                                   ----------

         WHEREAS, the Board of Directors of thc Company (the "Board") has
determined that it is appropriate and in the best interests of the Company and

         WHEREAS, the Executive is a party to the "Employment Agreement" with
the Company, dated as of October 21, 1997 (the "Prior Employment Agreement");
and

         WHEREAS, the Company and the Executive desire that the Prior Employment
Agreement be terminated, and that the terms and conditions set forth herein
apply to the Executive in connection with his employment with the Company from
and after the date hereof.

         NOW, THEREFORE, in consideration of the mutual covenants and conditions
herein contained and in further consideration of services to be performed by the
Executive for the Company, the Company and the Executive do hereby agree as
follows:

         1. Certain Definitions. For purposes of this Agreement, the following
terms have the meanings indicated:

                (a) "Award" shall mean any award granted pursuant to the terms
         of the Plan and pursuant to the non-Plan Stock Option Agreement dated
         October 15, 1997, including but not limited to stock options, stock

         stock, deferred stock, stock granted as a bonus or in lieu of other
         awards, dividend equivalents, and other stock-based awards.

                (b) "Cause" shall mean: (i) the willful and continued failure by
         the Executive to substantially perform his duties for the Company
         (other than any such failure resulting from the Executive's incapacity
         due to physical or mental illness, or any such actual or anticipated
         failure after the Executive announces his intention to resign for Good
         Reason), and such failure is not cured by the Executive within seven
         days from the date the Company notifies the Executive thereof, (ii) the
         willful engaging by the Executive in misconduct which is materially and
         financially injurious to the Company, or (iii) the Executive's
         conviction of a felony. No act, or failure to act, on the Executive's
         part shall be considered "willful" unless done, or omitted to be done,
         by him not in good faith and without reasonable belief that his action
         or omission was in the best interest of the Company.

                any reason to constitute at least a majority of the members of
                the Board, provided that any individual becoming a director
                subsequent to the effective date of this Agreement whose
                election, or nomination for election by thc Company's
                stockholders, was approved by a vote of at least a majority of
                the directors then comprising the Incumbent Board (other than
                any individual whose nomination for election to Board membership
                was not endorsed by the Company's management prior to, or at the
                time of, such individual's initial nomination for election)

                recapitalization, reorganization, sale or disposition of all or
                a substantial portion of the Company's assets, a reverse stock
                split of outstanding voting securities, the issuance of shares
                of stock of the Company in connection with the acquisition of
                the stock or assets of another entity, provided, however, that a
                Change in Control shall not occur under this clause (iii) if
                consummation of the transaction would result in at least 50% of
                the total voting power represented by the voting securities of
                the Company (or, if not the Company, the entity that succeeds to
                all or substantially all of the Company's business) outstanding
                immediately after such transaction being beneficially owned
                (within the meaning of Rule 13d-3 promulgated pursuant to the
                Exchange Act) by at least 50% of the holders of outstanding
                voting securities of the Company immediately prior to the
                transaction, with the voting power of each such continuing
                holder relative to other such continuing holders not

         because of Disability, the question of the Executive's Disability shall
         be subject to the certification of a qualified medical doctor agreed to
         by the Company and the Executive or, in the event of the Executive's
         incapacity to designate a doctor, the Executive's legal representative.
         In the absence of agreement between the Company and the Executive (or
         the Executive's representative, as the case may be), each party shall
         nominate a qualified medical doctor and the two doctors shall select a
         third doctor, who shall make the determination as to Disability.

         responsibilities and/or status, or any removal of the Executive from or
         any failure to reelect the Executive to any of such positions; or (ii)
         any reduction by the Company in the Executive's base salary as in
         effect on thc date hereof or as the same may be increased from time to
         time; or (iii) any failure by the Company to continue in effect as to
         the Executive, without a substantially comparable replacement, any
         material compensation or benefit plan or program in which the Executive
         was participating; or (iv) any attempted relocation of the Executive's
         place of employment to a location more than 50 miles from the location

the Executive from the Company for Good Reason, the Company shall pay or provide
to the Executive the following:

