                                     PART I

ITEM 1.                    BUSINESS

GENERAL

         Barrister Information Systems Corporation (the "Company") is a national
supplier of Windows-based and browser-based client server software for law
firms, accounting firms, consultants and departments of Fortune 1000 companies.
The Company is also a national provider of equipment maintenance services.

         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.

         In January 1999, the Company acquired the assets of Icon Technology
LLC, including its software product LegalHouse. This organization was made part
of the Company's software business.

         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.

         The Company segments discussed below are the Software Business Segment
and the Equipment Maintenance Services Business Segment which account for all of
the Company's revenues.

SOFTWARE BUSINESS

         The Company's Software Business develops, markets, licenses and
installs software for law firms, accounting firms, consultants and departments
of Fortune 1000 companies. The organization of this operating segment includes
staff which provide the functions of marketing, sales, development,
installation, conversion, project management, training, hot line support and
consulting.

         Approximately 78 people are employed in this business. The majority of
the staff are located in Buffalo, New York with a development office in San
Rafael, California. Some sales and customer support representatives reside
outside the principal offices.

SOFTWARE MARKET

         The Company was the first to offer and install an all Window's-based
firm management software package for medium to large sized law firms. The
Company now sells its Windows-based client server software product, Javelan; its
browser-based JavelanX software product; Javelan Select, a scaled down version
of Javelan for smaller

                                    Page -2-


<PAGE>   3



firms; LegalHouse, an Executive Information and budgeting package; and software
support services principally to the U.S. law firm market and to law firms in
Canada and the Caribbean. The Company's software products are used by law firms
for firm management and to track 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, budgeting, collections,
general ledger and accounts payable. Those products are 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
products are distinguished from its competitors' products by their performance,
functionality, product design and 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 the Company's legal market press
releases and advertising literature. The Company is expanding marketing by
establishing strategic relationships which will enhance sales in the legal
market in the United States and internationally. Further, staff has been added
to pursue sales opportunities in commercial markets..

         The Company believes that its existing clients using older non-Javelan
software present significant opportunities for sales of additional software and
services. By marketing to and communicating with existing clients opportunities
are anticipated to license Javelan as replacement software. Further, efforts are
being directed to ensuring client satisfaction and facilitating additional sales
of services and add-on software to Javelan clients. 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 its product, to install
these products and train clients in its use and to support the client afterward.

         The Company has made a substantial investment in the Javelan, JavelanX
and LegalHouse products and protects its intellectual property rights by trade
secret, by copyright and 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 software packages. The choice of features will be
driven by clients through periodic 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 and LegalHouse.

         Historically, software product life cycles have been relatively short.
With the markets using Windows browser interfaces 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 the Company's software packages 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.

                                    Page -3-


<PAGE>   4



         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 products of the Company are Javelan, Javelan Select,
JavelanX and LegalHouse. Javelan is a state-of-the-art software package and can
operate on Windows 95, Windows 98 or NT Workstation and provides the functions
necessary for law firm 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. In the next year the product will
operate on SQL-Server 7.0. Javelan Select, a product aimed at smaller firms uses
a scaled down set of Javelan software for this market segment. JavelanX is the
newest version of Javelan. It will operate on the firms WAN or over the Internet
using standard browsers.

         LegalHouse is a product that was developed by Icon Technology, LLC
which was acquired in January 1999. This software package uses a sophisticated
data warehouse to provide powerful and unique management reporting and
budgeting. It is being marketed through seminars, through the traditional sales
and marketing techniques of the Company and through strategic relationships. The
market potential for the product includes all larger law firms, professional
organizations and corporations in both the United States and international.

         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.

         Javelan, Javelan Select, JavelanX and LegalHouse 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 will support until December 1999:

           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.

         Clients have been notified that the Eagle, Time Manager, and CFMS
products are not Y2K compliant, that the Company has not invested in these
obsolete products to make them Y2K compliant and will not support them after
December 1999. 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 and Javelan Select products are being offered to these
clients.

