PART III--NARRATIVE

State below in  reasonable  detail why Forms 10-K,  20-F,  11-K,  10-Q,,  N-SAR,
N-CSR, or the transition report a portion or portion thereof, could not be filed
within the prescribed time period. (Attach extra Sheets if Needed)

Several days prior to the filing deadline for the registrant's  Annual Report on
Form 10-K for the fiscal year ended  December 31, 2003,  the  registrant  became
aware of an impending  lawsuit that certain  shareholders  had  expressed  their
intent to file. The lawsuit would allege various  charges of breach of fiduciary
duty and corporate  mismanagement  and request damages of at least  $10,000,000.
The  registrant  requires  additional  time to evaluate the  allegations in this
proposed  action with the  assistance  of its legal  advisors to  determine  the
appropriate  disclosure which should be made in the relevant items of Form 10-K.
In  addition,  the  registrant  requires  additional  time to  review  with  its
independent  accountants whether the proposed action will have any impact on the
financial statements and footnotes thereto to be included in the annual report.
