(a) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto;

(b) 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;

Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as an “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee reasonably deems sufficient.

(c) The Company may, in the circumstances permitted by the Trust Indenture Act, fix any day as the record date for the purpose of determining the Holders entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted to be given or taken by Holders.

With regard to any record date, only the Holders on such date (or their duly designated proxies) shall be entitled to give or take, or vote on, the relevant action.

(d) The ownership of Securities shall be proved by the Security Register.

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

SECTION 1.05. Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

(i) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office; or

(ii) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company, Attention: Secretary.

The Trustee agrees to accept and act upon facsimile transmission of written instructions and directions pursuant to this Indenture given by the Company; provided, however, that: (i) the Company, subsequent to such facsimile transmission of written instructions and/or directions, shall provide the originally executed instructions and/or directions to the Trustee in a timely manner and (ii) such originally executed instructions and/or directions shall be signed by an Authorized “Officer” of the Company.

SECTION 1.06. Notice to Holders; Waiver. Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at such Holder’s address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Whenever under this Indenture the Trustee is required to provide any notice by mail, in all cases the Trustee may alternatively provide notice by overnight courier or by telefacsimile, with confirmation of transmission.

SECTION 1.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required hereunder to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 1.08. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof, and all Article and Section references are to Articles and Sections, respectively, of this Indenture unless otherwise expressly stated.

SECTION 1.09. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

SECTION 1.10. Severability Clause. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 1.11. Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their respective successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 1.12. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York.

SECTION 1.13. Legal Holiday. In any case where any Interest Payment Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or at the Stated Maturity and no interest shall accrue with respect to such payment for the period from and after such Interest Payment Date or Stated Maturity, as the case may be.

SECTION 1.14. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

SECTION 1.15. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

		Authorized Signatory

SECTION 2.03. Form of Reverse of Security. This Security is one of a duly authorized issue of Securities of the Company, designated as its 3.50% Senior Convertible Notes Due 2038 (the “Securities”), all issued or to be issued under and pursuant to an Indenture, dated as of November 16, 2007 (the “Indenture”), between the Company and The Bank of New York Trust Company, N.A. (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities.

The indebtedness evidenced by the Securities is unsecured and unsubordinated senior indebtedness of the Company and ranks equally with the Company’s other unsecured and unsubordinated senior indebtedness.

The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the date on which the Indenture was qualified under the TIA. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern.

Redemption at the Option of the Company. No sinking fund is provided for the Securities. The Securities are redeemable as a whole, or from time to time in part, at any time on or after January 15, 2013 at the option of the Company at a redemption price equal to 100% of the Principal Amount of Securities to be redeemed, together with accrued and unpaid interest to, but excluding, the Redemption Date (the “Redemption Price”) (unless the Redemption Date is after a Record Date and on or prior to the Interest Payment Date to which it relates, in which case such accrued and unpaid interest on such Interest Payment Date shall be paid to the Holder of record on such Record Date, and the Redemption Price shall be equal to 100% of the Principal Amount of Securities to be redeemed). The Redemption Price will be paid in cash.

Repurchase by the Company at the Option of the Holder. Subject to the terms and conditions of the Indenture, the Company shall become obligated to repurchase, at the option of the Holder, the Securities held by such Holder on January 15, 2013, January 15, 2018 and January 15, 2028 (each a “Repurchase Date”) at a price equal to 100% of the Principal Amount of Securities to be repurchased (and accrued and unpaid interest to, but excluding, the Repurchase Date shall be paid on the Repurchase Date to the Holder of record on the immediately preceding Record Date) (the “Repurchase Price”), upon delivery of a Repurchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 30 Business Days prior to such Repurchase Date until the close of business on the Business Day prior to such Repurchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture. The Repurchase Price will be paid in cash.

Repurchase by the Company at the Option of the Holder Upon a Fundamental Change. Subject to the terms and conditions of the Indenture, the Company shall become obligated, at the option of the Holder, to repurchase the Securities if a Fundamental Change occurs at any time prior to the Stated Maturity at 100% of the Principal Amount plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”) (unless the Fundamental Change Repurchase Date is after a Record Date and on or prior to the Interest Payment Date to which it relates, in which case such accrued and unpaid interest on such Interest Payment Date shall be paid to the Holder of record on such Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the Principal Amount of Securities to be repurchased). The Fundamental Change Repurchase Price will be paid in cash.

Withdrawal of Repurchase Notice and Fundamental Change Repurchase Notice. Holders have the right to withdraw, in whole or in part, any Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

Payment of Redemption Price, Repurchase Price and Fundamental Change Repurchase Price. If cash sufficient to pay the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price, as the case may be, of all Securities or portions thereof to be redeemed or repurchased on a Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, as the case may be, the Securities to be redeemed or repurchased will cease to be outstanding and interest will cease to accrue on such Securities (or portions thereof) immediately after such Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, as the case may be, and the Holder thereof shall have no other rights as such (other than the right to receive the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price, as the case may be) upon surrender of such Security.

Conversion. Subject to the terms and conditions of the Indenture, a Holder may convert each of its Securities into shares of Common Stock, at such Holder’s option at any time and from time to time, at an initial conversion rate of 33.1991 shares per $1,000 Principal Amount of Securities (the “Conversion Rate”), prior to the close of business on January 14, 2038. The Conversion Rate in effect at any given time is subject to adjustment, and shall be increased by a number of additional shares of Common Stock specified in the Indenture in the event such conversion occurs in connection with certain specified Fundamental Change transactions occurring on or prior to January 15, 2013. A Holder may convert fewer than all of such Holder’s Securities so long as the Securities converted are an integral multiple of $1,000 Principal Amount. Holders will not receive any cash payment representing accrued and unpaid interest upon conversion of a Security. Accrued and unpaid interest will be deemed paid in full rather than canceled, extinguished or forfeited; provided, that if this Security shall be surrendered for conversion during the period from close of business on any Record Date for the payment of interest through the close of business on the Business Day next preceding the following Interest Payment Date, (1) accrued and unpaid interest on such Interest

Payment Date shall be paid to the Holder of record on such Record Date, notwithstanding such conversion, and (2) upon conversion such Security (or portion thereof being converted) must be accompanied by an amount, in funds acceptable to the Company, equal to the interest payable on such Interest Payment Date on the Principal Amount being converted, except that no such payment described in this clause (2) shall be required (A) in respect of conversions following the Record Date immediately preceding January 15, 2038, (B) if the Company shall have specified a Redemption Date or Fundamental Change Repurchase Date that is after a Record Date and on or prior to the immediately following Interest Payment Date or (C) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

[INCLUDE IF SECURITY IS A GLOBAL SECURITY. In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depositary.]

