ITEM 4.   PURPOSE OF TRANSACTION

The shares of the Issuer's Common Stock, the Warrants, the Units, the Series B
Preferred Stock, the Series A Preferred Stock and the Series C Preferred Stock
described herein were acquired for investment purposes and for the purposes
described herein.  Based on continuing evaluation of the Issuer's businesses and
prospects, alternative investment opportunities and all other factors deemed
relevant in determining whether additional shares of the Issuer's Common Stock
will be acquired, additional shares of Common Stock may be acquired in the open
market or in privately negotiated transactions, or some or all of the shares of
the Issuer's Common Stock may be sold.  Because the Special Credits Limited
Partnership, the Special Credits Trust, Trust IIIb, Oaktree Account I and the
Opportunities Fund own 20.2%, 11.5%, 16.2%, 13.2% and 29.2%, respectively, of
the Issuer's Common Stock, they may be deemed, either individually or in the
aggregate, to have control of the Issuer.  Except as set forth elsewhere in this
Schedule 13D, Special Credits, the other TCW Related Entities, Oaktree, the
Oaktree Accounts and the Opportunities Fund have made no proposals and have
entered into no agreements, other than the Registration Rights Agreement by and
among the Issuer and Special Credits dated as of December 30, 1994, and amended
as of February 21, 1996, June 10, 1996, August 8, 1997 and June 5, 1998
described below in Item 6, which would be related to or would result in any of
the matters described in Items 4(a)-(j) of Schedule 13D; however, as part of
their ongoing review of investment alternatives, Special Credits, the other TCW
Related Entities, Oaktree, the Oaktree Accounts and the Opportunities Fund may
consider such matters in the future and, subject to applicable laws, may
formulate a plan with respect to such matters subject to applicable law, and,
from time to time, Special Credits, such other TCW Related Entities, the Oaktree
Accounts, the Opportunities Fund or Oaktree may hold discussions with or make
formal proposals to management or the Board of Directors of the Issuer, other
stockholders of the Issuer or other third parties regarding such matters.
