                             18 U.S.C. SECTION 1350
                             AS ADOPTED PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002



I, Robert Bernstein, certify that:

1.   I  have   reviewed  this   quarterly   report  on  Form  10-Q  of  Material
Technologies, Inc..;

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.   I am 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 I have:

     a)   designed  such  disclosure  controls  and  procedures  to ensure  that
          material  information  relating  to  the  registrant,   including  its
          consolidated subsidiaries,  is made known to me 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 as of a date within 90 days prior to the filing date of
          this quarterly report (the "Evaluation Date"); and

     c)   presented  in  this  quarterly   report  my   conclusions   about  the
          effectiveness  of the disclosure  controls and procedures  based on my
          evaluation as of the Evaluation Date;

5.   I have disclosed,  based on the most recent evaluation, to the registrant's
auditors and the audit  committee  of the  registrant's  board of directors  (or
persons performing the equivalent function):

     a)   all  significant  deficiencies  in the design or operation of internal
          controls  which could  adversely  affect the  registrant's  ability to
          record,  process,   summarize  and  report  financial  data  and  have
          identified for the  registrant's  auditors any material  weaknesses in
          internal controls; 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; and

6.   I have  indicated  in this  quarterly  report  whether  or not  there  were
significant  changes  in  internal  controls  or in  other  factors  that  could
significantly affect internal controls subsequent to the date of our most recent
evaluation,   including  any  corrective  actions  with  regard  to  significant
deficiencies and material weaknesses.
