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

This Quarterly Report on Form 10-Q contains forward-looking statements.  For
this purpose, any statements contained herein that are not statements of
historical fact may be deemed to be forward-looking statements.  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 important factors that could cause the Company's actual
results to differ materially from those indicated by such forward-looking
statements.  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

Total revenues for the quarter ended September 30, 1996 were $12.8 million, an
increase of 12% compared with total revenues of $11.4 million for the quarter
ended September 30, 1995.  For the nine months ended September 30, 1996, total
revenues were $37.0 million, up 15% as compared to revenues of $32.2 million
during the same period in 1995.

Service revenues grew to $6.4 million for the third quarter of 1996 from $5.0
million for the third quarter of 1995 and comprised 50% of total revenues for
the quarter.  For the nine months ended September 30, 1996,  there was a 30%
increase in service revenues to $17.6 million from $13.5 million during the
first nine months of 1995.  Service revenues comprised 48% of the Company's
year-to-date revenues, up from 42% during the same period in 1995. As of
September 30, 1996, the Company served 148,000 subscribers from its two
monitoring centers, including 3,000 subscribers from its July, 1996 acquisition
of CareTel, Inc. as compared to 113,000 subscribers at September 30, 1995. 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 service provided by Lifeline
Central(TM).  The Company believes that the high quality of its services will be
a factor in meeting this challenge.

Product sales were $6.1 million for the three months ended September 30, 1996
and 1995.  For the nine months ended September 30, 1996, product sales increased
5% to $18.5 million from $17.7 during the same period in the prior year.  The
Company continues with its transition to a service-oriented business while
maintaining product sales.  Therefore, the Company's ability to sustain the
current level of product sales in the long run depends on its ability to expand
the market for its personal response services.  The Company believes that its
recent new products and additional new products will be a factor in meeting this
challenge.

Finance and rental income, representing revenue earned from the Company's
portfolio of sales-type leases, remained consistent for the third quarter of
1996 as compared to the same period in 1995.  For the nine months ended
September 30, 1996, finance and rental income decreased $184,000, to $859,000,
from $1,043,000 for the nine months ended September 30, 1995.  In January, 1996
the Company introduced an internally managed 

                                      -7-
<PAGE>
 
and funded leasing program to replace its arrangement with a third-party leasing
agent. This third-party arrangement had been in place since January, 1994, prior
to which the Company had offered its own leasing program. The effect of the 
year-to-date decline in finance income from leases generated by the Company
prior to 1994 was offset in part by finance income earned on leases generated by
the Company during 1996 under the more recent internal leasing program. The
Company believes its customers will continue to take advantage of its new
internal leasing program thereby increasing finance income in future years.

As a percentage of service revenues, cost of services was 43% for the quarter
ended September 30, 1996, as compared to 40% for the same period last year. For
the nine months ended September 30, 1996, cost of services was 44%, as compared
to 39% for the nine months ended September 30, 1995. As the Company grows its
subscriber base and develops its monitoring capabilities, it continues to invest
in personnel and systems supporting its service infrastructure. These
investments have contributed to the increase in service costs and are expected
to continue for the remainder of the year. Therefore, as a percentage of service
revenues, the Company believes that cost of services will remain at
approximately this level through 1996.

Cost of sales was 32% of product sales for the three months ended September 30,
1996, compared with 35% for the same period a year ago. For the nine months
ended September 30, 1996, cost of sales represented 33% of product sales,
compared with 37% during the prior year. The significant improvement is largely
attributable to manufacturing process improvements and the application of new
technology which reduced product costs. The Company expects to maintain cost of
sales as a percentage of product sales at approximately the same level for the
remainder of the year.

Selling, general, and administrative expenses declined to 46% of total revenues
during the three months ended September 30, 1996 from 48% for the three months
ended September 30, 1995. For the nine months ended September 30, 1996, selling,
general, and administrative expenses were 47% of total revenues as compared to
49% for the similar nine month period in 1995. The Company continues to leverage
its administrative infrastructure over a larger revenue base and expects
selling, general, and administrative expenses to remain at approximately the
same level for the remainder of the year.

Research and development expenses were 3% of total revenues for the third
quarter ended September 30, 1996 as compared to 4% for the same period in 1995.
For the nine months ended September 30, 1996 and 1995 research and development
expenses remained constant as a percentage of total revenues at 4%. Research and
development efforts are focused on ongoing product improvements and
developments. The Company expects to maintain these expenses at approximately a
consistent percentage of total revenues.

The Company's effective tax rate was 41% for the three and nine months ended
September 30, 1996, versus 42% for the comparable periods in 1995.

LIQUIDITY AND CAPITAL RESOURCES

During the nine months ended September 30, 1996, cash and cash equivalents
decreased $.2 million to $3.3 million at September 30, 1996 from $3.5 million at
December 31, 1995.   The net decrease in cash resulted from investments in
property and equipment, the purchase of all of the outstanding stock of CareTel
Inc. in July, 1996, and the purchase of 103,000 shares of the Company's common
stock. The Company's positive cash flows from profitable operations along with a
significant increase in accounts payable and accrued expenses, resulting from
the timing of expenditures related to market development and referral programs,
helped to defray the effects of the large expenditures during 1996.

