                                     PART I

ITEM 1.       BUSINESS

GENERAL

              Barrister Information Systems Corporation (the "Company") is a
national supplier of Windows-based client server software for law firms,
accounting firms, consultants and departments of Fortune 1000 companies. In
addition, the Company provides equipment maintenance services on a nationwide
basis.

              The Company was formed in 1972 as the Office Automation Division
of Comptek Research, Inc. ("Comptek"). On March 26, 1982, the division was
incorporated under the laws of New York as Barrister Information Systems
Corporation and was spun off to the Comptek shareholders as a separate company.
In July 1985, the Company sold shares of its common stock in its initial public
offering. The Company's shares are currently traded on the American Stock
Exchange. In December, 1997 the Company reincorporated under the laws of
Delaware.

              The Company's headquarters are at 465 Main Street, Buffalo, New
York 14203, telephone 716-845-5010. In addition, the Company has a number of
sales and services offices throughout the United States.


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
10K and 10Q filed with the Securities and Exchange Commission.


SOFTWARE MARKET

              The Company was the first to offer and install an all
Window's-based firm management software for medium to large sized law firms. The
Company now sells its Windows-based client server software product, Javelan, and
software support services principally to the U.S. law firm market and to law
firms in Canada and the Caribbean. Javelan software is used by law firms for
firm management and to keep track of the time of attorneys and paralegals to
enable them to bill their clients. In addition, the software provides the law
firm with other applications such as executive information, collections, general
ledger and accounts payable. Javelan is also being sold in the accounting,
consulting and corporate markets for organizations seeking time and billing or
time and cost allocation capability. The Company currently expects that the
majority of sales will come from the legal market.

              The markets pursued by the Company are concentrated in major
cities throughout the United States. There are numerous competitors which are
primarily U.S. companies and the technology barriers to enter the market are
low. However, the requirement for sophisticated functionality demands
substantial investment to develop products which can compete effectively in
these markets. Because of competition and market demands, there is a continuing
requirement to enhance the software to remain a viable competitor. Currently,
the Company believes that its product is distinguished from its competitors'
products by its performance, functionality, product design and

                                    Page -2-

<PAGE>   3



architecture.

              In its software marketing efforts for the legal market, the
Company conducts seminars in cities throughout the United States, advertises in
professional publications and provides demonstrations at its corporate
headquarters, regional offices, client locations and trade shows. The Company
also markets the systems to consultants to advise them of the system's features
and new product developments and to gain increased market acceptance.

              Marketing to the accounting, consulting and corporate segments to
date has consisted of follow through on leads and interest shown by prospects
attending legal trade shows and reading legal market literature. The Company
expects to expand marketing in this area by attending trade shows and group
conferences in those markets and by establishing strategic relationships which
will enhance sales in those segments.

              The Company believes that its existing clients present significant
opportunities for sales of additional software and services. Approximately 35%
of Javelan contracts to date have come from these clients. It is marketing to
and communicating with approximately 130 of its existing clients which have
licensed software in the past in order to license Javelan as replacement
software. Further, service efforts are directed to ensuring client satisfaction
and facilitating additional sales. The Company has sponsored the organization of
a national users group, comprised of representatives of clients, who meet with
Company personnel to exchange ideas and techniques for the use of the Company's
systems, provide training and offer suggestions for product development and
enhancements. The Company believes it has the staff with the necessary technical
and market knowledge to advance the product, to install the product and train
clients in its use and to support the client afterward.

              The Company has made a substantial investment in the Javelan
product and protects its intellectual property rights by licensing the software
by contract. Pricing is based on the size of the system and the functions
licensed. Clients pay recurring monthly license fees and, in return, receive
telephone support and periodic software enhancements. Investments are expected
to continue to enhance the features and functions of the Javelan software
package. The choice of features will be driven by clients through bi-annual user
group meetings. These investments are expected to increase the sales
opportunities in the existing client base and to improve sales in the markets
for Javelan.

              Historically, software product life cycles have been five to ten
years. With the markets moving to Windows and client/server architecture, there
may be a lengthening of the cycle. This effect is expected to intensify the
investment in features and functions and reduce investments in the underlying
technology and architecture of the product, which will be available in the open
market.

              Sales of Javelan software may occur from time to time and are not
predictable. As a result, the Company's performance from quarter to quarter can
change dramatically. Performance in a given quarter cannot predict results in
subsequent periods.

              The Company provides its systems and services under various
hardware purchase contracts, software license agreements, systems installation
and training agreements and hardware and software service contracts. Law office
personnel, often inexperienced in computer programming or operations, are
trained by the Company to use its systems. The Company's systems are capable of
communicating with computers and personal computers of other manufacturers.


PRODUCTS

              The principal product of the Company is Javelan, a
state-of-the-art software package, which can operate on either Windows 3.1,
Windows 95 or NT Workstation and provides the functions necessary for law firm

                                    Page -3-

<PAGE>   4



management using desktop computing and client server architecture. Javelan
software operates on the law firm's local area network (LAN) and uses PC work
stations on the LAN for data processing. A server using Microsoft SQL-Server
6.5 contains the law firm's data base and supports the work stations. Javelan
was introduced to the market in November 1992 through an extensive series of
seminars. In December 1994, the Company announced that Javelan would operate
with Microsoft NT and SQL-Server 6.0. Currently, Javelan is delivered with NT
and SQL-Server 6.5. During the year a version of Javelan, called Javelan Select,
a product aimed at smaller firms was released. Javelan and Javelan Select are
expected to contribute significantly to the Company's revenues in the future.

              In the past, the Company has developed or purchased several
products which it currently supports:

              EAGLE               Law firm management software which operates on
                                  IBM AS-400 computers.

