I,
      Derek P. Downs, certify that:





1.           
I
      have reviewed this quarterly report on
      form 10-QSB of Cistera Networks, 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;





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





4.           
I
      am responsible for establishing and
      maintaining disclosure controls and procedures (as defined in Exchange Act
      Rules
      13a-15(e) and 15d-15(e)) for the small business issuer 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
      small
      business issuer, 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.           
Designed
      such disclosure control over
      financial reporting, or caused such internal control over financial reportingto be designed under our
      supervision, to provide reasonable assurance regarding the reliability of
      financial reporting and the preparation of financial statements for external
      purposes in accordance with generally accepted accounting principles;





c.           
Evaluated
      the effectiveness of the small
      business issuer'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





d.           
Disclosed
      in this report any change in
      the small business issuer’s internal control over financial reporting that
      occurred during the small business issuer’s fourth fiscal quarter that has
      materially affected, or is reasonably likely to materially affect, the small
      business issuer’s internal control over financial reporting; and





5.           
I
      have disclosed, based on my most
      recent evaluation of internal control over financial reporting, to the small
      business issuer’s auditors and the audit committee of the small issuer’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 small
      business issuer’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 small
      business issuer’s internal control over financial reporting
