                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


(1)  BASIS OF PRESENTATION

     The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. These consolidated financial statements should be read in
conjunction with the audited financial statements and notes thereto included in
the ProSource Inc. (the "Company") Annual Report on Form 10-K/A for the fiscal
year ending December 27, 1997.

     The Company operates on a 52- to 53-week accounting year ending on the last
Saturday of each calendar year. Operating results for the thirteen weeks ended
March 28, 1998 are not necessarily indicative of the results that may be
expected for the fiscal year ending December 26, 1998 due, in part, to seasonal
fluctuations in the Company's business, the potential addition or loss of
customers, and changes in economic conditions.

     Certain amounts previously presented in the financial statements of prior
periods have been reclassified to conform to the current period's presentation.

(2) EXTRAORDINARY CHARGE

     In March, 1997, the Company entered into two five-year loan agreements
aggregating $225 million with a group of financial institutions to replace its
previous credit facility. In connection with this early retirement of long-term
debt, the Company recorded a pre-tax extraordinary charge of $10.3 million ($6.3
million net of taxes) in the first quarter of fiscal 1997. This charge reflected
the write-off of deferred financing costs of $6.3 million, prepayment penalties
of $2.7 million and $1.3 million in costs associated with the termination of
interest-rate protection agreements.

(3) IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

      In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 130, "Reporting Comprehensive Income," which establishes standards
for reporting and display of comprehensive income and its components. The
Company adopted this statement in the first quarter of fiscal 1998 and has
reflected the components of its comprehensive loss in the accompanying
consolidated statements of comprehensive loss.

      In June 1997, the FASB also issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information." This statement establishes
standards for reporting information about a company's operating segments and
related disclosures about its products, services, geographic areas of operations
and major customers. The Company plans to adopt this statement in the fourth
quarter of fiscal 1998 and does not believe the adoption will materially impact
the Company's results of operations, cash flows or financial position.

(4) CONTINGENCIES

      The Company and its subsidiaries are parties to various legal actions
arising in the ordinary course of business. Management believes that the outcome
of such cases will not have a material adverse effect on the consolidated
results of operations or the financial position of the Company.

(5)   NET LOSS PER COMMON SHARE

      For all periods presented in the accompanying consolidated statements of
operations, there are no reconciling items to the numerator of the basic and
diluted net loss per common share computations. For the period ended March 28,
1998, all stock options and other potential common shares were excluded from the
calculation of diluted loss per share, since they would produce anti-dilutive
results. As a result, there are no reconciling items to the denominator of the
basic and diluted loss per share computations for the period ended March 28,
1998.

      The following table sets forth the reconciliation of the denominator of
the basic and diluted net loss per common share computation for the period ended
March 29, 1997:

(6)   MERGER

      On January 29, 1998, the Company signed a definitive merger agreement with
AmeriServe Food Distribution, Inc. ("AmeriServe"). Under the terms of the
agreement, AmeriServe has agreed to pay $15.00 in cash for each outstanding
share of the Company's common stock. In addition, under the agreement, all
outstanding options will be accelerated and option holders will receive $15.00
less the applicable exercise price for each share issuable upon exercise of the
options. AmeriServe has indicated that it intends to refinance all of the
Company's outstanding debt.

      The merger is subject to regulatory approvals and other customary
conditions to closing. The Federal Trade Commission has informed the Company
that the waiting period under the Hart Scott Rodino Antitrust Improvements Act
of 1976 has expired. Onex Corporation and certain of its affiliates, which own
approximately 61% of the Company's outstanding stock, representing approximately
85% of the voting power, have committed to vote in favor of the merger, which
will assure the necessary shareholder approval. The special shareholder meeting
to vote on the merger is scheduled for May 20, 1998 and the merger is expected
to close by the end of May 1998.

THIRTEEN WEEKS ENDED MARCH 28, 1998 COMPARED TO THIRTEEN WEEKS ENDED MARCH 29, 
1997

     Net sales declined 2.7% to 989.8 million in 1998 from $1,017.1 million in
1997. The decrease is primarily attributed to the Company's decision to
terminate its distribution contract with ARCOP, the purchasing cooperative for
Arby's restaurants, effective April 1, 1997. In 1997, sales to Arby's
restaurants (primarily franchisee-owned) accounted for approximately 9.7% of
the Company's sales. The Company has been able to offset the full impact of
this termination by increasing its sales to its current customer base, through
increased sales to existing restaurants and increasing the number of
restaurants served, and by adding new customers, such as Lone Star Steakhouse
& Saloon, Inc. (owner/franchisor of Lone Star Steakhouse Restaurants), which
the Company began servicing on March 18, 1998.

