Dear Shareholder:
 
    The Board of Directors of Vaughn Communications, Inc. ("Vaughn") has
approved a merger in which the Company and Twin Acquisition Corp. ("TAC") will
merge, with Vaughn being the surviving corporation (the "Merger").
 
    The Board of Directors of Vaughn and a special committee of Vaughn's
independent, non-employee directors (the "Special Committee") determined that
the right to receive $10.00 in cash for each share of Vaughn common stock is
fair to Vaughn shareholders and is in the best interests of Vaughn shareholders.
The Board of Directors of Vaughn and the Special Committee recommend that
shareholders vote in favor of the Merger. Certain members of Vaughn's Board of
Directors have interests in the Merger that may conflict with the interests of
Vaughn shareholders generally. See "Special Factors--Conflicts of Interest" in
the attached proxy statement (the "Proxy Statement").
 
    You are cordially invited to attend a special meeting of Vaughn shareholders
(the "Special Meeting") to vote whether to approve and adopt the Merger in
accordance with the Agreement and Plan of Merger, dated as of December 11, 1998,
among Vaughn, TAC and, only for purposes of Section 8.11 thereof, Allied
Digital, Inc., parent of TAC.
 
YOUR VOTE IS VERY IMPORTANT
 
    Whether or not you plan to attend the Special Meeting, please take the time
to vote on the proposal submitted by completing and mailing the enclosed proxy
card to us. Please sign, date and mail your proxy card indicating how you wish
to vote. If you fail to return your proxy card, the effect will be a vote
against the Merger.
 
    The date, time and place for the Special Meeting is:
 
    - February 23, 1999, at 10:00 a.m., local time
 
    - at Vaughn Communications, Inc.
     7951 Computer Avenue
     Minneapolis, Minnesota 55435
 
    The enclosed Proxy Statement provides you with detailed information about
the Merger. In addition, you may obtain information about Vaughn from documents
filed with the Securities and Exchange Commission. We encourage you to read this
entire document carefully.
 
                                        Sincerely,
 
                                        /s/ E. David Willette
 
                                        E. David Willette
                                        CHIEF EXECUTIVE OFFICER

________________________________________________________________________________
 
To the Shareholders of Vaughn Communications, Inc.:
 
    Notice is hereby given that a special meeting of the shareholders (the
"Special Meeting") of Vaughn Communications, Inc. ("Vaughn" or the "Company")
will be held at the offices of Vaughn Communications, Inc., 7951 Computer
Avenue, Minneapolis, Minnesota 55435 on February 23, 1999, at 10:00 a.m. local
time, for the following purposes:
 
1.  To consider and vote upon a proposal recommended by the Board of Directors
    of Vaughn and a special committee of Vaughn's independent non-employee
    directors to approve and adopt a plan of merger in accordance with the
    Agreement and Plan of Merger, dated as of December 11, 1998 (the "Merger
    Agreement"), among Vaughn, Twin Acquisition Corp. ("TAC"), a Minnesota
    corporation, and, only for purposes of Section 8.11 thereof, Allied Digital,

    Vaughn (the "Merger"), with Vaughn being the surviving corporation and (ii)

    their dissenters' rights under Minnesota law) will become entitled to
    receive $10.00 in cash (the "Merger Consideration") for each outstanding
    share of Vaughn common stock, par value $.10 per share (the "Vaughn Common
    Stock"), owned immediately prior to the effective date of the Merger. A copy
    of the Merger Agreement is attached as Annex A to the accompanying proxy
    statement (the "Proxy Statement"). The Merger Agreement is also described in
    the attached Proxy Statement.
 
2.  To act upon such other matters as may properly come before the Special
    Meeting or any adjournment(s) or postponement(s) of the Special Meeting.
 
    The Board of Directors of the Company has fixed the close of business on
January 20, 1999 as the record date for determination of shareholders entitled
to notice of, and to vote at, the Special Meeting and any adjournment(s) and
postponement(s) of the Special Meeting. A complete list of the shareholders
entitled to vote at the Special Meeting or any adjournments or postponements of
the Special Meeting will be available at and during the Special Meeting.

    - delivering to Vaughn prior to the vote at the Special Meeting a duly
      executed proxy with a later date than your original proxy, or
 
    - giving written notice of revocation to Vaughn addressed to Mr. M. Charles
      Reinhart, Secretary, Vaughn Communications, Inc., 5050 West 78th Street,
      Minneapolis, Minnesota 55435 prior to the vote at the Special Meeting.
 
    If you return a proxy without specifying a choice on the proxy, the proxy
will be voted "FOR" the Merger. Further information regarding the Special
Meeting is in the attached Proxy Statement.
 
    Under Minnesota law, holders of shares of Vaughn Common Stock have the right
to dissent from the Merger and to receive payment of the fair value of their
shares upon compliance with the Minnesota Business Corporation Act (the "MBCA").
This right is explained more fully under "The Merger--
<PAGE>
Dissenters' Rights" in the accompanying Proxy Statement. The dissenters' rights
provisions of the MBCA are attached to the Proxy Statement as Annex C.
 
    You are cordially invited to attend the Special Meeting. However, whether or
not you expect to attend the Special Meeting in person, please complete, sign,
date and return the accompanying proxy without delay in the enclosed postage
prepaid envelope. The proxy is revocable and will not be used if you are present

shares registered in different names, or at different addresses, sign and return
each proxy card.
 
                                        By order of the Board of Directors,
 
                                        /s/ E. David Willette

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
WHY SHOULD VAUGHN MERGE WITH TAC?
 
    For shareholders of Vaughn Communications, Inc. ("Vaughn"), the Merger (as
defined in this Proxy Statement) provides cash for their shares of common stock
of Vaughn, par value $.10 per share (the "Vaughn Common Stock"), at a premium of
approximately 27% over the average closing price for the four-week period
immediately preceding the date that Vaughn first made any public announcement
regarding the Merger. The Board of Directors and a special committee, comprised
of independent, non-employee directors of Vaughn (the "Special Committee"), have
determined that the Merger and the consideration to be received is fair to, and
is in the best interests of, the shareholders of the Company. See "Special
Factors--Reasons for the Merger and Recommendation of the Board of Directors."
Certain members of Vaughn's Board of Directors have interests in the Merger that
generally may be considered in conflict with the interests of Vaughn
shareholders generally. See "Special Factors--Conflicts of Interest."
 
WHO IS TAC?
 
    Twin Acquisition Corp. ("TAC") is a Minnesota corporation and wholly-owned
subsidiary of Allied Digital, Inc. ("ADI"), formed for the purpose of merging
with and into Vaughn.
 
WHAT WILL BE RECEIVED IN EXCHANGE FOR VAUGHN COMMON STOCK?
 
    Other than shares owned by shareholders who have demanded dissenters' rights
and satisfied the procedures relating to dissenters' rights, each share of
Vaughn Common Stock will be converted automatically into the right to receive
$10.00 per share, without interest. See "The Merger--Ownership of Capital
Stock."
 
WHERE AND WHEN IS THE SPECIAL MEETING?
 
    The Special Meeting (as defined in this Proxy Statement) of Vaughn
shareholders and adjournments of the Special Meeting will be held at 10:00 a.m.,
local time, on February 23, 1999, at the offices of Vaughn Communications, Inc.,
7951 Computer Avenue, Minneapolis, Minnesota 55435 (the "Special Meeting").
 
HOW WILL I BE TAXED ON THE MERGER?
 
    For U.S. Federal income tax purposes, the receipt of cash by holders of
Vaughn Common Stock will be a taxable transaction. All shareholders are urged to
consult their tax advisors to determine the effect of the Merger under federal
tax law (or foreign tax law where applicable), and under their own state and
local tax laws. See "Special Factors--Certain Federal Income Tax Consequences."
 
WHAT WILL HAPPEN TO VAUGHN AFTER THE MERGER?
 
    After the Merger, Vaughn Common Stock will no longer be publicly traded and
members of the general public will therefore no longer have the opportunity to
participate in its future earnings and growth. Vaughn will be an indirect
wholly-owned subsidiary of Allied Digital Technologies Corp., a Delaware
corporation ("Allied"). After the Merger, shares of Vaughn Common Stock will no
longer be quoted on the Nasdaq National Market System ("Nasdaq"). See
"Information Concerning Vaughn Common Stock." Shortly after the Merger, it is
anticipated that Vaughn will be reincorporated in Delaware.
 
ARE THERE RISKS TO BE CONSIDERED?
 
    The cash consideration of $10.00 for each share of Vaughn Common Stock will
not change even if the market price of Vaughn Common Stock changes before the
Merger is completed. For other factors to consider, see "Information Concerning
Vaughn Common Stock."
 
                                       1
<PAGE>
ARE VAUGHN SHAREHOLDERS ENTITLED TO DISSENTERS' RIGHTS?
 
    Yes. Under the Minnesota Business Corporation Act ("MBCA"), Vaughn
shareholders are entitled to dissenters' rights. The rules governing the
exercise of dissenters' rights must be strictly complied with, otherwise a
shareholder's dissenters' rights may be lost. For a description of these rights
and how to satisfy the requirements of the MBCA, see "The Merger--Dissenters'
Rights" and Annex C.
 
WHO CAN VOTE AT THE SPECIAL MEETING?
 
    Holders of Vaughn Common Stock at the close of business on January 20, 1999
(the "Record Date") may vote at the Special Meeting. Each share of Vaughn Common
Stock is entitled to one vote.
 
WHAT VOTE IS REQUIRED?
 
    The Merger must be approved by the holders of a majority of the shares of
Vaughn Common Stock outstanding on the Record Date. On the Record Date, there
were 4,107,058 shares of Vaughn Common Stock outstanding.
 
WHAT WILL HAPPEN TO VAUGHN COMMON STOCK OPTIONS TO PURCHASE VAUGHN COMMON STOCK
AND ARE MANAGEMENT SHAREHOLDERS TREATED DIFFERENTLY FROM OTHER SHAREHOLDERS?
 
    Each option to purchase Vaughn Common Stock outstanding immediately prior to
the filing of a certificate of merger with the Secretary of State of the State
of Minnesota (the "Effective Time") (whether or not such option is vested or
exercisable) will be canceled. Other than pursuant to the Option Termination and
Grant Agreement, dated December 11, 1998 (the "Willette Option Termination and
Grant Agreement") among the Company, Allied and E. David Willette ("Willette"),
attached hereto as Annex D and incorporated herein by reference, each holder of
an option that is canceled will receive a cash payment equal to the product of
(a) the excess of the cash consideration in the Merger over the exercise price
of the option multiplied by (b) the number of shares subject to the option, less
any applicable withholding taxes. See "Interests of Certain Persons in the
Merger--Willette Option Termination and Grant Agreement; --Treatment of
Options." Current shareholders in Vaughn will not continue their equity interest
in Vaughn following the Merger or share in any future earnings or the potential
growth of Vaughn.
 
IF MY SHARES OF VAUGHN COMMON STOCK ARE HELD IN "STREETNAME" BY MY BROKER, WILL
MY BROKER VOTE MY SHARES FOR ME?
 
    No. The law does not allow your broker to vote your shares of Vaughn Common
Stock on the Merger at the Special Meeting without your direction. You should
follow the instructions from your broker on how to vote your shares. Shares that
are not voted because you do not instruct your broker are called "broker
non-votes," and will have the effect of a vote "AGAINST" the Merger.
 
IF I SEND IN MY PROXY CARD BUT FORGET TO INDICATE MY VOTE, HOW WILL MY SHARES BE
VOTED?
 
    If you sign and return your proxy card but do not indicate how to vote your
shares at the Special Meeting, the shares represented by your proxy will be
voted "FOR" the Merger.
 
WHAT SHOULD I DO NOW TO VOTE AT THE SPECIAL MEETING?
 
    Sign, mark and mail your proxy card indicating your vote on the Merger in
the enclosed return envelope as soon as possible, so that your shares of Vaughn
Common Stock can be voted at the Special Meeting.

<PAGE>
MAY I CHANGE MY VOTE AFTER I MAIL MY PROXY CARD?
 
    Yes. You may change your vote at any time before your proxy is voted at the
Special Meeting. You can do this in three ways:
 
    - You can send Vaughn a written statement that you revoke your proxy, which
      to be effective must be received by Vaughn at its executive offices prior
      to the vote at the Special Meeting; or
 
    - You can send Vaughn a new proxy card prior to the vote at the Special
      Meeting, which to be effective must be received by Vaughn prior to the
      vote at the Special Meeting; or
 
    - You can attend the Special Meeting and vote in person. Your attendance
      alone will not revoke your proxy. You must attend the Special Meeting and
      cast your vote at the Special Meeting.
 
    You should send your revocation of a proxy or new proxy card to the
Secretary of Vaughn at the address on the cover of this Proxy Statement. If your
shares are held by a broker, you must follow the directions provided by your
broker to vote your shares or to change your instructions.
 
DO I SEND IN MY STOCK CERTIFICATES NOW?
 
    No. If the Merger is completed, you will receive written instructions for
delivering your stock certificates representing Vaughn Common Stock in order to
receive $10.00 per share cash consideration in the Merger from American Stock
Transfer & Trust Company ("AST"), who has been appointed as paying agent in
connection with the Merger. DO NOT SEND YOUR STOCK CERTIFICATES NOW.

                                    ("Allied"), is the sole shareholder of TAC. The

THE MERGER AND THE SPECIAL MEETING
 
Reasons for the Merger............  The Company believes that it cannot access the necessary
                                    capital to execute its growth strategy on a stand-alone
                                    basis given the current conditions in the public equity
                                    market. The Company's business strategy of growing its
                                    business-to-business video duplication sales through
                                    acquisitions and new facility openings, and expanding
                                    its product offering to existing customers by
                                    introducing newer multi-media technologies (such as
                                    compact disc ("CD") replication) requires substantial
                                    capital. Lack of appreciation in the per share price of
                                    Vaughn Common Stock due to a number of factors has
                                    limited the Company's ability to raise capital through
                                    the public markets. The Board of Directors and the
                                    special committee to the Vaughn Board of Directors (the
                                    "Special Committee") believe that it is fair to, and in
                                    the best interests of, Vaughn shareholders to accept
                                    $10.00 in cash for their shares, a price determined by
                                    the financial advisor to the Special Committee to be
                                    fair to Vaughn's shareholders and a

                                    27% premium over the average closing price of Vaughn
                                    Common Stock for the four-week period immediately
                                    preceding the date on which Vaughn first publicly
                                    announced the Merger. See "Special Factors--Background
                                    of the Merger" and "Special Factors--Reasons for the
                                    Merger and Recommendation of the Board of Directors."
 
Recommendation of the Special
  Committee and Board of
  Directors.......................  The Special Committee, comprised of independent, non-
                                    employee directors of Vaughn, and the Board of Directors
                                    of Vaughn have unanimously approved the Merger and
                                    recommended that Vaughn shareholders vote "FOR" the
                                    proposal to approve the Merger. See "Special Factors--
                                    Background of the Merger" and "Special Factors--Reasons
                                    for the Merger and Recommendation of the Board of
                                    Directors." Certain members of Vaughn's Board of
                                    Directors have interests in the Merger that generally
                                    may be considered in conflict with the interests of
                                    Vaughn shareholders. See "Special Factors-- Conflicts of
                                    Interest." The members of the Special Committee received
                                    certain compensation in consideration of their services
                                    as members of the Special Committee. See "Interests of
                                    Certain Persons in the Merger--Fees Payable to the
                                    Special Committee and Financial Advisor."

                                    Meeting will be held at the offices of Vaughn
                                    Communications, Inc., 7951 Computer Avenue, Minneapolis,

                                    assumption of outstanding indebtedness of Vaughn of

                                    than pursuant to the Willette Option Termination and

                                    Merger over the exercise price of the option multiplied
                                    by (b) the number of shares subject to the option, less
                                    any applicable withholding taxes. See "Interests of

                                    It is anticipated that neither TAC nor Vaughn will

                                    immediately following the Effective Time. Under the
                                    terms of existing employment agreements with each of
                                    Donald J. Drapeau and M. Charles Reinhart, each such

                                    Reinhart on the date one year after the consummation of

                                    Agreement, the obligation of TAC to merge with and into
                                    Vaughn is subject to the condition, which may be waived
                                    by TAC, that holders of no more than 10% of the
                                    outstanding shares of Vaughn Common Stock exercise
                                    dissenters' rights in accordance with the MBCA. See "The
                                    Merger--Dissenters' Rights" and Annex C.

                                    applicable. These conditions include:
 
                                        - Vaughn shareholders holding a majority of the
                                          outstanding Vaughn Common Stock approve the

Superior Acquisition Proposals and
  Termination Fee.................  Vaughn may accept another offer under certain
                                    circumstances. However, Vaughn must pay TAC $1.9
                                    million, and reimburse TAC for its reasonable
                                    out-of-pocket expenses up to a maximum amount of
                                    $900,000, if the Merger Agreement is terminated in the
                                    event that:

                                        has determined, in good faith, and after

                                          advisors, that another acquisition proposal is
                                          reasonably likely to be subject to completion and,
                                          if consummated, is more favorable from a financial
                                          point of view than the Merger ("Superior
                                          Acquisition Proposal");

                                        warranty, covenant, agreement or other obligation

                                          months of the termination of the Merger Agreement

                                          thereof, Vaughn consummates any Transaction
                                          Proposal (whether or not proposed prior to the

                                          months of the termination of the Merger Agreement
                                          by TAC pursuant to the terms and conditions
                                          thereof, Vaughn consummates any Transaction
                                          Proposal (whether or not proposed prior to the

                                    See "The Merger Agreement--Termination."
 
Amending or Waiving Terms of the
  Merger Agreement................  Vaughn and TAC may amend the Merger Agreement by mutual
                                    consent before or after Vaughn's shareholders vote on
                                    the Merger. After Vaughn's shareholders approve the
                                    Merger, applicable law may require that subsequent
                                    amendments be approved by Vaughn shareholders. Either
                                    Vaughn or TAC may waive a right to withdraw from the
                                    Merger in circumstances that, under the Merger
                                    Agreement, would allow them to withdraw from the Merger.
 
Federal Income Tax Consequences...  The receipt of cash by holders of Vaughn Common Stock
                                    will be a taxable transaction. All shareholders are
                                    urged to consult their own tax advisors to determine the
                                    effect of the Merger on the shareholder under federal
                                    law, and under their own state and local tax laws. See
                                    "Special Factors--Certain Federal Income Tax
                                    Consequences."
 
Regulatory and Third-Party
  Approvals.......................  Other than compliance with the Hart-Scott-Rodino
                                    Antitrust Improvements Act of 1976, there are no
                                    material regulatory approvals required. Failure to

                                    that, as a condition to the Merger, which may be waived
                                    by TAC, Vaughn is obligated to obtain the consents of
                                    various third parties, if necessary, who are parties to
                                    contracts with Vaughn. See "The Merger--Regulatory
                                    Requirements."

                                    Merger Agreement is fair, from a financial point of
                                    view, to holders of Vaughn Common Stock. The full text

                                    assumptions made, the matters considered, the scope and

                                    followed by EVEREN in rendering such opinion, is

    The Company has not paid dividends on Vaughn Common Stock during the fiscal
years ended January 31, 1998 and 1997. The payment of dividends, if any, will be
contingent upon the Company's revenues and earnings, if any, capital
requirements and general financial condition. It is the current policy of the
Company's Board of Directors, in view of the Company's contemplated financial
requirements, to retain all earnings, if any, for use in the Company's business
operations.
 
    On December 10, 1998, the calendar day before the public announcement of
entering into the Merger, the high and low sales prices for the Vaughn Common
Stock were $8.25 and $8.00, respectively, as quoted on Nasdaq. The closing sales
price for Vaughn Common Stock on December 10, 1998 was $8.25 per share. The
closing price of Vaughn Common Stock on January 29, 1999, which was the last
trading day for which a closing sales price was available before this Proxy
Statement was mailed, was $9 3/4 per share.
 
                              THE SPECIAL MEETING
 
    Throughout this Proxy Statement the term "Merger" means the merger between
TAC and Vaughn, with Vaughn being the Surviving Corporation. The term "Merger
Agreement" means the Agreement and Plan of Merger dated as of December 11, 1998,
among Vaughn, TAC and ADI (only for purposes of Section 8.11 thereof). A copy of
the Merger Agreement is attached as Annex A to this Proxy Statement.
 
DATE, PLACE, TIME AND PURPOSE
 
    This Proxy Statement (the "Proxy Statement") is being furnished to Vaughn
shareholders in connection with the solicitation of proxies by the Board of
Directors of Vaughn for use at the Special Meeting to be held at the offices of
Vaughn Communications, Inc., 7951 Computer Avenue, Minneapolis, Minnesota 55435,
on February 23, 1999 at 10:00 a.m. local time, and any adjournments and
postponements of the Special Meeting. At the Special Meeting, holders of record
as of the close of business on the Record Date of Vaughn Common Stock will be
eligible to vote upon the recommendation of Vaughn's Board of Directors to
approve and adopt a plan of merger in accordance with the Merger Agreement,
pursuant to which (i) TAC will be merged with and into Vaughn, with Vaughn being
the Surviving Corporation, and
 
                                       11
<PAGE>
(ii) each outstanding share of Vaughn Common Stock will be canceled and
converted automatically into the right to receive $10.00 in cash, payable to the
holder of such share, without interest, other than shares of Vaughn Common Stock
held by shareholders who are entitled to, and who have perfected, their
dissenters' rights. See "The Merger--Dissenters' Rights" for further
information.
 
    This Proxy Statement and the accompanying form of proxy are first being
mailed on or about February 1, 1999, to all shareholders of record as of the
Record Date (as defined below).
 
MATTERS TO BE CONSIDERED AT THE MEETING; EFFECT OF APPROVAL OF MERGER AGREEMENT
 
    At the Special Meeting, holders of Vaughn Common Stock as of the Record Date
will be asked to consider and vote upon a proposal to approve and adopt the
Merger Agreement.
 
    Pursuant to the MBCA, a plan of merger involving a Minnesota corporation
must initially be approved by the affirmative vote of a majority of the board of
directors of such corporation prior to submission of such plan to such
corporation's shareholders. In addition, the Articles of Incorporation, as
amended and restated, of the Company provide that a plan of merger must be
submitted to the shareholders after approval by the Board of Directors. In
accordance therewith, the Board of Directors of the Company has unanimously
approved the Merger Agreement and has directed that it be submitted to the
shareholders for their approval in accordance with the MBCA and the Articles of
Incorporation of the Company, as amended and restated.
 
    The Board of Directors and the Special Committee have approved the Merger
Agreement and recommend that the shareholders vote "FOR" approval and adoption
of the Merger Agreement.
 
RECORD DATE; VOTING AT THE MEETING
 
    The Board of Directors has fixed the close of business on January 20, 1999
as the record date (the "Record Date") for the determination of the shareholders
entitled to notice of, and to vote, at the Special Meeting and any adjournments
and postponements of the Special Meeting. On the Record Date, there were
4,107,058 shares of Vaughn Common Stock outstanding, which shares were held by
approximately 295 holders of record. Shares of Vaughn Common Stock are the only
authorized and outstanding voting securities of the Company. Each holder of
record of Vaughn Common Stock as of the Record Date is entitled to cast one vote
per share, exercisable in person or by properly executed proxy, upon each matter
properly submitted for the vote of the shareholders at the Special Meeting.
Votes at the Special Meeting will be tabulated by an Inspector of Election
appointed by Vaughn.
 
    A majority of the shares of Vaughn Common Stock issued and outstanding and
entitled to vote, present in person or represented by proxy, will constitute a
quorum for the transaction of business at the Special Meeting. If a quorum
should not be present, the Special Meeting may be adjourned from time to time,
until a quorum is present. Abstentions and broker non-votes are counted for
purposes of determining the presence of a quorum at the Special Meeting for the
transaction of business.
 
    The Vaughn Board of Directors and the Special Committee have determined that
the right to receive $10.00 in cash for each share of Vaughn Common Stock is
fair to, and in the best interests of, all of Vaughn shareholders. However, any
holder of record of shares of Vaughn Common Stock as of the Record Date who,
prior to the vote on the Merger at the Special Meeting, makes a written demand
by following the procedures prescribed by Sections 302A.471 and 302A.473 of the
MBCA, has the right to payment of the "fair value" of such shares by Vaughn, as
the Surviving Corporation in the Merger, in lieu of receiving the consideration
provided under the Merger Agreement (the "Dissenters' Rights"). A summary of the
procedures relating to the exercise of Dissenters' Rights under the MBCA is
included in this Proxy Statement under "The Merger--Dissenters' Rights" and the
full text of Sections 302A.471 and 302A.473 of the MBCA is included as Annex C
hereto. The obligation of TAC to merge with and into Vaughn is subject to the
condition, which may be waived by TAC, that holders of no more than 10% of the
outstanding shares of Vaughn Common Stock satisfy the MBCA's procedures to
properly exercise and perfect Dissenters' Rights under the MBCA. See "The
Merger--Dissenters' Rights."
 
                                       12
<PAGE>
VOTE REQUIRED
 
    Approval of the principal terms of the Merger Agreement requires the
affirmative vote of holders of a majority of the outstanding shares of Vaughn
Common Stock entitled to vote at the Special Meeting under the MBCA and Vaughn's
Articles of Incorporation, as amended and restated. A failure to vote, an
abstention from voting, or a broker non-vote, will have the same legal effect as
a vote cast against approval of the Merger and the Merger Agreement. Brokers,
and in many cases nominees, will not have discretionary power to vote on the
proposals to be presented at the Special Meeting. Accordingly, beneficial owners
of shares must instruct their brokers or nominees how to vote their shares at
the Special Meeting.
 
SOLICITATION, REVOCATION AND USE OF PROXIES
 
    Vaughn will bear all expenses of the solicitation of proxies in connection
with this Proxy Statement, including the cost of preparing and mailing this
Proxy Statement. Vaughn will reimburse brokers, fiduciaries, custodians and
other nominees for reasonable out-of-pocket expenses incurred in sending this
Proxy Statement and other proxy materials to, and obtaining instructions
relating to such materials from, beneficial owners of Vaughn Common Stock.
Vaughn shareholder proxies may be solicited by directors, officers and employees
of the Company in person or by telephone, facsimile or by other means of
communication. Vaughn will also reimburse custodians, nominees and fiduciaries
for forwarding proxies and proxy materials to beneficial owners of their stock
in accordance with the rules and regulations of the Securities and Exchange
Commission (the "SEC").
 
    A shareholder giving a proxy has the power to revoke it at any time before
it is exercised by (i) filing with the Secretary of Vaughn written notice
revoking it before the vote at the Special Meeting; (ii) executing a proxy with
a later date; or (iii) attending the Special Meeting and voting in person at the
Special Meeting. Any written notice of revocation should be delivered to Vaughn
Communications, Inc., 5050 West 78th Street, Minneapolis, Minnesota 55435,
Attention: Secretary. Subject to proper revocation, all shares of Vaughn Common
Stock represented at the Special Meeting by properly executed proxies received
by Vaughn will be voted in accordance with the instructions contained in such
proxies. Executed but unmarked proxies will be voted "FOR" the approval of the
Merger.
 
SURRENDER OF SHARE CERTIFICATES
 
    AST has been designated to act as paying agent for the benefit of holders of
shares of Vaughn Common Stock in connection with the Merger and as such will
receive the $10.00 per share cash consideration to which holders of shares will
become entitled. TAC will deposit with AST the funds required in order to pay
the Merger Consideration. Such funds will be invested by AST as directed by the
Surviving Corporation and any interest and other income resulting from such
investment will be paid to the Surviving Corporation.
 
    Promptly after the date on which the transactions contemplated by the Merger
Agreement are consummated (the "Closing Date"), AST will send to each holder of
shares of Vaughn Common Stock outstanding, immediately prior to the Effective
Time, a letter of transmittal (the "Letter of Transmittal") and instructions for
use in effecting the surrender of certificates. The Letter of Transmittal will
specify that the delivery will be effected, and risk of loss and title will
pass, only upon delivery of the certificates representing shares of Vaughn
Common Stock to AST. AST will receive a fee which Vaughn expects will not exceed
$12,500 as compensation for its services, plus reimbursement of its
out-of-pocket expenses in connection with such services. Vaughn has agreed to
indemnify AST against certain liabilities arising out of or in connection with
its engagement.
 
    Each holder of a share of Vaughn Common Stock that has been converted into
the right to receive the cash consideration in the Merger, upon surrender to AST
of a certificate or certificates representing such shares, together with a
properly completed Letter of Transmittal covering such shares, will be entitled
to receive the cash consideration payable in respect of such shares. Until so
surrendered, each such certificate
 
                                       13
<PAGE>
will, after the Effective Time, represent for all purposes, only the right to
receive such cash consideration. No interest will be paid or will accrue on any
cash payable as cash consideration in the Merger.
 
    If any portion of the cash consideration is to be paid to a person other
than the registered holder of the shares of Vaughn Common Stock represented by
the certificate or certificates surrendered in exchange therefor, it will be a
condition to such payment that the certificate or certificates so surrendered be
properly endorsed or otherwise be in proper form for transfer and that the
person requesting such payment will pay to AST any transfer or other taxes
required as a result of such payment to a person other than the registered
holder of such shares or establish to the satisfaction of the Surviving
Corporation or AST that such tax has been paid or is not applicable.
 
    At any time following the sixth month after the Effective Time, the
Surviving Corporation will be entitled to require AST to deliver to it the funds
made available to AST and not disbursed to holders of Vaughn Common Stock, and
thereafter such holders will be entitled to look to the Surviving Corporation
only as general creditors thereof for payment of their claim for cash.
Notwithstanding the foregoing, to the fullest extent permitted by law, neither
the Surviving Corporation nor AST will be liable to any holder of a share of
Vaughn Common Stock or to any other person for any Merger Consideration (as
defined in this Proxy Statement) delivered in respect of such share to a public
official pursuant to any applicable abandoned property, escheat or similar law.
 
