Upon the occurrence of a Change of Control Triggering Event (as defined in the Indenture) with respect to a series of Notes, unless the Company has redeemed such series of Notes in full, has defeased the Notes or has satisfied and discharged the Notes, each holder of Notes of such series will have the right to require that the Company repurchase any and all of such holder's Notes of such series at a purchase price equal to 101% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, thereon, to, but excluding, the date of purchase.

The Indenture contains covenants that limit the ability of the Company and its restricted subsidiaries to, among other things: (i) create liens on certain assets to secure debt; (ii) enter into certain sale and leaseback transactions; and (iii) in the case of the Company, consolidate with, merge into or sell, convey or lease all or substantially all of the Company's assets to any other person, in each case as set forth in the Indenture. These covenants are, however, subject to a number of important limitations and exceptions.

The Indenture also contains customary event of default provisions including, among others, the following: (i) default in the payment of principal of, or premium, if any, on any such series of Notes when due and payable; (ii) default in the payment of any interest on any such series of Notes when it becomes due and payable, and continuance of that default for a period of 30 days; (iii) default in the performance or breach of any other covenant by the Company in the Indenture (other than a covenant that has been included in the Indenture solely for the benefit of a series of debt securities other than the Notes of such series), which default continues uncured for a period of 90 days; (iv) default in the payment of any other indebtedness or other default on any indebtedness, which default results in the acceleration of such indebtedness, in each case in excess of $250,000,000, and continuance of such default for a period of 30 days; and (v) certain events of bankruptcy, insolvency or reorganization of the Company, and continuance of such events for 60 days.
