                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        
1.   The information furnished has been prepared from the accounts without
     audit. In the opinion of the Company, the accompanying consolidated
     financial statements contain all adjustments necessary, consisting only of
     those of a normal recurring nature, to present fairly its consolidated
     financial position as of September 30, 1998 and the consolidated results of
     its operations and cash flows for the nine months ended September 30, 1998
     and 1997.

     While the Company believes that the disclosures presented are adequate to
     make the information not misleading, these statements should be read in
     conjunction with the consolidated financial statements and the related
     notes included in the Company's Annual Report on Form 10-K, as filed with
     the Securities and Exchange Commission on March 19, 1998 for the year ended
     December 31, 1997.
 
     Certain amounts in the prior year have been reclassified from selling,
     general, and administrative expenses to cost of services to conform to the
     current presentation.

     The results of operations for the three and nine month periods ended
     September 30, 1998 are not necessarily indicative of the results expected
     for the full year.

4.  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 management's 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.

5.  The Company entered into an Agreement and Plan of Merger (the "Merger 
    Agreement"), dated as of October 18, 1998 with Protection One, Inc. and a
    subsidiary of Protection One, Inc. (the "Merger Sub"), pursuant to which,
    subject to the terms and conditions of the Merger Agreement, the Company
    will be merged with and into the Merger Sub. In connection with the merger,
    each share of the Company's common stock will be converted into the right to
    receive $14.50 plus a certain number of shares of the common stock of a
    newly formed holding company for Protection One, based on the average
    closing price of Protection One's common stock prior to

    the consummation of the transaction and adjusted for a variable exchange
    rate. The number of shares of Protection One holding company common stock to
    be received by the Company's stockholders will be based on the average
    closing price of Protection One common stock for the ten days ending three
    days prior to the company's shareholder meeting to be held in connection
    with the transaction (the "Average Closing Price"). The number of shares of
    holding company common stock to be received by the Company's shareholders
    per share of the Company's common stock will be as follows:

 

    (A)  1.7857 if the Average Closing Price is less than $7.00;  
    (B)  the quotient obtained by dividing (x) $12.50 by (y) the Average Closing
         Price, if the Average Closing Price is equal to or greater than $7.00 
         but less than $8.19; 
    (C)  1.5263 if the Average Closing Price is equal to or greater than $8.19
         but less than $9.50;
    (D)  the quotient obtained by dividing (x) $14.50 by (y) the Average Closing
         Price, if the Average Closing Price is equal to or greater than $9.50
         but less than $11.00; and
    (E)  1.3182 if the Average Closing Price is equal to or greater than $11.00.

    Based on the closing stock price of Protection One common stock on October
    16, 1998, each share of the Company's common stock would have been converted
    to the right to receive shares of holding company common stock worth
    approximately $15.24. The acquisition will be accounted for as a purchase
    and is intended to qualify as a tax-free reorganization to the extent of the
    holding company common stock received in the transaction. The merger is
    conditioned upon, among other things, approval by shareholders of the
    Company and Protection One, and expiration or termination of the waiting
    period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. The
    Merger Agreement has been approved by the boards of directors of Protection
    One and the Company, and the merger is expected to be completed in early
    1999.

ITEM 2.   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

Total revenues for the quarter ended September 30, 1998 were $16.3 million, a
15% increase over total revenues of $14.2 million for the quarter ended
September 30, 1997.  For the nine months ended September 30, 1998, total
revenues were $47.3 million, up 13% over revenues of $42.0 million during the
same period in 1997.

Service revenues, which grew 21% to $10.0 million for the three months ended
September 30, 1998 and 22% to $28.5 million for the nine months ended September
30, 1998, represented 60% of the Company's year to date total revenues. This
increase reflects the Company's strategy of growing the service business.  The
Company is now monitoring approximately 223,000 subscribers as of September 30,
1998, 21% more than the nearly 184,000 subscribers monitored at September 30,
1997.  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, convert community hospital programs to service provided by the Company
and increase its focus on referral development and innovative partner
relationships in new channels of distribution.  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
enabling the Company to meet this challenge.

Net product revenues for the second quarter of 1998 increased 5% to $5.9 million
as compared to $5.6 million for the second quarter of 1997.  For the nine months
ended September 30, 1998, net product revenues remained consistent with the nine
months ended September 30, 1997 at $17.8 million.  For the first nine months of
1998, the Company has been able to maintain its product sales while continuing
with its strategy of providing the hardware as part of the monthly service fee
to support the transition to a service oriented business.  However, the Company
expects declining product sales in future periods as it continues packaging
products and services into a single service offering.

Finance and rental income, representing revenue earned from the Company's
portfolio of sales-type leases, increased 22% for the second quarter of 1998 to
$347,000, from $285,000 for the same period last year.  For the nine months
ended September 30, 1998, finance and rental income rose 19% to $1.0 million as
compared to $854,000 for the nine months ended September 30, 1997.  The increase

                                      -9-
<PAGE>
 
is a result of the continued growth of the Company's internally managed and
funded leasing program.  The Company believes that the retention of new leases
in its own portfolio will result in an increase in finance income for the
remainder of 1998.

Cost of services, as a percentage of service revenues, was 56% for the three
months ended September 30, 1998 as compared to 54% for the three months ended
September 30, 1997.  For the nine months ended September 30, 1998, cost of
services was 57% of year to date service revenues, as compared to 54% for the
same period last year.  Cost of services remains high due to continued
investments in personnel and additional costs of employee retention and
recruiting initiatives.  These additional costs are associated with the planned
relocation of the Company's monitoring facility as part of the move of the
Company's headquarters to Framingham, Massachusetts.  The Company is also
incurring higher costs associated with continued systems enhancements to support
its current service infrastructure pending the introduction of its approximately
$12 million new call center platform.  Through September 30, 1998, the Company
has invested nearly $10.0 million towards this new platform.  Cost of services
is expected to be impacted, commencing in 1999, by the depreciation of these
investments.

