                       PROXY STATEMENT FOR ANNUAL MEETING
                                OF STOCKHOLDERS

                                AUGUST 12, 2003

     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 Tuesday, August 12, 2003, at 12:30 p.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, 2003. A copy of the Company's Annual Report to Stockholders
for the fiscal year ended March 31, 2003 is being furnished with this proxy
statement.

     Only holders of the Common Stock of record as of the close of business on
Friday, June 13, 2003 are entitled to notice of and to vote at the Annual
Meeting and any adjournment thereof. On that date, 18,389,534 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 other 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
(although no revocation shall be effective until actual 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 for purposes of determining a quorum. At the
Annual Meeting, directors will be elected by a plurality vote and all other
matters will be decided by the affirmative vote of a majority of the votes cast.
Abstentions and broker non-votes are not votes cast and will not be included in
calculating the number of votes necessary for approval of the matter.

     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 AUTHORIZED UNDER THE 1992 COMPANY STOCK OPTION PLAN, FOR
APPROVAL OF AN INCREASE IN THE NUMBER OF SHARES AUTHORIZED UNDER THE 1992
DIRECTOR STOCK OPTION PLAN AND FOR RATIFICATION OF THE APPOINTMENT OF ERNST &
YOUNG LLP AS THE INDEPENDENT PUBLIC ACCOUNTANTS OF THE COMPANY FOR THE FISCAL
YEAR ENDING MARCH 31, 2004.


                             ANNUAL MEETING MATTERS

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 six (6) members. The Board of Directors has adopted a
resolution requiring that a majority of the Company's directors are required to
be independent under all applicable definitions of independence. At present, all
directors are independent under all currently applicable definitions of
independence, except for Fred C. Young as a result of his position as the
Company's Chief Executive Officer.

     All directors of the Company are elected each year. The Board has nominated
six (6) persons for election to the Board at the Annual Meeting. Therefore, six
(6) 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. The stockholders may fill any vacancy in the office of a director.
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 or until
his or her earlier death, resignation or removal. If the Board of Directors
increases the number of directors, the Board of Directors may fill any vacancy
so created.

     The holders of Common Stock have one vote for each share owned as of the
record date in the election of directors. The six (6) nominees receiving the
greatest number of affirmative votes will be elected as directors for terms
expiring in 2004.

     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 nominees of the Board of Directors, each of
whom presently serves as a director of the Company: William F. Andrews, Thomas
W. Golonski, Thomas G. Greig, William R. Newlin, Brian D. Young and Fred C.
Young (Brian D. Young and Fred C. Young are not related).

     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.

     WILLIAM F. ANDREWS, 71, was elected a director of the Company on May 18,
1992. He currently is Chairman of Corrections Corporation of America (private
prisons) and Chairman of Katy Industries. He was Chairman of Scovill Fasteners,
Inc. and Northwestern Steel and Wire from 1996 to 2001 and Chairman, President,
Chief Executive Officer and a director of Amdura Corporation from 1993 to 1995.
Prior to such time, Mr. Andrews was the President and Chief Executive Officer of
UNR Industries, Inc. from 1990 to 1992. He is also a director of Corrections
Corporation, Katy Industries and Trex Corporation.

11, 2003. Mr. Golonski is Chairman, President and Chief Executive Officer of
National City Bank of Pennsylvania and Executive Vice President of National City
Corporation since 1996. Mr. Golonski is also a director of several economic
development organizations and active in other charitable and financial
organizations.

     THOMAS G. GREIG, 55, was elected a director of the Company on August 10,
1999. Mr. Greig is a Managing Director of Liberty Capital Partners, a private
equity partnership, since 1998. From 1973 to 1998, Mr. Greig worked in the
investment banking industry, principally in the technology investment banking
area. Mr. Greig is a director of Rudolph Technologies, Inc. and a number of
privately held companies and a public, not-for-profit foundation.

                                        2


     WILLIAM R. NEWLIN, 62, was elected a director of the Company on December
18, 1995. He has served as Chairman and Chief Executive Officer of Buchanan
Ingersoll Professional Corporation (attorneys at law) since 1980. He also serves
as a Managing General Partner of CEO Venture Funds (private venture capital
funds). He is also Lead Director and Chairman of the Executive Committee of

Chief Financial Officer and Treasurer from 1991 until May 1997 and was Secretary
from 1991 until May 1999. He is also a director of Citizens Bank of
Pennsylvania.

