                                PROXY STATEMENT
                     FOR THE ANNUAL MEETING OF STOCKHOLDERS
                          To Be Held On August 9, 1995



   This proxy statement is furnished in connection with the solicitation of
proxies by and on behalf of the Board of Directors of ABIOMED, Inc., a Delaware
corporation with its principal executive offices at 33 Cherry Hill Drive,
Danvers, Massachusetts 01923 (the "Company"), for use at the Annual Meeting of
Stockholders to be held on August 9, 1995 and at any adjournment or adjournments
thereof (the "Meeting").  The cost of such solicitation will be borne by the
Company.  Certain of the officers and regular employees of the Company may
solicit proxies by correspondence, telephone or in person, without extra
compensation, and in addition the Company may engage _________________ to
perform additional solicitation for a fee not to exceed $______ plus reasonable
out of pocket expenses.  The Company may also pay to banks, brokers, nominees
and other fiduciaries their reasonable charges and expenses incurred in
forwarding proxy material to their principals.  It is expected that this proxy
statement and the accompanying proxy will be mailed to stockholders on or about
June 30, 1995.

   Only stockholders of record at the close of business on June 16, 1995 will be
entitled to receive notice of, and to vote at, the Meeting.  As of that date,
there were outstanding and entitled to vote 2,040,000 shares of Class A Common
Stock, $.01 par value (the "Class A Common Stock"), and 4,885,821 shares of
Common Stock, $.01 par value (the "Common Stock"), of the Company.  Holders of
Class A Common Stock have ten votes per share and holders of Common Stock have
one vote per share on all matters on which they are entitled to vote.  The
holders of Common Stock, voting as a separate class, are entitled to elect 25%
of the Board of Directors (rounded up to the nearest whole number), and the
balance of the directors are elected by the holders of both classes of common
stock, voting together as a single class.  Directors will be elected by a
plurality of the votes cast by holders of the classes of common stock entitled
to vote thereon.  Abstentions, including broker non-votes, will have no effect
on the outcome of the vote for the election of directors.  Since Proposals No.
2, 3 and 4 require the affirmative vote of a majority of the outstanding shares
of the relevant classes as indicated under those proposals, abstentions and
broker non-votes would have the same legal effect as a vote against those
proposals, even though that might not be the intent of the person voting or
giving the proxy.  Proposals No. 5 and 6 require the affirmative vote of a
majority of those votes present in person or by proxy at the Meeting and
entitled to be voted, provided a quorum is present.  Thus, abstentions have the
effect of a vote against Proposals 5 and 6, but a broker non-vote has no effect.

   THE ENCLOSED PROXY, IF EXECUTED AND RETURNED, WILL BE VOTED AS DIRECTED ON
THE PROXY OR, IN THE ABSENCE OF SUCH DIRECTION, FOR THE NOMINEES AS DIRECTORS
AND FOR PROPOSALS 2 THROUGH 6.  IF ANY OTHER MATTERS SHALL PROPERLY COME BEFORE
THE MEETING, THEY WILL BE VOTED BY THE PROXIES IN ACCORDANCE WITH THEIR BEST
JUDGMENT.  THE PROXY MAY BE REVOKED AT ANY TIME PRIOR TO EXERCISE BY FILING WITH
THE SECRETARY OF THE COMPANY A WRITTEN REVOCATION, BY EXECUTING A PROXY WITH A
LATER DATE, OR BY ATTENDING AND VOTING AT THE MEETING.

   The Company's Annual Report to Stockholders for the fiscal year ended March
31, 1995, including financial statements audited by Arthur Andersen & Co., LLP.
is being mailed to each of the stockholders simultaneously with this proxy
statement.

                                 PROPOSAL NO. 1
                             ELECTION OF DIRECTORS


   At the Meeting, six directors are to be elected.  If Proposal No. 2 is
approved, two nominees will be elected as Class I directors to serve an initial
term of one year, two nominees will be elected as Class II directors to serve an
initial term of two years, and two nominees will be elected as Class III
directors to serve an initial term of three years (or, in all cases, until their
successors have been elected and qualified).  After this year's election,
election of directors will be for three year terms.  If Proposal No. 2 is not
adopted, each director will serve for one year or until his successor is duly
elected and qualified.  The persons named below will be nominated by the Board
of Directors for election as directors.  The first four named persons are being
nominated for election to the offices for which holders of both Common Stock and
Class A Common Stock vote as a single class; Messrs. Henri A. Termeer and
Desmond H. O'Connell, Jr. are being nominated for election by the holders of
Common Stock, voting as a separate class.  With the exception of Desmond H.
O'Connell, Jr., all of these nominees are currently serving as directors of the
Company.

   If any nominee at the time of the election is unable or unwilling to serve or
is otherwise unavailable for election, and the Board of Directors designates
another nominee, the persons named as proxies will vote the proxy for such
substitute, if any.  The Board of Directors has no reason to believe that any of
the proposed nominees will be unable or unwilling to serve.  The proposed
nominees are not being nominated pursuant to any arrangement or understanding
with any person.

Information on Nominees

   Set forth below is certain biographical information furnished by the
nominees, and the class to which such nominee will be elected if Proposal No. 2
is approved.

(1)  Based upon the $7.25 closing price of the Company's Common Stock on
     March 31, 1995 on the NASDAQ National Market System minus the respective
     option exercise price.


      No options were granted to or exercised by the named executive officers
  during the fiscal year ended March 31, 1995.

  Compensation of Directors

     Directors who are not employees of the Company receive an advisory fee of
  $1,000 per quarter plus an additional $250 for attendance at each meeting of
  the Board of Directors or a committee thereof or consultation at the offices
  of the Company.

     Indemnification Agreements.  The Company has entered into indemnification
  agreements with each of its directors and anticipates that it will enter into
  similar agreements with any future directors.  The Company has also entered
  into similar agreements with certain of the Company's officers and top
  management personnel who are not also directors.  Generally, the
  indemnification agreements attempt to provide the maximum protection permitted
  by Delaware law with respect to indemnification of directors.

     The indemnification agreements provide that the Company will pay certain
  amounts incurred by a director or officer in connection with any civil or
  criminal action or proceeding and specifically including actions by or in the
  name of the Company (derivative suits) where the individual's involvement is
  by reason of the fact that he is or was a director or officer.  Such amounts
  include, to the maximum extent permitted by law, attorney's fees, judgments,
  civil or criminal fines, settlement amounts, and other expenses customarily
  incurred in connection with legal proceedings.  Under the indemnification
  agreements, a director or officer will not receive indemnification if he is
  found not

  to have acted in good faith and in a manner he reasonably believed to be in or
  not opposed to the best interests of the Company.

     The 1989 Non-Qualified Stock Option Plan for Non-Employee Directors.  The
  Company has a 1989 Non-Qualified Stock Option Plan for Non-Employee Directors
  (the "Directors Plan") which is more fully described under Proposal No. 6
  below.  Under the Directors Plan, options to purchase Common Stock are granted
  to directors of the Company who are not employees of the Company and who do
  not own or are not affiliated with any person who owns, directly or
  indirectly, more than 5% of the Company's outstanding voting stock are
  eligible to receive options under the Directors Plan (the "Eligible
  Directors").  The current Eligible Directors, among those persons nominated
  for election as directors at the Meeting, are Dr. Austen and Messrs. Fireman,
  O'Brien and Termeer.  No options were granted under the Directors Plan in the
  fiscal year ended March 31, 1995.  If Mr. O'Connell is elected as a director
  at the meeting, he will become an Eligible Director and will receive an option
  to purchase 12,500 shares under the Directors Plan.

