Item 3.  Source and Amount of Funds or Other Consideration.

         This Statement is being filed as a result of the execution by the
Reporting Persons of the Stockholder Voting Agreements (as defined below), and

Item 4.  Purpose of Transaction.

         On May 5, 1998, ADT and AAC entered into the Agreement and Plan of
Merger (the "Merger Agreement," a copy of which is attached hereto and made a
part hereof as Exhibit A). The Merger Agreement provides, among other things,
for the merger of AAC with and into ADT (the "Merger"), with ADT as the
surviving corporation (the "Surviving Corporation"). Upon the issuance of
capital stock of AAC, John K. Mangini shall own 66 2/3% of the voting securities
of AAC and 399 Venture Partners, Inc. ("399") shall own 33 1/3% of the voting
securities of AAC.

         Under the terms of the Merger Agreement, which is subject to majority
shareholder approval, each Share (or fraction thereof) issued and outstanding
immediately prior to the Effective Time (as defined below) (other than any
Shares to be canceled (as described below), any shares to remain outstanding (as
described below) and any Dissenting Shares (as defined in the Merger Agreement),
shall be canceled and shall be converted automatically into the right to receive
an amount equal to $5.00 in cash payable, without interest, to the holder of
such Share, upon surrender of the Certificate that formerly evidenced such
Share. 75,000 of the Shares held by and registered in the names of certain ADT
Stockholders immediately prior to the Effective Time who are members of
management of the Company shall not be canceled but shall remain outstanding and
become shares of Class A common stock, $.01 par value per share, of the


<PAGE>




Surviving Corporation ("Class A Common Stock"). In addition, all of (a) the
issued and outstanding shares of common stock, par value $.01 per share, of AAC,
(b) the issued and outstanding shares of preferred stock, par value $.01 per
share of AAC, and (c) 1,100,110 Shares of ADT Common Stock held by and
registered in the name of 399, shall be converted into 74,000 shares of Class A

common stock, 351,000 shares of Class B Common Stock, $.01 par value per share,
of the Surviving Corporation and 165,000 shares of Series A preferred stock, par
value $.01 per share, of the Surviving Corporation. The Merger will become
effective at such time as the certificate of merger is duly filed with the
Secretary of State of the State of Delaware or at such later time as is
specified in the certificate of merger (the "Effective Time"). From and after
the Effective Time, the Surviving Corporation will possess all the rights,
privileges, powers and franchises and be subject to all of the restrictions,
disabilities and duties of ADT and AAC, all as provided under Delaware Law. The
Merger is subject to customary conditions, including the approval and adoption
of the Merger Agreement by the affirmative vote of a majority of the
stockholders of ADT.

         In connection with the Merger, each of the Reporting Persons entered
into a stockholder voting agreement (collectively, the "Shareholder Voting
Agreements") with AAC dated as of May 5, 1998 (copies of which are attached
hereto and made a part hereof as Exhibits B through D) representing in the
aggregate 8,233,641 Shares, which together with the Shares currently owned by
399 represent approximately 66.58% of the Shares issued and outstanding.

         During the period (the "Agreement Period") beginning on May 5, 1998 and
ending on the Termination Date (as defined in the Merger Agreement), each of the
Reporting Persons has agreed not to directly or indirectly (i) except pursuant
to the terms of the Merger Agreement or the Stockholders Voting Agreement, offer
for sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose
of, enforce or permit the execution of the provisions of any redemption
agreement with ADT or enter into any contract, option or other arrangement or
understanding with respect to or consent to the offer for sale, transfer,
tender, pledge, encumbrance, assignment or other disposition of, or exercise any
discretionary powers to distribute, any or all of such Reporting Person's Shares
or any interest therein, including any trust income or principal, except in each
case to a permitted transferee (a "Permitted Transferee"), who is or agrees to
become bound by the Stockholder Voting Agreement; (ii) except as contemplated by
the Stockholder Voting Agreement, grant any proxies or powers of attorney with
respect to any Shares, deposit any Shares into a voting trust or enter into a
voting agreement with respect to any Shares; or (iii) take any action that would
make any representation or warranty of such Reporting Person contained in the
Stockholder Voting Agreement untrue or incorrect or have the effect of
preventing or disabling such Reporting Person from performing such Stockholder's
obligations under the Stockholder Voting Agreement.

         Each Reporting Person has waived any rights of appraisal or rights to
dissent from the Merger that such Reporting Person may have. The Stockholders
have represented that no beneficiary who is a beneficial owner of Shares under
any trust has any right of appraisal or right to dissent from the Merger which
has not been so waived.

         Each Reporting Person has agreed that, until the termination Date, such
Reporting Person shall vote (or cause to be voted) the Shares held of record or
beneficially by such Reporting Person (i) in favor of the Merger, the execution
and delivery by ADT of the Merger Agreement and the approval of the terms
thereof and each of the other actions contemplated by the Merger Agreement and
the Stockholder Voting Agreement and any actions required in furtherance hereof
and thereof; (ii) against any action or agreement that would result in a breach

of any covenant, representation or warranty or any other obligation or agreement
of ADT under the Merger Agreement or the Stockholder Voting Agreement; and (iii)
against the following actions (other than the Merger and the transactions
contemplated by the Merger Agreement or


<PAGE>


any such actions identified in writing by AAC in advance): (A) any extraordinary
corporate transaction, including, without limitation, a merger, consolidation or
other business combination involving ADT or its Subsidiaries; (B) a sale, lease
or transfer of a material amount of assets of ADT or its Subsidiaries or a
reorganization, recapitalization, dissolution or liquidation of ADT or its
Subsidiaries; (C) any change in the majority of the board of directors of ADT;
(D) any material change in the present capitalization of ADT or any amendment of
ADT's Certificate of Incorporation or By-Laws; (E) any other material change in
ADT's corporate structure or business; or (F) any other action which is
intended, or could reasonably be expected, to impede, interfere with, delay,
postpone, discourage or materially adversely affect the Merger or the
transactions contemplated by the Merger Agreement or the Stockholder Voting
Agreement.

         Each Reporting Person has appointed AAC and any designee of AAC, each
of them individually, such Stockholder's irrevocable (until the termination
Date) proxy and attorney-in-fact (with full power of substitution) to vote such
Stockholder's Shares as described above. The proxy is irrevocable (until the
Termination Date) and coupled with an interest. Each Reporting Person has agreed
to take such further action and execute such other instruments as may be
necessary to effectuate the intent of the proxy and has revoked any proxy
previously granted by such Reporting Person with respect to such Stockholder's
Shares.

         The Shareholder Voting Agreements will terminate upon the expiration
of the Agreement Period.

         Subject to the terms and provisions of the Merger Agreement, in
connection with the Merger, each of Charles A. Mantione, John K. Mangini, John
J. Mangini, Emily M. Hill, Steven Granat, Edward Simek, David R. Conrad, Brian
Wilson and Donald L. Olesen (and various parties related to Donald L. Olesen)
(the "Rollover Stockholders") has entered into a Rollover Agreement with AAC
dated as of May 5, 1998 whereby each has agreed to elect to retain an aggregate
of 75,000 Shares of Surviving Corporation Common Stock upon conversion of, and
with respect to, 75,000 Shares owned by the Rollover Stockholder immediately
prior to the Effective Time (the "Rollover Shares") unless otherwise agreed with
AAC.

         Unless the Shares held by any trust which are presently subject to the
terms of the Rollover Agreement are transferred to one or more Rollover
Stockholders (and remain subject in all respects to the terms of the Rollover
Agreement) or other Permitted Transferees who upon receipt of such Shares become
signatories to the Rollover Agreement, the Rollover Stockholders who are
trustees shall not take any action to terminate, close or liquidate any such
trust and shall take all steps necessary to maintain the existence thereof at

least until the Termination Date.