Cost of sales was 27% of net product sales for the three and nine months ended
September 30, 1998, as compared with 26% and 27% for the same respective periods
a year ago.  The Company continues to strive to maintain its cost of sales at a
consistent percentage, although the Company believes that cost of sales will
increase as a percentage of net product sales as net product sales continue to
decline.

Selling, general, and administrative expenses decreased as a percentage of total
revenues to 39% for the three and nine months ended September 30, 1998 as
compared to 41% and 43% of total revenues for the same respective periods in
1997.  The improvement in selling, general, and administrative expenses is
mainly due to the Company effectively reducing such costs as a percentage of
total revenues in 1998, coupled with the significant decrease in amortization
expense because of the write-off of goodwill, reflected in the reorganization
charge taken in the fourth quarter of 1997.  The dollar increase in actual
expenses to $18.7 million for the nine months ended September 30, 1998 from
$17.9 million for the same period in 1997 was largely attributable to salaries
and related fringe benefits due to the overall increase of the Company's
employee base.  The Company now employs approximately 600 employees, 20% more
than the nearly 500 employees at September 30, 1997.

Research and development expenses were 2% of total revenues for the quarter and
nine months ended September 30, 1998 as compared to 3% of total revenues for the
quarter and nine months ended September 30, 1997.  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 for the remainder of 1998.

The Company's effective tax rate was 40.2% for the nine months ended September
30, 1998  compared to 39.5% for the nine months ended September 30, 1997.  The
increase in the Company's rate was mainly due to the decrease of tax exempt
interest income from the Company's marketable securities portfolio.

LIQUIDITY AND CAPITAL RESOURCES

During the nine months ended September 30, 1998, the Company's portfolio of
cash, cash equivalents, and investments increased $3.7 million to $11.6 million
at September 30, 1998 from $7.9 million at December 31, 1997.  The increase was
mainly attributable to profitable operations of $8.5 million and enhanced
collection efforts during 1998 on its accounts receivable portfolio resulting in
cash flow of approximately $1.0 million.  These cash flows were in part offset
by continued purchases of property and equipment of $5.5 million for the first
nine months of 1998.  These purchases were associated with the continued
development of the Company's new response center platform at its primary
monitoring facility, Company-owned equipment provided directly to customers
under comprehensive service agreements and to subscribers not serviced by local
Lifeline programs, and expenditures associated with the Company's anticipated
move to a new corporate facility.  With the growth of the Company's leasing
portfolio, it also had a net cash outlay of approximately $1.3 million for the
nine months ended September 30, 1998 to fund this program.

In 1998, the Company will continue to use its cash and marketable securities as
it continues to invest approximately $12 million in its new response center
platform.  The Company has invested nearly $10.0 million through September 30,
1998 and anticipates it will spend the remaining balance through the first
quarter of 1999 as it develops a flexible, scaleable, and fault tolerant
response center platform at its primary monitoring facility to support its
growing subscriber base.

In April, 1998, the Company obtained a $10.0 million line of credit.  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 obtain additional debt financing.  This line of credit
matures on June 30, 2004, and no amounts were outstanding as of September 30,
1998.

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 expects to occupy this new facility beginning in early 1999.  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
has spent approximately $450,000 through September 30, 1998 for capital
expenditures associated with the move and expects to spend an additional $2.0
million for capital expenditures associated with the move through the first
quarter of 1999.

In October, 1998, the Company entered into a five-year lease to rent an
additional 16,000 square feet of a facility located in Framingham, MA for its
repair, shipping and receiving departments.  The Company intends to occupy this
new facility in early 1999.  Annual rental payments will be approximately
$79,000.  The lease contains two five-year options to renew at the end of the
initial lease term.

In July, 1998, the Company's Board of Directors adopted a Shareholder Rights
Plan in which common stock purchase rights will be distributed as a dividend at
the rate of one Right for each share of the Company's Common Stock outstanding
as of the close of business on August 3, 1998.  This plan was adopted as a means
of deterring possible coercive or unfair takeover tactics and to prevent a
potential acquirer from gaining control of the Company without offering a fair
price to all of the Company's shareholders.  In connection with the Merger
Agreement described below an amendment 

                                      -11-
<PAGE>
 
to this Rights Plan was adopted on October 18, 1998, providing, in part, that
Protection One and its Affiliates are not Acquiring Persons, that no
Distribution Date, Stock Acquisition Date, or Triggering Event shall be deemed
to have occurred, and that no holder of Rights is entitled to exercise such
Rights (as all such terms are defined in the Rights Plan), by virtue of the
execution of the Merger Agreement. Unless the Rights are redeemed or exchanged
earlier, they will expire on July 24, 2008.

The Company expects that funding requirements for operations and in support of
future growth will be met primarily from operating cash flow, and existing cash
and short term investments.  The Company expects these sources will be
sufficient to finance the cash needs of the Company through 1999 including the
continued investment in its new response center platform, the 1999 move to its
new corporate headquarters, the requirements of its internally funded lease
financing program, potential acquisitions, stock repurchases, and other
investments in support of its current business.

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 management's 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.

