                  CERTIFICATION OF PRINCIPAL EXECUTIVE OFFICER
                            Section 302 Certification

I, Colm J. King, certify that:

1.   I have reviewed this annual report on Form 10-KSB of Cavit Sciences,  Inc.,
     a Florida Corporation (the "small business issuer");

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 report;

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

4.   The  small  business  issuer's  other  certifying   officer(s)  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 small business issuer 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 small
          business  issuer,  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 principals;
     c)   Evaluated the effectiveness of the small business issuer'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
     d)   Disclosed  in this  report any change in the small  business  issuer's
          internal  control over financial  reporting  that occurred  during the
          small business issuer's most recent fiscal quarter (the small business
          issuer's  fourth fiscal  quarter in the case of an annual report) that
          has materially affected, or is reasonably likely to materially affect,
          the small business issuer's internal control over financial reporting;
          and

5.   The  small  business  issuer's  other  certifying  officer(s)  and  I  have
     disclosed,  based on our most recent  evaluation  of internal  control over
     financial reporting,  to the small business issuer's auditors and the audit
     committee  of small  business  issuer'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 small  business  issuer'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 small business  issuer's
          internal control over financial reporting.
