Merger and without any action on the part of King Acquisition, the Company or
the holders of any of the following securities, the following securities will be
converted in the manner set forth below:

              (a)       Each share of Company Common which is issued and
                        outstanding immediately prior to the Effective Time
                        (other than treasury shares) shall be canceled and
                        extinguished and converted into and become a right to
                        receive (x) 225 shares of SAI Preferred (having in the
                        aggregate a $22.5 million liquidation value and
                        convertible into 4.5 million shares of SAI Common in the
                        aggregate), and (y) and $25,000 ($5 million in the
                        aggregate); provided, however, that if as the result of
                        the conversion of any Shareholder's Company Common upon
                        consummation of the Merger, a fractional interest in a
                        share of SAI Preferred would be deliverable under this
                        Section 2.6.(a), in lieu of a fractional share being
                        delivered therefor, such fractional interest shall
                        automatically be converted into the right to receive an
                        amount in cash (without interest) equal to the product
                        of the average of the high and low sale prices of the
                        SAI Common as reported by the AMEX on the trading day
                        immediately prior to the Effective Time, multiplied by
                        the number of shares of SAI Common into which such
                        fractional interest would be convertible. No such holder
                        will be entitled to dividends, voting rights or any
                        other rights as a shareholder in respect of any
                        fractional share.

              (b)       The SV Option shall be canceled and extinguished and
                        converted and become a right to receive 300,000 shares
                        of SAI Common in the aggregate.

              (c)       To the extent that actual RMR is less than the Minimum
                        RMR, then the number of shares of SAI Preferred, SAI
                        Common, and cash to be exchanged pursuant to this
                        Section 2.6 shall be proportionately reduced.

              (d)       Each share of Acquisition Common issued and outstanding
                        immediately prior to the Effective Time shall be
                        converted into one validly issued, fully paid and
                        nonassessable share of Company Common.

Effective Time the stock transfer books of the Company shall be closed and no

presented in accordance with this Agreement to the Surviving Corporation shall
be exchanged as provided in Section 2.8.

         2.8   Exchange of Common Certificates. Each holder of a certificate or
certificates representing shares of Company Common issued and outstanding
immediately prior to the Effective Time shall at or as soon as practicable
following the Closing, surrender to SAI for exchange a certificate or
certificates, duly endorsed in blank or accompanied by duly executed stock
powers, representing the number of shares of Company Common held by such holder.
In exchange therefor, SAI shall (x) issue to such holder of Company Common a
certificate or certificates representing the number of shares of SAI Preferred
to be issued to such holder pursuant to Section 2.6(a), and (y) the amount of
cash, if any, to be paid to be paid to such holder pursuant to Sections 2.6(a).
Surrendered certificates shall forthwith be canceled. At Closing,
SecurityVillage will surrender the original SV Option to SAI in exchange for the
SAI Common called for by Section 2.6(b). Until so surrendered and exchanged,
each such certificate (or the SV Option, as applicable) shall represent solely
the right to receive the consideration therefor provided in Sections 2.6(a) and
2.6(b), without interest, and SAI shall not be required to issue to such holder
the stock to which such holder otherwise would be entitled; provided, that
procedures allowing for payment against receipt of customary and appropriate
certifications and indemnities shall be provided with respect to lost or
destroyed certificates.

         2.9  Rights of the Company Shareholders. From and after the Effective
Time, the holders of shares of Company Common issued and outstanding at the
Effective Time shall have no rights with respect to such shares other than to
surrender the certificate or certificates representing such shares pursuant to
Section 2.8.

         2.10  Taking of Necessary Action; Further Action. SAI and King
Acquisition, on the one hand, and the Company and the Selling Shareholders, on
the other hand, shall use reasonable efforts to take all such action (including
action to cause the satisfaction of the conditions to the Merger) as may be
necessary or appropriate in order to effectuate the Merger as promptly as
possible. If, at any time after the Effective Time, any further action is
necessary or desirable to vest the Surviving Corporation with full possession of
all the rights, privileges, immunities and franchises of the Company and
Acquisition, the officers of the Surviving Corporation are fully authorized in
the name of either the Company or Acquisition or otherwise to take, and shall
take, all such action.

to or bound by any agreement or any judgment, order, writ, prohibition,
injunction or decree of any court or other governmental body which would prevent

Selling Shareholder's approval of the Merger or the conversion of such

                    Company nor any of its Subsidiaries has taken any action
                    which would, or failed to take any action which failure
                    would, in any way preclude or prevent the Company or any
                    such Subsidiary from continuing to operate the Monitoring
                    Business or any other business conducted by the Company or

                    respective shareholders are aware of any fact which could
                    lead to the revocation or suspension of any of such Dealer's

         3.18  Schedule 3.18 consists of the following:

               (a)  Schedule 3.18(a) is a true, accurate and complete list of

                    of April 30, 2000 (i) the RMR due from each Dealer under
                    each such agreement; (ii) the agings of the accounts

                    evidenced by written contracts, except those oral agreements

                    transactions in the normal course of business and such
                    agreements are valid and binding obligations of the Dealers
                    and Subscribers that are parties thereto without any
                    counterclaims, set-offs or other defenses thereto, and
                    neither the Company, its Subsidiaries or any selling
                    Shareholder has any basis to believe that the amounts
                    payable under such Accounts and Dealer Monitoring Agreements
                    are not collectible. Neither the Company nor any of its
                    Subsidiaries has any basis to believe that any Account or
                    Dealer Monitoring Agreement will not continue in existence
                    after the Closing.

