Item 4.   Purpose of Transaction.
          ----------------------

          Item 4 is hereby  amended by deleting  Item 4 in its  entirety  and by
substituting the following in lieu thereof:

          The Partnerships purchased the Shares because OPP, as their investment
adviser,  believed the Shares to be  undervalued.  OPP believes that the Company
has  available  to it a number of  strategic  initiatives  that will enhance its
value,  and has  engaged in  discussions  with the Board and  management  of the
Company to review these initiatives.

          On January 31, 2008 the Filing Parties  entered into an agreement (the
"Agreement") with the Company pursuant to which, among other things, the Company
agreed  to  nominate  Clifford  Press for  election  to the  Company's  Board of
Directors at the  Company's  annual  meeting  currently  scheduled for March 19,
2008,  and to elect him to the Board of  Directors  within two days in the event
that the annual  meeting is not held on or before  that date.  In the event that
the Filing Parties cease to hold  beneficially  at least 50% of the common stock
of the Company that the Filing Parties  currently hold as a group, Mr. Press has
agreed to offer to resign as a director. In addition, pursuant to the Agreement,
the Filing Parties agreed to certain  standstill  provisions  that restrict them
from, among other things,  (i) commencing any tender offer or exchange offer for
any of the Company's securities, (ii) submitting or encouraging any other person
or group to submit  nominations for director for election to the Company's Board
of Directors, (iii) submitting any stockholder proposals, (iv) calling an annual
or special meeting of stockholders,  or (v) soliciting proxies from stockholders
of the Company.  The  Agreement,  however,  does not restrict the Filing Parties
from (a)  nominating  one or more persons for election as director at any annual
meeting after the Company's  2008 annual  meeting or (b)  soliciting  proxies or
consents  with respect to Company  voting  stock  (including  taking  actions in
support or furtherance of any such  solicitation  including to cause  cumulative
voting to be in effect) (i) in favor of or in  opposition to the election of any
persons  so  nominated  for  election  to the Board of  Directors  at any annual
meeting after the Company's  2008 annual  meeting or (ii) in regard to any other
matter that may be brought before the Company's  stockholders  by the Company or
any other  stockholder  at any annual  meeting after the  Company's  2008 annual
meeting.

          Depending  upon OPP's view of the  Company's  business  and  financial
prospects  and  general  market   conditions,   the  Partnerships  may  purchase
additional Shares or dispose of Shares at any time or from time to time.


Item 6.   Contracts, Arrangements, Understandings or Relationships
          With Respect to Securities of the Issuer.
          -----------------------------------------

          Item 6 is hereby  amended by deleting  Item 6 in its  entirety  and by
substituting the following in lieu thereof:

          As described in Item 4 above,  on January 31, 2008 the Filing  Parties
entered into the Agreement.  In addition to the terms of the Agreement described
in Item 4 above,  the Agreement  provides that,  during the effective  period of
certain restrictions set forth therein, the Filing Parties will cause any Shares
held by the  Partnerships to be voted in accordance with the  recommendation  of
the  Company's  Board of  Directors  if Mr. Press has approved and joined in any
such recommendation.

          The  descriptions  of the Agreement set forth in this Schedule 13D, as
amended,  are qualified in their entirety by reference to the complete agreement
governing such matters,  which is incorporated by reference to this Schedule 13D
Amendment No. 3 as an exhibit pursuant to Item 7 hereof.

          Except as otherwise  described  herein,  no  contracts,  arrangements,
understandings or similar  relationships exist with respect to the securities of
the Company  between the Filing  Parties or the  Partnerships  and any person or
entity.