    If any certificates representing shares of Vaughn Common Stock have not been
surrendered before the fifth anniversary of the Effective Time, any cash in
respect of such certificates will, to the extent permitted by applicable law,
become the property of the Surviving Corporation. In addition, if any cash in
respect of certificates representing shares of Vaughn Common Stock would, prior
to the fifth anniversary of the Effective Time, otherwise escheat to or become
the property of a governmental entity, such cash will, to the extent permitted
by applicable law, become the property of the Surviving Corporation.
 
    At and after the Effective Time, there will be no further registration of
transfers of Vaughn Common Stock on the records of Vaughn or its transfer agent.
From and after the Effective Time, the holders of Vaughn Common Stock
outstanding immediately prior to the Effective Time will cease to have any
rights with respect to such shares except as provided in the Merger Agreement or
applicable law.
 
    THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE
TO THE SHAREHOLDERS OF VAUGHN.
 
    SHAREHOLDERS ARE URGED TO READ AND CAREFULLY CONSIDER THE INFORMATION
PRESENTED IN THIS PROXY STATEMENT AND TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY TO VAUGHN IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE.
 
                                SPECIAL FACTORS
 
BACKGROUND OF THE MERGER
 
    Over the period of July 31, 1997 through February 5, 1998, the Chief
Executive Officer of the Company received three preliminary contacts regarding
the possible acquisition of the Company, one of which involved taking the
Company private. None of the ensuing discussions advanced beyond the initial
stage. As a result of these contacts, however, the Board of Directors met on
February 19, 1998, to (i) become informed of the nature of the discussions to
date; (ii) be advised by Gray, Plant, Mooty, Mooty & Bennett, P.A. ("Gray
Plant"), legal counsel to the Company, concerning the Board of Directors' legal
duties and obligations; and (iii) establish the Special Committee to evaluate
any acquisition proposal that may be presented to the Company. The Board of
Directors then considered the merits of investigating the market for the Company
given the current market conditions for mergers and acquisitions. Also at this
meeting, four investment bankers made presentations to the Board of Directors
about the services they could provide in exploring a potential sale of the
Company. After the presentations were concluded, the Board of Directors
determined to investigate the market for the Company through engagement of the
services of an investment banker and established the Special Committee. The
Board of Directors gave the Special Committee the power and authority to (i)
make a recommendation to the Board of Directors to
 
                                       14
<PAGE>
accept or reject any proposed sale of the Company or similar transaction; (ii)
engage a financial advisor to review and evaluate, from a financial point of
view, the fairness to the shareholders of any proposed transaction under review
by the Special Committee; (iii) engage a financial advisor to determine the
Company's market value and assist in marketing the Company if determined to be
advisable; (iv) establish subcommittees (composed of one or more members of the
Special Committee) to assist the Special Committee in the fulfillment of its
duties and responsibilities; and (v) review and evaluate the fairness to
Vaughn's shareholders of any proposed transaction which would result in the
Company no longer being publicly traded or any other proposed transaction
involving the sale of the Company or its business whether or not such
transaction would result in the Company no longer being publicly traded. The
members of the Special Committee are Rodney Burwell, Roger Heegaard, Jeffrey
Johnson, Michael Sill, William Smith and Harold Wahlquist, none of whom are
employees of the Company. See "Directors and Executive Officers."
 
    On February 19, 1998, immediately following the adjournment of the Board of
Directors meeting, the Special Committee held its first meeting. The members of
the Special Committee elected Mr. Burwell as Chair of the Special Committee. The
Special Committee then discussed the presentations given by the four investment
bankers at the preceding Board of Directors meeting and unanimously determined
to invite EVEREN Securities, Inc. ("EVEREN") to meet with the Special Committee
on February 26, 1998 to review in further detail its preliminary market
valuation for the Company and its proposal for marketing the Company.
 
    On February 26, 1998, the Special Committee met with representatives of
EVEREN to review EVEREN's assessment of the range of potential values which
might be received by Vaughn's shareholders through a sale of the Company's
business, a proposed timetable for marketing the Company, confidentiality
procedures and obligations, use of financial projections, responsibilities of
the Company and related matters. In addition, the Company reviewed the proposed
fee arrangement with EVEREN for its services. After the EVEREN representatives
left the meeting, the Special Committee unanimously approved the engagement of
EVEREN, on behalf of the Company, to market the Company in accordance with the
terms of EVEREN's proposal presented to the Special Committee.
 
    On March 13, 1998, the Board of Directors held a Special Meeting at which,
among other things, representatives of EVEREN informed the Board of Directors of
a proposed sequence of events which they anticipated would take place over the
next several months in connection with marketing the Company. The initial step
in the process was the preparation and distribution of a Confidential Memorandum
describing the Company which would be distributed to potential interested
parties identified by EVEREN and the Special Committee. Only parties which
entered into a confidentiality agreement would be given the Confidential
Memorandum. Contacted parties would then be invited to submit indications of
interest to acquire the Company by a specified deadline. The Special Committee
would then review the terms of the bids, and select which parties would advance
to the next level of management interviews and in-depth due diligence
activities. Next, the Special Committee would consider the bids, as revised, to
determine whether or not to accept one and proceed to negotiate the terms and
conditions of a definitive agreement for an acquisition transaction. EVEREN
advised the Company that the Company's Products Division would not be of
interest to any of the prospective parties and would have to be sold, liquidated
or otherwise disposed of prior to consummation of any acquisition of the
Company. Information contained in the Confidential Memorandum excluded
information on the Company's Products Division. See "Business and Operations of
Vaughn--Discontinued Operations--Vaughn Products Division."
 
    EVEREN began marketing the Company to a group of qualified financial and
strategic acquirers during the final week of March, 1998. On April 20, 1998, all
parties that had (i) executed a confidentiality agreement, (ii) received a
Confidential Memorandum and (iii) indicated an on-going interest in acquiring
the Company, received a letter from EVEREN requesting the submission of a
preliminary non-binding indication of interest.
 
                                       15
<PAGE>
    On May 5, 1998, the Board of Directors held its regular quarterly meeting,
at which, among other things, the Board reviewed the efforts of EVEREN to market
the Company. The Board considered a status report of EVEREN dated May 4, 1998,
which indicated that May 4, 1998 was the deadline for parties to submit
indications of interest. At that point, EVEREN had received five indications of
interest and requests from at least five other bidders to extend the deadline
for submission of their preliminary bids. The Board also discussed the terms of
the preliminary proposals received to date. Mr. Willette indicated that the next
step was for the Special Committee to meet to select the parties that would move
on to the next level of the process which would involve management interviews
and in-depth due diligence activities.
 
    On May 13, 1998, the Special Committee met with representatives of EVEREN to
review the indications of interest received to date. EVEREN reported on the
bidding process, indicating that as of May 11, 1998, eight indications of
interest had been received. All but one of the indications were cash offers.
EVEREN recommended that the Company not proceed further with two of these
parties. One party's proposal was deemed inadequate and one stock offer from a
private company was unacceptable in structure. After reviewing the bids, the
Special Committee authorized EVEREN to proceed with management interviews and
in-depth due diligence with several of the parties who provided the most
attractive indications of interest and with such other parties that submitted
indications of interest that were at least as attractive as those. From May 20,
1998 through the third week of June, 1998, management of the Company met with
representatives of these parties as well as representatives from a stockholder
of Allied (the "Allied Stockholder") and two other interested parties that
submitted indications after the May 13, 1998 meeting of the Special Committee.
Further due diligence visits with management and lenders for all of these
parties continued through mid-July, 1998.
 
    On July 23, 1998, EVEREN sent to all parties remaining interested in the
Company (including the Allied Stockholder) a letter requesting their submission
of a firm offer, preliminary evidence of ability to finance a transaction and
comments on a proposed form of purchase agreement. EVEREN received final offers
with comments on the proposed form of purchase agreement and preliminary
evidence of ability to finance a transaction from the Allied Stockholder and one
other party (the "Second Bidder") on August 14, 1998. The Allied Stockholder
offered to acquire the Company for cash through a merger transaction. The Second
Bidder offered to acquire the Company for cash through a tender offer. The
Allied Stockholder and the Second Bidder conducted additional due diligence and
site visits between August 14, 1998 and September 6, 1998. During that period,
Vaughn and its advisors began preliminary work to revise and negotiate the
proposed form of purchase agreement with both the Allied Stockholder and the
Second Bidder. On September 8, 1998, the Allied Stockholder and the Second
Bidder submitted final revisions to the economic terms of their offers.
 
    The Special Committee met on September 10, 1998 by telephone conference to
review EVEREN's analysis of the final bids of the Allied Stockholder and the
Second Bidder. Copies of EVEREN's final bid analysis were provided to the
members of the Special Committee prior to this meeting. Representatives of Gray
Plant also participated in this meeting to assist the Special Committee in
reviewing the final bids. After an extensive review and discussion of the
economic terms and structure of each bid, the due diligence activities still
pending for the Allied Stockholder and the Second Bidder, the financing
capabilities of the Allied Stockholder and the Second Bidder, the proposed
premium to be paid by the Allied Stockholder and the Second Bidder, as compared
to the historical trading price of Vaughn Common Stock, as well as to comparable
transactions either completed or pending during the last six months, and the
likelihood of consummating a transaction with the Allied Stockholder and the
Second Bidder, the members of the Special Committee present authorized the
Company to proceed to negotiate a definitive merger agreement with the Allied
Stockholder subject to final approval of the terms of such merger agreement by
the Special Committee and the Board of Directors.
 
    From approximately September 11, 1998 through November 30, 1998, the Allied
Stockholder, its lenders and its other representatives completed their due
diligence review of the Company. Vaughn and
 
                                       16
<PAGE>
the Allied Stockholder, directly and through their respective legal counsel,
also continued negotiations of the business, financial and legal terms of the
Merger Agreement. The parties and their respective legal counsel had exchanged
several drafts of an agreement during this period. Also during this period, the
Company was attempting to sell its Products Division and focusing its efforts on
completing this sale. The Company sold the Products Division as of November 16,
1998.
 
    On December 1, 1998, Allied submitted a final bid to the Special Committee
for its consideration. Among other things, the revised bid adjusted the Merger
Consideration from $11.50 to $10.00 per share of Vaughn Common Stock. The Allied
representative advised the Company that the reduction in Merger Consideration
was necessitated by a combination of factors, the most important of which
related to a significant disruption in the capital markets as well as an
increased concern over the economic prospects for the industry, especially in
light of international market conditions. The revised bid also required that E.
David Willette and M. Charles Reinhart, respectively the Chief Executive Officer
and Chief Financial Officer of the Company, enter into amended employment
agreements and that Douglas Olzenak, a Vice President of Vaughn in charge of
sales, enter into a new written employment agreement. See "Special
Factors--Conflicts of Interest."
 
    At a meeting of the Special Committee on December 4, 1998, the members of
the Special Committee reviewed the terms of the revised bid and the revised
Merger Agreement, as then currently negotiated between the Company and Allied,
and a representative of EVEREN made a presentation to the Special Committee
concerning its fairness opinion. EVEREN provided an oral opinion that the cash
consideration to be paid in the Merger was fair, from a financial point of view,
to Vaughn's shareholders. EVEREN stated that it was prepared to provide a
written opinion to that effect. EVEREN also stated that it had recontacted the
Second Bidder and that the $10.00 share price offered by Allied represented a
premium to the current price offered by the Second Bidder and was the highest
price among all bidders. Based upon that presentation and following a discussion
of the Merger Agreement as currently negotiated by representatives of the
Company and its legal counsel, the Special Committee authorized the Company to
complete negotiations on the Merger Agreement.
 
    Final negotiations of the terms of the Merger Agreement continued from
December 4, 1998 through December 10, 1998. On December 11, 1998, the Special
Committee met, and following review of the Merger Agreement, the Special
Committee unanimously recommended that the directors approve the Merger
Agreement, subject to receipt of the fairness opinion from EVEREN.
 
    On December 11, 1998, immediately following adjournment of the Special
Committee meeting, the Board of Directors met to review the terms of the Merger
Agreement and the recommendation of the Special Committee to approve the Merger
Agreement. At that Board meeting, EVEREN delivered to the Board of Directors its
written opinion that the Merger Consideration was fair, from a financial point
of view, to Vaughn's shareholders. See "Special Factors--Opinion of the
Company's Financial Advisor." Messrs. Willette, Drapeau, Reinhart and Olzenak
participated in the Board discussions and answered questions from the Board of
Directors regarding their proposed continued employment with Allied after
consummation of the Merger. See "Special Factors--Conflicts of Interest." At the
Board meeting on December 11, 1998, all members of the Board of Directors
unanimously approved the Merger Agreement and authorized the Chief Executive
Officer of the Company to execute and deliver the Merger Agreement on behalf of
the Company. After the close of business on December 11, 1998, the Merger
Agreement was executed and delivered, and the Company announced the signing of
the agreement on that date. See "Special Factors--Reasons for the Merger and
Recommendation of the Board of Directors."
 
REASONS FOR THE MERGER AND RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    In reaching its decision to enter into the Merger Agreement, the Board of
Directors of the Company considered a number of factors, including the
following:
 
        (i) The financial presentation of EVEREN (including the assumptions and
    methodologies underlying its analyses and presentations of the stand-alone
    value of the Company) made to the Board
 
                                       17
<PAGE>
    of Directors and the opinion of EVEREN to the effect that, as of December
    11, 1998, the Merger Consideration to be received by the Vaughn shareholders
    in the Merger is fair to such holders from a financial point of view as
    described under "Special Factors--Opinion of the Company's Financial
    Advisor;"
 
        (ii) The premium which the cash consideration to be paid in the Merger
    represents over the historical and then current market prices for shares of
    Vaughn Common Stock, as described under "Special Factors--Opinion of the
    Company's Financial Advisor" and "Information Concerning Vaughn Common
    Stock;"
 
        (iii) Management's discussion with the Board of Directors concerning the
    current conditions of the multimedia business services industry, and the
    advantages which larger companies have over smaller companies such as the
    Company because of a larger sales force and broader product lines;
 
        (iv) A review of strategic alternatives, including possible business
    combinations, and based on the foregoing, the belief that a transaction with
    another company could not reasonably be expected to offer terms and
    advantages comparable to those of a business combination involving Allied;
 
        (v) A review of the terms and conditions of the Merger Agreement,
    including the fact that the Merger Agreement permits the Company's Board of
    Directors, in the exercise of its fiduciary duties, under certain
    conditions, to furnish information to, or engage in negotiations with, third
    parties in response to unsolicited acquisition proposals, and to terminate
    the Merger Agreement, if the Company's Board of Directors determines that a
    superior acquisition proposal has been made, subject to payment of a
    break-up fee (see "The Merger Agreement--Termination Fees");
 
        (vi) The likelihood that TAC will be able to complete the Merger (see
    "The Merger Agreement--Termination"); and
 
        (vii) A review of the Company's business, management, financial
    performance and condition, strategic objectives, prospects and competitive
    position.
 
    The foregoing discussion of the information and factors considered by the
Board of Directors is not intended to be exhaustive. In view of the wide variety
of factors considered in connection with its evaluation of the proposed Merger,
the Board of Directors of the Company did not find it practical to, and did not,
quantify or otherwise attempt to assign relative weights to the specific factors
considered in reaching its determination, although its individual members may
have given differing weights to differing factors.
 
    In making its fairness determination, the Board of Directors considered
that, although the Merger Agreement provides that the Company may not solicit or
encourage any Transaction Proposal (as defined herein), the Company may, if the
Board's fiduciary responsibilities under applicable law (as advised by counsel)
so require, participate in negotiations with third parties with respect to a
Superior Acquisition Proposal before the Merger is consummated. In this regard,
the Board of Directors considered the potential effect on offers or proposals
for a Transaction Proposal that could be caused by the provisions of the Merger
Agreement that provide for the payment of a $1.9 million termination fee and
reimbursement of expenses incurred by TAC up to $900,000 under certain
circumstances. The Board of Directors believed that (i) an effective
solicitation process had taken place in a way that did not adversely affect
relationships with Vaughn's employees, customers and suppliers and that Vaughn's
perceived value to potential acquirers was not diminished; (ii) preliminary
proposals received from and the financing resources of Allied and the Allied
Stockholder enhanced the probability of closing the transaction; and (iii)
Allied and the Allied Stockholder made it clear that it would withdraw its offer
if the termination fees and expense reimbursement terms of the Merger Agreement
would not be accepted. After considering these factors, in addition to the fact
that the termination fees requested by Allied and the Allied Stockholder as a
percentage of Vaughn's total enterprise value was in the range of termination
fees payable in other transactions of similar size since 1995, the Board
concluded that the provisions relating to the expense
 
                                       18
<PAGE>
reimbursement and termination fees requested by Allied and the Allied
Stockholder were not unreasonable and that the Company will still be able to
entertain a Superior Acquisition Proposal that would benefit the shareholders
despite such termination fees and expense.
 
    The Board of Directors of Vaughn believed it was not necessary to structure
the Merger to require approval of at least a majority of unaffiliated
shareholders, nor to have a majority of non-employee directors retain an
unaffiliated representative to act solely on behalf of unaffiliated shareholders
for the purpose of negotiating the terms of the Merger and/or preparing a report
concerning the fairness of the Merger because (i) the Board created a Special
Committee of directors, consisting of directors who are not employees of Vaughn
and who will not have any continuing interest in or other relationship with the
Surviving Corporation, to make a recommendation to engage a financial advisor to
render an opinion as to the fairness, from a financial point of view, of the
consideration to be paid to Vaughn's shareholders in the Merger, (ii) EVEREN,
who was engaged by the Special Committee, delivered its opinion that such
consideration was fair to Vaughn's shareholders, (iii) six of eight directors on
the Board would not have any continuing ownership interest in or other
relationship with the Surviving Corporation and (iv) the Merger was approved
unanimously by all directors of Vaughn.
 
    The Merger is proposed at this time because the Company believes that it
cannot access the necessary capital to execute its growth strategy on a
stand-alone basis given the current conditions in the public equity market. The
Company's business strategy to grow its business-to-business video duplication
sales through acquisitions and new facility openings, and to expand its product
offerings to existing customers by introducing newer multi-media technologies,
such as CD replication, requires substantial capital. Lack of appreciation of
the per share price of Vaughn Common Stock has limited the Company's ability to
raise capital through the public markets. The Company believes that several
factors, including (i) the lack of research coverage by an investment banking
firm, (ii) the small public float and relative illiquidity for Vaughn Common
Stock, (iii) the potential stock overhang from Mr. Willette's ownership position
in Vaughn Common Stock (see "Ownership of Vaughn Common Stock"), (iv) the lack
of other directly comparable public companies and (v) the perception of the
Company's vulnerability to changing multi-media delivery formats, have made it
improbable that the public markets will value Vaughn Common Stock consistent
with the Company's prospects. The Merger is structured so that Vaughn will be
the Surviving Corporation.
 
    In approving the Merger, the Board of Directors was aware that, and
considered as a negative factor that, as a result of the Merger, Vaughn's
shareholders would no longer participate in the future growth and earnings of
the Company. However, after taking into account that the public markets
historically failed to value Vaughn Common Stock consistently with Vaughn's
prospects, the Board of Directors believed that a sale of the Company would
achieve a fair price for the Company and a greater value for Vaughn's
shareholders than if it remained a public company.
 
THE BOARD'S RECOMMENDATION
 
    The Board of Directors of the Company, following the unanimous
recommendation to it by the members of the Special Committee, has unanimously
approved the Merger Agreement, the Merger and the transactions contemplated by
the Merger Agreement and recommends that the shareholders vote "FOR" approval
and adoption of the Merger Agreement and the Merger. The Board believes that the
consideration to be received by unaffiliated Vaughn shareholders is fair and in
the best interests of Vaughn shareholders. Certain members of Vaughn's Board of
Directors have interests in the Merger that may be in conflict with the
interests of Vaughn's shareholders generally. See "Special Factors--Conflicts of
Interest."
 
OPINION OF THE COMPANY'S FINANCIAL ADVISOR
 
    EVEREN has acted as financial advisor to the Company in connection with the
Merger and has assisted the Company's Board of Directors and the Special
Committee in their examination of the fairness, from a financial point of view,
of the cash consideration to be received by the shareholders in the Merger.
 
                                       19
<PAGE>
The Merger Consideration resulted from the negotiations between the Company,
Allied and the Allied Stockholder and was not initially determined by EVEREN.
 
    EVEREN was retained by the Special Committee to: (i) act as financial
advisor in the sale of the Company, and (ii) render a fairness opinion (the
"Opinion") to the Board of Directors with respect to the Merger. EVEREN was
hired based on its qualifications and expertise in providing advice to companies
in merger and acquisition transactions, as well as its reputation as a
nationally recognized investment banking firm. Pursuant to a letter agreement
dated December 3, 1998, the fee payable to EVEREN for its role in rendering its
Opinion to the Special Committee is $100,000. EVEREN will receive a completion
fee for its role as financial advisor upon the closing of the Merger in the
amount of 1.25% of the Enterprise Value (as defined herein) less retainer
payments of $75,000 and the fee paid for rendering the Opinion for $100,000.
 
    At the request of Vaughn, on December 11, 1998, EVEREN delivered an oral
opinion to the Special Committee, which was subsequently confirmed in writing to
the Board of Directors on such date, that, based upon and subject to the matters
set forth in its written opinion as of such date, the cash price of $10.00 per
share of Vaughn Common Stock (the "Merger Consideration") to be paid in the
Merger to the holders of the Vaughn Common Stock was fair, from a financial
point of view. The full text of the written opinion of EVEREN, dated as of
December 11, 1998, is set forth as Annex B to this Proxy Statement and describes
the assumptions made, matters considered and limits on the review undertaken.
Vaughn shareholders are urged to read the opinion in its entirety.
 
    EVEREN's opinion addresses only the fairness of the consideration to be
received in the Merger, from a financial point of view, to the shareholders of
Vaughn and does not constitute a recommendation to any shareholder of Vaughn how
such shareholder should vote with respect to the approval of the Merger.
 
    In addition to the analytical methodologies employed, the Merger
Consideration offered by Allied is the result of a comprehensive marketing
process which included all likely strategic and financial acquirers for the
Company. Upon review of bids received, the Merger Consideration represented the
highest price among all bidders.
 
    In arriving at its opinion, EVEREN assumed and relied upon the accuracy and
completeness of the financial and other information obtained from public sources
or provided to it by the Company, and EVEREN has not assumed responsibility for
any independent verification of such information or undertaken any obligation to
verify such information. In addition, with respect to the financial forecasts
and projections of the Company used in EVEREN's analysis, the management of the
Company informed EVEREN that such forecasts and projections represent the best
current judgment of the management of the Company as to the future financial
performance of the Company on a stand-alone basis, and EVEREN assumed that the
projections had been reasonably prepared based on such current judgment. EVEREN
assumed no responsibility for and expresses no view as to such forecasts and
projections or the assumptions on which they were based.
 
    EVEREN also took into account its assessment of general economic, market and
financial conditions and its experience in similar transactions, as well as its
experience in securities valuation in general. EVEREN's opinion necessarily is
based upon regulatory, economic, market and other conditions, as well as
information made available to EVEREN as of December 11, 1998. The regulatory,
economic, market and other conditions and the information made available to
EVEREN could only be evaluated by EVEREN on the date of the fairness opinion.
 
    In connection with rendering its opinion, dated as of December 11, 1998,
EVEREN: (i) reviewed the Merger Agreement in substantially final form, (ii)
reviewed a draft of Vaughn's merger proxy statement, (iii) reviewed Vaughn's
annual report on Forms 10-K for the years ended January 31, 1997, and 1998, (iv)
reviewed Vaughn's quarterly reports on Forms 10-Q for the three months ended
July 30, 1998 and October 31, 1998, (v) reviewed Vaughn's current report on Form
8-K with a Date of Report of November 16, 1998, (vi) reviewed certain non-public
operating and financial information, including financial projections, relating
to Vaughn's business prepared by management of Vaughn, (vii) interviewed certain
 
                                       20
<PAGE>
members of Vaughn's management to discuss its operations, financial statements
and future prospects, (viii) reviewed the historical share prices and trading
volumes of Vaughn's Common Stock, (ix) reviewed premiums paid in recent merger
transactions of comparable size, (x) reviewed publicly available financial data
and stock market performance data of other publicly traded multi-media companies
which were deemed comparable to Vaughn, (xi) reviewed the terms of selected
recent acquisitions of companies which were deemed comparable to Vaughn, (xii)
reviewed termination fees agreed to on recent transactions of comparable size;
and (xiii) conducted such other studies, analyses, inquiries and investigations,
as deemed appropriate.
 
    The following is a summary of the six primary valuation analyses of Vaughn
performed by EVEREN: (i) premiums in recent merger transactions of comparable
size, (ii) the Enterprise Value and Equity Value of the Transaction compared to
comparable publicly traded multi-media companies, (iii) the Enterprise Value of
the Transaction compared to comparable merger transactions, (iv) the Enterprise
Value and Equity Value of the Transaction compared to the value per share
derived from a discounted cash flow analysis, (v) Vaughn's historical share
price performance, and (vi) other relevant factors.
 
    ENTERPRISE VALUE ANALYSIS:
 
    EVEREN calculated the Enterprise Value, defined as the transaction value of
equity, which in the case of the Merger is based on Allied's offer of $10.00 per
share for Vaughn Common Stock multiplied by the primary shares outstanding plus
the cash paid to option holders based on the difference between the Merger
Consideration and the exercise price of their options (the "Equity Value"), plus
debt (including the obligation of all transaction expenses incurred by Vaughn).
Enterprise Value was analyzed as a multiple of latest twelve months through
October 31, 1998 ("LTM") net sales, earnings before interest, taxes,
depreciation and amortization ("EBITDA") and earnings before interest and taxes
("EBIT"). Equity Value was analyzed as a multiple of 1998 and 1999 estimated net
income. The Enterprise Value multiples of LTM net sales, EBITDA and EBIT
associated with the Merger are 0.7x, 5.7x and 9.5x, respectively. The Equity
Value multiples of 1998 and 1999 estimated net income associated with the Merger
are 15.5x and 9.7x, respectively. EVEREN calculated net sales, EBITDA and EBIT
multiples based on Enterprise Value, and net income multiples based on Equity
Value in order to compare such multiples to the multiples calculated in the
comparable company trading analysis and comparable transaction analysis
discussed below.
 
    PREMIUM ANALYSIS:
 
    EVEREN reviewed premiums paid on target companies' stock prices one day, one
week and one month prior to the announcement of an acquisition. EVEREN reviewed
transactions that met the following criteria: (i) Enterprise Value was greater
than $50 million and less than $150 million, (ii) acquirer acquired a 50% or
greater interest in the target, (iii) the announcement occurred between May 30,
1998 and November 30, 1998, and (iv) the target companies excluded those
involved in financial services, real estate, telecommunications, and healthcare
companies. The review resulted in a range of premiums (discounts) paid: (i) one
day prior to announcement of (21.4%) to 100.0%, with a median of 14.9% and a
mean of 22.9%, (ii) one week prior to announcement of (22.3%) to 156.0%, with a
median of 22.1% and a mean of 29.9%, and (iii) one month prior to announcement
of (7.5%) to 166.7%, with a median of 28.6% and a mean of 33.6%. Utilizing a
subset of transactions including 15 of the 27 transactions previously analyzed
with Enterprise Values between $50 million and $100 million, the median one day,
one week and one month premiums were 13.6%, 22.1% and 26.1%, respectively.
 
    EVEREN noted that the offer price for Vaughn of $10.00 per share was a
21.2%, 35.6% and 27.0% premium to the closing price of Vaughn's common stock one
day, one week and one month, respectively, prior to the first public
announcement of the Merger and that the premium offered to shareholders based on
closing prices one day, one week and four weeks prior to the announcement
compares favorably with premiums paid in the other transactions reviewed by
EVEREN, especially those with Enterprise Values between $50 million to $100
million.

    EVEREN prepared a comparable transaction analysis that consisted of
reviewing financial aspects of selected acquisitions of assets, businesses or
interests in businesses in the media duplication and multi-media related
services businesses, which EVEREN determined to be in similar lines of business
as Vaughn ("Selected Comparable Transactions"). EVEREN noted that no such
transactions took place under directly comparable market conditions or
competitive conditions or circumstances and that, accordingly, qualitative
judgments must be made concerning the differences between the characteristics of
these transactions and other factors and issues which would affect the price an
acquirer is willing to pay in an acquisition. Selected Comparable Transactions
included (acquirer/target): VDI Media/Dubs, Inc.; Citicorp Venture
Capital/Allied Digital Technologies Corp.; Technicolor Video Services/Nimbus CD
International, Inc.; Four Media/Video Symphony, Inc.; Cinram International,
Inc./Sony Music--Duplication Assets; The Todd AO Corp./Hollywood Digital, Cinram
International, Inc./Polygram NV--Disc Manufacturing; Cinram International,
Inc./Quixote--Disc Manufacturing; Four Media/Anderson Film Industries, Corp.;
Cinram International, Inc./Videoprint, Inc.; Cinram International,
Inc./Duplication France. EVEREN also investigated information available on the
pending acquisition of KAO Corporation's U.S. operations by Zomax Corporation.
The analysis of Selected Comparable Transactions yielded a range of transaction
value multiples of LTM net sales of 0.1x to 2.0x, with a median of 0.7x and mean
of 0.9x, LTM EBITDA of 2.6x to 8.7x, with a median of 4.6x and a mean of 5.6x,
LTM EBIT multiples of 4.4x to 14.6x, with a median of 10.4x and a mean of 9.9x.
EVEREN noted that the Enterprise Value multiples of LTM sales, EBITDA and EBIT
compared favorably with the respective multiples derived in the comparable
transaction analysis. In particular, the Enterprise Value multiples compared
favorably to Citicorp Venture Capital's acquisition of Allied where the
Enterprise Value to LTM sales, LTM EBITDA, and LTM EBIT were 0.7x, 4.6x and
8.3x, respectively.