         3.19  Litigation, etc. There are no actions, suits, proceedings or
investigations pending or threatened against the Company, its Subsidiaries or
their respective properties before any court, arbitration panel or governmental
agency (nor, to the Selling Shareholder's or the Company's Knowledge, is there
any reasonable basis therefor), nor is there any judgment, decree, injunction,
rule or order of any court, governmental department, commission, agency,
instrumentality or arbitrator outstanding against the Company, its Subsidiaries
or their respective assets or the Monitoring Business or any other business
conducted by the Company and its Subsidiaries, except as described on Schedule
3.19. Schedule 3.19 also contains a true and complete list of every incident for
the last five years in which a Subscriber or third party asserted that it
experienced a loss related to any failure or omission of the Company, its
Subsidiaries (other than Monital except to the extent disclosed in the Monital
Acquisition) or their provision of Monitoring Services, a short description of
the claim and its current status or resolution.

 3.20 Related Party Transactions. Except as disclosed on Schedule 3.20,
neither the Company, its Subsidiaries nor any shareholder, officer, director,
employee of the Company, its Subsidiaries, or any member of their immediate
families, is, directly or indirectly, interested in any contract with the
Company or its Subsidiaries, including but not limited to any agreement, written
or unwritten, for employment or consulting, or any lease for real or personal
property. No officer or employee of the Company or its Subsidiaries is a party
to or bound by any agreement, contract or commitment, or subject to any
restrictions (including confidentiality or non-compete restrictions) in
connection with any previous or current employment of any such person, which
adversely affects, or in the future may adversely affect, the business of the
Company or any of its Subsidiaries. Neither the Company nor any of its
Subsidiaries is a guarantor or indemnitor of any indebtedness of any other
Person, except as disclosed on Schedule 3.20. All existing agreements between
each Shareholder and the Company or its Subsidiaries have been (or on or prior
to the Closing will be) terminated and, thereafter, except as contemplated
herein, such Shareholder will not be a party to, subject to or bound by any
agreement, commitment or understanding whatsoever between such Shareholder and
the Company.

 3.21  Securities Law Compliance.

       (a) Each of the Selling Shareholders understands and agrees that: (i) the
           SAI Preferred to be issued pursuant to the Merger has not been, and
           as of the Effective Time will not be, registered under the Securities
           Act or under any state securities laws; (ii) the SAI Preferred is
           being offered and issued in reliance upon Federal and state
           exemptions for transactions not involving any public offering; (iii)
           a "stop transfer" order will be placed against the certificates
           representing shares of SAI Preferred issued pursuant to the Merger
           until such time as (A) such SAI Preferred is registered under the
           Securities Act or (B) until SAI has received an opinion of counsel
           satisfactory to it that a proposed transfer or sale does not require
           registration or qualification under applicable law; and (iv) until
           removed in accordance with Section 5.17, the certificates
           representing the shares of SAI Preferred and SAI Common issued in the
           Merger will bear the legend set forth below:

              The shares evidenced by this certificate have not been registered
              under the Securities Act of 1933, as amended (the "Act"), or any
              applicable state securities laws, in reliance on exemptions under
              the Act and applicable state securities laws. No transfer or sale
              of these shares or any interest therein may be made without such
              registration and qualification unless the issuer has received an
              opinion of counsel satisfactory to it that a proposed
<PAGE>   28


                transfer or sale does not require registration or qualification
                under applicable law.
     (b)    The Selling Shareholders each further represent that: (i) he is
            acquiring the SAI Preferred to be acquired him pursuant to the
            Merger solely for his own account for investment purposes and not
            with a view to the distribution thereof within the meaning of the
            Securities Act; (ii) he is a sophisticated investor with knowledge
            and experience in business and financial matters and is an
            "accredited investor" within the meaning of Rule 501 under the
            Securities Act; (iii) he has had access to all SAI SEC Reports filed
            by SAI during the current year and the year preceding the current
            year, and has had the opportunity to obtain additional information
            and ask questions and receive answers as desired in order to
            evaluate the merits and risks inherent in holding the SAI Preferred;
            (iv) he has not been offered the SAI Preferred by any form of
            general advertising or general solicitation; and (v) he is able to
            bear the economic risk and lack of liquidity inherent in holding the
            SAI Preferred.

  3.22 Brokers or Finders. Neither the Company, its Subsidiaries nor any
Shareholder has dealt with any broker or finder, and have not incurred, and will
not incur, directly or indirectly, as a result of any action taken by the
Company, its Subsidiaries or any Selling Shareholder, any liability for
brokerage or finders' fees or agents' commissions or any similar charges in
connection with the transactions contemplated by this Agreement.

