INTRODUCTORY NOTE

This Schedule 13G is being filed by Shapiro Capital Management LLC, an
investment adviser under the Investment Advisers Act of 1940. One or more of
Shapiro Capital Management LLC's advisory clients is the legal owner of the
securities covered by this statement. Pursuant to the investment advisory
agreements with its clients, Shapiro Capital Management LLC has the authority to
direct the investments of its advisory clients, and consequently to authorize
the disposition of the Issuer's shares. Effective February 3, 2006, Shapiro
Capital Management LLC underwent an internal reorganization which involved, in
part, the transfer of its investment advisory agreements to a new subsidiary,
Shapiro Capital Management LLC. Therefore effective February 3, 2006 Shapiro
Capital Management LLC was the beneficial owner of the shares reported in this
Schedule 13G.

This Schedule l3G is also being filed by Samuel R. Shapiro. Mr. Shapiro is the
chairman, a director and majority shareholder of Shapiro Capital Management LLC,
in which capacity he exercises dispositive power over the securities reported
herein by Shapiro Capital Management LLC. Mr. Shapiro, therefore, may be deemed
to have indirect beneficial ownership over such securities. Unless otherwise
indicated herein, Mr. Shapiro has no interest in dividends or proceeds from the
sale of such securities, owns no such securities for his own account and
disclaims beneficial ownership of all for securities reported herein by the
Shapiro Capital Management LLC. The aggregate number and percentage of the
Issuer's securities to with this Schedule 13G relates is 4,946,431 representing
7.65% of the Issuer's outstanding shares. The beneficial ownership reported by
Samuel R. Shapiro and Shapiro Capital Management LLC relates to the same shares
of the Issuer in which each such reporting person has a separate beneficial
interest.

As of December 31, 2006, Mr. Shapiro owned 25,000 of the Issuer for his own
account. He may be deemed to be the beneficial owner of the 4,946,431 shares as
disclosed in Item 4C of the Schedule 13G.

Item 6. Samuel R. Shapiro is the chairman, director and majority shareholder of
Shapiro Capital Management LLC. He owns 25,000 of the Issuer for his individual
account, but is deemed to have beneficial ownership of the shares reported on
the Schedule 13G by virtue of his affiliation with Shapiro Capital Management
LLC.

Shapiro Capital Management LLC. is an Investment Advisor registered under the
Investment Advisers Act of 1940 and some of its clients have the right to
receive dividends from the securities which it manages, however, no such client
has an interest relating to more than five percent of the class to which this
