                   WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (unaudited)
1.       ORGANIZATION

         WESCO International, Inc. and its subsidiaries (collectively, "WESCO"),
headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of
electrical supplies and equipment and is a provider of integrated supply
procurement services. WESCO is engaged principally in one line of business-the
sale of electrical products and maintenance, repair and operating supplies.
WESCO currently operates branch locations in the United States, Canada, Mexico,
Puerto Rico, Guam, Singapore and the United Kingdom.

         Subsequent to the completion in June 1998 of a leveraged
recapitalization, WESCO was substantially owned by an investor group led by
affiliates of The Cypress Group L.L.C. ("Cypress") with WESCO's management
retaining the remaining interest.

         On May 17, 1999, WESCO completed an initial public offering of
11,183,750 shares of common stock at $18.00 per share (see Note 3).


2.       ACCOUNTING POLICIES

Basis of Presentation

         The unaudited condensed consolidated financial statements include the
accounts of WESCO and all of its subsidiaries and have been prepared in
accordance with Rule 10-01 of the Securities and Exchange Commission. The
unaudited condensed consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
included in WESCO's 1998 Annual Report on Form 10-K filed with the Securities
and Exchange Commission.

         The unaudited condensed consolidated balance sheet as of September 30,
1999, the unaudited condensed consolidated statements of operations for the
three months and nine months ended September 30, 1998 and 1999, and the
unaudited condensed consolidated statements of cash flows for the nine months
ended September 30, 1998 and 1999, in the opinion of management, have been
prepared on the same basis as the audited consolidated financial statements and
include all adjustments necessary for the fair presentation of the results of
the interim periods. All adjustments reflected in the condensed consolidated
financial statements are of a normal recurring nature. Results for the interim
periods presented are not necessarily indicative of the results to be expected
for the full year. Certain prior period amounts have been reclassified in order
to conform to the current period presentation.

Recent Accounting Pronouncement

         In June 1998, the Financial Accounting Standards Board issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities." This
statement, as amended, is required to be adopted by WESCO as of January 1, 2001,
although early adoption is permitted. This statement requires the recognition of
the fair value of any derivative financial instrument on the balance sheet.
Changes in fair value of the derivative and, in certain instances, changes in
the fair value of an underlying hedged asset or liability, are recognized
through either income or as a component of other comprehensive income.
Management does not expect this statement will have a material impact on the
results of operations or financial position of WESCO.


3.       INITIAL PUBLIC OFFERING

         On May 17, 1999, WESCO completed its initial public offering of
11,183,750 shares of common stock ("Offering") at $18.00 per share. In
connection with the Offering, certain employee rights to require WESCO to
repurchase outstanding redeemable common stock were terminated and approximately
$31.5 million of convertible notes were converted into common stock. Proceeds
from the Offering (after deducting Offering costs) totaling $187.6 million and
borrowings of approximately $65 million were used to redeem all of the 11.125%
senior discount notes ($62.8 million), to repay the revolving credit and term
loan facilities ($188.8 million).




                                       5

         In connection with the Offering, on April 11, 1999, the Board of
Directors approved a 57.8 to one stock split effected in the form of a stock
dividend of WESCO's common stock. The Board of Directors also reclassified the
Class A common stock into common stock, increased the authorized common stock to
210,000,000 shares and the authorized Class B common stock to 20,000,000 shares
and authorized 20,000,000 shares of $.01 par preferred stock, all effective May
11, 1999. In this report, all share and per share data have been restated to
reflect the stock split.


4.       EXTRAORDINARY ITEM

         In the second quarter of 1999, WESCO (i) entered into a new $400
million revolving credit facility and terminated its existing term loans and
revolving facility; (ii) terminated its existing accounts receivable
securitization program and entered into a new accounts receivable securitization
program; and (iii) retired all of its outstanding 11.125% senior discount notes.
In conjunction with these transactions, approximately $8.9 million of deferred
financing charges were written off and redemption costs of $8.3 million were
incurred to redeem the 11.125% senior discount notes. These transactions
resulted in an extraordinary loss of $10.5 million, net of income tax benefits
of $6.7 million.


5.       RECAPITALIZATION

         On June 5, 1998, WESCO repurchased and retired 61,862,068 shares of
common stock held by certain shareholders for net consideration of approximately
$653.5 million ("Equity Consideration"). In addition, WESCO repaid approximately
$379.1 million of then outstanding indebtedness, and sold 29,604,351 shares of
common stock to an investor group led by affiliates of Cypress representing
approximately 88.7% of WESCO for an aggregate cash consideration of $318.1
million ("Cash Equity Contribution") (collectively, "Recapitalization").
Existing management retained approximately an 11.3% interest in WESCO after the
Recapitalization. WESCO funded the Equity Consideration and the repayment of
indebtedness from proceeds of the Cash Equity Contribution, issuance of
approximately $351 million of senior subordinated and senior discount notes, a
$170 million credit facility and the sale of approximately $250 million of
accounts receivable. Given the 11.3% retained ownership, the transaction was
treated as a recapitalization for financial reporting purposes and, accordingly,
the historical bases of WESCO's assets and liabilities were not affected.

         In connection with the Recapitalization, WESCO recorded a one-time
charge of $51.8 million related to investment banking fees of $13.8 million,
compensation charges of $11.3 million associated with one-time bonuses paid to
certain members of management, transaction fees of $9.5 million paid to Cypress,
compensation charges of $6.2 million associated with the cash settlement of
certain stock options, compensation charges of $4.1 million associated with the
acceleration of vesting of one former executive's stock options issued at a
discount and other non-capitalized transaction fees and expenses amounting to
$6.9 million.


6.       ACCOUNTS RECEIVABLE SECURITIZATION

         In June 1999, WESCO and certain of its subsidiaries terminated its
previous accounts receivable securitization program and entered into a new $350
million accounts receivable securitization program ("Receivables Facility") with
another financial institution, as modified in September 1999. Under the
Receivables Facility, WESCO sells, on a continuous basis, to WESCO Receivables
Corporation, a wholly-owned, special purpose subsidiary ("SPC") an undivided
interest in all eligible accounts receivable. The SPC sells to a third-party
conduit all the receivables while maintaining a subordinated interest, in the
form of overcollateralization, in a portion of the receivables. WESCO has agreed
to continue servicing the sold receivables for the financial institution at
market rates; accordingly, no servicing asset or liability has been recorded.



                                       6
<PAGE>   8


         As of December 31, 1998 and September 30, 1999, securitized accounts
receivable totaled $360.1 million and $412.7 million, respectively, of which the
subordinated retained interest was $84.1 million and $75.5 million,
respectively. Accordingly, $276.0 million and $337.2 million of accounts
receivable balances were removed from the consolidated balance sheets at
December 31, 1998 and September 30, 1999. Net proceeds from the transactions
totaled $274.2 million in the first nine months of 1998 and $60.0 million in the
first nine months of 1999. Costs associated with the Receivables Facility
totaled $6.2 million in the first nine months of 1998, and $14.2 million in the
first nine months of 1999. These amounts are recorded as other expenses in the
condensed consolidated statement of operations and are primarily related to the
discount and loss on the sale of accounts receivables, partially offset by
related servicing revenue.


7.       LONG-TERM DEBT

         The following table sets forth WESCO's outstanding indebtedness.

(2)      Net of original issue discount and purchase discount of $33,266 and

         During the second quarter of 1999, WESCO completed the Offering and, as
discussed below, refinanced the majority of its long-term debt facilities. As a
result of these transactions, the term loans and the senior discount notes were
repaid, the prior revolving facility was refinanced and certain convertible
notes were converted into WESCO common stock.

         The term loans and prior revolving facility borrowings were made
pursuant to a credit agreement entered into by and between WESCO and certain
financial institutions. This credit agreement provided for term loan facilities
in an aggregate principal amount of $270 million and a $100 million revolving
credit facility. This facility provided variable-rate borrowings tied to market
indices plus applicable borrowing margins.

         The senior discount notes with an aggregate principal amount of $87
million and a stated rate of 11.125% were issued with an original issue discount
("OID") of $36.5 million that was being accreted over the period ending June 1,
2003.


Revolving Credit Facility

         On June 29, 1999, WESCO Distribution, Inc. entered into a new $400
million revolving credit facility with a consortium of financial institutions.
The revolving credit facility, which matures in June 2004, consists of up to
$365 million of revolving loans denominated in US dollars and a Canadian
sublimit totaling $35 million. Borrowings under the revolving credit facility
are collateralized by substantially all the assets, excluding real property, of
WESCO Distribution, Inc. and are guaranteed by WESCO International, Inc. and
certain subsidiaries.




                                       7
<PAGE>   9

         Borrowings bear rates of interest equal to various indices, at WESCO's
option plus a borrowing margin. At September 30, 1999, the interest rate on
revolving credit facility borrowings was 6.81%. A commitment fee of 30 to 50
basis points per annum is due on unused portions of the revolving credit
facility.

         Capitalized debt issuance costs related to the new revolving credit
facility were approximately $1.8 million and are being amortized to interest
expense on a straight-line basis, which does not differ materially from the
effective-interest method, over the life of the credit agreement.

         The revolving credit facility contains various restrictive covenants
that, among other things, include limitations on (i) dividend payments or
certain other restricted payments or investments; (ii) the incurrence of
additional indebtedness and guarantees or issuance of additional stock; (iii)
creation of liens; (iv) mergers, consolidation or sales of substantially all of
WESCO's assets; (v) certain transactions among affiliates; (vi) payments by
certain subsidiaries to WESCO; and (vii) capital expenditures. In addition, the
agreements require WESCO to meet certain leverage, working capital and interest
coverage ratios.


8.       LONG-TERM INCENTIVE PLAN

         On April 26, 1999, the Board of Directors approved the Long-Term
Incentive Plan ("LTIP"). The LTIP provides for stock participation in the form
of options, restricted stock awards and performance awards by certain key
employees of WESCO. The LTIP covers a maximum of 6,936,000 shares of WESCO's
common stock. The exercise price is determined by the Compensation Committee of
the Board of Directors.


9.       ACQUISITIONS

         On September 11, 1998, WESCO acquired substantially all the assets and
assumed substantially all liabilities and obligations relating to the operations
of Bruckner Supply Company, Inc. ("Bruckner"), a privately owned company
headquartered in Port Washington, New York. Bruckner is a provider of integrated
supply procurement and outsourcing activities for large industrial companies.
Net sales totaled approximately $222 million in 1997.

         The following unaudited pro forma information assumes that the Bruckner
acquisition had occurred as of January 1, 1998. Adjustments to arrive at the pro
forma information include, among others, those related to acquisition financing,
amortization of goodwill and the related tax effects of such adjustments at an
assumed rate of 39%.

         The pro forma financial information does not purport to present what
WESCO's results of operations would have been if the Bruckner acquisition had
actually occurred as of January 1, 1998, or to project WESCO's results of
operations for any future period.

         During 1999, WESCO purchased four electrical supply distributors with
annual sales of approximately $70 million for an aggregate consideration of
$24.4 million, resulting in goodwill of approximately $9.5 million.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with the
information in the unaudited condensed consolidated financial statements and
notes thereto included herein and WESCO International Inc.'s Financial
Statements and Management's Discussion and Analysis of Financial Condition and
Results of Operations included in its 1998 Annual Report on Form 10-K.

GENERAL

         WESCO is a leading distributor of electrical products and other
industrial MRO supplies and related services in North America. WESCO has over
340 branches and five distribution centers strategically located in 48 states,
nine Canadian provinces, Puerto Rico, Guam, Mexico, the United Kingdom and
Singapore. WESCO serves over 130,000 customers worldwide, offering over
1,000,000 products from over 23,000 suppliers. WESCO's diverse customer base
includes a wide variety of industrial companies; contractors for industrial,
commercial and residential projects; utility companies; and commercial,
institutional and governmental customers. Approximately 90% of WESCO's net sales
are generated from operations in the U.S., 9% from Canada and the remainder from
other countries.


RECENT DEVELOPMENTS

         Recent developments affecting the results of operations and financial
position of WESCO include the following:

         Initial Public Offering. On May 17, 1999, WESCO completed its initial
public offering of 11,183,750 shares of common stock ("Offering") at $18.00 per
share. In connection with the Offering, certain employee rights to require WESCO
to repurchase outstanding redeemable common stock were terminated and
approximately $31.5 million of convertible notes were converted into common
stock. Proceeds from the Offering (after deducting Offering costs) totaling
$187.6 million and borrowings of approximately $65 million were used to redeem
all of the senior discount notes ($62.8 million), to repay the revolving credit
and term loan facilities ($188.8 million).

         Credit Refinancing. On June 29, 1999, WESCO Distribution, Inc. entered
into a new $400 million revolving credit facility with a consortium of financial
institutions. WESCO believes the new credit agreement provides greater financial
flexibility and lower annual costs of financing than the previous credit
agreement. In addition, WESCO entered into a new $350 million accounts
receivable securitization program that provides for a larger amount of eligible
accounts receivable and lower costs than the previous securitization program.

         In conjunction with these transactions, approximately $8.9 million of
deferred financing charges were written off and redemption costs of $8.3 million
were incurred to redeem the 11.125% senior discount notes. These transactions
resulted in an extraordinary loss of $10.5 million, net of income tax benefits
of $6.7 million.

         Acquisitions. During the first nine months of 1999, WESCO purchased
four electrical supply distributors with annual sales of approximately $70
million for an aggregate consideration of $24.4 million, resulting in goodwill
of approximately $9.5 million.

               ----------------------------------------------------------------------------------
</TABLE>

         Net Sales. Sales in the third quarter of 1999 increased by $125.5
million, or 16.1%, to $903.2 million compared with $777.7 million in the
prior-year quarter, primarily due to sales attributable to acquired companies.
Core business sales increased approximately 7% in the quarter-to-quarter
comparison. The mix of direct shipment sales increased to approximately 46% in
the third quarter of 1999 from 41% in the third quarter of 1998 as a result of
the Bruckner acquisition completed in September 1998. Substantially all of
Bruckner's sales are direct shipment.

         Gross Profit. Gross profit for the third quarter of 1999 increased by
$18.5 million to $156.4 million from $137.9 million for the third quarter of
1998. Gross profit margin declined to 17.3% in the current-year quarter from
17.7% in the third quarter of 1998. Gross profit margin in 1999 includes the
effect of an increase in direct shipment sales associated with the Bruckner
acquisition. Direct ship gross margins are lower than those of other sales;
however, operating profit margins are often higher, since the product handling
and fulfillment costs associated with direct shipments are much lower. Excluding
the effects of the Bruckner acquisition, gross profit margin was 17.8% for the
third quarter of 1998 and 1999.