  3.23 Tax Matters. The Company and each of its Subsidiaries: (i) has timely
filed all income, sales and employment tax returns that are required to have
been filed with all appropriate federal, state, county and local governmental
agencies that relate to the Company or its Subsidiaries or with respect to which
the Company or any of its Subsidiaries is liable or otherwise in any way
subject, including without limitation all tax returns due for the period ending
December 31, 1999, (and all such returns fairly reflect the operations of the
Company and its Subsidiaries for tax purposes), and all taxes, fees, assessments
and governmental charges of any nature ("Taxes") shown by such returns to be due
and payable have been paid, except for those amounts set forth on Schedule 3.23
as being contested in good faith and for which appropriate amounts have been
reserved and are reflected on the Company's Financial Statements, and will be
reflected on the Escrow Date Balance Sheet or the Closing Date Balance Sheet, as
the case may be, in accordance with GAAP; (ii) has timely paid all Taxes owed by
it or which it is obligated to withhold from amounts owing to any employee
(including without limitation social security taxes), creditor or third party
and (iii) has not waived any statute of limitations with respect to taxes or
agreed to any extension of time with respect to a tax assessment or deficiency.
The assessment of any additional Taxes for periods for which returns have been
filed will not exceed the liability therefor appearing on the Escrow Date
Balance

<PAGE>   29



Sheet or the Closing Date Balance Sheet, as the case may be, and there are no
material unresolved questions or claims concerning the tax liability of the
Company, its Subsidiaries. The tax returns of the Company and its Subsidiaries
have not been reviewed or audited by any federal, state, local or county taxing
authority. There is no pending dispute with any taxing authority relating to any
of said tax returns. The Company's Financial Statements do, and the Escrow Date
Balance Sheet and the Closing Date Balance Sheet will, accurately reflect all of
the tax liability of the Company and its Subsidiaries for Taxes as of their
respective dates. All of the income, sales and employment-related tax returns of
the Company and its Subsidiaries for the years 1997, 1998 and 1999 are attached
to Schedule 3.23. The books of the Company and its Subsidiaries will be closed
as of the Closing Date in order to properly determine the Taxes due for the
period ending on the Closing Date. The Selling Shareholders will fully cooperate
with the Company and its Subsidiaries in preparing their respective tax returns,
including, but not limited to, those for the stub period ending on the Closing
Date (the "Stub Period"). Neither the Company nor the Selling Shareholders have
taken or failed to take, or prior to the Closing will take or fail to take, any
action which would result in the loss of the Company's status as a Subchapter S
corporation or which would otherwise affect the Company's status as a Subchapter
S Corporation prior to Closing.

  3.24 Insurance. The Company and each of its Subsidiaries has valid workers'
compensation, fire, casualty, liability and errors and omissions policies, in
such amounts and with such coverage as is reasonably related to the foreseeable
risks of the Company and its Subsidiaries, in each case with reputable insurers.
The Company has provided to SAI true, accurate and complete copies of all such
policies. All of the fire, casualty, liability and errors and omissions policies
of the Company and its Subsidiaries are "occurrence" policies not "claims made"
policies. Neither the Company nor any of its Subsidiaries (a) is in default with
respect to any provision contained in any such policy, or (b) has failed to give
any notice or present any claim under any such policy in due and timely fashion.
Neither the Company nor any of its Subsidiaries will be placed in default, nor
will their coverage be canceled, as a result of the transactions contemplated by
this Agreement. There are no outstanding unpaid claims under any such policy.
Neither the Company nor any of its Subsidiaries has received notice of, nor have
they Knowledge of, any inaccuracy in any application for such policies, any
failure to pay premiums when due or any similar state of facts that might form
the basis for termination of any such insurance or rejection of any claim.
Within three years prior to the Closing Date, neither the Company nor any of its
Subsidiaries has canceled or terminated any insurance policy, nor has any
insurance company canceled or terminated any insurance policy of the Company or
its Subsidiaries or rejected any claim under such policy. All such policies will
remain in full force and effect following the Closing. Following the Closing,
the Company and its Subsidiaries will be able to cancel all such policies upon
no more than thirty (30) days written notice without payment of any additional
premium or any penalty.

other than those identified on Schedule 3.25. The Company has provided SAI with

              Benefit Plan that is intended to be qualified under Section 401(a)
              of the Code has been determined by the Internal Revenue Service to
              be so qualified, and each trust related to such plan has been
              determined to be exempt under Section 501(a) of the Code. No
              material liability has been incurred by the Company or any ERISA

              Affiliate failed to make any contributions or to pay and amounts
              due and owing as required by Section 412 of the Code, Section 302
              of ERISA or the terms of any Pension Plan prior to the due dates
              of such contributions under Section 412 of the Code or Section 302
              of ERISA, nor has there been any event requiring any disclosure

        (c)   Prohibited Transactions and Payments. Neither the Company nor any
              ERISA Affiliate has (i) engaged in a non-exempt "prohibited

        (a)   Directors, Officers and Employees. Schedule 3.26 sets forth the
              names of each director, officer and employee of the Company and
              each of its Subsidiaries and states the rate of compensation
              payable to each. Attached to Schedule 3.26 are copies of each
              written employment agreement and noncompetition agreement with any
              of such directors, officers and employees. Except as set forth in
              Schedule 3.26, no such agreement shall cause the Company or its
              Subsidiaries to make additional payments as a result of the
              Merger.

