                                   ARTICLE III

                              CONVERSION OF SHARES

     3.1 VIDEO STOCK. At the VIDEO Effective Time, by virtue of the VIDEO Merger
and without any action on the part of any of the parties hereto or the holders
of any shares of the capital stock of SENTRY, VIDEO OR KNOGO, each share of
VIDEO common stock, par value $0.01 per share (the "VIDEO SHARES"), which is
issued and outstanding immediately prior to the VIDEO Effective Time shall be
converted into and represent the right to receive one share of common stock, par
value $0.001 per share, of SENTRY ("SENTRY COMMON STOCK") (the "VIDEO MERGER
CONSIDERATION"). All such VIDEO Shares shall no longer be outstanding and shall
automatically be canceled and extinguished and shall cease to exist, and each
certificate which immediately prior to the VIDEO Effective Time evidenced any
such VIDEO Shares ("VIDEO CERTIFICATES") shall thereafter represent the right to
receive (without interest), upon surrender of such VIDEO Certificate in
accordance with the provisions of Section 3.6, the VIDEO Merger Consideration
multiplied by the number of VIDEO Shares evidenced by such VIDEO Certificate.
The holders of VIDEO Certificates previously evidencing VIDEO Shares outstanding
immediately prior to the VIDEO Effective Time shall cease to have any rights
with respect thereto (including, without limitation, any rights to vote or to
receive dividends and distributions in respect of such VIDEO Shares), except as
otherwise provided herein or by law. At the VIDEO Effective Time, each VIDEO
Share held in VIDEO's treasury immediately prior to the Effective Time shall, by
virtue of the VIDEO Merger, be canceled and retired and cease to exist, without
any conversion thereof. All other classes of VIDEO stock held in treasury shall
also be canceled.

     3.2 KNOGO STOCK. At the KNOGO Effective Time, by virtue of the KNOGO Merger
and without any action on the part of any of the parties hereto or the holders
of any shares of the capital stock of SENTRY, VIDEO OR KNOGO, each 1.2022 shares
of KNOGO common stock, par value $0.01 per share (the "KNOGO SHARES"), which is
issued and outstanding immediately prior to the KNOGO Effective Time shall be
converted into and represent the right to receive one share of SENTRY Common
Stock (the "KNOGO COMMON STOCK CONSIDERATION"), plus one share of preferred
stock, par value $0.001 per share, of SENTRY ("SENTRY CLASS A PREFERRED STOCK";
such SENTRY Class A Preferred Stock having the terms set forth in EXHIBIT A
attached hereto) (together with the KNOGO Common Stock Consideration, the "KNOGO
MERGER CONSIDERATION" and with the VIDEO Merger Consideration, collectively, the
"Merger Consideration"). All such KNOGO Shares shall no longer be outstanding
and shall automatically be canceled and extinguished and shall cease to exist,
and each certificate which immediately prior to the KNOGO Effective Time
evidenced any such KNOGO Shares ("KNOGO CERTIFICATES") shall thereafter
represent the right to receive (without interest), upon surrender of such KNOGO
Certificate in accordance with the provisions of Section 3.6, the KNOGO Merger
Consideration multiplied by the number of KNOGO Shares evidenced by such KNOGO
Certificate. The holders of KNOGO Certificates previously evidencing KNOGO
Shares outstanding immediately prior to the KNOGO Effective Time shall cease to
have any rights with respect thereto (including, without limitation, any rights
to vote or to receive dividends and distributions in respect of such KNOGO
Shares), except as otherwise provided herein or by law. At the KNOGO Effective
Time, each KNOGO Share held in KNOGO's treasury immediately prior to the KNOGO
Effective Time shall, by virtue of the KNOGO Merger, be canceled and retired and
cease to exist, without any conversion thereof. All other classes of KNOGO stock
held in treasury shall also be canceled.

VMC (the "VMC COMMON STOCK") outstanding immediately prior to the VIDEO
Effective Time shall, by virtue of the VIDEO Merger and without any further
action by the holder thereof, be converted into and become one share of common
stock, par value $.001 per share, of the VIDEO Surviving Corporation (the "VIDEO
SURVIVING CORPORATION COMMON STOCK"). Each certificate which immediately prior
to the VIDEO Effective Time represented outstanding shares of VMC Common Stock
shall, on and after the VIDEO Effective Time, be deemed for all purposes to
represent the number of shares of VIDEO Surviving Corporation Common Stock into
which the shares of VMC Common Stock represented by such certificate shall have
been converted pursuant to this Section 3.4.

     3.5 SMC STOCK. Each share of common stock, par value $.001 per share, of
SMC (the "SMC COMMON STOCK") outstanding immediately prior to the KNOGO
Effective Time shall, by virtue of the KNOGO Merger and without any further
action by the holder thereof, be converted into and become one share of common
stock, par value $.001 per share, of the KNOGO Surviving Corporation (the "KNOGO
SURVIVING CORPORATION COMMON STOCK"). Each certificate which immediately prior
to the KNOGO Effective Time represented outstanding shares of SMC Common Stock
shall, on and after the KNOGO Effective Time, be deemed for all purposes to
represent the number of shares of KNOGO Surviving Corporation Common Stock into
which the shares of SMC Common Stock represented by such certificate shall have
been converted pursuant to this Section 3.5.

     3.6 EXCHANGE OF CERTIFICATES. (a) As of the Effective Time, SENTRY shall
deposit, or shall cause to be deposited, with an exchange agent mutually
selected by VIDEO and KNOGO (the "EXCHANGE AGENT"), for the benefit of the
holders of VIDEO Shares and KNOGO Shares, for exchange in accordance with this
Article III, certificates representing the shares of SENTRY Common Stock and
SENTRY Class A Preferred Stock (such certificates for shares of SENTRY Common
Stock and SENTRY Class A Preferred Stock, together with any dividends or
distributions with respect thereto (relating to record dates for such dividends
or distributions after the Effective Time), being hereinafter referred to as the
"EXCHANGE FUND") to be issued pursuant to this Article III and paid pursuant to
this Section 3.6 in exchange for outstanding VIDEO Shares and KNOGO Shares.

                    (b) Promptly after the Effective Time, SENTRY shall cause
the Exchange Agent to mail to each holder of record of VIDEO Shares (i) a letter
of transmittal which shall specify that delivery shall be effected, and risk of
loss and title to such VIDEO Shares shall pass, only upon delivery of the VIDEO
Certificates representing such VIDEO Shares to the Exchange Agent and which
shall be in such form and have such other provisions as SENTRY may reasonably
specify and (ii) instructions for use in effecting the surrender of such VIDEO
Certificates in exchange for certificates representing shares of SENTRY Common
Stock and cash in lieu of fractional shares. Upon surrender of a VIDEO
Certificate for cancellation to the Exchange Agent together with such letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, the holder of VIDEO Shares represented by such VIDEO Certificate shall
be entitled to receive in exchange therefor (x) a certificate representing that
number of whole shares of SENTRY Common Stock and (y) a check representing the
amount of cash in lieu of fractional shares (in accordance with Section 3.6(f)
below), if any, and unpaid dividends and distributions, if any, which such
holder has the right to receive in respect of the VIDEO Certificate surrendered
pursuant to the provisions of this Article III, after giving effect to any
required withholding tax, and the VIDEO Shares represented by the VIDEO
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or accrued on the cash in lieu of fractional shares and unpaid dividends and
distributions, if any, payable to holders of VIDEO Shares. In the event of a
transfer of ownership of VIDEO Shares which is not registered in the transfer
records of VIDEO, a certificate representing the proper number of shares of
SENTRY Common Stock, together with a check for the cash to be paid in lieu of
fractional shares (in accordance with Section 3.6(f) below), may be issued to
such a transferee if the VIDEO Certificate representing such VIDEO Shares is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and to evidence that any applicable stock
transfer taxes have been paid.

