      ACT OF 2002





In
      connection  with the Form 10-QSB/A of Biomoda,  Inc. for the
      quarter ended June  30,  2007
      (the  "quarterly  report")  as
      filed  with the  Securities  and Exchange  Commission
      on the date hereof, I John J Cousins as President and Chief Financial
      Officer of the Company, certify that:





1.
       I have reviewed this  quarterly  report on Form
      10-QSB/A of Biomoda, Inc. (the "registrant");





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 his
      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 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 subsidiary 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 and presented in this quarterly 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 (the  registrant's  fourth fiscal
      quarter in the
      case of an annual report) that
      has materially affected, or is reasonably likely
      to materially affect, the registrant's internal control
      over financial reporting;








5.
      I
      have  disclosed,  based on our most
      recent  evaluation of internal  control over
      financial  reporting,  to
      the  registrant's  auditors and the  registrant's board
      of
      directors (or persons performing the equivalent functions);





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 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.