</TABLE>
 
    EVEREN prepared a comparable company trading analysis that consisted of
comparing financial market and operating performances of selected publicly
traded media duplication and other multi-media services companies, which EVEREN
determined to be in somewhat similar lines of business as Vaughn ("Selected
Comparable Companies"). EVEREN noted that each of the selected companies is
distinguishable from Vaughn, and that, accordingly, an analysis of the results
of the foregoing necessarily involves complex considerations and judgments
concerning differences in the financial and operating characteristics of the
companies and other factors to which they are being compared. The multiples and
ratios for each of the Selected Comparable Companies were based on the most
recent publicly available information and published estimates of research
analysts. The Selected Comparable Companies included: Four Media
 
                                       22
<PAGE>
Company; Video Services Corporation; The Todd-AO Corporation; Cinram
International, Inc. and VDI Media, Inc. With respect to the Selected Comparable
Companies, EVEREN considered total enterprise value as a multiple of LTM net
sales, LTM EBITDA and LTM EBIT. EVEREN's analysis of the Selected Comparable
Companies indicated enterprise value multiples of LTM net sales ranging from
0.9x to 1.9x, with a median of 1.6x and a mean of 1.5x; enterprise value
multiples of LTM EBITDA ranging from 4.9x to 9.0x, with a median of 6.0x and a
mean of 6.5x; and enterprise value multiples of LTM EBIT ranging from 9.4x to
18.6x, with a median of 12.6x and a mean of 13.6x. In addition, with respect to
the Selected Comparable Companies, EVEREN considered equity value as a multiple
of forward 1998 and 1999 net income. EVEREN's analysis of the Selected
Comparable Companies indicated equity value multiples of 1998 (estimated) net
income ranging from 12.1x to 14.4x, with a median of 13.5x and a mean of 13.4x.
EVEREN's analysis of the Selected Comparable Companies indicated an equity value
multiple of 1999 (estimated) net income of 7.7x (only one such estimate exists).
EVEREN noted that the Merger Consideration multiples are below that of the
Selected Comparable Companies. However, compared to the publicly traded
comparable group, Vaughn has lower margins and growth rates than the median for
the peer group. With a three year compound annual growth rate from 1995 to 1997
of sales of 18.6%, Vaughn ranks below the median growth rate of 37.9%. Likewise,
Vaughn's LTM EBITDA margin of 13.4% falls below the median of the Selected
Comparable Companies at 21.6%. With the exception of Video Services, Vaughn is
the smallest company in terms of sales and market capitalization and is at
competitive disadvantage in the marketplace in terms of raising public capital
or attracting institutional interest. As such, the use of this analysis is not
as relevant as other methodologies.
 
    DISCOUNTED CASH FLOW ANALYSIS:
 
    The Discounted Cash Flow Analysis ("DCF") attempts to value Vaughn's shares
today using the sum of (i) the discounted cash flows of the Company over the
course of the next five years, plus (ii) a discounted terminal value. Although
this methodology is utilized often in investment cost-benefit analysis, it is
heavily dependent on the accuracy of projections, the discount rate and the
terminal value multiples. In analyzing the Merger Consideration on a DCF basis,
we utilized management's profit projections under a "No Acquisitions" case,
capital expenditure projections provided to bidders during the sale process, a
terminal multiple range of 4.5x to 5.5x EBITDA (the approximate mean and median
range for Comparable Transactions), and a discount rate of 15% to 20%, which
represents a reasonable discount rate given the capital and size of the Company.
Based on such analysis, EVEREN derived a range of Enterprise Values and
subtracted the sum of the current debt outstanding plus the difference between
the Merger Consideration and the exercise price for all in-the-money options to
arrive at an implied Equity Value. Dividing by the number of Vaughn shares
currently outstanding as of October 31, 1998, yielded implied equity values per
share of Vaughn of $6.64 to $11.55. The Merger Consideration compared favorably
with this range of implied equity values per share calculated in the DCF
Analysis.
 
    OTHER ANALYSES AND FACTORS:
 
    In rendering its opinion, EVEREN: (i) prepared a history of trading prices
for Vaughn Common Stock from December 11, 1988 through December 11, 1998, which
showed a range of prices of $0.44 to $19.00 with an average price of $4.36 per
share over this period; (ii) prepared a history of trading prices for Vaughn
Common Stock from December 11, 1997 through December 11, 1998, which showed a
range of prices of $5.25 to $10.38 with an average price of $7.35 per share over
this period; (iii) prepared a history of trading volumes for Vaughn Common Stock
from December 11, 1997 through December 11, 1998, which showed that greater than
98% of the shares traded at or below the Merger Consideration of $10.00 over the
last year, and (iv) reviewed financial and operating characteristics of Vaughn
and its industry performance.
 
    The foregoing is a summary of the material aspects of the financial analyses
used by EVEREN in connection with rendering its opinion. The preparation of a
fairness opinion is a complex process and is
 
                                       23
<PAGE>
not necessarily susceptible to partial analysis or summary description.
Selecting portions of the analyses or of the summary set forth above, without
considering the analyses as a whole, could create an incomplete view of the
processes underlying EVEREN's opinion. In arriving at its opinion, EVEREN
considered the results of all such analyses. The analyses were prepared solely
for the purposes of EVEREN providing its opinion as to the fairness of the
Merger Consideration, from a financial point of view, to the holders of Vaughn
Common Stock, and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually may be sold. Any analysis of
the fairness of the Merger Consideration to be offered in the Merger, from a
financial point of view, to the holders of Vaughn Common Stock, involves complex
considerations and judgments concerning differences in the potential financial
and operating characteristics of the comparable companies and transactions and
other factors in relation to the trading and acquisition values of the
comparable companies. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than those suggested by such analyses. The estimates utilized
by EVEREN were developed solely for purposes of its analysis and the
presentations to the Vaughn Board of Directors and reflected computations of the
potential values through the application of various generally accepted valuation
techniques. Such estimates may not reflect actual market values, and do not
necessarily reflect values which may be realized if any other assets of Vaughn
are sold. EVEREN has not appraised or undertaken any valuation of any assets or
property nor has it made any solvency analysis of Vaughn. EVEREN's opinion and
the related presentation to the Vaughn Board on December 11, 1998 was one of
many factors taken into consideration by the Vaughn Board in making its
determination to approve the Merger. The foregoing summary does not purport to
be a complete description of the analyses performed by EVEREN.
 
    EVEREN's opinion is for the use and benefit of the Vaughn Board of Directors
in its consideration of the Merger. This opinion is not intended to be and does
not constitute a recommendation to any shareholder as to how such shareholder
should vote with respect to the Merger. EVEREN was not requested to opine as to,
and its opinion does not in any manner address, Vaughn's underlying business
decision to proceed with or effect the Merger, or the relative merits of the
Merger as compared to any alternative business strategies which might exist for
Vaughn or the effect of any other transaction in which Vaughn might engage.
 
    Pursuant to a letter agreement dated December 3, 1998, Vaughn paid to EVEREN
in December 1998, a cash fee of $100,000 after EVEREN delivered its opinion to
the Vaughn Board of Directors on December 11, 1998. Furthermore, Vaughn has
agreed to reimburse EVEREN for certain out-of-pocket expenses and to indemnify
EVEREN for certain liabilities arising in connection with EVEREN's opinion.
 
    As compensation for its services as financial advisor to the Company, the
Company has paid EVEREN a retainer of $75,000 to be credited against a fee,
payable upon the consummation of the Merger, in an amount equal to 1 1/4% of the
aggregate consideration received by the shareholders in connection with the
Merger, based on a share value of up to $15 per share, and 3% of the aggregate
consideration received by the Shareholders in excess of $15 per share. The
Company has also agreed to reimburse EVEREN for its reasonable out-of-pocket
expenses in connection with the performance of its services not to exceed
$25,000 in the aggregate without the Company's prior approval. In the ordinary
course of its business, EVEREN may trade Vaughn Common Stock for the accounts of
its customers. EVEREN does not hold, for its own account, any shares of Vaughn
Common Stock.
 
CERTAIN EFFECTS OF THE MERGER
 
    Current Vaughn shareholders will not have an opportunity to continue their
equity interest in the Surviving Corporation and therefore will not share in the
future earnings and potential growth of Vaughn, nor have the right of equity
ownership. Upon completion of the Merger, Vaughn Common Stock will no longer be
quoted on Nasdaq, trading information will no longer be available and the
registration of Vaughn Common Stock under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), will be terminated. The termination of the
registration of Vaughn Common Stock under the Exchange Act will
 
                                       24
<PAGE>
reduce the information required to be furnished to the SEC and will make certain
provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b) and the requirement of furnishing a proxy or
information statement in connection with shareholder meetings, no longer
applicable.
 
    The receipt of cash pursuant to the Merger will be a taxable transaction.
See "Special Factors-- Certain Federal Income Tax Consequences."
 
CONFLICTS OF INTEREST
 
    In considering the recommendation of Vaughn's Board of Directors with
respect to the Merger, the Merger Agreement and the transactions contemplated by
the Merger Agreement, Vaughn's shareholders should be aware that certain members
of Vaughn's management and Board of Directors (identified in the following
paragraphs) have interests in the Merger that may be generally considered in
conflict with the interests of Vaughn shareholders generally. The Board of
Directors of Vaughn was aware of these interests and considered them, among
other matters, in approving the Merger, the Merger Agreement and the
transactions contemplated by the Merger Agreement. These interests are discussed
below.
 
    WILLETTE OPTION TERMINATION AND GRANT AGREEMENT; WILLETTE SUBSCRIPTION
     AGREEMENT
 
    In connection with the Merger, Willette and Allied entered into the Willette
Option Termination and Grant Agreement, which is attached hereto as Annex D and
is incorporated herein by reference. Pursuant to the Willette Option Termination
and Grant Agreement, immediately prior to the Effective Time, Willette, Chief
Executive Officer and Director of Vaughn, will cancel certain stock options held
by him to purchase 128,500 shares of Vaughn Common Stock, representing (i) stock
options to purchase 20,500 shares of Vaughn Common Stock at an exercise price of
$3.1250 per share, (ii) stock options to purchase 22,000 shares of Vaughn Common
Stock at an exercise price of $5.10 per share, (iii) stock options to purchase
34,000 shares of Vaughn Common Stock at an exercise price of $5.8438 per share,
(iv) stock options to purchase 27,000 shares of Vaughn Common Stock at an
exercise price of $7.5438 per share, and (v) stock options to purchase 25,000
shares of Vaughn Common Stock at an exercise price of $11.05 per share (the
"Willette Options"). In consideration for such cancellation, Willette will
acquire a non-qualified option (the "Allied Option") consisting of the right to
purchase 10,000 shares of Series C Preferred Stock of Allied, par value $.01 per
share ("Allied Series C Preferred"), at an exercise price of $543,634.20,
subject to the terms and conditions set forth in a Stock Option Agreement and
Letter of Grant (the "Option Certificate") to be entered into on the Closing
Date by and between Allied and Willette. The Allied Series C Preferred has a
stated value of $100.00 per share; therefore, the Allied Option exercisable for
10,000 shares of Allied Series C Preferred has an ascribed value of $1 million.
Assuming Merger Consideration of $10.00 per share, subject to the terms and
conditions of the Merger Agreement, Willette would be entitled to an aggregate
spread of $456,365.80 in cancellation of the Willette Options. The exercise
price of $543,634.20 was calculated to give Willette equivalent value by
subtracting $456,365.80 from the $1 million ascribed value. The cancellation of
the Willette Options and grant of the Allied Option will take place immediately
prior to the Effective Time on the Closing Date.
 
    Also in connection with the Merger, Willette and Allied entered into the
Willette Subscription Agreement pursuant to which Willette will purchase 22,820
shares of Class A Common Stock of Allied, par value $.01 per share ("Allied
Class A Common"), at a price of $5.00 per share, for $114,100 plus an additional
4,500 shares as his allocation under Allied's management equity program, at a
price of $5.00 per share, for $22,500, for a total purchase of 27,320 shares of
Allied Class A Common for $136,600. Willette will also purchase 4,289 shares of
Series B Preferred Stock of Allied, par value $.01 per share ("Allied Series B
Preferred" and together with the Allied Class A Common, the "Willette Shares"),
at a price of $100.00 per share, for a total purchase price of $428,900. The
closing of the purchase and sale of the Willette Shares will take place
immediately prior to the Effective Time on the Closing Date. The
 
                                       25
<PAGE>
effectiveness of the Willette Subscription Agreement and the Willette Option
Termination and Grant Agreement are subject to the consummation of the
transactions contemplated by the Merger Agreement (the "Transactions").
 
    EMPLOYMENT AGREEMENTS
 
    Prior to the Merger, Vaughn had existing employment agreements with
Willette, M. Charles Reinhart ("Reinhart") and Donald J. Drapeau ("Drapeau"). In
connection with the Merger, employment agreements of Willette and Reinhart have
been amended.
 
    Pursuant to Amendment No. 1 to Mr. Willette's employment agreement, the
material changes are as follows: (a) ADI assumes all of Vaughn's
responsibilities under Mr. Willette's amended employment agreement; (b) Mr.
Willette's position is changed to Executive Vice President of ADI from Chief
Executive Officer of Vaughn; and (c) Mr. Willette's annual base salary is
increased from $200,000 to $225,000 per year.
 
    Pursuant to Amendment No. 1 to Mr. Reinhart's employment agreement, the
material changes are as follows: (a) ADI assumes all of Vaughn's
responsibilities under Mr. Reinhart's amended employment agreement; (b) the
three-year term of Reinhart's employment agreement is shortened to terminate on
April 1, 2000 (from March 13, 2001), with no right of renewal; (c) the
non-competition restriction period binding on Mr. Reinhart is shortened to
eighteen months from five years; and (d) Mr. Reinhart is entitled to severance
compensation equal to $160,000, payable monthly in twelve equal installments
plus other benefits in the event of any of the following: (i) his employment
agreement is terminated without "Cause" (as defined in Mr. Reinhart's employment
agreement), (ii) the parties mutually agree to terminate his employment
agreement, (iii) his employment agreement expires by its own terms, or (iv) Mr.
Reinhart terminates his employment agreement for "Good Reason" (as defined in
Mr. Reinhart's employment agreement).
 
    The effectiveness of the amendments to the employment agreements of Mr.
Willette and Mr. Reinhart are subject to the consummation of the Transactions.
 
    Under existing employment agreements with Drapeau and Reinhart, each of them
will receive $100,000 in one lump sum payment upon the consummation of a "Change
of Control" of Vaughn. An additional $100,000 is payable to Drapeau and Reinhart
on the date one year after the consummation of such Change of Control, subject
to certain conditions in the employment agreements. Completion of the Merger
will constitute a "Change of Control" under the employment agreements and will
entitle Drapeau and Reinhart to these payments.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion is a general summary of the material United States
federal income tax consequences of the Merger. This discussion is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), regulations promulgated
by the United States Treasury Department, judicial authorities, and current
rulings and administrative practice of the Internal Revenue Service (the
"Service") in each case as in effect as of the date hereof and all of which are
subject to change at any time, possibly with retroactive effect. This discussion
does not address all aspects of federal income taxation that might be relevant
to particular holders of Vaughn Common Stock in light of their status or
personal investment circumstances; nor does it discuss the consequences to such
holders who are subject to special treatment under the federal income tax laws
such as foreign persons, dealers in securities, regulated investment companies,
life insurance companies, other financial institutions, tax-exempt
organizations, pass-through entities, taxpayers who hold Vaughn Common Stock as
part of a "straddle," "hedge" or "conversion transaction" or who have a
"functional currency" other than the United States dollar or to persons who
 
                                       26
<PAGE>
have received their Vaughn Common Stock as compensation. Further, this
discussion does not address the state, local or foreign tax consequences of the
Merger.
 
    For United States federal income tax purposes, TAC will be disregarded as a
transitory entity and the Merger of TAC with and into Vaughn will be treated as
exchanges of a portion of Vaughn Common Stock for the cash in the Merger by its
holders.
 
    The receipt of the cash consideration in the Merger by holders of Vaughn
Common Stock will be a taxable transaction for federal income tax purposes. Each
holder's gain or loss per share will be equal to the difference between the cash
consideration received in the Merger and the holder's basis per share in the
Vaughn Common Stock. Except as provided in the following paragraph, if a holder
holds Vaughn Common Stock as a capital asset, the gain or loss from the exchange
will be a capital gain or loss. This gain or loss will be long-term if the
holder's holding period is more than twelve months. Under current law, net
long-term capital gains of individuals are subject to a maximum federal income
tax rate of 20% (not taking into account any phase-out of personal exemptions
and certain itemized deductions) whereas the maximum federal income tax rate on
ordinary income and net short-term capital gains (I.E., gain on capital assets
held for less than twelve months) of an individual is currently 39.6% (not
taking into account any phase-out of personal exemptions and certain itemized
deductions). For corporations, capital gains and ordinary income are taxed at
the same maximum rate of 35%. Capital losses are currently deductible only to
the extent of capital gains plus, in the case of taxpayers other than
corporations, $3,000 of ordinary income ($1,500 in the case of married
individuals filing separate returns). In the case of individuals and other
non-corporate taxpayers, capital losses that are not currently deductible may be
carried forward to other years, subject to certain limitations. In the case of
corporations, capital losses that are not currently deductible may generally be
carried back to each of the three years preceding the loss year and forward to
each of the five years succeeding the loss year, subject to certain limitations.
 
    A holder of Vaughn Common Stock may be subject to backup withholding at the
rate of 31% with respect to payments of cash consideration in the Merger
received pursuant to the Merger, unless the holder (a) provides a correct
taxpayer identification number ("TIN") in the manner required or (b) is a
corporation or other exempt recipient and, when required, demonstrates this
fact. To prevent the possibility of backup federal income tax withholding on
payments made to certain holders with respect to shares of Vaughn Common Stock
pursuant to the Merger, each holder must provide the disbursing agent with his
correct TIN by completing a Form W-9 or Substitute Form W-9. A holder of Vaughn
Common Stock who does not provide Vaughn with his or her correct TIN may be
subject to penalties imposed by the Service, as well as backup withholding. Any
amount withheld under these rules will be creditable against the holder's
federal income tax liability. Vaughn (or its agent) will report to the holders
of Vaughn Common Stock and the Service the amount of any "reportable payments,"
as defined in Section 3406 of the Code, and the amount of tax, if any, withheld
with respect thereto.
 
    THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION ONLY AND IS NOT A
COMPLETE DESCRIPTION OF ALL OF THE POTENTIAL TAX CONSEQUENCES THAT MAY OCCUR AS
A RESULT OF THE MERGER. VAUGHN SHAREHOLDERS SHOULD THEREFORE CONSULT THEIR TAX
ADVISORS REGARDING THE FEDERAL TAX CONSEQUENCES OF THE MERGER, AS WELL AS THE
TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR OTHER
JURISDICTION OF THE ABOVE DESCRIBED TRANSACTIONS.

                                   THE MERGER
 
    THE FOLLOWING IS A SUMMARY OF THE MERGER AGREEMENT, A COPY OF WHICH IS
ATTACHED AS ANNEX A TO THIS PROXY STATEMENT AND IS INCORPORATED HEREIN BY
REFERENCE. SUCH SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MERGER
AGREEMENT. SHAREHOLDERS ARE URGED TO REVIEW THE MERGER AGREEMENT CAREFULLY IN
ITS ENTIRETY.
 
OWNERSHIP OF CAPITAL STOCK
 
    Concurrently with the Merger, it is anticipated that the following steps
will be taken:
 
    (a) TAC has issued one thousand shares of common stock of TAC, par value
$0.01 per share, ("TAC Common Stock") to ADI. Pursuant to the Merger, one
thousand shares of TAC Common Stock (representing each share of TAC Common Stock
outstanding immediately prior to the Effective Time of the Merger) will be
canceled and converted on a one-for-one basis into one share of common stock of
the Surviving Corporation.
 
    (b) Pursuant to the Merger, each share of Vaughn Common Stock outstanding as
of the Record Date (less any shares owned by Vaughn shareholders who are
entitled to, and have perfected, their dissenters' rights) will be canceled and
converted into the right to receive $10.00 per share in cash. For accounting
purposes, the Company will be deemed to have purchased these shares.
 
    (c) As of the Record Date, there were options outstanding to purchase an
aggregate of 447,336 shares of Vaughn Common Stock (the "Vaughn Stock Options").
Other than as expressly set forth in the Willette Option Termination and Grant
Agreement, Vaughn shall adjust the terms of all Vaughn Stock Options to provide
that, at the Effective Time, each Vaughn Stock Option outstanding immediately
prior to the Effective Time, whether or not then vested or exercisable, shall be
canceled and thereafter the former holder thereof shall be entitled by having
held such Vaughn Stock Option only to a payment from the Surviving Corporation
(subject to any applicable withholding taxes, as the case may be) equal to the
product of (i) the total number of shares of Vaughn Common Stock subject to such
Vaughn Stock Option and (ii) the excess of $10.00 over the exercise price per
share of Vaughn Common Stock subject to such Vaughn Stock Option, payable in
cash immediately following the Effective Time. See "Interests of Certain Persons
in the Merger--Willette Option Termination and Grant Agreement;--Treatment of
Options."
 
BENEFITS UNDER EMPLOYMENT AGREEMENTS
 
    Vaughn is a party to employment agreements with two of its executive
officers that will require the payment of a lump sum amount as a result of the
completion of the Merger. See "Special Factors-- Conflicts of Interest."
 
EMPLOYMENT BY VAUGHN
 
    As a result of the Merger, Vaughn will be the Surviving Corporation, and
employees of Vaughn will become employees of the Surviving Corporation.
 
INDEMNIFICATION
 
    Pursuant to the terms of the Merger Agreement, for a period of six years
after the Effective Time, and subject to any limitation imposed from time to
time under applicable law, the Surviving Corporation will indemnify and hold
harmless the present and former officers and directors of Vaughn and its former
subsidiaries in respect of acts or omissions occurring prior to the Effective
Time to the maximum extent provided under Vaughn's Articles of Incorporation and
by-laws, or any of its former subsidiary's certificate of incorporation or
by-laws, in either case, as in effect on the date of the execution of the Merger
Agreement.
 
    For a period of six years after the Effective Time, the Surviving
Corporation will provide officers' and directors' liability insurance in respect
of acts or omissions occurring prior to the Effective Time covering each such
person currently covered by Vaughn's or any of its former subsidiary's officers'
and directors' liability insurance policy on terms with respect to coverage and
amount no less favorable than those of such
 
                                       28
<PAGE>
policy in effect on the date hereof, provided that, in satisfying its obligation
to provide liability insurance, the Surviving Corporation will not be obligated
under the Merger Agreement to pay premiums in excess of 150% of the amount per
annum Vaughn paid in its last full fiscal year.
 
    The Company's Articles of Incorporation contains provisions eliminating a
director's personal liability for monetary damages to the Company and its
shareholders arising from a breach of a director's fiduciary duty except for
liability (i) for any breach of the director's duty of loyalty to the Company or
its shareholders; (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law; or (iii) for any
transaction from which the director derived an improper personal benefit.
 
    In addition, the Company's By-Laws require the Company to indemnify Vaughn
directors and officers to the fullest extent permitted under the law. The
Company maintains director and officer insurance coverage for directors and
officers of Vaughn.
 
CONDUCT OF VAUGHN'S BUSINESS AFTER THE MERGER
 
    As a condition to the consummation of the Merger, all directors of Vaughn
designated by TAC will submit their resignations effective upon consummation of
the Merger; however, it is anticipated that neither Vaughn nor TAC will change
the composition of management immediately following the Effective Time. TAC and
members of management of Vaughn expect that the day-to-day business and
operations of Vaughn will be conducted substantially as they are currently being
conducted by Vaughn. In addition, after the Merger, Vaughn intends to seek
certain strategic acquisitions of companies in comparable industries to take
advantage of increased margins by combining operations.
 
    Other than the transactions contemplated hereby and the proposed financing,
the Company does not have, nor does it anticipate, any plans or proposals which
would result in a sale or transfer of a material amount of assets, or a material
change in the Company's dividend rate or policy or indebtedness or
capitalization. See "The Merger--Financing."
 
EFFECTIVE TIME
 
    The Merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Minnesota or at such later time as
may be specified in the certificate of merger. The date and time of
effectiveness of the Merger is referred to generally in this Proxy Statement as
the "Effective Time." The Effective Time is currently expected to occur as soon
as practicable after the Special Meeting, subject to approval of the principal
terms of the Merger Agreement at the Special Meeting and satisfaction or waiver
of the terms and conditions set forth in the Merger Agreement.
 
REGULATORY REQUIREMENTS
 
    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"), certain acquisition transactions may not be consummated unless
notice has been given and certain information furnished to the Antitrust
Division of the United States Department of Justice (the "Antitrust Division")
and the Federal Trade Commission (the "FTC") and specified waiting period
requirements have been satisfied, unless earlier termination has been granted.
The Company and TAC each filed with the Antitrust Division and the FTC a
Notification and Report Form with respect to the Merger on December 14, 1998. On
December 31, 1998, the FTC notified the Company and TAC that the waiting period
under the HSR Act had been terminated. At any time before or after the Effective
Time, and despite termination of the HSR Act waiting period, the Antitrust
Division or any state could take such action under the antitrust laws as it
deems necessary or desirable in the public interest, including seeking to enjoin
consummation of the Merger, or seeking divestiture of substantial assets of the
Company and TAC. Private parties also may seek to take legal action under the
antitrust laws under certain circumstances.

DISSENTERS' RIGHTS
 
    Sections 302A.471 and 302A.473 of the MBCA entitle any shareholder who
objects to the Merger and who follows the procedures prescribed by Section
302A.473 to receive in lieu of the Merger Consideration cash equal to the "fair
value" of such shareholder's shares of Vaughn Common Stock. Set forth below is a
summary of the procedures relating to the exercise of such dissenters' rights.
This summary does not purport to be a complete statement of dissenters' rights
and is qualified in its entirety by reference to Sections 302A.471 and 302A.473
of the MBCA, which are reproduced in full as Annex C to this Proxy Statement,
and to any amendments to such provisions as may be adopted after the date of
this Proxy Statement.
 
    ANY SHAREHOLDER CONTEMPLATING THE POSSIBILITY OF DISSENTING FROM THE MERGER
SHOULD CAREFULLY REVIEW THE TEXT OF ANNEX C (PARTICULARLY THE SPECIFIED
PROCEDURAL STEPS REQUIRED TO PERFECT DISSENTERS' RIGHTS, WHICH ARE COMPLEX) AND
SHOULD ALSO CONSULT LEGAL COUNSEL. SUCH RIGHTS WILL BE LOST IF THE PROCEDURAL
REQUIREMENTS OF SECTION 302A.473 OF THE MBCA ARE NOT FULLY AND PRECISELY
SATISFIED.
 
    Under the MBCA, any shareholder who (i) files with the Company before the
Special Meeting written notice of his or her intent to demand the fair value for
his or her shares of Vaughn Common Stock if the Merger is consummated and
becomes effective and (ii) does not vote his or her shares of Vaughn Common
Stock at the Special Meeting in favor of the proposal to approve the Merger
shall be entitled, if the Merger is approved and effected, to receive a cash
payment equal to the fair value of such shareholder's shares of Vaughn Common
Stock upon compliance with the applicable statutory procedural requirements.
While a shareholder who votes for the Merger will have no dissenters' rights
under the MBCA, the failure by any shareholder to vote against the proposal to
approve the Merger will not in and of itself constitute a waiver of such rights.
 
    Written notice of a shareholder's intent to demand payment for such
shareholder's shares of Common Stock must be filed with the Company at: 5050
West 78th Street, Minneapolis, Minnesota 55435, Attn: Corporate Secretary,
before the vote on the Merger at the Special Meeting. A vote against the Merger
at the Special Meeting will not constitute the notice required under the MBCA. A
shareholder who does not satisfy each of the requirements of Sections 302A.471
and 302A.473 of the MBCA is not entitled to payment for such shareholder's
shares of Vaughn Common Stock under the dissenters' rights provisions of the
MBCA and will be bound by the terms of the Merger Agreement if the Merger is
consummated.
 
    If the Merger is approved at the Special Meeting, the Company must send
written notice to all shareholders who have given written notice of dissent and
not voted in favor of the Merger a notice containing: (i) the address where the
demand for payment and certificates must be sent and the date by which they must
be received, (ii) any restrictions on transfer of uncertificated shares that
will apply after the demand for payment is received, (iii) a form to be used to
certify the date on which the shareholder, or the beneficial owner on whose
behalf the shareholder dissents, acquired the shares (or an interest in them)
and to demand payment, and (iv) a copy of the provisions of the MBCA set forth
in Annex C with a brief description of the procedures to be followed under those
provisions. A shareholder who is sent such a notice and who wishes to assert
dissenters' rights must demand payment and deposit his or her certificates with
the Company within 30 days after such notice is given. Prior to the Effective
Time, a shareholder exercising dissenters' rights retains all other rights of a
shareholder. From and after the Effective Time, dissenting shareholders will no
longer be entitled to any rights of a shareholder, including, but not limited
to, the right to receive notice of meetings, to vote at any meetings or to
receive dividends, and will only be entitled to any rights of appraisal as
provided by the MBCA. If any such holder of Vaughn Common Stock shall have
failed to perfect or shall have effectively withdrawn or lost such right, his or
her shares of Vaughn Common Stock shall thereupon be deemed to have been
converted into the right to receive the Merger Consideration pursuant to the
Merger Agreement.
 
    After the Effective Time or upon receipt of a valid demand for payment,
whichever is later, the Company must remit to each dissenting shareholder who
complied with the requirements of the MBCA the amount the Company estimates to
be the fair value of such shareholder's shares of Vaughn Common
 
                                       30
<PAGE>
Stock, plus interest accrued from the Effective Time to the date of payment. The
payment also must be accompanied by certain financial data relating to the
Company, the Company's estimate of the fair value of the shares and a
description of the method used to reach such estimate, and a copy of the
applicable provisions of the MBCA with a brief description of the procedures to
be followed in demanding supplemental payment. If a dissenting shareholder
believes that the amount remitted is less than the fair value of such shares
plus interest, such dissenting shareholder may give written notice to the
Company of his or her own estimate of the fair value of the shares, plus
interest, within 30 days after the Company mails its remittance, and demand
payment of the difference.
 