  Insider Participation in Compensation Decisions

     Decisions regarding executive compensation are made by the Compensation
  Committee of the Board of Directors, which is composed of Dr. Austen and
  Messrs. Fireman and O'Brien.  The Compensation Committee also administers the
  Company's 1992 Combination Stock Option Plan (the "Combination Plan"),
  including determining the individuals to whom stock options are awarded, the
  terms upon which option grants are made, and the number of shares subject to
  each option granted under the Combination Plan.  No member of the Compensation
  Committee is a former or current officer or employee of the Company.  Dr.
  Lederman, while not a member of the Compensation Committee, makes
  recommendations to the Compensation Committee regarding executive officer
  compensation, including the awards of stock options, and often participates in
  their deliberations but does not vote on such matters.

  Compensation Committee Report on Executive Compensation

     The primary objectives of the Compensation Committee in developing
  executive compensation policies are to attract and retain superior talent to
  enable the Company to achieve its business objectives and to align the
  financial interests of its executive officers with the stockholders of the
  Company.  The compensation of executive officers consists of base
  compensation, bonus, the grant of options and participation in benefit plans
  generally available to employees.

     In setting overall compensation for the last fiscal year, the Compensation
  Committee reviewed the recommendations of the Chief Executive Officer and
  strove to maintain base compensation for the Company's executive officers at
  levels which the Compensation Committee believes are competitive with the
  compensation of comparable executive officers in similarly situated companies,
  while relying upon the Company's Combination Plan and informal bonus program
  to provide significant performance incentives.  For the last fiscal year,
  while the Compensation Committee considered the factors set forth below in
  reviewing an executive officer's compensation package, no particular weight
  was assigned to any of those factors.  Rather the overall compensation of each
  executive officer was reviewed as a whole, with substantial weight given to
  the Chief Executive Officer's recommendations.

                                       11
<PAGE>
 
     Under the Company's bonus program, a discretionary bonus may be paid to
  each executive officer.  In determining the bonus to be granted to each
  executive officer the Compensation Committee reviewed recommendations provided
  by the Chief Executive Officer based upon each executive officer's achievement
  of informal expectations and goals established with the Chief Executive
  Officer for the year, and the Company's performance during the year.  Such
  goals may include the officer's contribution to the short-term financial
  performance of the Company as well as achievements in forwarding the Company's
  research and development, which the Company believes will be important to its
  long-term success.  As reflected in the Summary Compensation Table, bonuses
  for fiscal 1995 were modest, reflecting the Company's stage of development.

     Each of the executive officers is eligible to receive grants of options
  under the Combination Plan. In determining the number of options to be granted
  to each executive officer, the Compensation Committee reviews recommendations
  provided by the Chief Executive Officer based upon the officer's position of
  responsibility and anticipated contribution to the Company, the number of
  shares of Common Stock subject to options held or previously granted to the
  officer, the individual performance of the officer and the number of shares of
  Common Stock held by the officer.

     During the fiscal year ended March 31, 1995, Dr. Lederman, the Chief
  Executive Officer of the Company, received a base salary of $122,320 and no
  bonus.  Dr. Lederman's base salary has remained constant since October, 1990.
  Dr. Lederman has never received any options to purchase stock of the Company,
  since the Company's option plans prohibit awards to 5% or larger stockholders.
  The Compensation Committee believes that the compensation of Dr. Lederman is
  low compared to his importance and contributions to the Company, and the
  compensation of chief executive officers of similarly situated companies.
  This low level of compensation reflects Dr. Lederman's request to limit his
  compensation during the year based upon the Company's stage of development.
  If not for this request, the Board of Directors would have set Dr. Lederman's
  compensation at a higher level to better reflect his importance and
  contributions to the Company.

                       INTRODUCTION TO CHARTER AMENDMENTS

     The Board of Directors unanimously has determined that certain amendments
  to the Company's Certificate of Incorporation are advisable and has
  unanimously voted to recommend them to the Company's stockholders for adoption
  at the 1995 Annual Meeting.  These amendments are being submitted in the form
  of three separate proposals:  (i) a proposal to create a classified Board of
  Directors and make certain related changes; (ii) a proposal directing the
  Board of Directors to consider all relevant factors in connection with certain
  business combinations; and (iii) a proposal to increase the number of
  authorized shares of Common Stock (collectively, the "Charter Amendments").
  The background, reasons and effects of the three proposals are set forth
  below, followed by a more detailed description of each proposal and how it
  would operate.

     Purposes and Effects

     At the present time, Dr. David M. Lederman, founder of the Company, and Dr.
  Param I Singh, by virtue of their ownership of all of the Class A Common
  Stock, hold 57.1% and 24.6%, respectively, of the total voting power of the
  Company's Common Stock.  However, in general, a transfer of any Class A Common
  Stock by Dr. Lederman will cause all of the outstanding Class A Common Stock
  automatically to be converted into Common Stock, and a transfer by Dr. Singh
  will cause the transferred shares to convert into Common Stock but will not
  effect the remaining shares of Class A Common Stock outstanding.  (There are
  limited exceptions to these provisions allowing transfer of Class A Common
  Stock to trusts controlled by one or the other or both of Dr. Lederman and Dr.
  Singh.)  Dr. Lederman may at some point in the future wish to dispose of some
  portion of his Class A Common Stock, which would cause all of the Class A
  Common Stock to be converted into Common Stock.  At such time as that might
  happen, the Company would become more vulnerable to certain tactics -- such as
  the accumulation of substantial voting positions as a prelude to an attempt to
  take over corporate control or effect significant corporate restructuring, a
  proxy fight, and other similar devices -- which have become relatively more
  common in recent years.  For the reasons discussed below, the Board of
  Directors considers that such tactics could be highly disruptive to a Company
  and can result in dissimilar and unfair treatment of a company's stockholders.
  Proposals No. 2 and 3 are being submitted for stockholder approval as a means
  of protecting the Company from these kinds of tactics and Proposal 4 is being
  submitted for that reason as well as to have authorized shares available for
  unrelated purposes.

     The Charter Amendments are interrelated but are being presented as three
  separate proposals.  The Charter Amendments are not being recommended in
  response to any past problems regarding Board of Director continuity or any
  specific effort of which the Board of Directors is aware to acquire control,
  but rather in anticipation of such activities which might result at such time
  as the Class A Common Stock is converted into Common Stock.

     If Proposal No. 2 is approved, because only one of the three classes of a
  classified Board will be elected annually, at least two annual stockholders'
  meetings, instead of one, will be required to effect a change in the control
  of the Board through the normal election processes.  The classified board
  amendment and related changes would require a person seeking to acquire
  control of the Company to wait up to two years to obtain control of the Board
  even though that person has acquired ownership of a majority or controlling
  minority interest in the Company.

                                       14
<PAGE>
 
     The classified board amendment and related changes would thus make it more
  difficult and time-consuming for any individual or entity who accumulates a
  substantial stock or voting position in the Company to obtain control of the
  Board or to effect change in the Company's day-to-day operations.  It would
  therefore reduce the vulnerability of the Company to takeover proposals that
  are not in the best interests of the Company or its stockholders.

     The classified board amendment and related changes, of course, would affect
  all stockholders, not just those seeking to acquire control of the Company, in
  the following ways:  (1) because at least two annual meetings will be required
  to change majority control on the Board, the amendment would tend to
  perpetuate present management; (2) forbidding removal of directors except for
  "cause" will make it more difficult to remove directors, even if removal were
  believed by a majority of the incumbent Board of Directors or stockholders to
  be in the Company's best interest, and (3) the amendment may tend to
  discourage accumulations of large blocks of stock by reducing the control
  effect of such blocks, thus reducing temporary fluctuations in market price
  that could be caused by such accumulations.

     Proposal No. 3 directs the Board of Directors to consider all relevant
  factors in connection with certain business combinations.  In the opinion of
  the Board of Directors, this provision will strengthen its position in dealing
  with anyone attempting to take over the Company.  The proposed amendment may
  discourage some potential purchasers from attempting any tender offer for the
  Company and may have significant effects on the ability of stockholders of the
  Company to benefit from certain transactions that are opposed by an incumbent
  Board of Directors.  This provision will tend to induce any persons seeking
  control of the Company or a business combination with the Company to negotiate
  on terms acceptable to the Board of Directors then in office.  It should be
  noted, however, that with respect to tender or exchange offers,
  recommendations of the Board of Directors are not binding on stockholders once
  the offer is made because these offers are made by the offeror to each
  stockholder individually.

