fulfilling  their  responsibilities  to stockholders  and others relating to the
corporate  accounting and reporting practices of the Company and the quality and
integrity  of the  financial  reports of the  Company.  The Audit  Committee  is
responsible for selecting, evaluating and replacing the independent auditors and

at least three members,  all of whom must be independent and must be financially
literate.  At least one member of the Audit  Committee must have a background in
finance or accounting.  Dr. Schiff, Dr. Malley and Mr. Krause currently serve on

Audit Committee have the requisite  financial literacy and accounting or finance
background.  Mr. Krause,  who is not independent of management as defined in the
Nasdaq rules, may remain on the Audit Committee until June 14, 2001.

     The Board of Directors has also established a Compensation and Stock Option
Committee  (the  "Compensation   Committee")  which  administers  the  Company's
stock-based  compensation  plans and approves  awards of stock options and other
stock-based  compensation,  as well as reviewing and  approving  the  employment
terms and  compensation of executive  officers of the Company.  Dr. Schiff,  Dr.
Malley and Mr. Krause  currently serve on the Compensation  Committee,  with Dr.
Schiff acting as Chairman.  Ambassador Rabb serves on the Compensation Committee
as an alternate member. During 2000, the Compensation  Committee met three times
and acted by written consent four times.

was granted  options to  purchase  7,500  shares of Common  Stock at an exercise
price of $4.69 per share  (the fair  market  value of the  Common  Stock on such
date).  These options were granted  pursuant to the Company's  1994 Stock Option
Plan for Outside Directors described below.

     The  Company's  1994 Stock Option Plan for Outside  Directors  provides for
awards  of  non-qualified  options  to  directors  of the  Company  who  are not
employees  of  the  Company  or  its  affiliates  and  who  meet  certain  other
eligibility  criteria.  Pursuant  to  the  plan,  (i)  upon  first  election  or
appointment to the Board of Directors,  each newly elected eligible  director is
granted an option to purchase 7,500 shares of Common Stock and (ii)  immediately
following  each Annual  Meeting of  Stockholders  of the Company,  each eligible
director will  generally be granted an option to purchase 7,500 shares of Common
Stock.  Options granted under the plan have an exercise price per share equal to
the fair  market  value of the  Common  Stock  on the date of  issuance  and are
exercisable  beginning on the first  anniversary  of the date of the grant until
the  earliest of (i) ten years from the date of grant and (ii) one year from the
date on which an optionee ceases to be a director.  The maximum number of shares
of Common  Stock in  respect of which  awards  may be granted  under the plan is
200,000 (400,000 if the 1994 Stock Option Plan for Outside Directors is amended,
as described below), of which 177,500  non-expired  options have been granted to
date.

     In addition to serving as a director of the Company,  Mr.  Eisenberger also
serves  as an  employee  of the  Company's  Comverge  subsidiary  and  was  paid
approximately $92,000 during 2000 in connection with such employment.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The mandate of the Compensation  Committee of the Board of Directors of the
Company encompasses all matters related to compensation, including determination
of stock option and other  stock-based  compensation  and review and approval of
employment terms and compensation of executive officers. Certain matters related
to the  compensation of the Chief  Executive  Officer are also considered by the
full Board of Directors.

     The following  persons served both as members of the Board of Directors and
officers or employees of the Company in 2000:  George  Morgenstern  (Chairman of
the Board,  President and Chief Executive  Officer),  Dr. Kuhn (Vice Chairman of
the Board), Mr. Krause (Secretary) and Mr.  Eisenberger,  who is employed by the
Company's Comverge subsidiary.  During 2000, no member of the Board of Directors
who was also an officer of the Company  participated in any deliberations of the
Board of Directors or any committee  thereof relating to his own compensation or
to the  compensation  of any person to whom he is related.  Except as  described
above,  each  member  of  the  Board  of  Directors   participated  in  2000  in
deliberations   of  the  Board  of  Directors   concerning   executive   officer
compensation.  For information concerning transactions with the Company in which
directors  or  officers  may  be  deemed  to  have  an  interest,  see  "Certain
Relationships and Related Transactions" below.

EMPLOYMENT ARRANGEMENTS

     George  Morgenstern  serves as Chairman of the Board,  President  and Chief
Executive  Officer of the Company  pursuant  to an  employment  agreement  which
commenced  on  January 1, 1997 and was  amended in March 2001 to extend  through
December  31,  2002  (the  "Employment  Agreement").  The  Employment  Agreement
provides for a base salary of $420,000 per annum (currently $448,000 due to cost
of living adjustments), subject to annual review by the Board and an annual cost
of living adjustment, plus contributions to a nonqualified retirement fund equal
to 25% of his  base  salary.  Mr.  Morgenstern's  compensation  pursuant  to the
Employment Agreement also includes the use of two company  automobiles,  premium
payments on a life insurance  policy owned by Mr.  Morgenstern  and other fringe
benefits.

