The aggregate principal amount of CODES which may be authenticated and delivered under this Indenture is limited to $300 million (or up to $345 million if the option set forth in Section 2 of the Purchase Agreement is exercised in full), except for CODES authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of other CODES pursuant to Sections 2.7, 2.8, 2.12, 7.5 or 10.7, hereof. The CODES shall be issuable in denominations of $1,000 or integral multiples thereof.

(b) The CODES shall mature on December 15, 2033 (the “Stated Maturity”).

(c) The CODES shall bear Interest from December 17, 2003 until the principal amount thereof is paid or made available for payment, or until such date on which the CODES are converted, redeemed or purchased as provided herein at a per annum rate which will equal 3-month LIBOR, adjusted quarterly by the Calculation Agent in accordance with the Security attached as Annex A hereto, minus a spread of 125 basis points, which spread may be reset upon the occurrence of a Reset Transaction, to, but not including, the effective date of any succeeding Reset Transaction (as adjusted as provided herein and the CODES, the “Interest Rate”). The Interest Rate for the initial interest period commencing on the Closing Date shall be 0.0 (zero). Notwithstanding anything to the contrary contained herein or in the form of Security, the Interest Rate will never be less than zero. Interest shall be payable quarterly in arrears on each Interest Payment Date, commencing March 15, 2004, with interest payable in Dollars to Holders in whose names the CODES are registered at the close of business on the preceding Regular Record Date, except as otherwise provided herein and in the CODES.

(d) In addition, interest (the “Contingent Interest”) will accrue on each CODES during any quarterly interest period commencing with the quarterly interest period beginning December 15, 2009, if the average Trading Prices of a CODES for the five Trading Days ending on the second Trading Day immediately preceding the beginning of the relevant quarterly interest period equals 120% or more of the principal amount of such CODES. The amount of Contingent Interest payable in respect of any quarterly period will equal 0.0625% of the average Trading Price of the CODES over the measuring period triggering the Contingent Interest payment. Upon determination that Holders of CODES will be entitled to receive Contingent Interest during any relevant quarterly interest period, on or prior to the start of the relevant quarterly interest period, the Company shall issue a press release and publish information with respect to any Contingent Interest on its web site. The Company shall pay Contingent Interest, if any, in the same manner as it shall pay Interest pursuant to Section 2.1(c) hereof and the obligations of Holders in respect of the payment of Contingent Interest in connection with the conversion of any CODES will also be the same as described in Section 2.1(f) hereof.

(e) Interest (including Contingent Interest) on the CODES shall be computed on the basis of the actual number of days for which Interest is payable in the relevant interest period, divided by 360. For purposes of determining the Interest Rate, the Trustee may assume that a Reset Transaction has not occurred unless the Trustee has received an Officers’ Certificate stating that a Reset Transaction has occurred and specifying the Adjusted Spread then in effect.

(f) Interest (including Contingent Interest) shall be due and payable on a CODES as follows:

(1) A registered Holder of any CODES as of the close of business on a Regular Record Date shall be entitled (except as otherwise indicated in this Section 2.1(f)) to receive and shall receive, as the registered Holder as of such Regular Record Date, Interest (including Contingent Interest) on such CODES on the corresponding Interest Payment Date (other than any CODES whose Stated Maturity is prior to such Interest Payment Date).

(2) In the event that a CODES becomes subject to redemption pursuant to Article 10 and the Redemption Date occurs after a Regular Record Date, the Person whose CODES become subject to redemption (and only such Person rather than the Holder as of such Regular Record Date) shall be entitled to receive and shall receive accrued and unpaid Interest (including Contingent Interest) from the preceding Interest Payment Date (or such earlier date on which Interest, including Contingent Interest, if any, was last paid) to but not including the Redemption Date on such CODES, even if such Person is not the Holder of such CODES.

(3) In the event that a CODES becomes subject to purchase pursuant to Article 11, a Holder of any CODES who exercises a repurchase right with respect to such CODES shall be entitled to receive and shall receive Interest (including Contingent Interest) to but not including the applicable purchase date for such CODES, which amount shall be included in the applicable purchase price thereof.

(4) In the event that a CODES is converted pursuant to Article 12, the Holder who converts such CODES on any date other than an Interest Payment Date shall not be entitled to accrued and unpaid Interest (including Contingent Interest) from the preceding Interest Payment Date until the Conversion Date, or otherwise, on such CODES, such amounts being deemed to have been paid by receipt of shares of Common Stock in full rather than canceled, extinguished or forfeited; and, accordingly, a Holder which converts a CODES after a Regular Record Date but prior to the corresponding Interest Payment Date will receive accrued and unpaid Interest (including Contingent Interest) for such period on such Interest Payment Date but will be required to remit to the Company an amount equal to that Interest (including Contingent Interest) at the time such Holder surrenders the CODES for conversion The preceding sentence does not apply, however, to a Holder that converts, after a Regular Record Date for an interest payment date but prior to the corresponding Interest Payment Date, CODES that the Company calls for redemption prior to such conversion on a Redemption Date that is on or prior to the third Business Day after such Interest Payment Date.

(g) Payment of any principal, Redemption Price, Repurchase Price and Interest and Contingent Interest, if any, on, Global Securities shall be payable by the Company to the Depositary in immediately available funds.

(iii) Removal of the Restricted Securities Legends.

Each Security or share of Common Stock issued upon conversion of any CODES (other than shares of Common Stock issued upon conversion of a CODES that previously were sold pursuant to Rule 144, if available, or pursuant to a registration statement that has been declared effective under the Securities Act and which continues to be effective at the time of such sale) shall bear the applicable Restricted Securities Legend set forth in Section 2.3(a)(i) or 2.3(a)(ii), as applicable, until the earlier of:

The Holder must give notice thereof to the Trustee, as applicable.

In the event Rule 144(k) as promulgated under the Securities Act is amended to shorten the two-year period under Rule 144(k), then, the references in the restrictive legends set

forth above to “TWO YEARS”, and in the corresponding transfer restrictions described above, the Securities and the shares of Common Stock will be deemed to refer to such shorter period, from and after receipt by the Trustee of an Officers’ Certificate and an Opinion of Counsel to that effect. As soon as practicable after the Company knows of the effectiveness of any such amendment to shorten the two-year period under Rule 144(k), unless such changes would otherwise be prohibited by, or would cause a violation of, the U.S. federal securities laws applicable at the time, the Company will provide to the Trustee an Officers’ Certificate and an Opinion of Counsel as to the effectiveness of such amendment and the effectiveness of such change to the restrictive legends and transfer restrictions.

Notwithstanding the foregoing, the Restricted Securities Legend may be removed if there is delivered to the Company such satisfactory evidence, which may include an opinion of independent counsel, as may be reasonably required by the Company that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Securities or Common Stock will not violate the registration requirements of the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the written direction of the Company, shall authenticate and deliver in exchange for such Securities another Security or Securities having an equal aggregate principal amount that does not bear such legend. If the Restricted Securities Legend has been removed from a Securities as provided above, no other Security issued in exchange for all or any part of such Security shall bear such legend, unless the Company has reasonable cause to believe that such other Security is a “restricted security” within the meaning of Rule 144 and instructs the Trustee in writing to cause a Restricted Securities Legend to appear thereon.

Any Security (or security issued in exchange or substitution thereof) as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Restricted Securities Legend set forth therein or in Section 2.3(a)(iii) have been satisfied may, upon surrender of such Security for exchange to the Registrar in accordance with the provisions of Section 2.7 hereof, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount which shall not bear the Restricted Securities Legend required by Section 2.3(a)(i).

Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Restricted Securities Legend set forth therein or in Section 2.3(a)(iii) have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the Transfer Agent, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the Restricted Securities Legend required by Section 2.3(a)(ii).

(b) Global Security Legend.

Each Global Security shall also bear the following legend on the face thereof:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR

REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN ARTICLE 2 OF THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

Securities bearing the manual or facsimile signatures of individuals who were at the time of the execution of the Securities the proper Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of authentication of such Securities.

(b) At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise. No Security shall be entitled to any benefit under this Indenture, or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by or on behalf of the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. The Trustee may appoint an authenticating agent or agents reasonably acceptable to the Company with respect to the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

(c) Each Security shall be dated the date of its authentication. The Trustee shall authenticate and deliver Securities for original issue upon one or more Company Orders without any further action by the Company. The aggregate principal amount of Securities Outstanding at any time may not exceed $300 million (or up to $345 million if the Initial Purchasers’ option set forth in Section 2 of the Purchase Agreement is exercised in full). In the event that the Initial Purchasers exercise their option subsequent to the Closing Date, the Company may deliver to the Trustee a Company Order authorizing the Trustee to increase the aggregate principal amount of Securities Outstanding evidenced by a global Security, whereupon the Trustee shall make appropriate notation on the Schedule of Increases or Decreases in Global CODES evidencing the issuance by the Company of the additional principal amount of Securities that are the subject of the exercise by the Initial Purchasers of their option.

Section 2.5. Registrar, Paying Agent and Calculation Agent.

The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities (the “Register”) and of their transfer and exchange. The Company

may appoint one or more co-Registrars and one or more additional Paying Agents for the Securities. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any additional registrar. The Company may change any Paying Agent or Registrar without prior notice to any Holder.

The Company shall also appoint a Calculation Agent to perform the calculations required pursuant to this Indenture and the Securities.

The Company will cause each Paying Agent (other than The Bank of New York) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will:

(1) hold all sums of money or Common Stock held by it for the payment of any amounts due and payable in respect of the Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture;

(2) give the Trustee notice of any Default by the Company in the making of any such payment; and

(3) at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company shall give prompt written notice to the Trustee of the name and address of any Agent who is not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar, Paying Agent, or Calculation Agent, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent or Registrar; provided, however, that none of the Company, its subsidiaries or the Affiliates of the foregoing shall act:

(1) as Paying Agent in connection with redemptions, offers to purchase and discharges, except as otherwise specified in this Indenture, and

(2) as Paying Agent or Registrar if a Default or Event of Default has occurred and is continuing.

The Company hereby initially appoints The Bank of New York as Registrar, Paying Agent and Calculation Agent.

Section 2.6. Paying Agent to Hold Assets in Trust.

Not later than 10:00 a.m. (New York City time) on or prior to each due date of payments in respect of any Security, the Company shall deposit with one or more Paying Agents a sum of money in immediately available funds sufficient to make such payments when so becoming due. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company) shall have no further liability for the money so paid over to the Trustee.

The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any Default by the Company in making any such payment. At any time during the continuance of any such Default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money so held in trust.

