certify that:

1.    I have reviewed this Annual Report on Form 10-K of the Liquidating 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

4.    I am responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
Liquidating Trust 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 Liquidating Trust,
      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 Liquidating Trust'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

      internal control over financial reporting.

5.    This report discloses, based on my most recent evaluation of internal
control over financial reporting:

      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 Liquidating Trust's ability to