         Selling, General and Administrative Expenses. For the third quarter of
1999, selling, general and administrative ("SG&A") expenses increased $7.3
million, or 6.9%, to $113.0 million when compared to the third quarter of 1998.
This increase was comprised of a $10.9 million increase in salaries, wages and
commissions and a $6.2 million increase in certain other operating expenses such
as travel, transportation, telephone and sales promotion. These increases were
offset by a $5.5 million reduction in certain incentive-based compensation
expenses and a $4.3 million reduction in certain discretionary benefits.
Companies acquired since the beginning of the third quarter of 1998 added $8.3
million of the total increase in operating expenses. As a percent of sales, SG&A
expenses declined to 12.5% compared with 13.6% in the prior year quarter.

         Depreciation and Amortization. Depreciation and amortization increased
$1.2 million to $5.1 million reflecting higher amortization of goodwill from
acquisitions and increases in property, buildings and equipment over the prior
year.

         Income from Operations. Income from operations increased $9.9 million,
or 35.1%, to $38.2 million in the third quarter of 1999, compared with $28.3
million in the prior-year quarter. The increase was primarily due to higher
gross profit, partially offset by the increases in SG&A as explained above.

<PAGE>   15


         Interest and Other Expense. Interest expense totaled $10.7 million for
the third quarter of 1999, a decrease of $2.4 million from the same period in
1998. The decline primarily was due to lower outstanding debt related to the
Offering as well as benefits resulting from the credit agreement refinancing.
Other expense totaled $4.7 million and $3.7 million in the third quarter of 1999
and 1998, respectively, reflecting costs associated with the accounts receivable
securitization.

         Income Taxes. Income tax expense totaled $9.1 million in the third
quarter of 1999 and the effective tax rate was 39.8%. In the third quarter of
1998, income tax benefits totaled $14.9 million and the effective tax rate was
129.6%. The effective tax rate in the third quarter of 1998 was attributable to
the proportion of certain nondeductible recapitalization costs and other
nondeductible permanent differences relative to expected levels of operating
income. The effective tax rates differ from the federal statutory rate primarily
due to state income taxes and nondeductible expenses.

         Net Income. Net income and diluted earnings per share totaled $13.8
million and $0.27, respectively, for the third quarter of 1999, compared with
$26.4 million, or $0.65 per diluted share, for the third quarter of 1998. The
comparative results were affected by $14.9 million of income tax benefits
recorded in 1998.

         Net Sales. Sales in the first nine months of 1999 increased by $325.3
million, or 14.7%, to $2.5 billion compared with $2.2 billion in the prior-year
period primarily due to sales attributable to acquired companies. Core business
sales increased approximately 3% over the prior-year period. The mix of direct
shipment sales increased to approximately 46% in the first nine months of 1999
from 40% in the first nine months of 1998 as a result of the Bruckner
acquisition completed in September 1998. Substantially all of Bruckner's sales
are direct shipment.

         Gross Profit. Gross profit for the first nine months of 1999 increased
by $54.3 million to $452.2 million from $397.8 million for the first nine months
of 1998. Gross profit margin was 17.8% and 17.9% in the first nine months of
1999 and 1998, respectively. Excluding the effects of the Bruckner acquisition,
which has a higher proportion of lower-margin direct ship sales, gross profit
margin increased to 18.4% from 18.0% in the prior-year period due to gross
margin improvement initiatives.

<PAGE>   16
         Selling, General and Administrative Expenses. SG&A expenses increased
$27.9 million, or 9.0%, to $338.7 million. This increase was substantially due
to incremental expenses of companies acquired during 1998 and 1999 and, to a
lesser extent, increased SG&A in WESCO's core business. These increases
were partially offset by reductions in certain incentive-based compensation
expenses and a reduction in certain discretionary benefits. As a percent of
sales, SG&A expenses declined to 13.3% compared with 14.0% in the year-earlier
period reflecting a lower relative cost structure associated with the Bruckner
acquisition.

         Depreciation and Amortization. Depreciation and amortization increased
$4.6 million to $14.8 million reflecting higher amortization of goodwill from
acquisitions and increases in property, buildings and equipment over the
prior-year period.

         Income from Operations. Income from operations increased $73.6 million
to $98.7 million in the first nine months of 1999, compared with $25.1 million
in the prior-year period. Excluding the nonrecurring recapitalization costs in
1998, operating income increased $21.8 million. The increase was primarily due
to higher gross profit offset by increased operating costs as explained above.

         Interest and Other Expense. Interest expense totaled $37.5 million for
the first nine months of 1999, an increase of $7.9 million over the same period
in 1998. The increase was primarily due to the higher levels of borrowings
associated with the recapitalization and acquisitions.

         Other expense totaled $14.2 million and $6.2 million in the first nine
months of 1999 and 1998, respectively, reflecting costs associated with the
accounts receivable securitization program which commenced in June 1998.

         Income Taxes. Income tax expense totaled $18.7 million in the first
nine months of 1999 and the effective tax rate was 39.9%. In the first nine
months of 1998, income tax benefits totaled $27.6 million and were primarily due
to the one-time $51.8 million recapitalization costs recorded in the second
quarter of 1998. The effective tax rate in the first nine months of 1998 was
256.1%. The effective tax rate for each interim period reflects management's
estimate of the expected rate for the full year. The higher effective rate in
1998 was attributable to the proportion of certain nondeductible
recapitalization costs and other nondeductible permanent differences relative to
expected levels of operating income.

         Income Before Extraordinary Item and Net Income. For the first nine
months of 1999, income before extraordinary item totaled $28.2 million, or $0.62
per diluted share, compared with $16.8 million, or $0.35 per diluted share, in
the first nine months of 1998. The increases in the comparison are primarily due
to revenue growth and nonrecurring recapitalization costs included in the 1998
results.

         Net income and diluted earnings per share totaled $17.7 million and
$0.39, respectively, for the first nine months of 1999, compared with $16.8
million, or $0.35 per diluted share, for the first nine months of 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Total assets were approximately $1.1 billion and $1.0 billion at
September 30, 1999 and December 31, 1998, respectively. In addition,
stockholders' equity totaled $114.1 million at September 30, 1999, compared with
a deficit of $142.6 million at December 31, 1998. The increase in stockholders'
equity was primarily due to the Offering.

         The following table sets forth WESCO's outstanding indebtedness.

         During the second quarter of 1999, WESCO completed the Offering with
net proceeds of $187.6 million, and, as discussed below, refinanced its credit
agreement and accounts receivable securitization program. As a result of these
transactions, the term loans and the senior discount notes were repaid, the
prior revolving facility was refinanced and $31.5 million of convertible notes
were converted into WESCO common stock.

Revolving Credit Facility

         On June 29, 1999, WESCO Distribution, Inc. entered into a new $400
million revolving credit facility with a consortium of financial institutions.
The revolving credit facility, which matures in June 2004, consists of up to
$365 million of revolving loans denominated in US dollars and a Canadian
sublimit totaling $35 million. Borrowings under the revolving credit facility
are collateralized by substantially all the assets, excluding real property, of
WESCO Distribution, Inc. and are guaranteed by WESCO International, Inc. and
certain subsidiaries.

         Borrowings bear rates of interest equal to various indices, at WESCO's
option plus a borrowing margin. At September 30, 1999, the interest rate on
revolving credit facility borrowings was 6.81%. A commitment fee of 30 to 50
basis points per annum is due on unused portions of the revolving credit
facility. The new credit agreement is expected to reduce WESCO's borrowing
costs.

         The revolving credit facility contains various restrictive covenants
that, among other things, impose limitations on (i) dividend payments or certain
other restricted payments or investments; (ii) the incurrence of additional
indebtedness and guarantees or issuance of additional stock; (iii) creation of
liens; (iv) mergers, consolidation or sales of substantially all of WESCO's
assets (v) certain transactions among affiliates; (vi) payments by certain
subsidiaries to WESCO; and (vii) capital expenditures. In addition, the
agreements require WESCO to meet certain leverage, working capital and interest
coverage ratios.

Accounts Receivable Securitization Program

         In June 1999, WESCO and certain of its subsidiaries terminated its
previous accounts receivable securitization program and entered into a new $350
million accounts receivable securitization program ("Receivables Facility") with
another financial institution as modified in September 1999. Under the
Receivables Facility WESCO sells an undivided interest in all eligible accounts
receivable. WESCO has agreed to continue servicing the sold receivables for the
financial institution at market rates; accordingly, no servicing asset or
liability has been recorded.



                                       16
<PAGE>   18

         WESCO's liquidity needs arise from seasonal working capital
requirements, capital expenditures, debt service obligations and acquisitions.
An analysis of cash flows for the first nine months of 1999 and 1998 follows:

         Operating Activities. Cash provided by operating activities totaled
$70.7 million in the first nine months of 1999, compared to $298.7 million a
year ago. Cash provided by operations in the first nine months of 1999 and 1998
included proceeds of $60.0 million and $274.2 million, respectively, from the
sale of accounts receivable in connection with the accounts receivable
securitization program. Excluding this transaction, operating activities
provided $10.7 million in 1999 and $24.5 million in 1998. On this basis, the
period-to-period decline in operating cash flow was primarily due to increases
in working capital.

         Investing Activities. Net cash used in investing activities was $65.9
million in the first nine months of 1999, compared to $171.7 million in the same
period of 1998. Cash used for investing activities was higher in 1998 primarily
due to amounts invested in business acquisitions. Capital expenditures for the
first nine months of 1999 were $16.3 million compared to $9.4 million for first
nine months of 1998 and were for computer equipment and software, branch and
distribution center facility improvements, forklifts and delivery vehicles. The
increase from the prior year was primarily due to the replacement of computer
hardware at the branch locations.

         Financing Activities. Cash provided by financing activities totaled
$18.9 million in the first nine months of 1999 primarily due to the Offering,
offset, in part, by a net reduction in long-term debt. In the first nine months
of 1998, cash used by financing activities totaled $109.0 million primarily
reflecting the Recapitalization completed in June 1998.

         Management believes that cash generated from operations, together with
amounts available under the credit agreement and the receivables facility, will
be sufficient to meet WESCO's working capital, capital expenditures and other
cash requirements for the foreseeable future. There can be no assurance,
however, that this will be the case. Financing of acquisitions can be funded
under the existing credit agreement and may, depending on the number and size of
acquisitions, require the issuance of additional debt and equity securities.


YEAR 2000 READINESS DISCLOSURE

         The Year 2000 issue concerns the ability of automated applications to
process date-dependent processes, calculations and information by properly
interpreting the year. The Year 2000 issue may potentially impact WESCO's
business-critical computerized applications related to, among others, customer
sales, service and invoicing, purchasing, inventory management, payroll,
financing and financial accounting and reporting. In addition, other non
business-critical systems and services may also be affected. WESCO has assembled
an internal project team composed of information systems, operations, finance
and executive personnel to:

         o    assess the readiness of our systems, vendors and suppliers,
              third-party service providers, customers and financial
              institutions;

         o    replace or correct through program changes all non-compliant
              applications;

         o    develop remediation action plans for systems that may not be Year
              2000 compliant; and

         o    develop contingency plans in the event systems and services are
              not compliant.

         The readiness assessment phase of the project is complete and consisted
of a detailed assessment and testing of substantially all internal computer
systems, surveys of significant vendors and suppliers, service providers and
customers. WESCO has received, or is seeking, documentation from many external
parties, including its major suppliers, customers and service providers,
indicating their Year 2000 readiness. Over the past three years, WESCO has
invested approximately $6.0 million in new information systems to support the
growth and diversity of its business. In addition to meeting this objective,
Year 2000 compliance was also achieved in many systems.



                                       17
<PAGE>   19


         As of the date of this report, WESCO's information technology and
non-information technology systems are Year 2000 compliant. Additional testing
will continue through December 1999. The project team is also developing or
enhancing contingency plans to minimize the potential adverse effect the Year
2000 issue could have on WESCO in the event business-critical systems and
processes of WESCO or its suppliers or customers fail to be compliant. Such
contingent plans include identifying alternative suppliers or service providers.
Costs specifically associated with modifying WESCO's systems for Year 2000
compliance are expensed as incurred. Through September 30, 1999, such costs
totaled approximately $3.0 million. Costs to be incurred in the remainder of
1999 to address Year 2000 problems are estimated to be insignificant. Such costs
do not include normal system upgrades and replacements.

         Based on current information, WESCO believes that the most likely worst
case scenario to result from a Year 2000 failure by WESCO, its suppliers or
customers would be a temporary limitation in its ability to distribute
electrical products from certain operating locations or provide integrated
supply services to its customers. Based on its own efforts and information
received from third parties, WESCO does not believe that Year 2000 issues are
likely to result in significant operational problems or have a material adverse
impact on its consolidated financial position, operations or cash flow.
Nonetheless, failures of suppliers, third party vendors or customers resulting
from Year 2000 issues could result in a short-term material adverse effect.


INFLATION

         The rate of inflation, as measured by changes in the consumer price
index, did not have a material effect on the sales or operating results of
WESCO during the periods presented. However, inflation in the future could
affect WESCO's operating costs. Price changes from suppliers have historically
been consistent with inflation and have not had a material impact on WESCO's
results of operations.


SEASONALITY

         WESCO's operating results are affected by certain seasonal factors.
Sales are typically at their lowest during the first quarter due to a reduced
level of activity during the winter months. Sales increase during the warmer
months beginning in March and continuing through November. Sales drop again
slightly in December as the weather cools and also as a result of reduced level
of activity during the holiday season. As a result, WESCO reports sales and
earnings in the first quarter that are generally lower than that of the
remaining quarters.


FORWARD-LOOKING STATEMENTS

         From time to time in this report and in other written reports and oral
statements, references are made to expectations regarding future performance of
WESCO. When used in this context, the words "anticipates," "plans," "believes,"
"estimates," "intends," "expects," "projects" and similar expressions are
intended to identify forward-looking statements, although not all
forward-looking statements contain such words. Such statements including, but
not limited to, WESCO's statements regarding its business strategy, growth
strategy, productivity and profitability enhancement, new product and service
introductions and liquidity and capital resources are based on management's
beliefs, as well as on assumptions made by, and information currently available
to, management, and involve various risks and uncertainties, certain of which
are beyond WESCO's control. WESCO's actual results could differ materially from
those expressed in any forward-looking statement made by or on behalf of WESCO.
In light of these risks and uncertainties there can be no assurance that the
forward-looking information will in fact prove to be accurate. Factors that
might cause actual results to differ from such forward-looking statements
include, but are not limited to, an increase in competition, the amount of
outstanding indebtedness, the availability of appropriate acquisition
opportunities, availability of key products, functionality of information
systems, Year 2000 readiness, international operating environments and other
risks that are described in WESCO's Annual Report on Form 10-K for the year
ended December 31, 1998 which are incorporated by reference herein. WESCO has
undertaken no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.

