  I,
          Ron
          Chaimovski, certify that:
  1.  I
          have
          reviewed this Form 10-Q of Argyle Security Acquisition Corporation;
  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 report;
  3.  Based
          on
          my knowledge, the financial statements, and other financial information
          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-15(e) and 15d-15(e)) for the registrant and we 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 report is being prepared;
  (b)  Evaluated
          the effectiveness of the registrant’s disclosure controls and procedures and
          presented in this report our conclusions about the effectiveness of the
          disclosure controls and procedures, as of the end of the period covered
          by this
          report based on such evaluation; and
  (c)  Disclosed
          in this report any change in the registrant’s internal control over financial
          reporting that occurred during the registrant’s most recent fiscal quarter that
          has materially affected, or is reasonably likely to materially affect,
          the
          registrant’s internal control over financial reporting.
  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 controls 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.
