                    PC SERVICE SOURCE, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)
                                   (UNAUDITED)

(1)      BASIS OF PRESENTATION

         These unaudited condensed consolidated financial statements of PC
         Service Source, Inc. and its majority owned subsidiaries (collectively
         the "Company"), for the three and six months ended June 30, 1998 and
         1997, have been prepared in accordance with generally accepted
         accounting principles for interim financial reporting. Accordingly,
         they do not include all of the information and footnotes required by
         generally accepted accounting principles for complete financial
         statements and should be read in conjunction with the audited
         consolidated financial statements and notes thereto included in the
         Company's Form 10-K for the year ended December 31, 1997. All
         significant intercompany balances and transactions have been eliminated
         in consolidation. In the opinion of management, all adjustments
         (consisting only of normal recurring adjustments) considered necessary
         for a fair presentation of the interim financial information have been
         included. The results of operations for any interim period are not
         necessarily indicative of the results of operations for a full year.


(2)      EARNINGS (LOSS) PER SHARE

         The Company adopted Statement of Financial Accounting Standards No.
         128 (SFAS 128), Earnings per Share, in the fourth quarter of 1997,
         which required companies to present basic earnings per share and
         diluted earnings per share. Basic earnings per share is computed by
         dividing income available to common stockholders by the weighted
         average number of common shares outstanding during the period. Diluted
         earnings per share reflects the potential dilution that could occur if
         securities or other contracts to issue common stock were exercised or
         converted into common stock. The Company has restated its earnings per
         share calculations for the three and six months ended June 30, 1997 to
         reflect the adoption of SFAS 128.

         The following table sets forth the computation of basic and diluted
         earnings per share.

         The weighted average common shares outstanding-diluted computation for
         the three and six months ended June 30, 1998, respectively excluded 107
         and 119 employee stock options and other common stock equivalents
         because this impact would be anti-dilutive.

(3)      COMPREHENSIVE INCOME

         The Company adopted Statement of Financial Accounting Standards No. 130
         (SFAS 130), Reporting Comprehensive Income, in the first quarter of
         1998, which requires companies to disclose comprehensive income
         separately from net income from operations. Comprehensive income is
         defined as the change in equity during a period from transactions and
         other events and circumstances from non-ownership sources. It includes
         all changes in equity during a period, except those resulting from
         investments by owners and distributions to owners. Comprehensive income
         (loss) was ($2,241) and $271 for the three months and ($2,073) and $718
         for the six months ended June 30, 1998 and 1997.


(4)      SUPPLEMENTAL CASH FLOW INFORMATION

         Net cash flow from operating activities reflects cash payments for
         interest and income taxes as follows:

</TABLE>


THREE MONTHS ENDED JUNE 30, 1998 COMPARED TO THREE MONTHS ENDED JUNE 30, 1997

Net revenues were $38.3 million for the second quarter of 1998,
representing an increase of $6.6 million or a 21% increase over the second
quarter of 1997. Revenues are comprised of general parts distribution
operations, service provider alliances, original equipment manufacturers
outsourcing arrangements and remanufacturing. The Company saw a shift in revenue
mix during the second quarter from general parts distribution to service
provider alliances, mainly due to increased service logistics outsourcing
agreements, which contributed primarily to the increase in revenues.

Gross margin as a percentage of net revenues decreased in the second quarter of
1998 to 29.6% from 29.9% in the same period in 1997. The Company's gross margin
on each computer part in inventory varies; therefore, any change in the mix of
parts sold will impact the gross margin from quarter to quarter. During the
second quarter of 1998, gross margin as a percentage of revenue declined due
primarily to a higher mix of lower margin service logistics outsourcing
business. However, a pricing strategy designed to recover more of the costs
incurred in acquiring, stocking, and selling computer parts helped offset this
gross margin decrease.




                                      -6-

Selling, general and administrative expenses ("SG&A") as a percentage of net
revenues increased to 35.1% in the second quarter of 1998 compared to 25.6%
incurred in the second quarter of 1997. The increase in SG&A as a percentage of
revenue was principally due to three unusual factors which contributed equally
to the increase. The first factor was an increase in employee expenses resulting
from new employees hired and trained to handle the Dell Computer laptop repair
contract, overtime and temporary works to assist in the conversion to the
Company's automated warehouse management system, and severance expenses for
former employees. The second factor was a non-recurring charge related to the
termination of an unprofitable warranty processing program with an OEM customer
with whom the Company has other successful programs pending. The third factor
was an increase in freight expense resulting from deficiencies in freight
monitoring, control, and billing processes. These deficiencies were discovered
in connection with the warehouse management system conversion, and management
believes that proper freight billing controls are now in place. While these
three factors principally account for the increase in SG&A expense, that expense
was also adversely impacted, but to a lesser extent by freight concessions
to customers in connection with slow shipping during the warehouse management
system conversion.

Depreciation and amortization increased as a percentage of net revenues to 3.0%
in the second quarter of 1998 compared to 2.5% in the same period of 1997. The
increase is due to a higher asset base in 1998 resulting from the significant
capital expenditures made by the Company during 1997.

Interest expense (net) as a percentage of net revenues increased to .8% during
the second quarter of 1998 from .4% during the same period of 1997 due to a
higher average outstanding balance on the Company's revolving line of credit
during the second quarter of 1998.

SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997

Net revenues were $76.8 million for the first six months of 1998, representing
an increase of $12.7 million or a 20% increase over the first six months of
1997. The increase was primarily attributed to the increase in service logistics
outsourcing agreements with the Company's service provider alliances.

