                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)
                (Dollars in thousands, except per share amounts)

NOTE 1: BASIS OF PRESENTATION

The consolidated financial statements presented herein and these notes are
unaudited. Certain information and footnote disclosures normally included in the
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to the rules and regulations
of the Securities and Exchange Commission ("SEC"). Black Box Corporation (the
"Company") believes that these financial statements reflect all adjustments of a
normal, recurring nature necessary for a fair presentation of the results for
the interim periods presented. Interim periods are not necessarily indicative of
the results of operations for a full year. As such, these unaudited financial
statements should be read in conjunction with the audited financial statements
and notes thereto included in the Company's most recent Form 10-K as filed with
the SEC for the fiscal year ended March 31, 2003. The consolidated Balance Sheet
as of March 31, 2003 was derived from the audited Balance Sheet included in the
most recent Form 10-K.

NOTE 2: FISCAL YEARS AND BASIS OF PRESENTATION

The Company's fiscal year ends on March 31. Its fiscal quarters consist of 13
weeks and, beginning in Fiscal 2003, end on the Sunday nearest each calendar
quarter end. The actual ending date for the periods presented as September 30,
2003 and 2002 was September 28, 2003 and September 29, 2002, respectively. The
ending dates for all other periods are as presented.

NOTE 3: STOCK-BASED COMPENSATION

On December 31, 2002, the Financial Accounting Standards Board issued SFAS No.
148 "Accounting for Stock-Based Compensation - Transition and Disclosure." SFAS
No. 148 amends FASB Statement No. 123 "Accounting for Stock-Based Compensation,"
to provide alternative methods of transition to Statement No. 123's fair value
method of accounting for stock-based employee compensation. SFAS No. 148 also
amends the disclosure provisions of Statement 123 and APB Opinion No. 28
"Interim Financial Reporting," to require disclosure in the summary of
significant accounting policies of the effects of an entity's accounting policy
with respect to stock-based employee compensation on reported net income and
earnings per share in annual and interim financial statements. While the
statement does not amend Statement 123 to require companies to account for
employee stock options using the fair value method, the disclosure provisions of
SFAS No. 148 are applicable to all companies with stock-based employee
compensation, regardless of whether they account for that compensation using the
fair value method of Statement 123 or the intrinsic value method of Opinion No.
25. The Company continues to apply Opinion No. 25 in accounting for stock-based
compensation. SFAS No. 148 amendments of the transition and annual disclosure
requirements of Statement 123 are effective for fiscal years ending after
December 15, 2002.

Had the Company elected to recognize compensation cost based on the fair value
basis under SFAS No. 123, the Company's net income and earnings per share would
have been reduced to the pro forma amounts as follows:

NOTE 5: FINANCIAL DERIVATIVES

The Company has entered and will continue in the future, on a selective basis,
to enter into forward exchange contracts to reduce the foreign currency exposure
related to certain intercompany transactions. On a monthly basis, the open
contracts are revalued to fair market value, and the resulting gains and losses
are recorded in accumulated other comprehensive income. These gains and losses
offset the revaluation of the related foreign currency denominated receivables
and payables, which are also included in accumulated other comprehensive income.

At September 30, 2003, the open foreign exchange contracts were in Euro, Pound
sterling, Canadian dollars, Swiss francs, Japanese yen, Swedish krona and
Australian dollars. The total open contracts, with a notional amount of
approximately $13,427, have a fair value of $13,728 and will expire within six
months. The open contracts have contract rates of 0.8705 to 0.9023 Euro, 0.6138
to 0.634 Pound sterling, 1.3558 to 1.4121 Canadian dollars, 1.3237 to 1.3488
Swiss francs, 111.99 to 118.36 Japanese yen, 8.0248 to 8.4025 Swedish krona and
1.4736 to 1.5571 Australian dollars, all per U.S. dollar.

NOTE 7: EARNINGS PER SHARE

Basic earnings per common share were computed based on the weighted average
number of common shares issued and outstanding during the relevant periods.
Diluted earnings per common share were computed based on the weighted average
number of common shares issued and outstanding, plus the dilutive effect of
options (using the treasury stock method) and contingently issuable shares. The
following table details this calculation:

The Company also has 937,669 shares and 2,243,000 shares issuable upon the
exercise of outstanding stock options for the three months ended September 30,
2003 and 2002, respectively, and 2,401,343 shares and 1,423,000 shares for the
six months ended September 30, 2003 and 2002, respectively. The exercise price
of such options was greater than the average market price for those time periods
and as such do not impact the share count.

