For so long as any of the Notes constitute “restricted securities” within the meaning of Rule 144(a)(3) promulgated under the Securities Act, the Company shall, if the Company is not then subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, furnish to any Holder or beneficial owner of such Notes, or to any prospective purchaser of such Notes designated by such Holder or beneficial owner, in each case upon the written request of such Holder, beneficial owner or prospective purchaser, the information required to be provided pursuant to Rule 144A(d)(4) promulgated under the Securities Act.

(b) The following provisions shall apply with respect to any proposed transfer of any Transfer Restricted Note prior to the expiration of the holding period applicable to sales of such Notes under Rule 144, and the Security Registrar shall refuse to register any transfer of such Notes not complying with the restrictions set forth in the Restricted Notes Legend and in this Section 3. In addition to the requirements set forth in Section 3.05 of the Indenture, Transfer Restricted Notes that are presented or surrendered for registration of transfer or exchange pursuant to Section 3.05 of the Indenture shall be accompanied by the following additional information and documents, as applicable, upon which the Security Registrar may conclusively rely:

(i) if such Transfer Restricted Notes are being delivered to the Security Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in substantially the form of Exhibit B hereto);

(ii) if such Transfer Restricted Notes are being transferred (1) to a QIB in accordance with Rule 144A or (2) pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form of Exhibit B hereto);

(iii) if such Transfer Restricted Notes are being transferred pursuant to an exemption from registration in accordance with Rule 903 or Rule 904 of Regulation S, certifications to that effect from such Holder (in substantially the form of Exhibit B and Exhibit C hereto); or

(iv) if such Transfer Restricted Notes are being transferred in reliance on and in compliance with (1) an exemption from registration in accordance with Rule 144 under the Securities Act or (2) another exemption from the registration requirements of the Securities Act, a certification to that effect from such Holder (in substantially the form of Exhibit B attached hereto) and an opinion of counsel, certification or other evidence as may reasonably be required to that effect if the Company or the Trustee so requests.

(c) A Holder of a beneficial interest in a Regulation S Global Note who wishes to transfer its interest in such Note to a QIB in accordance with Rule 144A who takes delivery in the form of a beneficial interest in such Rule 144A Global Note shall deliver to the Security Registrar a certification to that effect (in substantially the form of Exhibit C attached hereto) upon which the Security Registrar may conclusively rely. After the expiration of the Restricted Period, interests in the Regulation S Global Note may be transferred without requiring the certification set forth in this Section 3(c).

(d) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depositary, in accordance with Section 3.05 of the Indenture and Section 3 and Section 4 hereof (including the restrictions on transfer set forth therein and herein) and the rules and procedures of the Depositary therefor, which shall include restrictions on transfer comparable to those set forth therein and herein to the extent required by the Securities Act; provided, however, that prior to the expiration of the Restricted Period, transfers and exchanges of beneficial interests in the Regulation S Global Note may be made pursuant to such restrictions only (1) to a Person that is not a U.S. person or for the account or benefit of a Person that is not a U.S. person within the meaning of Regulation S under the Securities Act or (2) to a QIB, in each case that hold such interests through Euroclear or Clearstream.

(e) If Notes are issued upon the registration of transfer, exchange or replacement of Notes not bearing the Restricted Notes Legend, the Notes so issued shall not bear such legend. If Notes are issued upon the registration or transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, or if a request is made to remove the Restricted Notes Legend on a Note, the Notes so issued shall bear the Restricted Notes Legend, or the Restricted Notes Legend shall not be removed, as the case may be, unless there is delivered to the Company such satisfactory evidence, which may include an opinion of counsel, as may be reasonably required by the Company that neither the Restricted Notes Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A, Rule 144 or Regulation S, that such Notes are not “restricted securities” within the meaning of Rule 144 or that such Notes were transferred pursuant to an effective registration statement under the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the direction of the Company, shall authenticate and deliver a Note that does not bear the Restricted Notes Legend. If a Restricted Notes Legend is removed from the face of a Note and the Note is subsequently held by an Affiliate of the Company, the Restricted Notes Legend shall be reinstated.

(f) Neither the Trustee nor the Security Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed

under this Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so only if and when expressly required by the terms of, this Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. Notwithstanding anything herein to the contrary, neither the Trustee nor the Security Registrar shall have any responsibility to receive any letters, opinions or certifications, nor any responsibility to monitor compliance with any transfer restrictions, in connection with any transfer or exchange of any beneficial interest in a Global Note for a beneficial interest in the same Global Note.

(g) Notwithstanding the foregoing, in the event that any Transfer Restricted Notes are exchanged for Exchange Notes in connection with an effective registration statement pursuant to the Registration Rights Agreement, the Company shall issue and, at the direction of the Company, the Trustee shall authenticate the Exchange Notes in exchange for Transfer Restricted Notes accepted for exchange in the exchange offer, which Exchange Notes shall not bear the Restricted Notes Legend, and the Security Registrar shall rescind any restriction on the transfer of such Exchange Notes.

Section 4. Form of Notes/Legends.

(a) The Notes are being offered only to (A) Persons reasonably believed to be QIBs in reliance on Rule 144A and (B) non U.S. persons in reliance on Regulation S. Such Notes may thereafter be transferred to, among others, QIBs, and purchasers in reliance on Regulation S. Exchange Notes exchanged for interests in the Rule 144A Notes and the Regulation S Notes will be issued in the form of permanent Global Notes deposited with the Trustee as hereinafter provided, including the appropriate legend set forth in the form of security attached as Exhibit A (the “Exchange Global Notes”). The Exchange Global Notes will be deposited upon issuance with, or on behalf of, the Trustee as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The Exchange Global Notes may be represented by more than one certificate, if so required by the Depositary’s rules regarding the maximum principal amount to be represented by a single certificate.

(b) The Notes offered to QIBs in the United States of America in reliance on Rule 144A (the “Rule 144A Notes”) shall be issued in the form of a permanent global note including appropriate legends as set forth in the form of security attached as Exhibit A (the “Rule 144A Global Note”), deposited with the Trustee, as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The Rule 144A Global Note may be represented by more than one certificate, if so required by the Depositary’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Rule 144A Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, or its nominee, as hereinafter provided.

(c) The Notes offered to non U.S. persons outside the United States of America (the “Regulation S Notes”) in reliance on Regulation S shall be issued in the form of a permanent global note including appropriate legends as set forth in the form of security attached hereto as Exhibit A (the “Regulation S Global Note” and, together with the Rule 144A Global Note and the Exchange Global Notes, the “Global Notes”). The Regulation S Global Note will be deposited upon issuance with, or on behalf of, the Trustee as custodian for the Depositary. Prior to the 40th day after the date the Notes are issued (such period through and including such 40th day, the “Restricted Period”), interests in the Regulation S Global Note may only be transferred to non U.S. persons pursuant to Regulation S, unless exchanged for interests in a Global Note in accordance with the transfer and certification requirements described herein. Investors may hold their interests in the Regulation S Global Note through organizations other than Euroclear or Clearstream that are participants in the Depositary’s system or directly through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations which are participants in such systems. If such interests are held through Euroclear or Clearstream, Euroclear and Clearstream will hold such interests in the applicable Regulation S Global Note on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. Such depositaries, in turn, will hold such interests in the applicable Regulation S Global Note in customers’ securities accounts in the depositaries’ names on the books of the Depositary. The Regulation S Global Note may be represented by more than one certificate, if so required by the Depositary’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Regulation S Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary or its nominee, as hereinafter provided.
