            TEKINSIGHT.COM AND DATA SYSTEMS NETWORK CORPORATION SIGN
              ACQUISITION AGREEMENT SUBJECT TO SHAREHOLDER APPROVAL

New York, New York - February 29, 2000--TekInsight.com, Inc. (NASDAQ:TEKS), a
provider of advanced Internet and e-commerce products and solutions, and Data
Systems Network Corporation (OTC BB: DSYS), a leading provider of enterprise
services, today jointly announce that they have signed a definitive Agreement
and Plan of Merger.

Under the terms of the agreement approved by Data Systems' and TekInsight.com's
Boards of Directors, Data Systems shareholders will receive a varying purchase
price for Data Systems (the "Merger Price") which will equal $12,500,000 if the
market price of TekInsight's common stock (the "Market Price") at the time of
the closing is less than $5.00 per share, $16,000,000 if the market price is
between $5.00 and $7.00 per share, and $18,000,000 if the market price is over
$7.00 per share. The Merger Price will be delivered to Data Systems shareholders
through the distribution of a number of shares of a new class of TekInsight.com
Convertible Preferred Stock proposed to be listed on the NASDAQ Small Cap
market, with the number of such shares to be found by dividing the applicable
Merger Price by the Market Price at the time of the closing. The agreement is
subject to approval by the shareholders of Data Systems and TekInsight.com,
acceptance by NASDAQ for the listing of the Convertible Preferred Stock, and
additional customary closing conditions. There can be no assurance that Nasdaq
listing will be obtained for the newly issued Convertible Preferred Stock, or
that any of the other closing conditions will be satisfied.

Steve Ross, CEO and President of TekInsight.com, said "The acquisition of Data
Systems will not only enhance our existing Internet infrastructure, but will
also give TekInsight.com critical value-added sales channels for new products
which we intend to bring to market."
