(the "Company"). The principal executive offices of the Company are located at
1100 Cassatt Road, Berwyn, Pennsylvania, 19312.

Item 2.  IDENTITY AND BACKGROUND.

         The Reporting  Persons filing this statement  include the Fund,  PCM,
PCM LLC and Mr. Karim Samii.  The business address of each Reporting Person is
1001 Avenue of the Americas,  Suite 1100, New York, New York 10018. PCM serves

in this Schedule 13D. PCM,  through one or more funds and/or accounts  managed
by it and/or its  affiliates,  is engaged in the investment in property of all
kinds,  including  but not  limited to  capital  stock,  depository  receipts,
investment companies,  mutual funds,  subscriptions,  warrants,  bonds, notes,
debentures,  options and other  securities and instruments of various kind and
nature.  PCM LLC, as the general  partner of PCM, and Mr. Karim Samii,  as the

Schedule 13D came from the working capital of the Fund.

         The Fund originally acquired senior subordinated notes and Shares for
investment  because the Reporting Persons believed that such securities,  when
purchased,  were  substantially  undervalued  and  represented  an  attractive
investment   opportunity.   The  Reporting   Persons  have  communicated  with
management  of the Company,  the board of directors of the Company (the "Board
of Directors") and other  stakeholders in the Company,  and expect to continue
to do so, regarding,  among other things, their desire that the Company pursue
appropriate  measures to enhance the Company's  value.  The Reporting  Persons
intend to closely evaluate the performance of the Company and the value of the
Fund's  investment in the Company,  including but not limited to the continued
analysis and  assessment by the Reporting  Persons of the Company's  business,
assets,  operations,  financial condition,  capital structure,  management and
prospects.

         In a recent  effort to more  closely  assess  the  Company's  capital
structure and financial  condition,  PCM joined an  unaffiliated  committee of
certain  holders of the Company's debt securities  (the  "Committee")  for the
purpose of entering into  discussions with the Company relating to a potential
financing restructuring of the Company. As part of these discussions, on April
17, 2006, PCM entered into a confidentiality  agreement (the  "Confidentiality
Agreement")  with the Company  which  allowed PCM and its  representatives  to
receive  non-public,  confidential,  and  proprietary  information  about  the
potential restructuring.  The Confidentiality  Agreement was terminated on May
2, 2006 and PCM was discharged of all obligations thereunder. No agreement was
reached  between  the Company and the  Committee  with  respect to a potential
restructuring.

         On May 11,  2006,  the Fund sent a letter  to the Board of  Directors
expressing its disappointment  with the outcome of the proposed  restructuring
negotiations and the Fund's concern that recent actions taken by the Company's
management  do not  adequately  address  the  financial  issues the Company is
currently facing.

         If the Reporting  Persons remain  unsatisfied with the performance of
the Company and the value of their  investment,  they may, among other things:
(i)  communicate  with other  stockholders  of the Company,  or other persons,
regarding the composition of the Board of Directors and management,  (ii) seek
to cause the Company to merge with or into,  consolidate with, transfer all or
substantially  all of its  assets  to, or  otherwise  engage  in any  business
combination or transaction (including the sale of certain assets) with, one or
more other parties,  and communicate with such other parties,  (iii) perform a
strategic  review of the Company's  operations  with a view to optimizing such
operations,  transferring  individual  assets  and/or  reducing the  Company's
currently  outstanding  debt,  (iv)  propose  to  management,   the  Board  of
Directors, or other persons, various alternatives for raising cash or reducing
the  Company's  level  of   indebtedness,   (v)  solicit  proxies  from  other
stockholders  to be used to seek the  election of one or more  nominees of the
Reporting  Persons and/or (vi) take other actions which the Reporting  Persons
believe to be appropriate.

         Except as set forth herein or as would occur upon  completion  of any
of the actions discussed herein, the Reporting Persons have no present plan or
proposal  that would  relate to or result in any of the  matters  set forth in
subparagraphs  (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons intend
to review the Fund's  investment  in the Company on a  continuing  basis.  The
Reporting Persons have in the past and may continue in the future to engage in
discussions with management, the Board of Directors, other stockholders of the
Company and other relevant parties concerning the business,  operations, board
composition,  management,  strategy and future plans of the Company. Depending
on various factors  including,  without  limitation,  the Company's  financial
position and strategic  direction,  the outcome of the discussions and actions
referenced above, actions taken by the Board of Directors, price levels of the
Shares,  other investment  opportunities  available to the Reporting  Persons,
conditions  in  the  securities  market  and  general  economic  and  industry
conditions,  the  Reporting  Persons may in the future take such  actions with
respect  to the Fund's  investment  in the  Company  as they deem  appropriate
including, without limitation, purchasing additional Shares or selling some or
all of the  Shares  held by the  Fund,  engaging  in short  selling  of or any
hedging or similar  transactions  with respect to the Shares and/or  otherwise
changing its intention with respect to any and all matters referred to in Item
4 of Schedule 13D.
