         A;

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

         cash flows of the Partnership as of, and for, the periods presented in
         this quarterly report;

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

         have:

              a.  Designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed under
                  my supervision, to ensure the material information relating to
                  the Partnership, including its consolidated subsidiaries, is
                  made known to me by others within the Partnership,
                  particularly during the period in which this quarterly report
                  is being prepared;

              b.  Designed such internal control over financial reporting, or
                  caused such internal control over financial reporting to be
                  designed under my supervision, to provide reasonable assurance
                  regarding the reliability of financial reporting and the
                  preparation of financial statements for external purposes in
                  accordance with generally accepted accounting principles;

              c.  Evaluated the effectiveness of the Partnership'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

              d.  Disclosed in this report any change in the Partnership's
                  internal control over financial reporting that occurred during
                  the Partnership's most recent fiscal quarter that has
                  materially affected, or is reasonably likely to materially
                  affect, the Partnership's internal control over financial
                  reporting; and

5.       I have disclosed, based on my most recent evaluation of internal
         control over financial reporting, to the Partnership's auditors and the
         audit committee of the board of directors (or persons performing the
         equivalent function):
<PAGE>
              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
                  Partnership'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
