      R. Pillai, certify that:





(1)
      I

      (formerly ResCon Technology Corp.), (the "Company");





(2)
      Based
      on my knowledge, this quarterly 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 quarterly
      report;





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





(4)
      The
      Company'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 Company 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 Company, including its consolidated
      subsidiaries, is made known to us by others within those entities, particularly
      during the period in which this quarterly report is being prepared;





(b)
      Evaluated the effectiveness of the Company'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
      quarterly report based on such evaluation; and





(c)
      Disclosed in this quarterly report any change in the Company's internal controls
      over financial reporting that occurred during the Company's most recent fiscal
      quarter that has materially affected, or is reasonably likely to materially
      affect, the Company's internal controls over financial reporting;
      and





(5)
      The
      Company's other certifying officers and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to the Company's
      auditors and the audit committee of the Company's board of directors (or persons
      fulfilling the equivalent function):





(a)
      All
      significant deficiencies and material weaknesses in the design or operation
      of
      internal controls over financial reporting which are reasonably likely to
      adversely affect the Company'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 Company's internal controls over financial
      reporting.
