NOTE 4:  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,
which are also included in accumulated other comprehensive income.

NOTE 6:  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:

NOTE 7:  NEW ACCOUNTING STANDARDS

In August 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS
No. 144 addresses financial accounting and reporting for the impairment of
long-lived assets and for long-lived assets to be disposed of and supersedes
FASB Statement No. 121. This SFAS retains the fundamental provisions of SFAS No.
121 for recognition and measurement of the impairment of long-lived assets to be
held and used and measurement of long-lived assets to be disposed of by sale.
The provisions of this standard must be applied for fiscal years beginning after
December 15, 2001. The Company adopted SFAS No. 144 in the first quarter of
Fiscal 2003. Its adoption did not have a material effect on the Company's
financial statements or results of operations.

In April 2002, SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64,
Amendment of FASB Statement No. 13, and Technical Corrections," was issued. The
SFAS updates, clarifies and simplifies existing accounting pronouncements. While
the technical corrections to existing pronouncements are not substantive in
nature, in some instances, they may change accounting practice. The provisions
of this standard related to Statement No. 13 are effective for transactions
occurring after May 15, 2002. All other provisions of this standard must be
applied for years beginning after May 15, 2002. The application of SFAS No. 145
did not have a material effect on the Company's financial statements or results
of operations.

                (Dollars in thousands, except per share amounts)


In June 2002, the Financial Accounting Standards Board issued SFAS No. 146,
"Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146
nullifies Emerging Issues Task Force Issue No. 94-3, "Liability Recognition for
Certain Employee Termination Benefits and Other Costs to Exit an Activity,"
under which a liability for an exit cost was recognized at the date of an
entity's commitment to an exit plan. SFAS No. 146 requires that a liability for
a cost associated with an exit or disposal activity be recognized at fair value
when the liability is incurred. The provisions of this standard are effective
for exit or disposal activities that are initiated after December 31, 2002. The
Company believes that the adoption of SFAS No. 146 will not have a material
impact on its financial statements or results of operations.

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 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 and will be included in the Company's Form 10-K for Fiscal
2003.

NOTE 8 - CHANGES IN BUSINESS

During the nine months ended December 31, 2002, the Company successfully
completed two business combinations that have been accounted for using the
purchase method of accounting, June 2002 - Societe d'Installation de Reseaux
Informatiques et Electriques; and July 2002 - EDC Communications Limited and EDC
Communications (Ireland) Limited. The aggregate purchase price of these two
business combinations was $4,300 and resulted in goodwill of $3,157 and other
intangibles of approximately $348 in accordance with SFAS No. 141, "Business
Combinations," which the Company adopted during the third quarter of Fiscal
2002. The other intangibles balance consisted of non-compete agreements and
backlog. In addition, during the nine months ended December 31, 2002, the
Company paid approximately $4,000 for obligations related to mergers completed
in prior periods.

                (Dollars in thousands, except per share amounts)


As of December 31, 2002, all non-compete agreements had an estimated gross value
of $1,861 and accumulated amortization of $235. As of December 31, 2002, the
backlog intangibles had a gross value of $281 and accumulated amortization of
$256. See Note 9, "Intangible Assets."

During Fiscal 2002, the Company successfully completed 18 business combinations
that have been accounted for using the purchase method of accounting: April 2001
- - Haddad Electronic Supply, Inc., FBS Communications, L.P. and Integrated
Cabling Systems, Inc.; May 2001 - Computer Cables and Accessories Ltd; June 2001
- - Vivid Communications, Inc. and DESIGNet, Inc; July 2001 - J.C. Informatica
Integral S.A. de C.V., Consultoria en Redes S.A. de C.V. and SIC Comunicaciones

2002 - TeleAce Communication PTE Ltd. In connection with the above 18 business
combinations, the Company issued an aggregate of 510,000 shares of its common
stock and used approximately $21,000 in cash to acquire all of the outstanding
shares of the above 18 companies.

