     CERTIFICATION PURSUANT TO 18 U.S.C. SECTION 1350 AS ADOPTED PURSUANT TO
                 SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, John Cousins, the Chief Financial Officer of Biomoda, Inc., certify:

1.       I have reviewed this quarterly report on Form 10-QSB of Biomoda, Inc.

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 rule  13a-14 and 15d-14)
         for the registrant and have:

         a.       designed  such  disclosure  controls and  procedures 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  as of a date within 90 days prior to
                  the filing  date of this  quarterly  report  (the  "Evaluation
                  Date"); and

         c.       presented in this Quarterly  report our conclusions  about the
                  effectiveness of the disclosure  controls and procedures based
                  on our evaluation as of the Evaluation Date;

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

         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  data  and  have  identified  for  the  registrant's
                  auditors any material weakness in internal controls; and

         b.       any fraud,  whether or not material,  that involves management
                  or  other  employees  who  have  a  significant  role  in  the
                  registrant's internal controls; and

6.       I have indicated in this Quarterly  report  whether  or not 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.