NOTE 8: NEW ACCOUNTING STANDARDS

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" ("FIN 46"). A variable interest entity ("VIE") is
one where the contractual or ownership interests in an entity change with
changes in the entity's net asset value. This interpretation requires the
consolidation of a VIE by the primary beneficiary, and also requires disclosure
about VIEs where an enterprise has a significant variable interest but is not
the primary beneficiary. The Company does not believe that this statement will
have a material impact on the Company's consolidated financial statements or
results of operations.

                (Dollars in thousands, except per share amounts)

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities." SFAS No. 149 amends and
clarifies financial accounting and reporting for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as derivatives) and for hedging activities under SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS
No. 149 is effective for contracts entered into or modified after June 30, 2003,
except in certain instances, and for hedging relationships designated after June
30, 2003. In addition, except in certain instances, all provisions of this
Statement should be applied prospectively. The application of SFAS No. 149 did
not have a material effect on the Company's consolidated financial statements or
results of operations.

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity." The provisions
of SFAS No. 150 require issuers to classify as liabilities, or assets in some
circumstances, certain classes of freestanding financial instruments that embody
obligations for the issuer. The provisions of SFAS No. 150 are effective for
financial instruments entered into or modified after May 31, 2003, and otherwise
shall be effective at the beginning of the first interim period beginning after
December 15, 2003. The adoption of SFAS No. 150 is not expected to have a
material effect on the Company's consolidated financial statements or results of
operations.

NOTE 9: CHANGES IN BUSINESS

During the six months ended September 30, 2003, the Company paid approximately
$425 for obligations related to mergers completed in prior periods.

During Fiscal 2003, the Company successfully completed three business
combinations that have been accounted for using the purchase method of
accounting, June 2002 - Societe d'Installation de Reseaux Informatiques et
Electriques; July 2002 - EDC Communications Limited and EDC Communications
(Ireland) Limited; and January 2003 - Rowe Structured Cabling Ltd. The aggregate
purchase price of these three business combinations was approximately $4,600 and
resulted in goodwill of $3,317 and other intangibles of $348 in accordance with
SFAS No. 141, "Business Combinations."

As of September 30, 2003, certain merger agreements provide for contingent
payments of up to $2,891. Upon meeting future operating performance goals,
goodwill will be adjusted for the amount of the contingent payments.

NOTE 10: INTANGIBLE ASSETS

On April 1, 2001, the Company adopted SFAS No. 142, "Goodwill and Other
Intangible Assets," under which goodwill and other intangible assets with
indefinite lives are not amortized. Such intangibles were evaluated for
impairment as of April 1, 2001 by comparing the fair value of each reporting
unit to its carrying value, and no impairment existed. In addition, during the
third quarter of Fiscal 2002 and Fiscal 2003, the Company conducted its annual
impairment analysis

                                       10

                (Dollars in thousands, except per share amounts)

and no impairment existed. During the third quarter of each future fiscal year,
the Company will evaluate the intangible assets for impairment with any
resulting impairment reflected as an operating expense. The Company's only
intangibles as identified in SFAS No. 141 other than goodwill, are its
trademarks, non-compete agreements and acquired backlog. During the fourth
quarter of Fiscal 2003, the Company changed its reportable segments and in
accordance with SFAS No. 142, evaluated its intangibles for impairment and none
existed.

As of September 30, 2003, the Company's trademarks had a net carrying amount of
$27,739. The Company believes this intangible has an indefinite life.

The Company had the following other intangibles as of September 30, 2003:

=============================================================================================


The non-compete agreements and acquired backlog are amortized over their
estimated useful lives of 10 years and 1 year, respectively. Amortization
expense for the non-compete agreements and acquired backlog intangibles during
the three and six months ended September 30, 2003 was $45 and $134,
respectively.

The estimated amortization expense for each of the five fiscal years subsequent
to September 30, 2003 for the non-compete agreements and acquired backlog
intangibles is as follows: remainder of fiscal 2004 - $94; fiscal 2005 - $186;
fiscal 2006 - $186; fiscal 2007 - $186; and fiscal 2008 - $186.

