

In December 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-9, "Modification of SOP 97-2, Software Revenue
Recognition, With Respect to Certain Transactions", which addresses software
revenue recognition as it applies to certain multiple-element arrangements. SOP
98-9 also amends SOP 98-4, "Deferral of the Effective Date of a Provision of SOP
97-2", to extend the deferral of certain passages of SOP 97-2 through fiscal
years beginning on or before March 15, 1999. Accordingly, provisions of SOP 98-9
are effective for the Company's fiscal year 2000. Implementation of the
provisions of this SOP has not had a material effect on revenues or earnings.


FACTORS THAT MAY AFFECT FUTURE RESULTS


     You should carefully consider the risks described below and the other
information in this report before deciding to invest in shares of our common
stock. While these are the risks and uncertainties we believe are most important
for you to consider, you should know that they are not the only risks or
uncertainties facing us or which may adversely affect our business. If any of
the following risks or uncertainties actually occur, our business, financial
condition and operating results would likely suffer. In that event, the market
price of our common stock could decline and you could lose all or part of the
money you paid to buy our common stock.

                        RISKS RELATING TO OUR OPERATIONS

     The Cyclical Demand of Semiconductor Manufacturers Affects our Operating
Results.  Our business is significantly dependent on capital expenditures by
semiconductor manufacturers. The level of semiconductor manufacturers' capital
expenditures is dependent on the current and anticipated market demand for
semiconductors. Demand for semiconductors is cyclical and has historically
experienced periodic downturns. During these downturns, our revenues have
dropped and we have incurred losses. We believe that downturns in the
semiconductor manufacturing industry will occur in the future and will result in
decreased demand for our products. Despite the addition of our factory
automation business in fiscal 1999, our financial results will continue to be
dependent on capital expenditures by semiconductor manufacturers. Downturns in
the semiconductor business, when fewer new facilities are being built, could
harm our financial results as have downturns in the past.

     Our Sales Volume Depends on the Sales Volume of our Original Equipment
Manufacturer Customers. We sell a majority of our tool automation products to
original equipment manufacturers who incorporate our products into their
equipment. Therefore, our revenues are directly dependent on the ability of
these customers to develop and market their equipment in a timely,
cost-effective manner.

     We Rely on a Small Number of Customers for a Large Portion of our
Revenues.  We receive a significant portion of our revenues in each fiscal
period from a limited number of customers. The loss of one or more of these
major customers, or a decrease in orders by one or more customers, would
adversely affect our business. Sales to our ten largest customers accounted for
56% of total revenues in the three months ended December 31, 1999 and 63% of
total revenues in fiscal 1999. Sales to Lam Research Corporation, our largest
customer, accounted for approximately 14% of total revenues in the three months
ended December 31, 1999 and 15% of our total revenues in 1999.

     Delays in Shipment of a few of our Large Orders Could Substantially
Decrease our Revenues. Historically, a substantial portion of our quarterly and
annual revenues came from sales of a small number of large orders. These orders
consist of products with high selling prices compared to our other products. As
a result, the timing of the recognition of revenue from one of these large
orders can have a significant impact on our total revenues and operating results
for a particular period. Our operating results could be harmed if orders for
even a small number of large orders are canceled or rescheduled by customers or
cannot be filled due to delays in manufacturing, testing, shipping or product
acceptance.

     We Have Significant Fixed Costs which are not Easily Reduced if Revenues
Fall Below Expectations. Our expense levels are based in part on our future
revenue expectations. Many of our expenses, particularly those relating to
capital equipment and manufacturing overhead, are relatively fixed. If we do not
meet our sales goals we may be unable to rapidly reduce these fixed costs. Our
ability to reduce expenses is further constrained because we must continue to
invest in research and development to maintain our competitive position and to
maintain service and support for our existing global customer base. Accordingly,
if we suffer an unexpected downturn in revenue, our inability to reduce fixed
costs rapidly could increase the adverse impact on our results of operations.

     Our Lengthy Sales Cycle Requires us to Incur Significant Expenses with No
Assurance that we Will Generate Revenue.  Our tool automation products are
generally incorporated into original equipment manufacturer equipment at the
design stage. To obtain new business from our original equipment

<PAGE>   21

manufacturer customers, we must develop products for selection by a potential
customer at the design stage. This often requires us to make significant
expenditures without any assurance of success. The original equipment
manufacturer's design decisions often precede the generation of volume sales, if
any, by a year or more. We also must complete successfully a lengthy evaluation
period before we can achieve volume sales of our manufacturing execution system
software and process optimization software to our factory automation customers.
We cannot guarantee that we will continue to achieve design wins or satisfy
evaluations by our factory automation customers of our software. We cannot
guarantee that the equipment manufactured by our original equipment
manufacturing customers will be commercially successful. If we or our original
equipment manufacturing customers fail to develop and introduce new products
successfully and in a timely manner, our business and financial results will
suffer.

     Our International Business Operations Expose us to a Number of Difficulties
in Coordinating our Activities Abroad and in Dealing with Multiple Regulatory
Environments.  Approximately 52% of our total revenues in the three months
ended December 31, 1999 and 41% of our total revenues in fiscal 1999 were
derived from customers located outside North America. We anticipate that
international sales will continue to account for a significant portion of our
revenues. Our vendors are located in several different foreign countries. As a
result of our international business operations, we are subject to various
risks, including:

     - difficulties in staffing and managing operations in multiple locations in
       many countries;

     - challenges presented by collecting trade accounts receivable in foreign
       jurisdictions;

     - possible adverse tax consequences;

     - governmental currency controls;

     - changes in various regulatory requirements;

     - political and economic changes and disruptions; and

     - export/import controls and tariff regulations.

     To support our international customers, we maintain locations in several
countries, including Japan, South Korea, Germany, United Kingdom, Malaysia,
Taiwan, Singapore and Canada. We cannot guarantee that we will be able to manage
these operations effectively. We cannot assure you that our investment in these
international operations will enable us to compete successfully in international
markets or to meet the service and support needs of our customers, some of whom
are located in countries where we have no infrastructure.

     Although our international sales are primarily denominated in U.S. dollars,
changes in currency exchange rates can make it more difficult for us to compete
with foreign manufacturers on price. If our international sales increase
relative to our total revenues, these factors could have a more pronounced
effect on our operating results.

     We Must Continually Improve our Technology to Remain Competitive.
Technology changes rapidly in the semiconductor, data storage and flat panel
display manufacturing industries. We believe our success will depend upon our
ability to enhance our existing products and to develop and market new products
to meet customer needs. We cannot guarantee that we will identify and adjust to
changing market conditions or succeed in introducing commercially rewarding
products or product enhancements. The success of our product development and
introduction depends on a number of factors, including:

     - accurately identifying and defining new products;

     - completing and introducing new product designs in a timely manner;

     - market acceptance of our products and our customers' products; and

     - determining a comprehensive, integrated product strategy.


<PAGE>   22

     We Face Significant Competition Which Could Result in Decreased Demand for
Our Products or Services.  The markets for our products are intensely
competitive and we may not be able to compete successfully. We believe that our
primary competition in the tool automation market is from integrated original
equipment manufacturers that satisfy their semiconductor and flat panel display
handling needs themselves rather than by purchasing systems or modules from an
independent supplier like us. Many of these original equipment manufacturers
have substantially greater resources than we do. Applied Materials, Inc., the
leading process equipment original equipment manufacturer, develops and
manufactures its own central wafer handling systems and modules. We may not be
successful in selling our products to original equipment manufacturers that
currently satisfy their wafer or substrate handling needs themselves, regardless
of the performance or the price of our products. Moreover, integrated original
equipment manufacturers may begin to commercialize their handling capabilities
and become our competitors.

     We believe that the primary competitive factors in the end-user
semiconductor manufacturer market for factory automation software and process
control software are product functionality, price/performance, ease of use,
hardware and software platform compatibility, vendor reputation and financial
stability. The relative importance of these competitive factors may change over
time. We directly compete in this market with various competitors, including
Applied Materials-Consilium, PRI-Promis, IBM-Poseidon and numerous small,
independent software companies. We also compete with the in-house software
staffs of semiconductor manufacturers like NEC. Most of those manufacturers have
substantially greater resources than us.

     We believe that the primary competitive factors in the factory interface
market are technical and technological capabilities, reliability,
price/performance, ease of integration and global sales and support capability.
In this market, we compete directly with Asyst, Fortrend, Kensington and Rorze.
Some of these competitors have substantial financial resources and extensive
engineering, manufacturing and marketing capabilities.

     We believe our sale of products for the flat panel display process
equipment market is heavily dependent upon our penetration of the Japanese
market. In addressing the Japanese markets, we may be at a competitive
disadvantage to Japanese suppliers that, historically, have been the supplier of
choice to these markets.

     Much of our Success and Value Lies in our Ownership and Use of Intellectual
Property and our Failure to Protect That Property Could Adversely Affect our
Future Growth.  Our ability to compete is heavily affected by our ability to
protect our intellectual property. We rely primarily on trade secret laws,
confidentiality procedures, patents, copyrights, trademarks and licensing
arrangements to protect our intellectual property. The steps we have taken to
protect our technology may be inadequate. Existing trade secret, trademark and
copyright laws offer only limited protection. Our patents could be invalidated
or circumvented. The laws of certain foreign countries in which our products are
or may be developed, manufactured or sold may not fully protect our products or
intellectual property rights. This may make the possibility of piracy of our
technology and products more likely. We cannot guarantee that the steps we have
taken to protect our intellectual property will be adequate to prevent
misappropriation of our technology. There has been substantial litigation
regarding patent and other intellectual property rights in semiconductor-related
industries. We may engage in litigation to:

     - enforce our patents;

     - protect our trade secrets or know-how;

     - defend ourselves against claims we infringe the rights of others; or

     - determine the scope and validity of the patents or intellectual property
       rights of others.

     Any litigation could result in substantial cost to us and divert the
attention of our management, which could harm our operating results.

     Our Operations Could Infringe on the Intellectual Property Rights of
Others.  Particular aspects of our technology could be found to infringe on the
intellectual property rights or patents of others. Other


<PAGE>   23

companies may hold or obtain patents on inventions or may otherwise claim
proprietary rights to technology necessary to our business. We cannot predict
the extent to which we may be required to seek licenses or alter our products so
that they no longer infringe the rights of others. We cannot guarantee that the
terms of any licenses we may be required to seek will be reasonable. Similarly,
changing our products or processes to avoid infringing the rights of others may
be costly or impractical or could detract from the value of our products.

     Our Business May be Harmed by Infringement Claims of General Signal or
Applied Materials.  We received notice from General Signal Corporation alleging
infringements of its patent rights by certain of our products. The notification
advised us that General Signal was attempting to enforce its rights to those
patents in litigation against Applied Materials, and that, at the conclusion of
that litigation, General Signal intended to enforce its rights against us and
others. According to a press release issued by Applied Materials in November
1997, Applied Materials settled its litigation with General Signal by acquiring
ownership of five General Signal patents. Although not verified by us, these
five patents would appear to be the patents referred to by General Signal in its
prior notice to us. Applied Materials has not contacted us regarding these
patents.

     We do not have Long-Term Contracts with our Customers and our Customers may
Cease Purchasing our Products at Any Time.  We generally do not have long-term
contracts with our customers. As a result, our agreements with our customers do
not provide any assurance of future sales. Accordingly:

     - our customers can cease purchasing our products at any time without
       penalty;

     - our customers are free to purchase products from our competitors;

     - we are exposed to competitive price pressure on each order; and

     - our customers are not required to make minimum purchases.

     Year 2000 Readiness; Year 2000 Problems Could Disrupt our Business.  The
year 2000 problem is the potential for system and processing failure of
date-related data as the result of computer-controlled systems using two digits
rather than four digits to define the applicable year. This could result in
system failure or miscalculations causing disruptions of operations, including,
among other things, temporary inability to process transactions, send invoices,
or engage in similar normal business activities. Problems associated with the
year 2000 may not become apparent until some time after January 2000.

     We have evaluated our internal software and products for year 2000
problems. We believe that our products and business will not be substantially
affected by the year 2000 problem and that we have no significant exposure to
liabilities related to the year 2000 problem for the products that we have sold.
We have also communicated with others, including suppliers and customers whose
computer systems' functionality could directly impact our operations.

     Although we believe our planning efforts are adequate to address our year
2000 concerns, undetected year 2000 problems may cause us to experience negative
consequences or significant costs. We cannot be sure that our suppliers,
customers or businesses that we may acquire will not experience similar
consequences or costs. Such consequences or costs could adversely affect our
business.

                          RISKS RELATING TO OUR GROWTH

     Rapid Growth is Straining our Operations and Requiring us to Incur Costs to
Upgrade our Infrastructure.  During the last two quarters, we have experienced
extremely rapid growth in our operations, the number of our employees, our
product offerings and the geographic area of our operations. Our growth places a
significant strain on our management, operations and financial systems. Our
future operating results will be dependent in part on our ability to continue to
implement and improve our operating and financial controls and management
information systems. If we fail to manage our growth effectively, our financial
condition, results of operations and business could be materially adversely
affected.


<PAGE>   24

     Our Operating Results Would Be Harmed if One of our Key Suppliers Fails to
Deliver Components for Our Products.  We currently procure many of our
components on an as needed, purchase order basis. We do not carry significant
inventories or have any long-term supply contracts with our vendors. With the
recent increased demand for semiconductor manufacturing equipment, our suppliers
are facing significant challenges in providing components on a timely basis. Our
inability to obtain components in required quantities or of acceptable quality
could result in significant delays or reductions in product shipments. This
would materially and adversely affect our operating results.

     Our Business Could be Harmed if We Fail to Adequately Integrate the
Operations of Our Acquisitions.  Our management must devote substantial time and
resources to the integration of the operations of our acquired businesses with
our business and with each other. If we fail to accomplish this integration
efficiently, we may not realize the anticipated benefits of our acquisitions.
The process of integrating supply and distribution channels, research and
development initiatives, computer and accounting systems and other aspects of
the operation of our acquired businesses, presents a significant challenge to
our management. This is compounded by the challenge of simultaneously managing a
larger entity. We have completed a number of acquisitions in a short period of
time. These businesses have operations and personnel located in Asia, Europe and
the United States and present a number of additional difficulties of
integration, including:

     - difficulties in the assimilation of products and designs into integrated
       solutions;

     - difficulties in informing customers, suppliers and distributors of the
       effects of the acquisitions and integrating them into our overall
       operations;

     - difficulties integrating personnel with disparate business backgrounds
       and cultures;

     - difficulties in defining and executing a comprehensive product strategy;

     - difficulties in managing geographically remote units;

     - difficulties associated with managing the risks of entering markets or
       types of businesses in which we have limited or no direct experience; and

     - difficulties in minimizing the loss of key employees of the acquired
       businesses.

     If we delay integrating or fail to integrate an acquired business or
experience other unforeseen difficulties, the integration process may require a
disproportionate amount of our management's attention and financial and other
resources. Our failure to adequately address these difficulties could harm our
business and financial results.

     Our Business May be Harmed by Acquisitions We Complete in the Future.  We
plan to continue to pursue additional acquisitions of related businesses. Our
identification of suitable acquisition candidates involves risks inherent in
assessing the values, strengths, weaknesses, risks and profitability of
acquisition candidates, including the effects of the possible acquisition on our
business, diversion of our management's attention and risks associated with
unanticipated problems or latent liabilities. If we are successful in pursuing
future acquisitions, we will be required to expend significant funds, incur
additional debt or issue additional securities, which may negatively affect our
results of operations and be dilutive to our stockholders. If we spend
significant funds or incur additional debt, our ability to obtain financing for
working capital or other purposes could decline and we may be more vulnerable to
economic downturns and competitive pressures. We cannot guarantee that we will
be able to finance additional acquisitions or that we will realize any
anticipated benefits from acquisitions that we complete. Should we successfully
acquire another business, the process of integrating acquired operations into
our existing operations may result in unforeseen operating difficulties and may
require significant financial resources that would otherwise be available for
the ongoing development or expansion of our existing business.

     We May not be Able to Recruit and Retain Necessary Personnel Because of
Intense Competition for Highly Skilled Personnel.  We need to hire and retain
substantial numbers of employees with technical backgrounds for both our
hardware and software engineering and support staffs. The market for these


<PAGE>   25

employees is intensively competitive, and we have occasionally experienced
delays in hiring these personnel. Due to the cyclical nature of the demand for
our products, we have had to reduce our workforce and then rebuild our workforce
as our business has gone through downturns followed by upturns. We currently
need to hire a number of highly skilled employees, especially in manufacturing,
to meet customer demand. Due to the competitive nature of the labor markets in
which we operate, this type of employment cycle increases our risk of not being
able to retain and recruit key personnel. Our inability to recruit, retain and
train adequate numbers of qualified personnel on a timely basis could adversely
affect our ability to develop, manufacture, install and support our products.

                       RISKS RELATING TO OUR COMMON STOCK

     Our Operating Results Fluctuate Significantly, Which Could Negatively
Impact our Business and our Stock Price.  Our margins, revenues and other
operating results can fluctuate significantly from quarter to quarter depending
upon a variety of factors, including:

     - the level of demand for semiconductors in general;

     - cycles in the market for semiconductor manufacturing equipment and
       automation software;

     - the timing and size of orders from our customer base;

     - our ability to manufacture, test and deliver products in a timely and
       cost-effective manner;

     - our success in winning competitions for orders;

     - the timing of our new product announcements and releases and those of our
       competitors;

     - the mix of products sold by us;

     - competitive pricing pressures; and

     - the level of automation required in fab extensions, upgrades and new
       facilities.

We entered into the factory automation software business in fiscal 1999. We
believe a substantial portion of our revenues from this business will be
dependent on achieving project milestones. As a result, our revenue from this
business will be subject to fluctuations depending upon a number of factors,
including whether we can achieve project milestones on a timely basis, if at
all, as well as the timing and size of projects.

     The Volatility of our Stock Price Could Adversely Affect an Investment in
our Stock.  The market price of our common stock has fluctuated widely. For
example, between August 25, 1999 and August 31, 1999, the price of our common
stock dropped from approximately $25.13 to $21.75 per share. Between January 4,
2000 and January 27, 2000, the price of our common stock rose from approximately
$30.63 to $54.44 per share. Consequently, the current market price of our common
stock may not be indicative of future market prices, and we may not be able to
sustain or increase the value of an investment in our common stock. Factors
affecting our stock price may include:

     - variations in operating results from quarter to quarter;

     - changes in earnings estimates by analysts or our failure to meet
       analysts' expectations;

     - changes in the market price per share of our public company customers;

     - market conditions in the industry;

     - general economic conditions;

     - low trading volume of our common stock; and

     - the number of firms making a market in our common stock.


<PAGE>   26

     In addition, the stock market has recently experienced extreme price and
volume fluctuations. These fluctuations have particularly affected the market
prices of the securities of high technology companies like us. These market
fluctuations could adversely affect the market price of our common stock.

     Provisions of our Certificate of Incorporation, Bylaws and Contracts May
Discourage Takeover Offers and may Limit the Price Investors Would be Willing to
Pay for our Common Stock.  Our certificate of incorporation and bylaws contain
provisions that may make an acquisition of us more difficult and discourage
changes in our management. These provisions could limit the price that certain
investors might be willing to pay in the future for shares of our common stock.
In addition, we have adopted a rights plan. In many potential takeover
situations, rights issued under the plan become exercisable to purchase our
common stock at a price substantially discounted from the then applicable market
price of our common stock. Because of its possible dilutive effect to a
potential acquiror, the rights plan would generally discourage third parties
from proposing a merger with or initiating a tender offer for us that is not
approved by our board of directors. Accordingly, the rights plan could have an
adverse impact on our stockholders who might want to vote in favor of the merger
or participate in the tender offer. In addition, shares of our preferred stock
may be issued upon terms the board of directors deems appropriate without
stockholder approval. Our ability to issue preferred stock in such a manner
could enable our board of directors to prevent changes in our management or
control.

                             BROOKS AUTOMATION, INC.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK


INTEREST RATE EXPOSURE

Based on Brooks' overall interest exposure at December 31, 1999, including all
interest rate-sensitive instruments, a near-term change in interest rates within
a 95% confidence level based on historical interest rate movements would not
materially affect the consolidated results of operations or financial position.

CURRENCY RATE EXPOSURE

Brooks' foreign revenues are generally denominated in United States dollars.
Accordingly, foreign currency fluctuations have not had a significant impact on
the comparison of the results of operations for the periods presented. The costs
and expenses of Brooks' international subsidiaries are generally denominated in
currencies other than the United States dollar. However, since the functional
currency of Brooks' international subsidiaries is the local currency, foreign
currency translation adjustments do not impact operating results, but instead
are reflected as a component of stockholders' equity under the caption
"Accumulated other comprehensive income (loss)". To the extent Brooks expands
its international operations or changes its pricing practices to denominate
prices in foreign currencies, Brooks will be exposed to increased risk of
currency fluctuation.

STOCK PRICE

The stock prices of semiconductor equipment companies are subject to significant
fluctuations. Brooks' stock price may be affected by a variety of factors that
could cause the price of Brooks' common stock to fluctuate, perhaps
substantially, including: announcements of developments related to Brooks'
business; quarterly fluctuations of Brooks' actual or anticipated operating
results and order levels; general conditions in the semiconductor and flat panel
display industries or the worldwide economy; announcements of technological
innovations; new products or product enhancements by Brooks or its competitors;
developments in patents or other intellectual property rights and litigation;
and developments in Brooks' relationships with its customers and suppliers. In
addition, in recent years, both the stock market in general and the market for
shares of small capitalization and semiconductor industry-related companies in
particular have experienced extreme price fluctuations which have often been
unrelated to the operating performance of affected companies. Any such
fluctuations in the future could adversely affect the market price of Brooks'
common stock. There can be no assurance that the market price of the common
stock of Brooks will not decline.

pertinent, be in a position to deliver an unqualified opinion (other than a

compliance and the Leverage Ratio set forth in computing the Applicable Margin
(in each case without reflecting such Accounting Charges). Accounting Changes

and implemented by the Borrower.

                  (i) The words "herein", "hereof", "hereunder" and words of
         like import shall refer to this Credit Agreement as a whole and not to
         any particular section or subdivision of this Credit Agreement.

                  (j) Unless otherwise expressly indicated, in the computation
         of periods of time from a specified date to a later specified date, the
         word "from" means "from and including," the words "to" and "until" each
         mean "to but excluding," and the word "through" means "to and
         including."

                  (k) This Credit Agreement and the other Loan Documents may use
         several different limitations, tests or measurements to regulate the
         same or similar matters. All such limitations, tests and measurements
         are, however, cumulative and are to be performed in accordance with the
         terms thereof.

                  (l) This Credit Agreement and the other Loan Documents are the
         result of negotiation among, and have been reviewed by counsel to,
         among others, the Agent and the Borrower and are the product of
         discussions and negotiations among all parties. Accordingly, this
         Credit Agreement and the other Loan Documents are not intended to be
         construed against the Agent or any of the Banks merely on account of
         the Agent's or any Bank's involvement in the preparation of such
         documents.

                        2. THE REVOLVING CREDIT FACILITY.

         2.1. COMMITMENT TO LEND. Subject to the terms and conditions set forth
in this Credit Agreement, each of the Banks severally agrees to lend to the
Borrower and the Borrower may borrow, repay, and reborrow from time to time from
the Closing Date up to but not including the Revolving Credit Loan Maturity Date
upon notice by the Borrower to the Agent given in accordance with ss.2.6, such
sums as are requested by the Borrower up to a maximum aggregate amount
outstanding (after giving effect to all amounts requested) at any one time equal
to such Bank's Commitment MINUS such Bank's Commitment Percentage of the sum of
the Maximum Drawing Amount and all Unpaid Reimbursement Obligations, PROVIDED
that the sum of the outstanding amount of the Revolving Credit Loans (after
giving effect to all amounts requested) PLUS the Maximum Drawing Amount and all
Unpaid Reimbursement Obligations shall not at any time exceed the lesser of (a)
the Total Commitment and (b) the Borrowing Base. The Revolving Credit Loans
shall be made PRO RATA in accordance with each Bank's Commitment Percentage.
Each request for a Revolving Credit Loan hereunder shall constitute a
representation and warranty by the Borrower that the conditions set forth in
ss.11 and ss.12, in the case of the initial Revolving Credit Loans to be made on
the Closing Date, and ss.12, in the case of all other Revolving Credit Loans,
have been satisfied on the date of such request.

         2.2. COMMITMENT FEE. The Borrower agrees to pay to the Agent for the
accounts of the Banks in accordance with their respective Commitment Percentages
a commitment fee calculated at the applicable Commitment Fee Rate on the average
daily amount during each calendar quarter or portion thereof from the date
hereof to the Revolving Credit Loan Maturity Date by which the Total Commitment
MINUS the sum of the Maximum Drawing Amount and all Unpaid Reimbursement
Obligations exceeds the outstanding amount of Revolving Credit Loans during such
calendar quarter. The commitment fee shall be payable quarterly in arrears on
the first day of each calendar quarter for the immediately preceding calendar
quarter commencing on the first such date following the date hereof, with a
final payment on the Revolving Credit Maturity Date or any earlier date on which
the Commitments shall terminate.

         2.3. REDUCTION OF TOTAL COMMITMENT. The Borrower shall have the right
at any time and from time to time upon five (5) Business Days prior written
notice to the Agent to reduce by $1,000,000 or an integral multiple of $500,000
in excess thereof or terminate entirely the Total Commitment, whereupon the
Commitments of the Banks shall be reduced PRO RATA in accordance with their
respective Commitment Percentages of the amount specified in such notice or, as
the case may be, terminated. Promptly after receiving any notice of the Borrower
delivered pursuant to this ss.2.3, the Agent will notify the Banks of the
substance thereof. Upon the effective date of any such reduction or termination,
the Borrower shall pay to the Agent for the respective accounts of the Banks the
full amount of any commitment fee then accrued on the amount of the reduction.
No reduction or termination of the Commitments may be reinstated.

                                      -21-


         2.4. THE REVOLVING CREDIT NOTES. The Revolving Credit Loans shall be
evidenced by separate promissory notes of the Borrower in substantially the form
of EXHIBIT B hereto (each a "Revolving Credit Note"), dated as of the Closing
Date and completed with appropriate insertions. One Revolving Credit Note shall
be payable to the order of each Bank in a principal amount equal to such Bank's
Commitment or, if less, the outstanding amount of all Revolving Credit Loans
made by such Bank, plus interest accrued thereon, as set forth below. The
Borrower irrevocably authorizes each Bank to make or cause to be made, at or
about the time of the Drawdown Date of any Revolving Credit Loan or at the time
of receipt of any payment of principal on such Bank's Revolving Credit Note, an
appropriate notation on such Bank's Revolving Credit Note Record reflecting the
making of such Revolving Credit Loan or (as the case may be) the receipt of such
payment. The outstanding amount of the Revolving Credit Loans set forth on such
Bank's Record shall be PRIMA FACIE evidence of the principal amount thereof
owing and unpaid to such Bank, but the failure to record, or any error in so
recording, any such amount on such Bank's Record shall not limit or otherwise
affect the obligations of the Borrower hereunder or under any Revolving Credit
Note to make payments of principal of or interest on any Revolving Credit Note
when due.

         2.5. INTEREST ON REVOLVING CREDIT LOANS. Except as otherwise provided
in ss.5.11,

                  (a) Each Base Rate Loan shall bear interest for the period
         commencing with the Drawdown Date thereof and ending on the last day of
         the Interest Period with respect thereto at the rate per annum equal to
         the Base Rate PLUS the Applicable Margin.

                  (b) Each LIBOR Rate Loan shall bear interest for the period
         commencing with the Drawdown Date thereof and ending on the last day of
         the Interest Period with respect thereto at the rate per annum equal to
         the LIBOR Rate determined for such Interest Period PLUS the Applicable
         Margin.

