                       PROXY STATEMENT FOR ANNUAL MEETING
                                OF STOCKHOLDERS
 
                                AUGUST 11, 1997
 
     This proxy statement is being furnished to the holders of the Common Stock,
par value $.001 per share (the "Common Stock"), of Black Box Corporation, a
Delaware corporation (the "Company"), in connection with the solicitation by the
Board of Directors of the Company (the "Board of Directors" or the "Board") of
proxies to be voted at the annual meeting of stockholders (the "Annual Meeting")
scheduled to be held on Monday, August 11, 1997, at 11:00 a.m., at the offices
of Buchanan Ingersoll Professional Corporation, One Oxford Centre, 301 Grant
Street, 20th Floor, Pittsburgh, Pennsylvania 15219, or at any adjournment
thereof. This proxy statement and form of proxy was first mailed to stockholders
on or about July 1, 1997. A copy of the Company's Annual Report to Stockholders
for the year ended March 31, 1997 is being furnished with this proxy statement.
 
     Only holders of the Common Stock of record as of the close of business on
Friday, June 20, 1997 are entitled to notice of and to vote at the Annual
Meeting and any adjournment thereof. On that date,           shares of Common
Stock, each entitled to one vote per share, were outstanding.
 
     All shares of Common Stock represented by valid proxies received by the
Secretary of the Company prior to the Annual Meeting will be voted as specified
in the proxy. If no specification is made, the shares will be voted FOR the
election of each of the Board's nominees to the Board of Directors and each of
the matters submitted by the Board of Directors for vote by the stockholders.
Unless otherwise indicated by the stockholder, the proxy card also confers
discretionary authority on the Board-appointed proxies to vote the shares
represented by the proxy on any matter that is properly presented for action at
the Annual Meeting. A stockholder giving a proxy has the power to revoke it any
time prior to its exercise by delivering to the Secretary of the Company a
written revocation or a duly executed proxy bearing a later date (though no
revocation shall be effective until notice thereof has been given to the
Secretary of the Company), or by attendance at the meeting and voting his or her
shares in person.
 
     Under the Company's Second Restated Certificate of Incorporation, as
amended (the "Certificate of Incorporation"), and Restated By-Laws, as amended
(the "By-Laws"), and applicable state law, abstentions and broker non-votes
(which arise from proxies delivered by brokers and others, where the record
holder has not received direction on voting and does not have discretionary
authority to vote on one or more matters) are each included in the determination
of the number of shares present. Abstentions and broker non-votes, if any, are
tabulated on the proposals presented to stockholders. Abstentions and broker
non-votes will have no effect against the proposals presented in this Proxy
Statement, except with respect to the proposed amendment to the Company's
Certificate of Incorporation which requires the affirmative vote of a majority
of the outstanding shares of Common Stock.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR EACH OF THE
NOMINEES NAMED BELOW FOR ELECTION AS DIRECTOR, FOR APPROVAL OF AN INCREASE IN
THE NUMBER OF SHARES FOR WHICH OPTIONS MAY BE GRANTED UNDER THE 1992 STOCK
OPTION PLAN FROM 2,450,000 TO 3,200,000, FOR APPROVAL OF AN INCREASE IN THE
NUMBER OF AUTHORIZED SHARES OF COMMON STOCK FROM 20,000,000 TO 40,000,000 (THE
"CERTIFICATE AMENDMENT") AND FOR THE RATIFICATION OF THE APPOINTMENT OF ARTHUR
ANDERSEN LLP AS THE INDEPENDENT PUBLIC ACCOUNTANTS OF THE COMPANY FOR THE FISCAL
YEAR ENDING MARCH 31, 1998.
<PAGE>   4
 
PROPOSAL 1
                             ELECTION OF DIRECTORS
 
     The Company's By-Laws provide that the number of directors constituting the
entire Board shall be nine (9), or such other number as shall be fixed by the
stockholders or by the Board of Directors. At present, the Board has fixed the
number of directors at eight (8) members, but the number of directors will
decrease to seven (7) members effective as of the date of the Annual Meeting.
 
     All directors of the Company are elected each year. Therefore, seven (7)
directors are to be elected at the Annual Meeting to hold office for a term of
one (1) year and until their respective successors are elected and qualified,
subject to the right of the stockholders to remove any director as provided in
the By-Laws. Any vacancy in the office of a director may be filled by the
stockholders. In the absence of a stockholder vote, a vacancy in the office of a
director may be filled by the remaining directors then in office, even if less
than a quorum, or by the sole remaining director. Any director elected by the
Board of Directors to fill a vacancy shall serve until his successor is elected
and has qualified or until his or her earlier death, resignation or removal. If
the Board of Directors increases the number of directors, any vacancy so created
may be filled by the Board of Directors.
 
     The holders of Common Stock have one vote for each share owned as of the
record date in the election of directors. The seven (7) nominees receiving the
greatest number of affirmative votes will be elected as directors for terms
expiring in 1998.
 
     The persons named as proxies on the enclosed proxy card were selected by
the Board of Directors and have advised the Board of Directors that, unless
authority is withheld, they intend to vote the shares represented by them at the
Annual Meeting for the election of William F. Andrews, Michael E. Barker,
Jeffery M. Boetticher, William R. Newlin, William Norred, Brian D. Young and
Fred C. Young, nominees of the Board of Directors, each of whom presently serves
as a director of the Company.
 
     The Board of Directors knows of no reason why any nominee for director
would be unable to serve as director. If at the time of the Annual Meeting any
of the named nominees is unable or unwilling to serve as a director of the
Company, the persons named as proxies intend to vote for such substitute as may
be nominated by the Board of Directors.
 
     The following sets forth certain information concerning the Company's
nominees for election to the Board of Directors at the Annual Meeting.

(1) Payment of the incentive plan is based on the Company meeting or exceeding
    cumulative three-year targets for both revenue and earnings before interest,
    taxes and amortization ("EBITA"). The three-year period covers fiscal 1996,
    1997 and 1998. If the targets are achieved, lump-sum cash payments are to be
    made following the completion of the fiscal 1998 audit and within the first
    45 days of fiscal 1999.
 
(2) The incentive plan specifies a fixed lump-sum if the established targets are
    achieved.
 
(3) Mr. Ejrup resigned his position at the Company in January 1997 and hence
    under the terms of the plan is only eligible for one-third of the incentive
    payout.
 
           REPORT OF THE COMPENSATION COMMITTEE AND OPTION COMMITTEE
 
     The Compensation Committee of the Board of Directors is charged with
administering the Company's compensation programs for executive officers,
including basic compensation and incentive compensation plans. The Option
Committee of the Board of Directors is charged with administering the Company's
stock option plans, including the Employee Plan. The Company believes that its
total executive compensation package should be designed to facilitate the
achievement of short- and long-range Company goals, to recognize individual
executive performance and contribution, and to promote increased value creation
for the Company's stockholders. To this end, the Company, the Compensation
Committee and the Option Committee seek to:
 
                                        6
<PAGE>   9
 
     - Hire, train, develop, compensate and retain the highest quality
       executives possible for the Company's success.
 
     - Reward executives for outstanding contributions to the achievement of the
       Company's goals and overall success.
 
     - Provide incentives for executives to align their goals with those of the
       stockholders through pay-for-performance and growth-driven compensation
       in the form of cash compensation and stock option plans.
 
BASIC COMPENSATION
 
     Basic compensation for executives is paid based upon performance,
experience, the requirements of the position and the executive's relative
ability to impact the Company's overall growth and success. The Company and the
Compensation Committee believe that the basic compensation paid to the Company's
executives is competitive with that paid to executives in other direct marketing
and computer companies. The cash compensation paid during fiscal 1997 to the
Company's executives as a group is in the middle range compared with that of
such peer group. Historically, in making compensation decisions the Company has
relied upon its Board of Directors and the Compensation Committee regarding
their collective knowledge of the industry, the functions that Company
executives perform and comparative salaries. Salaries and bonuses for fiscal
1997 were set in February 1996.
 
     The primary goals for executives, in their own respective positions, are to
help the Company achieve its yearly sales, profit and growth targets as
established by the Board of Directors. Salaries for the executives are reviewed
by the Compensation Committee on an annual basis and may be increased or
decreased based upon the Compensation Committee's decision that they are
competitive in the industry, and/or that a particular executive's contributions
to the Company have been significant during the year.
 
     As a group, the Company's executives received salary increases averaging 8%
for fiscal 1997.
 
INCENTIVE COMPENSATION PLANS
 
     The Company has a variable compensation plan covering all employees,
including executive officers. This plan provides for the payment of a bonus to
participants, equal to a percentage of base salary, in the event that certain
annual performance targets for revenue and operating profits are achieved. Any
payments under this plan are subject to approval by the Board of Directors on an
annual basis. Payments made to the Company's Named Executive Officers in fiscal
1997 under this plan are set forth in the Summary Compensation Table under the
caption "Annual Compensation--Bonus."
 