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. for approximately $1,000,000 in cash.  CareTel provides personal
emergency response service under the trade name ProtectAlert and operates a
response center in Toronto, Ontario, Canada.  Approximately $55,000 of the
purchase price was paid in June, 1996, and the remainder paid for in July, 1996
at the time of the closing.  The acquisition was accounted for as a purchase
transaction, and as a result, the Company recorded goodwill of approximately
$1,000,000 which is being amortized over an estimated life of seven years.  The
results of the acquired business have been included in the Company's
consolidated financial statements from the date of acquisition.  The Company
does not expect this acquisition to have a material impact on its 1996 financial
position or results of operations.

During 1995, the Company adopted a revised investment strategy for its cash and
temporary investments.  The implementation of this policy continued during the
first nine months of 1996 as the Company lengthened the maturity structure of
its portfolio and continued to increase its investment portfolio with net
purchases of $1.6 million in marketable securities.

In November, 1995 the Company secured a $4.0 million line of credit effective in
January, 1996.  The 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. There have been no borrowings under this line of credit which
expires November 29, 1996.

In October, 1993, the Company's Board of Directors approved the repurchase of up
to 300,000 shares of the Company's stock from time to time in the open market
for general corporate purposes, including shares for use in connection with
employee stock option plans and stock purchase plans.  The Company has purchased
all of the approved 300,000 shares as of September 30, 1996, including 103,000
shares of treasury stock purchased for $1.3 million during the first nine months
of 1996.

Given the Company's current cash, marketable securities, and revenue levels,
funding requirements for operations and in support of future growth are expected
to be met primarily from existing cash and investment balances and funds
generated from 

                                      -9-
<PAGE>
 
operations.  The Company currently believes that cash provided from these
sources and its available financing will be sufficient to meet its operating and
investing requirements, including funding its internally-managed lease financing
program, and any foreseeable acquisitions through 1996.

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 Quarterly Report on Form 10-Q and presented elsewhere by management from
time to time.

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

The Company's growth is dependent on its ability to increase the number of
subscribers served by its monitoring centers.  In 1995, service revenue was
$18.6 million, accounting for approximately 43% of the Company's total revenues.
For the third quarter of 1996, service revenue was $6.4 million, comprising 50%
of total revenues for the quarter.  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,
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 believes that its future success will also depend in large part upon
its ability to attract and retain key personnel, and there can be no assurance
that the Company will be successful in attracting and retaining such personnel.

          ----------------------                                                
pursuant to this Agreement shall terminate upon the occurrence of any of the
following:

          4.1  Expiration of the Employment Period in accordance with Section 1,
unless extended by the mutual agreement of the parties hereto;

          4.2  At the election of the Company, for cause, immediately upon
written notice by the Company to the Employee. For the purposes of this Section
4.2, cause for termination shall mean (a) willful misconduct or gross negligence
by the Employee or willful failure to perform his responsibilities in the best
interest of the Company (provided, that except

                                       2
<PAGE>
 
in the case of criminal behavior the Employee shall be given at least one
written notice specifying the nature of his misconduct); or (b) the breach by
the Employee of Sections 6, 7 or 16 of this Agreement, which breach continues
for 30 days subsequent to written notice from the Company to the Employee of the
breach (unless such breach is not susceptible to cure, in which case termination
shall be deemed to be immediate).

          4.3  Upon the death or disability of the Employee. As used in this
Agreement, the term "disability" shall mean the inability of the Employee, due
to a physical or mental disability, for a period of 90 days, whether or not
consecutive, during any 360-day period to perform the services contemplated
under this Agreement. A determination of disability shall be made by a physician
satisfactory to both the Employee and the Company; provided that if the Employee
                                                   -------- ----   
and the Company do not agree on a physician, the Employee and the Company shall
each select a physician and these two together shall select a third physician,
whose determination as to disability shall be binding on all parties;

          4.4  At the election of the Employee, upon not less than two months
prior written notice of termination in which event the Company may waive such
notice, in whole or in part, upon payment to the Employee of salary, benefits
and bonuses otherwise payable in respect of such two month period; or

          4.5  At the election of the Company, upon written notice of
termination.

     5.   Effect of Termination.
          --------------------- 

          5.1  Termination for Cause or Voluntary Termination.  In the event the
               ----------------------------------------------                   
Employee's employment is terminated for cause pursuant to Section 4.2, or at the
election of the Employee pursuant to Section 4.4, the Company shall pay to the
Employee the compensation and benefits otherwise payable to him under Section 3
through the last day of his actual employment by the Company.

          5.2  Termination Without Cause.  In the event the Employee's 
               -------------------------       
employment is terminated at the election of the Company pursuant to Section 4.5,
and in consideration of the post-termination non-compete and non-solicitation
agreement set forth in Section 6, the Company shall pay to the Employee (i) a
lump-sum amount at the time of termination equal to the base salary payable to
him under Section 3.1, through December 31, 1999, plus (ii) an amount equal to
the excess, if any, of (A) Cdn $300,000 times a fraction, the numerator of which
is the number of calendar days from the date hereof until the date of
termination and the denominator of which is the number of calendar days from the
date hereof until December 31, 1999, over (B) the amount of bonus payments paid
to the Employee during the Employment Period pursuant to the bonus programs set
forth on Schedule A attached hereto (provided that if there is no excess, no
adjustment shall be made). The payments contemplated in this Section 5.2 include
all entitlement to either notice of termination or pay in lieu of notice and
severance pay under the Employment Standards Act of Ontario. In the event that
the minimum statutory requirements as at the date of termination provide a
greater benefit than provided in this

                                       3
<PAGE>
 
Agreement, such statutory requirements will replace the payments contemplated
under this Agreement.

