                  CERTIFICATION OF PRINCIPAL EXECUTIVE OFFICER
            PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Robert S. Ehrlich, certify that:

     1.  I have reviewed this annual report on Form 10-K of Arotech Corporation;

     2.  Based on my  knowledge,  this annual report does not contain any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances  under which
         such  statements  were made, not misleading  with respect to the period
         covered by this annual report;

     3.  Based on my knowledge,  the financial  statements,  and other financial
         information  included  in this  annual  report,  fairly  present in all
         material  respects the financial  condition,  results of operations and
         cash flows of the  registrant as of, and for, the periods  presented in
         this annual report;

     4.  The  registrant's  other  certifying  officer and I are responsible for
         establishing  and  maintaining  disclosure  controls and procedures (as
         defined  in  Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  for  the
         registrant and have:

     (a) designed  such  disclosure  controls  and  procedures,  or caused  such
         disclosure   controls  and   procedures   to  be  designed   under  our
         supervision,  to  ensure  that  material  information  relating  to the
         registrant,  including its consolidated subsidiaries,  is made known to
         us by others within those entities,  particularly  during the period in
         which this annual report is being prepared;

     (b) evaluated the effectiveness of the registrant's disclosure controls and
         procedures  and presented in this annual report our  conclusions  about
         the  effectiveness of the disclosure  controls and procedures as of the
         end of  the  period  covered  by  this  annual  report  based  on  such
         evaluation (the "Evaluation Date"); and

     (c) disclosed in this annual report any change in the registrant's internal
         control over financial  reporting that occurred during the registrant's
         most recent fiscal quarter (the  registrant's  fourth fiscal quarter in
         the case of this annual  report) that has  materially  affected,  or is
         reasonably  likely to  materially  affect,  the  registrant's  internal
         control over financial reporting; and

     5.  The registrant's other certifying  officer and I have disclosed,  based
         on our most  recent  evaluation  of  internal  control  over  financial
         reporting,  to the registrant's auditors and the audit committee of the
         registrant's  board of directors (or persons  performing the equivalent
         functions):

     (a) all significant  deficiencies and material  weaknesses in the design or
         operation  of  internal  control  over  financial  reporting  which are
         reasonably  likely to  adversely  affect  the  registrant's  ability to
         record, process, summarize and report financial information; and

     (b) any fraud,  whether or not material,  that involves management or other
         employees  who have a  significant  role in the  registrant's  internal
         control over financial reporting.
