BARRISTER GLOBAL SERVICES NETWORK, INC.
NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

1. Barrister Global Services Network, Inc. (the "Company") provides a variety of
IT services for a broad range of multi-vendor computer related equipment
including personal computers and equipment generally attached to local area
networks, point of sale terminals and related equipment, and on-site,
mission-critical repair, depot repair and warranty repair services. This
comprehensive maintenance and warranty service is done on a contractual and time
and materials basis. These services are provided through a network of service
locations throughout the United States.

         The accompanying unaudited condensed financial statements have been
prepared in accordance with accounting principles generally accepted in the
United States of America ("GAAP") for interim financial information and with the
instructions to Form 10-QSB and Article 10 of Regulation S-X. Accordingly, they
do not include all of the information required by GAAP for complete financial
statement presentation. In the opinion of management, all adjustments
(consisting only of normal recurring adjustments) necessary for a fair
presentation of financial position, results of operations, and cash flows have
been included. Operating results for the period ended June 30, 2003 are not
necessarily indicative of the results to be expected for other interim periods
or the full year. These financial statements should be read in conjunction with
the financial statements and accompanying notes contained in the Company's Form
10-K for the fiscal year ended March 31, 2003. This report represents the
Company's first time filing Form 10-QSB, previously the Company had been filing
under Form 10-Q.

2. Cash and equivalents consist of cash and liquid debt instruments with
maturity 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 at June 30, 2003 contain held-to-maturity securities,
based on the Company's ability and intent to hold the securities until maturity.
The held-to-maturity securities are recorded at amortized cost adjusted for the
accretion of discounts or cost plus accrued interest. At March 31, 2003,
short-term investments also included shares of Principal Financial Group, Inc.
("Principal") common stock received in the demutualization of Principal,
classified as available for sale securities with net unrealized gains or losses,
if any, reported as a separate component of stockholders' equity, net of tax.
The Company sold the Principal common stock during the quarter ended June 30,
2003 for a gain of $52,000.

3. On July 15, 2002, the Company acquired all of the outstanding stock of
Advantage Innovation, Inc. ("Advantage") for $1,200,000 in cash and future
consideration of two contingent payments due on the first and second
anniversaries of the closing. The Stock Purchase Agreement was amended in
January 2003 to remove the previous contingent payment provision and replace
them with installment payment provisions due July 31, 2003 and July 31, 2004 for
$1,250,000 each, unless certain conditions are not met in which event each of
the payments would be reduced by $531,000 to $719,000. Consequently the Company
has accrued for a total of $1,438,000 at June 30, 2003. In the event that all of
the contingencies related to the installment payments are met the Company would
accrue up to $2,500,000. Subsequent to these Financial Statements, on July 31,
2003 the first of the two installments payments was made in the amount of
$1,250,000 of which $719,000 is included in short term debt on the balance
sheets and $531,000 became additional Goodwill on July 31, 2003. Advantage was a
privately held technical and computer services firm located in New Orleans,
Louisiana performing repair services on personal computers and home appliances
for insurance companies who provide warranties on such equipment. The
acquisition has been accounted for as a purchase and, accordingly, the

                                       7

<PAGE>

operating results of Advantage have been included in the Company's financial
statements since the date of acquisition. The assets acquired and liabilities
assumed were recorded at estimated fair values based on fair values at the date
of acquisition. Liabilities assumed in this acquisition were $810,000. The
excess of the initial purchase price over fair value of the net assets acquired
was approximately $2,411,000, of which $219,000 was allocated to identifiable
intangible assets and $2,192,000 has been allocated to goodwill. The pro forma
results for the quarter ended June 30, 2002, had the acquisition occurred at the
beginning of the period, are as follows: Revenues of $4,009,000; net earnings of
$171,000; and net earnings per common share, basic and diluted of $.01. The pro
forma amounts do not purport to be indicative of the actual results that would
have occurred had the transaction been consummated on April 1, 2002 or of the
future results of operations which will be obtained as a result of the
consummation of the transaction.

4. The Company has adopted Statement of Financial Accounting Standards No. 148,
"Accounting for Stock-Based Compensation - Transition and Disclosure". This
standard provides alternative methods of transition for a voluntary change to
the fair value based method of accounting for stock-based employee compensation.
Additionally, the standard also requires prominent disclosures in the Company's
financial statements about the method of accounting used for stock-based
employee compensation, and the effect of the method used when reporting
financial results.

5. In June 2002 the Company received 14,159 shares of Principal common stock
issued to the Company in connection with the demutualization of Principal. The
shares issued pertained to the Company's defined benefit pension plan which had
been terminated in 1991. The value of these shares was recorded in total other
income for the quarter ended June 30, 2002. The shares were subsequently sold in
June 2003 for a net gain of $52,000. Changes in the fair market value of the
shares during the holding period were shown in accumulated other comprehensive
income or loss, as the asset was considered to be an available-for-sale
security.

6. The weighted average common shares used in the computation of basic and
diluted earnings per share were as follows:

</Table>

7. No employee stock based compensation expense was reported for the quarters
ended June 30, 2003 or June 30, 2002, since any options are granted with
exercise prices equal to the market value per share. Had the Company determined
compensation cost based on the fair value of the options at grant date, the
reported net loss of June 30, 2003 would be increased to $(330,000) or $(.03)
per share and the reported earnings for June 30, 2002 would be decreased to
$86,000 or $.01 per share.