        (b)   Labor Matters. Neither the Company nor any of its Subsidiaries has
              been, or is, a party to any collective bargaining agreement with
              any union representing any of its employees. The Company and each

              applicable laws, rules and regulations relating to employment and
              employment practices, immigration laws, terms and conditions of
              employment, wages and hours. None of the employees of the Company
              or its Subsidiaries is represented by a labor union. There has not
              been, and there are not presently, pending or threatened any
              unfair labor practice or discrimination charges or complaints
              against the Company or its Subsidiaries before the National Labor
              Relations Board, the Equal Employment Opportunity Commission or

        (c)   Continued Service by Certain Employees. Mr. Thomas J. Few Sr. has
              agreed, without additional consideration, to remain employed by

              in full compliance with, and have not been and are not in
              violation of or liable under, any Environmental Law. None of the

              pursuant to any Environmental Law, with respect to or affecting
              any of the Facilities or any other properties and assets (whether

              or potential violation or failure to comply with any Environmental
              Law, or of any alleged, actual, or potential obligation to

received from the Company, of any misstatements or omissions in the Company's
disclosure schedules, use its best efforts to inform the Company of such

<PAGE>   39

              of its Subsidiaries is a party or by which it is bound, which

              or other business conducted by the Company or its Subsidiaries or

SAI, and that he will not, directly or indirectly:

          (a) enter into competition with the Company or SAI, or their
              respective Subsidiaries, by establishing a remote alarm system
              monitoring center providing monitoring services to any location
              within twenty five (25) miles of any location where the Company,
              SAI or their respective Subsidiaries provide such services;

          (b) provide, or solicit any Dealer or Subscriber for the purposes of

              terminate his or her employment with any of the foregoing (other
              than employees who have worked primarily for the Transferred
              Business Units and who accept employment with Morlyn on or prior
              to Closing), at any time within one year after such employee's
              termination of employment with the Company or SAI; or

          (e) for so long as the Company and its Subsidiaries are engaged in the
              Monitoring Business and its other businesses, take any other
              action which is intended to, or which would reasonably be expected
              to:

              (i)    adversely affect the Company's, SAI's or their respective
                     Subsidiaries' interest in any Contract;

              (ii)   adversely affect the Company's, SAI's or their respective
                     Subsidiaries' contractual relationship with any Dealer or
                     Subscriber; or

              (iii)  discourage any Dealer, Subscriber or supplier from
                     continuing its business relationship with the Company, SAI

                     same terms as were maintained prior to the Closing.
<PAGE>   41


     For purposes of this Section 5.9, the term "Selling Shareholder" shall also
include any corporation, partnership or other business entity in which a Selling
Shareholder now or in the future owns, directly or indirectly, a controlling
equity interest, and the parents, spouse, or children, of a Selling Shareholder,
or any entity in which any of them own, directly or indirectly, a controlling
interest. Notwithstanding any other provision of this Agreement, each Selling
Shareholder agrees that money damages would not be a sufficient remedy for
breach of this Section 5.9 and that SAI shall be entitled to specific
performance, injunctive relief or other equitable relief as a remedy for breach
of this Section 5.9; provided, however, that all such equitable remedies would
be in addition to all remedies available at law to SAI.
     5.10 Confidentiality. From the date hereof until the Closing, the Selling
Shareholders will, and will cause the Company and its Subsidiaries and their
respective officers, directors and employees to, treat as strictly confidential
all Confidential Information concerning SAI, the Company and their respective
Subsidiaries that is not part of the public domain and shall not disclose any
such information to any third party. At all times after the Closing each of the
Selling Shareholders will treat and hold as confidential all Confidential
Information concerning SAI, the Company and their respective Subsidiaries,
refrain from using any of such Confidential Information (except, as applicable,
in direct furtherance of such Shareholder's duties on behalf of SAI, the Company
or their respective Subsidiaries (as directed by SAI)) and shall deliver
promptly to the SAI or the Company or destroy, at the request and option of SAI,
all tangible embodiments (and all copies) of Confidential Information concerning
SAI, the Company or their respective Subsidiaries which are in such
Shareholder's possession. In the event that any of the Selling Shareholders is
requested or required (by oral question or written request for information or
documents in any legal proceeding, interrogatory, subpoena, civil investigative
demand, or similar process) to disclose any Confidential Information concerning
SAI, the Company or their respective Subsidiaries, such Shareholder will notify
SAI promptly of the request or requirement so that SAI may seek an appropriate
protective order or waive compliance with the provisions of this Section 5.10.
If, in the absence of a protective order or the receipt of a waiver hereunder,
any of the Selling Shareholders is, on the advice of counsel, compelled to
disclose any of such Confidential Information to any tribunal or else stand
liable for contempt, such Selling Shareholder may disclose such Confidential
Information to the tribunal; provided, however, that the disclosing Selling
Shareholder shall, upon the request of SAI or the Company and at their expense,
exert all reasonable efforts to obtain an order or other assurance that
confidential treatment will be accorded to such portion of the Company
Confidential Information required to be disclosed as the Company or SAI shall
reasonably designate.