If an Event of Default shall occur and be continuing, the Principal Amount plus accrued and unpaid interest through such date on all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate Principal Amount of the Outstanding Securities. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate Principal Amount of the Outstanding Securities, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of any provision of or applicable to this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities, the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity satisfactory to it, the Trustee shall not have received from the Holders of a majority in Principal Amount of Outstanding Securities a direction inconsistent with such request, and the Trustee shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the

Holder of this Security for the enforcement of any payment of said principal hereof or interest hereon on or after the respective due dates expressed herein or for the enforcement of any conversion right.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Principal Amount, Repurchase Price or Fundamental Change Repurchase Price of or interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in The City of New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate Principal Amount, will be issued to the designated transferee or transferees.

The Securities are issuable only in registered form in denominations of $2,000 and any integral multiple of $1,000 above that amount, as provided in the Indenture and subject to certain limitations therein set forth. Securities are exchangeable for a like aggregate Principal Amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this 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 this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The Securities

SECTION 3.01. Title and Terms. The aggregate Principal Amount of Securities that may be authenticated and delivered under this Indenture on the original Issue Date is limited to $275,000,000 (subject to increase by up to $41,250,000 in the event the Underwriter exercises the over-allotment option granted to it in the Underwriting Agreement), except for Securities authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of, other Securities pursuant to Section 3.04, 3.05, 3.06, 9.06, 11.06 or 11.12.

Following the original Issue Date, the Company shall be entitled to, without notice to or the consent of the Holders of Securities, issue, in an unlimited aggregate principal amount, additional Securities under this Indenture having the same terms as and ranking equally and ratably with the Securities issued on the original Issue Date in all respects, so that such additional Securities shall form a single series with, and shall have the same terms as to status, redemption or otherwise as, the Securities issued on the original Issue Date. Such additional Securities may have CUSIP numbers that are the same as or different from the Securities issued on the original Issue Date.

The Securities shall be known and designated as the “3.50% Senior Convertible Notes Due 2038” of the Company. The Principal Amount shall be payable at the Stated Maturity.

The Principal Amount and accrued interest on the Securities shall be payable at the office or agency of the Company in The City of New York maintained for such purpose and at any other office or agency maintained by the Company for such purpose; provided, however, that at the option of the Company payments may be made by wire transfer or by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

The Securities shall not have the benefit of a sinking fund.

The Securities shall not be superior in right of payment to, and shall rank pari passu with, all other unsecured and unsubordinated indebtedness of the Company.

SECTION 3.02. Denominations. The Securities shall be issuable only in registered form without coupons and in denominations of $2,000 and any integral multiple of $1,000 above that amount.

SECTION 3.03. Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its Chief Financial Officer, its President or one of its Vice Presidents.

Securities bearing the manual or facsimile signatures of individuals who were at any time 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 such Securities.

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. The Company Order shall specify the amount of Securities to be authenticated, and shall further specify the amount of such Securities to be issued as a Global Security or as Physical Securities. The Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

Each Security shall be dated the date of its authentication.

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 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.

SECTION 3.04. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 10.02, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like Principal Amount of definitive Securities of authorized denominations. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

SECTION 3.05. Registration; Registration of Transfer and Exchange; Restrictions on Transfer. (a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 10.02 being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable

regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” (the “Security Registrar”) for the purpose of registering Securities and transfers of Securities as herein provided.

Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 10.02 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, each such Security bearing such restrictive legends as may be required by this Indenture (including Section 2.02).

At the option of the Holder and subject to the other provisions of this Section 3.05 and to Section 3.09, Securities may be exchanged for other Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04 not involving any transfer.

The Company shall not be required to exchange or register a transfer of any Security (i) during the 15-day period immediately preceding the mailing of any notice of redemption of any Security, (ii) after any notice of redemption has been given to Holders, except, where such notice provides that such Security is to be redeemed only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be redeemed, (iii) that has been surrendered for conversion or (iv) as to which a Repurchase Notice or Fundamental Change Repurchase Notice has been delivered and not withdrawn, except, where such Repurchase Notice or Fundamental Change Repurchase Notice provides that such Security is to be purchased only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be purchased.

(b) Neither the Trustee nor any of its agents shall (i) have any duty to monitor compliance with or with respect to any federal or state or other securities or tax laws or (ii) have any duty to obtain documentation relating to any transfers or exchanges other than as specifically required hereunder.

SECTION 3.06. Mutilated, Destroyed, Lost and 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 Principal Amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) 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 notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and 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 or has been called for redemption in full, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section 3.06, the Company may require payment by the Holder 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 3.06 in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and 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 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 3.07. 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 the principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security shall 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 3.08. Book-Entry Provisions for Global Securities. (a) The Global Securities initially shall (i) be registered in the name of the Depositary or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for the Depositary and (iii) bear legends as set forth on the face of the form of Security in Section 2.02.

Members of, or participants in, the Depositary (“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 the 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 the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of any Holder.

(b) Transfers of the Global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred or exchanged, in whole or in part, for Physical Securities in accordance with the rules and procedures of the Depositary and the provisions of Section 3.09. In addition, Physical Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Securities if (A) such Depositary has notified the Company (or the Company becomes aware) that the Depositary (i) is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act when the Depositary is required to be so registered to act as such Depositary and, in either such case, no successor Depositary shall have been appointed within 90 days of such notification or of the Company becoming aware of such event; (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Outstanding Securities shall have become due and payable pursuant to Section 5.02 and the Trustee requests that Physical Securities be issued; or (C) the Company, at its option, notifies the Trustee that it elects to cause the issuance of Physical Securities, subject to applicable procedures of the Depositary.

(c) In connection with any transfer or exchange of a portion of the beneficial interest in the Global Security to beneficial owners pursuant to clause (b) of this Section 3.08, the Security Registrar shall (if one or more Physical Securities are to be issued) reflect on its books and records the date and a decrease in the Principal Amount of the Global Security in an amount equal to the Principal Amount of the beneficial interest in the Global Security 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.