     Brian D. Young and Fred C. Young are not related.

PROPOSAL 2 - APPROVAL OF INCREASE TO 1992 COMPANY STOCK OPTION PLAN

     In November 1992, the Board of Directors and stockholders adopted the
Employee Plan. The Employee Plan constitutes a key element of the Company's
total compensation program. This plan is designed to motivate key employees of
the Company to remain focused on long-term stockholder value performance.

     As a result of the prior grants of stock options under the Employee Plan,
the number of shares available for grant as of March 31, 2003 was 107,597. In
order to maintain the Company's pay-for-performance compensation philosophy, 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 600,000 shares. The aggregate
number of shares will increase from 6,850,000 to 7,450,000.

     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 retain key employees and motivate
       such employees to remain focused on long-term stockholder value
       performance.

     - Support the Company's strategy of using stock options as a key component
       of an employee's total compensation. The Company's philosophy is to be
       conservative with the cash component of total compensation and tie the
       at-risk variable portion to overall Company stock performance.

     - Generally, the Company does not have a Company-funded post-retirement
       medical benefits program or a defined contribution pension program for
       any of its key employees. The Employee Plan is also designed to cover the
       cost of these types of post-retirement benefits. This program design is
       consistent with the Company's overall philosophy of pay-for-performance.

     - Because the Company has actively repurchased its common stock (the
       Company repurchased 1.7 million shares during Fiscal 2003 and 3.8 million
       shares from program inception in April 1999 through March 31, 2003) it
       believes that the stock options as a percentage of total shares,
       including options, should be reviewed prior to the impact of any share
       repurchases. Currently, this percentage is 16.1% of the total shares.
       With the proposed increase, the percentage of shares of common stock
       including shares reserved for future grant will be 17.9% of the total
       shares, including options.

                                        3


     - As of March 31, 2003, 66% of the total outstanding options granted to
       current employees were vested. Consequently, the Board believes that the
       key employees continue to retain their options as they are personally
       committed to the Company's long-term profit goals and subsequent
       opportunity for stock appreciation, thereby aligning their financial
       goals with those of the stockholders. Because of the retention of vested
       options, the calculated shares outstanding attributable to the Employee
       Plan is higher than if employees were to have exercised and sold such
       options.

     For the above stated reasons, the Board believes that the proposed increase
is appropriate.

     The affirmative vote of a majority of the votes cast in person or by proxy
at the meeting is required to approve the amendment to the Employee Plan.

     Because one of the executive officers, as a member of the Board of
Directors, is eligible to receive awards under the Employee Plan, he 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.

PROPOSAL 3 - APPROVAL OF INCREASE TO 1992 DIRECTOR STOCK OPTION PLAN

     In November 1992, the Board of Directors and stockholders adopted the
Director Plan. The Director Plan constitutes a key element of the Company's
incentive program that is utilized to attract and retain the services of persons
capable of filling director positions of the Company.

     As a result of the prior grants of stock options under the Director Plan,
the number of shares currently available for grant as of March 31, 2003 was
25,883. In order to maintain the Company's incentive plan to attract and retain
directors, the Board has adopted and proposes that the stockholders approve an
amendment to the Director Plan which will increase the total number of shares
available for the grant of stock options under the Director Plan by 20,000
shares. The aggregate number of shares will increase from 190,000 to 210,000.

     The Board believes the increase in the number of shares available for
issuance under the Director Plan will:

     - Maintain the Company's ability to attract and retain directors capable of
       filling such position.

     - Support the Company's philosophy of using at-risk, variable compensation
       as a key component of a director's total compensation. This enables the
       Company to remain conservative relative to the fixed fees paid to
       directors.

     The affirmative vote of a majority of the votes cast in person or proxy at
the meeting is required to approve the amendment to the Director Plan.

     Because non-employee Directors are eligible to receive awards under the
Director 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 3.

PROPOSAL 4 - RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     In May 2003, the Board of Directors, upon recommendation of the Audit
Committee, appointed Ernst & Young LLP as the independent public accountants of
the Company for the fiscal year ending March 31, 2004. The affirmative vote of a
majority of the votes cast in person or by proxy at the meeting is required for
the ratification by the Company's stockholders of such appointment.