If the Company shall act as a Paying Agent, it shall, prior to or on each such due date, segregate and hold in trust for the benefit of the Holders a sum sufficient with monies held by all other Paying Agents, to pay such amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture, and shall promptly notify the Trustee of its action or failure to act.

Section 2.7. General Provisions Relating to Registration, Transfer and Exchange.

The Securities are issuable only in registered form. A Holder may transfer a Security only by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Indenture. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Furthermore, any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Holder of such Global Security (or its agent) and that ownership of a beneficial interest in the Global Security shall be required to be reflected in a book-entry. Notwithstanding the foregoing, in the case of a Restricted Security, a beneficial interest in a Global Security that is transferred in reliance on an exemption from the registration requirements of the Securities Act other than in accordance with Rule 144 or Rule 144A may only be transferred for a Physical Security unless the transferee is the Company or a Subsidiary of the Company.

When Securities are presented to the Registrar with a request to register the transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if the requirements hereunder for such transactions are met (including that such Securities are duly endorsed or accompanied by a written instrument of transfer duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.4, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon issuances pursuant to Section 2.12 and exchanges pursuant to Sections 2.14, 7.5 or 10.7).

Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Securities:

(1) for a period of 15 days prior to the day of mailing of notice of redemption of Securities under Article 10 hereof;

(2) so selected for redemption or, if a portion of any Security is selected for redemption, such portion thereof selected for redemption; or

(3) surrendered for conversion or, if a portion of any Security is surrendered for conversion, such portion thereof surrendered for conversion.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.8. Book-Entry Provisions for the Global Securities.

(a) The Global Securities initially shall:

(1) be registered in the name of the Depositary;

(2) be delivered to the Trustee as custodian for such Depositary, for credit to the accounts of the members of, participants in, the Depositary (the “Agent Members”) holding the Securities evidenced thereby, registered with the Depositary for credit to the accounts of the Agent Members then holding such Securities on behalf of Euroclear or Clearstream, as applicable);

(3) bear the Restricted Securities Legend set forth in Section 2.3(a)(i).

Agent Members shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Trustee or any agent of the Company or Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and the Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. With respect to any Global Security deposited on behalf of the subscribers for the Securities represented thereby with the Trustee as custodian for the Depositary for credit to their respective accounts (or to such other accounts as they may direct) at Euroclear or Clearstream, the provisions of the “Operating Procedures of the Euroclear System” and the “Terms and Conditions Governing Use of Euroclear” and the “Management Regulations” and “Instructions to Participants” of Clearstream, respectively, shall be applicable to the Global Securities.

(b) The registered Holder of a Global Security 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 this Indenture or the Securities.

(c) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary, and no such transfer to any such other Person may be registered. Beneficial interests in a Global Security may be transferred in accordance with the rules and procedures of the Depositary and the provisions of Section 2.9 hereof.

(d) If at any time:

(1) the Depositary notifies the Company in writing that it is no longer willing or able to continue to act as Depositary for the Global Securities, or the Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary for the Global Securities is not appointed by the Company within 90 days of such notice or cessation;

(2) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Physical Securities under this Indenture in exchange for all or any part of the Securities represented by a Global Security or Global Securities; or

(3) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary for the issuance of Physical Securities in exchange for such Global Security or Global Securities,

then the Depositary shall surrender such Global Security or Global Securities to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and Company Order for the authentication and delivery of Securities (which certificate and order the Company shall promptly deliver to the Trustee), shall authenticate and deliver in exchange for such Global Security or Global Securities, Physical Securities in an aggregate principal amount equal to the aggregate principal amount of such Global Security or Global Securities. Such Physical Securities shall be registered in such names as the Depositary shall identify in writing as the beneficial owners of the Securities represented by such Global Security or Global Securities (or any nominee thereof).

(e) In connection with any transfer of beneficial interests in a Global Security to the beneficial owners thereof pursuant to Section 2.8(d) hereof, the Registrar shall reflect on its books and records the date and a decrease in the aggregate principal amount of such Global Security in an amount equal to the aggregate principal amount of the beneficial interest in such Global Security to be transferred in the form of Physical Securities.

Section 2.9. Transfer Provisions.

Unless a Security is (i) transferred after the time period referred to in Rule 144(k) under the Securities Act or (ii) sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such sale), the following provisions shall apply to any sale, pledge or other transfer of Securities:

(a) Transfers of securities to an Institutional Accredited Investor that is not a QIB.

The following provisions shall apply with respect to the registration of any proposed transfer of Securities to an Institutional Accredited Investor that is not a QIB:

(i) The Registrar shall register the transfer if the proposed transferee has delivered to the Trustee (A) a certificate substantially in the form of Exhibit F annexed hereto and (B) such opinion of counsel and other evidence satisfactory to the Company that such transfer is in compliance with the Securities Act, as requested by the Company.

(ii) If the proposed transferor is an Agent Member holding a beneficial interest in Global Securities, upon receipt by the Registrar of the documents required by clause (i) of this Section 2.9(a) and instructions given in accordance with the procedures of Euroclear or Clearstream, if applicable, the Depositary and the Registrar, the Registrar shall reflect on its books and records, and Euroclear or Clearstream, if applicable, or the Registrar shall instruct the Depositary to note or cause to be noted on such Global Securities, the date and a decrease in the principal amount of the Global Securities in an amount equal to the principal amount of the beneficial interest in the Global Securities to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Securities of like tenor and amount registered in the name of the transferee.

(iii) If the Securities to be transferred consist of Physical Securities, upon receipt by the Registrar of the documents required by clause (i) of this Section 2.9(a), the Company shall execute and the Trustee shall authenticate and deliver, new Physical Securities registered in the name of the transferee and the Trustee shall cancel the Physical Securities presented for transfer.

(b) Transfer of Securities to a QIB.

The following provisions shall apply with respect to the registration of any proposed transfer of Securities to a QIB:

(i) If the Securities to be transferred consist of a beneficial interest in the Global Securities, the transfer of such interest may be effected only through the book-entry systems maintained by Euroclear and Clearstream, if applicable, and the Depositary.

(ii) If the Securities to be transferred consist of Physical Securities, the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Security stating (or has otherwise advised the Company and the Registrar in writing) that the sale has been made:

in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Security stating or has otherwise advised the Company and the Registrar in writing that:

(1) it is purchasing the Securities for its own account or an account with respect to which it exercises sole investment discretion, in each case for investment and not with a view to distribution;

(2) it and any such account is a QIB within the meaning of Rule 144A;

(3) it is aware that the sale to it is being made in reliance on Rule 144A;

(4) it acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information; and

(5) it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

In addition, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Securities in an amount equal to the aggregate principal amount of the Physical Securities to be transferred, and the Trustee shall cancel the Physical Securities so transferred.

In the event that Global Securities are exchanged for Securities in definitive registered form pursuant to Section 2.8 prior to the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with the provisions of clauses (a) and (b) above (including the certification requirements intended to ensure that such transfers comply with Rule 144A) and such other procedures as may from time to time be adopted by the Company consistent with the provisions of Section 2.3 and the legends set forth therein.

(d) General.

By its acceptance of any Security or shares of Common Stock issuable upon conversion of the Securities bearing the Restricted Securities Legend, each Holder of such Security or shares of Common Stock acknowledges the restrictions on transfer of such Security or shares of Common Stock set forth in this Indenture and agrees that it will transfer such Security and such Common Stock only as provided in this Indenture. The Registrar shall not register a transfer of any Security unless such transfer complies with the restrictions on transfer of such Security set forth in this Indenture. The Registrar shall be entitled to receive and conclusively rely on written instructions from the Company verifying that such transfer complies with such restrictions on transfer. In connection with any transfer of Securities, each Holder agrees by its acceptance of the Securities to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar 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.

The Registrar shall retain copies of all certifications, letters, notices and other written communications received pursuant to Section 2.8 hereof or this Section 2.9 in accordance with its customary procedures for the retention of records relating to the transfer of securities. 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 Registrar.

Section 2.10. Holder 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 Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish to the Trustee prior to or on each Interest Payment Date 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 Holders relating to such Interest Payment Date or request, as applicable.

Section 2.11. Persons Deemed Owners.

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of the Security or the payment of any Redemption Price or Repurchase Price in respect thereof and Interest (including Contingent Interest) thereon, if any, for any purpose under this Indenture, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12. Mutilated, Destroyed, Lost or Stolen Securities.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and aggregate principal amount and bearing a number not contemporaneously outstanding.

If there is delivered to the Company and the Trustee

(1) evidence to their satisfaction of the destruction, loss or theft of any Security, and

(2) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of actual notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon request, the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security, upon satisfaction of the condition set forth in the preceding paragraph.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security issued pursuant to this Section 2.12 in lieu of any destroyed, lost or stolen Security shall constitute an original contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section 2.12 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 2.13. Treasury Securities.

In determining whether the Holders of the requisite principal amount of Outstanding Securities are present at a meeting of Holders for quorum purposes or have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any Affiliate of the Company shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such determination as to the presence of a quorum or upon any such request, demand, authorization, direction, notice, consent or waiver, only such Securities of which a Responsible Officer of the Trustee has received written notice and are so owned shall be so disregarded.

Section 2.14. Temporary Securities.

Pending the preparation of Securities in definitive form, the Company may execute and the Trustee shall, upon written request of the Company, authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination, and substantially in the form of the Securities in definitive form but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Securities in definitive form. Without unreasonable delay, the Company will execute and deliver to the Trustee Securities in definitive form (other than in the case of Securities in global form) and thereupon any or all temporary Securities (other than any such Securities in global form) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 9.2 and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal principal amount of Securities in definitive form. Such exchange shall be made by the Company

at its own expense and without any charge therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Securities in definitive form authenticated and delivered hereunder.

Section 2.15. Cancellation.

All Securities surrendered for payment, redemption, purchase, conversion, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered shall be canceled promptly by the Trustee, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. Upon written instructions of the Company, the Trustee shall dispose of canceled Securities in accordance with its procedures for the disposition of cancelled securities in effect as of the date of such disposition. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless the same are delivered to the Trustee for cancellation.

Section 2.16. CUSIP Numbers.

The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and the Trustee shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice shall state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any such notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

Section 2.17. Defaulted Interest.

