(n) To the extent that any provision of the Indenture or the Notes provides for the payment of interest on overdue principal of, or premium, if any, or interest (including, without limitation, any Additional Interest which may be payable pursuant to the Registration Rights Agreement) on any Notes, then, to the extent permitted by law, interest on such overdue principal, premium, if any, and interest shall accrue at the rate of interest borne by such Notes (and, if Additional Interest shall at any time accrue on the Notes pursuant to the Registration Rights Agreement, then the per annum interest rate borne by the 4 3/8% Notes and by the 5 3/4% Notes for each day on which such Additional Interest shall accrue shall be deemed to be equal to the respective sums of 4 3/8% and 5 3/4% per annum plus the respective per annum rate at which such Additional Interest shall accrue for such day), and, anything in the Indenture to the contrary 6 notwithstanding, in the case of any requirement in the Indenture that the Company pay (or that the Trustee distribute) interest on overdue principal of, or premium, if any, or interest on the Notes, such payment or distribution shall only be required to the extent it is permitted by applicable law.

(s) The Notes shall be in substantially the form attached hereto as Exhibit A, which form is incorporated by reference in and made a part of this First Supplemental Indenture and the Indenture as if set forth in full herein and therein, provided that the form of any Additional Notes may have such variations as are permitted by Section 2(a) of this First Supplemental Indenture; and provided, further, that Physical Notes may deviate (in form but not in substance) from the form attached as Exhibit A to this First Supplemental Indenture in such respects as the Company may deem necessary or appropriate to protect against fraud or forgery, including without limitation, by changing the form of the Physical Notes so that they have a "face" and a "reverse" 7 and by moving the signatures and Trustee's certificate of authentication so that they appear on the same page as the principal amount of the Physical Notes. SECTION 3. AMENDMENTS TO ARTICLE THREE. (a) Article Three of the Original Indenture is hereby amended, solely insofar as relates to the Notes, by adding at the end thereof the following new Sections 311, 312 and 313: "Sections 311.

Notwithstanding the foregoing, to the extent that a certificate substantially in the form of Exhibit B hereto shall be delivered with respect to a portion (but not all) of the principal amount of a Regulation S Global Note bearing the Private Placement Legend, then the Company shall execute and the Trustee shall authenticate and deliver a Regulation S Global Note not bearing the Private Placement Legend in exchange for only such portion of the principal amount of the Regulation S Global Note bearing the Private Placement Legend in respect of which such certification shall have been so delivered, and the Trustee shall reflect on its books and records the date and a decrease in the principal amount of such Regulation S Global Note bearing the Private Placement Legend and a like increase in the principal amount of the Regulation S Global Note not bearing the Private Placement Legend."

In addition, U.S. Physical Notes and Regulation S Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in 144A Global Notes and Regulation S Global Notes, respectively, under the circumstances set forth in the seventh paragraph of Section 305 of this Indenture. "(c) Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in another Global Note will, upon transfer, cease to be an interest in the first such Global Note and become an interest in such other Global Note and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. "(d) In connection with any transfer of a portion of the beneficial interests in a 144A Global Note or Regulation S Global Note to beneficial owners who will take such interests in the form of Physical Notes (other than transfers of an entire 144A Global Note or an entire Regulation S Global Note pursuant to the seventh paragraph of Section 305 of this Indenture), the Trustee shall reflect the date and a decrease in the principal amount of such 144A Global Note or Regulation S Global Note, as the case may be, in an amount equal to the principal amount of the beneficial interest in such Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more corresponding U.S. Physical Notes or Regulation S Physical Notes, as the case may be, of like tenor and principal amount.

"(f) GENERAL. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture. The Trustee shall not register a transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set forth in this Indenture. In connection with any transfer of Notes to an Institutional Accredited Investor or in a transfer being made pursuant to Rule 904 under the Securities Act or pursuant to Rule 144 under the Securities Act (if available), each Holder agrees by its acceptance of such Notes to furnish the Trustee such certifications, legal opinions or other information as the Company may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act; provided that the Trustee shall not be required to determine (but may conclusively rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information. "In case of any transfer or exchange of Notes or interests in Notes bearing the Private Placement Legend, the procedures and requirements for which are not addressed in detail in this Section 313 or elsewhere in this Indenture, such transfer or exchange will be subject to such procedures and requirements as may be reasonably prescribed by the Company from time to time (and which shall be consistent with the procedures and requirements set forth in this Section 313) and, in the case of a transfer or exchange involving a Global Note or an interest therein, the procedures of the Depository. In case of any request for the removal of the Private Placement Legend from a Note, the procedures and requirements 14 for which are not addressed in detail in this Indenture, the Company may permit the removal of such legend upon the receipt of such legal opinions, certificates and other documents as it may require to establish that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the Securities Act and by delivery to the Trustee of a Company Order directing that such legend be removed. "The Trustee shall retain copies of all letters, notices and other written communications received pursuant to Section 312 or this Section 313 in accordance with its customary procedures. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Trustee.

"Following the initial issuance of the Notes, nothing in this Indenture shall limit the ability of any Institutional Accredited Investor to own (subject to compliance with the applicable transfer restrictions set forth in this Indenture) beneficial interests in a Rule 144A Global Note. "The Trustee shall not be responsible for obtaining any documentation contemplated by this Section 313 in connection with transfers that occur within the same Global Note and which occur without the involvement of the Trustee."
