            CERTIFICATION OF THE CHIEF EXECUTIVE OFFICER PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Peter Katevatis, certify that:

     (5)  I have reviewed this  quarterly  report on Form 10-QSB of  Mediscience
          Technology Corp.;

     (6)  Based on my  knowledge,  this  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 report;

     (7)  Based on my knowledge,  the financial statements,  and other financial
          information  included in this 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
          report;

     (8)  The registrant's  other certifying  officers and I are 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  subsidiaries,  is made
               known to us by others within those entities,  particularly during
               the period in which this 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 the report any change in the  registrant's  internal
               control over  financial  reporting  that has occurred  during the
               registrant's most recent fiscal quarter (the registrant's  fourth
               fiscal  quarter  in the  case  of the  annual  report)  that  has
               materially  affected,  or  is  reasonably  likely  to  materially
               affect,   the   registrant's   internal  control  over  financial
               reporting; and

     (9)  The registrant's other certifying officers and I have disclosed, based
          on our most recent  evaluation  of  internal  control  over  financial
          reporting, 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  control over financial  reporting  which are reasonably
               likely to 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.