     Unless otherwise directed by the stockholders, proxies will be voted for
the ratification of the appointment of Ernst & Young LLP as independent public
accountants of the Company for the fiscal year ending March 31, 2004. A
representative of Ernst & Young LLP is expected to be present at the Annual
Meeting, will not be making a statement but will be available to respond to
appropriate questions.
                                        4


     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR APPROVAL OF PROPOSAL 4.

                BOARD OF DIRECTORS AND CERTAIN BOARD COMMITTEES

     The Company's Board of Directors held four meetings during the fiscal year
ended March 31, 2003 ("Fiscal 2003"). During Fiscal 2003, each director attended
at least 75% of the meetings of the board and each committee on which such
director served.

     During Fiscal 2003, directors who were not employees of the Company
received directors' fees of $7,500 per annum, paid quarterly, and an additional
fee of $375 for each meeting of the Board of Directors attended in person. In
addition, the Company maintains directors' and officers' liability insurance.

AUDIT COMMITTEE

     The Board has an Audit Committee consisting of William F. Andrews as chair,
Thomas G. Greig and Brian D. Young. Each member of the Audit Committee is
independent under Nasdaq's listing standards. The Audit Committee's duties
include recommending to the Board of Directors the appointment of the
independent auditors of the Company, reviewing with the independent auditors
their report as well as any recommendations with respect to the Company's
accounting policies, procedures and internal controls. In addition, this
committee is charged with reviewing the independent auditor's fees for audit and
non-audit services, and determining whether there are any conflicts of interest
in financial or business matters between the Company and any of its officers or
employees. The Audit Committee was scheduled to meet, and did meet, twice in
Fiscal 2003. A copy of the Board's Audit Committee Charter is attached to this
Proxy Statement as Annex A.

COMPENSATION COMMITTEE

     The Board has a Compensation Committee, consisting of Brian D. Young as
chair, William F. Andrews and Thomas G. Greig. The Compensation Committee is
responsible for reviewing and approving the total compensation of the executive
officers of the Company. In addition, the Committee reviews the overall
compensation philosophy for all team members. The Compensation Committee was
scheduled to meet, and did meet, twice in Fiscal 2003.

NOMINATING COMMITTEE

     The Company has a standing Nominating Committee consisting of Thomas G.
Greig as chair, William R. Newlin and Brian D. Young. The Nominating Committee
considers and recommends to the Board of Directors nominees to serve as
directors of the Company, including nominees proposed by the Company's
stockholders.

     The Nominating Committee considers the total breadth and experience of
potential nominees. Potential Board members should show a willingness to fully
participate in Board meetings, a proven track record of career accomplishments,
the ability to make sound judgments and the ability to motivate and guide
management.

     Stockholder proposals for nominees are to be in accordance with the
Company's Certificate of Incorporation, By-laws and other applicable laws,
including the rules and regulations of the Securities and Exchange Commission
and any stock market on which the Company's stock is listed for trading or
quotation. Generally, such recommendations made by a stockholder entitled to
notice of, and to vote at, the meeting at which such proposed nominee is to be
considered, are written, and are received by the Secretary of the Company within
a prescribed time period prior to the annual or special meeting. A copy of the
By-laws is available from the Company upon request.

     As the Nominating Committee was formed in May of Fiscal 2003, it was
scheduled to meet, and did meet, once in Fiscal 2003. In the future, the
Committee is scheduled to meet twice a year.

                                        5


GOVERNANCE COMMITTEE

     The Company has a Governance Committee, consisting of William R. Newlin as
chair, Thomas G. Greig and Brian D. Young. The Governance Committee is
responsible to oversee the Company's continued dedication to the practice of
sound corporate governance. The Committee also monitors trends and best
practices in corporate governance.

     As the Governance Committee was formed in May of Fiscal 2003, it was
scheduled to meet, and did meet, once in Fiscal 2003. In the future, the
Committee is scheduled to meet twice a year.

                      REPORT OF THE COMPENSATION COMMITTEE

MEMBERSHIP AND ROLE OF COMPENSATION COMMITTEE

     The Compensation Committee of the Board of Directors consisted of Brian D.
Young as chair, William F. Andrews and Thomas G. Greig. The Compensation
Committee is charged with administering the Company's compensation programs for
executive officers, including fixed compensation and incentive compensation
plans, including the Company's stock option plans. 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 and the Compensation
Committee seek to:

     - 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 a pay-for-performance philosophy in the form of
       fixed and at risk, variable compensation.

