------------------------                                 -----------------------


Item 4.   PURPOSE OF TRANSACTION.
          ----------------------

          The  Reporting  Persons  purchased  the Shares based on the  Reporting
Persons'  belief that the Shares at current  market prices are  undervalued  and
represent an attractive  investment  opportunity.  Depending upon overall market
conditions,  other investment  opportunities available to the Reporting Persons,
and the  availability  of Shares at  prices  that  would  make the  purchase  of
additional  Shares  desirable,  the  Reporting  Persons may endeavor to increase
their position in the Issuer through, among other things, the purchase of Shares
on the open market or in private transactions or otherwise, on such terms and at
such times as the Reporting Persons may deem advisable.

          No  Reporting  Person has any  present  plan or  proposal  which would
relate to or result in any of the matters set forth in  subparagraphs  (a) - (j)
of Item 4 of Schedule 13D except as set forth herein or such as would occur upon
completion of any of the actions  discussed above.  Steel Partners II intends to
review  its  investment  in the  Issuer  on a  continuing  basis  and  engage in
discussions with management and the Board of Directors of the Issuer  concerning
the business,  operations  and future plans of the Issuer.  Depending on various
factors  including,  without  limitation,  the Issuer's  financial  position and
investment  strategy,  the  price  levels  of  the  Shares,  conditions  in  the
securities markets and general economic and industry conditions,  Steel Partners
II may in the future take such  actions with  respect to its  investment  in the
Issuer as it deems  appropriate  including,  without  limitation,  seeking Board
representation,  making  proposals  to  the  Issuer  concerning  changes  to the
capitalization,  ownership  structure or  operations  of the Issuer,  purchasing
additional Shares, selling some or all of its Shares,  engaging in short selling
of or any hedging or similar  transaction with respect to the Shares or changing
its intention with respect to any and all matters referred to in Item 4.

Item 5.   INTEREST IN SECURITIES OF THE ISSUER.
          ------------------------------------

named herein is based upon  39,072,175  Shares  outstanding,  which is the total
number of Shares  outstanding  as reported in the Issuer's  Quarterly  Report on
Form 10-Q filed with the Securities and Exchange Commission on November 9, 2004.

          As of the close of business on November  17, 2004,  Steel  Partners II
beneficially  owned 2,028,000  Shares,  constituting  approximately  5.2% of the