     The Company's gross profit decreased by 3.0% to $78.2 million in 1998 from
$80.7 million in 1997. The gross profit percentage remained constant at 7.9%.
The reduction in gross profit dollars is due to the reduced sales caused by the
Arby's contract termination, discussed previously.

     Operating expenses decreased slightly by 0.2% to $78.0 million in 1998 from
$78.1 million in 1997. However, as a percentage of net sales, operating expenses
increased to 7.9% in 1998 from 7.7% in 1997 due primarily to the impact that
certain fixed costs have on a lower sales volume.

                      QUARTERLY PERIOD ENDED MARCH 28, 1998


     The Company reported income from operations totaling $0.2 million in 1998
compared to $2.6 million in 1997. This decrease is due to a combination of lower
gross profit dollars earned on a lower sales volume and certain fixed operating
expenses.

     Net interest expense increased by $1.3 million to $3.4 million in 1998 from
$2.1 million in 1997. This increase is due primarily to increased borrowings
from the Company's credit facilities required to finance the Company's
operations, including capital expenditures. See "Liquidity and Capital
Resources".

     The Company recognized an income tax benefit in 1998 of $1.5 million
compared to a provision for income taxes of $0.2 million in 1997. The effective
income tax rates for 1998 and 1997 were 48.1% and 44.3%, respectively. The
higher rate for 1998 is based on the projected pre-tax results for fiscal 1998
which are lower (on an absolute dollar basis) than the pre-tax results
originally projected for fiscal 1997. Since permanent differences have remained
approximately the same, this causes the effective tax rate to increase.

     In 1997, the Company recognized an extraordinary charge of $10.3 million
($6.3 million net of taxes) associated with the early retirement of its previous
credit facility. This charge includes the write-off of deferred financing costs
($6.3 million), prepayment penalties ($2.7 million) and costs associated with
the termination of interest-rate protection agreements ($1.3 million).

     Overall, the Company reported a loss in 1998 of $1.7 million, $0.18 per
share, compared to a loss of $6.0 million, $0.64 per share, in 1997. The
improvement in 1998 is due to the non-recurring extraordinary charge recognized
in 1997, discussed previously.

     Restaurants owned or franchised by Burger King Corporation collectively
accounted for 44.9% and 40.2% of the Company's sales in 1998 and 1997,
respectively. In addition, sales to Darden Restaurants, Inc. (owner of Red
Lobster and Olive Garden restaurants) accounted for 23.2% and 22.8% of the
Company's sales in 1998 and 1997, respectively. No other customer or restaurant
concept accounted for more than 10% of the Company's sales in 1998 and 1997.

LIQUIDITY AND CAPITAL RESOURCES

     The Company meets its liquidity needs through cash provided by operations,
normal vendor trade-credit terms, operating leases and borrowings under its
credit facilities. The Company used net cash of $2.5 million for its operating
activities in 1998. The Company generated net cash from operating activities of
$2.7 million in 1997. Cash flow in 1998 was negatively impacted primarily by a
reduction in accounts payable.

     Cash used for capital expenditures was $9.0 million in 1998, primarily for
distribution facilities and equipment ($5.7 million) and computer system
upgrades ($3.3 million). In 1997, the Company used $6.6 million for capital
expenditures, primarily for distribution facilities and equipment ($4.2 million)
and computer system upgrades ($1.8 million). The Company anticipates capital
expenditures of approximately $19.0 million for fiscal year 1998; however, there
can be no assurance that capital expenditures will not exceed such amount.