(d) In connection with the transfer of the entire Global Security to beneficial owners pursuant to clause (b) of this Section 3.08, the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate Principal Amount of Physical Securities of authorized denominations and the same tenor.

(e) The Holder of the Global Securities 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.

SECTION 3.09. Cancellation and Transfer Provisions. The Company at any time may deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold. The Trustee shall cancel and dispose of all Securities surrendered for registration of transfer, exchange, payment, purchase, repurchase, redemption, conversion (pursuant to Article 13 hereof) or cancellation in accordance with its customary practices. 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 and until the same are delivered to the Trustee for cancellation. The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for cancellation.

The Security Registrar shall retain, in accordance with its customary procedures, copies of all letters, notices and other written communications received pursuant to this Section 3.09. 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 Security Registrar.

SECTION 3.10. CUSIP Numbers. In issuing the Securities, the Company may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption 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 will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE IV

Satisfaction and Discharge

SECTION 4.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

(a) either

(i) all Securities theretofore authenticated and delivered (other than (A) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.06 and (B) Securities for whose payment money has theretofore been deposited with the Trustee in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust as provided in Section 10.03) have been delivered to the Trustee for cancellation; or

(ii) all such Securities not theretofore delivered to the Trustee for cancellation have become due and payable and the Company has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire indebtedness evidenced by such Securities not theretofore delivered to the Trustee for cancellation;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.07 and, if money shall have been deposited with the Trustee pursuant to clause (a)(ii) of Section 4.01, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.03 shall survive such satisfaction and discharge.

SECTION 4.02. Application of Trust Money. Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and interest for whose payment such money has been deposited with the Trustee.

ARTICLE V

Remedies

SECTION 5.01. Events of Default. “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) default in the payment of interest on any Securities when due and payable and such default continues for a period of 30 days; or

(b) default in the payment of the Principal Amount, Redemption Price, Repurchase Price or Fundamental Change Repurchase Price on any Security when it becomes due and payable; or

(c) default in the performance of any covenant, agreement or condition of the Company in this Indenture or the Securities (other than a default specified in clause (a) or (b) above), and such default continues for a period of 90 days after there has been given, by registered or certified mail, 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 Securities a written notice specifying such default and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(d) default in the Company’s obligation to convert the Securities into shares of its Common Stock upon exercise of a Holder’s conversion rights in accordance with Article 13 hereof and such default continues for a period of 10 days; or

(e) default by the Company or any Subsidiary in the payment of the principal or interest on any loan agreement or other instrument under which there may be outstanding, or by which there may be evidenced, any debt for money borrowed in excess of $50.0 million in the aggregate of the Company and its Subsidiaries (other than indebtedness for borrowed money secured only by the real property to which the indebtedness relates and which is non-recourse to the Company or to such Subsidiary), whether such debt now exists or shall hereafter be created, resulting in such debt becoming or being declared due and payable prior to its stated maturity, and such acceleration shall not have been rescinded or annulled within 60 days after written notice has been received by the Company or such Subsidiary from the Trustee or by the Trustee, the Company and such Subsidiary by the Holders of at least 25% in Principal Amount of Outstanding Securities; provided that if any time before a judgment or decree has been obtained by the Trustee as hereinafter provided, such default is remedied or cured by the Company within the applicable cure period, or is waived or rescinded by the holders of such indebtedness or is otherwise annulled, default under this clause (e) shall be deemed to have been remedied, cured, waived, rescinded or annulled, as the case may be; or

(f) failure by the Company to give the Fundamental Change Company Notice; or

(g) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company of a voluntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company as 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 federal or state law or (iii) 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; or

(h) the commencement by the Company of a voluntary case or proceeding under any applicable 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 it to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable federal or state law, or the consent by it to the filing of such petition or to the appointment of or 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 it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action.

SECTION 5.02. Acceleration of Maturity; Rescission and Annulment. (a) If an Event of Default (other than those specified in clauses (g) and (h) of Section 5.01) occurs and is continuing, then and in every such case (subject to Section 5.02(c)) the Trustee or the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities may declare the Principal Amount plus accrued and unpaid interest on all the Outstanding Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such Principal Amount plus accrued and unpaid interest shall become immediately due and payable.

Notwithstanding the foregoing, in the case of an Event of Default specified in clauses (g) and (h) of Section 5.01, the Principal Amount plus accrued and unpaid interest on all Outstanding Securities will ipso facto become due and payable without any declaration or other Act on the part of the Trustee or any Holder.

(b) At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article 5 provided, the Holders of a majority in aggregate Principal Amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if such rescission and annulment will not conflict with any judgment or decree of a court of competent jurisdiction and

(i) the Company has paid or deposited with the Trustee a sum sufficient to pay

(A) all overdue interest on the Securities,

(B) the Principal Amount plus accrued and unpaid interest, Redemption Price, Repurchase Price or Fundamental Change Repurchase Price, as applicable, on any Securities which have become due otherwise than by such declaration of acceleration, and

(C) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 6.07; and

(ii) all Events of Default, other than the non-payment of the Principal Amount plus accrued and unpaid interest on Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.12.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

(c) Notwithstanding anything to the contrary in this Section 5.02, to the extent the Company shall elect by written notice to the Trustee and the Paying Agent on or prior to the close of business on the date of occurrence of an Event of Default under Section 5.01(c) arising from the failure to comply with Section 10.06, the sole remedy for such an Event of Default shall for the first 90 days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest on the Securities at an annual rate of 0.25% of the Principal Amount of the Securities. If the Company so elects, such additional interest shall accrue on all outstanding Securities from and including the date on which such an Event of Default first occurs to but not including the 91st day thereafter (or such earlier date on which such Event of Default shall have been cured or waived in accordance herewith). On such 91st day (or earlier, if such Event of Default is cured or waived prior to such 91st day), such additional interest shall cease to accrue and, if such Event of Default has not been cured or waived in

accordance herewith prior to such 91st day, the Securities shall be subject to acceleration as provided in Section 5.02(a). For the avoidance of doubt, such additional interest shall not begin accruing until the Company shall have failed to comply with
Section 10.06(a) for a period of 90 days after the Notice of Default in respect thereof shall have been given to the Company as provided in Section 5.01(c). In the event that the Company shall not have elected to pay the additional interest in accordance with this Section 5.02(c) or, if elected, shall fail to pay such additional interest in accordance with this Section 5.02(c), the Securities shall be subject to acceleration as provided in Section 5.02(a).