                  (c) The Borrower promises to pay interest on each Revolving
         Credit Loan in arrears on each Interest Payment Date with respect
         thereto.

         2.6.  REQUESTS FOR REVOLVING CREDIT LOANS.

                  2.6.1. GENERAL. The Borrower shall give to the Agent written
         notice in the form of EXHIBIT C hereto (or telephonic notice confirmed
         in a writing in the form of EXHIBIT C hereto) of each Revolving Credit
         Loan requested hereunder (a "Loan Request") no later than (a) 10:00
         a.m. (Chicago time) on the proposed Drawdown Date of any Base Rate Loan
         and (b) 10:00 a.m. (Chicago time) two (2) LIBOR Business Days prior to
         the proposed Drawdown Date of any LIBOR Rate Loan. Each such notice
         shall specify (i) the principal amount of the Revolving Credit Loan
         requested, (ii) the proposed Drawdown Date of such Revolving Credit
         Loan, (iii) the Interest Period for such Revolving Credit

<PAGE>   28
                                      -22-


         Loan and (iv) the Type of such Revolving Credit Loan. Promptly upon
         receipt of any such notice, the Agent shall notify each of the Banks
         thereof. Each Loan Request shall be irrevocable and binding on the
         Borrower and shall obligate the Borrower to accept the Revolving Credit
         Loan requested from the Banks on the proposed Drawdown Date. Each Loan
         Request for a Base Rate Loan shall be in a minimum aggregate amount of
         $250,000 or an integral multiple thereof, and each Loan Request for a
         LIBOR Rate Loan shall be in a minimum aggregate amount of $500,000 or
         an integral multiple thereof.

         2.7.  CONVERSION OPTIONS.

                  2.7.1. CONVERSION TO DIFFERENT TYPE OF REVOLVING CREDIT LOAN.
         The Borrower may elect from time to time to convert any outstanding
         Revolving Credit Loan to a Revolving Credit Loan of another Type,
         PROVIDED that (a) with respect to any such conversion of a LIBOR Rate
         Loan to a Base Rate Loan, the Borrower shall give the Agent at least
         two (2) Business Days prior written notice of such election; (b) with
         respect to any such conversion of a Base Rate Loan to a LIBOR Rate
         Loan, the Borrower shall give the Agent at least two (2) LIBOR Business
         Days prior written notice of such election; (c) with respect to any
         such conversion of a LIBOR Rate Loan into a Revolving Credit Loan of
         another Type, such conversion shall only be made on the last day of the
         Interest Period with respect thereto and (d) no Revolving Credit Loan
         may be converted into a LIBOR Rate Loan when any Default or Event of
         Default has occurred and is continuing. On the date on which such
         conversion is being made each Bank shall take such action as is
         necessary to transfer its Commitment Percentage of such Revolving
         Credit Loans to its Domestic Lending Office or its LIBOR Lending
         Office, as the case may be. All or any part of outstanding Revolving
         Credit Loans of any Type may be converted into a Revolving Credit Loan
         of another Type as provided herein, PROVIDED that any partial
         conversion shall be in an aggregate principal amount of $500,000 or a
         whole multiple thereof. Each Conversion Request relating to the
         conversion of a Revolving Credit Loan to a LIBOR Rate Loan shall be
         irrevocable by the Borrower.

                  2.7.2. CONTINUATION OF TYPE OF REVOLVING CREDIT LOAN. Any
         Revolving Credit Loan of any Type may be continued as a Revolving
         Credit Loan of the same Type upon the expiration of an Interest Period
         with respect thereto by compliance by the Borrower with the notice
         provisions contained in ss.2.7.1; PROVIDED that no LIBOR Rate Loan may
         be continued as such when any Default or Event of Default has occurred
         and is continuing, but shall be automatically converted to a Base Rate
         Loan on the last day of the first Interest Period relating thereto
         ending during the continuance of any Default or Event of Default of
         which officers of the Agent active upon the Borrower's account have
         actual knowledge. In the event that the Borrower fails to provide any
         such notice with respect to the continuation of any LIBOR Rate Loan as
         such,



<PAGE>   29
                                      -23-


         then such LIBOR Rate Loan shall be automatically converted to a Base
         Rate Loan on the last day of the first Interest Period relating
         thereto. The Agent shall notify the Banks promptly when any such
         automatic conversion contemplated by this ss.2.7 is scheduled to occur.

                  2.7.3. LIBOR RATE LOANS. Any conversion to or from LIBOR Rate
         Loans shall be in such amounts and be made pursuant to such elections
         so that, after giving effect thereto, the aggregate principal amount of
         all LIBOR Rate Loans having the same Interest Period shall not be less
         than $500,000 or a whole multiple of $500,000 in excess thereof.

         2.8.  FUNDS FOR REVOLVING CREDIT LOAN.

                  2.8.1. FUNDING PROCEDURES. Not later than 11:00 a.m. (Chicago
         time) on the proposed Drawdown Date of any Revolving Credit Loans, each
         of the Banks will make available to the Agent, at the Agent's Head
         Office, in immediately available funds, the amount of such Bank's
         Commitment Percentage of the amount of the requested Revolving Credit
         Loans. Upon receipt from each Bank of such amount, and upon receipt of
         the documents required by ss.ss.11 and 12 and the satisfaction of the
         other conditions set forth therein, to the extent applicable, the Agent
         will make available to the Borrower the aggregate amount of such
         Revolving Credit Loans made available to the Agent by the Banks. The
         failure or refusal of any Bank to make available to the Agent at the
         aforesaid time and place on any Drawdown Date the amount of its
         Commitment Percentage of the requested Revolving Credit Loans shall not
         relieve any other Bank from its several obligation hereunder to make
         available to the Agent the amount of such other Bank's Commitment
         Percentage of any requested Revolving Credit Loans.

                  2.8.2. ADVANCES BY AGENT. The Agent may, unless notified to
         the contrary by any Bank prior to a Drawdown Date, assume that such
         Bank has made available to the Agent on such Drawdown Date the amount
         of such Bank's Commitment Percentage of the Revolving Credit Loans to
         be made on such Drawdown Date, and the Agent may (but it shall not be
         required to), in reliance upon such assumption, make available to the
         Borrower a corresponding amount. If any Bank makes available to the
         Agent such amount on a date after such Drawdown Date, such Bank shall
         pay to the Agent on demand an amount equal to the product of (a) the
         average computed for the period referred to in clause (c) below, of the
         weighted average interest rate paid by the Agent for federal funds
         acquired by the Agent during each day included in such period, TIMES
         (b) the amount of such Bank's Commitment Percentage of such Revolving
         Credit Loans, TIMES (c) a fraction, the numerator of which is the
         number of days that elapse from and including such Drawdown Date to the
         date on which the amount of such Bank's Commitment Percentage of such
         Revolving Credit Loans shall become immediately available to the Agent,
         and the denominator of which is 365. A statement of the Agent


<PAGE>   30
                                      -24-



         submitted to such Bank with respect to any amounts owing under this
         paragraph shall be PRIMA FACIE evidence of the amount due and owing to
         the Agent by such Bank. If the amount of such Bank's Commitment
         Percentage of such Revolving Credit Loans is not made available to the
         Agent by such Bank within three (3) Business Days following such
         Drawdown Date, the Agent agrees to provide the Borrower with notice of
         such events (PROVIDED, the Agent shall not be liable for any failure to
         so deliver such notice and the failure by the Agent to provide the
         Borrower with any such notice shall in no manner alter the Borrower's
         obligations under this ss.2.8.2) and the Agent shall be entitled to
         recover such amount from the Borrower on demand, with interest thereon
         at the rate per annum applicable to the Revolving Credit Loans made on
         such Drawdown Date.

         2.9. CHANGE IN BORROWING BASE. The Borrowing Base shall be determined
quarterly (or at such other interval as may be specified pursuant to ss.8.4(e))
by the Agent by reference to the Borrowing Base Report delivered to the Banks
and the Agent pursuant to ss.8.4(e). The Agent shall give to the Borrower
written notice of any change in the Borrowing Base determined by the Agent. In
the case of a reduction in the lending formula with respect to Eligible Accounts
Receivable, such notice shall be effective ten (10) days after its receipt by
the Borrower.

                   3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

         3.1. MATURITY. The Borrower promises to pay on the Revolving Credit
Loan Maturity Date, and there shall become absolutely due and payable on the
Revolving Credit Loan Maturity Date, all of the Revolving Credit Loans
outstanding on such date, together with any and all accrued and unpaid interest
thereon.

         3.2. MANDATORY REPAYMENTS OF REVOLVING CREDIT LOANS. If at any time the
sum of the outstanding amount of the Revolving Credit Loans, the Maximum Drawing
Amount and all Unpaid Reimbursement Obligations exceeds the lesser of (a) the
Total Commitment and (b) the Borrowing Base, then the Borrower shall immediately
pay the amount of such excess to the Agent for the respective accounts of the
Banks for application: first, to any Unpaid Reimbursement Obligations; second,
to the Revolving Credit Loans; and third, to provide to the Agent cash
collateral for Reimbursement Obligations as contemplated by ss.4.2(b) and (c).
Each payment of any Unpaid Reimbursement Obligations or prepayment of Revolving
Credit Loans shall be allocated among the Banks, in proportion, as nearly as
practicable, to each Reimbursement Obligation or (as the case may be) the
respective unpaid principal amount of each Bank's Revolving Credit Note, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.

         3.3. OPTIONAL REPAYMENTS OF REVOLVING CREDIT LOANS. The Borrower shall
have the right, at its election, to repay the outstanding amount of the
Revolving Credit Loans, as a whole or in part, at any time without penalty or




<PAGE>   31
                                      -25-


premium, PROVIDED that any full or partial prepayment of the outstanding amount
of any LIBOR Rate Loans pursuant to this ss.3.3 may be made only on the last day
of the Interest Period relating thereto. The Borrower shall give the Agent, no
later than 10:00 a.m., Chicago time, at least one (1) Business Days prior
written notice of any proposed prepayment pursuant to this ss.3.3 of Base Rate
Loans, and two (2) LIBOR Business Days notice of any proposed prepayment
pursuant to this ss.3.3 of LIBOR Rate Loans, in each case specifying the
proposed date of prepayment of Revolving Credit Loans and the principal amount
to be prepaid. Each such partial prepayment of the Revolving Credit Loans shall
be in an aggregate amount of $500,000 or integral multiple of $250,000 in excess
thereof, shall be accompanied by the payment of accrued interest on the
principal prepaid to the date of prepayment and shall be applied, in the absence
of instruction by the Borrower, first to the principal of Base Rate Loans and
then to the principal of LIBOR Rate Loans. Each partial prepayment shall be
allocated among the Banks, in proportion, as nearly as practicable, to the
respective unpaid principal amount of each Bank's Revolving Credit Note, with
adjustments to the extent practicable to equalize any prior repayments not
exactly in proportion.

                              4. LETTERS OF CREDIT.

         4.1.  LETTER OF CREDIT COMMITMENTS.

                  4.1.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the
         terms and conditions hereof and the execution and delivery by the
         Borrower of a letter of credit application on the Agent's customary
         form (a "Letter of Credit Application"), the Agent on behalf of the
         Banks and in reliance upon the agreement of the Banks set forth in
         ss.4.1.4 and upon the representations and warranties of the Borrower
         contained herein, agrees, in its individual capacity, to issue, extend
         and renew for the account of the Borrower one or more standby or
         documentary letters of credit (individually, a "Letter of Credit"), in
         such form as may be requested from time to time by the Borrower and
         agreed to by the Agent; PROVIDED, HOWEVER, that after giving effect to
         such request, the sum of (a) the Maximum Drawing Amount on all Letters
         of Credit, (b) all Unpaid Reimbursement Obligations, and (c) the amount
         of all Revolving Credit Loans outstanding shall not exceed the lesser
         of (i) the Total Commitment and (ii) the Borrowing Base.
         Notwithstanding the foregoing, except in connection with Letters of
         Credit issued to support Indebtedness assumed or incurred in any
         connection with any Permitted Acquisition, the Agent shall have no
         obligation to issue any Letter of Credit to support or secure any
         Indebtedness of the Borrower or any of its Subsidiaries to the extent
         that such Indebtedness was incurred prior to the proposed issuance date
         of such Letter of Credit, unless in any such case the Borrower
         demonstrates to the satisfaction of the Agent that (x) such prior
         incurred Indebtedness were then fully secured by a prior perfected and
         unavoidable security interest in collateral provided by the Borrower or
         such Subsidiary to the proposed beneficiary of such Letter of Credit or
         (y) such prior incurred Indebtedness were then




<PAGE>   32
                                      -26-


         secured or supported by a letter of credit issued for the account of
         the Borrower or such Subsidiary and the reimbursement obligation with
         respect to such letter of credit was fully secured by a prior perfected
         and unavoidable security interest in collateral provided to the issuer
         of such letter of credit by the Borrower or such Subsidiary.

                  4.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
         Application shall be completed to the satisfaction of the Agent. In the
         event that any provision of any Letter of Credit Application shall be
         inconsistent with any provision of this Credit Agreement, then the
         provisions of this Credit Agreement shall, to the extent of any such
         inconsistency, govern.

                  4.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit
         issued, extended or renewed hereunder shall, among other things, (a)
         provide for the payment of sight drafts for honor thereunder when
         presented in accordance with the terms thereof and when accompanied by
         the documents described therein, and (b) have an expiry date no later
         than the date which is fourteen (14) days (or, if the Letter of Credit
         is confirmed by a confirmer or otherwise provides for one or more
         nominated persons, forty-five (45) days) prior to the Revolving Credit
         Loan Maturity Date. Each Letter of Credit so issued, extended or
         renewed shall be subject to the Uniform Customs or, in the case of a
         standby Letter of Credit, either the Uniform Customs or the
         International Standby Practices.

                  4.1.4. REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank severally
         agrees that it shall be absolutely liable, without regard to the
         occurrence of any Default or Event of Default or any other condition
         precedent whatsoever, to the extent of such Bank's Commitment
         Percentage, to reimburse the Agent on demand for the amount of each
         draft paid by the Agent under each Letter of Credit to the extent that
         such amount is not reimbursed by the Borrower pursuant to ss.4.2 (such
         agreement for a Bank being called herein the "Letter of Credit
         Participation" of such Bank).

                  4.1.5. PARTICIPATIONS OF BANKS. Each such payment made by a
         Bank shall be treated as the purchase by such Bank of a participating
         interest in the Borrower's Reimbursement Obligation under ss.4.2 in an
         amount equal to such payment. Each Bank shall share in accordance with
         its participating interest in any interest which accrues pursuant to
         ss.4.2.

         4.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce the
Agent to issue, extend and renew each Letter of Credit and the Banks to
participate therein, the Borrower hereby agrees to reimburse or pay to the
Agent, for the account of the Agent or (as the case may be) the Banks, with
respect to each Letter of Credit issued, extended or renewed by the Agent
hereunder,


<PAGE>   33
                                      -27-


                  (a) except as otherwise expressly provided in ss.4.2(b) and
         (c), on each date that any draft presented under such Letter of Credit
         is honored by the Agent, or the Agent otherwise makes a payment with
         respect thereto, (i) the amount paid by the Agent under or with respect
         to such Letter of Credit, and (ii) the amount of any taxes, fees,
         charges or other costs and expenses whatsoever incurred by the Agent or
         any Bank in connection with any payment made by the Agent or any Bank
         under, or with respect to, such Letter of Credit,

                  (b) upon the reduction (but not termination) of the Total
         Commitment to an amount less than the Maximum Drawing Amount, an amount
         equal to such difference, which amount shall be held by the Agent for
         the benefit of the Banks and the Agent as cash collateral for all
         Reimbursement Obligations, and

                  (c) upon the termination of the Total Commitment, or the
         acceleration of the Reimbursement Obligations with respect to all
         Letters of Credit in accordance with ss.13, an amount equal to the then
         Maximum Drawing Amount on all Letters of Credit, which amount shall be
         held by the Agent for the benefit of the Banks and the Agent as cash
         collateral for all Reimbursement Obligations.

Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrower under this ss.4.2 at any time from the date such amounts become due
and payable (whether as stated in this ss.4.2, by acceleration or otherwise)
until payment in full (whether before or after judgment) shall be payable to the
Agent on demand at the rate specified in ss.5.11 for overdue principal on the
Revolving Credit Loans.

         4.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or
other demand for payment shall be made under any Letter of Credit, the Agent
shall notify the Borrower of the date and amount of the draft presented or
demand for payment and of the date and time when it expects to pay such draft or
honor such demand for payment. If the Borrower fails to reimburse the Agent as
provided in ss.4.2 on or before the date that such draft is paid or other
payment is made by the Agent, the Agent may at any time thereafter notify the
Banks of the amount of any such Unpaid Reimbursement Obligation. No later than
3:00 p.m. (Chicago time) on the Business Day next following the receipt of such
notice, each Bank shall make available to the Agent, at the Agent's Head Office,
in immediately available funds, such Bank's Commitment Percentage of such Unpaid
Reimbursement Obligation, together with an amount equal to the product of (a)
the average, computed for the period referred to in clause (c) below, of the
weighted average interest rate paid by the Agent for federal funds acquired by
the Agent during each day included in such period, TIMES (b) the amount equal to
such Bank's Commitment Percentage of such Unpaid Reimbursement Obligation, TIMES
(c) a fraction, the numerator of which is the number of days that elapse from
and including the date the Agent paid the draft presented for honor or otherwise
made payment to the date on which such


<PAGE>   34
                                      -28-


Bank's Commitment Percentage of such Unpaid Reimbursement obligation shall
become immediately available to the Agent, and the denominator of which is 360.
The responsibility of the Agent to the Borrower and the Banks shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity in all
material respects with such Letter of Credit.

         4.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this ss.4
shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Agent, any Bank or any
beneficiary of a Letter of Credit. The Borrower further agrees with the Agent
and the Banks that the Agent and the Banks shall not be responsible for, and the
Borrower's Reimbursement Obligations under ss.4.2 shall not be affected by,
among other things, the validity or genuineness of documents or of any
endorsements thereon, even if such documents should in fact prove to be in any
or all respects invalid, fraudulent or forged, or any dispute between or among
the Borrower, the beneficiary of any Letter of Credit or any financing
institution or other party to which any Letter of Credit may be transferred or
any claims or defenses whatsoever of the Borrower against the beneficiary of any
Letter of Credit or any such transferee. The Agent and the Banks shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit. The Borrower agrees that any action taken or omitted by
the Agent or any Bank under or in connection with each Letter of Credit and the
related drafts and documents, if done in good faith, shall be binding upon the
Borrower and shall not result in any liability on the part of the Agent or any
Bank to the Borrower.

         4.5. RELIANCE BY ISSUER. To the extent not inconsistent with ss.4.4,
the Agent shall be entitled to rely, and shall be fully protected in relying
upon, any Letter of Credit, draft, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel, independent accountants and
other experts selected by the Agent. The Agent shall be fully justified in
failing or refusing to take any action under this Credit Agreement unless it
shall first have received such advice or concurrence of the Majority Banks as it
reasonably deems appropriate or it shall first be indemnified to its reasonable
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Credit Agreement in accordance with a request of the Majority
Banks, and such request and any action taken or failure to act pursuant thereto
shall be binding upon the Banks and all future holders of the Revolving Credit
Notes or of a Letter of Credit Participation.

                                      -29-


         4.6. LETTER OF CREDIT FEE. The Borrower shall pay a fee (in each case,
a "Letter of Credit Fee") to the Agent in respect of each Letter of Credit an
amount equal to the Letter of Credit Rate per annum of the face amount of such
standby Letter of Credit, which Letter of Credit Fee shall be for the accounts
of the Banks in accordance with their respective Commitment Percentages. Such
Letter of Credit Fee shall be due and payable quarterly in arrears. In respect
of each Letter of Credit, the Borrower shall also pay to the Agent for the
Agent's own account, at such other time or times as such charges are customarily
made by the Agent, the Agent's customary issuance, amendment, negotiation or
document examination and other administrative fees as in effect from time to
time.

                         5. CERTAIN GENERAL PROVISIONS.

         5.1. CLOSING . The Borrower agrees to pay to the Agent for the PRO RATA
accounts of the Banks on the Closing Date a closing fee in the amount set forth
in the Syndication Side Letter.

         5.2. OTHER FEES. The Borrower shall pay to the Agent those other fees,
if any, provided for in the Syndication Side Letter, such fees to be due and
payable at the times specified in such Syndication Side Letter.

         5.3.  FUNDS FOR PAYMENTS.

                  5.3.1. PAYMENTS TO AGENT. All payments of principal, interest,
         Reimbursement Obligations, commitment fees, Letter of Credit Fees and
         any other amounts due hereunder or under any of the other Loan
         Documents shall be made on the due date thereof to the Agent in
         Dollars, for the respective accounts of the Banks and the Agent, at the
         Agent's Head Office or at such other place that the Agent may from time
         to time designate, in each case at or about 11:00 a.m. (Chicago,
         Illinois, time or other local time at the place of payment) and in
         immediately available funds.

                  5.3.2. NO OFFSET, ETC. All payments by the Borrower hereunder
         and under any of the other Loan Documents shall be made without
         recoupment, setoff or counterclaim and free and clear of and without
         deduction for any taxes, levies, imposts, duties, charges, fees,
         deductions, withholdings, compulsory loans, restrictions or conditions
         of any nature now or hereafter imposed or levied by any jurisdiction or
         any political subdivision thereof or taxing or other authority therein
         unless the Borrower is compelled by law to make such deduction or
         withholding. If any such obligation is imposed upon the Borrower with
         respect to any amount payable by it hereunder or under any of the other
         Loan Documents, the Borrower will pay to the Agent, for the account of
         the Banks or (as the case may be) the Agent, on the date on which such
         amount is due and payable hereunder or under such other Loan Document,
         such additional amount in Dollars as shall be necessary to enable the
         Banks or the Agent to receive the same net amount which the



<PAGE>   36
                                      -30-


         Banks or the Agent would have received on such due date had no such
         obligation been imposed upon the Borrower. The Borrower will deliver
         promptly to the Agent certificates or other valid vouchers for all
         taxes or other charges deducted from or paid with respect to payments
         made by the Borrower hereunder or under such other Loan Document.

         5.4. COMPUTATIONS. All computations of interest on the Base Rate Loans
and of commitment fees, Letter of Credit Fees or other fees shall, unless
otherwise expressly provided herein, be based on a 365-day year and paid for the
actual number of days elapsed, and all computations of interest on the LIBOR
Rate Loans shall be based on a 360-day year and paid for the actual number of
days elapsed. Except as otherwise provided in the definition of the term
"Interest Period" with respect to LIBOR Rate Loans, whenever a payment hereunder
or under any of the other Loan Documents becomes due on a day that is not a
Business Day, the due date for such payment shall be extended to the next
succeeding Business Day, and interest shall accrue during such extension. The
outstanding amount of the Revolving Credit Loans as reflected on the Records
from time to time shall be considered correct and binding on the Borrower unless
within five (5) Business Days after receipt of any notice by the Agent or any of
the Banks of such outstanding amount, the Agent or such Bank shall notify the
Borrower to the contrary.

         5.5. INABILITY TO DETERMINE LIBOR RATE. In the event, prior to the
commencement of any Interest Period relating to any LIBOR Rate Loan, the Agent
shall determine or be notified by the Majority Banks that adequate and
reasonable methods do not exist for ascertaining the LIBOR Rate that would
otherwise determine the rate of interest to be applicable to any LIBOR Rate Loan
during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks. In such event (a) any Loan Request or
Conversion Request with respect to LIBOR Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (b) each LIBOR Rate
Loan will automatically, on the last day of the then current Interest Period
relating thereto, become a Base Rate Loan, and (c) the obligations of the Banks
to make LIBOR Rate Loans shall be suspended until the Agent or the Majority
Banks determine that the circumstances giving rise to such suspension no longer
exist, whereupon the Agent or, as the case may be, the Agent upon the
instruction of the Majority Banks, shall so notify the Borrower and the Banks.

         5.6. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain
LIBOR Rate Loans, such Bank shall forthwith give notice of such circumstances to
the Borrower and the other Banks and thereupon (a) the commitment of such Bank
to make LIBOR Rate Loans or convert Revolving Credit Loans of another Type to
LIBOR Rate Loans shall forthwith be suspended and (b) such Bank's Revolving
Credit Loans then outstanding as LIBOR Rate Loans, if any, shall be converted
automatically to Base Rate Loans on the last day of each Interest Period
applicable to such LIBOR Rate Loans or within such earlier


<PAGE>   37
                                      -31-


period as may be required by law. The Borrower hereby agrees promptly to pay the
Agent for the account of such Bank, upon demand by such Bank, any additional
amounts necessary to compensate such Bank for any costs incurred by such Bank in
making any conversion in accordance with this ss.5.6, including any interest or
fees payable by such Bank to lenders of funds obtained by it in order to make or
maintain its LIBOR Rate Loans hereunder.

         5.7. ADDITIONAL COSTS, ETC. If any present or future applicable law,
which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Bank or the Agent by any central bank or other fiscal,
monetary or other authority (whether or not having the force of law), shall:

                  (a) subject any Bank or the Agent to any tax, levy, impost,
         duty, charge, fee, deduction or withholding of any nature with respect
         to this Credit Agreement, the other Loan Documents, any Letters of
         Credit, such Bank's Commitment or the Revolving Credit Loans (other
         than taxes based upon or measured by the income or profits of such Bank
         or the Agent), or

                  (b) materially change the basis of taxation (except for
         changes in taxes on income or profits) of payments to any Bank of the
         principal of or the interest on any Revolving Credit Loans or any other
         amounts payable to any Bank or the Agent under this Credit Agreement or
         any of the other Loan Documents, or

                  (c) impose or increase or render applicable (other than to the
         extent specifically provided for elsewhere in this Credit Agreement)
         any special deposit, reserve, assessment, liquidity, capital adequacy
         or other similar requirements (whether or not having the force of law)
         against assets held by, or deposits in or for the account of, or loans
         by, or letters of credit issued by, or commitments of an office of any
         Bank, or

                  (d) impose on any Bank or the Agent any other conditions or
         requirements with respect to this Credit Agreement, the other Loan
         Documents, any Letters of Credit, the Revolving Credit Loans, such
         Bank's Commitment, or any class of loans, letters of credit or
         commitments of which any of the Revolving Credit Loans or such Bank's
         Commitment forms a part, and the result of any of the foregoing is

                           (i) to increase the cost to any Bank of making,
                  funding, issuing, renewing, extending or maintaining any of
                  the Revolving Credit Loans or such Bank's Commitment or any
                  Letter of Credit, or



<PAGE>   38
                                      -32-


                           (ii) to reduce the amount of principal, interest,
                  Reimbursement Obligation or other amount payable to such Bank
                  or the Agent hereunder on account of such Bank's Commitment,
                  any Letter of Credit or any of the Revolving Credit Loans, or

                           (iii) to require such Bank or the Agent to make any
                  payment or to forego any interest or Reimbursement Obligation
                  or other sum payable hereunder, the amount of which payment or
                  foregone interest or Reimbursement Obligation or other sum is
                  calculated by reference to the gross amount of any sum
                  receivable or deemed received by such Bank or the Agent from
                  the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by such Bank or
(as the case may be) the Agent at any time and from time to time and as often as
the occasion therefor may arise, pay to such Bank or the Agent such additional
amounts as will be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or Reimbursement
Obligation or other sum, PROVIDED that the Borrower shall not be liable to any
Bank or the Agent for costs incurred more than sixty (60) days prior to receipt
by the Borrower of such demand for payment from such Bank or, as the case may
be, the Agent, unless such costs were incurred prior to such sixty (60) day
period as a result of such present or future applicable law being retroactive to
a date which occurred prior to such sixty (60) day period.

