     Item 4. Purpose of Transaction

     The Reporting  Person  acquired,  on behalf of AJR,  Quest,  Cambrian Fund,
     Cambrian  Partners,  the Managed  Accounts,  the Plan and Mr. Roepers,  and
     continues to hold the Shares reported herein for investment  purposes.  The
     Reporting  Person  intends to evaluate the  performance of the Shares as an
     investment in the ordinary course of business. The Reporting Person pursues
     an investment objective that seeks capital  appreciation.  In pursuing this
     investment objective, the Reporting Person analyzes the operations, capital
     structure and markets of companies in which the Reporting  Person's clients
     invest,  including the Issuer,  on a continuous  basis through  analysis of
     documentation  and  discussions  with  knowledgeable  industry  and  market
     observers and with representatives of such companies.

     The  Reporting  Person  will  continuously  assess the  Issuer's  business,
     financial condition,  results of operations and prospects, general economic
     conditions,  the securities  markets in general and those for the Shares in
     particular,   other   developments  and  other  investment   opportunities.
     Depending on such assessments,  the Reporting Person may acquire additional
     Shares or may determine to sell or otherwise  dispose of all or some of the
     Shares presently held by AJR, Quest, Cambrian Fund, Cambrian Partners,  the
     Managed Accounts, the Plan and Mr. Roepers in the open market or in private
     transactions.   Such  actions  will  depend  upon  a  variety  of  factors,
     including,  without  limitation,  current and  anticipated  future  trading
     prices for the Shares, the financial  condition,  results of operations and
     prospects  of the Issuer,  alternative  investment  opportunities,  general
     economic,  financial market and industry  conditions and other factors that
     the Reporting  Person may deem  material to its  investment  decision.

     The Reporting Person will continue its active discussions with the Issuer's
     management  with  respect  to (i)  actions  which  might  be  taken  by the
     management  of the Issuer to maximize  shareholder  value of the Issuer and
     (ii) improving the Issuer's investor relations.  In addition, the Reporting
     Person  may hold  discussions  with  other  parties  who  might  engage  in
     shareholder  value  enhancing  activities  for  the  benefit  of all of the
     Issuer's shareholders.  There can be no assurance that the Reporting Person
     will take any of the actions described in the previous sentence.

     Except as set forth above,  the  Reporting  Person has no present  plans or
     proposals  which  relate  to or  would  result  in any of the  transactions
     required to be described in Item 4 of Schedule 13D.



     Item 5. Interest in Securities of the Issuer

     (a) Based upon the information  contained in the Issuer's  Quarterly Report

     2002.

     (b) The  Reporting  Person does not directly own any Shares.  The Reporting
     Person has entered into an investment  advisory agreement with each of AJR,
     Quest, Cambrian Fund, Cambrian Partners, the Managed Accounts and the Plan,
     pursuant  to which the  Reporting  Person  has  investment  authority  with
     respect to the securities  held by such entities or in such accounts.  Such
     power includes the power to dispose of and the power to vote the Shares. By
     reason of the  provisions of Rule 13d-3 of the  Securities  Exchange Act of
     1934, as amended, the Reporting Person is deemed to be the beneficial owner
     of the  Shares  held  by such  entities  and  accounts.  In  addition,  the
     Reporting  Person  has sole  dispositive  and  voting  power over the 1,500
     Shares beneficially owned by Mr. Roepers. Accordingly, the Reporting Person
     is  deemed  the  beneficial  owner  of  2,692,400  Shares,  or 6.71% of the
     outstanding Shares.

     (c) The following table details the  transactions by the Reporting  Person,
     on behalf of AJR,  Quest,  Cambrian Fund,  Cambrian  Partners,  the Managed
     Accounts  and the Plan,  as well as  transactions  by Mr.  Roepers,  in the
     Shares during the past sixty (60) days:

Shares during the past sixty (60) days.