     Pursuant to the Employment Agreement, Mr. Morgenstern may at any time prior
to December 31, 2002,  elect to terminate  his  employment  with the Company and
thereafter  to continue to serve the Company as a  consultant  for a period (the
"Consulting  Period")  ending on December 31 of the seventh year  following  the
year in which he first commences to serve as a consultant. During the Consulting
Period,  Mr.  Morgenstern  would be entitled to receive an annual consulting fee
plus contributions to a nonqualified  retirement fund and fringe benefits on the
same  basis as  during  the  term of his  employment  as  described  above.  Mr.
Morgenstern's  annual consulting fee during the Consulting Period would be equal
to 50% of his annual salary in effect immediately prior to the Consulting Period
through the end of the fourth full calendar year of the Consulting  Period,  and
25% of such annual salary for the remainder of the Consulting Period (subject in
all cases to an annual cost of living  adjustment).  However, if Mr. Morgenstern
elects  to  become  a  consultant  following  a  breach  by the  Company  of its
obligations  under the Employment  Agreement or following a change in control of
the Company (as defined in the Employment  Agreement),  Mr. Morgenstern would be
entitled  to receive  his full  annual  salary  until  December  31,  2002,  and
thereafter  to  receive  an annual  consulting  fee as  described  above for the
balance of the Consulting  Period. The Company is obligated under the Employment
Agreement  to fund at the  beginning  of the  Consulting  Period all  amounts to
become payable to Mr.  Morgenstern for consulting  services and to fund upon his
death all  amounts  payable to his  estate.  During  the term of the  Employment
Agreement (including any Consulting Period), Mr. Morgenstern may not engage in a
business that is in substantial and direct  competition with the business of the
Company or any of its subsidiaries.

     In addition to the  compensation  provided  for  Employment  Agreement,  in
January  2000 the  Company  awarded  Mr.  Morgenstern  a bonus in the  amount of
$550,000,  at least half of which was  required to be used to reduce the balance
of his outstanding loan from the Company  discussed below under "Certain Related
Party  Transactions."  The Board  also  approved  an  additional  bonus of up to
$300,000,  $150,000 of which would have been payable only upon  completion of an
equity financing of the Company's Comverge subsidiary of at least $10 million by
December 31, 2000 (which condition was not satisfied),  and $150,000 of which is
payable only if Mr.  Morgenstern  remains  employed  full-time as President  and
Chief Executive  Officer of the Company through  December 31, 2001.  Under terms
approved by the Board,  at least  one-half of any bonus paid was  required to be
used to  reduce  any  then  outstanding  balance  of the  Company's  loan to Mr.
Morgenstern.  In  February,  the Board of  Directors  approved a purchase by the
Company  of an  aggregate  of up to  $300,000  of  the  Common  Stock  from  Mr.
Morgenstern at fair market value, provided that the proceeds from such purchases
be  applied to reduce the  balance  of his  loans.  The loans were fully  repaid
during the first  quarter of 2000 from the bonus and from the  proceeds of sales
by Mr.  Morgenstern of Common Stock to the Company on February 2, 2000 and March
2, 2000 at then current market prices.

     Yacov Kaufman serves as Vice President and Chief  Financial  Officer of the
Company and of DSI Israel pursuant to an employment  agreement entered into with
the  Company on January 1, 1999.  Although  the  employment  agreement  with Mr.
Kaufman  expired by its terms on  December  31,  2000 and has not been  formally
renewed,  the Company continues to employ Mr. Kaufman, and Mr. Kaufman

                                      -7-



continues to serve as Vice President and Chief Financial  Officer of the Company
and of DSI Israel, pursuant to the terms of such employment agreement.

     The stock option agreements with the Company's executive officers generally
provide  for  accelerated  vesting  in the event of a change in  control  of the
Company.

CERTAIN RELATED PARTY TRANSACTIONS

     During 1996 and 1997,  the Company made a loan to George  Morgenstern,  its
Chairman,  President and Chief Executive Officer.  The principal of and interest
on such loan was payable in installments as follows:  (i) 105 bi-weekly payments
of $3,000 each,  commencing  January 1998,  (ii) four annual payments of $72,000
each,  commencing  December 1998, and (iii) a final payment on December 31, 2001
in an amount equal to the then  remaining  outstanding  balance of the loan plus
accrued and unpaid  interest.  In addition,  in 1998, the Company made a loan to
Mr.  Morgenstern  in the  amount of $63,000 in  connection  with the  payment of
income tax relating to the vesting of a restricted stock award. During 2000, the
highest total aggregate  balance of loans to Mr.  Morgenstern was $511,000.  The
loans were fully repaid during the first quarter of 2000.

     During 2000,  the Company paid  approximately  $474,000 for legal  services
rendered and reimbursement of out-of-pocket  expenses to Ehrenreich  Eilenberg &
Krause LLP, a law firm in which Sheldon Krause,  a director and Secretary of the
Company,  is a member.  Such fees related to services rendered by Mr. Krause and
other members and  employees of his firm,  as well as certain  special and local
counsel retained and supervised by his firm who performed  services on behalf of
the Company.  Mr.  Krause is the  son-in-law  of George  Morgenstern,  Chairman,
President and Chief Executive Officer of the Company.

     As reported on the Summary  Compensation Table above,  Shlomie Morgenstern,
the son of George Morgenstern,  Chairman,  President and Chief Executive Officer
of the  Company,  received  compensation  during  2000 in  connection  with  his
position as Vice President--Operations.

     In March 2001, the Company retained Malley Associates  Capital  Management,
an asset  management  firm that is controlled by Susan L. Malley,  a director of
the Company,  to provide  discretionary asset management services to the Company
with respect to $2 million of the Company's funds. Investments may include fixed
income  government  and  corporate   securities,   money  market  mutual  funds,
short-term money market instruments and equity  securities.  Investments to date
have been  limited  to debt  securities  and  commercial  paper.  The  agreement
provides for a management fee of 1% per annum of the amount under management.


                  COMPENSATION REPORT OF THE BOARD OF DIRECTORS

     The goals of the Company's  compensation policy are to (i) attract,  retain
and reward  executives who  contribute to the overall  success of the Company by
offering  compensation that is competitive,  (ii) motivate executives to achieve
the Company's  business  objectives  and (iii) align the interests of executives
with the long-term  interests of stockholders.  The Board of Directors  believes
that  there  is  necessarily  an  element  of   subjectivity   in   establishing
compensation  levels for the Company's  executives and does not follow  specific
objective performance criteria when establishing such compensation levels.

