The Company and the Guarantors registered the sale of the Securities with the Securities and Exchange Commission pursuant to a shelf registration statement (the "Registration Statement") on Form S-3 (File No. 333-173135) filed on March 29, 2011.

The Indenture also restricts the ability of the Company and the Guarantors to consolidate, merge or transfer all or substantially all of their assets, and requires the Company to offer to repurchase the Notes upon certain change of control events.