         Each Rollover Stockholder has waived any rights of appraisal or rights
to dissent from the Merger that such Stockholder may have. The Rollover
Stockholders have represented that no beneficiary who is a beneficial owner of
Shares under any trust has any right of appraisal or right to dissent from the
Merger which has not been so waived.

                                       12

          (2) Treasury Stock and AAC-owned Shares. At and as of the Effective

          (3) Certain of the Shares held by and registered in the names of
certain Company Stockholders who are members of management of the Company (the

the Company and Anchor Bay Entertainment (the "Anchor Bay Option") and is
outstanding immediately prior to the Effective Time (whether or not vested or

therefor, each holder of each such Option shall receive a cash payment which,
prior to deduction for applicable withholding Taxes, is in an amount equal to
the product of (A) the excess, if any, of the Per Share Amount over the per
share exercise price of such Option and (B) the number of shares subject to the
Option (whether or not vested). If the per share exercise price of any such
Option


                                       13

<PAGE>

thereof shall have the right to receive only $5 per share, and in no event shall

Surviving Corporation.

     (9) Dissenting Shares. Notwithstanding any provisions of the Agreement to
the contrary, Shares of Company Common Stock which are issued and outstanding
immediately prior to the Effective Time and which are held by a Company
Stockholder who has not voted such Shares in favor of the Merger, who shall have
delivered a written demand for appraisal of such Shares in the manner provided
by the DGCL and who, as of the Effective Time, shall not have effectively
withdrawn or lost such right to appraisal ("Dissenting Shares") shall not be
converted into a right to receive the Merger Consideration. The holders thereof
shall be entitled only to such rights as are granted by Section 262 of the DGCL.
Each holder of Dissenting Shares who becomes entitled to payment for such Shares
pursuant to Section 262 of the DGCL shall receive payment therefor from the
Surviving Corporation in accordance with the DGCL; provided, however, that (i)
if any such holder of Dissenting Shares shall have failed to establish his
entitlement to appraisal rights as provided in Section 262 of the DGCL, (ii) if
any such holder of Dissenting Shares shall have effectively withdrawn his demand
for appraisal of such Shares or lost his right to appraisal and payment for his
Shares under Section 262 of the DGCL or (iii) if neither any holder of
Dissenting Shares nor the Surviving Corporation shall have filed a petition
demanding a determination of the value of all Dissenting Shares within the time
provided in Section 262 of the DGCL, such holder shall forfeit the right to
appraisal of such Shares and each such Share shall be treated as if such Share
had been converted, as of the Effective Time, into a right to receive the Merger
Consideration, without interest thereon, from the Surviving Corporation as
provided in this Section 2. The Company shall give AAC prompt notice of any
demands received by the Company for appraisal of Shares, and, until the
Effective Time, AAC


                                       14

<PAGE>





shall have the right to participate in all negotiations and proceedings with
respect to such demands. The Company shall not, except with the prior written
consent of AAC, make any payment with respect to, or settle or offer to settle,
any such demands.

     (10) Surrender of Shares; Stock Transfer Books.

          (1) Prior to the Effective Time, AAC shall designate a bank or trust
company (which bank or trust company shall be reasonably acceptable to the
Company) to act as agent (the "Paying Agent") for the holders of Shares in
connection with the Merger to receive the funds to which holders of Shares shall
become entitled pursuant to Section 2(g)(i) and shall deposit with the Paying
Agent the proceeds of the Debt Financing required in order to consummate the
Transactions. Such funds shall be invested by the Paying Agent as directed by
the Surviving Corporation, provided that such investments shall be in
obligations of or guaranteed by the United States of America or of any agency

thereof and backed by the full faith and credit of the United States of America,
in commercial paper obligations rated A-1 or P-1 or better by Moody's Investors
Service, Inc. or Standard & Poor's Corporation, respectively, or in deposit
accounts, certificates of deposit or banker's acceptances of, repurchase or
reverse repurchase agreements with, or Eurodollar time deposits purchased from,
commercial banks with capital, surplus and undivided profits aggregating in
excess of $1.0 billion (based on the most recent financial statements of such
bank which are then publicly available at the SEC or otherwise).

          (2) Promptly after the Effective Time, the Surviving Corporation shall
cause to be mailed to each Person who was, at the Effective Time, a holder of
record of Shares entitled to receive the Merger Consideration pursuant to
Section 2(g)(i), a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
evidencing Shares (the "Certificates") shall pass, only upon proper delivery of
the Certificates to the Paying Agent) and instructions for use in effecting the
surrender of the Certificates pursuant to such letter of transmittal. Upon
surrender to the Paying Agent of a Certificate, together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, and such other documents as may be required pursuant to
such instructions, the holder of such Certificate shall be entitled to receive
in exchange therefor the Merger Consideration for each Share formerly evidenced
by such Certificate, and such Certificate shall then be canceled. No interest
shall accrue or be paid on the Merger Consideration payable upon the surrender
of any Certificate for the benefit of the holder of such Certificate. If payment
of the Merger Consideration is to be made to a Person other than the Person in
whose name the surrendered Certificate is registered on the stock transfer books
of the


                                       15

<PAGE>





Company, it shall be a condition of payment that the Certificate so surrendered
shall be endorsed properly or otherwise be in proper form for transfer and that
the Person requesting such payment shall have paid all transfer and other Taxes
required by reason of the payment of the Merger Consideration to a Person other
than the registered holder of the Certificate surrendered or shall have
established to the satisfaction of the Surviving Corporation that such Taxes
either have been paid or are not applicable.

          (3) At any time following the sixth month after the Effective Time,
the Surviving Corporation shall be entitled to require the Paying Agent to
deliver to it any funds which had been made available to the Paying Agent and
not disbursed to holders of Shares (including, without limitation, all interest
and other income received by the Paying Agent in respect of all funds made
available to it), and thereafter such holders shall be entitled to look to the
Surviving Corporation (subject to abandoned property, escheat and other similar
laws) only as general creditors thereof with respect to any Merger Consideration

that may be payable upon due surrender of the Certificates held by them to the
fullest extent permitted by law. Notwithstanding the foregoing, to the fullest
extent permitted by law, neither the Surviving Corporation nor the Paying Agent
shall be liable to any holder of a Share for any Merger Consideration delivered
in respect of such Share to a public official pursuant to any abandoned
property, escheat or other similar law.

          (4) Any portion of the Merger Consideration made available to the
Paying Agent to pay for Shares of Company Common Stock for which appraisal
rights have been perfected shall be paid to the Surviving Corporation upon
demand.

          (5) At the Effective Time, the stock transfer books of the Company
shall be closed to the extent permitted by applicable law and thereafter there
shall be no further registration of transfers of Shares on the records of the
Company. From and after the Effective Time, the holders of Shares outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such Shares except as otherwise provided herein or by applicable law.

          (6) The Surviving Corporation shall pay all charges and expenses of
the Paying Agent.

     (1) Organization, Qualification, and Corporate Power. Each of the Company
and its Subsidiaries is a corporation duly organized, validly existing, and in
good standing under the laws of the jurisdiction of its incorporation. Each of
the Company and its Subsidiaries has full corporate power and authority to carry
on the businesses in which it is engaged and to own and use the properties owned
and used by it. Each of the Company and its Subsidiaries is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except for those jurisdictions
where the failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect.