ANNUAL EXECUTIVE COMPENSATION

     The annual 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 success. The Company and the
Compensation Committee believe that the annual compensation paid to the
Company's executives has historically been competitive with that paid to
executives in the industry. In making compensation decisions, the Company has
relied upon its Board of Directors and the Compensation Committee's collective
knowledge of the industry and the functions that Company executives perform.

     The primary goals for executives, in their own respective positions, are to
help the Company achieve its annual profit and cash flow targets. Fixed salaries
for the executives are reviewed by the Compensation

                                        9


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. In making its decision, the Compensation Committee
will also consider the amount of each executive's overall compensation, which is
in the form of base salary versus compensation that is at-risk.

     Included in total compensation is at-risk incentive compensation.
Generally, the incentive compensation payments are made as a percentage of fixed
salaries. Any payments are subject to approval by the Board of Directors on an
annual basis.

COMPANY STOCK OPTION PLAN

     In Fiscal 1993, the Company's Board of Directors and stockholders approved
the Employee Plan, pursuant to which the Compensation Committee may grant stock
options to key employees, including those who may be executive officers of the
Company. This plan was amended in Fiscal 1995 through Fiscal 2003 pursuant to
stockholder votes 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 2003 is set forth in the table entitled "Option
Grants in Last Fiscal Year" appearing elsewhere in this proxy statement. The
Compensation 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.

     The Employee Plan requires that all options have an exercise price of not
less than the fair market value of the stock on the date of grant of the option.

CHIEF EXECUTIVE OFFICER'S COMPENSATION ANALYSIS

     In determining the total compensation for Fred C. Young, the Chairman and
CEO of the Company, the Compensation Committee used the same criteria described
above in the opening paragraphs of the Annual Executive Compensation section.

     The Compensation Committee believes that the total compensation for Mr.
Young was appropriate for Fiscal 2003 because of the overall performance of the
Company, his individual performance and comparable executive compensation in the
industry.

SUMMARY

     The Company's total compensation plan is predicated on the Committee and
the Company's belief that executives contribute to stockholder returns by
maximizing profits and cash flow.

     The Committee believes that the total compensation paid to its executives
for Fiscal 2003 was reasonable in view of the Company's performance relative to
the overall industry.

            REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

     The following is the report of the Audit Committee with respect to the
Company's audited financial statements for the fiscal year ended March 31, 2003,
included in the Company's Annual Report on Form 10-K. The information contained
in this report shall not be deemed to be "soliciting material" or to be "filed"
with the Securities and Exchange Commission, nor shall such information be
incorporated by reference into any future filing under the Securities Act of

the extent that the Company specifically incorporates it by reference in such
filing.

MEMBERSHIP AND ROLE OF AUDIT COMMITTEE

     During Fiscal 2003, the Audit Committee consisted of the following members
of the Company's Board of Directors: William F. Andrews, as chair, Thomas G.
Greig and Brian D. Young. Each of the members of the Audit Committee is
independent as defined under Nasdaq's listing standards. The Audit Committee
operates under a written charter adopted by the Board of Directors.

REVIEW WITH MANAGEMENT

     The Audit Committee has reviewed and discussed the Company's audited
financial statements with management.

REVIEW AND DISCUSSIONS WITH INDEPENDENT ACCOUNTANTS

     The Audit Committee has discussed with Ernst & Young LLP, the Company's
independent accountants for Fiscal 2003, the matters required to be discussed by
SAS 61 (Codification of Statements on Accounting Standards) which includes,
among other items, matters related to the conduct of the audit of the Company's
financial statements.

     The Audit Committee has also received written disclosures and the letter
from Ernst & Young LLP required by Independence Standards Board Standards No. 1
(which relates to the accountant's independence from the Company and its related
entities) and has discussed with Ernst & Young LLP their independence from the
Company.