         5.8. CAPITAL ADEQUACY. If after the date hereof any Bank or the Agent
determines that (a) the adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by a court or governmental
authority with appropriate jurisdiction, or (b) compliance by such Bank or the
Agent or any corporation controlling such Bank or the Agent with any law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) of any such entity regarding capital adequacy, has the
effect of reducing the return on such Bank's or the Agent's commitment with
respect to any Revolving Credit Loans to a level below that which such Bank or
the Agent could have achieved but for such adoption, change or compliance
(taking into consideration such Bank's or the Agent's then existing policies
with respect to capital adequacy and assuming full utilization of such entity's
capital) by any amount deemed by such Bank or (as the case may be) the Agent to
be material, then such Bank or the Agent may notify the Borrower of such fact.
To the extent that the amount of such reduction in the return on capital is not
reflected in the Base Rate, the Borrower and such Bank shall thereafter attempt
to negotiate in good faith, within thirty (30) days of the day on which the
Borrower receives such notice, an adjustment payable hereunder that will
adequately compensate such Bank in light of these circumstances. If the Borrower
and such Bank are unable to agree to such adjustment within thirty (30) days of
the date on which the Borrower receives such notice, then commencing on the date
of such notice (but not earlier than the effective date of


<PAGE>   39
                                      -33-



any such increased capital requirement), the fees payable hereunder shall
increase by an amount that will, in such Bank's reasonable determination,
provide adequate compensation; PROVIDED that the Borrower shall not be liable to
any Bank or the Agent for costs incurred more than sixty (60) days prior to
receipt by the Borrower of the notice referred to in the immediately preceding
sentence from such Bank or the Agent, as the case may be. Each Bank shall
allocate such cost increases among its customers in good faith and on an
equitable basis.

         5.9. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to ss.ss.5.7 or 5.8 and a reasonably detailed explanation of
such amounts which are due, submitted by any Bank or the Agent to the Borrower,
shall be conclusive, absent manifest error, that such amounts are due and owing.

         5.10. INDEMNITY. The Borrower agrees to indemnify each Bank and to hold
each Bank harmless from and against any loss, cost or expense (including loss of
anticipated profits) that such Bank may sustain or incur as a consequence of (a)
default by the Borrower in payment of the principal amount of or any interest on
any LIBOR Rate Loans as and when due and payable, including any such loss or
expense arising from interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its LIBOR Rate Loans, (b) default by the
Borrower in making a borrowing or conversion after the Borrower has given (or is
deemed to have given) a Loan Request or a Conversion Request relating thereto in
accordance with ss.2.6 or ss.2.7 or (c) the making of any payment of a LIBOR
Rate Loan or the making of any conversion of any such Revolving Credit Loan to a
Base Rate Loan on a day that is not the last day of the applicable Interest
Period with respect thereto, including interest or fees payable by such Bank to
lenders of funds obtained by it in order to maintain any such Revolving Credit
Loans.

         5.11.  INTEREST AFTER DEFAULT.

                  5.11.1. OVERDUE AMOUNTS. Overdue principal and (to the extent
         permitted by applicable law) interest on the Revolving Credit Loans and
         all other overdue amounts payable hereunder or under any of the other
         Loan Documents shall bear interest compounded monthly and payable on
         demand at a rate per annum equal to two percent (2%) above the rate of
         interest otherwise applicable to such Revolving Credit Loans pursuant
         to ss.2.5 until such amount shall be paid in full (after as well as
         before judgment).

                  5.11.2. AMOUNTS NOT OVERDUE. During the continuance of a
         Default or an Event of Default the principal of the Revolving Credit
         Loans not overdue shall, until such Default or Event of Default has
         been cured or remedied or such Default or Event of Default has been
         waived by the Majority Banks pursuant to ss.26, bear interest at a rate
         per annum equal to two percent (2%) above the rate of interest
         otherwise applicable to such Revolving Credit Loans pursuant to ss.2.5.




<PAGE>   40
                                      -34-


         5.12. REPLACEMENT OF BANKS. Within thirty (30) days after (a) any Bank
had demanded compensation from the Borrower pursuant to ss.ss.5.7 or 5.8 hereof,
or (b) there shall have occurred a change in law with respect to any Bank as a
consequence of which it shall have become unlawful for such Bank to make a LIBOR
Rate Loan on any Drawdown Date, as described in ss.5.6 hereof (any such Bank
described in the foregoing clauses (a) or (b) is hereinafter referred to as an
"Affected Bank"), the Borrower may request that the other Banks (collectively,
the "Non-Affected Banks") acquire all, but not less than all, of the Affected
Bank's Commitment or may designate a replacement bank or banks, which must be an
Eligible Assignee and which also must be reasonably acceptable to the Agent, to
acquire and assume all or any portion of the outstanding Revolving Credit Loans
and Commitment of the Affected Bank (the "Replacement Bank"). If the Borrower so
requests the Non-Affected Banks to acquire all or a portion of the Affected
Bank's Commitment, the Non-Affected Banks may elect to acquire all or any
portion of the Affected Banks outstanding Revolving Credit Loans and to assume
all or any portion of the Affected Bank's Commitment. If the Non-Affected Banks
do not elect to acquire and assume all or any portion of the Affected Bank's
outstanding Revolving Credit Loans and Commitment, the Replacement Bank may
acquire and assume that portion of the outstanding Revolving Credit Loans and
Commitments of the Affected Bank not otherwise acquired or assumed by the
Non-Affected Banks. The provisions of ss.19 hereof shall apply to all
reallocations pursuant to this ss.5.12, and the Affected Bank and any
Non-Affected Banks and/or replacement banks which are to acquire the Revolving
Credit Loans and Commitment of the Affected Bank shall execute and deliver to
the Agent, in accordance with the provisions of ss.19 hereof, such Assignments
and Acceptances and other instruments, including, without limitation, the
Revolving Credit Notes, as are required pursuant to ss.19 hereof to give effect
to such reallocations. On the effective date of the applicable Assignment and
Acceptance, the Borrower shall pay to the Affected Bank all interest accrued on
its Revolving Credit Loans up to but excluding such date, along with any fees
payable to such Affected Bank hereunder up to but excluding such date.

                                 6. GUARANTIES.

         6.1. GUARANTIES OF SUBSIDIARIES. The Obligations shall be guaranteed
pursuant to the terms of the Guaranty.

                       7. REPRESENTATIONS AND WARRANTIES.

         The Borrower represents and warrants to the Banks and the Agent as
follows:

         7.1.  CORPORATE AUTHORITY.

                  7.1.1. INCORPORATION; GOOD STANDING. Each of the Borrower and
         the Guarantors (a) is a corporation duly organized, validly existing
         and in good standing under the laws of its state or other jurisdiction
         of incorporation, (b) has all requisite corporate power to own its
         property




<PAGE>   41
                                      -35-


         and conduct its business as now conducted and as presently
         contemplated, and (c) is in good standing as a foreign corporation and
         is duly authorized to do business in each jurisdiction where such
         qualification is necessary except where a failure to be so qualified
         would not have a Material Adverse Effect.

                  7.1.2. AUTHORIZATION. The execution, delivery and performance
         of this Credit Agreement and the other Loan Documents to which the
         Borrower or any Guarantor is or is to become a party and the
         transactions contemplated hereby and thereby (a) are within the
         corporate authority of such Person, (b) have been duly authorized by
         all necessary corporate proceedings, (c) do not conflict with or result
         in any breach or contravention of any provision of law, statute, rule
         or regulation to which the Borrower or any Guarantor is subject or any
         judgment, order, writ, injunction, license or permit applicable to the
         Borrower or any Guarantor and (d) do not conflict with any provision of
         the corporate charter or bylaws of, or any agreement or other
         instrument binding upon, the Borrower or any Guarantor.

                  7.1.3. ENFORCEABILITY. The execution and delivery of this
         Credit Agreement and the other Loan Documents to which the Borrower or
         any Guarantor is or is to become a party will result in valid and
         legally binding obligations of such Person enforceable against it in
         accordance with the respective terms and provisions hereof and thereof,
         except as enforceability is limited by bankruptcy, insolvency,
         reorganization, moratorium or other laws relating to or affecting
         generally the enforcement of creditors' rights and except to the extent
         that availability of the remedy of specific performance or injunctive
         relief is subject to the discretion of the court before which any
         proceeding therefor may be brought.

         7.2. GOVERNMENTAL APPROVALS. The execution, delivery and performance by
the Borrower and any Guarantor of this Credit Agreement and the other Loan
Documents to which the Borrower or any Guarantor is or is to become a party and
the transactions contemplated hereby and thereby do not require the approval or
consent of, or filing with, any governmental agency or authority other than
those already obtained.

         7.3. TITLE TO PROPERTIES; LEASES. Except as indicated on SCHEDULE 7.3
hereto, the Borrower and its Subsidiaries own all of the assets reflected in the
consolidated balance sheet of the Borrower and its Subsidiaries as at the
Balance Sheet Date or acquired since that date (except property and assets sold
or otherwise disposed of in the ordinary course of business since that date),
subject to no rights of others, including any mortgages, leases, conditional
sales agreements, title retention agreements, liens or other encumbrances except
Permitted Liens.

         7.4.  FINANCIAL STATEMENTS, PROJECTIONS AND SOLVENCY.

                                      -36-


                  7.4.1. FISCAL YEAR. The Borrower and each Guarantor has a
         fiscal year which is the twelve months ending on September 30 of each
         calendar year.

                  7.4.2. FINANCIAL STATEMENTS. There has been furnished to each
         of the Banks a consolidated balance sheet of the Borrower and its
         Subsidiaries as at the Balance Sheet Date, and a consolidated statement
         of income of the Borrower and its Subsidiaries for the fiscal year then
         ended, certified by PricewaterhouseCoopers LLP. Such balance sheet and
         statement of income have been prepared in accordance with generally
         accepted accounting principles and fairly present the financial
         condition of the Borrower as at the close of business on the date
         thereof and the results of operations for the fiscal year then ended.
         There are no contingent liabilities of the Borrower or any of its
         Subsidiaries as of such date involving material amounts, known to the
         officers of the Borrower, which were not disclosed in such balance
         sheet and the notes related thereto and which could reasonably be
         expected to have a Material Adverse Effect.

                  7.4.3. PROJECTIONS. The projections of the annual operating
         budgets of the Borrower and its Subsidiaries on a consolidated basis,
         balance sheets and cash flow statements for the 2000 to 2001 fiscal
         years, copies of which have been delivered to each Bank, disclose all
         assumptions made with respect to general economic, financial and market
         conditions used in formulating such projections. To the knowledge of
         the Borrower or any of its Subsidiaries, no facts exist that
         (individually or in the aggregate) would result in any material change
         in any of such projections. The projections are based upon reasonable
         estimates and assumptions, have been prepared on the basis of the
         assumptions stated therein and reflect the reasonable estimates of the
         Borrower and its Subsidiaries of the results of operations and other
         information projected therein.

                  7.4.4. SOLVENCY. The Borrower and its Subsidiaries, on a
         consolidated basis, both before and after giving effect to the
         transactions contemplated by this Credit Agreement and the other Loan
         Documents (a) are solvent; (b) have assets having a fair value in
         excess of their liabilities; (c) have assets having a fair value in
         excess of the amount required to pay their liabilities on existing
         debts as such debts become due and payable, and (d) have, and expect to
         continue to have, access to adequate capital for the conduct of their
         business and the ability to pay their debts from time to time incurred
         in connection with the operation of their business as such debts
         mature.

         7.5. NO MATERIAL CHANGES, ETC. Since the Balance Sheet Date there has
occurred no materially adverse change in the financial condition or business of
the Borrower and its Subsidiaries as shown on or reflected in the consolidated
balance sheet of the Borrower and its Subsidiaries as at the Balance Sheet Date,
or the consolidated statement of income for the fiscal year then ended,



<PAGE>   43
                                      -37-


other than changes in the ordinary course of business that have not had any
Material Adverse Effect. Since the Balance Sheet Date, the Borrower has not made
any Distributions.

         7.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. Each of the Borrower and
each Guarantor possesses all franchises, patents, copyrights, trademarks, trade
names, licenses and permits, and rights in respect of the foregoing, reasonably
adequate for the conduct of its business substantially as now conducted without
known conflict with any rights of others.

         7.7. LITIGATION. Except as set forth in SCHEDULE 7.7 hereto, there are
no actions, suits, proceedings or investigations of any kind pending or
threatened against the Borrower or any of its Subsidiaries before any court,
tribunal or administrative agency or board that, if adversely determined, could
reasonably be expected, either in any case or in the aggregate, to have a
Material Adverse Effect or which question the validity of this Credit Agreement
or any of the other Loan Documents, or any action taken or to be taken pursuant
hereto or thereto.

         7.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Except as set forth on
SCHEDULE 7.8 hereto, neither the Borrower nor any of its Subsidiaries is subject
to any charter, corporate or other legal restriction, or any judgment, decree,
order, rule or regulation that has or is expected in the future to have a
Material Adverse Effect. Neither the Borrower nor any of its Subsidiaries is a
party to any contract or agreement that has or is expected, in the judgment of
the Borrower's officers, to have any Material Adverse Effect.

         7.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the Borrower
nor any Guarantor is in violation of any provision of its charter documents,
bylaws, or any agreement or instrument to which it may be subject or by which it
or any of its properties may be bound or any decree, order, judgment, statute,
license, rule or regulation, in any of the foregoing cases in a manner that
could result in the imposition of substantial penalties or have a Material
Adverse Effect.

         7.10. TAX STATUS. Except as set forth on SCHEDULE 7.10 hereto, the
Borrower and its Subsidiaries (a) have made or filed all federal and state
income and all other tax returns, reports and declarations required by any
jurisdiction to which any of them is subject, except for those filings which the
failure to so file could not reasonably be expected to have a Material Adverse
Effect and where the Borrower reasonably believes it has maintained adequate
reserves for the payment of any obligations thereunder, (b) have paid all taxes
and other governmental assessments and charges shown or determined to be due on
such returns, reports and declarations, except those being contested in good
faith and by appropriate proceedings, the non-payment of which could not
reasonably be expected to have a Material Adverse Effect and (c) have set aside
on their books provisions reasonably adequate for the payment of all taxes for
periods subsequent to the periods to which such returns, reports or declarations
apply. There are no unpaid taxes in any material amount claimed to be due by the
taxing authority of any jurisdiction, and the officers of the


<PAGE>   44
                                      -38-


Borrower know of no basis for any such claim. The Borrowing Base Report most
recently delivered to the Agent sets forth the amount of reserves established by
the Borrower and each of its Domestic Subsidiaries to, in the reasonable
judgment of the Borrower, are adequate to cover the Borrower's or such Domestic
Subsidiary's sales or use tax obligations in each jurisdiction where the
Borrower or such Domestic Subsidiary is required to pay such taxes. Such
reserves are adequate for the payment of all of such obligations.

         7.11. NO EVENT OF DEFAULT. No Default or Event of Default has occurred
and is continuing.

         7.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the Borrower
nor any of its Subsidiaries is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is it an
"investment company", or an "affiliated company" or a "principal underwriter" of
an "investment company", as such terms are defined in the Investment Company Act
of 1940.

         7.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except with respect to
Permitted Liens, there is no financing statement, security agreement, chattel
mortgage, real estate mortgage or other document filed or recorded with any
filing records, registry or other public office, that purports to cover, affect
or give notice of any present or possible future lien on, or security interest
in, any assets or property of the Borrower or any of its Subsidiaries or any
rights relating thereto.

         7.14. INSURANCE. The Borrower and each of the Guarantors maintains with
financially sound and reputable insurers insurance with respect to its
properties and businesses against such casualties and contingencies as are in
accordance with sound business practices and with the details of such coverage
being more fully described on SCHEDULE 7.14 hereto.

         7.15. CERTAIN TRANSACTIONS. Except as set forth on SCHEDULE 7.15 hereto
and except for arm's length transactions pursuant to which the Borrower or any
of its Subsidiaries makes payments in the ordinary course of business upon terms
no less favorable than the Borrower or such Subsidiary could obtain from third
parties, none of the officers, directors, or employees of the Borrower or any of
its Subsidiaries is presently a party to any transaction with the Borrower or
any of its Subsidiaries (other than for services as employees, officers and
directors), including any contract, agreement or other arrangement providing for
the furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Borrower, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

         7.16.  EMPLOYEE BENEFIT PLANS.



<PAGE>   45
                                      -39-


                  7.16.1. IN GENERAL. Each Employee Benefit Plan and each
         Guaranteed Pension Plan has been maintained and operated in compliance
         in all material respects with the provisions of ERISA and, to the
         extent applicable, the Code, including but not limited to the
         provisions thereunder respecting prohibited transactions and the
         bonding of fiduciaries and other persons handling plan funds as
         required by ss.412 of ERISA. The Borrower has heretofore delivered to
         the Agent the most recently completed annual report, Form 5500, with
         all required attachments, and actuarial statement required to be
         submitted under ss.103(d) of ERISA, with respect to each Guaranteed
         Pension Plan.

                  7.16.2. TERMINABILITY OF WELFARE PLANS. No Employee Benefit
         Plan, which is an employee welfare benefit plan within the meaning of
         ss.3(1) or ss.3(2)(B) of ERISA, provides benefit coverage subsequent to
         termination of employment, except as required by Title I, Part 6 of
         ERISA or the applicable state insurance laws. The Borrower may
         terminate each such Plan at any time (or at any time subsequent to the
         expiration of any applicable bargaining agreement) in the discretion of
         the Borrower without liability to any Person other than for claims
         arising prior to termination.

                  7.16.3. GUARANTEED PENSION PLANS. Each contribution required
         to be made to a Guaranteed Pension Plan, whether required to be made to
         avoid the incurrence of an accumulated funding deficiency, the notice
         or lien provisions of ss.302(f) of ERISA, or otherwise, has been timely
         made. No waiver of an accumulated funding deficiency or extension of
         amortization periods has been received with respect to any Guaranteed
         Pension Plan, and neither the Borrower nor any ERISA Affiliate is
         obligated to or has posted security in connection with an amendment to
         a Guaranteed Pension Plan pursuant to ss.307 of ERISA or ss.401(a)(29)
         of the Code. No liability to the PBGC (other than required insurance
         premiums, all of which have been paid) has been incurred by the
         Borrower or any ERISA Affiliate with respect to any Guaranteed Pension
         Plan and there has not been any ERISA Reportable Event (other than an
         ERISA Reportable Event as to which the requirement of 30 days notice
         has been waived), or any other event or condition which presents a
         material risk of termination of any Guaranteed Pension Plan by the
         PBGC. Based on the latest valuation of each Guaranteed Pension Plan
         (which in each case occurred within twelve months of the date of this
         representation), and on the actuarial methods and assumptions employed
         for that valuation, the aggregate benefit liabilities of all such
         Guaranteed Pension Plans within the meaning of ss.4001 of ERISA did not
         exceed the aggregate value of the assets of all such Guaranteed Pension
         Plans, disregarding for this purpose the benefit liabilities and assets
         of any Guaranteed Pension Plan with assets in excess of benefit
         liabilities.

                  7.16.4. MULTIEMPLOYER PLANS. Neither the Borrower nor any
         ERISA Affiliate has incurred any material liability (including
         secondary liability) to any Multiemployer Plan as a result of a
         complete or partial




<PAGE>   46
                                      -40-


         withdrawal from such Multiemployer Plan under ss.4201 of ERISA or as a
         result of a sale of assets described in ss.4204 of ERISA. Neither the
         Borrower nor any ERISA Affiliate has been notified that any
         Multiemployer Plan is in reorganization or insolvent under and within
         the meaning of ss.4241 or ss.4245 of ERISA or is at risk of entering
         reorganization or becoming insolvent, or that any Multiemployer Plan
         intends to terminate or has been terminated under ss.4041A of ERISA.

         7.17.  USE OF PROCEEDS.

                  7.17.1. GENERAL. The proceeds of the Revolving Credit Loans
         shall be used for working capital and general corporate purposes
         (including, without limitation, financing all or any portion of a
         Permitted Acquisition). The Borrower will obtain Letters of Credit
         solely for working capital and general corporate purposes (including,
         without limitation, financing all or any portion of a Permitted
         Acquisition).

                  7.17.2. REGULATIONS U AND X. No portion of any Revolving
         Credit Loan is to be used, and no portion of any Letter of Credit is to
         be obtained, for the purpose of purchasing or carrying any "margin
         security" or "margin stock" as such terms are used in Regulations U and
         X of the Board of Governors of the Federal Reserve System, 12 C.F.R.
         Parts 221 and 224.

         7.18. ENVIRONMENTAL COMPLIANCE. The Borrower has taken all necessary
steps to investigate the past and present condition and usage of the Real Estate
and the operations conducted thereon and, based upon such diligent
investigation, has determined that:

                  (a) none of the Borrower, its Domestic Subsidiaries or any
         operator of the Real Estate or any operations thereon is in violation,
         or alleged violation, of any judgment, decree, order, law, license,
         rule or regulation pertaining to environmental matters, including
         without limitation, those arising under the Resource Conservation and
         Recovery Act ("RCRA"), the Comprehensive Environmental Response,
         Compensation and Liability Act of 1980 as amended ("CERCLA"), the
         Superfund Amendments and Reauthorization Act of 1986 ("SARA"), the
         Federal Clean Water Act, the Federal Clean Air Act, the Toxic
         Substances Control Act, or any state or local statute, regulation,
         ordinance, order or decree relating to health, safety or the
         environment (hereinafter "Environmental Laws"), which violation could
         reasonably be expected to have a Material Adverse Effect;

                  (b) neither the Borrower nor any of its Domestic Subsidiaries
         has received notice from any third party including, without limitation,
         any federal, state or local governmental authority, (i) that any one of
         them has been identified by the United States Environmental Protection
         Agency ("EPA") as a potentially responsible party under CERCLA with
         respect to a site listed on the National Priorities List, 40 C.F.R.
         Part 300

                                      -41-


         Appendix B; (ii) that any hazardous waste, as defined by 42 U.S.C.
         ss.6903(5), any hazardous substances as defined by 42 U.S.C.
         ss.9601(14), any pollutant or contaminant as defined by 42 U.S.C.
         ss.9601(33) and any toxic substances, oil or hazardous materials or
         other chemicals or substances regulated by any Environmental Laws
         ("Hazardous Substances") which any one of them has generated,
         transported or disposed of has been found at any site at which a
         federal, state or local agency or other third party has conducted or
         has ordered that any Borrower or any of its Domestic Subsidiaries
         conduct a remedial investigation, removal or other response action
         pursuant to any Environmental Law; or (iii) that it is or shall be a
         named party to any claim, action, cause of action, complaint, or legal
         or administrative proceeding (in each case, contingent or otherwise)
         arising out of any third party's incurrence of costs, expenses, losses
         or damages of any kind whatsoever in connection with the release of
         Hazardous Substances;

                  (c) except as set forth on SCHEDULE 7.18 attached hereto: (i)
         to the Borrower's knowledge, no portion of the Real Estate has been
         used for the handling, processing, storage or disposal of Hazardous
         Substances except in accordance with applicable Environmental Laws;
         and, to the Borrower's knowledge, no underground tank or other
         underground storage receptacle for Hazardous Substances is located on
         any portion of the Real Estate; (ii) in the course of any activities
         conducted by the Borrower, its Subsidiaries or operators of its
         properties, no Hazardous Substances have been generated or are being
         used on the Real Estate except in accordance with applicable
         Environmental Laws, except where such noncompliance could not
         reasonably be expected to have a Material Adverse Effect; (iii) to the
         Borrower's knowledge, there have been no releases (i.e. any past or
         present releasing, spilling, leaking, pumping, pouring, emitting,
         emptying, discharging, injecting, escaping, disposing or dumping) or
         threatened releases of Hazardous Substances on, upon, into or from the
         properties of the Borrower or its Subsidiaries, which releases would
         have a material adverse effect on the value of any of the Real Estate
         or adjacent properties or the environment; (iv) to the Borrower's
         knowledge, there have been no releases on, upon, from or into any real
         property in the vicinity of any of the Real Estate which, through soil
         or groundwater contamination, may have come to be located on, and which
         would have a material adverse effect on the value of, the Real Estate;
         and (v) in addition, any Hazardous Substances that have been generated
         by or on behalf of the Borrower or its Subsidiaries on any of the Real
         Estate have, to the Borrower's knowledge, been transported offsite only
         by carriers having an identification number issued by the EPA, treated
         or disposed of only by treatment or disposal facilities maintaining
         valid permits as required under applicable Environmental Laws, which
         transporters and facilities have been and are, to the best of the
         Borrower's knowledge, operating in compliance with such permits and
         applicable Environmental Laws; and





<PAGE>   48
                                      -42-


                  (d) None of the Borrower and its Domestic Subsidiaries or any
         of the other Real Estate is subject to any applicable environmental law
         requiring the performance of Hazardous Substances site assessments, or
         the removal or remediation of Hazardous Substances, or the giving of
         notice to any governmental agency or the recording or delivery to other
         Persons of an environmental disclosure document or statement by virtue
         of the transactions set forth herein and contemplated hereby, or as a
         condition to the effectiveness of any other transactions contemplated
         hereby.

         7.19. SUBSIDIARIES, ETC. SCHEDULE 7.19(a) sets forth the Subsidiaries
of the Borrower. Except as set forth on SCHEDULE 7.19(b) hereto, neither the
Borrower nor any Subsidiary of the Borrower is engaged in any joint venture or
partnership with any other Person.

         7.20. CHIEF EXECUTIVE OFFICE. The Borrower's chief executive office is
at 15 Elizabeth Drive, Chelmsford, Massachusetts 01824, at which location its
books and records are kept. Each Guarantor's chief executive office is as set
forth in the Guaranty to which it is a party.

         7.21. YEAR 2000 PROBLEM. The Borrower and its Subsidiaries have (a)
reviewed the areas within their businesses and operations which could be
adversely affected by failure to become "Year 2000 Compliant" (i.e. that
computer applications, imbedded microchips and other systems used by the
Borrower or any of its Subsidiaries or any of its material vendors, will be able
properly to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999), (b) developed a
detailed plan and timetable to become Year 2000 Compliant in a timely manner,
and (c) committed adequate resources to support the Year 2000 plan of the
Borrower and its Subsidiaries. Based upon such review, the Borrower reasonably
believes that the Borrower and its Subsidiaries will become "Year 2000
Compliant" in a timely manner except to the extent that failure to do so will
not have a Material Adverse Effect.

         7.22. DISCLOSURE. None of this Credit Agreement or any of the other
Loan Documents contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements herein or
therein not misleading. There is no fact known to the Borrower or any of its
Subsidiaries which materially adversely affects, or which is reasonably likely
in the future to have a Material Adverse Effect, exclusive of effects resulting
from changes in general economic conditions, legal standards or regulatory
conditions.

         7.23. CAPITALIZATION DOCUMENTS. The Borrower and each Guarantor have
delivered to the Agent true and complete copies of all of the Capitalization
Documents and neither the Borrower nor any Guarantor has amended any such
documents in any material respects, except as may have been disclosed to and
consented to by the Agent.

                                      -43-


                    8. AFFIRMATIVE COVENANTS OF THE BORROWER.

         The Borrower covenants and agrees that, so long as any Revolving Credit
Loan, Unpaid Reimbursement Obligation, Letter of Credit or Revolving Credit Note
is outstanding or any Bank has any obligation to make any Revolving Credit Loans
or the Agent has any obligation to issue, extend or renew any Letters of Credit:

         8.1. PUNCTUAL PAYMENT. The Borrower will duly and punctually pay or
cause to be paid the principal and interest on the Revolving Credit Loans, all
Reimbursement Obligations, the Letter of Credit Fees, the commitment fees, the
Agent's fee and all other amounts provided for in this Credit Agreement and the
other Loan Documents to which the Borrower or any Guarantor is a party, all in
accordance with the terms of this Credit Agreement and such other Loan
Documents.