If the Company fails to make a payment of principal, Redemption Price, Repurchase Price or Interest (including Contingent Interest) on any CODES when due and payable, it shall pay Interest (including Contingent Interest) on such amounts (to the extent lawful), which shall be calculated using the applicable Interest Rate (such amounts, the “Defaulted Interest”). The Company may elect to pay such Defaulted Interest, plus any other Interest (including Contingent Interest) payable on it, to the Persons who are Holders on which the Interest (including Contingent Interest) is due on a subsequent special record date. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such CODES. The Company shall fix any such special record date and payment date for such payment. At least 15 days before any such special record date, the Company shall mail to Holders affected thereby a notice that states the special record date, the Interest Payment Date and amount to be paid.

ARTICLE 3

DISCHARGE OF INDENTURE

Section 3.1. Discharge of Liability on Securities. When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.12) for cancellation or (ii) all outstanding Securities have become due and payable at their Stated Maturity or all outstanding Securities have been redeemed and the Company has deposited with the Trustee cash or, in the event of conversions pursuant to Article 12, Common Stock, sufficient to pay all amounts and deliver all Common Stock due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.12) on the date of their Stated Maturity or the Redemption Date, as the case may be, and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 5.8, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and Opinion of Counsel and at the cost and expense of the Company.

Section 3.2. Repayment to the Company.

The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Holders with respect to such money or securities for that period commencing after the return thereof.

ARTICLE 4

DEFAULTS AND REMEDIES

Section 4.1. Events of Default.

An “Event of Default”, wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(a) the Company defaults in converting the CODES into shares of Common Stock upon exercise of a Holder’s conversion right;

(b) the Company defaults in the payment of the principal amount, Redemption Price or Repurchase Price (each, a “Defaulted Payment”) on any Outstanding CODES when the same becomes due and payable at its Stated Maturity, upon redemption, repurchase, upon declaration, when due for purchase by the Company or otherwise;

(c) the Company defaults in the payment of an installment of Interest (including Contingent Interest) on any CODES when it becomes due and payable and such default continues for a period of 30 days;

(d) the Company fails to pay Additional Amounts, if any, with respect to any of the CODES for 30 days after the date when due;

(e) the Company fails to perform or observe any other term, covenant or agreement contained in the Securities or this Indenture and the default continues for a period of 60 days after written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding CODES;

(f) the Company defaults under any indebtedness for money borrowed by the Company, any Guarantor or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, the aggregate outstanding principal amount of which is in an amount in excess of $25.0 million, for a period of 30 days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the Outstanding CODES, which default (i) is caused the Company’s failure to pay when due principal or interest on such indebtedness by the end of the applicable grace period, if any, unless such indebtedness is discharged or (ii) results in the acceleration of such indebtedness, unless such acceleration is waived, cured, rescinded or annulled; and

(g) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company, in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company, under any applicable U.S. federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days;

(h) the commencement by the Company of a voluntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, to the entry of a decree or order for relief in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, of a petition or answer or consent seeking reorganization or relief under any applicable U.S. federal or state law, or the consent by the Company to the filing of such petition or to the appointment of or the taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or the making by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, of an assignment for the benefit of creditors, or the admission by the Company or any of its

(i) except in accordance with Section 13.3 hereof, any Guarantee shall be held in any judicial proceeding to be unenforceable or invalid.

A Default under clause (e) or (f) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% of the principal amount of the CODES at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (e) or (f) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

The Trustee shall, within 90 days of the occurrence of a Default, give to the Holders of the Securities notice of all uncured Defaults known to it and written notice of any event which with the giving of notice or the lapse of time, or both, would become an Event of Default; provided, however, the Trustee shall be protected in withholding such notice if it, in good faith, determines that the withholding of such notice is in the best interest of such Holders, except in the case of a Default in the payment of the Principal of or Interest (including Contingent Interest) on, any of the Securities when due or in the payment of any redemption or Repurchase Right.

Section 4.2. Acceleration of Maturity; Rescission and Annulment.

If an Event of Default with respect to Outstanding CODES (other than an Event of Default specified in Section 4.1(g) or 4.1(h) hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding CODES, by written notice to the Company, may declare due and payable 100% of the principal amount of all Outstanding CODES, plus any accrued and unpaid Interest (including Contingent Interest), to the date of payment. Upon a declaration of acceleration, such principal amount, and accrued and unpaid Interest (including Contingent Interest) to the date of payment shall be immediately due and payable. If an Event of Default specified in Section 4.1(g) and 4.1(h) occurs, the principal, and accrued and unpaid Interest (including Contingent Interest) on the Outstanding CODES shall become and be immediately due and payable. Once the principal and accrued and unpaid Interest (including Contingent Interest) on the Outstanding CODES shall become and be immediately due and payable, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders at appropriate judicial proceedings.

Section 4.3. Other Remedies.

If an Event of Default with respect to Outstanding CODES occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the Defaulted Payment or Interest (including Contingent Interest) due and payable on the CODES or to enforce the performance of any provision of the Securities.

The Trustee may maintain a proceeding in which it may prosecute and enforce all rights of action and claims under this Indenture or the Securities, even if it does not possess any of the Securities or does not produce any of them in the proceeding.

Section 4.4. Waiver of Past Defaults.

The Holders, either (a) through the written consent of not less than a majority of the principal amount of the Outstanding CODES, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding CODES at which a quorum is present, by the Holders of at least a majority of the principal amount of the Outstanding CODES represented at such meeting, may, on behalf of the Holders of all of the CODES, waive an existing Default or Event of Default, except a Default or Event of Default:

(1) set forth in Sections 4.1(a), (b) and (c), provided, however, that subject to Section 4.7, the Holders of a majority of the principal amount of the Outstanding CODES may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration; or

(2) in respect of a covenant or provision hereof which, under Section 7.2 hereof, cannot be modified or amended without the consent of the Holders of each Outstanding CODES affected;

provided that any such waiver or rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under Section 4.1(f) and the default with respect to Indebtedness for money borrowed which gave rise to such Event of Default has been remedied, cured or waived, then, without any further action by the Holders, such declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon; and provided, further, that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 4.5. Control by Majority.

The Holders of a majority of the principal amount of the Outstanding CODES (or such lesser amount as shall have acted at a meeting pursuant to the provisions of this Indenture) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that:

(1) conflicts with any law or with this Indenture;

(2) the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein; or

(3) may expose the Trustee to personal liability.

The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 4.6. Limitation on Suit.

No Holder of any Security shall have any right to pursue any remedy with respect to this Indenture or the Securities (including, instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee) unless:

(1) such Holder has previously given written notice to the Trustee of an Event of Default that is continuing;

(2) the Holders of at least 25% of the principal amount of the Outstanding CODES shall have made written request to the Trustee to pursue the remedy;

(3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against any costs, expenses and liabilities incurred in complying with such request;

(4) the Trustee has failed to comply with the request for 60 days after its receipt of such notice, request and offer of indemnity; and

(5) during such 60-day period, no direction inconsistent with such written request has been given to the Trustee by the Holders of a majority of the principal amount of the Outstanding CODES (or such amount as shall have acted at a meeting pursuant to the provisions of this Indenture);

provided, however, that no one or more of such Holders may use this Indenture to prejudice the rights of another Holder or to obtain preference or priority over another Holder.

Section 4.7. Unconditional Rights of Holders to Receive Payment and to Convert.

Notwithstanding any other provision in this Indenture, the Holder of any CODES shall have the right, which is absolute and unconditional, to receive payment of the principal amount, Redemption Price or Repurchase Price, and Interest (including Contingent Interest) in respect of the CODES held by such Holder, on or after the respective due dates expressed in the CODES or any Redemption Date or Repurchase Date, and to convert the CODES in accordance with Article 12, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, and such rights shall not be impaired or affected adversely without the consent of such Holder.

Section 4.8. Collection of Indebtedness and Suits for Enforcement by the Trustee.

The Company covenants that if:

(1) a Default or Event of Default is made in the payment of Interest (including Contingent Interest) on any CODES when such Interest (including Contingent Interest) becomes due and payable and such Default or Event of Default continues for a period of 30 days; or

(2) a Default or Event of Default is made in the payment of the principal amount, Redemption Price or Repurchase Price on any CODES when the same becomes due and payable at its Stated Maturity, upon redemption, upon declaration when due for purchase by the Company or otherwise,

then the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such CODES, the entire principal then due and payable (as expressed therein or as a result of any acceleration effected pursuant to Section 4.2 hereof) on such CODES for any such amounts and, to the extent legally enforceable, Interest (including Contingent Interest) on such CODES, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 4.9. Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the principal amount, Redemption Price, Repurchase Price or Interest (including Contingent Interest) in respect of the CODES shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(1) to file and prove a claim for the whole amount of the principal amount, Redemption Price, Repurchase Price or Interest (including Contingent Interest) owing and unpaid in respect of the CODES and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of CODES allowed in such judicial proceeding and

(2) to collect and receive any monies, Common Stock or other property payable or deliverable on any such claim and to distribute the same,

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceedings is hereby authorized by each Holder of CODES to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of CODES, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 5.8.

Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept, or adopt on behalf of any Holder of a CODES, any plan of reorganization, arrangement, adjustment or composition affecting the CODES or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a CODES in any such proceeding.

Section 4.10. Restoration of Rights and Remedies.

If the Trustee or any Holder of a CODES has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of CODES shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 4.11. Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.12, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 4.12. Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as applicable.

Section 4.13. Priorities.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee:

FIRST: to the payment of all amounts due to the Trustee under Section 5.8;

SECOND: to Holders for amounts due and unpaid on the Securities for the principal amount, Redemption Price, Repurchase Price or Interest (including Contingent Interest) as applicable, ratably, without preference or priority of any kind, according to such amounts due and payable on the CODES; and

THIRD: any remaining amounts shall be repaid to the Company.

The Trustee may fix a special record date and payment date for any payment to Holders pursuant to this Section 4.13. At least 15 days before such special record date, the Trustee shall mail to each Holder and the Company a notice that states the special record date, the payment date and the amount to be paid.

Section 4.14. Undertaking for Costs.

All parties to this Indenture agree, and each Holder of any CODES by such Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the principal amount of the Outstanding CODES, or to any suit instituted by any Holder of any CODES for the enforcement of (i) payments pursuant to Section 4.7 repurchase rights in accordance with Article 11 or (ii) conversion rights in accordance with Article 12. This Section 4.14 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 4.15. Waiver of Stay or Extension Laws.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force,

which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 5

THE TRUSTEE

Section 5.1. Certain Duties and Responsibilities.

(a) Except during the continuance of an Event of Default,

(1) The Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture or the TIA, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, that in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates or opinions to determine whether or not, on their face, they conform to the requirements to this Indenture (but need not investigate or confirm the accuracy of any facts stated therein).