     5.11 Tax Returns. The Selling Shareholders agree to cause the Company and
its Subsidiaries to file for all tax periods prior to the Closing Date, all
Federal, state, and local income, property, and payroll tax returns. The Selling
Shareholders hereby agree to indemnify SAI pursuant to Article 10 hereof for any
costs incurred for any unpaid tax liabilities related to the Company or its
Subsidiaries arising from any state of facts existing prior to the Closing Date,
including, but not limited to, Federal, state, and local


<PAGE>   42

income taxes. With regard to the partial tax year ended on the Closing Date (the
"Stub Period"), the Selling Shareholders shall cause the Company's final
Subchapter S return for such period to be prepared and filed. The Company will
cause its Subsidiaries to prepare and file in a timely manner their final tax
return(s) for the Stub Period consistent with the basis for preparation
previously disclosed by Weil Gotshall. The Company will make a distribution to
the Selling Shareholders in an amount equal to their Federal and state tax
liability arising from the inclusion of the Company's income on their personal
Federal and state tax returns for such period as reflected on such tax returns
or as certified to SAI by the accountant preparing such returns to the extent
not previously distributed by the Company. The Selling Shareholders will
indemnify the Company for any tax liability of the Company or its Subsidiaries
for the Stub Period in excess of the amount shown on the final tax returns of
the Company and its Subsidiaries for the Stub Period.

     5.12 Financial Statement Audits. If at any time SAI deems it necessary or
advisable to have an independent audit performed on the financial statements of
the Company or its Subsidiaries, (including, without limitation, in connection
with the Proxy Statement), the Selling Shareholders will fully cooperate with
SAI and the independent auditors in the performance of the audit. In furtherance
and not in limitation of the foregoing, the Selling Shareholders will cooperate
and provide all assistance reasonably requested by SAI's independent accountants
and the Company's independent accountants (including without limitation,
executing any and all customary management representation letters with respect
to the Company's financial statements) in connection with the preparation and
delivery to SAI of audited financial statements and for the Company as of and
for each of the fiscal years ended December 31, 2003.

     5.13 Disclosure to State Taxing Authorities. The Selling Shareholders shall
make all necessary disclosures related to the exchange of the Shares in
connection with the Merger as are required under the applicable state laws, and
no amounts are required to be withheld from consideration to be received by the
Selling Shareholders in connection with the Merger pursuant to such laws.

     5.14 Update Disclosure; Breaches. From and after the date of this Agreement
until the Closing, the Selling Shareholders shall promptly notify SAI, by
written update to the attachments hereto, of (i) the occurrence or
non-occurrence of any event which would be likely to cause any condition to its
obligations to effect the Merger and the other transactions contemplated by this
Agreement not to be satisfied, (ii) any fact, condition or occurrence which
would be likely to result in any of the representations or warranties of the
Selling Shareholders not being true and correct as of the Closing, or (iii) the
failure of the Selling Shareholders to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by the Company, its
Subsidiaries or the Selling Shareholders pursuant to this Agreement which would
be likely to result in any condition to the obligations of any Party to effect
the Merger and the other transactions contemplated by this Agreement not to be
satisfied. The delivery of any notice pursuant to this Section 5.14 shall not
cure any breach of any representation or



<PAGE>   43

warranty requiring disclosure of such matter prior to the date of this Agreement
or otherwise limit or affect the remedies available hereunder to SAI.

     5.15 Waiver and Release. Subject to, and conditioned upon, the consummation
of the Merger, each Selling Shareholder, on behalf of himself and his heirs,
executors, administrators, successors and assigns (with respect to each Selling
Shareholder, the "Selling Shareholder Releasing Parties"), irrevocably and
unconditionally waives and releases any and all rights with respect to, and
releases, forever acquits and discharges each of the Company and its
Subsidiaries and their officers, employees, agents and other representatives,
and their respective heirs, executors, administrators, successors and assigns
(the "Company Released Parties"), with respect to, each and all claims, demands,
charges, complaints, obligations, causes of action, suits, liabilities,
indebtedness, sums of money, covenants, agreements, instruments, contracts
(written or oral, express or implied), controversies, promises, fees, expenses
(including attorneys' fees, costs and expenses), damages and judgments, at law
or in equity, in contract or tort, in federal, state or other judicial,
administrative, arbitration or other proceedings, of any nature whatsoever,
known or unknown, suspected or unsuspected, previously, now or hereafter
arising, in each case which arise out of, are based upon or are connected with
facts or events occurring or in existence on or prior to the Effective Time (the
"Company Released Claims"). Each Selling Shareholder further represents and
warrants that such Shareholder has not assigned or otherwise transferred any
right or interest in or to any of the Released Claims. This Section 5.15 shall
not apply to any of the following: (a) claims for salaries and benefits accrued
through the Closing under the express terms of the written benefit plans of the
Company or its Subsidiaries, or (b) claims for indemnification pursuant to
Section 10.1(b) herein.

