                     DATA SYSTEMS & SOFTWARE INC. ANNOUNCES
                  RESULTS FOR THE YEAR ENDED DECEMBER 31, 2004

Mahwah, New Jersey - April 1, 2005 -- Data Systems & Software Inc. (OTCBB: DSSI)
today announced results for the year ended December 31, 2004.

      The results for the year ended December 31, 2004 announced today, reflect
the lower overall level of operations reported in 2004, due to the Company no
longer fully consolidating Comverge commencing the second quarter of 2003.
However, the Company continues to include Comverge's results in the Company's
consolidated results on an equity basis and Comverge has continued to account
for a majority of the Company's losses.

      The Company reported a net loss of $1.2 million for the year ended
December 31, 2004, an 81% improvement over the net loss of $6.3 million for the
year ended December 31, 2003. Sales for the year 2004 decreased to $30.1 million
from 2003 sales of $35.0 million, due almost entirely to the inclusion in 2003
of Comverge's $4.7 million of first quarter sales; commencing the second quarter
of 2003, the Company no longer consolidated Comverge's operations. Sales in the
Company's two consolidated operating segments did not change significantly.

      The decrease in gross profit, to $6.5 million in 2004 from $7.1 million in
2003, was entirely attributable to the inclusion of Comverge's gross profit of
$1.3 million in the first quarter of 2003. This decrease was partially offset by
an increase in gross profit in both of the Company's consolidated segments, as a
result of improved margins in both segments. In the software consulting and
development segment the gross profit margin increased to 23% in 2004 from 21% in
2003, and in the computer hardware sales segment gross profit margin increased
to 20% in 2004 from 17% in 2003. The consolidated gross profit margin improved,
as the improvement in the company's operating segments more than offset the
negative impact of the Company's no longer consolidating Comverge's relatively
higher margin sales.

      The decrease in selling, marketing, general and administrative expenses
("SMG&A") in 2004 as compared to 2003, was primarily attributable to the fact
that SMG&A in the 2003 period included $2.2 million of Comverge's SMG&A; since
the second quarter of 2003, the Company no longer consolidates Comverge's
operations. The remaining decrease in SMG&A was due to a decrease in SMG&A in
the Company's software consulting and development segment as well as decreased
corporate general and administrative expenses.

      The decrease in interest expense, net, was primarily attributable to
completing the accretion of discounts and the amortization of related costs in
connection with convertible debt and warrants in the first few months of 2003,
which accounted for almost one-half of these expenses in 2003. Interest expense
also decreased as a result of the continued reduction of the Company's
outstanding bank debt balance, as well as reductions in interest rates
throughout 2003 and 2004.

      The Company's share in Comverge's losses, whose results are accounted for
on an equity basis as of the second quarter of 2003, decreased to $1.2 million
in 2004 from $1.8 million in 2003. Comverge's net loss was $9.3 million and $8.0
million in 2004 and in the nine month period ended December 31, 2003,
respectively. The decrease in the Company's share of Comverge's losses was
attributable to the continued reduction in the Company's percentage of
Comverge's preferred share equity, due to dilution as a result of investments by
others and the Company's sale of a portion of its Comverge preferred shares in
September 2004 for approximately $1.0 million, resulting in a gain of $0.7
million.




      Since the Company had not recorded revenues from its US-based consulting
business since the latter part of 2003, during the second quarter of 2004, the
Company discontinued its efforts to reestablish this business as it was
previously conducted. As a result, the Company recorded a gain from discontinued
operations of $0.3 million in 2004. The Company's 2003 results were not restated
to reflect the discontinuance of this operation, as the presentation of that
year's results would not be materially different.

      George Morgenstern, Chairman, President and Chief Executive Officer of
DSSI commented: "During 2004 we continued to improve our operating results to
the point that, excluding our equity losses from Comverge, our consolidated
operations are operating at a profit. We look forward to continuing that trend.
Our Comverge affiliate continues to grow and increase its backlog, and we look
forward to seeing the impact on Comverge's bottom line results." Mr. Morgenstern
also commented on the recently announced agreement in principle to sell dsIT: "I
was extremely pleased to have been able to announce the agreement in principle
for the sale of our dsIT subsidiary to Matrix IT Ltd. We are now in the due
diligence and documentation process for the transaction and hope to close it
sometime in the second quarter of this year."

consulting and development services, and is an authorized direct seller and