(b) In case an Event of Default actually known to a Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) This paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section 5.1;

(2) The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and

(3) The Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with a direction received by it of the Holders of a majority of the principal amount of the Outstanding

Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of this Indenture) relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

(d) Whether or not herein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 5.1.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity reasonably satisfactory to it against any loss, liability, cost or expense (including, without limitation, reasonable fees and expenses of counsel).

(f) The Trustee shall not be obligated to pay interest on any money or other assets received by it unless otherwise agreed in writing with the Company. Assets held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(h) The Trustee shall not be deemed to have notice or actual knowledge of any Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact a Default is received by the Trustee pursuant to Section 14.2 hereof, and such notice references the Securities and this Indenture.

(i) The rights, privileges, protections, immunities and benefits given to the Trustee hereunder, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent, authenticating agent, Calculation Agent, Conversion Agent or Registrar acting hereunder.

(j) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

Section 5.2. Certain Rights of Trustee.

Subject to the provisions of Section 5.1 hereof and subject to Section 315(a) through (d) of the TIA:

(1) The Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(2) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel, or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

(3) The Trustee may act through attorneys and agents and shall be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

(6) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

(7) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.

Section 5.3. Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in Section 310(b) of the TIA), it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee (to the extent permitted under Section 310(b) of the TIA) or resign. Any agent may do the same with like rights and duties. The Trustee is also subject to Sections 5.11 and 5.12 hereof.

Section 5.4. Money Held in Trust.

Money held by the Trustee in trust hereunder shall not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise expressly agreed in writing with the Company.

Section 5.5. Trustee’s Disclaimer.

The recitals contained herein and in the Securities (except for those in the certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.

Section 5.6. Notice of Defaults.

Within 90 days after the occurrence of any Default or Event of Default hereunder of which the Trustee has received written notice, the Trustee shall give notice to Holders, unless such Default or Event of Default shall have been cured or waived; provided, however, that, except in the case of a Default or Event of Default described in Sections 4.1(a) or (b), the Trustee shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders. The second sentence of this Section 5.6 shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a Responsible Officer of the Trustee has received written notice of such Default.

Section 5.7. Reports by Trustee to Holders.

The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required by Section 313 of the TIA at the times and in the manner provided by the TIA. If required by Section 313(a) of the TIA, the Trustee shall, within 60 days after each September 15 following the date of this Indenture deliver to Holders a brief report, dated as of such September 15, which complies with the provisions of such Section 313(a).

A copy of each report at the time of its mailing to Holders shall be filed with the Commission, if required, and each stock exchange, if any, on which the Securities and the Common Stock are listed. The Company shall promptly notify the Trustee when the Securities or the Common Stock become listed on any stock exchange and of any delisting thereof.

Section 5.8. Compensation and Indemnification.

The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as agreed to in writing by the Trustee and the Company (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including

the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ), except to the extent that any such expense, disbursement or advance is due to its negligence or bad faith. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.1, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any bankruptcy law. The Company also covenants to indemnify the Trustee and its officers, directors, employees and agents for, and to hold such Persons harmless against, any loss, liability or expense incurred by them, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder or the performance of their duties hereunder, including the costs and expenses of defending themselves against or investigating any claim (whether asserted by the Company, a Guarantor, a Holder or any other Person) of liability in the premises, except to the extent that any such loss, liability or expense was due to the negligence or willful misconduct of such Persons. The obligations of the Company under this Section 5.8 to compensate and indemnify the Trustee and its officers, directors, employees and agents and to pay or reimburse such Persons for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee. Such additional indebtedness shall be a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such senior claim. “Trustee” for purposes of this Section 5.8 shall include any predecessor Trustee, but the negligence or willful misconduct of any Trustee shall not affect the indemnification of any other Trustee.

Section 5.9. Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 5.9.

The Trustee may resign and be discharged from the trust hereby created by so notifying the Company in writing. The Holders of at least a majority of the principal amount of Outstanding CODES may remove the Trustee by so notifying the Trustee and the Company in writing. The Company must remove the Trustee if:

(i) the Trustee fails to comply with Section 5.11 hereof or Section 310 of the TIA;

(ii) the Trustee becomes incapable of acting;

(iii) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; or

(iv) a Custodian or public officer takes charge of the Trustee or its property.

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint a successor Trustee. The Trustee shall be entitled to payment of its fees and reimbursement of its expenses while acting as

Trustee. Within one year after the successor Trustee takes office, the Holders of at least a majority of the principal amount of Outstanding CODES may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

Any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee if the Trustee fails to comply with Section 5.11.

If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or removal, the resigning or removed Trustee, as applicable, may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Company shall issue a notice of the successor Trustee’s succession to the Holders. Upon payment of its charges, the retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject nevertheless to its lien, if any, provided for in Section 5.8 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 5.9 hereof, the Company’s obligations under Section 5.8 hereof shall continue for the benefit of the retiring Trustee with respect to expenses, losses and liabilities incurred by it prior to such replacement.

Section 5.10. Successor Trustee by Merger, Etc.

Subject to Section 5.11 hereof, if the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking association, the successor entity without any further act shall be the successor Trustee as to the Securities.

Section 5.11. Corporate Trustee Required; Eligibility.

The Trustee shall at all times satisfy the requirements of Section 310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have (or, in the case of a corporation included in a bank holding company system, the related bank holding company shall at all times have), a combined capital and surplus of at least $50 million as set forth in its (or its related bank holding company’s) most recent published annual report of condition. The Trustee is subject to Section 310(b) of the TIA.

Section 5.12. Collection of Claims Against the Company.

The Trustee is subject to Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

ARTICLE 6

CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

Section 6.1. Company May Consolidate, Etc., Only on Certain Terms.

The Company shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, and the Company shall not permit any Person to consolidate with or merge into the Company or convey, transfer or lease its properties and assets substantially as an entirety to the Company, unless:

(1) in the event that the Company shall consolidate with or merge into another Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, the Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Company substantially as an entirety shall be a corporation organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia;

(2) in the event that the Company shall consolidate with or merge into another Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, and the entity surviving such transaction or transferee entity is not the Company, then such surviving or transferee entity shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, the due and punctual payment of all and any amounts when due on all the CODES and the performance of every covenant of this Indenture and the CODES on the part of the Company to be performed or observed and shall have provided for conversion rights provided in Article 12;

(3) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and

(4) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with.

Section 6.2. Successor Corporation Substituted.

Upon any consolidation or merger by the Company with or into any other corporation or any conveyance, transfer or lease of the properties and assets of the Company

substantially as an entirety to any Person, in accordance with Section 6.1 hereof, the successor corporation formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor corporation had been named as the Company herein. In the event of any such conveyance or transfer, the Company (which term shall for this purpose mean the Person named as the “Company” in the first paragraph of this Indenture or any successor Person which shall theretofore become such in the manner described in Section 6.1 hereof), except in the case of a lease to another Person, the predecessor corporation shall be relieved of all obligations and covenants under this Indenture and the Securities and may be dissolved and liquidated.

ARTICLE 7

(b) There shall be no purchase of any CODES pursuant to Section 11.1(a) or 11.1(b) if there has occurred (prior to, on or after, as applicable, the giving, by the Holders of such CODES, of the required Repurchase Notice) and is continuing an Event of Default (other than a default in the payment of the Repurchase Price with respect to such CODES). The Paying Agent will promptly return to the respective Holders thereof any CODES (x) with respect to which a Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Repurchase Price with respect to such Securities) in which case, upon such return, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

(c) If any CODES delivered for purchase pursuant to Section 11.1(a) or 11.1(b) shall not be so paid on the Repurchase Date, the principal amount of such CODES shall, until it is paid, bear Interest (including Contingent Interest) from the purchase date to but not including the date of actual payment hereunder at the applicable Interest Rate, and each such CODES shall remain convertible into shares of Common Stock pursuant to Article 12 until such CODES shall have been paid.

CODES in respect of which a Repurchase Notice has been delivered by the Holder thereof may not be converted pursuant to Article 12 on or after the date of the delivery of such Repurchase Notice unless such Repurchase Notice which has been completed and delivered to the Paying Agent has first been validly withdrawn pursuant to Section 11.3(c).

(b) All CODES delivered for purchase shall be canceled by the Trustee or Paying Agent, as applicable.

Section 11.7. Physical Securities Purchased in Part.

Any Physical Security which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such CODES, without service charge, new CODES, of any authorized denomination as requested by such Holder in principal amount equal to, and in exchange for, the portion of the principal amount of the CODES so surrendered which is not purchased.

ARTICLE 12

CONVERSION OF SECURITIES

Section 12.1. Conversion Privilege.

(a) Subject to and upon compliance with the provisions of this Article, at the option of the Holder, any CODES or any portion of the principal amount thereof which is an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into duly authorized, fully paid and nonassessable shares of Common Stock, at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion:

(1) during any fiscal quarter, if the Sale Price of the Common Stock for at least 20 Trading Days in the 30 consecutive Trading-Day period ending on the last day of the preceding fiscal quarter was more than 130% of the Conversion Price on that thirtieth Trading Day;

(2) on or before December 15, 2028, during the five Business Day period following any 10 consecutive Trading-Day period in which the average of the Trading Prices for the CODES, as determined following a written request by a Holder of CODES delivered to the Company in accordance with Section 14.2, to make a determination, for that 10 Trading-Day period was less than 98% of the average Conversion Value for the CODES during such period;

(3) during any period, following the date the CODES are rated by both Moody’s and by Standard and Poor’s, (1) when the credit ratings assigned to the CODES by Xxxxx’x is lower than “Ba3” or by Standard & Poor’s is lower than “BB”, (2) in which the credit rating assigned to the CODES is suspended or withdrawn by either rating agency, or (3) in which neither agency continues to rate the CODES or provide ratings services or coverage to the Company;

(4) if the Company has called the CODES for redemption; or

(5) upon the occurrence of the corporate transactions specified in clause (b) of this Section 12.1.

The Company shall determine on a daily basis whether the CODES shall be convertible as a result of the occurrence of an event specified in clause (1) or, following a request by a Holder of CODES delivered to the Company, clause (2) above and, if the CODES shall be so convertible, the Company shall promptly deliver to the Trustee written notice thereof. Whenever the CODES shall become convertible pursuant to Section 12.1, the Company or, at the Company’s written request, the Trustee in the name and at the expense of the Company, shall notify the Holders of the event triggering such convertibility in the manner provided in Section 14.2, and the Company shall also publicly announce such information and publish it on the Company’s web site. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

Notwithstanding anything to the contrary contained herein, the Conversion Agent shall have no obligation to determine the Trading Price of the CODES pursuant to clause (2) above, unless the Company shall have requested that it make such determination; and the Company shall have no obligation to make such request unless so requested by a Holder. At such time as a written request is made by a Holder, the Company shall instruct the Conversion Agent to determine the Trading Price per CODES beginning on the next trading day and on each successive Trading Day until the Trading Price per CODES is greater than or equal to 98% of the average Conversion Value for 10 consecutive days.

