                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
ProSource, Inc.:
 
     We have audited the accompanying consolidated balance sheets of ProSource,
Inc. and subsidiaries as of December 28, 1996 and December 27, 1997, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the years in the three-year period ended December 27, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of ProSource,
Inc. and subsidiaries as of December 28, 1996 and December 27, 1997, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 27, 1997, in conformity with generally accepted
accounting principles.
 
     As discussed in Note 13 to the consolidated financial statements, the
Company changed its method of capitalization of business process reengineering
activities in the fourth quarter of 1997.

     YEARS ENDED DECEMBER 30, 1995, DECEMBER 28, 1996 AND DECEMBER 27, 1997
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) The Business
 
     ProSource, Inc. (the "Company") provides foodservice distribution services
to chain restaurants in North America and provides purchasing and logistics
services to the foodservice market. The Company's 3,400 associates serve
approximately 12,700 restaurants, consisting primarily of Burger King, Red
Lobster, Long John Silver's, Olive Garden, TGIFriday's, Chick-fil-A, Chili's,
Sonic, TCBY and Wendy's restaurant concepts, from 34 distribution centers and
its Corporate Support Center in Coral Gables, Florida.
 
     The Company operates through ProSource Services Corporation ("PSC"), a
wholly owned subsidiary, and PSC's four main wholly-owned operating
subsidiaries, ProSource Distribution Services Limited ("ProSource Canada"),
BroMar Services, Inc. ("BroMar"), ProSource Receivables Corporation ("PRC"), and
PSD Transportation Services, Inc. ("PSD"). PSC commenced operations in July
1992. PRC and PSD commenced operations during fiscal 1997. The consolidated
financial statements include the results of the operations of PSC, PRC and PSD
from their inception and the results of operations of ProSource Canada and
BroMar, which were formed or acquired by the Company in connection with the
acquisition of the National Accounts Division ("NAD") of The Martin-Brower
Company ("Martin-Brower"), since the date of acquisition. The Company is a
subsidiary of Onex Corporation (collectively with its affiliates, "Onex"), a
company traded on the Toronto and Montreal stock exchanges.
 
     The Company operates on a 52- to 53-week accounting year, ending on the
last Saturday of each calendar year.
 
  (b) Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. Operations of the companies and businesses acquired have
been included in the accompanying consolidated financial statements from their
respective dates of acquisition. All significant intercompany accounts and
transactions have been eliminated in consolidation.
 
  (c) Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  (d) Cash and Cash Equivalents
 
     Cash on hand and in banks and short-term securities with maturities of
three months or less when purchased are considered cash and cash equivalents.
 
  (e) Inventories
 
     Inventories, consisting primarily of food items, are stated at the lower of
cost or net realizable value. Cost is determined using the weighted-average-cost
method and the first-in, first-out method. Cost of inventory using the
weighted-average-cost method represents 32%, 32% and 34% of inventories in 1995,
1996, and 1997, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  (f) Property and Equipment
 
     Property and equipment are stated at cost, less accumulated depreciation
and amortization. Depreciation is computed using the straight-line method over
the estimated useful lives of the related assets. Amortization of leasehold
improvements is computed using the straight-line method over the shorter of the
lease term or estimated useful lives of the related assets.
 
     Costs of normal maintenance and repairs are charged to expense when
incurred. Replacements or betterments of properties are capitalized. When assets
are retired or otherwise disposed of, their cost and the applicable accumulated
depreciation and amortization are removed from the accounts, and the resulting
gain or loss is reflected in the consolidated statements of operations.
 
  (g) Intangible Assets
 
     Intangible assets are amortized using the straight-line method over the
following periods:
 
<TABLE>
<S>                                                           <C>
Goodwill....................................................  40 years
Noncompete agreements.......................................   5 years
Customer lists..............................................  12 years
</TABLE>
 
     Goodwill represents the excess of cost over fair value of net assets
acquired. The Company periodically evaluates the recoverability of recorded
costs for goodwill based upon estimations of future undiscounted related
operating income from the acquired companies. Should the Company determine it
probable that future estimated undiscounted related operating income from any of
its acquired companies will be less than the carrying amount of the associated
goodwill, an impairment of goodwill would be recognized, and goodwill would be
reduced to the amount estimated to be recoverable. The Company believes that no
material impairment existed at December 28, 1996 and December 27, 1997.
 
