BARRISTER GLOBAL SERVICES NETWORK, INC.
NOTES TO FINANCIAL STATEMENTS

1. In the opinion of Management, the accompanying financial statements present
fairly the financial position, results of operations and cash flows for the
periods shown. The second quarter results for each year represent operations for
the quarters ended September 30, 2000 and September 30, 1999. The financial data
included herein was compiled in accordance with the same accounting policies
applied to the Company's audited annual financial statements. Any adjustments
made were of a normal recurring nature.

         The results of operations for the six month period ended September 30,
2000 are not necessarily indicative of the results to be expected for the full
year.

2. Cash and equivalents consist of cash and liquid debt instruments with
maturities of three months or less from the date of purchase. Cash and
equivalents are stated at cost plus accrued interest, which approximates market
value. Short-term investments are classified as held-to-maturity securities
based on the Company's ability and intent to hold the securities until maturity.
The securities have a term of six months and are recorded at amortized cost
adjusted for the accretion of discounts or cost plus accrued interest.

3. On May 5, 2000, the Company sold substantially all of the assets of the
Company's software business to Keystone Solutions US, Inc. ("Keystone"), a
wholly owned subsidiary of Keystone Software PLC. The selling price was
$8,000,000 in cash plus the assumption by Keystone of certain liabilities. The
selling price is subject to adjustment in the event that the net assets
delivered differ from amounts stipulated in the agreement or if there are any
contingent, hidden or undisclosed liabilities relating to the purchased assets
or the software business. The Company has agreed to indemnify Keystone with
respect to any breach of its representations and warranties (subject to a
$50,000 basket and a cap of the purchase price paid) or any breach of any
covenant of the Company contained in the Asset Purchase Agreement. The Company
has also agreed to indemnify Keystone with respect to claims or actions pending
at or arising after the closing date (May 5, 2000) that relate to the operation
of the software business prior to that date. Of the selling price, $800,000 is
held in escrow for the payment of any of the above claims. In November $311,000
of the escrow was paid to Keystone regarding certain of these claims.
Approximately $200,000 of the escrow will be released to the Company in its
third quarter. The balance of the escrow less payment for additional claims, if
any, will be paid in equal amounts over an additional six months.

         The pre-tax net gain on the sale of the software business was
$3,467,000. The gain excludes the amount held in escrow. Any amounts received
from the escrow funds will be recorded in the period of receipt. The net gain
less applicable income taxes (see note 4) is shown in the statements of
operations under the caption discontinued operations. For the six month period
ended September 30, 1999, revenues from discontinued operations were $3,470,000
and a loss of $23,000 was incurred.

         4. The income tax provision associated with the gain from the sale of
the software business (see note 3) is higher than the statutory tax rate since
goodwill valued at $986,000 on the books had a zero basis for tax purposes. The
provision includes current taxes of $894,000 and deferred taxes of $800,000. The
deferred taxes resulted from the use of tax loss carryforwards from prior years,
the reversal of temporary differences between book and tax on the assets sold
and the temporary difference created by the treatment of the proceeds held in
escrow.

         The Company had no current tax expense or benefit in the quarter or six
months ended September 30, 1999 from continuing or discontinued operations due
to its operating loss. No deferred taxes were recognized in the first six months
of the prior year since changes in the net deferred tax asset were fully offset
by changes in the valuation allowance.

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

FINANCIAL CONDITION

         The Company experienced a net increase in cash and short-term
investments of $4,460,000 for the first six months of fiscal 2001. Proceeds from
the sale of the Company's software business on May 5, 2000, less associated
expenses, amounted to $6,623,000. Certain of the proceeds were used to repay
$711,000 of current and long-term debt, $674,000 of accounts payable and
$296,000 of accrued compensation and benefits. As a result, the Company's cash
and short term investments increased from $161,000 at March 31, 2000 to
$4,621,000 at September 30, 2000. The principal cash requirements expected for
fiscal 2001 are additions to equipment and leasehold improvements which are
expected to increase over amounts spent in prior years, primarily for a
telephone system and computer equipment. Debt repayments, including the
repayments made during the first six months, should approximate $876,000. The
Company's cash and short term investments will be sufficient to cover working
capital, capital expenditure requirements and debt repayments in fiscal 2001.

RESULTS OF OPERATIONS

         For the quarter ended September 30, 2000, revenues increased 28.0% from
the same quarter in 1999. For the six month period ended September 30, 2000,
revenues increased 27.7% compared with the first six months of the prior year.
These increases resulted from growth in revenues from hardware maintenance
contracts and from services provided on a time and materials basis. For the
comparative second quarters, revenues from hardware maintenance contracts grew
to $2,073,000, an increase of 27.6% and for the comparative first six months
these revenues grew to $3,894,000, an increase of 23.2%. These increases
principally resulted from the capture of new contracts, primarily through the
Company's reseller channel. Time and material revenues increased by 30.1% to a
total of $623,000 for the comparable second quarters and by 42.2% to a total of
$1,170,000 for the comparative six month periods. Business generated from two
customers that commenced in the second and fourth quarters of last year was the
primary reason for these increases.

         The cost of services decreased as a percentage of revenues from 75.6%
in the second quarter of the prior year to 75.1% in the second quarter of the
current year. For the comparable first six months, these expenses decreased as a
percentage of revenues from 79.5% to 74.8%. The principal reason for these
decreases is reduced levels of expense associated with the service parts
inventory.

         Selling, general and administrative expenses were 31.0% of revenues for
the second quarter of this year compared to 35.0% of revenues for the comparable
quarter last year. For the comparable six month periods, these expenses were
31.1% of revenues compared to 37.5% of revenues in the previous year. The
primary reason for these decreases is that the increases in revenues have been
achieved without any growth in the general and administrative costs of the
company. Any increases in these costs have been offset by staff reductions based
on the sale of the software business of the Company to Keystone Solutions US,
Inc. in May 2000.


         Interest income was earned in the second quarter and first six months
of the current year







                                       9

based on income received on the investment of the net proceeds from the sale of
the software business. These proceeds were also used to pay certain outstanding
interest bearing debt of the Company.

         The Company had no current tax expense or benefit in the quarter or six
months ended September 30, 1999 due to its operating loss. No deferred taxes
were recognized in the first six months of the prior year since changes in the
next deferred tax asset were fully offset by changes in the valuation allowance.

         The pre-tax net gain on discontinued operations is based on the sale of
the Company's software business to Keystone on May 5, 2000. The income tax
provision associated with the gain from the sale of the software business is
higher than the statutory tax rate since goodwill valued at $986,000 on the
books had a zero basis for tax purposes. The provision includes current taxes of
$894,000 and deferred taxes of $800,000. The deferred taxes resulted from the
use of tax loss carryforwards from prior years, the reversal of temporary
differences between book and tax on the assets sold and the temporary difference
created by the treatment of the proceeds held in escrow.

         The increase in the weighted average number of common shares
outstanding resulted from the conversion of all of the preferred stock into
2,500,000 shares of common stock in September, 1999, and the issuance of 283,000
shares as stock bonuses or upon the exercise of stock options since the second
quarter of the prior year.