(b) In addition, in the event that:

(1) (A) the Company distributes to all or substantially all holders of its shares of Common Stock rights or warrants entitling them (for a period expiring within 60 days of the Record Date for such distribution) to subscribe for or purchase shares of Common Stock, at a price per share less than the Trading Price of the Common Stock on the Business Day immediately preceding the announcement of such distribution, (B) the Company distributes to all or substantially all holders of its shares of Common Stock, cash or other assets, debt securities or rights or warrants to purchase its securities, where the Fair Market Value (as determined by the Board of Directors) of such distribution per share of Common Stock exceeds 5% of the Trading Price of a share of Common Stock on the Business Day immediately preceding the date of declaration of such distribution, or (C) a Change of Control occurs but Holders of CODES do not have the right to require the Company to purchase their CODES as a result of such Change of Control because either (i) the Trading Price of the Common Stock for specified periods (as described in the definition of Change of Control) exceeds specified levels (as described in the definition of Change of Control) or (ii) the consideration received in such Change of Control consists of Capital Stock that is freely tradeable and the CODES become convertible into that Capital Stock as specified in the definition of Change of Control, then, in each case, the CODES may be surrendered for conversion at any time on and after the date that the Company gives notice to the Holders of such right, which shall be not less than 20 days prior to the Ex-Dividend Time for such distribution, in the case of (A) or (B), or within 30 days after the occurrence of the Change of Control, in the case of (C), until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Time or the date the Company announces that such distribution will not take place, in the case of (A) or (B), or the earlier of 30 days after the Company’s delivery of the Repurchase Notice for Change of Control Repurchase Rights or the date the Company announces that the Change of Control will not take place, in the case of (C), or

(2) the Company consolidates with or merges into another corporation, or is a party to a binding share exchange pursuant to which the shares of Common Stock would be converted into cash, securities or other property as set forth in Section 12.4 hereof, then the CODES may be surrendered for conversion at any time from and after the date which is 15 days prior to the date announced by the Company as the anticipated effective time of such transaction until 15 days after the actual date of such transaction.

The Conversion Rate, at any time, shall equal (A) $1,000 divided by the Conversion Price at such time, rounded to three decimal places (rounded up if the fourth decimal place thereof is 5 or more and otherwise rounded down).

Section 12.2. Conversion Procedure; Conversion Price; Fractional Shares.

(a) Each CODES shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares (calculated to the nearest 1/100th of a share) of Common Stock. The CODES will be converted into shares of Common Stock at the Conversion Price therefor. No payment or adjustment shall be made in respect of dividends on the Common Stock or accrued interest on a converted CODES, except as described in Section 12.9 hereof. The Company shall not issue any fraction of a share of Common Stock in connection with any conversion of CODES, but instead shall, subject to Section 12.3(h) hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Sale Price of the Common Stock on the last Trading Day prior to the date of conversion. Notwithstanding the foregoing, a CODES in respect of which a Holder has delivered a Repurchase Notice exercising such Holder’s option to require the Company to repurchase such CODES may be converted only if such notice of exercise is withdrawn in accordance with Section 11.3 hereof.

(b) Before any Holder of a CODES shall be entitled to convert the same into Common Stock, such Holder shall, in the case of CODES issued in global form, comply with the procedures of the Depositary in effect at that time, and in the case of Physical Securities, surrender such CODES, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place that such Holder elects to convert the same and shall state in writing therein the principal amount of CODES to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued.

Before any such conversion, a Holder also shall pay all funds required, if any, relating to interest on the CODES, as provided in Section 12.9, and all taxes or duties, if any, as provided in Section 12.8.

If more than one CODES shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be deliverable upon conversion shall be computed on the basis of the aggregate principal amount of the CODES (or specified portions thereof to the extent permitted thereby) so surrendered. Subject to the next succeeding sentence, the Company will, as soon as practicable thereafter, issue and deliver at said office or place to such Holder of a CODES, or to such Holder’s nominee or nominees, certificates for the number of full shares of Common Stock to which such Holder shall be entitled as aforesaid, together, subject to the last sentence of Section 12.2(a) above, with cash in lieu of any fraction of a share to which such Holder would otherwise be entitled. The Company shall not be required to deliver certificates for shares of Common Stock while the stock transfer books for such stock or the security register are duly closed for any purpose, but certificates for shares of Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register.

(c) A CODES shall be deemed to have been converted as of the close of business on the date of the surrender of such CODES for conversion as provided above and the satisfaction of the other requirements for conversion, and the person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such Common Stock as of the close of business on such date.

(d) In case any CODES shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the CODES so surrendered, without charge to such Holder (subject to the provisions of Section 12.8 hereof), new CODES in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered CODES.

Section 12.3. Adjustments of Conversion Price for Common Stock.

The Conversion Price shall be adjusted from time to time as follows:

(a) In case the Company shall, at any time or from time to time while any of the CODES are outstanding, pay a dividend or make a distribution in shares of Common Stock to all holders of its outstanding shares of Common Stock, then the Conversion Price in effect at the opening of business on the date following the record date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction:

(1) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date fixed for such determination; and

(2) the denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution.

Such reduction shall become effective immediately after the opening of business on the day following the Record Date fixed for such determination. If any dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall, at any time or from time to time while any of the CODES are outstanding, subdivide its outstanding shares of Common Stock into a greater number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case the Company shall, at any time or from time to time while any of the CODES are outstanding, combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased.

Such reduction or increase, as the case may be, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(c) In case the Company shall, at any time or from time to time while any of the CODES are outstanding, issue rights or warrants (other than any rights or warrants referred to in Section 12.3(d)) to all or substantially all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) at a price per share (or having a conversion price per share) less than the Sale Price on the Business Day immediately preceding the date of the announcement of such issuance (treating the conversion price per share of the securities convertible into Common Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into Common Stock and (ii) any additional consideration initially payable upon the conversion of such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible security), then the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such date of announcement by a fraction:

(1) the numerator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares or securities which the aggregate offering price of the total number of shares or securities so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Sale Price of the Common Stock; and

(2) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible).

Such adjustment shall become effective immediately after the opening of business on the day following the date of announcement of such issuance. To the extent that shares of Common Stock (or securities convertible into shares of Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into shares of Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors.

(d) In case the Company shall, at any time or from time to time while any of the CODES are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the Common Stock is not changed or exchanged), cash, shares of its capital stock (other than any dividends or

distributions to which Section 12.3(a) applies), evidences of its Indebtedness or other assets, including securities, but excluding (i) any rights or warrants referred to in Section 12.3(c), (ii) dividends or distributions of stock, securities or other property or assets (including cash) in connection with a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies and (iii) dividends and distributions paid exclusively in cash (such capital stock, evidence of its indebtedness, cash, other assets or securities being distributed hereinafter in this Section 12.3(d) called the “distributed assets”), then, in each such case, subject to the third and fourth succeeding paragraphs and the last Section of this Section 12.3(d), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction:

(1) the numerator of which shall be the Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Record Date) (determined as provided in Section 12.3(g)) on such date; and

(2) the denominator of which shall be such Current Market Price.

Such reduction shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 12.3(g) to the extent possible, unless the Board of Directors determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders.

In the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the Company’s Subsidiaries (a “Spin-Off”), the Fair Market Value of the securities to be distributed shall equal the average of the closing sale prices of such securities on the principal securities market on which such securities are traded for the five consecutive Trading Days commencing on and including the sixth day of trading of those securities after the effectiveness of the Spin-Off, and the Current Market Price shall be measured for the same period. In the event, however, that an underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities and the Current Market Price shall mean the Sale Price for the Common Stock on the same Trading Day.

Rights or warrants distributed by the Company to all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”), (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are also issued in respect of future issuances of shares of Common Stock shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the Conversion Price under this Section 12.3(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 12.3(d):

(1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of shares of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of shares of Common Stock as of the date of such redemption or repurchase; and

(2) in the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued.

For purposes of this Section 12.3(d) and Sections 12.3(a), 12.3(b) and 12.3(c), any dividend or distribution to which this Section 12.3(d) is applicable that also includes (i) shares of Common Stock, (ii) a subdivision or combination of shares of Common Stock to which Section 12.3(b) applies or (iii) rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.3(c) applies (or any combination thereof), shall be deemed instead to be:

(1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Sections 12.3(a), 12.3(b) and 12.3(c) apply, respectively (and any Conversion Price reduction required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by

(2) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Price reduction required by Sections 12.3(a), 12.3(b) and 12.3(c) with respect to such dividend or distribution shall then be made), except:

(A) the Record Date of such dividend or distribution shall be substituted as (i) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of Section 12.3(a), (ii) “the day upon which such subdivision becomes effective” and “the day upon which such combination becomes effective” within the meaning of Section 12.3(b), and (iii) as “the date fixed for the determination of stockholders entitled to receive such rights or warrants,” “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 12.3(c); and

(B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 12.3(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

In the event of any distribution referred to in this Section 12.3(d) in which (1) the Fair Market Value (as determined by the Board of Directors) of such distribution applicable to one share of Common Stock (determined as provided above) equals or exceeds the average of the Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Record Date for such distribution or (2) the average of the Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Record Date for such distribution exceeds the Fair Market Value of such distribution by less than $1.00, then, in each such case, in lieu of an adjustment to the Conversion Price, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a CODES, in addition to shares of Common Stock, the kind and amount of such distribution such Holder would have received had such Holder converted such CODES immediately prior to the Record Date for determining the shareholders entitled to receive the distribution.

In the event of any distribution referred to in Section 12.3(c) or 12.3(d), where, in the case of a distribution described in Section 12.3(d), the Fair Market Value of such distribution per share of Common Stock (as determined by the Board of Directors) exceeds 5% of the Sale Price of a share of Common Stock on the Business Day immediately preceding the declaration date for such distribution, then, if such distribution would also trigger a conversion right under Section 12.1(b) or the CODES are otherwise convertible pursuant to this Article 12, the Company will be required to give notice to the Holders of CODES at least 20 days prior to the Ex-Dividend Time for the distribution and, upon the giving of notice, the CODES may be surrendered for conversion at any time on and after the date that the Company gives notice to the Holders of such conversion right, until the close of business on the Business Day prior to the Ex-Dividend Time or the Company announces that such distribution will not take place. No adjustment to the Conversion Price or the ability of a Holder of a CODES to convert will be made if the Holder will otherwise participate in such distribution without conversion.

