ITEM 1.   BUSINESS

  GENERAL

     Lifeline Systems, Inc. (the "Company") provides 24-hour personal response
  monitoring services to its subscribers, primarily elderly individuals with
  medical or age-related conditions as well as physically challenged
  individuals. These subscribers communicate with the Company through products
  designed, manufactured and marketed by the Company, consisting principally of
  a communicator which connects to the telephone line in the subscriber's home
  and a personal help button, which is worn or carried by the individual
  subscriber and which, when activated, initiates a telephone call from the
  subscriber's communicator to the Company's central monitoring facilities. The
  Company believes it is a major provider of such services.

  BUSINESS DEVELOPMENTS

     In November, 1997, the Company entered into a ten-year lease for an 84,000
  square foot facility in Framingham, MA which will serve as its corporate
  headquarters. The Company intends to move from its current headquarters to
  this facility in late 1998. Annual rental payments under the lease approximate
  $775,000. The lease contains two five-year options to renew at the end of the
  initial lease term. The Company is currently evaluating possible alternatives
  to minimize the remaining obligations under its existing lease.

     In December, 1997, the Company announced a one-time reorganization charge
  of approximately $4.3 million, or $0.43 per diluted share on an after-tax
  basis, to account for its approximately $11 million investment in technology
  for a new call center platform, the relocation of the Company's corporate
  headquarters from its current Cambridge, MA facility to a new facility in
  Framingham, MA, and other initiatives to lower operating costs. The
  reorganization charge reflected costs associated with decommissioning the
  current call center system, rental commitments and other costs associated with
  its current facility, employee severance and benefits, and the write down of
  impaired goodwill.

  INDUSTRY SEGMENTS

     The Company operates in one industry segment. Its operations consist of
  providing personal response services associated with those products it
  designs, manufactures, and markets. Foreign revenues, from Canada, comprised
  less than 10% of the Company's total revenues in 1997, and the Company has no
  significant tangible assets in foreign countries.

  THE LIFELINE SERVICE

     The Company's principal offering, called LIFELINE(R), consists of a
  monitoring service utilizing equipment manufactured by the Company. The
  Company's monitoring service is a personal response service which provides 24-
  hour monitoring and personalized support to elderly individuals with medical
  or age-related conditions and to physically challenged individuals throughout
  the United States and Canada. Through use of the LIFELINE service, individuals
  in need of help are able to signal monitoring personnel in one of the
  Company's response centers. These trained monitors identify the nature and
  extent of the

                                      -2-

<PAGE>
 
  subscriber's particular need and manage the situation by notifying the
  subscriber's friends, neighbors, and/or emergency personnel, as set forth in a
  predetermined protocol established by the subscriber. The Company also offers
  a supportive home monitoring service which emphasizes social support for
  elderly individuals who live alone.

     The equipment used for the LIFELINE service includes a communicator, which
  connects to the telephone line in the subscriber's home and a personal help
  button, which is worn or carried by the individual subscriber. When pressed,
  the personal help button sends a radio signal to the communicator; the
  communicator automatically dials a response center where monitoring personnel
  answer the call and dispatch the designated responders, typically a friend or
  relative of the subscriber and/or emergency service, when help is needed. Most
  of the time, however, subscribers' calls require reassurance and support as a
  result of isolation or loneliness.

     The Company's primary monitoring center in Cambridge, Massachusetts is
  supported by its proprietary CORMIS software,. CORMIS receives incoming
  signals from subscribers' communicators, matches and retrieves the appropriate
  subscriber data records from a central database, and routes both the call and
  the data record to monitoring personnel in the Lifeline Response Center. The
  Company has made a significant investment in a new call center platform to
  replace CORMIS. This new call center platform is expected to become
  operational in late 1998.

     In the past, the Company offered its customers, typically healthcare
  providers which established their own Lifeline programs, two alternatives for
  providing the LIFELINE monitoring service: they could utilize the Lifeline
  Response Center to perform their monitoring or they could perform their own
  monitoring locally using equipment and software manufactured by the Company.
  Although the Company continues to service equipment for customers who perform
  their own monitoring, the Company no longer markets the equipment necessary
  for new providers to monitor their own subscribers. New providers outsource
  their monitoring activities to a Lifeline monitoring center to service their
  subscribers.

     Lifeline also provides its local programs with a comprehensive set of
  monitoring and business support services which reduce the program management
  responsibilities and administrative burden associated with a local monitoring
  center. In addition, the Company also provides the LIFELINE service directly
  to subscribers in the United States and to subscribers in Canada who do not
  have access to a local Lifeline program.

     The Company offers several versions of its communicators. All models
  currently available provide two-way voice communication over a speaker between
  the subscriber and the response center as well as other features. All of the
  Company's current models also offer the RSVP feature, which allows the
  subscriber to answer routine telephone calls by pushing the personal help
  button. The Company believes that the product line offers customers
  flexibility in terms of price and functionality.

  CUSTOMERS

     The Company primarily markets its services and products to hospitals,
  institutions, and other service providers in a variety of healthcare related
  fields. Hospitals, however, have historically been the Company's primary
  market. The Company believes that hospitals offer Lifeline's services and
  products to capture revenues from the sale of the service, improve healthcare
  for the communities they serve, enhance community relations, market other
  hospital services to the subscriber base, and/or contain healthcare costs by
  facilitating early discharge from the hospital and reducing the need for
  nursing home care.

                                      -3-
<PAGE>
 
  SALES AND MARKETING

     The Company sells its services and products through a direct sales
  organization in the United States and Canada.

     In support of the sales effort, the Company's sales professionals assist
  the Company's institutional customers in developing a marketing plan for the
  Lifeline program, monitoring progress against that plan, and providing
  training to the customer's staff on the management of their local Lifeline
  program. Programs' marketing plans typically address the introduction of
  Lifeline's services to key decision makers and service providers within the
  customer's organization; the planning and delivery of presentations to
  community responders such as police, fire, and medical emergency
  professionals; and the development of local referral networks of elder care
  and other service organizations to position the LIFELINE service as part of a
  continued care plan. Lifeline personnel also provide continuing operational
  support, ongoing consultation, and program evaluations.

  SOURCE OF RAW MATERIALS

     The Company manufactures all of its products, relying on outside vendors
  for components and enclosures. Any difficulties in obtaining these parts will
  have a direct effect on the Company's ability to meet shipment targets.
  Although the Company does generally have two or more suppliers for its
  proprietary components, it has no assurance that it will not encounter
  component shortages in the future, which may adversely affect the results of
  operations.

  PATENTS, LICENSES AND TRADEMARKS

     The Company considers its proprietary know-how with respect to the
  development, manufacture, and marketing of its personal response services to
  be a valuable asset. Due to rapid technological changes that characterize the
  industry, the Company believes that continued development of new services and
  products, the improvement of existing services and products, and patent and
  license protection are important in maintaining a competitive advantage.

     Although the Company owns numerous patents and patent applications in the
  United States, Canada, and other countries, the Company does not believe that
  its business as a whole is or will be materially dependent upon the protection
  afforded by its patents.

     The Company's LIFELINE trademark and servicemark are registered at the
  United States Patent and Trademark Office and in most states and some foreign
  countries. The Company also has a number of other trademarks.

  RESEARCH AND DEVELOPMENT

     Research and development continues to be an important strategic element for
  the Company and is geared toward enhancing and augmenting the Company's
  products and services. Research and development expenses were $1,709,000,
  $1,771,000, and $1,701,000, for the years ended December 31, 1997, 1996, and
  1995, respectively.

                                      -4-
<PAGE>
 
  BACKLOG/SEASONALITY

     Because of the nature of the Company's products, it endeavors to minimize
  the time which elapses from the receipt of a purchase order to the date of
  delivery of the products. Accordingly, the Company's backlog as of the end of
  any period represents only a portion of the Company's expected sales for the
  succeeding period and is not significant in understanding the Company's
  business. The Company does not believe that the industry in which it operates
  is seasonal.

  GOVERNMENT REGULATION

     The Company's products are registered with the Federal Communication
  Commission ("FCC") and comply with FCC regulations pertaining to radio
  frequency devices (Part 15) connected to the telephone system (Part 68). The
  Company has also received registrations of equipment from Canadian agencies.
  As new models are developed, they are submitted to appropriate agencies as
  required.

     The Company has registered its communicator products with the United States
  Food and Drug Administration.

     None of the Company's business is subject to renegotiation of profits or
  termination of contract by the government, nor is it impacted by any existing
  environmental laws.

  COMPETITION

     The Company believes that it is a major provider of personal response
  services and products. Other companies offer services and products competitive
  with those offered by the Company. These companies offer personal response
  services on a regional or national basis through both healthcare providers and
  directly to the subscribers themselves.

     Although price is a competitive factor, the Company believes that its
  customers' main considerations in choosing a personal response service are the
  high quality of service and product performance and reliability; customer
  support and service; and reputation and experience in the industry. The
  Company believes it competes favorably with respect to these factors.

  EMPLOYEES

     As of February 28, 1998 the Company employed approximately 535 full-time
  and permanent part-time employees. None of the Company's employees is
  represented by a collective bargaining unit, and the Company believes its
  relations with its employees are good.


ITEM 2.   PROPERTIES

     The Company leases a portion of a facility in Cambridge, Massachusetts
  which serves as its corporate headquarters including its manufacturing and
  U.S.-based monitoring operations. The lease includes two five-year options to
  renew at the end of the initial ten-year lease term. The Company leases
  facilities in other locations to support its field and Canadian operations.

                                      -5-

     In November, 1997, the Company entered into a ten-year lease for an 84,000
  square foot facility in Framingham, MA for its corporate headquarters. The
  Company intends to occupy this new facility in late 1998 and to vacate its
  Cambridge facility at that time. Annual rental payments under the lease
  approximate $775,000. The lease contains two five-year options to renew at the
  end of the initial lease term. The Company is currently evaluating possible
  alternatives for its existing lease.


ITEM 3.   LEGAL PROCEEDINGS

  The Company is not party to any material litigation.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

  None.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
          FINANCIAL CONDITION

This and other reports, proxy statements, and other communications to
stockholders, as well as oral statements by the Company's officers or its
agents, may contain forward-looking statements within the meaning of Section 21E
of the Securities Exchange Act of 1934, as amended, with respect to, among other
things, the Company's future revenues, operating income, or earnings per share.
Without limiting the foregoing, the words "believes," "anticipates," "plans,"
"expects," and similar expressions are intended to identify forward-looking
statements. There are a number of factors of which the Company is aware that may
cause the Company's actual results to vary materially from those forecast or
projected in any such forward-looking statement. These factors include, without
limitation, those set forth below under the caption "Certain Factors That May
Affect Future Results." The Company's failure to successfully address any of
these factors could have a material adverse effect on the Company's future
results of operations.

RESULTS OF OPERATIONS

1997 Compared with 1996

Total revenues for the year ended December 31, 1997 were $57.0 million, an
increase of 14% compared with the $50.2 million recorded in 1996.

Service revenues grew to $32.0 million of the Company's total revenues for the
year ended December 31, 1997, compared to $24.2 million for the prior year.
Service revenues comprised 56% of the Company's total revenues in 1997 up from
48% in 1996. This increase in revenue reflects the continued success of the
Company's strategy to focus on subscriber growth and recurring service revenues.
As a result, there was a 26% growth in the number of subscribers the Company
monitored to approximately 196,000 at December 31, 1997 from approximately
156,000 at December 31, 1996. The increase in subscribers continues to be driven
principally by conversions of locally-monitored programs to centralized
monitoring provided by the Lifeline Response Center and growth of the Company's
existing programs. The increase in service revenues was also favorably impacted
by the Company's strategy of packaging products and services into a single
service offering, which resulted in higher per-subscriber service revenue. The
Company's ability to sustain the current level of service revenue growth depends
on its ability to expand the market for its personal response services and
convert additional locally-monitored programs to monitoring service provided
directly by Lifeline. The Company believes that the high quality of its services
and its commitment to providing caring and rapid response to the at-risk elderly
and physically challenged will be a factor in meeting this challenge.

Net product revenues totaled $23.8 million during 1997, representing a 4%
decrease over net product revenues in 1996 of $24.9 million. The decrease in
1997 was a result of the decline in the average selling price from 1996 levels
because of a change in product mix sold to lower priced products coupled with
volume discounts. In January, 1997, the Company introduced the Classic
Pendant(TM), a new personal help button designed with particular emphasis on its
fashion appeal. This new button did not have a material impact on 1997 product
revenue. The Company expects continued declining product sales in future periods
as it continues with the strategy of packaging products and services into a
single service offering.

Finance and rental income, representing income earned from the Company's
portfolio of sales-type leases, was consistent in 1997 with the $1.1 million
recorded in the previous year. While customers continue to take advantage of the
Company's leasing program, there was an unusually high number of leases expiring
during the year ended December 31, 1996 that resulted in higher rental income in
the prior year. Rental income is derived from the short-term rental of equipment
from expired leases until such time the equipment is returned to the

                                     -10-
<PAGE>
 
Company. The decline in rental income in 1997 was offset in part by an increase
in finance income from leases maintained in the Company's portfolio which led to
the consistent level achieved. The Company believes that the retention of new
leases in its own portfolio will increase finance income in future years.

Cost of services, as a percentage of service revenues, increased to 47% for the
year ended December 31, 1997 from 42% for the year ended December 31, 1996. The
Company's continued investment in personnel and systems enhancements in support
of its current service infrastructure has resulted in higher cost of services in
1997. These expenditures have enabled the Company to continue to provide a high
level of service to its increasing subscriber base. As the Company grows its
subscriber base and further develops its monitoring capabilities, it continues
to make capital expenditures on a new response center platform at its corporate
headquarters. Total expenditures for the Company's information systems
infrastructure at its primary monitoring facility are expected to be
approximately $11 million, of which approximately $7.5 million was expended
during 1997. These expenditures did not have an impact on 1997 results of
operations since the platform is expected to be placed in service in late 1998.
However, cost of services in future years is expected to be impacted by the
depreciation of these investments.

For the year ended December 31, 1997, cost of product sales as a percentage of
product sales was 28%, versus 33% in the prior year. The improvement is largely
attributable to continued utilization of new technology which reduced material
costs, improvements in manufacturing processes, and the enhanced reliability of
the Company's product which reduced the warranty costs compared to 1996 levels.

Selling, general, and administrative expenses as a percentage of total revenues
improved to 45% for the year ended December 31, 1997 from 47% for the year ended
December 31, 1996. The $2.0 million increase in actual expenses year-over-year
was primarily attributable to the Company's larger employee base in 1997. This
resulted in an increase in salaries and related fringe benefits as compared to
the year ended December 31, 1996. Also, increased spending associated with the
Company's employee recruitment efforts, higher operating costs for the Company's
corporate headquarters, enhancements related to information systems, and the
inclusion of a full year of costs associated with the July, 1996 acquisition of
CareTel, Inc. of Ontario, Canada attributed to the overall increased spending in
1997.

Research and development expenses represented 3% of revenues in 1997 versus 4%
in 1996. Research and development efforts are focused on ongoing product
improvements, and the Company expects to maintain these expenses, as a
percentage of total revenues, at a relatively consistent level.

In December, 1997, the Company announced a one-time reorganization charge of
approximately $4.3 million, or $0.43 per diluted share on an after-tax basis to
account for its approximately $11 million investment in technology for a new
call center platform, the relocation of the Company's corporate headquarters
from its current Cambridge, MA facility to a new facility in Framingham, MA, and
other initiatives to lower operating costs. As a result, the Company incurred a
$4.3 million pre-tax charge to operations for the year ended December 31, 1997.
The charge covered $304,000 of costs associated with the write down to fair
value of certain call center fixed assets, $1.2 million of costs for the write-
down to fair value of certain leasehold improvements and lease commitments on
its current facility, $150,000 of costs associated with the write down to fair
value of equipment made obsolete from prior years' acquisitions, $842,000 of
costs for employee severance and related benefits, and $1.8 million for the
write down of impaired goodwill.

                                     -11-

<PAGE>
 
The Company's effective tax rate was 41.4% for 1997, as compared to 41% in 1996.
The increase in the Company's rate was largely attributable to the
nondeductibility of the write down of the Canadian portion of goodwill and a
higher Canadian tax rate.

1996 Compared with 1995

Total revenues for the year ended December 31, 1996 were $50.2 million, an
increase of 16% compared with the $43.4 million recorded in 1995.

Service revenues represented $24.2 million of the Company's total revenues for
the year ended December 31, 1996, compared to $18.6 million for the prior year.
This 30% increase in service revenues was driven primarily by a 30% increase in
subscribers, to approximately 156,000 at December 31, 1996, from nearly 120,000
at the end of 1995. Service revenues comprised 48% of the Company's total
revenues in 1996 compared to 43% in 1995 which was consistent with the Company's
continued transition to a service-oriented business, with its focus on
developing its base of subscribers and generating recurring service revenues.
The increase in subscribers in 1996 was driven by conversions of locally-
monitored programs to centralized monitoring by the Company, growth of the
Company's existing programs, and by the Company's acquisition of CareTel, Inc.
in July, 1996 which contributed nearly 3,000 subscribers.

Net product revenues totaled $24.9 million during 1996, representing a 6%
increase over product revenues in 1995 of $23.4 million. The 1996 results
benefited from an entire year of sales of the CarePartner(TM) line, the first
models of which were introduced in September, 1995. The increase in volume
attributed to this line was partially offset by a decline in the average selling
price. The average selling price decreased because of product and service price
offerings in support of the Company's strategy to grow recurring service revenue
while maintaining product sales. The Company introduced the CarePartner
Telephone(TM) during the third quarter of 1996, which replaced the Company's
CommuniCatorPlus(TM). This version of the Company's full-function speaker
telephone incorporates digital speech technology, called VoiceAssist(TM), which
provides special features for those with visual or hearing limitations,
clarifies alarm messages, and instructs users in a friendly, reassuring manner.
This product did not have a material impact on 1996 product revenues.

Finance and rental income, representing income earned from the Company's
portfolio of sales-type leases, decreased $.2 million to $1.1 million in 1996
from $1.3 million in 1995. The decline was attributable to the overall aging of
the lease portfolio existing when the Company transitioned to an arrangement
with a third-party leasing agent, beginning in January, 1994. Although this
arrangement provided cash flow benefits during 1994 and 1995, in January, 1996
the Company terminated this arrangement and introduced a more customer-focused,
internally managed and funded leasing program.

Cost of services, as a percentage of service revenues, increased to 42% for the
year ended December 31, 1996 from 40% for the year ended December 31, 1995. The
increased cost was attributable to the Company's investment in personnel and
systems supporting its growing service infrastructure. As the Company grows its
subscriber base and develops its monitoring capabilities, it expects to continue
to invest in its service infrastructure to enhance its ability to provide caring
service for its subscribers. These investments are expected to be directed
primarily toward systems enhancements and improvements.

For the year ended December 31, 1996, cost of product sales as a percentage of
product sales was 33%, versus 36% in the prior year. This decrease was due
largely to improvements in manufacturing processes and the application of new
technology which reduced product costs.

                                     -12-

<PAGE>
 
Selling, general, and administrative expenses as a percentage of revenues
decreased slightly to 47% for the year ended December 31, 1996 from 48% for the
year ended December 31, 1995. The dollar increase in actual expenses to $23.9
million in 1996 from $21.0 million in 1995 was largely attributable to
expenditures related to enhancements to information systems, salaries, and
related fringe benefits due to the overall increase of the Company's employee
base; market development and promotional strategies aimed at the healthcare
channel and related referral networks; and the additional administrative
expenses associated with the acquisition of CareTel, Inc. in the third quarter
of 1996.

Research and development expenses represented 4% of revenues in 1996 and in
1995. Research and development efforts are focused on ongoing product
improvements.