CONCLUSION

     Based on review and discussions referred to above, the Committee
recommended to the Company's Board that the Company's audited financial
statements be included in the Company's Annual Report on Form 10-K for the
fiscal year ended March 31, 2003.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     From February 1989 until January 1992, Brian D. Young, a current member of
the Compensation Committee, was a partner in Odyssey Partners, at that time the
Company's controlling stockholder, and served as President of MB Holdings, Inc.
MB Holdings, of which the Company is a successor, was at that time the holding
company for MICOM Communications Corp. and its subsidiaries as well as Black Box
Corporation and its subsidiaries. Each of MICOM and Black Box had separate
management teams responsible for the operating performance of that entity who
reported to the holding company management on behalf of its investors.
Subsequent to January 1992, the Company effected its initial public offering and
spun-off MICOM. While, technically, Brian D. Young was the President of the
predecessor to the Company, he did not have day-to-day management over the
operating companies, including Black Box. In addition, Brian D. Young and Fred
C. Young, the current Chairman and Chief Executive Officer, are not related to
each other.

                   SUMMARY OF 1992 COMPANY STOCK OPTION PLAN

     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. The
description set forth below does not include any of the proposed amendments to
the plan being voted on at the meeting.

     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 "Committee"). The
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 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 or hourly employee who is not a member of
the Committee may be granted Incentive Stock Options, Non-Qualified Stock
Options or Rights under the Employee Plan until November 30, 2012.

     EXERCISE PRICE.  The 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"), or in the case of a Non-Qualified Stock Option, 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; and (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.

     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 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 Compensation Committee and to the extent not
previously exercised, shall terminate and become null and void, provided that:
(i) if the employee shall die (a) while in the employ of the Company or (b)
within three (3) months of retirement from such employment or (c) 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
                                        16


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 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).

     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 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 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 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 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 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, 2012.

                        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.

                                        17


     NON-QUALIFIED STOCK OPTIONS.  Some options to be issued under the Employee
Plan will be designated as Non-Qualified Stock Options. If (as in the case of
Non-Qualified Stock Options granted under the Employee Plan at this time) the
Non-Qualified Stock Option does not have a "readily ascertainable fair market
value" at the time of the grant, the Non-Qualified Stock Option is not included
as compensation income at the time of grant. Rather, the optionee realizes
compensation income only when the Non-Qualified Stock Option is exercised and
the optionee has become substantially vested in the shares transferred. The
shares are considered to be substantially vested when they are either
transferable or not subject to a substantial risk of forfeiture. The amount of
income realized is equal to the excess of the fair market value of the shares at
the time the shares become substantially vested over the sum of the exercise
price plus the amount, if any, paid by the optionee for the Non-Qualified Stock
Option.

     If a Non-Qualified Stock Option is exercised through payment of the
exercise price by the delivery of common stock, to the extent that the number of
shares received by the optionee exceeds the number of shares surrendered,
ordinary income will be realized by the optionee at that time only in the amount
of the fair market value of such excess shares, and the tax basis of such excess
shares will be such fair market value.

     Generally, the optionee's basis in the shares will be the exercise price
plus the compensation income realized at the time of exercise and the amount, if
any, paid by the optionee for the Non-Qualified Stock Option. The capital gain
or loss will be short-term if the shares are disposed of within one year after
the option is exercised; such short-term gains are taxable as ordinary income.
If the shares were held more than 12 months as of the sale date, the gain is
taxable as a long-term capital gain at a maximum rate of 15%.

     If a Non-Qualified Stock Option expires without being exercised, the
optionee will have no tax consequences unless the optionee paid for the
Non-Qualified Stock Option. In such case, the optionee would recognize a loss in
the amount of the price paid by the optionee for the Non-Qualified Stock Option.

     The Company is generally entitled to a deductible compensation expense in
an amount equivalent to the amount included as compensation income to the
optionee. This deduction is allowed in the Company's taxable year in which the
income is included as compensation to the optionee.

     The preceding discussion is based upon federal tax laws and regulations in
effect on the date of this Proxy Statement, which are subject to change, and
upon an interpretation of the relevant sections of the Code, their legislative
histories and the income tax regulations that interpret similar provisions of
the Code. Furthermore, the foregoing is only a general discussion of the federal
income tax aspects of the Employee Plan and does not purport to be a complete
description of all federal income tax aspects of the Employee Plan. Optionees
may also be subject to state and local taxes in connection with the grant or
exercise of options granted under the Employee Plan and the sale or other
disposition of shares acquired upon the exercise of the options. Each employee
receiving a grant of options should consult with his or her personal tax advisor
regarding the federal, state and local tax consequences of participating in the
Employee Plan.