PART II - OTHER INFORMATION

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

         On May 17, 1999, WESCO completed its initial public offering of
11,183,750 shares of common stock, $.01 par value, ("Offering") at $18.00 per
share. In connection with the Offering, certain employee rights to require WESCO
to repurchase outstanding redeemable common stock were terminated and
approximately $31.5 million of convertible notes were converted into common
stock. Proceeds from the Offering (after deducting Offering costs) totaling
$187.6 million and borrowings of approximately $65 million were used to redeem
all of the senior discount notes ($62.8 million) and to repay the revolving
credit and term loan facilities ($188.8 million). All of the proceeds of the
Offering have been applied and the Offering has terminated.

provisions of the Original Agreement shall, subject to this paragraph, be

Indemnified Party or Affected Person (as such terms are defined in the Original

shall be adjusted from time to time based upon, in part, reinvestment payments
that are made by such Purchasers.

        In consideration of the mutual agreements, provisions and covenants
contained herein, the parties hereto agree as follows:

                                   ARTICLE I.
                       AMOUNTS AND TERMS OF THE PURCHASES

         Section 1.1. PURCHASE FACILITY.

               (a) On the terms and subject to the conditions hereof, the Seller
        may, from time to time before the Facility Termination Date, request
        that the Conduit Purchasers, or, only if a Conduit Purchaser denies such
        request or is unable to fund (and provides notice of such denial or
        inability to the Seller, the Administrator and its Purchaser Agent),
        ratably request that the Related Committed Purchasers, make purchases of
        and reinvestments in undivided percentage ownership interests with
        regard to the Purchased Interest from the Seller from time to time from
        the date hereof to the Facility Termination Date. Subject to Section
        1.4(b), concerning reinvestments, at no time will a Conduit Purchaser
        have any obligation to make a purchase. Each Related Committed Purchaser
        severally hereby agrees, on the terms and subject to the conditions
        hereof, to make Purchases before the Facility Termination Date, based on
        the applicable Purchaser Group's Ratable Share of each purchase
        requested pursuant to Section 1.2(a) (each a "Purchase") (and, in the
        case of each Related Committed Purchaser, its Commitment Percentage of
        its Purchaser Group's Ratable Share of such Purchase) to the extent its
        Investment would not thereby exceed its Commitment and the Aggregate
        Investment would not (after giving effect to all Purchases on such date)
        exceed the Purchase Limit.

               (b) The Seller may, upon 30 days' written notice to the
        Administrator and each Purchaser Agent, reduce the unfunded portion of
        the Purchase Limit in whole or in part (but not below the amount which
        would cause the Group Investment of any Purchaser Group to exceed its
        Group Commitment (after giving effect to such reduction)); provided that
        each partial reduction shall be in the amount of at least $5,000,000, or
        an integral multiple of $1,000,000 in excess thereof and unless
        terminated in whole, the Purchase Limit shall in no event be reduced
        below $200,000,000. Such reduction shall at the option of the Seller be
        applied either (i) ratably to reduce the Group Commitment of each
        Purchaser Group or (ii) to terminate the Group Commitment of any one
        Purchaser Group.

         Section 1.2. MAKING PURCHASES.

               (a) Each purchase (but not reinvestment) of undivided percentage
        ownership interests with regard to the Purchased Interest hereunder
        shall be made upon the Seller's irrevocable written notice in the form
        of Annex B delivered to the Administrator and each Purchaser Agent in


                                       2
<PAGE>   6

accordance with SECTION 6.2 (which notice must be received by the Administrator
and each Purchaser Agent before 11:00 a.m., New York City time) at least three
Business Days before the requested Purchase Date, which notice shall specify:
(A) the amount requested to be paid to the Seller (such amount, which shall not
be less than $2,000,000, with respect to each Purchaser Group, being the
aggregate of the Investments of each Purchaser within such Purchaser Group,
relating to the undivided percentage ownership interest then being purchased),
(B) the date of such purchase (which shall be a Business Day), and (C) a pro
forma calculation of the Purchased Interest after giving effect to the increase
in the Aggregate Investment. If the Purchase is requested from a Conduit
Purchaser and such Conduit Purchaser determines, in its sole discretion, to make
the requested Purchase, such Conduit Purchaser shall transfer to the account of
the Seller described in Section 1.2(b), below (the "Disbursement Account"), an
amount equal to such Conduit Purchaser's Purchaser Group Ratable Share of such
Purchase on the requested Purchase Date. If the Purchase is requested from the
Related Committed Purchasers for a Purchaser Group (in the case where the
related Conduit Purchaser determined not to or was unable to make such
Purchase), subject to the terms and conditions hereof, such Related Committed
Purchasers for a Purchaser Group shall use its reasonable best efforts to
transfer the applicable Purchaser Group's Ratable Share of each Purchase (and,
in the case of each Related Committed Purchaser, its Commitment Percentage of
its Purchaser Group's Ratable Share of such Purchase) into the Disbursement
Account by no later than 1:00 p.m. (New York time) on the Purchase Date.

        (b) On the date of each Purchase, each Purchaser (or the related
Purchaser Agent on its behalf), shall make available to the Seller in same day
funds, at PNC Bank, National Association, account number 1006970651, ABA
043000096, an amount equal to the proceeds of such Purchase.

        (c) Effective on the date of each Purchase pursuant to this SECTION 1.2
and each reinvestment pursuant to SECTION 1.4, the Seller hereby sells and
assigns to the Administrator for the benefit of the Purchasers (ratably,
according to each such Purchaser's Investment) an undivided percentage ownership
interest in: (i) each Pool Receivable then existing, (ii) all Related Security
with respect to such Pool Receivables, and (iii) all Collections with respect
to, and other proceeds of, such Pool Receivables and Related Security.

        (d) To secure all of the Seller's obligations (monetary or otherwise)
under this Agreement and the other Transaction Documents to which it is a party,
whether now or hereafter existing or arising, due or to become due, direct or
indirect, absolute or contingent, the Seller hereby grants to the Administrator,
for the benefit of the Purchasers, a security interest in all of the Seller's
right, title and interest (including any undivided interest of the Seller) in,
to and under all of the following, whether now or hereafter owned, existing or
arising: (i) all Pool Receivables, (ii) all Related Security with respect to
such Pool Receivables, (iii) all Collections with respect to such Pool
Receivables, (iv) the Lock-Box Accounts and all amounts on deposit therein, and
all


                                       3
<PAGE>   7

certificates and instruments, if any, from time to time evidencing such Lock-Box
Accounts and amounts on deposit therein, (v) all rights (but none of the
obligations) of the Seller under the Sale Agreement and (vi) all proceeds of,
and all amounts received or receivable under any or all of, the foregoing
(collectively, the "Pool Assets"). The Administrator, for the benefit of the
Purchasers, shall have, with respect to the Pool Assets, and in addition to all
the other rights and remedies available to the Administrator and the Purchasers,
all the rights and remedies of a secured party under any applicable UCC.

        (e) The Seller may, with the written consent of the Administrator and
each Purchaser, add additional Persons as Purchasers (either to an existing
Purchaser Group or by creating new Purchaser Groups) or cause an existing
Purchaser to increase its Commitment in connection with a corresponding increase
in the Purchase Limit; PROVIDED, HOWEVER, that the Commitment of any Purchaser
may only be increased with the consent of such Purchaser. Each new Purchaser (or
Purchaser Group) and each Purchaser increasing its Commitment shall become a
party hereto or increase its Commitment, as the case may be, by executing and
delivering to the Administrator and the Seller an Assumption Agreement in the
form of Annex C hereto (which Assumption Agreement shall, in the case of any new
Purchaser or Purchasers be executed by each Person in such new Purchaser's
Purchaser Group).

        (f) Each Related Committed Purchaser's obligation hereunder shall be
several, such that the failure of any Related Committed Purchaser to make a
payment in connection with any purchase hereunder shall not relieve any other
Related Committed Purchaser of its obligation hereunder to make payment for any
Purchase. Further, in the event any Related Committed Purchaser fails to satisfy
its obligation to make a purchase as required hereunder, upon receipt of notice
of such failure from the Administrator (or any relevant Purchaser Agent),
subject to the limitations set forth herein, the non-defaulting Related
Committed Purchasers in such defaulting Related Committed Purchaser's Purchaser
Group shall purchase the defaulting Related Committed Purchaser's Commitment
Percentage of the related Purchase pro rata in proportion to their relative
Commitment Percentages (determined without regard to the Commitment Percentage
of the defaulting Related Committed Purchaser; it being understood that a
defaulting Related Committed Purchaser's Commitment Percentage of any Purchase
shall be first put to the Related Committed Purchasers in such defaulting
Related Committed Purchaser's Purchaser Group and thereafter if there are no
other Related Committed Purchasers in such Purchaser Group or if such other
Related Committed Purchasers are also defaulting Related Committed Purchasers,
then such defaulting Related Committed Purchaser's Commitment Percentage of such
Purchase shall be put to each other Purchaser Group ratably and applied in
accordance with this paragraph (f)). Notwithstanding anything in this paragraph
(f) to the contrary, no Related Committed Purchaser shall be required to make a
Purchase pursuant to this paragraph for an amount which would cause the
aggregate Investment of such Related Committed Purchaser (after giving effect to
such Purchase) to exceed its Commitment.

        Section 1.3. PURCHASED INTEREST COMPUTATION. The Purchased Interest
shall be initially computed on the date of the initial Purchase hereunder.
Thereafter, until the Facility Termination Date, such Purchased Interest shall
be automatically recomputed (or deemed to be recomputed) on each Business Day
other than a Termination Day. From and after the occurrence of any Termination
Day, the Purchased Interest shall (until the event(s) giving rise to such
Termination Day are satisfied or are waived by the Administrator and a Simple
Majority of the Purchasers) be deemed to be 100%. The Purchased Interest shall
become zero when the Aggregate Investment thereof and Aggregate Discount thereon
shall have been paid in full, all the amounts owed by the Seller and the
Servicer hereunder to each Purchaser, the Administrator and any other
Indemnified Party or Affected Person are paid in full, and the Servicer shall
have received the accrued Servicing Fee thereon.

        Section 1.4. SETTLEMENT PROCEDURES.

               (a) The collection of the Pool Receivables shall be administered
        by the Servicer in accordance with this Agreement. The Seller shall
        provide to the Servicer on a timely basis all information needed for
        such administration, including notice of the occurrence of any
        Termination Day and current computations of the Purchased Interest.

               (b) The Servicer shall, on each day on which Collections of Pool
        Receivables are received (or deemed received) by the Seller or the
        Servicer:

               (i) set aside and hold in trust (and shall, at the request of the
        Administrator (with the consent or at the direction of the Majority
        Purchasers), segregate in a separate account approved by the
        Administrator if, at the time of such request, there exists an Unmatured
        Termination Event or a Termination Event or if the failure to so
        segregate reasonably could be expected to cause a Material Adverse
        Effect) for the benefit of each Purchaser Group, out of such
        Collections, first, an amount equal to the Aggregate Discount accrued
        through such day for each Portion of Investment and not previously set
        aside, second, an amount equal to the fees set forth in each Purchaser
        Group Fee Letter accrued and unpaid through such day, and third, to the
        extent funds are available therefor, an amount equal to the aggregate of
        each Purchaser Group's Ratable Share of the Servicing Fee accrued
        through such day and not previously set aside,

               (ii) subject to SECTION 1.4(f), if such day is not a Termination
        Day, remit to the Seller, ratably, on behalf of each Purchaser Group,
        the remainder of such Collections. Such remainder shall, to the extent
        representing a return on the Aggregate Investment, ratably, according to
        each Purchaser's Investment, be automatically reinvested in Pool
        Receivables, and in the Related Security, Collections and other proceeds
        with respect thereto; PROVIDED, HOWEVER, that if the Purchased Interest
        would exceed 100%, then the Servicer shall not reinvest, but shall set
        aside and hold in trust for the benefit of the Purchasers (and shall, at
        the request of the Administrator (with the consent or at the direction
        of the Majority Purchasers), segregate in a separate account approved by
        the Administrator if, at the time of such request, there exists an
        Unmatured


                                       5
<PAGE>   9

Termination Event or a Termination Event or if the failure to so segregate
reasonably could be expected to cause a Material Adverse Effect) a portion of
such Collections that, together with the other Collections set aside pursuant to
this paragraph, shall equal the amount necessary to reduce the Purchased
Interest to 100%; PROVIDED, FURTHER, that (x) in the case of any Purchaser that
is a Conduit Purchaser, if such Purchaser has provided notice (a "DECLINING
NOTICE") to its Purchaser Agent, the Administrator, and the Servicer that such
Purchaser (a "DECLINING CONDUIT PURCHASER") no longer wishes Collections with
respect to any Portion of Investment funded or maintained by such Purchaser to
be reinvested pursuant to this CLAUSE (ii), and (y) in the case of any Purchaser
that has provided notice (an "EXITING NOTICE") to its Purchaser Agent of either
its refusal, pursuant to Section 1.10(a), to extend its Commitment hereunder or
of its desire pursuant to Section 1.10(b) to terminate its Commitment hereunder
(in either case, an "EXITING PURCHASER") then in either case (x) or (y), above,
such Collections shall not be reinvested and shall instead be held in trust for
the benefit of such Purchaser and applied in accordance with CLAUSE (iii),
below.