     Compensation  decisions with respect to executive officers,  other than the
chief executive  officer,  have been based upon the  recommendation of the chief
executive  officer.  In 2000, the Company raised Yacov  Kaufman's base salary to
$150,000,  representing a $23,000  increase over Mr. Kaufman's 1999 base salary,
in order (i) to recognize Mr. Kaufman's  long-term service to the Company,  (ii)
to compensate him for his increased  responsibilities within the Company and DSI
Israel,  as well as in  connection  with his  duties as CFO of  Comverge,  which
represents the Company's current strategic focus and (iii) to incentivise him to
remain  with the  Company  given  his key role in the  affairs  of the  Company.
Additionally,  in 2000 the  Company  granted  Mr.  Kaufman  a  $32,000  bonus to
recognize his role in facilitating  the sale of the Company's  interest in Tower
Semiconductor Ltd.

     In 2000, Shlomie Morgenstern was appointed Vice President--Operations,  and
in  recognition  of the  increased  responsibilities  that  were part of his new
position,  the  Company  raised  Mr.  Morgenstern's

                                      -10-



base salary to $160,000.  Additionally,  in 2000 the Company  granted a $100,000
bonus to Mr.  Morgenstern to recognize Mr.  Morgenstern's role in increasing the
value of the CinNetic division of the Company's  International  Data Operations,
Inc. subsidiary, and in facilitating its sale.

     In 2000,  Frank  Magnotti's base salary was raised to $175,400,  reflecting
increased duties and  responsibilities  as Comverge expanded its activities with
the acquisition of the Scientific-Atlanta Control Systems business division.

     During 2000, George  Morgenstern,  Chairman,  President and Chief Executive
Officer of the Company,  was paid pursuant to an employment agreement previously
entered into with the Company. In addition, the Company granted a $550,000 bonus
to Mr. Morgenstern to recognize Mr.  Morgenstern's role in facilitating the sale
of the  Company's  interest  in  Tower  Semiconductor  Ltd.,  as  well as in the
Company's  acquisition  of  the  Scientific-Atlanta   Control  Systems  business
division.  At least half of the $550,000 bonus was required to be used to reduce
the balance of his  outstanding  loan from the  Company,  and the loan was fully
repaid during the first  quarter of 2000.  The Board also approved an additional
bonus of up to $300,000 (the "Additional  Bonus"),  $150,000 of which would have
been  payable  only upon  completion  of an equity  financing  of the  Company's
Comverge  subsidiary  of at least  $10  million  by  December  31,  2000  (which
condition  was  not  satisfied),  and  $150,000  of  which  is  payable  to  Mr.
Morgenstern  only if he  remains  employed  full-time  as  President  and  Chief
Executive  Officer of the Company  through  December 31,  2001.  One half of the
Additional Bonus was meant to provide Mr. Morgenstern with additional  incentive
to facilitate a Comverge financing and to reward him if successful, and one half
of the Additional Bonus is meant to provide Mr. Morgenstern with an incentive to
maintain  his  full-time  employment  with the Company and not elect  consulting
status, for which Mr. Morgenstern is eligible under his employment agreement.

     The Board  believes  that the use of stock  options  and other  stock-based
compensation to compensate  executive officers  encourages and rewards effective
management that results in long-term corporate financial success, as measured by
stock price  appreciation.  The Board further  believes that such use aligns the
interests of the Company's executives with those of the Company's  stockholders.
No new grants were made in 2000, except that 20,000 options that were previously
granted to Mr. Kaufman and 97,250 options that were previously granted to George
Morgenstern,  all of which were scheduled to expire in April 2000, were extended
on their original terms,  including exercise price, together with all options of
employees of the Company  which were expiring at the same time. In extending the
options,  the  Compensation  Committee  expressed its view that extending  these
options on their  original  terms was in  furtherance  of the Company's  overall
compensation goals.

                             AUDIT COMMITTEE REPORT

     The Audit  Committee is composed of three  directors  and operates  under a
written charter  adopted by the Board,  and included as Appendix A to this Proxy
Statement.

     Management is responsible for the Company's internal controls and financial
reporting  process.  The external  auditors are  responsible  for  performing an
independent  audit  of  the  Company's   consolidated  financial  statements  in
accordance  with  generally  accepted  auditing  standards and to issue a report
thereon.  The Audit  Committee's  responsibility is to monitor and oversee these
processes.

     In this  context,  the Audit  Committee has met and held  discussions  with
management  and the  external  auditors.  Management  represented  to the  Audit
Committee that the Company's  consolidated financial statements were prepared in
accordance  with  generally  accepted  accounting  principles,   and  the  Audit
Committee  reviewed and discussed the  consolidated  financial  statements  with
management  and the  external  auditors  prior  to  their  issuance.  The  Audit
Committee  discussed with the external auditors matters required to be discussed
by Statement on Auditing Standards No. 61 (Communication with Audit Committees).

     The Company's  external  auditors also provided to the Audit  Committee the
disclosures required by Independent Standards Board Standard No. 1 (Independence
Discussions with Audit Committees),  and the Audit Committee  discussed with the
external auditors that firm's independence.

     Based on the Audit Committee's  discussion with management and the external
auditors and the Audit  Committee's  review of the  representation of management
and  the  external  auditors  to  the  Audit  Committee,   the  Audit  Committee
recommended to the Board,  and the Board approved,  the inclusion of the audited
consolidated  financial  statements in the Company's  Annual Report on Form 10-K
for the year ended  December 31, 2000.  The Audit  Committee  and the Board have
also approved the selection of the Company's external auditors.

      COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

     Section 16(a) of the Securities  Exchange Act of 1934 (the "Exchange  Act")
requires the Company's  executive  officers and  directors,  and persons who own
more than 10% of a registered class of the Company's  equity  securities to file
reports of ownership and changes in ownership  with the  Securities and Exchange
Commission ("SEC"). These persons are also required by SEC regulation to furnish
the Company  with copies of all Section  16(a) forms they file.  Based solely on
its review of such forms received by it, or written representations from certain
reporting  persons,  the Company believes that during 2000 all applicable filing
requirements were complied with by its executive officers and directors.

                                   PROPOSAL 2

              AMENDMENT OF THE COMPANY'S 1994 STOCK INCENTIVE PLAN

     The Board of Directors of the Company has adopted,  subject to  stockholder
approval,  an amendment (the "Incentive  Plan  Amendment") to the Company's 1994
Stock Incentive Plan (the "Stock Incentive Plan"),  as amended,  authorizing the
issuance of an additional 250,000 shares under such plan, thereby increasing the
aggregate number of shares issuable under such plan from 1,350,000 to 1,600,000.

     Options to purchase  1,332,500  shares of the  Company's  Common Stock have
been granted under the Stock  Incentive  Plan,  and 500,000 of such options have
expired.  Of such  options  that have not  expired,  7,500 have been  exercised.
Additionally,  255,000  shares of  restricted  stock have been issued  under the
Stock Incentive Plan, all of which have been issued to George Morgenstern. Prior
to the adoption of the Incentive Plan Amendment,  there were only 262,500 shares
available  for  issuance  under the Stock  Incentive  Plan.  As  amended  by the
Incentive  Plan  Amendment,  subject to  stockholder  approval,  an aggregate of
512,500 shares would be available for issuance under the Stock Incentive Plan.

     The  adoption of the  Incentive  Plan  Amendment  by the Board of Directors
reflects a determination  by the Board that ensuring the continued  availability
of a sufficient  number of options available for grant under the Stock Incentive
Plan is important to the Company's ongoing and continuing efforts to attract and
retain key senior  management  personnel and align the interest of the Company's
executive officers with that of its stockholders.

     The Stock  Incentive Plan is an integral part of the Company's  stock-based
compensation  structure and has been used for grants to senior  executives.  The
825,000 unexercised,  non-expired options that have been granted under the Stock
Incentive  Plan include (i) an aggregate of 605,000  options  granted to the all
executives named in the Summary  Compensation Table under "Proposal  1--Election
of  Directors--Executive  Compensation"  at a weighted average exercise price of
$5.522 per share (440,000 to George Morgenstern to purchase shares at a weighted
average  exercise price of $6.418 per share,  130,000 to Mr. Kaufman to purchase
shares at a weighted  average  exercise price of $3.117 per share, and 35,000 to
Shlomie  Morgenstern to purchase shares at a weighted  average exercise price of
$3.196 per share),  and (ii) an aggregate of 220,000  options granted to current
members of the Board of Directors who are not executive  officers of the Company
to  purchase  shares at a weighted  average  exercise  price of $6.477 per share
(200,000 to Dr. Kuhn to purchase shares at an exercise price of $6.75 per share,
and 20,000 to Mr. Eisenberger to purchase shares at a weighted exercise price of
$3.75 per share).

     Since  the  granting  of  options  under  the  Stock   Incentive   Plan  is
discretionary,  the Company  cannot at present  determine  the number of options
that will be  granted  in the  future to any  person or group of  persons or the
terms of any future  grant.  Future  option grants and the terms thereof will be
determined by the  Compensation  Committee in  accordance  with the terms of the
Stock Incentive Plan.

     No options have been granted  under the Stock  Incentive  Plan to employees
who are not directors or executive  officers of the Company.  Options granted to
nonmanagement  employees are made under the Company's 1995 Stock Option Plan for
Nonmanagement Employees.

     Set forth below is certain information concerning the Stock Incentive Plan.
A copy of the Stock  Incentive  Plan is available  upon  written  request to the
Company.

                                      -14-



GENERAL

     AUTHORIZED  SHARES. The maximum number of shares of Common Stock in respect
of which  awards  may be granted  under the Stock  Incentive  Plan is  currently
1,350,000  (1,600,000 if the Incentive  Plan  Amendment is approved) of which no
more than 500,000 may be granted as restricted  stock or delivered in payment of
restricted  stock  units.  Shares of Common  Stock  subject  to awards  that are
forfeited,  terminated, canceled or settled without the delivery of Common Stock
will again be  available  for awards.  Also,  shares  tendered to the Company in
satisfaction  or partial  satisfaction  of the exercise  price of any award will
increase the number of shares  available  for awards  under the Stock  Incentive
Plan to the extent permitted by Rule 16b-3 under the Exchange Act.

     ELIGIBILITY.  Officers  and  employees  of the Company and its  existing or
future  subsidiaries,  as well as other individuals who perform services for the
Company,  including consultants,  who can make substantial  contributions to the
successful  performance  of the Company are eligible to participate in the Stock
Incentive plan.

     ADMINISTRATION.   The  Stock   Incentive  Plan  is   administered   by  the
Compensation Committee. No person eligible to participate in the Stock Incentive
Plan may serve on the Compensation Committee.

     The Stock  Incentive  Plan may be amended or  terminated at any time by the
Board of  Directors,  except that no amendment  may be made without  stockholder
approval  if  the  Compensation  Committee  determines  that  such  approval  is
necessary  to  comply  with any tax or  regulatory  requirement  (including  any
approval  requirement  which is a prerequisite for exemptive relief from Section
16 of the Exchange Act) with which the Compensation Committee determines that it
is desirable to comply.