The aggregate purchase price of the above 18 companies including deal costs was
approximately $50,500 and resulted in goodwill of $43,900 and other intangibles
of approximately $1,800 in accordance with SFAS No. 141, "Business
Combinations," which the Company adopted during the third quarter of Fiscal
2002. The other intangibles balance consisted of non-compete agreements and
backlog. As of March 31, 2002, the non-compete agreements had an estimated gross
value of $1,900 and accumulated amortization of $92. As of March 31, 2002, the
backlog intangibles had a gross value of $203 and accumulated amortization of
$78.

As of December 31, 2002, certain merger agreements provide for contingent
payments of up to $5,192. Upon meeting future operating performance goals,
goodwill will be adjusted for the amount of the contingent payments.

The Company has consolidated the results of operations for each of the acquired
companies as of the respective merger date. The following table reports pro
forma information as if the acquired entities had been purchased at the
beginning of the stated periods:

NOTE 9:  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 evaluated its
intangible assets for impairment and none 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.

As of December 31, 2002, the Company's trademarks had a gross carrying amount of
$35,992 and accumulated amortization of $8,253 and the Company believes this
intangible has an indefinite life.

The Company had the following other intangibles as of December 31, 2002:



                                                     GROSS CARRYING               ACCUMULATED

NOTE 10:  TREASURY STOCK

The Company previously announced its intention to repurchase up to 2,500,000
shares of its Common Stock from April 1, 1999 through March 31, 2002. As of
March 31, 2002, the Company had repurchased 2,105,000 shares at prevailing
market prices for an aggregate purchase price of $100,355. In May 2002, the
Company's Board of Directors authorized the repurchase of an additional
1,000,000 shares. During the first nine months of Fiscal 2003, the Company
repurchased 962,500 shares for an aggregate purchase price of $37,853. Funding
for these repurchases came from existing cash flow and borrowings under existing
credit facilities.

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 4, 2002. In April 2002, the Long
Term Revolver was extended to April 4, 2005 and the Short Term Revolver was
extended to April 2, 2003. The interest on the borrowings is variable based on
the Company's option of selecting the banks prime rate plus an applicable margin
as defined in the agreement or the Euro-dollar rate plus an applicable margin as
defined in the agreement.

costs of a previously closed facility recognized at the time of one of its
acquisitions. The components of the restructuring accrual at December 31, 2002

NOTE 13:  SEGMENT REPORTING

The Company manages the business primarily on a product and service line basis.
Its two primary reportable segments are comprised of On-Site Services and Phone
Services. The "Other" information presented herein includes expenses directly
related to the Company's on-going mergers and acquisitions program. The Company
reports its two segments separately because of differences in the ways the
product and service lines are operated. Consistent with SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information," the
Company aggregates similar operating segments into reportable segments.

The Company evaluates the performance of each segment based on "Worldwide
Operating Income." A segment's worldwide operating income is its operating
income before amortization. For intercompany transactions, the segment providing
the third-party billing reports the revenues and the related profits.
Intersegment sales, segment interest income or expense and expenditures for
segment assets are not presented to or reviewed by management, and therefore are
not presented below.

    THIRD QUARTER FISCAL 2003 (3Q03) COMPARED TO THIRD QUARTER FISCAL 2002
    (3Q02):

    TOTAL REVENUES

    Total revenues for 3Q03 were $153,062, a decrease of 15% compared to 3Q02
    total revenues of $179,241. If exchange rates had remained constant from the
    third quarter last year, 3Q03 total revenues would have been $4,068 less.

    ON-SITE SERVICES REVENUES

    Revenues from on-site services were $90,165 for 3Q03 compared to $105,057
    for 3Q02. Included in 3Q03 is approximately $2,722 of revenues from mergers
    completed after 3Q02. Overall, the on-site services revenue decline was due
    to weak general economic conditions that affected customer demand offset in
    part by the impact of the Company's geographic expansion by merger of its
    on-site technical services capabilities that occurred after 3Q02.

    North America on-site services revenues were $71,008 for 3Q03 compared to
    $89,365 for 3Q02. The decrease in North America on-site services revenues
    was due to the economic conditions described above.



                                       17


    International on-site services revenues increased 22% to $19,157 for 3Q03
    from $15,692 for 3Q02. The growth of International on-site services revenues
    was driven by the Company's continued geographic expansion of its technical
    services capabilities and deeper penetration in existing markets that
    occurred after 3Q02.

