(j) Automatic Exchange from Transfer Restricted Note to Unrestricted Global Note. Upon the Company’s satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act, the Company may, at its option, cause beneficial interests in a Transfer Restricted Note to be automatically exchanged into beneficial interests in an Unrestricted Global Note without any action required by or on behalf of the Holder (the “Automatic Exchange”) at any time on or after the date that is the 366th calendar day after the date on which the Senior Notes are issued, or, if such day is not a Business Day, on the next succeeding Business Day (the “Automatic Exchange Date”). Upon the Company’s satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act, the Company may, at its option, (i) provide written notice to The Depository Trust Company (“DTC”) and the Trustee at least fifteen (15) calendar days prior to the Automatic Exchange Date, instructing DTC to exchange all of the outstanding beneficial interests in a particular Transfer Restricted Note to the Unrestricted Global Note, which the Company shall have previously otherwise made eligible for exchange with the DTC, (ii) provide prior written notice (the “Automatic Exchange Notice”) to each Holder at such Holder’s address appearing in the register of Holders at least fifteen (15) calendar days prior to the Automatic Exchange Date (the “Automatic Exchange Notice Date”), which notice must include (w) the Automatic Exchange Date, (x) the section of this Senior Note pursuant to which the Automatic Exchange shall occur, (y) the “CUSIP” number of the Transfer Restricted Note from which such Holder’s beneficial interests will be transferred and (z) the “CUSIP” number of the Unrestricted Global Note into

12

which such Holder’s beneficial interests will be transferred, and (iii) on or prior to the Automatic Exchange Date, deliver to the Trustee for authentication one or more Unrestricted Global Notes, duly executed by the Company and an Company Order requesting the Trustee to authenticate, in an aggregate principal amount equal to the aggregate principal amount of Transfer Restricted Notes to be exchanged into such Unrestricted Global Notes. At the Company’s written request on no less than five (5) calendar days’ notice prior to the Automatic Exchange Notice Date, the Trustee shall deliver, in the Company’s name and at its expense, the Automatic Exchange Notice, which shall be prepared by the Company, to each Holder at such Holder’s address appearing in the register of Holders. Notwithstanding anything to the contrary in this Section 5(j), during the fifteen (15) calendar day period prior to the Automatic Exchange Date, no transfers or exchanges other than pursuant to this Section 5(j) shall be permitted without the prior written consent of the Company. As a condition to any Automatic Exchange, the Company shall provide, and the Trustee shall be entitled to conclusively rely upon, an Officer’s Certificate and Opinion of Counsel to the Company to the effect that the Automatic Exchange shall be effected in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act and that the aggregate principal amount of the particular Transfer Restricted Note is to be transferred to the particular Unrestricted Global Note by adjustment made on the records of the Trustee, as custodian for the Depositary to reflect the Automatic Exchange. Upon such exchange of beneficial interests pursuant to this Section 5(j), the aggregate principal amount of the Global Notes shall be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, to reflect the relevant increase or decrease in the principal amount of such Global Note resulting from the applicable exchange. The Restricted Global Note from which beneficial interests are transferred pursuant to an Automatic Exchange shall be cancelled following the Automatic Exchange and disposed of in accordance with the Trustee’s procedures for the disposition of cancelled securities.

(a) A Global Note deposited with the Depositary or with the Trustee as Custodian pursuant to Section 4 of this Officer’s Certificate or issued in connection with an Exchange Offer may be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 5 of this Officer’s Certificate and (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Note or if at any time the Depositary ceases to be a “clearing agency” registered under the Exchange Act and, in each case, a successor depositary is not appointed by the Company within 90 days of such notice or after the Company becomes aware of such cessation, (ii) the Company, at its option, notifies the Trustee in writing that it elects to exchange in whole, but not in part, the Global Note for Definitive Notes or (iii) an Event of Default has occurred and is continuing and the Depositary so requests (or a beneficial owner thereof requests such exchange in writing delivered through the Depositary). In addition, any Affiliate of the Company that is a beneficial owner of all or part of a Global Note may have such Affiliate’s beneficial interest transferred to such Affiliate in the form of a Definitive Note by providing a written request to the Company and the Trustee and such Opinions of Counsel, certificates or other information as may be required by the Indenture or the Company or Trustee.

(b) Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section 6 shall be surrendered by the Depositary to the Trustee, to be so transferred, in whole

13

or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 6(a) shall be executed, authenticated and delivered only in denominations of $2,000 and integral multiples of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any Definitive Note delivered in exchange for an interest in a Global Note that is a Transfer Restricted Note shall, except as otherwise provided by Section 5(e) of this Officer’s Certificate, bear the Restricted Notes Legend.

(c) The registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Senior Notes.

(d) In the event of the occurrence of any of the events specified in Section 6 of this Officer’s Certificate, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Notes in fully registered form without interest coupons.

(b) The statements contained in this certificate are based upon my familiarity with the Indenture and the documents accompanying this certificate, and upon my discussions with officers and employees of the Company familiar with the matters set forth herein.