         8.2. MAINTENANCE OF OFFICE. The Borrower will maintain its chief
executive office in Chelmsford, Massachusetts, or at such other place in the
United States of America as the Borrower shall designate upon written notice to
the Agent, where notices, presentations and demands to or upon the Borrower in
respect of the Loan Documents to which the Borrower is a party may be given or
made.

         8.3. RECORDS AND ACCOUNTS. The Borrower will (a) keep, and cause each
of its Subsidiaries to keep, true and accurate records and books of account in
which full, true and correct entries will be made in accordance with generally
accepted accounting principles, (b) maintain in the reasonable judgment of the
Borrower adequate accounts and reserves for all taxes (including income taxes),
depreciation, depletion, obsolescence and amortization of its properties and the
properties of its Subsidiaries, contingencies, and other reserves, and (c) at
all times engage PricewaterhouseCoopers LLP or other independent certified
public accountants reasonably satisfactory to the Agent as the independent
certified public accountants of the Borrower and its Subsidiaries and will not
permit more than thirty (30) days to elapse between the cessation of such firm's
(or any successor firm's) engagement as the independent certified public
accountants of the Borrower and its Subsidiaries and the appointment in such

Agent, together with legal opinions in form and substance acceptable to the
Agent opining as to the authorization, validity and enforceability of such
Guaranty, as to due incorporation and legal existence of such Foreign Subsidiary

Subsidiary shall be considered a "Guarantor" hereunder for purposes of ss.ss.7

         include a reasonably detailed description of such Permitted
         Acquisition; (2) the business to be acquired would not subject the

         either (A) the Person so acquired is merged with and into the Borrower
         or its Subsidiary, with the Borrower or such Subsidiary, as the case
         may be, being the survivor of such merger or (B) to the extent such
         Person is not merged with and into the Borrower or a Subsidiary, such
         Person shall become a Guarantor hereunder to the extent such Person is
         a Domestic Subsidiary; (6) to the extent the aggregate Purchase Price
         (as hereinafter defined) for such Permitted Acquisition is greater than
         $7,000,000, the Borrower has demonstrated to the satisfaction of the
         Agent, based on a pro forma Compliance Certificate, compliance with
         ss.10 hereof immediately prior to and immediately after giving effect
         to such Permitted Acquisition; (7) the aggregate amount of the Purchase

         effect that (A) the Borrower and its Subsidiaries, on a consolidated
         and consolidating basis, will be solvent upon the consummation of the
         Permitted Acquisition; (B) to the extent required by (6) above, the pro
         forma Compliance Certificate fairly presents the financial condition of
         the Borrower and its Subsidiaries as of the date thereof and after
         giving


<PAGE>   61
                                      -55-


         effect to such Permitted Acquisition; and (C) no Default or Event of
         Default then exists or would result after giving effect to the
         Permitted Acquisition. For purposes of this ss.10.5.1, the Purchase
         Price shall be defined as the aggregate amount of consideration paid by
         the Borrower to the seller on the Closing Date in any Permitted
         Acquisition (including, without limitation, the aggregate amount of
         Indebtedness incurred or assumed in connection therewith regardless of
         the maturity date thereof). In addition, when valuing the capital stock
         component of the Purchase Price, the value of the Borrower's capital
         stock shall be valued in the manner consistent with the purchase
         agreement pertaining to the Permitted Acquisition, and, to the extent
         no such purchase agreement exists, or a valuation method is not
         detailed therein, then the value shall equal the average of the fair
         market value of the Borrower's capital stock for the ten (10) Business
         Days immediately preceding the date on which such Permitted Acquisition
         is consummated.

                  In the event any new Domestic Subsidiary is formed or acquired
         as a result of or in connection with any acquisition, the Loan
         Documents shall be amended and/or supplemented as necessary to make the
         terms and conditions of the Loan Documents applicable to such Domestic
         Subsidiary. Such Domestic Subsidiary shall, within thirty (30) days of
         formation, creation or acquisition, become a Guarantor hereunder and

         provided that, in each case, (i) no Default of Event of Default has

         from all such sales or dispositions does not exceed $11,500,000 in any
         fiscal year; and (iii) the Purchase Price shall be no less than the

         disposition.

lease other property that the Borrower or any Subsidiary of the Borrower intends
to use for substantially the same purpose as the property being sold or
transferred; PROVIDED, HOWEVER, notwithstanding anything to the contrary

amount of such Indebtedness or the rate of interest thereon, or making any
covenant, default or provision contained therein more onerous to the Borrower
than exists on the Closing Date. In addition, the Borrower will not amend,
supplement or otherwise modify the terms of the Subordination Agreement without
the prior written consent of the Agent.

         9.9. EMPLOYEE BENEFIT PLANS. Neither the Borrower nor any ERISA

         or ss.4068 of ERISA; or

         12.2. NO LEGAL IMPEDIMENT. No change shall have occurred in any law or
regulations thereunder or interpretations thereof that in the reasonable opinion
of any Bank would make it illegal for such Bank to make such Revolving Credit
Loan or to participate in the issuance, extension or renewal of such Letter of

         payment;

                  (b) the Borrower shall fail to pay any interest on the

         for payment;

                  (c) the Borrower shall fail to comply with any of its

         been made or repeated;

                  (f) the Borrower or any of its Subsidiaries shall fail to pay
         at maturity, or within any applicable period of grace, any obligation
         for borrowed money or credit received or in respect of any Capitalized
         Leases, in an amount in excess of $1,000,000, or fail to observe or
         perform any material term, covenant or agreement contained in any
         agreement by which it is bound, evidencing or securing borrowed money
         or credit received or in respect of any Capitalized Leases, in an
         amount in excess of $1,000,000, for such period of time as would permit
         (assuming the giving of appropriate notice if required) the holder or
         holders thereof or of any obligations issued thereunder to accelerate
         the maturity thereof, or any such holder or holders shall rescind or
         shall have a right to rescind the purchase of any such obligations;

                  (g) the Borrower or any of its Subsidiaries shall make an
         assignment for the benefit of creditors, or admit in writing its
         inability to pay or generally fail to pay its debts as they mature or
         become due, or shall petition or apply for the appointment of a trustee
         or other custodian, liquidator or receiver of the Borrower or any of
         its Subsidiaries or of any substantial part of the assets of the

         proceeding relating to the Borrower or any of its Subsidiaries under
         any bankruptcy, reorganization, arrangement, insolvency, readjustment
         of debt, dissolution or liquidation or similar law of any jurisdiction,
         now or hereafter in effect, or shall take any action to authorize or in
         furtherance of any of the foregoing, or if any such petition or
         application shall be filed or any such case or other proceeding shall
         be commenced against the Borrower or any of its Subsidiaries and the
         Borrower or any of its Subsidiaries shall indicate its approval
         thereof, consent thereto or acquiescence therein or such petition or
         application shall not have been dismissed within sixty (60) days
         following the filing thereof;

                  (h) a decree or order is entered appointing any such trustee,
         custodian, liquidator or receiver or adjudicating the Borrower or any
         of its Subsidiaries bankrupt or insolvent, or approving a petition in
         any such case or other proceeding, or a decree or order for relief is
         entered in respect of the Borrower or any Subsidiary of the Borrower in
         an involuntary case under federal bankruptcy laws as now or hereafter
         constituted;

                  (i) there shall remain in force, undischarged, unsatisfied and

<PAGE>   69
                                      -63-


                  (j) if any of the Loan Documents shall be cancelled,
         terminated, revoked or rescinded otherwise than in accordance with the
         terms thereof or with the express prior written agreement, consent or
         approval of the Banks, or any action at law, suit or in equity or other
         legal proceeding to cancel, revoke or rescind any of the Loan Documents
         shall be commenced by or on behalf of the Borrower or any of its
         Subsidiaries party thereto or any of their respective stockholders, or
         any court or any other governmental or regulatory authority or agency
         of competent jurisdiction shall make a determination that, or issue a
         judgment, order, decree or ruling to the effect that, any one or more

         accordance with the terms thereof;

                  (k) the Borrower or any ERISA Affiliate incurs any liability
         to the PBGC or a Guaranteed Pension Plan pursuant to Title IV of ERISA
         in an aggregate amount exceeding $1,000,000, or the Borrower or any
         ERISA Affiliate is assessed withdrawal liability pursuant to Title IV
         of ERISA by a Multiemployer Plan requiring aggregate annual payments
         exceeding $1,000,000, or any of the following occurs with respect to a
         Guaranteed Pension Plan: (i) an ERISA Reportable Event, or a failure to
         make a required installment or other payment (within the meaning of
         ss.302(f)(1) of ERISA), PROVIDed that the Agent determines in its
         reasonable discretion that such event (A) could be expected to result
         in liability of the Borrower or any of its Subsidiaries to the PBGC or
         such Guaranteed Pension Plan in an aggregate amount exceeding
         $1,000,000 and (B) could constitute grounds for the termination of such
         Guaranteed Pension Plan by the PBGC, for the appointment by the
         appropriate United States District Court of a trustee to administer
         such Guaranteed Pension Plan or for the imposition of a lien in favor
         of such Guaranteed Pension Plan; or (ii) the appointment by a United
         States District Court of a trustee to administer such Guaranteed
         Pension Plan; or (iii) the institution by the PBGC of proceedings to
         terminate such Guaranteed Pension Plan;

                  (l) the Borrower or any of its Subsidiaries shall be enjoined,
         restrained or in any way prevented by the order of any court or any
         administrative or regulatory agency from conducting any material part
         of its business and such order shall continue in effect for more than
         thirty (30) days;

                  (m) there shall occur any strike, lockout, labor dispute,
         embargo, condemnation, act of God or public enemy, or other casualty,
         which in any such case causes, for more than thirty (30) consecutive
         days, the cessation or substantial curtailment of revenue producing
         activities at any facility of the Borrower or any of its Subsidiaries
         if such event or circumstance is not covered by business interruption
         insurance and would have a Material Adverse Effect;

                  (n) there shall occur the loss, suspension or revocation of,
         or failure to renew, any license or permit now held or hereafter
         acquired by



<PAGE>   70
                                      -64-


         the Borrower or any of its Subsidiaries if such loss, suspension,
         revocation or failure to renew would have a Material Adverse Effect;

                  (o) the Borrower or any of its Subsidiaries shall be indicted
         for a state or federal crime, or any civil or criminal action shall
         otherwise have been brought against the Borrower or any of its
         Subsidiaries, a punishment for which in any such case could reasonably
         be expected to have a Material Adverse Effect;

                  (p) any person or group of persons (within the meaning of
         Section 13 or 14 of the Securities Exchange Act of 1934, as amended)
         shall have acquired beneficial ownership (within the meaning of Rule
         13d-3 promulgated by the Securities and Exchange Commission under said
         Act) of thirty percent (30%) or more of the outstanding shares of
         common stock of the Borrower; or, during any period of twelve
         consecutive calendar months, individuals who were directors of the
         Borrower on the first day of such period shall cease to constitute a
         majority of the board of directors of the Borrower; or

                  (q) the Borrower shall at any time, legally or beneficially
         own less than 100% of the shares of the capital stock of any Guarantor,
         PROVIDED, HOWEVER, to the extent the Borrower owns less than 100% of
         the capital stock of any Guarantor at the time such Subsidiary becomes
         a Guarantor hereunder, then it shall only constitute an Event of
         Default if the Borrower shall at any time, legally or beneficially own
         a smaller percentage of the capital stock of such Subsidiary than the
         Borrower owned on the date such Person became a Subsidiary of the
         Borrower;

then, and in any such event, so long as the same may be continuing, the Agent
may, and upon the request of the Majority Banks shall, by notice in writing to
the Borrower declare all amounts owing with respect to this Credit Agreement,
the Revolving Credit Notes and the other Loan Documents and all Reimbursement
Obligations to be, and they shall thereupon forthwith become, immediately due
and payable without presentment, demand, protest or other notice of any kind,
all of which are hereby expressly waived by the Borrower; PROVIDED that in the
event of any Event of Default specified in ss.ss.13.1(g) or 13.1(h), all such
amounts shall become immediately due and payable automatically and without any
requirement of notice from the Agent or any Bank.

         13.2. TERMINATION OF COMMITMENTS. If any one or more of the Events of
Default specified in ss.13.1(g) or ss.13.1(h) shall occur, any unused portion of
the credit hereunder shall forthwith terminate and each of the Banks shall be
relieved of all further obligations to make Revolving Credit Loans to the
Borrower and the Agent shall be relieved of all further obligations to issue,
extend or renew Letters of Credit. If any other Event of Default shall have
occurred and be continuing, the Agent may and, upon the request of the Majority
Banks, shall, by notice to the Borrower, terminate the unused portion of the
credit hereunder, and upon such notice being given such unused portion



<PAGE>   71
                                      -65-


of the credit hereunder shall terminate immediately and each of the Banks shall
be relieved of all further obligations to make Revolving Credit Loans and the
Agent shall be relieved of all further obligations to issue, extend or renew
Letters of Credit. No termination of the credit hereunder shall relieve the
Borrower or any of its Subsidiaries of any of the Obligations.

         13.3. REMEDIES. In case any one or more of the Events of Default shall
have occurred and be continuing, and whether or not the Banks shall have
accelerated the maturity of the Revolving Credit Loans pursuant to ss.13.1, each
Bank, if owed any amount with respect to the Revolving Credit Loans or the
Reimbursement Obligations, may, with the consent of the Majority Banks but not
otherwise, proceed to protect and enforce its rights by suit in equity, action
at law or other appropriate proceeding, whether for the specific performance of
any covenant or agreement contained in this Credit Agreement and the other Loan
Documents or any instrument pursuant to which the Obligations to such Bank are
evidenced, including as permitted by applicable law the obtaining of the EX
PARTE appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Bank. No remedy herein conferred upon any Bank
or the Agent or the holder of any Revolving Credit Note or purchaser of any
Letter of Credit Participation is intended to be exclusive of any other remedy
and each and every remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or any other provision of law.

                                   14. SETOFF.

         Regardless of the adequacy of any collateral, during the continuance of
any Event of Default, any deposits or other sums credited by or due from any of
the Banks to the Borrower and any securities or other property of the Borrower
in the possession of such Bank may be applied to or set off by such Bank against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank. Each of the Banks agrees with
each other Bank that (a) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by
the Revolving Credit Notes held by such Bank or constituting Reimbursement
Obligations owed to such Bank, such amount shall be applied ratably to such
other Indebtedness and to the Indebtedness evidenced by all such Revolving
Credit Notes held by such Bank or constituting Reimbursement Obligations owed to
such Bank, and (b) if such Bank shall receive from the Borrower, whether by
voluntary payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Revolving Credit Notes held by, or
constituting Reimbursement Obligations owed to, such Bank by proceedings against
the Borrower at law or in equity or by proof thereof in bankruptcy,
reorganization, liquidation, receivership or similar proceedings, or otherwise,
and shall retain and apply to the payment of the Revolving Credit Note or
Revolving Credit Notes held by, or Reimbursement Obligations owed to, such Bank
any amount in excess of its ratable portion of


<PAGE>   72
                                      -66-


the payments received by all of the Banks with respect to the Revolving Credit
Notes held by, and Reimbursement Obligations owed to, all of the Banks, such
Bank will make such disposition and arrangements with the other Banks with
respect to such excess, either by way of distribution, PRO TANTO assignment of
claims, subrogation or otherwise as shall result in each Bank receiving in
respect of the Revolving Credit Notes held by it or Reimbursement obligations
owed it, its proportionate payment as contemplated by this Credit Agreement;
PROVIDED that if all or any part of such excess payment is thereafter recovered
from such Bank, such disposition and arrangements shall be rescinded and the
amount restored to the extent of such recovery, but without interest.

                                 15. THE AGENT.

         15.1.  AUTHORIZATION.

                  (a) The Agent is authorized to take such action on behalf of
         each of the Banks and to exercise all such powers as are hereunder and
         under any of the other Loan Documents and any related documents
         delegated to the Agent, together with such powers as are reasonably
         incident thereto, PROVIDED that no duties or responsibilities not
         expressly assumed herein or therein shall be implied to have been
         assumed by the Agent.

                  (b) The relationship between the Agent and each of the Banks
         is that of an independent contractor. The use of the term "Agent" is
         for convenience only and is used to describe, as a form of convention,
         the independent contractual relationship between the Agent and each of
         the Banks. Nothing contained in this Credit Agreement nor the other
         Loan Documents shall be construed to create an agency, trust or other
         fiduciary relationship between the Agent and any of the Banks.

                  (c) As an independent contractor empowered by the Banks to
         exercise certain rights and perform certain duties and responsibilities
         hereunder and under the other Loan Documents, the Agent is nevertheless
         a "representative" of the Banks, as that term is defined in Article 1
         of the Uniform Commercial Code, for purposes of actions for the benefit
         of the Banks and the Agent with respect to all collateral security and
         guaranties contemplated by the Loan Documents. Such actions include the
         designation of the Agent as "secured party", "mortgagee" or the like on
         all financing statements and other documents and instruments, whether
         recorded or otherwise, relating to the attachment, perfection, priority
         or enforcement of any security interests, mortgages or deeds of trust
         in collateral security intended to secure the payment or performance of
         any of the Obligations, all for the benefit of the Banks and the Agent.

         15.2. EMPLOYEES AND AGENTS. The Agent may exercise its powers and
execute its duties by or through employees or agents and shall be entitled to
take, and to rely on, advice of counsel concerning all matters pertaining to its



<PAGE>   73
                                      -67-


rights and duties under this Credit Agreement and the other Loan Documents. The
Agent may utilize the services of such Persons as the Agent in its sole
discretion may reasonably determine, and all reasonable fees and expenses of any
such Persons shall be paid by the Borrower.

         15.3. NO LIABILITY. Neither the Agent nor any of its shareholders,
directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee thereof, shall be liable for any waiver,
consent or approval given or any action taken, or omitted to be taken, in good
faith by it or them hereunder or under any of the other Loan Documents, or in
connection herewith or therewith, or be responsible for the consequences of any
oversight or error of judgment whatsoever, except that the Agent or such other
Person, as the case may be, may be liable for losses due to its willful
misconduct or gross negligence.

         15.4.  NO REPRESENTATIONS.

                  15.4.1. GENERAL. The Agent shall not be responsible for the
         execution or validity or enforceability of this Credit Agreement, the
         Revolving Credit Notes, the Letters of Credit, any of the other Loan
         Documents or any instrument at any time constituting, or intended to
         constitute, collateral security for the Revolving Credit Notes, or for
         the value of any such collateral security or for the validity,
         enforceability or collectability of any such amounts owing with respect
         to the Revolving Credit Notes, or for any recitals or statements,
         warranties or representations made herein or in any of the other Loan
         Documents or in any certificate or instrument hereafter furnished to it
         by or on behalf of the Borrower or any of its Subsidiaries, or be bound
         to ascertain or inquire as to the performance or observance of any of
         the terms, conditions, covenants or agreements herein or in any
         instrument at any time constituting, or intended to constitute,
         collateral security for the Revolving Credit Notes or to inspect any of
         the properties, books or records of the Borrower or any of its
         Subsidiaries. The Agent shall not be bound to ascertain whether any
         notice, consent, waiver or request delivered to it by the Borrower or
         any holder of any of the Revolving Credit Notes shall have been duly
         authorized or is true, accurate and complete. The Agent has not made
         nor does it now make any representations or warranties, express or
         implied, nor does it assume any liability to the Banks, with respect to
         the credit worthiness or financial conditions of the Borrower or any of
         its Subsidiaries. Each Bank acknowledges that it has, independently and
         without reliance upon the Agent or any other Bank, and based upon such
         information and documents as it has deemed appropriate, made its own
         credit analysis and decision to enter into this Credit Agreement.

                  15.4.2. CLOSING DOCUMENTATION, ETC. For purposes of
         determining compliance with the conditions set forth in ss.11, each
         Bank that has executed this Credit Agreement shall be deemed to have
         consented to, approved or accepted, or to be satisfied with, each


<PAGE>   74
                                      -68-


         document and matter either sent, or made available, by the Agent to
         such Bank for consent, approval, acceptance or satisfaction, or
         required thereunder to be to be consent to or approved by or acceptable
         or satisfactory to such Bank, unless an officer of the Agent active
         upon the Borrower's account shall have received notice from such Bank
         prior to the Closing Date specifying such Bank's objection thereto and
         such objection shall not have been withdrawn by notice to the Agent to
         such effect on or prior to the Closing Date.

         15.5.  PAYMENTS.

                  15.5.1. PAYMENTS TO AGENT. A payment by the Borrower to the
         Agent hereunder or any of the other Loan Documents for the account of
         any Bank shall constitute a payment to such Bank. The Agent agrees
         promptly to distribute to each Bank such Bank's PRO RATA share of
         payments received by the Agent for the account of the Banks except as
         otherwise expressly provided herein or in any of the other Loan
         Documents.

                  15.5.2. DISTRIBUTION BY AGENT. If in the opinion of the Agent
         the distribution of any amount received by it in such capacity
         hereunder, under the Revolving Credit Notes or under any of the other
         Loan Documents might involve it in liability, it may refrain from
         making distribution until its right to make distribution shall have
         been adjudicated by a court of competent jurisdiction. If a court of
         competent jurisdiction shall adjudge that any amount received and
         distributed by the Agent is to be repaid, each Person to whom any such
         distribution shall have been made shall either repay to the Agent its
         proportionate share of the amount so adjudged to be repaid or shall pay
         over the same in such manner and to such Persons as shall be determined
         by such court.

                  15.5.3. DELINQUENT BANKS. Notwithstanding anything to the
         contrary contained in this Credit Agreement or any of the other Loan
         Documents, any Bank that fails (a) to make available to the Agent its
         PRO RATA share of any Revolving Credit Loan or to purchase any Letter
         of Credit Participation or (b) to comply with the provisions of ss.14
         with respect to making dispositions and arrangements with the other
         Banks, where such Bank's share of any payment received, whether by
         setoff or otherwise, is in excess of its PRO RATA share of such
         payments due and payable to all of the Banks, in each case as, when and
         to the full extent required by the provisions of this Credit Agreement,
         shall be deemed delinquent (a "Delinquent Bank") and shall be deemed a
         Delinquent Bank until such time as such delinquency is satisfied. A
         Delinquent Bank shall be deemed to have assigned any and all payments
         due to it from the Borrower, whether on account of outstanding
         Revolving Credit Loans, Unpaid Reimbursement Obligations, interest,
         fees or otherwise, to the remaining nondelinquent Banks for application
         to, and reduction of, their respective PRO RATA shares of all
         outstanding Revolving Credit Loans


<PAGE>   75
                                      -69-



         and Unpaid Reimbursement Obligations. The Delinquent Bank hereby
         authorizes the Agent to distribute such payments to the nondelinquent
         Banks in proportion to their respective PRO RATA shares of all
         outstanding Revolving Credit Loans and Unpaid Reimbursement
         Obligations. A Delinquent Bank shall be deemed to have satisfied in
         full a delinquency when and if, as a result of application of the
         assigned payments to all outstanding Revolving Credit Loans and Unpaid
         Reimbursement Obligations of the nondelinquent Banks, the Banks'
         respective PRO RATA shares of all outstanding Revolving Credit Loans
         and Unpaid Reimbursement Obligations have returned to those in effect
         immediately prior to such delinquency and without giving effect to the
         nonpayment causing such delinquency.

         15.6. HOLDERS OF REVOLVING CREDIT NOTES. The Agent may deem and treat
the payee of any Revolving Credit Note or the purchaser of any Letter of Credit
Participation as the absolute owner or purchaser thereof for all purposes hereof
until it shall have been furnished in writing with a different name by such
payee or by a subsequent holder, assignee or transferee.

         15.7. INDEMNITY. The Banks ratably agree hereby to indemnify and hold
harmless the Agent and its affiliates from and against any and all claims,
actions and suits (whether groundless or otherwise), losses, damages, costs,
expenses (including any expenses for which the Agent or such affiliate has not
been reimbursed by the Borrower as required by ss.17), and liabilities of every
nature and character arising out of or related to this Credit Agreement, the
Revolving Credit Notes, or any of the other Loan Documents or the transactions
contemplated or evidenced hereby or thereby, or the Agent's actions taken
hereunder or thereunder, except to the extent that any of the same shall be
directly caused by the Agent's willful misconduct or gross negligence.

         15.8. AGENT AS BANK. In its individual capacity, ABN AMRO shall have
the same obligations and the same rights, powers and privileges in respect to
its Commitment and the Revolving Credit Loans made by it, and as the holder of
any of the Revolving Credit Notes and as the purchaser of any Letter of Credit
Participations, as it would have were it not also the Agent.

         15.9. RESIGNATION. The Agent may resign at any time by giving sixty
(60) days prior written notice thereof to the Banks and the Borrower. Upon any
such resignation, the Majority Banks shall have the right to appoint a successor
Agent. Unless a Default or Event of Default shall have occurred and be
continuing, such successor Agent shall be reasonably acceptable to the Borrower.
If no successor Agent shall have been so appointed by the Majority Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be a financial institution
having a rating of not less than A or its equivalent by Standard & Poor's
Corporation. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the



<PAGE>   76
                                      -70-


retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent's resignation, the provisions of
this Credit Agreement and the other Loan Documents shall continue in effect for
its benefit in respect of any actions taken or omitted to be taken by it while
it was acting as Agent.

         15.10. NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Bank hereby
agrees that, upon learning of the existence of a Default or an Event of Default,
it shall promptly notify the Agent thereof. The Agent hereby agrees that upon
receipt of any notice under this ss.15.10 it shall promptly notify the other
Banks of the existence of such Default or Event of Default.

                        16. EXPENSES AND INDEMNIFICATION.

         16.1. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of

similar professional fees and charges) incurred by any Bank or the Agent in
connection with (i) the enforcement of or preservation of rights under any of
the Loan Documents against the Borrower or any of its Subsidiaries or the

otherwise, in any way related to any Bank's or the Agent's relationship with the

Documents or the transactions contemplated hereby including, without limitation,

proceeds of any of the Revolving Credit Loans or Letters of Credit, (b) the
Borrower or any of its Subsidiaries entering into or performing this Credit

disbursements of counsel and allocated costs of internal counsel incurred in
connection with any such investigation, litigation or other proceeding. In
litigation, or the preparation therefor, the Banks and the Agent and its
affiliates shall be entitled to select their own counsel and, in addition to the
foregoing indemnity, the Borrower agrees to pay promptly the reasonable fees and
expenses of such counsel. If, and to the extent that the obligations of the
Borrower under this ss.16.2 are unenforceable for any reason, the Borrower
hereby agrees to make the maximum contribution to the payment in satisfaction of
such obligations which is permissible under applicable law.

         16.3. SURVIVAL. The covenants contained in this ss.16 shall survive
payment or satisfaction in full of all other Obligations.

behalf of itself and each of its affiliates, directors, officers, employees and

its Subsidiaries pursuant to this Credit Agreement that is identified by such

Bank is hereby expressly permitted by the Borrower to refer to any of the
Borrower and its Subsidiaries in connection with any advertising, promotion or

required to return any materials furnished to it or any Affiliate of the Agent
or any Bank by the Borrower or any of its Subsidiaries. The obligations of each
Bank under this ss.17 shall supersede and replace the obligations of such Bank
under any confidentiality letter in respect of this financing signed and
delivered by such Bank to the Borrower prior to the date hereof and shall be
binding upon any assignee of, or purchaser of any participation in, any interest

in the Revolving Credit Notes, in any of the other Loan Documents or in any
documents or other papers delivered by or on behalf of the Borrower or any of
its Subsidiaries pursuant hereto shall be deemed to have been relied upon by the

                                      -73-


Letters of Credit, as herein contemplated, and shall continue in full force and

Borrower or any of its Subsidiaries pursuant hereto or in connection with the
transactions contemplated hereby shall constitute representations and warranties
by the Borrower or such Subsidiary hereunder.