  (h) Deferred Debt-Issuance Costs
 
     Included in other assets are deferred debt-issuance costs which are
amortized over the term of the related debt.
 
  (i) Self-Insurance
 
     The Company self-insures up to certain retention limits under its workers'
compensation (except for a period during 1996-1997), auto liability and medical
and dental insurance programs. Costs in excess of retention limits are insured
under various contracts with insurance carriers. Estimated costs for claims for
which the Company is responsible are determined based on historical claims
experience, adjusted for current trends. The liability related to workers'
compensation is discounted to net present value using a risk-free treasury rate
for maturities that match the expected settlement periods. At December 28, 1996
and December 27, 1997, the estimated accrued liabilities related to workers'
compensation were approximately $4.4 million and $3.3 million, respectively, net
of a discount of approximately $1.6 million and $1.0 million, respectively.
 
  (j) Net Loss Per Common Share
 
     In February 1997, Statement of Financial Accounting Standards ("SFAS") No.
128, "Earnings per Share" was issued. SFAS No. 128 replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings per
share. Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to
 
                                     F-7
<PAGE>   10
                                PROSOURCE, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the previously reported fully diluted earnings per share. All earnings per share
amounts for all periods have been presented, and where appropriate, restated to
conform with the requirements of SFAS No. 128.
 
     Shares and options issued within one year prior to the filing of the
Registration Statement relating to the initial public offering (see note 10)
have been treated as outstanding for all periods presented, even where the
impact of the incremental shares is antidilutive.
 
  (k) Income Taxes
 
     The Company and its wholly-owned domestic subsidiaries file consolidated
federal and state tax returns in the United States. Separate foreign tax returns
are filed for the Company's Canadian subsidiary. The Company follows the asset
and liability method of accounting for income taxes prescribed by SFAS No. 109,
"Accounting for Income Taxes." Under the asset and liability method, deferred
income taxes are recognized for the tax consequences of "temporary differences"
by applying enacted statutory tax rates applicable to future years to
differences between the financial statement carrying amounts and the tax basis
of existing assets and liabilities. The effect on deferred taxes of a change in
tax rates is recognized in income in the year that includes the enactment date.
 
  (l) Translation of Foreign Currency
 
     The accounts of ProSource Canada are translated into U.S. dollars in
accordance with SFAS No. 52, "Foreign Currency Translation." Consequently, all
balance sheet accounts are translated at the current exchange rate. Income and
expense accounts are translated at the average exchange rates in effect during
the year. Adjustments resulting from the translation are included in accumulated
foreign-currency translation adjustments as a component of stockholders' equity.
 
  (m) 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. 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. Both statements will be adopted by the Company in 1998.
Management believes the adoption of these statements will not materially impact
the Company's results of operations, cash flows or financial position.
 
  (n) Fair Value of Financial Instruments
 
     The carrying amounts reported in the consolidated balance sheets for cash
and cash equivalents, accounts receivable, accounts payable and accrued
liabilities approximate fair value because of their short-term maturities. The
carrying amounts reported for long-term debt approximate fair value because they
are variable-rate instruments that reprice monthly.
 
  (o) Reclassifications
 
     Certain amounts previously presented in the financial statements of prior
years have been reclassified to conform to the current year presentation.
 
2. BUSINESS COMBINATIONS
 
     On March 31, 1995, the Company completed the acquisition of substantially
all of the assets and the assumption of certain liabilities of NAD from
Martin-Brower. The total cost of the acquisition of $170 million


                                     F-8
<PAGE>   11
                                PROSOURCE, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
was funded through a borrowing of $116 million under the Company's previous
revolving credit facility, a $9 million note payable to Martin-Brower (net of a
discount to reflect a constant interest rate), $18.5 million in notes payable to
Onex, and the issuance of 2,650,000 shares of the Company's Class B common
stock, valued at approximately $26.5 million. The acquisition has been accounted
for under the purchase method of accounting. The accompanying consolidated
financial statements include the assets acquired of approximately $232 million,
consisting primarily of accounts receivable and inventories, and liabilities
assumed of approximately $87 million, consisting primarily of trade accounts
payable, based on their estimated fair values at the acquisition date. As a
result of this transaction, the Company recorded goodwill of approximately $25
million. In addition, the Company incurred an extraordinary charge relating to
the write-off of approximately $0.8 million of unamortized deferred-debt
issuance costs on debt repaid at the acquisition date.
 
