In
      connection  with the Form 10-QSB 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 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.