    If the Company receives a demand from a dissenting shareholder to pay such
difference, it shall, within 60 days after receiving the demand, either pay to
the dissenting shareholder the amount demanded or agreed to by the dissenting
shareholder after discussion with the Company or file in court a petition
requesting that the court determine the fair value of the shares.
 
    The court may appoint one or more appraisers to receive evidence and make
recommendations to the court on the amount of the fair value of the shares. The
court shall determine whether the dissenting shareholder has complied with the
requirements of Section 302A.473 of the MBCA and shall determine the fair value
of the shares, taking into account any and all factors the court finds relevant,
computed by any method or combination of methods that the court, in its
discretion, sees fit to use. The fair value of the shares as determined by the
court is binding on all dissenting shareholders.
 
    Costs of the court proceeding shall be determined by the court and assessed
against the Company, except that part or all of the costs may be assessed
against any dissenting shareholders whose actions in demanding supplemental
payments are found by the court to be arbitrary, vexatious or not in good faith.
 
    If the court finds that the Company did not substantially comply with the
relevant provisions of the MBCA, the court may assess the fees and expenses, if
any, of attorneys or experts as the court deems equitable against the Company.
Such fees and expenses may also be assessed against any party in bringing the
proceedings if the court finds that such party has acted arbitrarily,
vexatiously or not in good faith, and may be awarded to a party injured by those
actions. The court may award, in its discretion, fees and expenses of an
attorney for the dissenting shareholders out of the amount awarded to such
shareholders, if any.
 
    A shareholder of record may assert dissenters' rights as to fewer than all
of the shares registered in such shareholder's name only if he or she dissents
with respect to all shares beneficially owned by any one beneficial shareholder
and notifies the Company in writing of the name and address of each person on
whose behalf he or she asserts dissenters' rights. The rights of such a partial
dissenting shareholder are determined as if the shares as to which he or she
dissents and his or her other shares were registered in the names of different
shareholders.
 
    Under Subdivision 4 of Section 302A.471 of the MBCA, a shareholder has no
right, at law or in equity, to set aside the approval of the Merger Agreement or
the consummation of the Merger except if such adoption or consummation was
fraudulent with respect to such shareholder or the Company.
 
FINANCING
 
    Allied, directly or indirectly through ADI, expects to make an equity
investment of up to $15 million in TAC, which amount will be used to partially
fund the payment of the cash consideration and expenses incurred in connection
with the Merger.
 
    Vaughn anticipates that approximately $50 million of additional financing
will be arranged through senior secured loans from a syndicate of banks led by
Fleet National Bank, N.A. ("Fleet") or a comparable financial institution (the
"Bank Lenders"). The proceeds of the loans will be used to provide the balance
of the funds required to consummate the Transactions, to pay fees and expenses
incurred in connection with the Merger, to refinance certain indebtedness under
existing credit facilities and to provide for capital expenditures, working
capital and the general business purposes of ADI and its subsidiaries. The
 
                                       31
<PAGE>
approximately $50 million of financing is in addition to ADI's existing $100
million senior credit facility led by Fleet.
 
    At the Effective Time, it is anticipated that ADI and Vaughn as co-borrowers
will enter into an amended and restated loan agreement with the Bank Lenders
providing for availability under a revolving credit facility of up to $40
million, a $55 million Term A facility, each maturing on December 31, 2003, and
a $55 million Term B facility maturing on December 31, 2004 (collectively, the
"Bank Facilities"). Loans under the Bank Facilities will bear interest, at the
option of ADI, at LIBOR or a base rate (the higher of (i) Fleet's prime rate and
(ii) the federal funds rate plus 1/2 of 1%), plus the applicable margin. It is
expected that loans under the revolving credit facility and Term A facility will
bear interest for an initial period at the applicable LIBOR rate plus 3%, and
initially loans under the Term B facility will bear interest at LIBOR plus
3.75%, and, thereafter, all loans under the revolving credit facility and the
term facilities will bear interest at applicable margin over LIBOR or the base
rate, as applicable, determined on the basis of Vaughn's ratio of total debt to
12 months trailing earnings before interest, taxes, depreciation and
amortization.
 
    It is also anticipated that at the Effective Time ADI will enter into a loan
agreement with Citicorp Mezzanine Partners, L.P. ("CMP") providing for an
approximately $15 million senior subordinated debt facility (the "Senior
Subordinated Facility") having a maturity date of June 30, 2007 and an annual
interest rate of 12%. Pursuant to an Amended and Restated Senior Subordinated
Loan Agreement between CMP and ADI, it is anticipated that CMP will be entitled
to receive warrants to purchase an amount when combined with existing warrants
held by CMP and Fleet Corporate Finance, Inc. ("FCF") that equals 10% of common
stock of Allied, par value $.01 per share ("Allied Common"), on a fully diluted
basis outstanding as of the Effective Time, at an exercise price of $.01 per
share. In the event that the new loan and the existing loans between ADI and CMP
are voluntarily prepaid in full prior to September 24, 1999, the number of
shares of Allied Common issuable upon exercise of the new warrants and warrants
previously issued to CMP and FCF by Allied shall automatically be reduced by
50%.
 
EXPENSES OF THE TRANSACTION
 
    As a result of the proposed Merger, the Company will incur various costs,
currently estimated at approximately $5.2 million, in connection with
consummating the Merger. These costs consist of (a) approximately $1.82 million
of professional fees and costs, (b) approximately $2.4 million of costs and
expenses relating to the financing of the Merger, (c) approximately $150,000 of
printing costs and filing fees and (d) approximately $830,000 of advisory fees
payable to EVEREN as financial advisor (inclusive of out-of-pocket expenses).
The exact timing, nature and amount of these costs are subject to change. See
"Special Factors--Opinion of the Company's Financial Advisor" and "Interests of
Certain Persons in the Merger--Fees Payable to Special Committee and Financial
Advisor" for a description of the fees to be paid to EVEREN in connection with
its engagement.

                              THE MERGER AGREEMENT
 
    The following is a brief summary of all material provisions of the Merger
Agreement. This summary does not purport to be complete and is qualified in its
entirety by reference to the Merger Agreement, which is attached to this Proxy
Statement as Annex A and is incorporated herein by reference.
 
THE MERGER
 
    The Merger Agreement contemplates that as soon as practicable after
satisfaction or waiver of all conditions to the Merger, Vaughn and TAC will file
a certificate of merger with the Secretary of State of the State of Minnesota
and make all other filings or recordings required by the MBCA in connection with
the Merger. 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 Minnesota or at
such later time as is specified in the certificate of merger. At the Effective
Time, TAC will be merged with and into Vaughn, with Vaughn being the Surviving
Corporation. 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 Vaughn and TAC, except as
provided under the MBCA.
 
THE SURVIVING CORPORATION
 
    At the Effective Time, the Articles of Incorporation of Vaughn will become
the Articles of Incorporation of the Surviving Corporation. At the Effective
Time, the by-laws of TAC will become the by-laws of the Surviving Corporation to
read as set forth in Exhibit A to the Merger Agreement until thereafter amended
as provided by law and such by-laws. From and after the Effective Time, all
directors of Vaughn designated by TAC will resign from the Board. Neither Vaughn
nor TAC has any present intention to change management of Vaughn. See
"--Directors and Officers of Vaughn Following the Merger." It is anticipated
that after the Effective Time, Vaughn will be reincorporated as a Delaware
corporation.
 
CONSIDERATION TO BE RECEIVED IN THE MERGER
 
    At the Effective Time, by virtue of the Merger and without any action on the
part of the holder of any shares of Vaughn Common Stock, each share of Vaughn
Common Stock issued and outstanding immediately prior to the Effective Time,
other than any Dissenting Shares (as defined below), will be canceled and will
be converted automatically into the right to receive an amount equal to $10.00
in cash, payable, without interest, to the holder of a share of Vaughn Common
Stock upon surrender of the certificate evidencing the share of Vaughn Common
Stock.
 
    Other than pursuant to the Willette Option Termination and Grant Agreement,
each option to purchase Vaughn Common Stock, outstanding immediately prior to
the Effective Time (whether or not the option is vested or exercisable) will be
canceled and in exchange therefor, each holder of an option to purchase Vaughn
Common Stock will receive a cash payment equal to the product of (a) the excess
of the cash consideration in the Merger over the exercise price of the option
multiplied by (b) the number of shares subject to the option, less any
applicable withholding taxes.
 
    At the Effective Time, except as described above, all shares of Vaughn
Common Stock outstanding immediately prior to the Effective Time will no longer
be outstanding and will automatically be canceled and retired and each holder of
a stock certificate representing shares of Vaughn Common Stock outstanding
immediately prior to the Effective Time will cease to have any rights with
respect thereto, except the right to receive the cash consideration in the
Merger, upon surrender of such certificates in accordance with the terms of the
Merger Agreement.
 
    No conversion will be made in respect of any shares of Vaughn Common Stock
as to which a Vaughn shareholder has elected to exercise dissenters' rights
until such time, if any, as such shareholder will have effectively lost
dissenters' rights.
 
                                       33
<PAGE>
    Shares which are issued and outstanding immediately prior to the Effective
Time and which are held by a holder who has not voted such shares in favor of
the Merger, who has delivered a written demand exercising dissenters' rights in
the manner provided by the MBCA and who, as of the Effective Time, has not
effectively withdrawn or lost such right to dissent, will not be converted into
a right to receive the cash consideration in the Merger ("Dissenting Shares").
The holders of Dissenting Shares will be entitled only to such rights as are
granted by Sections 302A.471 and 302A.473 of the MBCA. Each holder of Dissenting
Shares who becomes entitled to payment for such shares pursuant to the MBCA will
receive payment therefor from Vaughn in accordance with the MBCA; provided,
however, that (i) if any such holder of Dissenting Shares will have failed to
establish his entitlement to dissenters' rights as provided in the MBCA, (ii) if
any such holder of Dissenting Shares will have effectively withdrawn his demand
to exercise dissenters' rights or lost his right to payment for his shares under
the MBCA, or (iii) if neither any holder of Dissenting Shares nor Vaughn will
have filed a petition demanding a determination of the value of all Dissenting
Shares within the time provided in Sections 302A.471 and 302A.473 of the MBCA,
such holder will forfeit the right to exercise dissenters' rights for such
shares and each such share will be treated as if its holder had not elected
dissenters' rights and it had been converted, as of the Effective Time, into a
right to receive the cash consideration in the Merger, without interest thereon,
from the Surviving Corporation. Prior to the Effective Time, Vaughn will give
TAC prompt notice of any demands received by Vaughn for exercising of
dissenters' rights, and TAC will have the right to participate in all
negotiations and proceedings with respect to such demands. Prior to the
Effective Time, Vaughn will not, except with the prior written consent of TAC,
make any payment with respect to, or settle or offer to settle, any such
demands.
 
SURRENDER AND PAYMENT OF SHARES
 
    AST has been designated to act as paying agent for the benefit of the
holders of shares of Vaughn Common Stock in connection with the Merger to
receive the $10.00 per share cash consideration to which holders of shares of
Vaughn Common Stock will become entitled. TAC will deposit with AST the proceeds
of the Financing required in order to pay the Merger Consideration. Such funds
will be invested by AST as directed by the Surviving Corporation, and any
interest and other income resulting from such investment will be paid to the
Surviving Corporation. Promptly after the Effective Time, AST will send to each
holder of shares of Vaughn Common Stock outstanding immediately prior to the
Effective Time a Letter of Transmittal and instructions for use in effecting the
surrender of certificates. The Letter of Transmittal will specify that the
delivery will be effected, and that risk of loss and title will pass, only upon
delivery of the certificates representing shares of Vaughn Common Stock to AST.
 
    Each holder of shares of Vaughn Common Stock that have been converted into
the right to receive the cash consideration in the Merger, upon surrender to AST
of a certificate or certificates representing such shares, together with a
properly completed Letter of Transmittal covering such shares, will be entitled
to receive the cash consideration payable in respect of such shares. Until so
surrendered, each such certificate will, after the Effective Time, represent for
all purposes, only the right to receive such cash consideration. No interest
will be paid or will accrue on any cash payable as cash consideration in the
Merger.
 
    If any portion of the cash consideration is to be paid to a person other
than the registered holder of the shares of Vaughn Common Stock represented by
the certificate or certificates surrendered in exchange therefor, it will be a
condition to such payment that the certificate or certificates so surrendered
will be properly endorsed or otherwise be in proper form for transfer and that
the person requesting such payment will pay to AST any transfer or other taxes
required as a result of such payment to a person other than the registered
holder of such shares or establish to the satisfaction of the Surviving
Corporation or AST that such tax has been paid or is not applicable.
 
                                       34
<PAGE>
    At any time following the sixth months after the Effective Time, the
Surviving Corporation will be entitled to require AST to deliver to it any funds
made available to AST and not disbursed to holders of Vaughn Common Stock, and
thereafter such holders will be entitled to look to the Surviving Corporation
only as general creditors thereof for payment of their claim for cash.
Notwithstanding the foregoing, to the fullest extent permitted by law, neither
the Surviving Corporation nor AST will be liable to any holder of a share of
Vaughn Common Stock or to any other person for any Merger Consideration
delivered in respect of such share to a public official pursuant to any
applicable abandoned property, escheat or similar law.
 
    If any certificates representing shares of Vaughn Common Stock have not been
surrendered before the fifth anniversary of the Effective Time, any cash in
respect of such certificates will, to the extent permitted by applicable law,
become the property of the Surviving Corporation. In addition, if any cash in
respect of certificates representing shares of Vaughn Common Stock would, prior
to the fifth anniversary of the Effective Time, otherwise escheat to or become
the property of a governmental entity, such cash will, to the extent permitted
by applicable law, become the property of the Surviving Corporation.
 
    At and after the Effective Time, there will be no further registration of
transfers of Vaughn Common Stock on the records of Vaughn or its transfer agent.

<PAGE>
CERTAIN COVENANTS
 
    Pursuant to the Merger Agreement, Vaughn and TAC have agreed that:

the Effective Time, Vaughn will take such action as may be necessary to amend

Vaughn Common Stock to provide that such options shall be canceled at the
Effective Time and holders of such options shall only be entitled to the cash

NO SOLICITATION OF TRANSACTIONS
 
    The Merger Agreement provides that Vaughn will not (whether directly or
indirectly through advisors, agents or other intermediaries) authorize or
knowingly permit any of its or their officers, directors, agents,
representatives, advisors or subsidiaries to solicit, initiate or knowingly
encourage the submission of inquiries, proposals or offers from any third party
relating to (a) any acquisition of 5% or more of the consolidated assets of
Vaughn or of over 5% of any class of equity securities of Vaughn; (b) any tender
offer (including a self-tender offer) or exchange offer that if consummated
would result in any third party
 
                                       36
<PAGE>
beneficially owning 5% or more of any class of equity securities of Vaughn; (c)
any merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving Vaughn, other than the acquisition
of Vaughn by TAC and the Transactions; or (d) any other transaction, the
consummation of which would, or could reasonably be expected to, impede,
interfere with, prevent or materially delay the Merger or which would, or could
reasonably be expected to, materially dilute the benefits to TAC of the
Transactions (collectively, the "Transaction Proposals" and which, if
consummated, will be an "Acquisition Transaction"), or enter into or participate
in any discussions (except as may be necessary to inform a third party of the
no-solicitation provisions of the Merger Agreement or negotiations regarding any
of the foregoing), or furnish to any third party any information with respect to
the business, properties or assets of Vaughn in connection with the foregoing,
or otherwise cooperate in any way with, or knowingly assist or participate in,
facilitate or encourage, any effort or attempt by any third party to do or seek
any of the foregoing.
 
    The non-solicitation provisions contained in the Merger Agreement will not
limit or prohibit Vaughn from (a) furnishing information pursuant to an
appropriate and customary confidentiality agreement (which shall not be
substantially less restrictive than the Confidentiality Agreement entered into
by TAC in connection with the Merger) concerning Vaughn and its businesses,
properties or assets to a third party who has made an unsolicited Transaction
Proposal; (b) engaging in discussions or negotiations with such a third party
who has made an unsolicited Transaction Proposal; (c) taking a position on a
tender offer by a third party, as required by Rules 14e-2 and 14d-9 under the
Exchange Act (provided no such position will constitute a recommendation of such
transaction if it does not constitute a Transaction Proposal that the Vaughn
Board of Directors determines in good faith, and after consultation with and
advice from its financial advisors, is reasonably likely to be subject to
completion and would, if consummated, result in a Superior Acquisition Proposal)
or complying with its duties of disclosure under applicable state law; or (d)
following receipt of an unsolicited Transaction Proposal, failing to make,
modifying or withdrawing the recommendation of the Vaughn Board of Directors to
approve the Merger; provided, that Vaughn may undertake the actions set forth in
the foregoing clauses (a) through (d) only if and to the extent that the Vaughn
Board of Directors shall have concluded in good faith, after consulting with
financial advisors and considering the advice of outside counsel, that (i) such
action is required by the Vaughn Board of Directors in the exercise of its
fiduciary duties to the shareholders of the Company and (ii) such action is
reasonably likely to be subject to completion and would, if consummated result
in a Superior Acquisition Proposal; and provided, further, that the Vaughn Board
of Directors shall not take any of the foregoing actions referred to in clauses
(a) through (d) until after giving at least one business day's advance written
notice to TAC with respect to such actions. In addition, if the Vaughn Board of
Directors receives a Transaction Proposal, then the Company shall promptly
inform TAC in writing of the material terms of such proposal and the identity of
the third party making it. As of December 11, 1998, the Company ceased any
existing activities, discussions or negotiations with any parties with respect
to any Transaction Proposals. Any violation of the restrictions set forth in the
Merger Agreement by any director or executive officer of the Company or by any
investment banker, financial adviser, attorney, accountant, or other
representative of the Company shall be deemed to be a breach of the Merger

the breach remains uncured for 30 days after notice has been given, or (ii) if

the Merger Agreement of any of its representations, warranties or covenants);
(d) by either Vaughn or TAC, if there will be any law or regulation that makes

nonappealable; (e) by TAC, if (i) the Board of Directors of Vaughn will have
withdrawn or modified or amended, in a manner adverse to TAC, either its

           (i) Vaughn's Board of Directors notifies TAC that it has determined,
       in good faith, and after consultation with and advice from its financial
       advisors, that another Transaction Proposal is reasonably likely to be

       more favorable from a financial point of view to the Company's
       shareholders than the Merger;

       Superior Acquisition Proposal;
 
           (iii) Vaughn breaches any material representation, warranty,
       covenant, agreement or other obligation under the Merger Agreement and
       the breach continues without cure for 30 days after notice by TAC,
       another Transaction Proposal has been made and, within 12 months after
       termination of the Merger Agreement by TAC pursuant to the terms and
       conditions thereof, Vaughn consummates any Transaction Proposal (whether
       or not proposed prior to the Special Meeting and whether or not it
       involves the same third party making any other Transaction Proposal);
 
           (iv) Vaughn's Board of Directors withdraws or modifies its approval
       or recommendation of the Merger in a manner adverse to TAC, another
       Transaction Proposal has been made and, within 12 months after
       termination of the Merger Agreement by TAC pursuant to the terms and
       conditions thereof, Vaughn consummates any Transaction Proposal (whether
       or not proposed prior to the Special Meeting and whether or not it
       involves the same third party making any other Transaction Proposal); or
 
           (v) Vaughn fails to call a Special Meeting to consider and vote upon
       the Merger, another Transaction Proposal has been made and within 12
       months after termination of the Merger Agreement by TAC pursuant to the
       terms and conditions thereof, Vaughn consummates any Transaction Proposal
       (whether or not proposed prior to the Special Meeting and whether or not
       it involves the same third party making any other Transaction Proposal).
 
AMENDMENT AND WAIVER
 
    The Merger Agreement may be amended or its conditions precedent to closing
waived if, and only if, such amendment or waiver is in writing and signed by

changed its name to VAUGHN COMMUNICATIONS, INC. in 1987. Through November 16,
1998, the Company was engaged in two business segments: the Vaughn
Communications Division (the "Communications Division") and the Vaughn Products
Division (the "Products Division"). The Vaughn Communications Division is a
multimedia business services provider providing high volume videotape
duplication and digital media (compact disc and magnetic floppy disk)
replication for the corporate, educational and institutional user, accounting
for approximately 84% of the Company's sales in fiscal 1998. The Vaughn Products
Division was sold in November, 1998 (see "--Discontinued Operations--Vaughn
Products Division" below). The Vaughn Products Division was a manufacturer and
distributor of gifts, leather products, and custom designed soft goods sold by
gift shops and western stores, and accounted for approximately 16% of the
Company's sales in fiscal 1998.
 
    During the fiscal years ended January 31, 1998, 1997 and 1996, the
percentage of sales of the Communications Division and the Products Division as
compared to total sales of the Company were as follows:

    The Company's strategic objective is to grow and expand its business through
internal growth and acquisitions. (See "--Discontinued Operations--Vaughn
Products Division," "--Former Businesses" and "--Recent Acquisitions" below.)
The Company's principal executive offices are located at 5050 West 78th Street,
Minneapolis, Minnesota 55435, and its telephone number is (612) 832-3200.
 
VAUGHN COMMUNICATIONS DIVISION
 
    The Company's operations in the multimedia business services industry are
conducted through the Communications Division. The Communications Division
currently has videotape duplication facilities in Minneapolis (MN), Milwaukee
(WI), Phoenix (AZ), Tampa (FL), Portland (OR), Atlanta (GA), Dallas (TX),
Houston (TX), Raleigh (NC), Chicago (IL), Denver (CO) and Seattle (WA) and has a
facility in Fremont (CA), which replicates CDs and floppy disks. Additional
sales offices are located in St. Louis (MO), New York (NY), Irvine (CA), Orlando
(FL), Knoxville (TN), Baltimore (MD) and Ft. Lauderdale (FL). It serves markets
that are principally located in the United States.
 
    PRIMARY PRODUCTS AND SERVICES OF THE COMMUNICATIONS DIVISION
 
    GENERAL--The Communications Division is a major provider of multimedia
related business services for corporate, educational, and institutional
customers. The Company believes it is the second largest provider of videotape
duplication services for the business-to-business market. In addition to
videotape duplication, the Company provides digital media services through the
replication of CDs and magnetic disks ("floppies") for software developers and
computer equipment manufacturers. As part of its business, the Company also
provides various related services such as order fulfillment, video editing,
graphics design, international standards conversion, MPEG compression, and the
rental of video production and editing equipment on a short-term basis.
 
    VIDEOTAPE DUPLICATION SERVICES--The Company offers its videotape duplication
services to corporations that utilize videotape to promote their products,
instruct their customers on the use of their products, train their sales force
on new products or communicate with their employees. The Company has continued
to
 
                                       45
<PAGE>
expand its facilities for videotape duplication. On July 31, 1997 the Company
acquired certain assets of Dub South Acquisition, LLC ("Dub South"), a videotape
duplicator located in Atlanta, Georgia. The operations of Dub South were merged
with those of the Company's existing facility in Atlanta. In addition to
acquisitions, the Company spent approximately $1,900,000 to expand video
duplication facilities. Expansion has been financed by cash flow generated from
operations, equipment leasing and bank financing.
 
    DIGITAL MEDIA SERVICES--In order to better meet the current and long-term
needs of its business customers, the Company entered the digital media
replication business with the acquisition of Certified Media Corporation
("Certified") in July 1997. Certified, which commenced operations in 1986, was a
diskette duplicator in the California market serving the computer-based
entertainment market. In 1996, Certified entered the CD replication business. In
February 1998, the Company acquired a second Fremont, California-based digital
media duplicator, Copywise, Inc. The Company is currently in the final stages of
integrating these two businesses.
 
    The Company's digital media services are primarily focused on CD-ROM
products used to transfer data. The Company's digital media services are
currently sold to business customers which include: (i) computer equipment
manufacturers (e.g., modems, printers, scanners, etc.) that distribute driver
software programs to consumers; and (ii) software developers, such as game
authors.
 
    Going forward, the Company intends to focus its marketing efforts on
existing corporate customers that do, or could, utilize digital based media to
distribute information to customers and internal representatives. Examples
include aircraft manufacturers and industrial supply houses that distribute
parts catalogs to customers and insurance companies that distribute policy
information to agents on CD or floppy disks. As part of its overall digital
media services, the Company also provides a complete range of custom packaging,
fulfillment and design services.
 
    The Company intends to continue to invest in additional capacity for CD
replication as the demand warrants. In fiscal 1998, approximately $2,400,000 was
invested in expanding production capabilities.
 
    MANUFACTURING
 
    VIDEOTAPE DUPLICATION--The Company's videotape duplication facilities are
geographically distributed throughout the United States so that high volume
duplication can be accomplished at four facilities: Minneapolis (MN); Milwaukee
(WI); Atlanta (GA); and Tampa (FL). The Company also has eight other facilities
for smaller volume video manufacturing: Chicago (IL); Raleigh (NC); Dallas (TX);
Houston (TX); Phoenix (AZ); Denver (CO); Portland (OR); and Seattle (WA).
 
    The manufacturing process for videocassettes generally utilizes duplicating
machines that copy from a master in "real time" speed (i.e., the regular speed
of the videocassette being duplicated). In this process, high speed tape winders
are used to wind blank tape loaded to specific program lengths into video
shells. The video shells are then loaded into the duplicating machines which
receive the program being copied from a master transport. In addition, the
Company utilizes high speed machines, which allow it to duplicate a master 150
times faster than in "real time" speed. Real time duplicating machines are used
to duplicate videocassettes in standard play mode. High speed duplicating
machines are capable of duplicating videocassettes in either the extended play
mode or the standard play mode. The extended play format utilizes less tape than
regular speed machines require for the same program content.
 
    The entire video duplicating and winding process takes place in an
environment that is designed to eliminate airborne particles from the
duplicating process.
 
    Once a videocassette is loaded with tape and duplicated, the finished
product is checked to ensure that it conforms to strict audio and visual
standards established by the Company and the industry. The videocassettes are
then released to the packaging department where they are labeled, inserted into
sleeves
 
                                       46
<PAGE>
or boxes and processed through high speed shrink-wrapping machines for
distribution to the Company's customers.
 
    DIGITAL MEDIA SERVICES--The Company's production of CD products in Fremont
(CA) utilizes an injection molding process using high grade, optical quality
polycarbonate. The polycarbonate is pressed against a metal stamper to create a
replica of the CD Master at a rate of approximately one every four seconds. The
clear polycarbonate disc containing all of the data is then covered with a
metallic coating to provide for reflection of the reading laser beam in the CD
player. A thin layer of lacquer is applied over the metal to protect it and to
serve as a base for printing on the disc.
 
    As a result of a recent expansion, the Company has increased its annual
capacity to approximately 30 million units.
 
    LICENSES
 
    CD PRODUCTS--The Company, like most other CD manufacturers, uses patented
technology primarily under nonexclusive licenses from the holders of patents
which generally provide for the payment of royalties based upon the number of CD
units sold. On March 1, 1998, the Company signed a license agreement with U.S.
Philips Corporation.
 
    VIDEOTAPE PRODUCTS--The Company, like most other manufacturers of
videocassettes, uses patented technology under a nonexclusive license from the
holder of the patents (Macrovision Corporation) which provides for the payment
of various fees based on the number of videocassettes produced. The Company
entered into a licensed duplicator agreement with Macrovision Corporation dated
June 1, 1993.
 
    SIGNIFICANT CUSTOMERS
 
    The Communications Division sells to more than 6,500 accounts in any given
year. Approximately 13% of its sales come from ten customers, none of which
amount to more than 3% of net sales.
 
    Illustrative of the Communications Division's video duplication customers
are companies that use videotape to promote their products or instruct their
customers on the use of their products, financial service companies which
produce videotapes to present new financial products to sales personnel and
customers, high technology companies which use videotapes to train sales and
service personnel and corporations with many employees or locations that wish to
communicate a significant Company development to all employees simultaneously.
Such high volume customers are generally those who need 100 or more duplicate
videotapes reproduced, addressed to individual locations and forwarded for
delivery, often within a few hours or on an overnight basis.
 
    Illustrative of the Company's CD replication customers are software
developers and computer hardware manufacturers.
 
    MARKETING
 
    The Communications Division markets its products nationally through the use
of 45 field sales personnel who operate throughout the United States. To a
lesser degree, the Company also uses advertising in trade publications and
participation in trade shows.
 
    SEASONALITY
 
    The Communications Division's products are used consistently throughout the
year except for a slight rise in demand in September, October, and November to
supply extra requirements to customers for the holiday selling season.
 
                                       47
<PAGE>
    COMPETITION
 
    Though it is not possible to reliably state the Communications Division's
relative position in the absence of published statistics, based upon data
generated by its own management, the Company believes it is one of the largest
duplicators of videotape for the non-theatrical, non-music video segment of the
U.S. market. This market is comprised of exercise, educational, corporate,
promotional and instructional videos, etc. The Company does not hold a dominant
position in the CD replication industry.
 
    The primary competitive factors in the videotape duplication and CD
replication business are price, quality of service and range of products. The
Communications Division attempts to compete by offering high-volume videotape
duplication services, at a competitive price, emphasizing service and customer
support.
 
    The Company's principal competitors are Allied Digital Technologies
(formerly Allied Film and Video Company) and The Duplication Factory. The video
duplication business is highly competitive, not only with these competitors, but
also with many smaller duplicators.
 
    The Company believes that its regional locations, its wide range of product
offerings, and national marketing capabilities are competitive advantages over
many others in the industry. While selling prices have been declining in recent
years as competitors continue to seek market share by lowering prices, the
Company has been reasonably successful in maintaining its margins by lowering
its material costs and achieving unit volume increases.
 