          5.3  Termination for Death or Disability.  If the Employment Period is
               -----------------------------------                              
terminated by death or because of disability pursuant to Section 4.3, the
Company shall pay to the estate of the Employee or to the Employee, as the case
may be, the compensation which would otherwise be payable to the Employee
through the date of his termination of employment because of death or
disability. In addition, in the event of the Employee's death or disability
during the Employment Period, the Company shall pay to the Employee or his
estate within two weeks after his death or termination due to disability, a lump
sum payment equal to (X) the lesser of (A) one year's base salary under Section
3.1; and (B) the base salary under Section 3.1 which would have been payable to
the Employee for the period from the date of death or termination due to
disability through December 31, 1999, were the Employee not deceased or so
disabled, plus (Y) an amount equal to the excess, if any, of (A) Cdn $300,000
times a fraction, the numerator of which is the number of calendar days from the
date hereof until the date of the Employee's death or termination due to
disability and the denominator of which is the number of calendar days from the
date hereof until December 31, 1999, over (B) the amount of bonus payments paid
to the Employee pursuant to the bonus programs set forth on Schedule A attached
hereto.

          5.4  Survival.  The provisions of Sections 6, 7 and 16 shall survive
               --------         
 the termination of this Agreement.

     6.   Non-Compete.
          ----------- 

          (a)  The Employee recognizes that his willingness to enter into the
restrictive covenants contained in this Section 6 was a critical condition
precedent to the willingness of the Company to acquire the capital stock of
CareTel and of the Company to enter into and perform under this Agreement. The
Employee also acknowledges that the restrictions contained in this Section 6
will not materially or unreasonably interfere with the Employee's ability to
earn a living.

          (b)  During the Employment Period and for a period of 5 years after
the termination or expiration thereof, the Employee will not directly or
indirectly, within Canada or the United States of America;

               (i)   as an individual proprietor, partner, stockholder, officer,
employee, director, joint venturer, investor, lender, or in any other capacity
whatsoever (other than as the holder of not more than one percent (1%) of the
total outstanding stock of a publicly held company), engage in the business of
developing, producing, marketing or selling products or services of the kind or
type produced, marketed or sold by Lifeline Systems, Inc. on the date 

                                       4
<PAGE>
 
hereof or any other business engaged in by the Company after the date hereof in
which the Employee has non-trivial involvement; or

               (ii)  recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company or to accept any employment
or consulting relationship with the Employee or any third party; or

               (iii) solicit in a manner competitive with the business of
Lifeline Systems, Inc., divert or take away, or attempt to divert or to take
away, the business or patronage of any of the clients, customers or accounts, or
prospective clients, customers or accounts, of the Company which were contacted,
solicited or served by employees of the Company while the Employee was employed
by the Company.

          (c)  If any restriction set forth in this Section 6 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable. The parties intend that the restrictions in this Section 6 shall be
deemed to be a series of separate covenants, one for each and every county of
each and every state of the United States of America and each and every
political subdivision of Canada.

          (d)  The restrictions contained in this Section 6 are necessary for
the protection of the business and goodwill of the Company and are considered by
the Employee to be reasonable for such purpose. The Employee agrees that any
breach of this Section 6 will cause the Company substantial and irrevocable
damage and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Company shall have the right to seek
specific performance and injunctive relief.

          (e)  For purposes of this Section 6, the "Company" refers to the
Company, Lifeline and any of their respective affiliates.

          (f)  The Employee acknowledges that he is party to non-competition and
non-solicitation covenants in Sections 8.02 and 8.03 of that certain Stock
Purchase Agreement among CareTel, the Company and the former stockholders of the
Company dated as of the date hereof (the "Stock Purchase Agreement"). The
Employee agrees that nothing in this Agreement shall be deemed to affect any
provision of the Stock Purchase Agreement, including without limitation such 
non-competition and non-solicitation covenants. In the event that the 
non-competition and non-solicitation covenants in this Agreement would expire
before those in the Stock Purchase Agreement, or vice versa, the Employee
acknowledges his intention that he shall, following the first to expire of such
covenants, continue to be bound until the other of such covenants expire by
their terms.

                                  SCHEDULE A

                                BONUS PAYMENTS

I.   ANNUAL PERFORMANCE BONUS

          The Employee shall be entitled to an annual bonus payment, half of
     which will be based upon the level of pre-tax profit actually attained by
     the Company in such year in relation to target and budgeted pre-tax profit,
     and the other half of which will be based upon the level of revenue
     actually attained by the Company in such year in relation to target and
     budgeted revenue. Annually, prior to the beginning of each of calendar
     years 1997, 1998 and 1999, the Employee and the Company will set financial
     targets to be attained for such calendar year (the "Financial Targets").
     These targets will begin with the joint development of pro forma 1996
     annualized revenue and pre-tax profit baseline numbers. Baseline 1996 pro
     forma numbers will reflect the annualized profit and loss statement
     combining the Company and CareTel. The profit and loss statement will
     reflect only those revenues, costs and goodwill that are directly
     associated with the Company and CareTel. They will not include any
     allocation of management fees from Lifeline Systems, Inc. The Employee and
     the Company will endeavor to develop a mutually agreeable profit and loss
     statement which reflects a true pro forma representation of the 1996 annual
     results.

          The Employee's annual bonus is to be calculated as follows. All bonus
     amounts are expressed as a percentage of the Employee's annualized base
     salary for the applicable calendar year, and shall be paid by the Company
     promptly following the availability of audited financial results for such
     year.

