We currently expect that we will contribute approximately $45 million
to our pension plans in the second half of 2010 and that $40.5
million of that contribution will be made using shares of our common
stock. The number of shares we may use to fund that portion of the
contribution will not exceed 4.5 million.

and a reconciliation measure, the Health Care and Education Reconciliation Act of 2010,
(collectively, the Act) will not have a material
impact on our results of operations, financial position or cash flows. However, we are continuing
to evaluate the provisions of the Act and ongoing, related regulatory activity to determine their
potential impact, if any, on our health care benefit costs.