     AWARDS. The Stock Incentive Plan gives the Compensation Committee authority
to  grant  stock  options  and  other   stock-based   awards,   including  stock
appreciation   rights,   restricted   stock  and  restricted  stock  units,  and
performance  awards.  To date,  only stock option  grants and  restricted  stock
awards have been made under the plan.

     STOCK OPTIONS.  Stock options may be granted under the Stock Incentive Plan
at the discretion of the Compensation Committee.  Options granted under the plan
may be either incentive stock options, as defined in Section 422 of the Internal
Revenue Code of 1986, as amended (the  "Code"),  or options which do not qualify
as incentive stock options ("nonqualified stock options"). The exercise price of
a  nonqualified  stock option granted under the plan may not be less than 85% of
the fair market  value of the Common Stock on the date of grant and the exercise
price of an incentive  stock option  granted under the plan may not be less than
100% of the fair market value of the Common Stock on the date of grant.  Subject
to the foregoing,  the Compensation Committee has discretion to fix the exercise
price of such options.  The Compensation  Committee also has broad discretion as
to the terms and conditions upon which options shall be exercisable.

     The  exercise  price  of  options  may be  satisfied  in  cash  or,  in the
discretion of the Compensation  Committee,  by exchanging shares of Common Stock
owned by the optionee,  or by a combination  of cash and shares of Common Stock.
The ability to pay the option  exercise price in shares of Common Sock would, if
permitted  by the  Compensation  Committee,  enable an  optionee  to engage in a
series of  successive  stock-for-stock  exercises of an option and thereby fully
exercise an option with little or no cash investment.

     In the event that a participant is permitted to and does exercise an option
granted under the Stock Incentive Plan by delivering shares of Common Stock, the
Compensation Committee is authorized to grant or provide for the automatic grant
of Restoration  Option to such  optionee,  subject to the  satisfaction  of such
conditions or criteria as the  Compensation  Committee shall establish from time
to time. A Restoration Option shall entitle the participant to purchase a number
of shares of Common  Stock  equal to the number of such  shares  surrendered  in
payment of the exercise  price of the original  option,  at a per share exercise
price  equal to not less  than 100% of the per share  fair  market  value of the
Common  Stock

                                      -15-



on the date of grant of such Restoration Option.  Restoration Options shall have
a term not  longer  than the term  remaining  on the  original  option and shall
contain such other terms and  conditions  as the  Compensation  Committee  shall
determine.

     STOCK  APPRECIATION  RIGHTS.  Stock  appreciation  rights may be granted in
conjunction  with  or  unrelated  to  options  and,  if in  conjunction  with an
outstanding  option,  may be  granted  at the  time  of  such  option  grant  or
thereafter,  at the exercise  price of the option.  Upon the exercise of a stock
appreciation  right with respect to a share of Common Stock, a participant would
be entitled  to receive  the excess of the fair market  value of such share over
the  exercise  price  of such  right.  No  stock  appreciation  right  shall  be
exercisable  for six months  after grant.  The  Compensation  Committee  has the
authority to determine whether the value of a stock  appreciation  right is paid
in cash or shares of Common Stock or a combination of both.

     PERFORMANCE AWARDS. The Compensation  Committee also has discretion to make
contingent  grants  of  performance  awards  which  are  earned  to  the  extent
performance goals established by the Compensation  Committee are achieved over a
period of time specified by the Compensation Committee. The value of performance
awards that are earned may, in the discretion of the Compensation  Committee, be
paid in the form of cash, shares of Common Stock, or a combination of both.

     RESTRICTED  STOCK.  Awards of restricted  stock or  restricted  stock units
under the Stock Incentive Plan may be made at the discretion of the Compensation
Committee.  Such awards may consist of (i) shares of Common  Stock or (ii) units
the value of which is equal to a share of  Common  Stock.  Restricted  stock and
restricted stock units may be granted to a participant subject to forfeiture and
restrictions  on  transfer.  In  general,  a  participant  who has been  granted
restricted  stock will from the date of grant have the  benefits of ownership in
respect of such shares,  including  the right to vote such shares and to receive
dividends and other distributions thereon, subject to the restrictions set forth
in the  plan  and  in the  instrument  evidencing  such  award.  The  shares  of
restricted stock may not be sold, assigned,  transferred,  pledged, or otherwise
encumbered until the restrictions  have lapsed.  The Compensation  Committee has
authority to determine the duration of the restricted  period and the conditions
under which  restricted  stock and restricted  stock units may be forfeited,  as
well as other terms and conditions of such awards. Restricted stock units may be
paid, in the  discretion  of the  Compensation  Committee,  in cash or shares of
Common Stock or a combination  of both upon the  termination  of the  applicable
restriction period.

     TERM OF PLAN. No award may be granted under the Stock  Incentive Plan after
December  31,  2004,  except for  Restoration  Options  which may continue to be
granted as long as options under the Stock Incentive Plan are outstanding.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF OPTION GRANTS AND EXERCISES

     When an optionee  exercises a  nonqualified  stock option,  the  difference
between the option  price and higher  fair market  value of the shares of Common
Stock,  generally  on the  date of  exercise,  will be  ordinary  income  to the
optionee and  generally  will be allowed as a deduction  for federal  income tax
purposes  to  the  employer.  Any  gain  or  loss  realized  by an  optionee  on
disposition of the Common Stock  acquired upon exercise of a nonqualified  stock
option  generally  will be capital gain or loss to such  optionee,  long-term or
short-term  depending  on  the  holding  period,  and  will  not  result  in any
additional tax consequences to the employer.  The optionee's basis in the shares
for determining gain or loss on the disposition will be the fair market value of
such shares determined generally at the time of exercise.

