I, John Haddock, Chief Executive Officer of Radix Marine, Inc., certify that:

1.       I have reviewed this quarterly report of Form 10-QSB of Dtomi, 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 this 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.       The  registrant's  other  certifying  officer and I are 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
               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.       The registrant's other certifying  officer and 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  for
               internal  controls which could adversely  affect the registrant's
               ability to record,  process,  summarize and report financial date
               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.       The registrant's  other certifying officer and I have indicated in this
         quarterly  report  whether  or not there  were  significant  changes in
         internal  controls  or in other facts that could  significantly  affect
         internal controls subsequent to the date of our most recent evaluation,
         including any corrective action with regard to significant deficiencies
         and material weaknesses.