Gross margin as a percentage of net revenues increased in the first half of 1998
to 29.3% from 28.8% in the same period in 1997. The Company's gross margin on
each computer part in its inventory is different; therefore, any change in the
mix of parts sold will impact the Company's gross margin from period to period.
During the first half of 1998, gross margin percentage improved because of the
adoption of a pricing strategy designed to recover more of the costs incurred in
acquiring, stocking and selling computer parts. During the same period in 1997,
the Company had lowered the average selling price on certain products to
aggressively compete for additional revenue.

SG&A as a percentage of net revenues increased to 30.0% in the first half of
1998 compared to 24.2% incurred in the first half of 1997 primarily for the same
reasons as explained in the three months ended June 30, 1998 compared to the
three months ended for June 30, 1997 analysis discussed above.

                    PC SERVICE SOURCE, INC. AND SUBSIDIARIES

Depreciation and amortization increased as a percentage of net revenues to 2.8%
in the first six months of 1998 compared to 2.4% in the same period of 1997. The
increase was due to a higher asset base in 1998 resulting from the significant
capital expenditures made by the Company during 1997.

Interest expense (net) as a percentage of net revenues increased to .8% during
the first half of 1998 from .4% during the same period of 1997 due to a higher
average outstanding balance on the Company's revolving line of credit during the
first half of 1998.

LIQUIDITY AND CAPITAL RESOURCES

The Company currently maintains a $20 million revolving bank credit facility
which matures in June 1999. During the second quarter of 1998, the Company
exceeded an agreed upon ratio which triggered a total borrowing base
availability calculation ("asset-based calculation"), which is based upon
defined percentages of eligible accounts receivable and inventory. As a result,
the amount currently available under the Company's credit facility is limited to
the lesser of $20.0 million or calculated availability based on the asset-based
calculation. The Company's available credit facility at June 30, 1998 was $20.0
million. 

The Company was not in compliance with certain financial performance covenants
at June 30, 1998. The Company has received a waiver from its lenders with
respect to the covenants and intends to renegotiate the facility to revise
certain covenants. The Company also intends to extend the maturity date of the
facility. The inability of the Company to extend the maturity date of the
facility or to obtain similar alternate financing sources could have a material
adverse impact on the liquidity and capital resources of the Company.

The Company has historically been a net user of cash from operating activities
and has financed its capital expenditure requirements from revolving credit,
lease financing agreements and equity financing. Cash used in operating
activities during the first six months of 1998 was $1.0 million as compared with
cash used in operating activities of $1.2 million for the first six months of
1997.

Capital expenditures, including capital assets acquired through leasing
arrangements, totaled $3.0 million for the first six months of 1998 compared
with $3.4 million in 1997. Expenditures in the 1998 period were primarily
related to the Company's new warehouse management system.

YEAR 2000 COMPLIANCE

In January 1997, the Company developed a plan to deal with the Year 2000 problem
and began converting its computer systems to be Year 2000 compliant. The plan
provides for the conversion efforts to be completed by the end of 1998. The Year
2000 problem is a result of computer programs being written using two digits
rather than four to define the applicable year. The total cost of the project is
estimated to be $200,000 and is being funded through operating cash flows. The
Company is expensing all costs associated with these systems changes as the
costs are incurred. As of June 30, 1998, approximately $60,000 has been 
expensed.

To the extent possible, the Company will develop and implement contingency plans
designed to allow continued operations in the event of failure of the Company's
or third parties' systems to be Year 2000 compliant. For example, the Company
plans to have dedicated staff available at crucial dates to remedy unforeseen
problems.

CAUTION REGARDING FORWARD-LOOKING STATEMENTS

The Company occasionally makes forward-looking statements concerning its plans,
goals, product and service offerings, and anticipated financial performance.
These forward-looking statements may generally be identified by introductions
such as "outlook" for an upcoming period of time, or words and phrases such as
"should", "expect", "hope", "plans", "projected", "believes", "forward-looking"
(or variants of those words and phrases) or similar language indicating the
expression of an opinion or view concerning the future.

These forward-looking statements are subject to risks and uncertainties based on
a number of factors and actual results or events may differ materially from
those anticipated by such forward-looking statements. These factors include, but
are not limited to: the growth rate of the Company's revenue and market share;
the consummation of new and the non-termination of existing OEM outsourcing
arrangements and service provider alliances; the Company's ability to
effectively manage its business functions while growing the Company's business
in a rapidly changing environment; the ability of the Company to adapt and
expand its services in such an environment; the effective and efficient
purchasing of parts and processing of sales orders; and the quality of the
Company's plans and strategies, and the ability of the Company to execute such
plans and strategies.

In addition, forward-looking statements concerning the Company's expected
revenue or earnings levels are subject to many additional uncertainties
applicable to competitors generally and to general economic conditions over
which the Company has no control. The Company generally does not plan to
publicly update prior forward-looking statements for unanticipated events or
otherwise and, accordingly, prior forward-looking statements should not be
considered to be "fresh" simply because the Company has not made additional
comments on those forward-looking statements.

B.       REPORTS ON FORM 8-K

         A report on Form 8-K was filed by the Company on June 15, 1998,
         reporting that during May and June 1998, the Company requested several
         independent accounting firms, including its existing independent
         auditor, to submit a proposal for providing audit and tax services to
         the Company. KPMG Peat Marwick LLP, the Company's independent auditor
         at that time, advised the Company that it would not be participating in
         the request for proposal and resigned as the Company's independent
         auditor. At a meeting held on June 17, 1998, the Audit Committee of the
         Board of Directors of the Company approved the engagement of Ernst &
         Young LLP, as its independent auditor for the fiscal year ending
         December 31, 1998, to replace the firm of KPMG Peat Marwick LLP.