     When an optionee  exercises an incentive stock option while employed by the
Company or a subsidiary or within three months (one year for  disability)  after
termination of employment, no ordinary income will be recognized by the optionee
at that time,  but the excess (if any) of the fair market value of the shares of
Common Stock acquired upon such exercise over the option  exercise price will be
an adjustment to taxable income for purposes of the federal  alternative minimum
tax  applicable  to

                                      -16-



individuals.  If the  shares of  Common  Stock  acquired  upon  exercise  of the
incentive  stock option are not disposed of prior to the  expiration of one year
after the date of  acquisition  and two years after the date of the option,  the
excess (if any) of the sales proceeds over the aggregate  option  exercise price
of such shares will be long-term  capital  gain,  but the  employer  will not be
entitled  to any tax  deduction  with  respect to such gain.  Generally,  if the
shares of Common Stock are disposed of prior to the  expiration  of such periods
(a  "disqualifying  disposition"),  the excess of the fair market  value of such
shares at the time of exercise over the aggregate option exercise price (but not
more than the gain on the  disposition  if the  disposition  is a transaction on
which a loss, if realized,  would be recognized)  will be ordinary income at the
time of such  disqualifying  disposition  (and the  employer  will  generally be
entitled to a federal income tax deduction in a like amount).  Any gain realized
by the optionee as the result of a  disqualifying  disposition  that exceeds the
amount  treated as  ordinary  income  will be capital  in nature,  long-term  or
short-term  depending on the holding  period.  If an  incentive  stock option is
exercised more than three months (one year for disability)  after termination of
employment,   the  tax   consequences  are  the  same  as  described  above  for
nonqualified  stock  options.  To date,  no  incentive  stock  options have been
granted under the Stock Incentive Plan.

     The foregoing discussion  summarizes the federal income tax consequences of
the grant and exercise of stock options under the Stock  Incentive Plan based on
current  provisions  of the Code which are subject to change.  This summary does
not  cover any state or local tax  consequences  of  participation  in the Stock
Incentive Plan.

     THE BOARD OF DIRECTORS  RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE STOCK
INCENTIVE  AMENDMENT  (DESIGNATED  AS  PROPOSAL 2 ON THE  ENCLOSED  PROXY  CARD)
INCREASING  THE NUMBER OF SHARES  AUTHORIZED  FOR ISSUANCE  UNDER THE 1994 STOCK
INCENTIVE PLAN BY 250,000 FROM 1,350,000 TO 1,600,000.

                                      -17-



                                   PROPOSAL 3

                AMENDMENT OF THE COMPANY'S 1994 STOCK OPTION PLAN

                              FOR OUTSIDE DIRECTORS

     The Board of Directors of the Company has adopted,  subject to  stockholder
approval,  an amendment (the "Outside Director Plan Amendment") to the Company's
1994 Stock Option Plan for Outside Directors,  as amended (the "Outside Director
Plan"),  increasing the aggregate number of shares issuable under such plan from
200,000 to 400,000 and  extending  the date until  which  options may be granted
under the Outside  Director  Plan to December  2008.  The Outside  Director Plan
Amendment  reflects the belief of the Board of  Directors  that  increasing  the
proprietary  and vested  interest of  non-employee  directors  in the growth and
performance of the Company will benefit the Company and its stockholders by more
strongly aligning the interests of such directors with those of stockholders.

     Since the inception of the Outside  Director  Plan, an aggregate of 197,500
options have been granted to non-employee directors,  and 20,000 of such options
have lapsed.  Of those  options that have not lapsed,  a total of 5,000  options
granted  under the  Outside  Director  Plan have  been  exercised.  Prior to the
adoption of the Outside  Director Plan Amendment,  there were only 22,500 shares
available for issuance under the Outside Director Plan.

     The 172,500 currently  outstanding options that have been granted under the
Outside Director Plan have exercise prices ranging from $2.44 to $11.125, with a
weighted average exercise price of $5.792 per share (including 50,000 to each of
Dr. Schiff,  Mr. Krause and Ambassador Rabb at a weighted average exercise price
of $5.963 per share,  and 22,500 to Dr.  Malley at a weighted  average  exercise
price of $4.648 per Share).  Mr.  Morgenstern,  Dr. Kuhn and Mr. Eisenberger are
not eligible to participate in the Outside Director Plan.

     Set forth below is certain  information  concerning  the  Outside  Director
Plan. A copy of the Outside Director Plan is available upon written request from
the Company.

GENERAL

     The Outside Director Plan provides for awards of nonqualified stock options
to  directors  of the  Company  who  are not  employees  of the  Company  or its
affiliates  and  who  have  not,  within  one  year  immediately  preceding  the
determination of such director's eligibility, received any award under any other
plan of the Company or its affiliates that entitles the participants  therein to
acquire stock, stock options or stock appreciation  rights of the Company or its
affiliates  ("Eligible  Directors").  The  options  granted  under  the plan are
exercisable in whole or in part at all times during the period  beginning on the
first  anniversary  of the date of grant until the earliest of (i) 10 years from
the date of grant optionee and (ii) 90 days after the date an optionee ceases to
be a director.  The  exercise  price per share of Common Stock is required to be
100% of the fair market value per share on the date the option is granted.

     Pursuant to the terms of the  Outside  Director  Plan,  options are granted
under  the  Outside  Director  Plan as  follows:  (i)  upon  first  election  or
appointment to the Board, each newly elected or appointed Eligible Director will
be granted an option to purchase 7,500 Shares;  and (ii)  immediately  following
each  annual  meeting of  stockholders  each  Eligible  Director,  other than an
Eligible  Director  first elected to the Board within the 12 months  immediately
preceding  and  including  such  meeting,  will be granted an option to purchase
7,500 Shares as of the date of such meeting.