    PHONE SERVICES REVENUES

    Revenues from the Company's phone services business for 3Q03 were $62,897
    compared to $74,184 for 3Q02. Phone services revenues from North America
    decreased to $31,009 for 3Q03 from $35,007 for 3Q02 while International
    phone services revenues decreased to $31,888 for 3Q03 from $39,177 for 3Q02.
    The decline in North America and International phone services revenues was
    driven by a general economic downturn.

    REVENUES BY GEOGRAPHY

    Reported revenue dollar and percentage changes over prior year's third
    quarter by geographic region were as follows: North America revenues
    decreased $22,355, or 18%, to $102,017; Europe revenues increased $570, or
    1%, to $41,457; Pacific Rim revenues decreased $2,247, or 26%, to $6,325;
    and Latin American revenues decreased $2,147, or 40%, to $3,263. If the
    exchange rate relative to the U.S. dollar had remained unchanged from 3Q02,
    the European, Pacific Rim and Latin America revenues would have decreased
    8%, 28% and 39%, respectively.

    GROSS PROFIT

    Gross profit for 3Q03 decreased to $60,639, or 39.6% of revenues, from
    $70,844, or 39.5% of revenues for 3Q02. The decrease in gross profit dollars
    over prior year was due to the decline in revenues.

    SG&A EXPENSES

    Selling, general and administrative ("SG&A") expenses for 3Q03 were $37,471,
    or 24.5% of revenues, a decrease of $5,133 over SG&A expenses of $42,604, or
    23.8% of revenues for 3Q02. The dollar decrease from 3Q02 to 3Q03 related to
    the Company's cost reduction efforts worldwide.

    OPERATING TO NET INCOME

    Operating income before intangibles amortization for 3Q03 was $23,168, or
    15.1% of revenues, compared to $28,240, or 15.8% of revenues in 3Q02.

    The decrease in operating income before intangibles amortization percentage
    was due primarily to the increase in SG&A as a percentage of revenues.

    Intangibles amortization for 3Q03 was $96 compared to 3Q02 of $82.

    Operating income (after intangibles amortization) for 3Q03 was $23,072, or
    15.1% of revenues, compared to $28,158, or 15.7% of revenues in 3Q02.


                                       18



    Net interest expense for 3Q03 decreased to $671 from $1,382 for 3Q02 due to
    debt reduction of $49,597 from 3Q02 to 3Q03 and reduction in the interest
    rate during this period.

    The tax provision for 3Q03 was $7,580, an effective tax rate of 33.9%,
    compared to 3Q02 of $9,905, an effective tax rate of 37.0%. The tax rate for
    3Q03 was lower than the currently projected annual effective tax rate of
    36.0% as the Company made the adjustment during the quarter from the
    previously expected rate of 37.0%. The Company reduced its annual effective
    tax rate to 36.0% as a result of reduced state income taxes. The annual
    effective tax rates were higher than the U.S. statutory rate of 35.0%
    primarily due to state income taxes, offset by foreign income tax credits.

    Net income for 3Q03 was $14,777, or 9.7% of revenues, compared to $16,869,
    or 9.4% of revenues for 3Q02. The increase in net income as a percentage of
    revenues was due primarily to the Company's lower effective tax rate.


    FIRST NINE MONTHS FISCAL 2003 (3Q03YTD) COMPARED TO FIRST NINE MONTHS FISCAL
    2002 (3Q02YTD):

    TOTAL REVENUES

    Total revenues for 3Q03YTD were $470,205, a decrease of 19% compared to
    3Q02YTD total revenues of $583,429. If exchange rates had remained constant
    from the same periods last year, 3Q03YTD total revenues would have been
    $9,229 less.

    ON-SITE SERVICES REVENUES

    Revenues from on-site services were $279,430 for 3Q03YTD compared to
    $343,382 for 3Q02YTD. Included in 3Q03YTD is approximately $7,725 of
    revenues from mergers completed after 3Q02. Overall, the on-site services
    revenue decline was due to weak general economic conditions that affected
    customer demand offset in part by the impact of the Company's geographic
    expansion by merger of its on-site technical services capabilities that
    occurred after 3Q02.

