ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         The total  amount  of funds  used by each of the  Partnerships  and OSS
Overseas to purchase  the  securities  of the  Company as  described  herein was
furnished from the investment  capital of the Partnerships and OSS Overseas,  as
applicable.

         Included in the total securities  beneficially  owned by the Investment
Manager,  SB LLC and Mr. Schafer were 73,363 Ordinary Shares which were held for
the benefit of a third  party in a  separately  managed  account  (the  "Managed

         Mr.  Grondin  has  investment   discretion  over  800  Ordinary  Shares
purchased for his personal account.

ITEM 4.       PURPOSE OF TRANSACTION.

         On March 9, 2007, the  Investment  Manager sent a letter to the Company
expressing its concern regarding the Company's operating performance relative to
its  peers  and with  the  management's  lack of  concern  regarding  the gap in
performance.  The  Investment  Manager also noted that a member of the Company's
Board  of  Directors  was  stepping  down  and  suggested  a  candidate  for his
replacement.

         On April 9, 2007, the Company's  Chief  Executive  Officer  visited the
Investment  Manager's  offices.  In a letter on April 26, 2007,  the  Investment
Manager  reiterated  its  concern  that the  Company  was  underperforming.  The
Investment Manager requested a committee of independent  directors be formed and
that the committee  retain an  independent  investment  bank to advise as to how
shareholder value could be best maximized.

         The Reporting  Persons intend to review their investment in the Company
on a continuing basis and may engage in discussions  with management,  the Board
of  Directors,  other  shareholders  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 their investment in the Company as they
deem appropriate including, without limitation,  purchasing additional shares or
selling some or all of their shares, engaging in short selling of or any hedging
or similar  transactions  with respect to the shares and/or  otherwise  changing
their  intention  with  respect to any and all matters  referred to in Item 4 of
Schedule 13D.

         Copies of the March 9, 2007 and the April 26, 2007 letters are attached
hereto as Exhibit A and Exhibit B and are incorporated by reference.
