                           unreasonable effort or expense;

PART III - NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
N-SAR, or the transition report or portion thereof, could not be filed within
the prescribed time period.

                                    POTENTIAL PERSONS WHO ARE TO RESPOND TO THE
                                    COLLECTION OF INFORMATION CONTAINED IN THIS
                                    FORM ARE NOT REQUIRED TO RESPOND UNLESS THE
                                    FORM DISPLAYS A CURRENTLY VALID OMB CONTROL
                                    NUMBER.


On July 30, 2002, the Registrant announced on its Current Report on Form 8-K
that it had changed its independent public accountants from Arthur Andersen LLP
to KPMG LLP. The Registrant changed accountants because of the well-publicized
circumstances surrounding Arthur Andersen LLP. The Registrant is unable to
prepare and file its Form 10-Q for the period ended June 30, 2002, within the
prescribed time period as a result of unforeseen delays in connection with the
selection of KPMG LLP and the related completion of the Registrant's unaudited
financial statements for such period. The Registrant cannot eliminate the
reasons for its inability to file its Form 10-Q and obtain the necessary
management review of such filing without unreasonable effort and/or incurring
unreasonable expenses. The Registrant's Form 10-Q for the period ended June 30,
2002, will be filed as soon as reasonably practicable and in no event later than
the fifth calendar day following the prescribed due date of such Form 10-Q.