     Pre-Tax Profit
     --------------

          The Pre-Tax Profit portion of the Employee's bonus payment shall be
     calculated for each of calendar years 1997, 1998 and 1999 as follows:

</TABLE>

                                       10
<PAGE>
 
Payments will be linearly determined between each set of points. There will be
no cap on bonus payments; however, in the event of unusual non-operational
profit windfalls to the Company, the CEO of Lifeline Systems, Inc. may, in his
sole discretion, adjust the profit calculation for purposes hereof and consider
the appropriateness of a one-time bonus payment associated with such unusual
items, or may exclude such items from the bonus calculation. Coopers & Lybrand
will be responsible for arbitrating any disputes over whether an item is
unusual. Pre-tax profit in excess of the applicable annual target will accrue
additional bonus payout points at a rate of 1% of the Employee's annual base
salary for every $_______/*/ of pre-tax profit in excess of the applicable
earnings.
 
Revenue

The revenue portion of the Employee's bonus payment shall be calculated for each
of calendar years 1997, 1998 and 1999 as follows:

Payments will be linearly determined between each set of points. There will be
no cap on bonus payments; however, in the event of unusual non-operational
revenue windfalls to the Company, the CEO of Lifeline Systems, Inc. may, in his
sole discretion, adjust the revenue calculation for purposes hereof and consider
the appropriateness of a one-time bonus payment associated with such unusual
items, or may exclude such items from the bonus calculation. Coopers & Lybrand
will be responsible for arbitrating any disputes over whether an item is
unusual. Revenue in excess of the applicable annual target will accrue
additional bonus payout points at a rate of 1% of the Employee's annual base
salary for every $________/*/*/ of revenue in excess of the applicable annual
target.

II.  LONG-TERM PERFORMANCE BONUS

     Prior to January 1, 1997, the Company and the Employee shall develop a
three-year strategic plan with revenue and pre-tax profit growth targets to be
attained by the Company by December 31, 1999 from the baseline revenue and pre-
tax profit pro forma numbers developed pursuant to the first paragraph of this
Schedule A. If the Employee remains employed by the Company through December 31,
1999, then on or before March 31, 2000, the Company shall pay the Employee a
Long-Term Performance Bonus calculated as follows:

Payments will be linearly determined between each set of point , Pre-tax profit
attainment in excess of target will result in additional bonus payout dollars at
a rate of $_______/**/*/ for each dollar in pre-tax profit in excess of target.
Revenue attainment in excess of target will result in additional bonus payout
dollars at a rate of $________*** for each dollar in revenue in excess of
target. There will be no cap on the bonus payment; however, in the event of an
unusual non-operational profit or revenue windfalls to the Company, the CEO of
Lifeline Systems, Inc. may, in his sole discretion, adjust the profit and
revenue calculations and consider the appropriateness of a bonus payment
associated with such unusual items, or may exclude such items from the bonus
calculation. Coopers & Lybrand will be responsible for arbitrating any disputes
over whether an item is unusual.

In the event the Employee is terminated by the Company after December 31, 1998,
but before December 31, 1999, he shall be entitled to a pro rata portion of the
Long-Term Performance Bonus calculated by multiplying (A) the Estimated Bonus
Payment (as defined below) times a fraction, the numerator of which is the
number of calendar days from the date hereof until the date of termination and
the denominator of which is the number of calendar days from the date hereof
until December 31, 1999. The "Estimated Bonus Payment" means the Company's
reasonable estimate of the bonus that would have been payable under this Section
II if the Employee had been employed until December 31, 1999 . Such estimate
will be calculated by averaging the revenue and pre-tax profit growth over each
of 1997 and 1998 and the projected revenue and pre-tax profit growth in 1999.
Coopers & Lybrand will be responsible for arbitrating any disputes over the
interpretation of this provision and/or the calculation provided for herein.

EXAMPLE
- -------

The following example illustrates the calculation of the bonus payment. In the
example, the Company pays additional bonus payout dollars of $12,500 for each
$50,000 dollars in pre-tax profit in excess of target and additional bonus
payout dollars of $10,000 for each $100,000 in revenue in excess of target. Pre-
tax profit will be calculated before deducting bonus earnings.

III. MINIMUM BONUS

     If the Employee remains employed by the Company through December 31, 1999,
the Company shall, no later than January 15, 2000, pay the Employee the
difference, if any, by which Cdn $300,000 exceeds the aggregate bonus payments
made by the Company to the Employee pursuant to Sections I and II above.

IV.  CREDIT FOR UNITED STATES OPPORTUNITY

     For purposes of calculating the bonus payments under Sections I and II
above, the Employee will be given credit for revenue and pre-tax profit from any
transactions from time to time arising from the National Meals on Wheels
Foundation initiative which the Employee has described to the Buyer prior to the
date hereof; provided, however, that the Employee will only be given credit for
such amounts if such relationship is consummated on or prior to June 30, 1997.
The pre-tax profit calculation will be based on cost allocations made by the
Buyer in its reasonable judgment.

not be available unless the terms and conditions of Rule 144 are complied with.

                      (c) A legend substantially in the following form will be

                      "The shares represented by this certificate have

                      Securities Act of 1933, as amended, and may not
                      be sold, transferred or otherwise disposed of in
                      the absence of an effective registration
                      statement under such Act or an opinion of
                      counsel satisfactory to the corporation (which
                      shall include Peabody & Arnold if counsel to the
                      corporation does not issue such opinion
                      following written request) to the effect that
                      such registration is not required. No such
                      opinion shall be required if the shares
                      represented by this certificate are eligible for
                      resale under Rule 144(k) under the Securities
                      Act, and in the event that the shares are
                      eligible for resale under said Rule 144(k), this
                      legend shall be removed following the request of
                      the holder."