(e) In case the Company shall, at any time or from time to time while any of the CODES are outstanding, by dividend or otherwise, distribute to all or substantially all holders of shares of its Common Stock cash (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Price shall be reduced so that the same shall equal the rate determined by multiplying the Conversion Price in effect on the applicable record date by a fraction,

(1) the numerator of which shall be the Current Market Price on such record date less the full amount of cash so distributed as applicable to one share of Common Stock; and

(2) the denominator of which shall be the Current Market Price on such record date,

such adjustment to be effective immediately prior to the opening of business on the day following the Record Date; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such holder would have received had such Holder converted each Security on the Record Date. If such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

(f) In case a tender offer made by the Company or any of its Subsidiaries for all or any portion of the shares of Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of shares tendered) of an aggregate consideration having a Fair Market Value (as determined by the Board of Directors) that combined together with:

(1) the aggregate amount of the cash, plus the Fair Market Value (as determined by the Board of Directors), as of the expiration of such tender offer, of consideration payable in respect of any other tender offers, by the Company or any of its Subsidiaries for all or any portion of the shares of Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 12.3(f) has been made; and

(2) the aggregate amount of any distributions to all holders of shares of Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 12.3(e) has been made;

exceeds 10% of the product of the Current Market Price of the Common Stock as of the last time (the “Expiration Time”) tenders could have been made pursuant to such tender offer (as it may be amended), times the number of shares of Common Stock outstanding (including any tendered

shares) on the Expiration Time (such excess, the “Excess Amount”), then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the date of the Expiration Time by a fraction:

(1) the numerator of which shall be the (x) the product of (i) the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time and (ii) the Current Market Price of the Common Stock at the Expiration Time, less (y) the Excess Amount; and

(2) the denominator shall be the product of the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time and the Current Market Price of the Common Stock at the Expiration Time.

Such reduction (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all or a portion of such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such (or such portion of the) tender offer had not been made. If the application of this Section 12.3(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 12.3(f).

Pursuant to rights issued under the Company’s preferred share purchase rights plan, if holders of the CODES exercising the right of conversion attaching after the date the rights separate from the underlying Common Stock are not entitled to receive the rights that would otherwise be attributable to the shares of Common Stock received upon conversion, the Conversion Price will be adjusted as though the rights were being distributed to holders of Common Stock on the date of such separation. If such an adjustment is made and the rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment will be made to the conversion price on an equitable basis.

(g) For purposes of this Article 12, the following terms shall have the meanings indicated:

“Current Market Price” on any date means the average of the daily Sale Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to such date; provided, however, that if:

(1) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the Sale Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by dividing such Sale Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event;

(2) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e) or (f) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Sale Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event; and

(3) the “ex” date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Sale Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 12.3(d), (e) or (f)) of the evidences of Indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date.

For purposes of any computation under Section 12.3(f), if the “ex” date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Sale Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, when used:

(1) with respect to any issuance or distribution, means the first date on which the shares of Common Stock trade regular way on the relevant exchange or in the relevant market from which the Sale Price was obtained without the right to receive such issuance or distribution;

(2) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and

(3) with respect to any tender or exchange offer, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the Expiration Time of such offer.

Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 12.3, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

“Fair Market Value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction (as determined by the Board of Directors, whose determination shall be conclusive).

“Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of shares of Common Stock have the right to receive any cash, securities or other property or in which the shares of Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(h) The Company shall be entitled to make such additional reductions in the Conversion Price, in addition to those required by Sections 12.3(a), (b), (c), (d), (e) and (f), as shall be necessary in order that any dividend or distribution of Common Stock, any subdivision, reclassification or combination of shares of Common Stock or any issuance of rights or warrants referred to above shall not be taxable to the holders of Common Stock for United States federal income tax purposes.

(i) To the extent permitted by applicable law, the Company may, from time to time, reduce the Conversion Price by any amount for any period of time, if such period is at least 20 days and the reduction is irrevocable during the period. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the CODES maintained by the Registrar, at least 15 days prior to the date the reduced Conversion Price takes effect, a notice of the reduction stating the reduced Conversion Price and the period during which it will be in effect.

(j) In any case in which this Section 12.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date, the Company may elect to defer (but only for five Trading Days following the filing of the statement referred to in Section 12.5) issuing to the Holder of any CODES converted after such Record Date the shares of Common Stock issuable upon such conversion over and above the shares of Common Stock issuable upon such conversion on the basis of the Conversion Price prior to adjustment; provided, however, that the Company shall deliver to such Holder a due xxxx or other appropriate instrument evidencing such Holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment.

(k) All calculations under this Section 12.3 shall be made to the nearest cent or one-hundredth of a share, with one-half cent and 0.005 of a share, respectively, being rounded upward. Notwithstanding any other provision of this Section 12.3, the Company shall not be required to make any adjustment of the Conversion Price unless such adjustment would require an increase or decrease of at least 1% of such price; provided that the Company must carry forward any adjustments that are less than 1% of the Conversion Price and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1%, within one year of the first such adjustment carried forward. Any adjustments under this Section 12.3 shall be made successively whenever an event requiring such an adjustment occurs.

(l) In the event that at any time, as a result of an adjustment made pursuant to this Section 12.3, the Holder of any CODES thereafter surrendered for conversion shall become entitled to receive any shares of stock of the Company other than shares of Common Stock into which the CODES originally were convertible, the Conversion Price of such other shares so receivable upon conversion of any such CODES shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in subparagraphs (a) through (k) of this Section 12.3, and the provisions of Sections 12.1, 12.2 and 12.4 through 12.9 with respect to the Common Stock shall apply on like or similar terms to any such other shares and the determination of the Board of Directors as to any such adjustment shall be conclusive.

(m) No adjustment shall be made pursuant to this Section 12.3 (i) if the effect thereof would be to reduce the Conversion Price below the par value (if any) of the Common Stock or (ii) if the Holders of the CODES may participate in the transaction that would otherwise give rise to an adjustment pursuant to this Section 12.3.

Section 12.4. Consolidation or Merger of the Company.

If any of the following events occurs, namely:

(1) any reclassification or change of the outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination);

(2) any merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; or

(3) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock;

the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture, if such supplemental indenture is then required to so comply) providing that such CODES shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such CODES been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided, that if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or

conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“Non-Electing Share”), then for the purposes of this Section 12.4, the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 12. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the CODES as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article 12 hereof.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the CODES maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions of this Section 12.4 shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

If this Section 12.4 applies to any event or occurrence, Section 12.3 shall not apply.

The Company shall not enter into a transaction of the type described in this Section 12.4 unless the terms of this Section 12.4 are complied with in full.

Section 12.5. Notice of Adjustment.

Whenever an adjustment in the Conversion Price with respect to the CODES is required:

(1) the Company shall forthwith place on file with the Trustee and any Conversion Agent for such securities a certificate of the Treasurer of the Company, stating the adjusted Conversion Price determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of computing such adjustment; and

(2) a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be given by the Company or, at the Company’s written request, by the Trustee in the name and at the expense of the Company, to each Holder in the manner provided in Section 14.2. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

Section 12.6. Notice in Certain Events.

In case:

(1) of a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or conveyance to another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Exchange Act) of all or substantially all of the property and assets of the Company; or

(2) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or

(3) of any action triggering an adjustment of the Conversion Price referred to in clauses (x) or (y) below;

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the CODES in the manner provided in Section 14.2, at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of any distribution or grant of rights or warrants triggering an adjustment to the Conversion Price pursuant to this Article 12, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants are to be determined, or (y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the Conversion Price pursuant to this Article 12 is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger sale, conveyance, dissolution, liquidation or winding up.

Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in clause (1), (2) or (3) of this Section 12.6.

Section 12.7. Company to Reserve Stock; Registration; Listing.

(a) The Company shall, in accordance with the laws of the State of Wisconsin, at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock, for the purpose of effecting the conversion of the CODES, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all CODES then Outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of shares or securities, all such CODES would be held by a single Holder); provided, however, that nothing contained herein shall preclude the Company from satisfying its obligations in respect of the conversion of the CODES by delivery of purchased shares of Common Stock which are then held in the

treasury of the Company. The Company covenants that all shares of Common Stock that may be issued upon conversion of CODES will upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 12.8, taxes with respect to the issue thereof.

(b) If any shares of Common Stock which would be issuable upon conversion of CODES hereunder require registration with or approval of any governmental authority before such shares or securities may be issued upon such conversion, the Company will in good faith and as expeditiously as possible endeavor to cause such shares or securities to be duly registered or approved, as the case may be. The Company further covenants that so long as the Common Stock shall be listed on the New York Stock Exchange, the Company will, if permitted by the rules of such exchange, list and keep listed all Common Stock issuable upon conversion of the CODES, and the Company will endeavor to list the shares of Common Stock required to be delivered upon conversion of the CODES prior to such delivery upon any other national securities exchange upon which the outstanding Common Stock is listed at the time of such delivery.

Section 12.8. Taxes on Conversion.

The issue of stock certificates on conversion of CODES shall be made without charge to the converting Holder for any documentary, stamp or similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of CODES pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock or the portion, if any, of the CODES which are not so converted in a name other than that in which the CODES so converted were registered, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid.

Section 12.9. Conversion After Record Date.

Except as provided below, if any CODES are surrendered for conversion on any day other than an Interest Payment Date, the Holder of such CODES shall not be entitled to receive any Interest (including Contingent Interest) that has accrued on such CODES since the prior Interest Payment Date. By delivery to the Holder of the number of shares of Common Stock or other consideration issuable upon conversion in accordance with this Article 12, any accrued and unpaid Interest (including Contingent Interest) on such CODES will be deemed to have been paid in full.

If any CODES are surrendered for conversion subsequent to the Record Date preceding an Interest Payment Date but on or prior to such Interest Payment Date, the Holder of such CODES at the close of business on such Record Date shall receive the Interest (including Contingent Interest) payable on such CODES on such Interest Payment Date notwithstanding the conversion thereof. CODES surrendered for conversion during the period from the close of business on any Record Date preceding any Interest Payment Date to the opening of business on

such Interest Payment Date shall (except in the case of CODES which have been called for redemption on a Redemption Date within such period) be accompanied by payment by Holders, for the account of the Company, in New York Clearing House funds or other funds of an amount equal to the Interest (including Contingent Interest) payable on such Interest Payment Date on the CODES being surrendered for conversion. Except as provided in this Section 12.9, no adjustments in respect of payments of Interest (including Contingent Interest) on CODES surrendered for conversion or any dividends or distributions or interest on the Common Stock issued upon conversion shall be made upon the conversion of any CODES.