                (a) any earned and accrued but unpaid installment of base salary
         through the date of the Executive's resignation or termination at the
         rate in effect at the time of such resignation or termination (or, if
         greater, immediately prior to the occurrence of an event that
         constitutes Good Reason) and all other unpaid amounts to which the
         Executive is entitled as of such date under any compensation plan or
         program of the Company, including, without limitation, all accrued
         vacation time; such payments to be made in a lump sum within 30 days
         following the date of resignation or termination; and

                (b) in lieu of any further salary payments to the Executive for

         year following the date of the Executive's resignation or termination,
         for the continued benefit of the Executive, all employee

<PAGE>

         was entitled to participate immediately prior to the Executive's
         resignation or termination, provided that the Executive's continued
         participation is possible under the general terms and provisions of
         such plans and programs. In the event that the Executive's
         participation in any such plan or program is barred, the Company shall,
         at its sole cost and expense, arrange to provide the Executive with
         benefits substantially similar to those which the Executive would
         otherwise have been entitled to receive under such plans and programs
         from which his continued participation is barred; and

                (d) with respect to any Award granted to the Executive pursuant
         to the Plan and/or pursuant to the non-Plan Stock Option Agreement
         dated October 15, 1997, which is subject to future vesting and/or other
         restrictions regarding the exercisability or full enjoyment of the
         Award as of the date of the Executive's resignation or termination (if
         any), then, notwithstanding the terms of the Plan or the certificate
         evidencing the Award thereunder, the continued vesting or lapse of
         restrictions with respect to such Award shall not cease with reference
         to such termination or resignation, but shall continue during the
         duration of the term of the Award in accordance with the schedule set
         forth in the certificate evidencing such Award as if the Executive's
         employment with the Company had continued throughout such vesting
         and/or lapse of restriction period. In addition, with respect to each
         Award granted to the Executive pursuant to the Plan or pursuant to the
         non-Plan Stock Option Agreement dated October 15, 1997, (whether or not
         fully vested or free of restrictions at the time of termination or
         resignation hereunder), the exercisability and the full enjoyment of
         such Award shall not terminate with reference to such termination or
         resignation, but shall be extended for the duration of the entire term
         of the Award in accordance with the Plan and/or non-Plan Stock Option
         Agreement dated October 15, 1997, and/or the certificate evidencing
         such Award as if the Executive's employment with the Company had
         continued during such entire term, notwithstanding the terms of the
         Plan or non-Plan Stock Option Agreement or the certificate evidencing
         the Award thereunder.

         3. Termination for Death. In the event of the termination of the
employment of the Executive by reason of his death, the Company shall pay to the
Executive's designated beneficiary or estate the amounts set forth in paragraphs
(a) and (b) of Section 2 above, pursuant to which the date of the Executive's
death shall be considered the date of his termination thereunder. In addition,
with respect to any Award granted to the Executive pursuant to the Plan, in the
event that such Award is subject to future vesting or other restrictions
regarding the exercisability or full enjoyment of the Award as of the date of
the Executive's death, then, notwithstanding the terms of the Plan or the Award
Agreement thereunder, all restrictions thereon shall immediately lapse, and each
such Award shall be deemed immediately and fully vested and exercisable under
the Plan, as of the date of such death.

         4. Termination for Cause or Disability or Resignation without Good
Reason. In the event of the Executive's termination of employment for Cause or
Disability or his resignation without Good Reason, only the amount set forth in
paragraph (a) of Section 2 shall be payable to the Executive, except that, in
the case of the Executive's termination for Disability hereunder, the Executive
shall also receive the benefits set forth in Section 2(d) hereof. Other than in
the case of the Executive's conviction of a felony, the Executive shall not be
deemed to have been terminated for Cause by the Company hereunder without (i)
notice to the Executive setting forth the reasons for the Company's intention to
terminate the Executive for Cause, (ii) an opportunity for the Executive,
together with his counsel, to be heard before the Board, and (iii) delivery to
the Executive of written notice from the Board finding that in the reasonable
good faith opinion of the

                                       4
<PAGE>

Board, the Executive was guilty of conduct set forth in the definition of Cause
in Section 1 hereof, and specifying the particulars thereof in detail.

