          5-Year Revolving Credit Agreement with J.P. Morgan Chase Bank, N.A., as
          Administrative Agent, and a syndicate of banks, as lenders, dated as of
          April 1,
          2005. Material terms of the amendment are described in Item 2.03, which
          is
          incorporated by reference into this Item 1.01. The Third Amendment to 5-Year
          Revolving Credit Agreement is included as Exhibit 10.1 to this Current

Amendment
          to Term Loan Agreement
. On March 19, 2007, the Company, Bank of America,
          N.A., as Administrative Agent, and a syndicate of banks, as lenders, entered
          into an amendment to the Company's $300 million Term Loan Credit Agreement,
          dated as of November 10, 2004. The amendment conforms the covenants contained
          in
          the term loan to be the same as contained in the 5-Year Revolving Credit
          Agreement, which was amended as of the same date. Other changes included
          extending the maturity date two years to April 1, 2012, reducing
          the spread on our Eurodollar loans, increasing the ratio of debt
          to total capitalization limit from 60% to 65%, and replacing the