                      (d) He has good and marketable title to the Shares, free
and clear of any and all covenants, conditions, restrictions, voting trust
arrangements, liens, charges, encumbrances, options and adverse claims or rights
whatsoever.

                      (e) He has the full right, power and authority to enter
into this Agreement and to transfer, convey and sell to the Buyer at the Closing
the Shares and, upon consummation of the purchase contemplated hereby, the Buyer
will acquire from the Stockholder good and marketable title to the Shares, free
and clear of all covenants, conditions, restrictions, voting trust arrangements,
liens, charges, encumbrances, options and adverse claims or rights whatsoever.

                      (f) He is not a party to, subject to or bound by any
agreement or other restriction or any judgment, order, writ, prohibition,
injunction or decree of any court or other governmental body which would prevent
the execution or

                                      -2-
<PAGE>
 
delivery of this Agreement by the Stockholder or the transfer, conveyance and
sale of the Shares.

                      (g) No broker or finder has acted for the Stockholder in
connection with this Agreement or the transactions contemplated hereby, and no
broker or finder is entitled to any brokerage or finder's fee or other
commissions in respect of such transactions based upon agreements, arrangements
or understandings made by or on behalf of the Stockholder or the Company.

          2.   Registration Rights.  Lifeline Systems, Inc. hereby agrees that,
               -------------------                                             
following the request of the Stockholder to register the Lifeline Stock for
resale under the Securities Act (provided that the Stockholder is not then
prohibited from reselling the Lifeline Stock), it will file a Form S-3
Registration Statement with the Securities and Exchange Commission covering the
Lifeline Stock (provided it is then eligible to do so).  Notwithstanding the
foregoing, (i) Lifeline Systems, Inc. shall not be required to so file a
registration statement pursuant hereto to the extent that the Stockholder would
then be permitted to sell the Lifeline Stock under Rule 144 under the Securities
Act; and (ii) Lifeline shall have the right to postpone the filing of any such
registration statement for a period not in excess of six months if at the time
of the requested filing thereof Lifeline Systems, Inc. is engaged or has fixed
plans to engage in a registered public offering or is engaged in any other
activity which, in the good faith determination of Lifeline Systems, Inc.'s
board of directors, would be adversely affected by the requested registration to
the material detriment of Lifeline Systems, Inc.  The Stockholder agrees to
cooperate with Lifeline Systems, Inc. in the registration of the Lifeline Stock
pursuant to this Section.

          Lifeline Systems, Inc. agrees that in the event the Stockholder sells
the Lifeline Stock pursuant to Rule 144 under the Securities Act, it will not in
any manner restrict its counsel from issuing any legal opinion as may be
required by the Company's transfer agent in order to remove the transfer
restrictions from the Lifeline Stock.  Lifeline Systems, Inc. agrees that
damages are an inadequate remedy for any breach of this provision and that the
Stockholder shall, whether or not he is pursuing any potential remedies at law,
be entitled to equitable relief in the form of preliminary and permanent
injunctions without bond or other security upon any actual or threatened breach
of this provision.

          Lifeline Systems, Inc. further agrees that, at the request of the
Stockholder, it will repurchase the Lifeline Stock in the event that the
Lifeline Stock is not registered under the Securities Act within 60 days after
written notice by the Stockholder to Lifeline Systems, Inc., requesting such
notice (provided that at the time of such request the Stockholder is not
prohibited from reselling the Lifeline Stock.  The purchase price to be paid by
Lifeline Systems, Inc. will be the last sale price of Lifeline Systems, Inc.
common stock on the date on which such notice is given.

          At such time as the Lifeline Stock becomes available for resale
pursuant to Rule 144(k) under the Securities Act, the Company shall cause the
legend to be removed without the requirement of opinion of counsel.

          3.   Governing Law.  This Agreement shall be governed by and construed
               -------------

                             Preliminary Statement
                             ---------------------

     1.  Each of the Stockholders owns the number of the issued and outstanding

conditions of this Agreement.

     NOW, THEREFORE, in consideration of the mutual promises hereinafter set

     1.  Purchase and Sale of the Shares.
         ------------------------------- 

         1.01  Purchase of the Shares from the Stockholders.  Subject to and
               --------------------------------------------
upon the terms and conditions of this Agreement, at the closing of the

                             ---------

               ------------------                                              
Closing, at the Buyer's request and without further consideration, each of the
Stockholders shall promptly execute and deliver such instruments of sale,
transfer, 
<PAGE>
 
conveyance, assignment and confirmation, and take all such other
action as the Buyer may reasonably request, more effectively to transfer, convey
and assign to the Buyer, and to confirm the Buyer's title to, all of the Shares
owned by such Stockholder, to assist the Buyer in exercising all rights with
respect to the Company and to carry out the purpose and intent of this
Agreement.

         1.03  Purchase Price for the Shares.
               ----------------------------- 

               (a) The purchase price to be paid by the Buyer for the Shares
shall be an amount (the "Cash Purchase Price") equal to One Million Three
Hundred and Eighty-Five Thousand Canadian Dollars (Cdn $1,385,000), less
$600,5421.18, representing the amount of all outstanding shareholders'
debentures, bank indebtedness and all other indebtedness of the Company for
borrowed money, including all prepayment penalties and accrued interest, if any,
payable as a result of the payment in full of such debentures, bank or other
indebtedness at the Closing (collectively, but specifically excluding the
liability (approximately $40,000) in respect of the marketing services fee
payable to Extendicare (Canada) Inc., the "Indebtedness"). The Cash Purchase
Price shall be payable in the manner described in paragraphs (b) and (c) of this
Subsection 1.03.