SUBSEQUENT EVENT

The Company entered into an Agreement and Plan of Merger (the "Merger
Agreement"), dated as of October 18, 1998 with Protection One, Inc. and a
subsidiary of Protection One, Inc. (the "Merger Sub"), pursuant to which,
subject to the terms and conditions of the Merger Agreement, the Company will be
merged with and into the Merger Sub.  In connection with the merger, each share
of the Company's common stock will be converted into the right to receive $14.50
plus a certain number of shares of the common stock of a newly formed holding
company for Protection One, based on the average closing price of Protection
One's common stock prior to the consummation of the transaction and adjusted for
a variable exchange rate.  The number of shares of Protection One holding
company common stock to be received by the company's stockholders will be based
on the average closing price of Protection One common stock for the ten days
ending three days prior to the company's shareholder meeting to be held in
connection with the transaction (the "Average Closing Price").  The number of
shares of holding company common stock to be received by the Company
shareholders per share of the Company's common stock will be as follows:
 
    (A)  1.7857 if the Average Closing Price is less than $7.00;
    (B)  the quotient obtained by dividing (x) $12.50 by (y) the Average Closing
         Price, if the Average Closing Price is equal to or greater than $7.00
         but less than $8.19;
    (C)  1.5263 if the Average Closing Price is equal to or greater than $8.19
         but less than $9.50;

                                      -12-
<PAGE>
 
    (D)  the quotient obtained by dividing (x) $14.50 by (y) the Average Closing
         Price, if the Average Closing Price is equal to or greater than $9.50
         but less than $11.00; and
    (E)  1.3182 if the Average Closing Price is equal to or greater than $11.00.

Based on the closing stock price of Protection One common stock on October 16,
1998, each share of the Company's common stock would have been converted to the
right to receive shares of holding company common stock worth approximately
$15.24.  The acquisition will be accounted for as a purchase and is intended to
qualify as a tax-free reorganization to the extent of the holding company common
stock received in the transaction.  The merger is conditioned upon, among other
things, approval by shareholders of the Company and Protection One, and
expiration or termination of the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976.  The Merger Agreement has been approved by
the boards of directors of Protection One and the Company, and the merger is
expected to be completed in early 1999.

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 entered into the Merger Agreement with Protection One, Inc. and a
subsidiary of Protection One, Inc. (the "Merger Sub"), pursuant to which,
subject to the terms and conditions of the Merger Agreement, the company will be
merged with and into the Merger Sub and the outstanding capital stock of the
Company will be converted into the right to receive $14.50 plus a certain number
of shares of the common stock of a newly formed holding company for Protection
One.  The Merger is conditioned upon, among other things, approval by
shareholders of the Company and Protection One, and expiration or termination of
the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, and, accordingly, there can be no assurance that the Merger will be
consummated.  If the Merger is not consummated, there can be no assurance that
the Company's results of operations and financial condition will not have been
adversely affected by the Merger negotiations or the announcement of the Merger,
or by other factors.

Pursuant to the Merger Agreement, the outstanding capital stock of the Company
will be converted into the right to receive $14.50 plus a certain number of
shares of the common stock of a newly formed holding company for Protection One.
As a result, if the Merger is consummated, stockholders of the Company will
become stockholders of the holding company, and as such will have the risks
associated with an investment in that company.

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 

                                      -13-
<PAGE>
 
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.

The Company is in the process of developing its new call center platform and 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 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 anticipates moving to new corporate headquarters beginning in early
1999.  The new facility is approximately 20 miles from the Company's current
headquarters.  There can be no assurance that the move will not have a material
adverse effect on the Company's business, financial condition or results of
operations, including as a result of employee attrition, and the Company is
actively addressing potential issues.

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 business, financial condition, or 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.

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.

                                      -14-
<PAGE>
 
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 1999 move to new corporate headquarters, or
other similar events or for any other reason, could have a material adverse
effect on the Company's business, financial condition, or results of operations.

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.
In particular, the Company believes that its move to new headquarters in early
1999 may result in employee resignations and is actively addressing this
possibility.

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, an inability to respond to subscriber calls, send invoices,
or engage in similar normal business activities.

The Company has implemented a formal six-phase Year 2000 program to determine
the extent of its own Year 2000 exposures.  The Awareness Phase is ongoing and
involves continuous communication, both internally and externally with customers
and vendors.  The Assessment Phase identifies the Company's products, services
and equipment which contain micro-controllers, as well as all information
technology hardware and software to identify two-digit year exposures.  The
Planning Phase is the Company's decision-making phase, and it prioritizes the
schedule of resolutions to be implemented.  In the Resolution Phase, the Company
will modify, replace or retire systems where necessary.  The Testing Phase tests
the Company's readiness to roll out its results.  Finally the Rollout Phase
implements the entire process into production.

The Company has utilized internal resources to test all products that it
currently manufactures for Year 2000 issues.  This product testing phase has
revealed only minor product behaviors in date keeping that do not, in the
Company's judgment, cause operational failure relating to the year 2000.  The
Company has provided its customers with written information on how to correct
such Year 2000 conditions.

The Company's information technology systems, which include its networks,
desktops, data servers and applications, are being analyzed and tested for Year
2000 compliance. The Company has designed its new call center platform to be in
compliance with the Year 2000.  The Company is currently completing the
Assessment Phase of its remaining information technology systems.  Of all of the
Company's material systems, software replacements and upgrades in the ordinary
course of business (without acceleration for Year 2000 issues) have enhanced the
Company's Year 2000 readiness without incremental costs. Of its existing desktop
computers, the Company believes that  approximately 90% are Year 2000 compliant
with the remaining 10% requiring some modification to ensure Year 2000
compliance.  The Company anticipates that these Year 2000 modifications will be
completed during 1999.

                                      -15-
<PAGE>
 
The Company is moving to new corporate headquarters in early 1999.  As part of
this process, the Company is confirming that all embedded systems contained in
its new building, such as its elevators, heating, air conditioning and security
systems, are Year 2000 compliant.

The Company has categorized its manufacturing equipment and systems as either
mission-critical or non-mission-critical.  To date, the Company believes that
its mission-critical equipment and systems are Year 2000 ready.  All of the
identified non-mission-critical manufacturing equipment and systems are either
not affected by the Year 2000 issue or are deemed to be Year 2000 ready.

The Company is completing its assessment of whether third parties with whom it
has significant relationships are Year 2000 compliant.  The Company sent formal
communications to third parties to determine the extent to which the Company is
vulnerable in the event those third parties fail to resolve their own Year 2000
issues.   Responses to these letters are still being received, but of those
received to date, such third parties have informed the Company that they believe
they are or will be Year 2000 ready.  However, there can be no assurance that
the systems of these companies on which the Company's systems rely will not
experience problems associated with the Year 2000 and, if so, that such problems
would not have a material adverse effect on the Company's business, financial
condition, or results of operations.