     (2) Capitalization. (i) The authorized capital stock of the Company
consists of 25,000,000 Shares of Company Common Stock and 1,000,000 shares, $.01
par value per share, of preferred stock (the "Company Preferred Stock"). As of
the date of this Agreement: (A) 13,623,394 Shares of Company Common Stock were
issued and outstanding, (B) no shares of Company Preferred Stock were issued or
outstanding, and (C) no Shares of Company Common Stock were held by the Company

in its treasury. All of the issued and outstanding Shares of Company Common
Stock have been duly authorized and are validly issued, fully paid, and
nonassessable. Except as indicated in Schedule 3(b), there are no outstanding or
authorized options, warrants, purchase rights, subscription rights, conversion
rights, exchange rights or other contracts or commitments that could require the
Company or any Subsidiary thereof to issue, sell, or otherwise cause to become
outstanding any of its capital stock or the capital stock of any Subsidiary
thereof. There are no outstanding or authorized stock appreciation, phantom
stock, profit participation or similar rights with respect to the Company or any
of its Subsidiaries. All shares of capital stock of Subsidiaries of the Company
are wholly owned directly or indirectly by the Company and have been duly
authorized and are validly issued, fully paid and nonassessable.

                  (ii) Except as provided in Schedule 3(b), there are no voting

Subsidiary thereof.

                  (iii) The Class A Warrants and Class B Warrants expire on July
28, 1998 and the Class C Warrants expire on January 11, 2000. Upon consummation
of the Transactions, the Warrants, Substitute Options and Anchor Bay Option
shall have been adjusted so that, in the case of each Warrant (other than any
Warrant that has expired in accordance with its terms) or applicable Option,
upon exercise and payment of the exercise price, any holder thereof shall have
the right to receive only $5 per share, and in


                                       17

<PAGE>





no event shall have the right to receive any shares of capital stock of the
Company or the Surviving Corporation.

     (3) Authorization of Transactions. The Company has, and subject to the
Requisite Stockholder Approval will have, full power and authority to execute
and deliver this Agreement and to perform its obligations hereunder. The
execution and delivery by the Company of this Agreement and the Merger, and the
performance of the Company's obligations hereunder, have been and, subject to
the Requisite Stockholder Approval or Requisite Super-Majority Stockholder
Approval, as the case may be, will be, duly authorized by all requisite
corporate action, and this Agreement has been executed and delivered by the
Company. This Agreement constitutes the valid and legally binding obligation of
the Company, enforceable in accordance with its terms and conditions.

     (4) Noncontravention. Neither the execution and the delivery of this
Agreement, nor the consummation of the Transactions contemplated hereby, will
(i) violate any constitution, statute, regulation, rule, injunction, judgment,
order, decree, ruling, charge or other restriction of any Governmental or
Regulatory Body or court to which any of the Company and its Subsidiaries is

subject, including, without limitation, Section 203 of the DGCL, or any
provision of the certificate of incorporation or bylaws of any of the Company
and its Subsidiaries or (ii) conflict with, result in a breach of, constitute a
default under, result in the acceleration of, create in any Party the right to
accelerate, terminate, modify, or cancel or require any notice under any
Contract to which any of the Company and its Subsidiaries is a party or by which
it is bound or to which any of its assets is subject, except where the
violation, conflict, breach, default, acceleration, termination, modification,
cancellation or failure to give notice would not have a Material Adverse Effect
or a material adverse effect on the ability of the Parties to consummate the
Transactions. Other than in connection with the provisions of the HSR Act, the
DGCL, the Securities Exchange Act, the Securities Act, the state securities
laws, and as set forth on Schedule 3(d), none of the Company and its
Subsidiaries needs to give any notice to, make any filing with, or obtain any
authorization, consent or approval of any Governmental or Regulatory Body in
order for the Parties to consummate the Transactions or execute, deliver and
perform its obligations under this Agreement, except where the failure to give
notice, to file, or to obtain any authorization, consent or approval would not
have a Material Adverse Effect or a material adverse effect on the ability of
the Parties to consummate the Transactions.

     (5) Filings with the SEC. Since July 31, 1994, the Company and its
Subsidiaries have made all filings with the SEC that are required under the
Securities Act and the Securities Exchange Act (collectively, the "SEC

the Securities Exchange Act and the rules and regulations promulgated thereunder
in all material respects. None of the SEC Reports, as of their respective dates,
contained any untrue statement of a material fact or omitted to state a material
fact necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading. The Company has
heretofore furnished or made available to AAC complete and correct copies of all
amendments and modifications that have not been filed by the Company with the
SEC to all agreements, documents and other instruments that previously had been
filed by the Company with the SEC and are currently in effect.

     (6) Financial Statements. The Company has delivered to AAC an Annual Report
on Form 10-K of the Company for the fiscal year ended July 31, 1997 (the "Most
Recent Fiscal Year End"). The financial statements included in or incorporated
by reference into such SEC Reports (including the related notes and schedules)
have been prepared in accordance with GAAP and present fairly the financial
condition of the Company and its Subsidiaries as of the indicated dates and the
results of operations of the Company and its Subsidiaries for the indicated
periods.

Fiscal Year End, there has not been any Material Adverse Effect with respect to

connection with the Transactions and (ii) as and to the extent disclosed in the
SEC Reports or as set forth in Schedule 3(h), since July 31, 1997, neither the
Company nor any of its Subsidiaries has incurred any Liabilities of any nature
(whether accrued, absolute, contingent or otherwise) which could reasonably be
expected to be required to be reflected in or reserved against on a consolidated
balance sheet, or in the notes thereto, of the Company and its consolidated
Subsidiaries prepared in accordance with GAAP consistent with past practice.

     (9) Brokers' Fees. Other than fees related to financial advisory services
performed for the Company to be paid to the Persons set forth on Schedule 3(i),
neither the Company nor any of its Subsidiaries has any Liability or obligation
to pay any fees or commissions to any broker, finder or agent with respect to
the Transactions. The Company has furnished to AAC true, correct and complete
copies of engagement letters relating to such services.

Stockholders if such action would require any director or officer of the Company
either to violate any requirement imposed by law in connection therewith or,
after consultation with and advice from its outside counsel, any director or
officer of the Company determines in good faith that to take such action would
be inconsistent with

impede, interfere with, prevent or materially delay the Merger or which would,
or could reasonably be expected to, materially dilute the benefits to AAC of the
Transactions (collectively, the "Acquisition Proposals" and which, if

in any discussions (except as may be necessary to inform a Third Party of the
provisions of this Section 5(k)) or negotiations regarding any of the foregoing,
or furnish to any Third Party any information with respect to the business,
properties or assets of the Company in connection with the foregoing, or

that, in the exercise of its fiduciary responsibilities, such discussions or
negotiations should be commenced or such information should be furnished or such
facilitation, cooperation, encouragement or participation undertaken; (y)
furnishing information pursuant to an appropriate and customary confidentiality
letter (which shall not be substantially less restrictive than the

Acquisition Proposal as to which a prior determination of the Board of Directors
of the Company as contemplated under clause (x) above has been made; provided,

authorize any officers or representatives to, take any of the foregoing actions
until notice to AAC of the Company's intent to take such action shall have been
given; and (2) if the Board of Directors of the Company receives a Superior
Acquisition Proposal, to the extent it may do so without breaching its fiduciary
duties as determined in good faith after consultation with its outside counsel,
and without violating any of the conditions of such Superior Acquisition
Proposal, then the Company shall promptly inform AAC of the material terms and
conditions of such proposal and the identity of the Third Party making it; or
(z) taking a position on a tender offer by a Third Party, as required by Rule
14e-2 under the Securities Exchange Act (provided no such position shall
constitute a recommendation of such transaction if it does not constitute a
Superior Acquisition Proposal) or complying with its duties of disclosure under
applicable state law. As of the date hereof, the Company shall immediately cease
and shall cause each of its Subsidiaries and its and their advisors, agents and
other intermediaries to cease, any and all existing activities, discussions or

                                       38

5(k)(ii)(B)(1) above) shall have been consummated within twelve months following
the termination of this Agreement, the Company shall pay to AAC, within ten (10)
Business Days following such occurrence, a fee of $3.375 million as liquidated

collecting the fees and other amounts provided for in this Section 5(k)(ii),
which out-of-pocket costs, fees and expenses shall be no more than $1 million in
the aggregate (collectively, the "Fixed Amount"). Notwithstanding the foregoing,
if the Company breaches any representation, warranty, covenant or other
agreement hereunder, the Fixed Amount paid by Company and actually received by
AAC shall be credited against the amount of damages awarded to AAC as a result
of such breach and any damages awarded to AAC as a result of such breach shall

                  beneficial owner of the number of, or (B) trustee of a trust
                  that is the record holder or beneficial owner of, and whose
                  beneficiaries are the beneficial owners (such trustee, a

                  set forth opposite the Stockholder's name on Schedule I hereto
                  (the "Existing Shares").