    North America on-site services revenues were $224,877 for 3Q03YTD compared
    to $301,972 for 3Q02YTD. The decrease in North America on-site services
    revenues was due to the economic conditions described above.

    International on-site services revenues increased 32% to $54,553 for 3Q03YTD
    from $41,410 for 3Q02YTD. The growth of International on-site services
    revenues was driven by the Company's geographic expansion of its technical
    services capabilities and deeper penetration in existing markets that
    occurred after 3Q02.

    PHONE SERVICES REVENUES

    Revenues from the Company's phone services business for 3Q03YTD were
    $190,775 compared to $240,047 for 3Q02YTD. Phone services revenues from
    North America decreased to $98,611 for 3Q03YTD from $122,054 for 3Q02YTD
    while International phone services revenues decreased to $92,164 for 3Q03YTD
    from $117,993 for 3Q02YTD. The


                                       19


    decline in North America and International phone services revenues was
    driven by the general economic downturn.

    REVENUES BY GEOGRAPHY

    Reported revenue dollar and percentage changes over prior year's first nine
    months by geographic region were as follows: North America revenues
    decreased $100,538, or 24%, to $323,488; Europe revenues decreased $1,849,
    or 2%, to $115,847; Pacific Rim revenues decreased $6,160, or 24%, to
    $19,572; and Latin American revenues decreased $4,677, or 29%, to $11,298.
    If the exchange rate relative to the U.S. dollar had remained unchanged from
    prior year, the European, Pacific Rim and Latin America revenues would have
    decreased 9%, 25% and 29%, respectively.

    GROSS PROFIT

    Gross profit for 3Q03YTD decreased to $185,911, or 39.5% of revenues, from
    $224,819, or 38.5% of revenues for 3Q02YTD. The decrease in gross profit
    dollars over prior year was due primarily to the decline in revenues while
    the increase in gross profit percentage was due primarily to cost reduction
    efforts in the Company's phone services business.

    SG&A EXPENSES

    Selling, general and administrative ("SG&A") expenses for 3Q03YTD were
    $113,788, or 24.2% of revenues, a decrease of $27,385 over SG&A expenses of
    $141,173, or 24.2% of revenues for 3Q02YTD. Included in prior year's first
    nine months was a special expense of $5,027 primarily attributable to the
    Company reserving for two accounts receivable from customers who filed for
    Chapter 11 bankruptcy protection during 1Q02. The remaining dollar decrease
    from 3Q02YTD to 3Q03YTD related to the Company's cost reduction efforts
    worldwide.

    OPERATING TO NET INCOME

    Operating income before intangibles amortization for 3Q03YTD was $72,123, or
    15.3% of revenues, compared to $83,646, or 14.3% of revenues in 3Q02YTD.

    If the Company had not incurred the special expense described above,
    operating income before intangibles amortization for 3Q02YTD would have been
    $88,673, or 15.2% of revenues.

    Intangibles amortization for 3Q03YTD was $305 compared to 3Q02YTD of $107.

    Operating income (after intangibles amortization) for 3Q03YTD was $71,818,
    or 15.3% of revenues, compared to $83,539, or 14.3% of revenues in 3Q02YTD.

    Net interest expense for 3Q03YTD decreased to $2,209 from $5,367 for 3Q02YTD
    due to debt reduction of $49,597 from 3Q02 to 3Q03 and reduction in the
    interest rate during this period.

    The tax provision for 3Q03YTD was $25,018, an effective tax rate of 36.0%,
    compared to 3Q02YTD of $28,823, an effective tax rate of 37.0%. The Company
    reduced its annual effective tax rate to 36.0% as a result of reduced state
    income taxes. The annual



                                       20


    effective tax rates were higher than the U.S. statutory rate of 35.0%
    primarily due to state income taxes, offset by foreign income tax credits.

    Net income for 3Q03YTD was $44,477, or 9.5% of revenues, compared to
    $49,094, or 8.4% of revenues for 3Q02YTD. Excluding the special charge
    described above in SG&A expenses, net income for 3Q02YTD would have been
    $52,261, or 9.0% of revenues. The increase in net income as a percentage of
    revenue was primarily due to the Company's cost reduction efforts.