     The Company has a long-term incentive compensation plan covering fiscal
1996, 1997 and 1998 and is payable following the completion of the fiscal 1998
audit and within the first 45 days of fiscal 1999, if the three-year targets are
achieved. See "Executive Compensation and Other Information--Long-Term Incentive
Plan Awards in Last Fiscal Year."
 
     The Company's incentive compensation plans are predicated on the Company's
belief that executives contribute to stockholder returns by increasing the
Company's stock price, maximizing earnings and profit, and providing for
long-term growth.
 
STOCK OPTION PLAN
 
     In fiscal 1993, the Company's Board of Directors and stockholders approved
the Employee Plan, pursuant to which stock options may be granted by the Option
Committee to key employees, including those who may be executive officers of the
Company. This plan was amended in fiscal 1995, fiscal 1996 and fiscal 1997
pursuant to a vote of stockholders to increase the number of shares available
for the grant of options thereunder. Information with respect to the options
granted to the Named Executive Officers in fiscal 1997 is set forth in the table
entitled "Option Grants in Last Fiscal Year" appearing elsewhere in this proxy
statement.
 
                                        7
<PAGE>   10
 
The Option Committee believes that the options granted are consistent with the
Company's overall compensation policies and the individual compensation packages
of each Named Executive Officer.
 
     Historically the Company has issued Non-Qualified Stock Options at the fair
market value on the date of grant. The Option Committee's anticipates continuing
this practice in the future.
 
CHIEF EXECUTIVE OFFICER'S COMPENSATION ANALYSIS
 
     In determining the total compensation for the Chief Executive Officer, the
Compensation Committee used the same criteria described above in the opening
paragraphs of this section and the Basic Compensation section. In addition, the
Committee considered the Company's performance against goals established by the
Board of Directors at the beginning of the year.
 
     The Compensation and Option Committees believe that the increase in base
salary and grants of options to the Chief Executive Officer were appropriate for
fiscal 1997 because of the performance of the Company, the individual
performance of Mr. Boetticher, general executive compensation trends and the
overall business environment.
 
SUMMARY
 
     In the aggregate, an average of 60% of the Company's Named Executive
Officers' cash compensation for fiscal 1997 came from incentives directly
related to Company performance. The Company believes that the compensation paid
to its executives for fiscal 1997 was reasonable in view of the Company's
performance and the contributions of those executives to that performance, as
well as the comparison of their compensation with that of other companies in the
peer group listed in the performance graph.

     The above graph represents and compares the value, through March 31, 1997,
of a hypothetical investment of $100 made on June 6, 1994, the date of the
spin-off of MICOM, in each of (i) the Company's Common Stock, (ii) the Nasdaq
Market Index, and (iii) the companies comprising the Peer Group, assuming, in
each case, the reinvestment of dividends. The cumulative stockholder return
through March 31, 1997 indicates that the Company has out performed its Peer
Group and the Nasdaq Market Value Index.
 
     The Company believes any comparisons of the price of the Company's Common
Stock before June 6, 1994, would not be useful to stockholders since the value
of the Company's Common Stock prior to that date included the value of MICOM,
which was spun off at that time. On June 3, 1994, the date on which the spin-off
was consummated, the closing price of the post-spin-off Company Common Stock was
$12.00. On June 6, 1994, the last trading day prior to the consummation of the
spin-off, the closing price of historical combined common stock was $21.25.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     In fiscal 1997, the Compensation Committee of the Board of Directors
consisted of Mr. Barker, as Chairman, and Messrs. Fisher and Norred and the
Option Committee of the Board of Directors consisted of Mr. Brian D. Young, as
Chairman, and Mr. Andrews.
 
     In May 1997, the Board transferred the functions of the Option Committee to
the Compensation Committee and terminated the Option Committee. The Compensation
Committee will consist of Mr. Brian D. Young, as Chairman and Messers Barker,
Newlin, Norred and Andrews.
 
     Mr. Barker was formerly Chairman of the Board of the Company from March
1991 until November 1995, although he received no compensation from the Company
for serving in such capacity; however, he did receive certain fees under a
services agreement with Odyssey Investors, Inc. This services agreement provided
for the provision of consulting and advisory services by Odyssey Investors, Inc.
for an annual fee of $150,000. Beginning January 1, 1995, one-half of this fee
was paid to Odyssey Investors and one-half to Mr. Barker, a former principal of
Odyssey Partners which is affiliated with Odyssey Investors, Inc. In fiscal 1996
and fiscal 1995 Mr. Barker received $65,250 and $18,750, respectively. This
services agreement expired in December 1995.
 
     Mr. Barker was formerly the President of the Company until June 3, 1994
preceded by Mr. Brian Young as President from February 1989 until January 1992.
 
     In October 1994, Mr. Barker entered into a Quotaholder Agreement with Black
Box do Brazil Industria e Comercio Ltda. ("Black Box Brazil"), a subsidiary of
the Company (the "Quotaholder Agreement"). The Quotaholder Agreement provided
for Mr. Barker to receive 27,000 quotas (the equivalent of shares), or 15%
equity ownership, in Black Box Brazil in return for providing managerial
expertise to Black Box Brazil. Under the Quotaholder Agreement, the Company has
the option to purchase Mr. Barker's (and another party's) quotas after three
years and is obligated to purchase such quotas after five years based upon a
predetermined formula. The Quotaholder Agreement further provides for
pre-emptive rights in the event that additional quotas are issued, and restricts
Mr. Barker from competing with Black Box Brazil for a period of two years after
having had any affiliation with Black Box Brazil.
 
     Mr. Norred founded MICOM Systems, Inc., the predecessor of the Company, and
served as its President and Chief Executive Officer until December 1987.
 
CHANGE OF CONTROL AGREEMENTS
 
     The Company has change of control agreements with Jeffery M. Boetticher,
Chairman of the Board and Chief Executive Officer, and Fred C. Young, President,
Chief Operating Officer, Secretary and Treasurer. The purpose of these
agreements is to encourage these executives to remain with the Company, and
thereby assure the Company of the continued availability of their services and
their advice, in the event of an attempted change in control of the Company.
Each of these agreements is for a five-year term and becomes operative only upon
a "change in control" of the Company, as defined in the agreements. If, within
the term of the agreement and after a change of control, the executive's
employment is terminated by the Company other than for cause or is terminated by
the executive for "good reason" (such as a reduction in salary or benefits or
diminution in duties), the executive will be entitled to a lump sum payment of
generally up to three times the sum of his base salary (as defined) plus the
average cash award received by him under the Company's incentive compensation or
bonus plan for the prior two years. The Company is also required to maintain the
executive's other benefits (life insurance, health insurance, etc.) through the
unexpired term of the agreement. The agreement also provides for the immediate
vesting of any outstanding stock appreciation rights or options. The executive
may terminate his employment without cause, in which case the executive is not
entitled to receive further salary and benefits under the agreement. In
addition, the Company may terminate the executive for "cause" (as defined), at
which time all salary and other benefits to the executive would cease.

PROPOSAL 2
 
          APPROVAL OF AMENDMENTS TO COMPANY EMPLOYEE STOCK OPTION PLAN
 
     In November 1992, the Board of Directors and stockholders adopted the
Employee Plan. The Employee Plan authorized the issuance of options and stock
appreciation rights covering up to 1,000,000 shares of Common Stock (subject to
appropriate adjustments in the event of stock-splits, stock dividends and
similar dilutive events). In August 1994, the Board of Directors adopted and the
stockholders approved an increase in the number of shares available for the
grant of options under the Plan from 1,000,000 to 1,600,000. In August 1995, the
Board of Directors adopted and the stockholders approved an increase in the
number of shares available for the grant of options under the Plan from
1,600,000 to 2,200,000. In August 1996, the Board of Directors adopted and the
stockholders approved an increase in the number of shares available for the
grant of options under the Plan from 2,200,000 to 2,450,000. The Employee Plan
constitutes a key element of the Company's incentive program and is utilized to
attract, retain and motivate key employees of the Company and to align key
employee and stockholder interests.
 
     As a result of the prior grant of stock options under the Employee Plan,
the number of shares available for grant of stock options or stock appreciation
rights as of May 20, 1997 is 40,305 shares. The Board of Directors has
determined that this amount is insufficient to continue to maintain the
Company's needs under its incentive program. As a result, the Board has adopted
and proposes that the stockholders approve an amendment to the Employee Plan
which will increase the total number of shares available for the grant of stock
options under the Employee Plan by 750,000 shares, thereby increasing the
aggregate number of shares which would be available for the grant of options or
stock appreciation rights from 2,450,000 to 3,200,000.
 
