                               AROTECH CORPORATION

                                  CERTIFICATION

I, Robert S. Ehrlich, certify that:

1.    I have reviewed this quarterly report on Form 10-Q of Arotech Corporation;

2.    Based on my knowledge,  this quarterly  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 quarterly report;

3.    Based on my  knowledge,  the  financial  statements,  and other  financial
      information  included  in this  quarterly  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
      quarterly 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 we have:

      (a)   designed such  disclosure  controls and  procedures,  or caused such
            disclosure   control  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 quarterly report is being prepared;

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

      (c)   disclosed in this  quarterly  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  first
            fiscal  quarter  in the  case of this  quarterly  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 registrant's board
      of directors (or persons performing the equivalent function):

      (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 controls over financial reporting.