     On March 30, 1996, the Company revised its estimates of certain costs
related to the acquisition by $12 million. The effect of the revision increased
acquisition-related liabilities by $12 million, deferred tax assets by
approximately $4.4 million and goodwill by approximately $7.6 million.
 
3. RESTRUCTURING, TERMINATION CHARGES AND IMPAIRMENT OF LONG-LIVED ASSETS
 
     In conjunction with the NAD acquisition, the Company incurred restructuring
costs of approximately $0.7 million in 1995 primarily relating to costs incurred
to consolidate and integrate certain functions and operations. In 1996, as a
result of a study to analyze, among other things, ways to integrate the NAD
operations, improve customer service, reduce operating costs and increase
existing warehouse capacity, the Company adopted a plan, which was approved by
its Board of Directors, to consolidate and integrate its corporate and network
operations, including the closing of 19 distribution facilities under lease
agreements and 11 owned distribution facilities. As a result, in the first
quarter of 1996, the Company accrued restructuring charges of $10.9 million,
primarily related to the termination of the existing facility leases and
employee related costs. The Company began the integration of some of these
facilities, including communications to its employees and its customers in 1996.
During 1997, the Company undertook a thorough evaluation of each specific
facility's return on investment and alternative uses. As a result, the Company
now intends to close 10 distribution facilities currently leased and 9
distribution facilities currently owned. The Company expects to complete the
plan in stages through the year 2002. During 1996 and 1997, the Company paid in
the aggregate $2.8 million and $1.7 million, respectively, in costs primarily
related to facility leases and relocation costs. In addition, during 1997 the
Company reclassified $3.4 million to acquisition related liabilities. As of
December 27, 1997, the Company had approximately $3.0 million of accrued unpaid
restructuring charges. Management believes that the remaining accrued
restructuring charges are adequate to complete its plans.
 
     The significant change brought about by the plan to integrate and
consolidate the existing distribution network impaired the value of long-lived
assets to be held and used until the plan is completed. As a result, in
conjunction with the recording of the restructuring reserves in the first
quarter of 1996, the Company recognized a loss on impairment in value of
long-lived assets. The loss consisted of $7.3 million of land and owned
buildings, $4.3 million of furniture and equipment and leasehold improvements
management plans to hold and use through the completion of the plan, and $4.1
million of capitalized software costs which do not meet the long-term
information technology strategy of the Company. The Company measured the amount
of the loss by comparing fair value of the land and the owned buildings
(determined by independent appraisals and updated with current comparisons to
similar assets) to capitalized cost. The carrying value of furniture and
equipment and capitalized software costs was written down to net realizable
value since it is being replaced.
 
     The Company discontinued its distribution services to Arby's restaurants
effective April 1, 1997. In connection therewith, as of December 28, 1996, the
Company accrued approximately $10.6 million of costs associated with the
termination of this agreement. During 1997, the Company paid and charged in the
aggregate $9.1 million in costs primarily related to lease costs in connection
with idle equipment and

warehouse space and costs associated with rerouting the Company's transportation
fleet required as a result of the loss of the Arby's business. In addition, the
Company reclassified approximately $1.2 million to the allowance for doubtful
accounts receivable to reserve against outstanding Arby's accounts receivable.
As of December 27, 1997, the Company had approximately $0.3 million of accrued
unpaid termination charges which management believes will be paid during 1998.

  (a) Existing Credit Facilities
 
     In March, 1997, the Company entered into two five-year loan agreements
aggregating $225 million (the "Existing Credit Facilities") 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.
 
     The Existing Credit 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 effective rate at December 27, 1997 was 7.34%. The
Company is required to comply with various covenants in connection with the
Existing Credit Facilities and borrowings are subject to calculations based on
accounts receivable and inventory. The revolving credit facility is secured by
liens on substantially all of the Company's assets and contains various
restrictions on, among other things, the Company's ability to pay dividends and
dispose of assets. Additionally, in the event of a change in control, the
outstanding principal amount of these facilities shall become due and payable.
PRC 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 pays a quarterly variable
commitment fee, as defined in the agreements, based on the unused portion of the
facilities which fee averaged 0.33% of such unused portion during 1997. At
December 27, 1997, the Company had approximately $35 million available under the
Existing Credit Facilities.
 