SECTION 5.03. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if a default is made in the payment of the Principal Amount plus accrued and unpaid interest at the Maturity thereof or in the payment of the Redemption Price, the Repurchase Price or the Fundamental Change Repurchase Price in respect of any Security, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities, 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 an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the Principal Amount plus accrued but unpaid interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 5.04. Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder 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, to pay to the Trustee any amount due 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 6.07.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 5.05. Application of Money Collected. 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 and, in case of the distribution of such money to Holders, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 6.07;

SECOND: To the payment of the amounts then due and unpaid on the Securities for the Principal Amount, Redemption Price, Repurchase Price, Fundamental Change Repurchase Price or interest, as the case may be, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities; and

THIRD: To the Company.

SECTION 5.06. Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder (other than in the case of an Event of Default specified in clause (a) or (b) of Section 5.01), unless:

(i) such Holder has previously given written notice to the Trustee of a continuing Event of Default;

(ii) the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request;

(iv) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity has failed to institute any such proceeding; and

(v) no direction, in the opinion of the Trustee, inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate Principal Amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing itself of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

SECTION 5.07. Unconditional Right of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the Principal Amount, Redemption Price, Repurchase Price, Fundamental Change Repurchase Price or interest in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or any Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, as applicable, and to convert the Securities in accordance with Article 13, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder.

SECTION 5.08. Restoration of Rights and Remedies. If the Trustee or any Holder 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 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 5.09. 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 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders 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 now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 5.10. 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 an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 5.11. Control by Holders. The Holders of a majority in Principal Amount of the Outstanding Securities 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; provided that:

(i) such direction shall not be in conflict with any rule of law or with this Indenture; and

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

SECTION 5.12. Waiver of Past Defaults. The Holders of not less than a majority in Principal Amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past Default hereunder and its consequences, except a Default:

(i) Described in clause (a) or (b) of Section 5.01; or

(ii) in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

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; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

SECTION 5.13. Undertaking for Costs. 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 or omitted by it as Trustee, in either case in respect of the Securities, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney’s fees and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section 5.13 shall not apply to any suit instituted by the Company, 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% in Principal Amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the Principal Amount or interest on any Security on or after Maturity of such Security, or the Redemption Price, the Repurchase Price or the Fundamental Change Repurchase Price, as applicable, when due.

SECTION 5.14. 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 or 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 VI

The Trustee

SECTION 6.01. Certain Duties and Responsibilities. The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Except during the continuance of an Event of Default, the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee. In case an Event of Default with respect to the Securities has occurred (which has not been cured or waived), the Trustee shall exercise 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.

(d) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(f) 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, 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;

(k) 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;

(l) The permissive rights of the Trustee to take certain actions under this Indenture shall not be construed as a duty unless so specified herein; and

(m) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

SECTION 6.04. Not Responsible for Recitals. The recitals contained herein and in the Securities, except the Trustee’s certificates 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 6.05. May Hold Securities. The Trustee, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Section 6.08 and 6.13, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar or such other agent.

SECTION 6.06. Money Held in Trust. Money held by the Trustee in trust hereunder need 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 agreed in writing with the Company.

SECTION 6.07. Compensation and Reimbursement. The Company agrees:

(i) to pay to the Trustee from time to time such compensation for all services rendered by it hereunder as the Company and the Trustee shall from time to time agree in writing (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(ii) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture

(including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be caused by its negligence or willful misconduct; and

(iii) to indemnify the Trustee and any predecessor Trustee for, and to hold it harmless against, any loss, liability, claim, damage or expense including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending itself against any claim (whether assessed by the Company, by any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

The obligations of the Company under this Section 6.07 shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. To secure the Company’s payment obligations in this Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on the Securities. Such lien shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after a Default or an Event of Default specified in clauses (g) or (h) of Section 5.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under U.S. Code, Title 11 or any other similar foreign, federal or state law for the relief of debtors.

SECTION 6.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

SECTION 6.09. Corporate Trustee Required; Eligibility. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has, or whose parent banking company has, a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section 6.09, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 6.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

SECTION 6.10. Resignation and Removal; Appointment of Successor.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article 6 shall become effective until the acceptance of appointment by the successor Trustee under Section 6.11.

(b) The Trustee may resign at any time by giving written notice thereof to the Company. 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, the resigning Trustee may petition any court of competent jurisdiction at the expense of the Trustee for the appointment of a successor Trustee.

(c) The Trustee may be removed at any time by Act of the Holders of majority in Principal Amount of the Outstanding Securities, delivered to the Trustee and to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities.

(d) If at any time:

(i) the Trustee shall fail to comply with Section 6.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(ii) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or

(iv) a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Company Order may remove the Trustee, or (B) subject to Section 5.13, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of such Holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Company Order, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in Principal Amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the manner provided in Section 1.06. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

SECTION 6.11. Acceptance of Appointment by Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article 6.

SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee by sale or otherwise, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article 6, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 6.13. Preferential Collection of Claims Against. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

Covenants

SECTION 10.01. Payments. The Company shall duly and punctually make all payments in respect of the Securities in accordance with the terms of the Securities and this Indenture.

Any payments made or due pursuant to this Indenture shall be considered paid on the applicable date due if by 10:00 a.m., New York City time, on such date the Paying Agent holds, in accordance with this Indenture, cash sufficient to pay all such amounts then due. Payment of the principal and interest on the Securities shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

The Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served, which shall initially be the Corporate Trust Office of the Trustee. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies (in or outside the Borough of Manhattan, The City of New York) where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 10.03. Money for Security Payments to be Held in Trust. If the Company shall at any time act as its own Paying Agent, it shall, on or before each due date of any payment in respect of any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to make the payment so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents, it will, prior to each due date of any payment in respect of any Securities, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company shall cause each Paying Agent other than the Trustee 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 10.03, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying

Agent and (ii) during the continuance of any Default by the Company (or any other obligor upon the Securities) in the making of any payment in respect of the Securities, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as such.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the making of payments in respect of any Security and remaining unclaimed for two years after such payment has become due shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York or San Francisco, California, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Company. In the absence of a written request from the Company to return funds remaining unclaimed for two years after such payment has become due to the Company, the Trustee shall from time to time deliver all unclaimed payments to or as directed by applicable escheat authorities, as determined by the Trustee in its sole discretion, in accordance with the customary practices and procedures of the Trustee. Any such unclaimed funds held by the Trustee pursuant to this Section 10.03 shall be held uninvested and without any liability for interest.