                        19. ASSIGNMENT AND PARTICIPATION.

         19.1. CONDITIONS TO ASSIGNMENT BY BANKS. Except as provided herein,

         legal and beneficial owner of the interest being assigned thereby free
         and clear of any adverse claim, the assigning Bank makes no
         representation or warranty, express or implied, and assumes no

         sufficiency or value of this Credit Agreement, the other Loan Documents
         or any other instrument or document furnished pursuant hereto or the
         attachment, perfection or priority of any security interest or

                  (c) such assignee confirms that it has received a copy of this
         Credit Agreement, together with copies of the most recent financial
         statements referred to in ss.7.4 and ss.8.4 and such other documents
         and information as it has deemed appropriate to make its own credit
         analysis and decision to enter into such Assignment and Acceptance;

                  (d) such assignee will, independently and without reliance
         upon the assigning Bank, the Agent or any other Bank and based on such
         documents and information as it shall deem appropriate at the time,
         continue to make its own credit decisions in taking or not taking
         action under this Credit Agreement;

                  (e) such assignee represents and warrants that it is an
         Eligible Assignee;

                  (f) such assignee appoints and authorizes the Agent to take

the recordation of the names and addresses of the Banks and the Commitment
Percentage of, and principal amount of the Revolving Credit Loans owing to and

entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, the Agent and the Banks may treat each Person whose name is
recorded in the Register as a Bank hereunder for all purposes of this Credit
Agreement. The Register shall be available for inspection by the Borrower and
the Banks at any reasonable time and from time to time upon reasonable prior
notice. Upon each such recordation, the assigning Bank agrees to pay to the
Agent a registration fee in the sum of $3,500.00.

         19.4. NEW REVOLVING CREDIT NOTES. Upon its receipt of an Assignment and
Acceptance executed by the parties to such assignment, together with each
Revolving Credit Note subject to such assignment, the Agent shall (a) record the
information contained therein in the Register, and (b) give prompt notice
thereof to the Borrower and the Banks (other than the assigning Bank). Within
five (5) Business Days after receipt of such notice, the Borrower, at its own
expense, shall execute and deliver to the Agent, in exchange for each
surrendered Revolving Credit Note, a new Revolving Credit Note to the order of
such Eligible Assignee in an amount equal to the amount assumed by such Eligible
Assignee pursuant to such Assignment and Acceptance and, if the assigning Bank

aggregate principal amount equal to the aggregate principal amount of the

counsel, addressed to the Banks and the Agent, in substantially the form of the
legal opinion delivered pursuant to ss.11.10 hereof relating to the due
authorization, execution and delivery of such new Revolving Credit Notes and the
legality, validity and binding effect thereof. The surrendered Revolving Credit
Notes shall be cancelled and returned to the Borrower.

         19.5. PARTICIPATIONS. Each Bank may sell participations to one or more
banks or other entities in all or a portion of such Bank's rights and
obligations under this Credit Agreement and the other Loan Documents; PROVIDED
that (a) each such participation shall be in an amount of not less than
$1,000,000.00, (b) any such sale or participation shall not affect the rights

<PAGE>   82
                                      -76-


selling Bank hereunder to the Borrower and (c) the only rights granted to the
participant pursuant to such participation arrangements with respect to waivers,
amendments or modifications of the Loan Documents shall be the rights to approve
waivers, amendments or modifications that would reduce the principal of or the
interest rate on any Revolving Credit Loans, extend the term or increase the
amount of the Commitment of such Bank as it relates to such participant, reduce

participant is entitled or extend any regularly scheduled payment date for
principal or interest.

         19.6. DISCLOSURE. The Borrower agrees that in addition to disclosures
made in accordance with standard and customary banking practices any Bank may
disclose information obtained by such Bank pursuant to this Credit Agreement to
assignees or participants and potential assignees or participants hereunder;
PROVIDED that such assignees or participants or potential assignees or
participants shall agree (a) to treat in confidence such information unless such
information otherwise becomes public knowledge, (b) not to disclose such
information to a third party, except as required by law or legal process and (c)
not to make use of such information for purposes of transactions unrelated to
such contemplated assignment or participation. For purposes of this ss.19.6 an
assignee or participant or potential assignee or participant may include a
counterparty with whom such Bank has entered into or potentially might enter
into a Derivative Contract referenced to credit or other risks or events arising
under this Credit Agreement or any other Loan Document.

         19.7. ASSIGNEE OR PARTICIPANT AFFILIATED WITH THE BORROWER. If any
assignee Bank is an Affiliate of the Borrower, then any such assignee Bank shall
have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Agent pursuant to ss.13.1 or ss.13.2, and
the determination of the Majority Banks shall for all purposes of this Credit
Agreement and the other Loan Documents be made without regard to such assignee
Bank's interest in any of the Revolving Credit Loans or Reimbursement
Obligations. If any Bank sells a participating interest in any of the Revolving
Credit Loans or Reimbursement Obligations to a participant, and such participant
is the Borrower or an Affiliate of the Borrower, then such transferor Bank shall
promptly notify the Agent of the sale of such participation. A transferor Bank
shall have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or modifications to any of the Loan Documents or for
purposes of making requests to the Agent pursuant to ss.13.1 or ss.13.2 to the
extent that such participation is beneficially owned by the Borrower or any
Affiliate of the Borrower, and the determination of the Majority Banks shall for
all purposes of this Credit Agreement and the other Loan Documents be made
without regard to the interest of such transferor Bank in the Revolving Credit
Loans or Reimbursement Obligations to the extent of such participation.

         19.8. MISCELLANEOUS ASSIGNMENT PROVISIONS. Any assigning Bank shall
retain its rights to be indemnified pursuant to ss.16 with respect to any claims
or actions arising prior to the date of such assignment. If any assignee Bank is
not incorporated under the laws of the United States of America or any state
thereof, it shall, prior to the date on which any interest or fees are payable
hereunder or under any of the other Loan Documents for its account, deliver to

                              REVOLVING CREDIT NOTE

$30,000,000                                               as of January 7, 2000


         FOR VALUE RECEIVED, the undersigned BROOKS AUTOMATION, INC., a Delaware
corporation (the "Borrower"), hereby promises to pay to the order of ABN AMRO
BANK N.V., (the "Bank") at the Agent's Head Office (as such term is defined in
the Credit Agreement referred to below):

                  (a) prior to or on the Revolving Credit Loan Maturity Date the
         principal amount of THIRTY MILLION DOLLARS ($30,000,000) or, if less,
         the aggregate unpaid principal amount of Revolving Credit Loans
         advanced by the Bank to the Borrower pursuant to the Revolving Credit
         Agreement dated as of January 7, 2000 (as amended and in effect from
         time to time, the "Credit Agreement"), among the Borrower, the Bank and
         other parties thereto;

                  (b) the principal outstanding hereunder from time to time at
         the times provided in the Credit Agreement; and

                  (c) interest on the principal balance hereof from time to time
         outstanding from the Closing Date under the Credit Agreement through
         and including the maturity date hereof at the times and at the rate
         provided in the Credit Agreement.

         This Note evidences borrowings under and has been issued by the
Borrower in accordance with the terms of the Credit Agreement. The Bank and any
holder hereof is entitled to the benefits of the Credit Agreement, the Guaranty
and the other Loan Documents, and may enforce the agreements of the Borrower
contained therein, and any holder hereof may exercise the respective remedies
provided for thereby or otherwise available in respect thereof, all in
accordance with the respective terms thereof. All capitalized terms used in this
Note and not otherwise defined herein shall have the same meanings herein as in
the Credit Agreement.

         The Borrower irrevocably authorizes the Bank to make or cause to be
made, at or about the time of the Drawdown Date of any Revolving Credit Loan or
at the time of receipt of any payment of principal of this Note, an appropriate
notation on the grid attached to this Note, or the continuation of such grid, or
any other similar record, including computer records, reflecting the making of
such Revolving Credit Loan or (as the case may be) the receipt of such payment.
The outstanding amount of the Revolving Credit Loans set forth on the grid
attached to this Note, or the continuation of such grid, or any other similar
record, including computer records, maintained by the Bank with respect to any
Revolving Credit Loans shall be PRIMA FACIE evidence of the principal




<PAGE>   2
                                      -2-


amount thereof owing and unpaid to the Bank, but the failure to record, or any
error in so recording, any such amount on any such grid, continuation or other
record shall not limit or otherwise affect the obligation of the Borrower
hereunder or under the Credit Agreement to make payments of principal of and
interest on this Note when due.

         The Borrower has the right in certain circumstances and the obligation
under certain other circumstances to prepay the whole or part of the principal
of this Note on the terms and conditions specified in the Credit Agreement.

         If any one or more of the Events of Default shall occur, the entire
unpaid principal amount of this Note and all of the unpaid interest accrued
thereon may become or be declared due and payable in the manner and with the
effect provided in the Credit Agreement.

         No delay or omission on the part of the Bank or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Bank or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any further occasion.

         The Borrower and every endorser and guarantor of this Note or the
obligation represented hereby waives presentment, demand, notice, protest and
all other demands and notices in connection with the delivery, acceptance,
performance, default or enforcement of this Note, and assents to any extension
or postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of collateral and to the addition or release
of any other party or person primarily or secondarily liable.

         THIS NOTE AND THE OBLIGATIONS OF THE BORROWER HEREUNDER SHALL FOR ALL
PURPOSES BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
COMMONWEALTH OF MASSACHUSETTS (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR
CHOICE OF LAW). THE BORROWER AGREES THAT ANY SUIT FOR THE ENFORCEMENT OF THIS
NOTE MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY
FEDERAL COURT SITTING THEREIN AND THE CONSENT TO THE NONEXCLUSIVE JURISDICTION
OF SUCH COURT AND THE SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON THE
BORROWER BY MAIL AT THE ADDRESS SPECIFIED IN SS.20 OF THE CREDIT AGREEMENT. THE
BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE
VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN
INCONVENIENT COURT.

         This Note shall be deemed to take effect as a sealed instrument under
the laws of the Commonwealth of Massachusetts.

         IN WITNESS WHEREOF, the undersigned has caused this Revolving Credit
Note to be signed in its corporate name and its corporate seal to be

                                   LEASE


      THIS LEASE AGREEMENT (this "LEASE") is entered into as of January 31,
2000, between W9/TIB REAL ESTATE LIMITED PARTNERSHIP, a Delaware limited
partnership ("LANDLORD"), and BROOKS AUTOMATION, INC., a Delaware corporation
("TENANT").

      1. DEFINITIONS AND BASIC PROVISIONS. The definitions and basic provisions
set forth in the Basic Lease Information (the "BASIC LEASE INFORMATION")
executed by Landlord and Tenant contemporaneously herewith are incorporated
herein by reference for all purposes. Additionally, the following terms shall
have the following meanings when used in this Lease: "LAWS" means all federal,
state, and local laws, rules and regulations, all court orders, governmental
directives, and governmental orders, and all restrictive covenants affecting the
Property, and "LAW" shall mean any of the foregoing; "AFFILIATE" means any
person or entity which, directly or indirectly, through one or more
intermediaries, controls, is controlled by, or is under common control with the
party in question; "TENANT PARTY" means any of the following persons: Tenant;
any assignees claiming by, through, or under Tenant; any subtenants claiming by,
through, or under Tenant; and any of their respective agents, contractors,
employees, and invitees; and "INCLUDING" means including, without limitation.

      2. LEASE GRANT. Subject to the terms of this Lease, Landlord leases to
Tenant, and Tenant leases from Landlord, the Premises.

      3. TERM. By occupying the Premises, Tenant shall be deemed to have
accepted the Premises in their condition as of the date of such occupancy.
Tenant shall execute and deliver to Landlord, within ten days after Landlord has
requested the same, an amendment substantially in the form of Exhibit E hereto
confirming the Commencement Date and the expiration date of the initial Term,
that Tenant has accepted the Premises, and that Landlord has performed all of
its obligations with respect to the Premises.

      4. RENT.

            (a) PAYMENT. Tenant shall timely pay to Landlord Basic Rent and all
additional sums to be paid by Tenant to Landlord under this Lease, without
notice, deduction or set off, except as otherwise expressly set forth herein, at
Landlord's address provided for in this Lease or as otherwise specified by
Landlord and shall be accompanied by all applicable state and local sales or use
taxes. Basic Rent, adjusted as herein provided, shall be payable monthly in
advance. The first monthly installment of Basic Rent shall be payable
contemporaneously with the execution of this Lease; thereafter, Basic Rent shall
be payable on the first day of each month beginning on the first day of the
second 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
<PAGE>   10
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.

            (b)   OPERATING COSTS; TAXES; ELECTRICAL COSTS.

                  (1) Tenant shall pay all of the Operating Costs (defined
below) ("ADDITIONAL RENT"). 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 than twice in any Lease Year),
Landlord may estimate and re-estimate the Additional Rent to be due by Tenant
and deliver a copy of the estimate or re-estimate to Tenant, which estimate
shall itemize each increased cost. 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 sound accounting principles consistently applied,
including, but not limited to, the following costs: (A) wages and salaries
(management fees, which management fees shall not exceed fair market management
fees for comparable buildings in the Greater Boston area) of all employees
engaged in the operation, maintenance, and security of the Premises, including
taxes, insurance and benefits relating thereto; (B) all supplies and materials
used in the operation, maintenance, repair, replacement, and security of the
Premises; (C) costs for improvements made to the Premises which, although
capital in nature, are expected to reduce the normal operating costs (including
all utility costs) of the Premises, as well as capital improvements made in
order to comply with any law hereafter promulgated by any governmental authority
and capital improvements related to roof replacement and replacement of rooftop
HVAC units, as 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 reimbursable to Landlord by Tenant other than
pursuant to a provision similar to this Section 4.(b); (E) insurance expenses;
(F) repairs, replacements, and general maintenance of the Premises; (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);
and (H) accounting fees incurred by Landlord for the accounting services
performed in connection with the Premises.

                  Operating Costs shall not include costs for (i) capital
improvements made to the Premises, other than capital improvements described in
Section 4.(b)(2)(C) and except for items which are generally considered
maintenance and
<PAGE>   11
repair items, such as painting of common areas, replacement of carpet in
elevator lobbies, and the like; (ii) repair, replacements and general
maintenance paid by proceeds of insurance or by Tenant or other third parties;
(iii) interest, amortization or other payments on loans to Landlord or any
ground lease rent; (iv) depreciation; (v) leasing commissions; (vi) legal
expenses for services, other than those that benefit the Building tenants
generally (e.g., tax disputes); (vii) Taxes (defined below); (viii) franchise or
federal income taxes imposed on or measured by the income of Landlord from the
operation of the Building; (ix) any cost or expense to the extent to which
Landlord is paid or reimbursed (other than as a payment for Operating Costs);
(x) salaries and bonuses of officers and executives of Landlord; (xi) any fees,
costs, and commissions incurred in procuring or attempting to procure tenants
including, but not necessarily limited to brokerage commissions, finders fees,
attorney's fees and expenses, entertainment costs and travel expenses; (xii) the
cost of advertising or promotion for the Building; (xiii) reserves; (xiv)
Landlord's charitable or political contributions; (xv) Landlord's travel or
entertainment expenses; (xvi) depreciation of the Building; and (xvii) provided
Tenant is not in default of any provisions of this Lease beyond all applicable
notice and cure periods, fines or penalties arising solely out of Landlord's
breach of any obligation hereunder.

                  (3) Tenant shall also pay all of 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 Premises (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 Premises, 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). 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 Premises. For property tax
purposes, Tenant waives all rights to protest or appeal the appraised value of
the Premises, as well as the Building, and all rights to receive notices of
reappraisement. Taxes shall be deemed payable over the longest period allowed by
law. Tenant may file for and prosecute tax abatements pertaining to the Premises
only after it has notified Landlord that Tenant desires Landlord pursue a tax
abatement and Landlord elects not to pursue such a tax abatement and so notifies
Tenant in writing. If Tenant files for and prosecutes a tax abatement pertaining
to the Premises, Tenant shall simultaneously provide Landlord with all filings
made with the taxing authorities and with any other information reasonably
requested by Landlord.

                  (4)   Intentionally Omitted.
<PAGE>   12
                  (5) By April 1 of each calendar year, or as soon thereafter as
reasonably practicable, Landlord shall furnish to Tenant a statement of
Operating Costs for the previous year, 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 Tenant's
actual Additional Rent or Taxes due, then Tenant shall promptly pay Landlord
such deficiency.

                  (6) Provided (A) Tenant is not in default hereunder, and (B)
Tenant has paid Landlord the Operating Costs in question, Tenant shall have the
right, exercisable not more than once each Lease Year, to examine Landlord's
books and records relating to Operating Costs for the prior Lease Year only.
Such examination shall be performed (i) at Landlord's office, (ii) at Tenant's
sole cost and expense, (iii) upon prior reasonable written notice to Landlord,
(iv) during normal business hours, and (v) within sixty (60) days after receipt
of the Operating Costs and Tax Statement. In the event Tenant's examination
reveals a discrepancy, Landlord shall promptly (but no later than thirty (30)
days) reimburse Tenant for the amount of any overpayment. If Tenant's
examination of Landlord's books and records reveals an overcharge of more than
five percent (5%), Landlord shall, within thirty (30) days after receipt of a
written invoice, reimburse Tenant for the reasonable costs of such audit. In
conducting such audit, Tenant shall use an independent certified public
accountant experienced in auditing Operating Costs, which accountant shall be
paid on an hourly basis (and not on a contingency or success fee basis). Such
audit shall be conducted in accordance with generally accepted rules of auditing
practices. Any information obtained by Tenant pursuant to the provisions of this
Section 3(b)(6) shall be treated as confidential.

            (c) BILLING FOR ELECTRICITY. Tenant shall pay (as hereinafter
described) for the use of all electrical service to the Premises. Tenant shall
be billed directly by such utility company and Tenant agrees to pay each bill
promptly in accordance with its terms, and upon default in making any such
payment which continues for more than ten (10) days after written notice to
Tenant, Landlord may pay such charges and collect the same from Tenant. In the
event for any reason Tenant cannot be billed directly, Landlord shall forward
each bill received with respect to the Building to Tenant, which Tenant shall
pay within thirty (30) days of receiving each such bill unless the terms of the
each such bill specify otherwise.

      5. DELINQUENT PAYMENT; HANDLING CHARGES. All past due payments required of
Tenant hereunder shall bear interest from the date due until paid at the lesser
of fifteen percent per annum or the maximum lawful rate of interest;
additionally, if Tenant fails to make any payment due hereunder more than once
in any Lease Year, Landlord may charge Tenant a fee equal to 5% of the
delinquent payment to reimburse Landlord for its cost and inconvenience incurred
as a consequence of Tenant's delinquency. In no event, however, shall the
charges permitted under this Section 5 or
<PAGE>   13
elsewhere in this Lease, to the extent they are considered to be interest under
applicable Law, exceed the maximum lawful rate of interest.

      6. SECURITY DEPOSIT. Contemporaneously with the execution of this Lease,
Tenant shall pay to Landlord the Security Deposit, which Security Deposit shall
be the same Security Deposit held under this Lease and under the 16 Elizabeth
Drive Lease (as hereinafter defined in Section 17(b)) and shall be held by
Landlord to secure Tenant's performance of its obligations under this Lease and
under the 16 Elizabeth Drive Lease. If, for whatever reason, either this Lease
or the 16 Elizabeth Drive Lease terminates prior to the stated expiration date
and/or the Term of only one of said Leases is extended and no further
obligations are due and owing under the expired and/or terminated Lease, the
Security Deposit shall continue to secure Tenant's obligations under the
applicable Lease which has not expired and/or terminated. 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 17). Landlord may, from time to
time following an Event of Default 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 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 or
return same to Tenant and Landlord thereafter shall have no further liability
for the return of the Security Deposit.

      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 $1,000,000.00 (the "LETTER OF CREDIT"), in the form
of the sample letter of credit attached hereto as Exhibit I 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
<PAGE>   14
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 upon the earlier of (x) the expiration of said
sixty-day period or (y) at least forty-five (45) 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 6); 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.

      Notwithstanding any of the foregoing provisions of this Section 6 to the
contrary, if Tenant has a Tangible Net Worth of at least $165,000,000.00 on the
eighteenth (18th) month after the Commencement Date (the "REDUCTION DATE"), the
Security Deposit (or the applicable Letter or Credit) shall be reduced by
$500,000.00, provided that on the Reduction Date (i) the Lease is in full force
and effect, (ii) no Event of Default exists, (iii) no Event of Default has
occurred, and (iv) Tenant has not assigned this Lease to anyone other than a
Permitted Transferee. If on the Reduction Date the Security Deposit (or the
applicable Letter of Credit) shall not be reduced because one or more of the
conditions set forth in clauses (i), (ii) or (iii) above cease to exist on the
Reduction Date, the Security Deposit (or applicable Letter of Credit) shall not
be reduced during any succeeding calendar year. If on the Reduction Date the
Security Deposit (or applicable Letter of Credit) shall not be reduced because
only the condition set forth in clause (iv) above (as opposed to the conditions
set forth in any of clauses (i), (ii) or (iii) above) ceases to exist on the
Reduction Date and/or Tenant does not have a Tangible Net Worth of at least
$165,000,000.00 on the Reduction Date, the Security Deposit (or applicable
Letter of
<PAGE>   15
Credit) shall be so reduced on the date that Tenant has achieved a Tangible Net
Worth of $165,000,000.00, provided the conditions set forth in clauses (i),
(ii), (iii) and (iv) above exist on such date. If the Security Deposit (or
applicable Letter of Credit) is reduced pursuant to the foregoing provisions,
Landlord shall return the amount of the reduction if Tenant paid the Security
Deposit in cash or Tenant may replace and/or amend the Letter of Credit
accordingly.

      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 6, 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.

      7.    LANDLORD'S OBLIGATIONS

            (a) SERVICES. Landlord shall furnish to Tenant the following
services (the cost of which services shall be considered Operating Costs): (1)
water at those points of supply to the Building as currently exist; (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 holidays, for Building-standard installations and such
window washing as may from time to time be reasonably required; (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 if any person(s) other than Tenant or any assignees or sublessees of
Tenant permitted hereunder occupies any portion of the Premises; and (5)
electrical current 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 7.(a) with reputable, licensed (if applicable) 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
<PAGE>   16
preceding sentence, Tenant engages (at its own cost) providers for all of the
services to be provided by Landlord under this Section 7.(a), the management fee
included in Operating Costs shall be reduced to the greater of (i) $1,800.00 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 7.(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 at least
twenty (20) days prior written notice to Tenant (except in the event of an
emergency or in situations where Landlord's prompt action is necessary to
prevent damage or deterioration to any portion of the Premises, in which case no
advance notice shall be required), elect to provide such services and the
management fee shall no longer be reduced; provided, however, to the extent the
twenty-day grace period exists, Landlord's election shall be deemed null and
void and of no further force and effect if Tenant causes the services being
performed at an unsatisfactory level to be performed at a satisfactory level
within the twenty-day period.

      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 7.(a). If Tenant is engaging providers of such services in
accordance with the provisions of this Lease, Landlord may perform periodic
inspections of the Building and all such inspection costs shall be considered an
Operating Cost and paid by Tenant in accordance with Section 4 above. However,
upon sixty (60) days prior written notice to Landlord, Tenant may elect to have
Landlord provide such services.

            (b) LANDLORD'S MAINTENANCE OBLIGATIONS. This Lease is intended to be
a net lease; accordingly, Landlord's maintenance obligations (other than those
set forth in Section 7(a), if applicable) 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, maintenance and/or replacement of the
roof, which repair, maintenance and/or replacement costs shall be considered an
Operating Cost and paid by Tenant in accordance with Section 4 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. Notwithstanding any
provisions of this Lease to the contrary, Landlord may replace the roof and the
roof membrane at any time, but shall be required to replace the roof and the
roof membrane if the cost to repair the roof and the roof membrane over an
aggregate twelve-month period exceeds $30,000.00 provided that such repair work
is not necessitated by either a catastrophic failure caused by severe weather
events or any act or omission by or on behalf of any Tenant Party.
<PAGE>   17
            (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 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 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 Building
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, or entail excessive or unreasonable
alterations, repairs, or expenses. 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 more than fifteen (15)
consecutive business days because of the unavailability of any such service and
such unavailability was not caused by a Tenant Party, then Tenant shall, as its
exclusive remedy be entitled to a reasonable abatement of Rent for each
consecutive day (after such 15-day period) that Tenant is so prevented from
using the Premises.

            (e) LANDLORD'S COMPLIANCE WITH APPLICABLE LEGAL REQUIREMENTS.
Landlord shall comply with all legal requirements directly applicable to the
structural elements of the Building; but only to the extent that a failure to so
comply shall materially affect the Building, Tenant's use thereof or Tenant's
access thereto or results in Tenant being held responsible for the violation.
Landlord may contest in good faith the validity or application of any legal
requirements with which Landlord may be obligated to comply. Notwithstanding the
foregoing, all expenses incurred by Landlord to comply with all such legal
requirements enacted after the date of this Lease shall be considered an
Operating Cost and paid by Tenant in accordance with Section 4 above.

      8.    IMPROVEMENTS; ALTERATIONS; REPAIRS; MAINTENANCE.

            (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 Building,
without the consent of Landlord and without Landlord's approval of plans,
provided: (i) the cost thereof shall not exceed Twenty-Five Thousand Dollars
($25,000.00) in the aggregate in any consecutive twelve-month period; (ii)
Tenant shall, prior to commencing any such alterations, additions and/or
improvements in the Building 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 or plumbing systems of the Building or the base building
electrical system, as such base building electrical system exists after Tenant's
installation of the Work (but such alterations may include minor electrical
alterations not affecting the base building electrical system); 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 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. Notwithstanding
any provisions of the preceding sentence to the contrary, if Tenant is the sole
occupant of the Building, Landlord's prior written consent shall only be
required with respect to the painting or installation of lighting or
decorations, signs, window or door lettering, or advertising media of any type
on or about the Premises which would affect the exterior of the Building. 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. Landlord shall cooperate with Tenant in obtaining any permits or licenses
sought by Tenant in connection with the Premises provided Landlord shall never
be required to pay any out-of-pocket expenses in connection therewith.

            (b) REPAIRS; MAINTENANCE. Tenant shall maintain the Premises in a
clean, safe, and operable condition as exists after the construction of the Work
(as hereinafter defined) and any other alterations, additions or improvements
performed by Tenant, reasonable wear and tear and damage by fire, other casualty
and eminent domain excepted, consistent with the operation of a first class
building consistent with the
<PAGE>   19
Permitted Use, 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 7.(a) above, Tenant shall enter into
preventative maintenance/service contract(s) with maintenance contractor(s)
reasonably 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. Upon request from Landlord, Tenant shall provide Landlord
with copies of all such preventative maintenance/service contracts maintained by
Tenant. Irrespective of whether or not Tenant elects to engage providers for all
services in accordance with Section 7.(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 fifteen
(15) 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, after written notice to Tenant, make the same at Tenant's cost.
Notwithstanding any provisions of this Lease to the contrary, if the cost to
repair one of the existing rooftop HVAC units exceeds twenty-five percent (25%)
of the replacement cost for such unit, Landlord shall pay for such replacement
cost within twenty (20) business days after satisfaction of the following terms
and conditions: (i) Landlord and Tenant agree in writing on any such replacement
cost, on the specification of the new rooftop unit, and on the contractor to
install such new unit; (ii) Tenant shall ensure such new unit is installed in
accordance with applicable Laws; (iii) Tenant shall not be in default under this
Lease; (iv) this Lease shall be in full force and effect; (v) Tenant has
provided Landlord with evidence reasonably satisfactory to Landlord that the new
unit has been installed in accordance with applicable Laws; (vi) Tenant has
maintained and repaired such unit in accordance with the provisions of this
Lease; and (vii) such replacement costs shall be considered an Operating Cost
and paid by Tenant in accordance with Section 4 above.