     The Company's credit facilities consist of two five-year loan agreements
aggregating $225 million with a group of financial institutions, a $150 million
accounts receivable securitization facility and a $75 


                                       11

million revolving-credit facility. The facilities bear interest based on either
the prime rate or LIBOR plus an additional spread based on certain financial
ratios and mature on March 14, 2002. The Company is

required to comply with various covenants, and borrowings are subject to
calculations based on accounts receivable and inventory. These agreements are
secured by liens on substantially all of the Company's assets and contain
various restrictions on, among other things, the Company's ability to pay
dividends and dispose of assets. ProSource Receivables Corporation ("PRC"), a
subsidiary of ProSource Services Corporation, the Company's principal operating
subsidiary ("PSC"), is the legal borrower for the accounts receivable
securitization facility. Pursuant to the terms of the accounts receivable
securitization facility PSC sells, on an ongoing basis and without recourse, an
undivided interest in a designated pool of trade accounts receivable to PRC. In
order to maintain the designated balance in the pool of accounts receivable
sold, PSC is obligated to sell undivided interests in new receivables as
existing receivables are collected. PSC has retained substantially the same
credit risk as if the receivables had not been sold. PSC, as agent for PRC,
retains collection and administrative responsibilities on the receivables sold
to PRC. The creditors for this facility have security interests in PRC's assets
(consisting primarily of accounts receivable purchased from PSC) and are
entitled to be satisfied by such assets prior to equity holders.

     The Company borrowed a net of $11.1 million in 1998 under its credit
facilities to fund its operating and investing activities. In 1997, the Company
borrowed a net of $16.4 million under its credit facilities to fund its
investing and other financing activities and to increase its cash and cash
equivalents. The Company paid approximately $4.2 million in 1997 for fees
associated with the early extinguishment of its previous credit facility and for
loan fees on its new credit facilities, which closed in March 1997.
Approximately $0.5 million was paid in 1997 to acquire and retire treasury
stock.

     The Company believes that the combination of cash flow generated from
operations and borrowings under the existing credit facilities are sufficient to
satisfy its anticipated capital expenditures and working capital needs for at
least twelve months. Management may determine that it is necessary or desirable
to obtain financing for growth through additional bank borrowings or the
issuance of new debt or equity securities.

IMPACT OF FLUCTUATION IN PRODUCT COST AND INFLATION

     A significant portion of the restaurants served by the Company purchase
products from the Company based on product cost plus a negotiated fixed dollar
amount per unit of measure. As a result, the Company's gross margin percentage
may be positively or negatively impacted as the product cost per unit of measure
decreases or increases, respectively. Moreover, inflation in operating expenses
without corresponding productivity improvements can have a negative effect on
the Company's operating results as operating expenses increase while gross
profit remains constant.

INFORMATION SYSTEMS AND THE IMPACT OF THE YEAR 2000

     Since 1995, the Company has been actively engaged in a program to replace
and/or upgrade its significant transaction processing systems. This effort was
initiated to effect the integration of acquired businesses. As a result of this
program, the Company believes that it will be Year 2000 compliant on all of its
significant applications by the end of 1998. The Company has engaged a firm to
conduct an outside review to ensure the Company's entire enterprise compliance
readiness. Until this review is complete, however, there can be no assurance
that significant efforts will 


                                       12
<PAGE>   13
not be required to ensure Year 2000 compliance, including with respect to its
customer and vendor relationships. For the period ended March 28, 1998, the
Company expensed approximately $0.1 million associated with Year 2000
remediation efforts.

PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

         The Company and its subsidiaries are parties to various legal actions
         arising in the ordinary course of business. Management believes that
         the outcome of such cases will not have a material adverse effect on
         the consolidated results of operations or the financial position of the
         Company.

ITEM 5.  OTHER INFORMATION

         Forward Looking Statements

         This quarterly report contains certain forward-looking statements
         within the meaning of Section 21E of the Securities Exchange Act of
         1934 that involve risks and uncertainties. Such forward-looking
         statements include, among other things, statements regarding sources of
         growth, the potential impact of pending litigation and Year 2000
         compliance and anticipated capital expenditures and working capital
         needs. Actual outcomes may be affected by unexpected developments
         impacting the Company and the restaurant industry such as adverse
         situations affecting the largest chains serviced by the Company or a
         decision by a major customer to revoke its approval of the Company as a
         distributor, and other developments such as unforeseen costs and
         expenses or changes in economic conditions, including inflation. Also,
         the Company is in a highly competitive business and is in the process
         of implementing a strategic plan intended to expand its business and
         improve its cost structure. There can be no assurance that in its
         highly competitive business environment, the Company will achieve the
         planned growth and cost savings.
