A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Indenture, or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series. 9. Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) default by the Issuers for 30 days in payment of any interest on the Securities; (ii) default by the Issuers in any payment of principal of (or premium, if any, on) the Securities; (iii) default by the Issuers in observing or performing any of their other covenants or agreements in, or provisions of, the Securities or in the Indenture which shall not have been remedied within 60 days after written notice to the Issuers by the Trustee or to the Issuers and Trustee by the holders of at least 25% in aggregate principal amount of the Debt Securities then outstanding affected by such default; or (iv) certain events involving bankruptcy, insolvency or reorganization affecting the Issuers. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Securities of the series affected by such default (or, in the case of an Event of Default described in clause (iii) above, if outstanding Debt Securities of other series are affected by such Default, then at least 25% in principal amount of the then outstanding Debt Securities so affected), may declare the principal of and interest on all the Securities to be immediately due and payable, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization affecting the Issuers, all outstanding Securities become due and payable immediately without further action or notice. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus accrued interest to the date of payment. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities (or affected Debt Securities) may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or may direct the Trustee in its exercise of any trust or power conferred on the Trustee. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. The Issuers must furnish an annual compliance certificate to the Trustee. 4 10. Discharge Prior to Maturity. The Indenture with respect to the Securities shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds or U.S. Government Obligations sufficient for such payment. 11. Trustee Dealings with the Issuers. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuers or their Affiliates, and may otherwise deal with the Issuers or their Affiliates, as if it were not Trustee. 12. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Issuers shall not have any liability for any obligations of the Issuers under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 13. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 14. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed thereon. 15. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 16. Restrictions on Transfer; Additional Rights of Holders of Transfer Restricted Securities. By its acceptance of any Security bearing a legend restricting transfer, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in the officers' certificate executed pursuant to Section 2.04 of the Indenture in respect of the Securities and such legend and agrees that it will transfer such Security only as provided in such officers' certificate and in the Indenture.