SECTION 10.04. Statement by Officers as to Default. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof the Company is in Default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge.

The Company shall deliver to the Trustee, as soon as possible and in any event within 30 days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an

Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default and the action which the Company is taking or proposes to take with respect thereto.

SECTION 10.05. Existence. Subject to Article 8, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 10.06. Reports and Delivery of Certain Information. (a) The Company shall comply with Section 314(a) of the Trust Indenture Act as it relates to reports, information and documents that the Company may be required to file with the Trustee pursuant to such Section 314(a) and with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or otherwise by the Exchange Act, the Trust Indenture Act or other rules and regulations of the Commission, and shall file such reports, information and documents with the Trustee within 30 calendar days after the same are filed with the Commission; provided that in each case the delivery of materials to the Trustee by electronic means or filing of documents pursuant to the Commission’s “XXXXX” system (or any successor electronic filing system) shall be deemed to constitute “filing” with the Trustee for purposes of this
Section 10.06. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

(b) The Company shall file with the Trustee and the Commission and transmit to Holders such other information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant to such Act.

SECTION 10.07. [Reserved]

SECTION 10.09. Information for IRS Filings. The Company shall provide to the Trustee on a timely basis such information as the Trustee requires to enable the Trustee to prepare and file any form required to be submitted by the Company with the Internal Revenue Service and the Holders of the Securities.

Redemption and Repurchases

SECTION 11.01. Right to Redeem; Notices to Trustee. Prior to January 15, 2013, the Securities are not redeemable. At any time on or after January 15, 2013, the Securities are redeemable as a whole, or from time to time in part, at the option of the Company at the Redemption Price.

The Company shall give notice to the Trustee of its election to redeem Securities by a Company Order, at least 30 days but not more than 60 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).

SECTION 11.02. Selection of Securities to be Redeemed. If less than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata or by lot or by any other method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange on which the Securities are then listed). The Trustee shall make the selection within seven days from its receipt of the notice from the Company delivered pursuant to the second paragraph of Section 11.01 from Outstanding Securities not previously called for redemption.

Securities and portions of them the Trustee selects shall be in Principal Amounts of $1,000 or integral multiples of $1,000. Provisions of this Indenture that apply to Securities called for redemption in whole also apply to Securities called for redemption in part. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection.

SECTION 11.03. Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed.

The notice shall identify the Securities to be redeemed and shall state:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) the Conversion Rate;

(iv) the name and address of the Paying Agent and Conversion Agent;

(v) that Securities called for redemption may be converted at any time before the close of business on the Business Day immediately preceding the Redemption Date;

(vi) that Holders who want to convert Securities must satisfy the requirements set forth therein and in this Indenture;

(vii) that Securities called for redemption must be surrendered to the Paying Agent for cancellation to collect the Redemption Price;

(viii) if fewer than all the outstanding Securities are to be redeemed, the certificate number (if such Securities are held other than in global form) and Principal Amount of the particular Securities to be redeemed;

(ix) that, unless the Company defaults in making payment of such Redemption Price, interest will cease to accrue on and after the Redemption Date; and

(x) the CUSIP number of the Securities.

At the Company’s written request delivered at least 30 days prior to the date such notice is to be given (unless a shorter time period shall be acceptable to the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense.

SECTION 11.04. Effect of Notice of Redemption. Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice except for Securities which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price stated in the notice.

SECTION 11.05. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time) on a Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company any money not required for that purpose because of conversion of Securities pursuant to Article 13. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust.

SECTION 11.06. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in principal amount to the unredeemed portion of the Security surrendered. The

Company shall not be required to (i) issue, register the transfer of, or exchange any Securities during a period of 15 days before the Redemption Date or (ii) register the transfer of, or exchange any, Securities so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part.

The Company shall purchase from the Holder thereof, pursuant to this Section 11.09, a portion of a Security if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000 if so requested by the Holder. Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the repurchase of such portion of such Security.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 11.09(c) shall have the right to withdraw such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day prior to the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.10.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

Upon receipt by the Paying Agent of the Repurchase Notice or Fundamental Change Repurchase Notice specified in clause (b) of Section 11.08 or clause (b) of Section 11.09, as applicable, the Holder of the Security in respect of which such Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, was given shall (unless such Repurchase Notice or Fundamental Change Repurchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Repurchase Price or Fundamental Change Repurchase Price, as the case may be, with respect to such Security. Such Repurchase Price or Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, promptly following the later of (x) the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, with respect to such Security (provided the conditions in clause (b) of Section 11.08 or clause (b) of Section 11.09, as applicable, have been satisfied) and (y) the time of delivery or book-entry transfer of such Security to the Paying Agent by the Holder thereof in the manner required by clause (b) of Section 11.08 or clause (b) of Section 11.09, as applicable. Securities in respect of

which a Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, has been given by the Holder thereof may not be converted pursuant to Article 13 on or after the date of the delivery of such Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, unless such Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, has first been validly withdrawn as specified in the following two paragraphs.

A Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, may be withdrawn only by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the procedures set forth in the Company Notice or Fundamental Change Company Notice, as the case may be, at any time prior to the close of business on the Business Day immediately prior to the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, specifying:

(i) the Principal Amount of the Security with respect to which such notice of withdrawal is being submitted; and

(ii) the certificate number (if such Security is held in other than global form) of the Security in respect of which such notice of withdrawal is being submitted or, if such Security is held in global form, the Holder must comply with applicable Depositary procedures; and

(iii) the Principal Amount, if any, of such Security which remains subject to the original Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, and which has been or will be delivered for repurchase by the Company.

There shall be no repurchase of any Securities pursuant to Section 11.08 or 11.09 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be) and is continuing an Event of Default (other than a default in the payment of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be, with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, 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 or Fundamental Change Repurchase Price, as the case may be, with respect to such Securities) in which case, upon such return, the Repurchase Notice or Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

SECTION 11.11. Deposit of Repurchase Price or Fundamental Change Repurchase Price. Prior to 10:00 a.m. (local time in The City of New York) on the Business Day following the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, the Company shall deposit with the Trustee or with the Paying

Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Repurchase Price or the Fundamental Change Repurchase Price, as the case may be, of all the Securities or portions thereof which are to be repurchased as of the Repurchase Date or the Fundamental Change Repurchase Date, as applicable. The Company shall promptly notify the Trustee in writing of the amount of any deposits of cash or Common Stock made pursuant to Section 11.11.