DISCONTINUED OPERATIONS--VAUGHN PRODUCTS DIVISION
 
    On November 16, 1998, the Company sold substantially all of the assets of
its Products Division to Gift Connections, Inc. (the "Buyer") for a selling
price of $1,432,775 which included $300,000 of cash, a short-term note in the
principal amount of $932,775 and the assumption of $200,000 of liabilities. The
Products Division was engaged in the manufacture and sale of a line of soft
goods, including custom-designed, silk-screened T-shirts and sweatshirts,
souvenir leather products, and gift items sold primarily to retail merchants
located in the United States and Canada. The Products Division's manufacturing
facilities were located in the Company's Minneapolis, Minnesota plant where it
produced a line of over 200 leather items such as billfolds, purses, and
personal accessory items, and in Seattle, Washington, where it designed and
produced its soft goods products. The Products Division's corporate headquarters
were also located in Seattle. The gift products were sold at wholesale prices
for resale, primarily by gift shops, and were marketed under the "Bloom
Brothers" and "Indian Arts and Crafts" names. The Products Division employed 52
manufacturing, sales and administrative personnel. The Buyer reemployed
substantially all of these employees.
 
FORMER BUSINESSES
 
    The Company originally operated as a manufacturer of seasonal decorative
displays. In addition to this business, the Products Division business and its
current business segment, from 1986 through 1991 the Company also operated six
radio broadcasting stations.
 
    In 1990 the Company began to focus its corporate and personnel resources on
the video duplication business operated by the Communications Division. In 1990
and 1991, the Company sold its radio station interests and its audio and video
equipment sales and engineering businesses.
 
    By March 1, 1994, the Company sold its remaining seasonal decorative display
businesses to a Minnesota based corporation. These businesses previously
occupied approximately 5,000 square feet of the Company's principal
manufacturing plant in Minneapolis, Minnesota and its 12,000 square foot
manufacturing plant in Tampa, Florida, and employed 21 manufacturing, sales and
administrative personnel.
 
                                       48
<PAGE>
BACKLOG
 
    Order backlog is not generally a significant factor in the Company's
business. The Company relies primarily on current selling efforts coupled with
near-term delivery or performance.
 
EMPLOYEES
 
    On November 30, 1998, the Company had 786 employees, including 134 in sales
and marketing, 585 in manufacturing and 67 in executive, finance and
administrative positions. Seventy-nine of the Company's manufacturing and
clerical employees are part-time employees. The Company's employees are not
represented by a union. The Company considers its employee relations to be
satisfactory.
 
COMPLIANCE WITH ENVIRONMENTAL LAWS
 
    The costs associated with the Company's compliance with Federal, state and
local environmental laws are minimal. For these reasons, the Company's
compliance with such laws does not have a material effect on its capital
expenditures, earnings or its competitive position in the marketplace.
 
RECENT ACQUISITIONS
 
    PURCHASE OF COPYWISE, INC.
 
    On February 1, 1998, the Company completed the acquisition of the assets of
Copywise, Inc. ("Copywise"), a floppy disk replicator located in Fremont,
California. The acquisition was accounted for by the purchase method of
accounting. Goodwill associated with the purchase will be amortized over 15
years. The noncontingent purchase price was approximately $1,670,000 in cash and
the assumption of approximately $667,000 of liabilities. The purchase price may
be increased by an additional $1,560,000 depending upon the attainment of
certain financial objectives by the acquired business through January 31, 2000.
 
    PURCHASE OF CERTIFIED MEDIA CORPORATION
 
    On July 31, 1997, the Company completed the acquisition of certain assets
and assumed certain liabilities of Certified, a California Subchapter S
Corporation. The Company accounted for the acquisition as a purchase.
 
    The noncontingent price of $5,500,000 was paid to the four shareholders of
Certified. The Company paid $2,800,000 in cash, issued 171,210 shares of Vaughn
Common Stock valued at approximately $7.01 per share ($1,200,000 in the
aggregate), equal to the average closing sale price on the Nasdaq for the 10
days prior to July 31, 1997, and issued $1,500,000 of long-term debt to the
Sellers. The long-term debt is payable in five equal annual installments
starting on July 31, 1998. The interest rate is at the prime rate.
 
    The purchase price may be increased to a maximum of $7,500,000 depending
upon the financial performance of Certified through January 31, 1999.
 
    The Company also entered into a five-year consulting and noncompete
agreement with Alan Gill, the former president of Certified. The agreement calls
for annual payments of $86,641. In addition, noncompete agreements signed with
the remaining three shareholders for terms of three to five years call for
annual payments ranging from $906 to $8,641.
 
    FINANCING THE ACQUISITION--The Company used its revolving credit facility to
fund the $2,800,000 cash portion of the purchase price. The credit facility
provided a $2,800,000 term loan due July 31, 2002, payable in consecutive
quarterly principal installments of $140,000 commencing October 31, 1997, plus
interest at the bank's prime rate.
 
                                       49
<PAGE>
    DESCRIPTION OF CERTIFIED MEDIA'S BUSINESS--Certified Media's business
consists primarily of the replication of CDs utilizing an injection molding
process. Located in Fremont, California, Certified's customers include computer
software developers and computer hardware manufacturers. Certified Media's
business has been merged with the Communications Division.
 
    The Company believes that the Certified acquisition has assisted the
Company's transformation from a videotape duplication specialist to a total
media solutions provider and that using the Company's existing sales force will
provide significant growth for the business acquired through the acquisition of
Certified.
 
    For Certified's fiscal years ended December 31, 1996 and 1995, it had annual
sales of $4,459,000 and $7,958,000, respectively. Net income (loss) for the
respective periods was ($1,189,000) and $1,047,000. The net income numbers do
not include the effect of any income taxes since Certified was a Subchapter S
Corporation.
 
    PURCHASE OF DUB SOUTH
 
    On July 31, 1997, the Company acquired certain of the assets and assumed
certain of the liabilities of Dub South, a Georgia limited liability company.
The Company accounted for the acquisition as a purchase.
 
    The noncontingent purchase price for the assets included approximately
$311,000 in cash and the assumption of approximately $439,000 of liabilities.
The purchase price may be increased by an additional $1,200,000, depending on
profit performance through January 31, 2002.
 
    Dub South is a regional videotape duplicator with its facility in Atlanta,
Georgia. Its business is substantially similar to the videotape duplication
business of the Communications Division, and its operations have been merged
into the Company's pre-existing facilities in Atlanta.
 
    For Dub South's fiscal year ended December 31, 1996, sales were $1,907,000
and had a net loss of $520,000.
 
    MERGER OF SATASTAR CORPORATE SERVICES, INC.
 
    Pursuant to a Plan and Agreement of Merger dated June 7, 1996, on June 28,
1996 Satastar Corporate Services, Inc. (dba PVS Corporate Services)
("Satastar"), an Illinois corporation, was merged into the Company. The Company
accounted for the transaction as a pooling of interests. The merger was effected
by the issuance of 165,357 shares of Vaughn Common Stock valued at $13.75 per
share, or approximately $2,274,000 in the aggregate, in exchange for all the
common stock of Satastar.
 
    The Company also entered into employment and noncompete agreements with the
former owners of Satastar. The agreements are for terms ranging from two to
three years and call for compensation of $130,000 to $162,000 per year.
 
    DESCRIPTION OF SATASTAR'S BUSINESS--Satastar is a regional videotape
duplicator whose business, with the exception of specific customer identity, is
substantially similar to the videotape duplication business of the Company's
Communications Division of which Satastar has become part. Satastar has a
videotape duplication facility in Chicago, Illinois, and the Company merged its
pre-existing facility in Chicago into that of Satastar.
 
    For Satastar's years ended December 31, 1996 and 1995, it had annual sales
of $4,056,000 and $3,868,000, respectively. Net income for the respective
periods was $102,000 and $342,000.
 
    At the time of the merger, Satastar had 39 employees, including 3 in sales,
10 in administration and support, and 26 in operations. A majority of these
persons are currently employees of the Communications Division. These employees
are not represented by a union. The Company considers Satastar's employee
relations to be satisfactory, and there have been no work stoppages.

    PURCHASE OF CENTERCOM AND RELATED TRANSACTIONS
 
    On April 4, 1995, the Company completed the acquisition of all of the
capital stock of Centercom, Inc., a Wisconsin corporation, and Centercom South,
Inc., a Florida corporation (collectively, "Centercom") pursuant to a Stock
Purchase Agreement of even date (for the purposes of this section, the "Purchase
Agreement"). The effective date of the acquisition is April 1, 1995. The Company
accounted for the acquisition as a purchase.
 
    The purchase price for the capital stock of Centercom was $6,420,000, which
was paid equally to the two equal former shareholders of Centercom, Jeffrey
Johnson and Robert Harmon (for purposes of this subsection referred to as the
"Sellers"). The Company paid $5,250,000 in cash and issued 180,000 shares of
Vaughn Common Stock, valued at $6.50 per share ($1,170,000 in the aggregate),
equal to the closing sale price of the stock on Nasdaq on April 3, 1995.
Pursuant to the terms of the Purchase Agreement, the Sellers have been elected
as directors of the Company and appointed as members of the Company's Audit
Committee. However, Mr. Harmon resigned as a director of Vaughn for personal
reasons effective as of June 23, 1998.
 
    The Sellers receive $100,000 each per year for a period of seven years under
consulting and noncompete agreements. In addition, the Company has entered into
two ten-year leases for the videotape duplication facilities totaling
approximately 38,000 square feet owned by a partnership of the Sellers in
Milwaukee, Wisconsin, at an aggregate annual net rent of $186,353 for the first
three years and $199,225 for the remaining seven years of the lease term.
Management of the Company believes that the facilities leased from the Sellers
are necessary for its videotape duplication business and that the lease terms
and conditions are no less favorable to the Company than could be obtained from
an unrelated third party (see "Description of Centercom's Business" below).
 
    FINANCING FOR THE ACQUISITION--The Company borrowed the cash consideration
for the Centercom acquisition from a bank under a loan agreement. The loan
agreement provided a $5,000,000 term loan due March 31, 2000, payable in
consecutive quarterly principal installments of $250,000 commencing July 1,
1995, plus interest at one-quarter percent over the bank's prime rate. The Loan
Agreement also provided a revolving credit facility of up to $8,000,000. On
February 1, 1996, the Company entered into an amended agreement with its bank
which reduced the interest rate on the term loans to the prime rate.
 
    DESCRIPTION OF CENTERCOM'S BUSINESS--Centercom is a national videotape
duplicator whose business, with the exception of specific customer identity and
geographic concentration, is substantially similar to the videotape duplication
business of the Communications Division of which Centercom has become a part.
Centercom has videotape duplication facilities in Milwaukee, Wisconsin, Chicago,
Illinois and Tampa, Florida. The Company has merged its preexisting facilities
in Milwaukee, Chicago and Tampa into those of Centercom. Centercom, Inc. and
Centercom South, Inc. initially following the acquisition operated as
wholly-owned subsidiaries of the Company, but are now merged into the Company.
 
    For Centercom's fiscal years ended June 30, 1994 and 1993, it had annual
sales of $8,700,000 and $7,700,000, respectively. Net income for the same
periods was $645,000 and $412,000.
 
    Centercom's operations involve the use of several hundred real time
videotape duplicating machines and three high-speed (150 times real time rates)
duplicating machines similar to those used by the Company.
 
    The Company believes that the Centercom acquisition has enabled the Company
to be a dominant competitor in the Milwaukee market, enhanced the Company's
already dominant position in the Tampa market and increased the Company's
presence in the Chicago market.

    PURCHASE OF ADVANCED AUDIO/VIDEO PRODUCTIONS, INC.
 
    Pursuant to a Purchase and Sale Agreement dated December 29, 1995, on
January 1, 1996 the Company acquired substantially all the assets and assumed
substantially all the liabilities of Advanced Audio/Video Productions, Inc.
("Advanced Video"), a Colorado corporation. The Company accounted for the

starting January 5, 1997, plus interest at the prime rate adjusted on the
anniversary date.
 
    Advanced Video is a regional videotape duplicator with its facility located
in Denver, Colorado. Its business is substantially similar to the videotape
duplication business of the Company's Communications Division of which Advanced
Video has become a part.
 
    For Advanced Video's fiscal year ended December 31, 1995, it had annual
sales of $1,204,000 and net income of $60,000.
 
    PURCHASE OF INDIAN ARTS AND CRAFTS, INC.
 
    Pursuant to a Purchase and Sale Agreement dated January 31, 1996, the
Company acquired substantially all the assets and assumed substantially all the
liabilities of IAAC, a Washington corporation. The Company accounted for the
acquisition as a purchase.
 
    The purchase price of approximately $2,332,000 was paid to the five
shareholders of IAAC (for purposes of this subsection, the "Sellers"). The
Company paid approximately $82,000 in cash, issued 145,138 shares of Vaughn
Common Stock valued at $8.6125 per share ($1,250,000 in the aggregate), equal to
the average closing sale price of the stock on Nasdaq for the 10 days prior to
January 31, 1996, and issued $1,000,000 of long-term debt to the Sellers. The
long-term debt consists of two promissory notes: one in the principal amount of
$250,000 payable in three equal annual installments beginning January 31, 1997,
and the other in the principal amount of $750,000 payable in seven equal annual
installments starting on January 31, 1997. The interest rate on both notes is
8.5% per annum.
 
    The Company also entered into a three-year employment agreement with Howard
Lowen, the president and largest shareholder of IAAC. This employment agreement
terminated in July, 1998. In addition, the Company entered into two leases with
the Sellers. One lease is for a production facility in Seattle totaling
approximately 42,300 square feet at an aggregate annual rent of $250,000. The
term of this lease is 44 months starting February 1, 1996. The second lease is
for a sales office in Anchorage, AK (1,400 square feet) at an annual rental of
$14,400 and has a three-year term. Management of the Company believed that the
facilities leased from the Sellers were necessary for the business of the
Products Division and that the terms of the leases were no less favorable to the
Company than could be obtained from an unrelated third party. The leases were
assumed by the buyer of the Products Division. See "Business and Operations of
Vaughn--Discontinued Operations--Vaughn Products Division" above.
 
    FINANCING FOR THE ACQUISITION--The Company used its revolving credit
facility to fund the $82,000 cash portion of the purchase price. To fund the
anticipated increase in working capital needs, the Company entered into an
Amended and Restated Loan Agreement with a bank on February 1, 1996 (the
"Amended Agreement"). The Amended Agreement increased the total credit facility
from $13,000,000 to $17,000,000 and provided for long-term financing to finance
acquisitions and equipment purchases, and a revolving credit facility to finance
working capital. The interest rate on the long-term debt and the revolving debt
is at the prime rate.

    DESCRIPTION OF IAAC'S BUSINESS--IAAC's business consists primarily of the
manufacture and sale of gift and souvenir products. Its principal products are
custom-designed soft goods, including T-shirts, sweatshirts and hats sold
primarily in Alaska and the Pacific Northwest. The Company has an art department
which develops custom designs that are silk-screened on apparel and then sold to
retailers by direct salespeople or independent manufacturers' representatives.
IAAC also resells other gift and souvenir products through the same sales
channels. IAAC was merged into the Products Division, and the Company moved the
majority of the operations of the Products Division to Seattle during fiscal
1997.
 
    For IAAC's fiscal years ended December 31, 1995 and 1994, it had annual
sales of $7,543,000 and $7,593,000, respectively. Net income for the same
periods was $227,000 and $360,000, respectively.
 
PROPERTIES
 
    The Company owns its executive and administrative offices and principal
manufacturing plant consisting of approximately 67,000 square feet located on a
4.1 acre site at 5050 West 78th Street, Minneapolis, Minnesota. Approximately
2,500 square feet is devoted to packaging and warehousing of the Products
Division's products and raw materials. This space is currently under lease to
the buyer of the Products Division. See "Business and Operations of
Vaughn--Discontinued Operations--Vaughn Products Division" above. Approximately
57,600 square feet is used for the Communications Division's separate
administrative and sales offices, showrooms, videotape duplication, shipping,
warehouse and handling. The remaining space of approximately 4,400 square feet
houses the Company's executive and administrative offices. These facilities
include a separate adjacent building of approximately 10,600 square feet. See
the Notes to the audited financial statements of the Company incorporated by
reference for a description of the mortgage term loan to the Company secured by
these facilities.
 
    The Company leases its Communications Division's facilities in Fremont,
California; Milwaukee, Wisconsin; Phoenix, Arizona; Tampa and Orlando, Florida;
Portland, Oregon; Atlanta, Georgia; Dallas, Texas; Houston, Texas; Raleigh,
North Carolina; Chicago, Illinois; Seattle, Washington; and Denver, Colorado for
sales offices and manufacturing, totaling approximately 280,000 square feet
under leases expiring from 1998 through 2003, at a current total annual rental
of approximately $1,560,000.
 
    The Company is presently utilizing approximately 75% of its manufacturing
plant capacity measured on a five-day week/three shift per day basis. Production
capacity, however, can be expanded by adding additional personnel or acquiring
additional manufacturing equipment. Management believes its manufacturing
facilities are generally sufficient for the Company's immediately foreseeable
needs.
 
LEGAL PROCEEDINGS
 
    There are no legal proceedings pending against or involving the Company or
its properties which, in the opinion of management, will have a material adverse
effect upon the Company's financial position or results of operations.

NOTE C--ACQUISITIONS
 
    On February 1, 1998, the Company completed the acquisition of the assets of
Copywise, a floppy disk replicator located in Fremont, California. The
acquisition will be accounted for by the purchase method of accounting. Goodwill
associated with the purchase will be amortized over 15 years. The noncontingent
purchase price was approximately $1,670,000 of cash and the assumption of
approximately $667,000 of liabilities. The purchase price may be increased by an
additional $1,560,000 depending upon the attainment of certain financial
objectives by the acquired business through January 31, 2000.
 
    In July, 1997, the Company acquired certain assets and assumed certain
liabilities of Certified, a CD replicator located in Fremont, California. The
initial purchase price was $5,500,000, including $2,800,000 of cash, 171,210
shares of Vaughn Common Stock valued at $1,200,000, and long-term debt to the
sellers of $1,500,000. The purchase price may be increased to a maximum of
$7,500,000 depending upon Certified's attainment of specific financial
objectives through January 31, 1999. Goodwill recorded in this transaction is
being amortized over 15 years using the straight-line method.
 
    In July, 1997, the Company also acquired certain assets of Dub South, a
videotape duplicator located in Atlanta, Georgia. The noncontingent purchase
price included $311,000 of cash and the assumption of approximately $439,000 of
liabilities. The purchase price may be increased by an additional $1,200,000,
depending on the profit performance for the next five years. There was no
goodwill recorded on this transaction.
 
    All the acquisitions have been accounted for by the purchase method of
accounting, and the consolidated financial statements for the period ended July
31, 1998, reflect the purchase of the businesses and include any results from
operations subsequent to the closing date of the respective transactions.

NOTE D--DISCONTINUED EARNINGS
 
    During the third quarter of 1998, the Company developed a plan to dispose of
the assets and operations of the Products Division, the operating unit of the
Company involved in the manufacture and sale of gift and souvenir products. The
financial statements have been restated to reflect the Products Division's
results of operations as discontinued operations, and the assets of the division
were restated to reflect their estimated realizable value, which resulted in a
pretax loss of approximately $4,123,000. The estimated realizable value was
based upon an offer the Company received to purchase the business. On November
16, 1998, the Company reached an agreement with a buyer for the sale of the
assets and operations of the Products Division. The selling price of $1,432,775
included $300,000 of cash, a short-term note of $932,775 and the assumption of
$200,000 of liabilities by the buyer.
 
    Summarized results of operations and financial position data of discontinued
operations were as follows (in thousands):

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATION
 
    Vaughn's consolidated financial statements represent the combined results of
the Company's continuing business, the Communications Division, which represents
84% of the Company's sales in fiscal 1998, and its discontinued gift products
business, the Products Division. The Communications Division is a national
multimedia business services company providing videotape duplication and digital
media (CD and magnetic floppy disk) replication and related services throughout
the United States.
 
CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS
 
    Statements in this proxy statement and other written reports and oral
statements made from time to time by the Company may contain so-called
"forward-looking statements," all of which are subject to risks and
uncertainties. These forward-looking statements are identified by their use of
words such as "expects," "plans," "will," "estimates" and other words of similar
meaning, and by the fact that they do not relate strictly to historical or
current facts. These statements are likely to address the Company's growth
strategy, financial results, or acquisition strategies. One must carefully
consider any such statement and should understand that many factors could cause
actual results to differ from the Company's forward-looking statements. These
factors include inaccurate assumptions and a broad variety of other risks and
uncertainties, including some that are known and some that are not. No
forward-looking statement can be guaranteed and actual results may vary
materially.
 
YEAR 2000 COMPLIANCE
 
    Computer programs which were written using two digits (rather than four) to
define the applicable year may recognize a date using "00" as the year 1900
rather than the year 2000, a result commonly referred to as the "Year 2000"
problem. This could result in a system failure, or miscalculation.
 
    In 1997, Vaughn initiated a program to evaluate whether internally developed
and purchased computer programs may experience operational problems when the
year 2000 is reached. The scope of this effort included internal computer
systems and supplier capabilities. The Company is completing this review to
determine whether its computer programs are Year 2000 compliant, as well as
determining what remedial action is required, and the costs associated with
required modification or replacements. A significant amount of information has
been collected and analyzed, however, the process will not be completed until
calendar year 1999. The Company plans to complete all remediation efforts for
its systems prior to the year 2000. Based on its evaluation to date, management
believes that, while the Company will incur internal and possibly external costs
to address the Year 2000 problem, such costs will not have a material impact on
the operations, cash flows, or financial condition of Vaughn.
 
RESULTS OF OPERATIONS--NINE MONTH PERIOD ENDED OCTOBER 31, 1998 COMPARED TO NINE
  MONTH PERIOD ENDED OCTOBER 31, 1997
 
    DISCONTINUED OPERATIONS
 
    On November 16, 1998, the Company sold the Products Division for
approximately $300,000 cash paid at closing, a short-term note in the principal
amount of $932,775 and the assumption of $200,000 of liabilities. The Products
Division, which was engaged in the sale and manufacture of gift and souvenir
products, no longer met the Company's long-term strategic direction. The
transaction, which involved the sale of selected assets including approximately
$758,000 of accounts receivable, $3,880,000 of inventory, $380,000 of fixed
assets and $406,000 of other assets, and the assumption of approximately
$200,000 of liabilities by the buyer, resulted in a pretax loss of approximately
$4,123,000. The sale of the Products Division has been treated as a discontinued
operation, and prior financial information has been restated to reflect this
treatment.
 
                                       61
<PAGE>
    For the first nine months of fiscal 1999, the Products Division's net sales
had declined 14.5% from $10,708,000 in fiscal 1998 to $9,160,000 in fiscal 1999.
The decrease was attributed in part to a transition in sales personnel. The
pretax income for the first nine months of fiscal 1999 of $72,000 was a 46.3%
decline from the previous year's pretax income of $134,000.
 
    CONTINUING OPERATIONS
 
    On February 1, 1998, the Company acquired the assets of Copywise, a floppy
disk replicator located in Fremont, California, for a non-contingent purchase
price of approximately $1,670,000 cash and the assumption of approximately
$667,000 of liabilities. The acquisition has been accounted for as a purchase,
and the operating results are included in the Company's results as of the date
of acquisition. The operations of Copywise have been merged into the Company's
pre-existing facility in Fremont.
 
    For the first nine months net sales from continuing operations increased 32%
from $45,593,000 in fiscal 1998 to $60,234,000 in fiscal 1999. The increase is
attributable to a 12% increase in sales from pre-existing operations, and the
inclusion of sales from the Company's acquisitions of Copywise and Certified
Media (which was acquired on July 31, 1997).
 
    Gross margins have decreased slightly from the previous year. Year-to-date
gross margins have declined from 34.1% to 33.1%. The decrease is due to the
lower margins being realized on the sale of CD replication.
 
    Operating expenses as a percentage of sales for the first nine months of
fiscal 1999 have declined to 25.2% from 26.3% for the first nine months of
fiscal 1998. The decrease is a result of sales growth which increased the
leveraging of fixed costs and continued efforts to control expenses.
 
    Interest expense for the first nine months of fiscal 1999 has increased 45%
from the previous year, from $871,000 in the first nine months of fiscal 1998 to
$1,268,000 in the first nine months of fiscal 1999. The increase was due to
additional borrowings associated with the acquisitions of Certified Media and
Copywise and increased working capital borrowings needed to support the sales
growth. For the first nine months of fiscal 1999 net income from continuing
operations increased 28% from $1,609,000 in the first nine months of fiscal 1998
to $2,058,000 in the first nine months of fiscal 1999.
 
RESULTS OF OPERATIONS--YEAR ENDED JANUARY 31, 1998 COMPARED TO YEAR ENDED
  JANUARY 31, 1997
 
    DISCUSSION OF COMBINED OPERATIONS BEFORE SELL-OFF OF PRODUCTS DIVISION
 
    The Company's net sales, including net sales provided by acquired business
from the date of acquisition, increased 8% in fiscal 1998 to approximately
$74,488,000. The increase was attributable to a 13% increase in net sales from
the Communications Division which offset an 11% decrease in net sales from the
Products Division. Gross margins increased slightly in fiscal 1998, from 31.5%
to 31.9%. Selling, general and administrative expenses were approximately
$19,093,000, a 12% increase over the previous year, and represent 25.6% of net
sales, compared to 24.7% the previous year. Net interest expense increased
slightly from approximately $1,237,000 in fiscal 1997 to $1,295,000 in fiscal
1998. Pretax income in fiscal 1998 was approximately $3,338,000, a 4% decrease
from the prior year. The decrease was due to a $532,000 decrease in pretax
income from the Products Division (pretax income of $161,000 in fiscal 1997
compared to a pretax loss of $371,000 in fiscal 1998). This decrease was
partially offset by a 12% increase in pretax income from the Communications
Division. The Company's effective tax rate remained at approximately 42%.
Consolidated net income declined 4%, from approximately $2,015,000 in fiscal
1997 to approximately $1,938,000 in fiscal 1998.
 
    COMMUNICATIONS DIVISION--CONTINUING OPERATIONS
 
    The Communications Division's strategy is to grow through internally
generated growth and through strategic acquisitions. The Company continued to
implement this strategy in fiscal 1998 with two strategic
 
                                       62
<PAGE>
acquisitions. In order to better meet the current and long-term needs of its
business customers, the Company entered the digital media replication business
with the acquisition, on July 31, 1997, of Certified, a CD replicator located in
Fremont, California. The noncontingent purchase price of $5,500,000 included
$2,800,000 in cash, 171,210 shares of Vaughn Common Stock valued at $1,200,000
and a $1,500,000 note to the sellers. The purchase price may be increased an
additional $2,000,000 based upon Certified's attaining certain financial
objectives. The Company believes it is well positioned for strong sales growth
and market penetration in this business as it intends to capitalize on its
existing sales force to sell this new product offering. Also on July 31, 1997,
the Company acquired certain of the assets of Dub South, a videotape duplicator
located in Atlanta, Georgia. The operations of Dub South were merged into the
Company's pre-existing facility in Atlanta. The noncontingent purchase price of
$750,000 included approximately $311,000 in cash and the assumption of $439,000
of liabilities. The purchase price may be increased by an additional $1,200,000
depending on the financial performance of Dub South. Both acquisitions have been
accounted for as purchases and their operating results are included in the
Company's results for the period subsequent to their acquisition date.
 
    The Communications Division's net sales increased 13% in fiscal 1998, from
approximately $55,000,000 in fiscal 1997 to approximately $62,300,000. The net
sales generated due to the acquisition of Certified and a 3% increase in the
sales from pre-existing facilities contributed to the sales growth. The Company
believes that although the growth of videotape duplicators has slowed, there
continues to be opportunities for growth in this market and there are
significant growth opportunities in the CD replication market, although there
can be no assurances that such growth will be experienced by the Company.
 
    The gross profit margins increased from 32.9% in fiscal 1997 to 33.5% in
fiscal 1998. The improvement was the result of cost control measures instituted
at the beginning of the year and continued leveraging of fixed expenses. The
Company expects to be able to maintain its profit margins by continuing to
improve efficiencies, the continued leveraging of fixed costs with increased
volume, and continuing to utilize low cost providers of raw materials.
 
    Selling, general and administrative expenses in fiscal 1998 were up 17% over
fiscal 1997 and represented 25.8% of net sales in fiscal 1998 compared to 25% in
fiscal 1997. The increase in selling, general and administrative expenses
reflects additional expenses associated with the acquisitions previously
discussed, including goodwill amortization and noncompete payments.
 
    Net interest increased to approximately $1,107,000 in fiscal 1998, an
increase of approximately $76,000 from the previous year. The increase was due
to interest associated with additional acquisition debt.
 
    Pretax income for the Communications Division was $3,709,000, a 12% increase
over the previous year. Excluding the results of the acquisition of Certified,
pretax income increased by 15% in fiscal 1998. Certified's operating profit
after adding back amortization expense and interest on the acquisition debt was
approximately $260,000.
 
    The Company invested approximately $4,432,000 on equipment and facilities to
expand its production capacity. This investment included approximately
$2,400,000 spent to expand the CD replication capacity. The investment in
capital equipment was funded by long-term financing and internally generated
funds.
 
    PRODUCTS DIVISION--DISCONTINUED OPERATIONS
 
    The Products Division, which manufactures and sells gift products throughout
the United States, struggled during fiscal year 1998. A decrease in sales from
the prior year, a change in senior management at mid-year, and continuing
difficulties in consolidating its operations in Seattle all contributed to the
disappointing results.
 
    Net sales of approximately $12,196,000 were an 11% decrease from the prior
year. The decrease in sales also resulted in a decrease in the leveraging of
fixed costs, resulting in a reduction in gross margins
 
                                       63
<PAGE>
from 26% in fiscal 1997 to 23% in fiscal 1998. Although selling, general and
administrative expenses decreased from approximately $3,239,000 in fiscal 1997
to approximately $3,014,000, it was not enough to offset the decrease in net
sales and gross margins, and pretax income declined from $161,000 in fiscal 1997
to a pretax loss of $371,000 in fiscal 1998.
 