     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 Non-Qualified 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 that the holder of the Right realizes as
ordinary income.

     INCENTIVE STOCK OPTIONS.  Some options to be issued under the Employee Plan
will be designated as Incentive Stock Options and are intended to qualify under
Section 422 of the Code. Under the provisions of
                                        18


Section 422 and the related regulations, 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 is 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. The taxation of gain or loss upon the sale of stock acquired upon exercise
of an Incentive Stock Option depends in part on whether the stock is held for at
least two years from the date the option was granted and at least one year from
after the date the stock was transferred to the optionee (the "ISO Holding
Period").

     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 capital gain (see
below). If the optionee disposes of the shares in a disqualifying disposition at
a price that is below the fair market value of the shares at the time the
Incentive Stock Option was exercised and such disposition is a sale or exchange
to an unrelated party, the amount includable as compensation income to the
optionee will be limited to the excess of the amount received on the sale or
exchange over the exercise price.

     If the optionee recognizes ordinary income upon a disqualifying
disposition, the Company generally will be entitled to a tax deduction in the
same amount.

     If the ISO Holding Period is met, the gain is taxable as a long-term
capital gain at a maximum rate of 15%.

     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 transferred shares
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. If an Incentive Stock Option is exercised through the payment of
the exercise price by the delivery of common stock, to the extent that the
number of shares received exceeds the number of shares surrendered, such excess
shares will be considered Incentive Stock Option stock with a zero basis.

                   SUMMARY OF 1992 DIRECTOR STOCK OPTION PLAN

     The following is a summary description of the Director Plan, is not a
complete statement of the Director Plan and is qualified in its entirety by
reference to the complete text of the Director Plan, a copy of which is
available form the Company upon request. The description set forth below does
not include any of the proposed amendments to the plan being voted on at the
meeting.

     ADMINISTRATION.  The Director Plan is administered by the Board or 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 "Plan
Administrator"). The Plan Administrator, from time to time at its discretion,
makes determinations with respect to the persons who shall be granted Options or
Rights, and the number of shares of the Common Stock that may be purchased
pursuant to such Options or Rights. The interpretation and construction by the
Plan Administrator of any provisions of the Director Plan or of an Option or
Right granted thereunder is binding and conclusive on all optionees and on their
legal representatives and beneficiaries.

     TYPES OF OPTIONS.  The Options granted under the Director Plan will be
Non-Qualified Stock Options under the Code.

     RIGHTS.  The Plan Administrator, in its discretion, may grant Rights either
alone, simultaneously with the grant of an Option and in conjunction with the
grant of an Option and in conjunction therewith, or subsequent to the grant of
an Option and in conjunction therewith or in the alternative thereto.

                                        19


     ELIGIBILITY.  Any non-employee director may be granted Options or Rights
under the Director Plan until November 30, 2012.

     EXERCISE PRICE.  The Plan Administrator shall determine the exercise price
for each Option or Right granted under the Director Plan; provided however, that
the exercise price shall not be less than 100% of the fair market value on the
date of grant of the shares to which the Option or Right relates.

     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 Plan Administrator and set forth
in the grantee's agreement. Options are not transferable by the optionee except
by will or by the laws of descent and distribution.

     TERMINATION; DISABILITY; DEATH.  Upon cessation of such person's status as
a director, an Option or Right previously granted to the director, unless
otherwise specified by the Plan Administrator and to the extent not previously
exercised, shall terminate and become null and void, provided that: (i) if the
director shall die while in the employ of the Company or within three (3) months
of retirement or within one (1) year of retirement by reason of disability, the
legal representative or heirs of such director 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 removal other than for cause (as defined
in the Director Plan), then such director 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 removal other than for
cause and (b) one (1) year after termination by reason of disability. If a
director voluntarily terminates his service or is terminated for cause, any
Option or Right, unless otherwise specified by the Plan Administrator, 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 while 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).

     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 Plan Administrator 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 Plan
Administrator shall make any further adjustment as may be appropriate to the
maximum number of shares which may be acquired under the Director Plan pursuant
to the exercise of Options and Rights, the maximum number of shares which may be
so acquired by one director 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 Plan Administrator as to these matters shall be conclusive.

