                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (unaudited)

1.  BASIS OF PRESENTATION

  The consolidated financial statements include the accounts of CompUSA Inc. and
its wholly owned subsidiaries (collectively, the "Company").  All significant
intercompany accounts and transactions have been eliminated.  In the opinion of
management, the accompanying unaudited consolidated financial statements contain
all adjustments, consisting only of normal recurring adjustments, necessary to
present fairly the financial position, results of operations, and cash flows of
the Company for the applicable interim periods.  The results of operations for
these periods are not necessarily comparable to, or indicative of, results of
any other interim period or for the fiscal year as a whole.

  The accompanying unaudited condensed 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
interim financial statements.  Therefore, these financial statements should be
read in conjunction with the Company's Annual Report on Form 10-K for the fiscal
year ended June 28, 1997.

  The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make certain
estimates and assumptions.  These estimates and assumptions affect the reported
amounts of assets, liabilities, revenues, and expenses and the disclosure of
gain and loss contingencies at the date of the consolidated financial
statements.  Actual results could differ from those estimates.


2.  EQUITY

  Income per common and common equivalent share is computed using the weighted
average number of shares of common stock and common stock equivalents
outstanding during each period.  If dilutive, the effects of stock options,
treated as common stock equivalents, are calculated using the treasury stock
method.

  On November 6, 1996, the Company's Board of Directors declared a two-for-one
stock split effected in the form of a stock dividend to stockholders of record
on November 18, 1996, payable on December 2, 1996.  Stock options and all other
agreements payable in the Company's common stock (the "Common Stock") were
amended to reflect the split.  Amounts equal to the par value of shares issued
in connection with the stock split have been transferred from additional paid-in
capital to the common stock account.  All references to the number of shares
(except for shares authorized) and income per common and common equivalent share
amounts for the thirteen weeks ended September 26, 1996, have been adjusted on a
retroactive basis to reflect the stock split.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                  (unaudited)

  In September 1997, the Company's Board of Directors authorized the purchase of
up to $60 million of Common Stock.  As of October 28, 1997, the Company had
purchased 620,000 shares of Common Stock, to be held as treasury stock, at a
weighted average price of $34.65 per share, excluding transaction costs.

  In December 1995, the Company's Board of Directors authorized the purchase of
up to $30 million of Common Stock. On December 22, 1995, the Company purchased
472,400 shares of Common Stock, to be held as treasury stock, at a weighted
average price of $7.44 per share, excluding transaction costs. On May 24, 1996,
the Company's Board of Directors rescinded the December 1995 authorization to
purchase Common Stock.


3.  COMMITMENTS AND CONTINGENCIES

  The Company is a defendant from time to time in lawsuits incidental to its
business.  Based on currently available information, the Company believes that
resolution of all known contingencies would not have a material adverse impact
on the Company's financial statements.  However, there can be no assurances that
future costs would not be material to results of operations of the Company for a
particular future period.  In addition, the Company's estimates of future costs
are subject to change as circumstances change and additional information becomes
available during the course of litigation.

4.  SUBSIDIARY GUARANTEES

  The Company's 9 1/2% Senior Subordinated Notes due 2000 (the "Senior
Subordinated Notes") are guaranteed on a full, unconditional, and joint and
several basis by all of the Company's direct and indirect subsidiaries, each of
which is wholly owned. The combined summarized information of these subsidiaries
is as follows:

ability of the Company's subsidiaries to declare and pay dividends to the
Company.

