          Based upon information set forth in the Company's  Quarterly Report on
Form 10-Q for the  quarterly  period ended June 30,  2005,  as of August 1, 2005
there were  15,398,693  Shares  issued and  outstanding.  On October  13,  2005,
Cerberus CH LLC, a Delaware  limited  liability  company  ("Cerberus  CH"),  and
Cerberus America Series One Holdings,  LLC, a Delaware limited liability company
("Cerberus  America," and together  with  Cerberus CH, the "Cerberus  Entities")
fully  exercised  warrants to purchase an  aggregate of  1,209,250  Shares.  The
1,209,250  Shares  received  from the  exercise of the  warrants  were used upon
receipt to cover existing short positions on October 13, 2005.  Stephen Feinberg
possesses sole power to vote and direct the disposition of all securities of the
Company held by the Cerberus  Entities.  Thus,  as of October 13, 2005,  for the
purposes of Reg. Section  240.13d-3,  Stephen Feinberg is deemed to beneficially
own no Shares.

          The only  transactions  in Shares,  or  securities  convertible  into,

entity  controlled by him or any person or entity for which he possesses  voting

entered into more than sixty days on or prior to October 13, 2005.

          Stephen  Feinberg ceased to be the beneficial owner of more than 5% of
the Shares deemed to be outstanding as of October 13, 2005.