     In the event of a "change in control" of the Company, as defined in the
Director Plan, all then outstanding Options and Rights shall immediately become
exercisable. The Plan Administrator, in its discretion, may determine that, upon
the occurrence of a change in control transaction, each Option or Right
outstanding under the Director 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 of the Plan Administrator, as the case may be, may,
from time to time, amend the Director 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 Director Plan
(other than an increase resulting from an adjustment of outstanding Common
Stock), (ii) reduce the exercise price of any Option granted under the Director
Plan below the price required by the Director Plan, (iii) modify the provisions
of the Director Plan relating to eligibility, or (iv) materially increase the
benefits

                                        20


accruing to participants under the Director Plan. The rights and obligations
under any Option or Right granted before amendment of the Director Plan or any
unexercised portion of such Option or Right shall not be adversely affected by
amendment of the Director 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 Director Plan.

     TERM OF PLAN.  Options and Rights may be granted under the Director Plan
until November 30, 2012.

                        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 Director Plan is not subject to the protective provisions of
the Employee Retirement Security Act of 1974 and is not qualified under Section
401(a) of the Code.

     An option to be issued under the Director Plan will be designated as a
Non-Qualified Stock Option. If (as in the case of a Non-Qualified Stock Option
granted under the Director Plan at this time) the Non-Qualified Stock Option
does not have a "readily ascertainable fair market value" at the time of the
grant, the Non-Qualified Stock Option is not included as compensation income at
the time of grant. Rather, the optionee realizes compensation income only when
the Non-Qualified Stock Option is exercised and the optionee has become
substantially vested in the shares transferred. The shares are considered to be
substantially vested when they are either transferable or not subject to a
substantial risk of forfeiture. The amount of income realized is equal to the
excess of the fair market value of the shares at the time the shares become
substantially vested over the sum of the exercise price plus the amount, if any,
paid by the optionee for the Non-Qualified Stock Option.

     If a Non-Qualified Stock Option is exercised through payment of the
exercise price by the delivery of common stock, to the extent that the number of
shares received by the optionee exceeds the number of shares surrendered,
ordinary income will be realized by the optionee at that time only in the amount
of the fair market value of such excess shares, and the tax basis of such excess
shares will be such fair market value.

     Generally, the optionee's basis in the shares will be the exercise price
plus the compensation income realized at the time of exercise and the amount, if
any, paid by the optionee for the Non-Qualified Stock Option. The capital gain
or loss will be short-term if the shares are disposed of within one year after
the option is exercised; such short-term gains are taxable as ordinary income.
If the shares were held more than 12 months as of the sale date, the gain is
taxable as a long-term capital gain at a maximum rate of 15%.

     If a Non-Qualified Stock Option expires without being exercised, the
optionee will have no tax consequences unless the optionee paid for the
Non-Qualified Stock Option. In such case, the optionee would recognize a loss in
the amount of the price paid by the optionee for the Non-Qualified Stock Option.

     The Company is generally entitled to a deductible compensation expense in
an amount equivalent to the amount included as compensation income to the
optionee. This deduction is allowed in the Company's taxable year in which the
income is included as compensation to the optionee.

     The preceding discussion is based on federal tax laws and regulations in
effect on the date of this Proxy Statement, which are subject to change, and
upon an interpretation of the relevant sections of the Code, their legislative
histories and the income tax regulations that interpret similar provisions of
the Code. Furthermore, the foregoing is only a general discussion of the federal
income tax aspects of the Director Plan. Optionees may also be subject to state
and local taxes in connection with the grant or exercise of options granted
under the Director Plan and the sale or other disposition of shares acquired
upon exercise of the options. Each director receiving a grant of options should
consult with his or her personal tax advisor regarding the federal, state and
local tax consequences of participating in the Director Plan.

     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

                                        21


because of this limitation may 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 Non-Qualified 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 that the holder of the Right realizes as
ordinary income.

                          DISMISSAL OF ARTHUR ANDERSEN

     As previously discussed on a Form 8-K filed with the SEC on June 24, 2002
(the "Company's Form 8-K"), the Company dismissed Arthur Andersen LLP ("Arthur
Andersen") as the Company's independent public accountants and engaged Ernst &
Young LLP ("E&Y") to serve as the Company's independent public accountants for
the fiscal year ending March 31, 2003. This determination was approved by the
Company's Board of Directors upon the recommendation of its Audit Committee.