The Company is in the process of identifying its most reasonably likely worst
case Year 2000 scenario and developing contingency plans to minimize its
exposure to such scenario.  These plans could result in some expenditures, the
exact amount of which is not known at this time.  The contingency plans are
expected to focus on preparing the Company for the inability of key third-party
suppliers to resolve their own Year 2000 issues and the need to develop
alternative suppliers.

Through September 30, 1998, the Company has had only limited expenditures
related to Year 2000 issues, consisting principally of personnel costs incurred
in the scope of normal operations.  The costs of the Year 2000 project and the
date on which the Company plans to complete the Year 2000 modifications,
estimated to be during 1999, are based on management's best estimates, which
were derived utilizing numerous assumptions of future events including the
continued availability of certain resources, third party modification plans and
other factors.  However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those plans.  Specific
factors that might cause such material differences include, but are not limited
to, the availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes, and similar uncertainties.

The Company believes that its principal Year 2000 risk is significant
interruptions in basic services, such as telephone service and electricity,
caused by third party suppliers that do not resolve their own Year 2000 issues.
These disruptions could have a material adverse effect on the Company's
monitoring operations, and accordingly, its business, financial condition or
results of operations.

Based upon the Company's current progress in becoming Year 2000 ready, the
Company believes it will complete necessary Year 2000 modifications and
contingency plans during 1999.  However, there can be no assurance that the
Company will not need to incur material costs in order to complete

                                      -16-
<PAGE>
 
necessary modifications and to develop and implement contingency plans to
minimize its exposure to the Year 2000 problem. Any such costs, if incurred, or
the Year 2000 problems of third parties with whom the Company has significant
relationships, could have a material adverse effect on the Company's business,
financial condition or results of operations.

       This AMENDMENT NO. 1 TO RIGHTS AGREEMENT (the "Amendment") is entered
into as of the 18th day of October, 1998 between Lifeline Systems, Inc., a
Massachusetts corporation (the "Company"), and State Street Bank and Trust
Company, a Massachusetts trust company (the "Rights Agent"). Capitalized terms
not otherwise defined herein shall have the meanings given them in the Rights
Agreement by and between the parties hereto.



                                   RECITALS

       WHEREAS, the Board of Directors has determined that it is in the best
interests of the Company to amend the Rights Agreement as set forth herein
immediately prior to and in connection with the execution of that certain
Agreement and Plan of Contribution and Merger dated as of October 18, 1998, as
the same may be amended from time to time (the "Merger Agreement"), between
Protection One, Inc., a Delaware corporation ( the "Parent"), Protection One
Acquisition Holding Corporation, a Delaware Corporation and wholly-owned
subsidiary of the Parent ("Holdco"), P-1 Merger Sub, Inc., a Delaware
corporation, P-1 Merger Sub, Inc., a Massachusetts corporation and a wholly-
owned subsidiary of the Holdco ("Merger Sub") and the Company (pursuant to which
Merger Agreement, among other things, the Merger Sub shall merge with and into
the Company and the Company shall become a wholly-owned subsidiary of Holdco).


       WHEREAS, the Company has requested that the Rights Agreement be amended
in accordance with Section 27 of the Rights Agreement, as set forth herein, and
the Rights Agent is willing to amend the Rights Agreement as set forth herein.



                                 AGREEMENT

       NOW, THEREFORE, the parties, intending to be legally bound, hereby agree
as follows:


1.   Section 1(n) of the Rights Agreement is hereby amended to read in its
     entirety as follows:

          "(n)  "Exempted Person" shall mean (i) any Person which, together with
     its Affiliates, had reported Beneficial Ownership as of the date of this
     Agreement of more than ten percent (10%) of the shares of Common Stock

                                      -1-

<PAGE>
 
 
     outstanding as of such date on Schedule 13G under the Exchange Act, unless
     and until such time as such Person, together with its Affiliates, directly
     or indirectly, becomes the Beneficial Owner of more than 19.9% of the
     Common Stock then outstanding, in which case such Person shall cease to be
     an Exempted Person, and (ii) the Parent or Holdco (as those terms are
     defined in Section 7(a) hereof), or any Affiliate or Associate of the
     Parent or Holdco, which acquires shares of Common Stock pursuant to the
     Option Agreement or votes shares of Common Stock pursuant to the Voting
     Agreements (as those terms are defined in Section 35 hereof)."


2.   Section 7(a) of the Rights Agreement is hereby amended to read in its
     entirety as follows:

          "(a)  Subject to Section 7(e) hereof, the registered holder of any
     Rights Certificate may exercise the Rights evidenced thereby (except as
     otherwise provided herein including, without limitation, the restrictions
     on exercisability set forth in Section 9(c), Section 11(a)(iii) and Section
     23 hereof) in whole or in part at any time after the Distribution Date upon
     surrender of the Rights Certificate, with the form of election to purchase
     and the certificate on the reverse side thereof duly executed, to the
     Rights Agent at the office of the Rights Agent designated for such purpose,
     together with payment of the aggregate Purchase Price with respect to the
     total number of shares of Common Stock (or other shares, securities, cash
     or other assets, as the case may be) as to which such surrendered Rights
     are then exercisable, at or prior to the earlier of (i) the Final
     Expiration Date, (ii) the time at which the Rights expire as provided in
     Section 13(d) hereof, (iii) the time at which the Rights are redeemed as
     provided in Section 23 hereof (the "Redemption Date"), (iv) the time at
     which such Rights are exchanged as provided in Section 24 hereof, or (v) in
     accordance with the terms of the Agreement and Plan of Contribution and
     Merger dated as of October 18, 1998, as the same may be amended from time
     to time, between Protection One, Inc., a Delaware corporation (the
     "Parent"), Protection One Acquisition Holding Corporation, a Delaware
     corporation and wholly-owned subsidiary of the Parent ("Holdco"), P-1
     Merger Sub, Inc., a Delaware corporation, P-1 Merger Sub, Inc., a
     Massachusetts corporation and a wholly-owned subsidiary of Holdco (the
     "Merger Sub") and the Company (the "Merger Agreement"), pursuant to which
     Merger Agreement, among other things, the Merger Sub shall merge with and
     into the Company and the Company shall become a wholly-owned subsidiary of
     Holdco (the "Merger"), upon the filing of a certificate of merger with the
     Secretary of State of the Commonwealth of Massachusetts (the "Effective
     Time"), immediately prior to such Effective Time (the earliest of (i),
     (ii), (iii), (iv) and (v) being herein referred to as the "Expiration
     Date").