                           (ii) On the date hereof, the Existing Shares set
                  forth opposite the Stockholder's name on Schedule I hereto
                  constitute all of the outstanding shares of Company Common
                  Stock owned of record or beneficially by the Stockholder. The
                  Stockholder does not have record or beneficial ownership of
                  any Shares not set forth on Schedule I hereto.


                           (iii) The Stockholder has sole power of disposition
                  with respect to all of the Existing Shares set forth opposite

                  with respect to the matters set forth in Section 4 hereof and
                  sole power to demand dissenter's or appraisal rights, in each
                  case with respect to all of the Existing Shares set forth
                  opposite the Stockholder's name on Schedule I, with no
                  restrictions on such rights, subject to applicable federal
                  securities laws and the terms of this Agreement.

                           (iv) The Stockholder will have sole power of
                  disposition with respect to Shares other than Existing Shares,
                  if any, which become beneficially owned by the Stockholder and
                  will have sole voting power with respect to the matters set
                  forth in Section 4 hereof and sole power to demand dissenter's
                  or appraisal rights, in each case with respect to all Shares
                  other than Existing Shares, if any, which become beneficially
                  owned by the Stockholder with no restrictions on such rights,
                  subject to applicable federal securities laws and the terms of
                  this Agreement.

                  (b) The Stockholder has the legal capacity, power and
         authority to enter into and perform all of the Stockholder's
         obligations under this Agreement. Other than as set forth in Schedule
         2(b), the execution, delivery and performance of this Agreement by the
         Stockholder will not violate any other agreement to which the
         Stockholder is a party or by which the Stockholder is bound including,
         without limitation, any trust agreement, voting agreement, stockholders
         agreement, voting trust, partnership or other agreement. This Agreement
         has been duly and validly executed and delivered by the Stockholder and
         constitutes a valid and binding agreement of the Stockholder,
         enforceable against the Stockholder in accordance with its terms,
         except as limited by (a) bankruptcy, insolvency, 

                                       4

<PAGE>

         reorganization, moratorium or other similar laws relating to creditor's
         rights generally, (b) general principles of equity, whether such
         enforceability is considered in a proceeding in equity or at law, and
         to the discretion of the court before which any proceeding therefore
         may be brought, or (c) public policy considerations or court decisions
         which may limit the rights of the parties thereto for indemnification.
         All necessary consents of any beneficiary of or holder of interest in
         any trust of which a Stockholder is Trustee to the execution and
         delivery of this Agreement and the consummation of the transactions
         contemplated hereby have been obtained. If the Stockholder is married
         and the Stockholder's Shares constitute community property, this
         Agreement has been duly authorized, executed and delivered by, and
         constitutes a valid and binding agreement of, the Stockholder's spouse,
         enforceable against such person in accordance with its terms.

                  (c) (i) No filing with, and no permit, authorization, consent

         or approval of, any state or federal public body or authority is
         necessary for the execution of this Agreement by the Stockholder and
         the consummation by the Stockholder of the transactions contemplated
         hereby and (ii) neither the execution and delivery of this Agreement by
         the Stockholder nor the consummation by the Stockholder of the
         transactions contemplated hereby nor compliance by the Stockholder with
         any of the provisions hereof shall (x) conflict with or result in any
         breach of any applicable trust, partnership agreement or other
         agreements or organizational documents applicable to the Stockholder,
         (y) result in a violation or breach of, or constitute (with or without
         notice or lapse of time or both) a default (or give rise to any third
         party right of termination, cancellation, material modification or
         acceleration) under any of the terms, conditions or provisions of any
         note, bond, mortgage, indenture, license, contract, commitment,
         arrangement, understanding, agreement or other instrument or obligation
         of any kind to which the Stockholder is a party or by which the
         Stockholder or any of the Stockholder's properties or assets may be
         bound or (z) violate any order, writ, injunction, decree, judgment,
         statute, rule or regulation applicable to the Stockholder or any of the
         Stockholder's properties or assets.

                  (d) Except for the shares of Company Common Stock identified
         in Schedule II hereto (the "Pledged Shares"), the Stockholder's Shares
         and the certificates representing such Shares are now and at all times
         during the term hereof will be held by the Stockholder, or by a nominee
         or custodian for the benefit of the Stockholder, free and clear of all
         liens, claims, security interests, proxies, voting trusts or
         agreements, understandings or arrangements or any other encumbrances

         Stockholder in his or her capacity as such.

hereby represents and warrants to the Stockholder as follows:

                  (a) Purchaser is a corporation duly organized, validly

         approval which shall be effected prior to the Effective Time. This
         Agreement has been duly executed and delivered by Purchaser, and

         proceeding therefor may be brought, or (c) public policy considerations
         or court decisions which may limit the rights of the parties thereto
         for indemnification.

                  (c) The execution and delivery of this Agreement do not, and
         the consummation by Purchaser of the transactions contemplated by this
         Agreement and compliance by Purchaser with the provisions of this
         Agreement will not, conflict with, or result in any breach or violation
         of, or default (with or without notice or lapse of time, or both)

         acceleration of or "put" right with respect to any obligation or to
         loss of a material benefit under, or result in the creation of any lien
         upon any of the properties or assets of Purchaser under, (i) any
         charter or by-laws of

         assets or (iii) any judgment, order, decree, statute, law, ordinance,
         rule, regulation or arbitration award applicable to Purchaser or its

         Stockholder (i) in favor of the Merger, the execution and delivery by
         the Company of the Merger Agreement and the approval of the terms
         thereof and each of the other actions contemplated by the Merger

         transactions contemplated by the Merger Agreement or this Agreement.
         The Stockholder shall not enter into any agreement or understanding
         with any person or entity to vote or give instructions in any manner
         inconsistent with clauses (i) or (ii) of the preceding sentence.

                  (b) THE STOCKHOLDER HEREBY GRANTS TO, AND APPOINTS, PURCHASER
         AND ANY DESIGNEE OF PURCHASER, EACH OF THEM INDIVIDUALLY, THE
         STOCKHOLDER'S IRREVOCABLE (UNTIL THE TERMINATION DATE) PROXY AND
         ATTORNEY-IN-FACT (WITH FULL POWER OF SUBSTITUTION) TO VOTE THE SHARES
         AS SET FORTH IN SECTION 4(a) ABOVE. THE STOCKHOLDER INTENDS THIS PROXY
         TO BE IRREVOCABLE (UNTIL THE TERMINATION DATE) AND COUPLED WITH AN
         INTEREST AND WILL TAKE SUCH FURTHER ACTION AND EXECUTE SUCH OTHER
         INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY
         AND HEREBY REVOKES ANY PROXY PREVIOUSLY GRANTED BY THE STOCKHOLDER WITH
         RESPECT TO THE STOCKHOLDER'S SHARES.

