                                   (UNAUDITED)

NOTE 1 - GENERAL

         The accompanying unaudited consolidated financial statements have
been prepared in accordance with the instructions and requirements of Form
10-Q. Consequently, they do not include all the disclosures required under
generally accepted accounting principles for complete financial statements.
However, in the opinion of the management of Miami Computer Supply

herein 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 and its consolidated subsidiaries.
The results of operations for the period ended September 30, 1999 are not
necessarily indicative of the results that may be expected for the entire

financial statements, refer to the consolidated financial statements and
notes included in the Company's Annual Report on Form 10-K for the year ended

</TABLE>

         The pro forma statement of operations data reflect the effects of
the purchase price allocation and the resultant amortization and additional
interest expense associated with the cash used to fund the acquisitions,
along with other adjustments directly attributable to the transactions. The
pro forma data reflects adjustments directly related to the acquisitions and
does not include adjustments that may arise as a consequence of the
acquisitions, such as cost savings, improved efficiencies, etc. Therefore,
the pro forma data is not necessarily indicative of operating results that
would have occurred for the nine month period ended September 30, 1998, or in
future periods, had the acquisitions actually occurred on January 1, 1998.

NOTE 3 - COMPREHENSIVE INCOME

         Comprehensive income was $8,026 and $4,105 for the nine months ended
September 30, 1999 and 1998, respectively and $2,907 and $1,785 for the

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

         The following discussion should be read in conjunction with the
information contained in the unaudited consolidated financial statements and
Notes to unaudited consolidated financial statements. The following
information contains "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995 (the "Act") and is subject
to the safe harbor created by that Act. The words "estimate," "project,"
"anticipate," "expect," "intend," "believe," "plans" and similar expressions
are intended to identify forward-looking statements. Because such
forward-looking statements involve risks and uncertainties, there are
important factors that could cause actual results to differ materially from
those expressed or implied by such forward-looking statements. Factors that
could cause actual results to differ materially include, but are not limited
to, changes in general economic and business conditions, the availability of
capital on acceptable terms, actions of competitors and key suppliers, risks
inherent in acquiring, integrating and operating new businesses, exchange
rate fluctuations, the regulatory and trade environment (both domestic and
foreign), and changes in business strategies and other factors as discussed
in Exhibit 99.

         The Company intends to continue its aggressive acquisition strategy
of entering new markets domestically and internationally on an opportunistic
basis, to acquire computer and office automation supply and audio-visual
presentation products distribution and integration companies, and to hire
certain experienced sales representatives in and outside of the Company's
current market areas, some of whom may be constrained from working in their
present locations for a period of time. The Company actively continues to
evaluate other potential acquisitions and to identify and have preliminary
discussions and negotiations with potential acquisition candidates. There can
be no assurance that any acquisition can or will be consummated on terms
favorable to the Company or at all or that the Company will not need
additional debt or equity financing to continue its acquisition strategy.

THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THREE MONTHS ENDED
SEPTEMBER 30, 1998

         NET SALES. Net sales for the three months ended September 30, 1999
increased by $106.3 million, or 141%, to $181.8 million from $75.5 million
for the three months ended September 30, 1998.

         GROSS PROFIT.  Gross profit for the three months ended September 30,
1999 increased by $19.2 million or 114% to $36.1 million from $16.9 million
for the three months ended September 30, 1998.  Gross profit as a percentage
of net sales for the three months ended September 30, 1999 was 20% compared
to 22% for the three months ended September 30, 1998.  The decrease in gross
profit is due to the portion of Axidata's business, which was purchased in
December 1998, derived from wholesale sales, which has lower margins than the
Company as a whole.

         SELLING GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses for the three months ended September 30, 1999
increased by $15.3 million, to $28.7 million from $13.4 million for the three
months ended September 30, 1998. The majority of the increase resulted from
the acquisitions the Company has completed since June 30, 1998. As a
percentage of net sales, selling, general and administrative expenses were
16% for the three months ended September 30, 1999 compared to 18% for the
three months ended September 30, 1998.

         OPERATING INCOME. Operating income for the three months ended
September 30, 1999 increased by $3.9 million to $7.4 million from $3.5
million for the three months ended September 30, 1998 for the reasons stated
above. Operating margin decreased to 4% for the three months ended September
30, 1999 compared to 5% for the three months ended September 30, 1998.

         INTEREST EXPENSE. Interest expense for the three months ended
September 30, 1999 increased by $2.3 million to $2.6 million from $348,000
for the three months ended September 30, 1998 due primarily to the increased
level of indebtedness during 1999, utilized to fund business combinations and
the growth in working capital.

         PROVISION FOR INCOME TAXES. The provision for income taxes for the
three months ended September 30, 1999 increased $667,000 to $2.1 million from
$1.4 million for the three months ended September 30, 1998. The Company's
effective tax rate was 43% for the three months ended September 30, 1999 and
44% for the three months ended September 30, 1998.

