Item 4.  PURPOSE OF TRANSACTION.

         This Item 4 is hereby amended by adding the following:

         "On March 22, 2006, the Fund entered into a Consent Agreement with the
Company  pursuant to which the Fund agreed to certain waivers of defaults under
the  indenture  governing the Company's  9-7/8% Senior  Subordinated  Notes due
2007,  which  defaults  resulted from the Company's  failure to timely file its
Annual Report on Form 10-K for the fiscal year ended December 31, 2005 with the
Securities  and  Exchange  Commission.  The waivers  also extend the  reporting
deadlines  for the  Company's  10-Q reports for the first quarter of 2006 until
July 10, 2006 and for the second quarter of 2006 until  September 11, 2006. The
Fund also agreed in the Consent Agreement,  subject to certain  exceptions,  to
vote unregistered Company shares received in the consent solicitation  launched
by the Company on March 27, 2006 (which  expired at 5:00 p.m. on April 7, 2006)
in favor of a transaction that may result from the Company's  strategic process
and  approved  by the  Company's  Board  of  Directors.  A copy of the  Consent
Agreement is attached hereto as Exhibit 26.

         Except as otherwise described in this Item 4 of this Schedule 13D, as
amended, the acquisition of the Shares by the Fund is for investment purposes on
behalf of the Fund."