     Proposal No. 3, if approved, may give comfort to the Company's employees,
  customers and other constituencies that the Board of Directors may consider
  their interests in deciding whether to recommend a tender or exchange offer or
  to authorize a merger.  The Board of Directors believes that this would have a
  positive impact on the communities in which the Company and its subsidiaries
  operate.  This proposal also reflects the Board of Directors' concern that the
  value of the Company may not be adequately reflected in the market price of
  its stock.  Therefore, this proposal would explicitly permit the Board of
  Directors to compare the consideration to be offered in a proposed acquisition
  of the Company with other measures of the Company's worth.

     Under certain circumstances, Proposal No. 3 may make it more difficult to
  impose legal liability on directors, or to set aside transactions by the
  Company, for example, when the director action in question is based on a
  determination that relevant non-financial factors outweigh the perceived
  immediate economic benefits of a transaction to the Company and its
  stockholders.

     If Proposal No. 4 increasing the authorized number of shares of Common
  Stock is adopted, the Company will have available additional shares for
  issuance for corporate purposes without the necessity of further stockholder
  approval.  Although the Company is not aware of any proposed 

                                       15

  takeover attempt, the ability of the Board of Directors to issue the newly-
  authorized but unissued shares of Common Stock might have the effect of
  discouraging an attempt by another person or entity to effect a takeover or
  otherwise gain control of the Company, since the issuance of additional shares
  of Common Stock would dilute the voting power of the Common Stock then
  outstanding. This could include issuances in private placements, in
  conjunction with the adoption of a stockholder rights plan, or otherwise, and
  in each case this could be accomplished without further stockholder approval.

     Advantages of Proposals

     The proposed Charter Amendments are intended to encourage persons seeking
  to acquire control of the Company to initiate such an acquisition through
  arm's length negotiations with the Company's Board.  If the Board is presented
  with a proposal from a third party who has acquired a substantial block of the
  Company's Common Stock, the Directors will be able to evaluate the proposal
  and study alternative proposals without the imminent threat of removal.  This
  will help ensure that the best price is obtained in any acquisition
  transaction that may ultimately be consummated.  Proposal No. 2 has the
  additional benefit of promoting continuity in leadership and policy on the
  Board and Proposal No. 4 provides additional authorized shares for general
  corporate purposes.

     Disadvantages of Proposals

     Adoption of the proposed Charter Amendments may deter certain mergers,
  tender offers, proxy contests or other future takeover attempts which holders
  of some or even a majority of the outstanding stock believe to be in their
  best interests, and may make removal of management more difficult even if such
  removal would be beneficial to stockholders generally.  Not all takeovers or
  changes in control of the Board that are proposed and effected without prior
  consultation and negotiation with the incumbent Board are necessarily
  detrimental to the Company and its stockholders.  However, the Board believes
  that the benefits of seeking to protect its ability to negotiate with the
  proponent of an unfriendly or unsolicited proposal to acquire or restructure
  the Company outweigh the disadvantages of discouraging such proposals.

     The provisions for electing only one out of three classes of the Board
  annually, rather than the entire Board, will be applicable to every annual
  election of directors, and not just to any election occurring after a change
  in stockholder control of the Company.  A classified Board could delay
  stockholders who do not like the policies of the Board of Directors from
  removing a majority of the Board for up to two years.  This would be so even
  if the only reason for the attempted action by a shareholder was
  dissatisfaction with the performance of the current Board.

     Relationship of Charter Amendments to Other Provisions

     The Company's Certificate of Incorporation presently contains two
  provisions and the By-Laws one which may have the effect of making a change of
  control more difficult.  Delaware law also contains an important limitation on
  changes in control.

                                       16

     Class A Common Stock.  The Company has outstanding 2,040,000 shares of
  Class A Common Stock, which are beneficially owned by Dr. David M. Lederman,
  founder of the Company, and Dr. Param I. Singh.  Each share of Class A Common
  Stock has ten votes per share upon all matters except the election of those
  directors (not less than 25% of the entire board) who are elected by holders
  of Common Stock, voting as a separate class.  As a result of the Class A
  Common Stock's greater voting power, Dr. Lederman has 57.1% and Dr. Singh
  24.6% of the total voting power of shares of all classes of capital stock at
  June 16, 1995, and thus control the Company.  However, as previously
  discussed, in general, a transfer of any Class A Common Stock by Dr. Lederman
  will cause all of the outstanding Class A Common Stock automatically to be
  converted into Common Stock, and a transfer by Dr. Singh will cause the shares
  transferred to convert into Common Stock but will not effect conversion of the
  remaining shares of Class A Common Stock outstanding.

     Preferred Stock.  The Company is authorized to issue up to 1,000,000 shares
  of Class B Preferred Stock, in one or more series, none of which have yet been
  issued.  The Board of Directors is authorized, without any further action by
  the stockholders, to determine the dividend rights, dividend rate, conversion
  rights, voting rights, rights and terms of redemption, liquidation
  preferences, sinking fund terms and other rights, preferences, privileges and
  restrictions of any series of Class B Preferred Stock, the number of shares
  constituting any such series and the designation thereof.  The Board of
  Directors may, without stockholder approval, issue Class B Preferred Stock
  with rights and privileges which could, among other things, have the effect of
  delaying, deferring or preventing a change in control of the Company.  The
  Company has no present plans to issue any shares of Class B Preferred Stock.

     Notice of Nomination.  At a meeting of the Board of Directors on June 15,
  1995, the Board of Directors voted to amend Section 2.3 of the Company's By-
  Laws to increase the number of days advance written notice of any stockholder
  nomination for director from not less than 14 nor more than 50 days to not
  less than 45 nor more than 60 days prior to the anticipated date of the annual
  meeting for election of directors.  The purpose of this amendment is to
  provide adequate advance notice to the Company concerning any proposed
  nominees.

     Delaware Statute.  Pursuant to Delaware law, Delaware corporations are
  prohibited from engaging in a wide range of specified transactions with any
  "interested stockholder", defined to include, among others, any person or
  entity who in the last three years obtained 15% or more of any class or series
  of stock entitled to vote generally in the election of directors, unless,
  among other exceptions, the transaction is approved by (i) the Board of
  Directors prior to the date the interested stockholder obtained such status or
  (ii) the holders of two-thirds of the outstanding shares of each class or
  series of stock entitled to vote generally in the election of directors, not
  including those shares owned by the interested stockholder.  By virtue of the
  Company's decision not to opt out of the provisions of this law, it applies to
  the Company.

     All of the various provisions described above, as well as Proposals No. 2-
  4, could be used by the Board of Directors in a manner calculated to prevent
  the removal of management and make more difficult or discourage a change in
  control of the Company.  Certain aspects of the foregoing provisions were
  designed to afford the Board of Directors the opportunity to evaluate the
  terms of a takeover attempt without haste or undue pressure, advise
  stockholders of its findings, and to negotiate to protect the interests of all
  stockholders.

     The Company is not aware of any efforts to accumulate the Company's
  securities or to obtain control of the Company, and the Company has no present
  intention or agreement to issue any additional shares of Common Stock, other
  than and pursuant to outstanding options and existing employee benefit and
  director option plans.


                                 PROPOSAL NO. 2
                   AMENDMENT TO CERTIFICATE OF INCORPORATION
                 TO PROVIDE FOR A CLASSIFIED BOARD OF DIRECTORS
                              AND RELATED MATTERS

     The Board of Directors unanimously recommends that stockholders approve the
  amendment of Section 4.2.2 of Article 4 and the addition of a new Article 13
  to the Certificate of Incorporation to (i) provide for the classification of
  the Company's Board of Directors into three classes, each comprising as nearly
  as possible one-third of the directors, (ii) restrict the ability of
  stockholders to enlarge the Board of Directors, (iii) provide that vacancies
  in the office of a director shall be in the first instance filled by the
  remaining directors, except in the case of the directors elected by the Common
  Stock voting as a separate class, (iv) provide that directors may only be
  removed "for cause" and only by the class or classes of stock which elected
  them, and (v) require an 80% affirmative vote of all votes entitled to be cast
  by holders of Common Stock and Class A Common Stock, voting as a single class,
  to amend, alter or repeal Section 4.2.2 or Article 13.  (See Exhibit A for the
  entire text of the proposed amendment.)