The changes in the carrying amount of goodwill, net of amortization, by
reporting segment for the six months ended September 30, 2003, are as follows:

NOTE 11: TREASURY STOCK

The Company previously announced intentions to repurchase up to 5.5 million
shares of its Common Stock from April 1, 1999 through September 30, 2003. During
the second quarter of Fiscal 2004, the Company repurchased approximately 0.4
million shares for an aggregate purchase price of $17,402 and for the first six
months of Fiscal 2004, repurchases totaled 0.8 million shares for $31,961. Since
inception of the repurchase program in April 1999 through September 2003, the
Company has repurchased in aggregate approximately 4.3 million shares for
approximately $196,000. Funding for the stock repurchases came from existing
cash flow and cash on hand. During the first half of the fiscal year, the
Company used $4,719 of cash on hand for stock repurchases.

Additional repurchases of stock may occur from time to time depending upon
factors such as the Company's cash flows and general market conditions. While
the Company expects to continue to repurchase shares for the foreseeable future,
there can be no assurance as to the timing or amount of such repurchases.

On April 4, 2000, Black Box Corporation of PA, a domestic subsidiary of the
Company, entered into a $120,000 Revolving Credit Agreement ("Long Term
Revolver") and a $60,000 Short Term Credit Agreement ("Short Term Revolver")

NOTE 14: SEGMENT REPORTING

As required by SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information," the Company reports the results of operating segments.
During the fourth quarter of Fiscal 2003, the Company changed its primary

business to be more responsive to the organization's operating structure. The
primary reportable segments are comprised of North America, Europe and All
Other. Consistent with SFAS No. 131, the Company aggregates similar operating
segments into reportable segments.

The accounting policies of the various segments are the same as those described
in "Summary of Significant Accounting Principles" in Note 1 of the Company's
annual report on Form 10-K for the fiscal year ended March 31, 2003. The Company
evaluates the performance of each segment based on operating income.
Inter-segment sales and segment interest income or expense and expenditures for
segment assets are not presented to or reviewed by management, and therefore are
not presented below.

NOTE 15: COMMITMENTS AND CONTINGENCIES

As previously disclosed in the Company's annual report on Form 10-K for the
fiscal year ended March 31, 2003, two arbitration awards against the Company for
$1.5 million and $1.3 million were being appealed. The Company has received
adverse decisions on these appeals and has taken further appeals. Based on the
facts currently available to the Company, management believes all such matters
are adequately provided for, covered by insurance, without merit, not probable
that an unfavorable outcome will result, or of such amounts which upon
resolution will not have a material adverse effect on the consolidated financial
position, results of operations or cash flow of the Company.

As previously disclosed in the Company's annual report on Form 10-K for the
fiscal year ended March 31, 2003, the Company has been named as a defendant in
two substantially similar complaints alleging violations of Sections 10(b) and
20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated
thereunder. These actions were consolidated in a lawsuit in the United States
District Court for the Western District of Pennsylvania in a case captioned In
Re Black Box Corporation Securities Litigation (Civil Action No. 03-CV-412). On
October 3, 2003, the plaintiffs in this action filed a Consolidated Class Action
Complaint in this matter. The Company believes that the claims are without merit
and intends to defend itself vigorously.

As previously disclosed on Form 8-K filed on October 28, 2003, the Company
received a formal order of investigation issued by the SEC in connection with an
inquiry pursuant to which the Staff of the SEC has requested additional
information from the Company and several of its officers, directors and team
members. The Company is responding to the SEC subpoenas and intends to cooperate
fully with the inquiry. Prior to this formal inquiry, the Company voluntarily
furnished information to the SEC. The Company believes that this inquiry
resulted from its March 11, 2003 press release concerning its anticipated fourth
quarter 2003 results and trading in Black Box securities occurring prior
thereto.

III. LIQUIDITY AND CAPITAL RESOURCES:

Cash Provided by Operating Activities for 2Q04YTD and 2Q03YTD was $30,703 and
$42,205, respectively. Reflected as a source of cash from operating activities
in 2Q04YTD are decreases in accounts receivables and unbilled accounts and other
current assets offset in part by an increase in inventories and a decrease in
accounts payable and accrued liabilities. In 2Q03YTD, decreases in accounts
receivables were a source of cash flow from operating activities, while an
increase in inventories and decreases in other current assets, accounts payable
and accrued liabilities were a use of cash flow.

