      I, Joseph M. Cummins, certify that:

      1. I  have  reviewed  this  annual  report  on  Form  10-KSB  of  Amarillo
Biosciences, Inc.;

      2. Based on my  knowledge,  this annual report does not contain any untrue
statement of 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 periods  covered by this annual
report;

      3. Based on my knowledge,  the financial  statements,  and other financial
information  included  in this annual  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 annual report;

      4. I am responsible for establishing and maintaining  disclosure  controls
and  procedures  (as  defined in Exchange  Act Rules  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
subsidiaries, is made known to us by others within those entities,  particularly
during the period in which this annual report is being prepared;

            (b)  evaluated  the  effectiveness  of the  registrant's  disclosure
controls and  procedures  as of a date within 90 days of the filing date of this
annual report (the "Evaluation Date"); and

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

      5. As the registrant's  certifying officer I have disclosed,  based on the
most recent evaluation,  to the registrant's auditors and the audit committee of
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 data and have identified for
the registrant's auditors any material weaknesses 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.

      6. I have  indicated  in this  annual  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.