September 30, 1999 increased to $7.2 million from $1.6 million for the nine
months ended September 30, 1998 due primarily to the increased level of
indebtedness during 1999, which was used for business combinations and
working capital.

         PROVISION FOR INCOME TAXES. The provision for income taxes for the
nine months ended September 30, 1999 increased $3.0 million to $6.3 million
from $3.3 million for the nine months ended September 30, 1998. The Company's
effective tax rate was 45% for the nine months ended September 30, 1999 as
compared to 44% for the corresponding period of the prior year.

LIQUIDITY AND CAPITAL RESOURCES

         Net cash flows used in operating activities totaled $2.2 million for
the first nine months of 1999 compared to $10.3 million used by operating
activities during the first nine months of 1998. The change in net cash flows
from operating activities was due primarily to higher net income,
depreciation and amortization and an increase in accounts payable.

         Net cash used in investing activities was $18.1 million for the nine
months ended September 30, 1999 versus $31.6 million for the nine months
ended September 30, 1998. The net cash used in investing activities primarily
reflects the acquisitions completed during the period. Net cash provided by
financing activities totaled $20.8 million for the nine months ended
September 30, 1999 compared with $41.9 million for the nine months ended
September 30, 1998.

         Capital expenditures for the nine months ended September 30, 1999
totaled $7.9 million and were used primarily to upgrade the Company's management
information systems.

         The Company believes that its cash on hand and borrowing capacity
under the Credit Facility (see below) will be sufficient to fund its ongoing
operations and budgeted capital expenditures for the next twelve months,
although actual capital needs may change, particularly in connection with
acquisitions which the Company may make in the future. The Company's
long-term requirements, including capital expenditures and acquisitions, are
expected to be financed by a combination of additional borrowings and other
sources of external financing as needed. There can be no guarantee that such
financing will be available to the Company on favorable terms or at all.

YEAR 2000

         Year 2000 problems may disrupt our business. We are aware of the
issues associated with the hardware, software and operating systems in
existing computer and telecommunication systems as the next millennium
approaches. The "Year 2000" problem is pervasive and complex as virtually
every computer operation will be affected in some way by the rollover of the
two digit year value to 00. The issue is whether computer and other computer
operated systems will properly recognize date-sensitive information when the
year changes to 2000. Systems that do not properly recognize such information
could generate erroneous data or cause a system to fail. We are utilizing
internal and external resources to identify and correct, or reprogram, all of
our systems for Year 2000 compliance. Our AS/400hardware







                                       9

and operating system are already compliant. We recently have implemented a
corporate wide financial and distribution software package from J. D.
Edwards Company, at a cost of approximately $7.9 million, in response to
our expansion and acquisition program. We believe this software package is
already Year 2000 compliant. All subsidiaries with known Year 2000 problems
have been converted to the J. D. Edwards Company software package as of the
date hereof. All other equipment is currently undergoing compliance testing
which is expected to be completed by November 30, 1999. Equipment identified
as not Year 2000 compliant will be replaced. This equipment includes personal
computers, networking equipment, telecommunication equipment, phone and alarm
systems. Because most of our computer and telecommunications equipment is
relatively new, the cost to bring it into compliance is currently estimated to
be less than $250,000. We regularly carry products and accessories
manufactured by over 500 original equipment manufacturers.
Approximately 54.2% of our net
sales for the year ended December 31, 1998, were provided by our top ten
suppliers. We believe that our third party vendors and suppliers are
substantially Year 2000 compliant. Should a significant number of our
suppliers not be Year 2000 compliant, we might not be able to supply our
customers with product on a timely basis. Such a disruption could have a
material adverse effect on our operation and financial performance. No one
knows the extent of the potential impact of the Year 2000 problem generally
and we cannot predict the likelihood that Year 2000 problems will cause a
significant disruption in the economy as a whole. We will continue to examine
the Year 2000 issue as it potentially impacts us and will develop a
contingency plan if we believe one is necessary.

CREDIT FACILITY

         On August 31, 1999, the Company revised its then existing lending
arrangements with a consortium of banks. An amended and restated credit facility
of $150.0 million was provided by PNC Bank, N.A. and four other banks and
matures on December 10, 2003. Borrowings under the credit facility are
classified as long term debt. The credit facility enables the Company to borrow
funds and repay funds during the term of the agreement and contains restrictive
covenants which include, among other restrictions: (i) the maintenance of
certain financial ratios; (ii) restrictions on ( a ) the purchase or sale of
assets, ( b ) any merger, sale or consolidation activity, ( c ) loans,
investments and guarantees made by the Company, ( d ) lease and sale and
leaseback transactions, and ( e ) capital expenditures; and (iii) certain
limitations on the incurrence of other indebtedness. In addition, the credit
facility prohibits the payment of dividends and certain repurchases of the
Company's common stock. The Credit Facility is collateralized by substantially
all of the Company's assets. The interest rate for the credit facility is based
upon either the LIBOR rate plus a variable spread (2% at September 30, 1999) or
the prime rate (8 1/4% at September 30, 1999).