     5.16 Verbal Dealer Monitoring Arrangements. The Company and the Selling
Shareholders shall use their best efforts to replace all verbal Dealer or
Subscriber monitoring arrangements with written agreements reflecting such
arrangements prior to Closing.

     5.17 Post-Closing Transfer of SAI Securities.

          (a) The Selling Shareholders hereby acknowledge and agree that the SAI
              Preferred or the SAI Common issued in connection with the Merger
              may not be transferred except pursuant to (a) a registered
              offering under the Securities Act (in which case all transfers
              shall be made in accordance with all applicable provisions of the
              Registration Agreement), (b) Rule 144 promulgated pursuant to the
              Securities Act (or any similar rule or rules then in force) if
              available, or (c) subject to the conditions specified in
              subparagraph (b) below, any other legally available means of
              transfer.

          (b) In connection with the transfer of any SAI Preferred or SAI Common
              issued in connection with the Merger (other than a

<PAGE>   44

                 transfer pursuant to a registered public offering), the holder
                 thereof shall deliver written notice to SAI describing in
                 reasonable detail the transfer or proposed transfer, together
                 with an opinion of securities counsel (with such opinion and
                 such counsel being satisfactory to SAI) to the effect that such
                 transfer of SAI Preferred or SAI Common may be effected without
                 registration of such SAI Preferred or SAI Common under the
                 Securities Act or any applicable state securities law. In
                 addition, if the holder of SAI Preferred delivers to SAI such
                 an opinion that concludes that no subsequent transfer of such
                 SAI Preferred or SAI Common will require registration under the
                 Securities Act or any applicable state securities law, SAI
                 shall promptly upon such contemplated transfer deliver new
                 certificates for such SAI Preferred or SAI Common which do not
                 bear the restrictive legend set forth in Section 3.21(a). If
                 SAI is not required to deliver new certificates for such SAI
                 Preferred or SAI Common not bearing such legends, the holder
                 thereof shall not transfer the same until the prospective
                 transferee has confirmed to SAI in writing its agreement to be
                 bound by the conditions contained in this Section.

                                   ARTICLE 6

                                COVENANTS OF SAI
     6.1 Necessary Consents. Prior to the Closing, SAI will use its best efforts
obtain such consents and take such other actions as may be necessary or
appropriate to allow the consummation of the Merger and the other transactions

     6.2 Offer of Employment. SAI agrees that SAI, the Company or its
Subsidiaries will offer employment to each of the individuals listed on Schedule
6.2 at the annual salary rates set forth on Schedule 6.2. Each such employee
that accepts such an offer will be an employee at will.

     6.3 Confidentiality. SAI agrees to abide by the confidentiality provisions
of the Letter of Intent; provided, however, that SAI, as a reporting company
under the Securities Exchange Act and as an issuer of securities under the
Securities Act, may make all disclosures concerning this Agreement, the Selling
Shareholders and the Company and its Subsidiaries as are required by Federal and
state securities laws, as determined by SAI and its counsel.

     6.4 SAI Stockholders Meeting. SAI shall call a meeting of its stockholders
(the "SAI Stockholders Meeting"), to be held as promptly as practicable for the
purpose of voting, among other things, upon the Merger and the issuance of the
shares of SAI Preferred and SAI Common contemplated hereunder, SAI will, through
its Board of Directors recommend to its stockholders, as applicable, approval of
such matters and will

         (a) Subject to Section 10.1(d), the Selling Shareholders, jointly and
             severally, will indemnify and hold harmless SAI, its Subsidiaries
             and their respective successors, affiliates and assignees and their
             respective shareholders, officers, directors, employees and agents
             ("SAI Indemnified Parties") against any losses, claims, damages or
             liabilities, including, without limitation, reasonable attorneys'
             fees and other reasonable defense costs, in each case, to the
             extent not covered by insurance (hereafter "Losses"), to which any
             SAI Indemnified Party becomes subject in connection with the
             following; provided, however, that, in the event that the Merger is
             not consummated as provided herein, the Company and the Selling
             Shareholders, jointly and severally, shall be responsible for the
             indemnification obligations of the Selling Shareholders contained
             in Section 10.1(a); and provided further, that in the event that
             the Merger is not consummated as provided herein, the Selling
             Shareholders shall be responsible for the indemnification
             obligations contained in Section 101.(a) only if such Selling
             Shareholders caused the Company to take, or to fail to take, any
             action or failure to act giving rise to the claim for
             indemnification thereunder:

             (i)    finders' fees or brokerage commissions incurred or alleged
                    to have been incurred by the Selling Shareholders with
                    respect to the transactions contemplated by this Agreement;

             (ii)   any liability of the Company or its Subsidiaries not
                    disclosed in writing prior to the Escrow Closing (other than
                    liabilities of a similar type as those disclosed which arise
                    thereafter prior to the Closing in the ordinary course of
                    business to the extent expressly permitted by the terms of
                    this Agreement);

