            TEKINSIGHT.COM LAUNCHES TEKINSIGHT E-GOVERNMENT SERVICES

    New e-government unit uses extensive experience to build Internet-enabled
         infrastructure and applications for state and local government

NEW YORK - MAY 18, 2000 - TekInsight.com (NASDAQ: TEKS-TEKSW), an Internet
development company that offers software and services based on its Streaming
XML(TM) technology and Data Systems Network Corporation (OTCBB: DSYS), a
provider of enterprise services with a focus on state and local governments,
announced today the formation of TekInsight e-Government Services
(http://egov.tekinsight.com), a joint marketing effort design to serve large and
medium-sized municipalities, states and government agencies. In January 2000,
TekInsight announced the intent to acquire Data Systems.

The formation of TekInsight e-Government Services follows TekInsight's
announcement that the company has completed the acquisition of bigtechnologies,
Inc., an Internet solutions firm specializing in the development of e-government
sites with advanced transactional applications, such as the one built for the
City of Boston.

"The Internet has changed the way the world conducts business, and it was only a
matter of time before governments looking to increase efficiency and deliver
better service followed suit. States, municipalities and government agencies
that have taken advantage of the Internet by offering online services to their
constituents are already receiving political and economic benefits," said Kyle
Tager, General Manager of TekInsight e-Government Services.

Tager continued, "We understand that government works because of the hard work
of committed employees. TekInsight e-Government Services is designed to make
their jobs easier, so they can make the lives of their constituents easier.
Ultimately, the people are what it's all about. And many of them have grown
cynical, expecting the worst in their dealings with government, and often
getting just that. If governments take steps to





                                      -2-

increase their efficiency and reduce their operating costs while providing
better, faster service, we're confident many of these people will change their
views."

Public Technology, Inc. (PTI) estimates that the majority of local governments
will be looking to take transactions online in the next year and virtually all
large and medium-sized governments will be looking to conduct online
transactions by 2002.

"Similar to private sector companies, governmental organizations are realizing
that to offer their services online, they must develop new ways to serve people
online," said Alexander Kalpaxis, Chairman and CTO of TekInsight.com.
"TekInsight's unique Streaming XML(TM) technology will let government workers
provide those services in real-time while allowing more cost-effective
development and deployment of their e-Government Services."

The TekInsight e-Government Services team first creates the municipality's Web
site, if the site is not already developed. After Web site development,
TekInsight will create and install an e-Government Operating System (OS), which
contains all of the important security features, including encryption, digital
signatures, imaging, credit card payment validation, and integration necessary
to protect constituents' transactions. The e-Government OS also allows employees
to access a server to locate a variety of "back-end" forms, enabling easy
updates to items such as community calendars, job postings, press releases and
directories.

Once the e-Government OS is installed, the e-Government Services team utilizes a
unique suite of software modules, each providing a different online service
tailored to the unique needs of the specific government's constituents. The
modules are "hooked" into existing Web sites and databases, allowing for a
seamless, real-time transfer of information. Additional modules will be added in
the future. Current modules include:

o    Tax/Violation Payments - Addresses all types of taxes and violations,
     allowing constituents to browse through pertinent information, look up what
     he or she owes, and make payments, all from the comfort of their home. And
     by utilizing back-end user tools, government employees can search for
     payments made, reconcile, post information, and create user-designed
     reports.

o    Permitting - This module is especially useful if a person is renovating a
     house or starting a business. Individuals and businesses can file permits
     online, 24 hours a day. Fees, if any, can be paid with a credit card, and
     back-end forms enable government employees to view and approve applications
     online.

o    Licensing - Provides forms in which the government can display information
     about how to obtain a license, the proper documentation required, and any
     renewal guidelines. The licensing module allows users to apply online for
     documents such as incorporation papers, driver's license renewals and
     marriage certificates.


                                      -3-

o    Deeds - Allows individuals to access all information pertaining to a deed
     and to view the actual deed images online prior to requesting certified
     copies. The deed module allows the government to accept payments for those
     copies.

o    Procurement - A major activity that all governments have in common is the
     need to procure items. Requests for Proposal (RFPs) are placed online to
     ensure maximum distribution. Each can be downloaded, printed and sent back
     through the mail or online. Customized reports can sort the responses for
     easy review and award. This module is currently under development.

o    My Government - With the "My Government" module, all of a constituent's
     information, from every department, can be found in one centralized
     location. For example, a user can verify that a payment was credited,
     search for the name of the local police captain, find out when certain
     voting polls close and discover whether his or her home remodeling permit
     application was approved.

The e-Government Services team can also install freestanding e-kiosks in
conveniently accessible areas. This will benefit those constituents that do not
have access to a computer, bridging the digital divide allowing for better
service to all of a government's constituents.

TekInsight e-Government Services' people have 15 years of experience installing
and upgrading total systems for government, in a quick and efficient fashion.
Successful implementations include e-Government initiatives with the City of
Boston (www.cityofboston.com), the Suffolk County Registry of Deeds
(www.suffolkdeeds.com), the State of Florida and the State of Louisiana.

AWARD-WINNING E-GOVERNMENT EXPERIENCE

The City of Boston e-government program has received awards from Government
Technology Magazine for the "Best of the Web" in local government, Yahoo!
Internet Life for a perfect "10" in content development and first place for
innovation on the web from Public Technology, Inc. (PTI).

TekInsight e-Government Services engagements include application development,
integration and support. TekInsight e-Government systems include full management
and trending features that allow for continuous status and performance
monitoring, ensuring that systems are highly available and running at peak
performance. Technical support help desks are available, 24 hours per day, seven
days a week.