         Section 5. Certain Covenants of the Stockholder. Except in accordance
with the terms of this Agreement, the Stockholder hereby covenants and agrees as
follows:

                  (a) Prior to the Termination Date, no Stockholder shall, in
         its capacity as such, directly or indirectly (including through

         advisors, agents or other intermediaries), solicit (including by way of
         furnishing information) or respond to any inquiries or the making of
         any proposal by any person or entity (other than Purchaser or any
         Affiliate thereof) with respect to the Company that constitutes or
         could reasonably be expected to lead to an Acquisition Proposal. If the
         Stockholder in its capacity as such receives any such inquiry or
         proposal, then the Stockholder shall within 24 hours furnish Purchaser
         with an accurate description of the material terms (including any
         changes or adjustments to such terms as a result of negotiations or
         otherwise) and conditions, if any, of such inquiry or proposal and the
         identity of the person making it. The Stockholder, in its capacity as
         such, will immediately cease and cause to be terminated any existing
         activities, discussions or negotiations with any parties conducted
         heretofore with respect to any of the foregoing; provided, that the
         limitation set forth in this sentence shall not restrict the
         Stockholder from engaging in any such activities with such a third
         party who hereafter makes a Superior Acquisition Proposal. The
         foregoing provisions of this Section 5(a) shall not restrict a
         Stockholder who is also a director of the Company from taking any
         actions, or refraining from complying with the foregoing provision, in
         the Stockholder's capacity as a director, provided 



                                       8

<PAGE>

         that any such actions do not violate Section 5(k) of the Merger
         Agreement.

                  (b) Prior to the Termination Date, the Stockholder shall not,
         directly or indirectly (i) except pursuant to the terms of the Merger
         Agreement or this Agreement, offer for sale, sell, transfer, tender,
         pledge, encumber, assign or otherwise dispose of, enforce or permit the
         execution of the provisions of any redemption agreement with the
         Company or enter into any contract, option or other arrangement or
         understanding with respect to or consent to the offer for sale, sale,
         transfer, tender, pledge, encumbrance, assignment or other disposition
         of, or exercise any discretionary powers to distribute, any or all of
         the Stockholder's Shares or any interest therein, including any trust
         income or principal, except in each case to a Permitted Transferee who
         is or agrees to become bound by this Agreement; (ii) except as
         contemplated hereby, grant any proxies or powers of attorney with
         respect to any Shares, deposit any Shares into a voting trust or enter
         into a voting agreement with respect to any Shares; or (iii) take any
         action that would make any representation or warranty of the
         Stockholder contained herein untrue or incorrect or have the effect of
         preventing or disabling the Stockholder from performing the
         Stockholder's obligations under this Agreement.

                  (c) The Stockholder hereby waives any rights of appraisal or
         rights to dissent from the Merger that the Stockholder may have. The
         Trustee represents that no beneficiary who is a beneficial owner of

         Shares under any trust has any right of appraisal or right to dissent
         from the Merger which has not been so waived.

                  (d) Unless, in connection therewith, the Shares held by any
         trust which are presently subject to the terms of this Agreement are
         transferred to the Stockholder and remain subject in all respects to
         the terms of this Agreement, or other Permitted Transferees who upon
         receipt of such Shares become signatories to this Agreement, the
         Stockholder who is a Trustee shall not take any action to terminate,
         close or liquidate any such trust and shall take all steps necessary to
         maintain the existence thereof at least until the first to occur of (i)
         the Effective Time and (ii) the Termination Date.

         Section 6. Further Assurances. From time to time, at the other party's
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further action as may be
necessary or desirable to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement.

                                       9

<PAGE>

         Section 7. Certain Events. The Stockholder agrees that this Agreement
and the obligations hereunder shall attach to the Stockholder's Shares and shall
be binding upon any person or entity to which legal or Beneficial Ownership of
such Shares shall pass, whether by operation of law or otherwise, including
without limitation the Stockholder's heirs, guardians, administrators or
successors or as a result of any divorce.

         Section 8. Stop Transfer. The Stockholder agrees with, and covenants
to, Purchaser that the Stockholder shall not request that the Company register
the transfer (book-entry or otherwise) of any certificate or uncertificated
interest representing any of the Stockholder's Shares, unless such transfer is
made in compliance with this Agreement.

         Section 9. Termination. The obligations of the Stockholder and the
irrevocable proxy contained in Section 4(b) of this Agreement shall terminate
upon the first to occur of (a) the Effective Time and (b) the date the Merger
Agreement is terminated in accordance with its terms (the "Termination Date");
provided that the provisions of Sections 2, 3, 9 and 10 and any claim for breach
of any representation, warranty, covenant or other agreement under this
Agreement shall survive the Effective Time and/or the Termination Date, as
applicable.

         Section 10. Miscellaneous.

                  (a) Notices. All notices, requests, demands and other
         communications under this Agreement shall be in writing and shall be
         deemed to have been duly given (i) on the day of service if served
         personally on the party to whom notice is to be given; (ii) on the day
         of transmission if sent via facsimile transmission to the facsimile
         number given below, and telephonic confirmation of receipt is obtained
         promptly after completion of transmission, provided that a copy shall

         be sent via certified mail, return receipt requested, simultaneously
         with any such facsimile; (iii) on the business day after delivery to
         Federal Express or similar overnight courier or the Express Mail
         service maintained by the United States Postal Service; or (iv) on the
         fifth day after mailing, if mailed to the party to whom notice is to be

                  (b) At any time prior to the Effective Time, any party hereto
         may, with respect to any other party hereto, (i) extend the time for
         the performance of any of the obligations or other acts, (ii) waive any

                  (c) The headings contained in this Agreement are for the
         convenience of reference purposes only and shall not affect in any way
         the meaning or interpretation of this Agreement.

         invalid, illegal or incapable of being enforced by any rule of law or
         public policy, all other conditions and provisions of this Agreement
         shall nevertheless remain in full force and effect so long as the

         economic or legal substance of the transactions contemplated by the
         Merger Agreement is not affected in any manner adverse to any party.
         Upon such determination that any term or other provision is invalid,
         illegal or incapable of being enforced, the parties hereto shall
         negotiate in good faith to modify this Agreement so as to effect the
         original intent of the parties as closely as possible in an acceptable
         manner.

                  (e) This Agreement, including all exhibits, disclosure
         schedules and

         schedules hereto, constitutes the entire agreement and supersedes all
         prior agreements and undertakings, both written and oral, among the
         parties, or any of them, with respect to the subject matter hereof and
         except as otherwise expressly provided herein.

                  (f) Neither this Agreement nor any of the rights or
         obligations hereunder may be assigned by any party (whether by
         operation of law or otherwise) without the prior written consent of the
         other parties hereto. Subject to the preceding sentence, this Agreement
         shall be binding upon and inure to the benefit of the parties hereto
         and their respective successors and permitted assigns, and no other
         Person shall have any right, benefit or obligation under this Agreement
         as a third party beneficiary or otherwise.

                  (g) The parties hereto agree that irreparable damage would
         occur in the event that any of the provisions of this Agreement were
         not performed in accordance with their specific terms. It is
         accordingly agreed that the parties hereto shall be entitled to
         specific performance of the terms hereof, this being in addition to any
         other remedy to which they are entitled at law or in equity.

