Technologies, Inc.;

   2. Based on my knowledge, this 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 report;

as of, and for, the periods presented in this report;

   4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15(d)-15(e)) for the registrant and 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 report is being
   prepared;

         b) Evaluated the effectiveness of the registrant's disclosure
   controls and procedures and presented in this report our conclusions about

         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 of internal control over financial reporting 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 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
   control over financial reporting.