The Company's effective tax rate was 41% for 1996, as compared to 43% in 1995.
The reduction in the Company's rate was largely due to the impact of tax-exempt
income from the Company's marketable securities portfolio and utilization of a
subsidiary with favorable tax status.

LIQUIDITY AND CAPITAL RESOURCES

During the year ended December 31, 1997, the Company's portfolio of cash, cash
equivalents, and investments decreased $5.4 million to $7.9 million at December
31, 1997 from $13.3 million at December 31, 1996. The net decrease resulted from
continued expenditures for the Company's information systems infrastructure. The
Company anticipates it will spend approximately $11.0 million as it develops a
flexible, scaleable, and fault tolerant response center platform at its primary
monitoring facility to support its growing subscriber base. While the new
platform will be placed in service after 1997, approximately $7.5 million was
expended during 1997, principally pursuant to development agreements entered
into with third party vendors. In addition, the Company used $1.6 million, net
of cash received on leases, to fund its internal leasing program, as compared to
$1.2 million in 1996, and a generation of $2.9 million of cash in 1995 from
payments received from the Company's existing portfolio of sales-type leases.
Also, during 1997 the Company invested $2.8 million in equipment purchases for
use in the development and manufacture of its products and services, as well as
for Company-owned equipment provided directly to customers under comprehensive
service agreements and to subscribers not serviced by local Lifeline programs.
Total expenditures were offset, in part, by the Company's profitable operations
in 1997.

In November, 1997, the Company entered into a ten-year lease for an 84,000
square foot facility in Framingham, MA for its corporate headquarters. The
Company intends to occupy this new facility in late 1998. Annual rental payments
under the lease approximate $775,000. The lease contains two five-year options
to renew at the end of the initial lease term. The Company is currently
evaluating possible alternatives for its existing lease. The Company expects
that it will incur capital expenditures associated with the move.

In January, 1997, the Company's Board of Directors approved the repurchase of up
to 100,000 shares of the Company's common stock from time to time in the open
market for general corporate purposes. The Company purchased 60,700 shares
directly from its Chief Executive Officer during 1997 for $1.1 million as part
of this program. These shares were purchased from the Chief Executive Officer
partly in connection with the repayment of a $250,000 note receivable and
associated tax expenses.

In November, 1995, the Company secured a $4.0 million line of credit effective
in January, 1996. During 1997, the term of the credit facility was extended
until March, 1998. This credit agreement contains a number of covenants,
including requirements that the Company maintain certain levels of financial
performance and capital structure, limitations on the Company's capital and
other expenditures, and restrictions on the 

                                      -13-
<PAGE>
 
Company's capacity to secure additional debt financing. No amounts were
outstanding as of December 31, 1997. The Company is currently in the process of
renegotiating a new line of credit.

The Company expects that funding requirements for operations and in support of
future growth are expected to be met primarily from operating cash flow and
existing cash and marketable securities. The Company expects these sources will
be sufficient to finance the cash needs of the Company through 1998 including
the continued investment in its new response center platform, the 1998 move to
new corporate headquarters, the 1998 requirements of its internally funded lease
financing program and stock repurchases, any potential acquisitions, and other
investments in support of its current business.

In June, 1997 the Financial Accounting Standards Board issued Statement No. 130
("SFAS" 130), "Reporting Comprehensive Income." SFAS 130 requires changes in
comprehensive income to be shown in a financial statement that is displayed with
the same prominence as other financial statements. While not mandating a
specific financial statement format, SFAS 130 requires that an amount
representing total comprehensive income be reported. SFAS 130 will become
effective for fiscal years beginning after December 15, 1997. Reclassification
of financial statements for earlier periods is required for comparative
purposes. The Company does not believe that the adoption of SFAS 130 will have a
material impact on results of operations.

In June, 1997, the Financial Accounting Standards Board issued Statement No. 131
("SFAS" 131), "Disclosures about Segments of an Enterprise and Related
Information." SFAS 131, which supersedes Statement No. 14, "Financial Reporting
for Segments of a Business Enterprise," changes the way public companies report
information about segments. SFAS 131, which is based on the management approach
to segment reporting, includes requirements to report segment information
quarterly and entity-wide disclosures about products and services, major
customers, and the material countries in which the entity holds assets and
reports revenues. SFAS 131 is effective for fiscal years beginning after
December 15, 1997. Restatement for earlier years is required for comparative
purposes unless impracticable. In addition, SFAS 131 need not be applied to
interim periods in the initial year; however, in subsequent years, interim
period information must be presented on a comparative basis. The Company does
not believe that the adoption of SFAS 131 will have a material impact on
financial statement disclosures.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

The following important factors, among others, could cause actual results to
differ materially from those indicated by forward-looking statements made in
this Annual Report on Form 10-K and presented elsewhere by management from time
to time.

The Company's results are partially dependent on its ability to develop services
and products that keep pace with continuing technological changes, evolving
industry standards, changing subscriber preferences and new service and product
introductions by the Company's competitors. Lifeline's future success will
depend on its ability to enhance its existing services and products (including
accessories), to introduce new service and product offerings to meet and adapt
to changing customer requirements and emerging technologies on a timely basis
and to offer such products and services at competitive prices. There can be no
assurance that Lifeline will be successful in identifying, developing,
manufacturing or marketing new services and products or enhancing its existing
services and products on a timely basis or that Lifeline will be able to offer
such services and products at competitive prices. Also, there can be no
assurance that services, products or technologies developed by others will not
render Lifeline's services or products noncompetitive or obsolete.

                                      -14-
<PAGE>
 
The Company may experience risks and uncertainties associated with the
development of new information technology. These include the risks that such
development effort may not be completed on schedule, or at all, or within
budget, or that future developments in information technology will not render
the Company's system non-competitive; the risks that the Company does not
realize the intended benefits from the new system, once completed; and the
uncertainty associated with the substantial commitment of funds to the
development effort, including the risks that the Company will have available
significantly less cash to finance its operations, other capital expenditures
and future growth, including acquisitions.

The Company's growth is dependent on its ability to increase the number of
subscribers served by its monitoring centers. The Company's ability to continue
to increase service revenue is a key factor in its long-term growth, and there
can be no assurance that the Company will be able to do so. The Company's
failure to increase service revenue could have a material adverse effect on the
Company's results of operations.

The Company may expand its operations through the acquisition of additional
businesses. There can be no assurance that the Company will be able to identify,
acquire or profitably manage additional businesses or successfully integrate any
acquired businesses into the Company without substantial expenses, delays or
other operational or financial problems. In addition, acquisitions may involve a
number of special risks, including diversion of management's attention, failure
to retain key acquired personnel, unanticipated events, contingent liabilities
and amortization of acquired intangible assets. There can be no assurance that
the acquired businesses, if any, will achieve anticipated revenues or earnings.

The Company sells a significant portion of its products to healthcare providers
which establish their own Lifeline programs. These healthcare providers
typically rent, rather than sell, the Lifeline products to subscribers and
accordingly following such time as a product is no longer used by a subscriber,
it is returned to the healthcare provider and becomes available for rent to
another subscriber. As a result of this use and reuse of the Company's products,
sales of such products are dependent on growth in the number of subscribers and
on the ability of the Company to encourage its healthcare provider customers to
replace their existing inventory by continuing to enhance its products with new
features.

The Company's monitoring operations are concentrated principally in its
corporate headquarters facility. Although the Company believes that it has
constructed safeguards to protect against system failures, the disruption of
service at its monitoring facility, whether due to telephone or electrical
failures, earthquakes, fire, the 1998 move to new corporate headquarters, or
other similar events or for any other reason, could have a material adverse
effect on the Company's results of operations.

The Company's equipment sales have continued to decline as a result of the
Company's strategy of combining service and hardware offerings to support the
transition to a service oriented business. There can be no assurance that
service revenue will increase at a rate sufficient to offset the expected
decrease in equipment sales.

                                      -15-
<PAGE>
 
IMPACT OF THE YEAR 2000 ISSUE

The Year 2000 Issue is the result of computer programs being written using two
digits rather than four to define the applicable year. This could result in
computer programs that have date-sensitive software recognizing a date using
"00" as the year 1900 rather than the year 2000. Such errors could cause a
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.

The Company has implemented a formal Year 2000 program to determine the extent
of its own Year 2000 problems. As part of this program, the Company is in the
process of determining whether its operating systems need modifications to be in
compliance with the Year 2000. The Company has not yet fully assessed the Year
2000 compliance expense and related potential effect on the Company's earnings.
The Company anticipates that any modifications required to be made to its
software systems to comply with the Year 2000 Issue will be completed in a
timely manner. The Company has designed its new call center platform to be in
compliance with the Year 2000.

The Company has also initiated formal communications with significant suppliers
and other key third parties to determine the extent to which the Company is
vulnerable to those third parties' failure to resolve their own Year 2000 issue.
There can be no assurance that the systems of other companies on which the
Company's systems rely will be timely converted, or that a failure to convert by
another company, or a conversion that is incompatible with the Company's
systems, would not have a material adverse effect on the Company's results of
operations.

Report of Independent Accountants

To the Stockholders and Board of Directors of Lifeline Systems, Inc.:

We have audited the accompanying consolidated financial statements and financial
statement schedule of Lifeline Systems, Inc. ("The Company") listed in Items
14(a)(1) and 14(a)(2) of this Form 10-K. These financial statements and
financial statement schedule are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
the financial statement schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Lifeline Systems,
Inc. as of December 31, 1997 and 1996, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.
In addition, in our opinion, the financial statement schedule referred to above,
when considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material aspects, the information to be included
therein.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     A.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation 
     The consolidated financial statements include the accounts of Lifeline
     Systems, Inc. and its wholly owned subsidiaries (the "Company"). All
     significant intercompany balances and transactions have been eliminated.

     Use of Estimates in the Preparation of Financial Statements 
     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting periods. Actual results could differ from those
     estimates.

     Cash, Cash Equivalents, and Investments 
     The Company considers all securities purchased with a maturity of three
     months or less at the date of acquisition to be cash equivalents. The
     Company's investments are deemed to be available for sale. Short-term
     investments consist primarily of obligations of the US Government and its
     agencies, tax-exempt securities, commercial paper, and bank time deposits
     with maturities at date of acquisition beyond three months and less than
     one year. Long-term investments consist primarily of obligations of the US

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

A.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Inventories
Inventories are stated at the lower of cost or market, as determined by the
first-in, first-out method.

Property and Equipment
Property and equipment are carried at cost. Depreciation and amortization are
computed principally by the straight-line method over the useful lives of the
assets, typically three to five years, or, in the case of leasehold
improvements, over the lesser of the useful life or the lease term.

When assets are sold or retired, the related cost and accumulated depreciation
are removed from the accounts and any resulting gain or loss is credited or
charged to income. Expenditures for maintenance and repairs are charged to
expense as incurred; betterments are capitalized.

Goodwill
Goodwill is recorded at cost and amortized on a straight-line basis over an
estimated useful life not to exceed seven years. Amortization expense was
$542,000, $472,000, and $361,000 in 1997, 1996 and 1995, respectively.
Accumulated amortization amounted to $0 and $1,244,000 as of December 31, 1997
and 1996, respectively.

Impairment of long-lived assets
In accordance with Statement of Financial Accounting Standards ("SFAS") No. 121,
"Accounting for the Impairment of Long-lived Assets and for Long-Lived Assets to
be Disposed Of," the Company evaluates the possible impairment of long-lived
assets, including goodwill, whenever events or circumstances indicate that the
carrying value of the assets may not be recoverable. In December, 1997, the
Company initiated a reorganization plan to account for its approximately $11
million investment in technology for a new call center platform, the relocation
of the Company's corporate headquarters from its current Cambridge, MA facility
to a new facility in Framingham, MA, and other initiatives to lower operating
costs. In accordance with this plan, the Company analyzed the acquisitions of
the Communicall(R) brand of value-added supportive home monitoring services to
the elderly, Tele-Response and Support Services, Inc. who was a distributor of
the Company's personal response products and services, and the ProtectAlert(TM)
trade name. Based on an estimate of future discounted net cash flows, the
Company recorded a charge of $1.8 million to write down the carrying amounts of
these businesses to their estimated fair values. The charge is included in the
Company's results of operations for the year ended December 31, 1997 as part of
the restructuring charge.

As a result of the Company's reorganization plan, the Company also recorded a
non-cash accounting charge of $897,000 related to a write down of property,
plant and equipment associated with the Company's current call center, leasehold
improvements on its current facility, and certain assets related to the
aforementioned acquisitions. The charge is included in the Company's results of
operations for the year ended December 31, 1997 as part of the restructuring
charge.

A.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Product Warranty
The Company's products are generally under warranty against defects in material
and workmanship. The Company provides an accrual for estimated warranty costs at
the time of sale of the related products.

Revenue Recognition
Service revenues are associated primarily with providing monitoring and
maintenance of personal response products and are recognized ratably over the
contractual period. Revenues from the sale of personal response products are
recognized upon shipment. Finance income attributable to sales-type lease
contracts is initially recorded as unearned income and subsequently recognized
under the interest method over the term of the leases.

Income Taxes
The Company accounts for income taxes under a liability approach. Under this
approach, deferred tax assets and liabilities are recognized based on temporary
differences between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
temporary differences are expected to reverse.

Net Income Per Common Share
Net income per basic common share is computed by dividing income available to
common stockholders by the weighted-average number of common shares outstanding
for the period. Net income per diluted common shares is computed based on the
weighted average number of common and dilutive common equivalent shares
outstanding during each period. Common equivalent shares consist of stock
options and warrants calculated in accordance with SFAS No. 128, "Earnings per
Share."

Industry Segments
The Company operates in one industry segment. Its operations consist of
providing personal response services associated with the monitoring of those
products it designs, manufactures, and markets. Foreign revenues, from Canada,
comprise less than 10% of the Company's total revenues, and the Company has no
significant tangible assets in foreign countries.

Concentration of Credit Risk
Financial instruments which potentially subject the Company to concentration of
credit risk include cash, cash equivalents, investments, and trade receivables.
The Company sells its products primarily to hospitals and other healthcare
institutions. The Company performs ongoing credit evaluations of its customers
and, in the case of sales-type leases, the leased equipment serves as collateral
in the transactions. The Company has established guidelines relative to credit
ratings, diversification and maturities that maintain safety and liquidity. The
Company has not experienced any significant losses on these financial
instruments.

Reclassification
Certain prior year balances have been reclassified to conform to the current
year presentation.

D.   LEASING ARRANGEMENTS (continued)

As sales-type leases, the lease payments to be received over the term of the
leases are recorded as a receivable at the inception of the new lease. Finance
income attributable to the lease contracts is initially recorded as unearned
income and subsequently recognized as income under the interest method over the
term of the leases. The lease contracts are generally for five-year terms, and
the residual value of the leased equipment is considered to be nominal at the
end of the lease period.

The components of the net investment in sales-type leases are

As Lessee
The Company conducts its primary operations in a leased facility under a ten-
year operating lease which commenced in the second quarter of 1994. The lease
includes scheduled base rent increases over the term of the lease. The total
amount of base rent payments is being charged to expense on the straight-line
method over the term of the lease. The Company recorded a deferred credit to
reflect the excess of rent expense over cash payments upon the commencement of
the lease. In addition, the Company pays a monthly allocation of the building's
operating expenses and real estate taxes. The lease contains two five-year
renewal options.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

D. LEASING ARRANGEMENTS (continued)

In conjunction with the leased facility, the Company also entered into operating
lease arrangements for certain furniture, computer equipment, and leasehold
improvements totaling approximately $1.5 million.  These leases contain renewal
options and expire through 2001.

In November, 1997, the Company entered into a ten-year lease for an 84,000
square foot facility in Framingham, MA for its corporate headquarters. The
Company intends to occupy this new facility in late 1998.  Annual rental
payments under the lease approximate $775,000.  The lease contains two five-year
options to renew at the end of the initial lease term. The Company is currently
evaluating possible alternatives for its existing lease.

As a result of the Company's reorganization plan, the Company recorded a charge
of $731,000 for the rental commitment on its current facility.

The Company also has several operating lease arrangements for sales offices and
office equipment that expire through 2000 and leases certain equipment under
capital leases which expire through 2000.  Capital lease obligations are
collateralized by the related equipment.


Future minimum lease payments under capital and operating leases with initial or
remaining terms of one year or more are:

Net Income Per Common Share

The Company has adopted SFAS No. 128, "Earnings per Share" for the fiscal year
ended December 31, 1997.  This Statement replaces the presentation of primary
and fully diluted earnings per share ("EPS") with a presentation of  basic and
diluted EPS.  Basic EPS excludes dilution and is computed by dividing income
available to common stockholders by the weighted-average number of common shares
outstanding for the period.  Diluted EPS reflects the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of common
stock that then shared in the earnings of the entity.  A reconciliation of the
basic EPS to diluted EPS and dual presentation on the face of the statement of
income are also required.

Calculation of per share earnings is as follows:

Stock-Based Compensation Plans

The Company has adopted the disclosure requirements of SFAS No. 123 "Accounting
for Stock-Based Compensation."  The Company continues to recognize compensation
costs using the intrinsic value based method described in Accounting Principles
Board Opinion No. 25 "Accounting for Stock Issued to Employees."

In May, 1994 the stockholders approved the 1994 Stock Option Plan (the "1994
Plan").  The 1994 Plan provides that officers and key employees may be granted
either nonqualified or incentive stock options for the purchase of the Company's
common stock at the fair market value

on the date of grant. The employee options granted generally become exercisable
at a rate of 20% per year and expire ten years from the date of grant. Certain
options, as originally granted, became exercisable only to the extent the
Company achieved specific financial goals. During 1995 these options were
amended to provide for vesting on the earlier of the six year anniversary of the
date of grant or the original vesting schedule upon the achievement of the
aforementioned financial goals. As a result of this change, the Company incurred
additional compensation expense totaling $1.6 million, which is being amortized
based on a vesting schedule which approximates the expected date of meeting the
specific financial goals. Compensation expense of $79,000, $446,000, and
$384,000 was recorded in 1997, 1996, and 1995 and accumulated deferred
compensation was $975,000 and $896,000 at December 31, 1997 and 1996,
respectively.

The 1991 Stock Option Plan also remains in effect, providing for similar grants
to officers and employees.  Additionally, the 1991 Plan provides for an
automatic annual grant to non-employee directors.  The non-employee director
options become exercisable in three equal installments with the first
installment exercisable on the date of grant and the second and third
installments becoming exercisable on the second and third anniversaries of such
date.

Prior to the adoption of the 1994 Plan, several other stock option plans were in
effect and options which remain outstanding under those plans are included
below.

In May, 1996 the Company, upon approval by the Board of Directors and
stockholders, increased the total number of shares approved for future grant
under plans currently in effect by 300,000 for the 1994 Stock Option Plan and
25,000 for the 1991 Stock Option Plan.  At December 31, 1997 shares available
for future grants under all option plans were 309,150.

In May, 1995 the stockholders approved the Lifeline Employee Stock Purchase Plan
(ESPP) whereby eligible employees may invest up to 10% of their base salary in
shares of the Company's common stock.  The purchase price of the shares is 90%
of the fair market value of the stock on either the commencement date or the
date of purchase, whichever is lower.  Under the Plan, 200,000 shares of common
stock are available for purchase over ten offering periods through April, 2000,
of which approximately 162,116 shares remain available.  Shares purchased under
the ESPP totaled 15,012, 15,085, and 7,787 in 1997, 1996 and 1995, respectively.
The weighted-average grant-date fair value of shares purchased under the ESPP
was $17.79, $15.62 and $9.39 in 1997, 1996, and 1995, respectively.