                    (c) Promptly after the Effective Time, SENTRY shall cause
the Exchange Agent to mail to each holder of record of KNOGO Shares (i) a letter
of transmittal which shall specify that delivery shall be effected, and risk of
loss and title to such KNOGO Shares shall pass, only upon delivery of the KNOGO
Certificates representing such KNOGO Shares to the Exchange Agent and which

specify and (ii) instructions for use in effecting the surrender of such KNOGO
Certificates in exchange for certificates representing shares of SENTRY Common
Stock, SENTRY Class A Preferred Stock and cash in lieu of fractional shares.
Upon surrender of a KNOGO Certificate for cancellation to the Exchange Agent
together with such letter of transmittal, duly executed and completed in
accordance with the instructions thereto, the holder of KNOGO Shares represented
by such KNOGO Certificate shall be entitled to receive in exchange therefor (x)
a certificate representing that number of whole shares of SENTRY Common Stock,
(y) a certificate representing that number of whole shares of SENTRY Class A
Preferred Stock, and (z) a check representing the amount of cash in lieu of
fractional shares (in accordance with Section 3.6(f) below), if any, and unpaid
dividends and distributions, if any, which such holder has the right to receive
in respect of the KNOGO Certificate surrendered pursuant to the provisions of
this Article III, after giving effect to any required withholding tax, and the
KNOGO Shares represented by the KNOGO Certificate so surrendered shall forthwith
be canceled. No interest will be paid or accrued on the cash in lieu of
fractional shares and unpaid dividends and distributions, if any, payable to
holders of KNOGO Shares. In the event of a transfer of ownership of KNOGO Shares
which is not registered in the transfer records of KNOGO, a certificate
representing the proper number of shares of SENTRY Common Stock and SENTRY Class
A Preferred Stock and a check for the cash to be paid in lieu of fractional
shares (in accordance with Section 3.6(f) below), may be issued to such a
transferee if the KNOGO Certificate representing such KNOGO Shares is presented
to the Exchange Agent, accompanied by all documents required to evidence and
effect such transfer and to evidence that any applicable stock transfer taxes
have been paid.

                    (d) Notwithstanding any other provisions of this Agreement,
no dividends or other distributions declared after the Effective Time on SENTRY
Common Stock or SENTRY Class A Preferred Stock shall be paid with respect to any
shares represented by a VIDEO or KNOGO Certificate, as the case may be, until
such Certificate is surrendered for exchange as provided herein. Subject to the
effect of applicable laws, following surrender of any such VIDEO or KNOGO
Certificate, there shall be paid to the holder of the certificates representing
whole shares of SENTRY Common Stock or SENTRY Class A Preferred Stock issued in
exchange therefor, without interest, (i) at the time of such surrender, the
amount of dividends or other distributions with a record date after the
Effective Time theretofore payable with respect to such whole shares of SENTRY
Common Stock or SENTRY Class A Preferred Stock and not paid, less the amount of
any withholding taxes which may be required thereon, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record date
after the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole shares of SENTRY Common Stock or
SENTRY Class A Preferred Stock, less the amount of any withholding taxes which
may be required thereon.

                    (e) At or after the VIDEO Effective Time, there shall be no
transfers on the stock transfer books of VIDEO of the VIDEO Shares which were
outstanding immediately prior to the VIDEO Effective Time. At or after the KNOGO
Effective Time, there shall be no transfers on the stock transfer books of KNOGO
of the KNOGO Shares which were outstanding immediately prior to the KNOGO
Effective Time. If, after the Effective Time, VIDEO or KNOGO Certificates are
presented to SENTRY, they shall be canceled and exchanged for certificates for
shares of SENTRY Common Stock (and SENTRY Class A Preferred Stock in the case of
KNOGO Shares) and cash in lieu of fractional shares (in accordance with Section
3.6(f) below), if any, deliverable in respect thereof pursuant to this Agreement
in accordance with the procedures set forth in this Article III. Certificates
surrendered for exchange by any person constituting an "affiliate" of KNOGO or
VIDEO for purposes of Rule 145(c) under the Securities Act of 1933, as amended
(the "SECURITIES ACT"), shall not be exchanged until SENTRY has received a
written agreement from such person as provided in Section 6.9.

                    (f) No fractional shares of SENTRY Common Stock or SENTRY
Class A Preferred Stock shall be issued pursuant hereto. As promptly as possible
following the Effective Time, the Exchange Agent shall determine the excess of
(i)(A) the number of full shares of SENTRY Common Stock delivered to the
Exchange Agent by SENTRY pursuant to Section 3.6(a) over (B) the number of full
shares of SENTRY Common Stock to be distributed to the holders of VIDEO Shares
and KNOGO Shares pursuant to Sections 3.6(b) and 3.6(c) (such excess being
herein referred to as the "Excess Common Shares"), and (ii)(A) the number of
full shares of SENTRY Class A Preferred Stock delivered to the Exchange Agent by
SENTRY pursuant to Section 3.6(a) over (B) the number of full shares of SENTRY
Class A Preferred Stock to be distributed to the holders of KNOGO Shares
pursuant to Sections 3.6(c) (such excess being herein referred to as the "Excess
Preferred Shares"). As soon after the Effective Date as practicable, the
Exchange Agent, as agent for the holders of SENTRY Common Stock and SENTRY Class
A Preferred Stock, shall sell the Excess Common Shares and Excess Preferred
Shares at the then prevailing prices on the NASDAQ Stock Market's National
Market ("NASDAQ"), or such other national securities exchange as is applicable,
through one or more member firms of NASDAQ, or other national securities
exchange, as the case may be, in round lots to the extent practicable. SENTRY
shall pay all commissions, transfer taxes and other out-of-pocket transactions
costs, including the expenses and compensation of the Exchange Agent incurred in
connection with such sale of the Excess Common Shares and Excess Preferred
Shares. Until the proceeds of such sale or sales have been distributed to the
holders of SENTRY Common Stock or SENTRY Class A Preferred Stock entitled to
receipt of such proceeds, the Exchange Agent shall hold such proceeds in trust
for those holders of SENTRY Common Stock and SENTRY Class A Preferred Stock. The
Exchange Agent shall determine the portion of the proceeds from the sale of (i)
the Excess Common Shares (the "Excess Common Shares Proceeds") to which each
holder of SENTRY Common Stock is entitled, if any, by multiplying the amount of
the Excess Common Shares Proceeds by a fraction, the numerator of which is the
amount of the fractional share interest to which such holder of SENTRY Common
Stock is entitled, and the denominator of which is the aggregate amount of
fractional share interests to which all of the holders of SENTRY Common Stock
are entitled, and (ii) the Excess Preferred Shares (the "Excess Preferred Shares
Proceeds") to which each holder of SENTRY Class A Preferred Stock is entitled,
if any, by multiplying the amount of the Excess Preferred Shares Proceeds by a
fraction, the numerator of which is the amount of the fractional share interest
to which such holder of SENTRY Class A Preferred Stock is entitled, and the
denominator of which is the aggregate amount of fractional share interests to
which all of the holders of SENTRY Class A Preferred Stock are entitled. As soon
as practicable after the sale of the Excess Common Shares and the Excess
Preferred Shares and the determination of the amount of cash, if any, to be paid
to each holder of SENTRY Common Stock and SENTRY Class A Preferred Stock in lieu
of any fractional share interests, the Exchange Agent shall distribute such
amounts to the holders of SENTRY Common Stock and SENTRY Class A Preferred Stock
entitled thereto and who have theretofore delivered VIDEO Certificates or KNOGO
Certificates for SENTRY Company Common Stock and/or SENTRY Class A Preferred
Stock, as the case may be, pursuant to this Article III.

                    (g) Any portion of the Exchange Fund (including the proceeds
of any investments thereof and any shares of SENTRY Common Stock and SENTRY
Class A Preferred Stock) that remains unclaimed by the former stockholders of
KNOGO or VIDEO one year after the Effective Time shall be delivered to SENTRY.
Any former stockholder of KNOGO or VIDEO who has not theretofore complied with
this Article III shall thereafter look only to SENTRY for payment of their
shares of SENTRY Common Stock, SENTRY Class A Preferred Stock, cash in lieu of
fractional shares and unpaid dividends and distributions on the SENTRY Common
Stock and SENTRY Class A Preferred Stock deliverable in respect of each VIDEO or
KNOGO Share such stockholder holds as determined pursuant to this Agreement, in
each case, without any interest thereon.

                    (h) None of VIDEO, KNOGO, SENTRY, VMC, SMC, the Exchange
Agent or any other person shall be liable to any former holder of VIDEO Shares
or KNOGO Shares for any amount properly delivered to a public official pursuant
to applicable abandoned property, escheat or similar laws.

