      Global, 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 quarterly 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 registrant as of, and for, the periods presented in
      this report;

(4)   The registrant's other certifying officer 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
      registrant and we 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
          registrant 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)  [omitted in accordance with Section III.E. of SEC Release No.
          33-8238]

     (c)  evaluated the effectiveness of the registrant'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 registrant's internal
          control over financial reporting that occurred during the
          registrant's most recent fiscal quarter that has materially
          affected, or is reasonably likely to materially affect, the
          registrant's internal control over financial reporting; and

(5)   The registrant's other certifying officer and I have disclosed, based
      on our most recent evaluation of internal control over financial
      reporting, to the registrant's auditors and the Audit Committee of the
      registrant's Board of Directors (or persons with 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 registrant'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 registrant's
          internal control over financial reporting.