RESULTS OF OPERATIONS--YEAR ENDED JANUARY 31, 1997 COMPARED TO YEAR ENDED
  JANUARY 31, 1996
 
    The Company's strategy is to increase revenue and profitability through
growth in existing channels, through acquisitions, and through improvement in
efficiencies. In fiscal 1997 the Company was partially successful in
implementing this strategy. The Company merged with Satastar Corporate Services,
Inc., a videotape duplicator located in Chicago, expanded the Seattle operation
from a sales office to a full service duplication facility, and completed the
integration of IAAC (acquired January 31, 1996) into the Products Division by
consolidating the Division's operations in Seattle. In spite of these
accomplishments, the financial results for fiscal 1997 did not meet the
Company's expectations. Lower than expected sales, coupled with increased costs
associated with expanding the business, resulted in a decrease in net income
from the previous year. In response to these results, the Company implemented
cost containment measures during the year and expects these measures to have a
positive impact on next year's results.
 
    DISCUSSION OF COMBINED OPERATIONS BEFORE SELL-OFF OF PRODUCTS DIVISION
 
    The Company's net sales increased from $59,569,000 in fiscal 1996 to
$68,798,000 in fiscal 1997, a 15% increase, while gross margins remained at 32%.
Selling, general and administrative expenses for fiscal 1997 were up 21% over
the previous year and represented 25% of net sales, up one percentage point from
last year. Operating profit decreased 7% from last year to approximately
$4,712,000. Interest expense was down slightly from the previous year. The
Company's effective tax rate in fiscal 1997 was 42%. Net income decreased 10%
from $2,247,000 in fiscal 1996 to $2,015,000 in fiscal 1997.
 
    The net contribution each division made to these results is discussed below.
 
    COMMUNICATIONS DIVISION--CONTINUING OPERATIONS
 
    On June 28, 1996, the Company acquired Satastar by issuing 165,357 shares of
Vaughn Common Stock in exchange for all the outstanding capital stock of
Satastar. The business combination has been accounted for as a pooling of
interest, and, accordingly, the financial statements and analysis include the
combined results of operations from the date Satastar commenced operations.
 
    The Communications Division's sales of $55,040,000 in fiscal 1997 were a 5%
increase from the previous year's sales of $52,365,000. The slowdown in sales
growth in fiscal 1997 is attributed in part to a decrease in sales to the
Company's largest customers. While the Company added more new customers in
fiscal 1997 than in fiscal 1996, it was unable to offset the reduced sales to
its largest accounts. The Company believes that by refocusing its sales efforts,
the growth in sales will continue. There can be no assurance, however, that such
growth will be at or near historical levels, particularly since the growth of
the videotape duplication market may not be as great as historical levels.
 
    The gross profit margin increased slightly to 32.9% in fiscal 1997 from
32.7% in fiscal 1996. Although the selling price of videotape duplication
continues to decline, the Company expects to maintain its profit margins by
improving efficiencies, leveraging fixed costs with increased volume, and
continuing to utilize low-cost providers of raw materials.
 
    Selling, general and administrative expenses in fiscal 1997 increased 12.3%
from $12,232,000 in fiscal 1996 to $13,735,000 in fiscal 1997, and represented
25% of net sales in fiscal 1997 compared to 23.3% of net sales in fiscal 1996.
The increase in selling, general and administrative expenses can be attributed
in part to additional costs associated with the acquisition of Satastar, and
expenses incurred during the consolidation of the Company's existing facility in
Chicago with the facility used by Satastar.
 
                                       64
<PAGE>
    Net interest expense decreased 16% in fiscal 1997 due to lower levels of
borrowing.
 
    Pre-tax profit for the Communications Division was $3,314,000, a 11%
decrease from the previous year's pre-tax profit of $3,707,000. The decrease was
attributable primarily to the higher levels of operating expenses.
 
    The Company spent approximately $2,750,000 on equipment and facilities to
expand its production capacity. The investment was funded by long-term financing
and internally generated funds.
 
    PRODUCTS DIVISION--DISCOUNTED OPERATIONS
 
    The Products Division's sales of $13,758,000 in fiscal 1997 were up 91% from
the previous year. The increase was due entirely to the acquisition of IAAC on
January 31, 1996. The sales from the newly acquired product line offset a slight
decrease in sales of the pre-existing product line.
 
    The fiscal 1997 gross profit margin of 26% remained approximately the same
as the previous year. A slight decrease in raw material costs was offset by
higher labor costs. The higher labor costs were associated with operating two
facilities prior to consolidating operations in Seattle in September, 1996. The
Company expects that the combined operations will result in improved
efficiencies next year.
 
    Operating expenses for fiscal 1997 increased 86% to $3,239,000 due to the
acquisition of IAAC. As a percentage of sales, operating expenses decreased from
24.2% in fiscal 1996 to 23.5% in fiscal 1997.
 
    Interest expense increased from $98,000 in fiscal 1996 to $229,000 in fiscal
1997 due primarily to higher debt associated with the acquisition.
 
    Pre-tax income increased 100% in fiscal 1997, from $80,000 to $161,000.
 
    LIQUIDITY AND SOURCES OF CAPITAL
 
    Cash provided by operations and financing provided by banks and third
parties continue to be the Company's primary sources of funds to finance
operating needs and capital expenditures. In the first nine months of fiscal
1999, cash flow from operations of $7,126,000, along with borrowings from third
parties, was used to fund capital expenditures of approximately $4,870,000 and
to fund the $1,580,000 purchase price of Copywise.
 
    Based on past performance and current expectations, the Company believes
that working capital levels, coupled with its ability to borrow additional funds
under its $17,000,000 credit facility with a bank (of which approximately
$3,138,000 is available at October 31, 1998), are adequate to meet the operating
requirements of the Company for the next six months.
 
    Expenditures for new equipment are expected to be approximately $6,000,000
in fiscal 1999 and will be funded by leasing arrangements with third parties and
cash from operations. As part of the Company's strategic planning process, it
continues to explore alternative funding proposals.

                         REPORT OF INDEPENDENT AUDITORS
 
The Shareholders and Board of Directors
Vaughn Communications, Inc.
 
We have audited the accompanying consolidated balance sheets of Vaughn
Communications, Inc. and subsidiaries as of January 31, 1998 and 1997, and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the three years in the period ended January 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Vaughn
Communications, Inc. and subsidiaries at January 31, 1998 and 1997, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended January 31, 1998, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                                JANUARY 31, 1998
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS ACTIVITY
 
    Vaughn Communications, Inc. is one of the largest providers in the United
States of high volume videotape duplication and compact disc replication
services to corporations, publishers and educational companies located in the
United States. The Company operates videotape duplication centers throughout the
country in areas selected because of their proximity to large corporate bases.
In addition to video services, the Company has generated approximately 16%, 20%
and 12% of its net sales for the years ended January 31, 1998, 1997 and 1996,
respectively, from the manufacture and sale of gift products to retailers in
niche markets. Additional information on the Company's operations by segment is
included in Note 9 to the consolidated financial statements.
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and of its majority-owned subsidiaries after elimination of all significant
intercompany accounts and transactions.
 
INVENTORIES
 
    Inventories are valued at the lower of average cost (first-in, first-out
method) or market.
 
PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are stated on the basis of cost. Assets are
depreciated using the straight-line and declining balance methods over their
estimated useful lives which are as follows:
 
<TABLE>
<S>                                                              <C>
Buildings......................................................  40 years
Equipment......................................................  3-5 years
Leasehold improvements.........................................  5-10 years
</TABLE>
 
    The carrying value of property, plant and equipment is assessed annually
and/or when factors indicating an impairment are present.
 
INTANGIBLE ASSETS
 
    The intangible assets include the excess of purchase price over the fair
value of net assets of businesses acquired and are being amortized over periods
of 10 to 40 years using the straight-line method. The carrying value of
intangible assets is assessed annually and/or when factors indicating impairment
are present.
 
INCOME TAXES
 
    The Company accounts for income taxes utilizing the liability method.
Deferred taxes are recorded to reflect the tax consequences of differences
between tax and financial reporting basis of assets and liabilities.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
NET INCOME PER SHARE
 
    In fiscal 1998, the Company adopted Statement of Financial Accounting
Standard No. 128 (SFAS 128), "Earnings Per Share." SFAS 128 requires the
disclosure of basic and diluted earnings per share (EPS). Basic EPS is
calculated using income available to common shareholders divided by the weighted
average of common shares outstanding during the year. Diluted EPS is similar to
basic EPS except that the weighted average of common shares outstanding is
increased to include the number of additional shares that would have been
outstanding if the dilutive potential common shares, such as options, had been
issued. All prior year earnings per share have been restated in accordance with
the provisions of SFAS 128 (see Note 11).
 
STATEMENT OF CASH FLOWS
 
    For purposes of the statements of cash flows, the Company considers all
highly liquid investments with a maturity of three months or less when purchased
to be cash equivalents.
 
STOCK-BASED COMPENSATION
 
    The Company follows Accounting Principles Board Opinion No. 25, ACCOUNTING
FOR STOCK ISSUED TO EMPLOYEES, (APB 25) and related interpretations in
accounting for its employee stock options. Under APB 25, when the exercise price
of employee stock options equals the market price of the underlying stock on the
date of the grant, no compensation expense is recognized.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2. INVENTORIES

market price of the underlying stock on the date of grant, no compensation
expense is recognized.
 
    Pro forma information regarding net income and net income per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its employee stock options under the fair value method of that Statement.
The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted average
assumptions for years ended January 31, 1996, 1997 and 1998: risk-free interest
rates ranging from 5.26% to 7.5%; dividend yield of 0%; volatility factor of the
expected market price of the Company's common stock of .60; and a weighted
average expected life of the option of 5 years. The weighted average fair value
of options granted during the years ended January 31, 1998, 1997 and 1996 was
$3.87, $6.51 and $3.96 per share, respectively.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restriction and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable measure of
the fair value of its employee stock options.

8. RELATED PARTY TRANSACTION
 
    Pursuant to a Stock Put Redemption Agreement between the Company and its
Chief Executive Officer ("CEO") as amended June 24, 1992, the Company has agreed
to redeem shares of Common Stock having a value of up to $1,500,000 from the
CEO's estate, following his death or, unless the Board determines that such
redemption is not in the best interest of the Company, from the CEO upon any
entity acquiring beneficial ownership of in excess of 20% of the Company without
Board approval. The put options to require or request redemption by the Company
can be exercised any time up to one year after the date of the event giving rise
to the option. The per share redemption price, in the event of death, will be
the greater of the fair market value or book value of the Common Stock. The per
share redemption price in event of change in control will be the greater of fair
market value, the highest price paid by the new controlling shareholder, or a
multiple of ten times net pretax income per share. Any redemption from the CEO's
estate will be paid out of the proceeds of $1,500,000 of term life insurance
which the Company carries on the CEO's life.

10. ACQUISITIONS
 
    In July 1997, the Company acquired certain assets and assumed certain
liabilities of Certified Media Corporation ("CMC"), a compact disc replicator
located in Fremont, California. The initial purchase price was $5,500,000,
including $2,800,000 of cash, 171,210 shares of Vaughn Communications, Inc.
common stock valued at $1,200,000, and long-term debt to the sellers of
$1,500,000. The purchase price may be increased to a maximum of $7,500,000
depending upon CMC's attainment of specific financial objectives through January
31, 1999. Goodwill recorded in this transaction is being amortized over 15 years
using the straight-line method.
 
    In July 1997, the Company also acquired certain assets of Dub South, a
videotape duplicator located in Atlanta, Georgia. The noncontingent purchase
price included $750,000 of cash and the assumption of approximately $750,000 of
liabilities. The purchase price may be increased by an additional $1,200,000,
depending on the profit performance for the next five years. There was no
goodwill recorded on this transaction.
 
    Both acquisitions have been accounted for by the purchase method of
accounting, and the consolidated financial statements for the year ended January
31, 1998 reflect the purchase of the businesses, and include any results from
operations subsequent to the closing dates of the respective transactions.
 
    Satastar Corporate Services, Inc. ("Satastar," dba PVS Corporate Services),
a videotape duplicator located in Chicago, Illinois, was merged with the Company
in June 1996 by the issuance of 165,357 shares of common stock in exchange for
all of the outstanding capital stock of Satastar Corporate Services, Inc. The
business combination has been accounted for as a pooling of interests and,
accordingly, the consolidated financial statements of the Company include the
combined results of operations of the Company and Satastar for all years
presented.
 
    Included in results of operations for the year ended January 31, 1997 are

    Options to purchase 204,648 shares of common stock were not included in the
computation of diluted net income per share for fiscal 1998 because the options'
exercise price was greater than the average market price of the common shares.

13. SUBSEQUENT EVENT
 
    In February 1998, the Company completed the acquisition of the assets of
Copywise, Inc. ("Copywise"), a floppy disk replicator located in Fremont,
California. The acquisition will be accounted for by the purchase method of
accounting. Goodwill associated with the purchase will be amortized over 15
years. The noncontingent purchase price was approximately $1,670,000 of cash and
the assumption of approximately $667,000 of liabilities. The purchase price may
be increased by an additional $1,560,000 depending upon the attainment of
certain financial objectives by the acquired business through January 31, 2000.

operations of the Products Division. The Products Division's operations
consisted of the manufacture and sale of souvenirs, gifts, leather products and
soft goods. The net selling price was approximately $1,232,000, and resulted in

    The Company allocated interest expense to the Products Division based on the
ratio of net assets discontinued to the sum of the Company's consolidated total
net assets. The sale of the Products Division has been accounted for as a
discontinued operation and the consolidated statements of income for the years
ended January 31, 1998, 1997 and 1996, as well as corresponding amounts in Notes
7, 9 and 11, have been restated to give effect to such treatment.

    prior to the Effective Time shall no longer be outstanding and shall
    automatically be canceled and retired and shall cease to exist, and each
    holder of a certificate representing any such shares of Company Common Stock
    shall cease to have any rights with respect thereto, except the right to
    receive the Merger Consideration in accordance with Section 2.1(c) upon
    surrender of such certificate in accordance with Section 2.5, and except for
    those holders who validly exercise, preserve and protect their Dissenters'
    Rights whose entitlement to receive any form of
 
                                      A-2
<PAGE>
    consideration under this Agreement shall be governed by Section 302A.473 of
    the MBCA ("Section 302A.473").
 
    2.2  APPOINTMENT OF EXCHANGE AGENT.  Prior to the mailing of the Proxy
Statement, Sub shall appoint a bank or trust company designated by Sub and
reasonably satisfactory to the Company to act as exchange agent (the "Exchange
Agent") for the payment of the Merger Consideration.
 
    2.3  PAYMENT OF MERGER CONSIDERATION.
 
        (a)  PERSONS ENTITLED TO MERGER CONSIDERATION.  The manner in which each
    share of Company Common Stock (other than shares of Company Common Stock to
    be canceled as set forth in Section 2.1(b)) shall be converted as of the
    Effective Time into the right to receive the Merger Consideration shall be
    as set forth in this Section 2.3. All references to "outstanding shares of
    Company Common Stock" in this Section 2.3 shall mean all shares of Company
    Common Stock outstanding immediately prior to the Effective Time. Each
    Person who is a record holder of shares of Company Common Stock as of the
    record date for the meeting of the Company's shareholders called to approve
    the Merger and this Agreement, and who has not validly exercised, preserved
    and protected Dissenters' Rights and remains a record holder of such stock
    until the Effective Time, will be entitled, with respect to all of his
    shares, to receive the Merger Consideration.
 
        (b)  DISSENTERS' RIGHTS.  Any holder of outstanding shares of Company
    Common Stock (other than shares referred to in Section 2.1(b)) who has not
    voted for the Merger and who has properly exercised, preserved and protected
    Dissenters' Rights shall be entitled to receive only such consideration as
    determined in accordance with Section 302A.473; PROVIDED, HOWEVER, that any
    holder of outstanding shares of Company Common Stock (other than shares
    referred to in Section 2.1(b)) who has not voted for the Merger, but has
    failed to properly exercise, preserve and protect Dissenters' Rights, shall
    be entitled to receive the Merger Consideration in accordance with the terms
    and conditions of this Agreement in lieu of the rights of a dissenting
    shareholder under Section 302A.473.
 
    2.4  STOCK PLANS.  Prior to the mailing of the Proxy Statement, the Board of
Directors of the Company (or, if appropriate, any committee administering the
Stock Plans (as defined below)) shall adopt such resolutions or take such other
actions as may be required to effect the following:
 
        (a)  CANCELLATION OF COMPANY STOCK OPTIONS.  Other than as expressly set
    forth in the Willette Option Termination Agreement, the Company shall adjust
    the terms of all outstanding options to purchase shares of Company Common
    Stock ("Company Stock Options") granted under the Company's 1983 Incentive
    Stock Option Plan, the Company's 1985 Stock Option Plan, the Company's 1988
    Stock Option Plan, the Company's 1990 Discounted Stock Option Plan, the
    Company's 1990 Non-Employee Directors Stock Option Plan, the Company's 1990
    Company Wide Stock Option Plan, the Company's 1995 Stock Option Plan, the
    Company's 1995 Non-Employee Directors Stock Option Plan or the Company's
    1998 Stock Option Plan and any other plan or arrangement providing for the
    issuance or grant of any interest in respect of capital stock of the Company
    or any former Subsidiary (collectively, the "Option Plans") to provide that,
    at the Effective Time, each Company Stock Option outstanding immediately
    prior to the Effective Time, whether or not then vested or exercisable,
    shall be canceled and thereafter the former holder thereof shall be entitled
    by having held such Company Stock Option only to a payment from the
    Surviving Corporation (subject to any applicable withholding taxes, as the
    case may be) equal to the product of (i) the total number of shares of
    Company Common Stock subject to such Company Stock Option and (ii) the
    excess of $10.00 over the exercise price per share of Company Common Stock
    subject to such Company Stock Option, payable in cash immediately following
    the Effective Time.
 
        (b)  TERMINATION OF STOCK PLANS.  Except as otherwise agreed to in
    writing by Sub, the Option Plans and any other plan, program or arrangement
    providing for the issuance or grant of any interest in respect of the
    capital stock of the Company or any former Subsidiary (collectively, the
    "Stock
 
                                      A-3
<PAGE>
    Plans") shall terminate as of the Effective Time, and the Company shall
    ensure that following the Effective Time no holder of a Company Stock Option
    nor any participant in any of the Stock Plans shall have any right
    thereunder to acquire any equity securities of the Company or the Surviving
    Corporation.
 
    2.5  EXCHANGE OF CERTIFICATES.
 
        (a)  DEPOSIT CASH WITH EXCHANGE AGENT.  As soon as reasonably
    practicable as of or after the Effective Time, Sub shall deposit with the
    Exchange Agent, for the benefit of the holders of shares of Company Common
    Stock, for exchange in accordance with this Article 2, the Merger
    Consideration.
 
        (b)  EXCHANGE PROCEDURES.  As soon as practicable after the Effective
    Time, the Exchange Agent shall mail to each holder of an outstanding
    certificate or certificates which prior thereto represented shares of
    Company Common Stock (other than certificates held of record or beneficially
    by the Company or Sub and other than certificates held by a holder that has
    properly exercised, preserved and protected Dissenters' Rights) (i) a letter
    of transmittal (which shall specify that delivery shall be effected, and
    risk of loss and title to such certificate shall pass, only upon delivery of
    such certificates to such Exchange Agent), and (ii) instructions for use in
    effecting the surrender of the certificates for the Merger Consideration.
    Upon proper surrender to the Exchange Agent of such certificates for
    cancellation, the holder of such certificates shall after the Effective Time
    be entitled only to the amount of cash into which the aggregate number of
    shares of Company Common Stock previously represented by such certificate or
    certificates surrendered shall have been converted pursuant to this
    Agreement. The Exchange Agent shall accept such certificates upon compliance
    with such reasonable terms and conditions as the Exchange Agent may impose
    to effect an orderly exchange thereof in accordance with normal exchange
    practices. After the Effective Time, there shall be no further transfer on
    the records of the Company or its transfer agent of certificates
    representing shares of Company Common Stock and if such certificates are
    presented to the Company for transfer, they shall be canceled against
    delivery of cash as hereinabove provided. If cash is to be remitted to a
    Person other than that in which the certificate for Company Common Stock
    surrendered for exchange is registered, it shall be a condition of such
    exchange that the certificate so surrendered shall be properly endorsed,
    with signature guaranteed, or otherwise in proper form for transfer and that
    the Person requesting such exchange shall establish to the satisfaction of
    the Surviving Corporation or its transfer agent that any transfer or other
    taxes required by reason of payment of Merger Consideration to a Person
    other than that of the registered holder of the certificate surrendered has
    been paid or is not applicable. Until surrendered as contemplated by this
    Section 2.5(b), each certificate for shares of Company Common Stock shall be
    deemed at any time after the Effective Time to represent only the right to
    receive upon such surrender the Merger Consideration. No interest will be
    paid or will accrue on any cash payable as Merger Consideration.
 
        (c)  LOST CERTIFICATES.  In the event that a certificate for shares of
    Company Common Stock shall have been lost, stolen or destroyed, upon the
    making of an affidavit of that fact by the holder claiming such certificate
    to have been lost, stolen or destroyed, the amount to which such holder
    would have been entitled under Section 2.5(b) but for failure to deliver
    such certificate to the Exchange Agent shall nevertheless be paid to such
    holder, provided that the Surviving Corporation may, in its sole discretion
    and as a condition precedent to such payment, require such holder to give
    the Surviving Corporation a bond in such sum as it may reasonably direct as
    indemnity against any claim that may be had against the Surviving
    Corporation with respect to the certificate alleged to have been lost,
    stolen or destroyed.
 
        (d)  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All cash paid
    upon the surrender for exchange of certificates representing shares of
    Company Common Stock in accordance with the terms of this Article 2
    (including any cash paid pursuant to the valid exercise of Dissenters'
    Rights)
 
                                      A-4
<PAGE>
    shall be deemed to have been issued (and paid) in full satisfaction of all
    rights pertaining to the shares of Company Common Stock theretofore
    represented by such certificates.
 
        (e)  TERMINATION OF EXCHANGE FUND.  Any portion of the Merger
    Consideration deposited with the Exchange Agent pursuant to this Section 2.5
    (the "Exchange Fund") which remains undistributed to the holders of the
    certificates representing shares of Company Common Stock for six months
    after the Effective Time shall be delivered to the Surviving Corporation,
    upon demand, and any holders of shares of Company Common Stock who have not
    theretofore complied with this Article 2 shall thereafter look only to the
    Surviving Corporation and only as general creditors thereof for payment of
    their claim for cash.
 
        (f)  NO LIABILITY.  To the fullest extent permitted by Law, none of Sub,
    the Company or the Exchange Agent shall be liable to any Person in respect
    of cash from the Exchange Fund delivered to a public official pursuant to
    any applicable abandoned property, escheat or similar law. If any
    certificates representing shares of Company Common Stock shall not have been
    surrendered prior to five years after the Effective Time (or immediately
    prior to such earlier date on which any cash in respect of such certificate
    would otherwise escheat to or become the property of any Governmental
    Entity), any such cash in respect of such certificate shall, to the extent
    permitted by applicable law, become the property of the Surviving
    Corporation, free and clear of all claims or interest of any Person
    previously entitled thereto.
 
        (g)  INVESTMENT OF EXCHANGE FUND.  The Exchange Agent shall invest the
    cash included in the Exchange Fund, as directed by the Surviving
    Corporation, on a daily basis. Any interest and other income resulting from
    such investments shall be paid to the Surviving Corporation.
 
                                   ARTICLE 3
 
                         REPRESENTATIONS AND WARRANTIES

    in good standing in each jurisdiction in which the nature of its business or
    the ownership or leasing of its properties and assets makes such
    qualification or licensing necessary, other than in such jurisdictions where

    aggregate) would not have a Material Adverse Effect with respect to the
    Company. Attached as Section 3.1(a) of the Company Disclosure Schedule are
    complete and correct copies of the Articles and Bylaws of the Company.
 
        (b)  SUBSIDIARIES.  The Company has no Subsidiaries. The Company does

    Stock Options granted under the Option Plans and immediately exercisable.
    Except as set forth above, no shares of capital stock or other equity

    Except as set forth above, there are no outstanding securities, options,
    warrants, preemptive rights, calls, rights, commitments, agreements,
    arrangements or undertakings of any kind to which the Company is a party or

    the Knowledge of the Company, there are no irrevocable proxies with respect
    to shares of capital stock of the Company. Other than as set forth in
    Section 3.1(c) of the Company Disclosure Schedule, there are no agreements
    or arrangements pursuant to which the Company is or could be required to

    Securities Act of 1933, as amended (the "Securities Act").
 
        (d)  AUTHORITY; NONCONTRAVENTION.  The Company has the requisite
    corporate power and authority to enter into this Agreement and, subject to
    the Company Shareholder Approval with respect to the consummation of the
    Merger, to consummate the transactions contemplated hereby and to perform

    the Company and the consummation by the Company of the transactions
    contemplated hereby have been duly and validly authorized by all necessary
    corporate action on the part of the Company and no other corporate

    Agreement or consummate the contemplated transactions, subject, in the case
    of the Merger, to the Company Shareholder Approval. This Agreement has been
    duly executed and delivered by the Company and constitutes a valid and
    binding obligation of the Company, enforceable against the Company in
    accordance with its terms. Except as disclosed in Section 3.1(d) of the
    Company Disclosure Schedule, the execution and delivery of this Agreement
    does not, and the consummation of the transactions contemplated hereby and
    compliance with the provisions hereof 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 give rise to a right of termination, cancellation
    or 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 the Company under, (i) the Articles or
    bylaws, as they may be amended and restated (the "Bylaws"), of the Company,
    (ii) any Contract or Permit applicable to the Company or its properties or
    assets or (iii) subject to the governmental filings and other matters
    referred to in the following sentence, any Order, Laws, or arbitration award
    applicable to the Company or its properties or assets; other than, in the
    case of clauses (ii) and (iii), any such conflicts, breaches, violations,
    defaults, rights, losses or Liens that individually or in the aggregate
    could not have a Material Adverse Effect with respect to the Company or
    could not prevent, hinder or materially delay the ability of the Company to
    consummate the transactions contemplated by this Agreement. No consent,
    approval, Order or authorization of, or registration, declaration or filing
    with, or notice to, any Governmental Entity, is required by or with respect

<PAGE>
    Agreement by the Company or the consummation by the Company of the
    transactions contemplated hereby, except for (i) the filing of a premerger
    notification and report form by the Company under the Hart-Scott-Rodino
    Antitrust Improvements Act of 1976, as amended (the "HSR Act"), (ii) the
    filing with the United States Securities and Exchange Commission (the "SEC")
    of (y) a proxy statement relating to the Company Shareholder Approval (such
    proxy statement as amended or supplemented from time to time, the "Proxy
    Statement"), and (z) such reports under the Securities Exchange Act of 1934
    (the "Exchange Act") as may be required in connection with this Agreement
    and the transactions contemplated by this Agreement, (iii) the filing of the
    Certificate of Merger with the Secretary of State of the State of Minnesota,
    and appropriate documents with the relevant authorities of other states in
    which the Company is qualified to do business and (iv) such other consents,
    approvals, Orders, authorizations, registrations, declarations, filings or
    notices as are set forth in Section 3.1(d) of the Company Disclosure
    Schedule. The Board of Directors (at a meeting duly called and held at which
    a quorum was present), based upon the unanimous recommendation of a
    committee (the "Special Committee") comprised solely of all of the Company's
    disinterested directors (as such term is defined in Section 302A.673 of the
    MBCA), has unanimously determined that the Merger is advisable and in the
    best interests of the Company and has unanimously resolved to recommend
    approval of the Merger and adoption of this Agreement by the holders of the
    Company Common Stock.
 
        (e)  SEC DOCUMENTS; UNDISCLOSED LIABILITIES; FINANCIAL STATEMENTS.
 
           (i) The Company has filed all required reports, schedules, forms,
       statements and other documents with the SEC since February 1, 1995
       (collectively, and in each case including all exhibits and schedules
       thereto and documents incorporated by reference therein, the "SEC
       Documents"). As of their respective dates, the SEC Documents complied in
       all material respects with the requirements of the Securities Act or the
       Exchange Act, as the case may be, and the rules and regulations of the
       SEC promulgated thereunder applicable to such SEC Documents, and none of
       the SEC Documents (including any and all financial statements included
       therein) as of such dates contained any untrue statement of a material
       fact or omitted to state a material fact required to be stated therein or
       necessary in order to make the statements therein, in light of the
       circumstances under which they were made, not misleading. The
       consolidated financial statements of the Company included in the SEC
       Documents (the "SEC Financial Statements") comply as to form in all
       material respects with applicable accounting requirements and the
       published rules and regulations of the SEC with respect thereto, have
       been prepared in accordance with GAAP (except, in the case of unaudited
       consolidated quarterly statements, as permitted by Form 10-Q of the SEC)
       applied on a consistent basis during the periods involved (except as may
       be indicated in the notes thereto) and fairly present the consolidated
       financial position of the Company and its former Subsidiaries as of the
       dates thereof and the consolidated results of their operations and cash
       flows for the periods then ended (subject, in the case of unaudited
       quarterly statements, to normal year-end audit adjustments).
 
           (ii) The Company has furnished Sub with the unaudited consolidated
       balance sheet of the Company as of November 30, 1998 (after giving effect
       to the consummation of the disposition of the Products Division of the
       Company) (the "Unaudited Financial Statement"). The Unaudited Financial
       Statement fairly presents the consolidated financial position of the
       Company as of November 30, 1998 (after giving effect to the consummation
       of the disposition of the Products Division), and has been prepared in
       conformity with GAAP, except as otherwise specifically noted in the notes
       thereto.
 
           (iii) Except for Liabilities which are accrued or reserved against in
       the SEC Financial Statements (or reflected in the notes thereto) or which
       were incurred after the date of the most recent SEC Financial Statements
       in the ordinary course of business and consistent with past practices or
       which are set forth in Section 3.1(e) of the Company Disclosure Schedule,
       the Company does not have any material Liabilities (whether absolute,
       accrued, contingent or otherwise).
 