                  (h) No failure or delay on the part of any party hereto in the
         exercise of any right hereunder shall impair such right or be construed
         to be a waiver of, or acquiescence in, any breach of any
         representation, warranty or agreement herein, nor shall any single or
         partial exercise of any such right preclude other or further exercise
         thereof or of any other right. All rights and remedies existing under
         this Agreement are cumulative to, and not exclusive of, any rights or
         remedies otherwise available.

                  (i) Notwithstanding anything herein to the contrary, no Person
         executing this Agreement who is, or becomes during the term hereof, a
         director of the Company makes any agreement or understanding herein in
         his or her capacity as such director, and the agreements set forth
         herein shall in no way restrict any director in the exercise of his or
         her fiduciary duties as a director of the Company. The Stockholder has
         executed this Agreement solely in his or her capacity as the record or

         beneficial holder of the Stockholder's Shares or as the trustee of a
         trust whose beneficiaries are the beneficial owners of the
         Stockholder's Shares.

                  (j) Each party agrees to bear its own expenses in connection
         with the transactions contemplated hereby.

                  (k) This Agreement shall be governed and construed in
         accordance with the laws of the State of New York, without giving
         effect to any choice of law 

                                       12

         or conflict of law provision or rule that would cause the application
         of the laws of any jurisdiction other than the State of New York,
         except to the extent that the General Corporation Law of the State of
         Delaware applies as a result of the Company being incorporated in the
         State of Delaware, in which case such General Corporation Law shall
         apply.

                  (l) EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY
         WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS
         AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT AND
         FOR ANY COUNTERCLAIM THEREIN.

                  (m) This Agreement may be executed in one or more
         counterparts, and by the different parties hereto in separate
         counterparts, each of which when executed shall be deemed to be an
         original but all of which taken together shall constitute one and the
         same agreement.

         its capacity as such, directly or indirectly (including through
         advisors, agents or other intermediaries), solicit (including by way of
         furnishing information) or respond to any inquiries or the making of
         any proposal by any person or entity (other than Purchaser or any

         actions, or refraining from complying with the foregoing provision, in
         the Stockholder's capacity as a director, provided

         directly or indirectly (i) except pursuant to the terms of the Merger
         Agreement or this Agreement, offer for sale, sell, transfer, tender,
         pledge, encumber, assign or otherwise dispose of, enforce or permit the
         execution of the provisions of any redemption agreement with the
         Company or enter into any contract, option or other arrangement or
         understanding with respect to or consent to the offer for sale, sale,
         transfer, tender, pledge, encumbrance, assignment or other disposition
         of, or exercise any discretionary powers to distribute, any or all of
         the Stockholder's Shares or any interest therein, including any trust
         income or principal, except in each case to a Permitted Transferee who
         is or agrees to become bound by this Agreement; (ii) except as
         contemplated hereby, grant any proxies or powers of attorney with
         respect to any Shares, deposit any Shares into a voting trust or enter
         into a voting agreement with respect to any Shares; or (iii) take any
         action that would make any representation or warranty of the
         Stockholder contained herein untrue or incorrect or have the effect of
         preventing or disabling the Stockholder from performing the
         Stockholder's obligations under this Agreement.

                  (c) The Stockholder hereby waives any rights of appraisal or
         rights to dissent from the Merger that the Stockholder may have. The
         Trustee represents that no beneficiary who is a beneficial owner of
         Shares under any trust has any right of appraisal or right to dissent
         from the Merger which has not been so waived.

                  (d) Unless, in connection therewith, the Shares held by any
         trust which are presently subject to the terms of this Agreement are
         transferred to the Stockholder and remain subject in all respects to
         the terms of this Agreement, or other Permitted Transferees who upon
         receipt of such Shares become signatories to this Agreement, the
         Stockholder who is a Trustee shall not take any action to terminate,
         close or liquidate any such trust and shall take all steps necessary to
         maintain the existence thereof at least until the first to occur of (i)
         the Effective Time and (ii) the Termination Date.

         Section 6. Further Assurances. From time to time, at the other party's
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further action as may be
necessary or desirable to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement.

         Section 7. Certain Events. The Stockholder agrees that this Agreement
and the obligations hereunder shall attach to the Stockholder's Shares and shall
be binding upon any person or entity to which legal or Beneficial Ownership of
such Shares shall pass, whether by operation of law or otherwise, including
without limitation the Stockholder's heirs, guardians, administrators or
successors or as a result of any divorce.

         Section 8. Stop Transfer. The Stockholder agrees with, and covenants
to, Purchaser that the Stockholder shall not request that the Company register

interest representing any of the Stockholder's Shares, unless such transfer is
made in compliance with this Agreement.

         Section 9. Termination. The obligations of the Stockholder and the
irrevocable proxy contained in Section 4(b) of this Agreement shall terminate
upon the first to occur of (a) the Effective Time and (b) the date the Merger
Agreement is terminated in accordance with its terms (the "Termination Date");
provided that the provisions of Sections 2, 3, 9 and 10 and any claim for breach
of any representation, warranty, covenant or other agreement under this
Agreement shall survive the Effective Time and/or the Termination Date, as
applicable.

         Section 10. Miscellaneous.

         previously furnished to the others in writing in the manner set forth
         above.

                  (b) At any time prior to the Effective Time, any party hereto
         may, with respect to any other party hereto, (i) extend the time for
         the performance of any of the obligations or other acts, (ii) waive any
         inaccuracies in the representations and warranties contained herein or
         in any document delivered pursuant hereto or (iii) waive compliance
         with any of the agreements or conditions contained herein. Any such
         extension or waiver shall be valid if set forth in an instrument in
         writing signed by the party or parties to be bound thereby.

                  (c) The headings contained in this Agreement are for the
         convenience of reference purposes only and shall not affect in any way
         the meaning or interpretation of this Agreement.

                  (d) If any term or other provision of this Agreement is
         invalid, illegal or incapable of being enforced by any rule of law or
         public policy, all other conditions and provisions of this Agreement
         shall nevertheless remain in full force and effect so long as the
         economic or legal substance of the transactions contemplated by the
         Merger Agreement is not affected in any manner adverse to any party.
         Upon such determination that any term or other provision is invalid,
         illegal or incapable of being enforced, the parties hereto shall
         negotiate in good faith to modify this Agreement so as to effect the
         original intent of the parties as closely as possible in an acceptable
         manner.

                  (e) This Agreement, including all exhibits, disclosure

schedules and


                                       11

         schedules hereto, constitutes the entire agreement and supersedes all
         prior agreements and undertakings, both written and oral, among the
         parties, or any of them, with respect to the subject matter hereof and
         except as otherwise expressly provided herein.

                  (f) Neither this Agreement nor any of the rights or
         obligations hereunder may be assigned by any party (whether by
         operation of law or otherwise) without the prior written consent of the
         other parties hereto. Subject to the preceding sentence, this Agreement
         shall be binding upon and inure to the benefit of the parties hereto
         and their respective successors and permitted assigns, and no other
         Person shall have any right, benefit or obligation under this Agreement
         as a third party beneficiary or otherwise.

                  (g) The parties hereto agree that irreparable damage would
         occur in the event that any of the provisions of this Agreement were
         not performed in accordance with their specific terms. It is
         accordingly agreed that the parties hereto shall be entitled to
         specific performance of the terms hereof, this being in addition to any
         other remedy to which they are entitled at law or in equity.

                  (h) No failure or delay on the part of any party hereto in the
         exercise of any right hereunder shall impair such right or be construed
         to be a waiver of, or acquiescence in, any breach of any
         representation, warranty or agreement herein, nor shall any single or
         partial exercise of any such right preclude other or further exercise
         thereof or of any other right. All rights and remedies existing under
         this Agreement are cumulative to, and not exclusive of, any rights or
         remedies otherwise available.