                    (i) In the event any VIDEO or KNOGO Certificate shall have
been lost, stolen or destroyed, upon the making of an affidavit of that fact by
the person claiming such Certificate to be lost, stolen or destroyed and, if
required by SENTRY, the posting by such person of a bond in such reasonable
amount as SENTRY may direct as indemnity against any claim that may be made
against it with respect to such Certificate, the Exchange Agent will issue in
exchange for such lost, stolen or destroyed Certificate the shares of SENTRY
Common Stock (and SENTRY Class A Preferred Stock in the case of KNOGO Shares)
and cash in lieu of fractional shares (in accordance with Section 3.6(f) below),
and unpaid dividends and distributions on shares of SENTRY Common Stock (and
SENTRY Class A Preferred Stock in the case of KNOGO Shares) as provided in this
Section 3.6, deliverable in respect thereof pursuant to this Agreement.

     3.7 ADJUSTMENT OF MERGER CONSIDERATION. In the event that, (i) subsequent
to the date of this Agreement but prior to the VIDEO Effective Time, the
outstanding shares of VIDEO shall have been changed into a different number of
shares or a different claim as a result of a stock split, reverse stock split,
stock dividend, subdivision, reclassification, split, combination, exchange,
recapitalization or other similar transaction, or (ii) subsequent to the date of
this Agreement but prior to the KNOGO Effective Time, the outstanding shares of
KNOGO shall have been changed into a different number of shares or a different
claim as a result of a stock split, reverse stock split, stock dividend,
subdivision, reclassification, split, combination, exchange, recapitalization or
other similar transaction, then the Merger Consideration shall be appropriately
adjusted.

     3.8 VIDEO STOCK OPTIONS. (a) At the VIDEO Effective Time, all outstanding
options and other rights to acquire shares granted to employees under any stock
option or purchase plan, program or similar arrangement (each, as amended, an
"OPTION PLAN" and, such options and other rights, "STOCK Options") of VIDEO and,
with respect to employees and non-employees, all outstanding warrants to
purchase VIDEO Shares (the "Warrants"), whether or not such Stock Options or
Warrants are then exercisable or vested, will be assumed by SENTRY and shall be
exercisable upon the same terms and conditions as under the applicable Warrant
or Option Plan and option agreement issued thereunder, except that (i) each such
Stock Option or Warrant shall be exercisable for that whole number of shares of
SENTRY Common Stock (to the nearest share) into which the number of VIDEO Shares
subject to such Stock Option or Warrant immediately prior to the Effective Time
would be converted under Section 3.1, and (ii) the option exercise price or
Warrant exercise price per share of SENTRY Common Stock shall be an amount equal
to the option exercise price or warrant exercise price per VIDEO Share of such
Stock Option or Warrant in effect immediately prior to the VIDEO Effective Time
divided by the VIDEO Merger Consideration (the option exercise price or Warrant
exercise price per VIDEO Share, as so determined, being rounded upwards to the
nearest full cent). No payment shall be made for fractional interests.

                    (b) Except as provided herein or as otherwise agreed to by
the parties and to the extent permitted by the Option Plans, the Option Plans of
VIDEO shall terminate as of the VIDEO Effective Time and any rights under any
provisions in any other plan, program or arrangement providing for the issuance
or grant by VIDEO of any interest in respect of the capital stock of VIDEO shall
be canceled as of the VIDEO Effective Time.

     3.9 KNOGO STOCK OPTIONS. (a) At the KNOGO Effective Time, all outstanding
options and other rights to acquire Shares granted to employees under any Option
Plan of KNOGO, whether or not then exercisable or vested, will be assumed by
SENTRY and shall be exercisable upon the same terms and conditions as under the
applicable Option Plan and option agreement issued thereunder, except that
(A)(i) each such Stock Option shall be exercisable for that whole number of
shares of SENTRY Common Stock (to the nearest share) into which the number of
KNOGO Shares subject to such Stock Option immediately prior to the Effective
Time would be converted under Section 3.2, and (ii) each such Stock Option shall
be exercisable for that whole number of shares of SENTRY Class A Preferred Stock
(to the nearest share) into which the number of KNOGO Shares subject to such
Stock Option immediately prior to the Effective Time would be converted under
Section 3.2, provided that if all of the issued and outstanding SENTRY Class A
Preferred Stock has been theretofore redeemed or converted in the manner set
forth in the SENTRY Certificate of Incorporation, attached hereto as EXHIBIT A,
then in lieu of the SENTRY Class A Preferred Stock, the holders of such Stock
Options shall receive the same consideration paid to the holders of SENTRY Class
A Preferred Stock upon such redemption or conversion, and (B) the option
exercise price per share of SENTRY Common Stock (including SENTRY Class A
Preferred Stock) shall be an amount equal to the option exercise price per KNOGO
Share of such Stock Option in effect immediately prior to the KNOGO Effective
Time divided by the KNOGO Common Stock Consideration (the option exercise price
per KNOGO Share, as so determined, being rounded upwards to the nearest full
cent). No payment shall be made for fractional interests.

                    (b) Except as provided herein or as otherwise agreed to by
the parties and to the extent permitted by the Option Plans, the Option Plans of
KNOGO shall terminate as of the KNOGO Effective Time and any rights under any

consummate the transactions contemplated hereby in accordance with the terms
hereof (subject to the approval and adoption of this Agreement and the KNOGO
Merger by the holders of a majority of the outstanding KNOGO Shares, and the
filing and recordation of appropriate merger documents as required by the DGCL).
KNOGO's Board of Directors (the "KNOGO BOARD") has duly authorized the

its terms, except as may be limited by any bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws
affecting the enforcement of creditors' rights generally or by general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

     4.4 CONSENTS AND APPROVALS. (a) Neither the execution and delivery of this
Agreement by KNOGO nor the consummation by KNOGO of the transactions
contemplated hereby will require on the part of KNOGO any consent, approval,
authorization or permit of, or filing with or notification to, any governmental

applicable requirements of the Hart-Scott-Rodino Antitrust Improvements Act of

authorized to do business, (iv) as set forth in Section 4.4 of the KNOGO
Disclosure Schedule or (v) where the failure to obtain such consent, approval,
authorization or permit, or to make such filing or notification, would not have
a Material Adverse Effect on KNOGO or prevent the consummation of the
transactions contemplated hereby. The affirmative vote of the holders of a
majority of the outstanding KNOGO Shares is the only vote of the holders of
capital stock of KNOGO necessary to approve the KNOGO Merger.

                  (b) The KNOGO Board has approved the execution of the
Support/Voting Agreements to be entered into between KNOGO and certain VIDEO
stockholders.

     4.5 NO VIOLATION. Except as set forth in Section 4.5 of the KNOGO

any of its subsidiaries is a party or by which KNOGO, any of its subsidiaries,

acceleration or lien or other charge or encumbrance) as to which requisite
waivers or consents have been obtained or which would not have a Material
Adverse Effect on KNOGO or prevent the consummation of the transactions
contemplated hereby or (c) assuming the consents, approvals, authorizations or
permits and filings or notifications referred to in Section 4.4 and this Section
4.5 are duly and timely obtained or made and the approval of the KNOGO Merger by
the holders of a majority of the outstanding KNOGO Shares has been obtained,

Board of Directors of each of VIDEO and KNOGO shall recommend such approval and
VIDEO and KNOGO shall each take all lawful action to solicit such approval,
including, without limitation, timely mailing of the Joint Proxy

taken by, or upon authority of, the KNOGO Board or the VIDEO Board in the
exercise of its good faith judgment as to its fiduciary duties to its
stockholders imposed by law. VIDEO, as sole stockholder of SENTRY, and SENTRY,
as sole stockholder of VMC and SMC, shall as promptly as practicable duly

     6.4 REASONABLE EFFORTS. Subject to the terms and conditions of this
Agreement and applicable law, each of the parties shall act in good faith and

and to do, or cause to be done, all things necessary, proper or advisable to
consummate and make effective the transactions contemplated by this Agreement as
soon as practicable, including such actions or things as any other party may
reasonably request in order to cause any of the conditions to such other party's
obligation to consummate the transactions contemplated by this Agreement to be
fully satisfied. Without limiting the foregoing, the parties shall (and shall
cause their respective subsidiaries, and use commercially reasonable efforts to
cause their respective affiliates, directors, officers, employees, agents,
attorneys, accountants and representatives, to) consult and fully cooperate with
and provide assistance to each other in (a) the preparation and filing with the
SEC of the Joint Proxy Statement/Prospectus, and any necessary amendments or
supplements thereto; (b) seeking to have the Joint Proxy Statement/Prospectus
cleared by the SEC as soon as reasonably practicable after filing; (c) obtaining

governmental authority or instrumentality, domestic or foreign (collectively,
"GOVERNMENTAL ENTITY"), or other person or entity as soon as reasonably
practicable after filing; (d) seeking early termination of any waiting period

the other party a reasonable opportunity to comment on such drafts.