For the purpose of providing pro forma disclosures, the fair values of shares
purchased were estimated using the Black-Scholes option-pricing model with the
following weighted-average assumptions used for purchases in 1997, 1996 and 1995
respectively:  a risk free interest rate of 5.94%, 5.41% and 5.37%; an expected
life of 6 months in each year; expected volatility of 30% in 1997 and 40% in
1996 and 1995; and no expected dividends.

in the amount of $100,000. The note, which bears interest at a rate of 6.3% per
annum, payable annually in arrears, is due September, 2002. In September, 1992
the Company issued 83,333 shares of its common stock to the Chief Executive

arrears, was due September 1, 1999. On February 24, 1997, the Company's Chief 
Executive Officer repaid the note in full, in part by exercising stock options 
and selling 10,700 shares of Common Stock back to the Company at their fair 
market value of $17.00 on such date, the proceeds of which were used to repay 
the note.

In connection with the 1993 acquisition of the assets of CarePartners, Inc., the
Company issued a warrant to purchase 100,000 shares of the Company's common 
stock at $4.78 per share, expiring in March, 1996. In September, 1995 the 
Company paid $539,000 to repurchase the warrant.

In January, 1997, the Board of Directors authorized the repurchase of an 
additional 100,000 shares of common stock for general corporate purposes. The 
Company has purchased 60,700 shares directly from the Company's Chief Executive 
Officer through December 31, 1997 for $1.1 million as part of this program, 
including the 10,700 shares repurchased on February 24, 1997. These shares were 
purchased from the Chief Executive Officer partly in connection with the 
repayment of the $250,000 note and associated tax expenses.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

G.  EMPLOYEE BENEFIT PLAN

The Company has a 401(k) defined contribution savings plan covering
substantially all of its employees. The Company's contributions, which are
included in selling, general and administrative expenses, were $354,000,
$184,000, and $152,000 for the years ended December 31, 1997, 1996 and 1995,
respectively.

H.  SUPPLEMENTAL CASH FLOW INFORMATION

The Company did not incur capital lease obligations in 1997 or 1996.  However,
the Company did incur a capital lease obligation to obtain certain equipment in
the amount of $41,000 in 1995.

Cash paid for income taxes amounted to $2,313,000, $2,679,000, and $2,908,000
during 1997, 1996, and 1995, respectively.  Interest paid was $20,000, $7,000,
and $8,000 during 1997, 1996, and 1995, respectively.

I.  REVOLVING CREDIT AGREEMENT

The Company secured a $4.0 million line of credit effective in January, 1996.
During 1997, the term of the credit facility was extended until March, 1998.
This credit agreement contains a number of covenants, including requirements
that the Company maintain certain levels of financial performance and capital
structure, limitations on the Company's capital and other expenditures, and
restrictions on the Company's capacity to secure additional debt financing. No
amounts were outstanding at December 31, 1997 and 1996. The Company is currently
in the process of renegotiating a new line of credit.

J. ACQUISITION

In July, 1996 the Company acquired all of the outstanding stock of CareTel, Inc.
of Toronto, Ontario, Canada through its subsidiary, Lifeline Systems (Canada),
Inc.  CareTel provided monitoring services similar to those offered by the
Company, directly to consumers under the brand name ProtectAlert.  The purchase
price was approximately $1.1 million in cash, all of which was paid in 1996.
The acquisition was accounted for as a purchase transaction, and, as a result,
the Company recorded goodwill of approximately $1,000,000.  The results of the
acquired business have been included in the Company's consolidated financial
statements from the date of acquisition.  See Note K.

K. RESTRUCTURING

In December, 1997, the Company initiated a plan of reorganization and
restructuring designed to account for an approximate $11 million investment in
technology for a new call center platform, the relocation of the Company's
corporate headquarters from its current Cambridge, MA facility to a new facility
in Framingham, MA, and other initiatives to lower operating costs.

<PAGE>
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

K.  RESTRUCTURING (continued)

As a result, in the fourth quarter of 1997, the Company recorded a $4.3 million
pre-tax charge to operations.  The Company took a charge for a minor workforce
reduction in such areas as sales and marketing, research and development and
administration.  This resulted in a pre-tax charge of $842,000 for employee
severance and related benefits, and none of these amounts were paid as of
December 31, 1997.  Also in connection with the restructuring plan, the Company
will take steps to decommission the current call center system.  Therefore, the
restructuring charge also included $304,000 of costs associated with the write
down to fair value of certain call center fixed assets.  Also in association
with the Company's relocation from its current Cambridge, MA facility to a new
facility in Framingham, MA, the restructuring charge included $1.2 million of
costs for the write down to fair value of certain leasehold improvements and
lease commitments on its current facility. The remaining restructuring charge
primarily related to $150,000 of costs associated with the write down to fair
value of equipment made obsolete from prior years' acquisitions, and $1.8
million for the write down of impaired goodwill.

Accrued restructuring charges in 1997 of $2.3 million represent the expected
future cash payments remaining at December 31, 1997. A summary of the
restructuring activity is presented below:

L.  NEWLY ISSUED ACCOUNTING STANDARDS

In June, 1997 the Financial Accounting Standards Board issued Statement No. 130
("SFAS" 130), "Reporting Comprehensive Income."  SFAS 130 requires changes in
comprehensive income to be shown in a financial statement that is displayed with
the same prominence as other financial statements. While not mandating a
specific financial statement format, SFAS 130 requires that an amount
representing total comprehensive income be reported. SFAS 130 will become
effective for fiscal years beginning after December 15, 1997. Reclassification
of financial statements for earlier periods is required for comparative
purposes. The Company does not believe that the adoption of SFAS 130 will have a
material impact on results of operations.

L.  NEWLY ISSUED ACCOUNTING STANDARDS (continued)

In June, 1997, the Financial Accounting Standards Board issued Statement No. 131
("SFAS" 131), "Disclosures about Segments of an Enterprise and Related
Information."  SFAS 131, which supersedes Statement No. 14, "Financial Reporting
for Segments of a Business Enterprise," changes the way public companies report
information about segments. SFAS 131, which is based on the management approach
to segment reporting, includes requirements to report segment information
quarterly and entity-wide disclosures about products and services, major
customers, and the material countries in which the entity holds assets and
reports revenues. SFAS 131 is effective for fiscal years beginning after
December 15, 1997. Restatement for earlier years is required for comparative
purposes unless impracticable. In addition, SFAS 131 need not be applied to
interim periods in the initial year; however, in subsequent years, interim
period information must be presented on a comparative basis. The Company does
not believe that the adoption of SFAS 131 will have a material impact on
financial statement disclosures.

            Base Rent shall be at the annual rate of Eight Hundred Fifty-Six
            Thousand Two Hundred Dollars ($856,200.00) and shall be payable in
            equal monthly installments, in 

                                       5
<PAGE>
 
            advance, each in the amount of Seventy-One Thousand Three Hundred
            Fifty and 00/100 Dollars ($71,350.00). Said annual rate of Base Rent
            was calculated by multiplying Ten Dollars ($10.00) by the number of
            rentable square feet in the Leased Premises (which the parties
            irrevocable agree is 84,420 square feet of rentable floor space) and
            adding Twelve Thousand Dollars ($12,000.00).


    The Base Rent shall be paid in advance on the first day of each full
calendar month of the Lease Term, and pro rata, in advance, for any portion of a
calendar month included at the beginning or end of the Lease Term with 1/30 of a
monthly payment being due for each day of a partial month, payable on the first
day of such partial month.

3.2A TIF Agreement; Reduction in Base Rent.  Tenant shall have the right to
     -------------------------------------                                 
seek, at the Tenant's expense,  a "TIF" agreement with the Town of Framingham
(the "Town") to reduce the real estate taxes assessed against the Property.
Landlord shall cooperate with Tenant in Tenant's efforts to obtain such a TIF
Agreement  provided that Landlord shall not be subjected to any liability for
the payment of any costs or expenses in connection therewith, and Tenant shall
indemnify and save harmless Landlord from any such costs and expenses. If,
pursuant to a TIF agreement entered into by the Town and the Tenant, the Town
reduces the real estate taxes the Town bills against the Property so that such
taxes are less than the Base Amount which the Town would have otherwise billed
to the Landlord, then the Landlord shall give the Tenant a credit towards the
payment of Base Rent which is equal to the amount of such reduction.  Such
credit shall be given to the Tenant in equal installments contemporaneously with
the period of time during which the actual bills for the real estate taxes
assessed against the Property as so reduced are due and payable by the Landlord.
(For example, assume that for fiscal year 1999 (that is July 1, 1999 - June 30,
2000) a TIF agreement is entered into by the Town and the Tenant pursuant to
which the Town reduces the real estate taxes the Town bills against the Property
so that such taxes are $1,200 less than the Base Amount which would have been
otherwise billed to the Landlord.  Assume further that the payment for the first
bill for said fiscal year which reflects such a reduction is due on October 1,
1999.  In this example, the Tenant would begin receiving a credit towards the
payment of the Base Rent in the amount of $100 (being 1/12th of $1,200)
commencing with the Base Rent payment due on October, 1, 1999 and continuing
monthly thereafter through and including the Base Rent payment due on September
1, 2000.)  If the period of time for which the Tenant is entitled to receive
such credits towards the payment of Base Rent exceeds the Term, the Landlord
will accelerate the final credits so that the Tenant receives the benefit of all
such credits by the end of the Term.

3.3  Additional Rent. In addition to the Base Rent, Tenant shall also pay during
     ---------------
the Lease Term, as Additional Rent, the following, each such amount to be paid
on the later to occur of (i) the first day of the next calendar month after such
amount is requisitioned and (ii) ten (10) business days after such amount is
requisitioned, except as otherwise stated:

    (1) Tenant's Proportionate Share of all increases in the amount of real
    estate taxes 

                                       6
<PAGE>
 
            imposed, assessed or levied upon the Property by the Town of
            Framingham, Massachusetts (the "Town") over the "Base Amount." The
            "Base Amount" shall be the amount of the real estate taxes first
            imposed, assessed or levied upon the Property by the Town in the
            first fiscal year (July 1 -June 30) for which the assessment date
            (the prior January 1) first occurs after the Term Commencement Date
            without regard to any reduction in the real estate taxes levied on
            the Property by the Town pursuant to any TIF agreement between the
            Tenant and the Town. (Section 3.2A above addresses how such a
            reduction is passed on to the Tenant by way of a credit towards the
            payment of Base Rent.) All such payments to be made when due, but in
            any event prior to any date on which interest or penalties would
            begin to accrue if such real estate tax bill is not paid. Landlord
            shall forthwith send to Tenant any bills received by Landlord for
            such real estate taxes together with the calculation of any increase
            over the Base Amount; and



            (2) Tenant's Proportionate Share of all Impositions (other than the
            real estate taxes addressed in Subsection (1) above) imposed,
                                           --------------
            assessed, levied or confirmed upon the Property (including, without
            limitation, any and all penalties, interest, recapture amounts and
            all other amount imposed, assessed, levied or confirmed upon all or
            any portion of the Property in connection with any breach, default
            or violation of any TIF agreement by the Tenant). All such payments
            to be made when due, but in any event prior to any date on which
            interest or penalties would begin to accrue on account of such
            Impositions if not paid. Landlord shall forthwith send Tenant any
            bills received by Landlord for Impositions; and

            (3) Tenant's Proportionate Share of all Operating Expenses.

            Notwithstanding the foregoing, it is agreed that, in the event
Landlord is required to pay into escrow with Landlord's Mortgagee an amount to
allow Landlord's Mortgagee to pay real estate taxes on the Property, any other
Impositions, or any Operating Expenses (including, without limitation, insurance
premiums) directly to the assessing or billing authority, then Landlord or
Landlord's Mortgagee may direct Tenant to pay certain portions of the Additional
Rent directly to Landlord's Mortgagee on a monthly (or less frequent basis)
rather than as set forth above.

            Notwithstanding anything contained herein to the contrary, all
monetary obligations of Tenant under this Lease, except for the obligation to
pay Base Rent, shall be deemed obligations to pay Additional Rent, unless such
presumption is repugnant to the context.

3.4  Payment of Estimated Operating Expenses. If notified by Landlord, Tenant
     --------------------------------------- 
shall make estimated monthly payments to Landlord to cover Tenant's
Proportionate Share of Operating Expenses that are expected to be incurred
during the current calendar year and each subsequent calendar year thereafter
falling entirely or partly within the Lease Term. The amount of such monthly
payments shall be determined as follows: on the Term Commencement Date and at
the beginning of each calendar year thereafter, Landlord shall submit to Tenant
a statement setting

                                       7
<PAGE>
 
forth Landlord's reasonable estimates (based on costs of which Landlord is aware
and other reasonable assumptions of Landlord) of the amount of Operating
Expenses that are expected to be incurred during such calendar year, and the
computation of Tenant's Proportionate Share of such anticipated Operating
Expenses. Tenant shall pay to Landlord on the first day of each month following
receipt of such statement an appropriate amount to amortize on a monthly basis
Tenant's Proportionate Share of the anticipated Operating Expenses, with
appropriate adjustments if any period includes less than one (1) full month. If
at any time during the Lease Term Landlord in Landlord's reasonable discretion
determines it appropriate to revise the estimates of Operating Expenses which
have been submitted, then Landlord may submit such revised estimates to Tenant,
and then commencing with the next monthly payment to be made by Tenant,
appropriate adjustment shall be made to the amount being paid by Tenant on
account of Tenant's Proportionate Share of anticipated Operating Expenses.
Within ninety (90) days after the expiration of each calendar year during the
Lease Term, Landlord shall submit to Tenant a statement certifying (i) Tenant's
Proportionate Share of the actual Operating Expenses incurred during the
preceding calendar year, (ii) the aggregate amount of the estimated payments, if
any, made by Tenant on account thereof, and (iii) any credit to which Tenant is
entitled. Tenant shall deduct the overpayment from its next estimated payment or
payments for Operating Expenses for the then current year unless the overpayment
exceeds 10% of the actual payments, in which event the Landlord shall refund the
same to Tenant within thirty days of submitting the statement to Tenant. If
Tenant's actual liability for such Operating Expenses exceeds the estimated
payments, if any, made by Tenant on account thereof, then Tenant shall pay to
Landlord within thirty days the total amount of such deficiency as Additional
Rent due hereunder.

    Tenant's liability for Tenant's Proportionate Share of the Operating
Expenses for the last calendar year falling entirely or partly within the Lease
Term shall survive the expiration of the Lease Term.  Similarly, Landlord's
obligation to refund to Tenant the excess, if any, of the amount of Tenant's
actual liability therefor shall survive the expiration of the Lease Term.

    Tenant or an independent, certified public accountant designated by Tenant
shall have the right, during regular business hours and after giving ten (10)
days' advance written notice to Landlord, to inspect, copy, and audit Landlord's
books and records relating to the Operating Expenses billed during any calendar
year falling within the Lease Term for a period of one (1) year following the
receipt by Tenant of any annual statement submitted pursuant to this Section.
If as a result of such audit it becomes clear that an error was made in the
calculation of Tenant's Proportionate Share of Operating Expenses, then an
appropriate adjustment shall be made promptly.

3.5 Lease to be Deemed Net. Tenant shall pay to Landlord the Base Rent and
    ----------------------
Additional Rent, free of any off-sets or deductions of any kind except as
provided for herein.
      
3.6 Tenant's Right to Seek Abatement. Tenant shall have the right to seek a
    --------------------------------
reduction in the valuation of the Leased Premises assessed for tax purposes
and to contest in good faith by appropriate proceedings, at Tenant's
expense, the amount or validity in whole or in part of any
    

                                       8
<PAGE>
 
Imposition or of the method by which any Imposition is calculated, assessed or
imposed; and may defer payment thereof if allowed by law, provided that (i)
Tenant shall provide Landlord with security reasonably satisfactory to Landlord
to assure payment of contested items; and (ii) Tenant shall immediately pay such
contested item or items if the protection of all or any portion of the Property
or of the Landlord's interest therein from any lien or claim shall, in the
reasonable judgment of Landlord, require such payment. Landlord shall not be
required to join in any proceedings referred to in Section 3.6 hereof unless the
                                                   -----------
provisions of any law, rule or regulation at the time in effect shall require
that such proceedings be brought by or in the name of Landlord, in which event
Landlord shall join in such proceedings or permit the same to be brought in its
name. Landlord shall cooperate with Tenant in Tenant's efforts to obtain any
such contest or proceeding described above provided that Landlord shall not be
subjected to any liability for the payment of any costs or expenses in
connection with any such proceedings, and Tenant shall indemnify and save
harmless Landlord from any such costs and expenses.

3.7  Landlord's Right to Seek Abatement. If Tenant does not exercise (or does
     ----------------------------------
not intend to exercise) its right set forth in Section 3.6 above, then the
                                               -----------
Landlord shall have the right to seek such a reduction and make such a tax
contest. Tenant shall cooperate with Landlord in any such tax contest provided,
however, that Tenant shall not be subjected to any liability for the payment of
any costs or expenses in connection with any such proceedings, and Landlord
shall indemnify and save harmless Tenant from any such costs and expenses.

3.8  Abatements Generally.  To the extent to which any tax refund payable as
     ---------------------                                                  
a result of any proceeding which Landlord or Tenant may institute, or payable by
reason of compromise or settlement of any such proceeding, may be based upon a
payment made by Tenant, then:  (i) Tenant shall be authorized to collect the
same (or the appropriate portion thereof) from the taxing authority making the
refund, subject, however, to Tenant's obligation to reimburse Landlord forthwith
for any expense incurred by Landlord in connection therewith; and (ii) if,
despite the authorization given to the Tenant in (i), the taxing authority
granting the tax refund pays the tax refund to the Landlord, then the Landlord
shall be deemed to have received the Tenant's portion of  such tax refund in
trust for the Tenant and the Landlord shall forthwith, after receiving such tax
refund, pay to the Tenant the amount of such tax refund to which the Tenant is
entitled after deducting therefrom any expense incurred by Landlord in
connection therewith so that the Tenant receives the same amount that the Tenant
would have received under (i) of this Section if the tax refund had been paid
directly to the Tenant and the Tenant had reimbursed the Landlord for expenses
incurred by Landlord.

3.9  Tax Credits and Deductions for Tenant Work.  The Tenant is entitled to
     ------------------------------------------                            
all investment tax credits and abandoned building deductions for the Tenant Work
offered by the Town and the Commonwealth of Massachusetts to the extent
permitted by applicable law and the Landlord will not claim the same unless
applicable law does not allow the Tenant to claim such tax credits.

3.10 Prepaid Rent. Tenant has paid to Landlord One Hundred Thousand Dollars
     ------------
($100,000.00), representing a prepayment of Base Rent to be applied as a credit
towards the first payment(s) of   

                                       9

Base Rent due hereunder.

     Landlord represents and warrants, to the best of Landlord's actual
knowledge, that the Property is served by water, sewer, electricity and
telephone which is supplied to the Property by lines coming directly from public
ways or from easements serving the Property (in which case, no additional
easements are needed).  As part of the Base Building Improvements provided for
pursuant to Article 16 below, the Landlord shall cause all the connections
            ----------                                                    
coming into the Building for such utilities to be in good working order. Tenant
shall make arrangements with appropriate utility or service companies for the
supply of utilities including (to the extent available) water, sewer, electric,
gas, telephone and other utilities or services used or consumed on the Property
and shall promptly pay all costs with respect to same, such payments to be made,
to the extent possible, directly to the proper authorities charged with
collecting the same, the foregoing to include all charges for such utilities or
services.  Except as otherwise specifically provided herein, Landlord shall be
under no obligation to furnish any utilities or services to the Property
(including the Leased Premises) and shall not be liable for any interruption or
failure in the supply of any such utilities or services not presently available
to the Leased Premises unless due to the Landlord's gross negligence or willful
misconduct.