    LIQUIDITY AND CAPITAL RESOURCES:

    Cash flow from operating activities (defined by generally accepted
    accounting principles as net income plus non-cash charges of depreciation
    and amortization, less changes in working capital) for 3Q03 and 3Q02 was
    $24,523 and $25,948, respectively. Reflected as a source of cash flow from
    operating activities in 3Q03 are decreases in unbilled accounts and other
    current assets offset in part by increases in accounts receivables and
    inventories and decreases in accounts payable and accrued liabilities. In
    3Q02, decreases in accounts receivables, inventories and other current
    assets were a source of cash flow from operating activities, while decreases
    in accounts payable and other liabilities were a use of cash flow.

    During 3Q03, free cash flow (defined as cash flow from operating activities
    less capital expenditures and foreign currency translation adjustments, plus
    proceeds from stock option exercises) was $28,017 compared to $28,891 for
    3Q02. The Company's 3Q03 free cash flow was used to repurchase approximately
    $17,000 of Company stock, reduce debt by approximately $10,000 and increase
    cash on hand by approximately $1,000.

    Also during 3Q03, the Company's Board of Directors declared a quarterly cash
    dividend of $0.05 per share on all outstanding shares of Black Box's common
    stock, payable on January 15, 2003 to stockholders of record at the close of
    business on December 31, 2002. Accordingly, the Company recorded a liability
    of $975 in 3Q03.

    Cash flow from operating activities for 3Q03YTD and 3Q02YTD was $62,359 and
    $50,337, respectively. Reflected as a source of cash flow from operating
    activities during 3Q03YTD are decreases in accounts receivable, unbilled
    accounts, inventories and other current assets, offset in part by decreases
    in accounts payable and accrued liabilities, all generally related to the
    decline in revenues. For 3Q02YTD, decreases in accounts receivables and
    inventories were a source of cash flow from operating activities, while
    decreases in other current assets and various liabilities were a use of cash
    flow.

    For 3Q03YTD, free cash flow as defined above was $71,005 compared to $55,504
    for 3Q02YTD. The Company's 3Q03YTD free cash flow was used to repurchase
    approximately $38,000 of Company stock, reduce debt by approximately $26,000
    and pay merger obligations of approximately $7,000.

    As of the end of 3Q03, the Company had cash and cash equivalents of $13,447,
    working capital of $133,749 and long-term debt of $51,469.



                                       21


    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.

    The Company's total debt at the end of 3Q03 of $53,230 was comprised of
    $51,000 under the Long Term Revolver and $2,230 of various other loans. The
    weighted average interest rate on all indebtedness of the Company for 3Q03
    and 3Q02 was approximately 2.43% and 3.71%, respectively. The weighted
    average interest rate on all indebtedness of the Company as the end of 3Q03
    was 2.17%. In addition, at the end of 3Q03, the Company had $3,565 of
    letters of credit outstanding and $125,435 available under the Syndicated
    Debt.

    Interest on the Syndicated Debt 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 3Q03) on
    the Euro-dollar rate option and from zero to 0.75% (zero at the end of 3Q03)
    on the prime rate option. The Syndicated Debt provides for the payment of
    quarterly commitment fees on unborrowed funds, also based on the
    consolidated leverage ratio. The commitment fee percentage ranges from 0.20%
    to 0.375% (0.20% for the Short Term Revolver and 0.25% for the Long Term
    Revolver at the end of 3Q03). The Syndicated Debt 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 3Q03YTD was $272 while capital expenditures, net of disposals, were
    $26. Capital expenditures, net of disposals, for all of Fiscal 2003 are
    projected to be approximately $2,000 and will be focused primarily on
    information systems and facility improvements.