     6.5 PUBLIC ANNOUNCEMENTS. KNOGO, VIDEO, SENTRY, VMC and SMC will consult
with one another prior to issuing any release or otherwise making any public
statements with respect to the transactions contemplated hereby and shall not
issue any such press release or make any public statement prior to such
consultation, except as may be required by applicable law or any listing
agreement with a national securities exchange by which such party is bound.

     6.6 ACQUISITION PROPOSALS. Except as contemplated hereby, each of KNOGO and
VIDEO agree not to (and shall use reasonable efforts to cause its officers,
directors and employees and any investment banker, attorney, accountant, or
other agent retained by it not to) solicit, directly or indirectly, any proposal
or offer to acquire all or any significant part of its business and properties
or its capital stock, whether by merger, purchase of assets, tender offer or
otherwise (an "ACQUISITION PROPOSAL" and, any such transaction, an "ACQUISITION
TRANSACTION") or provide any non-public information concerning the respective
company to any third party in connection with an Acquisition Proposal.
Notwithstanding the foregoing, KNOGO and VIDEO may furnish information or cause
information to be furnished to, and may participate in discussions and
negotiations directly or through their respective representatives and enter into
an agreement relating to an Acquisition Proposal with, any third party
(including parties with whom KNOGO and VIDEO or their respective representatives
have had discussions on any basis on or prior to the date hereof) who makes an
unsolicited proposal or offer to it, if the KNOGO Board or VIDEO Board, as the
case may be, determines in good faith, after consultation with outside counsel,
that the failure to consider such proposal or offer could reasonably be deemed
to cause its directors to breach their fiduciary duties under applicable law. In
addition, nothing contained in this Agreement shall prohibit KNOGO or VIDEO and
their respective directors from (a) issuing a press release or otherwise
publicly disclosing the terms of any Acquisition Proposal, (b) taking and
disclosing to its stockholders any position, and making related filings with the
SEC, as required by Rules 14e-2 and 14d-9 under the Exchange Act with respect to
any tender offer or (c) taking any action and making any disclosure to its
stockholders which the KNOGO Board or VIDEO Board, as the case may be,
determines in good faith, after consultation with outside counsel, would likely
be required to be taken or made under applicable law (including, without
limitation, laws relating to the fiduciary duties of directors). In the event
KNOGO or VIDEO receives an Acquisition Proposal, it shall promptly inform the
other party as to the receipt of such Acquisition Proposal, unless the KNOGO
Board or VIDEO Board, as the case may be, determines, after consultation with
outside counsel, that giving such notice could reasonably be deemed to cause its
directors to breach their fiduciary duties under applicable law.

VIDEO shall promptly furnish all information as may be required for inclusion in
the Registration Statement on Form S-4 to be filed with the SEC in connection
with the issuance of shares of SENTRY Common Stock in the Reorganization (the
"REGISTRATION STATEMENT") and the joint proxy statement/prospectus which will
form a part thereof (the "JOINT PROXY STATEMENT/PROSPECTUS"). VIDEO and KNOGO
shall cooperate and promptly prepare and VIDEO shall file with the SEC as soon
as practicable the Registration Statement under the Securities Act. VIDEO shall
use reasonable efforts, and KNOGO will cooperate with VIDEO, to have the
Registration Statement declared effective by the SEC as promptly as practicable.
VIDEO shall use reasonable efforts to obtain, prior to the effective date of the
Registration Statement, all necessary state securities law or "blue sky" permits
or approvals required to consummate the transactions contemplated by this
Agreement. If at any time prior to the Effective Time, any information
pertaining to KNOGO or VIDEO contained in or omitted from the Registration
Statement makes such information false or misleading, KNOGO and VIDEO shall
promptly inform the other party and provide such other party with information
necessary to make the statements contained therein not misleading. No amendment
or supplement to the Joint Proxy Statement/Prospectus will be made by VIDEO or
KNOGO without the approval of the other party.

     6.8 LISTING APPLICATION. VIDEO shall promptly prepare and submit to NASDAQ,

Affiliates identified in the foregoing list, an Affiliate Letter in the form

specified in such Affiliate Letters on the certificates evidencing any SENTRY
Common Stock to be received by such KNOGO Affiliates pursuant to the terms of
this Agreement, and to issue appropriate stop transfer instructions to the
transfer agent for the SENTRY Common Stock, consistent with the terms of such

deliver to KNOGO a list of names and addresses of those persons who were, in
VIDEO's reasonable judgment, at the record date for VIDEO Stockholders' Meeting,
"affiliates" of VIDEO (each such person, a "VIDEO AFFILIATE") within the meaning
of Rule 145 of the rules and regulations promulgated under the Securities Act.
VIDEO shall provide KNOGO with such information and documents as KNOGO shall
reasonably request for purposes of reviewing such list. VIDEO shall use

providing at least the same coverage as the D&O Insurance currently maintained

neither SENTRY, the VIDEO Surviving Corporation nor the KNOGO Surviving
Corporation shall do anything that would forfeit, jeopardize, restrict or limit
the insurance coverage available for that claim until the final disposition

                                  ARTICLE VIII

                                   TERMINATION

                    (b) by either KNOGO or VIDEO, if the Effective Time shall
not have occurred on or before 180 days from the date hereof; PROVIDED, that the
right to terminate this Agreement under this clause (b) shall not be available
to any party whose misrepresentation in this Agreement or whose failure to
perform any of its covenants and agreements or to satisfy any obligation under
this Agreement has been the cause of or resulted in the failure of the
Reorganization to occur on or before such date;

                    (c) by either KNOGO or VIDEO, if (i) any federal or state
court of competent jurisdiction or other federal or state governmental or
regulatory body shall have issued any judgment, injunction, order or decree
prohibiting, enjoining or otherwise restraining the transactions contemplated by
this Agreement and such judgment, injunction, order or decree shall have become
final and nonappealable (PROVIDED, that the party seeking to terminate this
Agreement pursuant to this clause (c) shall have used commercially reasonable
efforts to remove such judgment, injunction, order or decree) or (ii) any
statute, rule, regulation or executive order promulgated or enacted by any
federal or state governmental authority after the date of this Agreement which
prohibits the consummation of the Reorganization shall be in effect;

                    (d) by either KNOGO or VIDEO, if this Agreement is not
adopted or the VIDEO Merger or the KNOGO Merger is not approved by the
stockholders of VIDEO or KNOGO as required by Section 7.1;

                    (e) by VIDEO, if there shall have been a material breach of
any representation, warranty or material covenant or agreement on the part of
KNOGO, which is not cured after thirty (30) days' written notice by VIDEO to
KNOGO; or

                    (f) by KNOGO, if there shall have been a material breach of
any representation, warranty or material covenant or agreement on the part of
VIDEO, which is not cured after thirty (30) days' written notice by KNOGO to
VIDEO.

                    (g) by either VIDEO or KNOGO, if (i) the KNOGO Board shall
withdraw or modify in a manner adverse to VIDEO its approval or recommendation
of the KNOGO Merger or shall have resolved to do any of the foregoing pursuant
to Section 6.6 or (ii) any Person or group of Persons shall have made an
Acquisition Proposal that the KNOGO Board determines in good faith, after
consultation with outside counsel, that the failure to accept such Acquisition
Proposal could reasonably be deemed to cause the members of the KNOGO Board to
breach their fiduciary duties under applicable law.

                    (h) by either KNOGO or VIDEO, if (i) the VIDEO Board shall
withdraw or modify in a manner adverse to KNOGO its approval or recommendation
of the VIDEO Merger or shall have resolved to do any of the foregoing pursuant
to Section 6.6 or (ii) any Person or group of Persons shall have made an
Acquisition Proposal that the VIDEO Board determines in good faith, after

liability or obligation hereunder, except in any such case (a) as provided in
Sections 6.2(b) (Confidentiality), 6.5 (Public Announcements) and 6.12 (Fees and
Expenses), which shall survive any such termination and (b) to the extent such
termination results from the breach by such party of any of its representations,
warranties, covenants or agreements contained in this Agreement.

by any party (whether by operation of law or otherwise) without the prior

this Agreement shall be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and assigns. Nothing in this
Agreement, expressed or implied, is intended to confer on any person other than

written instrument signed on behalf of the party or parties to be bound thereby.
No such extension or waiver shall constitute a waiver of, or estoppel with
respect to, any subsequent or other breach or failure to strictly comply with
the provisions of this Agreement. The failure of any party to insist on strict
compliance with this Agreement or to assert any of its rights or remedies
hereunder or with respect hereto shall not constitute a waiver of such rights or
remedies.