         5. Termination or Resignation in connection with a Change in Control.

                  (a) Notwithstanding the provisions of Sections 2 and 4, in the
         event of the termination of the employment of the Executive for any
         reason other than death, whether initiated by the Company with or
         without Cause, or initiated by the Executive with or without Good
         Reason, which termination occurs within the one year period following
         the date of a Change in Control, then, in lieu of the amounts and
         benefits specified in Sections 2 and 4, the Executive shall be entitled
         to receive (i) the amount set forth in Section 2(a), (ii) the amount
         set forth in Section 2(b), and (iii) the benefits provided for in
         Section 2(c).

                  (b) Notwithstanding the provisions of Section 2, in the event
         of the resignation or termination of the employment of the Executive
         for any reason specified therein, and such resignation or termination
         occurs within the four month period (i) prior to the date of a Change
         in Control, (ii) following commencement (within the meaning of Rule
         14d-2 as promulgated under the Exchange Act) of a "tender offer" for
         stock of the Company subject to Section 14(d)(2) of the Exchange Act,
         which if consummated, would result in an acquisition described in
         clause (i) of Section l(b), (iii) following the execution by the
         Company of an agreement the consummation of which would constitute a
         Change in Control, (iv) following the solicitation of proxies for the
         election of directors by anyone other than the Company, or (v)
         following the approval by the Company's stockholders of any transaction
         described in Section 1(b)(iii), then, in lieu of the amounts and
         benefits specified in Section 2:

                  (x) the Executive shall be entitled to receive the amounts and
                  benefits specified in Section 5(a), and

                  (y) with respect to any Award granted to the Executive
                  pursuant to the Plan or the non-Plan Stock Option Agreement
                  dated October 15, 1997, in the event that such Award is
                  subject to future vesting or other restrictions regarding the
                  exercisability or full enjoyment of the Award as of the date
                  of such resignation or termination, then, notwithstanding the
                  terms of the Plan or the Award Agreement thereunder, the
                  accelerated vesting and lapse of restriction provisions set
                  forth in Section 4 of the Plan or the non-Plan Stock Option
                  Agreement dated October 15, 1997 shall bc applicable with
                  respect to such Awards as if a Change in Control had occurred
                  on the date of such resignation or termination.

Amounts and benefits payable by reason of clause (b)(i) of this Section 5 shall
be paid within ten days following the date of the Change in Control, but shall
be offset by any amounts previously paid pursuant to Section 2.

         6. Certain Taxes. The Company shall have the right to deduct from any
amounts payable under this Agreement an amount necessary to satisfy its
obligation, under applicable laws, to withhold income or other taxes of the
Executive attributable to payments made hereunder.

                                       5
<PAGE>

         7. No Obligation to Mitigate Damages: No Effect on Other Contractual
Rights. The Executive shall not be required to mitigate damages or the amount of
any payment provided for under this Agreement by seeking other employment or
otherwise, nor shall the amount of any payment provided for under this Agreement
be reduced by any compensation earned by the Executive as the result of
employment by another employer after the date of resignation or termination, or
otherwise. The provisions of this Agreement, and any payment provided for
hereunder, shall not reduce any amounts otherwise payable, or in any way
diminish the Executive's existing rights, or rights the Executive may acquire in
the future, under any employee benefit plan, incentive plan, employment
agreement or other contract, plan or arrangement.

         8. Indemnification. The Company shall indemnify the Executive within 60
days after receipt of a request therefor against all judgments, fines,
settlements, payments and expenses, including reasonable attorneys' fees, paid
or incurred in connection with any claim, action, suit or proceeding, civil,
criminal, administrative or investigatory ("Proceeding"), to which the Executive
may be made a party or with which he may be threatened by reason of his being or
having been an employee, officer or director of the Company or, at the Company's
request, an employee, officer or director of any other corporation, firm,
association or other organization, or by reason of any action or omission by the
Executive in such capacity, whether or not the Executive continues to hold such
position or act in such capacity at the time of incurring such expenses or at
the time the indemnification is made, other than in connection with actions
taken by the Executive which constitute gross negligence in the performance of
his duties for the Company which the Executive has undertaken without the
reasonable good faith belief that such actions were in the best interest of the
Company. The foregoing right of indemnification shall not be exclusive of other
rights to which the Executive may otherwise be entitled. The Company shall pay
the reasonable expenses (including reasonable attorneys' fees) incurred by the
Executive in defending any Proceeding in advance of the final disposition
thereof. The Company shall advance all such expenses by or on behalf of the
Executive within 15 days after receipt of his request therefor, accompanied or
preceded by reasonable evidence of such expenses. The Executive will also be
named as an insured under any directors and officers or similar insurance policy
that the Company may purchase.