               (b) At the Closing, the Buyer shall deliver to Silver, Brown,
Sosnovitch, in trust for the Stockholders, an amount equal to the Cash Purchase
Price, less $9,083.51, representing twenty-five percent (25%) of the face amount
of the Closing Receivables (as defined below), in cash, by cashier's or
certified check, or by wire transfer of immediately available funds to an
account designated by the Stockholders' Representative, for distribution to the
Stockholders by Silver, Brown, Sosnovitch in the amounts set forth opposite each
such Stockholder's name on Schedule 1 attached hereto. The amount of cash paid
                           ----------                                          
by the Buyer at the Closing shall be further reduced by the Cdn $75,000 deposit
paid by the Buyer, which shall be applied against the Cash Purchase Price.  For
the purposes hereof, "Closing Receivables" shall mean the accounts receivable of
the Company as of the Closing Date, as certified in writing to the Buyer by
Leonard Wechsler, on behalf of the Stockholders.

               (c) Following the Closing, the Stockholders shall be entitled to
additional payments of the Cash Purchase Price solely in accordance with the
provisions of this paragraph. Any collections on account of the Closing
Receivables shall be for the account of the Company until the Company has
collected, on account thereof, an amount equal to seventy-five percent (75%) of
the aggregate amount of the Closing Receivables. Thereafter, any collections on
the Closing Receivables shall be for the account of the Stockholders, and shall
be paid to the Stockholders' Representative for distribution to the Stockholders
by the Stockholders' Representative on or before the 

                                      -2-
<PAGE>
 
15th day of the calendar month following the calendar month in which such amount
is received by the Company.

The Company shall have no obligation to make any efforts to collect any of the
Accounts Receivable.  In the event that any payment received by the Company is
remitted by a customer which is indebted under both a Closing Receivable and an
account receivable arising out of the sale of inventory or services in the
ordinary course of business after the Closing Date (a "New Receivable"), such
payments shall first be applied to the Closing Receivable due from such customer
and the balance remaining after payment in full of all Closing Receivables due
from such customer shall be applied to the New Receivable; provided, however,
that (i) with respect to any Closing Receivable being contested or disputed by
the payor thereof, no portion of the amount in dispute shall be deemed to have
been collected by the Company in respect of the Closing Receivable due from such
customer (unless otherwise directed by such customer) until all amounts owed by
such customer to the Company for New Receivables have been paid or such dispute
has been resolved, whichever occurs first, and (ii) the foregoing priorities
shall not apply to sums received by the Company which are specifically
identified by the customer as being tendered in payment of a New Receivable.

               (d) Any balance (or overdraft) in the Company's bank account as
of June 30, 1996, after reconciliation to the bank statement, shall be for the
benefit of (or the obligation of) the Sellers, and payment shall be made by the
Company to the Stockholders' Representative, or by the Sellers (jointly and
severally) to the Company, as the case may be, within five (5) days of
reconciliation. Any cash generated by the Company after June 30, 1996 shall be
for the benefit of the Company, and shall not be distributed to the Sellers.

         1.04  Stockholders' Representative.
               ---------------------------- 

               (a) In order to efficiently administer (i) the waiver of any
condition to the obligations of the Stockholders to consummate the transactions
contemplated hereby, and (ii) the defense and/or settlement of any claims for
which the Stockholders may be required to indemnify the Buyer or the Company
pursuant to Section 7 hereof, the Stockholders hereby designate Leonard Wechsler
as their representative (the "Stockholders' Representative").

               (b) The Stockholders hereby authorize the Stockholders'
Representative (i) to take all action necessary in connection with the waiver of
any condition to the obligations of the Stockholders to consummate the
transactions contemplated hereby, or the defense and/or settlement of any claims
for which the Stockholders may be required to indemnify the Buyer or the Company
pursuant to 

                                      -3-
<PAGE>
 
Section 7 hereof, (ii) to give and receive all notices required to
be given under the Agreement, and (iii) to take any and all additional action as
is contemplated to be taken by or on behalf of the Stockholders by the terms of
this Agreement.

               (c) In the event that the Stockholders' Representative dies,
becomes unable to perform his responsibilities hereunder or resigns from such
position, Stockholders holding, prior to the Closing, a majority of the Shares
as set forth on Schedule 1 attached hereto shall select another representative
                ----------
to fill such vacancy and such substituted representative shall be deemed to be
the Stockholders' Representative for all purposes of this Agreement.

               (d) All decisions and actions by the Stockholders'
Representative, including, without limitation, any agreement between the
Stockholders' Representative and the Buyer relating to the defense or settlement
of any claims for which the Stockholders may be required to indemnify the Buyer
and/or the Company pursuant to Section 7 hereof, shall be binding upon all of
the Stockholders, and no Stockholder shall have the right to object, dissent,
protest or otherwise contest the same.