     9.8 VALIDITY. The invalidity or unenforceability of any provisions of this
Agreement shall not affect the validity or enforceability of any other
provisions of this Agreement, which shall remain in full force and effect.

meaning or interpretation of this Agreement.

                              AMENDED AND RESTATED

                          CERTIFICATE OF INCORPORATION

                                       OF

                          SENTRY TECHNOLOGY CORPORATION

                            (A DELAWARE CORPORATION)



          FIRST. The name of the corporation is SENTRY TECHNOLOGY CORPORATION
(the "Corporation").

          SECOND. The address of the Corporation's registered office in the
State of Delaware is Corporation Trust Center, 1209 Orange Street, Wilmington,
Delaware 19801. The name of the Corporation's registered agent at such address
is Corporation Trust Company.

          THIRD. The purpose of the Corporation is to engage in any lawful act
or activity for which corporations may be organized under the Delaware General
Corporation Law ("DGCL").

          FOURTH. The total number of shares of stock which the Corporation
shall have the authority to issue is one hundred million (100,000,000) shares of
common stock, par value $0.001 per share (the "Common Stock"), and twenty-five
million (25,000,000) shares of preferred stock, par value $0.001 per share (the
"Preferred Stock"), of which six million (6,000,000) shares shall be designated
Class A Preferred Stock (the "Class A Preferred Stock"). Each share of Class A
Preferred Stock shall have a face value of $5.00 (the "Face Value").

I.       COMMON STOCK.

          A statement of the designations, powers, preferences, rights,
qualifications, limitations and restrictions in respect of the Common Stock is
as follows:

          A. DIVIDENDS. Subject to the provisions of this Article FOURTH, the
Board of Directors (the "Board") of the Corporation may cause dividends to be
paid to the holders of shares of Common Stock out of funds legally available for
the payment of dividends by declaring an amount per share as a dividend.

          B. LIQUIDATION. Subject to the provisions of this Article FOURTH, in
the event of any voluntary or involuntary liquidation, dissolution or winding up
of the Corporation, the holders of shares of Common Stock shall be entitled to
share in all remaining assets of the Corporation available for distribution to
its stockholders.

          C. VOTING RIGHTS. Subject to the provisions of this Article FOURTH,
and except as otherwise required by law, each outstanding share of Common Stock
shall be entitled to vote on each matter on which the stockholders of the
Corporation shall be entitled to vote, and each holder of Common Stock shall be
entitled to one vote for each share of such stock held by such holder.

II.      PREFERRED STOCK.

          Shares of the Preferred Stock may be issued from time to time in one
or more classes or series, each of which class or series shall have such
distinctive designation or title as shall be set forth below or fixed by the
Board prior to the issuance of any shares thereof. Each such class or series of
the Preferred Stock shall be issued for such consideration and shall have such
voting powers, full or limited, or no voting powers, and such preferences and
relative participating optional and other special rights and such
qualifications, limitations or restrictions thereof, as shall be stated in such
resolution providing for the issue of such class or series of the Preferred
Stock as may be adopted from time to time by the Board prior to the issuance of
any shares thereof pursuant to the authority hereby expressly vested in it, all
in accordance with the laws of the State of Delaware. All shares of any one
class or series of the Preferred Stock shall be alike in every particular. The
Board is further authorized to increase or decrease (but not below the number of
such shares of series then outstanding) the number of shares of any series
subsequent to the issuance of shares of that series.

          Statements of the designations, powers, preferences, rights,
qualifications, limitations and restrictions in respect of the Class A Preferred
Stock are as follows:

         A.       CLASS A PREFERRED STOCK.

          1. RANK. The Class A Preferred Stock shall, with respect to dividend
rights and rights on liquidation, winding up or dissolution, rank (i) on parity
with, or junior to, as the case may be, any other class or series of Preferred
Stock established by the Board, the terms of which shall specifically provide
that such class or series shall rank on parity with, or senior to, the Class A
Preferred Stock with respect to dividend rights and rights on liquidation,
winding up or dissolution, and (ii) except as set forth below, prior to any
other equity securities of the Corporation with respect to dividend rights and
rights on liquidation, winding up or dissolution (all of such equity securities
of the Corporation to which the Class A Preferred Stock ranks prior, including
the Common Stock, are at times collectively referred to herein as the "Junior
Stock").

          2. DIVIDEND.

          (a) The annual dividend rate on each share of the Class A Preferred
Stock shall be fixed at five percent (5%) of the Face Value, payable in
accordance with this paragraph 2 (the "Dividend"). The holders of shares of the
Class A Preferred Stock shall be entitled to receive Dividends on the following
dates (each, a "dividend payment date"):           , 1997/8,           , 1998/9,
           , 1998/9,           , 1999/2000,           , 1999/2000 and
           , 2000/2001; the 12 month period ending on each of the first two 
dividend payment dates is an "annual dividend period," the six month period
ending on each of the next four dividend payment dates is a "semi-annual
dividend period" and each such annual dividend period or semi-annual dividend
period is a "dividend period." Dividends (whether or not declared) shall be
payable in additional shares of the Class A Preferred Stock during the two
annual dividend periods ending on the first two dividend payment dates
subsequent to issuance of the Class A Preferred Stock, such that holders shall
receive a Dividend of 1/20th of a share of Class A Preferred Stock for each
share of Class A Preferred Stock held. Thereafter, the holders of shares of the
Class A Preferred Stock shall be entitled to receive, in preference to dividends
on the Junior Stock, and whether or not declared the Dividend (including any
Dividend accrued and unpaid) payable in cash, out of funds legally available for
the payment of dividends, such that holders shall receive a Dividend of $0.25
for each share of Class A Preferred Stock held, which Dividend shall accrue
semi-annually and be due in equal installments on each of the last four dividend
payment dates. Dividends shall be paid on the applicable dividend payment date
to the holders of record at the close of business on the date (the "record
date") specified by the Board at the time such Dividend is declared; PROVIDED,
HOWEVER, that such record date shall not be more than 60 days nor less than 10
days prior to the applicable dividend payment date. For the purposes of this
paragraph, each additional share of the Class A Preferred Stock issued as a
Dividend shall be valued at the Face Value. Dividends (whether payable in cash
or in stock) shall be fully cumulative and shall accrue, with additional
payments thereon, from the first day of the dividend period in which such
Dividend may be payable as herein provided on all shares of the Class A
Preferred Stock issued and outstanding on the first day of such dividend period,
except that with respect to the initial dividend period, such Dividend shall
accrue from the date of issue. If the dividend payment date is not a business
day, the dividend payment date shall be the next succeeding business day.

          (b) All Dividends paid with respect to shares of the Class A Preferred
Stock pursuant to paragraph 2(a) shall be paid pro rata to the holders entitled
thereto.

          (c) If at any time the Corporation shall have failed to pay all
dividends which have accrued on any outstanding shares of any other class or
series of the Preferred Stock having cumulative dividend rights ranking on
parity with the shares of the Class A Preferred Stock at the times such
dividends are payable or the Corporation shall fail to redeem any of such stock
on the date set for the redemption thereof, no cash Dividend shall be declared
by the Board or paid or set apart for payment by the Corporation on shares of
the Class A Preferred Stock unless prior to or concurrently with such
declaration, payment or setting apart for payment, all accrued and unpaid
dividends on all outstanding shares of such other series of the Preferred Stock
shall have been or be declared, paid or set apart for payment, with additional
payments thereon, if any; PROVIDED, HOWEVER, that in the event such failure to
pay accrued dividends is with respect only to the outstanding shares of the
Class A Preferred Stock and any outstanding shares of any other class or series
of the Preferred Stock having cumulative dividend rights on parity with the
shares of the Class A Preferred Stock, cash dividends may be declared, paid or
set apart for payment, with additional payment thereon, pro rata on shares of
the Class A Preferred Stock and shares of such other class or series of the
Preferred Stock so that the amounts of any cash dividends declared, paid or set
apart for payment on shares of the Class A Preferred Stock and shares of such
other series of the Preferred Stock shall in all cases bear to each other the
same ratio that, at the time of such declaration, payment or setting apart for
payment, all accrued but unpaid cash dividends on shares of the Class A
Preferred Stock and shares of such other series of the Preferred Stock bear to
each other. Any Dividend not paid pursuant to paragraph 2(a) hereof or this
paragraph 2(c) shall be fully cumulative and shall accrue with additional
payments thereon, as set forth in paragraph 2(a) hereof.