     The Board believes that the increase in the number of shares available for
issuance under the Employee Plan will strengthen the Company's ability to
attract, retain and motivate key employees of the Company and motivate such
parties to attain individual performance and overall corporate goals. Currently,
excluding options granted to MICOM employees prior to the spinoff of MICOM and
assuming all of the options granted are ultimately exercised, Black Box
employees would own 10.7% of the outstanding shares. The proposed increase in
the shares available for issuance would increase that percentage to 15% which
based on an independent survey of 85 high technology companies, the similar
percentage was over 20%, therefore, the Board believes this proposed increase is
appropriate. The affirmative vote by the holders of a majority of the shares of
Common Stock entitled to vote and present at the meeting is required to approve
the amendment to the Employee Plan.
 
     Because executive officers (who also may be members of the Board of
Directors) are eligible to receive awards under the Employee Plan, each of them
may be deemed to have a personal interest in the adoption of this proposal.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR APPROVAL OF PROPOSAL 2.
 
                            SUMMARY PLAN DESCRIPTION
 
     The following description is not a complete statement of the Employee Plan
and is qualified in its entirety by reference to the complete text of the
Employee Plan, a copy of which is available from the Company upon request.
 
     ADMINISTRATION. The Employee Plan is administered by a committee consisting
of at least two directors of the Company who are appointed by and serve at the
pleasure of the Board of Directors (the "Option Committee"). The Option
Committee, from time to time at its discretion, makes determinations with
respect to the persons who shall be granted options ("Options") or stock
appreciation rights ("Rights"), the number of shares of the Common Stock that
may be purchased pursuant to such Options or Rights and the designation of
Options as Incentive Stock Options or Non-Qualified Stock Options, as defined
below. The interpretation and construction by the Committee of any provisions of
the Employee Plan or of an Option or
 
                                       13
<PAGE>   16
 
Right granted thereunder is binding and conclusive on all optionees and on their
legal representatives and beneficiaries.
 
     TYPES OF OPTIONS. The Committee, in its discretion, may grant Options to
purchase shares of Common Stock either in the form of incentive stock options
("Incentive Stock Options") qualified as such under the Internal Revenue Code of
1986, as amended (the "Code"), or other options ("Non-Qualified Stock Options"),
as designated in the optionee's stock option agreement. Historically, the
Company has only granted Non-Qualified Stock Options.
 
     RIGHTS. The Committee, in its discretion, may grant Rights either alone,
simultaneously with the grant of an Incentive Stock Option or Non-Qualified
Stock Option and in conjunction therewith, or subsequent to the grant of a
Non-Qualified Stock Option and in conjunction therewith or in the alternative
thereto.
 
     ELIGIBILITY. Any key salaried employee who is not a member of the Option
Committee may be granted Incentive Stock Options, Non-Qualified Stock Options or
Rights under the Employee Plan until November 30, 2002.
 
     EXERCISE PRICE. The Option Committee shall determine the exercise price for
each Option or Right granted under the Employee Plan, provided however, that the
exercise price: (1) in the case of an Incentive Stock Option granted to an
employee, other than an employee who owns more than 10% of the total combined
voting power of all classes of outstanding stock of the Company (a "Ten-Percent
Stockholder"), shall not be less than the fair market value of the shares to
which the Option relates on the date of grant; (2) in the case of an Incentive
Stock Option granted to an employee who is a Ten-Percent Stockholder, shall not
be less than 110% of the fair market value of the shares to which the Option
relates on the date of grant; (3) in the case of a Right granted alone, shall
not be less than 100% of the fair market value of the shares to which the Right
relates.
 
     All Non-Qualified Stock Options granted to date have been at the fair
market value on the date of grant and the Committee anticipates continuing this
practice.
 
     EXERCISE PERIOD AND EXERCISE OF OPTIONS OR RIGHTS. An Option or Right may
be exercised in whole at any time, or in part from time to time, within such
period or periods as may be determined by the Option Committee and set forth in
the grantee's agreement, provided that: (1) no Incentive Stock Option shall be
exercisable after the expiration of ten (10) years from the date of grant; and
(2) no Incentive Stock Option granted to an employee who is a Ten-Percent
Stockholder shall be exercisable after the expiration of five years from its
date of grant. Options granted to date have vested in the grantee after three
years from the date of the grant. Options are not transferable by the optionee
except by will or by the laws of descent and distribution.
 
     TERMINATION OF EMPLOYMENT; DISABILITY; DEATH. Upon termination of
employment, an Option or Right previously granted to an employee, unless
otherwise specified by the Option Committee and to the extent not previously
exercised, shall terminate and become null and void, provided that: (i) if the
employee shall die while in the employ of the Company or within three (3) months
of retirement from such employment or within one (1) year of retirement from
employment by reason of disability, the legal representative or heirs of such
employee shall be entitled to exercise such Option or Right (to the extent
otherwise exercisable) for a one-year period following the date of death; (ii)
if the employment shall have been terminated by reason of retirement, disability
or termination other than for cause (as defined in the Employee Plan), then such
employee shall be entitled to exercise such Option or Right (to the extent
otherwise exercisable) at any time up to (a) three months after termination by
reason of retirement or other than for cause and (b) one (1) year after
termination by reason of disability. If an employee voluntarily terminates his
employment or is terminated for cause, any Option or Right, unless otherwise
specified by the Option Committee, shall immediately terminate.
 
     PAYMENT. The exercise price of shares purchased pursuant to an Option shall
be paid in full at the time of any exercise either in cash or by certified
check; provided, however, to the extent that the terms of such Option provide,
the purchase price may be paid for, in whole or in part, by delivering
previously-owned shares of Common Stock or, in part, by promissory note (for not
more than 80% of such purchase price subject to applicable margin requirements).
 
                                       14
<PAGE>   17
 
     LIMITATION ON ANNUAL AWARDS. The aggregate fair market value of stock for
which Incentive Stock Options are exercisable for the first time by an optionee
during any calendar year under the terms of the Employee Plan shall not exceed
the sum of $100,000.
 
     ADJUSTMENTS, AMENDMENT OR DISCONTINUANCE. In the event of any change in the
outstanding Common Stock through merger, consolidation, reorganization,
recapitalization, stock dividend, stock split, split-up, split-off, spin-off,
combination of shares, exchange of shares, or other like change in capital
structure of the Company, the Option Committee shall make such adjustment to
each outstanding Option and Right that it, in its sole discretion, deems
appropriate. In addition, in the event of any such change, the Option Committee
shall make any further adjustment as may be appropriate to the maximum number of
shares which may be acquired under the Employee Plan pursuant to the exercise of
Options and Rights, the maximum number of shares which may be so acquired by one
employee and the number of shares and prices per share subject to outstanding
Options and Rights as shall be equitable to prevent dilution or enlargement of
rights under such Options or Rights, and the determination of the Option
Committee as to these matters shall be conclusive.
 
     In the event of a "change in control" of the Company, as defined in the
Employee Plan, all then outstanding Options and Rights shall immediately become
exercisable. The Option Committee, in its discretion, may determine that, upon
the occurrence of a change in control transaction, each Option or Right
outstanding under the Employee Plan shall terminate within a specified number of
days after notice to the holder, and such holder shall receive, with respect to
each share subject to such Option or Right, cash in an amount equal to the
excess of the fair market value of such share immediately prior to such
transaction over the exercise price per share of such Option or Right.
 
     The Board of Directors or the Option Committee, as the case may be, may,
from time to time, amend the Employee Plan, provided that no amendment shall be
made, without the approval of the stockholders of the Company, that will (i)
increase the total number of shares reserved for Options under the Employee Plan
(other than an increase resulting from an adjustment of outstanding Common
Stock), (ii) reduce the exercise price of any Incentive Stock Option granted
under the Employee Plan below the price required by the Employee Plan, (iii)
modify the provisions of the Employee Plan relating to eligibility, or (iv)
materially increase the benefits accruing to participants under the Employee
Plan. The rights and obligations under any Option or Right granted before
amendment of the Employee Plan or any unexercised portion of such Option or
Right shall not be adversely affected by amendment of the Employee Plan, Option
or Right without the consent of the holder of such Option or Right. The Board of
Directors may at any time suspend or terminate the Employee Plan.
 
     TERM OF PLAN. Options and Rights may be granted under the Employee Plan
until November 30, 2002.
 
                        FEDERAL INCOME TAX CONSEQUENCES
 
     The following summary is based upon an interpretation of present federal
tax laws and regulations and may be inapplicable if such laws and regulations
are changed. The Employee Plan is not subject to the protective provisions of
the Employee Retirement Income Security Act of 1974 and is not qualified under
Section 401(a) of the Code.
 