                   ARTICLE 5 - INSURANCE
                               ---------

5.1  Required Coverage. Tenant covenants and agrees with Landlord that during
     -----------------
the Lease Term the following insurance shall be obtained by Tenant and carried
at Tenant's sole expense:

     (a) Tenant's comprehensive public liability insurance insuring and
indemnifying Tenant, Landlord, and Landlord's Mortgagee against liability for
injury to persons and damage to property which may be claimed to have occurred
upon the Property (including, without limitation, the Leased Premises) or the
sidewalks, ways and other real property adjoining the Property and covering all
Tenant's obligations under this Lease and with limits at least as high as the
amounts respectively stated below, or such higher limits in any case as may
reasonably be required in case of increase in risk or as may be customarily
carried in Massachusetts by prudent occupants of similar property, as determined
by Landlord in its reasonable discretion:  $3,000,000 for property damage,
$3,000,000 for injury or death of one person, and $5,000,000 for injury or death
of more than one person in any single accident.

     (b) Workmen's Compensation covering all Tenant's employees, contractors and
agents working on the Premises.

     (c) Any rent loss insurance (for a period not to exceed twenty-four
months), and any insurance required by Landlord's Mortgagee (provided the same
is customarily required by mortgage lenders making loans on comparable
properties) but the foregoing shall not include

                                      10
<PAGE>
 
environmental insurance.

5.2 Writing and Disposition of Insurance Policies. All insurance required under
    ---------------------------------------------
Section 5.1 above shall be written with companies reasonably satisfactory to
- -----------
Landlord and in forms customarily in use from time to time in the Greater Boston
area. Tenant shall furnish the Landlord with duplicates of said policies or
certificates of insurance (provided that such certificates are on a form which
is binding on the insurance company issuing the insurance and which is otherwise
acceptable to Landlord's Mortgagee), and said policies shall (i) name Landlord
and Landlord's Mortgagee as additional insured, as their respective interests
may appear, and (ii) provide that the coverage thereunder may not lapse or be
canceled without twenty (20) days prior written notice to Landlord, Landlord's
Mortgagee and Tenant.

5.3 Mutual Waiver of Subrogation. Landlord and Tenant each hereby releases the
    ----------------------------
other, its officers, directors, employees and agents, from any and all liability
or responsibility (to the other or anyone claiming through or under them by way
of subrogation or otherwise) for any loss or damage to property covered by valid
and collectible insurance, even if such loss or damage shall have been caused by
the fault or negligence of the other party, or anyone for whom such party may be
responsible. However, this release shall be applicable and in force and effect
only with respect to loss or damage (a) actually recovered from an insurance
company and (b) occurring during such time as the releasor's insurance policies
shall contain a clause or endorsement to the effect that any such release shall
not adversely affect or impair said policies or prejudice the right of the
releasor to recover thereunder. Landlord and Tenant each agrees that any fire
and extended coverage insurance policies will include such a clause or
endorsement as long as the same shall be obtainable without extra costs, or, if
extra cost shall be charged therefor, so long as the other party pays such extra
cost. If extra cost shall be chargeable therefor, each party shall advise the
other party and of the amount of the extra cost, and the other party, at its
election, may pay the same, but shall not be obligated to do so.
    
5.4 Blanket Policies. Nothing contained herein shall prevent Tenant from taking
    ----------------
out insurance of the kind and in the amounts provided for herein under a blanket
insurance policy or policies covering properties other than the Property,
provided however, that any such policy or policies of blanket insurance (a)
shall specify therein, or Tenant shall furnish Landlord with the written
statement from the insurers under such policy or policies, specifying the amount
of the total insurance allocated to the Property, which amounts shall not be
less than the amounts required herein, and (b) amounts so specified shall be
sufficient to prevent any of the insured from being a co-insurer within the
terms of the applicable policy or policies, and provided further, however, that
any such policy or policies of blanket insurance shall, as to the Property,
otherwise comply as to endorsements and coverage with the provisions herein.
    
5.5 Landlord's Insurance Covenants. Landlord covenants and agrees that during
    ------------------------------
the Lease Term it shall obtain at Tenant's expense (as Tenant's Proportionate
Share of Operating Expenses) the following insurance:

                                      11
<PAGE>
 
    (i)  all risk insurance against damage by fire or other casualty in an
amount at least equal to the replacement costs of the Leased Premises, all
Tenant Work and all fixtures (other than trade fixtures) in the Leased Premises
as reasonably determined from time to time by Landlord or (at Landlord's
election or upon Tenant's request) by appraisal made at the expense of Tenant by
an accredited insurance appraiser approved by Landlord. As for any fixture
installed by Tenant (other than trade fixtures), such fixture shall be added to
said all risk insurance provided that Tenant installed the fixture in compliance
with the terms of this Lease and Tenant provided to the Landlord, upon the
completion of the installation, a written notice which stated that such fixture
must be added to said insurance and which contained such information on the
fixture (including, without limitation, the fixture's replacement value) as
Landlord's insurance carrier may require. The deductible for said insurance may
not exceed $1,000 without the Tenant's prior written consent; and

    (ii) Landlord's comprehensive public liability insurance for injury to
persons and damage to property which may be claimed to have occurred upon the
Property or the sidewalks, ways and other real property adjoining said Property
and covering all Landlord's obligations under this Lease and with limits at
least as high as the amounts respectively stated below:  $3,000,000 for property
damage, $3,000,000 for injury or death of one person, and $5,000,000 for injury
or death of more than one person in any single accident.


                   ARTICLE 6 - TENANT'S ADDITIONAL COVENANTS
                               -----------------------------

    Tenant covenants and agrees during the Lease Term and such further time as
Tenant occupies the Leased Premises or any part thereof:

6.1 Performing Obligations. To perform fully, faithfully and punctually all of

all charges, rates and other sums which by the terms of this Lease are to be
paid by Tenant.
 
6.2 Use. To use the Leased Premises only for the Permitted Uses, and for no
    ---
other purposes.
    
6.3 Maintenance and Repair. At Tenant's expense, and except for reasonable wear
    ----------------------
and tear and damage from fire or other casualty, to keep the Property
(including, without limitation, all interior and exterior glass, all systems
serving the Leased Premises, and all parking areas, driveways, walkways and
landscaped areas serving or appurtenant to the Property) clean, neat, properly
maintained and in good order, repair and condition, and to arrange for, or enter
into contracts regarding the provision of such services as are necessary to do
so (including, without limitation, janitorial services and the removal of
rubbish and other wastes from the Property electric lighting to the exterior of
the Building, parking areas, driveways, and walkways serving the Property,
landscaping of the Site, and the removal of snow and ice from all parking areas,
driveways, and walkways serving the Property) and to keep the Property in as
good condition, order and repair as the same are at the Term Commencement Date
or thereafter may be put, reasonable wear and use
    

                                      12
<PAGE>
 
and damage by fire or other casualty only excepted, it being understood that the
foregoing exception for reasonable wear and use shall not relieve Tenant from
the obligation to keep the Property in good order, repair and condition
including, without limitation, all necessary and ordinary non-structural
repairs, replacements and the like, except as otherwise explicitly set forth in
the Lease. Tenant also agrees to abide by reasonable rules and regulations which
may be adopted by Landlord from time to time. Notwithstanding the foregoing, the
Landlord shall be responsible for (a) the maintenance, repair and replacement
obligations set forth in Article 6A below; and (b) if any repair or replacement
to be performed by Tenant hereunder is required because of a defect in the Work
arising within one (1) year of the Substantial Completion of the Work and the
Tenant gives the Landlord written notice of such defect within said one year
then Landlord shall be obligated to perform such repair or replacement at the
Landlord's sole cost and expense (and not as part of the Operating Expenses).

6.4 Compliance with Laws. Except for the Landlord's compliance responsibilities
    --------------------
set forth elsewhere in this Lease and Tenant's compliance responsibilities
regarding Hazardous Materials which are governed exclusively by Article 18
                                                                ----------

promptly with all present and future laws, ordinances, orders, rules,
regulations and requirements of all federal, state and municipal governments,
departments, commissions, boards and officials, foreseen and unforeseen,
ordinary as well as extraordinary, which may be applicable to the Property or to
Tenant's use, occupancy or presence in or at the Property, except that the
Tenant may defer compliance so long as the validity of any such law, ordinance,
order, rule, regulation or requirement shall be contested by Tenant in good
faith and by appropriate legal proceedings, and:

    (a) If by the terms of such law, ordinance, order, rule, regulation or
requirement, compliance therewith pending the prosecution of any such proceeding
may legally be delayed without the incurrence of any lien, charge or liability
or any kind against all or any portion of the Property and without subjecting
Tenant or Landlord to any liability, civil or criminal, for failure so to comply
therewith, Tenant may delay compliance therewith until the final determination
of such proceeding, or

    (b) If any lien, charge or civil liability would be incurred by reason of
any such delay, Tenant nevertheless may contest as aforesaid and delay as
aforesaid, provided that such delay would not subject Landlord to criminal
liability or fine, and Tenant (i) furnishes to Landlord security, reasonably
satisfactory to Landlord, against any loss or injury by reason of such contest
or delay, and (ii) prosecutes the contest with due diligence.

6.5 Payment for Tenant's Work. To pay promptly when due the entire cost of any
    -------------------------
work to the Property undertaken by Tenant so that the Property shall at all
times be free of liens for labor and materials; promptly to clear the record of
any notice of any such lien; to procure all necessary permits and before
undertaking such work; to do all of such work in a good and workmanlike manner,
employing materials of good quality and complying with all governmental
requirements; and to save Landlord harmless and indemnified from all injury,
loss, claims or damage to any

person or property occasioned by or growing out of such work.

6.6  Indemnity. To save Landlord harmless and indemnified from, and to defend
     ---------
Landlord against, all injury, loss, claims or damage (including reasonable
attorneys' fees) to any person or property while on the Leased Premises unless
arising from any omission, fault, negligence or other misconduct of Landlord, or
its agents, servants, employees, or contractors; to save Landlord harmless and
indemnified from, and to defend Landlord against, all injury, loss, claims or
damage (including reasonable attorneys' fees) to any person or property
occasioned by any act, omission, neglect or default of Tenant or Tenant's
agents, servants, employees, contractors, guests, invitees or licensees while on
the Site, or on the roads or property adjacent to the Site.
    
6.7  Personal Property at Tenant's Risk. That all personal property, equipment,
     ----------------------------------

risk of Tenant; and that Landlord shall not be liable for any damage which may
be caused to such property or the Leased Premises or any other part of the

has a right under this Lease to cure such default.
    
6.9  Yield Up. At the termination of this Lease, peaceably to yield up the
     --------
Leased Premises and the Property clean and in good order, repair and condition,

shall restore any damage caused by such removal and provided further that if
                                                    -------- -------
Tenant fails so to restore the Leased Premises, then Tenant shall pay all of
Landlord's costs to make such restoration.
    
6.10 Subordination. Upon the request of Landlord, to execute and deliver all
     -------------
such instruments as may reasonably be requested to subordinate this Lease to any
mortgages or deeds of trust securing notes or bonds executed by Landlord and to
all advances made thereunder and to the interest thereon and all renewals,
replacements and extensions thereof, provided that the mortgagee or trustee
                                     --------
shall agree to recognize this Lease in the event of foreclosure if Tenant is not
in material default beyond the expiration of any applicable grace period allowed

16 or any other provision in this Lease which obligates the Landlord to prepare
- --
the Leased Premises and the Property for Tenant's occupancy; (f) be bound by any
amendment or modification to the Lease entered into without the consent of such
mortgagee or trustee. Any such mortgagee or trustee may at any time subordinate
its mortgage or deed of trust to this Lease, without Tenant's consent, by notice
in writing to Tenant and thereupon this Lease shall be deemed prior to such
mortgage or deed of trust without regard to their respective dates of execution,
delivery and recording; and in that event such mortgagee or trustee shall have
the same rights with respect to the Lease as though it had been executed and
delivered (and notice thereof recorded) prior to the execution and delivery and
recording of the mortgage or deed of trust.

6.11 Estoppel Certificates. From time to time, for delivery to a prospective
     ---------------------
purchaser or mortgagee of the Leased Premises or Building or to any assignee of
any mortgage of the Property, upon not less than ten (10) days prior written
request by Landlord, to execute, acknowledge and deliver to the Landlord a
statement in writing certifying: (a) that this Lease is unamended (or, if there
have been any amendments, stating the amendments); (b) that it is then in full
force and effect, if that be the fact; (c) the dates to which Rent and any other
payments to Landlord have been paid; (d) any defenses, offsets and counterclaims
which Tenant has knowledge of at the time of the execution of said statement
with respect to Tenant's obligation to pay Rent and to perform any other
obligations under this Lease or that there are none, if that be the fact; and
(e) such other data as may reasonably be requested. Any such statement may be
relied upon by such prospective purchaser or mortgagee of the Property, or
portion thereof, or any assignee of any mortgagee of the Property, or portion
thereof.
      
6.12 Nuisance. At all times during the Lease Term and such further time as the
     --------
Tenant occupies the Leased Premises, not to injure, overload, deface or
otherwise harm the Property; nor commit any nuisance; nor to do or suffer any
waste to the Property; nor permit the emission of any objectionable noise or
odor; nor make any use of the Property which is contrary to any law or ordinance
or which will invalidate any insurance policy or other applicable legal
requirement covering the Building or any portion thereof; nor handle, store, or
dispose of Hazardous Materials except as may be permitted by Article 18 below.

6.13 Changes and Alterations. Tenant shall have no authority, without the
     -----------------------
express written consent of Landlord (which consent shall not be unreasonably
withheld or delayed) to alter, remodel, reconstruct, demolish, add to, improve
or otherwise change the Leased Premises, except that Tenant shall have such
authority, without the consent of Landlord, to make repairs to the Premises and
do such things as are appropriate to comply with the obligations imposed on
Tenant under other provisions of this Lease.

     Tenant shall not construct or permit any other alterations, installations,
additions or improvements to the Leased Premises or the Property (including,
without limitation, any exterior signs, satellite dishes, antennas, generators
and exterior equipment) ("Alterations") without having first submitted to
Landlord plans and specifications therefor for Landlord's approval, which
approval shall not be unreasonably withheld or delayed provided that:

                                      15
<PAGE>
 
         (i)   if the improvement involves a sign or will otherwise be visible
from the exterior then the improvement must be compatible with the architectural
and aesthetic qualities of the Building and the Site and, as with any
Alteration, must be in compliance with all applicable legal requirements
(including, without limitation, the zoning ordinance and building code of the
Town) ; and

         (ii)  the improvement must be non-structural and have no adverse effect
on the plumbing, heating (and cooling), mechanical, electrical or other systems
or services in the Building, and the improvement (except for signs) must be
entirely within the Leased Premises; and

         (iii) the change, when completed will not materially adversely affect
the value of the Building; and

         (iv)  Tenant demonstrates to Landlord's satisfaction that the
improvement will be made in accordance with applicable legal requirements using
good quality materials and good quality construction practices and will not
result in any liens on the Property; and

         (v)   as soon as such work is completed, Tenant will have prepared and
provide Landlord with "as-built" plans (in form reasonably acceptable to
Landlord) showing all such work; and

         (vi)  Tenant will comply with any rules reasonably promulgated by
Landlord in connection with the going of any work, and if requested by Landlord,
Tenant will obtain and maintain Builder's Risk insurance in connection with such
work.

    Tenant shall have the right to make minor alterations from time to time in
the interior of the Leased Premises without obtaining Landlord's prior written
consent therefor, provided that all of such changes conform to all of the above
requirements in all respects, and further provided that Tenant provides Landlord
with a written description of such change (and such other data as Landlord may
request) not later than 30 days after each such alteration is made, and further
provided that the aggregate cost of such alterations may not exceed the
"Threshold Amount" in any twelve month period.  The "Threshold Amount" shall be
$25,000 for the first Lease Year and, thereafter, the Threshold Amount shall be
increased on each anniversary of the Term Commencement Date by the same
proportion (expressed as a percentage) of increase in the "Index" from the
amount of the "Index" existing as of the Term Commencement Date.  The "Index"
shall mean the Consumer Price Index for Greater Boston - All Consumers published
by the United States Department of Labor.

                              -------------------------------

    Landlord covenants and agrees during the Lease Term:

                                      16
<PAGE>
 
6A.1     Landlord's Maintenance, Repair and Replacement Obligations.
         -----------------------------------------------------------
         (a) To repair, maintain and replace the structural components of the
Building including the roof, but specifically excluding interior and exterior
                                              ---------                      
glass, so as to keep them in good condition and repair, reasonable wear and use
and damage by fire or other casualty only excepted.  As part of the Base
Building Improvements, the Landlord shall replace the roof at the Landlord's
expense.  Thereafter, the cost of maintaining and repairing the roof (but not
the replacement thereof which shall be Landlord's responsibility at its sole
expense) shall be part of the Operating Expenses to the extent that Landlord was
not reimbursed for such costs by any manufacturer or installer guaranties and
Tenant shall pay Tenant's Proportionate Share thereof. All costs incurred by
Landlord in performing its responsibilities under this subsection (a) for the
                                                       --------------        
other structural components of the Building shall be at Landlord's expense and
shall not be part of the Operating Expenses unless such repair, maintenance or
replacement is due to damage caused by Tenant or Tenant's agents, servants,
employees, contractors, guests, invitees or licensees, in which case such costs
shall be paid for by Tenant; and

         (b) To be responsible for the capital replacement of the air
conditioning and other systems serving the Building, in circumstances where any
such system cannot reasonably be repaired or according to prudent building
management practices should be replaced (except in any case where such
replacement is necessitated due to Tenant's failure to maintain the system
properly). The costs of such capital replacements shall be included in the
Operating Expenses to the extent that Landlord was not reimbursed for such costs
by any manufacturer or installer guaranties, and Tenant shall be responsible for
the payment of Tenant's Proportionate Share thereof, provided that such capital
replacement costs shall be amortized over the reasonable useful life of the
replacement item and Tenant shall be responsible only for those portion of such
costs allocable to periods during the Lease Term.

         (c) if any repair or replacement to be performed by Tenant under
Section 6 above is required because of a defect in the Work arising within one
- ---------
(1) year of the Substantial Completion of the Work and the Tenant gives the
Landlord written notice of such defect within said one year then Landlord shall
be obligated to perform such repair or replacement at the Landlord's sole cost
and expense (and not as part of the Operating Expenses).

         Landlord shall never be liable for damages caused by its failure to
make any such repairs, replacements or maintenance, provided that Landlord has
used reasonable efforts to attempt to have such repair, replacement or
maintenance done, after having been notified by Tenant that such repair,
replacement or maintenance must be done promptly and that Tenant will be damaged
by the failure to make or perform such repairs, replacements or maintenance
promptly.

6A.2     Landlord's Obligations Regarding Compliance With Laws.  At Landlord's
         -----------------------------------------------------                
expense and not as part of the Operating Expenses, to cause the Leased Premises
to be in compliance with all laws ordinances, orders, rules, regulations and
requirements of all federal, state and municipal governments departments,
commissions, boards and officials which are in effect as of the Term

                                      17
<PAGE>
 
Commencement Date and which are applicable to the Leased Premises as of the Term
Commencement Date (the "Pre-Existing Governmental Requirements") and to obtain
all permits and approvals required therefor under the Pre-Existing Governmental
Requirements  provided, however, that Landlord shall not be responsible for any
non-compliance caused in any way by the Tenant Work, any other work done to the
Leased Premises or changes made to the Leased Premises (other work or changes
done by Landlord, its agents, servants, employees, or contractors) or Tenant's
use, occupancy or presence in, on or at the Leased Premises (except for the As
of Right Uses defined in Section 16.2 below).  Notwithstanding the foregoing,
                         ------------                                        
Landlord's responsibilities regarding Hazardous Materials are governed
exclusively by Article 18 below.  In addition, the Landlord shall be responsible
               ----------                                                       
for performing the Landlord's maintenance, repair and replacement
responsibilities set forth in Section 6A1 above in compliance with all present
                              -----------                                     
and future laws, ordinances, orders, rules, regulations and requirements of all
federal, state and municipal governments, departments, commissions, boards and
officials, foreseen and unforeseen, ordinary as well as extraordinary, which may
be applicable to the Leased Premises and the cost of such compliance shall be at
Landlord's expense (and not part of the Operating Expenses) unless the law being
complied with went into effect or became applicable to the Leased Premises after
the Term Commencement Date, in which case such cost shall be part of the
Operating Expenses and Tenant shall be responsible for the payment of Tenant's
Proportionate Share thereof provided that any capital replacement costs shall be
amortized over the reasonable useful life of the replacement item and Tenant
shall be responsible only for those portion of such costs allocable to periods
during the Lease Term.