     Classified Board.

     At present, all the Company's directors are elected at each annual meeting
  of stockholders for a one year term.  If Proposal No. 2 is approved at the
  1995 Annual Meeting, the Class I directors would be elected for one year, the
  Class II directors for two years and the Class III directors for three years.
  At each annual meeting thereafter, the class of directors up for election
  would be elected for three years and the directors in the other two classes
  would continue in office.  The votes required for election would remain
  unchanged.  Under the Company's Certificate of Incorporation, the holders of
  the Company's Common Stock, voting separately as a class, are entitled to
  elect not less than 25% of the directors (presently two) to the Board of
  Directors and the balance of the directors are elected by the Common Stock and
  Class A Common Stock voting as a single class, with holders of Common Stock
  having one vote per share and holders of Class A Common Stock having ten votes
  per share.  The directors elected by holders of Common Stock voting as a
  separate class will be divided among the three classes of directors as evenly
  as is possible.  If the number of directors is changed, any newly-created
  directorships or decreases in directorships are to be assigned by the Board so
  as to make all classes as nearly equal in number as possible.

     Enlargement of Board of Directors, Filling of Vacancies and Removal of
  Directors.

     At the present time, while the Board of Directors has the right to fix the
  number of directors, under Section 2.6 of the Company's By-Laws, either the
  Board of Directors or the stockholders may 

                                       18
<PAGE>
 
  enlarge the Board. Under paragraph (a) of the proposed Article 13, the Board
  of Directors would have the exclusive power to fix the number of directors and
  to enlarge the Board.

     At the present time, Section 4.2.2(d) of Article 4 of the Certificate of
  Incorporation provides that vacancies in the office of a director elected by
  the holders of Common Stock voting as a separate class may be filled by the
  vote of such holders voting as a separate class, and that a vacancy in the
  office of a director elected by the holders of both classes of common stock
  voting as a single class may be filled by vote of the holders of both classes
  voting as a single class (with one vote per share of Common Stock and ten
  votes per share of Class A Common Stock).  In the absence of a stockholder
  vote, vacancies may be filled by the remaining directors elected by the same
  class or classes or, in the absence of any directors so elected, by all
  remaining directors.    Under the proposed amendments, Section 4.2.2(d) would
  provide that the power to fill vacancies in the Board of Directors would in
  the first instance be vested in the Board of Directors rather than
  stockholders, except that a vacancy in the office of director elected by the
  holders of Common Stock, voting as a separate class, would be filled by the
  holders of that class voting as a separate class.

     Section 4.2.2(c) presently provides that directors elected by the holders
  of the Common Stock voting as a separate class may be removed, with or without
  cause, by the holders of that class, that directors elected by both classes
  voting as a single class may be removed by the holders of both classes voting
  as a single class, with or without cause, and that, to the extent permitted by
  law, directors of any class can be removed by the Board of Directors for
  cause.  Under the proposed amendment to Section 4.2.2(c), directors would be
  removable only for cause and only by the stockholders of the class or classes
  of stock which were entitled to elect them.  The requirement for cause gives
  effect to the provisions of Delaware law that members of a classified board of
  Directors be removable only for cause unless the certificate of incorporation
  expressly provides otherwise.  The term "for cause" is not defined in the
  proposed amendment or by Delaware law, and no definitive meaning has been
  articulated by the courts.

     Increased Stockholder Vote for Amendment.

     Under Delaware law and the Company's Certificate of Incorporation,
  amendments to the Certificate require the affirmative vote of a majority of
  the votes entitled to be cast by holders of Class A Common  Stock and Common
  Stock outstanding and entitled to vote, voting as a single class (with holders
  of Common Stock having one vote per share and holders of Class A Common Stock
  having ten votes per share), and if the amendment would increase or decrease
  the aggregate number of authorized shares or adversely affect the powers,
  preferences or special rights of a class, than a majority of the outstanding
  shares of that class voting as a separate class.  However, Delaware law also
  permits provisions of a certificate of incorporation to require a greater vote
  than that otherwise required by law for any corporate action.

     As permitted by Delaware law, Proposal No. 2 requires the affirmative vote
  of at least eighty percent  (80%) of the votes entitled to be cast by the
  Common Stock and the Class A Common Stock (with holders of Common Stock having
  one vote per share and holders of Class A Common Stock having ten votes per
  share) for any further amendment, alteration or repeal of Secton 4.2.2 or
  Article 13 of the Certificate of Incorporation, in addition to any separate
  class vote which might be required by Delaware law.

                                       19
<PAGE>
 
     The 80% vote requirement will give the holders of a minority of the voting
  power a veto power over changes to Section 4.2.2 and Article 13, even if the
  holders of a majority of the voting power favored such changes.  However, this
  requirement would hinder attempts by a stockholder with a majority of the
  voting power to repeal those provisions to undermine the operation of the
  classified board.

     The proposed amendments are intended to moderate the pace of any change in
  the Board of Directors by extending the time required to replace a majority of
  the incumbent directors.  The Board of Directors believes that a classified
  Board would tend to assure desirable continuity in leadership and policy
  since, when the classified Board becomes fully operative, approximately two-
  thirds of the directors at any time will have had prior experience on the
  Board.  The Board of Directors does not believe that the Company has had any
  problems in the past with respect to continuity in leadership and policy.  The
  amendments may also impede assumption of the management of the Company by any
  other person or entity which, through a takeover bid or otherwise, might
  obtain a substantial number of shares of Common Stock.  For a discussion of
  possible adverse effects, see "Introduction to Charter Amendments."

     The Board of Directors has, subject to stockholder approval of Proposal 
  No. 2, amended the Company's By-Laws to conform to the provisions of Proposal
  No. 2.

     The affirmative vote of a majority of the votes entitled to be cast by
  holders of the Class A Common Stock and the Common Stock outstanding and
  entitled to vote, voting as a single class (with holders of Common Stock
  having one vote per share and holders of Class A Common Stock ten votes per
  share), is required for the adoption of Proposal No. 2.

     The Board of Directors unanimously recommends that the stockholders vote
  FOR approval of Proposal No. 2.


                                 PROPOSAL NO. 3
                   AMENDMENT TO CERTIFICATE OF INCORPORATION
             REGARDING THE CONSIDERATION OF ALL RELEVANT FACTORS IN
                 CONNECTION WITH CERTAIN BUSINESS COMBINATIONS

     The Board of Directors unanimously recommends that a new Article 14 be
  added to the Company's Articles of Incorporation in the form of Exhibit B
  hereto.  This provision would explicitly direct the Board of Directors to take
  into account all relevant of factors in exercising its business judgment in
  determining what is in the best interests of the Company and its stockholders
  in evaluating certain tender offers and business combination proposals.
  Neither the relative weight to be given each factor nor the method of
  determining how each factor is to be ascertained is specified in the
  amendment.  These are to be determined by the Board of Directors at the time
  of the exercise of its business judgment.

     This proposal, if approved, may give comfort to the Company's customers and
  other constituencies that the Board of Directors may consider their interests
  in deciding whether to 

                                       20
<PAGE>
 
  recommend a tender or exchange offer or to authorize a merger. The Board of
  Directors believes that this would have a positive impact on the communities
  in which the Company and its subsidiaries operate. This proposal also reflects
  the Board of Directors concern that the value of the Company may not be
  adequately reflected in the market price of its stock. Therefore, this
  proposal would explicitly permit the Board of Directors to compare the
  consideration to be offered in a proposed acquisition of the Company with
  other measures of the Company's worth.