In addition to Cash Provided by Operating Activities of $30,703 in 2Q04YTD, the
Company had additional cash flow of $5,186. This was generated from $2,785 of
stock option exercises, $1,600 of foreign currency exchange impact on cash, and
$801 from disposals of capital assets. The Company's 2Q04YTD cash flow was used
for repurchases of Company stock of $31,059, debt reduction of $1,988, dividend
payments of $1,824 and merger activity of $1,018.

In addition, the Company used $5,621 of cash on hand for additional stock
repurchases during the first half of the fiscal year.

Beginning in the third quarter of Fiscal 2003 and in all subsequent quarters,
the Company's Board of Directors has declared quarterly cash dividends of $0.05
per share on all outstanding shares of Black Box's common stock.

The dividend declared in 2Q04 totaled $920 and was paid on October 15, 2003 to
stockholders of record at the close of business on September 30, 2003.

As of the end of 2Q04, the Company had cash and cash equivalents of $8,422,
working capital of $115,054 and long-term debt of $47,848.

On April 4, 2000, Black Box Corporation of PA, a domestic subsidiary of the
Company, entered into a $120,000 Revolving Credit Agreement ("Long Term
Revolver") and a $60,000 Short Term Credit Agreement ("Short Term Revolver")
(together the "Syndicated Debt") with Mellon Bank, N.A. and a group of lenders.
The Long Term Revolver was scheduled to expire on April 4, 2003 and the Short
Term Revolver was scheduled to expire on April 3, 2002. In April 2002, the Long
Term Revolver was extended until April 4, 2005 and the Short Term Revolver was
extended until April 2, 2003 when it expired.

The Company's total debt at the end of 2Q04 of $48,452 was comprised of $47,700
under the Long Term Revolver and $752 of various other third party, non-employee
loans. The weighted average interest rate on all indebtedness of the Company at
the end of 2Q04 and 2Q03 was approximately 1.85% and 2.61%, respectively. In
addition, at the end of 2Q04, the Company had $4,846 of letters of credit
outstanding and $67,454 available under the Long Term Revolver.

                                       23

Interest on the Long Term Revolver is variable based on the Company's option of
selecting the bank's Euro-dollar rate plus an applicable margin or the prime
rate plus an applicable margin. The majority of the Company's borrowings are
under the Euro-rate option. The applicable margin is adjusted each quarter based
on the consolidated leverage ratio as defined in the agreement. The applicable
margin varies from 0.75% to 1.75% (0.75% at the end of 2Q04) on the Euro-dollar
rate option and from zero to 0.75% (zero at the end of 2Q04) on the prime rate
option. The Long Term Revolver provides for the payment of quarterly commitment
fees on unborrowed funds, also based on the consolidated leverage ratio. The
commitment fee percentage ranges from 0.25% to 0.375% (0.25% at the end of
2Q04). The Long Term Revolver is unsecured; however, the Company, as the
ultimate parent, guarantees all borrowings and the debt contains various
restrictive covenants.

The net cash impact of merger transactions and prior merger-related payments
during 2Q04YTD was $1,018. During 2Q04YTD, capital expenditures were $894, while
capital disposals were $1,695. Capital expenditures for Fiscal 2004 are
projected to be $3,000 to $4,000 and will be spent primarily on information
systems, general equipment and facility improvements.

The Company previously announced intentions to repurchase up to 5.5 million
shares of its Common Stock from April 1, 1999 through September 30, 2003. During
2Q04, the Company repurchased approximately 0.4 million shares for an aggregate
purchase price of $17,402 and for 2Q04YTD, repurchases totaled 0.8 million
shares for $31,961. Since inception of the repurchase program in April 1999
through 2Q04, the Company has repurchased in aggregate approximately 4.3 million
shares for approximately $196,000. Funding for the stock repurchases came from
existing cash flow. Additional repurchases of stock may occur from time to time
depending upon factors such as the Company's cash flows and general market
conditions. While the Company expects to continue to repurchase shares for the
foreseeable future, there can be no assurance as to the timing or amount of such
repurchases.

The Company has operations, clients and suppliers worldwide, thereby exposing
the Company's financial results to foreign currency fluctuations. In an effort
to reduce this risk, the Company generally sells and purchases inventory based
on prices denominated in U.S. dollars. Intercompany sales to subsidiaries are
generally denominated in the subsidiaries' local currency, although intercompany
sales to the Company's subsidiaries in Brazil, Chile, Denmark, Mexico, Norway
and Sweden are denominated in U.S. dollars.

