Paying Agent to Hold Money in Trust. ----------------------------------- The Issuers shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, premium, if any, or interest on Notes (whether such assets have been distributed to it by the Issuers or any other obligor on the Notes), and shall notify the Trustee in writing of any Default in making any such payment. The Issuers at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to forthwith distribute to the Trustee all assets so held in trust by such Paying Agent together with a complete accounting of such sums. Upon doing so, the Paying Agent shall have no further liability for such assets. Section 2.05. Noteholder Lists. ---------------- The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Noteholders. If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee on or before each March 1 and September 1 in each year, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Noteholders. -54- Section 2.06. Transfer and Exchange. --------------------- When a Note is presented to the Registrar with a request to register the transfer thereof, the Registrar shall register the transfer as requested if the requirements of applicable law are met and, when Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other authorized denominations, the Registrar shall make the exchange as requested; provided that every Note presented or surrendered for registration of -------- transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Issuers and the Registrar duly executed by the Holder thereof or his attorney duly authorized in writing. To permit transfers and exchanges, upon surrender of any Note for registration of transfer at the office or agency maintained pursuant to Section 2.03 hereof, the Issuers shall execute and the Trustee shall authenticate Notes at the Registrar's request. Any exchange or transfer shall be without charge, except that the Issuers may require payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation to a transfer or exchange, but this provision shall not apply to any exchange pursuant to Sections 2.09, 3.06 or 8.05 hereof. The Trustee shall not be required to register transfers of Notes or to exchange Notes for a period of 15 days before selection of any Notes to be redeemed. The Trustee shall not be required to exchange or register transfers of any Notes called or being called for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. Any Holder of the Global Note shall, by acceptance of such Global Note, agree that transfers of the beneficial interests in such Global Note may be effected only through a book entry system maintained by the Depository of such Global Note (or its agent), and that ownership of a beneficial interest in the Global Note shall be required to be reflected in a book entry. -55- Section 2.07. Replacement Notes. ----------------- If a mutilated Note is surrendered to the Trustee or if the Holder presents evidence to the satisfaction of the Issuers and the Trustee that the Note has been lost, destroyed or wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a replacement Note. An indemnity bond may be required by the Issuers or the Trustee that is sufficient in the judgment of the Issuers and the Trustee to protect the Issuers, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. In every case of destruction, loss or theft, the applicant shall also furnish to the Issuers and to the Trustee evidence to their satisfaction of the destruction, loss or the theft of such Note and the ownership thereof. Each of the Issuers and the Trustee may charge for its expenses in replacing a Note. Every replacement Note is an additional obligation of the Issuers. In the event any such mutilated, lost, destroyed or wrongfully taken Note has become due and payable, the Issuers in their discretion may pay such Note instead of issuing a new Note in replacement thereof. The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes. Section 2.08. Outstanding Notes. ----------------- Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, and those described in this Section 2.08 as not outstanding. If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding until the Issuers and the Trustee receive proof satisfactory to each of them that the replaced Note is held by a bona fide purchaser. If a Paying Agent holds on a Redemption Date or Maturity Date money sufficient to pay the principal of, premium, if any, and accrued interest on Notes payable on that date, -56- then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. Subject to Section 12.06, a Note does not cease to be outstanding solely because the Issuers or any Affiliate of an Issuer hold the Note. Section 2.09. Temporary Notes. --------------- Until definitive Notes are ready for delivery, the Issuers may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry all rights, of definitive Notes but may have variations that the Issuers consider appropriate for temporary Notes. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes presented to it. Section 2.10. Cancellation. ------------ The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee shall cancel and retain or, upon written request of the Issuers, may destroy or return to the Issuers in accordance with its normal practice, all Notes surrendered for transfer, exchange, payment or cancellation and if such Notes are destroyed, deliver a certificate of destruction to the Issuers. Subject to Section 2.07 hereof, the Issuers may not issue new Notes to replace Notes in respect of which they have previously paid all principal, premium and interest accrued thereon, or delivered to the Trustee for cancellation. Section 2.11. Defaulted Interest. ------------------ If the Issuers default in a payment of interest on the Notes, they shall pay the defaulted amounts, plus any interest payable on defaulted amounts pursuant to Section 4.01 hereof, to the persons who are Noteholders on a subsequent special record date. The Issuers shall fix the special record -57- date and payment date in a manner satisfactory to the Trustee and provide the Trustee at least 20 days notice of the proposed amount of defaulted interest to be paid and the special payment date. At least 15 days before the special record date, the Issuers shall mail or cause to be mailed to each Noteholder at its address as it appears on the Notes register maintained by the Registrar a notice that states the special record date, the payment date (which shall be not less than five nor more than ten days after the special record date), and the amount to be paid. In lieu of the foregoing procedures, the Issuers may pay defaulted interest in any other lawful manner satisfactory to the Trustee. Section 2.12. Deposit of Moneys. ----------------- Prior to 10:00 a.m., New York City time, on each Interest Payment Date, Redemption Date and Maturity Date, the Issuers shall have deposited with the Paying Agent in immediately available funds U.S. legal tender sufficient to make payments, if any, due on such Interest Payment Date, Redemption Date or Maturity Date, as the case may be, in a timely manner which permits the Trustee to remit payment to the Holders on such Interest Payment Date, Redemption Date or Maturity Date, as the case may be. The principal and interest on Global Notes shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole holder of the Global Notes represented thereby. The principal and interest on Notes in certificated form shall be payable at the office of the Paying Agent. Section 2.13. CUSIP Number. ------------ The Issuers in issuing the Notes may use one or more "CUSIP" numbers, and if so, the Trustee shall use such CUSIP numbers in notices of redemption or exchange as a convenience to Holders, provided that any such notice may state -------- that no representation is made as to the correctness or accuracy of the CUSIP numbers printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. -58- Section 2.14. Book-Entry Provisions for Global Notes. -------------------------------------- (a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository and (ii) bear legends as set forth in Exhibit B. Members of, or participants in, the Depository ("Agent Members") shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository or under the Global Note, and the Depository may be treated by the Issuers, the Trustee and any agent of the Issuers or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder. (b) Interests of beneficial owners in the Global Notes may be transferred or exchanged for Certificated Notes in accordance with the rules and procedures of the Depository and the provisions of Section 2.15.