6A.3     Payment of Tenant's Cost of Enforcement.  To pay on demand Tenant's
         ---------------------------------------                            
reasonable out-of-pocket expenses, including reasonable attorneys' fees,
incurred in enforcing any obligation of Landlord under this Lease or in curing
any default by Landlord under this Lease, provided that Tenant is successful in
enforcing such obligation or has a right under this Lease to cure such default.


                          ARTICLE 7 - QUIET ENJOYMENT
                                      ---------------

         Landlord covenants that Tenant on paying the Rent and performing
Tenant's obligations under this Lease shall peacefully and quietly have, hold
and enjoy the Leased Premises throughout the Lease Term or until it is
terminated as in this Lease provided without hindrance by Landlord or by anyone
claiming by, through or under Landlord.

                     ARTICLE 8 - DAMAGE AND EMINENT DOMAIN
                                 -------------------------

8.1      Fire and Other Casualty. In the event that, at any time during the term
         -----------------------
hereof (including any extended term), the Leased Premises are totally damaged or
destroyed by fire or other casualty or damaged so as to render them or a
material portion thereof untenantable, then there shall be a

                                      18
<PAGE>
 
just and proportionate abatement of the Rent payable hereunder, until the Leased
Premises are made suitable for Tenant's occupancy. In the event of any
destruction or damage to the Leased Premises caused by fire or other casualty,
Landlord shall proceed at its expense (except that Tenant shall promptly fund
any insurance deductible) and with reasonable diligence to repair and restore
the Leased Premises to substantially the same condition they were in immediately
prior to such casualty. Notwithstanding the foregoing, if the Landlord, in its
reasonable discretion, determines that either (i) timely restoration is not
possible or practical and more than forty percent (40%) of the Leased Premises
has been damaged or destroyed; or (ii) that there are or will be insufficient
insurance proceeds available to accomplish timely restoration of the Leased
Premises (provided that Landlord has maintained the all risk insurance on the
Leased Premises as provided for in Section 5.5); or (iii) the
                                   ----------- 
Landlord's Mortgagee will not authorize the release of insurance proceeds to pay
for the restoration of the Leased Premises, then Landlord shall have the right
to terminate this Lease by written notice given to Tenant within sixty (60) days
after the Landlord receives notice from the Tenant of the occurrence of any
destruction or damage to the Leased Premises by fire or other casualty. In the
event that the Landlord has not terminated this Lease as provided for in the
preceding sentence, then the Landlord shall use reasonable diligence to repair
and restore the Leased Premises to substantially the same condition they were in
immediately prior to such destruction or damage to the Leased Premises. If the
Landlord has not commenced the repair or restoration of the Leased Premises
within ninety (90) days after the Landlord receives notice from the Tenant of
the occurrence of such destruction or damage or, after such commencement, the
Landlord is not proceeding with reasonable diligence to repair or restore the
Leased Premises (subject to the funding of the insurance proceeds, the payment
of the insurance deductible by the Tenant and force majeure) then the Tenant may
terminate this Lease by sending written notice to the Landlord. In the event the
Leased Premises have not been restored to a condition substantially suitable for
their intended purpose within one hundred eighty (180) days after the Landlord
receives notice from the Tenant of such destruction or damage to the Leased
Premises, then either Landlord or Tenant may terminate this Lease by written
notice given to the other within fifteen (15) days following such one hundred
eighty (180) day period, (provided, however, that in the case of a notice of
termination coming from Tenant, Tenant must give its notice of termination to
Landlord before the Leased Premises are so restored). If Landlord sends a notice
of termination as aforesaid, then Tenant may, within one week of receiving such
notice, give the Landlord a written notice extending the time period for such
restoration by an additional ninety days (90) (provided that Tenant must have
promptly funded to Landlord the insurance deductible); in which case the Lease
Term shall automatically be extended, without the necessity of further action by
any party, for a period equal to the time Rent abates beyond one hundred eighty
(180) days from the date the Landlord received notice from the Tenant of such
destruction or damage to the Leased Premises. In the event the Leased Premises
have not been restored to a condition substantially suitable for their intended
purpose within said ninety (90) additional days, then either Landlord or Tenant
may terminate this Lease by written notice given to the other within fifteen
(15) days following such ninety (90) day additional period (provided that, in
the case of a notice of termination coming from Tenant, such notice must also be
sent before the Leased Premises has been so restored) In the event that, during
the last two (2) years of the Lease Term the Leased Premises are totally damaged
or destroyed by fire or other casualty or damaged so as  

                                      19
<PAGE>
 
to render them or a material portion thereof untenantable, then either Landlord
or Tenant may terminate this Lease by written notice given to the other party
within sixty (60) days after the Landlord receives notice from the Tenant of
such total damage or destruction of the Leased Premises by the occurrence of
fire or other casualty.

8.2 Eminent Domain. Landlord reserves for itself all rights to any damages or
    --------------
awards with respect to the Leased Premises and the leasehold estate hereby
created by reason of any exercise of the right of eminent domain, or by reason
of anything lawfully done in pursuance of any public or other authority; and by
way of confirmation Tenant grants and assigns to Landlord all Tenant's rights to
such damages so reserved, except as otherwise provided herein. Tenant covenants
to execute and deliver any instruments confirming such assignment as Landlord
may from time to time reasonably request. If all the Leased Premises are taken
by eminent domain, this Lease shall terminate when Tenant is required to vacate
the Leased Premises or such earlier date as the Tenant is required to begin the
payments of rent to the taking authority. If a partial taking by eminent domain
results in so much of the Leased Premises or the Site being taken as to render
the Leased Premises or the Site or a material portion of the Leased Premises or
the Site unsuitable for Tenant's continued use and occupancy (including, without
limitation, if so many of the parking spaces on the Site are taken so as to
render Tenant's use of the Leased Premises not in compliance with the Town's
zoning by-laws or so as to result in there not being enough parking spaces for
Tenant's employees), as reasonably determined by Landlord in its reasonable
discretion, either Landlord or Tenant may elect to terminate this Lease as of
the date when the Tenant is required to vacate the portion of the Leased
Premises so taken or as of the date that Tenant is required not to use the
material portion of the Site so taken, by written notice to the other given not
more than ninety (90) days after the date on which Tenant or Landlord, as the
case may be, receives notice of the taking. If a partial taking by eminent
domain does not result in such portion of the Leased Premises or Site as
aforesaid being taken, then this Lease shall not be terminated or otherwise
affected by any exercise of the right of eminent domain. Whenever any portion of
the Leased Premises shall be taken by any exercise of the right of eminent
domain, and if this Lease shall not be terminated in accordance with the
provisions of this Section 8.2, Landlord shall, at its expense, proceeding with
                   -----------
all reasonable dispatch, provided sufficient condemnation proceeds are available
therefor (or, if not, provided Tenant, in its sole discretion, provides
additional funds needed above the amount of the condemnation proceeds available)
do such work as may be required to restore the Leased Premises or what remains
thereof (not including Tenant's trade fixtures, business equipment and
furniture) as nearly as may be to the condition they were in immediately prior
to such taking, and Tenant shall at its expense, proceeding with all reasonable
dispatch, do such work to its trade fixtures, business equipment and furniture,
as may be required. A just proportion of the Rent payable hereunder, according
to the nature and extent of the taking shall be abated from the time Tenant is
required to vacate that portion of the Leased Premises taken. If the Premises
have not been restored to a condition substantially suitable for their intended
purpose within one hundred twenty (120) days of said taking, Tenant may elect to
terminate this Lease by written notice to Landlord sent within fifteen (15) days
following such one hundred twenty (120) day period (provided that Tenant sends
such written notice prior to such restoration being completed).

                  ARTICLE 9 - DEFAULTS BY TENANT AND REMEDIES
                              -------------------------------

9.1   The Condition. If any default by Tenant continues, in case of payment of
      -------------    
Rent or other monetary payments due hereunder for more than five (5) days after
notice thereof to Tenant (provided, however, that Tenant shall be entitled to
only two (2) such notices during each calendar year and if any subsequent
default of payment of Rent or other monetary payment continues for more than
five (5) days, Landlord shall have all the rights set forth herein without the
need of any notice), or in the case of a non-monetary default for more than
thirty (30) days after written notice thereof to Tenant and such additional
time, if any, as is reasonably necessary to cure the default provided Tenant has
commenced cure within such thirty (30) day period and is diligently prosecuting
such cure to completion; or if Tenant becomes insolvent, makes any assignment
for the benefit of creditors, commits any act of bankruptcy or files a petition
under any bankruptcy or insolvency law; or if such a petition filed against
Tenant is not dismissed within ninety (90) days; or if a receiver or similar
officer becomes entitled to Tenant's interest in this Lease and it is not
returned to Tenant within ninety (90) days; or if Tenant's interest in this
Lease is taken on execution or other process of law in any action against
Tenant; then Landlord may immediately or at any time thereafter and without
demand or further notice make entry and repossess the Leased Premises as of
Landlord's former estate, without prejudice to any other remedies, and thereupon
this Lease shall terminate; and in case of such termination, or termination by
legal proceedings for default, Landlord may remove all of Tenant's property from
the Leased Premises and store the same in any public warehouse or other suitable
location all at the expense and risk of Tenant.

9.2   Reimbursement of Landlord's Expenses.  In the case of termination of this
      ------------------------------------                                     
Lease pursuant to Section 9.1, Tenant shall reimburse Landlord for all expenses
                  -----------                                                  
arising out of such termination, including without limitation, all costs
incurred in collecting amounts due from Tenant under this Lease (including
reasonable attorneys' fees, costs of litigation and the like); all expenses
incurred by Landlord in attempting to relet the Premises or parts thereof
(including advertisements, brokerage commissions, Tenant's allowances, lease
inducements, costs of preparing space, and the like); and all Landlord's other
reasonable expenditures necessitated by the termination.  The reimbursement from
Tenant shall be due and payable immediately from time to time upon notice from
Landlord that an expense has been incurred, without regard to whether the
expense was incurred before or after the termination.

9.3   Damages. Landlord may elect by written notice to Tenant within four months
      -------
following such termination to be indemnified for loss of Rent by a lump sum
payment representing the then present value of the amount of Rent which would
have been paid in accordance with this Lease for the remainder of the Lease Term
minus the then present value of the aggregate fair market rent payable for the
Leased Premises for the remainder of the Lease Term (if less than the Rent
payable hereunder), estimated as of the date of the termination, and taking into
account reasonable projections of vacancy and time required to re-lease the
Leased Premises (The "Lump Sum Election"). (For the purposes of calculating the
Rent which would have been paid hereunder for the lump sum payment calculation
described herein, the last full year's Additional Rent under this

                                      21
<PAGE>
 
Lease plus four percent (4%) compounded annually is to be deemed to be
Additional Rent for each year thereafter. The Federal Reserve discount rate (or
equivalent) plus 150 basis points shall be used in calculating present values.)
Should the parties be unable to agree on a fair market rent, the matter shall be
submitted, upon the demand of either party, to the Boston, Massachusetts office
of the American Arbitration Association, with a request for arbitration in
accordance with the rules of the Association by a single arbitrator who shall be
an MAI appraiser with at least ten years experience as an a appraiser of
suburban commercial real estate in the Eastern Massachusetts area. The parties
agree that a decision of the arbitrator shall be conclusive and binding upon
them. Should Landlord fail to make the election provided for in this Section
                                                                     ------- 
9.3, Tenant shall indemnify Landlord for the loss of Rent by a payment at the
- ---
end of each month which would have been included in the Lease Term, representing
the difference (to be ascertained monthly) between the Rent which would have
been paid in accordance with this Lease and the rent actually derived from the
Leased Premises by Landlord for such month (the amount of rent deemed derived
shall be the actual amount less any portion thereof attributable to Landlord's
reletting expenses described in Section 9.2 which have not been reimbursed by
                                -----------   
Tenant thereunder).


      In lieu of full recovery by Landlord of all sums payable under all the

Landlord to prove and obtain in a proceeding for bankruptcy, insolvency,
arrangement or reorganization, by reason of the termination, an amount equal to

not paid within five (5) days after notice thereof to Tenant or, if Landlord has
already given Tenant one (1) notice of Rent or other monetary payments being due
hereunder in that calendar year, then within five (5) days of being due,
Landlord may, at its option, without notice and in addition to all other
remedies hereunder, impose a late charge on Tenant equal to 1% of the amount in

                    ARTICLE 10 - ASSIGNMENT AND SUBLETTING
                                 -------------------------

10.1  Definitions.  As used in this Article 10, the terms "assignment" and
      -----------                   ----------                            
"sublease"  shall mean any assignment of all or any portion of or interest in
this Lease, any sublease or license of the Leased Premises or any portion
thereof, any occupancy of the Leased Premises by someone other than the Tenant,
or any transfer of Tenant's interest in this Lease by operation of law, merger
or consolidation of Tenant into any other firm or corporation, or the transfer
or sale of a controlling interest in Tenant, whether by sale of its capital
stock or otherwise.  As used in this Article 10, the terms "assignee" and
                                     ----------                          
"sublessee" shall mean any assignee of all or any portion of or interest in this
Lease, any sublessee or licensee of the Leased Premises or any portion thereof,
any occupant of the Leased Premises or any transferee of Tenant's interest in
this Lease by operation of law, merger or consolidation of Tenant into any firm
or corporation or the transferee or buyer of a controlling interest in Tenant,
whether by sale of capital stock or otherwise.

10.2  Limitation on Assignments and Subleases.  Tenant shall not make an
      ---------------------------------------                           
assignment or enter 

                                      23
<PAGE>
 
into a sublease without the Landlord's prior written consent which consent will
not be withheld or delayed unreasonably except under circumstances where Tenant
is in default of any covenant in this Lease beyond applicable grace and cure
periods (if any). In the event that Tenant is in default of any covenant of this
Lease beyond applicable grace and cure periods (if any), such consent may be
withheld in Landlord's absolute discretion until Tenant is no longer in default.
Thereafter, as long as Tenant is not in default of any covenant in this Lease
beyond applicable grace or cure periods, if any, Landlord's consent to such
assignment or sublease shall not be withheld or delayed unreasonably.

     It is agreed that in requesting Landlord's consent to any assignment or
sublease, Tenant shall provide such information regarding the proposed assignee
or sublessee and the proposed assignment or sublease as Landlord may reasonably
request.  Tenant shall pay to Landlord, as Additional Rent, Landlord's
reasonable legal fees and other expenses incurred in connection with any
proposed assignment or sublease, including fees for review of documents and
investigations of proposed assignees or sublessees.

     Notwithstanding the foregoing, but not in limitation of any other provision
hereof, the prior consent of Landlord shall not be required in the case of an
assignment or sublease to (i) any successor to Tenant by merger or acquisition
of substantially all of Tenant's assets or stock or (ii) any entity controlling,
controlled by or under common control with Tenant; provided, however, that, in
each such case, Landlord shall be notified in writing by Tenant of any such
assignment or sublease.

     In the event of any assignment or sublease it is understood and agreed that
one-half of all "Excess Rent" shall be paid by Tenant to Landlord provided,
however, that, in the case of any assignment or sublease permitted by the
preceding paragraph, no Excess Rent shall be due to Landlord (a) for any
assignment or sublease under clause (i) of the preceding paragraph or (b) in the
case of any assignment or sublease under clause (ii) of the preceding paragraph
for any period of time while the assignee or sublessee controls, is controlled
by or under common control with Tenant.  "Excess Rent" is defined as all amounts
paid to Tenant by an assignee or sublessee after deducting from such amounts the
Rent due for the space in the Leased Premises subject to such assignment or
sublease and reasonable and customary expenses actually paid by the Tenant in
connection with the such assignment or sublease (including, without limitation,
reasonable attorneys' fees and brokerage commissions, allowance and
inducements).

     The consent by Landlord to any assignment or sublease shall not be
construed as a waiver or release of Tenant from any and all liability for the
performance of all covenants and obligations to be performed by Tenant under
this Lease, nor shall the collection or acceptance of rent from any assignee or
sublessee constitute a waiver or release of Tenant from any of its liabilities
or obligations under this Lease.  Landlord's consent to any assignment or
sublease shall not be construed as a consent with respect to any subsequent
assignment or sublease.  The approval process for any subsequent assignment or
sublease shall be as set forth above.  For any period during which Tenant is in
default with respect to the payment of Rent, Tenant hereby assigns to 

                                      24
<PAGE>
 
Landlord the rent due from any assignee or sublessee of Tenant and hereby
authorizes each assignee or sublessee to pay said rent directly to Landlord.

Landlord shall give the Tenant a choice at the time Landlord is preparing to do
such duplicative or inconsistent work of either (i) having the Landlord perform
such work at the Landlord's cost at the Guaranteed Site Plan Work stage and then
having the Landlord perform the duplicative or inconsistent work at the
Alternate 1 Site Plan Work stage at the Tenant's cost (notwithstanding Section
                                                                       -------

deferred work shall automatically be deemed to be excluded for the purpose of
determining Substantial Completion and Landlord's compliance with Performance
Dates (notwithstanding Sections 16.9 or anything else contained in this Lease to

the contrary). If the Tenant chooses option (ii) above, the Tenant shall have
the right to later change its decision and give the Landlord written notice to
pursue option (i) instead but, in such a case, the work that had been deferred
will continue to be excluded for the purpose of determining Substantial
Completion and Landlord's compliance with Performance Dates.

      16.3.2  Landlord covenants and represents that the Work shall be

16.4  Architect, Plans and Specifications.
      ------------------------------------
Landlord and Tenant agree to use DiMella Shaffer as the architect for the Work
provided, however, that Landlord and Tenant each reserve the right to change, at
any time, to another architect reasonably acceptable to the other party if such
party desiring the change is not reasonably satisfied with DiMella Shaffer due
to a material default by DiMella Shaffer in the performance of its obligations.
The Base Building Improvements shall be performed pursuant to certain final
plans and specifications to be developed by Landlord and approved by Tenant
("Base Building Plans and Specifications") which approval shall not be
unreasonably withheld or delayed if said final plans are consistent with the
description and plans for the Base Building Improvements set forth in Exhibit C.
                                                                      --------- 
During the course of construction, any shop drawings, change orders or other
modifications which constitute a material change in the Base Building Plans and
Specifications must be approved by Tenant which approval shall not be
unreasonably withheld or delayed. The Tenant Work shall be performed pursuant to
certain plans and specifications to be developed by Tenant and approved by
Landlord (the "Tenant Work Plans and Specifications") which approval shall not
be unreasonably withheld or delayed if said final plans and specifications are
consistent with the description and plans for the Tenant Work set forth in
Exhibit C.  During the course of construction, any shop drawings, change orders
- ---------                                                                      
or other modifications which constitute a material change in the Tenant Work
must be approved by Landlord which approval shall not be unreasonably withheld
or delayed.  Landlord and Tenant agree to reasonably coordinate the Base
Building Improvements and the Tenant Work.  The Landlord and the Tenant agree to
use reasonable efforts to approve the final Base Building Plans and
Specifications by January 5, 1998 and the final Tenant Work Plans and
Specifications by February 15, 1998.