         9. Successor to the Company. The Company will require any successor or
assign (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the
Company, by agreement in form and substance satisfactory to the Executive,
expressly, absolutely and unconditionally to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place. For
purposes of clarity, any failure of the Company to obtain such agreement prior
to the effectiveness of any such succession or assignment shall be a material
breach of this Agreement and shall entitle the Executive to terminate the
Executive's employment for Good Reason. As used in this Agreement, the term
"Company" shall mean the Company as hereinbefore defined and any successor or
assign to its business and/or assets as aforesaid which executes and delivers
the agreement provided for in this Section 9 or which otherwise becomes bound by
all the terms and provisions of this Agreement by operation of law.

         10. Enforcement.

                  (a) This Agreement shall inure to the benefit of and be
         enforceable by the Executive's personal and legal representatives,
         executors, administrators, successors, heirs, distributees,

                                       6
<PAGE>

         devisees and legatees. If the Executive should die while any
         amounts are still payable to him hereunder, all such amounts shall be
         paid in accordance with the terms of this Agreement to the Executive's
         estate or beneficiary.

                  (b) In the event that the Company shall fail or refuse to make
         payment of any amounts due the Executive hereunder within the
         appropriate time period, the Company shall pay to the Executive, in
         addition to the payment of any other sums provided in this Agreement,
         interest, compounded daily, on any amount remaining unpaid from the
         date payment is required until paid to the Executive, at the rate from
         time to time announced by Chase Manhattan Bank as its "prime rate" plus
         2%, each change in such rate to take effect on the effective date of
         the change in such prime rate.

                  (c) The Company shall pay all reasonable fees and expenses
         (including attorneys' fees) that the Executive may incur as a result of
         the Company's contesting the validity, enforceability, or the
         Executive's interpretation of, this Agreement (regardless of the
         outcome of any litigation to enforce this Agreement).

         11. Non-Competition.

                  (a) The Executive hereby acknowledges that the services which
         he will perform for the Company are of a special and unique nature, and
         that the Company would find it extremely difficult or impossible to
         replace the Executive. Accordingly, the Executive agrees that, in
         consideration of this Agreement and the payments to be received by him
         hereunder in the event the occurrence of certain actions as specified
         herein, the Executive will not (i) from and after the date hereof
         through the period during which the Executive continues to be employed
         by the Company (the "Employment Period"), and (ii) in the event of the
         Executive's termination or resignation hereunder pursuant to the
         provisions set forth in Sections 2 and 4 hereof, for the one-year
         period thereafter (the "Non-Competition Period"), directly or
         indirectly, own, manage, operate, join, control or participate in the
         ownership, management, operation or control of, or be connected as a
         director, officer, employee, partner, lender, consultant or Otherwise
         ("Participate" or a "Participation") with, any business or organization
         in any part of the United States in which the Company sells products or
         provides services, which Competes with the Company (as hereinafter
         defined), except with the Company's prior written consent. For purposes
         of this Agreement, a business or organization shall be deemed to
         "Compete with the Company" if such business or entity is engaged in the
         residential and/or commercial security business, and the residential
         and/or commercial security business constitutes the majority of such
         business or organization's business operations; provided, however, that
         with respect to a business or organization in which the residential
         and/or commercial security business constitutes less than the majority
         of such business or organization's business operations, the Executive
         shall be prohibited hereunder from Participating in the division,
         segment or other portion of such business or entity which is engaged in
         the residential and/or commercial security business during the
         Non-Competition Period. Nothing in this paragraph shall prohibit the
         Executive from owning for investment purposes an aggregate of up to 3%
         of the publicly traded securities of any corporation listed on the New
         York or American Stock Exchange or whose securities are quoted on the
         NASDAQ National Market, provided that there shall be no limitation on
         the percentage of ownership of the Company or any

                                       7

         successor thereto that may be owned by the Executive hereunder.
         Notwithstanding anything which may be to the contrary herein, the
         Executive shall not be required to cease Participation in any business
         or organization which begins to Compete with the Company subsequent to
         the time when the Executive commences such Participation, provided that
         such business or organization began to Compete with the Company through
         no action, assistance, or plan of the Executive.