                  (i) Notwithstanding anything herein to the contrary, no Person
         executing this Agreement who is, or becomes during the term hereof, a
         director of the Company makes any agreement or understanding herein in
         his or her capacity as such director, and the agreements set forth
         herein shall in no way restrict any director in the exercise of his or
         her fiduciary duties as a director of the Company. The Stockholder has
         executed this Agreement solely in his or her capacity as the record or
         beneficial holder of the Stockholder's Shares or as the trustee of a
         trust whose beneficiaries are the beneficial owners of the
         Stockholder's Shares.

                  (j) Each party agrees to bear its own expenses in connection
         with the transactions contemplated hereby.

                  (k) This Agreement shall be governed and construed in

         accordance with the laws of the State of New York, without giving
         effect to any choice of law


                                       12

         or conflict of law provision or rule that would cause the application
         of the laws of any jurisdiction other than the State of New York,
         except to the extent that the General Corporation Law of the State of
         Delaware applies as a result of the Company being incorporated in the
         State of Delaware, in which case such General Corporation Law shall
         apply.

                  (l) EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY
         WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS
         AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT AND
         FOR ANY COUNTERCLAIM THEREIN.

                  (m) This Agreement may be executed in one or more
         counterparts, and by the different parties hereto in separate
         counterparts, each of which when executed shall be deemed to be an
         original but all of which taken together shall constitute one and the
         same agreement.

                    STOCKHOLDER VOTING AND ROLLOVER AGREEMENT

       AGREEMENT, dated as of May 5, 1998, by and between Analog Acquisition

hereto (the "Stockholder"). Capitalized terms used but not defined herein shall
have the meanings set forth in the Agreement and Plan of Merger, dated the date
hereof, by and between Purchaser and ABC (the "Company") (as such agreement may
be amended from time to time, the "Merger Agreement").

       WHEREAS, concurrently herewith, Purchaser and the Company are entering
into a Merger Agreement, pursuant to which Purchaser will be merged with and
into the Company (the "Merger"), whereby each share of common stock, par value
$.01 per share, of the Company ("Company Common Stock") issued and outstanding

receive cash, other than any shares to remain outstanding pursuant to Section
2(g)(iii) of the Merger Agreement and any Dissenting Shares as defined in

       WHEREAS, as a condition to Purchaser's entering into the Merger

Stockholder has agreed to enter into, this Agreement with Purchaser.

       NOW, THEREFORE, in order to implement the foregoing and in consideration
of the mutual agreements contained herein, the parties hereby agree as follows:

         rights, subject to applicable federal securities laws and the terms of
         this Agreement.

         (b) The Stockholder has the legal capacity, power and authority to
       enter into and perform all of the Stockholder's obligations under this
       Agreement. Other than as set forth in Schedule 2(b), the execution,
       delivery and performance of this Agreement by the Stockholder will not
       violate any other agreement to which the Stockholder is a party or by
       which the Stockholder is bound including, without limitation, any trust
       agreement, voting agreement, stockholders agreement, voting trust,
       partnership or other agreement. This Agreement has been duly and validly
       executed and delivered by the Stockholder and constitutes a valid and
       binding agreement of the Stockholder, enforceable against the Stockholder
       in accordance with its terms, except as limited by (a) bankruptcy,
       insolvency, reorganization, moratorium or other similar laws relating to
       creditor's rights generally, (b) general principles of equity, whether
       such enforceability is considered in a proceeding in equity or at law,
       and to the discretion of the court before which any proceeding therefore
       may be brought, or (c) public policy considerations or court decisions
       which may limit the rights of the parties thereto for indemnification.
       All necessary consents of any beneficiary of or holder of interest in any
       trust of which a Stockholder is Trustee to the execution and delivery of
       this Agreement and the

       consummation of the transactions contemplated hereby have been obtained.
       If the Stockholder is married and the Stockholder's Shares constitute
       community property, this Agreement has been duly authorized, executed and
       delivered by, and constitutes a valid and binding agreement of, the
       Stockholder's spouse, enforceable against such person in accordance with
       its terms.


         (c) (i) No filing with, and no permit, authorization, consent or
       approval of, any state or federal public body or authority is necessary
       for the execution of this Agreement by the Stockholder and the
       consummation by the Stockholder of the transactions contemplated hereby
       and (ii) neither the execution and delivery of this Agreement by the
       Stockholder nor the consummation by the Stockholder of the transactions
       contemplated hereby nor compliance by the Stockholder with any of the
       provisions hereof shall (x) conflict with or result in any breach of any
       applicable trust, partnership agreement or other agreements or
       organizational documents applicable to the Stockholder, (y) result in a
       violation or breach of, or constitute (with or without notice or lapse of
       time or both) a default (or give rise to any third party right of
       termination, cancellation, material modification or acceleration) under
       any of the terms, conditions or provisions of any note, bond, mortgage,
       indenture, license, contract, commitment, arrangement, understanding,
       agreement or other instrument or obligation of any kind to which the
       Stockholder is a party or by which the Stockholder or any of the
       Stockholder's properties or assets may be bound or (z) violate any order,
       writ, injunction, decree, judgment, statute, rule or regulation
       applicable to the Stockholder or any of the Stockholder's properties or
       assets.

         (d) Except for the shares of Company Common Stock identified in
       Schedule II hereto (the "Pledged Shares"), the Stockholder's Shares and
       the certificates representing such Shares are now and at all times during
       the term hereof will be held by the Stockholder, or by a nominee or
       custodian for the benefit of the Stockholder, free and clear of all
       liens, claims, security interests, proxies, voting trusts or agreements,
       understandings or arrangements or any other encumbrances whatsoever,
       except for any such encumbrances or proxies arising hereunder.

         (e) No broker, investment banker, financial adviser or other person is
       entitled to any broker's, finder's, financial adviser's or other similar
       fee or commission in connection with the transactions contemplated hereby
       based upon arrangements made by or on behalf of the Stockholder in his or
       her capacity as such.

         (f) The Stockholder understands and acknowledges that Purchaser is
       entering into the Merger Agreement in reliance upon the Stockholder's
       execution and delivery of this Agreement with Purchaser.

       reorganization, moratorium or other similar laws relating to creditor's
       rights generally, (b) general principles of equity, whether such
       enforceability is considered in a proceeding in equity or at law, and to

       Agreement will not, conflict with, or result in any breach or violation
       of, or default (with or without notice or lapse of time, or both) under,

       or "put" right with respect to any obligation or to loss of a material
       benefit under, or result in the creation of any lien upon any of the
       properties or assets of Purchaser under, (i) any charter or by-laws of

       other actions contemplated by the Merger Agreement and this Agreement and
       any actions required in furtherance hereof and thereof; (ii) against any

       any agreement or understanding with any person or entity to vote or give
       instructions in any manner inconsistent with clauses (i) or (ii) of the
       preceding sentence.

       Section 5. Certain Covenants of the Stockholder. Except in accordance
with the terms of this Agreement, the Stockholder hereby covenants and agrees as
follows:


         (a) Prior to the Termination Date, no Stockholder shall, in its
       capacity as such, directly or indirectly (including through advisors,
       agents or other intermediaries), solicit (including by way of furnishing
       information) or respond to any inquiries or the making of any proposal by
       any person or entity (other than Purchaser or any Affiliate thereof) with
       respect to the Company that constitutes or could reasonably be expected
       to lead to an Acquisition Proposal. If the Stockholder in its capacity as
       such receives any such inquiry or proposal, then the Stockholder shall
       within 24 hours furnish Purchaser with an accurate description of the
       material terms (including any changes or adjustments to such terms as a
       result of negotiations or otherwise) and conditions, if any, of such
       inquiry or proposal and the identity of the person making it. The
       Stockholder, in its capacity as such, will immediately cease and cause to
       be terminated any existing activities, discussions or negotiations with
       any parties conducted heretofore with respect to any of the foregoing;
       provided, that the limitation set forth in this sentence shall not
       restrict the Stockholder from engaging in any such activities with such a
       third party who hereafter makes a Superior Acquisition Proposal. The
       foregoing provisions of this Section 5(a) shall not restrict a
       Stockholder who is also a director of the Company from taking any
       actions, or refraining from complying with the foregoing provision, in
       the Stockholder's capacity as a director, provided that any such actions
       do not violate Section 5(k) of the Merger Agreement.