Section 12.10. Company Determination Final.

Any determination that the Company or the Board of Directors must make pursuant to this Article 12 shall be conclusive if made in good faith and in accordance with the provisions of this Article 12, absent manifest error, and set forth in a Board Resolution.

Section 12.11. Responsibility of Trustee for Conversion Provisions.

The Trustee has no duty to determine when an adjustment under this Article 12 should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of CODES. The Trustee shall not be responsible for any failure of the Company to comply with this Article 12. Each Conversion Agent other than the Company shall have the same protection under this Section 12.11 as the Trustee.

The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent acting hereunder.

Section 12.12. Unconditional Right of Holders to Convert.

Notwithstanding any other provision in this Indenture, the Holder of any CODES shall have the right, which is absolute and unconditional, to convert its CODES in accordance with this Article 12 and to bring an action for the enforcement of any such right to convert, and such rights shall not be impaired or affected without the consent of such Holder.

ARTICLE 13

SUBSIDIARY GUARANTEES

Section 13.1. Agreement to Guarantee.

The Guarantors, jointly and severally, hereby agree as follows:

(a) The Guarantors unconditionally guarantee to each Holder of a CODES authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, regardless of the validity and enforceability of the Indenture, the Securities or the Obligations of the Company under this Indenture or the Securities, that:

(1) the principal of, Interest (including Contingent Interest) on the CODES will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, Interest (including Contingent Interest) and Additional Amounts, if any, on the CODES, to the extent lawful, and all other Obligations of the Company to the Holders or the Trustee thereunder or under this Indenture will be promptly paid in full, all in accordance with the terms thereof; and

(2) in case of any extension of time for payment or renewal of any CODES or any of such other Obligations, that the same will be promptly paid in full when due in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

(b) Notwithstanding the foregoing, in the event that the Guarantees would constitute or result in a violation of any applicable fraudulent conveyance or similar law of any relevant jurisdiction, the liability of the Guarantors under this Indenture shall be reduced to the maximum amount permissible under such fraudulent conveyance or similar law.

Section 13.2. Execution and Delivery of Guarantees.

(a) To evidence the Guarantees set forth in this Indenture, the Guarantors hereby agree that a notation of such Guarantees shall be endorsed by an officer of each of the Guarantors on each CODES authenticated and delivered by the Trustee after the date hereof.

(b) Notwithstanding the foregoing, the Guarantors hereby agree that the Guarantees set forth herein shall remain in full force and effect notwithstanding any failure to endorse on each CODES a notation of such Guarantees.

(c) If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the CODES on which the Guarantees are endorsed, the Guarantees shall be valid nevertheless.

(d) The delivery of any CODES by the Trustee, after the authentication thereof under the Indenture, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantors.

(e) The Guarantors hereby, jointly and severally, agree that their obligations hereunder shall be unconditional, regardless of the validity, regularity or enforceability of the Securities or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the CODES with respect to any provisions of the Securities or the Indenture, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor.

(f) The Guarantors hereby waive diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that the Guarantees made pursuant to this Indenture will not be discharged except by complete performance of the obligations contained in the Securities and the Indenture.

(g) If any Holder or the Trustee is required by any court or otherwise to return to the Company or the Guarantors, or any Custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, the Guarantees made pursuant to this Indenture, to the extent theretofore discharged, shall be reinstated in full force and effect.

(h) The Guarantors agree that they shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. The Guarantors further agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand:

(1) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 4 of the Indenture for the purposes of the Guarantees made pursuant to this Indenture, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby; and

(2) in the event of any declaration of acceleration of such obligations as provided in Article 4 of the Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Guarantees made pursuant to this Indenture.

(3) The Guarantors shall have the right to seek contribution from any other non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders or the Trustee under the Guarantees made pursuant to this Indenture.

Section 13.3. Releases.

(a) Concurrently with any sale of assets (including, if applicable, all of the Capital Stock of the Guarantors), all Liens, if any, in favor of the Trustee in the assets sold thereby shall be released. If the assets sold in such sale or other disposition include all or substantially all of the assets of the Guarantors or all of the Capital Stock of the Guarantors, then the Guarantors (in the event of a sale or other disposition of all of the Capital Stock of any of the Guarantors) or the Person acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of any of the Guarantors) shall be released from and relieved of their obligations under this Indenture and their Guarantees made pursuant hereto. Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that such sale or other disposition was made by the Company or the Guarantors, as the case may be, in accordance with the provisions of this Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of the Guarantors from their obligations under this Indenture and the Guarantees made pursuant hereto. If the Guarantors are not released from their obligations under the Guarantees, they shall remain liable for the full amount of principal of and Interest (including Contingent Interest) on the CODES and for the other obligations of the Guarantors under this Indenture.

(b) Upon the designation of any of the Guarantors as an Excluded Subsidiary in accordance with the terms of the Indenture, such Guarantor shall be released and relieved of the obligations under this Indenture. Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such designation of such Guarantor as an Excluded Subsidiary was made by the Company in accordance with the provisions of this Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of such Guarantor from its obligations under its Guarantee. The Guarantors not released from their obligations under the Guarantees shall remain liable for the full amount of principal of and Interest (including Contingent Interest) on the CODES and for the other obligations of any of the Guarantors under this Indenture.

Section 13.4. No Recourse Against Others.

No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guarantors, as such, shall have any liability for any obligations of the Company or any Guarantor under the CODES, any Guarantees, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the CODES by accepting a CODES waives and releases all such liability. The waiver and release are part of the consideration for issuance of the CODES. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such officer knows, or in the exercise of reasonable care should know, that the Opinion of Counsel with respect to the matters upon which such certificate or opinion is based is erroneous. Any such Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

(1) a statement that each individual signing such certificate or opinion on behalf of the Company, has read such covenant or condition and the definitions herein relating thereto;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) a statement that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(4) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with.

Section 14.12. Counterparts.

This instrument may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original but all such counterparts shall together constitute but one and the same instrument.

Section 14.13. Legal Holidays.

In any case where any Interest Payment Date, Redemption Date, Repurchase Date or Stated Maturity of any CODES or the last day on which a Holder of a CODES has a right to convert such CODES shall not be a Business Day at any Place of Payment or Place of Conversion, then (notwithstanding any other provision of this Indenture or of the CODES) payment of interest, if any, or principal or conversion of the CODES, need not be made at such Place of Payment or Place of Conversion on such day, but may be made on the next succeeding Business Day at such Place of Payment or Place of Conversion with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repurchase Date or at the Stated Maturity or on such last day for conversion; provided, however, that in the case that payment is made on such succeeding Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repurchase Date or Stated Maturity, as applicable.

Section 14.14. Recourse Against Others.

No recourse for the payment of the principal or interest, if any, on any CODES, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, shareholder, officer or director or manager, as such, past, present or future, of the Company of any successor entity to either the Company, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance thereof and as part of the consideration for the issue thereof, expressly waived and released.

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed all as of the day and year first above written.

CUSIP No. 00000XXX0


Registered No.		Principal Amount: $

APOGENT TECHNOLOGIES INC., a corporation duly organized and existing under the laws of Wisconsin (herein called the “Company,” which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to CEDE & CO. or registered assigns, the principal sum of $ ( Dollars) [insert in global CODES: , as revised by the Schedule of Increases and Decreases in Global CODES attached hereto], on December 15, 2033, and to pay Interest (including Contingent Interest) thereon from and including December 17, 2003 or from and including the most recent Interest Payment Date to which Interest (including Contingent Interest) has been paid or duly provided for, as the case may be, at the rate calculated in accordance with the Indenture.

Interest (including any Contingent Interest) will be paid quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, beginning March 15, 2004, unless any such Interest Payment Date (other than an Interest Payment Date at maturity) would otherwise be a day that is not a Business Day, in which case the Interest Payment Date will be postponed to the next succeeding Business Day (except if that Business Day falls in the next succeeding calendar month, that Interest Payment Date will be the immediately preceding Business Day). The Interest (including Contingent Interest) so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this CODES (or one or more predecessor CODES) is registered in the Register at the close of business on the Regular Record Date for such Interest (including Contingent Interest), which shall be the March 1, June 1, September 1 and December 1 preceding the relevant Interest Payment Date. Except as otherwise provided in the Indenture, any such Interest (including Contingent Interest) not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this CODES (or one or more predecessor CODES) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof is to be given to Holders of CODES not less than 10 calendar days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the CODES may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

While this CODES is represented by one or more Global Securities registered in the name of the Depositary or its nominee, the Company will cause payments of principal and Interest (including Contingent Interest) on such Global Securities to be made to the Depositary or

its nominee, as the case may be, by wire transfer to the extent, in the funds and in the manner required by agreements with, or regulations or procedures prescribed from time to time by, the Depositary or its nominee, and otherwise in accordance with such agreements, regulations and procedures.

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS CODES SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, or its successor as Trustee, or its Authenticating Agent, by manual signature of an authorized signatory, this CODES will not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

[Reverse of CODES]

APOGENT TECHNOLOGIES INC.

Floating Rate Senior Convertible Contingent Debt Securities (CODES^SM) due 2033

SECTION 1. General. This CODES is one of a duly authorized issue of debt securities of the Company (herein called the “CODES”), issued under an Indenture, dated as of December 17, 2003 (the “Indenture”), among the Company, the Guarantors parties thereto and The Bank of New York, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the CODES and of the terms upon which the CODES are, and are to be, authenticated and delivered. The terms, conditions and provisions of the CODES are those stated in the Indenture, those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, and those set forth in this CODES. To the extent that the terms, conditions and other provisions of this CODES modify, supplement or are inconsistent with those of the Indenture, then the terms, conditions and other provisions of the Indenture shall govern. All terms used in this CODES that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

SECTION 2. Interest and Payments. This CODES will bear interest from December 17, 2003 or from and including the most recent Interest Payment Date to which Interest (including Contingent Interest) has been paid or duly provided for, as the case may be, at a per annum rate which will equal 3-month LIBOR, adjusted quarterly on each Interest Adjustment Date, as defined below, minus a spread of 125 basis points, which spread may be reset upon the occurrence of a Reset Transaction as described in the Indenture. Notwithstanding foregoing, Interest for the initial interest period commencing December 17, 2003 shall accrue at the rate of 0.0% (zero) per annum. In no event shall any quarterly adjustments of the interest rate or resetting of the spread result in the interest rate borne by the CODES being less than zero.