            (c) PERFORMANCE OF WORK. All work described in this Section 8 shall
be performed only by Landlord or by contractors and subcontractors reasonably
approved in writing by Landlord. 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 Building (including the Premises, the structural elements, and the
plumbing, electrical lines, or other utility transmission facility). All such
work which may affect the Building's HVAC, electrical, plumbing, other
mechanical systems, or structural elements must be approved by the Building's
engineer of record, at Tenant's expense and, at Landlord's election, must be
performed by Landlord's usual contractor for such work, unless otherwise
approved by Landlord.
<PAGE>   20
      Tenant shall provide sworn statements, including the names, addresses and
copies of contracts for all contractors, and upon completion of any work shall
promptly furnish Landlord with sworn owner's and contractor's statements and
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 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. 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 heavy 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, not to be unreasonably
withheld, conditioned or delayed, which consent may include a requirement to
provide insurance, naming Landlord as an insured, in such amounts as Landlord
may deem reasonable.

                  (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.

      9. USE. Tenant shall occupy and use the Premises only for the Permitted
Use, and for no other purposes, and shall comply with all Laws relating to the
use, condition, access to, and occupancy of the Premises. The population density
within the Premises as a whole shall at no time exceed one person for each 200
rentable square feet
<PAGE>   21
in 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 Building or its contents, or for the storage of any
Hazardous Materials. If, because of a Tenant Party's acts, the rate of insurance
on the Building or its contents increases, then 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. If Tenant fails to cease or remediate such
acts within five (5) days after Landlord's request that Tenant do so, then such
acts shall be an Event of Default. Tenant shall conduct its business and control
each other Tenant Party so as not to create any nuisance or unreasonably
interfere with other tenants or Landlord in its management of the Building.

         10. ASSIGNMENT AND SUBLETTING

            (a) TRANSFERS. Except as provided in Section 10.(g), 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 10.(a)(1) through 10.(a)(6) being a "TRANSFER").

            (b) CONSENT STANDARDS. Landlord shall not unreasonably withhold,
condition or delay its consent to any assignment or subletting of the Premises,
provided that the proposed transferee is creditworthy, has a good reputation in
the business community, will use the Premises for the Permitted Use (thus,
excluding, without limitation, uses for credit processing and telemarketing) and
will not use the Premises in any manner that would conflict with any exclusive
use agreement or other similar agreement entered into by Landlord with any other
tenant of the Building, is not a governmental entity, or subdivision or agency
thereof, and is not another occupant of the Building or person or entity with
whom Landlord is negotiating to lease space in the Building; otherwise, Landlord
may withhold its consent in its sole discretion.

            (c) REQUEST FOR CONSENT. 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. Landlord shall approve such request,
or indicate its basis for refusing consent, within thirty (30) days after
receipt of such request and receipt of all of the information enumerated in the
preceding sentence. Concurrently with Tenant's notice of any request for consent
to a Transfer, Tenant shall pay to Landlord a fee of $750 to defray Landlord's
expenses in reviewing such request, and Tenant shall also reimburse Landlord
<PAGE>   22
immediately upon request for its reasonable attorneys' fees incurred in
connection with considering any request for consent to a Transfer.

            (d) CONDITIONS TO CONSENT. 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.

            (e) CANCELLATION. Landlord may, within 30 days after submission of
Tenant's written request for Landlord's consent to an assignment or subletting,
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. If Landlord
cancels this Lease as to any portion of the Premises, 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.

            (f) ADDITIONAL COMPENSATION. Tenant shall pay to Landlord,
immediately upon receipt thereof, seventy-five percent (75%) of 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.

            (g) PERMITTED TRANSFERS. Notwithstanding Section 10.(a), Tenant may
Transfer all or part of its interest in this Lease or all or part of the
Premises (a "PERMITTED TRANSFER") to the following types of entities (a
"PERMITTED TRANSFEREE") without the written consent of Landlord:

                  (1)   an Affiliate of Tenant;

                  (2) any corporation, limited partnership, limited liability
      partnership, limited liability company or other business entity in which
      or with which Tenant, or its corporate successors or assigns, is merged or
      consolidated, in accordance with applicable statutory provisions governing
      merger and
<PAGE>   23
          consolidation of business entities, so long as (A) Tenant's
          obligations hereunder are assumed by the entity surviving such merger
          or created by such consolidation; and (B) the Tangible Net Worth of
          the surviving or created entity is not less than the greater of (i)
          the Tangible Net Worth of Tenant as of the date hereof, or (ii) the
          Tangible Net Worth of Tenant at the time of any such Permitted
          Transfer; or

               (3) any corporation, limited partnership, limited liability
          partnership, limited liability company or other business entity
          acquiring all or substantially all of Tenant's assets if such entity's
          Tangible Net Worth after such acquisition is not less than the greater
          of (i) the Tangible Net Worth of Tenant as of the date hereof, or (ii)
          the Tangible Net Worth of Tenant at the time of any such Permitted
          Transfer.

      Tenant shall promptly notify Landlord of any such Permitted Transfer.
Tenant shall remain liable for the performance of all of the obligations of
Tenant hereunder, or if Tenant no longer exists because of a merger,
consolidation, or acquisition, the surviving or acquiring entity shall expressly
assume in writing the obligations of Tenant hereunder. Additionally, the
Permitted Transferee shall comply with all of the terms and conditions of this
Lease, including the Permitted Use, and the use of the Premises by the Permitted
Transferee may not violate any other agreements affecting the Premises, the
Building, Landlord or other tenants of the Building. At least 30 days after the
effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with
copies of the instrument effecting any of the foregoing Transfers and
documentation establishing Tenant's satisfaction of the requirements set forth
above applicable to any such Transfer. The occurrence of a Permitted Transfer
shall not waive Landlord's rights as to any subsequent Transfers. "TANGIBLE NET
WORTH" means the excess of total assets over total liabilities, in each case as
determined in accordance with generally accepted accounting principles
consistently applied ("GAAP"), excluding, however, from the determination of
total assets all assets which would be classified as intangible assets under
GAAP including, without limitation, goodwill, licenses, patents, trademarks,
trade names, copyrights, and franchises. Any subsequent Transfer by a Permitted
Transferee shall be subject to Landlord's prior written consent (which Landlord
may grant or deny in its sole discretion).

      11.   INSURANCE; WAIVERS; SUBROGATION; INDEMNITY

            (a) TENANT'S INSURANCE. Tenant shall maintain throughout the Term
the following insurance policies: (1) commercial general liability insurance in
amounts of $3,000,000 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 (but only if such contractual liability insurance is not
already included in Tenant's commercial general liability insurance policy), (4)
worker's
<PAGE>   24
compensation insurance, containing a waiver of subrogation endorsement
acceptable to Landlord, 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 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) LANDLORD'S INSURANCE. Landlord shall carry throughout the Term
of this Lease fire and extended coverage insurance on the Building for at least
90% of the full replacement value.

            (c) 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 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.

            (d) INDEMNITY. Subject to Section 11.(c), 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 during the Term or any
holdover by Tenant or any person or entity deriving rights from Tenant beyond
the expiration of the Term (other than any Loss arising out of a breach of
Tenant's obligations under Section 25.(t), which shall be subject to the
indemnity in such section) except to the extent caused by the negligence or
fault of Landlord or its agents or (2) Tenant's failure to perform its
obligations under this Lease except to the extent caused 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
reasonably satisfactory to the indemnified party.

      12.   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
<PAGE>   25
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. Provided
Tenant receives a Non-Disturbance Agreement from each such Mortgagee, 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. Provided Tenant receives a Non-Disturbance Agreement
from such party, 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.

            (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 unless such rent is actually received by
Landlord's Mortgagee; (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 Building 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
Building. Nothing in this Lease shall be construed to require Landlord's
Mortgagee to see to the application of the proceeds of
<PAGE>   26
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, executed by Landlord and the Lender named therein to Tenant as soon as
reasonably possible. Landlord shall use reasonable efforts (which efforts shall
not require the expenditure of funds or the threat (or commencement) of
litigation) to obtain a so-called "nondisturbance agreement" from any future
Landlord's Mortgagee in the form attached hereto as Exhibit J or another form
reasonably acceptable to Tenant and such Landlord's Mortgagee or other
institutional lenders (either the form attached hereto as Exhibit J or such
other reasonably acceptable form being herein referred to as the
"NON-DISTURBANCE AGREEMENT"). The subordination of Tenant's rights hereunder to
any future Landlord's Mortgagee under Section 12.(a) and the attornment of
Tenant to any future Landlord Mortgagee under Section 12.(b) shall be
conditioned upon such future Landlord's Mortgagee's execution and delivery of a
Non-Disturbance Agreement.

      13. 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 are applicable to all tenants of the Building and 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.

      14.   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 180 days, then Tenant
may terminate this Lease as of the date of such Taking by giving written notice
to Landlord within 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.

            (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 any of the proceeds received for a Taking to a Landlord's
Mortgagee, then Landlord
<PAGE>   27
may terminate this Lease by delivering written notice thereof to Tenant within
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 14.(b).

            (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.

      15.   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 ninety (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
Premises or 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 estimates that
the damage caused thereby cannot be repaired within two hundred ten (210) days
after the Casualty, then Tenant may terminate this Lease by delivering written
notice to Landlord of its election to terminate within 30 days after the Damage
Notice has been delivered to Tenant. If Tenant does not so timely terminate this
Lease, then (subject to Section 15.(c)) Landlord shall repair the Building or
the Premises, as the case may be, as provided below, and Rent for the portion of
the Premises 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, and Landlord makes a good faith determination that restoring the
Premises would be uneconomical, or if Landlord is required to pay 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 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.

            (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 the Premises and shall proceed
with reasonable diligence to restore the Building and Premises to substantially
the same condition as they existed
<PAGE>   28
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.
If the Premises are not substantially restored within two hundred ten (210) days
after a Casualty, Tenant shall have the right to terminate this Lease upon at
least sixty (60) days prior written notice; provided, however, if Landlord
substantially restores the Premises within said sixty-day period, Tenant's
termination notice shall be null and void and the provisions of this Lease shall
remain in full force and effect.

      16. 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.

      17. EVENTS OF DEFAULT. Each of the following occurrences shall be an
"EVENT OF DEFAULT":

            (a) Tenant's failure to pay Rent within five days after Landlord has
delivered 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 17.(a) on more than
one occasion during the twelve (12) month interval preceding such failure by
Tenant;

            (b) an Event of Default occurs under that certain Lease Agreement
dated January 31, 2000 by and between Landlord and Tenant with respect to the
premises known and numbered as 16 Elizabeth Drive, Chelmsford, Massachusetts
(the "16 ELIZABETH DRIVE LEASE");

            (c) Tenant abandons the Premises or any substantial portion thereof;

            (d) Tenant fails to comply with the Permitted Use set forth herein
and the continuance of such failure for a period of five (5) days after Landlord
has delivered to Tenant written notice thereof;

            (e) Tenant fails to provide any estoppel certificate within the time
period required under Section 25.(e) and such failure shall continue for five
days after written notice thereof from Landlord to Tenant;
<PAGE>   29
            (f) 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 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 seventy-five (75) days after the
delivery of such notice; and

            (g) The filing of a petition by or against Tenant (the term "TENANT"
shall include, for the purpose of this Section 17.(g), 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
90 days after the filing thereof.

      18. 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 due under Section
19.(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, discounted to present value at
a per annum rate equal to the "Prime Rate" as published on the date this Lease
is terminated by The Wall Street Journal, Northeast Edition, in its listing of
"Money Rates," minus one percent, similarly discounted, minus (B) the then
present fair rental rate value of the Premises for such period;

            (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 19.(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 out-of-pocket 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 other portions of the Building. Landlord
shall not be liable for, nor shall Tenant's obligations hereunder be diminished
because of, Landlord's failure to
<PAGE>   30
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 18.(b). If Landlord elects to proceed under this Section 18.(b), it
may at any time elect to terminate this Lease under Section 18.(a); or

            (c) Additionally, upon five (5) days prior written notice, 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 except as otherwise expressly provided herein; 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.

      19.   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 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 the state in which the Premises are located 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
<PAGE>   31
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.

      20. 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.

      21. 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 14 and 15 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 or elsewhere in the Building by Tenant (but Tenant may not remove any
such item which was paid for, in whole or in part, by Landlord or any wiring or
cabling unless Landlord requires such removal). Additionally, at Landlord's
option, Tenant shall remove such alterations, additions, improvements, trade
fixtures, personal property, equipment, wiring, cabling, and furniture as
Landlord may request; however, Tenant shall not be required to remove any
addition or improvement to the Premises if Landlord has specifically agreed in
writing that the improvement or addition in question need not be removed. Tenant
shall repair all damage caused by such removal. All items not so removed shall,
at Landlord's option, 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;
any such disposition shall not be considered a strict foreclosure or other
exercise of Landlord's rights in respect of the security interest granted under
Section 20. The provisions of this Section 21 shall survive the end of the Term.

      22. 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 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 the
greater of (a) 150% of the daily Basic Rent payable during the last month of the
Term, or (b) 125% of the prevailing rental rate in the Building for similar
space. The provisions of this Section 22 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.
<PAGE>   32
      23. 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 (after
giving Tenant reasonable notice thereof, which may be oral notice, except in
cases of real or apparent 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; to change the name of the
Building; and to change the arrangement and location of entrances or
passageways, doors, and doorways, corridors, elevators, stairs, restrooms, or
other public parts of the Building;

            (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 12 months of the Term,
tenants.

      24.   [INTENTIONALLY OMITTED]

      25.   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 arising after the date of transfer, 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
<PAGE>   33
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.

            (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 CRESA Partners, 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.

            (e) ESTOPPEL CERTIFICATES. From time to time, Tenant shall furnish
to any party designated by Landlord, within ten days after Landlord has made a
request therefor, a certificate signed by Tenant confirming and containing such
factual certifications and representations as to this Lease as Landlord may
reasonably request. Unless otherwise required by Landlord's Mortgagee or a
prospective purchaser or mortgagee of the Building, the initial form of estoppel
certificate to be signed by Tenant is attached hereto as Exhibit F.

            (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 in the Basic Lease
Information, (2) hand delivered to the intended address, (3) sent by a
nationally recognized overnight courier service, or (4) sent by facsimile
transmission during normal business hours followed by a confirmatory letter sent
in another manner permitted hereunder. 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 unless such waiver is
in writing signed by Landlord, 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 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
<PAGE>   34
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.

            (k) NO OFFER. The submission of this Lease to Tenant shall not be
construed as an offer, and Tenant shall not have any rights under this Lease
unless Landlord executes a copy of this Lease and delivers it to Tenant.

            (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.

            (p) FINANCIAL REPORTS. Within 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. If Tenant is a publicly
traded corporation, Tenant may satisfy its obligations hereunder by providing to
Landlord Tenant's most recent annual and quarterly reports. Tenant will discuss
its financial statements with Landlord and will give
<PAGE>   35
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 (3) if required by court
order. Tenant shall not be required to deliver the financial statements required
under this Section 25.(p) more than once in any 12-month period unless requested
by Landlord's Mortgagee or a prospective buyer or lender of the Building or an
Event of Default occurs.

            (q) LANDLORD'S FEES. Whenever Tenant requests Landlord to take any
action not required of it hereunder or give any consent required or permitted
under this Lease, Tenant will reimburse Landlord for Landlord's reasonable
out-of-pocket costs payable to third parties and incurred by Landlord in
reviewing the proposed action or consent, including without limitation
reasonable attorneys', engineers' or architects' fees, within ten 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.

            (r) TELECOMMUNICATIONS. Tenant and its telecommunications companies,
including but not limited to local exchange telecommunications companies and
alternative access vendor services companies shall have no right of access to
and within the Building, for the installation and operation of
telecommunications systems including but not limited to voice, video, data, and
any other telecommunications services provided over wire, fiber optic,
microwave, wireless, and any other transmission systems, for part or all of
Tenant's telecommunications within the Building and from the Building to any
other location without Landlord's prior written consent (which consent shall not
be unreasonably withheld or delayed). Notwithstanding any provisions of this
Section 25.(r) to the contrary, and provided Tenant obtains Landlord's prior
written consent as aforesaid, Tenant may make or perform certain installations
affecting Tenant's telecommunications systems provided that: (i) any such
installations only affect the Premises; (ii) no such installations affect any of
the Building HVAC, mechanical, electrical or plumbing systems; (iii) Tenant
shall promptly repair and restore any damage caused by any such installation;
and (iv) upon Landlord's request, at the earlier termination or expiration of
this Lease, Tenant shall restore the Premises to the condition that existed on
the date of this Lease.

            (s) CONFIDENTIALITY. Tenant acknowledges that the terms and
conditions of this Lease are to remain confidential for Landlord's benefit, and
may not be disclosed by Tenant to anyone, by any manner or means, directly or
indirectly, without Landlord's prior written consent. The consent by Landlord to
any disclosures shall not be deemed to be a waiver on the part of Landlord of
any prohibition against any future disclosure.

            (t) HAZARDOUS MATERIALS. The term "HAZARDOUS MATERIALS" means any
substance, material, or waste which is now or hereafter classified or considered
to be hazardous, toxic, or dangerous under any Law relating to pollution or the
protection or regulation of human health, natural resources or the environment,
or poses or threatens to
<PAGE>   36
pose a hazard to the health or safety of persons on the Premises or in the
Building. Tenant shall not use, generate, store, or dispose of, or permit the
use, generation, storage or disposal of Hazardous Materials on or about the
Premises or the Building except in a manner and quantity necessary for the
ordinary performance of Tenant's business, and then in compliance with all Laws.
If Tenant breaches its obligations under this Section 25.(t), Landlord may
immediately take any and all action reasonably appropriate to remedy the same,
including taking all appropriate action to clean up or remediate any
contamination resulting from Tenant's use, generation, storage or disposal of
Hazardous Materials. Tenant shall defend, indemnify, and hold harmless Landlord
and its representatives and agents from and against any and all claims, demands,
liabilities, causes of action, suits, judgments, damages and expenses (including
reasonable attorneys' fees and cost of clean up and remediation) arising from
Tenant's failure to comply with the provisions of this Section 25.(t). This
indemnity provision shall survive termination or expiration of the Lease.

            (v) TIME OF ESSENCE. Time is of the essence of this Lease and each
and all of its provisions.

            (w) SIGNAGE. Tenant may install, at Tenant's risk and expense, one
(1) sign on the exterior facade of the Building, one (1) sign (4 feet x 4 feet)
on the ground in front of the main entrance of the Building, and one (1) company
identification/directional sign in the same location as the existing company
identification/directional sign and at a size no bigger than such existing sign,

consent, which approval and consent shall not be unreasonably withheld,
conditioned or delayed.

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

            (y) TERMINATION OF PRIOR LEASE. The Lease dated March 17, 1995 by
and between Teachers Insurance and Annuity Association of America (the successor
of
<PAGE>   37
which is Landlord) and Tenant, as amended by that certain First Amendment to
Lease dated as of May 15, 1998 by and between Landlord and Tenant (as amended
the "PRIOR LEASE") for the Premises shall be automatically terminated and,
subject to the provisions of this Section 25(y), of no further force and effect
upon the date ("TERMINATION DATE") that each of the following has occurred:

                  (i)   the Commencement Date (as herein defined) has
                        occurred; and

                  (ii)  Tenant has paid rent and all other amounts due and
                        payable by Tenant to Landlord for the period up
                        through and including the Termination Date under
                        the Prior Lease (including, without limitation,
                        all Taxes and Operating Expenses (as such terms
                        are defined under the Prior Lease) due and owing
                        up through and including the Termination Date
                        which may be adjusted after the Termination Date;
                        provided however, adjustments to Taxes and
                        Operating Expenses may be paid after the
                        Termination Date provided such Taxes and Operating
                        Expenses are paid in accordance with the
                        provisions of the Prior Lease), which obligations
                        shall survive the early termination of the Prior
                        Lease.

After the Termination Date, Tenant shall perform all obligations under the Prior
Lease which expressly survive the expiration or termination of such Lease,
including, without limitation, the provisions of Sections 10.1 and 14.25
thereof. Except as set forth herein, all rights and obligations of the parties
under the Prior Lease shall cease as of the Termination Date.

            (z) FAILURE OF TENANT TO CONTINUOUSLY OCCUPY THE PREMISES. If, for
more than one hundred eighty (180) consecutive days or more than one hundred
eighty (180) days in a three hundred sixty-five (365) day period, Tenant (1)
vacates the Premises or (2) fails to continuously operate its business therein,
Landlord may terminate the Lease upon giving written notice to Tenant as of the
date specified in such notice. If Landlord terminates this Lease, then this
Lease shall terminate and neither party shall have any further obligations
hereunder as of the terminate date except as otherwise provided herein and
Tenant shall pay to Landlord all Rent accrued through the termination date.
Thereafter, Landlord may lease the Premises (or any portion thereof) to any
person without liability to Tenant.

            (aa) 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. The Rooftop Equipment shall be used only by
Tenant. Before installing the Rooftop Equipment, Tenant shall submit to Landlord
for its approval (which approval shall not be unreasonably withheld, conditioned
or delayed to the extent such plans and specifications do not reflect
alterations which affect the exterior or
<PAGE>   38
structure of the Building or its HVAC, plumbing or mechanical systems or its
base building electrical system) 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, regulations, restrictions (governmental or otherwise)
and architectural guidelines in effect for the area in which the Building is
located as they may be amended from time to time (the "LEGAL REQUIREMENTS").
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, Tenant shall install (in a good and workmanlike
manner), maintain and use the Rooftop Equipment in accordance with all Legal
Requirements 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 and operate and maintain the Rooftop Equipment in such a manner so as
not to unreasonably interfere with any equipment (including any other satellite,
antennae, or other transmission facility) on the Building's roof or in the
Building. Landlord may require that Tenant screen the Rooftop Equipment with a
parapet or other screening device reasonably 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, unless
said relocation is requested because the Rooftop Equipment is unreasonably
interfering with other equipment on the Building's roof or in the Building (in
which case Tenant shall pay for the cost of such relocation). Upon Landlord's
written request (but not otherwise), 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
<PAGE>   39
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.

            (bb) NOTICE OF LEASE. Tenant agrees not to record this Lease and,
subject to the provisions of Section 25.(s) above, to keep the terms of this
Lease confidential, but each party hereto agrees, at the request of the others
to execute a so-called Notice of Lease in recordable form complying with
applicable law and reasonably satisfactory to Landlord's attorneys. In no event
shall such document set forth the Rent or other charges payable by Tenant
hereunder.

            (cc) LANDLORD'S AUTHORITY, ETC. Landlord represents and warrants
that (i) it is the record owner of the Premises in fee simple, (ii) it has full
right and authority to execute this Lease, and (iii) this Lease does not
conflict with any other agreement to which Landlord is bound.

            (dd) FIBER OPTIC LINES. Subject to the provisions of Section 8
above, Tenant, at its sole cost and expense and with Landlord's prior written
consent (which consent shall not be unreasonably withheld or delayed), may
install underground fiber optic lines within the Premises. Notwithstanding any
provisions of this Section 25.(dd) to the contrary, Landlord shall not be deemed
to have unreasonably withheld its consent to any installation that would affect
the Building's structure or its HVAC, plumbing, electrical, or mechanical
systems. Tenant shall promptly repair and restore any damage caused by any such
installation and, upon Landlord's request, at the earlier termination or
expiration of this Lease, Tenant shall restore the Premises to the condition
that existed on the date of this Lease. Any and all such installations of fiber
optic lines shall comply with all applicable Laws.

      26. OTHER PROVISIONS. LANDLORD AND TENANT EXPRESSLY DISCLAIM ANY IMPLIED
WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANT'S INTENDED COMMERCIAL
PURPOSE, AND, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, TENANT'S OBLIGATION
TO PAY RENT HEREUNDER IS NOT DEPENDENT UPON THE CONDITION OF THE PREMISES OR THE
PERFORMANCE BY LANDLORD OF ITS OBLIGATIONS HEREUNDER, AND, EXCEPT AS OTHERWISE
EXPRESSLY PROVIDED HEREIN, TENANT SHALL CONTINUE TO PAY THE RENT, WITHOUT
ABATEMENT, SETOFF OR DEDUCTION, NOTWITHSTANDING ANY BREACH BY LANDLORD OF ITS
DUTIES OR OBLIGATIONS HEREUNDER, WHETHER EXPRESS OR IMPLIED.

                  [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK]

      IN WITNESS WHEREOF, and in consideration of the mutual entry into this
Lease and for other good and valuable consideration, and intending to be legally
bound, each party hereto has caused this Lease Agreement to be duly executed as
a Massachusetts instrument under seal as of the day and year first above
written.

                                 EXHIBIT D

                       TENANT FINISH-WORK: ALLOWANCE

      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. 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, delayed or conditioned), of all
alterations, improvements and installations that Tenant proposes to construct,
install and complete 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 alterations, improvements and installations 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 or disapproval, as the case may be, of the final working
drawings (inclusive of any approval required by the Building's engineer of
record) shall be completed within ten (10) business days of Landlord's receipt
of such working drawings. If Landlord disapproves the final working drawings,
Landlord shall specify the reasons for such disapproval in writing to Tenant.
Landlord's approval of such working drawings shall not be unreasonably withheld,
delayed or conditioned, provided that (a) they comply with all applicable laws,
rules, and regulations, (b) such working drawings are sufficiently detailed to
allow construction of the alterations, improvements and installations in a good
and workmanlike manner, (c) the alterations, improvements and installations
depicted thereon conform to the rules and regulations promulgated from time to
time by Landlord for the construction of tenant alterations, improvements and
installations (a copy of which has been delivered to Tenant), and (d) the
alterations, improvements and installations do not affect the Building's
Structure or any of its HVAC, electrical, mechanical or plumbing systems. 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 alterations, improvements and installations to be
constructed in accordance with and as indicated on the Working Drawings.
Landlord's approval of the Working Drawings shall not be a representation or
warranty of Landlord that such drawings 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 (which approval shall not be withheld, delayed or conditioned), 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>   47
      3. The Work shall be performed only by contractors and subcontractors
approved in writing by Landlord, which approval shall not be unreasonably
withheld or delayed. 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 and
delivery of the Premises to Tenant, 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, and shall be performed in such a
manner and at such times as not to interfere with or delay Landlord's other
contractors, the operation of the Building, and the occupancy thereof by other
tenants. 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.).

      4. 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.

      5. Landlord shall provide to Tenant a construction allowance (the
"CONSTRUCTION ALLOWANCE") equal to the lesser of (a) $5.50 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, or a portion of the Work, shall be, in
Landlord's reasonable discretion, substantially complete; (iv) Tenant shall
furnish to Landlord: (A) if the entire Work is substantially complete, 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,
or in the case of completion of a portion of the Work, have been paid and that
no lien exists of record with respect thereto; and (v) Tenant shall not request
any portion of the Construction Allowance more than once a month. 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.
<PAGE>   48
      6. 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 and approve the Working Drawings and/or any drafts and/or
modifications thereto and to review the construction of the Work.

      7. At Tenant's election and subject to Tenant's prior written notice of
same to Landlord, Tenant may use all or a portion of the Construction Allowance
(as defined above) to finance all or a portion of the Work as defined above
and/or all or a portion of the Work as defined in the 16 Elizabeth Drive Lease
subject to the provisions of this Lease as they relate to construction of the
Work as defined above and to the provisions of the 16 Elizabeth Drive Lease as
they relate to construction of the Work as defined in the 16 Elizabeth Drive
Lease.