     While the value of the consideration offered to the stockholders is a very
  important factor when weighing the benefits of a tender offer or other
  business combination proposal, the Board of Directors believes it also
  appropriate to consider other relevant factors.  For example, the proposed
  amendment directs the Board of Directors to evaluate the consideration being
  offered in relation to the then-current value of the Company in a freely
  negotiated transaction and in relation to the Board of Directors' estimate of
  the future value of the Company as an independent concern.  A takeover bid
  often places the target corporation virtually in the position of making a
  forced sale, sometimes when the market price of its stock may be temporarily
  depressed.  The Board of Directors believes that the consideration offered in
  such a situation, even though it  may be in excess of the then market price,
  is frequently less than that which could be obtained in a freely negotiated
  transaction.  On the other hand, in a freely negotiated transaction,
  management would have the opportunity to seek a suitable partner at a time of
  its choosing and to negotiate for the most favorable price and terms which
  reflect not only the current but also the future value of the Company.

     In recent years, a number of companies have adopted charter provisions
  similar to Proposal No. 3, and many states other than Delaware have enacted
  amendments to their corporation laws to accomplish a similar purpose.  Under
  present Delaware law, absent any charter provision like Proposal No. 3, the
  Board of Directors may be limited in its ability to consider any interests
  other than those of stockholders.  No Delaware case has yet evaluated the
  impact of a provision in the certificate of incorporation similar to Proposal
  No. 3 upon the decision-making processes of directors.

     Adoption of Proposal No. 3 will strengthen the hand of the Board of
  Directors in dealing with anyone attempting to take over the Company, but may
  also discourage potential purchases which may be advantageous to the Company.
  See "Introduction to Charter Amendments".

     The affirmative vote of a majority of the votes entitled to be cast by
  holders of the Class A Common Stock and Common Stock outstanding and entitled
  to vote, voting as a single class (with holders of Common Stock having one
  vote per share and holders of Class A Common Stock ten votes per share), is
  required for the adoption of Proposal No. 3.


     The Board of Directors unanimously recommends that the stockholders vote
  FOR approval of Proposal No. 3.

                                 PROPOSAL NO. 4

             AMENDMENT TO CERTIFICATE OF INCORPORATION TO INCREASE
                THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

     The Board of Directors unanimously recommends that the stockholders approve
  a proposal to amend the Company's Certificate of Incorporation to increase the
  number of authorized shares of Common Stock, $.01 par value, from 10,000,000
  to 25,000,000.  The additional shares of Common Stock would be part of the
  existing class of Common Stock and, if and when issued, would have the same
  rights and privileges as the shares of Common Stock presently outstanding.

     As of June 16, 1995, there were outstanding 4,885,821 shares of Common
  Stock.  In addition, an aggregate of 2,633,999 shares of Common Stock were
  reserved for issuance, 2,040,000 shares upon conversion of shares of Class A
  Common Stock, and 593,999 shares upon exercise of options outstanding or
  options available to be granted in the future under the Company's various
  stock option plans or under outstanding warrants.

     Pursuant to Delaware corporate law, the Board of Directors is authorized to
  issue from time to time any and all authorized and unissued shares of Common
  Stock for any proper corporate purposes without prior stockholder approval,
  except as may be required for a particular transaction by the Company's
  Certificate  of Incorporation, or by the rules of any stock exchange on which
  the Company's securities may then be listed.

     The Board of Directors believes that the proposed increase in the number of
  authorized shares of Common Stock is in the best interests of the Company and
  its stockholders.  While the Board of Directors has no specific plan for the
  issuance of additional shares of Common Stock, it believes that it is wise to
  increase the authorized number of shares at this time to give it the means and
  flexibility to take advantage of opportunities by allowing shares of Common
  Stock to be issued by the Board of Directors without the delay and expense of
  a special meeting of stockholders.  For example, the Board of Directors may
  deem it appropriate to make a private or public offering of the Company's
  Common Stock in order to raise funds for working capital or other purposes, or
  the Common Stock may be issued to finance possible future acquisitions, or for
  distribution to the Company's stockholders as a stock dividend or stock split,
  for distribution pursuant to employee benefit plans or to reserve such shares
  for issuance in conjunction with any future adoption of a stockholder rights
  plan.

     Stockholders of the Company do not now have preemptive rights to subscribe
  for or purchase additional shares of Common Stock, and the stockholders will
  have no preemptive rights to subscribe for or purchase any of the additional
  shares authorized by the proposed amendment.

     The affirmative vote by of a majority of the votes entitled to be cast by
  holders of the Class A Common Stock and Common Stock outstanding and entitled
  to vote, voting as a single class (with holders of Common Stock having one
  vote per share and holders of Class A Common Stock ten votes per share), and a
  majority of the votes of the Common Stock, voting as a separate class, is
  required for the adoption of Proposal No. 4.

                                 PROPOSAL NO. 5
              AMENDMENT OF THE 1992 COMBINATION STOCK OPTION PLAN

     The purpose of the 1992 Combination Stock Option Plan (the "1992 Plan") is
  to enable the Company to attract and retain the services of employees in a
  position to contribute to the long-term success and growth of the Company and
  its subsidiaries by providing them with long-term incentives.  On June 15,
  1995, the Board of Directors amended the 1992 Plan, subject to stockholder
  approval, to increase the number of shares of Common Stock authorized to be
  issued thereunder from 1,050,000 shares to 1,300,000 shares.

     The following is a summary of certain material features of the 1992 Plan.

     Stock Available for Options.  Under the 1992 Plan, an additional 250,000
  shares of Common Stock, for a total of 1,300,000 shares (including shares of
  Common Stock that were the subject of awards under the Company's predecessor
  ISO Plan and the Non-Qualified Plans which were superseded by the 1992 Plan)
  will be available for issuance.  As of June 16, 1995, a total of  732,971
  shares were available for issuance under the 1992 Plan, of which options to
  purchase 387,714 shares (net of cancellations) had been granted on that date.

     Administration.  The 1992 Plan is administered by the Compensation
  Committee, none of the members of which is eligible to participate in the 1992
  Plan while they are members and for a period of one year thereafter.  Subject
  to the 1992 Plan, the Compensation Committee determines persons to whom
  options are granted, the exercise price (for non-qualified stock options), the
  number of shares covered by any option, the term of any option and the time
  during which any option is exercisable.  The Compensation Committee also has
  the authority to adopt rules and make other determinations with respect to
  administration of the 1992 Plan.

     Eligibility.  Under the 1992 Plan, incentive stock options may only be
  granted to persons who are employees of the Company at the time of grant,
  which may include officers and directors (other than members of the
  Compensation Committee) who are also employees.  Non-qualified stock options
  may be granted to persons who are officers, directors or employees of, or
  consultants or advisors to, the Company at the time of grant, provided that
  directors who are not employees of the Company or who are members of the
  Compensation Committee are not eligible to participate in the 1992 Plan.

     Exercise Price.  Under the 1992 Plan, the purchase price of Common Stock
  subject to an incentive stock option may not be less than its fair market
  value of the date of grant or, in the case of persons owning stock possessing
  ten percent or more of the voting power of all outstanding capital stock of
  the Company on the date of grant, not less than 110% of the fair market value
  of the Common Stock on the date of grant.  To the extent that the aggregate
  fair market value of Common Stock (measured at the time of grant) with respect
  to which incentive stock options are first exercisable by an employee during
  any calendar year under the 1992 Plan and any other plan of the Company
  providing for incentive stock options exceeds $100,000, such incentive stock
  options shall be treated as options which are not incentive stock options.

                                       24
<PAGE>
 
     Under the 1992 Plan, the Compensation Committee has the authority to grant
  non-qualified stock options at any price not less than the par value ($0.1 per
  share) of the Common Stock.  To date all options granted by the Company have
  had an exercise price equal to their fair market value on the date of grant.
  The Company has no present plans to issue options to any person with an
  exercise price of less than the fair market value on the date of grant.

