I, Peter Katevatis, Chairman and Chief Executive Officer of the registrant,
certify that:

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


(2)   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;


(3)   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;


(4)   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)  [paragraph omitted pursuant to SEC Release Nos. 33-8238 and
                34-47986]

           (c)  evaluated the effectiveness of the registrant's disclosure
                controls and procedures and presented in the 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

           (d)  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; and


(5)   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 registrant's board
      of directors (or persons performing the equivalent functions):

           (a)  all significant deficiencies and material weaknesses in the
                design or operation of internal controls over financial
                reporting which are reasonably likely to adversely affect the
                registrant's ability to record, process, summarize and report
                financial information.

           (b)  any fraud, whether or not material, that involves management or
                other employees who have a

                                      -18-

          significant role in the registrant's internal controls over financial
          reporting.


(6)   The registrant's other certifying officers and I have indicated in this
      quarterly report whether 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.
