                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - GENERAL

The accompanying unaudited consolidated financial statements have been prepared
in accordance with Rule 10-01 of SEC Regulation S-X.  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 Corporation (the "Company"), the
consolidated financial statements presented 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.  For further information regarding the Company's
accounting policies and the basis of presentation of the 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 December 31, 1996.

NOTE 2 - ORGANIZATION

The Company sells a wide variety of computer supplies to corporate customers,
governmental agencies, universities, hospitals and, to a lesser extent, computer
supply dealers.  Its primary sales products include laser toner, ink jet
cartridges, printer ribbons, computer tape cartridges, diskettes, presentation
products, paper supplies and printer cartridges.

NOTE 3 - ACQUISITION OF DDP

Effective May 30, 1996, Pittsburgh Investment Group, LLC ("LLC") contributed its
stock in Diversified Data Products, Inc. ("DDP") to the Company. The acquisition
has been accounted for using the purchase method of accounting, and accordingly,
the purchase price has been allocated to the assets based upon the fair value of
the liabilities assumed as of May 30, 1996.

In connection with the acquisition of DDP, LLC issued a loan to certain former
stockholders in an amount of $250,000.  This amount was subject to repayment
based upon DDP generating specified income levels for the period May 30, 1996 to
December 31, 1996.  DDP generated such income levels for this period, and
accordingly the loan was forgiven.  The value of the assets acquired has been
adjusted to reflect this additional consideration.

The operating results of DDP have been included in the statement of operations
from the date of acquisition. The following unaudited pro forma information has
been prepared assuming that this acquisition had taken place at the beginning of
the respective period. This pro forma financial information is presented for
informational purposes only and may not be indicative of what the actual results
of operations might have been if the acquisition had been effective at the
beginning of 1996.

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

The following discussion should be read in conjunction with the information 
contained in the (unaudited) Consolidated Financial Statements and Notes to 
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 changes in business strategies and other factors as 
discussed in Exhibit 99.

The Company intends to implement an aggressive acquisition strategy of entering
new markets domestically and internationally on an opportunistic basis, to
acquire computer and office automation supply distribution 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 

                                  6

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.

THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31, 1996

NET SALES. Net sales for the three months ended March 31, 1997 increased by $7.7
million, or 61.1%, to $20.2 million from $12.6 million for the three months
ended March 31, 1996.  Approximately 79.5% of the increase resulted from the
acquisition of DDP on May 30, 1996. The remaining increase was primarily a
result of increased sales to the Company's current customer base.

GROSS PROFIT. Gross profit for the three months ended March 31, 1997 increased
by $1.0 million, or 37.8% to $3.5 million from $2.5 million for the three months
ended March 31, 1996. Gross profit as a percentage of net sales for the three
months ended March 31, 1997 was 17.2% compared to 20.1% for the three months
ended March 31, 1996. The decrease in the gross profit percentage was due
primarily to the acquisition of DDP which had lower operating gross margins
primarily due to volume discounts associated with sales to other computer supply
dealers.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses for the three months ended March 31, 1997 increased by
$0.8 million, or 44.4% to $2.7 million from $1.9 million for the three months
ended March 31, 1996.  Approximately 19.4% of the increase resulted from
increased salary expenses, while 9.1% was due to increased commission expense
resulting from the Company's increased sales volume. The remainder of the
increase related primarily to the acquisition of DDP.  As a percentage of net
sales, selling, general and administrative expenses were 13.4% for the three
months ended March 31, 1997 compared to 15.0% for the three months ended March
31, 1996. This decrease as a percentage of sales reflects the Company's ability
to support increased sales volumes without a significant increase in its
overhead structure.

OPERATING INCOME. Operating income for the three months ended March 31, 1997
increased by $0.2 million to $0.8 million from $0.6 million for the three months
ended March 31, 1996 for the reasons stated above.

INTEREST EXPENSE. Interest expense for the three months ended March 31, 1997
decreased by $66,067 or 98.7% to $871 from $66,938 for the three months ended
March 31, 1996 due primarily to the decreased level of indebtedness during 1997.