                                      A-7
<PAGE>
        (f)  INFORMATION SUPPLIED.  None of the information supplied or to be
    supplied by the Company for inclusion or incorporation by reference in the
    Proxy Statement will, at the date it is first mailed to the Company's
    shareholders or at the time of the Special Meeting, contain any untrue
    statement of a material fact or omit to state any material fact required to
    be stated therein or necessary in order to make the statements therein, in
    light of the circumstances under which they are made, not misleading. The
    Proxy Statement will comply as to form in all material respects with the
    requirements of the Exchange Act and the rules and regulations promulgated
    thereunder, except that no representation is made by the Company with
    respect to statements made or incorporated by reference therein based on
    information supplied by Sub for inclusion or incorporation by reference
    therein.
 
        (g)  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
    Section 3.1(g) of the Company Disclosure Schedule, since February 1, 1995,
    the Company has conducted its business only in the ordinary course
    consistent with past practice, and since December 31, 1997, there is not and
    has not been: (i) any Material Adverse Change with respect to the Company;
    (ii) any condition, event or occurrence which, individually or in the
    aggregate, could reasonably be expected to have a Material Adverse Effect or
    give rise to a Material Adverse Change with respect to the Company; (iii)
    any event which, if it had taken place following the execution of this
    Agreement, would not have been permitted by Section 4.1 without the prior
    consent of Sub; or (iv) any condition, event or occurrence which would
    prevent, hinder or materially delay the ability of the Company to consummate
    the transactions contemplated by this Agreement.
 
        (h)  LITIGATION; LABOR MATTERS; COMPLIANCE WITH LAWS.
 
           (i) Except as set forth in Section 3.1(h) of the Company Disclosure
       Schedule, there is no suit, action or proceeding or investigation pending
       or, to the Knowledge of the Company, threatened against or affecting the
       Company and no basis for any such suit, action, proceeding or
       investigation that, individually or in the aggregate, could reasonably be
       expected to have a Material Adverse Effect with respect to the Company or
       prevent, hinder or materially delay the ability of the Company to
       consummate the transactions contemplated by this Agreement, nor is there
       any Order of any Governmental Entity or arbitrator outstanding against
       the Company having, or which, insofar as reasonably could be foreseen by
       the Company, in the future could have, any such effect.
 
           (ii) The Company is not a party to, or bound by, any collective
       bargaining agreement, Contract or other agreement or understanding with a
       labor union or labor organization, and it is not the subject of any
       proceeding asserting that it has committed an unfair labor practice or
       seeking to compel it to bargain with any labor organization as to wages
       or conditions of employment, nor is there any strike, work stoppage or
       other labor dispute involving it pending or, to its Knowledge,
       threatened, any of which could have a Material Adverse Effect with
       respect to the Company.
 
           (iii) The conduct of the Business substantially complies with all
       statutes, Laws, regulations, ordinances, rules, judgments, Orders,
       decrees or arbitration awards applicable thereto, except for violations
       or failures so to comply, if any, that, individually or in the aggregate,
       could not reasonably be expected to have a Material Adverse Effect with
       respect to the Company.
 
        (i)  EMPLOYEE MATTERS.  The Company has delivered to Sub full and
    complete copies or descriptions of and Section 3.1(i) of the Company
    Disclosure Schedule sets forth a list of each material employment,
    severance, bonus, profit sharing, compensation, termination, stock option,
    stock appreciation right, restricted stock, phantom stock, performance unit,
    pension, retirement, deferred compensation, welfare or other employee
    benefit agreement, trust fund or other arrangement and any union, guild or
    collective bargaining agreement maintained or contributed to or required to
    be contributed to by the Company or any of its ERISA Affiliates, for the
    benefit or welfare of any director, officer, employee or former employee of
    the Company or any of its ERISA Affiliates (such plans and
 
                                      A-8
<PAGE>
    arrangements being collectively the "Company Benefit Plans"), whether or not
    subject to the Employee Retirement Income Security Act of 1974, as amended
    ("ERISA"). Each of the Company Benefit Plans is in material compliance with
    all applicable Laws including ERISA and the Code and all contributions have
    been made on a timely basis. The Liabilities accrued under each Company
    Benefit Plan are reflected on the latest balance sheet of the Company
    included in the SEC Documents in accordance with GAAP applied on a
    consistent basis. The Company has no Company Benefit Plan that is a
    "multiemployer plan" as such term is defined in Section 3(37) of ERISA (a
    "Multiemployer Plan"). The Company has no Company Benefit Plan that is
    subject to Title IV of ERISA. There are no pending, threatened, or
    anticipated claims (other than routine claims for benefits or immaterial
    claims) by, on behalf of or against any of the Company Benefit Plans or any
    trusts related thereto. Each Company Benefit Plan intended to qualify under
    Section 401(a) of the Code has at all times since its adoption been so
    qualified, and each trust which forms a part of any such plan has at all
    times since its adoption been Tax-exempt under Section 501(a) of the Code.
    Neither the Company, any former Subsidiary nor any ERISA Affiliate has
    incurred any liability for any Tax imposed under Section 4971 through 4980B
    of the Code or civil liability under Section 502(i) or (l) of ERISA. No
    benefit under any Company Benefit Plan, including, without limitation, any
    severance or parachute payment plan or agreement, will be established or
    become accelerated, vested or payable by reason of any transaction
    contemplated under this Agreement, other than as specifically set forth in
    Section 2.4 hereof or in the employment agreements with Donald J. Drapeau
    and M. Charles Reinhart. No Company Benefit Plan provides health or death
    benefit coverage beyond the termination of an employee's employment, except
    as required by Part 6 of Subtitle B of Title I of ERISA or Section 4980B of
    the Code or any State Laws requiring continuation of benefits coverage
    following termination of employment. "ERISA Affiliate" means, with respect
    to any Person, any trade or business, whether or not incorporated, that
    together with such Person would be deemed a "single employer" within the
    meaning of Section 4001(a)(15) of ERISA.

    former Subsidiaries is or has been a member of any consolidated, combined,
    unitary or aggregate group for Tax purposes except such a group consisting

<PAGE>
    Agreement and compliance 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) under, or give rise to a right of
    termination, cancellation or acceleration of or "put" right with respect to
    any obligation or to any loss of a material benefit under, or result in the
    creation of any Lien upon any of the properties or assets of Sub under, (i)
    the Articles of Incorporation or bylaws of Sub, (ii) any Contract or Permit
    applicable to Sub or its properties or assets or (iii) subject to the
    governmental filings and other matters referred to in the following
    sentence, any Order, Laws or arbitration award applicable to Sub or its
    respective properties or assets; other than, in the case of clauses (ii) and
    (iii), any such conflicts, breaches, violations, defaults, rights, losses or
    Liens that individually or in the aggregate could not have a Material
    Adverse Effect with respect to Sub or could not prevent, hinder or
    materially delay the ability of Sub to consummate the transactions
    contemplated by this Agreement. No consent, approval, Order or authorization
    of, or registration, declaration or filing with, or notice to, any
    Governmental Entity is required by or with respect to Sub in connection with

    contemplated hereby, (iii) the filing of the Certificate of Merger with the
    Secretary of State of the State of Minnesota, and (iv) such other consents,
    approvals, Orders, authorizations, registrations, declarations, filings or
    notices as may be required under the "takeover" or "blue sky" laws of
    various states.
 
        (d)  INFORMATION SUPPLIED.  None of the information supplied or to be
    supplied by Sub for inclusion or incorporation by reference in the Proxy
    Statement will, at the date the Proxy Statement is first mailed to the
    Company's shareholders or at the time of the Special Meeting, contain any
    untrue statement of a material fact or omit to state any material fact
    required to be stated therein or necessary in order to make the statements
    therein, in light of the circumstances under which they are made, not
    misleading.
 
        (e)  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Sub has conducted its
    business only in the ordinary course consistent with past practice, and
    there is not and has not been (i) any Material Adverse Change with respect
    to Sub; (ii) any condition, event or occurrence which, individually or in
    the aggregate, could reasonably be expected to have a Material Adverse
    Effect or give rise to a Material Adverse Change with respect to Sub; or
    (iii) any condition, event or occurrence which could reasonably be expected
    to prevent, hinder or materially delay the ability of Sub to consummate the
    transactions contemplated by this Agreement.
 
        (f)  BROKERS.  No broker, investment banker, financial advisor or other
    Person is entitled to or may be paid any broker's, finder's, financial
    advisor's or other similar fee or commission in connection with the

        clause (ii) below, all of the financing required in order to consummate
        the transactions contemplated by this Agreement and to fund what Sub
        reasonably believes to be the working capital needs of the Company
        following the Closing. The financing to be provided pursuant to the
        foregoing arrangements is hereinafter referred to as the "Financing." As
        of the date hereof, the Bank Commitment Letters relating to the
        Financing have not been withdrawn and are in full force and effect.

    shareholder" of the Company as defined in Section 302A.011, Subd. 49(a) of
    the MBCA immediately prior to Sub's execution and delivery of this
    Agreement.
 
        (i)  NO OTHER REPRESENTATIONS AND WARRANTIES.  Sub represents and
    warrants that it is not relying upon any representations and warranties of
    the Company that are not contained in this Agreement or in the documents and
    instruments delivered with this Agreement or in the Company Disclosure
    Schedule and agrees that there shall not be deemed to be any other express
    or implied representations or warranties made by or on behalf of the Company
    in connection with the Merger or the other transactions contemplated by this

    connection with the Merger) to a third party who has made an unsolicited
    Transaction Proposal, (ii) engaging in discussions or negotiations with a
    third party who has made an unsolicited Transaction Proposal, (iii)
    following receipt of an unsolicited Transaction Proposal, taking and
    disclosing to its shareholders a position contemplated by Rules 14d-9 and
    14e-2 under the Exchange Act (provided no such position shall constitute a
    recommendation of such transaction if it does not constitute a Superior
    Acquisition Proposal) or otherwise complying with its duties of disclosure
    under applicable state law, and/or (iv) following receipt of an unsolicited
    Transaction Proposal, failing to make or withdrawing or modifying its
    recommendation referred to in Section 3.1(p), but in each case referred to
    in the foregoing clauses (i) through (iv) only if and to the extent that the
    Board of Directors of the Company shall have concluded in good faith, after
    consulting with financial advisors and considering the advice of outside
    counsel, that (1) such action is required by the Board of Directors of the
    Company in the exercise of its fiduciary duties to the shareholders of the
    Company and (2) such action is reasonably likely to be subject to completion
    and would, if consummated, result in a Superior Acquisition Proposal;
    PROVIDED, FURTHER, that the Board of Directors of the Company shall not take
    any of the foregoing actions referred to in clauses (i) through (iv) until
    after giving at least one Business Day's advance written notice to Sub with
    respect to the actions specified in the foregoing clauses

    (i) through (iv) that it shall take. In addition, if the Board of Directors
    of the Company receives a Transaction Proposal, then the Company shall
    promptly inform Sub in writing of the material terms of such proposal and
    the identity of the Person making it. As of the date hereof, the Company
    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. Without limiting the foregoing, it is
    understood that any violation of the restrictions set forth in this Section
    by any director or executive officer of the Company or by any investment
    banker, financial adviser, attorney, accountant, or other representative of
    the Company shall be deemed to be a breach of this Section by the Company.

    and whether or not it involves the Person making the Transaction Proposal
    referred to in Section 5.8(b)(ii)(1) above) shall have been consummated
    within 12 months following the termination of this Agreement, the Company
    shall pay to Sub, within twenty (20) Business Days following such
    occurrence, a fee of $1.9 million together with reimbursement of all
    reasonable out-of-pocket costs, fees and expenses, including, without
    limitation, the reasonable fees and disbursements of banks, investment
    banks, accountants or legal counsel and the expenses of any litigation
    incurred in connection with collecting the fees and other amounts provided
    for in this Section 5.8(b) up to a maximum amount of $900,000 in the
    aggregate for all such costs, fees and expenses; provided, however, such fee

    employees of the Surviving Corporation who were eligible to actively
    participate in the Savings Plan as of the date of its termination. Such

    any time for any reason, or (ii) terminating or modifying to any extent or
    in any respect any employee benefit plan, program or arrangement that the

    administrator of (or under) each of the Option Plans, and/or shall take such
    other steps as may be necessary or appropriate, to amend the Option Plans
    and adjust the Company Stock Options so that the holders of such Company
    Stock Options (the "Optionees"), upon consummation of the Merger, shall only
    be entitled, with respect to each applicable Company Stock Option, to the
    difference between (x) $10.00 MINUS (y) the applicable exercise price. In
    addition, the Company and the Board of Directors shall cause each Optionee
    (other than the Optionee who is a party to the Willette Option Termination
    Agreement) to execute a written consent, which consent shall authorize the
    cancellation of each Company Stock Option in exchange for an amount in cash
    equal to the amount described herein, and shall waive all of such Optionee's
    rights under the Option Plans and any related agreements, including but not
    limited to the right to receive capital stock of the Company upon exercise

    herein contemplated or perform its obligations hereunder), and Sub shall
    have received a certificate signed on behalf of the Company by the Chief
    Executive Officer and the Chief Financial Officer of the Company to such

    substance reasonably satisfactory to it, that such Permits and Orders of
    Governmental Entities and other Persons as are necessary in connection with
    the transactions contemplated hereby have been obtained, except such Permits
    and Orders which are not, individually or in the aggregate, material to Sub
    or the Company or the failure of which to have been received would not

    by any other Person, that has a reasonable likelihood of success before any

    materially or otherwise directly or indirectly to restrain or prohibit the
    consummation of the Merger or seeking to obtain material damages or
    otherwise directly or indirectly relating to the

    7.1  TERMINATION.  This Agreement may be terminated and abandoned at any
time prior to the Effective Time of the Merger, whether before or after approval
of the Merger by the shareholders of the Company, applicable by written notice
to the other party:
 
        (a) by mutual written consent of Sub and the Company; or
 
        (b) by either Sub or the Company, if any Governmental Entity shall have
    issued an Order or taken any other action permanently enjoining, restraining
    or otherwise prohibiting the Merger and such Order or other action shall
    have become final and nonappealable; or
 
        (c) by either Sub or the Company, if the Merger shall not have been
    consummated on or before March 31, 1999 (other than due to the failure of
    the party seeking to terminate this Agreement to perform its obligations
    under this Agreement required to be performed at or prior to the Effective
    Time); or
 
        (d) by either Sub or the Company, if any required approval of the
    shareholders of the Company shall not have been obtained by reason of the
    failure to obtain the required vote upon a vote held at a duly held meeting
    of shareholders or at any adjournment thereof; or
 
        (e) by the Company, if at any time prior to the Effective Time, in the
    event that a Person has made a Transaction Proposal that the Board of
    Directors of the Company determines, in good faith, and after consultation
    with and advice from its financial advisors, is reasonably likely to be
    subject to completion and would, if consummated, result in a transaction
    more favorable, from a financial point of view, to the Company's
    shareholders than the transactions contemplated by this Agreement and the
    Merger (a "Superior Acquisition Proposal"); or
 
        (f) by Sub, if (i) the Board of Directors of the Company shall have
    withdrawn or modified or amended, in a manner adverse to Sub, either its
    approval or recommendation of this Agreement and the Merger or its
    recommendation that the Company's shareholders adopt and approve the
    transactions contemplated by this Agreement and the Merger, (ii) the Board
    of Directors of the Company shall have approved, recommended or endorsed any
    Superior Acquisition Proposal, or (iii) the Company has failed to duly call
    the Special Meeting to approve the Merger; or
 
        (g) by Sub, if the Company fails to perform any of its material
    obligations under this Agreement or has breached any material
    representation, warranty, or covenant contained herein when made or at any
    time prior to the Closing in any material respect, and after having been
    notified of such breach, the breach continues for thirty (30) days without
    cure after such notice; or
 
                                      A-26
<PAGE>
        (h) by the Company, if Sub fails to perform any of its respective
    material obligations under this Agreement or has breached any material
    representation, warranty or covenant contained herein when made or at any
    time prior to the Closing in any material respect, and after having been
    notified of such breach, the breach continues for thirty (30) days without
    cure after such notice.
 
        (i) by the Company, if Sub delivers the written notice to the Company
    contemplated by Section 5.2(c) with respect to either or both of the Bank
    Commitment Letters and, within 5 Business Days following the delivery of
    such written notice, Sub has not delivered to the Company either (i) a
    substitute commitment letter or letters on substantially the same terms and
    conditions as the applicable Bank Commitment Letter or Bank Commitment
    Letters which are the subject of the written notice contemplated by Section
    5.2(c) or (ii) a written notice setting forth a waiver by Sub of the
    condition set forth in Section 6.2(m) with respect to that portion of the
    Financing to be provided under the relevant Bank Commitment Letter or Bank
    Commitment Letters, as the case may be.
 
    7.2  EFFECT OF TERMINATION.  In the event of termination of this Agreement
by either the Company or Sub as provided in Section 7.1, this Agreement shall
forthwith become void and have no effect, without any Liability or obligation on
the part of Sub or the Company, other than pursuant to the provisions of Section
5.5 and this Section 7.2 and provided, further, that the Confidentiality
Agreement shall survive any such termination. Nothing contained in this Section
shall, however, relieve any party for any breach of the representations,
warranties, covenants or agreements set forth in this Agreement prior to any
such termination.
 
    7.3  AMENDMENT.  This Agreement may be amended by the parties at any time
before or after required approval of the Merger by the shareholders of the
Company; provided, however, that after such approval, there shall be made no
amendment that by Law requires further approval by such shareholders. This
Agreement may not be amended except by an instrument in writing signed on behalf
of each of the parties.
 
    7.4  EXTENSION; WAIVER.  At any time prior to the Effective Time, the
parties may (a) extend the time for the performance of any of the obligations or
other acts of the other parties, (b) waive any inaccuracies in the
representations and warranties contained in this Agreement or in any document
delivered pursuant to this Agreement or (c) subject to the proviso of Section
7.3, waive compliance with any of the agreements or conditions contained in this
Agreement. Any agreement on the part of a party to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on behalf of
such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of such
rights.

                                   ARTICLE I
                                  STOCKHOLDERS
 
    SECTION 1.  ANNUAL MEETING.  The annual meeting of the stockholders of the
Corporation shall be held on such date, at such time and at such place within or
without the State of Minnesota as may be designated by the Board of Directors,
for the purpose of electing Directors and for the transaction of such other
business as may be properly brought before the meeting.
 
    SECTION 2.  SPECIAL MEETINGS.  Except as otherwise provided in the
Certificate of Incorporation, a special meeting of the stockholders of the
Corporation may be called at any time by the Board of Directors. Any special
meeting of the stockholders shall be held on such date, at such time and at such
place within or without the State of Minnesota as the Board of Directors or the
officer calling the meeting may designate. At a special meeting of the
stockholders, no business shall be transacted and no corporate action shall be
taken other than that stated in the notice of the meeting unless all of the
stockholders are present in person or by proxy, in which case any and all
business may be transacted at the meeting even though the meeting is held
without notice.
 
    SECTION 3.  NOTICE OF MEETINGS.  Except as otherwise provided in these
By-Laws or by law, a written notice of each meeting of the stockholders shall be
given not less than ten (10) nor more than sixty (60) days before the date of
the meeting to each stockholder of the Corporation entitled to vote at such
meeting at his or her address as it appears on the records of the Corporation.
The notice shall state the place, date and hour of the meeting and, in the case
of a special meeting, the purpose or purposes for which the meeting is called.
 
    SECTION 4.  QUORUM.  At any meeting of the stockholders, the holders of a
majority in number of the total outstanding shares of stock of the Corporation
entitled to vote at such meeting, present in person or represented by proxy,
shall constitute a quorum of the stockholders for all purposes, unless the
representation of a larger number of shares shall be required by law, by the
Certificate of Incorporation or by these By-Laws, in which case the
representation of the number of shares so required shall constitute a quorum;
provided that at any meeting of the stockholders at which the holders of any
class of stock of the Corporation shall be entitled to vote separately as a
class, the holders of a majority in number of the total outstanding shares of
such class, present in person or represented by proxy, shall constitute a quorum
for purposes of such class vote unless the representation of a larger number of
shares of such class shall be required by law, by the Certificate of
Incorporation or by these By-Laws.
 
    SECTION 5.  ADJOURNED MEETINGS.  Whether or not a quorum shall be present in
person or represented at any meeting of the stockholders, the holders of a
majority in number of the shares of stock of the Corporation present in person
or represented by proxy and entitled to vote at such meeting may adjourn from
time to time; PROVIDED, HOWEVER, that if the holders of any class of stock of
the Corporation are entitled to vote separately as a class upon any matter at
such meeting, any adjournment of the meeting in respect of action by such class
upon such matter shall be determined by the holders of a majority of the shares
of such class present in person or represented by proxy and entitled to vote at
such meeting. When a meeting is adjourned to another time or place, notice need
not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken. At the adjourned
meeting, the stockholders, or the holders of any class of stock entitled to vote
separately as a class, as the case may be, may transact any business which might
have been transacted by them at the original meeting.
 
                                       1
<PAGE>
If the adjournment is for more than thirty days, or if after the adjournment a
new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
adjourned meeting.
 
    SECTION 6.  ORGANIZATION.  The Chief Executive Officer, or, in the absence
of the Chief Executive Officer, the President, or, in the absence of the Chief
Executive Officer and the President, a Vice President shall call all meetings of
the stockholders to order, and shall act as Chairman of such meetings. In the
absence of the Chief Executive Officer, the President and all of the Vice
Presidents, the holders of a majority in number of the shares of stock of the
Corporation present in person or represented by proxy and entitled to vote at
such meeting shall elect a Chairman.
 
    The Secretary of the Corporation shall act as Secretary of all meetings of
the stockholders; but in the absence of the Secretary, the Chairman may appoint
any person to act as Secretary of the meeting. It shall be the duty of the
Secretary to prepare and make, at least ten days before every meeting of
stockholders, a complete list of stockholders entitled to vote at such meeting,
arranged in alphabetical order and showing the address of each stockholder and
the number of shares registered in the name of each stockholder. Such list shall
be open, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting or, if not so
specified, at the place where the meeting is to be held, for the ten days next
preceding the meeting, to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, and shall be produced
and kept at the time and place of the meeting during the whole time thereof and
subject to the inspection of any stockholder who may be present.
 
    SECTION 7.  VOTING.  Except as otherwise provided in the Certificate of
Incorporation or by law, each stockholder shall be entitled to one vote for each
share of the capital stock of the Corporation registered in the name of such
stockholder upon the books of the Corporation. Each stockholder entitled to vote
at a meeting of stockholders or to express consent or dissent to corporate
action in writing without a meeting may authorize another person or persons to
act for him or her by proxy, but no such proxy shall be voted or acted upon
after three years from its date, unless the proxy provides for a longer period.
When directed by the presiding officer or upon the demand of any stockholder,
the vote upon any matter before a meeting of stockholders shall be by ballot.
Except as otherwise provided by law or by the Certificate of Incorporation,
Directors shall be elected by a plurality of the votes cast at a meeting of
stockholders by the stockholders entitled to vote in the election and, whenever
any corporate action, other than the election of Directors is to be taken, it
shall be authorized by a majority of the votes cast at a meeting of stockholders
by the stockholders entitled to vote thereon.
 
    Shares of the capital stock of the Corporation belonging to the Corporation
or to another corporation, if a majority of the shares entitled to vote in the
election of directors of such other corporation is held, directly or indirectly,
by the Corporation, shall neither be entitled to vote nor be counted for quorum
purposes.
 
    SECTION 8.  INSPECTORS.  When required by law or directed by the presiding
officer or upon the demand of any stockholder entitled to vote, but not
otherwise, the polls shall be opened and closed, the proxies and ballots shall
be received and taken in charge, and all questions touching the qualification of
voters, the validity of proxies and the acceptance or rejection of votes shall
be decided at any meeting of the stockholders by one or more Inspectors who may
be appointed by the Board of Directors before the meeting, or if not so
appointed, shall be appointed by the presiding officer at the meeting. If any
person so appointed fails to appear or act, the vacancy may be filled by
appointment in like manner. Each inspector, before entering upon the discharge
of his duties, shall take and sign an oath faithfully to execute the duties of
inspector with strict impartiality and according to the best of his ability.
 
    SECTION 9.  CONSENT OF STOCKHOLDERS IN LIEU OF MEETING.  Any action required
to be taken at any annual or special meeting of stockholders of the Corporation,
or any action which may be taken at any annual or special meeting of the
stockholders, may be taken without a meeting, without prior notice and
 
                                       2
<PAGE>
without a vote, if a consent or consents in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted and shall be delivered to the Corporation by delivery to its
registered office in Minnesota, its principal place of business, or an officer
or agent of the Corporation having custody of the book in which proceedings of
meetings of stockholders are recorded. Delivery made to the Corporation's
registered office shall be made by hand or by certified or registered mail,
return receipt requested.
 
    Every written consent shall bear the date of signature of each stockholder
who signs the consent and no written consent shall be effective to take the
corporate action referred to therein unless, within sixty (60) days of the date
on which the earliest dated consent is delivered to the Corporation, a written
consent or consents signed by a sufficient number of holders to take action are
delivered to the Corporation in the manner prescribed in the first paragraph of
this Section.
 
                                   ARTICLE II
                               BOARD OF DIRECTORS
 
    SECTION 1.  NUMBER AND TERM OF OFFICE.  The business and affairs of the
Corporation shall be managed by or under the direction of a Board of Directors,
none of whom need be stockholders of the Corporation. The number of Directors
constituting the Board of Directors shall be fixed from time to time by
resolution passed by a majority of the Board of Directors. The Directors shall,
except as hereinafter otherwise provided for filling vacancies, be elected at
the annual meeting of stockholders, and shall hold office until their respective
successors are elected and qualified or until their earlier resignation or
removal.
 
    SECTION 2.  REMOVAL, VACANCIES AND ADDITIONAL DIRECTORS.  The stockholders
may, at any special meeting, the notice of which shall state that it is called
for that purpose, remove, with or without cause, any Director and fill the
vacancy; provided that whenever any Director shall have been elected by the
holders of any class of stock of the Corporation voting separately as a class
under the provisions of the Certificate of Incorporation, such Director may be
removed and the vacancy filled only by the holders of that class of stock voting
separately as a class. Vacancies caused by any such removal and not filled by
the stockholders at the meeting at which such removal shall have been made, or
any vacancy caused by the death or resignation of any Director or for any other
reason, and any newly created directorship resulting from any increase in the
authorized number of Directors, may be filled by the affirmative vote of a
majority of the Directors then in office, although less than a quorum, and any
Director so elected to fill any such vacancy or newly created directorship shall
hold office until his or her successor is elected and qualified or until his or
her earlier resignation or removal.
 
    When one or more Directors shall resign effective at a future date, a
majority of the Directors then in office, including those who have so resigned,
shall have power to fill such vacancy or vacancies, the vote thereon to take
effect when such resignation or resignations shall become effective, and each
Director so chosen shall hold office as herein provided in connection with the
filling of other vacancies.
 
    SECTION 3.  PLACE OF MEETING.  The Board of Directors may hold its meetings
in such place or places in the State of Minnesota or outside the State of
Minnesota as the Board from time to time shall determine.
 
    SECTION 4.  REGULAR MEETINGS.  Regular meetings of the Board of Directors
shall be held at such times and places as the Board from time to time by
resolution shall determine. No further notice shall be required for any regular
meeting of the Board of Directors; but a copy of every resolution fixing or
changing the time or place of regular meetings shall be mailed to every Director
at least five days before the first meeting held in pursuance thereof.
 
                                       3
<PAGE>
    SECTION 5.  SPECIAL MEETINGS.  Special meetings of the Board of Directors
shall be held whenever called by direction of any two of the Directors then in
office.
 
    Notice of the day, hour and place of holding of each special meeting shall
be given by mailing the same at least two days before the meeting or by causing
the same to be transmitted by facsimile, telegram or telephone at least one day
before the meeting to each Director. Unless otherwise indicated in the notice
thereof, any and all business other than an amendment of these By-Laws may be
transacted at any special meeting, and an amendment of these By-Laws may be
acted upon if the notice of the meeting shall have stated that the amendment of
these By-Laws is one of the purposes of the meeting. At any meeting at which
every Director shall be present, even though without any notice, any business
may be transacted, including the amendment of these By-Laws.
 
    SECTION 6.  QUORUM.  Subject to the provisions of Section 2 of this Article
II, a majority of the members of the Board of Directors in office (but in no
case less than one-third of the total number of Directors nor less than two
Directors) shall constitute a quorum for the transaction of business and the
vote of the majority of the Directors present at any meeting of the Board of
Directors at which a quorum is present shall be the act of the Board of
Directors. If at any meeting of the Board there is less than a quorum present, a
majority of those present may adjourn the meeting from time to time.
 
    SECTION 7.  ORGANIZATION.  A Chairman of the Board shall preside at all
meetings of the Board of Directors. The Chairman shall be elected from the
Directors present at such meeting of the Board of Directors. The Secretary of
the Corporation shall act as Secretary of all meetings of the Directors; but in
the absence of the Secretary, the Chairman may appoint any person to act as
Secretary of the meeting.
 
    SECTION 8.  COMMITTEES.  The Board of Directors may designate one or more
committees including, without limitation, compensation and audit committees,
each committee to consist of one or more of the Directors of the Corporation.
The Board may designate one or more Directors as alternate members of any
committee who may replace any absent or disqualified member at any meeting of
the committee. In the absence or disqualification of a member of a committee,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not such member or members constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board, shall have and
may exercise all the powers and authority of the Board of Directors in the
management of the business and the affairs of the Corporation, and may authorize
the seal of the Corporation to be affixed to all papers which may require it;
but no such committee shall have the power or authority in reference to
approving or adopting, or recommending to the stockholders, any action or matter
expressly required by law to be submitted to stockholders for approval, or
adopting, amending or repealing these By-laws.
 
    SECTION 9.  CONFERENCE TELEPHONE MEETINGS.  Unless otherwise restricted by
the Certificate of Incorporation or by these By-Laws, the members of the Board
of Directors or any committee designated by the Board, may participate in a
meeting of the Board or such committee, as the case may be, by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.
 
    SECTION 10.  CONSENT OF DIRECTORS OR COMMITTEE IN LIEU OF MEETING.  Unless
otherwise restricted by the Certificate of Incorporation or by these By-Laws,
any action required or permitted to be taken at any meeting of the Board
Directors, or of any committee thereof, may be taken without a meeting if all
members of the Board or committee, as the case may be, consent thereto in
writing and the writing or writings are filed with the minutes of proceedings of
the Board or committee, as the case may be.