         (b) Prior to the Termination Date, the Stockholder shall not, directly
       or indirectly (i) except pursuant to the terms of the Merger Agreement or
       this Agreement, offer for sale, sell, transfer, tender, pledge, encumber,
       assign or otherwise dispose of, enforce or permit the execution of the
       provisions of any redemption agreement with the Company or enter into any
       contract, option or other arrangement or understanding with respect to or
       consent to the offer for sale, sale, transfer, tender, pledge,
       encumbrance, assignment or other disposition of, or exercise any
       discretionary powers to distribute, any or all of the Stockholder's
       Shares or any interest therein, including any trust income or principal,
       except in each case to a Permitted Transferee who is or agrees to become
       bound by this Agreement; (ii) except as contemplated hereby, grant any
       proxies or powers of attorney with respect to any Shares, deposit any
       Shares into a voting trust or enter into a voting agreement with respect
       to any Shares; or (iii) take any action that would make any
       representation or warranty of the Stockholder contained herein untrue or
       incorrect or have the effect of preventing or disabling the Stockholder
       from performing the Stockholder's obligations under this Agreement.


                                       8
<PAGE>



         (c) The Stockholder hereby waives any rights of appraisal or rights to
       dissent from the Merger that the Stockholder may have. The Trustee
       represents that no beneficiary who is a beneficial owner of Shares under
       any trust has any right of appraisal or right to dissent from the Merger
       which has not been so waived.


         (d) (i) Subject to the terms and provisions of the Merger Agreement, in
       connection with the Merger, the Stockholder hereby agrees to retain an
       aggregate of 26,250 shares of Surviving Corporation Class A Common Stock
       held by and registered in the name of the Stockholder, and in the amount
       opposite such name, set forth on Schedule III hereto, upon conversion of,
       and with respect to, 26,250 of such Stockholder's Shares (the "Rollover
       Shares") unless otherwise agreed with Purchaser.

                  (ii) The Stockholder shall use its best efforts to negotiate
       and execute an Investors Agreement on terms and conditions mutually
       satisfactory to Purchaser and Stockholder.

         (e) Unless, in connection therewith, the Shares held by any trust which
       are presently subject to the terms of this Agreement are transferred to
       the Stockholder and remain subject in all respects to the terms of this
       Agreement, or other Permitted Transferees who upon receipt of such Shares
       become signatories to this Agreement, the Stockholder who is a Trustee
       shall not take any action to terminate, close or liquidate any such trust
       and shall take all steps necessary to maintain the existence thereof at
       least until the first to occur of (i) the Effective Time and (ii) the
       Termination Date.

         (f) The Stockholder shall take all actions necessary to cause any
       Rollover Shares that constitute Pledged Shares, prior to the Effective
       Time, to be free and clear of all liens, claims, security interests,
       proxies, voting trusts or agreements, understandings or arrangements or
       any other encumbrances whatsoever, except for any such encumbrances or
       proxies arising hereunder.

       Section 6. Further Assurances. From time to time, at the other party's
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further action as may be
necessary or desirable to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement.

       Section 7. Certain Events. The Stockholder agrees that this Agreement and
the obligations hereunder shall attach to the Stockholder's Shares and shall be
binding



                                       9
<PAGE>



upon any person or entity to which legal or Beneficial Ownership of such Shares
shall pass, whether by operation of law or otherwise, including without
limitation the Stockholder's heirs, guardians, administrators or successors or
as a result of any divorce.

       Section 8. Stop Transfer. The Stockholder agrees with, and covenants to,
Purchaser that the Stockholder shall not request that the Company register the

transfer (book-entry or otherwise) of any certificate or uncertificated interest
representing any of the Stockholder's Shares, unless such transfer is made in
compliance with this Agreement.

       Section 9. Rule 145 Affiliates. The Stockholder who is an "affiliate" of
the Company for purposes of Rule 145 under the Securities Act of 1933, as
amended, hereby agrees to deliver to Purchaser, on or prior to the Effective
Time, a written agreement in form and substance acceptable to Purchaser,
restricting the disposition of Rollover Shares.

       Section 10. Termination. The obligations of the Stockholder and the
irrevocable proxy contained in Section 4(b) of this Agreement shall terminate
upon the first to occur of (a) the Effective Time and (b) the date the Merger
Agreement is terminated in accordance with its terms (the "Termination Date");
provided that the provisions of Sections 2, 3, 10 and 11 and any claim for
breach of any representation, warranty, covenant or other agreement under this
Agreement shall survive the Effective Time and/or the Termination Date, as
applicable.

       Section 11. Miscellaneous.

         (a) Notices. All notices, requests, demands and other communications
       under this Agreement shall be in writing and shall be deemed to have been
       duly given (i) on the day of service if served personally on the party to

         (e) This Agreement, including all exhibits, disclosure schedules and
       schedules hereto, constitutes the entire agreement and supersedes all
       prior agreements and undertakings, both written and oral, among the
       parties, or any of them, with respect to the subject matter hereof and
       except as otherwise expressly provided herein.

         (f) Neither this Agreement nor any of the rights or obligations
       hereunder may be assigned by any party (whether by operation of law or
       otherwise) without the prior written consent of the other parties hereto.
       Subject to the preceding sentence, this Agreement shall be binding upon
       and inure to the benefit of the parties hereto and their respective
       successors and permitted assigns, and no other Person shall have any

       right, benefit or obligation under this Agreement as a third party
       beneficiary or otherwise.

         (g) The parties hereto agree that irreparable damage would occur in the
       event that any of the provisions of this Agreement were not performed in
       accordance with their specific terms. It is accordingly agreed that the
       parties hereto shall be entitled to specific performance of the terms
       hereof, this being in addition to any other remedy to which they are
       entitled at law or in equity.

         (h) No failure or delay on the part of any party hereto in the exercise
       of any right hereunder shall impair such right or be construed to be a
       waiver of, or acquiescence in, any breach of any representation, warranty
       or agreement herein, nor shall any single or partial exercise of any such
       right preclude other or further exercise thereof or of any other right.
       All rights and remedies existing under this Agreement are cumulative to,
       and not exclusive of, any rights or remedies otherwise available.

         (i) Notwithstanding anything herein to the contrary, no Person
       executing this Agreement who is, or becomes during the term hereof, a
       director of the Company makes any agreement or understanding herein in
       his or her capacity as such director, and the agreements set forth herein
       shall in no way restrict any director in the exercise of his or her
       fiduciary duties as a director of the Company. The Stockholder has
       executed this Agreement solely in his or her capacity as the record or
       beneficial holder of the Stockholder's Shares or as the trustee of a
       trust whose beneficiaries are the beneficial owners of the Stockholder's
       Shares.

         (j) Each party agrees to bear its own expenses in connection with the
       transactions contemplated hereby.

         (k) This Agreement shall be governed and construed in accordance with
       the laws of the State of New York, without giving effect to any choice of
       law or conflict of law provision or rule that would cause the application