               (e) By their execution of this Agreement, the Stockholders agree
that:

     (i)    the Buyer shall be able to rely conclusively on the instructions and
decisions of the Stockholders' Representative as to the settlement of any claims
for indemnification by the Buyer or the Company pursuant to Section 7 hereof or
any other actions required to be taken by the Stockholders' Representative
hereunder, and no party hereunder shall have any cause of action against the
Buyer for any action taken by the Buyer in reliance upon the instructions or
decisions of the Stockholders' Representative;

     (ii)   all actions, decisions and instructions of the Stockholders'
Representative shall be conclusive and binding upon all of the Stockholders and
no Stockholder shall have any cause of action against the Stockholders'
Representative for any action taken, decision made or instruction given by the
Stockholders' Representative under this Agreement, except for fraud or willful
breach of this Agreement by the Stockholders' Representative;

     (iii)  the provisions of this Subsection 1.04 are independent and
severable, are irrevocable and coupled with an interest and shall be enforceable
notwithstanding any rights or remedies that any Stockholder may have in
connection with the transactions contemplated by this Agreement;

                                      -4-
<PAGE>
 
     (iv)   remedies available at law for any breach of the provisions of this
Subsection 1.04 are inadequate; therefore, the Buyer and the Company shall be
entitled to temporary and permanent injunctive relief without the necessity of
proving damages if either the Buyer or the Company brings an action to enforce
the provisions of this Subsection 1.04; and

     (v)    the provisions of this Subsection 1.04 shall be binding upon the
executors, heirs, legal representatives and successors of each Stockholder, and
any references in this Agreement to a Stockholder or the Stockholders shall mean
and include the successors to the Stockholders' rights hereunder, whether
pursuant to testamentary disposition, the laws of descent and distribution or
otherwise.

Representative shall be paid by the Stockholders.

indemnifying 

                                      -23-
<PAGE>
 
Stockholder (in the case of indemnification under Section 7.01(II) above (in
either case, as applicable, the "Indemnifying Party") of the claim and, when
known, the facts constituting the basis for such claim. In the event of any such
claim for indemnification hereunder resulting from or in connection with any
claim or legal proceedings by a third party, the notice shall specify, if known,
the amount or an estimate of the amount of the liability arising therefrom. The
Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent, which shall not be unreasonably withheld or delayed, of the
Indemnifying Party; provided, however, that if suit shall have been instituted
against the Indemnified Party and the Indemnifying Party shall not have taken
control of such suit after notification thereof as provided in Subsection 7.03
of this Agreement, the Indemnified Party shall have the right to settle or
compromise such claim upon giving notice to the Indemnifying Party as provided
in Subsection 7.03.

         7.03  Defense by the Indemnifying Party.  In connection with any claim
               ---------------------------------
which may give rise to indemnity hereunder resulting from or arising out of any
claim or legal proceeding by a person other than the Indemnified Party, the
Indemnifying Party, at his or its sole cost and expense, may, upon written
notice to the Indemnified Party, assume the defense of any such claim or legal
proceeding if the Indemnifying Party acknowledges to the Indemnified Party in
writing his or its obligation to indemnify the Indemnified Party with respect to
all elements of such claim. If the Indemnifying Party assumes the defense of any
such claim or legal proceeding, the Indemnifying Party shall select counsel
reasonably acceptable to the Indemnified Party to conduct the defense of such
claims or legal proceedings and at the sole cost and expense of the Indemnifying
Party shall take all steps necessary in the defense or settlement thereof. The
Indemnifying Party shall not consent to a settlement of, or the entry of any
judgment arising from, any such claim or legal proceedings, without the prior
written consent of the Indemnified Party (which consent shall not be
unreasonably withheld or delayed). The Indemnified Party shall be entitled to
participate in (but not control) the defense of any such action, with its own
counsel and at its own expense. If the Indemnifying Party does not assume the
defense of any such claim or litigation resulting therefrom within 30 days after
the date such claim is made: (a) the Indemnified Party may defend against such
claim or litigation in such manner as it may deem appropriate, including, but
not limited to, settling such claim or litigation, after giving notice of the
same to the Indemnifying Party, on such terms as the Indemnified Party may deem
appropriate, and (b) the Indemnifying Party shall be entitled to participate in
(but not control) the defense of such action, with its counsel and at its own
expense. If the Indemnifying Party thereafter seeks to question the manner in
which the Indemnified Party defended such third party claim or the amount or
nature of any such settlement, the Indemnifying Party shall have the burden to
prove by a preponderance of the evidence that the Indemnified Party did not
defend or settlement such third party claim in a reasonably prudent manner.

                                      -24-
<PAGE>
 
         7.04  Payment of Indemnification Obligation.  Each of the Stockholders
               -------------------------------------
hereby agrees that any claim for indemnification by the Buyer, or the Company
(if the Closing occurs), under this Section 7 or under any other provision of
this Agreement may, at the option of the Buyer or the Company, as the case may
be, be offset against any amount owed to the Stockholders on account of the
collection of the Closing Receivables or pursuant to Section 1.03(d). All
indemnification by any Indemnifying Party hereunder (to the extent not satisfied
in the manner specified in the preceding sentence), and any indemnification by
the Company if the Closing does not occur, shall be effected by payment of cash
or delivery of a cashier's or certified check in the amount of the
indemnification liability.

         7.05  Survival of Representations; Claims for Indemnification.  All
               -------------------------------------------------------

this Agreement, or in any instrument or document furnished in connection with
this Agreement or the transactions contemplated hereby (other than Section 3.01,
3.02, 3.04 and 3.15, which shall survive until the expiration of all applicable
statutes of limitations), shall survive the Closing and any investigation at any
time made by or on behalf of the Indemnified Party for a period of two years
after the Closing Date.  All representations and warranties made by the
Stockholders in Article 2 of this Agreement shall survive until the expiration
of all applicable statute of limitations.