  (b) Previous Credit Facility
 
     On March 31, 1995, in conjunction with the acquisition of NAD, the Company
entered into a $240 million Loan and Security Agreement (the "Previous Credit
Facility") with a group of banks that was retired and repaid before its maturity
on March 14, 1997. The Previous Credit Facility provided for a revolving-credit
facility of up to $210 million and term loans aggregating $30 million. The
interest rate on the Previous Credit Facility was reset every month to reflect
current market rates. The effective rate during fiscal 1995 and 1996 was 8.7
percent. This rate reflected the effect of interest-rate protection agreements,
which were terminated on March 14, 1997 in connection with the retirement of
this facility.

     In order to fully realize the net deferred tax assets at December 27, 1997,
the Company will need to generate future taxable income of approximately $90
million. Management believes that it is more likely than not that the Company's
deferred tax asset will be realized as a result of future taxable income,
expected to be generated based on the Company's reasonable projections of future
earnings. The Company anticipates that increases in taxable income will result
primarily from (i) future projected revenue and gross margin growth through the
addition of new restaurant chains and the expansion of services provided to new
and existing restaurant chains, (ii) a reduction in interest expense due to a
reduction in its indebtedness, (iii) cost savings through its corporate and
network consolidation plan and (iv) other cost-reduction initiatives. In
addition, management believes reasonable tax planning strategies and other
potential transactions will be available that could be used to realize the
deferred tax asset before the expiry of any material net operating losses, which
will not begin to occur until after 2010.
 
     At December 28, 1996 and December 27, 1997, other current assets included
income taxes receivable of approximately $1.5 million and $0.4 million,
respectively, which consisted primarily of overpayments of tax liabilities and
pending carryback refund claims. United States federal income tax returns for
fiscal years 1992 and 1993 are currently under examination by the Internal
Revenue Service. A preliminary assessment is pending which is not material to
the consolidated financial position or results of operations as of December 27,
1997.
 
9. EMPLOYEE BENEFIT PLANS
 
  (a) Defined-Contribution Plans
 
     On January 1, 1997, the Company's defined contribution plan, which covers
substantially all employees, was renamed the ProSource Retirement Advantage
Plan. Eligible employees can contribute up to 15% of base
 
                                    F-13
<PAGE>   16
                                PROSOURCE, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
compensation, with the following benefits: (i) Company contributions of 2
percent, (ii) additional Company matching of 50 percent of the first 6 percent
contributed by the employee, and (iii) vesting of Company contributions ratably
over four years of service.
 
     The Company also had a Money Purchase Plan which covered those former NAD
salaried employees not covered by a defined-benefit plan. Under this plan, the
Company contributed 10 percent of eligible salary. The Money Purchase Plan was
terminated effective December 1996.
 
     The amount of contribution expense incurred by the Company for these plans
was approximately $2.2 million, $2.7 million and $1.5 million for fiscal years
1995, 1996 and 1997, respectively.
 
  (b) Defined-Benefit Pension Plans
 
     In conjunction with the changes to the ProSource Retirement Advantage Plan
in 1997, the Company terminated all three noncontributory defined-benefit
pension plans covering substantially all employees except those covered by
multiemployer pension plans under collective-bargaining agreements. The Company
settled all pension obligations related to these terminated plans in 1997
through (i) the purchase of annuities, (ii) lump-sum payments, or (iii) the
transfer of plan benefits into the ProSource Retirement Advantage Plan, at the
participant's discretion. The accrued liability as of December 28, 1996 was
adequate to cover the unfunded termination liability of these three pension
plans.
 
     Pension costs of approximately $0.9 million and $1.1 million reflected in
the consolidated statements of operations for fiscal years 1995 and 1996,
respectively, were determined based on actuarial studies. The Company's pension
expense for contributions to the various multiemployer pension plans under
collective-bargaining agreements was approximately $0.9 million, $1.2 million,
and $1.1 million for fiscal years 1995, 1996 and 1997, respectively.
 
10. STOCKHOLDERS' EQUITY
 
     Under the ProSource, Inc. Employee Stock Purchase Plan (the "Stock Plan"),
officers and key employees of the Company ("Management Employees") purchased a
total of 408,100 shares of Class B common stock at $10.00 per share in 1992,
132,500 shares of Class B common stock at $11.00 per share in 1993 and 1994, and
270,000 shares of Class B common stock at $10.00 per share in 1995 and 1996. In
connection with the purchases of Class B common stock, each Management Employee
entered into a Management Shareholders Agreement with the Company and Onex.
 