        (iii) if such day is a Termination Day (or any day following the
provision of a Declining Notice or an Exiting Notice), set aside, segregate and
hold in trust (and shall, at the request of the Administrator (with the consent
or at the direction of a Simple Majority of the Purchasers), segregate in a
separate account approved by the Administrator) for the benefit of each
Purchaser Group the entire remainder of the Collections (or in the case of a
Declining Conduit Purchaser or an Exiting Purchaser an amount equal to such
Purchaser's ratable share of such Collections based on its Investment; provided,
that solely for the purpose of determining such Purchaser's ratable share of
such Collections, such Purchaser's Investment shall be deemed to remain constant
from the date of the provision of a Declining Notice or an Exiting Notice, as
the case may be, until the date such Purchaser's Investment has been paid in
full; it being understood that if such day is also a Termination Day, such
Declining Conduit Purchaser's or Exiting Purchaser's Investment shall be
recalculated taking into account amounts received by such Purchaser in respect
of this parenthetical and thereafter Collections shall be set aside for such
Purchaser ratably in respect of its Investment (as recalculated)); provided,
that if amounts are set aside and held in trust on any Termination Day of the
type described in clause (a) of the definition of "Termination Day" (or any day
following the provision of a Declining Notice or an Exiting Notice) and,
thereafter, the conditions set forth in Section 2 of EXHIBIT II are satisfied or
waived by the Administrator and a Simple Majority of the Purchasers (or in the
case of a Declining Notice or an Exiting Notice, such Declining Notice or
Exiting Notice, as the case may be, has been revoked by the related Declining
Conduct Purchaser or Exiting Purchaser, respectively and written notice thereof
has been provided to the Administrator, the related Purchaser Agent and the
Servicer), such previously set-aside amounts shall, to the extent representing a
return on Aggregate Investment (or the Investment of the Declining Conduit
Purchaser or Exiting Purchaser, as the case may be) and ratably in accordance
with each Purchaser's Investment, be reinvested in accordance with CLAUSE (ii)
on the day of such subsequent satisfaction or waiver of conditions or revocation
of Declining Notice or Exiting Notice, as the case may be, and

        (iv) release to the Seller (subject to SECTION 1.4(f)) for its own
account any Collections in excess of: (x) amounts required to be reinvested in
accordance with clause (ii) or the proviso to CLAUSE (iii) plus (y) the amounts
that are required to be set aside pursuant to CLAUSE (i), the proviso to clause
(ii) and CLAUSE (iii) plus (z) the Seller's Share of the Servicing Fee accrued
and unpaid through such day and all reasonable and appropriate out-of-pocket
costs and expenses of the Servicer for servicing, collecting and administering
the Pool Receivables.

        (c) The Servicer shall, in accordance with the priorities set forth in
SECTION 1.4(d), below, deposit into each applicable Purchaser's account (or such
other account designated by such applicable Purchaser or its Purchaser Agent),
on each Settlement Date, Collections held for each Purchaser with respect to
such Purchaser's Portion(s) of Investment pursuant to CLAUSE (b)(i) or (f) plus
the amount of Collections then held for such Purchaser pursuant to CLAUSES
(b)(ii) and (iii) of SECTION 1.4; provided, that if WESCO or an Affiliate
thereof is the Servicer, such day is not a Termination Day and the Administrator
has not notified WESCO (or such Affiliate) that such right is revoked, WESCO (or
such Affiliate) may retain the portion of the Collections set aside pursuant to
CLAUSE (b)(i) that represents the aggregate of each Purchaser Group's Ratable
Share of the Servicing Fee. Within three Business Days of the last day of
each Yield Period with respect to any Portion of Investment, the applicable
Purchaser Agent will notify the Servicer by facsimile of the amount of the
Discount accrued with respect to each such Portion of Investment during the
related Yield Period then ending.

        (d) The Servicer shall distribute the amounts described (and at the
times set forth) in SECTION 1.4(c), as follows:

        (i) if such distribution occurs on a day that is not a Termination Day
and the Purchased Interest does not exceed 100%, first to each Purchaser Agent
ratably according to the Discount accrued during such Yield Period (for the
benefit of the relevant Purchasers within such Purchaser Agent's Purchaser
Group) in payment in full of all accrued Discount and fees (other than Servicing
Fees) with respect to each Portion of Investment maintained by such Purchasers;
it being understood that each Purchaser Agent shall distribute such amounts to
the Purchasers within its Purchaser Group ratably according to Discount, and
second, if the Servicer has set aside amounts in respect of the Servicing Fee
pursuant to CLAUSE (b)(i) and has not retained such amounts pursuant to CLAUSE
(c), to the Servicer's own account (payable in arrears on each Settlement Date)
in payment in full of the aggregate of each Purchaser Group's Ratable Share of
accrued Servicing Fees so set aside, and

        (ii) if such distribution occurs on a Termination Day or on a day when
the Purchased Interest exceeds 100%, first if WESCO or an Affiliate thereof is
not the Servicer, to the Servicer's own account in payment in full of all
accrued Servicing Fees, SECOND to each Purchaser Agent ratably according to

        of Investment funded or maintained by the Purchasers within such
        Purchaser Agent's Purchaser Group, THIRD to each Purchaser Agent ratably
        according to the aggregate of the Investment of each Purchaser in each
        such Purchaser Agent's Purchaser Group (for the benefit of the relevant
        Purchasers within such Purchaser Agent's Purchaser Group) in payment in
        full of each Purchaser's Investment (or, if such day is not a
        Termination Day, the amount necessary to reduce the Purchased Interest
        to 100%); it being understood that each Purchaser Agent shall distribute
        the amounts described in the first and second clauses of this Section
        1.4(d)(ii) to the Purchasers within its Purchaser Group ratably
        according to Discount and Investment, respectively, FOURTH, if the
        Aggregate Investment and accrued Aggregate Discount with respect to each
        Portion of Investment for all Purchaser Groups have been reduced to
        zero, and all accrued Servicing Fees payable to the Servicer (if other
        than WESCO or an Affiliate thereof) have been paid in full, to each
        Purchaser Group ratably (for the benefit of the Purchasers within such
        Purchaser Group) in accordance with its Ratable Share, the Administrator
        and any other Indemnified Party or Affected Person in payment in full of
        any other amounts owed thereto by the Seller or Servicer hereunder and,
        fifth, to the Servicer's own account (if the Servicer is WESCO or an
        Affiliate thereof) in payment in full of the Aggregate of each Purchaser
        Group's Ratable Share of all accrued Servicing Fees.

After the Aggregate Investment, Aggregate Discount, fees payable pursuant to
each Purchaser Group Fee Letter and Servicing Fees with respect to the Purchased
Interest, and any other amounts payable by the Seller and the Servicer to each
Purchaser Group, the Administrator or any other Indemnified Party or Affected
Person hereunder, have been paid in full, all additional Collections with
respect to the Purchased Interest shall be paid to the Seller for its own
account.

               (e) For the purposes of this SECTION 1.4:

               (i) if on any day the Outstanding Balance of any Pool Receivable
        is reduced or adjusted as a result of any defective, rejected, returned,
        repossessed or foreclosed goods or services, or any revision,
        cancellation, allowance, discount or other adjustment made by the Seller
        or any Affiliate of the Seller, or the Servicer or any Affiliate of the
        Servicer, or any setoff or dispute between the Seller or any Affiliate
        of the Seller, or the Servicer or any Affiliate of the Servicer and an
        Obligor, the Seller shall be deemed to have received on such day a
        Collection of such Pool Receivable in the amount of such reduction or
        adjustment;

               (ii) if on any day any of the representations or warranties in
        Section 1(g) or (n) of EXHIBIT III is not true with respect to any Pool
        Receivable, the Seller shall be deemed to have received on such day a
        Collection of such Pool Receivable in full;

               (iii) except as provided in CLAUSE (i) or (ii), or as otherwise
        required by applicable law or the relevant Contract, all Collections
        received from an Obligor of any Receivable shall be applied to the
        Receivables of such Obligor in the order of the age of such Receivables,
        starting with


                                        8
<PAGE>   12

         the oldest such Receivable, unless such Obligor designates in writing
         its payment for application to specific Receivables; and

                  (iv) if and to the extent the Administrator, any Purchaser
         Agent or any Purchaser shall be required for any reason to pay over to
         an Obligor (or any trustee, receiver, custodian or similar official in
         any Insolvency Proceeding) any amount received by it hereunder, such
         amount shall be deemed not to have been so received by such Person but
         rather to have been retained by the Seller and, accordingly, such
         Person shall have a claim against the Seller for such amount, payable
         when and to the extent that any distribution from or on behalf of such
         Obligor is made in respect thereof.

                  (f) If at any time the Seller shall wish to cause the
         reduction of Aggregate Investment (but not to commence the liquidation,
         or reduction to zero, of the entire Aggregate Investment, the Seller
         may do so as follows:

                  (i) the Seller shall give the Administrator, each Purchaser
         Agent and the Servicer (A) at least two Business Days' prior written
         notice thereof for any reduction of Aggregate Investment less than or
         equal to $10,000,000 and (B) at least ten Business Days' prior written
         notice thereof for any reduction of Aggregate Investment greater than
         $10,000,000 (in each case such notice shall include the amount of such
         proposed reduction and the proposed date on which such reduction will
         commence);

                  (ii) on the proposed date of commencement of such reduction
         and on each day thereafter, the Servicer shall cause Collections not to
         be reinvested until the amount thereof not so reinvested shall equal
         the desired amount of reduction; and

                  (iii) the Servicer shall hold such Collections in trust for
         the benefit of each Purchaser ratably according to its Investment, for
         payment to each such Purchaser (or its related Purchaser Agent for the
         benefit of such Purchaser) on the next Settlement Date with respect to
         any Portions of Investment maintained by such Purchaser immediately
         following the related current Yield Period, and the Aggregate
         Investment (together with the Investment of any related Purchaser)
         shall be deemed reduced in the amount to be paid to such Purchaser (or
         its related Purchaser Agent for the benefit of such Purchaser) only
         when in fact finally so paid;

provided that:

                  (A) the amount of any such reduction shall be not less than
         $1,000,000 for each Purchaser Group and shall be an integral multiple
         of $500,000, and the entire Aggregate Investment after giving effect to
         such reduction shall be not less than $200,000,000 and shall be in an
         integral multiple of $1,000,000 (unless the Aggregate Investment shall
         have been reduced to zero); and


                                        9
<PAGE>   13

               (B) with respect to any Portion of Investment, the Seller shall
        choose a reduction amount, and the date of commencement thereof, so that
        to the extent practicable such reduction shall commence and conclude in
        the same Yield Period.

        Section 1.5. FEES. The Seller shall pay to each Purchaser Agent for the
benefit of the related Purchasers certain fees in the amounts and on the dates
set forth in letters, dated the date hereof, each such letter (as amended,
supplemented, or otherwise modified from time to time, "a Purchaser Group Fee
Letter") in each case among the Seller, the Servicer, the Administrator and the
related Purchaser Agent.

        Section 1.6. PAYMENTS AND COMPUTATIONS, ETC.

               (a) All amounts to be paid or deposited by the Seller or the
        Servicer hereunder shall be made without reduction for offset or
        counterclaim and shall be paid or deposited no later than noon (New York
        City time) on the day when due in same day funds to the applicable
        Purchaser's account (as such account is identified in the related
        Purchaser Group Fee Letter). All amounts received after noon (New York
        City time) will be deemed to have been received on the next Business
        Day.

               (b) The Seller or the Servicer, as the case may be, shall, to the
        extent permitted by law, pay interest on any amount not paid or
        deposited by the Seller or the Servicer, as the case may be, when due
        hereunder, at an interest rate equal to 2.0% per annum above the Base
        Rate, payable on demand.

               (c) All computations of interest under CLAUSE (b) and all
        computations of Discount, fees and other amounts hereunder shall be made
        on the basis of a year of 360 (or 365 or 366, as applicable, with
        respect to Discount or other amounts calculated by reference to the Base
        Rate) days for the actual number of days elapsed. Whenever any payment
        or deposit to be made hereunder shall be due on a day other than a
        Business Day, such payment or deposit shall be made on the next Business
        Day and such extension of time shall be included in the computation of
        such payment or deposit.

        Section 1.7. INCREASED COSTS.

               (a) If any Purchaser Agent, Purchaser, Liquidity Provider, the
        Administrator or any other Program Support Provider or any of their
        respective Affiliates (each an "Affected Person") reasonably determines
        that the existence of or compliance with: (i) any law or regulation or
        any change therein or in the interpretation or application thereof, in
        each case adopted, issued or occurring after the date hereof, or (ii)
        any request, guideline or directive from any central bank or other
        Governmental Authority (whether or not having the force of law) issued
        or occurring after the date of this Agreement, affects or would affect
        the amount of capital required or expected to


                                       10
<PAGE>   14

         be maintained by such Affected Person, and such Affected Person
         determines that the amount of such capital is increased by or based
         upon the existence of any commitment to make purchases of (or otherwise
         to maintain the investment in) Pool Receivables related to this
         Agreement or any related liquidity facility, credit enhancement
         facility or other commitments of the same type, then, upon demand by
         such Affected Person (with a copy to the Administrator), the Seller
         shall promptly pay to the Administrator, for the account of such
         Affected Person, from time to time as specified by such Affected
         Person, additional amounts sufficient to compensate such Affected
         Person in the light of such circumstances, to the extent that such
         Affected Person reasonably determines such increase in capital to be
         allocable to the existence of any of such commitments. A certificate as
         to such amounts submitted to the Seller and the Administrator by such
         Affected Person shall be conclusive and binding for all purposes,
         absent manifest error.

                  (b) If, due to either: (i) the introduction of or any change
         in or in the interpretation of any law or regulation or (ii) compliance
         with any guideline or request from any central bank or other
         Governmental Authority (whether or not having the force of law), there
         shall be any increase in the cost to any Affected Person of agreeing to
         purchase or purchasing, or maintaining the ownership of, the Purchased
         Interest or any portion thereof in respect of which Discount is
         computed by reference to the Euro-Rate, then, upon demand by such
         Affected Person, the Seller shall promptly pay to such Affected Person,
         from time to time as specified by such Affected Person, additional
         amounts sufficient to compensate such Affected Person for such
         increased costs. A certificate as to such amounts submitted to the
         Seller and the Administrator by such Affected Person shall be
         conclusive and binding for all purposes, absent manifest error.

                  (c) If such increased costs affect the related Affected
         Person's portfolio of financing transactions, such Affected Person
         shall use reasonable averaging and attribution methods to allocate such
         increased costs to the transactions contemplated by this Agreement.

         Section 1.8. REQUIREMENTS OF LAW.

