      Officer




I, Donald T. Locke,
      certify that:




1.            
I have reviewed this
      Quarterly Report on Form 10-Q for the quarter
      ended September 30, 2005, of Summus, Inc.  (“Summus”);




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 Summus as of, and for, the
      periods presented in this report.




4.            
      Summus’s other certifying officers and I are responsible for establishing and
      maintaining disclosure controls and procedures (as defined in the Exchange
      Act
      Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting
      (as
      defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for Summus 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 Summus, 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 internal 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 Summus’ disclosure control’s 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 Summus’ internal control over financial
      reporting that occurred during Summus’ most recent fiscal quarter that has
      materially affected, or is reasonably likely to materially affect, Summus’
internal control over financial reporting; and




5.            
Summus’ other certifying officers
      and I have disclosed, based on our most recent
      evaluation of internal control over financial reporting, to Summus’ auditors and
      the audit committee of Summus’ board of directors:


(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 Summus’ 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 Summus’ internal control over financial
      reporting.