SECTION 11.12. Securities Repurchased in Whole or in Part. Any Security which is to be repurchased, whether in whole or 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 Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to, and in exchange for, the portion of the Principal Amount of the Security so surrendered which is not repurchased.

SECTION 11.13. Covenant to Comply With Securities Laws Upon Repurchase of Securities. In connection with any offer to repurchase Securities under Section 11.08 or 11.09 (provided that such offer or repurchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or repurchase), the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Section 11.08 or 11.09 to be exercised in the time and in the manner specified in Section 11.08 or 11.09, as applicable.

SECTION 11.14. Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed, together with interest, if any, thereon, held by them for the payment of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be; provided that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 11.11 exceeds the aggregate Repurchase Price or Fundamental Change Repurchase Price, as the case may be, of the Securities or portions thereof which the Company is obligated to repurchase as of the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, then as soon as practicable following the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, the Trustee or the Paying Agent, as the case may be, shall return any such excess to the Company.

ARTICLE XII

Interest Payments on the Securities

SECTION 12.01. Interest Rate. (a) Interest on the Securities shall accrue at a rate of 3.50% per annum and shall be payable semi-annually in arrears on each Interest Payment Date to holders of record on the Record Date immediately preceding such Interest Payment Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest on the Securities shall accrue from the most recent date to which interest has been paid, or if no interest has been paid, from the Issue Date, until the Principal Amount is paid or duly made available for payment.

(b) Interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security is registered at the close of business on the Record Date for such interest at the office or agency of the Company maintained for such purpose. Each installment of interest on any Security shall be made by check mailed to the address of the Holder specified in the register of Securities; provided, however, that, with respect to any Holder of Securities with an aggregate Principal Amount in excess of $2,000,000, at the request of such Holder in writing to the Company, interest on such Holder’s Securities shall be paid by wire transfer in immediately available funds in accordance with the written wire transfer instruction supplied by such Holder from time to time to the Trustee and Paying Agent (if different from the Trustee) at least ten days prior to the applicable Interest Payment Date. In the case of a permanent Global Security, interest payable on any Interest Payment Date will be paid to the Depositary, with respect to that portion of such permanent Global Security held for its account by Cede & Co. for the purpose of permitting such party to credit the interest received by it in respect of such permanent Global Security to the accounts of the beneficial owners thereof.

(c) The foregoing references to “interest on the Securities” in this Section 12.01 do not refer to any additional interest payable pursuant to Section 5.02 of this Indenture; any such additional interest shall be payable, if at all, in accordance with Section 5.02. Unless expressly stated or the context otherwise requires, all other references in this Indenture to interest on the Securities shall include additional interest then accrued or accruing pursuant to Section 5.02(c).

ARTICLE XIII

Conversion

SECTION 13.01. Conversion Privilege. (a) Subject to the further provisions of this Article 13, a Holder of a Security may convert, at its election, the Principal Amount of such Security (or a portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into Common Stock at any time and from time to time prior to the close of business on January 14, 2038.

(b) Conversion Period. Notwithstanding the foregoing, if such Security is called for redemption or submitted or presented for repurchase pursuant to Article 11, such conversion right shall terminate at the close of business on the Business Day prior to the Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, as the case may be, for such Security (unless the Company shall default on payment of the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price, as applicable, when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Security is redeemed or repurchased).

(c) Conversion Rate; Conversion Price. The conversion rate per Security (the “Conversion Rate”) shall initially be 33.1991 shares of Common Stock per $1,000 Principal Amount of Securities, subject to adjustment as set forth in this Article 13. The “Conversion Price” at any particular time is determined by dividing $1,000 by the then-applicable Conversion Rate.

(d) Securities Converted in Whole or in Part. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security.

(e) Rights of Holders. A Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities to Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 13.

SECTION 13.02. Conversion Procedure.

(a) To convert a Security, a Holder must (i) complete and manually sign the conversion notice on the back of the Security or facsimile of the conversion notice and deliver such notice to a Conversion Agent, (ii) surrender the Security to a Conversion Agent (if not in global form), (iii) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent and (iv) pay any transfer or similar tax, if required. Such notice is hereinafter referred to as a “Notice of Conversion.” A Security shall be deemed to have been converted as of the close of business on the date (the “Conversion Date”) on which the Holder has complied with the immediately preceding sentence of this clause (a) of Section 13.02. Anything herein to the contrary notwithstanding, in the case of Global Securities, a Notice of Conversion shall be delivered and such Securities shall be surrendered for conversion in accordance with the rules and procedures of the Depositary as in effect from time to time.

(b) The Company will, as soon as practicable after the Conversion Date, issue, or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates for the number of full shares of Common Stock to which such Holder shall be entitled. The Person or Persons entitled to receive such Common Stock 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 the applicable Conversion Date; provided, however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to

constitute the Person or Persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided further that such conversion shall be at the Conversion Rate in effect on the Conversion Date as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such Person shall no longer be a Holder of such Security. Except as otherwise provided in Section 13.06, no payment or adjustment will be made for dividends or distributions on shares of Common Stock issued upon conversion of a Security.

All Securities or portions thereof surrendered for conversion during the period from the close of business on the Record Date for any Interest Payment Date to the close of business on the Business Day next preceding such Interest Payment Date shall be accompanied by payment, in funds acceptable to the Company, of an amount equal to the interest otherwise payable on such Interest Payment Date on the Principal Amount being converted; provided, however, that no such payment need be made (A) in respect of conversions following the Record Date immediately preceding the Stated Maturity, (B) if the Company shall have specified a Redemption Date or Fundamental Change Repurchase Date that is after a Record Date and on or prior to the immediately following Interest Payment Date or (C) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

(c) If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the aggregate Principal Amount of Securities converted.

(d) Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security equal in principal amount to the unconverted portion of the Security surrendered.

(e) Holders that have already delivered a Repurchase Notice or Fundamental Change Repurchase Notice with respect to a Security may not surrender such Security for conversion until the Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, has been withdrawn in accordance with the procedures set forth in Section 11.10.