     The maximum  number of shares of Common  Stock in respect of which  options
may be  granted  under the  Outside  Director  Plan is 200,000  (400,000  if the
Outside Director Plan Amendment is

                                      -18-



approved).  Shares  of  Common  Stock  subject  to  awards  that are  forfeited,
terminated, canceled, or settled without the delivery of Common Stock will again
be available for awards. Also, shares tendered to the Company in satisfaction or
partial  satisfaction  of the  exercise  price of any option will  increase  the
number of shares  available  for  awards to the extent  permitted  by Rule 16b-3
under the Exchange Act. No option may be granted under the Outside Director Plan
after December 31, 2008.

     The  Outside  Director  Plan may be amended by the Board,  as it shall deem
advisable  or to  conform  to any  change  in any law or  regulation  applicable
thereto,  except that the Board may not, without the  authorization and approval
of stockholders:  (i) increase the number of shares of Common Stock which may be
purchased  pursuant to options,  either  individually or in the aggregate,  (ii)
change the requirement  that option grants be priced at fair market value,  (ii)
modify in any respect the class of individuals who constitute Eligible Directors
or (iv) materially increase benefits.

     The exercise price of options may be satisfied in cash or, unless otherwise
determined  by the Board,  by  exchanging  shares of Common  Stock  owned by the
optionee, or by a combination of cash and shares of Common Stock. The ability to
pay the option exercise price in shares of Common Stock would enable an optionee
to engage in a series of successive  stock-for-stock  exercises of an option and
thereby fully exercise an option with little or no cash investment.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OUTSIDE DIRECTOR PLAN

     When an optionee  exercises an option,  the  difference  between the option
price and any higher fair market value of the shares of Common Stock,  generally
on the date of exercise,  will be ordinary  income to the optionee and generally
will be allowed as a deduction  for federal  income tax purposes to the Company.
Any gain or loss  realized  by an optionee on  disposition  of the Common  Stock
acquired  upon exercise of an option  generally  will be capital gain or loss to
such optionee, long-term or short-term depending on the holding period, and will
not result in any additional  tax  consequences  to the Company.  The optionee's
basis  in the  shares  for  determining  gain or loss  on the  disposition  will
generally  be the fair market  value of such fares  determined  generally at the
time of exercise.

     The foregoing discussion  summarizes the federal income tax consequences of
the  Outside  Director  Plan based on current  provisions  of the Code which are
subject  to  change.  This  summary  does not  cover  any  state  or  local  tax
consequences of participation in the Outside Director Plan.

     THE BOARD OF DIRECTORS  RECOMMENDS THAT THE STOCKHOLDERS  VOTE FOR APPROVAL
OF THE OUTSIDE DIRECTOR PLAN AMENDMENT (DESIGNATED AS PROPOSAL 3 ON THE ENCLOSED
PROXY CARD)  INCREASING THE AGGREGATE  NUMBER OF SHARES  ISSUABLE UNDER THE 1994
STOCK OPTION PLAN FOR OUTSIDE  DIRECTORS  FROM 200,000 TO 400,000 AND  EXTENDING
THE DATE UNTIL WHICH OPTIONS MAY BE GRANTED  UNDER THE OUTSIDE  DIRECTOR PLAN TO
DECEMBER 2008.

                   INDEPENDENT PUBLIC ACCOUNTANTS AND AUDITORS

CHANGE IN ACCOUNTANT

     On  December  1, 2000,  a  representative  of Deloitte & Touche LLP ("D&T")
notified  the  Company  that it did not wish to  stand  for  re-election  as the
independent  accountant  for  the  Company  for  the  2000  fiscal  year  audit.
Thereafter,  the Company retained KPMG LLP ("KPMG") as its independent certified
public accountants and auditors.

     D&T audited the Company's financial statements for the years ended December
31, 1998 and December 31, 1999, and provided  reviews  relating to the Company's
quarterly reports on Form 10-Q for the first three quarters of 2000. The reports
of D&T on the Company's  financial  statements for the past two fiscal years did
not contain an adverse opinion or disclaimer of opinion,  and were not qualified
or modified as to uncertainty, audit scope or accounting principles.

     During the two most recent fiscal years and through December 1, 2000, there
were no disagreements between the Company and D&T as to any matter of accounting
principles  or  practices,  financial  statement  disclosure,  or audit scope or
procedure, which disagreement, if not resolved to the satisfaction of D&T, would
have caused it to make  reference to the subject matter of the  disagreement  in
their reports on the financial statements for such periods within the meaning of
Item  304(a)(1)(iv)  of Regulation  S-K. During the two most recent fiscal years
and through December 1, 2000, no reportable  events occurred (as defined in item
304(a)(1)(v) of Regulation S-K).

     KPMG served as the Company's  independent  certified public accountants and
auditors  for the year ended  December 31,  2000,  and has been  selected as its
auditors for fiscal year 2001. A representative  of KPMG has been invited to and
is expected to be present at the Annual Meeting.  The decision to engage KPMG as
the  independent  accountants of the Company was approved by the Audit Committee
of the Company's Board.

AUDIT FEES

     The  aggregate  fees  billed  by KPMG  and D&T  for  professional  services
rendered for the audit of the Company's annual financial statements for the year
ended  December 31, 2000 and the reviews of the  Company's  quarterly  financial
statements for that fiscal year totaled $159,500, and were billed to the Company
as follows:  $135,500 by KPMG (for  services  rendered  in  connection  with the
annual  financial  statements as well as services related to the presentation of
fiscal  information  from prior fiscal years in the Company's  annual  financial
statements for the fiscal year ended December 31, 2000); and $24,000 by D&T (for
services  rendered  in  connection  with the review of the  quarterly  financial
statements for the first three quarters of 2000).

