**CERTIFICATIONS**





I,
      Stephen A. Michael, acting President, certify that:





1.  I
      have
      reviewed this annual report on Form 10-KSB of Invisa, Inc.
      (“Invisa”);





2.  Based
      on
      my knowledge, this 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 annual
      report;





3.  Based
      on
      my knowledge, the financial statements, and other financial information included
      in this annual report, fairly present in all material respects the financial
      condition, results of operations and cash flows of Invisa as of and for, the
      periods presented in this annual report;





4.  Invisa’s
      other certifying officers 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 Invisa 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 Invisa, including its consolidated subsidiaries, is
      made
      known to us by others within those entities, particularly during the period
      in
      which this 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 Invisa’s disclosure controls and procedures and presented
      in this annual report our conclusions about the effectiveness of the disclosure
      controls and procedures based on our evaluation as of the end of the period
      covered by this report based on such evaluation; and





d.    Disclosed
      in this report any change in Invisa’s internal control over financial reporting
      that occurred during Invisa’s most recent fiscal quarter (Invisa’s fourth fiscal
      quarter in the case of an annual report) that has materially affected, or is
      reasonably likely to materially affect, Invisa’s internal control over financial
      reporting.





5.  Invisa’s
      other certifying officers and I have disclosed, based on our most recent
      evaluation of internal control over financial reporting, to Invisa’s auditors
      and the audit committee of Invisa’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 Invisa’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 Invisa’s internal control over financial reporting;
      and





6.  Invisa’s
      other certifying officers and I have indicated in this annual report whether
      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.