3.  Section 35 of the Rights Agreement is hereby added as follows:

          "Section 35.  Protection One, Inc. Transaction.  Notwithstanding any
                        --------------------------------                      
     provision of this Rights Agreement to the contrary, no Distribution Date,
     Stock Acquisition Date or Triggering Event shall be deemed to have
     occurred, none of Holdco, Parent, Merger Sub or any Affiliate or Associate

                                      -2-

     of Holdco, Parent or Merger Sub shall be deemed to have become an Acquiring
     Person and no holder of Rights shall be entitled to exercise such Rights
     under or be entitled to any rights pursuant to Section 7(a), 11(a)(ii) or
     13(a) of this Rights Agreement by reason of (x) the approval, execution,
     delivery or effectiveness of the Merger Agreement, the Stock Option
     Agreement of even date therewith between the Parent and the Company (the
     "Option Agreement"), or Voting Agreements of even date therewith between
     the Parent and executive officers and directors of the Company (the "Voting
     Agreements") or (y) the consummation of the transactions contemplated under
     the Merger Agreement, the Option Agreement or the Voting Agreements in
     accordance with the terms thereof (including, without limitation the
     Merger, the issuance of Common Stock upon exercise of the Option Agreement
     or the voting of shares of Common Stock pursuant to the terms of the Voting
     Agreements)."


3.   Except as amended hereby, the Rights Agreement shall remain unchanged and
     shall remain in full force and effect.


4.   This Amendment may be executed in any number of counterparts, each of which
     shall be an original, but all of which together shall constitute one
     instrument.

                                      -3-

       IN WITNESS WHEREOF, the parties have caused this Amendment to be executed
by their respective duly authorized representatives as of the date first above
written.

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

      Tenant will also pay without notice, except as required under this
Lease, without any abatement, deduction or set off , as additional rent, the

of accounting hereunder to any other annual period than a Calendar Year, and

6.04  ABATEMENT OF TAXES; TAX INCENTIVES.
      ---------------------------------- 

      Landlord may at any time and from time to time make application to
the appropriate Governmental Authority for an abatement of Taxes. Landlord shall
make such an application at any time tenants occupying more than 60% of the
Rentable Area of the Building under written Occupancy Arrangements directly with
the Landlord request that Landlord do so. Tenant may, with Landlord's approval
not to be unreasonably withheld, from time to time to attempt to secure state
and /or local tax incentives. Landlord shall cooperate with Tenant in its
attempt to secure such incentive If (I) any such application is successful and
(ii) Tenant has made any payment in respect of Taxes pursuant to this Article 6
for the period with respect to which the abatement or tax incentives was
granted, Landlord shall (a) deduct from the amount of the abatement all expenses
incurred by it in connection with the application (b) pay to Tenant Tenant's
Share (adjusted for any period for which Tenant has made a partial payment) of
abatement, with interest, if any, paid by the Governmental Authority on such
abatement and pay or credit to Tenant any incentives attributable solely to
Tenant (c) retain the balance, if any.



6.05  ELECTRIC SERVICE; PAYMENT AS ADDITIONAL RENT.
      -------------------------------------------- 

      The Estimated Cost of Electrical Service if applicable, is Landlord's
estimate of the cost (on the date hereof) of lighting the Premises and operating
Tenant's office equipment.  This estimate is based on information supplied to
Landlord by Tenant and shall be subject to adjustment as hereinafter set forth.
Tenant shall reimburse Landlord for the cost of providing such electrical energy
by paying to Landlord the estimated Cost of Electrical Service.  Tenant shall
pay Landlord (without previous demand therefor) such amount in monthly
installments on the same day on which Basic Rent is due.  If Tenant (a) connects
equipment (i) other than normal office equipment or (ii) which operates in
excess of 120 volts nominal to the Building Distribution System or (b) operates
any such equipment beyond normal operating hours, the Estimated Cost of
Electrical Service shall be increased by an amount which will reflect the cost
to Landlord of the additional electrical service to be furnished by Landlord.
All electricity to Tenant will be measured by separate meters to be installed by
Landlord as part of the Landlord's Work.  All additional risers or other
equipment required for equipment other than normal office equipment or equipment
which operates on 120 volts nominal shall be provided by Landlord, and the cost
thereof shall be paid by Tenant.



6.06  CHANGE IN RATES OR USAGE.
      ------------------------ 

      The Estimated Cost of Electrical Service is based on current rates
for such service and Landlord's good faith estimate of the usage of electricity
by Tenant. If at any time after the date of this Lease, (i) the rates at which
Landlord purchases electrical energy from the

                                      -15-
<PAGE>
 
public utility supplying electrical service to the Building, or any charges
incurred or Taxes payable by Landlord in connection therewith shall be increased
or decreased or (ii) the usage by Tenant exceeds Landlord's estimate thereof,
the Estimated Cost of Electrical Service shall be increased or decreased, as the
case may be, by an amount equal to the estimated increase or decrease, as the
case may be, in Landlord's cost of furnishing the electricity referred to above
as a result of such increase or decrease in rates, charges, taxes or usage.