     An optionee will not be required to recognize any income for federal income
tax purposes at the time of grant of an Incentive Stock Option, nor is the
Company entitled to any deduction. The exercise of an Incentive Stock Option is
also not a taxable event, although the difference between the option price and
the fair market value on the date of exercise is an item of tax preference for
purposes of the alternative minimum tax. If stock acquired upon exercise of an
Incentive Stock Option is held for two years from the date the Option was
granted and one year from the date the stock was transferred to the optionee
(the "ISO Holding Period"), then the optionee will have a long-term capital gain
or loss on the sale of such stock measured by the difference between the amount
realized and the option price. If the ISO Holding Period is not met, then, upon
disposition of such shares (a "disqualifying disposition"), the optionee will
realize compensation taxable as ordinary income in an amount equal to the excess
of the fair market value of the shares at the time of exercise over the option
price, limited, however, to the gain on sale. Any additional gain would be
taxable as long-term
 
                                       15
<PAGE>   18
 
or short-term capital gain. If the Incentive Stock Option is exercised by
delivery of previously-owned shares of common stock in partial or full payment
of the option price, no gain or loss will ordinarily be recognized by the
optionee on the transfer of such previously-owned shares. However, if the
previously-owned shares transferred were acquired through the exercise of an
Incentive Stock Option, the optionee may realize ordinary income with respect to
the shares used to exercise an Incentive Stock Option if such transferred shares
have not been held for the ISO Holding Period. If the optionee recognizes
ordinary income upon a disqualifying disposition, the Company generally will be
entitled to a tax deduction in the same amount.
 
     An optionee will not be required to recognize any income for federal income
tax purposes at the time of grant of a Non-Qualified Stock Option, nor is the
Company then entitled to any deduction. Upon exercise of a Non-Qualified Stock
Option, the optionee will realize compensation taxable as ordinary income in an
amount measured by the excess, if any, of the fair market value of the shares on
the date of exercise over the option price. The Company will be entitled to a
deduction in the same amount and at the same time. Upon the sale of shares
acquired on exercise of a Non-Qualified Stock Option, the optionee will realize
capital gain (or loss) measured by the difference between the amount realized
and the fair market value of the shares on the date of exercise. If the exercise
price of a Non-Qualified Stock Option is paid in whole or in part in shares of
common stock, the tax results to the optionee are (i) a tax-free exchange of
previously owned shares for an equivalent number of new shares and (ii) the
realization of ordinary income in an amount equal to the fair market value on
the date of exercise of any additional shares received in excess of the number
exchanged.
 
     The foregoing rules regarding time of taxation of optionees upon the
disposition of stock acquired upon the exercise of an Incentive Stock Option and
upon the exercise of a Non-Qualified Stock Option may differ somewhat with
respect to Options that are exercised within six months of the date of grant by
optionees who are subject to the short-swing profit restrictions of Section
16(b) of the Exchange Act.
 
     If the option price is paid by an optionee in part by promissory note, the
interest paid by the optionee under the promissory note is investment
indebtedness which is deductible by the optionee as an itemized deduction from
gross income to the extent the optionee has net investment income; interest that
is disallowed because of this limitation may be carried over to succeeding tax
years and is deductible in the carryover year, subject to the net investment
income limitation.
 
     Rights are treated very similarly to Options for tax purposes. The holder
of a Right will not normally realize any taxable income upon the grant of a
Right. Upon the exercise of a Right, the person exercising the Right will
realize compensation taxable as ordinary income equal to either (i) the cash
received upon the exercise of the Right or (ii) if shares are received upon the
exercise of the Right, the fair market value of such shares as of the exercise
date. The basis of any shares acquired upon exercise of a Right will be their
fair market value on the date of exercise, and the holding period will commence
at that time. The Company will be entitled to a deduction for compensation paid
in the same amount which the holder of the Right realizes as ordinary income.
 
PROPOSAL 3
 
                    APPROVAL OF AN INCREASE IN THE NUMBER OF
                       AUTHORIZED SHARES OF COMMON STOCK
 
     On May 6, 1997, the Board of Directors adopted a resolution proposing that
Article Fourth of the Certificate of Incorporation of the Company be amended to
increase the authorized number of shares of the stock of the Company from
25,000,000 shares to 45,000,000 shares consisting of 40,000,000 shares of Common
Stock and 5,000,000 shares of Preferred Stock. The Board directed that the
proposed amendment be submitted to a vote of the stockholders at the Annual
Meeting.
 
     Proposed Article Fourth would increase the total number of authorized
shares of Common Stock of the Company from 20,000,000 to 40,000,000. The
amendment will not change the 5,000,000 authorized shares of Preferred Stock. On
May 20, 1997, 16,561,345 shares of Common Stock were issued and outstanding.
 
                                       16
<PAGE>   19
 
     The Board of Directors is not negotiating nor does it have any present
plans for the issuance of additional shares, other than pursuant to existing
stock option plans, but in the judgment of the Board the additional shares
should be authorized so that they will be available for issuance from time to
time by action of the Board if the need should arise. For example, if it should
become desirable to implement financing through the sale of additional shares of
stock, make an acquisition by the issuance of stock, or effect a stock split by
way of a stock dividend or distribution, such additional shares may be used for
such purposes. The Board believes that increasing the authorized shares of
Common Stock would enable it, if it so chooses, to take actions promptly on
behalf of the Company that may involve the issuance of additional shares of
Common Stock without the delay necessarily incident to the convening of a
stockholders' meeting. After adoption of the proposed amendment, the Board of
Directors, without further action by the stockholders, would have authority to
issue additional authorized and unissued shares of Common Stock at such times,
for a consideration of such character and value (not less than par), and upon
such terms, as it may deem advisable and in accordance with the Delaware General
Corporation Law. In certain circumstances, a vote of the stockholders on the
issuance of additional shares will be required under the rules of the Nasdaq
National Market.
 
     The authorization of these additional shares of Common Stock will not
materially affect any substantive rights, powers or privileges of the current
holders of shares of the Common Stock. The current holders of Common Stock have
no preemptive rights to subscribe to the issuance of any additional shares, and
this proposal could have the effect of diluting the holdings of all current
stockholders, if, in fact, additional shares were to be issued to new holders.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR APPROVAL OF PROPOSAL 3.
 
PROPOSAL 4
 
         RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
     Subject to stockholder ratification, the Board of Directors, upon
recommendation of the Audit Committee, has appointed Arthur Andersen LLP as the
independent public accountants of the Company for the fiscal year ending March
31, 1998. The affirmative vote of a majority of the shares of Common Stock
present and entitled to vote on this matter at the meeting is required for the
ratification of such appointment.
 
     Unless otherwise directed by the stockholders, proxies will be voted for
the ratification of the appointment of Arthur Andersen LLP as independent
accountants of the Company for the fiscal year ending March 31, 1998. A
representative of Arthur Andersen LLP is expected to be present at the Annual
Meeting, will not be making a statement and will be available to respond to
appropriate questions.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR APPROVAL OF PROPOSAL 4.
 
                   FORM 10-K ANNUAL REPORT TO THE SECURITIES
                            AND EXCHANGE COMMISSION
 
     A copy of the Annual Report on Form 10-K of the Company for the fiscal year
ended March 31, 1997, as filed with the Securities and Exchange Commission, is
available to stockholders. A stockholder may obtain a copy of the Form 10-K
without charge and a copy of any exhibits thereto upon payment of a reasonable
charge limited to the Company's costs of providing such exhibits by writing to
Investor Relations Department, Anna M. Baird, Chief Financial Officer, Black Box
Corporation, 1000 Park Drive, Lawrence, Pennsylvania 15055.
 
                                 OTHER MATTERS
 
     The Company knows of no other matters to be presented for action at the
meeting. However, if any other matters should properly come before the meeting,
it is intended that votes will be cast pursuant to the proxy in respect thereto
in accordance with the best judgment of the persons acting as proxies.

assembling and mailing to the holders of Common Stock of the Company the notice
of meeting, this proxy statement and the accompanying form of proxy. In addition
to the use of the mails, proxies may be solicited by directors, officers or
regular employees of the Company personally or by telephone or telegraph. The
Company may request the persons holding stock in their names, or in the names of
their nominees, to send proxy material to, and obtain proxies from, their
principals, and will reimburse such persons for their expense in so doing.

                                                                    Appendix

                             BLACK BOX CORPORATION
                             1992 STOCK OPTION PLAN
                      (AS AMENDED THROUGH AUGUST 12, 1996)

         I.  PURPOSES

         BLACK BOX CORPORATION (the "Company") desires to afford certain of its
key employees and the key employees of any subsidiary corporation or parent
corporation of the Company now existing or hereafter formed or acquired who are
responsible for the continued growth of the Company an opportunity to acquire a
proprietary interest in the Company, and thus to create in such key employees
an increased interest in and a greater concern for the welfare of the Company
and its subsidiaries.