SOFTWARE SERVICES

         Upon the sale of a license for any of the Company's software packages,
the client generally contracts for a number of services to aid with the
installation of the software. These services include project management,
training, data conversion, custom programming, consulting and installation
support and post installation services. These services are generally billed to
the client on an as-incurred basis.

         The Company also schedules regular training classes for clients to
educate new employees or to teach advanced subjects. Finally, with the
acquisition of the assets and the hiring of the employees of Icon Technology
LLC, the Company expects to see an increase in general computer system
consulting to the legal and corporate markets.

         Software services are an important and growing source of revenue in the
Company's Software Business.

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. Expenditures for product development and
engineering, before taking into account amounts capitalized and amortized for
software production costs, were $904,000, $842,000 and $700,000 in fiscal 1999,
1998, and 1997, respectively. For fiscal 2000, the Company expects its level of
spending in this area to increase over 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 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.

EQUIPMENT MAINTENANCE SERVICES BUSINESS

         From the mid-1970's to about 1989, the Company manufactured
mini-computers and other equipment as part of the Barrister System, sold
principally to the law firm market. A nationwide organization was established to
support these clients and maintain the Barrister equipment..

         When the Company stopped the manufacture of mini-computers, the service
organization continued support of the Barrister customers and implemented a
strategy to diversify into the maintenance of desktop computer equipment. In
1989, 100% of service revenues came from the maintenance of Barrister
mini-computers and equipment. Today nearly 100% of equipment maintenance
services derive from desktop equipment.

SERVICES MARKET

         The Company provides equipment maintenance services nationwide for
desktop equipment including personal computers and other equipment which attach
to LANs. Using its staff of hardware technicians and third party service
companies, the Company provides comprehensive maintenance services for such
equipment. The Company provides a nationwide toll-free number for customer
service and provides a seven-day, twenty-four hour maintenance capability.

         In 1998, the Company took the initiative and developed and licensed
several software modules and integrated them into an Internet-based software
system which provides unique and innovative ways to provide and manage equipment
maintenance services to its clients. This integrated software system is called
Barrister Global Service Network (GSN) and allows for clients anywhere in the
world to view the status of service calls. Further the system provides
management information to client and company managers responsible for service
delivery. Finally, GSN provides a mechanism over the Internet to transmit
service requests to third party subcontractors, to monitor and manage those
service calls and to measure service delivery performance. The ability to manage
third party service providers and provide summary management information is a
unique and powerful capability. This capability has received favorable comment
as a valuable value-added service from clients and prospects. It is anticipated
this capability will lead to substantial positive changes in the national
service delivery process.

         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 Pioneer-Standard Electronics, Inc., IBM Corporation, U.S. Computer, Amherst
Computer Products, Amdahl 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

                                    Page -6-


<PAGE>   7



a dependable and cost effective basis to customers with multiple locations
throughout the U.S.

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 1999, revenues from the subcontracts were
approximately 10% of total revenues.

OFFICES

         Maintenance services are provided by employees located in offices
throughout the United States and by subcontractors. The Services business
employs about 94 of the Company's staff of which 45 are in Buffalo, New York and
the balance in offices in New York City, Hartford, Washington, D.C., Atlanta and
Cleveland.

EMPLOYEES

         As of June 8, 1999, the Company had 194 full-time employees and 8
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", "JAVELAN", JAVELANX" and "LEGALHOUSE"
and trademarks in certain other names used in its business. The Company has no
patents or patent applications pending.

Board of Directors

Barrister Information Systems Corporation:

Under date of June 28, 1999, we reported on the balance sheets of Barrister
Information Systems Corporation as of March 31, 1999 and 1998, and the related
statements of operations, shareholders' equity and cash flows for each of the
years in the three-year period ended March 31, 1999, as contained in the 1999
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, 1999. In connection with our audits of the aforementioned
financial statements, we also have audited the related financial statement
schedule as listed in item 14(a)(2) of this the annual report on Form 10-K. This
financial statement schedule is the responsibility of the Company's management.
Our responsibility is to express an opinion on this financial statement schedule
based on our audits.

In our opinion, such financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly, in all
material respects, the information set forth therein.