          (d) (i) Holders of shares of the Class A Preferred Stock shall be
entitled to receive the Dividends provided for in paragraph 2(a) hereof in
preference to and in priority over any dividends other than dividends paid in
Junior Stock upon any of the Junior Stock.

          (ii) So long as any shares of the Class A Preferred Stock are
     outstanding, the Corporation shall not declare, pay or set apart for
     payment any dividend on any of the Junior Stock (other than dividends paid
     in such Junior Stock) or make any payment on account of, or set apart for
     payment money for a sinking or other similar fund for, the purchase,
     redemption or other retirement of, any of the Junior Stock or any warrants,
     rights, calls or options exercisable for any of the Junior Stock, or make
     any distribution in respect thereof, either directly or indirectly, and
     whether in cash, obligations or shares of the capital stock of the
     Corporation or other property (other than distributions or dividends in
     stock to the holders of such stock), and shall not permit any corporation
     or other entity directly or indirectly controlled by the Corporation to
     purchase or redeem any of the Junior Stock or any warrants, rights, calls
     or options exercisable for any of the Junior Stock, unless prior to or
     concurrently with such declaration, payment, setting apart for payment,
     purchase or distribution, as the case may be, all accrued and unpaid cash
     Dividends, including additional payments thereon, on shares of the Class A
     Preferred Stock not paid in accordance with the provisions of paragraph
     2(a) hereof shall have been or be paid and the Corporation shall have
     redeemed those shares of the Class A Preferred Stock required to be
     redeemed theretofore by the terms hereof.

          (e) Subject to the foregoing provisions of this paragraph 2, the Board
may declare and the Corporation may pay or set apart for payment dividends and
other distributions on any of the Junior Stock, and may purchase or otherwise
redeem any of the Junior Stock or any warrants, rights or options exercisable
for any of the Junior Stock; PROVIDED, HOWEVER, that a decision by the Board to
declare a dividend on any of the Junior Stock shall require approval by that
number of directors representing at least 662 2/3 percent of the Board, less any
vacancies on the Board. In such event, the holders of the Class A Preferred
Stock and the holders of such Junior Stock shall share equally, share and share
alike, in the distribution of any and all dividends declared on such Junior
Stock, provided that for this purpose each share of Class A Preferred Stock
shall be treated as one share of such Junior Stock.

          (f) The Corporation shall not be required to issue fractional shares
of Class A Preferred Stock as a result of the payment of Dividends. If any
fraction of a share of Class A Preferred Stock would be issuable upon the
payment of a Dividend, the Corporation may, in lieu of issuing such fractional
share, pay to such holder for any such fraction of a share an amount in cash
equal to the product obtained by multiplying (i) such fraction by (ii) the Face
Value.

          (g) Whenever, at any time or times, any Dividend payable shall be in
arrears, the holders of the outstanding shares of Class A Preferred Stock shall
have the right, voting separately as a class, to elect one director of the
Corporation. Upon the vesting of such right of the holders of Class A Preferred
Stock, the maximum authorized number of members of the Board shall automatically
be increased by one and the one vacancy so created shall be filled by vote of
the holders of the outstanding shares of Class A Preferred Stock. The right of
the holders of Class A Preferred Stock to elect a member of the Board as
aforesaid shall continue until such time as all Dividends in arrears shall have
been paid in full, at which time such right shall terminate, except as herein or
by law expressly provided, subject to revesting in the event of each and every
subsequent default of the character above described. Upon termination of such
special voting rights attributable to holders of the Class A Preferred Stock
pursuant to this paragraph, the term of office of any director elected by the
holders of shares of Class A Preferred Stock (any such director, a "Class A
Preferred Stock Director") pursuant to such special voting rights shall
immediately terminate and the number of directors constituting the entire Board
shall be reduced by one. Any Class A Preferred Stock Director may be removed by,
and shall not be removed otherwise than by, a majority vote of the outstanding
shares of Class A Preferred Stock. If the office of any Class A Preferred Stock
Director becomes vacant by reason of death, resignation, retirement,
disqualification, removal from office, or otherwise, a successor who shall hold
office for the unexpired term in respect of which such vacancy occurred shall be
elected by the holders of the outstanding shares of Class A Preferred Stock,
voting separately as a class.

                  3.       ADJUSTMENT OF HURDLE PRICE.

          (a) To preserve the actual or potential economic value of the Class A
Preferred Stock, if at any time after the date of this Amended and Restated
Certificate of Incorporation (the "Certificate"), there shall be any change in
the Common Stock, whether by reason of stock dividends, stock splits,
recapitalizations, mergers, consolidations, combinations or exchanges of
securities, split-ups, split-offs, spin-offs, liquidations, other similar
changes in capitalization, any distribution or issuance of cash, assets,
evidences of indebtedness or subscription rights, options or warrants to holders
of Common Stock (other than regular cash dividends) or otherwise, then, in each
such event the Board shall make such appropriate adjustments in the Hurdle Price
(as defined below) such that following such adjustments, such event shall not
have had the effect of increasing, reducing or limiting the benefits the holders
of shares of Class A Preferred Stock would have had absent such event.

          (b) The "Deemed Value" as used herein shall equal the Face Value plus
the amount by which the Closing Price exceeds the Hurdle Price on the date of
the relevant event. The "Hurdle Price" as used herein shall mean the amount that
is the average of the closing prices for a share of Sentry Common Stock on the
20 consecutive trading days ending on the trading date last preceding the first
anniversary of the filing of this Certificate; PROVIDED, HOWEVER, that in no
event shall the Hurdle Price be less than $5.00 or more than $6.50, such that
(x) if such average amount is less than $5.00 the Hurdle Price shall equal
$5.00, and (y) if such average amount is more than $6.50 the Hurdle Price shall
equal $6.50, subject to adjustment pursuant to paragraph 3 above. The "Closing
Price" as used herein shall mean the average of the closing prices for a share
of Common Stock on the twenty (20) consecutive trading days ending on the
trading date last preceding an optional redemption date, the Mandatory
Redemption Date (as defined below), the date of an event described in paragraph
4(a) above or the closing date of an Acquisition (as defined below), as the case
may be, as reported on the National Association of Securities Dealers, Inc.'s
Automated Quotations System ("Nasdaq") or if such closing prices shall not be
reported on Nasdaq, the average of the closing prices, regular way, for a share
of such security on the principal national securities exchange on which such
security is listed on such twenty (20) consecutive trading days, or if such
security is not listed on any national securities exchange, the average of the
mean between the closing bid and asked prices of a share of such security on
such twenty (20) consecutive trading days as reported, or if such prices shall
not be so reported, as the same shall be reported by the National Quotation
Bureau, Incorporated or, in all other cases, the value set in good faith by the
Board.

                  4.       LIQUIDATION PREFERENCE.

          (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the affairs of the Corporation, the holders of
shares of the Class A Preferred Stock then outstanding shall be entitled to be
paid out of the assets of the Corporation available for distribution to its
stockholders an amount in cash for each share outstanding equal to (i) the
Deemed Value on the date of such an event plus (ii) an amount in cash equal to
all accrued but unpaid Dividends thereon, plus additional dividends on unpaid
Dividends accrued prior to the commencement of the then-current dividend period,
to the date fixed for liquidation, before any payment shall be made or any
assets distributed to the holders of any of the Junior Stock. If the assets of
the Corporation are not sufficient to pay in full the liquidation payments
payable to the holders of outstanding shares of the Class A Preferred Stock and
any other class or series of the Preferred Stock having liquidation rights on
parity with the shares of the Class A Preferred Stock, then the holders of all
such shares shall share ratably in such distribution of assets in accordance
with the amount which would be payable on such distribution if the amounts to
which the holders of outstanding shares of the Class A Preferred Stock and the
holders of outstanding shares of such other series of the Preferred Stock are
entitled were paid in full.

