      reviewed this annual report on Form 10-KSB of Xedar
      Corporation;





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

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.             The
      small business issuer’s other certifying officers and I are 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) Omitted;




(c) Evaluated
      the effectiveness of the small business issuer’s disclosure controls and

(d) Disclosed
      in this report any changes in the small business issuer’s internal control over
      financial reporting that occurred during the small business issuer’s most recent
      fiscal quarter (the small business issuer’s fourth fiscal quarter in the case of
      an annual report) that has materially affected, or is reasonably likely to
      materially affect, the small business issuer’s internal control over financial
      reporting; and




5.             The
      small business issuer’s other certifying officers and I have disclosed, based on
      our most recent evaluation of internal controls over financial reporting, to
      the
      small business issuer’s auditors and the audit committee of the small business
      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.
