I,
      Cynthia A. Garr, certify
      that:





1.           
      I have reviewed this quarterly
      report on Form 10-QSB of the 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
      reporting to 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