                                    By:

                                 RENEWAL OPTION

      Provided no Event of Default exists and Tenant is occupying the entire
Premises at the time of such election, Tenant may renew this Lease for one
additional period of five (5) years, by delivering written notice of the
exercise thereof to Landlord not earlier than fifteen (15) months nor later than
twelve (12) months before the expiration of the Term. The Basic Rent payable for
each month during such extended Term shall be the prevailing rental rate (the
"PREVAILING RENTAL RATE"), at the commencement of such extended Term, for
renewals of 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. Within thirty (30) days after receipt of Tenant's notice to renew,
Landlord shall deliver to Tenant written notice of the Prevailing Rental Rate
and shall advise Tenant of the required adjustment to Basic Rent, if any, and
the other terms and conditions offered. Tenant shall, within ten (10) days after
receipt of Landlord's notice, notify Landlord in writing whether Tenant accepts
or rejects Landlord's determination of the Prevailing Rental Rate. If Tenant
timely notifies Landlord that Tenant accepts Landlord's determination of the
Prevailing Rental Rate (and failure of Tenant to notify Landlord within the time
period prescribed above shall be deemed acceptance) or if, after a timely
rejection by Tenant of such determination, the Prevailing Rental Rate is
determined according to the procedures set forth in this Exhibit, then, on or
before the commencement date of the extended Term, 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) Basic Rent shall be adjusted to the Prevailing Rental Rate;

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

            (c) Landlord shall lease to Tenant the Premises in their
      then-current condition, and Landlord shall not provide to Tenant any
      allowances (e.g., moving allowance, construction allowance, and the like)
      or other tenant inducements.

If Tenant rejects Landlord's determination of the Prevailing Rental Rate, Tenant
may, but only within ten (10) days after receipt of Landlord's notice, require
by written notice to Landlord that the determination of Prevailing Rental Rates
be made by brokers. In such event, within ten (10) days thereafter, each party
shall select a qualified commercial real estate broker with at least ten (10)
years experience in appraising property and buildings in the city or submarket
in which the Premises are located. The two brokers shall give their opinion of
Prevailing Rental Rates within ten (10) days after their retention. In the event
the opinions of the two brokers differ and, after good faith efforts over the
succeeding ten (10) day period, they cannot mutually agree, the brokers shall
immediately and jointly appoint a third broker with the qualifications specified
above. This third broker shall immediately (within five (5) days) choose either
the determination of
<PAGE>   55
Landlord's broker or Tenant's broker and such choice of this third broker shall
be final and binding on Landlord and Tenant. Each party shall pay its own costs
for its real estate broker. The parties shall equally share the costs of any
third broker. The parties shall immediately confirm the renewal term, Basic Rent
and the other terms and conditions so determined, in writing.

      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 any portion of the Premises, (3)
Tenant fails to timely exercise its option under this Exhibit, time being of the
essence with respect to Tenant's exercise thereof, or (4) Landlord determines,
in its sole but reasonable discretion, that Tenant's financial condition or
creditworthiness has materially deteriorated since the date of this Lease.

             SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT

      This AGREEMENT is made and entered into as of ___________________, 2000,
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 Brooks
Automation, Inc. ("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
31, 2000 (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 beyond any applicable grace periods under any
provision of the Lease or this Agreement 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
<PAGE>   62
      (d) Tenant attorns to or at the direction of Lender, as provided in
Paragraph 5. 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>   63
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 Joint and Several. Landlord and Tenant hereby jointly and
severally 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) Tenant has accepted possession of the Demised Premises, is in
occupancy thereof under the Lease, and the term commenced on ____________ ___ ,
2000.

      (c) Under the Lease, Tenant is presently obligated to pay rent without
present right of defense or offset, at the rate of $47,932.50 per month. Rent is
paid through and including ______________ ___, 2000. 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 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
<PAGE>   64
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.

      (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
<PAGE>   65
as Lender proceeds promptly to acquire possession of the Demised Premises with
due diligence, by foreclosure of the Mortgage or otherwise.

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
after having been mailed by registered or certified mail, return receipt
requested, or by express mail, in any event with sufficient postage affixed, and
addressed to the parties as follows:

notice of change of address is effective only upon receipt. Landlord and Tenant
jointly and severally agree that they will furnish Lender with copies of all
notices relating to the Lease. All communications to Lender shall reference
"AMRESCO Loan No.: __________ ".

      12. SUCCESSORS AND ASSIGNS. As used in this Agreement, the word "Tenant"
shall mean Tenant and any subsequent holder or holders of an interest under the
Lease, as the text may require, provided that the interest of such holder is
acquired in accordance with the terms and provisions of the Lease and the word
"Lender" shall mean Lender or any other subsequent holder or holders of the
Mortgage or any party acquiring title to the Demised Premises by purchase at a
foreclosure sale, by deed of the Lender, or otherwise. Subject to the foregoing,
this Agreement shall bind and inure to the benefit of Landlord, Tenant and
Lender, their legal representatives, successors and assigns. The terms Lease,
Mortgage and Lease Assignment shall include any and all amendments,
modifications, replacements, substitutions, extensions, renewals and supplements
thereto.

      13. FURTHER ASSURANCES. Landlord and Tenant from time to time shall
execute and deliver at Lender's request all instruments that may be necessary or
appropriate to evidence their agreement hereunder provided such instrument
neither increases Tenant's obligations or decreases its rights under the Lease.

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

      15. SEVERABILITY. A determination that any provision of this Agreement is
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.

                                      LEASE


      THIS LEASE AGREEMENT (this "LEASE") is entered into as of January 31,
2000, between W9/TIB REAL ESTATE LIMITED PARTNERSHIP, a Delaware limited
partnership ("LANDLORD"), and BROOKS AUTOMATION, INC., a Delaware corporation
("TENANT").

      1. DEFINITIONS AND BASIC PROVISIONS. The definitions and basic provisions
set forth in the Basic Lease Information (the "BASIC LEASE INFORMATION")
executed by Landlord and Tenant contemporaneously herewith are incorporated
herein by reference for all purposes. Additionally, the following terms shall
have the following meanings when used in this Lease: "LAWS" means all federal,
state, and local laws, rules and regulations, all court orders, governmental
directives, and governmental orders, and all restrictive covenants affecting the
Property, and "LAW" shall mean any of the foregoing; "AFFILIATE" means any
person or entity which, directly or indirectly, through one or more
intermediaries, controls, is controlled by, or is under common control with the
party in question; "TENANT PARTY" means any of the following persons: Tenant;
any assignees claiming by, through, or under Tenant; any subtenants claiming by,
through, or under Tenant; and any of their respective agents, contractors,
employees, and invitees; and "INCLUDING" means including, without limitation.

      2. LEASE GRANT. Subject to the terms of this Lease, Landlord leases to
Tenant, and Tenant leases from Landlord, the Premises.

      3. TERM. Landlord shall deliver possession of the Premises to Tenant
promptly after each party executes this Lease (the "ESTIMATED DELIVERY DATE").
If the Premises are not delivered to Tenant on the Estimated Delivery Date, then
(a) Landlord shall not be in default hereunder or be liable for damages
therefor, and (b) Tenant shall accept possession of the Premises when Landlord
tenders possession thereof to Tenant. By occupying the Premises, Tenant shall be
deemed to have accepted the Premises in their condition as of the date of such
occupancy. Tenant shall execute and deliver to Landlord, within ten days after
Landlord has requested the same, an amendment substantially in the form of
Exhibit E hereto confirming the Commencement Date and the expiration date of the
initial Term, that Tenant has accepted the Premises, and that Landlord has
performed all of its obligations with respect to the Premises.

      4. RENT.

            (a) PAYMENT. Tenant shall timely pay to Landlord Basic Rent and all
additional sums to be paid by Tenant to Landlord under this Lease, without
notice, deduction or set off, except as otherwise expressly set forth herein, at
Landlord's address provided for in this Lease or as otherwise specified by
Landlord and shall be accompanied by all applicable state and local sales or use
taxes. Basic Rent, adjusted as herein provided, shall be payable monthly in
advance. The first monthly installment of Basic Rent shall be payable
contemporaneously with the execution of this Lease;
<PAGE>   10
thereafter, Basic Rent shall be payable on the first day of each month beginning
on the first day of the second 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.

            (b) OPERATING COSTS; TAXES; ELECTRICAL COSTS.

                  (1) Tenant shall pay all of the Operating Costs (defined
below) ("ADDITIONAL RENT"). 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 than twice in any Lease Year),
Landlord may estimate and re-estimate the Additional Rent to be due by Tenant
and deliver a copy of the estimate or re-estimate to Tenant, which estimate
shall itemize each increased cost. 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 sound accounting principles consistently applied,
including, but not limited to, the following costs: (A) wages and salaries
(management fees, which management fees shall not exceed fair market management
fees for comparable buildings in the Greater Boston area) of all employees
engaged in the operation, maintenance, and security of the Premises, including
taxes, insurance and benefits relating thereto; (B) all supplies and materials
used in the operation, maintenance, repair, replacement, and security of the
Premises; (C) costs for improvements made to the Premises which, although
capital in nature, are expected to reduce the normal operating costs (including
all utility costs) of the Premises, as well as capital improvements made in
order to comply with any law hereafter promulgated by any governmental authority
and capital improvements related to roof replacement and replacement of rooftop
HVAC units, as 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 reimbursable to Landlord by Tenant other than
pursuant to a provision similar to this Section 4.(b); (E) insurance expenses;
(F) repairs, replacements, and general maintenance of the Premises; (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);
and (H) accounting fees incurred by Landlord for the accounting services
performed in connection with the Premises.
<PAGE>   11
                  Operating Costs shall not include costs for (i) capital
improvements made to the Premises, other than capital improvements described in
Section 4.(b)(2)(C) and except for items which are generally considered
maintenance and repair items, such as painting of common areas, replacement of
carpet in elevator lobbies, and the like; (ii) repair, replacements and general
maintenance paid by proceeds of insurance or by Tenant or other third parties;
(iii) interest, amortization or other payments on loans to Landlord or any
ground lease rent; (iv) depreciation; (v) leasing commissions; (vi) legal
expenses for services, other than those that benefit the Building tenants
generally (e.g., tax disputes); (vii) Taxes (defined below); (viii) franchise or
federal income taxes imposed on or measured by the income of Landlord from the
operation of the Building; (ix) any cost or expense to the extent to which
Landlord is paid or reimbursed (other than as a payment for Operating Costs);
(x) salaries and bonuses of officers and executives of Landlord; (xi) any fees,
costs, and commissions incurred in procuring or attempting to procure tenants
including, but not necessarily limited to brokerage commissions, finders fees,
attorney's fees and expenses, entertainment costs and travel expenses; (xii) the
cost of advertising or promotion for the Building; (xiii) any capital cost
necessary to cure any violation of any law, ordinance or regulation applicable
to the Building existing as of the date of the Lease or to remediate any
environmental condition (existing as of the date of the Lease); (xiv) reserves;
(xv) Landlord's charitable or political contributions; (xvi) Landlord's travel
or entertainment expenses; (xvii) depreciation of the Building; (xviii) provided
Tenant is not in default of any provisions of this Lease beyond all applicable
notice and cure periods, fines or penalties arising solely out of Landlord's
breach of any obligation hereunder; and (xix) all costs incurred to perform the
work outlined in the HVAC Replacement/Repair Specifications (as that term is
hereinafter defined in Exhibit D).

                  (3) Tenant shall also pay all of 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 Premises (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 Premises, 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). 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 Premises. For property tax
purposes, Tenant waives all rights to protest or appeal the appraised value of
the Premises, as well as the Building, and all rights to receive notices of
reappraisement. Taxes shall be deemed payable over the longest period allowed by
law. Tenant may file for and prosecute tax abatements pertaining to the Premises
only after it has notified Landlord that Tenant desires Landlord pursue a tax
abatement and
<PAGE>   12
Landlord elects not to pursue such a tax abatement and so notifies Tenant in
writing. If Tenant files for and prosecutes a tax abatement pertaining to the
Premises, Tenant shall simultaneously provide Landlord with all filings made
with the taxing authorities and with any other information reasonably requested
by Landlord.

                  (4) Intentionally Omitted.

                  (5) By April 1 of each calendar year, or as soon thereafter as
reasonably practicable, Landlord shall furnish to Tenant a statement of
Operating Costs for the previous year, 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 Tenant's
actual Additional Rent or Taxes due, then Tenant shall promptly pay Landlord
such deficiency.

                  (6) Provided (A) Tenant is not in default hereunder, and (B)
Tenant has paid Landlord the Operating Costs in question, Tenant shall have the
right, exercisable not more than once each Lease Year, to examine Landlord's
books and records relating to Operating Costs for the prior Lease Year only.
Such examination shall be performed (i) at Landlord's office, (ii) at Tenant's
sole cost and expense, (iii) upon prior reasonable written notice to Landlord,
(iv) during normal business hours, and (v) within sixty (60) days after receipt
of the Operating Costs and Tax Statement. In the event Tenant's examination
reveals a discrepancy, Landlord shall promptly (but no later than thirty (30)
days) reimburse Tenant for the amount of any overpayment. If Tenant's
examination of Landlord's books and records reveals an overcharge of more than
five percent (5%), Landlord shall, within thirty (30) days after receipt of a
written invoice, reimburse Tenant for the reasonable costs of such audit. In
conducting such audit, Tenant shall use an independent certified public
accountant experienced in auditing Operating Costs, which accountant shall be
paid on an hourly basis (and not on a contingency or success fee basis). Such
audit shall be conducted in accordance with generally accepted rules of auditing
practices. Any information obtained by Tenant pursuant to the provisions of this
Section 3(b)(6) shall be treated as confidential.

            (c) BILLING FOR ELECTRICITY. Tenant shall pay (as hereinafter
described) for the use of all electrical service to the Premises. Tenant shall
be billed directly by such utility company and Tenant agrees to pay each bill
promptly in accordance with its terms, and upon default in making any such
payment which continues for more than ten (10) days after written notice to
Tenant, Landlord may pay such charges and collect the same from Tenant. In the
event for any reason Tenant cannot be billed directly, Landlord shall forward
each bill received with respect to the Building to Tenant, which Tenant shall
pay within thirty (30) days of receiving each such bill unless the terms of the
each such bill specify otherwise.
<PAGE>   13
      5. DELINQUENT PAYMENT; HANDLING CHARGES. All past due payments required of
Tenant hereunder shall bear interest from the date due until paid at the lesser
of fifteen percent per annum or the maximum lawful rate of interest;
additionally, if Tenant fails to make any payment due hereunder more than once
in any Lease Year, Landlord may charge Tenant a fee equal to 5% of the
delinquent payment to reimburse Landlord for its cost and inconvenience incurred
as a consequence of Tenant's delinquency. In no event, however, shall the
charges permitted under this Section 5 or elsewhere in this Lease, to the extent
they are considered to be interest under applicable Law, exceed the maximum
lawful rate of interest.

      6. SECURITY DEPOSIT. Contemporaneously with the execution of this Lease,
Tenant shall pay to Landlord the Security Deposit, which Security Deposit shall
be the same Security Deposit held under this Lease and under the 15 Elizabeth
Drive Lease (as hereinafter defined in Section 17(b)) and shall be held by
Landlord to secure Tenant's performance of its obligations under this Lease and
under the 15 Elizabeth Drive Lease. If, for whatever reason, either this Lease
or the 15 Elizabeth Drive Lease terminates prior to the stated expiration date
and/or the Term of only one of said Leases is extended and no further
obligations are due and owing under the expired and/or terminated Lease, the
Security Deposit shall continue to secure Tenant's obligations under the
applicable Lease which has not expired and/or terminated. 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 17). Landlord may, from time to
time following an Event of Default 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 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 or
return same to Tenant and Landlord thereafter shall have no further liability
for the return of the Security Deposit.

      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 $1,000,000.00 (the "LETTER OF CREDIT"), in the form
of the sample letter of credit attached hereto as Exhibit J 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
<PAGE>   14
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 upon the earlier of (x) the expiration of said
sixty-day period or (y) at least forty-five (45) 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 6); 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.

      Notwithstanding any of the foregoing provisions of this Section 6 to the
contrary, if Tenant has a Tangible Net Worth of at least $165,000,000.00 on the
eighteenth (18th) month after the Commencement Date (the "REDUCTION DATE"), the
Security Deposit (or the applicable Letter or Credit) shall be reduced by
$500,000.00, provided that on the Reduction Date (i) the Lease is in full force
and effect, (ii) no Event of Default exists, (iii) no Event of Default has
occurred, and (iv) Tenant has not assigned this Lease to anyone other than a
Permitted Transferee. If on the Reduction Date the Security Deposit (or the
applicable Letter of Credit) shall not be reduced because one or more of the
conditions set
<PAGE>   15
forth in clauses (i), (ii) or (iii) above cease to exist on the Reduction Date,
the Security Deposit (or applicable Letter of Credit) shall not be reduced
during any succeeding calendar year. If on the Reduction Date the Security
Deposit (or applicable Letter of Credit) shall not be reduced because only the
condition set forth in clause (iv) above (as opposed to the conditions set forth
in any of clauses (i), (ii) or (iii) above) ceases to exist on the Reduction
Date and/or Tenant does not have a Tangible Net Worth of at least
$165,000,000.00 on the Reduction Date, the Security Deposit (or applicable
Letter of Credit) shall be so reduced on the date that Tenant has achieved a
Tangible Net Worth of $165,000,000.00, provided the conditions set forth in
clauses (i), (ii), (iii) and (iv) above exist on such date. If the Security
Deposit (or applicable Letter of Credit) is reduced pursuant to the foregoing
provisions, Landlord shall return the amount of the reduction if Tenant paid the
Security Deposit in cash or Tenant may replace and/or amend the Letter of Credit
accordingly.

      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 6, 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.
<PAGE>   16
      7.    LANDLORD'S OBLIGATIONS

            (a) SERVICES. Landlord shall furnish to Tenant the following
services (the cost of which services shall be considered Operating Costs): (1)
water at those points of supply to the Building as currently exist; (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 holidays, for Building-standard installations and such
window washing as may from time to time be reasonably required; (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 if any person(s) other than Tenant or any assignees or sublessees of
Tenant permitted hereunder occupies any portion of the Premises; and (5)
electrical current 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 7.(a) with reputable, licensed (if applicable) 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 7.(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 7.(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 at
least twenty (20) days prior written notice to Tenant (except in the event of an
emergency or in situations where Landlord's prompt action is necessary to
prevent damage or deterioration to any portion of the Premises, in which case,
no advance notice shall be required) elect to provide such services and the
management fee shall no longer be reduced; provided, however, to the extent the
twenty-day grace period exists, Landlord's election shall be deemed null and
void and of no further force and effect if Tenant causes the services being
performed at an unsatisfactory level to be performed at a satisfactory level
within the twenty-day period.
<PAGE>   17
      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 7.(a). If Tenant is engaging providers of such services in
accordance with the provisions of this Lease, Landlord may perform periodic
inspections of the Building and all such inspection costs shall be considered an
Operating Cost and paid by Tenant in accordance with Section 4 above. However,
upon sixty (60) days prior written notice to Landlord, Tenant may elect to have
Landlord provide such services.

            (b) LANDLORD'S MAINTENANCE OBLIGATIONS. This Lease is intended to be
a net lease; accordingly, Landlord's maintenance obligations (other than those
set forth in Section 7(a), if applicable) 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, maintenance and/or replacement of the
roof, which repair, maintenance and/or replacement costs shall be considered an
Operating Cost and paid by Tenant in accordance with Section 4 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. Notwithstanding any
provisions of this Lease to the contrary, Landlord may replace the roof and the
roof membrane at any time, but shall be required to replace the roof and the
roof membrane if the cost to repair the roof and the roof membrane over an
aggregate twelve-month period exceeds $30,000.00 provided that such repair work
is not necessitated by either a catastrophic failure caused by severe weather
events or any act or omission by or on behalf of any Tenant Party.

            (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 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 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 Building
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
<PAGE>   18
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, or entail excessive or
unreasonable alterations, repairs, or expenses. 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 more than fifteen (15)
consecutive business days because of the unavailability of any such service and
such unavailability was not caused by a Tenant Party, then Tenant shall, as its
exclusive remedy be entitled to a reasonable abatement of Rent for each
consecutive day (after such 15-day period) that Tenant is so prevented from
using the Premises.

            (e) LANDLORD'S COMPLIANCE WITH APPLICABLE LEGAL REQUIREMENTS.
Landlord shall comply with all legal requirements directly applicable to the
structural elements of the Building; but only to the extent that a failure to so
comply shall materially affect the Building, Tenant's use thereof or Tenant's
access thereto or results in Tenant being held responsible for the violation.
Landlord may contest in good faith the validity or application of any legal
requirements with which Landlord may be obligated to comply. Notwithstanding the
foregoing, all expenses incurred by Landlord to comply with all such legal
requirements enacted after the date of this Lease shall be considered an
Operating Cost and paid by Tenant in accordance with Section 4 above.

      8. IMPROVEMENTS; ALTERATIONS; REPAIRS; MAINTENANCE.

            (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 Building,
without the consent of Landlord and without Landlord's approval of plans,
provided: (i) the cost thereof shall not exceed Twenty-Five Thousand Dollars
($25,000.00) in the aggregate in any consecutive twelve-month period; (ii)
Tenant shall, prior to commencing any such alterations, additions and/or
improvements in the Building in connection therewith, furnish Landlord with a
complete set of plans and specifications
<PAGE>   19
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 or plumbing systems of the
Building or the base building electrical system, as such base building
electrical system exists after Tenant's installation of the Work (but such
alterations may include minor electrical alterations not affecting the base
building electrical system); 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 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. Notwithstanding any provisions of the preceding sentence to the
contrary, if Tenant is the sole occupant of the Building, Landlord's prior
written consent shall only be required with respect to the painting or
installation of lighting or decorations, signs, window or door lettering, or
advertising media of any type on or about the Premises which would affect the
exterior of the Building. 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. Landlord shall cooperate with
Tenant in obtaining any permits or licenses sought by Tenant in connection with
the Premises provided Landlord shall never be required to pay any out-of-pocket
expenses in connection therewith.

            (b) REPAIRS; MAINTENANCE. Tenant shall maintain the Premises in a
clean, safe, and operable condition as exists after the construction of the Work
(as hereinafter defined) and any other alterations, additions or improvements
performed by Tenant, reasonable wear and tear and damage by fire, other casualty
and eminent domain excepted, consistent with the operation of a first class
building consistent with the Permitted Use, 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 7.(a) above, Tenant
shall enter into preventative maintenance/service contract(s) with maintenance
contractor(s) reasonably 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. Upon request from Landlord, Tenant shall
provide Landlord with copies of all such preventative maintenance/service
contracts maintained by Tenant. Irrespective of whether or not Tenant elects to
engage providers for all services in accordance with Section 7.(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
<PAGE>   20
replacements within fifteen (15) 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, after written notice to Tenant, make the same at
Tenant's cost. Notwithstanding any provisions of this Lease to the contrary, if
the cost to repair one of the existing rooftop HVAC units exceeds twenty-five
percent (25%) of the replacement cost for such unit, Landlord shall pay for such
replacement cost within twenty (20) business days after satisfaction of the
following terms and conditions: (i) Landlord and Tenant agree in writing on any
such replacement cost, on the specification of the new rooftop unit, and on the
contractor to install such new unit; (ii) Tenant shall ensure such new unit is
installed in accordance with applicable Laws; (iii) Tenant shall not be in
default under this Lease; (iv) this Lease shall be in full force and effect; (v)
Tenant has provided Landlord with evidence reasonably satisfactory to Landlord
that the new unit has been installed in accordance with applicable Laws; (vi)
Tenant has maintained and repaired such unit in accordance with the provisions
of this Lease; and (vii) such replacement costs shall be considered an Operating
Cost and paid by Tenant in accordance with Section 4 above.

            (c) PERFORMANCE OF WORK. All work described in this Section 8 shall
be performed only by Landlord or by contractors and subcontractors reasonably
approved in writing by Landlord. 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 Building (including the Premises, the structural elements, and the
plumbing, electrical lines, or other utility transmission facility). All such
work which may affect the Building's HVAC, electrical, plumbing, other
mechanical systems, or structural elements must be approved by the Building's
engineer of record, at Tenant's expense and, at Landlord's election, must be
performed by Landlord's usual contractor for such work, unless otherwise
approved by Landlord.

      Tenant shall provide sworn statements, including the names, addresses and
copies of contracts for all contractors, and upon completion of any work shall
promptly furnish Landlord with sworn owner's and contractor's statements and
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 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.
<PAGE>   21
            (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. 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 heavy 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, not to be unreasonably
withheld, conditioned or delayed, which consent may include a requirement to
provide insurance, naming Landlord as an insured, in such amounts as Landlord
may deem reasonable.

                  (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.

      9. USE. Tenant shall occupy and use the Premises only for the Permitted
Use, and for no other purposes, and shall comply with all Laws relating to the
use, condition, access to, and occupancy of the Premises. The population density
within the Premises as a whole shall at no time exceed one person for each 200
rentable square feet in 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 Building or its contents, or for the storage
of any Hazardous Materials. If, because of a Tenant Party's acts, the rate of
insurance on the Building or its contents increases, then 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. If Tenant fails to cease or
remediate such acts within five (5) days after Landlord's request that Tenant do
so, then such acts shall be an Event of Default. Tenant shall conduct its
business and control each other Tenant Party so as not to create any nuisance or
unreasonably interfere with other tenants or Landlord in its management of the
Building.

      10. ASSIGNMENT AND SUBLETTING

            (a) TRANSFERS. Except as provided in Section 10.(g), Tenant shall
not, without the prior written consent of Landlord, (1) assign, transfer, or
encumber this Lease
<PAGE>   22
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 10.(a)(1)
through 10.(a)(6) being a "TRANSFER").

            (b) CONSENT STANDARDS. Landlord shall not unreasonably withhold,
condition or delay its consent to any assignment or subletting of the Premises,
provided that the proposed transferee is creditworthy, has a good reputation in
the business community, will use the Premises for the Permitted Use (thus,
excluding, without limitation, uses for credit processing and telemarketing) and
will not use the Premises in any manner that would conflict with any exclusive
use agreement or other similar agreement entered into by Landlord with any other
tenant of the Building, is not a governmental entity, or subdivision or agency
thereof, and is not another occupant of the Building or person or entity with
whom Landlord is negotiating to lease space in the Building; otherwise, Landlord
may withhold its consent in its sole discretion.

            (c) REQUEST FOR CONSENT. 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. Landlord shall approve such request,
or indicate its basis for refusing consent, within thirty (30) days after
receipt of such request and receipt of all of the information enumerated in the
preceding sentence. Concurrently with Tenant's notice of any request for consent
to a Transfer, Tenant shall pay to Landlord a fee of $750 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.

            (d) CONDITIONS TO CONSENT. 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
<PAGE>   23
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.

            (e) CANCELLATION. Landlord may, within 30 days after submission of
Tenant's written request for Landlord's consent to an assignment or subletting,
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. If Landlord
cancels this Lease as to any portion of the Premises, 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.

            (f) ADDITIONAL COMPENSATION. Tenant shall pay to Landlord,
immediately upon receipt thereof, seventy-five percent (75%) of 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.

