In
      connection with the Form 10-QSB of Biomoda, Inc. for the quarter ended September
      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.
