AGREEMENT,  made  as of  this  13th  day of  May,  1996  by and  between  Holmes
Protection Group, Inc. (the "Company") and Lawrence R. Irving ("Executive")

                                   WITNESSETH:

WHEREAS, the Company is engaged in the business of providing central station
burglar and fire alarm protection services and of providing management services
to affiliated companies (the "Business");

WHEREAS, Executive has represented that he has the expertise, background and
experience to enable him to perform all of the duties and execute all of the
responsibilities contemplated by this Agreement;

WHEREAS, based on such representation, the Company wishes to employ Executive
upon the terms hereinafter set forth; and

WHEREAS, Executive wishes to be so employed by the Company;

NOW, THEREFORE, in consideration of the premises and the mutual convenants and
agreements herein contained, the Company and Executive agree as follows:

1.   Employment. The Company hereby agrees to employ Executive, and Executive
     hereby agrees to be employed and serve, subject to the provisions of this
     Agreement, as the Vice President - Finance of the Company. Executive shall
     perform such duties and responsibilities as are from time to time assigned
     to Executive by the Chief Executive Officer of the Company (the "CEO"), to
     whom Executive shall report. Executive agrees to devote all of his business
     time, attention and energies to the performance of the duties assigned to
     him hereunder, and to perform such duties faithfully, diligently and to the
     best of his abilities and subject to such laws, rules, regulations and
     policies from time to time applicable to the Company's employees, including
     but not limited to the Company's Code of Practice for Purchase of Shares.
     Executive agrees to refrain from engaging in any activity that does, will
     or could reasonably be deemed to conflict with or be detrimental to the
     best interests of the Company.

 2.  Term. This Agreement and Executive's employment hereunder shall commence as
     of May 13, 1996 and shall expire on May 31, 1998 (the "Term"), unless
     sooner terminated in accordance with Section 8 hereof; provided, however,
     unless so terminated, such employment shall continue year-to-year
     thereafter, subject to said Section 8 (such continued period being included
     hereunder as the "Term").



3.   Compensation

     (a) Salary. Executive's salary shall be at the rate of no less than
     $105,000 payable in accordance with the Company's regular payroll
     practices. All applicable withholding taxes shall be deducted from such
     payments. Salary reviews will be conducted no less than annually.

     (b) Options. Subject and pursuant to the terms of a new stock option plan
     to be prepared and submitted by the Company for shareholder approval at the
     Company's 1996 Annual Meeting of Shareholders, and their approval thereof,
     the Company hereby agrees to grant to Executive a non-statutory option to
     purchase 25,000 shares of the Company's common stock, at an exercise price
     equal to the Fair Market Value (to be defined in said plan) of such shares
     on May 6, 1996. 5,000 options of the options granted pursuant hereto shall
     vest immediately upon the approval of said stock plan by the Company's
     shareholders as aforesaid, and 5,000 shall vest on each May 6th of the
     years 1997 to 2000. Provided, however, that if Executive's employment
     hereunder shall have been terminated by the Company for Cause (as
     hereinafter defined) or voluntarily by Executive without Good Reason (as
     hereinafter defined), prior to any of such dates, all unvested options
     shall immediately terminate upon Executive's termination of employment and
     no longer represent the right to purchase stock of the Company. If
     Executive's employment hereunder is terminated by the Company for any
     reason other than Cause, or by Executive with Good Reason, all unvested
     options shall vest immediately upon the date of such termination. All
     previously vested options, and those that have vested as aforesaid upon
     Executive's termination of employment, shall remain exercisable for three
     (3) months after the date of Executive's termination of employment or for
     such longer period as may be provided in the option agreements pursuant to
     which the options are granted.

4.   Benefits. Executive shall receive the benefits listed in Appendix A hereto,
     which benefits shall be provided to Executive in accordance with the terms
     and conditions of such benefit plans and programs as are maintained by the
     Company for individuals in positions comparable to those of Executive, as
     such plans are amended from time to time.

5.   Vacation.  Executive  shall be entitled to paid  vacation of four (4) weeks
     annually.  Such vacation  shall be taken at such times as will interfere as
     little as possible with the performance of Executive's duties hereunder.

6.   Expenses. The Company will reimburse Executive for reasonable and necessary
     business expenses of Executive for travel, meals and similar items incurred
     in connection with the performance of Executive's duties, and which are
     consistent with such guidelines as the Company may from time to time
     establish. All payments for reimbursement of such expenses shall be made to
     the Executive only upon the presentation to the Company of appropriate
     vouchers or receipts.