                  If any Affected Person reasonably determines that the
         existence of or compliance with: (a) any law or regulation or any
         change therein or in the interpretation or application thereof, in each
         case adopted, issued or occurring after the date hereof, or (b) any
         request, guideline or directive from any central bank or other
         Governmental Authority (whether or not having the force of law) issued
         or occurring after the date of this Agreement:

                  (i) does or shall subject such Affected Person to any tax of
         any kind whatsoever with respect to this Agreement, any increase in the
         Purchased Interest or any portion thereof or in the amount of such
         Person's Investment relating thereto, or does or shall change the basis
         of taxation of payments to such Affected Person on account of
         Collections, Discount or any other amounts payable hereunder (excluding
         taxes imposed on the overall pre-tax net income of such Affected


                                       11
<PAGE>   15

        Person, and franchise taxes imposed on such Affected Person, by the
        jurisdiction under the laws of which such Affected Person is organized
        or a political subdivision thereof),

               (ii) does or shall impose, modify or hold applicable any reserve,
        special deposit, compulsory loan or similar requirement against assets
        held by, or deposits or other liabilities in or for the account of,
        purchases, advances or loans by, or other credit extended by, or any
        other acquisition of funds by, any office of such Affected Person that
        are not otherwise included in the determination of the Euro-Rate or the
        Base Rate hereunder, or

              (iii) does or shall impose on such Affected Person any other
         condition,

and the result of any of the foregoing is: (A) to increase the cost to such
Affected Person of acting as Administrator or as a Purchaser Agent, or of
agreeing to purchase or purchasing or maintaining the ownership of undivided
percentage ownership interests with regard to the Purchased Interest (or
interests therein) or any Portion of Investment, or (B) to reduce any amount
receivable hereunder (whether directly or indirectly), then, in any such case,
upon demand by such Affected Person, the Seller shall promptly pay to such
Affected Person additional amounts necessary to compensate such Affected Person
for such additional cost or reduced amount receivable. All such amounts shall be
payable as incurred. A certificate from such Affected Person to the Seller and
the Administrator certifying, in reasonably specific detail, the basis for,
calculation of, and amount of such additional costs or reduced amount receivable
shall be conclusive and binding for all purposes, absent manifest error;
provided, however, that no Affected Person shall be required to disclose any
confidential or tax planning information in any such certificate.

        Section 1.9. INABILITY TO DETERMINE EURO-RATE. (a) If the Administrator
(or any Purchaser Agent) determines before the first day of any Yield Period
(which determination shall be final and conclusive) that, by reason of
circumstances affecting the interbank eurodollar market generally, deposits in
dollars (in the relevant amounts for such Yield Period) are not being offered to
banks in the interbank eurodollar market for such Yield Period, or adequate
means do not exist for ascertaining the Euro-Rate for such Yield Period, then
the Administrator shall give notice thereof to the Seller. Thereafter, until the
Administrator or such Purchaser Agent notifies the Seller that the circumstances
giving rise to such suspension no longer exist, (a) no Portion of Investment
shall be funded at the Yield Rate determined by reference to the Euro-Rate and
(b) the Discount for any outstanding Portions of Investment then funded at the
Yield Rate determined by reference to the Euro-Rate shall, on the last day of
the then current Yield Period, be converted to the Yield Rate determined by
reference to the Base Rate.

        (b) If, on or before the first day of any Yield Period, the
Administrator shall have been notified by any Purchaser, Purchaser Agent or
Liquidity Provider that, such Person has determined (which determination shall
be final and conclusive) that, any enactment, promulgation or adoption of or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by a governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by such Person with any guideline, request or directive
(whether or


                                       12
<PAGE>   16

not having the force of law) of any such authority, central bank or comparable
agency shall make it unlawful or impossible for such Person to fund or maintain
any Portion of Investment at the Yield Rate and based upon the Euro-Rate, the
Administrator shall notify the Seller thereof. Upon receipt of such notice,
until the Administrator notifies the Seller that the circumstances giving rise
to such determination no longer apply, (a) no Portion of Investment shall be
funded at the Yield Rate determined by reference to the Euro-Rate and (b) the
Discount for any outstanding Portions of Investment then funded at the Yield
Rate determined by reference to the Euro-Rate shall be converted to the Yield
Rate determined by reference to the Base Rate either (i) on the last day of the
then current Yield Period if such Person may lawfully continue to maintain such
Portion of Investment at the Yield Rate determined by reference to the Euro-Rate
to such day, or (ii) immediately, if such Person may not lawfully continue to
maintain such Portion of Investment at the Yield Rate determined by reference to
the Euro-Rate to such day.

        Section 1.10. EXTENSION OF TERMINATION DATE. (a) The Seller may advise
the Administrator and each Purchaser Agent in writing of its desire to extend
the Facility Termination Date for an additional 364 days, provided such request
is made not more than 90 days prior to, and not less than 60 days prior to, the
then current Facility Termination Date. In the event that the Purchaser Agents
are all agreeable to such extension, the Administrator shall so notify the
Seller in writing (it being understood that the Purchaser Agents may accept or
decline such a request in their sole discretion and on such terms as they may
elect) not less than 30 days prior to the then current Facility Termination Date
and the Seller, the Administrator, the Purchaser Agents and the Purchasers shall
enter into such documents as the Purchasers may deem necessary or appropriate to
reflect such extension, and all reasonable costs and expenses incurred by the
Purchasers, the Administrator and the Purchaser Agents in connection therewith
(including reasonable Attorneys' Costs) shall be paid by the Seller. In the
event the Purchaser Agents decline the request for such extension, the
Administrator shall so notify the Seller of such determination; provided,
however, that the failure of the Administrator to notify the Seller of the
determination to decline such extension shall not affect the understanding and
agreement that the Purchaser Agents shall be deemed to have refused to grant the
requested extension in the event the Administrator fails to affirmatively notify
the Seller, in writing, of their agreement to accept the requested extension.

        (b) Any Purchaser may, upon 45 days' written notice by the related
Purchaser Agent to the Administrator and the Seller, terminate its Commitment
hereunder (it being understood that upon delivery of such notice, such Purchaser
shall be an Exiting Purchaser and shall receive Collections as described in
Section 1.4(b)). Thereafter, such Purchaser's Commitment shall terminate and
such Purchaser (and in the case of a termination pursuant to this paragraph of
the Commitments of an entire Purchaser Group, the related Purchaser Agent) shall
have no further rights or obligations hereunder (except for (i) its rights to
continue to receive payments hereunder with respect to (i) Investment, Discount
and Fees in connection with its Investment in the Purchased Interest, (ii) its
rights to receive any other amounts owing to such Purchaser as an Indemnified
Party or Affected Person, (iii) any voting rights that such Purchaser
may have with respect to any Lock-Box Account and the related Lock-Box Agreement
and (iv) any other rights that expressly survive termination, in each case until
all payments owed to such Purchaser hereunder have been paid in full).

Simple Majority of the Purchasers) or shall (at the direction of a Simple
Majority of the Purchasers), by notice to the Seller, declare the Facility
Termination Date to have occurred (in which case the Facility Termination Date
shall be deemed to have occurred); provided, that automatically upon the
occurrence of any event (without any requirement for the passage of time or the
giving of notice) described in PARAGRAPH (f) of EXHIBIT V, the Facility

they may have under this Agreement, all other rights and remedies provided after
default under the New York UCC and under other applicable law, which rights and
remedies shall be cumulative.

        Section 3.1. INDEMNITIES BY THE SELLER. Without limiting any other
rights that the any Purchaser Agent, Purchaser, Liquidity Provider, the
Administrator or any Program Support Provider or any of their respective
Affiliates, employees, officers, directors, agents, counsel, successors,

however: (a) Indemnified Amounts to the extent resulting from gross negligence
or willful misconduct on the part of such Indemnified Party or its officers,
directors, agents or counsel, (b) recourse with respect to any Receivable to the

bankruptcy or lack of credit worthiness of the related Obligor, or (c) any
overall net income taxes or franchise taxes imposed on such Indemnified Party by
the jurisdiction under the laws of which such Indemnified Party is organized or
any political subdivision thereof. Without limiting or being limited by the
foregoing, and subject to the exclusions set forth


                                       14
<PAGE>   18

        it in accordance with its terms), or any other claim resulting from the
        sale of the goods or services related to such Receivable or the

<PAGE>   19

               (viii) any products liability or other claim, investigation,

               (x) the use of proceeds of purchases or reinvestments,

               (xi) any reduction in the Aggregate Investment as a result of

                                   ARTICLE IV.
                         ADMINISTRATION AND COLLECTIONS

         Section 4.1. APPOINTMENT OF THE SERVICER.

               (a) The servicing, administering and collection of the Pool
        Receivables shall be conducted by the Person so designated from time to
        time as the Servicer in accordance with this Section. Until the
        Administrator gives notice to WESCO (in accordance with this Section
        4.1) of the designation of a new Servicer, WESCO is hereby designated
        as, and hereby agrees to perform the duties and obligations of, the
        Servicer pursuant to the terms hereof. Upon the occurrence of a
        Termination Event, the Administrator may (with the consent of the
        Majority Purchasers) or shall


                                       16
<PAGE>   20

(at the direction of the Majority Purchasers) designate as Servicer any Person
(including itself) to succeed WESCO or any successor Servicer, on the condition
in each case that any such Person so designated shall agree to perform the
duties and obligations of the Servicer pursuant to the terms hereof.

        (b) Upon the designation of a successor Servicer as set forth in CLAUSE
(a), WESCO agrees that it will terminate its activities as Servicer hereunder in
a manner that the Administrator determines will facilitate the transition of the
performance of such activities to the new Servicer, and WESCO shall cooperate
with and assist such new Servicer. Such cooperation shall include access to and
transfer of related records (including all Contracts) and use by the new
Servicer of all licenses, hardware or software necessary or desirable to collect
the Pool Receivables and the Related Security.

        (c) WESCO acknowledges that, in making their decision to execute and
deliver this Agreement, the Administrator and each Purchaser Group have relied
on WESCO's agreement to act as Servicer hereunder. Accordingly, WESCO agrees
that it will not voluntarily resign as Servicer.

        (d) The Servicer may delegate its duties and obligations hereunder to
any subservicer (each a "Sub-Servicer"); provided, that, in each such
delegation: (i) such Sub-Servicer shall agree in writing to perform the duties
and obligations of the Servicer pursuant to the terms hereof, (ii) the Servicer
shall remain primarily liable for the performance of the duties and obligations
so delegated, (iii) the Seller, the Administrator and each Purchaser Group shall
have the right to look solely to the Servicer for performance, and (iv) the
terms of any agreement with any Sub-Servicer shall provide that the
Administrator may terminate such agreement upon the termination of the Servicer
hereunder by giving notice of its desire to terminate such agreement to the
Servicer (and the Servicer shall provide appropriate notice to each such
Sub-Servicer); PROVIDED, HOWEVER, that if any such delegation is to any Person
other than an Originator or an Affiliate thereof, the Administrator and the
Majority Purchasers shall have consented in writing in advance to such
delegation.

Section 4.2. DUTIES OF THE SERVICER.

        (a) The Servicer shall take or cause to be taken all such action as may
be necessary or advisable to administer and collect each Pool Receivable from
time to time, all in accordance with this Agreement and all applicable laws,
rules and regulations, with reasonable care and diligence, and in accordance
with the Credit and Collection Policies. The Servicer shall set aside, for the
account of each Purchaser Group, the amount of the Collections to which each
such Purchaser Group is entitled in accordance with ARTICLE I. The Servicer may,
in accordance with the applicable Credit and Collection Policy, extend the
maturity of any Pool Receivable (but not beyond 30 days) and extend the maturity
or adjust the Outstanding Balance of any Defaulted


                                       17
<PAGE>   21


        Receivable as the Servicer may determine to be appropriate to maximize
        Collections thereof; PROVIDED, HOWEVER, that: (i) such extension or
        adjustment shall not alter the status of such Pool Receivable as a
        Delinquent Receivable or a Defaulted Receivable or limit the rights of
        the Administrator or any Purchaser Group under this Agreement and (ii)
        if a Termination Event has occurred and WESCO or an Affiliate thereof is
        serving as the Servicer, WESCO or such Affiliate may make such extension
        or adjustment only upon the prior approval of the Administrator (with
        the consent of the Majority Purchasers). The Seller shall deliver to the
        Servicer and the Servicer shall hold for the benefit of the Seller and
        the Administrator (individually and for the benefit of each Purchaser
        Group), in accordance with their respective interests, all records and
        documents (including computer tapes or disks) with respect to each Pool
        Receivable. Notwithstanding anything to the contrary contained herein,
        the Administrator may direct the Servicer (whether the Servicer is WESCO
        or any other Person) to commence or settle any legal action to enforce
        collection of any Pool Receivable or to foreclose upon or repossess any
        Related Security; PROVIDED, HOWEVER, that no such direction may be given
        unless either: (A) a Termination Event has occurred or (B) the
        Administrator believes in good faith that failure to commence, settle or
        effect such legal action, foreclosure or repossession could adversely
        affect Receivables constituting a material portion of the Pool
        Receivables.

               (b) The Servicer shall, as soon as practicable following actual
        receipt of collected funds, turn over to the Seller the collections of
        any indebtedness that is not a Pool Receivable, less, if WESCO or an
        Affiliate thereof is not the Servicer, all reasonable and appropriate
        out-of-pocket costs and expenses of such Servicer of servicing,
        collecting and administering such collections. The Servicer, if other
        than WESCO or an Affiliate thereof, shall, as soon as practicable upon
        demand, deliver to the Seller all records in its possession that
        evidence or relate to any indebtedness that is not a Pool Receivable,
        and copies of records in its possession that evidence or relate to any
        indebtedness that is a Pool Receivable.

               (c) The Servicer's obligations hereunder shall terminate on the
        later of: (i) the Facility Termination Date and (ii) the date on which
        all amounts required to be paid to the Purchaser Agents, each Purchaser,
        the Administrator and any other Indemnified Party or Affected Person
        hereunder shall have been paid in full.

        After such termination, if WESCO or an Affiliate thereof was not the
Servicer on the date of such termination, the Servicer shall promptly deliver to
the Seller all books, records and related materials that the Seller previously
provided to the Servicer, or that have been obtained by the Servicer, in
connection with this Agreement.