6.    NEW ACCOUNTING PRONOUNCEMENTS

  In February 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, "Earnings per Share," which the Company is required to adopt in
the second quarter ending December 27, 1997.  At that time, the Company will be
required to change the method currently used to compute earnings per share and
to restate all prior periods.  Under the new standard, the Company will be
required to disclose both "basic" and "diluted" earnings per share.  The
dilutive effect of stock options and other common stock equivalents is excluded
from the calculation of basic earnings per share but is included in the
calculation of diluted earnings per share using the treasury stock method.
Basic and diluted earnings per share calculated in accordance with the
provisions of SFAS 128 are as follows:

7.  CREDIT AGREEMENT

  Effective December 30, 1996, the Company entered into a new, three-year
unsecured revolving credit agreement (the "Credit Agreement") with a consortium
of fourteen banks that provides for borrowings and letters of credit up to a
maximum of $150 million with letters of credit not to exceed $75 million in the
aggregate.  The funds available under the Credit Agreement may be used for any
corporate purpose, including purchasing or redeeming the Senior Subordinated
Notes in part or in full.  At September 27, 1997, the Company had approximately
$149 million available for future borrowings after reduction for outstanding
letters of credit.

  Borrowings under the Credit Agreement bear interest, at the Company's option,
at either a prime rate (8.5% per annum as of September 27, 1997) or a rate based
on the London Interbank Offering Rate (LIBOR) ranging from 5.7% to 5.8% as of
September 27, 1997, plus a specified margin, currently 0.75%.  The Company also
pays certain commitment and agent fees.  The Company has the annual option to
extend the Credit Agreement for an additional year with the banks' approval.

  The Credit Agreement requires the maintenance of certain financial ratios and
a minimum tangible net worth.  The Credit Agreement, as amended, also imposes
limitations on mergers and consolidations and prohibits the purchase of Common
Stock in excess of $130 million and the payment of dividends (other than stock
dividends).  The Credit Agreement allows the Company to securitize up to
$100 million of certain assets. The indebtedness under the Credit Agreement is
guaranteed on a full, unconditional, and joint and several basis by all
subsidiaries of the Company.

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

CAUTIONARY STATEMENT REGARDING RISKS AND UNCERTAINTIES THAT MAY AFFECT FUTURE
RESULTS

  This Quarterly Report on Form 10-Q contains forward-looking statements about
the business, financial condition, and prospects of the Company.  The actual
results of the Company could differ materially from those indicated by the
forward-looking statements because of various risks and uncertainties, including
without limitation changes in product demand, the availability of products,
changes in competition, the ability of the Company to open new stores in
accordance with its plans, economic conditions, real estate market fluctuations,
interest rate fluctuations, dependence on manufacturers' product development,
various inventory risks due to changes in market conditions, changes in tax and
other governmental rules and regulations applicable to the Company, and other
risks indicated in the Company's filings with the Securities and Exchange
Commission.  The Company's recent entry into the build-to-order market with its
CompUSA PC/TM/ brand personal computers involves significant additional risks,
including, without limitation, failure to achieve customer acceptance of the new
products and substantial dependence on third parties for product quality and
reliability and timely fulfillment of customer orders.  All of the foregoing
risks and uncertainties are beyond the ability of the Company to control, and in
many cases, the Company cannot predict the risks and uncertainties that could
cause its actual results to differ materially from those indicated by the
forward-looking statements.  When used in this Quarterly Report on Form 10-Q,
the words "believes," "estimates," "plans," "expects," "anticipates," and
similar expressions as they relate to the Company or its management are intended
to identify forward-looking statements.

  The Company believes the opening of additional Computer Superstores/SM/ in
existing markets has resulted in some reductions in the rate of comparable store
sales growth.  CompUSA has opened additional stores in existing markets largely
to increase market penetration and to provide customers with more convenience
and better service.  The Company plans to continue its strategy of opening
additional Computer Superstores in existing markets.  The resulting diversion of
sales from existing stores may adversely affect the Company's comparable store
sales.  However, the Company believes that this strategy should increase its
awareness with local consumers, enhance its competitive position in such
markets, and create efficiencies in advertising and management, and therefore is
in the Company's long-term best interest.

