SUBORDINATED NOTES DUE 3/15/24.

NOTE: Tradewinds Global Investors LLC ("Tradewinds") is an affiliate of NWQ
Investment Management Company ("NWQ"). NWQ previously had reported beneficial
ownership of securities under Section 13(d) of the Exchange Act of 1934, as
amended (the "Exchange Act") and Regulation 13D/G thereunder on behalf of itself
and Tradewinds. Tradewinds was formed as a legal entity in the fourth quarter of
2005 and commenced operation in 2006. Since that time, the two firms worked to
achieve operational separation of their investment management and proxy voting
functions, which separation was completed as of June 30, 2007. Accordingly, this
filing is being made to report Tradewinds's beneficial ownership of the Issuer's
securities independently from that of NWQ.

Both NWQ and Tradewinds are wholly owned subsidiaries of Nuveen Investments,
Inc. ("Nuveen"), a parent company with several subsidiaries engaged in the
investment management business. Nuveen has adopted internal operating policies
to ensure that investment management and voting decisions are made independently
by investment personnel at its investment management subsidiaries. Accordingly,
hereafter NWQ and Tradewinds (like Nuveen's other investment management
subsidiaries) anticipate independently reporting beneficial ownership of
securities pursuant to Section 13(d) of the Exchange Act and Regulation 13D/G
thereunder.