             (iii)  any misrepresentation of fact, or failure to disclose a
                    material fact, by the Selling Shareholders;

             (iv)   any breach of any representation or warranty by the Selling
                    Shareholders contained in this Agreement or in any document
                    delivered hereunder;

<PAGE>   55

             (v)    any claims which have been or may be in the future asserted
                    arising out of the provision of Monitoring Services (or
                    failure to adequately provide such services) or otherwise
                    arising out of the business conducted by the Company or its
                    Subsidiaries which occurred prior to the Closing;

             (vi)   any breach of any covenant or agreement by the Company or
                    the Selling Shareholders contained herein or in any document
                    delivered hereunder, to be performed prior to or after the
                    Closing;

             (vii)  the failure to obtain any Required Consent; or

             (viii) any other liability or expense resulting from a dispute or
                    cause of action relating to the business of the Company or
                    its Subsidiaries, arising from an event, act, or omission
                    occurring before the Closing or related to the enforcement
                    of the indemnification provisions of this Agreement.

     (b)  SAI will indemnify and hold harmless the Selling Shareholders, their
          heirs, successors, affiliates, assigns ("Selling Shareholder
          Indemnified Parties") against any Loss to which any Selling
          Shareholder Indemnified Party becomes subject in connection with:

             (i)   finders' fees or brokerage commissions incurred or alleged to
                   have been incurred by SAI with respect to the purchase
                   transaction;

             (ii)  any misrepresentation of fact, or failure to disclose a
                   material fact, by SAI;

             (iii) any breach of any representation or warranty by SAI
                   contained herein or in any document delivered hereunder;

             (iv)  any breach of any covenant or agreement by SAI contained
                   herein or in any document delivered hereunder, to be
                   performed prior to or after the Closing Date; or

             (v)   any liability or expense resulting from a dispute or cause of
                   action relating to the Company or its Subsidiaries, arising
                   from an event, act or omission occurring after the Closing.


<PAGE>   56

     (c)  Such indemnification shall include any and all actions, suits,
          proceedings, demands, assessments or judgments, costs and expenses
          incidental to any of the foregoing matters set forth in Section
          10.1(a) and 10.1(b) or enforcement of the indemnification provisions
          of this Agreement.

     (d)  The obligation of the Selling Shareholders to indemnify SAI under
          Section 10.1(a) shall be subject to the following:

          (i)  The Selling Shareholders will be obligated to indemnify SAI from
               and against any Losses (other than Losses under Section
               10.1(a)(vii)) only after SAI shall have suffered aggregate Losses
               in excess of $50,000, at which point the Selling Shareholders
               will be obligated to indemnify SAI from and against all Losses
               relating back to the first dollar; and

          (ii) The Selling Shareholders will be obligated to indemnify SAI from
               and against any Losses under Section 10.1(a)(vii) only after SAI
               shall have suffered aggregate Losses under such Section in excess
               of $50,000 (with respect to any particular Required Consent), or
               $150,000 (with respect to all Required Consents in the
               aggregate), at which point the Selling Shareholders will be
               obligated to indemnify SAI from and against all such Losses in
               excess of such amounts; and

         (iii) The Selling Shareholders shall be obligated to indemnify SAI
               from and against any Losses arising out of the breach of any of
               the representations and warranties made by the Selling
               Shareholders only to the extent that SAI makes a written claim
               within the applicable survival period (as specified in Section
               12.1) with respect to the breach which gives rise to such Losses.

     10.2 Indemnification Procedures. For the purposes of this Section 10.2, the
term "Indemnitee" shall refer to the person or persons entitled, or claiming to
be entitled, to be indemnified, pursuant to the provisions of Section 10.1. The
term "Indemnitor" shall refer to the person or persons having the obligation to
indemnify pursuant to such provisions.

          (a)  Notice. An Indemnitee shall promptly give the Indemnitor written
               notice of any matter which an Indemnitee has determined has given
               or could give rise to a right of indemnification under this
               Agreement, stating the amount of the Loss, if known, and method

