PART I. FINANCIAL INFORMATION 
 ITEM 4. CONTROLS AND PROCEDURES  (a)
    
    The Company maintains disclosure controls and procedures that are designed to
ensure that information required to be disclosed in its filings under the Securities
Exchange Act of 1934 is recorded, processed, summarized and reported within the periods
specified in the rules and forms of the Securities and Exchange Commission. Such
information is accumulated and communicated to management of the Company, including the
Chairman of the Board and Chief Executive Officer and the Vice Chairman, Chief
Financial Officer and Chief Accounting Officer (collectively the Certifying
Officers), as appropriate, to allow timely decisions regarding required disclosure.
The management of the Company, including the Certifying Officers, recognizes that any
set of controls and procedures, no matter how well designed and operated, can provide
only reasonable assurance of achieving the desired control objectives.(b)
    
    As of the end of the period covered by this Quarterly Report on Form 10-Q, the
Company has carried out an evaluation, under the supervision and with the participation
of management, including the Certifying Officers, of the effectiveness of the design
and operation of the Companys disclosure controls and procedures. Based upon that
evaluation, the Certifying Officers concluded that disclosure controls and procedures
are effective in providing reasonable assurance that the information required to be
disclosed is recorded, processed, summarized, and reported within the periods specified
by the Securities and Exchange Commission.Variable Interest Entities
The Companys consolidated financial statements for the period ended September 30, 2004,
include assets in the amount of $154.3 million, liabilities in the amount of $74.7
million and a net loss of $3.7 million related to Variable Interest Entities (VIEs).
The Companys assessment of disclosure controls and procedures, as described above,
includes the Variable Interest Entities. Each of the VIEs has a discrete number of
assets and the Company, as lender and guarantor to the VIEs, has been provided
sufficient information to conclude that the Companys procedures with respect to these
VIEs are effective in providing reasonable assurance that the information required to be
disclosed by the Company relating to these entities is reconciled, processed, summarized
and reported within the periods specified by the Securities and Exchange Commission.
However, management has been unable to assess the effectiveness of internal controls at
those entities, due to the Companys inability to dictate or modify the controls of
those entities, or to assess those controls.(c)
    
    There have been no changes in the Companys internal controls over financial
reporting identified in connection with the evaluation referred to above that occurred
during the Companys third quarter that has materially affected, or is reasonably
likely to materially affect, the Companys internal controls over financial reporting.   -4-