The Company has entered and will continue in the future, on a selective basis,
to enter into forward exchange contracts to reduce the foreign currency exposure
related to certain intercompany transactions. On a monthly basis, the open
contracts are revalued to fair market value, and the resulting gains and losses
are recorded in accumulated other comprehensive income. These gains and losses
offset the revaluation of the related foreign currency denominated receivables
and payables, which are also included in accumulated other comprehensive income
in stockholders' equity on the Consolidated Balance Sheet. At September 30,
2003, the open foreign exchange contracts were in Euro, Pound sterling, Canadian
dollars, Swiss francs, Japanese yen, Swedish krona and Australian dollars. The
total open contracts, with a notional amount of approximately $13,427, have a
fair value of $13,728 and

                                       24

will expire within six months. The open contracts have contract rates of 0.8705
to 0.9023 Euro, 0.6138 to 0.634 Pound sterling, 1.3558 to 1.4121 Canadian
dollars, 1.3237 to 1.3488 Swiss francs, 111.99 to 118.36 Japanese yen, 8.0248 to
8.4025 Swedish krona and 1.4736 to 1.5571 Australian dollars, all per U.S.
dollar.

The Company believes that its cash provided by operating activities will be
sufficient to satisfy its liquidity needs for the foreseeable future.

IV. CRITICAL ACCOUNTING POLICIES:

INTRODUCTION

In preparing the Company's financial statements in conformity with accounting
principles generally accepted in the United States, judgments and estimates are
made about the amounts reflected in the financial statements. As part of the
financial reporting process, the Company's management collaborates to determine
the necessary information on which to base judgments and develop estimates used
to prepare the financial statements. Historical experience and available
information is used to make these judgments and estimates. However, different
amounts could be reported using different assumptions and in light of different
facts and circumstances. Therefore, actual amounts could differ from the
estimates reflected in the financial statements.

The Company's critical accounting policies are described in the Form 10-K for
the year ended March 31, 2003. There have been no significant changes to these
policies during the two subsequent quarters.

V. NEW ACCOUNTING PRONOUNCEMENTS:

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" ("FIN 46"). A variable interest entity ("VIE") is
one where the contractual or ownership interests in an entity change with
changes in the entity's net asset value. This interpretation requires the
consolidation of a VIE by the primary beneficiary, and also requires disclosure
about VIEs where an enterprise has a significant variable interest but is not
the primary beneficiary. The Company does not believe that this statement will
have a material impact on the Company's consolidated financial statements or
results of operations.

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities." SFAS No. 149 amends and
clarifies financial accounting and reporting for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as derivatives) and for hedging activities under SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS
No. 149 is effective for contracts entered into or modified after June 30, 2003,
except in certain instances, and for hedging relationships designated after June
30, 2003. In addition, except in certain instances, all provisions of this
Statement should be applied prospectively. The application of SFAS No. 149 did
not have a material effect on the Company's consolidated financial statements or
results of operations.

                                       25


In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity." The provisions
of SFAS No. 150 require issuers to classify as liabilities, or assets in some
circumstances, certain classes of freestanding financial instruments that embody
obligations for the issuer. The provisions of SFAS No. 150 are effective for
financial instruments entered into or modified after May 31, 2003, and otherwise
shall be effective at the beginning of the first interim period beginning after
December 15, 2003. The adoption of SFAS No. 150 is not expected to have a
material effect on the Company's consolidated financial statements or results of
operations.

VI. INFLATION:

The overall effects of inflation on the Company have been nominal. Although
long-term inflation rates are difficult to predict, the Company continues to
strive to minimize the effect of inflation through improved productivity and
cost reduction programs as well as price adjustments within the constraints of
market competition.