        Section 4.3. LOCK-BOX ACCOUNT ARRANGEMENTS. Within 45 days from
the initial purchase hereunder, the Seller shall have entered into Lock-Box
Agreements with all of the Lock-Box Banks and delivered original counterparts of
each to the Administrator and each Purchaser Agent. Upon the occurrence of a
Termination Event, the Administrator may (with the consent of a Simple Majority
of


                                       18
<PAGE>   22

the Purchasers) or shall (upon the direction of a Simple Majority of the
Purchasers) at any time thereafter give notice to each Lock-Box Bank that the
Administrator is exercising its rights under the Lock-Box Agreements to do any
or all of the following: (a) to have the exclusive ownership and control of the
Lock-Box Accounts transferred to the Administrator (for the benefit of the
Purchasers) and to exercise exclusive dominion and control over the funds
deposited therein, (b) to have the proceeds that are sent to the respective
Lock-Box Accounts redirected pursuant to the Administrator's instructions rather
than deposited in the applicable Lock-Box Account, and (c) to take any or all
other actions permitted under the applicable Lock-Box Agreement. The Seller
hereby agrees that if the Administrator at any time takes any action set forth
in the preceding sentence, the Administrator shall have exclusive control (for
the benefit of the Purchasers) of the proceeds (including Collections) of all
Pool Receivables and the Seller hereby further agrees to take any other action
that the Administrator or any Purchaser Agent may reasonably request to transfer
such control. Any proceeds of Pool Receivables received by the Seller or the
Servicer thereafter shall be sent immediately to the Administrator. The parties
hereto hereby acknowledge that if at any time the Administrator takes control of
any Lock-Box Account, the Administrator shall not have any rights to the funds
therein in excess of the unpaid amounts due to the Administrator, the Purchaser
Groups, any Indemnified Party or any other Person hereunder, and the
Administrator shall distribute or cause to be distributed such funds in
accordance with SECTION 4.2(b) and ARTICLE I (in each case as if such funds were
held by the Servicer thereunder).

        Section        4.4.   ENFORCEMENT RIGHTS.

               (a) At any time following the occurrence of a Termination Event:

               (i) the Administrator may (with the consent or at the direction
        of the Majority Purchasers) direct the Obligors that payment of all
        amounts payable under any Pool Receivable is to be made directly to the
        Administrator or its designee,

               (ii) the Administrator may (with the consent or at the direction
        of the Majority Purchasers) instruct the Seller or the Servicer to give
        notice of the Purchaser Groups' interest in Pool Receivables to each
        Obligor, which notice shall direct that payments be made directly to the
        Administrator or its designee (on behalf of such Purchaser Groups), and
        the Seller or the Servicer, as the case may be, shall give such notice
        at the expense of the Seller or the Servicer, as the case may be;
        PROVIDED, that if the Seller or the Servicer, as the case may be, fails
        to so notify each Obligor, the Administrator (at the Seller's or the
        Servicer's, as the case may be, expense) may so notify the Obligors, and

               (iii) the Administrator may (with the consent or at the direction
        of the Majority Purchasers) request the Servicer to, and upon such
        request the Servicer shall: (A) assemble all of the records necessary or
        desirable to collect the Pool Receivables and the Related Security, and
        transfer or license to a successor Servicer the use of all software
        necessary or desirable to collect the Pool Receivables and the Related
        Security, and make the same available to the Administrator


                                       19
<PAGE>   23

        or its designee (for the benefit of the Purchasers) at a place selected
        by the Administrator, and (B) segregate all cash, checks and other
        instruments received by it from time to time constituting Collections in
        a manner acceptable to the Administrator and, promptly upon receipt,
        remit all such cash, checks and instruments, duly endorsed or with duly
        executed instruments of transfer, to the Administrator or its designee.

               (b) The Seller hereby authorizes the Administrator (on behalf of
        each Purchaser Group), and irrevocably appoints the Administrator as its
        attorney-in-fact with full power of substitution and with full authority
        in the place and stead of the Seller, which appointment is coupled with
        an interest, to take any and all steps in the name of the Seller and on
        behalf of the Seller necessary or desirable, in the determination of the
        Administrator, after the occurrence of a Termination Event, to collect
        any and all amounts or portions thereof due under any and all Pool
        Assets, including endorsing the name of the Seller on checks and other
        instruments representing Collections and enforcing such Pool Assets.
        Notwithstanding anything to the contrary contained in this subsection,
        none of the powers conferred upon such attorney-in-fact pursuant to the
        preceding sentence shall subject such attorney-in-fact to any liability
        if any action taken by it shall prove to be inadequate or invalid, nor
        shall they confer any obligations upon such attorney-in-fact in any
        manner whatsoever.

        Section 4.5. RESPONSIBILITIES OF THE SELLER.

               (a) Anything herein to the contrary notwithstanding, the Seller
        shall: (i) perform all of its obligations, if any, under the Contracts
        related to the Pool Receivables to the same extent as if interests in
        such Pool Receivables had not been transferred hereunder, and the
        exercise by the Administrator, the Purchaser Agents or the Purchasers of
        their respective rights hereunder shall not relieve the Seller from such
        obligations, and (ii) pay when due any taxes, including any sales taxes
        payable in connection with the Pool Receivables and their creation and
        satisfaction. The Administrator, the Purchaser Agents or any of the
        Purchasers shall not have any obligation or liability with respect to
        any Pool Asset, nor shall any of them be obligated to perform any of the
        obligations of the Seller, Servicer, WESCO or the Originators
        thereunder.

               (b) WESCO hereby irrevocably agrees that if at any time it shall
        cease to be the Servicer hereunder, it shall act (if the then-current
        Servicer so requests) as the data-processing agent of the Servicer and,
        in such capacity, WESCO shall conduct the data-processing functions of
        the administration of the Receivables and the Collections thereon in
        substantially the same way that WESCO conducted such data-processing
        functions while it acted as the Servicer.

         Section 4.6. SERVICING FEE. (a) Subject to CLAUSE (b), the Servicer
shall be paid a fee (the "Servicing Fee") equal to 0.50% PER ANNUM of the daily
average aggregate Outstanding Balance of the Pool Receivables. The Aggregate of
each Purchaser Group's Ratable Share of such fee shall be paid through


                                       20
<PAGE>   24

the distributions contemplated by SECTION 1.4(d), and the Seller's Share of such
fee shall be paid by the Seller.

        (b) If the Servicer ceases to be WESCO or an Affiliate thereof, the
servicing fee shall be the greater of: (i) the amount calculated pursuant to
CLAUSE (a), and (ii) an alternative amount specified by the successor Servicer
not to exceed 110% of the aggregate reasonable costs and expenses incurred by
such successor Servicer in connection with the performance of its obligations as
Servicer.

                                   ARTICLE V.
                                   THE AGENTS

liability or which is contrary to the provision of any Transaction Document or
applicable law.

        (b) Each Purchaser hereby irrevocably designates and appoints the
respective institution identified as the Purchaser Agent for such Purchaser's
Purchaser Group on the signature pages hereto or in the Assumption Agreement or
Transfer Supplement pursuant to which such Purchaser becomes a party hereto, and
each authorizes such Purchaser Agent to take such action on its behalf under the
provisions of this Agreement and to exercise such powers and perform such duties
as are expressly delegated to such Purchaser Agent by the terms of this
Agreement, if any, together with such other powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary elsewhere in this
Agreement, no Purchaser Agent shall have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any
Purchaser or other Purchaser Agent or the Administrator, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities on
the part of such Purchaser Agent shall be read into this Agreement or otherwise
exist against such Purchaser Agent.

        (c) Except as otherwise specifically provided in this Agreement, the
provisions of this Article V are solely for the benefit of the Purchaser Agents,
the Administrator and the Purchasers, and none of the


                                       21
<PAGE>   25

Seller or Servicer shall have any rights as a third-party beneficiary or
otherwise under any of the provisions of this Article V, except that this
Article V shall not affect any obligations which any Purchaser Agent, the
Administrator or any Purchaser may have to the Seller or the Servicer under the
other provisions of this Agreement. Furthermore, no Purchaser shall have any
rights as a third-party beneficiary or otherwise under any of the provisions
hereof in respect of a Purchaser Agent which is not the Purchaser Agent for such
Purchaser.

        (d) In performing its functions and duties hereunder, the Administrator
shall act solely as the agent of the Purchasers and the Purchaser Agents and
does not assume nor shall be deemed to have assumed any obligation or
relationship of trust or agency with or for the Seller or Servicer or any of
their successors and assigns. In performing its functions and duties hereunder,
each Purchaser Agent shall act solely as the agent of its respective Purchaser
and does not assume nor shall be deemed to have assumed any obligation or
relationship of trust or agency with or for the Seller, the Servicer, any other
Purchaser, any other Purchaser Agent or the Administrator, or any of their
respective successors and assigns.

        Section 5.2. DELEGATION OF DUTIES. The Administrator may execute any of
its duties through agents or attorneys-in-fact and shall be entitled to advice
of counsel concerning all matters pertaining to such duties. The Administrator
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

        Section 5.3. EXCULPATORY PROVISIONS. None of the Purchaser Agents, the
Administrator or any of their directors, officers, agents or employees shall be
liable for any action taken or omitted (i) with the consent or at the direction
of the Majority Purchasers (or in the case of any Purchaser Agent, the
Purchasers within its Purchaser Group that have a majority of the aggregate
Commitment of such Purchaser Group) or (ii) in the absence of such Person's
gross negligence or willful misconduct. The Administrator shall not be
responsible to any Purchaser, Purchaser Agent or other Person for (i) any
recitals, representations, warranties or other statements made by the Seller,
Servicer, or any of their Affiliates, (ii) the value, validity, effectiveness,
genuineness, enforceability or sufficiency of any Transaction Document, (iii)
any failure of the Seller, any Originator or any of their Affiliates to perform
any obligation or (iv) the satisfaction of any condition specified in Exhibit
II. The Administrator shall not have any obligation to any Purchaser or
Purchaser Agent to ascertain or inquire about the observance or performance of
any agreement contained in any Transaction Document or to inspect the
properties, books or records of the Seller, Servicer, Originator or any of their
Affiliates.

        Section 5.4. RELIANCE BY AGENTS. Each Purchaser Agent and the
Administrator shall in all cases be entitled to rely, and shall be fully
protected in relying, upon any document or other writing or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person and upon advice and statements of legal counsel (including
counsel to the Seller), independent accountants and other experts selected by
the Administrator. Each Purchaser Agent and the Administrator shall in all cases
be fully justified in failing or refusing to take any action under any
Transaction Document unless it shall first receive such advice or concurrence of
the Majority Purchasers (or in the case of any


                                       22
<PAGE>   26

Purchaser Agent, the Purchasers within its Purchaser Group that have a majority
of the aggregate Commitment of such Purchaser Group), and assurance of its
indemnification, as it deems appropriate.

        (b) The Administrator shall in all cases be fully protected in acting,
or in refraining from acting, under this Agreement in accordance with a request
of the Majority Purchasers or the Purchaser Agents, and such request and any
action taken or failure to act pursuant thereto shall be binding upon all
Purchasers, the Administrator and Purchaser Agents.

        (c) The Purchasers within each Purchaser Group with a majority of the
Commitment of such Purchaser Group shall be entitled to request or direct the
related Purchaser Agent to take action, or refrain from taking action, under
this Agreement on behalf of such Purchasers. Such Purchaser Agent shall in all
cases be fully protected in acting, or in refraining from acting, under this
Agreement in accordance with a request of such majority Purchasers, and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all of such Purchaser Agent's Purchasers.

        (d) Unless otherwise advised in writing by a Purchaser Agent or by any
Purchaser on whose behalf such Purchaser Agent is purportedly acting, each party
to this Agreement may assume that (i) such Purchaser Agent is acting for the
benefit of each of the Purchasers in respect of which such Purchaser Agent is
identified as being the "Purchaser Agent" in the definition of "Purchaser Agent"
hereto, as well as for the benefit of each assignee or other transferee from any
such Person, and (ii) each action taken by such Purchaser Agent has been duly
authorized and approved by all necessary action on the part of the Purchasers on
whose behalf it is purportedly acting. Each Purchaser Agent and its Purchaser(s)
shall agree amongst themselves as to the circumstances and procedures for
removal, resignation and replacement of such Purchaser Agent.

        Section 5.5. [Intentionally Omitted].

        Section 5.6. NOTICE OF TERMINATION EVENTS. Neither any Purchaser Agent
nor the Administrator shall be deemed to have knowledge or notice of the
occurrence of any Termination Event or Unmatured Termination Event unless such
Administrator has received notice from any Purchaser, Purchaser Agent, the
Servicer or the Seller stating that a Termination Event or Unmatured Termination
Event has occurred hereunder and describing such Termination Event or Unmatured
Termination Event. In the event that the Administrator receives such a notice,
it shall promptly give notice thereof to each Purchaser Agent whereupon each
such Purchaser Agent shall promptly give notice thereof to its Purchasers. In
the event that a Purchaser Agent receives such a notice (other than from the
Administrator), it shall promptly give notice thereof to the Administrator. The
Administrator shall take such action concerning a Termination Event or Unmatured
Termination Event as may be directed by the Majority Purchasers unless such
action otherwise requires the consent of all Purchasers), but until the
Administrator receives such directions, the Administrator may (but shall not be
obligated to) take such action, or refrain from taking such action, as the
Administrator deems advisable and in the best interests of the Purchasers and
Purchaser Agents.

        Section 5.7. NON-RELIANCE ON ADMINISTRATOR, PURCHASER AGENTS AND OTHER
PURCHASERS. Each Purchaser expressly acknowledges that none of the
Administrator, the Purchaser Agents nor any of their respective officers,
directors, employees, agents, attorneys-in-fact or Affiliates has made any
representations or warranties to it and that no act by the Administrator, or any
Purchaser Agent hereafter taken, including any review of the affairs of the
Seller, WESCO, Servicer or any Originator, shall be deemed to constitute any
representation or warranty by the Administrator or such Purchaser Agent, as
applicable. Each Purchaser represents and warrants to the Administrator and the
Purchaser Agents that, independently and without reliance upon the
Administrator, Purchaser Agents or any other Purchaser and based on such
documents and information as it has deemed appropriate, it has made and will
continue to make its own appraisal of and investigation into the business,
operations, property, prospects, financial and other conditions and
creditworthiness of the Seller, WESCO, Servicer or the Originators, and the
Receivables and its own decision to enter into this Agreement and to take, or
omit, action under any Transaction Document. Except for items specifically
required to be delivered hereunder, the Administrator shall not have any duty or
responsibility to provide any Purchaser Agent with any information concerning
the Seller, WESCO, Servicer or the Originators or any of their Affiliates that
comes into the possession of the Administrator or any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates.