We will pay interest quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, beginning March 15, 2004, unless any such Interest Payment Date (other than an Interest Payment Date at maturity) would otherwise be a day that is not a business day, in which case the interest payment date will be postponed to the next succeeding business day (except if that business day falls in the next succeeding calendar month, that interest payment date will be the immediately preceding business day). If the maturity date of the CODES is a day that is not a business day, all payments to be made on such day will be made on the next succeeding business day, with the same force and effect as if made on the due date, and no additional interest will be payable as a result of such a delay in payment.

On each Interest Determination Date for the CODES, or as soon thereafter as practicable, the Calculation Agent shall determine the applicable Interest Rates as provided for and contemplated by the CODES. The Calculation Agent shall notify the Company and the Trustee of such Interest Rates as soon as reasonably practicable after the determination thereof. The Calculation Agent shall perform such other actions and undertake such other duties of the Calculation Agent as are described in the Indenture to be performed or undertaken by the Calculation Agent. The Calculation Agent shall not be responsible for calculating Contingent Interest.

A-4

The term “3-month LIBOR” as determined by the Calculation Agent means, with respect to any Interest Determination Date:

(1) the rate for 3-month deposits in United States dollars commencing on the related Interest Adjustment Date, that appears on the Moneyline Telerate Page 3750 (as described below) as of 11:00 A.M., London time, on the Interest Determination Date, unless fewer than two such offered rates so appear; or

(2) if fewer than two offered rates appear, or no rate appears, as the case may be, on the particular Interest Determination Date on the Moneyline Telerate Page 3750, the rate calculated by the Calculation Agent of at least two offered quotations obtained by the calculation agent after requesting the principal London offices of each of four major reference banks in the London interbank market to provide the Calculation Agent with its offered quotation for deposits in United States dollars for the period of three months, commencing on the related interest adjustment date, to prime banks in the London interbank markets at approximately 11:00 A.M., London time, on that Interest Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; or

(3) if fewer than two offered quotations referred to in clause (2) are provided as requested, the rate calculated by the Calculation Agent as the arithmetic mean of the rates quoted at approximately 11:00 A.M., New York time, on the particular interest determination date by three major banks (which will not include our affiliates) in the City of New York selected by the Calculation Agent for loans in United States dollars to leading European banks for a period of three months and in a principal amount that is representative for a single transaction in United States dollars in that markets at that time; or

(4) if the banks so selected by the Calculation Agent are not quoting as mentioned in clause (3), 3-month LIBOR in effect immediately prior to the particular Interest Determination Date.

The term “Interest Determination Date” means the second London banking day preceding the related Interest Adjustment Date.

The term “Interest Adjustment Date” means March 15, June 15, September 15 and December 15 of each year; provided that, if any Interest Adjustment Date would otherwise be a day that is not a Business Day, such Interest Adjustment Date shall be postponed to the next succeeding Business Day, except if such Business Day falls in the next succeeding calendar month, such Interest Adjustment Date will be the immediately preceding Business Day.

The term “London banking day” means a day on which commercial banks are open for business, including dealings in United States dollars, in London.

A-5

The term “Moneyline Telerate Page 3750” means the display on Moneyline Telerate (or any successor service) on such page (or any other page as may replace such page on such service) for the purpose of displaying the London interbank rates of major banks for United States dollars.

In addition, Contingent Interest will accrue on this CODES during any quarterly interest period, commencing with the quarterly interest period beginning December 15, 2009, under the conditions specified in the Indenture at an amount equal to 0.0625% of the average trading price of the CODES over the measuring period triggering the contingent interest payment.

Interest on this CODES, including Contingent Interest, will be payable on the Interest Payment Date or Interest Payment Dates as specified on the face hereof and, in either case, at Maturity. Except as provided below, Interest (including Contingent Interest) will be paid (i) if this CODES is represented by one or more Global Securities, to DTC in immediately available funds, (ii) if this CODES is represented by one or more certificated CODES by check mailed to the Holders of such CODES unless, in the case of Holders of certificated CODES having a principal amount of more than $5,000,000, such Holders shall have made written application to the Registrar not later than the relevant Regular Record Date requesting payment by wire transfer, in which case payment shall be made by wire transfer in immediately available funds. Principal will be paid (i) if this CODES is represented by one or more Book-Entry Notes, to DTC in immediately available funds or (ii) if this CODES is represented by one or more certificated CODES, at our office or agency in New York City, which initially will be the office or agency of the trustee in New York City.

Payments on this CODES with respect to any Interest Payment Date or Maturity will include Interest (including Contingent Interest) accrued from and including the original date of issuance, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, to but excluding such Interest Payment Date or Maturity, except as may otherwise be provided in the Indenture. Interest (including Contingent Interest) on the CODES shall be computed on the basis of the actual number of days for which Interest is payable in the relevant interest period, divided by 360.

Except as provided below, if any CODES is surrendered for conversion on any day other than an Interest Payment Date, the Holder of such CODES shall not be entitled to receive any Interest (including Contingent Interest) that has accrued on such CODES since the prior Interest Payment Date. By delivery to the Holder of the number of shares of Common Stock or other consideration issuable upon conversion in accordance with Indenture, any accrued and unpaid Interest (including Contingent Interest) on such CODES shall be deemed to have been paid in full.

If any CODES is surrendered for conversion subsequent to the Regular Record Date preceding an Interest Payment Date but on or prior to such Interest Payment Date (except CODES called for redemption on a Redemption Date between such Regular Record Date and Interest Payment Date), the Holder of such CODES at the close of business on such Regular Record Date shall be entitled to receive the Interest (including Contingent Interest) payable on such CODES on such Interest Payment Date notwithstanding the conversion thereof. Any CODES surrendered for conversion during the period from the close of business on any Regular

A-6

Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of CODES which have been called for redemption on a Redemption Date within such period) be accompanied by payment in New York Clearing House funds or other funds of an amount equal to the Interest (including Contingent Interest) payable on such Interest Payment Date on the CODES being surrendered for conversion. Except as provided in this Section 2 or in Indenture, no adjustments in respect of payments of Interest (including Contingent Interest) on any CODES surrendered for conversion or any dividends or distributions or Interest (including Contingent Interest) on the Common Stock issued upon conversion shall be made upon the conversion of any CODES.

All percentages resulting from any calculation with respect Interest (including Contingent Interest) will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (with five one-millionths of a percentage point being rounded upward) and all dollar amounts used in or resulting from any such calculation with respect to this CODES will be rounded to the nearest cent (with one-half cent being rounded upward).

If an Interest Payment Date or Maturity for this CODES falls on a day that is not a Business Day, payment of principal and Interest (including Contingent Interest) to be made on such day with respect to this CODES will be made on the next succeeding day that is a Business Day (except if that Business Day falls in the next succeeding calendar month, that Interest Payment Date will be the immediately preceding Business Day) and if the date of Maturity is a day that is not a Business Day, all payments to be made on such day will be made on the next succeeding Business Day, with the same force and effect as if made on the due date, and no additional interest will be payable as a result of such a delay in payment.

SECTION 3. Redemption. This CODES is subject to redemption at the option of the Company, at any time on or after March 15, 2010, in whole or from time to time in part in increments of $1,000 or an integral multiple of $1,000 (provided that any remaining principal amount hereof shall be an authorized denomination), at a Redemption Price equal to 100% of the principal amount, plus accrued and unpaid Interest, including Contingent Interest, to, but excluding, the Redemption Date. However, payments due with respect to this CODES on or prior to the Redemption Date will be payable to the Holder of this CODES of record at the close of business on the relevant Regular Record Date specified on the face hereof, all as provided in the Indenture. The Company may exercise such option by causing the Trustee to mail a notice of such redemption, at least 20 but not more than 60 calendar days prior to the date of redemption, in accordance with the provisions of the Indenture. In the event of redemption of this CODES in part only, this CODES will be cancelled and new CODES representing the unredeemed portion hereof will be issued in the name of the Holder hereof.

SECTION 4. Conversion. Subject to and in compliance with the provisions of the Indenture, a Holder is entitled, at such Holder’s option, to convert the Holder’s CODES (or any portion of the principal amount thereof that is $1,000 or an integral multiple $1,000), into fully paid and nonassessable shares of Common Stock at the Conversion Price in effect at the time of conversion, under certain circumstances set forth in the Indenture.

A-7

A CODES in respect of which a Holder has delivered a Repurchase Notice exercising the option of such Holder to require the Company to repurchase such CODES may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Price is $33.09 per share of Common Stock (a Conversion Rate of approximately 30.22 shares of Common Stock per $1,000 principal amount of CODES ), subject to adjustment in certain events described in the Indenture. A Holder that surrenders CODES for conversion will receive cash or a check in lieu of any fractional share of Common Stock. The Company from time to time may voluntarily reduce the Conversion Price.

To surrender a CODES for conversion, a Holder must (1) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the CODES to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents and (4) pay any transfer or similar tax, if required.

No fractional shares of Common Stock shall be issued upon conversion of any CODES. Instead of any fractional share of Common Stock that would otherwise be issued upon conversion of such CODES, the Company shall pay a cash adjustment as provided in the Indenture.

No payment or adjustment will be made for dividends on the shares of Common Stock, except as provided in the Indenture.

If the Company (i) is a party to a consolidation, merger or binding share exchange (ii) reclassifies the Common Stock or (iii) conveys, transfers or leases its properties and assets substantially as an entirety to any Person, the right to convert a CODES into shares of Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or such other Person.

SECTION 5. Repurchase By the Company at the Option of the Holder. Subject to the terms and conditions of the Indenture and at the option of the Holder, on December 15, 2008, March 15, 2010, December 15, 2014, December 15, 2019, December 15, 2024 and December 15, 2029, the Company shall become obligated to purchase all of such Holder’s CODES, or any portion of the principal amount thereof that is equal to any integral multiple of $1,000, at a repurchase price equal to 100% of the principal amount of the CODES to be repurchased, plus accrued and unpaid Interest (including Contingent Interest) to, but excluding, the Repurchase Date. In addition, subject to the terms and conditions of the Indenture and at the option of the Holder, following the occurrence of a Change of Control, the Company shall become obligated to purchase all of such Holder’s CODES, or any portion of the principal amount thereof that is equal to any integral multiple of $1,000, on the date that is 30 days after the date of the Company Notice given in connection with such Change of Control at a repurchase price equal to 100% of the principal amount of the CODES to be repurchased, plus accrued and unpaid Interest (including Contingent Interest) to, but excluding, the Change of Control Repurchase Date.
