Item 4: Changes in Registrant's Certifying Accountant

      On May 9, 2001, the Registrant dismissed Grant Thornton LLP as its
      independent accountants. The reports of Grant Thornton LLP for the years
      ended December 31, 2000 and December 31, 1999 did not contain an adverse
      opinion or disclaimer of opinion and were not qualified or modified as to
      uncertainty, audit scope or accounting principles. The 2000 report did
      contain an explanatory paragraph to the Registrant's ability to continue
      as a going concern.

      The decision to change accountants was recommended and approved by the
      audit committee of the Registrant's board of directors.

      During 2000 and 1999, and during the period from January 1, 2001 to May 9,
      2001, there were no disagreements with Grant Thornton LLP on accounting
      principles or practices, financial statement disclosures, or auditing
      scope or procedure which, if not resolved to the satisfaction of Grant
      Thornton LLP, would have caused Grant Thornton LLP to make reference to
      the subject matter of the disagreement in connection with their report.

      Also on May 7, 2001, the Registrant engaged J.H. Cohn LLP as its new
      independent accountants. During the two most recent fiscal years and the
      subsequent interim period preceding the engagement of J.H. Cohn LLP,
      neither the Registrant, nor anyone on its behalf, has consulted J.H. Cohn
      LLP regarding: (i) the application of accounting principles to a specific
      completed or proposed transaction, or the type of audit opinion that might
      be rendered on the Registrant's financial statements, which consultation
      resulted in the providing of a written report or oral advice concerning
      the same to the Registrant that J.H. Cohn LLP concluded was an important
      factor considered by the Registrant in reaching a decision as to the
      accounting, auditing or financial reporting issue; or (ii) any matter that
      was either the subject of a disagreement (as defined in Rule 304(a)(1)(iv)
      of Regulation S-B promulgated under the Securities Act of 1933, as
      amended) or a reportable event (as defined in Rule 304(a)(1)(v) of
      Regulation S-B).
