I, Robert Lerner certify that:

     Fund, L.P.

2)   Based on my knowledge, this annual 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 annual report;

3)   Based on my knowledge, the financial statements, and other financial
     information included in this annual report, fairly present in all
     material respects the financial condition and results of operations
     of the registrant as of, and for, the periods presented in
     this annual report;

4)   I am responsible for establishing and maintaining disclosure controls and
     procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the
     registrant and I have:

     a)   designed such disclosure controls and procedures 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
          annual report is being prepared;

     b)   evaluated the effectiveness of the registrant's disclosure controls

          effectiveness of the disclosure controls and procedures based on
          our evaluation as of the Evaluation Date;

5)   I have disclosed, based on my most recent evaluation, to the registrant's
     auditors and the audit committee of registrant's board of directors (or
     persons performing the equivalent function);

     a)   all significant deficiencies in the design or operation of internal
          controls which could adversely affect the registrant's ability to
          record, process, summarize and report financial data and have
          identified for the registrant's auditors any material weaknesses in
          internal controls; and

     b)   any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
          controls; and

6)   The registrant's other certifying officers and I have indicated in this
     annual report whether or not 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.

     Pursuant to the requirements of the Securities Exchange Act of 1934,
this report has been signed below by the following persons on behalf of
