I, Daniel A. Zimmerman, certify that:

1.   I have  reviewed  this  quarterly  report  on Form 10-Q of  Electric  & Gas
     Technology, Inc.;

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 consolidated  financial  statements,  and other
     financial  information included in this quarterly report, fairly present in
     all material  respects the  consolidated  financial  condition,  results of
     operations  and cash flows of the  registrant  as of, and for,  the periods
     presented in this quarterly report;

4.   The  registrant's  other  certifying  officer  and  I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in the Exchange Act Rules 13a- 14 and 15d- 14) for the registrant and 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  quarterly
          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 quarterly report (the "Evaluation Date");

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

     d)   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  that  has  materially  affected,  or is
          reasonably  likely to materially  affect,  the  registrant's  internal
          control over financial reporting;

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 functions):

     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.