                  (b) It is the desire and intent of the parties that the
         provisions of Section 11 of this Agreement shall be enforced under the
         laws and public policies applied in each jurisdiction in which
         enforcement is sought. Accordingly, if any particular provision of
         Section 11 of this Agreement is adjudicated to be invalid or
         unenforceable or shall for any reason be held to be excessively broad
         as to duration, geographic scope, activity or subject, it shall be
         construed by limiting and reducing it, so as to be enforceable to the
         extent compatible with applicable law and such provision shall be
         deemed modified and amended to the extent necessary to render such
         provision enforceable in such jurisdiction.

                  (c) In the event of a breach or threatened breach by the
         Executive of the provisions of Section 1 l(a), in addition to other
         remedies available to the Company at law (the amount of which shall be
         limited by this Section 11 (c)) or in equity, the Company shall be
         entitled to a temporary or permanent injunction or injunctions, or
         temporary restraining orders or orders to prevent breaches thereof, in
         each case, without the need to post any security or bond. All remedies
         available for breach of this Agreement are cumulative, and the pursuit
         of any remedy shall not be construed as an election of such remedy or
         as prohibiting the Company from or limiting the Company in pursuing any
         other remedies available for any breach or threatened breach of this
         Agreement. The parties hereto agree and stipulate in advance that in
         any action brought by or on behalf of the Company to recover damages
         against the Executive for a breach of the provisions of Section 11(a)
         hereof, the maximum damages that may be awarded in the event that the
         Executive is ultimately adjudged to have breached such provisions shall
         be limited to the Executive's most recent annual salary multiplied by a
         fraction, the numerator of which shall be the number of full months
         that the Executive was finally adjudged to have been in breach of this
         covenant, and the denominator of which shall be twelve.

         12. Confidentiality. The Executive acknowledges that the Company will
be engaged in a business involving Confidential Information (as hereinafter
defined) that is proprietary to the Company. In addition, the Executive
acknowledges that through employment with the Company, he will have access to,
and will acquire or assist in the development of, Confidential Information
regarding the Company and its technologies, customers and plans, the disclosure
of which to others would cause the Company to suffer substantial damage. In
consideration of the obligations undertaken by the Company as set forth herein,
the Executive will not, at any time during or after the Employment Period,
publish, disclose or use, or authorize any other person or entity to publish,
disclose or use, any Confidential Information of or about the Company of which
the Executive has already become, or becomes, aware or informed during his
employment with the Company, whether or not developed by him, except (i) as
required by law (including but not limited to judicial or administrative
process), (ii) in the performance of the Executive's duties for the Company, or
(iii) in the event that the Confidential Information becomes generally known to
the public through no actions (either directly or indirectly) of the Executive.
For purposes hereof, the term "Confidential Information" shall include, without
limitation, matters of a technical nature, "know-how," formulas, secret
processes, works of authorship, computer programs, materials, patent
applications, new

                                       8

         product plans, technical improvements, test data, progress reports and
         research projects, and matters of a business nature, such as business
         plans, prospects, financial information, marketing plans and
         strategies, proprietary information about costs, profits, markets,
         sales, lists of customers and suppliers of the Company, procurement and
         promotional information, credit and financial data concerning customers
         or suppliers of the Company, information relating to the management and
         operation of the Company, and other information of a similar nature to
         the extent not available to the public.

         13. Non-Solicitation. During (a) the Employment Period, and (b) in the
event of the Executive's termination or resignation hereunder pursuant to the
provisions set forth in Sections 2 and 4 hereof, for the two-year period
thereafter (the "Non-Solicitation Period"), the Executive shall not, directly or
indirectly (i) solicit, entice or induce any individual that currently (i.e.,
currently at the time of any such restricted action during the Non-Solicitation
Period) is an employee of the Company to become employed by any individual,
business or entity other than the Company, or (ii) approach any such employee
for such purpose, or authorize or participate or assist with the taking of such
actions by any other individual, business or entity.

         14. Notice. For purposes of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be

at any time of any breach by the other party hereto of, or compliance with, any