PROVISION FOR INCOME TAXES. The provision for income taxes for the three months
ended March 31, 1997 increased $0.1 million to $0.3 million from $0.2 million
for the three months ended March 31, 1996.  The Company's effective tax rate was
40.5% for the three months ended March 31, 1997 as compared to 41.5% for the
corresponding period of the prior year.

LIQUIDITY AND CAPITAL RESOURCES

Net cash flows used in operating activities totaled $1.4 million for the first
three months of 1997 compared to $.02 million provided by operating activities
during the first three months of 1996. The change in net cash flows from
operating activities in the first three months of 1997, compared to the first
three months of 1996, was due primarily to an increase in working capital as the
Company supported its expanded business activities. Working capital amounted to
$10.7 million at March 31, 1997 compared to $10.2 million at December 31, 1996.
The increase in working capital resulted primarily from an increase in accounts
receivable and inventories.

Net cash used in investing activities remained consistent at $.06 million for
the three months ended March 31, 1997 and March 31, 1996. Net cash provided by
financing activities totaled $0.8 million for the three months ended March 31,
1997 compared with $.04 million for the three months ended March 31, 1996. This
increase was due primarily to increased borrowing under the Credit Facility.

Capital expenditures for the three months ended March 31, 1997 of $59,787 were
used primarily to upgrade the computer system at DDP, the Company's marketing
department and a new Nashville, TN sales office.

For fiscal year 1997, the Company expects capital expenditures of approximately
$0.3 million (comprised of approximately $0.2 million to be used for upgrading
and enhancing the Company's MIS and approximately $0.1 million for capital
maintenance items).  Actual expenditures for fiscal 1997 may be greater than
budgeted amounts depending on the level of acquisition activity and other
factors.

The Company believes that its cash on hand, borrowing capacity under the Credit
Facility, capital resources and cash flows will be sufficient to fund its
ongoing operations and budgeted capital expenditures for the remainder of 1997,
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 internally generated funds, additional borrowings
and other sources of external financing as needed.

CREDIT FACILITY

On September 11, 1996, the Company increased the amount of its line-of-credit
from $6,500,000 to $15,000,000 in order to facilitate the planned expansion of
the Company's business activities, including acquisitions. The amount of the
Credit Facility that will be available to the Company may not exceed the lesser
of $15.0 million or an amount equal to the sum of: (i) 85.0% of the net book
value of all eligible receivables (i.e., those receivables less than 90 days
old, except that all receivables from any particular customer will be ineligible
if more than 15.0% of the total due from such customer are aged 90 days or more)
plus (ii) an amount equal to the lesser of either 50.0% of the value of all
inventory, not to exceed 45.0% of the aggregate unpaid principal balance less
the amount secured by inventory acquired by the Company from Hewlett-Packard
Company and not yet paid for, or if advances are made against foreign accounts
receivables, not to exceed $2.0 million (the "Borrowing Base"). Under the Credit
Facility, the Company's borrowing availability at March 31, 1997 approximated
$9.7 million. At March 31, 1997, $0.8 million was outstanding under the Credit
Facility.

The Borrowing Base may be changed by the Bank, in its sole discretion, from time
to time. Borrowings under the Credit Facility bear interest, at the Company's
option, (i) on amounts in excess of $500,000, at the applicable London Interbank
Offered Rate ("LIBOR") per annum determined by the Bank plus 2.0%, adjustable at
the end of each contract period (one, two, three, four or six months), as
defined in the Credit Facility, or (ii) at the Bank's applicable prime rate (as
defined in the Credit Facility). Interest on the Credit Facility is payable in
arrears on the last day of each month and at maturity, except that interest on
loans bearing interest utilizing the LIBOR option is payable on the last day of
the contract period and at maturity, unless the contract period is longer than
90 days in which case interest is payable every three months.

The indebtedness under the Credit Facility is secured by substantially all of
the assets of the Company, including accounts receivable, equipment and
inventory. In addition, the Credit Facility requires that the Company maintain a
tangible net worth of $3.2 million in 1997 and thereafter increasing by an
amount equal to 50.0% of the Company's net income annually thereafter, maintain
a debt to tangible net worth ratio of 450.0% and annual pre-tax interest
coverage (net income plus interest expense plus income tax) of 150.0% or more of
the Company's annual interest expense. The Company was, at March 31, 1997 and is
as of the date hereof, in compliance with these financial covenants.