            (g) PERMITTED TRANSFERS. Notwithstanding Section 10.(a), Tenant may
Transfer all or part of its interest in this Lease or all or part of the
Premises (a "PERMITTED TRANSFER") to the following types of entities (a
"PERMITTED TRANSFEREE") without the written consent of Landlord:

                  (1) an Affiliate of Tenant;

                  (2) any corporation, limited partnership, limited liability
      partnership, limited liability company or other business entity in which
      or with which Tenant, or its corporate successors or assigns, is merged or
      consolidated, in accordance with applicable statutory provisions governing
      merger and consolidation of business entities, so long as (A) Tenant's
      obligations hereunder are assumed by the entity surviving such merger or
      created by such consolidation; and (B) the Tangible Net Worth of the
      surviving or created entity is not less than the greater of (i) the
      Tangible Net Worth of Tenant as of the date hereof, or (ii) the Tangible
      Net Worth of Tenant at the time of any such Permitted Transfer; or

                  (3) any corporation, limited partnership, limited liability
      partnership, limited liability company or other business entity acquiring
      all or substantially all of Tenant's assets if such entity's Tangible Net
      Worth after such acquisition is not less than the greater of (i) the
      Tangible Net Worth of Tenant as of the date hereof, or (ii) the Tangible
      Net Worth of Tenant at the time of any such Permitted Transfer.
<PAGE>   24
      Tenant shall promptly notify Landlord of any such Permitted Transfer.
Tenant shall remain liable for the performance of all of the obligations of
Tenant hereunder, or if Tenant no longer exists because of a merger,
consolidation, or acquisition, the surviving or acquiring entity shall expressly
assume in writing the obligations of Tenant hereunder. Additionally, the
Permitted Transferee shall comply with all of the terms and conditions of this
Lease, including the Permitted Use, and the use of the Premises by the Permitted
Transferee may not violate any other agreements affecting the Premises, the
Building, Landlord or other tenants of the Building. At least 30 days after the
effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with
copies of the instrument effecting any of the foregoing Transfers and
documentation establishing Tenant's satisfaction of the requirements set forth
above applicable to any such Transfer. The occurrence of a Permitted Transfer
shall not waive Landlord's rights as to any subsequent Transfers. "TANGIBLE NET
WORTH" means the excess of total assets over total liabilities, in each case as
determined in accordance with generally accepted accounting principles
consistently applied ("GAAP"), excluding, however, from the determination of
total assets all assets which would be classified as intangible assets under
GAAP including, without limitation, goodwill, licenses, patents, trademarks,
trade names, copyrights, and franchises. Any subsequent Transfer by a Permitted
Transferee shall be subject to Landlord's prior written consent (which Landlord
may grant or deny in its sole discretion).

      11. INSURANCE; WAIVERS; SUBROGATION; INDEMNITY

            (a) TENANT'S INSURANCE. Tenant shall maintain throughout the Term
the following insurance policies: (1) commercial general liability insurance in
amounts of $3,000,000 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 (but only if such contractual liability insurance is not
already included in Tenant's commercial general liability insurance policy), (4)
worker's compensation insurance, containing a waiver of subrogation endorsement
acceptable to Landlord, 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 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.
<PAGE>   25
            (b) LANDLORD'S INSURANCE. Landlord shall carry throughout the Term
of this Lease fire and extended coverage insurance on the Building for at least
90% of the full replacement value.

            (c) 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 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.

            (d) INDEMNITY. Subject to Section 11.(c), 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 during the Term or any
holdover by Tenant or any person or entity deriving rights from Tenant beyond
the expiration of the Term (other than any Loss arising out of a breach of
Tenant's obligations under Section 25.(t), which shall be subject to the
indemnity in such section) except to the extent caused by the negligence or
fault of Landlord or its agents or (2) Tenant's failure to perform its
obligations under this Lease except to the extent caused 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
reasonably satisfactory to the indemnified party.

      12. 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. Provided
Tenant receives a Non-Disturbance Agreement from each such Mortgagee, Tenant
shall execute agreements confirming the subordination or superiority of this
Lease to any Mortgage upon Landlord or Landlord's Mortgagee's reasonable
request.
<PAGE>   26
            (b) ATTORNMENT. Provided Tenant receives a Non-Disturbance Agreement
from such party, 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.

            (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 unless such rent is actually received by
Landlord's Mortgagee; (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 Building 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
Building. 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 K. Landlord shall return a fully executed Subordination,
Non-Disturbance and Attornment Agreement in the form attached hereto as Exhibit
K, executed by Landlord and the Lender named therein to Tenant as soon as
reasonably possible. Landlord shall
<PAGE>   27
use reasonable efforts (which efforts shall not require the expenditure of funds
or the threat (or commencement) of litigation) to obtain a so-called
"nondisturbance agreement" from any future Landlord's Mortgagee in the form
attached hereto as Exhibit K or another form reasonably acceptable to Tenant and
such Landlord's Mortgagee or other institutional lenders (either the form
attached hereto as Exhibit K or such other reasonably acceptable form being
herein referred to as the "NON-DISTURBANCE AGREEMENT"). The subordination of
Tenant's rights hereunder to any future Landlord's Mortgagee under Section
12.(a) and the attornment of Tenant to any future Landlord Mortgagee under
Section 12.(b) shall be conditioned upon such future Landlord's Mortgagee's
execution and delivery of a Non-Disturbance Agreement.

      13. 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 are applicable to all tenants of the Building and 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.

      14. 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 180 days, then Tenant
may terminate this Lease as of the date of such Taking by giving written notice
to Landlord within 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.

            (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 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 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
14.(b).

            (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
<PAGE>   28
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.

      15. 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
Premises or 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 estimates that
the damage caused thereby cannot be repaired within two hundred ten (210) days
after the Casualty, then Tenant may terminate this Lease by delivering written
notice to Landlord of its election to terminate within 30 days after the Damage
Notice has been delivered to Tenant. If Tenant does not so timely terminate this
Lease, then (subject to Section 15.(c)) Landlord shall repair the Building or
the Premises, as the case may be, as provided below, and Rent for the portion of
the Premises 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, and Landlord makes a good faith determination that restoring the
Premises would be uneconomical, or if Landlord is required to pay 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 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.

            (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 the Premises and shall proceed
with reasonable diligence to restore the Building and Premises to substantially
the same condition as they 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. If the Premises are not substantially restored
within two hundred ten (210) days after a Casualty, Tenant shall have the right
to terminate this Lease upon at least sixty (60) days prior written notice;
provided, however, if Landlord substantially
<PAGE>   29
restores the Premises within said sixty-day period, Tenant's termination notice
shall be null and void and the provisions of this Lease shall remain in full
force and effect.

      16. 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.

      17. EVENTS OF DEFAULT. Each of the following occurrences shall be an
"EVENT OF DEFAULT":

            (a) Tenant's failure to pay Rent within five days after Landlord has
delivered 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 17.(a) on more than
one occasion during the twelve (12) month interval preceding such failure by
Tenant;

            (b) an Event of Default occurs under that certain Lease Agreement
dated January 31, 2000 by and between Landlord and Tenant with respect to the
premises known and numbered as 15 Elizabeth Drive, Chelmsford, Massachusetts
(the "15 ELIZABETH DRIVE LEASE");

            (c) Tenant abandons the Premises or any substantial portion thereof;

            (d) Tenant fails to comply with the Permitted Use set forth herein
and the continuance of such failure for a period of five (5) days after Landlord
has delivered to Tenant written notice thereof;

            (e) Tenant fails to provide any estoppel certificate within the time
period required under Section 25.(e) and such failure shall continue for five
days after written notice thereof from Landlord to Tenant;

            (f) 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 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
<PAGE>   30
continuously pursues such cure to completion within a period of not more than
seventy-five (75) days after the delivery of such notice; and

            (g) The filing of a petition by or against Tenant (the term "TENANT"
shall include, for the purpose of this Section 17.(g), 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
90 days after the filing thereof.

      18. 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 due under Section
19.(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, discounted to present value at
a per annum rate equal to the "Prime Rate" as published on the date this Lease
is terminated by The Wall Street Journal, Northeast Edition, in its listing of
"Money Rates," minus one percent, similarly discounted, minus (B) the then
present fair rental rate value of the Premises for such period;

            (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 19.(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 out-of-pocket 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 other portions of the Building. 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
<PAGE>   31
to dispossess or exclude Tenant from the Premises shall be deemed to be taken
under this Section 18.(b). If Landlord elects to proceed under this Section
18.(b), it may at any time elect to terminate this Lease under Section 18.(a);
or

            (c) Additionally, upon five (5) days prior written notice, 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 except as otherwise expressly provided herein; 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.

      19. 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 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 the state in which the Premises are located 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.

      20. 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>   32
      21. 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 14 and 15 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 or elsewhere in the Building by Tenant (but Tenant may not remove any
such item which was paid for, in whole or in part, by Landlord or any wiring or
cabling unless Landlord requires such removal). Additionally, at Landlord's
option, Tenant shall remove such alterations, additions, improvements, trade
fixtures, personal property, equipment, wiring, cabling, and furniture as
Landlord may request; however, Tenant shall not be required to remove any
addition or improvement to the Premises if Landlord has specifically agreed in
writing that the improvement or addition in question need not be removed. Tenant
shall repair all damage caused by such removal. All items not so removed shall,
at Landlord's option, 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;
any such disposition shall not be considered a strict foreclosure or other
exercise of Landlord's rights in respect of the security interest granted under
Section 20. The provisions of this Section 21 shall survive the end of the Term.

      22. 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 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 the
greater of (a) 150% of the daily Basic Rent payable during the last month of the
Term, or (b) 125% of the prevailing rental rate in the Building for similar
space. The provisions of this Section 22 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.

      23. 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
<PAGE>   33
any part thereof; to enter upon the Premises (after giving Tenant reasonable
notice thereof, which may be oral notice, except in cases of real or apparent
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; to change the name of the Building; and to
change the arrangement and location of entrances or passageways, doors, and
doorways, corridors, elevators, stairs, restrooms, or other public parts of the
Building;

            (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 12 months of the Term,
tenants.

      24. [INTENTIONALLY OMITTED]

      25. 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 arising after the date of transfer, 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.
<PAGE>   34
            (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 CRESA Partners, 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.

            (e) ESTOPPEL CERTIFICATES. From time to time, Tenant shall furnish
to any party designated by Landlord, within ten days after Landlord has made a
request therefor, a certificate signed by Tenant confirming and containing such
factual certifications and representations as to this Lease as Landlord may
reasonably request. Unless otherwise required by Landlord's Mortgagee or a
prospective purchaser or mortgagee of the Building, the initial form of estoppel
certificate to be signed by Tenant is attached hereto as Exhibit F.

            (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 in the Basic Lease
Information, (2) hand delivered to the intended address, (3) sent by a
nationally recognized overnight courier service, or (4) sent by facsimile
transmission during normal business hours followed by a confirmatory letter sent
in another manner permitted hereunder. 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 unless such waiver is
in writing signed by Landlord, 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 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
<PAGE>   35
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.

            (k) NO OFFER. The submission of this Lease to Tenant shall not be
construed as an offer, and Tenant shall not have any rights under this Lease
unless Landlord executes a copy of this Lease and delivers it to Tenant.

            (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.

            (p) FINANCIAL REPORTS. Within 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. If Tenant is a publicly
traded corporation, Tenant may satisfy its obligations hereunder by providing to
Landlord Tenant's most recent annual and quarterly reports. 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 (3) if required by court order.
Tenant shall not be required to deliver the financial statements required under
this Section 25.(p) more than once in any 12-month
<PAGE>   36
period unless requested by Landlord's Mortgagee or a prospective buyer or lender
of the Building or an Event of Default occurs.

            (q) LANDLORD'S FEES. Whenever Tenant requests Landlord to take any
action not required of it hereunder or give any consent required or permitted
under this Lease, Tenant will reimburse Landlord for Landlord's reasonable
out-of-pocket costs payable to third parties and incurred by Landlord in
reviewing the proposed action or consent, including without limitation
reasonable attorneys', engineers' or architects' fees, within ten 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.

            (r) TELECOMMUNICATIONS. Tenant and its telecommunications companies,
including but not limited to local exchange telecommunications companies and
alternative access vendor services companies shall have no right of access to
and within the Building, for the installation and operation of
telecommunications systems including but not limited to voice, video, data, and
any other telecommunications services provided over wire, fiber optic,
microwave, wireless, and any other transmission systems, for part or all of
Tenant's telecommunications within the Building and from the Building to any
other location without Landlord's prior written consent (which consent shall not
be unreasonably withheld or delayed). Notwithstanding any provisions of this
Section 25.(r) to the contrary, and provided Tenant obtains Landlord's prior
written consent as aforesaid, Tenant may make or perform certain installations
affecting Tenant's telecommunications systems provided that: (i) any such
installations only affect the Premises; (ii) no such installations affect any of
the Building HVAC, mechanical, electrical or plumbing systems; (iii) Tenant
shall promptly repair and restore any damage caused by any such installation;
and (iv) upon Landlord's request, at the earlier termination or expiration of
this Lease, Tenant shall restore the Premises to the condition that existed on
the date of this Lease.

            (s) CONFIDENTIALITY. Tenant acknowledges that the terms and
conditions of this Lease are to remain confidential for Landlord's benefit, and
may not be disclosed by Tenant to anyone, by any manner or means, directly or
indirectly, without Landlord's prior written consent. The consent by Landlord to
any disclosures shall not be deemed to be a waiver on the part of Landlord of
any prohibition against any future disclosure.

            (t) HAZARDOUS MATERIALS. The term "HAZARDOUS MATERIALS" means any
substance, material, or waste which is now or hereafter classified or considered
to be hazardous, toxic, or dangerous under any Law relating to pollution or the
protection or regulation of human health, natural resources or the environment,
or poses or threatens to pose a hazard to the health or safety of persons on the
Premises or in the Building. Tenant shall not use, generate, store, or dispose
of, or permit the use, generation, storage or disposal of Hazardous Materials on
or about the Premises or the Building except in a manner and quantity necessary
for the ordinary performance of Tenant's business, and then in compliance with
all Laws. If Tenant breaches its obligations under this
<PAGE>   37
Section 25.(t), Landlord may immediately take any and all action reasonably
appropriate to remedy the same, including taking all appropriate action to clean
up or remediate any contamination resulting from Tenant's use, generation,
storage or disposal of Hazardous Materials. Tenant shall defend, indemnify, and
hold harmless Landlord and its representatives and agents from and against any
and all claims, demands, liabilities, causes of action, suits, judgments,
damages and expenses (including reasonable attorneys' fees and cost of clean up
and remediation) arising from Tenant's failure to comply with the provisions of
this Section 25.(t). This indemnity provision shall survive termination or
expiration of the Lease.

            (v) TIME OF ESSENCE. Time is of the essence of this Lease and each
and all of its provisions.

            (w) SIGNAGE. Tenant may install, at Tenant's risk and expense, one
(1) sign on the exterior facade of the Building, one (1) sign (4 feet x 4 feet)
on the ground in front of the main entrance of the Building, and one (1) company
identification/directional sign in the same location as the existing company
identification/directional sign and at a size no bigger than such existing sign,
in accordance with all Laws and subject to Landlord's prior approval and
consent, which approval and consent shall not be unreasonably withheld,
conditioned or delayed.

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

            (y) FAILURE OF TENANT TO CONTINUOUSLY OCCUPY THE PREMISES. If, for
more than one hundred eighty (180) consecutive days or more than one hundred
eighty (180) days in a three hundred sixty-five (365) day period, Tenant (1)
vacates the Premises or (2) fails to continuously operate its business therein,
Landlord may terminate the Lease upon giving written notice to Tenant as of the
date specified in such notice. If Landlord
<PAGE>   38
terminates this Lease, then this Lease shall terminate and neither party shall
have any further obligations hereunder as of the terminate date except as
otherwise provided herein and Tenant shall pay to Landlord all Rent accrued
through the termination date. Thereafter, Landlord may lease the Premises (or
any portion thereof) to any person without liability to Tenant.

            (z) 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. The Rooftop Equipment shall be used only by
Tenant. Before installing the Rooftop Equipment, Tenant shall submit to Landlord
for its approval (which approval shall not be unreasonably withheld, conditioned
or delayed to the extent such plans and specifications do not reflect
alterations which affect the exterior or structure of the Building or its HVAC,
plumbing or mechanical systems or its base building electrical system) 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, regulations,
restrictions (governmental or otherwise) and architectural guidelines in effect
for the area in which the Building is located as they may be amended from time
to time (the "LEGAL REQUIREMENTS"). 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, Tenant
shall install (in a good and workmanlike manner), maintain and use the Rooftop
Equipment in accordance with all Legal Requirements 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 and operate and maintain the Rooftop
Equipment in such a manner so as not to unreasonably interfere with any
equipment (including any other satellite, antennae, or other transmission
facility) on the Building's roof or in the Building. Landlord may require that
Tenant screen the Rooftop Equipment with a parapet or other screening device
reasonably 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, unless said relocation is requested
because the Rooftop Equipment is unreasonably interfering with other equipment
on the Building's roof or in the Building (in which case Tenant shall pay for
the cost of such relocation). Upon Landlord's written request (but not
otherwise), 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:
<PAGE>   39
(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.

            (aa) NOTICE OF LEASE. Tenant agrees not to record this Lease and,
subject to the provisions of Section 25.(s) above, to keep the terms of this
Lease confidential, but each party hereto agrees, at the request of the others
to execute a so-called Notice of Lease in recordable form complying with
applicable law and reasonably satisfactory to Landlord's attorneys. In no event
shall such document set forth the Rent or other charges payable by Tenant
hereunder.

            (bb) LANDLORD'S AUTHORITY, ETC. Landlord represents and warrants
that (i) it is the record owner of the Premises in fee simple, (ii) it has full
right and authority to execute this Lease, and (iii) this Lease does not
conflict with any other agreement to which Landlord is bound.

            (cc) FIBER OPTIC LINES. Subject to the provisions of Section 8
above, Tenant, at its sole cost and expense and with Landlord's prior written
consent (which consent shall not be unreasonably withheld or delayed), may
install underground fiber optic lines within the Premises. Notwithstanding any
provisions of this Section 25.(cc) to the contrary, Landlord shall not be deemed
to have unreasonably withheld its consent to any installation that would affect
the Building's structure or its HVAC, plumbing, electrical, or mechanical
systems. Tenant shall promptly repair and restore any damage caused by any such
installation and, upon Landlord's request, at the earlier termination or
expiration of this Lease, Tenant shall restore the Premises to the condition
that existed on the date of this Lease. Any and all such installations of fiber
optic lines shall comply with all applicable Laws.

      26. OTHER PROVISIONS. LANDLORD AND TENANT EXPRESSLY DISCLAIM ANY IMPLIED
WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANT'S INTENDED COMMERCIAL
PURPOSE, AND, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, TENANT'S OBLIGATION
TO PAY RENT HEREUNDER IS NOT DEPENDENT UPON THE CONDITION OF THE PREMISES OR THE

                                    EXHIBIT D

                          TENANT FINISH-WORK: ALLOWANCE

      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.
Notwithstanding the foregoing sentence, Landlord shall, at its sole cost and
expense, perform the following: (a) replace the landscape timbers as necessary;
(b) repair the sidewalk in front of the main entrance to the Building; and (c)
recaulk and reseal the Building. Further, and subject to the provisions of this
Section 1, Landlord agrees to pay to replace the four (4) rooftop HVAC units
known as units 4, 8, 9 and 12 and to repair the other existing HVAC rooftop
units in accordance with the specifications attached hereto as Exhibit D-1
(collectively, the "HVAC REPLACEMENT/REPAIR SPECIFICATIONS"). Landlord intends
to bid out the repair work enumerated in the HVAC Replacement/Repair
Specifications and to pay to Tenant, in accordance with the provisions of this
Section 1, the sum that would be required to be paid to the lowest bidder (the
"HVAC REPAIR ALLOWANCE") to perform such work. Tenant desires to have Thermo
Engineering, Inc. perform the work enumerated in the HVAC Replacement/Repair
Specifications, and shall be responsible for ensuring that Thermo Engineering,
Inc. performs such work in accordance with said Specifications. After completion
of such work in accordance with the HVAC Replacement/Repair Specifications,
Landlord shall pay to Tenant the HVAC Repair Allowance within twenty (20)
business days from Tenant's written request for the same provided that: (a)
Tenant shall not be in default under the Lease; (b) the Lease shall be in full
force and effect; and (c) Tenant has provided Landlord with evidence reasonably
satisfactory to Landlord that the work enumerated in the HVAC Replacement/Repair
Specifications have been completed in accordance with said Specifications.

      2. 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, delayed or conditioned), of all
alterations, improvements and installations that Tenant proposes to construct,
install and complete 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 alterations, improvements and installations 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 or disapproval, as the case may be, of the final working
drawings (inclusive of any approval required by the Building's engineer of
record) shall be completed within ten (10) business days of Landlord's receipt
of such working drawings. If Landlord disapproves the final working drawings,
Landlord shall specify the reasons for such disapproval in writing to Tenant.
Landlord's approval of such working drawings shall not be unreasonably withheld,
delayed or conditioned, provided that (a) they comply with all applicable laws,
rules, and regulations, (b) such working drawings are sufficiently detailed to
allow construction of the alterations, improvements and installations in a good
<PAGE>   47
and workmanlike manner, (c) the alterations, improvements and installations
depicted thereon conform to the rules and regulations promulgated from time to
time by Landlord for the construction of tenant alterations, improvements and
installations (a copy of which has been delivered to Tenant), and (d) the
alterations, improvements and installations do not affect the Building's
Structure or any of its HVAC, electrical, mechanical or plumbing systems. 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 alterations, improvements and installations to be
constructed in accordance with and as indicated on the Working Drawings.
Landlord's approval of the Working Drawings shall not be a representation or
warranty of Landlord that such drawings 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 (which approval shall not be withheld, delayed or conditioned), 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.

      3. The Work shall be performed only by contractors and subcontractors
approved in writing by Landlord, which approval shall not be unreasonably
withheld or delayed. 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 and
delivery of the Premises to Tenant, 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, and shall be performed in such a
manner and at such times as not to interfere with or delay Landlord's other
contractors, the operation of the Building, and the occupancy thereof by other
tenants. 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.).

      4. 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.

      5. 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.
<PAGE>   48
      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, or a portion of the Work, shall be, in
Landlord's reasonable discretion, substantially complete; (iv) Tenant shall
furnish to Landlord: (A) if the entire Work is substantially complete, 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,
or in the case of completion of a portion of the Work, have been paid and that
no lien exists of record with respect thereto; and (v) Tenant shall not request
any portion of the Construction Allowance more than once a month. 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.

      6. 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 and approve the Working Drawings and/or any drafts and/or
modifications thereto and to review the construction of the Work.

                                 RENEWAL OPTION

      Provided no Event of Default exists and Tenant is occupying the entire
Premises at the time of such election, Tenant may renew this Lease for one
additional period of five (5) years, by delivering written notice of the
exercise thereof to Landlord not earlier than fifteen (15) months nor later than
twelve (12) months before the expiration of the Term. The Basic Rent payable for
each month during such extended Term shall be the prevailing rental rate (the
"PREVAILING RENTAL RATE"), at the commencement of such extended Term, for
renewals of 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. Within thirty (30) days after receipt of Tenant's notice to renew,
Landlord shall deliver to Tenant written notice of the Prevailing Rental Rate
and shall advise Tenant of the required adjustment to Basic Rent, if any, and
the other terms and conditions offered. Tenant shall, within ten (10) days after
receipt of Landlord's notice, notify Landlord in writing whether Tenant accepts
or rejects Landlord's determination of the Prevailing Rental Rate. If Tenant
timely notifies Landlord that Tenant accepts Landlord's determination of the
Prevailing Rental Rate (and failure of Tenant to notify Landlord within the time
period prescribed above shall be deemed acceptance) or if, after a timely
rejection by Tenant of such determination, the Prevailing Rental Rate is
determined according to the procedures set forth in this Exhibit, then, on or
before the commencement date of the extended Term, 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) Basic Rent shall be adjusted to the Prevailing Rental Rate;

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

            (c) Landlord shall lease to Tenant the Premises in their
      then-current condition, and Landlord shall not provide to Tenant any
      allowances (e.g., moving allowance, construction allowance, and the like)
      or other tenant inducements.

If Tenant rejects Landlord's determination of the Prevailing Rental Rate, Tenant
may, but only within ten (10) days after receipt of Landlord's notice, require
by written notice to Landlord that the determination of Prevailing Rental Rates
be made by brokers. In such event, within ten (10) days thereafter, each party
shall select a qualified commercial real estate broker with at least ten (10)
years experience in appraising property and buildings in the city or submarket
in which the Premises are located. The two brokers shall give their opinion of
Prevailing Rental Rates within ten (10) days after their retention. In the event
the opinions of the two brokers differ and, after good faith efforts over the
succeeding ten (10) day period, they cannot mutually agree, the brokers shall
immediately and jointly appoint a third broker with the qualifications specified
above. This third broker shall immediately (within five (5) days) choose either
the determination of
<PAGE>   57
Landlord's broker or Tenant's broker and such choice of this third broker shall
be final and binding on Landlord and Tenant. Each party shall pay its own costs
for its real estate broker. The parties shall equally share the costs of any
third broker. The parties shall immediately confirm the renewal term, Basic Rent
and the other terms and conditions so determined, in writing.

      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 any portion of the Premises, (3)
Tenant fails to timely exercise its option under this Exhibit, time being of the
essence with respect to Tenant's exercise thereof, or (4) Landlord determines,
in its sole but reasonable discretion, that Tenant's financial condition or
creditworthiness has materially deteriorated since the date of this Lease.

                            RENT ABATEMENT PROVISIONS

      Basic Rent shall be conditionally abated during the first three (3) months
of the Term. Commencing with the fourth (4th) month of the Term, Tenant shall
make Basic Rent payments as otherwise provided in the Lease. Notwithstanding
such abatement of Basic Rent (a) all other sums due under the Lease, including
Additional Rent and Tenant's share of Taxes shall be payable as provided in the
Lease, and (b) any increases in Basic Rent set forth in the Lease shall occur on
the dates scheduled therefor.

      The abatement of Basic Rent provided for in this Exhibit is conditioned
upon Tenant's full and timely performance of all of its obligations under the
Lease. If at any time during the Term an Event of Default by Tenant occurs, then
the abatement of Basic Rent provided for in this Exhibit shall immediately
become void, and Tenant shall promptly pay to Landlord, in addition to all other
amounts due to Landlord under this Lease, the full amount of all Basic Rent
herein abated.

             SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT

      This AGREEMENT is made and entered into as of ___________________, 2000,
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 Brooks
Automation, Inc.
("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
31, 2000 (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 beyond any applicable grace periods under any
provision of the Lease or this Agreement 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. Without limiting the foregoing, and so long as the foregoing
conditions are met, Lender
<PAGE>   65
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.

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.
<PAGE>   66
      6. REPRESENTATIONS AND WARRANTIES.

            6.1 Joint and Several. Landlord and Tenant hereby jointly and
severally 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 April 1, 2000.

      (c) Under the Lease, Tenant shall be obligated to pay rent without present
right of defense or offset, at the rate of $68,680.98 per month commencing July
1, 2000. Rent is paid through and including N/A , 2000. 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 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>   67
      (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.

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
<PAGE>   68
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
after having been mailed by registered or certified mail, return receipt
requested, or by express mail, in any event with sufficient postage affixed, and

Such addresses may be changed by notice pursuant to this Paragraph 11; but
notice of change of address is effective only upon receipt. Landlord and Tenant
jointly and severally agree that they will furnish Lender with copies of all
notices relating to the Lease. All communications to Lender shall reference
"AMRESCO Loan No.: __________ ".

      12. SUCCESSORS AND ASSIGNS. As used in this Agreement, the word "Tenant"
shall mean Tenant and any subsequent holder or holders of an interest under the
Lease, as the text may require, provided that the interest of such holder is
acquired in accordance with the terms and provisions of the Lease and the word
"Lender" shall mean Lender or any other subsequent holder or holders of the
Mortgage or any party acquiring title to the Demised Premises by purchase at a
foreclosure sale, by deed of the Lender, or otherwise. Subject to the foregoing,
this Agreement shall bind and inure to the benefit of Landlord, Tenant and
Lender, their legal representatives, successors and assigns. The terms Lease,
Mortgage and Lease Assignment shall include any and all amendments,
modifications, replacements, substitutions, extensions, renewals and supplements
thereto.

      13. FURTHER ASSURANCES. Landlord and Tenant from time to time shall
execute and deliver at Lender's request all instruments that may be necessary or
appropriate to evidence their agreement hereunder provided such instrument
neither increases Tenant's obligations or decreases its rights under the Lease.

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

      15. SEVERABILITY. A determination that any provision of this Agreement is
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.