     Arthur Andersen's reports on the Company's consolidated financial
statements for each of the fiscal years ended March 31, 2002 and 2001 did not
contain an adverse opinion or disclaimer of opinion. The March 31, 2002 report
contained an explanatory fourth paragraph disclosing the Company's change in its
method of accounting for goodwill and other intangible assets. The March 31,
2001 and 2000 reports were not qualified or modified as to uncertainty, audit
scope or accounting principles.

     During the fiscal years ended March 31, 2002 and 2001 and through June 24,
2002, there were no disagreements with Arthur Andersen on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure which, if not resolved to Arthur Andersen's satisfaction,
would have caused them to make reference to the subject matter in connection
with their report on the Company's consolidated financial statements for such
years; and there were no reportable events as defined in Item 304(a)(1)(v) of
Regulation S-K.

     The Company has provided Arthur Andersen with a copy of the above
statements. Attached as Exhibit 16 to the Company's Form 8-K is a copy of a
letter from Arthur Andersen stating it found no basis for disagreement with such
statements.

     During the fiscal years ended March 31, 2002 and 2001 and through the date
of the Board's decision, the Company did not consult with E&Y with respect to
the application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's consolidated financial statements, or any other matters or
reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

                    ERNST & YOUNG AS INDEPENDENT ACCOUNTANTS

FEES BILLED TO THE COMPANY BY ERNST & YOUNG LLP DURING FISCAL 2003

     AUDIT FEES:  An aggregate of $548,700 was billed for professional services
and expenses rendered for the audit of the Company's annual financial statements
for Fiscal 2003 and for the reviews of financial statements included in the
Company's quarterly reports on Form 10-Q for Fiscal 2003.

     AUDIT RELATED SERVICES FEES:  $12,800 in fees were billed for audits of
employee benefit plans during Fiscal 2003.

     TAX SERVICES FEES:  $86,200 in fees were billed for tax compliance,
planning and advice during Fiscal 2003.

                                        22


     FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES:  Ernst &
Young LLP did not render professional services to the Company relating to
financial information systems design and implementation during Fiscal 2003.

     Ernst & Young LLP did not receive any other fees during Fiscal 2003.

     The Audit Committee considered whether the provision of non-audit services
rendered by Ernst & Young LLP to the Company was compatible with maintaining
Ernst & Young LLP's independence and determined that they would be compatible.
All non-audit services performed by Ernst & Young LLP are subject to pre-
approval by the Audit Committee.

       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, 2003, 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, Director of Compliance, Black Box
Corporation, 1000 Park Drive, Lawrence, Pennsylvania 15055.

                            SOLICITATION OF PROXIES

     The Company will pay the expenses in connection with the printing,
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, directors, officers or regular employees of the Company
may solicit proxies 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.

                     STOCKHOLDER NOMINATIONS AND PROPOSALS

     Stockholders who believe they are eligible to have their proposals included
in the Company's proxy statement for the annual meeting expected to be held in
August 2004, in addition to other applicable requirements established by the
SEC, must ensure that their proposals are received by the Secretary of the
Company not later than March 5, 2004.

     The By-laws of the Company establish an advance notice procedure for
eligible Stockholders to make nominations for director and to propose business
to be transacted at an annual meeting. The Company's By-laws provide that
nominations for director and proposals for business must be given to the
Secretary of the Company not later than 150 days prior to the anniversary date
of the prior year's annual meeting. For the Annual Meeting expected to be held
in August 2004, nominations and proposals under this provision must be received
by March 15, 2004. The Company's By-laws also require that certain specific
information accompany a stockholder notice of nomination or proposal for
business. The Company's By-laws, however, do not limit or restrict the ability
of a stockholder to present any proposal made by such stockholder in accordance
with SEC requirements. A copy of the Company's By-laws is available from the
Company upon request.

                                 OTHER MATTERS

     Management does not intend to present, nor, in accordance with the
Company's By-laws, has it received proper notice from any person who intends to
present, any matter for action by stockholders at the Annual Meeting to be held
on August 12, 2003, other than as stated in the Notice of Annual Meeting of
Stockholders accompanying this Proxy Statement. The enclosed proxy, however,
confers discretionary authority with respect to the transaction of any other
business that properly may come before the meeting, and it is the intention of
the persons named in the enclosed proxy to vote on any such matters in
accordance with their best judgment.