         The Company, by means of this 1992 Stock Option Plan as originally
approved on November 11, 1992, and as further amended on May 10,1994, August 9,
1994, August 7, 1995 and August 12, 1996 (the "Plan"), seeks to retain the
services of persons now holding key positions and to secure the services of
persons capable of filling such positions.

         The stock options ("Options") and stock appreciation rights ("Rights")
offered pursuant to the Plan are a matter of separate inducement and are not in
lieu of any salary or other compensation for the services of any key employee.

         The Options granted under the Plan are intended to be either incentive
stock options ("Incentive Options") within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), or options that do not
meet the requirements for Incentive Options ("Non-Qualified Options"), but the
Company makes no warranty as to the qualification of any Option as an Incentive
Option.

         II.  AMOUNT OF STOCK SUBJECT TO THE PLAN

         The total number of shares of common stock of the Company which may be
purchased or acquired pursuant to the exercise of Options or Rights granted
under the Plan shall not exceed, in the aggregate, 2,450,000 shares of the
authorized common stock, $.001 par value per share, of the Company (the
"Shares"), such number subject to adjustment as provided in Article XII hereof.
Shares that are the subject of Rights and related Options shall be counted only
once in determining whether the maximum number of Shares that may be purchased
or awarded under the Plan has been exceeded.

         Shares acquired under the Plan may be either authorized but unissued
Shares or Shares of issued stock held in the Company's treasury, or both, at
the discretion of the Company. If and to the extent that Options or Rights
granted under the Plan expire or terminate without having been exercised, the
Shares covered by such expired or terminated Options or Rights shall again
become available for award under the Plan.

         Except as provided in Articles XIX and XXII and subject to Article II,
the Company may, from time to time during the period beginning on the date on
which the Company consummates an underwritten initial public offering of Shares
(the "Effective Date") and ending on November 30, 2002 (the "Termination
Date"), grant to certain key employees of the Company, or of any subsidiary
corporation or parent corporation of the Company now existing or hereafter
formed or acquired, Incentive Options and/or Non-Qualified Options and/or
Rights under the terms hereinafter set forth.

         Provisions of the Plan that pertain to Options or Rights granted to an
employee shall apply to Options, Rights or a combination thereof.

         As used in the Plan, the term "subsidiary corporation" and "parent
corporation" shall mean, respectively, a corporation coming within the
definition of such terms contained in Sections 424(f) and 424(e) of the Code.


<PAGE>   22

         III.  ADMINISTRATION

         The board of directors of the Company (the "Board of Directors") shall
designate from among its members an option committee, which may be the
Compensation Committee of the Board of Directors (the "Committee"), to
administer the Plan. The Committee shall consist of no fewer than two members
of the Board of Directors, each of whom shall be a "disinterested person"
within the meaning of Rule 16b-3 (or any successor rule or regulation)
promulgated under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). A majority of the members of the Committee shall constitute a
quorum, and the act of a majority of the members of the Committee shall be the
act of the Committee.  Any member of the Committee may be removed at any time
either with or without cause by resolution adopted by the Board of Directors,
and any vacancy on the Committee at any time may be filled by resolution
adopted by the Board of Directors.

         Subject to the express provisions of the Plan the Committee shall have
authority, in its discretion, to determine the employees to whom Options or
Rights shall be granted, the time when such Options or Rights shall be granted,
the number of Shares which shall be subject to each Option or Right, the
purchase price or exercise price of each Option or Right, the period(s) during
which such Options or Rights shall become exercisable (whether in whole or in
part) and the other terms and provisions thereof (which need not be identical).

         Subject to the express provisions of the Plan, the Committee also
shall have authority to construe the Plan and the Options and Rights granted
thereunder, to amend the Plan and the Options and Rights granted thereunder, to
prescribe, amend and rescind rules and regulations relating to the Plan, to
determine the terms and provisions of the Options (which need not be identical)
and Rights (which need not be identical) granted thereunder and to make all
other determinations necessary or advisable for administering the Plan. The
Committee also shall have the authority to require, in its discretion, as a
condition of the granting of any such Option or Right, that the employee agree
(i) not to sell or otherwise dispose of Shares acquired pursuant to the
exercise of such Option or Right for a period of six (6) months following the
date of the acquisition of such Option or Right and (ii) that in the event of
termination of employment of such employee, other than as a result of dismissal
without cause, such employee will not, for a period to be fixed at the time of
the grant of the Option or Right, enter into any other employment or
participate directly or indirectly in any other business or enterprise which is
competitive with the business of the Company or any subsidiary corporation or
parent corporation of the Company, or enter into any employment in which such
employee will be called upon to utilize special knowledge obtained through
employment with the Company or any subsidiary corporation or parent corporation
thereof. In no event will an employee who is subject to the reporting
requirements of Section 16(a) of the Exchange Act be entitled to sell or
otherwise dispose of any Shares acquired pursuant to exercise of any such
Options or Rights for a period of six (6) months from the date of the
acquisition of such Options or Rights.

         The determination of the Committee on matters referred to in this
Article III shall be conclusive.

         The Committee may employ such legal counsel, consultants and agents as
it may deem desirable for the administration of the Plan and may rely upon any
opinion or computation received from any such legal counsel, consultant or
agent. Expenses incurred by the Committee in the engagement of such counsel,
consultant or agent shall be paid by the Company. No member or former member of
the Committee shall be liable for any action or determination made in good
faith with respect to the Plan or any award of Options or Rights granted
hereunder.

         IV.  ELIGIBILITY

         Options and Rights may be granted only to salaried key employees of
the Company or of any subsidiary corporation or parent corporation of the
Company, except as hereinafter provided, and shall not be granted to any
officer or director who is not also a salaried key employee or to any member of
the Committee. Any person who shall have retired from active employment by the
Company or a subsidiary corporation or parent corporation thereof, although
such person shall have entered into a consulting contract with the Company or a
subsidiary corporation or parent corporation thereof, shall not be eligible to
receive an Option or a Right.

                                      -2-

<PAGE>   23

         The Plan does not create a right in any employee to participate in the
Plan, nor does it create a right in any employee to have any Options or Rights
granted to him or her.

         V.  OPTION PRICE AND PAYMENT

         The price for each Share purchasable under any Non-Qualified Option
granted hereunder shall be such amount as the Committee shall deem appropriate.

         The price for each Share purchasable under any Incentive Option
granted hereunder shall be such amount as the Committee shall, in its best
judgment, determine to be not less than one hundred percent (100%) of the fair
market value per Share at the date the Option is granted; provided, however,
that in the case of an Incentive Option granted to a person who, at the time
such Option is granted, owns shares of the Company or any subsidiary
corporation or parent corporation of the Company which possesses more than ten
percent (10%) of the total combined voting power of all classes of shares of
the Company or of any subsidiary corporation or parent corporation of the
Company, the purchase price for each Share shall be such amount as the
Committee in its best judgment shall determine to be not less than one hundred
ten percent (110%) of the fair market value per Share at the date the Option is
granted. In determining stock ownership of an employee for any purposes under
the Plan, the rules of Section 424(d) of the Code shall be applied, and the
Committee may rely on representations of fact made to it by the employee and
believed by it to be true.

         If the Shares are listed on a national securities exchange in the
United States (which, for purposes of this Article V, shall be deemed to
include any last sale reported over-the-counter market), on any date on which
the fair market value per Share is to be determined, the fair market value per
Share shall be deemed to be the average of the high and low quotations at which
such Shares are sold on such national securities exchange on the date such
Option is granted. If the Shares are listed on a national securities exchange
in the United States on such date, but the Shares are not traded on such date,
or such national securities exchange is not open for business on such date, the
fair market value per Share shall be determined as of the closest preceding
date on which such exchange shall have been open for business and the Shares
shall have been traded. If the Shares are listed on more than one national
securities exchange in the United States on the date on which the fair market
value per Share is to be determined, the Committee shall determine which
national securities exchange shall be used for the purpose of determining the
fair market value per Share.

         If a public market exists for the Shares on any date on which the fair
market value per Share is to be determined but the Shares are not listed on a
national securities exchange in the United States, the fair market value per
Share shall be deemed to be the mean between the closing bid and asked
quotations in the over-the-counter market for the Shares on such date. If there
are no bid and asked quotations for the Shares on such date, the fair market
value per Share shall be deemed to be the mean between the closing bid and
asked quotations in the over-the-counter market for the Shares on the closest
date preceding such date for which such quotations are available.

         If no public market exists for the Shares on any date on which the
fair market value per Share is to be determined, the Committee shall, in its
sole discretion and best judgment, determine the fair market value of a Share.

         For purposes of this Plan, the determination by the Committee of the
fair market value of a Share shall be conclusive.