<PAGE>   57

               of computation thereof, all with reasonable particularity and
               containing a reference to the provisions of this Agreement in
               respect of which such right of indemnification is claimed or
               arises. If an Indemnitee shall receive notice of any claim by a
               third party which is or may be subject to indemnification (a
               "Third Party Claim"), the Indemnitee shall give the Indemnitor
               prompt written notice of such Third Party Claim and shall permit
               the Indemnitor, at its option, to participate in the defense of
               such Third Party Claim by counsel of its own choice (subject to
               Indemnitee's approval, which shall not be unreasonably withheld)
               and at the Indemnitor's expense. If, however, the Indemnitor
               acknowledges in writing its obligation to indemnify the
               Indemnitee hereunder against all Losses that may result from such
               Third Party Claim (subject to the limitations set forth herein),
               then the Indemnitor shall be entitled, at its option, to assume
               and control the defense of such Third Party Claim at its expense
               and through counsel of its choice, provided however, that
               Indemnitee shall have the right to approve in its sole reasonable
               discretion the choice of counsel. In the event the Indemnitor
               exercises its right to undertake the defense of any such Third
               Party Claim, the Indemnitee shall co-operate with the Indemnitor
               in such defense and make available to the Indemnitor, at the
               Indemnitor's expense, all witnesses, pertinent records, materials
               and information in its possession or under its control relating
               thereto as is reasonably required by the Indemnitor. Similarly,
               in the event the Indemnitee is, directly or indirectly,
               conducting the defense against any such Third Party Claim, the
               Indemnitor shall co-operate with the Indemnitee in such defense
               and make available to it all such witnesses, records, materials
               and information in its possession or under its control relating
               thereto as is reasonably required by the Indemnitee. In the event
               that the Indemnitor fails to agree to undertake defense of the
               Third Party Claim within thirty (30) days of receipt of notice of
               such claim from the Indemnitee, the Indemnitee shall be entitled
               to undertake such defense with counsel of its own choice, and the
               Indemnitor shall promptly reimburse the Indemnitee for all
               expenses incurred. The Indemnitor without the written consent of
               the Indemnitee may settle no Third Party Claim, unless the
               settlement involves only the payment of money by the Indemnitor.
               Similarly, no Third Party Claim, which is being defended in good
               faith by the Indemnitor, shall be settled by the Indemnitee
               without the written consent of the Indemnitor.

          (b)  Calculation of Losses. Losses shall be determined after taking
               into account any insurance proceeds received by an Indemnitee or
               its

<PAGE>   58


               affiliates from a non-affiliated insurance company on account of
               such Losses (after taking into account any costs incurred in
               obtaining such proceeds and any increase, determined in the
               reasonable judgment of the Indemnitee and confirmed by the
               insurance company, in insurance premiums as a result of the claim
               for which such proceeds were paid). The Indemnitor shall not be
               liable for any increase in Losses sustained by the Indemnitee,
               resulting from Indemnitee's failure to give Indemnitor timely
               written notice of any matter likely to give rise to a right of
               Indemnification hereunder.

                                   TERMINATION

     11.1 Termination. This Agreement may be terminated at any time prior to the
Effective Time, by written notice by the terminating Party to the other Parties,
whether before or after approval of the matters presented in connection with the
Merger by the Selling Shareholders of the Company, as follows:

          (a)  by mutual written consent of SAI and the Company; or

          (b)  by either SAI or the Company, if the Merger shall not have been
               consummated by December 29, 2000 (provided, however, that the
               right to terminate this Agreement under this Section 11.1(b)
               shall not be available to any Party whose failure to fulfill any
               obligation under this Agreement has been the cause of or resulted
               in the failure of the Merger to occur on or before such date, and
               provided further, that this Agreement may be extended up to 45
               days by either Party by written notice to the other Party if the
               Merger would have been consummated but for the absence of one or
               more required Approvals or third-party consents, and such
               Approval (s) or consent(s) can reasonably be expected to be
               obtained within such 45 day period); or

          (c)  by either SAI or the Company if a court of competent jurisdiction
               or other governmental entity shall have issued a final order,
               decree or ruling, or taken any other action, having the effect of
               permanently restraining, enjoining or otherwise prohibiting the
               Merger, and all appeals with respect to such order or action have
               been exhausted or the time for appeal of such order, decree,
               ruling or action shall have expired;

          (d)  by SAI, if a material breach of any representation, warranty,
               covenant or agreement on the part of the Selling Shareholders set

<PAGE>   59

               forth in this Agreement shall have occurred which would cause the
               conditions set forth in Article 7 not to be satisfied, and, that
               with respect to any breach of a covenant or agreement hereunder,
               such covenant or agreement is incapable of being cured or, if
               capable of being cured, shall not have been cured within ten (10)
               business days following receipt by the Company of written notice
               of such breach from SAI;

          (e)  by the Company, if a material breach of any representation,
               warranty, covenant or agreement on the part of SAI set forth in
               this Agreement shall have occurred which would cause the
               conditions set forth in Article 8 not to be satisfied, and, with
               respect to any breach of a covenant or agreement hereunder, such
               covenant or agreement is incapable of being cured or, if capable
               of being cured, shall not have been cured within ten (10)
               business days following receipt by SAI of written notice of such
               breach from the Company; or

          (f)  by the Company, if the Proxy Statement has not been filed by SAI
               on or prior to September 1, 2000.

     11.2 Effect of Termination. In the event of termination of this Agreement
pursuant to Section 11.1, there shall be no Liability or obligation on the part
of SAI, the Company, or their respective officers, directors, shareholders or
affiliates, except as provided in Article 10, and further except for the
liability of any Party then in breach of any of its representations, warranties,
covenants or agreements in this Agreement; and provided, that the provisions of
Sections 5.9, 5.10 and 6.3, Article 10 and this Section 11.2 shall remain in
full force and effect and survive any termination of this Agreement.

party. The representations and warranties set forth in this Agreement shall
survive the Closing until the fourth anniversary of the Closing, except for
representations and warranties relating to taxes, title to stock and
environmental matters and claims of the nature covered by the insurance carried

the applicable statute of limitation of the particular matter, and except claims