7.   Confidentiality, Non-Competition, etc.

     (a) Executive acknowledges that (i) the Business is intensely competitive
     and that Executive's employment by the Company will require that Executive
     have access to and knowledge of but not limited to, the identity of the
     Company's customers, the identity of the representatives of customers with
     whom the Company has dealt, the kinds of services provided by the Company
     to customers and offered to be performed for potential customers, the
     manner in which such services are performed or offered to be performed, the
     service need of actual or prospective customers, pricing information,
     information concerning the creation, acquisition or disposition of products
     and services, customer maintenance listings, computer software applications
     and other programs, personnel information and other trade secrets (the
     "Confidential Information"); (ii) the direct or indirect disclosure of any
     such Confidential Information to existing or potential competitors of the
     Company would place the Company at a competitive disadvantage and would do
     damage, monetary or otherwise, to the Company's business, and (iii) the
     engaging by Executive in any of the activities prohibited by this Section 7
     may constitute improper appropriation and/or use of such information and
     trade secrets. Executive expressly acknowledges the trade secret status of
     the Confidential Information and that the Confidential Information
     constitutes a protectible business interest of the Company. Accordingly,
     the Company and Executive agree as follows:

     (b) For purposes of this Section 7, the Company shall be construed to
     include the Company and its parents, subsidiaries and affiliates engaged in
     the Business.

     (c) During the Term of this Agreement and at all times after the
     termination of Executive's employment by expiration of the Term or
     otherwise, Executive shall not, directly or indirectly, whether
     individually, as a director, stockholder, owner, partner, employee,
     principal or agent of any business, or in any other capacity, make known,
     disclose, furnish, make available or utilize any of the Confidential
     Information, other than in the proper performance of the duties
     contemplated herein. Executive agrees to return all Confidential
     Information, including all photocopies, extracts and summaries thereof, and
     any such information stored electronically on tapes, computer disks or in
     any other manner, to the Company at any time upon request by the Company
     and upon the termination of his employment for any reason.

     (d) Executive shall not, so long as he is employed by the Company, engage
     in "Competition" with the Company. For purposes of this Agreement,
     Competition by Executive shall mean Executive's engaging in, or otherwise
     directly or indirectly being employed by or acting as a consultant or
     lender to, or being a director, officer, employee, principal, agent,
     stockholder, member, owner or partner of, or permitting his name to be used
     in connection with the activities of any other business or organization
     anywhere in the United States which competes, directly or indirectly, with
     the business of the Company as the same shall be constituted at any time
     during his employment hereunder.


     (e) For a period of six (6) months following the termination of Executive's
     employment hereunder, Executive shall not, directly or indirectly, engage
     in Competition with the Company in any locality or region of the United
     States in which the Company had operations at the time of, or within six
     (6) months prior to, such termination, or in which, during the six (6)
     month period prior to such termination, the Company had made substantial
     plans with the intention of establishing operations in such locality or
     region; provided , that it shall not be violation of this subparagraph for
     Executive to become the registered or beneficial owner of up to five
     percent (5%) of any class of the capital stock of a competing corporation
     registered under the Securities Exchange Act of 1934, as amended, provided
     that Executive does not actively participate in the business of such
     corporation until such time as this covenant expires.

     (f) For a period of twelve (12) months following the termination of
     Executive's employment hereunder, Executive shall not, directly or
     indirectly, for his benefit or for the benefit of any other person, firm or
     entity, do any of the following:

            (i) solicit from any customer doing business with the Company, as of
     Executive's termination of employment hereunder, business of the same or of
     a similar nature to the business of the Company, it being understood,
     however, that since customers in the Business often utilize more than one
     company at the same time to provide such services, then, to the extent any
     customer of the Company, as of Executive's termination, was also at the
     time a customer of another company, the restriction under this Section 7(f)
     (i) shall only apply to any increase in the amount of services to that
     customer attributable, directly or indirectly, to Executive which exceeds
     increases in the ordinary course of business;

            (ii) solicit from any known potential customer of the Company
     business of the same or of a similar nature to that which has been the
     subject of a known written or oral bid, offer or proposal by the Company,
     or of substantial preparation with a view to making such a bid, proposal or
     offer, within six (6) months prior to Executive's termination of employment
     hereunder;

            (iii) solicit the employment or services of, or hire, any person who
     was known to be employed by or was a known consultant to the Company upon
     Executive's termination of employment hereunder or within six (6) months
     prior thereto; or

            (iv) otherwise interfere with the business or accounts of the
     Company.

     (g) Executive acknowledges that the services to be rendered by him to the
     Company are of a special and unique character, which gives this Agreement a
     peculiar value to the Company, the loss of which may not be reasonably or
     adequately compensated for by damages in an action at law, and that a
     material breach or threatened breach by him of any of the provisions
     contained in this Section 7 will cause the Company irreparable injury.
     Executive therefore agrees that the Company shall be entitled, in addition
     to any other right or remedy, to a temporary, preliminary and permanent
     injunction, without the necessity of proving the inadequacy of monetary
     damages or the posting of any bond or security, enjoining or restraining
     Executive from any such violation or threatened violation.

