                   ARTICLE 6 CERTAIN COVENANTS AND AGREEMENTS

Section 6.1 No Inconsistent Agreements

            Each of the Agreement Parties shall use its best efforts to ensure
that none of their respective Subsidiaries, Affiliates or shareholders enter
into any agreement or take any action with respect to the Transactions or any
other matter contemplated by this Agreement which is inconsistent with the
fulfillment of its obligations under this Agreement or which otherwise conflicts
with the provisions hereof.

Section 6.2 Fulfillment of Conditions

            Each of the Agreement Parties will proceed diligently to satisfy
each condition to the other's obligations contained in this Agreement and to
consummate the Transactions, and none will take or fail to take any action that
could be reasonably expected to result in the nonfulfillment of any such
condition or to cause any of the Transactions not to be consummated.

Section 6.3 Confidentiality



                                       10
<PAGE>   11

            Each Corporate Party will hold, and will use its best efforts to
cause its Affiliates, and their respective representatives to hold, in strict
confidence from any Person (other than an Affiliate or representative) all
documents and information concerning any other Corporate Party or its Affiliates
furnished to it by the other Corporate Party or its representatives in
connection with this Agreement or the transactions contemplated hereby. The
provisions of this Section shall not apply to the extent that such documents or
information can be shown to have been (a) previously known by the party
receiving it, (b) in the public domain through no fault of the receiving party
or (c) acquired by the receiving party from another source if the source is not
under an obligation to another Corporate Party to keep such documents and
information confidential. The foregoing shall not apply: (a) if a party is
compelled to disclose by judicial or administrative process or by other
requirements of law; (b) if confidential information is disclosed in an action
or proceeding brought by a Corporate Party in pursuit of its rights or in the
exercise of its remedies; or (c) to a Corporate Party's use of documents and
information concerning the other Corporate Party after acquiring another
Corporate Party. In the event the King Acquisition or the merger contemplated by
the Merger Agreement is not consummated, upon the request of a disclosing
Corporate Party, each other Corporate Party to the transaction that was not
consummated will, and will cause its Affiliates and their respective
representatives to, promptly return all copies of confidential documents and
information furnished by the disclosing Corporate Party and destroy all writings
containing confidential information.

Section 6.4 Approvals

            Subject to the exercise of fiduciary obligations under applicable
law as advised in writing by independent legal counsel, each Corporate Party
shall deliver resolutions of its board of directors approving all necessary
corporate actions required to fulfill such Corporate Party's obligations
pursuant to this Agreement. Each Corporate Party shall take all commercially
reasonable steps to obtain the adoption and approval of such corporate actions
by such Corporate Party's stockholders where necessary.

Section 6.5 Voting Agreement

            In the event that SAI in its sole discretion determines that a vote
of its stockholders is required to approve any or all of the transactions
contemplated hereby, each of the parties to this Agreement hereby agree to vote
all shares they control and are entitled to vote in favor of the transactions
contemplated hereby at any meeting of stockholders or written consent requested
by SAI. SecurityVillage agrees to promptly call a meeting of its stockholders to
approve the transactions contemplated hereby, and each of the SecurityVillage
Controlling Stockholders agree to vote all shares of SecurityVillage's voting
capital stock held or controlled by them, in favor of all of the transactions
contemplated hereby.

Section 6.6 SecurityVillage Designees

            Prior to the Investment Closing, SecurityVillage will deliver to SAI
a schedule that sets forth the SecurityVillage Designees who will acquire the
SAI Securities contemplated by Section 2.2 and Articles 3 and 4 hereof and
specifies, for each such SecurityVillage Designee, the SAI securities they will
receive. The SAI securities may initially be held by an escrow agent on behalf
of SecurityVillage and the SecurityVillage Designees.

Section 7.1 Entire Agreement; Mutual Release

            This Agreement and any other agreements executed in connection
herewith, including without limitation, Amended King Agreement, constitute the
entire agreement between the parties with respect to the subject matter hereof
and supersede all prior agreements and understandings between the parties with
respect to the subject matter hereof, including without limitation, the Letter
Agreement. Without limiting the generality of the foregoing, this Agreement
supersedes the Letter Agreement in its entirety and the Letter Agreement is
hereby terminated and shall be of no further force and effect. Each party hereto
releases and forever discharges each other party hereto and its respective
agents, servants, members, managers, employees, directors, officers, attorneys,
affiliates, subsidiaries, successors and assigns and all persons, firms,
corporations, and organizations acting on their behalf, from all damage, loss,
claims, demands, liabilities, obligations, actions and causes of action
whatsoever, known or unknown, liquidated or unliquidated, certain or contingent,
that such Party hereto has had, now has, may now have or claim to have, or may
hereafter have, against each and every other party hereto, on account of, in
connection with, or in any way touching, concerning, relating to, arising out of
or founded upon, the Letter Agreement and any of the transactions contemplated
thereby, whether oral or written, including all such loss or damage of any kind
heretofore sustained, or that may otherwise arise as a consequence of the
dealings between the Parties hereto up to and including the date of this
Agreement, other than the obligations of a party under the express terms of this
Agreement or any definitive agreement executed by such party pursuant to this
Agreement or pursuant to the Letter Agreement (collectively, the "RELEASED
CLAIMS"). Each party hereby represents and warrants to the other parties that
such party has not sold, assigned or transferred any Released Claims (in whole
or in part), agrees not to bring any action with respect to any of the Released
Claims and agrees that this Section 7.1 may be plead as a complete defense and
bar to any such action.

Section 7.2 No Assignment; Binding Effect

            Neither this Agreement nor any right, interest or obligation
hereunder may be assigned by any party hereto without the prior written consent
of the other parties hereto and any attempt to do so will be void. Subject to
the preceding sentence, this Agreement is binding upon, inures to the benefit of
and is enforceable by the parties hereto and their respective permitted
successors and assigns.

Section 7.3 Amendment; Waiver; Termination

            No provision of this Agreement may be waived except by an instrument
in writing executed by the party against whom the waiver is to be effective. No
provision of this Agreement may be amended or otherwise modified except in
writing executed by each of the Agreement Parties.

Section 7.4 Public Announcements

securities exchange or national market system, so long as this Agreement is in
effect, none of the

                                       12
<PAGE>   13

Agreement Parties will, or permit any of their representatives to, cause the
publication of any press release or other public announcement relating to the
Transactions without the consent of the Corporate Parties, which consent shall
not be unreasonably withheld, provided, however such consent will be deemed
given five (5) days after receipt of the material sought to be published if
consent is not withheld in writing. The Corporate Parties will cooperate with
each other in the development and distribution of all press releases and other
public announcements with respect to the Transactions, and will furnish the
other with drafts of any such releases and announcements as far in advance as
practicable, but in no event less than five (5) days prior to publication.

Section 7.5 No Third-Party Beneficiaries

            The terms and provisions of this Agreement are intended solely for
the benefit of each party hereto and their respective successors or permitted
assigns, and it is not the intention of the parties to confer third-party
beneficiary rights upon any other Person other than the SecurityVillage
Designees.

Section 7.6 Intentionally omitted.