SECTION 13.03. Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of Securities. In lieu thereof, the Company will pay an amount in cash for the current market value of the fractional shares. The current market value of a fractional share shall be determined (calculated to the nearest 1/1000th of a share) by multiplying the Last Reported Sale Price of the Common Stock on the Trading Day immediately prior to the Conversion Date by such fractional share and rounding the product to the nearest whole cent.

SECTION 13.04. Taxes on Conversion. If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issuance of shares of Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificate representing the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

SECTION 13.05. Company to Provide Stock.

The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock (including after taking into account any adjustments to the Conversion Rate pursuant to Section 13.06).

All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or on the New York Stock Exchange, the NASDAQ Global Select Market or other over-the-counter market or such other market on which the Common Stock is then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such automated quotation system or exchange at such time.

SECTION 13.06. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

(a) If the Company issues shares of Common Stock as a dividend or distribution on Common Stock, or if the Company effects a stock split or stock combination, the Conversion Rate shall be adjusted based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to such event;

CR'	=	the Conversion Rate in effect immediately after such event;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to such event; and

OS'	=	the number of shares of Common Stock outstanding immediately after such event.

An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision or combination.

(b) If the Company issues to all or substantially all holders of its Common Stock any rights or warrants entitling them for a period of not more than 60 days after the Ex-dividend Date for such issuance to subscribe for or purchase shares of Common Stock at a price per share less than the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the time of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula (provided that the Conversion Rate shall be readjusted to the extent that such rights or warrants are not exercised prior to their expiration):

where,

CR₀	=	the Conversion Rate in effect immediately prior to the Ex-dividend Date for such event;

CR'	=	the Conversion Rate in effect on and immediately after the Ex-dividend Date for such event;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the Ex-dividend Date for such event;

X	=	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and

Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-dividend Date for such distribution.

Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective on the Ex-dividend Date of such issuance.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property to all or substantially all holders of the Common Stock, excluding (1) dividends, distributions and rights or warrants referred to in clause (a) or (b) above and (2) dividends or distributions in cash referred to in clause (d) below, then the Conversion Rate shall be adjusted based on the following formula:

where,

CR₀ = the Conversion Rate in effect immediately prior to the Ex-dividend Date for such distribution;

CR' = the Conversion Rate in effect on and immediately after the Ex-dividend Date for such distribution;

SP0 = the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-dividend Date for such distribution; and

FMV = the fair market value (as determined by the Board of Directors of the Company) of the shares of Capital Stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Common Stock on the Ex-dividend Date for such distribution.

Such adjustment shall be made successively whenever any such distribution is made and shall become effective on the Ex-dividend Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate 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 13.06 by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the market price of the Common Stock as provided above.

In the event that the Company has in effect a preferred shares rights plan (“Rights Plan”), upon conversion of the Securities into Common Stock, to the extent that the Rights Plan is still in effect upon such conversion, the Holders of Securities shall receive, in addition to the Common Stock, the rights described therein (whether or not the

rights have separated from the Common Stock at the time of conversion), subject to the limitations set forth in the Rights Plan. If the Rights Plan provides that upon separation of rights under such plan from the Common Stock that the Holders would not be entitled to receive any such rights in respect of the Common Stock issuable upon conversion of the Securities, the Conversion Rate shall be adjusted as provided in this Section 13.06(c) (with such separation deemed to be the distribution of such rights), subject to readjustment in the event of the expiration, termination or redemption of the rights. Any distribution of rights or warrants pursuant to a Rights Plan that would allow a Holder to receive upon conversion, in addition to the Common Stock, the rights described therein (whether or not the rights have separated from the Common Stock at the time of conversion), shall not constitute a distribution of rights or warrants pursuant to this Article 13.

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof 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 Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.06(c) (and no adjustment to the Conversion Rate under this Section 13.06 shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 13.06(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders 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 was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 13.06 was made, (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 Rate 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 or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders 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 by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

(d) If the Company shall, by dividend or otherwise, at any time distribute cash to all or substantially all holders of its Common Stock, the Conversion Rate shall be adjusted based on the following formula:

where,

CR₀ = the Conversion Rate in effect immediately prior to the Ex-dividend Date for such distribution;

CR' = the Conversion Rate in effect on and immediately after the Ex-dividend Date for such distribution;

SP₀ = the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-dividend Date of such distribution; and

C = the amount in cash per share distributed to holders of the Common Stock in such distribution.

(e) In case the Company or any of its Subsidiaries shall purchase any shares of the Common Stock pursuant to a tender offer, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the date such tender offer expires, the Conversion Rate shall be increased based on the following formula:

where,

CR₀ = the Conversion Rate in effect immediately prior to the effective date of the adjustment;

CR' = the Conversion Rate in effect on and immediately after the effective date of the adjustment;

AC = the aggregate value of all cash and any other consideration (as determined by the Board of Directors of the Company) paid for shares purchased in such tender offer;

OS₀ = the number of shares of Common Stock outstanding immediately prior to the date such tender offer expires;

OS' = the number of shares of Common Stock outstanding immediately after the date such tender offer expires (after giving effect to the purchase of shares in such tender offer); and

SP' = the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender offer expires.

The foregoing adjustment to the Conversion Rate shall occur on the tenth Trading Day from, and including, the Trading Day next succeeding the date such tender offer expires; provided that in respect of any conversion within ten Trading Days immediately following, and including, the expiration date of any such tender offer, references with respect to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender offer and the Conversion Date in determining the applicable Conversion Rate. For purposes of this clause (e) of Section 13.06, the aggregate consideration in any such tender offer shall equal the sum of the aggregate amount of cash consideration and the aggregate fair market value (as determined by the Board of Directors of the Company) of any other consideration payable in such tender offer. 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 or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon the number of shares actually purchased. For purposes of this clause (e) of Section 13.06, the term “tender offer” shall mean and include both tender offers and exchange offers, all references to “purchases” of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all references to “tendered shares” (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers.

(f) If the application of any of the formulas set forth in Section 13.06(a) through Section 13.06(e) would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made, other than as a result of a stock combination as set forth in Section 13.06(a).

(g) In any case in which this Section 13.06 shall require that an adjustment be made following an Ex-dividend Date, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 13.09) issuing to the Holder of any Security converted after such Ex-dividend Date the shares of Common Stock and other Capital Stock of the

69 Company issuable upon such conversion over and above the shares of Common Stock and other Capital Stock of the Company issuable upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agent to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares.

