beneficially owned by the Reporting Persons were acquired at an aggregate
purchase price of approximately $283,110,199. Such shares are held by the
Reporting Persons in commingled margin accounts maintained at UBS Securities
LLC, which may extend margin credit to the Reporting Persons from time to time,
subject to applicable federal margin regulations, stock exchange rules and
credit policies. In such instances, the positions held in the margin account are
pledged as collateral security for the repayment of debit balances in the
account. The margin accounts bear interest at a rate based upon the broker's
call rate from time to time in effect. Since other securities are held in the
accounts, it is not possible to determine the amounts, if any, of margin used to
purchase the shares of Common Stock reported herein.

Item 4.     Purpose of the Transaction.

          The Reporting Persons originally acquired the shares of Common Stock
in the ordinary course of business because they believed that the shares, when
purchased, were undervalued and represented an attractive investment
opportunity. The Reporting Persons have engaged, and expect to continue to
engage, in discussions with management, the board of directors, other
shareholders of the Issuer and other relevant parties concerning the business,
operations, management, strategy, board composition and future plans of the
Issuer, with a view to maximizing long-term value for shareholders.

          Except as described 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 their investment in the Issuer on a continuing basis. Depending on
various factors including, without limitation, the Issuer's financial position
and strategic direction, the outcome of the discussions referenced above,
actions taken by the board of directors, price levels of the Common Stock, 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 Issuer as they deem appropriate including, without limitation, purchasing
additional Common Stock or selling some or all of their Common Stock, engaging
in short selling of or any hedging or similar transactions with respect to the
Common Stock and/or otherwise changing their intention with respect to any and
all matters referred to in Item 4 of Schedule 13D.