     The ProSource, Inc. Amended Management Option Plan (1995) (the "1995 Option
Plan") provides certain Management Employees with options to purchase one-half
the number of shares of Class B common stock purchased under the Stock Plan at
the same price per share paid by such stockholder (either $10.00 or $11.00).
Subject to the 1995 Option Plan, options granted under the 1995 Option Plan are
exercisable until December 31, 2000. No additional options will be granted under
the 1995 Option Plan. The 1995 Option Plan was amended in November 1996 to
provide that all unvested options vest at a rate of 10% per year through
December 31, 1999, when all remaining options vest. As a result, the Company
recorded a pretax charge in 1996 of $1.2 million reflecting the difference
between the market price of the Company's Class A common stock on the date of
amendment and the exercise price of such options.
 
     Under the 1996 Stock Option Plan (the "1996 Option Plan"), the Company may
grant options to its employees for up to 550,000 shares of Class B common stock.
In 1996 and 1997, the Company granted options to purchase 358,000 and 16,000
shares, respectively, of Class B common stock at $14.00 per share. Options under
the 1996 Option Plan vest ratably over four years from the date of grant. These
options cannot be exercised, however, until the earlier of (i) the date on which
the market value of the Company's common stock is 25% greater than the exercise
price and (ii) the eighth anniversary of the date of grant. Subject to the
 

                                    F-14

                                PROSOURCE, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
provisions of the 1996 Option Plan, vested options may be exercised for a period
of up to 10 years from the date of grant.
 
     Under the ProSource, Inc. 1997 Directors Stock Option Plan (the "1997
Directors Plan"), which was approved by the shareholders in April 1997, the
Company may grant options to its directors, who so elect to receive such options
in lieu of fees, to purchase shares of Class A common stock at $4.00 per share
below the stated fair market value on the date of grant. Options to purchase up
to 100,000 shares of Class A common stock may be granted under this plan. In
April 1997, the Company granted options to purchase 10,500 shares of Class A
common stock at $5.25 per share. Options under the 1997 Directors Plan vest and
become exercisable one year from the date of grant, provided that the holder
thereof is still a director of the Company at such time. Subject to the
provisions of the 1997 Directors Plan, options may be exercised for a period of
up to 10 years after the vesting date. During the year ended December 27, 1997,
the Company recognized $28,000 of compensation expense associated with this
plan.
 
     A summary of the status of the Company's three option plans for the years
ended December 30, 1995, December 28, 1996, and December 27, 1997 is as follows:

     During fiscal year 1996, the Company adopted SFAS No. 123. Under the
provisions of the new standard, the Company elected to continue using the
intrinsic-value method of accounting for stock-based compensation plans granted
to employees under Accounting Principles Board Opinion No. 25 and provide
pro-forma disclosure for the fair-value based method of accounting for
compensation costs related to stock-option plans and other forms of stock-based
compensation under SFAS No. 123.
 
     The Company estimated the weighted-average fair value of each option
granted during 1995, 1996 and 1997 at $8.27, $7.34 and $5.41, respectively. The
fair value of these options was computed at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for 1995, 1996 and 1997, respectively: risk-free interest rates of
6.3%, 6.2% and 6.3%; dividend yields of 0.0% for all years

presented, volatility factors of the expected market price of the Company's
common stock of 33.0% for all years presented and a weighted-average expected
life of the options of 7, 7 and 5 years, respectively.
 
     The Black-Scholes option valuation model was developed for use in computing
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
     For purposes of pro forma disclosures, the computed fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows (in thousands, except per share data).

     In conjunction with the acquisition of NAD, the Company issued warrants to
Martin-Brower. At December 28, 1996 and December 27, 1997, the warrants were
exercisable for 283,425 shares of Class B common stock at $12.35 per share
during the period from April 1, 1997 through March 31, 2000, and upon
consummation of certain transactions.
 
     On November 15, 1996, the Company completed the issuance of 3,400,000
shares of Class A common stock (at a price of $14.00 per share) through an
initial public offering, resulting in net proceeds to the Company of
approximately $43.2 million, after deducting underwriting discounts and
commissions, and other offering costs of approximately $4.4 million. The net
proceeds of the offering were used: (i) to prepay $15 million in outstanding
principal and $1.1 million in accrued interest under a subordinated note payable
to Onex; (ii) to prepay, at a discount, $10 million in outstanding principal and
$0.1 million in accrued interest under a subordinated note payable to
Martin-Brower for a total payment of $9.2 million and (iii) to repay $16.6
million of outstanding indebtedness under the Company's revolving-credit
facility, after deducting a $1.3 million payment concurrent with the offering
for the termination of a consulting agreement between the Company and certain
former owners of an acquired company. Also in connection with the initial public
offering, the Company incurred a noncash charge of $4 million resulting from the
issuance to Onex of 285,714 shares of Class B common stock valued at the initial
public-offering price in exchange for the agreement of Onex to relinquish its
rights to receive an annual fee, previously paid in cash, for management
services rendered to the Company.
 
