                                                                   ------------


       CERTIFICATION PURSUANT TO RULE 13a-14 OR 15d-14 OF THE SECURITIES
        EXCHANGE ACT OF 1934, AS ADOPTED PURSUANT TO SECTION 302 OF THE
                           SARBANES-OXLEY ACT OF 2002

      I, Gene C. Stahl, certify that:

1.    I have  reviewed  this current  report on Form 6-K of Precision  Drilling
      Trust;

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 issuer as of, and for, the period presented in this report;

4.    The  issuer's  other  certifying   officer  and  I  are  responsible  for
      establishing  and  maintaining  disclosure  controls and  procedures  (as
      defined in Exchange Act Rules 13a-15(e) and l5d-15(e)) for the issuer 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
           issuer, 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 issuer's  disclosure controls and
           procedures  and presented in this 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 this report any change in the issuer'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  issuer's  internal
           control over financial reporting; and

5.    The issuer's other certifying officer and I have disclosed,  based on our
      most recent evaluation of internal control over financial  reporting,  to
      the issuer's  auditors and the audit  committee of the issuer's  board of
      directors (or persons performing the equivalent function):

      (a)  All significant  deficiencies and material  weaknesses in the design
           or operation of internal control over financial  reporting which are
           reasonably  likely to  adversely  affect  the  issuer'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 issuer's internal
           control over financial reporting.