     Maximum Option Term.  Options granted under the 1992 Plan may not be
  exercised more than ten years from the date of grant, and in the case of
  incentive stock options issued to persons owning stock possessing ten percent
  or more of the voting power of all outstanding capital stock of the Company on
  the date of grant, more than five years from the date of grant.

     Exercise of Options.  The exercise price of options granted under the 1992
  Plan may be paid in cash with Common Stock (valued at fair market value on the
  date of purchase),  any other property (valued at fair market value on the
  date of purchase), or by a combination of cash, stock and other property as
  the Compensation Committee may permit.

     Exercise Restrictions.  No incentive stock option under the 1992 Plan may
  be exercised beyond three months after the option holder ceases to be an
  employee of the Company, except that the Compensation Committee is authorized
  to permit exercise for up to one year after termination of employment by
  reason of death or permanent and total disability.  No such restrictions apply
  for non-qualified stock options.  Options granted under the 1992 Plan may not
  be assigned or transferred except by will or the laws of descent and
  distribution.

     Amendment or Termination of 1992 Plan.  The 1992 Plan may be amended,
  suspended or terminated at any time by the Board of Directors, provided that
  any amendment to expand the definition of eligible participants, materially
  increase the benefits accruing to participants, increase the number of shares
  of  Common Stock reserved for issuance, extend the term, or otherwise modify
  the 1992 Plan in any way or manner requiring the approval of the stockholders
  under the Internal Revenue Code or Section 16 of the Securities Exchange Act
  of 1934, if applicable to the Company, will be subject to the approval of the
  Company's stockholders.

     Duration of 1992 Plan.  Options under the 1992 Plan may not be granted
  after May 1, 2002.

     Federal Tax Consequences.  The following discussion of the Federal income
  tax consequences of the issuance and exercise of options granted under the
  1992 Plan is based upon the provisions of the Internal Revenue Code as in
  effect on the date  of this proxy statement, current regulations thereunder,
  and existing administrative rulings of the Internal Revenue Service.  It is
  not intended to be a complete discussion of all of the Federal income tax
  consequences of the 1992 Plan or of the requirements that must be met in order
  to qualify for the described tax treatment.  The 1992 Plan is not qualified
  under Section 401 of the Internal Revenue Code and is not subject to the
  provisions of the Employee Retirement Income Security Act of 1974, as amended.

     Incentive Stock Options.
     ------------------------

     General Rules.  Incentive stock options granted under the 1992 Plan are
  intended to qualify as incentive stock options under Section 422 of the
  Internal Revenue Code.  An option holder generally 

                                       25
<PAGE>
 
  will not recognize taxable income upon either the grant or the exercise of an
  incentive stock option (However, under certain circumstances, there may be
  alternative minimum tax consequences on exercise, as discussed below.) An
  option holder will recognize taxable income upon the disposition of the shares
  received upon exercise of the option. In general, any gain recognized upon a
  disposition will be taxable as long-term capital gain. A different treatment
  applies to a "disqualifying disposition", as discussed below.

     Alternative Minimum Tax.  In general, for alternative minimum tax (or
  "AMT") purposes, an employee must include in alternative minimum taxable
  income, in the year of exercise of an incentive stock option, an amount equal
  to the excess of the fair market value of the shares issued upon exercise over
  the exercise price.  The AMT only applies if it produces a greater tax
  liability than the conventional tax system.

     Disqualifying Dispositions.  A "disqualifying disposition" means any
  disposition of shares acquired on the exercise of an incentive stock option
  within two years of the date the option was granted or within one year of the
  date the shares were transferred to the option holder.  In general, if an
  option holder makes a disqualifying disposition, a portion of the gain will be
  recognized as ordinary income.  Special rules apply to a disqualifying
  disposition by gift.

     Use of Already Owned Shares.  An option holder may pay the exercise price,
  in whole or in part, by delivering shares of Common Stock already owned by the
  holder.  In general he or she will recognize no gain or loss for Federal
  income tax purposes on the shares surrendered, but otherwise will be taxed
  according to the rules described above.  However, if the shares surrendered
  were acquired pursuant to an incentive stock option and the required holding
  periods have not been satisfied, then the rules regarding disqualifying
  dispositions, described above, will apply to the surrendered shares.

     Deduction to Company.  The Company will not be entitled to any deduction
  with respect to the grant or exercise of incentive stock options so long as
  the option holder does not make a disqualifying disposition.  If the option
  holder does make a disqualifying disposition, the Company will generally be
  entitled to a deduction for federal income tax purposes in an amount equal to
  the taxable income recognized by the option holder.

     The tax treatment of shares which may be forfeited if the recipient ceases
  being employed by the Company vary somewhat from the tax treatment described
  above.  Although the Company is permitted to issue options to purchase such
  shares, it has been the policy of the Company not to issue shares with a
  substantial risk of forfeiture.  Accordingly, a description of the tax
  treatment of such shares is not included in this proxy statement.

     Non-Qualified Stock Options.
     ----------------------------

     In General.  Non-qualified stock options granted under the 1992 Plan will
  not qualify as incentive stock options under Section 422 of the Internal
  Revenue Code.  The recipient of a non-qualified stock option under the 1992
  Plan will not recognize any taxable income at the time the option is granted.
  However, upon exercise, the option holder will generally recognize ordinary
  taxable income in an amount equal to the excess of the fair market value of
  the shares received on 

                                       26
<PAGE>
 
  the date of exercise over the option exercise price. Upon a subsequent sale of
  those shares, long-term or short-term gain or loss (depending upon the holding
  period) will generally be recognized equal to the difference between the
  amount realized and the fair market value of the shares on the date of
  exercise.

     Use of Already Owned Shares.  An option holder who pays the exercise price,
  in whole or in part, by delivering shares of Common Stock already owned by the
  holder will recognize no gain or loss for Federal income tax purposes on the
  shares surrendered, but otherwise will be taxed according to the rules
  described above.

     Deduction to Company.  When the option holder recognizes income, the
  Company is generally required to withhold income taxes with respect to that
  income.  If the Company satisfies its withholding obligations, the Company
  will generally be entitled to a compensation deduction for Federal income tax
  purposes in an amount equal to the taxable income recognized by the option
  holder.

     The affirmative vote of a majority of the votes of holders of the Class A
  Common Stock and the Common Stock (voting together as a single class, with the
  holders of Class A Common Stock having ten votes per share and the holders of
  Common Stock one vote per share) present in person or by proxy at the Meeting
  is required for adoption of Proposal No. 5.

     The Board of Directors recommends that stockholders vote FOR approval of
  Proposal No. 5.

                                       27

                                 PROPOSAL NO. 6
                      AMENDMENT TO THE 1989 NON-QUALIFIED
                  STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

     The purpose of the Company's 1989 Non-Qualified Stock Option Plan for Non-
  Employee Directors (the "Director Plan") is to attract and retain the services
  of experienced and knowledgeable non-employee directors for the benefit of the
  Company and its stockholders and to provide additional incentives for such
  independent directors to continue to work for the best interests of the
  Company and its stockholders through continuing ownership of is Common Stock.

     On June 15, 1995 the Board of Directors amended the Directors Plan, subject
  to stockholder approval, to increase the number of shares authorized to be
  issued under the plan from 150,000 shares to 200,000 shares.

     The following is a summary of the material features of the Directors Plan,
  as proposed to be amended.

     Stock Available for Options.  It is proposed to increase the number of
  shares of Common Stock which may be issued upon exercise of Options under the
  Directors Plan from 150,000 to 200,000.  Shares subject to an option that
  ceases to be exercisable for any reason are available for subsequent option
  grants.  Through June 15, 1995, options to purchase an aggregate of 95,000
  shares had been granted under the Directors Plan.