     Under the ProSource, Inc. 1997 Employee Stock Purchase Plan, which was
approved by the shareholders in April 1997, employees of the Company purchased a
total of 33,799 shares of Class A common stock at $6.035 per share in 1997. In
January 1998, an additional 30,336 shares of Class A common stock were purchased
by employees at $6.035 per share under this plan.
 
11. CONTINGENCIES AND GUARANTEES
 
     The Company has guaranteed the principal due on certain loans obtained by
its officers and employees in connection with the purchase of common stock under
the Stock Plan. At December 27, 1997, such guarantees amounted to approximately
$0.8 million and were covered by a letter of credit. At December 27, 1997, the
Company was also obligated for $15.0 million in other letters of credit issued
on behalf of the Company primarily as a guarantee of payment for obligations
arising from workers' compensation claims. At Decem-

ber 27, 1997, the Company had $9.2 million available in unused letters of credit
under its Existing Credit Facilities.
 
     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.
 
12. CONCENTRATIONS OF CREDIT RISK
 
     Burger King Corporation ("BKC") owned and franchisee-owned Burger King
restaurants collectively accounted for 45%, 41% and 46% of the Company's sales
in fiscal years 1995, 1996 and 1997, respectively. Sales to BKC-owned
restaurants represented approximately 5% of sales for each of the aforementioned
years. Amounts due from BKC-owned restaurants at December 28, 1996 and December
27, 1997 were $5.5 million and $5.8 million, respectively.
 
     In addition, sales to Darden Restaurants, Inc. (owner of Red Lobster and
Olive Garden restaurants) accounted for 18%, 20%, and 21% of the Company's sales
in fiscal years 1995, 1996 and 1997, respectively. Amounts due from Darden
Restaurants, Inc. at December 28, 1996 and December 27, 1997, were approximately
$41.1 million and $41.4 million, respectively.
 
     Sales to company-owned and franchisee-owned Arby's restaurants accounted
for 10% of Company sales in fiscal years 1995 and 1996. No other customer or
restaurant concept accounted for more than 10% of the Company's sales in fiscal
years 1995, 1996 or 1997. The Company periodically performs credit evaluations
on its customers' financial condition and generally does not require collateral.
 
13. CUMULATIVE EFFECT OF A CHANGE IN ACCOUNTING PRINCIPLE
 
     During the fourth quarter of 1997, the Financial Accounting Standards
Board's Emerging Issues Task Force reached a consensus on Issue No. 97-13,
"Accounting for Costs Incurred in Connection with a Consulting Contract or an
Internal Project that Combines Business Process Reengineering and Information
Technology Transformation." The consensus requires that the cost of business
process reengineering activities, whether done internally or by third parties,
is to be expensed as incurred. As a result, any remaining unamortized portion of
previously capitalized business process reengineering costs is required to be
written off. The cumulative impact of initially conforming to this new standard
in the fourth quarter of 1997 was reported as a change in accounting principle
in the accompanying consolidated statements of operations, with a cumulative
charge, net of tax, of $6.4 million, or $0.69 per share.
 
14. NET LOSS PER SHARE
 
     For all years presented in the accompanying consolidated statements of
operations, 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
numerator and denominator of the basic and diluted loss per share computations.

15. SUBSEQUENT EVENT
 
     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 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. 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 merger is expected to close
in the second quarter of fiscal 1998.

                   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 Redline 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

INTRODUCTORY INFORMATION

On May 21, 1998, AmeriServe Food Distribution, Inc. (the Company), a Delaware
corporation and wholly owned subsidiary of Nebco Evans Holding Company (NEHC),
became the owner of all of the capital stock of ProSource, Inc., a Delaware
corporation (ProSource), pursuant to the merger (the Merger) of Steamboat
Acquisition Corp., a Delaware corporation and wholly owned subsidiary of the
Company (Merger Sub), with and into ProSource with ProSource as the surviving
corporation. At the effective time of the Merger, ProSource became a wholly
owned subsidiary of the Company and an indirect wholly owned subsidiary of NEHC.

