I, Tim DeHerrera, certify that:

     1.  I  have  reviewed  this  annual  report  on  Form  10-KSB/A  of Medplus
     Corporation.;
     2.  Based  on  my knowledge, this annual 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
     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  we  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 prior to 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.  I  have  disclosed,  based  on  our  most  recent  evaluation,  to  the
     registrant's  auditors  and  the  audit  committee of 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 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;  and
     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.

               Date: October 15, 2003
               /s/ Tim DeHerrera
               Tim DeHerrera