              TIME MANAGER        Time and billing, accounting and accounts 
                                  payable software which operates on DOS for 
                                  smaller firms.

              CFMS                Law firm management software which operates on
                                  Barrister manufactured mini-computers.

              In addition to software which the Company has developed, the
Company resells software which functions compatibly with its products. Further,
the Company resells equipment such as database servers to clients who license
Javelan software. From time to time, the Company sells personal computers and
printers in support of clients.

              It is anticipated that most minicomputer, AS-400 and DOS-based
clients will migrate to systems using Windows and local area networks (LANs).
The Company's Javelan product, the first Window's based management system for
law firms, is being offered to these clients.


BACKLOG

              Because the Company typically ships products within a relatively
short period of time after a contract is signed, the backlog varies, is not
meaningful at any date and is not indicative of intermediate or long-term future
sales.


SOFTWARE DEVELOPMENT

              The markets for the Company's software products are characterized
by rapid technical changes which have required and will continue to require the
Company to engage in ongoing development, and evaluations, the future costs of
which are expected to be significant. Before taking into account amounts
capitalized as software production costs, the Company incurred $842,000,
$700,000 and $693,000 of product development and engineering expenses in fiscal
1998, 1997, and 1996, respectively. For fiscal 1999, the Company expects its
level of spending in this area to remain approximately the same as the prior
year.


INVENTORY

              Customers generally require rapid delivery and orders are usually
filled within 30 days. Most of the systems the Company provides use equipment
and software developed by third parties, which is generally available and in
many cases shipped directly by the vendors. Software developed by the Company
does not require large amounts of inventory. Consequently, the Company does not
keep significant amounts of product inventory in order to meet customer
requirements. The Company does not generally provide rights of return or
extended payment terms

                                    Page -4-

<PAGE>   5



to customers.


SOFTWARE COMPETITION

              The business of providing software and services to law offices is
highly competitive. The Company believes that the principal competitive factors
affecting a law office's choice of data processing systems are product quality,
performance and reliability, compatibility with industry standards, the ability
to provide ongoing, long-term customer service and support, hardware and
software features, ease of use, upgrading capabilities, customer training,
system flexibility, company financial stability, name recognition of product and
company. Price, while important, is not the dominant factor in client's buying
decisions.

              The Company competes with more than ten companies who are
developers of specialized software for law offices, many of which are
substantially larger and have substantially greater name recognition and
financial, marketing, technical and personnel resources than the Company.


SERVICES MARKET

              The Company provides equipment maintenance services nationwide for
PCs and other equipment which attach to LANs. Using its staff of hardware
technicians and LAN specialists, the Company provides comprehensive maintenance
services for such equipment. In addition, the Company occasionally uses third
parties as subcontractors to provide maintenance services in certain
geographical locations. The Company provides a nationwide toll-free number for
customer service and provides a seven-day, twenty-four hour maintenance
capability.

              Since 1972, the Company has established a field service
organization located in a number of cities throughout the United States. To
support them, a depot repair facility located in Buffalo, New York performs
repairs on equipment shipped to Buffalo. These resources have enabled the
Company to sell equipment maintenance service contracts outside the legal market
and to sell depot repair services. Currently, more than 90% of hardware
maintenance revenues are generated outside the legal market.

              Sales of services are the result of a direct sales force focused
on this market. A variety of service plans are offered which cover Barrister's
proprietary equipment to a long list of OEM micro-computer products. In
addition, the Company has established business relationships with companies such
as IBM Corporation, U.S. Computer, Amherst Computer Products and MRK
Technologies, Ltd. to provide services on a contractual basis.

              Since product life cycles for hardware are relatively short, the
Company provides updated training to its service technicians and continuously
reviews its spare parts inventory for potential obsolescence. The Company
believes there are sufficient technicians available to meet its business needs
and that adequate sources of parts will be available to meet technological and
product life cycle changes.


SERVICES COMPETITION

              Providing maintenance and repair depot services to clients is also
a highly competitive business. The principal competitive factors are price,
expertise, reputation and geographic location of staff. The Company competes
with numerous organizations which can provide similar maintenance services, many
of which are substantially larger, better known and have substantially greater
name recognition and financial, marketing, technical and personnel resources
than the Company. The Company believes it distinguishes itself by providing
services on a dependable and cost effective basis to customers with multiple
locations throughout the U.S.

<PAGE>   6



RELATIONSHIP WITH IBM

              The Company has received a number of hardware maintenance
subcontracts from IBM. These subcontracts are generally renewable on an annual
basis with 30 day cancellation rights. During fiscal 1998, revenues from the
subcontracts were approximately 17% of total revenues.



EMPLOYEES

              As of June 15, 1998, the Company had 185 full-time employees and 7
part-time employees. None of the Company's employees is represented by a labor
union and the Company has had no work stoppages. The Company believes that
employee relations are good.


PROTECTION OF PROPRIETARY INFORMATION

              The Company believes its proprietary software and hardware
technology is adequately protected by trade secret and copyright laws and
contracts with its customers, employees and suppliers. The Company has a
registered trademark and service mark in the names "BARRISTER" and "JAVELAN" and
trademarks in certain other names used in its business. The Company has no
patents or patent applications pending.

statements of operations, shareholders' equity and cash flows for each of the
years in the three-year period ended March 31, 1998, as contained in the 1998
annual report to shareholders. These financial statements and our report thereon
are incorporated by reference in the annual report on Form 10-K for the year
ended March 31, 1998. In connection with our audits of the aforementioned
financial statements, we also have audited the related financial statement

Our responsibility is to express an opinion on this financial statement schedule