6.07  LATE PAYMENT OF RENT.
      -------------------- 

      If any installment of basic rent or additional rent is not received
in full within seven (7) days of its due date then, in addition to any other
rights or remedies of the Landlord, upon demand of Landlord, Tenant shall pay
for each month that rental payments are not timely made, a sum equal to four
percent (4%) of each unpaid portion of such monthly installment as a liquidated
damages charge arising out of and occurring as the result of each such late
payment.


      In the event that Tenant makes three or more late payments of rent
during the Term, Landlord may deem such action to constitute an Event of Default
sufficient to terminate (i) the Lease (ii) any provision for exercise by Tenant
of any option rights under the Lease or (iii) both.

      In addition, Landlord shall perform additional tenant fit up work in
the Premises (the "Tenant Fit Up Work") to be specified by Tenant, the quality
of such work to be in compliance with the standards set forth in Exhibit B2.
(Landlord and Tenant agree that all of the work described in Exhibit B2 need not
be undertaken; rather, Exhibit B2 is included merely to describe the standard of
quality for any Tenant Fit Up Work which Tenant chooses to do.)


      Landlord and Tenant shall use reasonable efforts to agree upon a
specific description of the Tenant Fit Up Work, and the reasonable cost thereof
(which Landlord agrees shall be at a competitive price in the marketplace) (the
"Approved Tenant Fit Up Work Cost"), no later than September 1, 1998. Upon
Tenant's written approval of such description and such cost, Landlord shall
perform the Tenant Fit Up Work. Tenant shall pay the Approved Tenant Fit Up Work
Cost either (a) as additional rent as a lump sum, no later than 5 days after the
Term Commencement Date, or (b) by use of the allowance for Special Work
described in the next

                                      -16-
<PAGE>
 
paragraph. Unless Tenant elects otherwise by written notice to Landlord, it
shall be deemed to have elected option (a) described in the immediately
preceding sentence.

      If Landlord agrees to do, at Tenant's request, any Special Work, Tenant
shall pay the amount of Tenant's Cost to Landlord. If requested by Tenant,
Landlord will provide an allowance of $5.00 per Rentable Square Foot to be used
for Tenant Improvement Construction in addition to the Base Building
Construction. This improvement allowance will be amortized over the lease term
at a twelve and a half percent (12 1/2%) rate in addition to the base rental
rate.


7.02  TIME FOR COMPLETION.
      ------------------- 

      Landlord shall use due diligence to have the Premises ready for occupancy
(including both the Landlord's Work and the Tenant Fit Up Work) on or before the

the completion process. If the Landlord has not completed the Landlord's Work
and the Tenant Fit Up Work by 6 months after the Estimated Term Commencement
Date, Tenant may at its option terminate this Lease.

7.04  DELAYS.
      ------ 

      If Landlord shall be delayed in substantially completing the work in
the Premises as the result of:


          (a)    delay in delivery to Landlord of any plans, design work and
                 detailed drawing, or


          (b)    Tenant's requests for Special Work or change to the Working
                 Drawings (notwithstanding Landlord's approval of such changes),
                 or


          (c)    delays in performance by Tenant or any Person employed by
                 Tenant which shall cause delays in the completion of any work
                 to be done by Landlord or which shall otherwise delay the
                 substantial completion of the Premises, or


          (d)    any fault, negligence, omission, or failure to act on the part
                 of Tenant or its agents, contractors, workmen, mechanics,
                 suppliers or invitees,


                 then, in any such event, Premises shall be deemed to be
                 substantially completed on (and the Term Commencement Date
                 shall be) the date the work would have been completed, but for
                 such fault, negligence, omission or failure.

employees or independent contractors, and not to cause or permit any liens
therewith to attach to the Premises and immediately to discharge any such liens
which may so attach.  All construction work done by Tenant, its agents,
employees or independent contractors shall be done in a good and workmanlike
manner and in compliance with all Legal Requirements and Insurance Requirements.

19.01  LANDLORD'S COVENANT.
       ------------------- 

       Provided that an Event of Default has not occurred and is not then
continuing, Tenant shall, subject to the Permitted Exceptions, quietly have and

any Person lawfully claiming by, through or under Landlord.

19.02  SUBORDINATION
       -------------

       This Lease is and shall be subject and subordinate to any mortgage now
or hereafter on the Building and to each advance made or hereafter to be made
under any mortgage, and to all renewals, modifications, consolidations,
replacements and extensions thereof and all substitutions therefore.  This
Section 19.02 shall be self-operative and no further instrument of subordination
shall be required.  In confirmation of such subordination, Tenant shall execute
and deliver promptly any certificate that Landlord or any mortgagee may request.
In the event that any mortgagee shall succeed to the interest of Landlord then,
this Lease shall nevertheless continue in full force and effect and Tenant shall
and does hereby agree to attorn to such mortgagee and to recognize such
mortgagee as its Landlord.  Prior to the execution of this Lease and prior to
Tenant's subordination to any future mortgage, Tenant shall have received an
executed Nondisturbance and Recognition Agreement in form satisfactory to Tenant
from any existing mortgage.



19.03  NOTICE TO MORTGAGEE.
       ------------------- 

       No act or failure to act on the part of Landlord which would entitle
Tenant under the terms of this Lease, or by law, to be relieved of Tenant's
obligations hereunder or to terminate this Lease, shall result in a release or
termination of such obligations or a termination of this Lease unless (i) Tenant
shall have first given written notice of Landlord's act or failure to act to
Landlord's mortgagees of record, if any, specifying the act or failure to act on
the part of Landlord which could or would give basis to Tenant's rights; and
(ii) such mortgagees, after receipt of such notice, have had the opportunity to
cure such default within a reasonable time thereafter; but nothing contained in
this Section 19.03 shall be deemed to impose any obligation on any such
mortgagees to correct or cure any such condition. "Reasonable time" as used
above shall mean a period of not less than thirty (30) Business Days and shall
include (but not be limited to) a reasonable time to obtain possession of the
Building if the mortgagee elects to do so and a reasonable time to correct or
cure the condition if such condition is determined to exist.