The Merger was consummated pursuant to an Agreement and Plan of Merger (the
Merger Agreement), dated as of January 29, 1998, by and among the Company,
Merger Sub and ProSource. The Merger Agreement was approved and adopted by the
stockholders of ProSource at a special meeting held on May 20, 1998. In the
Merger, each share of ProSource Class A Common Stock, par value $0.01 per share,
and each share of ProSource Class B Common Stock, par value $0.01 per share was
converted into the right to receive $15.00 in cash without interest. The total
cash outlay in connection with the Merger was $313.5 million including the
acquisition of the capital stock, the repayment of $159.5 million of outstanding
indebtedness of ProSource and the direct costs of the Merger. The sources of
funds used in the Merger included cash on hand, a $50 million capital
contribution to the Company from NEHC and $125 million in proceeds from the sale
of certain trade receivables of ProSource under the Company's existing accounts
receivable securitization program with Bank of America, a commercial paper
conduit administered by Bank of America NT&SA and a group of other banks.

Effective June 11, 1997, the Company acquired certain operations of the PFS
Division of PepsiCo, Inc. (PFS) in an asset purchase transaction for
approximately $842 million in cash including direct costs. Financing of the
acquisition was effectively provided by proceeds from the issuances of $500
million 10 1/8% Senior Subordinated Notes due July 15, 2007 and $350 million 8
7/8% Senior Notes due October 15, 2006. Other financing activities at the time
of the acquisition included an equity contribution to the Company from NEHC of
$130 million, repayment of $134 million in outstanding borrowings under a
previously existing credit facility and the sale of certain trade receivables of
the Company and PFS under the accounts receivable securitization program
providing proceeds of $225 million. The excess of proceeds received from
financing activities over the PFS acquisition cost provided cash on hand to fund
costs of integrating the PFS operations and to later partially fund the
ProSource acquisition.

In connection with the acquisition of PFS and the Merger, the Company had
anticipated receiving additional proceeds under the accounts receivable
securitization program of approximately $80 million. This transaction was
completed in July 1998. The Company utilized a portion of its available credit
facilities to fund working capital requirements until the July 1998 transaction.

The Unaudited Pro Forma Consolidated Statements of Operations for the Year Ended
December 27, 1997 and the Six Months Ended June 27, 1998 assume the acquisitions
of ProSource and PFS, which have been accounted for under the purchase method,
were consummated at the beginning of fiscal 1997.

An Unaudited Pro Forma Consolidated Balance Sheet has not been presented because
the acquisition of ProSource is reflected in NEHC's Consolidated Balance Sheet
as of June 27, 1998 included in NEHC's previously filed Quarterly Report on Form
10-Q for the quarter ended June 27, 1998.

In connection with the acquisitions of PFS and ProSource, the Company has
identified a number of consolidation and integration actions designed to improve
the efficiency and effectiveness of the combined organization's warehouse and
transportation network and operations support infrastructure. These actions
include construction of new strategically located warehouse facilities, closures
of a number of existing warehouse facilities and expansions of others,
dispositions of property and equipment, conversions of computer systems,
centralization of support functions, reductions in workforce and relocation of
employees. The ultimate cost savings expected to be achieved after completion of
these actions, which are underway and are expected to be substantially completed
by mid-2000, are estimated to be approximately $100 million annually. No pro
forma adjustments for such cost savings are reflected in the Unaudited Pro Forma
Consolidated Statements of Operations.

The Company has begun to incur certain incremental, nonrecurring expenses
associated with actions to consolidate and integrate the PFS, ProSource and
previous acquisitions. These integration costs, which are expected to total
$25-50 million over the consolidation and integration period, consist primarily
of start-up costs of new facilities and other temporary inefficiencies arising
from the warehouse and transportation network reconfiguration, as well as
computer system conversion, employee relocation and other costs to realign the
operations support infrastructure. Integration costs actually incurred are
included in "Impairment, restructuring and other unusual charges" in the
accompanying Unaudited Pro Forma Consolidated Statements of Operations. No pro
forma adjustments are reflected in these pro forma financial statements for
additional estimated integration costs that would have been incurred had the
acquisitions of PFS and ProSource occurred at the beginning of fiscal 1997.
