Ladies and Gentlemen:


     Reference is made to the letter dated April 21, 2000 among the parties
hereto (the "April 21 Letter"). The purpose of this letter is to memorialize our
agreement to make certain changes to the April 21 Letter as set forth below.
Unless otherwise indicated, all capitalized terms in this letter shall have the
meanings set forth in the April 21 Letter.

     1.   All references to May 2, 2000 in Sections 3(c) and 4(f) of the April
          21, 2000 Letter are hereby changed to May 22, 2000. All other dates in
          those sections shall remain unchanged.

     2.   SecurityVillage's due diligence investigation of SAI, and SAI's due
          diligence investigation of SecurityVillage, pursuant to Section 3(b)
          of the April 21 Letter are hereby extended until May 22, 2000. All
          other due diligence investigations referred to in Section 3(b) of the
          April 21 Letter shall be deemed to have been satisfactorily completed
          simultaneous with the consummation of the Monital Acquisition as
          provided in Section 1(b) of the April 21 Letter.

     3.   The terms and conditions of Exhibit C relating to SecurityVillage's
          rights with respect to the business of King shall apply from and after
          the date of this letter and serve as an interim agreement between the
          parties pending completion of a more formal Dealer Agreement pursuant
          to Section 4(f) of the April 21 Letter. In the event that the parties
          do not enter into such Dealer Agreement, the rights granted to
          SecurityVillage under Exhibit C shall nevertheless be a binding
          obligation of King for a term of six years following the date of this

          letter; provided, however, that King may terminate such rights upon
          written notice of termination to SecurityVillage if SecurityVillage
          materially breaches the April 21 Letter and fails to substantially
          cure such breach within (i) ten (10) days after receipt of written
          notice of breach from King in the case of monetary obligations, or
          (ii) thirty (30) days after receipt of written notice of breach from
          King in the case of non-monetary obligations.

     4.   King's right to exercise the put option feature of the King Option
          shall be subject to satisfaction of each of the following conditions:
          (i) if the Monital Acquisition has closed prior to exercise of such
          put option, the total RMR of King and its subsidiaries for the
          calendar month ending one month prior to the exercise of such put
          option shall be at least $1.3 million (the "Minimum King/Monital
          RMR"); (ii) if the Monital Acquisition has not closed prior to
          exercise of such put option, the total RMR of King and its
          subsidiaries for the calendar month ending one month prior to the
          exercise of such put option shall be at least $900,000 (the "Minimum
          King RMR"); and (iii) there has been no change to the business of King
          or its subsidiaries prior to the exercise of such put option that
          would materially impair King's ability to service the Minimum
          King/Monital RMR or Minimum King RMR (as applicable).


Except as set forth above, all of the terms and conditions of the April 21
Letter shall remain unchanged.