     Administration.  The Directors Plan is administered by the Board of
  Directors.  The Board of Directors is required to grant options under the
  Directors Plan as described below.  Its authority under the Directors Plan is
  otherwise limited  to adopting rules and regulations for the administration of
  the Directors Plan.  The Board of Directors is not liable for any act,
  omission, interpretation, construction or determination made in good faith in
  connection with its responsibilities under the Directors Plan.

     Eligibility.  Only directors of the Company who are not also employees of
  the Company and who do not own or are not affiliated with any person who owns,
  directly or indirectly, more than 5% of the vote of the Company's  outstanding
  voting stock are eligible to receive options under the Directors Plan (the
  'Eligible Directors").  Currently the Eligible Directors are Dr. Austen, Mr.
  Davis (who is not standing for reelection), Mr. Fireman, Mr. O'Brien and Mr.
  Termeer.   Mr. O'Connell will become an Eligible Director if he is elected at
  the Meeting.

     Grant and Vesting.  The Directors Plan provides that each newly elected
  Eligible Director will receive an option to purchase 12,500 shares upon being
  elected as a director.  Thereafter, each Eligible Director will be granted a
  new option to purchase 12,500 shares on July 1 of each successive fifth year.
  The options so granted vest over an approximately five year period at the rate
  of 2,500 shares per year, commencing on June 30 of the year following the date
  of grant.  No options were granted under the Directors Plan in the fiscal year
  ended March 31, 1995.  If Mr. O'Connell is elected as a director at the
  meeting, he will become an Eligible Director and will receive an option to
  purchase 12,500 shares under the Directors Plan.

                                       28
<PAGE>
 
     Exercise Price.  The purchase price of Common Stock subject to an option
  granted under the Directors Plan is the fair market value of the Common Stock
  on the date the option is granted, but in no event less than the par value of
  the shares.

     Exercise of Options.  The exercise price must be paid in full upon exercise
  of an option, and may be paid in cash, with Common Stock (valued at fair
  market value on the date of exercise) or any combination of cash and Common
  Stock.

     Rights in the Event of Termination, Death or Disability.  If an Eligible
  Director ceases to be a director, all options held be that person that are not
  then exercisable terminate.  Under the Directors Plan, options that are
  exercisable at the time the Eligible Director ceases to be a director will
  remain exercisable until the earlier to occur of one year following such
  termination or ten years after the date the option is granted.

     Transfer Restrictions.  An option is exercisable only by the option holder
  during the holder's lifetime, and no option or right or interest in an option
  is assignable or transferable by the holder except by will or the laws of
  descent and distribution.

     Amendment or Termination of Directors Plan.  The Board of Directors may, at
  an time, amend, suspend or terminate the Directors Plan.  Any such amendment
  which materially increases the number of shares which may be subject to
  options granted under the Directors Plan, the benefits accruing to
  participants in the Directors Plan, or the requirements for eligibility to
  participate in the Directors Plan, is subject to stockholder approval.
  Furthermore, the Board of Directors may not amend the Directors Plan more
  often than once every six months to change the amount and price of securities
  to be awarded and the timing of such awards, other than to comport with
  changes in the Internal Revenue Code and the Employee Retirement Income
  Security Act of 1974.  (Under current law, the Directors Plan is not qualified
  under Section 401 of the Internal Revenue Code and is not subject to the
  provisions of the Employee Retirement Income Security Act of 1974, as
  amended.)  No amendment, suspension or termination of the Directors Plan may
  adversely affect the rights of an option holder without the holder's consent.

     Duration of the Directors Plan.  The Directors Plan may be discontinued at
  any time by the Board of Directors.  If not earlier discontinued, it will
  terminate on July 10, 1999.  No option may be granted under the Directors Plan
  after the date of termination.  Termination will not affect the validity of
  options granted prior to the date of termination.

     Federal Tax Consequences of the Directors Plan.  In general, the tax
  treatment of options offered under the Directors Plan is the same as the
  treatment of non-qualified options offered under the 1992 Plan.  Thus, a
  recipient of an option under the Directors Plan will not recognize any taxable
  income at the time the option is granted.

     Tax Treatment of Exercise and Effect of Section 16(b).  The tax treatment
  of the exercise of an option under the Directors Plan is somewhat different
  than the treatment described under the 1992 Plan.  This is because Eligible
  Directors under the Directors Plan generally will be subject to Section 16(b)
  of the Securities Exchange Act of 1934 ("Section 16(b)") upon their sale of
  shares of Common Stock.  The Internal Revenue Code provides that in the case
  of exercise of an option by someone 

                                       29
<PAGE>
 
  whose sale of Common Stock would subject the holder to liability under Section
  16(b), recognition of income by the option holder will be postponed. The
  Internal Revenue Service regulations have not yet been amended to conform with
  the revised rules under Section 16(b). However, it is generally anticipated
  that the recognition date will be the earlier of (i) the date six months after
  the date the option was granted or (ii) the first day on which the sale of the
  shares would not subject the option holder to liability under Section 16(b).
  (It is possible that the six month period will instead run from the option
  holder's most recent purchase of Common Stock prior to his or her exercise of
  the option.) At that time, the option holder will generally recognize ordinary
  taxable income in an amount equal to the excess of the then fair market value
  of the shares of Common Stock over the Exercise Price. However, if that date
  is after the date of exercise, the option holder may make an election pursuant
  to Section 83(b) of the Internal Revenue Code within 30 days after exercise,
  in which case the option holder will recognize ordinary taxable income at the
  time the option is exercised and not on the later date.

     Use of Already Owned Shares.  The tax treatment of purchase of shares with
  already owned shares is the same as described above for non-qualified stock
  options under the 1992 Plan.

     Deduction to Company.  The Company generally will be entitled to a
  compensation deduction for Federal income tax purposes at the same time as,
  and in the same amount that, the option holder recognizes ordinary taxable
  income, provided that the Company satisfies its withholding obligations.

     Tax Treatment of Sales of Shares.  The tax treatment of the sale of shares
  acquired pursuant to the Directors Plan is generally the same as the treatment
  of non-qualified shares under the 1992 Plan, discussed above.  However, the
  holding period for these shares will begin when the Section 16(b) restriction
  lapses, or when the holder acquires the shares if an election pursuant to
  Section 83(b) is made.

     The affirmative vote of a majority of the votes of holders of Class A
  Common Stock and Common Stock (voting together as a single class, with the
  holders of Class A Common Stock having ten votes per share and the holders of
  Common Stock having one vote per share) present in person or by proxy at the
  Meeting is required for adoption of Proposal No. 6.

     The Board of Directors recommends that stockholders vote FOR approval of
  Proposal No. 6.

  OTHER MATTERS

  Independent Public Accountants

     The Board of Directors has appointed Arthur Andersen LLP., as the
  independent certified public accountants to audit the consolidated financial
  statements of the Company for the fiscal year ending March 31, 1996.  That
  firm has served as the Company's auditors since 1983.

     A representative of Arthur Andersen LLP. will be at the Meeting and will be
  given an opportunity to make a statement, if so desired.  The representative
  will be available to respond to appropriate questions.

  Reporting Under Section 16(a) of the Securities and Exchange Act of 1934

     Section 16(a) of the Securities and Exchange Act of 1934 requires the
  Company's executive officers and directors, and persons who own more than 10%
  of the Company's Common Stock, to file reports of ownership and changes of
  ownership on Forms 3, 4 and 5 with the Securities and Exchange Commission and
  NASDAQ, and furnish the Company with copies of such Forms.

     Based solely on the Company's review of the copies of such Forms it has
  received and written representations from certain reporting persons that they
  were not required to file Forms 5 with respect to the Company's most recent
  fiscal year, the Company believes that all of its current executive officers,
  directors and greater than 10% stockholders complied with all Section 16(a)
  filing requirements applicable to them during the Company's fiscal year ended
  March 31, 1995.

  Other Proposed Action

     The Board of Directors knows of no other business to come before the
  Meeting.  However, if any other business should properly be presented to the
  Meeting, the proxies will be voted in accordance with the judgment of the
  person or persons holding the proxies.