        Section 5.8. ADMINISTRATORS AND AFFILIATES. Each of the Purchasers and
the Administrator and their Affiliates may extend credit to, accept deposits
from and generally engage in any kind of banking, trust, debt, entity or other
business with the Seller, WESCO, Servicer or any Originator or any of their
Affiliates and PNC Bank, National Association may exercise or refrain from
exercising its rights and powers as if it were not the Administrator. With
respect to the acquisition of the Eligible Receivables pursuant to this
Agreement, each of the Purchaser Agents and the Administrator shall have the
same rights and powers under this Agreement as any Purchaser and may exercise
the same as though it were not such an agent, and the terms "Purchaser" and
"Purchasers" shall include each of the Purchaser Agents and the Administrator in
their individual capacities.

        Section 5.9. INDEMNIFICATION. Each Purchaser Group (it being understood
that, in the case of the Purchaser Group including TRFCO, the provisions of this
SECTION 5.9 shall only apply to each Purchaser therein) shall indemnify and hold
harmless the Administrator (but solely in its capacity as Administrator) and its
officers, directors, employees, representatives and agents (to the extent not
reimbursed by the Seller, WESCO or Servicer and without limiting the obligation
of the Seller, WESCO or Servicer to do so), ratably in accordance with its
Ratable Share from and against any and all liabilities, obligations, losses,
damages, penalties, judgments, settlements, costs, expenses and disbursements of
any kind whatsoever (including in connection with any investigative or
threatened proceeding, whether or not the Administrator or such Person shall be
designated a party thereto) that may at any time be imposed on, incurred by or
asserted against the Administrator or such Person as a result of, or related to,
any of the transactions contemplated by the Transaction Documents or the
execution, delivery or performance of the Transaction Documents or any other
document furnished in connection therewith (but excluding any such liabilities,
obligations, losses, damages, penalties, judgments, settlements, costs, expenses
or disbursements resulting solely from the gross negligence or willful
misconduct of the Administrator or such Person as finally


                                       24
<PAGE>   28

determined by a court of competent jurisdiction); PROVIDED, that in the case of
each Purchaser that is a commercial paper conduit, such indemnity shall be
provided solely to the extent of amounts received by such Purchaser under this
Agreement which exceed the amounts required to repay such Purchaser's
outstanding Notes. Notwithstanding anything in this SECTION 5.9 to the contrary,
each of the Administrator, each Purchaser Agent and each Purchaser hereby
covenants and agrees that it shall not institute against, or join any other
Person in instituting against, any Conduit Purchaser any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding or other
proceedings under any federal or state bankruptcy or similar law, for one year
and a day after the latest maturing Note issued by such Conduit Purchaser is
paid in full.

        Section 5.10. SUCCESSOR ADMINISTRATOR. The Administrator may, upon at
least five (5) days notice to the Seller and each Purchaser and Purchaser Agent,
resign as Administrator. Such resignation shall not become effective until a
successor agent is appointed by the Majority Purchasers and has accepted such
appointment. Upon such acceptance of its appointment as Administrator hereunder
by a successor Administrator, such successor Administrator shall succeed to and
become vested with all the rights and duties of the retiring Administrator, and
the retiring Administrator shall be discharged from its duties and obligations
under the Transaction Documents. After any retiring Administrator's resignation
hereunder, the provisions of SECTIONS 3.1 and 3.2 and this Article V shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
the Administrator.

                                   ARTICLE VI.
                                  MISCELLANEOUS

        Section 6.1. AMENDMENTS, ETC. No amendment or waiver of any provision of
this Agreement or any other Transaction Document, or consent to any departure by
the Seller or the Servicer therefrom, shall be effective unless in a writing
signed by the Administrator and each of the Majority Purchasers, and, in the
case of any amendment, by the other parties thereto; and then such amendment,
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; PROVIDED, HOWEVER, that no such material
amendment shall be effective until both Moody's and Standard & Poor's have
notified the Servicer and the Administrator in writing that such action will not
result in a reduction or withdrawal of the rating of any Notes; PROVIDED,
FURTHER that no such amendment or waiver shall, without the consent of each
affected Purchaser, (A) extend the date of any payment or deposit of Collections
by the Seller or the Servicer, (B) reduce the rate or extend the time of payment
of Yield, (C) reduce any fees payable to the Administrator, any Purchaser Agent
or any Purchaser pursuant to the applicable Purchaser Group Fee Letter, (D)
change the amount of Capital of any Purchaser, any Purchaser's pro rata share of
the Purchased Interest or any Related Committed Purchaser's Commitment, (E)
amend, modify or waive any provision of the definition of "Majority Purchaser"
or this Section 6.1, (F) consent to or permit the assignment or transfer by the
Seller of any of its rights and obligations under this Agreement, (G) change the
definition of "Eligible Receivable," "Loss Reserve," "Loss Reserve Percentage,"


                                       25
<PAGE>   29

"Dilution Reserve," "Dilution Reserve Percentage" or "Termination Event", (H)
amend or modify any defined term (or any defined term used directly or
indirectly in such defined term) used in clauses (A) through (G) above in a
manner that would circumvent the intention of the restrictions set forth in such
clauses, or (I) otherwise materially and adversely affect the rights of any such
Purchaser hereunder. No failure on the part of the Purchasers or the
Administrator to exercise, and no delay in exercising any right hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right.

        Section 6.2. NOTICES, ETC. All notices and other communications
hereunder shall, unless otherwise stated herein, be in writing (which shall
include facsimile communication) and be sent or delivered to each party hereto
at its address set forth under its name on the signature pages hereof (or in any
Assumption Agreement pursuant to which it became a party hereto) or at such
other address as shall be designated by such party in a written notice to the
other parties hereto. Notices and communications by facsimile shall be effective
when sent (and shall be followed by hard copy sent by first class mail), and
notices and communications sent by other means shall be effective when received.

        Section 6.3. SUCCESSORS AND ASSIGNS; PARTICIPATIONS; ASSIGNMENTS.

        (a) SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns. Except as otherwise provided herein, the Seller may not assign or
transfer any of its rights or delegate any of its duties hereunder or under any
Transaction Document without the prior consent of the Administrator, the
Purchaser Agents and the Purchasers.

        (b) PARTICIPATIONS. Any Purchaser may sell to one or more Persons (each
a "Participant") participating interests in the interests of such Purchaser
hereunder; provided, however, that no Purchaser shall grant any participation
under which the Participant shall have rights to approve any amendment to or
waiver of this Agreement or any other Transaction Document. Such Purchaser shall
remain solely responsible for performing its obligations hereunder, and the
Seller, each Purchaser Agent and the Administrator shall continue to deal solely
and directly with such Purchaser in connection with such Purchaser's rights and
obligations hereunder. A Purchaser shall not agree with a Participant to
restrict such Purchaser's right to agree to any amendment hereto, except
amendments that require the consent of all Purchasers.

        (c) ASSIGNMENTS BY CERTAIN RELATED COMMITTED PURCHASERS. Any Related
Committed Purchaser may assign to one or more Persons (each a "Purchasing
Related Committed Purchaser"), reasonably acceptable to the related Purchaser
Agent in its sole discretion, any portion of its Commitment pursuant to a
supplement hereto, substantially in the form of Annex E with any changes as have
been approved by the parties thereto (a "Transfer Supplement"), executed by each
such Purchasing Related Committed Purchaser, such selling Related Committed
Purchaser, such related Purchaser Agent. Any such assignment by Related
Committed Purchaser cannot be for an amount less than $25,000,000. Upon (i)


                                       26
<PAGE>   30

the execution of the Transfer Supplement, (ii) delivery of an executed copy
thereof to the Seller, such related Purchaser Agent and the Administrator and
(iii) payment by the Purchasing Related Committed Purchaser to the selling
Related Committed Purchaser of the agreed purchase price, such selling Related
Committed Purchaser shall be released from its obligations hereunder to the
extent of such assignment and such Purchasing Related Committed Purchaser shall
for all purposes be a Related Committed Purchaser party hereto and shall have
all the rights and obligations of a Related Committed Purchaser hereunder to the
same extent as if it were an original party hereto. The amount of the Commitment
of the selling Related Committed Purchaser allocable to such Purchasing Related
Committed Purchaser shall be equal to the amount of the Commitment of the
selling Related Committed Purchaser transferred regardless of the purchase price
paid therefor. The Transfer Supplement shall be an amendment hereof only to the
extent necessary to reflect the addition of such Purchasing Related Committed
Purchaser as a "Related Committed Purchaser" and any resulting adjustment of the
selling Related Committed Purchaser's Commitment.

        (d) Replaceable Related Committed Purchaser. If any Related Committed
Purchaser (a "Replaceable Related Committed Purchaser") shall (i) petition the
Seller for any amounts under Section 1.7 or 1.8 or (ii) cease to have a
short-term debt rating of "A-1" by Standard & Poor's and "P-1" by Moody's (if
such a rating is required by the related Purchaser's securitization program),
the related Purchaser Agent may designate a replacement financial institution (a
"Replacement Related Committed Purchaser"), to which such Replaceable Related
Committed Purchaser shall, subject to its receipt of an amount equal to the
aggregate outstanding principal balance of its Investment and accrued and unpaid
Discount thereon (and, if applicable, its receipt (unless a later date for the
remittance thereof shall be agreed upon by the Seller and such Replaceable
Related Committed Purchaser) of all amounts claimed under Section 1.7 and/or
1.8) promptly assign all of its rights, obligations and Commitment hereunder,
together with all of its right, title and interest in, to and under the
Purchased Interest allocable to it, to the Replacement Related Committed
Purchaser in accordance with Section 6.3(c), above. Once such assignment becomes
effective, the Replacement Related Committed Purchaser shall be deemed to be a
"Related Committed Purchaser" for all purposes hereof and such Replaceable
Related Committed Purchaser shall cease to be "Related Committed Purchaser" for
all purposes hereof and shall have no further rights or obligations hereunder.

        (e) Assignment by Conduit Purchasers. Each party hereto agrees and
consents (i) to any Conduit Purchaser's assignment, participation, grant of
security interests in or other transfers of any portion of, or any of its
beneficial interest in, the Purchased Interest (or portion thereof), including
without limitation to any collateral agent in connection with its commercial
paper program and (ii) to the complete assignment by any Conduit Purchaser of
all of its rights and obligations hereunder to any other Person, and upon such
assignment such Conduit Purchaser shall be released from all obligations and
duties, if any, hereunder; provided, however, that such Conduit Purchaser may
not, without the prior consent of its Related Committed Purchasers, make any
such transfer of its rights hereunder unless the assignee (i) is principally
engaged in the purchase of assets similar to the assets being purchased
hereunder, (ii) has as its Purchaser Agent the Purchaser Agent of the assigning
Conduit Purchaser and (iii) issues commercial paper or other Notes with credit
ratings substantially comparable to the ratings of the assigning Conduit
Purchaser. Any assigning Conduit Purchaser shall deliver to any assignee a
supplement hereto, substantially in the form of


                                       27
<PAGE>   31

Annex D with any changes as have been approved by the parties thereto (also, a
"Transfer Supplement"), duly executed by such Conduit Purchaser, assigning any
portion of its interest in the Purchased Interest to its assignee. Such Conduit
Purchaser shall promptly (i) notify each of the other parties hereto of such
assignment and (ii) take all further action that the assignee reasonably
requests in order to evidence the assignee's right, title and interest in such
interest in the Purchased Interest and to enable the assignee to exercise or
enforce any rights of such Conduit Purchaser hereunder. Upon the assignment of
any portion of its interest in the Purchased Interest, the assignee shall have
all of the rights hereunder with respect to such interest (except that the
Discount therefor shall thereafter accrue at the rate, determined with respect
to the assigning Conduit Purchaser unless the Seller, the related Purchaser
Agent and the assignee shall have agreed upon a different Discount).

        (f) Opinions of Counsel. If required by the Administrator or the
applicable Purchaser Agent or to maintain the ratings of any Conduit Purchaser,
each Transfer Supplement must be accompanied by an opinion of counsel of the
assignee as to such matters as the Administrator or such Purchaser Agent may
reasonably request.

        Section 6.4. COSTS, EXPENSES AND TAXES. In addition to the rights of
indemnification granted under SECTION 3.1, the Seller agrees to pay on demand
(which demand shall be accompanied by documentation thereof in reasonable
detail) all reasonable costs and expenses in connection with the preparation,
execution, delivery and administration (including periodic internal audits by
the Administrator of Pool Receivables) of this Agreement, the other Transaction
Documents and the other documents and agreements to be delivered hereunder (and
all reasonable costs and expenses in connection with any amendment, waiver or
modification of any thereof), including: (i) Attorney Costs for the
Administrator, each Purchaser Group and their respective Affiliates and agents
with respect thereto and with respect to advising the Administrator, each
Purchaser Group and their respective Affiliates and agents as to their rights
and remedies under this Agreement and the other Transaction Documents, and (ii)
all reasonable costs and expenses (including Attorney Costs), if any, of the
Administrator, each Purchaser Group and their respective Affiliates and agents
in connection with the enforcement of this Agreement and the other Transaction
Documents.

               (a) In addition, the Seller shall pay on demand any and all stamp
        and other taxes and fees payable in connection with the execution,
        delivery, filing and recording of this Agreement or the other documents
        or agreements to be delivered hereunder, and agrees to save each
        Indemnified Party harmless from and against any liabilities with respect
        to or resulting from any delay in paying or omission to pay such taxes
        and fees.

        Section 6.5. NO PROCEEDINGS; LIMITATION ON PAYMENTS. Each of the Seller,
WESCO, the Servicer, the Administrator, the Purchaser Agents, the Purchasers,
each assignee of the Purchased Interest or any interest therein, and each Person
that enters into a commitment to purchase the Purchased Interest or interests
therein, hereby covenants and agrees that it will not institute against, or join
any other Person in instituting against, any Conduit Purchaser any bankruptcy,
reorganization, arrangement, insolvency or


                                       28
<PAGE>   32

liquidation proceeding, or other proceeding under any federal or state
bankruptcy or similar law, for one year and one day after the latest maturing
Note issued by such Conduit Purchaser is paid in full. The provision of this
SECTION 6.5 shall survive any termination of this Agreement.

        Section 6.6. GOVERNING LAW AND JURISDICTION.

               (a) THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER
        AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING
        FOR SUCH PURPOSE SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS
        LAW OF THE STATE OF NEW YORK) EXCEPT TO THE EXTENT THAT THE VALIDITY OR
        PERFECTION OF A SECURITY INTEREST OR REMEDIES HEREUNDER, IN RESPECT OF
        ANY PARTICULAR COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION
        OTHER THAN THE STATE OF NEW YORK.