SECTION 13.07. No Adjustment. (a) No adjustment need be made (1) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan; (2) upon the issuance of any shares of Common Stock or options or rights to purchase such shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; (3) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (2) and outstanding as of the original Issue Date; (4) for a change in the par value of the Common Stock or a change to no par value of the Common Stock; or (5) for accrued and unpaid interest.

(b) To the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash due.

(c) No adjustment in the Conversion Rate shall be made pursuant to this Section 13.06 if the Holders may participate, as a result of holding Securities, in the transaction that would otherwise give rise to an adjustment pursuant to Section 13.06 without having to convert their Securities.

(d) No adjustment in the Conversion Rate shall be required pursuant to Section 13.06 unless such adjustment would require an increase or decrease of at least 1.0% in the Conversion Rate; provided, however, that any adjustments which by reason of this clause (d) of Section 13.07 are not required to be made, shall be carried forward and taken into account in any subsequent adjustment.

(e) Other than as described above in Section 13.06, no adjustment to the Conversion Rate shall be required for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities.

SECTION 13.08. [Reserved]

SECTION 13.09. Notice of Conversion Rate Adjustment. Whenever the Conversion Rate or conversion privilege is adjusted, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of

70 the Conversion Rate, the Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect.

SECTION 13.10. Notice of Certain Transactions. In the event that:

(a) the Company takes any action which would require an adjustment in the Conversion Rate;

(b) the Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and stockholders of the Company must approve the transaction; or

(c) there is a dissolution or liquidation of the Company,

the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice at least ten days before such date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (a), (b) or (c) of this Section 13.10.

SECTION 13.11. Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege. If any of the following shall occur, namely: (a) any reclassification or change of shares of Common Stock issuable upon conversion of the Securities (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, or any other change for which an adjustment is provided in Section 13.06); (b) any consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than 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) in, outstanding shares of Common Stock; or (c) any sale or conveyance as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to any Person, then the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, change, combination, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to convert such Security into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification, change, combination, consolidation, merger, sale or conveyance. For the avoidance of doubt, a Holder will not be entitled to an increase in the Conversion Rate as a result of a transaction described in clause (a), (b) or (c) of this paragraph that constitutes a Fundamental Change if such Holder does not convert its Securities during the period specified in Section 13.12(a) in respect of such Fundamental Change. Such supplemental indenture shall provide for adjustments of the

71 Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 13. If, in the case of any such consolidation, merger, combination, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a person other than the successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors of the Company shall in good faith consider necessary by reason of the foregoing. The provisions of this Section 13.11 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, sales or conveyances.

In the event the Company shall execute a supplemental indenture pursuant to this Section 13.11, the Company shall promptly file with the Trustee (x) an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or other securities or property (including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change, combination, consolidation, merger, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and (y) an Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders.

SECTION 13.12. Adjustment to Shares Delivered Upon Fundamental Change. (a) In the event of the occurrence of a Fundamental Change as described in clause (1) or (2) of the definition thereof, the Company shall give written notice to the Holders of Securities on or prior to the date that is 10 scheduled Trading Days prior to the anticipated Effective Date of such Fundamental Change (or, in the case of a Fundamental Change pursuant to clause (1) of the definition thereof, the later of the date that is 10 scheduled Trading Days prior to the anticipated Effective Date of such Fundamental Change and the date that is the fifth Business Day following receipt by the Company of notice of such Fundamental Change) (such date, the “Additional Share Notice Date”). Such notice shall be provided to all Holders of Securities and the Trustee and shall state that such Fundamental Change has occurred and the anticipated number of Additional Shares in respect thereof. Simultaneously with providing such notice, the Company shall publish a notice containing substantially the same information in a newspaper published in the English language, customarily published each Business Day and of general circulation in The City of New York, or publish such information on the Company’s website or through such other public medium as the Company may use at such time.

(b) In the event that a Holder converts Securities at any time in the period beginning on the Additional Share Notice Date and ending on and including the 10th Trading Day following the Effective Date of such Fundamental Change (or ending on the applicable Fundamental Change Repurchase Date, if later), the Conversion Rate in respect of the Securities so converted shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) determined by reference to the table attached as Exhibit C hereto, based on the date on which such Fundamental Change

72 occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per share of Common Stock in such Fundamental Change. If the holders of Common Stock receive only cash in such Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock. In all other cases, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on the Trading Day immediately preceding the Effective Date of the Fundamental Change. The Additional Shares shall be issued after the later to occur of (1) the fifteenth Trading Day following the Effective Date of the applicable Fundamental Change and (2) the fifth Trading Day following the relevant Conversion Date in respect of the Securities so converted. Such increase in the Conversion Rate shall not take place if such Fundamental Change is not consummated.

(c) The Stock Prices set forth in the column headings of the table set forth in Exhibit C shall be adjusted as of any date on which the Conversion Rate is adjusted pursuant to Section 13.06. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the Conversion Rate adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner as the Conversion Rate is adjusted pursuant to Section 13.06.

(d) In the event that the exact Stock Price and Effective Date relating to a Fundamental Change are not set forth in the table in Exhibit C, then:

(i) if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is greater than $90.00 per share (subject to adjustment), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $21.67 per share (subject to adjustment), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion (including the Additional Shares) exceed 41.1467 per $1,000 Principal Amount of Securities, subject to adjustment as provided in Section 13.06.

SECTION 13.13. Trustee’s Disclaimer. The Trustee shall have no duty to determine when an adjustment under this Article 13 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers’ Certificate including the Officers’ Certificate with respect thereto which the

73 Company is obligated to file with the Trustee pursuant to Section 13.09. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article 13.

The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 13.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 13.11.

SECTION 13.14. Voluntary Increase. The Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days and if the increase is irrevocable during the period if the Board of Directors determines that such increase would be in the best interest of the Company or the Board of Directors deems it advisable to avoid or diminish income tax to holders of shares of Common Stock in connection with any stock or rights dividend or distribution or similar event, and the Company provides at least 15 days prior notice of any increase in the Conversion Rate.

SECTION 13.15. Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to this Article 13 shall be conclusive if made in good faith and in accordance with the provisions of this Article 13, absent manifest error, and set forth in a resolution of the Board of Directors.

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