         7.06  Notwithstanding anything contained herein to the contrary, other
than in connection with a breach of Section 1.03(d): (i) no Stockholder shall be
liable hereunder for any amount greater than the gross proceeds received by him,
her or it on account of the sale by such person of shares of stock of the
Company to the Buyer, whether pursuant to this Agreement or any other agreement
with the Company; and (ii) Wechsler shall not be liable for any claim under
Section 7.01(I) until the aggregate Losses arising thereunder exceed $20,000, in
which case Wechsler shall be liable for all such Losses, and not just those
exceeding $20,000.

such Stockholder or any Affiliate thereof to hold in confidence all knowledge
and information of a secret or confidential nature with respect to the business
of the Company and not to disclose, publish or make use of the same without the
consent of the Buyer, except to the extent

                                      -25-
<PAGE>
 
that such information shall have become public knowledge other than by breach of
this Agreement by the Stockholders or their Affiliates. For purpose of this
Agreement, an "Affiliate" of a person means a party which is controlling,
controlled by, or under common control with, such person.

               (b) If (i) the employment of an officer, director or other
employee of a Stockholder or any Affiliate thereof, to whom secret or
confidential knowledge or information concerning the business of the Company has
been disclosed, is terminated and (ii) such individual is subject to an
obligation to maintain such knowledge or information in confidence after such
termination, the Stockholders shall, upon request by the Buyer, take all
reasonable steps at their expense to enforce such confidentiality obligation in
the event of an actual or threatened breach thereof. Any legal counsel retained
by any such Stockholder in connection with any such enforcement or attempted
enforcement shall be selected by such Stockholder, but shall be subject to the
approval of the Buyer, which approval shall not be unreasonably withheld.

               (c) Each Stockholder agrees that the remedy at law for any breach
of this Subsection 8 would be inadequate and that the Buyer shall be entitled to
injunctive relief in addition to any other remedy it may have upon breach of any
provision of this Subsection 8.01.

         8.02  No Solicitation or Hiring of Former Employees.  Except as
               ---------------------------------------------
provided by law, for a period of six years after the Closing Date, no
Stockholder nor any Affiliate (as defined in Section 8.01 above) thereof shall
(a) solicit any person who was an employee of the Company on the date hereof or
the Closing Date to terminate his employment with the Buyer or any Affiliate
thereof or while employed by the Buyer or any Affiliate of the Buyer, to provide
services to such Stockholder or Affiliate thereof, or (b) hire any person who
was an employee of the Company on the date hereof or on the Closing Date and,
within three months before such hiring, was an employee of the Buyer or any
Affiliate thereof.

         8.03  Non-Competition Agreement.
               -------------------------

               (a) For a period of six years after the Closing Date, no
Stockholder nor any Affiliate thereof shall, directly or indirectly, as an
individual proprietor, partner, stockholder, officer, employee, director, joint
venturer, investor, lender, or in any other capacity whatsoever (other than as
the holder of not more than one percent (1%) of the total outstanding stock of a
publicly held company), except as an officer or employee of the Company,
develop, manufacture, market or sell any product or service which competes with
the present business of the Company, Lifeline Systems, Inc. or the Buyer, which
is the business of selling, renting, installing, 

                                      -26-
<PAGE>
 
monitoring and servicing personal and medical emergency response services and
systems, in the United States or Canada or any other country in which the
Company conducted its business during the two years prior to the Closing Date.
It is acknowledged that this covenant is not intended to restrict those
Stockholders who, as of the date hereof, provide consulting services to health
care institutions and/or community service organizations which may also be
provided personal emergency response services in a manner which is incidental to
such institution's or organization's main activities, from continuing to provide
such consulting services.

               (b) The parties hereto agree that the duration and geographic
scope of the non-competition provision set forth in this Subsection 8.03 are
reasonable. In the event that any court of competent jurisdiction determines
that the duration or the geographic scope, or both, are unreasonable and that
such provision is to that extent unenforceable, the parties hereto agree that
the provision shall remain in full force and effect for the greatest time period
and in the greatest area that would not render it unenforceable. The parties
intend that this non-competition provision shall be deemed to be a series of
separate covenants, one for each and every county of each and every state of the
United States of America and each and every political subdivision of each and
every country outside the United States of America where this provision is
intended to be effective. The Stockholders agree that damages are an inadequate
remedy for any breach of this provision and that the Buyer shall, whether or not
it is pursuing any potential remedies at law, be entitled to equitable relief in
the form of preliminary and permanent injunctions without bond or other security
upon any actual or threatened breach of this non-competition provision.

     9.  Brokers; For the Stockholders and the Company.  Each of the
         ---------------------------------------------
Stockholders and the Company represent and warrant that no person, firm or
corporation has acted in the capacity of broker or finder on its behalf to bring
about the negotiation of this Agreement. The Stockholders jointly and severally
agree to indemnify and hold harmless the Buyer against any claims or liabilities
asserted against it by any person acting or claiming to act as a broker or
finder on behalf of the Stockholders or the Company.

     10. Brokers; For the Buyer.  The Buyer agrees to pay all fees, expenses and
         ----------------------
compensation owed to any person, firm or corporation who has acted in the
capacity of broker or finder on its behalf to bring about the negotiation of
this Agreement. The Buyer agrees to indemnify and hold harmless the Stockholders
against any claims or liabilities asserted against it by any person acting or
claiming to act as a broker or finder on behalf of the Buyer.
