I, Dr.

1. I have
reviewed this quarterly report on Form 10-Q of Dynamic Alert Limited (the
“Registrant”):





2. Based
on my knowledge, this 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;

included in this 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 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-14 and 15d-14) 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 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
      as of a date within ninety (90) days prior to the filing date of this
      quarterly report (the "Evaluation Date");
and





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





5. The
Registrant’s other certifying officer and I have disclosed, based on our most
recent evaluation, 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 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. The
Registrant’s other certifying officer and I have indicated in this 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.