RESULTS OF OPERATIONS

  As a result of the expansion of the Company's store base, period-to-period
comparisons of financial results may not be meaningful and the results of
operations for historical periods may not be indicative of the results to be
expected in future periods.  In addition, the Company expects that its quarterly
results of operations will fluctuate depending on the timing of the opening of,
and the amount of net sales contributed by, new stores and the timing of costs
associated with the selection, leasing, construction, and opening of new stores,
as well as seasonal factors, product introductions, and changes in product mix.
See "-Quarterly Data and Seasonality."  The following table sets forth certain
items expressed as a percentage of net sales for the periods indicated:

FIRST QUARTER ENDED SEPTEMBER 27, 1997, COMPARED WITH THE FIRST QUARTER ENDED
SEPTEMBER 28, 1996

  Net sales for the first quarter of fiscal 1998 increased 20.3% to $1.19
billion from $991 million for the first quarter of fiscal 1997.  The increase in
net sales was primarily due to the additional sales volume attributable to the
new stores opened subsequent to the first quarter of fiscal 1997 and an increase
in comparable store sales of 6.1%. The Company believes the increase in
comparable store sales was primarily due to the maturation of the Company's
store base, increased customer demand, and increased growth in the Company's
service businesses.

                                       11

  Gross profit was $176 million, or 14.7% of net sales, in the first quarter of
fiscal 1998, compared with $137 million, or 13.8% of net sales, in the first
quarter of fiscal 1997.  The increase in gross profit as a percentage of net
sales was primarily due to higher product margin, an improvement in controllable
costs such as inventory shrinkage and freight, and an increase in the ratio of
service revenues to total revenues.  Service revenues typically have higher
gross margins than merchandise sales.  The foregoing factors were partially
offset by an increase in occupancy costs related to 26 Computer Superstores
opened since the end of the first quarter of fiscal 1997.

  Operating expenses were $109.2 million, or 9.2% of net sales, in the first
quarter of fiscal 1998, compared with $90.5 million, or 9.1% of net sales, in
the first quarter of fiscal 1997.  In the first quarter of fiscal 1998, net
advertising expense decreased as a percentage of net sales and other operating
expenses increased as a percentage of net sales.  The decrease in net
advertising expense as a percentage of net sales resulted primarily from
increased vendor participation.  The increase in operating expenses as a
percentage of net sales is due partially to the increase in both new store net
sales and in the ratio of service revenues to total revenues.  These increases
in new store net sales and in the ratio of service revenues to total revenues
had the effect of increasing operating expenses as a percentage of net sales
because of the following factors: (1) operating expenses in general, and store
personnel expenses in particular, typically constitute a higher percentage of
net sales for less mature stores because of the lower sales volumes generated by
less mature stores and (2) operating expenses are generally higher for service
revenues than for merchandise sales.

  Pre-opening expenses consist primarily of personnel expenses incurred prior to
a store's opening and promotional costs associated with the opening.  The
Company's policy is to expense all pre-opening expenses in the month of the
store's grand opening.  In the first quarter of fiscal 1998, the Company
incurred $1.5 million in pre-opening expenses in connection with the opening of
five stores and the relocation of one store, compared with $897,000 in pre-
opening expenses incurred in the first quarter of fiscal 1997 in connection with
the opening of three stores.

  General and administrative expenses of $25.6 million, or 2.1% of net sales, in
the first quarter of fiscal 1998, remained relatively constant as a percentage
of net sales compared with $21.1 million, or 2.1 % of net sales, in the first
quarter of fiscal 1997.

  Interest expense and other income, net, of $1.1 million, or 0.1% of net sales,
in the first quarter of fiscal 1998 remained relatively constant as a percentage
of net sales compared with $792,000, or 0.1% of net sales, in the first quarter
of fiscal 1997.  See "-Liquidity and Capital Resources."

  The Company's effective tax rate was 38.5% for both the first quarter of
fiscal 1998 and the first quarter of fiscal 1997.

  As a result of the above, net income for the first quarter of fiscal 1998 was
$23.5 million, or $.25 per share, compared with net income of $14.5 million, or
$.15 per share, for the first quarter of fiscal 1997.

