The Early Settlement Date for Notes accepted for purchase on the Early Acceptance Date, if any, is expected to be October 5, 2012, but may change depending on when (or if) the Financing Condition is satisfied.

The Offer will expire at 17:00 hours CET (11:00 a.m., New York City time), on October 16, 2012, unless extended or earlier terminated by the Company, and the Final Settlement Date, if any, is expected to be October 18, 2012, but also may change depending on when (or if) the Financing Condition referred to above is satisfied and also depending on the amount of Notes tendered after the Early Tender Time.