     (h) Executive further acknowledges and agrees that due to the uniqueness of
     his services and confidential nature of the information he possesses, the
     convenants set forth herein are reasonable and necessary for the protection
     of the business and goodwill of the Company.



 8.   Termination.

     (a) Notwithstanding any provision of this Agreement to the contrary, the
     employment of Executive hereunder shall terminate on the first to occur of
     the following dates:

            (i)   the date of Executive's death or adjudicated incompetency;

            (ii) the date on which the Company shall give Executive notice of
     termination on account of Disability (as hereinafter defined);

            (iii) the date on which the Company shall give Executive notice of
     termination for Cause (as hereinafter defined);

            (iv) the date on which the Company shall give Executive (or his
     representative) notice of termination for any reason other than the reasons
     set forth in (i) through (iii), above, in which event Executive shall be
     entitled to receive, as his sole and exclusive remedy, a severance payment
     of twelve (12) months' salary (paid through the severance payment period),
     continuation of medical benefits coverage for Executive and any covered
     dependents during such twelve (12) month severance payment period plus pay
     for any unused vacation; provided, that if the Company gives notice of
     termination pursuant to this Section 8(a)(iv) within 12 months of a
     Change-of-Control Event (as hereinafter defined), Executive shall be
     entitled to continue to receive the severance payment and benefits provided
     in this Section 8(a)(iv) for an additional period of twelve (12) months
     from and after such Event, for an aggregate severance payment period
     consisting of the time prior to such Event plus twelve (12) months.

     (b) The Company shall be entitled at any time, upon notice to Executive, to
     terminate his employment hereunder on account of the Disability of
     Executive or for Cause, and, in either of such events, or in the event that
     Executive's employment hereunder shall terminate on account of the death,
     or adjudicated incompetency of Executive, Executive or his estate,
     conservator or designated beneficiary, as the case may be, shall be
     entitled to payment of any earned but unpaid salary and payment for unused
     vacation days, through the date of termination. Following any such
     termination, neither Executive nor his estate, conservator or designated
     beneficiary shall be entitled to receive any salary or other payment
     provided for hereunder with respect to any period after such termination.

     (c) For purposes of this Agreement, "Disability" shall mean an illness,
     injury or other incapacitating condition as a result of which Executive is
     unable to perform the services required to be performed under this
     Agreement for (i) ninety (90) consecutive days during the Term, or (ii) a
     period or periods aggregating more than one hundred twenty (120) days in
     any twelve (12) consecutive months. In any such event, the Company, in its
     sole discretion, may terminate this Agreement by giving notice to Executive
     of termination for Disability. Executive agrees to submit to such medical
     examinations as may be necessary to determine whether a Disability exists,
     pursuant to such reasonable requests made by the Company from time to time.
     Any termination of Executive's employment under this subparagraph shall not
     preclude Executive from obtaining the benefits provided under any short or
     long term disability income program or policy maintained by the Company,
     which benefits shall be provided solely in accordance with the terms of
     such program or policy, as amended from time to time by the Company.


     (d) For purposes of this Agreement, "Cause" shall mean the occurrence of
     any of the following, as reasonably determined by the Company:

            (i) the willful failure, neglect or refusal by Executive to
     substantially perform his duties hereunder (including, without limitation,
     Executive's inability to perform such duties as a result of alcohol or drug
     abuse, chronic alcoholism or drug addition), after a written demand for
     such substantial performance is delivered to Executive by the CEO
     specifying the manner in which the CEO believes Executive has not so
     substantially performed;

            (ii) any willful, intentional or grossly negligent act by Executive
     having the effect of materially injuring the business or reputation of the
     Company, or any of its parents, subsidiaries or affiliates;

            (iii) willful misconduct by Executive, including insubordination, in
     respect of the duties or obligation s of Executive under this Agreement;

            (iv) Executive's commission of a felony or misdemeanor involving
     moral turpitude (including entry of a nolo contendere plea);

            (v) any misappropriation or embezzlement of the property of the
     Company and its parents, subsidiaries and affiliates (whether or not a
     misdemeanor or felony); and

            (vi) a breach of any one or more of the convenants of this Agreement
     by Executive.

     Notwithstanding the foregoing, executive shall not be deemed to have been
     terminated for Cause unless and until (i) the CEO shall have delivered to
     Executive a preliminary notice of termination specifying the basis for such
     termination and given Executive and his counsel an opportunity, upon
     reasonable notice, to be heard by the Board of Directors of the Company,
     and (ii) following such hearing, the Board shall have determined that such
     termination was appropriate and so specified in a final notice to the
     effect and setting forth the effective date of such termination which shall
     be no earlier than the date of such final notice.