         Upon the exercise of an Option granted hereunder, the Company shall
cause the purchased Shares to be issued only when it shall have received the
full purchase price for the Shares in cash or by certified check; provided,
however, that in lieu of cash, the holder of an Option may, if and to the
extent the terms of such Option so provide and to the extent permitted by
applicable law, exercise an Option (i) in whole or in part, by delivering to
the Company shares of common stock of the Company (in proper form for transfer
and accompanied by all

                                      -3-

<PAGE>   24

requisite stock transfer tax stamps or cash in lieu thereof) owned by such
holder having a fair market value equal to the exercise price applicable to
that portion of the Option being exercised by the delivery of such Shares or
(ii) in part, by delivering to the Company an executed promissory note on such
terms and conditions as the Committee shall determine, at the time of grant, in
its sole discretion; provided, however, that the principal amount of such note
shall not exceed eighty percent (80%) (or such lesser percentage as would be
permitted by applicable margin regulations) of the aggregate purchase price of
the Shares then being purchased pursuant to the exercise of such Option. The
fair market value of the stock so delivered shall be determined as of the date
immediately preceding the date on which the Option is exercised, or as may be
required in order to comply with or to conform to the requirements of any
applicable laws or regulations.

         VI.  USE OF PROCEEDS

         The cash proceeds of the sale of Shares pursuant to the Plan are to be
added to the general funds of the Company and used for its general corporate
purposes as the Board of Directors shall determine.

         VII.  TERM OF OPTIONS AND LIMITATIONS ON THE RIGHT OF EXERCISE

         Any Option shall be exercisable at such times, in such amounts and
during such period or periods as the Committee shall determine at the date of
the grant of such Option; provided, however, that an Incentive Option shall not
be exercisable after the expiration of ten (10) years from the date such Option
is granted; and provided further that, in the case of an Incentive Option
granted to a person who, at the time such Option is granted, owns stock of the
Company or any subsidiary corporation or parent corporation of the Company
possessing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or of any subsidiary corporation or parent
corporation of the Company, such Option shall not be exercisable after the
expiration of five (5) years from the date such Option is granted.

         Except to the extent otherwise provided under the Code, to the extent
that the aggregate fair market value of stock for which Incentive Options are
exercisable for the first time by an employee during any calendar year (under
all stock option plans of the Company and of any parent corporation or
subsidiary corporation of the Company) exceeds one hundred thousand dollars
($100,000), such Options shall be treated as Non-Qualified Options. For
purposes of this limitation, (i) the fair market value of stock is determined
as of the time the Option is granted, and (ii) the limitation will be applied
by taking into account Options in the order in which they were granted.

         Subject to the provisions of Article XVIII, the Committee shall have
the right to accelerate, in whole or in part, from time to time, conditionally
or unconditionally, rights to exercise any Option granted hereunder.

         To the extent that an Option is not exercised within the period of
exercisability specified therein, it shall expire as to the then unexercised
part.

         In no event shall an Option granted hereunder be exercised for a
fraction of a Share.

         VIII.  EXERCISE OF OPTIONS

         Options granted under the Plan shall be exercised by the optionee as
to all or part of the Shares covered thereby by the giving of written notice of
the exercise thereof to the Corporate Secretary of the Company at the principal
business office of the Company, specifying the number of Shares to be purchased
and specifying a business day not more than fifteen (15) days from the date
such notice is given for the payment of the purchase price against delivery of
the Shares being purchased. Subject to the terms of Articles XIV, XVI, and
XVII, the Company shall cause certificates for the Shares so purchased to be
delivered to the optionee at the principal business office of the Company,
against payment of the full purchase price, on the date specified in the notice
of exercise.

                                      -4-

<PAGE>   25

         IX.  STOCK APPRECIATION RIGHTS

         In the discretion of the Committee, a Right may be granted (i) alone,
(ii) simultaneously with the grant of an Option (either Incentive or
Non-Qualified) and in conjunction therewith or in the alternative thereto or
(iii) subsequent to the grant of a Non-Qualified Option and in conjunction
therewith or in the alternative thereto.

         The exercise price of a Right granted alone shall be determined by the
Committee but shall not be less than one hundred percent (100%) of the fair
market value of one Share on the date of grant of such Right. A Right granted
simultaneously with or subsequent to the grant of an Option and in conjunction
therewith or in the alternative thereto shall have the same exercise price as
the related Option, shall be transferable only upon the same terms and
conditions as the related Option, and shall be exercisable only to the same
extent as the related Option; provided, however, that a Right, by its terms,
shall be exercisable only when the fair market value of the Shares subject to
the Right and related Option exceeds the exercise price thereof.

         Upon exercise of a Right granted simultaneously with or subsequent to
an Option and in the alternative thereto, the number of Shares for which the
related Option shall be exercisable shall be reduced by the number of Shares
for which the Right shall have been exercised. The number of Shares for which a
Right shall be exercisable shall be reduced upon any exercise of a related
Option by the number of Shares for which such Option shall have been exercised.

         Any Right shall be exercisable upon such additional terms and
conditions as may from time to time be prescribed by the Committee.

         A Right shall entitle the holder upon exercise thereof to receive from
the Company, upon a written request filed with the Secretary of the Company at
its principal offices (the "Request"), a number of Shares (with or without
restrictions as to substantial risk of forfeiture and transferability, as
determined by the Committee in its sole discretion), an amount of cash, or any
combination of Shares and cash, as specified in the Request (but subject to the
approval of the Committee in its sole discretion, at any time up to and
including the time of payment, as to the making of any cash payment), having an
aggregate fair market value equal to the product of (i) the excess of the fair
market value, on the day of such Request, of one Share over the exercise price
per share specified in such Right or its related Option, multiplied by (ii) the
number of Shares for which such Right shall be exercised.

         Any election by a holder of a Right to receive cash in full or partial
settlement of such Right, and any exercise of such Right for cash, may be made
only by a Request filed with the Corporate Secretary of the Company during the
period beginning on the third business day following the date of release for
publication by the Company of quarterly or annual summary statements of sales
and earnings and ending on the twelfth business day following such date. Within
thirty (30) days of the receipt by the Company of a Request to receive cash in
full or partial settlement of a Right or to exercise such Right for cash, the
Committee shall, in its sole discretion, either consent to or disapprove, in
whole or in part, such Request. A Request to receive cash in full or partial
settlement of a Right or to exercise a Right for cash may provide that, in the
event the Committee shall disapprove such Request, such Request shall be deemed
to be an exercise of such Right for Shares.

         If the Committee disapproves in whole or in part any election by a
holder to receive cash in full or partial settlement of a Right or to exercise
such Right for cash, such disapproval shall not affect such holder's right to
exercise such Right at a later date, to the extent that such Right shall be
otherwise exercisable, or to elect the form of payment at a later date,
provided that an election to receive cash upon such later exercise shall be
subject to the approval of the Committee. Additionally, such disapproval shall
not affect such holder's right to exercise any related Option or Options
granted to such holder under the Plan.

                                      -5-

<PAGE>   26

         A holder of a Right shall not be entitled to request or receive cash
in full or partial payment of such Right unless such Right shall have been held
for six (6) months from the date of acquisition to the date of cash settlement
thereof; provided, however, that such prohibition shall not apply if the holder
of such Right is not subject to the reporting requirements of Section 16(a) of
the Exchange Act. In no event will a holder of a Right who is subject to the
reporting requirements of Section 16(a) of the Exchange Act be entitled to make
such a request or receive cash in full or partial payment of such Right until
the Company shall have satisfied the informational requirements of Rule
16b-3(e)(1) promulgated under the Exchange Act for the specified one year
period.

         A Right shall be deemed exercised on the last day of its term, if not
otherwise exercised by the holder thereof, provided that the fair market value
of the Shares subject to the Right exceeds the exercise price thereof on such
date.

         For all purposes of this Article IX, the fair market value of Shares
shall be determined in accordance with the principles set forth in the Article
V.

         X.  NON-TRANSFERABILITY OF OPTIONS AND STOCK APPRECIATION RIGHTS

         Neither an Option nor a Right granted hereunder shall be transferable,
whether by operation of law or otherwise, other than by will or the laws of
descent and distribution, and any Option or Right granted hereunder shall be
exercisable during the lifetime of the holder only by such holder. Except to
the extent provided above, Options and Rights may not be assigned, transferred,
pledged, hypothecated or disposed of in any way (whether by operation of law or
otherwise) and shall not be subject to execution, attachment or similar
process.