               (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT
        MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED
        STATES FOR THE SOUTHERN DISTRICT OF NEW YORK; AND, BY EXECUTION AND
        DELIVERY OF THIS AGREEMENT, EACH OF THE PARTIES HERETO CONSENTS, FOR
        ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION
        OF THOSE COURTS. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES, TO THE
        MAXIMUM EXTENT PERMITTED BY LAW, ANY OBJECTION, INCLUDING ANY OBJECTION
        TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS,
        THAT IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
        PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY
        DOCUMENT RELATED HERETO. EACH OF THE PARTIES HERETO WAIVES PERSONAL
        SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH SERVICE MAY BE
        MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

        Section 6.7. EXECUTION IN COUNTERPARTS. This Agreement may be executed
in any number of counterparts, each of which, when so executed, shall be deemed
to be an original, and all of which, when taken together, shall constitute one
and the same agreement.

        Section 6.8. SURVIVAL OF TERMINATION. The provisions of SECTIONS 1.7,
1.8, 3.1, 3.2, 6.4, 6.5, 6.6, 6.9 and 6.14 shall survive any termination of this
Agreement.

        Section 6.9. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO WAIVES
THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED
UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE
BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER


                                       29
<PAGE>   33

PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR
OTHERWISE. EACH OF THE PARTIES HERETO AGREES THAT ANY SUCH CLAIM OR CAUSE OF
ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE
FOREGOING, EACH OF THE PARTIES HERETO FURTHER AGREES THAT ITS RESPECTIVE RIGHT
TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION,
COUNTERCLAIM OR OTHER PROCEEDING THAT SEEKS, IN WHOLE OR IN PART, TO CHALLENGE
THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR ANY PROVISION HEREOF. THIS
WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT.

        Section 6.10. SHARING OF RECOVERIES. Each Purchaser agrees that if it
receives any recovery, through set-off, judicial action or otherwise, on any
amount payable or recoverable hereunder in a greater proportion than should have
been received hereunder or otherwise inconsistent with the provisions hereof,
then the recipient of such recovery shall purchase for cash an interest in
amounts owing to the other Purchasers (as return of Investment or otherwise),
without representation or warranty except for the representation and warranty
that such interest is being sold by each such other Purchaser free and clear of
any Adverse Claim created or granted by such other Purchaser, in the amount
necessary to create proportional participation by the Purchaser in such
recovery. If all or any portion of such amount is thereafter recovered from the
recipient, such purchase shall be rescinded and the purchase price restored to
the extent of such recovery, but without interest.

        Section 6.11. RIGHT OF SETOFF. During a Termination Event, each
Purchaser is hereby authorized (in addition to any other rights it may have) to
setoff, appropriate and apply (without presentment, demand, protest or other
notice which are hereby expressly waived) any deposits and any other
indebtedness held or owing by such Purchaser (including by any branches or
agencies of such Purchaser) to, or for the account of, the Seller against
amounts owing by the Seller hereunder (even if contingent or unmatured).

        Section 6.12. ENTIRE AGREEMENT. This Agreement and the other Transaction
Documents embody the entire agreement and understanding between the parties
hereto, and supersede all prior or contemporaneous agreements and understandings
of such Persons, verbal or written, relating to the subject matter hereof and
thereof.

any Exhibit, Schedule or Annex hereto are for convenience of reference only and

Purchaser Agent and each Purchaser under the Transaction Documents are solely

arising out of the willful misconduct or gross negligence of the Administrator,
any Purchaser Agent or any Purchaser, no claim may be made by the Seller or the
Servicer


                                       30

or any other Person against the Administrator, any Purchaser Agent or any
Purchaser or their respective Affiliates, directors, officers, employees,
attorneys or agents for any special, indirect, consequential or punitive damages
in respect of any claim for breach of contract or any other theory of liability
arising out of or related to the transactions contemplated by the Agreement or
any other Transaction Document, or any act, omission or event occurring in
connection therewith; and each of Seller and Servicer hereby waives, releases,

the Administrator (for the benefit of each Purchaser) in the Receivables and
related items (including the Pool Assets) have been taken and completed. The
Servicer and, to the extent that it ceases to be the Servicer, WESCO, also will
(and will cause each Originator to) maintain and implement administrative and
operating procedures (including an ability to recreate records evidencing
Receivables and related Contracts in the event of the destruction of the
originals thereof), and keep and maintain all documents, books, records,
computer tapes and disks and other information reasonably necessary or advisable
for the collection of all Receivables (including records adequate to permit the
daily identification of each Receivable and all Collections of and adjustments
to each existing Receivable).

        (c) PERFORMANCE AND COMPLIANCE WITH CONTRACTS AND CREDIT AND COLLECTION
POLICY. The Servicer and, to the extent that it ceases to be the Servicer,
WESCO, shall (and shall cause Originator to), at its expense, timely and fully
perform and comply with all material provisions, covenants and other promises
required to be observed by it under the Contracts related to the Receivables,
and timely and fully comply in all material respects with the Credit and
Collection Policy with regard to each Receivable and the related Contract.

        (d) EXTENSION OR AMENDMENT OF RECEIVABLES. Except as provided in the
Agreement, the Servicer and, to the extent that it ceases to be the Servicer,
WESCO, shall not extend (and shall not permit any Originator to extend), the
maturity or adjust the Outstanding Balance or otherwise modify the terms of any
Pool Receivable, or amend, modify or waive any term or condition of any related
Contract.

        (e) CHANGE IN BUSINESS OR CREDIT AND COLLECTION POLICY. The Servicer
and, to the extent that it ceases to be the Servicer, WESCO, shall not make (and
shall not permit any Originator to make) any change in the character of its
business or in any Credit and Collection Policy that would have a Material
Adverse Effect. The Servicer and, to the extent that it ceases to be the
Servicer, WESCO, shall not make (and shall not permit any Originator to make)
any other change in any Credit and Collection Policy without giving prior
written notice thereof to the Administrator and each Purchaser Agent.

        (f) AUDITS. The Servicer and, to the extent that it ceases to be the
Servicer, WESCO, shall (and shall cause each Originator to), from time to time
during regular business hours, but no more frequently than

annually unless (x) a Termination Event or Unmatured Termination Event has
occurred and is continuing or (y) in the opinion of the Administrator (with the
consent or at the direction of the Majority Purchasers) reasonable grounds for
insecurity exist with respect to the collectibility of a material portion of the
Pool Receivables or with respect to the Servicer's performance or ability to
perform in any material respect its obligations under the Agreement, as
reasonably requested in advance (unless a Termination Event or Unmatured
Termination Event exists) by the Administrator, permit the Administrator, or its
agents or representatives: (i) to examine and make copies of and abstracts from
all books, records and documents (including computer tapes and disks) in its
possession or under its control relating to Receivables and the Related
Security, including the related Contracts; and (ii) to visit its offices and
properties for the purpose of examining such materials described in CLAUSE (i)
above, and to discuss matters relating to Receivables and the Related Security
or its performance hereunder or under the Contracts with any of its officers,
employees, agents or contractors having knowledge of such matters.

        (g) CHANGE IN LOCK-BOX BANKS, LOCK-BOX ACCOUNTS AND PAYMENT INSTRUCTIONS
TO OBLIGORS. The Servicer and, to the extent that it ceases to be the Servicer,
WESCO, shall not (and shall not permit any Originator to) add or terminate any
bank as a Lock-Box Bank or any account as a Lock-Box Account from those listed
in Schedule II to the Agreement, or make any change in its instructions to
Obligors regarding payments to be made to the Servicer or any Lock-Box Account
(or related post office box), unless the Administrator and the Majority
Purchasers shall have consented thereto in writing and the Administrator shall
have received copies of all agreements and documents (including Lock-Box
Agreements) that it may request in connection therewith.

        (h) DEPOSITS TO LOCK-BOX ACCOUNTS. The Servicer shall: (i) instruct all
Obligors to make payments of all Receivables to one or more Lock-Box Accounts or
to post office boxes to which only Lock-Box Banks have access (and shall
instruct the Lock-Box Banks to cause all items and amounts relating to such
Receivables received in such post office boxes to be removed and deposited into
a Lock-Box Account on a daily basis); and (ii) deposit, or cause to be
deposited, any Collections received by it into Lock-Box Accounts not later than
one Business Day after receipt thereof. Except as otherwise agreed to in writing
by the Administrator and the Majority Purchasers, each Lock-Box Account shall at
all times be subject to a Lock-Box Agreement. The Servicer will not deposit or
otherwise credit, or cause or permit to be so deposited or credited, to any
Lock-Box Account cash or cash proceeds other than Collections.

        3. SEPARATE EXISTENCE. Each of the Seller and WESCO hereby acknowledges
that the Purchasers, the Purchaser Agents, the Administrator and the Liquidity
Providers are entering into the transactions contemplated by this Agreement and
the other Transaction Documents in reliance upon the Seller's identity as a
legal entity separate from WESCO and its Affiliates. Therefore, from and after
the date hereof, each of the Seller and WESCO shall take all steps specifically
required by the Agreement or reasonably required by the Administrator to
continue the Seller's identity as a separate legal entity and to make it
apparent to third Persons that the Seller is an entity with assets and
liabilities distinct from those of WESCO and any other Person, and is not a
division of WESCO, its Affiliates or any other Person. Without limiting the
generality of the foregoing and in addition to and consistent with the other
covenants set forth herein, each of the Seller and WESCO shall take such actions
as shall be required in order that:

               (a) The Seller will be a limited purpose corporation whose
        primary activities are restricted in its certificate of incorporation
        to: (i) purchasing or otherwise acquiring from the Originators, owning,
        holding, granting security interests or selling interests in Pool
        Assets, (ii) entering into agreements for the selling and servicing of
        the Receivables Pool, and (iii) conducting such other activities as it
        deems necessary or appropriate to carry out its primary activities;

               (b) The Seller shall not engage in any business or activity, or
        incur any indebtedness or liability, other than as expressly permitted
        by the Transaction Documents;

               (c) Not less than one member of the Seller's Board of Directors
        (the "Independent Director") shall be an individual who is not a direct,
        indirect or beneficial stockholder, officer, director, employee,
        affiliate, associate or supplier of WESCO or any of its Affiliates. The
        certificate of incorporation of the Seller shall provide that: (i) the
        Seller's Board of Directors shall not approve, or take any other action
        to cause the filing of, a voluntary bankruptcy petition with respect to
        the



                                      IV-9
<PAGE>   85


        Seller unless the Independent Director shall approve the taking of such
        action in writing before the taking of such action, and (ii) such
        provision cannot be amended without the prior written consent of the
        Independent Director;

               (d) The Independent Director shall not at any time serve as a
        trustee in bankruptcy for the Seller, WESCO or any Affiliate thereof;

               (e) Any employee, consultant or agent of the Seller will be
        compensated from the Seller's funds for services provided to the Seller.
        The Seller will not engage any agents other than its attorneys, auditors
        and other professionals, and a servicer and any other agent contemplated
        by the Transaction Documents for the Receivables Pool, which servicer
        will be fully compensated for its services by payment of the Servicing
        Fee, and a manager, which manager will be fully compensated from the
        Seller's funds;

               (f) The Seller will contract with the Servicer to perform for the
        Seller all operations required on a daily basis to service the
        Receivables Pool. The Seller will pay the Servicer the Servicing Fee
        pursuant to the Agreement. The Seller will not incur any material
        indirect or overhead expenses for items shared with WESCO (or any other
        Affiliate thereof) that are not reflected in the Servicing Fee. To the
        extent, if any, that the Seller (or any Affiliate thereof) shares items
        of expenses not reflected in the Servicing Fee or the manager's fee,
        such as legal, auditing and other professional services, such expenses
        will be allocated to the extent practical on the basis of actual use or
        the value of services rendered, and otherwise on a basis reasonably
        related to the actual use or the value of services rendered; it being
        understood that WESCO shall pay all expenses relating to the
        preparation, negotiation, execution and delivery of the Transaction
        Documents, including legal, agency and other fees;

               (g) The Seller's operating expenses will not be paid by WESCO or
        any other Affiliate thereof;

               (h) All of the Seller's business correspondence and other
        communications shall be conducted in the Seller's own name and on its
        own separate stationery;

               (i) The Seller's books and records will be maintained separately
        from those of WESCO and any other Affiliate thereof;

               (j) All financial statements of WESCO or any Affiliate thereof
        that are consolidated to include Seller will contain detailed notes
        clearly stating that: (i) a special purpose corporation exists as a
        Subsidiary of WESCO, and (ii) the Originators have sold receivables and
        other related assets to such special purpose Subsidiary that, in turn,
        has sold undivided interests therein to certain financial institutions
        and other entities;



                                     IV-10
<PAGE>   86


               (k) The Seller's assets will be maintained in a manner that
        facilitates their identification and segregation from those of WESCO or
        any Affiliate thereof;

               (l) The Seller will strictly observe corporate formalities in its
        dealings with WESCO or any Affiliate thereof, and funds or other assets
        of the Seller will not be commingled with those of WESCO or any
        Affiliate thereof except as permitted by the Agreement in connection
        with servicing the Pool Receivables. The Seller shall not maintain joint
        bank accounts or other depository accounts to which WESCO or any
        Affiliate thereof (other than WESCO in its capacity as the Servicer) has
        independent access. The Seller is not named, and has not entered into
        any agreement to be named, directly or indirectly, as a direct or
        contingent beneficiary or loss payee on any insurance policy with
        respect to any loss relating to the property of WESCO or any Subsidiary
        or other Affiliate of WESCO. The Seller will pay to the appropriate
        Affiliate the marginal increase or, in the absence of such increase, the
        market amount of its portion of the premium payable with respect to any
        insurance policy that covers the Seller and such Affiliate; and

               (m) The Seller will maintain arm's-length relationships with
        WESCO (and any Affiliate thereof). Any Person that renders or otherwise
        furnishes services to the Seller will be compensated by the Seller at
        market rates for such services it renders or otherwise furnishes to the
        Seller. Neither the Seller nor WESCO will be or will hold itself out to
        be responsible for the debts of the other or the decisions or actions
        respecting the daily business and affairs of the other. The Seller and
        WESCO will immediately correct any known misrepresentation with respect
        to the foregoing, and they will not operate or purport to operate as an
        integrated single economic unit with respect to each other or in their
        dealing with any other entity.

               (n) WESCO shall not pay the salaries of Seller's employees, if
any.