     (e) For purposes of this Agreement, "Good Reason" shall mean the occurrence
     of any of the following, as reasonably determined by Executive:

            (i) assignment to Executive of any duties materially and adversely
     inconsistent with his position or responsibilities as specified in Section
     1 hereof, or any other action by the Company which results in a material
     and adverse changes in such position or responsibilities;

            (ii) the failure of the Company to assign this Agreement to a
     successor to the Company;


            (iii) any failure by the Company to comply with the provisions of
     this Agreement;

            (iv) The Company's requiring Executive to have as his principal
     place of employment any office or location more than 50 miles from New York
     City, New York; or

            (v) any material adverse change to the terms and conditions of
     Executive's employment under this Agreement.

     Notwithstanding the foregoing, no event(s) shall constitute Good Reason
     hereunder if after a notice of termination for Good Reason is given to the
     Company by Executive, the Company with reasonable promptness cures or
     otherwise corrects the event or events claimed to provide the basis for
     such a termination and, in such case, such notice shall be deemed not to
     have been delivered.

     (f) If Executive shall be entitled to the additional 12 months of severance
     benefits set forth in the proviso to Section 8(a)(v) hereof, following a
     Change-of-Control Event, the restrictive period following termination of
     employment referred to in the first sentence of Section 7(f) hereof shall
     be deemed to continue for such additional 12 month severance payment
     period.

     (g) For purposes of this Agreement, "Change-of-Control" shall mean the
     consummation of (i) a proxy contest for control of the Company's Board of
     Directors resulting in the person or entity or group of affiliated persons
     or entities (collectively, a "Control Group") initiating such proxy contest
     electing a majority of the members of the Board of Directors of the
     Company; or (ii) the purchase by a Control Group of the common stock or
     other securities of the Company which, when aggregated with any other
     securities of the Company then held by such Control Group, gives such
     Control Group "beneficial ownership" (as defined in Rule 13d-3 under the
     Securities Exchange Act of 1934, as amended) of securities representing
     more than 50% of the combined voting power of the Company; or (iii) any
     such transaction which the Board of Directors of the Company shall have
     favorably recommended to shareholders of the Company at any time prior to
     its consummation (and such recommendation shall not have been withdrawn).

 9.  Return of Company Property. Executive agrees that following the termination
     of his employment hereunder for any reason, he shall return all property of
     the  Company,  or its  subsidiaries  and  affiliates,  which  is then in or
     thereafter  comes  into his  possession,  including,  but not  limited  to,
     documents,   contracts,   agreements,  plans,  photographs,  books,  notes,
     electronically  stored data and all copies of the  foregoing as well as any
     automobile  or other  materials  or  equipment  supplied  by the Company to
     Executive.

 10. Compensation in Event of Termination; Survival. Upon termination of
     Executive's employment hereunder for any reason, this Agreement shall
     terminate and the Company shall have no further obligation to Executive
     except to the extent Executive is otherwise entitled to any unpaid salary
     or benefits hereunder, insurance coverage in accordance with applicable
     law, and severance pay as provided herein; provided, that the provisions
     set forth in Sections 7, 8 and 9 hereof shall remain in full force and
     effect after the termination of Executive's employment, notwithstanding the
     expiration or termination of this Agreement.


 11. Entire Agreement. This Agreement sets forth the entire agreement between
     the parties with respect to its subject matter and merges and supersedes
     all prior discussions, agreements and understandings of every kind and
     nature between them and neither party shall be bound by any term or
     condition other than as expressly set forth or provided for in this
     Agreement. This Agreement may not be changed or modified except by an
     agreement in writing, signed by the parties hereto.

 12. Waiver. The failure of either party to this Agreement to enforce any of its
     terms, provisions or convenants shall not be construed as a waiver of the
     same or of the right of such party to enforce the same. Waiver by either
     party hereto of any breach or default by the other party of any term or
     provision of this Agreement shall not operate as a waiver of any other
     breach or default.

 13. Severability. In the event that any one or more of the provisions of this
     Agreement shall be held to be invalid, illegal or unenforceable, the
     validity, legality and enforceability of the remainder of the Agreement
     shall not in any way be affected or impaired therby. Moreover, if any one
     or more of the provisions contained in this Agreement shall be held to be
     excessively broad as to duration, activity or subject, such provisions
     shall be construed by limiting and reducing them so as to be enforceable to
     the maximum extent allowed by applicable law.

     to have been given when delivered by messenger or courier service (against