         XI.  TERMINATION OF EMPLOYMENT

         Upon termination of employment of any employee with the Company and
all subsidiary corporations and parent corporations of the Company, an Option
or Right previously granted to the employee, unless otherwise specified by the
Committee in the Option or Right, shall, to the extent not theretofore
exercised, terminate and become null and void, provided that:

                  (a) if the employee shall die while in the employ of such
         corporation or during either the three (3) month or one (1) year
         period, whichever is applicable, specified in clause (b) below and at
         a time when such employee was entitled to exercise an Option or Right
         as herein provided, the legal representative of such employee, or such
         person who acquired such Option or Right by bequest or inheritance or
         by reason of the death of the employee, may, not later than one (1)
         year from the date of death, exercise such Option or Right, to the
         extent not theretofore exercised, in respect of any or all of such
         number of Shares as specified by the Committee in such Option or
         Right; and

                  (b) if the employment of an employee to whom such Option or
         Right shall have been granted shall terminate by reason of the
         employee's retirement (at such age or upon such conditions as shall be
         specified by the Board of Directors), disability (as described in
         Section 22(e)(3) of the Code) or dismissal by the employer other than
         for cause (as defined below), and while such employee is entitled to
         exercise such Option or Right as herein provided, such employee shall
         have the right to exercise such Option or Right so granted, to the
         extent not theretofore exercised, in respect of any or all of such
         number of Shares as specified by the Committee in such Option or
         Right, at any time up to and including (i) three (3) months after the
         date of such termination of employment in the case of termination by
         reason of retirement or dismissal other than for cause and (ii) one
         (1) year after the date of termination of employment in the case of
         termination by reason of disability.

                                      -6-

<PAGE>   27

         If an employee voluntarily terminates his or her employment, or is
discharged for cause, any Option or Right granted hereunder shall, unless
otherwise specified by the Committee in the Option or Right, forthwith
terminate with respect to any unexercised portion thereof.

         If an Option or Right granted hereunder shall be exercised by the
legal representative of a deceased or disabled employee or former employee, or
by a person who acquired an Option or Right granted hereunder by bequest or
inheritance or by reason of death of any employee or former employee, written
notice of such exercise shall be accompanied by a certified copy of letters
testamentary or equivalent proof of the right of such legal representative or
other person to exercise such Option or Right.

         For the purposes of the Plan, the term "for cause" shall mean (i) with
respect to an employee who is party to a written agreement with, or,
alternatively, participates in a compensation or benefit plan of the Company or
a subsidiary corporation or parent corporation of the Company, which agreement
or plan contains a definition of "for cause" or "cause" (or words of like
import) for purposes of termination of employment thereunder by the Company or
such subsidiary corporation or parent corporation of the Company, "for cause"
or "cause" as defined in the most recent of such agreements or plans, or (ii)
in all other cases, (a) the willful commission by an employee of a criminal or
other act that causes substantial economic damage to the Company or a
subsidiary corporation or parent corporation of the Company or substantial
injury to the business reputation of the Company or a subsidiary corporation or
parent corporation of the Company; (b) the commission by an employee of an act
of fraud in the performance of such employee's duties on behalf of the Company
or a subsidiary corporation or parent corporation of the Company; or (c) the
continuing willful failure of an employee to perform the duties of such
employee to the Company or a subsidiary corporation or parent corporation of
the Company (other than such failure resulting from the employee's incapacity
due to physical or mental illness) after written notice thereof (specifying the
particulars thereof in reasonable detail) and a reasonable opportunity to be
heard and cure such failure are given to the employee by the Board of Directors
or the Committee. For purposes of the Plan, no act, or failure to act, on the
employee's part shall be considered "willful" unless done or omitted to be done
by the employee not in good faith and without reasonable belief that the
employee's action or omission was in the best interest of the Company or a
subsidiary corporation or parent corporation of the Company.

         For the purposes of the Plan, an employment relationship shall be
deemed to exist between an individual and a corporation if, at the time of the
determination, the individual was an "employee" of such corporation for
purposes of Section 422(a) of the Code. If an individual is on military, sick
leave or other bona fide leave of absence, such individual shall be considered
an "employee" for purposes of the exercise of an Option or Right and shall be
entitled to exercise such Option or Right during such leave if the period of
such leave does not exceed 90 days, or, if longer, so long as the individual's
right to reemployment with the corporation granting the option (or a related
corporation) is guaranteed either by statute or by contract. If the period of
leave exceeds ninety (90) days, the employment relationship shall be deemed to
have terminated on the ninety-first (91st) day of such leave, unless the
individual's right to reemployment is guaranteed by statute or contract.

         A termination of employment shall not be deemed to occur by reason of
(i) the transfer of an employee from employment by the Company to employment by
a subsidiary corporation or a parent corporation of the Company or (ii) the
transfer of an employee from employment by a subsidiary corporation or a parent
corporation of the Company to employment by the Company or by another
subsidiary corporation or parent corporation of the Company. Furthermore,
solely for purposes of determining the rights and obligations under any
outstanding Options or Rights theretofore granted, in the event that the
Company ceases to own, directly or indirectly, stock possessing 50% or more of
the total combined voting power of all classes of stock of a subsidiary company
by virtue of a recapitalization, stock dividend, stock split, split-up,
spin-off, combination of shares or other like change in capital structure of
the Company, the Committee may determine that employment by such former
subsidiary (or any parent or subsidiary company of such subsidiary) shall
continue to be deemed to be employment by the Company for purposes of the Plan.

                                      -7-

<PAGE>   28

         In the event of the complete liquidation or dissolution of a
subsidiary corporation, or in the event that the Company ceases to own,
directly or indirectly, stock possessing 50% or more of the total combined
voting power of all classes of stock of such corporation, any unexercised
Options or Rights theretofore granted to any person employed by such subsidiary
corporation will be deemed canceled unless such person is employed by the
Company or by any parent corporation or another subsidiary corporation after
the occurrence of such event. In the event an Option or Right is to be canceled
pursuant to the provisions of the previous sentence, notice of such
cancellation will be given to each employee holding unexercised Options or
Rights and such holder will have the right to exercise such Options or Rights
in full (without regard to any limitation set forth or imposed pursuant to
Article VII) during the 30 day period following notice of such cancellation.

         Notwithstanding anything to the contrary contained in this Article XI,
in no event, however, shall any person be entitled to exercise any Option or
Right after the expiration of the period of exercisability of such Option or
Right as specified therein.

           XII.  ADJUSTMENT OF SHARES; EFFECT OF CERTAIN TRANSACTIONS

         In the event of any change in the outstanding Shares through merger,
consolidation, reorganization, recapitalization, stock dividend, stock split,
split-up, split-off, spin-off, combination of shares, exchange of shares,
issuance of rights to subscribe for Shares, or other like change in capital
structure of the Company, the Committee shall make such adjustment to each
outstanding Option and Right that it, in its sole discretion, deems
appropriate.  The term "Shares" after any such change shall refer to the
securities, cash and/or property then receivable upon exercise of an Option or
Right. In addition, in the event of any such change, the Committee shall make
any further adjustments as may be appropriate to the maximum number of Shares
which may be acquired under the Plan pursuant to the exercise of Options and
Rights, the maximum number of Shares which may be so acquired by one employee
and the number of Shares and prices per Share subject to outstanding Options
and Rights as shall be equitable to prevent dilution or enlargement of rights
under such Options or Rights, and the determination of the Committee as to
these matters shall be conclusive. Notwithstanding the foregoing, (i) each such
adjustment with respect to an Incentive Option and any related Right shall
comply with the rules of Section 424(a) of the Code and (ii) in no event shall
any adjustment be made which would render any Incentive Option granted
hereunder to be other than an "incentive stock option" for purposes of Section
422 of the Code.

         In the event of a "change in control" of the Company, all then
outstanding Options and Rights shall immediately become exercisable. For
purposes of the Plan, a "change in control" of the Company occurs if: (a) any
"Person" (as such term is used in Sections 13(d) and 14(d)(2) of the Exchange
Act), other than Odyssey Partners, L.P. and its affiliates (which, for purposes
of this Article XII only, is deemed to include E.R. Yost) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly of securities of the Company representing (i) 50% or more of the
combined voting power of the Company's then-outstanding securities; or (ii) 25%
or more but less than 50% of the combined voting power of the Company's
then-outstanding securities if such transaction(s) giving rise to such
beneficial ownership are not approved by the Company's Board of Directors; or
(b) at any time a majority of the members of the Board of Directors has been
elected or designated by any Person, other than Odyssey Partners, L.P. and its
affiliates (which, for purposes of this Article XII only, is deemed to include
E.R. Yost); or (c) the Board of Directors shall approve a sale of all or
substantially all of the assets of the Company or any merger, consolidation,
issuance of securities or purchase of assets, in all cases other than to or
with Odyssey Partners, L.P. or its affiliates (which, for purposes of this
Article XII only, is deemed to include E.R. Yost), the result of which would be
the occurrence of any event described in clause (a) or (b) above.

         The Committee, in its discretion, may determine that, upon the
occurrence of a transaction described in the preceding paragraph, each Option
or Right outstanding hereunder shall terminate within a specified number of
days after notice to the holder, and such holder shall receive, with respect to
each Share subject to such Option or Right, cash in an amount equal to the
excess of the fair market value of such Shares immediately prior to the
occurrence of such transaction over the exercise price per share of such Option
or Right. The provisions contained in the preceding sentence shall be
inapplicable to an Option or Right granted within six (6) months before the
occurrence of a transaction described above if the holder of such Option or
Right is subject to the reporting requirements of Section 16(a) of the Exchange
Act.

