      could not be eliminated without unreasonable effort or expense;
      (b) The subject annual report, semi-annual report, transition report on
      Form 10-K, Form 20-F,11-K or Form N-SAR, or portion thereof, will be
  X   filed on or before the fifteenth calendar day following the prescribed

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 portion thereof, could not be filed within the
prescribed time period.(Attach Extra Sheets if Needed)
The Form 10-K for the Registrant could not be filed within the prescribed
timeframe without unreasonable effort or expense, because under the
Registrant's Pooling and Servicing Agreement the annual servicing report to be
provided by the independent public accountants is not due until May 31, 2003.
Registrant has not yet obtained such report and therefore is unable to
provide the appropriate certification required under Exchange Act Rule 13a-14

calendar day following the prescribed due date.