19.04  OTHER PROVISIONS REGARDING MORTGAGEES.
       ------------------------------------- 

       If this Lease or the Rent due hereunder is assigned to a mortgagee as
collateral security for a loan, no such mortgagee shall be deemed to have
assumed any of Landlord's obligations hereunder solely as a result of said
assignment.  A mortgagee to whom this Lease has been so assigned shall be deemed
to have assumed such obligations only if (i) by the terms of the instrument of
assignment such mortgagee specifically elects to assume such obligations or (ii)
such mortgagee has (a) foreclosed its mortgage, (b) accepted a deed in lieu
thereof, or (c) taken possession of the Premises by entry or otherwise.  Even if
such mortgagee assumes the obligations of Landlord hereunder, (i) any such
obligation under Section 24.01 to return the Security Deposit to the Tenant
shall be limited to the amount actually received by the mortgagee with respect
thereto, and (ii) such mortgagee will be liable for breaches of any

                                      -29-
<PAGE>
 
Landlord's obligations hereunder only to the extent such breaches occur during
the period of ownership by the mortgagee after foreclosure (or any conveyance by
a deed in lieu thereof), all as set forth in Section 25.10. hereof.

20.01  DEFAULTS.
       -------- 

       The following shall, if any requirement for notice or lapse of time or
both has not been met, constitute Defaults, and, if such requirements for notice
or lapse of time have been met, constitute Events of Default hereunder:


          (1)    Occurrence of any event set forth in Article 21 hereof;



          (2)    The failure of Tenant to pay Rent when the same shall be due
                 and payable and the continuance of such failure for a period of
                 ten (10) days after receipt by Tenant of notice in writing from
                 Landlord specifying such failure;


          (3)    The failure of Tenant to observe any covenant made by it in
                 Sections 13.01, 15.01 and 25.03 hereof and;


          (4)    The failure of Tenant to keep, observe or perform any of the
                 other covenants, conditions and agreements herein contained on
                 Tenant's part to be kept, observed or performed and the
                 continuance of such failure without the curing of same for a
                 period of thirty (30) days after receipt by Tenant of notice in
                 writing from Landlord specifying in reasonable detail the
                 nature of such failure.



20.02  TENANT'S BEST EFFORTS.
       ----------------------

       In the event that the Default of which Landlord gives notice is of
such a nature that it cannot be cured within such thirty (30) day period, then
such Default shall not be deemed to be an Event of Default so long as Tenant,
after receiving such notice, proceeds to cure the Default as soon as reasonably
possible and continues to take all steps necessary to complete the same within a
period of time which, under all prevailing circumstances, shall be reasonable.
No Default shall be deemed to be an Event of Default if and so long as Tenant
shall be so proceeding to cure the same in good faith or be delayed in or
prevented from curing the same by reason of Force Majeure.

20.03  ELIMINATION OF DEFAULT.
       -----------------------

       Notwithstanding anything to the contrary contained in this Article 20,
in the event that a Default has been cured as hereinabove provided, such
Default(s) shall be deemed never to have occurred and Tenant's rights hereunder
shall continue unaffected by such Defaults.

21.01  INSOLVENCY.
       -----------

       If (1) there occurs with respect to Tenant an Insolvency or (2) any
execution or attachment is issued against Tenant or any of its property and as a
result thereof the Premises are taken or occupied by some Person other than the
Tenant, except as may herein be permitted, then an Event of Default hereunder
shall be deemed to have occurred so that the provisions of Article 22 hereof
shall become effective and Landlord shall have the rights and remedies provided
for therein.

22.01  LANDLORD'S REMEDIES.
       ------------------- 

       If an Event of Default shall occur and be continuing, Landlord may, at
its option, give to Tenant a notice terminating this Lease upon a date specified
in such notice, which date shall be not less than three (3) Business Days after
the date of receipt by Tenant of such notice from Landlord, and upon the date
specified in said notice, the term and estate hereby vested in Tenant shall
cease and any and all other right, title and interest of Tenant hereunder shall
likewise cease without further notice or lapse of time, as fully and with like
effect as if the entire Lease Term had elapsed, but Tenant shall continue to be
liable to Landlord as hereinafter provided.


       If such Event of Default results from Tenant's failure to pay Tenant's
Cost as required by Section 7.01 hereof, Landlord may, at its option, in
addition to or in lieu of the other remedies available to Landlord, refuse
Tenant access to the Premises. In such event the Term Commencement Date shall be
the earlier of (i) the date determined in accordance with Section 7.04 or (ii)
the Substantial Completion Date.
 

       If such Event of Default results from Tenant's failure to pay a charge
for an Additional Service pursuant to Section 8.03 hereof, Landlord may, without
further notice to Tenant, discontinue any or all of such Additional Services.

                                      -31-
<PAGE>
 
       If an Event of Default shall occur and be continuing, Landlord shall
be relieved of its undertakings under Articles 7, 8, 13, 17, 18, 19, and 26
hereof.


22.02  SURRENDER.
       --------- 

       Upon any termination of this Lease as the result of an Event of Default,
Tenant shall quit and peacefully surrender the Premises to Landlord, upon or at
any time after any such termination, Landlord may without further notice enter
the Premises and possess itself thereof by summary proceedings or otherwise, and
may dispossess Tenant and remove Tenant and all other Persons and property from
the Premises and may have, hold and enjoy the Premises and the right to receive
all rental income of and from the same.



22.03  RIGHT TO RELET.
       -------------- 

       At any time from time to time after any such termination, Landlord may
relet the Premises or any part thereof, in the name of Landlord or otherwise,
for such terms or terms (which may be greater or less than the period which
would otherwise have constituted the balance of the Lease Term) and on such
conditions (which may include concessions or free rent) as Landlord, in its
reasonable discretion, may determine and may collect and receive the rents
therefor.  Landlord shall in no way be responsible or liable for any failure to
relet the Premises or any part thereof, or for any failure to collect any rent
due upon any such reletting provided that Landlord will use reasonable efforts
to mitigate.