          (b) The liquidation payment with respect to each fractional share of
the Class A Preferred Stock outstanding, if any, shall be equal to a ratably
proportionate amount of the liquidation payment with respect to each outstanding
share of the Class A Preferred Stock.

          (c) For purposes of this paragraph 4, neither the voluntary sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the
Corporation nor the consolidation or merger of the Corporation with one or more
other corporations shall be deemed to be a liquidation, dissolution or winding
up, voluntary or involuntary, unless such voluntary sale, conveyance, exchange
or transfer shall be in connection with a dissolution or winding up of the
business of the Corporation.

          (d) Any sale, lease or conveyance of all or substantially all of the
Corporation's assets or merger or consolidation of the Corporation which results
in the holders of the Common Stock receiving in exchange for such Common Stock
either cash or notes, debentures or other evidences of indebtedness or
obligations to pay cash or preferred stock of the surviving entity which ranks
on parity with the Class A Preferred Stock in liquidation or dividends shall be
deemed to be a liquidation, dissolution or winding up of the affairs of the
Corporation within the meaning of this paragraph 4. In the cases of merger or
consolidation of the Corporation where holders of the Common Stock receive, in
exchange for such Common Stock, common stock or preferred stock which is junior
in liquidation and dividends to the Class A Preferred Stock in the surviving
entity (whether or not such surviving entity is the Corporation) of such merger
or consolidation or preferred stock of another entity, the Class A Preferred
Stock shall be deemed to be preferred stock of such surviving entity or other
entity, as the case may be, with the same annual dividend rate and equivalent
rights to the rights set forth herein and the merger or consolidation agreement
shall expressly so provide. In the event of a merger or consolidation of the
Corporation where the consideration received by the holders of the Common Stock
consists of two or more of the types of consideration set forth above, the
holders of the Class A Preferred Stock shall be entitled to receive either cash
or securities based upon the foregoing in the same proportion as the holders of
the Common Stock of the Corporation are receiving cash or debt securities, or
equity securities in the surviving entity or another entity.

          (e) Notwithstanding paragraph 4(a), in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, the holders of Class A Preferred Stock shall receive the greater of
(i) the amount payable under paragraph 4(a) above or (ii) the amount which would
be the liquidation payment per share of Common Stock if the Class A Preferred
Stock were effectively redeemed for Common Stock prior to such liquidation, for
which purpose the Class A Preferred Stock shall be treated as representing an
equal number of shares of Common Stock.

                  5.       REDEMPTION.

          (a) OPTIONAL REDEMPTION. Prior to the first anniversary of the date of
issuance of the Class A Preferred Stock, the Corporation shall not redeem the
Class A Preferred Stock. Subject to the preceding sentence and the requirements
of paragraph 5(b) hereof, the Corporation may, at its option, redeem the Class A
Preferred Stock for cash, at any time in whole at the Deemed Value, together
with accrued and unpaid Dividends, if any, thereon. If the Corporation has
completed a Public Offering (as defined below) or an Acquisition more than 35
days prior to the Mandatory Redemption Date, then the Corporation may, at its
option, redeem the Class A Preferred Stock for Sentry Common Stock, in whole at
the Deemed Value, together with accrued and unpaid Dividends, if any, thereon,
subject to the following conditions: (i) the redemption shall be declared on the
closing date of such Public Offering or Acquisition, (ii) the redemption date
shall be fixed no later than 35 days after such closing date, (iii) for purposes
of determining the Deemed Value in the case of a Public Offering, the Closing
Price shall equal the price per share at which Common Stock is issued in such
Public Offering and (iv) for purposes of determining the Deemed Value in the
case of an Acquisition, the Closing Price shall be determined as of the closing
date of such Acquisition. "Public Offering" as used herein shall mean an
underwritten public offering of Common Stock with net proceeds resulting
therefrom in excess of $12,000,000. "Acquisition" as used herein shall mean an
acquisition by the Corporation of property of or securities issued by a third
party in which the consideration paid by the Corporation (i) consists, in whole
or in part, of shares of Common Stock and (ii) the aggregate value of such
shares of Common Stock exceeds $12,000,000; PROVIDED that such aggregate value
shall equal the number of such shares of Common Stock multiplied by the Closing
Price as of the closing date of such Acquisition.

          (b) MANDATORY REDEMPTION. On the fourth anniversary of the date of
issuance of the Class A Preferred Stock (the "Mandatory Redemption Date"), so
long as any shares of the Class A Preferred Stock shall be outstanding, the
Corporation shall redeem any issued and outstanding Class A Preferred Stock at
the Deemed Value, together with accrued and unpaid Dividends, if any, thereon,
for cash (to the extent the Corporation shall have funds legally available for
such payment) or Common Stock, at Sentry's option. The price of such Common
Stock shall be its Closing Price. To the extent that funds are not legally
available on the Mandatory Redemption Date for the payment in cash for the
mandatory redemption of the Class A Preferred Stock and the Corporation does not
issue Common Stock as payment for such mandatory redemption, the provisions of
paragraph 7 shall apply.

          (c) ACQUIRED SHARES. Shares of the Class A Preferred Stock which have
been issued and reacquired in any manner, including shares purchased or
redeemed, shall (upon compliance with any applicable provisions of the laws of
the State of Delaware) have the status of authorized and unissued shares of
Preferred Stock undesignated as to class or series and may be redesignated and
reissued as part of any class or series of the Preferred Stock; PROVIDED,
HOWEVER, that no such issued and reacquired shares of the Class A Preferred
Stock shall be reissued or sold as Class A Preferred Stock.

                  6.       PROCEDURE FOR REDEMPTION.

          (a) MANNER OF NOTICE. In the event the Corporation shall redeem shares
of the Class A Preferred Stock, notice of such redemption shall be given by
first class mail, postage prepaid, mailed not less than 30 days nor more than 60
days prior to the redemption date, to each holder of record of the shares to be
redeemed at such holder's address as the same appears on the stock register of
the Corporation. Each such notice shall state (i) the redemption date; (ii) the
aggregate number of shares of the Class A Preferred Stock to be redeemed; (iii)
the redemption payment and to what extent such redemption payment will be paid
in cash and/or Common Stock; (iv) the place or places where certificates for
such shares are to be surrendered for the redemption payment; and (v) that
Dividends on the shares to be redeemed will cease to accrue on such redemption
date.

          (b) EFFECT OF NOTICE; REDEMPTION. Notice having been mailed as
aforesaid, from and after the redemption date (unless default shall be made by
the Corporation in providing money for the payment of the redemption of the
shares so called for redemption), Dividends on the shares of the Class A
Preferred Stock so called for redemption shall cease to accrue, and said shares
shall no longer be deemed to be outstanding, and all rights of the holders
thereof as stockholders of the Corporation (except the right to receive from the
Corporation the redemption payment) shall cease. Upon surrender in accordance
with said notice of the certificates for any shares so redeemed (properly
endorsed or assigned for transfer, if the Board shall so require and the notice
shall so state), such shares shall be redeemed by the Corporation at the Deemed
Value plus accrued and unpaid Dividends.

                  7.       CONVERSION TO NOTES.

          (a) To the extent that funds are not legally available on the
Mandatory Redemption Date for the payment in cash for the mandatory redemption
of the Class A Preferred Stock, and the Corporation does not issue Common Stock
as payment for such mandatory redemption, as required herein, each outstanding
share of Class A Preferred Stock shall automatically convert (the "Conversion")
into a subordinated note (the "Subordinated Note") given by the Corporation for
the benefit of the holder thereof. Each Subordinated Note shall be in a
principal amount equal to the Deemed Value plus accrued and unpaid Dividends.
The Subordinated Notes (i) shall bear interest at a rate of six percent (6%) per
annum, (ii) shall mature at the end of one year from the date of Conversion, and
(iii) upon maturity, shall become due and payable as to any outstanding
principal and interest.

