CERTIFICATION


I, David J. Vogel,  certify  that:

1.   I have  reviewed  this annual  report on Form 10-K of Salomon  Smith Barney
     Diversified 2000 Futures 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.   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-14 and 15d-14) for the registrant and we 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 and  procedures as of a date within 90 days prior to the
               filing date of this annual report (the "Evaluation Date"); and

          c.   presented  in  this  annual  report  our  conclusions  about  the
               effectiveness of the disclosure  controls and procedures based on
               our evaluation as of the Evaluation Date;

5.   The registrant's other certifying  officers and I have disclosed,  based on
     our 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.