22.04  SURVIVAL OF COVENANTS.
       --------------------- 

       No such termination of this Lease shall relieve Tenant of its
liability and obligations under this Lease and such liability and obligations
shall survive any such termination (but mitigated by any re-letting).  Tenant
shall indemnify and hold Landlord harmless from all loss, cost, expense, damage
or liability arising out or in connection with such termination.


       In the event of any such termination, Tenant shall pay to the Landlord
the Rent up to the date of such termination.  Tenant shall also pay to Landlord,
on demand, as and for liquidated and agreed damages for Tenant's Default, the
difference between



       (1)    the aggregate Rent which would have been payable under this Lease
              by Tenant from the date of such termination until the Stated
              Expiration Date, less
                               ----

       (2)    the fair and reasonable rental value of the Premises for the same
              period, excluding all of Landlord's reasonable estimate of
              expenses to be incurred in connection with reletting the Premises,
              including, without limitation, all repossess costs, brokerage
              commission, legal expenses, reasonable attorney's fees, alteration
              costs, and expenses of preparation for such reletting.

                                      -32-
<PAGE>
 
       If the Premises or any part thereof are relet by the Landlord in good
faith to an unrelated third party before presentation of proof of such
liquidated damages to any court, commission or tribunal, the amount of rent
reserved upon such reletting shall be, prima facie, the fair and reasonable
                                       -----------                         
rental value for the part or the whole of the Premises so relet during the term
of the reletting.


       Nothing herein contained shall limit or prejudice the right of the
Landlord to prove and obtain as liquidated damages by reason of such
termination, an amount equal to the maximum allowed by any statute or rule of
law in effect at the time when, and governing the proceedings in which, such
damages are to be proved, whether or not such amount be greater, equal to, or
less than the amount of the difference referred to above.



22.05  RIGHT TO EQUITABLE RELIEF.
       ------------------------- 

       If there shall occur a Default or threatened Default, Landlord shall be
entitled to enjoin such Default or threatened Default and shall have the right
to invoke any right and remedy allowed at law or in equity or by statute or
otherwise as though re-entry, summary proceedings, and other remedies were not
provided for in this Lease.



22.06  RIGHT TO SELF HELP;  INTEREST ON OVERDUE RENT.
       --------------------------------------------- 

       If an Event of Default shall occur and be continuing, Landlord shall have
the right, but shall not be obligated, to enter upon the Premises and to perform
such obligation notwithstanding the fact that no specific provision for such
substituted performance by Landlord is made in this Lease with respect to such
Default. In performing such obligation, Landlord may make any payment of money
or perform any other act. The aggregate of (i) all sums so paid by Landlord,
(ii) interest (at the rate of 1 1/2% per month or the highest rate permitted by
law, whichever is less) on such sum plus all Rent not paid when due and (iii)
                                    ----
all necessary incidental costs and expenses in connection with the performance
of any such act by Landlord, shall be deemed to be Rent under this Lease and
shall be payable to Landlord immediately upon demand. Landlord may exercise the
foregoing rights without waiving any other of its rights or releasing Tenant
from any of its obligations under this Lease.



22.07  FURTHER REMEDIES.
       ---------------- 

       Upon any termination of this Lease pursuant to Section 22.01, or at
any time thereafter, Landlord may, in addition to and without prejudice to any
other rights and remedies Landlord shall have at law or in equity, re-enter the
Premises, and recover possession thereof and may dispossess any or all occupants
of the Premises in the manner prescribed by the statute relating to summary
proceedings, or similar statute(s); but Tenant in such case shall remain liable
to Landlord as hereinbefore provided.

23.01  NO WAIVERS.
       ---------- 

       Failure of Landlord to complain of any act or omission on the part of
Tenant no matter how long the same may continue, shall not be deemed to be a
waiver by said Landlord of any of its rights hereunder.  No waiver by any
provision of this Lease shall be deemed a waiver of a breach of the same or any
other provision.  No acceptance by Landlord of any partial payment shall
constitute an accord or satisfaction but shall only be deemed a partial payment
on account.

delay and the period for the performance of any such act shall be extended for a

                                   ---------

                                    PARKING
                                    -------
                                        
Upon Tenant's occupancy of the Premises, it shall have the right to use, as
appurtenant to the Premises, a maximum of 50 parking spaces in Tenant's main
parking area as shown in Exhibit E-1.  Tenant may also use alternate parking
areas shown in Exhibit E-1 until such time when Landlord notifies Tenant that
alternate parking areas are no longer available to Tenant.  All parking areas
shall be on a first-come first-serve basis.  Landlord will repair pavement and
restripe the Building's parking areas to be used by Tenant's employees.
Landlord shall in no event be required to enforce such reserved rights on
Tenant's behalf.  Use of such spaces is limited to Tenant's employees assigned
to the Premises and may not be sold, assigned, licensed or otherwise given to
any person for any compensation or fee or otherwise, except in connection with a
sublease or assignment permitted under the lease.  The use of such parking
spaces by Tenant may be regulated by rules and regulations issued by the
landlord from time to time.  Landlord reserves the right, after reasonable
written notice to Tenant, at any time and from time to time to change the
location of any parking space or spaces designated for tenant's use pursuant to
this section. Notwithstanding the immediately preceding sentence, however, in
the event that Landlord, in the future, dedicates any parking spaces in the
areas shown in Exhibit E-1 for the exclusive use of any other tenant (the "Other
Tenant Spaces") such that less than 50 parking spaces are available for Tenant's
use in Tenant's Main Parking Area, then Tenant shall have the right to have
dedicated for Tenant's exclusive use, 50 parking spaces, mutually agreed upon by
Tenant and Landlord from the parking areas shown in Exhibit E-1, but excluding
the Other Tenant Spaces.