  Stockholder Proposals

     Proposals which stockholders intend to present at the Company's 1996 Annual
  Meeting of Stockholders and wish to have included in the Company's proxy
  materials must be received by the Company no later than March 2, 1996.

  Incorporation by Reference

     To the extent that this Proxy Statement has been or will be specifically
  incorporated by reference into any filing by the Company under the Securities
  Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended,
  the sections of the Proxy Statement entitled "Compensation Committee Report on
  Executive Compensation" and "Performance Graph" shall not be deemed to be so
  incorporated, unless specifically otherwise provided in any such filing.

                                   ---------

  1.  Paragraphs (c) and (d) and (g) of Section 4.2.2 of Article 4 would be
      amended so that Section 4.2.2 as amended would read in its entirety as
      follows:

      4.2.2 Voting Rights and Powers.
            ------------------------ 

      (a)   Except as specified hereafter, and except as otherwise required by
            law with respect to all matters upon which stockholders are entitled
            to vote or give consent, the holders of the outstanding shares of
            the Common Stock and the holders of the outstanding shares of the
            Class A Common Stock shall vote together as a single class, and
            every holder of the outstanding shares of the Common Stock shall be
            entitled to cast thereon one (1) vote in person or by proxy for each
            share of the Common Stock standing in his or her name, and every
            holder of outstanding shares of the Class A Common Stock shall be
            entitled to cast thereon ten (10) votes in person or by proxy for
            each share of Class A Common Stock standing in his or her name.

      (b)   Subject to paragraph (f) below, the holders of the Common Stock,
            voting as a separate class, shall be entitled to elect that number
            of directors which constitutes 25% of the total number of the
            directors, and if such 25% is not a whole number, then the holders
            of Common Stock will be entitled to elect the nearest higher whole
            number of directors which constitutes 25% of such membership. The
            remaining directors will be elected in accordance with paragraph
            (a).

      (c)   Any director elected by the holders of Common Stock voting as a
            separate class under paragraph (b) above may only be removed for
            cause by the holders of the Common Stock voting as a separate class.
            The remaining directors may be removed only for cause by the
            stockholders voting in accordance with paragraph (a).

      (d)   So long as there is any Class A Common Stock outstanding, any
            vacancy in the office of a director electable by the holders of
            Common Stock voting as a separate class may be filled by a vote of
            such holders voting as a separate class, and in the absence of such
            a stockholder vote, such vacancy may be filled by the remaining
            directors elected by the Common Stock voting as a separate class,
            and in the absence of any directors so elected, by all the remaining
            directors. So long as there is any Class A Common Stock outstanding,
            any vacancy in the office of a director electable by the holders of
            both classes of common stock voting as a single class shall be
            filled by the remaining directors elected by both classes, and in
            the absence of any directors so elected, by the holders of both
            classes of common stock voting as a single class. At such time as
            there is no longer any Class A Common Stock outstanding, any vacancy
            in the office of director shall be filled by the remaining
            directors, and in the absence of any directors, by the stockholders.
            Unless the conditions set forth in paragraph (f) exist in respect of
            the next annual meeting of stockholders, the Board of Directors may
            be enlarged by the Board of Directors only to the extent that 
            twenty-five percent (25%) of the enlarged Board of Directors
            consists of directors either (i) elected by the holders of the
            Common Stock or (ii) appointed by

                                       33
<PAGE>
 
            directors elected by the holders of Common Stock voting as a
            separate class.

      (e)   The holders of Common Stock shall be entitled to vote as a separate
            class on such other matters as may be required by law to be voted
            upon by them as a separate class.

      (f)   The holders of the Common Stock shall not be entitled to separately
            vote as set forth in paragraphs (b)-(d) above if on the date for
            taking a record for any stockholder meeting at which directors are
            to be elected, the number of issued and outstanding shares of Common
            Stock (exclusive of any shares held in the corporation's treasury)
            is less than ten percent (10%) of the aggregate number of issued and
            outstanding shares of both Common Stock and Class A Common Stock
            (exclusive of shares held in the corporation's treasury). In such
            case, all directors to be elected shall be elected by holders of
            Common Stock and Class A Common Stock voting together as a single
            class in accordance with paragraph (a) above.

      (g)   This Certificate of Incorporation may be amended to change the
            powers, preferences, relative voting power or special rights of the
            shares of the Common Stock or the Class A Common Stock so as to
            affect either class adversely relative to the other, but any
            proposal to do so shall require the approval of a majority of the
            votes entitled to be cast by the holders of the class adversely
            affected by the proposed amendment, voting separately as a class, in
            addition to the approval of a majority of the votes entitled to be
            cast by the holders of the Common Stock and the Class A Common Stock
            voting together as a single class as hereinbefore provided. In
            addition, this Section 4.2.2 shall not be amended, altered or
            repealed except by the affirmative vote of eighty percent (80%) of
            the votes entitled to be cast by the stockholders voting in
            accordance with paragraph (a).

  2.  Article 13 would be added to read in its entirety as follows:

     13.  CLASSIFIED BOARD OF DIRECTORS
          -----------------------------

     (a)  The number of directors of the corporation shall be the number, not
          less than 3 nor more than 12, fixed from time to time by the Board of
          Directors.  The Board of Directors may be enlarged only by vote of a
          majority of the directors then in office.

     (b)  Commencing at the annual meeting of the stockholders in 1995, the
          directors shall be divided into three classes, designated Class I,
          Class II and Class III.  Each class shall consist, as nearly as may be
          possible, of one third of the number of directors constituting the
          entire Board of Directors.  At the annual meeting of the stockholders
          held in 1995, Class I directors shall be elected for a one year term,
          Class II directors shall be elected for a two year term, and Class III
          directors shall be elected for a three year term, and in each case
          until their successors are duly elected and qualified.  Commencing in
          1996, at each annual meeting of the stockholders successors to the
          class of directors whose terms expire at that annual meeting of
          stockholders shall be elected by stockholders for a three year term
          and until their successors are duly elected and qualified.  If the
          number of directors constituting the entire Board of Directors shall
          be changed as provided in paragraph (a) of this Article 13, the
          increase or decrease shall be apportioned among 

                                       34
<PAGE>
 
          the classes so as to maintain the number of directors in each class as
          nearly equal as possible.

     (c)  Any director elected to fill a vacancy resulting from an increase in
          any class or from the removal from office, death, disability,
          resignation or disqualification of a director or other cause shall
          hold office for the remaining term of the class to which such director
          is elected.  No decrease in the size of the Board of Directors shall
          have the effect of removing or shortening the term of any incumbent

  14. CONSIDERATION OF RELEVANT FACTORS IN BUSINESS COMBINATIONS.
      ---------------------------------------------------------- 

     The Board of Directors of the corporation, when evaluating any offer of
     another party to (i) purchase or exchange any securities or property for
     any outstanding equity securities of the corporation, (ii) merge or
     consolidate the corporation with another corporation, or (iii) purchase or
     otherwise acquire all or substantially all of the properties and assets of
     the corporation, shall, in connection with the exercise of its judgment in
     determining what is in the best interests of the corporation and its
     stockholders, give due consideration to all relevant factors, including
     without limitation:  (a) not only to the price or other consideration being
     offered in relation to the then current market price of the corporation's
     outstanding shares of capital stock, but also the Board of Directors
     estimate of the future value of the corporation as an independent going
     concern and the unrealized value of its property and assets;  (b) the
     financial and managerial resources and future prospects of the other party;
     and  (c) the possible social, legal, environmental and economic effects of
     the transaction on the business of the corporation and its subsidiaries and
     on the employees, customers, suppliers and creditors of the corporation and
     its subsidiaries and the effects on the communities in which the
     corporation's facilities are located.  In evaluating any such offer on the
     basis of the foregoing factors, the directors shall be deemed to be
     performing their duly authorized duties and acting in good faith and in the
     best interests of the corporation within the meaning of Section 145 of the
     General Corporation Law of Delaware, as it may be amended from time to
     time.
