                  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 amended annual report on Form 10-K/A of Arotech
         Corporation;

     2.  Based on my knowledge, this amended 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 amended annual report;

     3.  Based on my knowledge, the financial statements, and other financial
         information included in this amended 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 amended 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)) and internal
         control over financial reporting (as defined in Exchange Act Rules
         13a-15(f) and 15d-15(f)) 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 amended annual report is being prepared;

     (b) designed such internal control over financial reporting, or caused such
         internal control over financial reporting to be designed under our
         supervision, to provide reasonable assurance regarding the reliability
         of financial reporting and the preparation of financial statements for
         external purposes in accordance with generally accepted accounting
         principles;

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

     (d) disclosed in this amended 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 amended 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.