                                      -8-

<PAGE>   29

         XIII.  RIGHT TO TERMINATE EMPLOYMENT

         The Plan shall not impose any obligation on the Company or on any
subsidiary corporation or parent corporation thereof to continue the employment
of any holder of Options or Rights and it shall not impose any obligation on
the part of any holder of Options or Rights to remain in the employ of the
Company or of any subsidiary corporation or parent corporation thereof.

         XIV.  PURCHASE FOR INVESTMENT

         Except for hereinafter provided, the Committee may require an
employee, as a condition upon exercise of any Option or Right granted
hereunder, to execute and deliver to the Company (a) stock powers with respect
to Shares underlying a particular Option or Right and required to be held by a
custodian, and (b) a written statement, in form satisfactory to the Committee
in which the employee represents and warrants that Shares are being acquired
for such person's own account for investment only and not with a view to the
resale or distribution thereof. The employee shall, at the request of the
Committee, be required to represent and warrant in writing that any subsequent
resale or distribution of Shares by the Employee shall be made only pursuant to
either (i) a Registration Statement on an appropriate form under the Securities
Act of 1933, as amended (the "Securities Act"), which Registration Statement
has become effective and is current with regard to the Shares being sold, or
(ii) a specific exemption from the registration requirements of the Securities
Act, but in claiming such exemption the employee shall, prior to any offer of
sale or sale of such Shares, obtain a prior favorable written opinion of
counsel, in form and substance satisfactory to counsel for the Company, as to
the application of such exemption thereto. The foregoing restriction shall not
apply to (i) issuances by the Company so long as the Shares being issued are
registered under the Securities Act and a prospectus in respect thereof is
current or (ii) re-offerings of Shares by affiliates of the Company (as defined
in Rule 405 or any successor rule or regulation promulgated under the
Securities Act) if the Shares being re-offered are registered under the
Securities Act and a prospectus in respect thereof is current.

            XV.  ISSUE OF CERTIFICATES, LEGENDS, PAYMENT OF EXPENSES

         Upon any exercise of an Option or Right which may be granted hereunder
and, in the case of an Option, payment of the purchase price, a certificate or
certificates for the Shares shall be issued by the Company in the name of the
person exercising the Option or Right and shall be delivered to or upon the
order of such person.

         The Company may endorse such legend or legends upon the certificates
for Shares issued pursuant to the Plan and may issue such "stop transfer"
instructions to its transfer agent in respect of such Shares as, in its
discretion, it determines to be necessary or appropriate to (i) prevent a
violation of, or to perfect an exemption from, the registration requirements of
the Securities Act, (ii) implement the provisions of the Plan and any agreement
between the Company and the optionee or grantee with respect to such Shares, or
(iii) permit the Company to determine the occurrence of a disqualifying
disposition, as described in Section 421(b) of the Code, of Shares transferred
upon exercise of an Incentive Option granted under the Plan.

         The Company shall pay all issue or transfer taxes with respect to the
issuance of transfer of Shares, as well as all fees and expenses necessarily
incurred by the Company in connection with such issuance or transfer, except
fees and expenses which may be necessitated by the filing or amending of a
Registration Statement under the Securities Act, which fees and expenses shall
be borne by the recipient of the Shares unless such Registration Statement has
been filed by the Company for its own corporate purposes (and the Company so
states) in which event the recipient of the Shares shall bear only fees and
expenses as are attributable solely to the inclusion of the Shares he or she
received in the Registration Statement.

                                      -9-

<PAGE>   30

         All Shares issued as provided herein shall be fully paid and
non-assessable to the extent permitted by law.

         XVI.  WITHHOLDING TAXES

         The Company may require an employee exercising a Right or
Non-Qualified Option granted hereunder, or disposing of Shares acquired
pursuant to the exercise of an Incentive Option in a disqualifying disposition
(within the meaning of Section 421(b) of the Code), to reimburse the
corporation that employs such employee for any taxes required by any government
to be withheld or otherwise deducted and paid by such corporation in respect of
the issuance or disposition of such Shares. In lieu thereof, the corporation
that employs such employee shall have the right to withhold the amount of such
taxes from any other sums due or to become due from such corporation to the
employee upon such terms and conditions as the Committee shall prescribe. The
corporation that employs such employee may, in its discretion, hold the stock
certificate to which such employee is entitled upon the exercise of an Option
as security for the payment of such withholding tax liability, until cash
sufficient to pay that liability has been accumulated. In addition, at any time
that the Company becomes subject to a withholding obligation under applicable
law with respect to the exercise of a Right or Non-Qualified Option (the "Tax
Date"), except as set forth below, a holder of a Right or Non-Qualified Option
may elect to satisfy, in whole or in part, the holder's related personal tax
liabilities (an "Election") by (i) directing the Company to withhold from
Shares issuable in the related exercise either a specified number of Shares or
Shares having a specified value (in each case not in excess of the related
personal tax liabilities), (ii) tendering Shares previously issued pursuant to
the exercise of an Option or Right or other Shares of the Company's common
stock owned by the holder or (iii) combining any or all of the foregoing
options in any fashion. An Election shall be irrevocable. The withheld Shares
and other Shares tendered in payment shall be valued at their fair market value
(determined in accordance with the principles set forth in Article V of the
Plan) on the Tax Date. The Committee may disapprove of any Election, suspend or
terminate the right to make Elections or provide that the right to make
Elections shall not apply to particular Shares or exercises. The Committee may
prescribe additional rules, in its discretion, to permit a holder of an Option
or Right who is subject to the reporting requirements of Section 16(a) of the
Exchange Act to effect such tax withholding in compliance with the Rules
promulgated under Section 16 of the Exchange Act and the positions of the staff
of the Securities and Exchange Commission expressed in no-action or
interpretative letters exempting such tax withholding transactions from
liability under Section 16(b) of the Exchange Act.  The Committee may also
impose any additional conditions or restrictions on the right to make an
Election as it shall deem appropriate.

         XVII.  LISTING OF SHARES AND RELATED MATTERS

         The Committee may delay any award, issuance or delivery of Shares if
it determines that listing, registration or qualification of Shares or the
consent or approval of any governmental regulatory body is necessary or
desirable as a condition of, or in connection with, the sale or purchase of
Shares under the Plan, until such listing, registration, qualification, consent
or approval shall have been effected or obtained, or otherwise provided for,
free of any conditions not acceptable to the Committee.

         XVIII.  AMENDMENT OF THE PLAN

         The Board of Directors or the Committee, as the case may be, may, from
time to time, amend the Plan, provided that no amendment shall be made, without
the approval of the stockholders of the Company, that will (i) increase the
total number of Shares reserved for Options under the Plan (other than an
increase resulting from an adjustment provided for in Article XII), (ii) reduce
the exercise price of any Incentive Option granted hereunder below the price
required by Article V, (iii) modify the provisions of the Plan relating to
eligibility, or (iv) materially increase the benefits accruing to participants
under the Plan. The Board of Directors or the Committee, as the case may be,
shall be authorized to amend the Plan and the Options granted thereunder to
permit the Incentive Options granted thereunder to qualify as incentive stock
options within the meaning of Section 422 of the Code. The rights and
obligations under any Option or Right granted before amendment of the Plan or
any

                                      -10-

<PAGE>   31

unexercised portion of such Option or Right shall not be adversely affected by
amendment of the Plan, Option or Right without the consent of the holder of
such Option or Right.

`
         XIX.  TERMINATION OR SUSPENSION OF THE PLAN

         The Board of Directors may at any time suspend or terminate the Plan.
The Plan, unless sooner terminated by action of the Board of Directors, shall
terminate at the close of business on the Termination Date. Options and Rights
may not be granted while the Plan is suspended or after it is terminated.
Rights and obligations under any Option or Right granted while the Plan is in
effect shall not be altered or impaired by suspension or termination of the
Plan, except upon the consent of the person to whom the Option or Right was
granted.  The power of the Committee to construe and administer any Options or
Rights granted prior to the termination or suspension of the Plan under Article
III nevertheless shall continue after such termination or during such
suspension.

         XX.  GOVERNING LAW

         The Plan, such Options and Rights as may be granted thereunder and all
related matters shall be governed by, and construed and enforced in accordance
with, the laws of the State of Delaware from time to time obtaining.

         XXI.  PARTIAL INVALIDITY

         The invalidity or illegibility of any provision hereof shall not be
deemed to affect the validity of any other provision.

         XXII.  EFFECTIVE DATE

         This Plan became effective at 5:30 P.M., New York City Time, on the
Effective Date.
