 In
        connection with the Form 10-QSB of Biomoda, Inc. for the quarter ended March
        31,
        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.