16.5  Selection of the Contractor.  The Landlord shall select the contractor to
      ----------------------------                                             
perform the Base Building Improvements and Tenant Work subject to the approval
of the Tenant which approval shall not be unreasonably withheld or delayed
provided, however, that Tenant may withhold approval if (i) the bid for the
Tenant Work submitted by the contractor selected by Landlord is higher than the
bid for the Tenant Work made by a contractor invited by Tenant to make a bid for
the Work and (ii) the total bid for all the Work is no higher than the total bid
for all the Work submitted by the contractor selected by the Landlord.  Tenant
shall be entitled to have access to all written bids, subcontractor lists,
pricing and other materials in Landlord's possession which are relevant to
Tenant making an informed decision regarding the selection of the contractor and
the Landlord will give the Tenant prior notice and a reasonable opportunity to
participate in all formal contractor interviews and meetings.  In the bids
submitted by contractors, the cost of the Tenant

Work must either be a fixed price or cost plus with a guarantied maximum and, in
either case, the change order pricing (i.e. overhead and profit on change
orders) must be specified in the bid approved by Tenant pursuant to this Section
                                                                         -------
16.5. Landlord and Tenant agree to use reasonable efforts to have a contractor
- -----
selected by Landlord and approved by Tenant by January 15, 1998 recognizing that
the selection and approval of the contractor will occur at a later date if the
final Tenant Work Plans and Specifications have not been approved prior to said
date. As stated in Section 16.4 above, the Landlord and the Tenant have agreed
                   ------------ 
to use reasonable efforts to approve the final Tenant Work Plans and
Specifications by February 15, 1998. The failure to so approve the final Tenant
Work Plans and Specifications by the earlier date of January 15, 1998 will not
be deemed to be a Tenant Delay. Tenant shall approve the final form of the
contract to be entered into with the selected contractor, which approval shall
not be unreasonably withheld or delayed.

16.6  Payment of Costs.
      ----------------  

      16.6.1  Payment of Costs of Work. For all of the Work, the Landlord agrees
              ------------------------ 
to pay for the following:


      (i)   all out-of-pocket costs and expenses incurred by Landlord to third
            parties for the architectural work, engineering work, construction
            and installation of the Base Building Improvements;

     (ii)   all out-of-pocket costs and expenses incurred by Landlord to third
            parties for the construction and installation of the Tenant Work
            (other than the Work described in (iii) below) up to a maximum
            aggregate amount for (i) and (ii) of One Million Six Hundred Eighty-
            Eight Thousand Four Hundred and 00/100 Dollars ($1,688,400.00)

    (iii)   As for any Work to be done in connection with the heating,
            ventilating and air conditioning system other than the Base Building
            Work, the Landlord and Tenant shall split the third party out-of-
            pocket costs and expenses incurred by Landlord for such work on a
            50/50 basis until Landlord and Tenant have each paid Fifty Thousand
            Dollars ($50,000.00) and, thereafter, Tenant shall be solely
            responsible for the payment of such costs and expenses for the
            remainder of said work. Tenant's portion of the cost of said work
            may be charged against the Tenant's Allowance.


Tenant agrees to pay for all cost and expenses of the Tenant Work in excess of
Tenant's Allowance.

     16.6.2   Invoices; Payments. Tenant may send invoices to Landlord for all

other amounts to be paid by Tenant for the Work,

                                      31
<PAGE>
 
Landlord shall bill Tenant for such amounts after Landlord has funded all of the
amounts to be paid by the Landlord pursuant to Section 16.6.1 above. Tenant
                                               --------------   
agrees to pay all such amounts promptly upon being billed therefor and such
amounts may be paid at one time or from time to time in separate payments if
Landlord so requests; provided that Tenant shall not pay for any work until it
is actually installed. It is agreed that all such amounts payable by Tenant in
connection with the Work shall be deemed Additional Rent under this Lease.


16.7  Tenant's Self-Funding Option. Notwithstanding anything contained herein to
      ----------------------------
the contrary, Tenant may elect, by sending written notice to Landlord within
thirty (30) days of the date that this Lease is executed by Landlord and Tenant,
to self fund the Tenant's Allowance; in which case, the annual rate of Base Rent
for the Original Term set forth in Section 3.2 above will be reduced by Two and
                                   -----------
11/100 Dollars ($2.11) per rentable square foot of the Leased Premises (with the
parties irrevocable agreeing that the Leased Premises contains 84,420 square
feet of rentable floor space).


16.8  Substantial Completion "Substantial Completion" shall be deemed to occur
      ----------------------
when Landlord has received a Certificate of Occupancy for the Building and a
certificate from the architect who has been overseeing the Work certifying that
the Guaranteed Site Plan Work (except for all Guaranteed Site Plan Work which
may have been deferred at the request of Tenant pursuant to Section 16.3 above)
                                                            ------------ 
has been substantially completed. A punch list shall be developed by Landlord
and Tenant, and all punch list items (except for any Guaranteed Site Plan Work
which may have been deferred at the request of Tenant pursuant to Section 16.3
above) shall be completed to the reasonable satisfaction of Tenant within 30
days of Substantial Completion subject to force majeure and Tenant Delays.


16.9  Performance Dates; Remedies.
      ----------------------------

      16.9.1  Performance Dates, Tenant Delay and Force Majeure Definitions. The
              ------------------------------------------------------------- 
"Permit Performance Date," "Substantial Completion Date," and "Outside Date" (as
those terms are defined below) are the "Performance Dates." "Tenant Delay" shall
mean any delay in the Guaranteed Site Plan Work caused, directly or indirectly,
by any act or omission of Tenant or anyone acting by or on behalf of Tenant
(including, without limitation, any architect or engineer in his or her capacity
of working for Tenant). If a delay in the Guaranteed Site Plan Work is caused by
Landlord and Tenant, only the portion of such delay attributable to the Tenant
shall constitute a Tenant Delay. "Force majeure" shall include all matters
beyond the reasonable control of Landlord but shall not include financial
difficulties of the Landlord or any Guarantor or work stoppages or strikes due
to non-payment by Landlord or the Guarantors. If the force majeure event is the
insolvency of the contractor or any subcontractor or material default by the
contractor or any subcontractor under its applicable contract or subcontract,
then the Landlord shall use reasonable efforts to replace the insolvent or
defaulting contractor or subcontractor. Landlord shall use reasonable efforts to
give the Tenant prompt written notice of any and all force majeure events and
Tenant Delays, and the Landlord cannot extend any calendar date set forth below
for a Performance Date because of force majeure or a Tenant Delay unless the
Landlord has given the

                                      32
<PAGE>
 
Tenant prompt written notice of the force majeure or Tenant Delay causing the
extension and, in any event, such notice shall be prior to the calendar date
which is being extended together with the Landlord's reasonable estimate of the
extension required because of the force majeure or Tenant Delay. Any extension
for force majeure or a Tenant Delay shall be only as long as is reasonably
necessary to compensate for the delay caused by the force majeure or Tenant
Delay.

      16.9.2  Scheduled Completion Date.  Landlord shall use  reasonable efforts
              -------------------------                                         
to achieve Substantial Completion  by September 1, 1998 or earlier if the Tenant
requests an earlier date and if Substantial Completion is not achieved by the
applicable date, the Landlord shall thereafter continue to use reasonable
efforts to achieve Substantial Completion unless and until the Lease is
terminated or the Tenant exercises the self-help right set forth in Section
                                                                    -------
16.9.4(b) below.  If Tenant requests an earlier date then Tenant shall be deemed
- ---------                                                                       
to have waived any right to wait until September 1, 1998 to have the Term
Commencement Date occur, Landlord shall be under no obligation to incur overtime
costs or any other special, additional or extraordinary costs to achieve
Substantial Completion by such earlier date, and such earlier date shall not
change the Performance Dates in any way.

      16.9.3  Permit Performance Dates. At the Landlord's sole cost and expense,
the Landlord shall (i) promptly file for and obtain by March 1, 1998, as such
date may be extended for Tenant Delays, (the "Base Building Permit Performance
Date") a building permit as required by the Town to construct the Guaranteed
Site Plan Work which is classified on Exhibit C as being Base Building
                                      ---------  
Improvement Work ( the "Base Building Permit"); and (ii) promptly file for and
obtain by March 31, 1998, as such date may be extended for Tenant Delays, (the
"Tenant Work Building Permit Performance Date") a building permit as required by
the Town to construct the Guaranteed Site Plan Work which is classified on
Exhibit C as being Tenant Work ( the "Tenant Work Building Permit"). The Base
- ---------
Building Permit and the Tenant Work Building Permit are hereinafter collectively
referred to as the "Building Permits." In addition, the Landlord shall, at the
Landlord's sole cost and expense, promptly file by January 30, 1998, as such
date may be extended for Tenant Delays, an application with the Planning Board
of the Town for the approval of the Alternate 1 Site Plan (the "Site Plan
Application Filing Date"). At the Landlord's sole cost and expense, the Landlord
shall use reasonably diligent efforts to have the Planning Board of the Town
approve the Alternate 1 Site Plan; such efforts to include, without limitation,
defending any appeal challenging the approval of the Alternate 1 Site Plan if
approval is given. Notwithstanding anything which may be construed to the
contrary, the Tenant acknowledges and agrees that the Site Plan Application
Filing Date is a filing date only and Landlord is not making any
representations, warranties or guaranties that the Alternate 1 Site Plan will be
approved by the Planing Board of the Town. The Base Building Permit Performance
Date, the Tenant Work Building Permit Performance Date, and the Site Plan
Application Filing Date are hereinafter collectively referred to as the "Permit
Performance Dates." The Tenant shall cooperate with the Landlord in obtaining
the Building Permits and the Planning Board's approval of the Alternate 1 Site
Plan. Without limiting the generality of the cooperation between Landlord and
Tenant, the Tenant agrees, promptly after each request from Landlord, to provide
Landlord with all information regarding Tenant and Tenant's operations as
Landlord may need to file for and obtain

                                      33
<PAGE>
 
the Building Permits and such other information, if any, needed for the approval
process for the Alternate 1 Site Plan. Notwithstanding the foregoing, the Tenant
shall not be liable for the payment of any costs or expenses in connection with
obtaining the Building Permits or applying for the approval of the Alternate 1
Site Plan. In the event that the Base Building Permit is not obtained by the
Base Building Permit Performance Date, the Tenant Work Building Permit is not
obtained by the Tenant Work Building Permit Performance Date, or the application
to approve the Alternate 1 Site Plan is not filed with the Planning Board of the
Town by the Site Plan Application Filing Date, then the Tenant shall have the
right to terminate this Lease by giving Landlord written notice of such
termination within fifteen (15) days of the Permit Performance Date which was
missed; whereupon the Landlord shall refund to the Tenant all pre-paid Base Rent
and pay all of the out-of-pocket architectural and engineering costs incurred by
the Tenant to third parties in connection with the Tenant Work as of the date of
said termination (including, without limitation, the fees of the architect,
DiMella Shaffer) and refund to Tenant all amounts (if any) that Tenant may have
paid to Landlord for the Work pursuant to Section 16.6.2 above; whereupon this
                                          --------------   
Lease shall terminate and the parties shall have no further recourse against one
another.

      16.9.4  Failure to Meet Substantial Completion Date.
              --------------------------------------------
      If Substantially Completion is not achieved by November 1, 1998 as such
date may be extended for force majeure and Tenant Delays (the "Substantial
Completion Date") then the Tenant shall have the right to elect to exercise one
of the following remedies by sending written notice to the Landlord and the
Guarantors within fifteen (15) days of the Substantial Completion Date:


      (a) to have the Landlord continue to construct the Work, in which case the
          Landlord must give a credit to the Tenant towards the payment of Base
          Rent. Such credit shall be two days' worth of free Base Rent (at the
          rate of Base Rent set for the first Lease Year) for each day after the
          Substantial Completion Date that Substantial Completion was not
          achieved for a reason other than force majeure or Tenant Delay; or

      (b) Tenant shall have the right (but not the obligation) to exercise self-
          help to complete the Work and Tenant shall have the right to offset
          against the payment of Base Rent the reasonable out-of-pocket costs
          and expenses incurred by Tenant to third parties in connection with
          the Tenant taking over the Landlord's obligation to complete
          construction and installation of the Work and interest on funds
          advanced by Tenant to pay for such costs and expenses at the rate of
          nine percent (9%) per annum but excluding all amounts which Tenant was
          to pay if Landlord performed the Work (the "Off-Set Amount").
          Notwithstanding the foregoing, Tenant agrees that Tenant's off-set
          right shall be limited so that in no event shall Tenant pay less Base
          Rent in any month than the lesser of the following: (a) the amount of
          Base Rent necessary to pay principal and interest payments to the
          holder of the first mortgage on the Leased Premises, if any, with a
          thirty (30) year amortization period at the interest rate being then
          charged by such holder pursuant to the loan documents 

                                      34
<PAGE>
 
         executed in connection with such first mortgage; and (b) Base Rent
         which will fully repay Tenant for the Off-Set Amount by the scheduled
         expiration of the Original Lease Term. Prior to Tenant off setting any
         amount of Base Rent, Tenant shall provide Landlord with written notice
         of the Off-Set Amount together with reasonably detailed documentation
         supporting the calculation of the Off-Set Amount. In addition, Tenant
         shall promptly provide Landlord with such other information regarding
         the calculation of the Off-Set Amount as Landlord may reasonably
         request from time to time and Landlord or an independent, certified
         public accountant designated by Landlord shall have the right, during
         regular business hours and after giving ten (10) days' advance written
         notice to Tenant, to inspect and audit Tenant's books and records
         relating to the Off-Set Amount. If as a result of such audit, it
         becomes clear that an error was made in the calculation of the Off-Set
         Amount, then an appropriate adjustment shall be made promptly. If
         Tenant exercises the self-help right set forth above, Landlord shall
         assign to Tenant all of Landlord's rights under and to all plans and
         specifications, construction contracts, architect contracts and all
         other contracts which Landlord has in connection with the Work subject
         to any prior rights which Landlord may have previously assigned to any
         mortgage lender.

If the Tenant fails to elect a remedy by the Substantial Completion Date as
aforesaid, then the Tenant shall be deemed to have elected the remedy set forth
in Subsection (a) above.  If the Tenant elects the self-help right set forth in
   --------------                                                              
subsection (b) as aforesaid, the Tenant shall not have any rights under
- --------------                                                         
subsection (a) above or under Section 16.9.5 or Section 16.9.6 below.
- --------------                --------------    --------------       


     16.9.5     Failure to Meet Outside Date because of Force Majeure.  If,
                -----------------------------------------------------     
because of force majeure, Substantial Completion is not achieved by March 1,
1999 as the same may be extended for Tenant Delays (the "Outside Date"), then
the Tenant shall have the right to terminate this Lease by giving Landlord
written notice of such termination within fifteen (15) days of the Outside Date;
whereupon the Landlord shall refund to the Tenant all pre-paid Base Rent, this
Lease shall terminate and the parties shall have no further recourse against one
another.  Notwithstanding the foregoing, this Section shall be null and void and
of no force and effect if Tenant elected the self-help right set forth above.



     16.9.6     Failure to Meet Outside Date for a Reason Other than Force
                ----------------------------------------------------------
Majeure or Tenant Delay.  If Substantial Completion is not achieved by the
- -----------------------                                                   
Outside Date for a reason other than force majeure (with Tenant Delays already
being taken into account to determine the Outside Date) then, in addition to the
Tenant's right to terminate the Lease and receive a refund of all pre-paid Base
Rent as set forth above, the Landlord shall refund to the Tenant all amounts
paid by the Tenant to the Landlord for the Work pursuant to Section 16.6.2 above
                                                            --------------      
and the Landlord shall pay damages to the Tenant which shall be liquidated
damages in an amount equal to two days' worth of Base Rent (with the Base Rent
amount being the amount set in this Lease for the first Lease Year) for each day
after the Substantial Completion Date up to and including the Outside Date that
Substantial Completion is not achieved for a reason other than force majeure
provided that 

                                      35
<PAGE>
 
Landlord had used reasonable efforts to achieve Substantial Completion and the
Guarantors have performed their obligations to pay for the portion of the Work
to be funded by the Landlord as set forth below. Notwithstanding the foregoing,
this Section shall be null and void and of no force and effect if Tenant elected
the self-help right set forth above.


16.10     Guaranty.   By signing in their individual capacities below, Lewis
          --------

require testing to ascertain whether or not there has been any release of
Hazardous Materials, then the reasonable costs thereof shall be reimbursed by
Tenant to Landlord upon demand as additional charges but only if the testing
shows a release or threat of release of any Hazardous Materials and such release
or threat of release is as a result of any act or omission of Tenant or any
person acting under Tenant. In addition, Tenant shall execute affidavits,

                       ARTICLE 19 - FIRST EXTENSION TERM
                                    --------------------

19.1      Provided the Lease is then in full force and effect and further
provided that Tenant is not then in default, beyond the expiration of any
applicable grace periods, under any of the terms, covenants or conditions of the
Lease on Tenant's part to be observed or performed, Tenant shall have the option
to extend this Lease and the Lease Term for a first extended term (the "First
Extension Term") of five (5) years commencing on the date next following the
last day of the Original Lease Term and ending, unless sooner terminated
pursuant to the terms, covenants or conditions of the Lease or pursuant to law,
on the day immediately preceding the fifth (5th) anniversary of the commencement
date of the First Extension Term, such option to be exercisable only by written
notice given by Tenant to Landlord at least nine (9) months prior to the
expiration of the Original Lease Term. If Tenant exercises such option in
accordance with the provisions and limitations of this Article, this Lease and
the Lease Term shall be extended for such term upon all of the then applicable
terms, covenants and conditions contained in this Lease, except that the Base
Rent for the entire First Extension Term shall be at an annual rate determined
as set forth below, it being understood that such Base Rent shall be payable in
equal monthly installments, in advance, just as in the case of the Original
Lease Term.

19.2      The Base Rent for the First Extension Term shall be at the greater of
(i) the Base Rent at the end of the Original Lease Term or (ii) ninety-five
percent (95%) of the then fair rental value for the Leased Premises for the
First Extension Term, to be determined as follows: Landlord shall provide Tenant
with Landlord's written designation of what it believes ninety-five percent
(95%) of the fair rental value to be, indicating the Base Rent to be charged for
the First Extension Term, such written designation to be sent to Tenant within
thirty (30) days after receipt by Landlord of

                                      38
<PAGE>
 
notice of Tenant's exercise of its option with respect to the First Extension
Term. If Tenant disagrees with Landlord's designation and if the parties are
otherwise unable to agree upon the fair rental value of the Leased Premises for
the First Extension Term, then Tenant may initiate the following arbitration
process to determine ninety-five percent (95%) of fair rental value ("Market
Rent") by sending written notice thereof to Landlord within thirty (30) days
after receipt of Landlord's written designation as to Market Rent. If Tenant
fails to initiate this arbitration process as aforesaid, time being of the
essence, then Landlord's designation of Market Rent (as set forth in Landlord's
notice) shall be conclusive. In order to be effective Tenant's notice to
Landlord initiating the arbitration process shall specify the name and address
of the person designated to act as an appraiser on its behalf. Within fourteen
(14) days after the designation of Tenant's appraiser, Landlord shall give
notice to Tenant specifying the name and address of the person designated to act
as an appraiser on its behalf. If Landlord fails to notify Tenant of the
appointment of its appraiser within the time above specified, then the
appointment of the second appraiser shall be made in the same manner as
hereinafter provided for the appointment of a third appraiser in a case where
two appraisers are appointed hereunder and the parties are unable to agree upon
such appointment. The two appraisers so chosen shall meet within ten (10) days
after the second appraiser is appointed, and if, within fifteen (15) days after
the second appraiser is appointed, the two appraisers shall not agree upon a
determination, they shall together appoint a third appraiser. In the event of
their being unable to agree upon such appointment within fifteen (15) days after
the appointment of the second appraiser, the third appraiser shall be selected
by the parties themselves if they can agree thereon with a further period of
fifteen (15) days. If the parties do not so agree, then either party, on behalf
of both and on notice to the other, may request such appointment by the American
Arbitration Association (or any organization successor thereto) in accordance
with its rules then prevailing.