    The Company previously announced its intention to repurchase up to 2,500,000
    shares of its Common Stock from April 1, 1999 through March 31, 2002. As of
    March 31, 2002, the Company had repurchased 2,105,000 shares at prevailing
    market prices for an aggregate purchase price of $100,355. In May 2002, the
    Company's Board of Directors approved the repurchase of an additional
    1,000,000 shares of its Common Stock. During the first nine months of Fiscal
    2003, the Company repurchased 962,500 shares for an aggregate purchase price
    of $37,853. Funding for these repurchases came from existing cash flow and
    borrowings under credit facilities.

    The Company has operations, customers 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
    gains and losses resulting from the revaluation of the intercompany balances
    denominated in foreign currencies are recorded to accumulated other
    comprehensive income.


                                       22


    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, which are also included in accumulated
    other comprehensive income. At the end of 3Q03, the open foreign exchange
    contracts related to intercompany transactions were in Euro, Pound sterling,
    Canadian dollars, Swiss francs, Japanese yen and Australian dollars. These
    open contracts are valued at approximately $27,014 and will expire in one to
    six months. The open contracts have an average contract rate of 1.01 Euro,
    0.6474 Pound sterling, 1.5754 Canadian dollars, 1.494 Swiss francs, 121.35
    Japanese yen and 1.83 Australian dollars, all per U.S. dollar.

    The Company believes that its cash flow from operations and its existing
    credit facilities will be sufficient to satisfy its liquidity needs for the
    foreseeable future.


    INTANGIBLE ASSETS:

    In accordance with SFAS No. 142, "Goodwill and Other Intangible Assets,"
    adopted by the Company on April 1, 2001, the Company evaluates its
    intangible assets for impairment during the third quarter of each fiscal
    year, with any resulting impairment reflected as an operating expense. Its
    intangible assets were initially evaluated for impairment as of April 1,
    2001 and then again during the third quarters of Fiscal 2002 and Fiscal 2003
    by comparing the fair value of each reporting unit to its carrying value,
    and no impairment existed.


    CRITICAL ACCOUNTING POLICIES:

    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.

    In addition to the significant accounting policies described in Note 1 of
    Form 10-K, the Company believes that the following discussion addresses its
    critical accounting policies.


    REVENUE RECOGNITION

    The Company recognizes revenues for phone services operations when title
    transfers at the time of shipment and the price for the product has been
    determined.

    For its on-site services, the Company recognizes revenues on short-term
    projects (generally projects with a duration of less than one month) as the
    projects are completed and invoiced to


                                       23


    the client. Revenues from long-term projects (projects with a duration of
    greater than one month, generally two to four months) are recognized
    according to the percentage of completion method. Under the percentage of
    completion method, income is recognized based on a ratio of estimated costs
    incurred to total estimated contract costs. Losses, if any, on such
    contracts are provided in full when they become known. Billing in excess of
    costs and estimated earnings on uncompleted contracts are classified as
    current liabilities and any costs and estimated earnings in excess of
    billings are classified as current assets.


    ACCOUNTING FOR JUDGMENT AND ESTIMATES

    The Company establishes reserves when it is probable that a liability or
    loss has been incurred and the amount can be reasonably estimated. Reserves
    by their nature relate to uncertainties that require exercise of judgment
    both in accessing whether or not a liability or loss has been incurred and
    estimating any amount of potential loss. The most important areas of
    judgment and estimates affecting the Company's financial statements include
    accounts receivable collectibility, inventory valuation, pending litigation
    and the realization of deferred tax assets.


    LONG-LIVED ASSETS

    The Company evaluates the recoverability of property, plant and equipment
    and intangible assets other than goodwill whenever events or changes in
    circumstances indicate the carrying amount of any such assets may not be
    fully recoverable. Changes in circumstances include technological advances,
    changes in the Company's business model, capital strategy, economic
    conditions or operating performance. The Company's evaluation is based upon,
    among other things, assumptions about the estimated future undiscounted cash
    flows these assets are expected to generate. When the sum of the
    undiscounted cash flows is less than the carrying value, the Company would
    recognize an impairment loss. The Company continually applies its best
    judgment when performing these evaluations to determine the timing of the
    testing, the undiscounted cash flows used to assess recoverability and the
    fair value of the asset.