QUARTERLY DATA AND SEASONALITY

  The Company expects that its quarterly results of operations will fluctuate
depending on the timing of the opening of, and the amount of net sales
contributed by, new stores and the timing of costs associated with the
selection, leasing, construction, and opening of new stores, as well as seasonal
factors, product introductions, and changes in product mix.

  Based upon its past operating history, the Company believes that its business
is seasonal.  Excluding the effects of new store openings, net sales and
earnings are generally lower during the first and fourth fiscal quarters than in
the second and third fiscal quarters.

LIQUIDITY AND CAPITAL RESOURCES

  At September 27, 1997, total assets were $1.36 billion, $1.16 billion of which
were current assets, including $295 million of cash and cash equivalents.  Net
cash provided by operating activities for the first quarter of fiscal 1998 was
$106 million which was primarily attributable to the net income for the quarter
and an increase in the ratio of accounts payable to inventory.

  Approximately three-fourths of the Company's net sales during the first
quarter of both fiscal 1998 and fiscal 1997 were sales for which the Company
received payment at the time of sale either in cash, by check, or by third-party
credit card. The remaining net sales were primarily sales for which the Company
provided credit terms to corporate, government, and education customers.

  Merchandise inventories increased to $631 million at September 27, 1997 from
$501 million at June 28, 1997.  The increase in merchandise inventories is
primarily attributable to inventories at the five Computer Superstores opened in
the first quarter of fiscal 1998, higher inventories held by the Company's
configuration center, as well as inventories received in anticipation of
seasonal promotional sales to be held in the second quarter of fiscal 1998.

  Capital expenditures during the first quarter of fiscal 1998 were $21.2
million, of which $3.4 million were for fiscal 1998 new stores and $3.0 million
were for existing stores, compared with $18.0 million of capital expenditures
during the first quarter of fiscal 1997, of which $6.3 million were for fiscal
1997 new stores and $4.0 million were for existing stores.  In addition to the
capital expenditures incurred in connection with new stores, the Company also
incurred capital expenditures in the first quarter of fiscal 1998 and fiscal
1997 related to improvements made in information systems and additions to
property and equipment at the Company's corporate facilities.  Excluding the
effects of new store openings, the Company's greatest short-term capital
requirements occur during the second fiscal quarter to support a higher level of
sales in that quarter.  During fiscal 1998, the Company plans to open
approximately 30 to 40 new Computer Superstores and anticipates total capital
expenditures of approximately $110 to $120 million.  The Company believes its
available cash and cash equivalents and vendor and bank financing are sufficient
to satisfy its short-term capital requirements.

  The Company has an unsecured $150 million credit agreement (the "Credit
Agreement") with a consortium of banks that expires in December 1999.  The
Credit Agreement requires the maintenance of certain financial ratios and a
minimum tangible net worth and restricts, among other things, the Company's
ability to incur additional indebtedness.  However, the Credit Agreement allows
the Company to securitize up to $100 million of certain assets.  See Note 7 of
Notes to Consolidated Financial Statements.  At September 27, 1997, the Company
had approximately $149 million available for future borrowings after reduction
for outstanding letters of credit.  The Company also finances certain fixture
and equipment acquisitions through equipment lessors.  Lease financing is
available from numerous sources and the Company evaluates equipment leasing as a
supplemental source of financing on a continuing basis.

                                       13
<PAGE>
 
  The Company believes that its available cash and cash equivalents, funds
generated by operations, currently available vendor and floor plan financing,
lease financing, and funds available under the Credit Agreement should be
sufficient to finance its continuing operations and expansion plans through the
end of fiscal 1998 and to make all required payments of interest on the Senior
Subordinated Notes.  The level of future expansion will be contingent upon the
availability of additional capital.

INFLATION

  While inflation has not had, and the Company does not expect it to have, a
material impact upon operating results, there can be no assurances that the
Company's business will not be affected by inflation in the future.