Each party shall pay the fees and expenses of the one of the two original
appraisers appointed by or for such party, and the fees and expenses of the
third appraiser and all other expenses (not including the attorneys fees,
witness fees and similar expenses of the parties which shall be borne separately
by each of the parties) of the arbitration shall be borne by the parties
equally.


     If a third appraiser is chosen as provided above, then the three appraisers
shall collectively determine the Market Rent as provided in the last paragraph
of this Section and render a written certified report of their determination to
both Landlord and Tenant within fifteen (15) days after appointment of the third
appraiser if such third appraiser is appointed pursuant to this Section.


     Each of the appraisers selected as herein provided shall be real estate
brokers or appraisers and shall have at least ten (10) years experience in the
leasing and renting of office space in first class office buildings in Middlesex
County.  In addition, the third appraiser (if any) shall be an independent party
not affiliated in any way with either Landlord or Tenant.


     Each of the three appraisers shall indicate his view of ninety-five percent
(95%) of the fair rental value.  The number furthest from the middle number
shall be disregarded and the remaining 

                                      39
<PAGE>
 
two numbers shall be averaged. The resulting average shall be deemed to be
ninety-five percent (95%) of the fair rental value for purposes of this
paragraph. If the middle number is equidistant from the two other numbers, the
middle number shall be deemed to be ninety-five percent (95%) of the fair rental
value for the purposes of this paragraph. Tenant may cancel its exercise of this
option to extend the term of this Lease, if Tenant is dissatisfied with the
determination of Market Rent through the foregoing arbitration process. In order
to cancel its exercise of this option as aforesaid, Tenant must send written
notice to Landlord within seven (7) days after the determination by the
appraisers of Market Rent, and in such notice Tenant must state that it is so
canceling its exercise of this extension option.


19.3      Time is of the essence with respect to the exercise of the option
contained herein. Tenant shall not have the right to give any notice exercising
such option after the expiration of the applicable time limitation set forth
herein, and any notice given after such time limitation purporting to exercise
such option shall be void and of no force or effect.


                       ARTICLE 20 - SECOND EXTENSION TERM
                                    ---------------------

20.1      Provided the Lease is then in full force and effect and further
provided that Tenant is not then in default, beyond the expiration of any
applicable grace periods, under any of the terms, covenants or conditions of
this Lease on Tenant's part to be observed or performed, Tenant shall have the
option to extend this Lease and the Lease Term for a second extended term (the
"Second Extension Term") of five (5) years commencing on the date next following
the last day of the First Extension Term and ending, unless sooner terminated
pursuant to the terms, covenants or conditions of the Lease or pursuant to law,
on the day immediately preceding the fifth (5th) anniversary of the commencement
date of the Second Extension Term, such option to be exercisable only by written
notice given by Tenant to Landlord at least nine (9) months prior to the
expiration of the First Extension Term.

20.2      If Tenant exercises such option in accordance with the provisions and
limitations of this Article, this Lease and the Lease Term shall be extended for
such term upon all of the then applicable terms, covenants and conditions
contained in this Lease, except that the Base Rent for the entire Second
Extension Term shall be at an annual rate determined as set forth below, it
being understood that Base Rent shall be payable in equal monthly installments,
in advance, just as in the case of the Original Lease Term.  The Base Rent for
the Extension Term shall be at the greater of (i) the Base Rent at the end of
the First Extension Term or (ii) ninety-five percent (95%) of the then fair
rental value for the Leased Premises for the Second Extension Term, to be
determined as follows:  Landlord shall provide Tenant with Landlord's written
designation of what it believes ninety-five percent (95%) of the fair rental
value to be, indicating the Base Rent to be charged for the Second Extension
Term, such written designation to be sent to Tenant within thirty (30) days
after receipt by Landlord of notice of Tenant's exercise of its option with
respect to the Second Extension Term.  If Tenant disagrees with Landlord's
designation and if the parties are otherwise unable to agree upon ninety-five
percent (95%) of the fair rental value of the Leased Premises for 

                                      40
<PAGE>
 
the Extension Term, then Tenant may initiate the following arbitration process
to determine ninety-five percent (95%) of fair rental value ("Market Rent") by
sending written notice thereof to Landlord within thirty (30) days after receipt
of Landlord's written designation as to Market Rent. If Tenant fails to initiate
this arbitration process as aforesaid, time being of the essence, then
Landlord's designation of Market Rent (as set forth in Landlord's notice) shall
be conclusive. In order to be effective Tenant's notice to Landlord initiating
the arbitration process shall specify the name and address of the person
designated to act as an appraiser on its behalf. Within fourteen (14) days after
the designation of Tenant's appraiser, Landlord shall give notice to Tenant
specifying the name and address of the person designated to act as an appraiser
on its behalf. If Landlord fails to notify Tenant of the appointment of its
appraiser within the time above specified, then the appointment of the second
appraiser shall be made in the same manner as hereinafter provided for the
appointment of a third appraiser in a case where two appraisers are appointed
hereunder and the parties are unable to agree upon such appointment. The two
appraisers so chosen shall meet within ten (10) days after the second appraiser
is appointed, and if, within fifteen (15) days after the second appraiser is
appointed, the two appraisers shall not agree upon a determination, they shall
together appoint a third appraiser. In the event of their being unable to agree
upon such appointment within fifteen (15) days after the appointment of the
second appraiser, the third appraiser shall be selected by the parties
themselves if they can agree thereon with a further period of fifteen (15) days.
If the parties do not so agree, then either party, on behalf of both and on
notice to the other, may request such appointment by the American Arbitration
Association (or any organization successor thereto) in accordance with its rules
then prevailing.


     Each party shall pay the fees and expenses of the one of the two original
appraisers appointed by or for such party, and the fees and expenses of the
third appraiser and all other expenses (not including the attorneys fees,
witness fees and similar expenses of the parties which shall be borne separately
by each of the parties) of the arbitration shall be borne by the parties
equally.


     If a third appraiser is chosen as provided above, then such the three
appraisers shall collectively determine the Market Rent as provided in the last
paragraph of this Section and render a written certified report of their
determination to both Landlord and Tenant within fifteen (15) days after
appointment of the third appraiser if such third appraiser is appointed pursuant
to this Section.


     Each of the appraisers selected as herein provided shall be real estate
brokers or appraisers and have at least ten (10) years experience in the
leasing and renting of office space in first class office buildings in Middlesex
County.  In addition, the third appraiser (if any) shall be an independent party
not affiliated in any way with either Landlord or Tenant.


       Each of the three appraisers shall indicate his view of ninety-five
percent (95%) of the fair rental value.  The number furthest from the middle
number shall be disregarded and the remaining two numbers shall be averaged.
The resulting average shall be deemed to be ninety-five 

                                      41
<PAGE>
 
percent (95%) of the fair rental value for purposes of this paragraph. If the
middle number is equidistant from the two other numbers, the middle number shall
be deemed to be ninety-five percent (95%) of the fair rental value for the
purposes of this paragraph. Tenant may cancel its exercise of this option to
extend the term of this Lease, if Tenant is dissatisfied with the determination
of Market Rent through the foregoing arbitration process. In order to cancel its
exercise of this option as aforesaid, Tenant must send written notice to
Landlord within seven (7) days after the determination by the appraisers of
Market Rent, and in such notice Tenant must state that it is so canceling its
exercise of this extension option.


20.3      Time is of the essence with respect to the exercise of the option
contained herein. Tenant shall not have the right to give any notice exercising
such option after the expiration of the applicable time limitation set forth
herein, and any notice given after such time limitation purporting to exercise
such option shall be void and of no force or effect.


                       ARTICLE 21 - RIGHT OF FIRST OFFER
                       ---------------------------------

          Provided Tenant is not then in default, beyond the expiration of any
applicable grace periods, under any of the terms, covenants or conditions of the
Lease on Tenant's part to be observed or performed, it is agreed that if, at any
time during the Lease Term, Landlord decides to offer the Property for sale to
any third (3rd) party (which does not include any affiliate of Landlord or any
party controlled by or under common control with Landlord), then Landlord will
provide Tenant with a right of first offer, as follows:

          Landlord will provide Tenant with written notice (the "Notice of
          Sale") indicating that Landlord plans to offer the Property for sale
          and setting forth the terms on which Landlord intends to offer the
          Property for sale. The terms which Landlord will communicate to Tenant
          shall include at least the purchase price which Landlord intends to
          ask, the general time frame during which the sale is to be consummated
          and such other terms as Landlord has determined at that time shall be
          incorporated into the sales arrangements. Tenant shall have the right
          for five (5) business days from its receipt of Landlord's written
          Notice of Sale to provide Landlord with written notice ("Tenant's
          Notice of Election to Purchase") indicating its election to purchase
          the Property on the terms being offered by Landlord. Landlord and
          Tenant then will have a second (2nd) five (5) business day period to
          execute a Purchase and Sale Agreement formalizing the obligations of
          both parties on terms and conditions acceptable to both of them.


          If Landlord does not receive Tenant's written Notice of Election of
Purchase within five (5) business days after Tenant's receipt of Landlord's
Notice of Sale, or if both Landlord and Tenant have not both signed a Purchase
and Sale Agreement for the purchase and sale of the Property within ten (10)
business days after Tenant's receipt of Landlord's Notice of Sale, then, in
either of such events, Landlord shall be free to offer the Property to any other
prospective purchasers and to negotiate with them with respect to any and all
terms and conditions of sale (including without limitation the purchase price),
and thereafter Landlord shall be free to sell to any other purchaser the

                                      42
<PAGE>
 
Property on any terms and conditions, free of any claim by Tenant (provided only
that Landlord's dealings with Tenant had been in good faith).

          the Premises), and has as its denominator the total Rentable Area of
          the Building, whether rented or not, subject only to the adjustments
          which follow. The total Rentable Area of the Building shall be
          calculated as if the Building were entirely occupied by Tenants
          renting full floors. The calculation of the total Rentable Area of the
          Building, whether rented or not, shall be determined on completion of
          the Building and shall be adjusted from time to time to give effect to
          any structural or functional change effecting same. The calculation of
          the Rentable Area of the Premises shall be adjusted from time to time
          to give effect to any change therein during the Term.

          (b)  "Rentable Area" in the case of a whole floor of the Building
          shall include all area with the outside Building walls and shall be

          walls without deduction for columns and projections necessary to the
          building but shall not include stairs and elevators shafts provided by
          the Landlord for use in common with other Tenants.

          (c)  Rentable Area in the case of a part of the floor of the Building
          shall include all area occupied by the Tenant and shall be computed by
          measuring from the outside surface of the outside Building walls to
          the outside surface of corridors or other permanent

                                       3
<PAGE>
 
          partitions and to the centre of partitions which separate the area
          occupied by the Tenant from adjoining Rentable Areas without deduction
          for columns and projections necessary to the Building but shall not
          include stairs and elevator shafts supplied by the Landlord for use in
          common with other Tenants within the area occupied. The Rentable Area
          of the Premises (as calculated in accordance with the foregoing
          formula shall be increased (such increase being referred to in this
          lease as the "Additional Area") by the fraction of the total area of
          the corridors, elevator lobbies, service elevator lobbies, toilets,
          air conditioning rooms, fan rooms, janitors' closets, telephone and
          electrical closets and other closets serving the Premises in common
          with other Premises, if any, on such floor, which fraction has as its
          numerator the Rentable Area for the Premises (calculated in accordance
          with the foregoing formula) and has as its denominator the sum of the
          Rentable Areas (prior to the inclusion of the additional area) of such
          floor. The lobbies and entrances on the main floor and any other
          floor(s) and subservice floors used in common by Tenants shall be
          excluded from the foregoing calculations. The "Additional Area" shall
          not be utilized in determining the Rentable Area of the Premises for
          purposes of establishing basic annual rent under the provisions of
          Paragraph 3 hereof.

          (d)  In determining the Proportionate Share, the Net Rentable Area,
          the Rentable Area or the total Rentable Area of the Building, the
          Landlord's architect's certificate in that regard shall be final and
          binding upon the parties hereto.

event provide for a Rent plus percentage  rent, if any, in an amount less than
the Rent, for the last year of the Term, which is Five ($5.00) Dollars plus the
balance of amortized leasehold costs.  Pending agreement of the parties as to,
or as to the determination by arbitration of the Renewal Rent, Tenant shall
continue to pay the Rent for the 

                                      23

<PAGE>
 
last year of the Term, and upon agreement or determination by arbitration as
aforesaid shall commence to pay the Renewal Rent retroactive to the commencement
of the renewal term. Any underpayment by the Tenant shall be adjusted
retroactive to the commencement of the renewal term.

          If the Tenant after Five (5) years does not wish to renew the lease,
then all of the unpaid portion of their leasehold improvements, in accordance
with the payment schedule attached herewith and defined as Schedule "B" shall
become due and payable immediately.

26.       ADJACENT SPACE

          The Landlord agrees to provide the Tenant with the opportunity to
lease Suite #110 comprising approximately One Thousand, Six Hundred and Five
(1,605) square fee, at such time as the space becomes available for rental.  The
current lease for Suite #110 expires on October 31st, 1998.  The lease includes
an option to renew for a further term of Two (2) Years expiring on October 31st,
2000.  The Landlord will not allow any further options to renew to this lease,
unless Lifeline Systems (Canada) Inc. does not wish to lease Suite #110 at that
time.  Upon receipt of notice from the Landlord or impending availability of
Suite #110, the Tenant will have thirty (30) days to decide.  Upon the
expiration of the thirty days after notice no further notification will be
required and if the Tenant has not indicated its binding intention to lease
within such time then this right of "opportunity to lease" shall lapse and be of
no further effect.

27.       LEASE ENTIRE AGREEMENT

warranties, agreements or conditions expressed or implied, collateral or
otherwise forming part of or in any way affecting or relating to this Lease save

form part, by way of mortgage, and the Tenant hereby covenants and agrees that
it will promptly, at any time and from time to time, as required by the Landlord
during the Term hereof, execute all documents and give all further assurances to
this proviso as may be reasonably required to effectuate the postponement of its

                                MASTER AGREEMENT
                                      for
                             PROFESSIONAL SERVICES
- --------------------------------------------------------------------------------


     This Master Agreement ("Agreement") dated ___June 16_____________, 1997 is
entered into between:


               "Cambridge"                     And  "Client"


          Cambridge Technology Partners             Lifeline Systems, Inc.
          -----------------------------             ----------------------
          304 Vassar Street                         640 Memorial Drive
          -----------------                         ------------------
          Cambridge, MA  02139                      Cambridge, MA 02139
          --------------------                      -------------------

This Agreement describes the terms and conditions under which Cambridge will
provide professional services for Client and supersedes all prior written and
oral understandings between Cambridge and Client.  Services will be authorized
via Work Orders issued pursuant to this Agreement.

1.  WORK ORDERS
- ---------------

Individual service engagements performed under this Agreement will be defined by
a Work Order in the form of Exhibit A.  Work Orders will include a description
of the services to be provided, pricing, payment schedule, special terms and
conditions applicable to the specific Work Order and a Statement of Work (a
Statement of Work outline is provided as Exhibit B; hereafter, each Work Order
and related Statement of Work are referred to collectively as a "Work Order").
Each Work Order, together with the terms of this Agreement, is a separate
contract that will be effective as of the date signed by authorized
representatives of both Cambridge and Client.  If any terms of the Work Order
(including the Statement of Work) conflict with the terms of this Agreement, the
terms of the Work Order will take precedence.  If any term or provision of this
Agreement, or any Work Order, is held invalid or unenforceable for any reason,
the remainder of the provisions of this Agreement and/or Work Order will
continue in full force and effect.

2.  EXPENSES
- ------------

In addition to the price identified within each Work Order, Client is
responsible for the following documented expenses incurred by Cambridge while
performing services under this Agreement which have been pre-approved by Client
and which are in accordance with Client's internal expense reimbursement
guidelines:  (a) reasonable travel and living expenses of Cambridge personnel,
including but not limited to airfare, mileage, parking, tolls, lodging, auto
rental and per diem, (b) computer communication expenses, (c) shipping expenses
and (d) cost of third party hardware and software.  Notwithstanding the
foregoing, except as otherwise set forth in the 

                                       1
<PAGE>
 
applicable Work Order, Client shall not be liable for any expenses of Cambridge
in connection with a project in excess of 18% of the fixed project cost stated
on the applicable Work Order. Payment for expenses is due 30 days following
receipt of Cambridge's invoice.

3.  INVOICES
- ------------

Unless otherwise indicated in a Work Order, invoices for services and expenses
shall be rendered semi-monthly, or upon completion of the services if the
duration of the Work Order is less than one month.  Invoices shall be payable
upon receipt and sent to:

               Organization:      Lifeline Systems, Inc.
               Street Address:    640 Memorial Drive
               City, State, Zip:  Cambridge, MA  02139
               Attention:         Richard M. Reich

4.  CHANGES
- -----------

(a)  Neither this Agreement, nor any Work Order, may be modified or amended
     except via written change order signed by an authorized representative of
     both parties (a "Change Order").  If Client requests or Cambridge
     recommends changes during performance of a Work Order, Cambridge will
     provide Client with a written change order proposal setting forth (a) a
     description of the proposed change(s), (b) impact on price, (c) impact on
     production schedule and (d) a proposed revision of the Statement of Work.
     Client may, at its discretion, accept or reject the change order proposal.
     A change order proposal will be considered rejected if Client does not
     respond to the proposal within ten business days.  If accepted, Change
     Orders will be effective upon execution by both parties.

(b)  Notwithstanding the above, Cambridge may, after consultation with Client,
     make minor modifications to software design specifications if such
     modifications do not limit, diminish or affect the functional operation or
     use of the software or its output, increase Client expense or delay the
     production schedule.

5.  DELAYS
- ----------

If Cambridge notifies Client in writing that any phase of a Work Order will be
extended because Client materially failed to meet its responsibilities
identified within the Work Order, such delay will constitute a change and,
unless Client instructs Cambridge not to perform such work, Client will pay
Cambridge's standard time and material rates for the extended work (which costs
and fees shall in the aggregate be reasonable).  In no other case will Client be
responsible for increased costs or fees resulting from the delay or extension of
any project or service provided by Cambridge.

                                       2

6.  CONTINUATION OF SERVICES
- ----------------------------

In order to maintain the rapid timeframes of a project, it is important to
ensure the continuity from one project phase to the next.  To prevent impact to
a project, it may be necessary for Cambridge to continue into the next phase
even if all project related issues have not been fully resolved.  An Interim
Agreement in the form of Exhibit C allows Cambridge to maintain the project team
and begin work on the next phase of a project prior to the execution of a formal
Work Order.  Under an Interim Agreement duly executed by both parties, Client
pays Cambridge for the services in two week increments plus travel and living
expenses.  The Work Order, once in place, will supersede the Interim Agreement
and payments made under the Interim Agreement will be applied to the price
specified in the Work Order.

7.  CONFIDENTIALITY
- -------------------

Each party acknowledges that information provided by either party in connection
with this Agreement may contain confidential and proprietary data, and
disclosure of such information may be damaging to the disclosing party.  During
the performance of services under this Agreement it may be necessary for either
party to provide the other with certain information considered to be proprietary
or confidential by the disclosing party.  Cambridge and Client, their
successors, assignees, officers, directors, employees and agents, agree that
such information will be provided subject to the following terms and conditions:


(a)  The term "Information", as used in this section, denotes any and all
     technical and business information disclosed in any manner or form
     including, but not limited to financial plans and records, marketing plans,
     business strategies, trade secrets, present and proposed products, computer
     software programs, source code, relationships with third parties, customers
     lists, information regarding customers and suppliers, founders, employees,
     and affiliates.

(b)  Information of the disclosing party will be protected from disclosure to
     anyone other than the directors, officers, employees, consultants and
     contractors of the receiving party who have a need to have access to such
     Information to perform obligations or exercise rights under this Agreement
     and who are obligated to maintain the confidentiality of such Information.
     Each party will use the same degree of care to protect Information of the
     other party as it uses to protect its own Information of like importance,
     but no less than a reasonable degree of care.

