                            CERTIFICATION PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, James Mandel, Chief Executive Officer of Multiband Corporation, certify that:

1.    I have reviewed this annual report on Form 10-K of Multiband Corporation;

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 quarterly report;

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

4.    The  registrant's  other  certifying  officer  and  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 we
      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 registrant,  including
      its consolidated subsidiaries,  is made known to us by others within those
      entities, particularly during the period in which this quarterly report is
      being prepared;

      b) Evaluated the effectiveness of the registrant'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  registrant'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  registrant's  internal  control  over
      financial reporting; and

5.    The registrant's other certifying  officer 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 and material  weaknesses in the design or
      operation  of  internal   control  over  financial   reporting  which  are
      reasonably likely to adversely affect the registrant'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  registrant's  internal
      controls; and

6.    The  registrant's  other  certifying  officer 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.