The President, the Chief Executive Officer, one or more Vice Presidents, the
Secretary and the Treasurer shall be elected by the Board of Directors at its
first meeting after each annual meeting of the stockholders. The failure to hold
such election shall not of itself terminate the term of office of any officer.
All officers shall hold office at the pleasure of the Board of Directors. Any
officer may resign at any time upon written notice to the Corporation. Officers
may, but need not, be Directors. Any number of offices may be held by the same
person.
 
    All officers, agents and employees shall be subject to removal, with or
without cause, at any time by the Board of Directors. The removal of an officer
without cause shall be without prejudice to his or her contract rights, if any.
The election or appointment of an officer shall not of itself create contract
rights. All agents and employees other than officers elected by the Board of
Directors shall also be subject to removal, with or without cause, at any time
by the officers appointing them.
 
    Any vacancy caused by the death, resignation or removal of any officer, or
otherwise, may be filled by the Board of Directors, and any officer so elected
shall hold office at the pleasure of the Board of Directors.

<PAGE>
shall at all reasonable times be open to the examination of any Director, upon
application, at the office of the Corporation during business hours. The
Secretary shall have all powers and shall perform all duties incident to the
office of Secretary, and shall also have such other powers and shall perform
such other duties as may from time to time be assigned by these By-Laws or by
the Board of Directors, the Chief Executive Officer or the President.
 
    SECTION 6.  POWERS AND DUTIES OF THE TREASURER.  The Treasurer shall have
custody of, and when proper, shall pay out, disburse or otherwise dispose of,
all funds and securities of the Corporation. The Treasurer may endorse on behalf
of the Corporation for collection checks, notes and other obligations and shall
deposit the same to the credit of the Corporation in such bank or banks or
depositary or depositaries as the Board of Directors may designate; shall sign
all receipts and vouchers for payments made to the Corporation, shall enter or

the Board of Directors, the Chief Executive Officer or the President.
 
    The Board of Directors may from time to time by resolution delegate to any

or Assistant Secretaries any of the powers or duties herein assigned to the

    SECTION 8.  GIVING OF BOND BY OFFICERS.  All officers of the Corporation, if

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    SECTION 1.  RIGHT TO INDEMNIFICATION.  Each person who was or is made a
party or is threatened to be made a party to or is otherwise involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter, a "Proceeding"), by reason of the fact that he or
she is or was a director or officer of the Corporation or is or was serving at
the request of the Corporation as a director,
 
                                       6
<PAGE>
officer, employee or agent of another corporation or of a partnership, joint
venture, trust or other enterprise, including service with respect to an
employee benefit plan (hereinafter, an "Indemnitee"), whether the basis of such
Proceeding is alleged action in an official capacity as a director, officer,
employee or agent or in any other capacity while serving as a director, officer,
employee or agent shall be indemnified and held harmless by the Corporation to
the fullest extent authorized by the Minnesota Business Corporation Act, as the
same exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than permitted prior thereto), against all
expense, liability and loss (including attorneys' fees, judgments, fines, ERISA
excise taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such Indemnitee in connection therewith and such indemnification
shall continue as to an Indemnitee who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the Indemnitee's heirs,
executors and administrators; PROVIDED, HOWEVER, that, except as provided in
Section 3 of this Article IV with respect to Proceedings to enforce rights to
indemnification, the Corporation shall indemnify any such Indemnitee in
connection with a Proceeding (or part thereof) initiated by such Indemnitee only
if such Proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation.
 
    SECTION 2.  RIGHT TO ADVANCEMENT OF EXPENSES.  The right to indemnification
conferred in Section 1 of this Article IV shall include the right to be paid by
the Corporation the expenses incurred in defending any Proceeding for which such
right to indemnification is applicable in advance of its final disposition
(hereinafter, an "Advancement of Expenses"); PROVIDED, HOWEVER, that, if the
Minnesota Business Corporation Act requires, an Advancement of Expenses incurred
by an Indemnitee in his or her capacity as a director or officer (and not in any
other capacity in which service was or is rendered by such Indemnitee,
including, without limitation, service to an employee benefit plan) shall be
made only upon delivery to the Corporation of an undertaking (hereinafter, an
"Undertaking"), by or on behalf of such Indemnitee, to repay all amounts so
advanced if it shall ultimately be determined by final judicial decision from
which there is no further right to appeal (hereinafter, a "Final Adjudication")
that such Indemnitee is not entitled to be indemnified for such expenses under
this Section or otherwise.
 
    SECTION 3.  RIGHT OF INDEMNITEE TO BRING SUIT.  The rights to
indemnification and to the advancement of expenses conferred in Sections 1 or 2
of this Article IV shall be contract rights. If a claim under Sections 1 or 2 of
this Article IV is not paid in full by the Corporation within sixty days after a
written claim has been received by the Corporation, except in the case of a
claim for an Advancement of Expenses, in which case the applicable period shall
be twenty days, the Indemnitee may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim. If successful in whole or
in part in any such suit, or in a suit brought by the Corporation to recover an
Advancement of Expenses pursuant to the terms of an Undertaking, the Indemnitee
shall be entitled to be paid also the expense of prosecuting or defending such
suit. In (i) any suit brought by the Indemnitee to enforce a right to
indemnification hereunder (but not in a suit brought by the Indemnitee to
enforce a right to an Advancement of Expenses), it shall be a defense that, and
(ii) in any suit by the Corporation to recover an Advancement of Expenses
pursuant to the terms of an Undertaking the Corporation shall be entitled to
recover such expenses upon a Final Adjudication that, the Indemnitee has not met
any applicable standard for indemnification set forth in the Minnesota Business
Corporation Act. Neither the failure of the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of the
Indemnitee is proper in the circumstances because the Indemnitee has met the
applicable standard of conduct set forth in the Minnesota Business Corporation
Act, nor an actual determination by the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the Indemnitee
has not met such applicable standard of conduct, shall create a presumption that
the Indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the Indemnitee, be a defense to such suit. In any suit
brought by the Indemnitee to enforce a right to indemnification or to an
Advancement of Expenses hereunder, or by the Corporation to recover an
Advancement of Expenses pursuant to the terms of an Undertaking, the burden
 
                                       7
<PAGE>
of proving that the Indemnitee is not entitled to be indemnified, or to such
Advancement of Expenses, under this Section or otherwise shall be on the
Corporation.
 
    SECTION 4.  NON-EXCLUSIVITY OF RIGHTS.  The rights to indemnification and to
the Advancement of Expenses conferred in this Article IV shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, the Corporation's Certificate of Incorporation, By-law, agreement, vote
of stockholders or disinterested directors or otherwise.
 
    SECTION 5.  INSURANCE.  The Corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the Minnesota Business Corporation Act.
 
    SECTION 6.  INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE CORPORATION.  The
Corporation may, to the extent authorized from time to time by the Board of
Directors, grant rights to indemnification, and to the Advancement of Expenses
to any employee or agent of the Corporation to the fullest extent of the
provisions of this Article IV with respect to the indemnification and
Advancement of Expenses of directors and officers of the Corporation.
 
                                   ARTICLE V
                             STOCK-SEAL-FISCAL YEAR
 
    SECTION 1.  CERTIFICATES FOR SHARES OF STOCK.  The certificates for shares
of stock of the Corporation shall be in such form, not inconsistent with the
Certificate of Incorporation, as shall be approved by the Board of Directors.
All certificates shall be signed by the Chief Executive Officer, the President
or a Vice President and by the Secretary or an Assistant Secretary or the
Treasurer or an Assistant Treasurer, and shall not be valid unless so signed.
 
    In case any officer or officers who shall have signed any such certificate
or certificates shall cease to be such officer or officers of the Corporation,
whether because of death, resignation or otherwise, before such certificate or
certificates shall have been delivered by the Corporation, such certificate or
certificates may nevertheless be issued and delivered as though the person or
persons who signed such certificate or certificates had not ceased to be such
officer or officers of the Corporation.
 
    All certificates for shares of stock shall be consecutively numbered as the
same are issued. The name of the person owning the shares represented thereby
with the number of such shares and the date of issue thereof shall be entered on
the books of the Corporation.
 
    Except as hereinafter provided, all certificates surrendered to the
Corporation for transfer shall be canceled, and no new certificates shall be
issued until former certificates for the same number of shares have been
surrendered and canceled.
 
    SECTION 2.  LOST, STOLEN OR DESTROYED CERTIFICATES.  Whenever a person
owning a certificate for shares of stock of the Corporation alleges that it has
been lost, stolen or destroyed, he or she shall file in the office of the
Corporation an affidavit setting forth, to the best of his or her knowledge and
belief, the time, place and circumstances of the loss, theft or destruction,
and, if required by the Board of Directors, a bond of indemnity or other
indemnification sufficient in the opinion of the Board of Directors to indemnify
the Corporation and its agents against any claim that may be made against it or
them on account of the alleged loss, theft or destruction of any such
certificate or the issuance of a new certificate in replacement therefor.
Thereupon, the Corporation may cause to be issued to such person a new
certificate in replacement for the certificate alleged to have been lost, stolen
or destroyed. Upon the stub of every new certificate so issued shall be noted
the fact of such issue and the number, date and the name of the registered owner
of the lost, stolen or destroyed certificate in lieu of which the new
certificate is issued.
 
                                       8
<PAGE>
    SECTION 3.  TRANSFER OF SHARES.  Shares of stock of the Corporation shall be
transferred on the books of the Corporation by the holder thereof, in person or
by his or her attorney duly authorized in writing, upon surrender and
cancellation of certificates for the number of shares of stock to be
transferred, except as provided in Section 2 of this Article IV.
 
    SECTION 4.  REGULATIONS.  The Board of Directors shall have power and
authority to make such rules and regulations as it may deem expedient concerning
the issue, transfer and registration of certificates for shares of stock of the
Corporation.
 
    SECTION 5.  RECORD DATE.  In order that the Corporation may determine the
stockholders entitled to notice of, or to vote at, any meeting of stockholders,
or to receive payment of any dividend or other distribution or allotment of any
rights or to exercise any rights in respect of any change, conversion or
exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date on
which the resolution fixing the record date is adopted and which record date
shall not be more than sixty (60) nor less than ten (10) days before the date of
any meeting of stockholders, nor more than sixty (60) days prior to the time for
such other action as hereinbefore described; PROVIDED, HOWEVER, that if no
record date is fixed by the Board of Directors, the record date for determining
stockholders entitled to notice of, or to vote at, a meeting of stockholders
shall be at the close of business on the day next preceding the day on which
notice is given or, if notice is waived, at the close of business on the day
next preceding the day on which the meeting is held, and, for determining
stockholders entitled to receive payment of any dividend or other distribution
or allotment of rights or to exercise any rights of change, conversion or
exchange of stock or for any other purpose, the record date shall be at the
close of business on the day on which the Board of Directors adopts a resolution
relating thereto.
 
    A determination of stockholders of record entitled to notice of, or to vote
at, a meeting of stockholders shall apply to any adjournment of the meeting;
PROVIDED, HOWEVER, that the Board of Directors may fix a new record date for the
adjourned meeting.
 
    In order that the Corporation may determine the stockholders entitled to
consent to corporate action in writing without a meeting, the Board of Directors
may fix a record date, which shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which record date shall be not more than ten (10) days after the date upon which
the resolution fixing the record date is adopted. If no record date has been
fixed by the Board of Directors and no prior action by the Board of Directors is
required by the Minnesota Business Corporation Act, the record date shall be the
first date on which a signed written consent setting forth the action taken or
proposed to be taken is delivered to the Corporation in the manner prescribed by
Article I, Section 9 hereof. If no record date has been fixed by the Board of
Directors and prior action by the Board of Directors is required by the
Minnesota Business Corporation Act with respect to the proposed action by
written consent of the stockholders, the record date for determining
stockholders entitled to consent to corporate action in writing shall be at the
close of business on the day on which the Board of Directors adopts the
resolution taking such prior action.
 
    SECTION 6.  DIVIDENDS.  Subject to the provisions of the Certificate of
Incorporation, the Board of Directors shall have power to declare and pay
dividends upon shares of stock of the Corporation, but only out of funds
available for the payment of dividends as provided by law.
 
    Subject to the provisions of the Certificate of Incorporation, any dividends
declared upon the stock of the Corporation shall be payable on such date or
dates as the Board of Directors shall determine. If the date fixed for the
payment of any dividend shall in any year fall upon a legal holiday, then the
dividend payable on such date shall be paid on the next day not a legal holiday.
 
    SECTION 7.  CORPORATE SEAL.  The Board of Directors shall provide a suitable
seal, containing the name of the Corporation, which seal shall be kept in the
custody of the Secretary. A duplicate of the seal
 
                                       9
<PAGE>
may be kept and be used by any officer of the Corporation designated by the
Board of Directors, the Chief Executive Officer or the President.
 
    SECTION 8.  FISCAL YEAR.  The fiscal year of the Corporation shall be such
fiscal year as the Board of Directors from time to time by resolution shall
determine.

be signed and, if so required by the Board of Directors, countersigned by such
officers of the Corporation and/or other persons as the Board of Directors from
time to time shall designate.

contracted on behalf of the Corporation except as authorized by the Board of
Directors. When authorized to do so, any officer or agent of the Corporation may
effect loans and advances for the Corporation from any bank, trust company or
other institution or from any firm, corporation or individual, and for such
loans and advances may make, execute and deliver promissory notes, bonds or
other evidences of indebtedness of the Corporation. When authorized so to do,
any officer or agent of the Corporation may pledge, hypothecate or transfer, as
security for the payment of any and all loans, advances, indebtedness and
liabilities of the Corporation, any and all stocks, securities and other
personal property at any time held by the Corporation, and to that end may
endorse, assign and deliver the same. Such authority may be general or confined
to specific instances.
 
    SECTION 3.  CONTRACTS.  Except as otherwise provided in these By-Laws or by
law or as otherwise directed by the Board of Directors, the Chief Executive
Officer, the President or any Vice President shall be authorized to execute and
deliver, in the name and on behalf of the Corporation, all agreements, bonds,

Executive Officer, the President or any Vice President designated by the Board
of Directors may authorize any other officer, employee or agent to execute and
deliver, in the name and on behalf of the Corporation, agreements, bonds,

own account or in a fiduciary or other capacity, and, if appropriate, to affix
the seal of the Corporation thereto. The grant of such authority by the Board or
any such officer may be general or confined to specific instances.
 
    SECTION 4.  WAIVERS OF NOTICE.  Whenever any notice whatever is required to
be given by law, by the Certificate of Incorporation or by these By-Laws to any
person or persons, a waiver thereof in writing, signed by the person or persons
entitled to the notice, whether before or after the time stated therein, shall
be deemed equivalent thereto.

December 11, 1998
 
Board of Directors
Vaughn Communications, Inc.
5050 West 78(th) Street
Minneapolis, MN 55435
 
Gentlemen:
 
    We understand that Vaughn Communications, Inc. ("Vaughn") has agreed to sell
all of its issued and outstanding shares of Common Stock, par value $0.10 per
share (the "Common Stock"), to Allied Digital, Inc. ("Allied"). Pursuant to the
Agreement and Plan of Merger dated December 11, 1998 (the "Merger Agreement"),
among Vaughn, Allied and Allied's wholly owned subsidiary, Twin Acquisition
Corp. ("Merger Sub"), Allied proposes to acquire all of Vaughn's issued and
outstanding shares of Common Stock for $10.00 per share in cash (the
"Consideration") through a merger of Merger Sub with and into Vaughn, with
Vaughn as the surviving corporation (the "Merger"), subject to the rights of
Dissenting Stockholders (as such term is defined in the Merger Agreement).
 
    We also understand that following the Merger, Vaughn will be reincorporated
in Delaware by merging with and into a Delaware corporation of the same name
(Vaughn Communications, Inc.) The Merger is defined herein as the Transaction.
 
    You have requested our opinion as to whether the Consideration to be
received by the stockholders of Vaughn in the Transaction is fair, from a
financial point of view, to the stockholders of Vaughn as of the date hereof.
 
    For the purposes of the opinion set forth herein, we have, among other
things,
 
    - Reviewed the agreement and plan of merger (the "Merger Agreement") by and
      between Vaughn, Allied and Twin Acquisition Corp. in substantially final
      form;
 
    - Reviewed a draft of Vaughn's merger proxy statement dated December 9,
      1998, in substantially final form;
 
    - Reviewed Vaughn's annual report on Forms 10-K for the years ended January
      31, 1997, and 1998;
 
    - Reviewed Vaughn's quarterly reports on Forms 10-Q for the three months
      ended July 30, 1998 and October 31, 1998;
 
    - Reviewed Vaughn's current report on Form 8-K with a Date of Report of
      November 16, 1998;
 
    - Reviewed certain non-public operating and financial information, including
      financial projections, relating to Vaughn's business prepared by
      management of Vaughn;
 
    - Interviewed certain members of Vaughn's management to discuss its
      operations, financial statements and future prospects;
 
    - Reviewed the historical share prices and trading volumes of Vaughn's
      Common Stock;
 
    - Reviewed premiums paid in recent merger transactions of comparable size;
 
    - Reviewed publicly available financial data and stock market performance
      data of other publicly traded multi-media companies, which we deemed
      comparable to Vaughn;
 
    - Reviewed the terms of selected recent acquisitions of companies which we
      deemed comparable to Vaughn;
 
                                      B-1
<PAGE>
    - Reviewed termination fees agreed to on recent transactions of comparable
      size; and
 
    - Conducted such other studies, analyses, inquiries and investigations, as
      we deemed appropriate.
 
    In arriving at our opinion, we have considered such factors as we have
deemed relevant including, but not limited to: (i) the historical market prices
and trading volume of the Common Stock of Vaughn, (ii) premiums in recent merger
transactions of comparable size, (iii) the transaction values on business
combinations which we believe comparable to Vaughn relative to sales, earnings
before interest, taxes, depreciation and amortization ("EBITDA"), and earnings
before interest and taxes ("EBIT"), (iv) the market value of publicly held
companies we deemed comparable to Vaughn relative to sales, EBITDA, EBIT, and
net income, (v) a valuation for Vaughn (on a per share basis) based on a
discounted cash flow analysis, and (vi) other items we deemed to be relevant.
 
    During our review, we have relied upon and assumed, without independent
verification, the accuracy and completeness of the financial and other
information provided, and have further relied upon the assurances of management
that they are unaware of any facts that would make the information provided to
us to be incomplete or misleading for the purposes of this opinion. As our
opinion encompasses forward looking valuation techniques such as the discounted
cash flow analysis, we have assumed that the financial projections which we
reviewed to have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performance of each
company. Our opinion is necessarily based on the economic, market, and other
conditions as in effect on, and the information made available to us as of, the
date hereof. In arriving at our opinion, we have not performed any independent
appraisal of the assets of Vaughn. We disclaim any undertaking or obligation to
advise any person of any change in any fact or matter affecting our opinion
which may come or be brought to our attention after the date of this opinion.
 
    We have acted as financial advisor to the Special Committee of the Board of
Directors of Vaughn in connection with the sale of the Company and will receive
a fee for such services. This opinion is for the use and benefit of the Board of
Directors of Vaughn in its consideration of the Merger.
 
    It is understood that this opinion will be included in its entirety in a
proxy statement or other document distributed to the stockholders of Vaughn in
connection with the Transaction and this constitutes our express written
approval for that purpose. It is understood that this opinion shall be used by
you solely in connection with your consideration of the fairness of the
Transaction to the stockholders of Vaughn and for no other purpose, and Vaughn
will not furnish this opinion or any other material prepared by us to any other
person or use or refer to this opinion for any other purpose without our prior
written approval. However, no summary of, or excerpt from, this opinion may be
used, and no published public reference (other than as provided in the preceding
sentence) to this opinion may be made except with our prior express approval.
 
    This opinion does not constitute a recommendation to any stockholder of
Vaughn as to whether such stockholder should vote to approve the Merger, or as
to any other actions which such stockholder should take in conjunction with the
Transaction. This opinion relates solely to the question of fairness to the
Vaughn stockholders, from a financial point of view, of the Transaction as
currently proposed. Further, we express no opinion herein as to the structure,
terms or effect of any other aspect of the Transaction, including, without
limitation, any effects resulting from the application of any bankruptcy,
fraudulent conveyance or other federal or state insolvency law or of any pending
or threatened litigation affecting Vaughn.
 
    Based on the foregoing, we are of the opinion that the Consideration to be
received by the stockholders of Vaughn in the Transaction is fair, from a
financial point of view, to the stockholders of Vaughn as of the date hereof.
 
Very truly yours,
 
EVEREN Securities, Inc.

    SECTIONS 302A.471 AND 302A.473 OF THE MINNESOTA BUSINESS CORPORATION ACT
 
302A.471. RIGHTS OF DISSENTING SHAREHOLDERS

dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:
 
        (a) An amendment of the articles that materially and adversely affects
    the rights or preferences of the shares of the dissenting shareholder in
    that it:
 
           (1) alters or abolishes a preferential right of the shares;
 
           (2) creates, alters, or abolishes a right in respect of the
       redemption of the shares, including a provision respecting a sinking fund
       for the redemption or repurchase of the shares;
 
           (3) alters or abolishes a preemptive right of the holder of the
       shares to acquire shares, securities other than shares, or rights to
       purchase shares or securities other than shares;
 
           (4) excludes or limits the right of a shareholder to vote on a
       matter, or to cumulate votes, except as the right may be excluded or
       limited through the authorization or issuance of securities of an
       existing or new class or series with similar or different voting rights;
       except that an amendment to the articles of an issuing public corporation
       that provides that section 302A.671 does not apply to a control share
       acquisition does not give rise to the right to obtain payment under this
       section;
 
        (b) A sale, lease, transfer, or other disposition of all or
    substantially all of the property and assets of the corporation, but not

    shareholders in accordance with their respective interests within one year
    after the date of disposition;
 
        (c) A plan of merger, whether under this chapter or under chapter 322B,
    to which the corporation is a party, except as provided in subdivision 3;
 
        (d) A plan of exchange, whether under this chapter or under chapter
    322B, to which the corporation is a party as the corporation whose shares
    will be acquired by the acquiring corporation, if the shares of the
    shareholder are entitled to be voted on the plan; or
 
        (e) Any other corporate action taken pursuant to a shareholder vote with
    respect to which the articles, the bylaws, or a resolution approved by the
    board directs that dissenting shareholders may obtain payment for their
    shares.
 
    SUBD. 2. BENEFICIAL OWNERS.
 
        (a) A shareholder shall not assert dissenters rights as to less than all
    of the shares registered in the name of the shareholder, unless the
    shareholder dissents with respect to all the shares that are beneficially
    owned by another person but registered in the name of the shareholder and
    discloses the name and address of each beneficial owner on whose behalf the

    dissent if no shareholder vote was required, a notice that contains:
 
           (1) The address to which a demand for payment and certificates of
       certificated shares must be sent in order to obtain payment and the date

    SUBD. 5. PAYMENT; RETURN OF SHARES.
 
        (a) After the corporate action takes effect, after the corporation
    receives a valid demand for payment, whichever is later, the corporation
    shall remit to each dissenting shareholder who has complied with
    subdivisions 3 and 4 the amount the corporation estimates to be the fair
    value of the shares, plus interest, accompanied by:
 
           (1) The corporation's closing balance sheet and statement of income
       for a fiscal year ending not more than 16 months before the effective
       date of the corporate action, together with the latest available interim
       financial statements;
 
           (2) An estimate by the corporation of the fair value of the shares
       and a brief description of the method used to reach the estimate; and
 
           (3) A copy of section 302A.471 and this section, and a brief
       description of the procedure to be followed in demanding supplemental
       payment.
 
        (b) The corporation may withhold the remittance described in paragraph
    (a) from a person who was not a shareholder on the date the action dissented
    from was first announced to the public or who is dissenting on behalf of a
    person who was not a beneficial owner on that date. If the dissenter has
    complied with subdivisions 3 and 4, the corporation shall forward to the
    dissenter the materials described in paragraph (a), a statement of the
    reason for withholding the remittance, and an offer to pay to the dissenter
    the amount listed in the materials if the dissenter agrees to accept that
    amount in full satisfaction. The dissenter may decline the offer and demand
    payment under subdivision 6. Failure to do so entitles the dissenter only to
    the amount offered. If the dissenter makes demand, subdivisions 7 and 8
    apply.
 
        (c) If the corporation fails to remit payment within 60 days of the
    deposit of certificates or the imposition of transfer restrictions on
    uncertificated shares, it shall return all deposited certificates and cancel
    all transfer restrictions. However, the corporation may again give notice
    under subdivision 4 and require deposit or restrict transfer at a later
    time.
 
    SUBD. 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.
 
    SUBD. 7. PETITION; DETERMINATION. If the corporation receives a demand under
subdivision 6, it shall, within 60 days after receiving the demand, either pay
to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in
 
                                      C-3
<PAGE>
this state in which the last registered office of the constituent corporation
was located. The petition shall name as parties all dissenters who have demanded
payment under subdivision 6 and who have not reached agreement with the
corporation. The corporation shall, after filing the petition, serve all parties
with a summons and copy of the petition under the rules of civil procedure.
Nonresidents of this state may be served by registered or certified mail or by
publication as provided by law. Except as otherwise provided, the rules of civil
procedure apply to this proceeding. The jurisdiction of the court is plenary and
exclusive. The court may appoint appraisers, with powers and authorities the
court deems proper, to receive evidence on and recommend the amount of the fair
value of the shares. The court shall determine whether the shareholder or
shareholders in question have fully complied with the requirements of this
section, and shall determine the fair value of the shares, taking into account
any and all factors the court finds relevant, computed by any method or
combination of methods that the court, in its discretion, sees fit to use,
whether or not used by the corporation or by a dissenter. The fair value of the
shares as determined by the court is binding on all shareholders, wherever
located. A dissenter is entitled to judgment in cash for the amount by which the
fair value of the shares as determined by the court, plus interest, exceeds the
amount, if any, remitted under subdivision 5, but shall not be liable to the
corporation for the amount, if any, by which the amount, if any, remitted to the
dissenter under subdivision 5 exceeds the fair value of the shares as determined
by the court, plus interest.
 
    SUBD. 8. COSTS; FEES; EXPENSES.
 
        (a) The court shall determine the costs and expenses of a proceeding
    under subdivision 7, including the reasonable expenses and compensation of
    any appraisers appointed by the court, and shall assess those costs and
    expenses against the corporation, except that the court may assess part or
    all of those costs and expenses against a dissenter whose action in
    demanding payment under subdivision 6 is found to be arbitrary, vexatious,
    or not in good faith.
 
        (b) If the court finds that the corporation has failed to comply
    substantially with this section, the court may assess all fees and expenses
    of any experts or attorneys as the court deems equitable. These fees and
    expenses may also be assessed against a person who has acted arbitrarily,
    vexatiously, or not in good faith in bringing the proceeding, and may be
    awarded to a party injured by those actions.
 
        (c) The court may award, in its discretion, fees and expenses to an
    attorney for the dissenters out of the amount awarded to the dissenters, if
    any.

    entitled at Law or in equity.

    of any right hereunder shall impair such right or be construed to be a

    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

unissued or reacquired shares ("SHARES") of Series C Preferred Stock, par value
$.01 per share, of the Company ("SERIES C PREFERRED"). Terms not otherwise
defined herein shall have the meanings ascribed thereto in the Agreement and

conditions:
 
    1  NUMBER OF OPTIONS.  Subject to the terms and conditions hereof, the
Company hereby grants to you, as of the Effective Time, one Option to purchase

    3.  VESTING/EXERCISE PERIOD.  The Option shall be fully vested and
exercisable on the date of grant. The Option shall expire on the tenth
anniversary of the date of grant unless sooner terminated pursuant to Section 5
thereof.
 
    4.  TRANSFERABILITY.  Neither the Option nor any portion thereof shall be
transferable by you other than by will or the laws of descent and distribution,
and the Option may not be exercised by anyone other than you during your
lifetime.
 
    5.  SHARE REPURCHASE OR REDEMPTION.
 
        (a)  SALE EVENT.  If you undergo a cessation of employment during the
    term of this Option, you must exercise the Option within twenty calendar
    days of the date of such cessation or the Option shall be forfeited at the
    end of such twenty day period without any further rights therein, and the
    Shares you purchase (if any) will be subject to repurchase pursuant to the
    terms of Article IV of the Investors' Agreement, dated as of September 24,
    1998, as such agreement may have been or may be modified or amended from
    time to time (the "INVESTORS' AGREEMENT")
 
        (b)  SALE OF THE COMPANY.  Immediately upon the occurrence of a Sale of

    the Option shall be forfeited without any further rights therein, and the
    Shares you

<PAGE>
    purchase (if any) will be subject to redemption pursuant to the terms of the
    Certificate of Incorporation.
 
    6.  MANNER OF EXERCISE.  You must exercise the Option in whole (not in
part). You may exercise the Option only by giving the Chief Financial Officer of
the Company written notice by personal hand delivery to the Chief Financial

Officer.
 
    7.  PAYMENT OF EXERCISE PRICE.  If you exercise the Option, you must pay the

transferred to you on the exercise of the Option until the Company has received
the full payment pursuant to Section 2 and until the provisions of Section 8 are
satisfied.
 
    8.  DELIVERY OF SHARES AND COMPLIANCE WITH LAWS.

    then the date of delivery of such Shares shall be extended for the period
    necessary to complete such action.
 
        (b)  LISTING, QUALIFICATIONS, ETC.  The Option shall be subject to the
    requirement that if, at any time, counsel to the Company shall determine

    disclosure of nonpublic information or the satisfaction of any other
    condition is necessary as a condition of, or in connection with, the
    issuance or purchase of Shares thereunder, the Option may not be exercised
    unless such listing, registration, qualification, consent or approval,
    disclosure or satisfaction of such other condition shall have been effected
    or obtained on terms acceptable to the Company. Nothing herein shall be
    deemed to require the Company to apply for, effect or obtain such listing,

    condition.
