                     DATA SYSTEMS & SOFTWARE INC. ANNOUNCES
        RESULTS FOR THE SECOND QUARTER AND SIX MONTHS ENDED JUNE 30, 2005

Mahwah, New Jersey - August 12, 2005 -- Data Systems & Software Inc. (OTCBB:
DSSI) today announced results for the quarter and six months ended June 30,
2005.

      Sales in the first six months of 2005 increased by $1.1 million, from
$14.6 million in the first six months of 2004 to $15.7 million in the first six
months of 2005. This increase was due to increased sales in both segments,
particularly in the first quarter of this year. Sales in the second quarter of
2005 decreased in comparison to those in the second quarter of 2004. The
decrease in sales was due to a $0.5 million decrease in computer hardware sales,
partially offset by a $0.3 million increase in software consulting and
development sales.

         Gross profit in the first six months of 2005 increased by $0.2 million
compared to the first six months of 2004, due to increased gross profit in both
segments in the first quarter of this year. Gross profit in the second quarter
of 2005 decreased by $0.1 million in comparison to the second quarter of 2004,
due a decrease in gross profit in the Company's computer hardware segment.

         Selling, marketing, general and administrative expenses in the first
six months and second quarter of 2005 increased by $0.3 million and $0.2
million, respectively, as compared to the same periods in 2004. The increase was
due to increased compensation expenses and professional fees. Although the
Company expects this increased level of expense to continue in the third
quarter, they are expected to decrease significantly in the fourth quarter of
this year with the closing of the transaction for the sale of dsIT's outsourcing
consulting business.

         The Company's share of Comverge's net loss of $6.1 million for the
first six months and $3.0 million for the second quarter of 2005 was $0.4
million and $0.2 million, respectively. As the carrying value of the Company's
investment in Comverge's common stock and preferred stock has been reduced to
zero, the Company will no longer be recording equity losses in Comverge.

         On July 27, 2005, the Company and the other shareholders of dsIT
entered into a definitive agreement for the sale of dsIT's outsourcing
consulting business to Taldor Computer Systems (1986) Ltd. (TASE: TALD) for
approximately $6 million in cash. The price is subject to adjustment under the
terms set forth in the agreement. The Company's net share of the purchase price
is expected to be approximately $3.5 million. The closing of the transaction is
subject to consents and approvals, including approval of various Israeli
government authorities, dsIT's banks and certain other parties.

         Mr. George Morgenstern, President and CEO of DSSI commented: "The
results in the second quarter suffered from the volatile nature of the computer
hardware market and a decrease in consulting sales, due in part to dsIT being in
flux as a result of the pending sale of this business. We are close to
completing the sale of dsIT's consulting outsourcing business. We believe our
increased focus on dsIT's project and solution business, which the company will
be retaining, will allow us to better leverage our expertise and reputation in
developing and marketing solutions in the defense, homeland security and
commercial areas."
