                      CHIEF EXECUTIVE OFFICER CERTIFICATION

                  REQUIRED BY RULES 13A-14 AND 15D-14 UNDER THE
                   SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

I, David E. Hershberg, certify that:

1.   I have reviewed this annual report on Form 10-K;

2.   Based on my knowledge, this annual 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 annual report;

3.   Based on my knowledge, the financial statements, and other financial
     information included in this annual 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 annual report;

4.   The Registrant's other certifying officers and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-14 and 15d-14) 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 annual report is being prepared;

     b)   evaluated the effectiveness of the Registrant's disclosure controls
          and procedures and presented in this annual report our conclusions
          about the effectiveness of the disclosure controls and procedures as
          of the end of the period covered by this annual report based on such
          evaluation;

     c)   disclosed in this annual 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 officers and I have disclosed, based on
     our most recent evaluation, to the registrant's auditors and the audit
     committee of Registrant's board of directors:

     a)   all significant deficiencies in the design or operation of internal
          control over financial report 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.