(c)  The disclosing party's Information will be used only as necessary for
     performance of the receiving party's obligations under the applicable Work
     Order.  Neither party will make more copies of the Information than are
     necessary.

(d)  The receiving party will not have any obligation with respect to any
     Information of the 

                                       3
<PAGE>
 
     disclosing party which the receiving party can establish:

     (i)   is or becomes publicly available through no wrongful act of the
           receiving party;

     (ii)  was lawfully obtained by the receiving party from a third party
           without any obligation to maintain the Information as proprietary or
           confidential;

     (iii) was previously known to the receiving party without any obligation
           to keep it confidential; or

     (iv)  was independently developed by the receiving party without reference
           to or reliance on the Information.

     Notwithstanding the exceptions contained in Sections 7(d)(iii) and (iv)
     above, the Custom Software and all related source code, designs,
     documentation and materials shall constitute the confidential Information
     of Client.

(e)  No license to either parties' Information is either granted or implied by
     the disclosure of Information.

(f)  Within 14 days of a request by the disclosing party the receiving party
     shall return all property including but not limited to documents, records,
     tapes, and any other media as well as all copies thereof in its possession
     or under its control that contains Information of the disclosing party,
     except, with respect to Information of Cambridge, to the extent such
     Information is incorporated in a Deliverable.

(g)  The duties and obligations to protect Information will survive termination
     of this Agreement.

(h)  The parties recognize and acknowledge that the Information may have
     competitive value and that irreparable damage might result to the
     disclosing party if Information is improperly disclosed by the receiving
     party to any non-authorized third party.  The parties agree that legal
     proceedings at law or in equity, including injunctive relief, may be
     appropriate in the event of a breach hereof.

8.  OWNERSHIP (GENERAL)

     Order shall belong exclusively to Client, and Cambridge shall have no right
     to utilize such material for its own use.  Cambridge shall retain ownership
     of any pre-existing Cambridge materials (such as Training Materials)
     identified in writing as such under any Work Order.  Cambridge grants to
     Client a perpetual, worldwide, non-exclusive, non-transferable license, at
     no additional charge, to use such pre-existing materials for Client's

                                       4
<PAGE>
 
     internal business purposes only (it being understood that the foregoing
     shall not apply to Cambridge Components-In, which are subject to Exhibit D
     below).  Access to such pre-existing materials will be restricted to
     Client's employees, contractors, agents and consultants who are obligated
     to maintain the confidentiality of such materials.

(b)  Cambridge shall retain all rights in its proprietary methodologies for
     delivery of its Scoping, Rapid Solutions Workshop, Software Design and
     Development and Package Implementation services ("Methodology") which may
     be used by Cambridge and/or provided by Cambridge to Client during the
     course of a Work Order.  Client agrees to hold Cambridge's methodologies in
     confidence in accordance with the Confidentiality clause of this Agreement.

9.  OWNERSHIP (SOFTWARE)
- ------------------------

The categories of software associated with an application development project,
including software ownership and license rights, are defined below.


(a)  Custom Software:  Software developed or created by Cambridge for Client
     under a Work Order, excluding Third Party Software, Cambridge Components-In
     and Cambridge Components-Out.  Custom Software is owned by the Client.
     Cambridge hereby assigns all rights, title and interest in Custom Software
     to Client, as it is developed.

(b)  Third Party Software:  Pre-existing software components owned by a third
     party and used in developing the Client software application.  Third Party
     Software is generally licensed directly from the Third Party to Client.
     Cambridge will not use Third Party Software in connection with the
     performance of services hereunder without the written consent of Client.

(c)  Software Re-Use:  Employing a pre-existing software component as a building
     block when developing a software application.  A detailed explanation of
     Cambridge's Software Re-Use Program is provided in Exhibit D.  For purposes
     of this Agreement, no components will be classified as Cambridge
     Components-In or Cambridge Components-Out.  In the event the parties agree
     to amend this Agreement to provide for "Components-In" or "Components-Out",
     this Agreement will also be amended to provide for mutually agreeable
     license terms relating thereto.

     (i)  Cambridge Components-In:  Pre-existing Cambridge software components
          (or software developed by Cambridge staff not directly involved in
          Client's project) used by Cambridge as a development building block in
          the Client software application.

     (ii) Cambridge Components-Out:  Re-usable Cambridge software components
          created 

                                       5
<PAGE>
 
          during development of the Client software application. A software
          component will be deemed to be a "Component-Out" only when Cambridge
          and Client have agreed to classify it as such and have acknowledged
          this classification in a signed Work Order.

10.  ACCEPTANCE OF DELIVERABLES
- -------------------------------

(a)  Cambridge shall deliver software, documentation and other materials called
     for in the Statement of Work (the "Deliverables") to Client in accordance
     with the schedules set forth in the applicable Work Order.  Software will
     be delivered in executable object code form and fully commented source code
     form.

(b)  Deliverables will be deemed to have been accepted upon successful
     completion of the Acceptance Testing performed at the end of the
     Development Phase defined in the applicable Work Order.  The Acceptance
     Testing procedure will be established jointly by Cambridge and Client
     during the Development Phase.  The "success" of Acceptance Testing shall be
     evidenced by the Client's execution and delivery of the User Acceptance
     Test document related thereto.  The purpose of this Acceptance Testing is
     to determine if the Deliverables conform to their documentation and the
     Specifications developed during the Design Phase.   If Deliverables do not
     so conform, Cambridge will use its best efforts (including devoting all
     necessary resources) to cause such software to so conform as soon as
     possible.  If Cambridge is unable to cause such software to so conform
     within thirty (30) days after receipt of notice by Cambridge of such non
     conformance (or such additional cure period as Client may authorize instead
     of thirty days), Client shall have the right to terminate the Work Order.
     In such event, Cambridge will turn over to Client the Deliverables and all
     other works in progress "as is" and Cambridge and Client will negotiate in
     good faith to determine the value of the services and/or deliverables
     provided to Client.

11.  WARRANTIES
- ---------------

(a)  Cambridge will, at no additional charge to Client, correct Errors reported
     by Client during the Warranty Period unless otherwise specified in the
     applicable Work Order.  An Error is defined as an error in a Deliverable
     that prevents the Deliverable from performing in conformance with the
     specifications.  This warranty covers only corrections to problems with a
     Deliverable as designed and developed by Cambridge, in accordance with the
     Specifications, and does not cover Cambridge's efforts to perform
     enhancements or activities other than the correction of Errors.
     Additionally, this warranty does not cover problems caused by third party
     software or hardware products, or problems that result from software
     changes made by Client without the approval of Cambridge.  If, as a result
     of service calls placed under this warranty, Cambridge devotes staff time
     investigating problems that turn out to be problems other than Errors,
     Client will reimburse Cambridge, 

                                       6
<PAGE>
 
     on a time and materials basis, for such staff time. Cambridge will make
     every reasonable effort to minimize and/or mitigate any such additional
     charges to Client.

(b)  Cambridge further warrants that it will test, as part of its acceptance
     testing procedure, using commercially available software, all Deliverables
     for computer viruses, trojan horse, worm, time-out or other harmful or
     malicious code.  Cambridge also warrants, subject to the warranty
     restrictions contained in Section 11(a) above, that at the time of
     delivery, such Deliverables shall not experience any problems associated
     with the change of year from calendar year 1999 to 2000.

12.  INDEMNIFICATION
- --------------------

(a)  Cambridge shall indemnify, defend and hold Client harmless from and against
     any losses, damages, settlements, costs and expenses (including reasonable
     attorneys' fees) arising from any claim that a Deliverable infringes or
     violates any patent, copyright, trademark, trade secret or other
     intellectual or industrial property right of any third party.

(b)  Client shall notify Cambridge promptly in writing of any third party action
     (and provide information regarding all prior related claims) brought
     against Client based on a claim described in Section 12(a) above.
     Cambridge shall defend such action at its expense and pay all expenses and
     costs attributable to such claim incurred by Client (as they are incurred),
     and all settlements and damages awarded against Client in such action or
     settlement.  Cambridge shall have sole control of the defense of any such
     action and all negotiations for its settlement or compromise. Client shall
     reasonably cooperate with Cambridge in the defense of such claim, and may
     be represented, at Client's expense, by counsel of Client's selection.

(c)  In the event that an injunction or restraint is obtained against Client's
     use of the Deliverables by reason of infringement or violation of any
     patent, copyright, trade secret, trademark or other intellectual or
     industrial property right, then Cambridge shall, using best efforts and as
     soon as possible following the entry of such injunction or restraint, at no
     charge to Client, either (i) procure for Client the right to continue to
     use the Deliverables for their intended purposes or (ii) replace or modify
     the Deliverables so that it or they become non-infringing (so long as their
     functionality is essentially unchanged).

(d)  The provisions of Section 12(a)(1) notwithstanding, Cambridge shall not
     have any liability to Client to the extent that any claim of infringement
     is based upon (a) use of the Deliverables in conjunction with any data,
     equipment or software not provided, recommended or authorized by Cambridge,
     where the Deliverable would not itself be infringing or otherwise the
     subject of the claim or (b) any modification to the Deliverables not made
     or approved by Cambridge.

13.  TERM AND TERMINATION
- -------------------------

(a)  This Agreement shall remain in effect until terminated in writing by either
     party; provided that no such termination shall relieve either party of
     their respective obligations under any Work Order in effect at the date of
     termination of this Agreement.

(b)  Notwithstanding the foregoing, and without limiting such party's rights at
     law or in equity, either party may terminate this Agreement, and all
     existing Work Orders, if the other party has materially breached this
     Agreement or any Work Order and, except as set forth in the next sentence,
     such breach has not been cured within thirty (30) days following notice
     thereof by the other party.

(c)  Notwithstanding the foregoing, Client may, at any time, terminate work
     under a Work Order by providing Cambridge with a 30-day written termination
     notice.  The 30-day notice period will start upon Cambridge's receipt of
     the notice.  In the event of such termination, Cambridge will cease work
     immediately upon receipt of the written notice, and turn over to Client the
     Deliverables and all work in progress and Cambridge and Client will
     negotiate in good faith to determine the value of the services and/or
     deliverables provided to Client and reasonable compensation to Cambridge
     for such 30-day notice period.

(d)  Upon termination of this Agreement, all rights and obligations of the
     parties shall immediately terminate, except as follows:

     SECTION 12 ABOVE.

(b)  EXCEPT AS STATED IN THIS AGREEMENT, CAMBRIDGE MAKES NO OTHER WARRANTIES
     EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY WARRANTIES AS TO
     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

                       CAMBRIDGE SOFTWARE RE-USE PROGRAM


1.  WHAT IS CAMBRIDGE SOFTWARE RE-USE
- -------------------------------------

Cambridge uses the technique of "Software Re-Use" whenever the Client agrees it
is the most cost-effective development approach.  Cambridge defines Software Re-
Use as "using a pre-existing software component as a building block when
developing a customized software application".

The Cambridge Software Re-Use Program has the following benefits for the Client:

  a)  Shorter Delivery Time than would be possible if every line of code were
      ---------------------                                                  
written from scratch.

  b)  Greater Software Reliability because the pre-existing software has already
      ----------------------------                                              
been used and tested.

  c)  Greater Potential for Subsequent Re-Use by the Client because the finished
      -----------------------------------------------------                     
      software delivered to the Client is designed and developed with Software
      Re-Use in mind.

  d)  Free "Re-Usable Component" Updates for One Year.  Cambridge continues to
      -----------------------------------------------                         
      improve Components as they are used in other projects. For a period of one
      year after the Client's development is complete, Cambridge provides the
      Client with any update releases to those reusable software components.
      This free service includes updates to both the re-usable components
      created during development as well as the re-usable components Cambridge
      brings to the development effort.

2.  CAMBRIDGE SOFTWARE RE-USE TERMINOLOGY
- -----------------------------------------

  a)  Third Party Software Components - Any pre-existing software owned by a
      -------------------------------                                       
      third party and used in developing the Client software application. Third
      Party Software is typically licensed directly between the Third Party and
      the Client. Cambridge will not use Third Party Software in connection with
      the performance of services for Client without the written consent of
      Client.

  b)  Cambridge Components-In - Any pre-existing Cambridge software (or software
      -----------------------                                                   
      developed by Cambridge staff not directly involved in the Client's
      project) which is used by 

                                      16
<PAGE>
 
      Cambridge as a development building block in the Client's software
      application. Components-In are owned by Cambridge.

  c)  Cambridge Components-Out - Re-usable software components created during
      ------------------------                                               
      development of the Client's software application.  A component will be
      defined as a "Component-Out" only when the Client has agreed in writing to
      classify it as a Component-Out.

  d)  Custom Software - All software developed and delivered by Cambridge
      ---------------                                                    
      excluding the Third Party Software, Cambridge Components-In, and 
      ---------
      Cambridge-Components-Out. The Client retains ownership of the Custom
      Software, and Cambridge shall retain no rights therein.

3. PROCESS FOR IDENTIFYING "COMPONENTS-IN" AND "COMPONENTS-OUT"
- ----------------------------------------------------------------
All Components-In and Components-Out will be identified on individual Work
Orders.  Since it is often not possible to identify all components until after a
Work Order has been signed and the project underway, the component list can be
amended any time by a Change Order signed by both Cambridge and Client.
Software will not be included in the Re-Use Program without the Client's written
consent.

4.  NO "COMPONENTS-IN" OR "COMPONENTS-OUT"
- ------------------------------------------
For purposes of this Agreement, no components will be classified as Cambridge
Components-In or Cambridge Components-Out.  In the event the parties agree to
amend this Agreement to provide for "Components-In" or "Components-Out", this
Agreement will also be amended to provide for mutually agreeable license terms
relating thereto.

described in the attached Statement of Work are as follows:

(a)  The warranty period (the "Warranty Period") shall be 30 days following
     Client's acceptance of the Deliverables.  The warranty is subject to Client
     maintaining a support agreement with Cambridge for the duration of the
     Warranty Period.

(b)  Cambridge will make trained software engineers familiar with the
     Deliverables and Client's system available by telephone 24 hours per day, 7
     days per week, during the Warranty  Period, to respond to Client's
     emergency inquiries concerning the operation of the Deliverables, at no
     charge to Client.

(c)  The level of effort required of Cambridge with respect to Errors in the
     Deliverables which have been reported by Client to Cambridge during the
     Warranty Period is as follows:

     (1)  "Critical Errors" are Errors that cause Client's system or one of its
          substantial components to malfunction to a degree that a subscriber
          call is lost and/or the "Essential Information" required to service a
          subscriber properly is unavailable or improperly recorded.  "Essential
          Information" means information required to receive a call, determine
          if it is a "help needed" call, and, if so, to properly assist the
          subscriber in his/her emergency.  If a 

                                      18
<PAGE>
 
          Critical Error occurs, Cambridge will immediately dispatch personnel
          familiar with the Deliverables and Client's system to Client's
          facilities to correct such Critical Error, and will work without
          interruption, using all necessary resources, until such Critical Error
          is corrected.

     (2)  "Severe Errors" are Errors that cause Client's system or one of its
          substantial components to abend, but do not cause the loss of a call
          or prevent Essential Information from reaching a call monitor, or that
          create a significant increase in call response time.  If a Severe
          Error causes more than one call monitor to abend, then it will be
          upgraded to a Critical Error.  If a Severe Error occurs, Cambridge
          will dispatch personnel familiar with the Deliverables and Client's
          system to Client's facilities on the next business day to correct such
          Severe Error, and will work during normal business hours, using
          reasonable resources, until such Severe Error is corrected.

     (3)  "Moderate Errors" are Errors that do not result in a system abend, but
          do create an invalid representation of non-essential information.
          Moderate Errors include report errors.  Cambridge will use reasonable
          efforts to correct Moderate Errors as soon as practicable.

     (4)  "Minor Errors" are Errors not related to the functionality of the
          Deliverables, or which are cosmetic.  Cambridge will use reasonable
          efforts to correct Minor Errors within a commercially reasonable time
          frame.

Date



Dear

This will confirm on behalf of the Board and the Company, that in the event that
within twelve (12) months following a Change of Control, as defined in the
Company's 1991 Stock Option Plan, a copy of the definition being attached
hereto, your employment is terminated without cause or you terminate your
employment in the event your then responsibilities or conditions of employment,
including base salary and principal location at which services are performed,
are significantly changed, reduced or adversely effected, the Company will pay
you, in full satisfaction of any and all claims which you may have against the
Company, an amount equal to one year's base annual salary then being paid to
you.  Termination of employment by the Company shall be deemed to be without
cause unless the termination results from conduct involving moral turpitude or a
willful failure to continue to perform your pre-Change of Control duties,
subject to the direction of post-Change of Control management.

This undertaking should not be construed by you as an employment contract but
does constitute one of the conditions of your ongoing employment relationship
with the Company.

If the foregoing is satisfactory, please indicate your consent below.

Sincerely



Ronald Feinstein
President/CEO

     (c.) Change in Control.  Notwithstanding any other provision of the Plan 
          -----------------   
     and except as otherwise provided in the relevant option agreement, in the
     event of a "Change in Control of the Company" (as defined below), the
     exercise dates of all options then outstanding shall be accelerated in full
     and any restrictions on exercising outstanding options issued pursuant to
     the Plan prior to any given date shall terminate. For purposes of the Plan,
     a "Change in Control of the Company" shall occur or be deemed to have
     occurred only if (i) any "person", as such term is used in Section 13 (d)
     and 14 (d) of the Exchange Act (other than the Company, any trustee or
     other fiduciary holding securities under an employee benefit plan of the
     Company, or any corporation owned directly or indirectly by the
     stockholders of the Company in substantially the same proportion as their
     ownership of stock of the Company), is or becomes the "beneficial owner"
     (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
     of securities of the Company representing 30% or more of the combined
     voting power of the Company's then outstanding securities; (ii) during any
     period of two consecutive years ending during the term of the Plan (not
     including any period prior to the adoption of the Plan), individuals who at
     the beginning of such period constitute the Board of Directors of the
     Company, and any new director (other than a director designated by a person
     who has entered into an agreement with the Company to effect any
     transaction described in clause (i), (iii) or (iv) of this Section 12 (c))
     whose election by the Board of Directors or nomination for election by the
     Company's stockholders was approved by a vote of at least two-third of the
     directors then still in office who were either directors at the beginning
     of the period or whose election or whose nomination for election was
     previously so approved (collectively, the "Disinterested Directors"), cease
     for any reason to constitute a majority of the Board of Directors; (iii)
     the stockholders of the Company approve a merger or consolidation of the
     Company with any other corporation, other than (A) a merger or
     consolidation which would result in the voting securities of the Company
     outstanding immediately prior thereto continuing to represent (either by
     remaining outstanding or by being converted into voting securities of the
     surviving entity) more than 50% of the combined voting power of the voting
     securities of the Company or such surviving entity outstanding immediately
     after such merger or consolidation of (B) a merger or consolidation
     effected to implement a re-capitalization of the Company (or similar
     transaction) in which no "person" (as hereinafter defined) acquires more
     than 30% of the combined voting power of the Company's then outstanding
     securities or (C) a merger or consolidation which has been approved by a
     majority of the Disinterested Directors; or (iv) the stockholders of the
     Company approved a plan of complete liquidation of the Company or an
     agreement for the sale or disposition by the Company of all or
     substantially all of the Company's assets which, in either case, has not
     previously been approved by a majority of the Disinterested Directors.
     Notwithstanding the foregoing, the Board of Directors of the Company may,
     in its sole discretion, by a resolution adopted by two-thirds of the
     Disinterested Directors prior to the occurrence of any of the events
     otherwise constituting a Change in Control of the Company, declare that
     such event will not constitute a Change in Control of the Company for the
     purposes of the Plan. If such resolution is adopted, such event shall not
     constitute a Change of Control of the Company for any purpose of the Plan.