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

     The  Company  did not  engage  D&T or KPMG to  provide  systems  design and
implementation  services (as defined in  paragraph  (c) (4) (ii) of Rule 2-01 of
Regulation S-X under the Exchange Act) during the year ended December 31, 2000.

ALL OTHER FEES

     The aggregate  fees billed by KPMG for the year ended December 31, 2000 for
non-audit  services,  primarily  fees  relating to the  Company's  SEC  filings,
totaled  $69,000.

                                      -20-



     The Audit  Committee of the  Company's  Board of Directors  has  considered
whether  provision  of the services  covered  under the caption "All Other Fees"
above is compatible with maintaining KPMG's independence, and has concluded that
the provision of such services was compatible  with KPMG's  independence  as the
Company's auditors.

                STOCKHOLDER PROPOSALS FOR THE 2001 ANNUAL MEETING

     Stockholders  may present  proposals for  inclusion in the  Company's  2002

such proposals are received by the Company in writing at its principal executive
offices no later than February 21, 2002.

     Pursuant to the By-laws of the Company,  stockholders  who wish to nominate
any person for election to the Board of  Directors  or bring any other  business

at its principal  executive  offices not less than 60 days nor more than 90 days
before  the  date  of the  meeting.  A copy of the  By-laws  of the  Company  is
available upon request from the Secretary of the Company,  200 Route 17, Mahwah,
New Jersey 07430.

                                  OTHER MATTERS

     The Board of Directors of the Company does not know of any other matters to
be  presented  for action at the Annual  Meeting  other than those listed in the
accompanying Notice of Annual Meeting and described herein. If any other matters
not  described  herein should  properly come before the meeting for  stockholder

Directors' recommendations.

not a part of the proxy soliciting material.

                             SOLICITATION OF PROXIES

     The cost of soliciting  proxies for the Annual Meeting will be borne by the
Company.  In addition to use of the mails,  proxies may be solicited by personal

                          DATA SYSTEMS & SOFTWARE INC.

                                     CHARTER
                                     OF THE
                    AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

PURPOSE

The primary  purpose of the Audit  Committee (the  "Committee") is to assist the
Board of Directors  (the "Board") in fulfilling  its  responsibility  to oversee
management's conduct of the Company's financial reporting process,  including by
overviewing the financial  reports and other financial  information  provided by
the Company to any  governmental  or regulatory  body, the public or other users
thereof,  the Company's systems of internal  accounting and financial  controls,
and the annual independent audit of the Company's financial statements.

In discharging its oversight role, the Committee is empowered to investigate any
matter  brought  to its  attention  with  full  access  to all  books,  records,
facilities and personnel of the Company and the power to retain outside counsel,
auditors or other experts for this  purpose.  The Board and the Committee are in
place to represent the Company's shareholders;  accordingly, the outside auditor
is ultimately accountable to the Board and the Committee.

The Committee shall review the adequacy of this Charter on an annual basis.

MEMBERSHIP

The  Committee  shall be comprised of not less than three  members of the Board,
and  the  Committee's  composition  will  meet  the  requirements  of the  Audit
Committee Policy of the Nasdaq Stock Market, Inc.

Accordingly, all of the members will be directors:

1.   Who  have no  relationship  to the  Company  that  may  interfere  with the
     exercise of their  independence from management and the Company;  PROVIDED,
     HOWEVER,  that Sheldon Krause may continue to serve on the Committee  until
     June 14, 2001; and

2.   Who are financially  literate or who become  financially  literate within a
     reasonable period of time after appointment to the Committee.  In addition,
     at least  one  member of the  Committee  will have  accounting  or  related
     financial management expertise.

KEY RESPONSIBILITIES

The  Committee's  job is one of oversight and it  recognizes  that the Company's
management is responsible for preparing the Company's  financial  statements and
that  the  outside   auditors  are  responsible  for  auditing  those  financial
statements. Additionally, the Committee recognizes that financial management, as
well as the  outside  auditors,  have more  time,  knowledge  and more  detailed
information on the Company than do Committee members;  consequently, in carrying
out its oversight responsibilities, the Committee is not providing any expert or
special assurance as to the Company's  financial  statements or any professional
certification as to the outside auditor's work.




The  following  functions  shall  be  the  common  recurring  activities  of the
Committee in carrying out its oversight function.  These functions are set forth
as a guide with the understanding that the Committee may diverge from this guide
as appropriate given the circumstances.

o    The Committee  shall review with  management  and the outside  auditors the
     audited financial  statements to be included in the Company's Annual Report
     on Form 10-K (or the Annual Report to Shareholders if distributed  prior to
     the filing of Form 10-K) and review and consider with the outside  auditors
     the matters  required to be discussed  by  Statement of Auditing  Standards
     ("SAS") No. 61.

o    As a whole, or through the Committee chair, the Committee shall review with
     the outside auditors the Company's interim financial results to be included
     in the Company's quarterly reports to be filed with Securities and Exchange
     Commission  and the  matters  required  to be  discussed  by SAS No. 61; if
     possible,  this review  should occur prior to the  Company's  filing of the
     Form 10-Q.

o    The Committee  shall discuss with  management and the outside  auditors the
     quality and adequacy of the Company's internal controls.

o    The Committee shall:

     o    request from the outside auditors annually, a formal written statement
          delineating  all  relationships  between  the  auditor and the Company
          consistent with Independence Standards Board Standard Number 1;

     o    discuss with the outside auditors any such disclosed relationships and
          their impact on the outside auditor's independence; and

     o    recommend  that the  Board  take  appropriate  action to  oversee  the
          independence of the outside auditor.

The Committee,  subject to any action that may be taken by the full Board, shall
have the ultimate  authority and  responsibility to select,  evaluate and, where
appropriate, replace the outside auditor.