    The Company evaluates the recoverability of the goodwill attributable to
    each of its reporting units as required under SFAS No. 142, "Goodwill and
    Other Intangible Assets," by comparing the fair value of each reporting unit
    with its carrying value. The Company continually applies its best judgment
    when performing these evaluations to determine the financial projections
    used to assess the fair value of each reporting unit.


    RESTRUCTURING

    The Company accrues the cost of restructuring activities in accordance with
    the appropriate accounting guidance depending upon the facts and
    circumstances surrounding the situation. The Company exercises its judgment
    in estimating the total costs of each of these activities. As these
    activities are implemented, the actual costs may differ from the estimated
    costs due to changes in the facts and circumstances that were not foreseen
    at the time of the initial cost accrual.



                                       24




    NEW ACCOUNTING PRONOUNCEMENTS:

    In August 2001, the Financial Accounting Standards Board ("FASB") issued
    SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived
    Assets." SFAS No. 144 addresses financial accounting and reporting for the
    impairment of long-lived assets and for long-lived assets to be disposed of
    and supersedes FASB Statement No. 121. This SFAS retains the fundamental
    provisions of SFAS No. 121 for recognition and measurement of the impairment
    of long-lived assets to be held and used and measurement of long-lived
    assets to be disposed of by sale. The provisions of this standard must be
    applied for fiscal years beginning after December 15, 2001. The Company
    adopted SFAS No. 144 in the first quarter of Fiscal 2003. Its adoption did
    not have a material effect on the Company's financial statements or results
    of operations.

    In April 2002, SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and
    64, Amendment of FASB Statement No. 13, and Technical Corrections," was
    issued. The SFAS updates, clarifies and simplifies existing accounting
    pronouncements. While the technical corrections to existing pronouncements
    are not substantive in nature, in some instances, they may change accounting
    practice. The provisions of this standard related to SFAS No. 13 are
    effective for transactions occurring after May 15, 2002. All other
    provisions of this standard must be applied for years beginning after May
    15, 2002. The application of SFAS No. 145 did not have a material effect on
    the Company's financials statements or results of operations.

    In June 2002, the Financial Accounting Standards Board issued SFAS No. 146,
    "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No.
    146 nullifies Emerging Issues Task Force Issue No. 94-3, "Liability
    Recognition for Certain Employee Termination Benefits and Other Costs to
    Exit an Activity," under which a liability for an exit cost was recognized
    at the date of an entity's commitment to an exit plan. SFAS No. 146 requires
    that a liability for a cost associated with an exit or disposal activity be
    recognized at fair value when the liability is incurred. The provisions of
    this standard are effective for exit or disposal activities that are
    initiated after December 31, 2002. The Company believes that the adoption of
    SFAS No. 146 will not have a material impact on its financial statements or
    results of operations.

    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 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


                                       25


    requirements of Statement 123 are effective for fiscal years ending after
    December 15, 2002 and will be included in the Company's Form 10-K for Fiscal
    2003.


    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.


    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
    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.





                                       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
December 31, 2002, the Company had open contracts, which equal approximately
$27,014 at the contract rates, with a fair value of approximately $27,980.

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
$51,000 of variable rate debt. For the three-month periods ended December 31,
2002 and 2001, an instantaneous 100 basis point increase in the interest rate
would reduce the Company's expected net income in the subsequent three months by
$85 and $257, respectively, assuming the Company employed no intervention
strategies.


ITEM 4 - CONTROLS AND PROCEDURES

Based on their evaluation, as of a date within 90 days of the filing date of
this Form 10-Q, our Chief Executive Officer and Chief Financial Officer have
concluded that our disclosure controls and procedures (as defined in Rule
13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934, as amended)
are effective. There have been no significant changes in internal controls or in
other factors that could significantly affect these controls subsequent to the
date of their evaluation, including any corrective actions with regard to
significant deficiencies and material weaknesses.

                            PART II OTHER INFORMATION

ITEM 5 - OTHER INFORMATION

In November 2002, the Audit Committee of the Board of Directors reviewed the
proposed services of the Company's independent accountants, Ernst & Young, LLP.
The Committee pre-approved payment of up to $125,000 for assistance with tax
compliance and up to $100,000 for other non-audit services such as tax planning
initiatives and other projects when identified.