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

RESULTS OF OPERATIONS

         For the quarter ended June 30, 2003, revenues decreased approximately
6.9% from the same quarter in 2002. Revenues from hardware maintenance contracts
decreased 27.3% for the quarter to $1,660,000 from $2,282,000 for the first
quarter of the prior year. This reduction primarily resulted from the
non-renewal of a large contract by a customer of one of our long-time business
partners as of September 30, 2002. This decrease was partially offset from
growth in services provided on a time and materials basis which increased by
54.0% for the comparative first quarters, from $803,000 to $1,237,000. The
principal reason for this increase was revenues generated from the business
acquired on July 15, 2002 from Advantage Innovation, Inc. ("Advantage").

         The cost of services decreased as a percentage of revenues from 78.8%
in the first quarter of the prior year to 76.8% in the first quarter of the
current year. This improvement primarily resulted from a lower cost of
contracted service providers supplied by the business acquired from Advantage
and used to service calls in the current quarter on a Company wide basis.

         Selling, general and administrative expenses were 36.0% of revenues for
the first quarter of this year compared to 30.0% for the comparative quarter
last year. The principal reasons for this increase was expenditures for outside
consultants currently assisting the Company in strategic decisions, the
increased rent expense of the Company's new headquarters and operations center,
higher depreciation expenses related to assets acquired in the prior year, and
amortization expense from the intangible assets acquired from the Advantage
purchase in July of 2002. Additionally some portion of the general and
administrative expenses are relatively fixed and become an increased percentage
on the lower revenue attained.

         The decrease in net interest income for the comparative first quarters
resulted from lower interest rates and a reduction in amount invested. For the
quarter ended June 30, 2003 other income resulted from a gain recognized on the
sale of 14,159 shares of Principal Financial Group, Inc. common stock received
in June 2002 in connection with the demutualization of Principal. Total other
income for the quarter ended June 30, 2002 primarily resulted from the receipt
of those shares.

         No additional tax benefits were established in the statements of
operations for the quarter ended June 30, 2003, since the Company has fully
reserved for the tax effect of net deductible temporary differences and loss
carryforwards. These benefits will be recorded in future periods as they are
realized or as their realization becomes predictable. Income taxes recorded in
the prior year first quarter approximated the statutory tax rate.

FINANCIAL CONDITION

         Cash and equivalents, short-term investments and marketable securities
totaled $2,223,000 at June 30, 2003 and $2,785,000 at March 31, 2003. The net
decrease of $562,000 was primarily a result of net cash used by operating
activities of $537,000

         On July 15, 2002, the Company acquired the stock of Advantage
Innovation, Inc. for an initial cash payment of $1,200,000, with two additional
and conditional payments on the first and second anniversaries of the closing.
The Agreement provides for installment payment

                                       9

<PAGE>

provisions due July 31, 2003 and July 31, 2004 for $1,250,000 each, unless
certain conditions are not met in which event each of the payments would be
reduced to $719,000. The first of these payments ($1,250,000) was subsequently
made on July 31, 2003.

         In addition to the July 31, 2003 cash payment made to Advantage, the
principal cash requirements expected for fiscal 2004 are debt repayments of
$151,000 and normal additions to equipment and leasehold improvements. The
Company's cash and investments will be sufficient to cover working capital,
capital expenditure requirements and debt repayments in fiscal 2004 only if the
Company is successful in increasing its revenues or decreasing its costs, or in
obtaining additional financing. There can be no assurance that it will be able
to generate positive cash from operations or that sufficient cash will be
available to meet its required needs and obligations.

AMEX LISTING

         In June of 2002, the Company announced that it was informed by the
American Stock Exchange (AMEX) that it had fallen below certain of the
Exchange's continued listing standards. The Company submitted a plan to AMEX
that would return the Company to profitability by March 31, 2003, which it
failed to meet. In addition, the Company has not been able to regain compliance
with the exchange's continued listing standards through the quarter ended June
30, 2003. The Company expects to receive de-listing notice in the near future.
If the Company is delisted, trading of our common stock may be conducted in the
over-the-counter market on the "pink sheets" or, possibly, the NASD's
"Electronic Bulletin Board". In either of these cases, investors could find it
more difficult to buy or sell, or to obtain accurate quotations as to the value
of our common stock. Also the trading price per share of our common stock likely
would be reduced as a result.

NEW ACCOUNTING PRONOUNCEMENTS

          The Company has adopted Statement of Financial Accounting Standards
No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure".
This standard provides alternative methods of transition for a voluntary change
to the fair value based method of accounting for stock-based employee
compensation. Additionally, the standard also requires prominent disclosures in
the Company's financial statements about the method of accounting used for
stock-based employee compensation, and the effect of the method used when
reporting financial results.

FORWARD-LOOKING STATEMENT

         When used in this report, the words "expects", "believes" and "intends"
and similar expressions are intended to identify forward-looking statements.
Such statements are subject to certain risks and uncertainties which could cause
actual results to differ materially from those projected. Readers are cautioned
not to place undue reliance on these forward-looking statements which speak only
as of the date hereof. The company undertakes no obligation to republish revised
forward-looking statements to reflect events or circumstances after the date
hereof or to reflect the occurrences of unanticipated events. Readers are also
urged to carefully review and consider the various disclosures made by the
Company which attempt to advise interested parties of the factors which affect
the Company's business in the Company's periodic reports on Form 10-K and 10-QSB
filed with the Securities and Exchange Commission.

ITEM 4.  EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

         (a)      Evaluation of disclosure controls and procedures. Our chief
                  executive officer and our chief financial officer, after
                  evaluating the effectiveness of the Company's "disclosure
                  controls and procedures" (as defined in the Securities
                  Exchange Act of 1934 Rules 13a-14 and 15d-14 as of a date (the
                  "Evaluation Date") within 90 days before the filing date of
                  this quarterly report, have concluded that as of the
                  Evaluation Date, our disclosure controls and procedures were
                  adequate and designed to ensure that material information
                  required to be disclosed in reports that are filed or