          (b) At the time of the Conversion, the holders of the Subordinated
Notes shall have the right, voting separately as a class, to elect one director
of the Corporation. Upon the vesting of such right of the holders of the
Subordinated Notes, the maximum authorized number of members of the Board shall
automatically be increased by one and the one vacancy so created shall be filled
by vote of the holders of the Subordinated Notes. The right of the holders of
the Subordinated Notes to elect a member of the Board as aforesaid shall
continue until such time as the Subordinated Notes have been paid in full, at
which time such right shall terminate, except as herein or by law expressly
provided. Upon termination of such special voting rights attributable to holders
of the Subordinated Notes pursuant to this paragraph, the term of office of any
director elected by the holders of Subordinated Notes (any such director, a
"Subordinated Notes Director") pursuant to such special voting rights shall
immediately terminate and the number of directors constituting the entire Board
shall be reduced by one. Any Subordinated Notes Director may be removed by, and
shall not be removed otherwise than by, a majority vote of the outstanding
Subordinated Notes. If the office of any Subordinated Notes Director becomes
vacant by reason of death, resignation, retirement, disqualification, removal
from office, or otherwise, a successor who shall hold office for the unexpired
term in respect of which such vacancy occurred shall be elected by a majority of
the outstanding Subordinated Notes, voting separately as a class.

          (c) The indebtedness represented by the Subordinated Notes and the
payment of the principal of and any interest on each and all of the Subordinated
Notes shall be subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness (as defined below). "Senior Indebtedness" as
used herein shall mean the principal of and premium, if any, and interest on (a)
all indebtedness of the Corporation for money borrowed, other than Preferred
Stock, whether outstanding as of the date hereof or thereafter created, incurred
or assumed, except indebtedness that by the terms of the instrument or
instruments by which such indebtedness was created or incurred expressly
provides that it (i) is junior in right of payment to the Subordinated Notes or
(ii) ranks PARI PASSU with the Subordinated Notes, (b) amendments, renewals,
extensions, modifications, refinancings and refundings of any such indebtedness
and (c) all of the Corporation's trade payables. For purposes of the preceding

                            FORM OF AFFILIATE LETTER




October   , 1996


Sentry Technology Corporation
[Address]
[Address]

Ladies and Gentlemen:

          I have been advised that as of the date of this letter I may be deemed
to be an "affiliate" of           , a           corporation (the "Company"), as
the term "affiliate" is (i) defined for purposes of paragraphs (c) and (d) of
Rule 145 of the rules and regulations (the "Rules and Regulations") of the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Securities Act"), or (ii) used in and for purposes of
Accounting Series, Releases 130 and 135, as amended, of the Commission. Pursuant
to the terms of the Agreement and Plan of Reorganization and Merger dated as of
October 10, 1996 (the "Merger Agreement"), by and among Video Sentry
Corporation, a Minnesota corporation ("Video"), Knogo North America Inc., a
Delaware corporation ("Knogo"), Sentry Technology Corporation, a Delaware
corporation ("Sentry"), Viking Merger Corp., a Minnesota corporation and wholly
owned subsidiary of Sentry ("Viking"), and Strip Merger Corp., a Delaware
corporation and wholly owned subsidiary of Sentry ("Strip"), Viking will be
merged with and into Video and Strip will be merged with and into Knogo (the
"Merger").

         As a result of the Merger, I may receive shares of the common stock,
par value $0.001 per share, of Sentry (the "Sentry Securities") in exchange
for shares owned by me of the common stock, par value $0.01 per share, 
of               . 

          I represent, warrant and covenant to Sentry that in the event I
received any Sentry Securities as a result of the Merger:

          A. I shall not make any sale, transfer or other disposition of the
Sentry Securities in violation of the Securities Act or the Rules and
Regulations.

          B. I have carefully read this letter and the Merger Agreement, and
discussed the requirements of such documents and other applicable limitations
upon my ability to sell, transfer or otherwise dispose of the Sentry Securities
to the extent I deemed necessary with my counsel or counsel for the Company.

          C. I have been advised that the issuance of Sentry Securities to me
pursuant to the Merger has been registered with the Commission under the
Securities Act on a Registration Statement on Form S- 4. However, I have also
been advised that, since at the time the Merger was submitted for a vote of the
stockholders of the Company, I may be deemed to have been an affiliate of the
Company and the distribution by me of the Sentry Securities has not been
registered under the Securities Act, I may not sell, transfer or otherwise
dispose of the Sentry Securities issued to me in the Merger unless (i) such
sale, transfer or other disposition has been registered under the Securities
Act, (ii) such sale, transfer or other disposition is made in conformity with
Rule 145 promulgated by the Commission under the Securities Act, or (iii) in the
opinion of counsel reasonably acceptable to Sentry, or pursuant to a "no action"
letter obtained by the undersigned from the staff of the Commission, such sale,
transfer or other disposition is otherwise exempt from registration under the
Securities Act.

          D. I understand that Sentry is under no obligation to register the
sale, transfer or other disposition of the Sentry Securities by me or on my
behalf under the Securities Act or to take any other action necessary in order
to make compliance with an exemption from such registration available.

          E. I also understand that stop transfer instructions will be given to
Sentry's transfer agents with respect to the Sentry Securities and that there
will be placed on the certificates for the Sentry Securities issued to me, or
any substitutions therefor, a legend stating in substance:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
          TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
          1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE
          TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED
          __________________, 1996 BETWEEN THE REGISTERED HOLDER HEREOF AND
          SENTRY TECHNOLOGY CORPORATION, A COPY OF WHICH AGREEMENT IS ON FILE AT
          THE PRINCIPAL OFFICES OF SENTRY TECHNOLOGY CORPORATION."

         F. I also understand that unless the transfer by me of my Sentry
Securities has been registered under the Securities Act or is a sale made in
conformity with the provisions of Rule 145, Sentry reserves the right to place
the following legend on the certificates issued to my transferee:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO
         RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED
         UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED
         BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY
         DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933
         AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
         ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT OF 1933."

          It is understood and agreed that the legends set forth in paragraphs E
and F above shall be removed by delivery of substitute certificates without such
legend if such legend is not required for purposes of the Securities Act or this
Agreement. It is understood and agreed that such legends and the stop orders
referred to above will be removed if (i) two years shall have elapsed from the
date the undersigned acquired the Sentry Securities received in the Merger and
the provisions of Rule 145(d)(2) are then available to the undersigned, (ii)
three years shall have elapsed from the date the undersigned acquired the Sentry
Securities received in the Merger and the provisions of Rule 145(d)(3) are then
available to the undersigned, or (iii) Sentry has received either an opinion of
counsel, which opinion and counsel shall be reasonably satisfactory to Sentry,
or a "no action" letter obtained by the undersigned from the staff of the
Commission, to the effect that the restrictions imposed by Rule 145 under the
Securities act no longer apply to the undersigned.

          Execution of this letter should not be considered an admission on my
part that I am an "affiliate" of the Company as described in the first paragraph
of this letter or as a waiver of any rights I may have to object to any claim
that I am such an affiliate on or after the date of this letter.

                                    Very truly yours,




                                    Name:

                      VIDEO SENTRY AND KNOGO NORTH AMERICA
                             REVISE MERGER AGREEMENT

NEW YORK, NY, DECEMBER 5, 1996--Video Sentry Corporation (Nasdaq: VSEN), a
pioneer in traveling video security systems, and KNOGO North America Inc. (AMEX:
KNA), a leading manufacturer of Electronic Article Surveillance (EAS) systems,
today announced that they have filed with the Securities and Exchange Commission
(SEC) a preliminary proxy/prospectus with respect to their proposed merger into
a new publicly traded entity to be called Sentry Technology Corporation (STC).
The merger, which has been unanimously approved by both boards of directors, is
subject to approval by the holders of a majority of the outstanding common stock
of both companies. In this regard, the companies announced that they expect to
mail proxy materials to their respective shareholders after completing SEC
review and anticipate that the shareholder meetings and closing may occur in
late January 1997. They also announced that they have amended their outstanding
merger agreement, originally executed in October 1996, to clarify certain
details and to link the redemption hurdle price on the STC Preferred shares
(i.e., the price over which STC Common share appreciation is taken into account
in the STC Preferred share redemption price) more closely to the market price of
STC Common shares. Instead of equaling a fixed price of $6.50 per share, the
hurdle price shall equal the STC Common share price one year from the date of
closing but not less than $5.00 or more than $6.50.

     Video Sentry Corporation, headquartered in Minneapolis, MN, is the industry
leader in the design, manufacture and marketing of a patented traveling closed
circuit television (CCTV) surveillance system.

     KNOGO North America Inc., headquartered in Long Island, NY, designs,
manufactures, sells and services EAS and Closed Circuit Video equipment in the
United States and Canada to deter shoplifting and other types of theft for
retailers, supermarkets, libraries and commercial enterprises. KNOGO is a
spin-off of KNOGO Corporation, founder of the EAS industry 30 years ago.