VII. FORWARD LOOKING STATEMENTS:

When included in this Quarterly Report on Form 10-Q or in documents incorporated
herein by reference, the words "expects," "intends," "anticipates," "believes,"
"estimates," and analogous expressions are intended to identify forward-looking
statements. Such statements are inherently subject to a variety of risks and
uncertainties that could cause actual results to differ materially from those
projected. Such risks and uncertainties include, among others, the ability of
the Company to identify, acquire and operate additional on-site technical
service companies, general economic and business conditions, competition,
changes in foreign, political and economic conditions, fluctuating foreign
currencies compared to the U.S. dollar, rapid changes in technologies, customer
preferences and various other matters, many of which are beyond the Company's
control. These and other risk factors are discussed in greater detail in the
Company's most recent Annual Report on Form 10-K on file with the Securities and
Exchange Commission. These forward-looking statements are made pursuant to the
safe harbor provisions of the Private Securities Litigation Reform Act of 1995
and speak only as of the date of this Quarterly Report on Form 10-Q. The Company
expressly disclaims any obligation or undertaking to release publicly any
updates or any changes in the Company's expectations with regard thereto or any
change in events, conditions, or circumstances on which any statement is based.
Investors should also be aware that the Company does not provide forecasts
regarding its future financial results. In addition, while the Company does,
from time to time, communicate with securities analysts and stockholders, it is
against the Company's practice to disclose to them any material non-public
information or other confidential commercial information. Accordingly,
stockholders should not assume that the Company agrees with any statement or
report issued by any analyst irrespective of the content of the statement or
report. Furthermore, the Company has a practice against issuing or confirming
financial forecasts or projections issued by others. Thus, to the extent that
reports issued by securities analysts contain any projections, forecasts or
opinions, such reports are not the responsibility of the Company.

                                       26


ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risks in the ordinary course of business that
include foreign currency exchange rates. In an effort to mitigate the risk, the
Company will enter into forward exchange contracts on a selective basis. At
September 30, 2003, the Company had open contracts, which equal approximately
$13,427 at the contract rates, with a fair value of approximately $13,728.

In the ordinary course of business, the Company is also exposed to risks that
interest rate increases may adversely affect funding costs associated with the
variable rate debt. For the three-month periods ended September 30, 2003 and
2002, an instantaneous 100 basis point increase in the interest rate would
reduce the Company's expected net income in the subsequent three months by $76
and $99, respectively, assuming the Company employed no intervention strategies.

ITEM 4 - CONTROLS AND PROCEDURES

An evaluation was performed as of September 28, 2003, under the supervision and
with the participation of Company management, including the Chief Executive
Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of the
design and operation of our disclosure controls and procedures (as defined in
Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the
"Act"). Based on that evaluation, management, including the CEO and CFO,
concluded that our disclosure controls and procedures were effective to ensure
that information required to be disclosed in reports that we file or submit
under the Act is recorded, processed, summarized and reported in accordance with
the rules and forms of the Securities and Exchange Commission. It should be
noted that the design of any system of controls is based in part upon certain
assumptions about the likelihood of future events, and there can be no absolute
assurance that any design will succeed in achieving its stated goals under all
potential future conditions, regardless of how remote. However, the controls
have been designed to provide reasonable assurance of achieving the controls'
stated goals. There have been no changes in our internal control over financial
reporting during the last fiscal quarter that have materially affected or are
reasonably likely to materially affect our internal control over financial
reporting or in other factors that could significantly affect internal controls
subsequent to their evaluation.

                            PART II OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS

As previously disclosed in the Company's annual report on Form 10-K for the
fiscal year ended March 31, 2003, two arbitration awards against the Company for
$1.5 million and $1.3 million were being appealed. The Company has received
adverse decisions on these appeals and has taken further appeals. Based on the
facts currently available to the Company, management believes all such matters
are adequately provided for, covered by insurance, without merit, not probable
that an unfavorable outcome will result, or of such amounts which upon
resolution will not have a material adverse effect on the consolidated financial
position, results of operations or cash flow of the Company.

As previously disclosed in the Company's annual report on Form 10-K for the
fiscal year ended March 31, 2003, the Company has been named as a defendant in
two substantially similar complaints alleging violations of Sections 10(b) and
20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated
thereunder. These actions were consolidated in a lawsuit in the United States
District Court for the Western District of Pennsylvania in a case captioned In
Re Black Box Corporation Securities Litigation (Civil Action No. 03-CV-412). On
October 3, 2003, the plaintiffs in this action filed a Consolidated Class Action
Complaint in this matter. The Company believes that the claims are without merit
and intends to defend itself vigorously.

As previously disclosed on Form 8-K filed on October 28, 2003, the Company
received a formal order of investigation issued by the SEC in connection with an
inquiry pursuant to which the Staff of the SEC has requested additional
information from the Company and several of its officers, directors and team
members. The Company is responding to the SEC subpoenas and intends to cooperate
fully with the inquiry. Prior to this formal inquiry, the Company voluntarily
furnished information to the SEC. The Company believes that this inquiry
resulted from its March 11, 2003 press release concerning its anticipated fourth
quarter 2003 results and trading in Black Box securities occurring prior
thereto.
